Administrative healthcare data applied to fracture risk assessment.

Osteoporos Int 2018 Dec 15. Epub 2018 Dec 15.

Department of Community Health Sciences, University of Manitoba, Winnipeg, Manitoba, Canada.

Calcioic acid: In vivo detection and quantification of the terminal C24-oxidation product of 25-hydroxyvitamin D and related intermediates in serum of mice treated with 24,25-dihydroxyvitamin D.

J Steroid Biochem Mol Biol 2018 Dec 13. Epub 2018 Dec 13.

Department of Biomedical and Molecular Sciences, Queen's University, Kingston, ON, Canada. Electronic address:

Calcitroic acid, the excretory form of vitamin D, is the terminal product of a 5-step pathway catalyzed by CYP24A1, commencing with C24-hydroxylation of 1,25-dihydroxyvitamin D (1,25-(OH)D). Catabolism of 25-hydroxyvitamin D (25-OH-D) proceeds via analogous steps culminating in calcioic acid; however this C23-truncated acid has not been reported in the circulation. It has recently been shown that 24,25-dihydroxyvitamin D (24,25-(OH)D) is an important factor in optimal bone fracture healing acting via an effector molecule FAM57B2 to produce lactosylceramide.

Nanocellulose-based multilayer barrier coatings for gas, oil, and grease resistance.

Carbohydr Polym 2019 Feb 31;206:281-288. Epub 2018 Oct 31.

Department of Forest Biomaterials, North Carolina State University, Campus Box 8005, Raleigh, NC, 27695-8005, USA. Electronic address:

Cellulose derivatives such as cellulose nanofibers (CNF) and cellulose nanocrystals (CNC) have enormous potential to reduce or replace petroleum and fluorochemicals for food and other packaging applications. CNFs have been studied for their excellent oxygen and gas barrier properties; however, their performance rapidly decreases in the presence of moisture and higher humidity. CNCs are less sensitive to moisture due to their highly crystalline nature; however, coatings and films made of CNCs are much more prone to fracture due to their high brittleness. Read More

Cost-effectiveness analysis of total elbow arthroplasty versus open reduction-internal fixation for distal humeral fractures.

J Shoulder Elbow Surg 2019 Jan;28(1):102-111

Division of Sports Medicine, Midwest Orthopaedics at Rush, Rush University Medical Center, Chicago, IL, USA.

Background: Total elbow arthroplasty (TEA) and open reduction-internal fixation (ORIF) are 2 viable surgical treatment options for acute, intra-articular distal humeral fractures in elderly patients.

3D Imaging of Indentation Damage in Bone.

Henry Moseley X-ray Imaging Facility, Henry Royce Institute, School of Materials, The University of Manchester, Manchester M13 9PL, UK.

Bone is a complex material comprising high stiffness, but brittle, crystalline bio-apatite combined with compliant, but tough, collagen fibres. It can accommodate significant deformation, and the bone microstructure inhibits crack propagation such that micro-cracks can be quickly repaired. Catastrophic failure (bone fracture) is a major cause of morbidity, particularly in aging populations, either through a succession of small fractures or because a traumatic event is sufficiently large to overcome the individual crack blunting/shielding mechanisms.

Aim: To investigate the prevalence, location, and pattern of preexisting microcracks in non-endodontically treated teeth from fresh cadavers. Micro-computed tomography (micro-CT) technology was used as the analytical tool enabling full screening of the root dentine with the teeth retained in their original alveolar socket.

Methodology: As a pilot study and to validate the present method, a series of 4 high-resolution scans were performed on one bone-block specimen with teeth collected postmortem: (i) entire bone-block including the teeth, (ii) second molar tooth extracted atraumatically from the bone-block (iii) extracted tooth dehydrated to induce dentinal defects and (iv) entire bone-block following reinsertion of the extracted tooth into its matching alveolar socket.

Cracking and Fracture Properties of Potato (Solanum tuberosum L.) Tubers and Their Relation to Dry Matter, Starch, and Mineral Distribution.

J Sci Food Agric 2018 Dec 13. Epub 2018 Dec 13.

Department for Crop Sciences, Division Quality of Plant Products, Carl-Sprengel-Weg 1, 37075 Göttingen, University of Göttingen, Germany.

Background: Potato disorders lead to significant reductions in the yield and quality of marketable tubers. Thumbnail cracks are physiological tuber skin disorders that can significantly affect the tuber appearance and, hence, the overall quality. The aim of the study was to characterize fracture properties of the tuber skin. Read More

3T chemical shift-encoded MRI: Detection of altered proximal femur marrow adipose tissue composition in glucocorticoid users and validation with magnetic resonance spectroscopy.

J Magn Reson Imaging 2018 Dec 12. Epub 2018 Dec 12.

New York Langone Health, Department of Radiology, New York University School of Medicine, New York, New York, USA.

Background: Osteoporosis (OP) results in weak bone and can ultimately lead to fracture. Drugs such as glucocorticoids can also induce OP (glucocorticoid-induced osteoporosis [GIO]). Bone marrow adipose tissue composition and quantity may play a role in OP pathophysiology, but has not been thoroughly studied in GIO compared to primary OP. Read More

Relation of postoperative serum S100A12 levels to delirium and cognitive dysfunction occurring after hip fracture surgery in elderly patients.

Brain Behav 2018 Dec 11:e01176. Epub 2018 Dec 11.

Department of Anesthesia and Pain, The Affiliated Hangzhou First People's Hospital, Zhejiang University School of Medicine, Hangzhou, China.

Objective: Brain injury is implicated in pathogenesis of postoperative delirium (POD) and cognitive dysfunction (POCD). S100A12 is involved in inflammatory process and is recently known as a biomarker for brain injury. Herein, we clarified whether serum S100A12 levels are related to POD and POCD after hip fracture surgery in elderly patients. Read More

Epidemiology of Facial Fractures among Older Adults: A Retrospective Analysis of a Nationwide Emergency Department Database.

Dent Traumatol 2018 Dec 8. Epub 2018 Dec 8.

Department of Orthodontics, The University of Illinois in Chicago, Chicago, Illinois.

Background/aims: The prevalence of facial fractures among older adults has increased in recent years, and nationwide studies about the epidemiological profile and outcomes of hospital-based ED visits for facial fractures among older adults are scarce. The aim of this study was to provide USA-wide data of hospital-based Emergency Department (ED) visits for facial fractures among older adults, and to investigate the outcomes associated with these visits.

Material And Methods: The Nationwide Emergency Department Sample (NEDS) for the years 2008 to 2014 was used for the present study. Read More

Hindfoot Fusion Nail with Adjuvant Hybrid External Fixation used as Limb-Salvage Procedure after Failed Open Reduction Internal Fixation of Ankle Fracture in a Charcot Joint: A Case Report.

P R Health Sci J 2018 Dec;37(4):235-238

Department of Orthopedic Surgery, School of Medicine, University of Puerto Rico Medical Sciences Campus, San Juan, PR.

The failure of the internal fixation of an ankle fracture due to Charcot joint/ neuroarthropathy is rare; such occurred in the case of a 52-year-old woman with uncontrolled diabetes who sustained a right ankle fracture after falling from standing height. The patient was treated with the internal fixation of both malleoli, which procedure failed as the patient progressed, until she eventually was diagnosed with Charcot arthropathy. The post operative images were reviewed and showed a catastrophic fixation failure with a diagnosis of Charcot neuroarthropathy. Read More
