0 to 0.988. Conclusion Increased axillary lymph node or ipsilateral deltoid uptake is occasionally observed on FDG or 11C-choline PET performed after Pfizer-BioNTech or Moderna COVID-19 vaccination. Clinical impact Interpreting physicians should recognize characteristics of abnormal uptake on PET after COVID-19 vaccination to guide optimal follow-up management and reduce unnecessary biopsies.Background Hemoptysis is common following percutaneous image-guided cryoablation of pulmonary tumors. Objective To evaluate the effect of a final active thaw on the incidence, grade, and onset of hemoptysis following percutaneous cryoablation of pulmonary tumors. https://www.selleckchem.com/products/ptc596.html Methods This retrospective cohort study included 60 consecutive CT-guided cryoablation sessions targeting 95 pulmonary tumors in 47 patients from 2017 to 2020. The final thaw of a triple-freeze protocol was active (electrical, helium-free) in 27/60 sessions (45%, active group) and passive in 33/60 sessions (55%, passive group). Incidence, onset, and management of hemoptysis were recorded using prospectively collected data. Hemoptysis, pneumothorax, and hemothorax within 30 days post ablation were graded per Common Terminology Criteria for Adverse Events version 5.0 (CTCAE). Volume of immediate post-treatment changes on CT was quantified using semi-automated segmentation. Outcomes were compared between groups using generalized estimating equation modece and grade of hemoptysis and delays the onset of hemoptysis following percutaneous cryoablation of pulmonary tumors without adversely affecting other procedural complications and local tumor control. Clinical Impact Active thaw following the final freeze improves the safety profile of triple-freeze cryoablation of pulmonary tumors by reducing the incidence and grade of hemoptysis and by delaying the onset of hemoptysis beyond the immediate recovery period.Background Despite numerous published studies, management of benign papillomas without atypia remains controversial. Objective To determine the malignancy upgrade rate of benign papillomas, identify risk factors for upgrade, and formulate criteria for selective surgery. Methods This retrospective study included benign papillomas without atypia diagnosed on percutaneous biopsy between 12/01/2000 and 12/31/2019. Papillomas that did not undergo surgical excision or at least 2 years of imaging and/or clinical follow-up were excluded. Clinical, imaging, and histopathologic features were extracted from the electronic medical record. Features associated with upgrade to malignancy were identified. Multivariable logistic regression was performed. Results The study included 612 benign papillomas in 543 women (mean age 54.5 ± 12.1 years); 466 papillomas were excised, and 146 underwent imaging/clinical surveillance. The upgrade rate to malignancy was 2.3% (14/612). Upgrade rate was associated (p less then .05) with radio, while identifying all 14 upgraded lesions. Conclusion Benign non-atypical papillomas have a low malignancy upgrade rate; routine surgical excision may not be necessary. Selective excision is recommended for lesions satisfying any of the 5 criteria. Incidental papillomas or papillomas completely excised on histopathology may undergo imaging follow-up. Clinical Impact The proposed criteria for selective surgery of benign papillomas on core biopsy would reduce surgeries without delaying diagnosis of malignancy.Background Extension of type A aortic dissection (TAAD) from the sinus of Valsalva (SV) into the coronary arteries is associated with worse prognosis and requires direct coronary repair or coronary artery bypass graft (CABG) depending on extent of involvement. Objectives To assess the diagnostic performance of ECG-gated aortic CTA for detection and classification of coronary artery involvement in patients with TAAD involving the SV, using surgical findings as reference. Methods This retrospective study included 112 patients who underwent preoperative ECG-gated aortic CTA demonstrating TAAD with SV involvement. Two radiologists independently reviewed CTA images for right coronary artery (RCA) and left coronary artery (LCA) involvement. Involvement was classified using a previously described system as type A (coronary ostial dissection), B (dissection with coronary false channel), or C (complete detachment from aortic root with dissection encircling the coronary artery). Diagnostic performance of CTA was calculV involvement alone (55.7%-63.6%), coronary artery repair for types A and B (53.3%-87.5%), and CABG for type C (86.7%). Conclusions ECG-gated CTA has high diagnostic performance for detecting and classifying coronary involvement from TAAD with SV involvement. Clinical Impact CTA findings may help guide presurgical planning in these patients.You are consulted regarding an 83-year-old healthy woman who underwent renal protocol CT for a 3.6 cm renal mass. The CT was degraded by motion artifact but showed indeterminate (17 HU) enhancement in the mass, reported as suspicious for papillary renal cell carcinoma. What do you recommend for further management?

food intake records are a useful resource for diet assessment, as well as for self-evaluation, self-control, and self-motivation to change an eating behavior. New technologies based on mobile phones permit a different way of recording food intake.

to validate and assess food photographic record (FPR) as a useful instrument in professional practice for assessing food intake.

forty nutrition professionals participated. In a first stage, food variables obtained through FPR were analyzed and correlated with data from the frequency of food consumption questionnaire (FFQ) and a 24-hour recall (24HR). In a second stage, FPR was applied again to evaluate temporal stability (FPR 1 versus FPR 2). Wilcoxon's test and Spearman's correlation test were applied.

a moderate and significant positive association was found for total caloric intake (TCI) and total fat between FPR and 24HR (r = 0.68, p = 0.0008, and r = 0.52, p = 0.01, respectively). In addition, a positive and moderate association was found for TCI, proteins and fats between FPR 1 and FPR 2 (r = 0.61, p = 0.0004; r = 0.60, p = 0.0005; r = 0.64, p = 0.0002, respectively).

FPR is a valid method for professional practice to estimate dietary intake, with greater consistency with 24HR data than FFQ, and presents temporal stability for TCI, protein and fat recordings. In addition, FPR may facilitate the adoption of positive eating habits such as more conscious intakes, among other benefits.
