Patterns of skeletal trauma resulting from motor vehicle collisions: a scoping literature review.

As a leading cause of fatality, motor vehicle collisions comprise a significant proportion of medico-legal cases worldwide. During death investigations into such events, forensic practitioners may be asked to make inferences about the relationship between traumatic injuries and the circumstances of the collision. These interpretations require a thorough understanding of the hard and soft tissue blunt force trauma that results from vehicle collisions.

Association of Early Epinephrine with Hemodynamics and Outcome in Pediatric In-Hospital Cardiac Arrest: A Secondary Analysis of a Multicenter, Cluster-randomized Clinical Trial Intensive Care Unit Resuscitation (ICU-RESUS).

Delayed (>5 minutes) epinephrine during pediatric in-hospital cardiac arrest (IHCA) is associated with worse outcomes. Epinephrine is nearly always given earlier, limiting 5 minutes as a quality target. To assess early epinephrine administration (⩽2 minutes) on outcomes and hemodynamics during cardiopulmonary resuscitation (CPR) in pediatric IHCA from pulseless, nonshockable rhythms.

Synthesis of Adenine Nucleosides with a Reactive (-Iodovinyl)sulfone or (-Keto)sulfone Group at the C2 Position and Their Polymerase-Catalyzed Incorporation into DNA.

Iodosulfonylation of an ethynyl group at the C2 position of 2'-deoxyadenosine or adenosine with TsI provides ()-2-(-iodovinyl)sulfones. The latter undergo nucleophilic substitution with amines via an addition-elimination to give -sulfonylvinylamines (enamines). Acid-catalyzed hydrolysis of the -sulfonylvinylamines provides 2-(-keto)sulfones, mechanistically different probes that react with alkyl halides, resulting in α-alkylation.

An Update on the Role of Lymphatic Function in Skin Inflammatory Disorders: A Scoping Review.

The lymphatic system is essential in maintaining skin health through coordinated immunological actions. This review explores the relationship between lymphatic function and skin health, as well as the impact of lymphatic dysfunction in the development and progression of inflammatory skin disorders. A systemic search was conducted in the Web of Science, Embase, and Ovid MEDLINE databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines.

Investigating skeletal fracture patterns in truck occupants involved in fatal motor vehicle incidents.

Globally, thousands of truck occupants die annually from motor vehicle incidents. During medico-legal investigations of such incidents, forensic practitioners are required to undertake thorough examinations of the injuries present. Despite this, very few studies assessing skeletal fractures in particular, in deceased truck occupants are currently available in the literature for practitioners.

Cardiopulmonary resuscitation employing only abdominal compressions in infants after cardiac surgery: A secondary sub-analysis of the ICU-RESUS study.

Importance: Patients with underlying cardiac disease form a considerable proportion of pediatric patients who experience in-hospital cardiac arrest. In pediatric patients after cardiac surgery, CPR with abdominal compressions alone (AC-CPR) may provide an alternative to standard chest compression CPR (S-CPR) with additional procedural and physiologic advantages.

Objective: Quantitatively describe hemodynamics during cardiopulmonary resuscitation (CPR) and outcomes of infants who received only abdominal compressions (AC-CPR).

Resuscitation arterial waveform quantification and outcomes in pediatric bidirectional Glenn and Fontan patients.

Background: Resuscitation with chest compressions and positive pressure ventilation in Bidirectional Glenn (BDG) or Fontan physiology may compromise passive venous return and accentuate neurologic injury. We hypothesized that arterial pressure and survival would be better in BDG than Fontan patients.

Methods: Secondary analyses of the Pediatric Intensive Care Quality of CPR and Improving Outcomes from Pediatric Cardiac Arrest databases.

Epinephrine Dosing Intervals Are Associated With Pediatric In-Hospital Cardiac Arrest Outcomes: A Multicenter Study.

Objectives: Data to support epinephrine dosing intervals during cardiopulmonary resuscitation (CPR) are conflicting. The objective of this study was to evaluate the association between epinephrine dosing intervals and outcomes. We hypothesized that dosing intervals less than 3 minutes would be associated with improved neurologic survival compared with greater than or equal to 3 minutes.

Chest compressions for pediatric organized rhythms: A hemodynamic and outcomes analysis.

Aim: Pediatric cardiopulmonary resuscitation (CPR) guidelines recommend starting CPR for heart rates (HRs) less than 60 beats per minute (bpm) with poor perfusion. Objectives were to (1) compare HRs and arterial blood pressures (BPs) prior to CPR among patients with clinician-reported bradycardia with poor perfusion ("BRADY") vs. pulseless electrical activity (PEA); and (2) determine if hemodynamics prior to CPR are associated with outcomes.

Identification of post-cardiac arrest blood pressure thresholds associated with outcomes in children: an ICU-Resuscitation study.

Introduction: Though early hypotension after pediatric in-hospital cardiac arrest (IHCA) is associated with inferior outcomes, ideal post-arrest blood pressure (BP) targets have not been established. We aimed to leverage prospectively collected BP data to explore the association of post-arrest BP thresholds with outcomes. We hypothesized that post-arrest systolic and diastolic BP thresholds would be higher than the currently recommended post-cardiopulmonary resuscitation BP targets and would be associated with higher rates of survival to hospital discharge.

Survival With Favorable Neurologic Outcome and Quality of Cardiopulmonary Resuscitation Following In-Hospital Cardiac Arrest in Children With Cardiac Disease Compared With Noncardiac Disease.

Objectives: To assess associations between outcome and cardiopulmonary resuscitation (CPR) quality for in-hospital cardiac arrest (IHCA) in children with medical cardiac, surgical cardiac, or noncardiac disease.

Design: Secondary analysis of a multicenter cluster randomized trial, the ICU-RESUScitation Project (NCT02837497, 2016-2021).

Setting: Eighteen PICUs.

Outcomes and characteristics of cardiac arrest in children with pulmonary hypertension: A secondary analysis of the ICU-RESUS clinical trial.

Background: Previous studies have identified pulmonary hypertension (PH) as a relatively common diagnosis in children with in-hospital cardiac arrest (IHCA), and preclinical laboratory studies have found poor outcomes and low systemic blood pressures during CPR for PH-associated cardiac arrest. The objective of this study was to determine the prevalence of PH among children with IHCA and the association between PH diagnosis and intra-arrest physiology and survival outcomes.

Methods: This was a prospectively designed secondary analysis of patients enrolled in the ICU-RESUS clinical trial (NCT02837497).

Diastolic Blood Pressure Threshold During Pediatric Cardiopulmonary Resuscitation and Survival Outcomes: A Multicenter Validation Study.

Objectives: Arterial diastolic blood pressure (DBP) greater than 25 mm Hg in infants and greater than 30 mm Hg in children greater than 1 year old during cardiopulmonary resuscitation (CPR) was associated with survival to hospital discharge in one prospective study. We sought to validate these potential hemodynamic targets in a larger multicenter cohort.

Design: Prospective observational study.

The Temporal Association of the COVID-19 Pandemic and Pediatric Cardiopulmonary Resuscitation Quality and Outcomes.

Objectives: The COVID-19 pandemic resulted in adaptations to pediatric resuscitation systems of care. The objective of this study was to determine the temporal association between the pandemic and pediatric in-hospital cardiac arrest (IHCA) process of care metrics, cardiopulmonary resuscitation (cardiopulmonary resuscitation) quality, and patient outcomes.

Design: Multicenter retrospective analysis of a dataset comprising observations of IHCA outcomes pre pandemic (March 1, 2019 to February 29, 2020) versus pandemic (March 1, 2020 to February 28, 2021).

Management of Hypertrophic Cardiomyopathy in a Newborn with Dextro-Transposition of the Great Arteries.

Impaired maternal glucose metabolism during pregnancy can have significant effects on the cardiovascular system of the developing fetus. Early in pregnancy the teratogenic effects may lead to structural heart defects, while later in gestation a form of hypertrophic cardiomyopathy can develop due to overgrowth driven by fetal hyperinsulinism. We describe an infant with the uncommon combination of both dextro-transposition of the great arteries and hypertrophic cardiomyopathy.

Effect of Physiologic Point-of-Care Cardiopulmonary Resuscitation Training on Survival With Favorable Neurologic Outcome in Cardiac Arrest in Pediatric ICUs: A Randomized Clinical Trial.

Importance: Approximately 40% of children who experience an in-hospital cardiac arrest survive to hospital discharge. Achieving threshold intra-arrest diastolic blood pressure (BP) targets during cardiopulmonary resuscitation (CPR) and systolic BP targets after the return of circulation may be associated with improved outcomes.

Objective: To evaluate the effectiveness of a bundled intervention comprising physiologically focused CPR training at the point of care and structured clinical event debriefings.
