Background: Hyperemesis gravidarum (HG), related to protracted vomiting and nausea, is a common cause of hospitalization during the first trimester of pregnancy. It can be accompanied by ketonuria, dehydration, and weight loss. Our aim was to investigate bone loss in patients with HG.
Methods: In our study, we investigated decreased bone mineral density (BMD)in a total of 79 patients (40 HG and 39 control) by means of dual energy X-ray absorptiometry (DEXA) measurements and laboratory parameters related to HG. All patients received DEXA measurement during the early postpartum period (usually two days after delivery, prior to discharge).This study was registered in the database via the Protocol Registration and Results System (PRS) (NCT03127293).
Results: There was no significant difference in DEXA results (lumbar spine and total hip) and laboratory parameters between case and control groups, although a significant difference in vitamin intake was identified between cases and controls (65% vs. 92%, respectively, p = 0.003). Except for low serum levels of vitamin D, other laboratory parameters were in normal range in both groups.
Conclusion: Pregnancies complicated by HG did not have decreased bone mineral density compared to those without HG. There is no evidence to relate HG to future osteoporosis.

Background: L-arginine (Arg) is a semi-essential amino acid that can be used as a key mediator for the release of growth hormone (GH), insulin-like growth factor-1(IGF-1), and other growth factors. In this study, we comprehensively evaluated the effect of Arg intake on bone growth and associated markers.
Methods: The study involved 24 Sprague-Dawley rats (12 males, 12 females) divided into two groups (Age = 24 days).
Posteruptive Loss of Proteins in Porcine Enamel.

Tooth enamel maturation requires the removal of proteins from the mineralizing enamel matrix to allow for crystallite growth until full hardness is reached to meet the mechanical needs of mastication. While this process takes up to several years in humans before the tooth erupts, it is greatly accelerated in the faster-developing pigs. Pig teeth erupt with softer, protein-rich enamel that is similar to hypomineralized human enamel but continues to harden quickly after eruption.

Background: The objective of this study is to investigate the potential association between change in body composition before and after cetuximab-based therapy and the prognostic outcomes among individuals diagnosed with advanced colorectal cancer.
Methods: A retrospective analysis was undertaken on a cohort of 81 patients diagnosed with RAS wild-type (WT) metastatic colorectal cancer (mCRC) who were treated with cetuximab-based first-line therapy. To assess relevant body composition parameters, quantitative computed tomography (QCT) scans were conducted both before and after cetuximab treatment.
Impact of dementia and mild cognitive impairment on bone health in older people.

MRC Lifecourse Epidemiology Centre, University of Southampton, Southampton, UK.
Mild cognitive impairment, dementia and osteoporosis are common diseases of ageing and, with the increasingly ageing global population, are increasing in prevalence. These conditions are closely associated, with shared risk factors, common underlying biological mechanisms and potential direct causal pathways. In this review, the epidemiological and mechanistic links between mild cognitive impairment, dementia and skeletal health are explored.
