Prenatal Motivation for Caregiving Issues: A Pilot Study of Mothers Expecting Healthy Infants and Infants With Complex Congenital Heart Disease

Background and PurposeThe prenatal preparing women do for infant caregiving is understudied. In this pilot, multimethods study, we examined motivation for preparing for infant caregiving of women in their third trimester of pregnancy expecting either a healthy infant or an infant with complex congenital heart disease (CCHD).MethodsEleven women expecting a healthy infant and four expecting an infant with CCHD completed a questionnaire and were interviewed. Preparing was reported in context of expectations, intentions, and goals and in personal, family, and infant conditions. Motivation for preparing was expressed through an interview about caregiving issues women were working on. Intensity of motivation was estimated by self-report of the time infant caregiving issues were in thought or action. Effect sizes were calculated for between group differences in motivation intensity. Interview data were examined with directed content analysis.ResultsIntensity of motivation was higher for women expecting an infant with CCHD for issues of Knowing What and How to prepare. Women expecting an infant with CCHD reported uncertainty about how they would feed their babies given their health condition. Interviews yielded new motivations encompassing issues of family and working with the parent partner.ImplicationsAssessment of issues women are working on prenatally, indicating motivations for preparing for infant caregiving, and of the intensity of motivations advances culturally-attuned and family-centered preparation. Knowledge of these issues and motivation intensity could orient clinical care to supporting women in developing well-informed expectations, intentions, and goals culturally suited to postnatal learning and infant needs.

Intussusception in an Infant With SARS-CoV-2 Infection: A Case Report and a Review of the Literature

Coronavirus disease 2019 (COVID-19) is caused by acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Even if predominantly considered a respiratory pathogen, it could be associated with gastrointestinal involvement, generally in mild forms. Recent reports highlight the association between SARS-CoV-2 and intussusception in infants. A case of intussusception is hereby described in a previously healthy infant in whom the diagnosis of SARS-CoV-2 was made after the analysis of bronchoalveolar lavage and intraoperative specimens following surgical procedures. Accordingly, a review of infant cases with intussusception and SARS-CoV-2 infection is also reported.

Hundreds of viral families in the healthy infant gut

The gut microbiome (GM) is shaped through infancy and plays a major role in determining susceptibility to chronic inflammatory diseases later in life. Bacteriophages (phages) are known to modulate bacterial populations in numerous ecosystems, including the gut. However, virome data is difficult to analyse because it mostly consists of unknown viruses, i.e. viral dark matter. Here, we manually resolved the viral dark matter in the largest human virome study published to date. Fecal viromes from a cohort of 647 infants at 1 year of age were deeply sequenced and analysed through successive rounds of clustering and curation. We uncovered more than ten thousand viral species distributed over 248 viral families falling within 17 viral order-level clades. Most of the defined viral families and orders were novel and belonged to the Caudoviricetes viral class. Bacterial hosts were predicted for 79% of the viral species using CRISPR spacers, including those in metagenomes from the same fecal samples. While Bacteroides-infecting Crassphages were present, novel viral families were more predominant, including phages infecting Clostridiales and Bifidobacterium. Phage lifestyles were determined for more than three thousand caudoviral species. Lifestyles were homogeneous at the family level for 149 Caudoviricetes families, including 32 families that were found to be virulent, while 117 were temperate. Virulent phage families were more abundant but temperate ones were more diverse and widespread. Together, the viral families found in this study represent a major expansion of existing bacteriophage taxonomy.
