Identifying hotspots of multidrug resistant tuberculosis transmission using spatial and molecular genetic data

 

The authors aimed to identify and determine the etiology of ‘hotspots’ of concentrated multi-drug resistant tuberculosis (MDR-TB) risk in Lima, Peru. Methods: From 2009-2012, we conducted a prospective cohort study among households of TB cases from 106 health center (HC) areas in Lima, Peru. All notified TB cases and their household contacts were recruited and followed for one year. Individuals with TB symptoms were screened by microscopy and culture; positive cultures were tested for drug susceptibility (DST) and genotyped by 24-loci MIRU-VNTR.

Findings reveal that localized transmission is an important driver of the epidemic of MDR-TB in Lima. Efforts to interrupt transmission may be most effective if targeted to this area of the city.

Health & Society Study of the Commodification of Hospital Care Published in the American Journal of Sociology

A study by Health & Society scholar Adam Reich was published in the American Journal of Sociology.  The “moralized markets” school within economic sociology has convincingly demonstrated variation in the relationship between economic activity and moral values. Yet this scholarship has not sufficiently explored either the causes of this variation or the consequences of this variation for organizational practice. By examining different moral-market understandings and practices in the context of a single market-based organizational field, this article highlights the contradictory character of processes of commodification, as different historically institutionalized ideas conflict, in different ways, with the market logic that increasingly organizes the field as a whole. The article examines the contradictory commodification of hospital care in three hospitals within one Northern California community.

RWJ-HSS Hosts Short Course On Graphical Models Nov 26 and 27
This course offers an applied introduction to the theory and practice of directed acyclic graphs (DAGs) for causal inference in the observational social and biomedical sciences. DAGs are rigorous tools for thinking carefully about complicated causal problems. The two primary uses of DAGs are (1) determining the identifiability of causal effects from observed data, and (2) deriving the testable implications of a causal model.
