Progress toward the UNAIDS 90-90-90 targets among female sex workers and sexually exploited female adolescents in Juba and Nimule, South Sudan.

Background: Little is known about HIV in South Sudan and even less about HIV among female sex workers (FSW). We characterized progress towards UNAIDS 90-90-90 targets among female sex workers (FSW) and sexually exploited female adolescents in Juba and Nimule, South Sudan.

Methods: We conducted a biobehavioral survey of FSW and sexually exploited female adolescents using respondent-driven sampling (RDS) in Juba (November 2015-March 2016) and in Nimule (January-March 2017) to estimate achievements toward the UNAIDS 90-90-90 targets (90% of HIV-positive individuals know their status; of these, 90% are receiving antiretroviral therapy [ART]; and of these, 90% are virally suppressed).

High HIV and syphilis prevalence among female sex workers in Juba, South Sudan.

HIV prevalence is estimated to be 2.7% in South Sudan; however, little is known about the young country's epidemic. We conducted a respondent-driven sampling biobehavioral survey in Juba of female sex workers (FSW) aged ≥15 years who sold or exchanged sex in the last 6 months to learn more about this population.

Placental changes caused by food restriction during early pregnancy in mice are reversible.

In a previous study, 50% calorie restriction in mice from d1.5 to 11.5 of pregnancy resulted in reduced placental weights and areas,relative sparing of labyrinth zone area compared to junctional zone area, and dramatic changes in global gene expression profiles.

Leptin and the placental response to maternal food restriction during early pregnancy in mice.

Several studies have demonstrated that maternal undernutrition or overnutrition during pregnancy can have negative consequences for the health of children born to these pregnancies, but the physiological mechanisms by which this occurs are not completely understood. During periods of food restriction, concentrations of leptin decline, whereas leptin is elevated in obesity, suggesting that it may play a role in the response to altered nutrition during pregnancy. This study compares placental development and global placental gene expression profiles at Day 11.

Embryonic and fetal cells which are not diseased or defective; possible sources of genes for disease prevention or treatment.

Cancer and other diseases may be a natural biological event, the activities of which may be dependent on the constitution of the individual. Where fetal and embryonic cells are not diseased or faulty or defective, they may be useful as therapies against cancer and other diseases.
