Aging and MPTP Sensitivity Depend on Molecular and Ultrastructural Signatures of Astroglia and Microglia in Mice Substantia Nigra.

Both astroglia and microglia show region-specific distribution in CNS and often maladapt to age-associated alterations within their niche. Studies on autopsied substantia nigra (SN) of Parkinson's disease (PD) patients and experimental models propose gliosis as a trigger for neuronal loss. Epidemiological studies propose an ethnic bias in PD prevalence, since Caucasians are more susceptible than non-whites.

Maternal Cannabis Use During Pregnancy and Neuropsychiatric Adverse Outcomes During Childhood and Early Adult Life.

Cannabis use during pregnancy is increasing; the study of adverse outcomes in cannabis-exposed pregnancies is therefore important. Previous articles in this series described increased risks of maternal adverse outcomes, fetal adverse outcomes, birth defects in newborns, and autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) in childhood. This article examines neuropsychiatric adverse outcomes in offspring gestationally exposed to cannabis.

A Gas Chromatography-Mass Spectrometry Method to Determine Tramadol Abuse Using Urine Samples.

Background The synthetic opioid tramadol is widely used as a pain reliever. Unlike other opioids, it is used freely worldwide, unaffected by international controls resulting in abuse and accidental intoxication. Analytical methods are necessary to prove tramadol abuse because 30% of the drug is excreted unchanged.

Maternal Cannabis Use in Pregnancy and Autism Spectrum Disorder or Attention-Deficit/Hyperactivity Disorder in Offspring.

Up to 10% of women may use cannabis during pregnancy; this is of concern because constituents of cannabis cross the placental barrier and potentially influence neurodevelopment by acting on cannabinoid receptors in the developing fetal brain. In this context, a recent meta analysis of 13 observational studies found that gestational exposure to cannabis was associated with a small increase in the risk of autism spectrum disorder (ASD; relative risk [RR], 1.30) and with an even smaller increase in the risk of attention deficit/hyperactivity disorder (ADHD; RR, 1.

Randomized Controlled Trials of Psilocybin-Assisted Therapy in the Treatment of Major Depressive Disorder: Systematic Review and Meta-Analysis.

Introduction: There is growing interest in the use of psychedelic-assisted therapy (PAT) for major depressive disorder (MDD), including treatment-resistant depression. We used randomized controlled trial (RCT) data to compare summary estimates of change in depression ratings with PAT versus comparator treatments in MDD. We also compared response and remission rates, and adverse effects.

Strategies in Parkinson's Disease Therapeutics - A Need for Synergy of Ayurveda, Small Molecules and Nanoparticles aided Approaches.

Despite extensive research, there is an unmet need for developing disease-modifying therapies for Parkinson's disease (PD). Failure of certain landmark clinical trials has highlighted the need for a better understanding of the disease pathogenesis as well as identifying the hurdles in developing drug candidates and designing clinical trials. While adhering to these needs, several promising trials are currently underway with the hope of developing reliable targets.

Towards a Further Understanding of Meta-Analysis Using Gestational Exposure to Cannabis and Birth Defects as a Case in Point.

About 5%-10% of pregnancies in the US are exposed to cannabis with highest use reported during the first trimester. Two recent meta-analyses presented estimates of the risk of birth defects associated with prenatal exposure to cannabis; the larger and more recent meta-analysis pooled data from 18 cohort and 18 case-control studies with a total sample size of >19 million subjects. The meta-analyses found that prenatal exposure to cannabis was associated with a small but statistically significant increased risk of any birth defect (pooled odds ratios [ORs], 1.

Neuroprotective effects of nutraceuticals and natural products in traumatic brain injury.

Traumatic Brain Injury (TBI) is a global healthcare concern with considerable mortality and morbidity. Early diagnosis and timely treatment are critical for optimal clinical prognosis in TBI patients. Injury to the brain tissue following TBI is categorized into primary and secondary injury events, with the former being acute, while the latter evolves over a long period.

Exposure of Pregnancy to Pregestational Diabetes, Gestational Diabetes, and Antidiabetic Medications With Especial Focus on Major Congenital and Cardiac Malformations in Offspring.

The global prevalence of type 2 diabetes mellitus (T2DM) is increasing. T2DM is more common in patients with psychiatric disorders and those who take certain psychotropic drugs. T2DM occurs in 2%-7% of women of reproductive age.

Regression: Understanding What Covariates and Confounds Do in Adjusted Analyses.

The use of regression analysis is common in research. This article presents an introductory section that explains basic terms and concepts such as independent and dependent variables (IVs and DVs), covariates and confounds, zero-order correlations and multiple correlations, variance explained by variables and shared variance, bivariate and multivariable linear regression, line of least squares and residuals, unadjusted and adjusted analyses, unstandardized () and standardized (β) coefficients, adjusted , interaction terms, and others. Next, this article presents a more advanced section with the help of 3 examples; the raw data files for these examples are included in supplementary materials, and readers are encouraged to download the data files and run the regressions on their own in order to better follow what is explained in the text (this, however, is not mandatory, and readers who do not do so can also follow the discussions in the text).

Therapeutic Effects, Side Effects, and Adverse Effects of Neuropsychiatric Drugs in the Context of Treating Cancer-Related Anorexia With Olanzapine and Mirtazapine.

Drugs have actions that may be classified as therapeutic effects and side effects; side effects are actions that do not contribute to therapeutic benefit. Some side effects are neutral; others, experienced as undesirable or unpleasant, are recorded as adverse effects. Some drug actions are therapeutic for some disorders and adverse for others; or therapeutic during acute illness and adverse during maintenance treatment.

A randomised, open-label, pragmatic pilot comparison of oral and intravenous ketamine in treatment-resistant depression.

Background: For depression, ketamine is more conveniently administered by oral than by intravenous (iv) routes. The relative antidepressant efficacy of oral vs iv ketamine is unknown.

Objectives: To assess the acute efficacy and the persistence of improvement with open-label oral versus iv ketamine in outpatients with treatment-resistant depression (TRD).

Epilepsy, Antiepileptic Drugs, and Adverse Pregnancy Outcomes, 2: Major Congenital Malformations With Antiepileptic Drug Monotherapy.

Women with epilepsy (WWE) are usually advised antiepileptic drug (AED) treatment even during pregnancy. It is therefore important to know what the major congenital malformation (MCM) risks might be with untreated epilepsy, and with first-trimester exposure to different AEDs in monotherapy. This article reviews recent findings from a large multinational registry, a large multinational population based study, and a large meta-analysis.

Primary outcomes, secondary outcomes, and their relevance to how many papers are published from a study: A primer for authors, reviewers, and editors.

In research, outcomes are often categorized as primary and secondary. The primary outcome is the most important one; it determines whether the study is considered 'successful' or not. Secondary outcomes are chosen because they provide supporting evidence for the results of the primary outcome or additional information about the subject being studied.

Yoga as an Adjuvant with Multimodal Psychological Interventions for Excessive Use of Technology: A Randomized Controlled Trial from India.

Background: Multimodal approach of psychotherapy has been found to be effective for managing the excessive use of technology. Yoga, a holistic mind-body therapy, has been observed to be a useful adjuvant in managing substance use disorders. Yoga is also known to reduce stress and enhance overall well-being.

Epilepsy, Antiepileptic Drugs, and Adverse Pregnancy Outcomes, 1: Examination and Interpretation of Recent Research.

The age-standardized global prevalence of epilepsy is about 0.3% in women. Seizures are associated with morbidity and mortality risks; so, women with epilepsy (WWE) are usually advised antiepileptic drug (AED) treatment even during pregnancy.

Antipsychotic Medication Continuation vs Taper and Discontinuation in Patients With Schizophrenia and Other Nonaffective Psychotic Disorders.

Schizophrenia is a major mental illness that is managed with long-term antipsychotic medication as a standard of care. Antipsychotic medications, however, are associated with many subjective and objective adverse effects. These adverse effects have driven the study of risk-mitigation strategies such as targeted intermittent therapy and dose reduction and drug discontinuation.
