Treatment of opioid use disorder often begins with brief intensive inpatient or outpatient programs. Given the high relapse rates following intensive treatment, it is important to determine factors that lead to success post-discharge. Incorporating assessment during and early post-discharge may help determine such factors. The current study evaluated changes in quality of life among individuals during and after discharge from inpatient and partial hospitalization opiate treatment programs. Participants (n?=?143) were recruited while in the programs and were re-assessed one month later (n?=?113). Results found improvements in quality of life and reductions in rates of opiate use at follow-up. Individuals with greater improvements in Health, Substance Use, and Emotional Health domains were less likely to have relapsed. Treatment utilization post-discharge was not associated with relapse. Findings emphasize the importance of measurement-based care and suggest the need to assess indicators of treatment success beyond rates of relapse. 相似文献
Background: Current guidelines regarding the use of intravenous morphine (IM) in the management of patients with acute decompensated heart failure (ADHF) are discordant; whereas the American guidelines reserve IM for terminal patients, the European guidelines recommend its use in the early stage of treatment. Our aim was to determine the impact of IM on outcomes of ADHF patients. Methods: Stepwise logistic regression and propensity score analysis of ADHF patients with and without use of IM was performed in a national heart failure survey. Results: Of the 4102 enrolled patients, we identified 2336 ADHF patients, of whom 218 (9.3%) received IM. IM patients were more likely to have acute coronary syndromes, acute rather than exacerbation of chronic heart failure, and diabetes mellitus and dyslipidemia. They had higher heart rate, were less likely to receive diuretics and more likely to receive aspirin and statins. Unadjusted in-hospital mortality rates were 11.5% versus 5.0% for patients who did or did not receive IM, and the adjusted odds ratio (OR) for in-hospital death was: 2.0 (1.1–3.5, P = 0.02). Using propensity analysis, we identified 218 matched pairs of patients who did or did not receive IM. In multivariable analysis accounting for the propensity score (c-statistic 0.82), IM was not associated with increased in-hospital death (OR: 1.2 (0.6–2.4), P = 0.55). Conclusion: IM was used sparingly in our ADHF cohort, and was independently associated with increased in-hospital death in multivariable analysis, but not in propensity score analysis. Thus, IM may be used in ADHF, but with caution. Further randomized trials are warranted. 相似文献
We studied the effects of opioid and adrenergic agonists and antagonists given systemically intravenously and intrathecally on postprandial antral and small bowel motility in a chronic conscious dog model. We studied eight dogs with a surgically implanted thoracic spinal intrathecal injection catheter, and six gastrointestinal manometric perfusion catheters. Morphine given intrathecally or intravenously induced propagated clusters of intestinal pressure activity in the fed dogs. The minimal effective dose for morphine was 150 g/kg by the intrathecal route and 450 g/kg by the intravenous route. ST-91 (an 2-adrenergic agonist) profoundly inhibited antral and small intestinal pressure activity with similar minimal effective dose (100 g/kg) and duration of effect for both intravenous and intrathecal routes. Neither naloxone (3000 g/kg) nor combined phentolamine (1500 g/kg) with propranolol (300 g/kg) altered postprandial antral or small intestinal motility. The capacity of pharmacologic agents to block morphine-induced activity fronts when administered in the same compartment (intravenously or intrathecally) was investigated. The minimally effective morphine-antagonist dose for naloxone was similar intrathecally and intravenously (36 g/kg for both routes). ST-91 (100 g/kg) when given intrathecally or intravenously blocked morphine-induced clustered phasic pressure activity while simultaneously abolishing postprandial small intestine phasic pressure activity. These data suggest the presence of opioid and 2-adrenergic receptors in the spinal cord that can modulate gastrointestinal motility in the postprandial state. Pharmacological interactions between these systems occur at spinal and target organ levels. 相似文献
Background: Research has demonstrated that patients with opioid use disorders (OUD; including both opioid abuse and/or dependence) have poorer neuropsychological functioning compared to healthy controls; however, the pattern and robustness of the findings remain unknown.
Objectives: This study meta-analyzed the results from previous research examining the neuropsychological deficits associated with opioids across 14 neurocognitive domains.
Method: Articles comparing patients with OUD to healthy controls were selected based on detailed inclusion/exclusion criteria and variables of interest were coded. In total, 61 studies were selected for the analyses. These consisted of 2580 patients with OUD and 2102 healthy control participants (15.9% female). Drug-related variables were analyzed as potential moderators.
Results: The largest effect size difference in neuropsychological performance was observed in complex psychomotor ability. With the exception of the motor and processing speed domains, which showed no group differences, small-to-medium effect sizes were associated with all neurocognitive domains examined. Meta-regression revealed that increases in the length of abstinence were associated with decreases in effect sizes of the complex psychomotor domain. Additionally, attentional ability predicted effect size differences in executive functioning as well as verbal memory ability. Although the majority of meta-analyzed studies demonstrated significant differences between patients with OUD and controls, the average raw scores for patients with OUD in these studies typically fell within the normal range.
Conclusion: The pattern of neuropsychological performance among patients with OUD appears to reflect mild generalized cognitive dysfunction, with a large effect in complex psychomotor abilities. 相似文献
AbstractBackground: Natural opiate users constitute a large proportion of opioid dependent individuals in India, and enjoy socio-cultural sanction in certain parts of the country. However, no study has assessed the pathways to care among this population in India.Objective: To assess the pathways to care among treatment-seeking natural opiate dependent individuals.Method: This cross sectional, explorative study was conducted at a tertiary care drug treatment centre located in North India. A total of 125 male participants aged >18?years, seeking treatment for natural opiate dependence from our outpatient clinic were included. A semi-structured proforma and WHO mental health encounter form was applied to assess socio-demographic, treatment details and pathways to care.Results: The mean age was 46.17 (±11.98) years. Poppy husk (phukki/doda/posht) was the most common primary natural opiate used (84%). First point of treatment contact was addiction psychiatrist (n?=?90; 72%) in majority. First time treatment seeking was either by self-referral (60.8%) or referral by relatives and friends (24.8%) with mean time lag of 18.63?years after the onset.Conclusion: Natural opiates dependent patients seek treatment late in the course of their illness, often directly from a tertiary addiction treatment centre. Barriers to seek treatment needs to be addressed. 相似文献
The major drug of abuse among teenagers in the United States continues to be ethanol (EtOH), but use is seen in children as
young as nine. In the studies reported here, the impact of EtOH on biologic and hormonal parameters of puberty was assessed
in female rats. Rats were fed a liquid diet containing EtOH, pair fed an identical liquid diet containing dextrimaltose instead
of EtOH, or fed a liquid diet not containing EtOH ad libitum. Feeding was started at 21, 25, or 28 d of age. EtOH markedly
delayed the age at vaginal opening (34.5±0.5 d in controls vs 48.5±2.4 d in EtOH animals; p<0.001), delayed the age at first estrous (40.9±0.6 d in controls vs 61.2±2.6 d in EtOH animals; p<0.001), increased the length of the estrous cycle, and decreased the number of proestrous days. EtOH, concomitant with reduced
ovarian and uterine weight, decreased serum estradiol and progesterone. Associated with these changes in ovarian hormones
there was a selective increase in follicle-stimulating hormone, but not luteinizing hormone. EtOH consistently reduced insulin-like
growth factor-1. In general, EtOH-induced disruption was more severe the younger the animals were at the start of feeding.
Opiate receptor blockade with naltrexone completely prevented the EtOH-induced delay in vaginal opening. The impact of EtOH
on female puberty is dramatic, is an emerging public health problem, and deserves more study. 相似文献
Aims To examine and compare mortality rates in patients treated with oral and implant naltrexone. Design A retrospective cohort study. Setting A community not‐for‐profit drug treatment clinic. Participants Patients treated with oral naltrexone (n = 2155, 17 207 patient‐years) and implant naltrexone (n = 2389, 11 678 patient‐years) for problematic opiate use between August 1997 and December 2009. Measurements Crude gender, age, treatment period and cause‐specific mortality rates were calculated using data obtained from the National Death Index. Findings Crude mortality rates for patients treated with oral naltrexone [8.78 deaths per 1000 patient‐years (ptpy), 95% confidence interval (CI): 7.38–10.17] were significantly different to those treated with implant naltrexone (6.59 ptpy, 95% CI: 5.13–8.06) (P = 0.0339). During the first 4 months following treatment, differences in the two groups were particularly apparent, with a mortality rate of 26.28 ptpy in patients treated with oral naltrexone compared to 7.34 ptpy in patients treated with implant naltrexone (P = 0.0003). Differences in initial mortality rates following treatment were associated predominantly with high rates of opiate overdoses in oral naltrexone patients during the first 4 months following treatment (17.22 ptpy compared with 0.67 ptpy in implant naltrexone patients) (P < 0.0001). Conclusions The use of implant naltrexone can reduce all‐cause mortality and opiate overdose during the first 4 months following treatment compared with patients treated with oral naltrexone. 相似文献
Confirmation or exclusion of recent heroin consumption is still one of the major challenges for forensic and clinical toxicologists. A great variety of biomarkers is available for heroin abuse confirmation, including various opium alkaloids (eg, morphine, codeine), street heroin impurities (eg, 6‐acetylcodeine [6‐AC], noscapine, papaverine) as well as associated metabolites (eg, 6‐monoacetylmorphine [6‐MAM], morphine glucuronides). However, the presence of most of these biomarkers cannot solely be attributed to a previous heroin administration but can, among other things, also be due to consumption of poppy seed products (‘poppy seed defense’), opium preparations or specific medications, respectively. A reliable allocation is of great importance in different contexts, for instance in the case of DUID (driving under the influence of drugs) investigations, in driving licence re‐granting processes, in workplace drug testing (WDT), as well as in post‐mortem identification of illicit opiate use. Additionally, differentiation between illicit street heroin abuse and pharmaceutical heroin administration is also important, especially within the frame of heroin‐assisted treatments. Therefore, analysis of multiple biomarkers is recommended when illicit opiate consumption is assumed to obtain the most reliable results possible. Beyond that, interpretation of positive opiate test results requires a profound insight into the great variety of biomarkers available and their validity regarding the alleged consumption. This paper aims to provide an overview of the wide variety of heroin abuse biomarkers described in the literature and to review them regarding their utility and reliability in daily routine analysis. 相似文献
