ReviewAccuracy of ultrasound to detect thrombosis in pregnancy: A systematic review.
To determine the diagnostic accuracy of ultrasound to detect deep--vein thrombosis in pregnant patients. ⋯ Accuracy of ultrasonography to diagnose deep-vein thrombosis in pregnant women was not determined due to the absence of data yielding positive results. Further studies of low risk of bias are needed to determine the diagnostic accuracy of ultrasonography in this clinical scenario.

ReviewHyperferritinemia in patients with nonalcoholic fatty liver disease.
In liver diseases, hyperferritinemia (HYF) is related to injured cells in acquired and genetic conditions with or without iron overload. It is frequent in patients with nonalcoholic fatty liver disease (NAFLD), in which it is necessary to define the mean of HYF to establish the better approach for them. The present study evaluated the significance of elevated ferritin in patients with NAFLD and steatohepatitis (NASH). ⋯ Hyperferritinemia in patients with NAFLD/NASH is associated more frequently with hepatocellular injury than hemochromatosis. These data suggest the relevance to evaluate carefully HYF in patients with NAFLD/NASH to establish appropriate clinical approach.

ReviewDialectics of a medical provision policy in priority areas in Brazil.
The people living in vulnerable areas that are difficult to access in Brazil represent a portion of the population that has proven very sensitive to lack of medical and health services. The government, seeking to solve the situation urgently, implemented the More Doctors Program [Programa Mais Médicos, in the Portuguese original] in 2013. ⋯ The regional inequalities of concentration and dispersion of physicians, showed by studies on medical demography in Brazil, stem from several factors, including the lack of a career path and working conditions. There is no point in having physicians if they do not have safe and ethical conditions to establish the diagnosis and a treatment plan, as well as to monitor the rehabilitation of the patient.

The effectiveness of the treatment of chronic diseases depends on the participation of the patient, influenced by different sociocultural factors, which are not fully recognized by the treatment routine. ⋯ The improved adherence to chronic treatment of ischemic heart disease depends on the establishment of effective flows for referral and counter-referral from one care unit to another, relevant information and clarification of the questions for the patients and the attention of health professionals to the many social and cultural factors involved in treatment adherence. New research should be focused on educational groups by integrated multidisciplinary teams in order to share treatment decisions, thereby increasing the patient's commitment to his own health.

Obesity refers to the accumulation of fatty tissues and it favors the occurrence of oxidative stress. Alternatives that can contribute to body weight reduction have been investigated in order to reduce the production of reactive oxygen species responsible for tissue damage. The aim of the current study was to assess whether the oxidant and antioxidant markers of obese women before and after bariatric surgery were able to reduce oxidative damage. ⋯ Body weight influences the production of reactive oxygen species. Bariatric surgery, combined with weight loss and vitamin supplementation, reduces cellular oxidation, thus reducing tissue damage.
