Review
AIM
Scientific evidence underpins dietetics practice; however, evidence of how the therapeutic relationship influences outcomes is limited. This integrative review aims to provide a comprehensive overview of the topic of the therapeutic relationship between clients and dietitians in the individual counselling context by summarising empirical literature into qualitative themes.
METHODS
An electronic literature search of the Cumulative Index of Nursing and Allied Health Literature, PsychInfo, Scopus and Web of Science databases was conducted in October 2018 and repeated in February 2021. Studies were included if they explicitly referred to the therapeutic relationship (or associated terms), were based on study data and available in full text. Extracted data were checked by a second researcher and the methodological quality was evaluated independently by two researchers using the Mixed Methods Appraisal Tool. An iterative process of qualitatively coding, categorising and comparing data to examine recurring themes was applied.
RESULTS
Seventy-six studies met the inclusion criteria. Five themes were identified which showed the extent and nature of research in this area. Studies revealed the therapeutic relationship: (i) is valued within clinical dietetic practice, (ii) involves complex and multifactorial interactions, (iii) is perceived as having a positive influence, (iv) requires skills training and (v) is embedded in practice models and tools.
CONCLUSION
Studies show the therapeutic relationship is a valued and multifactorial component of clinical dietetic practice and is perceived to positively influence the client and dietitian. Observational data are needed to assess the extent to which the strength of the therapeutic relationship might contribute to clients' health outcomes.

Review
BACKGROUND
Nutrigenomics - the study of the interactions between genetics and nutrition - has emerged as a pivotal field in personalized nutrition. Among various genetic variations, single-nucleotide polymorphisms (SNPs) have been extensively studied for their probable relationship with metabolic traits.
METHODS
Throughout this review, we have employed a targeted research approach, carefully handpicking the most representative and relevant articles on the subject. Our methodology involved a systematic review of the scientific literature to ensure a comprehensive and accurate overview of the available sources.
RESULTS
SNPs have demonstrated a significant influence on lipid metabolism, by impacting genes that encode for enzymes involved in lipid synthesis, transport, and storage. Furthermore, they have the ability to affect enzymes in glycolysis and insulin signaling pathways: in a way, they can influence the risk of type 2 diabetes. Thanks to recent advances in genotyping technologies, we now know numerous SNPs linked to lipid and carbohydrate metabolism. The large-scale studies on this topic have unveiled the potential of personalized dietary recommendations based on an individual's genetic makeup. Personalized nutritional interventions hold promise to mitigate the risk of various chronic diseases; however, translating these scientific insights into actionable dietary guidelines is still challenging.
CONCLUSIONS
As the field of nutrigenomics continues to evolve, collaborations between geneticists, nutritionists, and healthcare providers are essential to harness the power of genetic information for improving metabolic health. By unraveling the genetic basis of metabolic responses to diet, this field holds the potential to revolutionize how we approach dietary recommendations and preventive healthcare practices.

Review
Avoidant/Restrictive food intake disorder (ARFID) is a feeding disorder characterized by persistent difficulty eating, such as limited choices of preferred foods, avoidance or restriction of certain foods or food groups, and negative emotions related to eating or meals. Although ARFID mainly affects children, it can also occur in adolescents and adults. ARFID can have serious physical and mental health consequences, including stunted growth, nutritional deficiencies, anxiety, and other psychiatric comorbidities. Despite its increasing importance, ARFID is relatively underrecognized and undertreated in clinical practice. Treatment consists of a multidisciplinary approach involving pediatric gastroenterologists, nutritionists, neuropsychiatrists, and psychologists. However, there are several gaps in the therapeutic approach for this condition, mainly due to the lack of interventional trials and the methodological variability of existing studies. Few studies have explored the nutritional management of ARFID, and no standardized guidelines exist to date. We performed a systematic literature review to describe the different nutritional interventions for children and adolescents diagnosed with ARFID and to assess their efficacy and tolerability. We identified seven retrospective cohort studies where patients with various eating and feeding disorders, including ARFID, underwent nutritional rehabilitation in hospital settings. In all studies, similar outcomes emerged in terms of efficacy and tolerability. According to our findings, the oral route should be the preferred way to start the refeeding protocol, and the enteral route should be generally considered a last resort for non-compliant patients or in cases of clinical instability. The initial caloric intake may be adapted to the initial nutritional status, but more aggressive refeeding regimens appear to be well tolerated and not associated with an increased risk of clinical refeeding syndrome (RS). In severely malnourished patients, however, phosphorus or magnesium supplementation may be considered to prevent the risk of electrolyte imbalance, or RS.

Review
AIM
An understanding of effective foodservice interventions on nutrition outcomes in adult patients with cancer is required to support clinical decision making. This systematic review aimed to determine the effect of foodservice interventions across a range of nutritional outcomes and satisfaction of hospitalised and ambulatory adult oncology patients.
METHODS
The review protocol was registered with PROSPERO (CRD42016045772). Six databases were searched using search terms associated with the intervention and population. No date or language restrictions were applied. Authors applied the inclusion criteria to titles and abstracts and then full-text papers. The final library was assessed for risk of bias. Outcome data were combined narratively and, where possible, by meta-analysis.
RESULTS
From the title and abstract review of 4414 studies, 12 studies testing the effect of foodservice interventions were included in this review. Meta-analyses demonstrated significantly greater energy (mean difference 1.54 MJ/day; 95% CI 0.85-2.23 MJ/day) and protein (mean difference 18.98 g/day; 95% CI 11.58-26.39 g/day) intake through the addition of oral nutrition supplements. Other positive effects on anthropometric outcomes were also recorded. Patient satisfaction was enhanced through other foodservice interventions.
CONCLUSIONS
Limited original research was found exploring the effect of foodservice interventions in oncology patients. Significant findings were found in favour of the intervention across a range of nutritional outcomes, suggesting that foodservice interventions may improve clinical outcomes and satisfaction in this population. Effective foodservice interventions for oncology patients remain under-researched, so we encourage dietitians and foodservice staff to implement rigorous study designs to evaluate and publish interventions in this clinical group.

Review
BACKGROUND
Nutrition informatics has become a novel approach for registered dietitians to practice in this field and make a profit for health care. Recommendation systems considered as an effective technology into aid users to adjust their eating behavior and achieve the goal of healthier food and diet. The purpose of this study is to review nutrition recommendation systems (NRS) and their characteristics for the first time.
MATERIAL AND METHODS
The systematic review was conducted using a comprehensive selection of scientific databases as reference sources, allowing access to diverse publications in the field. The process of articles selection was based on the PRISMA strategy. We identified keywords from our initial research, MeSH database and expert's opinion. Databases of PubMed, Web of Sciences, Scopus, Embase, and IEEE were searched. After evaluating, they obtained records from databases by two independent reviewers and inclusion and exclusion criteria were applied to each retrieved work to select those of interest. Finally, 25 studies were included.
RESULTS
Hybrid recommender systems and knowledge-based recommender systems with 40% and 32%, respectively, were the mostly recommender types used in NRS. In NRS, rule-based and ontology techniques were used frequently. The frequented platform that applied in NRS was a mobile application with 28%.
CONCLUSION
If NRS was properly designed, implemented and finally evaluated, it could be used as an effective tool to improve nutrition and promote a healthy lifestyle. This study can help to inform specialists in the nutrition informatics domain, which was necessary to design and develop NRS.

Review
OBJECTIVES
To identify, appraise, and describe studies focussing on the nutritional characteristics of people experiencing homelessness (PEH).
STUDY DESIGN
Systematic (narrative) review.
METHODS
We identified full-text studies of any design and in the English language of adults (≥18 years) fulfilling the European Typology criteria for homelessness, based in community or hospital settings, and which report nutritional measures. Five electronic databases, 13 grey literature sources, reference lists, and forward citations were searched. Data on study characteristics and nutrition measures were collected and synthesised narratively. Risk of bias was assessed using relevant checklists for each study type.
RESULTS
A total of 1130 studies were identified and retrieved. After screening, six studies were included for review: three cross-sectional studies; two case-control studies; and one randomised control trial, involving a total of 1561 participants from various settings including shelters, drop-in centres, hospitals, and hostels. All included studies were from high-income countries. Studies reported a range of nutrition measures including anthropometry (e.g., body mass index (BMI)), serum micronutrients and biomarkers, and dietary intake. Between 33.3% and 68.3% of participants were overweight or obese; 3.5%-17% were underweight; and low blood levels of iron, folate, vitamins C, D, and B12, and haemoglobin were prevalent. PEH consumed high amounts of dietary fats and alcohol, and low amounts of fruits and vegetables compared with national guidelines and housed individuals. There was moderate to high risk of selection and measurement bias and confounding in included studies.
CONCLUSIONS
A majority of PEH are within unhealthy BMI ranges and are deficient in serum micronutrients and nutritional biomarkers. Studies using large data sets that examine multiple aspects of nutrition are needed to describe the nutritional characteristics of PEH.
REGISTRATION
This systematic review is based on a prespecified protocol registered with the International Prospective Register of Systematic Reviews (PROSPERO CRD42021218900).

Review
BACKGROUND
A suitably prepared and qualified nutrition and dietetics workforce is part of the solution to combating the burden of disease. Competency-based assessment is a key part of the education of future workforces. Although there has been recent attention on competency-based assessment in dietetics, there is little exploration of competency-based education for the preparation of nutritionists. The present study aimed to understand how competency-based assessment is implemented and evaluated in nutrition education.
METHODS
A systematic literature review was carried out according to PRISMA guidelines. Four databases were initially searched in February 2020 using key words related to competenc* in combination with nutrition or dietetic and their synonyms. An updated search was completed again in March 2021. Studies that met eligibility criteria where the focus was on nutrition and involved a method of competency-based assessment were synthesised narratively.
RESULTS
From a total of 6262 titles and abstracts, six studies on competency assessment in nutrition education were identified. The assessments focused on the development of key skills, including motivational interviewing and nutrition assessment, changes to knowledge and attitudes on food and culture, and self-perceived development of communication, collaboration, management, advocacy, scholarship and professional capabilities. No studies were found that assessed promotion of health and wellbeing or the food chain competencies.
CONCLUSIONS
The lack of research in competency-based assessment must be addressed to ensure we are effectively preparing future nutritionists for work such that they can impact health outcomes.

Impact of Nutrition and Physical Activity Interventions Provided by Nutrition and Exercise Practitioners for the Adult General Population: A Systematic Review and Meta-Analysis.
Healthy dietary intake and physical activity reduce the risk of non-communicable diseases. This systematic review and meta-analysis aimed to examine the effect of interventions including both nutrition and physical activity provided by nutrition and exercise practitioners for adults in the general population (those without diagnosed disease). The MEDLINE, CINAHL, Cochrane Central, Cochrane Database of Systematic Reviews and SportDiscus databases were searched for randomized controlled trials (RCTs) published from 2010 until April 2021. Outcomes included physical activity, fruit and vegetable intake, waist circumference, percent weight loss, quality of life (QoL) and adverse events. Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods were used to synthesize and grade evidence. Meta-analyses were stratified according to participant health status. The database search identified 11,205 articles, and 31 RCTs were included. Interventions increased physical activity amount [standardized mean difference (SMD) (95% CI): 0.25 (0.08, 0.43)] (low certainty evidence); increased vegetable intake [SMD (95% CI): 0.14 (0.05, 0.23)] (moderate certainty evidence); reduced waist circumference [MD (95% CI): -2.16 cm (-2.96, -1.36)] (high certainty evidence); and increased likelihood of achieving 5% weight loss for adults with overweight and obesity [relative risk (95% CI): 2.37 (1.76, 3.19)] (high certainty evidence). Very low and low certainty evidence described little-to-no effect on QoL or adverse events. Nutrition and exercise practitioners play key roles in facilitating positive lifestyle behaviors to reduce cardiometabolic disease risk in adults.

Meta-Analysis Review
AIM
Negative attitudes towards people with obesity are common even in health care settings. So far, the attitudes and causal beliefs of dietitians and nutritionists have not been investigated systematically. The aim of this article was to review the current state of quantitative research on weight-related stigma by dietitians and nutritionists.
METHOD
A systematic literature review was conducted in 2014 using PubMed, PsycINFO, Web of Science and Cochrane Library.
RESULTS
Eight studies were found that differ in regard to study characteristics, instruments and the origin of the sample. Six out of eight studies reported weight stigma expressed by dietitians and nutritionists. Their believed causes of obesity indicated a defined preference for internal factors rather than genetics or biology.
DISCUSSION
Results of studies were not homogenous. The degree of negative attitudes by dietitians and nutritionists towards people with obesity appeared to be slightly less pronounced compared to the general public and other health care professionals. Stigma and its consequences should be included into educational programs to optimally prepare dietitians and nutritionists.

Meta-Analysis Review
OBJECTIVE
To review recent published trials of nutrition and dietary interventions for people with serious mental illness; to assess their effectiveness in improving metabolic syndrome risk factors.
STUDY DESIGN
Systematic review and meta-analysis of randomised and non-randomised controlled trials of interventions with a nutrition/diet-related component delivered to people with serious mental illness, published 1 January 2010 - 6 September 2021. Primary outcomes were weight, body mass index (BMI), and waist circumference. Secondary outcomes were total serum cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol, triglyceride, and blood glucose levels.
DATA SOURCES
MEDLINE, EMBASE, PsycINFO, CINAHL, and CENTRAL databases. In addition, reference lists of relevant publications were examined for further additional studies.
DATA SYNTHESIS
Twenty-five studies encompassing 26 intervention arms were included in our analysis. Eight studies were at low or some risk of bias, seventeen were deemed to be at high risk. Eight of seventeen intervention arms found statistically significant intervention effects on weight, ten of 24 on BMI, and seven of seventeen on waist circumference. The pooled effects of nutrition interventions on metabolic syndrome risk factors were statistically non-significant. However, we identified small size effects on weight for interventions delivered by dietitians (five studies; 262 intervention, 258 control participants; standardised mean difference [SMD], -0.28; 95% CI, -0.51 to -0.04) and interventions consisting of individual sessions only (three studies; 141 intervention, 134 control participants; SMD, -0.30; 95% CI, -0.54 to -0.06).
CONCLUSIONS
We found only limited evidence for nutrition interventions improving metabolic syndrome risk factors in people with serious mental illness. However, they may be more effective when delivered on an individual basis or by dietitians.
