The Impact of COVID-19 on the Optimal Management of Osteoporosis.

J Bone Metab 2021 May 31;28(2):115-122. Epub 2021 May 31.

Department of Orthopedic Surgery, Ewha Womans University, College of Medicine, Mokdong Hospital, Seoul, Korea.

Osteoporosis does not take a break while Coronavirus disease 2019 (COVID-19) stunned and overtook everyone's lives. Medical resources were immediately shifted, self-isolation and telemedicine were expanded, ambulatory care services such as bone densitometry and osteoporosis-centered clinics came to a near halt. Progress with fracture prevention has been challenged because osteoporotic fracture with low energy injury is more prevalent even though restriction of people's movement. Read More

Effects of Ultrashort Wave Therapy on Inflammation and Macrophage Polarization after Acute Lung Injury in Rats.

Bioelectromagnetics 2021 Jun 15. Epub 2021 Jun 15.

Rehabilitation Medicine Center, The First Affiliated Hospital of University of South China, Hengyang, People's Republic of China.

Acute lung injury (ALI) features dysregulated pulmonary inflammation. Ultrashort waves (USWs) exert anti-inflammatory effects but no studies have evaluated their activity in ALI. Herein, we used an in vivo lipopolysaccharide (LPS)-induced ALI model to investigate whether the anti-inflammatory activity of USWs is mediated by altering the polarization of M1 to M2 macrophages.

ROTEM Testing for Direct Oral Anticoagulants.

Semin Thromb Hemost 2021 Jun 15. Epub 2021 Jun 15.

Department of Internal Medicine I, Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, Martin, Slovak Republic.

Direct oral anticoagulants (DOACs) are increasingly used worldwide for the prevention of stroke in patients with atrial fibrillation and to prevent or treat venous thromboembolism. In situations such as serious bleeding, the need for urgent surgery/intervention or the management of a thromboembolic event, the laboratory measurement of DOACs levels or anticoagulant activity may be required. Rotational thromboelastometry (ROTEM) is a viscoelastic hemostatic assay (VHA) which has been used in emergencies (trauma and obstetrics), and surgical procedures (cardiac surgery and liver transplants), but experience with this assay in DOACs-treated patients is still limited.

Detection of fixation points using a small visual landmark for brain-computer interfaces.

J Neural Eng 2021 Jun 15. Epub 2021 Jun 15.

Dept. of Biomedical Engineering, Tianjin University, School of Precision Instrument and Opto-Electronics Engineering, Tianjin 300072, Tianjin, 300072, CHINA.

Abstract- Objective: The speed of visual brain-computer interfaces (v-BCIs) has been greatly improved in recent years. However, the traditional v-BCI paradigms require users to directly gaze at the intensive flickering items, which would cause severe problems such as visual fatigue and excessive visual resource consumption in practical applications. Therefore, it is imperative to develop a user-friendly v-BCI. Read More
