Introduction

Vital signs such as heart rate (HR) and respiratory rate (RR), crucial for clinical assessment, are often challenging to measure in paediatric populations. Remote photoplethysmography (rPPG), a video-based measurement tool, has demonstrated accuracy in adults. The objective of this study is to compare HR and RR measurements obtained using rPPG with those from standard clinical monitoring in a paediatric population.

Methods and analysis

This is a monocentric, prospective study enrolling 600 paediatric participants. Each participant will have standard monitoring electrodes (ECG/impedance) placed on the chest while seated facing a camera for rPPG recording. Simultaneous HR and RR measurements will be recorded over periods of 30 and 60 s using both the standard monitor and the rPPG device. The intraclass correlation coefficient will be calculated to assess agreement between the rPPG and standard monitor measurements.

Ethics and dissemination

The study protocol has been approved by the French Agency for the Safety of Health Products (ANSM (Agence nationale de sécurité du médicament) registration no. IDRCB 2023-A02524-41) and by a French ethics committee (CPP Sud Méditerranée III at 29 August 2024, n°2024-A01324-43). The study’s findings will be published in peer-reviewed journals and disseminated at national and international conferences and through press releases.

Introduction

Each year, physical traumas affect over one billion people worldwide, generating a substantial burden in terms of mortality, disability and productivity loss. The period following hospital discharge, encompassing the transition to home, short-term stays in rehabilitation facilities, as well as outpatient and community-based follow-up care, represents a critical phase in the recovery process for trauma injury patients. Yet, this phase remains poorly documented. We aim to (1) Map data on assessment strategies for various outcomes among trauma survivors after hospital discharge, including the tools used and how they are administered, as well as the resources required, and the barriers and facilitators to their implementation, and (2) Compare the feasibility of implementing the assessment strategies while considering response rates, resource use, costs and sustainability.

Methods and analysis

We will conduct a scoping review using the Joanna Briggs Institute methodology. We will search MEDLINE, Embase, CINAHL, Scopus and PsycINFO for studies published since 1990 to reflect the evolution of contemporary follow-up practices, including the emergence of Patient-Reported Outcome Measures and digital tools. There will be no language restrictions. We will consider all studies involving trauma survivors, focusing on the evaluation of postdischarge health outcomes. Two independent reviewers will screen studies and extract data on population characteristics, assessment strategies and feasibility. Results will be analysed thematically and presented narratively. We will present counts and percentages for each assessment strategy, along with its characteristics and associated barriers and facilitators. Subgroup analyses will also be conducted based on clinical and social determinants and contextual factors.

Ethics and dissemination

Ethics approval is not required for this review. The results of this scoping review will be shared through publication in a peer-reviewed journal, conference presentations and our network of knowledge users.

Randomised controlled trial of laparoscopic primary crural repair versus additional circular bioabsorbable mesh reinforcement in hiatal hernia (PRIME-II trial): an RCT protocol

Por: de Haas · J. W. A. · Geerts · J. H. · de Boer · E. · Brohet · R. M. · Hazebroek · E. J. · Wassenaar · E. B. · Nieuwenhuijs · V. B. — Enero 28th 2026 at 14:51
Introduction

Laparoscopic hiatal hernia (HH) repair is associated with a high recurrence rate. Repair reinforced with mesh lowers short-term recurrence but can cause dysphagia and visceral erosion. Results of the PRIME trial, in which non-absorbable mesh reinforcement of the posterior crural repair was investigated, showed equal recurrence compared with primary suture repair after 6 months. This study investigates the use of circular absorbable mesh reinforcement in primary HH repair.

Methods and analysis

Prospective double-blinded randomised controlled superiority trial comparing two laparoscopic procedures for HH repair (110 vs 110). Adult patients with proven HH Skinner types II–IV (defined by preoperative CT scan) are included. Patients are randomised to undergo a laparoscopic primary crural repair with sutures alone or suture repair augmented with biosynthetic absorbable, circular mesh at the hiatus. Radiologic integrity of the hiatal repair 1 year after surgery is the main endpoint. Secondary objectives are clinical recurrence of the hernia, development of postoperative reflux disease, postoperative side effects and satisfaction with surgical outcome. Outcome assessors are blinded to allocation. Data are collected at baseline, and follow-up includes interviews and digital questionnaires at 3, 12, 24, 36, 48 and 60 months, as well as CT scan at 12 and 60 months. All patients randomised will be analysed according to the intention-to-treat principle.

Ethics and dissemination

Ethics approval has been obtained by the local ethics committee at Isala, Zwolle, the Netherlands (Medical Ethics Review Committee (METc) Isala, study number: 190516). METc Isala is no longer active; all duties have been taken over by METc of the University Medical Center Groningen. The trial’s results will be submitted to a peer-reviewed international journal as well as (inter)national conferences.

Placebo and nocebo in clinical practice: An online cross-sectional survey of healthcare professionals from European countries on views, practices and training needs

by Mary O’Keeffe, Nathan Skidmore, Arianna Bagnis, Przemysław Bąbel, Elżbieta A. Bajcar, Alessandra De Palma, Andrea W.M. Evers, Eveliina Glogan, Julia W. Haas, Stefanie H. Meeuwis, Marek Oleszczyk, Antonio Portolés, Johan W.S. Vlaeyen, Katia Mattarozzi, on behalf of PANACEA Consortium

Background

Placebo and nocebo effects significantly influence health outcomes, yet healthcare professionals receive limited training and guidance on their mechanisms and clinical application, creating a gap in education and practical understanding. Conducted within the European PANACEA Consortium, this study evaluated healthcare professionals’ knowledge, attitudes, and practices regarding placebo and nocebo effects, and assessed their needs in further education.

Methods

An online cross-sectional survey among a European multi-country convenience sample of healthcare professionals collected data assessing participants’ knowledge, perceptions, and experiences regarding placebo and nocebo effects; their application and ethical considerations in clinical practice; and investigated educational needs and interest in further training. Quantitative data were analyzed using descriptive statistics, and thematic analysis was applied to the free-text responses.

Results

Amongst 807 participants, 71.7% reported taking advantage of placebo effects in their practice, and over half of participants (55.8%) observing nocebo effects. Participants reported feeling somewhat confident (53.3%) in harnessing placebo effects with 47.5% feeling confident in preventing nocebo effects. The majority of respondents had not received formal training on placebo and nocebo effects, with most expressing an interest in further training in areas such as healthcare education, emphasizing communication skills to enhance placebo effects, and knowledge to recognize and reduce nocebo effects.

Conclusions

There is a significant need for more comprehensive training on placebo and nocebo effects, particularly in early health professional education. These findings informed the development of educational resources and best practice recommendations developed as part of the outcomes from the PANACEA Consortium, improving the understanding and application of these effects among healthcare professionals across Europe.

Treatment of bulbar urethral strictures with Optilume drug-coated balloons in a previously untreated population (FIRST-CARE): protocol for a single-blind multicentre randomised controlled trial

Por: Mahdi · M. B. · Haase · R. N. · Sander · L. · Tuckus · G. · Liltorp · D. L. · Jorgensen · L. · Graugaard-Jensen · C. H. · Weinreich · H. · Pennisi · C. P. · Nielsen · T. K. — Enero 8th 2026 at 13:18
Introduction

Minimally invasive endoscopic procedures constitute the cornerstone of first-line treatment for bulbar urethral strictures, although their long-term effectiveness is limited by high recurrence rates. The Optilume drug-coated balloon (DCB) is a novel intervention combining mechanical dilation with localised delivery of paclitaxel to reduce recurrence by inhibiting scar tissue formation. While its efficacy has been demonstrated in patients with recurrent strictures, its potential as a first-line option in treatment-naïve patients remains unexplored. The FIRST-CARE trial aims to assess the efficacy and safety of Optilume DCB compared with standard endoscopic treatment in treatment-naïve patients with bulbar urethral strictures.

Methods and analysis

Design: Two-arm, randomised, single-blind (participant), investigator-initiated, parallel-group, multicentre clinical trial. Patients: The study will enrol 140 adult male patients with treatment-naïve, single bulbar urethral strictures ≤3 cm in length. Interventions: All patients will undergo the assigned procedure under general anaesthesia with 1.5 g intravenous cefuroxime. Optilume group patients will receive ≥5 min balloon dilation with localised paclitaxel delivery. The control group will receive standard endoscopic treatment (eg, direct visual internal urethrotomy, laser or dilatation). In both groups, a 12–14 French Foley catheter will be left in place for 3–5 days. Primary outcome: Freedom from repeat intervention within 12 months of follow-up. Primary analysis: Time-to-event will be defined from the date of intervention to the date a repeat intervention is decided (indicated and planned) due to confirmed recurrence, with censoring at 12 months. Groups will be compared using Kaplan-Meier survival analysis and the log-rank test. Cox regression and modified Poisson regression will be used to estimate HRs and relative risks.

Ethics and dissemination

The trial is approved by the Danish National Committee on Health Research Ethics (2401370) and will be conducted in accordance with the Declaration of Helsinki and principles of Good Clinical Practice. In line with national guidelines, all eligible patients are counselled regarding available treatment options prior to enrolment. Results will be disseminated via peer-reviewed publications and scientific presentations.

Content validity, practicality and testing of the reliability of various tools for the detection and screening of delirium in residents with dementia in German nursing homes: a study protocol

Por: Seiters · J. C. · Molitor · V. · Morandi · A. · Zieschang · T. · Dichter · M. N. · Haastert · B. · Erdmann · M. · Hoffmann · F. · Palm · R. — Diciembre 25th 2025 at 05:45
Introduction

Although individuals with dementia who reside in nursing homes are particularly susceptible to developing delirium, this condition is rarely recognised in these settings. Detection of delirium requires validated and reliable tools for this setting that can be applied by nursing staff. The primary objective of the study is to assess the comprehensibility, practicality and inter-rater reliability of two delirium detection tools (4 A’s test (4AT) and 4-item delirium superimposed on dementia (4-DSD)) and one tool for assessing both the diagnosis and severity of delirium (Delirium Rating Scale-Revised-98 (DRS-R-98)) in people with dementia who reside in nursing homes when used by nurses.

Methods and analysis

The comprehensibility and practicality of the German versions of the 4AT, 4-DSD and DRS-R-98 will be evaluated using cognitive interviews in accordance with the consensus-based standards for the selection of health measurement instruments framework. On the basis of the results of the cognitive interviews, a manual for each of the three tools will be developed and finalised by an expert panel. Finally, the inter-rater reliability and measurement error of the three tools will be determined using the manuals. For this purpose, a total of 70 residents from six nursing homes will be assessed by at least two nurses. The data analysis will include descriptive statistics and inter-rater reliability assessment for individual items (kappa value) and total scores (Intraclass correlation coefficients).

Ethics and dissemination

This study will assess the comprehensibility, practicality and inter-rater reliability of the 4AT, 4-DSD and DRS-R-98 for use in residents with dementia in nursing homes. The project was approved by the medical ethics committee of the University of Oldenburg (reference number: 2025-093).

Trial registration number

The inter-rater reliability study was registered in the German Clinical Trials Register. Registration number: DRKS00037458 (https://www.drks.de/search/de/trial/DRKS00037458/details).

Introduction

The currently available immunotherapies have failed to meet expectations in inducing durable responses in patients with advanced epithelial ovarian cancer (EOC). The low number of somatic missense mutations in EOC necessitates highly potent neoantigen-directed approaches. To this end, we have developed a novel dendritic cell (DC) product that consists of a specialised cross-presenting subset of DC, conventional DC type 1 (cDC1).

Methods and analysis

We will conduct the NEODOC study, an investigator-initiated first-in-human phase I/II trial. This study will assess the immunogenicity, safety and feasibility of a cDC1-based, autologous tumour lysate-loaded, DC product. 10 patients with previously untreated advanced EOC (stage IIIb-c, IVa or stage IVb if only supradiaphragmatic or inguinal lymph nodes

Adherence to guidelines on quality neonatal resuscitation practices among healthcare professionals in Ghana: an observational study

Por: Salia · S. M. · Kaba · R. A. · de Haas · B. · Stekelenburg · J. — Agosto 19th 2025 at 15:52
Aims and objectives

The study evaluated healthcare professionals’ adherence to guidelines on quality neonatal resuscitation practices in Ghana.

Design

This study employed an observational design. A validated observational checklist for neonatal resuscitation was used to assess the adherence to quality neonatal resuscitation guidelines among healthcare professionals.

Setting

The study was conducted among healthcare professionals in six healthcare facilities, consisting of five government-owned healthcare facilities and a private non-profit health facility across the northern, middle and coastal belts of Ghana.

Participants

The study participants were 75 healthcare professionals across the six sampled healthcare facilities.

Outcome measures

Outcome measures of interest are: initial preparation prior to resuscitation; stimulation and airway maintenance; positive pressure ventilation; coordinated positive pressure ventilation with chest compression and postresuscitation infection prevention and control measures.

Results

The results revealed that 53% of the healthcare professionals demonstrated good (scored 80%–100%) adherence to guidelines on quality neonatal resuscitation practices; the remaining scored moderate 36% (scored 50%–79%) and 11% (scored 0%–49%) poor adherence. Binary logistic regression analysis revealed that increased staffing levels and a bachelor’s degree or higher were positively associated with the performance of positive pressure ventilation (adjusted OR (aOR) 19.3 (95% CI 2.430799, 152.8657), p=0.005) and (aOR 9.9 (95% CI 1.070278, 92.38303), p=0.043), respectively. Furthermore, professional nurses and medical practitioners were more likely to adhere to coordinated positive pressure ventilation with chest compressions than auxiliary nursing staff (aOR 13.2 (95% CI 1.917858, 92.61999), p=0.009) and (aOR 15.7 (95% CI 1.227859, 200.1105), p=0.034).

Conclusion

The results showed that 53% of healthcare professionals demonstrated good adherence for neonatal resuscitation practices. Addressing the identified gaps and inequalities in neonatal resuscitation practice will improve healthcare professionals’ knowledge and skills in neonatal resuscitation, which ultimately helps to reduce neonatal deaths among babies in Ghana.

Randomized Trial of Group Postpartum Care Model Improves Knowledge and Clinical Outcomes

Por: Adams, Yenupini Joyce · Agbenyo, John Stephen · Lau, Elizabeth · Young, Jessica · Haas, David — Febrero 13th 2025 at 01:00
imageBackground In sub-Saharan Africa, the risk of obstetric complications remains high throughout the postpartum period. Objective We developed and tested a novel, integrated model of group postpartum care titled Focused-Postpartum Care (Focused-PPC) to improve outcomes. In this paper, we report clinical outcomes of participants in the intervention arm and differences in knowledge of postbirth warning signs among those in the intervention and control arms. Methods Focused-PPC encompassed recommended clinical assessments, targeted education, and peer support up to 1 year after birth. Focused-PPC was implemented as a parallel randomized controlled trial involving 192 postpartum women across four health centers in Tamale, Ghana, from February 2022 to August 2023. Eligible participants 18 years or older with a live birth were randomly assigned to either the Focused-PPC intervention arm or the control arm at a 1:1 allocation and were not blinded to their allocation. At each health center, 48 participants were allocated to either an intervention or control arm. Focused-PPC groups in the intervention arm consisted of eight participants per group. Participants in the intervention arm received the Focused-PPC integrated group model of care. Participants in the control arm received the standard of postnatal care already administered at each health center. Results Baseline analysis included 96 participants from the control arm and 91 participants from the intervention arm. We found that vital signs and clinical outcomes were relatively stable; however, incidences of hypertension substantially decreased among participants in the intervention arm. By 3 months postbirth, most participants in the intervention arm were able to identify all postbirth warning signs and retain this knowledge compared to the control arm. Those in the intervention arm were also knowledgeable of more warning signs at each time point compared to the control arm. Discussion An integrated, evidence-based approach to postpartum care, such as Focused-PPC, has potential to increase knowledge and improve clinical outcomes among mothers in Ghana.

A Systematic Review of Features Forecasting Patient Arrival Numbers

Por: Förstel, Markus · Haas, Oliver · Förstel, Stefan · Maier, Andreas · Rothgang, Eva — Octubre 21st 2024 at 02:00
imageAdequate nurse staffing is crucial for quality healthcare, necessitating accurate predictions of patient arrival rates. These forecasts can be determined using supervised machine learning methods. Optimization of machine learning methods is largely about minimizing the prediction error. Existing models primarily utilize data such as historical patient visits, seasonal trends, holidays, and calendars. However, it is unclear what other features reduce the prediction error. Our systematic literature review identifies studies that use supervised machine learning to predict patient arrival numbers using nontemporal features, which are features not based on time or dates. We scrutinized 26 284 studies, eventually focusing on 27 relevant ones. These studies highlight three main feature groups: weather data, internet search and usage data, and data on (social) interaction of groups. Internet data and social interaction data appear particularly promising, with some studies reporting reduced errors by up to 33%. Although weather data are frequently used, its utility is less clear. Other potential data sources, including smartphone and social media data, remain largely unexplored. One reason for this might be potential data privacy challenges. In summary, although patient arrival prediction has become more important in recent years, there are still many questions and opportunities for future research on the features used in this area.
