Purpose Type 2 diabetes poses a major global health threat both in the developed and developing countries. Factors responsible for the soaring epidemic of T2DM in the developing countries include urbanization, ageing population, physical inactivity and increasing obesity rates. Our aim was to determine the pattern of obesity among patients with T2DM at the Aminu Kano Teaching Hospital (AKTH), Kano, Northwestern Nigeria. Patients and methods We consecutively recruited 220 patients with type 2 diabetes attending the diabetes clinic of AKTH for the study. Patients with Type 1 diabetes, patients who could not stand or are wheelchair bound and pregnant women were excluded from the study. A pretested questionnaire was used to collect data on socio-demographic characteristics, treatment history for diabetes and history of hypertension from each participant. Results Of the 220 patients recruited for this study, 97(44.1%) were men, while 123(55.9%) were women. The prevalence of generalized obesity among the study participants was 27.4% (women -30.9% vs men- 22.7%, X2=4.76, p=0.190). Grades I. II and III obesity were found in 17.3%, 5.9% and 3.2% of the study participants, respectively. All the participants with grade III obesity were women. Central obesity defined by WC was detected in 111(50.5%) [20(20.6%) men and 91(73.9%) women, X2=1.93, p=0.001]. Obesity defined by WHR was recorded in 182(82.7%) participants [80(43.9%) men and 102(56.0%) women, X2= 1.97, 0.001]. Using a cut-off of ≥0.5, abnormal WhtR was detected in 179(81.4%) [72(40.2%) men and 107(59.8%) women, X2= 5.82, p=0.01], while using a cut-off of ≥0.6, abnormal WhtR was detected in 84(38.2%) participants [29 (34.5%) men and 55(65.5%) women, X2=6.38, p=0.09]. Hypertension was detected in 103(46.8%) participants, with a higher prevalence among women compared with men [46.3. % vs 47.4%, X2= 1.03 p=0.87]. Conclusion The prevalence of obesity in our cohort of patients with type 2 diabetes was high. The predominant form of obesity was central obesity, which was most prevalent when indexed by WHR. The WhtR was as good as the WHR, but fared better than WC in detecting central obesity in our patients.

BACKGROUND There are conflicting reports of sex differences in HIV treatment outcomes in Africa. We investigated sex disparities in treatment outcomes for adults on first line antiretroviral treatment (ART) in Nigeria. METHODS We compared clinical and immunologic responses to ART between HIV-infected men (n=205) and women (n=140) enrolled in an ART program between June 2004 and December 2007, with follow-up through June 2014. We employed Kaplan-Meier estimates to examine differences in time to immunologic failure and loss to follow-up (LTFU), and generalized estimating equations to assess changes in CD4+ count by sex. RESULTS Men had lower baseline mean CD4+ count compared to women (327.6 cells/µL vs 413.4, respectively, p

Background: Catheter-related blood stream infection (CRBSI) contributes to morbidity and mortality among patients on haemodialysis (HD). We carried out a systematic review and meta-analysis to assess the efficacy of antimicrobial lock solutions (ALS) in preventing CRBSI.Method: Electronic search of randomised controlled trials (RCTs) comparing ALS with other agents was performed up to January 2013. DerSimonian and Laird meta-analysis was performed to obtain pooled relative risk (RR) from which efficacy of ALS and numbers needed to treat (NNT) were calculated. In a restricted analysis, pooled RRs where compared using a test of interaction to calculate ratio of relative risks (RRR). Meta-regression analysis was employed to explore sources of heterogeneity.Results: Sixteen RCTs involving 2016 individuals met the inclusion criteria. The efficacy of ALS in preventing CRBSI was 80% with NNT of 3 patients to prevent one CRBSI. The RR of CRBSI was significantly lower with ALS compared with heparin-only lock solution [RR {95% confidence interval (CI)} = 0.20 (0.13-0.31)]. With low dose (≤ 5 mg/ml) and high dose (40 mg/ ml) gentamicin-containing ALS, the RR (95% CI) of developing CRBSI was 0.03 (0.01-0.13) and 0.18 (0.03-0.98), respectively, with no significant difference [RRR (95% CI) = 0.2 (0.02-1.61), p = 0.126]. Heterogeneity was explained by a statistically significant association between rate of CRBSI and catheter days (p = 0.037). Conclusion: ALS are effective in preventing CRBSI. Low dose gentamicin should be preferred over high dose gentamicin as an ALS because it offers similar benefit in preventing CRBSI with lesser risk of toxicity from systemic leakage and subsequent development of drug resistance.
