Advanced ankylosing spondylitis: a multisite, multimodality densitometric analysis for investigation of bone loss in the axial and appendicular skeleton.
The aim of this study was to investigate if there is a bias in bone mineral density measurements among major densitometric techniques across multiple skeletal sites. ⋯ Low bone mineral density is prevalent in advanced ankylosing spondylitis patients, predominating in the spine. Bone mineral density measurements have systematic differences when compared to each other. Knowledge of these offsets is useful for improved diagnosis of regional bone loss that allows for targeted treatment of osteoporosis. Three-dimensional quantitative computed tomography is more suitable for evaluating spinal osteoporosis in advanced ankylosing spondylitis than dual-energy X-ray absorptiometry, which rather underestimates bone loss.

An evaluation of people's knowledge of adult vaccination information level and attitudes during the pandemic Era.
This research was carried out to evaluate people's knowledge of adult vaccination and their attitude and to observe the effect of the pandemic era on this situation. ⋯ As a result, it seems that we are far from the goals set by the health authorities for adult vaccination. We observed that the COVID-19 pandemic raised awareness toward pneumococcus and influenza vaccines and interest toward adult vaccinations and at the same time changed the thoughts against adult vaccinations.

Nonalcoholic fatty liver disease: scintigraphy in the diagnosis of steatohepatitis.
Nonalcoholic fatty liver disease is the most prevalent cause of chronic liver disease worldwide. Nonalcoholic steatohepatitis is associated with increased mortality rates due to the liver and cardiovascular diseases. The gold standard for discriminating nonalcoholic fatty liver disease activity and staging is the anatomopathological examination, which is an invasive method. In this regard, noninvasive methods, such as scintigraphy, have been under investigation. This study investigated the role of scintigraphy in the diagnosis of nonalcoholic steatohepatitis in obese patients with nonalcoholic fatty liver disease undergoing bariatric surgery. ⋯ Scintigraphy was not proven to be a useful method to differentiate patients with and without nonalcoholic steatohepatitis.

Shear-wave elastography evaluation of adrenal glands in healthy newborns: a preliminary study.
Establishing standard shear-wave elastography (SWE) values for healthy newborns can help distinguish normal conditions of the adrenal gland (AG) from pathological conditions. We aimed to establish a reference data set for AG stiffness values using SWE in healthy newborns. ⋯ This study is the first SWE study to evaluate the AG in healthy newborns. Our study's data can be used as a reference for future research.

Effect of Tirofiban on new cerebral microbleeds after mechanical thrombectomy in patients with acute ischemic stroke.
The aim of this study was to analyze the effect of tirofiban on new cerebral microhemorrhage after mechanical thrombectomy in patients with acute ischemic stroke. ⋯ The application of tirofiban in mechanical thrombectomy of patients with acute ischemic stroke has high safety, effectively reduces the occurrence of new cerebral microhemorrhage, and provides a guarantee for patient safety.
