BackgroundLimited-stage small cell lung cancer (LS-SCLC) has a poor prognosis despite being potentially curable with standard concurrent chemoradiotherapy. The success of immune checkpoint inhibitors (ICIs) in extensive-stage SCLC has prompted investigation into combining immunotherapy with radiotherapy for LS-SCLC. This systematic review and single-arm meta-analysis aims to synthesize the evidence on this combined modality, providing pooled estimates of efficacy and safety to inform clinical practice and future trials.
MethodsFollowing PRISMA guidelines, we systematically searched PubMed, Embase, Cochrane Library, and Web of Science through July 2025 for studies evaluating radiotherapy combined with immunotherapy in patients with LS-SCLC. The primary outcomes analyzed included pooled objective response rate (ORR), median progression-free survival (mPFS), and median overall survival (mOS).
ResultsSix studies, encompassing 487 patients, met the inclusion criteria. The pooled analysis demonstrated an ORR of 57.7% (95% CI: 24.9–90.5%), a weighted mPFS of 13.6 months (95% CI: 11.3–15.9 months), and a pooled mOS of 33.7 months (95% CI: 26.7–40.7 months). Grade 3−4 treatment-related adverse events occurred in 42.2% of patients. Subgroup analyses revealed that a concurrent treatment sequence yielded a significantly higher ORR compared to sequential approaches (77.6% vs. 65.2% for immunotherapy followed by radiation vs. 25.8% for radiation followed by immunotherapy). Radiation dose was also identified as a critical determinant of efficacy. Anti-PD-L1 agents showed a numerically higher ORR than anti-PD-1 agents (96.0% vs. 65.0%).
ConclusionThe combination of radiotherapy and immunotherapy is a promising therapeutic strategy for LS-SCLC, demonstrating encouraging efficacy outcomes that appear favorable compared to historical benchmarks for chemoradiotherapy alone. Optimizing treatment sequencing, particularly favoring a concurrent approach, is crucial for maximizing clinical benefit. These findings support further investigation in randomized controlled trials to confirm the value of this combined modality and to identify predictive biomarkers for patient selection.
To identify factors influencing hypoglycaemia in patients with type 2 diabetes mellitus (T2DM) undergoing colonoscopy and to construct a predictive model for assessing hypoglycaemia risk.
A retrospective cohort study.
We retrospectively collected data on 598 T2DM patients who underwent colonoscopy and randomised them into a developmental cohort and a validation cohort in a 7:3 ratio. We used multivariate logistic regression to develop a predictive model for hypoglycaemia during colonoscopy and identify independent predictors in pre- and post-colonoscopy hypoglycaemia groups.
We identified 112 of 598 (18.7%) T2DM patients who experienced hypoglycaemia during the peri-colonoscopy period: 43 pre-colonoscopy, 61 post-colonoscopy and 8 at both junctures. Ultimately, five predictors—insulin, SGLT2 inhibitors, fasting after colonoscopy, fasting C-peptide and estimated glomerular filtration rate (eGFR)—were integrated into the predictive model. The AUC for predicting hypoglycaemia was 0.78 (95% CI, 0.71–0.84) and 0.82 (95% CI, 0.74–0.90) in the development and validation cohort, respectively. Variables associated with pre-colonoscopy hypoglycaemia included SGLT2 inhibitors, fasting C-peptide and eGFR, whereas the post-colonoscopy hypoglycaemia group was associated with metformin, duration of diabetes, fasting C-peptide and fasting after the examination.
This study successfully developed and validated a predictive model for assessing hypoglycaemia risk in T2DM patients during peri-colonoscopy.
Early identification of patients at high risk for peri-colonoscopy hypoglycaemia allows nurses to implement personalised preventive strategies. The predictive model enables clinical nurses to deliver tailored interventions based on individual risk factors, potentially reducing hypoglycaemia-related complications and improving patient safety outcomes.
This study provides nurses with a validated risk prediction tool for identifying high-risk type 2 diabetes patients during colonoscopy, enabling targeted blood glucose monitoring protocols and preventive interventions in clinical practice.
This study follows the STROBE guidelines for reporting cohort studies.
Diabetes patients contributed electronic health record datasets.
In recent years, the critical role of health literacy in diabetes management has become increasingly prominent. The aim of this study was to investigate the impact of social support on health literacy among patients with diabetes, to test the mediating role of self-efficacy and empowerment between social support and health literacy, and the moderating role of eHealth literacy.
A cross-sectional study conducted between August 2023 and June 2024.
This study adopted the cluster sampling method and conducted a questionnaire survey among 251 patients with diabetes in a tertiary hospital in Wuhu City, Anhui Province. The questionnaires included the Social Support Rating Scale, the Self-Efficacy for Diabetes scale, the Health Empowerment Scale, the eHealth Literacy Scale and the Diabetes Health Literacy Scale.
Social support was positively associated with health literacy in patients with diabetes. Self-efficacy and empowerment mediated the relationship and formed chained mediation pathways respectively. eHealth literacy has a moderating role between self-efficacy and empowerment.
The results revealed that social support influences health literacy among patients with diabetes through the mediating pathways of self-efficacy and empowerment, and that this process is moderated by eHealth literacy. These findings provide a theoretical basis and practical insights for improving health literacy among patients with diabetes.
Enhancing health literacy among people with diabetes by strengthening social support, self-efficacy and empowerment levels, while focusing on the technology-enabling role of eHealth literacy in this context.

This study aimed to identify the heterogeneous trajectories of frailty and determine the predictors of distinct trajectories in patients with heart failure.
A longitudinal study.
A total of 253 patients with heart failure were recruited at the cardiology department of a tertiary hospital between February and December 2023. Frailty was assessed at baseline, 1 and 4 months after discharge. Patients' sociodemographic characteristics, physical symptoms, nutritional status, psychological distress, illness perception and social networks were obtained at baseline using a structured questionnaire. Group-based trajectory modelling was performed to identify the heterogeneity of the trajectories of frailty. Multiple logistic regression and decision tree models were used to explore the predictors of heterogeneous trajectories of frailty.
Three distinct trajectories of frailty were identified in patients with heart failure: low frailty with high-degree improvement group (46.2%), moderate frailty with high-degree improvement group (41.1%) and high frailty with low-degree improvement group (12.6%). Multiple logistic regression analysis showed that physical symptoms, nutritional status, illness perception and employment status were entered as independent predictors of heterogeneous trajectories of frailty. The decision tree model demonstrated that physical symptoms were the primary predictors, followed by nutritional status, illness perception and psychological distress.
Three distinct categories of frailty trajectories were identified in patients with heart failure. Physical symptoms, nutritional status, psychological distress, illness perception and employment status were independent predictors of heterogeneous trajectories of frailty, with physical symptoms being the most important predictor.
Dynamic frailty assessment is recommended. Interventions aimed at alleviating physical symptoms, psychological distress and negative illness perception, and improving nutritional status may be conducive to delaying or reversing frailty in patients with heart failure, particularly in unemployed individuals.

The aim of this study was to investigate self-care behaviours of patients with chronic obstructive pulmonary disease (COPD), understand their complex interconnections and identify key behaviours influencing self-care and self-efficacy.
An observational, cross-sectional study design.
The outpatient department of two tertiary hospital.
A convenience sample of patients with a diagnosis of COPD were included (n = 222). Self-care behaviours were assessed using the Chinese version of self-care of chronic obstructive pulmonary disease inventory based on the Middle-Range Theory of Self-Care of Chronic Illness. Patient self-care efficacy was evaluated using Chinese version of Self-Care Self-Efficacy Scale in Chronic Obstructive Pulmonary Disease. Employing network analysis, associations between behaviours (nodes) and their interrelationships (edges) were deciphered. The study was reported following the STROBE checklist.
Among the spectrum of self-care behaviours, patients exhibited the most pronounced deficiencies in behaviours directed to enhancing breathing, monitoring extra-respiratory symptoms and problem-solving. Within the network, the most central emerging behaviour was the modification of prescribed therapy at the worsening of symptoms, as suggested by healthcare providers, which drives all self-care behaviours. The confidence in being able to do something to relieve symptoms, despite difficulties, was a bridging activator of self-care. The network structure underscored the prominence of self-care self-efficacy in driving self-care maintenance, monitoring, and management behaviours.
Education programs for COPD should prioritise enhancing breathing, symptom monitoring and problem-solving skills. The crucial self-care behaviour in COPD involves adjusting treatments in response to symptom changes. Patient confidence in symptom alleviation acts as a catalyst for self-care engagement. Targeted assessments addressing these aspects could enhance educational interventions, ultimately improving COPD patient outcomes.

To assess the effectiveness of different nonpharmacological treatments for severe radiation-induced oral mucositis in patients with head and neck cancer.
Radiation-induced oral mucositis is highly prevalent in patients with head and neck cancer. Current medications for radiation-induced oral mucositis are limited in effectiveness and susceptible to side effects, and while there is an increasing adoption of nonpharmacological interventions, the optimal one remains unclear.
Systematic review and network meta-analysis based on the PRISMA-NMA guidelines.
Six databases were searched. Two authors independently performed the literature screening, data extraction and methodological quality assessment of the included studies. Traditional pairwise meta-analysis was performed by R Studio. A network meta-analysis was then conducted to assess the effects of nonpharmacological interventions for severe radiation-induced oral mucositis in patients with head and neck cancer.
Fifty-two studies involving seven types of nonpharmacological interventions were enrolled. The network meta-analysis indicated that natural plant-based therapies might be the most effective, health education interventions might be the second most effective, and honey might be the third most effective interventions for reducing the incidence of severe radiation-induced oral mucositis. For reducing the incidence of severe oral mucositis-related pain, the pairwise meta-analysis showed that only natural plant-based therapies and health education interventions were effective.
Nonpharmacological interventions are effective in the management of severe radiation-induced oral mucositis among patients with head and neck cancer.
Nonpharmacological interventions are a category of safe and effective adjunctive therapies that should be encouraged in clinical practice.

To examine the multidimensional properties of caregiver burden among family caregivers of patients with advanced cancer in a palliative context.
A sequential, explanatory, mixed-method study was performed.
Family caregivers of patients diagnosed with advanced cancer were recruited from a palliative care department of a third-level hospital in Sichuan Province, China. The Caregiver Burden Inventory, Social Support Rating Scale and Connor–Davidson Resilience Scale were used to collect quantitative data, and a total of 150 caregivers were recruited from January 2022 to September 2022. Qualitative data were collected through semi-structured interviews, and a total of 22 caregivers were interviewed from October 2022 to November 2022. Survey data were analysed using descriptive statistics, and the factors of caregiver burden were identified using the Mann–Whitney U test, Kruskal–Wallis H test and Spearman correlations. Interpretative phenomenological analysis was performed to analyse the interview data to initially explore the multidimensions of caregiver burden. The following-a-thread method and convergence coding matrix were used for triangulation to examine the multidimensional properties of caregiver burden.
The participants experienced a moderate level of caregiver burden (32.97 ± 13.09). Through triangulation, six meta-themes and nine meta-subthemes were identified as multidimensional properties of caregiver burden, including physical (too many caring tasks and poor health condition), emotional (strong negative emotions resulting from patients' suffering and insufficient and ineffective family communication), social (less social interaction and social role conflict) and economic burdens, factors that aggravate burden (prevention and control of COVID-19 and spousal relationship with patients) and factors that mitigate burden (social support).
Multiple dimensions of caregiver burden were experienced by family caregivers of patients with advanced cancer in the palliative context. Family-centred palliative care must be further developed.
It is important to develop family-centred palliative care. Therefore, the focus must be on developing a rational understanding of palliative care in public and a culture-oriented death education in palliative units.
This study adopted a mixed-method approach to comprehensively understand the phenomenon of and factors in caregiver burden in the Chinese palliative oncology context. Our findings suggest that family caregivers in palliative oncology experience a moderate level of caregiver burden, with dimensions including physical, emotional, social and economic burdens, among which emotional burden is the most prominent. The findings of this study provide policy makers and nurse practitioners with targets to be addressed in family-centred care in Chinese palliative units.
The results of this study are reported based on the guidelines of the Mixed-Methods Article Reporting Standards.
Eligible caregivers were invited to participate in the study and semi-structured interviews. Nurse managers of the palliative unit helped us access the patient-management system.
