Article Synopsis
  • - A new measure has been created to evaluate the Quality of Life (QoL) for young people aged 8-18 with advanced cancer, engaging young research partners in its development.
  • - The research followed a four-phase plan that included creating and testing the questionnaire for clarity, assessing its social validity, and refining it based on feedback from 12 young patients.
  • - The final versions of the questionnaires address key QoL domains and aim to meet the specific needs of young cancer patients and their families, receiving positive feedback during the evaluation process.

Article Synopsis
  • Preclinical data show that human muscle stem (hMuStem) cells have a strong ability to repair muscle injuries, but their survival after transplantation is limited.
  • This study explored using tunable calcium-alginate hydrogels to encapsulate hMuStem cells, improving their protection and potential for clinical applications.
  • The research found that the mechanical properties of these hydrogels vary based on gelation methods and concentrations, and encapsulated hMuStem cells retained their viability and functionality, suggesting a promising approach for muscle regeneration therapies.

Purpose: Exome sequencing (ES) and genome sequencing (GS) are diagnostic tests for rare genetic diseases. Studies report clinical utility of ES/GS. The goal of this systematic review is to establish how clinical utility is defined and measured in studies evaluating the impacts of ES/GS results for pediatric patients.

The management of pain in pediatrics is multimodal and includes non-pharmacologic and pharmacologic approaches. Opioids, and particularly morphine and hydromorphone, are frequently used to treat moderate-to-severe pain. The goals of this review are to describe the pharmacological characteristics of both drugs, to cover the latest evidence of their respective indications, and to promote their safe use in pediatrics.

Background: Opioids are often prescribed for acute pain to patients discharged from the emergency department (ED), but there is a paucity of data on their short-term use. The purpose of this study was to synthesize the evidence regarding the efficacy of prescribed opioids compared to nonopioid analgesics for acute pain relief in ED-discharged patients.

Methods: MEDLINE, EMBASE, CINAHL, PsycINFO, CENTRAL, and gray literature databases were searched from inception to January 2023.

Model systems are needed to provide controlled environment for the understanding of complex phenomena. Interaction between polysaccharides and proteins in dense medium are involved in numerous complex systems such as biomass conversion or plant use for food processing or biobased materials. In this work, cellulose nanocrystals (CNCs) were used to study proteins in a dense and organized cellulosic environment.

Osteoarthritis (OA) is an inflammatory joint disease that affects cartilage, subchondral bone, and joint tissues. Undifferentiated Mesenchymal Stromal Cells are a promising therapeutic option for OA due to their ability to release anti-inflammatory, immuno-modulatory, and pro-regenerative factors. They can be embedded in hydrogels to prevent their tissue engraftment and subsequent differentiation.

Article Synopsis
  • The study investigates how bystander CPR impacts survival rates and neurological outcomes for patients who experience out-of-hospital cardiac arrest (OHCA), considering the time it takes for emergency services to arrive.
  • Out of over 229,000 cases, researchers found that patients who received bystander CPR had significantly higher chances of surviving and achieving good neurological function compared to those who did not receive CPR.
  • However, longer emergency medical service (EMS) response times negatively affected survival and neurological outcomes, and bystander CPR did not lessen this negative effect from delayed response times.

Vaccines containing mRNA with the capacity to self-amplify represent an alternative to the mRNA vaccines that came to prominence during the COVID-19 pandemic. To gain further insights on the safety profile of self-amplifying mRNA- (SAM-) vaccines, this preclinical toxicology study in rats evaluated the effect of (i) the type of delivery system (lipid nanoparticle [LNP] vs cationic nano-emulsion [CNE]); (ii) antigen-encoding sequence (rabies glycoprotein G vs SARS-CoV-2 Spike); and (iii) RNA amplification. Further analyses also evaluated gene expression in peripheral blood after vaccination, and the biodistribution of vaccine RNA.

In neural networks that store information in their connection weights, there is a tradeoff between sensitivity and stability. Connections must be plastic to incorporate new information, but if they are too plastic, stored information can be corrupted. A potential solution is to allow plasticity only during epochs when task-specific information is rich, on the basis of a 'when-to-learn' signal.

The Drosophila brain contains about 50 distinct morphological types of dopamine neurons. Physiological studies of Drosophila dopamine neurons have been largely limited to one brain region, the mushroom body, where they are implicated in learning. By comparison, we know little about the physiology of other Drosophila dopamine neurons.

Background: Advanced childhood cancer, a condition with no available cancer-focused treatment options, greatly impacts Quality of Life (QoL). We need appropriate assessment strategies to select adapted treatment targets, improve care and optimize communication. Our first goal was to identify the domains of patients' QoL by combining for the first time the perspectives of patients and parents with previously collected reports in professionals.

Objective: Studies evaluating the prognostic value of the pulseless electrical activity (PEA) heart rate in out-of-hospital cardiac arrest (OHCA) patients have reported conflicting results. The objective of this study was to evaluate the association between the initial PEA heart rate and favorable clinical outcomes for OHCA patients.

Methods: The present post-hoc cohort study used the Resuscitation Outcomes Consortium Cardiac Epidemiologic Registry Version 3, which included OHCA patients in seven US and three Canadian sites from April 2011 to June 2015.

Objectives: The no-flow time (NFT) can help establish prognosis in out-of-hospital cardiac arrest (OHCA) patients. It is often used as a selection criterion for extracorporeal resuscitation. In patients with an unwitnessed OHCA for whom the NFT is unknown, the initial rhythm has been proposed to identify those more likely to have had a short NFT.

Background: Emergency departments (EDs) are operating at or above capacity, which has negative consequences on patients in terms of quality of care and morbi-mortality. Redirection strategies for low-acuity ED patients to primary care practices are usually based on subjective eligibility criteria that sometimes necessitate formal medical assessment. Literature investigating the effect of those interventions is equivocal.

Understanding the mechanism by which ion channel modulators act is critical for interpretation of their physiological effects and can provide insight into mechanisms of ion channel gating. The small molecule RY785 is a potent and selective inhibitor of Kv2 voltage-gated K+ channels that has a use-dependent onset of inhibition. Here, we investigate the mechanism of RY785 inhibition of rat Kv2.

Asthma is a heterogeneous disease, with multiple underlying inflammatory pathways and structural airway abnormalities that impact disease persistence and severity. Recent progress has been made in developing targeted asthma therapeutics, especially for subjects with eosinophilic asthma. However, there is an unmet need for new approaches to treat patients with severe and exacerbation-prone asthma, who contribute disproportionately to disease burden.
