Aim: Determine the influence of SLCO1B3 polymorphisms on outcomes in kidney transplant recipients. Materials & methods: We retrospectively evaluated 181 adult kidney transplant recipients receiving mycophenolate. Outcomes included treated biopsy-proven acute rejection (tBPAR), de novo donor-specific antibody (dnDSA) formation, graft survival, patient survival and mycophenolate-related adverse effects among SLCO1B3 genotypes. Results: The presence of SLCO1B3 variants was not associated with increased risk of tBPAR (HR: 1.45, 95% CI: 0.76–2.74), dnDSA (HR: 0.46, 95% CI: 0.16–1.36) or composite of tBPAR or dnDSA (HR: 1.14, 95% CI: 0.64–2.03). Graft and patient survival were reduced among variant carriers; however, inconsistent findings with the primary analysis suggest these associations were not due to genotype. Adverse effects were similar between groups. Conclusion: Presence of SLCO1B3 polymorphisms were not predictive of rejection or dnDSA in kidney transplant recipients.

Malignant tumours arising from the sublingual glands are very rare, and the extent and frequency of local invasion or regional spread in malignant sublingual gland tumour (MSLT) has not been fully studied due to the disease rarity. To provide comprehensive features of local and regional spread of MSLT, we reviewed 20 surgical cases for detailed pathological analyses among 26 cases diagnosed as having primary MSLT. Adenoid cystic carcinoma (ACC) was the most common pathological subtype, followed by mucoepidermoid carcinoma. Disease-free and overall survivals at 5 years were 76.1 % and 77.7 %, respectively. High-grade malignant tumours and grade 2-3 ACC accounted for 41.7 % and 85.7 %. Clinical and pathological extraparenchymal extensions were found in 34.6 % and 80.0 %, respectively. Tumour invasion to the lingual nerve and submandibular gland/ductal system were also detected in 40.0 % and 28.6 %. The incidences of lingual nerve invasion in ACC and ACC ≥4 cm were 30.8 % and 42.9 %. Regional nodal involvement occurred in seven of 26 cases, and all metastatic lymph nodes were found in neck levels Ib and IIa. In summary, a significant portion of MSLT cases consisted of high-grade tumours and grade 2-3 ACC; therefore local invasion into adjacent structures should be cautiously evaluated in cases of MSLT.

Purpose To investigate the underlying reason for the previously observed impact of baseline lesion size, number, and circularity on geographic atrophy (GA) growth rate. Design Retrospective analysis of a multicenter, prospective, randomized controlled trial. Participants Age-Related Eye Disease Study participants with GA secondary to nonexudative age-related macular degeneration. Methods We manually delineated atrophic lesions on color fundus photographs of 318 eyes with GA followed up over at least 2 visits (mean follow-up duration, 5.1 ± 3.0 years). We calculated GA area growth rate for each eye based on the first and last visit. GA perimeter-adjusted growth rate was defined as the ratio between GA area growth rate and mean GA perimeter between the first and last visit for each eye. Main Outcome Measures GA area growth rate, growth rate of the square root of GA area, and GA perimeter-adjusted growth rate. Results GA area growth rate was correlated strongly with mean GA perimeter (r2 = 0.66). GA area growth rate was associated with baseline GA area (r2 = 0.39; P Conclusions The growth rate of GA area is associated strongly with lesion perimeter. This relationship explains the previously observed influences of baseline GA size, lesion number, and circularity on GA growth rate. GA perimeter-adjusted growth rate is uncorrelated with the 3 morphologic factors and may serve as a surrogate outcome measure to monitor GA progression in future studies.

Background The field of consultation-liaison psychiatry has generated a relatively small number of rigorous clinical trials that guide clinical care. Consequently, there is a need for a consensus-building process to inform best practices for common clinical dilemmas in consultation-liaison psychiatry. Objective We review several consensus-building approaches in academic medicine and describe a novel educational process called a “conseminar,” which is intended to minimize the variability in teaching and practice on a service staffed by multiple faculty members. Methods The conseminar is an iterative group exercise among faculty who attend on a consultation-liaison service. Faculty members generate a list of candidate topics and then prioritize those topics for a focused and critical literature review, aided by a librarian. In the absence of definitive clinical trial data or established practice guidelines, the faculty articulates a consensus “best-practice” approach and creates a brief document that summarizes specific recommendations for learners on the service. Conclusions The conseminar process can minimize variability among consultation-liaison faculty within a single institution with respect to the diagnostic and treatment recommendations conveyed to trainees. Furthermore, conseminar documents can be shared across institutions to promote more consistent teaching and practice within consultation-liaison psychiatry.

STUDY OBJECTIVE This study investigated the effect of CYP3A5 phenotype on time in therapeutic range (TTR) of tacrolimus post-transplant in pediatric patients. DESIGN AND DATA SOURCE This retrospective study assessed medical records of pediatric kidney and heart recipients with available CYP3A5 genotype for tacrolimus dosing, troughs, and the clinical events (biopsy-proven acute rejection [BPAR] and de novo donor-specific antibodies [dnDSA]). MEASUREMENTS AND MAIN RESULTS The primary outcome, mean TTR in the first 90 days post-transplant, was 9.0% (95% CI: -16.1, -1.9) lower in CYP3A5 expressers (p = 0.014) when adjusting for time to therapeutic concentration and organ type. There was no difference between CYP3A5 phenotypes in time to the first clinical event using TTR during the first 90 days. When applying TTR over the first year, there was a significant difference in event-free survival (EFS) which was 50.0% for CYP3A5 expressers/TTR

Aims There is a wide spectrum of diseases associated with pulmonary hypertension, pulmonary vascular remodelling, and right ventricular dysfunction. The NIH-sponsored PVDOMICS network seeks to perform comprehensive clinical phenotyping and endophenotyping across these disorders to further evaluate and define pulmonary vascular disease. Methods and results Echocardiography represents the primary non-invasive method to phenotype cardiac anatomy, function, and haemodynamics in these complex patients. However, comprehensive right heart evaluation requires the use of multiple echocardiographic parameters and optimized techniques to ensure optimal image acquisition. The PVDOMICS echo protocol outlines the best practice approach to echo phenotypic assessment of the right heart/pulmonary artery unit. Conclusion Novel workflow processes, methods for quality control, data for feasibility of measurements, and reproducibility of right heart parameters derived from this study provide a benchmark frame of reference. Lessons learned from this protocol will serve as a best practice guide for echocardiographic image acquisition and analysis across the spectrum of right heart/pulmonary vascular disease.

A novel coronavirus has had global impact on individual health and health care delivery. In this C4 article, contributors discuss various aspects of transplantation including donor and recipient screening, management of infected patients, and prevention of coronavirus disease (COVID). Donor screening with SARS-CoV-2 nucleic acid testing (NAT) close to the time of procurement is recommended. Many programs are also screening all potential recipients at the time of admission. The management of COVID has evolved with remdesivir emerging as a new potential option for transplant recipients. Dexamethasone has also shown promise and convalescent plasma is under study. Prevention strategies for transplant candidates and recipients are paramount. Pediatric-specific issues are also discussed. Strategies for the psychological well-being of patients and providers are also imperative, in addition to future research priorities for transplantation.

To examine the association between geographic atrophy (GA) disease characteristics and mortality risk. We manually delineated color fundus photographs of 209 Age-Related Eye Disease Study (AREDS) participants with GA secondary to age-related macular degeneration to identify total area of atrophy, GA effective radius growth rate, disease laterality, and the presence of foveal center involvement. Associations between GA characteristics and mortality were assessed with Cox proportional hazards models adjusted for health status indicators. During a median follow-up of 6.8 years, 48 (23.0%) participants with GA died. In adjusted models, accounting for age, sex, and health status, participants with total GA area in the highest quartile had a significantly increased risk of all-cause mortality compared to those with total GA area in the lowest quartile (hazard ratio [HR], 3.42; 95% confidence interval [CI], 1.32–8.86; P = 0.011). GA effective radius growth rate, bilateral disease, and the presence of foveal center involvement were not significantly associated with mortality. In a multivariable model, including health status indicators and all GA characteristics, total area of atrophy in the highest quartile remained significantly associated with mortality (HR, 4.65; 95% CI, 1.29–16.70; P = 0.019). More extensive GA, as indicated by a greater total area of atrophy, was associated with an increased risk of all-cause mortality in our cohort. The extent of GA may reflect the extent of underlying disease processes that contribute to greater mortality risk, further suggesting that GA may be part of a systemic rather than purely ocular disease process.

Increased modifications to tacrolimus therapy may indicate a higher burden on healthcare resources. The purpose of this study was to evaluate whether CYP3A5 genotype was predictive of healthcare resource utilization in pediatric renal and heart transplant recipients.Patients and Methods: Patients < 18 years of age with a renal or heart transplant between 6/1/2014– 12/31/2018 and tacrolimus-based immunosuppression were included. Secondary use samples were obtained for CYP3A5 genotyping. Clinical data was retrospectively collected from the electronic medical record. Healthcare resource utilization measures included the number of dose changes, number of tacrolimus concentrations, length of stay, number of clinical encounters, and total charges within the first year post-transplant. Rejection and donor-specific antibody (DSA) formation within the first year were also collected. The impact of CYP3A5 genotype was evaluated via univariate analysis for the first year and multivariable analysis at 30, 90, 180, 270, and 365 days post-transplant.Results: Eighty-five subjects were included, 48 renal transplant recipients and 37 heart transplant recipients. CYP3A5 genotype was not associated with any outcomes in renal transplant, however, a CYP3A5 expresser phenotype was a predictor of more dose changes, more tacrolimus concentrations, longer length of stay, and higher total charges in heart transplant recipients. CYP3A5 genotype was not associated with rejection or DSA formation. Age and induction therapy were associated with higher total charges.Conclusion: CYP3A5 genotype may predict healthcare resource utilization in the first year post-transplant, although this may be mitigated by differences in tacrolimus management. Future studies should evaluate the impact of genotype-guided dosing strategies for tacrolimus on healthcare utilization resources.Keywords: pharmacogenetics, cost of care, pediatric transplant

Chyluria is characterized by chyle in the urinary tract and often presents as milky-white urine. We present a case of chyluria from a lymphatic malformation in a 13-year-old boy diagnosed using dynamic intranodal contrast-enhanced magnetic resonance (MR) lymphangiography. This report demonstrates the utility of intranodal lymphangiography and interstitial lymphatic embolization to treat a pediatric patient presenting with persistent chyluria. Glue migration into the urinary collecting system is a potential complication of this procedure that can be mitigated by adjusting the n-butyl cyanoacrylate dilution with Lipiodol.

The use of direct-acting oral anticoagulants (DOACs) has increased secondary to the mounting evidence for comparable efficacy and potentially superior safety to vitamin K antagonists (VKAs) in the general population. However, insufficient data regarding DOAC use in solid organ transplant (SOT) recipients and numerous pharmacokinetic and pharmacodynamic considerations limit their use in this highly selected patient population. A systematic review of recent clinical evidence on the safety and efficacy of DOACs compared to VKAs in SOT recipients was conducted. Additional considerations including transplant-specific strategies for DOAC reversal and common pharmacokinetic/pharmacodynamic concerns were also reviewed. Although current evidence is limited to single-center retrospective analyses, DOACs, especially apixaban, appear to be a safe and effective alternative to VKAs for SOT recipients with stable graft function and without drug-drug interactions. Reliable data on DOAC reversal at the time of transplant surgery are lacking, and clinicians should consider idarucizumab, andexanet alfa, and other non-specific reversal agents on an individual patient basis. There is no evidence supporting deviations from the Food and Drug Administration labeling recommendations for DOAC dosing in the setting of drug-drug interactions, obesity, and renal function, especially in patients on hemodialysis.

BackgroundThe macular central 1 mm diameter zone is crucial to patients’ visual acuity, but the long-term natural history of central sparing in eyes with geographic atrophy (GA) is unknown.MethodsWe manually segmented GA in 210 eyes with GA involving central 1 mm diameter zone (mean follow-up=3.8 years) in the Age-Related Eye Disease Study. We measured the residual area in central 1 mm diameter zone and calculated central residual effective radius (CRER) as square root of (residual area/π). A linear mixed-effects model was used to model residual size over time. We added a horizontal translation factor to each data set to account for different durations of GA involving the central zone.ResultsThe decline rate of central residual area was associated with baseline residual area (p=0.008), but a transformation from central residual area to CRER eliminated this relationship (p=0.51). After the introduction of horizontal translation factors to each data set, CRER declined linearly over approximately 13 years (r2=0.80). The growth rate of total GA effective radius was 0.14 mm/year (95% CI 0.12 to 0.15), 3.7-fold higher than the decline rate of CRER (0.038 mm/year, 95% CI 0.034 to 0.042). The decline rate of CRER was 53.3% higher in eyes with than without advanced age-related macular degeneration in the fellow eyes at any visit (p=0.007).ConclusionsCRER in eyes with GA declined linearly over approximately 13 years and may serve as an anatomic endpoint in future clinical trials aiming to preserve the central zone.

Background Guidelines regarding head and neck surgical care have evolved during the coronavirus-19 (COVID-19) pandemic. Data on operative management have been limited. Methods We compared two cohorts of patients undergoing head and neck or reconstructive surgery between March 16, 2019 and April 16, 2019 (pre-COVID-19) and March 16, 2020 and April 16, 2020 (COVID-19) at an academic center. Perioperative, intraoperative, and postoperative outcomes were recorded. Results There were 63 operations during COVID-19 and 84 operations during pre-COVID-19. During COVID-19, a smaller proportion of patients had benign pathology (12% vs 20%, respectively) and underwent thyroid procedures (2% vs 23%) while a greater proportion of patients underwent microvascular reconstruction±ablation (24% vs 12%,). Operative times increased, especially among patients undergoing microvascular reconstruction±ablation (687 ± 112 vs 596 ± 91 minutes, P = .04). Complication rates and length of stay were similar. Conclusions During COVID-19, perioperative outcomes were similar, operative time increased, and there were no recorded transmissions to staff or patients. Continued surgical management of head and neck cancer patients can be provided safely.

Atherosclerotic plaque detection by carotid ultrasound provides cardiovascular disease risk stratification. The advantages and disadvantages of two-dimensional (2D) and three-dimensional (3D) ultrasound methods for carotid arterial plaque quantification are reviewed. Advanced and emerging methods of carotid arterial plaque activity and composition analysis by ultrasound are considered. Recommendations for the standardization of focused 2D and 3D carotid arterial plaque ultrasound image acquisition and measurement for the purpose of cardiovascular disease stratification are formulated. Potential clinical application towards cardiovascular risk stratification of recommended focused carotid arterial plaque quantification approaches are summarized.

Purpose To describe the demographics, clinical presentation, treatment, and outcomes of a rare cohort with simultaneous orbital and intracranial abscesses. Methods A historical cohort study of 17 patients with simultaneous orbital and intracranial abscesses between 2010 and 2018 was performed. The demographics, location of abscesses, treatment, and outcomes of these patients were analyzed. Results The mean age was 26.9 years (range 5-83 years). Fourteen patients (82%) were male. In this cohort, the most common orbital abscess location was the superior orbit, involved in 14 patients (82%). The most common site of intracranial abscess was the frontal lobe, involved in 16 patients (94%). Concurrent sinus disease was present in 16 patients (94%). Surgical evacuation was the standard of treatment, with 94% of patients undergoing at least one surgical procedure. Streptococcus species were the most common, isolated from 6 sinus cultures (43%), 3 orbitotomy cultures (21%), and 4 craniectomy cultures (36%). Staphylococcus species were also common. Most patients (94%) had stable or improved mental status and visual function at the conclusion of their treatment. Conclusions Simultaneous orbital and intracranial abscesses are rare. Local invasion from the orbit into the intracranial space may occur from direct spread, thus superior orbital abscesses pose the greatest risk for intracranial spread. Additional factors such as infection with Streptococcus and Staphylococcus species as well as male sex appear to be risk factors for intracranial spread. For those who develop intracranial abscesses, young age and absence of seizures or altered mental status at presentation may be associated with favorable outcomes.

Background Hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg) negative and hepatitis B core antibody (anti-HBc) positive kidney transplant recipients ranges between 1.4-9.6%. Limited evidence is available regarding routine antiviral prophylaxis and identifiable risk factors for HBV reactivation in this population. Methods In this multi-center retrospective study, we evaluated the prevalence of HBV reactivation in HBsAg-negative anti-HBc-positive kidney transplant recipients who did or did not receive antiviral prophylaxis. The primary outcome assessed the prevalence of HBV reactivation, defined as a positive HBV DNA by PCR of any viral load at or above the minimal detection level. The principal safety outcomes assessed 1-year graft survival, 1-year all-cause mortality, biopsy proven acute rejection (BPAR), and antibody mediated rejection (AMR). Results One-hundred sixty-one patients met inclusion criteria and comprised of two groups, antiviral prophylaxis (n=14) and no antiviral prophylaxis (n=147). Of patients who did not receive prophylaxis only five (3.4%) experienced HBV reactivation whereas one (7.1%) patient in the prophylaxis group experienced reactivation over a median follow-up of 1103 days (p= 0.43). Furthermore, there were no differences with respect to all secondary outcomes. Statistical analysis demonstrated delayed graft function to be a significant factor associated with HBV reactivation. Conclusion These study results suggest that the prevalence of HBV reactivation in HBsAg-negative anti-HBc-positive kidney transplant recipients is low, regardless of antiviral prophylaxis. Furthermore, there were no significant graft related outcomes among those that did experience reactivation. This article is protected by copyright. All rights reserved.

Alterations in metabolism and bioenergetics are hypothesized in the mechanisms leading to pulmonary vascular remodeling and heart failure in pulmonary hypertension (PH). To test this, we performed metabolomic analyses on 30 PH individuals and 12 controls. Furthermore, using 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography, we dichotomized PH patients into metabolic phenotypes of high and low right ventricle (RV) glucose uptake and followed them longitudinally. In support of metabolic alterations in PH and its progression, the high RV glucose group had higher RV systolic pressure (p

Quantitative sensory testing (QST) is used to evaluate the function of the somatosensory system in dogs by assessing the response to applied mechanical and thermal stimuli. QST is used to determine normal dogs' sensory thresholds and evaluate alterations in peripheral and central sensory pathways caused by various disease states, including osteoarthritis, spinal cord injury, and cranial cruciate ligament rupture. Mechanical sensory thresholds are measured by electronic von Frey anesthesiometers and pressure algometers. They are determined as the force at which the dog exhibits a response indicating conscious stimulus perception. Hot thermal sensory thresholds are the latency to respond to a fixed or ramped temperature stimulus applied by a contact thermode. Following a consistent protocol for performing QST and paying attention to details of the testing environment, procedure, and individual study subjects are critical for obtaining accurate QST results for dogs. Protocols for the standardized collection of QST data in dogs have not been described in detail. QST should be performed in a quiet, distraction-free environment that is comfortable for the dog, the QST operator, and the handler. Ensuring that the dog is calm, relaxed, and properly positioned for each measurement helps produce reliable, consistent responses to the stimuli and makes the testing process more manageable. The QST operator and handler should be familiar and comfortable with handling dogs and interpreting dogs' behavioral responses to potentially painful stimuli to determine the endpoint of testing, reduce stress, and maintain safety during the testing process.

PURPOSE: To assess the influence of lesion morphology and location on geographic atrophy (GA) growth rate. METHODS: We manually delineated GA on color fundus photographs of 237 eyes in the Age-Related Eye Disease Study. We calculated local border expansion rate (BER) as the linear distance that a point on the GA border traveled over 1 year based on a Euclidean distance map. Eye-specific BER was defined as the mean local BER of all points on the GA border in an eye. The percentage area affected by GA was defined as the GA area divided by the total retinal area in the region. RESULTS: GA enlarged 1.51 ± 1.96 mm2 in area and 0.13 ± 0.11 mm in distance over 1 year. The GA area growth rate (mm2/y) was associated with the baseline GA area (P < 0.001), perimeter (P < 0.001), lesion number (P < 0.001), and circularity index (P < 0.001); in contrast, eye-specific BER (mm/y) was not significantly associated with any of these factors. As the retinal eccentricity increased from 0 to 3.5 mm, the local BER increased from 0.10 to 0.24 mm/y (P < 0.001); in contrast, the percentage of area affected by GA decreased from 49.3% to 2.3%. CONCLUSIONS: Using distance-based measurements allows GA progression evaluation without significant confounding effects from baseline GA morphology. Local GA progression rates increased as a function of retinal eccentricity within the macula which is opposite of the trend for GA distribution, suggesting that GA initiation and enlargement may be mediated by different biological processes.

Background Heart disease is the leading non-obstetric cause of maternal death during pregnancy. In this field, the emergence of pandemic COVID-19 has caused the worst-case scenario considering that pregnant women are more susceptible to viral infections, and preexisting cardiac disease is the most prevalent co-morbidity among COVID-19 deaths. Purpose To assess the maternal and fetal outcomes of COVID-19 during pregnancy of women with heart diseases. Methods During the year 2020, among 82 pregnant women with heart disease followed consecutively at the Instituto do Coração-InCor, seven of them with an average age of 33.2 years had COVID-19 during their pregnancies. The underlying heart diseases were rheumatic valve disease (5 pt), congenital heart disease (1 pt) and one case with acute myocarditis, without preexisting cardiopathy. The prescription (antibiotics, inotropes, corticosteroids and others) used was according to the clinical conditions required for each patient, however subcutaneous or intravenous heparin was used in all patients. Results Only one case had an uneventful maternal-fetal course, the other six women required hospitalization / ICU for an average of 25.3 days, including the need for mechanical ventilation in two of them. Serious complications were related to respiratory failure (ADRS), recurrent atrial flutter with hemodynamic instability, acute pulmonary edema, and cardiogenic shock associated with sepsis which caused two maternal deaths. There were two emergency mitral valve interventional, percutaneous balloon valvuloplasty and valve bioprosthesis replacement, respectively. There were five premature births with an average gestational age of 34.2 weeks of gestation, which resulted in one stillbirth. Pathological findings of three placental and the six-months follow-up of the babies did not confirm vertical transmission of COVID-19. Conclusions The uncertain evolution given of the overlapping complications of three conditions – COVID-19, pregnancy, and heart disease – implies an increased risk for women with heart diseases of childbearing age, for whom pregnancy should be discouraged and planned after vaccination Funding Acknowledgement Type of funding sources: None.

Background Recently, 4S-AF scheme consisting of four essential domains requiring for integrated management of atrial fibrillation (AF), including stroke prevention, symptom severity, severity of AF burden, and substrate for AF, has been proposed for the structured characterization of AF. Purpose To classify patients with AF applying 4S-AF scheme, evaluate how rhythm control and stroke prevention strategies were applied according to the 4S-AF scheme, and analyze the association between 4S-AF scheme score and the risk of clinical outcome, composite of stroke and admission for heart failure in patients with AF. Methods Using the data from the COmparison study of Drugs for symptom control and complication prEvention of Atrial Fibrillation (CODE-AF) registry from June 2015 to October 2020, we identified patients with AF who had information about 4S. The 4S-AF scheme score was calculated by stroke risk (truly low risk patients = 0; otherwise = 1), symptom severity (no symptom = 1; presence of symptom = 1), severity of AF burden (paroxysmal = 0, persistent = 1, and long-persistent to permanent = 2), substrate for AF (add 1 if >75 years; no comorbidity=1, 1 comorbidity = 1, 2 or more comorbidities = 2; left atrial anteroposterior diameter Results Among 8199 patients with AF, the 4S-AF scheme scores of 0, 1, 2, 3, 4, 5, and ≥6 were 2.5%, 5.6%, 9%, 17.1%, 20.1%, 17.6%, and 28%, respectively. Patients with higher scores were tended to be older, had higher CHA2DS2-VASc score, included less proportion of paroxysmal AF, and showed larger left atrial size (Table). According to 4S-AF scheme, physicians preferred to apply a rhythm control strategy through both performing catheter ablation and prescribing antiarrhythmic agents in patients with lower 4S-AF scheme score (Figure). Oral anticoagulation rates were higher in patients with higher 4S-AF scheme score owing to higher CHA2DS2-VASc scores of these patients (Figure). The incidence rates of composite clinical outcomes were increased with increasing in 4S-AF scheme score (Figure). When grouping 4S-AF scheme score 0 and 1 as group A, 2 to 4 as group B, 5 as group C, and 6 as group D, group B, C, and D were associated with a higher risk of the composite clinical outcomes by 3.4, 7.9 and 11.5-fold compared to group A, respectively (Figure). Conclusions The 4S-AF scheme score was well-associated with the risk of stroke and admission for heart failure in patients with AF. Although the 4S-AF scheme might be already reflected in clinical practice when physicians determined the rhythm control and stroke prevention strategies for their AF patients, more systematic approach should be utilized for better clinical outcomes in patients with AF.

PURPOSE The purpose of this study was to compare the safety and efficacy of two valganciclovir (VGCV) institutional dosing protocols for cytomegalovirus (CMV) prophylaxis in liver transplant (LT) recipients with CMV serotype donor +/recipient- (D+/R-). METHODS This was a single-center review of CMV D+/R- adult LT recipients who received VGCV 450 mg/day for 90 days (low-dose) or VGCV 900 mg/day for 180 days (standard-dose). The primary outcome was incidence of CMV disease at 1 year. Secondary outcomes included rates of CMV syndrome, end-organ disease, breakthrough infection, and resistance. Neutropenia, early discontinuation of VGCV, growth colony stimulating factors use (G-CSF), biopsy-proven rejection (BPAR), graft loss, and death at 1 year were analyzed. RESULTS Ninety-six CMV D+/R- LT recipients were included. Although no difference in CMV disease was observed (low-dose 26% vs. standard-dose 23%, p = 0.71), 75% of CMV infections in the low-dose group presented with end-organ disease. Ganciclovir (GCV) resistance was observed only in the low-dose group (n = 2). Significantly more patients in the standard-dose group developed neutropenia (low-dose 10% vs 60% standard-dose, p

Background: Metalworking fluids (MWFs) are mixtures with inhalation exposures as mists, dusts, and vapors, and dermal exposure in the dispersed and bulk liquid phase. A quantitative risk assessment was performed for exposure to MWF and respiratory disease. Methods: Risks associated with MWF were derived from published studies and NIOSH Health Hazard Evaluations, and lifetime risks were calculated. The outcomes analyzed included adult onset asthma, hypersensitivity pneumonitis, pulmonary function impairment, and reported symptoms. Incidence rates were compiled or estimated, and annual proportional loss of respiratory capacity was derived from cross-sectional assessments. Results: A strong healthy worker survivor effect was present. New-onset asthma and hypersensitivity pneumonitis, at 0.1 mg/m3 MWF under continuous outbreak conditions, had a lifetime risk of 45%; if the associated microbiological conditions occur with only 5% prevalence, then the lifetime risk would be about 3%. At 0.1 mg/m3, the estimate of excess lifetime risk of attributable pulmonary impairment was 0.25%, which may have been underestimated by a factor of 5 or more by a strong healthy worker survivor effect. The symptom prevalence associated with respiratory impairment at 0.1 mg/m3 MWF was estimated to be 5% (published studies) and 21% (Health Hazard Evaluations). Conclusion: Significant risks of impairment and chronic disease occurred at 0.1 mg/m3 for MWFs in use mostly before 2000. Evolving MWFs contain new ingredients with uncharacterized long-term hazards.

BACKGROUND AND PURPOSE The rate at which the chance of a good outcome of endovascular stroke therapy (EVT) decays with time when eligible patients are selected by baseline diffusion-weighted magnetic resonance imaging (DWI-MRI) and whether ischaemic core size affects this rate remain to be investigated. METHODS This study analyses a prospective multicentre registry of stroke patients treated with EVT based on pretreatment DWI-MRI that was categorized into three groups: small [Diffusion-Weighted Imaging Alberta Stroke Program Early Computed Tomography Score (DWI-ASPECTS)] (8-10), moderate (5-7) and large (

OBJECTIVE: To evaluate the appropriateness of proton-pump inhibitor (PPI) prescribing and reduce the number of outpatients on long-term PPI therapy, defined as greater than or equal to one year. DESIGN: Phase I was retrospective and evaluated the appropriateness of PPI prescribing. Phase II was prospective and involved implementation of a pharmacist-driven PPI step-down protocol. SETTING: This study was conducted in an outpatient setting at Veterans Affairs Hudson Valley Health Care System. PATIENTS, PARTICIPANTS: Patients were limited to a single primary care provider and were required to fill an outpatient PPI prescription between August 15, 2015, and August 15, 2016. INTERVENTIONS: After patients were identified in Phase I as having an inappropriate indication for long-term PPI therapy, they were contacted by a pharmacist to complete the step-down protocol. The patients then received a call two weeks after completing each step. MAIN OUTCOME MEASURE(S): To determine the number of patients without an indication for long-term PPI therapy that could successfully complete the PPI step-down protocol. RESULTS: Phase I identified that long-term PPI therapy was not indicated in 68.4% of patients. Phase II implementation demonstrated that 71.4% of patients were able to successfully step-down from PPI therapy in an average of 13 weeks with the use of alternative acid-suppression therapy. CONCLUSION: This study concluded that a majority of PPI prescriptions were not indicated for a duration of greater than or equal to 1 year. With the implementation of a pharmacist-driven PPI step-down protocol, a majority of patients were able to tolerate the PPI step-down with the use of alternative acidsuppression therapy.

Purpose of review To summarize current surgical and nonsurgical approaches to facial gender confirming surgery (FGCS) and highlight standards of care and areas of future research. Recent findings Gender nonconforming individuals may encounter considerable internal coping and external social stressors that may contribute to gender-associated dysphoria. FGCS provides patients the ability to align facial appearance with gender identity, using recently described advances in surgical and nonsurgical techniques. The majority of FGCS is performed on transwomen (individuals identifying as female), yielding the more common term of facial feminization surgery (FFS). Although no set protocols or standards are in place, certain procedures are commonly performed to alter sex-determining characteristics of the face, and further research may help define guidelines. As many training programs have minimal exposure to FGCS, promotion of transgender health awareness is paramount for diverse and inclusive surgical training. Summary Although demand for FGCS is increasing, there remains a need for improving surgical approaches, developing evidence-based care guidelines, and implementing education and awareness in training programs.

Aim: This study evaluated the impact of CYP3A5 genotype and other patient characteristics on sublingual (SL) tacrolimus exposure and compared the relationship with oral administration. Patients & methods: Tacrolimus concentrations were retrospectively collected for adult lung transplant recipients, who were genotyped for CYP3A5*3, CYP3A4*22, CYP3A7*1C, and POR*28. Regression analyses were performed to determine covariates that impacted the SL and oral tacrolimus concentration/dose ratios. Results: An interaction of CYP3A5 genotype and CYP3A inhibitor increased the SL concentration/dose, while cystic fibrosis decreased the SL concentration/dose. The oral concentration/dose was independently associated with these covariates and was increased by serum creatinine and number of tacrolimus doses. Conclusion: This study suggests personalized dosing strategies for tacrolimus likely need to consider characteristics beyond CYP3A5 genotype.

Purpose and Background Clopidogrel is a commonly used antiplatelet for the prevention of thromboembolic complications following several types of neuroendovascular procedures. Its widespread use stems from its relatively low cost, good efficacy, and safety profile. However, concern has emerged for the possibility that clopidogrel may induce severe, intolerable fatigue in a small subset of patients. Thus, the purpose of this study is to systematically investigate this phenomenon and to better characterize the demographic at risk. Methods We performed a dual-institution, 9-year, retrospective study of patients undergoing dual antiplatelet therapy with clopidogrel and aspirin for neuroendovascular procedures. Patients were included only if their response to clopidogrel was assessed by a VerifyNow P2Y12 (VNP) assay, which measures platelet inhibition using P2Y12 reactivity units (PRU). A hyper-response to clopidogrel is defined by a PRU ≤ 60. Patients were considered to have had clopidogrel-induced severe fatigue if 1) the onset of severe, intolerable fatigue followed the initiation of clopidogrel, 2) fatigue resolved or improved following a reduction in the dose of clopidogrel, 3) no hemorrhagic event occurred while on clopidogrel, and 4) fatigue could not be attributed to any other medical explanation. Results Clinical and demographic data were collected on 348 patients across 2 separate institutions. Five patients (1.4%) were identified as having met criteria for clopidogrel-induced severe fatigue. All 5 patients were female, ages 39-68. In addition to severe fatigue, they suffered from headache, nausea, vertigo, and dyspnea. Each patient had been taking clopidogrel for at least one week prior to the onset of symptoms, and VNP assays obtained while the patients were experiencing their symptoms revealed hyper-responses to clopidogrel, with PRU between 0-22. Four of these patients initially had an appropriate response to clopidogrel, with a PRU > 60 immediately prior to the intervention, and they did not report fatigue until later. In response to the severe, intolerable fatigue, clopidogrel was reduced by half, resulting in resolution or improvement of symptoms in all 5 patients. However, VNP assays returned persistently low values (0-16 PRU). One patient developed anemia after her symptoms had already resolved, but no additional complications were reported during the course of their therapy. Notably, 30% of patients (n = 103) demonstrated a hyper-response to clopidogrel on at least one VNP assay, but the vast majority of these patients did not suffer from severe fatigue. The rate of hyper-responses was similar across institutions and across genders. Conclusions Severe, intolerable fatigue is a rare but clinically significant side effect of clopidogrel. It is associated with a hyper-response to therapy as determined by a PRU value ≤ 60 on a VNP assay, but it appears that inhibition of platelet aggregation is merely epiphenomenal. Symptoms develop after an initial loading period and respond well to decreasing the dosage of clopidogrel. Only women were affected in our study, but this gender effect may reflect a sample bias as most of our patients were women. Disclosures D. Bass: None. C. Young: None. M. Park: None. D. Bass: None. K.

Background: SARS-CoV-2 infection is the cause of the respiratory illness COVID-19, which presents most frequently with respiratory symptoms SARS-CoV-2 cell entry requires interactions with ACE2 and TMPRSS2 on the surface of the host cell Cancer patients and, specifically, those with thoracic malignancies seem to experience poorer clinical outcomes Methods: We utilized bulk and single-cell transcriptional data from a combination of normal and malignant tissues and cells from aerodigestive and respiratory tracts to explore mechanisms governing the expression of ACE2 and TMPRSS2 Additionally, we determined the effect of EMT induction, ZEB1 modulation, and SARS-CoV-2 infection on ACE2 expression Results: Our bulk data suggests that aerodigestive and lung cancer models express a broad range of ACE2 and TMRPSS2, particularly in epithelial cells, and would serve as good models for studying SARS-CoV-2 infection We assessed the relationship between ACE2 and epithelial differentiation in numerous datasets, and found consistent positive correlations with transcriptional and microRNA signifiers of epithelial differentiation The miR-200 family – zinc finger E-box-binding homeobox 1 (ZEB1) pathway, which is an established regulator of EMT, also directly regulates ACE2 expression, likely via putative ZEB1 repressor sites located in the ACE2 promoter Furthermore, SARS-CoV-2 infection reduces ACE2 expression and shifts cells to a more mesenchymal phenotype with loss of EPCAM and upregulation of ZEB1 and other EMT-associated genes Conclusions: ACE2-positive cells are almost exclusively epithelial and unexpectedly rare, considering the devastating impact of this infection Following viral entry, SARS-CoV-2 infection induces molecular changes within the cells that are reminiscent of EMT, including increased ZEB1 ZEB1, in turn, appears to directly repress the expression of ACE2 This SARS-CoV-2-induced ACE2 deficiency, compounded by the downregulation of genes, including claudins, which play a critical role in restricting epithelial and endothelial permeability, exposes respiratory cells to increased risk of edema and acute respiratory distress syndrome (ARDS) Legal entity responsible for the study: The authors Funding: NIH/NCI R01-CA207295 (L A B ), NIH/NCI U01-CA213273 (L A B , J V H ), CCSG P30-CA01667 (L A B ), University of Texas SPORE in Lung Cancer P5-CA070907 (L A B , D L G , J V H , C M G ), the Department of Defense (LC170171;L A B ), Khalifa Bin Zayed Al Nahyan Foundation (C M G ), RP170067 (EMP), through generous philanthropic contributions to The University of Texas MD Anderson Lung Cancer Moon Shot Program and Andrew Sabin Family Fellowship, and The Rexanna Foundation for Fighting Lung Cancer Disclosure: C Gay: Research grant/Funding (self): Astra Zeneca J V Heymach: Advisory/Consultancy: AstraZeneca;Advisory/Consultancy: Boehringer Ingelheim;Advisory/Consultancy: Exelixis;Advisory/Consultancy: Genentech;Advisory/Consultancy: GlaxoSmithKline;Advisory/Consultancy: Guardant Health;Advisory/Consultancy: Hengrui;Advisory/Consultancy: Spectrum L A Byers: Advisory/Consultancy, Research grant/Funding (self): AstraZeneca;Advisory/Consultancy, Research grant/Funding (self): AbbVie;Advisory/Consultancy, Research grant/Funding (self): GenMab;Advisory/Consultancy: BergenBio;Advisory/Consultancy: Pharma Mar SA;Advisory/Consultancy, Research grant/Funding (self): Sierra Oncology;Advisory/Consultancy: Merck;Advisory/Consultancy: Bristol Myers Squibb;Advisory/Consultancy: Genentech;Advisory/Consultancy: Pfizer;Research grant/Funding (self): Tolero Pharmaceuticals All other authors have declared no conflicts of interest

Rising expenditures threaten healthcare sustainability. While transplant programs are typically considered profitable, transplant medications are expensive and frequently targeted for cost savings. This review aims to summarize available literature supporting cost-containment strategies used in solid organ transplant. Despite widespread use of these tactics, we found the available evidence to be fairly low quality. Strategies mainly focus on induction, particularly rabbit antithymocyte globulin (rATG), given its significant cost and the lack of consensus surrounding dosing. While there is higher-quality evidence for high single-dose rATG, and dose-rounding protocols to reduce waste are likely low risk, more aggressive strategies, such as dosing rATG by CD3+ target-attainment or on ideal-body-weight, have less robust support and did not always attain similar efficacy outcomes. Extrapolation of induction dosing strategies to rejection treatment is not supported by any currently available literature. Cost-saving strategies for supportive therapies, such as IVIG and rituximab also have minimal literature support. Deferral of high-cost agents to the outpatient arena is associated with minimal risk and increases reimbursement, although may increase complexity and cost-burden for patients and infusion centers. The available evidence highlights the need for evaluation of unique patient-specific clinical scenarios and optimization of therapies, rather than simple blanket application of cost-saving initiatives in the transplant population.

PURPOSE: Parents with metastatic cancer report unique concerns and challenges when discussing their illness with their minor children. Greater understanding of parents’ communication experiences can facilitate these discussions. This study aimed to describe the challenges, approaches, and decisions related to discussing prognosis among a sample of mothers with metastatic cancer. METHODS: We conducted a web-based cross-sectional survey assessing the psychosocial concerns of 224 women with metastatic cancer who had minor children. This analysis focused on participant responses to structured and open-ended questions addressing communication with their children. We used descriptive statistics to summarize responses to the structured questions and qualitative content analysis for responses to open-ended questions. RESULTS: Nearly 80% (n = 176) reported they had discussed their prognosis with at least one of their children; 79% identified at least one barrier to these discussions. The most common obstacles were participants’ uncertainty about their illness trajectory (43%) and emotional distress associated with these conversations (41%). Qualitative analyses revealed three principles that guided mothers’ communication decisions: commitment to honesty and protection; child developmental readiness; and beliefs about the right time. Approaches to discussing prognosis included total honesty, using the language of chronic illness, gradual disclosure, waiting for questions, and emphasizing hope, love, and reassurance. CONCLUSION: This study provides further evidence of the complexity and challenges of parental communication with their children about metastatic cancer. There is a need for both clinicians and researchers to identify, test, and implement evidence-based strategies to assist ill parents with their communication concerns.

BackgroundThe associations of geographic atrophy (GA) progression with systemic health status and medication use are unclear.MethodsWe manually delineated GA in 318 eyes in the Age-Related Eye Disease Study. We calculated GA perimeter-adjusted growth rate as the ratio between GA area growth rate and mean GA perimeter between the first and last visit for each eye (mean follow-up=5.3 years). Patients’ history of systemic health and medications was collected through questionnaires administered at study enrolment. We evaluated the associations between GA perimeter-adjusted growth rate and 27 systemic health factors using univariable and multivariable linear mixed-effects regression models.ResultsIn the univariable model, GA perimeter-adjusted growth rate was associated with GA in the fellow eye at any visit (p=0.002), hypertension history (p=0.03), cholesterol-lowering medication use (pConclusionsGA growth rate may be associated with the fellow eye status, cholesterol-lowering medication use, and diuretic use. These possible associations do not infer causal relationships, and future prospective studies are required to investigate the relationships further.

OBJECTIVE: To determine if high dose intravenous (IV) thiamine can prevent delirium during hospitalization following allogeneic HSCT. Secondarily, we evaluated the effects of high dose IV thiamine on thiamine levels and explored risk factors for delirium. METHODS: Randomized, double-blind, placebo-controlled trial in patients undergoing allogeneic HSCT at a U.S. academic medical center between October 2017 and March 2020. 64 participants were randomized 1:1 to thiamine 200 mg IV three times daily for 7 days or placebo. We used the Delirium Rating Scale to assess for delirium. Delirium incidence was compared between groups using the chi-square test. Group differences in time to onset and duration of delirium were compared using the Kaplan-Meier method. Fisher’s Exact and Wilcoxon Rank Sum tests were used to examine associations between pre-transplantation variables and delirium. RESULTS: 61 participants were analyzed. Delirium incidence (25% vs. 21%, Chi-square (df=1) = 0.12, p=0.73), time to onset, duration, and severity were not different between study arms. Immediately following the intervention, thiamine levels were higher in the thiamine arm (275 vs. 73 nmol/L, t-test (df=57) = 13.63, p

Objective To compare the incidence of oropharyngeal candidiasis (OC), or thrush, in renal transplant recipients receiving nystatin versus no antifungal prophylaxis. Methods This was a single-center, retrospective, non-inferiority study of adult renal transplant recipients (RTRs) who received nystatin for 30 days for OC prophylaxis (nystatin group) or no antifungal prophylaxis therapy (No PPX group). The primary outcome was the incidence of OC within 3 months post-transplant. Secondary outcomes included time to OC occurrence and severity of OC. The pre-specified non-inferiority margin was 10%. Results The incidence of OC within 3 months post-transplant among 257 RTRs was 7.8% (10/128) in the No PPX group and 4.7% (6/129) RTRs in the nystatin group, a risk difference of 3.2% (95% CI, -2.7% to 9.1%, non-inferiority P = .04). The median time to OC was 7.5 days (IQR 6.3-34.3 days) in the nystatin group and 9.5 days (IQR 5.3-30.5 days) in the No PPX group (P = .64). Esophageal candidiasis was observed in 10% (1/10) of RTRs with OC in the No PPX group compared to 16.7% (1/6) RTRs in the nystatin group (P = 1.00). All RTRs with OC achieved symptom resolution with fluconazole and/or nystatin. Two patients in the No PPX group required readmission for decreased oral intake, and OC was diagnosed and treated during their hospital day. Conclusions In this retrospective study of adult RTRs, the absence of antifungal prophylaxis demonstrated non-inferiority to 30-day nystatin prophylaxis at reducing the incidence of OC within 3 months of transplant. OC prophylaxis may not be warranted after renal transplant.

Leclercia adecarboxylata is an rare human pathogen, mostly affecting immunocompromised individuals or as one microbe in polymicrobial infections in immunocompetent patients. L. adecarboxylata is rarely isolated from the urinary tract. We describe a case of pan-sensitive L. adecarboxylata isolated from a polymicrobial urinary tract infection from an immunocompetent older adult with recently diagnosed bladder cancer.

Autism spectrum disorder (ASD) is associated with atypical brain development. However, the phenotype of regionally specific increased cortical thickness observed in ASD may be driven by several independent biological processes that influence the gray/white matter boundary, such as synaptic pruning, myelination, or atypical migration. Here, we propose to use the boundary sharpness coefficient (BSC), a proxy for alterations in microstructure at the cortical gray/white matter boundary, to investigate brain differences in individuals with ASD, including factors that may influence ASD-related heterogeneity (age, sex, and intelligence quotient). Using a vertex-based meta-analysis and a large multicenter structural magnetic resonance imaging (MRI) dataset, with a total of 1136 individuals, 415 with ASD (112 female; 303 male), and 721 controls (283 female; 438 male), we observed that individuals with ASD had significantly greater BSC in the bilateral superior temporal gyrus and left inferior frontal gyrus indicating an abrupt transition (high contrast) between white matter and cortical intensities. Individuals with ASD under 18 had significantly greater BSC in the bilateral superior temporal gyrus and right postcentral gyrus; individuals with ASD over 18 had significantly increased BSC in the bilateral precuneus and superior temporal gyrus. Increases were observed in different brain regions in males and females, with larger effect sizes in females. BSC correlated with ADOS-2 Calibrated Severity Score in individuals with ASD in the right medial temporal pole. Importantly, there was a significant spatial overlap between maps of the effect of diagnosis on BSC when compared with cortical thickness. These results invite studies to use BSC as a possible new measure of cortical development in ASD and to further examine the microstructural underpinnings of BSC-related differences and their impact on measures of cortical morphology.

Background Brachyury is a transcription factor overexpressed in chordoma and is associated with chemotherapy resistance and epithelial‐to‐mesenchymal transition. GI‐6301 is a recombinant, heat‐killed Saccharomyces cerevisiae yeast‐based vaccine targeting brachyury. A previous phase I trial of GI‐6301 demonstrated a signal of clinical activity in chordomas. This trial evaluated synergistic effects of GI‐6301 vaccine plus radiation. Materials and Methods Adults with locally advanced, unresectable chordoma were treated on a randomized, placebo‐controlled trial. Patients received three doses of GI‐6301 (80 × 107 yeast cells) or placebo followed by radiation, followed by continued vaccine or placebo until progression. Primary endpoint was overall response rate, defined as a complete response (CR) or partial response (PR) in the irradiated tumor site at 24 months. Immune assays were conducted to evaluate immunogenicity. Results Between May 2015 and September 2019, 24 patients enrolled on the first randomized phase II study in chordoma. There was one PR in each arm; no CRs were observed. Median progressive‐free survival for vaccine and placebo arms was 20.6 months (95% confidence interval [CI], 5.7–37.5 months) and 25.9 months (95% CI, 9.2–30.8 months), respectively. Hazard ratio was 1.02 (95% CI, 0.38–2.71). Vaccine was well tolerated with no vaccine‐related serious adverse events. Preexisting brachyury‐specific T cells were detected in most patients in both arms. Most patients developed T‐cell responses during therapy, with no difference between arms in frequency or magnitude of response. Conclusion No difference in overall response rate was observed, leading to early discontinuation of this trial due to low conditional power to detect statistical difference at the planned end of accrual. Implications for Practice Chordoma is a rare neoplasm lacking effective systemic therapies for advanced, unresectable disease. Lack of clinically actionable somatic mutations in chordoma makes development of targeted therapy quite challenging. While the combination of yeast‐brachyury vaccine (GI‐6301) and standard radiation therapy did not demonstrate synergistic antitumor effects, brachyury still remains a good target for developmental therapeutics in chordoma. Patients and their oncologists should consider early referral to centers with expertise in chordoma (or sarcoma) and encourage participation in clinical trials., The use of a therapeutic cancer vaccine that stimulates the immune system to fight brachyury‐expressing cancer cells is a promising alternative to targeted molecular therapies. This article evaluates the concurrent use of a yeast‐brachyury vaccine in combination with radiation therapy in patients with advanced or metastatic chordoma.

Background Biodegradable polymer drug-eluting stents (BP-DES) has been developed to overcome the potential drawbacks of the first-generation durable polymer drug-eluting stents (DP-DES). However, it is still under debate whether BP-DES is associated with superior efficacy and safety over DP-DES. Purpose We sought to compare the effects of BP-DES and DP-DES in patients with coronary artery disease. Methods We performed systematic review and a meta-analysis of randomized controlled trials comparing BP-DES and DP-DES on clinical outcomes in patients with coronary artery disease using CE-mark approved drug-eluting stents (DES) with at least 1-year follow-up. We included 32 studies involving 39,686 patients (BP-DES: 21,439 patients, and DP-DES: 18,247 patients). Primary outcome measure was target vessel failure (TVF; equivalent to the composite of cardiac death, target-vessel myocardial infarction, or ischemia-driven target vessel revascularization). We performed subgroup analysis according to the DP-DES generations (newer-generation DP-DES: 15,179patients, and first-generation DP-DES: 3,068 patients), and the effects of newer-generation DP-DES was compared with the BP-DES according to the BP-DES strut thickness (Ultra-thin strut [ Results The odds for TVF was not significantly different between the BP-DES group and the DP-DES group in the entire study population (odds ratio [OR] 0.96, 95% confidence interval [CI] [0.90–1.02], P=0.20). The odds for TVF was significantly low in the BP-DES group relative to the first-generation DP-DES group, however the odds were comparable between the BP-DES group and the newer-generation DP-DES group (BP-DES versus first-generation DP-DES: OR 0.82, 95% CI [0.73–0.92], P Conclusions In this meta-analysis of randomized controlled trials evaluating clinical outcomes, there was no significant differences between BP-DES and DP-DES. We found beneficial effects of BP-DES relative to the first-generation DP-DES, however, there was no statistical differences between BP-DES and newer-generation DP-DES, irrespective of the BP-DES strut thickness.

Neurological immune-related adverse events (irAEs) are rare toxicities that occur following immune checkpoint inhibitor therapy. We propose that patients with thymic malignancies and graft-versus-host disease (GVHD) are predisposed to irAEs. We present two asymptomatic patients, one with thymoma and another with GVHD, who developed abnormal brain MRIs after treatment with programmed cell death protein 1 inhibitors. The first patient, with thymic cancer and thymoma, developed pontine enhancing MRI lesions following treatment with pembrolizumab. The second patient, with prior GVHD, developed pachymeningeal enhancement following treatment with nivolumab. IrAEs with abnormal MRI studies, despite asymptomatology, have significant impact on the treatment strategy for these patients.

OBJECTIVE/HYPOTHESIS For patients undergoing microvascular free tissue transfer (MFTT), we evaluated risk factors and financial implications of operating room (OR) take-back procedures. STUDY DESIGN Retrospective review at a tertiary care center. METHODS Patients who underwent MFTT for head and neck reconstruction from 2011 to 2018 were identified. We compared hospital length of stay and overall costs associated with OR take-back procedures. Multivariable regression analysis evaluated factors associated with OR take-backs during the same hospitalization. RESULTS A total of 727 free flaps were reviewed, and 70 OR take-backs (9.6%) were identified. Mean total length of stay (LOS) in the ICU was 3.4 days versus 6.7 days for non-take-back and take-back flaps, respectively (P

ObjectiveAdvanced cancer patients who are parents of minor children experience heightened psychosocial distress. Oncology social workers (OSWs) are essential providers of psychosocial support to parents with advanced cancer. Yet, little is known about the experiences and approaches of OSWs in addressing these patients’ unique needs. The purpose of this study was to characterize the attitudes, practice behaviors, and training experiences of OSWs who provide psychosocial care for advanced cancer patients with minor children.MethodForty-one OSWs participated in a cross-sectional survey addressing multiple facets of their psychosocial care for parents with advanced cancer. The five assessed domains of psychosocial support were communication support, emotional support, household support, illness and treatment decision-making support, and end-of-life planning.ResultsParticipants reported greatest confidence in counseling patients on communication with children about illness and providing support to co-parents about parenting concerns. OSWs reported less confidence in counseling parents on end-of-life issues and assisting families with non-traditional household structures. The majority of participants reported needing more time in their clinical practice to sufficiently address parents’ psychosocial needs. Nearly 90% of participants were interested in receiving further training on the care of parents with advanced cancer.Significance of resultsTo improve the care of parents with advanced cancer, it is critical to understand how the psychosocial oncology workforce perceives its clinical practice needs. Study findings suggest an opportunity for enhanced training, particularly with respect to end-of-life needs and in response to the changing household structure of American families.
