The association between pre-pregnancy and first-trimester hair cortisol and preterm birth: a causal inference model.

Adverse life events and chronic psychological distress before and during pregnancy have frequently been associated with preterm birth but the biological underpinnings remain unclear. We investigated the association between corticosteroid levels in pre-pregnancy and first-trimester hair and the risk of preterm birth. We followed N = 1,807 pregnant women from a prospective pre-birth cohort study in Lima, Perú.

Alopecia Areata Is Associated with Posttraumatic Stress Disorder and Alcohol Use in a Case-Control Study of 4,785 Patients.

Introduction: Previous studies have demonstrated association of alopecia areata (AA) with anxiety and depression. However, few case-control studies have evaluated AA association with posttraumatic stress disorder and lifestyle factors, including alcohol use. We aimed to assess associations of AA with psychiatric disorders and lifestyle factors using a national database.

Prenatal exposure to selective serotonin reuptake inhibitors and risk of disorders of gut-brain interaction in children.

Preclinical data suggest that gestational exposure to selective serotonin reuptake inhibitors (SSRI) alter gut innervation, and delays colonic motility. In this study we investigated associations between gestational SSRI exposure and offspring disorders of gut-brain interaction (DGBI). Using population-based registries, we included all single-birth Danish children born 1997-2015 with follow-up until outcome occurrence, age 15 years, death, emigration, or December 2018.

Research Priorities for Autonomous Sensory Meridian Response: An Interdisciplinary Delphi Study.

Autonomous Sensory Meridian Response (ASMR) is a multisensory experience most often associated with feelings of relaxation and altered consciousness, elicited by stimuli which include whispering, repetitive movements, and close personal attention. Since 2015, ASMR research has grown rapidly, spanning disciplines from neuroscience to media studies but lacking a collaborative or interdisciplinary approach. To build a cohesive and connected structure for ASMR research moving forwards, a modified Delphi study was conducted with ASMR experts, practitioners, community members, and researchers from various disciplines.

Olfactory function is reduced in a subset of former elite American football players with traumatic encephalopathy syndrome.

Former American football players are at risk for developing traumatic encephalopathy syndrome (TES), the clinical disorder associated with neuropathologically diagnosed chronic traumatic encephalopathy (CTE). The objective of this study was to determine whether hyposmia is present in traumatic encephalopathy syndrome. The study included 119 former professional American football players, 60 former college football players, and 58 same-age asymptomatic unexposed men from the DIAGNOSE CTE Research Project.

The influence of early childhood education and care on the relation between early-life social adversity and children's mental health in the environmental influences for Child Health Outcomes Program.

Early adversity increases risk for child mental health difficulties. Stressors in the home environment (e.g.

Fielding the research participant perception survey to evaluate a culturally tailored Latinx cohort study.

Introduction: Latinx populations are underrepresented in clinical research. Asking Latinx research participants about their research experiences, barriers, and facilitators could help to improve research participation for these populations.

Methods: The Salud Estres y Resilencia (SER) Hispano cohort study is a longitudinal cohort study of young adult Latinx immigrants whose design and conduct were tailored for their study population.

Feasibility of Utilizing a Brief Neurocognitive Battery in 3-Year-Old Patients During Treatment for Acute Lymphoblastic Leukemia.

Treatment of acute lymphoblastic leukemia (ALL) is associated with neurocognitive deficits in young children. While computerized measures have been utilized in pediatric oncology research, they exclude patients below the age of 4 years. Patients enrolled on "Treatment of Newly Diagnosed Acute Lymphoblastic Leukemia in Children and Adolescents" were offered participation in an optional neurocognitive study.

A framework for neural organoids, assembloids and transplantation studies.

As the field of neural organoids and assembloids rapidly expands, there is an emergent need for guidance and advice on designing, conducting and reporting experiments to increase the reproducibility and utility of these models. Here, our consortium- representing specialized laboratories from around the world- presents a framework for the experimental process that ranges from ensuring the quality and integrity of human pluripotent stem cells to characterizing and manipulating neural cells in vitro, and from transplantation techniques to considerations for modeling human development, evolution, and disease. As with all scientific endeavors, we advocate for rigorous experimental designs tailored to explicit scientific questions, and transparent methodologies and data sharing, to provide useful knowledge for both current research practices and for developing regulatory standards.

Factors associated with PrEP awareness and use among men who have sex with men who use drugs in the Southern United States.

Pre-exposure prophylaxis (PrEP) dramatically reduces HIV transmission risk. PrEP is underutilized among men who have sex with men who use substances (SU-MSM) in the Southern U.S.

Translation and cross-cultural adaptation of a portuguese version of the eating disorder assessment for DSM-5 (EDA-5) for Brazil and Portugal.

The EDA-5 was translated from English to Portuguese, followed by a cross-cultural adaptation for use in Brazil and Portugal. Two independent translators worked on the Brazilian and European Portuguese versions, which were then reviewed to create a harmonized version. This version was back-translated into English and approved by the original author.

BMI Interacts with the Genome to Regulate Gene Expression Globally, with Emphasis in the Brain and Gut.

Genome-wide association studies identify common genomic variants associated with disease across a population. Individual environmental effects are often not included, despite evidence that environment mediates genomic regulation of higher order biology. Body mass index (BMI) is associated with complex disorders across clinical specialties, yet has not been modeled as a genomic environment.

Convergent molecular signatures across eating disorders and obsessive-compulsive disorder in the human brain.

Eating disorders (ED) and obsessive-compulsive disorder (OCD) exhibit significant clinical and genetic overlap, yet their shared molecular mechanisms remain unclear. We conducted a transcriptomic investigation of the dorsolateral prefrontal cortex (DLPFC) and caudate from 86 controls, 57 ED, and 27 OCD cases. ED was associated with robust differentially expressed genes (DEGs): 102 DEGs the DLPFC and 222 in the caudate (FDR < 1%) and replicated in an independent cohort.

A Preliminary Pharmacokinetic Comparison of Δ-9 Tetrahydrocannabinol and Cannabidiol Extract Versus Oromucosal Spray in Healthy Men and Women.

Few studies have directly compared the bioavailability of different cannabinoid formulations. Our goal was to assess the pharmacokinetic parameters and relative bioavailability of two Δ9-tetrahydrocannabinol:cannabidiol (THC:CBD) formulations: orally administered THC:CBD extract and oromucosally administered nabiximols. This pilot crossover study counterbalanced (1) 1 mL of orally administered THC:CBD extract (10 mg/mL each of THC and CBD in grapeseed oil) and (2) oromucosally administered nabiximols (four sprays of 2.

Elevated IL-22 as a result of stress-induced gut leakage suppresses septal neuron activation to ameliorate anxiety-like behavior.

Psychological stress and its sequelae pose a major challenge to public health. Immune activation is conventionally thought to aggravate stress-related mental diseases such as anxiety disorders and depression. Here, we sought to identify potentially beneficial consequences of immune activation in response to stress.

Mapping the microRNA landscape in the older adult brain and its genetic contribution to neuropsychiatric conditions.

MicroRNAs (miRNAs) play a crucial role in regulating gene expression and influence many biological processes. Despite their importance, understanding of how genetic variation affects miRNA expression in the brain and how this relates to brain disorders remains limited. Here we investigated these questions by identifying microRNA expression quantitative trait loci (miR-QTLs), or genetic variants associated with brain miRNA levels, using genome-wide small RNA sequencing profiles from dorsolateral prefrontal cortex samples of 604 older adult donors of European ancestry.

Remote monitoring of social attention in neurogenetic syndromes and idiopathic neurodevelopmental disability.

Social attention is a key aspect of neurodevelopment and is significantly altered in neurodevelopmental genetic syndromes and many individuals with idiopathic autism spectrum disorder (ASD). The primary aim of the present study was to examine the psychometric properties of webcam-collected social attention measurements, including four new specific aspects of social attention, in three genetic syndromes (PTEN Hamartoma Tumor Syndrome-PHTS; Malan Syndrome-NFIX; and SYNGAP1-related disorder-SYNGAP1), a mixed group of other neurodevelopmental genetic syndromes (Other NDGS), and individuals with a range of idiopathic neurodevelopmental disorder (NDD). The secondary aim was to evaluate the construct validity of these social attention measurements, including evaluating known-groups validity across study groups and concurrent validity for separating ASD and non-ASD cases.
