Trauma & Triage Geriatric Teaching Moments from A.J. Heightman, MPA, EMT-P – JEMS Editor-in-Chief relative to the Texas Church Mini Bus Crash that Killed 13 Senior Citizens
When 13 senior citizens were killed in a horrible head-on collision between a San Antonio church mini bus and a pickup truck in southwest Texas, the AP story noted that the elderly occupants “were more susceptible to internal injuries and damage to vulnerable organs because of their advanced ages.” (see below as presented by the Associated Press). As an educator who spends a lot of time educating crews about the unique impact trauma can have on geriatric patients, I thought I would take the opportunity to present a few important facts about geriatric trauma and assessment tips to remember when you are tasked with triag...

What is the role of screening for pulmonary hypertension in adults and children with sickle cell disease?
Authors: Willen SM, Gladwin MT
Abstract
Patient case: An 18-year-old male patient with homozygous hemoglobin SS disease was evaluated for progressive dyspnea and elevated tricuspid regurgitant jet velocity (TRV) on echocardiography. The patient's case is described in detail in Lancet1 He had been treated with regular transfusions since childhood for stroke, had rare episodes of vaso-occlusive pain episodes, and did not take narcotic pain medications. He presented with progressive severe dyspnea on exertion and lower extremity edema. His laboratory tests were notable for a total hemoglobin level of 11.8 g/dL and hem...

Crossed aphasia following cerebral infarction in a right-handed patient with atypical cerebral language dominance
ConclusionThe findings suggest that the patient has right-sided cerebral language dominance, or that both hemispheres have linguistic functions. Not all patients show linguistic capabilities on the side opposite hand preference. The language dominance should be predicted by a combination of clinical manifestations and functional imaging techniques.

Development of a cerebrovascular magnetic resonance imaging biomarker for cognitive aging
ObjectiveRecent availability of amyloid and tau positron emission tomography (PET) has provided us with a unique opportunity to measure the association of systemic vascular health with brain health after accounting for the impact of Alzheimer disease (AD) pathologies. We wanted to quantify early cerebrovascular health –related magnetic resonance imaging brain measures (structure, perfusion, microstructural integrity) and evaluate their utility as a biomarker for cerebrovascular health.MethodsWe used 2 independent samples (discovery, n = 390; validation, n = 1,035) of individuals, aged ≥ 60 years, along the...

Abnormal Cerebral Perfusion Profile in Older Adults with HIV-Associated Neurocognitive Disorder: Discriminative Power of Arterial Spin-Labeling FUNCTIONAL
CONCLUSIONS:
This study found specific CBF patterns associated with HIV status despite viral suppression—data that should animate further investigations into the pathobiologic basis of vascular and cognitive abnormalities in HIV-associated neurocognitive disorders.

Potential applications of FDG-PET/MRI in detecting vascular dementia
Conclusions: FDG-PET/MRI may be a valuable tool in the diagnosis of VaD. However, the paucity of data in the field necessitates a further analysis of its similarity to FDG-PET/CT in results. Novel studies should be conducted to explore various scanners, patient populations, and MRI protocols to better inform the identification of VaD.

What are Some Risk Factors for Hypoxic-Ischemic Encephalopathy Outcomes?
Discussion
“Neonatal encephalopathy, manifesting as altered responsiveness, seizures, apnea and abnormal muscle tone and reflexes, resulting from hypoxic-ischemic injury is termed hypoxic-ischemic encephalopathy (HIE).” Neonatal encephalopathy can be associated with other problems including stroke, hemorrhage, infection, pre-term brain injury and hypoglycemia as some examples. Sometimes more than one of these entities occurs simultaneously such as hypoglycemia and HIE. HIE can result in long-term neurological problems including motor, behavioral, and cognitive problems that can become apparent even years later....

O-038 Sympathetic nervous system activation causes cerebral perfusion deficit and cerebral vasoconstriction in Swine
ConclusionIn swine, electrical stimulation of SCG results in reproducible cerebral vasoconstriction and perfusion deficit comparable to cerebral vasospasm. This can be inhibited by prior local anesthetic injection into the SCG, a possible therapeutic target for cerebral vasospasm.Abstract O-038 Figure 1CT perfusion scan (top row) coronel view of approximate fronto-temporal area of swine brain (outlined in white box) at baseline, with right SCG stimulation, with lidocainc + right SCG stimulation.

When does life end? New organ donation strategy fuels debate
On a chilly holiday Monday in January 2020, a medical milestone passed largely unnoticed. In a New York City operating room, surgeons gently removed the heart from a 43-year-old man who had died and shuttled it steps away to a patient in desperate need of a new one.
More than 3500 people in the United States receive a new heart each year. But this case was different—the first of its kind in the country. “It took us 6 months to prepare,” says Nader Moazami, surgical head of heart transplantation at New York University (NYU) Langone Health, where the operation took place. The run-up included oversight from an ethi...
