E-Cigarettes, Vaping Devices, and Acute Lung Injury.

Respir Care 2020 May;65(5):713-718

Division of Pulmonary and Critical Care, Department of Medicine, Georgetown University School of Medicine, Washington, District of Columbia.

"E-cigarettes" are a class of consumer devices designed to deliver drugs, primarily nicotine or marijuana oils, to the lung by vaporization. Regulation of the devices in the United States is relatively minimal, and research on both epidemiology and potential toxicity has focused on nicotine devices. In 2019, an outbreak of an acute respiratory illness in the United States was traced back to the contamination of e-cigarette fluids with vitamin E acetate, which had been used to disguise the dilution of marijuana oils.

Identification of a limb enhancer that is removed by pathogenic deletions downstream of the SHOX gene.

Sci Rep 2018 09 24;8(1):14292. Epub 2018 Sep 24.

Department of Biological Sciences, University of Calgary, 2500 University Drive N.W., Calgary, Alberta, T2N 1N4, Canada.

Haploinsufficiency of the human SHOX gene causes Léri-Weill dyschondrosteosis (LWD), characterized by shortening of the middle segments of the limbs and Madelung deformity of the wrist. As many as 35% of LWD cases are caused by deletions of non-coding sequences downstream of SHOX that presumably remove an enhancer or enhancers necessary for SHOX expression in developing limbs. We searched for these active sequences using a transgenic mouse assay and identified a 563 basepair (bp) enhancer with specific activity in the limb regions where SHOX functions. Read More

Kinematic alignment technique for total hip and knee arthroplasty: The personalized implant positioning surgery.

EFORT Open Rev 2018 Mar 29;3(3):98-105. Epub 2018 Mar 29.

MSK Lab, Imperial College London, UK.

Conventional techniques for hip and knee arthroplasty have led to good long-term clinical outcomes, but complications remain despite better surgical precision and improvements in implant design and quality.Technological improvements and a better understanding of joint kinematics have facilitated the progression to 'personalized' implant positioning (kinematic alignment) for total hip (THA) and knee (TKA) arthroplasty, the true value of which remains to be determined.By achieving a true knee resurfacing, the kinematic alignment (KA) technique for TKA aims at aligning the components with the physiological kinematic axes of the knee and restoring the constitutional tibio-femoral joint line frontal and axial orientation and soft-tissue laxity.

Spine-hip relations in patients with hip osteoarthritis.

EFORT Open Rev 2018 Feb 21;3(2):39-44. Epub 2018 Feb 21.

London Hip Unit, UK.

Patients with hip osteoarthritis often have an abnormal spine-hip relation (SHR), meaning the presence of a clinically deleterious spine-hip and/or hip-spine syndrome.Definition of the individual SHR is ideally done using the EOS® imaging system or, if not available, with conventional lumbopelvic lateral radiographs.By pre-operatively screening patients with abnormal SHR, it is possible to refine total hip replacement (THR) surgical planning, which may improve outcomes.

Radically truncated MeCP2 rescues Rett syndrome-like neurological defects.

Nature 2017 10 11;550(7676):398-401. Epub 2017 Oct 11.

The Wellcome Centre for Cell Biology, University of Edinburgh, Michael Swann Building, King's Buildings, Max Born Crescent, Edinburgh EH9 3BF, UK.

Heterozygous mutations in the X-linked MECP2 gene cause the neurological disorder Rett syndrome. The methyl-CpG-binding protein 2 (MeCP2) protein is an epigenetic reader whose binding to chromatin primarily depends on 5-methylcytosine. Functionally, MeCP2 has been implicated in several cellular processes on the basis of its reported interaction with more than 40 binding partners, including transcriptional co-repressors (for example, the NCoR/SMRT complex), transcriptional activators, RNA, chromatin remodellers, microRNA-processing proteins and splicing factors.

Overlapping genetic pathways in the skeletal dysplasias of a middle woodland individual: A case study.

Int J Paleopathol 2017 09 21;18:98-107. Epub 2017 Jun 21.

Department of Anthropology and Middle Eastern Cultures/Cobb Institute of Archaeology, Mississippi State University, P.O. Box AR, MS, 39762, USA. Electronic address:

Studies of interacting/overlapping genetic skeletal disorders are rare for populations today, but even more so for archaeological contexts. The skeletal remains of an adult female (EZ 3-7-1) were excavated in the 1980s from the Middle Woodland (50BC-AD400) context of the Elizabeth site (11PK512) in the lower Illinois Valley (LIV), USA. Reported here are the standard score (z-score) comparisons of the measured skeletal differences of EZ 3-7-1 with a reference sample and a re-analysis of the individual's pathological changes, with special consideration placed on refining the disease diagnosis.
