Anal cancer is uncommon neoplasm with an incidence of 2 new cases per 100,000 per year in the USA, accounting approximately 0.4 % of all tumors and 2.5 % of gastrointestinal malignancies. An early detection of the anal cancer is crucial for the patient management, whereas the diagnosis at an early stage allows conservative management with sphincter sparing, on the contrary a delays in diagnosis might lead to an advance cancer stage at presentation with worst survival. According to National Comprehensive Cancer Network (NCCN) Anal Carcinoma guidelines the patients should be subjected to a careful clinical examination, including a digital rectal examination (DRE), an anoscopic examination, and palpation of inguinal nodes...

The bacterium Aeromonas salmonicida subsp. salmonicida is a common pathogen in fish farms worldwide. Since the antibiotic resistance of this bacterial species is on the increase, it is important to have a broader view on this issue. In the present study, we tested the presence of known plasmids conferring multi-drug resistance as well as antibiotic resistance genes by a PCR approach in 100 Canadian A. salmonicida subsp. salmonicida isolates. Our study highlighted the dominance of the conjugative pSN254b plasmid, which confers multi-drug resistance...

High-resolution mass spectrometry (HRMS) is widely used for the drug screening of biological samples in clinical and forensic laboratories. With the continuous addition of new psychoactive substances (NPS), keeping such methods updated is challenging. HRMS allows for combined targeted and non-targeted screening; first, peaks are identified by software algorithms, and identifications are based on reference standard data. Remaining unknown peaks are attempted identified with in silico and literature data. However, several thousand peaks remain where most are unidentifiable or uninteresting in drug screening...

New definitions of sepsis and septic shock were published in early 2016, updating old definitions that have not been revisited since 2001. These new definitions should profoundly affect sepsis research. In addition, these paper present clinical criteria for identifying infected patients who are highly likely to have or to develop sepsis or septic shock. In contrast to previous approaches, these new clinical criteria are evidence based. In this review, two of the authors of the new definitions detail the content of the papers and explore the implications for shock and sepsis researchers...

PURPOSE OF REVIEW: The purpose of this review is to provide an update of recent advances in the established role of different layers of epigenetic control mechanism that are used by joint cells to ensure tissue homeostasis and cope with changing microenvironment (e.g. ageing or disease). RECENT FINDINGS: New studies have further strengthened the evidence that joint tissue cells highly dependent on epigenetic control mechanisms, such as methylation at CpG-sites, noncoding RNAs and histone modifications to assure phenotypic plasticity and respective tissue homeostasis...

A continuous peripheral nerve block (CPNB) consists of a percutaneously inserted catheter with its tip adjacent to a target nerve/plexus through which local anesthetic may be administered, providing a prolonged block that may be titrated to the desired effect. In the decades after its first report in 1946, a plethora of data relating to CPNB was published, much of which was examined in a 2011 Anesthesia & Analgesia article. The current update is an evidence-based review of the CPNB literature published in the interim...

The ethylene-forming enzyme (EFE) from Pseudomonas syringae pv. phaseolicola PK2 is a member of the mononuclear non-heme Fe(II)- and 2-oxoglutarate (2OG)-dependent oxygenase superfamily. This enzyme is reported to simultaneously catalyze the conversion of 2OG into ethylene plus three CO2 and the Cδ hydroxylation of L-arginine (L-Arg) while oxidatively decarboxylating 2OG to form succinate and carbon dioxide. A new plasmid construct for expression in recombinant Escherichia coli cells allowed for the purification of large amounts of EFE with greater activity than previously recorded...

PURPOSE OF REVIEW: Takayasu arteritis has long been considered as an uncommon disease, rather specific to the Far-East; however recent surveys show that the disease can be seen in all ethnicities around the world with increasing prevalence rates. Nowadays, it would not be fair to consider Takayasu arteritis as a rare disease. RECENT FINDINGS: Although involvement of the thoracic aorta and its branches was more common among females, males had a tendency toward limited involvement of the abdominal aorta and its branches...

BACKGROUND: This review is an update of a previously published review in the Cochrane Database of Systematic Reviews Issue 1, 2013 on Neuromuscular electrical stimulation for muscle weakness in adults with advanced disease.Patients with advanced progressive disease often experience muscle weakness, which can impact adversely on their ability to be independent and their quality of life. In those patients who are unable or unwilling to undertake whole-body exercise, neuromuscular electrical stimulation (NMES) may be an alternative treatment to enhance lower limb muscle strength...

Lamiaceae, the sixth largest angiosperm family, contains more than 7000 species distributed all over the world. However, although considerable progress has been made in the last two decades, its phylogenetic backbone has never been well resolved. In the present study, a large-scale phylogenetic reconstruction of Lamiaceae using chloroplast sequences was carried out with the most comprehensive sampling of the family to date (288 species in 191 genera, representing approximately 78% of the genera of Lamiaceae)...

Since the last World Health Organization (WHO) Classification scheme for tumours of the urinary tract and male genital organs, there have been a number of advances in the understanding, classification, immunohistochemistry, and genetics of testicular germ cell tumours. The updated 2016 draft classification was discussed at an International Society of Urological Pathology (ISUP) Consultation on Testicular and Penile Cancer. This review addresses the main updates to germ cell tumour classification. Major changes include a pathogenetically derived classification using germ cell neoplasia in situ (GCNIS) as a new name for the precursor lesion, as well as distinction of prepubertal (non-GCNIS-derived) from postpubertal-type tumours (GCNIS-derived), acknowledging the existence of rare benign prepubertal-type teratomas in the postpubertal testis...

BACKGROUND: Caesarean sections (CS) are the most frequent major surgery in the world. A transient impairment of bowel motility is expected after CS. Although this usually resolves spontaneously within a few days, it can cause considerable discomfort, require symptomatic medication and delay hospital discharge, thus increasing costs. Chewing gum in the immediate postoperative period is a simple intervention that may be effective in enhancing recovery of bowel function in other types of abdominal surgeries...

Sepsis is a heterogeneous disease caused by an infection stimulus that triggers several complex local and systemic immuno-inflammatory reactions, which results in multiple organ dysfunction and significant morbidity and mortality. The diagnosis of sepsis is challenging because there is no gold standard for diagnosis. As a result, the clinical diagnosis of sepsis is ever changing to meet the clinical and research requirements. Moreover, although there are many novel biomarkers and screening tools for predicting the risk of sepsis, the diagnostic performance and effectiveness of these measures are less than satisfactory, and there is insufficient evidence to recommend clinical use of these new techniques...

A growing body of evidence points to CodY, a global regulator in Gram-positive bacteria, as a critical link between microbial physiology and pathogenesis in diverse environments. Recent studies uncovering graded regulation of CodY gene targets reflect the true nature of this transcription factor controlled by ligands and reveal nutrient availability as a potentially critical factor in modulating pathogenesis. This review will serve to update the status of the field and raise new questions to be answered.

BACKGROUND: In 2014, we published a series of articles in the Journal of Vascular Surgery that detailed the decrease in volume of open aneurysm repair (OAR) completed for abdominal aortic aneurysm (AAA) by vascular surgery trainees. At that time, only data points from 2000 through 2011 were available, and reliable predictions could only be made through 2015. Lack of data on endovascular aneurysm repair (EVAR) using fenestrated (FEVAR) and branched (BrEVAR) endografts also affected our findings...

A new axinid monogenean species, Axinoides euzeti n. sp. from the gills of the Mediterranean needlefish Tylosurus acus imperialis (Rafinesque) off the Tunisian coast is described. The new species is most similar in general morphology to A. meservei Price, 1946 from Tylosurus crocodilus fodiator Jordan & Gilbert off the Atlantic Ocean and to A. kola Unnithan, 1957 from Ablennes hians (Valenciennes) off the Indian Ocean. It can be differentiated from A. meservei by the shape of anterior male genital complex armed with several rows of curved spines on the cirrus rather than 3 to 4 rows of slender spines, in having a fewer testes (87-94 vs more than 100 in the drawing of A...
