Long-term mortality and associated factors in first episode psychosis: a 25-year follow-up study

Psychol Med. 2025 Nov 21;55:e355. doi: 10.1017/S0033291725102286.

ABSTRACT

BACKGROUND: Individuals with first-episode psychosis (FEP) face markedly increased excess mortality, yet the long-term trends and key contributing factors remain insufficiently characterized. This study aimed to examine long-term mortality patterns, standardized mortality ratios (SMRs), and associated factors in a FEP cohort.

METHODS: This population-based cohort study included 1,389 individuals diagnosed with FEP, followed for up to 25 years. Mortality outcomes were obtained from Hong Kong’s centralized hospital database (CMS) and coroner’s court reports, with SMRs calculated. Baseline sociodemographic and clinical, as well as long-term treatment-related factors of all-cause, natural, and unnatural mortality were analyzed.

RESULTS: Among 1,389 participants, 137 deaths (9.86%) occurred during the follow-up period with the overall SMR of 6.56 (95% CI, 5.50-7.71). The cumulative incidence rate of unnatural mortality increased sharply over the first 10 years and that of the natural cause of death started to increase after the first decade of the illness. Male gender and poorer social functioning were associated with increased all-cause mortality risk, while male gender, lower education, and baseline hospitalization raised unnatural mortality risk. Greater monthly antipsychotic variability during the first 10 years increased all-cause mortality risk in the period after the initial 10 years.

CONCLUSIONS: This 25-year follow-up study of FEP highlighted the changes in the long-term mortality pattern of FEP and thus the phase-specific needs of individuals with FEP. Therefore, it is important to integrate physical care into mental health services, as well as stage-specific and individualized care for patients with psychotic disorders to reduce long-term excess mortality.

Exclusion and Truancy of Autistic Adolescents in a UK Population Representative Sample

Child Care Health Dev. 2025 Nov;51(6):e70187. doi: 10.1111/cch.70187.

ABSTRACT

BACKGROUND: Autistic students experience many problems with school attendance. School exclusion and truancy are among the least researched school attendance problems in this population. The study aimed to describe levels of exclusion and truancy in a UK population-representative sample of autistic adolescents and identify child, family and school factors associated with each school attendance problem.

METHODS: Data were drawn from the Millennium Cohort Study where exclusion and truancy information was available for 460 autistic 14-year-olds. Descriptive statistics were used to report the weighted prevalence of exclusion and truancy. A bio-ecological framework guided the selection of available child, family and school factors potentially associated with exclusion and truancy for modelling. Univariable and multivariable logistic regression models were fitted to investigate associations.

RESULTS: Twenty-five percent of autistic adolescents were temporarily or permanently excluded at least once. Fifteen percent of autistic adolescents reported truanting at least once. Externalising problems were strongly associated with higher odds of exclusion and truancy. The level of school support was strongly associated with higher odds of exclusion. There was weak evidence of an association between exclusion and low parental school engagement and between truancy and the absence of intellectual impairment.

CONCLUSION: Poor mental health and in particular externalising difficulties seem to be strongly associated with a greater likelihood of parent-reported exclusion and adolescent-reported truancy. The role of school support and adaptation to the child’s needs warrants further investigation.

A Phase 1 study of the safety, tolerability, and pharmacokinetics of ALG-000184 (pevifoscorvir sodium), a novel Class E capsid assembly modulator, in healthy participants

Antivir Ther. 2025 Dec;30(6):13596535251392955. doi: 10.1177/13596535251392955. Epub 2025 Nov 21.

ABSTRACT

BackgroundClass E (empty) capsid assembly modulators (CAM-Es) inhibit HBV capsid assembly, pregenomic RNA encapsidation preventing formation the establishment of covalently closed circular HBV DNA (ccDNA). ALG-000184 (pevifoscorvir sodium), is a prodrug of the Class E CAM ALG-001075.MethodsALG-000184-201 was a Phase 1 randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability and pharmacokinetics of ALG-000184. Healthy participants (n = 8/cohort) received oral single-ascending doses (SAD) of ALG-000184 (40, 100, 250, and 500 mg) or placebo, and multiple-ascending daily doses (MAD) (150 mg and 250 mg) or placebo for 7 days.ResultsALG-000184 was well tolerated by 48 participants who received single doses up to 500 mg and multiple daily doses up to 250 mg for 7 days. ALG-000184 was rapidly converted to the active moiety, ALG-001075. ALG-001075 had dose-proportional increase in plasma exposure, low-to-moderate variability (18%-34% CV for AUC0-24), rapid absorption (median tmax 1-3.5 h), and biphasic distribution/elimination with terminal t½ 7-8 h and minimal accumulation (∼30%). A major oxidative metabolite, ALG-000302, was identified in plasma (∼17%-24% of ALG-001075). A high-fat/high-calorie meal did not significantly impact the plasma pharmacokinetics. No differences in pharmacokinetics between Asian and non-Asian participants were observed. A concentration QT analysis indicated no statistically significant change in ΔΔQTcF with plasma ALG-001075. Urinary excretion of ALG-001075 was low following single or multiple ALG-000184 doses.ConclusionsALG-000184 demonstrated good tolerability, safety and pharmacokinetic properties in healthy participants. The pharmacokinetic profile suggests that a daily dose of 100 mg or higher will provide efficacious exposures in patients with chronic HBV infection.Clinical trial numberNCT04536337 (https://clinicaltrials.gov/study/NCT04536337).

Phytoremediation effect of metal-mobilizing bacteria on growth promotion and nutrient uptake of Populus deltoides under controlled conditions

Int J Phytoremediation. 2025 Nov 21:1-14. doi: 10.1080/15226514.2025.2585364. Online ahead of print.

ABSTRACT

Plant-colonizing beneficial microbes are effective bio-tools for enhancing phytoremediation. Two-year pot experiment at Punjab Agricultural University, Ludhiana, India, assessed the response of Populus deltoides under nursery conditions to sewage sludge treated soil with indigenous metal-mobilizing Bacillus species-B. thuringiensis (T1), B. cereus (T2), B. pumilus (T3), and their consortium (T4), with three inorganic fertilizer levels-RDF1-100%, RDF2-75%, and RDF3-50% [Recommended dose of fertilizer (RDF)]. Each inoculated treatment was compared to its respective uninoculated control (C). The application of T4 with RDF1 significantly increased shoot length and biomass by 13.8 and 32.9% than C, respectively. Bioconcentration factors (BCF) for Cd and Ni increased by over 50% than C demonstrating enhanced phytoremediation efficiency. Elemental accumulation was predominantly localized in roots, with the exception of Zn and Cd. Among most of the parameters, RDF1 × T4 was statistically comparable with RDF2 × T4. Irrespective of fertilizer dose, T4 maximally improved phytoremediation efficiency (BCF) by 0.61 (shoot) and 0.52 (root) compared to 0.20 and 0.16 in C, respectively, as well as soil chemical and biological properties up to 22.3%. These results highlight the potential of indigenous microbial inoculants to reduce soil heavy metals and enable sustainable, enhanced phytoremediation with 25% lower fertilizer input.

Stress Management and Resilience Training on Nursing Undergraduates in Hong Kong: A Feasibility Study

J Child Adolesc Psychiatr Nurs. 2025 Nov;38(4):e70045. doi: 10.1111/jcap.70045.

ABSTRACT

BACKGROUND: Resilience, the ability to adapt and thrive under adversity, is essential for nursing students vulnerable to stress, burnout, and psychological distress. Strengthening resilience may protect well-being and enhance patient care.

METHODS: This feasibility study employed a one-group pretest-posttest design. A face-to-face stress management and resilience training (SMART) programme was delivered to 40 nursing undergraduates at a self-financing institution in Hong Kong. Resilience and stress were measured at baseline (T0), 2 weeks (T1), and 3 months (T2) using the Connor-Davidson Resilience Scale-10 (CD-RISC-10) and Perceived Stress Scale-10 (PSS-10). A post-training satisfaction survey was also conducted.

RESULTS: Thirty-one participants completed all assessments. CD-RISC-10 scores increased significantly from 22.00 (SD = 4.11) at T0 to 27.81 (SD = 7.39) at T1 and 26.42 (SD = 6.45) at T2. Improvements were significant between T0-T1 (p < 0.001) and T0-T2 (p = 0.004). PSS-10 scores declined slightly (18.61 at T0 to 17.65 at T2) but without statistical significance (p = 0.123). Satisfaction ratings were high (mean 5.38-5.60/6), particularly for trainer performance and content.

CONCLUSION: The SMART programme was feasible, well-received, and effective in improving resilience among Hong Kong nursing undergraduates. Findings support its potential integration into undergraduate nursing curricula.

Generalized nonparametric temporal modeling of recurrent events with application to a malaria vaccine trial

Biometrics. 2025 Oct 8;81(4):ujaf146. doi: 10.1093/biomtc/ujaf146.

ABSTRACT

Motivated by a malaria vaccine efficacy trial, this paper investigates generalized nonparametric temporal models of intensity processes with multiple time scales. Through the choice of link functions, the proposed models encompass a wide range of models such as the multiplicative temporal intensity model and the additive temporal intensity model. A maximum likelihood estimation procedure is developed to estimate the effects of two time-scales via the local linear smoothing with double kernels. Computational algorithms are developed to facilitate applications of the proposed method. An adaptive algorithm is developed to overcome the challenges of overlapping covariates. A cross-validation bandwidth selection procedure based on the logarithm of likelihood criteria is discussed. The asymptotic properties of the proposed estimators are investigated. Our simulation study shows that the proposed methods have satisfactory finite sample performance for both the multiplicative temporal intensity model and additive temporal intensity model. The proposed methods are applied to analyze the MAL-094/MAL-095 malaria vaccine efficacy trial data to investigate how the new malaria infection risk changes over time and how a prior infection or vaccination changes the future infection risk. The proposed method provides new insight into the protective effects of the malaria vaccine against new malaria infections and how the vaccine efficacy is modified by the history of prior malaria infection over time.

Federated double machine learning for high-dimensional semiparametric models

Biometrics. 2025 Oct 8;81(4):ujaf150. doi: 10.1093/biomtc/ujaf150.

ABSTRACT

Federated learning enables the training of a global model while keeping data localized; however, current methods face challenges with high-dimensional semiparametric models that involve complex nuisance parameters. This paper proposes a federated double machine learning framework designed to address high-dimensional nuisance parameters of semiparametric models in multicenter studies. Our approach leverages double machine learning (Chernozhukov et al., 2018a) to estimate center-specific parameters, extends the surrogate efficient score method within a Neyman-orthogonal framework, and applies density ratio tilting to create a federated estimator that combines local individual-level data with summary statistics from other centers. This methodology mitigates regularization bias and overfitting in high-dimensional nuisance parameter estimation. We establish the estimator’s limiting distribution under minimal assumptions, validate its performance through extensive simulations, and demonstrate its effectiveness in analyzing multiphase data from the Alzheimer’s Disease Neuroimaging Initiative study.

Factors Affecting the Frequency of Maxillofacial Injuries in Jahrom, Iran

J Dent (Shiraz). 2025 Dec 1;26(4):317-324. doi: 10.30476/dentjods.2025.105054.2566. eCollection 2025 Dec.

ABSTRACT

BACKGROUND: Maxillofacial trauma constitutes a major public health concern due to its potential for severe complications and substantial impact on quality of life.

PURPOSE: This study aimed to elucidate the factors influencing the occurrence of maxillofacial trauma in patients presenting with traumatic injuries at Peymaniyeh Hospital in Jahrom, Iran.

MATERIALS AND METHOD: This cross-sectional study examined trauma patients at Peymaniyeh Hospital in Jahrom, Iran, from April 2022 to March 2023. A census approach included all trauma patients whose data were recorded in the National Trauma Registry of Iran. Data were collected using a tailored checklist that captured demographic and contextual variables along with injury mechanisms. Statistical analyses were performed using SPSS version 22.

RESULTS: Of 924 trauma patients, 218 were diagnosed with maxillofacial trauma and 706 with non-maxillofacial trauma. The majority of the trauma patients were male (76.4%), and the distribution of age groups was not statistically different between the two types of injuries (p= 0.571). Univariate analysis revealed that substance (p= 0.007) and alcohol use (p< 0.001), road traffic accidents (RTAs) (p= 0.001), and representation of motorcyclists (p= 0.001) were significantly more prevalent in maxillofacial injury compared to non-maxillofacial injury category. Logistic regression analysis revealed that substance use (OR= 2.04, 95% CI 1.03-3.99, p= 0.040), alcohol consumption (OR= 2.89, 95% CI 1.37-6.09, p= 0.005), and experiencing RTAs (OR= 12.80, 95% CI 6.07-26.98, p< 0.001) and falling (OR= 3.69, 95% CI 1.68-8.11, p= 0.001) were significantly associated with the occurrence of maxillofacial injuries.

CONCLUSION: This study underscores the prominence of RTAs, particularly those involving motorcyclists, as a primary cause of maxillofacial injuries. The significant association between alcohol and substance use and the elevated risk of these injuries is evident. These findings highlight the need for targeted prevention strategies to promote safe driving practices, and implement public health policies aimed at mitigating alcohol and substance use disorder to reduce the incidence of such injuries.

Evaluating Calcium Hydroxide Removal Techniques in Endodontics: A Comparative Analysis

J Dent (Shiraz). 2025 Dec 1;26(4):325-335. doi: 10.30476/dentjods.2025.103049.2416. eCollection 2025 Dec.

ABSTRACT

BACKGROUND: Endodontic therapy plays a pivotal role in dentistry, with effective removal of intracanal medications crucial for successful treatment. The lingering presence of calcium hydroxide within dentinal walls can impede sealer adhesion and compromise treatment outcomes.

PURPOSE: This study aimed to compare the efficacy of various methods for removing calcium hydroxide from different regions of the root canal wall.

MATERIALS AND METHOD: In this in vitro randomized trial study, 108 extracted teeth underwent canal cleaning and shaping using the Dentsply Protaper Gold rotary system. Subsequently, except for the negative control group, all teeth were filled with calcium hydroxide and divided into eight groups. These groups underwent different cleaning protocols involving Gentle Brush or Gentlefile #021 files or master apical file in combination with ethylene-diamine-tetra-acetic acid or sodium hypochlorite solutions. After tooth splitting, stereomicroscopic images were taken, and Digimizer software was utilized to calculate residual calcium levels in coronal, middle, and apical regions. Mann-Whitney test was used to check the effect of the cleaning method and type of washing solution among the methods employed. All the analyses were conducted using SPSS 22.

RESULTS: The results indicated that the Gentle Brush method’s superior efficacy in calcium hydroxide removal compared to other files, which was statistically significant (p Value <0.01). Similarly, the ethylene-diamine-tetra-acetic acid rinse solution proved more effective than sodium hypochlorite in clearing calcium hydroxide from the canal wall (p< 0.05).

CONCLUSION: The findings suggest that a Gentle Brush combined with an ethylene-diamine-tetra-acetic acid washing solution represents the most effective method for canal cleaning and calcium hydroxide removal. This study underscores the importance of employing efficient techniques to enhance treatment quality in endodontic practice.

Assessment of Some Trace Metals in Head and Neck Squamous Cell Carcinoma: A Case-Control Study

J Dent (Shiraz). 2025 Dec 1;26(4):309-316. doi: 10.30476/dentjods.2025.104402.2534. eCollection 2025 Dec.

ABSTRACT

BACKGROUND: Micronutrients and trace elements have been linked to the development of head and neck squamous cell carcinoma (HNSCC). However, the role of these elements in the etiology of HNSCC remains unclear.

PURPOSE: This study was conducted to investigate the association between micronutrient and trace element levels and the risk of HNSCC.

MATERIALS AND METHOD: In this case-control study, serum concentrations of iron, selenium, zinc, copper, and calcium were measured in 40 patients with HNSCC and compared to those of 37 healthy subjects. Statistical analysis was conducted using the Mann-Whitney test, Chi-square test, and independent t-test.

RESULTS: The mean ages of the case and control groups were 62.80±13.029 and 57.92± 9.367, respectively, with 45% of HNSCC patients and 59.5% of control subjects being male (p= 0.205). Serum concentrations of calcium and copper were higher, and those of selenium, zinc, and iron lower in the case group than in the control group. Adjusted logistic regression showed only copper, calcium, and iron concentrations to be significantly different between the two groups (p= 0.003, p= 0.018, and p= 0.047, respectively).

CONCLUSION: The case group had lower levels of iron, zinc, and selenium, and higher levels of calcium and copper than the control group. Evaluating serum concentrations of these trace metals could be useful for further screening of individuals at high risk.
