Objective: The goal of the present study was to assess the sound quality of a cochlear implant for single-sided deaf (SSD) patients fit with a cochlear implant (CI). Background: One of the fundamental, unanswered questions in CI research is “what does an implant sound like?” Conventional CI patients must use the memory of a clean signal, often decades old, to judge the sound quality of their CIs. In contrast, SSD-CI patients can rate the similarity of a clean signal presented to the CI ear and candidate, CI-like signals presented to the ear with normal hearing. Methods: For Experiment 1 four types of stimuli were created for presentation to the normal hearing ear: noise vocoded signals, sine vocoded signals, frequency shifted, sine vocoded signals and band-pass filtered, natural speech signals. Listeners rated the similarity of these signals to unmodified signals sent to the CI on a scale of 0 to 10 with 10 being a complete match to the CI signal. For Experiment 2 multitrack signal mixing was used to create natural speech signals that varied along multiple dimensions. Results: In Experiment 1 for eight adult SSD-CI listeners, the best median similarity rating to the sound of the CI for noise vocoded signals was 1.9; for sine vocoded signals 2.9; for frequency upshifted signals, 1.9; and for band pass filtered signals, 5.5. In Experiment 2 for three young listeners, combinations of band pass filtering and spectral smearing lead to ratings of 10. Conclusion: The sound quality of noise and sine vocoders does not generally correspond to the sound quality of cochlear implants fit to SSD patients. Our preliminary conclusion is that natural speech signals that have been muffled to one degree or another by band pass filtering and/or spectral smearing provide a close, but incomplete, match to CI sound quality for some patients.

Cellular therapies, such as stem cell–based treatments, have been widely researched and numerous products and treatments have been developed. Despite this, there has been relatively limited use of these technologies in the healthcare sector. This study sought to investigate the perceived barriers to this more widespread adoption. An anonymous online questionnaire was developed, based on the findings of a pilot study. This was distributed to an audience of clinicians, researchers and commercial experts in 13 countries. The results were analysed for all respondents, and also sub-grouped by geographical region, and by profession of respondents. The results of the study showed that the most significant barrier was manufacturing, with other factors such as efficacy, regulation and cost-effectiveness being identified by the different groups. This study further demonstrates the need for these important issues to be addressed during the development of cellular therapies to enable more widespread adoption of these treatments.

AbstractThe clinical significance of the c.427G>A (p.A143T) variant in GLA is a topic of debate within the lysosomal storage disease community. A review of the literature and published case reports found the clinical impact of the variant to range from classic Fabry symptoms to healthy unaffected males with normal alpha‐ galactosidase enzyme levels, leaving clinicians unsure of how to manage these individuals. As the number of states testing for Fabry disease on their newborn screening panel has increased, more people with this variant are being identified. The goal of this project was to learn how the uncertainty surrounding the clinical significance of the p.A143T variant affects those with this change. A self‐response questionnaire was developed to explore this topic. In addition to evaluating participant feelings, the questionnaire explored individuals’ beliefs regarding the pathogenicity of the variant. Results suggest that people have diverse feelings regarding reclassification of the p.A143T variant. Around half of those surveyed reported feeling frustrated by the lack of clear information. Despite the ambiguity regarding the health consequences of this variant, many participants felt that knowing this result helps guide medical management.

Accurate risk stratification of smooth muscle tumors (SMTs) is essential for appropriate patient management. Yet, the rarity of SMTs of the vagina and vulva makes development of a prognostically meaningful classification system challenging. While 2 classification methods for vulvar SMTs and 1 for vaginal SMTs have been proposed, it is our experience that many pathologists tend to apply criteria for uterine SMTs when evaluating vulvovaginal tumors. We retrospectively reviewed a large cohort of vulvovaginal SMTs with clinical follow-up and evaluated which method most accurately classified tumors according to patient outcome. A total of 71 tumors, 53 vaginal (75%) and 18 vulvar (25%), from 71 patients were identified. All tumors were centrally examined for degree of cytologic atypia, morphology (spindled, epithelioid, myxoid), mitotic index per 10 high power fields, atypical mitotic figures, tumor cell necrosis, ischemic necrosis, tumor interface (circumscribed or infiltrative) and margin status. Clinical features were recorded for each patient. Follow-up was available for 63 patients (89%), and ranged from 1 to 234 months (median: 64 mo). While site-specific and uterine criteria showed equally excellent sensitivity in classifying smooth muscle neoplasms as leiomyosarcoma according to patient outcome, uterine criteria showed improved specificity relatively to site-specific methods in classifying tumors as nonsarcoma according to patient outcome. We recommend that uterine SMT criteria and nomenclature be adopted for evaluation and classification of vulvovaginal SMTs.

Abstract Background: In vivo synergy with concurrent PI3-Kinase inhibition and PARP inhibition has been observed in BRCA-deficient and BRCA-proficient preclinical models of triple negative breast cancer (TNBC) and ovarian cancer (OC). A phase I trial of the oral pan-class I PI3-Kinase inhibitor BKM120 and the PARP inhibitor olaparib demonstrated anti-cancer activity in TNBC and OC, both in patients with and without germline BRCA1 and BRCA2 (BRCA) mutations. However, CNS toxicity (depression) and liver function test abnormalities limited dose escalation of BKM120 prompting evaluation of the alpha specific PI3-Kinase inhibitor BYL719 (which has no CNS toxicity) in combination with olaparib. Methods: Olaparib was administered twice daily (tablet formulation) and BYL719 daily on a 28-day cycle, both orally. A 3 + 3 dose-escalation design was employed with primary objectives of defining the maximum tolerated dose (MTD) and recommended phase 2 dose of the combination of BYL719 and olaparib, and secondary objectives of defining toxicity, activity, and pharmacokinetic profiles of both agents. Eligibility included recurrent TNBC or high grade serous (HGS) OC, or any histology OC or breast cancer (BC) with presence of a known germline BRCA mutation, performance status of 0-1 and measurable/evaluable cancer. Patients with platinum sensitive or resistant or refractory OC were eligible and prior PARP inhibitor use was allowed. Dose-expansion cohorts at the MTD were enrolled for both BC and OC. Results: 46 patients (16 BC and 30 OC) have been enrolled in the study; 28 patients participated in the dose escalation portion of the study (4 BC and 24 OC). Two patients with OC did not receive study drugs because of ineligibility. MTD was defined as BYL719 200mg once daily and olaparib 200mg twice daily. Dose limiting toxicities included hyperglycemia, rash and fever with decreased neutrophil count. Four patients (3 OC and 1 BC) discontinued protocol therapy because of toxicity (2 for hyperglycemia, 1 for nausea and 1 for allergic reaction). Most common toxicities included nausea, hyperglycemia, fatigue, diarrhea and vomiting. At the MTD, 6 patients with OC and 12 patients with BC were enrolled into a dose expansion cohort. The OC expansion cohort has completed enrollment, while the BC cohort is still enrolling. Among patients with OC who received study drugs (28 patients, 26 (93%) with platinum resistant disease), objective response rate (ORR) by RECIST 1.1 was 36% (10/28 patients, all partial responses (PRs)). Median duration of response was 167 days (range 16-398 days); 5 of 10 patients with PR remain on treatment. ORR was 33% for patients with germline BRCA mutations and 31% for patients without germline BRCA mutations. Among patients without germline BRCA mutations with platinum resistant OC, ORR was 29%. Conclusions: Combined BYL719 and olaparib is feasible, and similar clinical benefit was observed in patients with and without germline BRCA mutations. The activity of this combination in OC patients without germline BRCA mutations and with platinum resistant disease was higher than expected from olaparib monotherapy and warrants further investigation.

Abstract Cancer has been considered a heterogeneous disease, which mainly arises from the accumulation of genetic mutations, leading to a loss of tumor suppressor genes, as well as to an activation of oncogenes. The epigenetic mechanisms, such as DNA and histone modifications, are processes that regulate gene expression, and an alteration of these can contribute to cancer progression. Methylation on histone 3 lysine 9 (H3K9), in particular di-methyl (H3K9me2), is mainly mediated by the nuclear histone lysine methyltransferase G9a. Preliminary data showed that G9a was overexpressed in aggressive and highly metastatic forms of cancer. However, to date, this pathway has remained unstudied in esophageal adenocarcinoma. Interestingly, epigenetic drugs, such as those that target G9a, have the potential to reverse the adverse effects acquired downstream from genetic mutations, which currently cannot be directly repaired or targeted. In the current study, we utilize BRD4770, an S-adenosylmethionine (SAM) mimetic inhibitor of G9a, to determine the benefits of inhibiting this pathway in the context of esophageal adenocarcinoma. We hypothesize that pharmacological targeting of G9a by BRD4770 inhibits esophageal adenocarcinoma cell growth. To examine G9a-mediated dimethyl histone H3K9 levels in esophageal adenocarcinoma, we performed immunohistochemistry on paraffin-embedded esophageal adenocarcinoma tissues with an H3K9me2 antibody. In order to confirm specificity of BRD4770 in regulating the dimethyl histone H3K9 levels, and thus trimethyl H3K9 levels, in esophageal adenocarcinoma, we treated human esophageal adenocarcinoma cells (SKGT-4) with different doses of BRD4770 at various time points for western blot analysis using antibodies against histone H3K9me2 and H3K9me3. Moreover, we found that treatment of SKGT-4 cells with BRD4770 significantly inhibits cell proliferation by MTS assay, as well as clonogenic survival. Therefore, to determine the mechanism(s) by which BRD4770 inhibits the growth of esophageal adenocarcinoma cells, we utilized Caspase-3, Senescence, and Autophagy Assays. Our data shows that inhibition of G9a by BRD4770 does not induce Caspase 3 activity, while it significantly increases senescence and autophagy. Combined, our results suggest that BRD4770 has an important pharmacological role in regulating methyl histone H3K9 levels that may lead to inhibition of esophageal adenocarcinoma cell growth via an increase in senescence and autophagy. Further studies are focused on in vivo models to understand these effects in more detail, however the fact that an anti-G9a drug antagonizes esophageal adenocarcinoma cell growth raises optimism for its potential in the treatment of this malignancy.

Abstract Background: Patients (pts) with CLL/SLL who use unmutated IGHV (u-CLL) have a less favorable outcome with standard chemotherapy than pts who use mutated IGHV (m-CLL). Ibrutinib (ibr) inhibits B-cell receptor signaling through Bruton’s tyrosine kinase and has robust clinical activity against CLL. This integrated analysis of 3 phase 3 studies examined the impact of IGHV status on ibr- and comparator (comp)-treated pts. Methods: Pooled data from 3 studies of ibr (420 mg/d) in CLL/SLL pts (RESONATE: relapsed/refractory [R/R] pts, ibr vs ≤ 24 weeks ofatumumab; RESONATE-2: treatment-naïve [TN] pts ≥ 65 yrs of age [no del17p], ibr vs ≤ 12 cycles chlorambucil; HELIOS: R/R pts [no del17p], ≤ 6 cycles bendamustine-rituximab with ibr vs placebo) were analyzed by IGHV status. Analyses included Kaplan-Meier method (overall survival [OS]; progression-free survival [PFS]); log-rank test (group comparisons); and Cox multivariate analysis (prognostic factors; Table). Results: For 491 ibr- (366 u-CLL, 125 m-CLL) and 494 comp-treated (351 u-CLL, 143 m-CLL) pts with IGHV data, baseline characteristics were similar for u-CLL vs m-CLL, except for the proportions of pts who were TN (17 vs 31%), had bulky disease (60 vs 37%), or had CLL cells with del11q (32 vs 16%). Median follow up was 21.4 mos for ibr and 20.6 mos for comp. PFS and OS were similar for u-CLL and m-CLL ibr-treated pts; u-CLL had poorer outcomes than m-CLL in comp-treated pts, which remained after adjustment for prognostic factors (Table). Ibr treatment was more effective than comp regardless of IGHV status. Incidence of adverse events (AEs) was similar between groups. For ibr vs comp pts (u-CLL/m-CLL): serious AEs: 49% (50%/47%) vs 36.5% (37%/35%); AEs that led to discontinuation: 12% (11%/15%) vs 13% (13%/14%); death within 30 days of last dose: 5% (6%/3%) vs 5% (6%/2%). Conclusions: U-CLL was an adverse predictor of outcome for comp-treated, but not for ibr-treated pts.

Abstract Background: There have been varying reports on risk of different cancers, other than pancreatic cancer (PC), among first-degree relatives (FDRs) of PC patients. Because the pattern and scope of aggregation of PC with other malignancies in families of PC patients are not entirely clear, we investigated risk of 15 common malignancies among FDRs of unselected PC probands. Methods: The study included 17,181 FDRs with more than 336,000 person-years at risk. The FDRs were identified through sequentially enrolled PC probands (n=2,305) in the Mayo Clinic prospective pancreatic cancer patient registry from 2000-2016. Data on family history of cancer were provided by the probands at the time of enrollment in structured risk factor questionnaires. Standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) were calculated by comparing cases of each cancer type observed among the FDRs with those expected using data from the Surveillance Epidemiology and End Results Program (SEER). Stratified analyses were performed among siblings of the probands based on whether the related proband tested positive for a mutation in ATM, BARD1, BRCA1, BRCA2, CDKN2A, CHEK2, MUTYH, NBN, PALB2, or PMS2; or tested negative for mutation in a total of 25 sequenced cancer susceptibility genes. Results: Compared to the SEER reference population, risk of PC was two-fold higher than expected among the FDRs (SIR=2.04, 95% CI: 1.78-2.31) and 12-fold higher than expected among FDRs with history of PC in at least two blood relatives (SIR=11.99, 95% CI: 10.48-13.64). Siblings of mutation-positive probands had higher risk of PC (SIR=13.57, 95% CI: 6.19-25.76) than siblings of mutation-negative probands (SIR=8.91, 95% CI=6.73-11.57). For other cancer types, primary liver cancer was elevated among female FDRs (SIR=2.10, 95% CI: 1.34-3.12), whereas breast (SIR=3.16, 95% CI: 1.63-5.52) and ovarian (SIR =6.61, 95% CI: 1.33-19.31) cancers were elevated only among siblings of the mutation-positive probands. There also were suggestions of lower than expected risk of other malignancies, such as bladder, colorectal and prostate cancers, among the FDRs as compared with the SEER population. Conclusions: These findings confirm familial aggregation of PC with breast and ovarian cancers, and further suggest a potential aggregation of PC and primary liver cancer among female FDRs of PC probands. The elevated risks of breast cancer and ovarian cancer among siblings of the mutation-positive probands suggests a strong influence of genetic susceptibility shared with the related proband, possibly due to an inherited mutation in BRCA1, BRCA2, or PALB2. These findings lend support to genetic counseling and targeted screening of certain cancers in high-risk families. Citation Format: Samuel O. Antwi, Sarah E. Fagan, Kari G. Chaffee, William R.

Abstract Background: Accumulating epidemiological studies positively associate healthy body mass index (BMI) and higher physical activity with lowered risk of postmenopausal breast cancer. Many of the proposed biomarkers underlying these associations, such as insulin, inflammatory markers, steroid hormones, and adipokines, are produced or regulated by adipose tissue. However, the biological impact of lifestyle factors at the level of the breast tissue, particularly adipose tissue in the breast, is unclear and may play a role in the etiology of breast cancer. Methods: Using a cross-sectional design, we examined the impact of demographic and lifestyle factors on histological features of breast adipose tissue. Women (age) undergoing reduction mammoplasty surgery were consented to collection of their cancer-free breast tissue at the time of surgery. An adipose rich section of the sample was dissected under sterile conditions and formalin fixed. Samples were sectioned at 7 µm thickness and stained with hematoxylin and eosin. The stained sections were imaged and mean adipocyte size was determined as diameter (µm) from 3 randomly selected areas at 10X magnification and each sample was scored by two independent assessors using Image J software. BMI status documented at the time of surgery was abstracted form medical records. A subset of women completed an additional visit where percent total body fat was measured by air displacement plethysmography and aerobic fitness (VO2peak) was measured by a maximal graded exercise test with expired gas collection. The association between adipocyte size and demographic/lifestyle factors was examined using multivariate linear regression adjusted for age and menopausal status. Results: Participants (n=42) were primarily Caucasian (77%) and pre/peri-menopausal (62%), with a mean age of 44.6±12.9 years (range 19-70) and mean BMI of 27.7±5.1 kg/m2 (range 19.1-37.4). Adipocyte size was associated with BMI (per 5 kg/m2 increase, β = 5.6±2.15, p=0.01) and number of pregnancies (β = 6.04±2.34, p=0.02), but not age (β = 0.1±0.3, p=0.81). In the subset of participants who completed an additional study visit (n=9), there was a trend towards an inverse association between adipocyte size and aerobic fitness (per 2 ml/kg/min of O2 consumption, β = -3.54±1.52, p=0.07) and percent body fat (per 2% increase, β = 1.94±1.28, p=0.17) in unadjusted analyses. Conclusion: Higher BMI is associated with larger adipocyte size in adipose tissue taken from the breast, suggesting a biological role for body composition in influencing gross histological features of adipocytes and its behavior that would impact the health of the mammary gland. A better understanding of the biological mechanisms underlying the observed epidemiological associations are needed to guide the development of intervention strategies and the most effective public health messages for breast cancer prevention.

Abstract By regulating gene expression networks that mediate neoplastic behavior, epigenetic protein complexes are the ultimate effectors of oncogenic pathways. This hierarchical position of epigenetic pathways within the mechanisms that regulate cancer makes them ideal candidates for therapeutic targets. The current work was designed to characterize the role of the K9H3 Histone Methyltransferase (HMT) pathway in mediating oncogenic signals downstream of Aurora Kinase A (AurkA), with the goal of designing efficient combinatorial therapies against PDAC. Affinity protein purification, combined with mass spectrometry, demonstrates that HP1γ isolated from mitotic cells interacts with AurkA and the HMTs, G9a and GLP. We also find that this complex is critical for mitotic progression and cell proliferation. Congruently, treatment of PDAC cells with individual drugs against AurkA or HP1-HMT inhibits cell growth by inducing senescence, a cytostatic response. However, the combination of these agents has a synergistic effect of reducing cell growth in both, monolayer and spheroid cultures to result in a cytotoxic effect. Confocal and electron microscopy, along with cell cycle analysis, demonstrate that the cytotoxic effect of this combination is due to induction of mitotic catastrophe, a distinct form of cell death that occurs during mitosis. Molecularly, the combination of AurkA and HP1-HMT inhibition bypasses G2/M arrest with downregulation of the Chk1-Cdc25c pathway. In vivo treatment of PDAC orthotopic xenografts with the HP1-HMT inhibitor alone demonstrated reduced PDAC growth, and increased efficacy in PDAC growth reduction was observed in combination with the AurkA inhibitor over either individual treatment. Thus, our data demonstrate a novel AurkA-HP1-HMT mitotic pathway that holds promise for potential pharmacological targeting in combinatorial therapy for this malignancy.
