Background and Objective: Nutrition is a basic need for athletes; thus, adequate dietary intake is crucial for maintaining overall health, facilitating training adaptations and boosting athletic performance. Accurate dietary assessment tools are required to minimize the challenges faced by athletes. This study verifies the validity and reproducibility of a 157 item semi-quantitative food frequency questionnaire (FFQ) among Lebanese athletes. This is the only Arabic questionnaire in Lebanon that estimates food consumption for athletes which can also be used in Arabic speaking countries. There has been no previous validated food frequency questionnaire that estimated food consumption for athletes in Lebanon., Methods: A total of 194 athletes were included in the study to assess the validity of the food frequency questionnaire against four days dietary recalls by comparing the total nutrient intake values from the food frequency questionnaire with the mean values of four 24-hour dietary recalls using Spearman correlation coefficient and Bland Altman plots. In order to measure the reproducibility, the intra class correlation coefficients were calculated by repeating the same food frequency questionnaire after one month., Results: The intra-class correlation coefficient between the two-food frequency questionnaires ranged from average (0.739 for carbohydrates) to good (0.870 for energy (Kcal)), to excellent (0.919 for proteins) concerning macronutrients and ranged from average (0.688 for vitamin D), to excellent (0.952 for vitamin B12), indicating an acceptable reproducibility. Spearman's correlation coefficients of dietary intake estimate from the food frequency questionnaire and the four dietary recalls varied between 0.304 for sodium, 0.469 for magnesium to 0.953 for caloric intake (kcal). Bland-Altman plots illustrated a percentage of agreement ranging between 94.3% for fats to 96.4% for proteins., Conclusion: This food frequency questionnaire has a reliable validity and reproducibility to evaluate dietary assessments and is an appropriate tool for future interventions to ensure the adoption of adequate eating strategies by athletes., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Sannan et al.

The objective of this study was to evaluate the intake and digestibility of nutrients, production and composition of milk, and water intake of lactating dairy cows fed standard diets in which ground corn (C) was replaced by up to 100% in the diet by cactus pear (CP). Eight Girolando cows (½ Gyr x ½ Holstein), 3rd calf multiparous, with 60 to 80 days of lactation and an average weight of 450.0 ± 30.0 kg, were randomly distributed in a double Latin square (4 × 4). Four experimental diets were evaluated: (100% C + 0% CP), (66.6% C + 33.3% CP), (33.3% C + 66.6% CP), and (0% C + 100% CP). There was a difference (P < 0.05) in the intake of CP and EE (kg.day - 1 ), with a quadratic effect and a linear reduction, respectively, with substitution. The maximum CP intake of 3.05 kg.day - 1 was found at 46.07% and EE intake fell by 3.81 g for each percentage unit of cactus pear added to the diet. There was a quadratic difference (P < 0.05) for DM intake in %BW and g.kg BW 0,75 , with maximum values of 3.97%BW and 186.8 g.kg BW 0,75 with the substitution of 54.83 and 53.17%, respectively. There was a quadratic effect (P < 0.05) for the intake of NDF in %BW, with the maximum intake of 1.3% at the 74.69% substitution level. There was a linear reduction (P < 0.05) in the digestibility of DM, NDF, and TDN, and for the other nutrients there was no substitution effect (P > 0.05). There was no difference (P > 0.05) in milk production and composition. There was a linear reduction (P < 0.05) in water intake. Cactus pear can be used in a promising way to replace ground corn up to 100% in the diet of lactating dairy cows., (© 2024. The Author(s), under exclusive licence to Springer Nature B.V.)

Background : Many studies have reported on the relationship between cognitive and masticatory functions. However, it remains unclear how the mandibular movements change during chewing in facility residents as dementia progresses. This study aimed to investigate the relationship between a kinematic analysis of mandibular movement during mastication and cognitive function in facility residents. Methods: Sixty-three participants were included from two long-term care facilities. The primary outcome variable was the kinematic data of mandibular movement during mastication. The participants chewed rice crackers, and their faces were recorded during this motion. The partial correlation coefficient between kinematic data and cognitive function was calculated. Furthermore, group comparisons were performed after dividing the participants into three groups based on their cognitive function. Results: Circular motion frequency was significantly correlated with the ABC dementia scale, even after adjusting for the appendicular skeletal muscle index, Eichner index, and short-form mini-nutritional assessment. The cycle and circular motion frequencies were markedly lower in the severe dementia group than in the mild dementia group. Conclusions: With declining cognitive function, mandibular movements during mastication decrease in circular motion and increase in linear motion. Additionally, our results suggested that residents with severe cognitive impairment had more linear mandibular motions during mastication than those with mild cognitive impairment. This may make it more difficult for residents with cognitive decline to ingest normal solid foods.

Taste and smell are of direct importance in most social interactions. Radical disruptions in these senses can, therefore, substantially disrupt sociality. This paper focuses on the experiences of a particular type of disruption: persistent chemosensory dysfunctions after COVID-19. We conducted semi-structured interviews with 30 patients undergoing treatment for chemosensory dysfunctions and analyzed the ways in which their experiences have influenced social relations and activities, particularly regarding food and eating. The findings reveal that these dysfunctions have made the participants markedly aware that food and eating are pivotal to full participation in social life. As is smell, both surrounding smells and the perception of one's own smell, with dysfunctions leading to several social consequences. Such problems are handled through both avoidance behavior and adaptations. While adaptations facilitate interactions, they come at the cost of feeling a burden to others or not fully appreciating an event (e.g., a shared meal). Social support is of great importance, ranging from minor practical assistance, such as a friend checking if the milk is sour, to the profound emotional relief felt from empathic treatment and recognition that the problems are real. Here, healthcare professionals can play a vital role, even in the (perceived) absence of clinical effectiveness of the treatment. The experiences expressed are partially in line with other manifestations of Long COVID and with chemosensory dysfunctions due to other illnesses, but only partially, since this is a patient group with needs and experiences that are unique, in that sociality is so strongly affected solely by disruptions in sensory abilities., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Antarctica has traditionally been viewed as a relatively isolated ecosystem. Although still considered pristine, it is increasingly also being affected by microplastic pollution. Reported high sea floor concentrations raise concern that these ecosystems might act as major sink for microplastic pollution. This is significant as species in those remote ecosystems are likely more sensitive to rapid environmental change due to a high level of specialization, and lower tolerance levels. Microplastic ingestion in fish has barely been assessed in high latitude environments. Here we aimed to provide baseline data for the eastern Weddell Sea, which is particularly remote, and suggested for an area of conservation. By analyzing gastrointestinal tracts of 40 specimens from five species, we report an overall microplastic incidence rate of 0.23. This is lower than recent studies have found for other species in the Southern Ocean, and below global means. The highest incidence rate was detected in L. squamifrons (0.67), followed by P. evansii (0.29). The most common polymer was polyethylene recovered as 8 particles (42.1 %) from one specimen, while from the remaining 11 microplastics polyester was most common (36.8 %). This study shows that even in a remote region of the Antarctic Ocean with almost no vessel traffic, fisheries or touristic activity, bathydemersal and bathypelagic fish exhibit microplastic particles in their gastrointestinal tract., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Objective: Peers can significantly influence eating behaviours in school-aged children and adolescents. Studies vary in methodology and terminology and report inconsistent age and sex differences. No review has collated evidence within early childhood. This review aims to explore what is currently known about peer influence and eating behaviours in young children and identify knowledge gaps regarding commonly assessed eating behaviours, peer definitions, peer influence assessment methods, and theoretical frameworks., Methods: A search of electronic databases (Embase, ERIC, Medline, APA PsycInfo, Scopus) was conducted. The review included peer-reviewed, primary research that explored peer influence on eating behaviour in any group context, published between 1980 and 2023, available in English full-text. Participants were aged between two and seven years. Primary and secondary screening were conducted by two authors. Data extraction was conducted by one author with a second author duplicating 25%., Results: Twenty-six of the 3961 unique identified studies met inclusion criteria. Most studies (76%) report peers to influence eating behaviours. Peer influence was a primary aim in 18 studies, of which 17 were experimental, and peer influence emerged as a finding in seven studies. All phenomena of interest varied widely. Eating behaviour concept definitions were inconsistent, with four studies assessing hypothetical eating behaviours. Peers varied by age, familiarity, and in-person versus remote exposures. Six theoretical frameworks were referenced, and eleven studies lacked theoretical underpinning. No studies measured peer influence directly or obtained children's perspectives., Conclusions: Peers may influence eating behaviours within early childhood. Peer familiarity and age potentially impact peer influence magnitude. Variations in study design and peer definitions make comparisons challenging. Future research should utilise observational designs to explore peer influence on child eating behaviours within naturalistic settings., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Sarah Street reports financial support was provided by Queensland University of Technology.

Microplastics (MPs) are widely distributed in marine environments and ingested by marine organisms, especially zooplankton. Chaetognaths, typical carnivorous zooplankton, are pivotal in the food chain from secondary producers, such as copepods, to higher trophic level species. However, little is known about their MP ingestion. In this study, based on field observation data, for the first time, we studied seasonal characteristics and risks of MPs ingested by chaetognaths in Jiaozhou Bay and assessed effects of key prey copepods on MP ingestion by chaetognaths. MP/chaetognath values in February, May, August, and November were 0.19, 0.17, 0.15, and 0.39, respectively, showing no significant seasonal variation. Chaetognaths predominantly ingested MPs that were fiberous in shape, 101-400 µm in size and polyester in polymer type, with no significant seasonal variations. The risk of MP load in chaetognaths was low, but there are higher polymeric hazards and potential ecological risks. MP/chaetognath values were positively correlated with the copepod abundance and MP/copepod values. The characteristics of MPs ingested by chaetognaths were also highly similar to those of MPs ingested by copepods. However, the overall risk of biomagnification in the copepod-chaetognath food chain was low. This study provided field evidence for MP transfer in the planktonic food chain., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Background: Mobile apps represent accessible and cost-effective tools to improve nutrition and prevent chronic diseases. However, most of these apps have been characterized as having limited functionality, raising concerns about their effectiveness, acceptability, and efficacy., Objective: The aims of the study were to assess the quality of popular nutrition-related app platforms in Spain and to describe their characteristics and functionalities., Methods: We screened apps providing information on dietary advice, food advice, and nutritional content in the Apple App Store and Google Play Store in Spain from March 2 to March 16, 2024. Apps with a star rating of ≥4 (of 5 stars), those available in Spanish, those that were free of charge, those last updated after January 2022, those with >500 reviews, and those with >500,000 downloads were included. The quality of apps was assessed using the user version of the Mobile App Rating Scale (uMARS). General characteristics and nutritional, health, and market-related functionalities of the nutrition-related apps were described. Correlations among total and uMARS sections, star ratings, and number of reviews and downloads were evaluated., Results: Among the 1460 apps identified in the search, 42 apps met the criteria. The majority of these (n=20, 48%) aimed at recording and analyzing food intake, followed by those providing nutritional plans or diets (n=9, 21%), advising on healthy habits (n=7, 17%), and offering recipes (n=6, 14%). The most prevalent nutritional functionalities offered were recording and monitoring body measurements (n=30, 71%), food tracking (n=26, 62%), and dietary analysis (n=25, 60%), whereas nutrition education was less common (n=16, 38%). Among market-related functionalities, advertisements were the most common among the study apps (n=30, 71%), followed by the option of sharing on social media (n=29, 69%) and customizable reminders (n=26, 62%). Sharing the recorded information in the app with health professionals was infrequent (n=1, 2%). The mean (SD) total uMARS score (maximum 5 points) was 3.78 (0.35), while the mean (SD) uMARS scores for functionality, aesthetics, engagement, and information were 4.21 (0.38), 3.94 (0.54), 3.51 (0.46), and 3.48 (0.44), respectively. Lower mean scores were observed for the subjective quality (mean 2.65, SD 0.56) and perceived impact (mean 3.06, SD 0.67). Moderate to strong positive significant correlations were mostly observed between total uMARS and section-specific uMARS scores, while the correlations between the uMARS section scores were mostly moderate positive. Total uMARS scores were very weakly correlated with user rating, number of reviews, and number of downloads., Conclusions: The quality of popular nutrition-related app platforms in Spain was acceptable, with observed remarkable differences between sections. The majority of the apps were appealing due to their user-friendly interfaces. Only a few apps, however, provided dietary structure analysis or nutritional education. Further research is needed to assess the long-term impact of these apps on users., (© Cesar I Fernandez-Lazaro, Gema Santamaría, Annika Fernandez Milano, Maria Isabel Martin-Vergel, Diego Fernandez-Lazaro.

The residual intake and gain (RIG) aims to select animals that present low feed intake in relation to the expected. This study aimed to evaluate the associations of selection for RIG with performance and carcass traits in Nellore cattle. Initially, residual feed intake (RFI) and residual gain (RG) were determined. From this, the RIG was calculated, and the animals were classified as efficient and inefficient for RIG. The efficient animals for RIG showed higher daily weight gain (DWG), Longissimus muscle area (LMA), and mid-test metabolic body weight (MMBW) than the inefficient ones. No significant correlations were found between subcutaneous fat thickness (SFT), marbling (MAR), LMA, MMBW, and the RIG. Thus, it's concluded that the RIG is a measure that can be used to identify and select animals with higher rates of DWG and LMA without changes in the dry matter intake (DMI), SFT, and MAR. However, this index should still be observed with caution, as it may be dependent on body size. Based on the findings, the selection of animals according to the RIG can be an important factor to generate phenotypic evolution in characteristics such as weight gain and rib eye area without adverse effects on the carcass fat deposition., (© 2024.

Background: It is recommended that postpartum women undergo early oral feeding (EOF) after cesarean section (CS). However, the optimal early time for oral feeding after CS is unclear. We performed a meta-analysis to assess whether EOF within two hours is superior to delayed oral feeding (DOF) after CS., Methods: The PubMed, Embase, Cochrane Library, and Google Scholar databases were searched from inception to February 2024 for randomized controlled trials comparing EOF versus DOF after CS. Primary outcomes included the time to normal bowel function. The secondary outcomes included postoperative complications, the time to ambulation after surgery, the time to removal of the catheter, the time to start of a regular diet, the length of hospital stay and patient satisfaction., Results: Data from 8 studies involving a total of 2572 women were obtained. EOF within two hours was significantly associated with shorter durations of return bowel movement (WMD, - 2.41, 95% CI, - 3.80-- 1.02; p < 0.001; I 2  = 96%), passage flatus after surgery (WMD, - 3.55, 95% CI, - 6.36-- 0.75; p = 0.01; I 2  = 98%), ambulation after surgery (WMD, - 0.96, 95% CI, - 1.80-- 0.13; p = 0.02; I 2  = 53%), removal of catheters (WMD, - 15.18, 95% CI, - 25.61-- 4.74; p = 0.004; I 2  = 100%) and starting a regular diet (WMD, - 7.03, 95% CI, - 13.13-- 0.92; p = 0.02; I 2  = 99%) compared with DOF. EOF was not related to increased vomiting (RR, 1.08; 95% CI, 0.74-1.57; p = 0.69; I 2  = 0%), nausea (RR, 1.21; 95% CI, 0.83-1.77; p = 0.33; I 2  = 37%), abdominal distension (RR, 0.76; 95% CI, 0.31-1.89; p = 0.55; I 2  = 54%) or ileus (RR, 0.91; 95% CI, 0.40-2.06; p = 0.81; I 2  = 12%)., Conclusions: This meta-analysis provides evidence that EOF within two hours after CS has comparable safety with DOF, and can accelerate the recovery time for normal bowel function., Trial Registration: INPLASY202320055., (© 2024.

The aim of this study was to evaluated the impact of different fibre levels in alpaca diet on voluntary feed intake and apparent digestibility, and to estimate the digestibility of organic matter (OMD) from the content of crude protein (CP) in feces. The study was carried out with twelve alpacas (36.7 ± 6.4 kg body weight- BW), which were offered 4 treatments with different neutral detergent fiber content (NDF. T1: 40.3%; T2: 62%; T3: 68%; T4: 72%) under a switch back design. Absolute daily dry matter intake (DMI) was higher for T1 (678 g/d) than T4 (312 g/d) (p ≥ 005). NDF intake was similar between treatments when related to BW or MW (on average 1% BW and 22 g/kg MW. p ≥ 0.05). Water intake (L/kg DMI) was higher in T1 compared to the other treatments, with values ranging from 2.9 L/kg DMI(T1) to 2.8 L/kg DMI(T4), respectively (p ≤ 0.05). Digestibility of dry matter, organic matter and CP was higher in T1 than in the other treatments, with average values ranging from 72% for T1 to 32% for T4 (p ≤ 0.05). NDF digestibility was similar among treatments (p ≥ 0.05). The regression equation generated to predict OMD (y) was as follows: y = 0.360 + 0.08294*fecal CP (g/kg OM). Further studies will indicate whether faecal nitrogen can be used to estimate digestibility and hence diet quality in South American camelids., (© 2024. The Author(s).)

In this paper, I explore the relationship between food and eating in two Abrahamic faiths, viz. Islam and Christianity. I show how these religions create provisions that entreat followers to consume in an ecologically conscientious manner that is not only good for the consumers but for the society and planet as well. In effect, traditional symbolic systems such as religions that provide "magical solutions" can also provide modern solutions to modern crises confronting modern societies in today's world. I argue that Islam and Christianity are highly relevant in today's world where they provide for safe, healthy, and socially conscientious living., (© 2024.

Two burrowing clam species, namely Meretrix meretrix and Paphia undulata, were offered two sizes (small: 45-53 μm, and large: 106-125 μm) of fluorescent red polyethylene microbeads, and the ingestion (number of MPs in the body tissue and faeces) and rejection (number of MPs in pseudofaeces) of MPs investigated. Overall, MP beads ingested were 36 % more than those rejected. There was also a significant interaction between the size and fate of MPs. For both species, significantly more small beads were ingested than rejected, but there was no difference for the large beads. P. undulata ingested more MPs than M. meretrix and both species could depurate all the ingested MPs in 72 h, although a longer time was needed for the former species. The results can provide guidance on seafood selection and pre-treatment to minimize the number of MPs ingested by humans., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Polychlorinated dibenzo- p -dioxins and dibenzofurans (PCDD/Fs) are ubiquitous in the environment. The main route of human exposure is through food consumption. Soil contamination can be problematic for sanitary safety depending on the usage of the soil, such as farming. In case of environmental soil contamination with PCDD/Fs, hen's eggs may be contaminated due to soil ingestion by hens. For this reason, it is important to understand the parameters that influence eggs' contamination when hens are raised in contaminated areas. After the discovery of a contaminated area in Lausanne (Switzerland), we collected hens' eggs from ten domestic-produced eggs and one farm. Based on PCDD/F measurements of eggs and soil, and a toxicokinetic model, we estimated individual hen's soil intake levels and highlighted appropriate parameters to predict the dose ingested. Recommended weekly consumption for home-produced eggs was calculated based on the tolerable weekly intake proposed by EFSA in 2018. The most important parameter to assess the soil ingestion does not seem to be the soil coverage by vegetation but rather the hen's pecking behaviour, the latter being difficult to estimate objectively. For this reason, we recommend using a realistic soil ingestion interval to assess the distribution of egg PCDD/F concentration from free-range hens reared on contaminated soil. The addition of soil contamination in the toxicokinetic model can then be used to recommend to the general population weekly consumption of eggs. The consumption by adults of free-range eggs produced on land with soil containing >90 ng toxic-equivalent (TEQ)/kg dry soil should be avoided. Even with a low level of soil contamination (1-5 ng TEQ/kg dry soil), we would recommend consuming not more than 5 eggs per week for adults and no more than 2 eggs for children below 4 years old.

Dietary carbohydrate manipulation can be used to reduce enteric CH 4 emission, but few studies have focused on the interaction of the different types of carbohydrates that can affect feed intake and ruminal fermentation. Understanding this interaction is necessary to make the most out of CH 4 mitigation feeding strategies using different dietary carbohydrates. The aim of this study was to test the effect on enteric CH 4 emission, feed intake, and milk production response when cows were fed either grass-clover silage (GCS) or corn silage (CS) as the sole forage source (55% of dry matter, DM), in combination with either barley (BAR) or dried beet pulp (DBP) as a concentrate (21.5% of DM). A total of 24 (half first-parity and half second-parity) cows were used in a crossover design with 2 periods of 21 d each, receiving 2 of 4 diets obtained from a 2 × 2 factorial arrangement of the experimental diet. Feed intake, CH 4 emission metrics, and milk production were recorded at the end of the experimental periods. The diets had NDF concentrations between 258 and 340 g/kg of DM and starch concentrations between 340 and 7.45 g/kg of DM (CS-BAR and GCS-DBP, respectively). The effects of silage and concentrate on dry matter intake (DMI) were additive, with the highest feed intake in cows fed CS-BAR, followed by cows fed CS-DBP, GCS-BAR, and GCS-DBP (21.2, 19.9, 19.1, and 18.3 kg/d, respectively). Energy corrected milk (ECM) yield was not affected by silage source in first parity cows, but it was higher for cows fed CS than cows fed GCS in second parity. The effects of silage and concentrate on CH 4 production (g/d), yield (g/kg of DMI), and intensity (g/kg of ECM) were not additive, as cows fed GCS had similar responses regardless of the concentrate used, but cows fed CS had lower CH 4 production, yield, and intensity when fed BAR instead of DBP. The lower CH 4 production, yield, and intensity in cows fed CS-BAR compared with other diets could be partially explained by the nonlinear relationship between ruminal VFA and carbohydrates (NDF and starch) concentration reported in the literature; however, we observed a linear relationship between the acetate/propionate ratio and CH 4 yield, suggesting possible other effects. The effects of silage and concentrate on the ruminal VFA were additive in first parity cows, but not in second parity cows. The interaction between dietary carbohydrate type and parity might indicate an effect of feed intake or the energy balance of the cow. Feeding cows silage and concentrate both rich in starch can result in the lowest enteric CH 4 emission., (The Authors. Published by Elsevier Inc. on behalf of the American Dairy Science Association®.

Background: Wearing complete denture in one or both arches can impact enjoyment of eating and affect quality of life compared with being dentate. Clinicians focus on issuing technically sound dentures but ignore the impact of wearing dentures on the eating-related quality of life which affects the success of treatment., Objectives: The aim of this research was to qualitatively explore ERQoL in Australian adults wearing complete dentures using a validated questionnaire and through focus groups., Methods: Complete denture wearers (n = 44) were recruited from dental clinics and invited to complete the self-administered Emotional and Social Issues Related to Eating questionnaire. Responses were categorised under the six questionnaire domains. A subsample of 20 participants who completed the questionnaire were invited to participate in focus groups to identify emerging themes., Results: Twenty-three participants (52.3%) completed the questionnaire. Most participants expressed a decline in enjoyment of eating due to reduced ability to eat, longer chewing times and the need to frequently clean dentures while eating. Focus groups (n = 2 × 4 participants) indicated educational materials on eating with dentures would increase recognition of eating problems with dentures and reduce trial and error approaches to dealing with these., Conclusion: ERQoL is adversely affected by wearing complete dentures due to functional limitations, restricted food choices and adaptive eating behaviours. Patient support for eating well with a complete denture/s wearers is required., (© 2024 The Author(s). Journal of Oral Rehabilitation published by John Wiley & Sons Ltd.)

Oral ulcers induce acute weight loss due to anorexia in foot-and-mouth disease virus (FMDV) infected cattle. We hypothesized that providing a palatable form of a therapeutic diet (TD) in different physical forms would increase the feed intake, digestibility and restoration of body weight. A TD was formulated with 19% CP and 2.9 Mcal ME/kg on dry matter basis. Bull calves of 10-12 months with mean body weight of 123 ± 1.3 kg were experimentally infected with FMDV (n = 18) and offered one of the following three forms of the TD (n = 6/group) for 6 weeks post-FMDV infection (WPI): (i) TD in mash form (TD M ) (ii) TD in cooked form (TD C ) and (iii) TD C + customised nutrient supplement (TD CNS ) such as Zn, Cu, Cr, Mn, and Se. The CNS was fed before the TD C. A group of uninfected control (n = 4) was fed TD M. Green fodder was offered in the afternoon. Dry matter intake (DMI) of TD and green fodder were recorded at 24 h interval till WPI 6. Body weight (BW) was recorded at weekly interval. Digestibility trial was conducted at WPI 6. The palatability of the TD was scored from 1- 4 and healing of tongue ulcers was analyzed by Kaplan-Meier survival curve. The results indicated that the physical form of TD increased the total DMI by WPI 3, which was supported by the restoration of BW and higher palatability score. The digestibility of all the proximate principles except EE was significantly higher (P < 0.05) in the groups that were fed TD C . It was concluded that feeding TD irrespective of the physical form, restored the ADG and DMI in the calves by WPI 3. Further, feeding cooked form of TD increased the digestibility in the FMDV infected calves and supplementation of CNS hastened the healing of glossal ulcers., (© 2024.

Feed efficiency is important for economic profitability of dairy farms; however, recording daily DMI is expensive. Our objective was to investigate the potential use of milk mid-infrared (MIR) spectral data to predict proxy phenotypes for DMI based on different cross-validation schemes. We were specifically interested in comparisons between a model that included only MIR data (model M1); a model that incorporated different energy sink predictors, such as body weight, body weight change, and milk energy (model M2); and an extended model that incorporated both energy sinks and MIR data (model M3). Models M2 and M3 also included various cow-level variables (stage of lactation, age at calving, parity) such that any improvement in model performance from M2 to M3, whether through a smaller root mean squared error (RMSE) or a greater squared predictive correlation (R 2 ), could indicate a potential benefit of MIR to predict residual feed intake. The data used in our study originated from a multi-institutional project on the genetics of feed efficiency in US Holsteins. Analyses were conducted on 2 different trait definitions based on different period lengths: averaged across weeks versus averaged across 28 d. Specifically, there were 19,942 weekly records on 1,812 cows across 46 experiments or cohorts and 3,724 28-d records on 1,700 cows across 43 different cohorts. The cross-validation analyses involved 3 different k-fold schemes. First, a 10-fold cow-independent cross-validation was conducted whereby all records from any one cow were kept together in either training or test sets. Similarly, a 10-fold experiment-independent cross-validation kept entire experiments together, whereas a 4-fold herd-independent cross-validation kept entire herds together in either training or test sets. Based on cow-independent cross-validation for both weekly and 28-d DMI, adding MIR predictors to energy sinks (model M3 vs. M2) significantly (P < 10 -10 ) reduced average RMSE to 1.59 kg and increased average R 2 to 0.89. However, adding MIR to energy sinks (M3) to predict DMI either within an experiment-independent or herd-independent cross-validation scheme seemed to demonstrate no merit (P > 0.05) compared with an energy sink model (M2) for either R 2 or RMSE (respectively, 0.68 and 2.55 kg for M2 in herd-independent scheme). We further noted that with broader cross-validation schemes (i.e., from cow-independent to experiment-independent to herd-independent schemes), the mean and slope bias increased. Given that proxy DMI phenotypes for cows would need to be almost entirely generated in herds having no DMI or training data of their own, herd-independent cross-validation assessments of predictive performance should be emphasized. Hence, more research on predictive algorithms suitable for broader cross-validation schemes and a more earnest effort on calibration of spectrophotometers against each other should be considered., (The Authors.

Acute stressors tend to shift preferences toward comfort foods, yet they do not ubiquitously increase the amount of food consumed. Moreover, although many individuals eat more under stress, others eat less or show no change. Although the precise mechanisms explaining this variability in stress-related eating are unknown, they may be driven by individual differences in the rewarding effects of comfort eating, which are enhanced by greater lifetime stressor exposure. To investigate this possibility, we examined whether differences in lifetime stressor exposure predicted reductions in negative affect following snacking (i.e., negative reinforcement) and if this effect was specific to stress-related snacking or snacking in general. Participants were 26 women (23 % non-White) between 20 and 45 years old (M = 31), with a mean body mass index of 26, who completed three laboratory visits. Participants completed an assessment of lifetime stressor exposure (i.e., STRAIN) on the first visit and, on two subsequent laboratory visits in counterbalanced order, were given snacks after an acute social stress task (i.e., TSST) or rest period. Greater lifetime stressor exposure was related to greater post-ingestive decreases in negative affect following the acute social stressor but not following the rest period. If stress-related eating is more comforting for women with greater lifetime stressors and contributes to a stronger stress-eating association, then this may inform obesity-related clinical treatments that target behaviors and cognitions related to reward-based learning., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest with respect to this work., (Copyright © 2024 Elsevier Inc.

Middle-aged obesity and aging anorexia with muscle loss (sarcopenia) of old people present public health burden. These alterations may appear both in humans and rodents suggesting the role for regulatory alterations. Previously, we demonstrated that biphasic changes in the weight-reducing (catabolic) effects of neuropeptides of the hypothalamus-adipose tissue axis (e.g. leptin) may contribute to both trends. With regard to the anabolic effects of the hypothalamic neuropeptide Y (NPY) inhibited by leptin, we hypothesized non-linear age-related changes with shifts in the opposite directions. We investigated the orexigenic and hypometabolic effects of intracerebroventricularly administered NPY (hyperphagia induced by NPY injection or changes in food intake, body weight, heart rate, body temperature, locomotor activity during a 7-day NPY infusion), the immunoreactivity and gene expression of NPY in the hypothalamic arcuate nucleus of male Wistar rats of five age groups from young to old. The orexigenic/hypometabolic efficacy and the immunoreactivity of NPY increased in middle-aged animals preceding the peak of adiposity observed in aging rats, then decreased preceding anorexia and weight loss in old rats. These shifts may contribute to the development of both age-related obesity and aging anorexia, sarcopenia, and should be considered in future drug development targeting the NPY system., (© 2024.

Background: Early-life food consumption patterns may affect children's health by increasing susceptibility to developing non-communicable chronic diseases (NCDs) in adulthood., Aims: To evaluate Jordanian children and adolescents' energy and macronutrient intake and how closely they adhere to dietary recommendations., Methods: This cross-sectional study used data from Jordan's Population-based Food Consumption Survey, a household population-based study conducted in Jordan between 2021 and 2022 (561 children and adolescents 8-19 years). Dietary intake was assessed using the two non-consecutive 24-hour dietary recall methods (24-h DR). The estimated food group and nutrient intakes were compared to nutritional recommendations, including MyPlate dietary guidelines., Results: The prevalence of overweight/obese individuals based on body mass index (BMI) was 44%, and the average waist-to-height ratio (WHtR) was 24.7%. Compared to MyPlate dietary guidelines, children and adolescents had a higher added sugar intake (57g/day). Also, consuming vegetables, fruits, and dairy fell short of MyPlate dietary guidelines. The total discretionary calorie intake in children and adolescents was approximately one-third of the total energy intake., Conclusion: The food consumption of Jordanian children and adolescents includes high intakes of discretionary calories, with a low intake of fruits, vegetables, and dairy products. The prevalence of overweight/obesity was elevated compared to international norms., Competing Interests: No competing interests were disclosed., (Copyright: © 2024 Alkhatib B et al.)

The present study evaluated the effects of weaning strategy on piglet growth performance, onset of feed intake, and intestinal health. A total of 254 crossbred piglets were used and the experimental period lasted 45 days. The piglets were assigned to the fallowing treatments: early strategic weaning (ESW, n = 85), piglets weaned at 16 days of age and transferred to the pre-nursery unit; strategic segregated weaning (SSW, n = 85), piglets weaned at 21 days of age and kept in the farrowing crate until 24 days of age; and conventional weaning (CW, n = 84), piglet weaned at 24 days of age and transferred directly to the nursery unity; this experimental group was used as a control. Piglets from all treatments were transferred to the nursery unit at 24 days of age. For the nursery phase three periods of evaluation was considered: nursery phase I (0-7 d), nursery phase II (7-14 d), and nursery phase III (14-21 days). Piglets from the ESW and CW had greater (P < 0.001) ADG in the lactation period 16-21 days. The BW at 24 day of age was higher (P < 0.001) for piglets in the ESW and CW groups. In the nursery phase I, the ESW group had higher (P = 0.003) daily feed intake. Piglets from the ESW group had higher (P = 0.004) BW at the end of the experimental period. The ESW and SSW groups had a higher percentage of piglets (88% and 92%, respectively; P < 0,001) consuming feed in the first 24 h after transference to the nursery facility. When the total experimental period is considered, a reduction (P < 0.001) in the incidence of diarrhea was observed for ESW piglets. Overall, there was no effect of weaning strategy on intestinal permeability. In conclusion, the results of our study showed that the Segregated Strategic Weaning management can be used to mitigate the deleterious effects of early weaning., (© 2024.

(1) Background: "Blue food" is a recently coined term referring to seafood, emphasizing health benefits and sustainability. This study compares nutrient intake levels between Koreans who consume fish and shellfish and those who do not. (2) Methods: Data from the eighth Korea National Health and Nutrition Examination Survey (2019-2020) were used. A total of 9442 individuals were analyzed (≥1 year old). A complex sample design was applied. (3) Results: Younger individuals aged 9 to 29 consumed less fish and shellfish, while those with higher education and income levels consumed more. Compared with the non-consumption group, individuals in the fish and shellfish consumption group exhibited a higher nutrient density in their diets, excluding total fat, saturated fatty acids, monounsaturated fatty acids, and riboflavin ( p < 0.01). They also had a higher proportion of nutrient intakes relative to the Recommended Nutrient Intake level for all nutrients than the non-consumption group ( p < 0.001), particularly in eicosapentaenoic acid and docosahexaenoic acid intakes. Conversely, the non-consumption group had a higher proportion of nutrient intakes below the Estimated Average Requirement compared with the consumption group. ( p < 0.001). (4) Conclusions: Individuals consuming blue food exhibited higher levels of nutrient intake. Developing strategies to promote the consumption of blue food, considering factors such as age, education, and income, is essential.

Background: The Cannabis Eating Experience Questionnaire (CEEQ) was developed and validated with a two-factor structure for the assessment of cannabis effects on both the appetitive factors that initiate eating and the hedonic factors that maintain an eating episode. The relationship between the CEEQ and cannabis use motives has not yet been considered. The study aimed to confirm the two-factor structure of the CEEQ and explore associations with the five-factor Marijuana Motives Questionnaire (MMQ)., Method: Cannabis users ( N  = 546) completed the CEEQ alongside the MMQ in an online survey., Results: Confirmatory factor analysis (CFA) confirmed the two-factor structure of the CEEQ and the five-factor structure of the MMQ. Structural equation modeling (SEM) tested associations between each factor of the CEEQ and cannabis use motives. Cannabis use motives of "enhancement" and "conformity" were both positively associated with "hedonic" and "appetitive" subscales of the CEEQ, and "coping" was associated with increased "appetitive" scores. The "social" cannabis use motive was negatively associated with both "hedonic" and "appetitive" subscales on CEEQ, and "expansion" was negatively associated with the "appetitive" subscale., Conclusion: We provide further support for the construct validity of the CEEQ that provides a useful assessment of cannabis effects on hedonic and appetitive aspects of eating and show for the first time that cannabis use motives influence eating experiences in distinct ways. Further understanding of the relationship between cannabis use motives and the effects of cannabis on appetite may prove a useful for informing therapeutic applications of cannabis stimulating appetite or promoting weight gain.

It is widely accepted that birds can adaptively regulate body mass in different ecological contexts, but little is known about how birds monitor and interpret their body mass or the mechanisms that allow for rapid changes in mass. Using captive zebra finches (Taeniopygia guttata), we experimentally increased perceived mass via attachment of weighted backpacks and provided birds with either an ad libitum mixed-seed diet or supplementary high-fat diet to investigate: (1) how birds assess their own body mass and (2) the physiological and/or behavioral mechanisms birds may employ to rapidly adjust body mass. In both experiments, and independent of diet treatment, birds with weighted backpacks rapidly lost mass within 2 days of backpack attachment while reducing overall activity and maintaining food intake. Additionally, our data suggest that birds interpret body mass via a physical mechanosensory pathway rather than a physiological pathway: rapid loss of mass between days 0 and 2 was not linked to changes in plasma metabolites (glycerol or triglyceride concentrations). We found no evidence that mass loss was a consequence of stress associated with attachment of weighted backpacks (based on plasma corticosterone measures). Our results suggest that the processes of energy balance and mass regulation involve a greater array of mechanisms than simply matching 'energy in', through the amount of food consumed, to 'energy out', dictated by activity. Zebra finches were able to decrease body mass through other, unidentified, mechanisms even while maintaining dietary intake and reducing overall activity., Competing Interests: Competing interests The authors declare no competing or financial interests., (© 2024.

Background: Diet-related diseases, such as type 2 diabetes, require strict dietary management to slow down disease progression and call for innovative management strategies. Conventional diet monitoring places a significant memory burden on patients, who may not accurately remember details of their meals and thus frequently falls short in preventing disease progression. Recent advances in sensor and computational technologies have sparked interest in developing eating detection platforms., Objective: This review investigates central hemodynamic and thermoregulatory responses as potential biomarkers for eating detection., Methods: We searched peer-reviewed literature indexed in PubMed, Web of Science, and Scopus on June 20, 2022, with no date limits. We also conducted manual searches in the same databases until April 21, 2024. We included English-language papers demonstrating the impact of eating on central hemodynamics and thermoregulation in healthy individuals. To evaluate the overall study quality and assess the risk of bias, we designed a customized tool inspired by the Cochrane assessment framework. This tool has 4 categories: high, medium, low, and very low. A total of 2 independent reviewers conducted title and abstract screening, full-text review, and study quality and risk of bias analysis. In instances of disagreement between the 2 reviewers, a third reviewer served as an adjudicator., Results: Our search retrieved 11,450 studies, and 25 met our inclusion criteria. Among the 25 included studies, 32% (8/25) were classified as high quality, 52% (13/25) as medium quality, and 16% (4/25) as low quality. Furthermore, we found no evidence of publication bias in any of the included studies. A consistent postprandial increase in heart rate, cardiac output, and stroke volume was observed in at least 95% (heart rate: 19/19, cardiac output: 18/19, stroke volume: 11/11) of the studies that investigated these variables' responses to eating. Specifically, cardiac output increased by 9%-100%, stroke volume by 18%-41%, and heart rate by 6%-21% across these studies. These changes were statistically significant (P<.05). In contrast, the 8 studies that investigated postprandial thermoregulatory effects displayed grossly inconsistent results, showing wide variations in response with no clear patterns of change, indicating a high degree of variability among these studies., Conclusions: Our findings demonstrate that central hemodynamic responses, particularly heart rate, hold promise for wearable-based eating detection, as cardiac output and stroke volume cannot be measured by any currently available noninvasive medical or consumer-grade wearables., Trial Registration: PROSPERO CRD42022360600; https://www.crd.york.ac.uk/prospero/display&#95;record.php?RecordID=360600., (©Lucy Chikwetu, Parker Vakili, Andrew Takais, Rabih Younes.

The objectives of this research were to assess ingested plastics and accumulated heavy metals in four urban gull species. Additionally, the relationships between ingested plastics and selected demographic and health metrics were assessed. Between 2020-2021 during the non-breeding seasons, 105 gulls (46 American herring gulls (HERG, Larus argentatus smithsonianus), 39 great black-backed gulls (GBBG, Larus marinus), 16 Iceland gulls (Larus glaucoides), 4 glaucous gulls (Larus hyperboreus)) were killed at a landfill in coastal Newfoundland and Labrador, Canada, as part of separate, permitted kill-to-scare operations related to aircraft safety. Birds were necropsied, the upper gastrointestinal tract contents were processed using standard techniques, and livers were analyzed for accumulated As, Cd, Hg, and Pb. The relationships between ingested plastics, demographics, and health metrics were assessed in HERG and GBBG. Across all four species, 85 % of birds had ingested at least one piece of anthropogenic debris, with 79 % ingesting at least one piece of plastic. We detected interspecific differences in plastic ingestion and hepatic trace metals, with increased ingested plastics detected in GBBG compared with HERG. For GBBG, levels of ingested plastic were relatively greater for birds with higher scaled mass index, while HERG with more ingested plastic had higher liver lead concentrations., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

The purpose of this retrospective study was to identify factors that could predict the discharge destination of oldest-old patients (patients aged ≥90 years). Information on the nutritional status, activities of daily living (ADL), nursing care needs based on nursing need degree (NND), rehabilitation therapy, and discharge destination was obtained from the medical records of 90 oldest-old patients aged ≥90 years admitted to our hospital, excluding orthopedic inpatients and short-term (≤5 days) inpatients. Of these, 64 were discharged home while 4 died during hospitalization. More than half had moderately low total lymphocyte count (<1200/μL). Home discharge was correlated with living with someone else and little need for assistance during eating and getting/standing-up at admission. The cutoff value for ability for basic movement scale (ABMS) at admission for home discharge was 18 points. Nutritional management and early mobilization are important aspects of clinical management of the oldest-olds., Competing Interests: Declaration of competing interest All authors declare no conflict of interest., (Copyright © 2024 Elsevier Inc.

A conventional questionnaire-based assessment of acetic acid intake is based on the intake of seasonings such as mayonnaise, which could thereby lead to an underestimation. We here determine the relationships of acetic acid intake with nutrient intake estimated using a food recording app (Asken) based on meal recipes. A total of 141 individuals (48 men and 93 women) used the app for at least 7 days per month. The mean daily intake of acetic acid was 0.16 ± 0.19 g and the mean frequency of acetic acid intake was 2.77 ± 1.66 days per week. A multivariate regression analysis adjusted for age, sex, BMI, and energy intake revealed that the amount of acetic acid consumed was significantly and positively associated with the intake of protein (11.9 (5.1, 18.6), p < 0.001), cholesterol (80.7 (4.5, 156.9), p = 0.04), and all vitamins except vitamin K. The frequency of acetic acid intake was significantly and positively associated with protein (1.04 (0.20, 1.87), p = 0.015), vitamin B1 (0.3 (0.02,0.5), p = 0.031), niacin (0.5 (0.04,1.0), p = 0.032), and vitamin B12 (0.4 (0.1,0.7), p = 0.002) intake, suggesting that individuals who frequently consume acetic acid tend to consume more protein and some vitamins. Thus, the amount and frequency of acetic acid may reflect protein and vitamin intake.

Background: Weight stigma refers to the social rejection, discrimination, and ideological devaluation of individuals because of body size and is a direct result of weight bias and anti-fat attitudes. Individuals with higher weight may be less likely to seek healthcare due to weight stigma, and if or when they do present for care, medical providers with weight bias may fail to provide high quality care. Little, however, is known about the intersectionality of weight stigma and perceptions of healthcare interactions as experienced by individuals who also binge eat., Methods: Community-based adults completed online self-report questionnaires regarding generalized weight stigma (Attitudes Towards Obese Persons 1 ), healthcare interaction quality (Patient Perceptions of Healthcare Provider Interaction Quality; PPH), and disordered eating (Eating Disorder Examination-Questionnaire) via Amazon's Mechanical Turk platform. For this cross-sectional study, participants were categorized by the presence and absence of regular binge episodes. Pearson's correlations, T-tests, ANOVA/ANCOVA, and a multivariate regression were used to examine relationships among demographic variables, weight stigma, disordered eating, and the PPH., Results: Participants (N = 648) primarily identified as female (65.4%) and White, non-Hispanic (72.7%). Participants' average age and body mass index (BMI) were 37.5 (SD = 12.3) years old and 27.3 (SD = 6.9) kg/m2, respectively. Higher healthcare provider interaction quality ratings (PPH) were significantly related to lower BMI (r(648)=-0.098,p = 0.012), less weight stigma (r(648) = 0.149,p < 0.001), and identifying as a woman (t(514) = 2.09, p = 0.037, Cohen's d = 0.165) or White, non-Hispanic (t(646)=-2.73, p = 0.007, Cohen's d=-0.240). Participants reporting regular binge eating endorsed significantly worse perceptions of healthcare provider quality than those who did not, even after accounting for BMI, F(1, 645) = 8.42, p = 0.004, η2 = 0.013. A multivariate linear regression examining the PPH as dependent, and weight stigma and binge eating as independent, variable/s, was significant even after accounting for covariates (sex, race, BMI), F(95, 640) = 7.13,p < 0.001, R 2  = 0.053 (small effect)., Conclusions: More negative experiences with healthcare providers was associated with worse weight stigma, higher BMI, regular binge eating and overall disordered eating, and for participants identifying as male or a Person of Color. These data have implications for non-clinical community populations and are particularly important as experiencing poorer quality of interactions with healthcare providers may decrease individuals' likelihood of seeking needed care for both disordered eating and health-related concerns., Trial Registration: N/A., (© 2024.

This study examines observers' perceptions of employees eating during virtual work meetings. Using a 2 × 3 experimental design, participants ( N  = 842) were randomly assigned to one of three eating conditions including no one eating, target eating, and everyone eating where they rated either a male or female target. While existing research has demonstrated positive consequences of sharing food in the traditional workplace, our findings demonstrate that individuals who eat during virtual work meetings are perceived as less professional, less competent, and less likely to experience career success. Observers' perceptions of the eater's professionalism are negatively impacted, regardless of whether the target is the only one eating or whether everyone is eating. We offer practical suggestions for HRM professionals working to help managers and employees understand the nuances of videoconferencing.

Objective: To explore the relationship between triglyceride-glucose index(triglyceride-glucose index) and food intake and the comprehensive compliance rate in patients with type 2 diabetes mellitus(T2DM)., Methods: A total of 6683 T2DM patients aged 18 to 75 years entered the National Metabolic Management Center(MMC) in two Yancheng hospitals from August 2020 to November 2023 were selected to analyze the relationship between T2DM standard attainment rate and relevant indicators. Univariate analysis was conducted with χ~2 test, multivariate analysis was conducted with stepwise logistic regression model, and the relationship of TyG to the overall compliance rate of T2DM was analyzed with restricted cubic spline(Restricted Cubic Spline, RCS)., Results: T2DM patients with glycated hemoglobin Hemoglobin A1c(HbA1c) reached 9.01%, blood pressure(BP) reached 29.21%, low density lipoprotein cholesterol(LDL-C) reached 28.51%, and the comprehensive standard rate was 1.14%. TyG index was the hindering factor affecting the comprehensive standard rate of T2DM. The higher the TyG value, the lower the standard rate. Comprehensive compliance rate and fresh fruit intake(χ~2=32.946, P&lt;0.001) and salt intake(χ~2=41.917, P&lt;0.001) was closely related, and the fruit intake of 200-400 g helped to improve the comprehensive compliance rate of T2DM patients., Conclusion: TyG index, fruit intake and salt intake may be the influencing factors of comprehensive compliance rate.

To properly formulate diets, the ability to accurately estimate feed intake is critical as the amount of feed consumed will influence the amount of nutrients delivered to the animal. Inaccurate intake estimates may lead to under- or over-feeding of nutrients to the animal. Individual differences in equine forage intake are well-known, but predictive equations based on animal and nutritional factors are not comprehensive. The objective of the present study was to consolidate the current body of knowledge in the published literature on voluntary forage DM intake (VFDMI) in equines and conduct a meta-analysis to identify driving factors, sources of heterogeneity, and develop predictive equations. Therefore, a systematic literature search was applied and identified 61 publications which met the inclusion criteria. From each study, the outcomes of interest (e.g., forage intake), diet composition (e.g., forage information, nutrient composition), and animal factors (e.g., sex, age, breed, BW, exercise level) were extracted. Forage intake was analyzed as two different outcome variables: (1) VFDMI in kg/d and (2) VFDMI in g/kg BW. Linear mixed model analysis treating study as a random effect was applied, using a backward-stepping approach to identifying potential driving variables for VFDMI (both units) where all terms have P < 0.1. The best fitting models for VFDMI included similar factors (also across kg/d and g/kg BW) such as forage quality (i.e., neutral detergent fiber or CP content), forage type (i.e., grass, legume, or mixed), the animals' size category (i.e., horses vs ponies), and some management factors (i.e., pasture access). As anticipated, forage intake increased when higher quality forages were fed (i.e., lower neutral detergent fiber or higher CP), potentially due to improved digestibility. Additionally, VFDMI increased as BW increased but ponies increased their VFDMI more per every kg increase in BW compared to horses. Lastly, pasture access (i.e., grazing) may influence VFDMI such that pastured animals consume less than stalled animals, possibly due to the time it takes to graze forage. In conclusion, equations to predict equine VFDMI with high accuracy and precision (concordance correlation coefficient  = 0.82 - 0.95; root mean squared error RMSE = 0.82-5.49) were developed which could be applied in practice by equine nutritionists or owners and managers. The results of this meta-analysis confirm that animal traits and forage quality have a significant impact on the VFDMI of equines and should be accounted for when formulating diets to ensure nutritional requirements are met., (Copyright © 2024.

We investigated the contents inside the esophagus and stomach of turtles inside and outside of the Tokyo Bay area, which face high and low risks of microplastic (MP) exposure, respectively. 65 synthetic particles were recovered from 8 out of 22 turtles, using ATR-FTIR followed by density separation with calcium chloride solution. Statistical analysis indicated that turtles in high-risk areas ingested significantly more MPs than those in low-risk areas. As the inflow of MPs from major rivers influences pollution levels in the ocean, the results of this study highlight the importance of major rivers for MP ingestion by turtles. Additionally, we discussed the current methodology's shortcomings and addressed scope for subsequent research, along with suggestions on future conservation., Competing Interests: Declaration of competing interest The authors declare that they have no competing financial interests or personal relationships that may have influenced the work reported in this study., (Copyright © 2024 Elsevier Ltd.

The residual feed intake (RFI) model has recently gained popularity for ranking dairy cows for feed efficiency. The RFI model ranks the cows based on their expected feed intake compared to the observed feed intake, where a negative phenotype (eating less than expected) is favourable. Yet interpreting the biological implications of the regression coefficients derived from RFI models has proven challenging. In addition, multitrait modelling of RFI has been proposed as an alternative to the least square RFI in nutrition and genetic studies. To solve the challenge with the biological interpretation of RFI regression coefficients and suggest ways to improve the modelling of RFI, an interdisciplinary effort was required between nutritionists and geneticists. Therefore, this paper aimed to explore the challenges with the traditional least square RFI model and propose solutions to improve the modelling of RFI. In the traditional least square RFI model, one set of fixed effects is used to solve systematic effects (e.g., seasonal effects and age at calving) for traits with different means and variances. Thereby, measurement and model fitting errors can accumulate in the phenotype, resulting in undesirable effects. A multivariate RFI model will likely reduce this problem, as trait-specific fixed effects are used. In addition, regression coefficients for DM intake on milk energy tend to have more biologically meaningful estimates in multitrait RFI models, which indicates a confounding effect between the fixed effects and regression coefficients in the least square RFI model. However, defining precise expectations for regression coefficients from RFI models or sourcing for accurate feed norm coefficients seems difficult, especially if the coefficients are applied to a wide cattle population with varying diets or management systems, for example. To improve multitrait modelling of RFI, we suggest improving the modelling of changes in energy status. Furthermore, a novel method to derive the energy density of the diet and individual digestive efficiency is proposed. Digestive efficiency is defined as the part of the efficiency associated with digestive processes, which primarily reflects the conversion from gross energy to metabolisable energy. We show the model was insensitive to prior values of energy density in feed and that there was individual variation in digestive efficiency. The proposed method needs further development and validation. In summary, using multitrait RFI can improve the accuracy of the ranking of dairy cows' feed efficiency, consequently improving economic and environmental sustainability on dairy farms., (Copyright © 2024 The Authors.

Aims: To explore the underlying beliefs of preventive health behaviours among women with a history of GDM who had low levels of preventive health behaviours during their postpartum period in Singapore., Methods: This paper reports on the qualitative arm of a mixed method study. The qualitative descriptive design was adopted. Individual interviews were conducted between 7th September 2020 and 25th September 2020 using a semi-structured interview guide. Data collected were analysed using thematic analysis., Results: A total of 18 women completed the interview. The participants' ages ranged from 26 to 40 years with a mean age of 33.17 years (SD= 4.09). The duration since childbirth was 8.78 months (SD = 1.35). Through thematic analysis, five themes were developed: lifestyle adjustment, self-motivation, supportive environment, barriers to practising a healthy lifestyle, and risk perception. A total of 14 subthemes emerged from the five main themes. The beliefs of women with a history of GDM were described according to the Theory of Planned Behaviour., Conclusions: Having a newborn brings changes to the lifestyle of a woman and her family, which can affect the health behaviours in the postpartum period. This study revealed several novel findings relating to the unmet needs of women who had GDM, specifically to the need for information and emotional support to safely resume healthy behaviours after childbirth, for which participants have provided suggestions on how to enhance the continuity of care in the postpartum period., Competing Interests: Declaration of competing interest None., (Copyright © 2024.

Glycomacropeptide (GMP) has a unique amino acid profile which may make less satiating than other dietary proteins. This study assessed the feasibility and likely acceptability of a leucine-enriched GMP drink and determined appetite response in older adults (OA). Thirteen OA (11f; 70 ± 4 years) were recruited for sensory assessments of a leucine-enriched GMP drink when mixed with water and with fruit smoothie, compared with whey protein isolate (WHEY). Participants also partook in a single focus group exploring acceptability to protein and supplementation. Separately, a counterbalanced, double-blind study with twelve OA (8f; 69 ± 3 years) was conducted to determine appetite and gut hormone responses. Fasting subjective appetite was recorded using visual analogue scales and a fasted venous blood sample was collected (to measures acyl-ghrelin, PYY, GLP-1, and CCK) before participants consumed either: GMP protein (27g + 3g leucine, 350 mL water), WHEY (30g, 350 mL water), or water. Participants rested for 240 min, with appetite measures and blood sampling throughout. An ad libitum pasta-based meal was then consumed. Sensory testing revealed low pleasantness rating for GMP in water vs. WHEY (16 ± 14 vs 31 ± 24, p = 0.016). GMP addition to smoothie reduced pleasantness (26 ± 21 vs. 61 ± 29, p = 0.009) and worsened the aroma (46 ± 15 vs. 69 ± 28, p = 0.014). The focus group revealed uncertainty of protein needs and a scepticism of supplements, with preference for food. Gut hormone response did not differ between GMP and WHEY (nAUC for all gut hormones p > 0.05). There was no difference between conditions for lunch ad libitum intake (549 ± 171 kcal, 512 ± 238 kcal, 460 ± 199 kcal for GMP, WHEY, and water, p = 0.175), or for subjective appetite response. Leucine-enriched GMP was not less satiating than WHEY, and low palatability and scepticism of supplements question the likely acceptability of GMP supplementation. Providing trusted nutritional advice and food enrichment/fortification may be preferred strategies for increasing protein intake in OA., Competing Interests: Declaration of competing interest This work was supported by a Pump-Priming Award from the Food 4 Years Network.

This report describes the knowledge mobilization and translation outcomes of the Canadian-funded portion of a large, international project called the Food Biomarker Alliance (FoodBAll), which ran from 2015 to 2019. This remarkably successful project led to a large number of important findings, outputs, and impacts. In particular, FoodBAll unequivocally demonstrated that metabolomics could be used to not only discover biomarkers of food intake (BFIs), but also to measure diet in a more objective manner. FoodBAll also created standards for assessing and validating BFIs, papers and databases describing BFIs, and kits for measuring BFIs and it laid the groundwork for many global studies exploring food composition and precision nutrition., Competing Interests: The author declares no competing interests.

.We present the case of a 46-year-old female with dysphagia to solids and retrosternal pain that worsened after eating. Due to mediastinal lymphadenopathies, she underwent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) 3 weeks before, mentioning the complaints started afterwards. On physical examination she had fever (38.3ºC). Gastroscopy revealed three 10-20mm fistulous orifices with purulent discharge at 26-32cm from the incisors and another four partially covered by fibrin in the distal esophagus. EBUS-TBNA report was reviewed, mentioning 6 needle passes through the esophagus, due to failed endotracheal intubation, without immediate complications. A cervicothoracic CT scan identified 2 mediastinal abscesses, the largest with 9cm, communicating with the esophageal fistulas. She was admitted, underwent intravenous antibiotics and endoscopy-guided nasogastric tube placement. The histopathological analysis diagnosed Castleman's disease. There was clinical and imagological improvement during admission. After 16 days she was released. Upper endoscopy was repeated one month later showing complete closure of the fistulous orifices.

Objective: Proopiomelanocortin (POMC) neurons release potent anorexigenic neuropeptides, which suppress food intake and enhance energy expenditure via melanocortin receptors. Although the importance of central melanocortin in physiological regulation is well established, the underlying genetic mechanisms that define the functional identity of melanocortin neurons and maintain hypothalamic Pomc expression remain to be fully determined. In this study, we investigate the functional significance of Six3, a transcriptional regulator notably expressed in embryonic and adult mouse POMC neurons, in the regulation of hypothalamic Pomc expression and downstream physiological consequences., Methods: We first evaluated the expression of Six3 in the developing and adult hypothalamus by double fluorescence in situ hybridization. Next, we assessed POMC immunoreactivity in mutant mice selectively lacking Six3 from Pomc-expressing neurons and quantified Pomc mRNA levels in a tamoxifen-inducible Six3 knockout mouse model activated at embryonic E9.5 days. We also determined glucose and insulin sensitivity, daily food intake, body composition and body weight in adult male and female mice lacking Six3 specifically from POMC neurons. Lastly, we assessed the physiological consequences of ablating Six3 from POMC neurons in adult mice., Results: Six3 and Pomc were co-expressed in mouse hypothalamic neurons during development and adulthood. Mouse embryos deficient in Six3 showed reduced Pomc expression in the developing hypothalamus. Targeted deletion of Six3 specifically from POMC neurons resulted in decreased hypothalamic Pomc expression, increased daily food intake, enhanced glucose sensitivity and mild obesity in male but not in female mice. Finally, conditional removal of Six3 from POMC neurons in adult mice led to a reduction in hypothalamic POMC immunoreactivity with no significant effects in body weight or food intake., Conclusions: Altogether, our results demonstrate that Six3 plays an essential role in the early establishment of POMC neuron identity and the maintenance of physiological levels of hypothalamic Pomc expression. In addition, our study demonstrates that the functional significance of Six3 expression in POMC neurons is sexually dimorphic and age-dependent., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

The present study assessed the diet characteristics, trophic guild structure, and microplastics (MPs) ingestion by a group of fish sourced from the tidal creeks of the Mumbai coast along the Eastern Arabian Sea. The diet patterns were characterized using gastro-somatic index (GaSI), relative length of gut (RGL), diet overlap (α), diet breadth (B i ), and relative abundance of food items (%IOP), with a special emphasis on MPs contamination. The findings revealed that teleost and shrimps are the most preferred food items for these species. Whereas MPs contribute 5.50% of the total diet composition of the selected fishes. Additionally, we tried to find out the influence of fish size and dietary attributes on MP ingestion, identifying trophic level as a significant factor influencing contamination levels. Using the Polymer Hazard Index (PHI), the potential risks posed by MPs in fish samples were assessed, revealing notable discrepancies among polymers. For instance, polyvinyl chloride showed the highest PHI score of 198.75 and a hazard score reaching the highest risk category (IV), indicating substantial environmental risk. In summary, our findings highlight the impact of fish diet characteristics on MPs contamination and the varying levels of MP risks along the Mumbai coast, categorized according to polymer type from low to high risk., Competing Interests: Declaration of Competing interest The authors declare no competing interests., (Copyright © 2024 Elsevier Ltd.

Objectives: A healthy diet is essential for preventing chronic disease and promoting overall health. Translating one's intention to eat healthy into actual behaviour has, however, proven difficult with a range of internal and contextual factors identified as driving eating behaviour., Design: We leverage Temporal Self-Regulation Theory to examine these momentary determinants' direct and moderating effects on the intention-behaviour relation with Ecological Momentary Assessment (EMA)., Methods: Eighty-seven healthy participants (m age  = 24.1 years; 59 women, 28 men) reported, 5 times daily for 10 weekdays, their intentions to stick to a self-set dietary restriction goal for the next 3 hr, the goal congruency of their eating behaviour in the past 3 hr, and a range of factors potentially influencing food intake, such as stress, emotions and environmental eating cues., Results: Two-part multilevel modelling revealed that craving, availability of goal-incongruent foods, social eating cues, giving in to other temptations and weaker momentary intentions directly increased the risk and severity of goal-incongruent intake within the next 3 hr. Social cues, stress and craving further influence behaviour through altering intention implementation., Conclusions: Results imply that people regularly fail to implement intentions for 3-hr periods and that a range of factors influences this, both directly and by disrupting intentional processes. While for some barriers, fostering strong intentions throughout the day could be beneficial, others require different strategies for dietary adherence., (© 2024 The Authors.

Background: C-reactive protein (CRP) is a moderately heritable marker of systemic inflammation that is associated with adverse physical and mental health outcomes. Identifying factors associated with genetic liability to elevated CRP in childhood may inform our understanding of variability in CRP that could be targeted to prevent and/or delay the onset of related health outcomes., Methods: We conducted a phenome-wide association study (PheWAS) of genetic risk for elevated CRP (i.e. CRP polygenic risk score [PRS]) among children genetically similar to European ancestry reference populations (median analytic n = 5,509) from the Adolescent Brain and Cognitive Development ℠ (ABCD) Study. Associations between CRP PRS and 2,377 psychosocial and neuroimaging phenotypes were estimated using independent mixed effects models. Post hoc analyses examined whether: (1) covarying for measured body mass index (BMI) or removing the shared genetic architecture between CRP and BMI altered phenotypic associations, (2) sex moderated CRP PRS associations, and (3) associations are unconfounded by assortative mating or passive gene-environment correlations (using a within-family analyses). Multiple testing was adjusted for using Bonferroni and false discovery rate (FDR) correction., Results: Nine phenotypes were positively associated with CRP PRS after multiple testing correction: five weight- and eating-related phenotypes (e.g. BMI, overeating), three phenotypes related to caregiver somatic problems (e.g. caregiver somatic complaints), as well as weekday video watching (all p s = 1.2 × 10 -7 - 2.5 × 10 -4 , all p FDR s = 0.0002 - 0.05). No neuroimaging phenotypes were associated with CRP PRS (all p s = 0.08 - 0.998) after correction for multiple testing. Eating and weight-related phenotypes remained associated with CRP PRS in within-family analyses. Covarying for BMI resulted in largely consistent results, and sex did not moderate any CRP PRS associations. Removing the shared genetic variance between CRP and BMI attenuated all relationships; associations with weekday video watching, caregiver somatic problems and caregiver report that the child is overweight remained significant while associations with waist circumference, weight, and caregiver report that child overeats did not.p FDR s = 0.08 - 0.998) after correction for multiple testing. Eating and weight-related phenotypes remained associated with CRP PRS in within-family analyses. Covarying for BMI resulted in largely consistent results, and sex did not moderate any CRP PRS associations. Removing the shared genetic variance between CRP and BMI attenuated all relationships; associations with weekday video watching, caregiver somatic problems and caregiver report that the child is overweight remained significant while associations with waist circumference, weight, and caregiver report that child overeats did not., Discussion: Genetic liability to elevated CRP is associated with higher weight, eating, and weekday video watching during childhood as well as caregiver somatic problems. These associations were consistent with direct genetic effects (i.e., not solely due to confounding factors like passive gene-environment correlations) and were independent of measured BMI. The majority of associations with weight and eating phenotypes were attributable to shared genetic architecture between BMI and inflammation. The relationship between genetics and heightened inflammation in later life may be partially attributable to modifiable behaviors (e.g. weight and activity levels) that are expressed as early as childhood.

Background: Obesity causes many physical and mental illnesses. This study compares mindfulness-based eating awareness training (MB-EAT) versus MB-EAT plus implementation intention model for effectiveness on body mass index (BMI), weight self-efficacy, and physical activity in obese women with BMIs ≤ 25 (n = 52)., Methods: In this randomized clinical trial, the participants were selected by the simple random sampling method and randomly divided into three groups. A 12-session MB-EAT of 150 min per session was performed for experimental group I. The experimental group II received MB-EAT alone for physical activity planning and MB-EAT plus implementation intention; also, both groups were compared to the control group. Data were measured by the scales, a questionnaire, and a checklist, and the P-values are based on the results of the generalized estimating equation (GEE) test. P < 0.001 were considered the significance level., Results: The MB-EAT and MB-EAT + implementation intention effectiveness on the two experimental groups' BMI, weight self-efficacy, and physical activity was significantly different from the control group. In the integrated group versus the MB-EAT group, BMI, physical activity, and physical discomfort, were more effective than the weight self-efficacy subscales. Both intervention groups were effective on BMI, weight self-efficacy, and physical activity, but the integrated group's effectiveness was more., Conclusions: The MB-EAT effectiveness trial is theory-based, reducing weight and the psychological and behavioral consequences of overweight and obese adults. The MB-EAT + the Implementation intention model is to plan regular and daily exercise according to each individual's specific circumstances., Trial Registration: The trial registration number: (IRCT20200919048767N1)., (© 2024.

Poor diet is a major risk factor for non-communicable disease. The aims of this study were to describe temporal patterns and seasonal changes in diet across the year in Australian adults. A total of 375 adults from a prospective cohort study conducted between 1 December 2019 and 31 December 2021 in Adelaide, Australia, were asked to complete the Dietary Questionnaire for Epidemiological Studies at eight timepoints over a year. Average intakes over the previous month of total energy, macronutrients, healthy food groups, and discretionary foods and beverages were derived. Temporal patterns in diet were analysed descriptively. Multilevel linear regression modelling was used to assess seasonal differences in diet. Of the 375 participants recruited, 358 provided sufficient data for analysis. Intake of total energy, all macronutrients, and most discretionary foods and beverages peaked in December. Total energy intake was higher in summer than in autumn, winter, and spring. Fruit intake was higher in summer than in winter. Consumption of alcoholic beverages was higher in summer than in autumn, winter, and spring. Consumption of non-alcoholic beverages was higher in summer than in autumn and winter. This study identified temporal differences in dietary intake among Australian adults. Seasonal effects appear to be driven largely by increases in consumption of foods and beverages over the December (summer) holiday period. These findings can inform the design and timing of dietary interventions.

Background:  Physicians often focus on possible cardiac causes in patients presenting with chest pain. However, this case highlights a patient who presented with chest pain caused by ingestion of a foreign body after an uneventful meal eaten an hour prior to presentation. The fishbone was discovered after imaging. The article aims to raise awareness regarding the potential origins of chest pain, highlighting that it may stem from non-cardiac conditions., Methods:  The methodology employed in this study involved conducting a case study that meticulously examined the repercussions and management strategies associated with foreign body ingestion., Results:  The case report delineates the scenario of a 27-year-old male patient who inadvertently ingested a fishbone during a routine meal. It details the swift decline in clinical status, the meticulous diagnostic procedures employed, the subsequent management strategies implemented and the ultimate discharge of the patient in a stable condition., Conclusion:  This case highlights the importance of comprehensive history taking and considering a wide range of causes of chest pain when evaluating a patient. The foreign body ingested with the resulting cardiac complications could have been fatal if not promptly diagnosed.Contribution: This study contributed to advancing awareness surrounding foreign body ingestion, shedding light on potential complications and offering valuable insights into effective management strategies.

Background and Aims: Cognitive control and reward-related abnormalities are centrally implicated in addiction. However, findings from longitudinal studies addressing neurocognitive predictors of addictive behaviors are mixed. Further, little work has been conducted predicting non-substance-related addictive behaviors. Our study aimed to assess predictors of substance and non-substance addictive behaviors in a community sample, systematically evaluating each neurocognitive function's independent influence on addictive behavior., Methods: Australians (N = 294; 51.7% female; M[SD] age = 24.8[4.7] years) completed online neurocognitive tasks and surveys at baseline and 3-month follow-up. Self-report scales assessed problematic alcohol use, addictive eating (AE), problematic pornography use (PPU), and problematic internet use (PUI) at 3- and 6-month follow-ups. Linear regressions with bootstrapping assessed neurocognitive predictors for each addictive behavior across a 6-month period., Results: Neurocognition at baseline did not predict AE or PUI severity at 6-month follow-up. Less delay discounting at baseline predicted higher PPU at 6-month follow-up (β = -0.16, p = 0.005). Poorer performance monitoring at baseline predicted higher AE at 3-month follow-up (β = -0.16, p = 0.004), and more reward-related attentional capture at 3-months predicted higher AE at 6-month follow-up (β = 0.14, p = 0.033). Less reward-related attentional capture (β = -0.14, p = 0.003) and less risk-taking under ambiguity (β = -0.11, p = 0.029) at baseline predicted higher PUI at 3-month follow-up. All findings were of small effect size. None of the neurocognitive variables predicted problematic alcohol use., Discussion and Conclusions: We were unable to identify a core set of specific neurocognitive functions that reliably predict multiple addictive behavior types. However, our findings indicate both cognitive control and reward-related functions predict non-substance addictive behaviors in different ways. Findings suggest that there may be partially distinct neurocognitive mechanisms contributing to addiction depending on the specific addictive behavior.

Background: This is an updated and expanded version of the original Cochrane review, first published in 2014. Postoperative oral intake is traditionally withheld after major abdominal gynaecologic surgery until the return of bowel function. The concern is that early oral intake will result in vomiting and severe paralytic ileus, with subsequent aspiration pneumonia, wound dehiscence, and anastomotic leakage. However, clinical studies suggest that there may be benefits from early postoperative oral intake. Currently, gynaecologic surgery can be performed through various routes: open abdominal, vaginal, laparoscopic, robotic, or a combination. In this version, we included women undergoing major gynaecologic surgery through all of these routes, either alone or in combination., Objectives: To assess the effects of early versus delayed (traditional) initiation of oral intake of food and fluids after major gynaecologic surgery., Search Methods: On 13 June 2023, we searched the Cochrane Gynaecology and Fertility Group's Specialised Register, CENTRAL, MEDLINE, Embase, the citation lists of relevant publications, and two trial registries. We also contacted experts in the field for any additional studies., Selection Criteria: We included randomised controlled trials (RCTs) that compared the effect of early versus delayed initiation of oral intake of food and fluids after major gynaecologic surgery, performed by abdominal, vaginal, laparoscopic, and robotic approaches. Early feeding was defined as oral intake of fluids or food within 24 hours post-surgery, regardless of the return of bowel function. Delayed feeding was defined as oral intake after 24 hours post-surgery, and only after signs of postoperative ileus resolution. Primary outcomes were: postoperative ileus, nausea, vomiting, cramping, abdominal pain, bloating, abdominal distension, need for postoperative nasogastric tube, time to the presence of bowel sounds, time to the first passage of flatus, time to the first passage of stool, time to the start of a regular diet, and length of postoperative hospital stay. Secondary outcomes were: infectious complications, wound complications, deep venous thrombosis, urinary tract infection, pneumonia, satisfaction, and quality of life., Data Collection and Analysis: Two review authors independently selected studies, assessed the risk of bias, and extracted the data. We calculated the risk ratio (RR) with a 95% confidence interval (CI) for dichotomous data. We examined continuous data using the mean difference (MD) and a 95% CI. We tested for heterogeneity between the results of different studies using a forest plot of the meta-analysis, the statistical tests of homogeneity of 2 x 2 tables, and the I² value. We assessed the certainty of the evidence using GRADE methods., Main Results: We included seven randomised controlled trials (RCTs), randomising 902 women. We are uncertain whether early feeding compared to delayed feeding has an effect on postoperative ileus (RR 0.49, 95% CI 0.21 to 1.16; I² = 0%; 4 studies, 418 women; low-certainty evidence). We are uncertain whether early feeding affects nausea or vomiting, or both (RR 0.94, 95% CI 0.66 to 1.33; I² = 67%; random-effects model; 6 studies, 742 women; very low-certainty evidence); nausea (RR 1.24, 95% CI 0.51 to 3.03; I² = 74%; 3 studies, 453 women; low-certainty evidence); vomiting (RR 0.83, 95% CI 0.52 to 1.32; I² = 0%; 4 studies, 559 women; low-certainty evidence), abdominal distension (RR 0.99, 95% CI 0.75 to 1.31; I² = 0%; 4 studies, 559 women; low-certainty evidence); need for postoperative nasogastric tube placement (RR 0.46, 95% CI 0.14 to 1.55; 3 studies, 453 women; low-certainty evidence); or time to the presence of bowel sounds (MD -0.20 days, 95% CI -0.46 to 0.06; I² = 71%; random-effects model; 3 studies, 477 women; low-certainty evidence). There is probably no difference between the two feeding protocols for the onset of flatus (MD -0.11 days, 95% CI -0.23 to 0.02; I² = 9%; 5 studies, 702 women; moderate-certainty evidence). Early feeding probably results in a slight reduction in the time to the first passage of stool (MD -0.18 days, 95% CI -0.33 to -0.04; I² = 0%; 4 studies, 507 women; moderate-certainty evidence), and may lead to a slightly sooner resumption of a solid diet (MD -1.10 days, 95% CI -1.79 to -0.41; I² = 97%; random-effects model; 3 studies, 420 women; low-certainty evidence). Hospital stay may be slightly shorter in the early feeding group (MD -0.66 days, 95% CI -1.17 to -0.15; I² = 77%; random-effects model; 5 studies, 603 women; low-certainty evidence). The effect of the two feeding protocols on febrile morbidity is uncertain (RR 0.96, 95% CI 0.75 to 1.22; I² = 47%; 3 studies, 453 women; low-certainty evidence). However, infectious complications are probably less common in women with early feeding (RR 0.20, 95% CI 0.05 to 0.73; I² = 0%; 2 studies, 183 women; moderate-certainty evidence). There may be no difference between the two feeding protocols for wound complications (RR 0.82, 95% CI 0.50 to 1.35; I² = 0%; 4 studies, 474 women; low-certainty evidence), or pneumonia (RR 0.35, 95% CI 0.07 to 1.73; I² = 0%; 3 studies, 434 women; low-certainty evidence). Two studies measured participant satisfaction and quality of life. One study found satisfaction was probably higher in the early feeding group, while the other study found no difference. Neither study found a significant difference between the groups for quality of life (P > 0.05)., Authors' Conclusions: Despite some uncertainty, there is no evidence to indicate harmful effects of early feeding following major gynaecologic surgery, measured as postoperative ileus, nausea, vomiting, or abdominal distension. The potential benefits of early feeding include a slightly faster initiation of bowel movements, a slightly sooner resumption of a solid diet, a slightly shorter hospital stay, a lower rate of infectious complications, and a higher level of satisfaction., (Copyright © 2024 The Cochrane Collaboration.
