ABSTRACT
BACKGROUND: Psychological disorders are common among individuals with type 2 diabetes mellitus. The effect of exercise training on psychological disorders like anxiety and depression has not been well studied in Ethiopia. The objective of this study was to assess the effect of structured aerobic and resistance exercises on psychological domains among people with type 2 diabetes mellitus in southern Ethiopia. METHOD: We began by approaching 97 type 2 diabetic patients who regularly attend follow-up clinics. The 24 study participants were randomly assigned to one of four groups: aerobic exercise (n = 6), resistance exercise (n = 6), combined aerobic and resistance exercise (n = 6), and control group (n = 6). For each arm, the interventions were a structured workout package that was completed without interrupting usual clinical follow-up. The control groups, on the other hand, were kept as follow-up clinical cases with daily routine work. A paired t-test was performed to compare the means and mean differences of each exercise group's pretest and posttest. A Tukey's post hoc test was performed to compare mean differences between groups. The significance level was set at P < 0.05. RESULT: A more significant change was obtained in the combined aerobic and resistance exercise on anxiety and depression (p = 0.006), social dysfunction (p = 0.009), loss of confidence (p = 0.012) in particular, and psychological wellbeing (p = 0.010) in general. Resistance exercise alone had a significant impact on social dysfunction (p = 0.010), anxiety and depression (p = 0.017), and psychological well-being (p = 0.012) in general. Changes in social dysfunction (p = 0.010), anxiety and depression (p = 0.030), and psychological well-being (p = 0.018) were also influenced by aerobic exercise. The study found no significant change in depression and anxiety among control groups. CONCLUSION: As a result, the combined effect of aerobic and resistance exercise had a greater influence on improving anxiety and depression, social dysfunction, loss of confidence in particular, and psychological well-being in general among patients with type 2 diabetes. In other words, the present evidence proves the betterment of combined aerobic and resistance exercises alone followed by resistance exercise alone and aerobic exercise alone compared with non-exercise groups seems to upgrade psychological wellbeing by setting up three main benefits named as: (1) anti-anxiety and depression effects; (2) anti-social dysfunction effects; and (3) anti-loss of confidence effects. This suggests that patients with diabetes who exercise regularly enhance their psychological well-being.
ABSTRACT
BACKGROUND: Visceral Leishmaniasis (VL) is a severely neglected disease affecting millions of people with high mortality if left untreated. In Ethiopia, the primary laboratory diagnosis of VL is by using an antigen from a 39-amino acid sequence repeat of a kinesin-related (rK39) of leishmania donovani complex (L. donovani), rapid diagnostic tests (RDT). Different rk39 RDT brands are available with very variable performance and studies from Ethiopia showed a very wide range of sensitivity and specificity. Therefore, a systematic review and meta-analysis were conducted to determine the pooled sensitivity and specificity of rk39 RDT in Ethiopia. METHOD: PUBMED, EMBASE, and other sources were searched using predefined search terms to retrieve all relevant articles from 2007 to 2020. Heterogeneity was assessed by visually inspecting summary receiver operating curves (SROC), Spearman correlation coefficient (rs), Cochran Q test statistics, inconsistency square (I2) and subgroup analysis. The presence and statistical significance of publication bias were assessed by Egger's test at p < 0.05, and all the measurements showed the presence of considerable heterogeneity. Quality assessment of diagnostic accuracy studies (QUADAS-2) checklists was used to check the qualities of the study. RESULTS: A total of 664 articles were retrieved, and of this 12 articles were included in the meta-analysis. Overall pooled sensitivity and specificity of the rk39 RDT to diagnose VL in Ethiopia were 88.0% (95% CI 86.0% to 89.0%) and 84.0% (95% CI 82.0% to 86.0%), respectively. The sensitivity and specificity of the rk39 RDT commercial test kits were DiaMed: 86.9% (95% CI 84.3% to 89.1%) and 82.2% (95% CI 79.3% to 85.0%), and InBios: 80.0% (95% CI 77.0% to 82.8%) and 97.4% (95% CI 95.0% to 98.8%), respectively. CONCLUSION: Referring to our result, rk39 RDT considered an essential rapid diagnostic test for VL diagnosis. Besides to the diagnostic accuracy, the features such as easy to perform, quick (10-20 min), cheap, equipment-free, electric and cold chain free, and result reproducibility, rk39 RDT is advisable to remains in practice as a diagnostic test at least in the remote VL endemic localities till a better test will come.
