A Survey of Patient-Relevant Outcomes in Pediatric Craniopharyngioma: Focus on Hypothalamic Obesity.

Front Endocrinol (Lausanne) 2022 9;13:876770. Epub 2022 May 9.

Division of Endocrinology and Diabetes, Department of Pediatrics, Children's Hospital of Philadelphia, Philadelphia, PA, United States.

Signals of increasing co-use of stimulants and opioids from online drug forum data.

Harm Reduct J 2022 May 25;19(1):51. Epub 2022 May 25.

National Center for Injury Prevention and Control, Centers for Disease Control and Prevention, Atlanta, GA, 30341, USA.

Background: Despite recent rises in fatal overdoses involving multiple substances, there is a paucity of knowledge about stimulant co-use patterns among people who use opioids (PWUO) or people being treated with medications for opioid use disorder (PTMOUD). A better understanding of the timing and patterns in stimulant co-use among PWUO based on mentions of these substances on social media can help inform prevention programs, policy, and future research directions. This study examines stimulant co-mention trends among PWUO/PTMOUD on social media over multiple years. Read More

Stereoisomers in sports drug testing: Analytical strategies and applications.

J Chromatogr A 2022 May 17;1674:463154. Epub 2022 May 17.

Institute of Biochemistry / Center for Preventive Doping Research, German Sport University Cologne, Am Sportpark Müngersdorf 6, 50933 Cologne, Germany; European Monitoring Center for Emerging Doping Agents (EuMoCEDA), Cologne/Bonn, Germany.

Analytics employed in modern doping controls are designed to cover an extensive range of rather diverse classes of substances, all of which are banned in sport according to the list of prohibited substances and methods of doping, resulting from their potential to be performance-enhancing and/or harmful to health. Many of these bioactive substances or their metabolites are chiral, which are comprehensively characterized and, if appropriate analytical approaches are applied, can be clearly identified. In sports drug testing, the enantiomeric composition of relevant compounds is not considered in all instances, although differences of isomers concerning their biological activity have been established.

Neural Markers of Methylphenidate Response in Children With Attention Deficit Hyperactivity Disorder.

Front Behav Neurosci 2022 6;16:887622. Epub 2022 May 6.

Department of Psychiatry & Behavioral Medicine, Seattle Children's Hospital, Seattle, WA, United States.

Background: Despite widespread use of stimulants to treat ADHD, individual responses vary considerably and few predictors of response have been identified. The identification of reliable and clinically feasible biomarkers would facilitate a precision medicine approach to pharmacological treatment of ADHD. We test the hypothesis that two electroencephalography (EEG) based neural signatures of ADHD, resting aperiodic slope exponent and novelty P3 amplitude, are markers of methylphenidate response in children.

The influence of caffeinated and non-caffeinated multi-ingredient pre-workout supplements on resistance exercise performance and subjective outcomes.

J Int Soc Sports Nutr 2022 4;19(1):126-149. Epub 2022 Apr 4.

Energy Balance & Body Composition Laboratory; Department of Kinesiology & Sport Management, Texas Tech University, Lubbock, TX, USA.

Background: There is substantial consumer and practitioner interest in an emerging supplement class known as multi-ingredient pre-workout supplements (MIPS), largely due to their prevalence in resistance training communities as well as research findings demonstrating the ergogenic impact of caffeine on muscular performance. However, limited research has examined the potential efficacy of non-caffeinated MIPS, despite their growing popularity among those who are caffeine-sensitive or who train later in the day.

Methods: Twenty-four resistance-trained college-aged males (n = 12) and females (n = 12) completed three visits in which they ingested either a caffeinated MIPS (C), an otherwise identical non-caffeinated MIPS (NC), or placebo in a double-blind, counterbalanced, crossover fashion. Read More

The influence of poly-drug use patterns on the association between opioid agonist treatment engagement and injecting initiation assistance.

Subst Abuse Treat Prev Policy 2022 May 19;17(1):39. Epub 2022 May 19.

Division of Infectious Diseases and Global Public Health, Department of Medicine, University of California San Diego, 9500 Gilman Drive, La Jolla, CA, 92093-0507, USA.

Enhancing astaxanthin yield in Phaffia rhodozyma: current trends and potential of phytohormones.

Appl Microbiol Biotechnol 2022 May 17. Epub 2022 May 17.

Institute of Chemical Engineering, Ural Federal University Named After the First President of Russia B.N. Yeltsin, Mira Street 28, 620002, Ekaterinburg, Russia.

Astaxanthin is an important ketocarotenoid with remarkable biological activities and high economic value. In recent times, natural astaxanthin production by microorganisms has attracted much attention particularly in pharmaceuticals, nutraceuticals, cosmetics, and food and feed industries. Though, currently, productivity is still low and has restricted scale-up application in the commercial market, microbial production of astaxanthin has enormous prospects as it is a greener alternative to the predominating chemical synthesis.

The association between caffeine intake and testosterone: NHANES 2013-2014.

Nutr J 2022 May 17;21(1):33. Epub 2022 May 17.

Department of Urology, Stanford University School of Medicine, Stanford, CA, 94305, USA.

Background: Caffeine is one of the most commonly used psychoactive drugs in the world, and provides many health benefits including alertness, improved memory, and reducing inflammation. Despite these benefits, caffeine has been implicated in a number of adverse health outcomes possibly due to effects within the endocrine system, effects that may contribute to impaired reproductive function and low testosterone in men. Previous studies have investigated associations between caffeine consumption and testosterone levels in men, although the quantity and generalizability of these studies is lacking, and the results between studies are conflicting and inconclusive.
