Misinformation effects in an online sample: results of an experimental study with a five day retention interval.

Traditional face-to-face laboratory studies have contributed greatly to our understanding of how misinformation effects develop. However, an area of emerging concern that has been relatively under-researched is the impact of misinformation following exposure to traumatic events that are viewed online. Here we describe a novel method for investigating misinformation effects in an online context.

Respiratory alkalinization and posterior cerebral artery dilatation predict acute mountain sickness severity during 10 h normobaric hypoxia.

New Findings: What is the central question of this study? The pathophysiology of acute mountain sickness (AMS), involving the respiratory, renal and cerebrovascular systems, remains poorly understood. How do the early adaptations in these systems during a simulated altitude of 5000 m relate to AMS risk? What is the main finding and its importance? The rate of blood alkalosis and cerebral artery dilatation predict AMS severity during the first 10 h of exposure to a simulated altitude of 5000 m. Slow metabolic compensation by the kidneys of respiratory alkalosis attributable to a brisk breathing response together with excessive brain blood vessel dilatation might be involved in early development of AMS.

Trichotillomania: Demographic and Clinical Features From a Nationally Representative US Sample.

Trichotillomania (TTM) is a psychodermatologic disorder that is typically first seen in the dermatology clinic. There are no reported studies of TTM from nationally representative samples. The authors examined epidemiologic and clinical characteristics of an estimated 695,588±136,456 (unweighted count = 89) patient visits with physician-diagnosed TTM (using International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code 312.

Cardiovascular and psychiatric morbidity in obstructive sleep apnea (OSA) with insomnia (sleep apnea plus) versus obstructive sleep apnea without insomnia: a case-control study from a Nationally Representative US sample.

Purpose: To evaluate cardiovascular and psychiatric morbidity in patient visits with obstructive sleep apnea (OSA) with insomnia (OSA+Insomnia) versus OSA without insomnia (OSA-Insomnia) in a nationally representative US sample.

Methods: A retrospective case-control study of epidemiologic databases (National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey) representing an estimated ± standard error (SE) 62,253,910 ± 5,274,747 (unweighted count=7234) patient visits with diagnosis of OSA from 1995-2010, was conducted. An estimated 3,994,104 ± 791,386 (unweighted count=658) were classified as OSA+Insomnia and an estimated 58,259,806 ± 4,849,800 (unweighted count=6576) as OSA-Insomnia.

Dissatisfaction with cutaneous body image is directly correlated with insomnia severity: A prospective study in a non-clinical sample.

Objectives: Sleep deprivation can physically affect skin appearance, e.g. increase the cutaneous signs of aging.

Trajectories and predictors of symptom occurrence, severity, and distress in prostate cancer patients undergoing radiation therapy.

Context: Radiation therapy (RT) is a common treatment for prostate cancer. Despite available research, prostate cancer patients report that information about side effects is their most important unmet need. Additional research is needed that focuses on specific dimensions of the patient's symptom experience.

Routes to the past: neural substrates of direct and generative autobiographical memory retrieval.

Models of autobiographical memory propose two routes to retrieval depending on cue specificity. When available cues are specific and personally-relevant, a memory can be directly accessed. However, when available cues are generic, one must engage a generative retrieval process to produce more specific cues to successfully access a relevant memory.
