Abstract	Female genital schistosomiasis (FGS) is the gynaecological presentation of Schistosoma haematobium infection, resulting from egg deposition in the female genital tract. Despite the fact that this condition has been reported in the early days of the discovery of S. haematobium in Egypt, its existence has been grossly neglected, causing many women in schistosomiasis-endemic areas to go through a preventable, debilitating, and stigmatizing presentation of FGS. To prevent this, increasing awareness of FGS is necessary for all, especially healthcare providers, to improve the diagnosis, management, and treatment. As proposed by the FAST package project, several healthcare professionals with different specializations are expected to be involved in the management of FGS. It is therefore important that basic updated knowledge on the parasitology of the disease be acquired by healthcare professionals. This review provides basic information necessary to improve the knowledge of FGS among healthcare professionals in areas endemic to schistosomiasis. Armed with these basic details, healthcare professionals can improve their confidence in the management and treatment of FGS, contributing significantly to the control and prevention of FGS in endemic areas.

Abstract	Background: Although, several studies have reported abnormal Mean Corpuscular Volume (MCV) values and anaemia associated with malaria infections with a focus on Plasmodium falciparum among patients with complicated and uncomplicated malaria, none has looked at the association with asymptomatic malaria. This study aimed to assess this association. Methods: We conducted a cross-sectional study using 3 mL of blood samples from 549 children aged 5-17 years attending 5 schools selected in the Volta Region. Semi-structured questionnaires were administered to the children to obtain demographic data. Blood samples were collected to estimate the children's full blood count (FBC) and malaria status. Data obtained were analysed using STATA 15 software. P-values of less than 0.05 were considered statistically significant. Results: Most of the children in this study (49.9%) had normal MCV (81.3-91.3 fL) with an overall malaria prevalence of 55.6 % (95% CI: 51.3-59.8) and anaemia prevalence of 48.6% (95% CI 44.4-52.9). Most anaemic children had normal MCV (81.3-91.3 fL) (49.8, 95% CI 43.7-56.0). The predicted probability of malaria was highly likely among children with normal MCV (81.3-91.3 fL) but with high variability and uncertainty among those with low MCV (<81.3 fL) and high MCV (>91.3 fL). Conclusion: This study shows a reduced predicted probability of malaria among children with low and high MCV, playing a protective function against malaria. Further studies are required to elucidate the interaction.

Abstract	Introduction: Malaria interventions including use of Sulfadoxine-Pyrimethamine as Intermittent Preventive Treatment (IPTp-SP) and distribution of Insecticide Treated Nets (ITNs) have been implemented through ante-natal clinic (ANC) services in Ghana. Yet, the high ANC attendance is not commensurate with the uptake of these interventions, with missed opportunities to deliver the interventions. This study sought to assess the health system factors affecting access and delivery of IPTp-SP and ITN as defined by the Ghana Malaria Policy Guideline to eligible pregnant women attending ANC clinic sessions. Methods: A quantitative cross-sectional study was conducted in the Volta Region of Ghana, with data collected across three levels of health care delivery facilities, including hospitals, health centres and Community-Based Health Planning Service (CHPS) compounds. Data collection included structured observation checklists to document the communication and interaction between the ANC health staff and pregnant women. Additionally, structured questionnaires were used to elicit information on cadre, trainings attended, knowledge and delivery practices of health workers on IPTp-SP and ITN. Stata 16 was used for data analysis, and a defined delivery algorithm was used to compute appropriate and inappropriate delivery practices, using the Ghana policy directive as a guide. Predictors of appropriate delivery were determined using logistic regression analysis. Results: Approximately 97% of the 680 ANC observations had complete information for analysis. Of these, 78% (511/657) were eligible for IPTp-SP after excluding women who have less than 16 weeks of gestation, G6PD deficient, malaria positive and have taken 5 doses of IPTp-SP prior to day of observation. Appropriate delivery of IPTp-SP was 76% (390/511). Despite the availability of SP, 15% (75/511) of all eligible women were not offered the medication and 37% (44/119) of inappropriate delivery was recorded during periods of stock out. ITNs were appropriately delivered to 59% (139) out of 237 eligible women. Thirty-two percent (77/237) of eligible women, mostly continuing ANC clients, were not given ITN despite stock availability. Conclusions: IPTp-SP was appropriately delivered to most of the eligible pregnant women compared to ITN. While stock out of both intervention could account for inappropriate delivery, despite stock availability, IPTp-SP and ITN were not delivered to some eligible women.

Abstract	Infective endocarditis (IE), characterized by inflammation of the endocardial surface of the heart and its valves, results from infections caused by Staphylococcus, Streptococcus and Acinetobacter species and less commonly fungi. Acinetobacter-induced IE is a relatively rare condition with significant morbidity and mortality worldwide. Notably, its mortality rate is greater than that of endocarditis induced by the Haemophilus species, Aggregatibacter actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens and Kingella kingae. Although it is rare, Acinetobacter-induced IE caused by A. baumannii might bring unique therapeutic challenges such as increased antibiotic resistance. Therefore, it is vital to understand perfectly the possible pathophysiologic and antibiotic resistance mechanisms adopted by A. baumannii during IE. This review discusses the probable underlying pathomechanisms involved in A. baumannii-induced IE and highlights the potential antibiotic resistance mechanisms, suggesting therapeutic targets for A. baumannii-induced IE.

Abstract	Background: Ghana has adopted and implemented intermittent preventive treatment using sulfadoxine-pyrimethamine (IPTp-SP) and insecticide-treated nets (ITNs) in an antenatal care (ANC) context to prevent malaria among pregnant women. However, the increased ANC attendance and its frequency facilitated by a free maternal health care policy in Ghana does not correspond with the uptake of IPTp-SP and ITN use among pregnant women. This study sought to elucidate the contextual health system factors influencing the delivery of IPTp-SP and ITN from a related quantitative study conducted in Ghana. Methods: This is the qualitative section of a mixed-methods study design, where audio recorded key informant interviews (KIIs) were conducted with health workers from across health facilities, districts, regional and national health directorates. The KIIs elicited information on health worker knowledge, perceptions, and rationale for the delivery practices of IPTp-SP and ITN revealed in the quantitative findings. The interviews were transcribed and imported into NVivo for analysis. Using the World Health Organization (WHO) Health Systems Framework as the theoretical basis, thematic analysis was conducted under broad themes of the building blocks. Findings are presented in narrative quotes, with a mindmap used to summarize the various health system factors and their interrelated relationship influencing the delivery of IPTp-SP and ITN. Results: Health system factors identified included health staff untrained on malaria delivery directives due to an ineffective trainer of trainer (ToT) system. Additionally, health worker confusion on when to commence SP (at quickening or ≥ 16 weeks) was found to result in delayed start of SP. Stock-outs in facilities due to procurement delays at the national level resulted in missed opportunities to deliver SP to eligible pregnant women at the ANC. Similarly, ITN stock outs led to eligible pregnant women not receiving one at ANC clinics. Conclusion: Poor health worker knowledge on policy directives, a consequence of ineffective training strategy led to delayed delivery of IPTp-SP to eligible pregnant women. Supply chain management challenges related to stock of SP and ITN resulted in missed opportunities to deliver the interventions to pregnant women attending ANC.

Abstract	Intermittent preventive therapy during pregnancy with Sulphadoxine Pyrimethamine (IPTp-SP) is one of the potent strategies for preventing malaria in pregnancy (MiP). Factors such as the pregnant woman's knowledge and very importantly perception or belief about IPTp-SP remains key determinant of IPTp-SP uptake. This study assessed the knowledge and perception of nursing mothers and their uptake of IPTp-SP during pregnancy in the Ho Teaching Hospital. We administered a close-ended questionnaire to 303 nursing mothers and obtained their sociodemographic details as well as information on their knowledge and perception of IPTp-SP utilization. We also reviewed the nursing mothers' antenatal care (ANC) booklets to ascertain the number of times IPTp-SP was taken during pregnancy. Pearson chi-square was used to determine the association between the sociodemographic variable and the categories of knowledge, perception, and uptake of IPTp-SP. Analysis, was done using SPSS, and the p-value of less than 5% was considered statistically significant. Of the 303 nursing mothers sampled in this study, 265(87.5%) had heard about IPTp-SP of which 138(52.1%) had average knowledge of IPTp-SP. A total of 168(63.4%) had poor perception, and 168(64.6%) had adequate uptake (3-4 doses) of IPTp. Education was significantly associated with perception and uptake, with the majority of women who demonstrated excellent perception were those who had tertiary education (7, 6.35%, p = 0.05), and the majority who demonstrated excellent uptake (5 completed doses) were women who had tertiary education (47, 37.9%, p = 0.01). While knowledge was average, perception of IPTp-SP was poor for the majority of the nursing mothers which might have hampered their uptake of IPTp-SP during pregnancy. It is important that continuous assessment of the individual factors affecting the uptake of IPTp-SP be done regularly to curb the negative influences on the uptake of IPTp-SP.

Abstract	Background: This study investigated the knowledge, attitude, and practices of residents in the Ho municipality towards intestinal helminth infections and their prevention. Method: A descriptive cross-sectional study involving questionnaire administration was conducted among randomly sampled residents of the Ho municipality of the Volta Region of Ghana. A minimum sample size of 400 was calculated for subjects using Yamane's formula for population. Pearson's chi-square analysis was done to determine any relationship between sociodemographic characteristics and the categories of knowledge, attitude, and practices. Results from data analysis were computed as frequencies and percentages. Results: Of the 400 participants, 343 (85.7%) were aware of intestinal helminths, but the majority had poor knowledge of its cause despite 50.5% (202) having good knowledge scores. Most participants (331, 82.8%) had a bad attitude toward preventing the disease. Most (335, 83.8%) of the community members still adhered to the poor practice of open defecation with the excuse of unavailable latrines, and some (143, 35.8%) believe that intestinal helminths are nothing to worry about. Conclusion: Health education should address the perceptions towards preventing intestinal helminthiasis and be complemented by making available public lavatories in the municipality to curb the unacceptable practice of open defecation.

Abstract	Background: The control of asymptomatic malaria is considered a key aspect of malaria control. This study aimed to assess the knowledge and perception of asymptomatic malaria among people in Ho municipality of the Volta region. Methods: A descriptive cross-sectional study involving questionnaire administration was conducted among randomly sampled residents of the Ho municipality of the Volta region of Ghana. Using SPSS version 25 statistical software, frequency distributions and proportions were computed for sociodemographic variables while knowledge and perception about asymptomatic malaria were computed into percentages and categorized into three levels based on Bloom's cut-off for further analysis. Findings with p-values <0.05 were considered statistically significant. Results: Among the 200 participants, 197 (98.5%) were aware of malaria. The majority (116 [58.0%]) of the study participants agreed to the possibility of asymptomatic infection, but most (133 [66.5%]) of the community members did not know that asymptomatic individuals can still transmit infections. The majority of the participants (184 [92.0%]) showed interest in getting further education on asymptomatic malaria and a significant majority (180 [90.0%]) expressed a willingness to take treatment after testing positive without showing any symptoms. Conclusions: Asymptomatic malaria control can be achieved through a mass testing and treatment strategy, therefore improving the knowledge and perception about asymptomatic malaria might improve malaria control.
