In Ghana, the prevalence of chronic kidney disease (CKD) is 28.5% in diabetic hypertensive patients, 26.3% in hypertensives, and 16.1% in those with diabetes only. Trajectories of estimated glomerular filtration rate (eGFR) among patients with hypertension and diabetes are important for monitoring and instituting prompt interventions to prevent the development of CKD, especially in the face of limited access to renal replacement therapy. In this prospective multi-center study conducted at five hospitals in Ghana, we assessed predictors of rapid eGFR progression among adults with hypertension and/or diabetes. Serum creatinine at baseline and 18 months were taken and eGFR determined using the CKD-EPI formula. eGFR trajectory was defined as fast when the decline of GFR was ≥ 5 ml/min/1.73 m

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.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.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.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.

General Medicine - Abstract
Children with sickle cell disease (SCD) have an increased risk of multiple hemotransfusions and this can predispose them to elevated iron stores. The objectives of the study were to determine the extent of elevated iron stores and the associated risk factors in a population of steady-state SCD children in Ghana.This cross-sectional study was conducted at the pediatric sickle cell clinic at the Komfo Anokye Teaching Hospital. Complete blood count and serum ferritin assay were performed for (The mean (standard deviation) age of the participants was 9.61 (±4.34) years, and 51% of them were males. About 17% of SCD children had elevated iron stores and receiving at least three hemotransfusions during the last 12 months was strongly associated with elevated iron stores (The magnitude of elevated iron stores was high among children with SCD in steady-state. Red cell indices could provide invaluable information regarding the risk of elevated iron stores. SCD children who have a history of chronic hemotransfusion or had received at least three hemotransfusions in a year should be monitored for elevated iron stores.

Introduction: Weight estimation in children is critical in paediatric emergencies. The Broselow Tape (BT) and most age-based formulae for weight estimation were derived in high-income countries and are thought to overestimate the weight of children in low-income countries. This study sought to validate the 2017 BT, and eight age-based weight estimation formulae among Ghanaian children and to derive a weight estimation formula using this data. Methods: A cross-sectional study was conducted in the Tamale Teaching Hospital (TTH) in Ghana. Children aged between 2 months and 13 years had their weights estimated by the 2017 BT and eight age-based formulae. These estimated weights were compared to the weight of the children measured by a calibrated Seca scale using mean percentage error (MPE) and the percentage of weight estimates within 10% and 20% of actual weight. Bland-Altman method was used to assess agreement between estimated and actual weight of the children. A new formula was derived by linear regression. Results: Seven hundred and seventy-five children took part in the study. The 2017 BT, Original APLS (APLS1) and Nelson's formulae performed best with proportion of weight estimates within 10% of actual weight being 47.5%, 51.1% and 47.5% respectively. The formula developed in this study was: WE = 3Am / 10 + 5 (for infants

Individuals with HIV are predisposed to depression but there is limited data on its dynamics and correlates. We aimed to assess course and characteristics of depression among Ghanaian HIV patients over a 12-month period. We interrogated a longitudinal study dataset of patients at a tertiary hospital and assessed depression at month 0 and 12 using the Patient Health Questionnaire-9 (PHQ-9). Association between clinical, sociodemographic factors and changes in PHQ-9 scores were evaluated. Among 320 study participants, 171 (53.4%) and 55 (17.2%) had depression at month 0 and 12 respectively. Persistent depression was detected in 41 (24.0%) of the 171 patients with depression at month 0, whilst 135 (42.2%) of them never experienced depression. Patients' CD4 count was associated with depression at month 0 and 12 (p0.05). Predictors of change in depression scores were urban dwelling [-1.98, 95%CI: -3.86 to -0.06, p=0.039], not knowing one's monthly income [2.10, 95%CI: 0.58 to 3.61, p=0.007], participant being single [-1.62 95%CI: -2.45 to -0.78, p0.001] and being on antiretroviral therapy at recruitment [-1.5, 95%CI: -2.55 to -0.45, p0.001]. There was a significant decrease in depression scores over a 12-month period and persistent depression is rife among this cohort of Ghanaians with HIV.

General Medicine - Abstract
Background Pediatric heart diseases (PHDs), comprising congenital heart diseases (CHDs) and acquired heart diseases (AHDs) are significant contributors to non-communicable diseases in children. CHDs alone occur in 0.8-1.0% live births globally. Data on echocardiogram diagnosed PHDs in Ghana however is lacking. We set out to describe the echocardiogram diagnosed prevalence of the various PHDs, their age profile and change in trends over an eleven-year period in children less than sixteen years seen in Kumasi. MethodsWe retrieved archived first echocardiogram scan reports from January 2010 through December 2020, and extracted the diagnosis, scan date and sex of the patients. PHDs were categorized into CHDs and AHDs and proportions of the top five reported respectively. Observed trends in proportion of types of PHDs and age at first diagnosis were computed. Data was collected using Microsoft® Excel and analyzed with R statistical software. ResultsPHDs were present in 49.9% (2474/4962) of the scans done with 51.5% (95%CI: 49.5-53.5) being males and 93.3% CHDs. The number of different diagnoses were 3344 as some of the patients had multiple diagnosis. Of these, the top five CHDs were Ventricular Septal Defect (699, 20.9%), Atrial Septal Defect (634, 19.0%), Patent Ductus Arteriosus (576, 17.2%), Tetralogy of Fallot (318, 9.5%) and Atrio-Ventricular Canal Defect (222, 6.6%). That for AHDs were Rheumatic Heart Disease (61, 1.8%), Dilated Cardiomyopathy (46, 1.4%), pericardial effusion (29, 0.9%), Hypertrophic Cardiomyopathy (26, 0.9%) and Infective Endocarditis (14, 0.4%). Proportion of various PHDs stayed constant over the years (p=0.129). The median (IQR) age in months for acyanotic CHDs (6, 1.5-18), cyanotic CHDs (15.0, 4.0-36.0) and AHDs (72.0, 19.0-120) were significantly different (p

- Abstract
Sickle cell disease (SCD) is the most common clinically significant hemoglobinopathy, characterized by painful episodes, anemia, high risk of infection, and other acute and chronic complications. In Africa, where the disease is most prevalent, large longitudinal data on patients and their outcomes are lacking. This article describes the experiences of the Kumasi Center for SCD at the Komfo Anokye Teaching Hospital (KCSCD-KATH), a Sickle Pan-African Research Consortium (SPARCO) site and a SickleInAfrica Consortium member, in establishing a SCD registry for the evaluation of the outcomes of patients. It also provides a report of a preliminary analysis of the data. The process of developing the registry database involved comprehensive review of the center's SCD patient medical records, incorporating data elements developed by the SickleInAfrica Consortium and obtaining ethical clearance from the local Institutional Review Board. From December 2017 to March 2020, 3,148 SCD patients were enrolled into the SCD registry. Enrollment was during the SCD outpatient clinic visits or through home visits. A significant proportion of the patients was from the newborn screening cohort (50.3%) and was males (52.9%). SCD-SS, SCD-SC, and Sβ

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 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 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.

Background Cardiovascular disease (CVD) poses a significant cause of morbidity and mortality among people living with human immunodeficiency virus (HIV). However, data are limited on CVD risk burden among HIV patients in Ghana. We describe the age‐ and sex‐adjusted prevalence of CVD risk factors among HIV patients in Ghana. Methods From January 2013 to May 2014, we identified eligible HIV patients 18 years and older, as well as uninfected adult blood donors presenting to the Komfo Anokye Teaching Hospital as controls. Using a standardized protocol, we collected demographic, clinical, laboratory, and electrocardiographic data. We created multivariable logistic regression models to compare the prevalence of abnormal risk factors between the two groups. Results We recruited 345 patients with HIV (n = 173 on HAART, n = 172 not on HAART) and 161 uninfected adult blood donors. Patients with HIV were older (mean [SD] age: 41 [11] vs 32 [11] years) and were more likely to be female (72% vs 28%) than blood donors. Among patients on HAART, median (interquartile range) treatment duration was 17 (4‐52) months. The prevalence of hypertension, hypercholesterolemia, and diabetes mellitus among HIV patients was 9%, 29%, and 5%, respectively, compared with 5%, 15%, and 0.6% among uninfected blood donors. Smoking was the least prevalent CVD risk factor (1%‐2%). After adjustment for age, sex, and body mass index, HIV patients had a 10‐fold higher odds of prevalent diabetes compared with controls, (adjusted OR = 10.3 [95% CI: 1.2, 86.7]). Conclusion CVD risk factors are common among HIV patients in Ghana, demonstrating the urgent need for creation and implementation of strategic CVD interventions.

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.

Background: Cervical cancer survivors often experience significant diminution in health-related quality of life (HRQoL). We aimed to investigate the overall HRQoL, determine the role of the stage of disease and type of treatment received on HRQoL, and evaluate predictors of HROoL among cervical cancer survivors in Kumasi, Ghana. Methods: A hospital-based cross-sectional study was conducted in 153 cervical cancer patients who completed curative treatment between January 2004 and December 2018 at Komfo Anokye Teaching Hospital. The European Organization for Research and Treatment of Cancer core questionnaire (EORTC QLQ C-30) supplemented with the cervical cancer-specific (EORTC QLQ-CX24) module was used. The Kruskal-Wallis test was used to determine the effect of the stage of cervical cancer and the type of treatment received on mean scores of the different domains of HRQoL. Multivariate logistic regression was performed to identify predictors of HRQoL. P < 0.05 was considered statistically significant. Results: The mean global health score (GHS) was 79.7 (+/-16.2), and it differed significantly with International Federation of Gynaecology and Obstetrics (FIGO) stage, with 84.1 76.2, and 79.9, for stages I, II and III respectively (p=0.012). Financial burden was higher in participants with FIGO stage II compared to stage I disease (45.4 vs 20.8, p=0.012.). The mean GHS scores for surgery, chemoradiation and radiation only were 85.2, 75.9, and 82.1 respectively (p=0.027). Compared to participants who were treated with Chemoradiation, those treated with surgery had lower financial difficulties (12.1 vs 41.6 , p=0.019), better body image (95.7vs 79.5, p =0.039) and better symptom experience (5.9 vs 12.0, p =0.043).The likelihood that survivors’ GHS is affected is decreased with illiteracy (AOR = 0.30, 95% CI=0.09–1.00), and increased with complaints of pain (AOR=5.50, 95%CI=1.68-18.29), loss of appetite (AOR=13.24, 95% CI=2.71– 64.67) and diminution in body image perception (AOR = 6.04, 95% CI=1.67–21.83). Conclusion: Cervical cancer survivors in Kumasi, Ghana have overall satisfactory HRQoL. Surgical treatment is associated with improved HRQoL and less financial burden. Efforts to enhance HRQoL should also be focused on maximizing survivors’ body image and managing pain and loss of appetite. Educating women about expected impacts on their quality of life, and strategies to manage and mitigate these impacts, is essential.

Background: Lipoprotein(a) [Lp(a)] and high-sensitivity C-reactive protein (hs-CRP) levels are associated with cardiovascular disease (CVD) in the general population, even after adjusting for conventional CVD risk factors. However, data are limited regarding the distribution of Lp(a) and hs-CRP among patients with HIV in Ghana. We explored levels of Lp(a), hs-CRP and other cardiovascular risk factors among people who were HIV positive (HIV+) on ART (HIV+ART+), HIV+ART–, and HIV–ART– in a Ghanaian population.Methods: We conducted a cross sectional study, recruited individuals who were HIV+ART+ and HIV+ART– from the largest HIV clinic in central Ghana between August 2018 and December 2019. HIV negative controls were recruited from communities and adjoining suburbs of Kumasi. Lipoprotein(a) was measured using Immunoturbidimetric assay and high sensitive-CRP concentrations were determined using particle-enhanced turbidimetric assay. We compared levels of Lp(a), hs-CRP, and conventional CVD risk factors among these groups and used multivariable stepwise logistic regression models to explore associations between them.Results: Among HIV+ART+ (n = 156), HIV+ART– (n = 131), and HIV–ART– (n = 147), mean(SD) ages were 48 (9.1) years, 41 (11.1) years and 45 (11.9) years, p = 30mg/dL) were 70%, 48% and 62% among HIV+ART+,HIV+ART– and HIV–ART– participants respectively. Diabetes mellitus, dyslipidemia, waist-to-hip ratio and metabolic syndrome were associated with higher hs-CRP levels. Compared to HIV–ART–, HIV+ patients had higher odds of having hs-CRP > 3mg/L while HIV+ART+ patients had higher odds of elevated Lp(a) than HIV+ART– after multivariable adjustment.Conclusion: PLWHA in Ghana are associated with higher odds of elevated hs-CRP, regardless of ART use. HIV+ART+ is significantly associated with higher odds of elevated Lp(a) levels compared to HIV+ART–; even after multivariable adjustments. Reasons for this and potential clinical implications merit further study.

BACKGROUND: 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. 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 arm. 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

Background Diarrhoeal diseases are among the most frequent causes of morbidity and mortality in children worldwide, especially in sub-Saharan Africa. This case–control study was conducted to investigate the bacterial, viral and parasitic pathogens associated with acute diarrhoea among children attending three health facilities in Kumasi, Ghana. Methods Stool specimens were collected from 240 children under 5 years of age visiting hospitals in Kumasi, Ghana due to acute diarrhoea and from 107 healthy controls of similar age. Both intestinal and malaria parasites were diagnosed by microscopy whereas rota- and adenoviruses were identified by stool antigen immunochromatograhic testing. Bacterial enteropathogens were detected by conventional culture techniques. Results Of all subjects, 23 (6.6%) were positive for malaria parasitaemia, 139 (40.1%) had at least one bacterial agent in their stool and 25 (7.2%) had ova or parasites. Subjects infected with malaria had the highest odds of having diarrhoea [12.0 (95% CI 1.56, 92.35)] followed by those with rotaviruses [4.4 (95% CI 2.05, 9.47)] and bacterial infection [4.99 (95% CI 1.45, 17.17)]. Conclusion In conclusion, this study was unique as it looked at the three groups of pathogens (parasites, viruses and bacteria) that cause acute diarrhoea in children in the Kumasi metropolis of Ghana. This study has shown for the first time since 2004 that malaria parasitaemia, rotavirus and bacterial infections still remain common pathogens associated with acute childhood diarrhoea in the Kumasi metropolis of Ghana.

Background Little is known about the course of perinatal anxiety, particularly in low and middle income countries. This study aimed at examining trajectories of ante- and postpartum generalized anxiety symptoms in West-African women and their associations with mother and child characteristics. Methods 778 women from Cote d’Ivoire and Ghana were investigated between 04/2010 and 03/2014. Anxiety symptoms were measured using the seven-item Generalized Anxiety Disorder scale (GAD-7) at three months antepartum and three, 12 and 24 months postpartum. Growth mixture modeling was applied to identify latent trajectory classes of anxiety. Multinomial logistic regression was used to investigate the associations of psychosocial, sociodemographic, obstetric and clinical characteristics with different trajectories. Results Four distinct trajectories of anxiety were identified. The majority of women (79.8%) had consistent low anxiety symptoms, while 11.4% had elevated anxiety scores before and around childbirth that decreased gradually. 5.4% of women showed increasing anxiety symptoms over time. Few women (3.3%) had transient anxiety with elevated scores at three and 12 months postpartum. Risk factors for elevated anxiety levels around childbirth were antepartum depressive symptoms, higher levels of stress (economic, marital and social stress), lower child birth weight, and multiparity. Partner support was found to be protective. Limitations Anxiety symptoms were assessed using a screening instrument and not through a formal diagnostic classification system. Some putative risk factors were not investigated, and some psychosocial factors were assessed retrospectively. Conclusion The presence of different trajectories underline the importance of monitoring anxiety symptoms in pregnant women and in mothers with infants/toddlers.

Background Uncorrected congenital heart lesions in children keep them in a state of constant hypoxia with compromised quality of life and reduced life expectancy. This requires early diagnosis and interventions including prevention and treatment of the resultant anaemia. Unfortunately, congenital heart disease (CHD) often goes unrecognized and thus untreated. Objectives We determined the occurrence of CHD in children below 15 years at the Komfo Anokye Teaching Hospital (KATH), assessed the prevalence of relative iron deficiency anaemia in that cohort and the use of iron supplementation in these patients. Methods We conducted a cross-sectional study, using a structured data collection tool, by retrospectively reviewing patient records from December 2015 to January 2010. Data was also obtained prospectively from January 2016 to March 2016. Results Eighty cases (44 females and 36 males) of CHD were encountered. Tetralogy of Fallot was the most common (48.8%) CHD. Cases of cyanotic congenital heart disease were reported at autopsy. Of the 80 cases, 48 (72.7%) had signs of relative iron deficiency. Thirty (62.5%) of the 48 patients did not receive iron supplementation. In 14 cases, full blood count was not determined and yet 10 patients received iron at sub-optimal doses (, Health sciences; Cardiology; Cardiovascular system; Emergency medicine; Laboratory medicine; Congenital; Cyanotic; Hypoxia; Erythropoietin; Anaemia

Background: Anogenital distance (AGD) is a simple noninvasive measure of foetal androgen exposure. This study was done to generate normative data on AGD in Ghanaian newborns. Methods: AGD was measured in 644 male and 612 female term newborns; including the distance between the anterior base of the penis and the centre of the anus, the posterior base of the penis and the centre of the anus, and the posterior base of the scrotum and the centre of the anus (ASD) in males and the distance from the anus to the fourchette (AF) and from the anus to the base of the clitoris in females. Other anthropometric and parental socio-demographic indices were also documented. Results: AGD was sexually dimorphic; with a mean ± SD ASD and AF of 25.5 ± 5.1 and 13.6 ± 2.7 mm, respectively. There was a significant correlation between AGD and birth weight, birth length, and occipitofrontal circumference (p < 0.05). ASD was significantly longer (p < 0.001) in newborns (83/644; 12.9%) of mothers who had ingested herbs during pregnancy. Conclusion: AGD was approximately twice as long in males compared to females and can serve as a useful indicator of androgen exposure. Measurements of AGD also need to factor in anthropometric parameters, which are important correlates of AGD.

In low-income countries, perinatal depression is common, but longitudinal data on its influence on child health are rare. We examined the association between maternal depression and febrile illness in children. There were 654 mother/child dyads in Ghana and Côte d'Ivoire that were enrolled in a prospective birth cohort in 2010-2011 and underwent 2-years of follow up. Mothers were examined for depression using the Patient Health Questionnaire depression module antepartum and 3 and 12 months postpartum. The hazard of febrile illness in children of depressed and nondepressed mothers was estimated using a recurrent event Cox proportional hazards model. The prevalences of antepartum depression in mothers from Côte d'Ivoire and Ghana were 28.3% and 26.3%, respectively. The prevalences of depression at 3 and 12 months postpartum were 11.8% and 16.1% (Côte d'Ivoire) and 8.9% and 7.2% (Ghana). The crude and adjusted (for country and socioeconomic status) hazard ratios of febrile illness in children of depressed mothers compared with those in children of nondepressed mothers were 1.57 (95% confidence interval: 1.20, 2.07) and 1.32 (95% confidence interval: 1.01, 1.74) respectively. Perinatal depression was frequent and associated with febrile illness in the offspring. Our results showed that a high prevalence of depression in sub-Saharan Africa may pose a serious public health threat to women and their offspring.

Background The older adult population is increasing all over the world. In sub-Saharan Africa, due to poverty and low policy coverage, older adults are not well catered for. The effect of socio-economic inequality in the use of healthcare services among older adult men and women in Ghana was investigated in this paper. Methods The data employed in the study were drawn from Global Ageing and Adult Health survey SAGE Wave 1 Ghana and was based on the design for the World Health Survey 2003, SAGE Wave 0, Ghana. The survey was conducted in 2007–2008 and collected data on socio-economic characteristics and other variables of the 5573 individuals interviewed. Results Using generalized logit model, the study found that health status is a very strong determinant of the type of healthcare services preferred by older adults Ghanaians. Men with higher income preferred the private health facilities, while those who completed tertiary education, those with health insurance and those who self-rated their health as very bad, bad or moderate preferred public facility. Self-employed men and those in informal employment, preferred other health facilities outside the formal public health service. Women with primary and secondary education, preferred the private health facilities. Women with health insurance, those in middle and upper class income quintiles or those with self-rated bad and moderate health status or being relatively younger preferred the public facility to other health services. Self-employed women and those in informal employment preferred traditional treatment. In Ghana, there are important socio-economic gradients in the use of some healthcare services. In both sexes, those without insurance and rural residents preferred the pharmacy and traditional treatment. Conclusion These differences may be due to socio-economic inequities but could also indicate that the existing health facilities are not always used in an optimal way. Patient factors may be equally important as supply factors in explaining the differential use of health services. The public health systems in Ghana still have a major role in improving the health of older adults. National commitments in providing basic essential infrastructure and personnel to health centres for the citizenry is imperative. Policy readjustment of the national health insurance scheme to make it truly accessible to the aged is essential.

A genome-wide association study in Ghana, West Africa, to identify genetic variants associated with malaria pathogenesis reveals two previously unknown loci on chromosomes 1 and 16. This genome-wide association study in 2,645 cases and 3,050 controls from Ghana in West Africa identifies genetic variants that might affect any one of the many steps in malaria pathogenesis. Two novel loci are described. The first is on chromosome 1, in the vicinity of the ATP2B4 gene, which encodes the main calcium pump of erythrocytes, the host cells of the pathogenic stage of the malaria parasite. The second is on chromosome 16, close to MARVELD3, which encodes a tight-junction protein that is expressed on endothelial cells. These genetic variants may confer resistance by affecting key steps in disease development that could generate possible antimalarial targets. Malaria causes approximately one million fatalities per year, mostly among African children1. Although highlighted by the strong protective effect of the sickle-cell trait2,3, the full impact of human genetics on resistance to the disease remains largely unexplored4. 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 successful5. 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 erythrocytes6, 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 cells7 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 O5,8,9. Our findings underline the potential of the GWA approach to provide candidates for the development of control measures against infectious diseases in humans.

The aim was to assess whether impaired cardiac function contributes to symptoms of severe malaria in general or to metabolic acidosis in particular in children living in endemic regions.In a prospective observational investigation, 183 children with severe malaria were investigated for hemodynamic status and cardiac function upon admission (day 0) and after recovery (day 42). Cardiac function parameters were assessed by cardiac ultrasonography. Blood gas analyses and cardiac enzymes were measured at hospitalization and follow-up. Differences in subgroups with and without metabolic acidosis as well as other severe malaria-defining symptoms and conditions were assessed.Cardiac index (CI) was significantly increased on day 0 compared to day 42 (5.8 ml/m(2), SD ± 1.8 ml/m(2), versus 4.7 ml/m(2), SD ± 1.4 ml/m(2); P0.001). CI correlated negatively with hemoglobin levels but not with parameters indicating impaired tissue perfusion or metabolic acidosis. Parasite levels had a significant influence on metabolic acidosis but not on CI. Alterations related to cardiac function, hemoglobin levels and metabolic acidosis were most prominent in children younger than 2 years.Increased CI reflecting high output status is associated with low hemoglobin levels while metabolic acidosis is linked to parasite levels.

Malaria remains the single most frequent cause of death in Africa, killing one child every 30 s, but treatment decisions are often made only on clinical diagnosis, as laboratory techniques to confirm the clinical suspicion are labor intensive and costly. In this study, we evaluated the recently developed Partec rapid malaria test (PM) for the detection of Plasmodium spp. in human blood from patients in an area where malaria is endemic and compared the results with those of thick blood film Giemsa stain (GS) in terms of its performance and operational characteristics, using real-time (RT) PCR as the gold standard. The sensitivities of the PM and the GS were 62.2% (95% CI, 56.3 to 67.8) and 61.8% (95% CI, 55.9 to 67.4), respectively, while the specificities were 96.0% (95% CI, 92.3 to 98.3) and 98% (95% CI, 95.0 to 99.5), respectively. There was an excellent agreement between the results for the PM and those of the GS ( k [level of agreement] = 0.96; P < 0.001). The results for the PM were obtained more quickly and at less cost than those for the GS. The performance characteristics of the PM were almost equal to those of the GS, but the operational characteristics were better, and the PM can therefore be considered as an alternative method for GS.

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.

Background While several anti-malarials are known to affect the electric conduction system of the heart, less is known on the direct effects of Plasmodium falciparum infection. Some earlier studies point to a direct impact of Plasmodium falciparum infection on the electric conduction system of the heart. The aim of this study was to analyse infection- and drug-induced effects on the electric conduction system. Methods Children aged 12 months to 108 months with severe malaria were included in Kumasi, Ghana.

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.

The article here investigated the impact of Preventive Health Behaviors and Risk Factors as measures of Health Status of Ghanaians. We carry out a cross-sectional analysis of 5573 adults who participated and had indicated that they needed to state their health description in the three years prior to the phase 2007 World Health Organization, a study on Global Ageing and Adult health (SAGE) conducted in Ghana. The ordinal logistic regression model was employed for analysis using R. The results suggest that, there is incontrovertible evidence showing a strong relationship between preventive health behaviors and health status of Ghanaians. Again, the lifestyle of Ghanaians clearly manifests in their positive correlation with the good and moderate health state due to the high percentage (38.96% and 39.04%) respectively. The outcome points to a potential link with the Ghanaian social and health policies.

Socio-economic predictors of chronic diseases in Ghana are not well understood and their influence has been relatively overlooked. This paper seeks to examine the influence of socio-economic predictors of chronic diseases in Ghanaians three different age groups. The data employed in the study were drawn from Global Ageing and Adult Health survey conducted in Ghana by SAGE and was based on the design for the World Health Survey. The survey was conducted in 2007 and collected data on socio-economic characteristics and other variables of the individuals interviewed. The overall results suggest that chronic diseases in relatively older Ghanaians reflects social and economic exposures with the differentials observed only partially explained by current social and economic conditions. Our results were by and large very much expected from the current medical knowledge available.

BackgroundEvidence linking common mental disorders (CMD) in pregnant women to adverse birth outcomes is inconsistent, and studies often failed to control for pregnancy complications. This study aimed to explore the association between antenatal depression and anxiety symptoms and birth outcomes in a low-obstetric risk sample of mother/child dyads in Ghana and Côte d'Ivoire.MethodsIn 2010-2011, a prospective cohort of 1030 women in their third trimester in Ghana and Côte d'Ivoire was enrolled. Depression and anxiety were assessed in the third trimester using the Patient Health Questionnaire depression module and the 7-item Generalized Anxiety Disorder scale. 719 mother/child dyads were included in the analysis. We constructed multivariate regression models to estimate the association between CMD and low birth weight (LBW), and preterm birth (PTB) to control for potential confounders.ResultsThe prevalence of depression and anxiety symptoms were 28.9% and 14.2% respectively. The mean birth weight was 3172.1g (SD 440.6) and the prevalence of LBW was 1.7%. The mean gestational age was 39.6 weeks and the proportion of PTB was 4%. Multivariate linear regression revealed no significant association between maternal depression (B=52.2, 95% CI -18.2 122.6, p=0.15) or anxiety (B=17.1, 95% CI -74.6 108.7, p=0.72) and birth weight. Yet, low socio-economic status, female sex of the child, and younger maternal age were associated with lower birth weight. Multivariate logistic regression suggested no significant association between maternal depression (OR: 2.1, 95% CI 0.8 5.6, p=0.15) or anxiety (OR: 1.8, 95% CI 0.6 5.5, p=0.29) with PTB.ConclusionsOur data suggests that depression and/or anxiety in the 3(rd) trimester of pregnancy are not independent predictors of adverse birth outcomes in low obstetric risk women. The role of pregnancy complications as confounders or effect modifiers in studies of maternal CMD and their impact on birth outcomes should be investigated.

Summary Background Malaria is one of the greatest causes of mortality worldwide. Use of the most effective treatments for malaria remains inadequate for those in need, and there is concern over the emergence of resistance to these treatments. In 2010, the Global Fund launched the Affordable Medicines Facility—malaria (AMFm), a series of national-scale pilot programmes designed to increase the access and use of quality-assured artemisinin based combination therapies (QAACTs) and reduce that of artemisinin monotherapies for treatment of malaria. AMFm involves manufacturer price negotiations, subsidies on the manufacturer price of each treatment purchased, and supporting interventions such as communications campaigns. We present findings on the effect of AMFm on QAACT price, availability, and market share, 6–15 months after the delivery of subsidised ACTs in Ghana, Kenya, Madagascar, Niger, Nigeria, Uganda, and Tanzania (including Zanzibar). Methods We did nationally representative baseline and endpoint surveys of public and private sector outlets that stock antimalarial treatments. QAACTs were identified on the basis of the Global Fund's quality assurance policy. Changes in availability, price, and market share were assessed against specified success benchmarks for 1 year of AMFm implementation. Key informant interviews and document reviews recorded contextual factors and the implementation process. Findings In all pilots except Niger and Madagascar, there were large increases in QAACT availability (25·8–51·9 percentage points), and market share (15·9–40·3 percentage points), driven mainly by changes in the private for-profit sector. Large falls in median price for QAACTs per adult equivalent dose were seen in the private for-profit sector in six pilots, ranging from US$1·28 to $4·82. The market share of oral artemisinin monotherapies decreased in Nigeria and Zanzibar, the two pilots where it was more than 5% at baseline. Interpretation Subsidies combined with supporting interventions can be effective in rapidly improving availability, price, and market share of QAACTs, particularly in the private for-profit sector. Decisions about the future of AMFm should also consider the effect on use in vulnerable populations, access to malaria diagnostics, and cost-effectiveness.

Background Acute respiratory tract infections are one of the major causes of morbidity and mortality among young children in developing countries. Information on the viral aetiology of acute respiratory infections in developing countries is very limited. The study was done to identify viruses associated with acute lower respiratory tract infection among children less than 5 years. Method Nasopharyngeal samples and blood cultures were collected from children less than 5 years who have been hospitalized for acute lower respiratory tract infection. Viruses and bacteria were identified using Reverse Transcriptase Real-Time Polymerase Chain Reaction and conventional biochemical techniques. Results Out of 128 patients recruited, 33(25.88%%, 95%CI: 18.5% to 34.2%) were positive for one or more viruses. Respiratory Syncytial Virus (RSV) was detected in 18(14.1%, 95%CI: 8.5% to 21.3%) patients followed by Adenoviruses (AdV) in 13(10.2%, 95%CI: 5.5% to 16.7%), Parainfluenza (PIV type: 1, 2, 3) in 4(3.1%, 95%CI: 0.9% to 7.8%) and influenza B viruses in 1(0.8%, 95%CI: 0.0 to 4.3). Concomitant viral and bacterial co-infection occurred in two patients. There were no detectable significant differences in the clinical signs, symptoms and severity for the various pathogens isolated. A total of 61.1% (22/36) of positive viruses were detected during the rainy season and Respiratory Syncytial Virus was the most predominant. Conclusion The study has demonstrated an important burden of respiratory viruses as major causes of childhood acute respiratory infection in a tertiary health institution in Ghana. The data addresses a need for more studies on viral associated respiratory tract infection.

Background About 90% of all malaria deaths in sub-Saharan Africa occur in children under five years. Fast and reliable diagnosis of malaria requires confirmation of the presence of malaria parasites in the blood of patients with fever or history suggestive of malaria; hence a prompt and accurate diagnosis of malaria is the key to effective disease management. Confirmation of malaria infection requires the availability of a rapid, sensitive, and specific testing at an affordable cost. We compared two recent methods (the novel Partec Rapid Malaria Test® (PT) and the Binax Now® Malaria Rapid Diagnostic Test (BN RDT) with the conventional Giemsa stain microscopy (GM) for the diagnosis of malaria among children in a clinical laboratory of a hospital in a rural endemic area of Ghana. Methods Blood samples were collected from 263 children admitted with fever or a history of fever to the pediatric clinic of the Agogo Presbyterian Hospital. The three different test methods PT, BN RDT and GM were performed independently by well trained and competent laboratory staff to assess the presence of malaria parasites. Results were analyzed and compared using GM as the reference standard. Results In 107 (40.7%) of 263 study participants, Plasmodium sp. was detected by GM. PT and BN RDT showed positive results in 111 (42.2%) and 114 (43.4%), respectively. Compared to GM reference standard, the sensitivities of the PT and BN RDT were 100% (95% CI: 96.6-100) and 97.2% (95% CI: 92.0-99.4), respectively, specificities were 97.4% (95% CI: 93.6-99.3) and 93.6% (95% CI: 88.5-96.9), respectively. There was a strong agreement (kappa) between the applied test methods (GM vs PT: 0.97; p < 0.001 and GM vs BN RDT: 0.90; p < 0.001). The average turnaround time per tests was 17 minutes. Conclusion In this study two rapid malaria tests, PT and BN RDT, demonstrated a good quality of their performance compared to conventional GM. Both methods require little training, have short turnaround times, are applicable as well as affordable and can therefore be considered as alternative diagnostic tools in malaria endemic areas. The species of Plasmodium cannot be identified.

Background In resource poor settings where automated hematology analyzers are not available, the Cyanmethemoglobin method is often used. This method though cheaper, takes more time. In blood donations, the semi-quantitative gravimetric copper sulfate method which is very easy and inexpensive may be used but does not provide an acceptable degree of accuracy. The HemoCue® hemoglobin photometer has been used for these purposes. This study was conducted to generate data to support or refute its use as a point-of-care device for hemoglobin estimation in mobile blood donations and critical care areas in health facilities. Method EDTA blood was collected from study participants drawn from five groups: pre-school children, school children, pregnant women, non-pregnant women and men. Blood collected was immediately processed to estimate the hemoglobin concentration using three different methods (HemoCue®, Sysmex KX21N and Cyanmethemoglobin). Agreement between the test methods was assessed by the method of Bland and Altman. The Intraclass correlation coefficient (ICC) was used to determine the within subject variability of measured hemoglobin. Results Of 398 subjects, 42% were males with the overall mean age being 19.4 years. The overall mean hemoglobin as estimated by each method was 10.4 g/dl for HemoCue, 10.3 g/dl for Sysmex KX21N and 10.3 g/dl for Cyanmethemoglobin. Pairwise analysis revealed that the hemoglobin determined by the HemoCue method was higher than that measured by the KX21N and Cyanmethemoglobin. Comparing the hemoglobin determined by the HemoCue to Cyanmethemoglobin, the concordance correlation coefficient was 0.995 (95% CI: 0.994-0.996, p < 0.001). The Bland and Altman's limit of agreement was -0.389 - 0.644 g/dl with the mean difference being 0.127 (95% CI: 0.102-0.153) and a non-significant difference in variability between the two measurements (p = 0.843). After adjusting to assess the effect of other possible confounders such as sex, age and category of person, there was no significant difference in the hemoglobin determined by the HemoCue compared to Cyanmethemoglobin (coef = -0.127, 95% CI: -0.379 - 0.634). Conclusion Hemoglobin determined by the HemoCue method is comparable to that determined by the other methods. The HemoCue photometer is therefore recommended for use as on-the-spot device for determining hemoglobin in resource poor setting.

Background Malaria is the leading cause of morbidity and mortality in post-conflict Burundi. To counter the increasing challenge of anti-malarial drug resistance and improve highly effective treatment Burundi adopted artesunate-amodiaquine (AS-AQ) as first-line treatment for uncomplicated Plasmodium falciparum malaria and oral quinine as second-line treatment in its national treatment policy in 2003. Uptake of this policy in the public, private and non-governmental (NGO) retail market sectors of Burundi is relatively unknown. This study was conducted to evaluate access to national policy recommended anti-malarials. Methods Adapting a standardized methodology developed by Health Action International/World Health Organization (HAI/WHO), a cross-sectional survey of 70 (24 public, 36 private, and 10 NGO) medicine outlets was conducted in three regions of Burundi, representing different levels of transmission of malaria. The availability on day of the survey, the median prices, and affordability (in terms of number of days' wages to purchase treatment) of AS-AQ, quinine and other anti-malarials were calculated. Results Anti-malarials were stocked in all outlets surveyed. AS-AQ was available in 87.5%, 33.3%, and 90% of public, private, and NGO retail outlets, respectively. Quinine was the most common anti-malarial found in all outlet types. Non-policy recommended anti-malarials were mainly found in the private outlets (38.9%) compared to public (4.2%) and NGO (0%) outlets. The median price of a course of AS-AQ was US$0.16 (200 Burundi Francs, FBu) for the public and NGO markets, and 3.5-fold higher in the private sector (US$0.56 or 700 FBu). Quinine tablets were similarly priced in the public (US$1.53 or 1,892.50 FBu), private and NGO sectors (both US$1.61 or 2,000 FBu). Non-policy anti-malarials were priced 50-fold higher than the price of AS-AQ in the public sector. A course of AS-AQ was affordable at 0.4 of a day's wage in the public and NGO sectors, whereas, it was equivalent to 1.5 days worth of wages in the private sector. Conclusions AS-AQ was widely available and affordable in the public and NGO markets of hard-to-reach post-conflict communities in Burundi. However greater accessibility and affordability of policy recommended anti-malarials in the private market sector is needed to improve country-wide policy uptake.

Maternal mortality ratio averages 230 per 100,000 live births in developing countries. Obstructed labour, which is a major cause results from prolonged, neglected labour. The partograph as recommended by the World Health Organization is a graphical tool used to monitor the progress of the first stage of labour, thereby preventing prolonged labour. The partograph has been in use in Ghana since 1989. The study was conducted to ascertain the proportion and correct use of the partograph in monitoring labours in 4 hospitals in a metropolitan area of Ghana. Partograph use for labour monitoring averaged 54% in this study. Midwives formed 90% of birth attendants. For the progress of labour, parameters were monitored to standard in 55-60% of cases. Parameters pertaining to fetal well being were correctly monitored in 30-50%. Maternal well being was monitored to standard in 40% of cases. Apgar scores at 1 and 5 minutes did not differ whether parameters were recorded to standard or not. We conclude from our study that almost half of labour cases were not monitored with the partograph. In those that were monitored with the partograph monitoring to standard was done in 40-60%. Birth attendants either lack the skill in charting the partograph to standard protocols or do not appreciate the use of the partograph in monitoring the progress of labour. In resourcelimited centres in the developing world the use of the partograph to monitor the progress of labour cannot be overemphasized. Skilled attendants at deliveries must therefore be given regular updates on the proper use of the partograph during labours.

BackgroundIn Ghana, 32% of deliveries take place outside a health facility, and birth weight is not measured. Low birth weight (LBW) newborns who are at increased risk of death and disability, are not identified; 13%-14% of newborns in Ghana are LBW. We aimed at determining whether alternative anthropometrics could be used to identify LBW newborns when weighing scales are not available to measure birth weight.MethodsWe studied 973 mother and newborn pairs at the Komfo Anokye Teaching and the Suntreso Government hospitals between November 2011 and October 2012. We used standard techniques to record anthropometric measurements of newborns within 24 hours of birth; low birth weight was defined as birth weight ResultsOne-fifth (21.7%) of newborns weighed less than 2.5 kg. Among LBW newborns, the following measurements had the highest correlations with birth weight: chest circumference (r = 0.69), mid-upper arm circumference (r = 0.68) and calf circumference (r = 0.66); the areas under the curves of these three measurements demonstrated the highest accuracy in determining LBW newborns. Chest, mid-upper arm and calf circumferences at cut-off values of ≤ 29.8 cm, ≤ 9.4 cm and ≤ 9.5 cm respectively, had the best combination of maximum sensitivity, specificity and predictive values for identifying newborns with LBW.ConclusionsAnthropometric measurements, such as the chest circumference, mid-upper arm circumference and calf circumference, offer an opportunity for the identification of and subsequent support for LBW newborns in settings in Ghana, where birth weights are not measured by standardized weighing scales.

Purpose: Oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor 2 (HER2/neu) expression in breast cancer patients predict response to chemotherapy though recorded extent vary. This retrospective study aimed to investigate the relationship between ER, PR and HER2/neu expression and response of breast cancer to chemotherapy at a tertiary hospital in Ghana. Methods: Records of all breast cancer cases seen from 2009 through 2011 were reviewed. Their receptor status, first line treatment [4 cycles of Adriamycin (60mg/m2) + Cyclophosphamide (600mg/m2)], second line treatment [Capecitabine (1g/m2) + Paclitaxel (170mg/m2)] and clinical response were extracted.Results: Complete remission after first and second line treatments were observed in 36 (38.3%, 95% CI: 28.5 to 48.9) and 34 (58.6%, 95% CI: .44.9 to 71.4) respectively. After both first and second line treatment 70 (74.5%, 95% CI: 64.4 - 82.9) had gone into remission. Prevalence of ER, PR, HER2/neu and Triple negative breast cancer (TNBC) were 34.0% (95% CI: 24.6 to 44.5), 20.2% (95% CI: 12.6 to 29.7), 8.5% (95% CI: 3.7 to 16.1) and 59.6% (95%CI: 48.9 to 69.6) respectively. ER and PR positivity were independently associated with complete remission after first line treatment while TNBC was associated with non-remission. Conversely ER was independently associated with non-remission after second line treatment while TNBC was associated with complete remission. Conclusion: ER and TNBC status are significant predictors of complete remission and non-remission respectively after chemotherapy for breast cancer patient in Ghana.................................................................Cite this article as:Amankwaa-Frempong E, Yeboah FA, Nguah SB, Afriyie OO.

Background Data on cancers is a challenge in most developing countries. Population-based cancer registries are also not common in developing countries despite the usefulness of such registries in informing cancer prevention and control programmes. The availability of population-based data on cancers in Africa varies across different countries. In Ghana, data and research on cancer have focussed on specific cancers and have been hospital-based with no reference population. The Kumasi Cancer Registry was established as the first population-based cancer registry in Ghana in 2012 to provide information on cancer cases seen in the city of Kumasi. Methods This paper reviews data from the Kumasi Cancer Registry for the year 2012. The reference geographic area for the registry is the city of Kumasi as designated by the 2010 Ghana Population and Housing Census. Data was from all clinical departments of the Komfo Anokye Teaching Hospital, Pathology Laboratory Results, Death Certificates and the Kumasi South Regional Hospital. Data was abstracted and entered into Canreg 5 database. Analysis was conducted using Canreg 5, Microsoft Excel and Epi Info Version 7.1.2.0. Results The majority of cancers were recorded among females accounting for 69.6% of all cases. The mean age at diagnosis for all cases was 51.6 years. Among males, the mean age at diagnosis was 48.4 compared with 53.0 years for females. The commonest cancers among males were cancers of the Liver (21.1%), Prostate (13.2%), Lung (5.3%) and Stomach (5.3%). Among females, the commonest cancers were cancers of the Breast (33.9%), Cervix (29.4%), Ovary (11.3%) and Endometrium (4.5%). Histology of the primary tumour was the basis of diagnosis in 74% of cases with clinical and other investigations accounting for 17% and 9% respectively. The estimated cancer incidence Age Adjusted Standardised Rate for males was 10.9/100,000 and 22.4/100, 000 for females. Conclusion This first attempt at population-based cancer registration in Ghana indicates that such registries are feasible in resource limited settings as ours. Strengthening Public Health Surveillance and establishing more Population-based Cancer Registries will help improve data quality and national efforts at cancer prevention and control in Ghana.

Ectopic pregnancies complicate 1-2% of pregnancies and are potentially fatal as rupture causes severe intra-peritoneal haemorrhage. Both major and minor risk factors have been known for several years. These include damage to the fallopian tubes following previous pelvic infections and tubal surgery. Being fair colored in black women has been suspected to be a risk factor in Ghana for several years despite this not being found in any literature search. A matched case controlled study conducted in Ghana to ascertain this found a highly significant association between ectopic pregnancy and fair skin complexion (p < 0.001 at 95% confidence intervals) irrespective of whether the fairness is natural or artificially induced with skin bleaching creams and soaps. The study found no association between ectopic pregnancy and previous pelvic surgery (p= 0.389), neither was there any association with lifetime sexual partners (p=0.383), previous pelvic infections (p= 0.389) or previous termination of pregnancy (p-value 0.485).

Malaria remains the leading burden of disease in post-conflict Sierra Leone. To overcome the challenge of anti-malarial drug resistance and improve effective treatment, Sierra Leone adopted artemisinin-combination therapy artesunate-amodiaquine (AS+AQ) as first-line treatment for uncomplicated P. falciparum malaria. Other national policy anti-malarials include artemether-lumefantrine (AL) as an alternative to AS+AQ, quinine and artemether for treatment of complicated malaria; and sulphadoxine-pyrimethamine (SP) for intermittent preventive treatment (IPTp). This study was conducted to evaluate access to national policy recommended anti-malarials. A cross-sectional survey of 127 medicine outlets (public, private and NGO) was conducted in urban and rural areas. The availability on the day of the survey, median prices, and affordability policy and available non-policy anti-malarials were calculated. Anti-malarials were stocked in 79% of all outlets surveyed. AS+AQ was widely available in public medicine outlets; AL was only available in the private and NGO sectors. Quinine was available in nearly two-thirds of public and NGO outlets and over one-third of private outlets. SP was widely available in all outlets. Non-policy anti-malarials were predominantly available in the private outlets. AS+AQ in the public sector was widely offered for free. Among the anti-malarials sold at a cost, the same median price of a course of AS+AQ (US$1.56), quinine tablets (US$0.63), were found in both the public and private sectors. Quinine injection had a median cost of US$0.31 in the public sector and US$0.47 in the private sector, while SP had a median cost of US$0.31 in the public sector compared to US$ 0.63 in the private sector. Non-policy anti-malarials were more affordable than first-line AS+AQ in all sectors. A course of AS+AQ was affordable at nearly two days' worth of wages in both the public and private sectors.

The Affordable Medicines Facility - malaria (AMFm), hosted by the Global Fund to Fight AIDS, Tuberculosis and Malaria, is a financing mechanism which subsidizes quality-assured Artemisinin-based Combination Therapies (ACTs) for distribution to the public and private sectors, complemented by supporting interventions to promote rational drug use. AMFm has been in operation since mid-2010 in eight national-scale operational pilots in Ghana, Kenya, Madagascar, Niger, Nigeria, Tanzania mainland, Uganda and Zanzibar. By March 2012, over 220 million co-paid ACT treatment doses had been ordered. The Independent Evaluation (IE) of AMFm Phase 1 was commissioned by the Global Fund to assess the impact of AMFm on availability, price, market share and use of quality-assured ACTs in all the operational pilots as part of evidence gathering needed to inform decisions regarding the future of the AMFm. The assessment is based on a pre- and post-test design with detailed documentation of the implementation process and context, treating each pilot independently. In each pilot, a nationally representative survey of outlets stocking antimalarial medicines was conducted at the baseline (2009/10) and the endline (2011). In Ghana, the IE was carried out by a team comprising collaborators from the Komfo Anokye Teaching Hospital, Drugs for Neglected Diseases initiative, ICF International and London School of Hygiene and Tropical Medicine. As part of the IE, national level baseline and endline outlet surveys were conducted in Ghana involving the collection and analysis of primary data to answer three questions related to the availability, affordability and market share of quality-assured ACTs using a cluster sampling approach. In-depth key informant interviews were also conducted to provide the necessary context information to help in the interpretation of the survey results. In Ghana, 1,241 and 1,093 outlets were enumerated for the baseline and endline outlet surveys respectively. For the baseline survey, 57.3% (CI: 50.5-64) of outlets with any antimalarials in stock at the time of the survey visit carried artemisinin monotherapies, while only 30.7% (CI: 26.1-35.8) of interviewed outlets had quality-assured ACTs in stock at the time of the survey visit. At baseline, the median cost to patients of one adult equivalent treatment dose of quality-assured ACTs was US$ 3.42 (IQR: 2.4-7.53) for 1,092 products. Detailed results on changes in quality-assured ACT availability, price and market share over a 14-month period between baseline and endline surveys in Ghana will be presented.

s 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.

Background The practice of Kangaroo Mother Care (KMC) is life saving in babies weighing less than 2000 g. Little is known about mothers' continued unsupervised practice after discharge from hospitals. This study aimed to evaluate its in-hospital and continued practice in the community among mothers of low birth weight (LBW) infants discharged from two hospitals in Kumasi, Ghana. Methods A longitudinal study of 202 mothers and their inpatient LBW neonates was conducted from November 2009 to May 2010. Mothers were interviewed at recruitment to ascertain their knowledge of KMC, and then oriented on its practice. After discharge, the mothers reported at weekly intervals for four follow up visits where data about their perceptions, attitudes and practices of KMC were recorded. A repeated measure logistic regression analysis was done to assess variability in the binary responses at the various reviews visits. Results At recruitment 23 (11.4%, 95%CI: 7.4 to 16.6%) mothers knew about KMC. At discharge 95.5% were willing to continue KMC at home with 93.1% willing to practice at night. 95.5% thought KMC was beneficial to them and 96.0% beneficial to their babies. 98.0% would recommend KMC to other mothers with 71.8% willing to practice KMC outdoors. At first follow up visit 99.5% (181) were still practicing either intermittent or continuous KMC. This proportion did not change significantly over the four weeks (OR: 1.4, 95%CI: 0.6 to 3.3, p-value: 0.333). Over the four weeks, increasingly more mothers practiced KMC at night (OR: 1.7, 95%CI: 1.2 to 2.6, p = 0.005), outside their homes (OR: 2.4, 95%CI: 1.7 to 3.3, p < 0.001) and received spousal help (OR: 1.6, 95%CI: 1.1 to 2.4, p = 0.007). Household chores and potentially negative community perceptions of KMC did not affect its practice with odds of 0.8 (95%CI: 0.5 to 1.2, p = 0.282) and 1.0 (95%CI: 0.6 to 1.7, p = 0.934) respectively. During the follow-up period the neonates gained 23.7 sg (95%CI: 22.6 g to 24.7 g) per day. Conclusion Maternal knowledge of KMC was low at outset. Once initiated mothers continued practicing KMC in hospital and at home with their infants gaining optimal weight. Continued KMC practice was not affected by perceived community attitudes.
