Article Abstract

The purpose of this study is to assess the clinical impact of next-generation sequencing (NGS), as an increasingly available and advantageous tool, for glioblastoma patients. Adult patients aged less than 65, and surgically treated for glioblastoma between 2010-2021, were included. Tumor samples were analyzed with NGS using the Oncomine Comprehensive v3 (OCA) panel and Ion Reporter Genexus v5.9.1 (Thermo Fisher Scientific). Thirty-two patients were included, with a median age of 47.7 years and a median overall survival of 25 months. Identification of mutations by NGS resulted in a change in diagnosis in two cases. In all patients but one, at least one genetic alteration was detected (median of three per patient), most commonly EGFR amplification. In 93.7% of patients, biomarkers that make them potentially eligible for a clinical trial were found. No survival differences were seen regarding genetic alterations, although a trend towards better survival for those patients without CDK4 mutation was observed ( = 0.088). The use of NGS provides useful information for diagnosis, especially in young patients, and it will probably become valuable for clinical decision-making as more therapeutic targets and treatments emerge. For the moment, it is crucial for scientific progress to happen.

Background: Children in low- and middle-income countries face obstacles to optimal language and cognitive development due to a variety of factors related to adverse socioeconomic conditions. One of these factors is compromised caregiver-child interactions and associated pressures on parenting. Early development interventions, such as dialogic book-sharing (DBS), address this variable, with evidence from both high-income countries and urban areas of low- and middle-income countries showing that such interventions enhance caregiver-child interaction and the associated benefits for child cognitive and socioemotional development.

Purpose Of Review: Diagnostic stewardship (DS) aims to optimise the use of laboratory testing to improve patient care while reducing unnecessary tests. This review examines recent evidence on DS interventions to optimise the use of resources, focusing on three key areas: reducing unnecessary testing, maximising the impact of existing tests, and avoiding the overdiagnosis of hospital-acquired infections.

Recent Findings: Multiple interventions have demonstrated effectiveness in reducing unnecessary blood and urine culture testing, including clinical decision support tools, education programs, and multidisciplinary approaches.

Importance: For the first time in nearly 2 decades, the US infant mortality rate has increased, coinciding with a rise in overdose-related deaths as a leading cause of pregnancy-associated mortality in some states. Prematurity and low birth weight-often linked to opioid use in pregnancy-are major contributors.

Objective: To assess the health and economic impact of perinatal opioid use disorder (OUD) treatment on maternal and postpartum health, infant health in the first year of life, and infant long-term health.

Since the first decentralized clinical trial (DCT) was conducted in 2011, there has been an increased usage of DCT due to its benefits of patient-centricity and generalizability of findings. This trend was further expedited by the global COVID-19 pandemic. We identified 23 case studies across various therapeutic areas and grouped them into different categories according to their purposes-by necessity, for operational benefits, to address unique research questions, to validate innovative digital endpoints, or to validate decentralization as a clinical research platform.

Importance: The cost-effectiveness of adding early in-bed cycling to usual physiotherapy among adults receiving mechanical ventilation in the intensive care unit (ICU) compared with usual physiotherapy alone is unknown.

Objective: To evaluate the cost-effectiveness of in-bed cycling plus usual physiotherapy compared with usual therapy alone in the Critical Care Cycling to Improve Lower Extremity Strength (CYCLE) randomized clinical trial.

Design, Setting, And Participants: This trial-based economic evaluation with a 90-day time horizon compared early cycling plus usual physiotherapy vs usual physiotherapy alone from a societal perspective.
