Non-compliance may reflect valid questions about the applicability of guideline recommendations in the local context of health care. Special consideration should be given to previously treated patients, as an important factor influencing guideline compliance. Guideline compliance may also be improved by a better strategy to retest those patients whose initial tests are negative in health care contexts where TB is frequently missed.

The purpose of this study was to compare chronotype preferences of college students from high- and low-altitude backgrounds living in a tropical setting of Ethiopia. Chronotype (morningness-eveningness) is a preference for a given time of day for physical or mental activities. The present cross-sectional study employed Horne and Osteberg Morningness-Eveningness Questionnaires to evaluate chronotype preferences. The chronotype preference of 264 male college students from varied altitude backgrounds indicated significant differences (p < 0.001). Our findings confirm our hypothesis, of the prevalence of M-types dominant chronotype among college students at low than high altitude. However, we did not confirm our second hypothesis, since students from high-altitude backgrounds were generally I-type dominant chronotype. Similarly, students' academic performances from low- compared to high-altitudes backgrounds also indicated significant differences (p < 0.003). Better academic performances were seen in students with I-type chronotype orientations from high altitudes.

ObjectiveThe objective of this study was to ascertain the effects of high-intensity chronic endurance training on cardiovascular markers of active populations and athletes.MethodsThis review was conducted in accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We used databases of PubMed, Science Direct, SPORTDiscus, Google Scholar and grey literatures with Mesh and free-text search as well as manual searches to identify relevant studies from June 2017 to September 2019. Weighted standardised mean differences and effect size of the intervention group versus the control group were calculated using a random effect model with 95% CI.ResultThere was significant improvement in high-density lipoprotein with weighted standardised mean difference and effect size=−1.06 (−1.83 to −0.30), p=0.006. We have also observed a significant reduction in low-density lipoprotein and total cholesterol with weighted standardised mean difference and effect size=−0.97 (−1.58 to −0.36), p=0.002, and = −0.78 (−1.34 to −0.22), p=0.007, respectively. There was a significant reduction in interleukin 6 (IL-6) using a fixed effect model with weighted standardised mean difference and effect size=−0.87 (−1.33 to −0.40), p=0.0003 and C reactive protein (CRP) with weighted standardised mean differences and effect size=−0.41 (−0.73 to −0.09), p=0.01.ConclusionChronic high-intensity endurance training improves healthy lipid profiles (increase high-density lipoprotein, decreased low-density lipoprotein and total cholesterol). And decreased inflammatory markers (IL-6 and CRP) independent of age and sex and cannot be associated with an increased risk of developing cardiovascular disease.PROSPERO registration numberCRD 42017081369.
