Prevalence and predictors of low folate levels among stroke survivors in a country without mandatory folate food fortification: Analysis of a Ghanaian sample.

BACKGROUND: While additional folic acid (FA) treatment has a neutral effect on lowering overall vascular risk in countries that mandate FA fortification of food, meta-analytic data suggest that folate supplementation reduces stroke risk in certain patient subgroups, and among people living in countries without mandatory folate food fortification. However, the burden of folate deficiency among adults with stroke in the world's poorest continent is unknown. PURPOSE: To assess the prevalence and predictors of folate deficiency among recent ischemic stroke survivors. METHODS: We analyzed data among consecutively encountered ischemic stroke patients aged ≥18 years at a tertiary medical center in Kumasi, Ghana between 10/2020 - 08/2021. We identified a modest sample of stroke free adults to serve as a comparator group. Fasting serum folate was measured using a radioimmunoassay and a cut-off of 4ng/mL used to define folate deficiency. Factors associated with serum folate concentration were assessed using a multilinear regression model. RESULTS: Comparing stroke cases (n = 116) with stroke-free comparators (n = 20), mean folate concentration was lower among stroke cases (7 ng/ml vs. 10.2 ng/ml, p = 0.004). Frequency of folate deficiency was higher among stroke cases vs. stroke-free controls (31% vs 5%, p = 0.02). Male sex (beta coefficient of -2.6 (95% CI: -4.2, -0.9) and LDL (ß: -0.76; -1.4, -0.07) were significantly associated with serum folate concentration. CONCLUSION: Almost one in three ischemic stroke survivors have folate deficiency potentially accentuating their risk for further adverse atherosclerotic events in a setting without folate fortification. A clinical trial of folate supplementation among stroke survivors is warranted.

Accuracy of Weight Estimation in Children Using the Broselow, PAWPER XL, PAWPER XL-MAC, and Mercy Tapes.

OBJECTIVES: Quick and accurate estimate of a child's weight is often required for medical interventions like drug dose calculation when scale measured weights cannot be obtained safely. Length-based methods of weight estimation are more accurate than age-based methods, with the most accurate being the length-based, habitus-modified methods. This study sought to determine and compare the accuracies of the 2017 Broselow tape, Paediatric Advanced Weight Prediction in the Emergency Room Extra-Long (PAWPER XL) tape, Paediatric Advanced Weight Prediction in the Emergency Room Extra-Long Mid-Arm Circumference (PAWPER XL-MAC) tape, and the 2-dimensional (2D) Mercy tape in Ghanaian children. METHODS: A cross-sectional study was conducted at the Tamale Teaching Hospital in Ghana. Eight hundred forty children between 2 months and 13 years had their weights estimated by the 2017 Broselow, PAWPER XL, PAWPER XL-MAC, and 2D Mercy tapes. Accuracy of the methods was determined by percentage of weight estimated to within 10% and 20% of actual weight. Mean percentage error and the Bland-Altman analysis were used to assess bias and precision. RESULTS: The proportion of weight estimates within 10% and 20% of actual weight for Broselow tape were 47.5% and 82.3%, for 2D Mercy tape were 73.1% and 96.3%, for PAWPER XL-MAC were 77.6% and 97.5%, and for PAWPER XL were 81.7% and 96.8%, respectively. The Broselow tape had the greatest bias and least precision among the 4 methods. The Mercy, PAWPER XL-MAC, and PAWPER XL tapes had similar performance, but all performed significantly better than the Broselow tape in pairwise comparison. The best weight estimation method overall was the PAWPER XL tape as it also had the least bias and greatest precision. CONCLUSIONS: The Mercy, PAWPER XL-MAC, and PAWPER XL tapes were more accurate than the 2017 Broselow tape and should be used in preference in Ghana and countries with similar population structure.

Timing of initiation of breastfeeding and its determinants at a tertiary hospital in Ghana: a cross-sectional study.

BACKGROUND: Early initiation of breastfeeding (EIBF), breastfeeding within first hour after birth, is known to have major benefits for both the mother and newborn. EIBF rates, however, tends to vary between and within countries. This study set out to determine the prevalence of EIBF at the Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana, and to evaluate the determinants of EIBF and time to initiation of breastfeeding. METHODS: A cross-sectional study was conducted at the KATH postnatal wards between August and October 2014. Three hundred and eighty-two mothers delivering at KATH were recruited and data on time to initiation of breastfeeding, antenatal, delivery and immediate postnatal periods were collected. Data analyses using both binary and ordinal logistic regressions with stepwise elimination were used to determine the relationship between EIBF and time to initiation of breastfeeding on one side, and the maternal, pregnancy, delivery and neonatal associated factors. RESULTS: EIBF was done in 39.4% (95%CI: 34.3-44.5) of the newborns with breastfeeding initiated between 1 to 6 h for 19.7%, 6 to 11 h in 4.8%, 11 to 16 h in 4.8% and after 16 h in 28.5% of the deliveries. A higher number of antenatal care visits (AOR = 1.14, 95%CI: 1.04-1.25, p = 0.006), delivery by caesarean section (AOR = 0.07, 95%CI: 0.01-0.79, p = 0.031) and infant rooming-in with mother (AOR: 31.67, 95%CI: 5.59-179.43, p <  0.001) were significantly and independently associated with EIBF. Factors independently associated with longer time to initiation of breastfeeding were older maternal age (AOR = 1.04, 95%CI: 1.00-1.09, p = 0.039), Akan ethnicity (AOR = 1.92, 95%CI: 1.14-3.22, p = 0.014), first-born child (AOR = 2.06, 95%CI: 1.18-3.58, p = 0.011), mother rooming-in with newborn (AOR = 0.01. 95%CI: 0.00-0.02, p <  0.001), increasing fifth minute APGAR score (AOR = 0.73, 95%CI: 0.58-0.93, p = 0.010) and using prelacteals (AOR = 2.42, 95%CI: 1.34-4.40, p = 0.004). CONCLUSIONS: The low EIBF rate and prolonged time to initiation of breastfeeding at a major tertiary health facility is a major concern. Key interventions will need to be implemented at KATH and possibly other tertiary healthcare facilities in Ghana and beyond to improve EIBF rate and time to breastfeeding.

Decreased Mortality After Establishing a Pediatric Emergency Unit at an Urban Referral Hospital in Ghana.

ABSTRACT: Emergently ill infants and children are often inadequately recognized and stabilized by health care facilities in low- and middle-income countries. Limited reports have shown that process improvements and prioritization of emergency care for children presenting to the hospital can improve pediatric hospital mortality.A dedicated pediatric emergency unit (PEU) was established for nontrauma emergencies at a busy teaching and referral hospital in Kumasi, Ghana, in response to high inpatient mortality early during hospitalization. The PEU was designed to identify and separate critically ill children from more stable children on admission. Locally available hospital resources were reallocated from other areas of the hospital to prioritize staffing and supplies for the PEU.A multiyear data set of nonnewborn inpatient mortality was analyzed with a change point model to find the point at which mortality changed the most within the Department of Child Health or the maximum likelihood estimate. Relative risk of mortality for the periods 1 and 2 years immediately before and after the implementation of the PEU and each individual year compared with its preceding year was analyzed to further establish a temporal correlation of changes in mortality rates to the PEU implementation. Individual years were also analyzed against preimplementation data to establish the durability of mortality improvements.Patient mortality decreased over the analyzed period with the maximum change point strongly associated with implementation of the PEU. Relative risk values of mortality 1 year and 2 years immediately before and after implementation of the PEU were 0.70 (0.62-0.78) and 0.69 (0.64-0.74) respectively, representing a one-third reduction in mortality. The only other mortality improvements seen in the year-to-year analysis were between July 2004-June 2005 compared with July 2005-June 2006 with a relative risk of 0.86 (0.77-0.96).Prioritizing and redirecting limited resources toward pediatric emergency care in low- and middle-income country hospitals is associated with reductions in inpatient mortality that are both immediate and sustained.

Phone-Based Intervention under Nurse Guidance after Stroke (PINGS II) Study: Protocol for a Phase III Randomized Clinical Trial.

OBJECTIVES: The Sub-Saharan African (SSA) region now has the highest estimated effect size of hypertension for stroke causation worldwide. An urgent priority for countries in SSA is to develop and test self-management interventions to control hypertension among those at highest risk of adverse outcomes. Thus the overall objective of the Phone-based Intervention under Nurse Guidance after Stroke II study (PINGS-2) is to deploy a hybrid study design to assess the efficacy of a theoretical-model-based, mHealth technology-centered, nurse-led, multi-level integrated approach to improve longer term blood pressure (BP) control among stroke survivors. MATERIALS AND METHODS: A phase III randomized controlled trial involving 500 recent stroke survivors to be enrolled across 10 Ghanaian hospitals. Using a computer-generated sequence, patients will be randomly assigned 1:1 into the intervention or usual care arms. The intervention comprises of (i) home BP monitoring at least once weekly with nurse navigation for high domiciliary BP readings; (2) medication reminders using mobile phone alerts and (3) education on hypertension and stroke delivered once weekly via audio messages in preferred local dialects. The intervention will last for 12 months. The control group will receive usual care as determined by local guidelines. The primary outcome is the proportion of patients with systolic BP <140 mm Hg at 12 months. Secondary outcomes will include medication adherence, self-management of hypertension, major adverse cardiovascular events, health related quality of life and implementation outcomes. CONCLUSION: An effective PINGS intervention can potentially be scaled up and disseminated across healthcare systems in low-and-middle income countries challenged with resource constraints to reduce poor outcomes among stroke survivors.

Genome-wide association study indicates two novel resistance loci for severe malaria.

Malaria causes approximately one million fatalities per year, mostly among African children. Although highlighted by the strong protective effect of the sickle-cell trait, the full impact of human genetics on resistance to the disease remains largely unexplored. Genome-wide association (GWA) studies are designed to unravel relevant genetic variants comprehensively; however, in malaria, as in other infectious diseases, these studies have been only partly successful. Here we identify two previously unknown loci associated with severe falciparum malaria in patients and controls from Ghana, West Africa. We applied the GWA approach to the diverse clinical syndromes of severe falciparum malaria, thereby targeting human genetic variants influencing any step in the complex pathogenesis of the disease. One of the loci was identified on chromosome 1q32 within the ATP2B4 gene, which encodes the main calcium pump of erythrocytes, the host cells of the pathogenic stage of malaria parasites. The second was indicated by an intergenic single nucleotide polymorphism on chromosome 16q22.2, possibly linked to a neighbouring gene encoding the tight-junction protein MARVELD3. The protein is expressed on endothelial cells and might therefore have a role in microvascular damage caused by endothelial adherence of parasitized erythrocytes. We also confirmed previous reports on protective effects of the sickle-cell trait and blood group O. Our findings underline the potential of the GWA approach to provide candidates for the development of control measures against infectious diseases in humans.

Availability and price of malaria rapid diagnostic tests in the public and private health sectors in 2011: results from 10 nationally representative cross-sectional retail surveys.

OBJECTIVES: To describe the state of the public and private malaria diagnostics market shortly after WHO updated its guidelines for testing all suspected malaria cases prior to treatment. METHODS: Ten nationally representative cross-sectional cluster surveys were conducted in 2011 among public and private health facilities, community health workers and retail outlets (pharmacies and drug shops) in nine countries (Tanzania mainland and Zanzibar surveyed separately). Eligible outlets had antimalarials in stock on the day of interview or had stocked antimalarials in the past 3 months. RESULTS: Three thousand four hundred and thirty-nine rapid diagnostic test (RDT) products from 39 manufacturers were audited among 12,197 outlets interviewed. Availability was typically highest in public health facilities, although availability in these facilities varied greatly across countries, from 15% in Nigeria to >90% in Madagascar and Cambodia. Private for-profit sector availability was 46% in Cambodia, 20% in Zambia, but low in other countries. Median retail prices for RDTs in the private for-profit sector ranged from $0.00 in Madagascar to $3.13 in Zambia. The reported number of RDTs used in the 7 days before the survey in public health facilities ranged from 3 (Benin) to 50 (Zambia). CONCLUSIONS: Eighteen months after WHO updated its case management guidelines, RDT availability remained poor in the private sector in sub-Saharan Africa. Given the ongoing importance of the private sector as a source of fever treatment, the goal of universal diagnosis will not be achievable under current circumstances. These results constitute national baselines against which progress in scaling-up diagnostic tests can be assessed.

Impact of socioeconomic status and medical conditions on health and healthcare utilization among aging Ghanaians.

BACKGROUND: This study attempts to examine the impact of socioeconomic and medical conditions in health and healthcare utilization among older adults in Ghana. Five separate models with varying input variables were estimated for each response variable. METHODS: Data (Wave 1 data) were drawn from the World Health Organization Global Ageing and Adult Health (SAGE) conducted during 2007-2008 and included a total of 4770 respondents aged 50+ and 803 aged 18-49 in Ghana. Ordered logits was estimated for self-rated health, and binary logits for functional limitation and healthcare utilization. RESULTS: Our results show that the study provides enough grounds for further research on the interplay between socioeconomic and medical conditions on one hand and the health of the aged on the other. Controlling for socioeconomic status substantially contributes significantly to utilization. Also, aged women experience worse health than men, as shown by functioning assessment, self-rated health, chronic conditions and functional limitations. Women have higher rates of healthcare utilization, as shown by significantly higher rates of hospitalization and outpatient encounters. CONCLUSION: Expansion of the national health insurance scheme to cover the entire older population--for those in both formal and informal employments--is likely to garner increased access and improved health states for the older population.

Communicating the AMFm message: exploring the effect of communication and training interventions on private for-profit provider awareness and knowledge related to a multi-country anti-malarial subsidy intervention.

BACKGROUND: The Affordable Medicines Facility - malaria (AMFm), implemented at national scale in eight African countries or territories, subsidized quality-assured artemisinin combination therapy (ACT) and included communication campaigns to support implementation and promote appropriate anti-malarial use. This paper reports private for-profit provider awareness of key features of the AMFm programme, and changes in provider knowledge of appropriate malaria treatment. METHODS: This study had a non-experimental design based on nationally representative surveys of outlets stocking anti-malarials before (2009/10) and after (2011) the AMFm roll-out. RESULTS: Based on data from over 19,500 outlets, results show that in four of eight settings, where communication campaigns were implemented for 5-9 months, 76%-94% awareness of the AMFm 'green leaf' logo, 57%-74% awareness of the ACT subsidy programme, and 52%-80% awareness of the correct recommended retail price (RRP) of subsidized ACT were recorded. However, in the remaining four settings where communication campaigns were implemented for three months or less, levels were substantially lower. In six of eight settings, increases of at least 10 percentage points in private for-profit providers' knowledge of the correct first-line treatment for uncomplicated malaria were seen; and in three of these the levels of knowledge achieved at endline were over 80%. CONCLUSIONS: The results support the interpretation that, in addition to the availability of subsidized ACT, the intensity of communication campaigns may have contributed to the reported levels of AMFm-related awareness and knowledge among private for-profit providers. Future subsidy programmes for anti-malarials or other treatments should similarly include communication activities.

Mental health related determinants of parenting stress among urban mothers of young children--results from a birth-cohort study in Ghana and Côte d'Ivoire.

BACKGROUND: There are limited data on the parenting stress (PS) levels in sub-Saharan African mothers and on the association between ante- and postnatal depression and anxiety on PS. METHODS: A longitudinal birth cohort of 577 women from Ghana and Côte d'Ivoire was followed from the 3rd trimester in pregnancy to 2 years postpartum between 2010 and 2013. Depression and anxiety were assessed by the Patient Health Questionnaire depression module (PHQ-9) and the Generalized Anxiety Disorder (GAD-7) at baseline, 3 month, 12 month and 24 month postpartum. PS was measured using the Parenting Stress Index-Short Form (PSI-SF) at 3, 12 and 24 month. The mean total PS score and the subscale scores were compared among depressed vs. non-depressed and among anxious vs. non-anxious mothers at 3, 12 and 24 month postpartum. The proportions of clinical PS (PSI-SF raw score > 90) in depressed vs. non-depressed and anxious vs. non-anxious mothers were also compared. A generalized estimating equation (GEE) approach was used to estimate population-averaged associations between women's depression/anxiety and PS adjusting for age, child sex, women's anemia, education, occupation, spouse's education, and number of sick child visits. RESULTS: A total of 577, 531 and 264 women completed the PS assessment at 3 month, 12 month and 24 month postpartum across the two sites and the prevalences of clinical PS at each time point was 33.1%, 24.4% and 14.9% in Ghana and 30.2%, 33.5% and 22.6% in Côte d'Ivoire, respectively. At all three time points, the PS scores were significantly higher among depressed mothers vs. non-depressed mothers. In the multivariate regression analyses, antepartum and postpartum depression were consistently associated with PS after adjusting for other variables. CONCLUSIONS: Parenting stress is frequent and levels are high compared with previous studies from high-income countries. Antepartum and postpartum depression were both associated with PS, while antepartum and postpartum anxiety were not after adjusting for confounders. More quantitative and qualitative data are needed in sub-Saharan African populations to assess the burden of PS and understand associated mechanisms. Should our findings be replicated, it appears prudent to design and subsequently evaluate intervention strategies.

Ethical aspects of arranging local medical collaboration and care.

Yearly pediatric cardiac surgery missions to Ghana are of tremendous benefit to local children, but may create thorny ethical dilemmas for local clinicians who refer and screen children for the mission and who provide care to the children after the mission concludes for the year. This article presents the experiences and concerns of a pediatrician who is a local member of the Hearts and Minds of Ghana project.

Atherosclerotic cardiovascular disease risk among Ghanaians: A comparison of the risk assessment tools.

Objectives: Risk stratification is a cornerstone for preventing atherosclerotic cardiovascular disease (ASCVD). Ghana has yet to develop a locally derived and validated ASCVD risk model. A critical first step towards this goal is assessing how the commonly available risk models perform in the Ghanaian population. This study compares the agreement and correlation between four ASCVD risk assessment models commonly used in Ghana. Methods: The Ghana Heart Study collected data from four regions in Ghana (Ashanti, Greater Accra, Northern, and Central regions) and excluded people with a self-declared history of ASCVD. The 10-year fatal/non-fatal ASCVD risk of participants aged 40-74 was calculated using mobile-based apps for Pooled Cohort Equation (PCE), laboratory-based WHO/ISH CVD risk, laboratory-based Framingham risk (FRS), and Globorisk, categorizing them as low, intermediate, or high risk. The risk categories were compared using the Kappa statistic and Spearman correlation. Results: A total of 615 participants were included in this analysis (median age 55 [Inter quartile range 46, 64]) years with 365 (59.3 %) females. The WHO/ISH risk score categorized 504 (82.0 %), 58 (9.4 %), and 53 (8.6 %) as low-, intermediate-, and high-risk, respectively. The PCE categorized 345 (56.1 %), 181 (29.4 %), and 89 (14.5 %) as low-, intermediate- and high-risk, respectively. The Globorisk categorized 236 (38.4 %), 273 (44.4 %), and 106 (17.2 %) as low-, intermediate-, and high-risk, respectively. Significant differences in the risk categorization by region of residence and age group were noted. There was substantial agreement between the PCE vs FRS (Kappa = 0.8, 95 % CI 0.7 - 0.8), PCE vs Globorisk (Kappa = 0.6; 95 % CI 0.6 - 0.7), and FRS vs Globorisk (Kappa = 0.6; 95 % CI 0.6 - 0.7). However, there was only fair agreement between the WHO vs Globorisk (Kappa = 0.3; 95 % CI 0.3-0.4) and moderate agreement between the WHO vs PCE and WHO vs FRS. Conclusion: There are significant differences in the ASCVD risk prediction tools in the Ghanaian population, posing a threat to primary prevention. Therefore, there is a need for locally derived and validated tools.

Aetiological agents of pneumonia among HIV and non-HIV infected children in Ghana: A case-control study.

Pneumonia is the leading cause of death in children, however, the microbial aetiology of pneumonia is not well elucidated in low- and middle-income countries. Our study was aimed at determining the microbial aetiologies of childhood pneumonia and associated risk factors in HIV and non-HIV infected children. We conducted a case-control study that enrolled children with pneumonia as cases and non-pneumonia as controls from July 2017 to May 2020. Induced sputum and blood samples were investigated for microbial organisms using standard microbiological techniques. DNA/RNA was extracted from sputum samples and tested for viral and bacterial agents. Four hundred and four (404) subjects consisting of 231 (57.2%) cases and 173 (42.8%) controls were enrolled. We identified a significant (p = 0.011) proportion of viruses in cases (125; 54.1%, 95%CI: 47.4-60.7) than controls (71; 33.6%, 95%CI: 33.6-48.8) and these were mostly contributed to by Respiratory Syncytial Virus. Staphylococcus aureus (16; 4.0%), Klebsiella spp. (15, 3.7%) and Streptococcus pneumoniae (8, 2.0%) were the main bacterial agents identified in sputum or induced sputum samples. HIV infected children with viral-bacterial co-detection were found to have very severe pneumonia compared to those with only viral or bacterial infection. Indoor cooking (OR = 2.36; 95%CI:1.41-3.96) was found to be associated with pneumonia risk in patients. This study demonstrates the importance of various microbial pathogens, particularly RSV, in contributing to pneumonia in HIV and non-HIV paediatric populations. There is a need to accelerate clinical trials of RSV vaccines in African populations to support improvement of patient care.

HIV infection in severely malnourished children in Kumasi, Ghana: a cross-sectional prospective study.

BACKGROUND: The Human Immunodeficiency Virus (HIV) epidemic has adversely affected the nutritional status and mortality of children in Africa. This study assessed the disease burden, predictive clinical features and outcomes for children with severe acute malnutrition (SAM) and concomitant HIV infection. METHODS: This was a cross-sectional prospective study of children with SAM aged between 3 months and 13 years admitted to the nutritional rehabilitation unit (NRU) of Komfo Anokye Teaching Hospital. Socio-demographic, anthropometric and clinical data were documented and HIV serostatus established with 2 rapid HIV antibody tests and Enzyme-linked immunosorbent assay, if indicated. HIV viral polymerase chain reaction testing was not available at the time of the study. Logistic regression analyses were used to identify significant clinical predictors of HIV seropositivity. RESULTS: Sixty-seven (27.2%, 95% CI = 21.8-33.3%) of the 246 study children had positive HIV antibody results. Uptake of provider-initiated HIV testing and counselling was 100%. Amongst children aged 18 months and over, the HIV seroprevalence was 28.3% (30/106). HIV seropositivity was strongly associated with prolonged fever, cough and diarrhoea; oral thrush, generalised lymphadenopathy and pulmonary tuberculosis (p value < 0.001 for all parameters). The presence of ≥ 3 of the first 5 aforementioned parameters was highly specific (98.3-100%) for HIV seropositivity in study children. HIV seropositivity was also significantly associated with cough, vomiting, lethargy/altered consciousness, skin rash and hepatomegaly (p value < 0.05 for all parameters). Overall mortality rate was 17.5%, with HIV seropositive children having a significantly higher mortality rate (37.8% versus 10.1%; p value < 0.001) and a lower rate of weight gain (2.4 g/kg/day versus 7.0 g/kg/day; p value < 0.001). CONCLUSIONS: HIV testing was well accepted by parents/carers and should be offered in all NRUs. There was a high HIV seroprevalence among children with SAM and a significantly poorer outcome in mortality and weight gain. Some clinical features were identified to be predictive of HIV seropositivity and could be useful as indicators to prompt further investigation and/or referral in resource limited settings where HIV test kits are unavailable. This would aid in the early detection and comprehensive management of the HIV seropositive child with SAM.

Weight estimation in two groups of Ghanaian children with chronic diseases using Broselow, Mercy, PAWPER XL and PAWPER XL-MAC tapes.

Introduction: The performance of various weight estimation methods in children with sickle cell disease (SCD) and heart disease (HD) has not been studied. We aimed to determine and compare the accuracies of the Broselow, Mercy, PAWPER XL and PAWPER XL-MAC tapes in Ghanaian children with no known chronic diseases (controls), SCD and HD. Methods: We prospectively recruited 631 children (199 with HD, 209 SCD and 223 controls) from the Komfo Anokye Teaching Hospital (KATH). Their weights were estimated using the Broselow, Mercy, PAWPER XL and PAWPER XL-MAC tapes. These estimated weights were compared to measured weight using mean percentage error (MPE), the proportion of weight estimates within ±10% (P10) and ±20% (P20) of measured weight. Bland-Altman limits of agreement (LOA) were determined to assess the precision of weight estimation and agreement with measured weight. Results: The PAWPER XL, Mercy and PAWPER XL-MAC were the most accurate in all groups of children studied. All methods except the Broselow tape (BT), which performed best in the control group, had their best performance among children with SCD with negligible critical error rates (proportion of children with weight estimates > 20% of their actual weight). The P20 in the various groups of children using the BT were 88.36%, 80.21% and 51.10% respectively in the control, SCD and HD groups. The Mercy, PAWPER XL and PAWPER XL MAC tapes were generally above 90% in all groups. Discussion: The Mercy, PAWPER XL and PAWPER XL-MAC tapes performed significantly better than the BT in all groups of children studied. These methods of weight estimation performed best in children with SCD with very little critical error.

Hospitalizations among children with sickle cell disease enrolled in the Kumasi Sickle Cell Pan African Consortium (SPARCo) database: A cross sectional study.

Background and Aims: Sickle cell disease (SCD) is the commonest monogenic haemolytic disorder in Africa. Despite strides made in its management, a significant proportion of patients are hospitalized from the various complications of the disease. This study set out to describe the main causes and outcomes of hospitalizations among pediatric patients with SCD. Methods: A cross-sectional study was conducted at the Pediatric Emergency Unit of Komfo Anokye Teaching Hospital within a period of 12 months to recruit pediatric SCD patients. This study looked at causes of admission, length of hospital stay (LOS), and outcome of admission. Results: Of the 201 SCD patients recruited, 57.2% were males and majority were of SCD-SS phenotype 83.1%. The median age was 6 years. The three leading causes of hospitalization were Vaso-occlusive pain events (VOPE) (39.8%), acute chest syndrome (ACS) (25.9%), and infections (12.4%). Ten (5.0%) of the patients presented with a stroke. High admissions were observed in June (12.4%) and November (16.9%). The median (interquartile range [IQR]) LOS was 6 days (IQR: 4-10). Six (3.0%) of the patients died from complications of the disease during hospitalization. Conclusion: VOPE, ACS, infections, and acute anaemia from hyperhaemolysis were observed as the most common causes of admissions among SCD patients. A good outcome of discharge was seen in most of the patients that were hospitalized with a median length of stay of 6 days. This study also strengthens the importance of a good SCD database with patient follow-ups for better outcomes in SCD patients.

Screening for Resistant Bacteria, Antimicrobial Resistance Genes, Sexually Transmitted Infections and Schistosoma spp. in Tissue Samples from Predominantly Vaginally Delivered Placentae in Ivory Coast and Ghana.

Medical complications during pregnancy have been frequently reported from Western Africa with a particular importance of infectious complications. Placental tissue can either become the target of infectious agents itself, such as, e.g., in the case of urogenital schistosomiasis, or be subjected to contamination with colonizing or infection-associated microorganisms of the cervix or the vagina during vaginal delivery. In the retrospective cross-sectional assessment presented here, the quantitative dimension of infection or colonization with selected resistant or pathogenic bacteria and parasites was regionally assessed. To do so, 274 collected placental tissues from Ivory Coastal and Ghanaian women were subjected to selective growth of resistant bacteria, as well as to molecular screening for beta-lactamase genes, Schistosoma spp. and selected bacterial causative agents of sexually transmitted infections (STI). Panton-Valentine-negative methicillin-resistant Staphylococcus aureus (MRSA) was grown from 1.8% of the tissue samples, comprising the spa types t008 and t688, as well as the newly detected ones, t12101 (n = 2) and t12102. While the culture-based recovery of resistant Enterobacterales and nonfermentative rod-shaped Gram-negative bacteria failed, molecular assessments confirmed beta-lactamase genes in 31.0% of the samples with multiple detections of up to four resistance genes per sample and blaCTX-M, blaIMP, blaGES, blaVIM, blaOXA-58-like, blaNDM, blaOXA-23-like, blaOXA-48-like and blaKPC occurring in descending order of frequency. The beta-lactamase genes blaOXA-40/24-like, blaNMC_A/IMI, blaBIC, blaSME, blaGIM and blaDIM were not detected. DNA of the urogenital schistosomiasis-associated Schistosoma haematobium complex was recorded in 18.6% of the samples, but only a single positive signal for S. mansoni with a high cycle-threshold value in real-time PCR was found. Of note, higher rates of schistosomiasis were observed in Ghana (54.9% vs. 10.3% in Ivory Coast) and Cesarean section was much more frequent in schistosomiasis patients (61.9% vs. 14.8% in women without Schistosoma spp. DNA in the placenta). Nucleic acid sequences of nonlymphogranuloma-venereum-associated Chlamydia trachomatis and of Neisseria gonorrhoeae were recorded in 1.1% and 1.9% of the samples, respectively, while molecular attempts to diagnose Treponema pallidum and Mycoplasma genitalium did not lead to positive results. Molecular detection of Schistosoma spp. or STI-associated pathogens was only exceptionally associated with multiple resistance gene detections in the same sample, suggesting epidemiological distinctness. In conclusion, the assessment confirmed considerable prevalence of urogenital schistosomiasis and resistant bacterial colonization, as well as a regionally expected abundance of STI-associated pathogens. Continuous screening offers seem advisable to minimize the risks for the pregnant women and their newborns.

A cardiovascular polypill for secondary stroke prevention in a tertiary centre in Ghana (SMAART): a phase 2 randomised clinical trial.

BACKGROUND: A cardiovascular polypill containing generic drugs might facilitate sustained implementation of and adherence to evidence-based treatments, especially in resource-limited settings. However, the impact of a cardiovascular polypill in mitigating atherosclerotic risk among stroke survivors has not been assessed. We aimed to compare a polypill regimen with usual care on carotid intima-media thickness (CIMT) regression after ischaemic stroke. METHODS: In SMAART, a phase 2 parallel, open-label, assessor-masked, randomised clinical trial, we randomly allocated individuals (aged ≥18 years) who had an ischaemic stroke within the previous 2 months, using a computer-generated randomisation sequence (1:1), to either a polypill or usual care group at a tertiary centre in Ghana. The polypill regimen was a fixed-dose pill containing 5 mg ramipril, 50 mg atenolol, 12·5 mg hydrochlorothiazide, 20 mg simvastatin, and 100 mg aspirin administered as two capsules once per day for 12 months. Usual care was tailored guideline-recommended secondary prevention medications. The primary outcome was the change in CIMT over 12 months with adjustment for baseline values, compared using ANCOVA in all participants with complete data at month 12. Safety was analysed in all randomly assigned participants. This trial is registered at ClinicalTrials.gov, NCT03329599, and is completed. FINDINGS: Between Feb 12, 2019, and Dec 4, 2020, we randomly assigned 148 participants (74 to the usual care group and 74 to the polypill group), 74 (50%) of whom were male and 74 (50%) female. CIMT was assessed in 62 (84%) of 74 participants in the usual care group and 59 (80%) of 74 participants in the polypill group; the main reason for loss to follow-up was participants not completing the study. The mean CIMT change at month 12 was -0·092 mm (95% CI -0·130 to -0·051) in the usual care group versus -0·017 mm (-0·067 to 0·034) in the polypill group, with an adjusted mean difference of 0·049 (-0·008 to 0·109; p=0·11). Serious adverse events occurred among two (3%) participants in the usual care group, and eight (11%) participants in the polypill group (p=0·049). INTERPRETATION: The polypill regimen resulted in similar regression in subclinical atherosclerosis and many secondary and tertiary outcome measures as the tailored drug regimen, but with more serious adverse events. Larger, longer-term, event-based studies, including patients with stroke in primary care settings, are warranted. FUNDING: US National Institutes of Health.

Predicting the clinical outcome of severe falciparum malaria in african children: findings from a large randomized trial.

BACKGROUND: Data from the largest randomized, controlled trial for the treatment of children hospitalized with severe malaria were used to identify such predictors of a poor outcome from severe malaria. METHODS: African children (<15 years) with severe malaria participated in a randomized comparison of parenteral artesunate and parenteral quinine in 9 African countries. Detailed clinical assessment was performed on admission. Parasite densities were assessed in a reference laboratory. Predictors of death were examined using a multivariate logistic regression model. RESULTS: Twenty indicators of disease severity were assessed, out of which 5 (base deficit, impaired consciousness, convulsions, elevated blood urea, and underlying chronic illness) were associated independently with death. Tachypnea, respiratory distress, deep breathing, shock, prostration, low pH, hyperparasitemia, severe anemia, and jaundice were statistically significant indicators of death in the univariate analysis but not in the multivariate model. Age, glucose levels, axillary temperature, parasite density, heart rate, blood pressure, and blackwater fever were not related to death in univariate models. CONCLUSIONS: Acidosis, cerebral involvement, renal impairment, and chronic illness are key independent predictors for a poor outcome in African children with severe malaria. Mortality is markedly increased in cerebral malaria combined with acidosis. Clinical Trial Registration. ISRCTN50258054.

Aetiological agents of cerebrospinal meningitis: a retrospective study from a teaching hospital in Ghana.

BACKGROUND: Meningitis is an important cause of morbidity and mortality in low-resource settings. In sub-Saharan Africa, the meningitis belt has been characterized by particularly high and seasonal incidences of bacterial meningitis extending throughout life. Despite the progress being made in treating the condition, the mortality rates continue to be high, ranging between 2% and 30% globally. In Ghana, the mortality rate of meningitis has been estimated to range from 36% to 50%. However little information is available on the pathogens contributing to meningitis and their antimicrobial susceptibilities. Updated information is essential to adjust the recommendations for empirical treatment or prevention of meningitis which could have immense implications for local and global health. METHODS: We retrospectively reviewed laboratory records of all patients suspected of bacterial meningitis who underwent a lumbar puncture from January 1, 2008 to December 31, 2010. Data were retrieved from laboratory record books and double entered into a Microsoft(®) excel spreadsheet. RESULTS: Records of 4,955 cerebrospinal fluid samples were analysed. Of these, 163 (3.3%, 95%CI: 2.8% to 3.8%) were confirmed meningitis and 106 (2.1%, 95%CI: 1.7% to 2.6%) were probable meningitis cases. Confirmed meningitis cases were made up of 117 (71.8%) culture positive bacteria, 19 (11.7%) culture positive Cryptococcus neoformans and 27(16.6%) Gram positive bacteria with negative culture. The most prevalent bacteria was Streptococcus pneumoniae 91 (77.7%), followed by E.coli 4 (3.4%), Salmonella species 4 (3.4%), Neisseria meningitidis 3 (2.5%), Pseudomonas species 3(2.5%) and others. Pneumococcal isolates susceptibility to penicillin, chloramphenicol and ceftriaxone were 98.9% (95%CI: 94.0% to 100.0%), 83.0% (95%CI: 73.4% to 90.1%) and 100.0% (95%CI: 95.8% to 100.0%) respectively. CONCLUSION: Streptococcus pneumoniae is an important cause of meningitis among all age groups and its susceptibility to penicillin and ceftriaxone still remains very high. Ghanaians of all ages and possibly other developing countries in the meningitis belt could benefit from the use of the pneumococcal vaccine. Other bacterial and fungal pathogens should also be considered in the management of patients presenting with meningitis.
