This article analyzes the behavior of surface finish and pressing time in glued pieces of eucalyptus wood. The importance of the study lies in verifying the influence of two variables (surface finish and pressing time) on the gluing of wood pieces for the furniture industry over time. For this purpose, the quality of adhesion of Eucalyptus urograndis wood pieces with polyvinyl acetate adhesive and the behavior of the wood to shear in the glue line are evaluated. It was necessary to produce test specimens according to the ABNT-NBR 7190 standard; three different surface finishes were evaluated on the faces to be adhered and three different cold pressing times, a variable that has not been analyzed in previous studies. It was possible to determine the shear resistance in the glue line and also to observe the percentage of wood failure when performing the destructive test on the test specimen 1 year after being glued. The highest shear strength was obtained for test specimens without surface finish and with a pressing time of 24 hours. With the results obtained in this study, the optimal surface finish and pressing time to be used in the furniture industry is evidenced., In order to reduce the exploitation of wood from native forests, Brazil has been increasing forest plantations in recent years, with species such as pine and especially eucalyptus (Brazilian Tree [...]

Guidelines recommend measuring lipids when HIV-positive people enter care, before antiretroviral therapy, and regularly after therapy begins. Recent data indicate success with lifestyle changes that can improve lipids and lower cardiovascular risk, including simple dietary steps and an effective online smoking cessation program for people with HIV. When to start drug therapy for dyslipidemia depends on both lipid levels and coronary heart disease risk. Among people with HIV, the main lipid disorder is high triglycerides with low high-density lipoprotein cholesterol (HDL-C). Triglycerides above 500 mg/dL should generally be addressed before abnormal cholesterol levels. Statins aim to lower low-density lipoprotein cholesterol (LDL-C) and may have antiinflammatory benefits in people with HIV. Research confirms that statins lower cardiovascular event risk in the general population. Atorvastatin and rosuvastatin are preferred high-intensity statins. Pitavastatin has a good pharmacokinetic profile, even with HIV protease inhibitors, but it ranks as a low- or moderate-intensity statin. Fibrates, niacin, and omega-3 fatty acids have roles for some dyslipidemic people with HIV. Fibrates and omega-3 fatty acids are the preferred agents for isolated high triglycerides. Treatment of dyslipidemia may not attain atherogenic cholesterol goals in all patients, but there are incremental benefits in lowering non-HDL-C and LDL-C toward target levels., HIV care guidelines recommend close lipid monitoring in people with HIV. Department of Health and Human Services (DHHS) HIV treatment guidelines for adults and adolescents recommend regular fasting lipid measures: [...]

CASE #1 A 6-year-old girl was brought to the dermatology clinic by her parents for evaluation of a papular abdominal rash that featured scattered umbilicated pink papules. The rash, which [...]
