7% in patients with obstructive and nonobstructive CAV, respectively (p less then .05), resulting in an odds ratio for MACE of 6 (95% CI, 1.7-21.2). Comparison of event-free survival showed a hazard ratio (HR) of 5 (95% CI, 1.95-13; p =. 004) for patients with obstructive disease. The presence of four or more stenotic coronary segments (SIS ≥ 4) was associated with a higher rate of events (HR, 3.46; 95% CI, 1.46-8.23). CONCLUSION. In patients who have undergone a heart transplant, CCTA offers a significant long-term prognostic impact on the prediction of MACEs.OBJECTIVE. The purpose of our study was to assess the feasibility of 2D shear wave ultrasound elastography to quantitatively measure changes of rigor mortis. SUBJECTS AND METHODS. Muscle stiffness of two live pigs and nine sacrificed pigs was measured in kilopascals using ultrasound elastography. The nine sacrificed pigs were divided into three groups of three pigs each and placed in one of three environments at 90°F (32°C), 70°F (21°C), or 34°F (1°C). Ultrasound elastography of five muscles was performed at 1- to 2-hour intervals for up to 50 hours postmortem. For each pig and muscle location, the time to start, peak intensity, duration of peak, and time to decline of rigor mortis were identified from the graphs of muscle stiffness values over time. These outcome variables were then compared across ambient temperature, body weight, and age groups using the Wilcoxon rank sum test. RESULTS. Postmortem measurements show a rise, peak, and decline of muscle stiffness after death. LW 6 Rigor mortis was highly significantly affected by ambient temperature (p .50). Peak intensity of rigor mortis developed more quickly but attained lower levels of muscle stiffness at 90°F (80-100 kPa) compared with 70°F and 34°F (280-300 kPa) (p less then .001). The duration of peak rigor mortis and the time to decline of rigor mortis were significantly longer for the lower temperatures (p less then .001). CONCLUSION. Two-dimensional shear wave ultrasound elastography can quantifi-ably measure the trajectory of rigor mortis in an animal model. This new approach may have direct implications for human forensic investigations.We report 23 women with axillary adenopathy on breast imaging after recent coronavirus disease (COVID-19) vaccination. A total of 13% were symptomatic (axillary lump), 43% were undergoing screening; and 43% undergoing diagnostic imaging for other reasons. BI-RADS 2 was assigned in one woman, BI-RADS 3 in 21 (ultrasound in 4-24 weeks), and BI-RADS 4 in one. Radiologist familiarity and evidence-based guidelines are needed to avoid follow-up imaging and biopsies for reactive adenopathy after COVID-19 vaccination.The identification and diagnosis of attention-deficit/hyperactivity disorder (ADHD) is extremely important in order to help change the trajectory of an individual's life outcomes. A review of the current state of evidence-based assessment of ADHD is dominated by the DSM-5's conceptualization of behaviorally-oriented diagnostic criteria. This assumption that the DSM-5's method for identifying ADHD is the gold standard underlies the research base that evaluates the incremental validity of measures and methods for diagnosing it. That is, when evaluating whether a measure is useful in the identification of ADHD, the 'right answer' is based on the DSM-5's behaviorally-oriented definition. An alternative model for considering the fact that ADHD is a neurodevelopmental disorder, with its roots in executive dysfunction, is proposed. Using neuropsychological and cognitive tests to identify executive functioning problems can be combined with rating scales and interviews to diagnose ADHD in a way that does not ascribe entirely to a behavioral definition of the disorder.Pediatric presentations of factitious disorder (Munchausen syndrome) remain underdiagnosed and poorly understood compared to adult cases. The purpose of this study is to review the current literature on child and adolescent factitious disorder in order to better understand the differences between pediatric and adult presentations of this disorder. We also present the case of an adolescent girl with factitious disorder; her hospital course draws attention to the excessive healthcare expenditures and risk of iatrogenic complications associated with this diagnosis. We utilized MEDLINE and Google Scholar databases to conduct our review. Despite the limited number of high-quality studies analyzing pediatric presentations of factitious disorder, our review yielded several important findings. Studies suggest that the general acceptance of somatization as a common way for young people to manifest emotional stress may explain the under-diagnosis of this disorder in pediatric populations. Studies also highlighted differences in the clinical characteristics of factitious disorder when patients are stratified by age; most notably, younger patients are more willing to admit intentional falsifications when confronted and more likely to accept treatment, making them a potentially more effective target for intervention.Background Despite its clinical significance, the risk of severe infection requiring hospitalization among outpatients with severe acute respiratory syndrome coronavirus 2 infection who receive angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) remains uncertain. Methods and Results In a propensity score-matched outpatient cohort (January-May 2020) of 2263 Medicare Advantage and commercially insured individuals with hypertension and a positive outpatient SARS-CoV-2, we determined the association of ACE inhibitors and ARBs with COVID-19 hospitalization. In a concurrent inpatient cohort of 7933 hospitalized with COVID-19, we tested their association with in-hospital mortality. The robustness of the observations was assessed in a contemporary cohort (May-August). In the outpatient study, neither ACE inhibitors (hazard ratio [HR], 0.77; 0.53-1.13, P=0.18) nor ARBs (HR, 0.88; 0.61-1.26, P=0.48) were associated with hospitalization risk. ACE inhibitors were associated with lower hospitalization risk in the older Medicare group (HR, 0.
