Abstract
Diarrhoea, which is a clinical manifestation of various illnesses, is frequently observed in dogs. Regrettably, many dog owners find it difficult to provide comprehensive case histories, primarily because of limited interaction with their canine companions. This study aimed to evaluate the potential of faecal biochemical analytes in detecting and characterizing acute diarrhoea in dogs. Sixty-two domestic dogs were selected using the proportionate stratified sample technique. A structured questionnaire was used to collect demographic and clinical data. Faecal stool specimens from the dogs were obtained using the colon flush technique. The specimens were taken through biochemical analysis to determine urea, creatinine, total bilirubin, total cholesterol, triglycerides, gamma-glutamyl transferase and uric acid levels. Results showed a significant association between the diarrhoea status of the participants and their age, weight, breed, body size, source of last diet, period of inappetence, and other gastrointestinal signs (p < 0.050, respectively). Dogs that had not eaten in at least three days were five times more likely (p < 0.05) to have diarrhoea. Furthermore, miniature breeds were about six times more likely to develop diarrhoea (p < 0.05). Of the seven selected biochemical parameters, total faecal cholesterol was the most predictive index in diagnosing acute diarrhoea in dogs, with a likelihood ratio of 6.5, and it was the most accurate in predicting defecation stooling frequency and texture. In summary, in situations of inadequate case histories, measuring total faecal cholesterol could assist veterinarians in detecting diarrhoea and predicting its faecal stooling texture and frequency in dogs.

Abstract
INTRODUCTION Uterine artery (UtA) Doppler sonography is a potential screening tool for pregnancy complications in placental insufficiency. Evaluation of the maternal and fetal vessels in pregnancy ensures accurate identification and prediction of pregnancy complications, such as preeclampsia (PE) and intrauterine growth restrictions (IUGR). The study aims to establish local reference values for UtA in a Nigerian population. METHODS This prospective longitudinal study was conducted among 230 pregnant women. All participants had their left (Lt) and right (RT) UtAs evaluated with a Doppler ultrasound from 11 to 30 weeks 6 days of gestational age. Peak systolic velocity (PSV), End diastolic Velocity (EDV), Systolic/Diastolic ratio (S/D), Pulsatility Index (PI), and Resistivity Index (RI) were measured and documented. RESULTS The mean values of UtA at 11-30 weeks 6 days of GA ranged as follows: 0.79-0.53 (RI), 1.83-0.79 (PI), 5.16-2.23 (S/D), 96.37-98.00 (PSV) & 26.07-44.14 (EDV). While the mean values of the Rt. & Lt. UtA 's ranged as follows: 0.79-0.50 (RI. Rt), 0.78-0.56 (RI. Lt), 2.05-0.80 (PI. Rt), 1.61-0.78 (PI. Lt), 6.03-2.13 (S/D. Rt), 4.29-2.33 (S/D. Lt), 89.79-99.23 (PSV. Rt), 102.76-96.71 (PSV. Lt) & 23.31-45.25 (EDV. Rt), 28.83-43.02 (EDV. Lt) respectively. CONCLUSION UtA Doppler reference range was established in the study population. These reference ranges will be of clinical value in daily obstetric practice. IMPLICATION FOR PRACTICE Obstetricians and sonographers will apply these values for early prediction of pregnancies at risk of complications in the locality.

Abstract
INTRODUCTION Radiology equipment requires routine maintenance to prevent equipment breakdown. Equipment breakdown can lead to adverse patient outcomes and lost revenue to hospitals. In Ghana, there is a mismatch between the available radiology equipment and requests which may result in frequent breakdown. Several studies have been conducted to investigate equipment downtime across radiology departments. However, there is none for Ghana. This study therefore investigated the downtimes of radiology equipment across three hospitals in Ghana. METHOD The study covered the period January-December 2020. An inventory sheet was used to collect data on equipment specifications, frequency of breakdown, downtimes, average daily patient throughput, the average cost of common examinations, the availability of post-installation training and maintenance contracts/agreements. RESULTS The study reviewed 32 items of radiology equipment. Radiology equipment across the hospitals broke down frequently and downtimes were very high. Radiographers/radiologists across the hospitals were provided with poor/inadequate post-installation training, and maintenance contracts/agreements were unavailable. The radiology equipment downtimes resulted in significant lost revenue of GH₵ 16,279,803 (US$ 1,968,537). CONCLUSION Radiology equipment across the hospitals broke down frequently and downtimes were lengthy leading to significant lost revenue for the hospitals. Post-installation trainings were poor/inadequate, spanning a few hours. Also, maintenance contracts/agreements were non-existent across the three hospitals. A nationwide study is needed to determine equipment downtimes and lost revenue across all radiology departments in Ghanaian hospitals, to better inform policy-making. IMPLICATIONS FOR PRACTICE This study may help hospital managers and other stakeholders involved in policy formulation and strategic planning, put measures in place to minimise radiology equipment breakdown in Ghana. The study may also help optimise radiology services and enable radiology departments to render uninterrupted clinical services to patients in Ghana.

Abstract
INTRODUCTION Insulin resistance (IR) is one of the common chronic metabolic disorders in Africa and elsewhere. Accumulation of lipids in the body may be due to an imbalance in the metabolism of lipids, glucose and proteins. Ceramides are a sphingolipid class of lipids that are biologically active and vital in the production of more complex lipids. Circulating ceramides are thought to have a role in the development of obesity-related IR, although the precise involvement remains unclear. AIM To investigate the impact of circulating ceramide on IR and body adiposity in people with and without type 2 diabetes mellitus (T2DM). METHODOLOGY The study was observational and cross-sectional. There were a total of 84 volunteers with T2DM and 75 nondiabetics (control). The participants' ages, body mass indexes (BMI), waist circumferences, and blood pressure (BP) were among the clinical parameters assessed. Ceramide levels, fasting plasma glucose (FPG), lipids, basal insulin levels and glycated haemoglobin (HbA1c) were also measured. Additionally, the homeostatic model assessment for IR (HOMA-IR) and beta cell function (HOMA-β) were computed. RESULTS T2DM and control participants had different mean values for anthropometric parameters, BP, FPG, HbA1c, lipids, insulin, HOMA-IR, HOMA-β and ceramide levels (p < .05 for all). HOMA-IR, HOMA-β and cardiovascular risk were significant correlates with ceramide levels in the T2DM group (r = 0.24; -0.34; 0.24, p < .05, respectively). Further, FPG (OR = 1.83, p = .01) and ceramide (OR = 1.05, p = .01) levels were significant predictors of IR in the case group. CONCLUSION Patients with T2DM exhibited high ceramide concentrations, which, when combined with high FPG, were associated with IR. The consequences of circulating ceramides in health and disease; however, merit further research.

Abstract
Background and Aim Adipocytes secrete a peptide hormone called leptin, which plays a crucial role in controlling appetite and energy expenditure. Alterations in leptin concentrations are associated with CKD-related cardiovascular problems such as hypertensive heart disease (HHD). Despite the link, data on the precise function of leptin in people with CKD and HHD is scant. Methods An observational cross-sectional study involving a total of 108 participants (72 CKD patients with HHD and 36 healthy controls). Their demographic and anthropometric information was collected using a standardized questionnaire. Certain clinical measures such as blood pressure and body mass index (BMI) were assessed. Fasting blood samples were analyzed for levels of plasma glucose (FPG), lipids, creatinine, and leptin. Data were analyzed with SPSS v23. Results Leptin, FPG, creatinine and triglyceride levels were all significantly higher in CKD patients with HHD compared to controls (p < 0.01 for all). Furthermore, advanced CKD status (being in stage 5), having a 6-year diagnosis of HHD, being female, having a higher BMI, and elevation in levels of HDL and FPG contributed significantly to the variance in serum leptin levels in the case group (β = 0.37, 0.22, 0.19, 0.18, 0.27, 0.28; p < 0.05 for all). In the control group, the female gender had the biggest unique effect on circulating leptin levels, followed by BMI and eGFR (β = 0.71, 0.34, -0.22; p < 0.01 for all). Conclusion Patients with CKD who also had HHD reported considerably higher circulating leptin levels. Significantly higher blood leptin levels were shown to be associated with CKD stage 5 in the case group. These results are consistent with the role of leptin in the metabolic complexity seen in CKD patients. There needs to be more research into treatments that aim to lower leptin levels in CKD patients with HHD.

Abstract
OBJECTIVE Perilipin A is a common protein that coats lipid surfaces preventing them from being exposed to oxidative damage. Researchers have found little consistency in the relationship between perilipin A levels in the blood and body fat. This study was a cross-sectional observational that looked at circulating perilipin A levels and how they relate to metabolic health. RESULTS The participants in this study were 86 individuals with a mean age of 45.5 ± 1.2 years. Multiple clinical and metabolic indicators (age, weight, BMI, total body fat mass, triglyceride, and HOMA-IR) were shown to be inversely associated with perilipin A levels (rho = - 0.32, - 0.37, - 0.40, - 0.45, - 0.33 and - 0.29; p < 0.05 respectively). Obese persons were almost six times more likely than non-obese individuals to have lower perilipin A levels (odds ratio = 6.22, CI = 2.35-11.50, p < 0.001). Our findings underscore the important role of perilipin A proteins in metabolic health.

Abstract
INTRODUCTION Diagnostic Reference Levels (DRLs) are essential for optimisation in mammography. A local DRL for screen-film mammography has been established in Ghana but none exists for the digital mammography systems. Furthermore, technological advancement is phasing out the use of screen-film mammography and replacing it with digital mammography systems. This study aims to establish the local DRLs used in digital mammography across three institutions in Ghana to guide mammography practice. METHODS Average glandular dose (AGD), compressed breast thickness (CBT), age of patients, entrance surface exposure (ESE), kVp, and mAs were retrospectively extracted from three digital mammography systems. The 75th and 95th percentile values were obtained for the AGD of each mammography projection and at CBT of 60 ± 5 mm. The correlation between the AGD and CBT, kVp, mAs, and ESE were investigated. RESULTS The 75th percentile for the AGD at CBT of 60 ± 5 mm for Centres 1, 2, 3, and all centres were 2.3, 1.8, 2.1, and 2.0 mGy respectively. The DRLs obtained were comparably higher than international studies except those of the United Kingdom. The AGD showed a strong positive correlation with the CBT, kVp, mAs, and ESE. There was variability in the AGD applied across the three centres for the craniocaudal (CC) and mediolateral oblique (MLO) projections. The mean AGD, mAs, and ESE for all the three centres and per centre recorded were higher than previous studies, but the mean kVp and CBT were lower than previous studies. CONCLUSION The higher DRLs estimated in this preliminary study indicates that there is a need for dose optimisation in digital mammography practice in Ghana to improve radiation protection. IMPLICATIONS FOR PRACTICE The findings will guide the process of optimisation and limit the variations in the radiation dose during mammography practice.

Abstract
INTRODUCTION Breast compression during mammographic examinations improves image quality and patient management. Several studies have been conducted to assess compression force variability among practitioners in order to establish compression guidelines. However, no such study has been conducted in Ghana. This study aims to investigate the compression force variability in mammography in Ghana. METHODS This retrospective study used data gathered from 1071 screening and diagnostic mammography patients from January, 2018-December, 2019. Data were gathered by seven radiographers at three centers. Compression force, breast thickness and practitioners' years of work experience were recorded. Compression force variability among practitioners and the correlation between compression force and breast thickness were investigated. RESULTS Mean compression force values recorded for craniocaudal (CC) (17.2 daN) and mediolateral oblique (MLO) (18.2 daN), were within the recommended values used by western countries. Most of the mammograms performed - 80% - were within the National Health Service Breast Screening Programme (NHSBSP) range. However, 65% were above the Norwegian Breast Cancer Screening Programme (NBCSP) range. Compression forces varied significantly (p = 0.0001) among practitioners. Compression forces increased significantly (p = 0.0001) with the years of work experience. A weak negative correlation (r = -0.144) and a weak positive correlation (r = 0.142) were established between compression force and breast thickness for CC and MLO projections respectively. CONCLUSION This initial study confirmed that although wide variations in compression force exist among practitioners in Ghana, most practitioners used compression forces broadly within the range set by the NHSBSP. As no national guidelines for compression force currently exist in Ghana, provision of these may help to reduce the range of variations recorded. IMPLICATIONS FOR PRACTICE Confirmation of variations in compression will guide future practice to minimize image quality disparities and improve quality of care.

Abstract
Background and aim There is a growing need to develop new drugs for type II diabetes mellitus (DM) from plant sources due to the high cost and adverse side effects of current drug therapies. To this end, the antidiabetic activity of aqueous stem-bark extract of A. polycarpa (APE) in alloxan-induced diabetic ICR mice was investigated. Experimental procedure The effect of APE (20, 100 and 500 mg/kg), glibenclamide and metformin as positive controls, were determined over 4 weeks on fasting blood glucose (FBG). An oral glucose tolerance test (OGTT) was also conducted. The effects of these treatments on the morphology of the pancreas were assessed. In addition, phytochemical constituents and antioxidant properties of APE were determined. Results and conclusion APE, like glibenclamide and metformin, showed significant hypoglycaemic effect. The OGTT supported the hypoglycaemic effect. The destroyed pancreatic beta-cells in diabetic control mice were restored to normal by APE or drug treatment. APE showed antioxidant activity by scavenging DPPH free radicals; this may be due to the presence of phenolic compounds, particularly flavonoids. Thus, APE may act by restoring pancreatic beta-cell integrity through mopping of reactive oxygen species (ROS) associated with the diabetic state, and thereby improving pancreatic function and consequently, the lowering of FBG levels. These findings provide ample evidence to validate the traditional use of A. polycarpa in the management of DM. Aqueous stem bark extract of A. polycarpa (APE) possesses significant antidiabetic activity. APE has the ability to cause the regeneration of beta cells of the pancreas. APE’s possess antioxidant activity and may scavenge ROS, thus help in overcoming advanced complications of DM. Alkaloids and phenolics (flavonoids) detected may be responsible for the hypoglycaemic and antioxidant activity of APE.

Abstract
OBJECTIVE Research findings on the relationship between serum androgens and adipose tissue in older females are inconsistent. We aimed to clarify the relationship using state-of-the-art techniques to evaluate associations between body fat distribution and plasma testosterone (T) levels in older postmenopausal women. DESIGN Observational, cross-sectional study of healthy, community dwelling postmenopausal women. PATIENTS AND MEASUREMENTS Postmenopausal women (60-80 years old) were included in this study. Overall body composition was evaluated by dual-energy X-ray absorptiometry. Abdominal and thigh fat depots were measured by magnetic resonance imaging. Circulating T concentrations were analysed by liquid chromatography-tandem mass spectrometry. RESULTS Thirty-five women (66.6 ± 0.8 years) participated in this study. T levels were positively associated with clinical proxy measures of adiposity including weight (ρ = 0.39), BMI (ρ = 0.43) and waist circumference (ρ = 0.39) (all P < 0.05). Fat mass and % body fat were correlated with T levels (ρ = 0.42 and 0.38 respectively, both P < 0.05). T correlated with overall and superficial abdominal fat (ρ = 0.34 and 0.37 respectively, both P < 0.05) but not with visceral adipose tissue. T increased with greater thigh fat (ρ = 0.49, P < 0.05) in both superficial and deep depots (ρ = 0.50 and 0.35 respectively, both P < 0.05). CONCLUSION Our results suggest that postmenopausal women with higher circulating T levels have both higher regional and overall body adiposity. These findings underscore the sexual dimorphism in the relationship between serum androgen levels and adiposity.

Abstract
Background. The chronological age of the ordinary Ghanaian has often been difficult to verify as registration at birth is not compulsory. Consequently, an accurate method of age determination is needed in competitive age-restricted sports.Objective. To evaluate the age of Ghanaian soccer players who are aspiring to play for the national under-17 (U17) team, using the degree of fusion of the distal radius on magentic resonance imaging (MRI) and comparing it with the Fédération Internationale de Football Association (FIFA) MRI grading.Methods. MRI scans of the left wrists of 86 players aspiring to play for the national U17 football team were recruited for the study during a ‘justify your inclusion tournament’ organised by the Ghana Football Association between June and August 2012. The study was conducted in a diagnostic centre in Accra using a 0.35T MRI scanner. The images were analysed using the previously published FIFA grading system.Results. The mean chronological age of the players was 15.4 years (standard deviation ±0.7; range 12 - 17). The study showed that 43.0% of the MRI images were grade 6 (≥17 years) in relation to the degree of fusion of the distal radius, and 93.0% of the grade 6 players were aged 15 - 16 years chronologically. There was no significant correlation between the chronological age and the degree of fusion (r=0.075; p=0.493).Conclusion. Ghanaian U17 soccer players seem to be more biologically mature than a normative population of the same age category. The lack of correlation between age category and degree of fusion supports the suspicion that most Ghanaian players may not know their true age.

Abstract
This study estimated the patient dose in chest and lumbar spine radiographic examinations in 10 hospitals in Ghana. Dose estimations were done on 1045 patients (aged, 39.6 ± 10.6 y; range 18-85 y) involving 501 (47.9%) males and 544 (52.1%) females for a total of 1495 individual projections. The entrance surface dose (ESD) for the patients was assessed by an indirect method, using the patient's anatomical data and exposure parameters utilised for the specific examination and a Quality Assurance Dose Database software developed by Integrated Radiological Services Ltd in Liverpool, UK. The study showed variations in the ESDs for chest examinations with five of the hospitals having values above the internationally recommended levels. ESDs for lumbar spine anterior-posterior and lateral projections were within acceptable limits. Diagnostic reference levels proposed by the International Commission on Radiological Protection based on patient dose data are imperative to the current Ghanaian situation and will lead to a reduction of the radiation dose.
