Abstract
Diabetes related amputations remain a major global problem, with devastating complications. We critically appraised relevant literature to quantify the prevalence of diabetes related amputations in sub-Saharan Africa (SSA). An electronic search was performed using the EMBASE and PubMed databases until 2020. Twenty-four out of 834 studies retrieved were included. The pooled prevalence of diabetic-related amputations was 36.9% (95%CI: 32.9%-40.8%). Complications of diabetes related amputations included infection, anaemia, foot deformity and mortality. The study revealed a substantial contribution of diabetes to the burden of amputations in SSA and suggests the need for further studies to assess how to reduce the incidence of diabetes, reduce the incidence of and or delay the progression of macro and microvascular complications of diabetes in SSA.

Abstract
OBJECTIVES To provide lay information about genetics and sickle cell disease (SCD) and to identify and address ethical issues concerning the Sickle Cell Disease Genomics of Africa Network covering autonomy and research decision-making, risk of SCD complications and organ damage, returning of genomic findings, biorepository, data sharing, and healthcare provision for patients with SCD. DESIGN Focus groups using qualitative methods. SETTING Six cities in Ghana, Nigeria and Tanzania within communities and secondary care. PARTICIPANTS Patients, parents/caregivers, healthcare professionals, community leaders and government healthcare representatives. RESULTS Results from 112 participants revealed similar sensitivities and aspirations around genomic research, an inclination towards autonomous decision-making for research, concerns about biobanking, anonymity in data sharing, and a preference for receiving individual genomic results. Furthermore, inadequate healthcare for patients with SCD was emphasised. CONCLUSIONS Our findings revealed the eagerness of patients and parents/caregivers to participate in genomics research in Africa, with advice from community leaders and reassurance from health professionals and policy-makers, despite their apprehensions regarding healthcare systems.

Abstract
OBJECTIVE This study aimed to uncover genetic contributors to adiposity in early life. METHODS A genome-wide association study of childhood body fatness in 34,401 individuals within the Nurses' Health Studies and the Health Professionals Follow-up Study was conducted. Data were imputed to the 1000 Genomes Phase 3 version 5 reference panel. RESULTS A total of 1,354 single-nucleotide polymorphisms (P < 10-4 ) were selected for replication in a previously published genome-wide association study of childhood BMI. Nineteen significant genome-wide (P < 5 × 10-8 ) regions were observed, fourteen of which were previously associated with childhood obesity and five were novel: BNDF (P = 7.58 × 10-13 ), PRKD1 (P = 1.43 × 10-10 ), 20p13 (P = 2.05 × 10-10 ), FHIT (P = 1.77 × 10-8 ), and LOC101927575 (P = 3.22 × 10-8 ). The BNDF, FHIT, and PRKD1 regions were previously associated with adult BMI. LOC101927575 and 20p13 regions have not previously been associated with adiposity phenotypes. In a transcriptome-wide analysis, associations for POMC at 2p23.3 (P = 3.36 × 10-6 ) and with TMEM18 at 2p25.3 (P = 3.53 × 10-7 ) were observed. Childhood body fatness was genetically correlated with hip (rg = 0.42, P = 4.44 × 10-16 ) and waist circumference (rg = 0.39, P = 5.56 × 10-16 ), as well as age at menarche (rg = -0.37, P = 7.96 × 10-19 ). CONCLUSIONS Additional loci that contribute to childhood adiposity were identified, further explicating its genetic architecture.

Abstract
BACKGROUND Campylobacter infections in HIV positive patients often present with substantial mortality and morbidity when compared to HIV negative patients. AIM This study assessed the prevalence of Campylobacter, antibiotic resistance phenotypes and genetic factors, and risk of Campylobacter infection associated with living in close proximity to domestic animals in HIV patients with gastric enteritis at Korle-Bu Teaching Hospital, Accra, Ghana. METHODS Resistance to different antibiotics was assessed with Kirby-Bauer disk diffusion method. In addition, all the Campylobacter isolates were tested for ampicillin (blaOXA-61), erythromycin (aph-3-1), tetracycline tet(O), streptomycin (aadE), and the energy-dependent multi-drug efflux pump (cmeB) resistance genes using multiplex polymerase chain reaction. RESULTS Out of a total of 140 (97 females and 43 males) tested patients, 71 (50.7%) patients were positive for Campylobacter coli. Female patients aged within 31-40 years (31.6%) and 41-50 years (31.6%) had high frequency of Campylobacter infection. Most of the infected patients lived in close proximity to chickens (53.5%), however, some patients (14.1%) lived in close proximity to goats. Phenotypic resistance evaluation revealed widespread resistance to ampicillin (100%), tetracycline (100%), ciprofloxacin (71.8%), erythromycin (69%), and gentamicin (49.3%). However, limited no of isolates contained blaOXA-61 (1.41%), cmeB (7.0%) and tet(O (7.0%) resistance genes. CONCLUSION HIV patients with gastric enteritis were infected with resistant Campylobacter coli. Further studies are required to examine correlation of infected patients with C. coli and risk of living in close proximity to poultry birds. There is the need for routine investigation of Campylobacter in patients with gastroenteritis in order to assist in the development of strategies for combating diseases involving resistant zoonotic bacteria strains.

Abstract
Sickle cell disease (SCD) is one of the most common blood disorders impacting planetary health. Over 300,000 newborns are diagnosed with SCD each year globally, with an increasing trend. The sickle cell disease ontology (SCDO) is the most comprehensive multidisciplinary SCD knowledge portal. The SCDO was collaboratively developed by the SCDO working group, which includes experts in SCD and data standards from across the globe. This expert review presents highlights and lessons learned from the fourth SCDO workshop that marked the beginning of applications toward planetary health impact, and with an eye to empower and cultivate multisite SCD collaborative research. The workshop was organized by the Sickle Africa Data Coordinating Center (SADaCC) and attended by 44 participants from 14 countries, with 2 participants connecting remotely. Notably, from the standpoint of democratizing and innovating scientific meeting design, an SCD patient advocate also presented at the workshop, giving a broader real-life perspective on patients' aspirations, needs, and challenges. A major component of the workshop was new approaches to harness SCDO to harmonize data elements used by different studies. This was facilitated by a web-based platform onto which participants uploaded data elements from previous or ongoing SCD-relevant research studies before the workshop, making multisite collaborative research studies based on existing SCD data possible, including multisite cohort, SCD global clinical trials, and SCD community engagement approaches. Trainees presented proposals for systematic literature reviews in key SCD research areas. This expert review emphasizes potential and prospects of SCDO-enabled data standards and harmonization to facilitate large-scale global SCD collaborative initiatives. As the fields of public and global health continue to broaden toward planetary health, the SCDO is well poised to play a prominent role to decipher SCD pathophysiology further, and co-design diagnostics and therapeutics innovation in the field.

Abstract
OBJECTIVES The association between psychosocial stressors (PS) and chronic kidney disease (CKD) among sub-Saharan African (SSA) populations is unknown. We examined the association between PS and CKD prevalence among rural and urban Ghanaians and Ghanaian migrants living in three European cities. We also assessed if the influence of PS on CKD is partially mediated by primary risk factors (hypertension and diabetes) of CKD. DESIGN A multi-centred cross sectional data from the Research on Obesity and Diabetes among African Migrants study. SETTING Rural and urban Ghana and three European cities (Amsterdam, Berlin and London). PARTICIPANTS A random sample of 5659 adults (Europe 3167, rural Ghana 1043 and urban Ghana 1449) aged 25-70 years. EXPLANATORY MEASURES PS defined by negative life events, perceived discrimination, perceived stress at work/home and depressive symptoms. Three CKD outcomes were considered using the 2012 Kidney Disease: Improving Global Outcomes severity of CKD classification. Comparisons between PS and CKD outcomes were made using logistic regression analyses across all sites. RESULTS We observed higher proportion of negative life events (68.7%) and perceived permanent stress (15.9%) among Ghanaians living in Ghana than Ghanaians living in Europe. Depressive symptoms (7.5%) and perceived discrimination (29.7%) were more common among Ghanaians living in Europe than Ghanaians living in Ghana. No significant association was observed between any of the PS constructs and CKD outcomes across sites except for positive association between stress at work/home and albuminuria (2.81, 95% CI 1.46 to 5.40) and CKD risk (2.78, 95% CI 1.43 to 5.43) among Ghanaians living in Berlin. CONCLUSION Our study found a positive association between stress at work/home and albuminuria and CKD risk. There was no convincing evidence of associations between the other PS constructs and the prevalence of CKD risk. Further studies are needed to identify potential factors driving the high prevalence of CKD among these populations.

Abstract
Introduction There is limited data on the prevalence of thyroid dysfunction in Ghanaian individuals with chronic kidney disease (CKD). Studies exploring the effect of thyroid hormones on renal function decline are also scanty. Unrecognized thyroid dysfunction in CKD may increase the burden of adverse health outcomes. The aim of this study was to determine thyroid hormone status and lipid profiles in patients with CKD attending the Renal Unit of the Korle-Bu Teaching Hospital. Methods 60 clinically euthyroid patients with CKD, and 65 clinically euthyroid subjects without CKD were recruited for this study. Estimation of effective glomerular filtration rate (eGFR) was done using the 4-variable Modification of Diet in Renal Disease (MDRD) formula with subsequent staging of CKD (stages 2-4). Collected venous blood samples from all study participants were analyzed for creatinine, free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH), total cholesterol (TC), high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) and triglycerides (TG). Results Levels of TC, HDL, LDL, and TSH levels did not differ significantly between the two study groups. However, TG, VLDL, FT3 and FT4 levels were significantly higher in CKD patients than in the control group. TC, TG, HDL, LDL, VLDL and TSH levels were not significantly different between stages of CKD in study subjects, although FT4 and FT3 levels were significantly different between all stages of CKD. Conclusion Higher levels of FT3 and FT4 but not TSH, are associated with the incidence of CKD and eGFR decline in Ghanaian CKD patients.

Abstract
An inter-comparison study was conducted to assess the capability of dosimetry systems of individual monitoring services (IMSs) in Gabon and Ghana to measure personal dose equivalent Hp(10) in photon fields. The performance indicators assessed were the lower limit of detection, linearity and uncertainty in measurement. Monthly and quarterly recording levels were proposed with corresponding values of 0.08 and 0.025 mSv, and 0.05 and 0.15 mSv for the TLD and OSL systems, respectively. The linearity dependence of the dosimetry systems was performed following the requirement given in the Standard IEC 62387 of the International Electrotechnical Commission (IEC). The results obtained for the two systems were satisfactory. The procedure followed for the uncertainty assessment is the one given in the IEC technical report TR62461. The maximum relative overall uncertainties, in absolute value, expressed in terms of Hp(10), for the TL dosimetry system Harshaw 6600, are 44. 35% for true doses below 0.40 mSv and 36.33% for true doses ≥0.40 mSv. For the OSL dosimetry system microStar, the maximum relative overall uncertainties, in absolute value, are 52.17% for true doses below 0.40 mSv and 37.43% for true doses ≥0.40 mSv. These results are in good agreement with the requirements for accuracy of the International Commission on Radiological protection. When expressing the uncertainties in terms of response, comparison with the IAEA requirements for overall accuracy showed that the uncertainty results were also acceptable. The values of Hp(10) directly measured by the two dosimetry systems showed a significant underestimation for the Harshaw 6600 system, and a slight overestimation for the microStar system. After correction for linearity of the measured doses, the two dosimetry systems gave better and comparable results.

Abstract
Introduction Knowledge of hepatitis B virus (HBV) genotype is an important predictive variable which might have an impact in management and treatment of patients with chronic hepatitis B infection. In Ghana very little information is available on hepatitis B genotypes. This study was conducted to determine the distribution of HBV genotypes circulating among chronic hepatitis B patients reporting at the Korle-Bu Teaching Hospital (KBTH), Accra, Ghana. Methods Blood samples (10 ml) were collected from 250 consenting patients. DNA was extracted and amplified using polymerase chain reaction technique. Restriction fragment length polymorphism (RFLP) was used for the detection of genotypes. Results Out of the 250 chronic hepatitis B patients who were HBsAg positive, 91 (36.4%) were males aged 29.8 ± 9.1 and 159 (63.6%) females aged 33± 12.1 years. HBV DNA was detected in 111 (44.4%) but only 58 (52%) of these were typeable. These were classified as genotype A, 8 (7.2%); genotype D, 3 (2.7%) and genotype E, 47 (42.3%). Our results did not show any association between the infecting genotype and age (X2= 0.923; p-value=0.623) or gender (X2= 0.283, p= 0.579). Conclusion Consistent with similar studies worldwide, the results suggest that genotypes A, D and E were the genotypes circulating among chronic hepatitis B patients who reported to the Korle-Bu Teaching Hospital with genotype E being the most predominant and therefore constitutes an important public health concern. We recommend further epidemiological studies to understand the implication of genotype E in terms of disease progression and treatment.

Abstract
INTRODUCTION Though giardiasis is an important public health problem in Ghana, several aspects of its epidemiology, particularly the molecular epidemiology has not been investigated adequately. This could be a major hindrance to effective surveillance and control of giardiasis in the country. The study was carried out to determine the prevalence, risk factors and genotypes of Giardia lamblia infecting children at a paediatric hospital in Ghana. METHODS A total of 485 patients including 365 diarrhoea and 120 non-diarrhoea children were enrolled into the study. Stool samples were collected and analysed for parasite presence using microscopy, ELISA and PCR. Positive samples were subsequently characterized into assemblages by PCR-RFLP, and further confirmed with sequencing of the glutamate dehydrogenase (gdh) gene. Epidemiological data on demographic, clinical and behavioral features of the study subjects were also collected. RESULTS Prevalence of G. lamblia infections in diarrhoea and non-diarrhoea children were 5.8% and 5% respectively (P>0.5). Sequence data confirmed Giardia lamblia assemblage B as the predominant genotype in both diarrhoea and non-diarrhoea cases. There was no significant association of G. lamblia infection with any of the epidemiological variables investigated. CONCLUSION Our findings suggest that assemblage B could be the predominant genotype causing giardiasis in children. Increased public health education focusing on good sanitary practices, particularly among mothers and children, could decrease the risk of G. lamblia infection.

Abstract
Introduction Pregnancy during the adolescent period is challenging mainly because of the nutritional demands of both the adolescent and pregnancy period. The risk for anaemia increases especially in developing countries such as Ghana where malaria is endemic and the practice of pica is common. In this study, we sought to determine the prevalence of anaemia, pica practice and malaria infection among pregnant adolescent girls and assess the extent to which these factors are associated. Methods Two hundred and sixty five (265) pregnant adolescent girls were recruited from three hospitals in Accra. Haemoglobin levels, malaria infection and the practice of pica were assessed. Pearson's Chi squared tests were used to determine associations and logistic regression analysis was used to determine the odds of being anaemic. Significance was set at p≤0.05. Results Anaemia prevalence was 76% with severity ranging from mild (47.8%) to severe (0.8%). About 27.5% were moderately anaemic. Pica was practiced in only 9.1% of the girls. Malaria infection was prevalent in 17.7% of the girls. The logistic regression analysis indicated that pregnant girls with malaria infection were 3.56 times more likely to be anaemic when compared to those without malaria. Also, those who practiced pica were 1.23 times more likely to be anaemic when compared to those who did not practice pica. Conclusion Anaemia is very prevalent in pregnant adolescent girls and is a public health problem. Drastic measures should be taken to reduce the high prevalence.

Abstract
Background Uterine fibroids are the most common benign tumours affecting premenopausal women and are often associated with considerable hospitalization and morbidity. Literature shows virtually no study concerning the quantification of the main factors associated with uterine fibroids in Ghanaian women. The purpose of this study was to assess the main factors associated with uterine fibroid among Ghanaian women presenting for ultrasound. Method A prospective cross-sectional study design was employed in this study. A total of two hundred and forty-four (244) women were consecutively evaluated from November 2011 to February 2012 using a 2–5 MHz curvilinear probe of Philips HD3 ultrasound machines at three centres in Accra using a trans-abdominal pelvic approach. Data was analysed with (SPSS) version 20.0 for windows, 2010; Chicago. The Pearson’s Chi-square test was used to determine associations between selected demographic and gynaecological characteristics and uterine fibroid appearance. All tests were two-tailed and p-value of less than 0.05 was interpreted as significant. Results The range, mean and standard deviation (SD) of the patients’ age were 14–54 years, 31.89 years and ± 7.92 respectively. Factors that associated significantly with uterine fibroid in Ghanaian women included obesity (X2 = 17.3, p-value = 0.001), participant’s age range (X2 = 47.4, p-value = 0.001), parity (X2 = −10.169, p-value = 0.001), and age at last delivery (X2 = 34.579, p-value = 0.001). Conclusion Uterine fibroid was mainly associated with women of older age group of the reproductive age than the younger age categories and also associated more with women with without children compared to those with more children. Moreover, it associated more with obese patients and patient with late age at last delivery.

Abstract
Background Sickle cell trait (SCT) or Hemoglobin S (HbS) trait which is due to inheritance of an abnormal hemoglobin (Hb) gene from one parent and a normal gene from the other has been known to be common among people of African descent. Individuals with SCT may find themselves in the blood donor population without knowing their ‘carrier’ status and this may have severe consequences on their health as well as that of a recipient, particularly if they happen to be a sickle cell disease patient. The aim of the study was to determine the prevalence of HbS trait among blood donors. Results This cross-sectional study employed convenience sampling method to recruit subjects. A total of 150 prospective and healthy blood donors comprising 138 males and 12 females were involved in the study. Two (2) ml of venous blood was collected from each donor into K3EDTA tubes and analyzed using the sodium metabisulphite slide test and cellulose acetate Hb electrophoresis at alkaline pH (8.6) for Hb genotypes. Statistical Package for Social Sciences version 20.0 (SPSS 20.0) and Chi square were used to analyse the data obtained. Out of the 150 blood donors, 133 (88.7 %) tested negative for sickling (131 were genotype AA and 2 were AC) and 17 (11.3 %) tested positive for sickling, all of whom were genotype AS. Conclusion The results of the study showed the existence of SCT among the blood donor population sampled. Taking blood from such people can harm their health as well as that of the recipient if they happen to be sickle cell disease (SCD) patients. It is therefore recommended that blood donors as well as donated blood units should be screened for SCT to avoid causing any harm to both the donor and recipient.

Abstract
BACKGROUND Assessment of impairment and disability measures on dynamic balance status of elderly patients is well documented in the rehabilitation of neuromuscular disorders. Few studies however considered similar evaluation in musculoskeletal disorders. OBJECTIVE To determine the influence of pain, hip range of motion and level of activity on dynamic balance among elderly people with hip osteoarthritis (OA). METHODS Elderly patients with hip OA participated in the cross-sectional survey. The impairment measures were assessed using the visual analogue scale and double-arm universal goniometer whilst their levels of activity were assessed with the Barthel Index. Participants performed Turn-180 on two trials by taking steps clockwise and anti-clockwise round a sturdy arm chair. The total number of steps taken to complete each Turn- 180 was determined. Descriptive statistics were used to summarize data whilst Pearson moment correlation coefficient determined the correlations of the variables at 95% confidence interval. RESULTS The study involved 87 participants comprising 40(46%) males and 47(54%) females. The age of the participants ranged from 60 to 74 years with a mean of 65.8±4.5 years. There was a positive and significant correlation (r=0.596; p<0.001) between the participants' pain and steps taken to complete Turn-180. The participants' hip flexibility and the level of activity were also significantly and inversely correlated with the performance of Turn-180. CONCLUSION The dynamic balance of the sampled elderly patients was considerably influenced by pain, hip flexibility and level of activity, thereby putting premium on the assessment of the variables during musculoskeletal rehabilitation of elderly patients.

Abstract
Background Persistent hyperglycaemia is a hallmark of Diabetes Mellitus (DM). It causes increased production of free radicals, especially reactive oxygen species (ROS), — resulting in oxidative stress. Reactive Oxygen Species have been implicated in the development of haematological complications in patients with diabetes. Superoxide Dismutase (SOD) is one of the most effective antioxidant enzyme defense systems against free radicals. Methods From February through May 2014, we assessed the relationship between oxidative stress and haematological profiles among individuals with and without diabetes. A cross sectional study of 66 case patients and 44 age-matched controls were recruited from the National Diabetes Management and Research Centre (NDMRC), Korle-Bu Teaching Hospital, Accra, Ghana. Blood samples were obtained from study participants with consent. We determined the haematological profiles of study participants and measured their oxidative stress levels using a standardized kit for SOD activity. Results Higher white blood cell (WBC) counts were seen in the diabetes cohort (p-value = 0.023). The SOD activity tended to be lower in diabetes patients (p–value = 0.144 however) while higher neutrophil levels seemed to correlate with SOD activity (R = 0.249; R2 = 6.2 %; p-value = 0.049). There did not appear to be a correlation between fasting blood glucose (FBG) and SOD activity (R = −0.044; p-value = 0.727). Conclusion The study reports similar oxidative stress levels, as measured by SOD activity, in diabetic and non-diabetic adults. The SOD activity did not appear to correlate with FBG and several other haematological parameters. Further study would be required to investigate the relationship between these haematological indices and diabetic micro- and macro-vascular complications in our population.

Abstract
BACKGROUND Information technology has potential to improve health care delivery particularly among individuals with chronic diseases such as diabetes in low and middle-income countries (LMIC). Research on the usefulness of information technology to manage persons living with chronic diseases is scarce in LMIC. We sought to evaluate the effect of an electronic reminder system on cardiovascular risk factors (blood pressure, heart rate, and fasting plasma glucose) and adherence to clinical appointments among persons living with diabetes. RESEARCH DESIGN AND METHODS A randomized controlled design was used to recruit 200 diabetic patients (intervention n=100, control n=100) from the National Diabetes Management Research Centre, Accra. All patients received usual diabetes care. The intervention group was given electronic reminders for their clinical appointments and their physicians were prompted with abnormal laboratory results for six months. RESULTS Baseline characteristics were largely similar for both groups. At six months follow up, the mean reductions of all the cardiovascular risk factors in the intervention group were significantly greater than in the control group: -1.7 kg/m(2) versus -1.1 kg/m(2)(p=0.002) for BMI; -4.7 mmHg versus -2.8 mmHg (p=0.002) for SBP; -5.3 mmH versus -3.1 mmHg (p=0.001) for DBP; -1.7 bpm versus -0.1 bpm (p=0.001) for heart rate and -2.3 mmol/L versus -1.6 mmol/L (p=0.001) for fasting plasma glucose, respectively. Adherence to appointment schedules was also significantly higher in the intervention group compared with the control group (97.8% versus 89.4%, p=0.010). CONCLUSIONS Locally developed electronic initiatives such as this resulted in improved cardiovascular risk factors and effective compliance to clinical practices and improved quality of care for persons living with diabetes.

Abstract
Infertility among couples is a sensitive issue in Ghana; females are mostly blamed. Most male infertility cases are generally due to low sperm counts (oligozoospermia), poor sperm quality - characterised by poor sperm motility (asthenozoospermia) - or a combination of both (oligoasthenozoospermia). This is a retrospective study from January 1995 to December 2005 which determined the level and type of male infertility in and around the city of Tema. Seminal fluid analysis reports of male clients who visited the Adom Medical Laboratory in Tema were extracted from laboratory data and analysed. Our study involved 2795 males in the age range of 24-36 years. In 1995, 75% of the total samples analysed had sperm concentrations ranging from 21 to 350 million sperms/ml and showed a decreasing trend to 41% in 2005. Samples with sperm concentrations below 20 million sperms/ml in 1995 increased from 20.5% to 57.6% in 2005; those with active motility > 45% decreased from 27 (30.7%) in 1995 to zero (0%) in 2005, whilst samples with > 50% non-motile sperms increased from 47 (53.4%) in 1995 to 449 (87.7%) in 2005. Male infertility in the samples analysed was due to a combination of oligozoospermia and asthenozoospermia.

Abstract
Malaria is hyper-endemic in Ghana. Haematological alterations in the disease pathology may offer complimentary criteria to improve clinical and microscopy diagnosis. Our primary outcome was to evaluate haematological parameters in children with Plasmodium falciparum infections and report their predictive risk and diagnostic performance for malaria infections in Ghana. Haematological data, including thin and thick blood films were examined for children less than 12 years of age in a multicenter-based active case finding approach. Haematological changes were common in P. falciparum infected children and more pronounced in severe malaria cases. More so, a unit increase in parasiteamia increased the odds for severe malaria infection by 93 % [OR, 95 % CI: 1.93 (1.28-2.91); P value = 0.02]. In multivariate regression, low haemoglobin was a significant haematological change in predicting P. falciparum infections [OR, 95 % CI: 3.20 (1.26-7.09); P value = 0.001]. Low haemoglobin levels <11 g/dl was the most reliable indicator for P. falciparum infections [with a sensitivity of (64 %), specificity (71 %), positive predictive value (83 %) and likelihood ratio (2.2)]-even when evaluated in combination with leucocytosis, lymphocytopaenia and high neutrophil counts >7,500 µL. In malaria endemic settings, low haemoglobin concentration (<11 g/dl) in children with febrile illness should prompt a more diligent search for the malarial parasite to limit the misuse and abuse of anti-malarial drugs.

Abstract
BACKGROUND Hepatitis D virus (HDV), a defective RNA virus which depends on hepatitis B virus (HBV) for its replication and expression, appears to be highly pathogenic and modifies the natural history of HBV infection. Two types of infection, co-infection and super-infection are recognised. During infection, anti-delta antibodies appear in serum and can be detected by Enzyme linked Immunosorbent Assay (ELISA). OBJECTIVE We determined the prevalence of hepatitis D infection amongst HBsAg-positive patients with HBV-related liver diseases in Accra, Ghana using an Enzyme linked Immunosorbent assay (ELISA) method. METHODS We collected blood samples from 53 patients with hepatitis B-related liver diseases. The sera were analysed using a commercially available kit, the EIA-ANTI-HDV, a third generation ELISA kit (Globe Diagnostics, Italy). RESULTS There were 39 males (73.6%) and 14 females (26.4%) giving a male:female ratio of about 3:1.The mean age of patients was 38.6 years (range, 15-75). Six patients were reactive for anti-delta antibodies, yielding a HDV sero-prevalence of 11.3%. A higher proportion of males were anti-HDV positive (9.4%) compared to females (1.9%) but the difference was not statistically significant (p=0.350). Anti-HDV was detected in 4(22.2%) patients with chronic hepatitis B, 1(7.6%) with cirrhosis of the liver and 1(5.3%) with hepatocellular carcinoma. CONCLUSION The prevalence of HDV infection amongst patients with liver disease in Accra with HBV-related liver diseases appears to be high compared to developed countries but similar to several developing countries. No significant difference exists in gender prevalences. A concerted public health effort is required to reduce this high prevalence rate.

Abstract
BACKGROUND Stroke is often characterized by disturbance in balance and mobility among the survivors with its attendant rehabilitation potentials. Static balance serves as a foundation for attainment of functions in patients with stroke, yet its determinants are usually under-estimated. AIM This study was therefore designed to determine the influence of some clinical and demographic factors on static balance in stroke survivors. MATERIAL AND METHODS Eighty (80) hemiparetic stroke survivors participated in this cross-sectional survey. Demographic variables include age, height, weight and body mass index (BMI) whilst knee range of motion, (ROM) duration of stroke, levels of disability and spasticity of the paretic lower limbs of the participants were the clinical variables. Universal Goniometer, Barthel Index, and Modified Ashworth Scale were used to assess ROM, disability and spasticity levels respectively. The outcome measure for static balance was Functional Reach Test. Pearson's correlation coefficient analysis was performed to establish the correlations between some selected variables and the static balance. Level of significance was set at p<0.05. RESULTS The mean age of the participants was 56.7+/-12.8 years. They comprised 37(46.2%) right hemiparetic and 43 (53.8%) left hemiparetic patients. Significant positive correlation was observed between functional reach scores and knee ROM, spasticity and disability levels (r=0.3; r=0.5; 0.2) respectively. However, the mean age, weight, height and BMI of the participants were not significantly correlated with functional reach scores. CONCLUSION Joint range of motion, spasticity and disability levels were the main determinants of static balance in stroke survivors. These factors should be considered whilst priotizing goals during rehabilitation of stroke survivors.

Abstract
A radiofrequency (RF) electromagnetic radiation safety survey had been carried out at public access points in 46 towns with 76 Global Systems for Mobile communication cell sites in two major cities in Ghana. The objective was to determine the levels of RF field in residential areas, schools and market places, and compare the measured results with the guidelines set by the International Commission of Non-Ionising Radiation (ICNIRP). Measurements were made with log-periodic antenna coupled with spectrum analyzer. The results varied from 0.85 to 1.07 mW m(-2) and 0.78 to 1.19 mW m(-2) for the transmission frequencies of 900 and 1800 MHz, respectively. The result generally shows a compliance with the ICNIRP limit of 0.024 % but was 108 times higher than a similar survey carried out in Ghana 2 y ago.

Abstract
AIM OF THE STUDY Croton membranaceus root and leaf extracts are used in the Bahamas to aromatize tobacco, in Nigeria to improve digestion, and in Ghana, for benign prostate hyperplasia. Despite claims of success there is paucity of information on its toxicity. The aim of this study was to determine if Croton membranaceus has acute toxicity properties. MATERIALS AND METHODS Roots were air-dried in a solar dryer for one week before milling. The powder was extracted with 96% ethanol, freeze-dried and re-extracted with distilled water and freeze-dried. 15 male Sprague-Dawley rats (180-200 g) were divided equally into 2 treatment groups [low dose (LD) and high dose (HD)], plus a control group (C). LD and HD received 1500 and 3000 mg/kg b.wt. Croton membranaceus aqueous extract, respectively, one time and observed for 14 days. Haematological [Full Blood Count and haemoglobin (Hb)], biochemical [bilirubin, alanine aminotransferase (ALA), aspartate aminotransferase (AST), total protein, albumin, globulin, alkaline phosphatise (ALP), γ-glutamyltranspetidase (GGT), urea, creatinine, creatinine kinase - Muscle and Brain (CK-MB), creatinine kinase - Total (CK-R)] examinations were performed. RESULTS Control group's CK-MB (5444±534 U/L) and LD group CK-MB (4014±1016 U/L) were significantly different (p<0.05). Control and the HD group CK-MB (3955±1135 U/L) were significantly different (p<0.05). Both LD and HD CK-R levels (697±197U/L and 732±203 U/L, respectively), were lower than the control (1139±220 U/L) at 48 h and 14 days (p<0.05, p<0.05, respectively). γ-GT levels of the HD group was 4.8±0.4 U/L compared to the Control group value of 0.9±0.2 U/L (p<0.05). CONCLUSIONS Taking all factors into consideration, Croton membranaceus ingestion does not produce general acute toxicity. However, its creatinine kinase lowering ability could be explored.
