Optometrists play a vital role in detecting and managing glaucoma. This study aims to determine how Ghanaian optometrists manage ocular adverse reactions (OADRs) in patients using antiglaucoma medications. A cross-sectional survey was conducted among 139 licensed optometrists using a pre-tested, semi-structured questionnaire. Data collected included socio-demographic characteristics, reported adverse reactions, and awareness of reporting or management protocols. Descriptive and inferential statistics were performed using SPSS version 25.0. Participants had a mean age of 31.6 ± 5.5 years and an average practice experience of 5.6 ± 4.5 years. Most respondents were female (71.2%), with 36.7% practicing in Greater Accra and 32.0% in private facilities. Nearly all participants (92.8%) reported encountering OADRs to AGMs. The most common symptoms were red eyes (36.0%), stinging (26.1%), burning sensation (25.4%), and itching (8.8%), while clinical signs included conjunctival hyperemia (45.5%), tear film deficiency (26.0%), and iris pigmentation changes (9.8%). Latanoprost (32.2%), timolol (23.7%), travoprost (17.6%), and brimonidine (10.2%) were the medications most frequently associated with these reactions. Optometrists primarily managed cases by switching to alternative medications (41.0%) or adjusting dosage and frequency (9.7%). However, 77.7% reported having no knowledge of existing protocols, and confidence in managing OADRs was moderately low (mean = 2.67 ± 0.49 on a 5-point scale). No significant association was found between OADR reporting and either age (p = 0.616) or years of practice (p = 0.974). These findings highlight that although OADRs are common in glaucoma management, optometrists in Ghana often lack standardized protocols and report low confidence in handling such cases. Targeted professional development and refresher training are needed to strengthen OADRs recognition, reporting, and management, ultimately improving patient eye care.</p>","PeriodicalId":74466,"journal":{"name":"PLOS global public health","volume":"5 10","pages":"e0004251"},"PeriodicalIF":2.5,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12510571/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145260049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Co-infection with these diseases poses a particular challenge, as both are associated with increased production of reactive species that can damage tissues, trigger oxidative stress, and exacerbate disease. To cope with this oxidative insult, cells have a defense system consisting of antioxidant molecules that can terminate the oxygen radical cascade and render toxic metabolites innocuous. However, lack of complete understanding of the pathophysiology of malaria and typhoid fever continues to hinder efforts aimed at eradicating these diseases. In this review, we examine the current understanding of oxidative stress in the context of malaria and typhoid fever, and its implications for disease pathogenesis and treatment. The search and data extraction strategy used in this scoping review involved a structured approach to identify relevant studies related to the topic. Studies were included that investigated ROS production, antioxidant responses, and the effect of pharmacological interventions on oxidative stress markers. The search was conducted using electronic databases, including PubMed, ScienceDirect, and Directory of Open Access Journals (DOAJ), and involved an extensive literature search of studies published between January 2000 and May 2024. The review identified potential avenues for research with evidence that both malaria and typhoid fever elevate oxidative stress levels, which are further exacerbated in co-infections. The endogenous antioxidant response is activated but may not be sufficient to neutralize ROS completely. Moreover, commonly used antimalarial and antibacterial drugs influence oxidative and antioxidant dynamics, which may have implications for treatment efficacy and disease progression. Understanding the oxidative-antioxidant balance in malaria and/or typhoid fever may open new avenues for adjunctive therapies and vaccines targeting oxidative stress. It is thus important to consider the oxidative-antioxidant balance during treatment of malaria and typhoid fever patients.</p>","PeriodicalId":74466,"journal":{"name":"PLOS global public health","volume":"5 10","pages":"e0005193"},"PeriodicalIF":2.5,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12510597/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145260077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a discrete choice experiment (DCE) among HIV-negative sex workers in two high HIV-prevalence Ugandan cities between October and December 2024. Participants selected from alternatives varying by location, waiting time, provider gender, and additional services. A mixed logit model identified the most valued attributes influencing preferences for CAB-LA delivery. We enrolled 251 sex workers (SWs), comprising 52 (20.7%) MSWs. MSWs were more likely to have higher education (26.9% vs 4.5%), while FSWs had been in the industry longer (24 months vs 18 months). PrEP awareness was lower among MSWs than FSWs (86.5% vs. 95.5%, p = 0.027). Overall, 39.4% reported current PrEP use.

In contrast, clinic waiting time and provider gender were considered the least important, with both groups assigning them a relative importance of 4%. Nevertheless, the three top-ranked CAB-LA delivery models prioritized access through private pharmacies or clinics with short waiting times, female or peer providers, and integrated health services. The preferred extra services included psychosocial support, cancer screening, and risk reduction counseling. Expanding injectable PrEP through private sector channels may improve access among SWs.

This situation was further exacerbated by the Tropical Cyclone Freddy, which caused widespread damage to health infrastructure and strained Malawi's limited healthcare resources. Despite the scale of the outbreak, no evaluations were conducted to identify risk factors associated with cholera-related mortality among hospitalized individuals. This study filled that gap by characterizing the clinical and treatment-related factors contributing to cholera mortality in Malawi. A retrospective matched case-control study was conducted in August 2023 across four high-burden cholera districts: Blantyre, Mangochi, Lilongwe, and Nkhatabay. Medical records of 174 laboratory-confirmed cholera patients admitted between March 2022 and September 2023 were reviewed, including 87 matched pairs of deceased (cases) and surviving (controls) patients by age group and district. Data were extracted using a standardized mortality audit tool capturing socio-demographic characteristics, care-seeking behaviour, clinical status, and treatment received. Conditional logistic regression was used to identify factors associated with cholera mortality. Inadequate intravenous fluid management within the first 6 hours of admission was the strongest predictor of mortality (adjusted OR = 45.26, 95% CI: 9.09-225.30, p < 0.001). Other factors such as clinical status on admission showed a trend toward association but did not reach statistical significance.

Age-standardized Years Lived with Disability (YLD) rates were calculated by sex, age subgroups, and sociodemographic index (SDI) quintiles, followed by incidence and prevalence calculations. The study utilized Joinpoint regression, decomposition analysis, slope/concentration index, and sociodemographic attribution analysis to assess the epidemiology of oral disorders. As a result, in 2021, there were 6.22 (3.40-10.57) million YLDs associated with oral disorders among children, adolescents, and young adults globally. Temporal trends indicated a post-pandemic rise in deciduous caries among children. The number of YLDs of caries in children, adolescents, and young adults has all increased despite declining age-standardized YLD rates in 1990-2021 due to population growth in lower-SDI locations. The number and age-standardized YLD rates of periodontal disease and edentulism have risen among adolescents and young adults, exacerbated by worsened epidemiology and population growth. Despite improvements in 2021 compared to 1990, inequalities in periodontal disease burdens persist, disproportionately affecting lower SDI locations. Findings of this study reveal that oral disorder epidemiological metrics among individuals aged 0-39 have generally improved for caries but worsened for periodontal diseases and edentulism. Population growth in lower-SDI locations primarily drove the global increased burdens. SDI-related inequalities disproportionately concentrated periodontal disease burdens in lower-SDI locations.

This review synthesized qualitative evidence that describes self-management of four chronic conditions- HIV, diabetes, chronic kidney disease, and hypertension, including multimorbidity among patients and their carers in SSA. We systematically searched five databases and grey literature for studies published between January 2000 and to March 2025 and conducted a thematic synthesis of findings. Twenty-three studies met inclusion criteria, three of which focused on multimorbidity. Across conditions, patients negotiated self-management based on immediacy of needs and available family support. Patients are motivated to apply biomedical management but are limited by factors such as drug stock-outs and out-of-pocket expenditure. Limited knowledge and low self-efficacy toward self-management of multimorbidity impact decision making and problem solving. We found that diabetes and chronic kidney disease imposed the greatest treatment burden, making them the most challenging conditions for patients to manage. Temporal discontinuation of medications was more prevalent amongst patients with hypertension; and patients with multimorbidity are frequently hypervigilant about their health, more likely to suffer from stress and to seek healthcare. This review synthesised qualitative evidence on self-management of HIV, diabetes, hypertension, and chronic kidney disease in SSA, and considered insights for multimorbidity. Most studies focused on individual conditions, yet our findings reveal strikingly similar challenges across all four conditions: limited health literacy, low self-efficacy, and inadequate structural support. These barriers are likely amplified with multimorbidity, further complicating decision-making and self-management. Addressing these gaps will require context-sensitive interventions that strengthen patient literacy, build confidence to increase patient autonomy and expand the range of resources available to manage chronic disease.</p>","PeriodicalId":74466,"journal":{"name":"PLOS global public health","volume":"5 10","pages":"e0003836"},"PeriodicalIF":2.5,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12510608/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145260015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We developed and applied an individual-based probabilistic framework for mpox incorporating sexual and household contact patterns using data from the National Survey of Sexual Attitudes and Lifestyles 3 (NATSAL3). Individual and population-level reproduction numbers were estimated using setting-specific secondary attack rates. Vaccination impact was assessed across scenarios varying household attack rates, vaccine effectiveness, and distribution strategies. We predict that fewer than 3 out of 100 individuals generated more than one secondary case of clade Ib in England, with a population reproduction number of 0.69 (95%CI 0.66 - 0.71). Individuals reporting both same-sex and opposite sexual contact disproportionately contributed to transmission potential. Increasing household secondary attack rates led to modest increases in the population reproduction number due to individuals with the highest reproduction numbers having lower than average numbers of household contacts. Targeted vaccination, focused on individuals with higher numbers of sexual contacts, consistently outperformed non-targeted strategies, requiring lower vaccine coverage to achieve control even under elevated household transmission. Vaccine effectiveness against infection and onward transmission critically influenced the success of vaccination programs. Despite higher household transmission risks, targeted vaccination remains an effective strategy for controlling mpox clade Ib in England.
