V.The vision for the Journal of Cardiovascular Computed Tomography's social media efforts is to amplify the impact of the Journal while driving engagement, increasing journal visibility and disseminating content to new audiences globally. Serving as "the front door" to the Journal, this digital evolution represents an important step forward for a field in which advancements in hardware, image processing and clinical evidence have evolved rapidly. However, is social media the panem et circenses of cardiovascular computed tomography (CT), that of superficial appeasement, or of sine qua non; an essential ingredient to the acceleration of the Journal and of the field of cardiovascular CT? This paper aims to present the initial impact of social media within a dedicated cardiovascular CT journal. PURPOSE Peri-coronary adipose tissue attenuation expressed by fat attenuation index (FAI) on coronary CT angiography (CCTA) reflects peri-coronary inflammation and is associated with cardiac mortality. We aimed to investigate the association between FAI and whole vessel and lesion plaque quantification on CCTA in stable patients with intermediate epicardial stenosis evaluated by fractional flow reserve (FFR). METHODS A total of 187 left anterior descending arteries (LAD) with intermediate stenosis who underwent FFR measurement and CCTA were studied. FAI was assessed by the crude analysis of the mean CT attenuation value of LAD on CCTA. Determinants of FAI and FFR were explored. Furthermore, the impact of combined baseline data, CCTA-derived lesion plaque assessment, whole vessel quantification, cardiac mass and FAI on discrimination efficacy for ischemia was evaluated as FFR used for a reference standard. RESULTS The mean FAI and the median FFR values were -73.0 and 0.77, respectively. Multivariate analysis revealed that male, CCTA-derived positive remodeling, lower minimum lumen area, higher target vessel total cardiac mass, and lower FFR were independent predictors of FAI. CCTA-derived two-dimensional and three-dimensional analysis and FAI were independently and significantly associated with FFR values. Net reclassification index and integrated discrimination improvement index were both significantly improved when FAI was added to the baseline model for lesions with FFR less then 0.75, but not for FFR≤0.80. CONCLUSIONS FAI was associated with FFR, CCTA-derived two-dimensional and three-dimensional lumen and plaque quantification and cardiac mass in patients with intermediate lesions in LAD, indicating that comprehensive CTA assessment may provide risk-stratification. BACKGROUND Dobutamine stress echocardiography (DSE) and coronary computed tomography angiography (CTA) can provide perioperative prognostic information in risk stratification of patients undergoing noncardiac surgery. This study directly compared the prognostic value of DSE and CTA in patients undergoing noncardiac surgery. METHODS Between 2014 and 2016, 215 patients with more than one clinical risk factor for perioperative cardiovascular (CV) events were enrolled prospectively. They received both DSE and CTA before noncardiac surgery. Perioperative clinical risk was classified according to the revised cardiac risk index (RCRI), DSE results were categorized as abnormal (inducible ischemia and/or nonviable infarction) or not. Bafilomycin A1 mouse CTA results were assessed using the severity of stenosis, with significant stenosis being ≥50% of the luminal diameter). After the exclusion, a total of 206 patients remained. Perioperative CV events were defined as CV death, non-fatal myocardial infarction (MI), myocardial injury, pulmonary edema, non-fatal stroke, and systemic embolism within 30 days after surgery. RESULTS Twenty-four patients (12%) had perioperative cardiac events (1 cardiac death, 10 non-fatal MI, 8 myocardial injury, 11 pulmonary edema, 1 non-fatal stroke, and 1 pulmonary embolism). Following adjustment for baseline RCRI score, abnormal result on DSE (OR, 6.08, 95% CI, 2.41 to 15.31, P  less then  0.001), significant CAD on CTA (OR, 18.79; 95% CI, 5.24 to 67.42, P  less then  0.001), and high CACS (OR, 4.19; 95% CI, 1.39 to 12.60, P = 0.011) remained significant predictors of perioperative CV events. CONCLUSIONS DSE and CTA are independent predictive factors of events in patients undergoing noncardiac surgery. Among them, assessment of significant CAD using CTA might show a higher prognostic value compared with DSE before noncardiac surgery. CLINICAL TRIAL REGISTRATION URL http//www.clinicaltrials.gov. Unique identifier NCT02250963. The fetal immune system develops in a rather sterile environment relative to the outside world and, therefore, lacks antigenic education. Soon after birth, the newborn is exposed to the hostile environment of pathogens. Recently, animal- and limited human-based studies have indicated that help from the mother, upon transfer of leukocytes and their products via breast milk feeding, greatly assists the newborn's immune system. Here, I discuss the newest advances on how milk leukocytes impact early life immunity, with an emphasis on the development of the infant T cell repertoire and early immune responses in the periphery and gut-associated lymphoid tissue. A deeper understanding of these novel mechanistic insights may inform potential translational approaches to improving immunity in infants. The sea snake tick (Amblyomma nitidum) is a host specialist of snakes in the genus Laticauda and is one of the few ticks which could be regarded as semi-marine. Yet despite the attention this species has received due to its bizarre ecology, its distribution remains poorly known as geographic records of its occurrence through the Asia-Pacific are highly fragmentary. For the first time this species is recorded from Taiwan based on specimens collected from the yellow-lipped sea krait (Laticauda colubrina). Candidatus Neoehrlichia mikurensis, the causative agent of tick-borne "neoehrlichiosis" has recently been reported in humans, mammals and ticks in Europe. The aim of this study was to map the distribution of this bacterium in questing ticks in the Czech Republic. A total of 13,325 Ixodes ricinus including 445 larvae, 5270 nymphs and 7610 adults were collected from vegetation by flagging in 140 Czech towns and villages from every region of the Czech Republic. The ticks were pooled into 2665 groups of 5 individuals respecting life stage or sex and tested for the presence of Ca. Neoehrlichia mikurensis by conventional PCR targeting of the groEL gene. The bacterium was detected in 533/2665 pools and 125/140 areas screened, showing an overall estimated prevalence of 4.4 % in ticks of all life stages. Phylogenetic analysis revealed only small genetic diversity among the strains found. Two pools of questing larvae tested positive, suggesting transovarial transmission. According to this study, Ca. Neoehrlichia mikurensis is another tick-borne pathogen widespread in I.
