Recovery of dried samples from the Helminthological Collection of the Oswaldo Cruz Institute (CHIOC)/Fiocruz through specimen rehydration technique.

The Helminthological Collection of the Oswaldo Cruz Institute is the biggest in Latin America and it is among the largest collections at worldwide reference level, with around 40,000 sets of specimens and approximately one million individual specimens. It contains helminths parasites of vertebrate and invertebrate animals that form part of the fauna of Brazil and other countries. The samples comprise holotypes, paratypes and representative specimens of Platyhelminthes, Acanthocephala, Nematoda and other non-helminth phyla, such as Annelida and Arthropoda. Some of the samples preserved in liquid media were found to have dried out. This made it impossible to analyze these samples morphologically for taxonomic purposes. The aim of this study was to test techniques used for rehydration of the tegument of specimens that had been found to have dried out and present protocols for such techniques. A total of 528 specimens that either no longer were immersed in preservatives or had already dried out were analyzed: 96 digenetic trematodes, 45 cestodes, 22 acanthocephalans, 357 nematodes, four hirudineans and four pentastomid crustaceans. The technique of rehydration using only distilled water on the specimens proved to be efficient for recovering tegument malleability, for all samples analyzed in this present study.

Hemiurid and lecithasterid digenean trematodes and camallanid and cucullanid nematodes parasitizing flounders collected off the coast of Rio de Janeiro State, Brazil.

A total of 132 flounder specimens (60 Paralichthys isosceles, 36 Paralichthys patagonicus and 36 Xystreurys rasile) were collected off the coast of the state of Rio de Janeiro, Brazil. The fish were measured, necropsied, and had their organs investigated for hemiurid and lecithasterid digenean trematodes and camallanid and cucullanid nematodes. Taxonomic identification of the parasites was based on morphological and morphometric characters and was conducted using bright-field and scanning electron microscopies. The trematodes Lecithochirium monticellii and Aponurus laguncula were found parasitizing P. isosceles, P. patagonicus and X. rasile while the nematodes Procamallanus (Spirocamallanus) halitrophus and Cucullanus bonaerensis were found parasitizing P. isosceles and X. rasile and P. isosceles, P. patagonicus and X. rasile, respectively. Parasite indices of prevalence, mean intensity, mean abundance, and range of infection, as well as infection site, were evaluated for each parasite species. This study allowed to evidence the first occurrence of P. patagonicus by L. monticellii; X. rasile by A. laguncula and P. (S.) halitrophus; and P. isosceles and P. patagonicus by C. bonaerensis in the Western South Atlantic Ocean.

Seroprevalence and Efficacy of Prevention of Parent to Child Transmission Program Over a Decade in a Tertiary Care Hospital in Mumbai, Maharashtra.

BACKGROUND: Parent to child transmission is the major mode of spread of HIV. An effective national health program (PPTCT) has been designed under NACO which helps in reducing the spread of HIV by vertical transmission and improving the life of the women and her baby. METHODS: A retrospective study was done at a tertiary care hospital, including pregnant women registered and delivered, and those who came directly in labour at the hospital during a period of 10 years from January 2010 to December 2019. Pretest counselling, HIV testing, Post-test counselling were done, and antiretroviral prophylaxis was given as per the NACP guidelines. Sociodemographic characteristics, obstetric outcome and efficacy of PPTCT services were analysed. RESULTS: Out of the 63,947 antenatal mothers included, 61,061 (95.4%) accepted HIV testing. 177 of these tested positive (0.289%) with a significant reduction in the seroprevalence over the decade. Majority of seropositive women were primigravida; housewives from urban areas, from low income and educational background and with no history of any contraceptive use. Out of 718 live births, the MTCT rate was found to be 4.5% at 6 weeks over the whole decade and was noted to be 1.8 % at 18 months which is well within the goal of PPTCT program and hence elucidating the success. Seventy-four spouses of the 177 seropositive women tested positive, 55 tested negative and 49 did not undergo the HIV testing. Decline in the number of partners not undergoing testing was elicited. The discordant couple rate in the study was 31% and showed variable trend over the decade. CONCLUSIONS: Our study has observed an overall increase in efficacy of PPTCT in terms of increased utilization of PPTCT through the decade, decrease in the vertical transmission and seroprevalence rate, increase in the acceptance rates of HIV testing by partner almost conquering the goal of NACO.

OBJECTIVE: To develop and validate a terminological subset of the International Classification for Nursing Practice for COVID-19 patients in critical care. METHOD: This is a methodological study, which followed the guidelines of the Brazilian method, using the Basic Human Needs as a theoretical model. Content validation was performed by 25 specialist nurses using the Delphi technique. RESULTS: A total of 73 diagnoses and their respective nursing results were prepared. Of these, 62 statements had a Content Validity Index ≥ 0.80, with the need for oxygenation having the highest number of statements. Of the 210 nursing interventions developed, and after suggestions from experts, 150 interventions reached an index ≥ 0.80 and comprised the terminological subset. CONCLUSION: The terminological subset developed showed statements that were validated by specialist nurses and, therefore, are relevant to the nurse's clinic in the critical care scenario associated with Covid-19.

To Study the Maternal and Neonatal Outcome in Postdated Women Undergoing Induction of Labour Versus Spontaneous Labour.

INTRODUCTION: Ensuring safety of the mother along with the delivery of a healthy baby is the ultimate objective of all obstetricians. Labour induction is increasingly becoming one of the most common obstetric interventions in India. The aim of the study is to compare the feto-maternal outcome of induction of labour versus spontaneous labour in postdated women. METHOD: This was a prospective observational comparative study. A total of 100 patients were selected, 50 who had induction of labour (study group) and 50 who had spontaneous labour (control). A structured proforma and partographs were used to obtain data. RESULT: 42% nulliparous women had induction of labour as compared to 29% multiparous women. The rate of cesarean section (58%) was substantially higher in those who had been induced. Non-progression of labour or failure of induction was the commonest indication for cesarean section. Post-partum haemorrhage was a complication found more commonly in the study group. Perineal tears were found more commonly in the control group.The mean birth weight of babies born to mothers who had been induced was significantly higher than that of those born to women who went into spontaneous labour. The APGAR scores were comparable in both groups. There was a higher incidence of hyperbilirubinemia in the study group. CONCLUSION: Although induction of labour is a relatively safe procedure, some foetal and maternal risks were found to be higher in induced group than in those with spontaneous labour. Induction must be carried out only when necessary and not as a routine elective procedure.

O objetivo deste estudo é investigar a experiência da pandemia da COVID-19 no município de Natal ­ RN, considerando a faixa etária dos pacientes acometidos pela doença e suas possívies comorbidades, através dos indicadores epidemiológicos. Para tanto, realizamos uma abordagem retrospectiva dos números, destacando a prevalência da COVID-19, a partir dos casos confirmados no ano de 2020 até a data de 26 de janeiro de 2021. Trata-se de um estudo com metodologia transversal, de natureza qualitativa e quantitativa. Os documentos de patentes foram buscados nos Boletim Epidemiológico da Secretária de Saúde Pública (SESAP/RN), Laboratório Central (LACEN/RN), Kaggle - Coronavírus Brasil, Ministério da Saúde (MS) Departamento de Atenção Básica (DAB), Cadastro Nacional de Estabelecimentos de Saúde (CNES), Ambiente Virtual de Aprendizagem do SUS da Universidade Federal do Rio Grande do Norte (AVASUS/UFRN), Google COVID-19 Community Mobility Reports, Banco Interamericano de Desenvolvimento (BID) no Painel de Impacto do Coronavírus. No Brasil já são mais de 9.834.513 casos confirmados e quase 239.245 mil óbitos (dados coletados até de 15 de fevereiro de 2021) e no estado do Rio Grande do Norte ­ RN são 147.631 casos novos confirmados e 3.381 óbitos (dados de 15 de fevereiro de 2021). O cenário atual requer ações preventivas de autocuidado e resguardo coletivo, para que dessa forma, haja redução dos riscos do vírus infectar pessoas dos grupos mais vulneráveis, mas para isso é preciso haver envolvimento da população em massa.

The aim of this study was to investigate the experience of the COVID-19 pandemic in the city of Natal, RN, considering the age group of patients affected by the disease and their possible comorbidities, through epidemiological indicators. Therefore, we took a retrospective approach of the numbers, highlighting the prevalence of COVID-19, from the confirmed cases in the year 2020 until the date of January 26, 2021. This is a study with a transversal methodology, of a qualitative and quantitative nature. Patient documents were sought in the Epidemiological Bulletin of the Public Health Secretariat (SESAP/RN), Central Laboratory (LACEN/RN), Kaggle - Coronavirus Brazil, Ministry of Health (MH) Department of Primary Care (DPC), National Registry of Health Facilities (NRHF), SUS Virtual Learning Environment at the Federal University of Rio Grande do Norte (AVASUS/UFRN), Google COVID-19 Community Mobility Reports, Inter-American Development Bank (IDB) in the Coronavirus Impact Panel. In Brazil there are already more than 9,834,513 confirmed cases and almost 239,245 thousand deaths (data collected until February 15, 2021) and in the state of Rio Grande do Norte (RN) there are 147,631 confirmed new cases and 3,381 deaths (data from February 15, 2021). The current scenario requires preventive actions of self-care and collective protection, so that, in this way, there is a reduction in the risks of the virus infecting people from the most vulnerable groups, but this requires the involvement of the mass population.

Impact of the Coronavirus Infection in Pregnancy: A Preliminary Study of 141 Patients.

BACKGROUND: The novel coronavirus disease (COVID-19) is the most challenging health crisis that we are facing today. Against the backdrop of this pandemic, it becomes imperative to study the effects of this infection on pregnancy and its outcome. Hence, the present study was undertaken to evaluate the effects of COVID-19 infection on the maternal morbidity and mortality, the course of labour as well as the neonatal outcome. MATERIALS AND METHODS: A total of 977 pregnant women were included in the study, from 1st April to 15th May 2020 at a tertiary care hospital. There were 141 women who tested COVID positive and remaining 836 patients were included in the COVID negative group. Findings were compared in both the groups. RESULTS: The incidence of COVID positive pregnant women was found to be 14.43%. More patients delivered by LSCS in the COVID positive and the COVID negative group (50%) as compared to COVID negative group (47%), (p > 0.05). Low APGAR score (0-3) was observed in 2(1.52%) neonates of COVID positive mothers and in 15 (1.91%) neonates of COVID negative mothers. Overall most of the babies were healthy. Out of all babies tested, 3 were detected positive initially which were retested on day 5 and were found to be negative. CONCLUSION: There is no significant effect of COVID infection on maternal and foetal outcome in pregnancy and there is no evidence of vertical transmission of the COVID-19 infection but long-term follow-up of these babies is recommended.

Abstract Hoplias malabaricus (Characiformes, Erythrinidae), trahira, is a neotropical freshwater fish of economic and public health significance. A total of 45 specimens of H. malabaricus commercialized in the municipality of Magé, state of Rio de Janeiro, Brazil, were acquired between April 2016 and April 2018 to investigate the presence of nematode larvae. Twenty of the fish were found parasitized by 347 fourth-stage nematode larvae identified taxonomically as Eustrongylides sp. using morphological, morphometric and molecular data. The parasitic indices were: prevalence 44.44%, mean intensity 17.35, mean abundance 7.71, and range of infection 2-40. Infection sites were musculature, mesentery, abdominal cavity, and serosa of intestine, stomach and liver. This is the first report of Eustrongylides sp. larvae parasitizing H. malabaricus in the state of Rio de Janeiro.

Resumo Hoplias malabaricus (Characiformes, Erythrinidae), traíra, é um peixe neotropical de água doce que tem significante impacto na economia e saúde pública. De abril de 2016 a abril de 2018, foram adquiridos 45 espécimes de H. malabaricus comercializados no município de Magé, Estado do Rio de Janeiro, Brasil. Os peixes foram necropsiados e filetados para investigação da presença de larvas de nematoides. Vinte dos peixes coletados estavam parasitados por 347 larvas de nematoides, identificadas taxonomicamente como larvas de quarto estágio de Eustrongylides sp. usando-se dados morfológicos, morfométricos e moleculares, apresentando os seguintes valores: prevalência de 44,44%, intensidade média de 17,35, abundância média de 7,71, e amplitude de variação da infecção de 2-40. Os sítios de infecção foram musculatura, mesentério, cavidade abdominal e serosas do intestino, estômago e fígado.

Trypanorhynch cestodes parasitizing Mugil liza (Mugiliformes: Mugilidae) commercialized in the state of Rio de Janeiro, Brazil / Cestoides Trypanorhyncha parasitando Mugil liza (Mugiliformes: Mugilidae) comercializados no estado do Rio de Janeiro, Brasil

Abstract The aim of the present study was to identify, through morphological and morphometric analyses, the species of trypanorhynch cestodes found as plerocerci in the intestinal serosa of Mugil liza and to determine their parasitic indices. One hundred and fifty specimens of this mullet collected off the coast of the state of Rio de Janeiro were necropsied and the trypanorhynch cestodes found were fixed and preserved as whole mounts for morphological analysis. The plerocerci were identified as Callitetrarhynchus gracilis and Pterobothrium crassicole, both with a prevalence of 0.67%, an intensity of 1 and abundance of 0.0067, in single infections. This is the first record of a trypanorhynch cestode parasitizing M. liza in Brazil. Although the parasitic indexes were low, from a hygienic-sanitary perspective the plerocerci of these species are visible to the naked eye, and thus can disgust consumers and make marketing the fish unfeasible.

Resumo O presente estudo objetivou determinar taxonomicamente as espécies de plerocercos de cestoides Trypanorhyncha encontradas na serosa intestinal das tainhas Mugil liza, através do estudo morfológico e morfométrico e indicar seus índices parasitários. Foram coletados 150 espécimes desta espécie de tainha do litoral do estado do Rio de Janeiro. Após as necropsias, os cestoides Trypanorhyncha encontrados foram fixados e preservados em montagens permanentes para permitir a análise de suas estruturas morfológicas. Os plerocercos foram identificados como Callitetrarhynchus gracilis e Pterobothrium crassicole e ambas as espécies apresentaram prevalência de 0,67%, intensidade de 1 e abundância de 0,0067, em infecções únicas. Este é o primeiro registro de cestoides Trypanorhyncha parasitando M. liza no Brasil. Quanto ao aspecto higiênico-sanitário, vale ressaltar que, embora os índices parasitários registrados tenham sido baixos, os plerocercos dessas espécies estavam visíveis a olho nu, podendo causar repugnância ao consumidor e inviabilizar a comercialização do pescado.

Acanthocephalan parasites of the flounder species Paralichthys isosceles, Paralichthys patagonicus and Xystreurys rasile from Brazil / Acantocéfalos parasitos de espécies de linguados Paralichthys isosceles, Paralichthys patagonicus e Xystreurys rasile no Brasil

Abstract Flounders are commercially and economically important fish. A total of 120 specimens of flounders (60 Paralichthys isosceles, 30 Paralichthys patagonicus and 30 Xystreurys rasile) were collected off the coast of the state of Rio de Janeiro, Brazil. The fish were measured, necropsied and filleted, and then had their organs investigated for acanthocephalans. Taxonomic identification of the parasites was based on morphological, morphometric and genetic characters. Paralichthys isosceles and P. patagonicus were parasitized by juveniles of Serrasentis sagittifer, Bolbosoma turbinella, Corynosoma australe and C. cetaceum; Xystreurys rasile was parasitized by C. australe. Genetic characterization confirmed the identification of specimens of Bolbosoma turbinella and Corynosoma australe, as demonstrated by phylogenetic analyses using both ITS and cox1 molecular targets. Parasite indices of prevalence, intensity, mean intensity, abundance, mean abundance, and range of infection, as well as infection site, were evaluated for each parasite species. This is the first report of S. sagittifer parasitizing P. isosceles and P. patagonicus, and B. turbinella parasitizing P. patagonicus.

A caracterização genética confirmou a identificação dos espécimes de Bolbosoma turbinella e Corynosoma australe, como demonstrado por análises filogenéticas usando ambos marcadores moleculares ITS e cox1. Foram analisados os índices parasitários: prevalência, intensidade, intensidade média, abundância, abundância média, amplitude de variação da infecção e sítio de infecção de cada espécie de parasito. Este é o primeiro registro de S. sagittifer parasitando P. isosceles e P. patagonicus, e de B. turbinella parasitando P. patagonicus.

Acanthocephalan parasites of the flounder species Paralichthys isosceles, Paralichthys patagonicus and Xystreurys rasile from Brazil.

Flounders are commercially and economically important fish. A total of 120 specimens of flounders (60 Paralichthys isosceles, 30 Paralichthys patagonicus and 30 Xystreurys rasile) were collected off the coast of the state of Rio de Janeiro, Brazil. The fish were measured, necropsied and filleted, and then had their organs investigated for acanthocephalans. Taxonomic identification of the parasites was based on morphological, morphometric and genetic characters. Paralichthys isosceles and P. patagonicus were parasitized by juveniles of Serrasentis sagittifer, Bolbosoma turbinella, Corynosoma australe and C. cetaceum; Xystreurys rasile was parasitized by C. australe. Genetic characterization confirmed the identification of specimens of Bolbosoma turbinella and Corynosoma australe, as demonstrated by phylogenetic analyses using both ITS and cox1 molecular targets. Parasite indices of prevalence, intensity, mean intensity, abundance, mean abundance, and range of infection, as well as infection site, were evaluated for each parasite species. This is the first report of S. sagittifer parasitizing P. isosceles and P. patagonicus, and B. turbinella parasitizing P. patagonicus.

Cestoide trypanorhyncha Callitetrarhynchus gracilis (Rudolphi, 1819) Pintner, 1931 parasitando Balistes capriscus Gmelin, 1789 coletados no litoral do Estado do Rio de Janeiro, Brasil / Trypanorhyncha cestode Callitetrarhynchus gracilis (Rudolphi, 1819) Pintner, 1931 parasitizing Balistes capriscus Gmelin, 1789 collected off the coast of the State of Rio de Janeiro, Brazil

O controle de parasitos faz parte das inspeções oficiais de pescado, pois o consumo de espécimes parasitados pode oferecer risco à saúde humana. A presença de cestoides Trypanorhyncha causa aspecto repugnante que pode condenar o pescado como impróprio para consumo. Além disso, tem sido relacionados com potencial alergênico em modelo murino. Entre março e novembro de 2017 foram adquiridos 42 espécimes de Balistes capriscus Gmelin, 1789, peixe-porco, nos mercados do município de Niterói, Rio de Janeiro. Dos 42 peixes analisados, 4 estavam parasitados por plerocercos de Callitetrarhynchus gracilis (Rudolphi, 1819) Pintner, 1931 com prevalência de 10,5%, intensidade média de infecção de 1 parasito e a abundância média de 0,09. A presença desse cestoide ressalta sua importância higiênico-sanitária em B. capriscus.

Pterobothrium sp. parasitando linguado, Xystreurys rasile (Jordan, 1891), coletados no litoral do Estado do Rio de Janeiro, Brasil e sua importância na inspeção do pescado / Pterobothrium sp. parasitizing flounders, Xystreurys rasile (Jordan, 1891), collected off the coast the State of Rio de Janeiro, Brazil and its fishing inspection importance

Alguns parasitos, podem conferir aspecto repugnante ao pescado, sendo condenados pelo Serviço de Inspeção, quando na indústria de beneficiamento. Entre novembro de 2010 e maio de 2018 foram adquiridos 36 espécimes de Xystreurys rasile em mercados de pescados no município do Rio de Janeiro, Brasil. Os peixes foram identificados, medidos, pesados e necropsiados. Os cestoides foram processados segundo as técnicas usuais em helmintologia. Cinco linguados estavam parasitados por 29 cestoides do gênero Pterobothrium, os índices parasitários foram: prevalência (14%), intensidade média (5,8), abundância média (0,8) e amplitude de infecção (2-12) e os sítios de infecção foram estômago, intestino, rim, fígado, serosas do estômago, baço e fígado e cavidade abdominal. Este é o primeiro registro de Pterobothrium sp. parasitando X. rasile.
