Etiology of avascular osteonecrosis of the femoral head

Morphologie, 2021
Avascular osteonecrosis of the femoral head (ONFH) is one of the causes of hip pain that clinicians need to know about. In many cases, it is a fortuitous discovery when pelvic X-rays is performed for another reason. In the other cases, pain reveals the disease. For the rheumatologist, a major part of the job is to look for a cause.

Denosumab Offers Relatively Lower Initial Protection Against Osteoporotic Vertebral Fractures in Treatment‐Naive Patients Compared With Zoledronate

Clinical Pharmacology &Therapeutics, EarlyView.
We compared the initial efficacy of denosumab (Dmab) and zoledronate (ZOL) in treatment‐naive patients with osteoporosis. This cohort study, based on TriNetX data, evaluated the risks of fractures and mortality using Kaplan–Meier survival analyses, with hazard ratios (HRs) and 95% confidence intervals (CIs).

Accu16S/AccuITS: Accurate and broadly applicable amplicon sequencing for absolute microbiome quantification

iMeta, EarlyView.
Traditional 16S rRNA gene and Internal Transcribed Spacer region amplicon sequencing provides only relative abundance, often leading to biased ecological interpretations. To overcome this limitation, we developed Accu16S/AccuITS, an absolute quantification method for bacterial and fungal amplicons based on synthetic internal spike‐in DNA with known ...

Estradiol replacement attenuates alendronate‐associated adverse effects on alveolar bone repair in ovariectomized rats

Journal of Periodontology, EarlyView.
Abstract Background Sodium alendronate (ALN) is widely used to treat postmenopausal osteoporosis, but both estrogen deficiency and antiresorptive therapy may impair alveolar bone repair after tooth extraction. A clinically relevant but insufficiently explored scenario involves estrogen‐deficient individuals receiving hormone replacement therapy (HRT ...

Hallux Valgus and Associated Foot Pathology in Ancient Egyptian Mummies: A Qualitative and Quantitative Computed Tomography Study

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The aim of this study was to gain information on the prevalence and manifestation of hallux valgus and associated foot pathology in ancient Egyptian mummies. Additionally, we investigated possible indicators of postmortem deformation of the feet during mummification. For this study, 34 mummies that had undergone whole body computed tomography (
