Association between asymptomatic Plasmodium falciparum malaria infection, anaemia and mean corpuscular volume of school children in the Volta Region of Ghana.

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.

Knowledge and perception of asymptomatic malaria in the Volta region of Ghana.

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.

Knowledge, Attitude, and Practice towards Prevention of Intestinal Helminth Infection among Residents of the Ho Municipality in the Volta Region of Ghana.

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. P < 0.05 is considered statistically significant. 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.

Assessing nursing mothers' knowledge, perceptions and uptake of Sulphadoxine Pyrimethamine (IPTp-SP) during pregnancy in the Ho Teaching Hospital of the Volta Region of Ghana.

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.

Acinetobacter baumannii-induced infective endocarditis: new insights into pathophysiology and antibiotic resistance mechanisms.

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.

Infective endocarditis (IE), known as inflammation of the thin membrane that lines the inside of the heart, results from infections from microbes (e.g., Staphylococcus, Streptococcus and Acinetobacter species and, less commonly, fungi). IE caused by a special microbe called the Acinetobacter species is an uncommon condition with substantial death rates globally. Although it is not common, IE caused by Acinetobacter species, especially A. baumannii, might be difficult to treat due to increased antibiotic resistance. Therefore, it is important to understand the possible disease and antibiotic resistance mechanisms of A. baumannii during IE. This review explains the possible underlying disease mechanisms involved in IE caused by A. baumannii and highlights the potential antibiotic resistance mechanisms, suggesting possible treatment options for IE caused by A. baumannii.

Nutritional aberration and related morphological disorders among patients with human immunodeficiency virus infection on combination antiretroviral therapy (cART) in Ghana: A retrospective study.

Background: Metabolic and nutritional abnormalities among people living with human immunodeficiency virus (PLHIV) have been reported due to either their HIV infection, primary malnutrition caused by insufficient intake or consequences of the ART regimen provided. This study investigated the prevalence and patterns of nutritional abnormalities including morphological changes among HIV patients under combination Antiretroviral Therapy (cART) in the Bia-West District of the Western North Region. Methods: We employed a hospital-based retrospective longitudinal design. Records of 180 patients with HIV infection before and after antiretroviral therapy (ART) initiation were extracted at the Essam Government Hospital. Eligibility criteria included being on treatment without change in regimen for at least one year and without defaulting in scheduled visits. Data extracted included patients' demography, nutritional parameters and medication history. We assessed patients' nutritional characteristics with the subjective global assessment (SGA) tool which includes five components of medical history (weight change, dietary intake, gastrointestinal symptoms, functional capacity & metabolic stress) and two components of physical examination (signs of fat loss and muscle wasting, alterations in fluid balance). Results: Malnutrition, lipodystrophy and body wasting among HIV patients were 48.3% (36.5-62.4), 43.9% (32.6-57.7) and 33.3% (23.6-46.0) respectively. Incremental percentage trends of malnutrition (stage I- 7.4%, stage II -22.4%, stage III-24.7%) and lipodystrophy (Stage I - 22.2%, Stage II - 48.7%, Stage III - 51.9%) were significantly associated with worsening disease status. Patients on AZT+3TC + NVP combined regimen presented with the highest malnutrition [52.9% (28.5-76.1)], lipodystrophy [64.7% (38.6-84.7)] and loss of muscle mass [47.1% (23.9-71.5)]. Long-term ART use was significantly associated with high malnutrition rate (p= 0.02620) and increasing muscle mass loss (p = 0.0040). Conclusion: High malnutrition, lipodystrophy and muscle wasting exist in PLHIV on cART in the Bia-West District. These adverse nutritional effects may be modulated by disease severity, ARV medication and duration.

The parasitology of female genital schistosomiasis.

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.

HIV and malaria prevalence among pregnant women with and without pre-eclampsia at the Atua Government Hospital in Ghana's eastern region.

OBJECTIVE: To evaluate the association of malaria and HIV with pre-eclampsia by evaluating their prevalence among pregnant women. METHODS: Using a case-control study design, we randomly sampled the antenatal records of 125 pregnant women with clinician-diagnosed pre-eclampsia (cases) and 125 others without pre-eclampsia (controls) who visited Atua Government Hospital in the eastern region of Ghana between June 2014 and January 2017. All selected records had available routine HIV and malaria test results and were analyzed statistically. RESULTS: In all 250 records, 122 (48.8%) were HIV positive and 35 (14.0%) had malaria. Of the 122 HIV-positive pregnant women, 29 (23.8%) were cases and 93 (76.2%) were controls; of the 35 women with malaria, one was in the case group (1/35, 2.9%) and the other 34 (97.1%) were in the control. Group. Pregnant women with pre-eclampsia had lower odds of HIV infection (odds ratio [OR] 0.10, 95% confidence interval [CI] 0.06-0.19: adjusted AOR 0.07, 95% CI 0.04-0.13, P < 0.001). Similarly, pregnant women with pre-eclampsia had lower odds of having malaria infection (OR 0.02, 95% CI 0.00-0.17, P = 0.025; adjusted OR 0.00, 95% CI 0.00-0.01, P < 0.001). CONCLUSIONS: Women with pre-eclampsia had lower odds of HIV and malaria infection in pregnancy.

A qualitative assessment of the health systems factors influencing the prevention of malaria in pregnancy using intermittent preventive treatment and insecticide-treated nets in Ghana.

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.

Reactogenicity to COVID-19 vaccination in the United States of America.

PURPOSE: In the United States, Pfizer-BioNTech, Moderna, and Janssen's coronavirus disease 2019 (COVID-19) vaccines have been granted Emergency Use Authorization (EUA) with the Pfizer-BioNTech vaccine presently approved by the US Food and Drug Administration. The purpose of this study is to analyze passive surveillance data on COVID-19 vaccine adverse reaction in the United States. MATERIALS AND METHODS: We analyzed passive surveillance data on COVID-19 vaccine adverse reactions which were retrieved from the Vaccine Adverse Event Reporting System database. Retrieved records on demographic information as well as the top 10 common vaccine adverse events were extracted and assessed from 200 of the most recently reported cases for the study analysis. RESULTS: Local and systemic adverse reactions were reported in the study. A significant difference (p<0.05) was recorded for the top 10 systemic reactions by age category (0.041) and by gender (0.002). Analysis of the top five systemic reactions, stratified by vaccine type yielded a significant difference (p<0.05) for chills (p=0.044), and when stratified by age group and type of vaccination received, it yielded a significant difference (p<0.05) for fatigue (p=0.023). Overall, Pfizer had 182 persons (91.0%) reporting adverse events, Moderna with 13 (6.5%), and Janssen with 5 (2.5%). CONCLUSION: Mild side effects were reported following vaccination with the EUA COVID-19 vaccines in the United States. Thus, continuous monitoring and reporting of all adverse events are recommended to ensure the safety of vaccination.

Evaluating the impact of COVID-19 pandemic on complicated malaria admissions and outcomes in the paediatric Ho Teaching Hospital of the Volta Region of Ghana.

Since Ghana recorded its first cases of COVID-19 in early March 2020, healthcare delivery in the country has been hugely affected by the pandemic. Malaria continues to be an important public health problem in terms of morbidity and mortality among children, and it is responsible for significant hospital visits and admission. It is likely that, as with other illnesses, the COVID-19 pandemic may have impacted health seeking behaviour, hospital visits, and admissions of malaria among the paediatric population in Ghana. The aim of this study was to evaluate the impact of COVID-19 pandemic on the admissions and outcome of complicated malaria in the Ho Teaching Hospital of the Volta Region of Ghana. The medical records of children admitted for complicated malaria (cerebral and severe malaria) from 2016 to 2020, were obtained from the admission records of the children. Both demographics and clinical details were collected, and data was analysed using SPSS version 25 statistical software. The yearly differences in the trend and proportions of complicated malaria admissions were performed using rate comparison analysis and Pearson chi-square was used to assess the association between the various demographic factors and yearly admission rates. Clopper-Pearson test statistic was employed to determine the 95% confidence intervals of outcome variables of interest. The year 2020 had the lowest admission for complicated malaria (149, 11.5%; 95% CI: 9.7-13.5) but proportionally had, more cases of cerebral malaria (25, 16.8%; 95% CI: 10.9-24.8), and more deaths (6, 4.0%; 95% CI: 1.5-8.8), compared to the years under review. Children admitted in 2020 had the shortest mean stay on admission (4.34 ±2.48, p<0.001). More studies are needed to further elucidate the impact of the COVID-19 pandemic on the health of children in malaria endemic areas.

Assessing health-seeking behaviour and malaria prevention practices among communities in four districts of the Volta Region of Ghana.

BACKGROUND: Malaria is a preventable disease that causes huge morbidity and mortality in malaria-endemic areas, especially among children and pregnant women. The malaria control programme focuses on the prevention of mosquito bites using insecticide-treated nets (ITNs) and mosquito aerosol sprays and coils, as well as prevention of severe disease among those infected through prompt and adequate treatment. The success of the malaria control programme in Ghana is dependent on the malaria prevention practices of people in the community. Therefore, this study evaluated the malaria prevention practices of participants in four districts of the Volta Region of Ghana. METHODS: This was a cross-sectional study conducted in Ketu South, Nkwanta South, Hohoe Municipality and Ho West districts of the Volta Region of Ghana. Questionnaire were administered to adults who consented to each household visited. Questions were asked on the socio-demographics and malaria prevention practices of the households. Data analysis was done using SPSS version 23 with frequency distribution done for all the variables. Pearson chi-square was used to determine the significant association between socio-demographics and malaria prevention practices, and Multivariate nominal logistic regression analysis was used to model the relationship between dichotomous dependent variables (ITN ownership and usage) and independent variables. RESULTS: Out of the 2493 participants; 2234 (89.6%) owned ITN and 1528 (68.4%) used ITN a night before this study, 768 (30.8%) used mosquito aerosol spray and 368 (15%) used mosquito coil. More females significantly owned ITN than males (1293, 92.4%, p ≤ 0.001). Participants from Ketu South had 1.5 times higher odds of owning an ITN compared to Ho West whose odds are not different from Nkwanta South or Hohoe (AOR, 1.56 [95% 1.09-2.22]; p = 0.01). In terms of ITN usage, participants in Nkwanta South were less likely to use ITN compared to the other districts; AOR, 0.434 [95% CI 0.31-0.62, p < 0.001]. Also, of the 668 participants that had a fever within the past 3 days, 268 (40.1%) visited a patent medicine store and 156 (23.4%) visited health facilities. CONCLUSION: There is high ownership of ITNs, but relatively low utilization among the community members. Education on malaria prevention practices should be intensified and continuous among the population of the Volta Region to ensure the success of malaria control in the region.

Assessing health system factors affecting access and delivery of IPTp-SP and ITN to pregnant women attending ANC clinics in Ghana.

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.

Physician Perception and Diagnosis of Intestinal Parasitic Infections among Patients with Gastrointestinal Symptoms in Ghana.

This study evaluated physicians' perception and diagnosis of intestinal parasitic infections (IPI) in patients with gastrointestinal (GI) symptoms. This cross-sectional survey used a Google form questionnaire distributed online. Demographic and clinical practice information was solicited, including if "IPI was considered as a diagnosis in the last patient seen," "if stool investigation was requested among the last patients seen," and physicians' perception of the burden of IPI in the country. Using Pearson chi-square and multivariate logistic regression analysis, we tested the significance of the associations of the job cadre of the physicians and their perception of the IPI burden with consideration of IPI as a diagnosis in the last patient seen, request for stool investigation in the last patient seen, and overall frequency of the request for stool investigation. Ultimately, 184 physicians responded. The majority agreed to "often seeing patients with GI symptoms" (156, 84.7%), "not considering IPI among the last patient seen" (106, 57.6%), and "not requesting stool investigation among the last patient seen with symptoms" (136, 73.9%). House officers (81, 44.2%) constituted the highest proportion of physicians who considered IPI as a diagnosis among the last patient seen (39, 48.1%, p = 0.05). Most physicians (138, 75%) considered IPI as a burden in Ghana. They constituted significant proportions of the physicians who considered IPI as a diagnosis among their last patients seen (65, 83.3%, p = 0.02) and were twice more likely to consider IPI as a diagnosis among the last patients seen than their colleagues who did not consider IPI as a burden in Ghana (AOR 2.26, p = 0.04). The consideration of IPI as a diagnosis among patients with GI symptoms and request for stool investigations was low among physicians in this study. Further engagements with physicians in Ghana are needed to help improve their diagnosis of IPI in patients with GI symptoms.

Is malaria immunity a possible protection against severe symptoms and outcomes of COVID-19?

Malaria-endemic areas of the world are noted for high morbidity and mortality from malaria. Also noted in these areas is the majority of persons in the population having acquired malaria immunity. Though this acquired malaria immunity does not prevent infection, it resists the multiplication of Plasmodium parasites, restricting disease to merely uncomplicated cases or asymptomatic infections. Does this acquired malaria immunity in endemic areas protect against other diseases, especially outbreak diseases like COVID-19? Does malaria activation of innate immunity resulting in trained or tolerance immunity contribute to protection against COVID-19? In an attempt to answer these questions, this review highlights the components of malaria and viral immunity and explores possible links with immunity against COVID-19. With malaria-endemic areas of the world having a fair share of cases of COVID-19, it is important to direct research in this area to evaluate and harness any benefits of acquired malaria immunity to help mitigate the effects of COVID-19 and any possible future outbreaks. FUNDING: None declared.

The Epidemiology of Bloodstream Infections and Antimicrobial Susceptibility Patterns: A Nine-Year Retrospective Study at St. Dominic Hospital, Akwatia, Ghana.

BACKGROUND: Bloodstream infections are among the top causes of morbidity and mortality in people of all ages, especially in immunocompromised patients in sub-Saharan Africa. This study aimed at describing the epidemiology of bloodstream infections and antimicrobial susceptibility pattern over a nine-year period at St. Dominic Hospital, Akwatia, in the Eastern Region of Ghana. METHOD: This study retrospectively analysed data from 4,489 patients who were referred to the Laboratory Department for blood culture and sensitivity testing from January 2009 to December 2017. Sociodemographic data included age, gender, and patients' department. Blood culture results were retrieved from archival records in the laboratory. The authorities of St. Dominic Hospital granted approval for the study. RESULTS: The incidence of bloodstream infection over the 9 years was 51.4 positive cultures per 100,000 hospital attendance. Staphylococcus aureus was the leading causative agent of bacteraemia for the first two scalar years (2009-2011 (38.9%) and 2012-2014 (42.2%)) while coagulase-negative staphylococcus (CoNS) (50.5%) was predominant for the last scalar year (2015-2017), followed by Staphylococcus aureus (169/587 (28.8%)). The highest incidence of bloodstream infections was recorded in the wet seasons (months of May (8.9 per 10,000 persons) and October (10.1 per 10,000 persons)). The bacterial isolates demonstrated high resistance to tetracyclines (390/531 (73.4%)), penicillins (1282/1669 (76.8%)), and sulphonamides (450/499 (90.2%)). CONCLUSION: Bloodstream infection and antimicrobial resistance are high in patients seeking healthcare in Akwatia. This therefore calls for concerted efforts aimed at reducing the incidence in the study area.

Socioeconomic Risk Factors for Plasmodium falciparum Infection in Primary School Children in Three Districts of the Volta Region Of Ghana.

BACKGROUND: Socioeconomic factors influence the prevalence of malaria infection in endemic areas. This study evaluated the socioeconomic risk factors for Plasmodium falciparum infection in primary school children in the Volta region of Ghana. METHODS: This cross-sectional study involved selected primary school children from the region; questionnaires were administered, and blood samples were collected for malaria detection using a rapid diagnostic test (RDT) and microscopy. RESULTS: A total of 550 primary school children were enrolled in this study. The predominant occupation of the parents was trading (mothers, 334, 60.73%; fathers, 254, 46.18%) and farming (mothers, 156, 28.36%; fathers, 170, 30.91%). Three hundred and five (305; 55.45%) children tested positive for malaria with RDT and microscopy. Male sex (AOR=1.53), rural area (Afegame school) (AOR=4.01) and parental farming occupation (AOR=6.39), were independently associated with P. falciparum infection. CONCLUSIONS: Plasmodium falciparum infection was significantly found in children in rural areas of Ghana with low socioeconomic status in this study.

Prevalence of Polyparasitic Infection Among Primary School Children in the Volta Region of Ghana.

BACKGROUND: Polyparasitic infection is a possibility in areas where parasites are endemic, especially among children. This study looked at the prevalence of polyparasitic infections among children in the Volta Region of Ghana. METHODS: This was a cross-sectional study, among 550 primary school children (aged 6-14 years) in 3 districts in the Volta Region. Questionnaires were administered, and blood, stool, and urine samples were collected. Blood samples were screened for Plasmodium falciparum with rapid diagnostic test and microscopy, together with hemoglobin estimation. Stool and urine samples were microscopically examined using wet mount and sedimentation methods to detect intestinal parasites and Schistosoma haematobium, respectively. Pearson χ2 test was used to evaluate the association between parasitic infections and socioeconomic variables, and multivariate logistic regression to evaluate paired associations among parasites. RESULTS: The most prominent infection among the children was P. falciparum (present in 383 children [69.6%]), followed by S. haematobium (57 [10.36%]). There was low prevalence of intestinal protozoa (present in 11 children [2%]), Ascaris lumbricoides (7 [1.27%]), and hookworm (5 [0.91%]). A total of 62 children had polyparasitic infection, with P. falciparum and S. haematobium having significant paired association (both present in 46 children [74.19%]; adjusted odds ratio, 2.45; P = .007). CONCLUSION: The prevalence of polyparasitic infection was low in this study, and significant coinfection was seen with P. falciparum and S. haematobium.
