Impacts of different pancreatic resection ranges on endocrine function in Suncus murinus

BACKGROUND Surgical intervention involving the pancreas can lead to impaired glucose tolerance and other types of endocrine dysfunction. The scope of pancreatectomy and whether it includes the ventral pancreas are the key factors in the development of postoperative diabetes. The ventral and dorsal pancreases are almost separated in Suncus murinus (S. murinus ). AIM To investigate the effects of different extents of pancreatic resection on endocrine function in S. murinus . METHODS Eight-week-old male S. murinus shrews were randomly divided into three experimental groups according to different pancreatic resection ranges as follows: ventral pancreatectomy (VPx) group; partial pancreatectomy (PPx) group; subtotal pancreatectomy (SPx) group; and a sham-operated group. Postprandial serum insulin, glucagon-like peptide-1 (GLP-1), pancreatic polypeptide (PP), and somatostatin (SST) levels, as well as food intake, weight, blood glucose, and glucose tolerance were regularly measured for each animal. RESULTS S. murinus treated with PPx and SPx suffered from varying degrees of impaired glucose tolerance, but only a small proportion of the SPx group developed diabetes. Only S. murinus in the SPx group showed a significant decrease in food intake accompanied by severe weight loss, as well as a significant increase in postprandial serum GLP-1 levels. Postprandial serum PP levels decreased in both the VPx and PPx groups, but not in the SPx group. Postprandial serum SST levels decreased in both VPx and PPx groups, but the decrease was marginal. CONCLUSION Severe weight loss after pancreatectomy may be related to loss of appetite caused by compensatory elevation of GLP-1. PP and GLP-1 may play a role in resisting blood glucose imbalance.

Increased intake of tree forage by moose is associated with intake of crops rich in nonstructural carbohydrates.

Animals representing a wide range of taxonomic groups are known to select specific food combinations to achieve a nutritionally balanced diet. The nutrient balancing hypothesis suggests that, when given the opportunity, animals select foods to achieve a particular target nutrient balance, and that balancing occurs between meals and between days. For wild ruminants who inhabit landscapes dominated by human land use, nutritionally imbalanced diets can result from ingesting agricultural crops rich in starch and sugar (nonstructural carbohydrates [NCs]), which can be provided to them by people as supplementary feeds. Here, we test the nutrient balancing hypothesis by assessing potential effects that the ingestion of such crops by Alces alces (moose) may have on forage intake. We predicted that moose compensate for an imbalanced intake of excess NC by selecting tree forage with macro-nutritional content better suited for their rumen microbiome during wintertime. We applied DNA metabarcoding to identify plants in fecal and rumen content from the same moose during winter in Sweden. We found that the concentration of NC-rich crops in feces predicted the presence of Picea abies (Norway spruce) in rumen samples. The finding is consistent with the prediction that moose use tree forage as a nutritionally complementary resource to balance their intake of NC-rich foods, and that they ingested P. abies in particular (normally a forage rarely eaten by moose) because it was the most readily available tree. Our finding sheds new light on the foraging behavior of a model species in herbivore ecology, and on how habitat alterations by humans may change the behavior of wildlife.

PACAP ameliorates obesity-induced insulin resistance through FAIM/Rictor/AKT axis.

Obesity and obesity-related insulin resistance have been a research hotspot. Pituitary adenylate cyclase activating polypeptide (PACAP) has emerged as playing a significant role in energy metabolism, holding promising potential for attenuating insulin resistance. However, the precise mechanism is not fully understood. Palmitic acid and a high-fat diet (HFD) were used to establish insulin resistance model in Alpha mouse liver 12 cell line and C57BL/6 mice, respectively. Subsequently, we assessed the effects of PACAP both in vivo and in vitro. Lentivirus vectors were used to explore the signaling pathway through which PACAP may ameliorate insulin resistance. PACAP was found to selectively bind to the PACAP type I receptor receptor and ameliorate insulin resistance, which was characterized by increased glycogen synthesis and the suppression of gluconeogenesis in the insulin-resistant cell model and HFD-fed mice. These effects were linked to the activation of the Fas apoptotic inhibitory molecule/rapamycin-insensitive companion of mammalian target of rapamycin/RAC-alpha serine/threonine-protein kinase (FAIM/Rictor/AKT) axis. Furthermore, PACAP ameliorated insulin resistance by increasing solute carrier family 2, facilitated glucose transporter members 2/4 and inhibiting gluconeogenesis-related proteins glucose 6-phosphatase catalytic subunit 1 and phosphoenolpyruvate carboxykinase 2 expression. Meanwhile, the phosphorylation of hepatic AKT/glycogen synthase kinase 3β was promoted both in vivo and in vitro by PACAP. Additionally, PACAP treatment decreased body weight, food intake and blood glucose levels in obese mice. Our study shows that PACAP ameliorated insulin resistance through the FAIM/Rictor/AKT axis, presenting it as a promising drug candidate for the treatment of obesity-related insulin resistance.

Association between social isolation and diversity in food intake by gender in community-dwelling older adults: A cross-sectional study.

Few studies have investigated the relationship between low dietary variety and clearly defined social isolation by gender. This study explored the association between dietary variety and social isolation, classified by operational definition, separately by gender in community-dwelling older adults. This cross-sectional study recruited respondents via mail. A total of 4798 participants aged ≥65 years participated in the on-site assessment. Social isolation was assessed by "lack of conversation," "lack of passive support," "lack of offering support," and "lack of social participation." Dietary variety was evaluated using the Dietary Variety Score (DVS). The participants' median age was 73 (interquartile range 25-75: 69-77) years, and 2147 (44.7%) were male. After adjusting for covariates, with regard to male participants, a lack of offering support (β = -0.051, P = 0.019) and a lack of social participation (β = -0.089, P < 0.001) were associated with a low DVS. For female participants, only a lack of social participation was related to a low DVS (β = -0.067, P < 0.001). A lack of conversation and passive support were not associated with a low DVS for both genders (P >0.05). The results indicate that encouraging social participation, regardless of gender, as well as preventing a lack of offering support for others among men, may contribute to improving individuals' DVS.

Validity of a digital photo-based dietary assessment tool: Development and initial evaluation.

Background and aim: To evaluate the validity and user satisfaction of a digital photo-based dietary assessment tool as an alternative to the hand-written paper record method that assists researchers during the pandemic. This study compared nutrient intake and users' satisfaction with methods between a digital photo-based dietary assessment tool, known as the Nutrinote Gama app, and food weighing as the gold standard. Methods: Fifty college students majoring in food and nutrition (90% were women; median age, 21 years) took pictures of their foods and beverages before and after consumption and then uploaded them to the Nutrinote Gama application. Trained nutritionists evaluated plate wastes, and nutritional content was revealed on the Nutrinote Gama application. Parallel to the photo-based method, they kept a weight dietary record and sent it to the researcher. A questionnaire was used to assess participants' satisfaction. Results: No statistical differences (p = 0.89) were observed in the measurement of energy intake between Nutrinote Gama (mean ± standard deviation [SD] = 582.8 ± 131) and food weighing (mean ± SD = 566.1 ± 133). No statistical differences (p = 0.59) were also observed in the measurement of protein, fat (p = 0.434), and carbohydrate (p = 230). The energy, protein, fat, and carbohydrate intakes estimated from the two methods were significantly correlated (r = 0.86, 0.870, 0.811, 0.738, respectively). Over 70% of participants were satisfied with the photo-based record. Conclusion: The results indicate that this digital photo-based dietary assessment tool is valid and user-friendly to estimate nutrient intake.

Aggressive behaviour and diabetes: A clinical case of atypical metabolic improvement during clozapine treatment.

Aggressive and violent behaviour is a challenging psychiatric emergency to manage, especially among vulnerable categories such as patients with Intellectual Developmental Disorder. Although there is some evidence that clozapine may be useful as an anti-violence compound, its use is limited by common metabolic complications. An adult patient presented with obesity, type II diabetes mellitus, compulsive food intake, severe Intellectual Developmental Disorder, and a treatment-resistant aggressive behaviour. Clozapine was administered resulting in reduced aggressive behaviour. Unexpectedly, a reduction in the food craving as well as a sustained improvement in both anthropometric parameters and glycemic control were observed during the clozapine treatment. Our case report, describes these findings for the first time, highlighting the need for more clinical research to investigate both the efficacy of clozapine in the Intellectual Developmental Disorder populations and its long-term effects with special regard to the metabolic outcomes in this type of patients.

Irritable bowel syndrome: When food is a pain in the gut.

Irritable bowel syndrome (IBS) is a chronic gastrointestinal condition associated with altered bowel habits and recurrent abdominal pain, often triggered by food intake. Current treatments focus on improving stool pattern, but effective treatments for pain in IBS are still lacking due to our limited understanding of pathophysiological mechanisms. Visceral hypersensitivity (VHS), or abnormal visceral pain perception, underlies abdominal pain development in IBS, and mast cell activation has been shown to play an important role in the development of VHS. Our work recently revealed that abdominal pain in response to food intake is induced by the sensitization of colonic pain-sensing neurons by histamine produced by activated mast cells following a local IgE response to food. In this review, we summarize the current knowledge on abdominal pain and VHS pathophysiology in IBS, we outline the work leading to the discovery of the role of histamine in abdominal pain, and we introduce antihistamines as a novel treatment option to manage chronic abdominal pain in patients with IBS.

Assessment of lifestyle and health-related behaviors and correlates during the COVID-19 pandemic among Lebanese adults

IntroductionThe novel coronavirus disease 2019 (COVID-19) has quickly become a worldwide threat to human health and has significantly impacted people’s lives and changed their lifestyles and health behaviors. This study aims to assess lifestyle and health-related behaviors (LHBs) and associated factors among the general population in Lebanon during the COVID-19 pandemic.MethodsAn online cross-sectional study was conducted among 403 Lebanese adults. The study questionnaire was developed on Google Forms in English and Arabic. It included self-reported questions about sociodemographic characteristics, COVID-19, and perceived behavioral changes (smoking, alcohol consumption, sexual and hygiene behaviors, and intake of nutritional supplements and immunity-boosting foods). It also comprised three scales, i.e., the Lifestyle and Health Behaviors questionnaire (LHB-17), the WHO-5 Well-being Index, and the Fear of COVID-19 scale (FCV-19S).ResultsThe mean age of participants was 29.74 ± 10.81 years, with 51.2% females. Most participants reported that COVID-19 negatively affected their LHBs, mainly diet, sleep, and psychological well-being, while physical activity aspects remained unaffected. Female gender (Unstandardized Beta (ß) = − 2.336), living in Lebanon (ß = − 7.502), nargileh smoking (ß = − 3.433), high BMI (ß = − 0.263), and increased daily usage of electronic devices during the COVID-19 lockdown (ß = − 0.853) were significantly associated with lower LHB-17 scores, indicating worsened LHB. However, living in urban areas (ß = 2.464), employment status (ß = 1.920), good overall health (ß = 3.543), a higher quality of life (ß = 0.204), and unaffected physical (ß = 2.101) and mental (ß = 1.586) health during the COVID-19 lockdown were all significantly associated with higher LHB-17 scores, reflecting positive LHB.ConclusionLebanese adults reported several unfavorable lifestyle changes and psychological problems during the lockdown due to COVID-19, particularly affecting women, non-workers, waterpipe smokers, electronic device heavy users, people of lower socioeconomic status, and those with chronic diseases. Health promotion strategies are needed to assess negative changes both in physical and mental health and maintain as many positive health-related behaviors as possible among the Lebanese population.

The association between ultra-processed food consumption and health-related quality of life differs across lifestyle and socioeconomic strata

BackgroundIn this prospective study, we aimed to examine the association between ultra-processed foods and health-related quality of life (HRQoL) and to evaluate the effect of lifestyle and socioeconomic factors on this association.MethodsThis study included 1766 adults (aged 18 to 78, 54.3% women), who took part in the Tehran Lipid and Glucose study. The Short-Form 12-Item Health Survey version 2 was used to determine HRQoL, which includes the physical component summary (PCS) and mental component summary (MCS) scores. Ultra-processed food consumption was assessed using a validated semi-quantitative food frequency questionnaire. Lifestyle (physical activity and smoking status) and socioeconomic factors (education level and employment status) were also determined. General linear models (GLM) were applied to estimate the mean (95% confidence interval) for MCS and PCS scores across the ultra-processed foods tertiles. Additionally, the effect of lifestyle and socioeconomic factors on the relationship between ultra-processed foods and HRQoL was examined using GLM.ResultsThe median consumption of ultra-processed foods was 11.9% (IQR: 8.2 to 16.8) of total energy intake. There was a significant inverse association between ultra-processed foods consumption and PCS, but not MCS, after adjustment for confounding factors. Significant interactions were observed between ultra-processed food consumption, sex, and occupation on PCS score (all P values < 0.001). The interaction test tended to be significant for smoking status, education levels, and physical activity levels. As ultra-processed food consumption increased, the PCS score significantly decreased in women (P = 0.043), low physical active subjects (P = 0.014), smokers (P = 0.015), and lower-educated individuals (P = 0.022). Non-employed individuals with higher ultra-processed food intake showed a decline in their PCS and MCS scores. While there was no significant difference in MCS score among different strata of lifestyle and socioeconomic status across tertiles of ultra-processed foods.ConclusionsHigher intake of ultra-processed foods was associated with poorer physical health, particularly among women, those with unhealthy lifestyles, and low socioeconomic conditions.

Effect of Moringa, Subabul and Guava Leaves Either Sole or in Combination on Nutrient Utilization, Nitrogen Balance of Ram Lambs

Background: The use of alternate feed resources like tree leaves is key element in addressing the problems derived from climate change and food shortages that demand establishment of sustainable feeding system for ruminants. Methods: A study was conducted on 36 Nellore cross ram lambs (6-7 months; 18.48±0.29 kg BW) randomly allotted to six dietary treatments to evaluate the effect of 20% dietary inclusion of moringa (MOR) subabul (SBL) and guava (GVL) leaves either sole or in combination (MS and MG mixture incorporated at 60:40 and 40:60, respectively) in concentrate mixture on nutrient utilization, plane of nutrition and nitrogen balance. The control group concentrate mixture contained maize, de-oiled rice bran, cotton seed cake and soybean meal as major ingredients and in the 5 experimental concentrate mixtures, de-oiled rice bran and soybean meal were partially replaced with moringa (MOR20), subabul (SBL20), guava (GVL20), moringa and subabul mixture (MS20) and moringa and guava mixture (MG20), by including them at 20%. Animals were fed with respective concentrate mixtures to meet about 80% of protein requirements and sorghum stover was offered ad libitum to meet the nutrient requirements of lambs for maintenance and growth as per ICAR (2013). Result: Dietary inclusion of tree leaves had no effect on the intake of various nutrients viz. DM, OM, CP, EE, CF, NFE, NDF,ADF, Hemicellulose and cellulose and were comparable (P greater than 0.05) among the six dietary groups. The crude protein and crude fibre digestibility improved (P less than 0.01) in tree leaves included diets compared to control, while ether extract (EE) digestibility was lower (P less than 0.01) in tree leaves included diets compared to CON. The DCP, TDN (%) and ME content was higher (P less than 0.05) in MS20, MG20 and MOR20 groups compared to CON. The N intake (g/d), excretion through faeces and urine (g/d), total N excretion and total N balance (g/d) was comparable among the different dietary groups.

Sleep Patterns and Tryptophan Consumption among Students at Spanish Universities: The Unihcos Project

The objective of this cross-sectional study was to explore sleep patterns and the potential relationship between sleep and tryptophan intake among Spanish university students. A total of 11,485 students self-reported their sleep and dietary patterns and habits. Tryptophan intake was calculated using a food intake matrix and results were presented as quartiles of total intake. Short sleep duration prevalence was 51.0%, with males exhibiting a significantly higher frequency. A total of 55.0% of participants presented inadequate sleep efficiency, with males again presenting a higher rate. Median tryptophan intake was 692.16 ± 246.61 mg/day, 731.84 ± 246.86 mg/day in males and 677.24 ± 244.87 mg/day in females (p = 0.001). Dietary tryptophan intake below the first quartile (&lt;526.43 mg/day) was associated with a higher risk of short sleep duration in males (1.26; 95%CI: 1.02–1.55) and females (1.19; 95%CI: 1.05–1.34) and with the Athens Insomnia Scale insomnia in males (2.56; 95%CI: 1.36–4.82) and females (1.47; 95%CI: 1.10–2.05). Regarding academic specializations, females in the humanities field showed a higher risk of Athens Insomnia Scale insomnia due to low tryptophan intake (Q1: 3.15; 95% CI: 1.04–9.55 and Q2: 3.41; 95%CI: 1.01–11.5). In summary, lower tryptophan consumption appears to be associated with poorer sleep quality in Spanish university students; however, other social factors affecting students may also influence sleep quality. These findings have important implications for nutritional recommendations aimed at enhancing tryptophan intake to improve sleep quality.

Deficiency of Energy and Nutrient and Gender Differences among Chinese Adults: China Nutrition and Health Survey (2015–2017)

Half of Chinese adults face the double burden of overweight/obesity and micronutrient deficiencies, and nearly 40% of them are severely overweight/obese or have micronutrient deficiencies. This study used the data from China Nutrition and Health Survey (CNHS) from 2015 to 2017 to estimate the prevalence of inadequate dietary micronutrient intake (including vitamin A, vitamin B1, vitamin B2, vitamin C, cCalcium, iron and sodium) in Chinese adults and further determine the differences in micronutrient intake by gender, age and BMI. A total of 61,768 subjects were included in this study, of which 33,262 (54%) were female. The intake of energy and all macronutrients decreased with age, and the intake was higher in men than in women. Inadequate energy intake occurs in adults of all ages. In terms of nutrient intake, women had a higher rate of insufficient carbohydrate intake than men in all age groups. Inadequate protein intake was more common in women aged 18–49 years (60.9%) than in men. Compared with women, men had a higher rate of vitamin B2 intake. Insufficient vitamin B3 intake was more common in women aged 18–49 years (35.6%), men aged 65–79 years (39.7%) and men aged 80 years and above (47.9%). In all age groups, insufficient vitamin C intake is higher in women than in men—up to 85.8 percent in women aged 80 years old and above. Compared with men in the same age group, insufficient intake of calcium and iron is more obvious in women. Women have significantly higher rates of inadequate intake of calcium, iron and sodium than men. In the analysis of correlations between BMI or demographic data and micronutrient intakes, the likelihood of micronutrient intakes being insufficient was higher in the central and western regions in all age groups compared to the eastern regions. The risk of insufficient micronutrient intake was higher in obese men and women aged 18–49 years and 50–64 years. Underweight and overweight women in the 65–79 age group were more likely to have inadequate micronutrient intake. Obese women over 80 years of age were less likely to have inadequate micronutrient intake. No significant difference was found between urban and rural areas for each age group.

Effects of early monocular enucleation on cortical spreading depression in well-nourished and malnourished adult rats.

Sensory development is a complex process that can influence physiological and pathological factors. In laterally-eyed mammals, monocular enucleation (ME) during development and the subsequent lack of external sensory stimuli can result in permanent morphological and physiological changes. Malnutrition, especially in early life, also can cause permanent morphofunctional changes due to inadequate nutrient intake in both hemispheres. This study investigated the effects of early (postnatal day 7) ME and malnutrition during the suckling period on cortical excitability in adulthood (110-140 days of life). For this, we compared the speed propagation of cortical spreading depression in the occipital and parietal cortex of malnourished and well-nourished adult rats, previously suckled small-sized litters with three pups (L3/dam) medium-sized litters with six pups (L6/dam), and large-sized litters with twelve pups (L12/dam). The CSD velocity was augmented by the ME in the contralateral side of the removed eye in the parietal and occipital cortex. These findings suggest that visual sensory input deprivation is associated with permanent functional changes in the visual pathways, which can alter cortical excitability and lead to modifications in CSD propagation.

Refeeding hypophosphatemia is a common cause of delirium in critically ill patients: A retrospective study

BackgroundThe purpose was to explore the correlation between refeeding hypophosphatemia and delirium and analyze the related factors in critically ill patients. MethodsWe conducted a retrospective review of critically ill patients admitted to Nanjing Drum Tower Hospital between September 2019 and March 2021. The patients were divided into delirium and nondelirium groups. Demographic data, underlying diseases, laboratory findings, comorbidities, nutritional intake and overall prognosis were collected and analyzed. ResultsIn total, 162 patients were included and divided into delirium (n = 54) and nondelirium (n = 108) groups. Serum phosphorus levels in the two groups decreased significantly in the first three days (P1, P2, P3) after nutrient intake compared with baseline before nutrient intake (Ppre). P1 and P2 were significantly lower in the delirium group compared to the nondelirium group. The maximum blood phosphorus reduction (Pmax) in the first three days after nutrient intake was significantly higher in the delirium group than in the nondelirium group. The time of Pmax in the delirium group was on the first day after nutrient intake. Multivariable logistic regression analysis identified starting route of nutrition and P1< 0.845 mmol/L as the independent predictors of delirium development in critically ill patients. ConclusionThe incidence of delirium in critically ill patients is high and associated with refeeding hypophosphatemia. Delirium may occur with serum phosphorus levels less than 0.845 mmol/L on the first day.

Hippocampus oxytocin signaling promotes prosocial eating in rats

Oxytocin (OT) is a hypothalamic neuropeptide involved in diverse physiological and behavioral functions, including social-based behavior and food intake control. The extent that OT's role in regulating these two fundamental behaviors is interconnected is unknown and is a critical gap given that social factors have a strong influence on eating behavior in mammals. Here we focus on OT signaling in the dorsal hippocampus (HPCd), a brain region recently linked with eating and social memory, as a candidate system where these functions overlap. HPCd OT signaling gain- and loss-of-function strategies were employed in male Sprague-Dawley rats that were trained in a novel social eating procedure to consume their first nocturnal meal under conditions that vary with regards to conspecific presence and familiarity. The endogenous role of HPCd OT signaling was also evaluated for olfactory-based social transmission of food preference learning, sociality, and social recognition memory. HPCd OT administration had no effect on food intake under isolated conditions, yet significantly increased consumption in the presence of a familiar, but not an unfamiliar conspecific. Supporting these results, chronic knockdown of HPCd OT receptor expression eliminated the food intake-promoting effects of a familiar conspecific. HPCd OT receptor knockdown also blocked social transmission of food preference learning and impaired social recognition memory without affecting sociality. Collective results identify endogenous HPCd OT signaling as a novel substrate where OT synergistically influences eating and social behaviors, including the social facilitation of eating and the social transmission of food preference.

The odds of having obesity in Egyptian children with autism spectrum disorders is higher than stunting compared to healthy developing peers: a national survey

BackgroundThe nutritional status and growth of children with Autism spectrum disorders (ASD) is influenced significantly by two factors; food selectivity behaviors due to their consumption of a limited variety of food and the high incidence of gastrointestinal (GIT) disorders.AimThis study aimed to assess the nutritional adequacy and growth pattern of ASD children aged three to twelve years compared to their healthy developing peers.MethodsA national comparative, facility-based cross-sectional study was conducted in eight Egyptian governorates on 285 Egyptian children diagnosed with ASD and 224 children who are their relatives as healthy developing peers. Anthropometric measurements were obtained, including weight, height, head circumference, and mid-upper arm circumference. Body Mass Index (BMI) was calculated and all numbers were plotted on WHO growth charts. Assessment of food preferences, and nutrient intake adequacy of children was done using the Food preference questionnaire, and the Dietary Reference Intakes (DRIs) of Egyptian children.ResultsCalorie-dense food and sugar intake were higher among ASD children than their healthy developing peers. ASD children omit some important protein sources such as dairy (COR = 5.2, 95% CI:2.7–9.9), meat, and poultry (COR = 2.7, 95% CI: 1.6–4.7), and a lower intake of fruits and vegetables than their healthy developing peers. For children with ASD in all age groups, a deficiency in the range of 50–60% was detected for vitamins (C, D, B6, thiamine, riboflavin, niacin) and minerals (iron). A deficiency in the range of 60–70% was detected for folate and calcium. A deficiency of vitamin C calcium and iron was also detected for both children with ASD and their healthy developing relatives aged 6 to 12 years. GIT disorders were common among ASD children compared to healthy developing peers (COR = 2.8 to 10.3). Children with ASD had four-fold higher odds of stunting (COR = 4.1, CI: 1.7–10.1), threefold higher odds of being overweight (COR = 3.3, CI: 1.48–7.32), and nearly eleven-fold higher odds of obesity (COR = 11.4, CI: 4.05–32.17) compared to their healthy developing peers.ConclusionASD children are prone to overweight and protein malnutrition. Their intake of fruits and vegetables is inadequate and hence their intake of vitamins and minerals is insufficient, contributing to stunting.

Environmental burden of excessive food intake: Exploring new opportunities to enhance food and environmental sustainability in China

China faces increasing challenges in producing sufficient food sustainably while confronting a worsening overweight and obesity crisis caused partly by overeating. Building on the China Health and Nutrition Survey data, this study estimated the agricultural and environmental implications of overeating based on human metabolic theory and life cycle assessment. The results show that the average excess food intake per person is twice the amount of household edible food waste (53.85 vs. 26.88 g/capita/day). The total excessive food intake is equivalent to 18.7 Mt of annual cereal production, approximately 4.3 times China's recent annual cereal production growth (4.4 Mt). Excessive food intake also embodies substantial carbon, water, energy, and ecological footprints, amounting to 39.15 Mt CO2e, 31.40 Gm3, 11.18 Mtce, 544.69 × 108 gm2, respectively, significantly exceeding the corresponding domestic food waste footprints. Cereals and meats have a dominant role in excessive food intake and related environmental impacts, with significant differences linked to demographic characteristics and urbanization levels. China has implemented various national policies, including an anti-food-waste law, to address agri-food sustainability challenges. This study suggests that addressing overeating can significantly enhance China's ability to tackle these challenges and improve public health outcomes.

Curbing the Obesity Epidemic: Should GLP-1 Receptor Agonists Be the Standard of Care for Obesity?

This article summarizes the medical management of obesity with an emphasis on incretin-based therapeutics that target the neuro-hormonal basis of obesity. Medications that mimic the effect of incretins, a group of peptide hormones released in response to nutrient intake that regulate appetite, result in potent and durable weight loss. Glucagon-like peptide 1 (GLP-1) agonists and glucose-dependent insulinotropic polypeptide (GIP) agonists such as semaglutide and tirzepatide are approved by the United States Food and Drug Administration (FDA) for the management of obesity. The SELECT trial demonstrated that semaglutide led to a reduction in major adverse cardiovascular events in patients without diabetes who were either overweight and had preexisting cardiovascular disease or obese. The treatment of obesity is critical to prevent the progression of cardiovascular-kidney-metabolic syndrome. Incretin-based therapies offer remarkable weight loss and reduce major cardiovascular adverse events.

ARFID Parent Training Protocol ("ARFID-PTP"): Results of a Randomized Pilot Trial Evaluating a Brief, Parent-TrainingProgram for Avoidant/Restrictive Food Intake Disorder.

Accessible treatment options for avoidant/restrictive food intake disorder (ARFID) in children are limited. The current study sought to assess acceptability, feasibility, and preliminary efficacy of a brief, virtual intervention for ARFID in children ("ARFID-PTP"). Families of children ages 5-12 with ARFID (n = 30) were randomized to immediate or waitlist treatment groups, with both groups ultimately receiving ARFID-PTP. ARFID-PTP consists of two, 2-h individual treatment sessions with an optional booster session at 4-week follow-up. Families completed acceptability and feasibility measures at end-of-treatment, as well as preliminary efficacy measures at 4-week, 3-month, and 6-month follow-up. Of 30 families who completed an intake session, 27 (90%) completed treatment. Families rated acceptability as high (MCEQ-C = 7.75). Treatment was feasible by participant retention. Exposure adherence was lower than expected, and booster session requests were higher than expected, indicating that achieving feasibility across measures may require treatment modifications. Regarding preliminary efficacy, children in the immediate treatment group had a decrease in ARFID symptoms compared to those on the waitlist. Overall, at 6-month follow-up linear mixed models showed participants had significantly reduced ARFID symptoms by presentation (p < 0.05) and in follow-up completers, children incorporated eight new foods on average. ARFID-PTP is acceptable and preliminarily efficacious. The protocol may benefit from modifications to increase feasibility; however, booster session content and treatment outcomes suggest a priori feasibility markers may not accurately capture the utility of ARFID-PTP. Further work should continue to examine the efficacy ARFID-PTP, particularly in diverse samples where treatment accessibility is urgently needed. ClinicalTrials.gov identifier: NCT04913194.
