Background: Aiming at objective early detection of neuromotor disorders such as cerebral palsy, we propose an innovative non-intrusive approach using a pressure sensing device to classify infant general movements. Here we differentiate typical general movement patterns of the "fidgety period" (fidgety movements) vs. the "pre-fidgety period" (writhing movements).

Article Synopsis
  • - In June 2021 and January 2023, the FDA approved the antibodies aducanumab and lecanemab for Alzheimer's treatment, citing their ability to reduce amyloid-beta, but clinical benefits remain questionable.
  • - Clinical trial data show that the benefits of these treatments are minimal and similar to conventional medications, with some evidence suggesting that amyloid-PET results may indicate cell damage instead of just amyloid removal.
  • - The authors call for a revision of Alzheimer's diagnostic criteria, advocating for the use of cognitive decline and brain metabolism measures (FDG-PET) for diagnosis and efficacy assessments in future clinical trials.

Passive Alzheimer's immunotherapy: A promising or uncertain option?

Ageing Res Rev

September 2023

School of Clinical Medicine, UNSW Medicine & Health, St Vincent's Healthcare Clinical Campus Faculty of Medicine and Health, UNSW, Sydney, Australia; St Vincent's Hospital Centre for Applied Medical Research, St Vincent's Hospital Sydney, Darlinghurst, NSW, Australia.

Article Synopsis
  • The FDA has approved two anti-amyloid antibodies for Alzheimer’s treatment, leading to significant controversy over their clinical efficacy and safety.
  • While donanemab and lecanemab showed some clinical benefits, concerns about increased brain damage and uncertainty in amyloid removal signal have arisen from the trials.
  • The authors suggest that the FDA should pause current approvals and new antibody applications until further studies clarify these risks and benefits, recommending close monitoring of patients to better understand the impact of these treatments.

Article Synopsis
  • Passive immunotherapy for Alzheimer's disease has been in trial for over a decade but faced repeated failures until 2021 and January 2023, when the FDA approved aducanumab and lecanemab based on their effects on amyloid deposits and cognitive decline.
  • The approval of these antibodies relies on potentially questionable evidence regarding amyloid removal assessed through PET imaging, suggesting that observed results might reflect non-specific signals rather than true amyloid reduction.
  • The authors advocate for the use of repeat FDG PET and MRI in future immunotherapy trials to better assess the efficacy and safety of these treatments.

From Interaction to Intervention: How Mesenchymal Stem Cells Affect and Target Triple-Negative Breast Cancer.

Biomedicines

April 2023

Division of Cancer Research and Training, Department of Internal Medicine, Charles R. Drew University of Medicine and Science, David Geffen UCLA School of Medicine and UCLA Jonsson Comprehensive Cancer Center, Los Angeles, CA 90095, USA.

Triple-negative breast cancer (TNBC) lacks estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 expressions, making targeted therapies ineffective. Mesenchymal stem cells (MSCs) have emerged as a promising approach for TNBC treatment by modulating the tumor microenvironment (TME) and interacting with cancer cells. This review aims to comprehensively overview the role of MSCs in TNBC treatment, including their mechanisms of action and application strategies.

Aim: Because the tongue is a midline structure, studies on the neural correlates of lateralized tongue function are challenging and remain limited. Patients with tongue cancer who undergo unilateral partial glossectomy may be a unique cohort to study tongue-associated cortical activation, particularly regarding brain hemispheric lateralization. This longitudinal functional magnetic resonance imaging (fMRI) study investigated cortical activation changes for three tongue tasks before and after left-sided partial glossectomy in patients with squamous cell carcinoma of the tongue.

In behavioral research and clinical practice video data has rarely been shared or pooled across sites due to ethical concerns of confidentiality, although the need of shared large-scaled datasets remains increasing. This demand is even more imperative when data-heavy computer-based approaches are involved. To share data while abiding by privacy protection rules, a critical question arises whether efforts at data de-identification reduce data utility? We addressed this question by showcasing an established and video-based diagnostic tool for detecting neurological deficits.

Nutritional support in liver disease - an updated systematic review.

Curr Opin Gastroenterol

March 2023

Emeritus Professor of Clinical Medicine, Olive View-UCLA Medical Center, David Geffen-UCLA School of Medicine, Sylmar and Los Angeles, California, USA.

Purpose Of Review: The association of malnutrition and a poor prognosis does not prove that providing nutrition support improves that prognosis. The proof of such efficacy requires its demonstration in well designed and executed randomized trials. A systematic review of 40 such trials in 2014 failed to make such a finding.
