This study aimed to explore the potential of these two DASH diet self- management apps for controlling blood pressure in the Saudi Arabian context.Fifteen patients were recruited at King Abdullah bin Abdulaziz University Hospital in Riyadh, Saudi Arabia. Ten patients had hypertension, and five had prehypertension (mean age = 45). Patients were given the two apps and asked to try each for one week. Focus groups (n=4) were held at the end of the trial to understand the patient perceptions of the apps.

Healthy women were randomised to receive an intervention of low GI dietary advice or routine antenatal care from early pregnancy. All women completed a 3-day food diary in each trimester of pregnancy. Estimates of maternal intake of sugar in each trimester were averaged to provide mean intakes during pregnancy. Mothers reported current doctor-diagnosed eczema in their children at 2-years of age (n=271), and current doctor-diagnosed asthma and eczema in their children at 5 (n=357) and 9-11 years (n=391) of age. Multivariable logistic regression models were used a) to test the effect of the intervention on child outcomes overall, and stratified by maternal education level (with, versus without, a complete tertiary level education), and b), in observational analyses, to analyse the relation between sugar and carbohydrate intake in pregnancy and child outcomes.There was weak evidence overall for a reduction in asthma at 5-years of age in children whose mothers received the low GI dietary intervention during pregnancy compared to usual care [adjusted odds ratio (OR) 0.43 (95% CI 0.18, 1.03); <jats:italic>P</jats:italic>=0.06].

The dietary intakes were adjusted to a 2000 kcal/day diet, to assess diet quality independently of diet quantity. Non-fasting serum cholesterol, hs-CRP, and plasma α- tocopherol, vitamin C and retinol concentrations were also measured at this time-point. Data collected via a self-administered Health and Lifestyle Questionnaire were used to establish classification of a number of variables. Analyses were conducted on sub-samples with a DII<jats:sup>®</jats:sup> score and measures of hs-CRP (8,034 men and 9,861 women), and concentrations of vitamin C (9,866 men and 11,702 women), retinol (3,673 men and 3,517 women) and cholesterol-adjusted α- tocopherol (3,623 men and 3,476 women). Analysis of covariance and linear regression were used to study associations across sex-specific quintiles of the DII<jats:sup>®</jats:sup> score (adjusted for age, BMI, smoking status, physical activity, social class and educational level), where a higher score indicates a more pro-inflammatory diet.Mean concentrations in men and women were 2.99 and 3.09 mg/L for hs-crp, 47 and 59 μmol/L for vitamin C, 53 and 50 μg/dL for retinol and 4.34 and 4.42 μmol/mmol for cholesterol-adjusted α- tocopherol, respectively. In both men and women, mean hs-CRP was higher if the diet was more pro-inflammatory (p-trend = 0.02 in men and 0.07 in women), while concentrations of vitamin C, retinol and α-tocopherol were significantly lower (p-trend < 0.001). Positive associations for hs-CRP, but negative associations for plasma concentrations of vitamin C, retinol and α-tocopherol were evident in both men and women, after adjustments for covariates (p-trend < 0.001). The differences between Q1 and Q5 adjusted means for hs-CRP, vitamin C, retinol and α-tocopherol were +9.4%, -22.1%, -3.9% and -8.6% in men and +7.9%, -17.5%, -4.8% and -7.6% in women, respectively.We observed statistically significant positive associations between the DII<jats:sup>®</jats:sup> score and hs-CRP, a well-known inflammatory biomarker, whilst significant negative associations were found for circulating concentrations of three anti-inflammatory vitamin","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":"26 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141527310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thematic analysis was conducted, and emerging themes and subthemes were identified.Our findings indicate that a significant portion of participants in our study are involved in providing nutrition and diet advice for various health conditions. The majority of pharmacists considered diabetes programmes having a high level of importance (84%), followed by weight management services (78%), hypertension management (86%), and healthy diet campaigns (63.5%). However, our knowledge and confidence rating questions revealed a significant gap in training and a clear need for educational materials tailored for pharmacists to enhance their ability to provide nutrition advice effectively. Key themes identified in open-text questions were referrals and collaboration, training and education needs, wider needs (changes in the public health system, materials/resources, integration and implementation of nutrition in pharmacy practice) and perceived roles as pharmacists in providing nutrition advice (patient support, feeling responsible, specialised focus areas).Qualitative findings underscore the pressing demand for nutrition training and education to deliver comprehensive services, as well as the necessity for collaborative efforts with dietitians and nutritionists to ensure effective care and the improvement of referral pathways in pharmacy practice.This ","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":"143 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141527462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The global COVID-19 pandemic has greatly accelerated the adoption of telehealth among clinical nutritionists. For instance, in the USA, telehealth usage for nutritional care has increased from 37% to 78% among clinical nutritionists <jats:sup>(3)</jats:sup>, while in Italy, the adoption of telenutrition services by Registered Dieticians (RDNs) has risen from 16% to 63% <jats:sup>(4)</jats:sup>. These statistics highlight the rapid integration of telehealth into dietetics practices as a response to the global health crisis, reflecting a growing trend towards virtual care delivery as an effective method for providing nutritional care. While telehealth has made progress in Saudi Arabia (5), there is a research gap regarding its prevalence and effectiveness in dietetics practice. This study aims to evaluate the current implementation of telehealth in dietetics practice during the COVID-19 pandemic in Saudi Arabia.In this cross-sectional, a web-based online survey was used from mid-December 2022 to mid-May 2023. The study was distributed in several Saudi Arabian regions including (central, western, eastern, south, and north) and was completed by 306 clinical Registered Dietitians (RDNs) in public and private healthcare facilities who met the study’s inclusion criteria. The survey consisted of 28 questions divided into four sections, covering sociodemographic information, past or current experiences, obstacles and challenges of telehealth usage, and the future prospects of telehealth. In this study, participants were requested to reflect on their current observations and previous experiences pertaining to the utilisation of telehealth in the field of dietetics. To ensure the validity and relevance of the survey, it was reviewed by a panel of experienced dietitians in Saudi Arabia to obtain their feedback before being used to collect data.Our research findings reveal that 76% of RDNs in Saudi Arabia utilize telehealth in their practice. The most common obstacles reported by RDNs using telehealth include internet connectivity issues (21.9%), patient disengagement and lack of enthusiasm (21.3%), and difficulties in coordinating with patients (21%). Telehealth interventions used by RDNs primarily involve diet recall (33.7%), weight- related measurements (30.6%), lab findings (26%), and only 8% reported using telehealth for vital signs. A majority of participants (69.4%) believed that telehealth could improve patient accessibility and help reduce no-show rates (68.9%). Additionally, over 70% of participants agreed that telehealth offers them flexibility in inpatient consultations.In conclusion, telehealth is widely utilised among RDNs in Saudi Arabia, with potential benefits such as decreased no-show rates.

The aim of this study was to explore the association between selenium status (serum selenium and selenoprotein P (SELENOP)) and global cognitive performance at baseline and after 5 years in 85-year-olds living in the Northeast of England.Serum selenium and SELENOP concentrations were measured at baseline by total reflection X-ray fluorescence (TXRF) and enzyme-linked immunosorbent assay (ELISA), respectively, in 757 participants from the Newcastle 85+ study. Global cognitive performance was assessed using the Standardized Mini-Mental State Examination (SMMSE) where scores ≤25 out of 30 indicated cognitive impairment. Logistic regressions explored the associations between selenium status and global cognition at baseline. Linear mixed models explored associations between selenium status and global cognition prospectively after 5 years. Covariates included sex, body mass index, physical activity, high sensitivity C-reactive protein, alcohol intake, self-rated health, medications and smoking status.At baseline, in fully adjusted models, there was no increase in odds of cognitive impairment with serum selenium (OR 1.004, 95% CI 0.993-1.015, p = 0.512) or between SELENOP (OR 1.006, 95% CI 0.881-1.149, p = 0.930).

Further research is needed to explore the effect of selenium on global cognition in very old adults.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":"49 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141527308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pakistani immigration to the UK has resulted in a dynamic cultural exchange, including modifications in culinary preferences and practices among Pakistani ethnic groups. Prior research indicates that second-generation adults exhibit more signs of acculturation in their choice of diets than their first-generation counterparts &lt;jats:sup&gt;(2)&lt;/jats:sup&gt;. There is limited understanding of the food habits or the effects of acculturation on this group. The primary purpose of this study was to investigate intergenerational disparities in food preferences among Pakistani immigrants and the impact of dietary acculturation.This cross-sectional study examined the food habits and acculturation experiences of 51 first (1G) and 51 second-generation (2G) participants of the Pakistani community living in London. Data was collected using survey questionnaires modified from previous studies &lt;jats:sup&gt;(3,4)&lt;/jats:sup&gt;. We compared traditional foods like paratha and samosa with Western options like fish and chips through a set of questions, from which a dietary score was calculated (Global scale) &lt;jats:sup&gt;(5)&lt;/jats:sup&gt;. We measured food acculturation using a 5-point scale, with higher scores indicating greater Western influence and lower scores indicating less Western acculturation. Scores ranged from 6 to 30 and were categorised as low, moderate, high, or very high. Data was analysed using SPSS (version 28.0). Chi-square and t-tests were applied to identify differences between groups with significance levels set to &lt;jats:italic&gt;p&lt;/jats:italic&gt;&lt;0.05.Most of the participants were male (67%) with 38.8% aged 36-45 years.

This study aims to compared between chicken and plant-based chicken analogues in terms of nutritional composition and degree of protein hydrolysis.Proximate analyses were performed for raw and cooked samples to assess protein, fat, and energy concentrations in two chicken samples (breast and thigh) and four commercial plant-based chicken (P-C1[Wheat Protein 37%, Pea Protein 10%], P-C2 [ Soya Protein 63%], P-C3 [ Soya and Wheat Protein 83%], and P-C4 [Soya Protein 30%, Pea Protein 2%]). As a first step, the proximate analyses were assessed for the averaged samples, then the product-cooking interactions was assessed using a one-way ANOVA followed by Tukey test (p &lt;0.05). &lt;jats:italic&gt;In vitro&lt;/jats:italic&gt; digestion was performed following the INFOGEST harmonised static &lt;jats:italic&gt;in vitro&lt;/jats:italic&gt; digestion model &lt;jats:sup&gt;(2)&lt;/jats:sup&gt; for cooked samples. After digestion, o- Phthaldialdehyde (OPA) assay was carried out to measure the degree of protein hydrolysis for each sample, and two-way ANOVA test was performed.Protein content of chicken was higher compared with the plant-based chicken, whereas fat content and energy concentrations were higher in plant-based chicken. The protein content of chicken was higher for raw and cooked samples (raw: 19.8 ± 0.38 g/100 g; cooked: 30.55 ± 4 g/100g), compared with plant-based chicken (raw: 13.8 ± 5.3 g/100 g; cooked: 23.4 ± 4.5 g/100g). Plant-based chicken have a higher fat content and energy concentrations for raw and cooked samples (raw:6.52 ± 1.5 g/100 g; cooked: 9.6 ± 3.17 g/100g) and (raw:189.4 ± 28.1 g/100 g; cooked: 291.3 ± 48.1 g/100g) respectively; compared to chicken fat content (raw:4.6 ± 2.7 g/100 g; cooked: 6.1 ± 4 g/100g) and energy concentration (raw:150.9 ± 25.4 g/100 g; cooked: 228.3 ± 20.7 g/100g). The product-cooking interactions showed a significant increase (P ≤0.0001) in the protein content (raw: 15.6 ± 2.3g/100g to 19.8 ± 0.74 g/100g; cooked: 21.4 ± 0.55 g/100g to 33.06 ± 0.71 g/100g), and fat content P&lt;0.001 (raw: 2.7 ± 0.06 g/100g to 8.3 ± 0.27 g/100g; cooked: 3.29 ± 0.19 g/100g to 13.22 ± 0.33 g/100g) in both chicken and plant-based chicken samples.
