Is Metabolic syndrome truly a risk factor for male lower urinary tract symptoms or just an epiphenomenon?

To define whether the association of male lower urinary tract symptoms (LUTS) and metabolic syndrome (MS) is real or simply an epiphenomenon, 490 male adults (mean age 58 ± 9 years) underwent International Prostate Symptom Score (IPSS), physical and prostate digital examinations, blood analysis, and urinary tract transabdominal ultrasound with prostate volume measurement. Mild, moderate, and severe LUTS were found in 350 (71.4%), 116 (23.7%), and 24 (4.9%) patients, respectively. MS was present in 198 (40.4%) patients, representing 37.4% (131 of 350) of those with mild LUTS, 46.5% (54 of 116) of those with moderate, and 54.1% (13 of 24) of those with severe. The odds ratio of MS having moderate or severe LUTS was 2.1. MS was more common in older age, higher body mass index, and larger prostate size. Moderate and severe LUTS were more frequent in older age, lower levels of high density cholesterol, and higher blood pressure. Older age and body mass index had significant relative risk for lower urinary tract symptoms and only age remained independent factor for LUTS on multivariate analysis. Our results suggest that the association of male LUTS, prostate volume, and MS might be coincidental and related to older age2014sem informaçã

Comparative and Prospective Analysis of Three Different Approaches for Live-Donor Nephrectomy

PURPOSE: Living donor nephrectomy is usually performed by a retroperitoneal flank incision. Due to the significant morbidity and long recovery time for a flank incision, anterior extra peritoneal sub-costal and transperitoneal video-laparoscopic methods have been described for donor nephrectomy. We prospectively compare the long-term results of donors as well as functional recipients submitted to these three approaches. MATERIALS AND METHODS: A total of 107 live donor renal transplantations were prospectively evaluated from May 2001 to January 2004. Donors were compared with regard to operative and warm ischemia time, postoperative pain, analgesic requirements, and complications. Recipients were compared with regard to graft function, acute cellular rejection, surgical complications, and graft and recipient survival. RESULTS: The mean operative and warm ischemia times were longer in the video-laparoscopic group (p<0.001), whereas patients of the flank incision group presented more postoperative pain (p=0.035), required more analgesics (p<0.001), had longer hospital stays (p<0.001), and suffered more pain on the 90th day after surgery (p=0.006). In the sub-costal and flank incision groups, there was a larger number of paraesthesias and abdominal wall asymmetries (p<0.001). Recipient groups were demographically comparable and presented similar acute tubular necrosis incidence and delayed graft function. The incidence of acute cellular rejection was higher in the video-laparoscopic and flank incision groups (p=0.013). There was no difference in serum creatinine levels, surgical complications, or recipient or graft survival between groups. CONCLUSIONS: The video-laparoscopic and sub-costal approaches proved to be safe, and to provide donor advantages relative to the flank incision approach. Among recipients, the complication rate, graft survival, and recipient survival were similar in all groups

O papel do transplante de célula-tronco hematopoética no diabetes mellitus tipo1

In this review, we present 1) scientific basis for the use of high dose immunosuppression followed by autologous peripheral blood hematopoietic stem cell transplantation for newly diagnosed type 1 diabetes mellitus, 2) an update of clinical and laboratory outcomes in 21 patients transplanted at the University Hospital of the Ribeirão Preto Medical School, University of São Paulo, Brazil, including 6 relapses in patients without previous ketoacidosis and 3) a discussion of future prospectives of cellular therapy for type 1 diabetes mellitus.Nesta revisão, são apresentadas: 1) as bases científicas para o uso de imunossupressão em alta dose seguida de transplante autólogo de células-tronco hematopoéticas do sangue periférico no diabete melito do tipo 1 recém-diagnosticado; 2) uma atualização da evolução clínica e laboratorial de 21 pacientes transplantados no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto, da Universidade de São Paulo, Brasil, incluindo recaídas em seis pacientes transplantados sem cetoacidose prévia; e 3) uma discussão das perspectivas futuras de terapia celular no diabete melito do tipo 1

Cell therapy in diabetes mellitus

Nesta revisão são discutidas várias alternativas de regeneração do conjunto de células produtoras de insulina do pâncreas, usando células-tronco embrionárias do cordão umbilical e adultas, e o trabalho que está sendo realizado em nosso grupo de pesquisas utilizando imunossupressão em altas doses combinada com a infusão de células-tronco hematopoéticas autólogas em diabete do tipo 1 recém-diagnosticado.In this review, we discuss several alternatives for the regeneration of the pool of insulin-producing cells by the pancreas using embryonic, cord blood or adult stem cells and the work being carried out by our research group using high dose immunosuppression with autologous hematopoietic stem cells in newly diagnosed type 1 diabetes mellitus

The mammals of Angola

Scientific investigations on the mammals of Angola started over 150 years ago, but information remains scarce and scattered, with only one recent published account. Here we provide a synthesis of the mammals of Angola based on a thorough survey of primary and grey literature, as well as recent unpublished records. We present a short history of mammal research, and provide brief information on each species known to occur in the country. Particular attention is given to endemic and near endemic species. We also provide a zoogeographic outline and information on the conservation of Angolan mammals. We found confirmed records for 291 native species, most of which from the orders Rodentia (85), Chiroptera (73), Carnivora (39), and Cetartiodactyla (33). There is a large number of endemic and near endemic species, most of which are rodents or bats. The large diversity of species is favoured by the wide range of habitats with contrasting environmental conditions, while endemism tends to be associated with unique physiographic settings such as the Angolan Escarpment. The mammal fauna of Angola includes 2 Critically Endangered, 2 Endangered, 11 Vulnerable, and 14 Near-Threatened species at the global scale. There are also 12 data deficient species, most of which are endemics or near endemics to the countryinfo:eu-repo/semantics/publishedVersio
