A randomised control trial of low glycaemic index carbohydrate diet versus no dietary intervention in the prevention of recurrence of macrosomia

<p>Abstract</p> <p>Background</p> <p>Maternal weight and maternal weight gain during pregnancy exert a significant influence on infant birth weight and the incidence of macrosomia. Fetal macrosomia is associated with an increase in both adverse obstetric and neonatal outcome, and also confers a future risk of childhood obesity. Studies have shown that a low glycaemic diet is associated with lower birth weights, however these studies have been small and not randomised <abbrgrp><abbr bid="B1">1</abbr><abbr bid="B2">2</abbr></abbrgrp>. Fetal macrosomia recurs in a second pregnancy in one third of women, and maternal weight influences this recurrence risk <abbrgrp><abbr bid="B3">3</abbr></abbrgrp>.</p> <p>Methods/Design</p> <p>We propose a randomised control trial of low glycaemic index carbohydrate diet vs. no dietary intervention in the prevention of recurrence of fetal macrosomia.</p> <p>Secundigravid women whose first baby was macrosomic, defined as a birth weight greater than 4000 g will be recruited at their first antenatal visit.</p> <p>Patients will be randomised into two arms, a control arm which will receive no dietary intervention and a diet arm which will be commenced on a low glycaemic index diet.</p> <p>The primary outcome measure will be the mean birth weight centiles and ponderal indices in each group.</p> <p>Discussion</p> <p>Altering the source of maternal dietary carbohydrate may prove to be valuable in the management of pregnancies where there has been a history of fetal macrosomia. Fetal macrosomia recurs in a second pregnancy in one third of women. This randomised control trial will investigate whether or not a low glycaemic index diet can affect this recurrence risk.</p> <p>Current Controlled Trials Registration Number</p> <p>ISRCTN54392969</p

ICON 2019: International Scientific Tendinopathy Symposium Consensus: Clinical Terminology

© Author(s) (or their employer(s)) 2019. No commercial re-use. See rights and permissions. Published by BMJ.Background Persistent tendon pain that impairs function has inconsistent medical terms that can influence choice of treatment.1 When a person is told they have tendinopathy by clinician A or tendinitis by clinician B, they might feel confused or be alarmed at receiving what they might perceive as two different diagnoses. This may lead to loss of confidence in their health professional and likely adds to uncertainty if they were to search for information about their condition. Clear and uniform terminology also assists inter-professional communication. Inconsistency in terminology for painful tendon disorders is a problem at numerous anatomical sites. Historically, the term ‘tendinitis’ was first used to describe tendon pain, thickening and impaired function (online supplementary figure S1). The term ‘tendinosis’ has also been used in a small number of publications, some of which were very influential.2 3 Subsequently, ‘tendinopathy’ emerged as the most common term for persistent tendon pain.4 5 To our knowledge, experts (clinicians and researchers) or patients have never engaged in a formal process to discuss the terminology we use. We believe that health professionals have not yet agreed on the appropriate terminology for painful tendon conditions.Peer reviewedFinal Accepted Versio

A double-station meteor camera set-up in the Canary Islands – CILBO

This paper describes a double-station camera set-up in the Canary Islands, called CILBO (Canary Island Long-Baseline Observatory). Image-intensified video cameras – one camera on Tenerife and one on La Palma – monitor the same volume of the atmosphere. They are located in automated roll-off roofs. From the obtained data, the meteoroid trajectory can be computed. A second camera on Tenerife is equipped with an objective grating. For bright meteors (typically 0 mag or brighter), a spectrum is recorded which allows constraining the chemical composition of the meteor. The system is completely automated and sends the obtained data after every observation night to a central FTP server. It has been in operation for about 2 yr and the first scientific results have been produced

Report from the ISSI team meeting "A Virtual Observatory for meteoroids''

The content and format of the Virtual Meteor Observatory (VMO) was discussed in a one-week team meeting at the International Space Science Institute (ISSI) in Bern, Switzerland, in 2008 November. The current status of the VMO (in 'beta' version) was presented and discussed. The visual and camera sections are ready to be populated with data; a fireball section will be created. The radio/radar section is still open. In the discussion, several points were addressed: The relation to the Planetary Science Archive, treatment of shower catalogues, how to best perform astrometry, how to compute and store orbital data. The meeting ended by producing a list of future work, which is given at the end of the paper
