AI Article Synopsis

  • The addition of co-stimulatory domains to CAR T cells boosts their persistence and reactivity, but it also raises the risk of toxicities due to heightened cytokine release.
  • This study presents the first evidence of anti-CD19 CAR-T cell therapy using a single activation domain, highlighting its favorable safety profile.
  • Two patients with heavily treated B cell malignancies demonstrated durable responses lasting up to 28 months.

Article Abstract

The persistence and reactivity of CAR T cells were enhanced by adding co-stimulatory domains, which is the basis of currently approved CAR-T cell therapies. However, this comes at the expense of increasing toxicities from the strong cytokine release effect. This is the first report from anti-CD19 CAR-T cell therapy with a single activation domain to show a favourable safety profile and clinical efficacy with two patients who achieved durable responses up to 28 months in a cohort with heavily pretreated B cell malignancies.

The current unavailability of efficient myocardial repair therapies constitutes a significant bottleneck in the clinical management of myocardial infarction (MI). Ginsenoside Rb1 (GRb1) has emerged as a compound with potential benefits in safeguarding myocardial cells and facilitating the regeneration of myocardial tissue. However, its efficacy in treating MI-related ischemic conditions is hampered by its low bioavailability and inadequate angiogenic properties.

Background: Timely recognition of acute ischemic stroke (AIS) is essential to identify patients who may be eligible for acute intervention. Protocols to streamline systems-based care, such as "stroke alerts" in the emergency department (ED) can safely reduce time-to-care while enhancing safety. However, clinician adherence to stroke alert criteria is poorly described.

Chronic cough management: Practical guidelines and PICO-based evidence for treatment.

Asian Pac J Allergy Immunol

December 2024

Department of Clinical Epidemiology and Biostatistics, Faculty of Medicine Ramathibodi Hospital, Mahidol University, T hailand.

This part reviews the management of chronic cough and proposes a management algorithm. Despite proven improvements in quality of life following chronic cough treatment, a clear understanding of the disease and the evidence for the efficacy of some treatments remain vague. Eight key questions regarding the treatment in the uncertain areas were systematically addressed based on the PICO framework and applying the GRADE system for evidence synthesis to provide the strength of recommendation and quality of evidence for key questions, with narrative components for the description of other chronic cough treatment including non-pharmacological therapy.

Mutations that overexpress the epidermal growth factor receptor (EGFR) are linked to cancers like breast (15-20%), head and neck (10-15%), colorectal (5-8%), and non-small cell lung cancer (10-50%), especially in East Asian populations. EGFR activation stimulates "RAS/RAF/MEK/ERK, PI3K/Akt, and MAPK" pathways, which enhance cell division, survival, angiogenesis, and tumor growth while inhibiting apoptosis and metastasis. Secondary mutations (e.

The objective of this study was to examine the efficacy of the concurrent utilization of estradiol valerate and kuntai capsule (a Chinese herbal preparation) in addressing premature ovarian failure (POF) and its ramifications for ovarian hemodynamics and sex hormone levels. A retrospective study of 104 patients with POF was conducted, dividing them into control (n=50) and observation groups (n=54). The control group received estradiol valerate, while the observation group received estradiol valerate and KunTai capsules over 12 weeks.
