Randomized response estimates for the 12-month prevalence of cognitive-enhancing drug use in university students.

2013

STUDY OBJECTIVE: To estimate the 12-month prevalence of cognitive-enhancing drug use. DESIGN: Paper-and-pencil questionnaire that used the randomized response technique. SETTING: University in Mainz, Germany. PARTICIPANTS: A total of 2569 university students who completed the questionnaire. MEASUREMENTS AND MAIN RESULTS: An anonymous, specialized questionnaire that used the randomized response technique was distributed to students at the beginning of classes and was collected afterward. From the responses, we calculated the prevalence of students taking drugs only to improve their cognitive performance and not to treat underlying mental disorders such as attention-deficit-hyperactivity diso…

Readiness to change among involuntarily and voluntarily admitted patients with substance use disorders

2019

AbstractBackgroundHealth care workers in the addiction field have long emphasised the importance of a patient’s motivation on the outcome of treatments for substance use disorders (SUDs). Many patients entering treatment are not yet ready to make the changes required for recovery and are often unprepared or sometimes unwilling to modify their behaviour. The present study compared stages of readiness to change and readiness to seek help among patients with SUDs involuntarily and voluntarily admitted to treatment to investigate whether changes in the stages of readiness at admission predict drug control outcomes at follow-up.MethodsThis prospective study included 65 involuntarily and 137 volu…

Ultrastructural pathology in emetine-induced myopathy

1988

Progressive myopathy developed in two women who consumed ipecac syrup containing emetine hydrochloride to induce vomiting as part of their anorexia nervosa. Muscle biopsy specimens were characterized by severe disruption of the sarcomeres. The ultrastructural spectrum extended from "Z-band streaming" to the formation of cytoplasmic bodies and also comprised abnormalities of the sarcotubular system, thus suggesting that muscle weakness may be related to both sarcomeric and sarcotubular lesions in this self-inflicted myopathy. It is tempting to suggest that muscle weakness may be correlated with or based on the pathology in sarcomeres and the sarcotubular system. As the myopathy is clinically…

Group treatment for substance use disorder in adults: A systematic review and meta-analysis of randomized-controlled trials

2019

Abstract Background and aims From residential programs to outpatient services, group therapy permeates the clinical field of substance misuse. While several group interventions for substance use disorders (SUDs) have demonstrated effectiveness, the existing evidence on group therapy has not been systematically reviewed. The current meta-analysis aims to provide estimates of the efficacy of group therapy for SUDs in adults using rigorous methods. Methods We included studies comparing group psychotherapy to no treatment control groups, individual psychotherapy, medication, self-help groups, and other active treatments applying no specific psychotherapeutic techniques for patients with substan…

The Association between Dietary Habits, Substance Use, and Mental Distress among Adults in Southern Norway: A Cross-Sectional Study among 28,047 Adul…

2021

The aim of the present study was to examine associations between dietary habits, substance use, and mental distress among adults. This cross-sectional study was conducted in 2019 using an online questionnaire and included 28,047 adults (≥18 years) from Southern Norway. Multivariable logistic regression models stratified by gender were used to examine the associations between different lifestyle behaviors and mental distress. The results showed increased odds of mental distress among males and females with low consumption of vegetables (OR:1.26

PSYCHIATRIC DISTURBANCE LEADING TO POTASSIUM DEPLETION, SODIUM DEPLETION, RAISED PLASMA-RENIN CONCENTRATION, AND SECONDARY HYPERALDOSTERONISM

1968

Abstract Nine psychiatrically disturbed women were studied, variously suffering from the effects of anorexia nervosa, vomiting, and abuse of diuretics and purgatives. Each had more than one source of electrolyte depletion, and each deliberately concealed at least one of these. All were potassium-depleted, and in all but one sodium depletion was also evident. During exacerbations plasma-renin concentration was raised, secretion-rate and plasma concentration of aldosterone were increased, and the metabolic clearance of aldosterone was diminished. It is suggested that in combined sodium and potassium deficiency, conservation of sodium may be relatively more effective than that of potassium, an…

An investigation of the stability of free and glucuronidated 11-nor-delta9-tetrahydrocannabinol-9-carboxylic acid in authentic urine samples.

2004

Preanalytical stability of a drug and its major metabolites is an important consideration in pharmacokinetic studies or whenever the analyte pattern is used to estimate drug habits. Firstly, the stability of free and glucuronidated 11-nor-delta9-tetrahydrocannabinol-9-carboxylic acid (THCCOOH, THCCOOglu) in authentic urine samples was investigated. Random urine samples of cannabis users (n = 38) were stored at -20, 4, and 20 degrees C up to 15 days and up to 5 days at 40 degrees C, and alterations of the analyte pattern during storage were followed by liquid chromatography-tandem mass spectrometry. Secondly, the influence of pH (range 5.0-8.0) on the stability of the analytes was studied us…

Meet–Test–Treat for HCV management: patients’ and clinicians’ preferences in hospital and drug addiction services in Italy

2022

Abstract Background It has been estimated that the incidence of chronic hepatitis C virus (HCV) will not decline over the next 10 years despite the improved efficacy of antiviral therapy because most patients remain undiagnosed and/or untreated. This study aimed to investigate the opinion of relevant target populations on the practicability, effectiveness and best modalities of the test-and-treat approach in the fight against HCV in Italy. Methods A survey was delivered to patients with HCV from the general population, patients from drug addiction services, hospital physicians and healthcare providers for drug addiction services. Results For both hospital clinicians and SerD HCPs, tolerabil…

Effects of a brief pre‑admission telephone reminder on no‑show and dropout rates in substance use disorder treatment: a quasi‑experimental study

2022

Abstract Background Appointment no-show and early dropout from treatment represent major challenges in outpatient substance use disorder treatment, adversely affecting clinical outcomes and health care productivity. In this quasi-experimental study, we examined how a brief reminder intervention for new patients before their first appointment affected treatment participation and retention. No-shows (not attending any sessions) and dropouts (discontinuation of initiated treatment because of three consecutively missed appointments) were compared between a period with pre-admission telephone calls (intervention) and a period without such reminders (non-intervention). Methods Participants were a…
