The α-synuclein seed amplification assay: Interpreting a test of Parkinson's pathology.

Parkinsonism Relat Disord

December 2024

Department of Translational Neuroscience and the Muhammad Ali Parkinson Center, Barrow Neurological Institute, Phoenix, AZ, USA.

The α-synuclein seed amplification assay (αSyn-SAA) sensitively detects Lewy pathology, the amyloid state of α-synuclein, in the cerebrospinal fluid (CSF) of patients with Parkinson's disease (PD). The αSyn-SAA harnesses the physics of seeding, whereby a superconcentrated solution of recombinant α-synuclein lowers the thermodynamic threshold (nucleation barrier) for aggregated α-synuclein to act as a nucleation catalyst ("seed") to trigger the precipitation (nucleation) of monomeric α-synuclein into pathology. This laboratory setup increases the signal for identifying a catalyst if one is present in the tissue examined.

New Technique of Commissural Reconstruction: "Ship Technique" in Rheumatic Mitral Repairs.

Ann Thorac Surg Short Rep

September 2024

Department of Medicine, BronxCare Health System, Bronx, New York.

The commissures are the supporting unit for the leaflets, and they play a vital role in the diastolic and systolic functioning of the mitral valve. This report describes the "ship technique" of commissural reconstruction in rheumatic mitral stenosis repairs. The technique overcomes gradients that are often encountered with limited commissurotomy and residual leaks observed with extended commissurotomy.

Cardiovascular Disease and Cancer: A Dangerous Liaison.

Arterioscler Thromb Vasc Biol

January 2025

Cardiovascular Research Center, New York University Langone Health, New York University Grossman School of Medicine. (A.A.C.N., J.M.D., K.J.M.).

The field of cardio-oncology has traditionally focused on the impact of cancer and its therapies on cardiovascular health. Mounting clinical and preclinical evidence, however, indicates that the reverse may also be true: cardiovascular disease can itself influence tumor growth and metastasis. Numerous epidemiological studies have reported that individuals with prevalent cardiovascular disease have an increased incidence of cancer.

Medical large language models are vulnerable to data-poisoning attacks.

Nat Med

January 2025

Department of Neurosurgery, NYU Langone Health, New York, NY, USA.

The adoption of large language models (LLMs) in healthcare demands a careful analysis of their potential to spread false medical knowledge. Because LLMs ingest massive volumes of data from the open Internet during training, they are potentially exposed to unverified medical knowledge that may include deliberately planted misinformation. Here, we perform a threat assessment that simulates a data-poisoning attack against The Pile, a popular dataset used for LLM development.

The imposter phenomenon (IP) is a destructive set of beliefs, traits, and experiences in which high-achieving individuals fail to internalize their accomplishments and falsely perceive themselves as frauds. IP is a function of underrepresentation and contributes to and perpetuates a cycle of low self-worth, perfectionism, and anxiety, all of which negatively affect job performance and reinforce the IP cycle. Mitigating the deleterious effects of IP requires first naming this phenomenon and recognizing the patterns of IP.

Gaps in Physical Medicine and Rehabilitation for Blindness and Low Vision: The Imperative of Rehabilitation for Visual Disability.

Am J Phys Med Rehabil

February 2025

From the Department of Rehabilitation Medicine, RUSK Rehabilitation at NYU Langone Health, New York, New York (AG, MB, GH-F, AS, J-RR); Department of Biomedical Engineering, NYU Tandon School of Engineering, New York, New York (YHH, SR, J-RR); Rehabilitation Institute, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania (HS); Department of Physical Medicine and Rehabilitation, Cedars-Sinai, Los Angeles, California (PR); and Department of Physical Therapy, New York University, New York, New York (SR).

Persons with blindness and low vision experience increased fall and injury risk beyond atypical biomechanics and balance impairments. Falling risk doubles with blindness, and more than triples with depth perception losses. Despite this, physical therapy focuses on musculoskeletal injuries postevent rather than taking a proactive and preventative approach for persons with blindness and low vision.

A Perspective on the MARS2 Trial.

J Thorac Oncol

January 2025

Department of Cardiothoracic Surgery, New York University Langone Health, New York, New York. Electronic address:

Introduction: The phase 3 randomized controlled trial of extended pleurectomy decortication and chemotherapy versus chemotherapy alone for pleural mesothelioma (PM) (MARS2) reported "extended pleurectomy decortication was associated with worse survival to 2 years, and more serious adverse events for individuals with resectable PM, compared with chemotherapy alone." These results have led to considerable discourse regarding the future role of surgery for PM, and there has not been unanimity in the mesothelioma surgical community regarding the trial interpretation. This "perspective" evaluates MARS2 using internationally renowned PM experts who either agreed with the trial interpretation or who found issues with its conduct which may have influenced the results.
