Objectives: Opioid-associated fatal and non-fatal overdose rates continue to rise. Prehospital overdose education and naloxone distribution (OEND) programs are attractive harm-reduction strategies, as patients who are not transported by EMS after receiving naloxone have limited access to other interventions. This narrative summary describes our experiences with prehospital implementation of evidence-based OEND practices across Ohio as part of the HEALing Communities Study (HCS).

Fluid resuscitation choices in prehospital trauma care are limited, with most Emergency Medical Services (EMS) agencies only having access to crystalloids. Which solution to use, how much to administer, and judging the individual risks and benefits of giving or withholding fluids remains an area of uncertainty. To address the role of crystalloid fluids in prehospital trauma care, we reviewed the available relevant literature and developed recommendations to guide clinical care.

Background: Sustainable Development Goals (SDGs) are universally recognised targets designed to combat poverty, inequality, and climate change. However, there exists limited awareness and understanding of these goals among nursing and midwifery students. To address this knowledge gap, a co-designed audio podcast was introduced as an educational tool to enhance students' comprehension of SDGs and their relevance to the healthcare profession.

Article Synopsis
  • The Communities That HEAL (CTH) intervention aimed to boost naloxone distribution in communities severely affected by opioid overdoses compared to standard care.
  • A study involving 67 communities in Kentucky, Massachusetts, New York, and Ohio revealed that naloxone distribution was significantly higher (79% more) in the CTH intervention group than in the usual care group over a year of monitoring.
  • The findings suggest that the CTH intervention effectively increased naloxone distribution, supporting its role in reducing opioid-related overdose deaths.

Article Synopsis
  • The study examines a community-based intervention aimed at reducing opioid-related overdose deaths by increasing the adoption of evidence-based practices including overdose education and naloxone distribution, medication treatment for opioid use disorder, and prescription safety.
  • In a cluster-randomized trial, 67 communities across Kentucky, Massachusetts, New York, and Ohio were assigned to either receive the intervention or serve as a control group during a period marked by the COVID-19 pandemic and an increase in fentanyl overdoses.
  • Results showed no significant difference in opioid-related overdose death rates between the intervention and control groups, with both averaging similar rates, indicating that the community-engaged strategies did not have a measurable impact during the study period.

Study Objective: To evaluate if out-of-hospital administration of fentanyl and intranasal ketamine, compared to fentanyl alone, improves early pain control after injury.

Methods: We conducted an out-of-hospital randomized, placebo-controlled, blinded, parallel group clinical trial from October 2017 to December 2021. Participants were male, aged 18 to 65 years, receiving fentanyl to treat acute traumatic pain prior to hospital arrival, treated by an urban fire-based emergency medical services agency, and transported to the region's only adult Level I trauma center.

Background: In the prehospital tranexamic acid (TXA) for traumatic brain injury (TBI) trial, TXA administered within 2 hours of injury in the out-of-hospital setting did not reduce mortality in all patients with moderate/severe traumatic brain injury (TBI). We examined the association between TXA dosing arms, neurologic outcome, and mortality in patients with intracranial hemorrhage (ICH) on computed tomography (CT).

Methods: This was a secondary analysis of the Prehospital Tranexamic Acid for TBI Trial ( ClinicalTrials.

Objective: Blood-based biomarkers play a central role in the diagnosis and treatment of critically ill patients, yet none are routinely measured during the intra-arrest phase of out-of-hospital cardiac arrest (OHCA). Our objective was to describe methodological aspects, sources of evidence, and gaps in research surrounding intra-arrest blood-based biomarkers for OHCA.

Methods: We used scoping review methodology to summarize existing literature.

Introduction: Only 5% of rare diseases have an approved treatment available, therefore patients often utilise complementary and integrative medicines (CIMs) to help manage their condition. Limited high-quality evidence-based studies are available which support the effectiveness of CIM, as it is difficult to show that an outcome is a direct result of the CIM intervention and not due to bias. Patients and healthcare professionals must weigh up the evidence quality, safety, efficacy, practical logistics, and financial implications of utilising CIM for rare diseases.

Fish is an important source of nutrients, particularly the long chain n-3 polyunsaturated fatty acids (n-3 PUFAs). The incorporation of fish into the diet has been shown to have several health benefits, including lowering the risk of cardiovascular disease (CVD). Elevated plasma lipids are one of the main modifiable risk factors contributing to CVD and may be partly mediated by n-3 PUFAs.

Background: Parkinson's Disease (PD) is a common neurological condition that often causes stiffness, tremor and slow movement. People living with PD are likely to encounter nursing students throughout their journey from pre-diagnosis to death. Despite this, there is a paucity of evidence about current practice in PD education amongst nursing students.

Guidelines from the Office for Human Research Protections regarding categories of research that institutional review boards (IRBs) may review through expedited procedures limit the volume of blood that can be obtained from research participants for minimal risk research purposes. As defined by the Common Rule, minimal risk research is research in which the probability and magnitude of harm or discomfort anticipated are not greater than the probability and magnitude of harm or discomfort encountered from routine clinical tests. For this study, we considered the volume of remnant blood following routine clinical tests in light of the current definition of minimal risk in research.

Background: Tenets of high-quality out-of-hospital cardiac arrest (OHCA) resuscitation include early recognition and treatment of shockable rhythms, and minimizing interruptions in compressions. Little is known about how use of a mechanical compression device affects these elements. We hypothesize that use of such a device is associated with prolonged pauses in compressions to apply the device, and long compression intervals overall.

Objectives: Many people living with a rare disease (RD) are cared for by a family member. Due to a frequent lack of individual RD knowledge from healthcare professionals, the patient and their informal caregiver are frequently obliged to become 'experts' in their specific condition. This puts a huge strain on family life and results in caregivers juggling multiple roles in addition to unique caring roles including as advocate, case manager and medical navigator.
