Association of ionizing radiation dose from common medical diagnostic procedures and lymphoma risk in the Epilymph case-control study.

PLoS One 2020 10;15(7):e0235658. Epub 2020 Jul 10.

CIBER Epidemiología y Salud Pública (CIBERESP), Madrid, Spain.

Medical diagnostic X-rays are an important source of ionizing radiation (IR) exposure in the general population; however, it is unclear if the resulting low patient doses increase lymphoma risk. We examined the association between lifetime medical diagnostic X-ray dose and lymphoma risk, taking into account potential confounding factors, including medical history. The international Epilymph study (conducted in the Czech-Republic, France, Germany, Ireland, Italy, and Spain) collected self-reported information on common diagnostic X-ray procedures from 2,362 lymphoma cases and 2,465 frequency-matched (age, sex, country) controls.

Correlation of 3D Joint Space Width From Weightbearing CT With Outcomes After Intra-articular Calcaneal Fracture.

Foot Ankle Int 2020 Jul 10:1071100720933891. Epub 2020 Jul 10.

Department of Orthopedics and Rehabilitation, University of Iowa, Iowa City, IA, USA.

Background: Posttraumatic osteoarthritis (PTOA) of the subtalar joint is a serious, disabling, and frequent complication following intra-articular calcaneal fractures (IACFs). Using plain radiographs to assess the subtalar joint for PTOA is imprecise and insensitive, hindering progress toward improving treatment and assessing outcomes. This study explored how low-dose weightbearing computed tomography (WBCT) can be used to provide reliable, quantitative 3D measures of subtalar joint space width (JSW) following IACF and correlated the 3D JSW with clinical outcomes.

Multivariable logistic and linear regression models for identification of clinically useful biomarkers for osteoarthritis.

Sci Rep 2020 Jul 9;10(1):11328. Epub 2020 Jul 9.

Translational Health Sciences, Bristol Medical School, Musculoskeletal Research Unit, Southmead Hospital, University of Bristol, Learning and Research Building (Level 2), Bristol, BS10 5NB, UK.

Osteoarthritis (OA) is the most common chronic degenerative joint disease which causes substantial joint pain, deformity and loss of activities of daily living. Currently, there are over 500 million OA cases worldwide, and there is an urgent need to identify biomarkers for early detection, and monitoring disease progression in patients without obvious radiographic damage to the joint. We have used regression modelling to describe the association of 19 of the currently available biomarkers (predictors) with key radiographic and clinical features of OA (outcomes) in one of the largest and best characterised OA cohort (NIH Osteoarthritis Initiative).

LDHA-mediated ROS generation in chondrocytes is a potential therapeutic target for osteoarthritis.

Nat Commun 2020 Jul 9;11(1):3427. Epub 2020 Jul 9.

Department of Orthopaedic Surgery and Cell Biology & Physiology, Washington University School of Medicine, St. Louis, MO, 63110, USA.

The contribution of inflammation to the chronic joint disease osteoarthritis (OA) is unclear, and this lack of clarity is detrimental to efforts to identify therapeutic targets. Here we show that chondrocytes under inflammatory conditions undergo a metabolic shift that is regulated by NF-κB activation, leading to reprogramming of cell metabolism towards glycolysis and lactate dehydrogenase A (LDHA). Inflammation and metabolism can reciprocally modulate each other to regulate cartilage degradation. Read More

A 10-year experience with reverse shoulder arthroplasty: are we operating earlier?

J Shoulder Elbow Surg 2020 Jul;29(7S):S126-S133

Department of Orthopedic Surgery, Mayo Clinic, Jacksonville, FL, USA. Electronic address:

Introduction: As surgeons' confidence in reverse shoulder arthroplasty (RSA) increases, they may tend to offer RSA earlier in the course of glenohumeral joint disease. This study evaluates the changes in the "tipping point" for primary RSA over a 10-year period to evaluate changes in practice.

Methods: A total of 3975 primary RSAs performed over a 10-year period were retrospectively reviewed from a multi-institutional database. Read More

Acceptable outcomes with unicompartmental knee replacement and PCL deficiency are achievable: a case series of nine patients.

Knee Surg Sports Traumatol Arthrosc 2020 Jul 8. Epub 2020 Jul 8.

Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences, University of Oxford, Oxford, OX3 7LD, UK.

Purpose: Posterior cruciate ligament (PCL) deficiency is considered to be a contraindication for unicompartmental knee replacement (UKR); however, there is no evidence to support or contradict this. There are occasional circumstances where UKR in PCL deficient patients have been performed where the patient otherwise satisfies the indications for UKR. The aim of this paper is to describe the outcome of UKR in PCL deficient patients. Read More
