Introduction: Sarcopenia has been associated with increased morbidity and mortality in older people. However, there is still no consensus about the best diagnostic criteria for it.Objective: This study aimed to evaluate different diagnostic criteria of sarcopenia and their relationship with muscle strength and functional capacity. Methods: A cross-sectional study was carried out in Santa Maria-RS, Brazil. Body composition was measured by dual-energy X-ray absorptiometry (DXA). Physical performance was evaluated by the Timed-get-up-and-go test (TGUG). Muscle strength was measured with a handgrip dynamometer. The proposed criteria of sarcopenia were evaluated as follows: A) appendicular lean mass index (aLM/ht 2 ), cutoffs 5.5 kg/m 2 , 2SD, 10 th percentile, and 20 th percentile of young reference; B) a linear regression model was used to adjust appendicular lean mass (aLM) for both height and fat mass, cutoff 20 th percentile of elderly. Results: In total, 104 women agreed to participate in the research, 39 young (20 to 40 years) and 65 elderly (over 60 years). The prevalence of sarcopenia varied from 0% to 17.2% according to the diagnostic criteria. Regarding muscle strength, the aLM/ht 2 cutoff 10 th percentile was the criterion with greater area under the ROC curve. However, there were no criteria with an area under the ROC curve greater than 0.5 when TGUG was the outcome. The reclassification showed that the criterion B reclassified 66.7% with normal grip strength as sarcopenic. Conclusion: Of these criteria, aLM/ht 2 cutoff 10 th percentile had stronger correlation with muscle strength.

A agenesia da veia cava inferior é uma anomalia congênita rara, que foi recentemente identificada como um importante fator de risco para o desenvolvimento e a recorrência de trombose venosa profunda de membros inferiores em jovens. O objetivo deste trabalho foi relatar o caso de uma paciente que apresentou trombose venosa profunda dois meses após a realização de cirurgia de varizes. A angiotomografia computadorizada demonstrou a presença de anomalia venosa complexa com ausência da veia cava inferior.

A doença renal isquêmica ou nefropatia isquêmica relacionada à doença renovascular pode evoluir de forma rápida e progressiva para a insuficiência renal crônica. É fundamental a identificação e o tratamento precoces desta condição clínica, prevenindo a ocorrência de doença renal em estágio terminal, com consequente necessidade de terapia de substituição renal. Há uma década, o controle da hipertensão renovascular era o objetivo primário no manejo de pacientes com doença renovascular. Atualmente, a meta está dirigida principalmente para a estabilização e a melhora da função renal, além do controle dos níveis pressóricos.
