RESUMO

BACKGROUND AND AIMS: Recovery management checkups (RMC) have established efficacy for linking patients to substance use disorder (SUD) treatment. This study tested whether using RMC in combination with screening, brief intervention, and referral to treatment (SBIRT), versus SBIRT alone, can improve linkage of primary care patients referred to SUD treatment. DESIGN: A randomized controlled trial of SBIRT as usual (n = 132) versus SBIRT plus recovery management checkups for primary care (RMC-PC) (n = 134) with follow-up assessments at 3 months post-baseline. SETTING: Four federally qualified health centers in the United States serving low-income populations. PARTICIPANTS: Primary care patients (n = 266, 64% male, 80% Black, mean age, 48.3 [range, 19-53]) who were referred to SUD treatment after SBIRT. INTERVENTIONS: SBIRT alone (control condition) compared with SBIRT + RMC-PC (experimental condition). MEASUREMENT: The primary outcome was any days of SUD treatment in the past 3 months. Key secondary outcomes were days of SUD treatment overall and by level of care, days of alcohol and other drug (AOD) abstinence, and days of using specific substances, all based on self-report. FINDINGS: At 3-month follow-up, those assigned to SBIRT + RMC-PC (n = 134) had higher odds of receiving any SUD treatment (46% vs 20%; adjusted odds ratio = 4.50 [2.49, 8.48]) compared with SBIRT only, including higher rates of entering residential and intensive outpatient treatment. They also reported more days of treatment (14.45, vs 7.13; d = +0.26), more days abstinent (41.3 vs 31.9; d = +0.22), and fewer days of using alcohol (27.14, vs 36.31; d = -0.25) and cannabis (19.49, vs 28.6; d = -0.20). CONCLUSIONS: Recovery management checkups in combination with screening, brief intervention, and referral to treatment are an effective strategy for improving linkage of primary care patients in need to substance use disorder treatment over 3 months.

RESUMO

Background: Mortality from non-small cell lung cancer (NSCLC) has improved with screening and novel treatments. The substance use epidemic has threatened health outcomes in a variety of diseases, but little is known about how it is associated with NSCLC outcomes. Methods: We performed a retrospective cohort study of 211 patients with NSCLC treated at a safety-net hospital. Sociodemographic data and clinical outcomes were extracted via review of electronic medical records. Patients were stratified based on substance use status. Comparative and multivariable analyses were performed to evaluate baseline characteristics and lung cancer outcomes including survival. Results: Among 193 patients (91.5%) with information available on substance use, 24.9% reported substance use; specifically, alcohol, marijuana, and illicit substances. Patients with substance use were more likely to have increased health care utilization and poor social determinants of health, including safe housing, stable employment, and social support. There were no significant differences in treatment adherence. Only 6.3% of patients with substance use did not receive guideline concordant care (GCC) compared to 24.8% of patients without substance use; due to poor performance status, increased comorbidities, or loss to follow up. On univariable analysis, patients with substance use experienced inferior median overall survival (OS) if they had metastatic disease (0.40 vs. 1.03 years, P=0.01). However, in the multivariable analysis, substance use did not predict for survival. Independent predictors of mortality were sex (male HR, 1.67; 95% CI: 1.04-2.68; P=0.04), smoking status (current smoking HR, 2.63; 95% CI: 1.14-6.08; P=0.02), and stage (stage IV HR, 14.96; 95% CI: 6.28-35.63; P=0.008). Conclusions: Substance use is associated with poor social determinants of health and increased health care utilization. On multivariable analysis, substance use was not independently associated with OS once guideline-concordant care was used. Future studies should focus on improving our understanding of these associations, delineating potential mechanisms, and developing evidence-based strategies to reduce health care utilization and overcome challenges related to poor social determinants of health.

RESUMO

Juvenile Drug Treatment Courts (JDTC) emerged in the mid-1990s as a potential solution to concern about substance use among youth in the juvenile justice system (JJS). Despite substantial research, findings on the JDTC effectiveness for reducing recidivism and substance use remain inconsistent, hampered by methodological problems. In 2016, the Office of Juvenile Justice and Delinquency Prevention published research-based JDTC Guidelines for best practices, and funded technical assistance for implementation and a multisite national outcomes study among JDTCs implementing the Guidelines. Ten sites were originally selected for this study, with a JDTC and Traditional Juvenile Court (TJC) participating. In two sites, moderate- to high-risk youth were randomized to JDTC or TJC, and in eight sites, a regression discontinuity design assigned moderate- to high-risk youth to JDTC, and other youth to TJC. Findings from four sites with sufficient cases and follow-up rates indicated that JDTCs reduced cannabis use, increased access to mental health services, and reduced recidivism. However, the effects were small to moderate, with positive impacts mainly observed among high-risk youth. The impacts of JDTCs may have been attenuated because Guidelines implementation was inconsistent across courts, and some TJCs implemented elements of the Guidelines, blurring the distinction between JDTCs and TJCs.

RESUMO

AIMS: Cannabis use disorder (CUD) and depression frequently co-occur in youth. How depressive symptoms change over the course of CUD treatment and how they impact substance use treatment outcomes is unknown. In the current study, we examine the temporal relationships between cannabis use and depression in adolescents receiving evidence-based treatments for CUD as part of a multisite clinical trial. DESIGN: Six hundred adolescents (age 12-18) with a CUD were randomly assigned to substance use treatment from one of five evidence-based psychosocial interventions. We assessed self-reported cannabis use frequency and depressive symptoms at baseline (BL) and again at 3-, 6-, 9, and 12-months. A bivariate latent change model assessed bidirectional effects of baseline levels and time-lagged changes in depressive symptoms and cannabis use on depression and cannabis use outcomes. FINDINGS: Depressive symptoms (72%) and major depressive disorder (MDD) (18%) were common at BL. Both depression and cannabis use decreased over time and change in cannabis use was significantly associated with change in depressive symptoms (b = 1.22, p = .003). Time-lag analyses showed that within-subject change in depression (from one time point to the next) was predicted by previous depression (b = -0.71, p < .001) but not cannabis use (p = .068), and change (decrease) in cannabis use was predicted by previous (greater) depressive symptoms (b = -1.47, p < .001) but not cannabis use (p = .158), respectively. CONCLUSION: These findings indicate an enduring relationship between decreasing cannabis use and decreasing depression among adolescents lasting for 9-months after receiving psychosocial interventions for CUD. The presence of depressive symptoms did not appear to interfere with substance use treatment or attenuate improvements in cannabis use frequency. A decrease in cannabis use was not contingent upon a reduction in depressive symptoms. These findings are limited by the possibility of regression to the mean for both cannabis use and depressive symptoms, and the lack of a nonintervention control group.

RESUMO

BACKGROUND: This retrospective analysis describes the prevalence of and risk factors associated with the development of hypocalcemia in patients with cancer receiving bone-modifying agents (BMAs) as supportive care. PATIENTS AND METHODS: Patients with cancer treated with an intravenous or subcutaneous BMA, including pamidronate, zoledronic acid, or denosumab, at a tertiary care/safety net hospital in 2005 through 2015 were included in this retrospective review. We reviewed the medical records for predictive clinical and laboratory parameters and for patient outcomes. RESULTS: A total of 835 patients with cancer received at least one dose of a BMA during the specified time frame; 205 patients (25%) developed hypocalcemia of CTCAE grade ≥1 within 8 weeks of BMA initiation, 18 of whom (8.8%) had grade ≥3, and 3 patients died as a result. Multivariate analysis showed that patients with hematologic malignancy (odds ratio [OR], 1.956; P=.025), bone metastases (OR, 2.443; P=.017), inpatient status (OR, 2.592; P<.001), and deficient baseline vitamin D levels (OR, 2.546; P<.023) were more likely to develop hypocalcemia. Hypercalcemia before BMA administration (OR, 0.474; P=.032) was protective. CONCLUSIONS: Certain patient populations, including those with hematologic malignancies and/or bone metastases, warrant closer monitoring of calcium levels while receiving BMAs because of the high rate of hypocalcemia. Low pretreatment vitamin D levels are associated with the development of hypocalcemia. These data support close monitoring of calcium levels in patients with cancer receiving BMAs, in addition to adequate repletion of vitamin D before initiation of BMAs when possible.

RESUMO

Background: During 2007-2008, media attention focused on a cluster of youth suicides in the UK. There were two peaks (P1, P2) in the volume of newspaper reporting of the deaths. The number of possible suicides was greater than expected at the time of the first peak but not at the time of the second. Aims: To explore any differences in the content of the reporting peaks and to consider implications for imitation and prevention. Method: A content analysis of two peaks of newspaper reporting was conducted. Results: There were 204 articles in P1 (December 27, 2007 to February 19, 2008) and 157 in P2 (February 20, 2008 to March 15, 2008). Four main themes were identified: individual stories; possible causes; features of reporting of the cluster; and educating and informing the public. P1 articles more frequently contained: explicit details of method; photographs of the deceased, and contained more characterization of individuals. Limitations: The focus was on print media, future studies should incorporate online and social media content. Conclusion: The findings provide some support for the hypothesis of a process of suggestion initiated by sensationalist reporting in P1. This contributes to the evidence base of the role of the press in suicide imitation and prevention, highlighting the importance of care when reporting suicides.

RESUMO

A marked delay in the electrical repolarization of heart ventricles is characterized by prolongation of the Q-T wave (QT) interval on a surface electrocardiogram. Such a delay can lead to potentially life-threatening cardiac arrhythmia (torsades de pointes). Such prolongation is also a widely accepted cardiac safety biomarker in drug development. Current preclinical drug-safety assays include patch clamp analysis to evaluate drug-related blockade of cardiac repolarizing ion currents. Recently reported patch clamp assay results have shown predictive sensitivities and specificities in the ranges of 64%-82% and 75%-88%, respectively. In this project, we use a support vector machine classifier to find mean sensitivities and specificities of 85% and 90%, respectively, across 77 drug subclassifications. Clustering by gene expression profile similarities shows that drugs known to prolong the QT interval do not always form distinct groups, but the number of groups is limited. The most common biological network links associated with these groups involve genes linked with fatty acid metabolism, G proteins, intracellular glutathione, immune responses, apoptosis, mitochondrial function, electron transport, and mitogen-activated protein kinases. These results suggest that machine-learning analysis of gene expression and clustering may augment cardiac safety predictions for improving drug-safety assessments.

RESUMO

Resistance to insulin action is a key cause of diabetic complications, yet much remains unknown about the molecular mechanisms that contribute to the defect. Glucose-induced insulin resistance in peripheral tissues such as the retina is mediated in part by the hexosamine biosynthetic pathway (HBP). Glucosamine (GAM), a leading dietary supplement marketed to relieve the discomfort of osteoarthritis, is metabolized by the HBP, and in doing so bypasses the rate-limiting enzyme of the pathway. Thus, exogenous GAM consumption potentially exacerbates the resistance to insulin action observed with diabetes-induced hyperglycemia. In the present study, we evaluated the effect of GAM on insulin action in retinal Müller cells in culture. Addition of GAM to Müller cell culture repressed insulin-induced activation of the Akt/mTORC1 signaling pathway. However, the effect was not recapitulated by chemical inhibition to promote protein O-GlcNAcylation, nor was blockade of O-GlcNAcylation sufficient to prevent the effects of GAM. Instead, GAM induced ER stress and subsequent expression of the protein Regulated in DNA Damage and Development (REDD1), which was necessary for GAM to repress insulin-stimulated phosphorylation of Akt on Thr308. Overall, the findings support a model whereby GAM promotes ER stress in retinal Müller cells, resulting in elevated REDD1 expression and thus resistance to insulin action.

RESUMO

BACKGROUND: There has been continuing change in the nature of care homes in the UK with 80 % of residents now living with some form of dementia or memory problem. Caring in this environment can be complex, challenging and stressful for staff; this can affect the quality of care provided to residents, lead to staff strain and burnout, and increase sickness, absence and turnover rates. It is therefore important to find interventions to increase the wellbeing of staff that will not only benefit staff themselves but also residents and care providers. Mindfulness training is known to be effective in treating a variety of physical and mental health conditions. METHODS AND DESIGN: The study uses mixed methods centred on a stepped-wedge cluster randomised trial. Thirty care homes in Wales are implementing a brief web-based mindfulness training course, starting in random sequence. Four to ten consenting staff from each facility undertake the course and complete validated questionnaires at baseline and after eight and 20 weeks. We shall also interview a stratified sample of ten trained staff and analyse the transcripts thematically. The primary outcome is stress; secondary outcomes include job satisfaction, attitudes towards residents and sickness absence rates. DISCUSSION: With increasing numbers of people living with dementia in care homes and causing stress in their carers, it is important to evaluate support strategies for staff. Mindfulness-based therapies may be of potential benefit and need detailed examination. TRIAL REGISTRATION: ISRCTN registry. ISRCTN80487202. Registered 24 July 2013.

RESUMO

OBJECTIVES: To determine the added risk of opioid problem use (OPU) in youth with marijuana/alcohol problem use (MAPU). METHODS: A total of 475 youth (ages 14-21 years) with OPU + MAPU were compared to a weighted sample of 475 youth with MAPU only (i.e. no OPU) before and after propensity score matching on gender, age, race, level of care and weekly use of marijuana/alcohol. Youth were recruited from 88 drug treatment sites participating in eight Center for Substance Abuse Treatment-funded grants. At treatment intake, participants were administered the Global Appraisal of Individual Need to elicit information on demographic, social, substance, mental health, human immunodeficiency virus (HIV), physical and legal characteristics. Odds ratios with confidence intervals were calculated. RESULTS: The added risk of OPU among MAPU youth was associated with greater comorbidity; higher rates of psychiatric symptoms and trauma/victimization; greater needle use and sex-related HIV risk behaviours; and greater physical distress. The OPU + MAPU group was less likely to be African American or other race and more likely to be aged 15-17 years, Caucasian; report weekly drug use at home and among peers; engage in illegal behaviors and be confined longer; have greater substance abuse severity and polydrug use; and use mental health and substance abuse treatment services. CONCLUSIONS: These findings expand upon the existing literature and highlight the substantial incremental risk of OPU on multiple comorbid areas among treatment-seeking youth. Further evaluation is needed to assess their outcomes following standard drug treatment and to evaluate specialized interventions for this subgroup of severely impaired youth.

RESUMO

OBJECTIVE: The objective is to identify whether single 20 min massage sessions were safe and effective in reducing stress levels of isolated haematological oncology patients. DESIGN: Based on a randomised controlled trial, 39 patients were randomised to aromatherapy, massage or rest (control) arm. MEASURES: The measures were serum cortisol and prolactin levels, quality of life (EORTC QLQ-C30) and semi-structured interviews. Primary outcome measure was the fall in serum cortisol levels. RESULTS: A significant difference was seen between arms in cortisol (P=0.002) and prolactin (p=0.031) levels from baseline to 30 min post-session. Aromatherapy and massage arms showed a significantly greater drop in cortisol than the rest arm. Only the massage arm had a significantly greater reduction in prolactin then the rest arm. The EORTC QLQ-C30 showed a significant reduction in 'need for rest' for patients in both experimental arms compared with the control arm, whereas the semi-structured interviews identified a universal feeling of relaxation in patients in the experimental arms. CONCLUSION: This pilot study demonstrated that in isolated haematological oncology patients, a significant reduction in cortisol could be safely achieved through massage, with associated improvement in psychological well-being. The implications are discussed.

RESUMO

AIMS: This study compared assertive continuing care (ACC) to usual continuing care (UCC) on linkage, retention and a measure of continuing care adherence. Outcome analyses tested the direct and indirect effects of both conditions and level of adherence on early (months 1-3) and longer-term (months 4-9) abstinence. DESIGN: Two-group randomized design. SETTING: Eleven counties surrounding a community-based residential treatment program in the Midwestern section of the United States. PARTICIPANTS: A total of 183 adolescents, ages 12-17 years, with one or more Diagnostic and Statistical Manual version IV (DSM-IV) substance use dependence disorder and met American Society for Addiction Medicine (ASAM) placement criteria for non-medical residential treatment. INTERVENTION: Prior to discharge from residential treatment, participants were assigned randomly to receive either UCC, available at outpatient clinics in the 11-county study area, or ACC via home visits. MEASUREMENTS: Self-reported interview data were collected at intake, 3, 6 and 9 months post-residential discharge. Urine test data and interviews with a caregiver were conducted at baseline and 3 months. FINDINGS: ACC led to significantly greater continuing care linkage and retention and longer-term abstinence from marijuana. ACC resulted in significantly better adherence to continuing care criteria which, in turn, predicted superior early abstinence. Superior early abstinence outcomes for both conditions predicted longer-term abstinence. CONCLUSIONS: ACC appears to be an effective alternative to UCC for linking, retaining and increasing adherence to continuing care. Replication with larger samples is needed to investigate further the direct and indirect effects of ACC found in this study

RESUMO

Though widely used and presumed effective in practice, some scholars (Dishion et al., 1999) have raised the concern that group therapy for adolescents with substance use disorder and a range of deviancy has the potential for causing iatrogenic effects (e.g., increased substance use, behavior and legal problems) for those with low deviancy. Using data from 400 youth in the largest adolescent treatment experiment conducted to date (Dennis et al., 2004), this study shows that group composition in terms of conduct disorder symptoms is not associated with worse substance use, psychological, environmental or legal treatment outcomes. The results actually indicated that there was a slight advantage for youth with high conduct disorder to be included in the groups with less symptoms. The results appear consistent with recent meta-analyses of delinquency studies (Lipsey, 2006) which have found no evidence of iatrogenic effects. These results support the common clinical belief that group therapy for youths with substance use disorders is a safe and effective treatment modality.

RESUMO

The association of early alliance to treatment attendance and longitudinal outcomes were examined in 356 adolescents participating in a randomized clinical trial targeting cannabis use. Both patient and therapist views of alliance were examined, and outcomes were evaluated over 12 months after numerous other sources of variance were controlled. Patient-rated alliance predicted a reduction in cannabis use at three and six months and a reduction in substance-related problem behaviors at six months. Therapist-rated alliance did not predict outcomes. Neither patient nor therapist alliance ratings were associated with attendance. The findings support the important and often overlooked role that alliance can play in treating substance abusing, often delinquent, adolescents.

RESUMO

Reconciling urine results and self-reports is a classic challenge in substance abuse treatment research in general. For adolescents, the problems are compounded by the facts that they are more likely to use marijuana (which takes longer to metabolize) and to be coerced into treatment (which may increase lying). This article examines the construct and predictive validity of several different approaches for combining urine and self reported drug use including using common individual measures (urine tests and self-reported recency, frequency, and peak use), taking either as positive, using a summary scale, and using a latent model. Data are from 819 older adolescents 24 to 42 months after intake in seven sites. Days of use, the GAIN's substance frequency scale, and a latent model were the three best methods in terms of construct and predictive validity. Implications for treatment and longitudinal evaluation will be discussed.

RESUMO

Because alcohol or other drug use following adolescent substance abuse treatment is common, understanding mediators of posttreatment outcome could help improve treatment interventions. The authors conducted path analyses based on data from 552 adolescents (aged 12-18; 82% male) with cannabis abuse or dependence who participated in outpatient treatment. The analysis used the Family Conflict and Cohesion subscales, from the Family Environment Scale, and several scales and indices from the Global Appraisal of Individual Needs. Family conflict, family cohesion, and social support indirectly predicted substance use and substance-related problems as mediated by recovery environment and social risk. This model replicated across 4 follow-up waves (3, 6, 9, and 12 months postintake). These results support the idea of targeting environmental factors during continuing care as a way to improve treatment outcomes for adolescents with cannabis disorders.

RESUMO

While addiction is increasingly recognized as a chronic condition, little information is available on the actual duration of addiction and treatment careers. The purpose of this study was to estimate the duration and correlates of years between (a) first use and at least a year of abstinence and (b) first treatment admission and at least one year of abstinence. Data are from 1,271 of 1,326 (96%) people recruited from a stratified sequential sample of admissions to publicly funded treatment programs in a large metropolitan area. Participants were interviewed at 6, 18, 24, 36, 48, and 60 months post-intake. With an average age at the referent intake of 35 (SD = 8) years, the sample is 59% female, 87% African American, 7% Hispanic, and 5% white. The most common dependence diagnoses were for cocaine (64%), alcohol (44%), opioids (41%), and/or marijuana (14%). Using lifetime substance use and treatment histories collected at intake and subsequent treatment utilization recorded during follow-up interviews, we conducted survival analysis to estimate the time from first use and first treatment until people reported 12 months of abstinence or died (with people still using, in treatment, or dead at the last follow-up treated as right censored). During the three years after intake, 47% reached at least 12 months of abstinence. The median time from first to last use was 27 years. The median time from first treatment episode to last use was 9 years. Years to recovery were significantly longer for males, people starting use under the age of 21 (particularly those starting under the age of 15), people who had participated in treatment 3 or more times, and for people high in mental distress. The exploratory results suggest that multiple episodes of care over several years are the norm and that rather than thinking of multiple episodes in terms of "cumulative dosage," it might be better thought of as further evidence of chronicity and that we need to develop and evaluate models of longer term recovery management.

RESUMO

Recombinant modified vaccinia virus Ankara (MVA) is together with a few other attenuated viral vectors on the forefront of human immunodeficiency virus type 1 (HIV-1) vaccine development. As such, MVA-vectored vaccines are likely to be administered into immunocompromized individuals. Here, we demonstrated in a good laboratory practice study safety and biological clearance of candidate HIV-1 vaccine MVA.HIVA in simian immunodeficiency virus (SIV)-infected rhesus macaques and mice with a severe combined immunodeficiency (SCID) following an intradermal vaccine administration. In SIV-infected macaques, MVA.HIVA DNA was undetectable by nested PCR 6 weeks after dosing. In SCID mice, the MVA.HIVA vaccine was well tolerated and a positive PCR signal was only observed at the site of injection 49 days after dosing in four out of six mice, but even these sites were negative by day 81 post-injection. Therefore, the MVA.HIVA vaccine is considered safe for application in phase I clinical trials in HIV-1-infected human subjects. These results also contribute to the confidence of using MVA as a smallpox vaccine.

RESUMO

This article presents the main outcome findings from two inter-related randomized trials conducted at four sites to evaluate the effectiveness and cost-effectiveness of five short-term outpatient interventions for adolescents with cannabis use disorders. Trial 1 compared five sessions of Motivational Enhancement Therapy plus Cognitive Behavioral Therapy (MET/CBT) with a 12-session regimen of MET and CBT (MET/CBT12) and another that included family education and therapy components (Family Support Network [FSN]). Trial II compared the five-session MET/CBT with the Adolescent Community Reinforcement Approach (ACRA) and Multidimensional Family Therapy (MDFT). The 600 cannabis users were predominately white males, aged 15-16. All five CYT interventions demonstrated significant pre-post treatment during the 12 months after random assignment to a treatment intervention in the two main outcomes: days of abstinence and the percent of adolescents in recovery (no use or abuse/dependence problems and living in the community). Overall, the clinical outcomes were very similar across sites and conditions; however, after controlling for initial severity, the most cost-effective interventions were MET/CBT5 and MET/CBT12 in Trial 1 and ACRA and MET/CBT5 in Trial 2. It is possible that the similar results occurred because outcomes were driven more by general factors beyond the treatment approaches tested in this study; or because of shared, general helping factors across therapies that help these teens attend to and decrease their connection to cannabis and alcohol.
