    Introdução: A internação hospitalar no pós-operatório oferece ao paciente condições de recuperação rápida e pode evitar possíveis complicações decorrentes da cirurgia. Objetivo: Determinar o número de indicações e o tempo de permanência em internação durante o período pós-operatório imediato de pacientes submetidos a procedimentos cirúrgicos diversos. Método: Foram avaliados em um hospital público da região central da cidade de São Paulo - SP, pacientes que se submeteram à cirurgias de diversas especialidades entre janeiro e março de 2011. Resultados: Dos 10 pacientes acompanhados, 8 receberam indicação de internação no período pós-operatório e 2 receberam alta logo após o procedimento cirúrgico. Troca de valva cardíaca, desobstrução intestinal e cirurgia bariátrica foram, nesta sequência, os procedimentos que demandaram maior tempo de internação. Conclusão: A pré-admissão do paciente com necessidades cirúrgicas é muito importante no prognóstico dos mesmos e pode estar intimamente relacionada com a evolução do seu quadro clínico. Pacientes com mais comorbidades tendem a apresentar prognóstico mais reservado, o que per se aumenta o tempo de internação e, consequentemente, os custos e os riscos da prolongada permanência em ambiente hospitalar.DOI: 10.5585/rgss.v1i1.

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

    Morphological and functional markers of tubulointerstitial lesion in glomerulopathies

    Tem havido um interesse crescente no estudo do papel da lesao tubulo¬ intersticial na progressao das doencas glomerulares para insufiCiência renal. O componente tubulo-intersticial parece ter uma influencia decisiva no prognostico das doencas renais. O diagnostico precoce das lesoes tubulares proximais pode ser feito pela presenca de niveis anormais de proteinas de baixo peso molecular na urina. Casuistica e metodos: Avaliamos retrospectivamente 100 casos de glomerulopatias com o objetivo de estabelecer o perfil dos niveis urinarios da proteina transportadora do retinol (RBPur) em tais doencas e a possivel associacao com marcadores histologicos de lesao tubulo-intersticial em biopsia renal. A determinacao da RBPur e a biopsia renal ocorreram em momentos proximos, assim como as determinacoes de outros parametros laboratoriais relacionados a avaliacao da funcao renal. O estudo histologico incluiu a graduacao da lesao tubulo-intersticial por microscopia optica e morfometria, usando-se para a ultima coloracao previa pelo vermelho de picrosirius. Resultados: Houve predominio do sexo masculino, de adultos jovens e brancos e de glomerulopatias nao-proliferativas. A probabilidade de ter RBPur anormal foi mais elevada entre pacientes com doencas glomerulares que apresentavam um componente proliferativo predominante (2x, p = 0,163), creatinina se rica basal >1,2 mg/dL (3,5x, p = 0,008), clearance de creatinina <70 mL/min (3,8x, p = 0,006), fibrose intersticial severa (10x, p = 0,042) e atrofia tubular severa (9,6x, P = 0,052). Na analise multivariada, apenas creatinina serica e clearance de creatinina, incluidos separadamente em dois moderas diferentes, associaram-se de forma independente a RBPur. A creatinina serica, o clearance e a RBPur foram posteriormente introduzidos em modelo de regressao de Cox, e somente a RBPur revelou-se um fator prognostico nao-dependente de tempo para sobrevida livre de insufiCiência renal (risco de insufiCiência renal para RBPur anormal foi de 9x, p = 0,035). Conclusao: Concluimos que a determinacao de RBPur, refletindo a presenca de lesao tubulo-intersticial transitoria ou permanente tem relevancia prognostica na progressao das glomerulopatias para insufiCiência renal; os marcadores histologicos e morfometricos avaliados, por sua vez, tiveram uma correlacao fraca com a evolucao clinica de tais pacientes. Consequentemente, o marcador funcional de lesao tubulo-intersticial, RBPur, foi mais adequado para determinar o prognostico das doencas glomerulares do que as analises histologica e morfometrica das biopsias renaisBV UNIFESP: Teses e dissertaçõe

    Background: Early diagnosis of proximal tubular lesions can be achieved by detecting abnormal levels of low molecular weight proteins in urine. Material and Methods: 100 cases of glomerulopathies were retrospectively studied to establish the profile of urinary levels of retinol-binding protein (urRBP) and their correlation with histological markers of tubulointerstitial lesions in renal biopsies. the histological study included staining with picrosirius red. Results: Non-proliferative glomerulopathies, male sex, white race and young adults were predominant. the chance of abnormal urRBP occurring was higher among patients with a predominant proliferative component, baseline serum creatinine >1.2 mg/dl (p = 0.008), creatinine clearance <70 ml/min (p = 0.006), and severe interstitial fibrosis (p = 0.042). in multivariate analysis, only serum creatinine and creatinine clearance were independently associated to urRBP, and only urRBP was a time-independent prognostic factor for survival without renal failure ( risk of renal failure: 9 !). Conclusion: Our study suggests that urRBP determination is prognostically relevant in the progression of glomerulopathies; on the other hand, the evaluated morphometric markers correlated poorly with the clinical outcome of these patients. Consequently, urRBP determination, as a functional marker of tubulointerstitial damage, was more appropriate for determining the prognosis of glomerular diseases than the morphometric analysis of renal biopsies.
