Chronic low-grade inflammation that accompanies aging is associated with adverse health outcomes and may exacerbate the severity of infectious disease such as COVID-19. Resistance training (RT) has the potential to improve chronic low-grade inflammation, but the evidence remains inconclusive. This study evaluated the effects of RT on chronic low-grade inflammation in elderly adults. MEDLINE, EMBASE, Cochrane Library, CINAHL, RISS, NDSL, and KoreaMed were searched. We included studies that assessed the effect of RT on C-reactive protein (CRP), interleukin (IL)-6, IL-10, and tumor necrosis factor (TNF)-α in those aged ≥60 years. The effect size was estimated using fixed or random-effects models. Subgroup analysis was performed regarding age, health status, training method, number of exercises, intensity, weekly frequency, and duration. In the 18 randomized controlled trials (539 patients) included, RT was effective in alleviating CRP (effect size = −0.72, 95% confidence interval = −1.06 to −0.38, p < 0.001), IL-10 (−3.34, −6.16 to −0.53, p = 0.02), and TNF-α (−0.56, −1.08 to −0.03, p = 0.04) in elderly adults and tended to reduce IL-6 (−0.59, −1.18 to 0.00, p = 0.05). Subgroup analyses showed CRP reduction regardless of age, training method, number of exercises, intensity, weekly frequency, and duration. RT can be used to ameliorate chronic low-grade inflammation in elderly adults.

(1) Background: The COVID-19 outbreak has caused psychological problems worldwide. This review explored the psychological effects of online-based mindfulness programs during the COVID-19 pandemic. (2) Methods: This systematic review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized controlled trials that were published in the English language from 1 January 2020 to 31 May 2021 on online-based mindfulness programs for psychological problems due to the COVID-19 pandemic were searched in electronic databases. Quality assessment was conducted on the retrieved RCTs using the Cochrane risk of bias tool for RCTs. (3) Results: Six RCTs were included in this review. Quality appraisal of included RCTs ranged from 1 for low risk of bias to 5 for high risk of bias. There is evidence from the six RCTs that online-based mindfulness interventions may have favorable effects for reducing the levels of psychological problems, such as anxiety, depression, and stress. (4) Conclusions: Online-based mindfulness programs may be used as complementary interventions for clinical populations, healthy individuals, and healthcare workers with psychological problems due to the COVID-19 pandemic.

A randomized, double blind, controlled study was conducted to evaluate a multi-species probiotic product, Duolac(®) Care, for the efficacy in functional constipation of elderly nursing home residents. Forty participants were randomly assigned to receive either one capsule containing six bacterial strains (2.5 × 10(8) viable cells/capsule) doubly coated with proteins and polysaccharides (DC group) or one capsule containing the same bacterial strains without the coating layers outside the cell (NC group) twice a day (5 × 10(8) viable cells/day). After consumption of 2 weeks, NC group showed a significant improvement in a symptom of Rome III criteria for constipation, 'effort to evacuate', but failed to show a significant improvement in weekly defecation frequency. By contrast, DC group showed significant improvements in symptoms of 'effort to evacuate' and 'sensation of anorectal obstruction or blockage' as well as being improved in 'defecation frequency'. The quantitative analysis of the fecal bacteria revealed that the levels of all the bacterial species consumed were significantly increased after consumption in both groups. However DC group showed larger increases in the bacterial levels than NC group, and the overall bacterial levels in DC group were about 100-fold or greater than those in NC group. Therefore the improvements in the symptoms appeared to be closely associated with large increases of the bacterial species consumed. The double-coating layers of proteins and polysaccharides ensured increase in the levels of bacteria, indicating that the layers function to protect the bacteria from the digestive action in the GI tract. Therefore, Duolac(®) Care could be a treatment option in functional constipation.

This study was conducted to examine the effects of healthcare accreditation on patient safety and quality, job satisfaction and organizational commitment. One group pretest posttest design was used. The study included 405 participants, who have worked for more than one year in a general hospital. The treatment was healthcare accreditation which was prepared from Apr. 2012 and tested by Korea Institution for Healthcare Accreditation on Nov. 2012. Data was analyzed using paired t-test and One-Way ANOVA. This study found patient safety and quality(t=7.28, p=.000), job satisfaction(t=7.13, p=.000) and organizational commitment(t=3.44, p=.001) increased significantly after healthcare accreditation. The results of this study suggest that healthcare accreditation has the potential to improve patient safety and quality, job satisfaction and organizational commitment.
