Effect of the knee replacement surgery on activity level based on ActivPAL: a systematic review and meta-analysis study.

BACKGROUND: The knee replacement (KR) surgery aims to restore the activity level and reduce the risk of experiencing disabilities. The outcomes of this surgery are evaluated mainly with subjective tools or low validity objective tools. However, the effect of the surgery on activity level using high validity objective accelerometer is still in question. METHODS: A systematic review and meta-analysis were conducted to evaluate the benefit of KR surgery alone to enhance physical activity recommendations based on high validity accelerometer. Two independent reviewers evaluated five electronic databases (Cochrane-Central-Register-of-Controlled Trials, EMBASE, PubMed, Web of Science, and Scopus) to find relative studies between January 2000 and October 2021. The quality assessments and risk of bias assessments were examined. RESULTS: Three articles were included with 202 participants (86 males, 116 females), with an average age of 64 years and an average 32 kg/m2 body mass index. The results found that the number of steps was significantly improved up to 36.35 and 45.5% after 6-months and 1-year of the surgery, respectively. However, these changes did not meet the recommended activity level guideline and could be related to the patients' health status and their activity level before the surgery. No significant changes were seen in sedentary time, standing time, and upright time after 6-months and 1-year follow-ups. Heterogeneity among studies was low to moderate (0-63%). CONCLUSION: Knee replacement surgery is an effective treatment for improving patients' quality of life with severe knee injuries. However, various factors impact the success of surgical and achieving maximum benefit of the surgery. One factor, sedentary time, can be reduced by implementing pre-and post-surgery exercise or physical activity recommendations. Further studies are needed to understand the benefit of surgery with or without rehabilitation assessed using high validity monitors.

Attention Deficit Hyperactivity Disorder (ADHD) and Associated Factors Among First-Year Elementary School Students.

PURPOSE: Attention deficit hyperactivity disorder (ADHD) is a mental health disorder commonly in children. This study aimed to examine the prevalence of ADHD and risk factors among first-year pupils in Vietnam's urban city. PATIENTS AND METHODS: A cross-sectional study was conducted in four randomly selected primary schools. Information on 525 pupils in grade 1 (ages 6 to 7 years) was collected from 525 parents/caregivers and 28 teachers. We used the Vanderbilt Assessment Scales with two separate versions for parents and teachers to screen children with ADHD symptoms. RESULTS: Among the total of 525 pupils, 24 (4.6%) were found to have ADHD symptom types (boy: 6.5%; girl: 2.1%). The combined ADHD type accounted for the highest proportion of 3.4%, followed by predominantly inattentive and predominantly hyperactivity type. ADHD prevalence rated by teachers was higher than those rated by parents. High agreement between parents and teachers was reported (κ > 0.6). The risk of ADHD increased in male participants (aOR=4.90, 95% CI 1.51-15.85), those having a first-degree relative with ADHD (aOR=85.2, 95% CI 1.66-4371.8), in-utero exposure to tobacco smoke (aOR=4.78, 95% CI 1.31-17.44), and prenatal alcohol drinking (aOR=8.87, 95% CI 2.29-34.42). CONCLUSION: These findings suggest the importance of ADHD screening for pupils attending elementary schools, particularly those with a family history of ADHD. Public health programs should reduce prenatal exposure to the potential risk factors of ADHD (smoking and alcohol consumption).

Assessing the usability of a Willingness to Quit smoking questionnaire in a sample of active tobacco smokers: A qualitative study.

Background and objectives: Tobacco products are conceivably the most accessible addictive substances. Its use contributes to numerous negative health outcomes both in the developed and developing world. The objective of the study was to assess the usability of a Willingness to Quit smoking questionnaire; a concise questionnaire used to assess the readiness of active tobacco smokers to stop smoking, and also guiding in constructive conversations between healthcare workers and clients regarding stopping smoking.Methods: In this study, 25 active tobacco smokers and four healthcare workers of different cadres were interviewed. Participants were given the Willingness to Quit smoking questionnaire and asked to fill and comment on its usability, ease of comprehension and plausibility in the healthcare system settings.Results: All the 25 active tobacco smokers demonstrated their readiness to stop smoking. It was reported that the Willingness to Quit smoking questionnaire triggered the intention to stop smoking and effectively guided the interviews between the healthcare workers and clients who had expressed the intention of stopping smoking.Conclusion: The Willingness to Quit smoking questionnaire is a valuable tool in clinical practice as it can be used to prompt tobacco cessation dialogues between healthcare workers and clients attempting to stop smoking.
