- Abstract
La mastocytose systémique indolente (MSI), maladie clonale des mastocytes principalement induite par la mutation D816V du gène KIT, s’accompagne de symptômes invalidants à long terme, dont une anaphylaxie pouvant mettre la vie en danger, mais aussi une mauvaise qualité de vie (QdV) et une morbidité significative. La plupart des patients reçoivent des traitements axés sur les symptômes qui s’avèrent souvent inefficaces. L’avapritinib, un inhibiteur oral, puissant et sélectif de la mutation D816V de KIT, est le premier et le seul traitement approuvé pour les patients adultes atteints de MSI dans l’UE et aux États-Unis.

Магистерская диссертация состоит из введения, обзора литературы, описания материалов и методов, результатов и их обсуждений, выводов и списка литературы. Материалы работы изложены на 75 страницах (основного текста). Работа содержит 3 таблицу, 104 рисунка, 2 приложения. Список литературы включает 104 источника, из которых 19 отечественных и 85 иностранных. Цель исследования: Выявить диагностическую роль анатомо-морфологических и эколого-биологических признаков отдельных представителей рода Begonia L., культивируемых на кафедре биоразнообразия и биоэкологи ИЕНиМ УрФУ и в оранжереях Ботанического сада УрФУ и УрО РАН. Объектами исследования являются виды и культивары рода Begonia L., выращиваемых на кафедре биоразнообразия и биоэкологии ИЕНиМ УрФУ и в оранжереях Ботанических садов УрФУ и УрО РАН. В работе изучались анатомо-морфологические характеристики видов и культиваров, состоящие в 8 разных секциях: Begonia, Diploclinium, Gaerdtia, Gireoudia, Knesebeckia, Platycentrum, Pritzelia, Weilbachia. Актуальностью настоящей работы является изучение видов и культиваров рода Begonia L., так как группа является крайне разнородной и уникальной, обладающая важным экономическим потенциалом. Представители данного рода могут стать одними из модельных объектов для изучения биоразнообразия и развития подходов для его сохранения. Важным является и то, что в исследования необходимо вовлекать не только дикорастущие виды, но и огромный объем культиваров, входящие в этот род. Также согласно современным исследованиям, бегонии имеют потенциал растений, обладающими лекарственными свойствами, что крайне важно для будущих и возможных фармацевтических исследований и создания медицинских препаратов. В результате проведенных исследований, на основании изученых анатомо-морфологических характеристик таксонов, были выявлены диагностические признаки 8 секций и проведен анализ соотношения выявленных признаков с эколого-биологическими особенностями представителей рода Begonia L. Master's dissertation consists of an introduction, a literature review, a description of materials and methods, results and their discussions, conclusions, and a list of references. The materials of the work are presented on 75 pages (main text). The work contains 3 tables, 104 figures, 2 appendices. The list of references includes 104 sources, of which 19 are domestic and 85 are foreign. Purpose of the study: To reveal the diagnostic role of anatomical-morphological and ecological-biological characters of individual representatives of the genus Begonia L. cultivated at the Department of Biodiversity and Bioecology of the Institute of Natural Sciences and Metrology of the UrFU and in the greenhouses of the Botanical Garden of the Ural Federal University and the Ural Branch of the Russian Academy of Sciences. The objects of research are the species and cultivars of the genus Begonia L. grown at the Department of Biodiversity and Bioecology of the Institute of Natural Sciences and Mathematics of the Ural Federal University and in the greenhouses of the Botanical Gardens of the Ural Federal University and the Ural Branch of the Russian Academy of Sciences. The work studied the anatomical and morphological characteristics of species and cultivars, consisting of 8 different sections: Begonia, Diploclinium, Gaerdtia, Gireoudia, Knesebeckia, Platycentrum, Pritzelia, Weilbachia The relevance of this work is the study of species and cultivars of the genus Begonia L., since the group is extremely diverse and unique, with important economic potential. Representatives of this genus can become one of the model objects for studying biodiversity and developing approaches for its conservation. It is also important that research should involve not only wild-growing species but also a huge volume of cultivars belonging to this genus. Also, according to modern research, begonias have the potential of plants with medicinal properties, which is extremely important for future and possible pharmaceutical research and the creation of medicines. As a result of the studies carried out, on the basis of the studied anatomical and morphological characteristics of taxa, diagnostic features of 8 sections were identified, and the analysis of the correlation of the identified characters with the ecological and biological characteristics of representatives of the genus Begonia L.

In this talk, we revisit the classical Muntz-Szasz approximation theorem and some of its proofs. We consider certain Lipschitz curves in the complex domain on which analogous results hold. We discuss related results on zeros and growth of Laplace transforms along these curves, and we consider the connection with the problem of quasi-analyticity on curves.

- Abstract
Contains fulltext : 118242.pdf (publisher's version ) (Open Access), BACKGROUND: Gene-based vaccination using prime/boost regimens protects animals and humans against malaria, inducing cell-mediated responses that in animal models target liver stage malaria parasites. We tested a DNA prime/adenovirus boost malaria vaccine in a Phase 1 clinical trial with controlled human malaria infection. METHODOLOGY/PRINCIPAL FINDINGS: The vaccine regimen was three monthly doses of two DNA plasmids (DNA) followed four months later by a single boost with two non-replicating human serotype 5 adenovirus vectors (Ad). The constructs encoded genes expressing P. falciparum circumsporozoite protein (CSP) and apical membrane antigen-1 (AMA1). The regimen was safe and well-tolerated, with mostly mild adverse events that occurred at the site of injection. Only one AE (diarrhea), possibly related to immunization, was severe (Grade 3), preventing daily activities. Four weeks after the Ad boost, 15 study subjects were challenged with P. falciparum sporozoites by mosquito bite, and four (27%) were sterilely protected. Antibody responses by ELISA rose after Ad boost but were low (CSP geometric mean titer 210, range 44-817; AMA1 geometric mean micrograms/milliliter 11.9, range 1.5-102) and were not associated with protection. Ex vivo IFN-gamma ELISpot responses after Ad boost were modest (CSP geometric mean spot forming cells/million peripheral blood mononuclear cells 86, range 13-408; AMA1 348, range 88-1270) and were highest in three protected subjects. ELISpot responses to AMA1 were significantly associated with protection (p = 0.019). Flow cytometry identified predominant IFN-gamma mono-secreting CD8+ T cell responses in three protected subjects. No subjects with high pre-existing anti-Ad5 neutralizing antibodies were protected but the association was not statistically significant. SIGNIFICANCE: The DNA/Ad regimen provided the highest sterile immunity achieved against malaria following immunization with a gene-based subunit vaccine (27%). Protection was associ

In dark skinned subjects, delayed or " secondary" pigmentation from ultra-violet light may be the only clinical sign of sunburn. It results from necrobiosis limited to the outer Malpighian layer and hardly extends deeper than this even when the dose exceeds the maximum possible from a day's natural sunshine. Preceding erythema is not merely masked by the pigment, but is often virtually absent. On the background of this natural skin resistance, the hyperkeratotic pellagrous lesion is interpreted as a marked reaction to mild or repeated ultraviolet injury followed by retention and ultimate cracking of the abnormal layers so produced. These layers are formed below the normal stratum granulosum when the initial damage is severe, but lie above the new stratum granulosum which forms underneath as the cells keratinize.

- Abstract
Myeloproliferative neoplasms (MPNs) are a group of rare chronic progressive blood cancers that vary widely in clinical presentation, yet all patients have a risk of disease progression and thrombotic complications. Diseases include primary myelofibrosis, polycythemia vera, and essential thrombocythemia. With current treatment approaches, most patients live a prolonged life, but many experience a complex of symptoms that negatively influence their functional status and quality of life. Although significant advances have been made in preventing arterial and venous complications while mitigating inflammatory processes, comprehensive palliative care can help address unmet complex physical and psychosocial needs on a long-term basis. This article, created by a multidisciplinary group of providers, offers an overview of MPNs so palliative care clinicians can better support patients with these hematologic cancers.

- Abstract
Peer mentorship shows promise as a strategy to support veteran mental health. A community-academic partnership involving a veteran-led nonprofit organization and institutions of higher education evaluated a collaboratively developed peer mentor intervention. We assessed posttraumatic stress disorder (PTSD), postdeployment experiences, social functioning, and psychological strengths at baseline, midpoint, and 12-week discharge using the PTSD Checklist for DSM-5 (PCL-5), Deployment Risk and Resilience Inventory-2, Social Adaptation Self-evaluation Scale, and Values in Action Survey. Brief weekly check-in surveys reinforced mentor contact and assessed retention. The sample included 307 veterans who were served by 17 veteran peer mentors. Mixed-effects linear models found a modest effect for PTSD symptom change, with a mean PCL-5 score reduction of 4.04 points, 95% CI [-6.44, -1.64], d = 0.44. More symptomatic veterans showed a larger effect, with average reductions of 9.03 points, 95% CI [-12.11, -5.95], d = 0.77. There were no significant findings for other outcome variables. Compared to younger veterans, those aged 32-57 years were less likely to drop out by 6 weeks, aORs = 0.32-0.26. Week-by-week hazard of drop-out was lower with mentors ≥ 35 years old, aHR = 0.62, 95% CI [0.37, 1.05]. Unadjusted survival differed by mentor military branch, p = .028, but the small mentor sample reduced interpretability. Like many community research efforts, this study lacked a control group, limiting the inferences that can be drawn. Continued study of veteran peer mentorship is important as this modality is often viewed as more tolerable than therapy., (© 2024 International Society for Traumatic Stress Studies.)

- Abstract
Mastocytosis is a heterogeneous group of disorders comprising cutaneous mastocytosis, systemic mastocytosis, and mast cell sarcoma. It is associated with a variety of symptoms related to the release of mast cell mediators and mast cell tissue infiltration. Referral to specialized centers with expertise in the management of mastocytosis and multidisciplinary collaboration with subspecialists (eg, allergists for the management of anaphylaxis and drug hypersensitivities, anesthesiologists for invasive procedures or surgery, high-risk obstetrician for pregnancy) is recommended. The NCCN Guidelines for Systemic Mastocytosis provide evidence- and consensus-based recommendations for the diagnosis and comprehensive care of patients with systemic mastocytosis. The multidisciplinary panel of experts convenes at least once a year to review requested changes to the guidelines from both internal and external entities as well as to discuss data on existing and new therapies. These NCCN Guidelines Insights focus on some of the recent updates to the guidelines.

- Abstract
Objectives: To evaluate the safety of cangrelor administered concurrently with heparin or bivalirudin in patients on mechanical circulatory support., Design: A single-center, retrospective cohort study of adult patients consecutively admitted between January 2016 and October 2020., Setting: A tertiary medical center., Participants: Adult patients admitted to the cardiovascular intensive care unit put on mechanical circulatory support for acute myocardial infarction (AMI) or non-AMI indications. Patients who received cangrelor underwent percutaneous coronary intervention with stenting during the index event or within the last year., Interventions: None., Measurements and Main Results: The primary outcome was the incidence of major bleeding, defined by the Extracorporeal Life Support Organization criteria, in patients with mechanical circulatory support receiving cangrelor plus anticoagulation with heparin or bivalirudin with or without aspirin versus patients who did not receive cangrelor. Sixty-eight patients were included in the study. Twenty-nine patients received cangrelor, and 39 did not. Cangrelor was not associated with an increase in major bleeding; however, the CI was wide (adjusted hazard ratio 1.93, 95% CI 0.61-6.11; p = 0.262)., Conclusions: Patients receiving cangrelor did not appear to be at higher risk of major bleeding compared to patients not receiving cangrelor. Larger trials should be conducted to better evaluate the safety of cangrelor in patients with mechanical circulatory support., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Inc.

- Abstract
Current prostate carcinoma (PCa) biomarkers, including total prostate-specific antigen (tPSA), have unsatisfactory diagnostic sensitivity and specificity resulting in overdiagnosis and overtreatment. Previously, we described an optimised bias-based preamplification-digital droplet PCR (OBBPA-ddPCR) technique, which detects tumour DNA in blood-derived cell-free DNA (cfDNA) of cancer patients. The current study investigated the performance of newly developed OBBPA-ddPCR-based biomarkers. Blood plasma samples from healthy individuals ( n = 90, controls) and PCa ( n = 39) and benign prostatic hyperplasia patients (BPH, n = 40) were analysed. PCa and BPH patients had tPSA values within a diagnostic grey area of 2-15 ng/mL, for whom further diagnostic validation is most crucial. Methylation levels of biomarkers RASSF1A , MIR129-2 , NRIP3 , and SOX8 were found significantly increased in PCa patients compared to controls. By combining classical PCa risk factors (percentage of free PSA compared to tPSA (QfPSA) and patient's age) with cfDNA-based biomarkers, we developed PCa risk scores with improved sensitivity and specificity compared to established tPSA and QfPSA single-marker analyses. The diagnostic specificity was increased to 70% with 100% sensitivity for clinically significant PCa patients. Thus, prostate biopsies could be avoided for 28 out of 40 BPH patients. In conclusion, the newly developed risk scores may help to confirm the clinical decision and prevent unnecessary prostate biopsy., Competing Interests: The authors declare no conflicts of interest. The funding body had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, or in the decision to publish the results.

Study Objective: Enoxaparin is standard of care for venous thromboembolism (VTE) prophylaxis in adult trauma patients, but fixed-dose protocols are suboptimal. Dosing based on body mass index (BMI) or total body weight (TBW) improves target prophylactic anti-Xa level attainment and reduces VTE rates. A novel strategy using estimated blood volume (EBV) may be more effective based on results of a single-center study. This study compared BMI-, TBW-, EBV-based, and hybrid enoxaparin dosing strategies at achieving target prophylactic anti-Factor Xa (anti-Xa) levels in trauma patients., Design: Multicenter, retrospective review., Data Source: Electronic health records from participating institutions., Patients: Adult trauma patients who received enoxaparin twice daily for VTE prophylaxis and had at least one appropriately timed anti-Xa level (collected 3 to 6 hours after the previous dose after three consecutive doses) from January 2017 through December 2020. Patients were excluded if the hospital-specific dosing protocol was not followed or if they had thermal burns with > 20% body surface area involvement., Intervention: Dosing strategy used to determine initial prophylactic dose of enoxaparin., Measurements: The primary end point was percentage of patients with peak anti-Xa levels within the target prophylactic range (0.2-0.4 units/mL)., Main Results: Nine hospitals enrolled 742 unique patients. The most common dosing strategy was based on BMI (43.0%), followed by EBV (29.0%). Patients dosed using EBV had the highest percentage of target anti-Xa levels (72.1%). Multiple logistic regression demonstrated EBV-based dosing was significantly more likely to yield anti-Xa levels at or above target compared to BMI-based dosing (adjusted odds ratio (aOR) 3.59, 95% confidence interval (CI) 2.29-5.62, p < 0.001). EBV-based dosing was also more likely than hybrid dosing to yield an anti-Xa level at or above target (aOR 2.30, 95% CI 1.33-3.98, p = 0.003). Other pairwise comparisons between dosing strategy groups were nonsignificant., Conclusions: An EBV-based dosing strategy was associated with higher odds of achieving anti-Xa level within target range for enoxaparin VTE prophylaxis compared to BMI-based dosing and may be a preferred method for VTE prophylaxis in adult trauma patients., (© 2023 Pharmacotherapy Publications, Inc.)

- Abstract
Background: The optimal dosing for enoxaparin venous thromboembolism (VTE) prophylaxis in low-weight trauma patients is unknown. Estimated blood volume (EBV) has shown promise as a dose modifier., Objective: To characterize the association of enoxaparin dose per EBV with the prevalence of VTE and bleeding in low-weight trauma patients., Methods: This was a retrospective study of trauma patients admitted over a 4-year period. Included patients were adults weighing <60 kg who received a minimum of 3 consecutive doses of enoxaparin. The primary endpoint was a comparison of enoxaparin dose per EBV in patients experiencing bleeding and VTE. Secondary endpoints included comparisons of dose per body mass index (BMI) and total body weight (TBW) and the ability of dose per EBV to predict clinical endpoints. Subgroup analyses for patients weighing <50 kg were performed for all endpoints., Results: A total of 189 patients were included. Statistical comparisons for VTE were not performed because of low prevalence. The dose of enoxaparin per EBV was not statistically different between patients who did and did not bleed in all analyses. Doses per BMI and TBW were also not statistically different between the groups. In patients weighing <50 kg, numerically higher doses per EBV, BMI, and TBW were noted in patients that bled versus those that did not. Enoxaparin dose per EBV was not a statistically significant predictor of bleeding in logistic regression models., Conclusion and Relevance: No significant associations between enoxaparin dose per EBV, BMI, or TBW and bleeding were noted in the study. Future analyses of EBV and other dose modifiers should consider inclusion of patients weighing <50 kg., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Purpose: Fixed-dose and body mass index (BMI)-based enoxaparin regimens provide inadequate venous thromboembolism (VTE) prophylaxis for many trauma patients. The purpose of this study was to evaluate the effectiveness of a novel blood volume (BV)-based enoxaparin guideline vs a historical BMI-based guideline for VTE prophylaxis in trauma patients., Methods: This was a retrospective pre/post study completed at a large academic level 1 trauma center. All adult trauma patients admitted from October through December 2019 and August through October 2020 who received prophylactic enoxaparin per guideline were included. The BV dosing was as follows: patients with a BV of 3 to 4.9 L received enoxaparin 30 mg every 12 hours, those with a BV of 5 to 6.9 L received 40 mg every 12 hours, and those with a BV of ≥7 L received 60 mg every 12 hours. The primary outcome was the percentage of patients who attained a target anti-factor Xa (anti-Xa) postdosing level at the first steady-state assessment (0.2 to 0.5 IU/mL)., Results: A total of 241 patients (99 for the BMI group and 142 for the BV group) were included. The study groups had a median age of 38 vs 42 years, a mean BMI of 27.4 vs 27.7 kg/m2, and a mean BV of 5.1 vs 5.1 L, respectively. A total of 63 patients (62.6%) in the BMI group attained target anti-Xa levels compared to 115 patients (81%) in the BV group (P = 0.008). In multivariate regression, the BV-based guideline was the only variable associated with attainment of target anti-Xa levels (adjusted odds ratio, 2.02; P = 0.01). Clinically relevant bleeding and VTE rates were similar between the groups., Conclusion: Dosing prophylactic enoxaparin using a BV-based dosing guideline significantly increased attainment of target anti-Xa levels., (© American Society of Health-System Pharmacists 2023.

- Abstract
Introduction: Enoxaparin is administered for venous thromboembolic (VTE) prophylaxis in bariatric surgery patients. There is concern whether body mass index (BMI)-based enoxaparin dosing consistently achieves prophylactic targets in patients with severe obesity., Methods: This retrospective study included patients who underwent bariatric surgery at an academic medical center from Jan 2015-May 2021 and had an anti-Xa level drawn 2.5-6 h after ≥3 doses of BMI-based prophylactic enoxaparin. The primary outcome was the percentage of patients who achieved a target anti-Xa level. Secondary outcomes were prevalence of venous thromboembolic and bleeding events within 30 d post-operatively., Results: Overall, 137 patients were included. Mean BMI was 59.1 ± 10.4 kg/m
2 , mean age was 43.9 ± 13.3 y and 110 patients (80.3%) were female. Target anti-Xa levels were achieved in 116 patients (84.7%); 14 (10.2%) were above target and 7 (5.1%) were below target. Patients with above target anti-Xa levels were significantly shorter in height than those within target range (167.1 versus 159.8 cm, P = 0.003). Five patients (3.6%) had a bleeding event; no thromboembolisms occurred. Anti-Xa levels correlated more strongly with enoxaparin dose per unit estimated blood volume (EBV) than dose per unit BMI (Rho = 0.54 versus Rho = 0.33)., Conclusions: Target range anti-Xa levels were achieved in 85% of patients using BMI-based enoxaparin dosing. Patients with above target anti-Xa levels were significantly shorter by nearly 3 inches, suggesting an increased risk of overdosing enoxaparin in shorter, obese patients. An EBV-based dosing regimen may better account for patient height and is supported by a greater correlation with anti-Xa levels with dosing based on EBV than BMI., (Copyright © 2023 Elsevier Inc.

- Abstract
BACKGROUND: Indolent systemic mastocytosis (ISM) is a clonal mast-cell disease driven by the KIT D816V mutation. We assessed the efficacy and safety of avapritinib versus placebo, both with best supportive care, in patients with ISM. METHODS: We randomized patients with moderate to severe ISM (total symptom score [TSS] of ≥28; scores range from 0 to 110, with higher numbers indicating more severe symptoms) two to one to avapritinib 25 mg once daily (n=141) or placebo (n=71). The primary end point was mean change in TSS based on the 14-day average of patient-reported severity of 11 symptoms. Secondary end points included reductions in serum tryptase and blood KIT D816V variant allele fraction (≥50%), reductions in TSS (≥50% and ≥30%), reduction in bone marrow mast cells (≥50%), and quality of life measures. RESULTS: From baseline to week 24, avapritinib-treated patients had a decrease of 15.6 points (95% CI, −18.6 to −12.6) in TSS compared to a decrease of 9.2 points (−13.1 to −5.2) in the placebo group; P<0.003. From baseline to Week 24, 76/141 patients (54%; 45% to 62%) in the avapritinib group compared to 0/71 patients in the placebo group achieved a ≥50% reduction in serum tryptase level; P<0.001. Edema and increases in alkaline phosphatase were more common with avapritinib than placebo; there were few treatment discontinuations because of adverse events. CONCLUSIONS: In this trial, avapritinib was superior to placebo in reducing uncontrolled symptoms and mast-cell burden in patients with ISM. The long-term safety and efficacy of this approach for patients with ISM remain the focus of the ongoing trial. (Funded by Blueprint Medicines Corporation; ClinicalTrials.gov number, NCT03731260.)

- Abstract
Objectives: Evaluate the safety and efficacy of the Janus kinase (JAK)1/JAK2 inhibitor ruxolitinib in COVID-19-associated acute respiratory distress syndrome requiring mechanical ventilation., Design: Phase 3 randomized, double-blind, placebo-controlled trial Ruxolitinib in Participants With COVID-19-Associated Acute Respiratory Distress Syndrome Who Require Mechanical Ventilation (RUXCOVID-DEVENT; NCT04377620)., Setting: Hospitals and community-based private or group practices in the United States (29 sites) and Russia (4 sites)., Patients: Eligible patients were greater than or equal to 12 years old, hospitalized with severe acute respiratory syndrome coronavirus 2 infection, and mechanically ventilated with a Pa o2 /F io2 of less than or equal to 300 mm Hg within 6 hours of randomization., Interventions: Patients were randomized 2:2:1 to receive twice-daily ruxolitinib 15 mg, ruxolitinib 5 mg, or placebo, each plus standard therapy., Measurements and Main Results: The primary endpoint, 28-day mortality, was tested for each ruxolitinib group versus placebo using a mixed-effects logistic regression model and one-tailed significance test (significance threshold: p < 0.025); no type 1 error was allocated to secondary endpoints. Between May 24, 2020 and December 15, 2020, 211 patients (age range, 24-87 yr) were randomized (ruxolitinib 15/5 mg, n = 77/87; placebo, n = 47). Acute respiratory distress syndrome was categorized as severe in 27% of patients (58/211) at randomization; 90% (190/211) received concomitant steroids. Day-28 mortality was 51% (39/77; 95% CI, 39-62%) for ruxolitinib 15 mg, 53% (45/85; 95% CI, 42-64%) for ruxolitinib 5 mg, and 70% (33/47; 95% CI, 55-83%) for placebo. Neither ruxolitinib 15 mg (odds ratio, 0.46 [95% CI, 0.201-1.028]; one-sided p = 0.029) nor 5 mg (odds ratio, 0.42 [95% CI, 0.171-1.023]; one-sided p = 0.028) significantly reduced 28-day mortality versus placebo. Numerical improvements with ruxolitinib 15 mg versus placebo were observed in secondary outcomes including ventilator-, ICU-, and vasopressor-free days. Rates of overall and serious treatment-emergent adverse events were similar across treatments., Conclusions: The observed reduction in 28-day mortality rate between ruxolitinib and placebo in mechanically ventilated patients with COVID-19-associated acute respiratory distress syndrome was not statistically significant; however, the trial was underpowered owing to early termination., Competing Interests: Dr. Rein disclosed that she served as a consultant for AbbVie, Blueprint Medicines, Celgene, CTI BioPharma, and Novartis and as a site principal investigator on clinical trials involving ruxolitinib.

- Abstract
Objectives: Healthcare delivery is heterogenous; the reasons for this are numerous and complex. Patient-specific factors including geography, income, insurance status, age, and gender have been shown to bias surgical outcomes. Utilizing a prospectively collected all-payer database, we aim to evaluate the influence of socioeconomic factors on mortality and length of stay (LOS) after common cardiac surgical procedures., Methods: We utilized the National Inpatient Sample, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality for the year 2019. We included patients undergoing coronary artery bypass grafting (CABG), aortic valve replacement (AVR), transcatheter aortic valve replacement (TAVR), and combined AVR/CABG using the 10th revision of the International Classification of Diseases procedure codes. AVR and CABG were combined into a separate cohort as this was felt to represent a different pathology than isolated valvular or coronary arterial disease. Baseline demographics were summarized. Multivariable regression was performed within each procedure group to model the odds of in-hospital mortality and hospital LOS with age, sex, insurance, zip-code median household income, and location as predictors., Results: Baseline patient characteristics including gender, income, geography, and payer status were similar between CABG, AVR, and AVR/CABG. TAVR patients had a higher proportion of female sex and Medicare as the primary payer, with an overall greater age. Multivariable Cox proportional hazards regression found that higher income was strongly associated with decreased LOS following AVR and CABG, and moderately associated in TAVR and AVR/CABG. Private insurance was associated with a decreased LOS in patients undergoing CABG, AVR, TAVR, and AVR/CABG. Female sex and increased age were associated with increased odds of mortality in TAVR, CABG, and AVR/CABG. Private insurance was associated with a decreased odds of mortality in patients undergoing AVR., Conclusions: These findings reveal significant disparities in patient outcomes after routine cardiac operations that are associated with socioeconomic status. Patients who did not have private insurance or had lower incomes were found to be at risk for increased LOS. Women were at a higher risk of mortality for several operations, a finding which has been previously described elsewhere. Private insurance conveyed a decreased odds of mortality in patients undergoing AVR. This data set serves to highlight differences in healthcare outcomes based on a variety of socioeconomic, geographic, and other inherent factors. Additional research is needed to identify the mechanisms behind these disparities with the goal of providing equitable care to all patients., (© 2022 Wiley Periodicals LLC.)

- Abstract
Introduction: Patient engagement, adaptation and self-management play a critical role in improving Health Related Quality of Life (HRQOL) and reducing health care utilization in chronic disorders. There is no data on the level of patient engagement in patients with cyclic vomiting syndrome (CVS); we thus sought to determine their level of engagement and its association with clinical covariates., Methods: The Patient Activation Measure (PAM-13), a validated tool that measures the degree of patient engagement in their health was administered prospectively to patients with CVS. Data on demographics, health care utilization, and HRQOL (using the NIH PROMIS 10) were obtained. Patients were stratified into low engagement (PAM 1 & 2) and high engagement (PAM 3 & 4). The Fisher's exact test and Wilcoxon rank-sum tests were used to identifying significant differences between the groups., Results: Of 96 patients, 45% of patients had low levels of patient engagement. On multivariate analysis, low patient engagement was significantly associated with an increased number of CVS hospitalizations in the past year (aOR 1.26 [1.07, 1.54] p = .010), lower mental HRQOL scores (aOR 0.88 [0.78, 0.97] p = .022), current tobacco use (aOR 4.85 [1.24, 22.74] p = .031), and patients who were newly established in a specialized CVS clinic (aOR 44.40 [5.38, 70.02] p = .002)., Conclusion: Almost half of CVS patients demonstrate poor patient engagement, which is associated with poor outcomes. Identifying these patients and treatment in a specialized CVS center can potentially improve HRQOL, reduce health care utilization and improve overall healthcare outcomes.

- Abstract
The classic Philadelphia chromosome-negative myeloproliferative neoplasms (MPN) consist of myelofibrosis, polycythemia vera, and essential thrombocythemia and are a heterogeneous group of clonal blood disorders characterized by an overproduction of blood cells. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for MPN were developed as a result of meetings convened by a multidisciplinary panel with expertise in MPN, with the goal of providing recommendations for the management of MPN in adults. The Guidelines include recommendations for the diagnostic workup, risk stratification, treatment, and supportive care strategies for the management of myelofibrosis, polycythemia vera, and essential thrombocythemia. Assessment of symptoms at baseline and monitoring of symptom status during the course of treatment is recommended for all patients. This article focuses on the recommendations as outlined in the NCCN Guidelines for the diagnosis of MPN and the risk stratification, management, and supportive care relevant to MF.

- Abstract
Background: Temporary mechanical circulatory support (tMCS) devices are used for patients with severe cardiac or respiratory failure; however, these patients are at high risk for clotting and bleeding. The best method to monitor heparin in these patients has not been established., Objective: To determine the risks for bleeding and clotting while monitoring heparin with either anti-Xa or activated clotting time (ACT) in tMCS patients., Methods: A retrospective cohort study was conducted on tMCS patients who received heparin adjusted according to an anti-Xa or ACT protocol. The primary outcome was incidence of major bleeding. Pertinent secondary outcomes were individual components of the primary outcome, clotting events, and time to therapeutic range., Results: There were 103 patients included in the study: 53 in the ACT group and 50 in the anti-Xa group. Overall, there were 30 (56.6%) patients with major bleeding in the ACT group, compared with 16 (32%) patients in the anti-Xa group ( P = 0.017). An anti-Xa-based protocol was associated with a decreased hazard of major bleeding (hazard ratio = 0.388 [0.215-0.701]; P = 0.002) in the univariate analysis. In the multivariable analysis, an anti-Xa protocol remained associated with a significantly lower hazard of bleeding. Findings were similar when broken down into more discrete subgroups of the entire cohort, extracorporeal membrane oxygenation life support (ECMO), and non-ECMO groups., Conclusion and Relevance: Anti-Xa monitoring was associated with a lower hazard of bleeding during tMCS compared to an ACT-based protocol. Further studies should evaluate if anti-Xa monitoring should be preferentially used in tMCS.

- Abstract
Objective: In patients with primary aldosteronism, adrenal venous sampling (AVS) is performed to determine the presence of unilateral or bilateral adrenal disease. During AVS, verification of catheter positioning within the left adrenal vein (AV) and the right AV by comparison of AV and inferior vena cava (IVC) cortisol levels can be variable. The objective of this study was to determine the utility of AV epinephrine levels in assessing successful AV cannulation., Methods: This was a single institution, retrospective review of patients who underwent AVS with cosyntropin stimulation for primary aldosteronism between 2009 and 2018. Successful cannulation of the AV was defined by an AV/IVC cortisol ratio selectivity index (SI) ≥3:1. Epinephrine thresholds to predict catheter placement in the AV were determined using logistic regression. The calculated epinephrine thresholds were compared with previously published thresholds., Results: AVS was performed on 101 consecutive patients and, based on the SI, successful cannulation of the left AV and right AV occurred in 98 (97%) and 91(90%) patients, respectively. The calculated optimal epinephrine threshold to predict AV cannulation was 364 pg/mL (sensitivity, 92.1%; specificity, 94.6%) and the calculated optimal AV/IVC epinephrine ratio threshold was 27.4, (sensitivity, 92.1%; specificity, 91.3%). Among the 14 patients with failed AV cannulation, 3 patients would have been considered to have successful AVS using AV epinephrine levels >364 pg/mL and AV/IVC epinephrine ratio >27.4 thresholds., Conclusion: Obtaining 2 right AV samples routinely as well as AV and IVC epinephrine levels during AVS could prevent unnecessary repeat AVS in patients with failed AV cannulation based on cortisol-based SI <3:1., (Published by Elsevier Inc.)

- Abstract
Purpose: Investigate the relationship between dosimetric parameters with local control (LC) and complications following transperineal high-dose rate (HDR) interstitial brachytherapy (ISBT) for gynecologic (GYN) malignancies., Methods and Materials: Between 2001 and 2016, 59 patients were treated for primary or recurrent GYN malignancies. Most patients received external beam irradiation, followed by transperineal ISBT via the Syed-Neblett applicator set with CT-based planning. Treatment plans were retrospectively reviewed to evaluate for an association among LC or toxicity with the equivalent dose at 2 Gy per fraction (EQD2) for the clinical target volume (CTV), 0.1 cc (D0.1cc), and 2 cc (D2cc) volumes of the organs at risk (OAR), low/high dose volumes for the OAR and CTV, and ratio of dose at the core vs. the implant periphery., Results: The median follow-up among survivors was 24 months. 34% of patients had a component of local failure and in 12%, this was isolated. Late grade 3 (G3) toxicity occurred in 15% of patients. There were no G4-5 toxicities. Rectal D0.1cc > 75 Gy trended toward significance in predicting the development of non-fistula late G2-3 rectal complications. Bladder D0.1cc > 94 Gy significantly predicted for the development of late G2-3 vesicovaginal fistula formation. The ratio of the total dose at the vaginal surface to the needle periphery above 121% trended in predicting for any complication or fistula formation., Conclusions: HDR ISBT combined with EBRT achieved LC in 66% of patients with advanced or recurrent GYN cancers. Rectal and bladder D0.1cc doses may be predictive of complications as may the ratio of the implant dose at the core vs. periphery., (Copyright © 2021 American Brachytherapy Society.

- Abstract
Introduction and Objectives: A pediatric group with 25 clinics and 150 providers used multifaceted approaches to implement workflow processes and an electronic health record (EHR) flowsheet to improve child developmental screening. The key outcome was developmental screening done for every patient during 3 periods between ages 8 and 36 months. Identification of developmental concerns was the secondary study outcome. Screening rates and referrals were hypothesized to be optimized for children regardless of demographic backgrounds., Methods: During preventive visits, developmental screens targeted patients in age groups 8 to 12, 13 to 24, and 25 to 36 months. EHRs were analyzed for screening documentation, results, and referrals by patient demographics. Fifteen pediatric professionals were interviewed about their qualitative experiences. Quality improvement interventions included appointing clinic champions, training staff about the screening process and responsibilities, using a standardized tool, employing plan-do-study-act cycles, posting EHR prompts, providing financial incentives, and monitoring screening rates using control charts., Results: Within 25 months, screening rates improved from 60% to >95% within the 3 preventive visit age groups for a total of more than 30 000 children. Professionals valued the team process improvements. Children enrolled in Medicaid, black children, and those living in lower income zip codes had lower screening rates than privately insured, white children, and those living in higher income areas. Ages and Stages Questionnaire 3rd edition results were significantly different by gender, race/ethnicity, insurance, and income categories across all groups. Referral rates varied by race/ethnicity and zip code of residence., Conclusions: This project resulted in an effective and efficient process to improve child developmental screening that was valued by pediatric professionals. Analyses of patient demographics revealed disparities in services for the most vulnerable families. Ongoing quality improvement, health services research, and advocacy offer hope to improve health equity.

- Abstract
Introduction: Prior data suggest associations between hearing loss, cardiovascular (CV) risk factors, and CV disease. Whether specific hearing loss patterns, including a strial pattern associated with inner ear vascular disease, are associated with systemic endothelial dysfunction and carotid intima-media thickness (IMT) remains unclear., Methods: We evaluated participants without prevalent CVD in the Framingham Offspring Study who underwent formal audiogram testing and brachial and carotid artery ultrasounds. Audiograms were categorized as normal or as belonging to one of four abnormal patterns: cochlear-conductive, low-sloping, sensorineural, or strial. Endothelial function as measured by brachial artery flow-mediated dilation (FMDmm and FMD%). Internal and common intima-media thicknesses (icIMT and ccIMT, respectively) were compared between audiogram patterns., Results: We studied 1672 participants (mean age 59 years, 57.6% women). The prevalence of each hearing pattern was as follows: 43.7% normal; 20.3% cochlear-conductive; 20.3% sensorineural; 7.7% low-sloping; and 8.0% strial. Strial pattern hearing loss was nearly twice as prevalent ( p = 0.001) in those in the highest quartile of ccIMT and nearly 50% higher in those in the highest icIMT quartile ( p = 0.04). There were no statistically significant differences between the prevalence of the strial pattern comparing the lowest quartiles of FMDmm and FMD% with the upper three quartiles. Age- and sex-adjusted linear regression models did not show significant associations between the vascular measures and hearing patterns., Conclusion: Abnormal hearing patterns were not significantly associated with impaired brachial FMD and increased carotid IMT after adjusting for age and sex effects, which may reflect age and sex-related distributional differences based on hearing loss pattern.
