  Air and surface contamination with viral RNA was relatively low in these healthcare settings after the enhancement of infection prevention and control. Environmental contamination could still be found near seroconverted patients, suggesting the need to maintain constant vigilance in healthcare settings to reduce healthcare-associated infection during the COVID-19 pandemic.

  The European Society of Cardiology (ESC) recommends a 0-h/1-h (0/1-h) algorithm to classify patients with suspected non-ST-segment elevation myocardial infarction (NSTEMI). However, reliable evidence about patients who present early after the onset of symptoms is limited, likely because high-sensitivity cardiac troponin (hs-cTn) values cannot increase sufficiently within that time. This study aimed to evaluate the outcomes in real-world situations that utilized the 0/1-h algorithm.
 
  In a prospective, international, multicenter cohort study that enrolled 1638 patients presenting with acute chest pain to the emergency department, we assessed the performance of the 0/1-h algorithm using hs-cTnT and the associated 30-day rates of major adverse cardiac events death and acute myocardial infarction (AMI).
 
  Among 1074 patients, the prevalence of AMI was 16.0%. An approximately 60.1% (n=645) of patients visited the hospital within 3h after onset of chest pain (less than 1h; 18.2% [n=196], less than 2h; 27.5% [n=295], and less than 3h; 14.3% [n=154]). Moreover, the prevalence rates of AMI were similar at all times (1h, 16.8%; 1-2h, 20.7%; 2-3h, 18.2%; p=.5). According to the ESC 0/1-h algorithm, the distribution patterns of rule-out, observe, and rule-in groups were similar; however, none of the patients was diagnosed with AMI or cardiac death in the rule-out group.
 
  This study revealed the applicability of the 0/1-h algorithm for the management of early presenters.

  The histopathological diagnosis of cardiac sarcoidosis (CS) is challenging because of sampling error in endomyocardial biopsy (EMB) and the determinants of positive EMB are unclear. Reduced left ventricular ejection fraction (LVEF) is a simple parameter of the extent of myocardial damage, and higher serum angiotensin-converting enzyme (ACE) activity would indicate the spread of disease activity in CS patients. Thus, we sought to examine whether these parameters are related to the histopathological diagnosis of CS by EMB.
 
  A total of 94 consecutive clinically diagnosed CS patients between August 1986 and March 2019 who were admitted to two academic hospitals were examined. We determined EMB as positive if non-caseating epithelioid granulomas were confirmed in the myocardial tissue. Patients were divided into two groups according to positive (n=37) and negative (n=57) EMB. We assessed the relationship between LVEF, serum ACE activity and positive EMB.
 
  Multivariable analysis revealed that both LVEF and serum ACE were independently associated with positive EMB (OR 0.83, 95% CI 0.70-0.99; OR 1.39, 95% CI 1.02-1.90, respectively). Moreover, patients with both lower LVEF (<37%, median) and higher ACE activity (≥13.5IU/L, median) had the highest frequency of positive EMB (p=.003). The combination of lower LVEF and higher serum ACE showed better specificity (91.2%) and positive predictive value (73.7%) than either LVEF or serum ACE alone for positive EMB.
 
  Lower LVEF and higher serum ACE activity were associated with positive EMB, suggesting that these parameters might be useful for predicting positive EMB in CS patients.

  Cold snare defect protrusions (CSDPs) include muscularis mucosa (MM) and submucosa tissue. CSDPs are thought to result from fragmentation of the specimen during shallow excision. Our aim in this study was to clarify whether CSDPs are associated with polyp fragmentation.
 
  We retrospectively analyzed 1026 neoplastic colorectal polyps resected by cold snare polypectomy for which the presence or absence of CSDPs was assessed from the endoscopic image. All prepared specimens were reviewed and assessed for the presence or absence of polyp fragmentation, and the proportion of MM on the stump was measured.  https://www.selleckchem.com/products/CP-690550.html  In addition, the risk factors for CSDP occurrence were evaluated.
 
  CSDPs occurred in 116 of the 1026 polyps (11.3%).  https://www.selleckchem.com/products/CP-690550.html  Polyp fragmentation was significantly associated with the occurrence of CSDP on univariate analysis (odds ratio [OR], 3.74; P< .001) and multivariate analysis (OR, 3.13; P< .001). The proportion of MM >50% was significantly lower in the CSDP group than in the non-CSDP group (51.5% vs 70.9%, P< .001). CSDPs were significantly associated with a large polyp size (OR, 1.32; P= .007) and a large specimen size (OR, 1.24; P< .001) on multivariate analysis.
 
  The occurrence of CSDP was associated with less MM on the stump and fragmentation of the specimen. Clinically, the presence of CSDP is a good indicator of polyp fragmentation.

Histone acetylation is involved in the extinction of fear memory. As the "readers" of histone acetylation markers, the role of the bromodomain and extraterminal domain (BET) proteins in fear extinction is still unclear. In the present study, we found that suppression of BET proteins using small molecule JQ-1 had no effects on the acquisition of auditory fear or on the extinction of recent auditory fear, but it impaired the extinction of remote auditory fear. We found that insulin like growth factor 2 (IGF-2) mRNA and protein were up-regulated in the anterior cingulate cortex (ACC) after the extinction training of remote fear memory, and that this effect was inhibited by JQ-1 administration. Further, the local delivery of IGF-2 protein to the ACC region rescued the impaired extinction of remote memory caused by JQ-1 administration, which suggesting IGF-2 mediates the effects of JQ-1 on remote memory extinction.
