Rationale And Objectives: This study aimed to evaluate the effectiveness of two techniques "autologous blood patch (ABP) and saline sealing" in preventing pneumothorax during CT-guided percutaneous transthoracic lung biopsies (PTTLB).
Materials And Methods: We analyzed 218 PTTLB procedures performed on 202 patients, categorizing them into three groups: those receiving ABP, those receiving saline, and a control group with no intervention. We assessed pneumothorax and catheter drainage rates and analyzed potential risk factors, including demographics, procedural positioning, pleura-skin distance, lesion characteristics, and emphysema scores.
Background: Carotid artery stenting (CAS) is an interventional management in preventing ischemic stroke caused by carotid artery stenosis. After the treatment with CAS, in-stent restenosis caused by neointimal hyperplasia may develop.
Purpose: This study aims to obtain a better determination of neointimal hyperplasia using superb microvascular imaging (SMI), which provides a high-quality visualization of the endoluminal lesions, and to compare these results with B-mode and Doppler ultrasound (US).
The optimal design of a proportional-integral-derivative controller with two cascaded first-order low-pass filters (PID-FF) for non-ideal buck converters faces significant challenges, including effective disturbance rejection, robustness to parameter variations, and the mitigation of high-frequency signal noise, with existing approaches often struggling and leading to suboptimal performance in practical applications. This study addresses these challenges by introducing a constraint on the open-loop crossover frequency to mitigate high-frequency noise and ensuring the controller prioritizes maintaining constant output voltage and robust responsiveness to input voltage and load current variations. This study also introduces an innovative metaheuristic algorithm, the opposition-based snake optimizer with pattern search (OSOPS), designed to address these limitations.

Methods: The study was conducted in a tertiary Training and Research Hospital between 1 December 2018 and 1 May 2019 in 225 postmenopausal women who applied to the Family Medicine outpatient clinic and bone mineral density (BMD) outpatient clinics for BMD measurement or had previously had this measurement at least once.
