Micro-costing for national-scale azithromycin mass drug administration to improve child survival in Niger
As programs for azithromycin mass drug administration (AZ-MDA) to reduce child mortality have begun in some parts of West Africa, it is imperative to understand their financial costs. We combined a micro-costing framework and observations from an implementation-focused sub-study within the AVENIR trials in 80 communities in the Dosso region of Niger to estimate the national health sector financial costs of a scaled-up programmatic approach for az…
Economic costs of TB and HIV in high-TB-burden countries
INTRODUCTION: Tuberculosis (TB) remains a significant health burden in 25 low- and middle-income countries. Despite TB being more cost-effective to prevent and treat its funding is disproportionately lower than that of HIV. This study aims to assess the economic costs of TB versus HIV and evaluate the returns on investment in TB prevention compared to HIV. METHODS: The study uses a microfoundations behavioural model to estimate the economic costs…
Integration of a vertical voluntary medical male circumcision program into routine health services in Zimbabwe
The global health community has recognized the importance of integrating and sustaining health programs within national health systems rather than managing stand-alone ‘vertical’ interventions. Corresponding with these objectives, international aid donors are embracing the principle of localization. Voluntary Medical Male Circumcision (VMMC) in Zimbabwe is a large vertical HIV prevention program that was primarily funded through development assis…
Evolution of differences in clinical presentation across epidemic waves among patients with Covid-like-symptoms who received care at the Mexican Social Security Institute
Background: Timely monitoring of SARS-CoV-2 variants is crucial to effectively managing both prevention and treatment efforts. In this paper, we aim to describe demographic and clinical patterns of individuals with COVID-19-like symptoms during the first three epidemic waves in Mexico to identify changes in those patterns that may reflect differences determined by virus variants. Methods: We conducted a descriptive analysis of a large database co…
The relationship between the gendered norm of eating last and mental health of newly married women in Nepal
Eating last is a gendered cultural norm in which the youngest daughters-in-law are expected to eat last after serving others in the household, including men and in-laws. Using women's eating last as an indicator of women's status, we studied the association between eating last and women's mental health. Using four rounds of prospective cohort data of 18-25-year-old newly married women (n = 200) cohabiting with mothers-in-law between 2018 and 2020…
Group psychedelic therapy
Adopting group therapy protocols where feasible would significantly reduce the cost of psychedelic-assisted therapies. By enhancing the number of patients served per clinician, group therapy could also ameliorate the anticipated shortage of appropriately trained clinicians, thereby accelerating access to these promising new therapies
The Role of Gender Norms on Intimate Partner Violence Among Newly Married Adolescent Girls and Young Women in India
Gender norms have been posited to impact intimate partner violence (IPV), but there is scant evidence of the longitudinal association between community-level gender norms and IPV. Using longitudinal data on 3,965 married girls surveyed in India, we fitted mixed-effects ordinal and binary logistic regression models for physical IPV intensity and occurrence of sexual IPV. We found a 26% increase in the odds that women experience frequent physical I…
One vaccine to counter many diseases? Modeling the economics of oral polio vaccine against child mortality and Covid-19
Introduction: Recent reviews summarize evidence that some vaccines have heterologous or non-specific effects (NSE), potentially offering protection against multiple pathogens. Numerous economic evaluations examine vaccines' pathogen-specific effects, but less than a handful focus on NSE. This paper addresses that gap by reporting economic evaluations of the NSE of oral polio vaccine (OPV) against under-five mortality and COVID-19. Materials and m…
Covid-19 outbreak in a state prison
Our adapted framework facilitates systematically assessing prison-based infectious disease outbreaks and multi-level interventions. We find implementing some recommended public health strategies may have contributed to outbreak containment. However, even with a rapidly mobilized, inter-institutional response, failure to decarcerate created an overreliance on chance conditions. This left the facility vulnerable to future catastrophic outbreaks and…
Scaling up public mental health care in Sub-Saharan Africa
The COVID-19 pandemic is setting off a colossal escalation of global mental health care needs, well-publicized across scientific, media, policymaker, and civil society domains. The pandemic highlights disparities in healthcare access and reinvigorates the push for universal coverage. Learning from HIV strategies, we must seize this historical moment to improve the public mental health care cascade in SSA and capitalize on the powerful alliances r…
Design and impact evaluation of a digital reproductive health program in Rwanda using a cluster randomized design

Prison environment and non-communicable chronic disease modifiable risk factors
BACKGROUND: There is a lack of evidence regarding chronic disease modifiable risk factors among prisoner populations in Latin America. The purpose of this study was to estimate the prevalence of modifiable risk factors for chronic diseases and to assess their relationship with length of incarceration. METHODS: We analysed data from a cross sectional study in which 4241 prisoners were randomly selected to answer a questionnaire with socio-demograp…
The Impact of HIV/ Aids[1]
Community-based prevention leads to an increase in condom use and a reduction in sexually transmitted infections (STIs) among men who have sex with men (MSM) and female sex workers (FSW)
Important changes in behaviours related to an increase in prevention activities translated to reductions in STI sero-prevalence in AP, India. In contrast with non-FPP sites, the FPP sites experienced an intense community approach as part of the FPP intervention, and the general increase in condom use and its effect on STI sero-prevalence reflected the efficacy of these intense prevention activities focused on key populations in AP
Leroy Et Al. Respond
We read Woolf and Johnson’s letter with great interest. The similarity of the findings for developing countries and the United States is impressive,1 as they reflect the influence of the shared assumptions in the research community that lead to low investments in research to improve the fidelity (quality) of health care delivery and utilization. We have a slight correction to make to their letter. Our research shows that 6 million (not 4 million)…
Current Priorities in Health Research Funding and Lack of Impact on the Number of Child Deaths per Year
We determined the proportion of research on childhood mortality directed toward better medical technology (i.e., by improving old technology or creating new technology) compared with research on technology delivery and utilization. We also estimated mortality reductions from a research-funding strategy focusing primarily on developing technology compared with one that also focused on delivery and utilization. Ninety-seven percent of grants were f…
Demography and sex work characteristics of female sex workers in India
BACKGROUND: The majority of sex work in India is clandestine due to unfavorable legal environment and discrimination against female sex workers (FSWs). We report data on who these women are and when they get involved with sex work that could assist in increasing the reach of HIV prevention activities for them. METHODS: Detailed documentation of demography and various aspects of sex work was done through confidential interviews of 6648 FSWs in 13 …
Correlates of condom use in a sample of MSM in Ecuador
Our data illustrate the urgent need for targeted HIV-prevention programs for MSM populations in Ecuador. MSM have the highest HIV prevalence in the country, and condom use is extremely low. It is imperative that prevention strategies be re-evaluated and re-prioritized to more effectively respond to the Ecuadorian epidemic
Risk behaviors of 15–21 year olds in Mexico lead to a high prevalence of sexually transmitted infections
The results presented in this study show a startlingly high prevalence of HSV-2 among sexually active Mexican adolescents in poor urban areas, suggesting that this group has participated to a great extent in risky sexual practices. The relationships between socioeconomic environment and adolescent risk behavior need to be better understood if we are to design preventive interventions that modify the determinants of risk behaviors
How much attention is needed towards men who sell sex to men for HIV prevention in India
These data indicate that men who sell sex to men are at much higher risk of acquiring and transmitting HIV than women who sell sex. Therefore, men who sell sex to men and their clients warrant substantial attention for comprehensive HIV prevention in India
Estimated Numbers of Men and Women Infected with HIV/Aids in Tijuana, Mexico
High risk of HIV in non-brothel based female sex workers in India
About half the FSWs do not use condom consistently with their clients in this Indian state putting them at high risk of HIV infection. Non-brothel-based FSWs, who form the majority of sex workers in India, were at a significantly higher risk of HIV infection as compared with brothel-based FSWs. With their high vulnerability, the success of expansion of HIV prevention efforts will depend on achieving and sustaining an environment that enables HIV …
Risky Business
While condoms are an effective defense against the transmission of HIV, large numbers of sex workers are not using them. We argue that some sex workers are willing to take the risk because clients are willing to pay more to avoid using condoms. Using data from Mexico, we estimate that sex workers received a 23 percent premium for unprotected sex. The premium represents a value of one life year of between $14,760 and $51,832 or one to five times a…
