Computed tomography fluoroscopy-guided percutaneous biopsy of pulmonary nodules ≤ 10 mm: retrospective analysis of procedures performed during the COVID-19 pandemic.

Objective: To evaluate the diagnostic performance of computed tomography (CT) fluoroscopy-guided percutaneous transthoracic needle biopsy (PTNB) in pulmonary nodules ≤ 10 mm during the coronavirus disease 2019 pandemic.

Materials And Methods: Between January 1, 2020 and April 30, 2022, a total of 359 CT fluoroscopy-guided PTNBs were performed at an interventional radiology center. Lung lesions measured between 2 mm and 108 mm.

The effect of platelet-rich plasma on the repair of muscle injuries in rats.

Objective: The need for therapeutic options for muscle injuries, which are increasingly frequent among sports practitioners, was the motivation for this experimental study, which had the aim of evaluating the histological effects of platelet-rich plasma (PRP) on repairs to muscle tissues of rats.

Methods: PRP was obtained by means of double centrifugation of blood from five animals. In 30 rats, an injury was produced in the middle third of the belly of the gastrocnemius muscle of each hind limb.

[Insufficient loss of weight and/or absence of DM2 remission after Roux-en-Y gastric bypass: factors that may influence the unsatisfactory results].

Background: Roux-en-Y gastric by-pass is considered one of the most effective treatments for maintaining long-term weight loss. However, it is associated to failures manifested by the inability to maintain weight loss, weight gain or poor glycemic control.

Objective: Study the possible factors that influence weight loss failure and/or DM2 remission.
