Genital mycoplasmas, which can be vertically transmitted, have been implicated in preterm birth, neonatal infections, and chronic lung disease of prematurity. Our prior work uncovered 16S rRNA genes belonging to a novel, as-yet-uncultivated mycoplasma (lineage 'Mnola') in the oral cavity of a premature neonate. Here, we characterize the organism's associated community, growth status, metabolic potential, and population diversity. Sequencing of genomic DNA from the infant's saliva yielded 1.44 Gbp of high-quality, non-human read data, from which we recovered three essentially complete (including 'Mnola') and three partial draft genomes (including Trichomonas vaginalis). The completed 629,409-bp 'Mnola' genome (Candidatus Mycoplasma girerdii str. UC-B3) was distinct at the strain level from its closest relative, vaginally-derived Ca. M. girerdii str. VCU-M1, which is also associated with T. vaginalis. Replication rate measurements indicated growth of str. UC-B3 within the infant. Genes encoding surface-associated proteins and restriction-modification systems were especially diverse within and between strains. In UC-B3, the population genetic underpinnings of phase variable expression were evident in vivo. Unique among mycoplasmas, Ca. M. girerdii encodes pyruvate-ferredoxin oxidoreductase and may be sensitive to metronidazole. This study reveals a metabolically unique mycoplasma colonizing a premature neonate, and establishes the value of genome-resolved metagenomics in tracking phase variation.

Objectives: Many children undergo surgery or an invasive procedure during their terminal hospital admission. 1 The types of procedures, patients, and the intent of the procedures has not been well defined. Understanding these details may help pediatric surgeons better determine the clinical settings in which certain procedures will not enhance palliation or survival. Methods: A retrospective single institution chart review was performed for patients age 14 days to 18 years with chronic conditions who died while inpatient from 2013–2017. Data was gathered on demographics, primary diagnosis, intubation status, palliative care involvement, duration of hospital stay, length of palliative care involvement, and total number of procedures. Negative binomial regression was used to assess association with number of procedures. Results: 132 children met inclusion criteria. Most children were White and less than one year old. The most common type of diagnosis was cardiac in nature. Children underwent an average of three procedures. 75% were intubated and 77.5% had palliative care involved. Patients who were less than one year old at death were more likely to have been intubated, had longer terminal hospital stays, and had more procedures. Those who were intubated underwent more procedures and had longer hospital stays. Those with longer palliative care involvement had fewer procedures. Conclusions: Children undergo a significant number of surgical procedures during their terminal hospitalization. This may be influenced by age, intubation status, and length of stay. Ongoing study may help refine which procedures may have limited impact on survival in the chronically ill pediatric population. [ABSTRACT FROM AUTHOR]

Introduction: Shared decision‐making, with an emphasis on patient autonomy, is often advised in healthcare decision‐making. However, this may be difficult to implement in emergent settings. We have previously demonstrated that when considering emergent operations for their children, parents prefer surgeon guidance as opposed to shared decision‐making. Here, we interviewed parents of paediatric patients who had undergone emergent operations to better understand parental decision‐making preferences. Methods: Parents of paediatric patients who underwent surgery over the past 5 years at a University‐based, tertiary children's hospital for cancer, an emergent operation while in the neonatal intensive care unit (NICU) or extracorporeal membrane oxygenation (ECMO) were invited to complete a 60‐min semi‐structured interview. Interviews were digitally recorded and transcribed verbatim. Thematic content analysis was performed via deductive and inductive analysis. An iterative approach to thematic sampling/data analysis was used. Results: Thematic saturation was achieved after 12 interviews (4 cancer, 5 NICU and 3 ECMO). Five common themes were identified: (1) recommendations from surgeons are valuable; (2) 'lifesaving mode': parents felt there were no decisions to be made; (3) effective ways of obtaining information about treatment; (4) shared decision‐making as a 'dialogue' or 'discussion' and (5) parents as a 'valued voice' to advocate for their children. Conclusions: When engaging in decision‐making regarding emergent surgical procedures for their children, parents value a surgeon's recommendation. Parents felt that discussion or dialogue with surgeons defined shared decision‐making, and they believed that the opportunity to ask questions gave them a 'valued voice', even when they felt there were no decisions to be made. Patient or Public Contribution: For this study, we interviewed parents of paediatric patients who had undergone emergent operations to better understand parental decision‐making preferences. Parents thus provided all the data for the study. [ABSTRACT FROM AUTHOR]
