Hyponatremia Is Associated With Increased Osteoporosis and Bone Fractures in Patients With Diabetes With Matched Glycemic Control.

J Endocr Soc 2019 Feb 4;3(2):411-426. Epub 2019 Jan 4.

Division of Endocrinology and Metabolism, Georgetown University Medical Center, Washington, District of Columbia.

Context: Patients with diabetes mellitus are at increased risk for bone fragility fracture secondary to multiple mechanisms. Hyperglycemia can induce true dilutional hyponatremia. Hyponatremia is associated with gait instability, osteoporosis, and increased falls and bone fractures, and studies suggest that compromised bone quality with hyponatremia may be independent of plasma osmolality.

Bone Status in Obese, Non-diabetic, Antipsychotic-Treated Patients, and Effects of the Glucagon-Like Peptide-1 Receptor Agonist Exenatide on Bone Turnover Markers and Bone Mineral Density.

Front Psychiatry 2018 28;9:781. Epub 2019 Jan 28.

Mental Health Centre Glostrup, Copenhagen University Hospital, Glostrup, Denmark.

Low bone mineral density (BMD) may constitute an underestimated comorbidity in schizophrenia patients undergoing long-term antipsychotic treatment. Glucagon-like peptide 1 (GLP-1) receptor agonists are antidiabetic drugs, which may also affect bone turnover. In planned secondary analyses of a 3 months, double-blind, randomized, placebo-controlled trial ( = 45), we explored effects of the GLP-1 receptor agonist exenatide 2 mg once-weekly ( = 23), or placebo ( = 22) on bone turnover markers (BTMs) and BMD in chronic, obese, antipsychotic-treated patients with schizophrenia spectrum disorder.

Accuracy of FRAX® in people with multiple sclerosis.

J Bone Miner Res 2019 Jan 28. Epub 2019 Jan 28.

Departments of Internal Medicine (Endocrinology) and Radiology (Nuclear Medicine), Max Rady College of Medicine, Rady Faculty of Health Sciences, Winnipeg, Manitoba, Canada.

People with multiple sclerosis (MS) have a higher risk of low bone mineral density (BMD), osteoporosis, and osteoporotic fractures than healthy adults. The Fracture Risk Assessment tool (FRAX®) has been reported to underestimate fracture risk in people with MS when BMD is unknown. We tested FRAX performance for people with MS when BMD is known, and determined if MS is a risk factor for fracture independent of FRAX score. Read More

MicroRNA and Human Bone Health.

JBMR Plus 2019 Jan 5;3(1):2-13. Epub 2018 Nov 5.

Department of Pharmacology and Pharmacy The University of Hong Kong Pokfulam Hong Kong.

The small non-coding microRNAs (miRNAs) are post-transcription regulators that modulate diverse cellular process in bone cells. Because optimal miRNA targeting is essential for their function, single-nucleotide polymorphisms (SNPs) within or proximal to the loci of miRNA (miR-SNPs) or mRNA (PolymiRTS) could potentially disrupt the miRNA-mRNA interaction, leading to changes in bone metabolism and osteoporosis. Recent human studies of skeletal traits using miRNA profiling, genomewide association studies, and functional studies started to decipher the complex miRNA regulatory network. Read More

Sost haploinsufficiency provokes peracute lethal cardiac tamponade without rescuing the osteopenia in a mouse model of excess glucocorticoids.

Am J Pathol 2019 Jan 18. Epub 2019 Jan 18.

Department of Comparative Biomedical Sciences, The Royal Veterinary College, London, United Kingdom.

Glucocorticoid-induced secondary osteoporosis is the most predictable side-effect of this anti-inflammatory. One of the main mechanisms by which glucocorticoids achieve such deleterious outcome in bone is by antagonizing Wnt/β-catenin signalling. Sclerostin, encoded by Sost gene, is the main negative regulator of the pro-formative and anti-resorptive role of the Wnt signaling pathway in the skeleton. Read More

Changes in middle ear transmission characteristics secondary to altered bone remodelling.

Osteoporos Int 2019 Jan 16. Epub 2019 Jan 16.

Department of Audiology, All India Institute of Speech and Hearing, Manasagangothri, Mysore, Karnataka, 570006, India.

Alteration in the process of bone remodelling results in conditions like osteopenia and osteoporosis in which the bones become susceptible to fracture. The functioning of middle ear bones in such individuals were assessed in this study and it was found that the middle ear bones are equally susceptible to micro-fractures and can cause reduction in the transmission of sound energy.

Introduction: Alteration in the process of bone remodelling or increase in the number of osteoclasts cells as it occurs in osteoporosis and osteopenia are likely to affect the middle ear bones in the same way it affects the skeletal bones. Read More

Effect of a Fracture Liaison Service on the Rate of Subsequent Fracture Among Patients With a Fragility Fracture in the Norwegian Capture the Fracture Initiative (NoFRACT): A Trial Protocol.

JAMA Netw Open 2018 Dec 7;1(8):e185701. Epub 2018 Dec 7.

Department of Clinical Medicine, Arctic University of Norway, Tromsø, Norway.

Importance: Fragility fracture is a major health issue because of the accompanying morbidity, mortality, and financial cost. Despite the high cost to society and personal cost to affected individuals, secondary fracture prevention is suboptimal in Norway, mainly because most patients with osteoporotic fractures do not receive treatment with antiosteoporotic drugs after fracture repair.

Objectives: To improve secondary fracture prevention by introducing a standardized intervention program and to investigate the effect of the program on the rate of subsequent fractures. Read More

Polymethylmethacrylate-augmented fenestreted pedicle-screw fixation in low bone quality patients: a case series and literature review.

J Biol Regul Homeost Agents 2018 Nov-Dec;32(6 Suppl. 1):71-76

Department of Oncologic and Degenerative Spine Surgery, IRCCS Istituto Ortopedico Rizzoli - Bologna, Italy.

The use of pedicle screws in low bone quality patients implicates risks of secondary implant loosening for grip lack. In fact, the result is a reduced mechanical stability at bone-screw interface and consequently an increased chance of pullout and hardware failure. Augmentation techniques have been described for many years and fenestrated screws that allow cement injection is one of them. Read More

Introduction: Recent meta-analyses have found a correlation between schizophrenia and increased fracture risk with one contributing factor potentially being antipsychotic-induced hyperprolactinemia, which may accelerate bone turnover. The objective of this study is to evaluate fracture rates in patients on long-term antipsychotic therapy to see if screening for osteoporosis should be included with routine monitoring.

Methods: Patients exposed to antipsychotics for ≥3 months during a 10-year study period were included in this retrospective analysis. Read More

MANAGEMENT OF ENDOCRINE DISEASE: Diagnosis and management of the patient with non-classic CAH due to 21-hydroxylase deficiency.

Eur J Endocrinol 2018 Dec 1. Epub 2018 Dec 1.

H Falhammar, Depatment of Endocrinology, Metabolism and Diabetes, Karolinska Universitetssjukhuset, Stockholm, 171 76, Sweden.

Non-classic congenital adrenal hyperplasia (NCAH) is a relatively common disorder regardless of ethnicity, but most cases are never diagnosed, especially in males. A baseline 17-hydroxyprogesterone measurement may be used for screening, but 17-hydroxyprogesterone measurement after ACTH-stimulation is the gold standard. We advocate a CYP21A2 mutation analysis to verify the diagnosis, for genetic counselling and for better prognostic and treatment guidance. Read More

Detection of Osteoporosis from Percussion Responses Using an Electronic Stethoscope and Machine Learning.

Bioengineering (Basel) 2018 Dec 5;5(4). Epub 2018 Dec 5.

Taybank Medical Centre, 10 Robertson Street, Dundee, DD4 6EL, UK.

Osteoporosis is an asymptomatic bone condition that affects a large proportion of the elderly population around the world, resulting in increased bone fragility and increased risk of fracture. Previous studies had shown that the vibroacoustic response of bone can indicate the quality of the bone condition. Therefore, the aim of the authors' project is to develop a new method to exploit this phenomenon to improve detection of osteoporosis in individuals. Read More

Bone biopsy in nephrology practice.

J Bras Nefrol 2018 Oct-Dec;40(4):366-374. Epub 2018 Nov 29.

Universidade de São Paulo, Faculdade de Medicina, Hospital das Clinicas, Laboratório de Fisiopatologia Renal São Paulo, SP, Brasil.

Renal osteodystrophy (ROD), a group of metabolic bone diseases secondary to chronic kidney disease (CKD), still represents a great challenge to nephrologists. Its management is tailored by the type of bone lesion - of high or low turnover - that cannot be accurately predicted by serum biomarkers of bone remodeling available in daily clinical practice, mainly parathyroid hormone (PTH) and alkaline phosphatase (AP). In view of this limitation, bone biopsy followed by bone quantitative histomorphometry, the gold-standard method for the diagnosis of ROD, is still considered of paramount importance. Read More

[Cavernoma complicated with biliopatia secondary to type 1 Gaucher disease: report of a Peruvian case].

Rev Gastroenterol Peru 2018 Jul-Sep;38(3):280-284

Facultad de Medicina Humana, Universidad Nacional San Luis Gonzaga. Ica, Perú; Sociedad Científica de Estudiantes de Medicina de Ica (SOCEMI). Ica, Perú.

Gaucher disease is an autosomal recessive lysosomal storage disorder characterized by deficiency of beta-glucosidase that would lead to the accumulation of glucosylceramide mainly in cells of the mononuclear phagocytic system causing systemic effectations. We present a patient of twenty years who is suffering from chronic pain in the left hypochondrium with episodes of bleeding for 3 years and sensation of thermal rise, physical examination revealed jaundice and massive splenomegaly, without neurological involvement. Severe osteoporosis, pancytopenia, and the presence of portal vein thrombosis with cavernomatous transformation complicated by portal biliopathy simulating a klatskin tumor, marrow and enzymatic studies were compatible with Gaucher disease, were shown as unexpected findings.

One year in review 2018: progress in osteoporosis treatment.

Clin Exp Rheumatol 2018 Nov-Dec;36(6):948-958. Epub 2018 Dec 6.

Rheumatology Unit, Department of Medicine, University of Pisa, Italy.

Osteoporosis is a generalised bone disease characterised by decreased bone mass and deterioration of bone microarchitecture predisposing to fragility fractures. Bone fractures are a remarkable social and economic health problem, and several studies have been carried out in order to reduce their occurrence. Inhibiting bone resorption and increasing bone formation are the mainstay of treatment, anti-catabolic and anabolic, respectively. Read More
