Effects of continous and interval trainings exercises on cardiovascular characteristics of pupils in Ibadan

Objective: The focus of the paper is to examine the effects of continuous and interval trainingsexercises on cardiovascular characteristics of pupils in Ibadan, Nigeria, measured in terms heartrate, systolic blood pressure and diastolic blood pressure.Methodology: A total of one hundred and eighty (180) volunteered pupils were convenientlydrawn from four (two public and two private) primary schools in Ibadan based on type of school.The randomized classic experimental research design with two experimental and one controlgroups were employed in the study. Systematic random sampling technique was used to allocatesixty (60) participants to each of the three groups, namely: the continuous exercise (CE) andinterval exercise (IE) and the control groups. The experimental groups participated in twelveweeks exercise trainings. The cardiovascular variables measured pre­post trainings weresubjected to frequency counts, percentages, mean and standard deviation as well as analysis ofcovariance and scheffe post­ hoc for analysis and discussions.Results: Results show that the average age of the pupils was 9 years 8 months, 103 (57.2%) ofthe participants were male while 77 (42.8%) were female; the post­training mean height of theparticipants in the PRE group is 1.36±0.09m while that of weight is 29.52± 5.82kg

Effects of an eight-week lumbar stabilization exercise programme on selected variables of patients with chronic low back pain:

Lumbar stabilisation exercise has been shown to reduce pain and disability in patients with low back pain but information on its potential benefits in term of back muscle endurance is scarce. This study was aimed at investigating the effects of augmenting conventional physiotherapy with lumbar stabilization exercises on selected variables of patients with non-specific chronic low back pain (NSCLBP)

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
