Abstract
INTRODUCTION Strong and ever-growing evidence highlights the effectiveness of recovery housing in supporting and sustaining substance use disorder (SUD) recovery, especially when augmented by intensive support that includes assertive linkages to community services. This study aims to evaluate a pilot intensive recovery support (IRS) intervention for individuals (n = 175) entering certified Level II and III recovery residences. These individuals met at least three out of five conditions (no health insurance; no driving license; substance use in the last 14 days; current unemployment; possession of less than $75 capital). The study assesses the impact of the IRS on engagement, retention, and changes in recovery capital, compared to the business-as-usual Standard Recovery Support (SRS) approach (n = 1758). METHODS The study employed quasi-experimental techniques to create weighted and balanced counterfactual groups. These groups, derived from the Recovery Capital assessment tool (REC-CAP), enabled comparison of outcomes between people receiving IRS and those undergoing SRS. RESULTS After reweighting for resident demographics, service needs, and barriers to recovery, those receiving IRS exhibited improved retention rates, reduced likelihood of disengagement, and growth in recovery capital after living in the residence for 6-9 months. CONCLUSION The results from this pilot intervention indicate that intensive recovery support, which integrates assertive community linkages and enhanced recovery coaching, outperforms a balanced counterfactual group in engagement, length of stay, and recovery capital growth. We suggest that this model may be particularly beneficial to those entering Level II and Level III recovery housing with lower levels of recovery capital at admission.

Abstract
INTRODUCTION Over 90% of children with CHD survive into adulthood and require lifelong cardiology care. Delays in care predispose patients to cardiac complications. We sought to determine the time interval to accessing adult CHD care beyond what was recommended by the referring paediatric cardiologist (excess time) and determine risk factors for prolonged excess time. MATERIALS AND METHODS Retrospective cohort study including all patients in the province of Alberta, Canada, age 16-18 years at their last paediatric cardiology visit, with moderate or complex lesions. Excess time between paediatric and adult care was defined as the interval (months) between the final paediatric visit and the first adult visit, minus the recommended interval between these appointments. Patients whose first adult CHD appointment occurred earlier than the recommended interval were assigned an excess time of zero. RESULTS We included 286 patients (66% male, mean age 17.6 years). Mean excess time was 7.9 ± 15.9 months. Twenty-nine (10%) had an excess time > 24 months. Not having a pacemaker (p = 0.03) and not needing cardiac medications at transfer (p = 0.02) were risk factors for excess time >3 months. Excess time was not influenced by CHD complexity. DISCUSSION The mean delay to first adult CHD appointment was almost 8 months longer than recommended by referring paediatric cardiologists. Not having a pacemaker and not needing cardiac medication(s) were risk factors for excess time > 3 months. Greater outpatient resources are required to accommodate the growing number of adult CHD survivors.

Abstract
Pressure ulcers (PUs) remain a chronic health problem with severe impacts on healthcare systems. Early detection is crucial to providing effective interventions. However, detecting PUs currently relies on subjective tissue evaluations, such as visual skin assessment, precluding interventions prior to the development of visible tissue damage. There is an unmet need for solutions that can detect early tissue damage before visual and tactile signs occur. Assessments based on sub-epidermal moisture (SEM) measurements represent an opportunity for robust and objective early detection of PUs, preventing broken skin PUs in more high-risk patients at high-risk anatomical locations. While SEM assessment technology has been validated in computational, bench and tissue phantom models, validation in soft tissue was absent. In this study, we successfully validated the ability of a commercially available SEM assessment device to measure and detect sub-epidermal moisture changes in a novel ex vivo porcine soft tissue model of localised oedema. When controlled and incremental fluid volumes (Phosphate Buffer Solution) were injected into porcine soft tissues, statistically significant differences were found in SEM values between fluid-injected sites, representing an inflammatory oedematous condition, and healthy tissue control sites, as measured by the SEM device. The device provided reproducible readings by detecting localised oedema changes in soft tissues, reflecting the build-up of fluid as small as 1 ml into the underlying tissue. Spatial characterization experiments described the ability of the device technology to differentiate between healthy and oedematous tissue. Our findings validate the use of SEM assessment technology to measure and quantify localized oedema.

Abstract
A systematic review with meta-analysis was conducted to establish the impact of menopause health education on quality of life (QoL) among menopausal women. Research suggests that specific educational programs can support and enable women during the physical and emotional transition through menopause. The CINAHL, Medline, APA, Embase and Google Scholar databases were searched between 30 November 2021 and 9 January 2022 using the PRISMA guidelines. The Cochrane risk of bias tool was used to critically evaluate the included studies. Review Manager software was used to conduct the meta-analysis of suitable studies. Eight papers were eligible for this review. The participants were aged between 40 and 60 years, with diagnosis of menopause stemming from changes in the menstrual cycle to a last menstrual period of 7 years. Follow-up data were collected between 1 and 4 months post education. Meta-analysis of both the primary outcome (QoL) and secondary outcome (symptom control) demonstrated statistically significant improvements post intervention. Papers not suitable for meta-analysis were reviewed narratively; two papers assessing the primary outcome (QoL) demonstrated an improvement, but only one to a statistically significant level. Secondary outcomes revealed improvements, with all bar one paper doing so to statistical significance. Menopause health education demonstrated an improvement in both QoL and symptom control in menopausal women; however, given some weaknesses in the included studies, further research is justified. Limitations include participants' level of education, geographical location, risk of bias, that only half of the papers addressed participant use of hormone replacement therapy and length of follow-up.

Abstract
Over the past decade, multiple trials, including the precision medicine trial National Cancer Institute-Molecular Analysis for Therapy Choice (NCI-MATCH, EAY131, NCT02465060) have sought to determine if treating cancer based on specific genomic alterations is effective, irrespective of the cancer histology. Although many therapies are now approved for the treatment of cancers harboring specific genomic alterations, most patients do not respond to therapies targeting a single alteration. Further, when antitumor responses do occur, they are often not durable due to the development of drug resistance. Therefore, there is a great need to identify rational combination therapies that may be more effective. To address this need, the NCI and National Clinical Trials Network have developed NCI-ComboMATCH, the successor to NCI-MATCH. Like the original trial, NCI-ComboMATCH is a signal-seeking study. The goal of ComboMATCH is to overcome drug resistance to single-agent therapy and/or utilize novel synergies to increase efficacy by developing genomically-directed combination therapies, supported by strong preclinical in vivo evidence. Although NCI-MATCH was mainly comprised of multiple single-arm studies, NCI-ComboMATCH tests combination therapy, evaluating both combination of targeted agents as well as combinations of targeted therapy with chemotherapy. Although NCI-MATCH was histology agnostic with selected tumor exclusions, ComboMATCH has histology-specific and histology-agnostic arms. Although NCI-MATCH consisted of single-arm studies, ComboMATCH utilizes single-arm as well as randomized designs. NCI-MATCH had a separate, parallel Pediatric MATCH trial, whereas ComboMATCH will include children within the same trial. We present rationale, scientific principles, study design, and logistics supporting the ComboMATCH study.

Abstract
PURPOSE Cyclin D/CDK4/6 is critical in controlling the G1 to S checkpoint. CCND, the gene encoding cyclin D, is known to be amplified in a variety of solid tumors. Palbociclib is an oral CDK4/6 inhibitor, approved in advanced breast cancer in combination with endocrine therapy. We explored the efficacy of palbociclib in patients with nonbreast solid tumors containing an amplification in CCND1, 2, or 3. PATIENTS AND METHODS Patients with tumors containing a CCND1, 2, or 3 amplification and expression of the retinoblastoma protein were assigned to subprotocol Z1B and received palbociclib 125 mg once daily for 21 days of a 28-day cycle. Tumor response was assessed every two cycles. RESULTS Forty patients were assigned to subprotocol Z1B; 4 patients had outside assays identifying the CCND1, 2, or 3 amplification and were not confirmed centrally; 3 were ineligible and 2 were not treated (1 untreated patient was also ineligible), leaving 32 evaluable patients for this analysis. There were no partial responses; 12 patients (37.5%) had stable disease as best response. There were seven deaths on study, all during cycle 1 and attributable to disease progression. Median progression-free survival was 1.8 months. The most common toxicities were leukopenia (n = 21, 55%) and neutropenia (n = 19, 50%); neutropenia was the most common grade 3/4 event (n = 12, 32%). CONCLUSIONS Palbociclib was not effective at treating nonbreast solid tumors with a CCND1, 2, or 3 amplification in this cohort. These data do not support further investigation of single-agent palbociclib in tumors with CCND1, 2, or 3 amplification.

Abstract
PURPOSE NCI-MATCH is a precision medicine trial using genomic testing to allocate patients with advanced malignancies to targeted treatment subprotocols. This report combines two subprotocols evaluating trametinib, a MEK1/2 inhibitor, in patients with Neurofibromatosis 1 (NF1[S1] or GNA11/Q [S2]) altered tumors. METHODS Eligible patients had tumors with deleterious inactivating NF1 or GNA11/Q mutations by the customized Oncomine AmpliSeq panel. Prior MEK inhibitor treatment was excluded. Glioblastomas (GBMs) were permitted, including malignancies associated with germline NF1 mutations (S1 only). Trametinib was administered at 2 mg once daily over 28-day cycles until toxicity or disease progression. Primary end point was objective response rate (ORR). Secondary end points included progression-free survival (PFS) at 6 months, PFS, and overall survival. Exploratory analyses included co-occurring genomic alterations and PTEN loss. RESULTS Fifty patients were eligible and started therapy: 46 with NF1 mutations (S1) and four with GNA11 mutations (S2). In the NF1 cohort, nonsense single-nucleotide variants were identified in 29 and frameshift deletions in 17 tumors. All in S2 had nonuveal melanoma and GNA11 Q209L variant. Two partial responses (PR) were noted in S1, one patient each with advanced lung cancer and GBM for an ORR of 4.3% (90% CI, 0.8 to 13.1). One patient with melanoma in S2 had a PR (ORR, 25%; 90% CI, 1.3 to 75.1). Prolonged stable disease (SD) was also noted in five patients (four in S1 and one in S2) with additional rare histologies. Adverse events were as previously described with trametinib. Comutations in TP53 and PIK3CA were common. CONCLUSION Although these subprotocols did not meet the primary end point for ORR, significant responses or prolonged SD noted in some disease subtypes warrants further investigation.

Abstract
The objective of this study was to investigate the effect of increasing stocking rate (SR) and extending grazing season (GS) length on pasture and animal productivity on a marginal, poorly draining soil type. The study was a multiyear (2017 to 2020, inclusive) whole farm systems evaluation with a 2 × 2 factorial experimental arrangement of treatments. The systems evaluated comprised 2 GS lengths, average (AGS; 205 d) and extended (EGS; 270 d), and the 2 whole farm stocking rates were medium (2.5 cows/ha) and high (2.9 cows/ha). We used this study design to create 4 grazing system intensities (500, 600, 700, and 800 cow grazing days per hectare per year). In 2017, cows were randomly allocated to 1 of the 4 whole farm systems precalving and remained on the same treatments for the duration of the study. We found no significant differences in total average annual pasture production [14,133 ± 538 kg of dry matter (DM) per hectare] or sward chemical composition between GS and SR treatments over the 4-yr period, with the exception of average crude protein content, which was lower for EGS (211 g/kg DM) compared with AGS (218 g/kg DM). Grazed pasture production was significantly increased in EGS treatments (+758 kg of DM/ha) compared with AGS (9,917 kg of DM/ha), whereas conserved silage DM production was greater for AGS (+716 kg of DM/ha) compared with EGS (3,583 kg of DM/ha). Neither GS nor SR had a significant effect on daily or cumulative lactation milk and fat plus protein production per cow (5,039 and ±440 kg, respectively). Increasing SR resulted in increased milk fat plus protein yield per hectare based on increased grazed pasture utilization. These results add further credence to the important additive contributions of both extended grazing and SR intensification to achieve high levels of grazed pasture utilization and milk production per hectare while reducing supplementary feed requirements within spring-calving grazing systems.

Abstract
Background There is growing evidence on the importance of a gendered understanding of recovery. Gender differences have been reported in relation to the nature and extent of substance use, pathways to and through substance use disorder and recovery capital acquisition and maintenance. There is little existing research on factors associated with recovery capital growth by gender. Methods The current paper uses the European Life in Recovery database to assess specific domains of the Strengths and Barriers Recovery Scale (SABRS) that best predict growth of recovery capital amongst people in recovery from drug addiction. The 1313 participants were drawn from the REC-PATH study and recruited by the Recovery Users Network (RUN) from across Europe. Bivariate and multivariate analyses were performed to identify relationships between specific SABRS items and gender, as well as differences in the dimensions of the SABRS scale most likely to predict recovery capital growth by gender. Results Between their time in active addiction and in recovery, females show greater growth in strengths, despite females reporting fewer recovery strengths during active addiction than males, and males have greater reductions in barriers to recovery compared to females. Multivariate analyses show that strengths specifically related to prosocial meaningful activities are found to be highly significant for growth of recovery capital amongst males, whereas strengths related to both prosocial meaningful activities and general health management seem particularly relevant for growth of recovery capital amongst females. Conclusions We conclude that this further demonstration of gender differences in recovery pathways should suggest gender-specific approaches adopted in recovery community organisations to address these different needs.

Abstract
Painful life events have been highlighted as being instrumental in promoting change during drug addiction recovery. This paper attempts to integrate the ‘pains of desistance’ approach into a recovery capital framework. It explores the life courses of 30 people in drug addiction recovery who had previously had a problem with an illicit substance to explore the role of the pains of recovery (potential push factors) alongside different forms of recovery capital (pull factors) at key turning points of change during recovery. Findings demonstrate that pull factors linked to CHIME were significant in promoting positive changes. Turning points acted as antidotes to pains experienced in early recovery. Three antidotes appeared to be gender specific. Implications highlight the need for greater access to community capital pathways. It advocates the need to dispel the myth for a rock bottom moment and for a more macro conceptualisation of drug addiction recovery.

Abstract
Abstract
Purpose: Mutations in BRAF at codons other than V600 (non-V600) and BRAF fusions confer dependence on RAF-MEK-ERK pathway. BVD-523FB (ulixertinib) is a small molecule that potently inhibits both ERK1 and ERK2 protein kinases in the sub-nanomolar range. Based on the reports of early clinical activity in the phase 1 trial, including in non-V600 BRAF mutations, subprotocol Z1L (EAY131-Z1L) sought to investigate the clinical activity of ulixertinib in patients with tumors harboring these alterations. Methods: In this single-arm study, patients with BRAF non-V600 mutation or BRAF fusion were given ulixertinib orally at a dose of 600 mg twice daily, continuously for each 28-day cycle until progression or intolerability. The primary endpoint was objective response rate (ORR). Secondary endpoints included progression-free survival (PFS), 6-month PFS, and overall survival (OS). BRAF mutation status was determined by an analytically validated assay in a CLIA-certified laboratory for all patients. Results: From August 2019 to July 2020, 35 patients were enrolled and received protocol treatment on the trial. Among the 34 patients who were eligible, median age was 66.5; 50% were female, 88% were white, 9% black, 1% Asian. Performance status was ECOG PS 1 in 74% of patients, with remaining PS 0. Median number of prior therapies was >3.Tumor types included multiple gastrointestinal malignancies (N=16), lung cancer (N=3), and melanoma (N=3), among others. Mutations were centrally confirmed in 26 patients who were deemed analyzable per protocol. Twenty-two patients had a single nucleotide variant (SNV) in BRAF; one patient had an insertion/deletion (indel) in BRAF, and three patients harbored BRAF fusions. No patients achieved CR or PR, resulting in ORR = 0%. Stable disease was the best response in 7/26 centrally confirmed cases. Median PFS was 1.8 months (90% CI: 1.6, 2.2), 6-month PFS rate was 11% (90% CI: 4%, 22%), and median OS was 4.0 months (90% CI: 2.8, 7.4). Twenty patients (57%) had grade 3 toxicities, and one patient (3%) had grade 4 toxicity; there were no grade 5 toxicities. Most common toxicities include anemia (n=11), diarrhea (n=16), nausea (n=16), vomiting (n=11), fatigue (n=16), increased creatinine (n=12), and acneiform rash (n=14). Conclusion: BVD-523FB (ulixertinib) had no demonstrable evidence of clinical activity in this small, heavily pre-treated population of patients with tumors harboring BRAF fusions, or with non-V600E, non-V600K BRAF mutations

Abstract
The NCI-MATCH was designed to characterize the efficacy of targeted therapies in histology-agnostic driver mutation-positive malignancies. Sub-protocols F and G were developed to evaluate the role of crizotinib in rare tumors that harbored either ALK or ROS1 rearrangements. Patients with malignancies that progressed following at least one prior systemic therapy were accrued to the NCI-MATCH for molecular profiling, and those with actionable ALK or ROS1 rearrangements were offered participation in sub-protocols F or G, respectively. There were five patients who enrolled on Arm F (ALK) and four patients on Arm G (ROS1). Few grade 3 or 4 toxicities were noted, including liver test abnormalities, and acute kidney injury. For sub-protocol F (ALK), the response rate was 50% (90% CI 9.8-90.2%) with one complete response among the 4 eligible patients. The median PFS was 3.8 months, and median OS was 4.3 months. For sub-protocol G (ROS1) the response rate was 25% (90% CI 1.3-75.1%). The median PFS was 4.3 months, and median OS 6.2 months. Data from 3 commercial vendors showed that the prevalence of ALK and ROS1 rearrangements in histologies other than non-small cell lung cancer and lymphoma was rare (0.1% and 0.4% respectively). We observed responses to crizotinib which met the primary endpoint for ALK fusions, albeit in a small number of patients. Despite the limited accrual, some of the patients with these oncogenic fusions can respond to crizotinib which may have a therapeutic role in this setting.

Abstract
PURPOSE PIK3CA mutations frequently contribute to oncogenesis in solid tumors. Taselisib, a potent and selective inhibitor of phosphoinositide 3-kinase, has demonstrated clinical activity in PIK3CA-mutant breast cancer. Whether PIK3CA mutations predict sensitivity to taselisib in other cancer types is unknown. National Cancer Institute-Molecular Analysis for Therapy Choice Arm EAY131-I is a single-arm, phase II study of the safety and efficacy of taselisib in patients with advanced cancers. METHODS Eligible patients had tumors with an activating PIK3CA mutation. Patients with breast or squamous cell lung carcinoma, or whose cancer had KRAS or PTEN mutations, were excluded. Patients received taselisib 4 mg, orally once daily continuously, until disease progression or unacceptable toxicity. The primary end point was objective response rate. Secondary end points included progression-free survival (PFS), 6-month PFS, overall survival (OS), and identification of predictive biomarkers. RESULTS Seventy patients were enrolled, and 61 were eligible and initiated protocol therapy. Types of PIK3CA mutations included helical 41 of 61 (67%), kinase 11 of 61 (18%), and other 9 of 61 (15%). With a median follow-up of 35.7 months, there were no complete or partial responses. Six-month PFS was 19.9% (90% CI, 12.0 to 29.3) and median PFS was 3.1 months (90% CI, 1.8 to 3.7). Six-month OS was 60.7% (90% CI, 49.6 to 70.0) and median OS was 7.2 months (90% CI, 5.9 to 10.0). Individual comutations were too heterogeneous to correlate with clinical outcome. Fatigue, diarrhea, nausea, and hyperglycemia were the most common toxicities, and most were grade 1 and 2. CONCLUSION In this study, taselisib monotherapy had very limited activity in a heterogeneous cohort of heavily pretreated cancer patients with PIK3CA-mutated tumors; the presence of a PIK3CA mutation alone does not appear to be a sufficient predictor of taselisib activity.

Abstract
INTRODUCTION One of the most consequential effects of the COVID-19 lockdowns was a dramatic reduction in travel during peak hours. Transportation modes also shifted-in particular, travel by car became more rare while bicycling saw a resurgence. Given that a typical year sees the most severe bicycle crashes in peak commuter traffic, the shift toward bicycle travel that occurred in 2020 will likely have been accompanied by unique changes in rider behavior (e.g., where and when they choose to ride) as well as the frequency and severity of vehicle-bicycle crashes. METHODS The current study compared weekday bicycle traffic and crashes in Arlington, VA from March-December 2020 with the same period from years prior, 2013-2019. Bicycle traffic data were obtained from 16 embedded counters placed throughout the study area, in both off-road trails and on-road bike lanes. RESULTS We found that 2020 midday traffic nearly doubled compared to the year before, increasing from an average of 68 riders per hour to 120 (+76%). By contrast, morning traffic fell from an average of 87 riders per hour to just 45 (-49%). Change in evening traffic depended on the location of the counters: more evening bicycles were counted on off-road, multi-use trails (+6%) but fewer on on-road lanes (-27%). The changes to 2020 bicycle traffic patterns were also associated with a 28% reduction in bicycle injury crash rate per counted cyclist. CONCLUSION The reduced crash risk observed in 2020 was likely due in part to the reduction of morning, on-road bicycle travel, which past research has found to be particularly dangerous for riders. Conversely, the availability of multi-use off-road trails seems to have been a protective factor against bicycle-motor vehicle crash risk in the face of greater bicycle travel volume.

Abstract
Understanding how mutations affect survivability is a key component to knowing how organisms and complex traits evolve. However, most mutations have a minor effect on fitness and these effects are difficult to resolve using traditional molecular techniques. Therefore, there is a dire need for more accurate and precise fitness measurements methods. Here, we measured the fitness effects in Burkholderia cenocepacia HI2424 mutation accumulation (MA) lines using droplet-digital polymerase chain reaction (ddPCR). Overall, the fitness measurements from ddPCR-MA are correlated positively with fitness measurements derived from traditional phenotypic marker assays (r = 0.297, P = 0.05), but showed some differences. First, ddPCR had significantly lower measurement variance in fitness (F = 3.78, P < 2.6 × 10-13) in control experiments. Second, the mean fitness from ddPCR-MA measurements were significantly lower than phenotypic marker assays (-0.0041 vs -0.0071, P = 0.006). Consistent with phenotypic marker assays, ddPCR-MA measurements observed multiple (27/43) lineages that significantly deviated from mean fitness, suggesting that a majority of the mutations are neutral or slightly deleterious and intermixed with a few mutations that have extremely large effects. Of these mutations, we found a significant excess of mutations within DNA excinuclease and Lys R transcriptional regulators that have extreme deleterious and beneficial effects, indicating that modifications to transcription and replication may have a strong effect on organismal fitness. This study demonstrates the power of ddPCR as a ubiquitous method for high-throughput fitness measurements in both DNA- and RNA-based organisms regardless of cell type or physiology.

Abstract
Abstract
Background: Although genomic changes identified by clinical tumor sequencing may be present in the germline, precision oncology trials have generally not incorporated germline testing and reporting. We describe our experience with clinical reporting of matched tumor and germline results from the NCI-COG Pediatric Molecular Analysis for Therapy Choice (MATCH) trial (NCT03155620).
Design/Method: Patients age 1 to 21 years old with treatment-refractory solid tumors, non-Hodgkin lymphomas, or histiocytic disorders were eligible. DNA and RNA extracted from FFPE tumors were sequenced using Oncomine Assay v.3 with reporting of potentially actionable fusions, amplifications, and mutations, including loss of function variants in tumor suppressor genes. Germline reporting focused on 36 genes from the same DNA panel that convey adult or pediatric cancer susceptibility but does not include all cancer susceptibility genes (e.g. APC, DICER1). Deletions and splice site variants were not reported.
Results: As of June 2020, 1009 patients had been enrolled from 132 COG sites, with tumor and germline testing complete for 868 patients to date. Overall, 62 (7.1%) germline reports included a pathogenic or likely pathogenic germline variant (termed germline findings) in 18 cancer susceptibility genes. This frequency was similar in patients with solid tumors (46/633, 7.3%), CNS tumors (14/204, 6.9%), and lymphomas/histiocytoses (2/31, 6.5%). Variant(s) of potential germline significance were identified in 25% of tumor reports; of these, 74% (163/221) had no germline findings. The proportion of germline findings for genes with >10 reported tumor variants varied: 32% (7/22) in NF1, 25% (3/12) in RB1, 16% (17/108) in TP53 and 0% in ALK (0/21) and PTEN (0/12). Of note, 82% (14/17) of tumor variants in breast cancer susceptibility genes (BRCA1/2, CHEK2 and PALB2) had germline findings. On study intake forms, 25% of patients with germline findings had a “known genetic disease” reported. Oncologists caring for patients with a germline finding were then queried about prior knowledge of a genetic diagnosis. Of 24 respondents, 13 (54%) reported no prior molecular diagnosis of the identified condition.
Conclusions: Coordinated germline and tumor testing revealed clinically relevant cancer susceptibility variants across a spectrum of genes in 7% of pediatric patients with treatment-refractory cancers. This is likely an underestimate of germline findings given test limitations. The parallel tumor/normal reporting approach minimized the need for targeted reflex genetic testing in 19% of study participants and provided new information on cancer susceptibility in germline positive patients to half of the responding oncologists. The NCI-COG Pediatric MATCH trial reporting process can serve as a model for precision oncology trials and clinical tumor profiling.

Abstract
Background The proportion of tumors of various histologies that may respond to drugs targeted to molecular alterations is unknown. NCI-MATCH, a collaboration between ECOG-ACRIN Cancer Research Group and the National Cancer Institute, was initiated to find efficacy signals by matching patients with refractory malignancies to treatment targeted to potential tumor molecular drivers regardless of cancer histology. Methods Trial development required assumptions about molecular target prevalence, accrual rates, treatment eligibility, and enrollment rates as well as consideration of logistical requirements. Central tumor profiling was performed with an investigational next-generation DNA–targeted sequencing assay of alterations in 143 genes, and protein expression of protein expression of phosphatase and tensin homolog, mutL homolog 1, mutS homolog 2, and RB transcriptional corepressor 1. Treatments were allocated with a validated computational platform (MATCHBOX). A preplanned interim analysis evaluated assumptions and feasibility in this novel trial. Results At interim analysis, accrual was robust, tumor biopsies were safe (<1% severe events), and profiling success was 87.3%. Actionable molecular alteration frequency met expectations, but assignment and enrollment lagged due to histology exclusions and mismatch of resources to demand. To address this lag, we revised estimates of mutation frequencies, increased screening sample size, added treatments, and improved assay throughput and efficiency (93.9% completion and 14-day turnaround). Conclusions The experiences in the design and implementation of the NCI-MATCH trial suggest that profiling from fresh tumor biopsies and assigning treatment can be performed efficiently in a large national network trial. The success of such trials necessitates a broad screening approach and many treatment options easily accessible to patients.

Abstract
Importance In the National Cancer Institute Molecular Analysis for Therapy Choice (NCI-MATCH) trial, agents targeting genetic tumor abnormalities are administered to patients. In the NCI-MATCH subprotocol EAY131-Y trial, patients with an AKT1 E17K-mutated metastatic tumor received the pan-AKT inhibitor capivasertib. Objective To assess the objective response rate (ORR) of capivasertib in patients with an AKT1 E17K-mutated tumor. Design, Setting, and Participants Between July 13, 2016, and August 10, 2017, patients in the NCI-MATCH trial were enrolled and assigned to the subprotocol EAY131-Y nonrandomized trial. Patients included adults with an AKT1 E17K-mutated metastatic tumor that had progressed with standard treatment, and these patients were assigned to receive capivasertib. Tumor assessments were repeated every 2 cycles. Data analysis of this evaluable population was performed from November 8, 2019, to March 12, 2020. Interventions The study treatment was capivasertib, 480 mg, orally twice daily for 4 days on and 3 days off weekly in 28-day cycles until disease progression or unacceptable toxic effect. If patients continued hormone therapy for metastatic breast cancer, the capivasertib dose was 400 mg. Main Outcomes and Measures The primary end point was the ORR (ie, complete response [CR] and partial response) according to the Response Evaluation Criteria in Solid Tumors criteria, version 1.1. Secondary end points included progression-free survival (PFS), 6-month PFS, overall survival, and safety. Results In total, 35 evaluable and analyzable patients were included, of whom 30 were women (86%), and the median (range) age was 61 (32-73) years. The most prevalent cancers were breast (18 [51%]), including 15 patients with hormone receptor (HR)-positive/ERBB2-negative and 3 with triple-negative disease, and gynecologic (11 [31%]) cancers. The ORR rate was 28.6% (95% CI, 15%-46%). One patient with endometrioid endometrial adenocarcinoma achieved a CR and remained on therapy at 35.6 months. Patients with confirmed partial response had the following tumor types: 7 had HR-positive/ERBB2-negative breast cancer, 1 had uterine leiomyosarcoma, and 1 had oncocytic parotid gland carcinoma and continued receiving treatment at 28.8 months. Sixteen patients (46%) had stable disease as the best response, 2 (6%) had progressive disease, and 7 (20%) were not evaluable. With a median follow-up of 28.4 months, the overall 6-month PFS rate was 50% (95% CI, 35%-71%). Capivasertib was discontinued because of adverse events in 11 of 35 patients (31%). Grade 3 treatment-related adverse events included hyperglycemia (8 [23%]) and rash (4 [11%]). One grade 4 hyperglycemic adverse event was reported. Conclusions and Relevance This nonrandomized trial found that, in patients with an AKT1 E17K-mutated tumor treated with capivasertib, a clinically significant ORR was achieved, including 1 CR. Clinically meaningful activity with single-agent capivasertib was demonstrated in refractory malignant neoplasms, including rare cancers. Trial Registration ClinicalTrials.gov Identifier: NCT00700882.

Abstract
PURPOSE Immunoprofiling to identify biomarkers and integration with clinical trial outcomes are critical to improving immunotherapy approaches for patients with cancer. However, the translational potential of individual studies is often limited by small sample size of trials and the complexity of immuno-oncology biomarkers. Variability in assay performance further limits comparison and interpretation of data across studies and laboratories. EXPERIMENTAL DESIGN To enable a systematic approach to biomarker identification and correlation with clinical outcome across trials, the Cancer Immune Monitoring and Analysis Centers and Cancer Immunologic Data Commons (CIMAC-CIDC) Network was established through support of the Cancer MoonshotSM Initiative of the National Cancer Institute (NCI) and the Partnership for Accelerating Cancer Therapies (PACT) with industry partners via the Foundation for the NIH. RESULTS The CIMAC-CIDC Network is composed of four academic centers with multidisciplinary expertise in cancer immunotherapy that perform validated and harmonized assays for immunoprofiling and conduct correlative analyses. A data coordinating center (CIDC) provides the computational expertise and informatics platforms for the storage, integration, and analysis of biomarker and clinical data. CONCLUSIONS This overview highlights strategies for assay harmonization to enable cross-trial and cross-site data analysis and describes key elements for establishing a network to enhance immuno-oncology biomarker development. These include an operational infrastructure, validation and harmonization of core immunoprofiling assays, platforms for data ingestion and integration, and access to specimens from clinical trials. Published in the same volume are reports of harmonization for core analyses: whole-exome sequencing, RNA sequencing, cytometry by time of flight, and IHC/immunofluorescence.

Abstract
Therapeutically actionable molecular alterations are widely distributed across cancer types. The National Cancer Institute Molecular Analysis for Therapy Choice (NCI-MATCH) trial was designed to evaluate targeted therapy antitumor activity in underexplored cancer types. Tumor biopsy specimens were analyzed centrally with next-generation sequencing (NGS) in a master screening protocol. Patients with a tumor molecular alteration addressed by a targeted treatment lacking established efficacy in that tumor type were assigned to 1 of 30 treatments in parallel, single-arm, phase II subprotocols.

Abstract
Abstract
Background: NRAS-mutations are established oncologic drivers in many malignancies with no effective targeted therapy options. Preclinical and clinical data have suggested that downstream inhibition with a MEK inhibitor, such as binimetinib, might be efficacious for NRAS-mutated cancers. Methods: Patients who enrolled in the multicenter NCI-MATCH trial master protocol underwent tumor biopsy and molecular profiling by targeted next generation sequencing with a custom Oncomine AmpliSeq™ panel. Patients with refractory solid tumors harboring codon 12, 13, or 61 NRAS-mutations were enrolled in subprotocol Z1A, a single arm study of binimetinib 45 mg twice daily. Patients with melanoma were excluded. The primary endpoint was objective response rate (ORR). Secondary endpoints included progression-free survival (PFS) and overall survival (OS). A post-hoc analysis examined association of NRAS-mutation allele with outcome and histology. Results: 47 eligible patients with refractory solid tumors harboring codon 12, 13, or 61 NRAS-mutations were treated on this trial. The most common cancer types enrolled on this subprotocol were colorectal adenocarcinoma (24/47, 51%), cholangiocarcinoma (7/47, 15%), low-grade papillary serous carcinoma of the ovary (3/47, 6%), and endometrioid endometrial adenocarcinoma patients (3/47, 6%). Observed toxicity was moderate, similar to previous reports, and 27.7% (13 of 47) of eligible patients discontinued binimetinib because of adverse events. The ORR was 2.1% (1 of 47 patients), and the median PFS was 3.5 months. The sole confirmed partial response (PR) was observed in a codon 61 NRAS-mutated indolent malignant ameloblastoma. One patient with a colorectal cancer harboring a NRAS codon 61 mutation had an unconfirmed PR, and two others with NRAS codon 61 mutated colorectal cancer had stable disease for at least 12 months. In a post-hoc analysis, patients with cancers bearing a codon 61 NRAS-mutation (n=22) had a significantly longer OS (p=0.04) and PFS (p=0.006) than those with tumors harboring codon 12 or 13 NRAS-mutations (n=25). Similarly, colorectal cancer patients with NRAS codon 61 mutations treated with binimetinib (n=8) had a significantly longer OS (p=0.03) and PFS (p=0.007) than those with NRAS codon 12 or 13 mutated (n=16) tumors. Conclusions: Single-agent binimetinib did not demonstrate promising efficacy in NRAS-mutated solid tumors. Further studies are needed to clarify whether the increased OS and PFS observed in codon 61 NRAS-mutated cancers reflects a more favorable prognosis for this subtype.

Abstract
PURPOSE BRAFV600 mutations are commonly found in melanoma and thyroid cancers and to a lesser degree in other tumor types. Subprotocol H (EAY131-H) of the NCI-MATCH platform trial sought to investigate the selective BRAF inhibitor dabrafenib and the MEK1/2 inhibitor trametinib in patients with solid tumors, lymphomas, or multiple myeloma whose tumors harbored a BRAFV600 mutation. PATIENTS AND METHODS EAY131-H is an open-label, single-arm study. Patients with melanoma, thyroid, or colorectal cancer were excluded; patients with non-small-cell lung cancer were later excluded in an amendment. Patients received dabrafenib 150 mg twice per day and trametinib 2 mg per day continuously until disease progression or intolerable toxicity. The primary end point was centrally assessed objective response rate (ORR); secondary end points included progression-free survival (PFS), 6-month PFS, and overall survival. RESULTS Thirty-five patients were enrolled, and 29 were included in the primary efficacy analysis as prespecified in the protocol. Median age was 59 years, and 45% of the patients had received ≥ 3 lines of therapy. The confirmed ORR was 38% (90% CI, 22.9% to 54.9%) with P < .0001 against a null rate of 5%, and PFS was 11.4 months (90% CI, 8.4 to 16.3 months); responses were seen in 7 distinct tumor types. Seven patients had a duration of response of > 12 months, including 4 patients with a duration of response of > 24 months. An additional 8 patients had a PFS > 6 months. The median overall survival was 28.6 months. Reported adverse events were comparable to those noted in previously reported profiles of dabrafenib and trametinib. CONCLUSION This study met its primary end point, with an ORR of 38% (P < .0001) in this mixed histology, pretreated cohort. This promising activity warrants additional investigations in BRAFV600-mutated tumors outside of currently approved indications.

Abstract
BACKGROUND Reference values for cardiac magnetic resonance imaging (cMRI) in children and young adults are scarce. This leads to risk stratification of patients with congenital heart diseases being based on volumes indexed to body surface area (BSA). We aimed to produce cMRI Z score equations for ventricular volumes in children and young adults and to test whether indexing to BSA resulted in an incorrect assessment of ventricular dilation according to sex, body composition, and growth. METHODS We retrospectively included 372 subjects aged < 26 years with either normal hearts or conditions with no impact on ventricular volumes (reference group), and 205 subjects with repaired tetralogy of Fallot (TOF) aged < 26 years. We generated Z score equations by means of multivariable regression modelling. Right ventricular dilation was assessed with the use of Z scores and compared with indexing to BSA in TOF subjects. RESULTS Ventricular volume Z scores were independent from age, sex, and anthropometric measurements, although volumes indexed to BSA showed significant residual association with sex and body size. In TOF subjects, indexing overestimated dilation in growing children and underestimated dilation in female compared with male subjects, and in overweight compared with lean subjects. CONCLUSIONS Indexed ventricular volumes measured with cMRI did not completely adjust for body size and resulted in a differential error in the assessment of ventricular dilation according to sex and body size. Our proposed Z score equations solved this problem. Future studies should evaluate if ventricular volumes expressed as Z scores have a better prognostic value than volumes indexed to BSA.

Abstract
PURPOSE NCI-MATCH is a nationwide, histology-agnostic, signal-finding, molecular profile-driven trial for patients with refractory cancers, lymphomas, or myelomas. Patients with tumors harboring actionable aberration(s) in fibroblast growth factor receptor (FGFR) 1-3 were treated with AZD4547, an oral FGFR1-3 inhibitor. METHODS Patients' tumors were screened by next-generation sequencing for predefined FGFR amplification, activating mutations, or fusions. Patients were treated with AZD4547, 80 mg orally twice daily until progression of disease or drug intolerance. A response rate of 16% was considered promising. RESULTS Between July 2016 and June 2017, 70 patients were assigned and 48 received protocol therapy and are eligible for analysis. Patients' tumors harbored FGFR1 or FGFR2 amplification (n = 20), FGFR2 or FGFR3 single-nucleotide variants (n = 19), or FGFR1 or FGFR3 fusions (n = 9). The most common primary tumors were breast (33.3%), urothelial (12.5%), and cervical cancer (10.4%).Grade 3 adverse events were consistent with those described in previous clinical trials. Confirmed partial responses were seen in 8% (90% CI, 3% to 18%) and were observed only in patients whose tumors harbored FGFR1-3 point mutations or fusions. Stable disease was observed in 37.5% (90% CI, 25.8% to 50.4%). The median progression-free survival (PFS) was 3.4 months, and the 6-month PFS rate was 15% (90% CI, 8% to 31%). For patients with tumors harboring FGFR fusions, the response rate was 22% (90% CI, 4.1% to 55%), and 6-month PFS rate was 56% (90% CI, 31% to 100%). CONCLUSION Preliminary signals of activity appeared to be limited to cancers harboring FGFR activating mutations and fusions, although AZD4547 did not meet the primary end point. Different FGFR somatic alterations may confer different levels of signaling potency and/or oncogene dependence.

Abstract
PURPOSE Substantial preclinical evidence and case reports suggest that MEK inhibition is an active approach in tumors with BRAF mutations outside the V600 locus, and in BRAF fusions. Thus, Subprotocol R of the NCI-MATCH study tested the MEK inhibitor trametinib in this population. PATIENTS AND METHODS The NCI-MATCH study performed genomic profiling on tumor samples from patients with solid tumors and lymphomas progressing on standard therapies or with no standard treatments. Patients with prespecified fusions and non-V600 mutations in BRAF were assigned to Subprotocol R using the NCI-MATCHBOX algorithm. The primary endpoint was objective response rate (ORR). RESULTS Among 50 patients assigned, 32 were eligible and received therapy with trametinib. Of these, 1 had a BRAF fusion and 31 had BRAF mutations (13 and 19 with class 2 and 3 mutations, respectively). There were no complete responses; 1 patient (3%) had a confirmed partial response (patient with breast ductal adenocarcinoma with BRAF G469E mutation) and 10 patients had stable disease as best response (clinical benefit rate 34%). Median progression-free survival (PFS) was 1.8 months, and median overall survival was 5.7 months. Exploratory subgroup analyses showed that patients with colorectal adenocarcinoma (n = 8) had particularly poor PFS. No new toxicity signals were identified. CONCLUSIONS Trametinib did not show promising clinical activity in patients with tumors harboring non-V600 BRAF mutations, and the subprotocol did not meet its primary endpoint.

Abstract
Abstract
Background: Over the last 30 years, adolescent and young adult (AYA, 15-39 years of age) patients (pts) with cancer have experienced smaller improvements in 5-year survival compared to younger and older pts. One reason is their historically lower rate of participation in clinical trials (~3% AYA vs. 10% in pts > 40 years of age in adult cancer centers). A histology-agnostic trial provides greater opportunity for the AYA population and may improve accrual. The National Cancer Institute-Molecular Analysis for Therapy Choice (NCI-MATCH; NCT0246506), a phase II precision medicine trial evaluating targeted therapy in adult pts (3 18 years old) based on molecular abnormalities in a tumor-agnostic fashion, has been open since 2015. Jointly developed and coordinated by NCI and ECOG-ACRIN and open through the NCI National Clinical Trials Network and the NCI Community Oncology Research Program at more than 1100 academic and community sites, this trial screened 6801 pts for 39 independently-accruing targeted treatment subprotocols. We reviewed the AYA data from the NCI-MATCH trial, which, due to eligibility criteria, does not include pts age 15-17. Materials and Methods: AYA pts age 18-39 with treatment-refractory malignancies (solid tumor, lymphoma, or myeloma) who were (a) eligible for a screening biopsy on the NCI-MATCH trial (screening cohort [SC]) or (b) had an actionable mutation previously identified through clinically indicated sequencing at a CLIA-approved and NCI-MATCH–accepted laboratory (outside assay cohort [OAC]) were eligible for MATCH AYA analysis. Results: Of the 6801 pts screened for NCI-MATCH, 373 were AYA pts age 18-39 (5.5%). Within the SC, 93.5% (300/321) of AYA pts were successfully biopsied, vs. 92.9% of those age 40+ (5240/5640); 35.7% of the SC AYA vs. 39.6% of the 40+ pts had a study-eligible actionable mutation, and 17% (51/300) of AYA pts vs. 17.8% (934/5240) of those 40+ were subsequently assigned to treatment. Of the 401 pts in the OAC, 30 (7.1%) were AYA; 24/30 (80.0%) of AYA OAC pts were assigned to treatment vs. 87.6% (332/379) of OAC pts age 40+. Screening enrollment data show that at Lead Academic Participating Sites (LAPS), a higher percentage of AYA pts were enrolled compared to pts age 40+ (32.8% [113/344] vs. 24.3% [1472/6047], respectively). In contrast, at NCORP sites, a higher percentage of 40+ pts was enrolled relative to AYA pts (43.8% [2647/6047] vs. 35.8% [123/344], respectively). Among the top histologies enrolled (aside from colon, breast, ovarian) were soft tissue sarcoma other than rhabdomyosarcoma, primary CNS tumors, and liver and hepatobiliary, cervical, and neuroendocrine cancers. Conclusions: There were no statistically significant differences between AYA and older (40+) pts in the number who underwent successful biopsies, the prevalence of tumor actionable mutations, or the number of pts assigned to or who received study treatment. AYA pts were more likely to have been enrolled at a LAPS than a NCORP site, consistent with the AYA population being referred to LAPS upon progression from first-line treatment. Enrollment of the AYA in adult cancer centers in the NCI-MATCH trial was higher than the historical 3%: 5.5% in the SC and 7.1% in the OAC. As more tissue-agnostic studies become available in nationwide trials, AYA participation in clinical trials may increase.

Abstract
Abstract
Introduction: NCI-MATCH, developed by ECOG-ACRIN & NCI, is the largest precision medicine study for pts with refractory malignancy. Over 1100 clinical sites in the National Clinical Trials Network enrolled pts. The purpose of the study is to identify potentially beneficial targeted treatments across tumor types with similar molecular abnormalities. Methods: The NCI Central IRB approved NCI-MATCH. Pts with refractory/no treatment available solid tumors, lymphomas or myelomas had a fresh biopsy profiled by next generation sequencing (143 genes, > 4000 single nucleotide variants, indels, amplifications & targeted fusions). Pts are assigned by a defined algorithm to treatments with evidence of activity against tumors with the relevant molecular alteration. Pts are excluded if a treatment is FDA approved or known to be ineffective for their malignancy. After successfully sequencing fresh biopsies from 5540 pts, subprotocols with extremely rare variants lacked sufficient accrual. To address actionable variants with a prevalence of < 1.5%, we decided to accept clinical sequencing results from 30 commercial and academic laboratories vetted by NCI-MATCH to address relevant variants. These labs notify clinicians participating in NCI-MATCH if their pt’s tumor contains an actionable variant. Treatment continues until tumors became refractory, pt intolerance or withdrawal of consent. An objective response rate (ORR by RECIST) of > 16% among 31 eligible patients is considered a positive signal. Results: After screening 5540 pts, 37.6% had an actionable variant. After histology and treatment-specific exclusions, 17.8% were assigned and 69.5% enrolled on the assigned subprotocol. 11 of the initial 30 subprotocols reached completion with adequate follow-up. Of the first 11 evaluable subprotocols, 3 addressing rare variants had a positive signal: Nivolumab in pts with loss of expression of MLH1 or MSH2 (ORR 36%), capivasertib in pts with AKT mutations (ORR 23%), and dabrafenib + trametinib in pts with BRAF V600 mutations (ORR 33%). These molecular variants were found in 2%, 1.2% and 1.9% respectively, of screened pts. Two other subprotcocols (afatinib in ERBB2 mutations and AZD4547 in FGFR abnormalities) showed responses in rare tumors or specific variant subsets, respectively. As of July 15, 2019, an additional 378 of 432 (88%) pts have been assigned to a treatment with a clinical sequencing assay; 83% of these pts enrolled to 1 of 24 subprotocols, allowing completion of an additional 9 of the original 30 subprotocols and complete accrual to 2 of 5 recently added subprotocols. Four of 35 subprotocols closed for lack of accrual, 10 continue accruing and 4 are planned. Conclusions: Platform precision medicine trials can identify potentially useful targeted treatments for diverse malignancies in pts with uncommon tumors & rare actionable variants, an unmet need. In a population of pts with refractory cancers, lymphomas and myelomas, 30-40% will have an actionable variant for targeted treatment (investigational or standard). Of the first 11 subprotocols with adequate follow-up, 3 (27%) showed a positive signal and an additional 2 showed responses in rare tumors or in a molecular subset, suggesting that the NCI-MATCH trial approach identifies useful targets for further exploration.

Abstract
BACKGROUND The National Cancer Institute-Molecular Analysis for Therapy Choice (NCI-MATCH) is a national precision medicine study incorporating centralized genomic testing to direct refractory cancer patients to molecularly targeted treatment subprotocols. This treatment subprotocol was designed to screen for potential signals of efficacy of ado-trastuzumab emtansine (T-DM1) in HER2-amplified histologies other than breast and gastroesophageal tumors. METHODS Eligible patients had HER2 amplification at a copy number (CN) >7 based on targeted next-generation sequencing (NGS) with a custom Oncomine AmpliSeq™ (ThermoFisher Scientific) panel. Patients with prior trastuzumab, pertuzumab or T-DM1 treatment were excluded. Patients received T-DM1 at 3.6 mg/kg i.v. every 3 weeks until toxicity or disease progression. Tumor assessments occurred every three cycles. The primary end point was centrally assessed objective response rate (ORR). Exploratory end points included correlating response with HER2 CN by NGS. The impact of co-occurring genomic alterations and PTEN loss by immunohistochemistry were also assessed. RESULTS Thirty-eight patients were enrolled and 36 included in efficacy analysis. Median prior therapies in the metastatic setting was 3 (range 0-9; unknown in one patient). Median HER2 CN was 17 (range 7-139). Partial responses were observed in two (5.6%) patients: one mucoepidermoid carcinoma of parotid gland and one parotid gland squamous cell cancer. Seventeen patients (47%) had stable disease including 8/10 (80%) with ovarian and uterine carcinomas, with median duration of 4.6 months. The 6-month progression-free survival rate was 23.6% [90% confidence interval 14.2% to 39.2%]. Common toxicities included fatigue, anemia, fever and thrombocytopenia with no new safety signals. There was a trend for tumor shrinkage with higher levels of gene CN as determined by the NGS assay. CONCLUSION T-DM1 was well tolerated. While this subprotocol did not meet the primary end point for ORR in this heavily pre-treated diverse patient population, clinical activity was seen in salivary gland tumors warranting further study in this tumor type in dedicated trials.

Abstract
OBJECTIVE There is a rising incidence of diabetes worldwide; however there seems to be a higher incidence and prevalence rates in the Arab world when compared with the global average. 1 Out of the top 10 countries with the highest prevalence rates, six are Arab countries and almost 20.5 million people in that part of the world live with diabetes. Despite this, published scientific research from the 22 Arab countries is limited and seems to be of lower quality when compared with the rest of the developed world. 2 Therefore, our aim was to explore the contribution of the different Arab countries in the world literature, to identify the diabetic foot ulcer (DFU) prevalence and incidence rates and to quality appraise these studies. METHOD A systematic review, following PRISMA guidelines, was undertaken to identify the incidence and prevalence of DFUs in the Arab world. The following databases were searched: PubMed, Embase CINAHL, Web of Science (Scopus), Global Health and EBSCO Results: A total of nine papers were identified. The mean prevalence of DFU in Saudi Arabia was 11.85% (4.7-19%), in Egypt was 4.2% (1-7.4%), in Jordan was 4.65% (4-5.3%), in Bahrain was 5.9% and in Iraq was 2.7%. A single study identified DFU incidence in Saudi Arabia as 1.8% between 2009-2010. CONCLUSION The mean prevalence rates of DFU were highest in Saudi Arabia and Bahrain and lowest in Iraq. Saudi Arabia had the only reported incidence study, thus findings could not be compared to other countries of the Arab world. There were no studies identified during our search reporting prevalence rates of DFU in 17 of the 22 Arab countries. It is clear that further research is required to determine the incidence and prevalance of DFUs in the Arab world and that progress is needed in order to improve the quality of research conducted in those countries.

Abstract
3002 Background: The NCI-MATCH precision medicine trial assigns patients (pts) with solid tumors, lymphomas, or multiple myeloma with progression on prior treatment to a targeted therapy based on genetic alterations identified in pre-treatment biopsies. Arm H (EAY131-H) evaluated the combination of the BRAF inhibitor (inh) dabrafenib (DAB), and the MEK inh, trametinib (TRM), in pts with BRAF V600E/K mutations. Methods: Pts with melanoma, thyroid, or colorectal cancer were excluded. Pts with NSCLC were excluded after the U.S. Food and Drug Administration (FDA) approved DAB/TRM for this indication. Pts received DAB 150 mg po BID and TRM 2 mg PO daily on 28 day cycles until disease progression or intolerable toxicity; restaging was performed every 2 cycles. The primary endpoint was objective response rate (ORR); secondary endpoints included progression-free survival (PFS), 6-month PFS, and overall survival (OS). Results: A total of 35 pts were enrolled from 1/2016-2/2018; 2 were ineligible (CrCl below criteria; labs out of window). Over 17 distinct tumor histologies were represented. 58% of pts were female, median age was 63 (range 21-85), 94% were Caucasian, and 48% of pts had received at least 3 prior therapies (range 1- 8). The confirmed ORR was 33.3% (90% CI 19.9%, 49.1%), with a median duration of response (DoR) of 12 months (mon). Varied histologies had a DoR of > 12 mon: histiocytic sarcoma, cholangiocarcinoma and mixed adenoneuroendocrine carcinoma of unknown primary, among others. Median PFS was 9.4 mon; the 6 mon PFS rate was 70.6% (90% CI 58.2%-85.5%), and an additional 10 pts had a PFS > 5.5 mon. Median OS has not been reached. At the time of data cutoff (12/2018) 11 pts continue on treatment. Adverse events (AE) were comparable to previously reported profiles of DAB/TRM; no new AEs were identified. The most frequent grade 3 AEs were fatigue, neutropenia, hyponatremia, hypophosphatemia, and urinary tract infection; there was 1 grade 4 sepsis; no grade 5 AEs. Conclusions: In this pre-treated, mixed histology cohort, DAB and TRM showed promising activity outside of currently approved FDA indications warranting further investigations. Correlative analyses are planned. Clinical trial information: NCT02465060.

Abstract
10011 Background: The screening protocol for the NCI-Children’s Oncology Group (COG) Pediatric Molecular Analysis for Therapy Choice (MATCH) trial detects tumor alterations that are used to assign patients with treatment-refractory or recurrent cancers to phase 2 treatment arms of molecularly-targeted therapies. Methods: Patients age 1 to 21 years old with treatment-refractory or recurrent solid tumors, non-Hodgkin lymphomas, or histiocytic disorders treated at U.S. based COG sites are eligible. DNA and RNA extracted from FFPE tumor samples are sequenced using an Oncomine cancer gene panel for detection of mutations, amplifications, and fusions. Loss of SMARCB1, SMARCA4, and PTEN expression is detected by immunohistochemistry. Lists of actionable mutations (aMOIs) based upon available clinical and pre-clinical data are used a priori to determine eligibility for treatment arms. Results: Between 7/24/17 and 12/31/18, 422 patients with a median age of 13 years (range 1-21) were enrolled from 93 COG sites. Solid tumors comprised 71% (n = 300) of diagnoses, CNS tumors 24% (n = 101) and lymphomas/histiocytoses 5% (n = 21). A tumor sample was submitted for 390 patients, sequencing was attempted for 370 (95%), and results were confirmed for 357 (92%). Median turn-around time was 15 days. An aMOI for at least one of the 10 current treatment arms was identified in 112 patients (29%, 95% CI 24%-33%); 95 patients (24%, 95% CI 20%-29%) were assigned to a treatment arm with 39 patients (10%, 95% CI 7%-13%) enrolled to date. The aMOI rate was similar in patients less than 12 years of age (35%) compared to patients 12 years and older (25%). Actionable MAPK pathway alterations were found in 11% of patients (n = 41), most often HRAS/ KRAS/ NRAS mutations (n = 16), BRAF mutations or fusions (n = 14), or NF1 mutations (n = 11). Other genes with recurrent aMOIs included SMARCB1 (n = 14), ALK (n = 8), CDK4 (n = 8), PIK3CA (n = 7), PTEN (n = 7), FGFR1 (n = 5), and BRCA1/BRCA2 (n = 5). Conclusions: Approximately one-quarter of patients with tumor submitted for Pediatric MATCH screening have been assigned to an investigational therapy, facilitating the evaluation of molecularly-targeted agents in biomarker-positive pediatric cohorts through a collaborative nationwide study. Clinical trial information: NCT03155620.

Abstract
3016 Background: NCI-MATCH is a precision medicine trial that assigns treatment to refractory cancer patients by tumor mutation profile rather than by histology. After screening fresh tumor biopsies from nearly 6000 patients many treatment arms did not meet accrual due to the low prevalence of the eligible variants. NCI MATCH developed an approach to identify patients for the remaining arms utilizing a network of academic and commercial CLIA-certified labs that perform NGS assays as routine care at MATCH participating sites. Methods: Candidate labs were recruited through a notice in the Federal Register and posted on the NCI and ECOG ACRIN web sites. Twenty-seven labs (17 academic/10 commercial) submitted applications. After acceptance each lab analyzed a common set of 10 DNAs extracted from 8 cell lines and 2 clinical samples for concordance with the central NCI-MATCH NGS assay. Results: For the 17 labs with concordance results, a median of 8 (range 2 – 58) copy number variants (CNVs) were evaluated by the NGS assay of each DL, with the number evaluated depending on each lab’s clinical assay panel content. CNV concordance between central and DL assays, as measured by positive percent agreement (PPA), averaged 98.7% (range 87.5% - 100%) with the central assay as referent and 94.1% (range 77.8% – 100%) with the DL assay as referent. For single nucleotide variants (SNVs) and Insertion/deletions (Indels) combined, a median of 19 variants (range 11 – 26) were evaluated by each DL for concordance. PPA between central and DL assays averaged 98.0% (range 87.5% – 100%) and 98.6% (range 90.0% – 100%) with central and DL assay as referents, respectively. Strong correlations were observed between central and DL assays for both CNVs (median r = 0.93; 0.33 – 1.00) and SNV/Indels (median r = 0.98; 0.67 – 0.99). Conclusions: Our results suggest that different NGS assay platforms using diverse strategies for target enrichment and data analysis may still achieve high concordance if pre-analytical variables are minimized and the common genomic regions interrogated by each assay are well-understood. The designated lab network allows for a wider search for rare variants in tumors and provides a model for conducting future clinical trials. Clinical trial information: NCT02465060.

Abstract
BACKGROUND Nursing assessment of elderly patients is imperative in Emergency Departments (ED) while providing interventions that increase independence facilitating discharge to primary healthcare. AIMS To systematically review the impact of geriatric focused nurse assessment and intervention in the ED on hospital utilisation in terms of admission rate, ED revisits and length of hospital stay (LOHS). METHODS Search strategy used following databases; Cochrane, Medline, CINAHL, Embase, Scopus and Web of Knowledge; And terms; geriatric nurse assessment, nurse discharge planning, geriatric nurse specialist, nurse intervention, emergency department, accident and emergency, patient outcomes, discharge, admissions, readmissions, hospital utilization, hospitalization, length of stay/hospital stay. RESULTS Nine studies were included: seven RCTs and two prospective pre/post-intervention designed studies. Geriatric focused nursing assessment and interventions did not have a statistical impact on hospitalization, readmissions, LOHS and ED revisits. Risk screening and comprehensive geriatric assessment extending into primary care may reduce readmission rates but not affect hospitalization. An increase in ED visits in the intervention group at 30 days post-intervention was noted. CONCLUSION Inconsistencies in assessment and interventions for the older person in ED are apparent. Further research evaluating a standardised risk assessment tool and innovative interventions extending into primary healthcare is required.

Abstract
Abstract
Purpose: NCI-Molecular Analysis for Therapy Choice (NCI-MATCH/EAY131), by ECOG-ACRIN (EA) and NCI, is the first national signal-finding trial to incorporate centralized NGS testing to direct patients (pts) to molecularly targeted parallel phase 2 treatment arms. We report status of accrual from opening on 08/12/15 thru 07/16/17 and future plans.
Methods: Eligible pts have advanced/refractory solid tumors, lymphoma, or myeloma. Drug treatments and molecular targets require stringent levels of evidence (LOE). Each arm (N-35) has a phase 2 dose, a molecular abnormality believed to predict response, and evidence of clinical activity. Pts must have enrolled by 05/22/17 with intent to submit fresh tissue or recent clinical biopsy. Tumor cores are shipped to the EA Central Biorepository & Pathology Facility at MD Anderson Cancer Center for evaluation of histopathology and % tumor; PTEN, MLH1, and MSH2 IHC; and RNA/DNA extraction. NGS is performed in one of 4 CLIA-accredited laboratories using the NCI-MATCH adapted Oncomine™ panel (Version 1.0; 143 genes with >4000 reported variants including SNVs, indels, amplifications, and gene fusions). When an actionable mutation of interest (aMOI) or relevant IHC result is identified, the pt is assigned to treatment by a custom-designed informatics system (MATCHbox). If >1 aMOI present, the pt is assigned by the variant with the highest LOE.
Results: As of 07/16/17, 5963 tumors were screened for 30 treatment arms. The assay success rate is 93%; median turnaround is 15 days (from sample receipt to return of results). 38.2% of pts have common cancers: colorectum (15.4%), breast (12.8%), lung (7.4%), and prostate (2.6%); 61.8% have less common tumors. The current overall match rate to aMOI’s is 18% (95% CI 17%, 19%); aMOI prevalence rates range from 3.47% to zero. The match rate also varies across tumor types: <10% in pancreatic & SCLC; >30% in bladder/urinary tract, uterine, and head/neck cancer. 998 pts have been assigned to Rx; 69% have enrolled. Of 30 arms, 8 have enrolled ≥ 35 pts; some arms with higher prevalence rates have been expanded to N=70 to accommodate pts with matching aMOIs. Arms with less frequent aMOIs will not complete accrual within the 6,000-pt central screening goal, leading to identification of pts for screening based on approved high-volume NGS labs’ assay results, verified centrally.
Conclusions: NCI-MATCH screened ~6000 pts at a rate that far exceeded expectations, and with acceptable toxicity; NGS was successful in 93%, well above the industry average of ~80%. The pace of enrollment, along with the trial’s availability at 1100+ sites, reflects the broad interest in the promise of genomics and the ability of such a trial to deliver on that promise. Lower accrual to "rare variant" arms led to use of high-volume NGS laboratories to complete the study. Follow-up will determine whether matching drugs to molecular targets results in meaningful response rates and improved patient outcome.

Abstract
OBJECTIVE Diabetic foot ulcers (DFUs) are a significant challenge in wound care practice. Our aim was to evaluate the combined use of of two therapies, ultrasound and electrostimulation, in the treatment of DFUs. METHOD This study employed a prospective, non-comparative, case series design, undertaken in a podiatry-led diabetic foot clinic, in an acute hospital setting, in an urban location in Ireland. We recruited patinets with hard-to-heal DFUs who were treated twice a week with combined modulated ultrasound and electric current stimulation. RESULTS We recruited seven patients with eight chronic DFUs. A mean wound size reduction of 71% was achieved and there were no adverse reactions to the therapy. CONCLUSION The results of this small case series indicate that combined modulated ultrasound and electric current stimulation offers promise as an adjunct therapy for DFUs. Further large scale trials are now warranted.

Abstract
OBJECTIVE Our aims were to: establish the clinical significance of ultrasound, thermography, photography and subepidermal moisture (SEM) measurement; determine the accuracy of ultrasound, thermography, photography and SEM measurement in detecting skin/tissue damage; determine the relative accuracy of one of these assessment methods over another; make recommendations for practice pertaining to assessment of early skin/tissue damage. METHOD The following databases, Cochrane Wounds Group Specialised Register, The Cochrane Central Register of Controlled Trials, Ovid MEDLINE, Ovid EMBASE, Elsevier version, EBSCO CINAHL, ClinicalTrials.gov , WHO International Clinical Trials Registry (ICTR) and The EU Clinical Trials Register were searched for terms including; thermography, ultrasound, subepidermal moisture, photograph and pressure ulcer. RESULTS We identified four SEM, one thermography and five ultrasound studies for inclusion in this review. Data analysis indicated that photography was not a method which allowed for the early prediction of PU presence. SEM values increased with increasing tissue damage, with the sacrum and the heels being the most common anatomical locations for the development of erythema and stage I PUs. Thermography identified temperature changes in tissues and skin that may give an indication of early PU development; however the data were not sufficiently robust. Ultrasound detected pockets of fluid/oedema at different levels of the skin that were comparable with tissue damage. Thus, SEM and ultrasound were the best methods for allowing a more accurate assessment of early skin/tissue damage. Using the EBL Critical Appraisal Tool the overall validities of the studies varied between 33.3-55.6%, meaning that there is potential for bias within all the included studies. All of the studies were situated at level IV, V and VII of the evidence pyramid. Although the methodological quality of the studies warrants consideration, these studies showed the potential that SEM and ultrasound have in early PU detection. CONCLUSION SEM and ultrasound are promising in the detection and prediction of early tissue damage and PU presence. However, these methods should be further studied to clarify their potential for use more widely in PU prevention strategies.

Abstract
Background Globally the older population is increasing rapidly. As a result there is an increase in frail older persons living within the community, with increased risks of a hospital admission and higher mortality and morbidity rates. Due to complexity of care, health care professionals face challenges in providing effective case management and avoiding unplanned admissions to hospital. A community virtual ward (CVW) model was developed to assist health care professionals to support older persons at home during periods of illness and/or functional decline. Methods A quantitative observational study was conducted to examine if a CVW model of care reduced unplanned hospital admissions and emergency department (ED) presentations in 54 patients over a 12-month period. The sign-rank test examined matched data on bed days, ED presentations, and unplanned hospital admissions pre- and post-CVW implementation. Other risk factors for admission to hospital were examined using the Mann–Whitney test pre-and post-CVW admission, including falls, living alone, and cognition. Correlations between hospital admission avoidances and unplanned hospital admissions and ED presentations were tested using Spearman’s ρ test. Results There was a reduction in ED presentations post-CVW admission (P<0.001), and median unscheduled admissions were reduced (P=0.001). Those living alone had a lower number of ED presentations (median 0.5, interquartile range 0–1) prior to admission in comparison to those living with a caregiver, with no differences observed during admission to CVW. For those who experienced a fall during CVW admission, the odds ratio (OR) of requiring long-term care doubled for each extra fall (OR =2.24, 95% CI 1.11 to 4.52, P=0.025). Reduced cognition was associated with an increased risk of ED presentations (ρ=0.292, P<0.05) but not associated with increased risks of unplanned hospital admissions (ρ=0.09, P=0.546). There were no significant correlations seen between admission avoidance and the number of unplanned hospital admissions or ED presentations. Conclusion Through an integrated approach to care, a CVW model in the care of older persons can reduce ED presentations and unplanned hospital admissions.

Abstract
Lettuce seedlings are attracting interest in the computing world due to their capacity to become hybrid circuit components, more specifically, in the creation of living 'wires'. Previous studies have shown that seedlings can be hybridised with gold nanoparticles and withstand mild electrical currents. In this study, lettuce seedlings were hybridised with a variety of metallic and non-metallic nanomaterials: carbon nanotubes, graphene oxide, aluminium oxide and calcium phosphate. Toxic effects and the following electrical properties were monitored: mean potential, resistance and capacitance. Macroscopic observations revealed only slight deleterious health effects after administration with one variety of particle, aluminium oxide. Mean potential in calcium phosphate-hybridised seedlings showed a considerable increase when compared with the control, whereas those administered with graphene oxide showed a small decrease; there were no notable variations across the remaining treatments. Electrical resistance decreased substantially in graphene oxide-treated seedlings whereas slight increases were shown following calcium phosphate and carbon nanotubes applications. Capacitance showed no considerable variation across treated seedlings. These results demonstrate that use of some nanomaterials, specifically graphene oxide and calcium phosphate, may be towards biohybridisation purposes including the generation of living 'wires'.

Abstract
Purpose: Angioscopy for in situ vein graft preparation has been criticized on the basis that the trauma of instrumentation may predispose to accelerated intimal hyperplasia, jeopardizing patency rates following infrainguinal revascularization. The aim of this study was to assess the effects of angioscopic preparation on endothelial integrity and smooth muscle cell (SMC) behavior in an established organ culture model of human saphenous vein (HSV). Methods: HSV was harvested from 12 patients during bypass surgery before and after angioscopic preparation. Endothelial integrity was evaluated by immunohistochemical staining with JC-70 and scanning electron microscopy (SEM); remaining segments of pre-and postangioscopy vein were maintained in culture for 14 days in medium supplemented with 30% fetal calf serum. Viability was confirmed by measurement of tissue adenosine triphosphate on day 14 and thickness of the neointima was measured by computerized image analysis of histologic sections. Monoclonal antibodies to proliferating cell nuclear antigen (PCNA) were used as an immunohistochemical marker for proliferating SMCs. Results: There was a significant reduction in the percentage staining by JC-70 (71.3% versus 20.4%) in pre- versus postangioscopy vein (p = 0.002 by Wilcoxon's rank test; n = 12). This was supported by SEM images. Despite this, there were no significant differences between the pre- and postangioscopy HSVs after 14 days of culture with respect to neointimal thickness (61 versus 56 μm) and staining with PCNA (4.80 versus 4.08 nuclei per 10 (μm), all according to Wilcoxon's rank test. Conclusions: Angioscopic vein graft preparation is associated with endothelial cell loss but does not induce additional neointimal hyperplasia in HSV in vitro. These results suggest that angioscopic manipulation does not alter SMC behavior.

Abstract
It is estimated that over 200 million adults worldwide have osteoporosis, a disease that has increasing socioeconomic impact reflected by unsustainable costs associated with disability, fracture management, hospital stays, and treatment. Existing therapeutic treatments for osteoporosis are associated with a variety of issues relating to use, clinical predictability, and health risks. Consequently, additional novel therapeutic targets are increasingly sought. A promising therapeutic candidate is sclerostin, a Wnt pathway antagonist and, as such, a negative regulator of bone formation. Sclerostin antibody treatment has demonstrated efficacy and superiority compared to other anabolic treatments for increasing bone formation in both preclinical and clinical settings. Accordingly, it has been suggested that sclerostin antibody treatment is set to achieve market approval by 2017 and aggressively compete as the gold standard for osteoporotic treatment by 2021. In anticipation of phase III trial results which may potentially signify a significant step in achieving market approval here, we review the preclinical and clinical emergence of sclerostin antibody therapies for both osteoporosis and alternative applications. Potential clinical challenges are also explored as well as ongoing developments that may impact on the eventual clinical application of sclerostin antibodies as an effective treatment of osteoporosis.
