Impact of maternal prenatal and parental postnatal stress on 1-year-old child development: results from the OTIS antidepressants in pregnancy study.

Perinatal psychological stress has been associated with unfavorable maternal and neonatal outcomes. We aimed to assess the impact of perinatal stress on infant development at 1 year of age. We recruited pregnant women calling North American Teratogen Information Services or attending outpatient clinics at CHU Sainte Justine (Montreal) between 2008 and 2010 and their spouses. To be part of our study, women had to be (1) >18 years of age, (2) <15 weeks of gestational age at recruitment, (3) living within 250-km radius of Montreal, and (4) taking antidepressants or non-teratogenic drugs. Stress was assessed using the telephone-administered four-item perceived stress scale during pregnancy in mothers and at 2 months postpartum in both parents. Child development at 1 year of age was evaluated with the Bayley III scales. Socio-demographic and potential confounders were collected through telephone interviews. Multivariable linear regression models were built to assess the association between perinatal parental stress and child development. Overall, 71 couples and their infants were included. When adjusted for potential confounders, maternal prenatal stress was positively associated with motor development (adjusted ß = 1.85, CI 95 % (0.01, 3.70)). Postpartum maternal and paternal stresses were negatively associated with motor and socio-emotional development, respectively (adjusted ß = -1.54, CI 95 % (-3.07, -0.01) and adjusted ß = -1.67, CI 95 % (-3.25, -0.10), respectively). Maternal and paternal postnatal stress seems to be harmful for the motor and socio-emotional development in 1-year-old children. No association was demonstrated between parental stress and cognitive, language, and adaptive behavioral development. However, prenatal maternal stress appears to improve motor skills.

Reliability and validity of the 4-item perceived stress scale among pregnant women: results from the OTIS antidepressants study.

We aimed to estimate the reliability of the 4-item Perceived Stress Scale (PSS) and its validity in predicting maternal depression and quality of life (QoL). Data regarding stress, depression and QoL were collected during pregnancy among a sub-sample from the Organization of Teratology Information Specialists Antidepressants in Pregnancy Cohort. The 4-item PSS demonstrated acceptable internal consistency (Cronbach's alpha coefficient = .79), alternate forms stability reliability with the 10-item PSS (Pearson correlation coefficient r = .63; p < .001), convergent validity with the Edinburgh Postnatal Depression Scale (r = .67; p < .001), and concurrent validity with the mental health component of the Short-Form-12 (r = -.62; p < .001) as a measure of QoL. The 4-item PSS is a valid and useful tool for assessing maternal stress during pregnancy.

Cross-Reactivity to Cephalosporins and Carbapenems in Penicillin-Allergic Patients: Two Systematic Reviews and Meta-Analyses.

BACKGROUND: There is no recent systematic review on the risk of cross-reactivity to cephalosporins and carbapenems in penicillin-allergic patients despite many new studies on the subject. All past reviews have several limitations such as not including any patient with a T-cell-mediated penicillin allergy. OBJECTIVES: To determine the risk of cross-reactivity to cephalosporins and carbapenems in patients with a proven IgE- or T-cell-mediated penicillin allergy. To measure the association between R1 side chain similarity on cephalosporins and penicillins and the risk of cross-reactivity. METHODS: MEDLINE and EMBASE were searched from January 1980 to March 2019. Studies had to include at least 10 penicillin-allergic subjects whose allergy had been confirmed by a positive skin test (ST) or drug provocation test (DPT) result. Cross-reactivity had to be assessed to at least 1 cephalosporin or carbapenem through ST or DPT. Both random-effects and fixed-effect models were used to combine data. A bioinformatic model was used to quantify the similarity between R1 side chains. RESULTS: Twenty-one observational studies on cephalosporin cross-reactivity involving 1269 penicillin-allergic patients showed that the risk of cross-reactivity varied with the degree of similarity between R1 side chains: 16.45% (95% CI, 11.07-23.75) for aminocephalosporins, which share an identical side chain with a penicillin (similarity score = 1), 5.60% (95% CI, 3.46-8.95) for a few cephalosporins with an intermediate similarity score (range, 0.563-0.714), and 2.11% (95% CI, 0.98-4.46) for all those with low similarity scores (below 0.4), irrespective of cephalosporin generation. The higher risk associated with aminocephalosporins was observed whether penicillin allergy was IgE- or T-cell-mediated. Eleven observational studies on carbapenem cross-reactivity involving 1127 penicillin-allergic patients showed that the risk of cross-reactivity to any carbapenem was 0.87% (95% CI, 0.32-2.32). CONCLUSIONS: Although it remains possible that these meta-analyses overestimated the risk of cross-reactivity, clinicians should consider the increased risk of cross-reactivity associated with aminocephalosporins, and to a lesser extent with intermediate-similarity-score cephalosporins, compared with the very low risk associated with low-similarity-score cephalosporins and all carbapenems when using beta-lactams in patients with a suspected or proven penicillin allergy.

Ovarian Stimulation, Intrauterine Insemination, Multiple Pregnancy and Major Congenital Malformations: A Systematic Review and Meta- Analysis- The ART_Rev Study.

INTRODUCTION: Multiple pregnancies are a recognized adverse effect of assisted reproductive technologies; nevertheless, there is no consensus on the incremental risk associated with the ovarian stimulation (OS) used alone and intrauterine insemination (IUI). The relationship between OS and IUI and the risk of major congenital malformations (MCM) is unclear. OBJECTIVE: To summarise the literature and evaluate the risk of multiple pregnancy and MCM associated with OS used alone and IUI used with or without OS compared to natural conception (spontaneously conceived infants without any type of fertility treatments). METHODS: We carried out a systematic review to identify published papers between 1966 and 2014 in MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials. We included observational studies and randomized clinical trials related to the risk of multiple pregnancies and MCM conceived following OS alone or IUI compared to natural conception (spontaneously conceived infants without any fertility treatments). The quality of the included studies was evaluated using The Cochrane Collaboration's tool for assessing risk of bias for RCTs and the Newcastle-Ottawa Scale for observational studies. RESULTS: There were 63 studies included in this review. Our systematic review suggests that the use of any OS alone was associated with an increased risk of multiple pregnancy compared to natural conception (pooled RR 8.80, 95% CI 5.09- 15.20; p= 0.000; 9 studies). Similar increases in the risk of multiple pregnancies were observed following clomiphene citrate used without assisted reproductive technologies. Compared to natural conception, the use of IUI with or without OS was associated with an increased risk of multiple pregnancy (pooled RR 9.73, 95% CI 7.52 -12.60; p= 0.000; 6 studies). Compared to natural conception, the use of any OS alone was associated with an increased risk of any MCM (RR pooled 1.18, 95%CI 1.03-1.36; 11 studies), major musculoskeletal malformations (pooled RR 1.48, 95%CI 1.21-1.81; 7 studies), and malformations of the nervous system (pooled RR 1.73, 95%CI 1.15-2.61; 6 studies). Compared to natural conception, the use of IUI was associated with an increased risk of any MCM (pooled RR 1.23, 95%CI 1.10-1.37; 10 studies), major urogenital (pooled RR 1.52, 95%CI 1.04-2.22; 7 studies), and musculoskeletal malformations (pooled RR 1.54, 95%CI 1.20-1.98; 7 studies). The overall quality of the included studies was acceptable. CONCLUSIONS: The increased risk of multiple pregnancy and certain types of MCM associated with the use of less invasive fertility treatments, such as OS and IUI, found in this review, highlights the importance of the practice framing. Heterogeneity in OS protocols, the combination with other fertility agents, the limited number of studies and the methodological quality differences reduce our ability to draw conclusions on specific treatment. More observational studies, assessing the risk of multiple pregnancy or MCM, as a primary outcome, using standardized methodologies, in larger and better clinically defined populations are needed.

The ASQ and R-PDQ telephone-administered validation within the OTIS antidepressant in pregnancy study.

This study aimed to assess the telephone administration of the 12-month Ages and Stages Questionnaire (ASQ) and the 9- to 24-month Revised Prescreening Denver Questionnaire (R-PDQ) using the Antidepressants in Pregnancy Study cohort from the Organization of Teratology Information Specialists. The ASQ includes five domains (communication, gross motor, fine motor, problem-solving, and personal-social). The R-PDQ tests four areas of development (gross motor, fine motor, personal-social, and language). Both instruments were self and telephone-administered to mothers at 12 months postpartum. Concordance between the telephone and self-administration was assessed with intraclass correlation coefficients (ICCs) with 95% CIs. For the ASQ, concordance between test scores was substantial for the communication scale (ICC = 0.76, 95% CI [0.63, 0.85]), almost perfect for the gross motor scale (ICC = 0.83, 95% CI [0.73, 0.89]), and moderate for the fine motor, problem-solving, and personal-social scales (ICC = 0.43, 95% CI [0.19, 0.61]; ICC = 0.42, 95% CI [0.19, 0.61]; and ICC = 0.50, 95% CI [0.29, 0.67], respectively). Regarding the R-PDQ, concordance between test scores was as follows: gross motor (ICC = 0.90, 95% CI [0.83, 0.94]), language (ICC = 0.57, 95% CI [0.36, 0.73]), and personal-social scales (ICC = 0.26, 95% CI [0.00, 0.49]). For the fine motor scale, the correlation between both modes was 100%. The 12-month ASQ telephone administration could be an alternative for children developmental screening. Except the personal-social scale, the 9- to 24-month R-PDQ could be telephone-administered for prescreening development.
