OBJECTIVE: To determine the prevalence of soft tissue calcifications in cone beam computed tomography (CBCT) scans with different fields of view (FOV), and to assess its relation with the clinical relevance of the CBCT findings. MATERIAL AND METHODS: One thousand CBCT scans were grouped according to FOV's size and region scanned (MX-FOV, maxilla; MD-FOV, mandible; and MM-FOV, maxilla/mandible) and evaluated for the presence of soft tissue calcifications. Laterality and length of the elongated styloid processes (ESP) were also assessed...

Epigenetic regulation plays a critical role in gene expression, cellular differentiation, and disease. There is a complex interplay between the different layers of epigenetic information, including DNA methylation, nucleosome positions, histone modifications, histone variants, and other important epigenetic regulators. The different modifications do not act independently of each other and their relationship plays an important role in governing the regulation of the epigenome. Of these, DNA methylation is the best-studied epigenetic modification in mammals...

Aberrations of the DNA methylome contribute to onset and progression of diseases. Whole genome bisulfite sequencing (WGBS) is the only analytical method covering the complete methylome. Alternative methods requiring less DNA than WGBS analyze only a minor portion of the methylome and do not cover important regulatory features like enhancers and noncoding RNAs. In tagmentation-based WGBS (TWGBS), several DNA and time-consuming steps of the conventional WGBS library preparation are circumvented by the use of a hyperactive transposase, which simultaneously fragments DNA and appends sequencing adapters...

PURPOSE: Ferritin is an intracellular iron storage protein and a marker of inflammation. Studies have shown that subjects with obstructive sleep apnea (OSA) have higher levels of circulating pro-inflammatory cytokines, but little is known about the association between ferritin and OSA. The aims of the study were to evaluate serum ferritin (S-Ferritin) levels in OSA patients compared to levels in the general population and also examine the effect of obesity level and treatment with positive airway pressure (PAP) on S-Ferritin levels...

Before menopause, women are protected from atherosclerotic heart disease associated with obesity relative to men. Sex hormones have been proposed as a mechanism that differentiates this risk. In this review, we discuss the literature around how the endogenous sex hormones and hormone treatment approaches after menopause regulate fatty acid, triglyceride, and cholesterol metabolism to influence cardiovascular risk.The important regulatory functions of estrogen signaling pathways with regard to lipid metabolism have been in part obscured by clinical trials with hormone treatment of women after menopause, due to different formulations, routes of delivery, and pairings with progestins...

OBJECTIVE: This article explores the impact of regulations on the implementation of collective protections in France to occupational exposure to carcinogenic, mutagenic and reprotoxic (CMR) agents. METHODS: Individual data from the French national cross-sectional survey of occupational hazards conducted in 2010 were analysed. We investigated whether stricter regulations and longer exposures were associated with higher level of collective protection using multivariate logistic regressions...

There have been several recent publications related to therapeutic obstinacy and futility in the Intensive Care Unit. However, little has been published about "the family obstinacy" in persisting with invasive measures in seriously ill patients, despite the appropriate information provided to them about the patient's poor short-term prognosis. On certain occasions, these critical patients are unable to make decisions on the proposed treatments and, unfortunately, many of them have not previously indicated their preferences in terms of limits to invasive measures (advanced directives)...

In a climate change scenario, it is important to understand the factors that lead to changes in a soil carbon (C) sink. It is recognized that such process is highly dependent on climate, soil properties, topography, and vegetation. However, few studies demonstrate how these mechanisms operate in highly weathered Oxisols. Therefore, this study evaluated the driving factors for C recovery and accumulation and its relations with fertility attributes in the soil profile (0 to 1m depth) in no-till (NT) croplands of south Brazil...

Toads are among several groups of organisms chemically defended with lethal concentrations of cardiotonic steroids. As a result, most predators that prey on amphibians avoid toads. However, several species of snakes have gained resistance-conferring mutations of Na+/K+-ATPase, the molecular target of cardiotonic steroids, and can feed on toads readily. Despite recent advances in our understanding of this adaptation at the genetic level, we have lacked functional evidence for how mutations of Na+/K+-ATPase account for cardiotonic steroid resistance in snake tissues...

BACKGROUND: Improved imaging methods are critical to assess neurodegeneration and remyelination in multiple sclerosis. Chronic hypointensities observed on T1-weighted brain MRI, "persistent black holes," reflect severe focal tissue damage. Present measures consist of determining persistent black holes numbers and volumes, but do not quantitate severity of individual lesions. OBJECTIVE: Develop a method to differentiate black and gray holes and estimate the severity of individual multiple sclerosis lesions using standard magnetic resonance imaging...

BACKGROUND: Anaerobic threshold (AT) is recognized as objective and direct measurement that reflects variations in metabolism of skeletal muscles during exercise. Its prognostic value in heart diseases of non-chagasic etiology is well established. However, the assessment of risk of death in Chagas heart disease is relatively well established by Rassi score. But, the added value that AT can bring to Rassi score has not been studied yet. OBJECTIVES: To assess whether AT presents additional effect to Rassi score in patients with chronic Chagas' heart disease...

Fear generalization occurs when a response, previously acquired with a threatening stimulus, is transferred to a similar one. However, it could be maladaptive when stimuli that do not represent a real threat are appraised as dangerous, which is a hallmark of several anxiety disorders. Stress exposure is a major risk factor for the occurrence of anxiety disorders and it is well established that it influences different phases of fear memory; nevertheless, its impact on the generalization of contextual fear memories has been less studied...

Women show better performance than men on a range of episodic memory tasks. Evidence regarding a neuroanatomical localization of this effect remains ambiguous. It has been suggested that anterior temporal lobe structures are responsible for sex differences in verbal memory, yet temporal lobe epilepsy (TLE) and TLE surgery do not affect women's verbal memory advantage. Instead, frontal lobe regions may be relevant for female verbal memory superiority, i.e. by enabling more efficient encoding and retrieval strategies in women...

REVIEW
Saskia Haegens, Elana Zion Golumbic
Here we review the role of brain oscillations in sensory processing. We examine the idea that neural entrainment of intrinsic oscillations underlies the processing of rhythmic stimuli in the context of simple isochronous rhythms as well as in music and speech. This has been a topic of growing interest over recent years; however, many issues remain highly controversial: how do fluctuations of intrinsic neural oscillations-both spontaneous and entrained to external stimuli-affect perception, and does this occur automatically or can it be actively controlled by top-down factors? Some of the controversy in the literature stems from confounding use of terminology...

INTRODUCTION: Pediatric surgeons, anesthesia providers, and nurses from North America and other high-income countries (HICs) are increasingly engaged in resource-limited areas, with short-term missions (STMs) as the most common form of involvement. However, consensus recommendations currently do not exist for STMs in pediatric general surgery and associated perioperative care. METHODS: The American Academy of Pediatrics (AAP) Delivery of Surgical Care Subcommittee and American Pediatric Surgical Association (APSA) Global Pediatric Surgery Committee, with the American Pediatric Surgical Nurses Association, Inc...

PURPOSE: Artificial tears are widely used in the treatment of dry eye disease, although current formulations do not closely resemble natural tears. The purpose of this study was the design and characterization of a novel in situ gelling artificial tear formulation, containing both lipid and aqueous components, in order to resemble natural tears and replenish the tear film. METHODS: Liposomes, containing phosphatidylcholine, cholesterol, vitamins A and E, were prepared by the thin-film hydration method...

BACKGROUND: Infant socioemotional development is often held under informal surveillance, but a formal screening program is needed to ensure systematic identification of developmental risk. Even when screening programs exist, they are often ineffective because health care professionals do not adhere to screening guidelines, resulting in low screening prevalence rates. OBJECTIVES: To examine feasibility and acceptability of implementing universal screening for infant socioemotional problems with the Alarm Distress Baby Scale in primary care...

BACKGROUND: In clinical trials, statistical analysis often requires certain assumptions about missing data for a valid statistical inference. If the dropout rate is high, a wrong assumption about the missing data may compromise the validity of statistical inferences. PURPOSE: To mitigate the high dropout rates commonly observed in psychiatry clinical trials, we consider two design approaches for short-term controlled trials submitted in support of marketing applications for drug products for the major depressive disorder (MDD) indication: (1) shortening the trial duration and (2) treating time to treatment discontinuation as an alternative primary efficacy endpoint...

BACKGROUND: The psychiatric ward is a place where all forms of violence are treated. Occasionally, this violence involves acts of aggression between patients in emergency psychiatric units or hospital wards. Such events can lead to the development or worsening of posttraumatic stress disorder. METHODS: To establish the context, we first examined the epidemiology data concerning posttraumatic stress disorder in psychiatric patients who were frequently exposed to assaults...
