- The relation between sleep quality, psychopathology, gender, and severity of aggressive behavior among psychiatric patientsPublication . Alves-Ferreira, Domingos; Costa, Eleonora; Santos, JorgeObjective: The objectives of this study were to ascertaining whether sleeping problems affect aggression levels in adult offenders undergoing inpatient psychiatric treatment and exploring the phenomenon in terms of differences in gender, crime severity, and psychopathology. Methods: We used a sample of 70 adult male and female offenders, inpatients of a forensic psychiatry hospital, to whom we applied the Pittsburgh Sleep Quality Index (PSQI), which evaluates the subjective sleep quality, latency, duration, habitual subjective sleep efficiency, sleep disturbances, use of sleeping medication, and impairing daytime sleepiness in the preceding 30 days, and the Aggression Questionnaire (AQ), which measures physical and verbal aggressiveness, hostility, and anger. Results: A positive correlation between sleep quality and level of aggression was found (r =.254, p <.05; r2=.065). There were no significant correlation between sleep quality and crime severity (X2 = 1,984, p =.371). When controlled by gender, women showed significantly worse sleep quality than men (Z = 2,243, p =.025) but no significant difference in aggression level (Z = -1,806, p =.071). There were no significant difference in either sleep quality or aggression level among individuals diagnosed with different kinds of psychopathology (X2 = 4,366, p =.359) (X2 = 2,248, p =.690). Conclusion: The results show a relationship between sleep quality and aggression level, but the relationship is correlated to neither crime severity nor psychopathology.
- Weight loss in patients with severe obesity after bariatric surgery - the potential role of the chrono-nutrition, chronotype and the circadian misalignment: a study protocol of the ChronoWise prospective cohortPublication . Rodrigues, Joana; Magalhães, Vânia; Santos, Maria Paula; Reis, Cátia; Pichel, Fernando; Soares, Paulo; Santos, Jorge; Vilela, SofiaBackground Despite the potential effectiveness of bariatric surgery in promoting weight loss, a considerable proportion of patients still face the challenge of achieving optimal post-surgery outcomes. The timing of eating, in addition to the content of what is eaten, as well as chronotype and social jetlag (a marker of circadian misalignment), have been implicated in weight regulation. However, the current understanding of these chrono-related behaviours in individuals undergoing bariatric surgery is still scarce. Thus, this study aims to evaluate the role of chrono-nutrition, chronotype, and circadian misalignment in the weight-loss trajectory among individuals living with severe obesity who underwent bariatric surgery. Methods The ChronoWise project is a prospective single-centre cohort study designed to follow patients experiencing bariatric surgery at the Santo António Local Health Unit (ULSSA), Porto, Portugal. Participants will be recruited and evaluated at pre-surgery and followed-up over 3 and 6 months after surgery. The baseline evaluation will be conducted face-to-face during the hospital stay and by telephone or video call on the subsequent evaluations, following standard procedures. Data collection includes sociodemographics, food intake, chrono-nutrition behaviours, sleep time behaviour, sleep quality, screen time, physical activity and exercise behaviours, anthropometric measurements, and biochemical parameters. The ‘Munich Chronotype Questionnaire’ will be used to assess chronotype and social jet lag. Chrono-nutrition dimensions will be measured by the ‘Chrononutrition Profile—Questionnaire’ in all evaluations. Weight and height will be self-reported and retrieved from medical registries. trajectories of weight-loss will be obtained. Discussion This study will add important evidence on the role of chrono-nutrition, chronotype and social jetlag profile in weight-loss outcomes after bariatric surgery. Identifying novel approaches to change the paradigm of post-surgical weight management towards a tailored treatment aligned with circadian rhythm may be useful to strengthen the existing treatments and improve patients’ response to bariatric surgery.
