Managing Multiple Chronic Conditions during COVID-19 Among Patients with Social Health Risks.

BACKGROUND: Optimal care for persons with multiple chronic conditions (MCC) requires primary and specialty care continuity, access to multiple providers, social risk assessment, and self-management support. The COVID-19 pandemic abruptly changed primary care delivery to increase reliance on telehealth and virtual care. We report on the experiences of individuals with MCC and their family caregivers on managing their health and receiving health care during the initial pandemic. METHODS: Semistructured qualitative interviews with 30 patients (19 English speaking, 11 Spanish speaking) plus 9 accompanying care partners, who had 2+ primary care encounters between March 1, 2020, and November 30, 2020, 2+ chronic conditions, and 1 or more self-reported social risks. Questions focused on access to and experiences with care, roles for care partners, and self-management during the first 6 months of the pandemic. RESULTS: Participants experienced substantial changes in care delivery. The most commonly reported changes were a shift to more virtual relative to in-person care and shifting roles for care partners. Changes fostered new perspectives on self-management and an appreciation of personal resilience and self-reliance. Virtual care was an acceptable complement to in-person care, though not a substitute for periodic in-person visits. It was more acceptable for English speakers and with a usual provider. CONCLUSION: New models of care delivery that recognize patient and family resilience and resourcefulness, emphasize provider continuity, and combine virtual and in-person care may support self-management for individuals with MCC and social needs.

Asbestos exposures associated with the use and handling of drilling mud additives.

This paper summarizes historical asbestos exposure data collected during the handling of short-fiber chrysotile asbestos that was used as an additive to drilling fluid in oil and gas exploration. A total of 1171 industrial hygiene (IH) personal and area air samples were collected and analyzed from more than 20 drilling rigs between 1972 and 1985. The dataset consists of 1097 short-term samples (<240 min) with more than 80% having sample durations less than 30 min. Average airborne fiber concentrations measured during asbestos handling activities ranged from 0.62 f/cc to 3.39 f/cc using phase-contrast microscopy (PCM). An additional 14 samples were considered long-term samples (>240 min) and there were 60 samples with no reported sample duration. Eight-hour time-weighted average (8-h TWA) results, calculated using short-term samples, along with long-term samples greater than 240 min, did not exceed contemporaneous Occupational Safety and Health Administration (OSHA) permissible exposure limits (PELs). This analysis fills a data gap in the evaluation of asbestos exposures from the use of drilling mud additives (DMAs) that contained chrysotile asbestos.

COVID-19-Related Financial Hardship Is Associated With Depression and Anxiety in Substance Use Treatment Across Gender and Racial Groups.

ABSTRACT: Many individuals lost their employment during the COVID-19 pandemic and experienced financial hardship. These experiences may increase risk for co-occurring conditions, including substance use disorders (SUDs) and related symptoms of depression and anxiety. This study aimed to examine the associations between COVID-19-related financial hardship and/or job loss and co-occurring symptoms, across gender and racial groups. Respondents (N = 3493) included individuals entering SUD treatment in the United States in March-October of 2020. Results demonstrated that COVID-19-related financial hardship and unemployment in the household was associated with greater depression and anxiety severity among people in SUD treatment (p's < 0.05). Our findings highlight financial hardship and loss of employment as risk factors for co-occurring depression and anxiety. However, additive effects between marginalized identity status and COVID-19 economic hardship on co-occurring symptoms were not observed.

Obese patients with CEAP (clinical, etiology, anatomy, pathophysiology) C2 and C3 disease show enhanced symptom improvement after endovenous thermal ablation.

OBJECTIVE: Endovenous thermal ablation (EVTA) is a prevalent treatment option for patients with severe venous disease. However, the decision to intervene for patients with less severe disease (CEAP [clinical, etiology, anatomy, pathophysiology] C2 and C3) is less clear and becomes further complicated for patients with obesity, a pathology known to increase venous disease symptom severity. Therefore, the objective of this study was to use the Society for Vascular Surgery Vascular Quality Initiative database to evaluate outcomes after EVTA in obese patients with CEAP C2 and C3 venous insufficiency. METHODS: Using the Society for Vascular Surgery Vascular Quality Initiative database, we retrospectively analyzed the initial procedure of all patients with a CEAP clinical class of C2 or C3 who underwent EVTA from January 2015 to December 2021. Patients were grouped by obesity, defined as a body mass index of ≥30 kg/m2. The primary outcome was the change in venous clinical severity score (VCSS) from the procedure to the patient's initial follow-up. The secondary outcomes included the change in patient-reported outcomes at follow-up via the HASTI (heaviness, achiness, swelling, throbbing, itching) score, incidence of follow-up complications, and recanalization of treated veins. The change in the VCSS and HASTI score were analyzed using Student t tests, and complications and recanalization were assessed using the Fisher exact test. Significant outcomes were confirmed by multiple variable logistic regression. The remaining significant variables were then analyzed, with obesity categorized using the World Health Organization classification system to analyze how increasing obesity levels affect outcomes. RESULTS: There were 8146 limbs that met the inclusion criteria, of which 5183 (63.6%) were classified as nonobese and 2963 (36.4%) as obese. Obesity showed no impact on improvement in the VCSS (-3.29 vs -3.35; P = .408). Obesity was found to be associated with a larger improvement in overall symptoms, as evidence by a greater improvement in the HASTI score (-7.24 vs -6.62; P < .001). Obese limbs showed a higher incidence of superficial phlebitis (1.5% vs 0.7%; P = .001), but no difference was found in recanalization or any other complication. CONCLUSIONS: These data suggest that obese patients with CEAP clinical class C2 or C3 experience greater improvement in their perceived symptoms after EVTA with little difference in clinical improvement and complications compared with nonobese patients. Although obesity has been associated with increased severity of venous disease symptoms, obese patients are able to derive significant relief after treatment during the short term and may experience greater relief of symptoms than nonobese patients when treated at more mild disease presentations.

Strategies to reduce rates of severe endothermal heat-induced thrombosis following radiofrequency ablation.

OBJECTIVE: Endothermal heat-induced thrombosis (EHIT) is a potential complication of radiofrequency ablation (RFA). Data on effective prophylaxis of EHIT are limited. In 2018, a high-volume, single institution implemented strategies to decrease the incidence of EHIT, including a single periprocedural prophylactic dose of low-molecular-weight heparin to patients with a great saphenous vein (GSV) diameter of ≥8 mm or saphenofemoral junction (SFJ) diameter of ≥10 mm and limiting treatment to one vein per procedure. The size threshold was derived from existing literature. The study objective was to evaluate the effects of these institutional changes on thrombotic complication rates after RFA. METHODS: A retrospective cohort control study was conducted using the Vascular Quality Initiative database. Data were collected for patients who underwent RFA with a GSV diameter of ≥8 mm or SFJ diameter of ≥10 mm from January 2015 to July 2022. The clinical end points were thrombotic complications (ie, thrombophlebitis, EHIT, deep vein thrombosis) and bleeding complications. Patient demographic and procedural variables were included in the analysis, and significant variables after univariable logistic regression were included in a multivariable logistic regression. RESULTS: After the policy change, the overall vein center EHIT rate decreased from 2.6% to 1.5%, with a trend toward significance (P = .096). The inclusion criterion of a GSV diameter of ≥8 mm or an SFJ diameter of ≥10 mm yielded 845 patients, of whom 298 were treated before the policy change and 547 after. There was a significant reduction in the rate of EHIT classified as class ≥III (2.34 vs 0.366; P = .020) after the institutional changes. Treatment of two or more veins and an increased vein diameter were associated with an increased risk of EHIT (P = .049 and P < .001, respectively). No significant association was found between periprocedural anticoagulation and all-cause thrombotic complications or EHIT (P = .563 and P = .885, respectively). CONCLUSIONS: The institutional policy changes have led to lower rates of EHIT, with a reduction in severe EHIT rates in patients with an ≥8-mm diameter GSV or a ≥10-mm diameter SFJ treated with RFA. Of the changes implemented, restricting treatment to one vein was associated with a reduction in severe EHIT. No association was found with periprocedural low-molecular-weight heparin, although a type 2 error might have occurred. Alternative strategies to prevent thrombotic complications should be explored, such as increasing the dosage and duration of periprocedural anticoagulation, antiplatelet use, and nonpharmacologic strategies.

Intersectional Risk and the Significant Gap in Care for Persons with Co-occurring Chronic Pain and Opioid Withdrawal.

OBJECTIVES: Persons with chronic pain and women tend to enter treatment for opioid use disorder with greater opioid withdrawal severity than persons without chronic pain and men, respectively. This study examined characteristics of facilities with opioid withdrawal treatment, including gender-based services, as a function of whether they reported having a tailored pain management program. METHODS: The National Survey of Substance Abuse Treatment Services 2020 was used to examine 3942 facilities with opioid withdrawal treatment in the United States. Using a multivariable binary logistic regression model, facilities were examined for the presence of a tailored program for individuals with co-occurring pain. Regional location of the facility, ownership status, and availability of tailored gender programs, nonhospital residential services, and outpatient services served as independent variables in the analysis. RESULTS: A slight majority of the sample had a program for both adult men and adult women (n = 2010, 51.0%). Most facilities had outpatient services (n = 3289, 83.4%) and did not have a tailored program for addressing co-occurring pain (n = 2756, 69.9%). Binary logistic regression analysis showed that among opioid withdrawal facilities, programs with nonhospital residential services, government or private nonprofit funding, or tailored gender programming had higher odds of reporting having a tailored program for pain and substance use disorder. Facilities in the Western United States were most likely to have tailored programs for pain and substance use disorder. CONCLUSIONS: Future research should investigate what support patients may receive and how to better scale access to pain management during opioid withdrawal treatment.

Lung imaging patterns in connective tissue disease-associated interstitial lung disease impact prognosis and immunosuppression response.

OBJECTIVES: Interstitial lung disease (ILD) in connective tissue diseases (CTD) have highly variable morphology. We aimed to identify imaging features and their impact on ILD progression, mortality and immunosuppression response. METHODS: Patients with CTD-ILD had high-resolution chest computed tomography (HRCT) reviewed by expert radiologists blinded to clinical data for overall imaging pattern (usual interstitial pneumonia [UIP]; non-specific interstitial pneumonia [NSIP]; organizing pneumonia [OP]; fibrotic hypersensitivity pneumonitis [fHP]; and other). Transplant-free survival and change in percent-predicted forced vital capacity (FVC) were compared using Cox and linear mixed effects models adjusted for age, sex, smoking, and baseline FVC. FVC decline after immunosuppression was compared with pre-treatment. RESULTS: Of 645 CTD-ILD patients, the frequent CTDs were systemic sclerosis (n = 215), rheumatoid arthritis (n = 127), and inflammatory myopathies (n = 100). NSIP was the most common pattern (54%), followed by UIP (20%), fHP (9%), and OP (5%). Compared with UIP, FVC decline was slower for NSIP (1.1%/year, 95%CI 0.2, 1.9) and OP (3.5%/year, 95%CI 2.0, 4.9), and mortality was lower for NSIP (HR 0.65, 95%CI 0.45, 0.93) and OP (HR 0.18, 95%CI 0.05, 0.57), but higher in fHP (HR 1.58, 95%CI 1.01, 2.40). The extent of fibrosis also predicted FVC decline and mortality. After immunosuppression, FVC decline was slower compared with pre-treatment in NSIP (by 2.1%/year, 95%CI 1.4, 2.8), with no change for UIP or fHP. CONCLUSION: Multiple radiologic patterns are possible in CTD-ILD, including a fHP pattern. NSIP and OP were associated with better outcomes and response to immunosuppression, while fHP had worse survival compared with UIP.

The association of pain impact and sleep disruption with opioid withdrawal during opioid-use disorder treatment.

AIMS: Persons with opioid-use disorder (OUD) often experience opioid withdrawal and opioid craving, which can drive continued opioid use and treatment discontinuation. In addition, hyperalgesia is common among persons with OUD, yet few studies have examined the role of pain impact during OUD treatment. The purpose of the present study was to test whether opioid withdrawal and craving were elevated in the context of greater pain impact (i.e. greater pain intensity and interference), and whether these associations changed throughout treatment. METHODS: Participants in residential OUD treatment (n = 24) wore wrist actigraphy to measure sleep and completed daily measures of pain impact, opioid withdrawal and opioid craving for up to 28 days. Mixed effects models were used to examine whether daily elevations in pain impact and sleep continuity were associated with withdrawal severity and opioid craving. RESULTS: Elevations in withdrawal, but not craving, occurred on days when individuals reported higher scores on the pain impact scale. Associations between pain impact and withdrawal were present throughout treatment, but stronger during early treatment. In contrast, both withdrawal and opioid craving were elevated following nights of greater wake after sleep onset and awakenings, but these findings were often more pronounced in early treatment. CONCLUSIONS: Pain impact and sleep disturbance are 2 factors associated with opioid withdrawal and opioid craving. Novel pharmacotherapies and scalable adjunctive interventions targeting sleep and pain impact should be tested in future work to improve OUD treatment outcomes.

Knowledge, Preference, and Adverse Effects of Xylazine Among Adults in Substance Use Treatment.

This cross-sectional study evaluates aspects of xylazine adulteration of opioids among individuals entering substance use disorder treatment.

Suvorexant alters dynamics of the sleep-electroencephalography-power spectrum and depressive-symptom trajectories during inpatient opioid withdrawal.

STUDY OBJECTIVES: Opioid withdrawal is an aversive experience that often exacerbates depressive symptoms and poor sleep. The aims of the present study were to examine the effects of suvorexant on oscillatory sleep-electroencephalography (EEG) band power during medically managed opioid withdrawal, and to examine their association with withdrawal severity and depressive symptoms. METHODS: Participants with opioid use disorder (N = 38: age-range:21-63, 87% male, 45% white) underwent an 11-day buprenorphine taper, in which they were randomly assigned to suvorexant (20 mg [n = 14] or 40 mg [n = 12]), or placebo [n = 12], while ambulatory sleep-EEG data was collected. Linear mixed-effect models were used to explore: (1) main and interactive effects of drug group, and time on sleep-EEG band power, and (2) associations between sleep-EEG band power change, depressive symptoms, and withdrawal severity. RESULTS: Oscillatory spectral power tended to be greater in the suvorexant groups. Over the course of the study, decreases in delta power were observed in all study groups (ß = -189.082, d = -0.522, p = <0.005), increases in beta power (20 mg: ß = 2.579, d = 0.413, p = 0.009 | 40 mg ß = 5.265, d = 0.847, p < 0.001) alpha power (20 mg: ß = 158.304, d = 0.397, p = 0.009 | 40 mg: ß = 250.212, d = 0.601, p = 0.001) and sigma power (20 mg: ß = 48.97, d = 0.410, p < 0.001 | 40 mg: ß = 71.54, d = 0.568, p < 0.001) were observed in the two suvorexant groups. During the four-night taper, decreases in delta power were associated with decreases in depressive symptoms (20 mg: ß = 190.90, d = 0.308, p = 0.99 | 40 mg: ß = 433.33, d = 0.889 p = <0.001), and withdrawal severity (20 mg: ß = 215.55, d = 0.034, p = 0.006 | 40 mg: ß = 192.64, d = -0.854, p = <0.001), in both suvorexant groups and increases in sigma power were associated with decreases in withdrawal severity (20 mg: ß = -357.84, d = -0.659, p = 0.004 | 40 mg: ß = -906.35, d = -1.053, p = <0.001). Post-taper decreases in delta (20 mg: ß = 740.58, d = 0.964 p = <0.001 | 40 mg: ß = 662.23, d = 0.882, p = <0.001) and sigma power (20 mg only: ß = 335.54, d = 0.560, p = 0.023) were associated with reduced depressive symptoms in the placebo group. CONCLUSIONS: Results highlight a complex and nuanced relationship between sleep-EEG power and symptoms of depression and withdrawal. Changes in delta power may represent a mechanism influencing depressive symptoms and withdrawal.

A brief measure of non-drug reinforcement: Association with treatment outcomes during initial substance use recovery.

BACKGROUND: Translational research demonstrates that drug use is inversely associated with availability and engagement with meaningful non-drug reinforcers. Evaluation of non-drug reinforcement in treatment-receiving clinical populations is limited, likely owing to the time intensive nature of existing measures. This study explores the association of non-drug reinforcers with treatment outcomes using a novel, brief measure of past month non-drug reinforcement quantifying three elements: relative frequency, access, and enjoyability. METHODS: Respondents enrolled in substance use treatment (residential, intensive outpatient, and medically managed withdrawal) in clinics across the United States (N = 5481) completed standardized assessments of non-drug reinforcement and treatment outcomes (i.e., return to use and life satisfaction) one-month after treatment discharge. Non-drug reinforcement measures (availability, engagement, enjoyability) were used as predictors of return to use and life satisfaction using generalized linear models. RESULTS: Non-drug reinforcement indices were associated with return to use and life satisfaction in unadjusted models (e.g., 12.4 % versus 58.3 % return to use for those with the highest and lowest availability, respectively). Consistent results were observed in models adjusted for sociodemographic variables and risk factors (i.e., sleep disturbance, anhedonia, stress). Comparisons by drug class generally showed lower non-drug reinforcement among patients reporting heroin or methamphetamine as their primary drug. CONCLUSIONS: Results highlight the importance of non-drug reinforcement during the first month following treatment. Rapid measurement of non-drug reinforcement in stepped care settings may illuminate critical deficits in early stages of behavior change, identify those at greatest risk for return to use, and provide targets for treatment to improve recovery trajectories.

Phenylalanine requirements using the direct amino acid oxidation technique, and the effects of dietary phenylalanine on food intake, gastric emptying, and macronutrient metabolism in adult cats.

Despite Phe being an indispensable amino acid for cats, the minimum Phe requirement for adult cats has not been empirically defined. The objective of study 1 was to determine the minimum Phe requirement, where Tyr is in excess, in adult cats using the direct amino acid oxidation (DAAO) technique. Four adult male cats were used in an 8 × 4 Latin rectangle design. Cats were adapted to a basal diet for 7 d, top dressed with Phe to meet 140% of the adequate intake (NRC, 2006. Nutrient requirements of dogs and cats. Washington, DC: Natl. Acad. Press). Cats were randomly assigned to one of eight experimental Phe diets (0.29%, 0.34%, 0.39%, 0.44%, 0.54%, 0.64%, 0.74%, and 0.84% Phe in the diet on a dry matter [DM] basis). Following 1 d of diet adaptation, individual DAAO studies were performed. During each DAAO study, cats were placed into individual indirect calorimetry chambers, and 75% of the cat's daily meal was divided into 13 equal meals supplied with a dose of L-[1-13C]-Phe. Oxidation of L-[1-13C]-Phe (F13CO2) during isotopic steady state was determined from the enrichment of 13CO2 in breath. Competing models were applied using the NLMIXED procedure in SAS to determine the effects of dietary Phe on 13CO2. The mean population minimum requirement for Phe was estimated at 0.32% DM and the upper 95% population confidence limit at 0.59% DM on an energy density of 4,200 kcal of metabolizable energy/kg DM calculated using the modified Atwater factors. In study 2, the effects of a bolus dose of Phe (44 mg kg-1 BW) on food intake, gastric emptying (GE), and macronutrient metabolism were assessed in a crossover design with 12 male cats. For food intake, cats were given Phe 15 min before 120% of their daily food was offered and food intake was measured. Treatment, day, and their interaction were evaluated using PROC GLIMMIX in SAS. Treatment did not affect any food intake parameters (P > 0.05). For GE and macronutrient metabolism, cats were placed into individual indirect calorimetry chambers, received the same bolus dose of Phe, and 15 min later received 13C-octanoic acid (5 mg kg-1 BW) on 50% of their daily food intake. Breath samples were collected to measure 13CO2. The effect of treatment was evaluated using PROC GLIMMIX in SAS. Treatment did not affect total GE (P > 0.05), but cats receiving Phe tended to delay time to peak enrichment (0.05 < P ≤ 0.10). Overall, Phe at a bolus dose of 44 mg kg-1 BW had no effect on food intake, GE, or macronutrient metabolism. Together, these results suggest that the bolus dose of Phe used may not be sufficient to elicit a GE response, but a study with a greater number of cats and greater food intake is warranted.

Two studies were conducted to evaluate 1) the minimum requirement for dietary Phe and 2) the effects of Phe on gastric emptying (GE) and food intake in adult cats. In study 1, the minimum Phe requirement was estimated using the direct amino acid oxidation (DAAO) technique. Four cats were used and received all diets in random order in a Latin rectangle design (0.29%, 0.34%, 0.39%, 0.44%, 0.54%, 0.64%, 0.74%, and 0.84% Phe in the diet on a dry matter [DM] basis). The minimum Phe requirement, in the presence of excess of Tyr, for adult cats was estimated to be 0.59% DM on an energy density of 4,200 kcal of metabolizable energy/kg DM calculated using the modified Atwater factors; higher than current recommendations set in place by the National Research Council and the American Association of Feed Control Officials. In study 2, we first validated the use of the 13C-octanoic acid breath test (13C-OABT) in cats. Then, the effects of an oral bolus of Phe on food intake, GE, and macronutrient metabolism were evaluated. Phe supplementation did not influence food intake, macronutrient metabolism, or total GE, but tended to delay the time to peak GE.

Sleep Disruption Moderates the Daily Dynamics of Affect and Pain in Sickle Cell Disease.

Persons with sickle cell disease (SCD) often experience pain that can interfere with quality of life and daily activities. Pain can modulated by affect and sleep continuity; however, few studies have explored how these factors complementarily influence pain in adults with SCD. The study aims were to investigate 1) whether pain levels were heightened on days characterized by low positive affect and high negative affect, and 2) whether the relationship between affect and pain was intensified following nights of disrupted sleep. Adults with SCD (N = 25) completed ecological momentary assessments and daily sleep diaries. Mixed models were used to analyze the main and interactive effects of daily affect (positive affect and negative affect) and sleep disruption (wake after sleep onset and frequency of awakenings) on both daily average pain and daily maximum pain. Results suggested that daily average pain and maximum pain tended to be higher on days of low positive affect and high negative affect. Furthermore, the frequency of nocturnal awakenings moderated the relationship between positive affect and pain. On days where there were higher frequencies of nocturnal awakenings, low positive affect was associated with both average and maximum pain; however, this association was not observed with lower frequencies of nocturnal awakenings. The association between negative affect and maximum pain was also stronger at higher levels of awakenings. Results highlight the relevance of adjunctive interventions that target affect among populations with SCD and further suggest that sleep continuity may further facilitate these interventions, highlighting the importance of multimodal treatments. PERSPECTIVE: This study examined the effects of affect and sleep on pain among adults with sickle cell disease (SCD). Higher pain occurred on days of low positive affect and high negative affect, particularly following nights of more frequent awakenings. These findings emphasize the importance of addressing affect and sleep in SCD treatment.

Age moderates the association of optimism on craving during substance use disorder treatment.

BACKGROUND: Optimism, characterized by a positive expectancy toward future outcomes, has garnered attention for its potential role in influencing well-being and may be a protective factor in substance use disorder (SUD) treatment. This study evaluated the relationship of optimism and craving among those in substance use disorder SUD treatment. METHODS: Drawing from a cohort of 4201 individuals in residential SUD treatment programs, this study used both cross-sectional and longitudinal assessment to examine tonic (steady-state) and cue-induced (phasic) cravings across individuals primarily using eight classes of substances. Previous research established that optimism increases during adulthood and peaks during an individual's 50s. This study sought to establish if the association between optimism and craving is moderated by age during the first week of treatment and if that relationship changes over the course of treatment both within and between-person. RESULTS: This study found a negative correlation between optimism and craving intensity. Elevated optimism scores correlated with substantially reduced levels of both tonic (ß = -0.31, p < 0.001) and cue-induced (ß = -0.29, p < 0.001) cravings. Age was a significant moderator of the relationship between optimism and craving such that as individuals age, the potency of optimism in mitigating cravings gradually attenuates (interaction for tonic craving: ß = 0.06, p < 0.001; interaction for cue-induced craving: ß = 0.05, p < 0.001). Reflected in the fact that in older individuals' cravings tended to converge toward lower or moderate levels, regardless of their optimism scores. CONCLUSIONS: By delineating the contemporaneous association between high optimism and lower cravings, the study suggests that interventions aimed at fostering optimism may represent an avenue to improve the effectiveness of SUD treatment, especially in emerging adults.

Naloxone Knowledge and Attitudes Towards Overdose Response Among Family Members of People who Misuse Opioids.

Providing family members of individuals with opioid use disorders (OUD) naloxone is a cost-effective way to prevent overdose deaths. However, misconceptions and negative attitudes towards naloxone hinder family engagement with naloxone programs. This study examines factors associated with knowledge and attitudes toward naloxone among adults with close family members who misused opioids. Adults with family members (parent, step-parent, child, spouse, sibling, or step-sibling) who misused opioids (N = 299) completed a web-based survey. Participants were recruited through treatment providers, community groups, and social media. Surveys assessed naloxone knowledge, attitudes toward overdose response, demographics, completion of naloxone training, attitude toward medications for OUD, and family members' overdose history. Multiple regression was used to identify factors associated with naloxone knowledge (Model 1) and attitudes toward overdose response (Model 2). A graduate degree (B = .35, p < .003) and a history of overdose (B = 0.21, p = .032) were associated with greater naloxone knowledge. Age (B = .11, p < .001), race/ethnicity (B = -1.39, p = .037), naloxone training (B = 2.70, p < .001), and more positive attitude toward medications for OUD (B = 1.50, p = .003) were associated with attitudes toward overdose response. Family members are potential allies in reducing drug overdose deaths, and families may need broader education about naloxone. Awareness of previous overdose was associated with greater naloxone knowledge. Findings related to race/ethnicity suggest the need to reach family members of minoritized racial groups to provide access to naloxone training. Findings point to where education and distribution efforts may focus on increasing knowledge and improving attitudes among those closest to people with OUD.

Increases in primary opioid use disorder diagnoses co-occurring with anxiety or depressive disorder diagnoses in mental health treatment in the United States, 2015-2019.

BACKGROUND: Opioid use disorders (OUDs) often co-occur with anxiety and depressive disorders. While the proportion of mental health (MH) treatment facilities providing substance use treatment has increased, the proportion of these facilities able to simultaneously treat MH and substance use decreased. This warrants investigation into the integrated treatment needs of persons with a primary OUD diagnosis treated in MH treatment facilities. METHODS: Using the Mental Health Client Level Data, we examined a sample of N = 83,975 adults with OUD as their primary diagnosis who received treatment from a MH treatment facility in the United States from 2015 to 2019. Joinpoint regression was used to examine annual trends of the number of individuals with co-occurring anxiety or depression diagnoses. RESULTS: Most of the sample were men (53.7%) and received treatment in a community-based program (93.3%). Approximately 17% of the sample had either an anxiety or depressive disorder diagnosis. Approximately 9% of our sample had an anxiety disorder diagnosis, and 10% had a depressive disorder diagnosis. An increase in the number of individuals with a co-occurring anxiety disorder diagnosis from 2015 to 2019 was identified (annual percent change (APC) = 61.4; 95% confidence interval (CI) = [10.0, 136.9]; p =.029). An increase in the number of individuals with a co-occurring depressive disorder diagnosis from 2015 to 2019 was identified (APC = 39.0; 95% CI = [7.4; 79.9]; p =.027). CONCLUSIONS: This study highlights increases in adults receiving MH treatment for OUD having co-occurring anxiety or depression diagnoses, furthering the importance of integrated dual disorder treatment.

Risk factors for inpatient facility admission among home health care patients with diabetes.

BACKGROUND: Home health care (HHC) patients with diabetes are at high risk for inpatient admissions. PURPOSE: To identify variables associated with inpatient admissions among adults age ≥50 with diabetes receiving HHC in the community and in assisted living (AL). METHODS: Retrospective HHC data (collected October 2021 to March 2022 in the Southern United States) from the Outcome and Assessment Information Set D were analyzed with logistic regression (n = 5,308 patients). DISCUSSION: The inpatient admission rate was 29.5%. For community-dwelling patients, multiple hospitalizations, depression, limited cognitive function, decreased activities of daily living (ADL) performance, and unhealed pressure ulcer or injury ≥stage 2 were significantly associated with inpatient admission. For those in AL, multiple prior hospitalizations and decreased ability to perform ADLs were associated with inpatient admission. CONCLUSION: Understanding risk factors for inpatient admissions among patients with diabetes can support the identification of at-risk patients and inform interventions.

Direct Observation of Enhanced Electron-Phonon Coupling in Copper Nanoparticles in the Warm-Dense Matter Regime.

Warm dense matter (WDM) represents a highly excited state that lies at the intersection of solids, plasmas, and liquids and that cannot be described by equilibrium theories. The transient nature of this state when created in a laboratory, as well as the difficulties in probing the strongly coupled interactions between the electrons and the ions, make it challenging to develop a complete understanding of matter in this regime. In this work, by exciting isolated ∼8 nm copper nanoparticles with a femtosecond laser below the ablation threshold, we create uniformly excited WDM. Using photoelectron spectroscopy, we measure the instantaneous electron temperature and extract the electron-ion coupling of the nanoparticle as it undergoes a solid-to-WDM phase transition. By comparing with state-of-the-art theories, we confirm that the superheated nanoparticles lie at the boundary between hot solids and plasmas, with associated strong electron-ion coupling. This is evidenced both by a fast energy loss of electrons to ions, and a strong modulation of the electron temperature induced by strong acoustic breathing modes that change the nanoparticle volume. This work demonstrates a new route for experimental exploration of the exotic properties of WDM.

Binge Drinking and Cannabis Use among Transgender and Gender-Diverse Young Adults in Michigan.

Substance use rates are higher among transgender and gender-diverse people than cisgender people. Rates of substance use are also higher among young adults compared with other age groups. However, little research examines substance use among transgender and gender-diverse young adults. This study examines factors associated with binge drinking and cannabis use among transgender and gender-diverse young adults in Michigan. Participants (N = 78; ages 18-25) completed an online survey that included demographics and substance use and related characteristics. Race, stimulant misuse, and sedative misuse were associated with more frequent binge drinking. Older age and past-year pain reliever misuse were associated with less frequent cannabis use. Past-year stimulant use and using cannabis alone were associated with more frequent cannabis use. These findings suggest that additional marginalized identities may increase the risk for maladaptive substance use. Future research should examine substance use behaviors and correlates to inform interventions among this population.
