PROMISE Registry: A prostate cancer registry of outcomes and germline mutations for improved survival and treatment effectiveness.

BACKGROUND: Recently approved treatments and updates to genetic testing recommendations for prostate cancer have created a need for correlated analyses of patient outcomes data via germline genetic mutation status. Genetic registries address these gaps by identifying candidates for recently approved targeted treatments, expanding clinical trial data examining specific gene mutations, and understanding effects of targeted treatments in the real-world setting. METHODS: The PROMISE Registry is a 20-year (5-year recruitment, 15-year follow-up), US-wide, prospective genetic registry for prostate cancer patients. Five thousand patients will be screened through an online at-home germline testing to identify and enroll 500 patients with germline mutations, including: pathogenic or likely pathogenic variants and variants of uncertain significance in genes of interest. Patients will be followed for 15 years and clinical data with real time patient reported outcomes will be collected. Eligible patients will enter long-term follow-up (6-month PRO surveys and medical record retrieval). As a virtual study with patient self-enrollment, the PROMISE Registry may fill gaps in genetics services in underserved areas and for patients within sufficient insurance coverage. RESULTS: The PROMISE Registry opened in May 2021. 2114 patients have enrolled to date across 48 US states and 23 recruiting sites. 202 patients have met criteria for long-term follow-up. PROMISE is on target with the study's goal of 5000 patients screened and 500 patients eligible for long-term follow-up by 2026. CONCLUSIONS: The PROMISE Registry is a novel, prospective, germline registry that will collect long-term patient outcomes data to address current gaps in understanding resulting from recently FDA-approved treatments and updates to genetic testing recommendations for prostate cancer. Through inclusion of a broad nationwide sample, including underserved patients and those unaffiliated with major academic centers, the PROMISE Registry aims to provide access to germline genetic testing and to collect data to understand disease characteristics and treatment responses across the disease spectrum for prostate cancer with rare germline genetic variants.

A single-institution retrospective exploratory analysis on the effectiveness and safety of lenvatinib plus pembrolizumab for advanced endometrial cancer: insights from ProMisE molecular classification system.

BACKGROUND: The Proactive Molecular Risk Classifier for Endometrial Cancer has identified four risk groups for the prognosis of endometrial cancer. Lenvatinib plus pembrolizumab was recently approved as a second-line treatment for unresectable endometrial cancer, but reports in clinical practice are lacking. The relationship between the efficacy of lenvatinib/pembrolizumab and Proactive Molecular Risk Classifier for Endometrial Cancer classification is unclear. METHODS: This single-centre retrospective study included patients who underwent lenvatinib/pembrolizumab therapy at Iwate Medical University Hospital between January 2022 and March 2023. Formalin-fixed paraffin-embedded specimens obtained from patients before treatment were collected and classified into the mismatch repair-deficient, p53 abnormal and no specific molecular profile subtypes using immunohistochemistry. The response rate, progression-free survival and adverse events were evaluated using electronic medical records. The study was approved by the hospital's ethics committee (approval number: MH2022-093). RESULTS: This study enrolled 20 patients, who underwent a median follow-up of 17.8 months (95% confidence interval: 16.6-18.9). The best overall response rate was 60.0% (36.1-80.9), and the median progression-free survival was 11.6 months (2.9-20.3). The median progression-free survival in the p53 abnormal group (n = 9) was 3.4 months (3.0-3.8); however, progression-free survival did not reach the median (P < 0.001) in the mismatch repair-deficient/no specific molecular profile group (n = 11). Symptomatic immune-related adverse events (except hypothyroidism) occurred in 4/20 (25.0%) patients, and partial responses were observed in all cases. No treatment-related deaths occurred. CONCLUSION: The p53abn group in the Proactive Molecular Risk Classifier for Endometrial Cancer classification has a poor prognosis even after treatment with lenvatinib/pembrolizumab.

If we know better, why don't we do better? A rapid quality improvement project to increase utilization of comfort measures to reduce pain and distress in children in a COVID-19 mass vaccination clinic.

INTRODUCTION: Many evidence-based tools exist to address pain and distress associated with injections; however, there remains a large gap between the knowledge of these tools and their utilization. Our hospital began a quality improvement (QI) project prior to COVID-19, with the goal of increasing the utilization of Comfort Promise measures during needle procedures. When COVID-19 vaccinations were approved, our mass vaccination clinics provided an opportunity to rapidly increase utilization across the institution. The primary aim was to increase the percentage of comfort measures (CM) offered with COVID-19 vaccinations. METHODS: Through this QI project, nurses and other professionals implemented CMs during COVID mass vaccination clinics. Clinics occurred in 3 age-based waves. Waves served as Plan-Do-Study-Act (PDSA) cycles. Families completed post-vaccination surveys to determine what CMs were offered and intention for future use with vaccinations. RESULTS: Uptake of CMs (PainEase, ShotBlockers, Comfort Positioning, Alternative Focus, Topical Lidocaine, and Breastfeeding/Sucrose) throughout the waves increased and generally remained stable. CMs also seemed to decrease pain/distress with vaccinations (70.5 to 88.7%), and children/caregivers intended to use some combination for future vaccinations (82.5 to 98.5%). CONCLUSIONS: Fast-paced mass vaccination clinics provided an ideal opportunity to significantly increase utilization of CMs. Across age groups CMs yielded high satisfaction and interest in future utilization. Clinic nurses returned to their own sub-specialties and became change agents. IMPLICATIONS: If all healthcare providers can work together to achieve consensus while incorporating comfort measures into daily practice, sustained change with incorporation of these evidence-based tools can be achieved. Future directions are discussed.

Establishing a plan to improve pediatric patient comfort during PIV insertions and blood specimen collection: a quality improvement effort.

HIGHLIGHTS: Patient comfort during peripheral intravenous (PIV) insertion and specimen collection was increased. The authors extended the contingency plan implemented for PICC insertion to include PIV insertion and specimen collection. The authors met their goals by using quality improvement methodology. Prioritizing patient comfort often requires institutional culture change. BACKGROUND: Needle procedures can cause pain and distress, especially in pediatric patients.1 Retrospective data collected at a freestanding pediatric facility revealed that approximately 30% of pediatric patients were not demonstrating sufficient levels of comfort during peripheral intravenous (PIV) catheter insertion and specimen collection (lab draws) even after successful implementation of comfort measures by the vascular access team (VAT) in an adjacent procedure (eg peripherally inserted central catheter placement). The current quality improvement project was implemented to support adaptation and expansion of previous lessons learned to PIVs and lab draws specifically. DESIGN AND METHODS: The VAT used the Pediatric Sedation State Scale,2 a standardized assessment tool integrated into the electronic medical record, to assess procedural comfort during PIVs and lab draws from February 2021 through April 2023. A total of 24 134 patients aged 0 to 18 years were included in the data collection. Interventions were delivered concurrently and included (1) reeducation/ongoing support for implementation of the Comfort Promise3 measures, (2) the creation and implementation of advanced comfort options, and (3) culture change. AIMS AND OBJECTIVES: The goal of the interventions was to improve the percentage of pediatric patients achieving adequate levels of comfort beginning at 68% in year 1 to 90% in year 2. RESULTS: From February 2021 to April 2023, the VAT team was able to improve procedural comfort scores from 68% to 90% of pediatric patients with adequate comfort for lab draws and/or PIV insertions. CONCLUSIONS: While standard comfort measures are a good first step in pain management during needle procedures, they are not sufficient for every pediatric patient. Nitrous, sedation, and the use of anxiolytics and analgesics can play an important role in reducing pain and anxiety during needle procedures and should be considered for patients not achieving adequate levels of comfort with standard comfort measures.

Test-retest repeatability of organ uptake on PSMA-targeted 18 F-DCFPyL PET/CT in patients with prostate cancer.

OBJECTIVES: We evaluated 18 F-DCFPyL test-retest repeatability of uptake in normal organs. METHODS: Twenty-two prostate cancer (PC) patients underwent two 18 F-DCFPyL PET scans within 7 days within a prospective clinical trial (NCT03793543). In both PET scans, uptake in normal organs (kidneys, spleen, liver, and salivary and lacrimal glands) was quantified. Repeatability was determined by using within-subject coefficient of variation (wCOV), with lower values indicating improved repeatability. RESULTS: For SUVmean , repeatability was high for kidneys, spleen, liver, and parotid glands (wCOV, range: 9.0%-14.3%) and lower for lacrimal (23.9%) and submandibular glands (12.4%). For SUVmax , however, the lacrimal (14.4%) and submandibular glands (6.9%) achieved higher repeatability, while for large organs (kidneys, liver, spleen, and parotid glands), repeatability was low (range: 14.1%-45.2%). CONCLUSION: We found acceptable repeatability of uptake on 18 F-DCFPyL PET for normal organs, in particular for SUVmean in the liver or parotid glands. This may have implications for both PSMA-targeted imaging and treatment, as patient selection for radioligand therapy and standardized frameworks for scan interpretation (PROMISE, E-PSMA) rely on uptake in those reference organs.

A Prospective Cohort Study Evaluating PAN-PROMISE, a Patient-reported Outcome Measure to Detect Post-ERCP Morbidity.

BACKGROUND & AIMS: The Cotton Consensus (CC) criteria for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) may not capture post-ERCP morbidity. PAN-PROMISE, a patient-reported outcome measure (PROM), was developed to quantify acute pancreatitis-related morbidity. This study aims to determine the value of PAN-PROMISE in independently defining ERCP-related morbidity. METHODS: We conducted a prospective cohort study of patients undergoing ERCP at 2 academic centers from September 2021 to August 2022. We administered PAN-PROMISE and assessed quality of life and work productivity at baseline, 48 to 72 hours, 7 days, and 30 days following ERCP. PEP was defined by a 3-physician committee using the CC criteria. We defined high morbidity following ERCP (elevated PROM) by an increase of PAN-PROMISE score of >7 at 7 days post-procedure. The McNemar test assessed discordance between PEP and elevated-PROM. RESULTS: A total of 679 patients were enrolled. Choledocholithiasis (30%) and malignant biliary obstruction (29%) were the main indications for ERCP. Thirty-two patients (4.7%) developed PEP. One hundred forty-seven patients (21.6%) had an elevated PROM, whereas only 20 of them (13.4%) had PEP by the CC criteria (P < .001 for discordance). An elevated PROM strongly correlated with lower physical quality of life and increased direct and indirect health care costs ($80 and $25 per point increase in PAN-PROMISE, respectively). Patients with pancreatic cancer (odds ratio, 4.52; 95% confidence interval, 1.68-10.74) and primary sclerosing cholangitis (odds ratio, 1.79; 95% confidence interval, 1.29-2.45) had the highest odds of elevated PROM. CONCLUSIONS: A substantial number of patients experience significant morbidity after ERCP despite not developing PEP or other adverse events. Future studies are needed to characterize better the reasons behind this increase in symptoms and potential interventions to reduce the symptom burden post-ERCP.

QTL mapping of shoot and seed traits impacted by Drought in Barley using a recombinant inbred line Population.

BACKGROUND: With ongoing climate change, drought events are severely limiting barley production worldwide and pose a significant risk to the malting, brewing and food industry. The genetic diversity inherent in the barley germplasm offers an important resource to develop stress resiliency. The purpose of this study was to identify novel, stable, and adaptive Quantitative Trait Loci (QTL), and candidate genes associated with drought tolerance. A recombinant inbred line (RIL) population (n = 192) developed from a cross between the drought tolerant 'Otis' barley variety, and susceptible 'Golden Promise'(GP) was subjected to short-term progressive drought during heading in the biotron. This population was also evaluated under irrigated and rainfed conditions in the field for yields and seed protein content. RESULTS: Barley 50k iSelect SNP Array was used to genotype the RIL population to elucidate drought-adaptive QTL. Twenty-three QTL (eleven for seed weight, eight for shoot dry weight and four for protein content) were identified across several barley chromosomes. QTL analysis identified genomic regions on chromosome 2 and 5 H that appear to be stable across both environments and accounted for nearly 60% variation in shoot weight and 17.6% variation in seed protein content. QTL at approximately 29 Mbp on chromosome 2 H and 488 Mbp on chromosome 5 H are in very close proximity to ascorbate peroxidase (APX) and in the coding sequence of the Dirigent (DIR) gene, respectively. Both APX and DIR are well-known key players in abiotic stress tolerance in several plants. In the quest to identify key recombinants with improved tolerance to drought (like Otis) and good malting profiles (like GP), five drought tolerant RILs were selected for malt quality analysis. The selected drought tolerant RILs exhibited one or more traits that were outside the realms of the suggested limits for acceptable commercial malting quality. CONCLUSIONS: The candidate genes can be used for marker assisted selection and/or genetic manipulation to develop barley cultivars with improved tolerance to drought. RILs with genetic network reshuffling necessary to generate drought tolerance of Otis and favorable malting quality attributes of GP may be realized by screening a larger population.

Clinical characteristics and prognostic characterization of endometrial carcinoma: a comparative analysis of molecular typing protocols.

BACKGROUND: Endometrial carcinoma (EC) is one of the most common gynecological malignancies in China and globally, accounting for the fourth-prevalent cancer in women. Although numerous studies have confirmed prognostic value of The Cancer Genome Atlas (TCGA) molecular subgroups, it is unclear how they are combined with histological features. The main objective of this study was to compare ProMisE and TCGA classification for the rapid and accurate prediction of prognosis within EC patients, together with the provision of a revised strategy for individualized diagnosis and treatment of patients. METHODS: Within this study, 70 patients with EC from Beijing Tsinghua Changgeng Hospital (affiliated to Tsinghua University) were retrospectively examined between July 2015 and December 2021. Samples were processed for determination of clinical markers, together with ProMisE and TCGA classification. RESULTS: Comparative analysis across four TCGA types (POLE, Low-CN, High-CN, and MSI-H) and age, was statistically significant (χ²= 7.000, p = 0.029). There was no significant difference observed among the four TCGA types and FIGO stage, vascular invasion and depth of invasion, or lymph node metastasis and tumor area. There was no significant association between the expression of Vimentin, Ki-67, PTEN, MSH2, PAX-8, ß-catenin, CD10, ER, PR, P16, MLH1, and PMS2 with the four TCGA types. In addition, p63 expression (χ²= 11.09, p = 0.029) and p53 expression (χ²= 11.585, p = 0.005) were statistically significant. Numerous models demonstrated that patients with POLE mutations and low-CN had higher progression free survival (PFS) and overall survival (OS), whereas those with high-CN had lowest values. The log-rank test revealed that the survival rate of PR-positive and ER-positive patients was significantly higher (p < 0.001). CONCLUSION: Overall, these results can be of additional benefit for clinical applications, in comparison to the ProMisE classification method. In addition, PR, ER, vascular infiltration, hyperlipidemia and atherosclerosis were found to be the key factors affecting EC prognosis.

Harmonized molecular classification; assessment of a single-test ProMisE NGS tool.

OBJECTIVES: Despite recommendations for integrating molecular classification of endometrial cancers (EC) into pathology reporting and clinical management, uptake is inconsistent. To assign ProMisE subtype, all molecular components must be available (POLE mutation status, mismatch repair (MMR) and p53 immunohistochemistry (IHC)) and often these are assessed at different stages of care and/or at different centres resulting in delays in treatment. We assessed a single-test DNA-based targeted next generation sequencing (NGS) molecular classifier (ProMisE NGS), comparing concordance and prognostic value to the original ProMisE classifier. METHODS: DNA was extracted from formalin-fixed paraffin embedded (FFPE) ECs that had previously undergone ProMisE molecular classification (POLE sequencing, IHC for p53 and MMR). DNA was sequenced using the clinically validated Imagia Canexia Health Find It™ amplicon-based NGS gene panel assay to assess for pathogenic POLE mutations (unchanged from original ProMisE), TP53 mutations (in lieu of p53 IHC), and microsatellite instability (MSI) (in lieu of MMR IHC),with the same order of segregation as original ProMisE used for subtype assignment. Molecular subtype assignment of both classifiers was compared by concordance metrics and Kaplan-Meier survival statistics. RESULTS: The new DNA-based NGS molecular classifier (ProMisE NGS) was used to determine the molecular subtype in 164 ECs previously classified with ProMisE. 159/164 cases were concordant with a kappa statistic of 0.96 and an overall accuracy of 0.97. Prognostic differences in progression-free, disease-specific and overall survival between the four molecular subtypes were observed for the new NGS classifier, recapitulating the survival curves of the original ProMisE classifier. ProMisE NGS was 100% concordant between matched biopsy and hysterectomy samples. CONCLUSION: ProMisE NGS is feasible on standard FFPE material, demonstrates high concordance with the original ProMisE classifier and maintains prognostic value in EC. This test has the potential to facilitate implementation of molecular classification of EC at the time of first diagnosis.

Clinical Effectiveness of Elexacaftor/Tezacaftor/Ivacaftor in People with Cystic Fibrosis: A Clinical Trial.

Rationale: The cystic fibrosis (CF) modulator drug, elexacaftor/tezacaftor/ivacaftor (ETI), proved highly effective in controlled clinical trials for individuals with at least one F508del allele, which occurs in at least 85% of people with CF. Objectives: PROMISE is a postapproval study to understand the broad effects of ETI through 30 months' clinical use in a more diverse U.S. patient population with planned analyses after 6 months. Methods: Prospective, observational study in 487 people with CF age 12 years or older with at least one F508del allele starting ETI for the first time. Assessments occurred before and 1, 3, and 6 months into ETI therapy. Outcomes included change in percent predicted FEV1 (ppFEV1), sweat chloride concentration, body mass index (BMI), and self-reported respiratory symptoms. Measurements and Main Results: Average age was 25.1 years, and 44.1% entered the study using tezacaftor/ivacaftor or lumacaftor/ivacaftor, whereas 6.7% were using ivacaftor, consistent with F508del homozygosity and G551D allele, respectively. At 6 months into ETI therapy, ppFEV1 improved 9.76 percentage points (95% confidence interval [CI], 8.76 to 10.76) from baseline, cystic fibrosis questionnaire-revised respiratory domain score improved 20.4 points (95% CI, 18.3 to 22.5), and sweat chloride decreased -41.7 mmol/L (95% CI, -43.8 to -39.6). BMI also significantly increased. Changes were larger in those naive to modulators but substantial in all groups, including those treated with ivacaftor at baseline. Conclusions: ETI by clinical prescription provided large improvements in lung function, respiratory symptoms, and BMI in a diverse population naive to modulator drug therapy, using existing two-drug combinations, or using ivacaftor alone. Each group also experienced significant reductions in sweat chloride concentration, which correlated with improved ppFEV1 in the overall study population. Clinical trial registered with www.clinicaltrials.gov (NCT NCT04038047).

High Salt Levels Reduced Dissimilarities in Root-Associated Microbiomes of Two Barley Genotypes.

Plants harbor in and at their roots bacterial microbiomes that contribute to their health and fitness. The microbiome composition is controlled by the environment and plant genotype. Previously, it was shown that the plant genotype-dependent dissimilarity of root microbiome composition of different species becomes smaller under drought stress. However, it remains unknown whether this reduced plant genotype-dependent effect is a specific response to drought stress or a more generic response to abiotic stress. To test this, we studied the effect of salt stress on two distinct barley (Hordeum vulgare L.) genotypes: the reference cultivar Golden Promise and the Algerian landrace AB. As inoculum, we used soil from salinized and degraded farmland on which barley was cultivated. Controlled laboratory experiments showed that plants inoculated with this soil displayed growth stimulation under high salt stress (200 mM) in a plant genotype-independent manner, whereas the landrace AB also showed significant growth stimulation at low salt concentrations. Subsequent analysis of the root microbiomes revealed a reduced dissimilarity of the bacterial communities of the two barley genotypes in response to high salt, especially in the endophytic compartment. High salt level did not reduce α-diversity (richness) in the endophytic compartment of both plant genotypes but was associated with an increased number of shared strains that respond positively to high salt. Among these, Pseudomonas spp. were most abundant. These findings suggest that the plant genotype-dependent microbiome composition is altered generically by abiotic stress.[Formula: see text] Copyright © 2022 The Author(s).

Clinical impact of genetic alterations of CTNNB1 in patients with grade 3 endometrial endometrioid carcinoma.

To identify prognostic factors in patients with grade 3 (high-grade) endometrial endometrioid carcinoma, we evaluated the spectrum of genomic alterations and examined whether previously reported molecular subtypes of endometrial carcinoma were adapted to clinical outcome prediction. Seventy-five Japanese patients with grade 3 endometrial endometrioid carcinoma, who underwent a potentially curative resection procedure between 1997 and 2018 at the National Cancer Center Hospital, were included. We classified the patients into four risk groups of the disease based on the Proactive Molecular Risk Classifier for Endometrial Cancer. Genomic alterations in PTEN, ARID1A, TP53, and PIK3CA were detected in more than 30% of the patients. Overall survival and recurrence-free survival of patients with genomic alterations in CTNNB1 were poorer than those of patients with wild-type CTNNB1 (p = 0.006 and p = 0.004, respectively). Compared with that of alterations prevalent in Caucasians, the frequency of genomic alterations in POLE and TP53 was higher in our study than in The Cancer Genome Atlas dataset (p = 0.01 and p = 0.01, respectively). The tendency for recurrence-free survival in the POLE exonuclease domain mutation group was better than that in the TP53 mutation and mismatch repair-deficient groups (p = 0.08 and p = 0.07, respectively), consistent with the Proactive Molecular Risk Classifier for Endometrial Cancer risk classifier definition. The CTNNB1 mutation is a potential novel biomarker for the prognosis of patients with grade 3 endometrial endometrioid carcinoma, and prognosis classification using Proactive Molecular Risk Classifier for Endometrial Cancer may help screen Japanese patients with the disease.

Lymphovascular space invasion in endometrial carcinoma: A prognostic factor independent from molecular signature.

BACKGROUND: The 2020 ESGO/ESTRO/ESP guidelines stratify the prognosis of endometrial carcinoma (EC) patients combining The Cancer Genome ATLAS (TCGA) molecular signature and pathological factors, including lymphovascular space invasion (LVSI). However, little is known about the prognostic independence of LVSI from molecular signature. AIM: To assess whether the prognostic value of LVSI is independent from the TCGA signature. MATERIAL AND METHODS: A systematic review and meta-analysis was performed by searching 5 electronic databases from their inception to March 2021. All peer-reviewed studies reporting assessing LVSI as a prognostic factor independent from the TCGA groups in EC were included. Multivariate HRs with 95% confidence interval (CI) were pooled separately for overall survival (OS), disease-specific survival (DSS) and disease-free survival (DFS). The absence of LVSI was considered as a reference. In DFS analyses, locoregional and distant recurrence were separately considered for one study. RESULTS: Six studies with 3331 patients were included in the systematic review and three studies with 2276 patients in the meta-analysis. LVSI showed a pooled multivariate HR of 1.818 (CI 95%, 1.378-2.399) for OS, 1.849 (CI 95%, 1.194-2.863) for DSS, 1.377 (CI 95%, 1.008-1.880) for DFS excluding one study, 1.651 (CI 95%, 1.044-2.611) for DFS additionally considering locoregional recurrence from one study, and 1.684 (CI 95%, 1.05-2.701) for DFS additionally considering distant recurrence from the same study. CONCLUSION: LVSI has a prognostic value independent of TCGA signature, as well as age and adjuvant treatment, increasing the risk of death of any cause, death due to EC and recurrent or progressive disease by 1.5-2 times.

Likelihood of response with subsequent dosing for patients with migraine and initial suboptimal response with eptinezumab: A post hoc analysis of two placebo-controlled randomized clinical trials.

OBJECTIVE: To develop a multivariable model assessing factors predicting a second-dose response to eptinezumab treatment over weeks 13-24 in patients with migraine initially reporting a suboptimal response over weeks 1-12. BACKGROUND: Eptinezumab is a monoclonal antibody used for migraine prevention, administered every 12 weeks. In the PROMISE-1 and PROMISE-2 studies, the first-dose response to eptinezumab treatment (≥50% monthly migraine day [MMD] reduction over weeks 1-12) occurred in ~50-60% of patients with episodic (EM) and chronic migraine (CM), respectively. METHODS: This post hoc analysis included patients with suboptimal first-dose response (<50% MMD reduction over weeks 1-12) with EM and CM, with patient-reported outcome data at weeks 12 and 24. Eptinezumab 100 and 300 mg doses were pooled. RESULTS: The analysis included 416/888 patients (46.8%) from PROMISE-1 and 479/1072 patients (44.7%) from PROMISE-2 with suboptimal first-dose response. The proportion of suboptimal first-dose responders who were second-dose responders was 37.0% (71/192; eptinezumab) and 33.9% (42/124; placebo) in PROMISE-1 and 28.8% (79/274) and 18.5% (38/205) in PROMISE-2. Significant first-dose predictors of second-dose response were percent change in MMDs across weeks 1-12 (PROMISE-1, odds ratio [OR]: 0.97, 95% confidence interval [CI]: 0.95, 0.98, p = 0.0001; PROMISE-2, OR: 0.94, CI: 0.92, 0.96, p < 0.0001) and change in 6-item Headache Impact Test (HIT-6) total score (PROMISE-2 only, OR: 0.92; CI: 0.87, 0.98; p = 0.027). In PROMISE-1, the probability of second-dose response ranged from 21.7% in patients with first-dose 0% MMD change to 56.0% in patients with first-dose 45% MMD reduction. In PROMISE-2, depending on HIT-6 total score, probability of second-dose response ranged from 5.9-12.1% in patients with first-dose 0% MMD change to 54.2%-72.3% in patients with first-dose 45.0% MMD reduction. CONCLUSION: Individuals with migraine not experiencing ≥50% MMD response to their first dose of eptinezumab may benefit from a second dose.

Inhibition of the Glycogen Synthase Kinase 3 Family by the Bikinin Alleviates the Long-Term Effects of Salinity in Barley.

Crops grown under stress conditions show restricted growth and, eventually, reduced yield. Among others, brassinosteroids (BRs) mitigate the effects of stress and improve plant growth. We used two barley cultivars with differing sensitivities to BRs, as determined by the lamina joint inclination test. Barley plants with the 2nd unfolded leaf were sprayed with a diluted series of bikinin, an inhibitor of the Glycogen Synthase Kinase 3 (GSK3) family, which controls the BR signaling pathway. Barley was grown under salt stress conditions up to the start of the 5th leaf growth stage. The phenotypical, molecular, and physiological changes were determined. Our results indicate that the salt tolerance of barley depends on its sensitivity to BRs. We confirmed that barley treatment with bikinin reduced the level of the phosphorylated form of HvBZR1, the activity of which is regulated by GSK3. The use of two barley varieties with different responses to salinity led to the identification of the role of BR signaling in photosynthesis activity. These results suggest that salinity reduces the expression of the genes controlling the BR signaling pathway. Moreover, the results also suggest that the functional analysis of the GSK3 family in stress responses can be a tool for plant breeding in order to improve crops' resistance to salinity or to other stresses.

Prognostic value of myometrial invasion and TCGA groups of endometrial carcinoma.

BACKGROUND: 2021 ESGO/ESTRO/ESP guidelines for the management of patients with endometrial carcinoma (EC) encourage molecular classification and propose a new prognostic risk stratification based on both pathologic and molecular features. Although deep myometrial invasion (DMI) has been considered as a crucial risk factor in EC, it is unclear if its prognostic value is independent from The Cancer Genome ATLAS (TCGA) groups. AIM: To assess if the prognostic value of DMI is independent from the TCGA groups in EC patients. MATERIALS AND METHODS: A systematic review and meta-analysis was performed by searching through 5 electronic databases, from their inception to March 2021, for all studies that allowed to assess DMI as a prognostic factor independent of the TCGA groups in EC patients. Pooled hazard ratio (HR) of DMI for overall survival (OS) and disease-free survival (DFS) was calculated at multivariable analyses including TCGA groups as a variable. Superficial myometrial invasion (<50% of myometrial thickness) was considered as a reference. In DFS analyses, locoregional and distant recurrence were separately considered for one study. RESULTS: Five studies with 2469 patients were included in the systematic review and 3 studies with 1549 patients in the meta-analysis. Pooled HR of DMI was 1.082 (CI 95% 0.85-1.377; p = 0.524) for OS, 1.709 (CI 95% 1.173-2.491; p = 0.005) for DFS, 1.585 (CI 95% 1.154-2.178; p = 0.004) for DFS additionally considering locoregional recurrence for one study, and 1.701 (CI 95% 1.235-2.344, p = 0.001) for DFS additionally considering distant recurrence for the same study. CONCLUSIONS: DMI does not appear as an independent prognostic factor for OS in EC patients; instead, it seems to affect the risk of recurrence independently from the TCGA groups. Further studies are necessary to confirm these findings and to assess the prognostic impact of DMI separately in each TCGA group.

Clear cell endometrial carcinomas with mismatch repair deficiency have a favorable prognosis: A systematic review and meta-analysis.

INTRODUCTION: In the ESGO/ESTRO/ESP guidelines for endometrial carcinoma management, the risk category of clear cell carcinoma (CCC) is not well defined. In fact, while p53-abnormal (p53abn) CCC are known to be aggressive, the prognosis of mismatch repair-deficient (MMRd) and p53-wild-type (p53wt) CCCs is less clear. OBJECTIVE: To assess the prognostic value of the MMRd and p53wt groups in CCC through a systematic review and meta-analysis. METHODS: Electronic databases were searched from their inception to February 2021. All studies reporting p53 expression, MMR proteins expression and survival outcomes in endometrial CCC (either pure or mixed) were included. Kaplan-Meier and Cox regression survival analyses with hazard ratio (HR) for overall survival (OS) were performed by using the p53abn group as reference; a significant p-value<0.05 was adopted. RESULTS: Six studies with 136 CCC (114 pure and 22 mixed) were included. Five-year OS was 95.7 ± 4.3% in the MMRd group, 48.4 ± 8.4% months in the p53wt group and 40.6 ± 10.4% in the p53abn group. The hazard of death was significantly lower in the MMRd group than in the p53abn group (HR = 0.062; p = 0.007), while it did not significantly differ between the p53wt and the p53abn group (HR = 0.673; p = 0.222). The POLEmut group could not be analyzed due to the absence of deaths. Similar results were observed in the pure CCC and mixed CCC subgroups. CONCLUSION: MMRd CCCs seem to have a favorable prognosis and might be lumped together with MMRd endometrioid carcinoma for management purpose. On the other hand, p53wt CCCs appear prognostically more similar to p53abn CCCs.

Tumor-infiltrating lymphocytes and POLE mutation in endometrial carcinoma.

BACKGROUND: Polymerase-ε (POLE)-mutated endometrial carcinomas (ECs) have displayed an increased number of tumor-infiltrating lymphocytes (TIL) compared to POLE-wild-type ECs. However, it is unclear if TIL may aid in identifying POLE-mutated ECs when molecular data are unavailable. The identification of a POLE mutation surrogate may be crucial to translate TCGA/ProMisE risk assessment in the clinical practice. AIM: To assess TIL as histological surrogate of POLE mutation in EC. MATERIALS AND METHODS: Seven electronic databases were searched from their inception to September 2020 for studies that allowed data extraction about TIL and TCGA/ProMisE groups of EC. We calculated pooled sensitivity, specificity, positive and negative likelihood ratios (LR+ and LR-), diagnostic odds ratio (DOR) and area under the curve (AUC) on SROC curves of TIL in distinguishing POLE-mutated from i) POLE-wild-type, ii) no specific molecular profile (NSMP), iii) POLE-wild-type/MMR-proficient, iii) MMR-deficient ECs. RESULTS: 10 studies assessing 1169 women were included in the qualitative analysis. TIL-high pattern showed: sensitivity = 0.65, specificity = 0.63, LR + =2.06, LR- = 0.48, DOR = 4.39, AUC = 0.7532 for POLE-mutant vs POLE-wild-type ECs; sensitivity = 0.85, specificity = 0.73, LR + =2.80, LR- = 0.22, DOR = 15.17 for POLE-mutant vs NSMP ECs; sensitivity = 0.85, specificity = 0.66, LR + =2.49, LR- = 0.25, DOR = 10.30 for POLE-mutant vs POLE-wild-type/MMR-proficient ECs; sensitivity = 0.68, specificity = 0.44, LR + =1.38, LR- = 0.64, DOR = 2.68, AUC = 0.6694 for POLE-mutant vs MMR-deficient ECs. CONCLUSION: TIL-high pattern shows a moderate accuracy in distinguishing POLE-mutated from POLE-wild-type ECs after the exclusion of MMR-deficient cases. TIL might be considered in an integrate algorithm to identify POLE-mutated ECs when sequencing is unavailable. Further studies are necessary in this regard.

Reliability and validity of the 6-item Headache Impact Test in chronic migraine from the PROMISE-2 study.

PURPOSE: We examined the reliability and validity of the 6-item Headache Impact Test (HIT-6) specifically on patients with chronic migraine (CM) from the PROMISE-2 clinical trial. METHODS: The conceptual framework of HIT-6 was evaluated using baseline data from the PROMISE-2 study (NCT02974153; N = 1072). A unidimensional graded response model within the item response theory (IRT) framework was used to evaluate model fit and item characteristics. Using baseline and week 12 data, convergent and discriminant validity of the HIT-6 was evaluated by correlation coefficients. Sensitivity to change was assessed by evaluating correlations between HIT-6 scores and change scores for other established reference measures. All examined correlations were specified a priori with respect to direction and magnitude. Known-groups analyses were anchored using Patient Global Impression of Change and monthly headache days at week 12. RESULTS: A unidimensional model fit the data well, supporting that the 6 items measure a single construct. All item slopes and thresholds were within acceptable ranges. In both the validity and sensitivity to change analyses, all observed correlations conformed to directional expectations, and most conformed to magnitude expectations. Known-groups analyses demonstrated that the HIT-6 total score can distinguish between clinically meaningful CM subgroups. CONCLUSION: The HIT-6 was successfully calibrated using IRT with data from PROMISE-2. Results from these analyses were generally consistent with previous literature and provided supportive evidence that the HIT-6 is well suited for measuring the impact of headache and migraine in the CM population.

Brassinazole Resistant 1 Activity Is Organ-Specific and Genotype-Dependent in Barley Seedlings.

Brassinosteroids (BRs) control many plant developmental processes by regulating different groups of transcription factors, and consequently gene expressions. The most known is BZR1, the main member of the BES1 family. However, to date, it is poorly characterized in crop species. The main goal of the presented study was to identify HvBZR1 and determine its activity in 5-day-old barley (the stage is related to one leaf on the main shoot and a few seminal roots) using two cultivars with different sensitivities to BRs. Using the anti-OsBZR1 antibody, we identified the forms of HvBZR1 transcription factor with different molecular weights, which can be related to different phosphorylated forms of serine/threonine residues. Two phosphorylated forms in the shoots and one dephosphorylated form in the roots were determined. A minor amount of the dephosphorylated form of the HvBZR1 in the Haruna Nijo shoots was also found. The phosphorylated forms gave a higher band intensity for Golden Promise than Haruna Nijo. The bands were similar in their intensity, when two different phosphorylated forms were compared in Golden Promise, while a reduced intensity was detected for the phosphorylated form with a lower molecular weight for Haruna Nijo. Degradation of the phosphorylated forms in the shoots (complete degradation in Golden Promise and significant but not complete in Haruna Nijo) and the presence of the dephosphorylated form in the roots were proven for the etiolated barley. In the case of Haruna Nijo, a wider range of the regulators of the BR biosynthesis and signaling pathways induced the expected effects, 24-EBL (0.001 µM) and bikinin (10 and 50 µM) caused low amount of the phosphorylated forms, and at the same time, a tiny band of dephosphorylated form was detected. However, the expression of genes related to the BR biosynthesis and signaling pathways was not a determinant for the protein amount.
