Cryptosporidium SP in HIV-infected individuals attending a Brazilian University Hospital J. Venom. Anim. Toxins incl. Trop. Dis.
Langoni-Júnior,G.; Souza,L. R..
The aim of the current work was to evaluate the occurrence of Cryptosporidium sp in AIDS patients in a region of São Paulo State, Brazil. Patients were divided into groups according to CD4+ T lymphocyte count and use of potent antiretroviral treatment. Two hundred and ten fecal samples from 105 patients were fixed in 10% formalin and subjected to centrifuge formol-ether sedimentation. Slides were stained with auramine and confirmed by modified Ziehl-Neelsen. Cryptosporidiosis occurrence was 10.5% with no relationship among gender, age or the presence of diarrhea. The number of oocysts in all samples was small, independent of CD4+ T lymphocyte count, HIV plasma viral load, and presence of diarrhea. These results may be due to the reduced prevalence of...

Aerobic training modulates T cell activation in elderly women with knee osteoarthritis BJMBR
Gomes,W.F.; Lacerda,A.C.R.; Brito-Melo,G.E.A.; Fonseca,S.F.; Rocha-Vieira,E.; Leopoldino,A.A.O.; Amorim,M.R.; Mendonça,V.A..
Osteoarthritis of the knee (kOA) is a disease that mainly affects the elderly and can lead to major physical and functional limitations. However, the specific effects of walking, particularly on the immune system, are unknown. Therefore, this study aimed to analyze the effect of 12 weeks of walking (3×/week) on the leukocyte profile and quality of life (QL) of elderly women with kOA. Sixteen women (age: 67±4 years, body mass index: 28.07±4.16 kg/m2) participated in a walking program. The variables were assessed before and after 12 weeks of training with a progressively longer duration (30–55 min) and higher intensity (72–82% of HRmax determined using a graded incremental treadmill test). The QL was assessed using the Medical Outcomes Study 36-Item Short...
