Prenatal ethanol exposure can cause a broad range of abnormalities in newborns known as Fetal Alcohol Spectrum Disorder (FASD). Despite significant progress in understanding the disease mechanisms of FASD, there remains a strong global need for effective therapies. To evaluate the therapeutic potential of sulforaphane (SFN), an active compound extracted from cruciferous vegetables, in preventing FASD, ethanol-exposed zebrafish embryos were pretreated, co-treated, or post-treated with various concentrations of SFN.

Introduction: The mechanistic role of glucagon-like peptide-1 (GLP-1) and GLP-1 receptor agonists (GLP-1RAs) in modulating brain functional activity has been inadequately examined. Mental disorders are characterized by dysregulated functional connectivity in brain circuits that subserve phenomenology. We conducted a comprehensive synthesis of known effects of GLP-1 and GLP-1RAs on functional connectivity.

[Drug-induced QT interval prolongation. Evaluating the prevalence of potentially fatal cardiac arrhythmias in a specific cohort of patients].

MMW Fortschr Med

November 2024

Institut für Rechtsmedizin, Klinikum Innenstadt der LMU München, Nußbaumstraße 26, 80336, München, Deutschland.

Article Synopsis
  • Some medications can increase the QT interval, which can be life-threatening, especially when combined with other risk factors.
  • In a study of 3040 forensic autopsy cases over five years, 6% showed at least one drug that could prolong the QT interval among individuals with undetermined causes of death.
  • Key risk factors linked to fatal heart issues included a history of drug or alcohol abuse, heart problems, and the use of multiple QT-prolonging medications, with antipsychotics being the most commonly found among these cases.

Department of Pathology, University of Utah Health, Salt Lake City, UT, USA; ARUP Institute for Clinical and Experimental Pathology, 500 Chipeta Way, Salt Lake City, UT 84108, USA.

Article Synopsis
  • Racial disparities in drug testing for substance-use disorders highlight systemic inequalities, with Black and Hispanic Americans facing disproportionate scrutiny despite similar drug use rates as other groups.
  • * These biases affect employment, legal outcomes, and access to treatment, perpetuating a cycle of discrimination and marginalization.
  • * To combat these issues, there's a need for policy reform, heightened awareness of implicit biases, and equitable healthcare practices to ensure fair treatment for all individuals dealing with substance-use disorders.

Cannabis Use During Early Pregnancy Following Recreational Cannabis Legalization.

JAMA Health Forum

November 2024

Division of Research, Kaiser Permanente Northern California, Pleasanton.

Importance: It is unknown whether state recreational cannabis legalization (RCL) is related to increased rates of prenatal cannabis use or whether RCL-related changes vary with cannabis screening methods or the local policy environment.

Objective: To test whether RCL in California was associated with changes in prenatal cannabis use rates, whether changes were evident in both self-report and urine toxicology testing, and whether rates varied by local policies banning vs allowing adult-use retailers post-RCL.

Design, Setting, And Participants: This population-based time-series study used data from pregnancies in Kaiser Permanente Northern California universally screened for cannabis use during early pregnancy by self-report and toxicology testing from January 1, 2012, to December 31, 2019.

Dengue, a mosquito-borne viral infection caused by the dengue virus (DENV), is a global health challenge. Annually, approximately 400 million cases are reported worldwide, signaling a persistent upward trend from previous years and projected a manifold increase in the future. There is a growing need for innovative and integrated approaches aimed at effective disease management.

Article Synopsis
  • Clinicians often rely on patients' self-reports regarding substance use in cases of acute drug toxicity, but this study assesses the reliability of those reports compared to laboratory findings in serum samples.
  • A cohort of 1,000 adults with acute drug toxicity was analyzed over a year, focusing on the accuracy of self-reported drug use against identified substances through advanced mass spectrometry.
  • Results indicated that while most patients were fairly accurate in reporting drug classes used, with a positive predictive value of 0.68 and a negative predictive value of 0.90, substantial discrepancies were noted between reported and detected substances, particularly for hallucinogens.

Teratology investigates the origins of congenital disabilities, often linked to environmental factors such as ethanol (EtOH) exposure. Ethanol at 150 μM has been associated with teratogenic effects, oxidative stress, immunological responses, and endocrine disruptions. Fetal alcohol spectrum disorder (FASD) arises from maternal alcohol consumption during pregnancy, leading to developmental delays and cognitive impairment.

Introduction: Substance abuse is a major public health problem. In recent years, ketamine, which is a parenteral anesthetic, has been consumed increasingly as an illicit drug together with alcohol, although little is known of how this association alters brain activity. The present study investigated the influence of progressive doses of ketamine, associated with alcohol, on electrophysiological activity.

Selective serotonin reuptake inhibitor (SSRI) antidepressants such as fluoxetine are used in combination with the medical psychostimulant methylphenidate (Ritalin) in a variety of treatments in children and adults. Unintended co-exposure to these psychotropic medications also occurs in patients on SSRIs who abuse methylphenidate as a "cognitive enhancer" or recreational drug. Preclinical research shows that SSRIs such as fluoxetine when given in conjunction with methylphenidate potentiate addiction-related gene regulation by methylphenidate in the striatum, consistent with the known facilitatory role for serotonin in psychostimulant-induced neuronal and behavioral changes.

Digital health refers to the use of information and communication technologies in medicine (including smartphone apps, wearables, other non-invasive sensors, informatics and telehealth platforms) to prevent illness, deliver treatment, and promote wellness. This rapidly proliferating group of technologies has the potential to reduce harm for people with opioid use disorder (OUD) and facilitate the recovery process; however, development in this space for OUD has been slower compared to that for other medical conditions. Unique issues with OUD management surrounding patient provider relationships, interaction with the healthcare system, autonomy and trust sometimes hinder care approaches, including those in digital health.
