The postnatal effects of perineal trauma on maternal psychological and emotional wellbeing: A longitudinal study.

Objective: To examine the postnatal psychological health and parenting adjustment of primiparous women experiencing perineal trauma.

Study Design: Longitudinal cohort study assessing body image, perceptions of traumatic birth, psychological distress, perineal pain, impact upon parental tasks and mother-infant bonding at 6-12 weeks (n = 103) and 6-10 months postnatally (n = 91). Primiparous women were recruited following vaginal birth and perineal suturing in a UK-based maternity hospital.

The effects of perineal trauma on immediate self-reported birth experience in first-time mothers.

Introduction: Childbirth can sometimes be stressful or traumatic, and previous research has considered how birth complications and interventions may contribute to a negative birth experience. One of the most frequent complications during birth is trauma to the perineum. The aim of this study was to investigate whether different levels of perineal trauma were associated with differences in women's evaluation of their birth experience.

Genome-Based Infection Tracking Reveals Dynamics of Clostridium difficile Transmission and Disease Recurrence.

Background: Accurate tracking of Clostridium difficile transmission within healthcare settings is key to its containment but is hindered by the lack of discriminatory power of standard genotyping methods. We describe a whole-genome phylogenetic-based method to track the transmission of individual clones in infected hospital patients from the epidemic C. difficile 027/ST1 lineage, and to distinguish between the 2 causes of recurrent disease, relapse (same strain), or reinfection (different strain).

The N170 observed 'in the wild': robust event-related potentials to faces in cluttered dynamic visual scenes.

As a social species in a constantly changing environment, humans rely heavily on the informational richness and communicative capacity of the face. Thus, understanding how the brain processes information about faces in real-time is of paramount importance. The N170 is a high-temporal resolution electrophysiological index of the brain's early response to visual stimuli that is reliably elicited in carefully controlled laboratory-based studies.
