Filter by:This randomized controlled study compares tapering of long-term opioid therapy in a population with chronic non-cancer pain with control group constituted of waiting list. Half of participants receives intervention at baseline and the other half are controls but receives intervention after 4 months. Ethical approval to follow up excluded participants denying tapering at baseline.
Evidence suggests that repeated or chronic ketamine use, as compared to acute ketamine users, posed a higher clinical risk of developing psychotic disorders, potentially related to the underlying chronic N-methyl-D-aspartate receptor (NMDAR) dysfunction, and a higher risk of suffering from schizophrenia particularly in those genetically susceptible, or genetically predisposed ketamine abusers. With ketamine infusion rises as a emerging hope as an acute treatment for depression and suicidality under the shadow of unknown longer term psychotomimetic effects peculiarly amongst repeated or chronic use, the current case-control study aims to investigate: a) if repeated or chronic ketamine use is associated with an increased risk of psychosis by comparing those ketamine abusers with and without psychosis, and to those non-ketamine-using drug abusers with psychosis; and b) if genetic predisposition from single nucleotide polymorphisms are associated with risk of psychosis in ketamine abusers.
Substance abuse remain critical problems in both developed and developing countries. Under privileged communities where health and economic system is weakest, use of drugs and illicit substances starts during adolescence and young adulthood. This not just affect physical development, mental health and social integration, but also family formation and stability, deviant behaviour, sexual behaviour and involvement, educational pursuits, livelihood pursuits. Therefore, emphasises the need for preventive education at this impressionable age.
The primary aim of this project is to use a randomized single-blind sham-controlled study to investigate if high frequency repetitive transmagnetic stimulation (HF-rTMS) can modulate cue-induced craving in adult methamphetamine (METH) users. The investigators hypothesize that HF-rTMS directed at left dorsolateral prefrontal cortex (DLPFC) will result in a reduction in craving for METH compared to sham-controlled rTMS in adults with methamphetamine use disorder (MUD) as evidenced by validated measures of METH craving. Neurobiologically, the investigators anticipate rTMS mediated stimulation of the DLPFC could result in inhibition of cue-induced craving through potential disruption of involved circuitry. The current project proposes that participants who are recently abstinent from METH will be randomized into four experimental groups to provide two rTMS conditions (real versus sham) and two picture cues conditions (METH versus neutral). The experiment will have an induction phase where each subject will receive 10 daily treatments within 2 weeks. Just before each rTMS/sham session participants will be shown visual cues (METH or neutral). Participants will then undergo a maintenance phase for an additional month with assessments to evaluate craving and relapse. Urine samples for urine drug screening (UDS) will be collected at screening day and on days 1, 5 and 10. Just before each rTMS/sham session participants will be shown visual cues (METH and neutral). VAS craving scores will be assessed before and after picture presentation and after the rTMS/sham session. Before the first and 10th treatment session, participants were evaluated by the the Stimulant Craving Questionnaire (STCQ) and the Severity of Dependence Scale (SDS) questionnaires. Participants will then undergo a maintenance phase for an additional month. During the first week of maintenance, three rTMS/sham sessions will be administered. During each of the following 3 weeks, one rTMS/sham session will be given per week. As with the induction phase, urine samples will be collected for screening and STCQ and the SDS questionnaires will be completed at each maintenance session. To evaluate the long-term effects of the rTMS treatment, the investigators plan on contacting participants 6 months after treatment termination for all subjects who completed the 10 treatment sessions. During that phone conversation, craving and relapse will again be assessed.
In recent years adolescent substance abuse is a serious and growing problem. Substance use among adolescents means the use of alcohol, opiates, amphetamines, inhalants, cocaine, marijuana, benzodiazepines, hallucinogens, and anabolic steroids. The United Nations Office on Drugs and Crime reports that approximately 5% of the world's population used an illicit drug in 2010 and it is estimated that heroin, cocaine and other drugs are responsible for 0.1 to 0.2 million deaths per year. There is a limited number of studies in the literature that investigate the relationship between substance use disorder and respiratory functions. In Taylor et al., study reported that the proportion of cannabis-dependent study members with an FEV1/FVC ratio of, 80% was 36% compared to 20% for non-smokers. Another research of Taylor et al., in longitudinal observations over 8 years in young adults (cannabis smoking on lung function in young adults between the ages of 18 and 26) revealed a dose-dependent relationship between cumulative cannabis consumption and decline in FEV1/VC. In a monograph, stated that follow-up studies of regular cannabis-only smokers also found impaired respiratory function and pathological changes in lung tissue like those preceding the development of chronic obstructive pulmonary disease . The core anatomically described as a box, with the abdominals at the front, spinal and gluteal muscles at the back, the diaphragm on the top, and the pelvic floor and hip muscles on the bottom. Correct breathing is vital to abdominal training because respiratory muscles are directly involved during common core stability exercises. Moreover, the diaphragm, a component of core stability, plays a role in respiration and trunk stability by controlling intra-abdominal pressure . Oh et al.reported that, 30-min, 3 days a week for 8 weeks lumbar stabilization exercise had a more positive effect on pulmonary function than general physical therapy on stroke patients. Our hypothesis was that core exercises may positive effect on respiratory functions and functional capacity of substance use disorder individuals. The aim of our study is to investigate the effects of core exercises on respiratory functions and functional capacity in adolescents with substance use disorder.
The main purpose of the CoDISEN cohort study is to propose a model of prevention and care for HIV and viral hepatitis adapted to the needs of people who inject drugs (PWID) in Dakar, Senegal.
The goal of this research program is to implement and evaluate complementary interventions designed to address underage alcohol, marijuana, tobacco and other drug use and abuse among Native American youth residing in and around nine contiguous Indian reservations in rural portions of a Southern California county. Component 1. Motivational Interviewing (MI) Evaluations (Identified PHI). Approximately 150 participants between 13 and 20 years of age will participate in the Motivational Interviewing (MI) intervention and one follow-up assessment over an 18 month period. Questionnaires of youth substance use and access patterns will be by phone or self-administered using paper, iPad, and web-based surveys. Formal informed consent from participants 18 and older and assent and parental/legal guardian consent will be obtained from those participants under 18. Component 2. Psychoeducation (PE) Evaluations (Identified PHI). Approximately 150 participants between 13 and 20 years of age will participate in the Psychoeducation (PE) intervention and one follow-up assessment over an 18 month period. Questionnaires of youth substance use and access patterns will be by phone or self-administered using paper, iPad, and web-based surveys. Formal informed consent from participants 18 and older and assent and parental/legal guardian consent will be obtained from those participants under 18.
This study utilizes a Hybrid Type 1 multi-arm parallel group randomized control design to compare the effectiveness of an evidence-based treatment (CETA) delivered either in-person or via telephone, compared with a treatment as usual (TAU) control group, on improving adolescent and young adult (AYA) mental and behavioral health outcomes. The study will also gather information on counselor treatment knowledge, fidelity and competency following a technology-delivered training. Lastly, the cost associated with these strategies will be explored to inform future scale-up of training and services. This study will be conducted in Lusaka, Zambia and participants will be enrolled at four different levels: prospective CETA trainers, prospective CETA counselors, AYA clients, and research/organizational staff. AYA clients are the primary participant type.
The purpose of this research is to improve the ability of primary medical staffs in screening and intervention for alcohol, benzodiazepines, and other illicit drug use.
Background: Relapse is very common in patients with illicit drug use disorder and contributes to a series of bad consequences that substantially impact patients' physical and social functions. Due to the limited existence of effective addiction treatment, the majority of patients with drug use disorder could not access help when needing. Mobile health (mHealth) offers a potential solution to improving recovery outcome for patients in community. Objective: This paper is a protocol for a randomized controlled trial (RCT) of a smart phone application called community-based addiction rehabilitation electronic system (CAREs) . This interactive system consists of an APP for clients and a webpage for service providers, with the aim of teaching clients craving and emergency coping skills and helping service providers to improve work efficiency and effectiveness in community. Methods: A randomized controlled trial(RCT) will be conducted. Sixty drug illicit users who are newly ordered to undergo community rehabilitation will be recruited from the community in Shanghai. Participants will be 1:1 randomly assigned to receive integrated community rehabilitation by using CAREs or only receiving routine community rehabilitation for 6 months. Corresponding anti-drug social workers will provide service and monitor participants' drug use behavior in accordance with the routine work-flow. Outcomes will be assessed at baseline and in the 6th month. The primary study outcome is the performance on illicit drug urine test which will be carried on regularly twice per week during the study period. Secondary study outcomes include days that participants interact with anti-drug social workers, and the decrease rate of addiction-related issues severity index.
