To compare use of electronic nicotine delivery systems (ENDS) with nicotine replacement therapies (NRTs) on risk of cigarette smoking relapse by people who had already quit cigarettes.
Prospective cohort study.
The American Cancer Society Cancer Prevention Study-3, a nationwide US cohort with follow-up every 3 years beginning in 2015.
Adults who in 2015 had already quit smoking (n=3112) or were smoking (n=1018) and who in 2018 reported past or current exclusive use of ENDS or NRT and provided smoking status.
Relapse to cigarette smoking in 2018 among people who were already quit in 2015, and abstinence from cigarettes in 2018 among people who were smoking in 2015.
Among respondents who had already quit in 2015, the unadjusted risk of relapse in 2018 was approximately three times greater for those who reported past exclusive ENDS versus past exclusive NRT use (11.2% vs 3.9%; relative risk (RR)=2.90, 95% CI 2.12 to 3.98). This association remained significant in a multivariable-adjusted model (RR=2.09, 95% CI 1.49 to 2.92). Among those smoking in 2015, the unadjusted likelihood of abstinence in 2018 was higher for those who reported current ENDS versus NRT use (RR=1.35, 95% CI 1.01 to 1.80), but the multivariable model adjusted for smoking frequency indicated no difference in abstinence (RR=1.38; 95% CI 0.93 to 2.05).
ENDS use was associated with greater relapse risk than NRT among people who had already quit. Although ENDS may support shorter-term cessation, further long-term observational research is needed to clarify relapse risks associated with ENDS relative to NRT.

ObjectivesThis study aimed to longitudinally examine nationwide changes in smoking behavior among the Japanese population in response to the COVID-19 pandemic.
Design and settingA secondary analysis was conducted using cigarette sales data from the Tobacco Institute of Japan, monthly tobacco expenditures from the Family Income and Expenditure Survey conducted by the Ministry of Internal Affairs and Communications, and smoking prevalences from the National Database of Open Data Japan. An interrupted time-series segmented regression model adjusted for seasonality and autocorrelation was used to examine changes in cigarette sales and monthly tobacco expenditures before and after the first declaration of a state of emergency.
ParticipantsDepending on the data source, data from 2014 to 2022, from 2015 to 2025, or from 2015 to February 2026 were used.
Primary and secondary outcome measuresChanges in level and slope were evaluated before and after the first state of emergency and after COVID-19 was downgraded to a common infectious disease.
ResultsCigarette sales declined at a significantly slower rate after the first state of emergency than before. Price-adjusted monthly tobacco expenditures increased significantly by 132 JPY compared with the previous month, although the expenditure findings were less robust in the quadratic sensitivity analysis. The smoking prevalence among men declined slightly each year, from 34.2% in 2014 to 31.9% in 2022. In contrast, the smoking prevalence among women remained relatively stable, ranging between 9.4% and 9.9%.
ConclusionsAlthough cigarette sales declined more slowly and household tobacco expenditures increased during the first state of emergency in Japan, smoking prevalences did not change substantially. These findings suggest changes in tobacco purchasing patterns, including stockpiling, and possible changes in smoking intensity among continuing smokers, rather than a meaningful population-level decline in smoking behavior. There was no robust evidence of a clear reversal after May 2023.
Complex perianal fistulas are difficult to treat because of high recurrence rates and the need to preserve sphincter function. Negative pressure wound therapy (NPWT) improves healing in complex wounds, but its role in perianal fistula surgery is not well defined. This case series evaluated the feasibility, safety and early clinical outcomes of NPWT following surgical excision of complex perianal fistula tracts. A retrospective case series was conducted including eight adults with high or otherwise complex cryptoglandular perianal fistulas treated by surgical debridement followed by portable NPWT. Outcomes assessed were time to epithelialisation, symptom resolution, recurrence, complications and NPWT-related technical issues and refinements. Seven of eight patients achieved complete epithelialisation of the perianal wound after NPWT. One patient developed recurrence and required ongoing seton drainage. Over the course of the series, optimisation of sealing, sponge contouring and use of a bridge technique improved dressing reliability and wound progression. No NPWT device-related adverse events were observed. NPWT appears to be a feasible, well tolerated adjunct to surgery for complex cryptoglandular perianal fistulas, with high early healing rates and no device complications in this small series. Larger prospective studies are warranted to confirm efficacy and define optimal technical parameters.
With the rapid increase in the ageing population, the use of procedural sedation and analgesia (PSA) for diagnostic procedures such as prostate biopsy in older adults is increasing. However, elderly patients are particularly susceptible to respiratory depression during PSA testing and have a significantly higher risk of hypoxaemia during procedures requiring deep sedation. Although propofol combined with fentanyl is commonly used, it frequently causes hypoxaemia and apnoea. Remimazolam, a novel ultrashort-acting benzodiazepine, may be a safer alternative with less respiratory compromise; however, the supporting evidence remains limited. This study aims to assess whether remimazolam combined with fentanyl reduces the incidence of respiratory depression compared with propofol combined with fentanyl in elderly patients undergoing prostate biopsy under deep sedation requiring immobility.
This is a single-centre, participant and assessor-blinded (with pragmatic blinding of participants), parallel-group, superiority randomised controlled trial conducted at the Jichi Medical University Saitama Medical Centre, Japan. Eligible participants are men aged ≥70 years who are scheduled to undergo prostate biopsy under intravenous sedation. Participants will be randomised in a 1:1 ratio to receive either remimazolam or propofol, each administered in combination with fentanyl at a fixed effect-site concentration. The primary outcome is the incidence of severe apnoea (≥1 min). The primary analysis will follow the intention-to-treat principle, implemented practically as a full analysis set analysed using a complete case approach. Sensitivity analyses will include a per-protocol analysis and multiple imputations of missing data. A subgroup analysis of patients aged ≥75 years was performed.
This study was approved by the Jichi Medical University Central Clinical Research Ethics Committee (approval number: 24JMU001S-2) and was registered with the Japan Registry of Clinical Trials on 11 November 2024. Written informed consent was obtained from all participants before enrolment. These findings will be disseminated through publications in peer-reviewed journals and presentations at scientific conferences.

Landslides threaten sustainable development through economic and human losses. This study integrates machine learning methods to construct susceptibility maps, including topographic-hydrological indicators, to improve the inclusion of earthflow landslides. Furthermore, we aim to find relationships between landslide susceptibility and social lag using Copula models and SHAP values. Results reveal differentiated dependence across different partitions. Specifically, we found regime-specific co-occurrences of high social lag and high landslide susceptibility areas in steep, deprived areas, contrasting resilient affluent zones. Educational deprivation emerges as the top vulnerability factor, followed by healthcare access, overcrowding, and housing deficits. Highlighting spatial inequities, the analysis advocates targeted interventions blending slope stabilization and social policies.To examine the characteristics of the health care needs corresponding to the medical care process and HR-QOL of women with cancer.
A descriptive design was adopted.
The study's participants were 122 women with cancer who completed a survey before and 6 months after treatment initiation. A principal component analysis (PCA) was conducted on a set of 12 health care satisfaction scores at each point. Correlations were examined between the resulting components and HR-QOL indicators, including subjective well-being, symptoms, symptom-related interference, anxiety and depression.
Most participants reported high health care satisfaction in both phases. PCA indicated the presence of 3 distinct domains: satisfaction with health care, health care management and supportive care. In both phases, these domains accounted for about 60% of the variance, while the remaining 40% was unexplained. Only satisfaction with health care was correlated with HR-QOL at both phases, with particularly strong associations observed for subjective well-being and depression at 6 months. Before treatment initiation, the item of ‘nursing care and practice’ received the highest average score, but demonstrated a negative loading on the component of ‘satisfaction with health care management’. The component of ‘satisfaction with supportive care needs’ was retained at both phases.
Health care plays a pivotal role in maintaining patients' quality of life, while supportive care and the integration of nursing practice within health care management remain essential.
High satisfaction scores do not necessarily mean that all health care needs are met. Addressing unmet needs from the perspective of HR-QOL and ensuring continuous supportive care throughout the treatment process is imperative.
Data provided by women with cancer was used.
The aim of this research was to describe factors that influence Intensive Care Unit liaison nurses' decision to stand down a medical emergency team call response. The decision to end a medical emergency team response for a deteriorating patient is referred to as the medical emergency team call stand-down decision. Intensive Care Unit liaison nurses, also known internationally as critical care outreach nurses, make medical emergency team call stand-down decisions in complex and challenging clinical environments. However, the factors influencing these decisions are not well described in the literature.
Exploratory descriptive qualitative study.
Seven Intensive Care Unit liaison nurses who attended medical emergency team calls in a large acute metropolitan tertiary referral public hospital, with a mature three-tiered rapid response system, were observed and interviewed. Observations of 50 medical emergency team call responses and 50 post medical emergency team call interviews were conducted between March 2022 and August 2022. Findings were analysed using inductive content analysis.
Intensive Care Unit liaison nurse decisions to stand down MET call responses were influenced by three intrinsic factors: (1) propositional knowledge, (2) experiential knowledge, (3) situational knowledge and information processing styles. Intensive Care Unit liaison nurses utilised these intrinsic factors to support their decision to terminate medical emergency team call response.
This study explored the intrinsic influences on individual Intensive Care Unit liaison nurses in deciding to end a medical emergency team call. By highlighting these individual influences on decision-making, the findings may be used to support medical emergency team responders educational needs and identification of potential heuristics and biases inherent in clinical decision-making which contribute to adverse events.
No patient or public contribution.
By understanding the influences on an individual's clinical decision-making, strategies can be put in place for educational development and support for experiential learning. The study highlights areas of potential bias and heuristic use that may lead to sub-optimal clinical decisions and increased risk for deteriorating patients. Research findings can be applied internationally to a range of rapid response systems and critical care outreach teams that respond to deteriorating patients.
The consolidated criteria for reporting qualitative research (COREQ) guidelines were used for reporting this study.
