Training in bariatric endoscopy

Bariatric endoscopy has emerged as an alternative treatment modality for obesity and its related comorbidities. The field includes a wide range of procedures from endoscopic treatment for complications of bariatric surgery to performing primary endoscopic procedures for weight loss. Additionally, knowledge of adjunctive lifestyle therapy and pharmacotherapy are also critical to ensuring successful outcomes. This article reviews specific goals, resources, and specific steps for acquisition of specific cognitive and technical skills in bariatric endoscopic procedures.     

Nutritional status and bioelectrical phase angle assessment in adult Crohn disease patients receiving anti-TNFα therapy

BackgroundAltered body composition is frequently observed in Crohn’s disease (CD) patients.AimsTo investigate the nutritional status, and the effect of different therapeutic regimes in adult CD patients.MethodsFat free mass (FFM) and BIA-derived phase angle (PhA) were assessed in 45 CD patients, 22 on conventional therapy (CT) and 23 on maintenance therapy with infliximab (MT). Nutritional status was also assessed in 12 CD patients before and following the induction protocol with infliximab. BIA data of CD patients were compared with those of 20 healthy asymptomatic volunteers. In CD patients C Reactive Protein (CRP) and albuminaemia dosage were obtained.ResultsThe mean values of PhA and of FFM were significantly lower in CT patients when compared with control group and MT patients. Following infliximab treatment FFM increased, although not significantly, while mean phase angle value significantly increased from 4.6 ± 0.3 to 6.2 ± 0.4 (p < 0.05). CRP was significantly lower in MT patients compared to that in CT patients.ConclusionCD patients on conventional therapy showed a lower FFM and a lower mean phase angle score compared to those on infliximab therapy. Following infliximab treatment the mean phase angle score normalized. PhA is a reliable nutritional indicator in IBD patients and could be considered as an additional tool for assessing response to treatment.     

Facilitating comfort for hospitalized patients using non-pharmacological measures: Preliminary development of clinical practice guidelines

Nurses often use non-pharmacological measures to facilitate comfort for patients within the hospital setting. However, guidelines for use of these measures are commonly inadequate or absent. This paper presents 12 clinical practice guidelines that were developed from the findings of a literature review into non-pharmacological measures that are thought to facilitate patient comfort. The non-pharmacological measures addressed in these guidelines are: Aromotherapy, Distraction, Guided Imagery, Laughter, Massage, Music, Reiki, Heat or Cold, Meditation, Reflexology, Reposition and Transcutaneous Electrical Nerve Stimulation. These are preliminary guidelines for the use of non-pharmacological measures and further research and development of such guidelines is recommended.     

Outcome in ulcerative colitis after switch from adalimumab/golimumab to infliximab: A multicenter retrospective study

Background

Anti-TNF therapies infliximab (IFX), adalimumab (ADA), and golimumab (GOL) are approved for treating moderate to severe ulcerative colitis (UC). In UC, only the switch from IFX to ADA has been investigated, reaching no more than 10–43% remission rates at 12 months.

Safety of aerosolized INS 365 in patients with mild to moderate cystic fibrosis: results of a phase I multi-center study

Cystic fibrosis (CF) is characterized by defective cystic fibrosis transmembrane regulator (CFTR) expression and function, associated with abnormal ion transport and mucociliary clearance, and clinical lung disease. Triphosphate nucleotides such as uridine-5'-triphosphate (UTP) and INS 365, may be useful for CF through actions, mediated via P2Y(2) extracellular receptors, on chloride and liquid secretion, and ciliary beat frequency. INS 365 may offer chemical stability advantages over UTP. In a randomized, double-blind, multicenter phase I study, we studied the safety and maximally tolerated dose of escalating, single doses of aerosolized INS 365, in adult and pediatric patients with mild to moderate CF lung disease (FEV(1) > or = 45% predicted). In four successive dose cohorts of adult patients (n = 12 per cohort, age > or = 18 years) and four successive pediatric dose cohorts (n = 12 per cohort, age 5-12 years), patients were randomized 3:1 active/placebo (0.9% saline) to evaluate doses of 20, 40, 80, and 100 mg INS 365 delivered by nebulizer (Pari Star ). Sputum was collected pre- and post-dosing to obtain preliminary results on clinical efficacy. After each dose cohort, a Data Safety Monitoring Committee (DSMC) reviewed the data. Forty-eight adult and 36 pediatric patients completed the protocol (up to 100 mg for adults, 80 mg for pediatric patients). The predominant adverse events were cough, wheezing, chest tightness, and a decrease in FEV(1) (occurring in 8/48 adults, and 5/36 pediatric patients), which occurred predominantly in the 80-mg and 100-mg dose cohorts. Though a few adult patients had a tendency to increase sputum production, there was little consistent effect noted on sputum production in this acute, single-dose study. The data suggest that aerosolized INS 365 is safe when delivered at single doses of up to 40 mg in adults and children with CF, but that higher doses are unlikely to be tolerated.

Investigational therapies currently in Phase II clinical trials for the treatment of pelvic serous carcinomas

Introduction: Pelvic serous carcinomas (PSCs) are a controversial entity, which mostly comprise fallopian tube carcinoma (FTC), primary peritoneal carcinoma (PPC) and serous ovarian carcinoma (OC). Despite incremental attention towards understanding pelvic serous carcinogenesis, the gold standard treatment and survival rates have not substantially changed in these last decades.

Areas covered: This review summarizes and gives a critical overview of the ongoing Phase II trials investigating therapies for PSC.

Expert opinion: Several novel molecules have been developed and are currently under investigation for the treatment of PSC, including FTC, PPC and serous OC. The trend of novel targeted agents is one towards individualized, tailored therapy, based on the molecular and biological differences that characterize tumors that seem similar based solely on histological analysis. The task of developing new molecules is particularly difficult for PSC, given the recurrent development of new patterns of drug resistance. However, even if current research is focused towards identifying the best treatments for each woman with a molecularly defined disease, a deeper knowledge of the molecular biology and genetics underlying FTC and its relation as a precursor of PSC is needed.
