An updated graphical review of molecular basis. Pharmacol Rep 2023; 75:511-543. [PMID: 37093496 DOI: 10.1007/s43440-023-00469-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 02/21/2023] [Accepted: 02/23/2023] [Indexed: 04/25/2023]
Abstract
Diabetes mellitus (DM) is a metabolic disease that activates several molecular pathways involved in neurodegenerative disorders. Metformin, an anti-hyperglycemic drug used for treating DM, has the potential to exert a significant neuroprotective role against the detrimental effects of DM. This review discusses recent clinical and laboratory studies investigating the neuroprotective properties of metformin against DM-induced neurodegeneration and the roles of various molecular pathways, including mitochondrial dysfunction, oxidative stress, inflammation, apoptosis, and its related cascades. A literature search was conducted from January 2000 to December 2022 using multiple databases including Web of Science, Wiley, Springer, PubMed, Elsevier Science Direct, Google Scholar, the Core Collection, Scopus, and the Cochrane Library to collect and evaluate peer-reviewed literature regarding the neuroprotective role of metformin against DM-induced neurodegenerative events. The literature search supports the conclusion that metformin is neuroprotective against DM-induced neuronal cell degeneration in both peripheral and central nervous systems, and this effect is likely mediated via modulation of oxidative stress, inflammation, and cell death pathways.

From Zero to Hero: Type 2 Diabetes Mellitus Patients Hike on the Way of St. James-A Feasibility Study with Analyses of Patients' Quality of Life, Diabetes Distress and Glucose Profile. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:1417.

Abstract
This study investigates the feasibility of an accompanied 5-day hiking tour (Way of St. James) for type 2 diabetes mellitus (T2DM) patients and its impact on their quality of life/well-being, diabetes distress and glucose profile. Twenty-three T2DM patients (with and without insulin therapy) participated in the study. The 120 km pilgrimage (from Ferrol to Santiago de Compostela, Spain) was accompanied by three physicians, two diabetes counselors and one sports scientist. Quality of life/well-being was assessed by the World Health Organization’s (WHO)-5 questionnaire, and diabetes distress was evaluated based on the Problem Areas in Diabetes (PAID) scale. The glucose levels of six insulin-treated patients were measured using continuous glucose monitoring (CGM) devices, considering that insulin-treated patients can be at increased risk of exercise-induced hypoglycemia. A significant improvement in quality of life/well-being was reported (p < 0.001), while diabetes distress did not change significantly (p = 0.203). Only two of the six insulin-treated patients showed moderate hypoglycemic episodes between 0.97% and 5.21% time below range per day, with glucose levels between 53−70 mg/dL. Hiking tours such as the one organized for this study can improve quality of life/well-being without increasing diabetes distress and are considered relatively safe for T2DM patients, even for those being treated with insulin.

Abstract
The assessment and management of patient-reported outcomes (PROs) is considered secondary to that of cardiometabolic outcomes. When assessed, health-related quality of life (HRQOL), a PRO, can yield pertinent information that cannot be obtained from cardiometabolic assessments. For instance, physical and mental distress can be quantified and treated. Moreover, treatment convenience and satisfaction can be gaged. Behavioral modification, bariatric surgery, and pharmacotherapy can improve PROs. Typically, HRQOL is responsive to changes in weight. Specifically, weight loss and weight gain are associated with positive and negative changes in quality of life, respectively. In addition, patient satisfaction can be influenced by glycemic control. Therefore, hypoglycemia and hyperglycemic episodes can negatively affect patient satisfaction. When managing type 2 diabetes (T2D), it is important to consider how therapies impact PROs. Generally, changes in clinical outcomes mirror changes in PROs. To best manage T2D, integrating the assessment of PROs with clinical outcomes is needed.

Abstract
This study aimed to compare the effect of 16-weeks of combining aerobic and strength training with a linear increase or fixed intensity on the health-related quality of life (HRQoL) of obese adults. This single-blinded clinical trial involved adults with obesity (BMI ≥ 30 kg/m2), randomized into control (CG), fixed intensity (FG), or linear increase (LG) groups. The FG and LG performed 16 weeks of combined (aerobic + strength) training for 60 min, three times a week. The FG performed aerobic exercises between 50 and 59% of the heart rate reserve (HRres) and strength at 10–12 maximum repetitions (RM). The LG started with 40–49% of HRres and 12–14 RM and progressively increased the intensity (50–59% and 10–12 RM; 60–69% and 8–10 RM). The HRQoL was assessed using the SF-36 questionnaire. Generalized estimation equations and mean differences (∆) were used. Of the 69 participants (23 per group), 36 completed the intervention (CG = 13, FG = 9, and LG = 14). A significant difference was observed in the time of the physical function, with superiority in the training groups (CG: ∆ = 1.2 vs. FG and LG, respectively: ∆ = 10.0). The mental health component and mental health domain showed significant differences for the FG (∆ = 30.2 and ∆ = 23.1, respectively). In conclusion, the combined training improved physical functioning. Specifically, fixed-intensity training effectively enhanced mental health indicators.

Abstract
Patient-centered communication (PCC) by healthcare professionals can contribute to enacting and facilitating patients' self-management of chronic health conditions. This study investigates the emerging patterns of PCC that occur in an mHealth-based diabetes prevention program for older adults. The analysis of user-coach communication data during the 16-week period of the program revealed four PCC strategies employed by coaches: (a) triggering reflections on users' routinized habits, (b) jointly determining a measurable health goal, (c) facilitating self-evaluations on recent behavior change, and (d) tailoring programs to adapt to users' lifestyle and health status. To advance these strategies, coaches utilized various mHealth features that helped them (a) engage in data-driven coaching, (b) increase situational awareness of users' health conditions and routines, (c) provide continuous support to users through regular and spontaneous in-app chats, and (d) foster user autonomy and engagement. The findings extend implications for developing technology-enabled healthcare practice to enhance self-management of chronic illness.

Metformin alters skeletal muscle transcriptome adaptations to resistance training in older adults. Aging (Albany NY) 2020; 12:19852-19866.

Abstract
Evidence from clinical trials and observational studies suggests that both progressive resistance exercise training (PRT) and metformin delay a variety of age-related morbidities. Previously, we completed a clinical trial testing the effects of 14 weeks of PRT + metformin (metPRT) compared to PRT with placebo (plaPRT) on muscle hypertrophy in older adults. We found that metformin blunted PRT-induced muscle hypertrophic response. To understand potential mechanisms underlying the inhibitory effect of metformin on PRT, we analyzed the muscle transcriptome in 23 metPRT and 24 plaPRT participants. PRT significantly increased expression of genes involved in extracellular matrix remodeling pathways, and downregulated RNA processing pathways in both groups, however, metformin attenuated the number of differentially expressed genes within these pathways compared to plaPRT. Pathway analysis showed that genes unique to metPRT modulated aging-relevant pathways, such as cellular senescence and autophagy. Differentially expressed genes from baseline biopsies in older adults compared to resting muscle from young volunteers were reduced following PRT in plaPRT and were further reduced in metPRT. We suggest that although metformin may blunt pathways induced by PRT to promote muscle hypertrophy, adjunctive metformin during PRT may have beneficial effects on aging-associated pathways in muscle from older adults.

Abstract
Many older adults eat poorly balanced diets and are physically inactive, posing a risk to their cardiovascular and mental health. The benefits of healthful living extend beyond cardiovascular health and disease risk reduction such that physical activity has been shown to positively affect mood state. This was a cross-sectional investigation completed at three senior lunch program sites in Charlotte, NC to assess the status and relationship of nutrition, physical activity patterns, and mood state in older adults, prior to the center offering a new nutritional and physical activity intervention. Some significant relationships between cardiovascular indicators and mood were found.

Abstract
BACKGROUND Reports of sex differences in self-reported mood, sleep quality, daytime function, and excessive daytime sleepiness in people with obstructive sleep apnea (OSA) have been inconsistent. The purpose of this study was to investigate sex differences in these subjective sleep outcomes in participants with type 2 diabetes (T2D) either at high risk for OSA or diagnosed with OSA. METHODS Measures included OSA severity by apnea-hypopnea index (AHI) and self-reported questionnaires: Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale (ESS), functional outcomes of sleep quality questionnaire (FOSQ), and the profile of mood states (POMS). Relevant individual, social, and health determinants were included as covariates. RESULTS A total of 350 participants with T2D [Mean A1C 8.0% (SD ±1.8)] had mean age 56.5 (SD ±10.5) and were balanced by sex (51% men) and race (60% white, 40% non-white). Reports of sleep quality and daytime function were worse in women than in men (p <0.05), whereas men had more severe OSA than women (p <0.05). In fully adjusted models, there was no moderation by sex in the relations between AHI and the sleep outcome measures. AHI showed a significant association with ESS but not PSQI, FOSQ, or POMS. CONCLUSION In participants with T2D at high risk for or diagnosed with OSA, excessive daytime sleepiness was independently associated with OSA severity, but not self-reported sleep quality, daytime function, or mood. While women reported worse outcomes associated with sleep, these outcomes were not associated with OSA severity.

Abstract
Chronic diseases are the leading cause of death worldwide with increasing prevalence in all age groups, genders, and ethnicities. Most chronic disease deaths occur in middle-to low-income countries but are also a significant health problem in developed nations. Multiple chronic diseases now affect children and adolescents as well as adults. Being physically inactive is associated with increased chronic disease risk. Global societies are being negatively impacted by the increasing prevalence of chronic disease which is directly related to rising healthcare expenditures, workforce complications regarding attendance and productivity, military personnel recruitment, and academic success. However, increased physical activity (PA) and exercise are associated with reduced chronic disease risk. Most physiologic systems in the body benefit positively from PA and exercise by primary disease prevention and secondary disease prevention/treatment. The purpose of this brief review is to describe the significant global problem of chronic diseases for adults and children, and how PA and exercise can provide a non-invasive means for added prevention and treatment.

Abstract
CONTEXT The combination of two beneficial antidiabetes interventions, regular exercise and pharmaceuticals, is intuitively appealing. However, metformin, the most commonly prescribed diabetes medication, attenuates the favorable physiological adaptations to exercise; in turn, exercise may impede the action of metformin. OBJECTIVE We sought to determine the influence of an alternative diabetes treatment, sodium glucose cotransporter 2 (SGLT2) inhibition, on the response to endurance exercise training. DESIGN, PARTICIPANTS, AND INTERVENTION In a randomized, double-blind, repeated measures parallel design, 30 sedentary overweight and obese men and women were assigned to 12 weeks of supervised endurance exercise training, with daily ingestion of either a placebo or SGLT2 inhibitor (dapagliflozin: ≤10 mg/day). OUTCOME MEASUREMENTS AND RESULTS Endurance exercise training favorably modified body mass, body composition (dual-energy x-ray absorptiometry), peak oxygen uptake (graded exercise with indirect calorimetry), responses to standardized submaximal exercise (indirect calorimetry, heart rate, and blood lactate), and skeletal muscle (vastus lateralis) citrate synthase activity (main effects of exercise training, all P < 0.05); SGLT2 inhibition did not influence any of these physiological adaptations (exercise training × treatment interaction, all P > 0.05). However, after endurance exercise training, fasting blood glucose was greater with SGLT2 inhibition, and increased insulin sensitivity (oral glucose tolerance test/Matsuda index) was abrogated with SGLT2 inhibition (exercise training × treatment interaction, P < 0.01). CONCLUSION The efficacy of combining two beneficial antidiabetes interventions, regular endurance exercise and SGLT2 inhibition, was not supported. SGLT2 inhibition blunted endurance exercise training-induced improvements in insulin sensitivity, independent of effects on aerobic fitness or body composition.

Abstract
AIMS To assess whether aerobic or resistance training has greater benefits in non-physically active men with a long lasting type 1 diabetes. The effects of exercise were evaluated in terms of diabetes control and risk factors for cardiovascular complications. METHODS 21 male participants (mean age: 37 yrs, diabetes duration: 23 yrs, mean HbA1c: 7.4%) randomly assigned to 2 groups: 1-aerobic training (n = 10) and 2-resistance training (n = 11). All subjects participated in 60-min training sessions, either aerobic or resistance, twice a week for three months. At baseline and after 3 months: echocardiography, ECG and incremental exercise test, ECG and blood pressure monitoring, lipid profile, lactate and diabetes control parameters were assessed in all patients. RESULTS Baseline HbA1c was 7.44% in aerobic group and 7.36% in resistance group (p = 0.84). After 3 months there was no significant change in HbA1c value in any exercise group but a non-statistically significant downward trend was seen particularly in aerobic exercise group (p = 0.07) vs the resistance group (p = 0.15). There was no significant difference in body mass, risk of hypoglycemia and cardiovascular risk factors. CONCLUSIONS Both forms of exercise are safe in terms of glycemic control and cardiovascular risk factors in patients with quite well-controlled type 1 diabetes without advanced late complications.

The relationship between intensification of blood glucose-lowering therapies, health status and quality of life in type 2 diabetes: The Fremantle Diabetes Study Phase II. Diabetes Res Clin Pract 2018; 142:294-302. [PMID: 29879496 DOI: 10.1016/j.diabres.2018.05.047] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Revised: 05/25/2018] [Accepted: 05/30/2018] [Indexed: 10/14/2022]
Abstract
AIMS To determine whether therapeutic intensification in type 2 diabetes influences health status and quality of life (QoL). METHODS We studied 930 participants in the longitudinal observational Fremantle Diabetes Study Phase II (mean age 65.3 years, 53.8% males, median diabetes duration 8.0 years) with valid data from baseline assessment and two biennial reviews (4 years of follow-up) between 2008 and 2015. The main outcome measures were the Short Form-12 version 2 physical and mental health composite scores (PCS, MCS) and the average weighted impact (AWI) score from the Audit of Diabetes Dependent QoL. RESULTS There were reductions in PCS at Year 4 compared with baseline and Year 2 in patients on stable diet-based management (n = 160), oral glucose-lowering medication (OGLM; n = 387), and insulin with/without OGLM (n = 168; P < 0.05), but no statistically significant temporal changes in MCS/AWI. Insulin-treated patients had the lowest PCS, MCS and AWI compared to the other two subgroups at each time-point (P ≤ 0.012). In participants initiating OGLM (n = 84) or insulin (n = 85), there were no differences in PCS, MCS or AWI at the biennial assessments either side of these therapeutic changes (P ≥ 0.08). CONCLUSIONS These real-life data show that treatment intensification, including insulin initiation, does not impact adversely on patient well-being in community-based type 2 diabetes. Since insulin use at entry was associated with longer diabetes duration, worse glycaemic control, and a greater risk of chronic complications, the burden of disease rather than treatment modality appears the primary determinant of health status and QoL.

Oncotarget 2018; 9:7298-7311. [PMID: 29484111 PMCID: PMC5800903 DOI: 10.18632/oncotarget.23292] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2017] [Accepted: 12/08/2017] [Indexed: 02/03/2023] Open
Abstract
High-Fat-Diet (HFD)-induced obesity is a major contributor to heart and mobility premature aging and mortality in both Drosophila and humans. The dSir2 genes are closely related to aging, but there are few directed reports showing that whether HFD could inhibit the expression dSir2 genes. Endurance exercise can prevent fat accumulation and reverse HFD-induced cardiac dysfunction. Endurance also delays age-relate functional decline. It is unclear whether lifetime endurance exercise can combat lifetime HFD-induced heart and mobility premature aging, and relieve the harmful HFD-induced influence on the dSir2 gene and lifespan yet. In this study, flies are fed a HFD and trained from when they are 1 week old until they are 5 weeks old. Then, triacylglycerol levels, climbing index, cardiac function, lifespan, and dSir2 mRNA expressions are measured. We show that endurance exercise improves climbing capacity, cardiac contraction, and dSir2 expression, and it reduces body and heart triacylglycerol levels, heart fibrillation, and mortality in both HFD and aging flies. So, lifelong endurance exercise delays HFD-induced accelerated age-related locomotor impairment, cardiac dysfunction, death, and dSir2 expression decline, and prevents HFD-induced premature aging in Drosophila.

Impact of a lay-led home-based intervention programme on quality of life in community-dwelling pre-frail and frail older adults: a randomized controlled trial. BMC Geriatr 2017; 17:154. [PMID: 28724351 PMCID: PMC5517808 DOI: 10.1186/s12877-017-0548-7] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2017] [Accepted: 07/13/2017] [Indexed: 12/05/2022] Open
Abstract
BACKGROUND Due to the demographic ageing process and the increasing number of pre-frail and frail individuals, new lifestyle interventions to enhance the quality of life (QoL) in community-dwelling older adults are necessary. Therefore, we performed a randomised controlled trial (RCT) to compare effects of a lay-led home-based physical and nutritional intervention programme with social support alone on different QoL domains in community-dwelling pre-frail and frail older adults. METHODS In this analysis within a RCT (12 weeks), lay volunteers visited one-on-one pre-frail or frail older adults at home twice a week. Participants in the physical training and nutritional intervention (PTN) group performed six strength exercises and discussed main nutritional issues during each visit. The social support (SOSU) group received home visits twice a week for social exchanges. The QoL was assessed with the WHOQOL-BREF and the WHOQOL-OLD instruments. Analyses of covariance (ANCOVA) were used to examine differences between groups with baseline values as the covariate. Changes within groups were assessed with paired t-tests. RESULTS Eighty participants (n = 39 in the PTN group and n = 41 in the SOSU group) were included. No significant differences were found between the two groups except in past, present and future activities domain [β = 3.66 (95% confidence interval 0.13 to 7.18)] in favour of the PTN group. However, there was some evidence of greater within group improvements in the PTN group particularly in overall QoL, social relations and social participation. In the SOSU group, no significant effect was observed in any QoL domain. CONCLUSION A combination of a home-based physical and nutritional intervention was not more effective compared to social support alone, on QoL in community-dwelling pre-frail and frail older adults. However, the small but significant improvement within the PTN group suggests that a home-based physical and nutritional intervention delivered by volunteers may influence the QoL in a positive way. TRIAL REGISTRATION The study protocol was registered on 6 November 2013 at ClinicalTrials.gov (identifier: NCT01991639 ).
