BACKGROUND: Management of keloids has remained a conundrum, because an optimum treatment regimen has yet to be elucidated. Currently, treatment varies widely between more conservative measures, such as steroid injections, topical medications, and silicone sheeting, to more aggressive options, such as surgery and postoperative radiation. The latter combination has been touted to have superior results, with the lowest rates of pathologic scar recurrence. METHODS: We performed a retrospective review to critically evaluate the effectiveness of surgical excision and radiation treatment in patients with keloids...

: Although surveillance ultrasound and alpha fetoprotein (AFP) have minimal direct harm, downstream harms from follow-up tests must be weighed against surveillance benefits when determining the value of hepatocellular carcinoma (HCC) screening programs. Our study's aims were to characterize prevalence and correlates of surveillance benefits and harms in cirrhosis patients undergoing HCC surveillance. We conducted a retrospective cohort study among patients with cirrhosis followed at a safety-net health system between July 2010 and July 2013...

Depth image acquisition with structured light approaches in outdoor environments is a challenging problem due to external factors, such as ambient sunlight, which commonly affect the acquisition procedure. This paper presents a novel structured light sensor designed specifically for operation in outdoor environments. The sensor exploits a modulated sequence of structured light projected onto the target scene to counteract environmental factors and estimate a spatial distortion map in a robust manner. The correspondence between the projected pattern and the estimated distortion map is then established using a probabilistic framework based on graphical models...

When humans are asked to palpate a soft tissue to locate a hard nodule, they regulate the stiffness, speed, and force of the finger during examination. If we understand the relationship between these behavioral variables and haptic information gain (transfer entropy) during manual probing, we can improve the efficacy of soft robotic probes for soft tissue palpation, such as in tumor localization in minimally invasive surgery. Here, we recorded the muscle co-contraction activity of the finger using EMG sensors to address the question as to whether joint stiffness control during manual palpation plays an important role in the haptic information gain...

Objective: We aimed to assess the extent to which therapists' reports of client functioning track their clients' changing experience of their own functioning from session to session (temporal congruence) as well as the extent to which they over- or underestimate their clients' functioning (level or directional bias) and to examine whether these indices predict treatment outcomes. Method: The participants included 384 clients who were treated by 77 therapists. Both clients and therapists rated the clients' functioning each session...

We investigated how group membership impacts valence judgments of ingroup and outgroup members' emotional expressions. In Experiment 1, participants, randomized into 2 novel, competitive groups, rated the valence of in- and outgroup members' facial expressions (e.g., fearful, happy, neutral) using a circumplex affect grid. Across all emotions, participants judged ingroup members' expressions as more positive than outgroup members' expressions. In Experiment 2, participants categorized fearful and happy expressions as being either positive or negative using a mouse-tracking paradigm...

Homesickness can put individuals at risk for a host of adjustment difficulties. The millions of students that leave home for college each year may be particularly susceptible to experiencing homesickness. There is little work, however, examining individual variation in homesickness over time and how these changes predict different outcomes in college. The present study examines weekly levels of homesickness during the first term of college and tests the associations between homesickness and various aspects of adjustment...

We report new evidence on the emotional, demographic, and situational correlates of boredom from a rich experience sample capturing 1.1 million emotional and time-use reports from 3,867 U.S. adults. Subjects report boredom in 2.8% of the 30-min sampling periods, and 63% of participants report experiencing boredom at least once across the 10-day sampling period. We find that boredom is more likely to co-occur with negative, rather than positive, emotions, and is particularly predictive of loneliness, anger, sadness, and worry...

As speakers interact, they add references to their common ground, which they can then reuse to facilitate listener comprehension. However, all references are not equally likely to be reused. The purpose of this study was to shed light on how the speakers' conceptualizations of the referents under discussion affect reuse (along with a generation effect in memory documented in previous studies on dialogic reuse). Two experiments were conducted in which participants interactively added references to their common ground...

In order to investigate the role of differential adaptation for the evolution of reproductive barriers, we conducted a multi-site transplant experiment with the dioecious sister species Silene dioica and S. latifolia and their hybrids. Crosses within species as well as reciprocal first-generation (F1 ) and second-generation (F2 ) interspecific hybrids were transplanted into six sites, three within each species' habitat. Survival and flowering were recorded over 4 yr. At all transplant sites, the local species outperformed the foreign species, reciprocal F1 hybrids performed intermediately and F2 hybrids underperformed in comparison to F1 hybrids (hybrid breakdown)...

Neural interface technologies including recording and stimulation electrodes are currently in the early phase of clinical trials aiming to help patients with spinal cord injuries, degenerative disorders, strokes interrupting descending motor pathways, or limb amputations. Their lifetime is of key importance; however, it is limited by the foreign body response of the tissue causing the loss of neurons and a reactive astrogliosis around the implant surface. Improving the biocompatibility of implant surfaces, especially promoting neuronal attachment and regeneration is therefore essential...

OBJECTIVE: Chronic suppurative otitis media is a neglected condition affecting up to 330 million people worldwide, with the burden of the disease in impoverished countries. The need for non-governmental organisations to hardwire training into their programmes has been highlighted. An ear surgery simulator appropriate for training in resource-poor settings was developed, and its effectiveness in facilitating the acquisition of headlight and microsurgical skills necessary to safely perform procedures via the ear canal was investigated...

OBJECTIVE: Despite declines in Australian alcohol consumption, youth alcohol related harms remain prevalent. These alcohol-related consequences appear to be driven by a subset of risky drinkers who engage in 'high intensity' drinking episodes and are underrepresented in national health surveys. This project aims to investigate high risk drinking practices and alcohol-related harms amongst young people not otherwise recorded in existing data. METHODS: A community sample of the heaviest drinking 20-25% 16-19 year olds were surveyed across three Australian states (n=958; 80% metropolitan)...

We have previously reported that GR-1 neutrophil/monocytes rose dramatically in the spleen, peaked by day 7 and declined through day 14. This period corresponded to the peak of acute Graft-Versus-Host Disease (aGVHD) in BALB/c mice transplanted with allogeneic donor cells. We now asked: what cytokines did these splenic neutrophil/monocytes express on day 7 and 14 post transplant? BALB/c mice were transplanted with allogeneic B6 or syngeneic BALB/c donor cells. Long term survival was recorded through day 31...

The synergistic effects were evaluated during the oxidation of carbamazepine using a sono-electrochemical process. The sono-electrochemical oxidation was performed using two types of experimental units (having 1L and 100L of working volume, respectively) and containing one anode (Ti/PbO2) and one cathode (Ti). Different operating parameters, including power of ultrasounds, current intensity and reaction time were investigated. The degree of synergy increased when the current intensity decreased, whereas it increased with the power of ultrasounds imposed...

BACKGROUND: Current surgical education relies on simulated educational experiences or didactic sessions to teach low-frequency clinical events such as abdominal compartment syndrome (ACS). The purpose of this pilot study was to evaluate if simulation would improve performance and knowledge retention of ACS better than a didactic lecture. METHODS: Nineteen general surgery residents were block randomized by postgraduate year level to a didactic or a simulation session...

Animals living in aquatic habitats regularly encounter anthropogenic chemical pollution. Typically, the toxicity of a chemical toxicant is determined by the median lethal concentration (LC50) through a static exposure test. However, LC50 values and static tests do not provide an accurate representation of exposure to pollutants within natural stream systems. In their native habitats, animals experience exposure as a fluctuating concentration due to turbulent mixing, temporal variations of contamination (seasonal inputs), and contaminant input type (point vs...
