  • Estimating the risk of post-Covid condition in deprived communities, migrants and ethnic minorities in England

    Open AccessWing Lam Erica Fong, Sarah Beale et al.ARTICLEJournal of Epidemiology and…2026Citada por: 1Referências: 33

    BACKGROUND: Deprived communities, migrants and ethnic minorities were disproportionately affected by COVID-19 and may, therefore, be at a higher risk of post-COVID condition (PCC). This analysis, using data from the Virus Watch study, investigates how deprivation, migration status and ethnic minority status influence PCC risk in both the full cohort (all regardless of infection status) and those with a confirmed COVID-19 infection. METHODS: A sub…

    Open AccessLara Goscé, Kasim Allel et al.ARTICLEPLOS Global Public Health2024

    The Purified Protein Derivative tuberculin skin tests (TST) and blood-based Mycobacterium tuberculosis (M . tb) specific interferon-gamma release assays (IGRA) are the currently used tests for identifying individuals with TB infection for preventive treatment. However, challenges around access and implementation have limited their use. Novel M . tb specific skin tests (TBST) such as Diaskintest, ESAT6-CFP10 (C-TST), C-Tb (also known as Cy-Tb), an…

  • Tobacco smoking clusters in households affected by tuberculosis in an individual participant data meta-analysis of national tuberculosis prevalence surveys

    Open AccessYohhei Hamada, Matteo Quartagno et al.ARTICLEPLOS Global Public Health2024

    Tuberculosis (TB) and non-communicable diseases (NCD) share predisposing risk factors. TB-associated NCD might cluster within households affected with TB requiring shared prevention and care strategies. We conducted an individual participant data meta-analysis of national TB prevalence surveys to determine whether NCD cluster in members of households with TB. We identified eligible surveys that reported at least one NCD or NCD risk factor through…

  • Tuberculin skin test surveys and the Annual Risk of Tuberculous Infection in school children in Northern KwaZulu-Natal

    Open AccessTom Yates, Siphiwe Cebekhulu et al.ARTICLEPLOS Global Public Health2024

    Tuberculin skin test surveys in primary school children can be used to quantify Mycobacterium tuberculosis transmission at community level. KwaZulu-Natal province, South Africa, is home to 11.5 million people and suffers a burden of tuberculosis disease that is among the highest in the world. The last tuberculin survey in the province was undertaken in 1979. We performed a tuberculin skin test survey nested within a demographic and health househo…

  • Discrimination, disadvantage and disempowerment during Covid-19

    Open AccessMayuri Gogoi, Irtiza Qureshi et al.ARTICLEInternational Journal for Equity…2024

    Our research demonstrates how an intrasectional lens can help better understand how different forms of mutually reinforcing inequities exist at all levels within the healthcare workforce and how these impact HCWs from certain backgrounds who face greater disadvantage, discrimination and disempowerment, particularly during times of crisis like the COVID-19 pandemic

  • Mpox (monkeypox) risk and mortality associated with HIV infection

    Open AccessAdesola Yinka-Ogunleye, Mahmood Dalhat et al.ARTICLEBMJ Global Health2023

    INTRODUCTION: Recent outbreaks of mpox are characterised by changes in the natural history of the disease, the demographic and clinical characteristics of the cases, and widening geographical distribution. We investigated the role of HIV and other sexually transmitted infections (STIs) coinfection among cases in the re-emergence of mpox to inform national and global response. METHODS: We conducted a national descriptive and case-control study on …

  • Economic evaluation of novel Mycobacterium tuberculosis specific antigen-based skin tests for detection of TB infection

    Open AccessLara Goscé, Kasim Allel et al.ARTICLEPLOS Global Public Health2023

    Evidence on the economic impact of novel skin tests for tuberculosis infection (TBST) is scarce and limited by study quality. We used estimates on the cost-effectiveness of the use of TBST compared to current tuberculosis infection (TBI) tests to assess whether TBST are affordable and feasible to implement under different country contexts. A Markov model parametrised to Brazil, South Africa and the UK was developed to compare the cost-effectivene…

  • The Lancet Nigeria Commission

    Open AccessIbrahim Abubakar, Sarah L Dalglish et al.ARTICLEThe Lancet2022

    Health is central to the development of any country. Nigeria’s gross domestic product is the largest in Africa, but its per capita income of about ₦770 000 (US$2000) is low with a highly inequitable distribution of income, wealth, and therefore, health. It is a picture of poverty amidst plenty. Nigeria is both a wealthy country and a very poor one. About 40% of Nigerians live in poverty, in social conditions that create ill health, and with the e…

  • Seroprevalence of Sars-CoV-2 in four states of Nigeria in October 2020

    Open AccessRosemary Audu, Kristen A Stafford et al.ARTICLEPLOS Global Public Health2022

    The observed epidemiology of SARS-CoV-2 in sub-Saharan Africa has varied greatly from that in Europe and the United States, with much lower reported incidence. Population-based studies are needed to estimate true cumulative incidence of SARS-CoV-2 to inform public health interventions. This study estimated SARS-CoV-2 seroprevalence in four selected states in Nigeria in October 2020. We implemented a two-stage cluster sample household survey in fo…

  • Hepatitis B Virus

    Open AccessPhilippa C Matthews, Tongai Maponga et al.ARTICLEPLOS Global Public Health2022

    Hepatitis B virus (HBV) is a blood-borne virus that establishes chronic liver infection, associated with potential complications of cirrhosis and/or hepatocellular carcinoma (HCC). As such, it poses a major threat to global public health, accounting for 300 million chronic infections, and more than 500,000 deaths each year It can also be regarded as a 'syndemic' challenge-namely, as one component of multiple, complex interacting health and social…

  • Covid-19 mortality rate and its associated factors during the first and second waves in Nigeria

    Open AccessKelly Elimian, Anwar Musah et al.ARTICLEPLOS Global Public Health2022

    COVID-19 mortality rate has not been formally assessed in Nigeria. Thus, we aimed to address this gap and identify associated mortality risk factors during the first and second waves in Nigeria. This was a retrospective analysis of national surveillance data from all 37 States in Nigeria between February 27, 2020, and April 3, 2021. The outcome variable was mortality amongst persons who tested positive for SARS-CoV-2 by Reverse-Transcriptase Poly…

  • HIV self-testing

    Open AccessAnkur Gupta-Wright, Ruanne V Barnabas et al.ARTICLEBMJ Global Health2021

    box HIV self-testing (HIVST) has shifted the paradigm for HIV testing, the first step in the care continuum. Although HIVST, whereby the person performs the test and interprets the results, was conceived early in the HIV epidemic, wider access to HIVST in low-income and middle-income countries (LMICs) is a recent phenomenon. A decade ago, large-scale HIVST use was limited due to concerns about accuracy, feasibility and safety. Through coordinatio…

  • Lessons from co-production of evidence and policy in Nigeria’s Covid-19 response

    Open AccessIbrahim Abubakar, Sarah L Dalglish et al.ARTICLEBMJ Global Health2021

    In February 2020, Nigeria faced a potentially catastrophic COVID-19 outbreak due to multiple introductions, high population density in urban slums, prevalence of other infectious diseases and poor health infrastructure. As in other countries, Nigerian policymakers had to make rapid and consequential decisions with limited understanding of transmission dynamics and the efficacy of available control measures. We present an account of the Nigerian C…

  • The impact of rural residence and HIV infection on poor tuberculosis treatment outcomes in a large urban hospital

    Open AccessAishatu L Adamu, Muktar H Aliyu et al.ARTICLEInternational Journal for Equity…2018

    Rural residents attending a large Nigerian TB clinic are at increased risk of having poor treatment outcomes, and this risk is amplified among those that are HIV-negative. Our findings indicate that rural coverage of HIV services may be better than TB services. These findings highlight the importance of expanding coverage of TB services to ensure prompt diagnosis and commencement of treatment, especially among rural-dwellers in resource-limited s…
