Total knee arthroplasty improves energy conversion efficiency during walking in patients with knee osteoarthritis.

Background: Energy conversion efficiency of human gait can be evaluated by calculating the ratio of conversion of mechanical energy from vertical motion to horizontal motion of the center of gravity through the movement of the joints. Osteoarthritis (OA) of the knee joint impairs this energy conversion efficiency. Total knee arthroplasty is the standard treatment for knee OA.

Predictive Factors of Unexpected Hospitalization within Six Months of Undergoing Percutaneous Coronary Intervention in Patients with Chronic Coronary Disease.

Background Recent guidelines recommend dual antiplatelet therapy (DAPT) for six months following percutaneous coronary intervention (PCI) in patients with chronic coronary disease, as unexpected hospitalization can trigger DAPT discontinuation. This study evaluated the predictive factors for unexpected hospitalization within six months after PCI in patients with chronic coronary disease. Methods This prospective multicenter study included 412 patients who underwent PCI for chronic coronary disease.

Long-Term Kawasaki Disease Complication: Thrombotic Coronary Aneurysm Leading to Acute Myocardial Infarction.

Acute myocardial infarction caused by coronary artery aneurysms typically occurs within 1 to 2 years after Kawasaki disease onset. We report a rare case of sudden death from acute myocardial infarction caused by thrombotic occlusion in a coronary artery aneurysm in a 41-year-old patient diagnosed Kawasaki disease at age 5 years.

Single-walled Carbon Nanotubes Wrapped with Charged Polysaccharides Enhance Extracellular Electron Transfer.

Microbial electrochemical systems (MESs) rely on the microbes' ability to transfer charges from their anaerobic respiratory processes to electrodes through extracellular electron transfer (EET). To increase the generally low output signal in devices, advanced bioelectrical interfaces tend to augment this problem by attaching conducting nanoparticles, such as positively charged multiwalled carbon nanotubes (CNTs), to the base carbon electrode to electrostatically attract the negatively charged bacterial cell membrane. On the other hand, some reports point to the importance of the magnitude of the surface charge of functionalized single-walled CNTs (SWCNTs) as well as the size of functional groups for interaction with the cell membrane, rather than their polarity.

Robotic surgery is associated with a decreased risk of circumferential resection margin positivity compared with conventional laparoscopic surgery in patients with rectal cancer undergoing mesorectal excision: A systematic review and meta-analysis.

Objective: To investigate whether robotic surgery (RS) decreases the risk of circumferential resection margin (CRM) positivity compared with conventional laparoscopic surgery (LS) in patients with rectal cancer (RC) undergoing mesorectal excision (ME).

Background: Although it is well known that CRM positivity affects postoperative outcomes in patients with RC undergoing ME, few studies have investigated whether RS is superior to conventional LS for the risk of CRM positivity.

Methods: We performed a comprehensive electronic search of the literature up to December 2022 to identify studies that compared the risk of CRM positivity between patients with RC undergoing robotic and conventional laparoscopic surgery.
