Predischarge Injectable Versus Oral Naltrexone to Improve Postdischarge Treatment Engagement Among Hospitalized Veterans with Alcohol Use Disorder: A Randomized Pilot Proof-of-Concept Study.

ABSTRACT: Injectable naltrexone for alcohol use disorders (AUDs) has been efficacious in several studies. It has not been (i) compared head-to-head with oral naltrexone or (ii) examined in the hospital setting as an intervention that might facilitate treatment attendance after hospital discharge.Fifty-four hospitalized veterans identified as having DSM-IV-TR alcohol dependence were randomized to receive (i) a 50 mg oral naltrexone plus a 30-day prescription or (ii) a 380 mg intramuscular naltrexone injection prior to discharge. Of 113 veteran inpatients deemed eligible based on screening criteria, 54 met final eligibility criteria and were enrolled and randomized. Baseline data included demographics, alcohol consumption, and comorbidity. Measures of treatment initiation and engagement and alcohol consumption were reassessed at 14- and 45-day follow-ups.Thirty-five participants (64.8%) completed the entire study protocol (received a study medication and completed 14- and 45-day follow-ups). Among those who received a study medication (n = 45), 77.8% completed all follow-up interviews. This pilot study was not designed to have sufficient statistical power for hypothesis testing, and thus, as expected, there were no significant differences between groups in medication adherence (self-report of >80% of daily doses taken in oral group; receipt of second injection in the injection group), treatment engagement (at least treatment 3 visits in the 30 days postdischarge, and 2 or more visits per month in each of the 3 months following discharge) or alcohol consumption at 14 or at 45 days (p > 0.05). The median number of drinks among the entire cohort in the 2 weeks prior to hospitalization (128 drinks) was significantly higher than at day 14 (0 drinks, p < 0.001) or day 45 (0 drinks, p < 0.001). Rates of medication adherence were 62% in the oral group and 61% in the injection group.Results indicate feasibility for larger, more definitive study. Both groups had significant reductions in alcohol consumption over time and high-treatment engagement rates. Both oral and injectable formulations are feasible to initiate prior to discharge for hospital inpatients identified as having an AUD.

Project description:ObjectivesPrevention programs that can help adults improve the quality of their diets to reduce cancer risk are needed. This Phase IIa study prospectively tested a mHealth intervention designed to improve adherence to dietary quality guidelines for cancer prevention.MethodsAll participants (N = 62) received nutrition education and a self-regulation skills curriculum, with a primary target of changing grocery shopping behavior. Using a randomized, factorial design, the study varied whether each of the following 4 components were added to the 20-week intervention: (1) location-triggered app messaging, delivered when individuals arrived at grocery stores, (2) reflections on benefits of change, delivered with extra coaching time and tailored app messages, (3) coach monitoring, in which food purchases were digitally monitored by a coach, and (4) involvement of a household member in the intervention.ResultsBenchmarks were successfully met for recruitment, retention, and treatment acceptability. Across conditions, there were significant reductions in highly processed food intake (P < .001, η2 = .48), red and processed meat intake (P < .001, η2 = .20), and sugar-sweetened beverage intake (P = .008, η2 = .13) from pre-to post-treatment. Analyses examining whether each intervention component influenced change across time found that participants who received coach monitoring increased their intake of fruits, vegetables, and fiber, whereas those with no coach monitoring had less improvement (P = .01, η2 = .14). The improvement in red and processed meat was stronger among participants with household support ON, at a marginally significant level, than those with household support OFF (P = .056, η2 = .07).ConclusionThis study showed feasibility, acceptability, and preliminary signals of efficacy of a remotely delivered intervention to facilitate adherence to dietary guidelines for cancer prevention and that coach monitoring and household support may be especially effective strategies. A fully powered clinical trial is warranted to test an optimized version of the intervention that includes nutrition education, self-regulation skills training, coach monitoring, and household member involvement.Trial registrationClinicalTrials.gov NCT04947150.

Project description:IntroductionTight glycemic control (TGC) has shown benefits but has been difficult to achieve consistently. STAR (Stochastic TARgeted) is a flexible, model-based TGC approach directly accounting for intra- and inter- patient variability with a stochastically derived maximum 5% risk of blood glucose (BG) < 4.0 mmol/L. This research assesses the safety, efficacy, and clinical burden of a STAR TGC controller modulating both insulin and nutrition inputs in pilot trials.MethodsSeven patients covering 660 hours. Insulin and nutrition interventions are given 1-3 hourly as chosen by the nurse to allow them to manage workload. Interventions are calculated by using clinically validated computer models of human metabolism and its variability in critical illness to maximize the overlap of the model-predicted (5-95th percentile) range of BG outcomes with the 4.0-6.5 mmol/L band while ensuring a maximum 5% risk of BG < 4.0 mmol/L. Carbohydrate intake (all sources) was selected to maximize intake up to 100% of SCCM/ACCP goal (25 kg/kcal/h). Maximum insulin doses and dose changes were limited for safety. Measurements were made with glucometers. Results are compared to those for the SPRINT study, which reduced mortality 25-40% for length of stay ≥3 days. Written informed consent was obtained for all patients, and approval was granted by the NZ Upper South A Regional Ethics Committee.ResultsA total of 402 measurements were taken over 660 hours (~14/day), because nurses showed a preference for 2-hourly measurements. Median [interquartile range, (IQR)] cohort BG was 5.9 mmol/L [5.2-6.8]. Overall, 63.2%, 75.9%, and 89.8% of measurements were in the 4.0-6.5, 4.0-7.0, and 4.0-8.0 mmol/L bands. There were no hypoglycemic events (BG < 2.2 mmol/L), and the minimum BG was 3.5 mmol/L with 4.5% < 4.4 mmol/L. Per patient, the median [IQR] hours of TGC was 92 h [29-113] using 53 [19-62] measurements (median, ~13/day). Median [IQR] results: BG, 5.9 mmol/L [5.8-6.3]; carbohydrate nutrition, 6.8 g/h [5.5-8.7] (~70% goal feed median); insulin, 2.5 U/h [0.1-5.1]. All patients achieved BG < 6.1 mmol/L. These results match or exceed SPRINT and clinical workload is reduced more than 20%.ConclusionsSTAR TGC modulating insulin and nutrition inputs provided very tight control with minimal variability by managing intra- and inter- patient variability. Performance and safety exceed that of SPRINT, which reduced mortality and cost in the Christchurch ICU. The use of glucometers did not appear to impact the quality of TGC. Finally, clinical workload was self-managed and reduced 20% compared with SPRINT.

Project description:BackgroundEstimation of glomerular filtration rate (GFR) using estimated glomerular filtration rate creatinine (eGFRcr) is central to clinical practice but has limitations. We tested the hypothesis that serum metabolomic profiling can identify novel markers that in combination can provide more accurate GFR estimates.MethodsWe performed a cross-sectional study of 200 African American Study of Kidney Disease and Hypertension (AASK) and 265 Multi-Ethnic Study of Atherosclerosis (MESA) participants with measured GFR (mGFR). Untargeted gas chromatography/dual mass spectrometry- and liquid chromatography/dual mass spectrometry-based quantification was followed by the development of targeted assays for 15 metabolites. On the log scale, GFR was estimated from single- and multiple-metabolite panels and compared with eGFR using the Chronic Kidney Disease Epidemiology equations with creatinine and/or cystatin C using established metrics, including the proportion of errors >30% of mGFR (1-P30), before and after bias correction.ResultsOf untargeted metabolites in the AASK and MESA, 283 of 780 (36%) and 387 of 1447 (27%), respectively, were significantly correlated (P ≤ 0.001) with mGFR. A targeted metabolite panel eGFR developed in the AASK and validated in the MESA was more accurate (1-P30 3.7 and 1.9%, respectively) than eGFRcr [11.2 and 18.5%, respectively (P < 0.001 for both)] and estimating GFR using cystatin C (eGFRcys) [10.6% (P = 0.02) and 9.1% (P < 0.05), respectively] but was not consistently better than eGFR using both creatinine and cystatin C [3.7% (P > 0.05) and 9.1% (P < 0.05), respectively]. A panel excluding creatinine and demographics still performed well [1-P30 6.4% (P = 0.11) and 3.4% (P < 0.001) in the AASK and MESA] versus eGFRcr.ConclusionsMultimetabolite panels can enable accurate GFR estimation. Metabolomic equations, preferably excluding creatinine and demographic characteristics, should be tested for robustness and generalizability as a potential confirmatory test when eGFRcr is unreliable.

Project description:OBJECTIVES:This study aimed to investigate if the use of a transition team was feasible for patients with diabetes being discharged from hospital on injectable diabetes therapies. DESIGN:Pilot, randomised controlled trial. SETTING:The trial was conducted between 2014 and 2016 conjointly by a tertiary referral hospital and a community healthcare provider. PARTICIPANTS:Hospital inpatients (n=105) on new injectable diabetes therapies were randomised 1:1 to transition team or standard care. The transition team received in-home diabetes education 24-48 hours postdischarge, with endocrinologist review 2-4 weeks and 16 weeks postdischarge. MAIN OUTCOME MEASURES:The primary outcome was feasibility, defined by percentage of patients successfully receiving the intervention. Secondary outcomes included safety, defined by hospital readmission and emergency department presentations within 16 weeks postrandomisation, and treatment satisfaction, measured using Diabetes Treatment Satisfaction Questionnaire (DTSQ). Exploratory outcomes included length of stay (LOS) and change in haemoglobin A1c (HbA1c) throughout the study. RESULTS:The intervention was deemed feasible (85% (95% CI 73% to 94%)). No difference in safety between groups was detected. No difference in change in HbA1c between groups was detected (standard care median HbA1c -1.5% (IQR -3.7% to -0.2%) vs transition team median HbA1c -1.9% (IQR -3.8% to -0.2%), p=0.83). There was a trend towards reduced LOS in the transition team group (per protocol, standard care median LOS 8 (IQR 5.5-12); transition team median LOS 6 (IQR 3-12), p=0.06). There was a significant improvement in patient satisfaction in the transition team (standard care median 10.5 (IQR 8.5-16); transition team DTSQ change version median 15 (IQR 10-17.5), p=0.047), although interpretability is limited by missing data. CONCLUSION:This study demonstrated that the use of a novel transition diabetes team is a feasible alternative model of care.

Project description:Background: Transcranial direct current stimulation (tDCS) has been used extensively in patient populations to facilitate motor network plasticity. However, it has not been studied in patients with brain tumors. We aimed to determine the feasibility of a preoperative motor training and tDCS intervention in patients with glioma. In an exploratory manner, we assessed changes in motor network connectivity following this intervention and related these changes to predicted electrical field strength from the stimulated motor cortex. Methods: Patients with left-sided glioma (n=8) were recruited in an open label proof of concept pilot trial and participated in four consecutive days of motor training combined with tDCS. The motor training consisted of a 60-min period where the subject learned to play the piano with their right hand. Concurrently, they received 40 min of 2 mA anodal tDCS of the left motor cortex. Patients underwent task and resting state fMRI before and after this intervention. Changes in both the connectivity of primary motor cortex (M1) and general connectivity across the brain were assessed. Patient specific finite element models were created and the predicted electrical field (EF) resulting from stimulation was computed. The magnitude of the EF was extracted from left M1 and correlated to the observed changes in functional connectivity. Results: There were no adverse events and all subjects successfully completed the study protocol. Left M1 increased both local and global connectivity. Voxel-wide measures, not constrained by a specific region, revealed increased global connectivity of the frontal pole and decreased global connectivity of the supplementary motor area. The magnitude of EF applied to the left M1 correlated with changes in global connectivity of the right M1. Conclusion: In this proof of concept pilot study, we demonstrate for the first time that tDCS appears to be feasible in glioma patients. In our exploratory analysis, we show preoperative motor training combined with tDCS may alter sensorimotor network connectivity. Patient specific modeling of EF in the presence of tumor may contribute to understanding the dose-response relationship of this intervention. Overall, this suggests the possibility of modulating neural networks in glioma patients.
