Abstract Introduction Alcoholism is a growing problem with increasing incidence on in women. The aim of our study was to evaluate drinking habits in women using Alcohol Use Disorders Identification Test (AUDIT), and to look for differences in relations to respondents’ demographic, behavioral, and medical characteristics. Methods This cross-sectional study included 327 adult women who did not visit a physician due to liver enzymes abnormalities or any other significant health issue. All subjects filled in a questionnaire consisting of socio-demographic survey and the AUDIT. Results The statistically significant influence of the respondents’ age on the answers to the AUDIT was observed in Q1-Q5, Q7, and Q8, and in alcohol use risk groups. It was observed that women with a university degree use alcohol more often, compared to those who have attended primary, or middle school. The effect of responders’ employment status demonstrated a statistically significant difference in response to Q3, Q5, Q7, and Q8, and in alcohol use risk groups. We found that marital status contributes to drinking patterns. We found statistically significant difference to the answers on Q1-Q3, Q5, Q7, and Q8. The effect of offspring on the answers on the AUDIT was analyzed and a statistically significant difference was noted in the answers to the Q1-Q3, Q5, Q7, Q8, and in alcohol use risk groups. Conclusion Alcohol use among women is commonly and severely overlooked. Our results showed younger women, the unemployed, those in domestic partnerships, single ones and those with no children deserve increased surveillance.

Abstract Pancreatic neuroendocrine tumors (PNETs) are the second most common neoplasm of the pancreas after ductal adenocarcinoma. The clinical behavior of PNETs is very difficult to predict, especially for well-differentiated PNETs. Several classification systems have been developed to differentiate benign from malignant PNETs. The current 5th edition WHO (2019) updated the grading system of PNETs which is now entirely based on proliferative rate (either mitotic count or Ki-67 index). In this article, we systemically reviewed the evolution of the histologic classification and grading systems for well-differentiated PNETs. Meanwhile, we also report a comprehensive summary of immunohistochemical and molecular prognostic factors for PNETs patients, including CK19, KIT, PD-L1/PD-L1, UCH-L1 and CNPY2. We believe that more reliable grading systems and prognostic markers are emerging and will change the landscape of treatment for well-differentiated PNETs.

Abstract Genome-wide association studies (GWAS) of esophageal adenocarcinoma (EAC) and its precursor, Barrett’s esophagus (BE), have uncovered significant genetic components of risk, but most heritability remains unexplained. Targeted assessment of genetic variation in biologically relevant pathways using novel analytical approaches may identify missed susceptibility signals. Central obesity, a key BE/EAC risk factor, is linked to systemic inflammation, altered hormonal signaling and insulin-like growth factor (IGF) axis dysfunction. Here, we assessed IGF-related genetic variation and risk of BE and EAC. Principal component analysis was employed to evaluate pathway-level and gene-level associations with BE/EAC, using genotypes for 270 single-nucleotide polymorphisms (SNPs) in or near 12 IGF-related genes, ascertained from 3295 BE cases, 2515 EAC cases and 3207 controls in the Barrett’s and Esophageal Adenocarcinoma Consortium (BEACON) GWAS. Gene-level signals were assessed using Multi-marker Analysis of GenoMic Annotation (MAGMA) and SNP summary statistics from BEACON and an expanded GWAS meta-analysis (6167 BE cases, 4112 EAC cases, 17 159 controls). Global variation in the IGF pathway was associated with risk of BE (P = 0.0015). Gene-level associations with BE were observed for GHR (growth hormone receptor; P = 0.00046, false discovery rate q = 0.0056) and IGF1R (IGF1 receptor; P = 0.0090, q = 0.0542). These gene-level signals remained significant at q < 0.1 when assessed using data from the largest available BE/EAC GWAS meta-analysis. No significant associations were observed for EAC. This study represents the most comprehensive evaluation to date of inherited genetic variation in the IGF pathway and BE/EAC risk, providing novel evidence that variation in two genes encoding cell-surface receptors, GHR and IGF1R, may influence risk of BE.

Abstract PAC203 is a randomized dose-finding study of pacritinib, an oral JAK2/IRAK1 inhibitor, in patients with advanced myelofibrosis who are intolerant of or resistant to ruxolitinib. Patients were randomized 1:1:1 to pacritinib 100 mg once per day, 100 mg twice per day, or 200 mg twice per day. Enhanced eligibility criteria, monitoring, and dose modifications were implemented to mitigate risk of cardiac and hemorrhagic events. Efficacy was based on ≥35% spleen volume response (SVR) and ≥50% reduction in the 7-component total symptom score (TSS) through week 24. Of 161 patients, 73% were intolerant of and 76% had become resistant to ruxolitinib; 50% met criteria for both. Severe thrombocytopenia (platelet count <50 × 103/μL) was present in 44%. SVR rates were highest with 200 mg twice per day (100 mg once per day, 0%; 100 mg twice per day, 1.8%; 200 mg twice per day, 9.3%), particularly among patients with baseline platelet counts <50 × 103/μL (17%; 4 of 24). Although TSS response rate was similar across doses (100 mg once per day, 7.7%; 100 mg twice per day, 7.3%; 200 mg twice per day, 7.4%), median percent reduction in TSS suggested a dose-response relationship (–3%, −16%, and −27%, respectively). Pharmacokinetic and pharmacodynamic modeling based on all available data showed greatest SVR and TSS reduction at 200 mg twice per day compared with lower doses. Common adverse events were gastrointestinal events, thrombocytopenia, and anemia. There was no excess of grade ≥3 hemorrhagic or cardiac events at 200 mg twice per day. Pacritinib 200 mg twice per day demonstrated clinical activity and an acceptable safety profile and was selected as the recommended dose for a pivotal phase 3 study in patients with myelofibrosis and severe thrombocytopenia. This trial was registered at www.clinicaltrials.gov as #NCT03165734.

Objectives: To assess if excess absolute risk (EAR) of radiation-induced solid cancer can be used to rank radiotherapy plans for treatment of Hodgkin lymphoma (HL) in a statistically significant way. Methods: EAR models, calibrated with data from the Life Span Study and HL survivors, have been incorporated into a voxelised risk-calculation software, which is used to compare four treatment modalities planned for five virtual HL patients. Organ-specific parameters are generated repeatedly in a Monte Carlo fashion to model their uncertainties. This in turn enables a quantitative estimation of the EAR uncertainties. Results: Parameter-driven uncertainties on total EAR are around 13%, decreasing to around 2–5% for relative EAR comparisons. Total EAR estimations indicate that intensity modulated proton therapy decreases the average risk by 40% compared to the intensity modulated radiation therapy plan, 28% compared to the volumetric modulated arc therapy plan whereas the three-dimensional conformal radiation therapy plan is equivalent within the uncertainty. Conclusion: Relative EAR is a useful metric for distinguishing between radiotherapy plans in terms of second cancer risk. Advances in knowledge: Relative EAR is not dominated by model or parameter uncertainties and can be used to guide the choice of radiotherapy for HL patients.

BACKGROUND: MF is characterized by anemia, splenomegaly, debilitating constitutional symptoms, and shortened survival. Fedratinib is an oral JAK2 inhibitor approved in the United States for treatment (Tx) of adult patients (pts) with intermediate (INT)-2 or high-risk MF. The randomized, placebo (PBO)-controlled, phase III JAKARTA trial evaluated clinical outcomes with fedratinib in pts with JAK-inhibitor-naïve MF. Initial findings from the JAKARTA study have been reported (Pardanani, JAMA Oncol, 2015). JAKARTA data were recently reanalyzed in preparation for regulatory review. OBJECTIVE: Evaluate the clinical efficacy and safety with fedratinib 400 mg/day in updated analyses of the JAKARTA study. METHODS: JAKARTA was an international, randomized, double-blind, PBO-controlled study that enrolled pts aged ≥ 18 years with INT-2 or high-risk primary, post-PV, or post-ET MF. Pts were randomly assigned 1:1:1 to fedratinib 400 mg, fedratinib 500 mg, or PBO, administered orally once-daily for ≥ 6 consecutive 4-week cycles ("randomized Tx period"). After completing 6 Tx cycles (or earlier in the case of disease progression), pts randomized to PBO could crossover to fedratinib. The primary endpoint was the spleen volume response rate (SVRR), the proportion of pts who achieved a ≥ 35% spleen volume reduction from baseline (BL) confirmed by MRI/CT at end of cycle 6 (EOC6), confirmed by follow-up scan 4 weeks later. Secondary endpoints included SVRR without 4-week confirmation, durability of spleen response, and symptom response rate (proportion of pts with a ≥ 50% reduction from BL in total symptom score [TSS] on the modified Myelofibrosis Symptom Assessment Form [MFSAF]) at EOC6. An exploratory analysis evaluated proportions of pts with ≥ 50% reductions from BL at EOC6 in individual MFSAF symptom scores: night sweats, pruritus, abdominal discomfort, early satiety, pain under ribs on left side, and bone or muscle pain. These analyses are limited to pts randomized to fedratinib 400 mg (the approved starting dose of fedratinib) or to PBO. Efficacy analyses were performed for the intention-to-treat (ITT) population and safety was assessed in all pts who received ≥ 1 dose of study drug. RESULTS: 96 pts were randomized to fedratinib 400 mg and 96 pts to PBO. In the fedratinib and PBO arms, median ages at BL were 63 (range 39-86) and 66 (27-85) years, respectively, 65% and 60% of pts had primary MF, 76% and 73% had constitutional symptoms, median spleen volumes were 2652 (316-6430) and 2660 (662-7911) mL, and median TSS were 15.3 (0-57) and 12.4 (0-53). Median durations of exposure were 15.5 months in the fedratinib 400 mg arm and 6 months in the PBO arm. With a confirmation scan 4 weeks after EOC6, SVRR was significantly higher in the fedratinib arm (37% [95%CI 27%, 46%]) vs. the PBO arm (1% [0%, 3%]) (P < 0.0001). Without the confirmation scan, SVRR at EOC6 was 47% (95%CI 37%, 57%) in the fedratinib 400 mg arm and 1% (0%, 3%) in the PBO arm (P < 0.0001; Figure). Estimated median duration of spleen response with fedratinib was 18.2 months. Symptom response rate at EOC6 for evaluable pts (ie, with TSS data available at BL and EOC6) was 40% (36/89) with fedratinib and 9% (7/81) with PBO (P < 0.0001). Fedratinib was associated with higher response rates vs. PBO in all 6 MFSAF symptoms: abdominal discomfort (41% vs. 15%, respectively), night sweats (58% vs. 22%), bone or muscle pain (33% vs. 14%), early satiety (51% vs. 18%), pruritus (39% vs. 20%), and pain under the ribs on the left side (42% vs. 24%). The most common Tx-emergent adverse events (TEAEs) during the randomized Tx period were grade 1-2 gastrointestinal events (Table). New or worsening grade 3 anemia and grade ≥ 3 thrombocytopenia laboratory abnormalities were reported in 34% and 12% of fedratinib-treated pts, most (75%) occurring within 3-4 months of Tx initiation. Compared with PBO, fedratinib-treated pts more frequently experienced increased serum creatinine, amylase, and lipase; these were mainly grade 1-2 in severity. TEAEs led to Tx discontinuation for 14% of fedratinib pts and 8% of PBO pts. CONCLUSIONS: Fedratinib 400 mg/day significantly reduced splenomegaly and symptom burden in pts with JAK-inhibitor-naïve MF. Relatively few pts discontinued fedratinib therapy due to TEAEs, suggesting these events are manageable. These data corroborate results initially reported for the JAKARTA trial, and further support the efficacy and safety of fedratinib in this pt population.

Aim Migraine pain is thought to result from activation of meningeal nociceptors that might involve dural mast cell degranulation and release of proteases and pronociceptive mediators. Tryptase, the most abundant dural mast cell protease, has been demonstrated to stimulate dural mast cells, as well as trigeminal nociceptors by activating the protease activated receptor 2. Mast cell or neuronal protease activated receptors 2 may therefore represent a novel target for migraine treatment. In this study, we characterized and evaluated a novel protease activated receptor 2 monoclonal antibody as a preventive anti-migraine pain therapy in preclinical models. Methods Flow cytometry, immunocytochemistry, calcium imaging, Homogeneous Time Resolved Technology (HTRF) epitope competition assay and serum pharmacokinetic (PK) assay in rats were performed to confirm the activity, specificity and in vivo stability of PAR650097, a novel anti- protease activated receptor 2 monoclonal antibody. In vivo assessment was performed in female C57BL/6J mice by evaluation of PAR650097 in preventing cutaneous allodynia elicited by (a) supradural injection of the protease activated receptor 2 agonist, Ser-Leu-Ile-Gly-Arg-Leu-amide trifluoroacetate (SLIGRL), or calcitonin gene-related (CGRP) peptide, and (b) induction of latent sensitization by priming with three daily episodes of restraint stress followed by challenge with a subthreshold inhalational exposure to umbellulone (UMB), a transient receptor potential ankyrin 1 (TRPA1) agonist. PAR650097 was administered as a pretreatment prior to the first restraint stress, umbellulone exposure, SLIGRL or calcitonin gene-related peptide injection. Additionally, fremanezumab, a calcitonin gene-related peptide antibody was administered as pre-treatment prior to supradural administration of calcitonin gene-related peptide or SLIGRL. Results In vitro, PAR650097 demonstrated rapid interaction with protease activated receptor 2, enabling it to fully inhibit protease-induced protease activated receptor 2 activation, in human and mouse cells, with high potency. Furthermore, PAR650097 was highly selective for protease activated receptor 2, demonstrating no affinity for protease activated receptor 1 protein and no functional effect on the activation of cellular protease activated receptor 1 with thrombin. In addition, PAR650097 had an acceptable PK profile, compatible with testing the effects of selective protease activated receptor 2 inhibition in vivo. In vivo, PAR650097 blocked cutaneous allodynia induced by either supradural SLIGRL or calcitonin gene-related peptide. Fremanezumab abolished cutaneous allodynia induced by supradural CGRP, and partially attenuated cutaneous allodynia induced by SLIGRL. Administration of PAR650097, before the first restraint stress episode, did not prevent the acute stress-induced cutaneous allodynia or restraint stress priming revealed by cutaneous allodynia induced by inhalational umbellulone. In contrast, PAR650097 prevented expression of cutaneous allodynia when given before the umbellulone challenge in restraint stress-primed animals. Conclusion PAR650097 specifically inhibits endogenously expressed protease activated receptor 2 in human and mouse cells with high potency. This antibody has an acceptable PK profile in rodents and effectively blocked SLIGR-induced cutaneous allodynia. PAR650097 additionally prevented cutaneous allodynia induced by supradural calcitonin gene-related peptide, indicating that the protease activated receptor 2 receptor is a downstream consequence of calcitonin gene-related peptide actions. Fremanezumab effectively blocked calcitonin gene-related peptide-induced cutaneous allodynia and only partially reduced cutaneous allodynia induced by a protease activated receptor 2 activator, suggesting both calcitonin gene-related peptide-dependent and -independent mechanisms in promoting migraine pain. While PAR650097 did not prevent stress-induced cutaneous allodynia or priming, it effectively prevented cutaneous allodynia induced by a TRPA1 agonist in animals with latent sensitization. Activation of protease activated receptor 2, therefore, contributes to both calcitonin gene-related peptide-dependent and -independent mechanisms in promoting migraine-like pain. Therapeutic targeting of protease activated receptor 2 receptors may represent an anti-migraine pain strategy with a potentially broad efficacy profile.
