RÉSUMÉ

With changes in lifestyle behaviors, including dietary structure and habits, the prevalence of Youth-onset Type 2 Diabetes Mellitus (YODM) has increased 2 to 3 times compared to 30 years ago. YODM patients experience complications earlier, progress faster, and exhibit more severe symptoms. However, limited and inconclusive direct evidence, coupled with poor patient compliance, poses challenges in the clinical management of YODM. Apart from the continuous decline in pancreatic ß-cell function and quantity, tissue-specific insulin resistance (IR) is also a typical characteristic of YODM. The main mechanisms of IR in YODM involve different aspects such as obesity, dietary imbalance, abnormal substance metabolism, chronic inflammation, oxidative stress, and hormonal fluctuations during adolescence. For the comprehensive management of YODM, besides achieving good control of blood glucose levels, it may be necessary to apply the most appropriate methods considering the uniqueness of the patient population and the specifics of the disease. Early identification and detection of the disease are crucial. Precise screening of patients with well-functioning pancreatic insulin ß-cells, primarily characterized by IR and obesity, represents the population most likely to achieve diabetes remission or reversal through lifestyle modifications, medications, or even surgical interventions. Additionally, considering potential emotional disorders or the impact of adolescent hormones in these patients, health education for patients and caregivers is essential to make them aware of the long-term benefits of well-controlled blood glucose. In conclusion, adopting comprehensive management measures to achieve diabetes remission or reversal is the ideal goal. Controlling high blood glucose, obesity, and other risk factors related to diabetes complications is the next priority to delay the occurrence and progression of complications. A comprehensive perspective on IR provides insights and references for identifying YODM and its management strategies.

RÉSUMÉ

OBJECTIVE: We aimed to investigate the impact of sarcopenia and sarcopenic obesity (SO) on the clinical outcome in older patients with COVID-19 infection and chronic disease. METHODS: We prospectively collected data from patients admitted to Huadong Hospital for COVID-19 infection between November 1, 2022, and January 31, 2023. These patients were included from a previously established comprehensive geriatric assessment (CGA) cohort. We collected information on their pre-admission condition regarding sarcopenia, SO, and malnutrition, as well as their medical treatment. The primary endpoint was the incidence of intubation, while secondary endpoints included in-hospital mortality rates. We then utilized Kaplan-Meier (K-M) survival curves and the log-rank tests to compare the clinical outcomes related to intubation or death, assessing the impact of sarcopenia and SO on patient clinical outcomes. RESULTS: A total of 113 patients (age 89.6 ± 7.0 years) were included in the study. Among them, 51 patients had sarcopenia and 39 had SO prior to hospitalization. Intubation was required for 6 patients without sarcopenia (9.7%) and for 18 sarcopenia patients (35.3%), with 16 of these being SO patients (41%). Mortality occurred in 2 patients without sarcopenia (3.3%) and in 13 sarcopenia patients (25.5%), of which 11 were SO patients (28%). Upon further analysis, patients with SO exhibited significantly elevated risks for both intubation (Hazard Ratio [HR] 7.43, 95% Confidence Interval [CI] 1.26-43.90, P < 0.001) and mortality (HR 6.54, 95% CI 1.09-39.38, P < 0.001) after adjusting for confounding factors. CONCLUSIONS: The prevalence of sarcopenia or SO was high among senior inpatients, and both conditions were found to have a significant negative impact on the clinical outcomes of COVID-19 infection. Therefore, it is essential to regularly assess and intervene in these conditions at the earliest stage possible.

RÉSUMÉ

BACKGROUND: Dietary intervention is an important method to manage sarcopenic obesity, but the implementation in real world is difficult to achieve an ideal condition. This study aimed to the experiences of older people with sarcopenic obesity during the implementation of dietary behavioural change (DBC) intervention. METHODS: This study is a semi-structured individual interview embedded within a pilot randomized controlled trial on community-dwelling older people with sarcopenic obesity. Purposive sampling was applied to invite 21 participants who had received a 15-week DBC intervention. The interviews were audio-recorded and transcribed verbatim. Content analysis was performed to analyze the data. RESULTS: The themes for facilitators included: (a) Attach importance to self's health; (b) Family's support; (c) Concern self's body shape; (d) Instructor's support; (e) Regular food diary taken. The themes for barriers included: (a) Difficulties of taking food diary; (b) Difficulties of calculating the food amount; (c) Yield to offspring's appetite; (d) Misjudging self's or family's appetite. CONCLUSION: Support from family members and instructor, caring about self's health and body image facilitated the intervention implementation. The complication of food amount estimation and diary record, personal sacrifice for next generations, and previous living experience were barriers for implementing the intervention. Overall, the older people with sarcopenic obesity can accept the design of DBC intervention program and have great willing to join.

RÉSUMÉ

BACKGROUND AND AIMS: This study assessed whether the addition of continuous positive airway pressure (CPAP) during weight loss would enhance cardiometabolic health improvements in patients with obesity and Obstructive Sleep Apnoea (OSA). METHODS AND RESULTS: Patients with overweight or obesity, pre-diabetes and moderatesevere OSA were randomised to receive CPAP therapy with a weight loss programme (CPAP+WL) or a weight loss programme alone (WL alone). PRIMARY OUTCOME: 2-hour glucose assessed by an oral glucose tolerance test. SECONDARY OUTCOMES: 24 hr blood pressure, body composition (DEXA) and fasting blood markers. 17 patients completed 3-month follow-up assessments (8 CPAP+WL and 9 WL alone). Overall, participants in both groups lost ∼12 kg which reduced polysomnography determined OSA severity by ∼45 %. In the CPAP+WL group, CPAP use (compliance 5.29 hrs/night) did not improve any outcome above WL alone. There was no improvement in 2-hour glucose in either group. However, in the pooled (n = 17) analysis there were overall improvements in most outcomes including insulin sensitivity (.000965 units, p = .008), sleep systolic BP (- 16.2 mmHg, p = .0003), sleep diastolic BP (-9.8 mmHg, p = 0.02), wake diastolic BP (- 4.3 mmHg, p = .03) and sleepiness (Epworth Sleepiness Score -3.2, p = .0003). In addition, there were reductions in glucose area under the curve (-230 units, p = .009), total (-0.86 mmol/L, p = 0.006) and LDL cholesterol (-0.58 mmol/L, p = 0.007), triglycerides (-0.75 mmol/L, p = 0.004), fat mass (-7.6 kg, p < .0001) and abdominal fat (-310 cm3, p < .0001). CONCLUSION: Weight loss reduced OSA and improved sleepiness and cardiometabolic health. These improvements were not further enhanced by using CPAP. Results suggest weight loss should be the primary focus of treatment for patients with OSA and obesity.

RÉSUMÉ

ABSTRACT: African American (AA) women have the highest prevalence of obesity in addition to health disparities in preventable diet-related diseases (i.e., diabetes, hypertension), which places them at increased risk for cardiovascular disease. The purpose of this pilot study was to assess the feasibility, acceptability, and preliminary effectiveness of the Keto Prescribed+ (KetoRx+) program on associated physical and psychosocial outcomes among this population. The KetoRx+ program is a healthy eating and thinking educational intervention. The program combined online and in-person community group sessions over 8 weeks. The Keto Prescribed+ was found to be feasible and acceptable with comments on ways to increase acceptability from participants completing program (n = 10). Physical outcomes changed showed an average decrease in weight of 10lbs (SD = 5), baseline average 226lbs. Waist-to-hip ratio and systolic blood pressure also trended down. Psychosocial outcomes showed improvement trends. The KetoRx+ program is feasible and acceptable for overweight or obese AA women. Preliminary efficacy was established for most physical and psychosocial outcomes. However, more research is needed to identify specific program components contributing to healthy lifestyle behavior change and to establish program efficacy and effectiveness. Culturally adapted community-based biopsychosocial interventions using ketogenic nutrition therapy may help improve cardiovascular health of adult AA women.

RÉSUMÉ

INTRODUCTION: This contribution highlights novel developments and innovations in psychological psychotherapy for patients with obesity. It underscores the importance of an interdisciplinary approach to treatment, which incorporates not only traditional methods but also contemporary psychotherapeutic modalities such as Acceptance and Commitment Therapy (ACT). Current research suggests that assessing the effectiveness of psychotherapy should not solely rely on changes in weight, but should also consider other outcomes such as subjective quality of life and mental health. Furthermore, the role of telemedicine and blended psychotherapy is emphasized as promising approaches to enhance accessibility and effectiveness of treatment. Through a case study of a 55-year-old woman with obesity and psychiatric comorbidities, the effectiveness of a multimodal psychotherapeutic approach is demonstrated.

RÉSUMÉ

BACKGROUND: With the increasing incidence of obesity and the childbearing-age delay among women, a debate over obesity's impacts on pregnancy and neonatal outcomes becomes hot. The potential negative effects of obesity and aging on fertility lead to an idea, whether an obese female pursuing IVF treatment can benefit from an ideal BMI achieved over a long-time weight loss process at the cost of aging? We aimed to assess the association between body mass index (BMI) and clinical or neonatal outcomes in patients undergoing in vitro fertilization (IVF) treatment, for answering whether it is necessary to lose weight first for obese patients, particularly those at advanced age. METHODS: A retrospective cohort study was performed using multicentered data from China. The women were stratified into 5 groups in terms of pre-gravid BMI (kg/m2) with the WHO obesity standard (group 1: BMI < 18.5; group 2: 18.5 ≤ BMI < 23.0; group 3: 23.0 ≤ BMI < 25.0; group 4: 25.0 ≤ BMI < 30.0; group 5: BMI ≥ 30.0). The primary outcome was cumulative live birth rate (CLBR), and other clinical and neonatal outcomes were weighed as secondary outcomes. Multivariate logistic regression analyses were carried to evaluate the association between BMI and the CLBR, or between BMI and some neonatal outcomes. Furthermore, we implemented a machine-learning algorithm to predict the CLBR based on age and BMI. RESULTS: A total of 115,287 women who underwent first IVF cycles with autologous oocytes from January 2013 to December 2017 were included in our study. The difference in the CLBR among the five groups was statistically significant (P < 0.001). The multivariate logistic regression analysis showed that BMI had no significant impact on the CLBR, while women's age associated with the CLBR negatively. Further, the calculation of the CLBR in different age stratifications among the five groups revealed that the CLBR lowered with age increasing, quantitatively, it decreased by approximately 2% for each one-year increment after 35 years old, while little difference observed in the CLBR corresponding to the five groups at the same age stratification. The machine-learning algorithm derived model showed that BMI's effect on the CLBR in each age stratification was negligible, but age's impact on the CLBR was overwhelming. The multivariate logistic regression analysis showed that BMI did not affect preterm birth, low birth weight infant, small for gestational age (SGA) and large for gestational age (LGA), while BMI was an independent risk factor for fetal macrosomia, which was positively associated with BMI. CONCLUSIONS: Maternal pre-gravid BMI had no association with the CLBR and neonatal outcomes, except for fetal macrosomia. While the CLBR was lowered with age increasing. For the IVF-pursuing women with obesity plus advanced age, rather than losing weight first, the sooner the treatment starts, the better. A multicentered prospective study with a large size of samples is needed to confirm this conclusion in the future.

RÉSUMÉ

Oneirotherapy is a form of psychotherapy that is based on visual imagery and symbolism. In this communication. We discuss the role of oneirotherapy, or using vivid imagery, as adjuvant therapy in obesity care. Oneirotherapy can be used to promote acceptance of, and adherence to, prescribed therapy. It may also help improve quality of life and enhance self-esteem. However, oneirotherapy alone, without following a healthy lifestyle and or taking antiobesity medication, will help manage weight only in one's dreams.

RÉSUMÉ

BACKGROUND: Fecal microbiota transplantation (FMT) is a therapeutic intervention used to treat diseases associated with the gut microbiome. In the human gut microbiome, phages have been implicated in influencing human health, with successful engraftment of donor phages correlated with FMT treatment efficacy. The impact that gastrointestinal phages exert on human health has primarily been connected to their ability to modulate the bacterial communities in the gut. Nonetheless, how FMT affects recipients' phage populations, and in turn, how this influences the gut environment, is not yet fully understood. In this study, we investigated the effects of FMT on the phageome composition of participants within the Gut Bugs Trial (GBT), a double-blind, randomized, placebo-controlled trial that investigated the efficacy of FMT in treating obesity and comorbidities in adolescents. Stool samples collected from donors at the time of treatment and recipients at four time points (i.e., baseline and 6 weeks, 12 weeks, and 26 weeks post-intervention), underwent shotgun metagenomic sequencing. Phage sequences were identified and characterized in silico to examine evidence of phage engraftment and to assess the extent of FMT-induced alterations in the recipients' phageome composition. RESULTS: Donor phages engrafted stably in recipients following FMT, composing a significant proportion of their phageome for the entire course of the study (33.8 ± 1.2% in females and 33.9 ± 3.7% in males). Phage engraftment varied between donors and donor engraftment efficacy was positively correlated with their phageome alpha diversity. FMT caused a shift in recipients' phageome toward the donors' composition and increased phageome alpha diversity and variability over time. CONCLUSIONS: FMT significantly altered recipients' phage and, overall, microbial populations. The increase in microbial diversity and variability is consistent with a shift in microbial population dynamics. This proposes that phages play a critical role in modulating the gut environment and suggests novel approaches to understanding the efficacy of FMT in altering the recipient's microbiome. TRIAL REGISTRATION: The Gut Bugs Trial was registered with the Australian New Zealand Clinical Trials Registry (ACTR N12615001351505). Trial protocol: the trial protocol is available at https://bmjopen.bmj.com/content/9/4/e026174 . Video Abstract.

RÉSUMÉ

OBJECTIVES: To examine how gender-sensitive community weight-loss programmes have been used to address overweight and obesity in men and to identify what can be learnt from this rapidly evolving field. DESIGN: Scoping review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping review checklist for reporting. DATA SOURCES: A database search was conducted using EBSCOhost (Academic Search Complete, CINAHL Complete, Global Health, Health Source: Consumer Edition, Health Source: Nursing/Academic Edition and Medline Complete), Google, Google Scholar, Open Access Theses and Dissertations platform and Scopus. ELIGIBILITY CRITERIA: All weight-loss programmes using a gender-sensitive approach to address men's overweight and obesity in community settings. DATA EXTRACTION AND SYNTHESIS: Narrative synthesis was conducted based on the research questions and objectives. Primary outcomes include operationalisation, context and concept of the gender-sensitive approach. Information was reviewed and extracted to Microsoft Excel by two reviewers. RESULTS: A total of 40 studies (28 quantitative, eight mixed methods and four qualitative) were identified from 4617 records. Gender-sensitive approaches were undertaken in a range of settings and contexts including professional sports clubs (n=21), non-professional sporting clubs (n=16), workplace-based (n=2) and commercial organisation-based (n=1). The most common analysis approaches were evaluating the effect of the programmes (n=31) where positive impact was predominantly shown (eg, up to 3.9 kg weight reduction at 3-month follow-up). Programmes (ie, Football Fans in Training) were short-term cost-effective (eg, the cost was £862-£2228 per 5% weight reduction at 12-month follow-up). Qualitative evidence highlights factors that influenced men's participation (eg, camaraderie) and identifies areas for improvement. CONCLUSION: The findings demonstrate that gender-sensitive programmes for men's weight loss have been effectively applied using a range of different approaches and in a range of different contexts. Further evidence is needed to confirm the effectiveness of the programmes across diverse groups of men.

RÉSUMÉ

Evidence-based approaches for weight management in the United Kingdom are lacking. This study examined preferences for behavioural weight-management programmes amongst adults aged eighteen and over in Northern Ireland who had experience living with overweight (i.e., body mass index (BMI) ≥ 25 kg/m2). It involved the design and implementation of an online survey assessing previous experience with weight management and preferences for future weight-management programmes. A total of 94.7% of participants had previously engaged with weight-management services but many struggled to maintain weight loss. Older adults were more likely to be motivated to reduce their weight whilst younger adults were more likely be motivated to change their appearance. A focus on both wellbeing and weight-related outcomes was evident. Participants preferred programmes to be low-cost, delivered by a range of professionals by blended delivery, consisting of short (≤1 h) weekly sessions. These preferences highlighted important considerations for the components of future services to improve engagement and effectiveness.

RÉSUMÉ

Dietary and physical activity interventions through smartphone healthcare applications (apps) have recently surged in popularity as effective methods for weight loss. However, the specific factors contributing to successful weight loss remain uncertain. We conducted an analysis of baseline characteristics and app usage frequencies over three months among 68 Japanese adults with overweight and obesity who were assigned to the intervention group in a previous randomized controlled trial. Logistic regression analysis revealed a negative association (OR: 0.248; p = 0.018) between having a walking habit at baseline and successful weight loss, defined as a 3% reduction in initial weight. Additionally, slower walking speeds and family medical history were identified as potential predictors of successful weight loss. These findings offer insights into the profile of individuals who achieve success in weight loss through our smartphone app, providing valuable guidance for the development of future healthcare apps.

RÉSUMÉ

INTRODUCTION: Obesity is a chronic disease characterized by increased body fat mass and adipose tissue dysfunction, the pathogenesis of which is based on a neurobiological regulatory disorder of energy homeostasis. The primary aim of medical obesity therapy is to reduce the pathologically increased body fat mass and thus prevent secondary diseases and improve comorbidities. In this sense, bariatric-metabolic surgery is currently the most effective obesity therapy. In addition, new agents, which are essentially based on GLP-1 receptor agonism, are making pharmacological therapy increasingly effective. It is important to note that both bariatric-metabolic surgery as well as the pharmacological obesity therapy have direct effects on the central nervous regulation of energy homeostasis and, in particular, hunger and appetite, and therefore represent pathogenetically causal therapies. In this overview, we aim to shed light on the aforementioned medical interventions for obesity therapy and place them in the context of a pathogenetic disease concept.

RÉSUMÉ

INTRODUCTION: Individuals with obesity who undergo surgical or pharmacological therapies achieve good results in terms of weight and cardiometabolic risk reduction. It is not uncommon for those affected to equate the extent of weight loss achieved, with long-term treatment success. What is overlooked is that, in addition to obesity, significant weight loss also carries a risk of sarcopenia. Sarcopenic obesity and sarcopenia, in turn, increase the risk of cardiometabolic diseases. Physical activity has the potential to counteract cardiometabolic disease risk caused by obesity and sarcopenia. The underlying mechanism is contained in the endocrine organ skeletal muscle. The production and release of myokines in particular counteracts sarcopenic obesity and its complications. Physical activity is required to initiate myokine production. Endurance and strength training proves to be an effective training combination. In order to achieve a sustainable cardiometabolic risk reduction, the objectives and timing of physical activity should therefore be divided into two phases, a preparatory phase and an actual weight loss phase.

RÉSUMÉ

BACKGROUND: Digitally delivered weight loss programmes can provide a convenient, potentially cheaper, and scalable treatment option for people who may need to lose weight. However, outcomes are often inferior to in-person interventions in the long-term. This trial will use principles from the Multiphase Optimisation Strategy (MOST) framework to test whether it can enhance the effectiveness of a commercial digital behavioural weight loss programme. This trial aims to identify an optimised combination of four intervention components to enhance weight loss over a 24-week period. We will also explore which components contribute to improvements in participant retention and engagement with the programme. METHODS: Approximately 1400 adults with a BMI > 21 kg/m2 will be enrolled and randomised to one of 16 experimental conditions in a 24 factorial cluster design. The trial will test four intervention components: an introductory video call with the health coach, drop-in webchat sessions with the health coach, goal setting statements, and food diary review and feedback. All participants will receive the core digital behavioural weight loss programme and up to four new intervention components. Participation in the trial will last for 24 weeks. The primary outcome will be weight change at 16 weeks. Other outcomes, measured at 4, 16, and 24 weeks, include programme drop-out and engagement (number of interactions with the three main app functions). Fidelity and acceptability will be assessed using data on component adherence and self-report questionnaires. Decision-making for the enhanced programme will be based on components that contribute to at least a minimal improvement in weight loss, defined as ≥ 0.75kg, alone or in combination with other components. DISCUSSION: The factorial design is an efficient way to test the efficacy of behavioural components alone, or in combination, to improve the effectiveness of digital weight loss programmes. This trial will test the implementation of the MOST framework in an industry setting, using routinely collected data, which may provide a better way to refine and evaluate these types of interventions in a model of continuous service improvement.

RÉSUMÉ

Infertility among women, particularly those living with obesity, presents a multifaceted challenge with implications for reproductive health worldwide. Lifestyle interventions, mainly focusing on weight loss, have emerged as promising strategies to improve fertility outcomes in this population. This review aims to explore the effectiveness of various lifestyle interventions, encompassing dietary modifications and exercise regimens, in enhancing fertility outcomes among women with obesity and associated conditions such as polycystic ovary syndrome, congenital adrenal hyperplasia, type 2 diabetes mellitus, premenopause, hypothyroidism and eating disorders. Methodology of study search encompass a broad spectrum, ranging from interventions targeting weight management through slow or rapid weight loss to dietary approaches emphasizing whole food groups, specific nutrients, and dietary patterns like low-carbohydrate or ketogenic diets, as well as the Mediterranean diet. By synthesizing existing findings and recommendations, this review contributes to the understanding of lifestyle interventions in addressing infertility, with an emphasis on the population of women of reproductive age with excess weight and known or unknown infertility issues, while promoting their integration into clinical practice to optimize reproductive health and overall well-being.

RÉSUMÉ

INTRODUCTION: Behavioural weight loss programmes are generally accepted as being beneficial in reducing cardiometabolic risk and improving patient-reported outcomes. However, prospective data from large real-world cohorts are scarce concerning the mid-term and long-term impact of such interventions. The objective of this large prospective cohort study (n>10 000 participants) is to demonstrate the effectiveness of the standardised Nutritional and Psycho-Behavioural Rehabilitation programme (RNPC Programme) in reducing the percentage of subjects requiring insulin and/or other diabetes drug therapy, antihypertensive drugs, lipid-lowering therapies and continuous positive airway pressure therapy for obstructive sleep apnoea after the end of the intervention. The rate of remission of hypertension, type 2 diabetes and sleep apnoea will also be prospectively assessed. METHODS: This is a prospective multicentre observational study carried out in 92 RNPC centres in France. Participants will follow the standardised RNPC Programme. The prospective dataset will include clinical, anthropometric and biochemical data, comorbidities, medications, body composition, patient-reported outcome questionnaire responses, sleep study data with objective measurements of sleep apnoea severity and surrogate markers of cardiovascular risk (ie, blood pressure and arterial stiffness). About 10 000 overweight or obese participants will be included over 2 years with a follow-up duration of up to 5 years. ETHICS AND DISSEMINATION: Ethical approval for this study has been granted by the Ethics Committee (Comité de protection des personnes Sud-Est I) of Saint-Etienne University Hospital, France (SI number: 23.00174.000237). Results will be submitted for publication in peer-review journals, presented at conferences and inform the design of a future randomised controlled trial in the specific population identified as good responders to the RNPC Programme. TRIAL REGISTRATION NUMBER: NCT05857319.

RÉSUMÉ

In this multi-professional review, we will provide the in-depth knowledge required to work in the expanding field of obesity treatment. The prevalence of obesity has doubled in adults and quadrupled in children over the last three decades. The most common treatment offered has been lifestyle treatment, which has a modest or little long-term effect. Recently, several new treatment options-leading to improved weight loss-have become available. However, long-term care is not only about weight loss but also aims to improve health and wellbeing overall. In the era of personalized medicine, we have an obligation to tailor the treatment in close dialogue with our patients. The main focus of this review is new pharmacological treatments and modern metabolic surgery, with practical guidance on what to consider when selecting and guiding the patients and what to include in the follow-up care. Furthermore, we discuss common clinical challenges, such as patients with concurrent eating disorder or mental health problems, and treatment in the older adults. We also provide recommendations on how to deal with obesity in a non-stigmatizing way to diminish weight stigma during treatment. Finally, we present six microcases-obesity treatment for persons with neuropsychiatric disorders and/or intellectual disability; obesity treatment in the nonresponsive patient who has "tried everything"; and hypoglycemia, abdominal pain, and weight regain after metabolic surgery-to highlight common problems in weight-loss treatment and provide personalized treatment suggestions.

RÉSUMÉ

Obesity in the United States has risen to 42 percent of its adult population and is similarly problematic in many other countries. Although the U.S. government has provided education on healthy eating and the need to exercise regularly, behavioral obesity treatments have largely failed to sustain reductions in weight. Self-regulation, and the incorporation of exercise for its psychological impacts on eating, has sometimes been targeted. While there has been sporadic investigation into the carry-over of exercise-related self-regulation to eating-related self-regulation, the present aim is to further inquiry in that area to inform future treatment content for improved effects. Women enrolled in community-based obesity treatments with either a self-regulation (n = 106) or education (n = 54) focus were assessed on changes in exercise- and eating-related self-regulation, negative mood, completed exercise, and weight. Improvements were significantly greater in the self-regulation-focused group. After controlling for initial change in eating-related self-regulation, change in that measure from Month 3 to 6 was significantly predicted by change in exercise-related self-regulation during the initial 3 treatment months. This suggested a carry-over effect. A stronger predictive relationship was associated with the self-regulation-focused treatment. In further analyses, paths from changes in exercise→negative mood→self-regulation of both exercise and eating were significant. Increase in eating-related self-regulation was significantly associated with weight loss over 6, 12, and 24 months. The self-regulation-focused group had stronger relationships, again. Findings suggested utility in targeting exercise-related self-regulation to impact later change in eating-related self-regulation, and the use of exercise-associated mood improvement to bolster participants' self-regulation capabilities.

RÉSUMÉ

Metabolic syndrome encompasses amongst other conditions like obesity and type-2 diabetes and is associated with gut microbiome (GM) dysbiosis. Fecal microbiota transplantation (FMT) has been explored to treat metabolic syndrome by restoring the GM; however, concerns on accidentally transferring pathogenic microbes remain. As a safer alternative, fecal virome transplantation (FVT, sterile-filtrated feces) has the advantage over FMT in that mainly bacteriophages are transferred. FVT from lean male donors have shown promise in alleviating the metabolic effects of high-fat diet in a preclinical mouse study. However, FVT still carries the risk of eukaryotic viral infections. To address this, recently developed methods are applied for removing or inactivating eukaryotic viruses in the viral component of FVT. Modified FVTs are compared with unmodified FVT and saline in a diet-induced obesity model on male C57BL/6 N mice. Contrasted with obese control, mice administered a modified FVT (nearly depleted for eukaryotic viruses) exhibits enhanced blood glucose clearance but not weight loss. The unmodified FVT improves liver pathology and reduces the proportions of immune cells in the adipose tissue with a non-uniform response. GM analysis suggests that bacteriophage-mediated GM modulation influences outcomes. Optimizing these approaches could lead to the development of safe bacteriophage-based therapies targeting metabolic syndrome through GM restoration.
