A Scoping Review of Oral Pre-exposure Prophylaxis for Cisgender and Transgender Adolescent Girls and Young Women: What Works and Where Do We Go from Here?

Adolescent girls and young women (AGYW) are disproportionately affected by HIV, and oral pre-exposure prophylaxis (PrEP) can reduce HIV acquisition. The purpose of this scoping review was to synthesize results from interventions along the PrEP continuum for AGYW to inform research and programs. We searched electronic databases for studies published between January 2012-July 2021 and conducted secondary reference searching.

The evolution of DREAMS: using data for continuous program improvement.

The DREAMS (Determined, Resilient, Empowered, AIDS-Free, Mentored, and Safe) Partnership, a public-private partnership launched by the United States President's Emergency Plan for AIDS Relief (PEPFAR), represents the largest investment in comprehensive HIV prevention for adolescent girls and young women (AGYW) ever made in a single global initiative. This paper describes the evolution of programming over time using the triangulation of multiple data sources to develop and refine an impactful program, as well as to improve efficacy and resource investment. Methods of analysis used to evolve this programming include reviews of literature on behavioral, biomedical and structural interventions, and HIV vulnerability; PEPFAR program data; external implementation science and impact studies;observations from site visits; in-depth reviews of program materials; and inputs from AGYW and other stakeholders.

AβPP-induced UPR Transcriptomic Signature of Glial Cells to Oxidative Stress as an Adaptive Mechanism to Preserve Cell Function and Survival.

Background: Alzheimer's disease (AD) and age-related macular degeneration (AMD) present similarities, particularly with respect to oxidative stress, including production of 4-Hydroxy-2- nonenal (HNE). AMD has been named the AD in the eye. The Müller cells (MC) function as a principal glia of the retina and maintain water/potassium, glutamate homeostasis and redox status.

Hydroquinone induces oxidative and mitochondrial damage to human retinal Müller cells (MIO-M1).

Purpose: Smoking is a risk factor in the development of a variety of neuroretinal diseases. Therefore, we have investigated the effects of hydroquinone (HQ), a toxicant that is present in high concentrations in cigarette smoke, on a human retinal Müller cell line (MIO-M1).

Methods: MIO-M1 cells were treated for 24h with four different concentrations of HQ (200μM, 100μM, 50μM, and 25μM).

Pin site care: guidance and key recommendations.

Pin site infection is the most common complication of external fixation, a complex orthopaedic procedure used to stabilise fractures and correct limb deformity. The care of pin sites has long been debated among healthcare professionals. It is widely acknowledged that there is a lack of high quality research in this area.

Current approaches and future prospects for stem cell rescue and regeneration of the retina and optic nerve.

The 3 most common causes of visual impairment and legal blindness in developed countries (age-related macular degeneration, glaucoma, and diabetic retinopathy) share 1 end point: the loss of neural cells of the eye. Although recent treatment advances can slow down the progression of these conditions, many individuals still suffer irreversible loss of vision. Research is aimed at developing new treatment strategies to rescue damaged photoreceptors and retinal ganglion cells (RGC) and to replace lost cells by transplant.

Impact of defects on the surface chemistry of ZnO(0001 macro)-O.

Scanning tunneling microscopy and core level photoelectron spectroscopy measurements have been used to investigate the morphology of ZnO(0001 macro)-O, and its reactivity with carbon monoxide and carbon dioxide, as a function of surface preparation. Real space images of the surface indicate that increasing the substrate anneal temperature during preparation significantly reduces the surface step density. Surface defect concentration is also monitored by employing formic acid as a chemical probe, which is shown to adsorb dissociatively (HCOOH --> [HCOO](-) + H(+)) only on zinc cations at step edges.

Expression of tumour necrosis factor-alpha, interleukin-6, and interleukin-2 mRNA in the jejunum of patients with coeliac disease.

Background: A T-cell-mediated immune response may be responsible for the enteropathy seen in coeliac disease (CD), but it is unclear whether this is initiated in the epithelium or the lamina propria. We studied the site and number of cells expressing mRNA encoding the cytokines interleukin-2 (IL-2), IL-6, and tumour necrosis factor-alpha in jejunal biopsy specimens from patients with untreated or treated CD and normal controls.

Methods: Tissue sections were hybridized with 35S-labelled DNA oligonucleotide probes specific for each cytokine RNA sequence.

Adoptive immunotherapy administered via the hepatic artery and intralesional interleukin-2 in hepatocellular carcinoma.

We assessed the feasibility of using lymphokine-activated killer cells (adoptive immunotherapy) with infusions of interleukin-2 when given regionally in three patients with unresectable primary hepatocellular carcinoma (PHC). In 2 patients, 2 cycles, which included a bolus of LAK (10(7) to 10(8) cells followed by a 4-hourly infusion of IL-2 were administered via selective arterial catheterization of the hepatic artery. One further patient received 3 cycles of IL-2 alone by direct intralesional and perilesional injections.
