Association of Self-Reported Autonomic Symptoms With Sensor-Based Physiological Measures.

Objective: Autonomic regulation of organ and tissues may give rise to disruptions of typical functions. The Body Perception Questionnaire Short Form (BPQ-SF) includes items that were developed to assess autonomic symptoms in daily life. This pair of studies aimed to establish previously unexplored psychometric properties of the BPQ-SF autonomic symptoms scale, develop normative values for clinical and research use, and assess the convergence of self-reports with sensor-based measures.

Predictors of Participation for Sexuality Items in a U.S. Population-Based Online Survey.

Online surveys are a popular tool in sex research and it is vital to understand participation bias in these surveys to improve inferences. However, research on this topic is limited and out of date given the increase in online survey methodology and changes in sexual attitudes. This study examined whether demographics and sexual abuse and assault history predict opting into online survey questions about sex.

Cardiac autonomic regulation and joint hypermobility in adolescents with functional abdominal pain disorders.

Background: Joint hypermobility (JH) is associated with autonomic nervous system dysregulation and functional abdominal pain disorders (FAPDs). Understanding the neurophysiological processes linking these conditions can inform clinical interventions. Autonomic activity regulates gastrointestinal (GI) sensorimotor function and may be a key mechanism.

Adversity History Predicts Self-Reported Autonomic Reactivity and Mental Health in US Residents During the COVID-19 Pandemic.

The spread of the COVID-19 virus presents an unprecedented event that rapidly introduced widespread life threat, economic destabilization, and social isolation. The human nervous system is tuned to detect safety and danger, integrating body and brain responses via the autonomic nervous system. Shifts in brain-body states toward danger responses can compromise mental health.

Prospective randomized placebo-controlled trial of aprotinin for elective aortic reconstruction.

Background: The serine protease antagonist, aprotinin, reduces perioperative blood loss in cardiac surgery and orthotopic liver transplantation. A pilot study suggested that the drug may also reduce bleeding during infrarenal aortic replacement; the aim was to confirm or refute this observation with a prospective, randomized, double-blind, placebo-controlled trial.

Methods: Some 136 patients were randomized to receive either aprotinin, given as a loading dose of 2 x 10(6) kallikrein inactivator (KI) units followed by 0.
