Are Traditional Health Care Practices for Children with Mental Health Problems in the Tamale Metropolis in Ghana as Effective as Psychological Interventions?

This study investigates the extent to which traditional Health Care practices for children with mental health problems in the Tamale Metropolis in Ghana are as effective as psychological interventions. The study reviews existing work on traditional health care practices, psychological interventions for mental health patients and coping strategies for parents and/or family members of children with mental health problems to build a conceptual framework that is appropriate for examining health care practices for children with mental health problems in Tamale, in northern Ghana. The study details the traditional health care practices that children with mental health problems receive from especially traditional healers who believe that issues of mental health are caused by the activities of witches and wizards. The findings of this study suggest that the burden of care for children with mental health problems solely rests on parents, family members, and traditional healers and to a lesser extent the psychiatric hospital. Some coping strategies, however, have been adopted by parents of children with mental health problems, the major strategy being the ‘God motif’ by which parents are able to ‘survive’ stigmatization and stress.

Women’s Informal Water Vending as An Economic Activity and Its Effects on Household Bargaining Dynamics in Northern Ghana

This article elaborates the importance of informal women’s work in northern Ghana in general and specifically in Tamale with particular attention to water vending. Particular attention is paid to an examination of the different forms of water vending and the ways in which they are gendered as well as their seasonal variations. The bargaining strengths of women who are engaged in water vending as an economic activity is also highlighted in this article. A combination of secondary and primary data is employed in the analysis of data for this article, to identify the opportunities and challenges that water vending poses for married women and to show how looking at wet and dry season water vending, offers an opportunity to examine how variations in the significance and value of women’s informal work in this sector influences gender bargaining within households.

Recruiting population controls for case-control studies in sub-Saharan Africa:The Ghana Breast Health Study

BackgroundIn case-control studies, population controls can help ensure generalizability; however, the selection of population controls can be challenging in environments that lack population registries. We developed a population enumeration and sampling strategy to facilitate use of population controls in a breast cancer case-control study conducted in Ghana.MethodsHousehold enumeration was conducted in 110 census-defined geographic areas within Ghana’s Ashanti, Central, Eastern, and Greater Accra Regions. A pool of potential controls (women aged 18 to 74 years, never diagnosed with breast cancer) was selected from the enumeration using systematic random sampling and frequency-matched to the anticipated distributions of age and residence among cases. Multiple attempts were made to contact potential controls to assess eligibility and arrange for study participation. To increase participation, we implemented a refusal conversion protocol in which initial non-participants were re-approached after several months.Results2,528 women were sampled from the enumeration listing, 2,261 (89%) were successfully contacted, and 2,106 were enrolled (overall recruitment of 83%). 170 women were enrolled through refusal conversion. Compared with women enrolled after being first approached, refusal conversion enrollees were younger and less likely to complete the study interview in the study hospital (13% vs. 23%). The most common reasons for non-participation were lack of interest and lack of time.ConclusionsUsing household enumeration and repeated contacts, we were able to recruit population controls with a high participation rate. Our approach may provide a blue-print for others undertaking epidemiologic studies in populations that lack accessible population registries.</div

Cross-ancestry GWAS meta-analysis identifies six breast cancer loci in African and European ancestry women.

Our study describes breast cancer risk loci using a cross-ancestry GWAS approach. We first identify variants that are associated with breast cancer at P < 0.05 from African ancestry GWAS meta-analysis (9241 cases and 10193 controls), then meta-analyze with European ancestry GWAS data (122977 cases and 105974 controls) from the Breast Cancer Association Consortium. The approach identifies four loci for overall breast cancer risk [1p13.3, 5q31.1, 15q24 (two independent signals), and 15q26.3] and two loci for estrogen receptor-negative disease (1q41 and 7q11.23) at genome-wide significance. Four of the index single nucleotide polymorphisms (SNPs) lie within introns of genes (KCNK2, C5orf56, SCAMP2, and SIN3A) and the other index SNPs are located close to GSTM4, AMPD2, CASTOR2, and RP11-168G16.2. Here we present risk loci with consistent direction of associations in African and European descendants. The study suggests that replication across multiple ancestry populations can help improve the understanding of breast cancer genetics and identify causal variants

Early results of prostate cancer radiation therapy: an analysis with emphasis on research strategies to improve treatment delivery and outcomes

<p>Abstract</p> <p>Background</p> <p>There is scant data regarding disease presentation and treatment response among black men living in Africa. In this study we evaluate disease presentation and early clinical outcomes among Ghanaian men with prostate cancer treated with external beam radiotherapy (EBRT).</p> <p>Methods</p> <p>A total of 379 men with prostate cancer were referred to the National Center for Radiotherapy, Ghana from 2003 to 2009. Data were collected regarding patient-and tumor-related factors such as age, prostate specific antigen (PSA), Gleason score (GS), clinical stage (T), and use of androgen deprivation therapy (ADT). For patients who received EBRT, freedom from biochemical failure (FFbF) was evaluated using the Kaplan-Meier method.</p> <p>Results</p> <p>Of 379 patients referred for treatment 69.6% had initial PSA (iPSA) > 20 ng/ml, and median iPSA was 39.0 ng/ml. A total of 128 men, representing 33.8% of the overall cohort, were diagnosed with metastatic disease at time of referral. Among patients with at least 2 years of follow-up after EBRT treatment (n=52; median follow-up time: 38.9 months), 3- and 5-year actuarial FFbF was 73.8% and 65.1% respectively. There was significant association between higher iPSA and GS (8–10 vs. ≤7, p < 0.001), and T stage (T3/4 vs. T1/2, p < 0.001).</p> <p>Conclusions</p> <p>This is the largest series reporting on outcomes after prostate cancer treatment in West Africa. That one-third of patients presented with metastatic disease suggests potential need for earlier detection to permit curative-intent therapy. Data from this study will aid in the strategic development of prostate cancer research roadmap in Ghana.</p

Evaluating Polygenic Risk Scores for Breast Cancer in Women of African Ancestry.

BACKGROUND: Polygenic risk scores (PRSs) have been demonstrated to identify women of European, Asian, and Latino ancestry at elevated risk of developing breast cancer (BC). We evaluated the performance of existing PRSs trained in European ancestry populations among women of African ancestry. METHODS: We assembled genotype data for women of African ancestry, including 9241 case subjects and 10 193 control subjects. We evaluated associations of 179- and 313-variant PRSs with overall and subtype-specific BC risk. PRS discriminatory accuracy was assessed using area under the receiver operating characteristic curve. We also evaluated a recalibrated PRS, replacing the index variant with variants in each region that better captured risk in women of African ancestry and estimated lifetime absolute risk of BC in African Americans by PRS category. RESULTS: For overall BC, the odds ratio per SD of the 313-variant PRS (PRS313) was 1.27 (95% confidence interval [CI] = 1.23 to 1.31), with an area under the receiver operating characteristic curve of 0.571 (95% CI = 0.562 to 0.579). Compared with women with average risk (40th-60th PRS percentile), women in the top decile of PRS313 had a 1.54-fold increased risk (95% CI = 1.38-fold to 1.72-fold). By age 85 years, the absolute risk of overall BC was 19.6% for African American women in the top 1% of PRS313 and 6.7% for those in the lowest 1%. The recalibrated PRS did not improve BC risk prediction. CONCLUSION: The PRSs stratify BC risk in women of African ancestry, with attenuated performance compared with that reported in European, Asian, and Latina populations. Future work is needed to improve BC risk stratification for women of African ancestry
