Vaginal progesterone as luteal phase support in natural cycle frozen-thawed embryo transfer (ProFET): protocol for a multicentre, open-label, randomised controlled trial.

Introduction: Vaginal progesterone supplementation is frequently given to patients receiving frozen embryo transfer (FET) in the natural cycle aiming to increase the chance of pregnancy and live birth. To date, only a few studies have investigated if progesterone supplementation is beneficial in these cycles and the level of evidence for progesterone supplementation is very low.

Methods And Analysis: The ProFET trial is a multicentre, open-label, randomised controlled trial powered for this investigation, including 1800 women with regular menstrual cycles (24-35 days), aged 18-43 years planned for natural cycle-FET receiving a single blastocyst for transfer.

Acute illnesses in young children and family response.

Swedish speaking parents of 446 children, all around one year of age and living in the suburbs of Stockholm, participated in a three-week diary study. The aim was to describe the pattern of illnesses in children and the measures taken in the family and to correlate the findings with the socio-economic conditions of the family. A health complaint, most frequently running or blocked nose or a cough, was recorded for about 1/3 of the days of observation.
