These were 8 men and 3 women aged between 30 and 79 years (mean 62.2). Conclusions Patients with COVID-19 can present few symptoms of the disease, and in PET/CT studies both presymptomatic and almost asymptomatic patients can be detected, so nuclear medicine physicians should take special attention to the pulmonary evaluation of PET/CT studies.Background Patients with peripheral artery disease (PAD) are at high risk of cardiovascular events, including myocardial infarction (MI), stroke, and cardiovascular death. However, the impact of PAD on prognosis in Japanese patients with acute MI remains unclear. Methods The Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET) is a prospective multicenter registry that registered 3283 patients with acute MI. Among them, 2970 patients with available data of PAD were divided into the following 4 groups 2513 patients without prior MI or PAD (None group), 320 patients with only prior MI (Prior MI group), 100 patients with only PAD (PAD group), and 37 patients with both previous MI and PAD (Both group). The primary endpoint was a composite of all-cause death, non-fatal MI, non-fatal stroke, cardiac failure, and urgent revascularization for unstable angina. Results The 3-year cumulative incidence of the primary endpoint was 26.9% in None group, 41.4% in Prior MI group, 48.0% in PAD group, and 60.3% in Both group (p less then 0.001). https://www.selleckchem.com/products/azd5363.html In multivariate analysis, hazard ratio using None group as reference was 1.55 (95% confidence intervals 1.25-1.91; p less then 0.001) for MI group, 2.26 (1.61-3.07; p less then 0.001) for PAD group, and 2.52 (1.52-3.90; p less then 0.001) for Both group. Conclusions Concomitant PAD was associated with poor prognosis in Japanese patients with acute MI.Background Catheter ablation is the established treatment for patients with symptomatic Wolff-Parkinson-White syndrome (WPW). However, some patients undergo a challenging ablation or have recurrences during the early post-ablation phase. The aim of this study was to evaluate the clinical factors associated with an unsuccessful ablation outcome or repeated sessions. Methods Four hundred seventy-five symptomatic consecutive WPW patients (38.2±16.2 years old, 61% men, 69% with pre-excitation) who underwent an accessory pathway (AP) ablation from August 2005 to December 2015 were enrolled. When APs recurred, a redo ablation procedure was performed according to the patients' desire. Results Four hundred thirty-nine patients (92.4%) were cured by ablation, but it failed in 36 (7.6%) after the first procedure. Seventeen patients had AP recurrences during the acute phase within 36h post-ablation. On the other hand, 4 were identified after more than one year. In a multivariate logistic regression analysis, multiple, parahisian, and broad APs were significant independent predictors of recurrences after the 1st procedure, with odds ratios of 14.88 (p less then 0.001), 10.14 (p less then 0.001), and 6.88 (p less then 0.001), respectively. Finally, 468 patients (98.5%) received a successful ablation during a mean follow-up of 8.3±3.0 years. However, after the final procedure no significant predictors were recognized. Out of 508 total procedures, three major (0.6%) complications occurred. Conclusions Symptomatic WPW patients with multiple, parahisian, and broad APs had a significantly higher risk of recurrence. In half of the recurrence patients, AP recurrences were confirmed during the acute phase, but were rarely recorded in the very late phase.Background This study evaluated whether caffeine abstention is required before fractional flow reserve (FFR) measurement by intravenous adenosine triphosphate (ATP) administration in Japanese patients. Methods This study was a subanalysis of a previously published study and a total of 208 intermediate lesions that underwent FFR measurements were enrolled for this analysis. Hyperemia was induced by continuous intravenous ATP infusion at 150 μg/kg/min (IVATP150) and 210 μg/kg/min (IVATP210), and by intracoronary administration of nicorandil 2 mg (ICNIC2mg) as a reference standard. Results The degree of change in the FFR value after ICNIC2mg and IVATP210 was similar between the caffeine and non-caffeine groups (0.00 ± 0.02 vs. 0.01 ± 0.02). In patients who consumed caffeine before the FFR measurement, the degree of FFR change was independent of the time interval ( less then 12 h, 12-24 h, and 24-48 h) between caffeine intake and catheterization both after IVATP150 and ICNIC2mg and after IVATP210 and ICNIC2mg. Conclusion When compared with the FFR value after ICNIC2mg, the degree of change in the FFR value after IVATP210 were similar regardless of caffeine intake. Strict caffeine abstention before intravenous ATP-induced FFR measurement may not be required in clinical practice.Background Chilaiditi syndrome is a rare condition characterized by impaired fixation of the colon resulting in symptoms secondary to colonic interposition. It commonly presents with nonspecific abdominal pain and constipation, making clinical diagnosis difficult, especially in pregnancy. Case report A 29-year-old afebrile woman in the week 28 of pregnancy presented with right-sided abdominal pain and constipation. With an Alvarado score of 6, the working diagnoses were acute appendicitis and intestinal obstruction. After a normal transabdominal ultrasound, emergent abdominal magnetic resonance imaging showed abnormal fixation of hepatic flexure wedged between the falciform ligament and liver. Without clinical, laboratory, and radiologic signs of complete obstruction or colonic perforation, conservative therapy was introduced and was successful. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? Symptoms associated with Chilaiditi syndrome in pregnancy include nonspecific abdominal pain, and the correct preoperative diagnosis is difficult. The most common differential diagnoses are intestinal obstruction and acute appendicitis. It is important to diagnose Chilaiditi syndrome early because it can lead to severe complications, including intestinal obstruction, perforation, and ischemia. Therefore, in patients with right-sided abdominal pain with inconclusive transabdominal ultrasound, emergent magnetic resonance imaging leads to early diagnosis and treatment, minimizes maternal and fetal complications, avoids unnecessary explorations, and shortens the hospitalization.
