BACKGROUND Population-based HIV incidence, prevalence, and mortality rates among men who have sex with men (MSM) have been unavailable, limiting assessment of racial/ethnic disparities and epidemic dynamics. METHODS Using estimated numbers of MSM aged >or=18 years by race/ethnicity as denominators, from models in our prior work, we estimated MSM HIV prevalence and mortality rates for 2006-200...

BACKGROUND Estimated numbers of men who have sex with men (MSM) by race/ethnicity and mortality rates among such MSM with HIV/AIDS are unavailable. This hampers efficient targeting of HIV/AIDS prevention and care resources. METHODS An existing estimation methodology was adapted to develop MSM population estimates by race/ethnicity for Miami-Dade County, Florida. We ascertained and characteriz...

In the United States, men who have sex with men (MSM) constitute the risk group in which the prevalence of new HIV infection is increasing. The percentage of undiagnosed HIV infection and HIV risk behaviors in MSM and non-MSM participating in an emergency department-based rapid HIV screening program were compared. Medical records of all male patients participating in the program from May 2008 t...

OBJECTIVES To examine the epidemiology of HIV among black and minority ethnic (BME) men who have sex with men (MSM) in England and Wales (E&W). METHODS Ethnicity data from two national HIV/AIDS surveillance systems were reviewed (1997-2002 inclusive), providing information on new HIV diagnoses and those accessing NHS HIV treatment and care services. In addition, undiagnosed HIV prevalence amo...

Amorphous-selenium (a-Se) based photodetectors are promising candidates for imaging devices, due to their high spatial resolution and response speed, as well as extremely high sensitivity enhanced by an internal carrier multiplication. In addition, a-Se is reported to show sensitivity against wide variety of wavelengths, including visible, UV and X-ray, where a-Se based flat-panel X-ray detecto...

BACKGROUND Recruiting valid samples of men who have sex with men (MSM) is a key component of the US human immunodeficiency virus (HIV) surveillance and of research studies seeking to improve HIV prevention for MSM. Social media, such as Facebook, may present an opportunity to reach broad samples of MSM, but the extent to which those samples are comparable with men recruited from venue-based, ti...

To increase the responsivity is one of the vital issues for a photodetector. By employing ZnO as a representative material of ultraviolet photodetectors and Si as a representative material of visible photodetectors, an impact ionization process, in which additional carriers can be generated in an insulating layer at a relatively large electric field, has been employed to increase the responsivi...

BACKGROUND Although increased prevalence of transfusion transmissible infections (TTI) among "men who have sex with men" (MSM) has been well documented, the exclusion of MSM as blood donors is contested. The aim of this systematic review is to find studies that describe the risk of TTI in MSM blood donors. METHODS We searched MEDLINE, Embase, The Cochrane Central Register of Controlled Trials...

A new tracking design for laser systems with different arrangements of a quadrant photodetector, based on the principle of active disturbance rejection control is suggested. The detailed models of quadrant photodetector with standard add–subtract, difference-over-sum and diagonal-differenceover-sum algorithms for displacement signals are included in the control loop. Target moving, nonlinearity...
