    The study utilised secondary data sourced from the World Development Indicators (WDI), International Labour Organisation (ILO), United Nations Educational, Scientific and Cultural Organisation (UNESCO), and the System Generalised Method of Moments (SGMM) econometric technique was used to analyse the data. Sustainable Development Goal (Goal 1) which was proxied by poverty, used as the dependent variable, while agriculture value added, employment in the agricultural sector, inequality, literacy rate, population growth rate and gross domestic savings were the explanatory variables. The study found out that both agriculture value added and employment in the agricultural sector were statistically significant in explaining poverty and negatively related to poverty in the ECOWAS sub-region. Therefore, based on the findings, the study recommended that the governments of ECOWAS countries should focus more on agriculture so as to be exporters of cash crops that will generate foreign exchange for their economies and increase savings that can be used to alleviate and eliminate poverty among the people

    The report of the occurrence of additional renal arteries in domestic animals is rare in the literature. We report a case of an additional renal artery in the left kidney found in a Red Sokoto goat cadaver. The additional renal artery originated from the abdominal aorta 3.80 cm cranial to the origin of the main renal artery. The additional renal artery was relatively long, being 6.30 cm from its origin to the cranial pole region of the kidney where it supplied the kidney. This to the best of our knowledge is the first report in the literature indexed in the Medline of an additional renal artery in a goat

    Objectives: The coronavirus disease 2019 (COVID-19) pandemic is the current public health concern. Hypoxemia has been identified as an independent risk factor for mortality in COVID-19 patients regardless of age or sex. This study therefore aimed to assess the profile of COVID-19 patients with hypoxemia in Lagos, Nigeria and identify their associated socio-demographic and clinical risk factors, predictors, and outcomes.Materials and Methods: This was a retrospective cohort study in which data were extracted from medical records of real-time polymerase chain reaction confirmed COVID-19 positive patients admitted between April and October 2020. Data extracted included age, sex, comorbidities, disease category/classification, symptoms, lowest oxygen saturation (SPO2), and outcomes. Bivariate analysis was done to test associations between hypoxemia and other variables. Multivariate analysis was done to determine significant predictors of hypoxemia.Results: A total of 266 patients were included in the study; mean (SD) 49.80 (± 16.68) years. Hypoxemia (lowest SPO2 ≤ 90 in adults and < 92% in children) was found in 102 (38.3 %) of the cases. SPO2 of hypoxemic patients ranged from 33% to 90%, Mean ±SD of 77±13%. About half of the hypoxemic cases, 53 (52%) were ≥ 60 years and mostly male 70 (68.6%). Difficulty breathing was present in 56 (55%), while the common comorbidities were hypertension 86 (32.3%) and diabetes mellitus 47 (17.7%). Age ≥ 60, difficulty breathing, and fever were independent predictors of hypoxemia. Hypoxemia was significantly associated with death (X2-42.13; P < 0.001); odds ratio 14.5 (95% CI: 5.4–38.8).Conclusion: Hypoxemia occurred in 1 out of every 3 COVID-19 patients with poor prognosis. SPO2 monitoring and early presentation in hospital for those 60 years and above or with dyspnea may be essential for early identification and treatment of hypoxemia to reduce mortality

    Parity and breastfeeding are protective against breast cancer in Nigerian women

    As the relation between reproductive factors and breast cancer risk has not been systematically studied in indigenous women of sub-Saharan Africa, we examined this in a case–control study in Nigeria. In-person interviews were conducted using structured questionnaires to collect detailed reproductive history in 819 breast cancer cases and 569 community controls between 1998 and 2006. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CI). Compared with women with menarcheal age <17 years, the adjusted OR for women with menarcheal age ⩾17 years was 0.72 (95% CI: 0.54–0.95, P=0.02). Parity was negatively associated with risk (P-trend=0.02) but age at first live birth was not significant (P=0.16). Importantly, breast cancer risk decreased by 7% for every 12 months of breastfeeding (P-trend=0.005). It is worth noting that the distribution of reproductive risk factors changed significantly from early to late birth cohorts in the direction of increasing breast cancer incidence. Our findings also highlight the heterogeneity of breast cancer aetiology across populations, and indicate the need for further studies among indigenous sub-Saharan women

    Germline mutations in CDH1 are infrequent in women with early-onset or familial lobular breast cancers

    BACKGROUND: Germline mutations in CDH1 are associated with hereditary diffuse gastric cancer; lobular breast cancer also occurs excessively in families with such condition. METHOD: To determine if CDH1 is a susceptibility gene for lobular breast cancer in women without a family history of diffuse gastric cancer, germline DNA was analysed for the presence of CDH1 mutations in 318 women with lobular breast cancer who were diagnosed before the age of 45 years or had a family history of breast cancer and were not known, or known not, to be carriers of germline mutations in BRCA1 or BRCA2. Cases were ascertained through breast cancer registries and high-risk cancer genetic clinics (Breast Cancer Family Registry, the kConFab and a consortium of breast cancer genetics clinics in the United States and Spain). Additionally, Multiplex Ligation-dependent Probe Amplification was performed for 134 cases to detect large deletions. RESULTS: No truncating mutations and no large deletions were detected. Six non-synonymous variants were found in seven families. Four (4/318 or 1.3%) are considered to be potentially pathogenic through in vitro and in silico analysis. CONCLUSION: Potentially pathogenic germline CDH1 mutations in women with early-onset or familial lobular breast cancer are at most infrequent

    Evaluation of polygenic risk scores for breast and ovarian cancer risk prediction in BRCA1 and BRCA2 mutation carriers

    Background: Genome-wide association studies (GWAS) have identified 94 common single-nucleotide polymorphisms (SNPs) associated with breast cancer (BC) risk and 18 associated with ovarian cancer (OC) risk. Several of these are also associated with risk of BC or OC for women who carry a pathogenic mutation in the high-risk BC and OC genes BRCA1 or BRCA2. The combined effects of these variants on BC or OC risk for BRCA1 and BRCA2 mutation carriers have not yet been assessed while their clinical management could benefit from improved personalized risk estimates. Methods: We constructed polygenic risk scores (PRS) using BC and OC susceptibility SNPs identified through population-based GWAS: for BC (overall, estrogen receptor [ER]-positive, and ER-negative) and for OC. Using data from 15 252 female BRCA1 and 8211 BRCA2 carriers, the association of each PRS with BC or OC risk was evaluated using a weighted cohort approach, with time to diagnosis as the outcome and estimation of the hazard ratios (HRs) per standard deviation increase in the PRS. Results: The PRS for ER-negative BC displayed the strongest association with BC risk in BRCA1 carriers (HR = 1.27, 95% confidence interval [CI] = 1.23 to 1.31, P = 8.2 x 10(53)). In BRCA2 carriers, the strongest association with BC risk was seen for the overall BC PRS (HR = 1.22, 95% CI = 1.17 to 1.28, P = 7.2 x 10(-20)). The OC PRS was strongly associated with OC risk for both BRCA1 and BRCA2 carriers. These translate to differences in absolute risks (more than 10% in each case) between the top and bottom deciles of the PRS distribution; for example, the OC risk was 6% by age 80 years for BRCA2 carriers at the 10th percentile of the OC PRS compared with 19% risk for those at the 90th percentile of PRS. Conclusions: BC and OC PRS are predictive of cancer risk in BRCA1 and BRCA2 carriers. Incorporation of the PRS into risk prediction models has promise to better inform decisions on cancer risk management
