Antihypertensive Medications and Eczematous Dermatitis in Older Adults.
IMPORTANCE: Rates of physician-diagnosed eczema have been increasing among older adults, but little is known regarding the pathophysiologic processes and best treatments in this subgroup. Preliminary data suggest that medications-antihypertensive medications in particular-may contribute to eczematous dermatitis; however, there are limited population-based data on the proportion of eczematous dermatitis diagnoses among older adults that may be attributed to antihypertensive drugs. OBJECTIVES: To determine whether antihypertensive drug use is associated with eczematous dermatitis in older adults. DESIGN, SETTINGS, AND PARTICIPANTS: This was a longitudinal cohort study of a population-based sample of individuals 60 years and older without a diagnosis of eczematous dermatitis at baseline. It was conducted at primary care practices participating in The Health Improvement Network in the United Kingdom from January 1, 1994, to January 1, 2015. Data analyses were performed from January 6, 2020, to February 6, 2024. EXPOSURE: Exposure date by first prescription for an antihypertensive drug within each drug class. MAIN OUTCOME MEASURES: Newly active eczematous dermatitis was based on the first date for 1 of the 5 most common eczema codes used in a previously validated algorithm. RESULTS: Among the total study sample of 1 561 358 older adults (mean [SD] age, 67 [9] years; 54% female), the overall prevalence of eczematous dermatitis was 6.7% during a median (IQR) follow-up duration of 6 (3-11) years. Eczematous dermatitis incidence was higher among participants receiving antihypertensive drugs than those who did not (12 vs 9 of 1000 person-years of follow-up). Adjusted Cox proportional hazard models found that participants who received any antihypertensive drugs had a 29% increased hazard rate of any eczematous dermatitis (hazard ratio [HR], 1.29; 95% CI, 1.26-1.31). When assessing each antihypertensive drug class individually, the largest effect size was observed for diuretic drugs (HR, 1.21; 95% CI, 1.19-1.24) and calcium channel blockers (HR, 1.16; 95% CI, 1.14-1.18), and the smallest effect sizes were for angiotensin-converting enzyme inhibitors (HR, 1.02; 95% CI, 1.00-1.04) and β-blockers (HR, 1.04; 95% CI, 1.02-1.06). CONCLUSIONS AND RELEVANCE: This cohort study found that antihypertensive drugs were associated with a small increased rate of eczematous dermatitis, with effect sizes largest for calcium channel blockers and diuretic drugs, and smallest for angiotensin-converting enzyme inhibitors and β-blockers. Although additional research is needed to understand the mechanisms underlying the association, these data could be helpful to clinicians to guide management when a patient presents with eczematous dermatitis in older age
Good while it lasted? Estimating the long-term and withdrawal effects of results-based financing in Malawi on maternal care utilisation using routine data.
OBJECTIVES: This study aimed to evaluate the effect of introduction and subsequent withdrawal of the Results-based Financing for Maternal and Newborn Health Initiative (RBF4MNH) in Malawi on utilisation of facility-based childbirths, antenatal care (ANC) and postnatal care (PNC). DESIGN: A controlled interrupted time series design was used with secondary data from the Malawian Health Management Information System. SETTING: Healthcare facilities at all levels identified as providing maternity services in four intervention districts and 20 non-intervention districts in Malawi. PARTICIPANTS: Routinely collected, secondary data of total monthly service utilisation of facility-based childbirths, ANC and PNC services. INTERVENTIONS: The intervention is the RBF4MNH initiative, introduced by the Malawian government in 2013 to improve maternal and infant health outcomes and withdrawn in 2018 after ceasing of donor funding. OUTCOME MEASURES: Differences in total volume and trends of utilisation of facility-based childbirths, ANC and PNC services, compared between intervention versus non-intervention districts, for the study period of 90 consecutive months. RESULTS: No significant effect was observed, on utilisation trends for any of the three services during the first 2.5 years of intervention. In the following 2.5 years after full implementation, we observed a small positive increase for facility-based childbirths (+0.62 childbirths/month/facility) and decrease for PNC (-0.55 consultations/month/facility) trends of utilisation respectively. After withdrawal, facility-based childbirths and ANC consultations dropped both in immediate volume after removal (-10.84 childbirths/facility and -20.66 consultations/facility, respectively), and in trends of utilisation over time (-0.27 childbirths/month/facility and -1.38 consultations/month/facility, respectively). PNC utilisation levels seemed unaffected in intervention districts against a decline in the rest of the country. CONCLUSIONS: Concurrent with wider literature, our results suggest that effects of complex health financing interventions, such as RBF4MNH, can take a long time to be seen. They might not be sustained beyond the implementation period if measures are not adopted to reform existing health financing structures
Addressing future food demand in The Gambia: can increased crop productivity and climate change adaptation close the supply-demand gap?
UNLABELLED: With rising demand for food and the threats posed by climate change, The Gambia faces significant challenges in ensuring sufficient and nutritious food for its population. To address these challenges, there is a need to increase domestic food production while limiting deforestation and land degradation. In this study, we modified the FABLE Calculator, a food and land-use system model, to focus on The Gambia to simulate scenarios for future food demand and increasing domestic food production. We considered the impacts of climate change on crops, the adoption of climate change adaptation techniques, as well as the potential of enhanced fertiliser use and irrigation to boost crop productivity, and assessed whether these measures would be sufficient to meet the projected increase in food demand. Our results indicate that domestic food production on existing cropland will not be sufficient to meet national food demand by 2050, leading to a significant supply-demand gap. However, investments in fertiliser availability and the development of sustainable irrigation infrastructure, coupled with climate change adaptation strategies like the adoption of climate-resilient crop varieties and optimised planting dates, could halve this gap. Addressing the remaining gap will require additional strategies, such as increasing imports, expanding cropland, or prioritising the production of domestic food crops over export crops. Given the critical role imports play in The Gambia's food supply, it is essential to ensure a robust flow of food imports by diversifying partners and addressing regional trade barriers. Our study highlights the urgent need for sustained investment and policy support to enhance domestic food production and food imports to secure sufficient and healthy food supplies amidst growing demand and climate change challenges.

Interventions that prevent or respond to intimate partner violence against women and violence against children: a systematic review.
Efforts to prevent or respond to intimate partner violence (IPV) and violence against children (VAC) are still disparate worldwide, despite increasing evidence of intersections across these forms of violence. We conducted a systematic review to explore interventions that prevent or respond to IPV and VAC by parents or caregivers, aiming to identify common intervention components and mechanisms that lead to a reduction in IPV and VAC. 30 unique interventions from 16 countries were identified, with 20 targeting both IPV and VAC. Key mechanisms for reducing IPV and VAC in primary prevention interventions included improved communication, conflict resolution, reflection on harmful gender norms, and awareness of the adverse consequences of IPV and VAC on children. Therapeutic programmes for women and children who were exposed to IPV facilitated engagement with IPV-related trauma, increased awareness of the effects of IPV, and promoted avoidance of unhealthy relationships. Evidence gaps in low-income and middle-income countries involved adolescent interventions, post-abuse interventions for women and children, and interventions addressing both prevention and response to IPV and VAC. Our findings strengthen evidence in support of efforts to address IPV and VAC through coordinated prevention and response programmes. However, response interventions for both IPV and VAC are rare and predominantly implemented in high-income countries. Although therapeutic programmes for parents, caregivers, and children in high-income countries are promising, their feasibility in low-income and middle-income countries remains uncertain. Despite this uncertainty, there is potential to improve the use of health services to address IPV and VAC together
Temperature frequency and mortality: Assessing adaptation to local temperature.
Assessing the association between temperature frequency and mortality can provide insights into human adaptation to local ambient temperatures. We collected daily time-series data on mortality and temperature from 757 locations in 47 countries/regions during 1979-2020. We used a two-stage time series design to assess the association between temperature frequency and all-cause mortality. The results were pooled at the national, regional, and global levels. We observed a consistent decrease in the risk of mortality as the normalized frequency of temperature increases across the globe. The average increase in mortality risk comparing the 10th to 100th percentile of normalized frequency was 13.03% (95% CI: 12.17-13.91), with substantial regional differences (from 4.56% in Australia and New Zealand to 33.06% in South Europe). The highest increase in mortality was observed for high-income countries (13.58%, 95% CI: 12.56-14.61), followed by lower-middle-income countries (12.34%, 95% CI: 9.27-15.51). This study observed a declining risk of mortality associated with higher temperature frequency. Our findings suggest that populations can adapt to their local climate with frequent exposure, with the adapting ability varying geographically due to differences in climatic and socioeconomic characteristics
A flow cytometry-based assay to determine the ability of anti-Streptococcus pyogenes antibodies to mediate monocytic phagocytosis in human sera.
Streptococcus pyogenes, commonly referred to as Group A Streptococcus (Strep A), causes a spectrum of diseases, with the potential to progress into life-threatening illnesses and autoimmune complications. The escalating threat of antimicrobial resistance, stemming from the prevalent reliance on antibiotic therapies to manage Strep A infections, underscores the critical need for the development of disease control strategies centred around vaccination. Phagocytes play a critical role in controlling Strep A infections, and phagocytosis-replicating assays are essential for vaccine development. Traditionally, such assays have employed whole-blood killing or opsonophagocytic methods using HL-60 cells as neutrophil surrogates. However, assays mimicking Fcγ receptors- phagocytosis in clinical contexts are lacking. Therefore, here we introduce a flow cytometry-based method employing undifferentiated THP-1 cells as monocytic/macrophage model to swiftly evaluate the ability of human sera to induce phagocytosis of Strep A. We extensively characterize the assay's precision, linearity, and quantification limit, ensuring robustness. By testing human pooled serum, the assay proved to be suitable for the comparison of human sera's phagocytic capability against Strep A. This method offers a valuable complementary assay for clinical studies, addressing the gap in assessing FcγR-mediated phagocytosis. By facilitating efficient evaluation of Strep A -phagocyte interactions, it may contribute to elucidating the mechanisms required for the prevention of infections and inform the development of future vaccines and therapeutic advancements against Strep A infections
Exploring the consent process among pregnant and breastfeeding women taking part in a maternal vaccine clinical trial in Kampala, Uganda: a qualitative study.
BACKGROUND: The involvement of pregnant women in vaccine clinical trials presents unique challenges for the informed consent process. We explored the expectations and experiences of the pregnant women, spouses/partners, health workers and stakeholders of the consent process during a Group B Streptococcus maternal vaccine trial. METHODS: We interviewed 56 participants including pregnant women taking part in the trial, women not in the trial, health workers handling the trial procedures, spouses, and community stakeholders. We conducted 13 in-depth interviews and focus group discussions with 23 women in the trial, in-depth interviews with 5 spouses, and 5 women not in the trial, key informant interviews with 5 health workers and 5 other stakeholders were undertaken. RESULTS: Decision-making by a pregnant woman to join a trial was done in consultation with spouse, parents, siblings, or trusted health workers. Written study information was appreciated by all but they suggested the use of audio and visual presentation to enhance understanding. Women stressed the need to ensure that their male partners received study information before their pregnant partners joined a clinical trial. Confidentiality in research was emphasised differently by individual participants; while some emphasised it for self, others were keen to protect their family members from being exposed, for allowing them to be involved in research. However, others wanted their community participation to be acknowledged. CONCLUSION: We found that pregnant women make decisions to join a clinical trial after consulting with close family. Our findings suggest the need for an information strategy which informs not only the pregnant woman, but also her family about the research she is invited to engage in
Israeli necropolitics and the pursuit of health justice in Palestine.
We abhor the continuation and acceleration of the Israeli state's systemic violence against the Palestinian people. We reassert that resolution of the settler colonial root causes of violence in Palestine is central to the pursuit of justice and peace.
The moral foundations of global health and medical practice require us to prioritise and foreground oppressed realities, and to practise epistemic resistance.
Framing Palestinian violence on October 7 as provocation and Israeli violence as response is ahistoric and indicates indifference to the everyday violence experienced by Palestinians. The Israeli state practises both fast violence against Palestinians, while simultaneously creating the conditions for their ‘slow death’.
The systematic targeting and destruction of the health system and healthcare workers in Gaza has been central to Israel's military strategy, while many Israeli officials have expressed clear genocidal intent.
The occupation of Palestine demonstrates the horrors of Israeli necropolitics, which leads to the creation of 'death-worlds' in which people survive and resist in perpetual proximity to death
A novel hypothesis-generating approach for detecting phenotypic associations using epigenetic data.
Aim: Hypotheses about what phenotypes to include in causal analyses, that in turn can have clinical and policy implications, can be guided by hypothesis-free approaches leveraging the epigenome, for example. Materials & methods: Minimally adjusted epigenome-wide association studies (EWAS) using ALSPAC data were performed for example conditions, dysmenorrhea and heavy menstrual bleeding (HMB). Differentially methylated CpGs were searched in the EWAS Catalog and associated traits identified. Traits were compared between those with and without the example conditions in ALSPAC. Results: Seven CpG sites were associated with dysmenorrhea and two with HMB. Smoking and adverse childhood experience score were associated with both conditions in the hypothesis-testing phase. Conclusion: Hypothesis-generating EWAS can help identify associations for future analyses
Assessment and Qualitative Comparative Analysis of English Local Authority Joint Health and Wellbeing Strategies to Improve Health under Austerity Conditions, 2013–2017
Background. Local government is important for health equity because local policies often affect place‐based health, health equity, and their wider social determinants of health. In England, local governments must produce Joint Health and Wellbeing (JH&W) Strategies, outlining local strategies for health improvement. These strategies have been produced concurrently with budget cuts to local governments that are associated with adverse health and mortality outcomes. Using a novel approach, we assessed whether English local governments’ strategies for place‐based health and equity help explain why some disadvantaged areas have better mortality trends than others. Methods. We sampled “Joint Health and Wellbeing” (JH&W) Strategies for 20 disadvantaged localities covering the years 2013–2017. We sampled areas to include some with larger and some with smaller budget cuts. We developed a qualitative appraisal process for scoring the extent to which JH&W strategies focused on (i) place‐based social determinants of health and (ii) health equity. Using qualitative comparative analysis, we assessed whether mortality trends might be explained by JH&W scores or wider contextual factors such as budget cuts, population age, and disadvantage. Results. JH&W strategies on place‐based social determinants of health and equity were often underdeveloped. Only a minority of strategies were highly rated (i.e., scoring >2 out of 3) for addressing social inequalities of health (n = 6), and even fewer scored highly for place‐based social determinants of health (n = 3). Our qualitative comparative analysis found that external and contextual factors (e.g., budget cuts and disadvantages) offer more plausible explanations than JH&W strategies for place variations in life expectancy trends. Conclusion. Budget cuts and other contextual factors better explain mortality trends than JH&W strategies. This raises concerns about what such strategies can realistically achieve in the face of structural disadvantage and national policies that restrict local spending
