RESUMEN
The women, men, and transgender people who sell sex globally have disproportionate risks and burdens of HIV in countries of low, middle, and high income, and in concentrated and generalised epidemic contexts. The greatest HIV burdens continue to be in African female sex workers. Worldwide, sex workers still face reduced access to needed HIV prevention, treatment, and care services. Legal environments, policies, police practices, absence of funding for research and HIV programmes, human rights violations, and stigma and discrimination continue to challenge sex workers' abilities to protect themselves, their families, and their sexual partners from HIV. These realities must change to realise the benefits of advances in HIV prevention and treatment and to achieve global control of the HIV pandemic. Effective combination prevention and treatment approaches are feasible, can be tailored for cultural competence, can be cost-saving, and can help to address the unmet needs of sex workers and their communities in ways that uphold their human rights. To address HIV in sex workers will need sustained community engagement and empowerment, continued research, political will, structural and policy reform, and innovative programmes. But such actions can and must be achieved for sex worker communities everywhere.

The goals of the international response to control the HIV epidemic include high antiretroviral therapy (ART) coverage with HIV viral suppression, as well as reduction of new infections. ART use at individual and population levels reduces HIV morbidity and mortality and likely reduces HIV incidence. HIV viral suppression requires high levels of ART adherence, which necessitates support through behavioural and structural interventions to optimise effectiveness of the use of ART for prevention. Many people living with HIV remain unaware that they are HIV-infected, and HIV transmission risk is high during early infection, therefore ART expansion should be accompanied by other interventions in order to achieve the promise of treatment for prevention. Biomedical and behavioural prevention efforts focused on HIV-uninfected individuals at substantial risk of HIV acquisition are also needed to control the epidemic. Maintaining prevention programming is essential during the scale up of ART to reduce HIV transmission.

Cardiopulmonary bypass is widely believed to be injurious to renal function. The unknown consequences of renal dysfunction with modern techniques of bypass in the elderly caused us to examine creatinine clearance and the excretion of sensitive marker proteins in older adult patients undergoing CABG. Thirty male patients were divided into three groups: group I with an age up to 60 years, group II with an age between 61 and 70 years, inclusive and group III 71 years and over. Serum creatinine and urea, creatinine clearance, and alpha1-microglobulin (alpha1-MG), N-acetyl-beta-D-glucosaminidase (NAG), Tamm-Horsfall protein (TH) and immunoglobulin G (IgG) were all measured daily, pre- and postoperatively. Creatinine clearance remained lower in the older patients without significant differences. Raised excretion rates of alpha1-MG, and IgG were seen after CPB. The increase in alpha1-MG and NAG during the postoperative period revealed tubular damage in all elderly patients. Measurements of alpha1-MG, NAG and IgG represent useful supplements to standard clinical tests for recognizing early and differentiated changes in renal function.

INTRODUCTION: For the long-term monitoring of kidney function, polytraumatized patients were examined and routine as well as specialized parameters were compared. MATERIALS AND METHODS: 30 patients of the Surgical Intensive Care Unit (ICU) were examined daily over the entire period they stayed in the ICU. The patients were retrospectively classified as either survivors or deceased patients. Group 1 consisted of 20 patients who resided in the ICU for 11-15 (Median 14) days before they could be transferred to a normal hospital unit. Group 2 consisted of 10 patients who had passed away after 13-18 (Median 16) days in the ICU. In addition to the routine parameters diuresis, serum creatinine and serum urea, specialized parameters for kidney function including the excretion rates of alpha1-microglobulin (alpha1-MG), N-Acetyl-beta-D-glucosaminidase (NAG), angiotensinase A (ATA) and immunoglobulin G (IgG) were determined. RESULTS: Similar biometric data were shown by all patients at admission into the ICU, but differences did exist regarding the Revised Trauma Score, Injury Severity Score and the APACHE-II-Score. In the period between the 5th and 8th day of intensive treatment almost all patients showed pathological excretion rates of tubular and glomerular parameters whereby no increased frequency of unusual events could be determined at these time-points. CONCLUSION: During treatment in the ICU, all examined patients showed at times pathological excretion rates of specialized kidney function parameters. Such transient damage was only apparent in a few of the patients when the standard parameters serum creatinine and serum urea were employed. In 90% of the surviving patients the kidney parameters had normalized until the time they were transferred, indicating that such parameters reflected the general state of health of these patients.
