BACKGROUND We assessed risk factors for viremia and drug resistance among long-term recipients of antiretroviral therapy (ART) in South Africa. METHODS In 2008, we conducted a cross-sectional study among patients receiving ART for 12 months or more. Genotypic resistance testing was performed on individuals with a viral load higher than 400 RNA copies/ml.(More)
Since the early 1950s, Papanicolaou ("Pap") cytology screening has dramatically reduced cervical cancer mortality in most high-income settings. Currently, human papillomavirus (hpv) vaccination has the greatest potential to reduce the global burden of cervical cancer and precancerous lesions. However, as the prevalence of precancerous lesions declines,(More)
BACKGROUND: Emergence of HIV-1 drug resistance is at times an inevitable and anticipated consequence of antiretroviral therapy (ART) failure. We examined drug resistance patterns and virus re-suppression among subtype C-infected South African patients receiving first-line ART. METHODS: Treatment records of 431 patients on NNRTI-containing regimens for a(More)
The design of a fully-integrated linearized CMOS bidirectional distributed amplifier (DA) based active circulator with broadband distortion cancellation capability is presented. The S<sub>21</sub> differential power gain peaks at 7 dB and then rolls off to a unity gain bandwidth of 11.5 GHz. The simulated tunable isolation performance is better than -26 dB.(More)
BACKGROUND India launched a national conditional cash transfer program, Janani Suraksha Yojana (JSY), aimed at reducing maternal mortality by promoting institutional delivery in 2005. It provides a cash incentive to women who give birth in public health facilities. This paper studies the extent of program uptake, reasons for participation/non participation,(More)
Around 3% of the world's population (n = 214 million people) has crossed international borders for various reasons. Since March 2011, Syria has been going through state of political crisis and instability resulting in an exodus of Syrians to neighbouring countries. More than 1 million Syrian refugees are residents of Lebanon, Jordan, Turkey, Egypt and North(More)
BACKGROUND Affordable strategies to prevent treatment failure on first-line regimens among HIV patients are essential for the long-term success of antiretroviral therapy (ART) in sub-Saharan Africa. WHO recommends using routinely collected data such as adherence to drug-refill visits as early warning indicators. We examined the association between adherence(More)
A fully differential CMOS distributed amplifier (DA) with a 10-dB pass band gain and 12-GHz bandwidth is described. The fully differential eight-stage DA employs a feedforward distortion cancellation topology. The circuit attains wide bandwidth operation with a high gain and minimal linearity degradation. Input and output are matched to 50-/spl Omega/ using(More)
Child burn mortality differs widely between regions and is closely related to material deprivation, but reports on their global distribution are few. Investigating their country level distribution in light of economic level and income inequality will help assess the potential for macro-level improvements. We extracted data for child burn mortality from the(More)
