Abstract
IMPORTANCE The universal call to action for healthier and more sustainable dietary choices is the framework of the United Nations's Sustainable Development Goals. The Atlantic diet, originating from the northwest of the Iberian Peninsula, represents an example of a traditional diet that aligns with these principles. OBJECTIVE To explore a 6-month intervention based on the Atlantic diet's effects on metabolic and environmental health, assessing metabolic syndrome (MetS) incidence and the carbon footprint. DESIGN, SETTING, AND PARTICIPANTS The Galician Atlantic Diet study was a 6-month randomized clinical trial designed to assess the effects of this regional traditional diet on families' eating habits. The study was conducted from March 3, 2014, to May 29, 2015, at a local primary health care center in the rural town of A Estrada in northwestern Spain and involved a multisectoral collaboration. Families were randomly selected from National Health System records and randomized 1:1 to an intervention or control group. This secondary analysis of the trial findings was performed between March 24, 2021, and November 7, 2023. INTERVENTIONS Over 6 months, families in the intervention group received educational sessions, cooking classes, written supporting material, and foods characteristic of the Atlantic diet, whereas those randomized to the control group continued with their habitual lifestyle. MAIN OUTCOMES AND MEASURES The main outcomes were MetS incidence, defined per National Cholesterol Education Program Adult Treatment Panel III guidelines, and carbon footprint emissions as an environmental metric using life cycle assessment with daily dietary intake as the functional unit. RESULTS Initially, 250 families were randomized (574 participants; mean [SD] age, 46.8 [15.7] years; 231 males [40.2%] and 343 females [59.8%]). The intervention group included 126 families (287 participants) and the control group, 124 families (287 participants). Ultimately, 231 families completed the trial. The intervention significantly reduced the risk of incident cases of MetS (rate ratio, 0.32; 95% CI, 0.13-0.79) and had fewer MetS components (proportional odds ratio, 0.58; 95% CI, 0.42-0.82) compared with the control condition. The intervention group did not have a significantly reduced environmental impact in terms of carbon footprint emissions compared with the control group (-0.17 [95% CI, -0.46 to 0.12] kg CO2 equivalents/person/d). CONCLUSIONS AND RELEVANCE These findings provide important evidence that a family-focused dietary intervention based on a traditional diet can reduce the risk of incident MetS. Further research is needed to understand the underlying mechanisms and determine the generalizability to other populations, taking into account regional cultural and dietary variations.

Abstract
BACKGROUND In response to the serious lack of physical activity among young adults, recent attempts have been made to encourage young people to exercise through exercise video distribution. However, merely distributing videos does not lead to improved physical activity levels. Metaverse space, which enables web-based interaction through avatars, allows users to watch exercise videos in the same space as other avatars. OBJECTIVE This study explored whether exercise video distribution using metaverse space is effective in improving physical activity levels, along with mental health and locomotive function, among young people. METHODS In this parallel-group randomized controlled trial participants were recruited using printed poster displays. A total of 48 young adults aged between 18 and 30 years were assigned to 3 groups of 16 each: the metaverse, YouTube, and control group. To encourage exercise, the metaverse group was given an exercise video each week with a load of around 4-8 metabolic equivalents of tasks (METs) for 8 videos delivered in the metaverse space. The YouTube group was sent a URL on YouTube every week to view exercise videos with the same content as the metaverse group. The control group was given no special instructions. The intervention period was 8 weeks. Pre- and postintervention physical activity, well-being, locomotive syndrome risk tests, and social capital were measured. Although this study was not blinded to the participants, the measurers did not know to which group the participants belonged. Mixed model repeated-measures analyses and a post hoc Wilcoxon signed rank sum test were performed to detect the effects of the intervention in all groups. RESULTS The results of the mixed model repeated-measures analyses showed a significant interaction between groups and before and after the intervention for total physical activity (metaverse group: pre 737.1, SD 609.5 METs/week, post 1575.4, SD 1071.8 METs/week; YouTube group: pre 661.7, SD 710.7 METs/week, post 911.9, SD 1103.3 METs/week; and control group: pre 930.6, SD 665.1 METs/week, post 844.7, SD 701.8 METs/week; P=.04) but none for the indicators of well-being (P=.40), locomotive function scale (P=.17), and social capital (P=.23). A post hoc test showed a significant increase in physical activity in the metaverse group before and after the intervention (P=.006). CONCLUSIONS This study is the first to show that delivering exercise videos through metaverse space can increase physical activity in young adults by providing a gathering space for individuals similarly motivated for exercise practice. This way, the sense of isolation during exercise is reduced compared with merely distributing videos on YouTube. The use of metaverse space in health promotion is likely to spread, and this study provides a useful reference for its exploration.

Abstract
Due to the definitive known effect of magnesium on insulin resistance and the fact that insulin resistance is a main etiology in polycystic ovary syndrome (PCOS), it is assumed the use of magnesium supplements can improve insulin resistance, lipid profiles, and glucose and thus may also play a role in improving the clinical condition of patients with PCOS. We aimed to assess the effects of magnesium supplements on anthropometric, clinical, and metabolic parameters in women suffering from PCOS. This triple-blind randomized clinical trial study was conducted on women aged 15-35 years with PCOS. The patients were randomly assigned to receive a magnesium oxide supplement (250 mg/day for 2 months) or a placebo. The study parameters were evaluated and compared between two groups before as well as 2 months and 5 months after the initial assessment. In total, 40 cases (20 in each group) were recruited in the study. A significant reduction in the serum insulin level (P-value = 0.036) and insulin resistance (p-value = 0.032) was observed in the case group. Prescribing magnesium supplements could also lead to lowering total cholesterol, low-density lipoprotein, and fasting blood sugar along with increasing the level of high-density lipoprotein. We could not find any significant difference in anthropometric parameters as well as the mean systolic and diastolic blood pressures before and after intervention between the two groups. Although the rate of oligomenorrhea significantly decreased in the two study groups, it was no different across the two groups before and also after the intervention. The use of magnesium supplements in patients with PCO, regardless of the etiology or progression of the disease, can greatly improve the metabolic status of these patients by improving insulin resistance and modulating the level of lipid profile.

Plain language summary
Irritable bowel syndrome (IBS) is a common disorder of gut-brain interaction in which recurrent abdominal pain is associated with defecation or a change in bowel habits. Various therapeutic options for IBS target the underlying pathophysiological aspects of the condition. Unfortunately, no single approach can effectively address this disorder’s diverse manifestations simultaneously. The aim of this study was to identify markers for recognising non-constipated (NC) IBS patients that may show significant clinical improvements upon treatment with the probiotic strain Lacticaseibacillus paracasei DG (LDG). This study is based on a multicentre, randomised, double-blind, parallel-group, placebo-controlled clinical trial. A total of 63 patients were included in this study who were randomised to receive a probiotic treatment or placebo capsules for 12 weeks. Results showed that the probiotic bacterium LDG can be clinically effective in a subgroup of non-constipated IBS patients characterised by an altered faecal microbiota which resembles that observed in metabolic syndrome-associated pathologic or pre-pathologic conditions. Furthermore, a bacterium reported to contribute to pro-inflammatory immune states, was positively associated with markers of increased endothelial permeability and liver functionality Authors concluded that an analysis of the faecal microbiota focused on particular bacteria could permit the identification of NC-IBS patients who can obtain a significant clinical benefit from the probiotic treatment.
Abstract
Probiotics are exploited for adjuvant treatment in IBS, but reliable guidance for selecting the appropriate probiotic to adopt for different forms of IBS is lacking. We aimed to identify markers for recognizing non-constipated (NC) IBS patients that may show significant clinical improvements upon treatment with the probiotic strain Lacticaseibacillus paracasei DG (LDG). To this purpose, we performed a post-hoc analysis of samples collected during a multicenter, double-blind, parallel-group, placebo-controlled trial in which NC-IBS patients were randomized to receive at least 24 billion CFU LDG or placebo capsules b.i.d. for 12 weeks. The primary clinical endpoint was the composite response based on improved abdominal pain and fecal type. The fecal microbiome and serum markers of intestinal (PV1 and zonulin), liver, and kidney functions were investigated. We found that responders (R) in the probiotic arm (25%) differed from non-responders (NR) based on the abundance of 18 bacterial taxa, including the families Coriobacteriaceae, Dorea spp. and Collinsella aerofaciens, which were overrepresented in R patients. These taxa also distinguished R (but not NR) patients from healthy controls. Probiotic intervention significantly reduced the abundance of these bacteria in R, but not in NR. Analogous results emerged for C. aerofaciens from the analysis of data from a previous trial on IBS with the same probiotic. Finally, C. aerofaciens was positively correlated with the plasmalemmal vesicle associated protein-1 (PV-1) and the markers of liver function. In conclusion, LDG is effective on NC-IBS patients with NC-IBS with a greater abundance of potential pathobionts. Among these, C. aerofaciens has emerged as a potential predictor of probiotic efficacy.

Abstract
OBJECTIVE To test the efficacy of cognitive-behavioural therapy (CBT) for lifestyle modification in patients with metabolic syndrome (MetS). DESIGN 76 MetS patients completed this clinical trial, with 18 months follow-up. 45 participants from the experimental group (EG - CBT) and 31 to the control group (CG - usual care). The CBT programme was performed by a psychologist in a face-to-face group format, during 12 weekly sessions lasting 90 minutes. The intervention for the CG consisted of workshops with basic information about MetS and it's associated cardiovascular risk. MAIN OUTCOME MEASURES Efficacy of (CBT) in (MetS) patients. RESULTS Results showed reduction in weight (mean difference - MD -2.633, 95%CI [-4.322, -0.943]; p<.003), waist circumference (MD -2.944, 95%CI [-5.090, -0.798]; p<.008), body mass index (MD -0.915, 95%CI [-1.494, -0.335]; p<.003), systolic (MD -0.046, 95%CI [-0.685, -0.023]; p<.0002) diastolic blood pressure (MD -4.777, 95%CI [-7.750, -1.804]; p<.002), and cardiovascular risk score after 18 months. An increase in adherence to the Mediterranean diet and assertiveness and a reduction in anger were observed in EG. The CG did not show any significant differences. CONCLUSION The CBT focused on changes in lifestyle seems to be effective in the reduction of MetS and cardiovascular risk factors.

Abstract
BACKGROUND Prevalence of metabolic syndrome (MetS) increased from one-quarter to one-third of the U.S. adult population over 8 years and is spreading to young adults and Asian and Hispanic Americans. Diagnosed when >3 out of 5 cardiometabolic risk factors are present, there is widespread agreement that its fundamental roots are in a lifestyle characterized by poor dietary quality and physical inactivity. Past lifestyle trials for MetS produce benefits that have limited sustainability, suggesting the need for new treatment approaches. METHODS This is the design and baseline cohort of the Enhancing Lifestyles in the Metabolic Syndrome (ELM) multi-site trial. The trial tests the hypothesis that a habit-based lifestyle treatment offered over 6 months, followed by 18 monthly maintenance contacts, can produce 4 new diet, physical activity, and mindfulness habits and, if so, sustained MetS remission. The design is an individually randomized, partially clustered group treatment trial of 618 participants with the MetS recruited from 5 sites in the U.S. and randomized to a small group lifestyle treatment or an enhanced standard of care education comparator. The primary outcome is MetS remission at 24 months. Secondary outcomes compare arms at 6, 15, and 24 months on MetS components, lifestyle targets, weight, body mass index, hemoglobin A1c, LDL cholesterol, medications, quality of life, psychosocial factors, and cost-effectiveness. RESULTS The cohort of 618 participants was recruited by screening 14,817 over 2.5 years (screening to enrollment ratio 24:1). Recruitment exceeded the target of 600 despite 2 COVID-19 pauses. The mean age was 55.5 years, 24.3% were male, 25.5% were a racial minority, 9.7% identified as Hispanic, and 83.0% were classified as obese (body mass index >30). The most common MetS components were abdominal obesity (97.7%) and elevated blood pressure or antihypertensive medication (86.2%). CONCLUSIONS The geographic, sociodemographic, and clinical diversity of the cohort, combined with rigorous behavioral efficacy trial methods, will provide a conclusive answer to the question of whether this habit-based lifestyle program can produce sustained 24-month remission of the MetS and thereby help to curb a significant and growing public health problem.

Abstract
PURPOSE This study aimed to explore the effects of 20 weeks of multicomponent or power training with elastic bands (EBs) on metabolic and inflammatory blood parameters, body composition, anthropometry, and physical function in older women with metabolic syndrome (MS). METHODS Ninety participants were randomly assigned to a multicomponent (MCG; n = 30), power (PG; n = 30), or a control group (CG; n = 30). The MCG performed balance, slow-speed strength, and aerobic training, twice per week. The PG completed a high-speed resistance training program twice per week, composed of three to four sets of ten repetitions of six overall body exercises at a perceived rating of effort for the first repetition of 3-4 on the OMNI-Resistance Exercise Scale EB. MS-related variables (glucose, triglycerides, and waist circumference) and cardiometabolic risk factors (high-density lipoprotein [HDL], glycosylated hemoglobin, total cholesterol, low-density lipoprotein cholesterol [LDL], C-reactive protein, and anthropometric profile) were assessed. Physical function was evaluated through balance, strength, and mobility tests. RESULTS An analysis of variance revealed that both training groups similarly improved most glycemic and lipidic profile parameters (p ≤ 0.006; d ≥ 0.46), body composition and anthropometry (p < 0.001; d ≥ 0.41), and physical function (p ≤ 0.005; d ≥ 0.69). Opposed to the PG, the MCG improved balance (p < 0.001; d = 0.96) and decreased the inflammatory status by downregulating C-reactive protein (p = 0.003; d = 0.47). On the other hand, the PG exhibited improvements in handgrip strength (p = 0.006; d = 0.48), while the MCG did not. CONCLUSION Therefore, multicomponent and power training with EBs are plausible strategies for improving the cardiometabolic health status and physical function in older women with MS.

Abstract
BACKGROUND Erectile dysfunction (ED) and metabolic syndrome (MeTS) are highly prevalent in chronic plaque psoriasis (CPP). OBJECTIVE The aim of this lifestyle modification study is to explore the response of MeTS components and ED to a 12-week lifestyle modification program (low-calorie diet and moderate-intensity treadmill walking) in 60 obese men with CPP, mild and moderate ED, and MeTS. THE DESIGN, SETTINGS, PARTICIPANTS, AND INTERVENTION In this lifestyle modification randomized study, a university-based hospital recruitment of 60 obese men with CPP, mild and moderate ED, and MeTS was randomly performed. Men were randomly assigned to the lifestyle modification group (n = 30, received low-calorie diet and moderate-intensity treadmill walking programs) or waitlist group (n = 30). The following outcomes were assessed as follows: body mass index, psoriasis severity (assessed via psoriasis area and severity index), ED (assessed by the five-item internal index of erectile function), and components of MeTS (waist circumference, blood pressure, serum high-density lipoprotein, serum triglycerides, and serum fasting blood glucose). RESULTS Trends of significant improvements in all outcomes were documented in favor of the lifestyle modification group. All outcomes of the waitlist group did not show the same reported significant improvements of the lifestyle modification group. CONCLUSION A 12-week lifestyle modification program as a tool for weight loss in obese men with CPP is a good therapeutic method to improve psoriasis severity and psoriasis-associated ED and MeTS.

Abstract
Dyslipidemia is a component of metabolic syndrome, having an important role in the carcinogenesis of different tumor types, such as prostate, ovarian, or renal cancer. The number of studies on the predictive potential of the different components of the lipid profile with a predictive potential in breast cancer is quite low. The evaluation of the lipid profile was carried out for the 142 patients who benefited from neoadjuvant therapy (NAC) in order to identify a potential predictive biomarker. The serological sample collection was performed sequentially according to a standardized protocol, pre-NAC, post-NAC and 6 months post-NAC after a 6-h pre-collection fast. We also investigated in the general group the presence or absence of the p53 mutation (TP53) and of the mitotic index ki-67, respectively, in relation to the molecular subtypes. The menopausal status, tumor size, family history, grading, Ki-67, p53 and LN metastases have a predictive nature regarding overall survival (OS) (p < 0.05), while for disease free survival (DFS), only tumor size, tumor grading, Ki-67 > 14, and p53+ are of predictive nature. The genetic and molecular analysis carried out in our group indicates that 71.67% have a Ki-67 score higher than 14%, and 39% of the patients have the positive P53 mutation. The multivariate analysis in the case of patients included in the TNBC subtype showed that the increased tumor volume (p = 0.002) and increased level of HDL (p = 0.004) represent predictive factors for the tumor response rate to NAC. High HDL-C levels before NAC and increased LDL-C levels after NAC were associated with the better treatment response in ER-positive and HER2+ breast cancer patients. Increased HDL-C values and tumor volume represent predictive factors as to the response rate to NAC in the case of patients included in the TNBC subtype. Regarding the ER+ and HER2+ subtypes, increased levels of HDL-C pre-NAC and increased levels of LDL-C post-NAC were associated with a better therapeutic response rate. Tumor grading, Ki-67, p53, and LN metastases have a predictive nature for OS, while tumor size, tumor grading, and Ki-67 > 14, and p53+ are predictive for DFS.

Abstract
BACKGROUND AND AIM Metabolic syndrome is associated with health conditions and neurological disorders. Brain-derived neurotrophic factor (BDNF) plays a protective role on the nervous system. Decreased levels of BDNF have been shown in MetS and neurodegenerative diseases. There is promising evidence regarding the anti-inflammatory antioxidant, and neuroprotective properties of virgin coconut oil (VCO). The aim of this study was to evaluate the effects of VCO consumption on serum BDNF levels, oxidative stress status, and insulin resistance in adults with MetS. METHODS This randomized controlled clinical trial was conducted on 48 adults with MetS aged 20-50 years. The intervention group received 30 ml of VCO daily to substitute the same amounts of oil in their usual diet. The control group continued their usual diet. Serum BDNF levels, total antioxidant capacity (TAC), malondialdehyde (MDA) as well as HOMA-IR and QUICKI index were measured after four weeks of intervention. RESULTS VCO consumption significantly reduced serum levels of MDA (p = .01), fasting insulin (p < .01) and HOMA-IR index (p < .01) and increased serum TAC (p < .01) and QUICKI index (p = .01) compared to the control group. Serum BDNF levels increased significantly in VCO group compared to the baseline (p = .02); however, this change was not significant when compared to the control group (p = .07). CONCLUSION VCO consumption improved oxidative stress status and insulin resistance and had a promising effect on BDNF levels in adults with MetS. Further studies are needed to understand the long-term effects of VCO consumption.
