Registration status, mercury exposure biomarkers, and neuropsychological assessment of artisanal and small-scale gold miners (ASGM) from the Western Region of Ghana.

The artisanal and small-scale gold mining (ASGM) sector is estimated to be the largest anthropogenic source of mercury pollution worldwide, and not surprisingly human exposures in this sector are amongst the highest of all population groups. While formalization of the sector has been proposed as a solution to help improve health and safety within ASGM sites, there are few empirical studies in support of this notion. The objective of this study was to assess if individuals working in ASGM sites that are registered have reduced mercury exposures and better neuropsychological scores than workers from unregistered sites. To achieve this objective, we studied biological samples (urine, hair) and survey data from a study of 404 ASGM workers (of which, 295 worked in registered ASGM sites) conducted in Tarkwa (Ghana) in 2014. Between miners working in registered and unregistered sites, there were few differences in socio-demographic characteristics. Median urinary mercury concentration (specific gravity-corrected) among those from unregistered mines was nearly 3-fold higher than those from the registered mines (18.5 versus 6.6 µg/L), and in the overall population the median concentration was 10.0 µg/L, and ranged from 0.3 to 2499 µg/L. Mercury biomarkers varied across ASGM work categories (e.g., those who burned or amalgamated had the highest) and users of personal protective equipment. Nearly 30% of the study population indicated having some challenges concerning, for example, reduced appetite, hair loss, or excess salivation. Ataxia and rigidity of gait were absent in most of the participants, and for those with slight, moderate, or marked responses, there were no differences between miners from registered and unregistered sites, across work groups, as well as in reference to mercury biomarker measures. For the pencil tapping, Frostig, matchbox, and Wechsler tests, no striking differences were found though a correlation was found between urinary mercury levels and matchbox scores among those who amalgamate and burn, and scores were similar to past studies using the same tests in ASGM sites. We believe this is the first study to compare mercury exposures and neuropsychological test results between miners from registered and unregistered ASGM sites. In doing so, the research findings provide the necessary evidence for stakeholders and parties of the Minamata Convention considering various response options to help fulfill their obligations.

Satisfaction levels and associated influencing factors among inpatients and outpatients with breast cancer at a tertiary health facility in Ghana.

Objectives: To uncover variables linked to breast cancer patient satisfaction in order to improve policy choices and actions for breast cancer care in Ghana. Design: We employed a cross-sectional design using a quantitative approach. Setting: The Radiotherapy, Oncology and Surgery Departments of the Korle Bu Teaching Hospital, Accra. Participants: Inpatient and outpatient breast cancer patients. Main outcome measures: The level of inpatient and outpatient satisfaction was measured using descriptive and inferential statistical analyses. The Shapiro-Wilk test was employed to assess normality, while the Heckman selection model assessed significance with outcomes of interest. Results: A total of 636 participants, with a mean age of 52.64±14.07 years, were recruited. The measured inpatient and outpatient levels of satisfaction out of 100 were 74.06±7.41 and 49.99±1.00 respectively, while the self-reported satisfaction levels out of 5 were 4.22±0.63 and 4.11±0.85 respectively. The level of inpatient satisfaction was significantly influenced by age, marital status, income level, and number of previous facilities visited (p<0.05). Outpatient satisfaction level was significantly associated with place of residence and income level (p<0.05). Conclusions: The study offers insight into the satisfaction levels of breast cancer patients receiving inpatient and outpatient services at the largest tertiary referral centre and teaching hospital in Ghana, as well as the factors influencing attendance and satisfaction levels. Understanding and improving breast cancer patients' levels of satisfaction is a way that providers can safeguard their emotional well-being. Improvement in patient satisfaction at our institution among outpatients is an area for future growth. Funding: Gardner-Holt Women's Health Grant program, Centre for Global Surgery 2021.

Comparative analysis of clinical characteristics of COVID-19 among vaccinated and unvaccinated patients in a major treatment facility in Ghana.

Objectives: To compare clinical characteristics of COVID-19 among vaccinated and unvaccinated patients in a major treatment facility in Ghana. Design: A retrospective study drawing on data from COVID-19 patients' records visiting the facility from March 2021 to December 2021. Setting: Ghana Infectious Disease Centre, Ga East Municipality, Greater Accra Region, Ghana. Participants: In-patients and outpatients who reported to the facility from 1st March 2021 to December 2021 were included in the study, and patients with missing data on vaccination were excluded. Outcome measures: underlying conditions, symptoms, case management information, hospital service rendered (OPD, HDU or ICU), length of hospital stay, treatment outcome. Results: The study included 775 patient records comprising 615 OPD and 160 hospitalised cases. Less than one-third (26.25%; 42) of the patients hospitalised were vaccinated compared to almost 40.0% (39.02%; 240) of the patients seen at the OPD. Vaccinated individuals were nearly three times (aOR = 2.72, 95%CI:1.74-4.25) more likely to be managed on an outpatient basis as compared to the unvaccinated. The death rate among the vaccinated group and the unvaccinated were (0.71%; 2) and (3.45%; 17), respectively, with a significant reduction in the risk of dying among the vaccinated compared to the unvaccinated (aOR = 0.13, 95%CI: 0.028 0.554). Conclusions: Less than half of the in-patient and OPD patients were vaccinated. Mild infections, fewer days of hospitalisation, outpatient treatment and higher chances of survival were associated with being vaccinated against SARS-CoV-2. Prudent measures should be implemented to encourage the general public to take up SARS-CoV-2 vaccines. Funding: None declared.

Home-Based Remedies to Prevent COVID-19-Associated Risk of Infection, Admission, Severe Disease, and Death: A Nested Case-Control Study.

Objective: This study aimed at determining the various types of home-based remedies, mode of administration, prevalence of use, and their relevance in reducing the risk of infection, hospital admission, severe disease, and death. Methods: The study design is an open cohort of all participants who presented for testing for COVID-19 at the Infectious Disease Treatment Centre (Tamale) and were followed up for a period of six weeks. A nested case-control study was designed. Numerical data were analysed using STATA version 14, and qualitative data were thematically analysed. Results: A total of 882 participants made up of 358 (40.6%) cases and 524 (59.4%) unmatched controls took part in the study. The prevalence of usage of home-based remedies to prevent COVID-19 was 29.6% (n = 261). These include drinks (34.1% (n = 100)), changes in eating habits/food (33.8% (n = 99)), physical exercise (18.8% (n = 55)), steam inhalation (9.9% (n = 29)), herbal baths (2.7% (n = 8)), and gurgle (0.7 (n = 2)). Participants who practiced any form of home-based therapy were protected from SARS-CoV-2 infection (OR = 0.28 (0.20-0.39)), severe/critical COVID-19 (OR = 0.15 (0.05-0.48)), hospital admission (OR = 0.15 (0.06-0.38)), and death (OR = 0.31 (0.07-1.38)). Analysis of the various subgroups of the home-based therapies, however, demonstrated that not all the home-based remedies were effective. Steam inhalation and herbal baths were associated with 26.6 (95% CI = 6.10-116.24) and 2.7 (95% CI = 0.49-14.78) times increased risk of infection, respectively. However, change in diet (AOR = 0.01 (0.00-0.13)) and physical exercise (AOR = 0.02 (0.00-0.26)) remained significantly associated with a reduced risk of infection. We described results of thematic content analysis regarding the common ingredients in the drinks, diets, and other home-based methods administered. Conclusion: Almost a third of persons presenting for COVID-19 test were involved in some form of home-based remedy to prevent COVID-19. Steam inhalation and herbal baths increased risk of COVID-19 infection, while physical exercise and dietary changes were protective against COVID-19 infection and hospital admission. Future protocols might consider inclusion of physical activity and dietary changes based on demonstrated health gains.
