RESUMO

PURPOSE: To objectively evaluate the subjective symptoms and characteristics of chronic orbital pain as well as to quantify sensitization of peripheral trigeminal nerves. METHODS: In this prospective cohort study, patients who previously showed a response to peripheral trigeminal nerve blocks for unilateral, idiopathic chronic orbital pain and healthy subjects completed validated questionnaires assessing headaches, neuropathic signs and symptoms, photophobia, and pain qualities. Corneal sensitivity was measured in both eyes for all subjects with a Cochet-Bonnet aesthesiometer. For pain patients, the full assessment protocol was repeated 2-4 weeks after the study injection, and corneal sensitivity was also measured 30 minutes postinjection. Outcomes assessed were headache, neuropathic pain, and photophobia scores; pain qualities; and corneal sensitivity. RESULTS: Six female chronic orbital pain patients (mean age 48.2 years) and 11 female controls (mean age 47.5) were included. The mean headache, neuropathic pain, and photophobia questionnaire scores were significantly higher for pain patients than for controls (p < 0.001). On sensory testing, 5 pain patients (83.3%) endorsed allodynia, and all 6 (100%) had hyperalgesia in the ipsilateral frontal nerve dermatome. No controls had allodynia or hyperalgesia. Corneal sensitivity was similar between eyes in pain patients and between groups. Questionnaire scores and corneal sensitivity did not change significantly after the injection. CONCLUSIONS: Chronic orbital pain patients have a measurable reduction in quality of life due to headaches and photophobia. The supraorbital and supratrochlear nerves are sensitized, resulting in cutaneous hypersensitivity in the corresponding dermatome, but corneal nerves have normal sensitivity.

RESUMO

Redox regulation is a posttranslational modification based on the redox reaction of protein thiols. A small ubiquitous protein thioredoxin (Trx) plays a central role in redox regulation, but a unique redox-regulatory factor called NADPH-Trx reductase C (NTRC) is also found in plant chloroplasts and some cyanobacteria. Several important functions of NTRC have been suggested, but the mechanism for controlling NTRC activity remains undetermined. Cystathionine-ß-synthase X (CBSX) proteins have been previously shown to interact with NTRC physically. Based on these observations, this study biochemically investigated the functional interaction between CBSX proteins and NTRC from Arabidopsis thaliana in vitro. Consequently, we concluded that CBSX proteins act as negative regulators of NTRC in the presence of AMP.

RESUMO

Digital papillary adenocarcinoma (DPA) is a rare neoplasm that can exhibit local recurrence and distant metastasis. We present a series of eight cases of DPA showing two distinct clinical presentations, morphologies, immunophenotypes, and molecular features. Four cases were characterized by painless, slow-growing nodules located on the digits. The lesions were small, well-defined, and confined in the dermis. Histopathologically, these tumors were composed of glandular structures lined by cuboidal epithelium with luminal papillary infoldings. Only rare mitotic figures and minimal squamoid differentiation were present, and cellular necrosis was absent. All four cases were positive for the BRAF V600E immunohistochemistry but negative for p16, low-risk and high-risk HPV in situ hybridization (ISH). In contrast, the remaining four cases were characterized by painful, rapidly growing masses on the digits. These four lesions were located in the deep dermis and consisted of a solid, tightly packed papillary architecture lined by atypical epithelioid cells with inconspicuous nucleoli. Cellular necrosis, numerous mitotic figures, and prominent squamoid differentiation were seen. All cases were negative for the BRAF V600E IHC. However, they showed strong, patchy to diffuse reactivity for p16 and were positive for low-risk HPV ISH and negative for high-risk HPV ISH. Our findings suggest that the current classification of DPA encompasses tumors that show two discrete pathogenic pathways - BRAF mutation or low-risk HPV infection. DPAs with low-risk HPV infection exhibit aggressive clinical features, high-grade morphology, marked squamoid differentiation, and wild-type BRAF. DPAs with BRAF V600E have less aggressive clinical features, low-grade morphologic findings, mild to absent squamoid differentiation, and negative HPV infection.

RESUMO

OBJECTIVE: The diagnostic yield for congenital heart defects (CHD) with routine genetic testing is around 10%-20% when considering pathogenic CNVs or aneuploidies as positive findings. This is a pilot study to investigate the utility of genome sequencing (GS) for prenatal diagnosis of CHD. METHODS: Genome sequencing (GS, 30X) was performed on 13 trios with CHD for which karyotyping and/or chromosomal microarray results were non-diagnostic. RESULTS: Trio GS provided a diagnosis for 4/13 (30.8%) fetuses with complex CHDs and other structural anomalies. Findings included pathogenic or likely pathogenic variants in DNAH5, COL4A1, PTPN11, and KRAS. Of the nine cases without a genetic etiology by GS, we had outcome follow-up data on eight. For five of them (60%), the parents chose to keep the pregnancy. A balanced translocation [46,XX,t(14; 22)(q32.33; q13.31)mat] was detected in a trio with biallelic DNAH5 mutations, which together explained the recurrent fetal situs inversus and dextrocardia that was presumably due to de novo Phelan-McDermid syndrome. A secondary finding of a BRCA2 variant and carrier status of HBB, USH2A, HBA1/HBA2 were detected in the cohort. CONCLUSIONS: GS expands the diagnostic scope of mutation types over conventional testing, revealing the genetic etiology for fetal heart anomalies. Patients without a known genetic abnormality indicated by GS likely opted to keep pregnancy especially if the heart defect could be surgically repaired. We provide evidence to support the application of GS for fetuses with CHD.

RESUMO

PURPOSE: To characterize chronic orbital pain in patients who benefitted from peripheral trigeminal nerve blocks and to explore the relationship between pain etiologies and phenotypes, injection attributes, and positive response to treatment. METHODS: In this single-center retrospective descriptive study, patients who underwent peripheral trigeminal nerve blocks for chronic orbital pain from November 2016 to May 2021 were selected. Data reviewed included inciting factors, neuropathic symptoms of orbital pain, injection composition (anesthetic alone versus anesthetic + dexamethasone), and corneal epitheliopathy grades. Primary outcomes assessed were response to injection, duration of injection effectiveness, and overall treatment efficacy. Associations between subgroups of chronic orbital pain, injection attributes, and treatment outcomes were examined. RESULTS: Nineteen patients who underwent a total of 94 peripheral trigeminal nerve blocks for chronic orbital pain were included. During a mean follow-up period of 2.4 years after initial injection (range 7 days-4.6 years), 16 (84.2%) patients achieved either partial or complete improvement. Ocular versus nonocular origin of orbital pain or the presence of neuropathic sensory characteristics was not associated with a treatment outcome. Injections containing dexamethasone had a lower positive efficacy (relative risk, 0.88; 95% CI, 0.81-0.97) and no statistically significant association with prolonged effect. Twenty-nine (50.9%) of the 57 injections for which effect duration was recorded produced a response lasting greater than 6 weeks. CONCLUSIONS: Modulation of trigeminal afferent nerve activity with peripheral trigeminal nerve blocks containing anesthetic with or without dexamethasone may be a promising treatment strategy for chronic orbital pain of diverse etiologies and phenotypes.

RESUMO

PURPOSE: To evaluate extraocular muscle response to teprotumumab using orbital echography in thyroid eye disease. METHODS: This retrospective study included adult thyroid eye disease patients with pre- and post-teprotumumab orbital echography. Data collected included: age, Hertel measurements, clinical activity score, Gorman diplopia scores, ocular motility, and recti muscle diameters measured by echography. The patient's more proptotic eye before treatment initiation was designated as the study orbit. Ocular motility was assessed by totaling the ductions in all 4 cardinal directions. Orbital echography was obtained pre- and post-treatment to assess response of extraocular muscle diameters. RESULTS: Six patients with a mean age of 67 years were included. There was a mean improvement in proptosis of 4.3 mm in the study eye with 11/12 orbits showing improvement in globe position ( p < 0.05). All patients had a decrease in clinical activity score with a mean reduction of 2.5. Four patients had an improvement in Gorman diplopia score. Ocular motility in the study orbits improved by a total mean of 26.9° ( p < 0.05). Mean total extraocular muscle diameter was reduced from 27.4 to 23.4 mm ( p < 0.001). On average, superior recti were largest pre- and post-treatment, followed by inferior, medial, then lateral recti. However, inferior recti showed the greatest reduction of 23% ( p < 0.02). CONCLUSIONS: Orbital echography demonstrated extraocular muscle reduction in all patients after teprotumumab, correlating with improved clinical activity score, ocular motility, and proptosis. Orbital echography is a safe and cost-effective imaging alternative to monitor therapeutic response to teprotumumab.

RESUMO

BACKGROUND: Lid-sharing approaches are often advocated for repair of large full thickness lower eyelid defects, however result in temporary visual obstruction and the need for a second-stage procedure. The authors describe and report outcomes using a one-stage technique utilizing a free tarsoconjunctival graft (TCG) and musculocutaneous transposition flap (MCT) to repair defects up to 90% of the lower eyelid. METHODS: A retrospective chart review on patients that had undergone full thickness lower eyelid reconstruction using a TCG and MCT between the dates of 1/1/2015 to 3/1/2020 was performed. Demographic and clinical information including indication for repair, size of defect, post-operative complications, and outcomes were recorded and analyzed. RESULTS: Six cases of lower eyelid reconstruction using this technique were identified. Fifty percent were male, average age was 61.3 years (range 36-91, SD = 18.9), and follow up was 36.7 weeks (range 3-129, SD = 48.1). All defects were due to malignancy (4/6 for basal cell carcinoma, 1/6 each for sebaceous cell carcinoma and merkel cell carcinoma). Average horizontal defect size was 80% of lower eyelid width (range 57%-90%, SD = 12.3), while average vertical defect size was 8 mm (range 5-10 mm, SD = 1.7). There were no instances of post-operative infection, lid malposition, or dehiscence. A pyogenic granuloma was noted in one case and was managed with excision. CONCLUSION: A single-stage procedure using a TCG and MCT can be used to repair laterally based full-thickness lower eyelid defects up to 90% with satisfactory outcomes and few complications.

RESUMO

OBJECTIVE: To evaluate the utility of expanded non-invasive prenatal screening (NIPS), compared with chromosomal microarray analysis (CMA), for the detection of chromosomal abnormalities in high-risk pregnancies. METHODS: This was a multicenter retrospective study of singleton pregnancies at high risk for chromosomal abnormality. Patients who underwent expanded NIPS and CMA sequentially during pregnancy from 2015 to 2019 were included in the analysis. Pregnancies with a positive result for sex chromosome aneuploidy were excluded as the full details could not be retrieved. The utility of expanded NIPS and CMA for detection of chromosomal abnormalities in this cohort was compared by assessing the concordance between the results. RESULTS: Of the 774 included high-risk pregnancies, 550 (71.1%) had a positive NIPS result, while a positive CMA result was detected in 308 (39.8%) cases. The rate of full or partial concordance between NIPS and CMA was 82.2%, 59.6% and 25.0% for trisomies 21, 18 and 13, respectively. For rare aneuploidies and segmental imbalances, NIPS and CMA results were fully or partially concordant in 7.5% and 33.3% of cases, respectively. Copy-number variants < 5 Mb were detected more often by CMA, with an incidence of 7.9% (61/774) compared with 3.1% (24/774) by NIPS. A genetic aberration was detected by CMA in 1 in 17 (5.8%) high-risk pregnancies that had a negative or non-reportable NIPS result. CONCLUSION: CMA allows for comprehensive detection of genome-wide chromosomal abnormalities in high-risk pregnancies. CMA should be offered instead of expanded NIPS for high-risk pregnancies.

RESUMO

CAVIAR is a multicentre prospective stepped observational study encompassing 160 patients undergoing vascular intervention. The aim was to identify whether it was feasible to establish a preoperative anaemia pathway and, if so, the efficacy of intravenous iron for treatment of preoperative anaemia. Large barriers prevented implementation of an intravenous iron pathway, with only ten patients receiving intravenous iron and a small increase in haemoglobin level (mean 5·7 (95 per cent c.i. 4·5 to 6·9) g/l). Preoperative anaemia was associated with a longer hospital stay and greater transfusion requirement. Anaemia common and dedicated pathway difficult to instigate.

RESUMO

BACKGROUND: Discharge to nonhome settings after colorectal resection may increase risk of hospital readmission. OBJECTIVE: The purpose of this study was to determine the impact of various discharge dispositions on 30-day readmission after adjusting for confounding demographic and clinical factors. DESIGN: This was a retrospective cohort study. SETTINGS: Data were obtained from the University HealthSystem Consortium (2011-2015). PATIENTS: Adults who underwent elective colorectal resection were included. MAIN OUTCOME MEASURES: Thirty-day hospital readmission risk was measured. RESULTS: The mean age of the study population (n = 97,455) was 58 years; half were men and 78% were white. Seventy percent were discharged home routinely (home without service), 24% to home with organized health services, 5% to skilled nursing facility, 1% to rehabilitation facility, and <1% to long-term care hospital. Overall rate of readmission was 12%; 9% from home without service, 16% from home with organized home health services, 19% from skilled nursing facility, 34% from rehabilitation facility, and 22% from long-term care hospital (p < 0.001). Patients with an intensive care unit stay, more postoperative complications, and longer hospitalization stay were more likely to be discharged to home with organized home health services or to a facility (p < 0.001). Discharge to home with organized home health services, skilled nursing facility, or rehabilitation facility increased multivariable-adjusted readmission risk by 30% (OR = 1.3 (95% CI, 1.3-1.6)), 60% (OR = 1.6 (95% CI, 1.5-1.8)), or 200% (OR = 3.0 (95% CI, 2.5-3.6)). Discharge to long-term care hospital was not associated with higher adjusted readmission risk (OR = 1.2 (95% CI, 0.9-1.6)), despite this group having the highest comorbidity and postoperative complications. Among patients readmitted within 30 days, median time to readmission was significantly different among home without service (n = 7), home with organized home health services (n = 8), skilled nursing facility (n = 8), rehabilitation facility (n = 9), and long-term care hospital (n = 12; p < 0.001). LIMITATIONS: This study was limited by its retrospective nature. CONCLUSIONS: Discharge to home with organized home health services, skilled nursing facility, or rehabilitation facility, but not long-term care hospital, is associated with increased adjusted risk of readmission compared with routine home discharge. Potential targets to decrease readmission include improving transition of care at discharge, improving quality of care after discharge, and improving facility resources.

NO TODAS LAS CONFIGURACIONES DE ALTA SON IGUALES: RIESGOS DE READMISIÓN A 30 DÍAS DESPUÉS DE CIRUGÍA COLORRECTAL ELECTIVA: El alta hospitalaria hacia el domicilio luego de una resección colorrectal puede aumentar el riesgo de readmisión.Determinar el impacto de varias configuraciones diferentes de alta en la readmisión a 30 días luego de ajustar factores demográficos y clínicos.Estudio de cohortes retrospectivo.Los datos se obtuvieron del Consorcio del Sistema de Salud Universitaria (2011-2015).Todos aquellos adultos que se sometieron a una resección colorrectal electiva.Los riesgos de readmisión hospitalaria a 30 días.La edad media de la población estudiada (n = 97,455) fué de 58 años; la mitad eran hombres y un 78% eran blancos. El 70% fueron dados de alta de manera rutinaria (a domicilio sin servicios complementarios), 24% alta a domicilio con servicios de salud organizados, 5% alta hacia un centro con cuidados de enfermería especializada, 1% alta hacia un centro de rehabilitación y <1% alta hacia un hospital con atención a largo plazo. La tasa global de readmisión fué del 12%; nueve por ciento desde domicilios sin servicios complementarios, 16% desde domicilios con servicios de salud organizados, 19% desde un centro de enfermería especializada, 34% desde el centro de rehabilitación y 22% desde un hospital con atención a largo plazo (p <0.001). Los pacientes con estadías en Unidad de Cuidados Intensivos, con más complicaciones postoperatorias y con una hospitalización prolongada tenían más probabilidades de ser dados de alta hacia un domicilio con servicios de salud organizados o hacia un centro de rehabilitación (p <0,001). El alta hospitalaria con servicios organizados de atención médica domiciliaria, centros de enfermería especializada o centros de rehabilitación aumentaron el riesgo de readmisión ajustada de múltiples variables en un 30% (OR 1.3, IC 95% 1.3-1.6), 60% (OR 1.6, IC 95% 1.5-1.8), o 200% (OR 3.0, IC 95% 2.5-3.6), respectivamente. El alta hospitalaria a largo plazo no fué asociada con un mayor riesgo de readmisión ajustada (OR 1.2, IC 95% 0.9-1.6), no obstante que este grupo fué el que tuvo las mayores comorbilidades y complicaciones postoperatorias. Entre los pacientes readmitidos dentro de los 30 días, la mediana del tiempo hasta el reingreso fue significativamente diferente entre el domicilio sin servicios complementarios (7), domicilio con servicios de salud organizados (8), el centro de cuidados de enfermería especializada (8), centros de rehabilitación (9) y hospitales con atención a largo plazo (12) (p <0,001).Naturaleza retrospectiva del presente estudio.El alta hospitalaria con servicios de salud domiciliarios organizados, hacia centros de enfermería especializada o hacia centros de rehabilitación se asocian con un mayor riesgo ajustado de readmisión en comparación con el alta domiciliaria de rutina y los hospitales con atención a largo plazo. Los objetivos potenciales para disminuir la readmisión incluyen mejorar la transición de la atención al momento del alta, mejorar la calidad de la atención después del alta y mejorar las diferentes facilidades para los pacientes.

RESUMO

BACKGROUND: Readmissions reflect adverse patient outcomes, and clinicians currently lack accurate models to predict readmission risk. OBJECTIVE: We sought to create a readmission risk calculator for use in the postoperative setting after elective colon and rectal surgery. DESIGN: Patients were identified from 2012-2014 American College of Surgery-National Surgical Quality Improvement Program data. A model was created with 60% of the National Surgical Quality Improvement Program sample using multivariable logistic regression to stratify patients into low/medium- and high-risk categories. The model was validated with the remaining 40% of the National Surgical Quality Improvement Program sample and 2016-2018 institutional data. SETTINGS: The study included both national and institutional data. PATIENTS: Patients who underwent elective abdominal colon or rectal resection were included. MAIN OUTCOME MEASURES: The primary outcome was readmission within 30 days of surgery. Secondary outcomes included reasons for and time interval to readmission. RESULTS: The model discrimination (c-statistic) was 0.76 ((95% CI, 0.75-0.76); p < 0.0001) in the National Surgical Quality Improvement Program model creation cohort (n = 50,508), 0.70 ((95% CI, 0.69-0.70); p < 0.0001) in the National Surgical Quality Improvement Program validation cohort (n = 33,714), and 0.62 ((95% CI, 0.54-0.70); p = 0.04) in the institutional cohort (n = 400). High risk was designated as ≥8.7% readmission risk. Readmission rates in National Surgical Quality Improvement Program and institutional data were 10.7% and 8.8% overall; of patients predicted to be high risk, observed readmission rate was 22.1% in the National Surgical Quality Improvement Program and 12.4% in the institutional cohorts. Overall median interval from surgery to readmission was 14 days in the National Surgical Quality Improvement Program and 11 days institutionally. The most common reasons for readmission were organ space infection, bowel obstruction/paralytic ileus, and dehydration in both the National Surgical Quality Improvement Program and institutional data. LIMITATIONS: This was a retrospective observational review. CONCLUSIONS: For patients who undergo elective colon and rectal surgery, use of a readmission risk calculator developed for postoperative use can identify high-risk patients for potential amelioration of modifiable risk factors, more intensive outpatient follow-up, or planned readmission.

CREACIÓN Y VALIDACIÓN INSTITUCIONAL DE UNA CALCULADORA DE RIESGO DE REINGRESO PARA CIRUGÍA COLORRECTAL ELECTIVE: Los reingresos reflejan resultados adversos de los pacientes y los médicos actualmente carecen de modelos precisos para predecir el riesgo de reingreso.Intentamos crear una calculadora de riesgo de readmisión para su uso en el entorno postoperatorio después de una cirugía electiva de colon y recto.Los pacientes que se sometieron a una resección electiva del colon abdominal o rectal se identificaron a partir de los datos del Programa Nacional de Mejora de la Calidad Quirúrgica (ACS-NSQIP) del Colegio Americano de Cirugia Nacional 2012-2014. Se creó un modelo con el 60% de la muestra NSQIP utilizando regresión logística multivariable para estratificar a los pacientes en categorías de riesgo bajo / medio y alto. El modelo fue validado con el 40% restante de la muestra NSQIP y datos institucionales 2016-2018.El estudio incluyó datos tanto nacionales como institucionales.El resultado primario fue el reingreso dentro de los 30 días de la cirugía. Los resultados secundarios incluyeron razones e intervalo de tiempo para el reingreso.La discriminación del modelo (estadística c) fue de 0,76 (IC del 95%: 0,75-0,76, p < 0,0001) en la cohorte de creación del modelo NSQIP (n = 50,508), 0,70 (IC del 95%: 0,69-0,70, p < 0,0001) en la cohorte de validación NSQIP (n = 33,714), y 0,62 (IC del 95%: 0,54-0,70, p = 0,04) en la cohorte institucional (n = 400). Alto riesgo se designó como > 8,7% de riesgo de readmisión. Las tasas de readmisión en NSQIP y los datos institucionales fueron del 10,7% y del 8,8% en general; de pacientes con riesgo alto, la tasa de reingreso observada fue del 22.1% en el NSQIP y del 12.4% en las cohortes institucionales. El intervalo medio general desde la cirugía hasta el reingreso fue de 14 días en NSQIP y 11 días institucionalmente. Las razones más comunes para el reingreso fueron infección del espacio orgánico, obstrucción intestinal / íleo paralítico y deshidratación tanto en NSQIP como en datos institucionales.Esta fue una revisión observacional retrospectiva.Para los pacientes que se someten a cirugía electiva de colon y recto, el uso de una calculadora de riesgo de reingreso desarrollada para el uso postoperatorio puede identificar a los pacientes de alto riesgo para una posible mejora de los factores de riesgo modificables, un seguimiento ambulatorio más intensivo o un reingreso planificado.

RESUMO

BACKGROUND: Online physician rating Web sites are used by over half of consumers to select doctors. No studies have examined physician rating Web sites for colon and rectal surgeons. OBJECTIVE: The purpose of this study was to evaluate the accuracy and rating patterns of colon and rectal surgeons on the largest physician rating Web site. DESIGN: Physician characteristics and ratings were collected from a randomly selected sample of 500 from 3043 Healthgrades "colon and rectal surgery specialists." Board certifications were verified with the American Board of Surgery and American Board of Colon and Rectal Surgery Web sites. SETTINGS: Data acquisition was completed on July 18, 2018. PATIENTS: Patients were not directly studied. MAIN OUTCOME MEASURES: The primary outcome was to assess the accuracy of Healthgrades in reporting American Board of Surgery and American Board of Colon and Rectal Surgery certification. The secondary outcome was to identify factors associated with high star ratings. RESULTS: A total of 48 (9.6%) of the 500 sampled were incorrectly identified as practicing US surgeons and excluded from subsequent analysis. Healthgrades showed 80.1% agreement with verified board certifications for American Board of Surgery and 85.4% for American Board of Colon and Rectal Surgery. The mean star rating was 4.2 of 5.0 (SD = 0.9), and 77 (21.6%) had 5-star ratings. In a multivariable logistic model (p < 0.001), 5-star rating was associated with 1 to 9 years (OR = 2.76; p = 0.04) or >40 years in practice (OR = 3.35; p = 0.04) and fewer reviews (OR = 0.88; p < 0.001). There were no significant associations with surgeon sex, age, geographic region, or board certification. LIMITATIONS: Data were limited to a single physician rating Web site. CONCLUSIONS: In the modern age of healthcare consumerism, physician rating Web sites should be used with caution given inaccuracies. More accurate online resources are needed to inform patient decisions in the selection of specialized colon and rectal surgical care. See Video Abstract at http://links.lww.com/DCR/B91. PRECISIÓN DE DATOS Y PREDICTORES DE ALTAS CALIFICACIONES DE CIRUJANOS DE COLON Y RECTO EN UN SITIO WEB DE CALIFICACIÓN MÉDICA EN LÍNEA: Más de la mitad de los consumidores utilizan los sitios web de calificación de médicos en línea para seleccionar médicos. Ningún estudio ha examinado los sitios web de calificación de médicos para cirujanos de colon y recto.Evaluar la precisión y los patrones de calificación de los cirujanos de colon y recto en el sitio web más grande de calificación de médicos.Las características y calificaciones de los médicos se obtuvieron de una muestra seleccionada al azar de 500 de 3,043 "especialistas en cirugía de colon y recto" de Healthgrades. Las certificaciones del Consejo se verificaron en los sitios web del Consejo Americano de Cirugía y del Consejo Americano de Cirugía de Colon y Recto.La adquisición de datos se completó el 18 de julio de 2018.Los pacientes no fueron estudiados directamente.El resultado primario fue evaluar la precisión de Healthgrades al informar la certificación por el Consejo Americano de Cirugía y por el Consejo Americano de Cirugía de Colon y Recto. El resultado secundario fue identificar factores asociados con altas calificaciones en estrellas.Un total de 48 (9.6%) de la muestra de 500 fueron identificados incorrectamente como cirujanos practicantes de EE. UU. y excluidos del análisis subsecuente. Healthgrades mostró un 80.1% de concordancia con las certificaciones verificadas del Consejo Americano de Cirugía y el 85.4% con el Consejo Americano de Cirugía de Colon y Recto. La calificación promedio de estrellas fue 4.2 / 5 (SD 0.9), y 77 (21.6%) tuvieron calificaciones de 5 estrellas. En un modelo logístico multivariable (p <0.001), la calificación de 5 estrellas se asoció con 1-9 años (OR 2.76, p = 0.04) o más de 40 años en la práctica (OR 3.35, p = 0.04) y menos evaluaciones (OR 0.88, p <0.001). No hubo asociaciones significativas con el género, edad, región geográfica o certificación por los Consejos del cirujano.Los datos se limitaron a un solo sitio web de calificación de médicos.En la era moderna del consumismo en atención médica, los sitios web de calificación de los médicos deben usarse con precaución debido a imprecisiones. Se necesitan recursos en línea más precisos para que las decisiones de los pacientes sean informadas en la selección de atención quirúrgica especializada de colon y recto.

RESUMO

BACKGROUND: Acquired haemophilia A (AHA) is an autoimmune bleeding disorder with significant morbidity and mortality. Bleeding AHA patients with high titre inhibitors can be treated with either activated prothrombin complex concentrate (aPCC) or recombinant activated factor VII (rFVIIa). Given that both replacement therapies have inherent benefits and limitations, a cost-effectiveness analysis (CEA) was performed in this population to compare rFVIIa with aPCC. METHODS: In high-titered AHA patients with bleeding treated with either aPCC or rFVIIa, during a 5-day study period, a Markov model was developed such that these patients were transitioned into four different health states: (1) continuous bleeding, (2) thrombosis, (3) stop bleeding and (4) death, with states (2), (3) and (4) modelled as absorbing states. Model parameters, including probabilities, health utility index and costs, were gathered from the medical literature, except for the costs of aPCC and rFVIIa, which were obtained from our institutional data. RESULTS: During the 5-day period, the total treatment cost of rFVIIa was substantially more than the cost of aPCC ($13 635 vs. $1741). The average quality-adjusted life days (QALDs) gained for rFVIIa were slightly lower compared to aPCC (4·08 vs. 4·09). Overall, aPCC prevailed over rFVIIa. Sensitivity analysis confirmed the robustness of the model across tested ranges of all input variables. CONCLUSION: In high-titered AHA patients with bleeding, aPCC is a cost-effective treatment option when compared to rFVIIa. Thus, aPCC may be considered in these patients, if available, and provided there is no clinical contraindication.

RESUMO

BACKGROUND: Hospital readmissions after elective colectomy are costly and potentially preventable. It is unknown whether hospital discharge on a weekend impacts readmission risk. OBJECTIVE: This study aimed to use a national database to determine whether discharge on a weekend versus weekday impacts the risk of readmission, and to determine what discharge-related factors impact this risk. DESIGN: This investigation is a retrospective cohort study. SETTINGS: Data were derived from the University HealthSystem Consortium, PATIENTS:: Adults who underwent elective colectomy from 2011 to 2015 were included. MAIN OUTCOME MEASURES: The primary outcome measured was the 30-day hospital readmission rate. RESULTS: Of the 76,031 patients who survived the index hospitalization, the mean age of the study population was 58 years; half were men and more than 75% were white. Overall, 20,829 (27%) were discharged on the weekend, and the remaining 55,202 (73%) were discharged on weekdays. The overall 30-day readmission rate was 10.5%; 8.9% for those discharged on the weekend vs 11.1% for those discharged during the weekday (unadjusted OR, 0.78; 95% CI, 0.74-0.83). The adjusted readmission risk was lower for patients discharged home without services (routine, without organized home health service) on a weekend compared with on a weekday (adjusted OR, 0.87; 95% CI, 0.81-0.93; readmission rates, 7.4% vs 8.9%, p < 0.001); however, the combination of weekend discharge and the need for home services increased readmission risk (adjusted OR, 1.39; 95% CI, 1.25-1.55; readmission rate, 16.2% vs 8.9%, p < 0.001). Although patients discharged to rehabilitation and skilled nursing facilities were at an increased risk of readmission compared with those discharged to home, there was no additive increase in risk of readmission for weekend discharge. LIMITATIONS: Data did not capture readmission beyond 30 days or to nonindex hospitals. CONCLUSIONS: Patients discharged on a weekend following elective colectomy were at increased risk of readmission compared with patients discharged on a weekday if they required organized home health services. Further prospective studies are needed to identify areas of intervention to improve the discharge infrastructure. See Video Abstract at http://links.lww.com/DCR/A799.

RESUMO

BACKGROUND: Women surgeons are underrepresented in academic surgery and may be subject to implicit gender bias. In colorectal surgery, women comprise 42% of new graduates, but only 19% of Diplomates in the United States. OBJECTIVE: We evaluated the representation of women at the 2017 American Society of Colon and Rectal Surgeons Scientific and Tripartite Meeting and assessed for implicit gender bias. DESIGN: This was a prospective observational study. SETTING: The study occurred at the 2017 Tripartite Meeting. MAIN OUTCOME MEASURES: The primary outcome measured was the percentage of women in the formal program relative to conference attendees and forms of address. METHODS: Female program representation was quantified by role (moderator or speaker), session type, and topic. Introductions of speakers by moderators were classified as formal (using a professional title) or informal (using name only), and further stratified by gender. RESULTS: Overall, 31% of meeting attendees who are ASCRS members were women, with higher percentages of women as Candidates (44%) and Members (35%) compared with Fellows (24%). Women comprised 28% of moderators (n = 26) and 28% of speakers (n = 80). The highest percentage of women moderators and speakers was in education (48%) and the lowest was in techniques and technology (17%). In the 41 of 47 sessions evaluated, female moderators were more likely than male moderators to use formal introductions (68.7% vs 54.0%, p = 0.02). There was no difference when female moderators formally introduced female versus male speakers (73.9% vs 66.7%, p = 0.52); however, male moderators were significantly less likely to formally introduce a female versus male speaker (36.4% vs 59.2%, p = 0.003). LIMITATIONS: Yearly program gender composition may fluctuate. Low numbers in certain areas limit interpretability. Other factors potentially influenced speaker introductions. CONCLUSIONS: Overall, program representation of women was similar to meeting demographics, although with low numbers in some topics. An imbalance in the formality of speaker introductions between genders was observed. Awareness of implicit gender bias may improve gender equity and inclusiveness in our specialty.

RESUMO

We investigated operative course and post-operative findings of patients undergoing primary enucleation for uveal melanoma versus those requiring secondary enucleation after brachytherapy. A retrospective chart review was performed with IRB approval on patients receiving treatment for uveal melanoma. Patients with enucleation as initial treatment and patients enucleated after plaque brachytherapy were analyzed for demographic data, operative course, and post-enucleation outcome. Further cause analysis for secondary enucleations was investigated. No significant difference was seen in age, laterality, or gender between the primarily enucleated (n = 54) and secondarily enucleated (n = 34) groups. Greater difficulty with surgery was noted in 28/32 (87.5%) of secondary enucleations compared to 1/54 (1.8%) of primary enucleations (p < 0.0001). Operative time was >2 hours in 3/51 (6%) of primary enucleations (vs. 8 of 32, 25%, p = 0.02). Average implant size was similar in the 2 groups (20.6 mm), however 2/34 (6%) of secondary enucleations required dermis fat grafting. Post-enucleation anophthalmic ptosis occurred after 8/49 (16%) of primary cases (vs. 13/30, 43%, p = 0.02) and prosthetic enophthalmos after none (0%) of primary cases (vs. 5/30, 17%, p = 0.006). Class 2 gene expression profile was found in 6/8 (60%) of eyes enucleated for treatment failure. Secondary enucleation performed after plaque brachytherapy was technically more difficult, and had more anophthalmic socket and eyelid complications compared to primary enucleation for uveal melanoma. Primary enucleation may avoid additional surgery and morbidity in a subset of patients with contraindications to plaque brachytherapy.

RESUMO

OBJECTIVE: Results of a large multicenter randomized clinical trial published in 2007 demonstrated no benefit in using a liberal versus conservative RBC transfusion threshold in stable critically ill children. Using the conservative threshold decreased the number of RBC transfusions without increasing adverse outcomes. We aimed to determine if wide dissemination of this evidence altered the hemoglobin threshold used for RBC transfusions in our pediatric medical-surgical ICU. DESIGN: Before-after retrospective cohort study using multiple administrative databases and chart review. SETTING: PICU serving medical and surgical patients. PATIENTS: All potentially stable children receiving a RBC transfusion in the PICU in 2006 (prepublication) and in 2009-2010 (postpublication). Children were considered unstable and excluded if they were severely hypoxic, receiving renal replacement therapy, hemodynamically unstable, or bleeding. INTERVENTIONS: Physician education on evidence supporting hemoglobin transfusion thresholds in teaching conferences, staff meetings, and via e-mail. MEASUREMENTS AND MAIN RESULTS: In 2006, 14.6% of patients (n = 285/1,940) received a RBC transfusion. In 2009-2010, 12.1% of patients (n = 551/4,542) received a RBC transfusion. We evaluated patients transfused when they were potentially clinically stable, including 145 children in 2006 (191 transfusion days) and 266 children in 2009-2010 (369 transfusion days). We found no significant differences in age, sex, race, diagnoses, postoperative status, illness severity scores, mortality, or length of stay between these two groups. The median hemoglobin transfusion threshold decreased significantly from 8.0 g/dL (interquartile range 7.3, 8.6 g/dL) in 2006 to 7.5 g/dL (interquartile range 6.9, 8.1 g/dL) in 2009-2010 (p = 0.001). The percentage of transfusion days using a hemoglobin threshold more than 7 g/dL decreased from 81% (n = 154) in 2006 to 71% (n = 261) in 2009-2010. CONCLUSION: Although transfusion thresholds in potentially stable critically ill children in our PICU significantly decreased after dissemination of best available evidence, 71% of patients were transfused at a hemoglobin threshold more than 7 g/dL.

RESUMO

Antifungal agents may be associated with significant toxicity or drug interactions leading to sub-therapeutic antifungal drug concentrations and poorer clinical outcomes for patients with haematological malignancy. These risks may be minimised by clinical assessment, laboratory monitoring, avoidance of particular drug combinations and dose modification. Specific measures, such as the optimal timing of oral drug administration in relation to meals, use of pre-hydration and electrolyte supplementation may also be required. Therapeutic drug monitoring (TDM) of antifungal agents is warranted, especially where non-compliance, non-linear pharmacokinetics, inadequate absorption, a narrow therapeutic window, suspected drug interaction or unexpected toxicity are encountered. Recommended indications for voriconazole and posaconazole TDM in the clinical management of haematology patients are provided. With emerging knowledge regarding the impact of pharmacogenomics upon metabolism of azole agents (particularly voriconazole), potential applications of pharmacogenomic evaluation to clinical practice are proposed.

RESUMO

OBJECTIVES: This review aims to explore and thematically synthesize the existing literature on safety culture within the context of radiology. The primary objective is to identify key practices that effectively strengthen safety culture, highlighting the pivotal roles of leadership, effective teamwork, and interprofessional collaboration in these efforts. The review intends to showcase actionable recommendations that are particularly relevant to the radiology setting. KEY FINDINGS: The study highlights that effective leadership is fundamental in establishing and nurturing a safety-first approach within radiology departments. Key practices for promoting a safety culture include safety huddles, leadership walkarounds, quality learning boards, intentional patient rounding (frequent patient-care provider interactions), morbidity and mortality meetings, and multidisciplinary team rounds. These practices have been found to facilitate open communication and transparency, which are crucial elements in creating a sustainable safety culture. Additionally, the study underscores the significant role of radiology managers in driving these safety initiatives and acting as facilitators for a culture of safety, focused on long-term excellence and continuous improvement. CONCLUSION: The study concludes that a multifaceted and comprehensive approach is vital for fostering a safety culture in radiology departments, with a focus on sustainable excellence in patient care. The leadership role is critical in this process, with radiology managers being instrumental in implementing and maintaining effective safety practices. IMPLICATIONS FOR PRACTICE: This study provides best practices for sustainable safety culture in radiology departments. It advocates for healthcare managers to adopt and integrate these identified practices into their operational strategies. Continuous professional development, focusing on safety and quality in patient care, and fostering a collaborative environment for open discussion and learning from safety incidents are essential for the continued advancement and excellence of healthcare services.
