Efficacy of MitoHeal® supplementation on adult skin quality and patient satisfaction: a randomized, double-blind, placebo-controlled, pilot study.

AIM: Polyphenols, the most abundant natural biochemicals found in fruits, vegetables seeds, red wine, cocoa, coffee and spices, may have cosmetic and health effects. METHODS: This was a 1-month randomized, placebo-controlled study, approved by the institutional review board. In total, 40 adults (mean age 44.65 years) were randomized to one of three groups: MitoHeal® 500 mg/day, MitoHeal® 1000 mg/day or placebo drink. Measurements were expert rating of professional photos of skin quality and patient self-reported skin satisfaction at Days 0 and 30. RESULTS: The photographs and self-report assessments revealed that, compared with placebo, MitoHeal supplementation resulted in improvements in skin quality and patient satisfaction from Day 0 to Day 30, with a dose-response relationship often evidenced (P < 0.05). No adverse events were reported. CONCLUSION: Pilot data revealed that MitoHeal supplementation might be effective for improving skin quality and patient satisfaction. Larger sample sizes and trial durations are needed to determine the effects of MitoHeal supplementation on beauty and overall health.

Exercise is Medicine on Campus: A Scoping Review of Evidence 2009 to 2021 and Call to Action.

ABSTRACT: The Exercise is Medicine On Campus (EIM-OC) program began in 2009 at Chatham University by Dr. Robert Sallis, Dr. Carena Winters, and ACSM leadership. The vision of EIM-OC is "to see all campus and community members across multiple disciplines discover, share, and adopt the principles of EIM that will help change the culture of physical activity and chronic disease prevention and management campus wide." Although EIM-OC maintains close track of programmatic details, such as the number of registered and recognized institutions, a comprehensive review of EIM-OC publications has not been previously reported. The purpose of this scoping review was to 1) identify and examine all peer-reviewed evidence of EIM-OC, including scholarly articles and published abstracts of presentations; 2) analyze the key themes of EIM-OC implementation and outcomes; and 3) identify gaps in the literature. The scoping review covered all peer-reviewed publications, including scholarly articles and published abstracts, from 2009 to December 2021. In total, 9 scholarly articles and 46 published abstracts were included in this review. The articles and abstracts covered a wide range of topics, including gold level (physical activity assessment and exercise referral), silver level (physical activity education), and bronze level (physical activity awareness and promotion) activities, as well as evaluation of EIM-OC programming. Now that EIM-OC programming is firmly established, we now call on campuses and leaders to strengthen their reporting of EIM-OC outcomes at all levels: gold, silver, and bronze. Publishing research evidence will strengthen EIM-OC programming and initiatives. Specifically, we encourage publishing scholarly articles and using broad means for increasing dissemination.

Physical Activity Assessment and Promotion in Clinical Settings in the United States: A Scoping Review.

OBJECTIVE: The purpose of this scoping review was to systematically examine interventions that focused on physical activity assessment and promotion in clinical settings in the United States. DATA SOURCES: A literature search was performed in 6 major databases to extract published peer-reviewed studies from 2008 to 2019. INCLUSION AND EXCLUSION CRITERIA: Interventions with practicing health professionals in the United States who performed physical activity assessment and promotion with adult patients 18 years of age and older. Studies were excluded if they were published in non-English, observational or case study designs, or gray literature. DATA EXTRACTION: Studies were screened and coded based on the population, intervention, comparison, outcomes and study setting for scoping reviews (PRISMA-ScR) framework. Of 654 studies that were identified and screened for eligibility, 78 met eligibility criteria and were independently coded by two coders. DATA SYNTHESIS: Data were synthesized using qualitative and descriptive methods. RESULTS: Forty-three of the included studies were randomized controlled trials with a majority being delivered by physicians and nurses in primary care settings. Fifty-six studies reported statistically significant findings in outcome measures such as anthropometrics and chronic disease risk factors, with 17 demonstrating improvements in physical activity levels as a result of the interventions. CONCLUSION: The assessment and promotion of physical activity in clinical settings appears to be effective but warrants continued research.

Effect of a Free-Living Ketogenic Diet on Feasibility, Satiety, Body Composition, and Metabolic Health in Women: The Grading Level of Optimal Carbohydrate for Women (GLOW) Study.

OBJECTIVE: The study's purpose was to examine a free-living, ketogenic diet (WFKD) on feasibility, satiety, body composition, and metabolic health in women. METHODS: Twenty-two women (age (yr.) 42.2 ± 8.1, Ht. (cm) 164.2 ± 5.9, BMI 27.3 ± 6.0) participated in a 21-day, free-living dietary intervention. Daily ketone measurements and satiety/craving surveys, weekly diet records, and PRE and POST assessments of anthropometrics, body composition, blood pressure, and fasted capillary-blood glucose (BG) and cholesterol panels were collected. RESULTS: Women maintained calories (PRE: 1938 kcal vs POST: 1836 kcal) and protein (PRE: 17% vs POST: 20%) but decreased carbohydrate (PRE: 36% vs POST: 13%) and increased fat (PRE: 45% vs POST: 65%) PRE to POST (p ≤ 0.05). Daily self-reports suggested no changes in satiety or food cravings between PRE, WK 1, WK 2, and WK 3. Ketones increased (PRE 0.3 ± 0.2 mmol vs POST 0.8 ± 0.6 mmol) PRE to POST with significant differences between PRE and all other time points (p ≤ 0.05). Bodyweight (PRE: 73.9 kg vs POST: 72.3 kg) and body fat (PRE: 28.9 ± 13.4 kg vs POST 27. 4 ± 13.5 kg) decreased but there were no differences in fat-free mass PRE to POST (p ≤ 0.05). Systolic blood pressure decreased (PRE: 119.2 ± 8.9 mmHg vs POST: 109.5 ± 10.9 mmHg), diastolic blood pressure increased (PRE: 74.1 ± 7.5 mmHg vs POST: 78.8 ± 7.4 mmHg), and BG improved (94.0 ± 8.3 mg/dL vs POST 89.9 ± 9.0 mg/dL) PRE to POST (p ≤ 0.05). No differences were observed in total cholesterol (TC), high-density lipoprotein (HDL), and triglycerides (TG) but TC/HDL decreased and low-density lipoprotein increased PRE to POST (p ≤ 0.05). CONCLUSION: Women were able to maintain calories, improve body composition, blood pressure, and BG, increase ketones, and improve some but not all cholesterol markers after 21 days on a free-living WFKD.

The effect of physical activity on 18-month weight change in overweight adults.

Few studies have been conducted that have examined the long-term effect of different doses of physical activity (PA) on weight change in overweight adults without a prescribed reduction in energy intake. This study examined the effect of different prescribed doses of PA on weight change, body composition, fitness, and PA in overweight adults. Two hundred seventy-eight overweight adults (BMI: 25.0-29.9 kg/m²; age: 18-55 years) with no contraindications to PA were randomized to one of three intervention groups for a period of 18 months. MOD-PA was prescribed 150 min/week and HIGH-PA 300 min/week of PA. Self-help group (SELF) was provided a self-help intervention to increase PA. There was no recommendation to reduce energy intake. MOD-PA and HIGH-PA were delivered in a combination of in-person and telephone contacts across 18 months. 18-month percent weight change was -0.7 ± 4.6% in SELF, -0.9 ± 4.7% in MOD-PA, and -1.2 ± 5.6% in HIGH-PA. Subjects were retrospectively grouped as remaining within ±3% of baseline weight (WT-STABLE), losing >3% of baseline weight (WT-LOSS), or gaining >3% of baseline weight (WT-GAIN) for secondary analyses. 18-month weight change was 0.0 ± 1.3% for WT-STABLE, +5.4 ± 2.6% for WT-GAIN, and -7.4 ± 3.6% for WT-LOSS. 18-month change in PA was 78.2 ± 162.6 min/week for WT-STABLE, 74.7 ± 274.3 for WT-GAIN, and 161.9 ± 252.6 min/week for WT-LOSS. The weight change observed in WT-LOSS was a result of higher PA combined with improved scores on the Eating Behavior Inventory (EBI), reflecting the adoption of eating behaviors to facilitate weight loss. Strategies to facilitate the maintenance of these behaviors are needed to optimize weight control.

Exercise training increases intramyocellular lipid and oxidative capacity in older adults.

Intramyocellular lipid (IMCL) has been associated with insulin resistance. However, an association between IMCL and insulin resistance might be modulated by oxidative capacity in skeletal muscle. We examined the hypothesis that 12 wk of exercise training would increase both IMCL and the oxidative capacity of skeletal muscle in older (67.3 +/- 0.7 yr), previously sedentary subjects (n = 13; 5 men and 8 women). Maximal aerobic capacity (Vo(2 max)) increased from 1.65 +/- 0.20 to 1.85 +/- 0.14 l/min (P < 0.05), and systemic fat oxidation induced by 1 h of cycle exercise at 45% of Vo(2 max) increased (P < 0.05) from 15.03 +/- 40 to 19.29 +/- 0.80 (micromol.min(-1).kg fat-free mass(-1)). IMCL, determined by quantitative histological staining in vastus lateralis biopsies, increased (P < 0.05) from 22.9 +/- 1.9 to 25.9 +/- 2.6 arbitrary units (AU). The oxidative capacity of muscle, determined by succinate dehydrogenase staining intensity, significantly increased (P < 0.05) from 75.2 +/- 5.2 to 83.9 +/- 3.6 AU. The percentage of type I fibers significantly increased (P < 0.05) from 35.4 +/- 2.1 to 40.1 +/- 2.3%. In conclusion, exercise training increases IMCL in older persons in parallel with an enhanced capacity for fat oxidation.
