1.  Trends in all-cause mortality during the scale-up of an antiretroviral therapy programme: a cross-sectional study in Lusaka, Zambia 
Abstract
Objective
To follow the trends in all-cause mortality in Lusaka, Zambia, during the scale-up of a national programme of antiretroviral therapy (ART).
Methods
Between November 2004 and September 2011, we conducted 12 survey rounds as part of a cross-sectional study in Lusaka, with independent sampling in each round. In each survey, we asked the heads of 3600 households to state the number of deaths in their households in the previous 12 months and the number of orphans aged less than 16 years in their households and investigated the heads’ knowledge, attitudes and practices related to human immunodeficiency virus (HIV).
Findings
The number of deaths we recorded – per 100 person–years – in each survey ranged from 0.92 (95% confidence interval, CI: 0.78–1.09) in September 2011, to 1.94 (95% CI: 1.60–2.35) in March 2007. We found that mortality decreased only modestly each year (mortality rate ratio: 0.98; 95% CI: 0.95–1.00; P = 0.093). The proportion of households with orphans under the age of 16 years decreased from 17% in 2004 to 7% in 2011. The proportions of respondents who had ever been tested for HIV, had a comprehensive knowledge of HIV, knew where to obtain free ART and reported that a non-pregnant household member was receiving ART gradually increased.
Conclusion
The expansion of ART services in Lusaka was not associated with a reduction in all-cause mortality. Coverage, patient adherence and retention may all have to be increased if ART is to have a robust and lasting impact at population level in Lusaka.

2.  Epidemiologic Features of Vulvovaginal Candidiasis among Reproductive-Age Women in India 
Background. Vulvovaginal candidiasis is characterized by curd-like vaginal discharge and itching, and is associated with considerable health and economic costs. Materials and Methods. We examined the incidence, prevalence, and risk factors for vulvovaginal candidiasis among a cohort of 898 women in south India. Participants completed three study visits over six months, comprised of a structured interview and a pelvic examination. Results. The positive predictive values for diagnosis of vulvovaginal candidiasis using individual signs or symptoms were low (<19%). We did not find strong evidence for associations between sociodemographic characteristics and the prevalence of vulvovaginal candidiasis. Women clinically diagnosed with bacterial vaginosis had a higher prevalence of vulvovaginal candidiasis (Prevalence 12%, 95% CI 8.2, 15.8) compared to women assessed to be negative for bacterial vaginosis (Prevalence 6.5%, 95% 5.3, 7.6); however, differences in the prevalence of vulvovaginal candidiasis were not observed by the presence or absence of laboratory-confirmed bacterial vaginosis. Conclusions. For correct diagnosis of vulvovaginal candidiasis, laboratory confirmation of infection with Candida is necessary as well as assessment of whether the discharge has been caused by bacterial vaginosis. Studies are needed of women infected with Candida yeast species to determine the risk factors for yeast's overgrowth.

3.  Bacterial Vaginosis and Risk for Trichomonas Vaginalis Infection: A Longitudinal Analysis 
Sexually transmitted diseases  2011;38(9):882-886.
Background
Bacterial vaginosis (BV) and Trichomonas vaginalis (TV), have been estimated to affect one-quarter to one-third of sexually active women worldwide, and are often found concurrently. Few studies have examined this relationship longitudinally to better understand the direction and temporality of this association.
Methods
Between 2005 and 2006, a cohort of 853 young, sexually active women was followed in Mysore, India; participants were interviewed and tested for BV and TV at baseline, and at three- and six-month visits. Generalized estimating equations were used to estimate how changes in vaginal flora between consecutive visits – as defined by Nugent diagnostic criteria for BV - were related to the risk of TV infection at the latter visit, adjusted for sociodemographic and behavioral covariates. Treatment was offered to women with TV and/or symptomatic BV.
Results
After adjustment for covariates, participants with abnormal flora at two consecutive visits had nine times higher risk of TV (95% CI 4.1, 20.0) at the latter visit, relative to those with persistently normal flora. An increased risk of TV was also observed for participants whose flora status changed from normal to abnormal (aRR 7.11, 95% CI 2.8, 18.2) and from abnormal to normal (aRR 4.50, 95% CI 1.7, 11.8).
Conclusions
Women experiencing abnormal flora during a three-month span appear to have significantly increased risk of acquiring TV infection. Reproductive-age women in low-resource settings found to have abnormal vaginal flora should be assessed for TV.

4.  ACASI and Face-to-Face Interviews Yield Inconsistent Estimates of Domestic Violence Among Women in India: The Samata Health Study 2005-2009 
Journal of interpersonal violence  2011;26(12):2437-2456.
Background
Audio computer-assisted self-interviews (ACASI) are increasingly used in health research to improve the accuracy of data on sensitive behaviors. However, evidence is limited on its use among low-income populations in countries like India and for measurement of sensitive issues such as domestic violence.
Method
We compared reports of domestic violence and three less sensitive behaviors related to household decision making and spousal communication in ACASI and face-to-face interviews (FTFI) among 464 young married women enrolled in a longitudinal study of gender-based power and adverse health outcomes in low-income communities in Bangalore, India. We used a test-retest design. At the 12-month study visit, we elicited responses from each participant through FTFI first, followed by ACASI. At the 24-month visit, we reversed the order, implementing ACASI first, followed by FTFI. Univariable log-linear regression models and kappa statistics were used to examine ACASI’s effects on self-reports.
Results
Regression results showed significantly lower reporting in ACASI relative to FTFI at both visits, including for domestic violence (12-month risk ratio [RR] = 0.61, 95% CI = 0.52, 0.73; 24-month RR = 0.74, 95% CI = 0.62, 0.89). Response agreement between interview modes, calculated by kappa scores, was universally low, though highest for domestic violence (12-month κ = 0.45; 24-month κ = 0.48). Older age and greater educational attainment appeared associated with higher response agreement.
Conclusions
Greater reporting in FTFI may be due to social desirability bias for the less sensitive questions and perceptions of therapeutic benefit for domestic violence. These results cast doubt on the appropriateness of using ACASI for measurement of sensitive behaviors in India.

5.  Highly-cited estimates of the cumulative incidence and recurrence of vulvovaginal candidiasis are inadequately documented 
BMC Women's Health  2014;14:43.
Background
Available literature concerning the epidemiologic or clinical features of vulvovaginal candidiasis commonly reports that: 75% of women will experience an episode of vulvovaginal candidiasis in their lifetimes, 50% of whom will experience at least a second episode, and 5-10% of all women will experience recurrent vulvovaginal candidiasis (≥4 episodes/1 year). In this debate we traced the three commonly cited statistics to their presumed origins.
Discussion
It is apparent that these figures were inadequately documented and lacked supporting epidemiologic evidence. Population-based studies are needed to make reliable estimates of the lifetime risk of vulvovaginal candidiasis and the proportion of women who experience recurrent candidiasis.
Summary
The extent to which vulvovaginal candidiasis is a source of population-level morbidity remains uncertain.
