Association between the Mode of Delivery and Vertical Transmission of Human Papillomavirus.

Human papillomavirus (HPV) can be vertically transmitted. Our objective was to measure the association between the mode of delivery and the detection of HPV in infants. We used data collected from pregnant women during the HERITAGE study.

Association between Human Papillomavirus 16 Viral Load in Pregnancy and Preterm Birth.

Recent evidence shows increased preterm birth risk with human papillomavirus-16 (HPV16) infection during pregnancy. This study aimed to measure the association between HPV16 viral load during pregnancy and preterm birth. We used data from participants in the HERITAGE study.

Risk factors for placental human papillomavirus infection.

Objective: Human papillomavirus (HPV) has been associated with adverse pregnancy outcomes but placental HPV infection has been rarely studied. The objective was to determine the proportion of HPV-positive placentas and the associated risk factors among HPV-positive women during pregnancy.

Methods: We analysed data from pregnant women enrolled in HERITAGE cohort study between 2010 and 2016 with positive vaginal HPV infection during the first trimester of pregnancy (n=354).

Association Between Human Papillomavirus Infection Among Pregnant Women and Preterm Birth.

Importance: Preterm birth remains a leading cause of perinatal mortality and lifelong morbidity worldwide. The cause of most preterm births is unknown, although several infectious processes have been implicated.

Objective: To assess whether human papillomavirus (HPV) infection, a frequent infection among women of childbearing age, is associated with preterm birth.

Antibodies to human papillomavirus types 6, 11, 16 and 18: Vertical transmission and clearance in children up to two years of age.

There is a paucity of data on the dynamics of human papillomavirus (HPV) antibodies in children. We aimed to describe the vertical transmission and clearance of antibodies against HPV6, 11, 16 and 18 in children. We used data from pregnant women recruited into the HERITAGE cohort study between 2009 and 2012 who were positive for HPV-DNA at baseline.

Exploration of the effect of human papillomavirus (HPV) vaccination in a cohort of pregnant women in Montreal, 2010-2016.

HPV vaccination efficacy has been shown in clinical trials but it is important to verify population level vaccine effectiveness (VE). We aimed to explore VE and herd effect using HPV infection data from a cohort study of Canadian pregnant women. We analyzed the baseline data of the HERITAGE study, which includes pregnant women recruited in Montreal between 2010-2012 and 2015-2016.

Human papillomavirus (HPV) perinatal transmission and risk of HPV persistence among children: Design, methods and preliminary results of the HERITAGE study.

Perinatal route of transmission of human papillomavirus (HPV) has been demonstrated in several small studies. We designed a large prospective cohort study (HERITAGE) to better understand perinatal HPV. The objective of this article is to present the study design and preliminary data.

Effect of dual-chamber pacemaker implantation on aortic dilatation in patients with congenital heart block.

Ascending aortic dilatation (AoD) in patients with structurally normal hearts and congenital heart block (CHB) has been previously described. The cause and management of AoD are yet to be determined. The aim of this study was to test the hypothesis that AoD in children with CHB regresses after the implantation of cardiac dual-chamber pacemakers (PMs).

Mother and stranger: an electrophysiological study of voice processing in newborns.

In the mature adult brain, there are voice selective regions that are especially tuned to familiar voices. Yet, little is known about how the infant's brain treats such information. Here, we investigated, using electrophysiology and source analyses, how newborns process their mother's voice compared with that of a stranger.

Effects of selective serotonin reuptake inhibitors and venlafaxine during pregnancy in term and preterm neonates.

Objectives: Our goals were to (a) describe neonatal behavioral signs in a group of newborns exposed in utero to selective serotonin reuptake inhibitors or venlafaxine at the time of delivery, (b) compare the rate of neonatal behavioral signs, prematurity, and admission to specialized neonatal care between a group of exposed and unexposed newborns, and (c) compare the effects in exposed preterm and term newborns.

Patients And Methods: This was a retrospective cohort study including mothers taking selective serotonin reuptake inhibitors or venlafaxine during the third trimester and mothers who were not taking any antidepressants, psychotropic agents, or benzodiazepines at the time of delivery of their newborns. Neonatal behavioral signs included central nervous, respiratory, and digestive systems, as well as hypoglycemia and the need for phototherapy.

Acute adenitis in children: clinical course and factors predictive of surgical drainage.

Objectives: To describe clinical course of children hospitalized for a first episode of acute unilateral infectious adenitis and to identify factors predictive of surgical lymph node drainage.

Methods: We reviewed medical records of children from 0 to 17 years of age discharged from a tertiary care pediatric center with a diagnosis of adenitis between 1 April 1996 and 31 March 2001. Patients were included if they had acute (< or = 10 days) unilateral lymph node swelling greater or equal to 2.
