Association between Socioecological Status, Nutrient Intake, and Cancer Screening Behaviors in Adults Aged 40 and Over: Insights from the Eighth Korea National Health and Nutrition Examination Survey (KNHANES, 2019).

Cancer screening is pivotal for early detection and improved survival rates. While socio-ecological factors are known to influence screening uptake, the role of lifestyle, dietary habits, and general health in shaping these decisions remains underexplored. Utilizing the 2019 Korea National Health and Nutrition Examination Survey (KNHANES), this study examined the myriad of factors impacting cancer screening utilization. Data from 274,872 adults aged 40 years or older were scrutinized, highlighting demographics, income, lifestyle behaviors, health-related variables, nutrient intake, and dietary quality. A combination of descriptive statistics and logistic regression helped us ascertain influential determinants. Higher educational attainment and income quartiles were positively correlated with cancer screening rates. Regular walkers, those engaged in moderate physical activity, and individuals with a previous cancer diagnosis were more likely to get screened. High-risk drinkers and smokers were less inclined towards screening. Dietary habits also influenced screening decisions. Notably, participants with healthier eating behaviors, indicated by factors such as regular breakfasts and fewer meals out, were more likely to undergo screening. Additionally, nutrient intake analysis revealed that those who had undergone screening consumed greater quantities of most nutrients, bar a few exceptions. For individuals aged 50-64, nutritional assessment indicators highlighted a higher mean adequacy ratio (MAR) and index of nutritional quality (INQ) value among those who participated in screening, suggesting better nutritional quality. This study elucidates the complex socio-ecological and nutritional landscape influencing cancer screening decisions. The results underscore the importance of a holistic approach, emphasizing lifestyle, dietary habits, and socio-economic considerations. It provides a roadmap for policymakers to craft more inclusive screening programs, ensuring equal access and promoting early detection.

Is Ultra-Processed Food Intake Associated with a Higher Risk of Glaucoma? A Prospective Cohort Study including 19,255 Participants from the SUN Project.

OBJECTIVE: The aim of this study was to examine the relationship of ultra-processed food (UPF) intake with the incidence of glaucoma in a large sample of Spanish university graduates followed prospectively. METHODS: Prospective cohort study using data from the SUN Project. A final sample of 19,225 participants (60.1% women) was included in this study, with a mean age of 38.2 years (standard deviation (SD) = 12.4). Participants were followed-up for a mean time of 12.9 years (SD = 5.4). Dietary intake was measured using a 136-item semiquantitative food-frequency questionnaire. UPFs were defined based on the NOVA classification system. Glaucoma diagnosis was determined by asking the participants if they had ever been diagnosed with glaucoma by an ophthalmologist. This self-reported diagnosis of glaucoma has been previously validated. RESULTS: After adjusting for several covariates, participants with the highest UPF consumption were at higher risk of glaucoma (hazard ratio (HR) = 1.83; 95% confidence interval (CI) 1.06 to 3.17) when compared to participants in the lowest category of UPF consumption. Regarding subgroup analyses, a significant multiplicative interaction was found for age (p = 0.004) and omega 3:6 ratio (p = 0.040). However, an association between UPF consumption and glaucoma was only found in older participants (aged ≥ 55 years), in men, in the most physically active group, in the group of non- or former smokers, in those with a lower omega 3:6 ratio, and in those with a lower energy intake. Regarding the contribution of each type of UPF group, UPF coming from sweets showed a significant risky effect (HR = 1.51; CI 95% 1.07 to 2.12). CONCLUSIONS: This prospective cohort study shows that participants with a greater UPF consumption have a higher risk of developing glaucoma when compared to participants with a lower consumption. Our findings emphasize the relevance of monitoring and limiting the consumption of UPFs as a means of preventing glaucoma incidence.

Chrononutrition in traditional European medicine-Ideal meal timing for cardiometabolic health promotion.

Meal timing plays a crucial role for cardiometabolic health, given the circadian regulation of cardiometabolic function. However, to the best of our knowledge, no concept of meal timing exists in traditional European medicine (TEM). Therefore, in this narrative review, we aim to define the optimal time slot for energy intake and optimal energy distribution throughout the day in a context of TEM and explore further implications. By reviewing literature published between 2002 and 2022, we found that optimal timing for energy intake may be between 06:00 and 09:00, 12:00 and 14:00, and between 15:00 and 18:00, with high energy breakfast, medium energy lunch and low energy dinner and possibly further adjustments according to one's chronotype and genetics. Also, timing and distribution of energy intake may serve as a novel therapeutic strategy to optimize coction, a concept describing digestion and metabolism in TEM.

Longitudinal Relationship between the Percentage of Energy Intake from Macronutrients and Overweight/Obesity among Chinese Adults from 1991 to 2018.

To investigate the prospective relationship between macronutrient intake and overweight/obesity, data were collected in the China Health and Nutrition Survey (CHNS) from 1991 to 2018. Adults who participated in at least two waves of the survey and were not obese at baseline were selected as the study subjects. A total of 14,531 subjects were finally included with complete data. Overweight/obesity was defined as a body mass index (BMI) ≥ 24.0 kg/m2. The generalized estimating equation (GEE) was used to analyze the relationship between the percentage of energy intake from macronutrients and BMI and overweight/obesity. The percentages of energy intake from protein and fat showed an increasing trend (p < 0.01), and the percentage of energy intake from carbohydrate showed a decreasing trend (p < 0.01) among Chinese adults between 1991 and 2018. Adjusting for covariates, the energy intake from fat was positively correlated with BMI, while the energy intake from carbohydrates was negatively correlated with BMI. The percentage of energy intake from non-high-quality protein and polyunsaturated fatty acids (PUFA) were positively correlated with overweight/obesity. In contrast, monounsaturated fatty acids (MUFA) and high-quality carbohydrates were negatively correlated with overweight/obesity. In short, fat, non-high-quality protein, saturated fatty acids (SFA), and PUFA were positively correlated with the risk of obesity, whereas higher carbohydrate, MUFA, and high-quality carbohydrate intake were associated with a lower risk of obesity. Obesity can be effectively prevented by appropriately adjusting the proportion of intake from the three major macronutrients.

Contribution of Infant Food Pouches and Other Commercial Infant Foods to the Diets of Infants: A Cross-sectional Study.

BACKGROUND: Although considerable concern has been expressed about the nutritional implications of infant food pouches, how they impact infant diet has not been examined. OBJECTIVES: The objective of this study was to determine the contribution of infant food pouches specifically, and commercial infant foods generally, to nutrient intake from complementary foods in infants. METHODS: Two multiple-pass 24-h diet recall data were collected from 645 infants (6.0-11.9 mo) in the First Foods and Young Foods New Zealand studies. Detailed information was obtained on commercial infant food use, including pouches, and nutrient composition was calculated through recipe modeling. RESULTS: The diverse sample (46.1% female; 21.1% Maori, 14.1% Asian, and 54.6% European) was aged (SD) 8.4 (0.9) mo. More than one-quarter of households had high socioeconomic deprivation. Almost half (45.3%) of infants consumed an infant food pouch on ≥1 recall day [mean (SD), 1.3 (0.9) times/d], obtaining 218 (124) kJ of energy on each eating occasion. Comparable numbers for all commercial infant and toddler foods (CITFs) were 78.0%, contributing 2.2 (1.6) and 140 (118) kJ of energy. Infant food pouches provided 25.5% of the total energy from complementary foods in those infants who consumed pouches on the recall days but just 11% in all infants. Median percentage contribution of infant food pouches to nutrient intake from complementary foods in consumers ranged from <1% (added sugars and retinol) to >30% (carbohydrate, total sugars, fiber, vitamin A, and vitamin C). CITF contributed 21.4% of energy from complementary foods for infant consumers, with median percentage contribution ranging from 0.1% (retinol) to 40.3% (iron). CONCLUSIONS: Infant food pouches make relatively small contributions to energy intake in infants but are important sources of carbohydrates, fiber, and vitamins A, C, and B-6. Almost half of the total sugars consumed from complementary foods is provided by these pouches. This trial was registered at the Australian New Zealand Clinical Trials Registry as ACTRN12620000459921.

Prevention of Postoperative Malnutrition with Oral Nutritional Supplements in Patients Undergoing Gastrointestinal Surgery.

Oral nutritional supplements (ONSs) offer support for the nutritional needs of surgical patients. However, their efficacy is contingent upon the nutrient composition, absorption efficiency, and postingestion tolerance. Our study included a cohort of 84 patients who underwent elective open surgery involving at least one intestine anastomosis. To mitigate the risk of malnutrition, 2 groups of 28 patients each received either a high-protein low-osmotic ONS (Group I) or a high-calorie high-osmotic ONS (Group II). A standard diet was used in the control group (Group III). The metabolic effects were evaluated by measuring body weight and relative change in body weight (Δkg) from 24 h (-1 day) presurgery to 28 days postprocedure. Subjective tolerance following ONS consumption on the second postoperative day was also assessed. Our findings showed that, across all groups, the average body weight decreased during the initial 2 weeks postsurgery, subsequently stabilizing or returning to baseline levels by the third and fourth week of observation. Patients receiving ONS demonstrated greater weight gain between days 14 and 28, with Group I exhibiting the highest rate of gain. Low-osmotic ONS displayed superior tolerance and elicited fewer patient complaints postconsumption. Postoperative hospitalization duration did not differ significantly among the nutritional strategies. In conclusion, early administration of ONS supplies essential nutrients and facilitates refeeding, thereby reducing the risk of malnutrition. Low-osmotic preparations are better tolerated and contribute more effectively to the restoration of preoperative body weight, despite their lower caloric content.

Nutritional status changes in the treatment of substance use disorder: Relationship with substance craving.

Tailored nutrition counseling enhances the efficacy of routine treatment for substance (alcohol/drugs) use disorders (SUDs). For this purpose, it is important to understand the current nutritional status of addicts and the changes in their nutritional status during the treatment process. Furthermore, the consumption of sweets to manage substance cravings is common among people with SUDs, but the evidence for the effectiveness of this practice is limited and conflicting. We therefore hypothesized SUD treatment would be associated with increases in appetite, nutrient intake, and anthropometric measurements in addicts, and that these changes, including changes in sweet consumption, would not be associated with decreased substance craving. Data for this prospective observational study were collected from 38 adult male patients who completed 21 days of inpatient SUD treatment. During the treatment, the participants' levels of appetite (P < 1.0 × 10-4), the frequency of main meals (P < 1.0 × 10-4), intake of macro- and micronutrients (P < .05 for each), and anthropometric measurements (P ≤ 5.9 × 10-4), significantly increased. Furthermore, it was found that the patients had a significant increase in sweets craving (P < 1.0 × 10-4) and sweets consumption (P = 1.2 × 10-3) during treatment. However, there was no significant difference between the individuals whose craving decreased and those whose craving did not decrease at the end of the treatment (P > .05 for both). The findings suggest the need to offer dietary counseling to individuals undergoing inpatient SUD treatment, given the substantial changes in nutritional status, and that increased consumption of sweets is not an effective strategy to reduce substance craving.

The influence of patients' nutritional risk, nutritional status, and energy density in MEDPass versus conventional administration of oral nutritional supplements - A secondary analysis of a randomized controlled trial.

OBJECTIVES: The clinical influence of nutritional risk, nutritional status, and energy density of oral nutritional supplements (ONS) in MEDPass versus conventional administration of ONS is currently unknown. The aim of this analysis was to examine whether these variables have an impact on clinical outcomes. METHODS: Secondary analysis of the intention to treat dataset of the randomized controlled MEDPass Trial in geriatric and medical inpatients. Patients in the intervention group received 4 × 50 ml ONS during the medication rounds (MEDPass mode), while those in the control group received ONS in a non-standardized manner. The examined endpoints included energy and protein coverage, ONS intake, handgrip strength (HGS), weight, appetite nausea and 30-day mortality. Three subgroup analyses for NRS 2002 total score (3, 4 or 5-7 points), NRS 2002 impaired nutritional status score (0, 1, 2 or 3 points) and energy density of the ONS (1.5 kcal/mL or 2 kcal/mL) were performed using linear and logistic regression with interaction and mixed effect models. RESULTS: The data of 202 patients (103 women and 99 men) at nutritional risk (NRS total 2002 score ≥3), mean (SD) age 82.2 (6.5) years were included. There was no significant difference between the groups in the primary endpoint energy coverage in all three subgroup analyses. There were also no significant differences between the groups in the secondary endpoints of protein coverage, ONS intake, HGS, weight, appetite, nausea, and 30-day mortality. CONCLUSION: The MEDPass mode of ONS administration was not superior to the conventional mode of administration in this study. ONS with high energy density (≥2 kcal/mL) should be offered since current evidence shows a tendency towards improved appetite, increased ONS and increased energy intake.

Assessment of Nutritional Composition of Turkish Red Crescent Menus After the M7.8 and M7.6 Earthquakes in Kahramanmaras, Türkiye.

OBJECTIVE: This study aims to evaluate the nutritional content and quality of the Turkish Red Crescent (TRC) menus delivered to earthquake victims after the 2023 earthquakes in Kahramanmaras, Türkiye. METHODS: The menus of general, search-rescue, diabetes, and celiac were obtained from the TRC following the magnitudes of 7.8 and 7.6 Kahramanmaras earthquakes. The nutrient content of the menus was evaluated with the Nutrient Rich Food (NRF20.3) score. In addition, the menus' energy, macronutrient, and micronutrient contents were compared with the dietary reference intake values of the Türkiye Dietary Guideline-2022, European Food Safety Authority, and Food and Drug Administration. RESULTS: The general menu was insufficient to meet the daily requirements of vitamin D, vitamin K, vitamin C, calcium, and potassium for earthquake victims. The sodium, phosphorous, and omega-6/omega-3 ratios were much higher than the recommended intakes. The NRF20.3 score of the diabetes menu was significantly higher than the search-rescue and celiac menus (P < 0.05). The energy content of the search-rescue menu was significantly higher than that of other menus (P < 0.05). CONCLUSION: The several nutritional risks were determined in TRC menus for earthquake victims who suffered from the Kahramanmaras earthquakes. Several supplementation programs can be applied to the earthquake regions to obtain strength immunity and effectively challenge posttraumatic stress symptoms.

Nutrient intake, productive and metabolic parameters of Nellore bulls feed a forage free diet using cottonseed cake as a fiber source.

We hypothesized that cottonseed cake in confined Nellore young bulls' diet as fiber source, could maintain or improve the nutrient intake, and productive and metabolic parameters. It was evaluated the total replacement of whole plant corn silage (WPCS) by cottonseed cake (CSC) as a source of fiber in the diet. A completely randomized design with two treatments and 12 replications was used. The treatments were two experimental diets containing 300 g/kg of WPCS or CSC as roughage. All animals at 0, 15, 30, 60 and 112 days were weighed to monitor productive performance and nutrient intake. Dry matter intakes, organic matter, neutral detergent fiber, physically effective neutral detergent fiber, crude protein and non-fiber carbohydrates of the WPCS treatment cattle were higher (p < 0.05), and the ethereal extract intake of cattle fed CSC diet was higher. The BW of cattle fed WPCS was higher in the two initial periods of confinement (p < 0.05). Animals from both treatments showed linear growth during the confinement period. There was a fiber source × period interaction for total weight gain (TWG), average daily gain (ADG) and feed efficiency (FE) (p < 0.05), with the lowest in the first 15 days and the highest at 30 days, reflecting a compensatory gain in animals fed with CSC. Bulls fed with CSC showed negative TWG and ADG in the first period (p < 0.05), but recovered in the following periods, surpassing that of the SC treatment in the last two periods. There was negative EF of bulls fed with CSC in the first period (P < 0.05), but in the following periods the CSC diet did not differ from the WPCS diet. The animals fed CSC diet showed a higher concentration of cholesterol and glucose in the blood plasma (p < 0.05). The forage-free diet containing cottonseed cake as a source of fiber replacing corn silage promoted better animal performance.

Individualised nutritional treatment increases the positive effects of a novel á la carte hospital food service concept: Results of a quasi-experimental study.

BACKGROUND & AIMS: One-third of hospitalised patients are at nutritional risk, and limited choice regarding meals and meal times, and inadequate nutritional support may contribute to inadequate nutritional intake during hospitalisation. The aim was to test the effect of a novel á la carte hospital food service concept as a stand-alone intervention and combined with individualised nutritional treatment. METHODS: Medical inpatients at nutritional risk were recruited for this three-arm quasi-experimental study. The control group received meals from the traditional bulk trolley food service system. Intervention group 1 (IG1) received meals from a novel á la carte food service concept with an electronic ordering system, whereas intervention group 2 (IG2) in addition to this received individualised nutritional treatment by a clinical dietitian. Nutritional intake and length of stay was measured, and patient satisfaction was assessed with purpose-designed questionnaires. RESULTS: 206 patients were included: 67 in the control group, 68 in IG1, and 71 in IG2. The proportion of participants reaching ≥75 % of both their energy and protein requirement was higher in IG1 compared to the control group (34 % vs. 12 %, p = 0.002) and higher in IG2 compared to IG1 (53 % vs. 34 %, p = 0.035). Length of stay was shorter in IG2 compared to the control group (6.0 vs. 8.7 days, p = 0.005). It was important to participants to be able to choose when and what to eat, and this preference was met to a larger extent in the intervention groups. CONCLUSION: The novel á la carte concept increases energy and protein intake in hospitalised patients, and the positive effects are increased, when the concept is used in combination with individualised nutritional treatment.

Effects of physical form of ß-lactoglobulin and calcium ingestion on GLP-1 secretion, gastric emptying and energy intake in humans: a randomised crossover trial.

The aim of this study was to assess whether adding Ca2+ to aggregate or native forms of ß-lactoglobulin alters gut hormone secretion, gastric emptying rates and energy intake in healthy men and women. Fifteen healthy adults (mean ± sd: 9M/6F, age: 24 ± 5 years) completed four trials in a randomised, double-blind, crossover design. Participants consumed test drinks consisting of 30 g of ß-lactoglobulin in a native form with (NATIVE + MINERALS) and without (NATIVE) a Ca2+-rich mineral supplement and in an aggregated form both with (AGGREG + MINERALS) and without the mineral supplement (AGGREG). Arterialised blood was sampled for 120 min postprandially to determine gut hormone concentrations. Gastric emptying was determined using 13C-acetate and 13C-octanoate, and energy intake was assessed with an ad libitum meal at 120 min. A protein × mineral interaction effect was observed for total glucagon-like peptide-1 (GLP-1TOTAL) incremental AUC (iAUC; P < 0·01), whereby MINERALS + AGGREG increased GLP-1TOTAL iAUC to a greater extent than AGGREG (1882 ± 603 v. 1550 ± 456 pmol·l-1·120 min, P < 0·01), but MINERALS + NATIVE did not meaningfully alter the GLP-1 iAUC compared with NATIVE (1669 ± 547 v. 1844 ± 550 pmol·l-1·120 min, P = 0·09). A protein × minerals interaction effect was also observed for gastric emptying half-life (P < 0·01) whereby MINERALS + NATIVE increased gastric emptying half-life compared with NATIVE (83 ± 14 v. 71 ± 8 min, P < 0·01), whereas no meaningful differences were observed between MINERALS + AGGREG v. AGGREG (P = 0·70). These did not result in any meaningful changes in energy intake (protein × minerals interaction, P = 0·06). These data suggest that the potential for Ca2+ to stimulate GLP-1 secretion at moderate protein doses may depend on protein form. This study was registered at clinicaltrials.gov (NCT04659902).

Estimated energy and nutrient intake in complementary feeding methods in Brazilian infants: randomized clinical trial.

Inadequate nutrient intake during complementary feeding (CF) can affect healthy infant growth and development. A randomized clinical trial was conducted to examine the energy and nutrient intake in Brazilian children randomly assigned to three distinct CF methods. Mother-infant pairs participated in the study, with mothers receiving interventions in one of three CF approaches: (A) strict Parent-Led Weaning (PLW); (B) strict Baby-Led Introduction to Solids (BLISS); and (C) a mixed method. Assessments were made at 5.5 months, nine months, and 12 months of the child's age. Food consumption was measured through 24-h dietary recalls at nine and 12 months, with intake estimates calculated using the Brazilian Food Composition Table. Means or medians of energy and nutrients were compared between groups using ANOVA with Tukey's post hoc test or the Kruskal-Wallis test. A total of 115 infants were evaluated at nine months, and 102 at 12 months. Children in the PLW, BLISS, and mixed method groups exhibited comparable dietary intakes of energy, macronutrients, and micronutrients at both nine and 12 months. Infants following PLW, BLISS, and mixed methods demonstrated similar levels of energy and nutrient intake, underscoring the effectiveness of these strategies in ensuring comparable nutrient intake during the critical phase of CF.Trial registration The trial was registered in the Brazilian Registry of Clinical Trials (ReBEC) with identifier [RBR-229scm U1111-1226-9516], [ https://ensaiosclinicos.gov.br/rg/RBR-229scm ]. The full data of the first registration was on 24/09/2019.

Food sources of fiber and micronutrients of concern among infants and young children in Lebanon: a national cross-sectional study.

BACKGROUND: Intakes of fiber, iron, zinc, calcium, vitamin D, vitamin A, and folate were shown to be low in a substantial proportion of infants and children in Lebanon. The study aims to identify the top food sources of fiber, iron, zinc, calcium, vitamin D, vitamin A, and folate amongst infants and young children in Lebanon and to evaluate the evolution of food sources of these nutrients from the beginning of the complementary feeding journey up until the age of 47.9 months. METHODS: A national cross-sectional survey was conducted in 2012 as part of the "Early Life Nutrition and Health in Lebanon" project using stratified cluster sampling. Dietary intakes for infants and young children aged 6-47.9 months (n = 763) were assessed using 24- Hour Dietary Recall. Food items were categorized into food groups and the percent contribution of each food group to nutrient intakes was determined to identify the top food sources of fiber and selected micronutrients for three age groups: 6-11.9 m (infants), 12-23.9 m (toddlers), and 24-47.9 m (preschoolers). RESULTS: The top food source of fiber was vegetables among children aged 6-47.9 months. Among infants and toddlers, infant/young child formula was the main contributor to iron, zinc, calcium, vitamin D, vitamin A, and folate intakes. Baby cereals also contributed to around 14% of iron intakes among infants. Among preschoolers, meat and fish contributed to 13% of iron intakes and 29% of zinc intakes, while cow's milk was the major contributor of calcium (41%), vitamin D (81%) and vitamin A (25%) intakes. Sweetened beverages and sweet bakery were also ranked among the major food sources contributing to substantial intakes of key nutrients, including fiber, iron, zinc, calcium, vitamin A, and folate among infants, toddlers, and preschoolers. CONCLUSIONS: In addition to milk sources, vegetables, beans and legumes, breads, meats, and rice and pasta, sweet bakery and sweetened beverages have contributed to intakes of key nutrients from early ages. This calls for implementing initiatives and designing approaches to support nutrition education and improve nutrient intakes in infancy and early childhood.

Current Guidelines on Fat Intake in Pregnant and Lactating Women, Infants, Children, and Adolescents: A Scoping Review.

INTRODUCTION: Dietary fat intake in pregnancy, lactation, and childhood determines child growth, neurodevelopment, and long-term health. METHODS: We performed a scoping review of dietary guidelines on fat intake for pregnant and lactating women, infants, children, and adolescents. We systematically searched several databases and websites for relevant documents published in English from 2015 to 2019. RESULTS: We included 14 documents. Of those, eight targeted pregnant and/or lactating women, mainly recommending daily intake of approx. 250 mg/d of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), while one advised supplementing 800 mg/d DHA and 100 mg/d EPA in women of low omega-3 fatty acid status. The number of guidelines for infants was low (n = 3). Recommended intakes of total fat were 30-40% and 20-35% of total energy intake (TEI) for infants and children, respectively. Intakes of saturated fatty acids (SFAs) <10% of TEI and avoidance of trans-fatty acids (TFAs) were recommended across childhood. The methodology applied to develop guidelines and to grade the strength of recommendations was heterogeneous. CONCLUSION: Quantitative recommendations on fat intake during pregnancy focused mainly on PUFA intake, and those targeting infants were limited. Consistent recommendations were provided for total fat, SFA, and TFA intake in childhood; however, strength of recommendation was mostly not reported.

Effect of monensin on milk production efficiency and milk composition in lactating dairy cows fed modern diets.

Since the US Food and Drug Administration's approval of monensin in 2004, significant nutritional advances have been made to increase feed efficiency and milk fat production. Recent evidence suggests monensin's adverse effect on milk fat percentage may be absent when diets are formulated to address known diet-induced milk fat depression risk factors. Thus, study objectives were to evaluate effects of monensin level on dry matter intake (DMI), milk production and composition, and efficiency of high-producing cows fed diets formulated to optimize milk fat. Ninety-six lactating Holstein cows (36 primiparous, 60 multiparous; 106 ± 17 d in milk [DIM]) were balanced by parity, DIM, and milk production and were randomly assigned to 1 of 12 pens with 8 cows per pen. All cows received 11 g/t monensin for 5 wk after which pens received 1 of 4 dietary treatments (n = 3) formulated to provide 0 (CON), 11 (R11), 14.5 (R14.5), or 18 (R18) g/t monensin for 9 wk. The basal diet was 54% forage, 27% NDF, 29% starch, and 2.3% rumen unsaturated fatty acid load. Pen was the experimental unit and data were analyzed using the Fit Model Procedure of JMP. Effects of treatment, time, and treatment × time interaction were included as fixed effects and pen as a random effect. Least squares means were determined and linear and quadratic contrasts were tested. Dry matter intake tended to decrease linearly with increasing monensin dose. Milk yield, fat percentage, and protein percentage and yield were unaffected by treatment while fat yield was quadratically increased. Milk de novo and mixed fatty acid (FA) yields (g/d) increased quadratically with monensin whereas preformed FA linearly decreased during the experimental period. Energy-corrected milk (ECM) was quadratically increased by monensin. Milk urea nitrogen concentrations increased linearly with increasing monensin dose. Monensin linearly increased feed efficiency (ECM/DMI, 3.5% fat-corrected milk/DMI, and solids-corrected milk/DMI). Body weight gain did not differ between treatments. Estimated dietary energy tended to increase linearly with increasing monensin level. These data suggest monensin improves component-corrected milk production efficiency, estimated dietary energy, and does not negatively affect milk fat percentage or FA profile.

Proinflammatory Dietary Intake Relates to Pain Sensitivity in Chronic Nonspecific Low Back Pain: A Case-Control Study.

Nonspecific chronic low back pain (nCLBP) has been associated with nutrition. Yet, it is not clear how nutritional factors and nCLBP relate to one another. Therefore, the aim of the present study was to investigate differences in diet quality and dietary intake levels between nCLBP patients and healthy controls (HCs) and explore the association between nutritional factors and pain sensitivity in nCLBP. In this case-control study, 106 participants (ie, n = 53 nCLBP and n = 53 HCs) were recruited and completed a 3-day food diary to assess their dietary intake, which allowed to generate individual diet quality scores (ie, the Healthy Eating Index-2015 and Dietary Inflammatory Index). Additionally, each participant underwent an experimental pain assessment (quantitative sensory testing) and filled out self-reported pain questionnaires. Compared to HCs, the nCLBP group showed significantly lower diet quality, higher inflammatory scores, and a lower intake of total protein, total fat, dietary fiber, omega-3 fatty acids, vitamin B6, vitamin A, beta-carotene, vitamin E, and magnesium. Pain sensitivity mainly showed a negative correlation with nutritional intakes known for anti-inflammatory properties (ie, vitamins E, D, A, B6, B12, and zinc). Interestingly, total fat, cholesterol, saturated, and monounsaturated fat intakes were found to be inversely associated with pain sensitivity. Overall, patients with nCLBP have a lower diet quality, eat more proinflammatory, have less intake of nutrients known for their anti-inflammatory and antioxidative properties, and drink less water compared to HCs. Accordingly, pain sensitivity was mainly found to be positively associated with proinflammatory dietary intake. PERSPECTIVE: This study emphasizes the association between a proinflammatory diet and nCLBP. Among nCLBP patients, positive association between increased pain sensitivity and the proinflammatory potential of a diet, highlighting the potential for individualized pain management strategies and leading to the development of novel therapeutic methods.

It is not just about prescription. A cohort study of the impact of enteral nutrition on mortality of hospitalized patients with COVID-19.

Introduction: Introduction: during COVID-19 pandemic, international societies released guidelines and recommendations for patients requiring nutritional support according to previous similar respiratory diseases. Objectives: the aim of the study was to evaluate the nutritional support provided by enteral nutrition (EN) in patients with COVID-19 infection, identify if the recommendations from international societies were met and their impact on mortality rate. Methods: a cohort study was conducted on adult patients with COVID-19 admitted to a tertiary hospital. Demographic, clinical, biochemical, and nutritional variables were obtained. A random-effect parametric survival-time model was performed to quantify the risk of death for each variable, and the Hausman test was used to confirm the model. Results: two hundred and twenty-nine patients were enrolled. The delivered energy was > 80 % of adequacy in the first two days, as suggested by international guidelines (11.7 ± 4.9 kcal/kg); however, an adequacy rate less than 60 % was achieved on day 14 (25.4 ± 7.4 kcal/kg). The protein adequacy was > 75 % on the first days of infusion (1.3 ± 0.3 g/kg); however, the infusion was < 50 % (1.5 ± 0.4 g/kg) after being extubated. Age, sex, and nutritional risk were related to higher mortality in patients with EN, whereas the infused energy and protein, the percentage of protein adequacy, arginine, and n-3 PUFA were associated with lower mortality. Conclusion: achieving at least 80 % of the energy and protein requirements, as well as n-3 PUFA and arginine supplementation could be associated with lower mortality in COVID-19 patients. More studies are needed to confirm the role of these nutrients on the mortality rate.

Introducción: Introducción: durante la pandemia de COVID-19, las sociedades internacionales publicaron guías y recomendaciones para pacientes que requieren apoyo nutricional basándose en lo previamente recomendado en enfermedades respiratorias similares. Objetivos: evaluar el soporte nutricional con nutrición enteral (NE) en pacientes con COVID-19 e identificar el cumplimiento de las recomendaciones hechas por las sociedades internacionales y su impacto en la tasa de mortalidad. Métodos: estudio de cohorte en adultos con COVID-19 ingresados en un hospital de tercer nivel. Se registraron variables demográficas, clínicas, bioquímicas y nutricionales. Se realizó un modelo de supervivencia de efectos aleatorios para cuantificar el riesgo de muerte para cada variable y la prueba de Hausman para confirmar el modelo. Resultados: se incluyeron 229 pacientes. La energía administrada fue > 80 % de adecuación en los dos primeros días (11,7 ± 4,9 kcal/kg); sin embargo, fue < 60 % el día 14 (25,4 ± 7,4 kcal/kg). La adecuación de proteínas fue > 75 % en los primeros días de infusión (1,3 ± 0,3 g/kg), pero < 50 % (1,5 ± 0,4 g/kg) después de ser extubado. La edad, el sexo y el riesgo nutricional se relacionaron con mayor mortalidad, mientras que la energía y proteína infundidas, el porcentaje de adecuación proteica, la arginina y el contenido de ácidos grasos poliinsaturados (AGPI) n-3 se asociaron con menor mortalidad. Conclusión: aunque se necesitan más estudios para confirmarlo, alcanzar al menos el 80 % de los requerimientos energéticos y proteicos, así como la suplementación de fórmulas con AGPI n-3 y arginina, podría asociarse con menor mortalidad en pacientes con COVID-19.

Energy, protein and iron densities of dabi teff-field pea-based optimised novel complementary flour and its contribution to daily energy and nutrients demand by 6-23-month-old children.

Inadequate intake of age-specific energy and nutrients is among the prime immediate causes of child malnutrition. Thus, this study aimed to determine the energy, protein and Fe densities of pre-processed dabi teff-field pea-based optimised novel complementary flour and its contribution to daily energy and nutrients demand by 6-8, 9-11 and 12-23 month-old children. The optimal formula at overall optimisation was identified to be 34·66 % dabi teff, 25 % barley, 15 % oats, 15·34 % field pea, 5 % linseed and 5 % maize with response values of 15·74 % protein, 5·09 % fat, 2·26 % ash, 2·88 % fibre, 73·05 % carbohydrate, 1591·72 kJ/100 g (380·43 kcal/100 g) energy, 32·21 mg/100 g Fe, 77·51 mg/100 g Ca and 2·59 mg/100 g Zn. The energy density of the optimised novel complementary flour was 1·27 kcal/g which fulfilled the Pan American Health Organization/WHO recommendation (≥ 0·8 kcal/g), protein density was 4·14 g/100 kcal and the Fe density was 8·47 mg/100 kcal, which was 2·12 to 10·59 times higher than the recommended value where the optimal had demonstrated to contribute more than 100 % of the daily energy and protein demand and notably more than 200 % of daily Fe demand at moderate bioavailability (0·8-4 mg/100 kcal). These findings showed that the daily recommended dietary allowance for energy, protein and Fe could be attained by the developed dabi teff-field pea-based optimised novel complementary flour and its contribution to the children's daily energy and nutrients demand met the standard, where the product can be used as food-based nutrition intervention to manage protein-energy malnutrition and Fe deficiency anemia in children sustainably.

Food pattern modeling to inform global guidance on complementary feeding of infants.

Nutrient needs are difficult to meet during infancy due to high nutrient requirements and the small quantities of food consumed. Guidelines to support food choice decisions are critical to promoting optimal infant health, growth and development and food pattern modeling can be used to inform guideline development. We employed the Optifood modeling system to determine if unfortified complementary foods could meet 13 nutrient targets for breastfed infants (6-11 months), and to describe food patterns that met, or came as close as possible to meeting targets. We also examined the impacts of eliminating food groups, increasing starchy staple foods or adding sentinel unhealthy foods. We collated a global food list from dietary studies in 37 countries and used this list to develop nutrient values for a set of 35 food subgroups. We analyzed infant dietary intakes from studies in eight countries to inform maximum quantities and frequencies of consumption for these subgroups in weekly food patterns. We found that unfortified foods could meet targets for most infants for 12 nutrients, but not for iron. For the smallest and youngest infants, with the lowest energy intakes, there were additional deficits for minerals. Best-case food patterns that met targets or came as close as possible to meeting targets included ample amounts of diverse vegetables, diverse plant- and animal-source protein foods, small amounts of whole grain foods and dairy and no refined grains or added fats or sugar. There were nutrient deficits if animal-source foods or vegetables were eliminated or if unhealthy foods were included.
