Background The epidemiological transition of non-communicable diseases replacing infectious diseases as the main contributors to disease burden has been well documented in global health literature. Less focus, however, has been given to the relationship between sociodemographic changes and injury. The aim of this study was to examine the association between disability-adjusted life years (DALYs) from injury for 195 countries and territories at different levels along the development spectrum between 1990 and 2017 based on the Global Burden of Disease (GBD) 2017 estimates. Methods Injury mortality was estimated using the GBD mortality database, corrections for garbage coding and CODEm—the cause of death ensemble modelling tool. Morbidity estimation was based on surveys and inpatient and outpatient data sets for 30 cause-of-injury with 47 nature-of-injury categories each. The Socio-demographic Index (SDI) is a composite indicator that includes lagged income per capita, average educational attainment over age 15 years and total fertility rate. Results For many causes of injury, age-standardised DALY rates declined with increasing SDI, although road injury, interpersonal violence and self-harm did not follow this pattern. Particularly for self-harm opposing patterns were observed in regions with similar SDI levels. For road injuries, this effect was less pronounced. Conclusions The overall global pattern is that of declining injury burden with increasing SDI. However, not all injuries follow this pattern, which suggests multiple underlying mechanisms influencing injury DALYs. There is a need for a detailed understanding of these patterns to help to inform national and global efforts to address injury-related health outcomes across the development spectrum.

AbstractBackgroundSeveral registry-based analyses suggested a survival advantage for married versus single patients with pancreatic cancer. The mechanisms underlying the association of marital status and survival are likely multiple and complex and, therefore, may be obscured in analyses generated from large population-based databases. The goal of this research was to characterize this potential association of marital status with outcomes in patients with resected pancreatic cancer who underwent combined modality adjuvant therapy on a prospective clinical trial.Materials and MethodsThis is an ancillary analysis of 367 patients with known marital status treated on NRG Oncology/RTOG 97-04. Survival analysis was performed using the Kaplan-Meier method and compared using the log-rank test. Multivariate analysis was performed using the Cox proportional hazards regression model.ResultsOf 367 patients, 271 (74%) were married or partnered and 96 (26%) were single. Married or partnered patients were more likely to be male. There was no association between marital status and overall survival (OS) or disease-free survival (DFS) on univariate (hazard ratio [HR], 1.09 and 1.01, respectively) or multivariate analyses (HR, 1.05 and 0.98, respectively). Married or partnered male patients did not have improved survival compared with female or single patients.ConclusionAncillary analysis of data from NRG Oncology/RTOG 97-04 demonstrated no association between marital and/or partner status and OS or DFS in patients with resected pancreatic cancer who received adjuvant postoperative chemotherapy followed by concurrent external beam radiation therapy and chemotherapy.

PURPOSE The 21-gene recurrence score (RS) assay is prognostic among women with early-stage estrogen receptor–positive (ER+) and human epidermal growth factor receptor 2–negative (HER2−) breast cancer and is used to inform recommendations for chemotherapy. Women ≤ 40 years of age represent a minority of patients studied using gene expression profiles. METHODS The Young Women's Breast Cancer Study is a prospective cohort of women diagnosed with breast cancer at age ≤ 40 years and enrolled patients between 2006 and 2016 (N = 1,302). We identified patients with stage I-III ER+/HER2− breast cancer. The RS assay was performed on banked specimens for patients who had not been tested clinically. Distant recurrence-free survival (DRFS) was assessed by TAILORx and traditional RS risk groups among patients with axillary node–negative (N0) and limited node–positive (N1) breast cancer. RESULTS Among eligible women (N = 577), 189 (33%) had undergone RS testing, and 320 (56%) had banked specimens sufficient for testing. Median follow-up was 6.0 years. Median age at diagnosis was 37.2 years; 300 of 509 patients (59%) had N0 breast cancer, of whom 195 (65%) had an RS of 11-25 and fewer than half (86 of 195; 44%) received chemotherapy. Six-year DRFS rates were 94.4% and 92.3% (RS < 11), 96.9% and 85.2% (RS 11-25), and 85.1% and 71.3% (RS ≥ 26) among women with N0 and N1 disease, respectively. CONCLUSION The RS assay is prognostic among young women with node-negative and limited node-positive breast cancer, representing a valuable tool for risk stratification. Disease outcomes with a median follow-up of 6 years among young women with N0 disease and an RS of 0-25, a minority of whom received chemotherapy, and node-positive disease with an RS < 11 were very good, whereas those with N0 disease and an RS ≥ 26 or N1 disease with an RS ≥ 11 experienced substantial risk of early distant recurrence.

Rationale: GWAS (Genome-Wide Association Studies) have identified hundreds of genetic loci associated with atrial fibrillation (AF). However, these loci explain only a small proportion of AF heritability. Objective: To develop an approach to identify additional AF-related genes by integrating multiple omics data. Methods and Results: Three types of omics data were integrated: (1) summary statistics from the AFGen 2017 GWAS; (2) a whole blood EWAS (Epigenome-Wide Association Study) of AF; and (3) a whole blood TWAS (Transcriptome-Wide Association Study) of AF. The variant-level GWAS results were collapsed into gene-level associations using fast set-based association analysis. The CpG-level EWAS results were also collapsed into gene-level associations by an adapted SNP-set Kernel Association Test approach. Both GWAS and EWAS gene-based associations were then meta-analyzed with TWAS using a fixed-effects model weighted by the sample size of each data set. A tissue-specific network was subsequently constructed using the NetWAS (Network-Wide Association Study). The identified genes were then compared with the AFGen 2018 GWAS that contained more than triple the number of AF cases compared with AFGen 2017 GWAS. We observed that the multiomics approach identified many more relevant AF-related genes than using AFGen 2018 GWAS alone (1931 versus 206 genes). Many of these genes are involved in the development and regulation of heart- and muscle-related biological processes. Moreover, the gene set identified by multiomics approach explained much more AF variance than those identified by GWAS alone (10.4% versus 3.5%). Conclusions: We developed a strategy to integrate multiple omics data to identify AF-related genes. Our integrative approach may be useful to improve the power of traditional GWAS, which might be particularly useful for rare traits and diseases with limited sample size.

PURPOSE: After ASCO and National Comprehensive Cancer Network guideline recommendations for triple antiemetic prophylaxis for carboplatin area under the curve (AUC) ≥ 4, and the publication of studies documenting avoidable acute care after chemotherapy involving nausea and vomiting (NV) and other toxicities, we studied clinician adherence to the guideline change and assessed avoidable acute-care use. METHODS: Using a large electronic health record database, we evaluated antiemetic prophylaxis as recommended in the guidelines and post-chemotherapy avoidable acute-care use (defined as involving any of NV or 8 other toxicities) for patients initiating carboplatin or other chemotherapy from October 2012 to August 2018. RESULTS: We identified 11,554 carboplatin courses. After the guideline change adding neurokinin-1 receptor antagonists (RAs) for carboplatin AUC ≥ 4, its use rose to 20% of courses from the prior average of 16%; virtually all courses also included a 5-HT3 RA plus dexamethasone. We found avoidable acute care in 23% of courses; one quarter of these events were associated with NV. Acute care rates after carboplatin mirrored those after other highly emetogenic chemotherapy or oxaliplatin and exceeded those after other chemotherapy regimens. The > 80% shortfall in adherence may have been caused by low awareness or acceptance of the guideline change and/or by poor awareness of avoidable acute-care use after carboplatin. CONCLUSION: Neurokinin-1 RA prophylaxis for carboplatin AUC ≥ 4 remains low and largely unchanged despite National Comprehensive Cancer Network and ASCO 2017 recommendations for inclusion. NV and avoidable acute care involving NV seen after carboplatin were consistent with other highly emetogenic chemotherapy. Clinician action is required to remediate incomplete prophylaxis and to no longer place patient outcomes, resources for cancer treatment, and clinician reimbursement at risk.

Introduction Genotype-phenotype discordance occurs occasionally in congenital adrenal hyperplasia (CAH). Its causes are largely unknown. We describe a case of monochorionic, diamniotic twins with discordant clinical presentations of CAH, and show evidence for this being due to mosaicism resulting from a postzygotic full gene deletion of CYP21A2 prior to twinning. Case description A 7-day-old 36-week gestation female infant (Twin A) presented to the emergency department with elevated 17-hydroxyprogesterone (17-OHP). Her identical twin (Twin B) had normal 17-OHP on newborn screening. Both twins showed signs of virilization, more pronounced in Twin B. Molecular genetic testing of both twins and their parents showed a WT paternally-inherited CYP21A2 and a maternally-inherited copy containing the c.293-13C>G mutation. Both twins were also found to have a 5′-CYP21A1P/CYP21A2-3′ hybrid (product of the common 30-kb deletion), derived from the deletion of the paternally-inherited CYP21A2. Neither mother nor father carried the deletion. Conclusions The genetic findings are consistent with mosaicism for two CYP21A2 cell lines in both twins. The first cell line is expected, based on parental results, while the second line is due to a postzygotic full gene deletion of the paternally-inherited WT CYP21A2. The resultant genotype, compound heterozygosity for c.293-13C>G and a CYP21A2 full gene deletion, is consistent with a salt-wasting CAH phenotype. Differential distribution of the second cell line between the twins is most likely the cause for their discrepant phenotypes. We believe this is the first report of somatic CYP21A2 mosaicism, and represents a novel cause for discrepant CAH phenotypes in monozygotic twins.

112 Background: In the US, the CMS OP-35 oncology outcome measure deems 30-day post-chemotherapy acute care involving nausea and emesis (NV) or 8 other toxicities as avoidable, with studies showing 15% of > 2500 patients receiving anthracycline + cyclophosphamide (AC)-based chemotherapy had avoidable acute care, of which 32% involved NV. Our aim was to evaluate resource use (emergency department [ED] visits, inpatient admissions [IP], or hydration) in a prospective trial of women with breast cancer who received combination netupitant/palonosetron (NEPA) + dexamethasone (DEX) for CINV prophylaxis for AC-based chemotherapy. Methods: Women initiating AC received oral or IV NEPA + DEX. Pre-specified endpoints included safety, complete response, acute care (ED/IP), unplanned IV hydrations (as determined by investigator), days of CINV, and ≥3 days of CINV. We defined CINV as emesis or rescue drug use up to 5 days after AC, and defined concomitant ED/IP or hydrations in the same period as CINV-related. We limited our analysis to the first 2 cycles, the median duration in the NEPA study. Results: 402 patients received ≥1 cycle of AC and 391 completed 2 cycles. Nine patients had IP (none CINV-related), and 5 patients had a total of 6 ED visits (1 CINV-related). Three patients had a CINV-related unplanned hydration. Patients had ≥1 day of CINV in 172 of 793 cycles (21.7%); of these, the majority had symptom duration for 1-2 days, while 78 (9.8%) had ≥3 days of CINV in a cycle. Conclusions: In this prospective CINV prophylaxis study in women receiving AC chemotherapy, < 1% of women receiving NEPA + DEX required acute care for CINV and < 1% required unplanned hydrations for CINV. These rates are below previously reported CINV-related acute care rates for AC suggesting NEPA may help avoid CINV-related acute care. Clinical trial information: NCT03403712.
