All possible two-subtest combinations of the core Wechsler Adult Intelligence Scale-IV (WAIS-IV) subtests were evaluated as possible viable short forms for estimating full-scale IQ (FSIQ). Validity of the dyads was evaluated relative to FSIQ in a large clinical sample (N = 482) referred for neuropsychological assessment. Sample validity measures included correlations, mean discrepancies, and levels of agreement between dyad estimates and FSIQ scores. In addition, reliability and validity coefficients were derived from WAIS-IV standardization data. The Coding + Information dyad had the strongest combination of reliability and validity data. However, several other dyads yielded comparable psychometric performance, albeit with some variability in their particular strengths. We also observed heterogeneity between validity coefficients from the clinical and standardization-based estimates for several dyads. Thus, readers are encouraged to also consider the individual psychometric attributes, their clinical or research goals, and client or sample characteristics when selecting among the dyadic short forms.

Objective: Physical activity (PA) has been linked to reduced Alzheimer's disease (AD) risk. However, less is known about its effects in the AD preclinical stage. We aimed to investigate whether greater PA was associated with lower plasma biomarkers of AD pathology, neural injury, reactive astrocytes, and better cognition in individuals with autosomal-dominant AD due to the presenilin-1 E280A mutation who are virtually guaranteed to develop dementia.

Objective: To investigate the clinical features, gene mutation profile, efficacy and prognostic factors of primary extranodal diffuse large B-cell lymphoma(EN-DLBCL).
Methods: A retrospective analysis was performed for 382 patients with primary EN-DLBCL with complete clinical data who were treated in West China Hospital from January 2013 to January 2023, and their clinical characteristics,gene mutation profile, efficacy and prognostic factors were analyzed.
Results: The median age of the 382 patients with EN-DLBCL was 56(18-89) years old.

: While it is generally assumed that common neurobehavioral assessments, such as the Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV), function similarly in clinical and non-clinical populations, this has not been validated in adults with congenital heart disease (CHD). In this study, we examined the latent factor structure of the WAIS-IV in adults with d-transposition of the great arteries (d-TGA) who participated in the Boston Circulatory Arrest Study. : The WAIS-IV was administered as part of a larger assessment battery.

Background: There is robust evidence that posttraumatic stress disorder (PTSD) is associated with neurocognitive deficits, such as executive dysfunction or memory dysfunction. Eye Movement Desensitization and Reprocessing (EMDR) is an evidence-based treatment for PTSD, in which eye movements (EMs) are performed during traumatic memory retrieval. We examined whether Eye Movement Desensitization (EMD) improves neurocognitive functioning in PTSD patients, in comparison with a retrieval-only control condition without EMs.

Objective: to study the features of cognitive disorders in the remote period following exposure to ionizing radiation (IR) in the elderly participants of the liquidation of the consequences of the Chornobyl NPP accident (Chornobyl clean-up workers) with chronic cerebrovascular disorders.
Materials And Methods: The retrospective and prospective cohort study with the external and internal controlgroups. The randomized sample of the male elderly participants (attained age more than 60 years old) in liquidationof the consequences of the accident (Chornobyl clean-up workers, liquidators) at the Chornobyl nuclear power plant(ChNPP) in 1986-1987 (main group, n = 52) recruited from the Clinico-epidemiological registry (CER) of StateInstitution «National Research Center for Radiation Medicine, Hematology and Oncology of The National Academyof Medical Sciences of Ukraine» (NRCRMHO) with verified chronic cerebrovascular disorders (CVD) was examined.
