INTRODUCTION
The aim of the study was to identify available polycystic ovary syndrome (PCOS) models of care (MoCs) and describe their characteristics and alignment with the international PCOS guideline.
METHODS
Ovid MEDLINE, All EBM, PsycINFO, Embase, and CINAHL were searched from inception until 11 July 2022. Any study with a description of a PCOS MoC was included. Non-evidence-based guidelines, abstracts, study protocols, and clinical trial registrations were excluded. We also excluded MoCs delivered in research settings to minimize care bias. Meta-analysis was not performed due to heterogeneity across MoCs. We describe and evaluate each MoC based on the recommendations made by the international evidence-based guideline for assessing and managing PCOS.
RESULTS
Of 3,671 articles, six articles describing five MoCs were included in our systematic review. All MoCs described a multidisciplinary approach, including an endocrinologist, dietitian, gynecologist, psychologist, dermatologist, etc. Three MoCs described all aspects of PCOS care aligned with the international guideline recommendations. These include providing education on long-term risks, lifestyle interventions, screening and management of emotional well-being, cardiometabolic diseases, and the dermatological and reproductive elements of PCOS. Three MoCs evaluated patients' and healthcare professionals' satisfaction, with generally positive findings. Only one MoC explored the impact of their service on patients' health outcomes and showed improvement in BMI.
CONCLUSION
There is limited literature describing PCOS MoCs in routine practice. Future research should explore developing cost-effective co-created multidisciplinary PCOS MoCs globally. This may be facilitated by the exchange of best practices between institutions with an established MoC and those who are interested in setting one up.

Arab countries are doubly burdened with undernutrition as well as overweight and obesity. To provide guidance to those looking to address concerns of obesity and overweight among children in this region, the current review bridges an existing knowledge gap and systematically characterizes and evaluates the available scientific evidence pertaining to school-based nutrition interventions completed to date across the Arab world. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and relevant keywords, terms and phrases, a search of the literature across 14 databases for school-based nutrition interventions implemented in this region was conducted. Out of 1568 articles from 14 databases, 38 full-text articles meeting the inclusion criteria were retrieved. Further assessment for eligibility excluded 23 articles and included one article from hand-searching references, leaving 16 articles in the final analysis. Most articles (n = 7) with the implementation of 5 months or longer found strong positive and significant impacts on limiting sweets consumption, increased dietary knowledge, self-efficacy, breakfast and fruit and vegetable consumption, among others. We also found evidence (n = 5) that teachers trained by experts such as dietitians and pediatricians can effectively implement nutrition interventions that achieve the intended outcomes. Training teachers to implement theory-based nutrition and health promotion curricula serves as a potential solution to improving nutrition knowledge, health behaviors and dietary practices among children living in Arab countries. Appropriately designed and implemented nutrition interventions can positively impact nutrition knowledge, health and diet-related behaviors in children and adolescents in this region.

Effectiveness of Gardening-Only, Cooking-Only and Combined Cooking and Gardening Programs in Elementary Schools to Improve Fruit and Vegetable Intake: A Systematic Review.
The objective is to compare the gardening, cooking, and combined cooking and gardening programs in elementary schools from the past decade (2011-2022) in improving six psychosocial and behavioral outcomes related to fruit and vegetable intake. This review was conducted following the PRISMA guidelines. Five scientific databases were searched to identify 4763 potential articles, 44 articles were retained after screening the studies' abstract, and 36 articles were included after further investigation into each intervention. This review included 9 gardening-only programs, 8 cooking-only programs, and 19 combined cooking and gardening programs. The included studies were from 14 different countries with half of these studies took place in the United States ( = 18). Of the outcomes assessed, 100% (10/10) of the studies were effective in improving knowledge/skills, 90% effective in improving attitudes and self-efficacy to consume F and V (9/10), 80% produced significant results for gardening and cooking attitudes/behaviors (8/10) and willingness to try F and V (4/5), 68% (11/16) programs resulted in increase in F and V intake, and 62% (10/16) programs improved F and V preference. This review suggests that gardening-only programs (89%) and cooking-only programs (88%) were slightly more effective in producing significant findings compared to combined programs (84%), but more high-quality interventions are needed to confirm these findings.

This scoping review mapped literature available on Canadian dietetics, nutrition, and foods students' and graduates' interaction(s) with simulation-based education (SBE) during undergraduate and/or practicum. One certified Librarian led the preliminary search (Summer, 2021), while three Joanna Briggs Institute-trained reviewers conducted the comprehensive search via MEDLINE (OVID), CINAHL (EBSCO), Academic Search Premier (EBSCO), Embase (Elsevier), Scopus (Elsevier), and Google (February 2022). A data extraction tool designed specifically for the study objectives and research inclusion criteria was used. We recorded 354 results and included 7. Seven types of SBE were recorded: () comprehensive care plan (n = 2); () nutritional diagnosis/assessment (n = 2); () body composition assessment (n = 1); () introducing patient to dysphagia care (n = 1); () nutrition counselling session (n = 1); () nutrition-focused physical examination (n = 1); and () professional communications via social media (n = 1). Results indicate that Canadian dietitian-led SBE includes the use of simulated patients, nutritional diagnosis/assessment, and the creation of comprehensive care plans, among others. Students have been assessed for performance of trained tasks through exams, self-awareness surveys, and interviews, and SBE activities have been evaluated for effectiveness through questionnaires and interviews with users/students. Canadian literature is limited, and more can be learned by exploring the global context within and outside the profession.

Maternal diet during pregnancy can have a significant impact on maternal and offspring health. As nutrition counselling is an important component of prenatal care, registered dietitians (RDs) are uniquely trained professionals who can provide personalized nutrition counselling customized to an individual's sociocultural needs. The objective of this systematic review was to determine if RD involvement during pregnancy is associated with a lower prevalence of adverse birth outcomes in the United States and Canada. The review was conducted through a search of four databases: PubMed, CINAHL, Embase, and Web of Science. A total of 14 studies were identified. Women had a lower prevalence of low birth weight and preterm infants when RDs were involved during prenatal care. While RD involvement during pregnancy was not associated with macrosomia, more research is needed to assess its relationship with small for gestational age, large for gestational age, and infant mortality. Future research should also investigate the specific dietary advice provided by RDs and the extent and timing of their involvement throughout pregnancy to better understand the mechanisms surrounding nutrition counselling, in utero development, and health outcomes.

Review
OBJECTIVES
Health systems worldwide are faced with the challenge of adequately staffing their hospital services. Much of the current research and subsequent policy has been focusing on nurse staffing and minimum ratios to ensure quality and safety of patient care. Nonetheless, nurses are not the only profession who interact with patients, and, therefore, not the only professional group who has the potential to influence the outcomes of patients while in hospital. We aimed to synthesise the evidence on the relationship between multi-disciplinary staffing levels in hospital including nursing, medical and allied health professionals and the risk of death.
METHODS
Systematic review. We searched Embase, Medline, CINAHL, and the Cochrane Library for quantitative or mixed methods studies with a quantitative component exploring the association between multi-disciplinary hospital staffing levels and mortality.
RESULTS
We included 12 studies. Hospitals with more physicians and registered nurses had lower mortality rates. Higher levels of nursing assistants were associated with higher patient mortality. Only two studies included other health professionals, providing scant evidence about their effect.
CONCLUSIONS
Pathways for allied health professionals such as physiotherapists, occupational therapists, dietitians, pharmacists, to impact safety and other patient outcomes are plausible and should be explored in future studies.

Nutrition-Related N-of-1 Studies Warrant Further Research to Provide Evidence for Dietitians to Practice Personalized (Precision) Medical Nutrition Therapy: A Systematic Review.
N-of-1 trials provide a higher level of evidence than randomized controlled trials for determining which treatment works best for an individual, and the design readily accommodates testing of personalized nutrition. The aim of this systematic review was to synthesize nutrition-related studies using an N-of-1 design. The inclusion criterion was adult participants; the intervention/exposure was any nutrient, food, beverage, or dietary pattern; the comparators were baseline values, a control condition untreated or placebo, or an alternate treatment, alongside any outcomes such as changes in diet, body weight, biochemical outcomes, symptoms, quality of life, or a disease outcome resulting from differences in nutritional conditions. The information sources used were Medline, Embase, Scopus, Cochrane Central, and PsychInfo. The quality of study reporting was assessed using the Consort Extension for N-of-1 trials (CENT) statement or the STrengthening Reporting of OBservational Studies in Epidemiology (STROBE) guidelines, as appropriate. From 211 articles screened, a total of 7 studies were included and were conducted in 5 countries with a total of 83 participants. The conditions studied included prediabetes, diabetes, irritable bowel syndrome, weight management, and investigation of the effect of diet in healthy people. The quality of reporting was mostly adequate, and dietary assessment quality varied from poor to good. The evidence base is small, but served to illustrate the main characteristics of N-of-1 study designs and considerations for moving research forward in the era of personalized medical nutrition therapy.

Meta-Analysis
There has been an emerging concern that non-nutritive sweeteners (NNS) can increase the risk of cardiometabolic disease. Much of the attention has focused on acute metabolic and endocrine responses to NNS. To examine whether these mechanisms are operational under real-world scenarios, we conducted a systematic review and network meta-analysis of acute trials comparing the effects of non-nutritive sweetened beverages (NNS beverages) with water and sugar-sweetened beverages (SSBs) in humans. MEDLINE, EMBASE, and The Cochrane Library were searched through to January 15, 2022. We included acute, single-exposure, randomized, and non-randomized, clinical trials in humans, regardless of health status. Three patterns of intake were examined: (1) uncoupling interventions, where NNS beverages were consumed alone without added energy or nutrients; (2) coupling interventions, where NNS beverages were consumed together with added energy and nutrients as carbohydrates; and (3) delayed coupling interventions, where NNS beverages were consumed as a preload prior to added energy and nutrients as carbohydrates. The primary outcome was a 2 h incremental area under the curve (iAUC) for blood glucose concentration. Secondary outcomes included 2 h iAUC for insulin, glucagon-like peptide 1 (GLP-1), gastric inhibitory polypeptide (GIP), peptide YY (PYY), ghrelin, leptin, and glucagon concentrations. Network meta-analysis and confidence in the network meta-analysis (CINeMA) were conducted in R-studio and CINeMA, respectively. Thirty-six trials involving 472 predominantly healthy participants were included. Trials examined a variety of single NNS (acesulfame potassium, aspartame, cyclamate, saccharin, stevia, and sucralose) and NNS blends (acesulfame potassium + aspartame, acesulfame potassium + sucralose, acesulfame potassium + aspartame + cyclamate, and acesulfame potassium + aspartame + sucralose), along with matched water/unsweetened controls and SSBs sweetened with various caloric sugars (glucose, sucrose, and fructose). In uncoupling interventions, NNS beverages (single or blends) had no effect on postprandial glucose, insulin, GLP-1, GIP, PYY, ghrelin, and glucagon responses similar to water controls (generally, low to moderate confidence), whereas SSBs sweetened with caloric sugars (glucose and sucrose) increased postprandial glucose, insulin, GLP-1, and GIP responses with no differences in postprandial ghrelin and glucagon responses (generally, low to moderate confidence). In coupling and delayed coupling interventions, NNS beverages had no postprandial glucose and endocrine effects similar to controls (generally, low to moderate confidence). The available evidence suggests that NNS beverages sweetened with single or blends of NNS have no acute metabolic and endocrine effects, similar to water. These findings provide support for NNS beverages as an alternative replacement strategy for SSBs in the acute postprandial setting.

Review
Head and neck cancer (HNC) is associated with high rates of malnutrition. We conducted a systematic review and descriptive analysis to determine the effects of nutrition interventions on the nutrition status, quality of life (QOL), and treatment tolerance of HNC patients. PubMed, Web of Science, and Embase were searched to include all potentially relevant studies published between 2006-2022. Meta-analysis was not conducted due to heterogeneity of study designs and outcomes reported. Studies were categorized as nutrition interventions: (1) with oral nutrition supplements (ONS) and medical nutrition therapy (MNT) delivered by an RD; (2) with enteral nutrition (EN) support and MNT delivered by an RD; (3) with motivational interviewing and no ONS or EN; and (4) with ONS and no RD. Seven articles met inclusion criteria. Studies measured outcomes from immediately following treatment to 12 months post-treatment. Interventions resulted in benefits to lean mass/weight maintenance (three studies), QOL (two studies), nutrient intake adequacy (one study) and treatment tolerance (two studies). Nutrition counseling by a registered dietitian leads to improved nutrition status and QOL. Further research is needed to determine best practices related to timing of initiation, duration of nutrition intervention, as well as frequency of dietitian follow-up.

Review
BACKGROUND AND AIMS
Patients' nutritional intake is a crucial issue in modern hospitals, where the high prevalence of disease-related malnutrition may worsen clinical outcomes. On the other hand, food waste raises concerns in terms of sustainability and environmental burden. We conducted a systematic review to ascertain which hospital services could overcome both issues.
METHODS
A systematic literature search following PRISMA guidelines was conducted across MEDLINE, Web of Science, and Scopus for randomised controlled trials (RCTs) and observational studies comparing the effect of hospital strategies on energy intake, protein intake, and plate/food waste. The quality of included studies was assessed using the Newcastle-Ottawa Scale for cohort studies and the Cochrane Risk of Bias tool from the Cochrane Handbook for Systematic Reviews of Interventions for RCTs.
RESULTS
Nineteen studies were included, assessing as many hospital strategies such as food service systems-including catering and room service-( = 9), protected mealtimes and volunteer feeding assistance ( = 4), food presentation strategies ( = 3), nutritional counseling and education ( = 2), plant-based proteins meal ( = 1). Given the heterogeneity of the included studies, the results were narratively analysed.
CONCLUSIONS
Although the results should be confirmed by prospective and large sample-size studies, the personalisation of the meal and efficient room service may improve nutritional intake while decreasing food waste. Clinical nutritionist staff-especially dietitians-may increase food intake reducing food waste through active monitoring of the patients' nutritional needs.
