Background and Aims Hyperprolactinemia is a hormonal disorder associated with many diseases, including chronic kidney disease (CKD). Some studies have shown that serum prolactin (PRL) levels increase as CKD progresses, due to decreased renal clearance and increased production. This prolactin retention leads to inhibition of gonadotropic hormone production, and testosterone deficiency in male patients with CKD. Thus, this study aimed to evaluate PRL levels in male patients with different stages of CKD and its association with clinical and laboratory characteristics, strength, sexual dysfunction, and quality of life. Method This is a transversal study conducted in a tertiary hospital in southern Brazil. Patients with CKD stage IV and V were included and divided into three groups: 1) stage IV; 2) non-dialysis-dependent stage V and; 3) dialysis-dependent stage V (VD). Patients with prescribed hormone therapy were excluded. PRL, creatinine, testosterone, estradiol, albumin, SHBG, LH, and FSH levels were measured. Free testosterone was estimated by the Vermeulen equation. Patients were also evaluated for strength and musculoskeletal function through the “handgrip strength” test. For evaluation of the quality of life and sexual dysfunction, validated questionnaires were applied: AMS (Aging Male's Symptoms Scale), ADAM (Androgen Deficiency in the Aging Male) and SF-36 Health. Results In this study, 164 patients were included (IV=75; V=41; VD=48). The mean age was 64 [55-71] years and BMI 26,9 [23,3-30,04] kg/m2. The dialysis-dependent group had higher prevalence of hyperprolactinemia (22,6% vs. 49% vs. 66%, p<0,001), higher PRL (13,4 vs. 19,43 vs. 26,13, p<0,001) and estradiol (25,6 vs. 24,4 vs. 30,5, p=0,041). PRL levels were positive correlated with CKD stage (rs=0,482, p<0,001) and creatinine (rs=0,467, p<0,001) and negative correlated with testosterone (rs=-0,286, p<0,001) and free testosterone levels (rs=-0,307, p<0,001). There was no difference in PRL levels between hemodialysis and peritoneal dialysis (p=1,000). Analyzes related to the association of PRL levels with strength, quality of life, and sexual dysfunction are still being analyzed. Conclusion Hyperprolactinemia is associated with the severity of CKD, with a higher prevalence in dialysis patients. The relation of PRL levels with strength, quality of life, and sexual dysfunction are being evaluated.
SummaryThis study was conceived to evaluate the feasibility of a thoracoscopic technique intended for partial pericardiectomy in horses and how cardiac volumes are influenced by such procedure in an immediate and mid‐term perspective. Thoracoscopic pericardiectomy, which is known as a minimally invasive technique, was performed in six healthy horses. Echocardiographic evaluation was performed in every horse at different times, before and after the procedure. According to the area‐length method, the following parameters were evaluated: maximum left atrial volume, minimum left atrial volume, left ventricular volume in systole and left ventricular volume in diastole. These variables were used to calculate the ejection fraction of the left atrium and left ventricle. After 28 days, repeated thoracoscopy was performed to inspect the thoracic cavity. Pericardiectomy was successfully performed in all horses, with post‐operative complication documented in only one animal. After 28 days, adhesion was observed in two animals, located between the epicardium and the thoracic wall, without however impairing cardiac function. Pericardial window was broad and well delimited in all horses, without impairing cardiac function. The thoracoscopic pericardiectomy was feasible in all horses. Although a mild reduction in cardiac volumes was documented in the first 72 h after surgery, the procedure did not impair cardiac filling and emptying in the mid‐term perspective. Future studies are warranted to investigate how this technique performs in horses with pericardial diseases.
Introdução: O objetivo principal é avaliar o comportamento alimentar de recémnascidos (RN) pequenos (PIG) e grandes (GIG) para a idade gestacional através de questionário específico e comparar com RN adequados para a idade gestacional (AIG) com 1 mês de vida. Métodos: É um estudo de coorte, cuja primeira fase consistiu na realização de uma entrevista com mães que tiveram seus filhos a termo no Hospital de Clínicas de Porto Alegre. Dados perinatais foram coletados de prontuários eletrônicos. Na segunda fase do estudo, após 1 mês do nascimento, foi aplicado o Questionário sobre Comportamento Alimentar do Bebê (Baby Eating Behaviour Questionnaire, BEBQ) através de contato telefônico. Resultados: Foram avaliados 126 RN (43 AIG, 43 PIG e 41 GIG). Foi observada uma maior escolaridade em mães de RN PIG (p=0,004) e uma menor prevalência de aleitamento materno exclusivo até a alta hospitalar em RN GIG (p=0,002). A análise de variância não encontrou diferença significativa entre os grupos em relação aos domínios do BEBQ, mesmo quando corrigidos por sexo do RN. Conclusão: O estudo demonstrou que alterações do comportamento alimentar ainda não estão presentes com 1 mês de vida, sugerindo que não são inatas, e sim desenvolvidas com o passar do tempo. O estudo está limitado a avaliações de crescimento baseadas em registros de terceiros.
RESUMOFoi encaminhado ao setor de Patologia Animal da Universidade Federal de Uberlândia um caprino, macho sem raça definida, adulto, proveniente de uma caprinocultura localizada no município de Uberlândia. O animal havia morrido após manifestações de sinais clínicos respiratórios e intolerância a exercícios físicos. O exame necroscópico revelou artéria aorta rígida, com intima de aspecto rugoso, espessamento da parede e presença de placas irregulares, brancacentas e elevadas, que rangiam ao corte. Microscopicamente observou-se acúmulo de substância basofílica, granular amorfa na camada média do vaso. Os achados macro e microscópicos foram compatíveis com calcinose enzoótica. No Brasil central essa enfermidade tem sido associada à ingestão de plantas tóxicas com ação calcinogênica. Porém, a espécie de planta responsável pela calcinose não tem sido identificada. A propriedade de origem do caprino está localizada em região de cerrado, com solo pouco fértil. Um dos fatores que pode estar associado a ocorrência de calcinose enzoótica, é a presença de pastos degradados com plantas daninhas. A calcinose enzoótica em ruminantes na região de Uberlândia se constitui em desafio no sentido de se descobrir as plantas que podem estar causando a enfermidade. Este relato ressalta a necessidade de estudos epidemiológicos, clínicos, patológicos e experimentais que ajudem a identificar plantas calcinogênicas na região, pois há escassez de tais estudos no cerrado. Como forma de prevenção da calcinose na região pode ser recomendado o cuidado com pastagens degradadas e combate a plantas daninhas.
