This narrative review presents the findings from intervention studies on the effects of sleep deprivation on eating habits, metabolic rate, and the hormones regulating metabolism, and discusses their relevance to weight loss efforts. Disturbed sleeping patterns lead to increased energy intake, partly from excessive snacking, mainly on foods high in fat and carbohydrates. The studies focused mainly on the effects of sleep duration, but also of sleep quality, on dietary intake during weight loss trials, and on weight loss maintenance. It is important to explore sleep routines that could enhance the efforts of obese and overweight people to lose weight, maintain their weight loss, and improve their overall health.

(1) Background: The second-generation antipsychotics (SGAPs) induce metabolic and inflammatory side effects, but documentation of their effects on the liver and kidneys is scarce. Aim: To study the three-year fluctuation of selected markers of renal and hepatic function in forensic psychiatric patients receiving SGAPs for more than five years. (2) Methods: Thirty-five forensic psychiatric patients (N = 35) were classified into two groups according to the type of SGAPs used for their treatment and the relevant risk of weight gain and metabolic complications. The three-year medication history, anthropometric data and biochemical data relevant to renal and hepatic function were retrieved from the individual medical files, specifically: serum levels of urea, uric acid, creatinine, alkaline phosphatase and amylase; the liver function enzymes, serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT) and gamma-glutamyl transpeptidase(γ-GT), and also the inflammatory index C-reactive protein (CRP). (3) Results: The patients receiving the SGAPs with a low risk for weight gain showed no significant fluctuation in the biochemical markers over the three-year period. The patients receiving the SGAPs with a high risk for weight gain showed significant differences between at least two measurements of uric acid (p = 0.015), SGOT (p = 0.018) and SGPT (p = 0.051). They showed significantly higher levels of creatinine in the third year compared to the second year (p = 0.029), and SGOT in the second year compared to the first (p = 0.038), and lower levels of SGPT in the third year compared to the second (p = 0.024). (4) Conclusion:In addition to consideration of possible metabolic and inflammatory complications, the choice of an antipsychotic drug for long-term treatment should also take into account the risk of hepatotoxicity and kidney damage.

Background: Schoolchildren are likely to consume meals and snacks at school, with a possibility of allergic food reactions and anaphylaxis in the school environment. The school personnel should be informed of the presence of schoolchildren with food allergy (FA) and need to be trained in the management of allergic reactions, as to prepare them to intervene appropriately when necessary. Limited knowledge of FA and its management is documented globally among school staff and there is no uniform protocol in schools. Methods: In this observational cross-sectional study, teachers at state schools throughout Greece completed an online anonymous questionnaire on their awareness of FA reactions and the plans for the management of medical emergencies in their schools of employment. Results: Among the 289 teachers who responded the online invitation, 203 (70.24%) were female and 157 (54%) were aged under 40 years. Females expressed a higher level of concern about the presence of school personnel trained to manage FA symptoms (p = 0.001), written instructions, and the availability of adrenaline (epinephrine) at school (p < 0.001). A younger age was associated with a higher level of both interest and knowledge on FA management in schools. School directors were more certain about the availability of a special record of children with FA at school (p = 0.01), the availability of adrenaline (p = 0.006), and written guidelines on the management of serious health incidents at school (p = 0.04). Written guidelines instructing children to avoid sharing cutlery, glasses, home-prepared meals, and snacks bought from the school canteen were more common in schools in urban areas (p = 0.015). Only 20% of respondents could confirm with certainty that adrenaline autoinjectors (AAIs) were available at their schools, for the purpose of administering to children in the case of a severe FA reaction. Approximately 3/4 of the participating teachers stated that completion of this questionnaire raised their awareness of the risk of FA reactions in children at school. Conclusions: This study, the first in Greece to explore the knowledge of teachers about FA in schoolchildren, revealed the following absences in many schools: a process for identifying children with FA, a written emergency treatment plan, and immediate access to emergency AAI. School FA guidelines are necessary in Greece, and training, which includes the use of AAIs, is required to prepare teachers to manage FA reactions in children at school.

Many studies have shown that COVID-19 caused many problems in mental health. This paper presents the results of the Cyprus sample, part of the global initiative named “The Collaborative Outcomes Study on Health and Functioning during Infection Times” (COH-FIT). Methods: The study took place from April 2019 to January 2022, using the Greek version of the online standard COH-FIT questionnaire on 917 Cypriot adults. Weighted t-tests were applied to test the differences between pre-pandemic and intra-pandemic scores using the anesrake package. Results: Participant responses indicated a significant negative impact of the pandemic on measures of mental health (−7.55; 95% CI: −9.01 to −6.07), with worsening in the scores for anxiety (12.05; 95% CI: 9.33 to 14.77), well-being (−11.06; 95% CI: −12.69 to −9.45) and depression (4.60; 95% CI: 2.06 to 7.14). Similar negative effects were observed for feelings of anger (12.92; 95% CI: 10.54 to 15.29), helplessness (9.66; 95% CI: 7.25 to 12.07), fear (22.25; 95% CI: 19.25 to 25.26), and loneliness (12.52; 95% CI: 9.94 to15.11). Increased use of social media (0.89; 95% CI: 0.71 to 1.09), internet (0.86; 95% CI: 0.67 to 1.04), and substance consumption (0.06; 95% CI: 0.00 to 0.11) were reported, along with a significant decrease in physical health (−3.45; 95% CI: −4.59 to −2.32), self-care (−7.10; 95% CI: −9.00 to −5.20), and social function (−11.27; 95% CI: −13.19 to −9.35), including support (−0.72; 95% CI: −1.09 to −0.34) and family function (−7.97; 95% CI: −9.90 to −6.05). Conclusions: The COVID-19 pandemic significantly affected the daily life and emotional well-being of Cypriots. Identifying factors that influence vulnerability and resilience is essential to prioritize mental health support and address the long-term effects of the pandemic.
