RESUMEN
Background: During the COVID-19 pandemic, there was an increase in the number of unhoused individuals in Asheville, North Carolina resulting in more tent encampments.Understanding the physical, mental, and socially determined health characteristics associated with being unhoused can help guide stakeholders with policy development, healthcare program planning, and funding decisions to support unhoused individuals. Methods: In this study, we used an observational cross-section methodology. Using a convenience sample approach, we interviewed 101 participants who were receiving services from 2 emergency hotel shelters, a day center, and a resource center. Data were analyzed using descriptive statistics, and open-ended responses were collected and grouped to provide context. Results: Most participants were White (71%) and identified as male (76%). Over 60% reported having a high school education or advanced degree. Of the participants, 76% reported being unhoused for more than 6 months, and their last permanent housing was in Western North Carolina. Dental disease, chronic pain, and hypertension were common physical conditions. PTSD, depression, and anxiety were common mental health conditions. A lack of transportation was the most noted socially determined challenge. Marijuana, methamphetamine, and alcohol were the most often used substances, where methamphetamine was noted to be particularly problematic for the participants. Conclusion: Understanding the physical, mental, and social issues of the complex unhoused population can assist policymakers, healthcare providers, and other stakeholders in addressing challenges and testing improvement strategies.
RESUMEN
Transitions from high-dose methadone to buprenorphine for treatment of opioid use disorder (OUD) present risk of precipitated withdrawal related to the introduction of a high-affinity partial agonist at the mu-opioid receptor after occupancy by a lower-affinity full agonist. Various strategies have been explored to maintain patient stability during this process, including microdosing buprenorphine. Current literature lacks consensus on an optimal setting and strategy for initiating a buprenorphine microdosing protocol and gives little detail on patients' conditions after the acute transition period. We report a 6-day microdosing transition from methadone 100 mg directly to sublingual buprenorphine, followed by a 20-day period of monitoring and additional treatment. This patient tolerated a sublingual buprenorphine microdosing protocol while using supportive medications with a peak Clinical Opiate Withdrawal Scale score of 6. The patient's most significant withdrawal symptoms occurred several days after completion of the microdosing process. This case demonstrates the feasibility of using a transmucosal buprenorphine formulation in microdosing transitions from high-dose methadone directly to buprenorphine, and highlights the utility of a medically monitored intensive inpatient setting (American Society of Addiction Medicine level 3.7) in providing appropriate monitoring and treatment during and after a microdosing transition.

People who use drugs (PWUD) often experience barriers to preventative health care. During the COVID-19 pandemic, due to lapses in harm reduction services, several public health experts forecasted subsequent increases in diagnosis of HIV in PWUD. As many inpatient hospitals reworked patient flow during the COVID-19 surge, we hypothesized that HIV testing in PWUD would decrease. To answer this question, we compiled a deidentified list of hospitalized patients with electronic medical record indicators of substance use-a positive urine toxicology screen, prescribed medications to treat opioid use disorder, a positive CIWA score, or a positive CAGE score-admitted between January, 2020 and August, 2020. The outcome of interest was HIV test completion during inpatient hospitalization. The study used logistic regression to examine associations between type of substance use and receipt of HIV test. The study grouped substance use type into four groups (1) opioids (oxycodone, fentanyl, or other opiates) or opioid use disorder treatments (methadone, buprenorphine, naltrexone); (2) stimulant use (cocaine or amphetamines); (3) alcohol use (presence of a positive CAGE or CIWA score or alcohol present on toxicology screen); and (4) benzodiazepine use (benzodiazepines present on toxicology screen). The proportion of PWUD who were tested for HIV increased from 10.4% in January, 2020 to 28.2% in April, 2020 and back down to 12% in August. Notably, there was an inverse trend over time for number of people hospitalized with drug use, from 259 in January to a nadir of 85 in April, and then up to 217 in August, 2020. Contrary to our hypothesis, HIV testing increased during the COVID-19 pandemic, and we discuss explanations for this finding. The decrease in HIV testing post-pandemic peak is a reminder that we must work to develop interventions that lead to sustained high rates of HIV testing for all people, and especially for PWUD.

People with opioid use disorder (OUD) have worse hospital outcomes and higher healthcare costs. There are rising reports of people with OUD also using other classes of drugs, however patterns of substance use have not been evaluated for differential effects on hospital outcomes. We performed a data-analysis of the Healthcare Utilization Project's National Readmissions Database, examining the effects of patterns of substance use, age, gender, and diagnosis on the outcomes of Against Medical Advice (AMA) discharges and 30-day readmissions. About one-third of the patients with OUD who were admitted to the hospital had at least one additional substance use disorder (SUD). Thirteen percent of persons with OUD were discharged AMA, and 12% were readmitted to the hospital within 30 days of discharge. Compared to people with OUD alone, people who used stimulants had increased odds of AMA discharge (aOR 1.83 (CI 1.73, 1.96)) and 30-day readmission (aOR 1.30 (95% CI 1.23, 1.37)). Multiple concomitant substance use disorders were associated with increased odds of AMA discharge and 30-day readmission. Conclusions: People with OUD have high rates of both AMA discharges and 30 day-readmissions, and there is a layered effect of increasing co-occurring SUDs leading to worse hospitalization outcomes. The heterogeneity of drug use patterns needs to be considered when developing strategies to improve health care outcomes for people with substance use disorder.

The authors investigated whether patients receiving buprenorphine maintenance treatment (BMT) will have corrected QT (QTc) prolongation after taking buprenorphine for an extended period of time. They also compared QTc prolongation for patients in methadone maintenance treatment (MMT) versus BMT to determine which medication is the better option for patients with heart disease. A retrospective chart review study of 73 patients in BMT and 55 patients in MMT was performed. A linear regression model with a one-sided P value was used for data analysis. The MMT group had statistically significant prolongation of QTc compared with the BMT group (F = 3.94, P = .0001). Being diagnosed with congestive heart failure and taking methadone were the only individual variables that showed a statistically significant association with a QTc prolongation > 500 ms. The model as a whole showed statistical significance (F = 5.203, P = .007). Being diagnosed with congestive heart failure was the only individual variable that showed a statistically significant association with mortality. The model as a whole also showed statistical significance (F = 17.15, P = .000). This study supports previous findings that methadone may be associated with QTc prolongation, whereas buprenorphine may not. This study has the advantage of confirming that QTc prolongation persists in patients in MMT but not in those in BMT over an extended period of time (i.e., 5 years). Buprenorphine might a better first-line opioid maintenance treatment for patients with heart disease because buprenorphine was not associated with QTc prolongation. Patients in BMT may not need to be screened routinely for QTc prolongation.

The essential role for phosphatidylinositol-4-phosphate (PtdIns(4)P) in vesicle-mediated protein transport from the trans-Golgi network (TGN) was first described in the budding yeast Saccharomyces cerevisiae. However, the identity of downstream effectors of PtdIns(4)P in this system has been elusive. Here, we show that Drs2p, a type IV P-type ATPase required for phospholipid translocase (flippase) activity and transport vesicle budding from the TGN, is an effector of PtdIns(4)P. Drs2p-dependent flip of a fluorescent phosphatidylserine analogue across purified TGN membranes requires synthesis of PtdIns(4)P by the phosphatidylinositol-4-kinase (PI(4)K) Pik1p. PtdIns(4)P binds to a regulatory domain in the C-terminal tail of Drs2p that has homology to a split PH domain and is required for Drs2p activity. In addition, basic residues required for phosphoinositide binding overlap a previously mapped binding site for the ArfGEF Gea2p. ArfGEF binding to this C-terminal domain also stimulates flippase activity in TGN membrane preparations. These interactions suggest the presence of a coincidence detection system used to activate phospholipid translocation at sites of vesicle formation.
