Gastrointestinal parasites in captive wild birds in Mineiros, Goiás, Brazil.

Studying parasites in captive wild birds is vital for their health, well-being, biodiversity preservation, species conservation, and safeguarding of both individual birds and ecosystems. It holds significance for public health by identifying potential zoonotic risks. We aimed to describe the occurrence of gastrointestinal parasites in captive wild birds from a Conservation Institute in Brazilian Cerrado biome. Fresh fecal samples were collected from 17 captive wild birds (Anodorhynchus hyacinthinus, Ara ararauna, Ara chloropterus, Ara macao, Megascops choliba, Pteroglossus castanotis, Ramphastos dicolorus, Ramphastos tucanus and Strix huhula) at a Conservation Institution in Mineiros, state of Goiás. The samples were processed for Willis' simple flotation and Hoffman's spontaneous sedimentation examinations to identify parasitic forms of gastrointestinal endoparasites. Macaw aviary birds (Ar. ararauna, Ar. chloropterus and Ar. macao) showed higher positivity, with all six fecal samples positive for helminths or protozoa. In contrast, captive toucans showed only two positive results (P. castanotis and R. dicolorus). An. hyacinthinus showed Ascarididae, Capillarinae and Trematoda eggs; whereas S. huhula had Ascarididae eggs. Regular parasitological examinations are essential for the timely detection and treatment of gastrointestinal infections in captive birds, thereby enhancing overall bird management.

Androgen-deprivation therapy and cognitive decline in the NEON-PC prospective study during the COVID-19 pandemic.

BACKGROUND: Androgen-deprivation therapy (ADT) has been associated with cognitive decline, but results are conflicting. This study describes changes in cognitive performance in patients with prostate cancer, according to ADT, during the first year after prostate cancer diagnosis. PATIENTS AND METHODS: Patients with prostate cancer treated at the Portuguese Institute of Oncology of Porto (n = 366) were evaluated with the Montreal Cognitive Assessment (MoCA), before treatment and after 1 year. All baseline evaluations were performed before the coronavirus disease 2019 (COVID-19) pandemic and 69.7% of the 1-year assessments were completed after the first lockdown. Cognitive decline was defined as the decrease in MoCA from baseline to the 1-year evaluation below 1.5 standard deviations of the distribution of changes in the whole cohort. Participants scoring below age- and education-specific normative reference values in the MoCA were considered to have cognitive impairment. Age- and education-adjusted odds ratios (aORs) were computed for the association between ADT and cognitive outcomes. RESULTS: Mean MoCA scores increased from baseline to the 1-year evaluation (22.3 versus 22.8, P < 0.001). Cognitive decline was more frequent in the ADT group, and even more after the onset of the COVID-19 pandemic (aOR 6.81 versus 1.93, P for interaction = 0.233). The 1-year cumulative incidence of cognitive impairment was 6.9% (9.1% before and 3.7% after the pandemic onset), which was higher among patients receiving ADT, but only after the pandemic (aOR 5.53 versus 0.49, P for interaction = 0.044). CONCLUSIONS: ADT was associated with worse cognitive performance of patients with prostate cancer, mostly among those evaluated after the first COVID-19 lockdown.

Gastrointestinal parasites in captive and free-living wild birds in Goiania Zoo / Parasitas gastrointestinais em aves silvestres em cativeiro e de vida livre no Zoológico de Goiânia

Helminths are endoparasites that infect a variety of bird species. Endoparasite infections can cause severe diseases, including kill captive avian hosts and represents a problem to maintenance and conservation. The eggs and larval forms of these parasites are usually eliminated in the host feces. The main interest of this study is to report the occurrence of eggs and oocysts in feces from captive wild birds in Goiânia Zoo and free-living birds in its surroundings. The fecal samples were subjected to parasitological examination to identify the presence of helminths and to classify their eggs based on morphological characteristics. Eggs of nematode parasites (Positive/N) were identified as Ascaridia spp. in Brotogeris chiriri (2/2), Dromaius novaehollandiae (1/1) and Rhea americana (2/2); Ascarididae in Pavo cristatus nigripensis (1/1); Capillaria spp. in Ara chloropterus (1/1) and Penelope jacucaca (1/1); Capillaria plagiaticia in Anodorhynchus hyacinthinus (1/2) and Ara spp. (2/2); Capillaria venusta in Rhamphastus tucanus (1/2); and unidentified nematode eggs from Amazona amazonica (2/2). Eimeria spp. oocyst was founded in feces from A. hyacinthinus (1/2). Considering free-living birds, Diphyllobothrium spp. eggs were founded in Ardea alba (2/2) and Nycticorax nycticorax (2/3). Co-infection of Eustrongylides spp. was founded in A. alba (1/2). This is the first occurrence of: Ascaridia spp. parasitizing B. chiriri; and C. venusta parasitizing R. tucanus. In conclusion, the helminth eggs found in the abovementioned host bird species are consistent with those reported in the literature, and treatment and control protocols were based on their identification.

First record of Trichodina heterodentata (Ciliophora: Trichodinidae) in banded knifefish Gymnotus carapo (Gymnotidae) cultured in Brazil / Primeiro registro de Trichodina heterodentata (Ciliophora: Trichodinidae) em tuvira Gymnotus carapo (Gymnotidae), cultivado no Brasil

The aim of this study was to report the first record of Trichodina heterodentata in banded knifefish Gymnotus carapo. Banded knifefish cultivated in the municipality of Jataí, state of Goiás, in the central western region of Brazil, experienced fish mortality rates of 3-4% per tank. Macroscopic analysis found that fish had lesions on their skin and gills. Smears of the integument and gills were confectioned and air-dried at room temperature and impregnated with silver nitrate to identify the Trichodinidae species causing the lesions. The trichodinid were identified as T. heterodentata, and their characteristics were compared to those from T. heterodentata recorded from other species of host fish. It was observed that the presence of T. heterodentata was associated with inadequate fish management, low water quality, high rates of stocking density, and inadequate nutritional management.

Phoretic mites (Rhinoseius spp. ) in Apodiformes from Cerrado and Pantanal Biomes in midwestern Brazil / Ácaros Foréticos (Rhinoseius spp. ) em Apodiformes dos Biomas Cerrado e Pantanal no Centro-Oeste do Brasil

Abstract Nasal mites are commonly found in hummingbirds (Apodiformes). In most cases, endoparasitic mites were reported to parasitize the respiratory system, particularly the anterior nasal chambers, larynx, trachea, lungs, and the air and conjunctival sacs. However, some mites are only carried by hummingbirds, because flowers serving as a nutrient source for these small mites, such as for Apodiformes, a tropical nectar-feeding in their natural habitat. From August 2012 to May 2014, humminbirds were captured using mist nets, and examined for the presence of nasal mites (identified according to specific keys) in the Pantanal, and Cerrado biomes, from the Mato Grosso state, midwestern Brazil. Overall, 76 Apodiform specimens, from the Trochilidae family were captured, and 20 female nasal mites, identified as being from the Rhinoseius genus, were collected from eight hosts (10.5%), of the following species: Amazilia fimbriata, Amazilia versicolor, Eupetonema macroura, and Thalurania furcata. The Rhinoseius spp. has been reported on, in many ecosystems in the Americas, including Brazil, however, this is the first report on Apodiformes from the Pantanal biome. Phoretic mites are not responsible for direct damage to the population of Apodiformes, as they are not pathogenic. However, they compete for food with hummingbirds and decrease the quantity of food available in the environment. They also affect the reproductive dynamics of plants, feed on pollen, and interfere with the intricacies of the biodiversity where they live.

Resumo Os ácaros nasais são comumente encontrados em beija-flores (Apodiformes). Na maioria dos casos, os ácaros foram relatados como endoparasitas, parasitando o sistema respiratório, particularmente as câmaras nasais anteriores, a laringe, a traqueia, os pulmões e os sacos aéreos e conjuntivais. No entanto, alguns ácaros são transportados apenas por beija-flores, pois flores servem como fonte de nutrientes para esses pequenos ácaros, assim como para Apodiformes tropicais alimentados de néctar em seu habitat natural. De agosto de 2012 a maio de 2014, beija-flores foram capturadas com redes de neblina e examinadas quanto à presença de ácaros nasais (identificados de acordo com chaves específicas) nos biomas Pantanal e Cerrado, no estado do Mato Grosso, Centro-Oeste do Brasil. No total, 76 exemplares Apodiformes da família Trochilidae foram capturados e 20 fêmeas de ácaros nasais, identificados como pertencentes ao gênero Rhinoseius, foram coletados de oito hospedeiros (10,5%), das seguintes espécies: Amazilia fimbriata, Amazilia versicolor, Eupetonema macroura e Thalurania furcata. Rhinoseius spp. foi relatado em muitos ecossistemas nas Américas, incluindo o Brasil, no entanto, este é o primeiro relato em Apodiformes do bioma Pantanal. Os ácaros foréticos não são responsáveis ​​por danos diretos à população de Apodiformes, pois não são patogênicos. No entanto, eles competem por comida com beija-flores e diminuem a quantidade de comida disponível no ambiente. Eles também afetam a dinâmica reprodutiva das plantas, se alimentam de pólen e interferem nas interações da biodiversidade em que vivem.

Which One Is the Best for Living Donation: A Multiple-Artery Left Kidney Nephrectomy or a Right Kidney Nephrectomy?

INTRODUCTION: The current approach in living-donor kidney transplant is to preserve the best kidney for the donor and harvest the contralateral one. Due to a shorter renal vein and a greater incidence of venous thrombosis, left kidneys are more frequently elected. Notwithstanding, arterial anatomy may be complex and thus render the transplantation procedure more difficult and prone to complications. OBJECTIVES: To analyze the outcomes after multiple-artery left kidney nephrectomy (MALKN) and right kidney nephrectomy (RKN). RESULTS: Seventy-three cases were performed from 1999 to 2017 in our institution: 34 MALKN and 39 RKN. The mean operative time was significantly longer in MALKN. Warm ischemia time, donor and receptor hospital stay, and postoperative complications did not differ between groups. There was a positive correlation between renal arteries' ostia distance in MALKN and the duration of warm ischemia period. There was no significant difference in the incidence of acute tubular necrosis, first-year variations in serum creatinine, and glomerular filtration rate between groups. Long-term graft survival did not significantly differ between groups. Three cases of vein thrombosis after RKN were reported with graft loss. CONCLUSION: The safety and efficacy of MALKN does not differ from RKN, although there appears to be a higher incidence of vein thrombosis after right kidney transplantation. Despite being technically more demanding, particularly in cases with distant artery ostia, MALKN could be a better option than RKN for living donation, expanding the available donor pool, although more studies are needed to affirm this conclusion.

Multi-hospital point prevalence study of healthcare-associated infections in 28 adult intensive care units in Brazil.

BACKGROUND: Healthcare-associated infection (HAI) represents a major problem for patient safety worldwide. AIM: To provide an up-to-date picture of the extent, aetiology, risk factors and patterns of infections in intensive care units (ICUs) in 28 Brazilian hospitals of different sizes. METHODS: A one-day point prevalence survey in 2016 enrolled the ICUs of hospitals from the 12 meso-regions in Minas Gerais state, south-east Brazil. Hospitals were classified as university or non-university hospitals. All patients with >48 h of admission to the study ICUs at the time of the survey were included. FINDINGS: In total, 303 patients were studied; of these, 155 (51.2%) were infected and 123 (79.4%) had at least one ICU-acquired infection. The most common ICU-acquired infections were pneumonia (53.0%) and bloodstream infection (27.6%). One hundred and nineteen bacterial isolates were cultured; the most common were Acinetobacter baumannii (27.1%), Pseudomonas aeruginosa (27.1%) and Staphylococcus aureus (39.0%). According to type of infection, the most common pathogens were P. aeruginosa (30.4%) in pneumonia, coagulase-negative staphylococci (23.4%) and Enterobacteriaceae (23.4%) in bloodstream infections, and Enterobacteriaceae (47.6%) in urinary tract infections. CONCLUSION: This study found that the overall prevalence of ICU-acquired infections in surveyed Brazilian hospitals was higher than that reported in most European countries and the USA. A greater proportion of infections were caused by non-fermenting Gram-negative bacteria. These observations, along with a high rate of antimicrobial use, illustrate the urgent need for HAIs to be a priority in the public health agenda of Brazil.

Overall, 76 Apodiform specimens, from the Trochilidae family were captured, and 20 female nasal mites, identified as being from the Rhinoseius genus, were collected from eight hosts (10.5%), of the following species: Amazilia fimbriata, Amazilia versicolor, Eupetonema macroura, and Thalurania furcata. The Rhinoseius spp. has been reported on, in many ecosystems in the Americas, including Brazil, however, this is the first report on Apodiformes from the Pantanal biome. Phoretic mites are not responsible for direct damage to the population of Apodiformes, as they are not pathogenic. However, they compete for food with hummingbirds and decrease the quantity of food available in the environment. They also affect the reproductive dynamics of plants, feed on pollen, and interfere with the intricacies of the biodiversity where they live.

Resumo Os ácaros nasais são comumente encontrados em beija-flores (Apodiformes). Na maioria dos casos, os ácaros foram relatados como endoparasitas, parasitando o sistema respiratório, particularmente as câmaras nasais anteriores, a laringe, a traqueia, os pulmões e os sacos aéreos e conjuntivais. No entanto, alguns ácaros são transportados apenas por beija-flores, pois flores servem como fonte de nutrientes para esses pequenos ácaros, assim como para Apodiformes tropicais alimentados de néctar em seu habitat natural. De agosto de 2012 a maio de 2014, beija-flores foram capturadas com redes de neblina e examinadas quanto à presença de ácaros nasais (identificados de acordo com chaves específicas) nos biomas Pantanal e Cerrado, no estado do Mato Grosso, Centro-Oeste do Brasil. No total, 76 exemplares Apodiformes da família Trochilidae foram capturados e 20 fêmeas de ácaros nasais, identificados como pertencentes ao gênero Rhinoseius, foram coletados de oito hospedeiros (10,5%), das seguintes espécies: Amazilia fimbriata, Amazilia versicolor, Eupetonema macroura e Thalurania furcata. Rhinoseius spp. foi relatado em muitos ecossistemas nas Américas, incluindo o Brasil, no entanto, este é o primeiro relato em Apodiformes do bioma Pantanal. Os ácaros foréticos não são responsáveis por danos diretos à população de Apodiformes, pois não são patogênicos. No entanto, eles competem por comida com beija-flores e diminuem a quantidade de comida disponível no ambiente. Eles também afetam a dinâmica reprodutiva das plantas, se alimentam de pólen e interferem nas interações da biodiversidade em que vivem.

From Open to Laparoscopic Living-donor Nephrectomy: Changing the Paradigm in a High-volume Transplant Center.

In 1995, Ratner et al reported the first laparoscopic living-donor nephrectomy, and since then this approach is gradually replacing traditional open surgery. The learning curve of the procedure is still unclear and lessons taken from initial experience series are of utmost importance. We retrospectively analyzed our initial 50 living-donor laparoscopic nephrectomies, of which 90% were performed on the left side. Renal vascular variation occurred in 28% of donors. The median age and body mass index of the donors were 50 years (IQR 39-55) and 24.65 kg/m(2) (IQR 22.5-27.3), respectively. The median operative time and warm ischemia time were 160 minutes (IQR 141-178) and 240 seconds (IQR 210-280), respectively. Estimated blood loss was 60 mL (IQR 60-127.5). The serum creatinine of the receptors was 97.6 µmol/L (IQR 87.5-139.6) 1 month after transplant. Overall, there were 5 complications, including 2 (4%) open conversions, 1 (2%) incisional hernia, 1 (2%) graft loss, and 1 (2%) reintervention. The body mass index and the multiple arteries did not influence the operative time and warm ischemia time or the recipient's serum creatinine level. Along the series, there was a significant reduction in the operative time (Spearman ρ = -5.2; P < .001), but no significant differences were found for warm ischemia time, blood loss, or serum creatinine of the recipients (P > .05). Laparoscopic donor nephrectomy is a safe procedure in centers experienced in laparoscopic surgery; however, the learning curve plateau was not reached after the initial 50 cases.

Detecção de Theileria equi e Babesia caballi e anticorpos anti-Ehrlichia spp. em equídeos do Pantanal Mato-Grossense, Brasil / Detection of Theileria equi, Babesia caballi and anti-Ehrlichia spp antibodies in equides from the Pantanal of Mato Grosso State

O presente estudo avaliou equídeos de 19 fazendas da região do Pantanal Mato-Grossense, sendo 121 equídeos testados pela reação em cadeia pela polimerase (PCR), para detectar fragmentos dos genes dos seguintes gêneros: Babesia, Theileria, Anaplasma, Ehrlichia, e Neorickettsia, e pela reação de imunofluorescência indireta (RIFI), para detectar anticorpos anti-Ehrlichia spp. Das amostras testadas na PCR, 17 (14,0%) animais de nove (47,3%) fazendas foram positivos. Das amostras positivas, 16 foram 100% idênticas a sequencias de Theileria equi e uma foi 99% similar à sequência de Babesia caballi, todas disponíveis no GenBank. Pela RIFI, 48 (39,6%) equídeos foram soropositivos para antígenos de E. canis, sendo 40 (83,3%) amostras com títulos de 40 e oito (16,6%) com títulos de 320. Todas as fazendas avaliadas (100%) apresentaram equídeos soropositivos. Os resultados do presente estudo demonstram que T. equi e B. caballi infectam equinos na região, e a presença de anticorpos anti-Ehrlichia spp. indica a circulação de espécies antigenicamente relacionadas aos gêneros Ehrlichia e Anaplasma, apesar de a negatividade nos exames de PCR indicar provável processo crônico desses agentes.

The present study evaluated 121 equids from 19 ranches in the Pantanal region of Mato Grosso State through Polimerase Chain Raction (PCR) to detect Babesia, Theileria, Anaplasma, Ehrlichia and Neorickettsia partial genes and the Imunofluorescent Antibody Test (IFAT) to evaluate anti-Ehrlichia spp. antibodies. From the total tested in PCR, 17 (14.0%) equids from 9 (47.3%) farms were positive, and 16 yielded amplicons 100% identical to Theileria equi and one presented 99% similarity to Babesia caballi available on GenBank. Forty eight (39.6%) equids were positive by IFAT and 40 showed titers of 40 (83.3%) and 8 showed titers of 320 (16.6%). All ranches (100%) presented seropositive equids. Our results showed that T. equi and B. caballi are infecting equids in the region and the presence of anti-Ehrlichia antibodies suggests that species closely related to the genera Ehrlichia and Anaplasma are circulating among the equid local population. Moreover, the negative results in PCR is possibly related to the chronic infection phase.

Living versus cadaveric-donor renal transplant recipients: a comparison on sexual function.

Erectile dysfunction is experienced by 50% of men with end-stage renal disease (ESRD) and uremia. The origin of this dysfunction is multifactorial. The aim of this study was to compare living donor versus cadaveric donor transplant recipients regarding male sexual function. Seventy-seven sexually active male kidney transplant recipients (44 from living donors; 33 from cadaveric donors) were randomly selected from our single-center prospective database of 2016 renal transplants. Epidemiological and clinical data were collected between June 2010 and June 2011. Male sexual function was evaluated with the International Index of Erectile Function questionnaire (IIEF-15). We assessed the prevalence of male sexual dysfunction according to established cutoff points for each of the IIEF-15 domains. Mann-Whitney and Pearson's chi- square statistical tests were used to compare continuous and categorical variables, respectively. The median age at the time of completion of the questionnaires was 43 and 51 years (P = .003) with median times from transplantation was of 36 and 42 months for living donor and cadaveric donor recipients, respectively (P = .31). Median durations of ESRD before surgery were 17.5 and 57 months for living donor and cadaveric donor recipients, respectively (P < .001). Living donor and cadaveric donor recipients had median creatinine clearance values of 55 and 57 mL/min, respectively (P = .44). Median time after renal transplantation for first sexual intercourse was 1 and 2 months for living donor and cadaveric donor recipients, respectively (P = .35). Median body mass indices for living donor and cadaveric donor recipients were 24.8 and 24, respectively (P = .31). Regarding sexual function domains, there were significant differences only for intercourse satisfaction. In our cohort, living donor recipients tended to be younger, have shorter time of ESRD, and less incidence of hypertension or diabetes mellitus but with greater tobacco use. In conclusion, living donor transplantation exerted a favorable impact on sexual function.

Bacterial colonization of pressure ulcers: assessment of risk for bloodstream infection and impact on patient outcomes.

BACKGROUND: Pressure ulcers (PUs) represent a major problem for hospitalized patients, health professionals and society. AIM: To evaluate the impact of in-hospital PUs as a reservoir of multidrug-resistant organisms (MDROs), risk factor for bacteraemia and predictor of poor prognosis. METHODS: A prospective cohort study of patients with stage II or greater PUs hospitalized in a tertiary acute care university teaching hospital for more than 48 h was performed to evaluate colonization/infection by potential and/or multi-resistant hospital pathogens from April to December 2005 and from August 2009 to April 2010. FINDINGS: A total of 145 patients with stage II or greater PUs were included. Of these, 76.5% (111/145) had PUs colonized and/or infected with either S. aureus (20.7%), Gram-negative bacilli (32.5%), or both (46.8%) and most were MDROs (64.8%). Bacteraemia was detected in 50.5% (56/111) of the patients. The ulcers were considered to be the probable source of bacteraemia in 53.6% (30/56) of the episodes. Prior administration of antibiotics (P = 0.04) and infected wound (P < 0.001) were the variables independently associated with bloodstream infection as well as associated with a higher 30-day mortality rate; risk factors for the latter included hospitalization in ICU (P = 0.03) and mechanical ventilation use (P = 0.05). CONCLUSIONS: Our results suggest that besides being a major reservoir of MDROs, patients with PUs constitute a high-risk population for bacteraemia with a poor outcome. Broad-spectrum antibiotics and infected wound were independent factors predisposing patients to both bacteraemia and death.

Analysis of SNAP25 mRNA expression and promoter DNA methylation in brain areas of Alzheimer's Disease patients.

Alzheimer's Disease (AD) is the most common cause of dementia in elderly people. The presynaptic terminal is an important site of pathological changes in AD, leading to synaptic loss in specific brain regions, such as in the cortex and hippocampus. In this study, we investigated synaptosomal-associated protein, 25-kDa (SNAP25) mRNA levels and promoter DNA methylation in post mortem brain tissues (entorhinal and auditory cortices and hippocampus) from healthy elderly and AD subjects as well as in peripheral blood leukocytes of young, healthy elderly and AD patients. mRNA quantification was performed by quantitative Reverse Transcription Polymerase Chain Reaction (qRT-PCR) using the ΔΔC(T) method and promoter DNA methylation was quantified by mass spectrometry using the Sequenom EpiTYPER platform. We observed a significant decrease in SNAP25 expression in AD across all the three brain regions in relation to the healthy elderly subjects, suggesting impairment in synaptic function. The changes in the auditory cortex reflected those observed in the hippocampus and entorhinal cortex, the primary areas affected in AD. However, no AD-associated differences in SNAP25 promoter DNA methylation were observed suggesting that other mechanisms may be involved in mediating the observed gene expression changes.
