Fungi are highly important biotic components of terrestrial ecosystems,but we still have a very limited understanding about their diversity and distribution.This data article releases a global soil fungal dataset of the Global Soil Mycobiome consortium(GSMc)to boost further research in fungal diversity,biogeography and macroecology.The dataset comprises 722,682 fungal operational taxonomic units(OTUs)derived from PacBio sequencing of full-length ITS and 18S-V9 variable regions from 3200 plots in 108 countries on all continents.The plots are supplied with geographical and edaphic metadata.The OTUs are taxonomically and functionally assigned to guilds and other functional groups.The entire dataset has been corrected by excluding chimeras,index-switch artefacts and potential contamination.The dataset is more inclusive in terms of geographical breadth and phylogenetic diversity of fungi than previously published data.The GSMc dataset is available over the PlutoF repository.

The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies.Over the past decades,rapid development and affordability of molecular tools have tremendously improved insights of the fungal diversity in all ecosystems and habitats.Yet,in spite of the progress of molecular methods,knowledge about functional properties of the fungal taxa is vague and interpretation of environmental studies in an ecologically meaningful manner remains challenging.In order to facilitate functional assignments and ecological interpretation of environmental studies we introduce a user friendly traits and character database FungalTraits operating at genus and species hypothesis levels.Combining the information from previous efforts such as FUNGuild and FunFun together with involvement of expert knowledge,we reannotated 10,210 and 151 fungal and Stramenopila genera,respectively.This resulted in a stand-alone spreadsheet dataset covering 17 lifestyle related traits of fungal and Stramenopila genera,designed for rapid functional assignments of environmental stud-ies.In order to assign the trait states to fungal species hypotheses,the scientific community of experts manually categorised and assigned available trait information to 697,413 fungal ITS sequences.On the basis of those sequences we were able to summarise trait and host information into 92,623 fungal species hypotheses at 1%dissimilarity threshold.

Recent studies have revealed concerning declines in bird populations in Europe and other parts of the world.In understudied but biodiverse regions,especially those that are located along key migratory flyways,there is an unmet need to evaluate the status of resident and migratory birdlife for avian conservation ecology.This is especially urgent at a time when recent regional studies have highlighted the scale of the decline of the European and Palearctic avifauna.Rapidly growing community science datasets may help bridge the gaps in our understanding of long-term regional avifaunal trends.In this study,we used eBird data submitted by observers in Türkiye to undertake the first long-term assessment of the state of the country’s birds from 2001 to 2022.We evaluated population trends based on presence-absence data of species to determine if any birds have significantly increased or decreased in the country so far this century.We provide a list of trends for 418 bird species that had large enough sample sizes of eBird observations from Türkiye,and highlight which species have significantly declined or increased.We found that 63 species have significantly declined in detection while 120 have significantly increased during the study period.Our findings provide a baseline for the future monitoring of Türkiye’s birds and help contextualize population changes of birds in Türkiye against those occurring at the continental(Palearctic)scale.Additionally,we include movement classifications for all of the bird species in this study.We also provide a framework to effectively use eBird data to assess long-term avifaunal changes at the country-level in other understudied regions.Finally,we highlight ways in which eBirders in Türkiye and elsewhere can strengthen the quality and value of community ornithology data for population assessments and avian conservation ecology.

Asian Pacific Journal of Tropical Medicine 2010年第1期3卷 63-65页

作者： Ekabua JE agan TU Iklaki CU Ekanew EI Department of Obstetrics and Gynaecology College of Medical Sciences ScienceUniversity of Calabar

Objective:To investigate the aetiology of abnormal vaginal discharge,using a non-culture based method,among pregnant women presenting at the University of Calabar Teaching Hospital, Calabar,Nigeria.Methods:Two hundred consecutive antenatal patients,aged 18 to 38 years,with complaints of abnormal vaginal discharge between 1st April and 31st July 2004 were investigated clinically for the characteristics of the vaginal discharge.High vaginal swabs taken from the vaginal fornices were examined using a non-culture based method to determine the possible aetiology of the discharge.The possibility of integrating non-culture based laboratory methods in the syndromic case management of abnormal vaginal discharge in an antenatal clinic setting is discussed.Results: The commonest form of abnormal discharge was curdy white in 66%of cases.Ten(5%) women had malodourous vaginal discharged,92%had vulval itching;and superficial dyspareunia was seen in 29%of cases.Microscopic studies of vaginal discharge revealed the following findings: lactobacilli(96%),polymorphs(96%),’clue’ cells(4%);positive Whiff test(5%),and pH > 4.5 (7%).The clinical and laboratory assessment of each patient lasted between 35 and 45 minutes.The procedures used were acceptable to 78%of women.Conclusion:The use of non-culture based laboratory methods in the initial assessment of abnormal vaginal discharge can be a useful adjunct in the syndromic case management of abnormal vaginal discharge in pregnant women.

Objective:To assess the prevalence of anemia and asymptomatia malaria parasitemia and the effect of prior antimalarials therapy on the parasite density in pregnant women at their first antenatal visit at the secondary level health care facility in Nigeria.Methods:This cross sectional observational study was carried out in the antenatal clinic of General Hospital,Ikot Ekpene,Akwa Ibom State,Nigeria for 3 months period(1st June to 31st August,2009).Five hundred and fourteen women attending their first antenatal registration visits in the hospital were recruited in the study.Socio-demographic information was obtained using pre-tested questionnaires.The malaria parasite was obtained by examining thick and thin blood films prepared on 2 glass slides while the hematocrit was obtained through 2 capillary tubes read by a Hawksleys microhematocrit reader.Results:A total of 514 pregnant women participated in the study with a mean maternal age of 21.4 years and a mean gestational age at booking of 18.3 weeks.The primigravid women booked at significantly lower gestational age than multigravidae （16.2 weeks vs 21.6 weeks）.Most of the women（59.3%） were anemic,out of which 60.4%were primigravida.More than half of the women had moderate to high parasite density and only 6.8% had no malaria parasitemia.All patients with severe anemia were parasitemic.Out of the 479 （93.2%） women with parasitemia,a third had taken antimalarial drugs.A majority（60.3%） of those without prior antimalarial drugs had moderate to high density parasitemia.Conclusions: This study shows high prevalence of anemia in women with asymptomatic malarial parasitemia, particularly the primigravida.The severity of anemia is directly related to the density of malaria parasitemia.Those with effective antimalarial therapy appear to have low density parasitemia and therefore mild anemia.Routine screening for anemia and malaria parasites at booking,prompt parasite clearance and correction of anemia would reduce the associated maternal and perinatal

作者： agan TU Ekabua JE Iklaki CU Oyo-Ita A Ibanga I Department of Obstetrics & Gynaecology College of Medical SciencesUniversity of Calabar Department of Community Medicine College of Medical SciencesUniversity of Calabar Department of Haematology College of Medical SciencesUniversity of Calabar

Objective:To evaluate factors associated with prevalence of malaria parasitaemia at first antenatal care visit.Methods:The study was conducted at the University of Calabar Teaching Hospital from 1st June,2007 to 31st July,2007.A structured questionnaire was administered to a total of 545 pregnant women that were recruited in this study after obtaining informed consent and two slides of thin and thick films were prepared for each participant.Results:Five hundred and twenty(95.4%) out of the 545 participants suffered from malaria parasitaemia,the rest 4.6%of those who had no parasitaemia had experienced symptomatic malaria before and were treated in private hospitals prior to their recruitment into the study.All participants(100%) who did not have antimalarials had parasitaemia compared with 91.1%among those that had antimalarials.The proportion of moderate to severe parasitaemia was also significantly higher among the former.Besides,the difference in parasitaemia between primigravidae and multigravidae was statistically significant(P=0.000) too. Among the methods used for vector control,only insecticide treated nets(ITNS) was associated with significant reduction in the level of parasitaemia(RR=0.83).Conclusion:Malaria parasitaemia at first booking is significandy higher in primigravidae and women who have no anti-malaria treatment. The use of safe and effective antimalarial treatment along with ITNs will significandy reduce the level of parasitaemia in pregnant women.

Eosinophilic esophagitis is an inflammatory condition of esophagus.It is generally seen in childhood and young population.Men are more commonly affected than women.However,it is not common in an advanced age.Eosinophilic esophagitis decreases the ability of the esophagus to stretch and accommodation against foods.Therefore,the major symptom in adults with eosinophilic esophagitis is difficulty in swallowing solid food(dysphagia).Specifically,the food gets stuck in the esophagus after it is swallowed.Less common symptoms include heartburn and chest pain.Because of this,it may be incorrectly diagnosed as a gastroesophageal reflux disease.Here,we reported a case presented with food impaction at advanced age.As a conclusion,eosinophilic esophagitis is a rare entity that must be remembered in advance aged patients presenting with food impaction.

作者： Ekabua JE agan TU Iklaki CU Ekabua KJ Etokidem AJ Department of Obstetrics & Gynaecology Department of Community Medicine University of Calabar Teaching Hospital Calabar

Objective: To determine the risk of adverse maternal outcome associated with obstetric intervention in labour.Methods:All cases of macrosomic births conducted at the University of Calabar Teaching Hospital,Calabar,between January 1st 1994 and December 31st 2000 were reviewed.Measure of treatment/intervention effect was calculated as relative risk for adverse maternal outcome,using spontaneous vaginal births as control.Results:Frequency of mode of delivery was as follow: vaginal births,139(60.7%);instrumental vaginal deliveries,16(7%);and abdominal deliveries,74(32.3%).Obstetric intervention occurred in 90(39.3%) cases.Sixty-four(28%) cases did not book for antenatal care,with 42 cases(18.3%) requiring obstetric intervention.About one in every two parturients(1: 2.1) in this study,requiring obstetric intervention at delivery had been interfered with at unorthodox health facilities.Relative risks for postpartum haemorrhage,wound sepsis and paralytic ileus were significantly high in parturients with abdominal delivery;while in parturients with instrumental vaginal delivery relative risks were significantly high for puerperal sepsis,paralytic ileus and obstetric palsy.There were no maternal deaths.Conclusion:Obstetric intervention in parturients with macrosomic births was high due to labour complications;and was associated with significant risk for adverse maternal outcome,especially in parturients with unskilled interference.

海南医学院学报 2010年第1期16卷 28-32页

作者： Omotoso AJ agan TU Bassey IE Ebughe GA Ekanem IA Ekanem AD Department of Pathology Obstetrics and Gynaecology University of Calabar Teaching Hospital

Objective: To assess the prevalence of cervical cancer and histologic variants as seen in Calabar,Cross River state.Methods: This is a retrospective study involving histologically verified uterine cervix carcinoma between January,1997 and December,2006.Results: There were 1,207 malignancies diagnosed during the study period;175(14.5%) were malignancies of the genital tract while 113(9.4.0%) were carcinoma of the cervix constituting 64.6% of female genital malignancies.Cervical cancer was commonest between the ages of 40-59 years.There was no patient with carcinoma of the cervix below the age of 20 years.Squamous cell carcinoma(87.6%) of the uterine cervix was the main histological type.Conclusion:Cervical cancer is still the most common female genital tract malignancy in Calabar with most of these patients in their middle age.The use of PAS/Alcian blue stain as was used in this study eliminates most false-positive squamous cell carcinomas compared with Haematoxylin and Eosin stains used in most reports from most centres in this part of the world.Epithelial malignancies continue to be the predominant histological variant with squamous cell variety the commonest.There is also an urgent need for introduction of efficient and affordable population based cervical screening programme for early detection,use of vaccines against Human Papilloma Virus(HPV) and treatment of pre-malignant cervical lesions.
