The disadvantaged populations eGFR (estimated glomerular filtration rate) epidemiology (DEGREE) study was designed to gain insight into the burden of chronic kidney disease (CKD) of undetermined cause (CKDu) using standard protocols to estimate the general-population prevalence of low eGFR internationally. Therefore, we estimated the age-standardized prevalence of eGFR under 60 ml/min per 1.73m in adults aged 18-60, excluding participants with commonly known causes of CKD; an ACR (albumin/creatinine ratio) over 300 mg/g or equivalent, or self-reported or measured (HT) hypertension or (DM) diabetes mellitus, stratified by sex and location.

Article Synopsis
  • The DEGREE study explored the impact of chronic kidney disease of undetermined cause (CKDu) globally by analyzing the prevalence of low estimated glomerular filtration rate (eGFR) in adults aged 18-60, focusing on participants without known CKD causes.
  • The study included data from 60,964 participants across 43 areas in 14 countries collected from 2007 to 2023, revealing the highest CKDu prevalence in rural areas of Uddanam, India, and Northwest Nicaragua (14%).
  • The findings indicate that CKDu is notably prevalent in specific regions, especially within Central America and South Asia, prompting the need for global monitoring while acknowledging the potential existence of unidentified disease clusters elsewhere.

Supplementary methods of mortality surveillance are needed in settings with incomplete death registration. Local perceptions of mortality levels might be useful indicators of excess deaths. Early in the COVID-19 pandemic, we developed a survey question asking respondents to evaluate the recent frequency of funerals in their community relative to a pre-pandemic baseline.

We investigated behavioral responses to COVID-19 in Malawi, where a first wave of the pandemic occurred between June and August 2020. Contrary to many countries on the African continent, the Government of Malawi did not impose a lockdown or a stay-at-home order in response to the initial spread of SARS-CoV-2. We hypothesized that, in the absence of such requirements to restrict social interactions, individuals would primarily seek to reduce the risk of SARS-CoV-2 transmission during contacts, rather than reduce the extent of their social contacts.

Article Synopsis
  • * This study employed eight focus groups in Malawi to explore the perspectives of breastfeeding women, couples, and healthcare providers on the collection of these "non-invasive" biosamples, revealing varying perceptions of invasiveness.
  • * Findings indicate a disconnect between biomedical views of "non-invasive" sampling and community concerns, underscoring the need for researchers to address therapeutic misconceptions and engage openly with the communities involved in biosampling.
