Background: Access to a wide range of contraceptive methods improves prevention of unintended pregnancy by ensuring the best method fit for each individual. We compared approval times of new hormonal contraceptives by Health Canada, the US Food and Drug Administration (FDA), and the UK Medicines and Healthcare Products Regulatory Agency (MHRA). Methods:We obtained dates of applications to Health Canada, the FDA and the MHRA for contraceptive methods approved from January 2000 to January 2015. We used public data sources and direct correspondence, and excluded generic versions of previously approved drugs. The primary outcome of interest was median time to approval for novel hormonal contraceptives. Secondary outcomes included the median time to approval for all hormonal contraceptives and the number of approved hormonal contraceptives comparing countries studied, as well as the median time for approval of novel compared with nonnovel hormonal contraceptives within each country.Results: During this period 16 contraceptives were approved in Canada, 26 in the US and 14 in the UK. Applications for novel contraceptives were initiated later in Canada, and time to approval was longer in Canada than in the US (p = 0.03).

Objectives Risk factors for sudden infant death syndrome include premature birth, maternal smoking, prone or side sleeping position, sleeping with blankets, sharing a sleeping surface with an adult, and sleeping without an adult in the room. In this study, we compare parents’ responses on sleep patterns in premature and term infants with medical complexity. Methods Parents of children enrolled in the Canadian Respiratory Syncytial Virus Evaluation Study of Palivizumab were phoned monthly regarding their child’s health status until the end of each respiratory syncytial virus season. Baseline data were obtained on patient demographics, medical history, and neonatal course. Responses on adherence to safe sleep recommendations were recorded as part of the assessment. Results A total of 2,526 preterms and 670 term infants with medical complexity were enrolled. Statistically significant differences were found in maternal smoking rates between the two groups: 13.3% (preterm); 9.3% (term) infants (χ 2=8.1, df=1, P=0.004) and with respect to toys in the crib: 12.3% (term) versus 5.8% preterms (χ 2=24.5, df=1, P<0.0005). Preterm infants were also significantly more likely to be placed prone to sleep (8.8%), compared with term infants (3.3%), (χ 2=18.1, df=1, P<0.0005). Conclusion All the infants in this study had frequent medical contacts. There is a greater prevalence of some risk factors for sudden infant death syndrome in preterm infants compared to term infants with medical complexity. Specific educational interventions for vulnerable infants may be necessary.
