Hypertension is considered one of the risk factors for cardiovascular disease. Hypertension is a multifactorial condition in which arterial stiffness is one of its manifestations. Exercise is a nonpharmaceutical intervention, and it is known to induce cardiovascular benefits. The aim of this study was to evaluate if the mechanistic effect of high-intensity interval training (HIIT) would affect arterial stiffness parameters in sedentary obese hypertensive women. This study is a randomised controlled trial which enrolled sixty hypertensive women between the ages of 40 and 50 years. Participants were randomly assigned to one of two groups: 1) 12-week of high-intensity interval training or 2) a control group. Results show that HIIT has a beneficial effect on lowering arterial stiffness in obese hypertensive women. Furthermore, HIIT resulted in significant improvements in several metabolic parameters namely blood pressure, total cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, and triglycerides. Authors conclude that HIIT for 12 weeks reduces cardiometabolic risk factors and improves arterial stiffness indices in obese hypertensive women. Thus, HIIT should be included in the treatment of obese hypertensive women to reduce their risk of cardiovascular disease.
Abstract
OBJECTIVE High-intensity interval training (HIIT) has been linked to a lower risk of cardiovascular disease and mortality. The study's overarching goal is to evaluate the impact of HIIT on arterial stiffness in obese hypertensive women. PATIENTS AND METHODS Sixty obese hypertensive women aged between 40-50 years were randomized to group A (Intervention group, n = 30) or group B (Control group, n = 30). Intervention group received HIIT (4 minutes of cycling at 85-90% of peak HR interspersed with 3-minute active recovery time at 60 - 70% of peak HR, three times per week). Arteriovenous stiffness indicators, the augmentation index corrected for heart rate 75 (AIx@75HR), and oscillometric pulse wave velocity (o-PWV), as well as cardio-metabolic parameters, were assessed before and after 12 weeks of treatment. RESULTS Finding between-group analysis showed a significant difference in AIx@75HR (95% CI: -8.45 to 0.30) , o-PWV ( 95% CI: -1.14 to 0.15), total cholesterol, (95% CI: -31.25 to -1.12), HDL-cholesterol (95% CI: 8.92 to 0.94), LDL-cholesterol (95% CI: -25.35 to -0.06) , and triglycerides (95% CI: -53.58 to -2.51). CONCLUSIONS High-intensity interval training for 12 weeks has a favorable effect on arterial stiffness in obese hypertensive women and lowers associated cardio-metabolic risk factors.

Intermittent fasting (IF) involves an alternation of abstinence and consumption of food and caloric beverages over a cycle of hours to days. Time-restricted feeding (in animals) or eating (TRE in humans) is a form of IF that entails restricting eating within a window of 4 to 12 hours per 24-hour cycle and prolonging the time spent in the fasted state to realign eating-fasting patterns with circadian rhythms. The aim of this study was to explore the impact of a 6-month randomised controlled trial of TRE versus standard dietary advice (SDA, active control arm) on bone metabolism and health in a population with at least one component of the metabolic syndrome. This study is a secondary analysis of an open-label 6-month randomised controlled trial in which participants who ate within a time interval > 14 hours per 24-hour cycle (n=54) were randomised to TRE or SDA (active control) with a 1:1 allocation ratio. A total of 42 participants (76% women) with available bone turnover markers and/or bone mass measurements were included in this study. Results show that there weren’t any detrimental effects on bone health outcomes i.e. bone metabolism or bone loss after 6 months of TRE. Additionally, weight loss following a period of TRE might be associated with small bone-sparing effects compared with SDA. Authors conclude that future studies of longer duration (>6 months) assessing multiple bone phenotypes are required in order to confirm the study’s findings and explore the effects of various TRE regimens particularly among individuals at risk for bone fragility such as postmenopausal women and the elderly.
Abstract
OBJECTIVE This study explored the impact of time-restricted eating (TRE) versus standard dietary advice (SDA) on bone health. METHODS Adults with ≥1 component of metabolic syndrome were randomized to TRE (ad libitum eating within 12 hours) or SDA (food pyramid brochure). Bone turnover markers and bone mineral content/density by dual energy x-ray absorptiometry were assessed at baseline and 6-month follow-up. Statistical analyses were performed in the total population and by weight loss response. RESULTS In the total population (n = 42, 76% women, median age 47 years [IQR: 31-52]), there were no between-group differences (TRE vs. SDA) in any bone parameter. Among weight loss responders (≥0.6 kg weight loss), the bone resorption marker β-carboxyterminal telopeptide of type I collagen tended to decrease after TRE but increase after SDA (between-group differences p = 0.041), whereas changes in the bone formation marker procollagen type I N-propeptide did not differ between groups. Total body bone mineral content decreased after SDA (p = 0.028) but remained unchanged after TRE (p = 0.31) in weight loss responders (between-group differences p = 0.028). Among nonresponders (<0.6 kg weight loss), there were no between-group differences in bone outcomes. CONCLUSIONS TRE had no detrimental impact on bone health, whereas, when weight loss occurred, it was associated with some bone-sparing effects compared with SDA.

Metabolic syndrome (MetS) is a cluster of metabolic disorders such as hyperlipidaemia, hypertension, hyperglycaemia, insulin resistance, and abdominal obesity. MetS is associated with cardiovascular disease (CVD), type 2 diabetes mellitus and non-alcoholic fatty liver disease. The aim of this study was to investigate the effects of curcumin and/or coenzyme Q10 supplementation on metabolic syndrome components in subjects with MetS. This study is a 2×2 factorial, randomised, double-blinded, placebo-controlled study which was conducted for 12 weeks. Eighty-eight subjects were randomly assigned into four groups. All subjects completed the trial. Results show that curcumin supplementation improves lipid profile, but it does not have any effect on body composition, hypertension and fasting plasma glucose. However, supplementation with coenzyme Q10 as well as curcumin plus coenzyme Q10 did not show any significant effects on lipid profile, body composition, hypertension and fasting plasma glucose. Authors conclude that curcumin supplementation (especially by its effects on dyslipidaemia) is more effective than coenzyme Q10 as well as the combination of curcumin and coenzyme Q10 in the management of MetS. However, curcumin, coenzyme Q10 and their combination have no effect on body composition, hypertension and glycaemic control.
Abstract
BACKGROUND Metabolic syndrome (MetS) as a cluster of conditions including hyperlipidemia, hypertension, hyperglycemia, insulin resistance, and abdominal obesity is linked to cardiovascular diseases and type 2 diabetes. Evidence suggested that intake of curcumin and coenzyme Q10 may have therapeutic effects in the management of MetS. AIMS We investigated the effects of curcumin and/or coenzyme Q10 supplementation on metabolic syndrome components including systolic blood pressure (SBP), diastolic blood pressure (DBP), waist circumference (WC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-c) and fasting plasma glucose (FPG) as primary outcomes, and total cholesterol (TC), low density lipoprotein-cholesterol (LDL-c) and body mass index (BMI) as secondary outcomes in subjects with MetS. METHODS In this 2 × 2 factorial, randomized, double-blinded, placebo-controlled study, 88 subjects with MetS were randomly assigned into four groups including curcumin plus placebo (CP), or coenzyme Q10 plus placebo (QP), or curcumin plus coenzyme Q10 (CQ), or double placebo (DP) for 12 weeks. RESULTS The CP group compared with the three other groups showed a significant reduction in HDL-c (P = 0.001), TG (P < 0.001), TC (P < 0.001), and LDL-c (P < 0.001). No significant differences were seen between the four groups in terms of SBP, DBP, FPG, WC, BMI and weight. CONCLUSION Curcumin improved dyslipidemia, but had no effect on body composition, hypertension and glycemic control. Furthermore, coenzyme Q10 as well as the combination of curcumin and coenzyme Q10 showed no therapeutic effects in subjects with MetS. The trial was registered on 09/21/2018 at the Iranian clinical trials website (IRCT20180201038585N2), URL: https://www.irct.ir/trial/32518 .

Plain language summary
The hormone irisin is a myokine and is released into the blood from skeletal muscle after exercise. The literature indicates that coconut oil increases the metabolic rate, supports weight loss, and helps to create a feeling of satiety. Hormone irisin was found to play an important role in the pathophysiology of chronic diseases and in exercise. The aims of this study were to determine whether (a) irisin hormone is an important marker in the pathophysiology of obesity, (b) the effect of coconut oil is related to irisin, and (c) coconut oil is suitable for routine use in the diet treatment of obesity. This study is a randomized controlled study adopting two-phase cross-sectional design. All groups in the study consisted of adult individuals between the ages of 19–30 with a body mass index level of 25 kg/m2 − 29.5 kg/m2. Thirteen males (29.5%) and 31 females (70.5%) participated in the study. Results show that coconut oil had no effect on anthropometric measurements. However, coconut oil was found to be associated with the hormone irisin. Both phases of the study revealed that coconut oil reduced the level of hormone irisin in individuals with overweight. Authors conclude that multidisciplinary treatment of individuals with mild obesity should be carried out correctly. Furthermore, dietary therapy should be applied based on evidence in line with the recommendations of national and international guidelines.
Abstract
AIM: This study aimed to discover the effects of coconut oil intake and diet therapy on anthropometric measurements, biochemical findings and irisin levels in overweight individuals. MATERIALS AND METHODS Overweight individuals (n = 44, 19-30 years) without any chronic disease were included. In this randomized controlled crossover study, the participants were divided into two groups (Group 1: 23 people, Group 2: 21 people). In the first phase, Group 1 received diet therapy to lose 0.5-1 kg of weight per week and 20 mL of coconut oil/day, while Group 2 only received diet therapy. In the second phase, Group 1 received diet therapy while Group 2 received diet therapy and 20 mL of coconut oil/day. Anthropometric measurements were taken four times. Irisin was measured four times by enzyme-linked immunosorbent (ELISA) method and other biochemical findings were measured twice. Statistical analysis was made on SPSS 20. RESULTS The irisin level decreased significantly when the participants only took coconut oil (p ≤ 0.05). There was a significant decrease in the participants' body weight, body mass index (BMI) level and body fat percentage (p ≤ 0.01). Insulin, total cholesterol, low density lipoproteins (LDL) cholesterol, and triglyceride (TG) levels of all participants decreased significantly (p ≤ 0.05). There was no significant difference in irisin level due to body weight loss (p ≤ 0.05); coconut oil provided a significant decrease in irisin level (p ≤ 0.05). CONCLUSION Diet therapy and weight loss did not have an effect on irisin level, but coconut oil alone was found to reduce irisin level. Coconut oil had no impact on anthropometric and biochemical findings.

Plain language summary
The metabolic syndrome (MetS) is a condition characterized by the presence of at least three cardiovascular risk factors, such as abdominal obesity, hypertension, insulin resistance, and dyslipidaemia. The aim of this study was to assess effects of fasting followed by the Mind-Body Medicine in Integrative and Complementary Medicine (MICOM) lifestyle modification intervention in patients with MetS on patient-reported outcomes, compared to a lifestyle modification intervention only. This study is a single-blind, bicentre, randomized controlled study. Patients (n=145) were randomly assigned in a 1:1 ratio into one of the 2 groups: fasting and lifestyle modification or the lifestyle modification. They started with 2 vegan days (max. 1200 kcal/day), followed by 5 days of fasting (max. 350 kcal/day), and a stepwise reintroduction of food. Then they participated in the 10-week MICOM comprehensive multimodal lifestyle modification intervention with weekly 6-h sessions. Results show that after the multimodal lifestyle modification intervention, there were improvements for all outcome measures, namely quality of life, anxiety, depression, stress, mood as well as self-efficacy, mindfulness, and self-compassion, which persisted at the follow-up after 24 weeks. Authors conclude that their findings show beneficial and clinically relevant effects of fasting and intensified lifestyle modification on quality of life and psychological parameters.

Summary Review:
Metabolic syndrome (MetS) is a condition characterised by the presence of at least three cardiovascular risk factors such as abdominal obesity, hypertension, insulin resistance, and dyslipidemia.
The authors refer to epidemiological studies that have identified the role of psychological risk factors such as psychosocial stress, depression and anxiety in patients with MetS and cardiovascular disease.
This single-blind, bi-centre RCT assessed the effects of fasting followed by a comprehensive lifestyle modification program MICOM (Mind-Body Medicine in Integrative and Complementary Medicine) in 145 participants with Metabolic Syndrome (MetS) (62.8% women; 59.7 ± 9.3 years) randomised to:
1. 5-day fasting followed by 10 weeks of lifestyle modification (F + LM; modified DASH diet, exercise, mindfulness; n = 73) or
2. 10 weeks of lifestyle modification only (LM; n = 72)
The study duration was 24 weeks occurring from April 2014 to December 2014, with the last follow-up assessment in December 2015. 73 Participants were randomised into an F + LM group and 72 participants into an LM group between the ages of 59 and 60.
Outcomes were assessed at weeks 0, 1, 12, and 24, for quality of life (Short-Form 36 Health Survey Questionnaire, SF-36), anxiety/depression (Hospital Anxiety and Depression Scale, HADS), stress (Cohen Perceived Stress Scale, CPSS), mood (Profile of Mood States, POMS), self-efficacy (General Self-Efficacy Scale, GSE), mindfulness (Mindfulness Attention Awareness Scale, MAAS), and self-compassion (Self-Compassion Scale, SCS).
At week 1, POMS depression and fatigue scores were significantly lower in F + LM compared to LM. At week 12, most self-report outcomes improved in both groups—only POMS vigour was significantly higher in F + LM than in LM. Most of the beneficial effects within the groups persisted at week 24.
Clinical practice applications:
This randomised controlled trial highlights fasting-induced mood-modulating effects in the short term (<24 months).
LM induced several positive effects on quality of life and psychological parameters in participants with MetS.
The compliance rate for this study was good and there were no adverse effects reported suggesting a potentially effective lifestyle modification intervention for adults with metabolic syndrome.
The authors did note the extent to which participants adhered to the program by using stress reduction techniques at home was not assessed.
Considerations for future research:
MBM lifestyle modification intervention led to an improvement of self-efficacy, mindfulness, and self-compassion.
Further studies to explore explanatory models for the effects of MBM are needed.
Mediating variables on mindfulness, self-efficacy, and compassion, and the effects on physical and psychological parameters, need to be examined more closely.
Future studies could use condition-specific questionnaires in addition to generic ones, which have previously been used to facilitate the comparison of the study results with those in the population.
Abstract
Lifestyle interventions can have a positive impact on quality of life and psychological parameters in patients with metabolic syndrome (MetS).

Plain language summary
Obesity, dyslipidaemia, and metabolic syndrome are major risk factors for cardiovascular disease, however, effect of thyroid dysfunction on dyslipidaemia and cardiovascular disease is largely unknown. This study used mendelian randomisation (MR), where a genetic variant is used as an instrumental variable to detect the causal effects of exposure to disease. This study used two sample MR analyses to find out whether clinical thyroid function measures show a causal relationship with the changes in lipid levels. The results showed a significant association between the elevated thyrotropin (TSH) level and increased total cholesterol. Also, there was a significant correlation between the free triiodothyronine (FT3): free thyroxine (FT4) ratio and total cholesterol and low-density lipoprotein (LDL). Further robust studies are required to confirm the results and investigate the causal effect of thyroid hormone dysregulation and cardiometabolic diseases due to the limitations of this study. However, healthcare professionals can use the results of this study to understand the importance of the pituitary-thyroid-cardiac axis in lipid metabolism and its impact on cardiometabolic health.
Abstract
BACKGROUND Thyroid dysfunction is associated with cardiovascular diseases. However, the role of thyroid function in lipid metabolism remains partly unknown. The present study aimed to investigate the causal association between thyroid function and serum lipid metabolism via a genetic analysis termed Mendelian randomization (MR). METHODS The MR approach uses a genetic variant as the instrumental variable in epidemiological studies to mimic a randomized controlled trial. A two-sample MR was performed to assess the causal association, using summary statistics from the Atrial Fibrillation Genetics Consortium (n = 537,409) and the Global Lipids Genetics Consortium (n = 188,577). The clinical measures of thyroid function include thyrotropin (TSH), free triiodothyronine (FT3) and free thyroxine (FT4) levels, FT3:FT4 ratio and concentration of thyroid peroxidase antibodies (TPOAb). The serum lipid metabolism traits include total cholesterol (TC) and triglycerides, high-density lipoprotein, and low-density lipoprotein (LDL) levels. The MR estimate and MR inverse variance-weighted method were used to assess the association between thyroid function and serum lipid metabolism. RESULTS The results demonstrated that increased TSH levels were significantly associated with higher TC (β = 0.052, P = 0.002) and LDL (β = 0.041, P = 0.018) levels. In addition, the FT3:FT4 ratio was significantly associated with TC (β = 0.240, P = 0.033) and LDL (β = 0.025, P = 0.027) levels. However, no significant differences were observed between genetically predicted FT4 and TPOAb and serum lipids. CONCLUSION Taken together, the results of the present study suggest an association between thyroid function and serum lipid metabolism, highlighting the importance of the pituitary-thyroid-cardiac axis in dyslipidemia susceptibility.

Menopause may increase risk for chronic diseases such as obesity, osteoporosis and type 2 diabetes. Interventions to limit menopausal changes such as diet and exercise may improve outcomes. Resistance training and polyunsaturated fats may increase muscle production, however previous studies in postmenopausal women have had mixed outcomes. Therefore this randomised placebo control trial of 124 postmenopausal women aimed to determine if a polyunsaturated fat rich fish oil in combination with resistance training or alone for 16 weeks could affect overweight and obese postmenopausal women. The results showed no combined effect of resistance training and fish oil on body composition, muscle strength, blood pressure, lipids, or blood sugar balance. The resistance training group maintained bone density, increased muscle mass, decreased fat mass and increased blood sugar balance. The fish oil group showed lower blood pressure, lowered triglycerides, and improved muscle quality in lower limbs. It was concluded that resistance training improved body composition, bone density and blood sugar balance and fish oil improved heart health in postmenopausal women. This study could be used by healthcare professionals to recommend fish oil and resistance training to improve all aspects of physiological changes associated with menopause.
Abstract
Resistance training (RT) and n-3 polyunsaturated fatty acids (n-3 PUFA) supplementation have emerged as strategies to improve muscle function in older adults. Overweight/obese postmenopausal women (55-70 years) were randomly allocated to one of four experimental groups, receiving placebo (olive oil) or docosahexaenoic acid (DHA)-rich n-3 PUFA supplementation alone or in combination with a supervised RT-program for 16 weeks. At baseline and at end of the trial, body composition, anthropometrical measures, blood pressure and serum glucose and lipid biomarkers were analyzed. Oral glucose tolerance tests (OGTT) and strength tests were also performed. All groups exhibit a similar moderate reduction in body weight and fat mass, but the RT-groups maintained bone mineral content, increased upper limbs lean mass, decreased lower limbs fat mass, and increased muscle strength and quality compared to untrained-groups. The RT-program also improved glucose tolerance (lowering the OGTT incremental area under the curve). The DHA-rich supplementation lowered diastolic blood pressure and circulating triglycerides and increased muscle quality in lower limbs. In conclusion, 16-week RT-program improved segmented body composition, bone mineral content, and glucose tolerance, while the DHA-rich supplement had beneficial effects on cardiovascular health markers in overweight/obese postmenopausal women. No synergistic effects were observed for DHA supplementation and RT-program combination.

Multicomponent interventions consisting of dietary modification, physical activity, behavioural therapy, and education have shown to improve body mass index, blood pressure, and lipids profile. The Obemat2.0 trail was designed and conducted to implement and to test the efficacy of a structured multicomponent motivational therapy to treat childhood obesity. The study is a randomised clustered clinical trial with a treatment on children with obesity lasting 12 months. The study had two arms: a control group and an intervention group. The recruitment started in June 2016 and the fieldwork is expected to end in June 2019. The study results will show whether a multicomponent program, including a bundle of motivational strategies conducted in primary centres by therapists with 12h of specific training could be more effective than usual care. Authors expect this clinical trial to open a window of opportunity to support professionals at the primary care level to treat childhood obesity.
Abstract
The primary aim of the Obemat2.0 trial was to evaluate the efficacy of a multicomponent motivational program for the treatment of childhood obesity, coordinated between primary care and hospital specialized services, compared to the usual intervention performed in primary care. This was a cluster randomized clinical trial conducted in Spain, with two intervention arms: motivational intervention group vs. usual care group (as control), including 167 participants in each. The motivational intervention consisted of motivational interviewing, educational materials, use of an eHealth physical activity monitor and three group-based sessions. The primary outcome was body mass index (BMI) z score increments before and after the 12 (+3) months of intervention. Secondary outcomes (pre-post intervention) were: adherence to treatment, waist circumference (cm), fat mass index (z score), fat free mass index (z score), total body water (kg), bone mineral density (z score), blood lipids profile, glucose metabolism, and psychosocial problems. Other assessments (pre and post-intervention) were: sociodemographic information, physical activity, sedentary activity, neuropsychological testing, perception of body image, quality of the diet, food frequency consumption and foods available at home. The results of this clinical trial could open a window of opportunity to support professionals at the primary care to treat childhood obesity. The clinicaltrials.gov identifier was NCT02889406.

National Institutes of Health define erectile dysfunction as a persistent difficulty achieving and maintaining an erection sufficient for satisfactory sexual intercourse. The main aim of the study was to explore the effects of nuts supplementation on erectile function determined by the International Index of Erectile Function and the endothelial (inner lining of blood vessels) function. The study is a randomised controlled, two-interventions parallel, clinical trial conducted in healthy males who reported a Western-style diet. The 119 participants were randomly assigned to one of the two interventions. Results indicate that adding 60 g/d of mixed raw nuts to a Western-style diet for 14-wk improved the auto-reported orgasmic function and sexual desire parameters in a group of healthy reproductive-aged participants compared with an age-matched control group. Authors conclude that compliance with a healthy diet supplemented with mixed nuts may help to improve erectile and sexual desire.
Abstract
Lifestyle risk factors for erectile and sexual function include smoking, excessive alcohol consumption, lack of physical activity, psychological stress, and adherence to unhealthy diets. In the present study, we evaluated the effects of mixed nuts supplementation on erectile and sexual function. Eighty-three healthy male aged 18-35 with erectile function assessment were included in this FERTINUTS study sub-analysis; a 14-week randomized, controlled, parallel feeding trial. Participants were allocated to (1) the usual Western-style diet enriched with 60 g/day of a mixture of nuts (nut group; n = 43), or (2) the usual Western-style diet avoiding nuts (control group; n = 40). At baseline and the end of the intervention, participants answered 15 questions contained in the validated International Index of Erectile Function (IIEF), and peripheral levels of nitric oxide (NO) and E-selectin were measured, as surrogated markers of erectile endothelial function. Anthropometrical characteristics, and seminogram and blood biochemical parameters did not differ between intervention groups at baseline. Compared to the control group, a significant increase in the orgasmic function (p-value = 0.037) and sexual desire (p-value = 0.040) was observed during the nut intervention. No significant differences in changes between groups were shown in peripheral concentrations of NO and E-selectin. Including nuts in a regular diet significantly improved auto-reported orgasmic function and sexual desire.

Metabolic syndrome is a cluster of conditions related to cardiovascular disorders risk factors such as blood pressure, dyslipidaemia, hyperglycaemia, excess body fat around the waist and insulin resistance. The aim of this study was to assess the effects of a gluten-free diet on components of metabolic syndrome in patients diagnosed with metabolic syndrome. The study is a randomised control trial that recruited fifty subjects diagnosed with metabolic syndrome. Subjects were block randomised by gender into control and gluten-free diet groups. Results showed that a gluten-free diet induces significant reduction in waist circumference in comparison to control diet. Reduction in waist circumference without significant reduction in body weight may indicate preferential loss of abdominal fat. Furthermore, results indicate that a gluten-free diet improved glucose tolerance. Authors conclude that a gluten-free diet significantly improved some key features of metabolic syndrome including blood glucose and serum triglycerides.
Abstract
Background: This study aimed to assess the effects of Gluten free diet (GFD) on components of metabolic syndrome (MES). Materials and Methods: In this randomized clinical trial, 50 subjects diagnosed with MES were randomly divided into two groups (n=25). The first group received a GFD and the second group continued their regular diet. Biochemical markers of MES and blood pressure were measured before and after 8-week intervention. Results: Forty five subjects completed the study. A post-hoc comparison of the groups showed no effects of the GFD and control diet on LDL cholesterol, total cholesterol, fasting insulin, HOMA-IR, systolic and diastolic blood pressure levels. The GFD reduced fasting blood glucose, waist circumference (WC) and serum triglyceride concentration significantly compared with the control diet (p<0.05). Conclusion: Short-term GFD reduced WC and improved glycemic control and Triglyceride level in subjects with the metabolic syndrome.
