RESUMO
Background: Increasing demand for shoulder arthroplasty and an aging population may increase the rate of complications associated with advanced age such as postoperative delirium, but little is known on its burden in this cohort. Purpose: We sought to answer the following questions: (1) What is the epidemiology of postoperative delirium after shoulder arthroplasty? (2) What modifiable risk factors can be identified for postoperative delirium after shoulder arthroplasty? (3) Do risk factors differ in those younger than and in those older than 70 years of age? Methods: In a retrospective nationwide cohort study, we extracted data from the Premier Healthcare database on inpatient total and reverse shoulder arthroplasties from 2006 to 2016. The primary outcome was postoperative delirium; modifiable risk factors of interest were perioperative opioid use (high, medium, or low), peripheral nerve block use, and perioperative prescription medications. Mixed-effects models assessed associations between risk factors and postoperative delirium. Odds ratios and confidence intervals are reported. We applied a cutoff of 70 years of age because it was the median age of the cohort, as well as the age at which we observed that delirium prevalence increased. Results: A total of 92,429 total and reverse shoulder arthroplasties were identified (age range: 14-89 years). Overall delirium prevalence was 3.1% (n = 2909). Age-specific prevalence of postoperative delirium was lower in patients aged 50 to 70 years and higher in those aged 70 years and older, up to 8% among those older than 88 years. After adjusting for relevant covariates, only long-acting and combined short-acting and long-acting benzodiazepines (compared with no benzodiazepines) were associated with increased odds of postoperative delirium. Corticosteroids were associated with decreased odds of postoperative delirium. Conclusion: Our retrospective cohort study demonstrated that benzodiazepine use and older patient age were significantly associated with postoperative delirium in shoulder arthroplasty patients. The relationship between benzodiazepine use and delirium was particularly notable among those 70 years of age and older. Further investigation is indicated, given the known adverse effects of benzodiazepines in older adults and our findings of higher than expected use of these medications in this surgical cohort.
RESUMO
ABSTRACT: Dermatomyositis (DM) is an autoimmune myopathy characterized by proximal muscle weakness and distinct skin findings. DM is associated with an increased risk of malignancy in adults. We describe a case of dermatomyositis with unusually severe oropharyngeal dysphagia and respiratory muscle weakness on presentation, who was found to have underlying metastatic prostate cancer. Prostate cancer is uncommonly associated with DM. The patient tested positive for antitranscription intermediate family-1 (anti-TIF-1, also known as anti-p155/410) antibodies, which are linked to malignancy-associated DM in adults and are associated with dysphagia and more severe cutaneous findings.

PURPOSE: To describe the feasibility, safety and short-term results of prostatic artery embolization (PAE) performed with adjunctive coil embolization of the main prostatic arteries (PA) following particle embolization. MATERIALS AND METHODS: A total of 95 patients who underwent PAE with adjunctive bilateral coil embolization of the PAs following particle embolization between September 2018 and May 2021 were included. The patients had a mean prostate size of 115 ± 64 ml, 18/95 with hematuria symptoms, and 16/95 with indwelling urinary catheters. Coil embolization was performed in the main PAs prior to the bifurcation into the anteromedial and posterolateral branches using detachable microcoils. International Prostate Symptoms Score (IPSS), quality of life (QOL), maximum flow rate (Qmax) and adverse events were recorded. RESULTS: IPSS were improved by - 11.2 ± 7.9 (n = 49, P < 0.001) and QOL by - 2.4 ± 1.8 (n = 49, P < 0.001) over a mean follow-up of 10.7 ± 7.9 weeks. Qmax did not demonstrate statistical significance. Twelve patients with hematuria (67%) showed improvement or resolution and twelve patients with indwelling or intermittent catheters (75%) were no longer catheter dependent. Two patients underwent a repeat PAE. There were no adverse events which were attributable to coil embolization. CONCLUSION: Adjunctive coil embolization of the main PAs following particle embolization is a technically feasible technique with similar short-term clinical outcomes compared to prior studies. This novel technique warrants further prospective investigation with controls.

PURPOSE: In this study, we describe the patterns of hepatocellular carcinoma (HCC) screening with imaging and factors associated with imaging modality selection in a tertiary care transplant center. METHODS: This was a retrospective study where all adult patients with cirrhosis and/or chronic hepatitis B virus infection referred for HCC screening with ultrasound (US), CT or MRI were identified during 2017. The association between imaging methods, demographic/clinical data were analyzed by uni- and multivariate analysis. RESULTS: A total of 1437 patients were included (median age 61y, 59% male, median BMI 27.5 kg/m2, median AFP 3.4 ng/mL, 37% with HCV and 87% with cirrhosis). Index screening imaging method utilization included MRI (51%), US (33%) and CT (16%). Use of US as the index imaging modality for screening was significantly associated with race/ethnicity [Odds Ratio (OR) 1.71-2.01, all p < 0.05] in multivariate analysis. Presence of cirrhosis (OR 0.29, p < 0.001) and referral by a hepatologist (OR 0.23, p < 0.001) were associated with screening with MRI in the multivariate analysis; while gender, age, BMI, etiology and income at ZIP code of residence were not significantly associated with imaging modality selection. HCC was observed in 62 patients (prevalence 4.3%). Rate of HCC detection was significantly higher with MRI vs US (5.9% vs. 1.5%, p = 0.001). CONCLUSION: MRI was the most frequently used modality (> 50%) for HCC screening in our tertiary care center, in contrast with the current practice guidelines. Race/ethnicity, cirrhosis and referral by a hepatologist were associated with the imaging method used for HCC screening.

Introduction Patients with hepatocellular carcinoma (HCC) involving the inferior vena cava (IVC) and/or right atrium (RA) often experience debilitating symptoms, including lower extremity edema, dyspnea on exertion, shortness of breath at rest, chest pain, and ascites, that impact quality of life. The efficacy of external beam radiation therapy (EBRT) in palliating these symptoms is unclear. Thus, we sought to assess the effectiveness of EBRT in the palliation of symptoms and treatment outcomes in this patient population. Materials and methods All patients with HCC that compressed or invaded the IVC, received EBRT, and had a two-month follow-up visit to assess clinical response at our institution between 2010 and 2018 were analyzed. Patient demographics and clinical features were retrieved from the electronic medical record. Local control, local progression-free survival, and overall survival (OS) were measured from the last day of EBRT and calculated using the Kaplan-Meier method. Results Twenty-six patients with invasion or compression of the IVC were identified, 11 of whom (42%) had involvement of the RA. The median follow-up was 3.6 months. Five patients (19%) were treated with stereotactic body radiation therapy (SBRT) (all with five fractions) and 21 patients (81%) were treated with fractionated radiation therapy (range 10-16 fractions), both to a median dose of 3,000 cGy (range 2500-4000 cGy for SBRT, 2500-3750 cGy for fractionated radiation therapy). Significant proportions of patients experienced symptomatic relief from peripheral edema (54%), dyspnea on exertion (57%), shortness of breath (83%), chest pain (67%), and ascites (25%) after receiving EBRT. Additionally, they experienced few toxicities, with zero experiencing grade three or higher toxicities. One-year and two-year local control rates were 11.5% and 7.7%, respectively, and the median local progression-free survival was 4.8 months. One-year and two-year OS rates were 38.4% and 38.4%, respectively. Conclusions Our results suggest that EBRT should be considered as a potential treatment option for patients with HCC invading or compressing the IVC with or without involvement of the RA. EBRT was very well-tolerated and effectively palliated a variety of symptoms in patients with advanced disease.
RESUMO
PURPOSE: To train a deep learning classification algorithm to predict chest radiograph severity scores and clinical outcomes in patients with coronavirus disease 2019 (COVID-19). MATERIALS AND METHODS: In this retrospective cohort study, patients aged 21-50 years who presented to the emergency department (ED) of a multicenter urban health system from March 10 to 26, 2020, with COVID-19 confirmation at real-time reverse-transcription polymerase chain reaction screening were identified. The initial chest radiographs, clinical variables, and outcomes, including admission, intubation, and survival, were collected within 30 days (n = 338; median age, 39 years; 210 men). Two fellowship-trained cardiothoracic radiologists examined chest radiographs for opacities and assigned a clinically validated severity score. A deep learning algorithm was trained to predict outcomes on a holdout test set composed of patients with confirmed COVID-19 who presented between March 27 and 29, 2020 (n = 161; median age, 60 years; 98 men) for both younger (age range, 21-50 years; n = 51) and older (age >50 years, n = 110) populations. Bootstrapping was used to compute CIs. RESULTS: The model trained on the chest radiograph severity score produced the following areas under the receiver operating characteristic curves (AUCs): 0.80 (95% CI: 0.73, 0.88) for the chest radiograph severity score, 0.76 (95% CI: 0.68, 0.84) for admission, 0.66 (95% CI: 0.56, 0.75) for intubation, and 0.59 (95% CI: 0.49, 0.69) for death. The model trained on clinical variables produced an AUC of 0.64 (95% CI: 0.55, 0.73) for intubation and an AUC of 0.59 (95% CI: 0.50, 0.68) for death. Combining chest radiography and clinical variables increased the AUC of intubation and death to 0.88 (95% CI: 0.79, 0.96) and 0.82 (95% CI: 0.72, 0.91), respectively. CONCLUSION: The combination of imaging and clinical information improves outcome predictions.Supplemental material is available for this article.© RSNA, 2020.
RESUMO
BACKGROUND: Recent studies have demonstrated a complex interplay between comorbid cardiovascular disease, COVID-19 pathophysiology, and poor clinical outcomes. Coronary artery calcification (CAC) may therefore aid in risk stratification of COVID-19 patients. METHODS: Non-contrast chest CT studies on 180 COVID-19 patients ≥ age 21 admitted from March 1, 2020 to April 27, 2020 were retrospectively reviewed by two radiologists to determine CAC scores. Following feature selection, multivariable logistic regression was utilized to evaluate the relationship between CAC scores and patient outcomes. RESULTS: The presence of any identified CAC was associated with intubation (AOR: 3.6, CI: 1.4-9.6) and mortality (AOR: 3.2, CI: 1.4-7.9). Severe CAC was independently associated with intubation (AOR: 4.0, CI: 1.3-13) and mortality (AOR: 5.1, CI: 1.9-15). A greater CAC score (UOR: 1.2, CI: 1.02-1.3) and number of vessels with calcium (UOR: 1.3, CI: 1.02-1.6) was associated with mortality. Visualized coronary stent or coronary artery bypass graft surgery (CABG) had no statistically significant association with intubation (AOR: 1.9, CI: 0.4-7.7) or death (AOR: 3.4, CI: 1.0-12). CONCLUSION: COVID-19 patients with any CAC were more likely to require intubation and die than those without CAC. Increasing CAC and number of affected arteries was associated with mortality. Severe CAC was associated with higher intubation risk. Prior CABG or stenting had no association with elevated intubation or death.

STUDY DESIGN: Retrospective analysis of clinical data from a single institution. OBJECTIVE: The objective of this study was to assess the time of surgery as a possible predictor for outcomes, length of stay, and cost following microdiscectomy. SUMMARY OF BACKGROUND DATA: The volume of microdiscectomy procedures has increased year over year, heightening interest in surgical outcomes. Previous investigations have demonstrated an association between time of procedures and clinical outcomes in various surgeries, however, no study has evaluated its influence on microdiscectomy. METHODS: Demographic and outcome variables were collected from all patients that underwent a nonemergent microdiscectomy between 2008 and 2016. Patients were divided into 2 cohorts: those receiving surgery before 2 pm were assigned to the early group and those with procedures beginning after 2 pm were assigned to the late group. Outcomes and patient-level characteristics were compared using bivariate, multivariable logistic, and linear regression models. Adjusted length of stay and cost were coprimary outcomes. Secondary outcomes included operative complications, nonhome discharge, postoperative emergency department visits, or readmission rates. RESULTS: Of the 1261 consecutive patients who met the inclusion criteria, 792 were assigned to the late group and 469 were assigned to the early group. There were no significant differences in demographics or baseline characteristics between the 2 cohorts. In the unadjusted analysis, mean length of stay was 1.80 (SD=1.82) days for the early group and 2.00 (SD=1.70) days for the late group (P=0.054). Mean direct cost for the early cohort was $5088 (SD=$4212) and $4986 (SD=$2988) for the late cohort (P=0.65). There was no difference in adjusted length of stay or direct cost. No statistically significant differences were found in operative complications, nonhome discharge, postoperative emergency department visits, or readmission rates between the 2 cohorts. CONCLUSION: The study findings suggest that early compared with late surgery is not significantly predictive of surgical outcomes following microdiscectomy.

RATIONALE AND OBJECTIVES: This study seeks to quantify the financial impact of COVID-19 on radiology departments, and to describe the structure of both volume and revenue recovery. MATERIALS AND METHODS: Radiology studies from a large academic health system were retrospectively studied from the first 33 weeks of 2020. Volume and work relative value unit (wRVU) data were aggregated on a weekly basis for three periods: Presurge (weeks 1-9), surge (10-19), and recovery (20-33), and analyzed compared to the pre-COVID baseline stratified by modality, specialty, patient service location, and facility type. Mean and median wRVU per study were used as a surrogate for case complexity. RESULTS: During the pandemic surge, case volumes fell 57%, while wRVUs fell by 69% relative to the pre-COVID-19 baseline. Mean wRVU per study was 1.13 in the presurge period, 1.03 during the surge, and 1.19 in the recovery. Categories with the greatest mean complexity declines were radiography (-14.7%), cardiothoracic imaging (-16.2%), and community hospitals overall (-15.9%). Breast imaging (+6.5%), interventional (+5.5%), and outpatient (+12.1%) complexity increased. During the recovery, significant increases in complexity were seen in cardiothoracic (0.46 to 0.49), abdominal (1.80 to 1.91), and neuroradiology (2.46 to 2.56) at stand-alone outpatient centers with similar changes at community hospitals. At academic hospitals, only breast imaging complexity remained elevated (1.32 from 1.17) during the recovery. CONCLUSION: Reliance on volume alone underestimates the financial impact of the COVID-19 pandemic as there was a disproportionate loss in high-RVU studies. However, increased complexity of outpatient cases has stabilized overall losses during the recovery.

PURPOSE: We describe the presenting characteristics and hospital course of 11 novel coronavirus (COVID-19) patients who developed spontaneous subcutaneous emphysema (SE) with or without pneumomediastinum (SPM) in the absence of prior mechanical ventilation. MATERIALS AND METHODS: A total of 11 non-intubated COVID-19 patients (8 male and 3 female, median age 61 years) developed SE and SPM between March 15 and April 30, 2020 at a multi-center urban health system in New York City. Demographics (age, gender, smoking status, comorbid conditions, and body-mass index), clinical variables (temperature, oxygen saturation, and symptoms), and laboratory values (white blood cell count, C-reactive protein, D-dimer, and peak interleukin-6) were collected. Chest radiography (CXR) and computed tomography (CT) were analyzed for SE, SPM, and pneumothorax by a board-certified cardiothoracic-fellowship trained radiologist. RESULTS: Eleven non-intubated patients developed SE, 36% (4/11) of whom had SE on their initial CXR. Concomitant SPM was apparent in 91% (10/11) of patients, and 45% (5/11) also developed pneumothorax. Patients developed SE on average 13.3 days (SD: 6.3) following symptom onset. No patients reported a history of smoking. The most common comorbidities included hypertension (6/11), diabetes mellitus (5/11), asthma (3/11), dyslipidemia (3/11), and renal disease (2/11). Four (36%) patients expired during hospitalization. CONCLUSION: SE and SPM were observed in a cohort of 11 non-intubated COVID-19 patients without any known cause or history of invasive ventilation. Further investigation is required to elucidate the underlying mechanism in this patient population.

BACKGROUND: Existing research about surgical start time is equivocal about associations between outcomes and late start times, and there is only one published report investigating start time in spine surgery. Therefore, the objective of this study was to assess associations between surgical start time, length of stay (LOS), and cost in lumbar spine surgery. METHODS: Patients at a single institution undergoing posterior lumbar fusion (PLF) were grouped based on whether they received their surgery before or after 2 pm, with those receiving their surgery between 12 am and 6 am and receiving surgery for tumors, trauma, or infections being excluded. These 2 groups were then compared on the basis of demographics and outcomes with cost and LOS as the coprimary outcomes. RESULTS: A total of 2977 patients underwent PLF during the study period. There were minimal differences in preoperative characteristics of the cohorts. The patients who underwent PLF starting after 2 pm had longer LOS (0.45 days; 95% confidence interval [CI], 0.18-0.72; P = 0.001) and higher costs ($1343; 95% CI, $339-$2348; P = 0.009) than cases starting before 2 pm The late surgical start cohort also had higher rates of nonhome discharge (29.73% vs. 23.17%, P = 0.0004), and 30-day (4.36% vs. 2.5%, P = 0.01) and 90-day emergency department visits (5.72% vs. 2.94%, P = 0.0005). CONCLUSIONS: Late surgical start time is associated with longer LOS and higher cost in patients undergoing PLF.

Background Chest radiography has not been validated for its prognostic utility in evaluating patients with coronavirus disease 2019 (COVID-19). Purpose To analyze the prognostic value of a chest radiograph severity scoring system for younger (nonelderly) patients with COVID-19 at initial presentation to the emergency department (ED); outcomes of interest included hospitalization, intubation, prolonged stay, sepsis, and death. Materials and Methods In this retrospective study, patients between the ages of 21 and 50 years who presented to the ED of an urban multicenter health system from March 10 to March 26, 2020, with COVID-19 confirmation on real-time reverse transcriptase polymerase chain reaction were identified. Each patient's ED chest radiograph was divided into six zones and examined for opacities by two cardiothoracic radiologists, and scores were collated into a total concordant lung zone severity score. Clinical and laboratory variables were collected. Multivariable logistic regression was used to evaluate the relationship between clinical parameters, chest radiograph scores, and patient outcomes. Results The study included 338 patients: 210 men (62%), with median age of 39 years (interquartile range, 31-45 years). After adjustment for demographics and comorbidities, independent predictors of hospital admission (n = 145, 43%) were chest radiograph severity score of 2 or more (odds ratio, 6.2; 95% confidence interval [CI]: 3.5, 11; P < .001) and obesity (odds ratio, 2.4 [95% CI: 1.1, 5.4] or morbid obesity). Among patients who were admitted, a chest radiograph score of 3 or more was an independent predictor of intubation (n = 28) (odds ratio, 4.7; 95% CI: 1.8, 13; P = .002) as was hospital site. No significant difference was found in primary outcomes across race and ethnicity or those with a history of tobacco use, asthma, or diabetes mellitus type II. Conclusion For patients aged 21-50 years with coronavirus disease 2019 presenting to the emergency department, a chest radiograph severity score was predictive of risk for hospital admission and intubation. © RSNA, 2020 Online supplemental material is available for this article.

STUDY DESIGN: Retrospective study of a surgical cohort from a single, large academic institution. OBJECTIVE: The aim of this study was to investigate associations between surgical start time, length of stay, cost, perioperative outcomes, and readmission. SUMMARY OF BACKGROUND DATA: One retrospective study with a smaller cohort investigated associations between surgical start time and outcomes in spine surgery and found that early start times were correlated with shorter length of stay. No examinations of perioperative outcomes or cost have been performed. METHODS: All patients undergoing anterior cervical discectomy and fusion (ACDF) and posterior cervical decompression and fusion (PCDF) were queried from a single institution from January 1, 2008 to November 30, 2016. Patients undergoing surgery that started between 12:00 AM and 6:00 AM were excluded due to their likely emergent nature. Cases starting before and after 2:00 PM were compared on the basis of length of stay and cost as the primary outcomes using multivariable logistic regression. RESULT: The patients undergoing ACDF and PCDF were both similar on the basis of comorbidity burden, preoperative diagnosis, and number of segments fused. The patients undergoing ACDF starting after 2 PM had longer LOS values (adjusted difference of 0.65 days; 95% confidence interval [CI]: 0.28-1.03; Pâ=â0.0006) and higher costs of hospitalization (adjusted difference of $1177; 95% CI: $549-$1806; Pâ=â0.0002). Patients undergoing PCDF starting after 2 PM also had longer LOS values (adjusted difference of 1.19 days; 95% CI: 0.46-1.91; Pâ=â0.001) and higher costs of hospitalization (adjusted difference of $2305; 95% CI: $826-$3785; Pâ=â0.002). CONCLUSION: Later surgical start time is associated with longer LOS and higher cost. These findings should be further confirmed in the spine surgical literature to investigate surgical start time as a potential cost-saving measure. LEVEL OF EVIDENCE: 3.

PURPOSE: There are reports investigating the effect of surgical start time (SST) on outcomes, length of stay (LOS) and cost in various surgical disciplines. However, this has not been studied in spine deformity surgery to date. This study compares outcomes for patients undergoing spinal deformity surgery based on SST. METHODS: Patients at a single academic institution from 2008 to 2016 undergoing elective spinal deformity surgery (defined as fusing ≥ 7 segments) were divided by SST before or after 2 PM. Co-primary outcomes were LOS and direct costs. Secondary outcomes included delayed extubation, ICU stay, complications, reoperation, non-home discharge, and readmission rates. RESULTS: There were 373 surgeries starting before 2 PM and 79 after 2 PM. The cohorts had similar demographics including age, sex, comorbidity burden, and levels fused. The late SST cohort had shorter operation durations (p = 0.0007). Multivariable linear regression showed no differences in LOS (estimate 0.4 days, CI - 1.2 to 2.0, p = 0.64) or direct cost (estimate $3652, 95% CI - $1449 to $8755, p = 0.16). Multivariable logistic regression revealed the late SST cohort was more likely to have delayed extubation (OR 2.6, 95% CI 1.4-4.9, p = 0.004) and non-home discharge (OR 2.2, 95% CI 1.1-4.2, p = 0.03). All other secondary outcomes were non-significant. CONCLUSION: Patients undergoing spinal deformity surgery before and after 2 PM have similar LOS and cost of care. However, the late SST cohort had increased likelihood of delayed extubation and non-home discharges, which increase cost in bundled payment models. These findings can be utilized in OR scheduling to optimize outcomes and minimize cost.

RESUMO
This retrospective report describes treatment of 21 patients who underwent prostatic artery embolization using 70- to 150-µm radiopaque microspheres for lower urinary tract symptoms secondary to benign prostatic hyperplasia. Seventeen patients (81%) received successful bilateral prostatic artery embolization. At a mean follow-up of 42 days (range, 25-59 days), patients showed improvement in International Prostate Symptom Score (n = 11; mean = 10.6; P = .001), quality of life score (n = 17; mean = 2.0; P = .02), and International Index of Erectile Function (n = 17; mean = 9.3; P = .01). The mean prostate volume reduction was 28 mL (16.2%; P = .003). Nontarget embolization occurred twice, resulting in 1 minor adverse event of hematospermia.
