Article Synopsis
  • The Trifecta valve was withdrawn from the market due to concerns about early structural valve deterioration, particularly aortic regurgitation, which occurred in patients within five years of implantation.
  • A study involving 171 patients undergoing redo aortic valve replacement found that those with Trifecta valves experienced earlier onset and more severe aortic regurgitation compared to those with other valve types.
  • The research indicated that mortality rates were significantly higher in patients with Trifecta valves, suggesting that their use could affect outcomes in studies comparing surgical and transcatheter valve replacements.

Cardiotoxicity from chemotherapy regimens has been long reported. However, the understanding of cardiac side effects of biological therapies is rapidly evolving. With cancer patients achieving higher life expectancy due to the use of personalized medicine and novel targeted anticancer agents, the occurrence of cardiotoxicity is becoming more significant.

Asian American and Pacific Islanders (AAPI) are the fastest growing racial minority in the United States. With more than 40 subgroups in the diaspora, 1 in 10 American youths will be of Asian origin by 2060. Racism-defined as prejudice, discrimination or antagonism on the basis of membership in a particular racial or ethnic group-is increasingly recognized as a public health crisis.

Purpose: To compare visual acuity (VA) and OCT outcomes in patients with idiopathic macular telangiectasia (IMT) type 2 who underwent pars plana vitrectomy (PPV) surgery for full-thickness macular holes (FTMHs) versus those who elected to be medically managed (MM) without surgery.

Design: Comparative retrospective case series.

Participants: Patients with IMT type 2 and FTMH.

A microwave imaging-based technique for 3D localization of an in-body RF source is presented. Such a technique can be useful for localization of an RF source as in wireless capsule endoscopes for positioning of any abnormality in the gastrointestinal tract. Microwave imaging is used to determine the dielectric properties (relative permittivity and conductivity) of the tissues that are required for a precise localization.

Asian Indians represent a significant portion of the largest growing race of Asians in the past decade in the United States. This selective review examines major cultural themes related to first- and second-generation Asian Indians living in the United States as they impact psychological and psychiatric dysfunction in this population. Specifically, we review the impact of Asian Indian culture on mental health, discuss the impact of acculturation and ethnic identity development on the mental health of Indian-Americans, and focus on typical mental health problems of Asian Indian adolescents, women and elderly in America.

Widely used medical imaging systems in clinics currently rely on X-rays, magnetic resonance imaging, ultrasound, computed tomography, and positron emission tomography. The aforementioned technologies provide clinical data with a variety of resolution, implementation cost, and use complexity, where some of them rely on ionizing radiation. Microwave sensing and imaging (MSI) is an alternative method based on nonionizing electromagnetic (EM) signals operating over the frequency range covering hundreds of megahertz to tens of gigahertz.

In some biomedical applications such as wireless capsule endoscopy, the localization of an in-body radio-frequency (RF) source is important for the positioning of any abnormality inside the gastrointestinal tract. With knowledge of the location, therapeutic operations can be performed precisely at the position of the abnormality. Electrical properties (relative permittivity and conductivity) of the tissues and their distribution are utilized to estimate the position.

Objective: The NBME Psychiatry Subject Examination (PSE) is used throughout North America to test MS-III end-of-clerkship knowledge; yet, literature on PSE preparatory methods remains sparse. This study assesses the effect of a curriculum intervention on NBME PSE scores.

Method: An optional 1.
