Acute mesenteric ischemia (AMI) is a condition that results from a sudden decline in blood flow through the mesenteric vessels that has a high morbidity and mortality. Non-occlusive AMI often presents in critically ill, hypotensive patients that suffer from decreased organ perfusion. ⋯ The patient required rapid fluid resuscitation in the emergency department. He did not require surgical intervention and was able to be discharged home with resolution of symptoms after a 7-day inpatient stay.

The purpose of this retrospective, cross-sectional study was to determine and analyze the trends in ocular injuries related to landscaping activities and equipment from 2010 to 2019. A total of 168,845 ocular injuries were associated with landscaping activities with the majority of cases occurring in men (80.4%) between the ages of 41-60 during the summer months of June, July, and August. The majority of ocular injuries did not require admission (97.8%) but of those that were admitted 42% had an open globe injury (n = 399). The results of this investigation provide useful information for emergency room physicians and ophthalmologists in understanding the prevalence of these landscaping-associated ocular injuries and further draw suspicion for the incidence of open globe injuries in this population.

Case Reports
Point of care ultrasound needle guidance to assist diagnosis of acute gluteal compartment syndrome.
Gluteal compartments can be difficult to assess for acute compartment syndrome (ACS) compared to other fascial compartments due to their anatomy and rarity of presentation. Point-of-care ultrasound (POCUS) needle guidance may assist in obtaining accurate compartment pressure measurements within the gluteal compartments. We present a case in which a 69-year-old woman presented following a fall resulting in a superior prosthetic hip dislocation. ⋯ The patient was subsequently taken for emergent fasciotomy and hematoma evacuation. There has been limited investigation into compartment pressure measurement under US guidance versus a palpation/landmark-guided technique. This case shows the feasibility of US needle guidance when assessing compartment pressures for this uncommon diagnosis.

Out-of-hospital cardiac arrest (OHCA) is a leading cause of death, and research has identified limitations in analyzing the factors related to the incidence of cardiac arrest and the frequency of bystander cardiopulmonary resuscitation. This study conducts a cluster analysis of the correlation between location-related factors and the outcome of patients with OHCA using two machine learning methods: variational autoencoder (VAE) and the Dirichlet process mixture model (DPMM). ⋯ This methodology can facilitate the development of a regionalization strategy that can improve the survival rate of cardiac arrest patients in different regions.
