ABSTRACT
BACKGROUND: The routine surveillance of asymptomatic malaria using nucleic acid-based amplification tests is essential in obtaining reliable data that would inform malaria policy formulation and the implementation of appropriate control measures. METHODS: In this study, the prevalence rate and the dynamics of Plasmodium species among asymptomatic children (n = 1697) under 5 years from 30 communities within the Hohoe municipality in Ghana were determined. RESULTS AND DISCUSSION: The observed prevalence of Plasmodium parasite infection by polymerase chain reaction (PCR) was 33.6% (571/1697), which was significantly higher compared to that obtained by microscopy [26.6% (451/1697)] (P < 0.0001). Based on species-specific analysis by nested PCR, Plasmodium falciparum infection [33.6% (570/1697)] was dominant, with Plasmodium malariae, Plasmodium ovale and Plasmodium vivax infections accounting for 0.1% (1/1697), 0.0% (0/1697), and 0.0% (0/1697), respectively. The prevalence of P. falciparum infection among the 30 communities ranged from 0.0 to 82.5%. Following artesunate-amodiaquine (AS + AQ, 25 mg/kg) treatment of a sub-population of the participants (n = 184), there was a substantial reduction in Plasmodium parasite prevalence by 100% and 79.2% on day 7 based on microscopy and nested PCR analysis, respectively. However, there was an increase in parasite prevalence from day 14 to day 42, with a subsequent decline on day 70 by both microscopy and nested PCR. For parasite clearance rate analysis, we found a significant proportion of the participants harbouring residual Plasmodium parasites or parasite genomic DNA on day 1 [65.0% (13/20)], day 2 [65.0% (13/20)] and day 3 [60.0% (12/20)] after initiating treatment. Of note, gametocyte carriage among participants was low before and after treatment. CONCLUSION: Taken together, the results indicate that a significant number of individuals could harbour residual Plasmodium parasites or parasite genomic DNA after treatment. The study demonstrates the importance of routine surveillance of asymptomatic malaria using sensitive nucleic acid-based amplification techniques.

INTRODUCTION: Over the past two decades, there have been several global interventions including the Sustainable Development Goals (SDGs), aimed at improving health outcomes. Despite efforts by countries to achieve the SDG targets, mental health challenges remain major public health concerns globally. We examined the prevalence and predictors of depression, anxiety, and stress as well as the comorbidities of these mental health issues among adults. MATERIALS AND METHODS: This was a community-based cross-sectional study conducted among 2456 adults in four districts of the Volta Region of Ghana using data from the UHAS-Yonsei University Partnership Project. We analysed the data using frequency, percentage, mean, standard deviation, correlation, and binary logistic regression. RESULTS: Overall, 51.8% of the participants had at least one of the mental health issues examined. The prevalence of a mental health issue was 25.2%, 53.3%, and 9.7% for depression, anxiety, and stress respectively. Participants constituting 8.3% experienced all three mental health issues as comorbidities. Participants' level of formal education and income significantly predicted depression, anxiety, and stress respectively at the multivariable level. Adults with a tertiary level of education were, for instance, 68% (AOR = 0.32, 95%CI = 0.15-0.66), 65% (AOR = 0.35, 95%CI = 0.17-0.73), and 50% (AOR = 0.50, 95%CI = 0.33-0.76) less likely to experience depression, anxiety, and stress, respectively compared with those who had no formal education. CONCLUSION: The majority of our study participants either experienced depression, anxiety, or stress. There were quite high comorbidities of the mental health issues among the adult population. To accelerate progress towards the achievement of SDG 3.4 target of promoting mental health and wellbeing for all by the year 2030, there is a need for effective implementation of the country's 2012 Mental Health Act which makes provisions for the establishment of a Mental Health Fund. This could improve the financial circumstances of indigenes as income has been realised in the present study as an important factor influencing depression, anxiety, and stress among the adult population.

BACKGROUND: Eye injuries are one of the most common work-related injuries among certain occupations, including welders. The aim of this study was to determine the prevalence and factors influencing eye injuries among welders in Accra, Ghana. METHODS: In a cross-sectional study, we recruited 382 welders in Accra from two welding sites. Systematic sampling was used to select participants. A pretested semistructured questionnaire was used to collect demographic information, history of eye injuries, ownership, and use of eye protective equipment and workplace characteristics. Bivariate and multivariate logistic regressions at 5% level of significance were used to determine factors influencing eye injuries. Data were entered into Microsoft excel and exported to Stata 16/MP for analysis. RESULTS: We found 59.7% of welders engaged in electric/arc welding and 40.3% in gas welding. Overall prevalence of eye injuries was 47.9%, higher among electric/arc welders (73.7%) compared to gas welders (9.7%). Factors associated with eye injuries were engaging in gas welding [AOR: 0.08, 95% CI: 0.04-0.16], higher monthly income [AOR = 5.26; 95% CI: 1.72-16.09], nonuse of eye PPE while working [AOR = 1.86; 95% CI: 1.02-3.43], and no training on the use of eye personal protective equipment [AOR = 2.17; 95% CI: 1.07-4.38]. CONCLUSION: There is high prevalence of welding-related eye injuries among electric welders. Gas welding, high monthly income, nonuse of eye protective equipment, and inadequate training on the use of eye protective equipment were significantly associated with eye injuries. Health policies should be implemented to ensure all welders use eye personal protective equipment.
ABSTRACT
BACKGROUND: The impact of HIV on TB, and the implications for TB control, has been acknowledged as a public health challenge. It is imperative therefore to assess the burden of HIV on TB patients as an indicator for monitoring the control efforts of the two diseases in this part of the world. This study aimed at determining the burden of HIV infection in TB patients. METHODS: We conducted a retrospective review of TB registers in five districts of the Volta Region of Ghana. Prevalence of TB/HIV co-infection was determined. Bivariate and multivariate logistic regression were used to identify the predictors of HIV infection among TB patients and statistical significance was set at p-value <0.05. RESULTS: Of the 1772 TB patients, 1633 (92.2%) were tested for HIV. The overall prevalence of TB/HIV co-infection was (18.2%; 95% CI: 16.4-20.1). The prevalence was significantly higher among females (24.1%; 95%CI: 20.8-27.7), compared to males (15.1%; 95% CI: 13.1-17.4) (p < 0.001) and among children <15 years of age (27.0%; 95% CI: 18.2-38.1), compared to the elderly ≥70 years (3.5%; 95% CI: 1.6-7.4) (p < 0.001). Treatment success rate was higher among patients with only TB (90%; 95% CI: 88.1-91.5) than among TB/HIV co-infected patients (77.0%; 95% CI: 71.7-81.7) (p < 0.001). Independent predictors of HIV infection were found to be: being female (AOR: 1.79; 95% CI: 1.38-2.13; p < 0.001); smear negative pulmonary TB (AOR: 1.84; 95% CI: 1.37-2.47; p < 0.001); and patients registered in Hohoe, Kadjebi, and Kpando districts with adjusted odds ratios of 1.69 (95% CI: 1.13-2.54; p = 0.011), 2.29 (95% CI: 1.46-3.57; p < 0.001), and 2.15 (95% CI: 1.44-3.21; p < 0.001) respectively. Patients ≥70 years of age and those registered in Keta Municipal were less likely to be HIV positive with odds ratios of 0.09 (95% CI: 0.04-0.26; p < 0.001) and 0.62 (95% CI: 0.38-0.99; p = 0.047) respectively. CONCLUSION: TB/HIV co-infection rate in five study districts of the Volta region is quite high, occurs more frequently in female patients than males; among smear negative pulmonary TB patients, and children <15 years of age. Findings also demonstrate that HIV co-infection affects TB treatment outcomes adversely. Strengthening the TB/HIV collaborative efforts is required in order to reduce the burden of co-infection in patients.
