Revisiting TNM staging for EBV-related nasopharyngeal carcinoma

Advances in imaging and novel treatment approaches might have outpaced the prognostic capabilities of the current AJCC/UICC TNM 8th edition for staging nasopharyngeal carcinoma (NPC). In this issue of Cancer Cell, Du et al. propose a new TNM-9 classification that incorporates these updates.

A student-led educational activity on trauma informed care: Reflections and recommendations

OBJECTIVE

The prevalence of trauma exposure is remarkably high globally. In Canada, for example, it is estimated that over 75% of the national population have experienced a traumatic event during their lifetime. While exposure to trauma is linked with a number of poor health-related problems, the teaching of trauma informed care (TIC) principles across Canadian medical schools is uncertain, and many primary care providers (PCP) feel underprepared to have discussions regarding trauma with their patient. The purpose of this report is to promote the teaching and better knowledge of TIC among health professional learners.

METHOD

A team of medical and health sciences students at a Canadian university hosted a virtual, interdisciplinary and educational Trauma Informed Care Conference (TICC) that was targeted toward health care learners using an interactive panel of interdisciplinary experts.

RESULTS

A total of 107 participants attended the TICC. Select lectures were presented to improve participants' knowledge of TIC through a myriad of lenses, including historical, cultural, developmental/perinatal, intergenerational, and system-oriented sources. TIC was presented as promoting trauma awareness, trust, safety, collaboration, autonomy, and a strengths-based approach to care.

CONCLUSIONS

We advocate for better awareness of TIC, the associated trauma theories, and implementation of the core values and principles of TIC in the training of health professionals. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Results of a national survey of substance use treatment services for youth under community supervision

BACKGROUND

Despite the heightened risk for substance use (SU) among youth in the juvenile justice system, many do not receive the treatment that they need.

OBJECTIVES

The purpose of this study is to examine the extent to which youth under community supervision by juvenile justice agencies receive community-based SU services and the factors associated with access to such services.

METHODS

Data are from a nationally representative sample of Community Supervision (CS) agencies and their primary behavioral health (BH) partners. Surveys were completed by 192 CS and 271 BH agencies.

RESULTS

SU services are more often available through BH than CS for all treatment modalities. EBPs are more likely to be used by BH than by CS. Co-location of services occurs most often in communities with fewer treatment options and is associated with higher interagency collaboration. Youth are more likely to receive services in communities with higher EBP use, which mediates the relationship between the availability of SU treatment modalities and the proportion of youth served.

CONCLUSION

Findings identify opportunities to strengthen community systems and improve linkage to care.

Impact of implementation interventions to improve substance use service delivery on recidivism among justice-involved youth

Substance use disorders (SUD) are prevalent among justice-involved youth (JIY) and are a robust predictor of re-offending. Only a fraction of JIY with substance use problems receive treatment. This paper describes the impacts of system-level efforts to improve identification and referral to treatment on recidivism of JIY. A cluster randomized trial involving 20 county juvenile justice agency sites across 5 states was used to implement an organizational intervention (Core vs Enhanced) to juvenile justice staff and community-based treatment providers, working with 18,698 JIY from March 2014 to August 2017. Recidivism rates over four study time periods were examined. Logistic regression was used to predict recidivism as a function of site, need for SUD services, level of supervision, time, organizational intervention, and time x intervention interaction terms. Results indicated that Enhanced sites showed decreased levels of recidivism compared to Core-only sites, where it increased over time. Additionally, need for SU services, level of supervision, and site were significant predictors of reoffending. Findings suggest the potential value of facilitation of juvenile justice agency efforts to increasing identification of and referral to SUD services of JIY in need of such services for reducing further contact with the legal system.

Unified classification and risk-stratification in Acute Myeloid Leukemia

Clinical recommendations for Acute Myeloid Leukemia (AML) classification and risk-stratification remain heavily reliant on cytogenetic findings at diagnosis, which are present in <50% of patients. Using comprehensive molecular profiling data from 3,653 patients we characterize and validate 16 molecular classes describing 100% of AML patients. Each class represents diverse biological AML subgroups, and is associated with distinct clinical presentation, likelihood of response to induction chemotherapy, risk of relapse and death over time. Secondary AML-2, emerges as the second largest class (24%), associates with high-risk disease, poor prognosis irrespective of flow Minimal Residual Disease (MRD) negativity, and derives significant benefit from transplantation. Guided by class membership we derive a 3-tier risk-stratification score that re-stratifies 26% of patients as compared to standard of care. This results in a unified framework for disease classification and risk-stratification in AML that relies on information from cytogenetics and 32 genes. Last, we develop an open-access patient-tailored clinical decision support tool.

Bacillus Calmette-Guerin (BCG) induces superior anti-tumour responses by Vδ2+ T cells compared with the aminobisphosphonate drug zoledronic acid

Vδ2⁺ T cells can recognize malignantly transformed cells as well as those infected with mycobacteria. This cross-reactivity supports the idea of using mycobacteria to manipulate Vδ2⁺ T cells in cancer immunotherapy. To date, therapeutic interventions using Vδ2⁺ T cells in cancer have involved expanding these cells in or ex vivo using zoledronic acid (ZA). Here, we show that the mycobacterium Bacillus Calmette–Guérin (BCG) also causes Vδ2⁺ T-cell expansion in vitro and that resulting Vδ2⁺ cell populations are cytotoxic toward tumour cell lines. We show that both ZA and BCG-expanded Vδ2+ cells effectively killed both Daudi and THP-1 cells. THP-1 cell killing by both ZA and BCG-expanded Vδ2+ cells was enhanced by treatment of targets cells with ZA. Although no difference in cytotoxic activity between ZA- and BCG-expanded Vδ2+ cells was observed, BCG-expanded cells degranulated more and produced a more diverse range of cytokines upon tumour cell recognition compared to ZA-expanded cells. ZA-expanded Vδ2+ cells were shown to upregulate exhaustion marker CD57 to a greater extent than BCG-expanded Vδ2+ cells. Furthermore, ZA expansion was associated with upregulation of inhibitory markers PD-1 and TIM3 in a dose-dependent manner whereas PD-1 expression was not increased following expansion using BCG. Intradermal BCG vaccination of rhesus macaques caused in vivo expansion of Vδ2⁺ cells. In combination with the aforementioned in vitro data, this finding suggests that BCG treatment could induce expansion of Vδ2⁺ T cells with enhanced anti-tumour potential compared to ZA treatment and that either ZA or BCG could be used intratumourally as a means to potentiate stronger anti-tumour Vδ2⁺ T-cell responses.

Identifying individual and environmental predictors of opioid and psychostimulant use among adolescents and young adults following outpatient treatment

BACKGROUND

The United States (US) continues to grapple with a drug overdose crisis. While opioids remain the main driver of overdose deaths, deaths involving psychostimulants such as methamphetamine are increasing with and without opioid involvement. Recent treatment admission data reflect overdose fatality trends suggesting greater psychostimulant use, both alone and in combination with opioids. Adolescents and young adults are particularly vulnerable with generational trends showing that these populations have particularly high relapse rates following treatment.

METHODS

We assessed demographic, psychosocial, psychological comorbidity, and environmental factors (percent below the poverty line, percent unemployed, neighborhood homicide rate, population density) that confer risk for opioid and/or psychostimulant use following substance use disorder treatment using two complementary machine learning approaches-random forest and least absolute shrinkage and selection operator (LASSO) modelling-with latency to opioid and/or psychostimulant as the outcome variable.

RESULTS

Individual level predictors varied by substance use disorder severity, with age, tobacco use, criminal justice involvement, race/ethnicity, and mental health diagnoses emerging at top predictors. Environmental variabels including US region, neighborhood poverty, population, and homicide rate around patients' treatment facility emerged as either protective or risk factors for latency to opioid and/or psychostimulant use.

CONCLUSIONS

Environmental variables emerged as one of the top predictors of latency to use across all levels of substance use disorder severity. Results highlight the need for tailored treatments based on severity, and implicate environmental variables as important factors influencing treatment outcomes.

The impact of Juvenile Drug Treatment Courts (JDTC) implementing Federal Evidence-Based Guidelines on recidivism and substance use: multisite Randomized Controlled Trial (RCT) and Regression Discontinuity (RDD) Designs

BACKGROUND

Juvenile drug treatment courts (JDTC) have struggled to define themselves since their inception in 1995. Early courts followed a format similar to adult drug courts, but these did not address the unique needs of juveniles, which led to the creation of 16 Strategies by a consensus panel of practitioners and researchers. But, like the first JDTCs, research with courts following these strategies failed to provide convincing evidence that this "model" was associated with significant reductions in recidivism or drug use. More recently, a new set of evidence-based guidelines were developed through meta-analyses commissioned by the Office of Juvenile Justice and Delinquency Prevention (OJJDP, 2016).

METHOD

OJJDP provided funding for a rigorous multi-site evaluation of the guidelines. This study protocol paper for the Juvenile Drug Treatment Court (JDTC) Guidelines Cross-Site Evaluation presents research designs for the comparison of youth outcomes from 10 JDTCs compared with 10 Traditional Juvenile Courts (TJCs) in the same jurisdictions. Two sites opted into a randomized controlled trial (RCT) and eight sites chose to follow a regression discontinuity design (RDD). Youth data are captured at baseline, and at 6- and 12-month follow-ups using an interview comprised of several standardized assessments. The youths' official records also are abstracted for recidivism and substance use information. The degree to which the evidence-based guidelines are implemented at each site is assessed via an in-depth court self-assessment collected at baseline and again 2 years later and via structured site visits conducted once during implementation.

DISCUSSION

As a field-based trial, using both RCT and RDD designs, findings will provide important, policy-relevant information regarding the implementation of the OJJDP evidence-based guidelines, including the degree to which JDTCs adopted and/or modified these practices, their relative impact on recidivism and substance use, as well as the degree to which JDTCs differ from TJCs. Specific inferences may be drawn about whether following or not following specific guidelines differentially impact youth outcomes, yielding recommendations about the translation of this information from research-to-practice for potentiating the broader adoption of these guidelines by JDTCs nationwide.

CLINICAL TRIALS REGISTRATION

This was not an NIH supported trial. The funder, OJJDP/NIJ, instead required publishing the design with even more information at https://www.ojp.gov/ncjrs/virtual-library/abstracts/juvenile-drug-treatment-court-jdtc-guidelines-cross-site-evaluation .

Understanding suicide clusters through exploring self-harm: Semi-structured interviews with individuals presenting with near-fatal self-harm during a suicide cluster

There was a highly publicised cluster of at least ten suicides in South Wales, United Kingdom, in 2007-2008. We carried out a qualitative descriptive study using cross-case thematic analysis to investigate the experiences and narratives of eight individuals who lived in the area where the cluster occurred and who survived an episode of near-fatal self-harm at the time of the cluster. Interviews were conducted from 01.01.2015 to 31.12.2015. All interviewees denied that the other deaths in the area had affected their own suicidal behaviour. However, in other sections of the interviews they spoke about the cluster contributing to difficulties they were experiencing at the time, including damage to social relationships, feelings of loss and being out of control. When asked about support, the interviewees emphasized the importance of counselling, which they would have found helpful but in most cases did not receive, even in the case of close contacts of individuals who had died. The findings suggest that effective prevention messaging must be subtle, since those affected may not be explicitly aware of or acknowledge the imitative aspects of their behaviour. This could be related to stigma attached to suicidal behaviour in a cluster context. Lessons for prevention include changing the message from asking if people 'have been affected by' the suicide deaths to emphasising the preventability of suicide, and directly reaching out to individuals rather than relying on people to come forward.

Surgical Management of Idiopathic Partial Thrombosis of the Corpus Cavernosum

A 36-year-old African American man presented to the emergency department with 2 days of left-sided perineal pain after sexual activity. He was found to have induration in the left perineum overlying the proximal left corporal body. Clinical picture was suspicious for traumatic corporal rupture; however, advanced imaging showed a proximal segmental thrombosis of the left corpus cavernosum. The patient underwent perineal exploration with evacuation of an intracorporal penile hematoma. In spite of disrupting a fibrous membrane in the proximal corpora and drainage of the corpora, we observed repeat tumescence during the procedure because of an observed arterial high-flow state in the corpora cavernosum. This was resolved with administration of phenylephrine into the cavernosum. The patient had return of normal erectile function 2 days after the procedure with resolution of pain at the site.

Artificial Intelligence for Histology-Based Detection of Microsatellite Instability and Prediction of Response to Immunotherapy in Colorectal Cancer

Microsatellite instability (MSI) is a molecular marker of deficient DNA mismatch repair (dMMR) that is found in approximately 15% of colorectal cancer (CRC) patients. Testing all CRC patients for MSI/dMMR is recommended as screening for Lynch Syndrome and, more recently, to determine eligibility for immune checkpoint inhibitors in advanced disease. However, universal testing for MSI/dMMR has not been uniformly implemented because of cost and resource limitations. Artificial intelligence has been used to predict MSI/dMMR directly from hematoxylin and eosin (H&E) stained tissue slides. We review the emerging data regarding the utility of machine learning for MSI classification, focusing on CRC. We also provide the clinician with an introduction to image analysis with machine learning and convolutional neural networks. Machine learning can predict MSI/dMMR with high accuracy in high quality, curated datasets. Accuracy can be significantly decreased when applied to cohorts with different ethnic and/or clinical characteristics, or different tissue preparation protocols. Research is ongoing to determine the optimal machine learning methods for predicting MSI, which will need to be compared to current clinical practices, including next-generation sequencing. Predicting response to immunotherapy remains an unmet need.

Identifying Actionable Causes of Potentially Avoidable Readmissions to an Oncology Service at a Safety Net Hospital

PURPOSE

Hospital readmissions occur commonly in those receiving cancer care and result in impaired quality of life and increased costs. Causes of readmission in safety net hospitals that serve vulnerable populations are not well understood. The primary goal of this project was to identify potentially avoidable and intervenable causes of readmissions to an urban safety net hospital.

METHODS

A retrospective chart review was performed on patients who were readmitted within 30 days of discharge from the hematology and oncology service at Boston Medical Center over the 6-month period between October 2018 and March 2019. Charts were reviewed by three internal medicine residents and discussed under the supervision of an attending oncologist.

RESULTS

Two hundred ninety-one patient encounters involving 203 unique patients were identified in the 6-month study period. Of these 291 encounters, 80 encounters (27.5%) were followed by a readmission within 30 days and occurred in 61 (30.0%) unique patients. Nineteen (31.1%) of these 61 patients experienced two readmissions within 30 days of discharge. Twenty-five readmissions (31.3%) were classified as potentially avoidable, with the most common cause of potentially avoidable readmissions attributed to ascitic or pleural fluid reaccumulation (8, 32%). The majority of presumed nonpreventable readmissions were due to expected complications of cancer progression and treatment-related side effects.

DISCUSSION

In conclusion, readmissions were common, and a modifiable reason for 30-day readmissions was identified. Addressing recurrent ascitic and pleural fluid reaccumulation in the outpatient setting could help to reduce inpatient hospital readmission on an inpatient oncology service.

Contacts with primary and secondary healthcare prior to suicide: case-control whole-population-based study using person-level linked routine data in Wales, UK, 2000-2017

BACKGROUND

Longitudinal studies of patterns of healthcare contacts in those who die by suicide to identify those at risk are scarce.

AIMS

To examine type and timing of healthcare contacts in those who die by suicide.

METHOD

A population-based electronic case-control study of all who died by suicide in Wales, 2001-2017, linking individuals' electronic healthcare records from general practices, emergency departments and hospitals. We used conditional logistic regression to calculate odds ratios, adjusted for deprivation. We performed a retrospective continuous longitudinal analysis comparing cases' and controls' contacts with health services.

RESULTS

We matched 5130 cases with 25 650 controls (5 per case). A representative cohort of 1721 cases (8605 controls) were eligible for the fully linked analysis. In the week before their death, 31.4% of cases and 15.6% of controls contacted health services. The last point of contact was most commonly associated with mental health and most often occurred in general practices. In the month before their death, 16.6 and 13.0% of cases had an emergency department contact and a hospital admission respectively, compared with 5.5 and 4.2% of controls. At any week in the year before their death, cases were more likely to contact healthcare services than controls. Self-harm, mental health and substance misuse contacts were strongly linked with suicide risk, more so when they occurred in emergency departments or as emergency admissions.

CONCLUSIONS

Help-seeking occurs in those at risk of suicide and escalates in the weeks before their death. There is an opportunity to identify and intervene through these contacts.

Means restriction for the prevention of suicide on roads

BACKGROUND

Road traffic suicides are common. However, due to the difficulty in distinguishing between motor vehicle crash fatalities and actual suicides, no official figures exist for this method of suicide. Restricting access to means is an important universal or population-based approach to suicide prevention with clear evidence of its effectiveness. However, the evidence with respect to means restriction for the prevention of suicide on roads is not well established. We conducted a systematic review to assess the impact of restrictions on the availability of, or access to, means of suicide on roads.

OBJECTIVES

To evaluate the effectiveness of interventions to restrict the availability of, or access to, means of suicide on roads.

SEARCH METHODS

We searched the Cochrane Library, MEDLINE, Embase, PsycINFO, and the Transport Research International Documentation (TRID) Database from the date of database inception to March 2020. We conducted searches of the World Health Organization International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov to identify unpublished and ongoing studies. We applied no date, language, or publication status restrictions to these searches.

SELECTION CRITERIA

Eligible studies were randomised or quasi-randomised controlled trials, controlled intervention studies without randomisation, before-after studies, or studies using interrupted time series designs, which evaluated interventions to restrict the availability of, or access to, means of suicide on roads.

DATA COLLECTION AND ANALYSIS

Two review authors screened abstracts and full-text publications against the inclusion criteria. Two review authors planned to independently extract data and assess risk of bias of included studies. However, we identified no studies eligible for inclusion.

MAIN RESULTS

We identified no studies that met the inclusion criteria for this review.

AUTHORS' CONCLUSIONS

This systematic review highlights the paucity of research around road traffic suicides and the need for future robust studies that aim to investigate the effectiveness of interventions to prevent suicide on roads. Suicide ascertainment is a key issue; therefore, clear objective criteria are necessary in order to scale up and study this method more accurately. In the absence of any substantial evidence, we advocate for more awareness on road traffic suicides and its inclusion in future government suicide prevention policies. Further research exploring effective measures, particularly those that do not require driver compliance, are also needed.

Urban green infrastructure size, quality and proximity and health outcomes in older populations

Background

A city's multi-functional network of green and blue spaces has an important role underpinning the health and wellbeing of its residents. Although evidence of positive links between nature and health is plentiful, little is known about which particular aspects of green and blue spaces are most influential, and how benefits might vary between social groups and age.

Methods

We used a green infrastructure (GI) approach combining a high-resolution spatial dataset of land-cover and function with area-level demographic and socio-economic data. A comprehensive characterisation of the Greater Manchester UK city region was generated. The GI attributes were used in step-wise multi-level regression analyses to test for associations between population chronic morbidity and the functional, physical and spatial components of GI across an urban socio-demographic gradient.

Results

Individual GI attributes were significantly associated with health in all socio-demographic contexts; even when associations between health and overall green cover were non-significant. For areas with having higher proportions of older people ('older neighbourhoods'), associations were found between health and land-cover diversity, informal greenery and patch size in high income areas. In lower income areas, health was predicted by proximity to public parks and recreation land.

Conclusions

A nuanced description of greenspace in terms of quality, cover type, diversity explains more variation in population health than a single metric such as percentage green cover. People in urban neighbourhoods that have older age populations and lower income are disproportionately healthy if their neighbourhoods contain accessible, good quality public greenspace. This has implications for strategies to decrease health inequalities and inform international initiatives, such as the World Health Organisation's Age-Friendly Cities programme.

Key messages

A nuanced description of green and blue space in terms of quality, cover type, diversity explains more variation in population health than a single metric such as percentage green cover. People in urban neighbourhoods that have older age populations and lower income are disproportionately healthy if their neighbourhoods contain accessible, good quality public greenspace.

Recidivism Among Justice-Involved Youth: Findings From JJ-TRIALS

Recidivism, and the factors related to it, remains a highly significant concern among juvenile justice researchers, practitioners, and policy makers. Recent studies highlight the need to examine multiple measures of recidivism as well as conduct multilevel analyses of this phenomenon. Using data collected in a National Institute on Drug Abuse (NIDA)-funded Juvenile Justice-Translational Research on Interventions for Adolescents in the Legal System (JJ-TRIALS) cooperative agreement, we examined individual- and site-level factors related to 1-year recidivism among probation youth in 20 sites in five states to answer research questions related to how recidivism rates differ across sites and the relationships between individual-level variables and a county-level concentrated disadvantage measure and recidivism. Our findings of large site differences in recidivism rates, and complex relationships between individual and county-level predictors of recidivism, highlight the need for more nuanced, contextually informed, multilevel approaches in studying recidivism among juveniles.

A Content Analysis and Comparison of Two Peaks of Newspaper Reporting During a Suicide Cluster to Examine Implications for Imitation, Suggestion, and Prevention

Abstract. Background: During 2007–2008, media attention focused on a cluster of youth suicides in the UK. There were two peaks (P1, P2) in the volume of newspaper reporting of the deaths. The number of possible suicides was greater than expected at the time of the first peak but not at the time of the second. Aims: To explore any differences in the content of the reporting peaks and to consider implications for imitation and prevention. Method: A content analysis of two peaks of newspaper reporting was conducted. Results: There were 204 articles in P1 (December 27, 2007 to February 19, 2008) and 157 in P2 (February 20, 2008 to March 15, 2008). Four main themes were identified: individual stories; possible causes; features of reporting of the cluster; and educating and informing the public. P1 articles more frequently contained: explicit details of method; photographs of the deceased, and contained more characterization of individuals. Limitations: The focus was on print media, future studies should incorporate online and social media content. Conclusion: The findings provide some support for the hypothesis of a process of suggestion initiated by sensationalist reporting in P1. This contributes to the evidence base of the role of the press in suicide imitation and prevention, highlighting the importance of care when reporting suicides.

The considerations, experiences and support needs of family members making treatment decisions for patients admitted with major stroke: a qualitative study

Background

Treatment decision-making by family members on behalf of patients with major stroke can be challenging because of the shock of the diagnosis and lack of knowledge of the patient’s treatment preferences. We aimed to understand how, and why, family members made certain treatment decisions, and explored their information and support needs.

Method

Semi-structured interviews with family members (n = 24) of patients with major stroke, within 2 weeks of hospital admission. Data were analysed thematically.

Results

Families’ approach to treatment decision-making lay on a spectrum according to the patient’s state of health pre-stroke (i.e. patient’s prior experience of illness and functional status) and any views expressed about treatment preferences in the event of life-threatening illness. Support and information needs varied according to where they were on this spectrum. At one extreme, family members described deciding not to initiate life-extending treatments from the outset because of the patients’ deteriorating health and preferences expressed pre-stroke. Information from doctors about poor prognosis was merely used to confirm this decision. In the middle of the spectrum were family members of patients who had been moderately independent pre-stroke. They described the initial shock of the diagnosis and how they had initially wanted all treatments to continue. However, once they overcame their shock, and had gathered relevant information, including information about poor prognosis from doctors, they decided that life-extending treatments were no longer appropriate. Many reported this process to be upsetting and expressed a need for psychological support. At the other end of the spectrum were family members of previously independent patients whose preferences pre-stroke had not been known. Family members described feeling extremely distressed at such an unexpected situation and wanting all treatments to continue. They described needing psychological support and hope that the patient would survive.

Conclusion

The knowledge that family members’ treatment decision-making approaches lay on a spectrum depending on the patient’s state of health and stated preferences pre-stroke may allow doctors to better prepare for discussions regarding the patient’s prognosis. This may enable doctors to provide information and support that is tailored towards family members’ needs.

A Scoping Review of Barriers and Facilitators to Implementation of Medications for Treatment of Opioid Use Disorder within the Criminal Justice System

BACKGROUND

Policies aimed at addressing the high rates of opioid overdose have prioritized increasing access to medications for treatment of opioid use disorder (MOUD). Numerous barriers exist to providing MOUD within the criminal justice system and/or to justice-involved populations. The aim of this study was to conduct a scoping review of the peer-reviewed literature on implementation of MOUD within criminal justice settings and with justice-involved populations.

METHODS

A systematic search process identified 53 papers that addressed issues pertaining to implementation barriers or facilitators of MOUD within correctional settings or with justice-involved populations; these were coded and qualitatively analyzed for common themes.

RESULTS

Over half of the papers were published outside of the U.S. (n = 28); the most common study designs were surveys or structured interviews (n = 20) and qualitative interviews/focus groups (n = 18) conducted with correctional or treatment staff and with incarcerated individuals. Four categories of barriers and facilitators were identified: institutional, programmatic, attitudinal, and systemic. Institutional barriers typically limited capacity to provide MOUD to justice-involved individuals, which led to programmatic practices in which MOUD was not implemented following clinical guidelines, often resulting in forcible withdrawal or inadequate treatment. These programmatic practices commonly led to aversive experiences among justice-involved individuals, who consequently espoused negative attitudes about MOUD and were reluctant to seek treatment with MOUD following their release to the community. Facilitators of MOUD implementation included increased knowledge and information from training interventions and favorable prior experiences with individuals being treated with MOUD among correctional and treatment staff. Few systemic facilitators to implementing MOUD with justice-involved individuals were evident in the literature.

CONCLUSION

Barriers to implementing MOUD in criminal justice settings and/or with justice-involved populations are pervasive, multi-leveled, and inter-dependent. More work is needed on facilitators of MOUD implementation.

Risk Factors for Development of Hypocalcemia in Patients With Cancer Treated With Bone-Modifying Agents

BACKGROUND

This retrospective analysis describes the prevalence of and risk factors associated with the development of hypocalcemia in patients with cancer receiving bone-modifying agents (BMAs) as supportive care.

PATIENTS AND METHODS

Patients with cancer treated with an intravenous or subcutaneous BMA, including pamidronate, zoledronic acid, or denosumab, at a tertiary care/safety net hospital in 2005 through 2015 were included in this retrospective review. We reviewed the medical records for predictive clinical and laboratory parameters and for patient outcomes.

RESULTS

A total of 835 patients with cancer received at least one dose of a BMA during the specified time frame; 205 patients (25%) developed hypocalcemia of CTCAE grade ≥1 within 8 weeks of BMA initiation, 18 of whom (8.8%) had grade ≥3, and 3 patients died as a result. Multivariate analysis showed that patients with hematologic malignancy (odds ratio [OR], 1.956; P=.025), bone metastases (OR, 2.443; P=.017), inpatient status (OR, 2.592; P<.001), and deficient baseline vitamin D levels (OR, 2.546; P<.023) were more likely to develop hypocalcemia. Hypercalcemia before BMA administration (OR, 0.474; P=.032) was protective.

CONCLUSIONS

Certain patient populations, including those with hematologic malignancies and/or bone metastases, warrant closer monitoring of calcium levels while receiving BMAs because of the high rate of hypocalcemia. Low pretreatment vitamin D levels are associated with the development of hypocalcemia. These data support close monitoring of calcium levels in patients with cancer receiving BMAs, in addition to adequate repletion of vitamin D before initiation of BMAs when possible.

Hierarchically Porous Silk/Activated-Carbon Composite Fibres for Adsorption and Repellence of Volatile Organic Compounds

Fabrics comprised of porous fibres could provide effective passive protection against chemical and biological (CB) threats whilst maintaining high air permeability (breathability). Here, we fabricate hierarchically porous fibres consisting of regenerated silk fibroin (RSF) and activated-carbon (AC) prepared through two fibre spinning techniques in combination with ice-templating-namely cryogenic solution blow spinning (Cryo-SBS) and cryogenic wet-spinning (Cryo-WS). The Cryo-WS RSF fibres had exceptionally small macropores (as low as 0.1 µm) and high specific surface areas (SSAs) of up to 79 m2·g-1. The incorporation of AC could further increase the SSA to 210 m2·g-1 (25 wt.% loading) whilst also increasing adsorption capacity for volatile organic compounds (VOCs).

Means restriction for the prevention of suicide by jumping

BACKGROUND

Jumping from a height is an uncommon but lethal means of suicide. Restricting access to means is an important universal or population-based approach to suicide prevention with clear evidence of its effectiveness. However, the evidence with respect to means restriction for the prevention of suicide by jumping is not well established.

OBJECTIVES

To evaluate the effectiveness of interventions to restrict the availability of, or access to, means of suicide by jumping. These include the use of physical barriers, fencing or safety nets at frequently-used jumping sites, or restriction of access to these sites, such as by way of road closures.

SEARCH METHODS

We searched the Cochrane Library, Embase, MEDLINE, PsycINFO, and Web of Science to May 2019. We conducted additional searches of the international trial registries including the World Health Organization International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov, to identify relevant unpublished and ongoing studies. We searched the reference lists of all included studies and relevant systematic reviews to identify additional studies and contacted authors and subject experts for information on unpublished or ongoing studies. We applied no restrictions on date, language or publication status to the searches. Two review authors independently assessed all citations from the searches and identified relevant titles and abstracts. Our main outcomes of interest were suicide, attempted suicide or self-harm, and cost-effectiveness of interventions.

SELECTION CRITERIA

Eligible studies were randomised or quasi-randomised controlled trials, controlled intervention studies without randomisation, before-and-after studies, or studies using interrupted time series designs, which evaluated interventions to restrict the availability of, or access to, means of suicide by jumping.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies for inclusion and three review authors extracted study data. We pooled studies that evaluated similar interventions and outcomes using a random-effects meta-analysis, and we synthesised data from other studies in a narrative summary. We summarised the quality of the evidence included in this review using the GRADE approach.

MAIN RESULTS

We included 14 studies in this review. Thirteen were before-and-after studies and one was a cost-effectiveness analysis. Three studies each took place in Switzerland and the USA, while two studies each were from the UK, Canada, New Zealand, and Australia respectively. The majority of studies (10/14) assessed jumping means restriction interventions delivered in isolation, half of which were at bridges. Due to the observational nature of included studies, none compared comparator interventions or control conditions. During the pre- and postintervention period among the 13 before-and-after studies, a total of 742.3 suicides (5.5 suicides per year) occurred during the pre-intervention period (134.5 study years), while 70.6 suicides (0.8 suicides per year) occurred during the postintervention period (92.4 study years) - a 91% reduction in suicides. A meta-analysis of all studies assessing jumping means restriction interventions (delivered in isolation or in combination with other interventions) showed a directionality of effect in favour of the interventions, as evidenced by a reduction in the number of suicides at intervention sites (12 studies; incidence rate ratio (IRR) = 0.09, 95% confidence interval (CI) 0.03 to 0.27; P < 0.001; I² = 88.40%). Similar findings were demonstrated for studies assessing jumping means restriction interventions delivered in isolation (9 studies; IRR = 0.05, 95% CI 0.01 to 0.16; P < 0.001; I² = 73.67%), studies assessing jumping means restriction interventions delivered in combination with other interventions (3 studies; IRR = 0.54, 95% CI 0.31 to 0.93; P = 0.03; I² = 40.8%), studies assessing the effectiveness of physical barriers (7 studies; IRR = 0.07, 95% CI 0.02 to 0.24; P < 0.001; I² = 84.07%), and studies assessing the effectiveness of safety nets (2 studies; IRR = 0.09, 95% CI 0.01 to 1.30; P = 0.07; I² = 29.3%). Data on suicide attempts were limited and none of the studies used self-harm as an outcome. There was considerable heterogeneity between studies for the primary outcome (suicide) in the majority of the analyses except those relating to jumping means restriction delivered in combination with other interventions, and safety nets. Nevertheless, every study included in the forest plots showed the same directional effects in favour of jumping means restriction. Due to methodological limitations of the included studies, we rated the quality of the evidence from these studies as low. A cost-effectiveness analysis suggested that the construction of a physical barrier on a bridge would be a highly cost-effective project in the long term as a result of overall reduced suicide mortality.

AUTHORS' CONCLUSIONS

The findings from this review suggest that jumping means restriction interventions are capable of reducing the frequency of suicides by jumping. However, due to methodological limitations of included studies, this finding is based on low-quality evidence. Therefore, further well-designed high-quality studies are required to further evaluate the effectiveness of these interventions, as well as other measures at jumping sites. In addition, further research is required to investigate the potential for suicide method substitution and displacement effects in populations exposed to interventions to prevent suicide by jumping.

One Health Education for Future Physicians: A Case Report of Cat-Transmitted Sporotrichosis

A healthy 35-year-old Brazilian woman presented with persistent redness, swelling, and multiple wounds on the hand 2 weeks after a cat bite in her home country. She was treated twice with amoxicillin-clavulanate but failed to demonstrate improvement. She then presented to our institution with a newly developed abscess on the right hand. Incision and drainage were performed and she was admitted to the hospital. She was subsequently treated with broad-spectrum antibiotics. Her symptoms improved but did not resolve. Four days after hospital discharge, a wound culture resulted as positive for Sporothrix schenchii. The patient was treated with itraconazole. Sporotrichosis is endemic in many countries including Brazil and is known to be transmitted by cat bites. Sporotrichosis should be considered in the differential diagnosis for patients who have symptoms of cellulitis after cat bites in an endemic area.

Overcoming barriers to resident scholarly productivity and research at a large academic institution

This article was migrated. The article was marked as recommended. Background: Scholarship is an important component of resident education that can increase future opportunities in academic medicine. Each year the Accreditation Council for Graduate Medical Education surveys internal medicine (IM) residents for their satisfaction with scholarship opportunities. The IM residents at our large academic center have consistently reported scores that were lower than expected. We designed this study to identify barriers to resident scholarship and successful interventions. Objective: Identify barriers to resident scholarly productivity and report the results of several interventions aimed at improving resident scholarship. Methods: Leaders within the IM residency program were interviewed with a standardized questionnaire, and an online survey was distributed to IM residents. Comparisons were made between program leader interviews and resident survey responses. Results: Program leaders unanimously agreed there are abundant research opportunities, that resident research is prioritized, and that time is the major research barrier. Conversely, only 72% of residents reported satisfaction with research opportunities, 56% felt that the program prioritized research, and finding a mentor was the most frequently reported research barrier (60%). Residents considered early discussions about research the most successful intervention to improve scholarship. Conclusion: Finding a mentor was the most important barrier to resident scholarship and discussing research early in the intern year was the most successful intervention.

National Survey of Juvenile Community Supervision Agency Practices and Caregiver Involvement in Behavioral Health Treatment

OBJECTIVES

This study sought to expand the sparse literature examining the extent to which family engagement interventions and the structural characteristics of juvenile community supervision agencies influence caregiver participation in youths' behavioral health (i.e., mental health and substance use) treatment.

METHODS

We analyzed data from a national survey of juvenile community supervision agencies, conducted as a part of a Juvenile Justice Translational Research on Interventions for Adolescents in the Legal System (JJTRIALS) Cooperative Agreement funded by NIH/NIDA.

RESULTS

Findings indicated agencies employ a variety of family engagement strategies, with passive strategies like services referrals and flexible schedules being more common than active strategies like provision of family therapy. Multivariate prediction of caregiver involvement in behavioral health care showed the most consistent effects for rural-urban location of the agency; rural agencies more successfully engaged families in their youth's behavioral healthcare. Relatedly, the more family engagement services, the greater the involvement of families in behavioral health treatment. Agencies with a juvenile drug treatment court also showed greater involvement.

CONCLUSIONS

Our findings that juvenile justice agencies are using multiple techniques to engage families, and that there is a relationship between use of these techniques and actual family engagement, would benefit from replication over time and in other jurisdictions. Analysis of data from a second wave of the national survey, recently completed, is expected to test the reliability of our findings over time, as well as identify whether and what kind of changes occurred in the two years following the first survey.

The Crohn's-Like Lymphoid Reaction to Colorectal Cancer-Tertiary Lymphoid Structures With Immunologic and Potentially Therapeutic Relevance in Colorectal Cancer

The Crohn's-like lymphoid reaction (CLR) to colorectal cancer (CRC), a CRC-specific ectopic lymphoid reaction, is thought to play an important role in the host response to CRC. CLR is characterized by peritumoral lymphocytic aggregates that are found at the advancing edge of the tumor. Spatial and molecular characterization of CLR within the tumor microenvironment (TME) have uncovered a spectrum of peritumoral lymphoid aggregates with varying levels of organization and maturation. In early stages of CLR development, CD4+ T-cells cluster predominantly with mature antigen presenting dendritic cells. As CLR matures, increasing numbers of B-cells, as well as follicular dendritic cells are recruited to create lymphoid follicles. When highly organized, CLR resembles functional tertiary lymphoid structures (TLS), allowing for lymphocyte recruitment to the TME and promoting a tumor-specific adaptive immune response. CLR has been consistently associated with favorable prognostic factors and improved survival among CRC patients, often providing more prognostic information than current clinical staging systems. However, consensus is lacking regarding CLR scoring and it is not clinically assessed or reported. Differences between CLR and other cancer-associated lymphoid structures exist both in primary and metastatic disease, underscoring the need to characterize organ-specific TLS. Further research is needed to explore the role of CLR in predicting response to immunotherapy and to leverage CLR to promote immunotherapeutic strategies in CRC.

Retrieval of critically ill adults using extracorporeal membrane oxygenation: the nine-year experience in New South Wales

In New South Wales, a coordinated extracorporeal membrane oxygenation (ECMO) retrieval program has been in operation since 2007. This study describes the characteristics and outcomes of patients transported by this service. We performed a retrospective observational study and included patients who were transported on ECMO to either of two adult tertiary referral hospitals in Sydney, New South Wales, between February 28, 2007 and February 29, 2016. One hundred and sixty-four ECMO-facilitated transports occurred, involving 160 patients. Of these, 118 patients (74%) were treated with veno-venous (VV) ECMO and 42 patients (26%) were treated with veno-arterial ECMO. The mean (standard deviation, SD) age was 40.4 (15.0) years. Seventy-seven transports (47%) occurred within metropolitan Sydney, 52 (32%) were from rural or regional areas within NSW, 17 (10%) were interstate transfers and 18 (11%) were international transfers. Transfers were by road (58%), fixed wing aircraft (27%) or helicopter (15%). No deaths occurred during transport. The median (interquartile range) duration of ECMO treatment was 8.9 (5.2-15.3) days. One hundred and nineteen patients (74%) were successfully weaned from ECMO and 109 (68%) survived to hospital discharge or transfer. In patients treated with VV ECMO, age, sequential organ failure assessment score, pre-existing immunosuppressive disease, pre-existing diabetes, renal failure requiring dialysis and failed prone positioning prior to ECMO were independently associated with increased mortality. ECMO-facilitated patient transport is feasible, safe, and results in acceptable short-term outcomes. The NSW ECMO Retrieval Service provides specialised support to patients with severe respiratory and cardiovascular illness, who may otherwise be too unstable to undergo inter-hospital transfer to access advanced cardiovascular and critical care services.
