Analysis of the medical residency matching algorithm to validate and improve equity

Plos.org 

by Briance Mascarenhas, Kartikeye Puranam

Algorithms are becoming prevalent but are often opaque and need external validation to assess whether or not they meet their purported objectives. The purpose of this study is to validate, using the limited information available, the algorithm used by the National Resident Matching Program (NRMP) whose intention is to match applicants to medical residencies based on applicants’ prioritized preferences. The methodology involved first using randomized... Читать дальше...



Coupling analysis of heart rate variability and cortical arousal using a deep learning algorithm

Plos.org 

by Jiayan Huo, Stuart F. Quan, Janet Roveda, Ao Li

Frequent cortical arousal is associated with cardiovascular dysfunction among people with sleep-disordered breathing. Changes in heart rate variability (HRV) can represent pathological conditions associated with autonomic nervous system dysfunction. Previous studies showed changes in cardiac activity due to cortical arousals. However, few studies have examined the instantaneous association between cortical arousal and HRV in an ethnically diverse population. Читать дальше...

Does a mother’s childbirth experience influence her perceptions of her baby’s behaviour? A qualitative interview study

Plos.org 

by Carmen Power, Claire Williams, Amy Brown

Background

Childbirth has become increasingly medicalised, which may impact on the mother’s birth experience and her newborn infant’s physiology and behaviour. Although associations have been found between a mother’s subjective birth experience and her baby’s temperament, there is limited qualitative evidence around how and why this may occur.

Objectives

This qualitative study aimed to explore mothers’ childbirth and postnatal experiences... Читать дальше...

Human and pathogen genotype-by-genotype interactions in the light of coevolution theory

Plos.org 

by Lars Råberg

Antagonistic coevolution (i.e., reciprocal adaptation and counter-adaptation) between hosts and pathogens has long been considered an important driver of genetic variation. However, direct evidence for this is still scarce, especially in vertebrates. The wealth of data on genetics of susceptibility to infectious disease in humans provides an important resource for understanding host–pathogen coevolution, but studies of humans are rarely framed in coevolutionary theory. Here... Читать дальше...

The defense island repertoire of the Escherichia coli pan-genome

Plos.org 

by Dina Hochhauser, Adi Millman, Rotem Sorek

It has become clear in recent years that anti-phage defense systems cluster non-randomly within bacterial genomes in so-called “defense islands”. Despite serving as a valuable tool for the discovery of novel defense systems, the nature and distribution of defense islands themselves remain poorly understood. In this study, we comprehensively mapped the defense system repertoire of >1,300 strains of Escherichia coli, the most widely studied organism for phage-bacteria interactions. Читать дальше...

Pleiotropy promotes the evolution of inducible immune responses in a model of host-pathogen coevolution

Plos.org 

by Reese A. Martin, Ann T. Tate

Components of immune systems face significant selective pressure to efficiently use organismal resources, mitigate infection, and resist parasitic manipulation. A theoretically optimal immune defense balances investment in constitutive and inducible immune components depending on the kinds of parasites encountered, but genetic and dynamic constraints can force deviation away from theoretical optima. One such potential constraint is pleiotropy, the phenomenon... Читать дальше...

Delayed skeletal muscle repair following inflammatory damage in simulated agent-based models of muscle regeneration

Plos.org 

by Stephanie Khuu, Justin W. Fernandez, Geoffrey G. Handsfield

Healthy skeletal muscle undergoes repair in response to mechanically localised strains during activities such as exercise. The ability of cells to transduce the external stimuli into a cascade of cell signalling responses is important to the process of muscle repair and regeneration. In chronic myopathies such as Duchenne muscular dystrophy and inflammatory myopathies, muscle is often subject to chronic necrosis and inflammation... Читать дальше...
