Polygenic risk scores across the extended psychosis spectrum

Translational Psychiatry, 2021
As early detection of symptoms in the subclinical to clinical psychosis spectrum may improve health outcomes, knowing the probabilistic susceptibility of developing a disorder could guide mitigation measures and clinical intervention.

Robust Method for Non-Contact Vital Sign Measurement in Videos Acquired in Real-World Light Settings From Skin Less Affected by Blood Perfusion

IEEE Access
Color fluctuations caused by blood perfusion on the skin are an essential tool for the success of imaging photoplethysmography (iPPG) methods. However, color fluctuation of the non-facial skin is less observable than that of the facial skin. Furthermore,

The International Consortium of Lithium Genetics (ConLiGen): Achievements and Collaborations

Обозрение психиатрии и медицинской психологии имени В.М. Бехтерева, 2019
Lithium is an indispensable tool of modern psychiatry. Although it is well-known that response to lithium is a familial trait, available research on pharmacogenetics regarding lithium treatment has, in the past, produced few reproducible results.

The Interaction of Polygenic Susceptibility to Stress and Childhood Adversity Dimensions Predicts Longitudinal Trajectories of Stress‐Sensitivity

Stress and Health, Volume 40, Issue 6, December 2024.
ABSTRACT Stress‐sensitivity (SS) is considered a psychobiological trait possibly resulting from the interaction of genetic and environmental factors (GxE). This study examined whether the interaction of SS‐related genetic markers with interview‐based dimensions of childhood adversity predicted longitudinal trajectories of low versus high SS ...

First noncontact millimeter‐wave radar measurement of heart rate in great apes: Validation in chimpanzees (Pan troglodytes)

American Journal of Primatology, Volume 86, Issue 8, August 2024.
We observed a remarkable correspondence between the peak frequency spectrum of heart rate estimated using millimeter‐wave radar and the mean value obtained from electrocardiograph data, thereby validating the accuracy of the method. Abstract Heart rate is a crucial vital sign and a valuable indicator for assessing the physical and psychological ...

Motion-compensated noncontact imaging photoplethysmography to monitor cardiorespiratory status during exercise [PDF]

, 2011
With the advance of computer and photonics technology, imaging photoplethysmography [(PPG), iPPG] can provide comfortable and comprehensive assessment over a wide range of anatomical locations. However, motion artifact is a major drawback in current iPPG

Latin American Trans‐ancestry INitiative for OCD genomics (LATINO): Study protocol

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, Volume 195, Issue 4, June 2024.
Abstract Obsessive‐compulsive disorder (OCD) is a debilitating psychiatric disorder. Worldwide, its prevalence is ~2% and its etiology is mostly unknown. Identifying biological factors contributing to OCD will elucidate underlying mechanisms and might contribute to improved treatment outcomes.
