Prompt discharge after laparoscopic appendectomy (LA) is a marker of quality of care, fiscally desirable and feasible in select patients. Patients over 30 comprise a more heterogeneous cohort known to experience worse outcomes after LA. We aimed to identify easily available preoperative risk factors portending a postoperative length of stay ≥2 days among patients above age 30. In this investigation, 296 included patients from a single institution who underwent LA for acute appendicitis from 2010 to 2014 were retrospectively reviewed for preoperative demographics, laboratory studies, comorbidities, presentation characteristics, radiographic finding, and other rationally selected factors for association with postoperative length of stay ≥2 days...

The data for the Ebola outbreak that occurred in 2014-2016 in three countries of West Africa are analysed within a common framework. The analysis is made using the results of an agent based Susceptible-Infected-Removed (SIR) model on a Euclidean network, where nodes at a distance l are connected with probability P(l) ∝ l(-δ), δ determining the range of the interaction, in addition to nearest neighbors. The cumulative (total) density of infected population here has the form , where the parameters depend on δ and the infection probability q...

Kevin R Brooks
The history of the expression of three-dimensional structure in art can be traced from the use of occlusion in Palaeolithic cave paintings, through the use of shadow in classical art, to the development of perspective during the Renaissance. However, the history of the use of stereoscopic techniques is controversial. Although the first undisputed stereoscopic images were presented by Wheatstone in 1838, it has been claimed that two sketches by Jacopo Chimenti da Empoli (c. 1600) can be to be fused to yield an impression of stereoscopic depth, while others suggest that Leonardo da Vinci's Mona Lisa is the world's first stereogram...

Oxidative stress and inflammation are two major contributing factors to atherosclerosis, a leading cause for cardiovascular diseases (CVDs). Oxidation of phospholipids on the surface of low density lipoprotein (LDL) particles generated under oxidative stress has been associated with the progression of atherosclerosis but the underlying molecular mechanisms remain poorly defined. We identified a novel series of oxidation products containing cyclopentenone moiety, termed deoxy-A2/J2-isoprostanes-phosphocholine (deoxy-A2/J2-IsoP-PC), from 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphocholine (PAPC) in vivo using mass spectrometry and by comparison to a chemically synthesized standard...

BACKGROUND AND AIMS: About 50% of patients admitted to the Intensive Care Unit have systemic inflammatory response syndrome (SIRS), and about 10%-20% of them died. Early risk stratification is important to reduce mortality. Plasma neutrophil gelatinase-associated lipocalin (NGAL) is increased by inflammation and infection. Its ability to predict mortality in SIRS patients is of interest. We evaluated the ability of serial measurement of NGAL for the prediction of mortality in critically ill patients with SIRS...

Lei Wang, Zhidong Teng, Tingting Tang, Zhiming Li
In this paper, the dynamical behaviors for a stochastic SIRS epidemic model with nonlinear incidence and vaccination are investigated. In the models, the disease transmission coefficient and the removal rates are all affected by noise. Some new basic properties of the models are found. Applying these properties, we establish a series of new threshold conditions on the stochastically exponential extinction, stochastic persistence, and permanence in the mean of the disease with probability one for the models...

BACKGROUND AND AIMS: Immunosuppressive therapy for inflammatory bowel disease (IBD) in pediatric patients is thought to increase risk of malignancy and lymphoproliferative disorders, including hemophagocytic lymphohistiocytosis (HLH). We compared unadjusted incidence rates and of malignancy and HLH in pediatric patients with IBD exposed to infliximab compared with patients not exposed to biologics and calculated standardized incidence ratios (SIRs). METHODS: We collected and analyzed data from 5766 participants in a prospective study of long-term outcomes of pediatric patients with IBD (NCT00606346), from 2007 through 30 June 2016...

Shear wave elastography (SWE) has been developed to non-invasively estimate liver stiffness. Different techniques are available and they are described in detail in the EFSUMB guidelines on elastography. However, there are only a few published studies investigating normal ranges in healthy subjects by comparing different equipment and analysing influencing factors. In the present review, we summarize the impact factors on liver stiffness measurement (LSM) using SWE, report its reproducibility, and define normal range tables of LSM in healthy subjects for clinical practice according to the published literature...

Heterochromatin formation in the yeast Saccharomyces cerevisiae is characterized by the assembly of the Silent Information Regulator (SIR) complex, which consists of the histone deacetylase Sir2 and the structural components Sir3 and Sir4 and binds to unmodified nucleosomes to provide gene silencing. Sir3 contains an AAA(+) ATPase-like domain, and mutations in an exposed loop on the surface of this domain abrogate Sir3 silencing function in vivo as well in vitro binding to the Sir2/ Sir4 subcomplex. Here, we found that the removal of a single methyl group in the C-terminal coiled-coil domain (mutation T1314S) of Sir4 was sufficient to restore silencing at the silent mating-type loci HMR and HML to a Sir3 version with a mutation in this loop...

BACKGROUND: Acute pancreatitis is a disease with variable outcome; the course of the disease can be modified by early aggressive management in patients with severe pancreatitis. Easily calculable pancreatic scores and investigations can help to triage these patients. We aimed to determine the role of bedside index for severity in acute pancreatitis (BISAP), harmless acute pancreatitis score (HAPS), and systemic inflammatory response syndrome (SIRS) scores on day of admission and C-reactive protein (CRP) at 48 h for predicting the presence of pancreatic fluid collection (PFC) and necrosis on CT scans done at 72 h...
