Background: Significant disparities in substance use severity and treatment persist among women who use drugs compared to men. Thus, we explored how identifying as a woman was related to drug use and treatment experiences., Methods: The study recruited participants for a qualitative interview study in Boston and San Francisco from January-November 2020. Self-identified women, age ≥ 18 years, with nonprescribed opioid use in the past 14 days were eligible for inclusion. The study team developed deductive codes based on intersectionality theory and inductive codes generated from transcript review, and identified themes using grounded content analysis., Results: The study enrolled thirty-six participants. The median age was 46; 58 % were White, 16 % were Black, 14 % were Hispanic, and 39 % were unstably housed. Other drug use was common with 81 % reporting benzodiazepine, 50 % cocaine, and 31 % meth/amphetamine use respectively. We found that gender (i.e., identifying as a woman) intersected with drug use and sex work practices and exacerbated experiences of marginalization. Violence was ubiquitous in drug use environments. Some women reported experiences of gender-based violence in substance use service settings that perpetuated cycles of trauma and reinforced barriers to care. Substance use services that were women-led, safe, and responsive to women's needs were valued and sought after., Conclusion: Women reported a cycle of trauma and drug use exacerbated by oppression in substance use services settings. In addition to increasing access to gender-responsive care, our study highlights the need for greater research and examination of practices within substance use service settings that may be contributing to gender-based violence., Competing Interests: Declaration of competing interest None declared., (Copyright © 2023 Elsevier Inc.

Background: Post-overdose outreach programs have proliferated in response to opioid overdose. Implementing these programs is associated with reductions in overdose rates, but the role of specific program characteristics in overdose trends has not been evaluated., Methods: Among 58 Massachusetts municipalities with post-overdose outreach programs, we examined associations between five domains of post-overdose outreach program characteristics (outreach contact rate, naloxone distribution, coercive practices, harm reduction activities, and social service provision or referral) and rates of fatal opioid overdoses and opioid-related emergency medical system responses (i.e., ambulance activations) per calendar quarter from 2013 to 2019 using segmented regression analyses with adjustment for municipal covariates and fixed effects. For both outcomes, each domain was modeled: a) individually, b) with other characteristics, and c) with other characteristics and municipal-level fixed effects., Results: There were no significant associations (p < 0.05) between outreach contact rate, naloxone distribution, coercive practices, or harm reduction activities with municipal fatal overdose trends. Municipalities with programs providing or referring to more social services experienced 21% fewer fatal overdoses compared to programs providing or referring to more social services (Rate Ratio (RR) 0.79, 95% Confidence Interval (CI) 0.66-0.93, p = 0.01). Compared to municipalities in quarters when programs had no outreach contacts, municipalities with some, but less than the median outreach contacts, experienced 14% lower opioid-related emergency responses (RR 0.86, 95% CI 0.78-0.96, p = 0.01). Associations between naloxone distribution, coercive practices, harm reduction practices, or social services and opioid-related emergency responses were not consistently significant across modeling approaches., Conclusion: Municipalities with post-overdose outreach programs providing or referring to more social services had lower fatal opioid overdose rates. Municipalities in quarters when programs outreached to overdose survivors had fewer opioid-related emergency responses, but only among programs with below the median number of outreach contacts. Social service linkage should be core to post-overdose programs. Evaluations should assess program characteristics to optimize program design., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Drs.

Importance: Nonfatal opioid overdose is the leading risk factor for subsequent fatal overdose and represents a critical opportunity to reduce future overdose and mortality. Postoverdose outreach programs emerged in Massachusetts beginning in 2013 with the main purpose of linking opioid overdose survivors to addiction treatment and harm reduction services., Objective: To evaluate whether the implementation of postoverdose outreach programs among Massachusetts municipalities was associated with lower opioid fatality rates compared with municipalities without postoverdose outreach programs., Design, Setting, and Participants: This retrospective interrupted time-series analysis was performed over 26 quarters (from January 1, 2013, through June 30, 2019) across 93 municipalities in Massachusetts. These 93 municipalities were selected based on a threshold of 30 or more opioid-related emergency medical services (EMS) responses in 2015. Data were analyzed from November 2021 to August 2022., Exposures: The main exposure was municipality postoverdose outreach programs. Municipalities had various program inceptions during the study period., Main Outcomes and Measures: The primary outcome was quarterly municipal opioid fatality rate per 100 000 population. The secondary outcome was quarterly municipal opioid-related EMS response (ambulance trips) rates per 100 000 population., Results: The mean (SD) population size across 93 municipalities was 47 622 (70 307), the mean (SD) proportion of female individuals was 51.5% (1.5%) and male individuals was 48.5% (1.5%), and the mean (SD) age proportions were 29.7% (4.0%) younger than 25 years, 26.0% (4.8%) aged 25 to 44 years, 14.8% (2.1%) aged 45 to 54 years, 13.4% (2.1%) aged 55 to 64 years, and 16.1% (4.4%) aged 65 years or older. Postoverdose programs were implemented in 58 municipalities (62%). Following implementation, there were no significant level changes in opioid fatality rate (adjusted rate ratio [aRR], 1.07; 95% CI, 0.96-1.19; P = .20). However, there was a significant slope decrease in opioid fatality rate (annualized aRR, 0.94; 95% CI, 0.90-0.98; P = .003) compared with the municipalities without the outreach programs. Similarly, there was a significant slope decrease in opioid-related EMS response rates (annualized aRR, 0.93; 95% CI, 0.89-0.98; P = .007). Several sensitivity analyses yielded similar findings., Conclusions and Relevance: In this study, among Massachusetts municipalities with high numbers of opioid-related EMS responses, implementation of postoverdose outreach programs was significantly associated with lower opioid fatality rates over time compared with municipalities that did not implement such programs. Program components, including cross-sectoral partnerships, operational best practices, involvement of law enforcement, and related program costs, warrant further evaluation to enhance effectiveness.

Dryland riparian woodlands are considered to be locally buffered from droughts by shallow and stable groundwater levels. However, climate change is causing more frequent and severe drought events, accompanied by warmer temperatures, collectively threatening the persistence of these groundwater dependent ecosystems through a combination of increasing evaporative demand and decreasing groundwater supply. We conducted a dendro-isotopic analysis of radial growth and seasonal (semi-annual) carbon isotope discrimination (Δ 13 C) to investigate the response of riparian cottonwood stands to the unprecedented California-wide drought from 2012 to 2019, along the largest remaining free-flowing river in Southern California. Our goals were to identify principal drivers and indicators of drought stress for dryland riparian woodlands, determine their thresholds of tolerance to hydroclimatic stressors, and ultimately assess their vulnerability to climate change. Riparian trees were highly responsive to drought conditions along the river, exhibiting suppressed growth and strong stomatal closure (inferred from reduced Δ 13 C) during peak drought years. However, patterns of radial growth and Δ 13 C were quite variable among sites that differed in climatic conditions and rate of groundwater decline. We show that the rate of groundwater decline, as opposed to climate factors, was the primary driver of site differences in drought stress, and trees showed greater sensitivity to temperature at sites subjected to faster groundwater decline. Across sites, higher correlation between radial growth and Δ 13 C for individual trees, and higher inter-correlation of Δ 13 C among trees were indicative of greater drought stress. Trees showed a threshold of tolerance to groundwater decline at 0.5 m year -1 beyond which drought stress became increasingly evident and severe. For sites that exceeded this threshold, peak physiological stress occurred when total groundwater recession exceeded ~3 m. These findings indicate that drought-induced groundwater decline associated with more extreme droughts is a primary threat to dryland riparian woodlands and increases their susceptibility to projected warmer temperatures., (© 2022 The Authors.

Background: Drug overdose mortality continues to increase, now driven by fentanyl. Prevention tools such as naloxone and medications to treat opioid use disorder are not sufficient to control overdose rates; additional strategies are urgently needed., Objective: We sought to adapt a behavioral intervention to prevent opioid overdose (repeated-dose behavioral intervention to reduce opioid overdose [REBOOT]) that had been successfully piloted in San Francisco, California, United States, to the setting of Boston, Massachusetts, United States, and the era of fentanyl for a full efficacy trial., Methods: We used the assessment, decision, adaptation, production, topical experts, integration, training, and testing (ADAPT-ITT) framework for intervention adaptation. We first identified opioid overdose survivors who were actively using opioids as the population of interest and REBOOT as the intervention to be adapted. We then performed theater testing and elicited feedback with 2 focus groups (n=10) in Boston in 2018. All participants had used opioids that were not prescribed to them in the past year and experienced an opioid overdose during their lifetime. We incorporated focus group findings into our initial draft of the adapted REBOOT intervention. The adapted intervention was reviewed by 3 topical experts, and their feedback was integrated into a subsequent draft. We trained study staff on the intervention and made final refinements based on internal piloting. This paper describes the overall ADAPT-ITT process for intervention adaptation, as well as a qualitative analysis of the focus groups. Working independently, 2 authors (VMM and JA) reviewed the focus group transcripts and coded them for salient and common themes using the constant comparison method, meeting to discuss any discrepancies until consensus was reached. Codes and themes were then mapped onto the REBOOT counseling steps., Results: Focus group findings contributed to substantial changes in the counseling intervention to better address fentanyl overdose risk. Participants described the widespread prevalence of fentanyl and said that, although they tried to avoid it, avoidance was becoming impossible. Using alone and lower opioid tolerance were identified as contributors to overdose risk. Slow shots or tester shots were acceptable and considered effective to reduce risk. Naloxone was considered an effective reversal strategy. Although calling emergency services was not ruled out, participants described techniques to prevent the arrival of police on the scene. Expert review and internal piloting improved the intervention manual through increased participant centeredness, clarity, and usability., Conclusions: We successfully completed the ADAPT-ITT approach for an overdose prevention intervention, using theater testing with people who use opioids to incorporate the perspectives of people who use drugs into a substance use intervention. In the current crisis, overdose prevention strategies must be adapted to the context of fentanyl, and innovative strategies must be deployed, including behavioral interventions., Trial Registration: ClinicalTrials.gov NCT03838510; https://clinicaltrials.gov/ct2/show/NCT03838510., (©Vanessa M McMahan, Justine Arenander, Tim Matheson, Audrey M Lambert, Sarah Brennan, Traci C Green, Alexander Y Walley, Phillip O Coffin.

Background: Severe mental illness (SMI; schizophrenia, bipolar disorders (BDs), and other nonorganic psychoses) is associated with increased risk of cardiovascular disease (CVD) and CVD-related mortality. To date, no systematic review has investigated changes in population level CVD-related mortality over calendar time. It is unclear if this relationship has changed over time in higher-income countries with changing treatments., Methods and Findings: To address this gap, a systematic review was conducted, to assess the association between SMI and CVD including temporal change. Seven databases were searched (last: November 30, 2021) for cohort or case-control studies lasting ≥1 year, comparing frequency of CVD mortality or incidence in high-income countries between people with versus without SMI. No language restrictions were applied. Random effects meta-analyses were conducted to compute pooled hazard ratios (HRs) and rate ratios, pooled standardised mortality ratios (SMRs), pooled odds ratios (ORs), and pooled risk ratios (RRs) of CVD in those with versus without SMI. Temporal trends were explored by decade. Subgroup analyses by age, sex, setting, world region, and study quality (Newcastle-Ottawa scale (NOS) score) were conducted. The narrative synthesis included 108 studies, and the quantitative synthesis 59 mortality studies (with (≥1,841,356 cases and 29,321,409 controls) and 28 incidence studies (≥401,909 cases and 14,372,146 controls). The risk of CVD-related mortality for people with SMI was higher than controls across most comparisons, except for total CVD-related mortality for BD and cerebrovascular accident (CVA) for mixed SMI. Estimated risks were larger for schizophrenia than BD. Pooled results ranged from SMR = 1.55 (95% confidence interval (CI): 1.33 to 1.81, p < 0.001), for CVA in people with BD to HR/rate ratio = 2.40 (95% CI: 2.25 to 2.55, p < 0.001) for CVA in schizophrenia. For schizophrenia and BD, SMRs and pooled HRs/rate ratios for CHD and CVD mortality were larger in studies with outcomes occurring during the 1990s and 2000s than earlier decades (1980s: SMR = 1.14, 95% CI: 0.57 to 2.30, p = 0.71; 2000s: SMR = 2.59, 95% CI: 1.93 to 3.47, p < 0.001 for schizophrenia and CHD) and in studies including people with younger age. The incidence of CVA, CVD events, and heart failure in SMI was higher than controls. Estimated risks for schizophrenia ranged from HR/rate ratio 1.25 (95% CI: 1.04 to 1.51, p = 0.016) for total CVD events to rate ratio 3.82 (95% CI: 3.1 to 4.71, p < 0.001) for heart failure. Incidence of CHD was higher in BD versus controls. However, for schizophrenia, CHD was elevated in higher-quality studies only. The HR/rate ratios for CVA and CHD were larger in studies with outcomes occurring after the 1990s. Study limitations include the high risk of bias of some studies as they drew a comparison cohort from general population rates and the fact that it was difficult to exclude studies that had overlapping populations, although attempts were made to minimise this., Conclusions: In this study, we found that SMI was associated with an approximate doubling in the rate ratio of CVD-related mortality, particularly since the 1990s, and in younger groups. SMI was also associated with increased incidence of CVA and CHD relative to control participants since the 1990s. More research is needed to clarify the association between SMI and CHD and ways to mitigate this risk., Competing Interests: I have read the journal’s policy and the authors of this manuscript have the following competing interests: CUC has been a consultant and/or advisor to or has received honoraria from: AbbVie, Acadia, Alkermes, Allergan, Angelini, Aristo, Axsome, Damitsa, Gedeon Richter, Hikma, IntraCellular Therapies, Janssen/J&J, Karuna, LB Pharma, Lundbeck, MedAvante-ProPhase, MedInCell, Medscape, Merck, Mitsubishi Tanabe Pharma, Mylan, Neurocrine, Noven, Otsuka, Pfizer, Recordati, Rovi, Servier, Sumitomo Dainippon, Sunovion, Supernus, Takeda, Teva, and Viatris.

Introduction: We conducted a qualitative study to explore the impact of the COVID-19 pandemic on experiences with addiction treatment and harm reduction services., Methods: The study recruited participants from Boston, Massachusetts, aged 18-65 who had a history of opioid use disorder and overdose, from a parent study (REpeated dose Behavioral intervention to reduce Opioid Overdose, REBOOT) to participate between August and October 2020. In-depth individual interviews explored the impact of the COVID-19 pandemic on addiction service experiences. We conducted a grounded content analysis that examined codes related to addiction service access and engagement during the pandemic to compare and categorize participants according to their experiences., Results: The study enrolled twenty participants. The mean age was 42 years; most identified as white (n = 16); ten participants identified as men, nine as cis-gender women, and one as a trans-gender woman. Participants described their experiences with COVID-19-driven changes to addiction care (methadone take homes, televisits for either buprenorphine or behavioral health services, and syringe service outreach) access and engagement as: 1) liberating (n = 7), 2) destabilizing (n = 8), or 3) unjust (n = 5). Participants in the liberating group found adaptations allowed for increased flexibility, freedom, and safety from COVID-19. This group was mostly housed and had strong social supports that facilitated participation in adapted treatment programs. COVID-19-related changes to addiction treatment disrupted routine and community supports among those in the destabilizing group. Participants in the unjust group felt that adaptations exacerbated inequities as a lack of housing and other social supports prohibited them from benefiting from the relaxed restrictions to methadone or buprenorphine. This group was mostly unhoused and found that adaptations did not adequately mitigate other inequities worsened by public health mandates for unhoused people who use drugs., Conclusion: Relaxed restrictions on medications for opioid use disorder created opportunities for improved patient-centered care. Concrete measures that address service barriers, such as phone or transportation access, may have reduced destabilizing and unjust experiences reported by our participants. However, addiction care inequities will persist if drivers of marginalization, specifically a lack of housing, remain unaddressed., (Copyright © 2021. Published by Elsevier Inc.)

Background: Post-overdose outreach programs engage survivors in harm reduction and treatment to prevent future overdoses. In Massachusetts, these emerging programs commonly deploy teams comprised of police and public health professionals based on 911 call information. Some teams use name/address data to conduct arrest warrant checks prior to outreach visits. We used mixed methods to understand approaches to outreach related to warrant checking, from the perspectives of police and public health outreach agencies and staff., Methods: We analyzed a 2019 statewide survey of post-overdose outreach programs in Massachusetts to classify approaches to warrant checking and identify program and community factors associated with particular approaches. Ethnographic analysis of qualitative interviews conducted with outreach staff helped further contextualize outreach program practices related to warrants., Results: A majority (57% - 79/138) of post-overdose outreach programs in Massachusetts conducted warrant checks prior to outreach. Among programs that checked warrants, we formulated a taxonomy of approaches to handling warrants: 1) performing outreach without addressing warrants (19.6% - 27/138), 2) delaying outreach until warrants are cleared (15.9% - 22/138), 3) arresting the survivor (11/138 - 8.0%), 4) taking a situational approach (10/138 - 7.2%), 5) not performing outreach (9/138 - 6.5%). Program characteristics and staff training did not vary across approaches. From police and public health outreach staff interviews (n = 38), we elicited four major themes: a) diverse motivations precede warrant checking, b) police officers feel tension between dual roles, c) warrants alter approaches to outreach, and d) teams leverage warrants in relationships. Findings from both analyses converged to demonstrate unintended consequences of warrant checking., Conclusion: Checking warrants prior to post-overdose outreach visits can result in arrest, delayed outreach, and barriers to obtaining services for overdose survivors, which can undermine the goal of these programs to engage overdose survivors. With the public health imperative of engaging overdose survivors, programs should consider limiting warrant checking and police participation in field activities., Competing Interests: Declarations of Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: AYW is the medical director of overdose prevention programs at the Massachusetts Department of Public health and signs the statewide naloxone standing order, including multiple police and fire departments in Massachusetts., (Copyright © 2021.

Background: Naloxone is a prescription medication that reverses opioid overdoses. Allowing naloxone to be dispensed directly by a pharmacist without an individual prescription under a naloxone standing order (NSO) can expand access. The community-level factors associated with naloxone dispensed under NSO are unknown., Methods: Using a dataset comprised of pharmacy reports of naloxone dispensed under NSO from 70% of Massachusetts retail pharmacies, we examined relationships between community-level demographics, rurality, measures of treatment for opioid use disorder, and overdose deaths with naloxone dispensed under NSO per ZIP Code-quarter from 2014 until 2018. We used a multi-variable zero-inflated negative binomial model, assessing odds of any naloxone dispensed under NSO, as well as a multi-variable negative binomial model assessing quantities of naloxone dispensed under NSO., Results: From 2014-2018, quantities of naloxone dispensed under NSO and the number of pharmacies dispensing any naloxone under NSO increased over time. However, communities with greater percentages of people with Hispanic ethnicity (aOR 0.91, 95% CI 0.86-0.96 per 5% increase), and rural communities compared to urban communities (aOR 0.81, 95% CI 0.73-0.90) were less likely to dispense any naloxone by NSO. Communities with more individuals treated with buprenorphine dispensed more naloxone under NSO, as did communities with more opioid-related overdose deaths., Conclusion: Naloxone dispensing has substantially increased, in part driven by standing orders. A lower likelihood of naloxone being dispensed under NSO in communities with larger Hispanic populations and in more rural communities suggests the need for more equitable access to, and uptake of, lifesaving medications like naloxone., (Copyright © 2021 Elsevier B.V.

This study examined the performance of Poanes viator (Edwards) (Hesperiidae), a native North American skipper, and Rhizedra lutosa (Hübner) (Noctuidae), an introduced moth, reared on native and non-native, invasive lineages of Phragmites australis . Poanes viator is a generalist on monocots and larvae were also fed leaves of Zizania aquatica , a native macrophyte that the skipper commonly uses as a host plant. Larval survival and duration, pupal weight, and pupation time were compared for P. viator feeding on leaf tissue and R. lutosa feeding on rhizomes of either native or introduced plants. We also tested an artificial diet supplemented with P. australis rhizome powder as a potential food for rearing other stalk and rhizome boring Lepidoptera. In experiments using excised plant tissues, some individuals of both species fed and developed to the pupal stage on native and introduced plants, but overall, larval survival rates were low. Plant species/haplotype identity did not cause strong differences in larval survival for either species. However, P. viator larvae only pupated when feeding on native plants ( Zizania aquatica and native P. australis haplotypes), whereas R. lutosa successfully pupated on both native and introduced P. australis . Although larval survival was low, 100% of P. viator and 95% of R. lutosa that reached the pupal stage emerged as adults. Rhizedra lutosa larvae fed an artificial diet supplemented with P. australis rhizome powder had significantly greater survival and pupal weights, and shorter pupation times than larvae fed rhizomes only. Several specialist Lepidopteran species are being considered for approval as biological control agents for the non-native P. australis haplotype, and the convenience and increased larval performance make this artificial diet a good alternative for rearing organisms.
