Background: Therapy with HIV protease inhibitors (PI) has been shown to worsen glucose and lipid metabolism, but whether these changes are caused by direct drug effects, changes in disease status, or body composition is unclear. Therefore, we tested the effects of the PI combination lopinavir and ritonavir on glucose and lipid metabolism in HIV-negative subjects.
Methods: A dose of 400 mg lopinavir/100 mg ritonavir was given twice a day to 10 HIV-negative men. Fasting glucose and insulin, lipid and lipoprotein profiles, oral glucose tolerance, insulin sensitivity by euglycemic hyperinsulinemic clamp, and body composition were determined before and after lopinavir/ritonavir treatment for 4 weeks.
Results: On lopinavir/ritonavir, there was an increase in fasting triglyceride (0.89 +/- 0.15 versus 1.63 +/- 0.36 mmol/l; P = 0.007), free fatty acid (FFA; 0.33 +/- 0.04 versus 0.43 +/- 0.06 mmol/l; P = 0.001), and VLDL cholesterol (15.1 +/- 2.6 versus 20 +/- 3.3 mg/dl; P = 0.05) levels. There were no changes in fasting LDL, HDL, IDL, lipoprotein (a), or total cholesterol levels. Fasting glucose, insulin, and insulin-mediated glucose disposal were unchanged, but on a 2 h oral glucose tolerance test glucose and insulin increased. There were no changes in weight, body fat, or abdominal adipose tissue by computed tomography.
Conclusion: Treatment with 4 weeks of lopinavir/ritonavir in HIV-negative men causes an increase in triglyceride levels, VLDL cholesterol, and FFA levels. Lopinavir/ritonavir leads to a deterioration in glucose tolerance at 2 h, but there is no significant change in insulin-mediated glucose disposal rate by euglycemic hyperinsulinemic clamp.

Compulsory Isolation and Rehabilitation Center in Sichuan Province, Chengdu No. 2, Chengdu, China.
Objective: To study the heterogeneity and influencing factors of self-acceptance of drug addicts in compulsory isolation in 2 drug rehabilitation centers in Sichuan Province, and to analyze the effects of different types of self-acceptance on subthreshold depression in drug addicts, in order to provide useful references for improving their mental health.
Methods: Self-acceptance Questionnaire (SAQ), Drug use Stereotype Threat Scale(DSTS) and Center for Epidemiologic Studies Depression Scale(CES-D) were used to conduct a questionnaire survey in January 2024 on 1068 drug addicts in two compulsory isolation drug rehabilitation centers in Sichuan Province.
Results: Drug addicts self-acceptance can be categorized into 5 potential categories; men were more likely than women to show lower self-acceptance in the 'low-low'(β = 0.

Purpose: Contemporary antiretroviral (ARV) medications are used by millions of men for HIV treatment worldwide. Limited data exist on their direct effect on sperm motility. This pilot study hypothesizes that in vitro exposure to ARVs will reduce sperm kinematic and motility parameter values.

Background: Tuberculosis (TB) is the leading cause of death among people with HIV and a major global health challenge. Subclinical cardiovascular manifestations of TB are poorly documented in high TB and HIV burden countries.
Objectives: The purpose of this study was to quantify the prevalence of cardiovascular involvement in TB patients and investigate changes after completion of anti-TB treatment.

Division of Cancer Epidemiology, McGill University, Montréal, Quebec, Canada. Electronic address:
Background: Gay, bisexual, and other men who have sex with men (gbMSM) have a higher risk of human papillomavirus (HPV) infection and related diseases and would benefit from preventive measures such as HPV vaccination. We assessed the association between HPV vaccination and anal HPV infection in HIV-negative gbMSM and gbMSM living with HIV from the Lubricant Investigation in Men to Inhibit Transmission of HPV Infection study.
Methods: Participants attended 7 visits over 12 months where they provided a nurse-collected anal sample and self-completed a questionnaire on risk factors and HPV vaccination.
