Characteristics and outcomes of neonatal SARS-CoV-2 infection in the UK: a prospective national cohort study using active surveillance.

Chris Gale, Maria A Quigley, Anna Placzek, Marian Knight, Shamez Ladhani, Elizabeth S Draper, Don Sharkey, Cora Doherty, Helen Mactier, Jennifer J Kurinczuk,

BACKGROUND:Babies differ from older children with regard to their exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, data describing the effect of SARS-CoV-2 in this group are scarce, and guidance is variable. We aimed to describe the incidence, characteristics, transmission, and outcomes of SARS-CoV-2 infection in neonates who ... Read more >>

Planned early delivery or expectant management for late preterm pre-eclampsia (PHOENIX): a randomised controlled trial.

Lucy C Chappell, Peter Brocklehurst, Marcus E Green, Rachael Hunter, Pollyanna Hardy, Edmund Juszczak, Louise Linsell, Virginia Chiocchia, Melanie Greenland, Anna Placzek, John Townend, Neil Marlow, Jane Sandall, Andrew Shennan, ,

BACKGROUND:In women with late preterm pre-eclampsia, the optimal time to initiate delivery is unclear because limitation of maternal disease progression needs to be balanced against infant complications. The aim of this trial was to determine whether planned earlier initiation of delivery reduces maternal adverse outcomes without substantial worsening of neonatal ... Read more >>

Mediterranean-style diet in pregnant women with metabolic risk factors (ESTEEM): A pragmatic multicentre randomised trial.

Bassel H Al Wattar, Julie Dodds, Anna Placzek, Lee Beresford, Eleni Spyreli, Amanda Moore, Francisco J Gonzalez Carreras, Frances Austin, Nilaani Murugesu, Tessa J Roseboom, Maira Bes-Rastrollo, Graham A Hitman, Richard Hooper, Khalid S Khan, Shakila Thangaratinam, ,

BACKGROUND:Pregnant women with metabolic risk factors are at high risk of complications. We aimed to assess whether a Mediterranean-style diet reduces adverse pregnancy outcomes in high-risk women. METHODS AND FINDINGS:We conducted a multicentre randomised trial in 5 maternity units (4 in London and 1 in Birmingham) between 12 September 2014 ... Read more >>

Planned delivery or expectant management for late preterm pre-eclampsia: study protocol for a randomised controlled trial (PHOENIX trial).

Lucy C Chappell, Marcus Green, Neil Marlow, Jane Sandall, Rachael Hunter, Stephen Robson, Ursula Bowler, Virginia Chiocchia, Pollyanna Hardy, Edmund Juszczak, Louise Linsell, Anna Placzek, Peter Brocklehurst, Andrew Shennan,

BACKGROUND:Pre-eclampsia is a pregnancy disorder, characterised by hypertension and multisystem complications in the mother. The adverse outcomes of pre-eclampsia include severe hypertension, stroke, renal and hepatic injury, haemorrhage, fetal growth restriction and even death. The optimal time to instigate delivery to prevent morbidity when pre-eclampsia occurs between 34 and 37 weeks' ... Read more >>

Mediterranean diet based intervention in pregnancy to improve maternal and fetal outcomes: Methodological challenges and lessons learned from the multicentre ESTEEM study.

Bassel H Al Wattar, Julie Dodds, Anna Placzek, Eleni Spyreli, Sally Higgins, Amanda Moore, Richard Hooper, Lee Beresford, Tessa J Roseboom, Maira Bes-Rastrollo, Graham Hitman, Khalid S Khan, Shakila Thangaratinam, ,

Introduction:Evaluating complex dietary interventions such as Mediterranean diet in pregnancy presents unique methodological challenges. We present the challenges and the lessons learned from a multicentre randomised trial (ESTEEM) on Mediterranean-based dietary intervention in pregnancy. Methods:We recruited pregnant women who met our predefined inclusion criteria and randomised those with metabolic risk ... Read more >>

Effect of simple, targeted diet in pregnant women with metabolic risk factors on maternal and fetal outcomes (ESTEEM): study protocol for a pragmatic multicentre randomised trial.

Bassel H Al Wattar, Julie Dodds, Anna Placzek, Eleni Spyreli, Amanda Moore, Richard Hooper, Lee Beresford, Tessa J Roseboom, Maira Bes-Rastrollo, Graham Hitman, Khalid S Khan, Shakila Thangaratinam, ,

INTRODUCTION:Women with metabolic risk factors are at higher risk of adverse pregnancy outcomes. Mediterranean-based dietary interventions have the potential to minimise these risks. We aim to evaluate the effectiveness of a simple, targeted intervention modelled on Mediterranean diet in preventing maternal and fetal complications in pregnant women with metabolic risk ...

Variation in the reporting of outcomes among pregnant women with epilepsy: a systematic review.

Bassel H Al Wattar, Anna Placzek, Joy Troko, Alexander M Pirie, Khalid S Khan, Dougall McCorry, Javier Zamora, Shakila Thangaratinam, ,

Studies on pregnant women with epilepsy should evaluate both neurological and pregnancy outcomes. We undertook a systematic review of the literature of studies on pregnant women with epilepsy to collate the outcomes reported, and the quality of outcomes report in these studies. We searched major electronic databases (from 1999 until ... Read more >>

Dielectric relaxation study of the ion solvation and association of NaCF3SO3, Mg(CF3SO3)2, and Ba(ClO4)2 in N,N-dimethylformamide.

Anna Płaczek, Glenn Hefter, Hafiz M A Rahman, Richard Buchner,

Solutions of sodium trifluoromethanesulfonate, magnesium trifluoromethanesulfonate, and barium perchlorate in N,N-dimethylformamide (DMF) have been investigated using broadband dielectric relaxation spectroscopy at 25 °C. All spectra were dominated by a solvent relaxation process centered at ∼15 GHz but also exhibited one (for NaCF(3)SO(3)) or two (for the 2:1 salts) low-amplitude processes, ... Read more >>

Coordination chemistry study of hydrated and solvated lead(II) ions in solution and solid state.

Ingmar Persson, Krzysztof Lyczko, Daniel Lundberg, Lars Eriksson, Anna Płaczek,

The coordination chemistry of lead(II) in the oxygen donor solvents water, dimethylsulfoxide (dmso, Me(2)SO), N,N-dimethylformamide (dmf), N,N-dimethylacetamide (dma), N,N'-dimethylpropyleneurea (dmpu), and 1,1,3,3-tetramethylurea (tmu), as well as in the sulfur donor solvent N,N-dimethylthioformamide (dmtf), has been investigated by extended X-ray absorption fine structure (EXAFS) and/or large angle X-ray scattering (LAXS) in ...

Molar volumes and heat capacities of electrolytes and ions in N,N-dimethylformamide.

Anna Płaczek, Wacław Grzybkowski, Glenn Hefter,

Densities and heat capacities of various 1:1 and higher-charged electrolytes have been measured in N,N-dimethylformamide (DMF) at 25 degrees C using a series-connected flow densimeter and Picker calorimeter. Standard molar volumes V (o) and isobaric heat capacities C p (o) derived from these data were split into their ionic contributions ... Read more >>
