The Mediterranean diet has consistently shown a beneficial influence on health and longevity. The aim of this cross-sectional study was to identify all the various factors—such as socio-demographics, lifestyles, and behavioral traits—associated with the risk of a poor adherence to the Mediterranean diet in a sample of Italian primary school children. The study sample included 267 children in their first year of primary school. Their mothers were asked to answer an anonymous, self-administered questionnaire that investigated their children’s adherence to the Mediterranean diet (using the KidMed score) and variables related to their lifestyles, behavioral traits, and socio-economic factors. A multivariate logistic regression was performed to test the association between adherence to the Mediterranean diet and the other variables investigated. Most of the children involved in this study (73.9%) were classifiable as having a poor-to-moderate adherence to the Mediterranean diet. Higher odds of a poor adherence to the Mediterranean diet were associated with videogame playing for more than 1 h a day and lower levels of mothers’ health consciousness. On the other hand, the odds were lower in association with more time spent practicing sport, higher levels of prosocial behavior, and with mothers having a high school education as opposed to fewer years of schooling.Conclusions: These results point to the need to consider the role of mothers’ health consciousness and formal education in influencing their children’s diets. Health promotion interventions should focus on the importance of a healthy overall lifestyle, which includes not only appropriate nutrition but also time spent on physical activity and leisure activities (such as playing videogames).What is Known:• Most of the children were classified as having a poor or moderate adherence to the Mediterranean diet. This result reflects a trend common to numerous countries of the Mediterranean area in recent years.• A mother’s level of formal education influences her child’s diet.What is New:• Higher levels of prosocial traits coincided with lower odds of a poor adherence to the Mediterranean diet.

Very low-calorie ketogenic diet (VLCKD) is a low-carbohydrate, low-calorie regimen that leads to rapid weight loss and may reduce inflammation. This study assessed the impact of VLCKD on anthropometric measurements, inflammatory biomarkers, metabolic health, and cardiovascular risk in psoriatic arthritis (PsA) patients moderately overweight or in class I obesity. A proof-of-concept single-arm monocentric study involved PsA patients undergoing a 9-week VLCKD treatment. Patients with Body Mass Index (BMI) ≥27 and <35, in stable (≥6 months) remission or low disease activity, as defined by Disease Activity in PSoriatic Arthritis (DAPSA) score, were included and underwent nutritional evaluations every 3 weeks. The study analyzed changes after the VLCKD intervention and the association between changes of anthropometric parameters and clinical and laboratory variables. Twenty patients were enrolled since April 2022 and completed the study in May 2023. Median baseline BMI was 30.9 (interquartile range 29.1-33) kg/m². All participants exhibited low baseline disease activity, which correlated with BMI (Spearman's correlation coefficient (rs)=0.59,p=0.007). Following VLCKD, significant improvements were observed in all anthropometric measures (BMI -3.5[-4;-2.6]), PsA activity (DAPSA -6.1[-16.8;3.7]), cardiovascular parameters (SCORE2 index -0.2[-0.7;0.1]), insulin resistance (Homeostatic Model Assessment-Insuline Resistance -2.1[-1.1;-3.0]), and lipid profile. Most inflammatory biomarkers remained within normal limits. BMI reduction correlated with changes in DAPSA scores (rs=0.52,p=0.020). Patients with higher baseline weight or clinical activity experienced more pronounced improvements. VLCKD significantly improved PsA activity and metabolic health. Patients with a higher BMI and less controlled disease are particularly motivated and could benefit more from VLCKD compared to those with lower BMI or better disease control.

Background Stress and negative emotions may impact on appetite, inducing some individuals to eat less and others to eat more. This behavior has been implicated in the onset of bodyweight problems and eating disorders in childhood. The aim of our study is to evaluate factors potentially associated with emotional eating in children. Methods The present cross-sectional study derives from a survey conducted in 2021 on 8–9 years old children attending 11 primary schools. A questionnaire was administered that contained multiple-choice items relating to the children and their mothers, and touching on all the factors thought to be associated with emotional eating as behavioral traits or adherence to Mediterranean diet. A multivariable logistic regression was performed to test the association. Results Emotional undereating was positively associated with emotional symptoms (OR 1.72; 95% CI 1.11–2.67); emotional overeating was positively associated with both emotional symptoms (OR 2.01; 95% CI 1.29–3.13) and hyperactivity (OR 2.80; 95% CI 1.59–4.92), and inversely associated with peer problems (OR 0.50; 95% CI 0.25–0.99). Emotional undereating was also positively associated with the number of siblings (OR 1.50; 95% CI 1.03–2.18), and inversely associated with a good adherence to the Mediterranean diet (OR 0.25; 95% CI 0.08–0.84). Conclusions The study found children’s emotional eating associated with both dietary patterns and behavioral traits (in particular emotional symptoms, hyperactivity and peer problems). It could be useful to improve parents’ awareness so that they can anticipate and pay more attention to this issue. Adherence to the Mediterranean diet should also be reinforced, by means of health promotion interventions at school, for example.

Wernicke's encephalopathy (WE) is an acute disorder due to thiamine deficiency, characterized by ophthalmoplegia, ataxia, and mental confusion, similar to that classically observed in alcoholism. Some cases of WE were reported to coincide with other conditions such as hyperemesis gravidarum, bariatric surgery, and total parenteral nutrition. In this study the objective was to retrospectively evaluate the prevalence of WE among intravenously fed patients in our hospital during the previous 2 y. Among all cases of WE diagnosed by cranial magnetic resonance scan during a 2-y period in the Azienda Ospedaliera of Padua, we identified patients who exhibited WE during parenteral feeding. Albumin plasma levels, measured at the onset of WE symptoms, were used to estimate nutritional status. We found seven cases of WE that coincided with intravenous feeding. WE occurred, on average, 13 d after the start of glucose infusion. The five subjects with albumin plasma levels lower than 35 g/L at the onset of WE received glucose infusion for fewer days. In six cases the clinical signs disappeared the day after thiamine infusion. In one case mental function did not normalize and the patient developed Korsakoff's syndrome despite prolonged thiamine treatment. During a 2-y period we observed a high prevalence of WE in intravenously fed patients due to lack of thiamine supplementation. A prophylactic treatment must be performed in at-risk patients and multivitamin infusion containing thiamine must be administered daily during the course of intravenous feeding.

Background: Increased screen time in children is significantly associated with lower adherence to the Mediterranean diet (MD). The purpose of this study was to explore the association between different types of media use and the adherence to the MD in children. Methods: The study sample included 332 children aged 10–11 years attending the fifth year of primary school in Veneto, north-east Italy. The children’s mothers were surveyed on their children’s adherence to the MD, using the KidMed questionnaire, and on the time of media use, using the Media Activity Form-Parent (MAF-P). A multivariable backward stepwise linear regression was applied, adjusting the association for other potential confounding factors. Results: Children’s primary digital activities were watching TV or streaming platforms (5.0 h/week) and video content (2.5 h/week), followed by digital games (2.3 h/week). Lower adherence to the Mediterranean diet was associated with digital games (regression coefficient −0.65, SE 0.29, p = 0.026) and time spent watching TV or streaming platforms (regression coefficient −0.60, SE 0.29, p = 0.04). Conclusion: Interventions to promote healthier diets justify an approach that includes media education. Providing parents with recommendations on children’s use of digital media devices can empower them to improve their children’s well-being.

We describe a case of irreversible subacute sclerotic combined degeneration of the spinal cord in a Western vegan subject. A 57-y-old man, member of a vegan cult for 13 y, developed weakness, paraplegia, hyper-reflexia, distal symmetric muscular hypotrophy, impairment of superficial sensation in the hands and feet, loss of deep sensation in the lower limbs, and neurogenic bladder and bowel. Magnetic resonance imaging of the cervical and dorsal spine disclosed abnormally increased signal intensity on T 2-weighted sections in the posterior and lateral columns. Subacute sclerotic combined degeneration of the spinal cord was diagnosed and treatment with cobalamin was started. Despite rehabilitative treatment, the patient developed spastic hypertonia with mild improvement of paresthesias. Six months later, vitamin B12 plasma levels and hematological analysis were normal. One year later, spastic paraplegia was still present and the patient was unable to walk despite improvement on magnetic resonance imaging. Irreversible subacute sclerotic combined degeneration of the spinal cord is a rare but possible effect of a strict vegetarian diet.

Background: Thiamine deficiency in humans affects the cardiovascular, muscular, nervous, and gastrointestinal systems. Wernicke's encephalopathy is described in alcoholism, in hyperemesis gravidarum, and in prolonged IV feeding without vitamin supplementation. Methods: We report a case of a 66-year-old man undergoing surgery for acute necrotic-hemorrhagic pancreatitis, who presented a Wernicke's syndrome during parenteral nutrition (PN). After surgery, he was treated with infusion of industrial 3-compartment bags, without vitamin supplementation. On the seventh postoperative day, nausea and vomiting began, and 5 days later the patient showed diplopia, ataxia, general muscular stiffness, reduction of osteotendinous reflexes, confusional state, and thrombocytopenia. The magnetic resonance scan evidenced pathologic changes in the medial thalamus, in the third and fourth ventricular floor, in the cerebellar vermis, and in the periaqueductal gray substance. Results: All neurologic signs and platelet blood count gradually normalized after IV supplementation of thiamine, 100 mg daily. The magnetic resonance scan repeated 40 days after the first one was normal. Conclusions: Our report points out the risk of incorrect procedures in management of industrial 3-compartment bags. Moreover, we suggest that thrombocytopenia may be related to thiamine deficiency. We report a case of an inpatient undergoing surgery for acute necrotic-hemorrhagic pancreatitis, who presented a Wernicke’s syndrome and thrombocytopenia during parenteral nutrition with industrial 3-compartment bags. All neurologic signs and platelet blood count gradually normalized after IV supplementation of thiamine.
