Introduction: In the Reykjavik area, a physician staffed ambulance -responded to cardiac arrests from 1982-2007. The aim of this study was to assess the outcome of attempted pre-hospital cardiac resuscitations in the period from 2004-2007 and compare to previous studies.
Material And Methods: All cases of attempted prehospital resuscitations in cardiac arrests of presumed cardiac etiology. Data was gathered according to the Utstein template.
Results: Of a total of 289 cases in cardiac arrest, resuscitation was attempted in 279 and 200 of those were presumed to have a cardiac etiology. Men were 76% of the patients and the average age was 67.7 years. Average response time was 6.3 min. One hundred and seven (54%) survived to hospital admission and 50 (25%) survived to discharge compared to 16-19% in previous studies (p=0.16). The presenting rhythm was ventricular fibrillation/ventricular tachycardia (VF/VT) in 50% of the cases, 30% was in asystole and 20% in pulseless electrical activity (PEA). Of those admitted to intensive care unit/ department and had ventricular fibrillation on the first rhythm strip 70% were discharged during 2004-2007 compared to 49% during 1999-2002 (p=0.01). Bystander CPR was provided in 62% of witnessed cases compared to 54% in a previous study (p=0.26). One hundred and twenty (60%) were witnessed cases of which 37 (31%) survived to hospital discharge compared to 5 (8%)of non witnessed cases (p<0.01).
Conclusion: One in every four cardiac arrest patients in the Reykjavik area survives to discharge. This is similar to previous studies in the area (16-19%) and high compared to international studies 3-16%. Survival of those admitted to intensive care unit/ department and had ventricular fibrillation on the first rhythm strip was significantly higher compared to previous studies. Survival was found to be significantly higher if the cardiac arrest was witnessed.

Department of Mechanical Engineering, University of Utah, Salt Lake City, UT, 84112, USA.
When infants are admitted to the hospital with skull fractures, providers must distinguish between cases of accidental and abusive head trauma. Limited information about the incident is available in such cases, and witness statements are not always reliable. In this study, we introduce a novel, data-driven approach to predict fall parameters that lead to skull fractures in infants in order to aid in determinations of abusive head trauma.

Background: Individuals with end-stage renal disease may be at increased risk of sudden cardiac arrest (SCA) associated with dialysis therapy. However, community-based studies with comprehensive adjudication of SCA are lacking.
Methods: We conducted a community-based study using a case-case study design in a US population of ≈1 million.

Introduction: The present study conducted a secondary data analysis of a comprehensive survey from Child Guidance Centers in Japan to identify factors that are associated with child abuse severity in infancy (0-3 years, 1,868 cases) and preschool age (4-6 years, 1,529 cases). A predictive model for abuse severity was developed.
Methods: The data originated from a nationwide survey that was conducted in April 2013, consisting of details of abuse cases, including child characteristics, abuser attributes, and family situation.

Department of Health and Human Performance, Nova Southeastern University, Davie, FL, USA.
Position Statement: The International Society of Sports Nutrition (ISSN) presents this position based on a critical examination of the literature surrounding the effects of long-chain omega-3 polyunsaturated fatty acid (ω-3 PUFA) supplementation on exercise performance, recovery, and brain health. This position stand is intended to provide a scientific foundation for athletes, dietitians, trainers, and other practitioners regarding the effects of supplemental ω-3 PUFA in healthy and athletic populations. The following conclusions represent the official position of the ISSN: Athletes may be at a higher risk for ω-3 PUFA insufficiency.

Background: Despite extensive research on OHCA in urban centres worldwide, there is a significant gap in knowledge regarding these events in less urbanized regions, especially in Low-Middle-Income Countries (LMICs).
Aim: To determine the characteristics and outcomes of adult out-of-hospital cardiac arrest (OHCA) in rural and suburban districts of Sindh, Pakistan.
Methods: Data of OHCA patients (>18 years) was collected retrospectively from January 2020 to December 2022, from the medical records of district and tehsil hospitals of the province of Sindh Data analysis was performed using the Statistical Package Software for the Social Sciences (SPSS) Statistics 29.
