Cellular Mechanisms of Electromagnetic Field in Traumatic Brain Injury.

This paper presents a comprehensive review of the extant literature from 1980 through 2023 on the role and utility of Electromagnetic Fields (EMF) in the treatment of brain trauma and brain neuropathology resulting from disease. Brain trauma resulting from accident, injury and disease is a significant contributor to short and long-term morbidity, as well as a leading cause of mortality globally. To date, limited effective treatments strategies exist, and are focused primarily on symptom relief, not restoring primary preinjury function and structure. Much of the current clinical literature is based on retrospective case reports and limited animal model prospective trials exploring core etiology and alterations in post-injury clinical phenotypes. The current findings reported in the scientific literature suggest that electromagnetic therapy may hold promise as a potential non-invasive treatment for traumatic brain injury and neuropathology. Although promising, well designed clinical trials are needed to better determine its potential clinical effectiveness in this diverse patient population. Future trials will need to determine the impact of clinical variables, such as sex, age, type and extent of injury and pathology, pre-injury baseline health status and a comprehensive biopsychosocial assessment to determine a more effective personalized approach to patient care. Although initially showing promise, much work needs to be done.

Conceptualizing Addiction From an Osteopathic Perspective: Dopamine Homeostasis.

Addiction is a public health crisis in the United States. Understanding the cause and providing effective treatment for patients-in particular, those with substance use disorders-is challenging. Research has demonstrated that addiction is not a flaw in one's moral fiber or a disease of choice; rather, it is driven by alterations in neuronal mechanisms, especially those that involve the neurotransmitter dopamine, which plays a critical role in the brain's reward pathway. Much of osteopathic philosophy is based on the concept of total body homeostasis and allostasis. This article discusses the role of achieving dopamine homeostasis as part of a comprehensive biopsychosocial treatment strategy in the effective management of addiction. The authors aim to motivate osteopathic primary care physicians to incorporate osteopathic philosophy into the treatment of patients with substance use disorders.

A REVIEW OF KETAMINE ABUSE AND DIVERSION.

Ketamine was discovered in the 1960s and released for public use in 1970. Originally developed as a safer alternative to phencyclidine, ketamine is primarily used in clinical settings for analgesia and sedation. In recent years, other uses have been developed, including pain management and treatment of asthma and depression. Clinical use of ketamine causes dissociation and emergence delirium. These effects have led to recreational abuse. Although death from direct pharmacologic effects appears rare, the disinhibition and altered sensory perceptions caused by ketamine puts users at risk of environmental harm. Ketamine has also been implicated in nonconsensual sexual intercourse. Data continue to build that chronic ketamine use may lead to morbidity. Impairment of memory and persistent dissociative, depressive, and delusional thinking has also been reported with long-term use. Lower urinary tract symptoms, including cystitis have been described. Gastric and hepatic pathology have also been noted, including abnormal liver function tests, choledochal cysts and dilations of the common bile duct. S-ketamine, an enantiomer in racemic ketamine, has been shown to be hepatotoxic in vitro. Abstinence from ketamine may reduce the adverse effects of chronic use and is considered the mainstay of treatment. Specialized urine drug testing may be required to detect use, as not all point of care urine drug screens include ketamine.
