BackgroundThere is not yet a comprehensive evidence-based epidemiological report on type 2 diabetes mellitus (T2DM) in Nigeria. We aimed to estimate country-wide and zonal prevalence, hospitalisation and mortality rates of T2DM in Nigeria.MethodsWe searched MEDLINE, EMBASE, Global Health, Africa Journals Online (AJOL) and Google Scholar for population and hospital-based studies on T2DM in Nigeria. We conducted a random-effects meta-analysis on extracted crude estimates, and applied a meta-regression epidemiological model, using the United Nations demographics for Nigeria in 1990 and 2015 to determine estimates of diabetes in Nigeria for the two years.Results42 studies, with a total population of 91 320, met our selection criteria. Most of the studies selected were of medium quality (90.5%). The age-adjusted prevalence rates of T2DM in Nigeria among persons aged 20–79 years increased from 2.0% (95% CI 1.9% to 2.1%) in 1990 to 5.7% (95% CI 5.5% to 5.8%) in 2015, accounting for over 874 000 and 4.7 million cases, respectively. The pooled prevalence rate of impaired glucose tolerance was 10.0% (95% CI 4.5% to 15.6%), while impaired fasting glucose was 5.8% (95% CI 3.8% to 7.8%). Hospital admission rate for T2DM was 222.6 (95% CI 133.1 to 312.1) per 100 000 population with hyperglycaemic emergencies, diabetic foot and cardiovascular diseases being most common complications. The overall mortality rate was 30.2 (95% CI 14.6 to 45.8) per 100 000 population, with a case fatality rate of 22.0% (95% CI 8.0% to 36.0%).ConclusionOur findings suggest an increasing burden of T2DM in Nigeria with many persons currently undiagnosed, and few known cases on treatment.
The diagnostic value of Brucella ELISA IgG and IgM has been evaluated in patients with brucellosis. Serum samples and blood cultures were collected from 83 patients with brucellosis. The sera were tested by Brucella ELISA for Brucella IgM and IgG antibodies. All 44 controls were negative for IgG and IgM. Brucella melitensis was isolated from blood cultures of 30/83 (36.1%) patients. Among the 30 bacteremic patients, 24 (80%) had an increased IgM titer of > or = 200. Of the 53 non-bacteremic patients, 41 had IgM titer > or = 200, while 22 had IgG titer of > or = 1,600. The ELISA IgM and IgG tests achieved a specificity and sensitivity of 100% and 96% respectively, while the positive and negative predictive values were 100% and 94% respectively. The Brucella ELISA is a reliable and sensitive test in the diagnosis of brucellosis. The test is rapid, easy to perform and can be automated.
BackgroundSystematic studies on the association between men’s sexual dysfunction (low sexual desire, ejaculation disorders, erectile dysfunctions, genital ulcers, testicular disorders, prostate cancer or sexually transmitted infections) and marital conflict are emerging. However, the coping strategies adopted by wives in such circumstances are not commonly reported in the literature. Male sexual functioning is vital to the marital relationship, lack of it can result in intolerable cohabitation or relationship breakdown, and could also cause infertility, infidelity, and arouse stigma in Nigeria. The understanding of coping strategies by female partners could guide in the counselling and treatment of men’s sexual health problems. Effective coping has the potential to lessen or prevent negative outcomes, and thereby could reduce marital conflict.ObjectivesThis study examined the coping strategies adopted by women whose husbands have reproductive health challenges in two of the five states with the highest proportion of divorce/separation in Nigeria.MethodsFour focus group discussions were conducted in two local government areas. The women were recruited from a quantitative couple-study for men with sexual health problems. Focus group responses were transcribed and analysed using systematic-content-analysis with thematic organisation of the summaries and systematic typologies of participants’ responses.ResultsThe results revealed the coping strategies employed by women in this environment: seeking guidance from their religious leaders and family doctors, physical-sexual-therapy, abstinence and concubinage. The participants indicated that they encountered difficulties in discussing their husbands’ sexual health problems with a third party.ConclusionThe study concludes that husband’s sexual ability is crucial to the sustenance of the marital relationship. Religious leaders and family doctors often serve as mediators to husband-wife conflict management. Counselling is recommended in cases of sexual health problems. Husbands should be encouraged to seek treatment and share their sexual challenges with their spouse. The medical officers and religious leaders could also be trained in family-conflict management.Electronic supplementary materialThe online version of this article (doi:10.1186/s12978-017-0341-2) contains supplementary material, which is available to authorized users.
