RESUMEN

BACKGROUND: Individuals with minor ischaemic stroke and intracranial occlusion are at increased risk of poor outcomes. Intravenous thrombolysis with tenecteplase might improve outcomes in this population. We aimed to test the superiority of intravenous tenecteplase over non-thrombolytic standard of care in patients with minor ischaemic stroke and intracranial occlusion or focal perfusion abnormality. METHODS: In this multicentre, prospective, parallel group, open label with blinded outcome assessment, randomised controlled trial, adult patients (aged ≥18 years) were included at 48 hospitals in Australia, Austria, Brazil, Canada, Finland, Ireland, New Zealand, Singapore, Spain, and the UK. Eligible patients with minor acute ischaemic stroke (National Institutes of Health Stroke Scale score 0-5) and intracranial occlusion or focal perfusion abnormality were enrolled within 12 h from stroke onset. Participants were randomly assigned (1:1), using a minimal sufficient balance algorithm to intravenous tenecteplase (0·25 mg/kg) or non-thrombolytic standard of care (control). Primary outcome was a return to baseline functioning on pre-morbid modified Rankin Scale score in the intention-to-treat (ITT) population (all patients randomly assigned to a treatment group and who did not withdraw consent to participate) assessed at 90 days. Safety outcomes were reported in the ITT population and included symptomatic intracranial haemorrhage and death. This trial is registered with ClinicalTrials.gov, NCT02398656, and is closed to accrual. FINDINGS: The trial was stopped early for futility. Between April 27, 2015, and Jan 19, 2024, 886 patients were enrolled; 369 (42%) were female and 517 (58%) were male. 454 (51%) were assigned to control and 432 (49%) to intravenous tenecteplase. The primary outcome occurred in 338 (75%) of 452 patients in the control group and 309 (72%) of 432 in the tenecteplase group (risk ratio [RR] 0·96, 95% CI 0·88-1·04, p=0·29). More patients died in the tenecteplase group (20 deaths [5%]) than in the control group (five deaths [1%]; adjusted hazard ratio 3·8; 95% CI 1·4-10·2, p=0·0085). There were eight (2%) symptomatic intracranial haemorrhages in the tenecteplase group versus two (<1%) in the control group (RR 4·2; 95% CI 0·9-19·7, p=0·059). INTERPRETATION: There was no benefit and possible harm from treatment with intravenous tenecteplase. Patients with minor stroke and intracranial occlusion should not be routinely treated with intravenous thrombolysis. FUNDING: Heart and Stroke Foundation of Canada, Canadian Institutes of Health Research, and the British Heart Foundation.

RESUMEN

OBJECTIVE: The aim of this study was to test the effectiveness of a tailored quitline tobacco treatment ('Quitlink') among people receiving support for mental health conditions. METHODS: We employed a prospective, cluster-randomised, open, blinded endpoint design to compare a control condition to our 'Quitlink' intervention. Both conditions received a brief intervention delivered by a peer researcher. Control participants received no further intervention. Quitlink participants were referred to a tailored 8-week quitline intervention delivered by dedicated Quitline counsellors plus combination nicotine replacement therapy. The primary outcome was self-reported 6 months continuous abstinence from end of treatment (8 months from baseline). Secondary outcomes included additional smoking outcomes, mental health symptoms, substance use and quality of life. A within-trial economic evaluation was conducted. RESULTS: In total, 110 participants were recruited over 26 months and 91 had confirmed outcomes at 8 months post baseline. There was a difference in self-reported prolonged abstinence at 8-month follow-up between Quitlink (16%, n = 6) and control (2%, n = 1) conditions, which was not statistically significant (OR = 8.33 [0.52, 132.09] p = 0.131 available case). There was a significant difference in favour of the Quitlink condition on 7-day point prevalence at 2 months (OR = 8.06 [1.27, 51.00] p = 0.027 available case). Quitlink costs AU$9231 per additional quit achieved. CONCLUSION: The Quitlink intervention did not result in significantly higher rates of prolonged abstinence at 8 months post baseline. However, engagement rates and satisfaction with the 'Quitlink' intervention were high. While underpowered, the Quitlink intervention shows promise. A powered trial to determine its effectiveness for improving long-term cessation is warranted.

RESUMEN

ABSTRACTExecutive dysfunction is common in individuals with substance use disorder (SUD) and presents a barrier to treatment engagement. The study aimed to investigate the effectiveness of cognitive remediation (CR) for improving executive functioning and treatment retention in patients with SUD, using a stepped-wedge cluster randomized controlled trial. The sample included 527 adults enrolled across ten residential SUD treatment providers in NSW, Australia. The intervention consisted of 12 hours of CR delivered over six weeks in a group format. The comparator was treatment-as-usual (TAU). Primary outcomes included self-reported executive functioning and proportion of treatment completed (PoTC), measured as the number of days in treatment divided by the planned treatment duration. Intention-to-treat analysis did not find significant differences for self-reported executive functioning (mean difference = -2.49, 95%CI [-5.07, 0.09], p = .059) or PoTC (adjusted mean ratio = 1.09, 95%CI [0.88, 1.36], p = .442). Due to high dropout from the intention-to-treat sample (56%) a post-hoc analysis was conducted using a per-protocol approach, in which CR was associated with improved self-reported executive functioning (mean difference = -3.33, 95%CI [-6.10, -0.57], p = .019) and improved likelihood of treatment graduation (adjusted odds ratio = 2.43, 95%CI [1.43, 4.11], p < .001). More research is required to develop a CR approach that results in service-wide treatment effectiveness.

RESUMEN

BACKGROUND: Anti-inflammatory therapies reduce recurrent vascular events in coronary disease. Existing studies have reported highly conflicting findings for the association of blood inflammatory markers with vascular recurrence after stroke leading to uncertainty about the potential of anti-inflammatory therapies after stroke and no consensus about the utility of measurement of inflammatory markers in current guidelines. METHODS: We investigated the association between hsCRP (high-sensitivity C-reactive protein), IL-6 (interluekin-6), and recurrent major adverse cardiovascular events (MACE), and stroke from individual participant data from 8420 patients with ischemic stroke/transient ischemic attack from 10 prospective studies. We did within-study multivariable regression analyses and then combined adjusted risk ratio (RR) by random-effects meta-analysis. RESULTS: During 18 920 person-years of follow-up, 1407 (16.7% [95% CI, 15.9-17.5]) patients had MACE and 1191 (14.1% [95% CI, 13.4-14.9]) patients had recurrent stroke. On bivariate analysis, baseline IL-6 was associated with MACE (RR, 1.26 [95% CI, 1.10-1.43]) and recurrent stroke (RR, 1.18 [95% CI, 1.05-1.32]), per unit increase logeIL-6. Similar associations were observed for hsCRP (MACE RR, 1.19 [95% CI, 1.09-1.29]; recurrent stroke RR, 1.12 [95% CI, 1.04-1.21], per unit increase logehsCRP). After adjustment for vascular risk factors and treatment, independent associations remained with MACE (IL-6, RR, 1.12 [95% CI, 1.04-1.21]; hsCRP, RR, 1.09 [95% CI, 1.04-1.15]) and recurrent stroke (IL-6, RR, 1.09 [95% CI, 1.00-1.19]; hsCRP, RR, 1.05 [95% CI, 1.00-1.11]). Comparing the top with the bottom quarters (Q4 versus Q1), IL-6 (RR, 1.35 [95% CI, 1.09-1.67]) and hsCRP (RR, 1.31 [95% CI, 1.07-1.61]) were associated with MACE after adjustment. Similar results were observed for recurrent stroke for IL-6 (RR, 1.33 [95% CI, 1.08-1.65]) but not hsCRP (RR, 1.16 [95% CI, 0.93-1.43]). CONCLUSIONS: Blood markers of inflammation were independently associated with vascular recurrence after stroke, strengthening the rationale for randomized trials of anti-inflammatory therapies for secondary prevention after ischemic stroke/TIA.

RESUMEN

OBJECTIVE: Abstinence has been the primary treatment goal for alcohol and other drug (AOD) users attending withdrawal treatment. However, other outcomes including harm reduction have also been identified. This observational study aimed to describe participants' goals and reasons for seeking inpatient withdrawal treatment and compare the needs of clients with comorbid mental health problems and those without. METHODS: Participants completed questionnaires at intake and discharge. Questionnaires assessed reasons for entering withdrawal treatment, goals, comorbidity, and perceived help received. RESULTS: The sample comprised 1746 participants (69.4% male). Participants endorsed diverse reasons for entering withdrawal treatment. The most and least endorsed reasons were "stop using" (97.9%) and "legal reasons" (43.1%). Comorbidity groups varied significantly in their endorsement of reasons for mental health, physical health, harm reduction, financial, and legal. CONCLUSION: AOD users enter withdrawal treatment with a variety of reasons and goals including harm reduction. Variations in rates of endorsement highlight the importance of identifying individual needs dependent on mental health comorbidity.

RESUMEN

Objective: Client centered care (CCC) is strongly advocated for improving the quality of health care. The aim of the current study was to explore client and staff perspectives of a new model of CCC implemented in a residential alcohol and other drug (AOD) treatment service. Specifically, the study aimed to (i) describe the defining features of CCC, and (ii) describe the benefits and challenges of implementing CCC at the service. Methods: Participants were 18 clients and eight staff who took part in focus groups and interviews. Thematic analysis of four client focus groups and eight staff individual interviews was conducted. Results: Staff identified the defining features of CCC as flexible, comprehensive, open-minded, and inclusive. Clients and staff shared predominantly positive views on the CCC model. Shared themes included the challenge of balancing flexibility and structure, and delivering comprehensive and individualized care within the limits of staff knowledge, skills, and resources. Conclusions: Results suggest that implementing CCC across an AOD treatment setting has clear benefits to staff and clients, along with challenges that require careful consideration and planning. Future research should evaluate the effectiveness of providing guidelines that address many of the challenges associated with implementing CCC.

RESUMEN

Reducing blood pressure (BP) is a highly effective strategy for long-term stroke prevention. Despite overwhelmingly clear evidence from randomized trials that antihypertensive therapy substantially reduces the risk of stroke in primary prevention, uncertainty still surrounds the issue of BP lowering after cerebrovascular events, and the risk of recurrent stroke, coronary events, and vascular death remains significant. Important questions in a secondary prevention setting include should everyone be treated regardless of their poststroke BP, how soon after a stroke should BP-lowering treatment be commenced, how intensively should BP be lowered, what drugs are best, and how should long-term BP control be optimized and monitored. We review the evidence on BP control after a transient ischemic attack or stroke to address these unanswered questions and draw attention to some recent developments that hold promise to improve management of BP in current practice.

RESUMEN

INTRODUCTION: The 5-year recurrence risk after ischaemic stroke and transient ischaemic attack (TIA) is 25-30%. Although inflammation may be a target for prevention trials, the contribution of plaque inflammation to acute cerebrovascular events remains unclear. We investigated the association of acute inflammatory cytokines and high-sensitivity C-reactive protein (CRP) with recently symptomatic carotid atherosclerosis in a prospective cohort study. METHODS: Blood and Imaging markers of TIA BIO-TIA) is a multicentre prospective study of imaging and inflammatory markers in patients with TIA. Exclusion criteria were infection and other co-morbid illnesses associated with inflammation. CRP and serum cytokines (interleukin [IL]-6, IL-1ß, IL-8, IL-10, IL-12, interferon-γ [IFN-γ] and tumour necrosis factor-α [TNF-α]) were measured. All patients had carotid imaging. RESULTS: Two hundred and thirty-eight TIA cases and 64 controls (TIA mimics) were included. Forty-nine (20.6%) cases had symptomatic internal carotid artery stenosis. Pro-inflammatory cytokine levels increased in a dose-dependent manner across controls, TIA without carotid stenosis (CS), and TIA with CS (IL-1ß, ptrend = 0.03; IL-6, ptrend < 0.0001; IL-8, ptrend = 0.01; interferon (IFN)-γ, ptrend = 0.005; TNF-α, ptrend = 0.003). Results were unchanged when DWI-positive cases were excluded. On multivariable linear regression, only age (p = 0.01) and CS (p = 0.04) independently predicted log-IL-6. On multivariable Cox regression, CRP was the only independent predictor of 90-day stroke recurrence (adjusted hazard ratio per 1-unit increase 1.03 [95% CI: 1.01-1.05], p = 0.003). CONCLUSION: Symptomatic carotid atherosclerosis was associated with elevated cytokines in TIA patients after controlling for other sources of inflammation. High-sensitivity CRP was associated with recurrent ischaemic stroke at 90 days. These findings implicate acute plaque inflammation in the pathogenesis of cerebral thromboembolism and support a rationale for randomized trials of anti-inflammatory therapy for stroke patients, who were excluded from coronary trials.

RESUMEN

New therapeutic approaches are required for secondary prevention of residual vascular risk after stroke. Diverse sources of evidence support a causal role for inflammation in the pathogenesis of stroke. Randomized controlled trials of anti-inflammatory agents have reported benefit for secondary prevention in patients with coronary disease. We review the data from observational studies supporting a role for inflammation in pathogenesis of stroke, overview randomized controlled trials of anti-inflammatory therapy in cardiac disease and discuss the potential implications for stroke prevention therapy.

RESUMEN

BACKGROUND: After a transient ischemic attack (TIA) or minor stroke, the long-term risk of stroke and other vascular events is not well known. In this follow-up to a report on 1-year outcomes from a registry of TIA clinics in 21 countries that enrolled 4789 patients with a TIA or minor ischemic stroke from 2009 through 2011, we examined the 5-year risk of stroke and vascular events. METHODS: We evaluated patients who had had a TIA or minor stroke within 7 days before enrollment in the registry. Among 61 sites that participated in the 1-year outcome study, we selected 42 sites that had follow-up data on more than 50% of their enrolled patients at 5 years. The primary outcome was a composite of stroke, acute coronary syndrome, or death from cardiovascular causes (whichever occurred first), with an emphasis on events that occurred in the second through fifth years. In calculating the cumulative incidence of the primary outcome and secondary outcomes (except death from any cause), we treated death as a competing risk. RESULTS: A total of 3847 patients were included in the 5-year follow-up study; the median percentage of patients with 5-year follow-up data per center was 92.3% (interquartile range, 83.4 to 97.8). The composite primary outcome occurred in 469 patients (estimated cumulative rate, 12.9%; 95% confidence interval [CI], 11.8 to 14.1), with 235 events (50.1%) occurring in the second through fifth years. At 5 years, strokes had occurred in 345 patients (estimated cumulative rate, 9.5%; 95% CI, 8.5 to 10.5), with 149 of these patients (43.2%) having had a stroke during the second through fifth years. Rates of death from any cause, death from cardiovascular causes, intracranial hemorrhage, and major bleeding were 10.6%, 2.7%, 1.1%, and 1.5%, respectively, at 5 years. In multivariable analyses, ipsilateral large-artery atherosclerosis, cardioembolism, and a baseline ABCD2 score for the risk of stroke (range, 0 to 7, with higher scores indicating greater risk) of 4 or more were each associated with an increased risk of subsequent stroke. CONCLUSIONS: In a follow-up to a 1-year study involving patients who had a TIA or minor stroke, the rate of cardiovascular events including stroke in a selected cohort was 6.4% in the first year and 6.4% in the second through fifth years.

RESUMEN

BACKGROUND: Mutual support groups are an important source of long-term help for people impacted by addictive behaviors. Routine outcome monitoring (ROM) and feedback are yet to be implemented in these settings. SMART Recovery mutual support groups focus on self-empowerment and use evidence-based techniques (eg, motivational and behavioral strategies). Trained facilitators lead all SMART Recovery groups, providing an opportunity to implement ROM. OBJECTIVE: The aim of this stage 1 pilot study is to explore the feasibility, acceptability, and preliminary outcomes of a novel, purpose-built mobile health ROM and feedback app (SMART Track) in mutual support groups coordinated by SMART Recovery Australia (SRAU) over 8 weeks. METHODS: SMART Track was developed during phase 1 of this study using participatory design methods and an iterative development process. During phase 2, 72 SRAU group participants were recruited to a nonrandomized, prospective, single-arm trial of the SMART Track app. Four modes of data collection were used: ROM data directly entered by participants into the app; app data analytics captured by Amplitude Analytics (number of visits, number of unique users, visit duration, time of visit, and user retention); baseline, 2-, and 8-week follow-up assessments conducted through telephone; and qualitative telephone interviews with a convenience sample of study participants (20/72, 28%) and facilitators (n=8). RESULTS: Of the 72 study participants, 68 (94%) created a SMART Track account, 64 (88%) used SMART Track at least once, and 42 (58%) used the app for more than 5 weeks. During week 1, 83% (60/72) of participants entered ROM data for one or more outcomes, decreasing to 31% (22/72) by the end of 8 weeks. The two main screens designed to provide personal feedback data (Urges screen and Overall Progress screen) were the most frequently visited sections of the app. Qualitative feedback from participants and facilitators supported the acceptability of SMART Track and the need for improved integration into the SRAU groups. Participants reported significant reductions between the baseline and 8- week scores on the Severity of Dependence Scale (mean difference 1.93, SD 3.02; 95% CI 1.12-2.73) and the Kessler Psychological Distress Scale-10 (mean difference 3.96, SD 8.31; 95% CI 1.75-6.17), but no change on the Substance Use Recovery Evaluator (mean difference 0.11, SD 7.97; 95% CI -2.02 to 2.24) was reported. CONCLUSIONS: Findings support the feasibility, acceptability, and utility of SMART Track. Given that sustained engagement with mobile health apps is notoriously difficult to achieve, our findings are promising. SMART Track offers a potential solution for ROM and personal feedback, particularly for people with substance use disorders who attend mutual support groups.

RESUMEN

Background and Purpose- In randomized trials of symptomatic carotid endarterectomy, only modest benefit occurred in patients with moderate stenosis and important subgroups experienced no benefit. Carotid plaque 18F-fluorodeoxyglucose uptake on positron emission tomography, reflecting inflammation, independently predicts recurrent stroke. We investigated if a risk score combining stenosis and plaque 18F-fluorodeoxyglucose would improve the identification of early recurrent stroke. Methods- We derived the score in a prospective cohort study of recent (<30 days) non-severe (modified Rankin Scale score ≤3) stroke/transient ischemic attack. We derived the SCAIL (symptomatic carotid atheroma inflammation lumen-stenosis) score (range, 0-5) including 18F-fluorodeoxyglucose standardized uptake values (SUVmax <2 g/mL, 0 points; SUVmax 2-2.99 g/mL, 1 point; SUVmax 3-3.99 g/mL, 2 points; SUVmax ≥4 g/mL, 3 points) and stenosis (<50%, 0 points; 50%-69%, 1 point; ≥70%, 2 points). We validated the score in an independent pooled cohort of 2 studies. In the pooled cohorts, we investigated the SCAIL score to discriminate recurrent stroke after the index stroke/transient ischemic attack, after positron emission tomography-imaging, and in mild or moderate stenosis. Results- In the derivation cohort (109 patients), recurrent stroke risk increased with increasing SCAIL score (P=0.002, C statistic 0.71 [95% CI, 0.56-0.86]). The adjusted (age, sex, smoking, hypertension, diabetes mellitus, antiplatelets, and statins) hazard ratio per 1-point SCAIL increase was 2.4 (95% CI, 1.2-4.5, P=0.01). Findings were confirmed in the validation cohort (87 patients, adjusted hazard ratio, 2.9 [95% CI, 1.9-5], P<0.001; C statistic 0.77 [95% CI, 0.67-0.87]). The SCAIL score independently predicted recurrent stroke after positron emission tomography-imaging (adjusted hazard ratio, 4.52 [95% CI, 1.58-12.93], P=0.005). Compared with stenosis severity (C statistic, 0.63 [95% CI, 0.46-0.80]), prediction of post-positron emission tomography stroke recurrence was improved with the SCAIL score (C statistic, 0.82 [95% CI, 0.66-0.97], P=0.04). Findings were confirmed in mild or moderate stenosis (adjusted hazard ratio, 2.74 [95% CI, 1.39-5.39], P=0.004). Conclusions- The SCAIL score improved the identification of early recurrent stroke. Randomized trials are needed to test if a combined stenosis-inflammation strategy improves selection for carotid revascularization where benefit is currently uncertain.

RESUMEN

BACKGROUND: An increasing body of evidence suggests that inflammation plays a key role in stroke, in particular stroke of atherosclerotic origin. Anti-inflammatory medications are a widely heterogeneous group of drugs that are used to suppress the innate inflammatory pathway and thus prevent persistent or recurrent inflammation. Anti-inflammatory agents have the potential to stabilise atherosclerotic plaques by impeding the inflammatory pathway. By targeting specific cytokines, the inflammatory pathway may be interrupted at various stages. OBJECTIVES: To assess the benefits and harms of anti-inflammatory medications plus standard care versus standard care with or without placebo for prevention of vascular events (stroke, myocardial infarction (MI), non-fatal cardiac arrest, unstable angina requiring revascularisation, vascular death) and all-cause mortality in people with a prior history of ischaemic stroke or transient ischaemic attack (TIA). SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL; last searched 29 May 2019); MEDLINE (1948 to 29 May 2019); Embase (1980 to 29 May 2019); the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to 29 May 2019); and Scopus (1995 to 29 May 2019). In an effort to identify additional published, unpublished, and ongoing trials, we searched several grey literature sources (last searched 30 May 2019). We incorporated all identified studies into the results section. We applied no restrictions with respect to language, date of publication, or study setting. SELECTION CRITERIA: We considered randomised controlled trials (RCTs) and cluster-randomised controlled trials that evaluated anti-inflammatory medications for prevention of major cardiovascular events following ischaemic stroke or TIA. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed for inclusion titles and abstracts of studies identified by the search. Two review authors independently reviewed full-text articles for inclusion in this review. We planned to assess risk of bias and to apply the GRADE method. MAIN RESULTS: We identified no studies that met the inclusion criteria. AUTHORS' CONCLUSIONS: There is currently a paucity of evidence on the use of anti-inflammatory medications for prevention of major cardiovascular events following ischaemic stroke or TIA. RCTs are needed to assess whether use of anti-inflammatory medications in this setting is beneficial.

RESUMEN

Background: Patient-centered care is strongly advocated as a key for improving the quality of healthcare. Research examining the impact of patient-centered care in healthcare has concluded that there are demonstrable albeit inconsistent relationships between patient experience, quality of care, and healthcare outcomes. Knowledge of the impact of patient-centered care in the treatment of substance use disorder is limited. The aim of this review was to assess relationships between indicators of patient-centered care (satisfaction and patient-reported experience measures) and patient outcomes (substance use, psychological wellbeing, and service use) among people attending treatment for substance use disorder. Methods: A systematic electronic literature search of a range of databases was conducted with variations of the search terms 'patient-centered care', 'substance use disorders', and residential or community specialist 'treatment'. The populations, interventions and outcomes were summarized and described according to the PRISMA statement. Results: A total of 25 articles were identified, of which only five included a patient-centered indicator other than satisfaction. Indicators of patient-centered care showed a generally positive association with improved outcomes, particularly between satisfaction with treatment and substance use. Nonetheless, mixed and contradictory results were not uncommon, more so for psychological wellbeing outcomes. Conclusions: There were demonstrable relationships between patient-centered indicators and outcomes for people receiving treatment for substance use disorder. However, conclusions are limited due to underrepresentation of patient-reported experience measures. Further research in the area is needed involving comparisons of patient centered indicators with outcomes and use of patient-reported experience measures together with satisfaction.

RESUMEN

Objectives: Physical health conditions cause significant disability and mortality among people living with alcohol and other drug problems. There has been limited research on the prevalence of health problems among clinical samples of people with substance use disorders, particularly among those in residential treatment. Yet residential settings provide unique opportunity for responding to health needs. To better understand the health of people attending treatment for substance use disorders, this study conducted a file review to examine the prevalence of physical health problems as identified during routine residential care. Methods: A retrospective review of client files collected between 2013 and 2017 (N = 172) was completed at a residential treatment service in NSW, Australia. Data were extracted to examine the prevalence of physical health problems recorded at entry into treatment. Correlates of health problems were estimated using bivariate descriptive analyses and logistic regression. Results: The majority of clients in treatment for substance use had a comorbid physical health problem (80.7%). Musculoskeletal problems were the most frequently reported medical issue (38.6%). Odds for some physical health problems were related to client gender, age, and primary substance of concern. Male gender remained the strongest predictor of dental health problems when controlling for age and substance type (odds ratio [OR] = 3.60). Primary alcohol use remained the strongest predictor of nutritional deficiencies when controlling for client age (OR = 4.43). Among clients with a physical health problem and who had a treatment episode of at least 14 days (n = 110), just over half (55.5%) were referred to a health-related practitioner or service during their treatment episode. Conclusions: This study contributes to the literature by reporting on the incidence of physical health problems among people in residential treatment for substance use disorders. The high prevalence of physical health morbidity iterates the role of non-medical staff working within drug and alcohol services in the identification of client health needs. The findings support calls for systematic screening of physical health as part of routine care for substance use disorders improved integration of substance treatment and the broader primary health care system.

RESUMEN

Background and Purpose- Plaque inflammation contributes to stroke and coronary events. 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) identifies plaque inflammation-related metabolism. Almost no prospective data exist on the relationship of carotid 18F-FDG uptake and early recurrent stroke. Methods- We did a multicenter prospective cohort study BIOVASC (Biomarkers/Imaging Vulnerable Atherosclerosis in Symptomatic Carotid disease) of patients with carotid stenosis and recent stroke/transient ischemic attack with 90-day follow-up. On coregistered carotid 18F-FDG PET/computed tomography angiography, 18F-FDG uptake was expressed as maximum standardized uptake value (SUVmax) in the axial single hottest slice. We then conducted a systematic review of similar studies and pooled unpublished individual-patient data with 2 highly similar independent studies (Dublin and Barcelona). We analyzed the association of SUVmax with all recurrent nonprocedural stroke (before and after PET) and with recurrent stroke after PET only. Results- In BIOVASC (n=109, 14 recurrent strokes), after adjustment (for age, sex, stenosis severity, antiplatelets, statins, diabetes mellitus, hypertension, and smoking), the hazard ratio for recurrent stroke per 1 g/mL SUVmax was 2.2 (CI, 1.1-4.5; P=0.025). Findings were consistent in the independent Dublin (n=52, hazard ratio, 2.2; CI, 1.1-4.3) and Barcelona studies (n=35, hazard ratio, 2.8; CI, 0.98-5.5). In the pooled cohort (n=196), 37 recurrent strokes occurred (29 before and 8 after PET). Plaque SUVmax was higher in patients with all recurrence ( P<0.0001) and post-PET recurrence ( P=0.009). The fully adjusted hazard ratio of any recurrent stroke was 2.19 (CI, 1.41-3.39; P<0.001) and for post-PET recurrent stroke was 4.57 (CI, 1.5-13.96; P=0.008). Recurrent stroke risk increased across SUVmax quartiles (log-rank P=0.003). The area under receiver operating curve for all recurrence was 0.70 (CI, 0.59-0.78) and for post-PET recurrence was 0.80 (CI, 0.64-0.96). Conclusions- Plaque inflammation-related 18F-FDG uptake independently predicted future recurrent stroke post-PET. Although further studies are needed, 18F-FDG PET may improve patient selection for carotid revascularization and suggest that anti-inflammatory agents may have benefit for poststroke vascular prevention.

RESUMEN

BACKGROUND: Executive functioning impairment is common in substance use disorder and is a major risk factor for poor treatment outcomes, including treatment drop-out and relapse. Cognitive remediation interventions seek to improve executive functioning and offer a promising approach to increase the efficacy of alcohol and other drug (AOD) treatments and improve long-term therapeutic outcomes. This protocol describes a study funded by the NSW Agency for Clinical Innovation that assesses the effectiveness of delivering a six-week group-based intervention of cognitive remediation in an ecologically valid sample of people attending residential AOD treatment services. We primarily aim to investigate whether cognitive remediation will be effective in improving executive functioning and treatment retention rates. We will also evaluate if cognitive remediation may reduce long-term AOD use and rates of health service utilisation, as well as improve personal goal attainment, quality of life, and client satisfaction with treatment. In addition, the study will involve an economic analysis of the cost of delivering cognitive remediation. METHODS/DESIGN: The study uses a stepped wedge cluster randomised design, where randomisation will occur at the cluster level. Participants will be recruited from ten residential AOD treatment services provided by the non-government sector. The intervention will be delivered in 12 one-hour group-based sessions over a period of six weeks. All participants who are expected to receive treatment for the duration of the six-week intervention will be asked to participate in the study. The clusters of participants who are randomly assigned to the treatment condition will complete cognitive remediation in addition to treatment as usual (TAU). Primary and secondary outcome assessments will be conducted at pre-cognitive remediation/TAU phase, post-cognitive remediation/TAU phase, two-month follow-up, four-month follow-up, six-month follow-up, and eight-month follow-up intervals. DISCUSSION: This study will provide comprehensive data on the effect of delivering a cognitive remediation intervention within residential AOD treatment services. If shown to be effective, cognitive remediation may be incorporated as an adjunctive intervention in current treatment programs.

RESUMEN

Background: Routine outcome monitoring (ROM) is an important component of service provision and qualitity assurance procedures. However, a major logistical and financial challenge for organizations is successfully following up participants once they have left residential alcohol and other drug treatment. The aim of the current study was to assess the impact and effectiveness of an "early" follow-up contact and brief interview on subsequent 3-month ROM follow-up success. Methods: Participants were 800 clients attending specialist residential alcohol and other drug treatment provided by The Salvation Army. As part of routine outcome assessment procedures, all people attending these programs are asked to complete a 3-month follow-up assessment. Participants were randomly allocated either to the early contact condition (i.e., "early" 2-week follow-up contact prior to the 3-month follow-up assessment) or to the control condition (i.e., no "early" 2-week follow-up prior to the 3-month follow-up assessment). The primary outcomes were the proportion of participants who were followed up and surveyed at 3 months. Results: There were significantly higher follow-up rates at 3 months post discharge for participants in the early contact group (55.6%) compared with the control condition (46.1%). Although there were higher rates of 3-month follow-up for participants in the early contact group, rates of successful survey completion were not significantly different between the 2 groups. Conclusions: Including an early 2-week telephone call prior to the 3-month assessment increased the number of participants we were able to follow up at 3 months post discharge but did not improve the rate of survey participation at 3 months. The additional costs associated with this activity and the modest increase in follow-up rates need to be considered prior to organizations investing in these follow-up enhancement activities.

RESUMEN

Objective: Comorbid eating disorders (EDs) and ED symptoms are highly prevalent among women with substance use disorders and may be a barrier to recovery. Higher rates of psychiatric illness are common when more than one disorder is present. Yet little is known about the rates and risk factors for EDs/ED symptoms in women attending treatment centers in Australia. The primary aim is to examine the prevalence of ED symptoms among women attending treatment centers. This study also examines past physical and sexual abuse and mental health as specific predictors of EDs/ED symptoms. Methods: Participants were 1,444 women attending residential treatment for substance use issues provided by the Salvation Army in Australia. Measures included the Addiction Severity Index, the Eating Disorder Screen for Primary Care, medication use, hospitalization, mental health, and past abuse. Results: Alcohol was the primary substance of concern for 53.3% of the women, followed by amphetamines (17.5%), and the mean age was 37.83 years (SD = 10.8). Nearly 60% of women screened positive for ED symptoms and 32% reported a previous or current ED. Women with a history of sexual abuse had significantly greater odds (1.96) of positive screening for an ED compared to those without a history of sexual abuse. Similarly, compared to women without a history of physical abuse, those who did have a history had significantly higher odds (1.59) of a positive screen for an ED. These women were also significantly more likely to have had a health care provider recommend they take medications for psychological or emotional problems in the past 30 days, χ2(1) = 8.42, p = .004, and during their lifetime, χ2(1) = 17.89, p < .001. They also had a significantly greater number of overnight hospitalizations for medical problems compared to those who screened negative, t(137) = -2.19, p = .03. Conclusions: Women with comorbid substance use issues and EDs are highly likely to have a history of past abuse. This combination of comorbidities makes treatment and recovery difficult. Increased awareness and research are required to explore integrated approaches to treatment that accommodate these vulnerabilities and improve long-term outcomes.

RESUMEN

Objective: It is common for people attending alcohol and other substance dependence treatment to present with multiple unhealthy lifestyle behaviors such as high rates of smoking, physical inactivity, and poor diet. Healthy lifestyle interventions are increasing in importance in the general population, but have been underexamined within alcohol and other substance use populations. The purpose of the current study was to pilot "Healthy Recovery," a group program that primarily aimed to help people attending alcohol or other substance dependence treatment to reduce or quit smoking. The program also encourages participants to increase physical activity and to eat more servings of fruit and vegetables. Methods: The current study was conducted as a non-randomized controlled pilot trial. All participants were attending residential substance dependence treatment provided by the Australian Salvation Army. In addition to treatment as usual, participants in the treatment condition completed Healthy Recovery (n = 50) and participants in the control group completed an online depression program (n = 27). The study examined the health outcomes of participants (i.e., smoking, physical activity, fruit and vegetable intake, and symptom distress) and the feasibility of running the group sessions within the residential facilities. Results: Within-treatment effects demonstrated medium to large positive effects for reductions in smoking and increases in physical activity, servings of fruit, and servings of vegetables for people completing Healthy Recovery. When compared to the control condition, there were medium effects in favor of the Healthy Recovery condition for reductions in smoking and increases in physical activity. There was a small effect for servings of fruit and no effect for servings of vegetables. Conclusions: Results from this study demonstrated that people attending residential substance dependence treatment are willing and capable of engaging in multiple health behavior change interventions.
