The Association between the Plasma Phospholipid Profile and Insulin Resistance: A Population-Based Cross-Section Study from the China Adult Chronic Disease and Nutrition Surveillance.

The dysfunction of phospholipid metabolism enzymes and the change in membrane phospholipid composition are associated with insulin resistance, indicating that phospholipids play an important role in the regulation of insulin sensitivity. The reflection of phospholipid changes in blood might provide clues for both mechanism understanding and intervention. Using a targeted phospholipidomic approach, 199 phospholipid molecular species were identified and quantified in the plasma of 1053 middle-aged participants from a national investigation. The associations of the phospholipid matrix, clusters, and molecular species with insulin resistance were investigated. A significant association was confirmed between the phospholipid matrix and the homeostatic-model assessment of insulin resistance (HOMA-IR) by a distance-based linear model. Furthermore, three clustered phospholipid modules and 32 phospholipid molecular species were associated with HOMA-IR with the strict control of demographic and lifestyle parameters, family history of diabetes, BMI, WC, and blood lipid parameters. The overall decline in lysophosphatidylcholines (LPCs), the decrease in saturated lysophosphatidylethanolamines (LPEs), the decrease in polyunsaturated/plasmenyl phosphatidylcholines (PCs), and the increase in polyunsaturated phatidylethanolamines (PEs) were the prominent characters of plasma phospholipid perturbation associated with insulin resistance. This suggested that PC- and PE-related metabolic pathways were widely involved in the process of insulin resistance, especially the disorder of LPC acylation to diacyl-PC.

Determination of β-Galactooligosaccharides (GOS) in Infant Formula: Collaborative Study, Final Action 2021.01.

We previously published a method for the determination of β-galactooligosaccharides (GOS) in infant formula and adult nutritionals, which is currently First Action AOAC Method 2021.01. In this study, reproducibility data were collected to support the promotion of the method to Final Action. A collaborative study was organized in which 14 laboratories from eight different countries participated. Initially, laboratories were requested to analyze two practice samples and request guidance from the study director in case of issues. Successful laboratories proceeded to analyze seven samples (six infant formula and one adult nutritional) received as blind duplicates. Thirteen laboratories reported acceptable results for practice sample 1. Practice sample 2 could only be delivered to eight of the laboratories due to restrictions at customs. The 13 laboratories successfully analyzing practice sample 1 were requested to continue with the analysis of the multilaboratory trial (MLT) samples. Laboratory 14 was unable to solve some technical difficulties, so their data could not be used. Out of the seven samples tested, results for six infant formulas met the requirements of the AOAC Standard Method Performance Requirements (SMPR®) 2014.003, with repeatability (RSDr) ranging from 1.4 to 4.7% and reproducibility (RSDR) ranging from 8.1 to 11.6%. The adult nutritional sample returned results outside the range of the SMPR, having an RSDr of 9.9%, higher than the SMPR target of ≤6%, and an RSDR of 12.1%, just above the SMPR target of ≤12%. The method described is suitable for the determination of GOS in infant formula. A method is described which is suitable for the determination of GOS in infant formula.

Participant Assessment of an Alternative Flexible Congregate Nutrition Meal Program for Older Adults

Congregate Nutrition Services have long been a pillar of public health assistance, championing the independence and community engagement of older Americans. The advent of COVID-19, however, restricted access to these services due to the closure of physical locations. In response, Lanakila Meals on Wheels initiated a virtual congregate meal program, Kūpuna U, in collaboration with community partners in Honolulu County. The program combined grab-and-go or home-delivered meals with virtual and in-person classes to improve both nutrition and socialization for older adults. This study aimed to capture participant feedback to assess and enhance the Kūpuna U program, developing it as a flexible and scalable congregate meal solution applicable nationwide. Five focus group discussions were conducted with program participants (n = 34). The majority of participants were female (74%), Asian (73%), and living alone (56%). Participants found the program beneficial, enhancing their nutrition, social engagement, and learning experiences on various topics tailored for older adults. Supportive staff played a crucial role in motivating participants to stay engaged. Participants also identified potential enhancements to the program, including more activities and courses, expanded hours, additional in-person options at various locations, and culturally tailored meals.

Comparing Aluminum Concentrations in Adult and Pediatric Parenteral Nutrition Solutions: Multichamber-Bag versus Compounded Parenteral Nutrition.

Aluminum contamination in parenteral nutrition (PN) solutions can lead to neurotoxicity, reduced bone mass, and liver toxicity, especially in pediatric patients. Ingredients commonly used in PN compounding, such as vitamins, trace elements, calcium, and phosphate salts, contain significant amounts of aluminum. This study aimed to compare aluminum concentrations in multichamber-bag (MCB) and compounded PN for adults and pediatrics. A prospective study assessed aluminum concentrations in various types of MCB and compared them with compounded PN formulations with similar compositions. The types of MCB included Lipoflex® (without electrolytes), Omegaflex®, Finomel®, Smofkabiven® (with and without electrolytes), Olimel®, Clinimix®, and Numeta®. Overall, 80 aluminum determinations were included: 36 for MCBs and 44 for compounded PN. MCBs showed significantly lower aluminum concentrations than compounded PN: 11.37 (SD 6.16) vs. 21.45 (8.08) µg/L, respectively. Similar results were observed for adult (n = 40) and pediatric (n = 40) PN formulations (12.97 (7.74) vs. 20.78 (10.28) µg/L, and 9.38 (2.23) vs. 22.01 (5.82) µg/L, respectively). Significant differences were also found between MCBs depending on the manufacturing company. These findings suggest that MCBs PN offer a safer option for reducing aluminum contamination in PN. Harmonizing regulations concerning aluminum concentrations in PN solutions could help mitigate differences between PN formulations.

Dietary fibre intakes of two cohorts of New Zealand adults with and without constipation

Adequate dietary fibre (DF) intake is recommended to relieve constipation and improve gut health(1). It is often assumed that individuals with constipation have relatively low DF intake and do not meet the recommended adequate intake of 25 g and 30 g for females and males, respectively. The 2008/09 New Zealand Adult Nutrition Survey confirmed that the mean DF was 17.9 grams (g) per day for females and 22.8 g per day for males, which was well below the recommended adequate intake(2). With the continuous shift of dietary patterns over time, we sought to compare the current usual DF intake of two cohorts of New Zealand adults: those who have constipation with those without constipation but with relatively low DF intake. We report baseline dietary data from two randomised controlled dietary studies (Kiwifruit Ingestion to Normalise Gut Symptoms (KINGS) (ACTRN12621000621819) and Bread Related Effects on microbiAl Distribution (BREAD) (ACTRN12622000884707)) conducted in Christchurch, New Zealand in 2021 and 2022, respectively. The KINGS study included adults with either functional constipation or constipation-predominant irritable bowel syndrome to consume either two green kiwifruit or maltodextrin for four weeks. The BREAD study is a crossover study and included healthy adults without constipation but with relatively low DF intake (<18 g for females, <22 g for males) to consume two types of bread with different DF content, each bread for four weeks separated by a two-week washout period. All participants completed a non-consecutive three-day food diary at baseline. Dietary data were entered into FoodWorks Online Professional (Xyris Software Australia, 2021) to assess mean daily DF intake. Fifty-six adults from the KINGS study (n = 48 females, n= 8 males; mean age ± standard deviation: 42.8 ± 12.6 years) and BREAD study (n = 33 females, n= 23 males; mean age: 40.4 ± 13.4 years) completed a baseline food diary. In the KINGS study, females with constipation had a daily mean DF intake of 25.0 ± 9.4 g whilst male participants consumed 26.9 ± 5.0 g per day. In the BREAD study, females without constipation had a mean daily DF intake of 19.4 ± 5.8 g, whereas males had 22.6 ± 8.5 g per day. There was a statistically significant difference in the mean daily DF intake between females with constipation and those without constipation (p < 0.001) but not between males (p = 0.19). These two studies found that DF intakes among females with constipation were not as relatively low as previously assumed, as they met their adequate intake of 25 g. Further data analysis from the KINGS and BREAD studies will reveal the effects of using diet to manage constipation and promote better gut health in these two cohorts of New Zealand adults.

Association between dietary pattern and Helicobacter pylori infection at Queen Elizabeth Hospital, Kota Kinabalu: A case-control study

BackgroundLimited studies have reported the association between dietary patterns and Helicobacter pylori (H. pylori) infection in Sabah. ObjectiveThe purpose of this study was to assess the association between dietary pattern and H. pylori infection among patients aged 18 years and above that went for first esophagogastroduodenoscopy (OGDS) in 2021 at Queen Elizabeth Hospital (QEH), Kota Kinabalu. MethodsDietary intake of positive H. pylori was compared with healthy subjects by using questionnaire adapted from Malaysian Adult Nutrition Survey (MANS) 2014. Using logistic regression models, we evaluated the association between dietary pattern and H. pylori infection risk. FindingsOur finding identified four dietary patterns, namely “high carbohydrate pattern”, “high fiber pattern”, “high fat/cholesterol pattern” and “high salt pattern”. After adjustment for potential confounders, the highest quartile of “high salt pattern” showed greater odds of H. pylori infection (OR = 1.26; 95% Cl: 1.032–1.459; P = 0.045) than lowest quartile, while highest quartile of “high fiber pattern” demonstrated lower odd of the infection (OR = 0.69; 95% Cl: 0.537–0.829; P = 0.008) than those in lowest quartile. If compared with Recommended Nutrient Intake (RNI) 2017, positive H. pylori consumed high carbohydrates and sodium with insufficient fiber intake. ConclusionTo conclude, “high fiber pattern” lowers the risk of H. pylori infection while “high salt pattern” increases the infection risk. Our study also highlighted the importance of nutrient intake within daily allowances.

Study on the Dose-Response Relationship between Magnesium and Type 2 Diabetes of Childbearing Women in the China Adult Chronic Disease and Nutrition Surveillance 2015.

Background: Magnesium (Mg) is an essential element and participates in many metabolic pathways. Many studies have found a certain negative correlation between magnesium and blood glucose parameters, but the dose-response relationship between them is still a relatively narrow research field. We aim to explore the dose-response relationship between plasma and dietary Mg and type 2 diabetes (T2DM) among childbearing women in a nationally representative sample. And we will also initially explore the threshold of dietary and plasma magnesium in the prevention of T2DM and their consistency. Methods: A total of 2912 18-44 year-old childbearing women were recruited from the China Adult Chronic Disease and Nutrition Surveillance (2015). Multivariate logistic regression was used to explore the dose-response relationship between plasma and dietary Mg and glucose parameters. The threshold effect between Mg and T2DM was explored by a restricted cubic spline regression. Results: It was found that when plasma Mg was increased by 0.041 mmol/L, the risk of T2DM, impaired fasting glucose (IFG), and HbA1c-hyperglycemia was reduced by 18%, 19%, and 18%, respectively. The possible threshold value for plasma Mg to prevent the risk of T2DM was 0.87 mmol/L. Through the quality control of the sample dietary survey data, 2469 cases were finally included for dietary analysis. And the possible threshold value for dietary Mg to prevent the risk of T2DM was 408 mg/d. Taking the recommended dietary Mg intake of 330 mg/d as the reference group, when the Mg intake reached 408 mg/d, the risk of T2DM was significantly reduced. And the average plasma Mg level of the people whose dietary intake reached 408 mg/d was 0.87 mmol/L. Conclusions: These results indicate that dietary Mg and plasma Mg have good consistency on the threshold effect of glucose parameters in women of childbearing age.

Assessment of Adult Individuals' Fear of COVID-19, Healthy Living Behaviors, and Nutrition Knowledge Levels during the COVID-19 Pandemic Period

This study determines the fear of COVID-19, healthy lifestyle behaviors, and nutrition knowledge levels of individuals during the COVID-19 pandemic. The study was conducted involving 509 people between the ages of 18 and 64 from December 2020 to April 2021. Data were collected online using a descriptive characteristics form, the COVID-19 Fear Scale, the Adult Nutrition Knowledge Level Scale, and the Healthy Lifestyle Behaviors Scale II. It was found from the study that women feared COVID-19 more than men (p<0.05). Individuals aged 35–44 scored higher in basic nutrition knowledge, while those aged 18‒24 scored lower in food preference knowledge (p<0.05). It was also found that individuals who were between 55 and 64 years of age, married, highly educated, employed in the public sector, of good economic status, and ill scored higher on the Healthy Lifestyle Behaviors Scale II (p<0.05). A weak positive correlation was found between the score of the Fear of COVID-19 Scale and scores of both food preference knowledge and health responsibility sub-dimensions (r=0.088, r=0.181; p<0.05). A weak positive correlation was also found between the nutrition knowledge score as well as the different sub-dimensions and the total score of the Healthy Lifestyle Behaviors Scale II (r=0.164, r=0.196; p<0.05). It was observed that fear of COVID-19, nutrition knowledge level, and healthy lifestyle behaviors were influenced by various socio-demographic characteristics, and that there was a relationship between these three elements.

Healthy Nutrition for Adults With Intellectual Disability: Piloting a Mobile Health Application and Self-Management Intervention.

While there are many benefits to healthy nutrition, adults with intellectual disability often have poor nutrition habits. The purpose of this pilot study was to examine the use of a nutrition app and self-management intervention to increase awareness of healthy nutrition choices for adults with intellectual disability. Data was gathered on the effectiveness of the intervention and social validity of intervention components. Through a single-case multiple-baseline across participants design, the mobile nutrition app with self-management intervention was effective in increasing awareness of healthier nutrition items for three adults with an intellectual disability. Future research is needed to replicate and generalize findings, as well as explore additional supports that may be needed for individuals who have more extensive support needs.

[Artículo traducido] Detección y reducción de errores en la elaboración de la nutrición parenteral mediante control gravimétrico y de producto

ObjectiveTo analyze the errors in the preparation of parenteral nutrition in a Pharmacy Service, detected through an already consolidated gravimetric and product quality control, and compare them with those detected during the initial years of implementing this quality control. MethodsAll errors detected through quality control in the compounding of pediatric and adult parenteral nutrition between 2019 and 2021 were prospectively analyzed. This quality control consisted of 3 sequential processes: a visual check, a gravimetric control, and a product control. Errors were classified as gravimetric, when the nutrition had a deviation of more than 5% from the theoretical weight, or as product errors when a qualitative or quantitative error was detected upon reviewing the remainder of the components used. These errors were analyzed in terms of type and the component involved. A comparison was made with the errors detected during the implementation phase of this quality control from 2016 to 2018. ResultsA total of 41,809 parenteral nutritions were reviewed, and 345 errors were detected (0.83% of the preparations); of these, 59 errors were found in pediatric nutritions (0.68% of them), and 286 in adult nutritions (0.86% of them). Among these errors, 193 were of gravimetric nature, while 152 were detected through product control. The main components involved in product errors were electrolytes, primarily due to the addition of excessive volumes and the use of incorrect components. A significant absolute reduction of 0.71% (p < 0.05) in the total number of errors was observed when compared to the implementation phase. This reduction was consistent in both gravimetric errors (−0.59%) and product-related errors (−0.12%) (p < 0.05). ConclusionsComprehensive quality control of parenteral nutrition preparation is an easily implementable tool that effectively detected and prevented significant errors. Furthermore, its widespread adoption contributed to a reduction in the overall error count.

Adequate iodine nutrition and higher salt intake in Chinese adults aged 18–59 years recommended by international organizations

Iodine deficiency and excessive salt intake have adverse health effects. This study evaluated the iodine level and salt intake in Chinese adults aged 18–59 years after implementing the salt reduction program and compared with both the World Health Organization (WHO) and Chinese recommendations. Adults aged 18–59 years were randomly selected using multi-stage stratified random sampling in coastal urban area (CUA), non-coastal urban area (Non-CUA), coastal rural area (CRA), and non-coastal rural area (Non-CRA) of Fujian Province, China. Iodine, sodium, and creatinine concentrations in spot urine samples were measured. Knudsen equation was used to determine 24-h urinary iodine and sodium excretion. The median urinary iodine concentration (mUIC) and urinary sodium concentration (mUNaC) among adults (n = 3513) were 132.0 μg/L and 4.0 g/d, respectively. The mUIC and median daily iodine intake in CUA, Non-CUA, CRA and Non-CRA were 112.1, 127.5, 128.5, 167.5 μg/L and 189.6, 182.5, 199.4, 236.0 μg/d, respectively. The mUNaC and median daily salt intake (mDSI) in these four areas were 2.4, 2.8, 2.9, 2.9 g/L and 9.8, 10.4, 10.4, 10.6 g/d, respectively. The mUIC and DII of residents were higher in the Non-CRA than in the other three areas (P < 0.05). The UNaC and DSI of residents were lower in the CUA than in the other three areas (P < 0.05). The logistic regression demonstrated that the people living in CUA and Non-CUA consumed less salt compared with those in Non-CRA. Except for Non-CUA, the DII was lower (< 150 μg/d) among women of childbearing age in the low–salt intake group (< 5 g/d) compared with the high–salt intake group (≥ 5 g/d) (P < 0.05). Iodine nutrition in Chinese adults aged 18–59 years was sufficient, but the salt intake was substantially higher than the WHO and Chinese recommendations. Further policy implementation is needed to reduce salt intake and improve the monitoring of iodine levels in Chinese adults, especially in women of childbearing age.

The awareness rate of knowledge of chronic diseases and influencing factors among 4790 adults in anhui province: An online survey using WeChat

ObjectiveTo investigate public awareness about core information regarding chronic diseases and identify factors influencing that awareness among Anhui Province residents, provide a scientific basis for policy-making, and formulate corresponding intervention measures. MethodsFrom March to April 2021, 12 provincial-level representative counties and districts of Anhui province in the China Adult Chronic Disease and Nutrition Surveillance were selected as survey sites, and 4790 residents were recruited for the survey using stratified multi-stage cluster random sampling. Basic details about the study participants were collected and their awareness of core information about major chronic diseases was measured through an online survey using WeChat. ResultsIn 2021, the awareness rate of core information about chronic diseases among residents of Anhui Province was 54.93%. Multivariate logistic regression analysis showed that a higher awareness rate was associated with the following factors: non-housework occupations (agriculture, forestry, animal husbandry, and fishery: OR = 1.309, commercial services and production and transportation: OR = 1.450, institutions, and professional and technical personnel: OR = 1.461), a high education level (high school/junior high school/technical school OR = 1.357, college and above OR = 2.133), and residence in the southern and northern Anhui areas (southern Anhui OR = 1.282, northern Anhui OR = 1.431); whereas in rural areas (by district and country) (OR = 0.863), the awareness rate was low (all P < 0.05). ConclusionsThe awareness rate of core information about chronic diseases among residents of Anhui, China, is low. It is necessary to strengthen awareness about chronic disease prevention and management by targeting specific groups of people in this region.

Prevalence and trends of low body weight among elderly population aged 60 years and above in China in 2002-2015

Understand the current situation and changing trends of low body weight in elderly population aged 60 years and above. Data was collected from 2002 Chinese Nutrition and Health Survey, 2010-2013 Chinese Nutrition and Health Surveillance and 2015 Chinese Adult Chronic Disease and Nutrition Surveillance. Multi-stage stratified cluster random sampling was used for all surveys or surveillance. In 2002, 27 778 samples of people aged 60 and over were taken from 132 monitoring sites in mainland China. In 2010-2013, 34 581 subjects were selected from 150 monitoring points in mainland China. In 2015, 59 576 subjects were selected from 302 monitoring points in mainland China. Questionnaires collected basic information such as gender, and date of birth, and information such as height and weight were collected through physical examination. The prevalence of low body weight in the elderly aged 60 years and above showed a downward trend from 2002 to 2015 in China(P&lt;0.01). The prevalence of low body weight decreased from 11.67% in 2002 to 5.19% in 2015. The prevalence of low body weight among males decreased from 11.51% in 2002 to 5.21% in 2015. The prevalence of low body weight among females decreased from 11.83% in 2002 to 5.17% in 2015. The prevalence of low body weight in the elderly aged 60 years and above showed an upward trend with age. The prevalence of low body weight in urban areas decreased from 5.85% in 2002 to 3.31% in 2015. The prevalence of low body weight in rural areas decreased from 16.25% in 2002 to 6.67% in 2015. The prevalence of low body weight in seven geographic regions of China decreased from 2002 to 2015. The prevalence of low body weight was highest in the elderly population aged 60 years and above in South China(9.49%(95%CI 8.61%-10.38%)) and lowest in North China(2.55%(95%CI 2.15%-2.95%)) in 2015. The prevalence of low body weight among the elderly aged 60 years and above in China decreased from 2002 to 2015. The prevalence of low body weight increased with age. The prevalence was higher in rural areas than in urban areas, and the prevalence in South China was higher than in other geographic regions.

Nutritional Status, Sex, and Ambient Temperature Modulate the Wingbeat Frequency of the Diamondback Moth Plutella xylostella.

The diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae), is a cosmopolitan horticultural pest that is undergoing a fast, climate-driven range expansion. Its wide geographic distribution, pest status, and high incidence of insecticide resistance are directly tied to long-distance migration. Wingbeat frequency (WBF) is a key aspect of P. xylostella migratory behavior, but has received limited scientific attention. Here, we investigated the effects of environmental parameters, age, adult nutrition, and sex on P. xylostella WBF. Across experimental regimes, WBF ranged from 31.39 Hz to 78.87 Hz. Over a 10-35 °C range, the WBF of both male and female moths increased with temperature up to 62.96 Hz. Though male WBF was unaffected by humidity, females exhibited the highest WBF at 15% relative humidity (RH). WBF was unaffected by adult age, but adult nutrition exerted important impacts. Specifically, the WBF of moths fed honey water (54.66 Hz) was higher than that of water-fed individuals (49.42 Hz). Lastly, males consistently exhibited a higher WBF than females. By uncovering the biological and (nutritional) ecological determinants of diamondback moth flight, our work provides invaluable guidance to radar-based monitoring, migration forecasting, and the targeted deployment of preventative mitigation tactics.

Identification and development of implementation strategies: the important role of codesign.

To date, implementation strategies reported in the literature are commonly poorly described and take the implementation context insufficiently into account. To unravel the black box of implementation strategy development, insight is needed into effective theory-based and practical-informed strategies. The current study aims to describe the stepwise development of a practical-informed and theory-based implementation strategy bundle to implement ProMuscle, a nutrition and exercise intervention for community-dwelling older adults, in multiple settings in primary care. The first four steps of Implementation Mapping were adopted to develop appropriate implementation strategies. First, previously identified barriers to implementation were categorized into the constructs of the Consolidated Framework for Implementation Research (CFIR). Second, the CFIR-ERIC matching tool linked barriers to existing implementation strategies. Behavioral change strategies were added from the literature where necessary. Third, evidence for implementation strategies was sought. Fourth, in codesign with involved healthcare professionals and implementation experts, implementation strategies were operationalized to practical implementation activities following the guidance provided by Proctor et al. These practical implementation activities were processed into an implementation toolbox, which can be tailored to a specific context and presents prioritized implementation activities in a chronological order. A previous study identified and categorized a total of 654 barriers for the implementation of a combined lifestyle intervention within the CFIR framework. Subsequently, the barriers were linked to 40 strategies. Due to the fact that many strategies impacted multiple barriers, seven overarching themes emerged based on the strategies: assessing the context, network internally, network externally, costs, knowledge, champions, and patient needs and resources. Codesign sessions with professionals and implementation experts resulted in the development of supported and tangible implementation activities for the final 20 strategies. The implementation activities were processed into a web-based implementation toolbox, which allows healthcare professionals to tailor the implementation activities to their specific context and guides healthcare professionals to prioritize implementation activities chronologically during their implementation. A theory-based approach in combination with codesign sessions with stakeholders is a usable Implementation Strategy Mapping Method for developing a practical implementation strategy bundle to implement ProMuscle across multiple settings in primary care. The next step involves evaluating the developed implementation strategies, including the implementation toolbox, to assess their impact on the implementation and adoption of ProMuscle.

P1207 Microbiome composition determines sustained remission after the Crohn’s Disease Exclusion Diet (CDED) with or without Partial Enteral Nutrition in adults with mild-moderate Crohn’s disease; Results from the CDED-AD Pilot Randomized Controlled Trial

Abstract Background The Crohn's Disease (CD) Exclusion Diet (CDED) is an established dietary therapy for children with active mild-to-moderate CD. A recent randomized controlled trial showed efficacy in mild-to-moderate CD in adults. We have previously demonstrated the impact of CDED on the microbiome of children. The aim of this work was to assess if we can determine sustained clinical remission (SCR) from the baseline microbiome composition and examine the effect of CDED on microbiome composition in adult CD. Methods This was an open-label, prospective, randomized, controlled pilot trial involving patients with mild-to-moderate CD and evidence of active inflammation. Patients were randomly assigned to receive CDED with partial Enteral Nutrition (PEN) or CDED alone, both for 24 weeks. The V4V5 region of the 16S rRNA gene was amplified and sequenced, and reads were processed using QIIME2 and the SILVA database. Relationships between the microbiome, SCR, and Fecal Calprotectin (FC) were analyzed using logistic regression, Poisson Principal Component Analysis, paired T-Tests and subsampling ranking forward selection. Results Clinical remission (CR) at weeks 6, 12 and 24 was achieved in 62.5%, 52.5%, and 50% of patients, respectively. Week 0, 6, 12 and 24 stool samples were available for 35,32,30 and 26 patients, respectively. In patients with SCR, defined as remission at both weeks 12 and 24, the baseline microbiome revealed lower alpha diversity compared to those without SCR (p=0.018), and differing Microbiome principal components (PC) scores (p &amp;lt; 0.01). PC1 and PC3, characterized mainly by Alistipes, Faecalibacterium and UCG-002 predicted SCR (P&amp;lt;0.01). PC2 predicted elevated FC&amp;gt;250 µg/g at week 12 (p=0.004). Baseline abundance of Haemophilus was associated with decreased SCR probability (p&amp;lt;0.01). At week 6 in the entire cohort, there was a significant decrease in Actinobacteriota (p=0.035) and a significant increase in Bacteroidota (p=0.003). Additionally, there was a significant increase in several genera, including beneficial Alistipes and Oscillibacter (p&amp;lt;0.02) in those who achieved CR after 6, 12, or 24 weeks. Higher Firmicutes at week 6 were associated with FC&amp;lt;250 at week 12 (p=0.031). An uncultured genus from the Oscillospiraceae family was significantly associated with a decrease in the probability of SCR (p&amp;lt;0.01) and was significantly increased at week 6 in patients who did not attain CR (p&amp;lt;0.05). Conclusion The baseline microbiome composition was associated with SCR and FC&amp;lt;250 at week 12 in adult patients treated with CDED (with or without PEN) over 24 weeks. This suggests that the microbiome could be useful tool to identify patients who would benefit from long-term dietary intervention.

Determination of Seven Human Milk Oligosaccharides (HMOs) in Infant Formula and Adult Nutritionals: First Action 2022.07.

Human milk oligosaccharides (HMOs) are important components of breast milk and may be responsible for some of the benefits of breastfeeding, including resistance to infections and the development of a healthy gut microbiota. Selected HMOs are now available for addition to infant formula, and suitable methods to control the dosing rate are needed. To develop and validate a suitable method for the analysis of HMOs in infant formula. A method was developed for the determination of seven human milk oligosaccharides (2'-fucosyllactose, 3-fucosyllactose, 3'-sialyllactose, 6'-sialyllactose (6'SL), 2',3-difucosyllactose, lacto-N-tetraose (LNT), lacto-N-neotetraose (LNnT)) in infant formula and adult nutritionals. The oligosaccharides are labeled at their reducing end with 2-aminobenzamide, separated by liquid chromatography and detected using a fluorescence detector. Maltodextrins are enzymatically hydrolyzed before analysis to prevent potential interference; likewise, an optional β-galactosidase treatment can be used to remove β-galactooligosaccharides. Fructooligosaccharides or polydextrose do not generally interfere with the analysis. The method has been validated in a single laboratory on infant formula and adult nutritionals. The seven HMOs were spiked into eight matrixes at three or four spike levels, giving a total of 176 data points. Recoveries were in the range of 90.9-109% in all cases except at the lowest spike level in one matrix (elemental formula), where the LNT recovery was 113%, the LNnT recovery was 111%, and the 6'SL recovery was 121%. Relative repeatabilities (RSD(r)) were in the range of 0.1-4.2%. The performance is generally within the requirements outlined in the Standard Method Performance Requirements (SMPR®) published by AOAC INTERNATIONAL. The method developed is suitable for the determination of seven HMOs in infant formula and demonstrated good performance during single-laboratory validation. A method has been developed that is suitable for the determination of seven HMOs in infant formula.

Feeding and Nutrition for People with Dementia in Gerontological Services: A Focus Group Study.

This work sought to describe the experience of managers and caregivers with feeding and nutrition for older adults with dementia, in Colombian gerontological services. This is a qualitative focus group study with fourteen gerontological care centers for people with dementia. The study reveals that care related to food and nutrition for people with dementia is organized based on the comprehensive assessment of the resident. Although there are basic support strategies, each caregiver requires specific knowledge, attitudes, behaviors, and institutional support, to generate a context that favors the health and quality of life of those involved. The experience of caring for people with dementia in aspects related to their food and nutrition, seen from the perspective of managers and caregivers of gerontological services in a developing country, strengthens specific strategies and public policies. This, in turn, reduces the burden on caregivers.

Assessing the impact of dietary choices on fiber deficiency: insights from the 2017-2020 Polish national adult nutrition survey.

Dietary fiber is a key component of a healthy diet, associated with a reduced risk of cardiovascular disease, obesity, type 2 diabetes, certain cancers, chronic inflammation, or depression. The aim of the study was to perform an in-depth analysis of dietary fiber intake in the Polish population, taking account of the consumption of groups of products that are fiber sources and identify any age-related differences in the dietary fiber intake of the subjects. We analyzed data obtained from two representative cross-sectional studies on the diet and nutritional status of adult Polish residents including the total of 4,000 individuals aged 19 years and more. Two 24-h recalls were used per individual to assess the diet using the computer-assisted personal interview (CAPI) technique. Total fiber content and fiber contained in cereal products, vegetables, fruits, legumes, nuts and seeds were calculated. Fiber intake was compared to the recommendations: 25 g/d for adults up to 65 years of age and 20 g/d for those aged 66 years and older. All statistical analyses, including the Pearson's chi-squared test, the Student's t-test, and the Analysis of Variance (ANOVA), were conducted using STATISTICA™ version 13.3, with the results being adjusted for demographic distribution biases to enhance the representativeness. The average daily fiber intake was 17.83 ± 0.14 g/day (78% of the recommended intake), with 20.5% of respondents meeting the requirement. More men than women (27.05% vs. 14.3%;) met the requirement and men were characterized by a higher average intake (19.34 ± 0.20 g/day) than women (16.43 ± 0.19 g/day). The main fiber sources were cereals (44.1%), vegetables (23.6%), and fruits (16.0%). As regards men, the sources included refined bread (25.8%), vegetables (23.1%), and fruits (10.2%) and for women, they were vegetables (24.0%), fruits (17.2%), and refined bread (16.3%). Although refined bread is not recommended as a primary fiber source due to its lower fiber content compared to whole grain bread, its high consumption significantly contributed to the total fiber intake. The prevalence of widespread dietary fiber deficiency calls for the intensification of educational efforts that address the health advantages and sources of dietary fiber, as well as methods for its inclusion in daily meals.

A Narrative Review: Analysis of Supplemental Parenteral Nutrition in Adults at the End of Life.

"End of life" is a stage defined by the existence of an irreversible prognosis that ends with a person's death. One of the aspects of interest regarding end of life focuses on parenteral nutrition, which is usually administered in order to avoid malnutrition and associated complications. However, parenteral nutrition can be adapted to specific circumstances and evolve in its functionality through supplementation with certain nutrients that can have a beneficial effect. This narrative review aims to carry out a situation analysis of the role that could be adopted by supplemental parenteral nutrition in attenuating alterations typical of end of life and potential improvement in quality of life.
