43; P = .0002), ASES (32 vs. 43; P = .001), SST (3.5 vs. 4.6; P = .04), and SANE (34 vs. 38; P = .35). Postoperative scores were worse for smokers compared with nonsmokers WORC (79 vs. 89; P = .001), ASES (82 vs. 89; P = .04), SST (9.0 vs. 10.2; P = .02), and SANE (84 vs. 89; P = .09). There were no significant differences in change in scores over time or percentage of patients achieving the minimal clinically important difference of the score between groups. CONCLUSIONS From examining the patients’ subjective patient-determined outcome scores, it does not appear that rotator cuff repair should be strictly contraindicated in active smokers. Postoperative improvements in smokers were similar to nonsmokers. Smokers have lower baseline preoperative and postoperative outcome scores compared with nonsmokers. BACKGROUND Pertussis is an important cause of hospitalization in children. Limited data on pertussis have been reported from China. The aim of this study was to characterize clinically suspected pertussis attributable to Bordetella pertussis among children and determine factors associated with longer duration of hospital stay in B. pertussis infection. METHODS Two hundred and seventeen consecutive children with clinically suspected pertussis were prospectively enrolled in the study between Jan 2016 through Aug 2017. Variables assessed included demographics, clinical symptoms and laboratory findings. Cox proportional hazards regression model were used to predict variables associated with longer duration of hospital stay. RESULTS Among the 217 patients with clinically suspected pertussis, B. pertussis was found in 106 (48.8%) patients. Of the 106 children with B. pertussis infection, 63 (59.4%) patients had coinfections with majority due to rhinovirus (HRV) (30.2%), Mycoplasma pneumoniae (29.2%) and human bocavirus (hBoV) (11.3%). Presence of coinfection [odds ratio (OR) 1.73, CI 1.17-2.54], age ≤ 3 months (OR 1.51, CI 1.09 to 2.27), and WBC count ≥30 × 109/L (OR 1.66, CI 1.07 to 2.84) were independently associated with a longer hospital stay. CONCLUSIONS B. pertussis infection had a high coinfection rate with the majority of coinfections due to HRV, M. pneumoniae and hBoV. Presence of coinfection, Age ≤3 months and WBC count ≥30 × 109/L were associated with a longer hospital stay. Children admitted with pertussis need close monitoring when they had evidence of coinfection, Age ≤3 months, WBC count ≥30 × 109/L. V.PURPOSE The second edition of the artificial intelligence (AI) data challenge was organized by the French Society of Radiology with the aim to (i), work on relevant public health issues; (ii), build large, multicentre, high quality databases; and (iii), include three-dimensional (3D) information and prognostic questions. MATERIALS AND METHODS Relevant clinical questions were proposed by French subspecialty colleges of radiology. Their feasibility was assessed by experts in the field of AI. A dedicated platform was set up for inclusion centers to safely upload their anonymized examinations in compliance with general data protection regulation. The quality of the database was checked by experts weekly with annotations performed by radiologists. Multidisciplinary teams competed between September 11th and October 13th 2019. RESULTS Three questions were selected using different imaging and evaluation modalities, including pulmonary nodule detection and classification from 3D computed tomography (CT), prediction of expanded disability status scale in multiple sclerosis using 3D magnetic resonance imaging (MRI) and segmentation of muscular surface for sarcopenia estimation from two-dimensional CT. A total of 4347 examinations were gathered of which only 6% were excluded. Three independent databases from 24 individual centers were created. A total of 143 participants were split into 20 multidisciplinary teams. CONCLUSION Three data challenges with over 1200 general data protection regulation compliant CT or MRI examinations each were organized. Future challenges should be made with more complex situations combining histopathological or genetic information to resemble real life situations faced by radiologists in routine practice. PURPOSE To prospectively compare the diagnostic capabilities of computed tomography angiography (CTA) to those of digital subtraction angiography (DSA) in endurance athletes with suspicion of arterial endofibrosis. MATERIALS AND METHODS Forty-five athletes (39 men, 6 women; median age 30 years, interquartile range 23-42 years) prospectively underwent DSA and CTA without (n=5) or with (n=40) electrocardiogram gating. DSA was interpreted by a single expert (experience of 15 years). CTA was independently interpreted by three other readers (experience of 5-8 years). Readers assessed the presence and degree of stenoses on iliac and femoral arteries and the overall diagnosis (negative, uncertain, positive) of endofibrosis at the limb level. selleck compound Sensitivities and specificities of DSA and CTA were estimated at the limb level using histological findings and long-term follow-up as reference, and compared using the McNemar test. RESULTS For diagnosing and quantifying stenoses, concordance between DSA and CTA was moderate-to-good for common and external iliac arteries, moderate for lateral circumflex arteries and poor-to-moderate for the other branches of the deep femoral artery. It was good for all readers for the overall diagnosis of endofibrosis. After long-term follow-up (median, 95 months; interquartile range 7-109 months), DSA sensitivity and specificity were respectively 88.6% (39/44; 95% confidence interval [CI] 76-95%) and 75% (24/32; 95% CI 57.9-86.7%); CTA sensitivity and specificity were respectively 88.6% (39/44; 95% CI 76-95%; P>0.99) and 84.4% (27/32; 95% CI 68.2-93.1%; P=0.51), 86.3% (38/44; 95% CI 73.3-93.6%; P>0.99) and 75% (24/32; 95% CI 57.9-86.7%; P>0.99), and 84.1% (37/44; 95% CI 70.6-92.1%; P=0.68) and 75% (24/32; 95% CI 57.9-86.7%; P>0.99) for the three readers. CONCLUSION CTA shows performances similar to those of DSA in predicting the long-term diagnosis of endofibrosis in endurance athletes with suggestive symptoms.
