Tirzepatide is a glucagon-like peptide-1 (GLP-1) receptor agonist and glucose-dependent insulinotropic polypeptide (GIP) analog approved for treatment of Type 2 Diabetes Mellitus, obesity and moderate-to-severe obstructive sleep apnea in patients with obesity. The role of the GLP-1 drugs in treating eating disorders is unclear. Night Eating Syndrome (NES) and Sleep-Related Eating Disorder (SRED) are conditions in which sleep parasomnias and eating behaviors overlap. Their treatment remains challenging and includes cognitive behavioral therapy and pharmacotherapy using topiramate, selective serotonin reuptake inhibitors, or anorectic serotonergic medications. We report two cases of NES, one of them with comorbid SRED, treated successfully with tirzepatide.

Insomnia is increasingly prevalent among university students, adversely affecting both academic performance and psychological well being. This study presents a comprehensive behavioral modeling framework linking sleep disruption to academic outcomes using self reported psychometric data from 996 undergraduate students across all four academic years. The dataset captured sleep patterns, lifestyle factors, stress, and academic performance indicators through a structured questionnaire survey. A significant negative correlation was observed between sleep disturbances and GPA. Unsupervised clustering of sleep and lifestyle features revealed distinct behavioral subgroups, while supervised classifiers validated through both 80/20 train–test split and 3-fold cross-validation achieved strong predictive performance (AUC = 0.96, F1 = 0.89). Permutation based feature importance identified sleep-onset difficulty, perceived stress, and caffeine consumption as dominant predictors of academic decline. These findings demonstrate the value of integrating psychometric assessment with machine learning to identify students at academic risk and provide a foundation for data-driven interventions in higher education.
失眠在大学生中越来越普遍，对学习成绩和心理健康都有不利影响。本研究利用996名本科生四个学年的自我报告心理测量数据，提出了一个将睡眠中断与学业成绩联系起来的综合行为建模框架。该数据集通过结构化问卷调查捕获了睡眠模式、生活方式因素、压力和学习成绩指标。睡眠障碍与GPA呈显著负相关。睡眠和生活方式特征的无监督聚类揭示了不同的行为亚组，而经过80/20训练检验分割和3倍交叉验证的监督分类器具有较强的预测性能（AUC = 0.96, F1 = 0.89）。基于排列的特征重要性确定了睡眠开始困难、感知压力和咖啡因摄入是学业下降的主要预测因素。这些发现证明了将心理测量评估与机器学习结合起来识别有学业风险的学生的价值，并为高等教育中数据驱动的干预提供了基础。

Background
Sixth-year medical students (interns) experience intense working conditions and need to prepare for medical specialization examination. All these stress factors negatively affect students’ sleep quality.
Methods
An online survey was conducted in 223 out of 534 interns between April and July 2023 in a university hospital in Türkiye. Sleep quality, fatigue and stress levels were evaluated by Pittsburgh Sleep Quality Index (PSQI), Chalder Fatigue Scale (CFS) and Visual Analogue Scale (VAS), respectively (PSQI >5, CFS ≥29, VAS 6.78 ± 1.82 (range 0–10), with higher values indicating greater momentary perceived stress.).
Results
Out of 223 interns (46.1% women, mean age 24 years), 177 (79.4%) had poor sleep quality. Moderate or high fatigue severity was observed in 94.4% of the students with poor sleep quality, whereas only 52.2% of those with good sleep quality had moderate fatigue risk (p<0.001). Participants with poor sleep quality had lower incomes (p=0.002), higher stress levels (p=0.005) and higher fatigue scores (p=0.001) compared to those with good sleep quality. Additionally, low socioeconomic status (odds ratio [OR], 25.625, 95% confidence interval [CI] 3.313-98.196; p=0.002), increased stress levels (OR, 2.838, CI 1.369-5.882; p=0.005), high stress (OR, 2.053, CI 1.051-4.010; p=0.035), and fatigue severity (OR, 15.308, CI 6.470-36.223; p<0.001) were associated with poor sleep quality.
Conclusion
Most of the interns (79.4%), working under demanding conditions, had poor sleep quality, leading to increased risk of fatigue severity. Low incomes and high stress levels were predictors of poor sleep quality.
六年级医学生（实习生）需要经历高强度的工作条件，需要为医学专业考试做准备。这些压力因素都对学生的睡眠质量产生了负面影响。方法于2023年4月至7月，对台湾省某大学医院534名实习生中的223名进行在线调查。采用匹兹堡睡眠质量指数（PSQI）、查尔德疲劳量表（CFS）和视觉模拟量表（VAS）分别评价睡眠质量、疲劳和应激水平（PSQI >5, CFS≥29,VAS 6.78±1.82（范围0-10），数值越高表示瞬时感知应激越大）。结果223名实习生中，女性占46.1%，平均年龄24岁，其中睡眠质量差的177人占79.4%。94.4%睡眠质量差的学生存在中度或高度疲劳风险，而睡眠质量好的学生只有52.2%存在中度疲劳风险（p < 0.001）。与睡眠质量好的参与者相比，睡眠质量差的参与者收入更低（p=0.002），压力水平更高（p=0.005），疲劳评分更高（p=0.001）。此外，低社会经济地位（优势比[OR]， 25.625, 95%可信区间[CI] 3.313-98.196; p=0.002）、压力水平增加（OR, 2.838, CI 1.369-5.882; p=0.005）、高压力（OR, 2.053, CI 1.051-4.010; p=0.035）和疲劳程度（OR, 15.308, CI 6.47 -36.223; p<0.001）与睡眠质量差相关。结论绝大多数实习生（79.4%）在高要求的工作条件下工作，睡眠质量较差，导致疲劳严重程度的风险增加。低收入和高压力水平是睡眠质量差的预测因素。

This study aimed to investigate the association between the use of pre-workout dietary supplements and average sleep duration among adolescents and young adults. Data from Wave 2 of the Canadian Study of Adolescent Behaviors (N = 912) were analyzed. Multinomial logistic regression analyses were conducted to investigate the cross-sectional association between the use of pre-workout dietary supplements in the past 12 months and average sleep duration in the past 2 weeks. Adolescents and young adults who reported pre-workout dietary supplement use were at greater risk (RRR 2.53, 95% CI 1.27–5.05, p = 0.09) of reporting ≤5 h of average sleep per night relative to 8 h of sleep. Findings underscore that the high caffeine content of pre-workout dietary supplements is associated with shorter sleep durations, which are well below the recommended guidelines for adolescents and young adults. Health and mental health care professionals should educate pre-workout users on the association between use and sleep.
这项研究旨在调查青少年和年轻人运动前膳食补充剂的使用与平均睡眠时间之间的关系。我们分析了加拿大青少年行为研究第二波的数据（N = 912）。采用多项逻辑回归分析来调查过去12个月运动前膳食补充剂的使用与过去2周平均睡眠时间之间的横断面关联。报告锻炼前使用膳食补充剂的青少年和年轻人报告每晚平均睡眠时间≤5小时的风险更大（RRR 2.53, 95% CI 1.27-5.05, p = 0.09）。研究结果强调，运动前膳食补充剂的高咖啡因含量与较短的睡眠时间有关，这远远低于青少年和年轻人的推荐指南。健康和精神卫生保健专业人员应该教育锻炼前的使用者使用和睡眠之间的关系。

Background
Long-term adherence to continuous positive airway pressure (CPAP) therapy in obstructive sleep apnea (OSA) often falls below 30 %. We report the first two-year evaluation of CPAP adherence among Vietnamese patients with moderate to severe OSA.
Methods
In this prospective cohort, 32 treatment-naïve adults (Apnea–hypopnea index -AHI ≥ 15 events/h) were enrolled following in-lab polysomnography. Adherence was defined as ≥ 4 h/night on ≥ 70 % of nights over any 30-day period. CPAP monitoring and usage parameters (apnea-hypopnea index - residual AHI, compliance, adherence, P95 pressure- Mean 95th percentile CPAP pressure, air leakage) were recorded at 1, 3, 6, 9, 12, and 24 months. Predictors of long-term adherence were analyzed using correlation models.
Results
All 32 participants completed follow-up. Adherence rates were 65.6 % at 1 month, 53.1 % at 3 months, 46.9 % at 6, 9, and 12 months, and 50.0 % at 24 months. Mean AHI fell from 56.3 ± 18.2 to 2.9 ± 2.8 events/h after one month (p < 0.001) and remained stable. Higher baseline AHI, obstructive apnea index, and apnea duration, lower mean SpO₂, and good 3-month adherence were all significantly associated with sustained use at two years.
Conclusions
Approximately half of Vietnamese patients with moderate to severe OSA remain adherent to CPAP after two years. Both initial disease severity and early treatment adherence independently predict long-term adherence, underscoring the importance of close monitoring and intervention during the first three months of therapy.

Background/Objectives
A chronotype is an expression of an individual circadian rhythm associated with sleep and physical activity. It categorizes people as morning, intermediate and evening chronotype. The aim of this systematic review was to evaluate the association of chronotype with glucose metabolism at population level..
Methods
The study was conducted in accordance with the international PRISMA Code of Systematic Reviews. Covidence was used for data selection. We included articles that utilized data from unselected populations. Articles were excluded primarily based on the characteristics of the study population, including shift workers, patients with specific disease and children.
Results
Finally, there were a total of ten articles that met the eligibility criteria. Eight studies had a cross-sectional setting, and three had prospective study design. Seven out of ten articles reported a statistically significant association between evening chronotype and glucose metabolism disorders. The number of participants in the studies varied (N = 447 to 360,403). Parameters used to examine glucose metabolism were diabetes, prediabetes, fasting glucose, fasting insulin, Hemoglobin A1c (HbA1c), Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), and two hours oral glucose tolerance test.
Conclusions
Based on the current literature, the evening chronotype appears to be positively associated with adverse changes in glucose metabolism, such as increased fasting glucose and insulin resistance, as well as type 2 diabetes. In the future, it might be necessary to further study the association between chronotype and glucose metabolism. Longitudinal analyses are needed in large research populations in order to verify the existence of the association.

Sleep disturbances negatively impact individuals’ physical, psychological, and social health and individual performance. This study aimed to examine the prevalence of sleep disturbances in Morocco as its primary objective and the related risk factors as a secondary objective, using a sample of 1010 participants from seven Moroccan regions selected for their population density and socio-cultural diversity.
Participants and methods
Participants were interviewed over the telephone by an accredited expert call center. Information on sleep disturbances and habits was collected using sleep disturbance questionnaires, which distinguish two main sleep disturbances: insomnia symptoms and excessive daytime sleepiness. Logistic regression models were used for risk factors.
Results
We collected data from 1,010 participants, yielding a response rate of 61.77 %. The mean age was 44.90 (±16.09) years (range: 18-96), with a female preponderance (78 %). Insomnia symptoms prevalence rate reached 30.2 % (95 % CI: 27.4–33.1), and the excessive daytime sleepiness prevalence rate was 17.9 % (95 % CI: 15.7–20.4). Among sociodemographic parameters (age, sex, educational level, and comorbidities), the female sex and educational level were associated with a higher prevalence of sleep disturbances.
Conclusions
Insomnia symptoms (30.2 %) were the most prevalent sleep disturbances. Its prevalence was higher among females (33.4 %; 95 % CI: 30.2–36.7) than males (18.9 %; 95 % CI: 14.3–24.6). Similarly, for excessive daytime sleepiness, the prevalence was higher among females (19.8 %; 95 % CI: 17.2–22.7) than males (11.3 %; 95 % CI: 7.7–16.1).

Objectives
To examine the associations of screen time (ST) and physical activity (PA) with sleep health, considering mental health.
Methods
This cross-sectional study began in April 2020 during the COVID-19 health crisis. Changes in ST over the past 7 days were rated on a 3-point Likert scale (1 = decrease or no increase; 2 = moderate increase; 3 = uncontrolled increase). PA over the past 7 days was also rated on a 3-point Likert scale (1 = no; 2 = yes, but not every day; 3 = yes, every day). Anxiety and depressive symptoms were assessed using the Generalized Anxiety Disorder-7 scale and the Patient Health Questionnaire-8, respectively.
Results
In total, 2036 participants were enrolled (mean age: 29.4 years; 79 % female). Longer ST was associated with worse sleep health, with an odds ratio (OR) of 1.70 (95 % confidence interval [CI]: 1.42–2.05) for a moderate increase and 3.40 (95 % CI: 2.69–4.30) for an uncontrolled increase, compared with no increase. Lower PA was also associated with worse sleep health, with an OR of 1.25 (95 % CI: 1.05–1.50) for weekly practice and 1.72 (95 % CI: 1.35–2.19) for no practice, relative to daily practice. The effects of ST and PA were cumulative. Additional adjustments for anxiety and depressive symptoms did not explain or alter the associations.
Conclusions
ST and PA are both critical for sleep health. Interventions aimed at improving sleep should systematically consider their roles. Longitudinal studies conducted in a more stable health context are needed to confirm these findings.

Background
Biphasic sleep (segmented sleep) has been documented in preindustrial societies. The Biphasic Sleep Scale (BiSS) was recently developed to measure this pattern. This study aimed to translate and validate the BiSS into Arabic.
Methods
The BiSS was translated following international cross-cultural adaptation guidelines. A cross-sectional survey of 511 Arabic-speaking young adults (mean age = 22.1 years; 73.8 % female) used the Arabic BiSS and Glasgow Sleep Effort Scale. Analysis included descriptive statistics, confirmatory factor analysis (CFA), reliability analysis (Cronbach's α and McDonald's ω), correlations, and regression models examining age, sex, and marital status effects.
Results
CFA confirmed the original three-factor structure—likelihood of first sleep, consequences of first sleep, and sleep disturbance—with acceptable fit (RMSEA = 0.05, 90 % CI [0.02, 0.06]; SRMR = 0.04; CFI > 0.9; TLI > 0.9). Internal consistency was robust for the total scale, α = 0.9 and ω = 0.9. Internal consistency was also acceptable for subscales: likelihood of first sleep (α/ω = 0.8), consequences of first sleep (α/ω = 0.8), and borderline for sleep disturbance (α/ω = 0.6). Age (β = 0.1, p = 0.03) and marital status (single vs. married; β = -0.4, p = 0.02 for likelihood; β = -0.4, p = 0.01 for consequences significantly predicted biphasic sleep tendencies, while sex showed no significant effect.
Conclusion
The Arabic BiSS demonstrates sound psychometric properties for assessing biphasic sleep. Future research should examine applicability in diverse populations, including older adults and married individuals, and further validate the sleep disturbance dimension.
