Objective:To explore the relationship between irrational procrastination and compulsory citizenship behavior among clinical nurses,and to investigate the role of psychological entitlement in this relationship.Meth-ods:A sample of 413 clinical nurses from a tertiary hospital was selected for this study.The Irrational Procrastina-tion Scale(IPS),Compulsory Citizenship Behavior Scale(CCBS),and Psychological Entitlement Scale(PES)were used for evaluation.Results:The scores of IPS,CCBS and PES were positively correlated with each other(r=0.53,0.56,0.39,Ps＜0.01).Psychological entitlement partially mediated the relationship between compulsory citi-zenship behavior and irrational procrastination among clinical nurses,with an indirect effect of 0.17,accounting for 13.85％of the total effect.Conclusion:Psychological entitlement plays a partial mediating role in the relationship between compulsory citizenship behavior and irrational procrastination among clinical nurses.

Objective·To analyze the influencing factors of left ventricular mass index(LVMI)in patients with essential hypertension,and explore the relationship between aldosterone levels and left ventricular hypertrophy(LVH).Methods·A total of 155 patients with essential hypertension,hospitalized in the Hypertension Department of the Northern Campus of Ruijin Hospital,Shanghai Jiao Tong University School of Medicine,from January 2013 to December 2019,and excluded from primary aldosteronism by saline load test(post-saline suppression plasma aldosterone<60 pg/mL),were enrolled.General clinical data(age,gender,smoking status,duration of hypertension,etc.),physical examination data(blood pressure and body mass index),blood biochemistry(renal function,electrolytes,fasting blood glucose,and lipids),urinary sodium,and relevant hormones(basal and activated aldosterone,basal and activated renin,urinary aldosterone,post-saline suppression aldosterone,etc.)were collected.LVMI was evaluated by echocardiography.Pearson correlation analysis was used to assess the linear association between LVMI and each variable.Binary Logistic regression models were applied to screen independent risk factors for LVH.Multiple linear regression models were used to assess the impact of variables on LVMI.Results·The mean age of the 155 patients was(46.85±11.08)years,with 51.6%being male.Pearson correlation analysis showed that LVMI was significantly positively correlated with post-saline suppression aldosterone(r=0.334,P<0.001),age(r=0.184,P=0.032),duration of hypertension(r=0.241,P=0.005),systolic blood pressure(r=0.280,P=0.001),and pulse pressure(r=0.339,P<0.001).No significant correlations were found with diastolic blood pressure,body mass index,fasting blood glucose,total cholesterol,low-density lipoprotein cholesterol,triglyceride,high-density lipoprotein cholesterol,urinary sodium,basal aldosterone,activated aldosterone,or urinary aldosterone.After adjusting for confounders,including gender,smoking history,age,duration of hypertension,body mass index,pulse pressure,systolic blood pressure,fasting blood glucose,and total cholesterol,binary Logistic regression showed that each 1 pg/mL increase in post-saline suppression aldosterone was associated with a 5.1%increased risk of LVH(OR=1.051,95%CI 1.016?1.088,P=0.004).Multiple linear regression identified suppressed aldosterone(β=0.359,P<0.001),duration of hypertension(β=0.168,P=0.046),and pulse pressure(β=0.226,P=0.008)as independent influencing factors for LVMI.Conclusion·Suppressed aldosterone is an independent influencing factor for LVH in patients with essential hypertension.

Objective To propose a multiple regression-variational auto-encoders(MR-VAE)model to realize precise and non-invasive prediction of intra-abdominal pressure(IAP)in critically ill patients.Methods At first,a dataset was constructed by retrospectively analysing baseline characteristics and clinical indicators of 100 critically ill patients admitted to the Intensive Care Unit of Daping Hospital of Army Medical University between 30 August 2019 and 30 March 2021.Then,a MR-VAE prediction model was developed by integrating a feedforward neural network for supervised regression onto a variational autoencoder(VAE)framework and incorporating multiple regression strategies to mitigate feature interference.Finally,the MR-VAE model had its performance evaluated by its comparison with five classical models including support vector machines(SVM),convolutional neural networks(CNN),Scikit-learn integrated model(SIM),multi-layer perceptron(MLP)and K-nearest neighbors(KNN),and its prediction accuracy verified by testing the data of 10 randomly selected patients.Results The MR-VAE model behaved the best when compared with the five classical models,with a mean squared error(MSE)of 0.207,a root mean square error(RMSE)of 0.454,a mean absolute error(MAE)of 0.361,a median absolute deviation(MAD)of 0.243,an explained variance score(EVS)of 0.814 and a R2of 0.823,which also outperformed the five models in fitting performance,convergence and final loss.In random sample testing,the MR-VAE model exhibited high consistency between predicted and actual values.Conclusion The MR-VAE model proposed can accurately predict IAP,which has great potential in reducing the repeated measurements of IAP in critically ill patients and providing new ideas for the early diagnosis and treatment of IAH.

Objective: Negative symptoms in schizophrenia indicate a poor prognosis. However, the mechanisms underlying the development of negative symptoms remain unclear. This study investigated the relationship between negative symptoms in schizophrenia and frontal alpha asymmetry (FAA). Methods: The study used a 32-channel electroencephalography to acquire alpha power in 4 target-paired sites in each patient. Regional alpha asymmetry was calculated based on the alpha power using EEGLAB Frontal Alpha Asymmetry Toolbox. Results: Sixty schizophrenia patients with predominant negative symptoms (PNS), 72 stabilized schizophrenia (SS) patients, and 73 healthy control (HC) participants were enrolled in this study. No significant differences were observed in FAA between the PNS and SS groups, although both groups exhibited reduced P3-P4 alpha asymmetry compared to HCs. A positive correlation was found between F7-F8 alpha asymmetry and illness duration. Additionally, a predictive model based on P3-P4 alpha asymmetry scores was able to differentiate schizophrenia patients from HCs, achieving a sensitivity of 71.2% and a specificity of 72.6%. Conclusion This study highlighted that parietal alpha asymmetry could serve as a valuable diagnostic tool for schizophrenia.

Purpose: Intertrochanteric fractures often involve comminuted fractures, particularly around the intertrochanteric ridge, including the greater and lesser trochanters. In cases with comminuted fractures in the posterior region, maintaining a stable reduction of the anteriormedial region of the fracture surface is essential. Therefore, this study examined the morphologic features of the anterior femur for stable reduction by analyzing the anterior region of intertrochanteric fractures using three-dimensional computed tomography. Materials and Methods: This retrospective study analyzed the imaging data of 51 patients aged 60 years and older who underwent a surgical treatment for intertrochanteric fractures at a single institution from April 2013 to March 2023. The sample contained 15 male patients with an average age of 81.9 years and 36 female patients with an average age of 83.7 years. Forty patients (78.4%) had two or more comorbidities. The bone mineral density was assessed in all cases except for five (9.8%). Results: In 49 cases (96.1%), the anterior fracture line followed the intertrochanteric line and passed through two bony prominences.In two cases (3.9%), the fracture line ran below the intertrochanteric line and involved a large fragment of the lesser trochanter. As the fracture line passed through the inferior medial bony prominence, it exhibited an S-shaped pattern rather than a straight line. The inferior medial bony prominence consisted of cortical bone, with an average thickness of 6.4±1.4 mm, which was significantly thicker than the surrounding average cortical bone thickness (1.5±0.6 mm) but thinner than the cortical bone thickness of the femoral shaft (7.3±1.3 mm).The fracture line in the superior lateral region of the intertrochanteric line included cancellous bone with a cortical bone thickness of 1.1±0.6 mm, which was thin. Conclusion The anterior fracture line followed the femoral intertrochanteric line and curves as it passed through the inferior medial bony prominence. The inferior medial bony prominence, consisting of cortical bone, was significantly thicker than the surrounding average cortical bone.

Background: Active surveillance (AS) has emerged as a viable management strategy for low-risk papillary thyroid microcarcinoma (PTMC), following pioneering trials at Kuma Hospital and the Cancer Institute Hospital in Japan. Numerous prospective cohort studies have since validated AS as a management option for low-risk PTMC, leading to its inclusion in thyroid cancer guidelines across various countries. From 2016 to 2020, the Multicenter Prospective Cohort Study of Active Surveillance on Papillary Thyroid Microcarcinoma (MAeSTro) enrolled 1,177 patients, providing comprehensive data on PTMC progression, sonographic predictors of progression, quality of life, surgical outcomes, and cost-effectiveness when comparing AS to immediate surgery. The second phase of MAeSTro (MAeSTro-EXP) expands AS to low-risk papillary thyroid carcinoma (PTC) tumors larger than 1 cm, driven by the hypothesis that overall risk assessment outweighs absolute tumor size in surgical decision-making. Methods: This protocol aims to address whether limiting AS to tumors smaller than 1 cm may result in unnecessary surgeries for low-risk PTCs detected during their rapid initial growth phase. By expanding the AS criteria to include tumors up to 1.5 cm, while simultaneously refining and standardizing the criteria for risk assessment and disease progression, we aim to minimize overtreatment and maintain rigorous monitoring to improve patient outcomes. Conclusion This study will contribute to optimizing AS guidelines and enhance our understanding of the natural course and appropriate management of low-risk PTCs. Additionally, MAeSTro-EXP involves a multinational collaboration between South Korea and Australia. This cross-country study aims to identify cultural and racial differences in the management of low-risk PTC, thereby enriching the global understanding of AS practices and their applicability across diverse populations.

INTRODUCTION: Obstructive sleep apnoea (OSA) is common in Singapore, with moderate to severe OSA affecting around 30% of residents. These consensus statements aim to provide scientifically grounded recommendations for the management of OSA, standar-dise the management of OSA in Singapore and promote multidisciplinary collaboration. METHOD: An expert panel, which was convened in 2024, identified several areas of OSA management that require guidance. The expert panel reviewed the current literature and developed consensus statements, which were later independently voted on using a 3-point Likert scale (agree, neutral or disagree). Consensus (total ratings of agree and neutral) was set a priori at ≥80% agreement. Any statement not reaching consensus was excluded. RESULTS: The final consensus included 49 statements that provide guidance on the screening, diagnosis and management of adults with OSA. Additionally, 23 statements on the screening, diagnosis and management of paediatric OSA achieved consensus. These 72 consensus statements considered not only the latest clinical evidence but also the benefits and harms, resource implications, feasibility, acceptability and equity impact of the recommendations. CONCLUSION The statements presented in this paper aim to guide clinicians based on the most updated evidence and collective expert opinion from sleep specialists in Singapore. These recommendations should augment clinical judgement rather than replace it. Management decisions should be individualised, taking into account the patient's clinical characteristics, as well as patient and caregiver concerns and preferences.
