Fatal aortoesophageal fistula secondary to button battery ingestion in a young child
TL;DR: The importance of a high index of suspicion for battery ingestion in children, the need for clinicians to recognize a button battery on radiography, and the value of routine postmortem imaging in the detection of findings that may be relevant to the autopsy are highlighted.

Maize Productivity and Input Subsidies in Malawi: A State-Contingent Stochastic Production Frontier Approach
TL;DR: In this paper, the authors make cross-sectional comparisons of productivity in a risky agricultural setting and find that differences in productivity are mainly due to differences in environment and scale-mix efficiency.
Journal ArticleDOI

TL;DR: It is concluded that height may be an unrecognized but biologically plausible risk factor for several common conditions in adults and more studies are needed to reliably exclude horizontal pleiotropy as a driving force behind at least some of the MR associations observed in this study.
Journal ArticleDOI
Post-mortem CT lung findings at a medicolegal institute in SARS-CoV-2 RT-PCR positive cases with autopsy correlation.
TL;DR: In this paper, the authors explore the proposition that PMCT could be used as screening test for CoVID-19 pneumonia and show that even with positive swabs, clinical CoVID19 lung findings on PMCT are often not detected.

An Econometric Approach To Estimating Support Prices And Measures Of Productivity Change In Public Hospitals
TL;DR: In this article, the authors use linear programming to construct a quantity index and use this approach to estimate productivity indexes and support (or shadow) prices for a sample of Australian public hospitals, finding that the productivity effects of improvements in input-oriented technical efficiency have been largely offset by the effects of deteriorations in the production environment over time.
