This study aims to explore the history of prior abortions and the factors influencing them among young women seeking abortion services in Foshan, Guangdong, China.
This is a retrospective, cross-sectional study of young women seeking abortion care.
Gynaecological outpatient clinics at the Department of Gynaecology, Foshan Women and Children Hospital Affiliated to Guangdong Medical University, Foshan, Guangdong, China, between 2013 and 2023.
A total of 7361 young women aged 12–25 years seeking abortion services.
Data on abortion history, sociodemographic factors, contraceptive use and postabortion contraceptive choices were collected and analysed, with special emphasis on the incidence of repeat abortions and the factors associated with them.
Of the 7361 participants, 34.2% reported at least one previous abortion, underscoring a notable public health concern. The mean age of the participants was 22.30 years (SD=2.13). Women with a history of abortion were significantly older than those without (22.57 vs 22.08 years, p
This study underscores the need for targeted interventions to address the multifaceted factors leading to repeat abortions among young women in China. The results offer valuable insights for improving reproductive health outcomes in this vulnerable population and highlight the importance of expanding access to contraceptive education and services in China.
To evaluate the relationship between preoperative COVID-19 infection and major postoperative pulmonary complications (PPC) risk after major elective surgeries during the Omicron wave.
A multicentre, prospective, observational cohort study.
Four tertiary medical centres in Beijing, China.
All adult patients who underwent major elective surgeries under general anaesthesia from 30 December 2022 to 18 May 2023 were screened for eligibility. A total of 3211 patients were included.
The primary outcome was 30-day major PPC, defined as pneumonia, acute respiratory distress syndrome or unexpected postoperative ventilation. The secondary outcomes included length of hospital stay (LOS), reoperation and mortality.
Major PPC occurred in 3.5% of patients with preoperative COVID-19 and 3.3% of those without. Inverse probability of treatment weighting-adjusted analysis showed no significant association between preoperative COVID-19 within 12 weeks and PPC risk (adjusted OR, 0.89; 95% CI 0.69 to 1.13). However, multivariable analysis revealed that COVID-19 infection within 3 weeks was independently associated with an increased PPC risk (OR, 3.44; 95% CI 1.37 to 8.68). Cardiothoracic surgery (OR, 12.47; 95% CI 8.11 to 19.17) and longer duration of surgery (OR, 1.24 per hour; 95% CI 1.13 to 1.37) were significant risk factors. In the cardiothoracic subgroup, PPC risk was significantly elevated within 7 weeks of infection. No significant differences were observed in LOS, reoperation rates or mortality between patients with and without preoperative COVID-19 infection.
Preoperative COVID-19 infection within 12 weeks was not associated with an increased overall risk of major PPC during the Omicron wave. Although very short infection-to-surgery intervals and cardiothoracic surgery showed exploratory signals of higher risk, these findings should be interpreted cautiously and support an individualised approach to perioperative risk assessment.

To evaluate the prognostic significance of tumour deposit (TD) across different N stages in patients with stage III colon cancer and to develop and validate a novel N staging system that incorporates TD count to improve prediction of cancer-specific survival (CSS).
Retrospective cohort study based on population-based data and external validation.
Secondary and tertiary care settings; data from the SEER database, a population-based cancer registry capturing cancer incidence and survival information (USA, 2010–2017); and a single-centre validation cohort from South China (2015–2019).
A total of 8739 stage III colon cancer patients from the SEER database who underwent curative surgery were included; 1335 (15.3%) had TD. Patients with
The outcome was cancer-specific survival (CSS). The prognostic impact of tumour deposit (TD) and the comparative performance of the novel N staging system versus the AJCC system were evaluated using the Fine-Gray competing risks model, time-dependent area under the curve (AUC) and Brier score.
TD was independently associated with poorer CSS: 1 TD (SHR=1.23, 95% CI 1.04 to 1.47, p=0.017), 2–3 TDs (SHR=1.36, 95% CI 1.17 to 1.58, p3 TDs (SHR=2.02, 95% CI 1.73 to 2.35, pet al, TDs were converted to metastatic lymph nodes (mLNs) using the following weighting: 1 TD=3 mLNs (N1c), 1 TD=2 mLNs (N1) and 1 TD=1 mLN (N2). The novel N staging system stratified patients as nN1a (1 nLN), nN1b (2–3 nLNs), nN2a (4–6 nLNs) and nN2b (≥7 nLNs). This approach showed improved prognostic accuracy compared with AJCC N staging: 3-year AUC (0.623 vs 0.614) and Brier score (0.151 vs 0.157, p
TD significantly worsens prognosis in stage III colon cancer, particularly in lower N stages. Incorporating TD counts into the N staging system with different weightings based on N stage enhances prognostic accuracy and risk stratification within stage III disease, particularly for the heterogeneous AJC N1c category. This novel staging system provides better prognostic value and more accurate treatment guidance and should be considered for broader clinical use, subject to further (eg, prospective) validation.

Iodine-based antiseptics are essential in wound care but are often limited by cytotoxicity, instability, and rapid iodine release. Novostron is a novel polymer–iodine complex incorporating dextrin, polyvinyl alcohol, and metal ions, designed to enable controlled iodine release. Structural integrity and composition were confirmed by ¹H and 13C NMR spectroscopy and physicochemical analysis, indicating a molecular weight of ~9500 g/mol, a pH of 4.23, and an iodine content of 8.13%. Pharmacokinetic analysis in rabbits demonstrated that following a single dermal application, systemic iodine absorption was minimal, with peak blood iodine concentrations remaining within physiological limits and rapid elimination within 24 hours. Evaluation of thyroid function revealed no significant changes in serum T₃, T₄, or TSH levels compared with those of the controls, confirming that topical application of Novostron does not disrupt thyroid homeostasis. In compliance with OECD guidelines in rabbits, guinea pigs, and rats, Novostron showed no signs of dermal irritation, skin sensitization, or systemic toxicity (LD₅₀ > 2000 mg/kg). In a rat cotton pellet granuloma model, Novostron significantly reduced the inflammatory mass (23.65% inhibition), supporting its anti-inflammatory potential. In a murine burn model, Novostron accelerated wound contraction (25.95% at day 10), increased epidermal thickness, and enhanced collagen deposition (~44%), outperforming controls and matching or exceeding betadine. These findings suggest that Novostron promotes tissue repair by modulating inflammation. Overall, Novostron demonstrated a favourable preclinical safety and efficacy profile, and its polymer–iodine composition, which enables controlled release and localized activity highlights its potential as a promising topical therapeutic. However, the study was limited to animal models and short-term observation; further long-term and clinical investigations are needed to confirm its translational potential in human wound healing.The best evidence on programmed weaning from mechanical ventilation in neurocritical care patients should be gathered, evaluated, and integrated to provide an evidence basis for determining the optimal weaning program for these patients.
According to the ‘6S’ pyramid model of evidence-based practice resources, Chinese and international guideline websites, websites of relevant professional societies, and Chinese and English databases were systematically searched. The databases were searched from the time of establishment to October 2024. Literature screening was subsequently performed according to the inclusion and exclusion criteria. Two researchers independently evaluated the literature quality and extracted and summarised the evidence.
A total of 21 publications were included, including 3 guidelines, 5 expert consensus papers, 1 evidence summary, and 12 systematic reviews. A total of 29 pieces of best evidence in the following 5 aspects were summarised: preweaning preparation and screening, a weaning protocol, extubation assessment, extubation preparation and procedure, and postextubation management.
This study summarises the best evidence for the programmed weaning of neurocritical care patients from mechanical ventilation and provides a basis for clinical medical personnel to standardise this weaning process. Evidence-based application of these strategies should be implemented to verify their clinical efficacy and safety in practice.
Successful weaning is key in the management of neurocritical care patients receiving mechanical ventilation. The establishment of a localised extubation protocol guided by a multidisciplinary team can significantly reduce the extubation failure rate, the duration of mechanical ventilation and the incidence of related complications. However, evidence-based application is needed to verify the efficacy and safety of these strategies in clinical practice.
This evidence review adhered to the evidence review report guidelines formulated by the Evidence-Based Nursing Center of Fudan University. These guidelines cover aspects such as problem establishment, literature search, literature screening, literature evaluation, evidence summary and classification, as well as the formulation of practical suggestions. This evidence summary followed the evidence summary reporting specifications of the Fudan University Center for Evidence-Based Nursing (http://ebn.nursing.fudan.edu.cn) with registration number ES20244849.

This study aims to examine the chain-mediating effects of affective reactions and burnout on the relationship between workplace violence and work performance among nurses while distinguishing between physical and psychological violence.
A longitudinal study was conducted between October 2020 and October 2022. The study took place in four tertiary hospitals of Shandong Province, China. A total of 1086 nurses were recruited.
Workplace psychological violence, workplace physical violence, work performance, affective reactions (including anxiety and depressive symptoms) and burnout were assessed using self-report questionnaires. Data were analysed using multiple linear regressions and structural equation modelling on SPSS and AMOS.
The STROBE checklist was used for this study.
Workplace psychological violence, but not physical violence, was associated with nurses' work performance. Burnout mediates the relationship between workplace psychological violence and work performance. Affective reactions and burnout play serial intermediary roles in the relationship between workplace psychological violence and work performance.
Interventions aimed at reducing anxiety, depressive symptoms, and burnout among nurses who have experienced psychological violence may enhance their work performance.
Hospital administrators should prioritise the development of strategies to prevent psychological violence (e.g., anti-bullying training and counselling support) and enhance nurse performance through burnout screening and targeted interventions.
This study was conducted in Shandong Province, China, and relied on self-reported data, which may be subject to social desirability bias.
No patient or public contribution.
