Real-World Dalbavancin Use for Serious Gram-Positive Infections: Comparing Outcomes Between People Who Use and Do Not Use Drugs.

Background: Dalbavancin has been used off-label to treat invasive bacterial infections in vulnerable populations like people who use drugs (PWUD) because of its broad gram-positive coverage and unique pharmacological properties. This retrospective, multisite study examined clinical outcomes at 90 days in PWUD versus non-PWUD after secondary treatment with dalbavancin for bacteremia, endocarditis, osteomyelitis, septic arthritis, and epidural abscesses. Methods: Patients at 3 teaching hospitals who received dalbavancin for an invasive infection between March 2016 and May 2022 were included. Characteristics of PWUD and non-PWUD, infection highlights, hospital stay and treatment, and outcomes were compared using χ2 for categorical variables, t test for continuous variables, and nonparametric tests where appropriate. Results: There were a total of 176 patients; 78 were PWUD and 98 were non-PWUD. PWUD were more likely to have a patient-directed discharge (26.9% vs 3.1%; P < .001) and be lost to follow-up (20.5% vs 7.14%; P < .01). Assuming loss to follow-up did not achieve clinical cure, 73.1% of PWUD and 74.5% of non-PWUD achieved clinical cure at 90 days (P = .08). Conclusions: Dalbavancin was an effective treatment option for invasive gram-positive infections in our patient population. Despite higher rates of patient-directed discharge and loss to follow-up, PWUD had similar rates of clinical cure at 90 days compared to non-PWUD.

Developing a remotely delivered intensive outpatient program adapted for hospitalized patients with opioid use disorder: A qualitative study.

Introduction: Individuals with opioid use disorder (OUD) who inject drugs have an elevated risk of experiencing serious injection-related infections. While such infections can be treated, treatment for the underlying OUD is often limited. One potential strategy for more intensive addiction treatment is to offer a remotely delivered intensive outpatient program (IOP), adapted from an existing remote IOP ("Smart IOP"). We aimed to conduct a qualitative study to gather feedback on Smart IOP and identify adaptations needed for hospitalized patients. Methods: Individuals with OUD and a history of serious injection-related infections completed a semi-structured interview and were shown samples of the videos and program content. The interviews were transcribed verbatim and coded to conduct a thematic analysis. Results: Seventeen individuals participated. The mean age was 40.8 years and 70.6 % were men. Participants reported that IOP during the hospitalization would have been helpful to their recovery. The themes that emerged were the importance of medications for OUD, having a relapse prevention plan, engaging with a recovery coach, and ensuring treatment linkage post-discharge. Other themes included the recognition of the severity of one's illness and the emotional experiences related to the hospitalization. Conclusions: Participants expressed the value of an IOP during hospitalization and provided insights into the support needed while hospitalized. The tailored IOP is now being developed and will undergo a pilot feasibility trial.

Digitally Assisted Peer Recovery Coach to Facilitate Linkage to Outpatient Treatment Following Inpatient Alcohol Withdrawal Treatment: Proof-of-Concept Pilot Study.

BACKGROUND: Alcohol use disorder (AUD), associated with significant morbidity and mortality, continues to be a major public health problem. The COVID-19 pandemic exacerbated the impact of AUD, with a 25% increase in alcohol-related mortality from 2019 to 2020. Thus, innovative treatments for AUD are urgently needed. While inpatient alcohol withdrawal management (detoxification) is often an entry point for recovery, most do not successfully link to ongoing treatment. Transitions between inpatient and outpatient treatment pose many challenges to successful treatment continuation. Peer recovery coaches-individuals with the lived experience of recovery who obtain training to be coaches-are increasingly used to assist individuals with AUD and may provide a degree of continuity during this transition. OBJECTIVE: We aimed to evaluate the feasibility of using an existing care coordination app (Lifeguard) to assist peer recovery coaches in supporting patients after discharge and facilitating linkage to care. METHODS: This study was conducted on an American Society of Addiction Medicine-Level IV inpatient withdrawal management unit within an academic medical center in Boston, MA. After providing informed consent, participants were contacted by the coach through the app, and after discharge, received daily prompts to complete a modified version of the brief addiction monitor (BAM). The BAM inquired about alcohol use, risky, and protective factors. The coach sent daily motivational texts and appointment reminders and checked in if BAM responses were concerning. Postdischarge follow-up continued for 30 days. The following feasibility outcomes were evaluated: (1) proportion of participants engaging with the coach before discharge, (2) proportion of participants and the number of days engaging with the coach after discharge, (3) proportion of participants and the number of days responding to BAM prompts, and (4) proportion of participants successfully linking with addiction treatment by 30-day follow-up. RESULTS: All 10 participants were men, averaged 50.5 years old, and were mostly White (n=6), non-Hispanic (n=9), and single (n=8). Overall, 8 participants successfully engaged with the coach prior to discharge. Following discharge, 6 participants continued to engage with the coach, doing so on an average of 5.3 days (SD 7.3, range 0-20 days); 5 participants responded to the BAM prompts during the follow-up, doing so on an average of 4.6 days (SD 6.9, range 0-21 days). Half (n=5) successfully linked with ongoing addiction treatment during the follow-up. The participants who engaged with the coach post discharge, compared to those who did not, were significantly more likely to link with treatment (83% vs 0%, χ2=6.67, P=.01). CONCLUSIONS: The results demonstrated that a digitally assisted peer recovery coach may be feasible in facilitating linkage to care following discharge from inpatient withdrawal management treatment. Further research is warranted to evaluate the potential role for peer recovery coaches in improving postdischarge outcomes.

Impact of cannabidiol on reward- and stress-related neurocognitive processes among individuals with opioid use disorder: A pilot, double-blind, placebo-controlled, randomized cross-over trial.

Introduction: Opioid use disorder (OUD) continues to be a significant public health concern. Medications for OUD (MOUD) such as buprenorphine reduce overdose mortality, but relapses occur often, leading to adverse outcomes. Preliminary data suggest that cannabidiol (CBD) may be a potential adjunctive treatment to MOUD by attenuating cue-reactivity. This pilot study sought to evaluate the impact of a single dose of CBD on reward- and stress-related neurocognitive processes implicated in relapse among those with OUD. Methods: The study was a pilot, double-blind, placebo-controlled, randomized cross-over trial aimed at assessing the effects of a single dose of CBD (Epidiolex®) 600 mg or matching placebo administered to participants with OUD receiving either buprenorphine or methadone. Vital signs, mood states, pain, opioid withdrawal, cue-induced craving, attentional bias, decision-making, delayed discount, distress tolerance, and stress-reactivity were examined at each testing session on two separate testing days at least 1 week apart. Results: Ten participants completed all study procedures. Receipt of CBD was associated with a significant decrease in cue-induced craving (0.2 vs. 1.3, p = 0.040), as well as reduced attentional bias toward drug-related cues as measured by the visual probe task (-80.4 vs. 100.3, p = 0.041). No differences were found among all the other outcomes examined. Discussion: CBD may have promise as an adjunct to MOUD treatment by attenuating the brain response to drug-related cues, which, in turn, may reduce the risk of relapse and overdoses. Further research is warranted to evaluate the potential for CBD as an adjunctive therapy for individuals in treatment for OUD.

Delicious and difficult to resist?: Inhibitory control differs in young women after exposure to food and non-food commercials.

Unhealthy food marketing, a ubiquitous food stimulus, may impact response inhibition, making it more difficult to maintain healthy eating behaviors. Individuals with disordered eating may be particularly susceptible to altered inhibition responses to food stimuli, making them more vulnerable to unhealthy food marketing, which could perpetuate their disordered eating behaviors. The present study examined response inhibition following exposure to food commercials in young women who reported either high levels of disordered eating (HEC) or low/no disordered eating (LEC) (N = 27; age: M = 19.28, SD = 1.01) by measuring event related potentials (ERPs) during a stop-signal task embedded with food stimuli. Results indicated that participants had significantly higher accuracy on stop trials displaying unhealthy food stimuli than trials displaying healthy food stimuli after viewing non-food commercials but displayed no difference after viewing food commercials. LEC individuals displayed a smaller N200/P300 amplitude in response to food stimuli on the stop-signal task after watching food commercials as compared to non-food commercials, but this difference did not exist for HEC individuals. Results indicate that unhealthy food commercials may impact behavioral and electrophysiological correlates of response inhibition evoked by food stimuli in young women, and individuals with disordered eating might actually be less responsive to food marketing than those without disordered eating.

Resting-state EEG, Substance use and Abstinence After Chronic use: A Systematic Review.

Resting-state EEG reflects intrinsic brain activity and its alteration represents changes in cognition that are related to neuropathology. Thereby, it provides a way of revealing the neurocognitive mechanisms underpinning chronic substance use. In addition, it is documented that some neurocognitive functions can recover following sustained abstinence. We present a systematic review to synthesize how chronic substance use is associated with resting-state EEG alterations and whether these spontaneously recover from abstinence. A literature search in Medline, PsycINFO, Embase, CINAHL, Web of Science, and Scopus resulted in 4088 articles, of which 57 were included for evaluation. It covered the substance of alcohol (18), tobacco (14), cannabis (8), cocaine (6), opioids (4), methamphetamine (4), and ecstasy (4). EEG analysis methods included spectral power, functional connectivity, and network analyses. It was found that long-term substance use with or without substance use disorder diagnosis was associated with broad intrinsic neural activity alterations, which were usually expressed as neural hyperactivation and decreased neural communication between brain regions. Some studies found the use of alcohol, tobacco, cocaine, cannabis, and methamphetamine was positively correlated with these changes. These alterations can partly recover from abstinence, which differed between drugs and may reflect their neurotoxic degree. Moderating factors that may explain results inconsistency are discussed. In sum, resting-state EEG may act as a potential biomarker of neurotoxic effects of chronic substance use. Recovery effects awaits replication in larger samples with prolonged abstinence. Balanced sex ratio, enlarged sample size, advanced EEG analysis methods, and transparent reporting are recommended for future studies.
