Introduction
The aim of this scoping review is to connect theoretical research related to stress with practical applications to supervision experiences within allied health professions. Understanding the implications of stress between clinical supervisors and allied health students will allow for better insights to improve supervisory methods within clinical training, stronger mentorship and lead to better quality patient care.

Methods and analysis
This review is conducted according to Joanna Briggs Institute (JBI) methodology for scoping reviews, which includes defining the research question, developing inclusion criteria and searching for, selecting, extracting and analysing the evidence. A literature search will be conducted in MEDLINE (PubMed), CINAHL (EBSCO), ERIC (EBSCO), PsycINFO (EBSCO) and Embase (Elsevier), as well as various grey literature resources. Studies will be included if they focus on undergraduate or graduate allied health students in a clinical setting and allied health clinical educators, and report on outcomes related to stress dynamics between these two populations. Results will pass through title/abstract and full-text screening before data are extracted using a tool developed by the reviewers. Data will be analysed and summarised descriptively and presented in both tabular and narrative formats.

Ethics and dissemination
Ethical approval is not required for this scoping review. Results will be disseminated in peer-reviewed publications and professional conferences.

Trial registration number
The protocol was registered with Open Science Framework on 2 October 2024 (https://doi.org/10.17605/OSF.IO/REK7Z).

Introduction
The incidence of post-traumatic stress disorder (PTSD) in emergency trauma surgery patients is 24%, emphasising the urgent need for effective early interventions and treatments. Transauricular vagus nerve stimulation (ta-VNS) modulates the autonomic nervous system by stimulating the nucleus tractus solitarius while affecting PTSD-related neural networks, including the prefrontal cortex, hippocampus and amygdala, potentially offering new options for PTSD prevention and treatment. This study aims to evaluate the efficacy and safety of ta-VNS in preventing PTSD in emergency trauma surgery patients.

Methods and analysis
This multicentre, double-blind, randomised controlled study aims to evaluate the incidence of PTSD in emergency trauma surgery patients receiving either ta-VNS or sham stimulation. A total of 350 participants will be randomly assigned to receive either active or sham stimulation. The active group will undergo electrical stimulation of the left cymba conchae at 30 Hz with a pulse width of 250 µs, using a 30 s on/30 s off cycle. The intensity will start at 0.4 V, increasing in 0.4 V increments until a tingling sensation is detected, and will be adjusted to the highest tolerable level without causing pain. The initial intervention will begin once informed consent is obtained and randomisation is completed in the preoperative preparation room, continuing until the surgery is finished. For the four postoperative days, the intervention will be administered two times per day in 2-h sessions each morning and evening. The sham stimulation group will follow a similar procedure without actual stimulation. The primary outcome is the incidence of PTSD evaluated on postoperative day 30, with secondary outcomes including recovery quality, sleep quality, and adverse events.

Ethics and dissemination
The protocol received approval from Sir Run Run Shaw Hospital, affiliated with Zhejiang University School of Medicine, on 15 October 2024 (approval number: 20240562). The study will adhere to the Declaration of Helsinki guidelines, and written informed consent will be obtained from all participants. Results will be submitted to a peer-reviewed journal for publication.

Background
Many countries have addressed the global issue of nursing shortage by recruiting overseas nurses who are also qualified in the host country. Nevertheless, such nurses may encounter various obstacles in their personal and professional lives in the host country, leading to apprehensions about their perceptions of workplace safety in healthcare organisations.

Objective
This study investigated the current state of immigration-specific stress among overseas qualified nurses (OQNs) working in Japan and its impact on safety attitudes.

Settings
Invitation letters with a Quick Response (QR) code for a survey were sent to 119 hospitals across Japan that accepted OQNs as per the Ministry of Health, Labour and Welfare. Additionally, the survey QR code was shared with OQN-specific social media groups.

Participants
The inclusion criteria were being born and having received basic nursing education outside Japan, passing the Japanese national nursing examination, and current employment in the Japanese healthcare organisations. Valid responses were received from 214 OQNs.

Methods
Data were collected via an online survey, including the Demands of Immigration Scale and Safety Attitudes Questionnaire-Short Form (SAQ-SF) to measure stress and safety attitudes evaluation, respectively. Spearman’s correlation analysis and a generalised linear model were used to analyse the relationship between immigration-specific stress and safety attitudes as perceived by OQNs.

Results
The findings showed that various safety attitude dimensions were significantly impacted by stressors such as ‘Not at home’, ‘Occupation’ and ‘Discrimination’. Notably, ‘Occupation’ disadvantages perceived by OQNs significantly affected all the safety attitude dimensions, such as ‘Teamwork climate’ (B=–5.69, [–7.78, –3.60], p

Introduction
Yeast beta-glucan (YBG) are recognised for enhancing the immune system by activating macrophages, a key defence mechanism. Given the global prevalence and impact of upper respiratory tract infections (URTIs) on productivity and healthcare costs, YBG has shown promise as a potential therapeutic and preventive strategy for recurrent respiratory tract infections. However, little is known regarding the efficacy of YBG at lower dosages in relation to URTI, fatigue, immune response and uncertainties of how they affect the gut microbiota composition.

Methods and analysis
This 12-week randomised, double-blinded, placebo control, parallel-group clinical trial aims to evaluate the efficacy of YBG 1,3/1,6 on respiratory tract infection, fatigue, immune markers and gut health among adults with moderate stress. The study involves 198 adults aged 18–59 years with moderate stress levels as assessed using Perceived Stress Scale 10 (score 14–26) and Patient Health Questionnaire 9 (score ≥9); and had symptoms of common colds for the past 6 months as assessed using Jackson Cold Scale. These participants will be randomised into three groups, receiving YBG 1,3/1,6 at either 120 mg, 204 mg or a placebo. The outcomes measures include respiratory infection symptoms, fatigue, mood state and quality of life assessed using Wisconsin Upper Respiratory Symptoms Scale, Multidimensional Fatigue Inventory, Profile of Mood State and Short Form 36 Health Survey Questionnaire, respectively. In addition, full blood analysis and assessment of immune, inflammatory and oxidative stress biomarkers will be taken. Secondary outcome includes gut microbiota analysis using stool samples via 16S rRNA sequencing.

Ethics and dissemination
The research protocol of the study was reviewed and approved by the Research Ethics Committee of Universiti Kebangsaan Malaysia (UKM/PPI/111/8/JEP-2023–211). The findings will be disseminated to participants, healthcare professionals and researchers via conference presentations and peer-reviewed publications.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide. In most cases, HCC develops in an already perturbed liver microenvironment with pre-existing liver cirrhosis and tissue remodelling. Once a tumour nodule evolves, a complex ecosystem comprising tumour, immune, structural cells and extracellular matrix develops and forms the so-called tumour microenvironment (TME).1 This TME is shaped by distinct metabolic networks particularly driven by metabolic reprogramming of tumour cells, which supports their function, as one of the hallmarks of cancer.2 For example, in many cancer types, tumour cells mostly depend on glucose consumption for their energy supply, leading to lactate production and acidic conditions in the TME even with enough oxygen (Warburg effect).3 In addition, tumour cells also heavily rely on the amino acid glutamine (single letter code: Q) for their nucleotide biosynthesis and thus proliferation as well as for lipid biosynthesis and…

Introduction
Patients undergoing surgical procedures are often prone to developing acute stress disorder (ASD) postoperatively. Presently, oxytocin nasal spray has shown significant potential in the treatment of stress-related neuropsychiatric diseases. However, there are few reports on the use of oxytocin nasal spray in postoperative ASD, a condition that can potentially develop into a high-risk factor for post-traumatic stress disorder. This study aims to investigate the effect of pretreatment with oxytocin nasal spray on postoperative ASD in patients with accidental trauma and fracture to provide new clinical insights for the prevention of postoperative ASD.

Methods and analysis
This study is a single-centre, double-blind, randomised controlled clinical trial. The trial aims to recruit 328 patients with accidental traumatic fractures who underwent surgical treatment. Participants will be randomly categorised into two groups: a control group (0.9% normal saline nasal spray, 1 mL) and an oxytocin group (oxytocin nasal spray, 1 mL/40 IU) at a ratio of 1:1 using the random number table method. The primary outcome is the incidence of ASD on postoperative days 1–3. Secondary outcomes include patient resilience, anxiety, depression and pain scores on postoperative days 1–3. The exploratory results include the concentrations of stress response indicators such as malondialdehyde, cortisol and superoxide dismutase in the saliva before the first intervention and on days 1–3 after surgery.

Ethics and dissemination
The trial was approved by the clinical research ethics committee of the General Hospital of the Western Theater Command (identifier: 2024EC3-ky014). The findings of this trial will be disseminated in a peer-reviewed journal and in national or international paediatric research to guide future practice.
