Water Consumption: Effect on Energy Expenditure and Body Weight Management.

Water, which is of vital importance, has a critical role in maintaining the normal function of the body, and even mild dehydration can play a role in the development of various diseases. Therefore, it is of great importance to meet the recommended daily water consumption amounts. In addition to the numerous roles of water in metabolism, its effect on energy metabolism should not be overlooked. Water consumption can increase energy expenditure and be an additional tool for weight management. Therefore, the importance of water consumption, which is like a hidden component for treating of obesity, should be emphasized. This review was written to explain the possible mechanisms of water consumption in energy expenditure and body weight management. Because water consumption is associated with sympathetic activity, which increases metabolic rate (thermogenesis) and daily energy expenditure, the increase in sympathetic activity caused by water consumption is an important and unrecognized component of daily energy expenditure. In addition to the concept of water-based thermogenesis, water, which is a potential improvement factor in body composition, also plays an auxiliary role in body weight loss with both less energy intake and increased fat oxidation. From this perspective, water consumption may have critical importance in the fight against increasing obesity worldwide. Considering its effect on energy metabolism in various ways, it becomes necessary to focus more on the importance of water on human health. (Created by BioRender.com).

Combined treatment with teneligliptin and canagliflozin additively suppresses high-fat diet-induced body weight gain in mice with modulation of lipid metabolism-related gene expression

In the treatment of type 2 diabetes mellitus (T2DM), comprehensive management of multiple risk factors, such as blood glucose, body weight, and lipids, is important to prevent disease progression. Although the combination of dipeptidyl peptidase-4 (DPP-4) inhibitor and sodium-glucose co-transporter 2 (SGLT2) inhibitor is often used clinically, the effects of this combination, other than glucose metabolism, have yet to be thoroughly investigated. In this study, we evaluated the effects of combined treatment with a DPP-4 inhibitor, teneligliptin, and an SGLT2 inhibitor, canagliflozin, on the body weight and lipid metabolism in high-fat diet (HFD)-induced obese mice. We found that monotherapy with teneligliptin or canagliflozin showed suppressive effects on high-fat diet-induced body weight gain and reduced inguinal white adipose tissue (iWAT) mass, and combined treatment additively reduced body weight gain and iWAT mass. Teneligliptin significantly increased oxygen consumption during the light phase, and this effect was preserved in the combined treatment. The combined treatment did not alter the mRNA expression levels of thermogenesis-related genes in adipose tissue but showed the tendency to additively induce mRNA of fatty acid oxidation-related genes in brown adipose tissue and tended to additively decrease mRNA of fatty acid synthesis-related genes in iWAT and liver tissues. These results suggest that combined treatment with teneligliptin and canagliflozin additively suppresses HFD-induced body weight gain with increasing oxygen consumption and modulating the expression of lipid metabolism-related genes. This combination therapy may provide effective body weight management for patients with T2DM and obesity.

“In China, I live to eat. Here, I eat to live”

The population of international students in Canadian post-secondary institutions, including in dietetic programs, is growing. In addition to academic stress, international students must cope with culture change and acculturative stress, which has been found to increase the prevalence of problematic eating and body image concerns among this population. Research indicates that problematic eating and body image concerns may also be relatively high among dietetic students due, in part, to the emphasis on body weight management and the narrow representations of healthy eating, and the disciplinary processes of professional socialization that are characteristic of dietetic education. For international dietetic students, vulnerability to problematic eating and body image concerns may be particularly acute, given their position as both dietetic and international students. However, little is known about the experiences of this population, and if, how and to what extent being an international dietetic student may impact on eating and body image concerns, or what efforts may be needed to prevent and support those experiencing these concerns. This research used the EAT-26 questionnaire and one-on- one, semi-structured interviews to explore how culture change impacts eating and body image among Mandarin-speaking, Chinese international dietetic students. Results indicate that culture change has a significant impact on the relationships to food and on eating and body image among the study population. Further research is needed to elucidate the impacts of culture change, and how dietetic educators may best support international dietetic students.

Does the Nature of Added Bioactive Lipids Affect the Biological Properties of Yogurts?—Case Study Coconut and Avocado Oils

Bioactive lipids play an important role in human health and their benefits are linked to their chemical nature; for example, medium-chain fatty acids can have an important contribution to body weight management. This work aimed to test a strategy to enhance the quality profile and gastrointestinal tract resistance of previously developed vegetable oil-functionalized yogurts and further probe the biological potential of functionalized yogurts. Fortification with coconut and avocado vegetable oils led to increased nutritional value through an increase in essential fatty acids content, particularly in yogurts with vegetable oil bigels. One of the main problems with bioactive fatty acids fortification is their poor stability during in vitro digestion and consequently poor bioavailability. Despite this, the digested samples decreased lipid accumulation in Hep G2 and 3T3-L1 cells Functionalized yogurts were also responsible for high improvements in adiponectin secretion (35% for COY, 46% for CBY, 53% for AOY, and 48% ABY) compared with control yogurt. Moreover, in the inflammatory model, a reduction between 30% (for control yogurt) and 70% (for CBY) was observed for IL-6 secretion in LPS-stimulated cells. Considering these results, yogurt’s fortification with vegetable oils can be a viable alternative strategy to be scaled up for obesity management.

Targeting carnitine palmitoyltransferase 1 isoforms in the hypothalamus: A promising strategy to regulate energy balance.

Tackling the growing incidence and prevalence of obesity urgently requires uncovering new molecular pathways with therapeutic potential. The brain, and in particular the hypothalamus, is a major integrator of metabolic signals from peripheral tissues that regulate functions such as feeding behavior and energy expenditure. In obesity, hypothalamic capacity to sense nutritional status and regulate these functions is altered. An emerging line of research is that hypothalamic lipid metabolism plays a critical role in regulating energy balance. Here, we focus on the carnitine palmitoyltransferase 1 (CPT1) enzyme family responsible for long-chain fatty acid metabolism. The evidence suggests that two of its isoforms expressed in the brain, CPT1A and CPT1C, play a crucial role in hypothalamic lipid metabolism, and their promise as targets in food intake and bodyweight management is currently being intensively investigated. In this review we describe and discuss the metabolic actions and potential up- and downstream effectors of hypothalamic CPT1 isoforms, and posit the need to develop innovative nanomedicine platforms for selective targeting of CPT1 and related nutrient sensors in specific brain areas as potential next-generation therapy to treat obesity.

Continuous exposure to red light induces photorefractoriness in broiler breeder pullets

The management of body weight (BW) in broiler breeder pullets is critical to offset the negative correlation between their growth potential and reproductive success. Therefore, a precision feeding system was developed to allocate feed individually based on real-time BW in more frequent, smaller portions. However, this system requires access beyond the 8 h daylength of the rearing period. Since green and red spectra have been shown to stimulate growth and sexual maturation, respectively, this study aimed to evaluate the impact of continuous supplemental illumination of feeders with monochromatic wavelengths on sexual maturation. Furthermore, the best combination of supplemental and daytime lighting for optimizing the pullet-to-hen transition period was investigated. This study contained a 2×4×2 factorial arrangement, with 2 daytime lights (dtRED and dtGREEN; n=2 rooms), 4 supplemental lights (sBLUE, sGREEN, sRED, and sCON; n=12 pens), and 2 supplemental intensities (High and Low). At 3 wk of age (woa), 480 female Ross 708 chicks were randomly distributed across treatments (n=10/pen). All birds were feed restricted per management guidelines and maintained under 8 h of dtRED or dtGREEN. Birds were photostimulated at 20 woa with 14L:10D. All birds were weighed weekly, with age at first egg (AFE) and production rate calculated weekly per pen. Birds under sRED were heavier than all other treatments from 27 woa to the end of the study (P < 0.001; 30 woa), resulting in hens that were over 400-g heavier. This resulted from a delayed AFE and lower production rate under sRED, with higher intensity further hindering reproductive performance (P < 0.001). Interestingly, despite the inhibitory effect of continuous red lighting (sRED) on reproduction, dtRED resulted in a 3.15% higher rate of lay than dtGREEN. Therefore, this study suggests that while red light remains superior at stimulating reproduction, continuous red supplemental lighting results in photorefractoriness. Thus, we recommend green light in PF systems.

Low glycemic index common bean snack increased satiety without modifying energy intake in adults with normal weight: randomized crossover trials

This study aimed to evaluate the short-term effect of a common bean baked snack (CBBS) and cooked bean consumption on energy intake, satiety, glycemic response, and palatability in subjects with normal weight (Study 1) and overweight (Study 2) and to determine the glycemic index of CBBS (Study 3). For studies 1 and 2, satiety and glycemic response were measured over 45 min after consuming CBBS, cooked beans or white bread preload, and energy intake at an ad libitum test meal was calculated. Energy intake remained similar after consuming the three preloads in both studies. Compared to white bread, CBBS consumption increased fullness by 52% in subjects with normal weight but not in those with overweight. The CBBS calculated glycemic index was considered low (42). Consumption of low glycemic index CBBS increased satiety in adults with a normal weight. Long-term trials assessing the effects on body weight management are necessary.

Associations between dietary variety, portion size and body weight: prospective evidence from UK Biobank participants.

'Dietary variety' has been identified as a factor associated with food intake. Whilst this relationship may have longer-term benefits for body weight management when eating low-energy, nutrient-dense foods, it may increase the risk of overconsumption (and body adiposity) when foods are high energy density. This study sought to further explore pathways underpinning the relationship between dietary variety and body weight, by considering energy density as a moderating factor and portion size as a mediating factor in this relationship. Using prospective data from the UK Biobank, dietary variety scores (DVS), cumulative portion size and energy density were derived from 24-h dietary recall questionnaires at baseline and follow-up. BMI, whole-body fat percentage and fat-free mass were included as outcomes. Contrary to predictions, linear multiple regression models found some evidence of a negative, direct association between DVS and body weight outcomes at baseline (b = -0·13). Though dietary variety was significantly associated with larger portions across time points (b = 41·86-82·64), a moderated mediation effect was not supported at baseline or follow-up (Index ≤ 0·035). Taken together, these findings provide population-level evidence to support a positive association between variety and food intake, which in turn has potential implications for body weight management, both in terms of moderating food intake and benefitting diet quality.

Methodological Quality of Systematic Reviews on Bodyweight Management Strategies for Children and Adolescents.

Systematic reviews (SRs) synthesize empirical evidence from randomized controlled trials, to answer a research question. Methodological flaws in SRs can, however, reduce the trustworthiness of conclusions, subsequently hindering decision making. We aimed to appraise the methodological quality of existing SRs on bodyweight management strategies for children and adolescents. We searched Cochrane Database of Systematic Reviews, MEDLINE, EMBASE, and SPORTDiscus. A MeaSurement Tool to Assess systematic Reviews (AMSTAR 2) was used to evaluate the methodological quality of SRs including 16 individual AMSTAR 2 domains and the total AMSTAR score. Association between bibliographical characteristics and total AMSTAR score of SRs was explored using multiple linear regression analysis. Three critical domain-specific items of AMSTAR 2 among the included SRs showed unsatisfactory results including (i) justifying deviation from their SR protocols, (ii) using comprehensive literature search strategies, and (iii) giving details of both included and excluded studies. "More recent publication year journal," "higher impact factor of the journal," and "greater number of review authors" were associated with better methodological quality of the included SRs. Future SRs' authors in the field of bodyweight management strategies for children and adolescents should improve the following criteria: (i) justify deviations from SR protocol, (ii) explain selection of the included study designs, (iii) use comprehensive literature search strategy, (iv) give details for both included and excluded studies, (v) report funding sources among included studies, and (vi) assess the potential impact of risk of bias among the included studies on meta-analysis results.

ФАКТОРЫ РИСКА УВЕЛИЧЕНИЯ ОБЪЕМА ЛЕКАРСТВЕННОЙ ТЕРАПИИ У ПЕДИАТРИЧЕСКИХ ПАЦИЕНТОВ С БРОНХИАЛЬНОЙ АСТМОЙ (ПО РЕЗУЛЬТАТАМ ДЕСЯТИЛЕТНЕГО ПРОСПЕКТИВНОГО НАБЛЮДЕНИЯ)

The study aims to determine the anamnestic, functional, and laboratory factors affecting the load of basic drug therapy in children with bronchial asthma during a ten-year regular dynamic monitoring of their height, body weight, spirometry data, the nature of the ongoing treatment of asthma, and the drug doses. An open, prospective monitoring trial included 131 patients, each of whom attended a hospital at least 20 times every 6 months. The data obtained was not used to correct the therapy method and regular medical check-up. By the end of the tenth year, 98 patients had demonstrated the following results: 57.1 % of children maintained a stable load of basic therapy, while the load of drug therapy was increased in 24.5 % of patients, and decreased in 18.4 % of them. The likelihood of a drug load reduction was statistically significantly reduced in patients with a body mass index greater than 90 weight percentile for 18 months or longer in comparison with patients who had never been overweight. Patients with the obstructive disorders detected with spirometry during two or more consecutive visits had a statistically significantly higher risk of drug therapy overload or a lower likelihood of its reduction in comparison with those without any external respiration malfunctions. The allergen-specific therapy made it possible to significantly lower the risk of drug overload and increase the possibility of its reduction. The allergen-specific immunotherapy, body weight management, and absence of obstructive disorders in spirometry all contribute to reducing the drug therapy load while maintaining a controlled course of the disease.

Prevalence of obesity and hypertension in the region of Khouribga (Morocco): Effects of socio-demographic and lifestyle factors

Obesity is characterized by an excessive accumulation of body fat is in continuous increase associated with cardiovascular risks and health disadvantages. Objective: The aim was to the study the prevalence and the determining factors of the association of obesity and hypertension in the Moroccan population of Khouribga province hitherto unstudied. A cross-sectional survey was conducted oi 2019 among a random sample of 401 adults of both sexes, from urban and rural areas. Anthropometric parameters and blood pressure were measured. Body mass index (BMI), waist-to-hip ratio (WHR), were calculated, Socio-demographic characteristics and physical activity level are determined. Anthropometric variables are significantly different in women and men. General obesity (BMI&gt;30) was prevalent in 33.1% and abdominal obesity in more than 75%. Both general and abdominal obesity do not show any significant difference between urban and rural areas of residence. Hypertension was present in 35.5% in both sexes, significantly higher in rural men (57%) compared to urbans. Obesity increases with sedentarity. Obesity and hypertension increase with age and manifest themselves beyond the age of 35. Women with more than three children are obese. The present study data show that body weight management is related to origin, age, number of children as parameters associated with obesity. The prevalence of hypertension is associated with severe obesity. Abdominal obesity could be a predictive parameter of hypertension in the Moroccan population of the study province.

PS-P12-1: SELF-CARE MANAGEMENT FOR HYPERTENSION IN SOUTHEAST ASIA: A SCOPING REVIEW

Objective: This scoping review aims to explore the current state of self-care management practices used by hypertension populations based on evidence from the existing scientific literature for SEA. Self-care practices such as lifestyle modifications in diet, exercise, and stress management, are effective in reducing the incidence of and enhancing better management of hypertension. However, little is known about the self-care management practices of people with hypertension in Southeast Asia (SEA) countries where the prevalence of hypertension is sharply increasing. Design and method: A scoping review of research and grey literature (2006–2021) was performed using Scoping Review Frameworks by Arkey and O Malley. For the research literature, ten databases were searched followed by a manual search of the reference lists of relevant topical papers. Results: Results indicate that bodyweight management, physical exercise, dietary intake, and medication adherence were largely poorly practiced by hypertensive people. Stress-relieving methods such as sleep, rest, and spiritual fulfilment was described as alternative self-care management methods. Anecdotal evidence of factors that facilitated or inhibited the implementation of self-care practices were described. Conclusion: While the overall evidence review suggests that hypertensive people in SEA do not adequately implement self-care to better manage hypertension, the anecdotal information provided by several reports indicate that there is individual variation in the facilitators and barriers to implementing self-care practices. The facilitators and barriers are relevant to personal choice [internal factors] or to the environment or context [external factors]. Enhancing self-care management of hypertension in SEA may require a multi-focused approach including targeting personal choice as well as external factors such as cultural relevance, environment and resources. Health workers working in the community in SEA countries should consider a multi-focused approach and cultural aspect in helping hypertensive patients to manage their self-care.

Body image dissatisfaction, nutritional status and weight control strategies among university undergraduates in Lagos: a descriptive cross-sectional study.

body image dissatisfaction has been associated with poor nutritional status and unhealthy weight management strategies. This study determined the prevalence and relationships between body image dissatisfaction, nutritional status, and weight management strategies among university undergraduate students in Lagos, Nigeria. a descriptive cross-sectional study employed a multi-stage sampling technique to select 865 undergraduates in Lagos. A pretested self-administered questionnaire was used to assess the variables. Stunkard figure rating scale was used to determine body image dissatisfaction. Body mass index (BMI) was calculated to determine nutritional status. A standard weight control strategy scale was adopted to determine weight management strategies. SPSS (version 23) was used for analysis and the association between variables was determined using Chi-square. The level of significance was set at P= <0.05. the prevalence of body image dissatisfaction was high (63.5%) but not associated with gender. The majority (65.1%) had normal BMI, 10.6% were overweight and 7.2% were obese. Majority of the respondents (93.3%) engaged in weight management practices with dietary control being the most employed strategy. The most commonly employed unhealthy practice is strict dieting (37.7%). Body image dissatisfaction was significantly associated with overweight/obesity (P=0.001) but not with weight management practices. Age and overweight/obesity were predictors of BID. prevalence of body image dissatisfaction, overweight and obesity, and unhealthy weight management strategies were high. Body image dissatisfaction was associated with obesity but not associated with weight management strategies. All undergraduates need health education on body image and appropriate weight management strategies.

Barriers and facilitators of healthy lifestyle and perspectives towards the development of weight loss programmes. Focus groups with post-treatment breast cancer survivors in Greece.

The present study aimed to identify the factors that prohibit or enable breast cancer survivors from adopting a healthy lifestyle, as well as to record patients' suggestions towards developing a weight-loss lifestyle intervention. Twenty-three breast cancer survivors participated in four online, semi-structured focus groups in Greece. All discussions were video-recorded and transcribed verbatim. Participants were 50⋅5 ± 7⋅4 years old with a current mean BMI of 29⋅1 ± 3⋅4 kg/m2. Four main themes emerged from thematic analysis: (1) dietary and lifestyle practices, (2) the effects of cancer on body weight, (3) the impact of cancer on psychology, and (4) the effect of the environment on body weight. Lack of information from healthcare professionals and lack of time were the main barriers to body weight management, whereas the main facilitators were support from their social environment, along with a comfortable physical environment, and the facility of technology. Participants suggested that an effective weight-loss lifestyle intervention should include psychological and social support, guidance and education, collaboration, flexible recommendations, personalised goals, and a follow-up plan. The needs of breast cancer survivors need to be considered when designing weight-loss lifestyle interventions. A personalised approach may prove more effective in promoting a healthy lifestyle and improving patients' care.

Enhanced secretion of satiety-promoting gut hormones in healthy humans after consumption of white bread enriched with cellular chickpea flour: A randomized crossover study

BackgroundDietary intake of pulses is associated with beneficial effects on body weight management and cardiometabolic health, but some of these effects are now known to depend on integrity of plant cells, which are usually disrupted by flour milling. Novel cellular flours preserve the intrinsic dietary fiber structure of whole pulses and provide a way to enrich preprocessed foods with encapsulated macronutrients. ObjectivesThis study aimed to determine the effects of replacing wheat flour with cellular chickpea flour on postprandial gut hormones, glucose, insulin, and satiety responses to white bread. MethodsWe conducted a double-blind randomized crossover study in which postprandial blood samples and scores were collected from healthy human participants (n = 20) after they consumed bread enriched with 0%, 30%, or 60% (wt/wt) cellular chickpea powder (CCP, 50 g total starch per serving). ResultsBread type significantly affected postprandial glucagon-like peptide-1 (GLP-1) and peptide YY (PYY) responses (time × treatment, P = 0.001 for both). The 60% CCP breads elicited significantly elevated and sustained release of these anorexigenic hormones [between 0% and 60% CPP—GLP-1: mean difference incremental area under the curve (iAUC), 3101 pM/min; 95% CI: 1891, 4310; P-adjusted < 0.001; PYY: mean difference iAUC, 3576 pM/min; 95% CI: 1024, 6128; P-adjusted = 0.006] and tended to increase fullness (time × treatment, P = 0.053). Moreover, bread type significantly influenced glycemia and insulinemia (time × treatment, P < 0.001, P = 0.006, and P = 0.001 for glucose, insulin, and C-peptide, respectively), with 30% CCP breads eliciting a >40% lower glucose iAUC (P-adjusted < 0.001) than the 0% CCP bread. Our in vitro studies revealed slow digestion of intact chickpea cells and provide a mechanistic explanation for the physiologic effects. ConclusionsThe novel use of intact chickpea cells to replace refined flours in a white bread stimulates an anorexigenic gut hormone response and has potential to improve dietary strategies for prevention and treatment of cardiometabolic diseases.This study was registered at clinicaltrials.gov as NCT03994276.

Effects of acute exercise and exercise training on plasma GDF15 concentrations and associations with appetite and cardiometabolic health in individuals with overweight or obesity – A secondary analysis of a randomized controlled trial

Growth Differentiation Factor 15 (GDF15) is seemingly involved in appetite control. Acute exercise increases GDF15 concentrations in lean humans, but acute and long-term effects of exercise on GDF15 in individuals with overweight/obesity are unknown. We investigated the effects of acute exercise and exercise training on GDF15 concentrations in individuals with overweight/obesity and associations with appetite and cardiometabolic markers. 90 physically inactive adults (20–45 years) with overweight/obesity were randomized to 6-months habitual lifestyle (CON, n=16), or isocaloric exercise of moderate (MOD, n=37) or vigorous intensity (VIG, n=37), 5 days/week. Testing was performed at baseline, 3, and 6 months. Plasma GDF15 concentrations, other metabolic markers, and subjective appetite were assessed fasted and in response to acute exercise before an ad libitum meal. Cardiorespiratory fitness, body composition, insulin sensitivity, and intraabdominal adipose tissue were measured. At baseline, GDF15 increased 18% (95%CI: 4; 34) immediately after acute exercise and 32% (16; 50) 60 min post-exercise. Fasting GDF15 increased 21% (0; 46) in VIG after 3 months (p=0.045), but this attenuated at 6 months (13% (−11; 43), p=0.316) and was unchanged in MOD (11% (−6; 32), p=0.224, across 3 and 6 months). Post-exercise GDF15 did not change in MOD or VIG. GDF15 was not associated with appetite or energy intake. Higher GDF15 was associated with lower cardiorespiratory fitness, central obesity, dyslipidemia, and poorer glycemic control. In conclusion, GDF15 increased in response to acute exercise but was unaffected by exercise training. Higher GDF15 concentrations were associated with a less favorable cardiometabolic profile but not with markers of appetite. This suggests that GDF15 increases in response to acute exercise independent of training state. Whether this has an impact on free-living energy intake and body weight management needs investigation.

A randomized controlled study to evaluate the effects of lifestyle intervention program for patients with severe mental illness taking Second Generation Antipsychotics (SGAs) in body weight management and monitoring their Body Mass Index (BMI)

Background: Second generation antipsychotics (SGAs) are strongly associated with accelerated body weightgain resulting in overweight and obesity in patients with severe mental illness (SMI). Evidence found that lifestyleinterventions used behavioral techniques to improve dietary habits and increase physical activity can reduce the increasein patients’ body weight and BMI. Methods: Randomized Controlled Trial (RCT) on 54 patients with severe mental illnesswere randomized with 27 patients joined in the Lifestyle Intervention group (LIP) and 27 patients in treatment as usual group(TAU) from September/2018 to October/2019. The intervention group attended the educational talks on medication, dietcontrol and physical exercise and use of a daily record. Result: After twelve months, the LIP presented a decrease of 1.25kg(CI 95% -0.73 to 3.24) and treatment as usual TAU presented with a significant increase of 1.65kg CI 95% -2.84 to -0.45)(p=0.009). The BMI of the LIP showed a decrease of 0.51kg/m2 (CI 95% -0.29 to 1.33) and the TAU presented an increaseof 0.66kg/m2. Conclusion: The TAU shows a significant increase of body weight while the LIP group had a decrease inbody weight under the Life Intervention program. This study was not intended for patients to reduce body weight, rather toprevent their body weight to increase and enhance their quality of life through understanding physical health, exercise anddietary habit.

Influence of toll-like receptor-4 antagonist on bacterial load of asthma in Swiss albino mice: targeting TLR4/MD2 complex pathway.

Air pollution and environmental issues significantly impact life, resulting in the emergence and exacerbation of allergic asthma and other chronic respiratory infections. The main objective of this study is to suppress allergic asthma by TAK-242 from lipopolysaccharide-induced airway inflammation primarily stimulating toll-like receptor-4, and also to determine the potential mechanism of asthma eradication. The TAK-242 anti-allergic action was assured through the ovalbumin murine model of asthma via bronchial hyperresponsiveness and inflammation of the respiration tract in a pre-existing allergic inflammation paradigm. Swiss albino mice were sensitized and then challenged by ovalbumin and lipopolysaccharide for 5days straight. TAK-242 reaction was assessed by inflammatory cytokines, and inflammatory cell count was determined from blood serum and bronchoalveolar lavage fluid, as well as group-wise regular weight assessments. After ovalbumin, lipopolysaccharide infusion, toll-like receptor-4 agonists caused a substantial increase in airway hyperresponsiveness, specific cellular inflammation, histological alterations, and immune mediator synthesis, as well as dose-related body-weight variations. A decrease in lipopolysaccharide-induced leukocyte count and Th1/Th17 related cytokines, TNF-α, and IL-6 expression through the ELISA study was particularly noticeable. Finally in treated groups, TAK-242, a TLR4/MD2 complex inhibitor, reduced airway inflammation and histopathological changes, cytokine expression, and body-weight management. TAK-242 has been found in an ovalbumin allergic asthma model to be a potential inhibitor of lipopolysaccharide-induced respiratory infection.

Weight changes and the incidence of depressive symptom in the middle-aged and older adults: findings from the Chinese nationwide cohort study

BackgroundPrevious studies, predominantly in Western individuals, have reported weight gain or weight loss are related to the increased depressive symptoms at all ages, but no study of depressive symptoms has examined its relation to actual (not just self-reported) weight changes in the middle-aged and older adults. Evidence of the relationship in older Asian individuals remains sparse. The study aimed to examine the relationship between weight changes and incidence of depressive symptoms in a nationally representative sample of community-dwelling older Asians.MethodData were obtained from the China Health and Retirement Longitudinal Study (CHARLS), which included 17,284 adults aged 45 years. Participants were followed every two years using a face-to-face, computer-aided personal interview (CAPI) and structured questionnaire. We excluded participants with no follow-up data. The numbers of individuals who completed both the baseline and follow-up surveys were 3118 for the short-term (two years from 2011–2013) and the long-term (four years from 2011–2015). Additionally, to associate weight change with subsequent depressive symptoms, we also included 2472 participants without depressive symptom in 2013 and observed the incidence of depressive symptom in 2015 (subsequent term from 2013–2015). Finally, weight changes were classified as loss > -3%, stable-3–3%, gain3-6%, gain6-9%, and gain > 9%. Multivariable-adjusted cox regression in the study were used to assess the hazard ratios (HRs) of each weight change category.ResultsThe incidence of depressive symptoms was 20.72% in the 2011–2013, 27.04% in the 2011–2015, and 23.02% in 2013–2015. Weight loss > 3% for all intervals was associated with higher depressive symptoms than stable weight during the 2011–2013 [1.305(1.031,1.651)] among the total populations. When stratified by sex, the results in males and females were different from those in the total population [females:1.389(0.997, 1.935); males:1.263(0.902, 1.767)]. Weight loss > 3% for intervals was associated with higher depressive symptoms than stable weight during the 2013–2015[1.643(1.140, 2.368)] among the males and its effect was also stronger for the total in 2011–2013. Moreover, there was no significant association between weight gain and incident depressive symptom, and no significant interaction effect in terms of the sex*weight changes.ConclusionOur findings could inform health promotion interventions to body-weight management aimed at improving the health of the middle-aged and older adults, particularly in the total people with short-term weight loss and males with subsequent term weight loss.

Effectiveness of Adherence to a Mediterranean Diet in the Management of Overweight Women: The Prospective Interventional Cohort Study

Evidence indicates that unhealthy eating habits constitute multilevel obstacles threatening health and well-being. Studies suggest that consumer choices have turned irremovably towards Western diets. The Mediterranean diet (MD) is considered one of the most effective in preventing and treating overweight and obesity, yet its results and associations are ambiguous. This explanatory research aims to examine the effect of the MD on anthropometric and biochemical variables in 181 females from an Eastern European country. The sample was divided into three distinct clusters based on age (tricenarian, quadragenarian, and quinquagenarian). Anthropometric and biochemical examinations in the three-month MD program plan failed to provide convincing evidence of the benefits of the MD on selected integrands. However, total body fat (FATP) values between groups showed a significant difference (p ≤ 0.032) between groups A and C (p ≤ 0.029), which can be attributed to the age of the cohort (30-39 vs. 50-60 years). Values in groups A and B (p ≤ 0.001) and C and A (p ≤ 0.001) were significant between the cohorts but did not indicate any changes in visceral fat (VFATL) in the individual groups. The presented findings can have implications for further investigation and the development of more comprehensive instruments, incorporating critical add-on constituents that will be appropriate to monitor, evaluate, and predict body weight management in experimentation.
