Background: Subjective Cognitive Decline (SCD) is recognized as a risk stage for future cognitive impairment and dementia. The criteria for SCD include normal performance on neuropsychological testing; however, there is a lack of consensus regarding standard score cut-offs for neuropsychological tests to define cognitive impairment and to differentiate between SCD and Mild Cognitive Impairment (MCI). This study aimed to assess the frequency of SCD diagnosis using various neuropsychological definitions of cognitive normality and to characterize the sociodemographic and neuropsychological features of SCD patients diagnosed under these criteria.

Article Synopsis
  • The study investigates whether patients with amnestic cognitive impairment (aMCI) can accurately self-assess their memory performance during a neuropsychological evaluation, comparing their abilities to those of healthy individuals.
  • Participants included 40 aMCI patients and 40 healthy controls, who completed the Subjective Memory Complaints (SMC) scale before and after the assessment; results showed that aMCI patients reported higher ongoing memory complaints than healthy controls.
  • After the assessment, healthy controls’ memory complaints decreased, while aMCI patients’ complaints remained high, suggesting that aMCI patients struggle to adjust their self-reported memory issues based on their assessment performance.

Chimeric antigen receptor (CAR) T-cell therapy fails to achieve durable responses in over 60% of relapsed/refractory (R/R) large B-cell lymphoma (LBCL) patients in the third or later line setting. After CAR-T failure, survival outcomes are heterogeneous and a prognostic model in this patient population is lacking. A training cohort of 216 patients with progressive disease (PD) after CAR-T from 12 Spanish centers was used to develop the Post-CAR Prognostic Index (PC-PI); primary endpoint was overall survival (OS) from CAR-T progression.

Herein, we report the creation of a novel sensitive electrochemical sensing platform based on a copper and exfoliated graphene oxide (Cu-eGO) nanocomposite using a facile synthesis technique, which simultaneously removes the sodium ions that result from the exfoliation process to generate eGO from graphite. This novel Cu-eGO nanocomposite was characterized via SEM, EDX, Raman and XPS. The Cu-eGO/GCE exhibited much greater activity for the electrochemical oxidation of methimazole than the eGO/GCE or bare GCE.

Background: The concept of amnestic mild cognitive impairment (aMCI) was developed to identify patients at an initial stage of Alzheimer's disease (AD). However, some patients with aMCI do not present biomarkers of amyloid pathology or neuronal injury.

Objective: To know the natural history of amyloid-negative and neurodegeneration-negative patients with aMCI, namely to ascertain: 1) whether these patients remain cognitively stable or they present a slow decline in neuropsychological tests; 2) whether the memory complaints subside with the apparently benign clinical course of the disorder or if they persist along the time.

Chimeric antigen receptor (CAR)-T cell therapy is approved for the treatment of relapsed/refractory (R/R) large B cell lymphoma (LBCL). However, elderly patients might not be candidates for this therapy due to its toxicity, and criteria for candidate selection are lacking. Our aim was to analyze efficacy and toxicity results of CAR-T cell therapy in the population of patients 70 years and older as compared to those obtained in younger patients in the real-world setting.

Article Synopsis
  • This study analyzed the impact of community-acquired respiratory viruses (CARVs) on lower respiratory tract diseases in 235 adult recipients of allogeneic stem cell transplants (allo-SCT).
  • It found no significant differences in 100-day overall survival rates among different CARVs, which ranged from 78% to 90%.
  • Key risk factors for all-cause mortality included corticosteroid use and low absolute lymphocyte counts, suggesting that the level of immunosuppression is more critical than the virulence of the viruses themselves.
