RESUMO

OBJECTIVE: Endometrial cancer (EndoCA) is the most common gynecologic cancer and incidence and mortality rate continue to increase. Despite well-characterized knowledge of EndoCA-defining mutations, no effective diagnostic or screening tests exist. To lay the foundation for testing development, our study focused on defining the prevalence of somatic mutations present in non-cancerous uterine tissue. METHODS: We obtained ≥8 uterine samplings, including separate endometrial and myometrial layers, from each of 22 women undergoing hysterectomy for non-cancer conditions. We ultra-deep sequenced (>2000× coverage) samples using a 125 cancer-relevant gene panel. RESULTS: All women harbored complex mutation patterns. In total, 308 somatic mutations were identified with mutant allele frequencies ranging up to 96.0%. These encompassed 56 unique mutations from 24 genes. The majority of samples possessed predicted functional cancer mutations but curiously no growth advantage over non-functional mutations was detected. Functional mutations were enriched with increasing patient age (p = 0.045) and BMI (p = 0.0007) and in endometrial versus myometrial layers (68% vs 39%, p = 0.0002). Finally, while the somatic mutation landscape shared similar mutation prevalence in key TCGA-defined EndoCA genes, notably PIK3CA, significant differences were identified, including NOTCH1 (77% vs 10%), PTEN (9% vs 61%), TP53 (0% vs 37%) and CTNNB1 (0% vs 26%). CONCLUSIONS: An important caveat for future liquid biopsy/DNA-based cancer diagnostics is the repertoire of shared and distinct mutation profiles between histologically unremarkable and EndoCA tissues. The lack of selection pressure between functional and non-functional mutations in histologically unremarkable uterine tissue may offer a glimpse into an unrecognized EndoCA protective mechanism.

RESUMO

Canonical NF-κB signaling through the inhibitor of κB kinase (IKK) complex requires induction of IKK2/IKKß subunit catalytic activity via specific phosphorylation within its activation loop. This process is known to be dependent upon the accessory ubiquitin (Ub)-binding subunit NF-κB essential modulator (NEMO)/IKKγ as well as poly-Ub chains. However, the mechanism through which poly-Ub binding serves to promote IKK catalytic activity is unclear. Here, we show that binding of NEMO/IKKγ to linear poly-Ub promotes a second interaction between NEMO/IKKγ and IKK2/IKKß, distinct from the well-characterized interaction of the NEMO/IKKγ N terminus to the "NEMO-binding domain" at the C terminus of IKK2/IKKß. We mapped the location of this second interaction to a stretch of roughly six amino acids immediately N-terminal to the zinc finger domain in human NEMO/IKKγ. We also showed that amino acid residues within this region of NEMO/IKKγ are necessary for binding to IKK2/IKKß through this secondary interaction in vitro and for full activation of IKK2/IKKß in cultured cells. Furthermore, we identified a docking site for this segment of NEMO/IKKγ on IKK2/IKKß within its scaffold-dimerization domain proximal to the kinase domain-Ub-like domain. Finally, we showed that a peptide derived from this region of NEMO/IKKγ is capable of interfering specifically with canonical NF-κB signaling in transfected cells. These in vitro biochemical and cell culture-based experiments suggest that, as a consequence of its association with linear poly-Ub, NEMO/IKKγ plays a direct role in priming IKK2/IKKß for phosphorylation and that this process can be inhibited to specifically disrupt canonical NF-κB signaling.

RESUMO

The 1969 White House Conference on Food, Nutrition, and Health had a significant influence on the direction of food and nutrition policy in the United States. The conference produced recommendations leading to federal legislation and programs to alleviate hunger and malnutrition, improve consumers' nutrition knowledge through education and labeling, and monitor the nutritional status of the population. Fifty years later, its legacy was revisited at a conference convened by Harvard University and Tufts University. This article reviews the literature contributing to the first author's keynote speech at the conference, its influencers, and its influences. We focus on the highlights of five domains that set the stage for the conference: the social environment, the food environment, nutrition science, public health data, and policy events. We briefly describe the conference, its proposed directions, and its lasting legacy in these five domains.

RESUMO

BACKGROUND: The coronavirus disease 2019 pandemic has resulted in unprecedented challenges for the oncology community. For people living with cancer, treatments are interrupted, surgeries cancelled, and regular oncology evaluations rescheduled. People with cancer and their physicians must balance plausible fears of coronavirus disease 2019 and cancer treatment with the consequences of delaying cancer care. OBJECTIVE: We aim to evaluate the experience of women with ovarian cancer during the coronavirus disease 2019 pandemic. STUDY DESIGN: Women with a current or previous diagnosis of ovarian cancer completed an online survey focusing on treatment interruptions and quality of life. The quality of life was measured with the Cancer Worry Scale and Hospital Anxiety and Depression Scale. The survey was distributed through survivor networks and social media. Univariate and multivariable linear regression analysis were used to evaluate the effect of participant characteristics on quality of life survey scores. RESULTS: A total of 603 women, from 41 states, visited the survey website between March 30, 2020, and April 13, 2020, and 555 (92.0%) completed the survey. The median age was 58 years (range, 20-85). At the time of survey completion, 217 participants (43.3%) were in active treatment. A total of 175 participants (33%) experienced a delay in some component of their cancer care. Ten (26.3%) of the 38 participants scheduled for surgery experienced a delay, as did 18 (8.3%) of the 217 participants scheduled for nonsurgical cancer treatment. A total of 133 participants (24.0%) had a delayed physician appointment, 84 (15.1%) laboratory tests, and 53 (9.6%) cancer-related imaging. Among the cohort, 88.6% (489) reported significant cancer worry, 51.4% (285) borderline or abnormal anxiety, and 26.5% (147) borderline or abnormal depression. On univariate analysis, age less than 65 years, being scheduled for cancer treatment or cancer surgery, delay in oncology care, being self-described as immunocompromised, and use of telemedicine were all associated with higher levels of cancer worry. Higher anxiety scores were associated with age less than 65 years and being self-described as immunocompromised. Higher depression scores were associated with age less than 65 years, being scheduled for cancer surgery, delay in oncology care, being self-described as immunocompromised, and use of telemedicine. On multivariable linear regression analysis, age less than 65 and being self-described as immunocompromised were independently predictive of greater cancer worry, anxiety, and depression, and delay in cancer care was predictive of anxiety and depression. CONCLUSION: The coronavirus disease 2019 crisis is affecting care of patients with ovarian cancer; surgeries, treatments, scheduled physician appointments, laboratory tests, and imaging are cancelled or delayed. Younger age, presumed immunocompromise, and delay in cancer care were associated with significantly higher levels of cancer worry, anxiety, and depression. Providers must work with patients to balance competing risks of coronavirus disease 2019 and cancer, recognizing that communication is a critical clinical tool to improve quality of life in these times.

RESUMO

Humans often say they prefer certain attributes and trait levels and yet choose options inconsistent with those preferences, a phenomenon known as the stated-revealed preference gap. In this article, we compare preferences and choices in the decision to adopt a dog, a social-choice problem that is largely one-sided. We used existing and newly gathered field data about the dog adoption process to study how people make their choices of companion animals and how those choices can be improved. We found that in the real-world choice of dogs within an animal shelter, individuals generally showed a large amount of overlap between their stated preferences and their ratings of the traits of their chosen dog. However, there was little relationship between an adopter's perceptions of their chosen dog's behavioral traits and third-party in-shelter behavior evaluations of the same dogs, suggesting that it is difficult to predict which dogs will satisfy an adopter's preferences. We also tested which commonly collected factors impact how quickly dogs are adopted from animal shelters. Overall, this work provides insight into the process of combining experimentally collected data and big data to elucidate choice behavior.

RESUMO

Online educational materials are largely disseminated through videos, and yet there is little understanding of how these videos engage students and fuel academic success. We hypothesized that components of the electroencephalogram (EEG), previously shown to reflect video engagement, would be predictive of academic performance in the context of educational videos. Two groups of subjects watched educational videos in either an intentional learning paradigm, in which they were aware of an upcoming test, or in an incidental learning paradigm, in which they were unaware that they would be tested. "Neural engagement" was quantified by the inter-subject correlation (ISC) of the EEG that was evoked by the videos. In both groups, students with higher neural engagement retained more information. Neural engagement also discriminated between attentive and inattentive video viewing. These results suggest that this EEG metric is a marker of the stimulus-related attentional mechanisms necessary to retain information. In the future, EEG may be used as a tool to design and assess online educational content.

RESUMO

BACKGROUND: Diltiazem (calcium channel blocker) and metoprolol (beta-blocker) are both commonly used to treat atrial fibrillation/flutter (AFF) in the emergency department (ED). However, there is considerable regional variability in emergency physician practice patterns and debate among physicians as to which agent is more effective. To date, only one small prospective, randomized trial has compared the effectiveness of diltiazem and metoprolol for rate control of AFF in the ED and concluded no difference in effectiveness between the two agents. OBJECTIVE: Our aim was to compare the effectiveness of diltiazem with metoprolol for rate control of AFF in the ED. METHODS: A convenience sample of adult patients presenting with rapid atrial fibrillation or flutter was randomly assigned to receive either diltiazem or metoprolol. The study team monitored each subject's systolic and diastolic blood pressures and heart rates for 30 min. RESULTS: In the first 5 min, 50.0% of the diltiazem group and 10.7% of the metoprolol group reached the target heart rate (HR) of <100 beats per minute (bpm) (p < 0.005). By 30 min, 95.8% of the diltiazem group and 46.4% of the metoprolol group reached the target HR < 100 bpm (p < 0.0001). Mean decrease in HR for the diltiazem group was more rapid and substantial than that of the metoprolol group. From a safety perspective, there was no difference between the groups with respect to hypotension (systolic blood pressure < 90 mm Hg) and bradycardia (HR < 60 bpm). CONCLUSIONS: Diltiazem was more effective in achieving rate control in ED patients with AFF and did so with no increased incidence of adverse effects.

RESUMO

PURPOSE: To assess pharmacists' and students' knowledge of high-dose insulin euglycemia (HIE) and intravenous fatty acid emulsion 20% (IFE) and to see whether it improved after an educational intervention. METHODS: A survey to assess the knowledge about the use of HIE and IFE as antidotes was e-mailed to practicing pharmacists, pharmacy residents, and students prior to and following an educational intervention. Fact sheets on the antidotes were developed in conjunction with the New York City Poison Control Center and were used as the educational intervention in this study. The impact of exposure to the intervention was measured by comparing the number of correct responses per question on the pre- and posttests and the mean pre- and posttest scores using chi-square and t tests, respectively. RESULTS: Most respondents felt either not at all or only somewhat comfortable with managing a toxicologic emergency. There was a statistically significant difference in mean scores on the pretest and posttest (2.9 vs 5.45; P = .001) and for the number of participants giving correct responses for each question before and after education: 52.4% of respondents answered "I don't know" to the questions prior to education versus 21.2% after education (P < .001). Fewer respondents felt not at all comfortable managing a toxicologic emergency after the educational intervention (42.4 vs 50.3%; P < .001). CONCLUSION: Pharmacists and students reported little comfort in managing toxicological emergencies in general and have limited baseline knowledge about these agents. Educational interventions can significantly improve knowledge. Prior familiarity with these newer antidotes should reduce delays in their administration in an emergency.

RESUMO

PURPOSE: To identify the subjective and objective characteristics that pharmacy residency programs use to define a successful resident and to determine what percentage of their 2009-2010 residency class they felt were successful. METHODS: An electronic survey was sent via e-mail to all residency program directors (RPDs) of postgraduate year 1 (PGY1) and postgraduate year 2 (PGY2) pharmacy residency programs in the United States. A 3-part survey instrument was developed following validation of questions for clarity and reliability using a pilot survey. Respondents were asked to rank the importance of 20 subjective characteristics for a resident to possess in order to be considered successful and the importance of different objective measurements of accomplishment in the definition of a "successful" resident using a Likert scale where 1 = not at all important, 2 = some importance, 3 = very important, and 4 = critical. RESULTS: Of the 1,081 surveys sent to RPDs, 473 respondents answered at least one question, yielding a response rate of 43.8%. The most critically important subjective characteristics in defining a successful resident as ranked among PGY1 residency programs are dependability, professionalism, self-motivation/initiative, and work ethic. PGY2 programs ranked clinical knowledge and skills, critical thinking, and dependability as the most important. The most critically important objective characteristic in defining a successful resident as ranked among both PGY1 and PGY2 programs is obtaining a clinical position. The majority of PGY1 and PGY2 respondents felt that 76% to 100% of their 2009-2010 residency class was successful based on the characteristics they rated most important. CONCLUSION: Identification of the characteristics that pharmacy residency programs use to define success will allow them to identify predictors of success and optimal methods of selecting residents who possess these characteristics.

RESUMO

OBJECTIVE: High-grade serous ovarian cancer (HGSOC) that is resistant to platinum-based chemotherapy has a particularly poor prognosis. Response to platinum has both prognostic survival value and dictates secondary treatment strategies. Using transcriptome analysis, we sought to identify differentially expressed genes/pathways based on a tumor's platinum response for discovering novel predictive biomarkers. METHODS: Seven primary HGSOC tumor samples, representing two extremes of platinum sensitivity/timing of disease recurrence, were analyzed by RNA-Seq, Ingenuity Pathways Analysis (IPA) and Upstream Regulator Analysis (URA), and used to explore differentially expressed genes and prevalent molecular and cellular processes. Progression-free and overall survival (PFS, OS) was estimated using the Kaplan-Meier method in two different sample sets including GEO and TCGA data sets. RESULTS: IPA and URA highlighted an IRF1-driven transcriptional program (P=0.0017; z-score of 3.091) in the platinum sensitive improved PFS group. QRT-PCR analysis of 31 HGSOC samples demonstrated a significant difference in PFS between low and high IRF1 expression groups (P=0.048) and between groups that were platinum sensitive versus not (P=0.016). In a larger validation data set, increased levels of IRF1 were associated with both increased PFS (P=0.043) and OS (P=0.019) and the effect on OS was independent of debulking status (optimal debulking, P=0.025; suboptimal, P=0.041). CONCLUSION: Transcriptome analysis identifies IRF1, a transcription factor that functions both in immune regulation and as a tumor suppressor, as being associated with platinum sensitivity and an independent predictor of both PFS and OS in HGSOC.

RESUMO

Objective: National data have shown worse endometrial cancer (EC) outcomes among racial and ethnic minorities. We aimed to analyze EC patient outcomes within a large urban academic health system, with a focus on patterns of care and recurrence rates. Methods: This was a retrospective chart review of EC patients at three system hospitals from 1/1/07-12/31/17. Demographic and clinical factors, including time from EMB to surgery, rate of chemotherapy completion, persistent or recurrent disease, and palliative care referrals were extracted. Descriptive statistics and survival curves were generated. Analysis was done using SAS version 9.4. Results: Black patients had lower overall survival compared to all others on univariate analysis only (p < 0.0001). Hospital site was associated with OS, with the academic anchor and satellite 1 having higher rates of all-cause mortality compared to satellite 2 (HR 4.68 academic anchor, 95 % CI 1.72-12.76, HR 5.36 satellite 1, 95 % CI 1.85-15.52). Time from EMB to surgery and rates of persistent disease following primary treatment were higher in Black patients. After adjusting for stage and grade, chemotherapy completion rate was significantly associated with race. Palliative care was utilized more for Black than White patients after adjusting for stage and grade (p = 0.005). Conclusions: Racial disparities in EC are caused by a complex web of interconnected factors that ultimately lead to worse outcomes in Black women. While precision medicine has helped to close the gap, social determinants of health should be addressed, and models focusing on the complex interactions between biologic, genetic, and social factors should be utilized.

RESUMO

BACKGROUND: From September 2002 to August 2010, 13 patients who were discharged from the emergency department (ED) were immunized against influenza. This correlates with a time when pharmacists were not permitted to vaccinate patients in New York. OBJECTIVE: The objectives of this study were to determine the feasibility of a pharmacist-based influenza vaccination program in the ED, assess patients' willingness to be vaccinated by a pharmacist, and identify reasons for declination. METHODS: This was a cross-sectional study involving English-speaking patients older than 18 years. The pharmacist vaccinated patients, if they consented. Patients who refused to be vaccinated were asked why they did not want to receive the vaccine and their perception of pharmacists vaccinating patients in the ED. The percentage of patients vaccinated; time elements associated with the process of screening, counseling, and vaccinating; and the type and frequency of adverse events were recorded. RESULTS: Of 149 patients, 62 patients (41%) agreed to receive the vaccine, a 4-fold increase from the previous 8 years. The median screening and vaccination time was 8 minutes. Of those not receiving a vaccine in the ED, 74% were willing to receive the influenza vaccine from a pharmacist, and 78% were willing to receive the vaccine in the ED. The most common reason for refusal was perception of low self-risk (43.9%). No adverse events were reported. CONCLUSIONS: A pharmacist-based influenza immunization program is feasible in the ED and has the potential to successfully and safely increase the percentage of adult patients receiving the vaccine.

RESUMO

OBJECTIVE: The primary goal of this study is to examine disparities in high-risk endometrial cancer (EC) patients in relation to rates of genetic referrals (GR), testing (GT), and counseling (GC). METHODS: This is a retrospective analysis of patients with newly diagnosed EC between January 1, 2014 and September 1, 2020 at a single institution. Patients were defined as high-risk EC patients when they were 1) diagnosed at 50 years or younger, 2) had a positive family history for cancer or 3) had evidence of loss of mismatch repair protein expression on tumor immunohistochemistry. Rates of GR, GT and GC were analyzed based on race, ethnicity, primary language and insurance status. RESULTS: During the study period, 674 patients were diagnosed with EC and 249 (36.9%) were considered high-risk EC patients. Among high-risk patients, 128 (51.2%) were referred to GT and GC. Of those referred, 103 (80.5%) underwent GT and 85 (66.4%) completed GC. Out of all high-risk patients, 20 (18.4%) were positive for LS on GT and 29 (28.2%) had VUS results. In multivariate analysis, the odds of GT and GC referral were lower among patients who identified as Hispanic (OR=0.40; 95% CI=0.19-0.87; p=0.020). Patients who identified as black were less likely to receive GC when compared to patients of other races (p=0.030). CONCLUSION: It is our hope that through this data we will increase awareness around existing disparities in genetic evaluation for patients with EC and ultimately create strategies to improve equitable access to care for all patients.

RESUMO

Elevated ß oscillations (13-35 Hz) are characteristic pathophysiology in Parkinson's Disease (PD). Cortical thinning has also been reported in the disease, however the relationship between these biomarkers of PD has not been established. By comparing electrophysiological measurements with cortical thickness, this study aims to reveal the pathoetiology of disease and symptoms in PD. Preoperative magnetic resonance imaging (MRI) and intraoperative local field potentials (LFPs) were collected from 34 subjects diagnosed with PD. Cortical surfaces were reconstructed from the images, and cortical thickness was extracted from the subregions where the recording electrode was placed in M1. LFPs were preprocessed and cleaned using a semiautomatic artifact detection algorithm, then power spectral densities (PSD) were computed and periodic and aperiodic frequency components were calculated. Nonparametric Spearman rank correlations assessed the relationship between electrophysiological components (i.e. center frequency (CF), power, bandwidth, 1/f exponent, knee), with cortical thickness. According to the CF of each subject's PSD, the cohort was split into two sub-groups: low-ß peak (13-20 Hz) and high-ß peak (20-35 Hz) groups. There was a significant negative correlation between power and cortical thickness only in the high-ß subgroup (r=-0.48, p(corrected)=0.049). This relationship remained significant when correcting for age (r=-0.52,p=0.015), indicating that the effect of age on cortical thinning was not the determining factor. We did not find significant differences between UPDRS-III motor symptom scores for the low-and high-ß subgroups. Of note is the dominance of high-ß oscillatory power and its relationship with cortical thickness. As suggested by the literature, increased high-ß activity during movement may be exaggerated in PD. These findings suggest that the characteristic cortical thinning in PD causes variation in electrical activity, leading to elevated high-ß activity.Clinical relevance- This multimodal study provides additional insights on the pathophysiology and its relevance with morphology of Parkinson's Disease.

RESUMO

As data sharing has become more prevalent, three pillars - archives, standards, and analysis tools - have emerged as critical components in facilitating effective data sharing and collaboration. This paper compares four freely available intracranial neuroelectrophysiology data repositories: Data Archive for the BRAIN Initiative (DABI), Distributed Archives for Neurophysiology Data Integration (DANDI), OpenNeuro, and Brain-CODE. The aim of this review is to describe archives that provide researchers with tools to store, share, and reanalyze both human and non-human neurophysiology data based on criteria that are of interest to the neuroscientific community. The Brain Imaging Data Structure (BIDS) and Neurodata Without Borders (NWB) are utilized by these archives to make data more accessible to researchers by implementing a common standard.

RESUMO

As data sharing has become more prevalent, three pillars - archives, standards, and analysis tools - have emerged as critical components in facilitating effective data sharing and collaboration. This paper compares four freely available intracranial neuroelectrophysiology data repositories: Data Archive for the BRAIN Initiative (DABI), Distributed Archives for Neurophysiology Data Integration (DANDI), OpenNeuro, and Brain-CODE. The aim of this review is to describe archives that provide researchers with tools to store, share, and reanalyze both human and non-human neurophysiology data based on criteria that are of interest to the neuroscientific community. The Brain Imaging Data Structure (BIDS) and Neurodata Without Borders (NWB) are utilized by these archives to make data more accessible to researchers by implementing a common standard. As the necessity for integrating large-scale analysis into data repository platforms continues to grow within the neuroscientific community, this article will highlight the various analytical and customizable tools developed within the chosen archives that may advance the field of neuroinformatics.
