Abstract Background: Exercise intervention and dietary supplementation are considered as approaches to manage obesity, as well as, metabolic syndrome (MetS). The aim of the present study was to evaluate the effect of sodium alginate supplementation with high intensity interval training (HIIT) or moderate-intensity continuous training (MICT) on serum levels of glucagon and glucagon-like peptide-1 (GLP-1) in women with MetS.Methods: This randomized controlled clinical trial was performed on 46 women with MetS. Participants were randomly divided to six groups including: 1) HIIT+ sodium alginate (HS, n=8); 2) HIIT+ placebo (HP, n=8); 3) MICT+ sodium alginate (MS, n=8); 4) MICT+ placebo (MP, n=8); 5) sodium alginate (S, n=7); and 6) control group (P, n=7). Sodium alginate were prescribed 1.5 gram alone or along with HIIT or MICT sessions (3 times per week). Anthropometric indices, glycemic profile, serum level of glucagon and GLP-1 were measured before and after 8 weeks intervention. Results: In HS, HP, MS, and MP groups the mean of weight (p=0.000), body mass index (p=0.001), fasting blood sugar (p=0.003), insulin (p=0.000), insulin resistance (p=0.043), and glucagon (p=0.011) decreased significantly, however GLP_1 (p=0/01) level increased significantly after intervention.Conclusion: Since HIIT and MICT with or without sodium alginate supplementation leads to improvement in anthropometric indices, glycemic profile, serum GLP-1 and glucagon levels, it can be stated that the training method of the present study is suitable for improving and reducing complications associated with MetS in women.Trial registration: IRCT20191116045457N1.

CONTEXT AND OBJECTIVE: Changes in metabolism have been reported in the majority of patients undergoing cancer treatment, and these are usually characterized by progressive change in body composition. The effects of aerobic exercise programs to combat the cancer and cancer treatment-related side effects, which include the negative changes in body composition, have been extensively reported in the literature. However, few resistance exercise intervention studies have hypothesized that breast cancer patients might benefit from this type of exercise. The purpose of this study was to determine whether exercise protocols that emphasize resistance training would change body composition and strength in breast cancer patients undergoing treatment. DESIGN AND SETTING: Randomized controlled trial, at the Campus Recreation Center and Rocky Mountain Cancer Rehabilitation Institute of the University of Northern Colorado, and the North Colorado Medical Center. METHODS: Twenty inactive breast cancer patients were randomly assigned to a 21-week exercise group (n = 10) or a control group (n = 10). The exercise group trained at low to moderate intensity for 60 minutes on two days/week. The primary outcome measurements included body composition (skinfold method) and muscle strength (one repetition maximum). RESULTS: Significant differences in lean body mass, body fat and strength (p = 0.004, p = 0.004, p = 0.025, respectively) were observed between the groups at the end of the study. CONCLUSION: The results suggest that exercise emphasizing resistance training promotes positive changes in body composition and strength in breast cancer patients undergoing treatment.

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are an ideal therapy for type 2 diabetes and, as of recently, for obesity. In contrast to visceral fat, subcutaneous fat appears to be protective against metabolic diseases. Here, we aimed to explore whether liraglutide, a GLP-1RA, could redistribute body fat via regulating lipid metabolism in different fat depots. After being fed a high-fat diet for 8 weeks, 50 male Wistar and Goto-Kakizaki rats were randomly divided into a normal control group, a diabetic control group, low- and high-dose liraglutide-treated groups and a diet-control group. Different doses of liraglutide (400 μg/kg/day or 1200 μg/kg/day) or an equal volume of normal saline were administered to the rats subcutaneously once a day for 12 weeks. Body composition and body fat deposition were measured by dual-energy X-ray absorptiometry and MRI. Isotope tracers were infused to explore lipid metabolism in different fat depots. Quantitative real-time PCR and Western blot analyses were conducted to evaluate the expression of adipose-related genes. The results showed that liraglutide decreased visceral fat and relatively increased subcutaneous fat. Lipogenesis was reduced in visceral white adipose tissue (WAT) but was elevated in subcutaneous WAT. Lipolysis was also attenuated, and fatty acid oxidation was enhanced. The mRNA expression levels of adipose-related genes in different tissues displayed similar trends after liraglutide treatment. In addition, the expression of browning-related genes was upregulated in subcutaneous WAT. Taken together, the results suggested that liraglutide potentially redistributes body fat and promotes browning remodeling in subcutaneous WAT to improve metabolic disorders.

Arteriovenous difference and tracer ([3-3H]glucose) techniques were used in 42-h-fasted conscious dogs to identify any insulin-like effects of intraportally administered glucagon-like peptide 1-(7–36)amide (GLP-1). Each study consisted of an equilibration, a basal, and three 90-min test periods (P1, P2, and P3) during which somatostatin, intraportal insulin (3-fold basal) and glucagon (basal), and peripheral glucose were infused. Saline was infused intraportally in P1. During P2 and P3, GLP-1 was infused intraportally at 0.9 and 5.1 pmol · kg−1 · min−1in eight dogs, at 10 and 20 pmol · kg−1 · min−1in seven dogs, and at 0 pmol · kg−1 · min−1in eight dogs (control group). Net hepatic glucose uptake was significantly enhanced during GLP-1 infusion at 20 pmol · kg−1 · min−1[21.8 vs. 13.4 μmol · kg−1 · min−1(control), P < 0.05]. Glucose utilization was significantly increased during infusion at 10 and 20 pmol · kg−1 · min−1[87.3 ± 8.3 and 105.3 ± 12.8, respectively, vs. 62.2 ± 5.3 and 74.7 ± 7.4 μmol · kg−1 · min−1(control), P < 0.05]. The glucose infusion rate required to maintain hyperglycemia was increased ( P < 0.05) during infusion of GLP-1 at 5.1, 10, and 20 pmol · kg−1 · min−1(22, 36, and 32%, respectively, greater than control). Nonhepatic glucose uptake increased significantly during delivery of GLP-1 at 5.1 and 10 pmol · kg−1 · min−1(25 and 46% greater than control) and tended ( P = 0.1) to increase during GLP-1 infusion at 20 pmol · kg−1 · min−1(24% greater than control). Intraportal infusion of GLP-1 at high physiological and pharmacological rates increased glucose disposal primarily in nonhepatic tissues.

BackgroundThis case–control study was conducted to investigate the relationship between serum nesfatin-1 levels and nutritional status and blood parameters in patients diagnosed with metabolic syndrome.MethodsThirty patients (case) diagnosed with metabolic syndrome according to National Cholesterol Education Program-Adult Treatment Panel III criteria were included. Thirty healthy subjects (control) matched with patients with metabolic syndrome in terms of age, gender and body mass index were included. Three-day food consumption records were obtained. Anthropometric indices were measured and body composition was determined by bioelectrical impedance method. Biochemical parameters and serum nesfatin-1 levels were measured after 8 hours of fasting.ResultsSerum nesfatin-1 levels were 0.245±0.272 ng/mL in the case group and 0.528±0.987 ng/mL in the control group (p>0.05). There was a positive significant correlation between serum nesfatin-1 levels and body weight, waist and hip circumferences in the case group (p<0.05). Each unit increase in hip circumference measurement affects the levels of nesfatin by 0.014 times. In the control group, there was a positive significant correlation between body weight and serum nesfatin-1 levels (p<0.05). A significant correlation was detected between HbA1c and serum nesfatin-1 levels in the case group (p<0.05). A significant relationship was detected between dietary fibre intake and the serum nesfatin-1 levels in the case group (p<0.05).ConclusionsAnthropometric indices and blood parameters were correlated with serum nesfatin-1 levels in patients with metabolic syndrome. More clinical trials may be performed to establish the relationship between serum nesfatin-1 levels and nutritional status.

ObjectiveWe aimed to examine whether eHealth interventions can effectively improve anthropometric and biochemical indicators of patients with metabolic syndrome (MetS).DesignSystematic review and meta-analysis.MethodsPubMed, the Web of Science, Embase, Medline, CINAHL, PsycINFO, the Cochrane Library, the Chinese National Knowledge Infrastructure, the Wanfang and Weipu databases were comprehensively searched for papers that were published from database inception to May 2019. Articles were included if the participants were metabolic syndrome (MetS) patients, the participants received eHealth interventions, the participants in the control group received usual care or were wait listed, the outcomes included anthropometric and biochemical indicators of MetS, and the study was a randomised controlled trial (RCT) or a controlled clinical trial (CCT). The Quality Assessment Tool for Quantitative Studies was used to assess the methodological quality of the included articles. The meta-analysis was conducted using Review Manager V.5.3 software.ResultsIn our review, seven RCTs and two CCTs comprising 935 MetS participants met the inclusion criteria. The results of the meta-analysis revealed that eHealth interventions resulted in significant improvements in body mass index (standardised mean difference (SMD)=−0.36, 95% CI (−0.61 to −0.10), p<0.01), waist circumference (SMD=−0.47, 95% CI (−0.84 to −0.09), p=0.01) and systolic blood pressure(SMD=−0.35, 95% CI (−0.66 to −0.04), p=0.03) compared with the respective outcomes associated with the usual care or wait-listed groups. Based on the included studies, we found significant effects of the eHealth interventions on body weight. However, we did not find significant positive effects of the eHealth interventions on other metabolic parameters.ConclusionsThe results indicated that eHealth interventions were beneficial for improving specific anthropometric outcomes, but did not affect biochemical indicators of MetS. Therefore, whether researchers adopt eHealth interventions should be based on the purpose of the study. More rigorous studies are needed to confirm these findings.

The purpose of this study was to examine the effects of a long-term community-based lifestyle intervention on the biochemical indicators and prevalence of metabolic syndrome among elderly adults. This was a randomized controlled trial in northern Taiwan from August 2013 to February 2015. Sixty-nine elderly adults participated in this study. There were three measurements. The experimental group participated in exercise and diet interventions. The control group participated in the exercise intervention. Repeated measurement and ANCOVA were performed to evaluate the effectiveness. After 18 months, body weight (1.06 kg), body mass index (1.21 kg/m2), waist circumference (3.32 cm), blood pressure, and prevalence (30.4%) of metabolic syndrome were significantly reduced in all subjects. There were significant differences in waist circumference and high-density lipoprotein cholesterol between the two groups. This intervention can lower the indicators and prevalence of metabolic syndrome. Exercise and diet interventions could promote further metabolic changes.

The incretin hormone glucagon-like peptide-1 (GLP-1) is an important insulin secretagogue and GLP-1 analogs are used for the treatment of type 2 diabetes. GLP-1 displays antiinflammatory and surfactant-releasing effects. Thus, we hypothesize that treatment with GLP-1 analogs will improve pulmonary function in a mouse model of obstructive lung disease. Female mice were sensitized with injected ovalbumin and treated with GLP-1 receptor (GLP-1R) agonists. Exacerbation was induced with inhalations of ovalbumin and lipopolysaccharide. Lung function was evaluated with a measurement of enhanced pause in a whole-body plethysmograph. mRNA levels of GLP-1R, surfactants (SFTPs), and a number of inflammatory markers were measured. GLP-1R was highly expressed in lung tissue. Mice treated with GLP-1R agonists had a noticeably better clinical appearance than the control group. Enhanced pause increased dramatically at day 17 in all control mice, but the increase was significantly less in the groups of GLP-1R agonist-treated mice (P &lt; .001). Survival proportions were significantly increased in GLP-1R agonist-treated mice (P &lt; .01). SFTPB and SFTPA were down-regulated and the expression of inflammatory cytokines were increased in mice with obstructive lung disease, but levels were largely unaffected by GLP-1R agonist treatment. These results show that GLP-1R agonists have potential therapeutic potential in the treatment of obstructive pulmonary diseases, such as chronic obstructive pulmonary disease, by decreasing the severity of acute exacerbations. The mechanism of action does not seem to be the modulation of inflammation and SFTP expression.

Objective The aim of this study was to investigate the effect of 8-week moderate-intensity and high-intensity accumulated exercise on insulin resistance in mice, compared with the moderate intensity continuous exercise with equal workload, which will provide an experimental reference for seeking a more reasonable and effective exercise program to break sedentary behavior and improve metabolic diseases such as IR. Methods Eighty 4-week-old C57BL/6J mice were randomly divided into normal diet group (group C) and high-fat diet group (group H), fed with different diet. At the 10th weekend, insulin resistance model was judged by OGTT curve (AUC) and fasting blood glucose. All mice with insulin resistance were randomly divided into four groups: IR control group (IC), IR moderate-intensity continuous exercise group (IE), IR moderate-intensity accumulated exercise group (IM), IR high-intensity accumulated exercise group (IH), retained normal diet control group (C), with 12 mice for each group. All groups were fed with normal feed. The three exercise-related group performed an 8-week’s treadmill exercise program with equal workload (involve preparation and relaxation activities,0°platform slope, 5 days/week). For IE group, mice run 50min continuously with the velocity of 11m/min. For IM group，mice exercised 12.5 min per session, total 4 sessions per day, with 3-hour’s interval and the velocity of 11m/min. The IH group performed an alike exercise program with IM group, except the running speed (19m/min) and exercise time (7.5min). On the 8th weekend of exercise, FBG, OCTT, FINS, HOME- IR, and ISI were tested for each groups. Results 1. Compared with group C, body weight, FBG and OGTT-AUC were significantly increased in group H (P<0.05 or P<0.01). 76% mice were induced to insulin resistance successfully.  2. Before and after exercise intervention of 8 weeks, there were no significant changes in body weight and OGTT-AUC, while the FBG was significantly increased in IC group (P<0.05). Body weight, FBG, and OGTT-AUC significantly decreased in IE group, IM group and IH group (P<0.05 or P<0.01). 3. After 8 weeks of exercise intervention, the FBG in the IE group, IM group, and IH group were significantly lower than that in C group (P<0.05 or P<0.01). Compared with the IC group, the FBG, FINS, OGTT-AUC, and HOME-IR in IM group, IH group and IE group were lower than those in the IC group (P<0.05 or P<0.01). Compared with the IE group, the body weight and HOME-IR index of IH group were significantly lower than those in IE group (P<0.01). Compared with IH group, the HOME-IR in IH group was lower than that in IM group (P<0.05); There was no significant difference between IM group and IE group. Conclusions 1. Chronic moderate-intensity continuous exercise, moderate-intensity accumulated exercise, and high-intensity accumulated exercise all can effectively improve the glucose metabolism and insulin resistance in IR mice. 2.Compared with moderate-intensity accumulated exercise and moderate-intensity continuous exercise, the high-intensity accumulated exercise with equal workload is more effective in reducing the body weight and improving insulin resistance in IR mice.

Background. During radiotherapy (RT), prostate cancer (PCa) patients very often report fatigue, which impairs functional capacity, psychological status, and quality of life (QoL). It is well known that physical exercise plays an important role in healthy adults, has positive role for immunological aspects and improves QoL in cancer patients. Previous studies have shown that physical exercise in cancer patients undergoing RT improves cardiac fitness, and QoL, however it is still not well known how physical exercise affects physical fitness and fatigue in PCa patients during RT. Therefore, the purpose of this study was to examine the effect of supervised physical exercise on the relationship between fatigue and physical endurance in high-risk PCa patients undergoing RT. Material and Methods This was a prospective, two-arm randomised controlled clinical trial. The study was performed in outpatients in the Greater Poland Cancer Centre. Population. Seventy-two high-risk PCa men were randomly allocated to two groups prior to undergoing RT. Thirty-six patients performed supervised moderate-intensity physical exercise (exercise group; EG) and the other 36 formed a control group that carried out normal daily physical activity (usual group; UG). The following parameters were assessed before and after RT: functional capacity, fatigue scores. Results. No significant differences existed between the study groups at pre-RT assessment. After RT, there was a significant improvement in functional capacity (p<0.05) and important smaller fatigue scores in EG. Conclusion. Regular, moderate-intensity physical exercise improves functional capacity and has positive influence on fatigue symptoms during RT in high-risk PCa patients. Therefore, this group of patients should conduct regular physical training during RT to decrease side effects of treatment.
