A genomics perspective of personalized prevention and management of obesity.

This review discusses the landscape of personalized prevention and management of obesity from a nutrigenetics perspective. Focusing on macronutrient tailoring, we discuss the impact of genetic variation on responses to carbohydrate, lipid, protein, and fiber consumption. Our bioinformatic analysis of genomic variants guiding macronutrient intake revealed enrichment of pathways associated with circadian rhythm, melatonin metabolism, cholesterol and lipoprotein remodeling and PPAR signaling as potential targets of macronutrients for the management of obesity in relevant genetic backgrounds. Notably, our data-based in silico predictions suggest the potential of repurposing the SYK inhibitor fostamatinib for obesity treatment in relevant genetic profiles. In addition to dietary considerations, we address genetic variations guiding lifestyle changes in weight management, including exercise and chrononutrition. Finally, we emphasize the need for a refined understanding and expanded research into the complex genetic landscape underlying obesity and its management.

Proteomics in Patients with Fibromyalgia Syndrome: A Systematic Review of Observational Studies.

PURPOSE OF REVIEW: Fibromyalgia syndrome (FMS) is a disease of unknown pathophysiology, with the diagnosis being based on a set of clinical criteria. Proteomic analysis can provide significant biological information for the pathophysiology of the disease but may also reveal biomarkers for diagnosis or therapeutic targets. The present systematic review aims to synthesize the evidence regarding the proteome of adult patients with FMS using data from observational studies. RECENT FINDINGS: An extensive literature search was conducted in MEDLINE/PubMed, CENTRAL, and clinicaltrials.gov from inception until November 2022. The study protocol was published in OSF. Two independent reviewers evaluated the studies and extracted data. The quality of studies was assessed using the modified Newcastle-Ottawa scale adjusted for proteomic research. Ten studies fulfilled the protocol criteria, identifying 3328 proteins, 145 of which were differentially expressed among patients with FMS against controls. The proteins were identified in plasma, serum, cerebrospinal fluid, and saliva samples. The control groups included healthy individuals and patients with pain (inflammatory and non-inflammatory). The most important proteins identified involved transferrin, α-, ß-, and γ-fibrinogen chains, profilin-1, transaldolase, PGAM1, apolipoprotein-C3, complement C4A and C1QC, immunoglobin parts, and acute phase reactants. Weak correlations were observed between proteins and pain sensation, or quality of life scales, apart from the association of transferrin and a2-macroglobulin with moderate-to-severe pain sensation. The quality of included studies was moderate-to-good. FMS appears to be related to protein dysregulation in the complement and coagulation cascades and the metabolism of iron. Several proteins may be dysregulated due to the excessive oxidative stress response.

Serum Concentrations and Dietary Intake of Vitamin B12 in Children and Adolescents on Metformin: A Case-Control Study.

The International Society of Pediatric and Adolescent Diabetes (ISPAD) recommends metformin (MET) use for metabolic disturbances and hyperglycemia, either in combination with insulin therapy or alone. A caveat of MET therapy has been suggested to be biochemical vitamin B12 deficiency, as seen mainly in studies conducted in adults. In the present case-control study, children and adolescents of different weight status tiers on MET therapy for a median of 17 months formed the cases group (n = 23) and were compared with their peers not taking MET (n = 46). Anthropometry, dietary intake, and blood assays were recorded for both groups. MET group members were older, heavier, and taller compared with the controls, although BMI z-scores did not differ. In parallel, blood phosphorus and alkaline phosphatase (ALP) concentrations were lower in the MET group, whereas MCV, Δ4-androstenedione, and DHEA-S were higher. No differences were observed in the HOMA-IR, SHBG, hemoglobin, HbA1c, vitamin B12, or serum 25(OH)D3 concentrations between groups. Among those on MET, 17.4% exhibited vitamin B12 deficiency, whereas none of the controls had low vitamin B12 concentrations. Participants on MET therapy consumed less energy concerning their requirements, less vitamin B12, more carbohydrates (as a percentage of the energy intake), and fewer fats (including saturated and trans fats) compared with their peers not on MET. None of the children received oral nutrient supplements with vitamin B12. The results suggest that, in children and adolescents on MET therapy, the dietary intake of vitamin B12 is suboptimal, with the median coverage reaching 54% of the age- and sex-specific recommended daily allowance. This low dietary intake, paired with MET, may act synergistically in reducing the circulating vitamin B12 concentrations. Thus, caution is required when prescribing MET in children and adolescents, and replacement is warranted.

Temporomandibular joint disorders in seronegative spondyloarthritis: what a rheumatologist needs to know?

Temporomandibular joint (TMJ) can be affected in the context of spondyloarthritis (SpA) with detrimental impact on individuals' quality of life. Intra-articular inflammation, synovitis, enthesitis, disc displacement and cervical vertebrae malalignment are some of the pathophysiological phenomena involved. Temporomandibular joint disorders (TMD) incidence appears to be higher in patients with ankylosing spondylitis and psoriatic arthritis, especially when clinical evaluation includes not only imaging but relevant history, TMJ examination and diagnostic criteria for TMD. The Visual Analogue Scale (VAS) pain score and Health Assessment Questionnaire Disability Index (HAQ) quality of life score could be useful tools. Panoramic radiographs and ultrasound can be used for screening but in symptomatic patients magnetic resonance imaging (MRI) is preferable. Conservative management and early pharmacological treatment can prevent permanent joint impairment. For refractory cases, early referral to Legislation for Oral and Maxillofacial Surgery (OMFS) specialists is indicated. The aim of this narrative review is to address the involvement of TMJ in SpA and to encourage clinicians to incorporate TMJ assessment in their physical examination and basic screening.

Efficacy of n-3 fatty acid supplementation on rheumatoid arthritis' disease activity indicators: a systematic review and meta-analysis of randomized placebo-controlled trials.

Theoretical evidence and previous studies suggest that oralnutrient supplementation (ONS) with n-3 fatty acids for rheumatoid arthritis (RA) has the potential to lower disease activity indicators and non-steroidal anti-inflammatory drug (NSAID) uptake. A systematic search was conducted on five databases/registries from inception until May 23, 2021 with the aim to identify randomized placebo-controlled trials comparing n-3 supplements to placebo on disease-specific outcomes. A total of 23 studies matched the criteria (PROSPERO: CRD42019137041). Pooled analyses revealed that n-3 ONS provided a small effect in reducing pain [standardized mean difference (SMD): -0.16, 95% confidence intervals (CI): -0.40 to 0.09], and tender (SMD: -0.20, 95% CI: -0.46 to 0.05) and swollen joint count (SMD: -0.10, 95% CI: -0.28 to 0.07). In sensitivity analyses, there was a small effect in the reduction of NSAIDs intake (SMD: -0.22, 95% CI: -0.90 to 0.46), and c-reactive protein was reduced only by 0.21 mg/dL (95% CI: -0.75 to 0.33). Similar findings were observed regarding other objective/subjective outcomes. The certainty of the evidence was mostly of "very low/low" quality. Overall, n-3 ONS in RA might have a limited clinical benefit. Previous findings suggesting a reduction in NSAID intake may have been biased from the inadequate blinding of interventions.

A consensus document on definition and diagnostic criteria for orthorexia nervosa.

PURPOSE: Since the term orthorexia nervosa (ON) was coined from the Greek (ὀρθός, right and ὄρεξις, appetite) in 1997 to describe an obsession with "correct" eating, it has been used worldwide without a consistent definition. Although multiple authors have proposed diagnostic criteria, and many theoretical papers have been published, no consensus definition of ON exists, empirical primary evidence is limited, and ON is not a standardized diagnosis. These gaps prevent research to identify risk and protective factors, pathophysiology, functional consequences, and evidence-based therapeutic treatments. The aims of the current study are to categorize the common observations and presentations of ON pathology among experts in the eating disorder field, propose tentative diagnostic criteria, and consider which DSM chapter and category would be most appropriate for ON should it be included. METHODS: 47 eating disorder researchers and multidisciplinary treatment specialists from 14 different countries across four continents completed a three-phase modified Delphi process, with 75% agreement determined as the threshold for a statement to be included in the final consensus document. In phase I, participants were asked via online survey to agree or disagree with 67 statements about ON in four categories: A-Definition, Clinical Aspects, Duration; B-Consequences; C-Onset; D-Exclusion Criteria, and comment on their rationale. Responses were used to modify the statements which were then provided to the same participants for phase II, a second round of feedback, again in online survey form. Responses to phase II were used to modify and improve the statements for phase III, in which statements that met the predetermined 75% of agreement threshold were provided for review and commentary by all participants. RESULTS: 27 statements met or exceeded the consensus threshold and were compiled into proposed diagnostic criteria for ON. CONCLUSIONS: This is the first time a standardized definition of ON has been developed from a worldwide, multidisciplinary cohort of experts. It represents a summary of observations, clinical expertise, and research findings from a wide base of knowledge. It may be used as a base for diagnosis, treatment protocols, and further research to answer the open questions that remain, particularly the functional consequences of ON and how it might be prevented or identified and intervened upon in its early stages. Although the participants encompass many countries and disciplines, further research will be needed to determine if these diagnostic criteria are applicable to the experience of ON in geographic areas not represented in the current expert panel. LEVEL OF EVIDENCE: Level V: opinions of expert committees.

Tracing open data in emergencies: The case of the COVID-19 pandemic.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic constitutes an ongoing, burning Public Health Emergency of International Concern (PHEIC). In 2015, the World Health Organization adopted an open data policy recommendation in such situations. OBJECTIVES: The present cross-sectional meta-research study aimed to assess the availability of open data and metrics of articles pertaining to the COVID-19 outbreak in five high-impact journals. METHODS: All articles regarding the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), published in five high-impact journals (Ann Intern Med, BMJ, JAMA, NEJM and Lancet) until March 14, 2020 were retrieved. Metadata (namely the type of article, number of authors, number of patients, citations, errata, news and social media mentions) were extracted for each article in each journal in a systematic way. Google Scholar and Scopus were used for citations and author metrics respectively, and Altmetrics and PlumX were used for news and social media mentions retrieval. The degree of adherence to the PHEIC open data call was also evaluated. RESULTS: A total of 140 articles were published until March 14, 2020, mostly opinion papers. Sixteen errata followed these publications. The number of authors in each article ranged from 1 to 63, whereas the number of patients with a laboratory-confirmed SARS-CoV-2 infection reached 2645. Extensive hyperauthorship was evident among case studies. The impact of these publications reached a total of 4210 cumulative crude citations and 342 790 news and social media mentions. Only one publication (0.7%) provided complete open data, while 32 (22.9%) included patient data. CONCLUSIONS: Even though a large number of manuscripts was produced since the pandemic, availability of open data remains restricted.

Comparison of International Growth Standards for Assessing Nutritional Status in Cystic Fibrosis: The GreeCF Study.

OBJECTIVE: The aim of the study was to compare 3 international growth references and explore their differences in assessing growth in Greek school-aged patients with cystic fibrosis (CF). METHODS: Sample included 114 patients (50 boys, age 11.5 ±â€Š3.9 years), provided care at Aghia Sofia Children's Hospital, Greece. Anthropometrics and predicted forced expiratory volume in 1 second (FEV1%) were measured. Body mass index (BMI) and height z scores were computed according to the Centers for Disease Control and Prevention (CDC), World Health Organization (WHO), and International Obesity Task Force (IOTF) references. Agreement between methods was analyzed with kappa statistics, repeated-measures analysis of variance, and Bland-Altman analysis. The relationship between FEV1% and BMI was explored with linear regression. RESULTS: Mean CDC BMI z score was the lowest (0.06 ±â€Š1.08), followed by WHO (0.17 ±â€Š1.14) and IOTF (0.35 ±â€Š1.05) (P ≤ 0.001 for all). The CDC and WHO growth references highly agreed for most weight status strata and stunting; all other comparisons produced lower agreements. Except for CDC and IOTF BMI z scores, all other comparisons produced wide levels of agreement and proportional bias. CDC reference classified more children as attaining low or normal weight, against WHO or IOTF (P ≤ 0.001 for all). Lowest prevalence of ideal and excess weight was recorded by CDC, compared to all other standards (P ≤ 0.001 for all). All BMI z scores provided moderate associations with FEV1%. CONCLUSION: Large variations across weight status classification were present when employing 3 growth standards in school-aged patients . Given than BMI z-scores from all references provided comparable associations with pulmonary function, our data indicate that no studied reference is better than others in assessing growth in CF.

Effects of lunch club attendance on the dietary intake of older adults in the UK: A pilot cross-sectional study.

BACKGROUND: Lunch clubs are community-based projects where meals are offered with opportunities for social interaction, and a unique dining experience of dual commercial and communal nature. AIM: The aim of the present cross-sectional study was to assess differences in the dietary intake between lunch club and non-lunch club days among community-dwelling elderly, living in Dorset, UK. METHODS: A total of 39 elderly individuals attending local lunch clubs were recruited. Socioeconomic factors were recorded, anthropometric measurements were taken and the dietary intake was assessed in lunch club and non-lunch club days via 24 hour dietary recalls. RESULTS: For the majority of participants, having a hot meal (74.4%), meeting with friends (92.3%), dining outside home (76.9%), having a home-styled cooked meal (71.8%) and skipping cooking (43.6%) were considered as important factors for lunch club dining. Absolute energy intake, protein, fat, carbohydrate, saturated fatty acids, fibre, potassium, calcium, iron, vitamins A, C and folate and water from drinks were significantly greater on lunch club days. When intake was expressed as a percentage of the dietary reference values, all examined nutrients were consumed in greater adequacy during lunch club days, except potassium and vitamin D. CONCLUSIONS: Lunch clubs appear to be an effective means for ameliorating nutrient intake among older adults, while in parallel, offer the opportunity for socializing and sharing a hot meal with peers.

Exploring Patients' Experiences After Chronic Kidney Disease Diagnosis: A Qualitative Study.

Chronic kidney disease (CKD) diagnosis is often associated with stress, depression, and major lifestyle changes. The aim of this qualitative study was to explore patients' experiences of living with CKD. A non-random purposeful sampling strategy was used to recruit 10 patients with CKD undergoing hemodialysis, from a tertiary care hospital in Crete, Greece. Semi-structured, face-to-face interviews were conducted with open-ended questions aiming to assess different aspects of their life after CKD diagnosis. Four main themes were revealed portraying participants' experience, including facing a new reality, 2) confronting changes, 3) finding ways to cope, and 4) continuing life.

Nutrition Interventions in Pediatric Pancreatitis: Guidelines We Can Trust.

OBJECTIVE: Despite the fact that pediatric pancreatitis is an uncommon disease, its prevalence has increased in recent years. Nevertheless, until 4 years ago, the lack of nutritional guidelines for pediatric pancreatitis was evident, with all recommendations being based on clinical practice guidelines (CPGs) for adults. The aim of the present study was to review and critically appraise guidelines for the medical nutrition therapy (MNT) of pediatric pancreatitis. METHODS: A comprehensive search was performed in electronic databases (PubMed, Scopus, National Institute for Health and Care Excellence), the International Guidelines Network, BMJ best practice, and the Scottish Intercollegiate Guidelines Network to identify CPGs on the MNT of pediatric pancreatitis. The validated AGREE II tool was used for guidelines appraisal by a team of 3 independent multidisciplinary reviewers. RESULTS: A total of 4 CPGs were retrieved with pediatric pancreatitis MNT information. Out of the 4 advising bodies in total, the joint society paper published by the ESPGHAN/NASPGHAN received the highest score in almost all domains, whereas the Belgian consensus obtained the lowest score in all domains but stakeholder involvement, and was not recommended by 2 out of 3 reviewers. CONCLUSIONS: Pediatric pancreatitis guidelines appear heterogenous in quality, rigour, and transparency. Our study points out existing gaps and biases in the CPGs, and delineates the need for improving the domains identified as being of low-quality.

Sexual Dysfunction Among Young Men: Overview of Dietary Components Associated With Erectile Dysfunction.

BACKGROUND: Sexual dysfunction is relatively common in young men, presenting in diverse manifestations, including erectile dysfunction (ED), for which dietary modifications, including increased intake of dietary antioxidants, have been suggested as promising and cost-efficient approaches. AIM: To assess the consumption of selected dietary antioxidants, in particular flavonoids, in relation to ED symptoms in young men. METHODS: Men 18 to 40 years old were invited to complete an anonymous web-based questionnaire for this case-control study. ED was diagnosed with the International Index of Erectile Function (IIEF) and flavonoid intake was recorded using food-frequency questionnaires, with an emphasis on flavonoid-rich foods such as coffee, fruits, etc. Participants without ED (IIEF score ≥ 26; n = 264) formed the control group and those with ED (IIEF score < 26; n = 86) formed the case group. OUTCOMES: Dietary flavonoid intake. RESULTS: Men with ED reported a lower median monthly intake of total flavonoids (-2.18 g, 95% CI = -3.15 to -1.21, P < .001) and all flavonoid subclasses (P < .001) compared with controls. Adjustment of intake for age and body mass index showed that consumption of flavonoids 50 mg/day lowered the risk for ED by 32% (odds ratio = 0.68, 95% CI = 0.55-0.85, P < .001). Of all recorded flavonoids, flavones appeared to contribute the most to healthy erectile function. Controls reported a greater consumption of vegetables and fruits, a lower intake of dairy and alcoholic beverages, and a less intense smoking habit compared with cases (P < .001). CLINICAL IMPLICATIONS: Increased intake of fruits, vegetables, and flavonoids decreases the risk of ED in young men. STRENGTH AND LIMITATIONS: The strength of this study stems from the innovative hypothesis, the young age of participants, and the suggested therapeutic effects of cheap dietary components against ED. Limitations include the relatively small sample and cross-sectional design. CONCLUSION: Low flavonoid-in particular flavone-intake is associated with ED in young adult men.

Similar Mediterranean diet adherence but greater central adiposity is observed among Greek diaspora adolescents living in Istanbul, compared to Athens.

OBJECTIVE: The aim of this case-control study was to compare Mediterranean diet (MD) adherence and anthropometry between Greek diaspora adolescents living in Istanbul and Greek adolescents, inhabitants of Athens. DESIGN: A total of 206 adolescents (103 from each site), aged 10.0-19.0 years old, all of Greek origin, were recruited from schools in Athens and minority schools in Istanbul, for the present case-control study. Participants at each site were age and sex-matched. Anthropometric measurements were performed, and diet adherence was assessed with the KIDMED score. RESULTS: Breakfast skipping, decreased dairy and increased commercially baked good/pastries consumption for breakfast, fast-food intake and consumption of several sweets each day was more prevalent in Istanbul, but, on the other hand, students from Athens reported eating fewer fruit, vegetables and nuts. The adoption of unhealthy eating habits in each site was counterbalanced by a more 'healthy' dietary element, resulting in an overall similar MD adherence between both sites. Additionally, although weight status was indifferent between the two cities, higher rates of abdominal obesity were recorded in Istanbul, when the weight-to-height ratio was used for diagnosis. CONCLUSIONS: Differences in several domains of the KIDMED score were recorded among cities, possibly as results of food availability and prices. However, MD adherence and weight status appeared similar, indicating that the dietary transition and acculturation experienced by the remnants is actually very slow and minimal during the 93 years since population exchange.

Food addiction, orthorexia, and food-related stress among dietetics students.

PURPOSE: Health sciences, and in particular Nutrition and Dietetics students, have been shown to exhibit an increased prevalence of disordered eating. The aim of the present cross-sectional study was to evaluate other specified feeding and eating disorders (OSFEDs), including stress-related eating, food addiction, and orthorexia, in relation to the dietary intake, among nutrition/dietetics students. METHODS: A total of 176 undergraduate students from a Department of Nutrition and Dietetics, in Greece, participated in the study. Dietary intake was recorded, and the prevalence of Eating and Appraisal Due to Emotion and Stress (EADES), food addiction (with the modified Yale Food Addition scale mYFAS), and orthorexia were assessed. Chi-square and t tests were performed between sexes, orthorexic and non-orthorexic students, as well as between food-addicted and non-addicted participants. Multiple linear regression analysis assessed relationships between energy intake, BMI or waist circumference, and the food-related psychometric scales. RESULTS: Among participating students, 4.5% had food addiction and 68.2% demonstrated orthorexia. No differences were observed between men and women, concerning the prevalence of food addiction and orthorexia, the sum of mYFAS symptoms, or individual EADES factors. Orthorexic students exhibited increased BMI, reduced energy, and saturated fat intake. In addition, orthorexic men consumed more vegetables. Multiple linear regression analysis revealed that orthorexic behavior was associated with increased BMI, waist circumference and energy intake. Lower BMI was associated with increasing ability to cope with emotion-and-stress-related eating and increasing appraisal of ability and resources to cope with emotions and stress. Emotion-and-stress-related eating was negatively associated with BMI. Appraisal of ability and resources to cope with emotions and stress was associated with the energy intake. Finally, age was positively correlated with the appraisal of outside stressors/influences, indicating increased ability to cope with outside stressors among older students. CONCLUSIONS: The study shows that despite the suggested interventions, the problem of OSFEDs among nutrition and dietetics students is still valid. Regular screening, counseling, and education is needed to reduce its prevalence. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

Efficacy of tyrosine-kinase-2 and phosphodiesterase-4 inhibitors for scalp psoriasis: a systematic review and meta-analysis.

OBJECTIVES: Psoriasis of the scalp is challenging to manage. The only approved oral tyrosine kinase 2 and phosphodiesterase 4 inhibitors for psoriasis are deucravacitinib and apremilast. The aim of this study was to explore their efficacy for scalp psoriasis utilizing data from randomized controlled trials. METHODS: We searched Medline, Scopus, Web of Science, CENTRAL, and ClinicalTrials.gov up to August 4, 2023. To determine risk of bias, the revised Risk of Bias assessment tool 2.0 was used. Inverse variance random effects meta-analyses were executed. Heterogeneity was assessed utilizing Q and I2 statistics. Pre-determined outcomes included the proportion of participants with cleared scalp skin (Scalp Physician's Global Assessment [ScPGA] of 0/1), mean change in Psoriasis Scalp Severity Index (PSSI), and mean improvement in Dermatology Life Quality Index (DLQI). RESULTS: Ten RCTs fulfilled inclusion criteria. Both apremilast (RR = 2.41, 95% CI = 2.08-2.79, Tau2 = 0, I2 = 0) and deucravacitinib (RR = 3.86, 95% CI = 3.02-4.94, Tau2 = 0, I2 = 0) were more effective in inducing ScPGA of 0/1 at 16 weeks compared to placebo. Furthermore, deucravacitinib was more effective than apremilast (RR = 1.70, 95% CI = 1.44-2.00, Tau2 = 0, I2 = 0). An analysis could not be executed for the rest of the outcomes. CONCLUSIONS: Apremilast and deucravacitinib are effective for scalp psoriasis. Deucravacitinib may be more efficient in clearing the scalp.

Biotics and Children's and Adolescents' Health: A Narrative Review.

Recently, there has been an increasing interest in the association of gut microbiota with health conditions and the potentially beneficial role of several types of biotics in several population groups, including children and adolescents. Children and adolescents comprise a unique population group due their rapid growth rates, high nutritional requirements, the immaturity of their immune system in early life, and their susceptibility to infectious diseases. The aim of the present study is to investigate the role and limitations of the administration of biotics in specific conditions affecting children and adolescents. A narrative review of related articles published on PubMed up to October 2023 was conducted. The administration of biotics has been evaluated in several health conditions among children and adolescents, such as the treatment and prevention of infectious diarrhea, the prevention of diarrhea after the use of antibiotics, the prevention of necrotizing enterocolitis, the treatment of functional gastrointestinal diseases, such as infant colic, functional abdominal pain, and irritable bowel syndrome, the eradication of H. pylori, the treatment of ulcerative colitis and pouchitis, and the prevention of atopic dermatitis, and the findings indicate improved symptoms and various beneficial health outcomes. However, some limitations have been identified regarding probiotics' use. In conclusion, biotics may have a beneficial impact in several health conditions among children and adolescents. There is a need for additional randomized, controlled clinical studies on the effects of the administration of biotics in children and particularly in adolescents and young adults.

Food Insecurity in Greece and across the Globe: A Narrative Literature Review.

Food insecurity comprises a major global public health threat, as its effects are detrimental to the mental, physical, and social aspects of the health and well-being of those experiencing it. We performed a narrative literature review on the magnitude of global food insecurity with a special emphasis on Greece and analyzed the major factors driving food insecurity, taking into consideration also the effect of the COVID-19 pandemic. An electronic search of international literature was conducted in three databases. More than 900 million people worldwide experience severe food insecurity, with future projections showing increasing trends. Within Europe, Eastern and Southern European countries display the highest food insecurity prevalence rates, with Greece reporting a prevalence of moderate or severe food insecurity ranging between 6.6% and 8% for the period 2019-2022. Climate change, war, armed conflicts and economic crises are major underlying drivers of food insecurity. Amidst these drivers, the COVID-19 pandemic had a profound impact on food insecurity levels around the globe, through halting economic growth, disrupting food supply chains and increasing unemployment and poverty. Tackling food insecurity through addressing its key drivers is essential to any progress towards succeeding the Sustainable Development Goal of "Zero Hunger".

Beat the Clock: Assessment of Night Eating Syndrome and Circadian Rhythm in a Sample of Greek Adults.

The night eating syndrome (NES) is characterized by excessive food intake during the evening and night hours, with 25% of the daily intake being consumed post-dinner, paired with ep-isodes of nocturnal food intake, at a frequency of more than twice weekly. The NES has been associated with a misaligned circadian rhythm related to a delay in overall food intake, increased energy and fat consumption. The present cross-sectional study aimed to assess NES in a Greek population and evaluate possible links between NES and chronotype. NES was assessed using the Night Eating Questionnaire (NEQ), and circadian rhythm, sleep and mood were evaluated with the Sleep, Circadian Rhythms, and Mood (SCRAM) questionnaire. A total of 533 adults participated in the study. A relatively high prevalence of NES was revealed, with more than 8.1% (NEQ ≥ 30) of the participants reporting experiencing NES symptoms, depending on the NEQ threshold used. Most participants had the intermediate chronotype. NEQ score was positively associated with the morning chronotype, and SCRAM was negatively related to "Good Sleep". Each point increment in the depression score was associated with 6% higher odds of NES. The early identification of NES gains importance in clinical practice, in a collective effort aiming to reduce NES symptomatology and its detrimental health effects.
