Maximum oxygen uptake (V̇O2max) equations from developed countries are inaccurate for developing countries. Accordingly, we aimed to develop equations to predict treadmill V̇O2max over time based on variables other than exercise test in adults from the USA and Brazil undergoing cardiopulmonary exercise testing (CPET). We analyzed data from 2,170 adults who underwent two CPETs (1,307 men; 20-85 years) from the USA (n=1,880) and Brazil (n=290) with a second test after 2.

Article Synopsis
  • Salmonella spp. cause a range of diarrheal diseases and pose a public health threat, with this study focusing on the therapeutic effects of the yeast Saccharomyces cerevisiae CNCM I-3856 in mice infected with Salmonella Typhimurium.
  • The study found that mice treated with the yeast showed reduced mortality and weight loss compared to control mice, suggesting S. cerevisiae's potential benefits in managing Salmonella infections.
  • The yeast improved immune responses, reduced intestinal permeability, and lowered inflammation, leading to less severe liver and intestinal damage, indicating its promising role as a therapeutic agent against Salmonella-induced infections.

Background: Simultaneous liver-kidney transplantation is indicated for patients with concomitant end-stage liver disease and end-stage renal disease. The traditional technique involves separate implantations of the liver and the kidney. In the en bloc approach, the liver is recovered en bloc with the right kidney and the donor renal artery is anastomosed to the donor splenic artery.

Disorders of gastrointestinal motility are the major physiologic problem in chagasic megacolon. The contraction mechanism is complex and controlled by different cell types such as enteric neurons, smooth muscle, telocytes, and an important pacemaker of the intestine, the interstitial cells of Cajal (ICCs). The role of ICCs in the progression of acute and chronic Chagas disease remains unclear.

Background: Liver adenomatosis is characterized by multiple adenomas diffusely distributed throughout the liver parenchyma. Studies addressing liver transplantation for those cases are scarce, and the criteria used to indicate transplantation are still debatable.

Objective: To report a single-center experience of liver transplantation for diffuse adenomatosis.
