BACKGROUND: Posttraumatic stress disorder (PTSD) is a complex psychiatric illness that can be difficult to diagnose, due in part to its comorbidity with major depressive disorder (MDD). Given that researchers have found no difference in prevalence rates of PTSD and MDD after accounting for overlapping symptoms, the latent structures of PTSD and MDD may account for the high comorbidity. In particular, the PTSD Negative Alterations in Cognition and Mood (NACM) and Hyperarousal factors have been characterized as non-specific to PTSD...

PURPOSE: This study aims to describe Muller's muscle-conjunctival resection surgery in terms of outcomes and potential factors that may predict final positions. METHODS: This cross-sectional cohort study included patients undergoing Muller's muscle-conjunctival resection surgery for involutional ptosis over a 15-year period. Success was defined in 2 ways: 1) final marginal reflex distance 1 (MRD1) ≥2.5 mm (MRD1 success) and 2) final difference in MRD1 ≤1 mm between eyelids (symmetry success)...

BACKGROUND: Thin basement membrane nephropathy (TBMN) is the most common cause of persistent glomerular hematuria. Most individuals with TBMN show a benign course, although it can be difficult to distinguish it from early stages of progressive renal diseases. However, only limited studies address the prognosis of donors with TBMN and their recipients. METHODS: From 2007 to 2016, 11 recipients received kidney grafts from donors with TBMN, and their clinical data were analyzed retrospectively...

Endoscopic mucosal resection and endoscopic submucosal dissection (ESD) are operative endoscopies that have been performed since a long time. Recently, an evolution of laparoscopy called transanal minimally invasive surgery began to be popularized, and it can be adopted in the face of difficult cases for endoscopic mucosal resection/ESD. In this video, a 36-year-old woman was submitted to transanal minimally invasive surgery resection, after unsuccessful ESD, for a 2-cm polyp located anteriorly in the anal canal, just beyond the pectineal line...

Accurately modelling the structure of a catalyst is a fundamental prerequisite for correctly predicting reaction pathways, but a lack of clear experimental benchmarks makes it difficult to determine the optimal theoretical approach. Here, we utilize the normal incidence X-ray standing wave (NIXSW) technique to precisely determine the three dimensional geometry of Ag1 and Cu1 adatoms on Fe3O4(001). Both adatoms occupy bulk-continuation cation sites, but with a markedly different height above the surface (0.43 ± 0...

Ovarian fibromas are the most common benign solid ovarian tumors, which are often difficult to diagnose preoperatively. Ovarian fibromas, especially in bilateral cases, may be cases of Gorlin-Goltz syndrome (GGS), a rare autosomal dominant disorder with predisposition to basal cell carcinomas (BCCs) and other various benign and malignant tumors. This case report describes a 25 year-old female with GGS, bilateral ovarian fibroma, endometriosis and septated uterus, which was referred to the Gynecology Clinic of Rasoul-e-Akram Hospital in October 2016...

Pollutants in wastewater include oils, dyes, and bacteria, making wastewater cleanup difficult. Here, we propose the preparation of multifunctional wastewater treatment media, poly(ionic liquid) grafted polypropylene (PP) nonwoven fabrics (PP@PIL), prepared via a simple and scalable surface grafting process. The fabricated PP@PIL fabrics exhibited superior switchable oil/water separation (η > 99%) and dye absorption performance (q = 410 mg/g), as well as high antibacterial properties. The oil/water separation could be easily switched via anion-exchanging of PIL segments...

Witold X Chmielewski, Moritz Mückschel, Christian Beste
The inhibition of prepotent responses is a requirement for goal-directed behavior and several factors determine corresponding successful response inhibition processes. One factor relates to the degree of automaticity of pre-potent response tendencies and another factor relates to the degree of cognitive control that is exerted during response inhibition. However, both factors can conjointly modulate inhibitory control. Cognitive theoretical concepts suggest that codings of stimulus-response translations may underlie such conjoint effects...

Colonic diverticular bleeding is the most common cause of lower gastrointestinal bleeding1,2 . Appendiceal diverticulosis is an uncommon clinical entity, with an incidence of 0.004%-2% in surgical pathologic specimens3,4 . Appendiceal diverticulitis in symptomatic patients should be treated with early resection, because of the risk of perforation and peritonitis; the rate of perforation is higher in appendicitis (27%) with diverticulosis than in appendicitis alone (6.6%)5 . Untreated appendiceal diverticulitis can also lead to massive gastrointestinal hemorrhage and abscess formation, and has a potential role in the development of pseudomyxoma peritonei...

STRUCTURED ABSTRACT Background: On May 14, 2013, the National Transportation Safety Board ("NTSB") proposed that states lower the blood alcohol concentration ("BAC") illegal limit from .08 g/dL to .05 g/dL (also referred to as the ".08 law" and "the .05 limit," respectively). In March of 2017, this recommendation was signed into law in the State of Utah. OBJECTIVE: The objective of this survey is to investigate perceptions regarding enforcement of the .05 g/dL BAC limit. METHOD: Opinions of law enforcement officers, prosecutors, and defense attorneys were obtained through a series of questionnaires and focus groups...

Lipoblastoma is part of tumors derived from adipose tissue. It is a benign neoplasm that can be localized or diffuse, affecting children in early childhood and usually located in the trunk and extremities. These tumors are uncommon in the pediatric age, but when one of them is present, it is a challenge that we must resolve quickly due to the risk of malignancy that involves other similar neoplastic lesions. The preoperative diagnosis is difficult, because the imaging methods do not provide specific information that allows us to differentiate them from other tumors, such as liposarcomas...

Macrosomia is a risk factor for birth injuries and is associated with neonatal morbidity and mortality. Cephalohematoma and clavicular fracture are the most frequent birth injuries. Intraabdominal injuries are uncommon birth injuries. Rectus sheath hematoma (RSH) is an accumulation of blood in the sheath of rectus abdominis muscle. It is associated with trauma, operations and anticoagulant therapy, especially in adults and elders. We present a macrosomic male neonate with difficult vaginal delivery, who had in the physical examination periumblical ecchymose of 1x1 cm and a parietal cephalohametoma of 1x1 cm...

INTRODUCTION: Myelomeningocele is a congenital defect that occurs when the neural tube fails to close completely. It causes body composition alterations and a high prevalence of obesity. It is difficult to detect the most adequate indicator for a nutritional diagnosis due to the impossibility of recording accurate anthropometric measurements. OBJECTIVE: To describe body composition, resting energy expenditure and metabolic disorders in a population of patients with myelomeningocele managed at "Hospital Garrahan" by comparing obese patients with myelomeningocele and a control population with multifactorial obesity...

BACKGROUND: Ureaplasma species (Usp) are the most prevalent genital Mycoplasma isolated from the urogenital tract of both men and women. Usp may be commensals in the genital tract but may also be contributors to a number of pathological conditions of the genital tract. Because they can also just colonize the genital tract of healthy people, their pathogenic role can be difficult to prove. OBJECTIVES: The aim of the study was to evaluate the efficacy of a quantitative polymerase chain reaction (qPCR) method for the discrimination between infection and colonization by measuring prevalence of Usp in asymptomatic versus symptomatic patients...

Ecological communities typically change along gradients of human impact, though it is difficult to estimate the footprint of impacts for diffuse threats like pollution. Here we develop a joint model of benthic habitats on lagoonal coral reefs and use it to infer change in benthic composition along a gradient of distance from logging operations. The model estimates both changes in abundances of benthic groups and their compositional turn-over, a type of beta-diversity. We detect compositional turnover across the gradient and use the model to predict the footprint of turbidity impacts from logging...

The Gleason scoring system is a key component of a prostate cancer diagnosis, since it indicates disease aggressiveness. It also serves as a risk communication tool that facilitates shared treatment decision-making. However, the system is highly complex and therefore difficult to communicate: factors which have been shown to undermine well-informed and high-quality shared treatment decision-making. To systematically explore prostate cancer patients' understanding of the Gleason scoring system (GSS), we assessed knowledge and perceived importance among men who had completed treatment (N = 50)...

Background: Administration of intradermal fractional dose of inactivated poliovirus vaccine (fIPV) has proven to be safe and immunogenic; however, its intradermal application using needle and syringe is technically difficult and requires trained personnel. Methods: We assessed feasibility of conducting an intradermal fIPV campaign in polio high risk neighborhood of Karachi using Tropis needle-free injector. During the one-day fIPV campaign, we measured average "application time" to administer fIPV with Tropis, collected ergonomic information and measured vaccine wastage...

Urine tests are performed by using an off-the-shelf reference sheet to compare the color of test strips. However, the tabular representation is difficult to use and more prone to visual errors, especially when the reference color-swatches to be compared are spatially apart. Thus, making it is difficult to distinguish between the subtle differences of shades on the reagent pads. This manuscript represents a new arrangement of reference arrays for urine test strips (urinalysis). Reference color swatches are grouped in a doughnut chart, surrounding each reagent pad on the strip...
