Could nanotechnology improve exercise performance? Evidence from animal studies

Abstract This review provides the current state of knowledge regarding the use of nutritional nanocompounds on exercise performance. The reviewed studies used the following nanocompounds: resveratrol-loaded lipid nanoparticles, folic acid into layered hydroxide nanoparticle, redox-active nanoparticles with nitroxide radicals, and iron into liposomes. Most of these nutritional nanocompounds seem to improve performance in endurance exercise compared to the active compound in the non-nanoencapsulated form and/or placebo. Nutritional nanocompounds also induced the following physiological and metabolic alterations: 1) improved antioxidant activity and reduced oxidative stress; 2) reduction in inflammation status; 3) maintenance of muscle integrity; 4) improvement in mitochondrial function and quality; 5) enhanced glucose levels during exercise; 6) higher muscle and hepatic glycogen levels; and 7) increased serum and liver iron content. However, all the reviewed studies were conducted in animals (mice and rats). In conclusion, nutritional nanocompounds are a promising approach to improving exercise performance. As the studies using nutritional nanocompounds were all conducted in animals, further studies in humans are necessary to better understand the application of nutritional nanocompounds in sport and exercise science.

Effect of Speaking Valves on Tracheostomy Decannulation

Abstract Introduction Despite several pediatric tracheostomy decannulation protocols there remains tremendous variability in practice. The effect of tracheostomy capping on decannulation has been studied but the role of speaking valves (SVs) is unknown. Objective Given the positive benefits SVs have on rehabilitation, we hypothesized that SVs would decrease time to tracheostomy decannulation. The purpose of the present study was to evaluate this in a subset of patients with chronic lung disease of prematurity (CLD). Methods A retrospective chart review was performed at a tertiary care children's hospital. A total of 105 patients with tracheostomies and CLD were identified. Data collected included demographics, gestational age, congenital cardiac disease, airway surgeries, granulation tissue excisions, SV and capping trials, tracheitis episodes, and clinic visits. Statistics were performed with logistic and linear regression. Results A total of 75 patients were included. The mean gestational age was 27 weeks (standard deviation [SD] =3.6) and the average birthweight was 1.1 kg (SD = 0.6). The average age at tracheostomy was 122 days (SD = 63). A total of 70.7% of the patients underwent decannulation and the mean time to decannulation (TTD) was 37 months (SD = 19). A total of 77.3% of the patients had SVs. Those with an SV had a longer TTD compared to those without (52 versus 35 months; p = 0.008). Decannulation was increased by 2 months for every increase in the number of hospital presentations for tracheitis (p =0.011). Conclusion The present study is the first, to our knowledge, to assess the effect of SVs on tracheostomy decannulation in patients with CLD showing a longer TTD when SVs are used.

Challenges of managing HIV cytomegalovirus co-infection in the presence of pancytopenia

A 60-year-old male patient who presented with generalized weakness and low-grade fever was diagnosed to be human immunodeficiency virus (HIV) positive with a CD4 count of 17. Routine laboratory investigations revealed pancytopenia. Serum cytomegalovirus (CMV) DNA polymerase chain reaction (PCR) was positive and fundoscopy showed CMV retinitis in the right eye. The patient was started on tablet valganciclovir. After 2 weeks, the patient was brought back in an altered sensorium. He was found to have hyponatremia which was corrected. He was started on antiretroviral therapy and tablet valganciclovir was continued. The patient came back again after one and a half months with a urinary tract infection and fissure-in-ano. He was found to have severe neutropenia. Valganciclovir was stopped. He was started on injection granulocyte colony-stimulating factor. The patient clinically improved and his hematological parameters became normal. Patients having HIV and CMV co-infection with pre-existing pancytopenia have to be closely monitored as the medicines used for treatment can exacerbate the existing conditions.

Evaluation of the Biochemical, Physicochemical and Microbiological Quality of Soft Drinks Sold in Some Elementary School of Williamsville (Abidjan, Côte d’Ivoire)

The sale of soft drinks in and around primary schools is recurrent in Côte d'Ivoire. The objective of this work is to evaluate the rate of some biochemical and physicochemical parameters and the health risks related to the consumption of soft drinks. The biochemical and physicochemical parameters were determined according to the standard SOXHLET technique, that of Kjeldhal and also that described by Dubois et al in1956. Potentially pathogenic and pathogenic germs were enumerated and researched according to reference methods described by AFNOR. The moisture content of the different beverages ranged from 3.9±0.05 to 3.2±0.05, and the sugar content from 26.06±2.05 to 5.96±1.60. For the acidity, the higher value was 0.93± 0.15 (Bissap juice) and the lowest was 0.64± 0.02 (Tamarind juice). For proteins, the high value was 44.15 ± 0.11 (Milk Mint Juice) and the low value was 38.15 ± 0.11 (Ginger Juice). As for dry matter, the highest value was found in ginger juice (44.76 ±0.02) and the lowest in bissap juice (40.96 ±0.01). Soft drinks sold in Williamsville schools contain such potentially pathogenic species as Staphylococcus aureus and Bacillus cereus with a wide range of loadings in the drinks. Escherichia coli was not identified. No Salmonella was observed in the different soft drinks analyzed. The presence of potentially pathogenic germs could pose a danger to school children.

Effect of propolis on Th2 and Th17 cells: interplay with EtxB- and LPS-treated dendritic cells

Dendritic cells (DCs) are antigen-presenting cells that drive the differentiation of T CD4+ cells into different profiles according to the nature of the antigen or immunomodulator. Propolis is a resinous product made by bees that has numerous pharmacological properties, including an immunomodulatory action. To assess whether propolis can modulate the activation of CD4+ T cells by stimulating DCs with heat-labile enterotoxin B subunit (EtxB) or lipopolysaccharide (LPS), we aimed to elucidate the mechanisms affected by propolis in the differential activation of T lymphocytes. Cell viability, lymphocyte proliferation, gene expression (GATA-3 and RORc), and cytokine production (interleukin (IL)-4 and IL-17A) were analyzed. Propolis, EtxB, and LPS induced a higher lymphoproliferation compared with the control. Propolis induced GATA-3 expression and, in combination with EtxB, maintained the baseline levels. Propolis alone or in combination with LPS inhibited RORc expression. EtxB alone and in combination with propolis increased IL-4 production. Propolis in combination with LPS prevented LPS-induced IL-17A production. These results opened perspectives for the study of biological events that may be favored by propolis by promoting Th2 activation or helping in the treatment of inflammatory conditions mediated by Th17 cells.

Attitudes and practices of travelers regarding COVID-19 vaccine and adverse reactions

Objective.In the context of the global COVID-19 pandemic, COVID-19 vaccines were made available to different countries. This study aimed to assess travelers' attitudes and practices toward the COVID vaccine and adverse events. Methods. A survey was conducted using a questionnaire from April 1 to June 30, 2021, among travelers who came for their COVID-19 test at the Institut Pasteur of Côte d'Ivoire.Results. A total of 527 travelers agreed to participate in this study, including 336 men and 161 women. Overall, 26% of respondents had already received their COVID-19 vaccine, while 76% of respondents responded they did not want to be vaccinated. The age of those most vaccinated (116) ranged from 25 to 64 years with a small proportion for those over 65 years (0.8%). Travelers (41) to France were the most vaccinated. All vaccinated persons (135) had a high level of education and were either Christian (89 persons), Muslim (45 persons) or animist (1 person). Adverse events related to the COVID vaccination were reported in seven individuals. These included muscle pain, fever and nausea. Conclusion.Negative attitudes towards vaccines are a major public health concern. In view of these results, for awareness raising, vaccination campaign may be focused on youthand people over 65 years of age. Public health messages containing information about vaccine safety should be tailored to address this vaccine hesitancy

The role of serum levels of vitamin D in children's muscle strength: A systematic review

This review aims to investigate the different levels of vitamin D and its role in muscle strength in healthy children and non-athletes. A search conducted in three databases (PubMed, Scopus, and Psycinfo) resulted in 655 articles, which were systematically analyzed and selected based on the following criteria: (a) original cross-sectional studies and clinical trials; (b) healthy children aged 5-11 years; (c) no language restriction or year of publication; and (d) studies that assessed the possible relationship between vitamin D levels and muscle strength. Six studies were included because they met all the inclusion criteria. According to the findings of this review, factors such as sex, skin color, and vitamin D supplementation early in life modulate the levels of vitamin D in the body, and there is a relationship between muscle strength and vitamin D levels. Interestingly, vitamin D supplementation is not always significantly associated with increased muscle grip strength. However, there is a scarcity of studies that aim to analyze the possible effects of different levels of vitamin D on muscle function and neuromuscular variables in physically inactive children and non-athletes without previously diagnosed disease. Further studies are warranted in the future to address the gap in the literature.

Reference values for biochemical analytes in feral sheep from Socorro Island, Revillagigedo Archipelago, Mexico / [Valores de referência para analitos bioquímicos em carneiros selvagens na Ilha Socorro, Arquipélago de Revillagigedo, México]

To establish reference values for biochemical analytes related to freshwater shortage adaptation, a total of 376 blood samples were collected from feral sheep at Socorro Island, Revillagigedo Archipelago. Year-round variation was assessed by sampling at the beginning of each season defined by the March equinox, June solstice, September equinox, and December solstice. The resulting data set was analyzed using Gaussian distribution and descriptive statistics. Confidence intervals of 95% were established. Analysis of variance was used to compare the mean values of each season. Total cholesterol, triglycerides, urea, albumin, total protein, sodium ion, anion gap, creatine kinase, arginine vasopressin, and aldosterone showed concentrations above the reference range for domestic sheep. Triglycerides, urea, albumin, sodium ion, and aldosterone showed concentrations within the reference range for domestic goats. Most biochemical analytes showed differences (P<0.05) between seasons, with the highest values occurring during winter, and the lowest during spring. Results could help improve the accuracy of metabolic profiles used as a tool for evaluating dehydration indicators, and to describe the physiological mechanisms employed by feral sheep to cope with seasonal availability of freshwater.(AU)

Para estabelecer valores de referência para analitos bioquímicos relacionados à adaptação da escassez de água doce, um total de 376 amostras de sangue foram coletadas de carneiros selvagens na ilha de Socorro, no arquipélago de Revillagigedo. A variação durante todo o ano foi avaliada por amostragem no início de cada estação definida pelo equinócio de março, solstício de junho, equinócio de setembro e solstício de dezembro. O conjunto de dados resultante foi analisado usando distribuição Gaussiana e estatística descritiva. Intervalos de confiança de 95% foram estabelecidos. A análise de variância foi usada para comparar os valores médios de cada estação. O colesterol total, triglicerídeos, ureia, albumina, proteína total, íon sódio, hiato aniônico, creatina quinase, arginina vasopressina e aldosterona apresentaram concentrações acima do intervalo de referência para carneiros domésticos. Triglicerídeos, ureia, albumina, íon sódio e aldosterona apresentaram concentrações dentro da faixa de referência para cabras domésticas. A maioria dos analitos bioquímicos apresentou diferenças (P<0,05) entre as estações, com os maiores valores ocorrendo no inverno e os menores na primavera. Os resultados podem ajudar a melhorar a precisão dos perfis metabólicos usados como uma ferramenta para avaliar os indicadores de desidratação e descrever os mecanismos fisiológicos empregados pelas carneiros selvagens para lidar com a disponibilidade sazonal de água doce.(AU)

This case report shows the successful treatment of “Oro-facial herpes” and its complication only through Ayurveda. In which, there will be closed grouped vesicles on an erythematous base in the dermatomal pattern, with burning type of pain. The condition in Ayurveda can be co- related to ‘Visarpa’. We present a case of 72-year, male, with sudden onset of edema over upper gums, with 3 to 4 vesicles over the left upper lip, left part of face within 2 days, along with reduced sensation to touch and temperature. The patient had redness, watering and burning sensation of left eye. Clinically the patient was diagnosed with “Oro- Facial Herpes”. As pitta dosha and raktadhatu vitiation was noticed the case was managed by Nitya pitta rechaka (cholegogue), the dravy’s with tikta, sheetaveerya and ruksha in nature. The patient showed improvement over 5 months of treatment from 10-Apr to 15-Aug-2018. The complaints of pain in the lesions reduced from 8 to 2, headache from 8 to 1 (VAS) and burning sensation reduced by 90%.

Prevalence of Rubella IgG Antibodies among Pregnant Women in Rivers State, Nigeria

Aim: Rubella virus is the cause of the communicable viral infection that can affect the foetus causing foetal loss or congenital rubella syndrome. Plasma samples from 180 pregnant women attending tertiary hospitals in River State, Nigeria were examined randomly to evaluate the prevalence of rubella virus (RubV) IgG antibodies.Study Design:Cross-sectional study.Place and Duration of Study:University of Port Harcourt Teaching Hospital (UPTH) and Braithwaite Memorial Specialist Hospital (BMSH) now Rivers State University Teaching Hospital (RSUTH) between September 2015 and August 2017 Methods: The sample of this study was composed of 180 pregnant women. ELISA was used to detect the RubV IgG antibodies andprevalence was correlated with sociodemographic factors.Results: The study result revered that 155(86.1%) were positive for RubV IgG while 25(13.9%) were negative for RubV IgG. Of the 90 samples examined from BMSH, 71(78.9%) were IgG-positive. From UPTH,84(93.3%) were positive for RubV IgG. The highest (100%) seropositivity for RubV IgG was found in age groups 39-43 years. No RubV IgG was recorded in age groups 44-48 years. Women in their third trimester had the highest prevalence of RubV IgG antibodies (94.7%). Those with secondary education had the highest prevalence of RubV IgG (93.4%). Vaccinated pregnant women had the highest prevalence (87.4%). Among the variables evaluated, education (p=0.023), occupation (p=0.040), marital status (p=0.001) and vaccination history (p=0.005) were the main correlates in this study.Conclusions: This study has shown evidence of immunity among expectant mothers in this study (86.1%) with 13.9% being vulnerable to rubella virus infection. Completion of adequate rubellavaccination along intensified surveillance of the vulnerable population remains the keystone for the control of congenital rubella syndrome in Nigeria

Características epizootiológicas da infecção natural pelo vírus da cinomose canina em Belo Horizonte / Natural canine distemper virus infection epizootiology characteristics in Belo Horizonte

O perfil epizootiológico da cinomose canina em Belo Horizonte é desatualizado e não alberga algumas características relevantes. Uma análise recente da distribuição do vírus em relação às características do hospedeiro e do meio ambiente associada aos principais sinais clínicos e achados laboratoriais são importantes para se adotarem medidas estratégicas para o controle da enfermidade. Objetivou-se, assim, determinar as características epizootiológicas da infecção pelo vírus da cinomose canina associada à variedade de sinais clínico-neurológicos e laboratoriais em Belo Horizonte, auxiliando no diagnóstico precoce da infecção e na diminuição das taxas de morbidade e mortalidade da doença. A avaliação do perfil epizootiológico de 90 cães revelou que a doença é mais frequente em animais adultos (um a seis anos de idade) e que não receberam vacinas conforme recomendado pelos protocolos. Os sinais clínicos extraneurais e neurais foram variados, com predomínio para manifestações gastrentérica e respiratória, mioclonia e déficit motor, respectivamente. O exame do fluido cérebro-espinhal demonstrou predomínio de proteinorraquia associada à pleocitose linfocítica. O teste de imunocromatografia para pesquisa de antígeno com amostras do fluido cerebroespinhal foi eficaz para identificar a doença em pacientes com sinais neurológicos, diferentemente das amostras do swab conjuntival, que não devem ser utilizadas.(AU)

The epizootiology profile of canine distemper in Belo Horizonte is outdated and does not harbor some important characteristics. A recent analysis of the virus distribution in relation to host and environmental characteristics associated with the main clinical signs and laboratory findings are important for adopting strategic measures to control the disease. The aim of this study was to determine the epizootiology characteristics of canine distemper virus infection associated with a variety of clinical and neurologic signs and laboratory findings in Belo Horizonte, helping to detect early infection and reduce morbidity and mortality rates. The evaluation of the epizootiology profile of 90 dogs revealed that the disease is more frequent in adult animals (1-6 years of age) and did not receive vaccines as recommended by the protocols. Extra neural and neural clinical signs were varied, with predominance for gastrointestinal and respiratory manifestations and myoclonus and motor deficit, respectively. Examination of the cerebrospinal fluid of 16 dogs showed a predominance of increase protein associated with lymphocytic pleocytosis. The immunochromatography test for antigen screening with samples of cerebrospinal fluid in 76 animals with neurological signs was effective in identifying the disease, unlike conjunctival swab samples, which should not be used.(AU)

Yeast culture in the diet of feedlot steers: performance, carcass traits and feeding behavior / Cultura de leveduras na dieta de novilhos confinados: desempenho, características da carcaça e comportamento ingestivo

This study aimed to evaluate the performance, apparent digestibility of diet, ingestive behavior which occurred in two moments, carcass traits, being evaluated constituent and non-carcass components, and also the effect the yeast culture could promote in the peripheral temperature of rumen, hull and body temperature. The diets consisted of a constant ratio of 50% forage (maize silage) and 50% concentrate. Thirty-six steers, ½ Angus Nelore, with average age of 11 months and average initial body weight of 339.5±10kg were used in the experiment. The inclusion of yeast culture promoted a higher daily dry matter intake (8.83 vs 9.35kg day-1) and, consequently, a better daily weight gain (1,143 vs. 1,325kg day-1) in the initial feedlot phase, with no difference in other periods. The apparent digestibility of the diet containing yeast culture was higher than the control diet (69.69 versus 68.32%, respectively), and its use did not interfere with the feeding behavior of the animals. Based on our findings, supplementation with yeast culture may bring positive results in the initial feedlot phase.(AU)

O objetivo deste estudo foi avaliar o desempenho; a digestibilidade aparente da dieta; o comportamento oral ingestivo, o qual ocorreu em dois momentos, as características de carcaça, sendo avaliados componentes integrantes e não integrantes da carcaça; bem como o efeito que a cultura de leveduras pudesse promover perante a temperatura periférica de rúmen, casco e temperatura corpórea, sendo aferida por meio da temperatura retal. As dietas foram constituídas em uma constante relação de 50% de volumoso (silagem de milho) e 50% de concentrado. Utilizaram-se no experimento 36 novilhos, ½ sangue Angus Nelore, com idade média de 11 meses e peso vivo médio inicial de 339,5 ± 10kg. O uso de cultura de leveduras promoveu maior consumo diário de matéria seca (8,83 contra 9,35 kg dia-1) e consequentemente melhor ganho de peso diário (1,143 contra 1,325kg dia-1) na fase inicial do confinamento, não havendo diferença nos demais períodos. A digestibilidade aparente da dieta que continha cultura de leveduras foi superior à da dieta controle (69,69 contra 68,32%, respectivamente), e seu uso não interferiu no comportamento ingestivo dos animais. Com base nos resultados do presente estudo, a suplementação com cultura de leveduras pode trazer resultados positivos na fase inicial de confinamento.(AU)

Cancer du sein triple négatif chez la femme enceinte : le pronostic est-il si mauvais dans le contexte africain ?

Le cancer du sein triple négatif est un groupe de carcinome du sein caractérisé par le manque d'expression des récepteurs hormonaux aux oestrogènes et à la progestérone (RE, RP) et HER2. Cette forme se caractérise également par son agressivité, un faible taux de survie et l'absence de thérapies ciblées. Dans cemanuscrit, nous en rapportons deux cas de survenant chez des femmes enceintes ayant bénéficié d'une chirurgie basée sur des mastectomies plus curage axillaire suivie d'une chimiothérapie et radiothérapie adjuvantes. Les deux évolutions ont été marquées par la survenue de métastases cérébrales. À travers ces cas, nous décrivons en mettant un accent sur les caractéristiquesclinique et le mauvais pronostic du cancer du sein triple négatif pendant la grossesse. Nous soumettons également une brève revue de la littérature sur cette situation pendant la grossesse

Performance, carcass characteristics and ingestive behavior of steers fed with silages of different maize hybrids / Desempenho, características da carcaça e comportamento ingestivo de novilhos alimentados com silagens de diferentes híbridos de milho

The objective of this study was to evaluate the performance, carcass characteristics and ingestive behavior of feedlot steers fed with three maize hybrids: Maximus VIP3, Defender VIP and Feroz VIP. The experiment lasted 112 days, weighing animals four times, every 28 days. The experimental diets were formulated and constituted by maize silage and pelletized ration in a 50:50 ratio (dry basis). Regardless of the hybrid used, there was an increase in the intake of dry matter with the advance in feedlot evaluation period (9.15, 9.14, 9.35 and 9.59kg day-1, in the first, second, third and fourth weighing, respectively). The type of maize hybrid silage influenced weight gain of animals differently, with a final mean of 1.413kg for animals fed with Maximus VIP3, 1,375kg for those fed with Defender VIP and 1,184kg for those fed with Feroz VIP. The animals fed with Feroz VIP hybrid silage showed higher carcass gain efficiency and were more active in the number of times they went to the feeder. Although the three evaluated hybrids resulted in good animal performance, the carcass characteristics did not change; nevertheless, the hybrid Maximus VIP3 is recommended for its superior bromatological composition.(AU)

O objetivo deste trabalho foi avaliar desempenho, características da carcaça e comportamento ingestivo de novilhos terminados em confinamento alimentados com silagens dos híbridos de milho: Maximus VIP3, Defender VIP e Feroz VIP. O experimento teve duração de 112 dias, sendo quatro pesagens a cada 28 dias. As dietas experimentais foram formuladas e constituídas por silagem de milho e ração peletizada em proporção de 50:50, na base seca. Independentemente do híbrido utilizado, houve aumento conforme avanço na fase de terminação (9,15; 9,14; 9,35 e 9,59kg dia-1, na primeira, segunda, terceira e quarta pesagens, respectivamente). A distinção da silagem de milho determinou diferença no ganho de peso dos animais, com média final de 1,413kg para os animais tratados com Maximus VIP3, 1,375kg para os tratados com Defender VIP e 1,184 para aqueles alimentados com Feroz VIP. Os animais alimentados com silagem do híbrido Feroz VIP apresentaram maior eficiência de ganho de carcaça e foram mais ativos ao número de vezes em ir ao comedouro. Apesar dos três híbridos avaliados proporcionarem bons resultados relacionados ao desempenho animal, as características da carcaça não sofreram alterações; mesmo assim, recomenda-se o híbrido Maximus VIP3 por sua superioridade bromatológica.(AU)

Management of rectal prolapse (Guda Bhramsa) through Kshara Karma (chemical cauterisation): a case study / Manejo do prolapso retal (Guda Bhramsa) usando Kshara Karma(cauterização química): um estudo de caso

Abstract Rectal Prolapse is a condition where the rectum protrudes beyond the anus. The explanation of this condition can be traced back to ancient Ayurveda text like Susruta Samhita, Ebers Pappyrus of 1500 B.C., etc. The exact cause of rectal prolapse is unclear but it is predominant on female gender and on people having constipation, previous anorectal surgeries etc. Both partial and complete varieties of rectal prolapse are extremely debilitating because of the discomfort of the prolapsing mass and variety of symptoms like rectal bleed, intermittent constipation or fecal incontinence. Although, diverse modalities of surgical management of rectal prolapse are present, no single optimal procedure is proved and the choice of operation is determined by the patient's age, sex, degree of incontinence, operative risk, as well as by the surgeon's experience. In Ayurveda, Guda Bhramsa (Rectal prolapse) is explained by Acharya Susruta under Kshudra Rogas (chapter of minor diseases) and has elaborated it's conservative management very beautifully. In this case, a female with partial rectal prolapse was treated with Kshara application and managed without complications. So, Kshara application can be a safe and effective alternative for the management of rectal prolapse.

Resumo O prolapso retal é uma condição em que o reto se projeta para além do ânus. A explicação desta condição foi relatada em antigos textos Ayurveda como Susruta Samhita e Ebers Pappyrus, datados de 1500 aC. A causa exata do prolapso retal não é clara, mas essa condição é predominante no sexo feminino e nas pessoas com constipação e histórico de cirurgias anorretais anteriores. Tanto o prolapso retal parcial quanto total são extremamente debilitantes devido ao desconforto da massa prolapsante e da variedade de sintomas como sangramento retal, constipação intermitente ou incontinência fecal. Embora diversas modalidades de tratamento cirúrgico para corrigir o prolapso retal tenham sido relatadas na literatura, nenhum procedimento é consensual; a escolha da operação é determinada pela idade, sexo, grau de incontinência, risco operatório e experiência do cirurgião. Na Ayurveda, Guda Bhramsa (prolapso retal) é explicado por Acharya Susruta no Kshudra Rogas (capítulo de doenças menores) e seu manejo conservador é descrito de forma bastante completa. No presente caso, uma paciente do sexo feminino com prolapso retal parcial foi tratada com aplicação de Kshara e administrada sem complicações. Assim, a aplicação de Kshara pode ser uma alternativa segura e eficaz para o manejo do prolapso retal.
