Weight Gain In Group Research Articles

Association of pre-pregnancy body mass index to gestational weight gain, diabetes mellitus and hypertension

: The body mass index (BMI) before pregnancy and gestational weight gain (GWG) may have an association with the outcome of pregnancies. Preeclampsia, gestational diabetes, macrosomia show an association with the BMI. A retrospective analysis of the data collected from 720 pregnant mothers during the period from January 2017 to January 2019 in a tertiary health care centre. The chi-square test was done to assess the categorical data.: Gestational hypertension was significant in overweight women and those who gained weight above recommended range. (22.4% Vs. 0%; p <0.001) GDM was noted in a significant percentage of pregnant women within the recommended weight gain group. (12.4% Vs. 0%; p<0.001).: Pre-pregnancy dietary counselling, physical and lifestyle modifications have a role in bringing down the incidence of GDM and gestational hypertension.

Group-Based Trajectory Modeling to Identify Patterns of Antipsychotic-Associated Weight Gain Among Children and Adolescents.

Antipsychotic-associated weight gain (AAWG) is a common adverse effect of second-generation antipsychotic (SGA) medications among children and adolescents. This study applied group-based trajectory modeling to identify latent trajectories of AAWG among children and adolescents and associated risk factors. This was a retrospective analysis of the IQVIA Ambulatory EMR-US database from 2016 to 2021. The cohort consisted of patients aged 6 to 19 years who were SGA naive and received at least 90 days of continuous SGA prescriptions. Group-based trajectory modeling was used to identify latent trajectories of AAWG development during a 24-month period since SGA initiation, and multinomial logistic regression analysis was conducted to examine the risk factors associated with the identified AAWG trajectories. A total of 16,262 patients were included. Group-based trajectory modeling identified the following 4 distinctive AAWG trajectories: persistent severe weight gain (4.2%), persistent moderate weight gain (20.1%), minor weight change (69.6%), and gradual weight loss (6.1%). Compared with the minor weight change group, younger age (12-17 vs 5-11: odds ratio [OR], 0.634; 95% confidence interval [CI], 0.521-0.771), lower baseline body mass index z -score (OR, 0.216; 95% CI, 0.198-0.236), and receiving olanzapine as the initial SGA (olanzapine vs aripiprazole: OR, 1.686; 95% CI, 1.673-1.699) were more likely to follow severe weight gain trajectories. The area under the receiver operating characteristic curves for comparing severe weight gain versus minor weight change groups and moderate weight vs minor weight change groups in the multinomial regression model were 0.91 and 0.8, respectively. A quarter of pediatric SGA recipients experienced persistent weight gain during the SGA treatment. The risk of having persistent AAWG can be predicted using patient characteristics collected before SGA initiation and the initial SGA agent.

Association between Weight Change and Incidence of Dyslipidemia in Young Adults: A Retrospective Cohort Study of Korean Male Soldiers.

Recent lifestyle changes have increased the prevalence of dyslipidemia in Korea. Young men are known to have a low awareness of dyslipidemia and a lack of motivation to maintain their weight. However, the association between weight change and dyslipidemia in young adults has not been thoroughly examined. Data from the Armed Forces Medical Command Defense Medical Information System database were used. In this study, 15,068 soldiers who underwent private and corporal health examinations between May 2020 and April 2022 were included. The difference in weights between the two different health examinations was used to quantify weight change. Four components of the lipid profile were used to assess dyslipidemia during the corporal health examination. After adjusting for relevant covariates, weight gain was associated with increased risk of dyslipidemia (adjusted odds ratio [OR], 1.38 [95% confidence interval, CI, 1.15 to 1.64] for the 5% to 10% weight gain group; and OR, 2.02 [95% CI, 1.59 to 2.55] for the ≥10% weight gain group), whereas weight loss was associated with decreased risk (adjusted OR, 0.82 [95% CI, 0.68 to 0.98] for the 5% to 10% weight loss group; and OR, 0.38 [95% CI, 0.27 to 0.53] for the ≥10% weight loss group). In subgroup analysis based on the participants' baseline body mass index, smoking status, regular exercise habits, and hypertension status, there were no significant differences between the subgroups. Weight change was associated with dyslipidemia in Korean male soldiers. The findings suggest that limiting weight gain in young adults by encouraging a healthy lifestyle may help prevent dyslipidemia.

The role of lifestyle and mental health in the weight change of higher vocational college students in Fuzhou, China during COVID-19

ObjectivesThis study is aimed to explore the influence of higher vocational college students' lifestyle and mental health on weight change in Fuzhou during COVID-19. MethodsThis study adopted the cross-sectional study method and a total of 1426 students (1111 women and 315 men) were recruited from higher vocational college in Fuzhou. The questionnaire mainly included six dimensions: demographic characteristics, anthropometric measurements, dietary habits, physical activity, sleep quality and psychological status. ResultsAccording to the weight changes, the group was divided into weight loss group, constant weight group and weight gain group. More people in the weight gain group had increased their intake of various foods compared to the other groups (P < 0.001), in addition,the number of physical activity decreased and basically unchanged was more, and the number of sedentary time increased and basically unchanged was more in the three groups(P < 0.001). The incidence of poor sleep quality (60.3 %, 46.9 %, 57.5 %, P < 0.001), depressive symptoms (58.9 %, 47.5 %, 62.0 %, P < 0.001) and anxiety symptoms (42.5 %, 35.8 %, 45.3 %, P = 0.005) in the weight loss group and the weight gain group were significantly higher than those in the constant weight group. After adjusting for the potential confounders (including age, sex, grade, smoking, drinking, diet, etc.), decreased physical activity, depressive symptoms and anxiety symptoms were independent risk factors for weight gain compared with the constant weight group(OR = 1.643, P = 0.046; OR = 1.695, P < 0.001; OR = 1.389, P = 0.020). ConclusionsThe increased food intake, decreased physical activity, depressive symptoms and anxiety symptoms were positively correlated with weight gain.

Association between weight gain following smoking cessation and development of hypertension in the future.

Although quitting smoking lowers the risk of developing chronic conditions, it usually leads to weight gain. Literature on the association between weight gain after quitting smoking and the future development of hypertension is scarce. Among 234 596 individuals who visited our health center, 856 who had quit smoking for whom data were available at least 6 years after smoking cessation were included. We evaluated changes in blood pressure and antihypertensive drug prescription rate at 1 and 6 years after smoking cessation. We also compared weight and blood pressure between the smoking cessation and continued smoking groups after 6 years. Multiple regression analyses were performed to identify predictors of changes in systolic and diastolic blood pressures using covariates affecting blood pressure. Since a median weight gain of 1.8 kg was observed at 1 year after smoking cessation, we divided the participants into high and low-weight gain groups. No significant intergroup difference in the antihypertensive drug prescription rate was observed after 6 years. The high weight gain group showed significant increases in systolic and diastolic blood pressures after 6 years. Multiple regression analyses revealed that systolic blood pressure was affected by age and high weight gain, while diastolic blood pressure was affected by high weight gain. Our findings suggest that weight gain following smoking cessation leads to blood pressure elevation: the smoking cessation group gained more weight and had higher blood pressure than the continued smoking group. Therefore, weight loss guidance may be useful for individuals who want to quit smoking. Participants in the high weight gain group showed significant increases in systolic and diastolic blood pressures at 6 years after smoking cessation that were significantly different from those observed in participants in the low weight gain group and the continued smoking group.

Weight loss enhances meniscal healing following transtibial pullout repair for medial meniscus posterior root tears.

This study investigated the impact of weight change on the success of transtibial pullout repair for medial meniscus (MM) posterior root tears (MMPRTs). The study included 129 patients diagnosed with MMPRTs who had undergone transtibial pullout repair. The patients were screened between July 2018 and November 2021. Patient-reported outcomes were assessed preoperatively and at 12 months postoperatively using the Knee injury and Osteoarthritis Outcome Score (KOOS). MM extrusion (MME) and ΔMME (postoperative MME - preoperative MME) were calculated preoperatively and at 12 months postoperatively using magnetic resonance imaging. Patients were divided into weight loss (body mass index [BMI] decrease of at least 0.5 kg/m2 after primary repair; n = 63) and weight gain (BMI increase of at least 0.5 kg/m2 ; n = 66) groups. Both groups had similar demographic variables and preoperative clinical scores; patient-reported outcomes significantly improved postoperatively. The weight loss group had significantly greater improvement in KOOS-quality of life (weight loss, 29.4 ± 23.7; weight gain, 23.9 ± 27.6; p = 0.034), lower postoperative MME (weight loss, 3.9 ± 1.7 mm; weight gain, 4.2 ± 1.2 mm; p = 0.043) and lower ΔMME (weight loss, 0.8 ± 0.8 mm; weight gain, 1.2 ± 0.9 mm; p = 0.002) than the weight gain group. Total arthroscopic healing scores (weight loss, 7.6 ± 1.0; weight gain, 7.2 ± 1.5; p = 0.048) and associated subscales, including anteroposterior bridging tissue width (weight loss, 4.0 ± 0.0; weight gain, 3.8 ± 0.7; p = 0.004) and MM posterior root stability (weight loss, 2.6 ± 0.7; weight gain, 2.4 ± 0.7; p = 0.041), significantly differed between the groups. Weight loss was associated with better meniscal healing and less MME progression after MMPRT repair, highlighting the significance of weight management in individuals undergoing meniscal surgery. These findings provide valuable insights into the clinical significance of weight loss in the success of transtibial pullout repair for MMPRTs. Level III.

Integrative network analysis of differentially methylated regions to study the impact of gestational weight gain on maternal metabolism and fetal-neonatal growth.

Integrative network analysis (INA) is important for identifying gene modules or epigenetically regulated molecular pathways in diseases. This study evaluated the effect of excessive gestational weight gain (EGWG) on INA of differentially methylated regions, maternal metabolism and offspring growth. Brazilian women from "The Araraquara Cohort Study" with adequate pre-pregnancy body mass index were divided into EGWG (n=30) versus adequate gestational weight gain (AGWG, n=45) groups. The methylome analysis was performed on maternal blood using the Illumina MethylationEPIC BeadChip. Fetal-neonatal growth was assessed by ultrasound and anthropometry, respectively. Maternal lipid and glycemic profiles were investigated. Maternal triglycerides-TG (p=0.030) and total cholesterol (p=0.014); fetus occipito-frontal diameter (p=0.005); neonate head circumference-HC (p=0.016) and thoracic perimeter (p=0.020) were greater in the EGWG compared to the AGWG group. Multiple linear regression analysis showed that maternal DNA methylation was associated with maternal TG and fasting insulin, fetal abdominal circumference, and fetal and neonate HC. The DMRs studied were enriched in 142 biological processes, 21 molecular functions,and 17 cellular components with terms directed for the fatty acids metabolism. Three DMGMs were identified:COL3A1, ITGA4 and KLRK1. INA targeted chronic diseases and maternal metabolism contributing to an epigenetic understanding of the involvement of GWG in maternal metabolism and fetal-neonatal growth.

Changes in Biochemical Components of Obesity in Wistar Rats Fed Mentha Piperita-Supplemented High-Fat Diet

The research is designed to assess changes in biochemical components of obesity in Wistar rats fed peppermint-supplemented high-fat diet. Twenty (20) female Wistar rats of about 117.88±10.82g were divided into four (4) groups of five (5) rats each and randomly assigned to the formulated diets. The groups had similar average weights. Groups A and B were fed standard diet and High-fat diet respectively, while groups C and D were respectively fed 4% peppermint-supplemented standard diet and 4% peppermint-supplemented high-fat diet. The changes in weight and blood glucose level were monitored on weekly basis. At the end of six (6) weeks of the experiment, organ to body weight ratio, serum insulin level and HOMA-IR were determined. Markers of hepatic functions (transaminases, total bilirubin, albumin, globulin, conjugated bilirubin and total protein), markers of renal functions (electrolyte concentrations, urea and creatinine), serum activities of antioxidant enzymes (catalase, glutathione peroxidase, reduced glutathione and superoxide dismutase) and serum concentrations of malondialdehyde (MDA) were also determined. No significant (p≤0.05) differences were observed among the groups in weight gain, organ to body weight ratio, blood glucose levels, activities of antioxidant enzymes and serum MDA concentrations. The group fed 4% peppermint-supplemented high-fat diet had significantly (p≤0.05) higher activities of ALT, AST, total cholesterol and low-density lipoprotein cholesterol but significantly (p≤0.05) lower high-density lipoprotein cholesterol when compared with the group fed standard diet or high-fat diet. Serum creatinine and bicarbonate were significantly (p≤0.05) lower in the group fed 4% peppermint-supplemented high-fat diet compared with the group fed the standard diet. It is therefore concluded that including peppermint leaf powder in the diet for a period of 6 weeks may not have a significant impact on the body weight, organ development and glucose utilisation. However, it is important to note that consumption of high-fat diet supplemented with peppermint might lead to dyslipidemia, liver and kidney dysfunctions without altering oxidative balance in Wistar rats.

Cardiovascular effects of weight loss in old adults with overweight/obesity according to change in skeletal muscle mass.

Patients with overweight/obesity and type 2 diabetes are encouraged to lose weight, but not all losing weight gain better cardiovascular health, especially old adults. The change in skeletal muscle mass (SMM) could be the key that explains the heterogenous cardiovascular effects of weight loss. This study aims to assess whether the cardiovascular effects of weight loss vary for those gaining skeletal muscle along with weight loss. The old adults with overweight/obesity and type 2 diabetes in the Look AHEAD study having muscle measurement from dual-energy X-ray absorptiometry were included. Based on the weight change (WC) and SMM change (SMMC) between baseline and the 4-year follow-up, participants were allocated into three groups-weight gain (WG) group, weight loss with muscle loss (WL-ML) group and weight loss with muscle gain (WL-MG) group. Cox proportional hazards regression was performed to evaluate the cardiovascular risk of those gaining or losing SMM with weight loss compared with those gaining weight. Among the participants with weight loss, the ratio of SMMC/WC was calculated, and the association of SMMC/WC with primary cardiovascular outcome was assessed. A total of 491 participants were included in the study with an average age of 64.56±3.81years old. A total of 47.0% were male and 49.9% were from the intensive lifestyle intervention arm. Based on their WC and SMMC, 43 were assigned to the WG group, 373 to the WL-ML group and 75 to the WL-MG group. Over a follow-up of almost 10years, 97 participants encountered the primary endpoint. The WG group had the highest incidence of 25.59%, the WL-MG group had the lowest incidence of 9.33% and the WL-ML group had 21.18% (P=0.040). In the fourth adjusted Cox model, the WL-MG group achieved significantly decreased odds of the primary endpoint compared with the WG group (hazard ratio [HR] 0.33, 95% confidence interval [CI] [0.12, 0.87], P=0.026), whilst the WL-ML group did not (HR 0.91, 95% CI [0.47, 1.78], P=0.670). Among the participants with weight loss, when SMMC/WC reached around 50%, this HR soared to approximately two-fold. The participants gaining SMM along with weight loss achieved the lowest odds of adverse cardiovascular events, whilst those who lost SMM along with weight loss had comparable cardiovascular risk with those gaining weight. The more muscle lost during weight loss, the greater the harm. The cardiovascular effects of weight loss were modulated by whether the participants gained SMM meanwhile losing weight.

Severity of excessive gestational weight gain and risk of severe maternal morbidity

Both obesity and excessive gestational weight gain are associated with severe maternal morbidity, but there is limited literature evaluating whether the risk of severe maternal morbidity is further increased by the degree or severity of excessive gestational weight gain. This study aimed to determine whether pregnant patients with excessive gestational weight gain who gained more than 50 lb were at increased risk of severe maternal morbidity compared with those who only moderately exceeded recommended gestational weight gain guidelines. A secondary objective was to determine whether patients who gained 10 lb more than the recommended upper limit of total weight gain for a given prepregnancy body mass index group were at increased risk of severe maternal morbidity compared with those who exceeded that upper limit by a lesser amount. This was a retrospective cohort study of all patients with live, term, singleton deliveries with excessive gestational weight gain from 7 hospitals within a large health system in New York between January 2019 and February 2020. Excessive gestational weight gain was defined as exceeding the recommended upper limit of total weight gain for a given prepregnancy body mass index category using the National Academy of Medicine gestational weight gain guidelines: >40 lb for a body mass index of <18.5 kg/m2, >35 lb for a body mass index of 18.5 to 24.9 kg/m2, >25 lb for a body mass index of 25.0 to 29.9 kg/m2, and >20 lb for a body mass index of ³30.0 kg/m2. Patient height and weight data were self-reported at the time of delivery hospitalization and retrieved from the electronic medical record system. Patients were classified into 2 excessive gestational weight gain groups: moderate (≤50 lb) or severe (>50 lb). Patients with missing body mass index or gestational weight gain were excluded. The primary exposure was severe excessive gestational weight gain. The primary outcome was severe maternal morbidity, defined using the Centers for Disease Control and Prevention criteria. Logistic regression was used to model the likelihood of severe maternal morbidity, adjusting for race and ethnicity, nulliparity, advanced maternal age, gestational diabetes mellitus, and maternal mood disorder. For the secondary analysis, severe maternal morbidity rates were compared between patients who exceeded their body mass index-specific upper limit of total weight gain by ≥10 lb and those who exceeded it by <10 lb. A total of 11,506 patients were included for analysis, and 1965 patients (17.1%) had severe excessive gestational weight gain. The overall rate of severe maternal morbidity was 3.3%. Severe maternal morbidity occurred in 85 of 1965 patients (4.3%) with severe excessive gestational weight gain and 292 of 9541 patients (3.1%) with moderate excessive gestational weight gain. On regression analysis, after adjustment for covariate factors, patients with a severe excessive gestational weight gain were 39% more likely to experience severe maternal morbidity than those with moderate excessive gestational weight gain (adjusted odds ratio, 1.39; 95% confidence interval, 1.08-1.79). Patients with excessive gestational weight gain of ≥10 lb above the recommended body mass index-specific upper limit for gestational weight gain were 32% more likely (adjusted odds ratio, 1.32; 95% confidence interval, 1.07-1.62) to experience severe maternal morbidity than patients who exceeded that upper limit by <10 lb. Patients with live, term, singleton pregnancies who gain more than 50 lb are at increased risk of severe maternal morbidity compared with those who only moderately exceed gestational weight gain guidelines. Similarly, patients who gain ≥10 lb above the recommended body mass index-specific upper limit for gestational weight gain are at increased risk. Further study is warranted to determine the most effective interventions to manage gestational weight gain and mitigate maternal risk.

Causes of possible excessive weight gain in exclusively breastfed infants in the first six months of life.

The aim of this study was to describe factors related to the infant, mother, and breastmilk composition that may be associated with excessive weight gain in a cohort of exclusively breastfed infants younger than 6 months of life with excessive weight gain, and to compare these findings with data from a group of normal-weight exclusively breastfed infants. Thirty-six exclusively breastfed infants younger than 6 months of life seen at two health-care centers between July 2016 and 2017 were enrolled in the study. The clinical features of the infants, their mothers, and the macronutrient composition of the breast milk were evaluated. We classified infants according to weight gain velocity between birth and 6 months of life into an excessive weight gain (EWG) and an adequate weight gain (AWG) group. Mean age at protocol entry was 3.8 months. Thirteen patients were classified as EWG and 23 patients as AWG. Co-sleeping was more often observed in EWG than in AWG infants. Mothers in the EWG group were younger and more often had gained more than 18 kg during pregnancy than those in the AWG group. No significant differences were found in the macronutrient content of the breast milk between both groups. Greater weight gain in infants under 6 months of age may be related to greater weight gain of the mother during pregnancy, younger age of the mother, and co-sleeping of the mother and child.

Characterizing alterations in the gut microbiota following postpartum weight change.

Previous research has reported differences in the gut microbiome associated with varying body compositions. More specifically, within populations of mothers, the focus has been on the impact of gestational weight gain. This is the first study to examine postpartum weight change and its association with changes in the gut microbiome, similarly, it is the first to use a Latina cohort to do so. The results support the idea that weight gain may be an important factor in reducing gut microbiome network connectivity, diversity, and changing abundances of specific microbial taxa, all measures thought to impact host health. These results suggest that weight gain dynamically alters mothers' gut microbial communities in the first 6 months postpartum, with comparatively little change in mothers who lost weight; further research is needed to examine the health consequences of such changes.

Association between Lifestyle Factors and Weight Gain among University Students in Japan during COVID-19 Mild Lockdown: A Quantitative Study.

We aimed to investigate the lifestyle factors influencing weight gain among university students in Japan during the mild lockdown imposed due to the novel coronavirus disease pandemic. In this cross-sectional study, we conducted a questionnaire survey of students who underwent health examinations at Nagasaki University in 2021. Students reporting a weight gain of ≥3 kg were included in the weight gain group; the remaining students were included in the non-weight-gain group. Fisher's exact test and binary logistic regression were performed to determine the association between weight gain and each lifestyle factor. We included 3059 respondents (response rate: 45.7%), and 9.5% of them reported a weight gain of ≥3 kg. The following factors were associated with weight gain (odds ratio (95% confidence interval), p value based on Fisher's exact test): dining out for four times or more/week (2.16 (1.40, 3.32), p = 8.7 × 10-4) and gaming time of ≥4 h/day (2.26 (1.45, 3.47), p = 2.4 × 10-4). Binary logistic regression among the four highest odds ratios revealed that after adjusting for other factors, frequent dining out and prolonged gaming time were significantly associated with weight gain in students during the mild lockdown.

Comparison of Effect of Feeding Premature Infants with Either Cup, Bottle, and Syringe on Transition to Breastfeeding, Breastfeeding Success, Weight Gain, and Duration of Hospitalization.

Objective: This study was completed with the aim of determining the effect of cup feeding (CF), bottle feeding (BF), and syringe feeding (SF) methods on the transition to breastfeeding, breastfeeding success, physiological parameters, weight gain, and discharge duration for preterm neonates in the neonatal intensive care unit (NICU). Materials and Methods: The study was designed to be randomized, controlled, and single blinded. The study was completed with 102 premature neonates between 29-34 gestational weeks abiding by the case selection criteria receiving treatment and care in the NICU. The 1st group comprised premature neonates receiving CF, the second group received BF, and the third group received SF. For collection of data, the Premature Infant Descriptive Information and Monitoring Form, Bristol Breastfeeding Assessment Tool (BBAT), and Infant-Focused Feeding Scales (IFFS) were used. Results: Comparison of mean peak heart rate in the groups found that the BF group was significantly high (p = 0.047) and comparison of mean SO2 found that the SF group was significantly high (p = 0.000). Infants in the SF group were determined to have significantly higher BBAT scores compared to the infants in the BF and CF groups (p = 0.015). In addition, SF infants were determined to transition to full enteral feeding and breastfeeding in a shorter duration (p < 0.05). There were no significant differences between the groups for weight gain and discharge duration (p > 0.05). Conclusions: The SF method was determined to more positively affect breastfeeding success, transition to full breastfeeding duration, and vital signs compared to the CF and BF methods. In line with the results obtained in the study, the use of the SF method may be recommended to increase breastfeeding success of neonates, to shorten the transition to full breastfeeding and for stable physical parameters.

Weight Loss Is a Strong Predictor of Memory Disorder Independent of Genetic Influences.

Past studies identified a link between weight loss and dementia, but lacked consistent conclusions. We sought to establish this link by examining the weight change profiles before and after dementia diagnosis. Using data from the Health and Retirement Study (1996-2020), we examined 13,123 participants. We conducted a nested case-control analysis to assess differences in biennial weight change profile while controlling for BMI, longevity polygenic risk scores, and APOE gene variants. Participants with a memory disorder lost weight (-0.63%) biennially, whereas those without a diagnosis did not (+0.013%, p-value < 0.0001). Our case-control study shows a significant difference (p-value < 0.01) in pre-dementia % weight changes between the cases (-0.29%) and controls (0.19%), but not in post-dementia weight changes. The weight loss group have the highest risk (OR = 2.01; p-value < 0.0001) of developing a memory disorder compared to the stable weight and weight gain groups. The observations hold true after adjusting for BMI, longevity polygenic risk scores, and APOE variant in a multivariable model. We observe that weight loss in dementia is a physiological process independent of genetic factors associated with BMI and longevity. Pre-dementia weight loss may be an important prognostic criterion to assess a person's risk of developing a memory disorder.

Effectiveness of a preoperative orlistat-based weight management plan and its impact on the results of one-anastomosis gastric bypass: A retrospective study.

The aim was to first investigate the efficacy of a preoperative weight management program centered on orlistat, which is mechanistically similar to gastrointestinal bypass procedures in that it restricts dietary fat absorption, and then assess its impact on the results of one-anastomosis gastric bypass (OAGB). We retrospectively reviewed the clinical data of consecutive patients aged 20-65 years with a body mass index (BMI) ≥ 42.5 kg/m2 who underwent primary OAGB from 2014 to 2020. Eligible patients who adhered to a 10-14 day orlistat regimen as part of a 4-6-week diet/lifestyle modification plan preceding surgery were stratified into weight reduction (Group 1) and weight gain (Group 2) groups post treatment. The correlation between pre- and postoperative weight loss and perioperative outcomes was assessed. Of 62 eligible patients, 55 met the inclusion criteria and complied with treatment; 35 (64%) patients in Group 1 lost a median of 2.0 kg, and Group 2 had a median weight gain of 2.9 kg. Group 1 had a significantly higher initial BMI (48.9 kg/m2 vs. 44.6 kg/m2; p = 0.003), more females (54% vs. 25%) and a shorter operation time than Group 2 (107 min vs. 140 min; p = 0.109). There was no difference in the incidence of 30-day complications. Weight loss did not differ between the groups at 24 months. Effective weight control through an orlistat-containing regimen benefitted two-thirds of patients who underwent OAGB; however, further weight loss was not observed at 2 years post-surgery.

Effects of Dietary Fish Meal Replacement with Alternative Protein Ingredients and Their Combinations on Growth Performance, Feed Utilization, Fillet Composition, and Biochemical Parameters of Red Seabream (Pagrus major).

The experiment was conducted to evaluate alternative protein ingredients in a low-fish meal (FM) diet for red seabream (Pagrus major). Twelve experimental diets were formulated. Control diet (CON) was designed to contain 60% FM. Other experimental diets were formulated by replacing 50% of FM from the CON with soy protein concentrate (SPC), corn gluten (CG), meat meal (MM), and/or chicken byproduct meal (CBM). Four diets were designed including one of SPC, CG, MM, or CBM as FM replacer and designated as SPC, CG, MM, and CBM. Six other diets were formulated by adding two ingredients as SPC and CG, SPC and MM, SPC and CBM, CG and MM, CG and CBM, or MM and CBM, and designated as SCG, SMM, SCM, CMM, CCM, and MCM, respectively. The 12th diet (MIX) was formulated by including SPC, CGM, MM, and CBM. Triplicate fish groups (50.2 ± 0.1 g) were hand-fed for 12 weeks. Weight gain (WG) of fish was significantly improved by MM and MCM diets compared to CG, SCG, CMM, and CCM diets. WG of CON, SPC, CM, SMM, SCM, and MIX groups were comparable with MM and MCM groups. The lowest WG was observed in CG and CMM groups. Feed efficiency (FE) was significantly higher in MM group compared to SPC, CG, SGC, and CMC groups. FE of MCM group was significantly higher than CG and SCG groups. Fillet linolenic acid (C18:2n-6) level in CG group was significantly higher than CON, MM, CM, SCM, CCM, and MCM groups. Serum lysozyme activity was significantly higher in MCM and MIX groups. Therefore, a high level of dietary CG reduces the growth performance and feed utilization of red seabream. A mixture of MM and CBM seems to be more efficient in replacing FM from red seabream diet.

Body mass index variation in adults with Williams syndrome: associations with predicted dietary intake and food behaviors.

Dietary intake and body weight are important predictors of long-term health. However, few studies have focused on these topics in adults with genetic syndromes that have associated intellectual disability, such as Williams syndrome (WS). In adults with WS, describe predicted dietary intake, food-related problems, and associations between body mass index (BMI) and possible factors contributing to differences in weight status. In this study of 82 participants (median age of 30 years, range 18-69), we cross sectionally investigated associations between BMI, predicted dietary intakes (Dietary Screener Questionnaire), food-related behaviors (Food-Related Problem Questionnaire), and anxiety (Spence Children's Anxiety Scale). Longitudinal patterns of weight change were further studied in a subset (n = 41). BMI variation was observed with median BMI of 27.3 kg/m2 (range 16.7-55.5 kg/m2). Several components of dietary intake deviated from recommendations in the WS cohort. When compared with WS participants with either normal or overweight BMI, WS participants with obesity had reduced daily intake of fruits and vegetables of 0.15 cup equivalents (P = 0.049), while participants with underweight BMI had reduced daily intake of fruits and vegetables of 0.44 cup equivalents (P = 0.026) and additionally had reduced intake of dietary fiber of 2.12 grams per day (P = 0.019). A one-point increase in the 'preoccupation with food' sub-score was associated with a 0.57 unit increase in BMI (P = 0.16), while a one-point increase in the 'takes and stores food' sub-score was associated with a 0.72 unit increase in BMI. In the longitudinal weight subset, a weight gain group and a weight stable group were identified. The former was associated with increased 'takes and stores food' sub-score but not with dietary intakes. We observed considerable BMI variability. While few dietary intakes were associated with BMI, increased BMI and weight gain were associated with 'preoccupation with food' and with 'takes and stores food' behavior sub-scores.

Maternal and perinatal outcomes in women conceiving after bariatric surgery: A cohort study.

Obesity in women, a global issue, is being widely managed with bariatric surgery worldwide. According to recommended guidelines, pregnancy should be avoided for 12 to 24 months following surgery due to various risks. We assessed if surgery-to-conception time has a relation with pregnancy outcomes taking into account gestational weight gain. A cohort study between 2015 and 2019 followed-up pregnancies after various types of bariatric surgeries performed (e.g. Roux-en-Y gastric bypass, sleeve gastrectomy, gastric banding, gastric bypass with Roux-en-Y gastroenterostomy) in Tawam Hospital, Al Ain, United Arab Emirates. There were 5 surgery-to-conception groups: <6 months, 6 to 12 months, 13 to 18 months, 19 to 24 months, and >24 months. There were 3 gestational weight gain groups: inadequate, adequate, or excessive (based on the National Academy of Medicine classification). Maternal and neonatal outcomes were compared using analysis of variance and chi-square tests. There were 158 pregnancies. Booking maternal body mass index and weight were higher among mothers who conceived <6 months following surgery (P < .001). Gestational weight gain was not related to the type of bariatric surgery (P = .24), but it was far more often inadequate in mothers who conceived <12 months following surgery (P = .002). Maternal (including pregnancy-induced hypertension and gestational diabetes mellitus) and neonatal outcomes were not statistically significantly associated with surgery-to-conception duration. However, birth weight was lower when gestational weight gain was inadequate (P = .03). There is a negative relationship between shorter bariatric surgery-to-conception interval and gestational weight gain, a feature related to neonatal birth weight. Conception should be delayed to improve pregnancy outcomes following bariatric surgery.

Effect of ad libitum feeding of Holstein Friesian calves on immunological parameters and molecular stress on a transcriptional level

Our aim was to compare the health and performance of ad libitum (ADLIB) and restrictedly fed Holstein Friesian heifer calves. Calves were selected to ADLIB (n = 13) and control (n = 13) groups randomly. The period of ADLIB feeding lasted for 3 weeks after colostrum supplementation. The calves in the control group received the same milk replacer, which was supplied according to the restrained feeding schedule of the farm. There was no difference between the two groups in weight, weight gain or movement activity, furthermore in the values of glucose, albumin, total protein, BHB, AST, oxidant and antioxidant status incl. dROM, PAT and OSI. The IL8 gene had higher levels (non significant, p > 0.05) of expression in the ADLIB group during the first 20 days of life, which indicates that ADLIB feeding might potentiate a stronger immune response to environmental stress. The IGF1 gene showed increased expression in the ADLIB fed group at almost all time points, however the difference was already detected on the first day of the study, indicating the importance of individual differences even within the same breed. During the first 10 days INS expression was higher in the restricted group, followed by a shift by day 20 and after, when the ADLIB group showed a higher relative expression level. The observed values describe a trend that, although not significant (p > 0.05), would seem to indicate that ADLIB feeding might potentiate a stronger immune response to environmental stress.
