Nutrition Messaging by Healthcare Students: A Mixed-Methods Study Exploring Social Media Usage and Digital Competence.

AIM: The COVID-19 pandemic leads to a significant digital transformation in higher education and healthcare practices. This study aimed to investigate the level of digital competence, views and experiences, social media usage, and perceived barriers to digital communication among healthcare students. METHOD: Employing a mixed-methods approach, quantitative data were gathered through an online survey, while qualitative insights were gleaned from semi-structured questionnaire responses obtained during focus group discussions. A total of 143 nursing and midwifery students from Turkey, along with 54 dietetics students from various European countries, participated in the study. RESULTS: A significant proportion of nursing (43.5%) and midwifery (55.2%) students advocated for integrating digital technology training into university curricula. Instagram has emerged as the predominant platform for sharing healthcare/nutrition information among students. However, concerns have been raised regarding the prevalence of "before/after" posts on social media promoting weight loss, which were identified as low-quality content by participants. CONCLUSIONS: These findings underscore the importance of integrating digital technologies and social media into healthcare, nutrition education, and practice. Additionally, there is a pressing need to establish professional and ethical standards for digital nutritional communication. By addressing these challenges, educators can better equip healthcare students to navigate the complexities of modern healthcare practices and enhance patient-care outcomes.

The safety and efficacy of probiotic supplementation for critically ill adult patients: a systematic review and meta-analysis.

CONTEXT: The safety and efficacy of probiotics during severe illness has been a subject of ongoing interest. The impact of probiotics can worsen nutritional status, which could potentially result in a deterioration of the patient's overall life-threatening status. OBJECTIVE: This systematic review and meta-analysis evaluated the safety and efficacy of probiotics in reducing intensive care unit (ICU)-acquired infections in adult critically ill patients. DATA SOURCES: PubMed and Cochrane library databases for the period 2011-2020 were searched. DATA EXTRACTION: Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (PRISMA) methodology was used to search for randomized controlled trials that evaluated the use of probiotics among critically ill patients. DATA ANALYSIS: No significant difference was observed between probiotics and control groups in terms of the mortality rate (risk ratio 1.13, 95% confidence interval .82 to 1.55, P = .46). Probiotics, however, provided a significant reduction in ICU-acquired infections (risk ratio .73, 95% confidence interval .58 to .93, P = .01). CONCLUSION: The use of probiotics seems to play a role in decreasing the incidence of ICU-acquired infections. Also, a potential reduction in terms of the incidence of diarrhea has been reported, with no examples of adverse incidents, suggesting probiotics are safe.

Impact of enteral immunonutrition on infectious complications and immune and inflammatory markers in cancer patients undergoing chemotherapy: A systematic review of randomised controlled trials.

BACKGROUND: There is increasing awareness of the importance of nutritional support in cancer treatment including the interaction with immunity. Immunonutrition is the provision of one or more nutrients (e.g. Vitamins A, D, or E, omega-3 fatty acids, arginine and glutamine) known to modulate immune function when given at levels above those normally encountered in the diet in order to support immune system function or modulate its activity, including control of inflammation. We reviewed the role of oral or enteral immunonutrition versus standard nutrition on infection and infection-related biomarkers in adult cancer patients undergoing chemotherapy. METHODS: A systematic search of oral or enteral immunonutrition versus standard nutrition in adult cancer patients during chemotherapy with or without radiotherapy or haematopoietic stem cell transplant was conducted in MEDLINE, EMBASE and CENTRAL. The search was limited to randomised controlled trials. Our primary outcome was infectious episodes or immune-related biomarkers (e.g. immune cell numbers, inflammatory markers). Secondary outcomes included incidence of malnutrition or cachexia, non-infection related adverse events (AEs), rate of remission, survival, and delays or incomplete cycles of chemotherapy. Risk of bias was assessed using ROB 2.0 and study quality was assessed using CASP for RCTs. RESULTS: The search yielded seven studies involving 521 patients (261 immunonutrition, 260 control) for analysis. All studies enrolled patients with solid tumours (no haematological malignancies). Studies were heterogenous for cancer type (upper gastrointestinal, head and neck, pancreatic and lung), immunonutrient composition (omega-3 fatty acids, vitamin A, E, glutamine, arginine or nucleotides), delivery route (enteral nutrition or oral nutritional supplement) and control used. Intervention period ranged from 4 to 14 weeks. No study reported absolute number of infections. Three studies reported AEs including potential infectious episodes of febrile neutropenia, pneumonitis and mucositis with oral candidiasis. Some studies report a decrease in blood concentrations of CRP and TNF-α with immunonutrition. CONCLUSION: There is currently insufficient evidence to define a role for immunonutrition on infectious episodes during chemotherapy in adult cancer patients. Further well-defined studies that account for degree of malnutrition, dose, timing and duration of immunonutrition in specific well-defined cancer groups using a standardised outcome framework are needed.

Efficacy of lifestyle intervention program for Arab women with prediabetes using social media as an alternative platform of delivery.

AIMS/INTRODUCTION: This 6-month interventional study aimed to investigate the effectiveness of different educational programs among Saudi women with prediabetes referred by primary care. MATERIALS AND METHODS: A total of 253 (100 group education program [GEP], 84 WhatsApp education program [WEP] and 69 control group [CG]) eligible participants were invited to take part in the study, out of whom 120 received intervention (40 GEP, 43 WEP and 37 CG). GEP participants received focused, individualized lifestyle modification advice with bimonthly support sessions, WEP participants received the same intervention, but delivered through social media (WhatsApp). The CG received standard care. Anthropometrics, biochemical profiles and macronutrient intake were measured at baseline, and 3 and 6 months. The primary end-points were glycated hemoglobin and weight, with lipids and dietary changes as secondary outcomes. RESULTS: Glycated hemoglobin significantly improved in all groups post-intervention (GEP baseline 6.0 ± 0.2 vs 6 months 5.5 ± 0.54; P < 0.001, WEP 6.0 ± 0.26 vs 5.3 ± 0.51; P < 0.001, CG 6.0 ± 0.37 vs 5.7 ± 0.49; P < 0.001), but with no difference in between-group comparisons (P = 0.33). Within-group comparisons showed a reduction in weight, but only in the GEP group (90.6 kg ± 27.3 vs 84.8 kg ± 24.3; P < 0.01), and this was significant in between-group comparison (P = 0.003). Significant between-group comparisons with respect to energy (g) intake (P = 0.005) were also observed, as well as triglycerides (P < 0.001) and low-density lipoprotein cholesterol (P = 0.001), all in favor of the GEP group. CONCLUSIONS: Diabetes prevention programs, whether delivered through a focused educational group, social media or standard care, are equally efficacious in improving glycated hemoglobin levels among Saudi women with prediabetes, but a focused educational group was more effective in terms of successful weight loss.

The nutrition transition in Malaysia; key drivers and recommendations for improved health outcomes.

BACKGROUND: The main purpose of this paper is to understand the multidimensional phenomenon of the nutrition transition in Malaysia, from 1980 to 2014, to inform future policies for a healthier nation. METHODS: Food and health data were obtained through Food Balance Sheets, Malaysian Adult Nutrition Survey (MANS) and National Health and Morbidity Surveys (NHMS) for year-to-year review. Interaction between changes in food supplies and dietary trends and the progression of diet-related diseases and risk factors in tandem with demographic and socioeconomic transitions were observed using quasi-historical approach. RESULTS: The period-under-review has seen Malaysia becoming more affluent, urbanised and modernised. Energy supply for Malaysian population remained consistently in excess of average calorie needs by a minimum of 30%. There were significant signs of shifting food trends, particularly in the supply of wheat (+ 56.5%), rice (- 23.7%), sugar and sweeteners (+ 23.9%), meat (+ 49.3%), fish and seafood (+ 38.7%), and eggs (+ 55.7%). The plant/animal protein ratio has decreased over time. Prevalence of NCD and associated risk factors has increased rapidly, some as high as 170%, despite various policy efforts to reduce them. CONCLUSION: The study highlights the importance of policymakers taking a relook into its policies and strategies, and formulate sustainable, comprehensive and multifaceted actions together with all relevant stakeholders to ensure a conducive, healthy and nutritious food systems and environment for its population.

Identification of Education Models to Improve Health Outcomes in Arab Women with Pre-Diabetes.

Few evaluations of interventions to delay or prevent type 2 diabetes mellitus (T2DM) in Saudi Arabia (SA) have been undertaken. The present study evaluates the impact of a 6-month intensive lifestyle modification intervention delivered in primary care. Females from SA with prediabetes, aged 18-55 years, were recruited with 190 participants eligible following screening and randomly allocated to receive a 3-month one-on-one, intensive lifestyle modification (intervention group (IG) n = 95) or standard guidance (control group (CG) n = 95). Participants completed questionnaires including demographic, dietary and physical activity data. Blood samples were collected at baseline, 3 and 6 months. A total of 123 (74 IG (age 40.6 ± 9.8 years; body mass index (BMI) 31.2 ± 7.0 kg/m2) and 49 CG (age 40.6 ± 12.7 years; BMI 32.3 ± 5.4 kg/m2)) participants completed the study. After 6 months, haemoglobin A1c (HbA1c; primary endpoint) significantly improved in the IG than CG completers in between-group comparisons (p < 0.001). Comparison between groups showed significant improvements in overall energy intake, total and high density lipoprotein (HDL)-cholesterol in favour of IG (p-values < 0.001, 0.04 and <0.001, respectively). BMI and weight change were not clinically significant in between group comparisons. A 6-month, intense one-on-one intervention in lifestyle modification significantly improves glycaemic and cardio metabolic profile of females living in SA with pre-diabetes delivered in a primary care setting. Longer duration studies, using the same intervention, may determine whether a meaningful weight loss secondary to improved diet can be achieved.

The Impact of Dairy Protein Intake on Muscle Mass, Muscle Strength, and Physical Performance in Middle-Aged to Older Adults with or without Existing Sarcopenia: A Systematic Review and Meta-Analysis.

Sarcopenia is an age-related condition associated with a progressive loss of muscle mass and strength. Insufficient protein intake is a risk factor for sarcopenia. Protein supplementation is suggested to improve muscle anabolism and function in younger and older adults. Dairy products are a good source of high-quality proteins. This review evaluates the effectiveness of dairy proteins on functions associated with sarcopenia in middle-aged and older adults. Randomized controlled trials were identified using PubMed, CINAHL/EBSCO, and Web of Science databases (last search: 10 May 2017) and were quality assessed. The results of appendicular muscle mass and muscle strength of handgrip and leg press were pooled using a random-effects model. The analysis of the Short Physical Performance Battery is presented in narrative form. Adverse events and tolerability of dairy protein supplementation were considered as secondary outcomes. Fourteen studies involving 1424 participants aged between 61 and 81 y met the inclusion criteria. Dairy protein significantly increased appendicular muscle mass (0.13 kg; 95% CI: 0.01, 0.26 kg; P = 0.04); however, it had no effect on improvement in handgrip (0.84 kg; 95% CI: -0.24, 1.93 kg; P = 0.13) or leg press (0.37 kg; 95% CI: -4.79, 5.53 kg; P = 0.89). The effect of dairy protein on the Short Physical Performance Battery was inconclusive. Nine studies reported the dairy protein to be well tolerated with no serious adverse events. Although future high-quality research is required to establish the optimal type of dairy protein, the present systematic review provides evidence of the beneficial effect of dairy protein as a potential nutrition strategy to improve appendicular muscle mass in middle-aged and older adults.

Associations between children's diet quality and watching television during meal or snack consumption: A systematic review.

Studies have identified an association between watching television (TV) and childhood obesity. This review adds context to existing research by examining the associations between TV viewing, whilst eating, and children's diet quality. Web of Science and PubMed databases were searched from January 2000 to June 2014. Cross-sectional trials of case control or cohort studies, which included baseline data, measuring the associations between eating whilst watching TV and children's food and drink intake. Quality of selected papers was assessed. Thirteen studies, representing 61,674 children aged 1-18 yrs, met inclusion criteria. Of six studies reporting overall food habits, all found a positive association between TV viewing and consumption of pizza, fried foods, sweets, and snacks. Of eight studies looking at fruit and vegetable consumption, seven identified a negative association with eating whilst watching TV (p < .0001). Four out of five studies identified a positive association between watching TV whilst eating and servings of sugar-sweetened beverages (p < .0001). Four studies identified an association between low socioeconomic status and increased likelihood of eating whilst watching TV (p ≤ .01). Family meals did not overcome the adverse impact on diet quality of having the TV on at mealtimes. Eating whilst watching television is associated with poorer diet quality among children, including more frequent consumption of sugar-sweetened beverages and high-fat, high-sugar foods and fewer fruits and vegetables. Although these differences in consumption are small, the cumulative effect may contribute to the positive association between eating whilst watching TV and childhood obesity.

Socio-economic and behavioural determinants of fruit and vegetable intake in Moroccan women.

OBJECTIVE: To estimate daily fruit and vegetable intakes and to investigate socio-economic and behavioural differences in fruit and vegetable consumption among urban Moroccan women. DESIGN: A cross-sectional survey. Fruit and vegetable intake was measured with a single 24 h recall. SETTINGS: A representative population-based survey conducted in the area of Rabat-Salé. SUBJECTS: Women (n 894) of child-bearing age (20-49 years). RESULTS: Mean fruit and vegetable intake was 331 g/d (155 g/d for fruit and 176 g/d for vegetables). Only one-third (32.1 %) of women consumed ≥ 400 g/d and half the sample (50.6 %) were considered as low consumers, i.e. <280 g/d. Women of higher economic status ate significantly more fruit (P<0.05) and more fruit and vegetables combined (P<0.05). Women ate significantly less vegetables if they ate out of home more often or skipped at least one main meal (breakfast, lunch or dinner) or ate more processed foods (P<0.05, P<0.01 and P<0.001, respectively). Fruit and vegetable diversity was not associated with any of the factors investigated. CONCLUSIONS: In this population, fruit and vegetable intakes are driven by different determinants. Indeed, while vegetable consumption was related only to behavioural determinants, fruit consumption was influenced only by economic status. Therefore, programmes promoting fruit and vegetable intake would be more effective if they account for these specific determinants in their design.

Spatial and rainfall related patterns of bacterial contamination in Sydney Harbour estuary.

Water quality in recreational areas in Sydney Harbour, Australia, was analysed first to identify spatial patterns in faecal coliform and enterococci densities, and then to determine the relationship between bacterial densities and catchment rainfall. Non-metric multidimensional scaling separated sites closest to the mouth of the harbour from those further up the harbour's west and north-west arms. Sites closest to the harbour mouth generally had lower frequencies of high bacterial densities that exceeded median water quality guideline values. We attribute this to greater tidal flushing at sites closer to the harbour mouth. Eight site groups were identified within the harbour. Within each group, multiple regression analyses indicated rainfall accounted for between 15 and 66% of the variability in the bacterial densities. Variation in bacterial densities explained by rainfall was lower for sites closer to the harbour mouth where tidal flushing is greatest. Thus, our findings indicate that simple rainfall-based regression models are appropriate for predicting bacterial concentrations when flushing at a site is limited. More complex models incorporating a suite of environmental variables may improve the ability to predict bacterial concentrations at well-flushed sites, but even then, their predictive ability may be low.
