Accuracy of 2D CT-Based Measurements of Rotational Alignment of the Femoral Component for Total Knee Arthroplasty.

Yonsei Med J 2021 May;62(5):439-445

Department of Orthopedic Surgery, Severance Hospital, Yonsei University College of Medicine, Seoul, Korea.

Purpose: We aimed to investigate the accuracy of two-dimensional computed tomography (2D-CT)-based methods for measuring rotational alignment of the femoral component during total knee arthroplasty in comparison to reference values for three-dimensional (3D) reconstruction.

Materials And Methods: We selected the "most protruding transepicondylar axis section," "most protruding posterior condylar line section," and "distal femoral cut section" on 2D-CT images for 100 knees. We investigated posterior condylar angle (PCA) and condylar twist angle (CTA) values using three different methods on 2D-CT and compared to these values to those obtained using a 3D model. Read More

Telomere Replication: Solving Multiple End Replication Problems.

Front Cell Dev Biol 2021 1;9:668171. Epub 2021 Apr 1.

Department of Microbiology and Infectious Diseases, Faculty of Medicine and Health Sciences, Cancer Research Pavilion, Université de Sherbrooke, Sherbrooke, QC, Canada.

Eukaryotic genomes are highly complex and divided into linear chromosomes that require end protection from unwarranted fusions, recombination, and degradation in order to maintain genomic stability. This is accomplished through the conserved specialized nucleoprotein structure of telomeres. Due to the repetitive nature of telomeric DNA, and the unusual terminal structure, namely a protruding single stranded 3' DNA end, completing telomeric DNA replication in a timely and efficient manner is a challenge.

Postmortem evaluation of neuromuscular damages more extensive than the surgical intervention area after iliac crest bone graft.

Surg Radiol Anat 2021 Jun 5;43(6):827-831. Epub 2021 Jan 5.

Department of Anatomy, School of Medicine, Toho University, 5-21-16 Omori-Nishi, Ota-ku, Tokyo, 143-8540, Japan.

Several complications may occur following iliac bone grafting, one of the common sites for autologous bone harvesting. Of these, it is difficult to localize the damage in neurological complications due to the presence of several nerves in a similar distribution area with variations among individuals. To minimize these complications, conventional clinical anatomical studies using normal human cadavers have estimated the theoretical neurological damage area corresponding to the surgical intervention area.

Cardiac outcomes in patients with acute coronary syndrome attributable to calcified nodule.

Atherosclerosis 2021 02 11;318:70-75. Epub 2020 Nov 11.

Department of Cardiovascular Medicine, Tohoku University Graduate School of Medicine and Tohoku University Hospital, Sendai, Japan.

Background And Aims: Calcified nodule (CN) is an eruptive calcified mass causing acute coronary syndrome (ACS). Since coronary calcification is associated with an elevated cardiac event's risk, ACS attributable to CN may exhibit worse clinical outcome following percutaneous coronary intervention (PCI).

Methods: We retrospectively analyzed 657 ACS patients receiving PCI with newer-generation drug-eluting stent (DES) implantation under intravascular ultrasound (IVUS) guidance. Read More

Cureus 2020 Aug 29;12(8):e10121. Epub 2020 Aug 29.

Gastroenterology and Hepatology, Indiana University School of Medicine, Indianapolis, USA.

A 47-year-old female with metastatic cervical cancer and diverting colostomy presented with abdominal distention and minimal stool output from her colostomy. A computed tomography (CT) scan revealed a metastatic mass causing partial obstruction at the colostomy level and significant proximal colonic dilation. Her obstruction was relieved by the endoscopic placement of a metal stent through the stoma, with the stent's distal edge visible externally but not protruding beyond skin level. Read More

Balloon-based drug coating delivery to the artery wall is dictated by coating micro-morphology and angioplasty pressure gradients.

Biomaterials 2020 11 20;260:120337. Epub 2020 Aug 20.

IMES, MIT, 77 Massachusetts Avenue Cambridge, MA, USA; Cardiovascular Division, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA.

Paclitaxel coated balloon catheters (PCB) were developed as a polymer-free non-implantable alternative to drug eluting stents, delivering similar drug payloads in a matter of minutes. While PCB have shown efficacy in treating peripheral arterial disease in certain patient groups, restenosis rates remain high and there is no class effect. To help further optimize these devices, we developed a scanning electron microscopy (SEM) imaging technique and computational modeling approach that provide insights into the coating micromorphology dependence of in vivo drug transfer and retention.

Int J Angiol 2020 Sep 6;29(3):210-214. Epub 2019 Jun 6.

Department of Cardiovascular Surgery, St. Mary's Hospital, Kurume, Japan.

A male patient developed acute type B aortic dissection (AD) extending to the right external iliac artery (EIA) and left common femoral artery at the age of 56 years. Two months after the diagnosis of AD, he developed right renal infarction suggesting embolism, as the right renal artery arose from a false lumen containing a mural thrombus. Seven years later, at the age of 63 years, the patient was readmitted for acute onset of intermittent claudication in the right leg. Read More
