After mild traumatic brain injury (mTBI), a subgroup of individuals experience persistent post-concussion symptoms (PPCS) that include headaches, cognitive difficulties, and fatigue. The aim of this preliminary study was to investigate possible effects associated with metacognitive therapy (MCT) on PPCS, maladaptive coping strategies, and positive and negative metacognitive beliefs following mTBI. A pre-post design supplemented with single-case A-B replication series to assess potential MCT mechanisms was used.

Article Synopsis
  • Adverse psychosocial factors like stress and loneliness can affect gene expression related to inflammation and cognitive decline, suggesting that people facing these challenges may experience higher levels of CTRA gene expression.
  • In participants with normal cognition and mild cognitive impairment (MCI), a sense of eudaimonic well-being (EWB) was linked to lower levels of CTRA gene expression, indicating its potential protective role against stress.
  • Coping strategies varied based on cognitive status, influencing the relationship with CTRA gene expression, while loneliness did not significantly affect gene expression in this low-loneliness group.

PET/CT/MRI in Clinical Trials of Alzheimer's Disease.

J Alzheimers Dis

October 2024

Department of Molecular and Medical Pharmacology, David Geffen UCLA School of Medicine, Los Angeles, CA, USA.

With the advent of PET imaging in 1976, 2-deoxy-2-[18F]fluoro-D-glucose (FDG)-PET became the preferred method for in vivo investigation of cerebral processes, including regional hypometabolism in Alzheimer's disease. With the emergence of amyloid-PET tracers, [11C]Pittsburgh Compound-B in 2004 and later [18F]florbetapir, [18F]florbetaben, and [18F]flumetamol, amyloid-PET has replaced FDG-PET in Alzheimer's disease anti-amyloid clinical trial treatments to ensure "amyloid positivity" as an entry criterion, and to measure treatment-related decline in cerebral amyloid deposits. MRI has been used to rule out other brain diseases and screen for 'amyloid-related imaging abnormalities' (ARIAs) of two kinds, ARIA-E and ARIA-H, characterized by edema and micro-hemorrhage, respectively, and, to a lesser extent, to measure changes in cerebral volumes.

Background: infection (CDI) may be misdiagnosed if testing is performed in the absence of signs or symptoms of disease. This study sought to support appropriate testing by estimating the impact of signs, symptoms, and healthcare exposures on pre-test likelihood of CDI.

Methods: A panel of fifteen experts in infectious diseases participated in a modified UCLA/RAND Delphi study to estimate likelihood of CDI.

Article Synopsis
  • The study explores how deuterium levels in the body can impact health, specifically looking at deuterium-depleted water and diets as potential aids.
  • Research indicates that reducing deuterium may offer health benefits for various conditions like cancer, depression, diabetes, and enhancing athletic performance.
  • The authors recommend further research, especially randomized control trials, to better understand the effects of deuterium depletion on health outcomes and to improve nutritional interventions.

Article Synopsis
  • High body-mass index (BMI) impacts cognitive function in older adults, but most research is from wealthy countries; studies from low- and middle-income countries show inconsistent results.
  • Using data from the Longitudinal Aging Study in India with over 56,000 participants, the study found that underweight individuals scored lower in cognitive tests, while overweight and obese individuals scored higher.
  • The relationship between BMI and cognition varied by urban living and education levels, suggesting that underweight may indicate nutritional deficits and socio-economic disadvantages, particularly for those aged 45 and older in India.

Objective: Grit is a person's ability to establish long-term goals and work to achieve those goals irrespective of any barriers. We examined the relationship between the personality trait grit, obesity, and metabolic and bariatric surgery (MBS)-induced weight loss.

Methods: In an ongoing prospective cohort, 104 adult patients who underwent laparoscopic sleeve gastrectomy (LSG) had preoperative grit questionnaires administered.

Resilience Intervention Improves Stress-Related Gene Expression in Adolescent and Young Adult HCT Recipients.

December 2024

Overactivation of the stress response can influence cancer outcomes through immune-related pathways. Adolescents and young adults (AYAs) undergoing hematopoietic cell transplantation (HCT) are at risk for poor outcomes, yet there are limited behavioral interventions and no psychosocial biomarker data for this population. The Conserved Transcriptional Response to Adversity (CTRA) is an inflammation-related pattern observed in conditions of heightened stress and is associated with HCT outcomes.

Background: Sex differences in immune-based disorders are well-established, with female sex associated with a markedly heightened risk of autoimmune disease. Female sex is also overrepresented in other conditions associated with elevated inflammation, including depression, chronic pain, and chronic fatigue. The mechanisms underlying these disparities are unclear.

The goal of this study was to assess the feasibility of using exome (ES) and genome sequencing (GS) in guiding preconception genetic screening (PCGS) for couples who are planning to conceive by creating a workflow for identifying risk alleles for autosomal recessive (AR) and X-linked (XL) disorders without the constraints of a predetermined, targeted gene panel. There were several limitations and challenges related to reporting and the technical aspects of ES and GS, which are listed in the discussion. We selected 150 couples from a cohort of families (trios) enrolled in a research protocol where the goal was to define the genetic etiology of disease in an affected child.
