Abstract Background Rapid technological advancements have rendered many prior reviews of technology-integrated physical activity (PA) interventions in K–12 schools obsolete. A comprehensive analysis examining both the effects of these interventions and the specific roles that technology plays has been notably lacking. This review aimed to systematically examine the effects of technology-infused PA interventions and identify the specific types, roles, and contextual applications of technology within K–12 schools. Methods This systematic review adhered to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. A thorough search across seven electronic databases (CINAHL, ERIC/EBSCOhost, PsycINFO, PubMed/MEDLINE, Scopus, SPORTDiscus, and Web of Science) included studies published up to May 20, 2024. Only randomized controlled trials (RCTs), cluster-RCTs, or rigorous quasi-experimental designs with matched/statistically controlled comparisons (N-RCTs) examining technology-infused PA interventions for school-aged children and adolescents were considered. Results Fifty-eight studies met inclusion criteria. Wearable devices (e.g., accelerometers) were the most used for PA measurement. Other technologies like web-based platforms, mobile applications, and exergaming served as educational tools, communication platforms, or core intervention components. Interventions occurred primarily in classrooms, followed by physical education spaces, and extended to home/online environments, school breaks (e.g., recess), and before-school time. Overall, interventions positively affected PA levels and related outcomes (e.g., PA enjoyment), though effectiveness varied by technology type, design, and context. Conclusions Technology holds substantial potential to enhance PA promotion in schools, but its effectiveness hinges on well-designed interventions that consider the specific types and applications of technology.

ABSTRACT The International Code of Marketing of Breastmilk Substitutes (‘the Code’) was established to protect babies and young children from inappropriate marketing of formula milk, bottles and teats and avoid undue commercial influence on caregiver infant feeding practices, including undermining breastfeeding and safe and appropriate formula feeding. UK law encompasses some but not all of the Code. To address persisting concerns about the marketing of infant formula (IF) and follow‐on formula (FoF), we assessed labelling compliance in the UK against relevant provisions in the Code, UK law and Department of Health and Social Care (DHSC) Guidance Notes which interpret UK law. Data were collected during July and August 2022 by taking pictures of labels from company websites, in shops and online. We developed three labelling checklists to systematically assess compliance and to compare compliance scores between the regulatory frameworks, formula types and brands. We assessed 57 labels (n = 32 IF and n = 25 FoF) and found low overall compliance: 50% complied with UK law, 32% with Guidance Notes and 40% with the Code. None of the labels complied with provisions prohibiting idealising text and photographs, nutrition and health claims (where relevant) and cross‐promotion between formula types. In conclusion, UK IF and FoF labels violate many of the provisions of all three regulatory frameworks. This is evidence of inappropriate marketing. The UK law should be better enforced and strengthened in line with the Code to protect breastfeeding, support safer, appropriate formula feeding and lessen commercial influence on infant feeding practices.
Abstract Background The pathogenesis of metabolic syndrome (MetS) is strongly linked to dysbiosis in the gut microbiota. However, studies investigating the association between the dietary index of gut microbiota (DI-GM) and MetS are limited. As such, the present study aimed to examine the association between DI-GM and the prevalence of MetS, as well as long-term mortality among individuals in the United States. Methods Data from 30,372 participants, obtained from the 2007 to 2018 cycle of the National Health and Nutrition Examination Survey, were analyzed. Associations between DI-GM scores and the prevalence of MetS and long-term mortality were examined using weighted logistic regression and Cox regression, respectively. Restricted cubic spline (RCS) and subgroup analyses were performed to further explore these relationships. Results An inverse association was observed between DI-GM and the prevalence of MetS, with each 1-unit increase in DI-GM corresponding to an 8.2% decrease in MetS prevalence (odds ratio 0.918 [95% CI 0.896–0.941]). Among participants with MetS, a 1-unit increase in DI-GM was associated with reduced risk for cardiovascular mortality (hazard ratio 0.922 [95% CI 0.854–0.994]). RCS analysis revealed a significant linear inverse association between DI-GM scores and MetS prevalence and cardiovascular mortality among participants with MetS. Subgroup analyses suggested that race, income level, and smoking status may modify the association between DI-GM and MetS prevalence. Conclusions Findings revealed that higher DI-GM scores were significantly associated with a lower prevalence of MetS in the general population and a reduced risk for cardiovascular mortality among individuals diagnosed with MetS. Further longitudinal studies are needed to confirm these associations and explore the underlying biological mechanisms.
Abstract
Objective:
To assess the nutritional quality of foods and beverages (F&B) advertised to adolescents and analyse marketing techniques and persuasive appeals used by celebrities and influencers on Instagram.
Design:
A content analysis study was conducted using the WHO’s CLICK Monitoring Framework and Nutrient Profile Model.
Setting:
Instagram, a popular social media platform among adolescents with frequent F&B advertisements by celebrities and influencers.
Participants:
The top forty-eight Instagram accounts of celebrities and influencers posting F&B advertisements were selected based on follower count and engagement metrics. Nutrient profiling of advertised F&B (n 344) and content analysis of posts featuring F&B (n 326) between January 2021 and May 2023 were performed. Data collected included characteristics of celebrities and influencers, marketing techniques, online engagement and persuasive appeals in the posts.
Results:
Carbonated beverages and flavored waters (28·5 %), energy drinks (20·6 %) and ready-made foods (15·4 %) were most frequently advertised, with the majority (89·2 %) of products not permitted for advertisement to adolescents, according to WHO. Common marketing techniques included tagging brand (96·9 %) and using brand logo (94·2 %). The most frequently used persuasive appeals were taste (20·9 %), energy (10·7 %), link to sports events (10·7 %), new product (9·5 %) and fun (7·4 %).
Conclusion:
Most F&B advertised on Instagram by celebrities and influencers are prohibited from being advertised to adolescents by the WHO. This highlights the need for stricter regulation of user-generated content and for users and parents to be better educated about persuasive techniques used on social media to make them less vulnerable to the influence of marketing.

OBJECTIVE We sought to provide guidelines for the nutritional and endocrine management of adults after bariatric surgery, including those with diabetes mellitus. The focus is on the immediate postoperative period and long-term management to prevent complications, weight regain, and progression of obesity-associated comorbidities. The treatment of specific disorders is only summarized. PARTICIPANTS The Task Force was composed of a chair, five additional experts, a methodologist, and a medical writer. It received no corporate funding or remuneration. CONCLUSIONS Bariatric surgery is not a guarantee of successful weight loss and maintenance. Increasingly, patients regain weight, especially those undergoing restrictive surgeries such as laparoscopic banding rather than malabsorptive surgeries such as Roux-en-Y bypass. Active nutritional patient education and clinical management to prevent and detect nutritional deficiencies are recommended for all patients undergoing bariatric surgery. Management of potential nutritional deficiencies is particularly important for patients undergoing malabsorptive procedures, and strategies should be employed to compensate for food intolerance in patients who have had a malabsorptive procedure to reduce the risk for clinically important nutritional deficiencies. To enhance the transition to life after bariatric surgery and to prevent weight regain and nutritional complications, all patients should receive care from a multidisciplinary team including an experienced primary care physician, endocrinologist, or gastroenterologist and consider enrolling postoperatively in a comprehensive program for nutrition and lifestyle management. Future research should address the effectiveness of intensive postoperative nutritional and endocrine care in reducing morbidity and mortality from obesity-associated chronic diseases.

Malolactic fermentation (MLF) is a biological process of deacidification of wines that may also help to increase the microbiological stability of the product and to enhance its sensorial attributes, in particular its aromatic profile. MLF can occur spontaneously due to the presence of indigenous bacteria in the environment of fermented beverages such as wines and ciders. However, the inoculation of lactic acid bacteria (LAB) starter cultures could prevent potential losses and standardize the process. The industrial-scale production of these starter cultures requires cost-effective, sustainable, and feasible approaches. A possible approach to acquire bacterial biomass, while addressing waste disposal concerns, is the use of by-products from the apple juice industry, such as apple pomace. Moreover, to ensure the long-term viability and activity of starter cultures, appropriate preservation methodologies need to be developed. Thus, the aim of the present study was to evaluate the growth of two <i>Lactiplantibacillus plantarum</i> strains, UNQLp11 and UNQLp155, in supplemented apple pomace and to optimize the preservation conditions. Cultures were either frozen or freeze dried (trehalose (20% m/v) as a protective agent, potassium phosphate buffer (pH 7), and a combination of trehalose and buffer), and then cell viability and malolactic activity were analyzed under wine stress conditions. Notably, the combination of phosphate buffer at pH 7.0 and trehalose emerged as the most effective preservation strategy for freeze drying, exhibiting enhanced viability and malic acid consumption for the two strains evaluated. These findings underscore the inexpensive and sustainable viability of using a semi-solid medium formulated with apple pomace for LAB biomass production and subsequent preservation.

Abstract Background Postmenopausal women are more susceptible to stress urinary incontinence (SUI), and insulin resistance (IR) is closely related to SUI. The triglyceride-glucose (TyG) index is an efficient metric for assessing IR. Investigating whether TyG index and its correlation indexes were correlated with SUI in postmenopausal women was the aim of this research. Methods Data from 2,132 postmenopausal women from the National Health and Nutrition Examination Survey (NHANES) were included in the study for analysis. Weighted multiple logistic regression was used to evaluate the correlation between the TyG index and its correlation indexes and SUI. The nonlinear correlation between the TyG correlation indexes and SUI, as well as the diagnostic efficacy for SUI, was investigated using the smooth curve approach and receiver operating characteristics. Through detailed subgroup analysis, the stability and generalization of the results are confirmed. Results Of the 26.87 million, 13.63 million, or 50.73%, suffered from SUI. The prevalence of SUI was significantly higher in the fourth quartile of TyG-BMI (OR = 1.93, 95% CI 1.13–2.84), TyG-WC (OR = 1.76, 95% CI 1.23–2.51), and TyG-WHtR (OR = 1.81, 95% CI 1.28–2.55) compared to the first quartile. Among the three models, TyG-WHtR always maintained a more significant correlation with SUI (Model 1:OR = 1.30;Model 2:OR = 1.33; Model 3:OR = 1.24). Smooth curve fitting results showed that TyG correlation indexes were not linearly correlated with SUI (P > 0.05). Subgroup analysis further confirmed the reliability and applicability of the results. TyG-BMI had the greatest diagnostic performance for SUI out of the four markers. Conclusions In comparison to TyG, TyG correlation indexes showed a more significant correlation with SUI among postmenopausal women in US, with TyG-BMI showing the best diagnostic effectiveness.
SCOPE This review represents a focus on the structure and properties of the common nutritional disaccharides (lactose, maltose and sucrose) in health and disease. The aim is to provide a comprehensive reference source related to the role of disaccharides in human nutrition. METHODS AND RESULTS Key reference sources were searched including Web of Science, PubMed, Science Direct, Wiley Online etc. and key reference works were selected to support the factual basis of the text where interpretations and relevance of the works were discussed in the review. There are key nutritional health benefits of receiving dietary energy in the form of sugars but equally life-threatening issues exist associated with constant/excess consumption. These issues are discussed together with genetic disorders which impact upon health associated with consumption of the disaccharides (e.g., specific disaccharide intolerance due to deficiency of relevant digestive enzymes). CONCLUSIONS As the three common dietary disaccharides (lactose, maltose and sucrose) are consumed on a very regular basis in the human diet, it is critical to understand insofar as possible their role in health and disease. This review provides an insight into the structure and properties of these molecules in health and disease. This article is protected by copyright. All rights reserved.
Prediabetes is an intermediate stage between normal blood glucose and diabetes and has a high prevalence, especially in older age groups and obese people. Five different definitions are currently used, based on cut-off points for HbA 1C, fasting glucose, and 2-hour glucose. The risks attributable to prediabetes, including diabetes, are related to micro and macrovascular complications, neuropathic complications, cardiorenal diseases, cancer, and death (depending on the definition used).
Data on the worldwide prevalence of prediabetes are incomplete. The International Diabetes Federation (2019) estimated the global prevalence of impaired glucose tolerance at 7.5%. Most people with prediabetes (72.2%) reside in low- and middle-income countries.

Abstract The past two decades have seen a proliferation in bioarchaeological literature on the identification of scurvy, a disease caused by chronic vitamin C deficiency, in ancient human remains. This condition is one of the few nutritional deficiencies that can result in diagnostic osseous lesions. Scurvy is associated with low dietary diversity and its identification in human skeletal remains can provide important contextual information on subsistence strategy, resource allocation, and human‐environmental interactions in past populations. A large and robust methodological body of work on the paleopathology of scurvy exists. However, the diagnostic criteria for this disease employed by bioarchaeologists have not always been uniform. Here we draw from previous research on the skeletal manifestations of scurvy in adult and juvenile human skeletal remains and propose a weighted diagnostic system for its identification that takes into account the pathophysiology of the disease, soft tissue anatomy, and clinical research. Using a sample of individuals from the prehistoric Atacama Desert in Northern Chile, we also provide a practical example of how diagnostic value might be assigned to skeletal lesions of the disease that have not been previously described in the literature.
