Past Bullying Experiences and Depression in College Students: A Moderated-Moderation Model of Parental Monitoring and Family Support

This study examined the association between past bullying victimization and college students’ depressive symptoms, which included mediation (self-esteem) and moderated-moderation (parental monitoring and family support) analysis. This study sample ( n = 362) was collected from South Central and Midwest colleges in the United States. Previous K–12 bullying victimization had a positive association with later life depression among college students which was partially explained by lowered self-esteem. Only a moderate or low level of parental monitoring in the context of high family support buffered the negative impact of past bullying victimization on college students’ depression. However, with low family support, parental monitoring rather increased depression. The transitional period to college life may require restructuring family relationships, and parents excessively monitoring their emerging adult child may not be ideal for mental health among college students who experienced bullying victimization.

Safety evaluation for mixed traffic flow of CAVs with different automation and connection levels

With the development of connected communication and automated driving technologies, connected automated vehicles (CAVs) are expected to gradually replace human-driven vehicles (HDVs), owing to their significant safety advantages. However, widespread adoption of CAVs will still require a considerable amount of time due to constraints such as technological development, legal regulations, and social acceptance. During the transitional period of CAVs’ proliferation, road traffic will comprise vehicles with different levels of connection and automation. These vehicles will differ in technology regarding communication, perception, decision-making, and other aspects, potentially posing severe challenges to mixed traffic flow safety. To address this issue, this paper proposes a mixed traffic flow model from both automation and connection perspectives to consider time delay and communication degradation. Four safety evaluation metrics are employed, and three-speed scenarios are set to investigate the influence of connection levels, automation levels, and their combined effects on mixed traffic flow safety. The result shows that (1) low automation enhances traffic safety in a non-connected environment, whereas medium and high automation decreases traffic safety. Conversely, in a connected environment, the role of automation levels exhibits the opposite pattern. (2) non-connected vehicles enhance traffic safety in a low-automated environment, while connected vehicles diminish it. However, connection level effects are reversed in medium and highly automated environments. (3) In connected and automated environments, traffic safety is increased by non-connected and low-automated vehicles, connected and medium automated vehicles, and connected and highly automated vehicles. However, other vehicle configurations decrease traffic safety. (4) Across various scenarios, the integration of connection and high automation proves beneficial for reducing traffic collision risks and improving traffic safety. In summary, this study provides theoretical support for managing and controlling mixed traffic flow with different automation and connection levels in the future.

Tidal Spin-up of Subdwarf B Stars

Hot subdwarf B (sdB) stars are stripped helium-burning stars that are often found in close binaries, where they experience strong tidal interactions. The dissipation of tidally excited gravity waves alters their rotational evolution throughout the sdB lifetime. While many sdB binaries have well-measured rotational and orbital frequencies, there have been few theoretical efforts to accurately calculate the tidal torque produced by gravity waves. In this work, we directly calculate the tidal excitation of internal gravity waves in realistic sdB stellar models and integrate the coupled spin–orbit evolution of sdB binaries. We find that for canonical sdB (M sdB = 0.47 M ⊙) binaries, the transitional orbital period below which they could reach tidal synchronization in the sdB lifetime is ∼0.2 day, with weak dependence on the companion masses. For low-mass sdBs (M sdB = 0.37 M ⊙) formed from more massive progenitor stars, the transitional orbital period becomes ∼0.15 day. These values are very similar to the tidal synchronization boundary (∼0.2 day) evident from observations. We discuss the dependence of tidal torques on stellar radii, and we make predictions for the rapidly rotating white dwarfs formed from synchronized sdB binaries.

Bridging gaps at key intersections: Strategies to improve early intervention and treatment access for eating disorders

ABSTRACTMental health is at the forefront of discussions in healthcare, education, and social settings, yet eating disorders remain poorly understood and inadequately treated. This paper presents evidence on risk factors for insufficient recognition and intervention for eating disorders across clinical and community healthcare settings and proposes actionable strategies to improve awareness and early intervention for eating disorders. Specifically, gaps in eating disorder awareness and treatment access are exacerbated at two key intersections within health and social systems. First, eating disorders manifest themselves at the intersection of mental and physical categories of health, which places them at risk of being misunderstood, poorly diagnosed, and insufficiently intervened upon. Second, the peak onset of eating disorders falls at the intersection of adolescence and young adulthood, which is a period of rapid developmental, social change, and transitions in care. This analysis highlights how systemic issues within existing social and health systems underlie these intersections and contribute to the continued stigmatization and inadequate treatment access for eating disorders. Given their increased incidence and severity, there is an urgent need to address both the individual and societal burden of these disorders. Healthcare systems must prioritize coordination between physical and mental health practices and improve transitions in care from pediatric and adult healthcare services. Identifying gaps at intersections provides the opportunity to make concrete progress toward improving awareness and treatment.

Turbulent Energy and Carbon Fluxes in an Andean Montane Forest—Energy Balance and Heat Storage

High mountain rainforests are vital in the global energy and carbon cycle. Understanding the exchange of energy and carbon plays an important role in reflecting responses to climate change. In this study, an eddy covariance (EC) measurement system installed in the high Andean Mountains of southern Ecuador was used. As EC measurements are affected by heterogeneous topography and the vegetation height, the main objective was to estimate the effect of the sloped terrain and the forest on the turbulent energy and carbon fluxes considering the energy balance closure (EBC) and the heat storage. The results showed that the performance of the EBC was generally good and estimated it to be 79.5%. This could be improved when the heat storage effect was considered. Based on the variability of the residuals in the diel, modifications in the imbalances were highlighted. Particularly, during daytime, the residuals were largest (56.9 W/m2 on average), with a clear overestimation. At nighttime, mean imbalances were rather weak (6.5 W/m2) and mostly positive while strongest underestimations developed in the transition period to morning hours (down to −100 W/m2). With respect to the Monin–Obukhov stability parameter ((z − d)/L) and the friction velocity (u*), it was revealed that the largest overestimations evolved in weak unstable and very stable conditions associated with large u* values. In contrast, underestimation was related to very unstable conditions. The estimated carbon fluxes were independently modelled with a non-linear regression using a light-response relationship and reached a good performance value (R2 = 0.51). All fluxes were additionally examined in the annual course to estimate whether both the energy and carbon fluxes resembled the microclimatological conditions of the study site. This unique study demonstrated that EC measurements provide valuable insights into land-surface–atmosphere interactions and contribute to our understanding of energy and carbon exchanges. Moreover, the flux data provide an important basis to validate coupled atmosphere ecosystem models.

Its Role In Self Regulated Learning Case Study On Junior High School Students Of It Madani Islamic School

Adolescence is a critical period for student education, where students are in the transition period of childhood to adulthood that undergoes changes in their biological, cognitive and socio-emotional conditions. Based on the stage of development, junior high school students should be able to have responsibility in learning, students are able to manage themselves in their way of learning. The focus of this study aims to examine the role of personality type (based on the STIFIn method) and school climate on the self-regulated learning of SMP IT Madani Islamic School students. Sampling in this study used a total sampling involving 300 students. Data collection uses personality type data (based on the STFIn method), school climate scale and self-regulated learning scale. The data analysis technique used in this study is multiple regression analysis. The results showed that STIFIn personality type and school climate played a significant role in self-regulated learning with a value of F = 44,707 and a value of p<.05. Personality type and school climate made an effective contribution of 26.2% to self-regulated learning.

Modelling pressure dynamics in a gas pipeline with an in-line sampling

Gas pipelines, whether main, field, or urban, often operate in non-stationary modes. Changes in the operating modes of pumping stations, equipment start-up and shutdown, an in-line sampling or pumping and various factors are causes of instability of pressure, velocity, gas flow rate. Main pipelines are complex engineering systems with the pipeline itself being the main element. Fail-safety is the major factor in the operation of this system. Ensuring operational safety requires studying the movement regimes of the transported medium, particularly study of the dynamics of pressure duringstart-up or shutdown and at specific extraction points. This article aims to build a mathematical model and study the pressure dynamics in a gas pipeline with a sampling point. The theory of non-stationary motion liquid in round pipes has been strongly developed in the works of I. A. Charnyj. These works consider a large complex of engineering tasks taking into account viscous properties of the transported medium and pipe resistance in the hydraulic approximation. In the article on the basis of I. A. Charnyj's researches on the motion of real liquid in circular pipes the equation in partial derivatives of hyperbolic type is compiled. The equation describes the unsteady pressure of a horizontal section of gas pipeline with an extraction point. Using the Dirac delta function allows the formulation of the problem in the form of a single equation. Pressures are set at the ends of a given section, and the initial velocity is related to the Dirac delta function. By applying the finite Fourier sine transform, the partial differential equation is transformed into an ordinary differential equation and solved. Solution of equation is vision of a solution to the initial task. Inverse transform formulas based on Fourier theory allowed us to proceed to the solution of this task. Explicit dependences for the dynamics of unsteady pressure are obtained. The qualitative analysis of the formulas indicates the wave motion of a medium during the initial phase of operation, transitioning into a stationary mode after a brief period. The duration of the transition period depends on factors such as the hydraulic resistance coefficient and the velocity of the transported medium. Coefficient of hydraulic resistance and the velocity of the transported medium are the main factors. An example is considered for a horizontal section under isothermal flow conditions. With assumed numerical parameters, the transition to a stationary state occurs approximately 17 minutes after the process begins, as illustrated in the graphs provided in the article. Engineers can use mathematical models of the liquid and gas motion through pipes in the design of pipelines, as well as in solving tasks that arise during their operation. These tasks include monitoring the condition of the pipeline system, optimizing the operation, accumulation capacity estimates and others.

The impact of training provisions on novice English language teachers in Hong Kong: A systematic review

AbstractThe early years of learning and the transition period are important for novice teachers. This systematic review investigated the influence that training provisions for novice primary and secondary English language teachers in Hong Kong have had on their initial workplace experience. From a large body of literature dated between 1980 and 2023, a final set of 20 articles that met our inclusion criteria was analysed using Kumaravadivelu's (2012) model of second language teacher education (consisting of the five modules of Knowing, Analysing, Recognising, Doing and Seeing). The findings were condensed into three thematic strands: (i) teacher authority: novice teachers can feel lost among different authorities (including ideological conflicts between university and school authorities) and their desire to establish their own teacher authority, but must eventually learn to think from the students' perspective to improve teaching, (ii) teacher socialisation: whether obtaining sufficient colleague and mentor support or not would lead to their diverse experiences, and (iii) two weaknesses in teacher preparation that require attention across both university preparation and in‐school training: the novice teachers were under‐prepared in procedural knowledge and in learning to theorize. These findings provide internationally relevant theoretical contributions that can advance the understanding of both novice teacher development and primary and secondary English language teacher training. From a practical perspective, the findings point to areas that need attention in novice language teachers' transition to the workplace and this may be relatable to international audiences. Context and implicationsRationale for this studyThis systematic review aims to reveal how the training provisions in Hong Kong have influenced early‐year primary and secondary school English language teachers' initial workplace experience.Why the new findings matterOur findings will reveal what impact training provisions for novice English language teachers may have on their initial workplace experience and what gaps may exist in such provisions.Implications for researchers, practitioners and teacher educatorsThe findings in this study can be applied to many other contexts like Hong Kong where English is used as one of the official languages or as a second language. Our recommendations can inform English language teacher education, by highlighting: (a) how novice teachers can feel lost between two different authorities: the school and the university; (b) how novice teachers can undergo a range of positive and negative experiences in their socialisation process; (c) how novice teachers struggle to develop their procedural knowledge; and (d) that novice teachers may not have received enough support in theory‐building.

Research on the Current Status of Pension Models for Individuals with Mental Disorders in China

Objective: By analyzing the existing literature, this paper aims to explore the current situation of the pension model for patients with mental disorders in China and put forward corresponding suggestions for improvement. How: This study analyzes the current situation of the pension model for patients with mental disorders in China by referring to the views of experts and scholars, relevant cases and statistical data through the literature and review of CNKI. Focusing on the existing elderly care service system, policy support and social cognition, this paper reveals the main characteristics and existing problems of the current Chinese elderly care model for people with mental disabilities. By comparing the advanced pension models at home and abroad, this paper puts forward some suggestions on strengthening policy support and improving service system. Results: The research shows that China's existing pension models mainly include family care, institutional pension and community service. The main problems facing: insufficient service supply, shortage of professional talents, social cognition and discrimination. Home care is still the main way, more than 70% of people with mental disorders rely on home care, but face great pressure and challenges; The construction of institutional elderly care and community service systems is gradually developing, but there are still insufficient resources, low service quality, and uneven distribution between urban and rural areas. Policy suggestions: Strengthen the construction and improvement of community support system; Improve professional training to ensure service quality; Use scientific and technological means to assist the elderly and ease the shortage of human resources. It is suggested that we should strengthen the construction of community support system and improve the level of professional service in the future. Conclusion: In China, the mode of nursing care for patients with mental disorders is in the transition period, and family nursing is still the mainstream, but it also faces great challenges. Institutional care and community services have developed, but they are not yet sufficient to replace the role of the family. The future development direction should be multi-dimensional, forming a diversified and three-dimensional elderly care service network.

Identity change and the transition to university: Implications for cortisol awakening response, psychological well-being and academic performance.

The social identity model of identity change (SIMIC) posits that social group memberships protect well-being during transitional periods, such as the transition to university, via two pathways - maintaining previously held social group memberships (social identity continuity) and gaining new social group memberships (social identity gain). Breaking new ground, this study investigates how these processes can influence an important biomarker of stress - cortisol awakening response (CAR). A total of 153 first year undergraduate students (69.3% female) completed measures (group memberships, depression, life satisfaction) at the beginning of the academic year (October, time 1; T1), of which 67 provided a saliva sample for CAR assessment. Seventy-nine students completed the time 2 (February, T2) measures 4 months later (41 provided saliva). Academic performance was assessed objectively through end-of-academic year university grade data (June, T3). At T1, students who maintained and gained social group memberships reported lower depressive symptoms and greater life satisfaction. Across the academic year, social identity gain was associated with a larger post-awakening cortisol response at T2, indicative of a better ability to cope with stress. Thus, gaining new social group memberships during the transition to university was associated with a better ability to cope with stress.

Negative Problem Orientation and Wellbeing Among Emerging Adults: The Mediating Roles of Optimism and Resilience

Understanding the roles of problem orientation for wellbeing during emerging adulthood is crucial to assist this cohort in successfully navigating the challenges of the transitional period. In this context, the present study investigates the interplay between negative problem orientation (NPO), resilience, optimism, and wellbeing among emerging adults. For this cross-sectional study, NPO, optimism, resilience, and wellbeing scales were administered to a total of 355 emerging adults (77% female, Mage= 21.33, SD = 2.35). The results revealed that NPO both directly and indirectly predicted wellbeing through optimism. However, contrary to the common assumption about positive outcomes of resilience, no significant mediating effects of resilience between NPO and wellbeing were observed. The study concludes with a discussion of both theoretical and practical implications of the findings.

Comparing peripheral limb and forehead vital sign monitoring in newborn infants at birth.

To study the feasibility of measuring heart rate (HR) and oxygen saturation (SpO2) on the forehead, during newborn transition at birth, and to compare these measurements with those obtained from the wrist. Vital signs were measured and compared between forehead-mounted reflectance (remittance) photoplethysmography sensor (fhPPG) and a wrist-mounted pulse oximeter sensor (wrPO), from 20 enrolled term newborns born via elective caesarean section, during the first 10 min of life. From the datasets available (n = 13), the median (IQR) sensor placement times for fhPPG, ECG and wrPO were 129 (70) s, 143 (68) s, and 159 (76) s, respectively, with data recorded for up to 10 min after birth. The success rate (percentage of total possible HR values reported once sited) of fhPPG (median = 100%) was higher compared to wrPO (median = 69%) during the first 6 min of life (P < 0.005). Both devices exhibited good HR agreement with ECG, achieving >95% agreement by 3 (fhPPG) and 4 (wrPO) min. SpO2 for fhPPG correlated with wrPO (r = 0.88), but there were significant differences in SpO2 between the two devices between 3 and 8 min (P < 0.005), with less variance observed with fhPPG SpO2. In the period of newborn transition at birth in healthy term infants, forehead measurement of vital signs was feasible and exhibited greater HR accuracy and higher estimated SpO2 values compared to wrist-sited pulse oximetry. Further investigation of forehead monitoring based on the potential benefits over peripheral monitoring is warranted. This study demonstrates the feasibility of continuously monitoring heart rate and oxygen saturation from an infant's forehead in the delivery room immediately after birth. Significantly higher SpO2 measurements were observed from the forehead than the wrist during the transition from foetal to newborn life. Continuous monitoring of vital signs from the forehead could become a valuable tool to improve the delivery of optimal care provided for newborns at birth.

Effects of rumen-protected methionine and lysine on antioxidant status and lactationperformance in crossbred dairy cattle during transition

Dairy cows undergoing the transition phase often face nutritional challenges, impacting their antioxidant status and lactational performance. To address these challenges, the incorporation of rumen-protected methionine and lysine in the diet has emerged as a strategic intervention.Twelve crossbred cows inthe transition period were randomly divided into two groups of six animals. The control group and treatment group were fed with a standard diet (ICAR, 2013) while the treatment group was supplemented with rumen-protected methionine and lysine. Throughout the trial period, all the animals were subjected to consistent management and feeding conditions.Glutathione peroxide(GPx)levels exhibited a statistically significant difference between groups, with the treatment consistently showing higher GPx levels, indicating an improvement in antioxidant capacity, where it helps regulate systemic oxidative stress.The recorded milk yield data was utilized to compute the daily milk production for each individual for the experimental period. Milk yield remained unaffected, but the treatment group consistently exhibited higher milk yield, suggesting positive influences on postpartum lactation performance. Keywords: Rumen-protectedmethionine, rumen-protectedlysine,transition period, antioxidant status

Experiences of Intensive Care Unit Patients as They Transition to the Ward: A Thematic Synthesis.

During the transfer of intensive care unit (ICU) patients to general wards, patients often experience transfer anxiety due to changes in the healthcare environment, staff and unfamiliarity with the new ward. However, the experiences of ICU patients during this transition period have received less attention. A systematic review and synthesis of the experiences of patients transitioning from the ICU to the ward. Thematic synthesis of qualitative studies. We searched the PubMed, Embase, CINAHL and Web of Science databases for qualitative research on the transition-to-ward experience of patients in ICUs for the year 2023 February. The quality of the literature was evaluated according to the qualitative research quality assessment criteria of the Joanna Briggs Institute, as outlined by the Australian Centre for Evidence-Based Healthcare. The data were then extracted from the studies, analysed and synthesised using a thematic synthesis approach. A total of 12 papers were included and the 32 findings were distilled and consolidated into three themes: emotional reactions; imperfections in the transition process; differences between wards and ICUs; and eight sub-themes: optimism; pessimism; emotionlessness; inadequate information; inadequate communication; physical condition; differences in care; differences in environment. The transfer from an ICU to a general ward is a major change of environment for the patient and can trigger upset and anxiety. Planning for turn-out, meeting patients' information needs and easing patients' emotions are critical in this process.

Role of midtropospheric heating and surface forcing on monsoon intraseasonal transitions

AbstractMonsoon intraseasonal transitions are intrinsically chaotic; hence, their predictability is limited. In the past the majority of studies were conducted solely keeping in account of dynamic prospective like boreal summer intraseasonal oscillation or Madden–Julian oscillation; however its thermodynamic aspect got limited attention. The current study looks at the internal thermodynamic mechanisms pertaining to monsoon intraseasonal transition using two independent sets of reanalysis data (European Centre for Medium‐range Weather Forecasts Reanalysis version 5 and Indian Monsoon Data Assimilation and Analysis), along with the observed cloud type from Met Office Integrated Data Archive System Land and Marine surface station data. A lead–lag composite analysis shows that the midtropospheric warming by diabatic heating is a thermal control to restrict the deepening of convective cloud (cumulonimbus) as the wet spell progresses. This midtroposhperic heating cuts off the formation of deep convective clouds and results in the formation of relatively shallow clouds, such as stratocumulus and stratus. On the other hand, surface forcing during dry spells humidifies the troposphere by detrainment from the shallow convection with the formation of cumulus and cumulus congestus clouds. This facilitates the preconditioning of the atmosphere for deep convection and results in the onset of wet spells by the formation of cumulonimbus clouds. The comprehensive approach used in this work may further help in identifying the limitation of the predictability in monsoon transition period from the numerical weather prediction models.

BALANCED NUTRITION EDUCATION AND NUTRITIONAL STATUS SCREENING OF MALE ADOLESCENTS IN DORMITORY

Introduction: Adolescence is a golden period of reproductive, psychological and intelligence development. During the transition period between childhood and adulthood, biological, emotional, social and cognitive changes occur. Fulfilling nutrition during this period is important. This activity aims to educate teenagers about balanced nutrition and screen their nutritional status. Methods: This community service activity is carried out by providing education about balanced nutrition through lecture and discussion methods. While screening the nutritional status of adolescents is done through anthropometric measurements of body weight and height. The results of anthropometric measurements were then processed using the BMI formula according to age to obtain a z-score that describes the nutritional status of adolescents. This activity was carried out in dormitory of a high school with 36 young male participants. Results: Based on verbal observation and evaluation, students can receive and understand the material about balanced nutrition that is given properly. The results of the nutritional status screening showed that 31 of the adolescents in this activity (86%) had good nutrition but there were still students who had problems with thinness (3%), overweight (8%) and obesity(3%). Conclusion: It is recommended that schools and boarding schools follow up on students who are not in the good nutrition category. Students are directed to consume a balanced diet and physical activity so as to achieve the ideal body weight according to their height and age.

Gene Enrichment and Pathway Analysis for Ketosis Resistance in Dairy Cattle: A GWAS-Based Approach

Ketosis in dairy cattle is a common metabolic disorder that arises during the transition period from late gestation to early lactation. It is primarily caused by an imbalance between energy intake and expenditure, leading to an excessive accumulation of ketone bodies. This condition can significantly affect cattle health and productivity. Recent advances in genomic research, especially genome-wide association studies (GWAS), offer an opportunity to explore the genetic factors that contribute to ketosis resistance. The aim of this study is to comprehensively review and analyze existing GWAS data using gene enrichment analysis to identify potential functional candidate gene pathways associated with ketosis resistance in dairy cattle. In this study, data obtained from seven different studies were examined and 640 non-repetitive genes were obtained after filtering. Using Enrichr, an online tool for gene annotation, pathway analysis was performed with human homologs of the identified genes. Our findings highlight the acylglycerol homeostasis pathway, the regulation of triglyceride metabolism, and the role of chylomicrons in maintaining metabolic balance during ketosis. Additionally, immune response pathways were found to be linked to the genes associated with ketosis, offering insights into the intricate interplay between metabolic and immune pathways in ketosis. This study emphasizes the importance of understanding genetic factors in developing breeding strategies aimed at enhancing metabolic health and productivity in dairy cattle. Future research should focus on validating these candidate genes and exploring their mechanistic roles to facilitate targeted interventions and improve resistance to ketosis in dairy herds.

Development and validation of a dynamic nomogram for high care dependency during the hospital-family transition periods in older stroke patients

BackgroundThis research aimed to develop and validate a dynamic nomogram for predicting the risk of high care dependency during the hospital-family transition periods in older stroke patients.Methods309 older stroke patients in the hospital-family transition periods who were treated in the Department of Neurology outpatient clinics of three general hospitals in Jinzhou, Liaoning Province from June to December 2023 were selected as the training set. The patients were investigated with the General Patient Information Questionnaire, the Care Dependency Scale (CDS), the Tilburg Frailty Inventory (TFI), the Hamilton Anxiety Rating Scale (HAMA), the Hamilton Depression Rating Scale-17 (HAMD-17), and the Mini Nutrition Assessment Short Form (MNA-SF). Lasso-logistic regression analysis was used to screen the risk factors for high care dependency in older stroke patients during the hospital-family transition period, and a dynamic nomogram model was constructed. The model was uploaded in the form of a web page based on Shiny apps. The Bootstrap method was employed to repeat the process 1000 times for internal validation. The model’s predictive efficacy was assessed using the calibration plot, decision curve analysis curve (DCA), and area under the curve (AUC) of the receiver operator characteristic (ROC) curve. A total of 133 older stroke patients during the hospital-family transition periods who visited the outpatient department of Neurology of three general hospitals in Jinzhou from January to March 2024 were selected as the validation set for external validation of the model.ResultsBased on the history of stroke, chronic disease, falls in the past 6 months, depression, malnutrition, and frailty, build a dynamic nomogram. The AUC under the ROC curves of the training set was 0.830 (95% CI: 0.784–0.875), and that of the validation set was 0.833 (95% CI: 0.766-0.900). The calibration curve was close to the ideal curve, and DCA results confirmed that the nomogram performed well in terms of clinical applicability.ConclusionThe online dynamic nomogram constructed in this study has good specificity, sensitivity, and clinical practicability, which can be applied to senior stroke patients as a prediction and assessment tool for high care dependency. It is of great significance to guide the development of early intervention strategies, optimize resource allocation, and reduce the care burden on families and society.

Oxygenation associated with cord management strategies among preterm infants

Compare changes in SpO2 and FiO2 post-birth among preterm infants after delayed cord clamping (DCC), umbilical cord milking (UCM) or early cord clamping (ECC). Retrospective study of infants <32 weeks gestation born between 2014 and 2021. ECC was clamping 0-59 s, DCC was clamping ≥60 s after delivery, UCM defined as milking the intact umbilical cord several times before clamping. Of 463 infants; 257 received DCC, 168 received UCM, 38 received ECC. UCM infants had higher median SpO2 values at 4-(79% UCM vs 69% DCC, p = 0.027) and 5-(85% UCM vs 80% DCC, p = 0.023) minutes after-birth compared to DCC. DCC and UCM infants required lower FiO2 levels in the first 5-minutes compared to ECC infants (DCC 0.38 ± 0.17, UCM 0.40 ± 0.20 vs ECC 0.51 ± 0.27, p's <0.001). The proportion of infants achieving SpO2 ≥ 80% by 5 min was similar in all groups, FiO2 needed to achieve this goal was higher in ECC infants.

A Longitudinal Examination between Chronotype and Insomnia in Youths: A Cross-Lagged Panel Analysis.

Adolescence and young adulthood are transitional periods associated with significant changes and challenges, leading to a heightened vulnerability to sleep disturbances and mental health difficulties. This stage is often associated with an increased preference for eveningness, manifested as a later chronotype. The current study aimed to investigate the directionality of the association between chronotype, based on an individual's sleep-wake behaviour, and insomnia in young people using a two-wave panel design with a 12-month interval. A total of 370 participants aged 15-24 (mean age: 21.0 ± 2.0, 72.7% female) were recruited from local secondary schools and universities. Insomnia symptoms were assessed using the Insomnia Severity Index, while chronotype was measured using the Munich Chronotype Questionnaire. Temporal associations were analysed using a series of cross-lagged panel models. The best fitting and most parsimonious model indicated that a later chronotype at baseline predicts more severe insomnia symptoms at the 12-month follow-up after accounting for autoregressive effects. However, the opposite causal model, where baseline insomnia symptoms predicted the chronotype at the 12-month follow-up, was not supported. These findings suggest that a late chronotype may be a potential risk factor for the development of insomnia in young people, emphasising the importance of considering circadian factors in the prevention and treatment of sleep disturbances among this population.
