Validation of ICD-9 Codes for Identification of Chronic Overlapping Pain Conditions.

Chronic overlapping pain conditions (COPCs) are a collection of chronic pain syndromes that often co-occur and are thought to share underlying nociplastic pathophysiology. Since they can manifest as seemingly unrelated syndromes they have historically been studied in isolation. Use of International Classification of Diseases (ICD) codes in medical records has been proposed as a means to identify and study trends in COPCs at the population level, however validated code sets are needed.

Retracing our steps to understand ketamine in depression: A focused review of hypothesized mechanisms of action.

Introduction: MDD represents a significant burden worldwide, and while a number of approved treatments exist, there are high rates of treatment resistance and refractoriness. Ketamine, an -methyl-d-aspartate receptor (NMDAR) antagonist, is a novel, rapid-acting antidepressant, however the mechanisms underlying the efficacy of ketamine are not well understood and many other mechanisms outside of NMDAR antagonism have been postulated based on preclinical data. This focused review aims to present a summary of the proposed mechanisms of action by which ketamine functions in depressive disorders supported by preclinical data and clinical studies in humans.

Warfarin Dose Requirements in Adults Hospitalized With COVID-19 Infection: A Retrospective Case Series.

Purpose: To describe the impact of hospitalization with COVID-19 infection on warfarin dose requirements in adult inpatients.

Summary: A retrospective chart review of 8 adults on warfarin admitted to Michigan Medicine with COVID-19 infection was conducted and reported as a case series. Outcomes of interest were difference in average daily dose of warfarin prior to admission (PTA) and while inpatient (IP), warfarin sensitivity, time in therapeutic range (TTR), confirmed or suspected thromboembolic event, any major or clinically significant bleeding episodes, and in-hospital mortality.

Strategies for Rotation between Gabapentinoids in the Inpatient Setting.

Guidance and evidence to support best practices in rotating between gabapentinoids is lacking. This retrospective cohort study was performed to describe and evaluate strategies for rotation. Patients rotated while admitted from June 1st, 2014 to April 25th, 2020 at a large, academic medical center were included.

Rapid Buprenorphine Induction for Cancer Pain in Pregnancy.

Most patients with cancer-related pain are managed using opioids; cancer-related pain in the setting of pregnancy can be challenging to address owing to risk to the fetus associated with opioid exposure. Buprenorphine is a unique opioid with potential benefits over other opioids for use in pregnancy and is often used for management of cancer-related pain in nonpregnant adults. There are limited data on cancer-related pain management in pregnant patients and no data supporting the use of buprenorphine for cancer-related pain in pregnant patients.

A Positive Feedback Loop of Hippo- and c-Jun-Amino-Terminal Kinase Signaling Pathways Regulates Amyloid-Beta-Mediated Neurodegeneration.

Alzheimer's disease (AD, OMIM: 104300) is an age-related disorder that affects millions of people. One of the underlying causes of AD is generation of hydrophobic amyloid-beta 42 (Aβ42) peptides that accumulate to form amyloid plaques. These plaques induce oxidative stress and aberrant signaling, which result in the death of neurons and other pathologies linked to neurodegeneration.

Alzheimer's disease: the silver tsunami of the 21(st) century.

Alzheimer's disease (AD), a fatal progressive neurodegenerative disorder, has no cure to date. One of the causes of AD is the accumulation of amyloid-beta 42 (Aβ42) plaques, which result in the onset of neurodegeneration. It is not known how these plaques trigger the onset of neurodegeneration.
