BACKGROUND Viral hepatitis is a serious public health problem affecting billions of people globally with maternal-fetal transmission on the rise. OBJECTIVES This study sought to determine the prevalence and factors associated with hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among pregnant women in the Asante Akim North Municipality, in the Ashanti region of Ghana. METHODS In this cross-sectional study 168 pregnant women were recruited from the Agogo Presbyterian hospital. Blood samples were collected for the detection of Hepatitis B Surface Antigen (HBsAg) and anti-HCV antibodies. A pretested questionnaire was used to obtain demographic data and identify the risk factors associated with the two infections. RESULTS Of the 168 participants studied, 16 (9.5%) tested positive for HBV and 13 (7.7%) tested positive for HCV representing 9.5% and 7.7% respectively. A participant tested positive for both HBV and HCV co-infection representing 0.6%. Undertaking blood transfusion, tattooing and sharing of needles were associated with hepatitis C infection (P=0.001). HBV was not associated with any of the risk factors (P>0.05). CONCLUSION Our findings suggest a high prevalence of hepatitis B and hepatitis C among pregnant women; blood transfusion, tattooing and sharing of hypodermic needles were associated with hepatitis C infection. Measures to reduce the disease and transmission burden must be introduced.

Background Vitamin D plays a major role in physiological processes that modulate mineral metabolism and immune function with probable link to several chronic and infectious conditions. Emerging data suggests a possible influence of vitamin D on glucose homeostasis. This study sought to provide preliminary information on vitamin D status among Ghanaian type 2 diabetics and assessed its association with glucose homeostasis. Methods In a case control study, 118 clinically diagnosed Type 2 Diabetes Mellitus (T2DM) patients attending Diabetic Clinic at the Nkawie Government Hospital were enrolled between October and December 2015. Hundred healthy non-diabetics living in Nkawie district were selected as controls. Structured questionnaires were administered to obtain socio-demographic data. Venous blood samples were taken from both cases and controls to estimate their FBG, Lipid profile spectrophotometrically and IPTH, 25OHD by ELISA. Statistical analyses were performed using SPSS v20.0 Statistics. Results The average age of the study participants was 58.81years for cases and 57.79year for controls. There was vitamin D deficiency of 92.4% among T2DM cases and 60.2% among the non diabetic controls. Vitamin D deficiency did not significantly associate with HOMA-β [T2DM: r2 = 0.0209, p = 0.1338 and Control: r2 = 0.0213, p = 0.2703] and HOMA-IR [T2DM: r2 = 0.0233, p = 0.1132 and Control: r2 = 0.0214, p = 0.2690] in both the controls and the cases. Conclusion Vitamin D deficiency is prevalent in both T2DM and non-diabetics. There is no association between vitamin D deficiency and insulin resistance or beta cell function in our study population. Vitamin D supplementation among type 2 diabetics is recommended.

Richard Kd Ephraim; Christian K Abongo; Samuel Asamoah Sakyi; Ruth Brenyah; Emmanuel Diabor; Isaac I. Bogoch

The utility of microhaematuria (as measured by urine reagent strips) as a surrogate marker for Schistosoma haematobium infection is not established in patients with urogenital symptoms presenting to clinical settings, although previous studies have demonstrated its utility in screening asymptomatic individuals in large community or school-based settings. In this cross-sectional study of 201 patients, multivariate analysis demonstrated microhaematuria as an independent predictor of S. haematobium infection (OR, 4.29; 95% CI, 1.6–11.9) in individuals presenting with urogenital symptoms to an outpatient medical department (OPD) at a rural Ghanaian medical center. Microhaematuria is predictive of S. haematobium infections in clinical settings in endemic regions.

Background Hepatitis B Virus (HBV) infection is an important public health problem that requires high priority efforts towards prevention and control. Active immunization is the single most important and effective preventive measure against HBV infection. As a protective measure, Ghana introduced the mass immunization program against hepatitis B infection in children in 2002 in her Expanded Programme on Immunization (EPI). This study evaluated seroconversion (the point in time when the amount of antibody in the blood becomes detectable) and seroprotection (the point in time when the amount of antibody in the blood is enough to confer protection from the antigen that induced it production) status of children under this mass immunization program and measured their antibody levels five years after immunization. Materials and Method 200 archived plasma samples of children between the ages of 1–10 years were retrieved from a previous cross-sectional study by researchers from NHRC between 2009 and 2010. Of these, 104 have completed the EPI and were screened for HBsAg. Those found to be HBsAg-seronegative were stratified into three groups according to their age at which the last vaccine was administered. Their anti-HBsAg titer levels were estimated by enzyme linked immunosorbant assay (ELISA). Results Two (1.9%) samples were HBsAg seropositive and were excluded from further analyses. 10 more samples were excluded from analyses because they were insufficient. The anti-HBs titers recorded ranged from 1.021 IU/L to 751.64 IU/L indicating a 100% seroconversion rate. In group one (0–6 months), 87.9% were seroprotected. Group two (2-3yrs) had 78.3% seroprotection and group three (3-5yrs) had 41.7% seroprotection. There was no significant difference between group 1 and 2. However, there was a significant difference between group 1 and 3 (p = 0.0137) and between group 2 and 3 (p = 0.0390) respectively. There was no significant difference between male and female children. Conclusion All the children who received doses of hepatitis B vaccine at 6, 10 and 14 weeks in the immunization program seroconverted, but their levels of protection waned with increasing years. Booster doses are therefore recommended after 5 years.

Background Advanced maternal age (AMA) has been associated with negative pregnancy outcomes. Oxidative stress (OS) and defective placental dysfunction are contributing factors. This study determined the association between AMA and adverse pregnancy outcomes, OS biomarkers and angiogenic growth mediators (AGMs) in normal pregnancies. Methods This prospective cohort study conducted at the Obstetrics and Gynaecology (O&G) Department of the Komfo Anokye Teaching Hospital (KATH) finally included 175 normal pregnant women comprising, 58 AMA (35–45 years), 55 (30–34 years) and 62 optimal childbearing age (20–29 years). Venous blood samples were collected at 28–32 weeks for soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PIGF), 8-epiprostaglandinF2-α (8-epi-PGF2α) and total antioxidant capacity (TAC) assays. Results Pregnancies of AMA had a significantly higher levels of sFlt-1, 8-epi-PGF2α and 8-epi-PGF2α: PIGF ratio but a reduced level of PIGF, TAC and PIGF: sFlt-1 ratio compared to 20–29 years (p<0.0001). A significant negative correlation between AMA and PIGF (r = -0.294; p = 0.038); TAC (r = -0.215; p = 0.001) and PIGF: sFlt-1 ratio (r = -0.457; p<0.0001) and a positive correlation with sFlt-1 (r = 0.269; p = 0.017), 8-epiPGF2α (r = 0.277; p = 0.029) and 8-epi-PGF2: PIGF ratio (r = 0.461; p<0.0001) levels were observed. The adjusted odds ratio (aOR), and 95% confidence interval, and p value for the significant independent adverse outcomes associated with AMA were emergency caesarean section [21.7 (5.9–121.3), p<00001], elective caesarean section [2.7(0.9–5.8), p = 0.0105], stillbirth [12.6(1.4–82.1), p<0.0001], post-partum haemorrhage [4.3(1.1–18.5), p = 0.0094], preterm delivery [8.2(3.5–28.4), p<0.0001], low birth weight babies [9.7(2.8–29.3), p<0.0001], birth asphyxia [3.8(1.6–12.7), p = 0.0054], Apgar score ≤ 7 after 5 min for babies [10.1(4.7–23.2), p<0.0001], placental abruption [3.5(1.3–8.4), p = 0.0117] and intrauterine growth restriction (IUGR) [4.6(2.3–12.9), p = 0.0001]. Conclusion AMA pregnancies correlate with adverse pregnancy outcomes and imbalance in OS biomarkers and AGMs. It is incumbent on health care givers to provide effective antenatal care among AMA mothers as early identification of these imbalance and treatment can prevent adverse pregnancy outcomes.

Background: Pregnant women with hypertension are at an increased risk of renal impairment. This study assessed the use of CKD-EPI and 4v-MDRD for early diagnosis of renal impairment in pregnant women with hypertension. Methods: This case-control study was conducted at Suntreso Government Hospital Kumasi, Ghana. In all, 220 pregnant women were recruited, 84 had Gestational Hypertension, 36 had Preeclampsia, with 100 normotensive pregnant women as controls. Structured Questionnaires were used to obtain socio-demographic and clinical information. 4 mL of venous blood was collected for estimation of electrolytes, urea, creatinine and uric acid; urine was collected for estimation of protein using dipstick. The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD-4) equations were used to assess and classify renal impairments. Results: Prevalence of renal impairment using CKD-EPI and MDRD-4 was 4.1% and 0.5% respectively. CKDEPI identified 22.2% of women with preeclampsia as having renal impairment whereas MDRD-4 identified 2.8%. Using CKD-EPI and MDRD-4, eGFR was significantly higher in the controls compared to the cases, (p<0.001). Sodium, chloride, urea, creatinine, uric acid was significantly increased in the hypertensive women. Conclusion: Renal impairment is common in hypertensive pregnant women. CKD-EPI is better equation in early detection of renal impairment in pregnant women and should be adopted as the tool for assessing renal dysfunction during routine antenatal examinations to prevent end-stage renal diseases.

Background Breast cancer remains a serious public health problem globally. It is particularly increasing among adolescents and premenopausal women. Breast self-examination (BSE) is the most effective and feasible means of detecting breast cancer early in developing countries. This study aimed at evaluating and comparing knowledge of BSE among secondary and tertiary school students and at revealing their attitudes and practices about BSE. Method This cross-sectional study was conducted among 1036 female secondary and tertiary school students of Kwame Nkrumah University of Science and Technology and Technology Senior High School. Data was obtained using a pretested questionnaire to access sociodemography, knowledge, attitudes, and practice of BSE among the students. Result Most students were within the age of 15–24 years; 90.9% were aware of BSE. A high level of knowledge on BSE was found in 54.5% of the students. Knowledge was significantly higher in tertiary than secondary school students (p=0.002). 24.1% of the students thought BSE could be performed anytime; however only 8.1% of the students performed BSE monthly as recommended, whilst 41.8% had never practiced. Of these, more secondary students had never practiced BSE as compared to the tertiary students. 22.3% indicated they would wait for a change in a detected breast lump before seeking medical attention. 96.3% of the participants agree BSE is a good practice which must be encouraged. Conclusion Teaching of BSE should be intensified beginning at the high school level, emphasizing practice and its benefits for early detection of breast cancer.

Background Neonatal jaundice (NNJ) is a major cause of hospital admission during the neonatal period and is associated with significant mortality. This case-control study with cross-sectional design sought to identify the possible factors associated with neonatal jaundice and assess maternal knowledge level of this condition. Methods One hundred and fifty (150) neonates comprising 100 with clinically evident jaundice and 50 without jaundice were conveniently recruited from the Trauma and Specialist Hospital in the Effutu Municipality. Blood samples were collected for the determination of serum bilirubin, glucose-6-phosphate dehydrogenase (G6PD), status and blood group (ABO and Rhesus). Well-structured questionnaire was used to collect maternal and neonate sociodemographic and clinical history. Results Majority (54%) of neonates developed jaundice within 1–3 days after birth with 10% having it at birth. Duration of labour and neonatal birth weight were associated with neonatal jaundice (P < 0.05). G6PD abnormality was found in 11 (12%) of the neonates with jaundice and ABO incompatibility was present in 18%. Neonates delivered by mothers with formal occupation and those who had prolonged duration of labour were significantly more likely to have neonatal jaundice (OR = 4.174, P = 0.003; OR = 2.389, P = 0.025, resp.). Neonates with low birth weight were also more likely to develop neonatal jaundice (OR = 2.347, P = 0.044). Only 17.3% of mothers had heard of neonatal jaundice. School was the major source of information on neonatal jaundice (34.6%). Majority of participants (mothers) did not know that NNJ can cause damage to other organs in the body (90%). Conclusion Low neonatal birth weight and prolonged duration of labour are associated with neonatal jaundice. Mothers had inadequate knowledge of neonatal jaundice and its causes.

Background Type 2 Diabetes Mellitus (T2DM) and menopause are associated with vitamin D status. Oestrogen decline during menopausal stages promotes hypovitaminosis D. However, the interplay between vitamin D, menopause, lifestyle, and T2DM cannot be overlooked. This study assessed vitamin D status among pre- and postmenopausal T2DM women and determined its association with glycemic control and influence of lifestyle habits on hypovitaminosis D. Methods This cross-sectional study was conducted at the Komfo Anokye Teaching Hospital, Kumasi, Ghana. Structured questionnaires were administered to 192 T2DM women; blood samples were collected for estimation of 25(OH) D and insulin using ELISA. Fasting blood glucose (FBG), lipid profile, glycated haemoglobin (HbA1c), and calcium were measured. Statistical analyses were performed using Graphpad Prism 6. Results The prevalence of vitamin D inadequacy was 92.2%. Hypovitaminosis D was more prevalent among the postmenopausal T2DM women (63.8% versus 58.2%). Hypovitaminosis D significantly associated with insulin [R2 = 0.01760, p = 0.0008], HbA1c [R2 = 0.3709, p = <0.0001], and FBG [R2 = 0.3465, p = 0.0001] in only the postmenopausal women. Conclusion Vitamin D deficiency is prevalent in pre- and postmenopausal T2DM but higher among postmenopausal women. Adequate vitamin D levels in both groups were associated with improved glucose control while hypovitaminosis D in the postmenopausal women was related to poorer glucose control. Vitamin D screening should be incorporated into management plan for T2DM to serve as an early tool for prevention of vitamin D deficiency.

Abstract Background Chronic kidney disease (CKD), has become a public health concern as it has been reported to cause adverse outcomes such as kidney failure and premature death. This cross sectional study compared the Kidney Disease: Improving Global Outcomes (KDIGO) and Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines in assessing the prevalence of CKD in Type 2 diabetes Mellitus (T2DM) patients. Methods We consecutively sampled a cross-section of 202 T2DM patients from the Ho municipality in the Volta region (Ghana). Structured pre-tested questionnaires were administered to obtain information on gender, age, body mass index (BMI), systolic and diastolic blood pressure, medication used, duration on medication, and duration of diabetes. Serum creatinine and urine protein were estimated using standard protocols and CKD was classified according to KDIGO and KDOQI guidelines. Results The prevalence of CKD was 63.4% and 58.4% using the KDIGO and KDOQI guidelines respectively. The prevalence of mildly decreased renal function or worse (eGFR < 60/ml/min/1.73 m2) was 10.4% for KDIGO guideline and 7.9% for KDOQI guidelines with an excellent agreement between both definitions showing bias = −0.129, 95%CI = (−0.17 to −0.08) on Bland-Altman analysis. Participants older than 70 years were more likely to have CKD when KDIGO criteria was used (P = 0.018). The prevalence of albuminuria was 47.0% with 21.9% presenting with 1+ and 2+ grades. Conclusion KDIGO guideline estimates higher prevalence of CKD than KDOQI guidelines in the same study population. KDIGO guideline might help in early detection and proper classification of CKD which will illicit stage-specific treatment.
