Abstract Background Atherosclerotic cardiovascular disease (ASCVD) develops over a prolonged latent period, progressing from subclinical ASCVD to major cardiovascular events due to plaque accumulation. Subclinical ASCVD is a valid subrogate to assess potential risk factors or ASCVD. Dietary patterns are known to contribute to or prevent ASCVD. Dairy consumption has been associated with lower rates of obesity, hypertension, and diabetes, while saturated fats, present in most dairy products, have been associated with ASCVD. Studies assessing the association between subclinical ASCVD and dairy consumption have shown mixed results but have not been systematically analyzed Purpose This study aimed to systematically review and synthesize the existing evidence on the association between dairy product consumption and subclinical ASCVD Methods The study protocol was registered in the International Prospective Register of Systematic Reviews and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. We conducted a comprehensive search of PubMed, EMBASE, Scopus, Cochrane Central Register, Google Scholar, and Web of Science to identify experimental and observational studies that examined the association of dairy product consumption with measures of subclinical ASCVD assessed through coronary artery calcium (CAC) scanning, intima-media thickness (IMT), pulse pressure (PP) or pulse wave velocity (PWV), from inception to July 9, 2024. Titles and abstracts were screened in duplicate, followed by a full-text review and data abstraction from articles that met the study criteria. Dairy products were classified as: a) Dairy, according to the United States Department of Agriculture, encompassing milk, yogurt, cheese, lactose-free milk, and fortified soy milk/yogurt; and b) Dairy+, which further included higher fat content products such as cream cheese, sour cream, cream, and butter Results A total of 973 articles were identified; 22 met inclusion criteria representing 20 studies; being predominantly cross-sectional (55%) conducted in North America (50%); food frequency questionnaires were the most implemented tool for dietary assessment (86%), and 41% used PWV for subclinical ASCVD assessment; Fig. 1. Total Dairy and Dairy+ exhibited predominantly neutral effects with a trend toward a beneficial effect, similar to yogurt intake. Milk and cheese demonstrated contrasting effects, with studies reporting protective, neutral, and harmful associations, particularly for PWV and IMT. Limited data on CAC suggested no strong relationship with dairy consumption; Table 1 Conclusion Available evidence on the association between dairy consumption and subclinical ASCVD is complex with mixed effects across dairy products. No consistent evidence of harm or benefit was found; future research is needed to clarify the role of different dairy components in the development of subclinical ASCVD and incidence of cardiovascular eventsFig1.Summary of studies characteristics Table 1.Summary of effects

SummaryMetabolic and Bariatric Surgery (MBS) is effective in improving metabolic outcomes and reducing weight in patients with obesity and diabetes, with less explored benefits in type 1 diabetes (T1D). This study aimed to evaluate the impact of MBS on weight loss and insulin requirements in T1D patients compared to insulin‐treated type 2 diabetes (T2D) patients over a 5‐year period. This retrospective analysis included patients who underwent primary sleeve gastrectomy (SG) or Roux‐en‐Y gastric bypass (RYGB) with a confirmed preoperative diagnosis of either T1D or insulin‐treated T2D. Primary endpoints focusing on weight loss and secondary outcomes assessing changes in insulin dosage and glycemic control. After 5 years, weight loss was similar across groups, with total weight loss at 14.2% for T1D and 17.6% for insulin‐treated T2D in SG, and 22.6% for T1D vs. 26.8% for insulin‐treated T2D in RYGB. Additionally, there was a significant reduction in median daily insulin doses from 140.5 units at baseline to 77.5 units at 1 year postoperatively, sustained at 90 units at 5 years. The differential impact of MBS procedure was also highlighted, where RYGB patients showed a more pronounced and enduring decrease in insulin requirements compared to SG.

Background Obesity is increasingly common in kidney transplant candidates and may limit access to transplantation. Obesity and diabetes are associated with a high risk for post-transplant complications. The best approach to weight loss to facilitate active transplant listing is unknown, but bariatric surgery is rarely considered due to patient- and physician-related apprehension, among other factors. Methods We aimed to determine the magnitude of weight loss, listing, and transplant rates in 28 candidates with a mean BMI of 44.4±4.6 kg/m 2 and diabetes treated conservatively for 1 year post weight-loss consultations (group 1). Additionally, we evaluated 15 patients (group 2) who met the inclusion criteria but received bariatric intervention within the same time frame. All patients completed a multidisciplinary weight management consultation with at least 1 year of follow-up. Results In the conservatively managed group (group 1), the mean weight at the time of initial consultation was 126.5±18.5 kg, and the mean BMI was 44.4±4.6 kg/m 2 . At 1 year post weight-loss consultation, the mean weight decreased by 4.4±8.2 kg to 122.9±17 kg, and the mean BMI was 43±4.8 kg/m 2 , with a total mean body weight decrease of 3% ( P =0.01). Eighteen patients (64%) did not progress to become candidates for active listing/transplantation during the follow-up time of 4±2.9 years, with 15 (54%) subsequently developing renal failure/diabetes-related comorbidities prohibitive for transplantation. In contrast, mean total body weight decreased by 19% at 6 months post bariatric surgery, and the mean BMI was 34.2±4 and 32.5±3.7 kg/m 2 at 6 and 12 months, respectively. Bariatric surgery was strongly associated with subsequent kidney transplantation (HR=8.39 [95% CI 1.71 to 41.19]; P =0.009). Conclusions A conservative weight-loss approach involving multidisciplinary consultation was ineffective in most kidney transplant candidates with diabetes, suggesting that a more proactive approach is needed.

Introduction Severe obesity is a growing epidemic that causes significant morbidity and mortality, and is particularly difficult to reverse. Efficacious and cost-effective interventions are needed to combat this epidemic. This study hypothesized that obese people (body mass index (BMI) ≥35 kg/m 2 ) using a remote weight-loss program combining a mobile application, wireless scales, and low-calorie meal replacement would experience clinically significant weight loss. Methods This study was a retrospective observational analysis of 8275 individuals with a baseline BMI ≥35 kg/m 2 who used a remote weight-loss program combining mobile applications, frequent self-weighing, and calorie restriction via meal replacement for a minimum of 35 days. Weight changes were evaluated at multiple intervals (42, 60, 90, and 120 days), and weight loss was evaluated for all and for pre-specified subgroups based on demographic features and frequency of self-weighing. Results Mean weight loss at 42 days ( N = 6781) was 8.1 kg (margin of error (MOE) = 0.126 kg) with 73.6% of users experiencing >5% total body weight loss. Both men (9.1 kg; MOE = 0.172 kg; 7.9% from baseline) and women (7.1 kg; MOE = 0.179 kg; 7.2% from baseline) experienced significant weight loss. At the 120-day interval ( N = 2914), mean weight loss was 14 kg (MOE = 0.340 kg), 13% total body weight loss from baseline, and 82.3% of participants had lost >5% of their initial body weight. The decrease in body-fat percent correlated well with weight loss ( R = 0.92; p < 0.001). Conclusions In a large cohort of individuals with class II or III obesity, a remote weight-loss program combining mobile applications, daily self-weighing, and calorie restriction via meal replacement resulted in dramatic weight loss among subjects who were active users when evaluated through a retrospective observational analysis.

Introduction: Metabolic Syndrome represents a constellation of findings known to increase cardiovascular risk and all-cause mortality and is becoming more frequent in China. Smartphone applications may provide a cost-effective method to engage in weight loss and improve metabolic syndrome components. Methods: Prospective study of changes in weight and metabolic syndrome risk factors at 6 weeks and 6 months using a smartphone application utilizing a wireless scale, meal replacement biscuits and e-coaching in China. All participants had or were at high risk for metabolic syndrome and all interaction was online, without face to face contact. Results: 218 individuals ,55% female, participated. Median weight loss at 6 weeks and 6 months was 7.3kg and 8.4 kg (P<0.001) respectively. At baseline, 60% met a diagnosis of metabolic syndrome this dropped to 38% at 6 weeks (P<0.001) and stayed at 38% at 6 months (P<0.001). At 6 week the prevalence of all components of metabolic syndrome were improved (P<0.05) except HDL. Conclusions: A smartphone weight loss platform that utilizes a wireless scale, meal replacement biscuits and e-coaching was associated with significant weight loss and improvement in several metabolic syndrome components at 6 weeks and 6 months. This program may provide a scalable intervention against metabolic syndrome, especially in developing countries such as China.

INTRODUCTION: Obesity is associated with postnatal depression; however, the prevalence of postnatal depression in women after bariatric surgery has not been further evaluated. METHODS: For this observational investigation, women, ages 18-45 years, with pregnancy from 1989-2015 and bariatric surgery were identified using the Olmsted County Rochester Epidemiology Project and ICD-9 codes. Those with surgery after pregnancy and/or without permission to use their records were excluded. Charts were reviewed for maternal and infant characteristics and outcomes. Postnatal depression was identified from a positive screen, referral for mood disorder, antidepressant medication increase, suicidality, or provider diagnosis from delivery to 12 months postpartum. RESULTS: Ninety-one women with pregnancy >23 weeks after surgery and available data were reviewed. The average body mass index at time of surgery was 47±8.6 kg/m2 (N=88) and at time of pregnancy 32±6.6 kg/m2 (N=89). The average age at surgery was 29±4.1 years and at delivery 33±4.4 years. Roux-en-Y gastric bypass was the most common surgery (N=70, 77%). Pregnancy outcomes included: 14% preterm deliveries (<37 weeks, N=13), 67% vaginal deliveries (N=61), no stillbirths, and 97% singleton deliveries (N=88). Mean singleton birthweight was 3225 grams (±471, N=86). Postnatal depression was noted in 38% of women (N=35), which is significantly higher than that for obese women in general (13-18%) when a 1-sample proportion test is conducted for comparison (38%vs18%, p <0.0001). CONCLUSION: Postnatal depression may be increased in women with a history of bariatric surgery. Further investigation is needed, but particular care should be taken to screen and diagnose these high-risk women.

AimObesity is a major cardiovascular (CV) risk factor. Bariatric surgery (BSx) is an approved therapeutic alternative for class II–III obesity, but little evidence focuses on older adults. We assessed the effect of BSx on cardiometabolic variables and long‐term CV risk in older adults.MethodsWe carried out a population‐based, observational study from 1990–2009, of 40 consecutive elderly (age ≥60 years) residents of Olmsted County, MN, USA, with class II–III obesity treated with BSx at a University‐based, academic health center. Data were obtained from the Rochester Epidemiology Project. Metabolic syndrome (MetS) was defined using American Heart Association/National Heart, Lung, Blood Institute (AHA/NHLBI) criteria (increased triglycerides, low high‐density lipoprotein, increased blood pressure, increased glucose and body mass index as a modified measure of obesity instead of waist circumference). Change in CV risk factors, MetS prevalence, and impact on predicted CV risk using the Framingham risk score was ascertained at 1 year postoperatively and assessed statistically.ResultsMean age and body mass index were 64.4 ± 3.7 and 45.0 ± 6.3 kg/m2, respectively, and 28 out of 40 (70%) were women. One participant died during the 11‐month study period after BSx from respiratory complications related to BSx, and one participant died at 2 years. Percentage of excess weight loss decreased by 57.5% at 1 year. Prevalence 1 year after BSx decreased for diabetes (57.5% to 22.5%; P < 0.03), hypertension 87.5% to 73.7% (P = 0.003), dyslipidemia (80% to 42.5%; P < 0.001) and sleep apnea (62.5% to 23.7%; P < 0.001).MetS prevalence decreased from 80% to 45% (P < 0.002). Baseline risk was 14.1%, which changed at follow up at 8.2%.ConclusionsIn older adults, BSx induces considerable weight loss, improves CV risk factors, decreases MetS prevalence and is an effective treatment in this population.
