BACKGROUND: PF-00547659 is a fully human monoclonal antibody that binds to human mucosal addressin cell adhesion molecule-1 (MAdCAM-1) to selectively reduce lymphocyte homing to the intestinal tract. We aimed to assess the efficacy and safety of PF-00547659 in patients with moderate to severe ulcerative colitis. METHODS: This phase 2, randomised, double-blind, placebo-controlled clinical trial recruited patients aged 18-65 years from 105 centres in 21 countries, with a history (≥3 months) of active ulcerative colitis extending more than 15 cm beyond the anal verge (with a total Mayo score ≥6 and a Mayo endoscopic subscore ≥2) who had failed or were intolerant to at least one conventional therapy...

BACKGROUND: Colonic dilation is common in children with intractable functional constipation (FC). Our aim was to describe the association between segmental colonic dilation and colonic dysmotility in children with FC. METHODS: We performed a retrospective study on 30 children with intractable FC (according to the Rome III criteria) who had undergone colonic manometry and contrast enema within a 12-month time period. Colonic diameter was measured at 5 cm intervals from the anal verge up to the splenic flexure...

PURPOSE: Although the standard treatment for patients with locally advanced rectal cancer managed by preoperative chemoradiotherapy (CRT) is a radical resection, local excisions are used in highly-selective cases. Recently, transanal minimally-invasive surgery (TAMIS) has emerged as a feasible technique for local excision of midrectal lesions. We assess the feasibility of using TAMIS to treat patients with locally advanced rectal cancer who showed good response to CRT. METHODS: From October 2010 to June 2013, 35 consecutive patients with rectal cancer managed by using preoperative CRT underwent TAMIS...

Some of the major arboviruses with public health importance, such as dengue, yellow fever, Zika and West Nile virus are mosquito-borne or mosquito-transmitted Flavivirus. Their principal vectors are from the family Culicidae, Aedes aegypti and Aedes albopictus being responsible of the urban cycles of dengue, Zika and yellow fever virus. These vectors are highly competent for transmission of many arboviruses. The genetic variability of the vectors, the environment and the viral diversity modulate the vector competence, in this context, it is important to determine which vector species is responsible of an outbreak in areas where many vectors coexist...

BACKGROUND: Further optimisation of present standard chemoradiation is needed in patients with locally advanced rectal cancer. Veliparib, an oral poly(ADP-ribose) polymerase inhibitor, has been shown to enhance the antitumour activity of chemotherapy and radiotherapy in preclinical models. We aimed to establish the maximum tolerated dose and establish the recommended phase 2 dose of veliparib combined with neoadjuvant capecitabine and radiotherapy. METHODS: This phase 1b, open-label, multicentre, dose-escalation study was done at six hospitals (one in Australia and five in the USA)...

BACKGROUND: Anastomotic leakage is a potential major complication after colorectal surgery. The C-seal was developed to help reduce the clinical leakage rate. It is an intraluminal sheath that is stapled proximal to a colorectal anastomosis, covering it intraluminally and thus preventing intestinal leakage in case of anastomotic dehiscence. The C-seal trial was initiated to evaluate the efficacy of the C-seal in reducing anastomotic leakage in stapled colorectal anastomoses. METHODS: This RCT was performed in 41 hospitals in the Netherlands, Germany, France, Hungary and Spain...

BACKGROUND: Clinical trials investigating the effects of addition of oxaliplatin to neoadjuvant radiochemotherapy in locally advanced rectal cancers (LARCs) have brought controversial results for pathologic complete response as an endpoint. This randomized clinical trial investigated downstaging as a short-term surrogate for progression-free survival (PFS). METHODS: Patients with magnetic resonance imaging (MRI) defined T3, T4 or N+ histologically proven adenocarcinoma of rectum within 15 cm from anal verge were randomly assigned to receive 50-50...

Insulin producing cells derived from human embryonic stem cells (hESCs) or induced pluripotent stem cells (iPSCs) have for long been a promising, but elusive treatment far from clinical translation into type 1 diabetes therapy. However, the field is now on the verge of moving such insulin-producing cells into clinical trials. Although stem cell therapies provide great opportunities, there are also potential risks such as teratoma formation associated with the treatment. Many considerations are needed on how to proceed with clinical translation, including whether to use hESCs or iPSCs, and whether encapsulation of tissue will be needed...

Postburn lip deformities pose a significant set of challenges to reconstructive burn surgeons because of the complex anatomy, diverse functions, and specialized nature of the lip tissues. There has been a paucity of literature on restoration of the vermillion to date. The authors report on two patients who suffered burn injuries resulting in significant lip deformities who underwent a novel method of vermillion reconstruction with a full thickness anal verge skin graft. Both patients tolerated the procedure well without complications...

In Panama, human respiratory syncytial virus (HRSV) is responsible of 20 to 40 percent of acute respiratory infections in children under five years old. Currently, little is known about the genetic variability of HRSV in Central America and the Caribbean. Recently, we reported the genetic variability of HRSV-A, however; no studies on HRSV-B in Panama have been described yet. In this study, twenty-four sequences of Panamanian HRSV-B, from children (<5 years) with acute respiratory infections (ARI), collected from July 2008 to November 2012 were analyzed...

Nitric oxide (NO) is implicated in vasomotor control mechanisms altering the diameter of the vessels under various physiological and pathological conditions. There are two main NO production pathways, one NO synthase (NOS) independent (nitrate-nitrite-NO) and the other is NOS dependent (citrulline-arginine-NO). The objective of the study was to evaluate the effect of acute nitrate and citrulline supplementation on post ischemic vascular response in healthy subjects. Fourteen subjects performed two leg vascular occlusion tests, 3 days apart...
