Biomarkers.

Background: Biomarkers for Alzheimer's disease (AD) in blood samples has the potential to facilitate early diagnosis and improve the accuracy of AD diagnosis. Plasma phosphorylated tau (p-tau) is a key biomarker for AD; however, its utility for estimating the prevalence of AD and screening for cognitive impairment is still limited.

Method: The study recruited 71 participants over the age of 40.

Biomarkers.

Background: The validation of blood-based biomarkers presents a promising role in Alzheimer's disease (AD) diagnosis owing to their accessibility and diminished invasiveness. However, despite awareness of confounding factors like kidney function, inaccuracies persist in AD diagnosis using plasma p-tau. Notably, diverse conditions that modify blood-brain barrier (BBB) permeability have been linked to high plasma p-tau levels, irrespective of AD pathophysiology.

Biomarkers.

Background: Alzheimer's disease (AD) is referred as one of the most common causes of dementia and frailty. To address this impending public health crisis, there is a critical need to identify simple and reliable biomarkers for early AD diagnosis. Recent research has highlighted the potential utility of salivary lactoferrin (Lf) as a promising biomarker for AD diagnosis.

In this study, we aimed to assess the performance of plasma GFAP compared to other biomarkers.

Biomarkers.

Background: The blood-brain barrier (BBB) is considered the crucial part of neuroprotection from various neurological insults including infection, inflammation, and neurodegeneration including Alzheimer's disease (AD). The cerebral small vessel disease (CSVD) pathologies especially cerebral microbleeds (CMBs) and gadolinium enhancement might reflect the disruption of BBB. The correlation between BBB permeability measured by cerebrospinal fluid (CSF)/plasma albumin quotient (Qalb) and CSVD biomarkers is poorly understood.

Biomarkers.

Background: Tau-PET and plasma phosphorylated tau (p-tau) have emerged as pivotal biomarkers for Alzheimer's disease. Despite the practical advantages of using plasma p-tau, there is limited understanding regarding its relationship with the topographic distribution of tau-PET, particularly within the Southeast Asian population. This study aims to elucidate the correlation between plasma p-tau levels and the spatial patterns observed in tau-PET among Thai patients diagnosed with amnestic mild cognitive impairment (MCI) or mild dementia due to probable Alzheimer's disease (AD).

Biomarkers.

Background: Plasma tau phosphorylated at Thr217 (p-tau217) has demonstrated excellent performance in identifying individuals with Alzheimer's disease (AD) in both research and memory clinic settings. Nonetheless, implementing plasma p-tau217 into clinical practice remains a challenge requiring careful clinical judgement and conservative interpretation near the cutpoint. The present study proposes a strategy that utilizes Bayes theorem in considering the clinical context, individualized (ie.

Acute kidney injury following CAR-T cell therapy: a nephrologist's perspective.

Chimeric antigen receptor T (CAR-T) cell therapy, an emerging personalized immunotherapy for various haematologic malignancies, autoimmune diseases and other conditions, involves the modification of patients' T cells to express a chimeric antigen receptor that recognizes tumour or autoimmune cell antigens, allowing CAR-T cells to destroy cancerous and other target cells selectively. Despite remarkable clinical improvements in patients, multiple adverse effects have been associated with CAR-T cell therapy. Among the most recognized adverse effects are cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome and tumour lysis syndrome.

Anti-Mesothelin CAR-NK cells as a novel targeted therapy against cervical cancer.

Statistical methods to adjust for the effects on intervention compliance in randomized clinical trials where precision treatment rules are being developed.

Background: Heterogeneity of treatment effects (HTEs) can occur because of either differential treatment compliance or differential treatment effectiveness. This distinction is important, as it has action implications, but it is unclear how to distinguish these two possibilities statistically in precision treatment analysis given that compliance is not observed until after randomization. We review available statistical methods and illustrate a recommended method in secondary analysis in a trial focused on HTE.
