Article Abstract
Background/objectives: Obesity is a major contributor to cardiovascular disease, yet traditional risk assessment methods may overlook behavioral and circadian influences that modulate metabolic health. Chronotype, physical activity, sleep quality, eating speed, and breakfast habits have been increasingly associated with cardiometabolic outcomes. This study aims to evaluate the associations between these behavioral factors and both anthropometric and biochemical markers of cardiovascular risk among obese candidates for bariatric surgery.
Methods: A cross-sectional study was conducted in a sample of 286 obese adults (78.3% females, mean 44.3 years, SD = 10.8, mean BMI = 42.5 kg/m, SD = 6.2) followed at a central Portuguese hospital. Chronotype (reduced Morningness-Eveningness Questionnaire), sleep quality (Pittsburgh Sleep Quality Index), physical activity (Godin-Shephard Questionnaire), eating speed, and breakfast skipping were assessed. Cardiovascular risk markers included waist-to-hip ratio (WHR), waist-to-height ratio, A Body Shape Index (ABSI), Body Roundness Index, atherogenic index of plasma (AIP), triglyceride-glucose index (TyG), and homeostatic model assessment for insulin resistance (HOMA-IR).
Results: Men exhibited significantly higher WHR, ABSI, HOMA-IR, TyG, and AIP. Eveningness was associated with higher insulin (r = -0.168, = 0.006) and HOMA-IR (r = -0.156, = 0.011). Poor sleep quality was associated with higher body fat mass (r = 0.151, = 0.013), total cholesterol (r = 0.169, = 0.005) and LDL cholesterol (r = 0.132, = 0.030). Faster eating speed was associated with a higher waist circumference (r = 0.123, = 0.038) and skeletal muscle mass (r = 0.160, = 0.009).
Conclusions: Male sex, evening chronotype, and poor sleep quality were associated with more adverse cardiometabolic profiles in individuals with severe obesity. These findings support the integration of behavioral and circadian factors into cardiovascular risk assessment strategies.

Background: Children with cerebral palsy (CP) may experience epilepsy and challenges with movement, posture, cognition, and musculoskeletal development, which can impact their quality of life (QOL). In this study, we investigated the relationship between demographic and clinical variables as well as QOL in children with spastic CP.
Methods: Children aged 6 to 12 years with CP who were followed-up at our tertiary center were included in this cross-sectional study, regardless of the cause.

Background: Intractable paroxysmal sneezing is a rare and diagnostically challenging condition in children, often mimicking organic diseases. While it is often addressed as psychogenic in the literature, our case presented findings suggestive of a tic disorder, highlighting the need for a broader diagnostic perspective.
Case Presentation: An 11-year-old girl was referred to the child and adolescent psychiatry clinic with a one-year history of persistent and fluctuating sneezing episodes.

Gestational trophoblastic tumors (GTTs) encompass a spectrum of neoplastic conditions, including invasive mole, choriocarcinoma, placental site trophoblastic tumor, and epithelioid trophoblastic tumor. Invasive mole, which frequently develops following a complete hydatidiform mole, represents the most common form. A cancer diagnosis constitutes a profoundly destabilizing experience, often resulting in considerable psychological distress.

Sleep deprivation (SD) is a major contributor to cognitive impairment, often accompanied by central neuroinflammation and gut microbiota dysbiosis. The tryptophan (TRP) pathway, activated via indoleamine 2,3-dioxygenase (IDO), serves as a critical link between immune activation and neuronal damage. Umbelliferone (UMB), a naturally occurring coumarin compound, possesses anti-inflammatory, antioxidant, and microbiota-modulating properties.

Importance: Sleep disturbances are common during and after the menopause transition, with potential effects on morbidity and quality of life; however, they may be underdiagnosed and undertreated.
Objective: We carried out a systematic literature review to investigate the prevalence and impact of sleep disturbances associated with menopause on women's health-related quality of life across the stages of menopause.
Evidence Review: Searches were conducted in PubMed and Excerpta Medica Database to identify articles published between 2013 and 2023 containing evidence for the impact of sleep quality on health-related quality of life and the epidemiology of sleep disturbances in women in menopause.
