BACKGROUND: Transgender people are disproportionately affected by HIV. Despite their high vulnerability to HIV, lack of adequate epidemiological and surveillance data related to this population in many countries prevents provision of appropriate services. This paper summarizes descriptive findings from a national integrated biological and behavioral survey and discusses policy implications of the findings on HIV prevention among transgender women in Cambodia. METHODS: This cross-sectional study was conducted between December 2015 and February 2016...

BACKGROUND: Efforts to improve HIV diagnosis and antiretroviral therapy (ART) initiation among people living with HIV and reduce onward transmission of HIV rely on innovative interventions along multiple steps of the HIV care continuum. These innovative methods are particularly important for key populations, including men who have sex with men (MSM) and transgender women (TW). The HIV epidemic in Myanmar is concentrated among key populations, and national efforts now focus on reducing stigma and improving engagement of MSM and TW in HIV prevention and care...

The normal amine mechanism via proton transferring route (NAM-H) is widely accepted for synthesis of polypeptides with nonionic initiators. Besides proton, trimethylsilyl (TMS) group transferring process has been found in living/controlled polymerization initiated by N-TMS amine in experiments but the corresponding mechanism has never been proposed yet. In this work, we employed density functional theory (DFT) with solvation model to investigate the details of TMS-transfer mechanism, defined as NAM-TMS, for ring-opening polymerization of α-amino acid N-carboxyanhydride...

BACKGROUND: There are conflicting results in the literature on the impact of chorioamnionitis on neonatal respiratory morbidities. However, most studies are based on small clinical samples and fail to account for the competing risk of perinatal death. This study aimed to determine whether chorioamnionitis affects the incidence of respiratory distress syndrome (RDS) and bronchopulmonary dysplasia (BPD) after accounting for the increased risk of death. METHODS: Retrospective cohort study using linked birth and infant death registration and hospitalization records from Washington State between 2002 and 2011 (n = 763,671 singleton infants and n = 56,537 singleton preterm infants)...

Patients with Rheumatic diseases (RDs) are at an increased risk of malignancies compared with the general population. The aim of this study was to examine the relative frequency of several cancers in a single homogeneous cohort of patients with different RDs. Patients diagnosed with rheumatoid arthritis (RA), Ankylosing spondylitis (AS), Sjögren's syndrome (SS), systemic lupus erythematosus (SLE), systemic sclerosis (SSc), dermatomyositis (DM), or polymyositis were included. Out of 3982 adult residents admitted to the division of rheumatology, 61 malignancies were observed...

BACKGROUND: Many sub-Saharan African countries have adopted Option B+, a prevention of mother-to-child transmission approach providing HIV-infected pregnant and lactating women with immediate lifelong antiretroviral therapy. High maternal attrition has been observed in Option B+. Peer-based support may improve retention. METHODS: A 3-arm stratified cluster randomized controlled trial was conducted in Malawi to assess whether facility- and community-based peer support would improve Option B+ uptake and retention compared with standard of care (SOC)...

Concordance validity of commonly used performance validity tests (PVTs) was assessed in a sample of Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) veterans referred to an mTBI screening clinic in a south-eastern Veterans Affairs hospital. Veteran service members (total n = 184) completed the Rey-15, Repeatable Battery of the Assessment for Neuropsychological Status Effort Index (RBANS EI), and Reliable Digit Span (RDS) from the Wechsler Intelligence Scales. Kappa coefficients and percentage of agreement were established to determine the level of concordance between the three measures...

Persons who inject drugs (PWID) are at risk for adverse health outcomes as a result of their drug use, and the resulting social stigma makes this a difficult population to reach for interventions aimed at reducing morbidity and mortality. During our study of adult PWID aged ≤40 years living in San Diego during 2009 and 2010, we compared three different sampling methods: respondent-driven sampling (RDS), venue-based sampling at one syringe exchange program (SEP), and street-based outreach. We compared demographic, socioeconomic, health, and behavioral factors and tested participants for HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) and compared across the three methods...

Retinitis pigmentosa (RP) is the most common form of inherited retinal dystrophy. We recently identified mutations in REEP6, which encodes the receptor expression enhancing protein 6, in several families with autosomal recessive RP. REEP6 is related to the REEP and Yop1p family of ER shaping proteins and potential receptor accessory proteins, but the role of REEP6 in the retina is unknown. Here we characterise the disease mechanisms associated with loss of REEP6 function using a Reep6 knockout mouse generated by CRISPR/Cas9 gene editing...

The European Union defines rare diseases (RDs) as life-threatening or chronically debilitating conditions whose prevalence is less than 5 per 10,000. Moreover, for many RDs, including those of genetic origin, combined efforts are required to reduce morbidity or perinatal or early mortality, and address the considerable decline in an individual's quality of life and socioeconomic potential. Their specificities, i.e., a limited number of patients and scarcity of relevant knowledge and expertise, make RDs a unique condition which requires wide cooperation at a supranational level...

Engineered cell sheets that are fabricated by using temperature-responsive culture dishes are now available in the clinical setting. Engineered chondrocyte cell sheets are used in clinical trials for treating focal articular cartilage defects. However, the efficacy of engineered chondrocyte cell sheets for treating diffusely degenerated articular cartilage remains unknown. In the present study, we assessed the utility of engineered chondrocyte cell sheets for treating diffusely degenerated articular cartilage in a monoiodoacetate (MIA)-induced arthritis animal model...

Cell type-specific Cre driver lines have revolutionized the analysis of retinal cell types and circuits. We show that the transgenic mouse Rbp4-Cre selectively labels several retinal neuronal types relevant to the encoding of absolute light intensity (irradiance) and visual motion. In the ganglion cell layer (GCL), most marked cells are wide-field spiking polyaxonal amacrine cells (ACs) with sustained irradiance-encoding ON responses that persist during chemical synaptic blockade. Their arbors spread about 1 mm across the retina and are restricted to the inner half of the ON sublamina of the inner plexiform layer (IPL)...

INTRODUCTION: Brief potentially ictal rhythmic discharges (B(I)RDs) have been described in neonates and critically ill adults, and their association with seizures has been demonstrated. Their significance in noncritically ill adults remains unclear. We aimed to investigate their prevalence, electrographic characteristics, and clinical significance. METHODS: We identified adult patients with B(I)RDs who received long-term EEG recordings either in the epilepsy monitoring unit or in the ambulatory setting...

Multielectron processes in electrochemistry require the stabilization of reaction intermediates (RI) at the electrode surface after every elementary reaction step. Accordingly, the bond strengths of these intermediates are important for assessing the catalytic performance of an electrode material. Current understanding of microscopic processes in modern electrocatalysis research is largely driven by theory, mostly based on ab initio thermodynamics considerations, where stable reaction intermediates at the electrode surface are identified, while the actual free energy barriers (or activation barriers) are ignored...

BACKGROUND: Allogeneic hematopoietic cell transplantation (HCT) using human leukocyte antigen (HLA)-matched related donors (RDs) and allogeneic HCT using HLA-matched unrelated donors (URDs) produce similar outcomes for patients with acute myelogenous leukemia, whereas the donor source has been reported to be a predictor of outcomes in myelodysplastic syndrome. METHODS: Post-HCT outcomes for 1458 acute lymphoblastic leukemia patients from 2000 to 2011 were analyzed, and RD and URD transplants were compared...

OBJECTIVE: Immunoglobulin (Ig) G4-related aortic aneurysms (IgG4-AAs) are a special aortic aneurysm among IgG4-related diseases (IgG4-RDs), which are inflammatory and fibrous conditions characterized by tumorous swelling of affected organs and high serum IgG4 concentrations. Recently, IgG4-RD pathogenesis was shown to be associated with T-helper-2 (Th2) and regulatory T (Treg) dominant cytokine production, such as interleukin (IL)-4, IL-10, and IL-13. IL-6 is a key proinflammatory cytokine contributing to lymphocyte and plasmacyte maturation and to atherosclerosis and aneurysm development...

The present study aims to contribute to the ongoing discussion about the impact of discourse-linking deficits on the performance of individuals with aphasia by providing new data from a set of rarely investigated constructions: sentences in which a clitic pronoun coexists alongside with the full DP it agrees with. To do so, we use data of individuals with non-fluent aphasias who need to overcome the difficulties in direct object (accusative) clitic production. This results in overproduction of non-target clitic right dislocations (RDs) and clitic doubling (CD)...

A case-crossover study examined how PM2.5 from Asian Dust Storms (ADS) affects the number of emergency room (ER) admissions for cardiovascular diseases (CVDs) and respiratory diseases (RDs). Our data indicated that PM2.5 concentration from ADS was highly correlated with ER visits for CVDs and RDs. The odds ratios (OR) increased by 2.92 (95% CI: 1.22-5.08) and 1.86 (95% CI: 1.30-2.91) per 10 µg/m³ increase in PM2.5 levels, for CVDs and RDs, respectively. A 10 µg/m³ increase in PM2.5 from ADSs was significantly associated with an increase in ER visits for CVDs among those 65 years of age and older (an increase of 2...
