Photobiomodulation (PBM) has shown promising effects in managing postoperative pain following conventional periapical surgery, although current evidence remains limited. This study aims to assess the effect of PBM on postoperative pain 24 hours after periapical surgery.

A randomised, controlled, double-blind trial will include 34 patients undergoing periapical surgery in the maxillary region, randomly assigned to an experimental group (n=17) or control group (n=17). The experimental group will receive PBM (GaAlAs diode laser, 808 nm, 100 mW, 4 J/cm², applied at five vestibular points) and placebo ibuprofen immediately and 24 hours postoperatively. The control group will receive simulated PBM and active ibuprofen. The primary outcome is postoperative pain assessed by the visual analogue scale at 24 hours. Secondary outcomes include pain at the seventh day, paracetamol intake, oedema, ecchymosis, soft tissue status and temperature at 24 hours and 7 days. Radiographic evaluation of healing will be performed at 1 and 3 months. Statistical analysis will be conducted based on data distribution, using repeated measures ANOVA (Analysis of Variance) or non-parametric equivalents for longitudinal outcomes, and appropriate tests for categorical variables. Significance will be set at p

The study was approved by the Human Research Ethics Committee of Universidad Católica del Uruguay (process no. 220914). Results will be disseminated to participants, healthcare professionals, the public and scientific communities.

Electronic health register's (eRegisters) use have recently gained popularity in Africa. eRegisters are used to capture real-time patient information on several encounters with a healthcare provider. Given poor maternal and child health outcomes in Lesotho, eRegisters provide a promising innovative means of enhancing health outcomes, especially those related to midwifery. eRegisters capture maternal and newborn care services provided at healthcare facilities. Such data are important for informing evidence-based midwifery practice. Lesotho, a landlocked, sub-Saharan African country, piloted use of an eRegister in 2018. However, factors promoting eRegister and data use have not been fully documented. Therefore, this study explored factors promoting eRegister and data use for midwifery practice in Lesotho.

The study used a descriptive qualitative approach with interviews and focus group discussions used to collect data. Descriptive content analysis as outlined by Erlingsson and Brysiewicz (2017) was followed during data analysis.

The study was conducted at three of the eRegister piloting facilities in Lesotho to examine eRegister implementation across different levels of care. Data collection occurred between December 2023 and March 2024.

Purposive sampling was used to recruit healthcare workers across the three facilities. Participants were selected to capture the range of relevant roles and experience with eRegister across each facility, and 7, 6 and 5 participants were recruited.

Five categories emerged as factors promoting eRegister and data use: system readiness, organisational environment, data value and utility in practice, human resource competency and digital literacy and governance and stakeholder engagement.

This study identified critical factors that promote the use of the eRegister and data in Lesotho. The findings suggest that while external funding and partner responsiveness have been pivotal in sustaining eRegister operations, long-term sustainability will require stronger national ownership, including domestic investment in infrastructure, technical support and digital health governance. Future studies should explore the effect of eRegister use on clinical outcomes and examine strategies for scaling up digital health interventions in resource-limited settings.

The development of the target trial emulation (TTE) methodology has enhanced the conduct of non-randomised studies. By leveraging readily available routinely collected data, TTEs offer opportunities for complementing randomised controlled trials (RCTs), providing more precise estimates and improving the external validity of RCTs. To explore this potential, we selected a successfully completed RCT as a case study. In the FIRST-line support for Assistance in Breathing in Children (FIRST-ABC) step-up RCT, high flow nasal cannula (HFNC) was found to be non-inferior to continuous positive airway pressure (CPAP) in terms of time to liberation from respiratory support in the paediatric critical care setting. We will emulate the FIRST-ABC step-up trial using routinely collected data from the Paediatric Intensive Care Audit Network (PICANet) database.

This is a protocol for a TTE that will use longitudinally collected data from the PICANet database. The study aims to emulate the FIRST-ABC step-up RCT using an observational study design in a frequentist framework. We will benchmark the results against the published trial. The study will apply a new-user design by selecting children admitted to paediatric intensive care units that started HFNC or non-invasive ventilatory support (as a surrogate for CPAP). The eligibility criteria and selected outcomes will reflect those of FIRST-ABC within the constraints of the available routinely collected data. We will use advanced quantitative doubly robust methods to minimise the impact of confounding by indication and allow for heterogeneity according to child characteristics. The analysis will be repeated using a Bayesian approach for follow-up research.

The research received ethics approval from the London School of Hygiene & Tropical Medicine Research Ethics Committee. This study will expand the findings from the FIRST-ABC step-up RCT, providing additional insight from a large representative sample using real-world data. The frequentist and Bayesian approaches will enable a discussion about the advantages and drawbacks of the two strategies. The results will be disseminated to the research and clinical community and made accessible to the public. In addition, the study results will be used in future research, which aims to supplement RCTs with additional evidence from a TTE.

This scoping review aims to assess low-cost simulation methods used in nursing education, evaluating how they balance educational effectiveness with budget constraints.

Scoping review conducted in accordance with Arksey and O’Malley’s methodological framework and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews reporting guidelines.

PubMed, Embase and CINAHL were systematically searched for relevant studies published between January 2000 and October 2023.

We included peer-reviewed primary studies involving nurses or nursing students, focused on the use of low-cost simulation in any healthcare setting. Studies had to describe the simulation strategy and its educational application.

Two reviewers independently screened titles, abstracts and full texts and extracted data using a standardised form. Findings were synthesised narratively and categorised by type of simulation, educational context and competencies addressed.

Out of 3332 records, 39 studies met the inclusion criteria. The reviewed studies covered various clinical areas, including critical care, emergency, neonatal, paediatric and obstetric nursing, as well as transversal competencies such as communication and clinical reasoning. Low-cost methods included task trainers, mannequins, computer-based tools, hybrid models and serious games. Only 38% of studies reported detailed cost information.

Low-cost simulation offers promising opportunities in nursing education but suffers from inconsistent cost reporting and a lack of standardisation. Further research is needed to evaluate its long-term effectiveness and support broader implementation.

VALTIVE1 is a multi-centre, single-arm, non-interventional biomarker study for patients with advanced ovarian cancer. Plasma samples (Tie2 concentration) are collected to detect vascular control in tumours during standard treatment with chemotherapy and bevacizumab. This qualitative study embedded in VALTIVE1 aimed to assess the acceptability and feasibility of a potential VALTIVE2 trial. It explored the participants’ perceptions of the study and treatments and how they might feel if bevacizumab were discontinued based on the results from the biomarker test.

This qualitative study used semi-structured telephone interviews, which were analysed using deductive and inductive thematic analysis.

Cancer treatment sites in the UK.

Participants recruited to VALTIVE1 were invited to take part in qualitative interviews. 11 female participants took part from four clinical sites.

Participants reported that they experienced side effects attributed to bevacizumab, including stiffness, pain, fatigue, nose bleeds and muscle aches. Participants felt that combining chemotherapy and bevacizumab may have increased the severity of the side effects they experienced. Most participants felt that it was acceptable, if not preferable, to be allocated to a group in a future VALTIVE2 study where bevacizumab may be discontinued according to the results from the biomarker test. A clear preference of participants was to be informed of the biomarker test results, health status and treatment side effects.

A future trial should consider ensuring all participants have access to test results, as participants indicated a preference to know whether bevacizumab was working and to discontinue bevacizumab if it had not prevented tumour growth based on the biomarker results. Comprehensive and ongoing information and support regarding treatment side effects should be provided to all participants throughout their cancer pathways and trials.
