To examine whether acute changes in cognitive empathy might mediate the impact of light therapy on mood, we assessed the effects of a single light-therapy session on mood and cognitive empathy in 48 premenstrual women, including 17 who met Premenstrual Symptoms Screening Tool criteria for moderate-to-severe premenstrual syndrome / premenstrual dysphoric disorder (PMS/PMDD). Using a participant-blind between-groups design, 23 women underwent 30min of morning light therapy (5,000lx; blue-enriched polychromatic light, 17,000K) while 25 women had a sham session (200lx, polychromatic light, 5,000K)...

S M Schellong, N Abolmaali, B Voigts, C Stelzner
Nowadays, several technically validated modalities are available for imaging both the extracranial and intracranial segments of arteries supplying blood to the brain. In the acute stroke setting, computed tomography (CT) angiography is of utmost importance because it provides the key diagnostic criteria indicative for the use of catheter-based recanalization techniques. Ultrasound imaging of extracranial arteries is most suitable for detecting an underlying stenosis of the internal carotid artery (ICA) in patients with stroke, transient ischemic attacks (TIA), retinal vessel occlusion and amaurosis fugax...

OJECTIVE: Ultrasound guided central venous catheterization (CVC) is a common surgical procedure with complication rates ranging from 5 to 21 percent. Training is typically performed using manikins that do not simulate anatomical variations such as obesity and abnormal vessel positioning. The goal of this study was to develop and validate the effectiveness of a new virtual reality and force haptic based simulation platform for CVC of the right internal jugular vein. DESIGN: A CVC simulation platform was developed using a haptic robotic arm, 3D position tracker, and computer visualization...

BACKGROUND: One in five recently deployed U.S. women veterans report overactive bladder symptoms. Mental health conditions such as depression and anxiety commonly co-occur in women with overactive bladder, but temporal relationships between these outcomes have not been well-studied, and the mechanism behind this association is unknown. The Women Veterans Urinary Health Study, a nationwide longitudinal study in recently deployed women veterans, was designed to better understand relationships between overactive bladder and mental health conditions...

BACKGROUND: Adolescents spend many hours in sitting activities as television viewing, video game playing and computer use. The relationship between sedentary behavior and respiratory health remains poorly elucidated. To date there have been no studies evaluating the relationship between sedentary behavior and pulmonary function in young populations. The purpose of this study is to examine the association between the trajectory of screen-based sedentary behavior from 11 to 18 years and pulmonary function at 18 years in a Brazilian birth cohort...

Endocrine disruptors, especially estrogen receptor (ER) agonists, have received considerable research attention. While there are several mechanistic endpoints for ER agonism in the Endocrine Disruptor Screening Program, there have been growing efforts to develop high-throughput screening assays and computational models to reduce testing cost, time, and animal use. For example, there are 16 ER agonist assays and an integrated computational model in ToxCast. In the present study, we examined the relationship between ToxCast ER agonist assays and model activity to male vitellogenin induction in the Fish-Short Term Reproduction Assay...

Zhangkai Ni, Lin Ma, Huanqiang Zeng, Jing Chen, Canhui Cai, Kai-Kuang Ma
In this paper, an accurate full-reference image quality assessment (IQA) model developed for assessing screen content images (SCIs), called the edge similarity (ESIM), is proposed. It is inspired by the fact that the human visual system (HVS) is highly sensitive to edges that are often encountered in SCIs; therefore, essential edge features are extracted and exploited for conducting IQA for the SCIs. The key novelty of the proposed ESIM lies in the extraction and use of three salient edge features-i.e., edge contrast, edge width, and edge direction...

Purpose This study estimated the 10-year risk of developing second primary lung cancer (SPLC) among survivors of initial primary lung cancer (IPLC) and evaluated the clinical utility of the risk prediction model for selecting eligibility criteria for screening. Methods SEER data were used to identify a population-based cohort of 20,032 participants diagnosed with IPLC between 1988 and 2003 and who survived ≥ 5 years after the initial diagnosis. We used a proportional subdistribution hazards model to estimate the 10-year risk of developing SPLC among survivors of lung cancer LC in the presence of competing risks...

INTRODUCTION: Although it is not rare for magnetic resonance imaging findings in Creutzfeldt-Jakob disease to be asymmetric, unilateral clinical syndromes are uncommonly reported and may confound diagnosis. In addition, neurological paraneoplastic syndromes are not common in renal cell carcinoma, though there are cases reported, often without an offending antibody isolated. CASE REPORT: A 66-year-old man was admitted with 1 month of left-sided numbness and "loss of control" of the left arm...

GOAL: Chest auscultations offer a non-invasive and low-cost tool for monitoring lung disease. However, they present many shortcomings including inter-listener variability, subjectivity, and vulnerability to noise and distortions. The current work proposes a computer-aided approach to process lung signals acquired in the field under adverse noisy conditions, by improving the signal quality and offering automated iden- tification of abnormal auscultations indicative of respiratory pathologies...

One of the biggest problems of upper limb transplantation is lack of certainty as to whether a patient will be able to control voluntary movements of transplanted hands. Based on findings of the recent research on brain cortex plasticity, a premise can be drawn that mental training supported with visual and sensory feedback can cause structural and functional reorganization of the sensorimotor cortex, which leads to recovery of function associated with the control of movements performed by the upper limbs. In this study, authors - based on the above observations - propose the computer-aided training (CAT) system, which generating visual and sensory stimuli, should enhance the effectiveness of mental training applied to humans before upper limb transplantation...

Screening for lung cancer using low-dose computed tomography (LDCT) has been demonstrated to reduce lung cancer-related mortality and is being widely implemented. Further research in this area is needed to assess the impact of screening on patient-centered outcomes. Here we describe the design and rationale for a new study entitled Lung Cancer Screening Implementation: Evaluation of Patient-Centered Care. The protocol is composed of an interconnected series of studies evaluating patients and clinicians who are engaged in lung cancer screening in real-world settings...

BACKGROUND: People who suffer from paralysis have difficulties participating in society. Particularly burdensome is the locked-in syndrome (LIS). LIS patients are not able to move and speak but are cognitively healthy. They rely on assistive technology to interact with the world and may benefit from neurotechnological advances. Optimal research and design of such aids requires a well-defined target population. However, the LIS population is poorly characterized and the number of patients in this condition is unknown...

BACKGROUND: In 2013, the US Preventive Services Task Force (USPSTF) began recommending lung cancer screening for high risk smokers aged 55-80 years using low-dose computed tomography (CT) scan. In light of these updated recommendations, there is a need to understand smokers' knowledge of and experiences with lung cancer screening in order to inform the design of patient education and tobacco cessation programs. The purpose of this study is to describe results of a qualitative study examining smokers' perceptions around lung cancer screening tests...
