A Conscious Sedation Protocol for Videolaryngostroboscopy in Pediatric Patients
Objective. To determine best sedation protocol for videolaryngostroboscopy in children unable to tolerate non-sedated evaluation. Materials and Methods. Consecutive case series of 10 children with voice disturbances, unable to tolerate nonsedated videolaryngostroboscopy at an academic tertiary care children's hospital. Flexible fiberoptic videolaryngostroboscopy was performed and interpreted by pediatric otolaryngologist and speech and language pathologist. Sedation was administered with newly described protocol that allowed functional portion of evaluation. Main Outcome Measures: ability to follow commands and tolerate flexible fiberoptic videolaryngostroboscopy. Secondary Outcome Measures: total phonation time, complications, need for subsequent videolaryngostroboscopic attempts, clinical outcomes, and follow-up. Results. 10 children underwent procedure under conscious sedation. 9/10 children were able to perform simple tasks and maintain adequate phonation time to complete stroboscopic exam. 1/10 patients failed to complete exam because of crying during entire exam. Mean exam time was 2 minutes 52 seconds (SD 86 seconds), phonation time is 1 minute 44 seconds (SD 60 seconds), and number of tasks completed was 10.5 (SD 8.6). Conclusions. Conscious sedation for videolaryngostroboscopy can be safely and effectively performed in children unable to comply with nonsedated examination. Such studies provide valuable diagnostic information to make a diagnosis and to devise a treatment plan

What do we know about unassisted smoking cessation in Australia? A systematic review, 2005â2012
Context A significant proportion of smokers who quit do so on their own without formal help (i.e. without professionally or pharmacologically mediated assistance), yet research into how smokers quit focuses primarily on assisted methods of cessation. Objective To systematically review recent smoking cessation research in Australia, a nation advanced in tobacco control, to determine what is known about smokers who quit unassisted in order to (1) inform a research agenda to develop greater understanding of the many smokers who quit unassisted and (2) elucidate possible lessons for policy and mass communication about cessation. Methods In January 2013, four e-databases and the grey literature were searched for articles published 2005â2012 on smoking cessation in Australia. Articles focusing solely on interventions designed to stimulate cessation were excluded, as were articles focusing solely on assisted cessation, leaving articles reporting on smokers who quit unassisted. Data from articles reporting on unassisted cessation were extracted and grouped into related categories. Results 248 articles reported on smoking cessation, of which 63 focused solely on interventions designed to stimulate cessation, leaving 185 reporting on the method of cessation (âhowâ a smoker quits). Of these, 166 focused solely on assisted cessation, leaving 19 reporting, either directly or indirectly, on smokers who quit unassisted. Data from these studies indicated 54%â69% of ex-smokers quit unassisted, and 41%â58% of current smokers had attempted to quit unassisted. Conclusions The majority of Australian smokers quit or attempt to quit unassisted, yet little research has been dedicated to understanding this process. Almost all research that reported unassisted cessation referenced it as a comparator to the focal point of assisted cessation. Public health may benefit from insights gained from greater research into the cessation method used by most smokers. Suggestions and a rationale for such research are provided.National Health and Medical Research Council, Australi

Study of collective effects in a low-emittance PEP lattice
This paper summarizes the work on the collective effects studied during the previously described low-emittance operation of PEP. These studies looked at the single bunch and multi-bunch current limits consistent with stable beam operation. The lower than expected current limits and observed coherent beam oscillations, together with methods of countering them, were considered at a recent SSRL workshop. A result of these studies has been that the lower momentum compaction factor and large beta function variations of the low-emittance lattice (a common feature of all proposed high-energy radiation sources) contribute to enhanced collective effects, limiting the early achievable beam intensity to less than the desired 100 mA. The calculational models, especially because of the uncertainty of the beam impedance models, have limited predictability for these effects and will benefit from continued studies of this kind
Development of a 20-item food frequency questionnaire to assess a 'prudent' dietary pattern among young women in Southampton
Objective: to develop a short food frequency questionnaire (FFQ) that can be used among young women in Southampton to assess compliance with a prudent dietary pattern characterized by high consumption of wholemeal bread, fruit and vegetables, and low consumption of sugar, white bread, and red and processed meat.Methods: diet was assessed using a 100-item interviewer-administered FFQ in 6129 non-pregnant women aged 20â34 years. In total, 94 of these women were re-interviewed 2 years later using the same FFQ. Subsequently, diet was assessed in 378 women attending SureStart Children's Centres in the Nutrition and Well-being Study (NWS) using a 20-item FFQ. The 20 foods included were those that characterized the prudent dietary pattern.Results: the 20-item prudent diet score was highly correlated with the full 100-item score (r=0.94) in the Southampton Women's Survey (SWS). Both scores were correlated with red blood cell folate (r=0.28 for the 100-item score and r=0.25 for the 20-item score). Among the women re-interviewed after 2 years, the change in prudent diet score was correlated with change in red cell folate for both the 20-item (rS=0.31) and 100-item scores (rS=0.32). In the NWS a strong association between the 20-item prudent diet score and educational attainment (r=0.41) was observed, similar to that seen in the SWS (r=0.47).Conclusions: the prudent diet pattern describes a robust axis of variation in diet. A 20-item FFQ based on the foods that characterize the prudent diet pattern has clear advantages in terms of time and resources, and is a helpful tool to characterize the diets of young women in Southampto

Increased rates of Guillain-Barré syndrome associated with Zika virus outbreak in the Salvador metropolitan area, Brazil
<div><p>In mid-2015, Salvador, Brazil, reported an outbreak of Guillain-BarrĂ© syndrome (GBS), coinciding with the introduction and spread of Zika virus (ZIKV). We found that GBS incidence during AprilâJuly 2015 among those â„12 years of age was 5.6 cases/100,000 population/year and increased markedly with increasing age to 14.7 among those â„60 years of age. We conducted interviews with 41 case-patients and 85 neighborhood controls and found no differences in demographics or exposures prior to GBS-symptom onset. A higher proportion of case-patients (83%) compared to controls (21%) reported an antecedent illness (OR 18.1, CI 6.9â47.5), most commonly characterized by rash, headache, fever, and myalgias, within a median of 8 days prior to GBS onset. Our investigation confirmed an outbreak of GBS, particularly in older adults, that was strongly associated with Zika-like illness and geo-temporally associated with ZIKV transmission, suggesting that ZIKV may result in severe neurologic complications.</p></div
