Interaction and conflict between outreach workers and research officers in implementing collaborative action research in the field of harm reduction: a qualitative study

BackgroundThe effectiveness of collaborative approaches in health interventions is underlined in the literature. Given the serious challenges to adequately managing the HCV epidemic in people who inject drugs (PWID), and the need to improve existing harm reduction (HR) interventions in this population, it seems important to investigate how collaboration between stakeholders is ensured in action research interventions. The present study aimed to explore interactions between outreach workers and research officers collaborating in the implementation of an action research project for PWID entitled OUTSIDER.MethodsUsing three focus groups, we studied the views of 24 outreach workers involved in the implementation and evaluation of a harm reduction educational intervention to help PWID inject more safely in off-site settings.ResultsThe analysis of participants’ discourses highlighted the mixed perceptions they had about OUTSIDER. Several limitations to collaboration emerged. Epistemological (theoretical vs. practical knowledge), methodological (science vs. intervention), axiological (standardised vs. adapted approach), and material (mobilised vs. available resources) issues all placed a burden on the outreach worker–research officer relationship. Outreach workers’ acceptance of the project’s intervention dimension but rejection of its scientific dimension highlights a lack of contractualisation between the stakeholders involved, and a more general problematisation of the role of outreach workers in implementing action research in HR. How collaboration was perceived and practised by outreach workers participating in OUTSIDER can be considered a reflection of the current challenges to implementing action research in HR.ConclusionThis study of the interaction between the research and implementation dimensions of an action research project explored the tensions between different intervention stakeholders that must work together. Equitable participation and integration of the expertise, practices, and knowledge of all stakeholders involved is essential for successful action research. Given current HCV epidemiological challenges, new forms of cooperation are needed when developing healthcare services and when strengthening collaborative approaches.

The relationship between knowledge, attitudes, and practices of community pharmacists regarding persons with substance use disorders

Background: Community pharmacists can play a meaningful role in identification and treatment of substance use disorders (SUD). However, inadequate disease knowledge and negative attitudes are known barriers. The relationship between knowledge, attitudes, and practice of pharmacists regarding persons with SUD has not been evaluated comprehensively in the United States. The objective of the study was to assess knowledge of community pharmacists regarding medications for SUD and evaluate their attitudes, levels of stigma, and clinical practices in SUD. Methods: A questionnaire was developed to assess practices, knowledge, screening services, and attitudes toward harm reduction strategies and treatment. A standardized measure of stigma was included along with demographics. A cross-sectional electronic survey was conducted in Pennsylvania, Ohio, and West Virginia among a non-probability sample of community pharmacists working for a retail pharmacy chain (n = 910) and a local alumni network (n = 50). Scores were calculated for each factor and descriptive analyses, mean differences (t-tests and ANOVA), correlations with demographics and practice characteristics were performed. Linear and ordinal regressions were utilized to predict knowledge, practice, screening, and stigma scores. Results: A total of 134 responses (response rate 13.9%) were collected. On average, the pharmacists were 38 years old, had worked for 15 years, primarily full-time with practice locations in suburban settings. Only 53% reported they received SUD education in pharmacy school. Pharmacists received a mean score of 5.5 and 3.5 out of eight and seven on knowledge and practice scales, respectively. Pharmacists overall had slightly stigmatizing and negative attitudes, with higher stigma significantly related to performing lesser services and considering screenings as important. Number of years worked significantly predicted knowledge and screening. Conclusion: Relationships between knowledge, attitudes, and practices indicate a need for experiential education that includes psychosocial aspects of care with increased opportunities for practice.

Incoming medical students’ knowledge of and attitudes toward people with substance use disorders: Implications for curricular training

Background: Medical students may be in an ideal position to identify patients with substance use disorders (SUDs) and provide them with information about harm reduction and treatment options. Specific education regarding opioid use disorder (OUD) and naloxone during undergraduate medical training may help students identify these patients and decrease their own negative attitudes toward patients with OUD. To plan for curriculum development, this study aimed to understand baseline knowledge and attitudes among students entering medical school. Methods: During orientation, all first-year medical students (Class of 2023) were asked to complete a survey that explored their previous experiences in healthcare and with SUDs as well as their attitudes toward opioid overdose and patients with SUDs. We administered the Opioid Overdose Knowledge Scale (OOKS), Opioid Overdose Attitudes Scale (OOAS), Medical Conditions Regard Scale (MCRS), and Naloxone Related Risk Compensation Beliefs (NaRRC-B). Results: 266 students (89.6% of the class) completed the survey. Generally, these students were relatively proficient in opioid overdose knowledge, but did not feel they were competent enough to respond to an overdose. Attitudes toward patients with SUDs were mixed. Approximately half of the students thought naloxone distribution should be unrestricted, but many were uncertain whether naloxone receipt would deter individuals from seeking treatment or increase opioid use. Students’ previous experiences in healthcare (e.g., employment) results in significantly different knowledge and attitudes toward opioid overdose response. Conclusions: These incoming medical students have greater healthcare experience and level of opioid overdose knowledge than the general population, but still harbor significant misinformation and stigma toward patients with SUDs. These findings provide a foundation upon which to tailor didactic efforts, starting early in medical school, so that graduating physicians can be adequately prepared for clinical care.

Analytical Challenges for Identification of New Psychoactive Substances: A Literature-Based Study for Seized Drugs

Correct identification of substances is essential to understand drug use and trafficking trends and guide measures for harm reduction and treatment. Two steps are needed to verify the nature of a substance properly: a presumptive test and a confirmatory test. There are presumptive tests which presents deficiencies, such as providing false-positive and false-negative results. Confirmatory tests are more reliable, but they are more expensive. With the appearance of New Psychoactive Substances (NPS), identifying and characterizing illicit substances has become more challenging. This paper focuses on presenting information about NPS characteristics and analysis. For this purpose, we have reviewed the literature to address the main aspects of five groups of NPS: amphetamine-type stimulants, synthetic cannabinoids, N-methoxybenzyl-methoxyphenylethylamine (NBOMe), synthetic opioids, and benzodiazepines. We present the main characteristics of each group and certain aspects of presumptive and confirmatory tests regarding these groups. Our findings show obstacles in developing methodologies that can correctly identify these substances, and problems can increase as new structures appear. This information can be helpful to drive research into identifying NPS and inform law enforcement and law practitioners about the main characteristics of each group and the main questions involving their identification.

“We have to be uncomfortable and creative”: Reflections on the impacts of the COVID-19 pandemic on overdose prevention, harm reduction & homelessness advocacy in Philadelphia

The COVID-19 pandemic and ensuing service delivery interruptions had serious impacts on people who use drugs (PWUD) and people experiencing homelessness, including instability in the drug supply, decreased access to substance use disorder (SUD) treatment and harm reduction supplies, increased substance use and relapse due to stress and isolation, inability to properly isolate and quarantine without stable housing, and risk of COVID-19 spread in congregate living spaces. At the same time, many have noted a potential opportunity for rapid change in health, housing, and drug policy despite previous stagnation—referred to as a “punctuated equilibrium” by Baumgartner and Jones—in response to the pandemic. The pandemic forced some important policy interventions in the United States at both national and local levels, including eviction moratoriums and loosening of drug policy related to substance use treatment. However, to what extent some of these changes will be sustained past the current COVID-19 crisis is still unclear, as is how drug and housing related policy shifts have impacted the work of frontline overdose prevention, substance use treatment, and homelessness advocacy workers. In this qualitative study, we used semi-structured interviews to assess how Philadelphia’s harm reduction advocates, community organizers, and SUD treatment clinicians have responded to the overdose and homelessness crises during COVID-19, and how they predict the pandemic and ensuing policy changes will impact the future of overdose prevention, harm reduction efforts, and homelessness advocacy. We interviewed 30 eligible participants during July and August 2020. The analysis of these data yielded three themes: 1/“None of it should be new to anybody”: COVID-era issues impacting PWUD and people experiencing homelessness are extensions of existing problems; 2/“An opportunity to actually benefit in some way from this crisis”: Possibility for innovation and improved care for PWUD and people experiencing homelessness; and 3/“Nothing we’ve tried has worked, so we have to be uncomfortable and creative”: The uncertain path forward. Despite the many barriers that participants faced to promoting the health and well-being of marginalized communities during the pandemic, they also believed that the pandemic presented an important opportunity for positive policy change that has the potential to promote drug user health into the future, including a continuation of loosened federal restrictions on substance use disorder treatment, legalization of safe consumption spaces, safe supply of substances, and progressive, creative housing solutions.

Care-engaged individuals with polysubstance use in Northeastern US are undertreated for methamphetamine use disorder: a retrospective cohort study

BackgroundStimulant use has increased across the US, with concomitant opioid and methamphetamine use doubling between 2011 and 2017. Shifting patterns of polysubstance use have led to rising psychostimulant-involved deaths. While it is known that individuals who use methamphetamine require greater access to treatment, there is still little known about methamphetamine use and treatment among individuals who are already engaged in outpatient substance use treatment.ObjectivesTo characterize care-engaged individuals who use methamphetamine to guide harm reduction and treatment strategies.MethodsRetrospective cohort study of individuals at a large academic medical center in Massachusetts with ≥ 2 positive methamphetamine oral fluid toxicology tests between August 2019 and January 2020. We performed descriptive analysis of sociodemographic, medical, and drug use characteristics and a comparative analysis of injection methamphetamine use versus other routes of use.ResultsIncluded were 71 individuals [56 male (80%), 66 non-Hispanic white (94%), median age 36 (IQR 30–42)]. Nearly all had opioid (94%) and stimulant use disorder (92%). Most had (93%) or were (83%) being treated with medications for opioid use disorder, but few received pharmacologic treatment for methamphetamine use disorder (24%). None received contingency management treatment.People who inject methamphetamine (68%) were more likely to have a history of overdose (91% vs. 70%; p = 0.02), have HCV (94% vs. 52%; p < 0.01), use fentanyl (93% vs. 65%; p = 0.02), and engage in sex work (19% vs. 0%; p = 0.03) compared to those who used via other routes. Both groups had prevalent homelessness (88% vs. 73%; p = 0.15), incarceration (81% vs. 64%; p = 0.11), depression (94% vs. 87%; p = 0.34), and bacteremia (27% vs. 22%; p = 0.63).ConclusionsIndividuals in our study had high prevalence of polysubstance use, particularly concomitant methamphetamine and opioid use. Individuals who were well connected to substance use treatment for their opioid use were still likely to be undertreated for their methamphetamine use disorder and would benefit from greater access to contingency management treatment, harm reduction resources, and resources to address adverse social determinants of health.

Social vulnerability and the impact of policy responses to COVID-19 on disabled people.

In this paper, we propose a conceptual framework for understanding the impact of the policy responses to COVID‐19 on disabled people. These responses have overwhelmingly focused on individual vulnerability, which has been used as a justification for removing or restricting rights. This suggests the need to shift the attention towards the social determinants of disabled people's vulnerability. We do this by bringing literature on social vulnerability in disaster risk management or ‘disaster studies’ in contact with key concepts in disability studies such as the social model of disability, independent living, intersectionality, and biopower. Empirically, we draw on the findings of the global COVID‐19 Disability Rights Monitor (www.covid‐drm.org), as well as on reports from academic journals, civil society publications, and internet blogs. We put the proposed conceptual framework to work by developing a critical analysis of COVID‐19 policies in three interrelated areas—institutional treatment and confinement of disabled people, intersectional harms, and access to health care. Our conclusion links this analysis with strategies to address disabled people's social vulnerability in post‐pandemic reconstruction efforts. We make a case for policies that address the social, economic, and environmental conditions that disproportionately expose disabled people to natural disasters and hazards.

Titanium and Iron Oxide Nanoparticles for Cancer Therapy: Surface Chemistry and Biological Implications

Currently, cancer is among the most challenging diseases due to its ability to continuously evolve into a more complex muldimentional system, in addition to its high capability to spread to other organs and tissues. In this context, the relevance of nanobiomaterials (NBMs) for the development of new more effective and less harmful treatments is increasing. NBMs provide the possibility of combining several functionalities on a single system, expectedly in a synergic way, to better perform the treatment and cure. However, the control of properties such as colloidal stability, circulation time, pharmacokinetics, and biodistribution, assuring the concentration in specific target tissues and organs, while keeping all desired properties, tends to be dependent on subtle changes in surface chemistry. Hence, the behavior of such materials in different media/environments is of uttermost relevance and concern since it can compromise their efficiency and safety on application. Given the bright perspectives, many efforts have been focused on the development of nanomaterials fulfilling the requirements for real application. These include robust and reproducible preparation methods to avoid aggregation while preserving the interaction properties. The possible impact of nanomaterials in different forms of diagnosis and therapy has been demonstrated in the past few years, given the perspectives on how revolutionary they can be in medicine and health. Considering the high biocompatibility and suitability, this review is focused on titanium dioxide– and iron oxide–based nanoagents highlighting the current trends and main advancements in the research for cancer therapies. The effects of phenomena, such as aggregation and agglomeration, the formation of the corona layer, and how they can compromise relevant properties of nanomaterials and their potential applicability, are also addressed. In short, this review summarizes the current understanding and perspectives on such smart nanobiomaterials for diagnostics, treatment, and theranostics of diseases.

Accuracy of magnetic resonance imaging staging of tumour and nodal stage in rectal cancer treated by primary surgery: a population-based study.

The preoperative stage of rectal cancer is an important prognostic factor affecting treatment recommendations. Currently, magnetic resonance imaging (MRI) is used for clinical staging to identify patients who should be recommended for neoadjuvant oncological treatment. The aim of this work was to investigate the accuracy of the preoperative T- and N-stage and also involvement of the mesorectal fascia (MRF) as determined by MRI in a Swedish national cohort. Patients who had undergone resectional surgery for rectal cancer without neoadjuvant treatment in Sweden in the period 2013-2017 were identified through the Swedish Colorectal Cancer Registry (n=2062). The T- and N-stage determined by preoperative MRI were compared with the histopathological results. The MRI-assessed MRF status was compared with the circumferential resection margin. Sensitivity for differentiating T1-2 from T3-4 was 69% and specificity 77%. Sensitivity to detect N1-2 was 42% and specificity 81%. Sensitivity for MRF positivity was 50% and specificity 92%. Agreement analysed by weighted kappa analysis was 0.47 for T-stage [confidence interval (CI) 0.44-0.51], 0.24 for N-stage (CI 0.19-0.24) and 0.20 for MRF status (CI 0.12-0.29). In this study, accuracy of the preoperative MRI was lower than expected for rectal cancers. Overstaging might lead to potentially harmful neoadjuvant treatment and understaging can lead to a higher risk of tumour recurrence. The results of this study show that efforts should be made to increase the accuracy of the preoperative evaluation in order to optimize treatment recommendations.

A Systematic Review of Internet Delivered Interventions for Gambling: Prevention, Harm Reduction and Early Intervention.

Internet delivered interventions are accessible and easy to access and can be used to deliver brief interventions. These interventions can be tailored according to individual need for the prevention and minimisation of gambling harm or early intervention for those that are displaying some signs of problems. The objective of this review was to summarise the existing literature on the effectiveness of prevention, harm reduction and early intervention programs when delivered online. A systematic review was conducted for peer-reviewed studies that evaluated internet delivered interventions for the prevention, harm reduction or early intervention for gambling problems. Four electronic databases were consulted in the past 20 years (2000-2020) resulting in a total of 15 included studies. Across identified studies just one study provided prevention with 7 harm reduction and 7 early interventions. The quality of the literature was variable with just 8 randomised controlled trials with the remainder matched controls or longitudinal cohort studies. The target group was predominantly gamblers accessing betting and casino websites (n = 8). Studies administered four types of interventions which included personalised and normative feedback, limit setting, self-directed cognitive and behavioural therapy and self-exclusion. These were delivered via customer gaming accounts, email, and self-learning packages. The available literature shows promise in the effectiveness of internet delivered interventions. However, the limited number of studies included in this review highlight significant lost opportunities to leverage technology in the prevention and reduction of gambling harm.

A prognostic model, including quantitative fetal fibronectin, to predict preterm labour: the QUIDS meta-analysis and prospective cohort study.

The diagnosis of preterm labour is challenging. False-positive diagnoses are common and result in unnecessary, potentially harmful treatments (e.g. tocolytics, antenatal corticosteroids and magnesium sulphate) and costly hospital admissions. Measurement of fetal fibronectin in vaginal fluid is a biochemical test that can indicate impending preterm birth. To develop an externally validated prognostic model using quantitative fetal fibronectin concentration, in combination with clinical risk factors, for the prediction of spontaneous preterm birth and to assess its cost-effectiveness. The study comprised (1) a qualitative study to establish the decisional needs of pregnant women and their caregivers, (2) an individual participant data meta-analysis of existing studies to develop a prognostic model for spontaneous preterm birth within 7 days in women with symptoms of preterm labour based on quantitative fetal fibronectin and clinical risk factors, (3) external validation of the prognostic model in a prospective cohort study across 26 UK centres, (4) a model-based economic evaluation comparing the prognostic model with qualitative fetal fibronectin, and quantitative fetal fibronectin with cervical length measurement, in terms of cost per QALY gained and (5) a qualitative assessment of the acceptability of quantitative fetal fibronectin. The model was developed using data from five European prospective cohort studies of quantitative fetal fibronectin. The UK prospective cohort study was carried out across 26 UK centres. Pregnant women at 22+0-34+6 weeks' gestation with signs and symptoms of preterm labour. Quantitative fetal fibronectin. Spontaneous preterm birth within 7 days. The individual participant data meta-analysis included 1783 women and 139 events of spontaneous preterm birth within 7 days (event rate 7.8%). The prognostic model that was developed included quantitative fetal fibronectin, smoking, ethnicity, nulliparity and multiple pregnancy. The model was externally validated in a cohort of 2837 women, with 83 events of spontaneous preterm birth within 7 days (event rate 2.93%), an area under the curve of 0.89 (95% confidence interval 0.84 to 0.93), a calibration slope of 1.22 and a Nagelkerke R2 of 0.34. The economic analysis found that the prognostic model was cost-effective compared with using qualitative fetal fibronectin at a threshold for hospital admission and treatment of ≥ 2% risk of preterm birth within 7 days. The outcome proportion (spontaneous preterm birth within 7 days of test) was 2.9% in the validation study. This is in line with other studies, but having slightly fewer than 100 events is a limitation in model validation. A prognostic model that included quantitative fetal fibronectin and clinical risk factors showed excellent performance in the prediction of spontaneous preterm birth within 7 days of test, was cost-effective and can be used to inform a decision support tool to help guide management decisions for women with threatened preterm labour. The prognostic model will be embedded in electronic maternity records and a mobile telephone application, enabling ongoing data collection for further refinement and validation of the model. This study is registered as PROSPERO CRD42015027590 and Current Controlled Trials ISRCTN41598423. This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 25, No. 52.

Kikuchi necrotizing lymphadenopathy: a tip of the iceberg disease?

Kikuchi-Fujimoto disease (KFD) is a rare benign condition also called histiocytic necrotizing lymphadenitis, which typically presented as fever with cervical lymphadenopathy in previously healthy individual. We presented a case of 11 year old boy with fever and cervical lymphadenopathy since 2 months. Lymph node biopsy was performed which suggested of KFD and was treated symptomatically. KFD incidence is rare but clinicians should be alert if young patient comes with fever and cervical lymphadenopathy to lower the chance of unwanted laboratory test and harmful treatment.

Improving Timeliness of Antibiotic Administration Using a Provider and Pharmacist Facing Sepsis Early Warning System in the Emergency Department Setting: A Randomized Controlled Quality Improvement Initiative.

Results of pre-post intervention studies of sepsis early warning systems have been mixed, and randomized clinical trials showing efficacy in the emergency department setting are lacking. Additionally, early warning systems can be resource-intensive and may cause unintended consequences such as antibiotic or IV fluid overuse. We assessed the impact of a pharmacist and provider facing sepsis early warning systems on timeliness of antibiotic administration and sepsis-related clinical outcomes in our setting. A randomized, controlled quality improvement initiative. The main emergency department of an academic, safety-net healthcare system from August to December 2019. Adults presenting to the emergency department. Patients were randomized to standard sepsis care or standard care augmented by the display of a sepsis early warning system-triggered flag in the electronic health record combined with electronic health record-based emergency department pharmacist notification. The primary process measure was time to antibiotic administration from arrival. A total of 598 patients were included in the study over a 5-month period (285 in the intervention group and 313 in the standard care group). Time to antibiotic administration from emergency department arrival was shorter in the augmented care group than that in the standard care group (median, 2.3 hr [interquartile range, 1.4-4.7 hr] vs 3.0 hr [interquartile range, 1.6-5.5 hr]; p = 0.039). The hierarchical composite clinical outcome measure of days alive and out of hospital at 28 days was greater in the augmented care group than that in the standard care group (median, 24.1 vs 22.5 d; p = 0.011). Rates of fluid resuscitation and antibiotic utilization did not differ. In this single-center randomized quality improvement initiative, the display of an electronic health record-based sepsis early warning system-triggered flag combined with electronic health record-based pharmacist notification was associated with shorter time to antibiotic administration without an increase in undesirable or potentially harmful clinical interventions.

An Alert to Possible False Positives With a Commercial Assay for MET Exon 14 Skipping

IntroductionBecause molecular-targeted drugs against MET exon 14 (METex14) skipping have been approved, molecular testing of the alteration has added to clinical guidelines. There are several such assays, but methodological issues have been reported. MethodsMETex14 skipping results from three assays (Oncomine DxTT, ArcherMET, and laboratory-developed reverse-transcriptase polymerase chain reaction test [LDT RT-PCR]) were compared in a relatively small series of the specimens diagnosed as advanced NSCLC (n = 50). ResultsThe ArcherMET and LDT RT-PCR results were identical for all 50 samples, but eight samples had discordant results between Oncomine DxTT and the other two assays. All eight samples had METex14 skipping with Oncomine DxTT and wild-type signals with ArcherMET and LDT RT-PCR. The discordance might be caused by the homopolymeric error of the splice donor site with Oncomine DxTT, and false positives could be distinguished by relatively low read counts. ConclusionsAlthough the caution in detecting METex14 skipping focuses on false negatives in the literature, false positives were first noted at a relatively high frequency (8 of 26, 30.8%) in this study. According to the results of previous clinical trials using the other tyrosine kinase inhibitors, it could be surmised that MET inhibitor treatment in patients without METex14 skipping is detrimental. Clinicians need to be alert to the false positives that can lead to harmful treatments.

Race, ethnicity, and emergency department post-overdose care

BackgroundEmergency department (ED) visits for opioid-related overdoses continue to rise across the United States, particularly among Black, Latinx, and American Indian/Alaskan Native communities. A minority of people with opioid use disorder (OUD) engages in formal addiction treatment and there are racial disparities in treatment access. ED visits for opioid overdose are crucial opportunities to link individuals with OUD to harm reduction and treatment services. However, we know little about whether racial inequities exist in ED treatment after opioid overdose. MethodsThis observational, cross-sectional study examined differences in services provided to overdose patients who were discharged after an ED visit for opioid overdose by patient race-ethnicity. Primary outcomes included provision of take-home naloxone, ED-based behavioral counseling, and linkage to treatment. Race-ethnicity differences in post-overdose ED services were evaluated using chi-square analyses, and multivariable logistic regression analyses were conducted to examine associations of race-ethnicity with receiving post-overdose services, controlling for other institutional-, provider-, and patient-level factors. ResultsFrom September 2017 to February 2020, 734 patients were discharged from the ED for an opioid-related overdose. Most patients were White non-Latinx (70.0%), 8.9% were Black non-Latinx, 3.3% were Other race non-Latinx, and 18.0% were Latinx. Take-home naloxone was the most frequent intervention provided to patients while behavioral counseling was the lowest across all race-ethnicity categories. There were no statistically significant differences in provision of take-home naloxone and treatment referral based on patient race-ethnicity. However, a lower proportion of discharged Black non-Latinx patients received behavioral counseling compared to patients of other race-ethnicities, and the odds of receiving behavioral counseling was significantly higher for White non-Latinx (OR: 1.75; 95% CI: 1.00, 3.06); Latinx (OR: 2.06; 95% CI: 1.05, 4.06); and Other race non-Latinx (OR: 3.29; 95% CI: 1.18, 9.15) patients compared to Black non-Latinx patients. ConclusionBlack non-Latinx patients discharged from the ED for an opioid-related overdose were less likely to receive behavioral counseling compared to non-Black patients. Possible reasons for this decreased provision of behavioral counseling include provider bias, patient mistrust of the medical and behavioral health care systems, and limited provider training in addiction medicine and motivational interviewing. These inequities add to the known racial disparities in ED patient care. Further research should elucidate barriers to behavioral counseling within ED settings and factors contributing to racial inequities in post-overdose emergency care.

Modeling Hepatitis C Elimination Among People Who Inject Drugs in New Hampshire

The success of direct-acting antiviral therapies for chronic hepatitis C virus (HCV) infection led the World Health Organization to set elimination targets by 2030. For the United States to achieve these benchmarks, public health responses must target high-risk populations, such as people who inject drugs (PWID), a group with high rates of HCV incidence and low rates of treatment uptake. To evaluate potential improvements in the HCV care cascade among PWID, focusing on improved testing, treatment uptake, and access to harm reduction. This decision analytic model used a differential equation-based dynamic transmission model based on data from New Hampshire, an illustrative state with a large number of PWID and limited HCV treatment infrastructure. Surveillance data through 2020 was used for model parameterization, and the final analysis was conducted in May 2021. Model forecasts of chronic HCV cases and advanced-stage HCV outcomes from 2022 to 2045. A total of 6 scenarios were tested: (1) the base case, (2) improved harm reduction, (3) improved testing, (4) improved treatment, (5) improved testing and treatment, and (6) improved testing, treatment, and harm reduction. All scenarios with improved testing, treatment uptake, and/or access to harm reduction were associated with decreases in forecasted HCV prevalence and HCV-associated mortality compared with the base case. Improving harm reduction, testing, and treatment individually were forecast to reduce prevalence of HCV in 2045 from 69.7% in the base case to 62.8%, 45.7%, and 35.5%, respectively. Combining treatment and testing improvements was associated with a 2045 prevalence of 0.3%; adding harm reduction improvements was associated with further reductions in prevalence forecasts (to 0.2%), with fewer total treatments (10 960 vs 13 219 from 2022-2045). In this modeling study, no single intervention was projected to achieve World Health Organization HCV elimination targets. Scenarios with improvements in both testing and treatment were associated with a prevalence of less than 3% by 2030 and achieved elimination targets. Adding improvements in harm reduction was associated with faster reductions in prevalence and fewer treatments.

Species stereotypes as a result of unconscious research biases compromise conservation efficacy

Taxonomic and geographic biases in ecological research are widely recognised. In addition, information bias within a species can impact our understanding of their biology. This can lead to an underestimation of potential intra- or inter-population level variation and plasticity, and incomplete inferences about species response curves across environmental gradients. The consequences of these ‘species stereotypes’ are misestimation of the potential niche and narrow, potentially biased, views of habitat and diet preferences. For example, species may be characterised as ecologically static, or a habitat, diet, or prey ‘specialist’. Several factors can contribute to the formation of a ‘stereotype’, including a focus on extant populations, or a subset of them, that only partially represent the full historical distribution of a species, and an emphasis on species interactions derived from a small number of potential communities. Such species stereotypes are likely widespread and impact on many taxa. These misconceptions can have knock-on effects for conservation programmes and lead to ineffective or harmful conservation interventions such as actively managing species in marginal habitats, not identifying key threats and incorrect predictions of vulnerability to environmental change. Recognising biases is vital to addressing these potential problems and providing accurate information for conservation programmes. Biases can be identified by evaluating historical distributions, translocations within historical distributions, developing mechanistic distribution models and assessing traditional ecological knowledge. We suggest that explicit assessment of biases and potential stereotypes are included in red listing or species assessments, biodiversity action plans, and protected area network design and evaluation.

Opioid use disorder treatment disruptions during the early COVID-19 pandemic and other emergent disasters: a scoping review addressing dual public health emergencies

BackgroundDuring public health emergencies, people with opioid use disorder (PWOUD) may be particularly impacted. Emergent disasters such as the COVID-19 pandemic disrupt already-strained harm reduction efforts and treatment availability. This study aims to answer three research questions. How do public health emergencies impact PWOUD? How can health systems respond to novel public health emergencies to serve PWOUD? How can the results of this scoping review be contextualized to the province of Alberta to inform local stakeholder responses to the pandemic?MethodsWe conducted a scoping review using the 6-stage Arksey and O’Malley framework to analyse early-pandemic and pre-pandemic disaster literature. The results of the scoping review were contextualized to the local pandemic response, through a Nominal Group Technique (NGT) process with frontline providers and stakeholders in Alberta, Canada.ResultsSixty one scientific journal articles and 72 grey literature resources were included after full-text screening. Forty sources pertained to early COVID-19 responses, and 21 focused on OUD treatment during other disasters. PWOUD may be more impacted than the general population by common COVID-19 stressors including loss of income, isolation, lack of rewarding activities, housing instability, as well as fear and anxiety. They may also face unique challenges including threats to drug supplies, stigma, difficulty accessing clean substance use supplies, and closure of substance use treatment centres. All of these impacts put PWOUD at risk of negative outcomes including fatal overdose. Two NGT groups were held. One group (n = 7) represented voices from urban services, and the other (n = 4) Indigenous contexts. Stakeholders suggested that simultaneous attention to multiple crises, with adequate resources to allow attention to both social and health systems issues, can prepare a system to serve PWOUD during disasters.ConclusionThis scoping review and NGT study uncovers how disasters impact PWOUD and offers suggestions for better serving PWOUD.

HIV Risk Among Urban and Suburban People Who Inject Drugs: Elevated Risk Among Fentanyl and Cocaine Injectors in Maryland.

Drug overdose remains a leading cause of death in the US, with growing rates attributable to illicit fentanyl use. Recent HIV outbreaks among people who inject drugs (PWID) and service disruptions from COVID-19 have renewed concerns on HIV resurgence. We examined the relationship between fentanyl use and three injection-related HIV risk behaviors among PWID in Baltimore City (BC) and Anne Arundel Country (AAC), Maryland. PWID (N = 283) were recruited to the study through targeted sampling at street-based locations in BC and AAC from July 2018 to March 2020. Receptive syringe sharing (RSS) [adjusted odds ratio (AOR): 2.8, 95% confidence interval (CI): 1.2–6.3] and daily injecting (AOR: 1.9, 95% CI: 1.0–3.6) were associated with injecting fentanyl and cocaine together. Fentanyl availability and COVID-19 bring new HIV prevention challenges, particularly among those who inject fentanyl with cocaine, highlighting the importance to expand and sustain harm reduction, prevention, and treatment services for PWID to reduce HIV and overdose burden.

The very elderly followed at a nephrology center: metabolic acidosis as a predictor of progressive chronic kidney disease

Chronic kidney disease is an increasingly common diagnosis in the very elderly and identifying the patients who benefit from a nephrologist’s intervention and the ones who would not might avoid wasteful or harmful interventions. The aim of this study is to identify the risk factors for progressive versus non -progressive chronic kidney disease in a population aged over 80 years old. We performed a cohort single -center retrospective study including 101 patients over 80 years old with chronic kidney disease diagnosed for at least five years and followed regularly by a nephrologist. Progressive disease was defined as glomerular filtration rate declines greater than 5 mL/min/1.73 m2/year. Of the 101 patients, 33.7% had progressive chronic kidney disease. The median glomerular filtration progression rate was 3.0 [2.1 -6.0] mL/ min/1.73m2/year. Hypertension and diabetes mellitus prevalence was similar between groups. Nephrology follow -up time was longer in the progressive group (5.0 vs 2.0 years, p=0.01). Regarding chronic kidney disease complications, 37.6% had anemia and half of these needed erythropoiesis -stimulating agents. None of the patients had hyperphosphatemia. About 18.8% presented metabolic acidosis. In multivariable analysis, after adjusting for covariables such as age, hypertension, and diabetes mellitus only the presence of metabolic acidosis (OR 0.4, CI: 0.1 -0.8) was associated with the development of progressive chronic kidney disease. Progressive chronic kidney disease group presented higher mortality (log rank 4.5, p=0.03). Ischemic cardiomyopathy (OR: 0.5, CI: 0.2 -0.9) and progressive chronic kidney disease (OR: 0.6, CI:0.3 -0.8) were associated with all -cause mortality. Our results showed that most elderly patients have non -progressive chronic kidney disease. Patients with metabolic acidosis seem to be at an increased risk for developing progressive disease. Most elderly patients die before reaching end -stage kidney disease, so it is important to look at progressive kidney disease in those patients as an important marker of comorbidity and privilege cardioprotective measures.
