Keloids are benign cutaneous lesions, arising from proliferating fibroblasts. Keloids of the ear may occur after trauma, surgery or helix piercings and are difficult to treat, since they tend to form recurrences. Guidelines suggest multimodal therapy; however, recurrence rates remain high and distinct algorithms for the combination of different modalities are missing. To unravel the most effective combination of therapeutic options for keloids of the ear, 38 patients with the diagnosis of an ear keloid were included in our cohort...

Disorders of chloride and mixed acid-base disturbances are common in veterinary emergency medicine. Rapid identification of these alterations and the presence of unmeasured anions aid prompt patient assessment and management. This study aimed to determine in dogs and cats if site-specific reference values for [Cl(-)]:[Na(+)] ratio and [Na(+)] - [Cl(-)] difference accurately identify corrected chloride abnormalities and to evaluate the predictive ability of the [Cl(-)]:[Na(+)] ratio for the identification of unmeasured anions...

Posttraumatic stress disorder (PTSD) is a reaction to trauma that results in a chronic perception of threat, precipitating mobilization of the autonomic nervous system, and may be reflected by chronic disinhibition of limbic structures. A common injury preceding PTSD in veterans is mild traumatic brain injury (mTBI). This may be due to the vulnerability of white matter in these networks and such damage may affect treatment response. We evaluated transcutaneous vagal nerve stimulation (tVNS), a non-invasive, low-risk approach that may alter the functions of the limbo-cortical and peripheral networks underlying the hyperarousal component of PTSD and thus improve patient health and well-being...

To elucidate promoting and inhibiting effects of hydrogen cynamide (HC) and abscisic acid (ABA) on quiescence release of grape buds, physiological and molecular approaches were used to explore the mechanisms of quiescence based on metabolic and gene expression analysis. Physiological and molecular mechanisms involved in bud quiescence of grape were studied before and after application of HC, ABA, and ABA-HC. The data showed that ABA inhibited proclamation of quiescence in grape buds and attenuated the influence of HC...

Whole Genome Shotgun (WGS) sequences of plant species often contain an abundance of reads that are derived from the chloroplast genome. Up to now these reads have generally been identified and assembled into chloroplast genomes based on homology to chloroplasts from related species. This re-sequencing approach may select against structural differences between the genomes especially in non-model species for which no close relatives have been sequenced before. The alternative approach is to de novo assemble the chloroplast genome from total genomic DNA sequences...

The Internet is subject to attacks due to vulnerabilities in its routing protocols. One proposed approach to attain greater security is to cryptographically protect network reachability announcements exchanged between Border Gateway Protocol (BGP) routers. This study proposes and evaluates the performance and efficiency of various optimization algorithms for validation of digitally signed BGP updates. In particular, this investigation focuses on the BGPSEC (BGP with SECurity extensions) protocol, currently under consideration for standardization in the Internet Engineering Task Force...

INTRODUCTION: Misophonia is a recently described, poorly understood and neglected condition. It is characterized by strong negative reactions of hatred, anger or fear when subjects have to face some selective and low level repetitive sounds. The most common ones that trigger such aversive reactions are those elicited by the mouth (chewing gum or food, popping lips) or the nose (breathing, sniffing, and blowing) or by the fingers (typing, kneading paper, clicking pen, drumming on the table)...

Patients with HIV infection have a higher cardiovascular risk than the general population. The identification of patients with high CVR, the implementation of preventive measures and the control of modifiable risk factors, especially in patients on antiretroviral therapy should be part of the management of HIV infection. This document updates the recommendations published in 2014, mainly regarding lipid, glucose, arterial hypertension alterations and cardiovascular risk (CVR). The objective of metabolic monitoring is A1C ≤7%, similar to that of non-infected population, individualising by age, life expectancy, comorbidities, hypoglycaemia risk and costs...

INTRODUCTION: Recurrence is one of the main reasons for poor prognosis of OSCC. The mortality rate is approximately 90% and the 5-year overall survival rate decreases from 90% to 30% when recurrence is diagnosed. Identification of clinicopathological risk factors predicting recurrence may be helpful for patient individualized management and improvement of therapy. Therefore we investigated in our study the incidence of locoregional recurrences and their association with clinicopathological factors to identify possible significant risk factors...

Feasibility of cerebral tissue oxygenation measurements immediately after birth has been published starting with first values 2 min after birth. Aim of this study was to evaluate, the time periods from birth and from arrival at the resuscitation table to obtain the first cerebral tissue oxygenation values with two different near infrared spectroscopy (NIRS) devices. The present study is an analysis of exploratory parameters of two prospective observational studies. Cerebral tissue oxygen saturation was measured by the NIRO 200NX measuring "cerebral-tissue-oxygenation-index" (cTOI) or the INVOS5100C measuring "cerebral-regional-oxygen-saturation" (crSO2)...

INTRODUCTION: Recent avoidable failures in patient care highlight the ongoing need for evidence to support improvements in patient safety. According to the most recent reviews, there is a dearth of economic evidence related to patient safety. These reviews characterise an evidence gap in terms of the scope and quality of evidence available to support resource allocation decisions. This protocol is designed to update and improve on the reviews previously conducted to determine the extent of methodological progress in economic analyses in patient safety...

INTRODUCTION: Cardiovascular disease (CVD) is a leading cause of morbidity and mortality worldwide. Psychological risk factors such as stress, anxiety and depression are known to play a significant and independent role in the development and progression of CVD and its risk factors. Tai Chi has been reported to be potentially effective for health and well-being. It is of value to assess the effectiveness and safety of Tai Chi on psychological well-being and quality of life in people with CVD and/or cardiovascular risk factors...

INTRODUCTION: Studies on outcomes and risk factors for neonatal nephrocalcinosis (NC) and renal calculi (RC) are limited, and often do not include controls for comparison. We conducted a case-control analysis to identify risk factors associated with NC and/or RC in neonates and studied the natural course of these anomalies. STUDY DESIGN: Infants diagnosed with NC/RC on ultrasound within the first year of life and corresponding gestational age- and gender-matched controls were identified from the neonatal intensive care unit database at our institution over a 10-year period...

Cannabidiol has recently been proposed as an antipsychotic for schizophrenia. However, its clinical use and safety is controversial. To answer this question, we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We identified six systematic reviews incorporating four primary studies overall, including two randomized trials. We extracted data from the systematic reviews, reanalyzed data from primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach...

BACKGROUND: Persistent (chronic) pain is a frequent complaint in survivors of torture, particularly but not exclusively pain in the musculoskeletal system. Torture survivors may have no access to health care; where they do, they may not be recognised when they present, and the care available often falls short of their needs. There is a tendency in state and non-governmental organisations' services to focus on mental health, with poor understanding of persistent pain, while survivors may have many other legal, welfare, and social problems that take precedence over health care...

The predator mite Iphiseiodes zuluagai Denmark & Muma is an important biological-control agent of mite pests, and it is one of the most common species found in citrus orchards. This study assessed, under laboratory conditions, the toxicity and duration of the harmful effects of five insecticides, the three pyrethroids deltamethrin, esfenvalerate and lambda-cyhalothrin, and the two neonicotinoids imidacloprid and thiamethoxam on I. zuluagai. Furthermore, we estimated the life-table parameters of the predator...

Marine debris is widely recognized as a global environmental problem. One of its main components, microplastics, has been found in several sea salt samples from different countries, indicating that sea products are irremediably contaminated by microplastics. Previous studies show very confusing results, reporting amounts of microparticles (MPs) in salt ranging from zero to 680 MPs/kg, with no mention of the possible causes of such differences. Several errors in the experimental procedures used were found and are reported in the present work...

Life expectancy (LE) based on a period life table (PLT) traditionally serves as a general population summary metric. It is, however, becoming more frequently reported for chronically afflicted subpopulations. In general populations, there is always an obvious real cohort sharing the hypothetical PLT cohort characteristics, and the LE estimate is intuitively understood as that real cohort mean survival time, assuming constancy of death risks. In diseased subpopulations, the correspondence between the hypothetical cohort and a real cohort is not straightforward...
