Anatomical classification of canine congenital extrahepatic portosystemic shunts based on CT angiography: A SVSTS and VIRIES multi-institutional study in 1082 dogs.

Canine congenital extrahepatic portosystemic shunt (EHPSS) morphologies have not been fully elucidated. The goal of this retrospective, multi-institutional study was to use CT angiography to create an anatomical-based nomenclature system for canine congenital EHPSS. These shunt morphologies were then evaluated to identify any significant association with patient age, sex, breed, weight, or subjective portal perfusion score. Data collected respectively from the SVSTS and VIRIES list-serves included patient DOB, sex, breed, weight, CT date, and reported diagnosis. A single author (C.W.) viewed all CT scans and classified shunts based on the shunt portal vessel(s) of origin, the shunt systemic vessel(s) of insertion, and any substantial portal vessels contributing to the shunt. Additionally, hepatic portal perfusion was subjectively scored between one (poor/none) and five (good/normal) based on the caliber of the intrahepatic portal veins. A total of 1182 CT scans were submitted from 13 different institutions. Due to exclusion criteria, 100 (8.5%) were removed, leaving 1082 CT scans to be included. Forty-five different EHPSS anatomies were identified with five classifications accounting for 85% of all shunts (left gastric-phrenic [27%], left gastric-azygos [19%], left gastric-caval [15%], aberrant left gastric-caval with right gastric vein [12%], and aberrant left gastric-caval with right gastric vein and short gastric vein [11%]). Shunt origin involved the left gastric vein in 95% of the described classifications. Significant differences were identified among the five most common shunt types with respect to age at the time of the CT scan (P < .001), sex (P = .009), breed (P < .001), weight (P < .001), and subjective portal perfusion score (P < .001). An anatomical classification system for canine EHPSS may enable improved understanding, treatment comparisons, and outcome prediction for these patients.

Testing the Effects of Individual Residents' Retrieval Practice on Standardized Examination Scores.

Background: Residents have limited time and much to learn. Retrieval practice-studying using exam-style review questions-is a powerful educational tool for aggregate groups of learners, but it has not been tested for individual graduate medical education (GME) trainees. Methods: We conducted a retrospective observational study examining how individual residents' self-directed retrieval practice affected their learning. We used linear regression models to compare the number of exam-style multiple-choice practice questions each resident answered per year to their scores on annual In-Training Exams (ITE). Results: We found that the higher a resident's ITE score was at the start of a year, the fewer practice questions they answered that year for both first- (p = 0.023) and second-year (p = 0.020) trainees. Then, the more questions a resident answered in a year, the more their ITE score increased over that year for both first- and second-year trainees (p = 0.026 and 0.025, respectively). Residents' prior ITE scores also independently predicted their subsequent ITE scores (p = 0.024 in the first and 0.007 in the second year), and the effect of their baseline scores was larger than the effect of the number of practice questions they answered. Conclusions: Individual residents' prior exam scores significantly predict their future exam scores, and their independent retrieval practice using exam-style review questions also significantly predicts the annual improvement in their scores. These findings add to the growing evidence supporting retrieval practice in GME, and they can inform individualized educational coaching for GME trainees.

Racial Disparities in Endometrial Cancer Clinical Trial Representation: Exploring the Role of Eligibility Criteria.

OBJECTIVE: This study aimed to determine whether Black patients with recurrent endometrial cancer were more likely than White patients to be ineligible for a recently published clinical trial due to specific eligibility criteria. METHODS: Patients with recurrent or progressive endometrial cancer diagnosed from January 2010 to December 2021 who received care at a single institution were identified. Demographic and clinicopathologic information was abstracted and determination of clinical trial eligibility was made based on 14 criteria from the KEYNOTE-775 trial. Characteristics of the eligible and ineligible cohorts were compared, and each ineligibility criterion was evaluated by race. RESULTS: One hundred seventy-five patients were identified, 89 who would have met all inclusion and no exclusion criteria for KEYNOTE-775, and 86 who would have been ineligible by one or more exclusion criteria. Patients in the ineligible cohort were more likely to have lower BMI (median 26.5 vs. 29.2, P <0.001), but were otherwise similar with regard to insurance status, histology, and stage at diagnosis. Black patients had 33% lower odds of being eligible (95% CI: 0.33-1.34) and were more likely to meet the exclusion criterion of having a previous intestinal anastomosis, but the result was not statistically significant. If this criterion were removed, the racial distribution of those ineligible for the trial would be more similar (46.4% Black vs. 42.2% White). CONCLUSIONS: Clinical trial eligibility criteria may contribute to the underrepresentation of racial groups in clinical trials, but other factors should be explored. Studies to quantify and lessen the impact of implicit bias are also needed.

Characterizing "collateral damage" in men and women with metastatic breast cancer (mBC) from diverse racial and ethnic backgrounds in New York City.

PURPOSE: Patients from diverse racial, ethnic, and socio-economic backgrounds may be particularly vulnerable to experiencing undue social and financial burdens ("collateral damage") from a metastatic breast cancer (mBC) diagnosis; however, these challenges have not been well explored in diverse populations. METHODS: From May 2022 to May 2023, English- or Spanish-speaking adults with mBC treated at four New York-Presbyterian (NYP) sites were invited to complete a survey that assessed collateral damage, social determinants of health, physical and psychosocial well-being, and patient-provider communication. Fisher's exact and the Kruskal-Wallis rank-sum tests assessed differences by race and ethnicity. RESULTS: Of 87 respondents, 14% identified as Hispanic, 28% non-Hispanic Black (NHB), 41% non-Hispanic White (NHW), 7% Asian American Pacific Islander (AAPI), and 10% other/multiracial. While 100% of Hispanic, NHW, and AAPI participants reported stable housing, 29% of NHB participants were worried about losing housing (p = 0.002). Forty-two percent of Hispanic and 46% of NHB participants (vs. 8%, NHW and 0%, AAPI, p = 0.005) were food insecure; 18% of Hispanic and 17% of NHB adults indicated lack of reliable transportation in the last year (vs. 0%, NHW/AAPI, p = 0.033). Participants were generally satisfied with the quality of communication that they had with their healthcare providers and overall physical and mental well-being were modestly poorer relative to healthy population norms. CONCLUSIONS: In our study, NHB and Hispanic mBC patients reported higher levels of financial concern and were more likely to experience food and transportation insecurity compared to NHW patients. Systematically connecting patients with resources to address unmet needs should be prioritized to identify feasible approaches to support economically vulnerable patients following an mBC diagnosis.

Preoperative parameters (signalment, digital radiography, urinalysis, urine microbiological culture) and novel algorithm improve prediction of canine urocystolith composition.

OBJECTIVE: To determine the accuracy of 4 preoperative parameters (signalment, urinalysis, urine microbiological culture, and digital radiography) in predicting urocystolith composition, compare accuracy between evaluators of varying clinical experience and a mobile application, and propose a novel algorithm to improve accuracy. ANIMALS: 175 client-owned dogs with quantitative analyses of urocystoliths between January 1, 2012, and July 31, 2020. METHODS: Prospective experimental study. Canine urocystolith cases were randomly presented to 6 blinded "stone evaluators" (rotating interns, radiologists, internists) in 3 rounds, each separated by 2 weeks: case data alone, case data with a urolith teaching lecture, and case data with a novel algorithm. Case data were also entered into the Minnesota Urolith Center mobile application. Prediction accuracy was determined by comparison to quantitative laboratory stone analysis results. RESULTS: Prediction accuracy of evaluators varied with experience when shown case data alone (accuracy, 57% to 82%) but improved with a teaching lecture (accuracy, 76% to 89%) and further improved with a novel algorithm (accuracy, 93% to 96%). Mixed stone compositions were the most incorrectly predicted type. Mobile application accuracy was 74%. CLINICAL RELEVANCE: Use of the 4 preoperative parameters resulted in variable accuracy of urocystolith composition predictions among evaluators. The proposed novel algorithm improves accuracy for all clinicians, surpassing accuracy of the mobile application, and may help guide patient management.

Racial and Ethnic Variation in Receipt and Intensity of Active Surveillance for Older Patients With Localized Prostate Cancer.

INTRODUCTION: The use of active surveillance (AS) for prostate cancer is increasing, and racial disparities have been identified in its implementation. We investigated differences by race and ethnicity in the utilization and intensity of AS by race and ethnicity among older men with low- and favorable intermediate-risk prostate cancer, with particular focus on the integration of multiparametric MRI (mpMRI) into AS protocols. METHODS: Using the Surveillance, Epidemiology, and End Results and Medicare fee-for-service linked database, we identified a cohort of men diagnosed between 2010 and 2017 with low- or favorable intermediate-risk prostate cancer. The odds of receiving AS were compared by patient race and ethnicity using multivariable logistic regression models, while the rates of usage of PSA tests, biopsy, and mpMRI within 2 years of diagnosis among men on AS were assessed using multivariable Poisson regression models. RESULTS: Our cohort included 33,542 men. The proportion of men with low-risk disease who underwent AS increased from 29.5% in 2010 to 51.7% in 2017, while the proportion among men with favorable intermediate disease grew from 11.4% to 17.2%. Hispanic (odds ratio [OR] = 0.68, 95% CI 0.58-0.79) and non-Hispanic Black men (OR = 0.78, 95% CI 0.68-0.89) were less likely to receive AS than non-Hispanic White men for low-risk disease, while non-Hispanic Black men were more likely to receive AS for favorable intermediate disease (OR = 1.21, 95% CI 1.04-1.39). Non-Hispanic Black men receiving AS underwent prostate MRI at a lower rate compared to non-Hispanic White men, regardless of whether they had low-risk (incidence rate ratio = 0.77, 95% CI 0.61-0.97) or favorable intermediate-risk (incidence rate ratio = 0.61, 95% CI 0.44-0.83) disease, respectively. CONCLUSIONS: The overall adoption of AS for low-risk prostate cancer increased among Medicare fee-for-service beneficiaries. However, a significant disparity exists for non-Hispanic Black men, as they exhibit lower rates of AS utilization. Moreover, non-Hispanic Black men are less likely to have access to novel technologies, such as mpMRI, as part of their AS protocols.

Anatomical classification of feline congenital extrahepatic portosystemic shunts based on CT angiography: A SVSTS and VIRIES multi-institutional study in 231 cats.

The prevalence of anatomical-based subtypes of feline congenital extrahepatic portosystemic shunts (EHPSS) has not been completely elucidated. The goal of this study was to use CT angiography to create an anatomical-based nomenclature system for feline congenital EHPSS. Additionally, subjective portal perfusion scores were generated to determine if intrinsic portal vein development was associated with different shunt conformations or patient age at the time of CT. The SVSTS and VIRIES list services were used to recruit cases. Data collected included patient DOB, gender, breed, weight, CT date, and reported diagnosis. Shunts were classified based upon (1) the shunt portal vessel(s) of origin, (2) the shunt systemic vessel(s) of insertion, and (3) any substantial portal vessels contributing to the shunt. Additionally, hepatic portal perfusion was subjectively scored between 1 (poor/none) and 5 (good/normal) based on the caliber of the intrahepatic PVs. A total of 264 CT scans were submitted from 29 institutions. Due to exclusion criteria, 33 (13%) were removed, leaving 231 CT scans to be included. Twenty-five different EHPSS anatomies were identified with five classifications accounting for 78% of all shunts (LGP [53%], LGC-post [11%], LCG [7%], LGC-pre [4%], and PC [4%]). Shunt origin involved the left gastric vein in 75% of the described classifications. Significant differences were identified among the five most common shunt types with respect to age at the time of CT scan (P = .002), breed (P < .001), and subjective portal perfusion score (P < .001). This refined anatomical classification system for feline EHPSS may enable improved understanding, treatment comparisons, and outcome prediction for cats with these anomalies.

No Racial Disparities Observed Using Point-of-Care Genetic Counseling and Testing for Endometrial and Ovarian Cancer in a Diverse Patient Population: A Retrospective Cohort Study.

We investigated genetic counseling and testing rates for patients with gynecologic malignancy at a tertiary care center with a large minority population. Our retrospective cohort included newly diagnosed epithelial ovarian, fallopian tube, peritoneal, or endometrial cancer patients between January 2014 and June 2022. For endometrial cancer, 373 patients were identified. A total of 207 (55%) patients were screened using mismatch repair immunohistochemistry (MMR IHC). A total of 82 (40%) had MMR deficiencies on IHC. Of these, 63 (77%) received genetic counseling. A total of 62 (98%) underwent genetic testing, and ultimately, 7 (11%) were diagnosed with Lynch syndrome (LS). The overall rate of LS was 1.9%. MMR IHC testing increased steadily, reaching 100% in 2022. For ovarian cancer, 144 patients were identified. A total of 104 (72%) patients received genetic counseling, and 99 (95%) underwent genetic testing. Rates were not influenced by race, ethnicity, insurance type, or family history of cancer. They were significantly different by cancer stage (p < 0.01). The proportion of patients who received genetic counseling increased from 47% in 2015 to 100% in 2022 (p < 0.01). Most counseling was performed by a gynecologic oncologist (93%) as opposed to a genetic counselor (6.7%). Overall, 12 (8.3%) patients were BRCA+. High rates of counseling and testing were observed with few disparities.

Racial and Ethnic Differences in Psychosocial Care Use Among Adults With Metastatic Breast Cancer: A Retrospective Analysis Across Six New York City Health Systems.

PURPOSE: A metastatic breast cancer (mBC) diagnosis can affect physical and emotional well-being. However, racial and ethnic differences in receipt of outpatient psychosocial care and supportive care medications in adults with mBC are not well described. METHODS: Adults with mBC were identified in the INSIGHT-Clinical Research Network, a database inclusive of >12 million patients receiving care across six New York City health systems. Outpatient psychosocial care was operationalized using Common Procedure Terminology codes for outpatient psychotherapy or counseling. Psychosocial/supportive care medications were defined using Rx Concept Unique Identifier codes. Associations between race/ethnicity and outpatient care and medication use were evaluated using logistic regression. RESULTS: Among 5,429 adults in the analytic cohort, mean age was 61 years and <1% were male; 53.6% were non-Hispanic White (NHW), 21.4% non-Hispanic Black (NHB), 15.9% Hispanic, 6.1% Asian/Native Hawaiian/Pacific Islander (A/NH/PI), and 3% other or unknown. Overall, 4.1% had ≥one outpatient psychosocial care visit and 63.4% were prescribed ≥one medication. Adjusted for age, compared with NHW, Hispanic patients were more likely (odds ratio [OR], 2.14 [95% CI, 1.55 to 2.92]) and A/NH/PI patients less likely (OR, 0.35 [95% CI, 0.12 to 0.78]) to have an outpatient visit. NHB (OR, 0.59 [95% CI, 0.51 to 0.68]) and Asian (OR, 0.36 [95% CI, 0.29 to 0.46]) patients were less likely to be prescribed medications. CONCLUSION: Despite the prevalence of depression, anxiety, and distress among patients with mBC, we observed low utilization of psychosocial outpatient care. Supportive medication use was more prevalent, although differences observed by race/ethnicity suggest that unmet needs exist.

Omission and Commission in Morally Injurious Experiences Among COVID-19 Health Care Professionals.

Objective: To produce a qualitative description of the impact of moral injury on medical providers during the COVID-19 pandemic.Methods: A convergent mixed-methods study design was used to explore experiences of health care workers during the first 12 months of the COVID-19 pandemic. Participants completed the Moral Injury Symptom Scale-HP (MISS-HP) and a 60-minute interview, in which they described their work experiences from March 2020 through January 2021. The study was conducted between May 2021 and August 2021.Results: Eight physicians and 6 nurses were interviewed. Most participants (71%) worked in the emergency department, while 29% worked in the medical intensive care unit (MICU). MISS-HP scores were 49 on average and ranged from 29 to 73. Among the demographic groups, MICU participants scored the highest (56) and men scored the lowest (40). There were no significant differences in scores between any demographic group. The analysis of interview data showed how omissions and commissions in one's professional duties created internal conflicts, which were inextricably linked to a deeper sense of feelings of guilt and blame around experiences of betraying or being betrayed and an inability to uphold one's moral values.Conclusions: The pandemic upended a previously reliable and imperceptible experience of a background of safety, in which the provision of both material resources and human presence was expected without question. Future directions generated from this study might examine the role of dependency on leadership structures and relationships with self and others that create the conditions for moral injury.Prim Care Companion CNS Disord 2024;26(1):23m03651.

Rapid Critical Care Training for Nurses Deployed to Intensive Care Units During the COVID-19 Surge.

BACKGROUND: During the first COVID-19 pandemic wave, non-intensive care unit (non-ICU) nurses were deployed to temporary ICUs to provide critical care for the patient surge. A rapid critical care training program was designed to prepare them to care for patients in either temporary or permanent ICUs. OBJECTIVE: To evaluate the effectiveness of this training program in preparing non-ICU nurses to provide critical care for COVID-19 patients in temporary ICUs. METHODS: A survey was used to evaluate the impact of rapid critical care training on nurses' critical care skills and compare the experiences of nurses deployed to temporary versus permanent ICUs. Data were analyzed with χ2 and Spearman ρ tests with α = .05. RESULTS: Compared with nurses in other locations, nurses deployed to temporary ICUs were less likely to report improved capability in managing mechanical ventilation; infusions of sedative, vasoactive, and paralytic agents; and continuous renal replacement therapy. Nurses in temporary ICUs also reported being less prepared to care for critically ill patients (all P < .05). CONCLUSIONS: The rapid training program provided basic critical care knowledge for nurses in temporary ICUs, but experiences differed significantly between those deployed to temporary versus permanent ICUs. Although participants believed they provided safe care, nurses with no critical care experience cannot be expected to learn comprehensive critical care from expedited instruction; more formal clinical support is needed for nurses in temporary ICUs. Rapid critical care training can meet emergency needs for nurses capable of providing critical care.

Epidemiology of anticoagulation for children supported by extracorporeal membrane oxygenation in the United States: A Pediatric Hospital Information System database study.

INTRODUCTION: Due to the risk of thrombosis, nearly all children supported by extracorporeal membrane oxygenation (ECMO) receive systemic anticoagulation. While heparin has traditionally been used, there are reports of increased use of direct thrombin inhibitors. We sought to describe the use of anticoagulation in children supported by ECMO in the United States using a large administrative database. METHODS: We performed a retrospective cohort study of children supported by ECMO within the Pediatric Health Information System (PHIS) database. Pediatric encounters involving ECMO from 2012 to 2020 were identified. Data regarding demographics, diagnoses, anticoagulation, complications, and outcomes were extracted for eligible encounters. RESULTS: Eleven thousand five hundred ninety-five encounters that involved ECMO were identified. Fifty-four percent were male with an age range of 0-17 years and a median (IQR) age of 0 (0-2) years. Unfractionated heparin (UFH) only was used in 94% (95% CI: 93.6-94.5%) of encounters and UFH followed by bivalirudin in 5% (95% CI: 4.3-5.1%) of cases. There was a significant difference in the use of bivalirudin from 2012 to 2020 (p < 0.001). Differences in anticoagulation regimens were observed between infants and children (p = 0.004) and between those with and without cardiac indications for ECMO (p < 0.001). Four percent (95% CI: 4.1-4.8%) of encounters were associated with diagnostic coding for thrombosis and differences in occurrence of thrombosis were observed between different anticoagulant regimens (p < 0.001). CONCLUSIONS: Though the majority of children on ECMO in the United States receive heparin anticoagulation, there is an increase in use of direct thrombin inhibitors. Prospective studies must evaluate the efficacy of different anticoagulants in this patient population.

Timing to Surgery and Lymph Node Upstaging in Gastric Cancer: An NCDB Analysis.

BACKGROUND: Prior studies have shown tumor specificity on the impact of longer time interval from diagnosis to surgery, however in gastric cancer (GC) this remains unclear. We aimed to determine if a longer time interval from diagnosis to surgery had an impact on lymph node (LN) upstaging and overall survival (OS) outcomes among patients with clinically node negative (cN0) GC. PATIENTS AND METHODS: Patients diagnosed with cN0 GC undergoing surgery between 2004-2018 were identified in the National Cancer Database (NCDB) and divided into intervals between time of diagnosis and surgery [short interval (SI): ≥ 4 days to < 8 weeks and long interval (LI): ≥ 8 weeks]. Multivariable regression analysis evaluated the independent impact of surgical timing on LN upstaging and a Cox proportional hazards analysis and Kaplan-Meier curves evaluated survival outcomes. RESULTS: Of 1824 patients with cN0 GC, 71.8% had a SI to surgery and 28.1% had a LI to surgery. LN upstaging was seen more often in the SI group when compared to LI group (82% versus 76%, p = 0.004). LI to surgery showed to be an independent factor protective against LN upstaging [adjusted odds ratio = 0.62, 95% CI: (0.39-0.99)]. Multivariate Cox regression analysis indicated that time to surgery was not associated with a difference in overall survival [hazard ratio (HR) = 0.91, 95% CI: (0.71-1.17)], however uncontrolled Kaplan-Meier curves showed OS difference between the SI and LI to surgery groups (p = 0.037). CONCLUSION: Timing to surgery was not a predictor of LN upstaging or overall survival, suggesting that additional medical optimization in preparation for surgery and careful preoperative staging may be appropriate in patients with node negative early stage GC without affecting outcomes.

Mammography screening beliefs and barriers through the lens of Black women during the COVID-19 pandemic.

BACKGROUND: Mammography is an effective screening tool that leads to decreased breast cancer mortality, yet minority women continue to experience barriers. The coronavirus disease 2019 (COVID-19) pandemic has been proven to have negatively affected minority communities, yet its effect on mammography screening habits in Black women is uncertain. The purpose of this study was to evaluate breast cancer mammography screening habits and barriers for Black women in two northeast communities amid the COVID-19 pandemic. METHODS: The study participants were Black women aged 40 years or older who were recruited from community outreach initiatives. Study coordinators conducted telephone surveys to determine mammography screening behaviors, perceptions, and psychosocial factors. RESULTS: Two hundred seventy-seven surveys were completed. Two hundred fifty-six patients who reported ever having a mammogram became the study population of interest. One hundred seventy-four of these patients (68%) reported having a mammogram within the past year (nondelayed), and 82 (32%) had a mammogram more than a year ago (delayed). Only thirty-one of the delayed participants (37.8%) had private insurance. There was a significant difference in the mean score for mammography screening perceived barriers for nondelayed participants (mean = 9.9, standard deviation [SD] = 3.6) versus delayed participants (mean = 11.2, SD = 4.3, p = .03). There was also a significant difference in the mean score when they were asked, "How likely is it that 'other health problems would keep you from having a mammogram'?" (p = .002). CONCLUSIONS: Barriers to mammography screening for Black women during the COVID-19 era include insurance, competing health issues, and perceptions of screening. Community outreach efforts should concentrate on building trust and collaborating with organizations to improve screening despite the COVID-19 pandemic.

Psychosocial well-being during the COVID-19 pandemic among women with and without breast cancer.

OBJECTIVE: Treatment delays in combination with general social distancing practices to reduce transmission may have negative impacts on the mental health of women with breast cancer who may need more social and emotional support. We sought to elucidate the psychosocial effects of the COVID-19 pandemic among women with and without breast cancer in New York City. METHODS: We conducted a prospective cohort study among women aged 18+ across the spectrum of breast health care at New York Presbyterian (NYP)-Weill Cornell, NYP-Brooklyn Methodist Hospital and NYP-Queens. Women were contacted between June and October 2021 to assess their self-reported depression, stress, and anxiety during the COVID-19 pandemic. We compared women who were recently diagnosed, those with a history of breast cancer, and women without cancer whose other health visits were delayed during the pandemic. RESULTS: There were 85 women who completed the survey. Breast cancer survivors (42%) were the least likely to report a delay in care due to COVID compared to breast cancer patients who were recently diagnosed (67%) and women without cancer (67%). Compared to women without cancer and breast cancer survivors, women recently diagnosed with breast cancer reported higher levels of anxiety and depression with a statistically significant difference in perceived stress. CONCLUSIONS: Our findings highlight the need to identify and risk-stratify patients facing a new breast cancer diagnosis in and around the COVID-19 pandemic who may benefit from additional resources to mitigate the adverse impacts of the pandemic and a breast cancer diagnosis on psychosocial health.

Epidemiology of Platelet Transfusions in Hospitalized Children: A Pediatric Hospital Information System Database Study.

OBJECTIVES: To describe the epidemiology and complications of platelet transfusions among hospitalized pediatric patients during 2010 to 2019. METHODS: We performed a retrospective cohort study of hospitalized children within the Pediatric Health Information System database. Pediatric encounters receiving at least one platelet transfusion during hospitalization from 2010 to 2019 were identified. Data regarding demographics, diagnoses, procedures required during hospitalization, complications, and outcomes were extracted for eligible encounters. RESULTS: Within the Pediatric Health Information System database, 6 284 264 hospitalizations occurred from 2010 to 2019. A total of 244 464 hospitalizations required at least one platelet transfusion, yielding a prevalence of 3.89% (95% confidence interval [CI], 3.87%-3.91%). Transfusion prevalence did not change significantly across the decade (P value = .152). Two-thirds of children receiving platelet transfusions were in their first 6 years of life, and the majority identified as male (55%). Recipients most commonly had diseases of the circulatory system (21%, 52 008 of 244 979), perinatal disorders (16%, 38 054 of 244 979), or diseases of the hematologic/immune systems (15%, 37 466 of 244 979). When adjusted for age, support by extracorporeal membrane oxygenation, mechanical ventilation, surgical intervention, and diagnostic category, the odds of thrombosis, infection, and mortality increased by 2% (odds ratio [OR], 1.02; 95% CI, 1.016-1.020), 3% (OR, 1.03; 95% CI, 1.028-1.033), and 7% (OR, 1.07; 95% CI, 1.067-1.071), respectively, with each additional transfusion. CONCLUSIONS: The prevalence of platelet transfusions among pediatric inpatients remained consistent across the decade. Our finding that increasing numbers of transfusions may be associated with elevated morbidity and mortality is consistent with other observation and experimental studies, highlighting the need to be thoughtful in weighing risks and benefits when prescribing repeated platelet transfusions to hospitalized children.

Ten-year conditional probability of survival for patients with ovarian cancer: A new metric tailored to Long-term survivors.

OBJECTIVES: We assessed a conditional probability of survival (CPS) model to determine the probability of living 10 years after ovarian cancer diagnosis after having already survived 5 years. METHODS: We identified patients newly diagnosed with high-grade epithelial ovarian cancer from 1/1/2001-12/31/2009 and treated at our institution. Patients with <3 years follow-up were excluded. CPS was defined as the probability of surviving additional years (y) based on the condition a patient had already survived a given time (x): S(x + y)/S(x). Confidence intervals were estimated using a variation of Greenwood's formula. RESULTS: Of 916 patients meeting inclusion criteria, 473 (52%) were diagnosed from 2001 to 2005 and 443 (48%) from 2006 to 2009. Median age at diagnosis was 60 years (range, 25-95). The conventional 10-year OS rate for all patients was 29% (95% CI: 26%-32%)-75% (95% CI: 68%-82%) for stage I/II disease, 22% (95% CI: 19%-26%) for stage III, and 6.9% (95% CI: 3.9%-12%) for stage IV. For patients <65 years, the 10-year CPS for 5-year survivors was 65% (95% CI: 59%-70%); for those ≥65 years, it was 48% (95% CI: 38%-57%). For patients <65 years, the 10-year CPS for 5-year survivors by stage was: stage I/II, 89% (95% CI: 81%-94%); stage III, 58% (95% CI: 50%-66%); and stage IV, 26% (95% CI: 12%-42%). For patients ≥65 years, rates by stage were 78% (95% CI: 53%-91%), 42% (95% CI: 30%-53%), and 29% (95% CI: 7%-56%), respectively. CONCLUSIONS: For long-term survivors with high-grade epithelial ovarian cancer, CPS provides better prediction of survival than conventional methods.

Access to cardiac PET/CT by sarcoidosis patients and cost-effectiveness analysis of cardiac PET/MR compared to the standard of care.

IMPORTANCE: Cardiac sarcoidosis is associated with a high mortality rate. Given multiple barriers to obtaining cardiac PET imaging, we suspect individuals with access to this imaging modality are not representative of the Sarcoid patient population, which in the United States are predominantly Black females. OBJECTIVE: To evaluate the demographics of patients with cardiac PET access and the cost-effectiveness of cardiac PET/MR imaging relative to standard of care. DESIGN: This is a retrospective, observational study. The demographic information of patients with suspected cardiac sarcoidosis and cardiac PET/CT imaging within a national registry of sarcoidosis were reviewed (n = 4561). An individual-level, continuous, time-state transition model was used for the evaluation of long-term cost-effectiveness for the combined cardiac PET/MR compared to standard of care cardiac MR followed by cardiac PET/CT. RESULTS: Patients who underwent cardiac PET in the national registry had 88.35% higher odds of being male (p < 0.001) and 43.82% higher odds of being White (p = 0.003) than their counterparts who did not have cardiac PET imaging. Combined cardiac PET/MR had overall lower total lifetime costs ($8761 vs $10,777) and overall improved expected quality of life-years compared to the standard of care (0.77 vs 0.69). CONCLUSION AND RELEVANCE: The findings suggest that patients with access to cardiac PET/CT are not representative of the patient population most likely to have cardiac sarcoidosis in this limited study evaluation. Universal insurance coverage should be considered for Cardiac PET imaging as same day cardiac PET and MR imaging has potential long-term cost and quality of life benefit.
