A proposed approach may help systematic reviews retain needed expertise while minimizing bias from nonfinancial conflicts of interest.

Objectives: Groups such as the Institute of Medicine emphasize the importance of attention to financial conflicts of interest. Little guidance exists, however, on managing the risk of bias for systematic reviews from nonfinancial conflicts of interest. We sought to create practical guidance on ensuring adequate clinical or content expertise while maintaining independence of judgment on systematic review teams.

Safety of Vaccines Used for Routine Immunization in the United States.

Objectives: To conduct a systematic review of the literature on the safety of vaccines recommended for routine immunization of children, adolescents, and adults in the United States as of 2011.

Data Sources: We included placebo-controlled clinical trials and cohort studies comparing vaccinated and unvaccinated patients. We also included the following types of post-licensure analyses: case-control studies, self-controlled case series, and multivariate risk factor analyses.

Reporting of context and implementation in studies of global health interventions: a pilot study.

Background: There is an increasing push for 'evidence-based' decision making in global health policy circles. However, at present there are no agreed upon standards or guidelines for how to evaluate evidence in global health. Recent evaluations of existing evidence frameworks that could serve such a purpose have identified details of program context and project implementation as missing components needed to inform policy.

Multicenter analysis of body mass index, lung function, and sputum microbiology in primary ciliary dyskinesia.

Background: No studies longitudinally, simultaneously assessed body mass index (BMI) and spirometry in primary ciliary dyskinesia (PCD).

Methods: We determined BMI and spirometry in 158 PCD children and adolescents from London, UK (n = 75), Naples, Italy (n = 23) and Copenhagen, Denmark (n = 60) at first presentation and during follow-up. Annual BMI and spirometry were prospectively collected and analyzed over blocks of 2, 4, and 6 consecutive years.

A surveillance system to assess the need for updating systematic reviews.

Background: Systematic reviews (SRs) can become outdated as new evidence emerges over time. Organizations that produce SRs need a surveillance method to determine when reviews are likely to require updating. This report describes the development and initial results of a surveillance system to assess SRs produced by the Agency for Healthcare Research and Quality (AHRQ) Evidence-based Practice Center (EPC) Program.

Systematic tuning of the conduction mechanisms in ferroelectric thin films.

We have investigated the macroscopic and microscopic properties of large sets of Ba0.7Sr0.3TiO3 thin films including several substitution rates of manganese.

New perspectives in Respiratory Syncitial Virus infection.

Respiratory syncitial virus (RSV) is the most common cause of lower respiratory tract infections (LRTI) in children worldwide and it is associated with significant childhood morbidity. Acute infection may result in respiratory failure with varying degrees of severity, and increasing evidence supports a role of RSV infection as a key determinant for the development of subsequent chronic respiratory disease. Independent predictors of RSV severity include; prematurity, congenital heart disease, cystic fibrosis, immune defects and neuromuscular disorders.

Non invasive assessment of lung disease in ataxia telangiectasia by high-field magnetic resonance imaging.

Purpose: A sensitive imaging technique that assesses ataxia telangiectasia (AT) lung disease without ionizing radiation is highly desirable. We designed a study to evaluate lung changes using magnetic resonance imaging (MRI), and to investigate the relationships among severity and extent of pulmonary abnormalities and clinical, microbiological and functional data in children and young adults with AT.

Methods: Fifteen AT patients (age, 11.

A comparison of frameworks evaluating evidence for global health interventions.

Jill Luoto and colleagues apply different frameworks to the same body of evidence for three advocated global health interventions and compare the ratings and policy recommendations resulting from each.

Novel organic LED structures based on a highly conductive polymeric photonic crystal electrode.

In this work we demonstrate the possibility to realize a novel unconventional ITO-free organic light emitting diode (OLED) utilizing a photonic polymeric electrode. Combining electron beam lithography and a plasma etching process to partially structure the highly conductive poly(3,4 ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) it is possible to realize an embedded photonic crystal (PC) structure. The realized PC-anode drastically reduces the light trapped in the OLED, demonstrating the possibility to eliminate further process stages and making it easier to use this technology even on rollable and flexible substrates.

Seeing the forest tree by tree: super-resolution light microscopy meets the neurosciences.

Light microscopy can be applied in vivo and can sample large tissue volumes, features crucial for the study of single neurons and neural circuits. However, light microscopy per se is diffraction-limited in resolution, and the substructure of core signaling compartments of neuronal circuits--axons, presynaptic active zones, postsynaptic densities and dendritic spines-can be only insufficiently characterized by standard light microscopy. Recently, several forms of super-resolution light microscopy breaking the diffraction-imposed resolution limit have started to allow highly resolved, dynamic imaging in the cell-biologically highly relevant 10-100 nanometer range ('mesoscale').

Bariatric surgery for weight loss and glycemic control in nonmorbidly obese adults with diabetes: a systematic review.

Importance: Bariatric surgery is beneficial in persons with a body mass index (BMI) of 35 or greater with obesity-related comorbidities. There is interest in using these procedures in persons with lower BMI and diabetes.

Objective: To assess the association between bariatric surgery vs nonsurgical treatments and weight loss and glycemic control among patients with diabetes or impaired glucose tolerance and BMI of 30 to 35.

Fabrication of novel two-dimensional nanopatterned conductive PEDOT:PSS films for organic optoelectronic applications.

This paper presents a novel strategy to fabricate two-dimensional poly(3,4 ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) photonic crystals (PCs) combining electron beam lithography (EBL) and plasma etching (PE) processes. The surface morphology of PEDOT:PSS PCs after mild oxygen plasma treatment was investigated by scanning electron microscopy. The effects on light extraction are studied experimentally.

A new biological approach to guided bone and tissue regeneration.

The purpose of this study was to determine the potential of platelet-rich fibrin (PRF) membranes used for guided bone and tissue regeneration. A patient with insufficient alveolar ridge width in aesthetic zone was enrolled. The patient's blood was centrifuged to obtain PRF membranes.

Guided-wave electro-optic characterization of BaTiO3 thin films using the prism coupling technique.

Ferroelectric BaTiO3 (BTO) thin films are grown by RF sputtering onto an indium tin oxide bottom electrode on a MgO single-crystal substrate. We have studied here the optical properties by the prism coupling technique. We report the ordinary and extraordinary refractive indices of the films, the film thickness, and the optical losses that are obtained on the planar waveguides: n0=2.

Hypertransaminasemia and fatal lung disease: a case report.

Glycogenosis type II (Pompe disease) is a rare autosomal recessive genetic disorder caused by mutations in the gene encoding the lysosomal enzyme acid α-glucosidase. The classic form is characterized by severe cardiac involvement, generalized hypotonia and exitus early in life. Presenting symptoms and signs of the disease may be neglected or underestimated, thus delaying the diagnosis.

Clinical application of exhaled nitric oxide measurement in pediatric lung diseases.

Fractional exhaled nitric oxide (FeNO) is a non invasive method for assessing the inflammatory status of children with airway disease. Different ways to measure FeNO levels are currently available. The possibility of measuring FeNO levels in an office setting even in young children, and the commercial availability of portable devices, support the routine use of FeNO determination in the daily pediatric practice.

Nonmedical interventions for children with ASD: recommended guidelines and further research needs.

Objective: To use the findings of a systematic review of scientific evidence to develop consensus guidelines on nonmedical interventions that address cognitive function and core deficits in children with autism spectrum disorders (ASDs) and to recommend priorities for future research.

Methods: The guidelines were developed by a Technical Expert Panel (TEP) consisting of practitioners, researchers, and parents. A systematic overview of research findings was presented to the TEP; guideline statements were drafted, discussed, debated, edited, reassessed, and presented for formal voting.

Donor risk factors, retrieval technique, preservation and ischemia/reperfusion injury in pancreas transplantation.

Purpose Of Review: Pancreas transplantation is still hampered by a high incidence of early graft loss, and organ quality concerns result in high nonrecovery/discard rates. Demographic donor characteristics, surgical retrieval strategy, preservation fluid and ischemia time are crucial factors in the process of organ selection and are discussed in this review.

Recent Findings: The donor shortage is driving an increasing utilization of nonideal organs which would previously have been identified as unsuitable.
