Background: While spontaneous coronary artery dissection (SCAD) patients can present with ventricular arrhythmias (VAs), the in-hospital outcomes among these patients are not well-established. Objective: This study aimed to analyze the in-hospital outcomes of patients with SCAD and concurrent VAs, and to determine the predictors of VAs occurrence in this population. Methods: Using the Nationwide Readmissions Database, our study included patients aged 18 years or older who had SCAD between 2017 and 2020. We categorized the cohort into two groups depending on the presence of VAs during hospitalization. The in-hospital outcomes were assessed between two groups. Through multivariable analysis, we further analyzed the predictors of VAs occurrence among SCAD patients. Results: Our study included 160 (13.45%) SCAD patients with concurrent VAs and 1,030 (86.55%) SCAD patients without concurrent VAs between 2017 and 2020. SCAD patients with concurrent VA were associated with higher rates of early mortality (11.88% vs. 2.04%, p<0.01), prolonged index hospital stay (≥7 days) (31.25% vs. 12.82%, p<0.01), and non-home discharge (21.88% vs. 6.50%, p<0.01). The length of hospital stay was longer in the SCAD with concurrent VAs group (6.93 days vs. 3.73 days, p<0.01), and the median cumulative cost of hospitalization was also higher in this group ($31,450 vs. $14,664, p<0.01). SCAD with concurrent VAs patients also had poorer in-hospital adverse events. In multivariable analysis, the independent predictors for VAs occurrence among SCAD patients were chronic liver disease (aOR: 2.18; 95% CI: 1.15- 4.12, p=0.02) and heart failure (aOR: 3.40; 95%CI: 2.30- 5.02, p<0.01). Conclusion: Ventricular arrhythmias among SCAD patients were associated with poorer in-hospital outcomes. Heart failure and chronic liver disease were the predictors of VAs in SCAD patients. This highlights the importance of closely monitor and aggressive VAs management among these high-risk patients.

AbstractBackgroundWe sought to characterize and compare late patient‐reported outcomes (PROs) after moderately hypofractionated intensity modulated radiation therapy (IMRT) and proton beam therapy (PBT) for localized prostate cancer (PC).MethodsThis multi‐institutional analysis included low‐ or intermediate‐risk group PC patients treated with moderately hypofractionated radiation to an intact prostate stratified by treatment modality: IMRT or PBT. The primary outcomes were prospectively collected patient‐reported late gastrointestinal (GI) and genitourinary (GU) toxicity assessed by International Prostate Symptom Score (IPSS) and Expanded PC Index Composite (EPIC). Multivariable regression analysis (MVA) controlling for age, race, and risk group tested the effect of time, treatment, and their interaction.Results287 IMRT and 485 PBT patients were included. Intermediate risk group (81.2 vs. 68.2%; p < 0.001) and median age at diagnosis (70 vs. 67 years; p < 0.001) were higher in the IMRT group. On MVA, there was no significant difference between modalities. PBT IPSS did not differ from IMRT IPSS at 12 months (odds ratio [OR], 1.19; p = 0.08) or 24 months (OR, 0.99; p = 0.94). PBT EPIC overall GI function at 12 months (OR, 3.68; p = 0.085) and 24 months (OR 2.78; p = 0.26) did not differ from IMRT EPIC overall GI function. At 24 months, urinary frequency was no different between PBT and IMRT groups (OR 0.35; p = 0.096).ConclusionsThis multi‐institutional analysis of low‐ or intermediate‐risk PC treated with moderately hypofractionated PBT and IMRT demonstrated low rates of late patient‐reported GI and GU toxicities. After covariate adjustment, late GI and GU PROs were not significantly different between PBT or IMRT cohorts.

Study Design: Retrospective review of a prospectively maintained database. Objective: Assess differences in preoperative status and postoperative outcomes among patients of different educational backgrounds undergoing surgical management of cervical spondylotic myelopathy (CSM). Summary of Background Data: Patient education level (EL) has been suggested to correlate with health literacy, disease perception, socioeconomic status (SES), and access to health care. Methods: The CSM data set of the Quality Outcomes Database (QOD) was queried for patients undergoing surgical management of CSM. EL was grouped as high school or below, graduate-level, and postgraduate level. The association of EL with baseline disease severity (per patient-reported outcome measures), symptoms >3 or ≤3 months, and 24-month patient-reported outcome measures were evaluated. Results: Among 1141 patients with CSM, 509 (44.6%) had an EL of high school or below, 471 (41.3%) had a graduate degree, and 161 (14.1%) had obtained postgraduate education. Lower EL was statistically significantly associated with symptom duration of >3 months (odds ratio=1.68), higher arm pain numeric rating scale (NRS) (coefficient=0.5), and higher neck pain NRS (coefficient=0.79). Patients with postgraduate education had statistically significantly lower Neck Disability Index (NDI) scores (coefficient=-7.17), lower arm pain scores (coefficient=−1), and higher quality-adjusted life-years (QALY) scores (coefficient=0.06). Twenty-four months after surgery, patients of lower EL had higher NDI scores, higher pain NRS scores, and lower QALY scores (P<0.05 in all analyses). Conclusions: Among patients undergoing surgical management for CSM, those reporting a lower educational level tended to present with longer symptom duration, more disease-inflicted disability and pain, and lower QALY scores. As such, patients of a lower EL are a potentially vulnerable subpopulation, and their health literacy and access to care should be prioritized.

AbstractExtended oral antibiotic prophylaxis (EOAP) has been suggested to reduce rates of periprosthetic joint infection (PJI) postoperatively after total joint arthroplasty (TJA). The purpose of this multicenter study is to define how many TJA patients are considered high risk for developing PJI based on published EOAP criteria and determine whether this status is associated with socioeconomic or demographic factors. All primary and aseptic revision TJAs performed in 2019 at three academic medical centers were reviewed. High-risk status was defined based on prior published EOAP criteria. Area deprivation index (ADI) was calculated as a measure of socioeconomic status. Data were reported as means with standard deviation. Both overall and institutional differences were compared. Of the 2,511 patients (2,042 primary and 469 revision) in this cohort, 73.3% met criteria for high risk (primary: 72.9% [1,490] and revision: 74.6% [350]). Patient's race or age did not have a significant impact on risk designation; however, a larger proportion of high-risk patients were women (p = 0.002) and had higher Elixhauser scores (p < 0.001). The mean ADI for high-risk patients was higher (more disadvantaged) than for standard-risk patients (64.0 [20.8] vs. 59.4 [59.4]) (p < 0.001). Over 72% of primary and revision TJA patients at three medical centers met published criteria for EOAP. These patients were more often women, had more comorbidities, and lived in more disadvantaged areas. Our findings suggest that most patients qualify for EOAP, which may call for more stringent criteria on who would benefit extended antibiotic prophylaxis.

BACKGROUND: Using standard anterior approaches, consistent R0 resection of locally advanced primary and recurrent rectal and anal cancer involving the deep pelvic sidewall may be unattainable. Therefore, to improve R0 resection rates, we have used a posterior-first, then anterior 2-stage approach to resection of tumors in this location. OBJECTIVE: To assess the R0 resection rate and surgical outcomes of the first 10 patients operated on using this approach. DESIGN: We conducted a retrospective case series review of our prospectively maintained surgical pathology and tumor registries. SETTING: This study was conducted at the Mayo Clinic in Rochester, Minnesota. PATIENTS: Ten patients (6 female individuals, median age 53.5 years) with primary or recurrent anal or rectal cancer treated with a posterior-first, then anterior 2-stage approach were identified. MAIN OUTCOME MEASURES: The primary outcome measures were the R0 resection rate and surgical outcomes. RESULTS: An R0 resection was achieved in all 10 patients. Nine patients developed 1 or more 30-day Clavien-Dindo grade III complications. Nine patients developed gluteal wound complications ranging from superficial wound dehiscence to flap necrosis. During the follow-up period, 4 patients were found to have metastatic disease and 1 patient had local re-recurrence. LIMITATIONS: Small cohort with heterogeneous tumors and a short follow-up duration. CONCLUSION: A posterior-first, then anterior 2-stage approach has allowed us to achieve consistent R0 resection margins in locally advanced primary and recurrent rectal and anal cancers involving the deep pelvic sidewall. Poor wound healing of the posterior gluteal incision is a common complication. See Video Abstract. MEJORANDO LAS TASAS DE RESECCIÓN R0 CON UN ABORDAJE DE DOS ETAPAS PRIMERO POSTERIOR PARA LA RESECCIÓN EN BLOQUE DE CÁNCERES ANORRECTALES PRIMARIOS Y RECURRENTES LOCALMENTE AVANZADOS QUE AFECTAN LA PARED LATERAL PÉLVICA PROFUNDA ANTECEDENTES: Utilizando abordajes anteriores estándares, la resección R0 consistente del cáncer de recto y ano primario y recurrente localmente avanzado involucrando la pared lateral pélvica profunda puede ser inalcanzable. Por lo tanto, para mejorar las tasas de resección R0, hemos empleado un abordaje de 2 etapas primero posterior y luego anterior para la resección de tumores en esta ubicación. OBJETIVO: Este estudio tuvo como objetivo evaluar la tasa de resección R0 y los resultados quirúrgicos de los primeros 10 pacientes operados con este abordaje. DISEÑO: Realizamos una revisión retrospectiva de series de casos de nuestros registros de patología quirúrgica y tumores mantenidos prospectivamente. AJUSTE: Este estudio se realizó en la Clínica Mayo en Rochester, Minnesota, EE. UU. PACIENTES: Se identificaron diez pacientes (6 mujeres, mediana de edad 53.5 años) con cáncer anal o rectal primario o recurrente tratados con un abordaje de dos etapas, primero posterior y luego anterior. PRINCIPALES MEDIDAS DE RESULTADO: Las medidas de resultado primarias fueron la tasa de resección R0 y los resultados quirúrgicos. RESULTADOS: Se logró una resección R0 en los 10 pacientes. Nueve pacientes desarrollaron una o más complicaciones de grado III de Clavien-Dindo a los 30 días. Nueve pacientes desarrollaron complicaciones de la herida del glúteo que variaron desde dehiscencia superficial de la herida hasta necrosis del colgajo. Durante el período de seguimiento, se encontró que 4 pacientes tenían enfermedad metastásica y un paciente tuvo recurrencia local. LIMITACIONES: Cohorte pequeño con tumores heterogéneos y corta duración de seguimiento. CONCLUSIÓN: Un abordaje en 2 etapas, primero posterior y luego anterior, nos ha permitido lograr márgenes de resección R0 consistentes en cánceres de recto y anal primarios y recurrentes localmente avanzados que afectan la pared lateral pélvica profunda. La mala cicatrización de la incisión glútea posterior es una complicación común. (Traducción—Dr. Aurian Garcia Gonzalez)

SummaryAmong 210 patients with myelodysplastic syndromes (MDSs) with del(5q), molecular information was available at diagnosis or at least 3 months before leukaemic transformation in 146 cases. Multivariate analysis identified therapy‐related setting (p = 0.02; HR 2.3) and TP53 variant allele frequency (VAF) ≥22% (p < 0.01; HR 2.8), but not SF3B1 mutation (p = 0.65), as independent risk factors for survival. Median survival was 11.7 versus 4 years (5/10‐year survival 73%/52% vs. 42%/14%) in the absence (N = 112) versus presence (N = 34) of ≥1 risk factors; leukaemia‐free survival was affected by TP53 VAF ≥22% (p < 0.01). Such information might inform treatment decision‐making in MDS‐del(5q) regarding allogeneic stem cell transplant.
