A Late Pleistocene archaic human tooth from Gua Dagang (Trader’s Cave), Niah national park, Sarawak (Malaysia)

by Darren Curnoe, Mohammed S. Sauffi, Hsiao Mei Goh, Xue-feng Sun, Roshan Peiris

The rarity of Late Pleistocene hominin remains from Insular Southeast Asia (ISEA) has hampered our ability to understand a crucial episode of human evolutionary history, namely, the global dispersal of Homo sapiens from Africa. Moreover, recent discoveries indicate a surprising level of taxic diversity during this time with at least two species—H. floresiensis and H. luzonensis—endemic to the region when H. sapiens first arrived. A third hominin dubbed the ‘Denisovans’ is shown from DNA evidence to have interbred with the ancestors of contemporary Indigenous populations across ISEA, New Guinea and Australia. Yet, the Denisovans have not been identified from the fossil record of the area despite recent breakthroughs in this regard on mainland East Asia. New excavations by our team at the Trader’s Cave in the Niah National Park (‘Niah Caves’), northern Borneo, have yielded an isolated hominin upper central permanent incisor dated with Optically Stimulated Luminescence dating of sediments to about 52 − 55 thousand years ago. Specimen SMD-TC-AA210 has a massive crown absolutely and relative to its root size, the crown is wide (mesiodistally) and relatively short (labiolingually). Morphologically, it exhibits a very strong degree of labial convexity, pronounced shovelling, and the bulging basal eminence exhibits several upward finger-like projections. Labial enamel wrinking on the enamel-dentine junction is expressed as two large ridges exhibiting numerous spine-like projections, and the lingual extensions on the enamel surface of the basal eminence are expressed as six extensions. This combination of crown size and morphological traits is not normally found in H. sapiens and instead characterises archaic members of Homo such as H. erectus, H. neanderthalensis and Middle Pleistocene hominins sharing a clade with H. heidelbergensis. The Trader’s Cave tooth suggests that an archaic hominin population inhabited northern Borneo just prior to or coincident with the arrival of H. sapiens as documented at the nearby West Mouth of the Niah Great Cave.

Exosomes from bone marrow mesenchymal stem cells protect melanocytes under vitiligo-related conditions through induction of NRF2/HO1 expression

by Xuecheng Sun, Bo Huang, Gaobo Ruan, Aie Xu

Background

Vitiligo, a chronic autoimmune disease linked to excess oxidative stress, can be temporarily improved. Bone marrow mesenchymal stem cells (BMSCs)-derived exosomes (BMSCs-Exos) have recently emerged as a promising novel therapeutic means for vitiligo.

Methods

Exosomes were isolated and characterized from BMSCs-conditioned medium. PIG3V cells and those transfected with NRF2 siRNA or negative control were cultured under normal conditions or exposure to hydrogen peroxide (H₂O₂) to induce oxidative stress, with addition of BMSCs-conditioned medium, conditioned medium from BMSCs pretreated with GW4869 (referred to as BMSCs-GW4869), or BMSCs-Exos. Cell viability, apoptosis, and oxidative stress parameters, including cellular glutathione (GSH)/oxidized glutathione (GSSG) ratio, superoxide dismutase (SOD), reactive oxygen species (ROS), and malondialdehyde (MDA), were assessed. The expression of Ki67, NRF2, HO1, BAC, and Bcl-2 was measured.

Results

BMSC-Exos significantly enhanced cell viability and reduced apoptosis and oxidative stress in H₂O₂-treated PIG3V cells. Simultaneously, BMSCs-Exos reversed H₂O₂-induced downregulation of Ki67, NRF2, HO1, and Bcl-2, and upregulation of BAX in PIG3V cells. Silencing NRF2 by siRNA in PIG3V cells prior to H2O2 treatment abolished the protective effect of BMSCs-Exos and decreased the HO1 expression.

Conclusions

BMSCs-Exos protect melanocytes from vitiliog-related oxidative stress by mitigating oxidative damage through induction of NRF2/HO1 expression.

Development and Preliminary Application of a KAP Scale for Nursing Assistants in Pain Care for Older Adults With Dementia

ABSTRACT

Aim

This study aimed to develop and preliminarily validate the KAP scale for pain management in older adults with dementia among nursing assistants.

Design

A cross-sectional study.

Methods

An initial item pool was constructed through literature reviews, semi-structured interviews and team discussions. Items were screened and optimised through two rounds of Delphi expert consultations, a pilot survey and item analysis, yielding a draft version of the scale. Psychometric evaluation was conducted to refine the scale into its final form.

Results

The final KAP scale developed in this study comprised 31 items. The scale exhibited good content validity, with item-level content validity index (I-CVI) values ranging from 0.83 to 1.00. Exploratory factor analysis revealed that the scale extracted five factors, which accounted for 65.732% of the cumulative variance, and all items demonstrated rotated factor loadings > 0.5, indicating good construct validity. The Cronbach's α coefficients for the knowledge, attitudes and practices dimensions were 0.877, 0.915 and 0.935, respectively, and the split-half reliability coefficients were 0.909, 0.886 and 0.864.

Conclusion

The KAP scale for pain care in older adults with dementia developed in this study possesses good reliability and validity and can be used to assess the knowledge, attitudes and behavioural levels of nursing assistants in pain care.

Implications for the Profession and/or Patient Care

This study developed and psychometrically validated a KAP scale specifically designed to assess pain care for older adults with dementia among nursing assistants. Clinical managers can utilise this tool to systematically identify deficiencies in staff members' knowledge, attitudes or practices, thereby providing scientific evidence for the development of targeted pain care training programs and pain management strategies. This contributes to enhancing nursing assistants' pain care competence, ultimately alleviating the pain burden of older adults with dementia and improving their quality of life.

Reporting Method

The STROBE checklist was used as a guideline.

Global trends in Alzheimer’s disease and other dementias: A comprehensive analysis of incidence, socio-demographic variations, and future projections

by Ruixue Qin, Huijuan Zhao, Hui Gao, He Liu

Background

Alzheimer’s disease and other dementias (ADRD) are significant global health concerns, with rising incidence rates and substantial social and economic implications due to population aging.

Methods

We investigated trends in ADRD incidence from 1992 to 2021 across age, sex, and socio-demographic index (SDI) regions, utilizing data from the Global Burden of Disease (GBD) 2021 platform. An age-period-cohort (APC) model was employed to analyze the effects of age, period, and birth cohort on ADRD incidence, and a Bayesian age-period-cohort (BAPC) model was used to predict future trends.

Results

Globally, the age-standardized incidence rates (ASIR) remained relatively steady. However, the total number of ADRD cases witnessed a remarkable 141.25% increase, with 9,837,056 cases (95% UI: 8,620,519–11,163,700) in 2021. High SDI regions exhibited higher ASIR, whereas high-middle SDI regions showed the greatest growth, particularly among females. The net drift of ADRD incidence ranged from 0.43% per year in China to −0.68% per year in Denmark. Age effect was consistent across SDI regions, increasing exponentially with age. The 60–64 age group experienced the fastest annual incidence growth. High-middle SDI regions faced unfavorable period and cohort effects.

Conclusion

Although progress in ADRD globally, significant regional and sex disparities persist. Strengthened surveillance and management of adults over 60 are urgently needed. Targeted public health policies and interventions are essential to address the escalating global dementia burden.

Dysregulated serum chloride and clinical outcomes in critically ill adults: A systematic review and meta-analysis

by Xiaoliang Wan, Feiyao Deng, Xue Bai, Chenxi Xiang, Chuan Xu, Linxiao Qiu

Dysregulated serum chloride levels are prevalent in critically ill patients. However, their clinical impact remains unclear. This first systematic review and meta-analysis quantified the prevalence of hypochloremia and hyperchloremia, and their associations with mortality and acute kidney injury (AKI) in critically ill populations. We searched PubMed, Embase, Web of Science, and the Cochrane Library for studies reporting hyperchloremia prevalence or outcomes in adult ICU patients until August 2025. Statistical analyses were conducted using Stata v16.0, and study quality was assessed using the Newcastle-Ottawa Scale. 34 studies (n = 175,021 patients) were included. The aggregated prevalence of hyperchloremia was 34% (95% CI [26%−43%]) and hypochloremia was 14% (95% CI [1%−28%]). Meta-analysis demonstrated that both hyperchloremia and hypochloremia were significantly associated with increased mortality, conferring a 28% (OR = 1.28, 95% CI [1.08–1.52]) and 55% (OR = 1.55%, 95% CI [1.33–1.81]) elevated risk for mortality, respectively. Crucially, a dose-response analysis revealed a non-linear relationship between serum chloride levels and mortality, confirming that the risk is independently elevated at both extremes. Furthermore, hyperchloremia was linked to an increased risk of AKI (OR = 1.40, 95% CI [1.07–1.85]). These findings establish dysregulated serum chloride as a common and clinically significant biomarker, underscoring the necessity of monitoring and managing both high and low chloride levels in critically ill patients. Future large-scale studies are warranted to validate these results and elucidate the mechanistic pathways linking chloride dysregulation to such adverse outcomes.

Effects of peer-led or peer-supported physical activity interventions on health outcomes in community-dwelling older adults: a protocol for a systematic review and meta-analysis of randomised controlled trials

Por: Xue · D. · Peng · J. · Wei · L. · Cui · C. · Ye · Y. · Wang · Y.
Introduction

Physical activity (PA) has considerable benefits for older adults, yet they often face various barriers that hinder participation. Peer-led or peer-supported PA interventions represent a promising strategy to address barriers, such as cost and lack of motivation. Although existing reviews suggest that these interventions improve PA adherence, combining randomised controlled trials (RCTs) with other study designs may weaken their validity. Furthermore, their effects on PA levels and physical function are inconsistent, and their impacts on cognitive abilities, psychosocial well-being and social support, as well as the influence of peer characteristics and programme design, remain unexamined. This review aims to synthesise evidence regarding the effectiveness of peer-led or peer-supported PA interventions across multiple health outcomes and identify possible influencing factors.

Methods and analysis

The search will encompass six English and three Chinese databases, namely, PubMed, Web of Science, Embase, Cumulative Index to Nursing and Allied Literature, PsycINFO, CENTRAL, China National Knowledge Infrastructure, Wanfang Data and the Chinese Biomedical Literature Database. It will cover literature from inception to December 2025. Trial registries will be searched, and a manual search of relevant studies will also be conducted. RCTs that focus on community-dwelling older adults participating in peer-led or peer-supported PA interventions will be included. Outcomes include PA levels, physical function, cognitive function, psychosocial well-being, self-efficacy, social support, health-related quality of life (HRQoL) and programme adherence. Two reviewers will independently screen the literature, extract data and evaluate the risk of bias by using the Cochrane Risk of Bias Tool 2.0. Meta-analyses will be conducted for outcomes reported in at least two studies, and narrative analyses will be performed for others. Subgroup analyses, metaregression, sensitivity analyses and assessments of publication bias will be conducted as appropriate. The Grading of Recommendations, Assessment, Development and Evaluations approach will be used to assess the certainty of evidence.

Ethics and dissemination

Ethical approval is not required because only published data will be used. Results will be disseminated through peer-reviewed publications and conference presentations.

TNFAIP3 alleviates cerebral ischemia-reperfusion injury by inhibiting M1 microglia polarization via deubiquitination of RACK1

by Wenya Bai, Shixuan Liu, Guilin Zhou, Xuelian Li, Huan Jiang, Jianlin Shao, Junchao Zhu

Background

Microglia polarization plays a crucial role in the progression of cerebral ischemia-reperfusion injury (CIRI), but the mechanisms remain largely undefined. The preset study aimed to investigate the mechanism of microglia polarization following CIRI.

Methods

CIRI was modeled in C57BL/6J mice through middle cerebral artery occlusion-reperfusion and in BV2 cells via oxygen and glucose deprivation/reoxygenation. Reverse transcription-quantitative PCR, western blotting, flow cytometry and fluorescence staining were used to detect the expression levels of key proteins associated with microglia polarization, as well as the expression of TNFAIP3 and RACK1. The interaction between TNFAIP3 and RACK1 was verified by co-immunoprecipitation. TNFAIP3 or RACK1 gene interference (overexpression and/or silencing) was employed to examine the role of the TNFAIP3/RACK1 axis in microglia polarization following CIRI.

Results

The results revealed that Arg-1 expression decreased, inducible nitric oxide synthase expression increased and TNFAIP3 was upregulated 24 h after CIRI. Furthermore, TNFAIP3 interacted with RACK1 to deubiquitinate and increase the expression of RACK1. These results indicate that knocking down either TNFAIP3 or RACK1 promotes microglia M1 polarization, and overexpression of RACK1 can promote microglia M2 polarization. RACK1 exerts its neuroprotective effects through NF-κB, as demonstrated by the use of NF-κB inhibitors.

Conclusion

The present findings indicate that TNFAIP3 inhibits M1 microglial polarization via deubiquitination of RACK1 after CIRI, RACK1 exerts its effects through NF-κB.

Identification of pathogenic variants for the development of ultra-long axial length in myopic children

by YanYing Zhu, XueYan Li, YueXin Chen, HaiYan Xie, YuKun Liu, XiaoChen Xu, Jing Wang

Purpose

Axial elongation is a key factor in myopia progression, yet its genetic basis remains incompletely understood. This study aims to identify pathogenic genetic variants associated with excessively elongated axial length in children.

Methods

This study included 56 children with axial lengths exceeding the normal range for their age group, and whole-exome sequencing (WES) was performed on their oral mucosal samples. Clinical evaluations included axial length measurement, refraction testing, and fundus photography to assess the degree of myopia and retinal changes. Co-segregation analysis was conducted in selected families (F#1, F#2, F#5) to validate the familial inheritance patterns of the variants.

Results

Fifteen children carried variants in genes including BBS2, OPN1LW, P4HA2, FBN1, LOXL3, FZD4, USH2A, COL2A1, and BFSP2, with five novel variants identified: BBS2 (c.700C > T), P4HA2 (c.1382C > G), FBN1 (c.7130T > C), LOXL3 (c.1580delC), and FZD4 (c.1315G > A). Notably, a rare compound heterozygous BBS2 variant (c.700C > T/c.534 + 1G > T) was found in a non-syndromic child, and the P4HA2 (c.419A > G) variant in family F#5 exhibited a phenotype distinct from previous studies.

Conclusions

This study identified five novel variants sites and discovered two cases with phenotypes distinct from previous studies, thereby expanding the genetic variant spectrum associated with myopia and providing new targets for genetic screening and intervention.

Por: Cai · H. · Xu · D. · Wang · Z. · Huang · B. · Xue · X. · Bai · H. · Man · Y. · Lei · D. · Wu · Q. · Ni · Y. · Lei · J. · Shi · J.
Introduction

EmbryoGlue, a commercially available hyaluronic acid (HA)-enhanced culture medium, is commonly recommended as an adjunct to support embryo implantation. Given the current lack of conclusive evidence regarding its efficacy and safety, this study aims to evaluate the effectiveness and safety of HA-enriched medium in women undergoing in vitro fertilisation (IVF) treatment.

Methods and analysis

This multicentre, patient-blinded, randomised controlled trial involves couples planning a single fresh or frozen blastocyst-stage embryo transfer. On the morning of embryo transfer, individual blastocysts are randomly allocated to either a high-concentration HA medium (EmbryoGlue, 0.5 mg/mL) or a conventional low-concentration HA medium (G-2 PLUS, 0.125 mg/mL). The primary outcome is live birth rate per embryo transfer, with secondary outcomes including biochemical pregnancy rate, clinical pregnancy rate, miscarriage rate, ectopic pregnancy rate, ongoing pregnancy rate, multiple pregnancy rate, as well as obstetric and perinatal outcomes and related complications. The trial plans to enrol 858 female patients from four IVF centres in China, with 429 patients in each group.

Ethics and dissemination

The study has been approved by the Ethics Committee of Northwest Women’s and Children’s Hospital (approval no.: 2024–127), and all participating centres have obtained approvals from their respective institutional review boards or ethics committees. Results will be disseminated through publication in a peer-reviewed open-access journal and oral presentations at relevant domestic and international academic conferences.

Factors Associated With Decision‐Making Self‐Efficacy Among Family Members of ICU Patients: A Cross‐Sectional Study

ABSTRACT

Aims

To describe the level of family decision-making self-efficacy and its associated factors among Chinese family members of ICU patients.

Design

Cross-sectional descriptive quantitative study.

Methods

Using convenience sampling, 154 ICU patients and their family members from two tertiary hospitals completed a paper-based questionnaire assessing sociodemographic characteristics of patients and their family members, patients' disclosure of preferences to their family members, and family members' decision-making self-efficacy, anxiety and depression, uncertainty of illness, coping and social support. The data were analysed using independent-samples t-tests, one-way analysis of variance, Pearson correlation and multiple linear regression.

Results

The average scores of self-efficacy in treatment, comfort promotion and facing death decision-making were 4.3 (SD = 0.6; range = 1–5), 4.2 (SD = 0.6; range = 1–5) and 3.5 (SD = 0.6; range = 1–5), respectively. Active coping was a predictor of self-efficacy in treatment, comfort-promoting and facing death decision-making. Patients' disclosure of preferences regarding mechanical ventilation, family members' anxiety and illness uncertainty were predictors of self-efficacy in treatment decision-making. Patients' disclosure of preferences regarding expensive medications was a predictor of self-efficacy in comfort-promoting decision-making, and patients' age was a predictor of self-efficacy in facing death decision-making.

Conclusions

Chinese family members of ICU patients reported relatively high self-efficacy in treatment and comfort promotion decision-making but lower self-efficacy in facing death decision-making. Active coping plays a critical role in enhancing decision-making self-efficacy across these three types of decisions. The predictors of decision-making self-efficacy varied according to the specific type of decision.

Implications for the Profession and/or Patient Care

For Chinese family members of ICU patients, targeted strategies to strengthen their active coping skills are key to enhancing their confidence in making decisions with or for patients. Patients' disclosure of preferences to their family members is helpful for improving family members' confidence in making treatment and comfort promotion decisions. Extra support is especially needed for end-of-life decision-making, particularly when the patient is younger.

Impact

This research informs future interventions by highlighting active coping and patients' disclosure of preferences to family members as key factors to strengthen decision-making self-efficacy among Chinese family members of ICU patients. However, family members' decision-making self-efficacy appears to be culturally specific, underscoring the need to design family-centered critical care approaches that are tailored to cultural contexts in other settings. Besides, while our research found a positive association between anxiety and self-efficacy in treatment decision-making, the relationship between them requires further investigation.

Effects of Non‐Pharmacological Interventions on Psychological Distress in Patients With Malignant Tumors: A Systematic Review and Network Meta‐Analysis

ABSTRACT

Background

The incidence of psychological distress in patients with malignant tumors is high, which seriously affects the treatment compliance and quality of life of patients and even reduces the survival time. Non-pharmacological interventions are acceptable to patients because of their minor side effects. However, among the numerous interventions, which non-pharmacological intervention has demonstrated the most significant effect is still unclear.

Aims

This study aimed to compare the efficacy of different non-pharmacological interventions on psychological distress in patients with malignant tumors.

Methods

The databases, including Wanfang databases, Chinese National Knowledge Infrastructure, China Science and Technology Journal Database, SinoMed, PubMed, Embase, Web of Science, Cochrane Library, and PsycINFO, were searched systematically for randomized controlled trials on non-pharmacological interventions for psychological distress in patients with malignant tumors that were published up to July 5, 2025. Revman 5.3 and Stata 18.0 were used for paired and network meta-analysis, respectively.

Results

A total of 43 randomized controlled trials were included. The area under the cumulative sorting curve was ranked as Naikan Morita therapy (99.6%) > acceptance and commitment therapy (79.0%) > music therapy (78.3%) > logotherapy (77.8%) > behavioral activation (67.5%) > solution-focused nursing (66.1%) > dignity therapy (51.2%) > mindfulness-based stress reduction (50.6%) > mindfulness-based cognitive therapy (46.7%) > Mika app (39.8%) > psychological education (38.5%) > multi-dimensional collaborative nursing (29.0%) > life review therapy (26.0%) > exercise therapy (14.7%) > usual care (5.0%).

Linking Evidence Action

Non-pharmacological interventions had overall benefits in reducing the psychological distress of patients with malignant tumors, especially Naikan Morita therapy, acceptance and commitment therapy, music therapy and logotherapy. However, more high-quality randomized controlled trials are still needed to obtain more reliable conclusions.

The Relationship Between Occupational Stressors and Resilience Among Emergency Department Nurses: A Multicenter Cross‐Sectional Network Analysis

ABSTRACT

Background

The global nursing shortage poses a critical challenge to healthcare systems. Emergency department (ED) nurses face high occupational stress due to demanding environments and strained patient-family interactions. Chronic stress impairs resilience and health, contributing to burnout and attrition. Understanding ED nurses' stressors and resilience is vital for workforce stability.

Aims

To identify core elements and interrelationships of occupational stressors and resilience among ED nurses in Zhejiang Province, China, using network analysis, and to explore intervention strategies.

Design

Cross-sectional study.

Methods

From November 2024 to January 2025, data were collected from 990 ED nurses in 26 hospitals across 11 cities. Measures included a demographic questionnaire, the Chinese version of the Stressor Scale of Emergency Nurses, and the Resilience Structure Scale for Healthcare Professionals. Network analysis was conducted to illustrate the interconnections between stressors and resilience factors, while accounting for significant sociodemographic covariates.

Results

A total of 990 nurses participated in the study. Violence-related stressors, such as physical assault and witnessing aggression, were the most prominent nodes in the stressor network. Key resilience elements included reframing patient or family criticism positively and timely emotional regulation. Bridge analysis highlighted ‘viewing criticism as encouragement’ as a crucial link connecting stress and resilience.

Conclusion

ED nurses work under intense stress from violence and scrutiny, which undermines resilience. Strengthening key resilience factors—especially cognitive reframing and emotional regulation—may buffer stress and enhance coping. Bridge nodes offer targeted points for intervention.

Patient or Public Contribution

None.

Impact

This study clarifies the network of occupational stressors and resilience in ED nurses, identifying key intervention targets. It supports interventions focusing on cognitive adjustment, emotional regulation and interpersonal support to build resilience and reduce stress.

Curcumin attenuates LPS-induced inflammation in RAW 264.7 cells: A multifaceted study integrating network pharmacology, molecular docking, molecular dynamics simulation, and experimental validation

by Xiaojing Gong, Dingshan Xue, Hongyan Meng, Bing Xie, Lihua Zhao, Chuanhui Zang, Jingjing Kong

Background

Inflammation is a critical immune response that protects the body from infections and injuries. However, chronic inflammation can lead to diseases such as cancer. Curcumin, a bioactive compound extracted from Curcuma longa, has been widely studied for its anti-inflammatory properties. Despite extensive research, the comprehensive molecular mechanisms underlying curcumin’s anti-inflammatory effects, particularly its multi-target regulatory network, remain incompletely understood. This study aims to elucidate these mechanisms using an integrated approach combining network pharmacology, molecular docking, molecular dynamics simulation, and in vitro experimental validation.

Methods

We utilized network pharmacology to identify potential targets and pathways involved in curcumin’s anti-inflammatory effects. Molecular docking and dynamics simulation were conducted to evaluate the binding affinity and stability of curcumin with key inflammatory targets. The anti-inflammatory effects of curcumin were further validated in vitro using LPS-induced RAW 264.7 cells. Cell viability, NO content, and mRNA expression levels of pro-inflammatory cytokines (IL-1β, IL-6, and TNF) were assessed.

Results

Network pharmacology identified 135 potential targets for curcumin’s anti-inflammatory effects, with key pathways including TNF, HIF-1, PI3K-Akt, JAK-STAT, and MAPK signaling pathways. Molecular docking revealed strong binding affinities of curcumin with core targets such as IL-6, TNF, IL-1β, AKT1, and STAT3, with binding energies ranging from −6.2 to −7.5 kcal/mol. Molecular dynamics simulations demonstrated the stability of these complexes over a 100-nanosecond period. In vitro experiments showed that curcumin significantly reduced NO production and mRNA expression of IL-1β, IL-6, and TNF in LPS-induced RAW 264.7 cells, with optimal effects observed at a concentration of 125 μg/mL.

Conclusion

Our study provides a comprehensive understanding of curcumin’s anti-inflammatory mechanisms through an integrated approach. The findings highlight curcumin’s potential as a therapeutic agent for inflammatory diseases. However, further in vivo studies are necessary to fully elucidate its therapeutic efficacy and mechanisms of action.

Curated mitochondrial genome reference database of state key protected wild mammal in China

by Xia Huang, Guihua Zhang, Joseph D. Orkin, Shiyun Liu, Shan Jiang, Yinhui Zhao, Pengfei Fan, Lianghua Huang, Xiaoming Zhang, Xueyou Li, Song Li, Kai He

Effective conservation of wild mammals necessitates accurate taxonomic classification and reliable genetic reference data. In China, the List of State Key Protected Wild Animals serves as a critical tool for species protection. However, taxonomic revisions and gaps in genetic data can impede its effectiveness. In this study, we updated the List of State Key Protected Wild Animals (2021) by incorporating recent taxonomic and distributional evidence, resulting in a refined list of 169 mammalian species that are protected. We identified 15 taxa lacking complete mitochondrial genome data and addressed this gap by generating 12 new mitogenomes for nine taxa using a combination of GenBank database mining and next-generation sequencing of museum specimens and fecal samples. These efforts led to the establishment of a curated mitochondrial genome reference database encompassing 164 species. Our analyses also uncovered taxonomic ambiguities in genera such as Moschus and Naemorhedus, and highlighted mislabeling issues within public genetic databases. This curated database enhances the accuracy of forensic species identification, supports biodiversity monitoring, and strengthens wildlife law enforcement. Our findings underscore the value of integrating historical specimens with mitogenomic approaches to advance wildlife conservation efforts.

Death Anxiety Among Patients With Advanced Cancer: A Systematic Review and Meta‐Analysis

ABSTRACT

Aims

To identify and synthesise the levels of death anxiety and potential moderating factors in patients with advanced cancer.

Design

A systematic review and meta-analysis of observational studies.

Data Sources

A comprehensive search was conducted across 10 electronic databases, including PubMed, Cochrane, Embase, Web of Science, CINAHL, PsycINFO, Scopus, Chinese Biomedical, China National Knowledge Infrastructure, and WANFANG, covering publications in both English and Chinese from inception through June 18, 2025.

Review Methods

Two independent reviewers performed study selection, data extraction, and quality assessment. Meta-analyses were conducted using STATA 16 software. Predefined subgroup analyses and meta-regression were carried out to examine variations in death anxiety among advanced cancer patients based on participant characteristics, disease-related factors, and study-level variables.

Results

Twenty-one studies involving 4337 patients with advanced cancer met the inclusion criteria. These studies, published between 1978 and 2025, were conducted across five countries. Meta-analyses were performed separately for 16 studies using the original 15-item dichotomous Templer Death Anxiety Scale and 3 studies using an adapted five-point Likert version. Both analyses indicated high levels of death anxiety among patients. Differences in participant age, country, continent, and publication year contributed to the variation in findings.

Conclusion

Advanced cancer patients experience high levels of death anxiety, with age, country, continent, and publication year identified as key moderating factors. Targeting these factors through tailored interventions, promoting a supportive culture around death, and providing effective psychological training for patients can help reduce anxiety. These efforts aim to equip patients to understand and cope with the realities of death, ultimately improving their psychological well-being.

Impact

This review highlights the high levels of death anxiety in advanced cancer patients and identifies potential moderators. It underscores the need for targeted interventions to improve psychological care, particularly in end-of-life settings.

Effectiveness, Process, and Economic Outcomes of Integrated Care for Community‐Dwelling Frail Older Adults: A Systematic Review and Meta‐Analysis

ABSTRACT

Aims

To assess the effectiveness, process, and economic outcomes of integrated care for community-dwelling frail older adults.

Design

A systematic review and meta-analysis.

Data Sources

We searched nine databases, including PubMed, Web of Science, CINAHL, Embase, the Cochrane Library, CNKI, SinoMed, Wanfang, and VIP, three trial registers, grey literature, and reference lists up to April 2024, with an updated search in March 2025.

Review Methods

Randomised controlled trials and non-randomised studies of interventions involving integrated care for community-dwelling frail older adults were included. Data analysis was conducted using the Comprehensive Meta-Analysis software.

Results

This review included 12 studies involving 6819 community-dwelling frail older adults from high-income regions. The results indicated that integrated care had significantly positive effects on frailty and functional ability, but not on social function, hospitalisation, nursing home admission, quality of life, and mortality. Outcomes of caregivers and professionals were rarely reported. The cost-effectiveness of integrated care has not been confirmed by limited evidence. Few studies have adopted a systematic approach to designing and conducting comprehensive process evaluations guided by scientific frameworks.

Conclusion

Integrated care improves frailty and functional ability in community-dwelling frail older adults but lacks consistent benefits for other outcomes. The lack of evidence on cost-effectiveness and the caregiver and professional outcomes highlight critical gaps in current research. The absence of systematic process evaluations underscores the need for future studies to adopt rigorous frameworks to assess them.

Impact

This implicates that more research, particularly in underserved regions that lack a high standard of usual medical services, should emphasise the outcomes of caregivers and healthcare professionals, process evaluation, and health economics. Policymakers and practitioners must consider these gaps when implementing integrated care programmes to ensure equitable and sustainable healthcare solutions.

Glasgow Coma Scale Practice Among Emergency Nurses in China: A Multicenter Cross‐Sectional Study

ABSTRACT

Aim

To analyse current Glasgow Coma Scale practice among emergency nurses in China and identify factors influencing assessment quality.

Design

A quantitative, multicenter cross-sectional design.

Methods

A convenience sample of 1740 emergency nurses from secondary and tertiary hospitals across 21 provinces completed a validated structured questionnaire between March and April 2025. Participants had at least 6 months of emergency nursing experience. Data analysis included descriptive statistics, chi-square tests, and multiple logistic regression to examine factors influencing correct Glasgow Coma Scale application.

Results

Participants had a mean age of 29.8 years (SD = 6.2). Only 52.5% of nurses demonstrated correct Glasgow Coma Scale application despite 97.0% having theoretical knowledge of scoring criteria. While 56.8% had received Glasgow Coma Scale training, significant standardisation deficiencies emerged. Notably, 41.8% of departments lacked operational guidelines, and 53.7% of nurses experienced scoring disagreements with colleagues. Clinical utilisation varied substantially by patient population: traumatic brain injury (97.8%), neurological diseases (96.9%), and systemic critical illness (85.8%). Multivariate analysis identified six significant factors influencing correct application: standardised training (OR = 2.252, 95% CI: 1.789–2.825), manageable workload ≤ 4 patients/shift (OR = 1.652, 95% CI: 1.327–2.057), departmental guidelines (OR = 1.523, 95% CI: 1.233–1.881), extensive work experience ≥ 9 years (OR = 1.534, 95% CI: 1.182–1.992), while multidisciplinary collaboration issues (OR = 0.559, 95% CI: 0.439–0.712) and special patient experience (OR = 0.520, 95% CI: 0.406–0.666) were associated with reduced accuracy.

Conclusion

Substantial standardisation challenges exist in Glasgow Coma Scale practice among Chinese emergency nurses, characterised by significant gaps between theoretical knowledge and clinical application. Major barriers include insufficient standardised guidelines, inconsistent training approaches, and inadequate interdisciplinary collaboration.

Impact

Healthcare administrators should develop national standardised guidelines, implement simulation-based training programs, optimise emergency workflows, and integrate alternative assessment tools to enhance consciousness assessment accuracy and improve patient safety.

Blood flow restriction training combined with muscle energy technology for upper limb functional recovery in poststroke spasticity: a randomised controlled trial protocol at a tertiary hospital in Jiaxing, China

Introduction

Stroke is a leading cause of death and disability worldwide, with spasticity affecting 4%–42.6% of stroke survivors. Prolonged spasticity can lead to pain, restricted joint mobility and muscle weakness. Current non-pharmacological treatments include physical therapy, orthoses and surgery. Muscle energy techniques (METs) and blood flow restriction training (BFRT) have shown promise in improving muscle function and reducing spasticity. This study aims to investigate the combined effect of MET and BFRT on upper limb motor function in patients with poststroke spasticity.

Methods and analysis

This study is a single-blind randomised controlled trial involving patients with poststroke spasticity. Participants will be randomly assigned to either the MET+BFRT group or the passive stretching group. Both groups will receive conventional rehabilitation therapy, with additional MET+BFRT or passive stretching interventions. The intervention will last for 6 weeks, with four sessions per week. Primary outcomes include the simplified Fugl-Meyer assessment (FMA) and surface electromyography, while secondary outcomes include the Modified Barthel Index and the Modified Ashworth Scale.

Based on literature data, patients who had a stroke have an average baseline upper limb FMA score of 40 points. Conventional rehabilitation typically improves FMA to 46 points (SD=8). This trial expects an additional 6-point improvement from the intervention. With α=0.05 (two-sided), 90% power (1–β=0.90) and 10% dropout rate, PASS V.11.0 calculation indicates a minimum requirement of 42 participants per group.

Statistical analysis will be conducted using IBM SPSS Statistics V.25. Intention-to-treat analysis will be used to analyse the result, which means the last observation will be used for interpolation when data are missing. Continuous variables will be summarised as mean±SD for normally distributed data or as median and IQRs for non-normally distributed data. Categorical variables will be presented as frequencies and percentages. For continuous variables that meet the criteria of normal distribution and homogeneity of variance, two-way analysis of variance with repeated measures will be applied; for those that do not meet these criteria, the Mann-Whitney U test will be used. Categorical variables will be analysed with the 2 test or Fisher’s exact test.

Ethics and dissemination

The study protocol has been approved by the ethics committee of Jiaxing Hospital of Traditional Chinese Medicine (2024-016). Participants will provide written informed consent before inclusion. The results will be disseminated through peer-reviewed journals and conference presentations.

Changed Personal Attitudes Predict Sexual Behaviours Among Men Living With HIV in the Era of U=U: A Half‐Longitudinal Study

ABSTRACT

Introduction

In the era of ‘Undetectable = Untransmittable’ (U=U), reductions in condom use and increases in casual partnerships may contribute to elevated risks of coinfection with other sexually transmitted infections (STIs) and HIV super-infections among men living with HIV. These trends may reflect a shift in personal attitudes towards sexual behaviour and HIV risk, yet their influence on actual behaviours remains unclear.

Aim

To investigate how changes in personal attitudes and safe sex self-efficacy influence sexual decision-making.

Design

Two-wave longitudinal study design.

Methods

We conducted a 3-month longitudinal study from March to December 2023 among HIV-positive men (≥ 18 years) initiating ART in Changsha, China. Cross-lagged panel analysis and half-longitudinal mediation analysis were used to examine how changes in personal attitudes influenced sexual behaviours.

Results

427 men living with HIV were included at baseline, and 301 completed the follow-up survey. Sexual behaviours were associated with personal attitudes, namely safe sex fatigue, viral load/transmission beliefs, and sexual sensation seeking. More positive personal attitudes in these domains at baseline predicted lower safe sex self-efficacy over 3 months, while reduced baseline self-efficacy increased the likelihood of engaging in condomless sex and/or multiple sexual partners. All three personal attitude domains had significant indirect effects on sexual behaviours via safe sex self-efficacy.

Conclusion

In the era of U=U, the changed personal attitudes among men living with HIV may lead to the increased likelihood of engaging in condomless sex and/or having multiple sexual partners, and safe sex self-efficacy serves as a mediator in this relationship.

Impact

This study highlights the potential influence of attitudinal changes on sexual behaviours among men living with HIV in the ‘U=U’ era. Findings provide valuable evidence for developing more targeted interventions that address not only behavioural outcomes but also underlying personal attitudes.
