Summary of the effect of an exercise intervention on antenatal depression and the optimal program: a systematic review and Meta-analysis.

OBJECTIVE: This study aimed to examine the effect of exercise intervention for antenatal depression using meta-analysis and to propose the best exercise intervention program. METHODS: Review Manager 5.3 was used to analyze 17 papers with 2224 subjects by setting five moderators, including type, time, frequency, period, and format of exercise intervention, and a random-effects model was used to test for overall effect, heterogeneity, and publication bias. RESULTS: (1) The effect size of the exercise intervention on antenatal depression was d = -0.56, which reached a good effect and was statistically significant; b (2) The effect size of the exercise type on antenatal depression was Yoga and a combination of aerobic exercise in order of intervention; (3) the single intervention duration of 10-75 min all had a good effect on antenatal depression, and 30-60 min had the best effect; (4) the intervention frequency of 3 to 5 times/week had the greatest amount of intervention effect on maternal depression; (5) exercise lasting 6-10 weeks had a good intervention effect on antepartum depression, and the amount of effect decreased gradually with the extension of time; (6) In terms of exercise format, the amount of intervention effect on maternal depression was in the order of group exercise, individual + group exercise. CONCLUSIONS: Exercise intervention can significantly alleviate antenatal depression symptoms. The best exercise program for exercise intervention for antenatal depression is: Yoga and a combination of aerobic exercise intervention effects are more prominent, and the intervention effect of Yoga is the best. The use of group exercise 3-5 times per week for 30-60 min for 6-10 weeks was more likely to achieve the desired intervention effect of improving antenatal depression.

Summary of the effect of an exercise intervention on elderly with mild cognitive impairment: A systematic review and meta-analysis.

BACKGROUND: Many randomized controlled trials have demonstrated that exercise benefits cognitive function in patients with mild cognitive impairment (MCI), but less attention has been paid to the development of exercise programs in this population. OBJECTIVE: This study aimed to assess the effect of exercise intervention for elderly with MCI and provide the most effective exercise intervention plan. METHODS: We searched 4 international databases (PubMed, EMBASE, Web of Science, Cochrane Library) and 4 Chinese databases (Chinese National Knowledge Infrastructure, VIP database and Wanfang database) for studies on exercises associated with MCI up to September 25, 2022. The resulting standardized mean differences (SMD) and 95% confidence intervals were statistically analyzed using Review Manager 5.3 software. RESULTS: A total of 20 RCTs were comprised in this meta-analysis, including 1393 participants. The results of the meta-analysis revealed that exercise had positive effects on cognitive function in elderly with MCI and was statistically significant (SMD = 1.25, 95%CI: [0.88,1.62], P < .00001). Subgroup analysis showed that the most significant factor was the Peterson 2004 criteria, multi-exercise, 35 to 50 minutes/times, <3 times/3 to 5 times per week, >16 weeks and medium intensity. CONCLUSION: Exercise intervention can significantly alleviate cognition in elderly with MCI. The best exercise program for exercise intervention for MCI is: multi-exercise, 35 to 50 minutes/times, 3 to 5 times/week, and exercise cycle for more than 16 weeks with medium intensity, has the best effect. Plus, more RCTs with larger sample sizes will be required in the future to demonstrate the link between exercise duration, intensity, and cognitive function.

A study on the relationship between yoga exercise intervention and the comprehensive well-being of female college students.

Background: Due to the influence of theories, tools, and methodologies in studying well-being, sports science has predominantly focused on subjective well-being, with less attention given to psychological well-being and even less to the integrated study of comprehensive well-being. This study aims to analyze the relationship between yoga exercise intervention and the comprehensive well-being of college students and to explore the mechanism of a yoga exercise intervention to improve the comprehensive well-being of female college students. Methods: With 92 female college students as subjects, the "Comprehensive Well-being Scale" was used, and research methods such as yoga exercise intervention, questionnaire surveys, qualitative analysis, expert interviews, and statistical analysis were employed to investigate the role of a yoga exercise intervention on the comprehensive well-being of female college students. Results: Among the nine dimensions of comprehensive well-being, the three dimensions of subjective well-being and the two dimensions of psychological well-being (health concern and personality growth) of female college students were significantly improved. Additionally, four other dimensions of psychological well-being also showed significant improvement. Furthermore, the improvement in the life satisfaction of female college students' subjective well-being was mainly achieved through yoga meditation, while partner yoga posture practice could help individuals gradually form a stable pattern of altruistic behavior. Conclusion: Yoga exercise intervention can improve the comprehensive well-being of female college students and can be an effective counseling method for college students' mental health education.

[An approach for the measurement of the surface area of scalp flap over the cranial defect after decompressive craniectomy].

OBJECTIVE: To introduce a simple, fast and universal measuring method used in measurement of the surface area of scalp flap over the cranial defect after decompressive craniectomy. METHODS: The first step: CT images of the patient with craniocerebral trauma after decompressive craniectomy were obtained and imported into Mimics. The second step: based on the defined threshold, the 3D geometric models of brain and skull were reconstructed after the original Dicom format pictures three-dimensional processed by Mimics. The third step: based on the two builded 3D models, utilizing the segmentation and measurement tools of Mimics to conduct cutting, splitting and measuring operations for the 3D model of brain. The forth step: estimating the surface area of scalp flap over the removed bone flap by using mathematical computation methods. RESULTS: The application of the introduced method estimated the surface area of scalp flap over the cranial defect of different people with different position of craniocerebral trauma. CONCLUSIONS: This paper introduces a simple, fast and universal new measuring method. We can conveniently estimate the surface area of scalp flap by using the introduced method.
