INTRODUCTION: Gallstones are known to be associated with premalignant changes in the gallbladder epithelium that range from atypical hyperplasia, metaplasia, dysplasia to carcinoma. Recognition of factors associated with these changes in patients with gallstones can potentially be helpful in identifying patients to whom prophylactic cholecystectomy can be offered to reduce the chances of developing carcinoma. OBJECTIVE: To identify factors associated with premalignant epithelial changes including atypical hyperplasia, metaplasia, and dysplasia in gallbladder mucosa in patients with chronic calculus cholecystitis...

OBJECTIVES: Studies of hunter-gatherer oral pathology, particularly in Australia, often focus upon dental wear and caries or assume that historic studies of Aboriginal people reflect the precontact past. Consequently the range of population variation has been underestimated. In this paper dental pathology from human remains from Roonka are compared with a model of dental pathology derived from historic studies. The aim is to identify aspects of dental pathology indicative of regional or intra-population diversity...

INTRODUCTION: Since the beginning of the use of sialendoscopy and extra-corporeal lithotripsy, recommendations have changed. The purpose of this retrospective study was to evaluate the efficiency of our treatment protocol, without a lithotripter, under general anaesthesia in the Stomatology and Maxillofacial Surgery Department of Lille University Hospital. The secondary goals were to evaluate patient tolerance and satisfaction. MATERIALS AND METHODS: All patients treated with sialendoscopy alone, sialendoscopy with a combined surgical approach or a transoral approach (TOA) (sialolithotomy) between January 2013 and December 2015 were included...

Cases: Septic cardiomyopathy is defined as a reversible left ventricular systolic dysfunction. Patients with severe septic cardiomyopathy have a high mortality rate, even if they receive conventional therapy. For those patients, previous reports showed intra-aortic balloon pump (IABP) efficacy. We report two rare cases with IABP introduction leading them to drastic improvement, and survival from severe septic cardiomyopathy. Case 1 is a 78-year-old woman diagnosed with renal calculus pyelonephritis, septic shock, and septic cardiomyopathy...

In this personal essay, the author reflects on experiences in global health professions education projects, and the moral reasoning that might be required to define explicitly what constitutes ethical participation. Three interrelated notions are explored: The decision to engage or not through a discussion of the concepts of safety, understanding power dynamics, and analysis of personal and institutional motivations for the projectThe ultimate goals to promote human flourishing and improve equity, through attention to local inequities potentially experienced by either participants or colleagues from home...

Proteomic analysis of dental calculus is emerging as a powerful tool for disease and dietary characterisation of archaeological populations. To better understand the variability in protein results from dental calculus, we analysed 21 samples from three Roman-period populations to compare: 1) the quantity of extracted protein; 2) the number of mass spectral queries; and 3) the number of peptide spectral matches and protein identifications. We found little correlation between the quantity of calculus analysed and total protein identifications, as well as no systematic trends between site location and protein preservation...

Calculating the evolution of polarization for all polarization states of light in optical systems, in global coordinates, is an important, yet challenging task. This calculation exists for completely polarized light, but has not yet been developed for partially polarized light. A 3 × 3 coherency matrix for partially polarized light, in global coordinates, is presented to calculate the transformation of its polarization as it passes through an optical system. This matrix is a three-dimensional generalization of the coherency matrix...

Background: An intrauterine device is commonly used for contraception globally. Although intrauterine device placement is an effective and safe method of contraception, migration into the bladder with stone formation is a rare and serious complication. The management approaches for an intrauterine device embedded in the bladder include endoscopic procedures and open surgical removal. In this study, we report the case of a patient with recurrent urinary tract infection associated with intrauterine device migration and urolithiasis, who successfully underwent endoscopic treatment combined with laser fragmentation...

Haide Gou, Baolin Li
In this paper, we deal with a class of nonlinear fractional nonautonomous evolution equations with delay by using Hilfer fractional derivative, which generalizes the famous Riemann-Liouville fractional derivative. The definition of mild solutions for the studied problem was given based on an operator family generated by the operator pair [Formula: see text] and probability density function. Combining the techniques of fractional calculus, measure of noncompactness, and fixed point theorem with respect to k-set-contractive, we obtain a new existence result of mild solutions...

Itsuro Kazama, Toshiyuki Nakajima
RATIONALE: In patients with bilateral ureteral obstruction, the serum creatinine levels are often elevated, sometimes causing postrenal acute kidney injury (AKI). In contrast, those with unilateral ureteral obstruction present normal serum creatinine levels, as long as their contralateral kidneys are preserved intact. However, the unilateral obstruction of the ureter could affect the renal function, as it humorally influences the renal hemodynamics. PATIENT CONCERNS: A 66-year-old man with a past medical history of hypertension and diabetes mellitus came to our outpatient clinic because of right abdominal dullness...

In her reply to my critical assessment of objections to the Weatherall report's justification of non-human primate (NHP) research, Catia Faria focuses on three objections which she entitles 'the disanalogy', 'the utilitarian calculus' and 'species overlap'. Faria finds my assessment unconvincing, butI argue that the objections still fail.

Despite overwhelming basic science linking inflammation to the pathobiology of atherothrombosis, the specific clinical evidence indicating cardiovascular benefits from anti-inflammatory pharmacotherapy has been lacking. The CANTOS trial (Ridker et al., 2017a) now provides the first largescale proof of concept that inflammasome targeting can reduce cardiovascular events-and, surprisingly, lung cancer.

REVIEW
P Johnson, J Moriarty, G Peskir
The real-time detection of changes in a noisily observed signal is an important problem in applied science and engineering. The study of parametric optimal detection theory began in the 1930s, motivated by applications in production and defence. Today this theory, which aims to minimize a given measure of detection delay under accuracy constraints, finds applications in domains including radar, sonar, seismic activity, global positioning, psychological testing, quality control, communications and power systems engineering...
