AI Article Synopsis
- Researchers studied how grip strength affects the quality of life for older adults to see how strong they need to be to stay healthy and happy.
- They measured grip strength in 105 people over 60 years old and found that stronger grip is linked to better physical health but not much to mental health.
- A specific grip strength level was identified, which older adults need to reach to improve or maintain their quality of life as they age.
Article Abstract
Background: Grip strength have been showed diverse associations with quality of life for the older adult population in the literature, still there is lack of evidence of the threshold value of grip strength for maintaining good quality of life in older adults. The purpose of this study was to study the dose-effect relationship between grip strength and quality of life in the older adult, and to explore the factors affecting quality of life in the older adult, so as to provide effective theoretical basis for realizing healthy aging.
Methods: A total of 105 older adult people over 60 years old were selected from 3 communities in Beijing. Grip strength was measured by hand dynamometer apparatus and quality of life was assessed by 36-item Short-Form (SF-36). On the basis of controlling confounding factors, the dose-effect relationship between grip strength and quality of life was analyzed with the restricted cubic spline model.
Results: The results showed that there was a dose-effect relationship between grip strength and physical component summary (PCS) ( < 0.01). However, grip strength was not significantly associated with mental component summary (MCS) ( > 0.05). The threshold value of grip strength for male and female is 34.75 and 23.2 kg, for normal weight group and overweight and obesity group is 24.82 and 29.00 kg, for 60-69, 70-79, 80+ years group is 24.88, 23.37, and 22.97 kg, respectively. When the grip strength value is lower than the threshold value, the increase of grip strength was related to significant improvement of quality of life of the older adult, and when the grip strength value is higher than the threshold value, the quality of life can be maintained in good condition.
Conclusion: A dose-effect relationship was found between grip strength and physical health in quality of life. Results of our study indicated that the grip strength of the older adults needed to be greater than certain threshold values to maintain good quality of life.

Effectiveness of rehabilitation in hospitalized hemodialysis patients as compared with rehabilitation in hospitalized patients not on hemodialysis: a retrospective cohort study.
J Nephrol

Dialysis Division, Kaikoukai Healthcare Group, Nagoya, Aichi, Japan.
Background: The effectiveness of rehabilitation aimed at improving the activities of daily living and physical functions may differ between hospitalized patients undergoing hemodialysis (HD) and not undergoing HD (non-HD). The aim of the present study was to compare the outcomes of rehabilitation between hospitalized HD and non-HD patients.
Methods: This was a retrospective cohort study of inpatients who underwent rehabilitation.
Tendon Inversion Improves Tendon-to-Bone Healing in a Rat Bicep Tenodesis Model.

Purpose: Tendon-to-bone repair remains a surgical challenge. Although bone tunnel fixation is a common surgical technique whereby soft tissue is expected to heal against a bone tunnel interface, contemporary methods have yet to recapitulate biomechanical similarity to the native enthesis. In this study, we aimed to understand how inside-out longitudinal tendon inversion affects bone tunnel healing with the hypothesis that inversion removes the gliding epitenon surface to facilitate interface healing.

We sought to evaluate the effects of a 12-week pulmonary rehabilitation (PR) program on lung function, mechanics, as well as pulmonary and systemic inflammation in a cohort of 33 individuals with moderate to severe post-COVID-19. : The pulmonary rehabilitation (PR) program employed a combination of aerobic and resistance exercises. Thirty minutes of treadmill training at 75% of the maximum heart rate, combined with 30 min resistance training consisting of 75% of one maximum repetition, three times a week throughout 12 weeks.

Japanese quails () are sensitive to zinc (Zn) deficiency, a mineral essential for growth, development, and bone health. This study evaluated the effects of different levels of Zn in the diet on zootechnical performance, organ and carcass weight, and tibial breakage resistance in quails from 1 to 42 days of age. A 5 × 2 factorial design was used, consisting of five Zn levels (30, 60, 90, 120, and 150 mg/kg) and two thermal environments (thermal comfort and heat stress), with five replicates of 10 birds per treatment.

Methods: Forty porcine menisci were randomly assigned to each suture configuration with all-inside repair. All specimens were subjected to cyclic loading for 1000 cycles, followed by a load-to-failure test.
