SARS-CoV-2 (COVID-19) Experience at an Academic Medical Examiner's Office.

Introduction: The coronavirus disease of 2019 (COVID-19) pandemic has resulted in a great deal of morbidity and mortality worldwide. Since most deaths related to COVID-19 are currently considered natural, and they tend to occur following a clinically recognized illness, many medical examiner/coroner offices within the United States do not take jurisdiction over the majority of COVID-19 deaths.

Methods: In this review, we present the experience of a medium-sized medical examiner's office affiliated with an academic medical school institution, over the first 15 months of the COVID-19 pandemic.

Proximity interactome of lymphatic VE-cadherin reveals mechanisms of junctional remodeling and reelin secretion.

The adhesion receptor vascular endothelial (VE)-cadherin transduces an array of signals that modulate crucial lymphatic cell behaviors including permeability and cytoskeletal remodeling. Consequently, VE-cadherin must interact with a multitude of intracellular proteins to exert these functions. Yet, the full protein interactome of VE-cadherin in endothelial cells remains a mystery.

Meningeal lymphatic CGRP signaling governs pain via cerebrospinal fluid efflux and neuroinflammation in migraine models.

Recently developed antimigraine therapeutics targeting calcitonin gene-related peptide (CGRP) signaling are effective, though their sites of activity remain elusive. Notably, the lymphatic vasculature is responsive to CGRP signaling, but whether meningeal lymphatic vessels (MLVs) contribute to migraine pathophysiology is unknown. Mice with lymphatic vasculature deficient in the CGRP receptor (CalcrliLEC mice) treated with nitroglycerin-mediated (NTG-mediated) chronic migraine exhibit reduced pain and light avoidance compared with NTG-treated littermate controls.

Lethal Complications of Meningiomas: A Case Series.

Background: Meningiomas are the most prevalent type of primary intracranial tumor in adults, comprising nearly one-third of all intracranial tumors. They are typically benign, slow-growing, and asymptomatic but may cause neurological symptoms as they expand due to mass effect. Classification is determined by World Health Organization (WHO) grades 1 to 3 following pathological examination corresponding to benign, atypical, and anaplastic (malignant), respectively, reflecting their rate of growth and risk of recurrence.

Coumestrol induces oxidative stress and impairs migration and embryonic growth.

In Brief: Healthy development of the placenta is dependent on trophoblast cell migration and reduced oxidative stress presence. This article describes how a phytoestrogen found in spinach and soy causes impaired placental development during pregnancy.

Abstract: Although vegetarianism has grown in popularity, especially among pregnant women, the effects of phytoestrogens in placentation lack understanding.

Empowering Indigenous Communities Through a Participatory, Culturally Responsive Evaluation of a Federal Program for Older Americans.

This article describes our experience of conducting a 5-year, culturally responsive evaluation of a federal program with Indigenous communities. It describes how we adapted tenets from "participatory evaluation models" to ensure cultural relevance and empowerment. We provide recommendations for evaluators engaged in similar efforts.

Period poverty: The perceptions and experiences of impoverished women living in an inner-city area of Northwest England.

Background: The menstrual needs of girls and women are important to health, education, and well-being. Unmet need and harm from poor menstrual health in low-and- middle-income countries have been documented, but with little empirical research undertaken in high income countries. Continuing austerity in the UK suggests menstruators are likely more vulnerable to 'period poverty' than previously, with the COVID-19 pandemic assumed to exacerbate the situation.

Death After Poison Ivy Smoke Inhalation.

Urushiol, the active antigen in poison ivy ( Toxicodendron radicans ), is frequently associated with type I and type III hypersensitivity reactions. These reactions most often result in cutaneous symptoms that vary in severity and may at times require medical interventions. Injuries involving other body systems associated with urushiol exposure are far less common.

Building connection and improving health for Indigenous elders: Findings from the Title VI evaluation.

Background: As the older Indigenous population in the United States expands, there is a growing demand for programs to address age-related needs. Although Title VI of the OAA provides culturally responsive strategies to support elders through home- and community-based nutrition services, these programs have not been the subject of a national evaluation; our study is the first.

Methods: We conducted a mixed-methods study to assess the impact of the Title VI programs on elders.

Longitudinal Opioid Surveillance Project Involving Toxicologic Analysis of Postmortem Specimens from 9 Counties in Michigan Suggests the Discovery of New High-Intensity Drug Trafficking Areas.

Acetyl fentanyl (AF) is a Schedule I fentanyl analog that has been increasingly seen in heroin and fentanyl polydrug toxicity overdoses in Michigan (MI). Drug users are often unaware of the presence of AF in their drugs because it is often sold mixed into or disguised as heroin. High levels of AF in heroin drug products can cause increased incidence of overdose.

Method to Evaluate the Age of Groundwater Inputs to Surface Waters by Determining the Chirality Change of Metolachlor Ethanesulfonic Acid (MESA) Captured on a Polar Organic Chemical Integrative Sampler (POCIS).

We previously discovered a method to estimate the groundwater mean residence time using the changes in the enantiomeric ratio of metolachlor ethanesulfonic acid (MESA), (2-[(2-ethyl-6-methylphenyl)(2-methoxy-1-methylethyl)amino]-2-oxoethanesulfonic acid), a metabolite of the herbicide metolachlor. However, many grab samples would be needed for each watershed over an extended period, and this is not practical. Thus, we examined the use of a polar organic chemical integrative sampler (POCIS) deployed for 28 days combined with a modified liquid chromatography-mass spectrometry LC-MS/MS method to provide a time-weighted average of the MESA enantiomeric ratio.

Distinct Functional Connectivity Patterns Are Associated With Social and Cognitive Lifestyle Factors: Pathways to Cognitive Reserve.

The importance of diverse lifestyle factors in sustaining cognition during aging and delaying the onset of decline in Alzheimer's disease and related dementias cannot be overstated. We explored the influence of cognitive, social, and physical lifestyle factors on resting-state lagged linear connectivity (LLC) in high-density electroencephalography (EEG) in adults, ages 35-75 years. Diverse lifestyle factors build cognitive reserve (CR), protecting cognition in the presence of physical brain decline.

Towards onset prevention of cognition decline in adults with Down syndrome (The TOP-COG study): A pilot randomised controlled trial.

Background: Dementia is very common in Down syndrome (trisomy 21) adults. Statins may slow brain amyloid β (Aβ, coded on chromosome 21) deposition and, therefore, delay Alzheimer disease onset. One prospective cohort study with Down syndrome adults found participants on statins had reduced risk of incident dementia, but there are no randomised controlled trials (RCTs) on this issue.

Novel use of dexmedetomidine for the treatment of anticholinergic toxidrome.

Introduction: We report the case of an adolescent with anticholinergic toxidrome from diphenhydramine overdose, whose symptoms were treated with a novel application of dexmedetomidine.

Case Report: A 13-year-old female developed an anticholinergic toxidrome after intentionally ingesting 9.5 mg/kg of diphenhydramine.

Histone H4 acetylation by immunohistochemistry and prognosis in relapsed acute lymphocytic leukaemia (ALL).

Histone H4 acetylation was examined by immunohistochemistry in patients with acute lymphocytic leukaemia (ALL) in first relapse. Univariate and multivariate models identified correlates of complete remission (CR) and overall survival (OS). No variables were associated with achievement of CR.

Histone H4 acetylation by immunohistochemistry and prognosis in newly diagnosed adult acute lymphoblastic leukemia (ALL) patients.

Background: Histone deacetylase (HDAC) inhibitors are a novel anti-tumor therapy. To determine whether HDAC inhibitors may be useful in the treatment of adult acute lymphoblastic leukemia (ALL), we examined the acetylation of histone H4 by immunohistochemistry in newly diagnosed ALL patients and evaluated the impact of acetylation on complete remission (CR) rate, relapse-free survival (RFS), and overall survival (OS).

Methods: Patients > or = 18 years of age and an available diagnostic bone marrow biopsy were evaluated.
