Biomarkers.

Background: Alzheimer's disease (AD) has been mainly thought of as a disease involving gray matter changes. However, despite known correlations between white matter integrity and cognition, less is known about how disruptions to white matter during the development of AD underpin cognitive impairment. This study tests the associations between disruptions to white matter along the AD clinical continuum (cognitive unimpaired (CU): cognitive impaired (CI) - Mild Cognitive Impairment (MCI) and AD) and cognition using diffusion tensor imaging (DTI) and multi-tissue neurite and orientation dispersion and density imaging (mtNODDI) models of the multi-shell connectome diffusion MRI (ms-dMRI) data from the Alzheimer's Disease Connectome Project (ADCP).

Biomarkers.

Background: Accelerated aging is strongly linked to adverse social exposome and accelerated aging of the brain may be a dementia risk factor. Machine-learning can estimate the biological "brain age" from neuroimages, which provides complementary information to the chronological/calendar age. The difference between biological and chronological age is referred to as the "brain age gap.

The CLCA1/TMEM16A/Cl- current axis associates with H2S deficiency in diabetic kidney injury.

The role played by anionic channels in diabetic kidney disease (DKD) is not known. Chloride channel accessory 1 (CLCA1) facilitates the activity of TMEM16A (Anoctamin-1), a Ca2+-dependent Cl- channel. We examined if CLCA1/TMEM16A had a role in DKD.

Dementia Care Research and Psychosocial Factors.

Background: Commonly used screening measures of cognitive function such as the Montreal Cognitive Assessment (MoCA) are not sensitive to assess cognitive function among individuals with severe cognitive impairment due to floor effect. The Severe Cognitive Impairment Rating Scale (SCIRS) was designed to assess cognitive function in those with severe cognitive impairment, however, psychometric properties of its English version have not been reported.

Method: Using the existing data from StaN and tTED studies, floor and ceiling effects (percentage of minimal or maximal scores) of SCIRS and MoCA were examined, and the association between SCIRS and MoCA was evaluated.

Gender bias in acute myocardial infarction care in India: Nationwide retrospective study of 41832 patients.

Background: Various studies have documented gender differences in the management and outcomes of acute myocardial infarction (AMI) in developed countries. Gender differences in the management of AMI in India is not known.

Objectives: To document the gender differences in the management and outcomes of AMI in India.
