Potential applications of 7 Tesla magnetic resonance imaging in paediatric neuroimaging:Feasibility and challenges

The integration of 7 Tesla magnetic resonance imaging(7 T MRI)in adult patients has marked a revolutionary stride in radiology.In this article we explore the feasibility of 7 T MRI in paediatric practice,emphasizing its feasibility,applications,challenges,and safety considerations.The heightened resolution and tissue contrast of 7 T MRI offer unprecedented diagnostic accuracy,particularly in neuroimaging.Applications range from neuro-oncology to neonatal brain imaging,showcasing its efficacy in detecting subtle structural abnormalities and providing enhanced insights into neurological conditions.Despite the promise,challenges such as high cost,discomfort,and safety concerns necessitate careful consideration.Research suggests that,with precautions,7 T MRI is feasible in paediatrics,yet ongoing studies and safety assessments are imperative.

Extension of Chemoprevention of Seasonal Malaria to Five Cycles and to Children from the Age of 6 to 9 Years in Africa: Analysis of Its Acceptability, Feasibility, Cost and Impact A Systematic Review

Introduction: Seasonal Malaria Chemoprevention (SMC) aims at preventing malaria in children during the high transmission season. It has been recommended by the WHO since 2013 for children from the age of 3-59 months. However, despite the impact of this intervention, a peak in the prevalence and incidence of malaria is observed in children from the age of 5-9 years. The aim of this study is to determine from the current literature the feasibility, impact and cost-effectiveness of extending SMC to five cycles and to older children. Methods: A litterature search of PubMed/Medline, NCBI and Google scholar identified 1333 articles. After reading the titles and abstracts by two authors, 24 articles were selected and submitted for full reading. Random control studies on the extension of SMC, malaria, feasibility of SMC, impact of SMC and cost-effectiveness of SMC were selected. A total of 16 articles were included for the qualitative synthesis after excluding 8 studies. Results: Following the summary of the evidence, we conclude that the extension is feasible but will be confronted with the unavailability of older children. The intervention period coincides with field work. SMC is effective in reducing the prevalence and incidence of malaria and the parasite density in children. The financial cost of administering SMC is lower than that of treating a child suffering from malaria. Conclusion: After analysing the information, it was found that the majority of the African population supports the extension of the SMC to the number of cycles and the age group in order to alleviate the high mortality and morbidity rates among children due to malaria.

A pilot clinical study to evaluate feasibility of using single patient classifier as a prognostic test in stage Ⅱ-Ⅲ gastric cancer patients

Objective:Precision medicine approaches emphasize the importance of reliable prognostic tools for guiding individualized therapy decisions.In this study,we evaluated the clinical feasibility of the single patient classifier(SPC)test,a new clinical-grade prognostic assay,in stageⅡ-Ⅲgastric cancer patients.Methods:A prospective multicenter study was conducted,involving 237 patients who underwent gastrectomy between September 2019 and August 2020 across nine hospitals.The SPC test was employed to stratify patients into risk groups,and its feasibility and performance were evaluated.The primary endpoint was the proportion of the cases in which the test results were timely delivered before selecting postoperative treatment.Furthermore,3-year disease-free survivals of risk groups were analyzed.Results:The SPC test met the primary endpoint criteria.The 99.5%of SPC tests were timely delivered to hospitals before the postoperative treatment started.In a clinical setting,the median time from the specimen transfer to laboratory to the result delivery to hospital was 4 d.Furthermore,3-year disease-free survivals were significantly different between risk groups classified with SPC tests.Conclusions:This study highlights the SPC test's feasibility in offering crucial information timely delivered for making informed decisions regarding postoperative treatment strategies.It also provides evidence to support the implementation of a future prospective clinical trial aimed at evaluating the clinical utility of the SPC test in guiding personalized treatment decisions for gastric cancer patients.

Safety and feasibility of enhanced recovery after surgery-based management model for ambulatory pediatric surgical procedures

BACKGROUND There is still some room for optimizing ambulatory pediatric surgical procedures,and the preoperative and postoperative management quality for pediatric patients needs to be improved.AIM To discuss the safety and feasibility of the enhanced recovery after surgery(ERAS)-based management model for ambulatory pediatric surgical procedures.METHODS We selected 320 pediatric patients undergoing ambulatory surgery from June 2023 to January 2024 at The First People’s Hospital of Liangshan Yi Autonomous Prefecture.Of these,220 received ERAS-based management(research group)and 100 received routine management(control group).General information,postoperative ambulation activities,surgical outcomes(operation time,postoperative gastro-intestinal ventilation time,and hospital stay),postoperative pain visual analogue scale,postoperative complications(incision infection,abdominal distension,fever,nausea,and vomiting),and family satisfaction were compared.RESULTS The general information of the research group(sex,age,disease type,single parent,family history,etc.)was comparable to that of the control group(P>0.05),but the rate of postoperative(2 h,4 h,and 6 h after surgery)ambulation activities was statistically higher(P<0.01),and operation time,postoperative gastrointestinal ventilation time,and hospital stay were markedly shorter(P<0.05).The research group had lower visual analogue scale scores(P<0.01)at 12 h and 24 h after surgery and a lower incidence of total postoperative complications than the control group(P=0.001).The research group had higher family satisfaction than the control group(P=0.007).CONCLUSION The ERAS-based management model was safe and feasible in ambulatory pediatric surgical procedures and worthy of clinical promotion.

Development of an adolescent coping model in seasonal flood-prone areas:a qualitative feasibility study

Objective:The aim is to develop and verify the feasibility of an adolescent coping model in seasonal flood-prone areas.This coping model supports mental health nurses'practical application to adolescents in flood-prone areas.Methods:We developed the adolescent coping model based on the processes established in three integrated theories:self-care management for vulnerable populations,coping approaches,and coping with disaster.We conducted semi-structured interviews with 15 participants to explore their perspectives and experiences with flood disasters.We used purposeful sampling for maximum diversity.Data were collected through face-to-face,in-depth interviews.Data were transcribed verbatim,followed by qualitative content analysis.The coping model of adolescents in flood-prone areas was analyzed qualitatively and inductively from the viewpoint of acceptability.Results:The following five categories were identified:(1)coping process post-disaster;(2)coping approach;(3)community power;(4)vulnerability;and(5)self-potential.These domains formed a model for coping model adolescents in seasonal flood-prone areas.Accordingly,our findings showed that the model could be practical for mental health community nursing.Conclusions:Mental health nurses can use the coping model for disaster mental health nursing in adolescents in flood-prone areas.The application of this model will help adolescents increase self-efficacy.
