Entamoeba histolytica has been recently recognised as an emerging sexually transmissible pathogen in men who have sex with men (MSM), causing sporadic outbreaks in countries where it is not endemic. Here we report two closed clusters of invasive amoebiasis occurring in Barcelona, Spain, in October 2016 (four cases) and in January 2017 (four cases).

Survival improvement in rectal cancer treated with neoadjuvant chemoradiotherapy (nCRT) is achieved only if pathological response occurs. Mandard tumor regression grade (TRG) proved to be a valid system to measure nCRT response. The ability to predict tumor response before treatment may significantly have impact the selection of patients for nCRT in rectal cancer. The aim is to identify potential predictive pretreatment factors for Mandard response and build a clinical predictive model design. 167 patients with locally advanced rectal cancer were treated with nCRT and curative surgery...

Next generation sequencing has provided a comprehensive understanding of the mutational landscape in chronic lymphocytic leukemia (CLL), and new drivers have been identified. Some of these drivers could be pharmacologically targeted to choose the most effective personalized therapy in each CLL patient. Areas covered: In this article, the authors uncover the potential role of new targeted therapies against the most recurrent mutations in CLL as well as the recently approved therapies. The authors also provide their expert opinion and give their perspectives for the future...

REVIEW
Ann C Babtie, Michael P H Stumpf
Dynamical systems describing whole cells are on the verge of becoming a reality. But as models of reality, they are only useful if we have realistic parameters for the molecular reaction rates and cell physiological processes. There is currently no suitable framework to reliably estimate hundreds, let alone thousands, of reaction rate parameters. Here, we map out the relative weaknesses and promises of different approaches aimed at redressing this issue. While suitable procedures for estimation or inference of the whole (vast) set of parameters will, in all likelihood, remain elusive, some hope can be drawn from the fact that much of the cellular behaviour may be explained in terms of smaller sets of parameters...

PURPOSE: The purpose of this study was to evaluate the risk factors for anastomotic leakage (AL) after anterior resection for middle and low rectal cancer in order to help surgeons to decide which patients could benefit from a diverting stoma. METHODS: Data on 319 patients having a middle and low rectal cancer resection with anastomosis between May 2011 and October 2015 from two hospitals were included in the study. The analysis included the following variables: patient-related variables (gender, age, diabetes mellitus, ASA score, preoperative radiochemotherapy, body mass index, blood hemoglobin, and serum albumin level), tumor-related variables (K-ras status, distance of tumor from the anal verge, histopathologic grade, pathological T stage, pathological N stage, pathological M stage, TNM stage, and tumor size), and surgery-related variables (laparoscopic or open surgery, blood loss, and operative time)...

REVIEW
Megan E Frederickson
Mutualisms teeter on a knife-edge between conflict and cooperation, or so the conventional wisdom goes. The costs and benefits of mutualism often depend on the abiotic or biotic context in which an interaction occurs, and experimental manipulations can induce shifts in interaction outcomes from mutualism all the way to parasitism. Yet, research suggests that mutualisms rarely turn parasitic in nature. Similarly, despite the potential for 'cheating' to undermine mutualism evolution, empirical evidence for fitness conflicts between partners and, thus, selection for cheating in mutualisms is scant...

Pakistan is at the verge of polio eradication but isolation of non-polio enteroviruses (NPEVs) from acute flaccid paralysis (AFP) cases may result in serious or even fatal outcome. Many enteroviruses share similar symptoms and epidemiology as is the case with poliovirus and coxsackievirus (CV). The present study was designed to genetically characterize coxsackievirus B (CV-B) serotypes isolated from non-polio acute flaccid paralytic children, as well as to understand their probable role in paralysis. A total of 63 (20·1%) out of 313 stool samples during 2013 were found positive for NPEVs in rhabdomyosarcoma cells...

Amylosucrase from Neisseria polysaccharea naturally catalyzes the synthesis of α-1,4 glucans from sucrose. The product profile is quite polydisperse, ranging from soluble chains called maltooligosaccharides to high-molecular weight insoluble amylose. This enzyme was recently subjected to engineering of its active site to enable recognition of non-natural acceptor substrates. Libraries of variants were constructed and screened on sucrose, allowing the identification of a mutant that showed a 6-fold enhanced activity toward sucrose compared to the wild-type enzyme...

BACKGROUND: Anastomotic stricture following colorectal cancer surgery is not a rare complication, but proper management of anastomotic stricture located close to the anal verge is uncertain. This study aimed to investigate risk factors and management strategies for anastomotic stricture after ultralow anterior resection (ULAR). METHODS: We retrospectively reviewed a database of patients with rectal cancer who underwent surgery between January 2007 and June 2015, and included patients with an anastomosis within 4 cm from the anal verge...

Alterations in traditional land use practices have led to severe declines in the area of semi-natural grasslands, thereby seriously threatening plant and animal species dependent on these habitats. Small anthropogenic managed habitats, like roadsides can act as refuges and might play an important role in conserving these species. Colonization of roadside verges by endangered lizard orchids (Himantoglossum spp.) has long been known, but few studies have systematically explored the suitability of roadside habitats for these orchids and the impact of roads on them...

RATIONALE: The lower rectal gastrointestinal stromal tumor (GIST) is a rare entity and warrants special attentions because of the considerations of preserving of anal and urinal functions. Neoadjuvant therapy with imatinib mesylate (IM) has achieved great success in GIST, which potentially extends the applications of function-preserving minimally invasive surgical procedures. Transanal endoscopic microsurgery (TEM) is a well-developed minimally invasive technique for benign tumors in lower rectum...

We report the magnetic behavior of two intermetallic-based kagome lattices, Tb3Ru4Al12 and Er3Ru4Al12, crystallizing in the Gd3Ru4Al2-type hexagonal crystal structure, by measurements in the range 1.8-300 K with bulk experimental techniques (ac and dc magnetization, heat capacity, and magnetoresistance). The main finding is that the Tb compound, known to order antiferromagnetically below (T N =) 22 K, shows glassy characteristics at lower temperatures ([Formula: see text]15 K), thus characterizing this compound as a re-entrant spin-glass...

THE TRANSITION OF CHILDREN AFFECTED BY CANCER, THE FAMILY PERSPECTIVE.: During serious diseases in childhood such as cancer, the journey of the families is staged in information and transition times, which are essential stages for rebuilding family life. Support, orientation and proposals for a way forward are necessary for patients or their families not to be left in destructive isolation. Support actions for patients and their loved ones are implemented, particularly by associations.
