"You need to know that you are not alone": the sustainability of community-based dance programs for people living with Parkinson's disease.

Purpose: To identify factors contributing to the long-term sustainability of community-based dance programs for people living with Parkinson's disease in order to inform the design and development of sustainable programs.

Methods: Multi-site ethnographic fieldwork was conducted at four different preexisting dance programs for people living with Parkinson's disease. Dancer, facilitator, and community stakeholder perspectives were gathered via semi-structured interviews in order to create a deeper understanding of how existing programs navigate challenges and maintain stability.

Using theory knitting to conceptualize social phenomena in the design and evaluation of dance programs for people living with Parkinson's disease.

Dance programs for people living with Parkinson's disease (PwPD) offer participants an opportunity to exercise, engage in artistic self-expression, and form new relationships. While it is understood that the social dimension of dance programs for PwPD contributes to dancer satisfaction and program sustainability, the social mechanisms instrumental to program success are under-examined. Engaging with theory from wider disciplines, or "theory knitting" can help program designers and evaluators examine the mechanisms and contextual factors that make classes socially meaningful with greater detail and specificity.

Experiences of people living with Parkinson's disease and key stakeholders in dance-based programs: a systematic review and meta-ethnography.

Purpose: To identify and synthesize qualitative literature on the experiences of participants and key stakeholders in dance programs for people living with Parkinson's disease. Synthesizing the available literature can generate new insights into participant experience to inform current and future programs.

Materials And Methods: Qualitative and mixed methods studies were identified via a systematic search of six databases: CINAHL, Web of Science, Scopus, SPORTDiscus, PsycInfo, and MEDLINE.

Prevalence of Cannabidiol, ∆9- and ∆8-Tetrahydrocannabinol and Metabolites in Workplace Drug Testing Urine Specimens.

Given the recent popularity of cannabidiol (CBD) use and the emergence of ∆8-tetrahydrocannabinol (∆8-THC), the prevalence and concentrations of these and other cannabinoids were investigated in 2,000 regulated and 4,000 non-regulated specimens from workplace drug testing. All specimens were screened using liquid chromatography coupled to mass spectrometry (LC-MS-MS) for the presence of 7-hydroxy-CBD (7-OH-CBD) and ∆9-tetrahydrocannabinol-9-carboxylic acid (∆9-THC-COOH), with a cutoff of 2 ng/mL. Specimens screening positive by LC-MS-MS were analyzed by immunoassay at 20, 50 and 100 ng/mL cutoffs and by an LC-MS-MS confirmation method for 11 cannabinoids and metabolites with a 1 ng/mL cutoff.

Patterns of Cannabis Use Among Individuals with Obsessive-Compulsive Disorder: Results from an Internet Survey.

Background: Americans increasingly use cannabis, including those with psychiatric disorders. Yet little is known about cannabis use among individuals with obsessive-compulsive disorder (OCD). Thus, we conducted the first survey of cannabis users with OCD.
