Amphibian skin is integral to promoting normal physiological processes in the body and promotes both innate and adaptive immunity against pathogens. The amphibian skin microbiota is comprised of a complex assemblage of microbes and is shaped by internal host characteristics and external influences. Skin disease is a significant source of morbidity and mortality in amphibians, and increasing research has shown that the amphibian skin microbiota is an important component in host health. The Eastern hellbender (Cryptobranchus alleganiensis alleganiensis) is a giant salamander declining in many parts of its range, and captive-rearing programs are important to hellbender recovery efforts. Survival rates of juvenile hellbenders in captive-rearing programs are highly variable, and mortality rates are overall poorly understood. Deceased juvenile hellbenders often present with low body condition and skin abnormalities. To investigate potential links between the skin microbiota and body condition, we collected skin swab samples from 116 juvenile hellbenders and water samples from two holding tanks in a captive-rearing program. We used 16s rRNA gene sequencing to characterize the skin and water microbiota and observed significant differences in the skin microbiota by weight class and tank. The skin microbiota of hellbenders that were housed in tanks in close proximity were generally more similar than those housed physically distant. A single taxa, Parcubacteria, was differentially abundant by weight class only and observed in higher abundance in low weight hellbenders. These results suggest a specific association between this taxa and Low weight hellbenders. Additional research is needed to investigate how husbandry factors and potential pathogenic organisms, such as Parcubacteria, impact the skin microbiota of hellbenders and ultimately morbidity and mortality in the species.by Mireia Solé Pi, Luz A.

A long-standing question in the study of quantity discrimination is what stimulus properties are controlling choice. While some species have been found to do it based on the total amount of stimuli and without using numerical information, others prefer numeric rather than any continuous magnitude. Here, we tested cats, dogs, and humans using a simple two-way spontaneous choice paradigm (involving food for the first two, images for the latter) to see whether numerosity or total surface area has a greater influence on their decision. We found that cats showed preference for the larger amount of food when the ratio between the stimuli was 0.5, but not when it was 0.67; dogs did not differentiate between stimuli presenting the two options (smaller vs. larger amount of food) regardless of the ratio between them, but humans did so almost perfectly. When faced with two stimuli of the same area but different shapes, dogs and humans exhibited a preference for certain shapes, particularly the circle, while cats’ choices seemed to be at chance level. Furthermore, cats’ and dogs’ reaction times were equal across conditions, while humans were quicker when choosing between stimuli in trials where the shape was the same, but the surface area was different, and even more so when asked to choose between two differently sized circle shapes. Results suggest that there is no universal rule regarding how to process quantity, but rather that quantity estimation seems to be tied to the ecological context of each species. Future work should focus on testing quantity estimation in different contexts and different sources of motivation.Parkinson’s disease is a neurological disease with a rising incidence and prevalence. Patients with Parkinson’s disease may receive antipsychotics, for example, due to Parkinson’s disease psychosis. Parkinson’s disease psychosis is characterised by visual hallucinations and other psychotic symptoms. To date, no systematic review has evaluated the effects of antipsychotics in patients with Parkinson’s disease. Therefore, this review aims to assess the beneficial and harmful effects of antipsychotics for Parkinson’s disease.
This is a protocol for a systematic review. A search specialist will perform a search in major medical databases (eg, MEDLINE (Medical Literature Analysis and Retrieval System Online), EMBASE (Excerpta Medica database), CENTRAL (Cochrane Central Register of Controlled Trials)) and clinical trial registries. Published and unpublished randomised clinical trials comparing antipsychotics to any control (placebo, standard care or other antipsychotics) in patients with Parkinson’s disease will be included. Two review authors will independently extract data and conduct risk of bias assessments with the Cochrane Risk of Bias tool—V.2. Primary outcomes will be all-cause mortality, serious adverse events and significant falls. Secondary outcomes will be hospitalisations, non-serious adverse events, Unified Parkinson’s Disease Rating Scale total score and psychotic symptoms using any valid symptom scale. Data will be synthesised by aggregate meta-analysis, trial sequential analysis and network meta-analysis. Several subgroup analyses are planned. An eight-step procedure will be used to assess if the thresholds for clinical significance are crossed, and the certainty of the evidence will be assessed by GRADE (Grading of Recommendations Assessment, Development and Evaluations) and CiNeMA (Confidence in Network Meta-Analysis) approach.
This protocol does not include results, and ethics approval is not required for the project. The findings from the systematic review will be published in international peer-reviewed scientific journals.

To increase the sustainability of healthcare, clinical trials must assess the environmental impact of interventions alongside clinical outcomes. This should be guided by Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) and Consolidated Standards of Reporting Trials (CONSORT) extensions, which will be developed by The Implementing Climate and Environmental Outcomes in Trials Group. The objective of the scoping review is to describe the existing methods for reporting and measuring environmental outcomes in randomised trials. The results will be used to inform the future development of the SPIRIT and CONSORT extensions on environmental outcomes (SPIRIT-ICE and CONSORT-ICE).
This protocol outlines the methodology for a scoping review, which will be conducted in two distinct sections: (1) identifying any existing guidelines, reviews or methodological studies describing environmental impacts of interventions and (2) identifying how environmental outcomes are reported in randomised trial protocols and trial results. A search specialist will search major medical databases, reference lists of trial publications and clinical trial registries to identify relevant publications. Data from the included studies will be extracted independently by two review authors. Based on the results, a preliminary list of items for the SPIRIT and CONSORT extensions will be developed.
This study does not include any human participants, and ethics approval is not required according to the Declaration of Helsinki. The findings from the scoping review will be published in international peer-reviewed journals, and the findings will be used to inform the design of a Delphi survey of relevant stakeholders.

The WHO has declared climate change the defining public health challenge of the 21st century. Incorporating climate and environmental outcomes in randomised trials is essential for enhancing healthcare treatments’ sustainability and safeguarding global health. To implement such outcomes, it is necessary to establish a framework for unbiased and transparent planning and reporting. We aim to develop extensions to the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT 2025) and Consolidated Standards of Reporting Trials (CONSORT 2025) statements by introducing guidelines for reporting climate and environmental outcomes.
This is a protocol for SPIRIT and CONSORT extensions on reporting climate and environmental outcomes in randomised trials termed SPIRIT-Implementing Climate and Environmental (ICE) and CONSORT-ICE. The development of the extensions will consist of five phases: phase 1—project launch, phase 2—review of the literature, phase 3—Delphi survey, phase 4—consensus meeting and phase 5—dissemination and implementation. The phases are expected to overlap. The SPIRIT-ICE and CONSORT-ICE extensions will be developed in parallel. The extensions will guide researchers on how and what to report when assessing climate and environmental outcomes.
The protocol was submitted to the Danish Research Ethics Committees, Denmark in June 2025. Ethics approval is expected in September 2025. The SPIRIT and CONSORT extensions will be published in international peer-reviewed journals.
Fathers of preterm infants wish to be actively involved and attentive in caring for their children. The positive impacts of paternal caregiving on preterm infants’ cognitive and social development have been recognised. Awareness of the need to support fathers during early parenthood is increasing, but fathers may feel excluded when their infants are in the neonatal intensive care unit. Here, we present the protocol for a study involving the development and national implementation of a complex intervention supporting first-time fathers of preterm infants in early parenthood.
The study adheres to the Medical Research Council framework for complex interventions. A multicentre, prospective, non-blinded, quasi-experimental design will be applied to evaluate the effect of a clinical and technology-based intervention targeting both nurses and the fathers. Outcomes from participants enrolled during the control (2023–2024) and intervention (2025–2026) periods, comprising 295 fathers and their partners, will be compared. Effects on parental confidence, stress, depression and mood and family and reflective functioning as well as infants’ emotional and social development will be assessed. A comprehensive process evaluation will be applied using both qualitative and quantitative methods.
The study has been registered at Clinicaltrials.org [no. NCT0 6 116 747 (The SUPPORTED study – First-time Fathers of Preterm Infants), approved on 3 November 2023]. The Danish Data Protection Agency has approved the study (P-2022–792). The findings will be disseminated through peer-reviewed publications.
Given that low retention rates are a prevalent challenge in clinical trials, which ultimately affects trial validity, it is recommended that interventions be developed and evaluated to increase trial retention. In the context of trial retention, incorporating behavioural science is endorsed, as it provides a theoretical foundation for considering human behaviour. We hypothesised that an intervention informed by self-determination theory could increase retention in a randomised allergy trial on intralymphatic immunotherapy, as the support of basic psychological needs for autonomy, competence and relatedness is anticipated to lead to more sustained engagement and better outcomes.
To assess the acceptability and feasibility of the intervention and evaluation design, following the complex intervention framework by the Medical Research Council, before proceeding to a randomised evaluation.
A parallel two-arm randomised feasibility study was conducted within the randomised allergy trial.
All participants at one Danish site were eligible for recruitment.
The intervention was a web app informed by self-determination theory to support the basic psychological needs through its thoughtfully designed features. Participants were allocated unblinded across treatment groups to complete daily online questionnaires over a 100-day period from May to August 2022. All participants received a daily text message with a link for the questionnaires. On completion, participants in the control group received a confirmation message, while participants in the intervention group had a browser with the menu of the web app opened for them. The features within the menu were voluntary to use.
The prespecified assessments included evaluating the recruitment rate, retention rate (which reflected both sustained participation and the proportion of completed daily questionnaire entries), the suitability of outcome measures and the acceptability of the intervention and evaluation design to both participants and staff. Qualitative data were collected through a collaborative learning process with participants from the intervention group in November 2022.
A total of 30 participants were invited, randomly assigned 1:1 and analysed, resulting in a recruitment rate of 100%. None were lost to follow-up as all remained in the study for the entire duration. The response rate was 84.5% in the intervention group and 79.1% in the control group, indicating satisfactory retention. Outcome measures were deemed appropriate. No unintended adverse events were identified. The collaborative learning meetings involved three participants in the first meeting and two in the second, comprising a total of five different individuals. Participants found the intervention acceptable. They used it differently but agreed that its components were useful. Technical issues needed fixing, and voluntary free text boxes and registration of medication dosage should be added.
The intervention and evaluation design were assessed as acceptable and feasible. Technical issues were fixed, and additional response options were added before a randomised evaluation.

Gestational diabetes mellitus (GDM) is common in pregnancy and is increasing in prevalence. It is associated with an increased risk of maternal and perinatal complications if not diagnosed and managed early. Most guidelines suggest making a diagnosis of GDM using an oral glucose tolerance test (OGTT) between 24 and 28 weeks of pregnancy at which stage there still is an increased risk of complications. Increased beta-cell secretory product concentrations have been observed prior to changes in glycaemia and can potentially be used as an early marker to diagnose and assess risk of developing GDM.
The study was a prospective, longitudinal cohort study. OGTTs were carried out at visit one: 16–18 weeks and visit two: 24–28 weeks gestation in pregnant women with at least one risk factor for GDM [Body Mass Index >30 kg/m2, previous macrosomic baby (>4.5 kg), previous GDM, first degree relative with type 2 diabetes mellitus (T2DM)]. Blood sampling was performed at fasting, 30 min, 1 and 2 hours following a 75-g oral glucose load. Samples were analysed for glucose, total and intact proinsulin, insulin and C-peptide. Hormonal concentrations at visit 1 were compared between those that remained normal glucose tolerant (NGT) and those that progressed to GDM at visit 2 using receiver operator characteristic (ROC) area under the curve (AUC) to assess for discrimination between the two groups.
Unfortunately, a smaller than planned sample size was recruited due to the start of COVID-19 pandemic midway through the study. 83 pregnant women had OGTT at visit 1. Of these, 12 reached the threshold for GDM at visit 1 and were excluded. In total, data from 66 patients were included for analysis (5 Did Not Attend). Visit 1 hormone comparisons were carried out between 51 who remained NGT and 15 who progressed to GDM at visit 2. There were no significant differences at each time point in ROC AUC between the two groups for total and intact proinsulin and insulin. However, there were significant differences observed in C-peptide ROC AUC at 30 (p=0.041) and 60 min (p=0.003) between the two groups.
This study did not demonstrate significant increase in early proinsulin concentrations in patients that developed GDM. However, there were differences in C-peptide concentrations. The COVID-19 pandemic restricted the recruitment of patient numbers and further studies in a larger cohort will be needed to validate these findings.
To co-produce a prototype intervention to help nurses improve the assessment and care of the sexual health needs of men with inflammatory bowel disease.
Inflammatory bowel disease can have a significant impact on the sexual health and well-being of men, but has largely been neglected in research and clinical guidelines. Men with the disease report that sexual health is not discussed during consultations, while healthcare practitioners describe a lack of confidence to initiate sexual health assessments. At present, no evidence-based tool exists to support nurses in detecting, assessing, and providing care for the sexual health of men with the disease.
A mixed-methods study shaped by phase 1 of the Medical Research Council's framework for the development of complex interventions.
(1) Cross-sectional surveys of (i) men with inflammatory bowel disease, (ii) nurses, and (iii) inflammatory bowel disease services to determine the current state of sexual health provision across the UK National Health Service. (2) Semi-structured interviews with men and the partners of men with IBD and asynchronous focus groups with health professionals to explore appropriate and acceptable ways to provide sexual healthcare. (3) Three consecutive co-production workshops inclusive of men with the disease, healthcare professionals, and stakeholders to formulate a prototype intervention.
This study will create an evidence-based prototype intervention that will provide nurses with the knowledge and skills required to effectively assess the sexual health needs of men with inflammatory bowel disease and provide appropriate, patient-centred care.
The study design was supported by a patient group. The study delivery will be supported by a patient co-investigator and stakeholder group inclusive of men with lived experience of the disease.
This report adheres to the SPIRIT 2013 checklist for standard protocol items for clinical trials.

To explore the experiences of significant others of patients with severe burn injury in the intensive care unit. Specifically, how severe burn injury impacted the significant other and their role within their loved one's life.
This qualitative study employed a Narrative Inquiry approach.
Interviews were undertaken during 2021–2022 with 17 participants who were the significant others of a patient with severe burn injury in the Intensive Care Unit. Recruitment occurred in New South Wales, Australia, from two tertiary hospitals providing care for people with major burns. A narrative inquiry approach was utilised, capturing stories through semi-structured interviews.
Significant others experienced necessary changes in their life in response to the catastrophe. These included advocating, being present and ensuring their loved one's needs were met, while often neglecting themselves. Significant others contemplated their future as a carer to their loved one with severe burn injury, and adjusting their own career, finances and lifestyle, often as a long-term measure. The shifting of their role to carer ultimately transformed and redefined their relationships and lives.
Significant others endure immense trauma when a loved one sustains a severe burn injury. They require support but prioritise the patient by virtue of their critical illness. The life of the significant other is changed as they take on the role of carer and provide support. It is, therefore, imperative that the support needs of significant others are recognised, understood and addressed to ensure their well-being while processing the trauma.
With increased understanding of the significant others' experiences, healthcare providers can adopt a consultative approach, where roles and boundaries can be clearly identified. Through this process, healthcare providers can strengthen rapport and provide targeted support for significant others, as they navigate this traumatic life-altering event.

Intrathoracic cancers, such as lung cancer, mesothelioma and thymoma, represent diagnostic challenges in primary care. We aimed to summarise evidence on the performance of imaging techniques that could aid the detection of intrathoracic cancers in low prevalence settings.
Systematic review and quality appraisal using Quality Assessment of Diagnostic Accuracy Studies-2 and Grading of Recommendations Assessment, Development and Evaluation.
MEDLINE, Embase and Web of Science were searched with a predesigned search strategy for articles from January 2000 to January 2024.
We included studies relevant for primary care, where participants were suspected of having intrathoracic cancer and reported on at least one diagnostic performance measure. We excluded studies where the cancer diagnosis was already established. Data extraction and synthesis screening were conducted independently by two reviewers. Data extraction and quality appraisal were conducted by one reviewer and checked by a second reviewer.
Out of 30 539 records identified by the database searches, 13 studies were included. There was heterogeneity in the types of cancers, populations included and reported diagnosis pathways for suspected cancers. Imaging modalities investigated included chest X-ray (three studies), computer tomography (CT, six studies), magnetic resonance imaging (two studies), positron emission tomography CT (two studies), ultrasound (two studies) and scintigraphy (one study). Chest X-ray sensitivity reported for lung cancer ranged from 33.3% to 75.9%, with specificity ranging from 83.2% to 95.5%. For CT, reported sensitivity varied from 58% for pleural malignancy to 100% for lung cancer. One study investigating an artificial intelligence tool to detect lung cancer found poor detection performance in a real-world patient cohort.
We found a limited number of studies reporting on the diagnostic performance of usual imaging techniques when used in unselected primary care settings for the diagnosis of intrathoracic cancer in symptomatic patients. There is a need for more studies evaluating such techniques in the general population presenting in primary care, where the prevalence is relatively low. A better understanding of the performance could lead to better detection strategies for intrathoracic cancers in primary care. Intrathoracic cancers, such as lung cancer, mesothelioma and thymoma, represent diagnostic challenges in primary care. We aimed to summarise evidence on the performance of imaging techniques that could aid the detection of intrathoracic cancers in low prevalence settings.
Recent studies have demonstrated a beneficial role of steroids in severe community-acquired pneumonia, severe COVID-19 infection and acute respiratory distress syndrome (ARDS) of diverse aetiology. This multicentre randomised controlled trial in severe scrub typhus pneumonitis and ARDS will compare the effects of 6 mg of dexamethasone once per day with placebo, in addition to standard treatment, on ventilator-free days (VFD), mortality and ventilatory requirement.
The study, involving six sites, will recruit 440 patients with severe scrub typhus pneumonitis or ARDS to concealed, block-randomised, site-specific assignment of dexamethasone or placebo for 4–7 days. The primary outcome will be VFD, defined as days alive and free of ventilation at 28 days. Secondary outcomes will include 28-day mortality, need and duration of ventilation, and treatment failure, defined as death, or escalation of respiratory support from simple devices (nasal cannula, mask) to non-invasive or invasive ventilation, or the use of open-labelled steroids for worsening shock. The study will also ascertain if antinuclear antibody (ANA) expression during the acute phase of illness will predict steroid responsiveness. Subgroup analyses will be conducted a priori on ANA expression and the need for ventilation. All analyses will be conducted on an intention-to-treat basis. The trial, which commenced in April 2025, would clarify the role of corticosteroids in scrub typhus pneumonitis.
The Institutional Review Board and Ethics Committee of the lead site, Christian Medical College, Vellore, India, has approved the study (IRB Min No 15920 (INTERVE) dated 22 November 2023). The remaining five sites have obtained approval from their respective ethics committees. Study results will be published in an international peer-reviewed journal.

Scoping reviews, mapping reviews and evidence and gap maps (collectively known as ‘big picture reviews’) in health continue to gain popularity within the evidence ecosystem. These big-picture reviews are beneficial for policy-makers, guideline developers and researchers within the field of health for understanding the available evidence, characteristics, concepts and research gaps, which are often needed to support the development of policies, guidelines and practice. However, these reviews often face criticism related to poor and inconsistent methodological conduct and reporting. There is a need to understand which areas of these reviews require further methodological clarification and exploration. The aim of this project is to develop a research agenda for scoping reviews, mapping reviews and evidence and gap maps in health by identifying and prioritising specific research questions related to methodological uncertainties.
A modified e-Delphi process will be adopted. Participants (anticipated N=100) will include patients, clinicians, the public, researchers and others invested in creating a strategic research agenda for these reviews. This Delphi will be completed in four consecutive stages, including a survey collecting the methodological uncertainties for each of the big picture reviews, the development of research questions based on that survey and two further surveys and four workshops to prioritise the research questions.
This study was approved by the University of Adelaide Human Research Ethics Committee (H-2024-188). The results will be communicated through open-access peer-reviewed publications and conferences. Videos and infographics will be developed and placed on the JBI (previously Joanna Briggs Institute) Scoping Review Network webpage.
This study aimed to co-design a model of brilliant care for older people that provides clear, actionable principles to guide how brilliant care for older people can be realised.
As the demand for and international importance of care for older people grows, so too does the negative discourse about care for older people. This ongoing focus on deficiencies can have implications for patients, carers, clinicians, health services, and policymakers, overshadowing opportunities for innovation and positive change.
Experience-based co-design informed this study, grounded in the lived experiences of key stakeholders.
Three scaffolded co-design workshops were facilitated, involving lived experience experts, managers, professionals, clinicians, and an academic (n= 13). The data collected during these workshops were analysed using a qualitative descriptive method and documented according to COREQ guidelines to optimise rigour and transparency.
The participants co-designed a model of brilliant care for older people, comprising principles to promote connection and innovation. To promote connection, the model includes protecting staff member time to deliver meaningful care and demonstrating that everyone matters. To promote innovation, it encourages role flexibility, curiosity, small improvements, and the recognition of brilliant practices.
This article presents a co-designed model of brilliant care for older people, incorporating principles of connection and innovation that can be enacted through simple, resource-efficient practices.
For those who manage and deliver care for older people, the model encompasses simple, accessible, and cost-effective principles to: positively deviate from norms within the sector, offering care to older people; and to deliver brilliant care for older people. Furthermore, given that the model was co-designed with lived experience experts, managers, professionals, and clinicians, its principles are imbued with their experiential insights, which served to bring particular priorities to the fore.
The co-designers, who included lived experience experts, were invited to participate in workshops to co-design a model of brilliant care for older people, during which they discussed and critiqued the findings constructed from the data and co-designed the model.
Asynchronous telemedicine-based second opinions, using a purely document-based and written procedure, offer an opportunity to support patients in their medical decision-making, particularly those who cannot secure a timely face-to-face appointment nearby. The aim of the study is to investigate the benefits and challenges of asynchronous telemedicine in obtaining a second opinion and clarify for whom and under what conditions it is suitable.
We conducted a qualitative interview study as part of a larger mixed-methods study. The interviews were transcribed verbatim and analysed using qualitative content analysis.
Germany.
The study involved 40 patients (20 women and 20 men) who sought an asynchronous telemedicine-based second opinion via an online platform, predominantly for orthopaedic issues.
Asynchronous telemedicine-based second opinions offer advantages such as access to distant specialists, the ability to consult from home without waiting times, timeliness and a detailed, fact-based report. However, the absence of face-to-face contact presents challenges: it can feel impersonal, technical problems may arise, it can be difficult to articulate symptoms and medical history in writing, and spontaneous interaction or correction is limited.
Under certain conditions, telemedicine-based second opinions can be individualised without face-to-face interaction. Key factors for success include a clear medical question, a well-organised process with good customer support, comprehensive and individualised information, and patient readiness (technical skills, internet access and the ability to articulate symptoms in writing). Major challenges for the German healthcare system include overcoming a potential digital divide as certain patient groups may not be reached by digital services.
High-quality clinical practice guidelines and hospital standards on falls prevention and management now exist, yet their implementation into clinical practice is variable. Insights from consumers could help to guide the development of a process to improve the implementation of falls prevention and management, particularly in rehabilitation hospitals where fall rates are high.
A qualitative descriptive study will incorporate semistructured interviews and focus groups to explore the perspectives of hospital consumers on how hospital falls prevention evidence can best be implemented into rehabilitation practice. Thematic analysis of the data will be conducted in NVivo using a six-phase thematic coding process guided by Braun and Clarke. Evaluation and synthesis of the data will also follow the Consolidated Criteria for Reporting Qualitative Research checklist. Consideration of the results from the interviews and focus groups will provide insights into the views of people with lived experience of hospitalisation and falls. Thematic analysis will be supported by direct quotes for each key theme and will highlight how the themes relate to the study aims and the rehabilitation context.
The study was approved by La Trobe University Human Research Ethics Committee (HEC24526). The study will be published in a peer-reviewed journal, and findings will be presented at conferences, workshops and online events.
