Bone composition and vitamin D after Pólya gastrectomy

With the aim of evaluating bone phosphorus/hydroxyproline ratio (P/Hypro) as an index of osteomalacia, this bone index and the bone mineral content (BMC) have been investigated together with other indices of calcium metabolism in 27 gastrectomized patients. None of the patients had clinically manifest bone symptoms. The mean values of bone P/Hypro, BMC, plasma calcium and plasma magnesium were subnormal; the mean values of serum parathyroid hormone (iPTH) and plasma alkaline phosphatase were elevated. Mean serum 25-hydroxycholecalciferol (25-OH-D) did not differ from normal. A significant positive correlation was found between bone P/Hypro and serum 25-OH-D, but no significant correlation between bone P/Hypro and BMC. Serum 25-OH-D and bone P/Hypro were significantly lower and serum iPTH was significantly higher in a subgroup of 12 patients with no regular supplementary intake of vitamin D. In conclusion, the gastrectomized patients had blood biochemical evidence of a mild vitamin D insufficiency and the low bone P/Hypro values can be explained by mild osteomalacic changes in bone.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
