Introduction

Teenage pregnancy remains a critical global health issue, particularly in low- and middle-income countries. The intergenerational transmission of teenage pregnancy underscores the need for targeted interventions. Existing research on intergenerational approaches is fragmented, with varying methodologies and outcomes. This scoping review seeks to address this gap by answering the following research questions: What are the available intergenerational interventions for teenage pregnancy, and what are the associated risks and protective factors for early and late teenage pregnancy?

Methods and analysis

This study does not involve primary data collection and therefore does not require ethical approval. The review will be conducted in five stages: identifying the research question; identifying relevant studies; study selection; charting the data; and collating, summarising and reporting the results. A comprehensive search of electronic databases, grey literature and relevant organisational websites will be conducted for literature published between 2014 and 2024. Data will be extracted using a standardised form and synthesised narratively. Stakeholder consultation will be conducted to refine findings and ensure relevance. The findings will be reported in accordance with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) extension for Scoping Reviews guidelines. The results will be presented through narrative synthesis, with tables and charts used to summarise key information.

Ethics and dissemination

As the review is based on publicly available data, ethical approval is not required. Ethical clearance will be sought for stakeholder consultations, if necessary. Findings will be disseminated through peer-reviewed publications, conferences, policy briefs and shared openly on the Open Science Framework (OSF). This protocol is registered in the OSF (https://doi.org/10.17605/OSF.IO/CM9WK).

Objectives

We aimed to evaluate the effect of projection mapping (PM) on the quality and safety of central venous catheter (CVC) insertion under real-time ultrasound guidance.

Design

Prospective, observational, simulation study.

Setting

This study was conducted at the Yokohama City University Medical Center (Yokohama, Japan). Volunteer residents were enrolled over 12 months from January to December 2023.

Participants and methods

12 rotating residents (postgraduation year (PGY) 1 and 2) and eight anaesthesia residents (PGY 3–5) placed the CVC in the internal jugular vein in a simulator under the real-time ultrasound guidance using the short-axis out-of-plane approach. The ultrasound image was provided either just caudad to the puncture site using the PM method or on the monitor of the ultrasound machine (conventional method) placed next to the simulator’s right shoulder. Each resident performed four punctures alternating between the PM and conventional methods, and the first method for each resident was chosen randomly. Eye-tracking analysis was also used to evaluate differences in gaze behaviour.

Primary and secondary outcome measures

The primary outcome was the procedure time defined as the time from the application of the ultrasound probe on the puncture field until successful puncture of the vein. The secondary outcomes were incidence of complications and eye-tracking analysis data.

Results

The time to complete the line placement was significantly shorter for the PM than for the conventional method (median (IQR) 22.5 (15.5–30.6) s vs 30.0 (20.4–95.4) s; p=0.02, Wilcoxon’s signed-rank test). The incidence of posterior vessel wall puncture was significantly lower in the PM method (0% vs 25%; p=0.02, McNemar’s test). Eye-tracking analysis revealed that the percentage of time spent gazing at the ultrasound image was higher in the PM than in the conventional method (61.6% (55.0–69.2) vs 45.7% (34.1–54.5); p

Conclusions

The PM method facilitates ultrasound-guided CVC placement while preventing excessive needle advancement in the inexperienced operators. This was accompanied by enhanced fixation of the participants’ line-of-sight on the ultrasound image.

The incidence of intraoperatively acquired pressure injuries in the park‐bench position was reduced by applying soft silicone multilayer foam dressings

Abstract

The Park-Bench Position (PBP) is associated with a high incidence rate of intraoperatively acquired pressure injuries (IAPIs). Preventive measures must be established to prevent the development of IAPIs. We investigated the risk factors for PBP by applying a soft silicone multilayered foam dressing (SMD) under core temperature management to prevent IAPIs. We conducted a prospective, single-centre, open-label observational study of patients undergoing elective neurosurgery operations using PBP in a university hospital in Japan. The incidence rate of IAPIs in this study was compared with that in our two previous studies, in which a film dressing was applied and core temperature management was not performed. IAPIs developed in 90 patients (6.7%); in the lateral thoracic region in five patients and the iliac crest region in one patient. The operative time (every 1 h: p = 0.0001, OR: odds ratio 3.62, 95% CI: confidence interval 1.73–11.42) was significantly associated with the incidence of IAPIs. In our two previous studies, the incidence rate of IAPIs was 11.0% and 24.1%, respectively, when film dressing was used. SMD may weaken the involvement of risk factors in IAPIs.
