Gender Differences in Civil Commitment Hearing Experience for Persons Who Use Opioids.

OBJECTIVES: Civil commitment has increasingly served as a court-based legal intervention for severe opioid use, but little research has examined the civil commitment (CC) hearing process from the perspective of the person who is committed. Despite documented gender differences in opioid use and experiences within the legal system, past research has also not investigated gender differences in perceptions of the CC process for persons who use opioids. METHODS: Participants were 121 persons (43% female) with opioid use who were interviewed upon arrival at the CC facility about their experience of the CC hearing process in Massachusetts. RESULTS: Two thirds of participants were taken to the commitment hearing by police, and 59.5% shared a cell with others while waiting. Overall, the commitment intake process at the courthouse took over 5 hours. Participants spent, on average, less than 15 minutes with their lawyer before the hearing, and a majority of CC hearings lasted less than 15 minutes. Once transferred to a CC facility, opioid withdrawal management began within 4 hours. Compared with women, men reported longer wait times between the hearing and transfer, as well as longer wait times for withdrawal management at the facility ( P < 0.05). Women perceived worse interactions with the judge and greater dissatisfaction with the commitment process compared with men ( P < 0.05). CONCLUSIONS: There were few gender differences in the experience of CC. However, overall, participants reported a lengthy court process and low levels of perceived procedural justice.

Replacement of dietary carbohydrate with protein increases fat mass and reduces hepatic triglyceride synthesis and content in female obese Zucker rats.

Previous studies have demonstrated both energy restriction (ER) and higher protein (HP), lower carbohydrate (LC) diets downregulate hepatic de novo lipogenesis. Little is known about the independent and combined impact of ER and HP/LC diets on tissue-specific lipid kinetics in leptin receptor-deficient, obese rodents. This study investigated the effects of ER and dietary macronutrient content on body composition; hepatic, subcutaneous adipose tissue (SAT), and visceral AT (VAT) lipid metabolic flux (2 H2 O-labeling); and blood and liver measures of cardiometabolic health in six-week-old female obese Zucker rats (Leprfa+/fa+ ). Animals were randomized to a 10-week feeding intervention: ad libitum (AL)-HC/LP (76% carbohydrate/15% protein), AL-HP/LC (35% protein/56% carbohydrate), ER-HC/LP, or ER-HP/LC. ER groups consumed 60% of the feed consumed by AL. AL gained more fat mass than ER (P-energy = 0.012) and HP/LC gained more fat mass than HC/LP (P-diet = 0.025). Hepatic triglyceride (TG) concentrations (P-interaction = 0.0091) and absolute hepatic TG synthesis (P-interaction = 0.012) were lower in ER-HP/LC versus ER-HC/LP. ER had increased hepatic, SAT, and VAT de novo cholesterol fractional synthesis, absolute hepatic cholesterol synthesis, and serum cholesterol (P-energy≤0.0035). A HP/LC diet, independent of energy intake, led to greater gains in fat mass. A HP/LC diet, in the context of ER, led to reductions in absolute hepatic TG synthesis and TG content. However, ER worsened cholesterol metabolism. Increased adipose tissue TG retention with the HP/LC diet may reflect improved lipid storage capacity and be beneficial in this genetic model of obesity.

Randomized Controlled Trial of Aerobic Exercise for Smoking Cessation among Individuals with Elevated Depressive Symptoms.

INTRODUCTION: Adults with depression have higher rates of cigarette smoking and are more likely to relapse than those without depression. Pharmacological, psychological, and combined interventions have largely yielded small improvements in smoking outcomes for adults with depression. Aerobic exercise (AE) may facilitate smoking cessation in this subpopulation. METHODS: This study was a 12-week two-arm randomized controlled trial that evaluated the effect of a moderate-intensity AE program compared to a health education contact (HEC) control on smoking cessation in adults with elevated depressive symptoms (mild to severe). Participants (n=231) were randomized to AE or HEC and received smoking cessation treatment (telephone counseling and nicotine replacement therapy). Primary (biologically confirmed 7-day point prevalence abstinence) and secondary (depressive symptoms, objective and self-reported physical activity, and cardiorespiratory fitness) outcomes were assessed at baseline, 3-, 6-, and 12-months. Data were analyzed with mixed-effects generalized linear models controlling for age, gender, nicotine dependence, history of major depression disorder, and month of follow-up assessment. RESULTS: There were no significant differences in primary or secondary outcomes between the AE and HEC groups. CONCLUSIONS: The AE program was not superior to HEC in facilitating smoking cessation, increases in physical activity, or improved depressive symptoms. Given evidence for the positive acute effects of exercise on mood and smoking urges, future research should consider testing alternative exercise approaches for aiding smoking cessation beyond structured, aerobic exercise programs. IMPLICATIONS: This study found that an adjunctive aerobic exercise (AE) program was not superior to a health education contact control for adults with elevated depressive symptoms, all of whom also received standard smoking cessation treatment. This finding adds to the growing body of literature that structured aerobic exercise programs for smoking cessation may have limited efficacy for cessation outcomes. Future research is needed to test alternative methods of integrating AE into smoking cessation treatment, such as strategically using exercise to manage cravings and low mood in the moment.

Strategies Used to Manage Chronic Pain in HIV-Disease: Comparing Persons Prescribed Opioids Versus Persons not Receiving Opioids.

Chronic pain is common in people living with HIV (PLWH), causes substantial disability and is associated with limitations in daily activities. Opioids are commonly prescribed for pain treatment among PLWH, but evidence of sustained efficacy is mixed. There is little information available on how PLWH who have chronic pain use multimodal strategies in pain management. The current cross-sectional study examined background characteristics, self-reported pain, and the use of other pain treatments among 187 PLWH with chronic pain and depressive symptoms who were and were not prescribed opioids. Approximately 20.9% of participants reported using prescription opioids at the time of the study interview. These individuals were significantly more likely to report having engaged in physical therapy or stretching, strengthening or aerobic exercises in the previous 3 months, recent benzodiazepine use, and receiving disability payments. There were no significant differences in pain characteristics (pain-related interference, average pain severity, and worst pain severity) between the two groups. Those not prescribed opioids were more likely to report better concurrent physical functioning and general health, and fewer physical role limitations, but higher depression symptom severity. Our findings suggest that many PLWH with chronic pain and depressive symptoms express high levels of pain with deficits in physical function or quality of life despite their use of opioids. The high rate of co-use of opioids and benzodiazepines (30.8%) is a concern because it may increase risk of overdose. An integrated care approach that includes a variety of effective non-pharmacologic treatment strategies such as physical therapy may be beneficial in reducing the reliance on opioids for pain management.

Anger and substance use in HIV-positive patients with chronic pain.

Chronic pain increases the risk of substance use in people living with HIV (PLWH). Depression and anxiety have also been identified as risk factors for substance use among PLWH. Relatedly, other negative mood states, such as anger, may influence chronic pain among PLWH. The current cross-sectional study examined whether the distinct negative mood state of anger is associated with substance use among 187 PLWH who report chronic pain. Using negative binomial regression analyses, we found higher levels of anger were positively associated with alcohol use. Higher levels of anger were inversely associated with benzodiazepine use. No association was found between anger and marijuana use, and there were no significant interactions between anger and pain severity on substance use. Our findings suggest that anger is an independent risk factor for substance use among PLWH and chronic pain. Addressing anger may be useful when adapting behavioral therapies in the treatment of pain among PLWH.

Opioid relapse and MOUD outcomes following civil commitment for opioid use.

INTRODUCTION: Opioid use disorder (OUD) continues to present a major public health problem in the United States. Civil commitment for substance use is one mandatory form of treatment for severe opioid use that has become increasingly available in recent years, but empirical data on this approach are lacking. This study examines clinical outcomes of civil commitment in a sample of adults with severe opioid use. METHODS: Participants were 121 persons with opioid use who were interviewed at the point of entry into civil commitment, then followed for 12 weeks after their release. RESULTS: Prior to civil commitment, this sample exhibited serious substance use characteristics (including high rates of illicit opioid use, other substance use, and injection drug use), as well as mental health problems (diagnoses of depression and anxiety disorders). During follow-up, approximately 41 % of the sample reported at least one illicit opioid use day. More than 64 % of the sample reported at least one day of medication for opioid use disorder (MOUD) receipt, and participants were significantly less likely to use illicit opioids on days that they received MOUDs. No participants died during the follow-up period. CONCLUSIONS: In this sample of persons with severe opioid use, clinical outcomes of civil commitment included illicit opioid relapse as well as varying levels of MOUD uptake. Civil commitment may be a viable method for short-term prevention of overdose for a subset of this vulnerable patient population.

Characteristics associated with motivation to stop substance use and improve skin and needle hygiene among hospitalized patients who inject drugs.

Background: Hospitalizations for people who inject drugs (PWID) are opportunities to address substance use. However, little is known about hospitalized PWIDs' motivation to stop substance use or improve skin and needle hygiene, common means for reducing injection sequelae. Methods: We used baseline data from a randomized controlled trial of a behavioral intervention to improve skin and needle hygiene among 252 hospitalized PWID between January 2014 and June 2018. We examined motivation (scale 1-10) to stop substance use, use new needles, and clean skin and used multiple linear regression models to evaluate characteristics associated with these outcomes. Results: PWID were recruited during injection-related (154, 61.1%) and non-injection-related hospitalizations (98, 38.9%). Motivation to stop substance use was 7.11 (SD = 2.67), use new needles was 7.8 (SD = 1.9), and clean skin was 6.7 (SD = 2.3). In adjusted models, experiencing an injection-related hospitalization was not significantly associated (p > 0.05) with motivation to stop substance use (ß = -0.76, SE = 0.299), use new needles (ß = 0.301, SE = 0.255), or clean skin (ß = 0.476, SE = 0.323). Number of past-year skin and soft tissue infections was negatively associated with motivation to use new needles (ß = -0.109, SE = 0.049, p < 0.05) and clean skin (ß = -0.131, SE = 0.062, p < 0.05). Greater opioid withdrawal was associated with lower motivation to use new needles (ß = -0.275, SE = 0.92, p < 0.01). Conclusions: Among hospitalized PWID, motivation to stop substance use and improve skin and needle hygiene was moderately high, but injection-related hospitalizations were not associated with greater motivation. Efforts to reduce injection sequelae for all hospitalized PWID are needed.

Risk behaviors among persons civilly committed for opioid use.

Despite the growth in civil commitment for persons who use opioids, we know little about the kinds of risk behaviors among those committed. This study examined the behaviors that a judge might use to determine if there is sufficient evidence that an individual's opioid use poses a risk for serious harm. The study recruited participants (n = 121) from three Massachusetts Department of Public Health civil commitment facilities in 2018. We used a list of risk behaviors that courts consider supportive of opioid-related civil commitment. Participants averaged 28 years of age, 56% were male, and 91% met criteria for severe opioid use disorder. Participants endorsed an average of 9 of the 27 risk behaviors. On average, participants endorsed three of the six drug use behaviors representing a danger to themselves, four of eleven behaviors representing an inability to care for or protect themselves (home safety, weight loss), and two of ten behaviors representing a danger to others (driving high or drunk). Participants who reported they were "not at all pleased" to have been civilly committed endorsed significantly (p = .009) fewer behaviors representing a danger to themselves than those who said they were at least "a little pleased." We conclude that the majority of individuals civilly committed for opioid use are engaging in multiple high-risk behaviors that pose a serious risk of harm to themselves.

Under the Skin: The Relationship Between Subcutaneous Injection and Skin Infections Among People Who Inject Drugs.

OBJECTIVES: People who inject drugs (PWID) are at increased risk for numerous negative health outcomes. Subcutaneous injections (aka skin popping) can result in greater risk of skin and soft tissue infections (SSTIs), but less is known about PWID who choose this route of administration. This study compares subcutaneous injectors to intravenous injectors, characterizes those who inject subcutaneously, and examines whether subcutaneous injection is associated with SSTIs in the past year. METHODS: A cohort of hospitalized PWID (n = 252) were interviewed regarding injection-related behaviors, history of SSTI, and knowledge of subcutaneous injection risk. We examined differences between those who do and do not inject subcutaneously and used a negative binomial regression model to estimate adjusted odds associating subcutaneous injection and SSTI. RESULTS: Participants averaged 38 years, with 58.3% male, 59.5% White, 20.6% Black, and 15.9% Latinx. PWID who performed subcutaneous injection were not demographically different from other PWID; however, the mean rate of past year SSTIs was higher for persons injecting subcutaneously than for those who did not (1.98 vs 0.96, P < 0.001). Persons injecting subcutaneously did not differ from those who injected intravenously in terms of their knowledge of subcutaneous injection risk (P = 0.112) and knowledge score was not associated with SSTIs (P = 0.457). CONCLUSIONS: PWID who perform subcutaneous injections are demographically similar to other PWID but had higher rates of past year SSTIs. Knowledge of subcutaneous injection risk was not associated with SSTI risk.

Acceptance of chronic pain in depressed patients with HIV: correlations with activity, functioning, and emotional distress.

Chronic pain is highly prevalent among persons with HIV (PWH), as is depression. Both comorbidities might contribute to, as well as be maintained by, avoidance-based coping. A promising alternative to avoidance-based coping is acceptance. Acceptance of pain is associated with improved functioning and quality of life in chronic pain patients, but this relationship has not been substantially explored among PWH. Cross-sectional data from 187 adult outpatients enrolled in a randomized trial for depressed PWH with chronic pain were analyzed. Controlling for pain severity and demographics, the relationships among pain acceptance and indicators of activity, functioning, and emotional distress (i.e., anxiety and anger) were assessed in seven regression models. No significant relationships were found between self-reported physical activity or objective measurement of mean steps/day with pain acceptance. Results revealed an inverse relationship between chronic pain acceptance and pain-related functional interference (by.x = -.52, p < .01) and a positive relationship with self-reported functioning (by.x = 7.80, p < .01). A significant inverse relationship with anxiety symptoms (by.x = -1.79, p < .01) and pain acceptance was also found. Acceptance of chronic pain can facilitate decreased emotional distress, improved well-being, and better functioning and quality of life. Further investigation of chronic pain acceptance among PWH could inform the development of acceptance-based interventions.

Divergent effects of sex and calcium/vitamin D supplementation on serum magnesium and markers of bone structure and function during initial military training.

Maintaining Mg status may be important for military recruits, a population that experiences high rates of stress fracture during initial military training (IMT). The objectives of this secondary analysis were to (1) compare dietary Mg intake and serum Mg in female and male recruits pre- and post-IMT, (2) determine whether serum Mg was related to parameters of bone health pre-IMT, and (3) whether Ca and vitamin D supplementation (Ca/vitamin D) during IMT modified serum Mg. Females (n 62) and males (n 51) consumed 2000 mg of Ca and 25 µg of vitamin D/d or placebo during IMT (12 weeks). Dietary Mg intakes were estimated using FFQ, serum Mg was assessed and peripheral quantitative computed tomography was performed on the tibia. Dietary Mg intakes for females and males pre-IMT were below the estimated average requirement and did not change with training. Serum Mg increased during IMT in females (0·06 ± 0·08 mmol/l) compared with males (-0·02 ± 0·10 mmol/l; P < 0·001) and in those consuming Ca/vitamin D (0·05 ± 0·09 mmol/l) compared with placebo (0·001 ± 0·11 mmol/l; P = 0·015). In females, serum Mg was associated with total bone mineral content (BMC, ß = 0·367, P = 0·004) and robustness (ß = 0·393, P = 0·006) at the distal 4 % site, stress-strain index of the polaris axis (ß = 0·334, P = 0·009) and robustness (ß = 0·420, P = 0·004) at the 14 % diaphyseal site, and BMC (ß = 0·309, P = 0·009) and stress-strain index of the polaris axis (ß = 0·314, P = 0·006) at the 66 % diaphyseal site pre-IMT. No significant relationships between serum Mg and bone measures were observed in males. Findings suggest that serum Mg may be modulated by Ca/vitamin D intake and may impact tibial bone health during training in female military recruits.

Retention in care for persons with opioid use disorder transitioning from sublingual to injectable buprenorphine.

INTRODUCTION: In the current overdose epidemic, effective treatments for opioid use disorders (OUD), including innovations in medication delivery such as extended-release formulations, have the potential to improve treatment access and reduce treatment discontinuation. This study assessed treatment retention in a primary care-based, extended-release buprenorphine program. METHODS: The study recruited individuals (n = 92) who transitioned from sublingual buprenorphine to extended-release buprenorphine (BUP-XR) in 2018-2019. The study defined the primary outcome, treatment retention, as three or more consecutive, monthly BUP-XR injections following the transition to BUP-XR in this retrospective chart review. RESULTS: Participants' mean age was 38 years old and 67% were male. The average duration of sublingual buprenorphine prior to transition was 17.1 (±28.1) months. Three months after transition, 48% of extended-release buprenorphine patients had discontinued BUP-XR treatment. Persons with chronic pain were more likely, and those who had used heroin in the past month less likely to continue BUP-XR. Mean months on sublingual buprenorphine prior to BUP-XR initiation was 24.3 (±32.5) months for people who received 3+ post-induction injections compared to only 8.9 (±19.5) months for those who did not (p = .009). CONCLUSIONS: Extended-release buprenorphine discontinuation was high in a real-world setting. Retention continues to represent a major obstacle to treatment effectiveness, and programs need interventions with even newer MOUD formulations.

Energy Restriction Suppresses Muscle Protein Synthesis, and High Protein Diets Extend Protein Half-Lives Across the Muscle Proteome in Obese Female Zucker Rats.

BACKGROUND: Effects of high protein (HP) diets and prolonged energy restriction (ER) on integrated muscle protein kinetics have not been determined. OBJECTIVE: The objective of this study was to measure protein kinetics in response to prolonged ER and HP on muscle protein synthesis (MPS; absolute rates of synthesis) and muscle protein breakdown (MPB; half-lives) for proteins across the muscle proteome. METHODS: Female 6-wk-old obese Zucker rats (Leprfa+/fa+, n = 48) were randomly assigned to one of four diets for 10 wk: ad libitum-standard protein (AL-SP; 15% kcal from protein), AL-HP (35% kcal from protein), ER-SP, and ER-HP (both fed 60% feed consumed by AL-SP). During week 10, heavy/deuterated water (2H2O) was administered by intraperitoneal injection, and isotopic steady-state was maintained via 2H2O in drinking water. Rats were euthanized after 1 wk, and mixed-MPS as well as fractional replacement rate (FRR), relative concentrations, and half-lives of individual muscle proteins were quantified in the gastrocnemius. Data were analyzed using 2-factor (energy × protein) ANOVAs and 2-tailed t-tests or binomial tests as appropriate. RESULTS: Absolute MPS was lower in ER than AL for mixed-MPS (-29.6%; P < 0.001) and MPS of most proteins measured [23/26 myofibrillar, 48/60 cytoplasmic, and 46/60 mitochondrial (P < 0.05)], corresponding with lower gastrocnemius mass in ER compared with AL (-29.4%; P < 0.001). Although mixed-muscle protein half-life was not different between groups, prolonged half-lives were observed for most individual proteins in HP compared with SP in ER and AL (P < 0.001), corresponding with greater gastrocnemius mass in HP than SP (+5.3%; P = 0.043). CONCLUSIONS: ER decreased absolute bulk MPS and most individual MPS rates compared with AL, and HP prolonged half-lives of most proteins across the proteome. These data suggest that HP, independent of energy intake, may reduce MPB, and reductions in MPS may contribute to lower gastrocnemius mass during ER by reducing protein deposition in obese female Zucker rats.

Negative affect-associated drug refusal self-efficacy, illicit opioid use, and medication use following short-term inpatient opioid withdrawal management.

INTRODUCTION: Persons with opioid use disorder (OUD) are prone to frequent relapse following brief inpatient medically managed withdrawal. This longitudinal, naturalistic study examines associations among illicit opioid use, use of medication for opioid use disorder (MOUD), and one's confidence in the ability to resist drug use in the face of negative emotions (i.e., negative affect-associated drug refusal self-efficacy). METHOD: Participants were 220 adults with OUD who recently completed a short-term inpatient program and the study followed for 6 months. At baseline, participants reported demographics, illicit opioid use, recent engagement with MOUD, and negative affect-associated drug refusal self-efficacy. At follow-up (1 week and 1-, 3-, and 6-months following discharge), participants reported illicit opioid use and MOUD. RESULTS: Participants averaged 30.7 years of age, 63.2% were male, and 84.1% were white. Both illicit opioid use and rates of MOUD increased during the 6-month follow-up period, although only 34.1% received MOUD. At baseline, participants reported less than 50% self-confidence to resist using opioids during negative emotional states. Baseline negative affect-associated drug refusal self-efficacy inversely predicted illicit opioid use (p = .01) at follow-up but was not associated with follow-up MOUD. CONCLUSION: Among persons with OUD, lower confidence to resist using opioids in negative emotional states predicts greater use of illicit opioids in the months following medically managed withdrawal, even with receipt of MOUD.

A randomized controlled trial of a brief behavioral intervention to reduce skin and soft tissue infections among people who inject drugs.

BACKGROUND: People who inject drugs (PWID) are at high risk for skin and soft tissue infections (SSTIs), but few interventions have targeted their reduction. The goal of the current study was to test the effects of a brief skin and needle hygiene behavioral intervention (SKIN) in a two-group randomized controlled trial with 12-month follow-up. METHOD: PWID (N = 252) were recruited from inpatient hospital units at a single urban medical center site and randomly assigned to an assessment-only (AO) condition or SKIN, which was a two-session intervention that included psychoeducation, behavioral skills demonstrations, and motivational interviewing. Mixed effects generalized linear models assessed the impact of the intervention on frequency of: 1) self-reported SSTIs, 2) uncleaned skin injections, and 3) injection. RESULTS: Participants were 58.3 % male, 59.5 % White, and averaged 38 years of age. SKIN participants had 35 % fewer SSTIs compared to AO (p = .179), a difference of nearly one infection per year. The mean rate of uncleaned skin injections was about 66 % lower (IRR = 0.34, 95 % CI 0.20; 0.59, p < .001) among SKIN participants compared to AO. Almost one-third of participants reported no injection over follow-up and the mean rate of injection during follow-up was about 39 % lower (IRR = 0.61; 95 % CI 0.36; 1.02, p = .058) among persons randomized to SKIN than AO. CONCLUSIONS: The SKIN intervention reduced uncleaned skin injections but did not reduce SSTIs significantly more than a control condition. Brief interventions can improve high-risk practices among PWID and lead to clinically meaningful outcomes.

Examining Overdose and Homelessness as Predictors of Willingness to Use Supervised Injection Facilities by Services Provided Among Persons Who Inject Drugs.

BACKGROUND AND OBJECTIVES: Internationally, supervised injection facilities (SIFs) have demonstrated efficacy in reducing rates of overdose and promoting entry into treatment among persons who inject drugs (PWID); however, they remain unavailable in the United States. Early findings examining American PWID illustrate high overall willingness to use SIFs. The current study expands upon this research by examining PWID's likelihood to use SIFs based on services offered (eg, provides clean needles, linkage to treatment programs) and whether known risk factors (prior overdose, homelessness) influence PWID's willingness to use a SIF. METHODS: Participants (n = 184) were patients entering short-term inpatient opioid withdrawal management in Massachusetts between May 2018 and February 2019 who reported injection drug use in the prior 30 days. We examined PWID's likelihood to use a SIF if eight unique services were available, and compared if this differed by overdose history and homelessness status using ordered logistic regression and Pearson's χ2 -tests of independence. RESULTS: Participants (34.2 [±8.3 SD] years of age, 68.5% male, 85.9% white, 8.2% Hispanic) reported being most likely to use SIFs that provided safety from police intervention (86.7%), entry into withdrawal management (85.9%), or clean needles (83.2%). Drug works disposal and safety from police were particularly important for PWID with a history of overdose. CONCLUSION AND SCIENTIFIC SIGNIFICANCE: Overall, treatment-seeking PWIDs reported greater willingness to utilize SIFs if particular services were provided. These findings point to features of SIFs that may enhance treatment-seeking PWID's amenability to utilizing these services if such sites open in the United States. (Am J Addict 2021;30:21-25).

A Randomized Trial Comparing Brief Advice and Motivational Interviewing for Persons with HIV-HCV Co-infection Who Drink Alcohol.

Alcohol use contributes to the progression of liver disease in HIV-HCV co-infected persons, but alcohol interventions have never addressed low levels of alcohol use in this population. We enrolled 110 persons consuming at least 4 alcoholic drinks weekly in a clinical trial comparing two active 18-month long interventions, delivered every 3 months by phone, brief advice about drinking versus a motivational intervention. Final assessment was at 24 months. MI had larger reductions in alcohol use days than the BA arm at all follow-up assessments. The treatment by time effect was not significant for days of drinking (p = 0.470), mean drinks per day (p = 0.155), or for the continuous FIB-4 index (p = 0.175). Drinking declined in both conditions from baseline, but given the small sample, we do not have sufficient data to make any conclusion that one treatment is superior to the other.Trial Registry Trial registered at clinicaltrials.gov; Clinical Trial NCT02316184.

Self-Control, Opportunity, and College Students' Bystander Intervention in Sexually Coercive Situations.

This study examines students' bystander intervention opportunities and behaviors using survey data from a convenience sample of 226 college students from a university in the United States. We approach this study with theoretical concepts from the criminological literature on positive peer influence, self-control theories, and social control theories. Bivariate correlations and logistic analysis reveal, contrary to our predictions, that social and self-control have only minor predictive power on the likelihood of witnessing and intervening in sexually coercive events. However, we find strong support for some demographic characteristics, peer relationships, and behavioral characteristics (such as binge drinking) as predictive of witnessing a sexually coercive event and intervening in an event. Our study adds to the literature on bystander intervention behavior and aims to inform bystander intervention programming efforts by identifying student populations that are more likely to have the opportunity to intervene in sexually coercive situations and sexual assaults.

Skin-cleaning among hospitalized people who inject drugs: a randomized controlled trial.

AIMS: To test the hypothesis that among hospitalized people who inject drugs (PWID), a brief intervention in skin-cleaning would result in greater reductions in follow-up emergency department (ED) or hospitalization rates compared with a usual care condition. DESIGN: Randomized, two-group (intervention, n = 128; usual care, n = 124), single-site clinical trial with12-month follow-up. SETTING: Hospital inpatient services in Boston, Massachusetts, United States. PARTICIPANTS: People who injected drugs on at least 3 days each week prior to hospital admission (n = 252). Participants averaged 37.9 (± 10.7) years of age; 58.5% were male, 59.3% were white and 61.1% had a diagnosis related to skin infection at enrollment. INTERVENTION AND COMPARATOR: Intervention was a skin hygiene education and skills-training behavioral intervention [short-term efficacy data on a behavioral intervention (SKIN)] consisting of two education- and skills-based skin-cleaning sessions, one during hospitalization and another 4 weeks later. The comparator was treatment as usual: an informational brochure about substance use treatment options and needle exchange programs in the area and follow-up clinical appointments as arranged by the inpatient medical staff. MEASUREMENTS: Electronic medical records were reviewed and discharge diagnoses for each ED visit and hospital admission were categorized into injection-related bacterial events (e.g. cellulitis) and non-injection-related events. Negative binomial regression was used to test the intervention effects for the primary outcome and total ED visits, as well as the secondary outcomes, total number of hospitalizations, injection drug use-related (IDU-related) ED visits and IDU-related hospitalizations. We also tested whether the outcomes were moderated by whether the initial hospitalization was IDU-related. FINDINGS: Of people assigned to SKIN, 66 completed two sessions, 55 completed one session and seven completed zero sessions. Adjusting for baseline covariates, the mean rate of total ED visits in the next 12 months was non-significantly higher [incidence rate ratio (IRR) = 1.13, 95% confidence interval (CI) = 0.96, 1.33, P = 0.152] compared with usual treatment. The intervention did not significantly reduce total hospitalizations or IDU-related hospitalizations. Adjusting for baseline covariates, the mean rate of injection drug use-related ED visits in the next 12 months was lower (IRR = 0.57, 95% CI = 0.35, 0.91, P = 0.019) compared with treatment as usual. CONCLUSIONS: A skin-cleaning intervention for people who inject drugs delivered during a hospitalization did not significantly reduce either overall emergency department use or hospitalization. There was some evidence that it may have reduced injection drug use-related emergency department visits.

Longitudinal examination of coping-motivated marijuana use and problematic outcomes among emerging adults.

OBJECTIVE: Cross-sectional research shows that coping-motivated marijuana use is associated with marijuana use and problems. However, limited research has examined how coping-motivated use might longitudinally relate to these outcomes. We examined the temporal relationship of coping-motivated marijuana use with severity of use and marijuana-related problems. METHOD: Participants were 226 emerging adults, aged 18-25 years old, who currently used marijuana. Multilevel generalized linear models were used to evaluate the association between change in coping motives with change in frequency of marijuana use and marijuana problem severity from baseline to 6- and 12-month follow-ups. RESULTS: In the adjusted models, frequency of marijuana use was positively associated with between subject differences (IRR = 1.49; 95%CI: 1.30, 1.71; p < .001) but not within subject change over time (IRR = 1.09; 95%CI: 0.97, 1.22; p = .139) in use of marijuana to cope. Additionally, marijuana problem severity scores were associated positively with between subject differences (IRR = 1.45; 95%CI: 1.21, 1.75; p < .001) and within subject changes over time (IRR = 1.30; 95%CI: 1.07, 1.57; p < .01) in use of marijuana to cope. CONCLUSIONS: Changes in coping-motivated use of marijuana in emerging adults were directionally associated with changes in marijuana use and marijuana problems up to 12 months post-baseline. Results highlight the possible bi-directional relationship between coping motives and marijuana use and problems. Findings could be valuable in helping practitioners go beyond quantity and frequency as sufficient metrics of marijuana use problems. Motives for use may reflect additional problems and the clinical need to explore these possibilities.
