RESUMO

PURPOSE: The use of tumor-informed circulating tumor DNA (ctDNA) testing in early-stage patients before surgery is limited mainly due to restricted tissue access and extended turnaround times. This study aimed to evaluate the clinical value of a tumor-naïve, methylation-based cell-free DNA assay in a large cohort of patients with resected non-small cell lung cancer (NSCLC). METHOD: We analyzed pre-surgical plasma samples from 895 patients with EGFR and ALK-wild-type, clinical stage I or II NSCLC. The ctDNA status was evaluated for its prognostic significance in relation to tumor volume, metabolic activity, histology, histological subtypes, and clinical-to-pathological TNM upstaging. RESULTS: Pre-surgical ctDNA detection was observed in 55 out of 414 (13%) patients with clinical stage I lung adenocarcinoma (LUAD) and was associated with poor recurrence-free survival (RFS) (2-year RFS 69% versus 91%; log-rank P<0.001), approaching that of clinical stage II LUAD. Pre-surgical ctDNA detection was not prognostic in patients with clinical stage II LUAD or non-LUAD. Within LUAD, tumor volume and positron emission tomography avidity interacted to predict pre-surgical ctDNA detection. Moreover, pre-surgical ctDNA detection was predictive of the post-surgical discovery of IASLC G3 tumors (P<0.001) and pathological TNM upstaging (P<0.001). Notably, pre-surgical ctDNA detection strongly correlated with higher PD-L1 expression in tumors (positive rates 28% vs. 55%, P<0.001), identifying a subgroup likely to benefit from anti-PD-(L)-1 therapies. CONCLUSION: These findings support the integration of ctDNA testing into routine diagnostic workflows in early-stage NSCLC without the need of tumor tissue profiling. Furthermore, it is clinically useful in identifying high-risk patients who might benefit from innovative treatments, including neoadjuvant immune checkpoint inhibitors.

RESUMO

BACKGROUND AND OBJECTIVE: Studies conflict about whether language discordance increases rates of hospital readmissions or emergency department (ED) revisits for adult and paediatric patients. The literature was systematically reviewed to investigate the association between language discordance and hospital readmission and ED revisit rates. DATA SOURCES: Searches were performed in PubMed, Embase and Google Scholar on 21 January 2021, and updated on 27 October 2022. No date or language limits were used. STUDY SELECTION: Articles that (1) were peer-reviewed publications; (2) contained data about patient or parental language skills and (3) included either unplanned hospital readmission or ED revisit as one of the outcomes, were screened for inclusion. Articles were excluded if: unavailable in English; contained no primary data or inaccessible in a full-text form (eg, abstract only). DATA EXTRACTION AND SYNTHESIS: Two reviewers independently extracted data using Preferred Reporting Items for Systematic Reviews and Meta-Analyses-extension for scoping reviews guidelines. We used the Newcastle-Ottawa Scale to assess data quality. Data were pooled using DerSimonian and Laird random-effects models. We performed a meta-analysis of 18 adult studies for 28-day or 30-day hospital readmission; 7 adult studies of 30-day ED revisits and 5 paediatric studies of 72-hour or 7-day ED revisits. We also conducted a stratified analysis by whether access to interpretation services was verified/provided for the adult readmission analysis. MAIN OUTCOMES AND MEASURES: Odds of hospital readmissions within a 28-day or 30-day period and ED revisits within a 7-day period. RESULTS: We generated 4830 citations from all data sources, of which 49 (12 paediatric; 36 adult; 1 with both adult and paediatric) were included. In our meta-analysis, language discordant adult patients had increased odds of hospital readmissions (OR 1.11, 95% CI 1.04 to 1.18). Among the 4 studies that verified interpretation services for language discordant patient-clinician interactions, there was no difference in readmission (OR 0.90, 95% CI 0.77 to 1.05), while studies that did not specify interpretation service access/use found higher odds of readmission (OR 1.14, 95% CI 1.06 to 1.22). Adult patients with a non-dominant language preference had higher odds of ED revisits (OR 1.07, 95% CI 1.004 to 1.152) compared with adults with a dominant language preference. In 5 paediatric studies, children of parents language discordant with providers had higher odds of ED revisits at 72 hours (OR 1.12, 95% CI 1.05 to 1.19) and 7 days (OR 1.02, 95% CI 1.01 to 1.03) compared with patients whose parents had language concordant communications. DISCUSSION: Adult patients with a non-dominant language preference have more hospital readmissions and ED revisits, and children with parents who have a non-dominant language preference have more ED revisits. Providing interpretation services may mitigate the impact of language discordance and reduce hospital readmissions among adult patients. PROSPERO REGISTRATION NUMBER: CRD42022302871.

RESUMO

INTRODUCTION: Programmed cell death ligand-1 (PD-L1) expression may help identify patients with non-small cell lung cancer (NSCLC) who would benefit from immunotherapy. We assessed PD-L1 expression, and epidermal growth factor receptor (EGFR) and V-Ki-Ras2 Kirsten rat sarcoma (KRAS) mutations in NSCLC patients receiving adjuvant chemotherapy. METHODS: Data for stage IB/II/IIIA NSCLC patients (diagnosed: 2001-2012) were retrieved from Danish population-based registries. Tumor tissue samples were tested for PD-L1 expression using VENTANA PD-L1 (SP263) Assay in tumor cells (TC) at ≥25% cutoff and immune cells (IC) at ≥1% and ≥25% cutoffs. KRAS and EGFR mutations were tested using PCR-based assays. Follow-up began 120 days after diagnosis until death/emigration/January 1, 2015, whichever came first. Using Cox proportional hazard regression, hazard ratios (HRs) were computed for overall survival (OS) for each biomarker, adjusting for age, sex, histology, comorbidities, and tissue specimen age. RESULTS: Among 391 patients identified, 40.4% had stage IIIA disease, 49.9% stage II, and 8.7% stage IB. PD-L1-TC was observed in 38% of patients, EGFR mutations in 4%, and KRAS mutations in 29%. KRAS mutations were more frequent among patients with PD-L1 TC≥25% versus TC<25% (37% versus 24%). OS was not associated with PD-L1 TC≥25% versus TC<25% (stage II: adjusted HR = 1.15 [95% confidence interval: 0.66-2.01]; stage IIIA: 0.72 [0.44-1.19]). No significant association was observed with OS and PD-L1-IC ≥1% and ≥25%. EGFR and KRAS mutations were not associated with a prognostic impact. CONCLUSION: A prognostic impact for NSCLC patients receiving adjuvant chemotherapy was not associated with PD-L1 expression, or with EGFR and KRAS mutations.

RESUMO

PURPOSE: Biomarkers that predict response to immune checkpoint inhibitors (ICI) in recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) are needed. This retrospective study assessed tumor mutational burden (TMB) and outcomes in the phase II HAWK and CONDOR and phase III EAGLE studies of durvalumab with or without tremelimumab in platinum-resistant R/M HNSCC. PATIENTS AND METHODS: Tumor samples from HAWK/CONDOR (N = 153) and blood samples from EAGLE (N = 247) were analyzed for TMB. Associations with survival were evaluated for tissue TMB (tTMB) at cutoffs from 10 to 20 mutations/megabase (mut/Mb) and for blood plasma TMB (bTMB) at cutoffs from 8 to 24 mut/Mb. RESULTS: In HAWK/CONDOR, overall survival (OS) with durvalumab with or without tremelimumab was longer for high versus low tTMB: statistically significant differences were observed with durvalumab plus tremelimumab at tTMB ≥ 10 mut/Mb [HR, 0.52 (95% confidence interval, CI, 0.28-0.98)] and tTMB ≥ 12 mut/Mb [HR, 0.46 (95% CI, 0.24-0.86)]. In EAGLE, a significant OS benefit versus chemotherapy was observed with durvalumab and durvalumab plus tremelimumab at bTMB≥16 mut/Mb [HR, 0.39 (95% CI, 0.20-0.76) and 0.38 (95% CI, 0.19-0.78), respectively] but not bTMB < 16 mut/Mb [HR, 0.92 (0.61-1.37) and 0.92 (95% CI, 0.62-1.36), respectively]. A significant progression-free survival benefit was also observed in the ICI arms versus chemotherapy at bTMB ≥ 16 mut/Mb. CONCLUSIONS: Findings support TMB as a biomarker for predicting survival in patients with platinum-resistant R/M HNSCC treated with ICIs. The analysis of EAGLE demonstrated that bTMB was predictive of survival with ICI treatment versus chemotherapy in a large, randomized controlled study population.

RESUMO

INTRODUCTION: NEPTUNE, a phase 3, open-label study, evaluated first-line durvalumab plus tremelimumab versus chemotherapy in metastatic NSCLC (mNSCLC). METHODS: Eligible patients with EGFR and ALK wild-type mNSCLC were randomized (1:1) to first-line durvalumab (20 mg/kg every 4 weeks until progression) plus tremelimumab (1 mg/kg every 4 weeks for up to four doses) or standard chemotherapy. Randomization was stratified by tumor programmed death-ligand 1 expression (≥25% versus <25%), tumor histologic type, and smoking history. The amended primary end point was overall survival (OS) in patients with blood tumor mutational burden (bTMB) greater than or equal to 20 mutations per megabase (mut/Mb). Secondary end points included progression-free survival (PFS) in patients with bTMB greater than or equal to 20 mut/Mb and safety and tolerability in all treated patients. RESULTS: As of June 24, 2019, 823 patients were randomized (intention-to-treat [ITT]); 512 (62%) were bTMB-evaluable, with 129 of 512 (25%) having bTMB greater than or equal to 20 mut/Mb (durvalumab plus tremelimumab [n = 69]; chemotherapy [n = 60]). Baseline characteristics were balanced in the intention-to-treat. Among patients with bTMB greater than or equal to 20 mut/Mb, OS improvement with durvalumab plus tremelimumab versus chemotherapy did not reach statistical significance (hazard ratio 0.71 [95% confidence interval: 0.49-1.05; p = 0.081]; median OS, 11.7 versus 9.1 months); the hazard ratio for PFS was 0.77 (95% confidence interval, 0.51-1.15; median PFS, 4.2 versus 5.1 months). In the overall safety population, incidence of grade 3 or 4 treatment-related adverse events was 20.7% (durvalumab plus tremelimumab) and 33.6% (chemotherapy). CONCLUSIONS: NEPTUNE did not meet its primary end point of improved OS with durvalumab plus tremelimumab versus chemotherapy in patients with mNSCLC and bTMB greater than or equal to 20 mut/Mb. Despite the amended study design, with a resultant small primary analysis population, therapeutic activity was aligned with expectations based on mechanistic biology and previous studies.

RESUMO

The impact of abortion stigma is broad. Stigma impacts abortion providers, abortion patients and the broader community. Understanding how race and culture affect aspects of abortion stigma may be an important piece of expanding access to and support of abortion. We conducted a systematic search for studies involving abortion stigma and race in PubMed, PubMed Central, Embase, PsycINFO, Sociological Abstracts, Social Services Abstracts, GenderWatch and Ethnic NewsWatch on 7 January 2020. Articles were eligible for inclusion if they explored stigma and included participant race and/or ethnicity, were in English, and included original research. Thirty studies were included in the final review, including 11 quantitative studies, 9 qualitative studies, 4 mixed methods studies and 6 dissertations. Most studies provided basic racial and demographic data but did not provide racial differences in experiences of abortion stigma. Three quantitative studies found that women of colour had different experiences of abortion stigma compared to White women. Non-peer-reviewed studies of qualitative PhD-level dissertation research found that race, culture, religion and immigration had unique and complex effects on abortion stigma experienced by Latinx women. While abortion stigma is common, we found that there is a lack of research contextualising the racialisation of the United States. Quantitative studies found that women of colour experience abortion stigma at lower levels compared to White women. However, qualitative analyses of experiences suggest that quantitative measures of abortion stigma may not capture unique aspects of abortion stigma as experienced by women of colour.

RESUMO

BACKGROUND: Internationally, strategies focusing on reducing alcohol-related harms in homeless populations with severe alcohol use disorder (AUD) continue to gain acceptance, especially when conventional modalities focused on alcohol abstinence have been unsuccessful. One such strategy is the managed alcohol program (MAP), an alcohol harm reduction program managing consumption by providing eligible individuals with regular doses of alcohol as a part of a structured program, and often providing resources such as housing and other social services. Evidence to the role of MAPs for individuals with AUD, including how MAPs are developed and implemented, is growing. Yet there has been limited collective review of literature findings. METHODS: We conducted a scoping review to answer, "What is being evaluated in studies of MAPs? What factors are associated with a successful MAP, from the perspective of client outcomes? What are the factors perceived as making them a good fit for clients and for communities?" We first conducted a systematic search in PubMed, Embase, PsycINFO, CINAHL, Sociological Abstracts, Social Services Abstracts, and Google Scholar. Next, we searched the gray literature (through focused Google and Ecosia searches) and references of included articles to identify additional studies. We also contacted experts to ensure relevant studies were not missed. All articles were independently screened and extracted. RESULTS: We included 32 studies with four categories of findings related to: (1) client outcomes resulting from MAP participation, (2) client experience within a MAP; (3) feasibility and fit considerations in MAP development within a community; and (4) recommendations for implementation and evaluation. There were 38 established MAPs found, of which 9 were featured in the literature. The majority were located in Canada; additional research works out of Australia, Poland, the USA, and the UK evaluate potential feasibility and fit of a MAP. CONCLUSIONS: The growing literature showcases several outcomes of interest, with increasing efforts aimed at systematic measures by which to determine the effectiveness and potential risks of MAP. Based on a harm reduction approach, MAPs offer a promising, targeted intervention for individuals with severe AUD and experiencing homelessness. Research designs that allow for longitudinal follow-up and evaluation of health- and housing-sensitive outcomes are recommended.

RESUMO

BACKGROUND: Disclosure of medical errors, in which a health care provider informs the patient/family of the error and takes responsibility, is an ethical imperative. Little is known about how medical error disclosure preferences or perceptions may vary for patients who are people of color, are older, or have lower educational attainment. METHODS: The researchers conducted a narrative review on medical errors and disclosure. Included were studies in high-income countries that included a predominantly marginalized population, defined by any one of the following: older age adults (mean age > 65 years); low educational attainment (> 55% of participants with less than a high school education); and/or racial/ethnic minority (< 55% of participants identifying as non-Hispanic white for US studies). RESULTS: The literature search yielded 3,050 articles, resulting in 6 studies included for analysis. Four studies used hypothetical vignettes; 1 used focus groups, and 1 used a survey. Three studies met the marginalized population criteria based on education; 3 met the criteria based on race/ethnicity. No study met the inclusion criteria for age. All 6 articles examined patient preferences for disclosure, and 2 studies also examined patient perceptions of disclosure. Overall, participants preferred that medical errors be disclosed to them. Most of the studies lacked multiple regression analysis to investigate differences in disclosure preferences by race/ethnicity, age, and education. CONCLUSION: Participants from marginalized populations may have similar disclosure preferences to white and highly educated participants. Future studies should aim to examine differences in error disclosure preferences among patients who have experienced adverse events across race/ethnicity, educational attainment, and age.

RESUMO

Programmed cell death ligand-1 (PD-L1), expressed on both tumor cells (TC) and tumor-associated immune cells (IC), has been shown to be a useful biomarker and predictive of response to anti-PD-L1 agents in certain tumor types. In recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC), there is a growing interest in the role of PD-L1 expression on ICs, as well as TCs, for predicting response to immune checkpoint inhibitors. Using pooled data from the phase II HAWK and CONDOR studies, we investigated the association of baseline PD-L1 expression with durvalumab efficacy in patients with R/M HNSCC. To determine an optimal PD-L1 cut-off point for predicting survival, we assessed PD-L1 expression levels at different TC and IC cut-off points in patients treated with durvalumab. Longer survival was associated with higher TC membrane PD-L1 expression and IC staining. When the combined TC/IC algorithm was applied, a cut-off point for PD-L1 expression of ≥50% on TCs or ≥25% on ICs (TC ≥ 50%/IC ≥ 25%) showed a higher objective response rate (17.2% vs. 8.8%), longer median progression-free survival (2.8 vs. 1.9 months), and longer median overall survival (8.4 vs. 5.4 months) in the PD-L1-high versus PD-L1-low/negative patient populations, respectively. A scoring algorithm combining PD-L1 expression on TCs and ICs using the cut-off point TC ≥ 50%/IC ≥ 25% was optimal for identifying patients with HNSCC most likely to benefit from durvalumab treatment. The new algorithm is robust and can be reproducibly scored by trained pathologists. Significance: A novel algorithm for PD-L1 expression using the cut-off point TC ≥ 50%/IC ≥ 25% is robust for identifying patients with HNSCC most likely to benefit from durvalumab treatment and can be reproducibly scored by trained pathologists.

RESUMO

Contraceptive stock-outs are a world-wide problem, yet published research on the impacts of contraceptive stock-outs have not been comprehensively reviewed and synthesised. This systematic review highlights findings about the impacts of contraceptive stock-outs on users, providers, and facilities and identifies topics that should be explored to ensure everyone can access their preferred method of contraception. We systematically searched PubMed, Embase, Web of Science, Popline, and JSTOR for studies addressing the impacts of contraceptive stock-outs. Of 435 studies, 25 publications addressed the impacts of contraceptive stock-outs. Only two articles focused solely on contraceptive stock-outs; the remaining studies examined stock-outs alongside other factors that may influence contraceptive service provision. Studies discussed how stock-outs limited individuals' ability to use their preferred contraceptive method, influenced where contraceptive methods were obtained and how much they cost, and limited providers' and facilities' abilities to provide contraceptive care. Comparing the impacts of contraceptive stock-outs across studies was challenging, as reliability of stock was sometimes not distinguished from overall method availability, and studies used variable methods to measure stock-outs. Evidence presented in this review can inform efforts to ensure that preferred contraceptive methods are consistently available and accessible to all.

RESUMO

Significance: Chronic venous disease (CVD) is prevalent in the aging population and leads to venous leg ulcers (VLUs). These wounds can last and recur for years, significantly impacting quality of life. A large body of literature exists on CVD and VLU diagnosis and treatment. Multiple algorithms, guidelines, and consensus documents have been published on this topic, highlighting the importance of this issue in clinical practice. However, these documents are not fully aligned with each other. Recent Advances: The latest update of the internationally used classification system for CVD was recently published. Our review aims to summarize the existing information to provide an educational tool for clinicians new to this topic, and to highlight the commonalities between the published recommendations. Critical issues: VLUs need to be treated with consideration for the extent of venous disease present in the patient. This requires a good understanding of the various components involved and the possible additional concomitant conditions by the first-line clinician who encounters the patient. A multidisciplinary team is necessary for a successful overall treatment plan, and this plan should be tailored to each patient's specific needs and lifestyle. Future Directions: Compression is still the mainstay of treatment for CVD and VLUs. Compression is needed long term, but it does not suffice by itself to prevent recurrences without interventional correction. Venous intervention should be offered early to prevent or slow disease progression and reduce recurrence.

RESUMO

Existing approaches for cancer diagnosis are inefficient in the use of diagnostic tissue, and decision-making is often sequential, typically resulting in delayed treatment initiation. Future diagnostic testing needs to be faster and optimize increasingly complex treatment decisions. We envision a future where comprehensive testing is routine. Our approach, termed the "combiome," combines holistic information from the tumor, and the patient's immune system. The combiome model proposed here advocates synchronized up-front testing with a panel of sensitive assays, revealing a more complete understanding of the patient phenotype and improved targeting and sequencing of treatments. Development and eventual adoption of the combiome model for diagnostic testing may provide better outcomes for all cancer patients, but will require significant changes in workflows, technology, regulations, and administration. In this review, we discuss the current and future testing landscape, targeting of personalized treatments, and technological and regulatory advances necessary to achieve the combiome.

RESUMO

Adenosine is extensively distributed in the central and peripheral nervous systems, where it plays a key role as a neuromodulator. It has long been implicated in the pathogenesis of progressive neurogenerative disorders such as Parkinson's disease, and there is now growing interest in its role in amyotrophic lateral sclerosis (ALS). The motor neurons affected in ALS are responsive to adenosine receptor function, and there is accumulating evidence for beneficial effects of adenosine A2A receptor antagonism. In this article, we focus on recent evidence from ALS clinical pathology and animal models that support dynamism of the adenosinergic system (including changes in adenosine levels and receptor changes) in ALS. We review the possible mechanisms of chronic neurodegeneration via the adenosinergic system, potential biomarkers and the acute symptomatic pharmacology, including respiratory motor neuron control, of A2A receptor antagonism to explore the potential of the A2A receptor as target for ALS therapy.

RESUMO

BACKGROUND: PD-L1 expression on tumor cells (TCs) or immune cells (ICs) may be used as a prognostic marker for survival in patients with NSCLC. We characterized PD-L1 expression on TCs or ICs in a patient cohort with NSCLC to determine associations between PD-L1 expression and overall survival (OS), according to EGFR and KRAS mutation status. METHODS: Danish patients aged >18 years diagnosed with NSCLC before 2014 on first- (N = 491), second- (N = 368), or third-line (N = 498) therapy were included. Data were extracted from population-based medical registries. Tumor samples from pathology archives were tested for biomarkers. High PD-L1 expression was defined as expression on ≥25 % of TCs or ICs based on first diagnostic biopsy or surgical resection. KRAS and EGFR mutation status were tested using PCR-based assays. Cox regression analysis was used to compute adjusted HRs and associated 95 % CIs. RESULTS: PD-L1 TC and IC ≥ 25 % were observed in 24.3 %-31.0 % and 11.7-14.7 % of patients, respectively. EGFR and KRAS mutations were detected in 4.7 %-8.8 % and 26.5 %-30.7 % of patients, respectively. PD-L1 TC ≥ 25 % was not associated with survival advantage in first- (HR = 0.96, 95 % CI: 0.75-1.22), second- (1.08, 0.81-1.42), or third-line (0.94, 0.74-1.20) therapy. PD-L1 IC ≥ 25 % was associated with survival advantage in second-line (HR = 0.56, 95 % CI: 0.36-0.86) and third-line (0.69, 0.49-0.97) but not first-line (1.00, 0.70-1.41) therapy. CONCLUSION: No association was observed between PD-L1 TC ≥ 25 % and OS in any therapy line. PD-L1 IC ≥ 25 % may confer survival benefit among some patients who reach second-line therapy.

RESUMO

Mobile health (mHealth) technologies improve hypertension outcomes, but it is unknown if this benefit applies to all populations. This review aimed to describe the impact of mHealth interventions on blood pressure outcomes in populations with disparities in digital health use. We conducted a systematic search to identify studies with systolic blood pressure (SBP) outcomes located in urban settings in high-income countries that included a digital health disparity population, defined as mean age ≥65 years; lower educational attainment (≥60% ≤high school education); and/or racial/ethnic minority (<50% non-Hispanic White for US studies). Interventions were categorized using an established self-management taxonomy. We conducted a narrative synthesis; among randomized clinical trials (RCTs) with a six-month SBP outcome, we conducted random-effects meta-analyses. Twenty-nine articles (representing 25 studies) were included, of which 15 were RCTs. Fifteen studies used text messaging; twelve used mobile applications. Studies were included based on race/ethnicity (14), education (10), and/or age (6). Common intervention components were: lifestyle advice (20); provision of self-monitoring equipment (17); and training on digital device use (15). In the meta-analyses of seven RCTs, SBP reduction at 6-months in the intervention group (mean SBP difference = -4.10, 95% CI: [-6.38, -1.83]) was significant, but there was no significant difference in SBP change between the intervention and control groups (p = 0.48). The use of mHealth tools has shown promise for chronic disease management but few studies have included older, limited educational attainment, or minority populations. Additional robust studies with these populations are needed to determine what interventions work best for diverse hypertensive patients.

RESUMO

BACKGROUND: Initiatives to identify and intervene on patients' socioeconomic needs in the context of health care delivery are expanding. Little information has been compiled across studies on health care providers' knowledge, attitudes, beliefs, and behaviors (KABB) regarding socioeconomic risk screening and referral interventions. METHODS: We conducted a systematic scoping review of providers' KABB related to health care-based socioeconomic risk screening and referral interventions using several search engines. Included studies assessed health care providers' KABB about screening and interventions conducted in clinical settings. RESULTS: Of 14,757 studies evaluated, 53 were eligible for inclusion. Study designs were heterogeneous. Outcome measures included attitudes and beliefs (n = 42), provider behaviors (n = 35), and provider knowledge (n = 26). The majority of providers expressed positive attitudes toward addressing patients' socioeconomic risks. Participants endorsed concerns regarding insufficient knowledge and resources, time and workflow disruption, and potential negative impacts of screening and referral programs on relationships. Exposure to screening and referral programs led to increases in providers' positive attitudes, socioeconomic risk screening rates, and reported knowledge about intervention options. CONCLUSIONS: Participation in screening and referral programs seems to influence providers' perception of implementation barriers. Future research should explore providers' concerns about addressing identified risks.

RESUMO

Justice-involved youth experience high rates of adverse childhood experiences (ACEs), placing them in great need of behavioral health treatment and risk for continued justice involvement. Policymakers, government agencies, and professionals working with justice-involved youth have called for trauma-informed juvenile justice reform. Yet, there is currently no available review of the literature on ACEs and their impact on justice-involved youths' psychological, legal, and related (e.g., academic) outcomes to rigorously guide such reform efforts. The current systematic scoping review synthesizes existing literature related to the impact of ACEs on justice-involved youth and offers recommendations for data-driven intervention along the Sequential Intercept Model, which describes five different points of justice system contact (i.e., first arrest, court diversion, detention, and community supervision) in which there is opportunity to intervene and improve youth behavioral health, legal, and associated outcomes. Eight unique studies were included in 40 articles examining ACEs among justice-involved youth; 38% were longitudinal or prospective analyses and none were intervention studies. Studies included delinquency (e.g., recidivism; n = 5), psychiatric (n = 4), substance use (n = 3), and other (n = 2; e.g., academic, pregnancy) outcomes, documenting high prevalence of ACEs and significant associations between ACEs and a variety of outcomes. Implications for clinical services (e.g., targeting youth dysregulation and aggression), agency context (e.g., training police officers in trauma-responsive practices), and system-level changes (e.g., intervening at the time of first ACE documentation such as parent's arrest) are discussed.

RESUMO

CONTEXT: Evidence-based guidelines for active surveillance (AS), a treatment option for men with low-risk prostate cancer, recommend regular follow-up at periodic intervals to monitor disease progression. However, gaps in monitoring can lead to delayed detection of cancer progression, leading to a missed window of curability. OBJECTIVE: We aimed to identify the extent to which real-world observational studies reported adherence to monitoring protocols among prostate cancer patients on AS. When reported, we sought to characterize definitions of adherence. EVIDENCE ACQUISITION: We systematically reviewed observational studies assessing outcomes of prostate cancer patients on AS, published before March 22, 2019 in PubMed, Embase, and CENTRAL. Adherence definitions were considered time bound if they included prespecified time and binary if adherence was assessed but did not specify a time interval. We assessed study quality using the Strengthening the Reporting of Observational Studies in Epidemiology checklist. EVIDENCE SYNTHESIS: Forty-five studies met our inclusion criteria. Eleven studies did not report any data on adherence to AS protocols. Twenty-five studies did not explicitly measure adherence, but provided relevant data (eg, number of patients who received a repeat biopsy). Six studies reported adherence using a time-bound definition, while three studies used a binary definition. Twenty-three studies provided information on patients lost to follow-up. CONCLUSIONS: Most studies reporting outcomes of patients on AS did not measure or report adherence. When reported, adherence was often not time specific. As some AS patients will benefit from maintaining a window of curability, clinical practices and future studies should track and report adherence and associated factors. PATIENT SUMMARY: We reviewed real-world observational studies examining outcomes of prostate cancer patients on active surveillance. Most studies did not clearly define or report adherence to monitoring protocols, which is important to consider for appropriate disease management.
