Retrospective assessment of ophthalmic disease development in domestic dogs and cats when hospitalised with tick paralysis caused by Ixodes holocyclus.

OBJECTIVE: To investigate the incidence and predisposing factors leading to the development of corneal ulcers and the loss of a palpebral reflex in hospitalised canine and feline patients with tick paralysis (TP). ANIMALS STUDIED: A total of 102 dogs and 100 cats retrospectively were assessed from previously hospitalised patients. METHODS: A retrospective cohort study was performed on 102 different canine and 100 different feline patients who were hospitalised for TP from October 2020-January 2022. Patient data were collected, and logistic regression was conducted to determine factors affecting the palpebral reflex and the development of corneal ulcers. RESULTS: Corneal ulcers occurred in 23/102 (22.5%) dogs during hospitalisation and were strongly associated with an incomplete palpebral reflex ipsilaterally during hospitalisation (P < 0.001), hospitalisation ≥3 days (P = 0.004), mechanical ventilation ≥3 days (P = 0.015) or a tick location cranial to C1 (P = 0.003). An incomplete palpebral reflex during hospitalisation was observed in 29/102 (28.4%) dogs and was significantly associated with decreasing patient weight (P = 0.018), increasing days hospitalised (P = 0.001), having a tick found cranial to C1 (P = 0.004), highest recorded GP grade (P = 0.01), highest recorded RP grade (P = 0.005), use of amoxycillin-clavulanic acid during hospitalisation (P = 0.002) and use of piperacillin/tazobactam during hospitalisation (P = 0.003). There was a significant association between the loss of a complete palpebral reflex and mortality during hospitalisation in dogs (OR = 4.5, P = 0.029). Corneal ulcers occurred in 10/100 (10.0%) cats during hospitalisation, and was significantly more likely to occur to an eye if an incomplete palpebral reflex was observed ipsilaterally during hospitalisation (OR = 20.1, P < 0.0001) and with increasing patient age (P = 0.019). The absence of a complete palpebral reflex during hospitalisation was observed in 18/10 (18.0%) cats and was significantly associated with increasing days hospitalised (P = 0.034). There was no significant association between the loss of a complete palpebral reflex and mortality during hospitalisation in cats. CONCLUSIONS: The frequency of corneal ulcers and loss of palpebral reflexes were significant in dogs and cats hospitalised by TP, with many factors contributing to the risk of these developing.

Assessment of autonomic symptom scales in patients with neurodevelopmental diagnoses using electronic health record data.

Background: Sleep disturbances, gastrointestinal problems, and atypical heart rate are commonly observed in patients with autism spectrum disorder (ASD) and may relate to underlying function of the autonomic nervous system (ANS). The overall objective of the current study was to quantitatively characterize features of ANS function using symptom scales and available electronic health record (EHR) data in a clinically and genetically characterized pediatric cohort. Methods: We assessed features of ANS function via chart review of patient records adapted from items drawn from a clinical research questionnaire of autonomic symptoms. This procedure coded for the presence and/or absence of targeted symptoms and was completed in 3 groups of patients, including patients with a clinical neurodevelopmental diagnosis and identified genetic etiology (NPD, n=244), those with an ASD diagnosis with no known genetic cause (ASD, n=159), and age and sex matched controls (MC, n=213). Symptoms were assessed across four main categories: (1) Mood, Behavior, and Emotion; (2) Secretomotor, Sensory Integration; (3) Urinary, Gastrointestinal, and Digestion; and (4) Circulation, Thermoregulation, Circadian function, and Sleep/Wake cycles. Results: Chart review scores indicate an increased rate of autonomic symptoms across all four sections in our NPD group as compared to scores with ASD and/or MC. Additionally, we note several significant relationships between individual differences in autonomic symptoms and quantitative ASD traits. Conclusion: These results highlight EHR review as a potentially useful method for quantifying variance in symptoms adapted from a questionnaire or survey. Further, using this method indicates that autonomic features are more prevalent in children with genetic disorders conferring risk for ASD and other neurodevelopmental diagnoses.

MRI Assessment of Extramural Venous Invasion Before and After Total Neoadjuvant Therapy for Locally Advanced Rectal Cancer and Its Association with Disease-Free and Overall Survival.

BACKGROUND: Extramural venous invasion (EMVI) on baseline MRI is associated with poor prognosis in patients with locally advanced rectal cancer. This study investigated the association of persistent EMVI after total neoadjuvant therapy (TNT) (chemoradiotherapy and systemic chemotherapy) with survival. METHODS: Baseline MRI, post-TNT MRI, and surgical pathology data from 175 patients with locally advanced rectal cancer who underwent TNT and total mesorectal excision between 2010 and 2017 were retrospectively analyzed for evidence of EMVI. Two radiologists assessed EMVI status with disagreement adjudicated by a third. Pathologic EMVI status was assessed per departmental standards. Cox regression models evaluated the associations between EMVI and disease-free and overall survival. RESULTS: EMVI regression on both post-TNT MRI and surgical pathology was associated with disease-free survival (hazard ratio, 0.17; 95% confidence interval (CI), 0.04-0.64) and overall survival (hazard ratio, 0.11; 95% CI, 0.02-0.68). In an exploratory analysis of 35 patients with EMVI on baseline MRI, only six had EMVI on pathology compared with 18 on post-TNT MRI; these findings were not associated (p = 0.2). Longer disease-free survival was seen with regression on both modalities compared with remaining positive. Regression on pathology alone, independent of MRI EMVI status, was associated with similar improvements in survival. CONCLUSIONS: Baseline EMVI is associated with poor prognosis even after TNT. EMVI regression on surgical pathology is common even with persistent EMVI on post-TNT MRI. EMVI regression on surgical pathology is associated with improved DFS, while the utility of post-TNT MRI EMVI persistence for decision-making and prognosis remains unclear.

Pulmonary Hypertension Phenotype Can Be Identified in Heart Failure With Reduced Ejection Fraction Using Echocardiographic Assessment of Pulmonary Artery Pressure With Supportive Use of Pressure Reflection Variables.

BACKGROUND: Pulmonary hypertension (PH) is frequent in patients with heart failure and reduced ejection fraction (HFrEF) with 2 different phenotypes: isolated postcapillary PH (IpcPH) and, with the worst prognosis, combined pre- and postcapillary PH (CpcPH). The aims of the present echocardiography study were to investigate (1) the ability to identify PH phenotype in patients with HFrEF using the newly adopted definition of PH (mean pulmonary artery pressure >20 mm Hg) and (2) the relationship between PH phenotype and right ventricular (RV) function. METHODS: One hundred twenty-four patients with HFrEF consecutively referred for heart transplant or heart failure workup were included with echocardiography and right heart catheterization within 48 hours. We estimated systolic pulmonary artery pressure (sPAPDoppler) and used a method to detect increased pulmonary vascular resistance (>3 Wood units) based on predefined thresholds of 3 pressure reflection (PRefl) variables (the acceleration time in the RV outflow tract [RVOT], the interval between peak RVOT and peak tricuspid regurgitant velocity, and the RV pressure augmentation following peak RVOT velocity). RESULTS: Using receiver operator characteristic analysis in a derivation group (n = 62), we identified sPAPDoppler ≥35 mm Hg as a cutoff that in a test group (n = 62) increased the likelihood of PH 6.6-fold. The presence of sPAPDoppler >40 mm Hg and 2 or 3 positive PRefl variables increased the probability of CpcPH 6- to 8-fold. A 2-step approach with primarily assessment of sPAPDoppler and the supportive use of PRefl variables in patients with mild/moderate PH (sPAPDoppler 41-59 mm Hg) showed 76% observer agreement and a weighted kappa of 0.63. The steady-state (pulmonary vascular resistance) and pulsatile (compliance, elastance) vascular loading are increased in both IpcPH and CpcPH with a comparable degree of RV dysfunction. CONCLUSIONS: The PH phenotype can be identified in HFrEF using standard echocardiographic assessment of pulmonary artery pressure with supportive use of PRefl variables in patients with mild to moderate PH.

Noninvasive Assessment of Left Ventricular Pressure-Volume Relations: Inter- and Intraobserver Variability and Assessment Across Heart Failure Subtypes.

A novel method to derive pressure-volume (PV) loops noninvasively from cardiac magnetic resonance images has recently been developed. The aim of this study was to evaluate inter- and intraobserver variability of hemodynamic parameters obtained from noninvasive PV loops in healthy controls, subclinical diastolic dysfunction (SDD), and patients with heart failure with preserved ejection fraction, mildly reduced ejection fraction, and reduced ejection fraction. We included 75 subjects, of whom 15 were healthy controls, 15 subjects with SDD (defined as fulfilling 1 to 2 echocardiographic criteria for diastolic dysfunction), and 15 patients with preserved ejection fraction, 15 with mildly reduced ejection fraction, and 15 with reduced ejection fraction. PV loops were computed using time-resolved left ventricular volumes from cardiac magnetic resonance images and a brachial blood pressure. Inter- and intraobserver variability and intergroup differences of PV loop-derived hemodynamic parameters were assessed. Bias was low and limits of agreement were narrow for all hemodynamic parameters in the inter- and intraobserver comparisons. Interobserver difference for stroke work was 2 ± 9%, potential energy was 4 ± 11%, and maximal ventricular elastance was -4 ± 7%. Intraobserver for stroke work was -1 ± 7%, potential energy was 3 ± 4%, and maximal ventricular elastance was 1 ± 5%. In conclusion, this study presents a fully noninvasive left ventricular PV loop analysis across healthy controls, subjects with SDD, and patients with heart failure with preserved or impaired systolic function. In conclusion, the method for PV loop computation from clinical-standard manual left ventricular segmentation was rapid and robust, bridging the gap between clinical and research settings.

Assessment of Patient-Reported Outcomes in Patients With Anal Squamous-Cell Cancer Undergoing Combined Modality Therapy.

BACKGROUND: There is limited knowledge on long-term bowel, sexual, and urinary function after combined modality therapy for anal squamous-cell cancer. OBJECTIVE: This study aimed to evaluate long-term changes in patients treated with combined modality. DESIGN: This was a retrospective study of prospectively collected patient-reported outcome surveys. SETTING: This study was conducted at a single institution. PATIENTS: There were 143 patients with stage I to III anal cancer who were treated with chemoradiation and had completed the survey. MAIN OUTCOME MEASURES: This study included patient-reported outcomes reflecting bowel, sexual, and urinary function. RESULTS: Thirty-nine percent of patients had major low anterior resection syndrome at baseline. Major low anterior resection syndrome remained stable (38%; 95% CI, 31%-46%) with no change over time (OR 0.95; 95% CI, 0.74-1.21; p = 0.7). Higher rates of major low anterior resection syndrome were observed for patients who had major low anterior resection syndrome at baseline (OR 20.7; 95% CI 4.70-91.3; p < 0.001) and for females (OR 2.14; 95% CI, 1.01-4.56; p = 0.047). On 5-point scales, we saw a nonsignificant increased level of sexual arousal during sexual activity after therapy for women (ß for 1 year = 0.15; 95% CI, -0.01 to 0.32; p = 0.072) and nonsignificant decreased confidence in getting and keeping an erection after therapy for men (ß for 1 year = -0.33; 95% CI, -0.66 to 0.00; p = 0.053). LIMITATIONS: This was a single-institution study and only patients who answered the questionnaire were included in the study. CONCLUSIONS: A significant proportion of patients have major low anterior resection syndrome at baseline and after successful treatment for anal cancer. Having major low anterior resection syndrome at baseline was the biggest predictor of having major low anterior resection syndrome after treatment. Bowel, sexual, and urinary function did not improve over time up to 2 years after end of treatment. Physicians should counsel their patients before treatment that baseline poor bowel function is a risk factor for posttreatment bowel dysfunction. See Video Abstract at http://links.lww.com/DCR/C29 . EVALUACIN DE LOS RESULTADOS INFORMADOS POR LOS PACIENTES CON CNCER ANAL DE CLULAS ESCAMOSAS QUE SE SOMETEN A UNA TERAPIA DE MODALIDAD COMBINADA: ANTECEDENTES:Existe un conocimiento limitado sobre la función intestinal, sexual y urinaria a largo plazo después de la terapia de modalidad combinada para el cáncer anal de células escamosas.OBJETIVO:Evaluar los cambios a largo plazo en la función intestinal, sexual y urinaria en pacientes tratados con modalidad combinada.DISEÑO:Este fue un estudio retrospectivo de encuestas de resultados informadas por pacientes recolectadas prospectivamente.ESCENARIO:Institución única.PACIENTES:Fueron 143 pacientes con cáncer anal en estadio I-III que fueron tratados con quimiorradiación y completaron la encuesta.PRINCIPALES MEDIDAS DE RESULTADO:Resultados reportados por el paciente que reflejan la función intestinal, sexual, y urinaria.RESULTADOS:Treinta y nueve por ciento de los pacientes tenían puntajes importantes de síndrome de resección anterior bajo al inicio del estudio. Las puntuaciones del síndrome de resección anterior baja mayor permanecieron estables (38 %; IC del 95%: 31 %, 46 %) sin cambios con el tiempo (OR 0,95, IC del 95%: 0,74, 1,21, p = 0,7). Se observaron tasas más altas de puntuaciones del síndrome de resección anterior baja mayor para los pacientes que tenían puntuaciones del síndrome de resección anterior baja mayor desde el inicio (OR 20,7; IC del 95%: 4,70; 91,3, p < 0,001) y para las mujeres (OR 2,14; IC del 95%: 1,01, 4,56; p = 0,047). En escalas de 5 puntos, observamos un aumento no significativo del nivel de excitación sexual durante la actividad sexual después de la terapia para las mujeres (ß durante 1 año = 0,15; IC del 95%: -0,01, 0,32; p = 0,072) y una disminución no significativa de la confianza en lograr y mantener una erección después de la terapia para hombres (ß para 1 año = -0,33; IC del 95%: -0,66, 0,00; p = 0,053).LIMITACIONES:Este es un estudio de una sola institución. Solo se incluyeron en el estudio los pacientes que contestaron el cuestionario.CONCLUSIONES:Una proporción significativa de pacientes tienen puntajes de síndrome de resección anterior muy bajos al inicio del estudio y después de un tratamiento exitoso para el cáncer anal. Tener puntajes de síndrome de resección anterior bajos importantes al inicio del estudio fue el predictor más importante de tener puntajes de síndrome de resección anterior bajos importantes después del tratamiento. La función intestinal, sexual y urinaria no mejoró con el tiempo hasta 2 años después de finalizar el tratamiento. Los médicos deben aconsejar a sus pacientes antes del tratamiento que la mala función intestinal inicial es un factor de riesgo para la disfunción intestinal posterior al tratamiento.

Bioactive adrenomedullin for assessment of venous congestion in heart failure.

AIMS: Bioactive adrenomedullin (bio-ADM) is a vascular-derived peptide hormone that has emerged as a promising biomarker for assessment of congestion in decompensated heart failure (HF). We aimed to evaluate diagnostic and prognostic performance of bio-ADM for HF in comparison to amino-terminal pro-B-type natriuretic peptide (NT-proBNP), with decision thresholds derived from invasive haemodynamic and population-based studies. METHODS AND RESULTS: Normal reference ranges for bio-ADM were derived from a community-based cohort (n = 5060). Correlations with haemodynamic data were explored in a cohort of HF patients undergoing right heart catheterization (n = 346). Mortality and decision cutoffs for bio-ADM was explored in a cohort of patients presenting in the ER with acute dyspnoea (n = 1534), including patients with decompensated HF (n = 570). The normal reference range was 8-39 pg/mL. The area under the receiver operating characteristic curve (AUROC) for discrimination of elevated mean right atrial pressure (mRAP) and pulmonary arterial wedge pressure (PAWP) was 0.74 (95% CI = 0.67-0.79) and 0.70 (95% CI = 0.64-0.75), respectively, with optimal bio-ADM decision cutoff of 39 pg/mL, concordant with cubic spline analyses. NT-proBNP discriminated PAWP slightly better than mRAP (AUROC 0.73 [95% CI = 0.68-0.79] and 0.68 [95% CI = 0.61-0.75]). Bio-ADM correlated with (mRAP, r = 0.55) while NT-proBNP correlated with PAWP. Finally, a bio-ADM decision cutoff of 39 pg/mL associated with 30 and 90 day mortality and conferred a two-fold increased odds of HF diagnosis, independently from NT-proBNP. CONCLUSIONS: Bio-ADM tracks with mRAP and associates with measures of systemic congestion and with mortality in decompensated HF independently from NT-proBNP. Our findings support utility of bio-ADM as a biomarker of systemic venous congestion in HF and nominate a decision threshold.

Evaluating the Validity of the Clavien-Dindo Classification in Colectomy Studies: A 90-Day Cost of Care Analysis.

BACKGROUND: The Clavien-Dindo classification is widely used to report postoperative morbidity but may underestimate the severity of colectomy complications. OBJECTIVE: The purpose of this study was to assess how well the Clavien-Dindo classification represents the severity of all grades of complications after colectomy using cost of care modeling. DESIGN: This was a retrospective cohort study. SETTINGS: The study was conducted at a comprehensive cancer center. PATIENTS: Consecutive patients (N = 1807) undergoing elective colon or rectal resections without a stoma performed at Memorial Sloan Kettering Cancer Center between 2009 and 2014 who were followed up for ≥90 days, were not transferred to other hospitals, and did not receive intraperitoneal chemotherapy were included in the study. MAIN OUTCOME MEASURES: Complication severity was measured by the highest-grade complication per patient and attributable outpatient and inpatient costs. Associations were evaluated between patient complication grade and cost during 3 time periods: the 90 days after surgery, index admission, and postdischarge (<90 d). RESULTS: Of the 1807 patients (median age = 62 y), 779 (43%) had a complication; 80% of these patients had only grade 1 or 2 complications. Increasing patient complication grade correlated with 90-day cost, driven by inpatient cost differences (p < 0.001). For grade 1 and 2 patients, most costs were incurred after discharge and were the same between these grade categories. Among patients with a single complication (52%), there was no difference in index hospitalization, postdischarge, or total 90-day costs between grade 1 and 2 categories. LIMITATIONS: The study was limited by its retrospective design and generalizability. CONCLUSIONS: The Clavien-Dindo classification correlates well with 90-day costs, driven largely by inpatient resource use. Clavien-Dindo does not discriminate well among patients with low-grade complications in terms of their substantial postdischarge costs. These patients represent 80% of patients with a complication after colectomy. Examining the long-term burden associated with complications can help refine the Clavien-Dindo classification for use in colectomy studies. See Video Abstract at http://links.lww.com/DCR/B521.

Se evaluó la asociación entre el grado de complicación del paciente y el costo durante 3 períodos de tiempo: posterior a la cirugía (hasta 90 días), a su ingreso y posterior al egreso (hasta 90 días).RESULTADOS:De los 1807 pacientes (mediana de edad de 62 años), 779 (43%) tuvieron una complicación; El 80% de estos pacientes tuvieron solo complicaciones de grado 1 o 2. El aumento del grado de complicación del paciente se correlacionó con el costo a 90 días, impulsado por las diferencias en el costo de los pacientes hospitalizados (p <0,001). Para los pacientes de grado 1 y 2, la mayoría de los costos se incurrieron después del alta y fueron los mismos entre ambas categorías. Entre los pacientes con una sola complicación (52%), no hubo diferencia en el índice de hospitalización, posterior al alta o en el costo total de 90 días entre las categorías de grado 1 y 2.LIMITACIONES:Diseño retrospectivo, generalizabilidad.CONCLUSIONES:La clasificación de Clavien-Dindo se correlaciona bien con los costos a 90 días, impulsados en gran parte por la utilización de recursos de pacientes hospitalizados. Clavien-Dindo no discrimina entre los pacientes con complicaciones de bajo grado en términos de sus costos sustanciales posterior al alta. Estos pacientes representan el 80% de los pacientes aquellos con una complicación tras la colectomía. Examinar la carga a largo plazo asociada a las complicaciones puede ayudar a mejorar la clasificación de Clavien-Dindo para su uso en estudios de colectomía.

Development and feasibility of a Configurable Assessment Messaging Platform for Interventions (CAMPI).

INTRODUCTION: Short message service (SMS) is a widely accepted telecommunications approach used to support health informatics, including behavioral interventions, data collection, and patient-provider communication. However, SMS delivery platforms are not standardized and platforms are typically commercial "off-the-shelf" or developed "in-house." As a consequence of platform variability, implementing SMS-based interventions may be challenging for both providers and patients. Off-the-shelf SMS delivery platforms may require minimal development or technical resources from providers, but users are often limited in their functionality. Conversely, platforms that are developed in-house are often specified for individual projects, requiring specialized development and technical expertise. Patients are on the receiving end of programming and technical specification challenges; message delays or lagged data affect quality of SMS communications. To date, little work has been done to develop a generalizable SMS platform that can be scaled across health initiatives. OBJECTIVE: We propose the Configurable Assessment Messaging Platform for Interventions (CAMPI) to mitigate challenges associated with SMS intervention implementation (e.g., programming, data collection, message delivery). METHOD: CAMPI aims to optimize health data captured from a multitude of sources and enhance patient-provider communication through a technology that is simple and familiar to patients. Using representative examples from three behavioral intervention case studies implemented among diverse populations (pregnant women, young sexual minority men, and parents with young children), we describe CAMPI capabilities and feasibility. CONCLUSION: As a generalizable SMS platform, CAMPI can be scaled to meet the priorities of various health initiatives, while reducing unnecessary resource utilization and burden on providers and patients.

Climbing the grants ladder: Funding opportunities for surgeons.

Surgeon-scientists provide critical perspectives to academic medicine, both as lead scientists and as collaborators. Successfully applying for and obtaining funding is critical to sustain a research program; however, significant challenges exist. It is imperative to be aware of and consider all funding sources available to surgeons during the evolution of one's career. Additionally, a deep understanding of intramural and extramural nonfinancial resources, such as mentorship relationships, grant writing, and career development courses, and research infrastructure are required. In this article, we present a set of recommendations and guidelines for surgeon-scientists to leverage funding resources with active planning longitudinally during their careers to sustain their research programs and provide their unique perspectives on surgical disease to the scientific community.

Implementing Implementation Research: Teaching Implementation Research to HIV Researchers.

PURPOSE OF REVIEW: Given the growth in HIV-related implementation research, there is a need to expand the workforce and rigor through implementation science (IS) training and mentorship. Our objective is to review IS training opportunities for HIV-focused researchers and describe the approach and lessons learned from a recent HIV-related implementation research training initiative. RECENT FINDINGS: IS training opportunities range from degree programs to short- and longer-term professional development institutes and community-focused institutional trainings. Until recently, there have not been extensive dedicated opportunities for implementation research training for HIV-focused investigators. To meet this gap, an inter-Center for AIDS Research IS Fellowship for early-stage investigators was launched in 2019, building on lessons learned from dissemination and implementation training programs. Key components of the HIV-focused IS fellowship include didactic training, mentorship, grant-writing, and development of HIV-IS collaborative networks. Fellows to-date were two-thirds junior faculty and one-third post-doctoral fellows, the majority (69%) with prior public health training. Perceived value of the program was high, with a median rating of 9 [IQR 8-9] on a 10-point scale. Overall, 22/27 (81%) Fellows from the first cohort submitted IS-related grants within 12 months of Fellowship completion, and by 1 year 13 grants had been funded among 10 investigators, 37% overall among Fellows. Mentors identified framing of IS questions as the top-ranked training priority for HIV-investigators. Increasing knowledge of the utility of IS may support more grants focused on optimal implementation of HIV treatment and prevention strategies. Experiences from mentors and trainees engaged in an IS-focused fellowship for HIV investigators demonstrate the demand and value of a dedicated training program and reinforce the importance of mentorship.

Development and evaluation of a novel pre-operative surgery school and behavioural change intervention for patients undergoing elective major surgery: Fit-4-Surgery School.

Group pre-operative education has usually been limited to conditioning expectations and providing education. Prehabilitation has highlighted modifiable lifestyle factors that are amenable to change and may improve clinical outcomes. We instituted a pre-operative 'Fit-4-Surgery School' for patients scheduled for major surgery, to educate and promote healthy behaviour. We evaluated patients' views having attended the school, and after surgery we asked how it had changed their behaviour with a lifestyle questionnaire. The school was launched in May 2016 and was attended by 586/1017 (58%) of invited patients. Patients who did not attend: lived further away, median (IQR [range]) 8 (4-19 [0-123]) miles vs. 5 (3-14 [0-172]) miles, p < 0.001; and were more deprived, Index of Multiple Deprivation Rank decile median (IQR [range]), 6 (4-8 [1-10]) vs. 7 (4-9 [1-10]), p = 0.04. Of the 492/586 (84%) participants who completed an evaluation questionnaire, 462 (94%) would recommend the school to a friend having surgery and 296 (60%) planned lifestyle changes. After surgery, 232/586 (40%) completed a behavioural change questionnaire, 106 (46%) of whom reported changing at least one lifestyle factor, most commonly by increasing exercise. The pre-operative school was acceptable to patients.

OPTN/SRTR 2019 Annual Data Report: Heart.

The new adult heart allocation policy was approved in 2016 and implemented in October 2018. This year's Annual Data Report provides early insight into the effects of this policy. In 2019, new listings continued to increase, with 4086 new candidates. Also in 2019, 3597 heart transplants were performed, an increase of 157 (4.6%) from 2018; 509 transplants occurred in children and 3088 in adults. Short- and long-term posttransplant mortality rates improved. Overall, Mortality rates for adult recipients were 6.4% at 6 months and 7.9% at 1 year for transplants in 2018, 14.4% at 3 years for transplants in 2016, and 20.1% at 5 years for transplants in 2014. Mortality rates for pediatric recipients were 6.3% at 6 months and 8.2% at 1 year for transplants in 2018, 10.3% at 3 years for transplants in 2016, and 17.8% at 5 years for transplants in 2014.

Perceptions and Motivations for Uterus Transplant in Transgender Women.

Importance: Uterus transplant has been demonstrated to be a viable fertility-restoring treatment for women categorized as female at birth with absolute uterine factor infertility. Recent advancements, as well as considerations of fairness and equality in reproductive care, have now led to the possibility of uterus transplant being undertaken in transgender women. Objective: To investigate the reproductive aspirations of transgender women and their perceptions of uterus transplant. Design, Setting, and Participants: This cross-sectional survey study used a 27-item electronic questionnaire to investigate the reproductive aspirations of 182 transgender women older than 16 years, including their perceptions of and motivations for uterus transplant, between May 1 and November 1, 2019. Main Outcomes and Measures: Perceptions of and motivations for uterus transplant, including perceived significance of the ability to gestate, menstruate, and have a physiologically functioning vagina. Results: A total of 182 transgender women completed the questionnaire; most women (109 [60%]) were aged 20 to 29 years. Most did not have children prior to transitioning (167 [92%]) and expressed a desire to have children in the future (171 [94%]). In addition, most respondents agreed or strongly agreed that the ability to gestate and give birth to children (171 [94%]) and menstruate (161 [88%]) would enhance perceptions of their femininity. Similarly, high proportions strongly agreed or agreed that having a transplanted, functioning vagina would improve their sexual experience (163 [90%]), improve their quality of life (163 [90%]), and help them to feel like more of a woman (168 [92%]). Nearly all respondents (180 [99%]) believed that uterus transplant would lead to greater happiness in transgender women. More than three-quarters of the respondents (140 [77%]) strongly agreed or agreed that they would be more inclined to cryopreserve sperm if uterus transplant became a realistic option. Conclusions and Relevance: This study provides insights into the reproductive aspirations of transgender women and reports on their multifaceted motivation to undergo uterus transplant. The survey responses suggest that transgender women would choose to have female physiologic experiences, such as menstruation and gestation, as well as potentially having a physiologically functioning transplanted vagina. If proven feasible and safe in this setting, uterus transplant may facilitate the achievement of reproductive aspirations, improve quality of life, and further alleviate dysphoric symptoms in transgender women.

Quantitative assessment of tumor-infiltrating lymphocytes in mismatch repair proficient colon cancer.

Tumor infiltrating lymphocytes (TIL), which represent host adaptive response to the tumor, were first identified at scanning magnification to select areas with the highest counts on hematoxylin and eosin slides, quantitated per high-power field (HPF), and analyzed for association with recurrence-free survival (RFS) in 848 patients. Highest TIL in a single HPF was analyzed as a continuous and categorical variable, and optimal cutoff analysis was performed to predict RFS. Highest TIL count in a single HPF ranged from 0 to 45, and the optimal cutoff for TIL high vs TIL low was determined to be ≥ 3 vs < 3 with a concordance probability estimate of 0.74. In the entire cohort, 5-year RFS was 90.2% (95% CI = 83.7-94.2) in TIL high compared to 78.9% (95% CI = 74.1-82.9) in TIL low (log rank P < .0001). TIL remained significant in the mismatch repair-proficient (pMMR) cohort where 5-year RFS was 94.6% (95% CI = 88.3-97.5) in TIL high compared to 77.9% (95% CI = 69.2-84.4) in TIL low (P = .008). On multivariable analysis, TIL and AJCC Stage were independently associated with RFS in the pMMR cohort. Qualitatively in the pMMR cohort, RFS in Stage II TIL high patients was similar to that in Stage I patients and RFS in Stage III TIL high was similar to that in Stage II TIL low patients. Assessment of TIL in a single HPF using standard H&E slides provides important prognostic information independent of MMR status and AJCC stage.

Does Intentional Support of Degree Programs in General Surgery Residency Affect Research Productivity or Pursuit of Academic Surgery? A Multi-Institutional Study.

OBJECTIVE: To determine whether pursuit of an advanced degree during dedicated research time (DRT) in a general surgery residency training program impacts a resident's research productivity. DESIGN: A retrospective, multi-institutional cohort study. SETTING: General surgery residency programs that were approved to graduate more than 5 categorical residents per year and that offered at least 1 year of DRT were contacted for participation in the study. A total of 10 general surgery residency programs agreed to participate in the study. PARTICIPANTS: Residents who started their residency between 2000 and 2012 and spent at least one full year in DRT (n = 511) were included. Those who completed an advanced degree were compared on the following parameters to those who did not complete one: total number of papers, first-author papers, the Journal Citation Reports impact factors of publication (2018, or most recent), and first position after residency or fellowship training. RESULTS: During DRT, 87 (17%) residents obtained an advanced degree. The most common degree obtained was a Master of Public Health (MPH, n = 42 (48.8%)). Residents who did not obtain an advanced degree during DRT published fewer papers (median 8, [interquartile range 4-12]) than those who obtained a degree (9, [6-17]) (p = 0.002). They also published fewer first author papers (3, [2-6]) vs (5, [2-9]) (p = 0.002) than those who obtained a degree. Resident impact factor (RIF) was calculated using Journal Citation Reports impact factor and author position. Those who did not earn an advanced degree had a lower RIF (adjusted RIF, 84 ± 4 vs 134 ± 5, p < 0.001) compared to those who did. There was no association between obtaining a degree and pursuit of academic surgery (p = 0.13) CONCLUSIONS: Pursuit of an advanced degree during DRT is associated with increased research productivity but is not associated with pursuit of an academic career.

Neighborhood socioeconomic status and aortic stenosis: A Swedish study based on nationwide registries and an echocardiographic screening cohort.

BACKGROUND: Aortic stenosis (AS) is the most common valvular heart disease in developed countries, confers high mortality in advanced cases, but can effectively be reversed using endovascular or open-heart surgery. We evaluated the association between AS and neighborhood socioeconomic status (NSES). METHODS: We used Swedish population-based nationwide registers and an echocardiography screening cohort during the study period 1997-2014. NSES was determined by an established neighborhood deprivation index composed of education, income, unemployment, and receipt of social welfare. Multilevel adjusted logistic regression models determined the association between NSES and incident AS (according to ICD-10 diagnostic codes). RESULTS: The study population of men and women (n=6,641,905) was divided into individuals living in high (n = 1,608,815 [24%]), moderate (n = 3,857,367 [58%]) and low (n = 1,175,723 [18%]) SES neighborhoods. There were 63,227 AS cases in total. Low NSES (versus high) was associated with a slightly increased risk of AS (OR 1.06 [95% CI 1.03-1.08]) in the nationwide study population. In the echocardiography screening cohort (n = 1586), the association between low NSES and AS was markedly stronger (OR: 2.73 [1.05-7.12]). There were more previously undiagnosed AS cases in low compared to high SES neighborhoods (3.1% versus 1.0%). CONCLUSIONS: In this nationwide Swedish register study, low NSES was associated with a slightly increased risk of incident AS. However, the association was markedly stronger in the echocardiography screening cohort, which revealed an almost three-fold increase of AS among individuals living in low SES neighborhoods, possibly indicating an underdiagnosis of AS among these individuals.

Accuracy of subjective vesicoureteral reflux timing assessment: supporting new voiding cystourethrogram guidelines.

BACKGROUND: Bladder volume at the onset of vesicoureteral reflux (VUR) is an important prognostic indicator of spontaneous resolution and the risk of pyelonephritis. OBJECTIVE: We aim to determine whether pediatric urologists and pediatric radiologists can accurately estimate the timing of reflux by examining voiding cystourethrogram (VCUG) images without prior knowledge of the instilled contrast volume. MATERIALS AND METHODS: Total bladder volume and the volume at the time of reflux were collected from VCUG reports to determine the volume at the onset of VUR. Thirty-nine patients were sorted into three groups: early-/mid-filling reflux, late-filling and voiding only. Thirty-nine images were shown to three pediatric urologists and two pediatric radiologists in a blinded fashion and they were then asked to estimate VUR timing based on the above categories. A weighted kappa statistic was calculated to assess rater agreement with the gold standard volume-based report of VUR timing. RESULTS: The mean patient age at VCUG was 3.1±2.9 months, the median VUR was grade 3, and 20 patients were female. Overall agreement among all five raters was moderate (k=0.43, 95% confidence interval [CI] 0.36-0.50). Individual agreement between rater and gold standard was slight to moderate with kappa values ranging from 0.13 to 0.43. CONCLUSION: Pediatric radiologists and urologists are unable to accurately and reliably characterize VUR timing on fluoroscopic VCUG. These findings support the recently published American Academy of Pediatrics protocol recommending the routine recording of bladder volume at the onset of VUR as a standard component of all VCUGs to assist in a more accurate assessment of the likelihood of resolution and risk of recurrent urinary tract infections.

OPTN/SRTR 2018 Annual Data Report: Intestine.

Despite medical and surgical advances in treatment of intestinal failure, intestine transplant still plays an important role. However, the number of new patients added to the intestine transplant waiting list has decreased over the past decade, reaching a low of 135 in 2018. The number of intestine donors also decreased, reaching a low of 106 in 2018, and the number of intestine transplants performed declined to its lowest level, 104, of which 59% were intestine-liver transplants. Graft failure has plateaued over the past decade. Patient survival for transplants in 2011-2013 varied by age and transplant type. Patient survival was lowest for adult intestine-liver recipients (1-and 5-year survival 66.7% and 49.1%, respectively) and highest for pediatric intestine recipients (1-and 5-year survival 89.1% and 76.4%, respectively).
