Knowledge of blood parasites in Brazilian chelonians is limited, since they have been recorded in only six species. Mesoclemmys vanderhaegei (Bour) is a freshwater turtle with a wide geographic distribution in Brazil, but there is little information about its natural history. This paper reports on a study of the prevalence and infection intensity of a haemogregarine in two subpopulations of M. vanderhaegei. The study was conducted in two areas of Cerrado in the Upper Paraguay River basin in the state of Mato Grosso, Brazil, between November 2010 and August 2013. Ninety-five (53%) of the 179 turtles captured were positive for haemogregarine parasites. The parasitic forms observed were two morphotypes of intraerythrocytic gametocytes. The prevalence differed between size classes, increasing significantly according to the animals' body size. There was no significant difference between prevalence and sex, or between sampling periods. The mean parasite intensity was 9 parasites/2,000 erythrocytes (0.45%) and the parasite population presented an aggregated distribution, with an aggregation index of 19 and discrepancy of 0.772. This is the first record of a hemoparasite in the freshwater turtle M. vanderhaegei., Vinícius C. Goes, Elizângela S. Brito, Rafael M. Valadão, Camila O. Gutierrez, Amanda M. Picelli, Lúcio A.

Thirty-two specimens of the Nile crocodile, Crocodylus niloticus Laurenti (Reptilia: Crocodylidae), from the Kruger National Park, South Africa, and its vicinity were examined for pentastomid parasites during 1995 to 1999 and 2010 to 2011. Pentastomid parasites occurred throughout the year and were widespread in the study area with an overall prevalence of 97% and an overall mean abundance of 23.4 (0-81). Pentastome assemblages comprised six species in three sebekid genera: Alofia nilotici Riley et Huchzermeyer, 1995, A. simpsoni Riley, 1994, Leiperia cincinnalis Sambon, 1922, Sebekia cesarisi Giglioli in Sambon, 1922, S. minor (Wedl, 1861) and S. okavangoensis Riley et Huchzermeyer, 1995. The possible influence of host age, gender and geographic location (river system) on pentastome prevalence, abundance and species richness was investigated. Generally, neither host age, gender nor locality did affect infracommunities, likely because all hosts examined were adult or subadult and displayed comparable foraging behaviour, resulting in similar exposure pathways to fish intermediate hosts. Additionally, the longevity of pentastomids would contribute to accumulative infections as hosts mature. Structuring of pentastome assemblages was observed in as far as S. minor was the dominant species based on overall prevalence and abundance, followed by the equally common species S. cesarisi and L. cincinnalis. With an overall prevalence ranging from 34% to 41% and relatively low abundances, A. nilotici, A. simpsoni and S. okavangoensis form the rarer component of pentastome communities., Kerstin Junker, Frikkie Calitz, Danny Govender, Boris R.

The care of patients with severe mental illness (SMI) is often narrowed down to the treatment of biological symptoms of the disease, whilst other psychosocial factors supporting mental health are often neglected. One of these factors influencing disease progression, compliance, self-concept, and motivation for treatment is parenthood. The first step to turning attention to this issue is to be aware of the prevalence of children living with a parent with SMI and the prevalence of parenting among SMI patients. This review aims to assess the current state of knowledge regarding methodological approaches, the prevalence rates of parenthood, the number of children living with a parent with SMI, and the sociodemographic characteristics of these families. A total of 1,156 records were retrieved from EBSCO Discovery in December 2021, and fifteen published studies addressed the review questions. The studies took various approaches to measure prevalence - an epidemiological approach, a census approach, a design in which data from national registries were analysed, or cross-sectional studies in a clinical population. Nine studies investigated the prevalence of parenthood among patients with SMI, and six studies quantified the number of children living with a parent with mental illness. 1/3 of mental health service clients were parents, and 1 to 2 children out of 10 have a parent with mental illness.Parents with SMI face lower education, lower employment, lower income, higher rates of comorbid substance abuse, and higher rates of single parenthood. The aim of the review is not to give a definitive answer to the question of prevalence as much as to point out that there is not a marginal number of children living with a parent with a psychiatric disorder. and Péče o pacienty se závažným duševním onemocněním (SMI) se často zužuje na léčbu biologických příznaků nemoci, zatímco ostatní psychosociální faktory podporující duševní zdraví jsou často opomíjeny. Jedním z těchto faktorů ovlivňujících průběh léčby, komplianci, sebepojetí pacienta a motivaci k léčbě, je rodičovství. Prvním krokem k obrácení pozornosti k této problematice je uvědomění si míry prevalence dětí žijících s rodičem se SMI a míry prevalence rodičovství mezi pacienty se SMI. Cílem tohoto přehledu je zhodnotit metodologické přístupy využívané k měření prevalence, míru prevalence rodičovství, počet dětí žijících s rodičem se SMI a sociodemografické charakteristiky těchto rodin. V databázi EBSCO Discovery bylo v prosinci 2021 vyhledáno celkem 1 156 záznamů, výběrová kritéria splnilo patnáct publikovaných studií, které byly zařazeny do přehledu. Studie využívaly různé přístupy k měření prevalence - epidemiologický přístup, přístup založený na cenzu, design, v němž byla analyzována data z národních registrů, nebo průřezové studie v klinické populaci. Devět studií zkoumalo prevalenci rodičovství u pacientů s duševním onemocněním a šest studií kvantifikovalo počet dětí žijících s rodičem s duševním onemocněním. Rodiče tvořili 1/3 klientů psychiatrických zařízení a 1 až 2 děti z 10 mají rodiče s duševním onemocněním. Rodiče se SMI se potýkají s nižším vzděláním, nižší zaměstnaností, nižšími příjmy, vyšší mírou komorbidního užívání návykových látek a vyšší mírou samoživitelství. Cílem přehledu není dát definitivní odpověď na otázku prevalence, ale spíše poukázat na to, že dětí žijících s rodičem s psychiatrickou poruchou není zanedbatelné množství.
