Analysis of femurs from mice embarked on board BION-M1 biosatellite reveals a decrease in immune cell development, including B cells, after 1 wk of recovery on Earth.

FASEB J 2018 Dec 6:fj201801463R. Epub 2018 Dec 6.

Centre National de la Recherche Scientifique (CNRS), Institut Pluridisciplinaire Hubert Curien (IPHC) Unité Mixte de Recherche (UMR) 7178, Université de Strasbourg, Strasbourg, France.

Bone loss and immune dysregulation are among the main adverse outcomes of spaceflight challenging astronaut's health and safety. However, consequences on B-cell development and responses are still under-investigated. To fill this gap, we used advanced proteomics analysis of femur bone and marrow to compare mice flown for 1 mo on board the BION-M1 biosatellite, followed or not by 1 wk of recovery on Earth, to control mice kept on Earth.

Medullary bone in an Early Cretaceous enantiornithine bird and discussion regarding its identification in fossils.

Nat Commun 2018 Dec 5;9(1):5169. Epub 2018 Dec 5.

Key Laboratory of Vertebrate Evolution and Human Origins of Chinese Academy of Sciences, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, 100044, Beijing, China.

Medullary bone is an ephemeral type of bone tissue, today found only in sexually mature female birds, that provides a calcium reservoir for eggshell formation. The presence of medullary bone-like tissues in extant birds, pterosaurs, and dinosaurs distantly related to birds shows that caution must be exercised before concluding that fossils bear medullary bone. Here we describe a new specimen of pengornithid enantiornithine from the Lower Cretaceous Jiufotang Formation. Read More

Orthopaedics and Trauma Unit, Emergency Department, Ospedale Policlinico San Martino, Largo R. Benzi 10-16132, Genoa, Italy.

Septic nonunion is one of the most serious complications after an open fracture because both the infection and the bone defect need to be dealt with. Treatment is always protracted and expensive, and the result is uncertain. In the 1980s, Masquelet first described the technique of the induced membrane and autologous bone grafting to manage critical bone defects. Read More

[Women with groin hernias should be referred to surgery].

Ugeskr Laeger 2018 Nov;180(48)

In females, approximately 75% of groin hernias are inguinal hernias, and 25% are femoral. However, all groin hernias in women should be considered potential femoral hernias due to the difficult preoperative diagnosis of hernia type and the high incidence of femoral hernias. Complications following an untreated femoral hernia are unacceptable, which is why, watchful waiting is not recommended in women. Read More

Do dGEMRIC and T2 Imaging Correlate With Histologic Cartilage Degeneration in an Experimental Ovine FAI Model?

Clin Orthop Relat Res 2018 Nov 29. Epub 2018 Nov 29.

F. Schmaranzer, E. F. Liechti, M. Tannast, Department of Orthopaedic Surgery, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland L. Arendt, K. Nuss, B. von Rechenberg, M. Tannast, Musculoskeletal Research Unit (MSRU), Equine Hospital, Vetsuisse Faculty, University of Zürich, Zürich, Switzerland P. R. Kircher, Department of Small Animals, Division of Diagnostic Imaging, Vetsuisse Faculty, University of Zürich, Zürich, Switzerland.

Background: Biochemical MRI of hip cartilage such as delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) and T2 mapping is increasingly used to judge cartilage quality in the assessment of femoroacetabular impingement (FAI). The current evidence is sparse about which of these techniques yields a stronger correlation with histologic cartilage degeneration because of the difficulty in validating biochemical MRI techniques against histology in the clinical setting. Recently, an experimental ovine FAI model was established that induces chondrolabral damage and offers a validated platform to address these limitations. Read More

Background: Nonoperative management for blunt splenic injury is the preferred treatment. To improve the outcome of selective nonoperative therapy, the current challenge is to identify factors that predict failure. Little is known about the impact of concomitant injury on outcome. Read More

Probability of At Least One High Arterial Blood Pressure Measurement in Elderly Patients with Healthy Vascular Aging in Two Years of Follow-Up.

Kidney Blood Press Res 2018 Nov 30;43(6):1765-1771. Epub 2018 Nov 30.

Background/aims: Elderly patients with normal systemic arterial blood pressure associated with femoral carotid pulse velocity (cf-PWV) less than 7.6 m/s and without associated comorbidities are considered to have good vascular health. The aim of the current study was to verify the probability that elderly patients with good vascular health have at least one blood pressure measurement above the different thresholds for systolic blood pressure (120, 130 and 140 mmHg) during two years of follow-up.

Outcomes of Extracorporeal Membrane Oxygenation Support for Complex High-Risk Elective Percutaneous Coronary Interventions: A Single-Center Experience and Review of the Literature.

J Invasive Cardiol 2018 Dec;30(12):456-460

Minneapolis Heart Institute, 920 E. 28th Street #300, Minneapolis, MN 55407 USA.

Objectives: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is most commonly used in patients with cardiac arrest and cardiogenic shock. There are limited data on the use of VA-ECMO for elective, high-risk percutaneous coronary intervention (PCI). We examined the in-hospital and mid-term clinical outcomes in patients undergoing complex, high-risk PCI with VA-ECMO support. Read More

Progressive Sublesional Bone Loss Extends into the Second Decade After Spinal Cord Injury.

J Clin Densitom 2018 Oct 31. Epub 2018 Oct 31.

Department of Veterans Affairs Rehabilitation Research & Development Service National Center for the Medical Consequences of Spinal Cord Injury, James J. Peters Veterans Affairs Medical Center, Bronx, NY, USA; Departments of Medicine and Rehabilitation Medicine, Icahn School of Medicine at Mount Sinai, New York, NY, USA.

Objective: The rate of areal bone mineral density (aBMD) loss at the knee (distal femur (DF) and proximal tibia ) and hip (femoral neck (FN) and total hip (TH)) was determined in persons with traumatic spinal cord injury (SCI) who were stratified into subgroups based on time since injury (TSI).

Design: Cross-sectional retrospective review.

Setting: Department of Veterans Affairs Medical Center and Private Rehabilitation Hospital. Read More

Cortical and trabecular bone microarchitecture as an independent predictor of incident fracture risk in older women and men in the Bone Microarchitecture International Consortium (BoMIC): a prospective study.

Lancet Diabetes Endocrinol 2018 Nov 28. Epub 2018 Nov 28.

Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA, USA; Department of Orthopedic Surgery, Harvard Medical School, Center for Advanced Orthopedic Studies, Beth Israel Deaconess Medical Center, Boston, MA, USA.

Background: Although areal bone mineral density (aBMD) assessed by dual-energy x-ray absorptiometry (DXA) is the clinical standard for determining fracture risk, most older adults who sustain a fracture have T scores greater than -2·5 and thus do not meet the clinical criteria for osteoporosis. Importantly, bone fragility is due to low BMD and deterioration in bone structure. We assessed whether indices of high-resolution peripheral quantitative CT (HR-pQCT) were associated with fracture risk independently of femoral neck aBMD and the Fracture Risk Assessment Tool (FRAX) score.

WIRION EPS filter with jetstream atherectomy of femoropopliteal arterial disease: A single center experience.

Cardiovasc Revasc Med 2018 Nov 16. Epub 2018 Nov 16.

Midwest Cardiovascular Research Foundation, Davenport, IA, United States of America.

Background: The WIRION EPS filter was recently approved by the Food and Drug Administration (FDA) to be used in conjunction with all atherectomy devices when treating infrainguinal peripheral arterial disease. The safety of this filter with Jetstream atherectomy (JA) in a real world setting remains unclear.

Methods: Consecutive patients from the practice of one operator who underwent JA under WIRION EPS when treating femoropopliteal arteries were enrolled in this retrospective analysis. Read More
