Hepatitis A vaccines have been highly effective in preventing hepatitis A. To investigate the epidemiology of hepatitis A in China after hepatitis A vaccine became available, we reviewed reported cases of hepatitis A and the use of hepatitis A vaccine in China during the period from 1990 through 2007.Data from the National Notifiable Disease Reporting System from 1990 to 2007 and the Emergency Events Reporting System from 2004 to 2007 were reviewed and epidemiologic characteristics analyzed. Hepatitis A vaccine distribution between 1992 and 2007 was also reviewed.5/year. Declines in age-specific incidence were seen in all age groups, most dramatically among children younger than 10 years. Disease incidence still varies substantially: poorer western provinces have had the highest incidences since 2000. In high-incidence provinces, children younger than 10 years continue to have a high disease incidence. Only 50% of cases were laboratory-confirmed, and only 3% occurred in reported local outbreaks. Over 156 million doses of hepatitis A vaccine have been distributed since 1992, and use has continued to increase since 2003.The incidence of hepatitis A has declined by 90% since 1990, from 56 to 5.9 per 10Incidence of hepatitis A has decreased in all age groups, likely due to changing socioeconomic conditions and increasing hepatitis A vaccine use. Nevertheless, western populations remain at high risk, with transmission predominantly occurring among children. The epidemiology of hepatitis A transmission is not well understood. Improved surveillance with better laboratory confirmation is needed to monitor the impact of universal hepatitis A vaccination of young children; this strategy began to be implemented in 2008. Among children younger than 5 years, 70% of those infected are asymptomatic; therefore, in high prevalence areas, symptomatic cases are uncommon.1 Nevertheless, hepatitis A can result in a high disease burden, and is still considered a public health problem in many countries. During the 1980s and 1990s, improved sanitation resulted in an increase in the average age of hepatitis A onset in many countries, but most cases still occur in populations living in poor sanitary conditions.2–5Hepatitis A is an acute, usually self-limited infection of the liver caused by the hepatitis A virus (HAV). Transmission occurs primarily through the fecal–oral route, and is closely associated with poor sanitary conditions.6 Recent evidence from Israel, Alaska, the United States, and northern Australia indicates that vaccination of young children has markedly decreased hepatitis A incidence among all age groups.7–9Hepatitis A vaccines are highly effective in preventing both clinical hepatitis and in reducing disease spread. Vaccination against hepatitis A has resulted in robust health and economic benefits in Argentina.10In China, hepatitis cases have been reported as part of the National Notifiable Disease Reporting System (NNDRS) since 1959, and have been reported separately by virus type since 1990. NNDRS is a hospital-based, passive national surveillance system that has included all county hospitals in 31 provinces since 1959. Before 2003, cases were reported monthly to county Centers for Disease Control and Prevention (CDCs) via hardcopy (case and hardcopy-based NNDRS), and through prefecture and provincial CDCs to national authorities. Case information included age, sex, location of residence, and date of onset. In 2004, the China CDC revised the reporting system, establishing an online electronic version (case and computer-based). After diagnosis, cases are reported via the Internet from all county and most township-level hospitals. In addition, all outbreaks (defined as more than 5 cases in 1 village within 1 week) must be reported immediately to the Emergency Events Reporting System (EERS) by the county CDC. The Emergency Events Reporting System was established in 2004 as an online electronic system accessible by county, prefectural, provincial, and national CDCs through the Internet. The Emergency Events Reporting System provides information on the basic epidemiologic characteristic of outbreaks. The largest documented hepatitis A outbreak in the world occurred in Shanghai in 1988, with more than 300 000 persons infected, and with estimated direct costs of $58 million and indirect costs of $64 million.11,12 contaminated by hepatitis A virus, as is the case in other countries.13 However, many individuals are likely infected through close personal contact with an infected person.14 An effective live, attenuated hepatitis A vaccine has been available for private use (class 2) since 1992,15,16 and inactivated vaccines became available in 2002.17 These vaccines have been used increasingly since 2000 to prevent hepatitis A, primarily in school-aged children.In China, hepatitis A is a public health concern, as over 60 000 cases are currently reported annually. The most common recognized modes of transmission of outbreaks in China are ingestion of food and waterThis report summarizes the status of reported cases of hepatitis A and hepatitis A vaccine use in China during the period from 1990 through 2007. In addition, the implications for future control with hepatitis A vaccination are discussed.This is a descriptive epidemiologic study that reviewed national surveillance data and vaccine distribution data in China. We reviewed incidence data on reported hepatitis A from 1990 to 2007 from the NNDRS, in which a reportable case is defined as an acute illness with discrete onset of symptoms with jaundice and/or elevated serum aminotransferase levels (suspected case). A case is considered confirmed if a person tests positive for the IgM antibody to hepatitis A virus or is epidemiologically linked with a lab-confirmed case. Information compiled for each case since 2004 includes whether the case has been laboratory confirmed, although it does not designate what type of test was used to confirm the diagnosis.In addition, since 2004, China’s Emergency Events Reporting System has collected information on all outbreaks of communicable diseases; outbreaks are defined as 5 or more cases in the same village within a 1-month period. Information on each outbreak includes number of cases, date of outbreak cases, primary location, and the age groups affected.5/yr), intermediate (4–8/105/yr), or low (<4/105/yr). Incidence in 10 (mainly western) provinces was classified as high; 10 provinces had intermediate incidences, and 11  had low incidences.**High incidence: Xinjiang, Xizang (Tibet), Qinghai, Gansu, Ningxia, Sichuan, Yunnan, Guizhou, Chongqing, Hainan. Intermediate incidence: Jiangxi, Henan, Liaoning, Shaanxi, Zhejiang, Neimenggu, Fujian, Jilin, Hubei, Guangxi. Low incidence: Anhui, Shanxi, Jiangsu, Heilongjiang, Shanghai, Hunan, Beijing, Hebei, Shandong, Guangdong, Tianjin.Within each province, an epidemic was defined as a 50% or greater increase in incidence, as compared to the lowest incidence of the previous 3 years. Incidence rates were calculated based on the most recent National Statistical Bureau census data, those of 2000. The 2007 Chinese population is estimated to be 1.3 billion, with a birth rate of 1.209% (birth cohort of 15.7 million).18NNDRS data on hepatitis A from 1990 to 2003 and 2004 to 2007 were analyzed. This was a period of national transition from high to low hepatitis A incidence. Case numbers and disease incidence were examined by year, age, province, and provincial grouping; disease seasonality, case sex, occupational group, and frequency of laboratory confirmation were also examined for the period from 2004 to 2007. Age-specific incidence was examined nationwide and in provinces, and grouped according to incidence. We defined the relative incidence for each province—according to the average incidence rate between 2003 and 2007—as high , between 68 667 and 93 587 cases of hepatitis A have been reported through the NNDRS; incidence in these years was 7.2/100 000, 5.6/100 000, 5.4/100 000, and 5.9/100 000, respectively. During this period, there were no significant national differences in incidence by month or season; however, incidence was higher in western provinces, and modest seasonality (peaks in spring or summer) was seen in several western provinces. In addition, there was a seasonal increase in hepatitis A outbreaks in April and September each year.The reported incidence of hepatitis A in China has decreased rapidly since 1990, when hepatitis A first became reportable as a distinct disease: from 56/100 000 in 1991 (584 353 cases) to 5.9/100 000 in 2007 , and is only slightly lower among older age groups. Among hepatitis A cases reported between 2004 and 2007, 10% are children under 5 years, 17% are children aged 5–9 years, and 19% are persons aged 10–19 years.Data from NNDRS from the early 1990s show that the highest incidence was in children aged <10 years, followed by persons aged 10–19 years and 20–39 years , the age-specific incidence during 2004–2007 was highest in children—reaching 20–30/105/yr for children younger than 10 years—and declined with increasing age to 10–15/105/yr among adults. For provinces with intermediate incidences, incidence was also higher in children younger than 10 years, but similar among older age groups. In contrast, among provinces with low incidences, adults had a higher incidence than did children —a male-to-female case ratio of 2:1. During this period, with respect to occupation, 118 214 cases were farmers, 75 369 were students, 28 459 were preschoolers, and 90 693 were classified as other, accounting for 37.8%, 24.1%, 9.1%, and 29% of cases, respectively.Although disease incidence has decreased, local outbreaks remained common, particularly in western provinces. Among hepatitis A cases reported between 2004 and 2007, a total of 9197 (2.9%) were from 154 reported outbreaks (Table Among the hepatitis A cases in reported in 2004 to 2007, 48.2% were clinically confirmed and 51.8% were confirmed on the basis of laboratory findings. The proportion of cases that were laboratory-confirmed increased from between 47–49% between 2004 and 2005 to 59% in 2007 (Table 15–17,19Two types of vaccine are available in China: live, attenuated hepatitis A vaccine, which was licensed in 1992, and inactivated vaccine, available since 2002. Both are produced domestically. Before 2008, hepatitis A vaccine was a class 2 vaccine, ie, not routinely recommended for childhood vaccination, and was available to persons willing to pay for vaccination. Live, attenuated hepatitis A vaccine is given as a single dose to children older than 18 months; inactivated hepatitis A vaccine is given in a 2-dose series. The Chinese scientific literature shows that both vaccines are highly effective against HAV in China.Between 1992 and 2007, 156 million doses of hepatitis A vaccine were distributed, mostly for school-aged children Figure . The totDisease surveillance data reveal a dramatic decrease in reported hepatitis A cases in China during a recent 17-year period. Decreases were observed in all age groups and were greater in the eastern provinces of China.20Although the causes for the marked reduction in hepatitis A incidence in China cannot be determined by this study, we suspect that several factors are important. First, with continuing economic development, the quality of water, food, and sanitation has substantially improved. It is therefore likely that fewer people became infected through water and food, and that transmission through close contact was also reduced due to improved sanitation and life style. We believe that these factors contributed to the rapid decline in HAV risk in China during the 1990s.21 Although no age- or province-specific immunization coverage data on hepatitis A are available, hepatitis A vaccine has been given mostly to school-aged children; the number of children in each school class is approximately equal to the number of persons who can be vaccinated each year with the amount of vaccine now available.17 In addition, it is likely that hepatitis A vaccine has been used mainly in the wealthier eastern provinces, where parents can more easily afford to vaccinate their children. Studies of population vaccination with hepatitis A vaccine have highlighted the importance of herd immunity, which becomes apparent with coverage of 66% or higher.8,22 Thus, hepatitis A vaccine may have provided significant protection to children, and to the entire population as well.Second, hepatitis A vaccination may now be playing a substantial role. The cumulative output of hepatitis A vaccine from Chinese manufacturers increased from 2.9 million doses in 1992 to 156 million doses through 2007.23 Furthermore, with additional reductions in disease transmission, fewer adults will develop natural infection, and a higher proportion of the older adult population will be susceptible. If vaccination is not continued, there may be increased risks of disease and outbreaks in adults, among whom disease progression is more severe. Therefore, the current vaccination program will play an increasingly important role in protecting the population in the future.Thus, in the well-developed eastern and urban regions, a booming economy, improvements in sanitation and life style, and increasing vaccination rates have likely played major roles in risk reduction. Indeed, populations in these regions had lower prevalences of HAV antibodies in a 1992–1995 national serosurvey.12Due to differences in sanitary environments within China, there were no significant national differences in incidence by month or season; however, in western areas with lower economic and sanitary conditions, incidence was higher in all age groups. In addition, there was a seasonal increase in hepatitis A outbreaks in April and September every year in those provinces, possibly due to school-related outbreaks, which were commonly reported but accounted for only 3% of cases. In rural areas, outbreaks mostly occurred in rural primary and middle schools, which have inadequately protected drinking water and where transmission through close contact is more likely.There were considerably more male cases than female cases, perhaps due to greater health care seeking among males and to more exposures in the workplace, where hygiene and access to clean food and water may be worse. Although preschoolers and school-aged students made up only 33% of cases, incidences were higher in these age groups and were likely highest in preschoolers, since this age group is more likely to be asymptomatic after infection. Among adults, distribution of disease in farmers and other groups was consistent with occupations in China overall.Despite the steadily improving economy and decreasing incidence of hepatitis A, some populations remain at high risk and continue to experience periodic epidemics and frequent smaller outbreaks. In these areas, which are mainly western and rural, disease risk continues to be highest in young children. However, risk factors remain poorly defined and further study is needed to examine the changing risks for HAV in China.Many challenges remain before we will be able to clearly define the burden and cost of hepatitis A in China. In 2004–2007, only 51.8% of cases were laboratory-confirmed, because of the high cost of testing and the lack of laboratory facilities in poorer townships and villages. The risk factors for hepatitis A and the overall cost associated with hepatitis A in China are not well known. Efforts are needed to increase the systematic use of confirmatory laboratory tests at peripheral health centers, to define the risk factors for disease in populations at high risk, and to determine the cost of the disease and the cost effectiveness of vaccination for at-risk populations.A key limitation of the present study is that it is a descriptive study based on surveillance data and reports of vaccine distribution. These data cannot directly evaluate the causes of decreased incidence, such as improvements in sanitary conditions and increased use of hepatitis A vaccination. Furthermore, the quality of the reported data, particularly the accuracy of the diagnosis and laboratory testing, cannot be verified from the available data.7–9 Furthermore, to better measure the impact of immunization and refine future immunization strategies, China plans to enhance laboratory-based surveillance of hepatitis A and to evaluate the economic cost of hepatitis A. By combining universal vaccination with stronger surveillance, China expects to continue to reduce the risk of hepatitis A in the entire population.In order to further reduce the transmission of HAV, China has integrated hepatitis A vaccination into the routine child immunization program in 2008, and provides vaccine for children beginning at the age of 18 months. Initially, all children in 2 high-incidence provinces—Xinjiang and Yunnan—will be vaccinated; the remaining provinces will initially be able to vaccinate only 40% of children. Hepatitis A vaccine is expected to be available for all children by 2010. This approach to disease control is based on the strategies for hepatitis A prevention used for high-risk populations in more developed countries, which have demonstrated how vaccination of young children has a dramatic impact on hepatitis A incidence in all age groups.


G. max BAC libraries combined with genetic and gene-based markers were used to construct a minimum tiling path (MTP) of BAC clones. A total of 107,214 clones were assembled into 1355 FPC (FingerPrinted Contigs) contigs, incorporating 4628 markers and aligned to the G. max reference genome sequence using BAC end-sequence information. Four different MTPs were made for G. max that covered from 92.6% to 95.0% of the soybean draft genome sequence (gmax1.01). Because our purpose was to pick the most reliable and complete MTP, and not the MTP with the minimal number of clones, the FPC map and draft sequence were integrated and clones with unpaired BES were added to build a high-quality physical map with the fewest gaps possible (http://soybase.org). A physical map was also constructed for the undomesticated ancestor (G. soja) of soybean to explore genome variation between G. max and G. soja. 66,028 G. soja clones were assembled into 1053 FPC contigs covering approximately 547 Mbp of the G. max genome sequence. These physical maps for G. max and its undomesticated ancestor, G. soja, will serve as a framework for ordering sequence fragments, comparative genomics, cloning genes, and evolutionary analyses of legume genomes.Soybean is a model for the legume research community because of its importance as a crop, densely populated genetic maps, and the availability of a genome sequence. Even though a whole-genome shotgun sequence and bacterial artificial chromosome (BAC) libraries are available, a high-resolution, chromosome-based physical map linked to the sequence assemblies is still needed for whole-genome alignments and to facilitate map-based gene cloning. Three independent  Glycine max)  markers were identified from BAC end sequences (BES) of clones comprising the initial physical map and 265 of these SSR were genetically mapped  can be picked using BESs aligned to the genome sequence. Traditionally, the main purpose of a MTP has been to efficiently select clones to be sequenced; in other words, to minimize the number of clones to be sequenced by selecting clones that are adjacent and overlap minimally. In the case of G. max, in which the whole-genome shotgun data are available, the primary purpose of the MTP is to have a physical map anchored to the genome sequence, thereby providing a framework for genomic research. A reliable MTP covering nearly the whole genome complements a genome shotgun sequence in that it can be used to correct misalignments and to span gaps, which is important for finishing regions and cloning genes. For G. soja, the physical map provides an anchored, clone-based resource to shuttle between the two genomes, domesticated and undomesticated.For the HindIII, BstyI, and EcoRI, were used to construct the three libraries, GM_WBa, GM_WBb, and GM_WBc, respectively  map (clone pool A), and the other contained all the BAC clones from the three BAC libraries (clone pool B). Two kinds of MTPs were picked from each clone pool by using Dijkstra’s shortest path algorithm . One MTPTo span the gaps in the preliminary FPC map having 1893 contigs, the map was integrated with a preliminary 4x sequence assembly from the Joint Genome Institute and the Stanford Human Genome Center. The average length of contigs was 157,040 bp, and the maximum size was 20,109,437 bp .There are many gaps represented as a series of Ns in the 8x soybean sequence (gmax1.01). A total of 1000 Ns indicate gaps between scaffolds that were not spanned using the Arachne assembler, 100 Ns indicate gaps without length information, and a specific number of Ns indicate gaps of known size . We assuGlycine max cv. Williams 82 BAC libraries, GM_WBa, GM_WBb, and GM_WBc (http://genome.arizona.edu), were made with three different restriction enzymes, HindIII, BstyI, and EcoRI, respectively, to reduce the likelihood of missing parts of the genome attributable to cloning bias. All three libraries were used to construct the G. max physical map. A BAC library was constructed using HindIII for Glycine soja PI468916, called GSS_Ba. The average insert size of GM_WBa, GM_WBb, GM_WBc, and GSS_Ba were 150, 150, 131, and 150 kb and represent 5.4, 12, 10.9, and 12x coverage of each genome, respectively. Subsets of each library were fingerprinted for construction of the FPC maps , respectively (G. max’s and 1053 (37%) of G. soja’s were ordered and oriented to 20 soybean chromosomes  were included in the aligned contigs for G. max and G. soja, respectively  to integrate the genetic and physical maps. The soybean genome sequence was then combined with the physical map using BES , indicating that the markers were anchored more than two BAC clones, 1181 MHM were linked to more than two contigs, 503 MHM were anchored to multiple clones on one contig, and 41 MHM were anchored to multiple singletons. The average number of contigs hit by the 3952 SSR markers was 1.5, and the average number of contigs hit by 676 RFLP markers was 1.6. Of 3952 SSR markers, 417 hit 0 contigs, 2601 hit 1 contig, 301 hit 2 contigs, and 633 markers hit more than 2 contigs. Of the 676 RFLP markers, 98 hit 0 contigs, 331 hit 1 contig, 145 hit 2 contigs, and 102 hit more than 2 contigs . Therefore, our MTP does not need to be “minimal” in the sense of budget constraints for BAC sequencing, and we instead selected BAC clones with the greatest reliability while attempting to minimize overlap between adjacent BACs  is already available. We integrated the sequence with the FPC map to build BAC-based pseudomolecules representing the 20 soybean chromosomes  to detect structural difference between G. max and G. soja. Of 180,099 total BESs, 88,950 clones have paired end sequences, and 2199 clones have sequence for one end only . BAC clones where paired BESs aligned more than 1.5 Mbp apart were excluded as potential artifacts. Of 3796 clones, 1965 were included within 225-kbp to 1.5-Mbp range. A majority of clones fell within the expected distance of an average BAC library insert distribution although there were many clones that had potential insertions/deletions.By examining the distance and orientation of paired BESs, we were able to look at intrachromosomal rearrangements. BES pairs when aligned to the genome should be inverted relative to each other (sequencing from either end of the cloning vector) and we expected the distance between the ends to be within 75 to 225 kbp of each other . Of the In terms of orientation of BESs where both BESs were located on same chromosome, 63,888 clones had the expected orientation  FPC clone pool A, in which all BACs have paired BESs; (2) FPC clone pool A, in which BACs have both paired and unpaired BESs; (3) Pool B of all three BAC libraries, in which BACs have paired BESs; and (4) Pool B of all three BAC library, in which BACs have both paired and unpaired BESs . CompariComparing MTPs 2 and 4 to 1 and 3, in terms of BESs, ∼140 gaps were spanned, and the average length of overlap was increased by ∼1.4 kbp. Once an MTP was picked using clones with paired BES, clones with unpaired BES were used only where we were unable to place clones with paired BESs. Therefore, it was reasonable that both the total numbers of clones used to build the MTPs and the average lengths of overlap increased. The sum of gaps covered by the clones with unpaired BES in both pools was 306, which was ∼1.8 times more than the sum of gaps spanned when MTPs were picked in the larger pool with all the three BAC libraries.http://soybase.org).We conclude that the MTP selected using all the three BAC libraries containing clones with paired and unpaired BES is the best in that it had fewer gaps and the greatest coverage of the sequence map. In instances in which users need to know the relative locations of clones, this can be inferred through the FPC map constructed using clones with both paired and unpaired BESs. This high-resolution chromosome-anchored physical map will serve as an important tool for (1) improving the genome sequence by spanning gaps (in progress); (2) resolving assembly errors caused by repetitive sequences, large gene families and segmental duplications; (3) map-based cloning; and (4) cloning sequences that are too large or repetitive for polymerase chain reaction−based cloning  were mapped to gmax1.01 reference for assembly . This is an underestimate because small insertions or deletions would be missed because of the variability in BAC insert sizes. However, we were able to calculate a rough estimate of how much of the genome might be in flux between the two species .Putative chromosomal structural rearrangements between 150 kbp; . The aveG. soja) as genetic resource for potentially valuable genes for introgression into soybean cannot be overstated. This was the reasoning for the sequencing of G. soja accession IT182932 as well another 17 other accessions of wild soybean (to 5x sequence coverage) (G. max and G. soja is ∼98%; however, structural differences are not captured in this statistic. Reciprocal translocations, segmental duplications, and insertions/deletions complicate the ability to map G. soja using G. max as a reference and short read WGS does not currently capture this information. Thus, physical maps remain useful for investigating and describing structural evolution that has occurred between these two genomes and to allow researchers to effectively shuttle between the genomes to capture useful genetic information for crop improvement and basic genetics.The importance of wild soybean (


Aspergillus species originating from Greece were examined by morphological and molecular criteria to explore the diversity of this genus. The phylogenetic relationships of these species were determined using sequences from the ITS and IGS region of the nuclear rRNA gene complex, two nuclear genes (β-tubulin (benA) and RNA polymerase II second largest subunit (rpb2)) and two mitochondrial genes  and cytochrome oxidase subunit I (cox1)) and, where available, related sequences from databases. The morphological characters of the anamorphs and teleomorphs, and the single gene phylogenetic trees, differentiated and placed the species examined in the well-supported sections of Aenei, Aspergillus, Bispori, Candidi, Circumdati, Clavati, Cremei, Flavi, Flavipedes, Fumigati, Nidulantes, Nigri, Restricti, Terrei, Usti, and Zonati, with few uncertainties. The combined use of the three commonly employed nuclear genes , the IGS region, and two less often used mitochondrial gene sequences (rns and cox1) as a single unit resolved several taxonomic ambiguities. A phylogenetic tree was inferred using Neighbour-Joining, Maximum Parsimony, and Bayesian methods. The strains examined formed seven well-supported clades within the genus Aspergillus. Altogether, the concatenated nuclear and mitochondrial sequences offer additional tools for an improved understanding of phylogenetic relationships within this genus. Aspergillus is one of the most common and important genera of microfungi. Several species of the genus proved very useful cell factories for biotechnology purposes since they produce organic acids, extracellular enzymes, nutraceuticals (isoprenoids), and aroma compounds and are capable of fermenting various substrates under extreme cultivation conditions, usually intolerable to bacteria and yeasts [Aspergillus species in order to provide more appropriate tools for their accurate and fast identification.The genus d yeasts –4.

Additional strains of representative Aspergillus spp. were studied from the ATHUM Culture Collection of Fungi in the University of Athens and ex-type cultures were obtained from the Agricultural Research Service ARS (NRRL) at Peoria, USA (kindly provided by Dr. S.

A total of thirty six strains belonging to thirty-one Aspergillus species were studied  at 25°C and 37°C, on Malt Extract Agar (MEA) at 25°C, and on G25N at 25°C [Aspergillus.The strains of  at 25°C .

Random starting trees were used and the burn-in period was 1,000,000 cycles, as this was found to be clearly sufficient for the likelihood and the model parameters to reach equilibrium. After the burn-in, 1,000 trees were sampled every 100 cycles during the sampling period . Two independent MCMCMC searches were run for each dataset using different random starting points. The hypocrealean fungus Metarhizium anisopliae from the Class Sordariomycetes, a close relative to Eurotiomycetes, was used as outgroup in all datasets. When the species Coccidioides immitis from Onygenales, an order within Eurotiomycetes, was alternatively employed, the tree topologies from all analyses were identical (data not shown). All sequences of Aspergillus species and their teleomorphs not amplified in this study were taken from GenBank and are provided with their Accession Numbers and the species names provided by the database. Aligned matrices are available in Treebase, http://purl.org/phylo/treebase/phylows/study/12165. Maximum parsimony (MP), Neighbour-Joining (NJ), and Bayesian inference (BI) analyses were employed in order to create the phylogenetic trees. MP, and NJ analyses of nucleotide datasets were performed with PAUP* 4.0b10  using 1,Aspergillus spp. have been recorded for all the strains and their evaluation was critical in cases of closely related species. The colony texture, colour and growth rate on the nutrient media, the formation of exudates, soluble pigments and sclerotia, and the thermotolerance were examined. The most important diagnostic characters are the morphological features of the conidial heads, including their growth pattern, size and seriation, dimensions and surface texture of the conidiophore, the shape and size of the metulae, phialides and conidia, and the colour and the wall ornamentation of the phialidospores , reflecting to the apparent genetic variability between different Aspergillus species. Amplicons were sequenced in both directions, sequences were combined and compared with all known related sequences in the databanks, and appropriate phylogenetic trees were constructed. Phylogenetic trees deduced from NJ analyses were drawn , in order to determine their phylogenetic positions  and cox1  the sequences analysed were significantly fewer than above, since there are no other entries in the databanks apart from those examined in our work . The rpb2 and cox1 dataset included 1,140 and 908 characters, with 655 and 303 parsimony informative characters, and produced 20 and 1,185 equally parsimonious trees , respectively. The IGS dataset included 901 characters, with 735 parsimony informative characters . Finally, the rns dataset included 614 characters, with 130 parsimony informative characters .The ITS dataset included 634 characters, 376 of which were parsimony informative, resulting to 10 parsimonious trees : 0.360 and retention index (RI): 0.824). Among the 790 polymorphic sites of the Aspergillus species  and Flavi  presented higher than 90% support for at least two different approaches of bootstrap analyses, whereas sections Clavati, Cremei, Fumigati, and Sparsi clustered with excellent support (>90%) for one methodology and at least good (51–89%) for the other two , A. brunneouniseriatus NRRL 4273 (Cremei), A. aeneus NRRL 4769 (Nidulantes) and A. paradoxus AY373860 (Clavati) formed a mixed cluster . As in the case of the ITS dataset section Nigri was divided into two groups with the second group containing five members . Here again, section Nigri species were placed into two distinct groups with bootstrap support of 100, 100, 99% and 77, 56, 98% , but the two groups were sister clades, supported with 69, 56, and 89% NJ and MP bootstrap and PP values, with the exception of A. japonicus, which was placed basally to rest of the Nigri species. The phylogenies found after the analyses of IGS  and cox1  did not improve the picture drawn from ITS, benA, and rpb2 trees but instead added some ambiguities which could be attributed mainly to the limited number of species examined since this may inhibit the good resolution of the species phylogenetic relationships. Nevertheless, phylogenies from both IGS and cox1 can be used for better distinguishing species within the same section , as also found in a recent paper with other genes by Perrone et al. [rns dataset showed very good clustering of species belonging to sections Aspergillus, Clavati, Circumdati, Nigri, Nidulantes, and Usti  with excellent bootstrap support . Analysis of the same dataset with NJ and BI methods produced similar trees with identical topologies wherever there was a strong support . The secanalyses . In addiCircumdati, clade 1 includes members of section Circumdati with connection to Neopetromyces [Flavi (clade 6), with a recently confirmed connection to Petromyces [Nigri (clade 7) with unknown teleomorphs, even though sclerotia are formed that should be considered as ascomatal primordia [Nidulantes, the sections Nidulantes, and Usti in clade 2 cluster with Emericella teleomorphs that produce ascomata surrounded by Hülle cells. Additionally, few species belonging to subgenus Nidulantes are in clade 3 which forms a cluster intermixed with subgenus Aspergillus sections Aspergillus and Restricti that contain Eurotium teleomorphs with thin layered ascomata loosely suspended in the mycelium. In the subgenus Fumigati, in clade 5, the section Fumigati is connected to Neosartorya with ascomata composed of abundant sterile hyphae and the section Clavati is connected to Neocarpentelles with unilocular stromatic ascomata. Clade 4 includes taxa in sections Terrei, Candidi, and Bispori without evident teleomorphic connections. Most importantly, the tree of the concatenated dataset presented a backbone of seven major clades which could be related to the developmental patterns of the teleomorphs . In the tromyces , a genustromyces , 42, charimordia . In the Aspergillus species [rns and cox1, because the primers designed for these genes can be applied to a wide range of taxonomically different fungi [Aspergillus showed for the first time here that mitochondrial based phylogenies indicate different evolutionary pathways which may provide valuable data for taxonomic purposes when combined with morphological and nuclear based molecular datasets.Fungal phylogeny based solely on morphological criteria or on single genes like the rRNA gene sequences may not always elucidate the taxonomic status of the organisms examined . Also, s species , 15, 45  species , 46, 47. species , 35, 48, species . Currentnt fungi , 51. Ourrns and cox1 from the mt genomes were chosen to study the phylogenetic relationships of Aspergillus species. To overcome possible ambiguities raised by the analyses of these genes, data from the nuclear genes rpb2 and benA that are generally accepted as phylogenetically informative were also used [benA sequences were excluded from the concatenated data used in the most recent multigene approach, since the presence of two or three introns in the corresponding benA amplicons was attributed to amplification of paralogous genes [benA based phylogenetic tree provided additional information as, for example, in the case of members of section Nigri that were clustered together but clearly differentiated the uniseriate from the biseriate species. Thus, all data from nuclear and mt genes were combined as a single unit in order to blend information from two independent heritage lines, to examine whether this approach provides useful information in resolving phylogenetic ambiguities within the genus Aspergillus.It has often been argued that the reconstruction of phylogenies is better achieved by multiple datasets, not only of nuclear but also of mitochondrial origin . In the lso used , 45, 53.us genes , we haverpb2, and rns and, mainly, the concatenated datasets, strengthen the fraternisation of Clavati to subgenus Fumigati, as species of section Clavati form a sister group to species within section Fumigati, with MP bootstrap and PP support that reached 89 and 100%, respectively, at the combined dataset  by NJ-MP bootstrap , and BI Posterior Probability (95%), and thus, altogether may be considered as one group within subgenus Nidulantes , because they either exhibited too high intraspecies variability or this variability was also extended to inter-species comparisons [A. niger species complex but failed to do so for species like A. carbonarius and A. sclerotioniger, or A. japonicus, A. aculeatus and A. uvarum which had identical ITS sequences [cob) gene sequences were informative for many species within the Nigri section but they failed to distinguish between A. niger and A. tubingensis [β-tubulin and calmodulin phylogenetic analysis which placed 26 taxa within subgenus Circumdati section Nigri, further dividing them into 5 main clades, grouping all uniseriate species (7) in only one clade (the A. aculeatus clade) [benA, and rpb2) and the concatenated dataset clearly distinguished members of Nigri and divided them into two groups: the first containing A. aculeatus, A. aculeatinus, A. bahamensis, A. uvarum—in all datasets—and A. homomorphus, A. japonicus—wherever data were available—, and the second composed of all the rest species  with biseriate species belonging to sections Flavipedes, Terrei, Ochraceorosei, and Sparsi, while the uniseriate species of Nigri are basal to the above-mentioned biseriate clades of sections Flavi with good support  , 45. In isolates . The bis 70% PP, . Thus, tFlavi section were grouped well together, with high bootstrap support (>80%), irrelevant to the dataset used. While single gene analysis, like benA, failed to separate A. flavus from A. oryzae, the concatenated dataset clearly demonstrated its advantages. It could fully discriminate all species examined and could also confirm that taxa within the section, like A. oryzae, A. flavus, and A. parasiticus are phylogenetically distantly related to A. ochraceus, as previously proposed [A. flavus, and in extent of section Flavi [Species of the proposed  and alsoon Flavi . Circumdati, Flavi and Nigri do not cluster together [benA, and rpb2 datasets. However, it must be pointed out that this is in contradiction with our morphological observations which demonstrated significant morphological similarities, that is, biseriate conidial heads, large globose vesicles, ascostromata when teleomorph present, and suggest a possible common origin of these sections. The latter is further supported by the analysis of the mt rns sequences, even though the bootstrap values do not seem significant enough. Thus, this intriguing controversy between molecular data and morphological observations underlines the necessity to use polyphasic approaches in one hand and increase the number of species examined on the other in order to solve difficult taxonomy problems.Previous reports showed that sections together  and thisA. niveus and A. terreus, which belong to section Terrei, are closely related and with excellent support (100% irrelevant of the method applied), they are far apart from A. janus (section Flavipedes) and A. arenarius, both of which were previously placed closely to species of Terrei, Flavipedes, and Candidi [A. arenarius as a sister clade to section Flavi with good support  evolutionary lines. Such combined data is expected to provide the appropriate levels of resolving power in future phylogenetic studies.In conclusion, our study clearly shows that all molecules used contributed to the resolution of phylogenetic relationships in Supplemental Figure 1: Phylogenetic tree constructed from unambiguously aligned DNA sequences of the nuclear IGS region as produced by NJ.

From heart disease complicating pregnancy, rheumatic mitral stenosis occupies a larger part. Physiological changes during pregnancy and the impact of pathological mitral stenosis on pregnancy and labor are important to know. A multidisciplinary approach to the diagnosis and treatment reduces mortality and morbidity. We report the case of a patient with mitral stenosis moderately tight with term pregnancy and perioperative management. Pregnancy is a high risk period for women with mitral stenosis (MS). Women of childbearing age met the MS is almost always rheumatic origin. The maternal and perinatal complications during pregnancy in women with unfavorable reflect the interaction between the normal cardiovascular changes of pregnancy and the narrowed mitral valve. We report the case of a pregnant woman at 38 weeks gestation followed wrong with MS moderately tight, admitted intensive care unit.2 cut short axis planimetry, valvular thickening with the large and small mitral valve  to the limit of normal with an ejection fraction 53% left ventricular, pericardium dry, and vena cava inferior to 13 cm in diameter with normal respiratory variation. The results of standard laboratory tests were normal. On the obstetric examination is for a narrows pelvis, after a multidisciplinary discussion cesarean section under spinal anesthesia was determined.A woman aged 26 years, nulliparous, pregnant 38 weeks gestation, with small size 1 meter 50 and a tight mitral stenosis. In this background, we noted repeated episodes of angina, and poor oral health. At admission, she was hemodynamically stable with a blood pressure 120/80 mm Hg, weight 60 kg, had a shallow tachypnea to 23 cycles / minute. On examination, she had dyspnea NYHA Stage II (Classification of the New York Heart Association), bilateral edema of the lower limbs, cardiopulmonary auscultation revealed a rolling end diastolic mitral with intensity 3/6, a burst of B2, tachycardia, and crackles at two discrete lung bases, no evidence for an infringement of the right cavities were observed. The electrocardiogram betrayed bifid P waves, wide (> 0.11 sec) in DI, DII and aVL, in favor of an enlarged left atrium. Echocardiography showed a mitral stenosis moderately tight with an area of 1.3cmal valve , left atPremedication consisted of cimétidine 200 mg, hydroxyzine, antibiotic associated with the imidazole and Beta lactam one hour before induction of anesthesia. The patient has never previously received drugs under heart. Throughout the procedure, blood pressure, oxygen saturation, heart rate, urine output, and ECG were monitored. Spinal anesthesia with 10 mg of isobaric bupivacaine 0.5% with one injection speed very slow under 3 min and nasal oxygen 4 liter/min. Incidents encountered perioperatively were hypotensive episodes, tachycardia and amounted to 96/min, these incidents were just after the installation of the engine block of the two lower limbs were readily reversible after injection titration of ephedrine, extraction of a male baby APGAR score: 10/10 with a weight of 3 kg. The venous thromboembolic disease prevention was established at the tenth hour postoperative: enoxaparin 0.4 ml subcutaneously, multimodal analgesia, diuretics, filling echo guided, and digitalis. The patient transferred on the fourth day in the maternity ward with cardiac monitoring.2 area by planimetry in mode 2 D echocardiography short axis, with little or no MS tight: >1.5cm2, MS moderately tight: 1 to 1.5cm2, MS tight: <1cm2. In our patient we found an area of 1.3cm 2 with a MS moderately tight showing the severity of this disease in association with pregnancy, The MS encountered in women of childbearing age is almost always rheumatic origin. The maternal and perinatal complications during pregnancy in women with MS reflect the unfavorable interaction between the normal cardiovascular changes of pregnancy and MS.The mitral orifice normally is 4 to 5cmIn MS, the valve limit diastolic filling of the left ventricle, which results in a high gradient transmitral and left atrial pressure, and which are further increased by the hyper blood volume and physiological tachycardia during pregnancy, which increases the risk of pulmonary edema. This risk persists and increases during labor and delivery due to uterine contraction, and in connection with the venous return of the lower limbs when the uterus is emptied. The sudden increase in pre-load immediately after delivery, auto transfusion due to the uterus, can flood the central circulation, resulting in a severe pulmonary edema. In addition, there continues to be autologous blood for 24-72 hours after delivery. Thus, this risk extends over several days after birth . Hence tThe objectives of the anesthetic management of patients with MS are: maintaining an acceptable slow heartbeat, immediate treatment of acute atrial fibrillation and a return to sinus rhythm, avoidance of aorto-caval compression, maintenance of adequate venous return, the maintenance of normal blood pressure and preventing pain before it starts, but not forgotten to fight against hypoxia, hypercapnia and acidosis. Antibiotic prophylaxis of endocarditis is reserved only for patients with a history of endocarditis or the presence of established infection . There aAn understanding the physiological changes of pregnancy, mitral stenosis with pathological consequences during the critical period in pregnant women, and especially an adequate perioperative management multidisciplinary between the anesthesiologist cardiologist and obstetrician, converge towards a reduction in mortality and morbidity peripartum.


However, information about the persistence of this association at later ages is limited.Background: The results of previous studies suggest that prenatal exposure to bis[Objectives: We assessed the association of prenatal DDE exposure with child neurodevelopment at 42–60 months of age.Methods: Since 2001 we have been monitoring the neurodevelopment in children who were recruited at birth into a perinatal cohort exposed to DDT, in the state of Morelos, Mexico. We report McCarthy Scales of Children’s Abilities for 203 children at 42, 48, 54, and 60 months of age. Maternal DDE serum levels were available for at least one trimester of pregnancy. The Home Observation for Measurement of the Environment scale and other covariables of interest were also available.Results: After adjustment, a doubling of DDE during the third trimester of pregnancy was associated with statistically significant reductions of –1.37, –0.88, –0.84, and –0.80 points in the general cognitive index, quantitative, verbal, and memory components respectively. The association between prenatal DDE and the quantitative component was weaker at 42 months than at older ages. No significant statistical interactions with sex or breastfeeding were observed.Conclusions: These findings support the hypothesis that prenatal DDE impairs early child neurodevelopment; the potential for adverse effects on development should be considered when using DDT for malaria control. A doubling of serum DDE during the first trimester of pregnancy was associated with a 0.52-point reduction in the Bayley Psychomotor Development Index from 1 to 12 months of age . In a crFrom 1 January 2001 through 30 June 2005, a prospective perinatal cohort study was assembled in Morelos, Mexico. Women were invited to participate during the prenuptial talks required by law for the formalization of civil marriage. Eligibility criteria included no history of chronic diseases , not being treated with anticonvulsant drugs, and not breastfeeding at the time of the baseline interview. Those who agreed to participate in the study were interviewed before they became pregnant to obtain information on sociodemographic characteristics, diet, and reproductive history, and were followed up until they became pregnant. During their pregnancy they were monitored in relation to their pregnancy evolution  and dietary information, and blood samples were drawn in each trimester to measure DDE levels. Each participant signed an informed consent letter. The study was approved by the National Institute of Public Health’s Ethics Committee. Details concerning the cohort-assembling procedures have been published elsewhere .During 8.5 years of follow-up, 442 live first births occurred among the women (80% were primiparous) who had enrolled before their pregnancy . EligibiPostnatal follow-up. Following their birth, the children were assessed at 1, 3, 6, 12, 18, 24, 30, 36, 42, 48, 54, and 60 months of age. During the first visit at 1 month of age, information was obtained about characteristics related to the child’s birth and the beginning of breastfeeding. In each subsequent visit, a structured in-person interview was administered to obtain information about the type and duration of breastfeeding, the child’s dietary habits and health status, and the place where the child was looked after (home or child care center). In addition, the children were weighed and measured for length and head circumference, and their neurodevelopment was assessed. Child neurodevelopment tests varied according to the child’s age, with the Bayley Scale  were obtained during the baseline interview and/or at each trimester visit. After centrifugation, the serum obtained was stored at –70°C in glass vials (prewashed with purified hexane) covered with a Teflon cap, until analyzed.The levels of DDE and DDT in serum were determined by means of gas chromatography with an electron capture detector , following the protocol recommended by the U.S. Environmental Protection Agency (1980). Concentrations of DDE and DDT were determined on a wet basis as nanograms per milliliter (parts per billion), and on a lipid basis as nanograms per gram of lipid. The detection limit was 0.05 ng/mL and 0.0045 ng/mL for DDE and DDT, respectively. All serum samples were above the limit of detection for DDE, whereas an average of 24.1% (depending on the trimester of pregnancy) was above the limit of detection for DDT. Due to the high proportion of samples < LOD for DDT, we report only the association with DDE.p-chorophenyl) ethane  was analyzed, with recovery of 100.8, 100.01, 100.91, 103.4, and 104.1%, respectively. Additionally, one randomly selected sample was analyzed in duplicate in each batch, with a coefficient of variation of 4.4% and 8.3% for DDE and DDT, respectively. The results of the external quality control comparing DDE levels measured in 10 split serum samples by our laboratory (CINVESTAV) and M. Wolff’s laboratory in the Division of Environmental and Occupational Medicine at Mount Sinai Medical School showed a coefficient of Bland–Altman correlation of 0.98.For internal quality control, each of the serum samples was fortified with aldrin and the average recovery was 98.15 ± 8.8%. For every 10 study samples, one sample of bovine serum with known quantities of β-hexachlorocyclohexane (β-HCH), aldrin, hexachlorobenzene (HCB), DDE, and 1,1-dichloro-2,2-bis or chi-square test as appropriate.DDE serum concentrations during each trimester of pregnancy were right-skewed, and were natural logarithm transformed, and Spearman correlations among them across trimesters were calculated. As an indicator of timeliness of DDT exposure, we calculated DDT/DDE ratio dividing DDT on DDE serum concentrations; ratios < 1 suggest a nonrecent DDT exposure. Using mixed-effects models, we estimated the mean of each McCarthy component at 42, 48, 54, and 60 months. This last variable was further coded as 1, 2, 3, or 4 to test for trend.The association between prenatal DDE exposure and child neurodevelopment during 42–60 months of age was estimated through mixed effect multivariate models, for each component of the McCarthy Scale  and separately for each trimester of pregnancy. The models’ general equation is the following:ijY = iDDEβ + iXβ + ijZγi + εij, [1]ijY corresponds to a McCarthy component  in participant i and time j , iDDE is the natural logarithm of DDE serum concentrations during each trimester or its average during pregnancy. Potential adjustment factors with fixed effect (iX) were added one at a time to a crude model: maternal age and education (years), occupation (paid/unpaid), parity (first pregnancy/more than one pregnancy), maternal IQ, mother’s marital status at child’s age of 4 years (in a stable union yes/no), father’s education (finished years), gestational age at birth (weeks of pregnancy), type of birth , child’s sex , birth weight (kilograms), breastfeeding history , attendance at a child care center at 4 years of age (yes/no), HOME scale results at 6 months of age, and blood lead . Only those that changed the crude estimator of interest > 10% remained in the final model. Finally, ijZγi are random effects variables for age and anthropometry for assessment j. A linear random slope of age at evaluation and an unstructured covariance were considered for all models. To check the sensitivity of our estimates to the influence of missing maternal DDE values in any trimester of pregnancy, we repeated the analyses in the subset of children (n = 84) with two or more neurological evaluations, but whose mother had DDE values in all trimester of pregnancy.where 2DDE), to estimate the change in each McCarthy Scales component for a doubling of the serum DDE level.To facilitate the interpretation, the (beta) regression coefficient corresponding to the logarithmic levels of DDE in each trimester of pregnancy was multiplied by 0.69 , we added product interaction terms between DDE (continuous) and each potential modifier to final models (one at a time). Interaction term p < 0.05 was considered significant. All analyses were carried out using STATA software version 12.1 .The normality of the residuals in final models was assessed using the Shapiro–Wilks test, histograms, and quartile graphs. Model predictions were graphed against standardized residuals to assess heteroscedasticity. For all evaluations, Males were more prevalent than females in the study population included in this analysis . About oResults in the McCarthy Scale for all children at each measurement were found to be within the normal limits for each component of the test. In most cases, girls showed higher performance on scale components than boys, with significantly higher scores for perceptual-performance at 42 months and for the GCI, verbal, and memory components at 42 and 48 months. GCI, perceptual-performance, verbal, and motor components showed a statistically significant increase with increasing age among boys, but not girls .p = 0.01). Estimated associations were similar when natural log-transformed DDE was modeled on a lipid-weight basis and when lipid concentration was included as an independent covariable. Blood lead levels, which were available for 84, 77, and 97 mothers in the first, second, and third trimester , did not confound associations between developmental scores and DDE (data not shown).A doubling of serum DDE levels (nanograms per milliliter) in the second and third trimesters was negatively associated with GCI, quantitative, verbal, and memory component scores, though associations were significant for the third trimester only  . DDE wasp-values > 0.10). The HOME scale was a statistically significant positive predictor of all McCarthy test components (data not shown).The association between maternal serum DDE during the third trimester and the quantitative component score varied depending on age at assessment, with a statistically significant interaction at 54 months, compared to 42 months, resulting in a weaker association at 42 months . No signFindings from this study suggest that DDE prenatal exposure has a long-term effect on child neurodevelopment. We observed that a doubling of serum DDE (nanograms per milliliter) during the third trimester of pregnancy was associated with a reduction of –1.37, –0.88, –0.84, and –0.80 points in the GCI, quantitative, verbal, and memory components of McCarthy scale at 3.5–5 years of age.To date, only two additional studies have published results regarding prenatal DDE levels and neurodevelopment in preschoolers, with inconsistent results, probably due to methodological differences. In our cohort, maternal serum DDE level during the first trimester was negatively associated with psychomotor development   during tThe motor component of the McCarthy Scale was not associated with prenatal DDE exposure, consistent with a study of Mexican-American children evaluated using the Bayley Scale at 12 and 24 months of age  and with4), was negatively associated with child neuropsychological functions. In the same study, DDE exposure during pregnancy was also associated with reduced resine triiodothyronine uptake ratios in mothers and children  of about 30%, children were very similar in key parental, infant, and family characteristics independent of the number of missing DDE data values.The high proportion of cesarean sections observed in this study is consistent with a regional survey that reported that Mexico has one of the highest proportions of deliveries by cesarean section in Latin America, with a range of 28–72% depending on the type of health service used  . TherefoThe potential for differential measurement error is low because the psychologists applying the McCarthy Scale had no knowledge of the prenatal exposure of each child. However, random error in the measurement of child neurodevelopment, exposure, or model covariates may have influenced results. In addition, the lack of validation of the McCarthy Scale in the Mexican population may reduce its sensitivity and specificity.There are no published data regarding polychlorinated biphenyls, arsenic, or organophosphate levels in the study area, but there is evidence of lead exposure , so alteA limitation of our study was the lack of information regarding postnatal DDE exposure, which prevented us from assessing the role of this exposure in child neurodevelopment at 3.5–5 years of age. However, lack of effect modification by breastfeeding in the present study suggests that postnatal exposure from this source was not important. We also did not have information on postnatal lead exposure or infant nutrition. However, we believe that prenatal exposure is likely to be more influential than postnatal exposure for the development of the central nervous system.Our findings support the hypothesis that DDE prenatal exposure is negatively associated with child neurodevelopment at 3.5–5 years of age. Additional follow up is needed to determine if GCI, quantitative, verbal, and memory associations with prenatal DDE exposure is a key determinant of poor further academic performance, considering that DDT is still being used in some countries .


Guillain-Barré syndrome is a rare neurological disease of progressive installation, usually following a previous acute infectious state, has a rare incidence, especially in pregnancy, and can induce major complications and high mortality risk. Its occurrence, after immunization to influenza during the last trimester pregnancy, has not been reported before. We presented a case of a 36-year-old pregnant woman that was immunized to H1N1 in the last trimester; 10 days later she developed shoulder and lumbar spine's pain, limbs weakness and facial paralysis with unfavorable clinical evolution and was submitted to intensive therapy care. We described clinical and obstetrical approach, pointing out peculiarities involved in this pathology in pregnancy. Guillain-Barré syndrome (GBS) is an acute inflammatory polyneuropathy demyelinating of autoimmune etiology with incidence ranging from 0,75 to 2 cases per 100.000 people a year [It begins with ascending and progressive weakness of legs and arms and areflexia, evolving from hours to days, lasting three weeks for the whole installation. Paraesthesias and cranial nerves involvement often happen, and bladder dysfunction is found in most serious cases, usually transitory. Around 75% of patients report an acute infection preceding the disease in 1–3 weeks. The GBS association with vaccination to influenza is rare. The incidence is less than a case by 100.000 shots and less than 3% before 20 years old [We report a GBS case after immunization to influenza on pregnancy, in which early diagnosis and therapeutic measures were necessary in order to restore maternal and fetal well being. It presented the importance of clinical propaedeutic and assistance especially in the last trimester of pregnancy and in appropriate management of labor.36-years-old patient, African descendent, gravida 4 para 1, went to São Paulo's Hospital at Paulista School of Medicine , 36-week-gestation, complaining of shoulder and lumbar spine's pain and limbs weakness from the last 20 days. She developed progressive facial paralysis, dysphagia mainly for liquids, dyspnoea, diplopia, and urinary and fecal incontinence. The patient had previously received H1N1 shot 10 days before the onset of symptoms. She was conscious and alert, hemodynamically stable, and with no signs of respiratory distress. Neurological evaluation showed diplopia at right, facial diparetic worse at right, motor strength in degree 4 in upper limb and in degree 3 in lower limb, global areflexia, global hypoesthesia especially distal region of hands and feet, and dysarthric speech. Obstetrical examination showed uterine height adequate to pregnancy period, single fetus, alive, and cephalic presentation. Laboratory investigation excluded infection, and cerebrospinal fluid analysis revealed proteins 114 mg/dL, glucose 76 mg/dL, and 6 leukocytes. She was admitted to intensive care unit and immediately received intravenous immunoglobulin 2 g/kg during the following 5 days, besides obstetrical, psychotherapy, physiotherapy, and speech therapy support.After the first day, there was a clear improvement in dysphagia and of proximal limb strength. On the 4th day the patient was discharged from ICU and received in the obstetric ward to undergo support and finish the treatment. All fetal parameters checked (ultrasonography and cardiotocography) were normal throughout the period of hospitalization. Carbamazepine prescription was used for neuropathic pain. She was discharged on the 14th day, forwarded to risk prenatal care at UNIFESP. On the 21st day, 38-week-gestation was admitted to child-birth unity for spontaneous labor, with uneventful vaginal birth, giving birth to a 2640 g male newborn, Apgar 9 in the first minute and 10 in the fifth minute. No anesthetic procedure was performed. Early postpartum period had good evolution, and only low urinary incontinence was observed, being referred for pelvic floor physiotherapy.Guillain-Barré syndrome is a rare and dangerous neurological disease especially during pregnancy. Its occurrence can be established in 13% in the first trimester, 47% in the second trimester, and 40% in the third trimester .Controlled and randomized studies showed plasmapheresis effectiveness in the GBS treatment; however, its use was related, among other complications, with potential risk of hypotension and septicemia . IntraveAnesthetic procedures are at risk for these patients. General anesthesia carries significant risk of hyperkalemia associated with the use of succinylcholine, and frequent autonomic instability easily was found in these cases. Regional blockage seems to worsen hypoesthesia and neurological syndromes .In this case, an appropriate management of the patient was performed, allowing fast reversal of the situation and favorable outcome of pregnancy. This is the first case of Guillain-Barré syndrome after immunization to H1N1 in the third trimester of pregnancy.Early GBS diagnosis must be done in order to achieve an effective treatment and rather under multidisciplinary care. Prevention of adverse events, proper management of pain, and control of the patient's anxiety are fundamental, even more critical in pregnancy and puerperium.In conclusion, people should clearly understand that the risk of being infected by Guillain-Barré syndrome is much less than the chance of getting influenza, being hospitalized, and dying from flu complications. The vaccine remains effective and necessary for successful public health program.


C. jejuni cases were identified for inclusion. While regional variation exists, distribution estimates indicate that eight serotypes accounted for more than half of all sporadic diarrheal cases globally and three serotypes  were dominant inter-regionally as well as globally. Furthermore, a total of 17 different serotypes reached a representation of 2% or greater in at least one of the five regions sampled. While this review is an important first step in defining CPS distribution, these results make it clear that significant gaps remain in our knowledge. Eliminating these gaps will be critical to future vaccine development efforts.Penner serotyping has been the principal method for differentiating Campylobacter isolates since its inception. Campylobacter capsule polysaccharide (CPS), the principal serodeterminant on which Penner serotyping is based, is presently of interest as a vaccine component. To determine the required valency of an effective CPS-based vaccine, a comprehensive understanding of CPS distribution is needed. Because of the association between Penner serotype and CPS, we conducted a systematic review to estimate the frequency and distribution of Penner serotypes associated with cases of Campylobacteriosis. In total, more than 21,000 sporadic cases of  Campylobacter spp., is often a self-limiting disease commonly associated with diarrhea, cramping, headache, and fever. However, severe cases, including those resulting in dysentery, may require medical attention. Furthermore, long-term sequelae, including Guillain-Barré Syndrome (GBS), reactive arthritis, and irritable bowel syndrome (IBS) have been linked to infection Campylobacter spp. involved in human diarrheal disease are C. jejuni and C. coli. However, for the purpose of this systematic review, analysis will be limited to C. jejuni.Campylobacter is a gram negative organism that belongs to the class epsilonproteobacteria, and is recognized as a major foodborne pathogen in developed and developing countries alike. Campylobacteriosis, the disease caused by C. jejuni have used the Penner serotyping scheme, a passive slide hemaglutination assay developed by Penner and Hennessy C. jejuni does not express LPS, but instead expresses lipooligosaccharides (LOS) and a capsule polysaccharide (CPS) C. jejuni, which mirror CPS variation within the species C. jejuniC. jejuni strain 81–176 (HS23/36) and CG8486 (HS4 complex) conjugated to CRM197 (a diptheria toxin mutant) reduced disease in the intranasal mouse model following challenge with the homologous strain. And, vaccines made with CPS of 81–176 also provided 100% protection against diarrheal disease in Aotus nancymaae, a new world monkey, when challenged with 81–176 For the past 30 years, epidemiologic studies of C. jejuni. A first step in that direction will be determining the prevalence of CPS types circulating globally. Due to the correlation between CPS and Penner types, this review aims to summarize Penner serotyping data of clinical isolates, and by extension C. jejuni CPS type distribution, as reported in the published literature since the advent of Penner’s method.These data suggest that CPS based vaccines are a viable strategy to protect against diarrheal disease. However, continued pursuit of such a strategy will require answering questions about the required valency of a broadly effective CPS conjugate vaccine against C. jejuni infections in which human isolates were typed by the Penner-serotyping method. Research articles that reported data on fewer than ten isolates, data from outbreaks, or data from collections of isolates with evidence of selection bias (i.e. studies examining isolates from Guillain-Barré Syndrome patients only) were excluded. No further exclusionary restrictions were applied, such as the makeup of the study population, the length of the observation period, or the publication date. Disagreements between reviewers concerning inclusion were resolved by consensus. Data from studies selected for inclusion were extracted by two authors independently. The data were extracted according to a fixed protocol to include, the author, year, and location of the study, the demographics of the study population, the serotyping methodology used, the length of the study period, and the number of serotypes screened, and a count of the serotypes identified. Extracted data were entered independently into a Microsoft Access  database. Reported isolates were assigned to 1 of 35 commonly observed serotypes or cross-reactive serotype groups , HS5/31, HS6/7, HS8/17, HS9, HS10, HS11, HS12, HS15, HS18, HS19, HS21, HS22, HS23/36, HS27, HS29, HS32, HS33, HS35, HS37, HS38, HS40, HS41, HS42, HS45, HS52, HS53, HS55, HS57, HS58, HS60, HS62, or Non-Typable). Some Penner serotypes were reported as belonging to more than one of the HS types indicated above, and such isolates were distributed across each serotype indicated. For example, an isolate reported as belonging to serotype HS24/55/60 would be distributed equally as HS24 = 0.33, HS55 = 0.33, and HS60 = 0.33. Several research articles also grouped a fraction of isolates into the non-descript category “Other”, when the relative proportion of a given serotype was below a reporting threshold determined by study authors. In these instances, the serotypes of the “Other” isolates were imputed across each study and distributed in the relative global proportions calculated for the 35 C. jejuni serotypes outlined above. C. coli serotypes, when reported, were not included in this analysis. Discrepancies concerning serotype assignment were resolved through discussion amongst all study authors. Serotypes were tallied within each study, and their respective proportions were calculated. Pooled proportional estimates were computed across all studies and within studies grouped by region. The proportional estimates were computed using the DerSimonian & Laird random effects model Relevant published data were identified from searches of PubMed for research articles containing the keyword “Campylobacter” and the term “Penner” or “serotype”. At the same time, non-English publications, and review articles were excluded. The titles and abstracts of the identified articles were screened for relevance and evaluated independently by two of the study authors for inclusion on the basis of the availability of the article, and whether or not the article had previously unpublished, extractable data. Inclusion was limited to studies of natural sporadic A search of the PubMed database identified 596 research articles for possible inclusion. After removing the duplicates, 488 research articles remained for consideration. A review of the titles and abstracts excluded another 410 articles from consideration based on relevance to the topic of interest, leaving 78 studies to be assessed for eligibility for inclusion. The full text of each of the 78 articles was examined in more detail, and data from 54 studies were included for the purpose of this review. Five publications reported stratified data that are included as separate studies for the purpose of this review, bringing the total number of studies to 59 See .C. jejuni isolates from sporadic cases of enteric infection collected between 1978 to 2008 from 29 different countries (C. coli)  See .Overall, the studies predominately sampled European populations. Nearly 85%  of the isolates included in this analysis were from Europe, while 1,186 were from Asia, 763 were from North America, 695 were from the Oceanic Region, and 566 were from Africa . No studGlobally, eight serotypes  accounted for 50.4% of all isolates. The dominant serotypes were those of the HS4 complex , HS2 , and HS1/44  See . CombineC. jejuni is known to be phase variable Beyond the three most dominant serotypes, in all, 17 different serotypes reached a proportional representation of 2% or more in at least one of the five geographic regions considered . Nine seC. jejuni serotypes both globally and by geographic region. Estimates were derived from 59 published studies on more than 21,000 cases of sporadic diarrhea. Based on these estimates, eight serotypes account for half of all isolates globally and three serotypes in particular , were consistently represented across all regions.Since Penner first introduced the method C. jejuni infections, it is not without limitations. In fact, the estimates presented here are almost certainly imprecise. Data are sparse in every region of the world. No studies reporting extractable data were identified in South America and relatively few studies reported data from Africa and Asia, regions in which enteric infections contribute significantly to morbidity and mortality. The fact that some geographic regions are underrepresented may be partially due to the exclusion of non-English publications. However, the lack of data most probably reflects an absence of surveillance in these regions. With limited data from every region of the world, save Europe, the global estimates presented are biased towards those calculated in Europe. Even in Europe, from which 85% of the isolates in this study originated, there are insufficient data to draw conclusions regarding temporal changes in serotype distribution, geographic variation, and differences across demographic groups . The estimates presented here are also based on reports of sporadic cases of diarrhea. If an association between serotype and disease severity exists, selection bias has the potential to overestimate serotypes that result in manifest symptoms. Additionally, although a modest number of publications included in this review used a commercially available kit consisting of 25 antisera , most studies relied upon custom reagents generated in-house or from another laboratory. The lack of standardized reagents calls into question the comparability of results across individual studies. Similarly, studies varied from one to the next with regards to which and how many serotypes were tested. These methodological differences undoubtedly influenced the estimates calculated here. Studies that did not screen a complete panel of antisera capable of detecting every serotype risked under-reporting certain serotypes, classifying them instead as non-typable. Finally, because C. jejuni is known to be subject to phase variation, assays such as Penner serotyping that depend upon the expression of CPS have the potential to underestimate the prevalence of any given Campylobacter serotype.Although this study is the first of its kind and a significant step forward in understanding the serotype distribution of C. jejuni serotyping, its use has been declining in recent years and, today, the technique is routinely performed by only a small number of reference laboratories in North American and Europe. The limited and declining use of Penner typing is due in part to the complexity and cost of generating polyclonal rabbit sera to the 47 C. jejuni type strains, as well as to the emergence and value of other typing schemes such as Multi Locus Sequence Typing (MLST) and the ever-decreasing cost of direct sequencing. For a surveillance system to be implemented that is sufficiently large enough to address the outstanding questions of CPS distribution and disease association, alternative methodologies for determining the CPS type of C. jejuni isolates will almost certainly need to be employed. Such alternative methodologies will need to be cost-effective, efficient with respect to time, readily transferred to most any laboratory, and have high throughput capacity. Recently, our group offered a method that meets these criteria. Sequencing has revealed that each Penner serotype is unique with regards to the genomic structure of the cassette of genes involved in the biosynthesis of the serodeterminant CPS If current efforts to develop a CPS-based vaccine are to succeed, robust surveillance systems are needed to address substantial gaps in knowledge surrounding the geographic distribution and temporal stability of serotypes. Future surveillance methods should also aim to reveal demographic differences in serotype distribution  and disease/serotype associations . Combined with investigations into the immunogenic properties of the differing CPS types, addressing these fundamental surveillance-related questions will be important in determining the composition of a future vaccine with regards to valency. Furthermore, the need for surveillance is greatest in developing regions, where diarrheal disease is most prevalent and available data are lacking. Diarrheal episodes amongst children in the developing world are believed to cause millions of deaths annually Figure S1Flow diagram of articles search, reviewed, and included in the systematic review.(DOCX)Click here for additional data file.


Diabetes is a serious health problem and a source of risk for numerous severe complications such as obesity and hypertension. Treatment of diabetes and its related diseases can be achieved by inhibiting key digestive enzymes related to starch and lipid digestion. The findings revealed that the administration of trigonelline to surviving diabetic rats helped to protect the pancreas β-cells from death and damage. Additionally, the supplement of trigonelline to surviving diabetic rats significantly decreased intestinal α-amylase and maltase by 36 and 52%, respectively, which led to a significant decrease in the blood glucose rate by 46%. Moreover, the administration of trigonelline to surviving diabetic rats potentially inhibited key enzymes of lipid metabolism and absorption such as lipase activity in the small intestine by 56%, which led to a notable decrease in serum triglyceride (TG) and total cholesterol (TC) rates and an increase in the HDL cholesterol level. This treatment also improved glucose, maltase, starch, and lipid oral tolerance. Trigonelline was also observed to protect the liver-kidney functions efficiently, which was evidenced by the significant decrease in the serum aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyl transpeptidase (GGT), and lactate dehydrogenase (LDH) activities and creatinine, albumin, and urea rates. The histological analysis of the pancreas, liver, and kidney tissues further established the positive effect of trigonelline. Overall, the findings presented in this study demonstrate that the administration of trigonelline to diabetic rats can make it a potentially strong candidate for industrial application as a pharmacological agent for the treatment of hyperglycemia, hyperlipidemia, and liver-kidney dysfunctions. There aet al. , 10, whii.e.; α-amylase and maltase in the intestine [Diabetes mellitus, with its attendant complications and related diseases, constitutes one of the most serious, costly, and fast-growing health problems in the twenty-first century. One of the therapeutic approaches proposed so far for the decrease of drug-treated diabetes is based on the retardation of glucose absorption through the inhibition of carbohydrate-hydrolyzing enzymes, ntestine .al[The results revealed that diabetes induced a considerable increase in the α-amylase, and maltase activities in the mucosal small intestine by 204 and 290% respectively, which led to an increase of the glucose rate by 236% in the serum of diabetic rats. However, in trigonelline -treated diabetic rats, the activities of those enzymes underwent considerable improvements. In fact, the administration of trigonelline to surviving diabetic rats significantly reduced the activities of all of those enzymes in the intestine of surviving diabetic rats. The inhibitory effect on intestinal α-amylase and maltase activities significantly decreased the glucose concentration in the serum . In factal reportedal[al), have rin vivo inhibitory effects on the key enzymes of lipid digestion and absorption such as lipase in the small intestine, which contributes therapeutic action against hyperlipidemia, obesity, and heart diseases [The findings of the present study also demonstrated that diabetes increased lipase activity in the intestine and that the increased lipid absorption from the intestine consequently amplified the hypercholesterolemia and hyperlipidemia in the serum. The administration of trigonelline to surviving diabetic rats also exerted diseases . In factThis study indicated in This study was performed by an oral lipid tolerance test and was performed in all rats at the end of this treatment. Rats were fasted for 12 h before the test and serum samples were taken from the tail vein for the determination of TG levels. Then, an oral oil challenge (2 g/kg body weight) was given by gavage and serum samples were taken at 3, 6, 9, and 12 hours after oil administration. The serum TG level was increased after 3 and 6 h oral administration of the trigonelline, this being followed by a decrease 6 h after the administration, with its effect being the strongest at 9 h after the oil gavage. These results are in agreement with previous studies reported that fenugreek trigonelline decreased the elevated lipids TC, TG, LDL-C, and increased the decreased HDL-C .As far as the liver of diabetic rats is concerned, the present study showed an increase in terms of the AST, ALT, LDH, and GGT activities by 88, 83, 63, and 44%, respectively, in serum . InteresMoreover, the table evidenced that the administration of the trigonelline to surviving diabetic rats seems to have reverted back this increase of serum creatinine and urea, with a significant decrease in albumin as compared to untreated diabetic rats. The positive effect was confirmed by histological findings. In fact, in In conclusion, the present study has demonstrated that trigonelline significantly improved glucose and lipid homeostasis in diabetes by delaying carbohydrate and lipid digestion and absorption, and enhancing or mimicking insulin action. Therefore, trigonelline represents a potentially useful dietary adjunct for the treatment of diabetes, obesity, and a potential source for the discovery of new orally active antidiabetic agents)Wistar rats, weighing 153 ± 12 g, which were obtained from the local Central Pharmacy, Tunisia.

One week later, the blood glucose concentration was measured, and the value was two-fold higher than that in the control rats. The serum glucose level of the rats was measured by the glucose-oxidase reaction using commercially available kits from Biomagreb Tunis, Tunisia. On the day the experiments started, and before treatment, the rats were divided into eight groups of eight animals each as follows:One month later, the rats were weighed and sacrificed by decapitation, and their trunk blood was collected.

Objectives. To investigate the effectiveness of extracorporeal shock wave therapy (ESWT) for symptoms alleviation in chronic pelvic pain syndrome (CPPS). Materials and Methods. 40 patients with CPPS were randomly allocated into either the treatment or sham group. In the first group, patients were treated by ESWT once a week for 4 weeks by a defined protocol. In the sham group, the same protocol was applied but with the probe being turned off. The follow-up assessments were done at 1, 2, 3, and 12 weeks by Visual Analogue Scale (VAS) for pain and NIH-developed Chronic Prostatitis Symptom Index (NIH-CPSI). Results. Pain domain scores at follow-up points in both treatment and sham groups were reduced, more so in the treatment group, which were significant at weeks 2, 3, and 12. Urinary scores became significantly different at weeks 3 and 12. Also, quality of life (QOL) and total NIH-CPSI scores at all four follow-up time points reduced more significantly in the treatment group as compared to the sham group. Noticeably, at week 12 a slight deterioration in all variables was observed compared to the first 3 weeks of the treatment period. Conclusions. our findings confirmed ESWT therapy as a safe and effective method in CPPS in short term. Chronic pelvic pain syndrome (CPPS) is a frequent outpatient urological diagnosis . The incα-receptor blockers, and 5α-reductase inhibitors have been used as single or combination therapy with variable success rates [The pathophysiology of CPPS has not yet been completely explained. Psychiatric and somatic factors possibly play roles; however, no infection or bacterial pathogen has been detected yet . Moreovess rates , 16, 17.There are also some alternative therapies that have been introduced such as physiotherapy, trigger-point massage, electromagnetic treatment, acupuncture, rectal massage, hyperthermia, thermotherapy, balloon dilatation, laser coagulation, invasive neuromodulation, and intraprostatic injection of botulinum toxin A , 19. NonRecently, effectiveness of perineal extracorporeal shock wave therapy (ESWT) has been investigated in CPPS patients , 20, 21.In this study we conducted a randomized sham-controlled trial to evaluate the efficacy of ESWT on CPPS.From October 2011 to October 2012, all patients with chronic prostatitis type IIIB/chronic pelvic pain syndrome according to NIH International Prostatitis Collaboration Network reports  who wereBacterial prostatitis was ruled out by a 2-glass test. In this test a midstream urine sample was collected with the 10 CC of urine being discarded and the second 10 CC collected and then prostate massage was done for a minute by digital rectal exam and then another 10 cc of urine was collected. These samples were analysed and cultured.2 and 3 Hertz of frequency were delivered, although 0.5 mJouls/mm2 was added in each week . After each 500 pulses, the probe position was corrected, using transperineal ultrasound. In this study we used the standard electromagnetic DUOLITH SD1, Storz Medical, Tägerwilen, Switzerland. The treatment was performed in supine position.The study protocol was approved by the Ethics Committee of Isfahan University of Medical Sciences. After patient consultation about the method and obtaining written consent, they were allocated into either the treatment or sham group with simple randomization. In the first group, patients were treated by ESWT once a week for 4 weeks. Each time 3000 impulses, with 0.25 mJouls/mmIn the sham group, the same protocol was applied but with the probe being turned off.The follow-up assessments were done at 1, 2, 3, and 12 weeks following the first ESWT session. For each patient, pelvic pain intensity was measured at the beginning of each follow-up episode, using Visual Analogue Scale . In addition, NIH-developed Chronic Prostatitis Symptom Index (NIH-CPSI) was filled at the beginning of each follow-up visit. Finally, obtained data were recorded in special profile for each patient and analysed.t-test, Wilcoxon, and, as necessary, repeated ANOVA were used.Data were entered in SPSS (version 18). The statistical analyses such as chi-square, independent The mean ages of the patients in the treatment and sham groups were 35.4 ± 8.4 and 37 ± 10.1 years, respectively. At baseline, the means of pain score, urinary score, QOL, and NIH-CPSI score between the two groups were not statistically different . Pain doIt should be noticed that in all four domains, as well as the pain score, some deterioration was observed at week 12 compared to week 3 of followup . RepeateNone of the patients experienced perineal pain or voiding difficulty during the follow-up period.Totally, results in Our study showed that total NIH-CPSI, pain and urinary symptom scores, and QOL improved significantly in ESWT group compared to sham group, although we observed some deterioration in all fields at week 12 of follow up compared with week 3.In recent years, a few studies have evaluated the efficacy of ESWT on CPPS. Zimmermann et al. in their first study  showed sLater, Zimmermann et al. reported a similar trial  that incYan et al.  in theirOne important issue is the exacerbation of NIH-CPSI, pain, and symptom scores on week 12 followup in both groups that may challenge the persistence of therapeutic effect of ESWT therapy. In previous surveys the outcomes showed only progress in their trend on followup, which is not in accordance with our results. Therefore, more comprehensive research with long-term followup may clarify this ambiguous point.The pathogenesis of the CPPS is not completely understood. Proposed mechanisms include infection leading to pain via nociceptive nerve endings and receptors, pelvic floor hyperactivity, local chemical alterations, neurologic components, and perfusion disturbances , 12, 13.Numerous studies in orthopaedics, urology, and cardiology have shown ESWT to have low side effects , 27, 29.2 was added in each week. Patients showed improvement in their symptoms in week 3 compared to week 2; however this improvement did not continue until week 12 and consequently no definitive conclusion could be drawn regarding the long-term effect of this study protocol. One of the shortcomings of our study is that we did not evaluate the IPSS score and erectile function in our patients. The effectiveness of different treatment intervals and frequencies must be investigated further to define optimum treatment regimens for ESWT effects.ESWT effect can be considered dose dependent , 30. In In conclusion, our findings confirmed ESWT to be a safe and effective therapy for CPPS in the short term. Nevertheless, more comprehensive surveys so as to describe a standard protocol for ESWT, with long-term followups, are essential.
