This study developed and validated the precaution theory-based Environmental Parenting Scale (EPS) to assess proactive parental behaviours that reduce children’s environmental risk exposure. Existing measures lack theory-based assessments of preventive parenting under environmental uncertainty.

This study involves the development of a scale based on Kriebel’s precaution theory to construct measures of environmental parenting behaviour.

For exploratory factor analysis, 216 participants with children under the age of 18 were recruited from Jeonju, Cheonan and Milyang in South Korea between 16 September 2024 and 21 September 2024 using convenience sampling. Content validity was confirmed by three professionals.

The preliminary items were gathered through a literature review and in-depth interviews with 10 participants. We assessed convergence validity, known-group validity and internal consistency reliability. Exploratory factor analysis revealed a cumulative variance of 65.73% for explaining the target behaviours.

The EPS comprises 21 items across four factors: hygiene management, natural product use, prevention of toxin exposure and protection from radiation. Convergent validity with the personal environmental health behaviours scale was supported (r=0.75, p

The EPS is a valid and reliable scale for measuring environmental parenting behaviours in the context of climate change and environmental diseases.

Despite substantial research investments aiming to prevent cancer and develop therapeutic interventions, cancer remains a formidable challenge. In view of the persistent rise in cancer prevalence, the condition should also be recognised as a chronic disease. Such an approach can enhance the quality of life of patients with cancer, inhibit treatment-related adverse events and prevent recurrence via comprehensive post-treatment management. The core objective of this study is to investigate the association between dietary factors and treatment-related adverse events in patients with cancer, with the aim of providing individualised dietary recommendations to reduce adverse events and enhance quality of life.

The study cohort will include 600 participants aged ≥20 years. The participants will be assessed for dietary intake, cancer therapy-related adverse events and single-nucleotide polymorphisms using genomic DNA extracted from saliva. In addition, general and clinical information, lifestyle patterns and general/biochemical data of the blood will also be collected. The primary outcome is dietary factors that mitigate chemotherapeutic adverse events, and the secondary outcome is the association between nutritional status and survival in Korean patients with cancer. Considering the potential impact of dietary habits on the adverse events of cancer treatment, the findings of this study can be used as a basis for the establishment of new dietary guidelines for patients with cancer.

The Institutional Review Board of Severance Hospital, Yonsei University Health System, Seoul, Korea, approved the study protocol (4-2021-1110). Further, all participants provided a written informed consent prior to the study. The findings will be shared via publications.

Proximal gastrectomy (PG) has emerged as the preferred surgical approach for adenocarcinoma of the upper 1/3 stomach and selected cases of oesophagogastric junction adenocarcinoma. We developed a novel oesophagogastric anastomosis technique with an antireflux mechanism (Hao’s Esophagogastrostomy by Fissure Technique). It may have a superior effect on patient weight maintenance compared with the double-tract reconstruction. We intend to conduct a prospective, multicentre, randomised controlled clinical trial to validate this hypothesis.

The primary objective evaluates body weight loss at 12 months postoperatively. Secondary objectives assess surgical safety through comprehensive analysis of complication rates and nutritional parameters, including serial haematological evaluations during follow-up. The study will enrol 52 participants across multiple centres with planned 3-year longitudinal monitoring to evaluate both immediate postoperative outcomes and intermediate-term clinical impacts.

This study was approved by the hospital institutional review board of Huashan Hospital, Fudan University (2024-1173) and is being conducted in accordance with the Declaration of Helsinki and the Good Clinical Practice guidelines. On completion of the study, the results will be published in a peer-reviewed journal.
