Longitudinal assessment of anchored transponder migration following lung stereotactic body radiation therapy.
CONCLUSION: No significant difference in the rates of fiducial marker retention and migration were noted when comparing patients who had anchored transponders placed into small airways and a 2:1 matched cohort of patients who had other commercially available lung fiducial markers placed. In both groups, no late or chronic toxicity appeared to be related to the implanted fiducial markers. PMID: 30387242 [PubMed - as supplied by publisher]
ConclusionsTFA was determined to be a theranostic agent for chemical ablation of solid tissue. Ablation was both efficacious and imageable in ex vivo healthy tissue, even at low concentrations or with high temporal resolution.

Patients evaluated their comfort by using an 11-point numerical rating scale (NRS-11) after completing the two examinations. The lower the score was, the more comfortable the examinat...

SummersPurposeAccurate pancreas segmentation has application in surgical planning, assessment of diabetes, and detection and analysis of pancreatic tumors. Factors that affect pancreas segmentation accuracy have not been previously reported. The purpose of this study is to identify technical and clinical factors that adversely affect the accuracy of pancreas segmentation on CT.Method and MaterialsIn this IRB and HIPAA compliant study, ...

Conclusion: The new OBQ11 satisfies the measurement criteria defined by the Rasch model. However, further studies of additional samples are needed to validate its generic properties. Significance: The purpose of the OBQ11 is to measure occupational balance of individuals or groups, and to identify aspects of occupational balance in need of improvement. Our observations suggest that the OBQ11 is a valid and promising complement to other instruments. PMID: 31524026 [PubMed - as supplied by publisher]
ConclusionWater vapor endometrial ablation preserved an accessible uterine cavity and visualization of the ostia in the majority of subjects, with minimal incidence of severe adhesions a mean of four years following the ablation procedure.
We thank Aoki et al1 for their comments on our article.2 Their comments highlight several key issues that gastroenterologists face when treating patients admitted to the hospital with GI bleeding.
We read with great interest the article by Marya et al1 reporting a randomized controlled trial (RCT) on early deployment of a video capsule for detecting the bleeding source. One current guideline suggests selecting the first endoscopy based on stool color, for both upper and lower GI bleeding.2 However, physicians cannot always detect the definit ive bleeding source at the first endoscopy in clinical practice.
I read with interest the article by Lin et al.1 The authors conducted a risk assessment to evaluate the relationship between anticoagulation or antiplatelet medications and postpolypectomy bleeding according to 2 epidemiologic study designs. In a retrospective cohort study, the authors observed 59 cases. Thereafter, the authors conducted a case-control study with 174 matched control individuals. In multivariate logistic regression analysis, the adjusted odds ratios (95% confidence interval [CI]) of heparin bridge and polyp size ≥2 cm in patients with warfarin medication were 10.27 (2.51-42.1) and 8.8 (1.28-60.7), respectively.
ConclusionsPET/CT was useful for early detection of EPCs. The use of PET/CT for the early detection and treatment of EPCs with no symptoms can improve treatment outcomes.
