The development of predictive, sensitive and reliable biomarkers is of crucial importance for aquatic biomonitoring to assess the effects of chemical substances on aquatic organisms, especially when it comes to combined effects with other stressors (e.g. temperature). The first purpose of the present study was to evaluate the single and combined effects of 90 days of exposure to an environmental cadmium concentration (0.5 μg L-1 ) and two water temperatures (16 and 21 °C) on different parameters. These parameters are involved in (i) the antioxidant system (superoxide dismutase activity -SOD- and total glutathione levels -GSH-), (ii) the energy metabolism, i...

We studied disparity-evoked responses in natural scenes using high-density electroencephalography (EEG) in an event-related design. Thirty natural scenes that mainly included outdoor settings with trees and buildings were used. Twenty-four subjects viewed a series of trials composed of sequential two-alternative temporal forced-choice presentation of two different versions (two-dimensional [2D] vs. three-dimensional [3D]) of the same scene interleaved by a scrambled image with the same power spectrum. Scenes were viewed orthostereoscopically at 3 m through a pair of shutter glasses...

BACKGROUND: Birth asphyxia is a leading cause of early neonatal death. In 2013, 32% of neonatal deaths in Zambia were attributable to birth asphyxia and trauma. Basic, timely interventions are key to improving outcomes. However, data from the World Health Organization suggest that resuscitation is often not initiated, or is conducted suboptimally. Currently, there are little data on the quality of newborn resuscitation in the context of a tertiary center in a lower-middle income country...

In September 2016, Médecins Sans Frontières responded to a hepatitis E (HEV) outbreak in Chad by implementing water treatment and hygiene interventions. To evaluate the coverage and use of these interventions, we conducted a cross-sectional study in the community. Our results showed that 99% of households interviewed had received a hygiene kit from us, aimed at improving water handling practice and personal hygiene and almost all respondents had heard messages about preventing jaundice and handwashing. Acceptance of chlorination of drinking water was also very high, although at the time of interview, we were only able to measure a safe free residual chlorine level (free chlorine residual (FRC) ≥0...

In this work, a novel mesoporous luminescence-functionalized metal-organic framework (Ru-PCN-777) with high stability and excellent electrochemiluminescence (ECL) performance was synthesized by immobilizing Ru(bpy)2(mcpbpy)2+ on the Zr6 cluster of PCN-777 via a strong coordination bond between Zr4+ and -COO-. Consequently, the Ru(bpy)2(mcpbpy)2+ could not only cover the surface of PCN-777, but also grafted into the interior of PCN-777, which greatly increased the loading amount of Ru(bpy)2(mcpbpy)2+ and effectively prevented the leaching of the Ru(bpy)2(mcpbpy)2+ resulting in a stable and high ECL response...

OBJECTIVE: Individuals vary in how they respond to bereavement. Those who experience poor bereavement outcomes often report symptoms from more than one diagnostic category. This study sought to identify groups of individuals who share similar patterns of prolonged grief disorder and posttraumatic stress disorder symptoms to determine whether these profiles are differentially related to negative appraisals thought to contribute to prolonged grief disorder and posttraumatic stress disorder symptomatology...

PURPOSE: Severe asthma and asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) are difficult to control and are often associated with poor clinical outcomes. However, much is not understood regarding the diagnosis and treatment of severe asthma and ACOS. To evaluate the current perceptions of severe asthma and COPD among asthma and COPD specialists, we designed an e-mail and internet-based questionnaire survey. METHODS: Subjects were selected based on clinical specialty from among the members of the Korean Academy of Asthma, Allergy and Clinical Immunology and the Korean Academy of Tuberculosis and Respiratory Diseases...

INTRODUCTION: The outcomes of failed laparoscopic sleeve gastrectomies (LSG) converted to laparoscopic standard R-Y gastric bypass (LRYGB) in case of insufficient weight loss (IWL), weight regain (WR), and/or severe gastro-esophageal reflux disease (GERD) are scanty. PURPOSE: To evaluate incidence, indications, and short-term outcomes of LSG conversion to LRYGB in three bariatric centers. METHODS: Patients operated between January 2012 and December 2016 by primary LSG, with mean follow-up of 24 months and converted to LRYGB for IWL, WR, and/or GERD, were retrospectively analyzed for demographics, operative details, perioperative complications, comorbidities evolution, and further WL...

Background: The use of embryo cryopreservation excludes the possible detrimental effects of ovarian stimulation on the endometrium, and higher reproductive outcomes following this policy have been reported. Moreover, gonadotropin-releasing hormone agonist trigger in gonadotropin-releasing hormone (GnRH) antagonist cycles as a substitute for standard human chorionic gonadotropin trigger, minimizes the risk of ovarian hyperstimulation syndrome (OHSS) in fresh as well as frozen embryo transfer cycles (FET)...

Patients with high-grade serous ovarian carcinoma (HGSC) exhibit poor 5-year survival rates, which may be significantly improved by early-stage detection. The U.S. Food and Drug Administration-approved biomarkers for HGSC-CA-125 (cancer antigen 125) and HE4 (human epididymis protein 4)-do not generally appear at detectable levels in the serum until advanced stages of the disease. An implantable device placed proximal to disease sites, such as in or near the fallopian tube, ovary, uterine cavity, or peritoneal cavity, may constitute a feasible strategy to improve detection of HGSC...

The change from traditional to a more mechanized and technical agriculture has involved, in many cases, land transformations. This has supposed alteration of landforms and soils, with significant consequences. The effects of induced soil variability and the subsequent implications in site-specific crop management have not been sufficiently studied. The present work investigated the application of a resistivity soil sensor (Veris 3100), to map the apparent electrical conductivity (ECa), and detailed multispectral airborne images to analyse soil and crop spatial variability to assist in site-specific orchard management...

Understanding factors associated with youth e-cigarette openness and curiosity are important for assessing probability of future use. We examined how e-cigarette harm perceptions and advertising exposure are associated with openness and curiosity among tobacco naive youth. Findings from the 2015 National Youth Tobacco Survey (NYTS) were analyzed. The 2015 NYTS is a nationally representative survey of 17,711 U.S. middle and high school students. We calculated weighted prevalence estimates of never users of tobacco products (cigarettes, cigars/cigarillos/little cigars, waterpipe/hookah, smokeless tobacco, bidis, pipes, dissolvables, e-cigarettes) who were open to or curious about e-cigarette use, by demographics...

Fungal otitis (otomycosis) is a common infection encountered by otolaryngologists. Nevertheless, its management can be challenging because of its high recurrence rate and of the limited therapeutic options. A 45-year-old woman suffered from recurrent otomycosis. The ineffectiveness of successive antibiotic cures and repeated topical treatments with nystatin and then with econazole cream led to perform microbiological analyses. Culture of ear swab grew Aspergillus niger. The use of a 1% voriconazole sterile solution previously validated for treatment of eye infections was considered after ensuring the absence of known ototoxic effects of the antifungal and of the excipients...

OBJECTIVE: A high dose of prolonged gonadotropins can yield higher numbers of oocytes and embryos. The high dose or prolonged regimens can be associated with ovarian hyperstimulation syndrome (OHSS), multiple gestations, emotional stress, economical burden and treatment dropout. In mild stimulation lower doses and shorter duration times of gonadotropin are used in contrast to the conventional long stimulation protocol in IVF. It has been proposed that supraphysiologic levels of hormones may adversely affect endometrium and oocyte/embryo...

This narrative review highlights key issues in men's mental health and identifies approaches to research, policy and practice that respond to men's styles of coping. Issues discussed are: 1) the high incidence of male suicide (80% of suicide deaths in Canada, with a peak in the mid-50 s age group) accompanied by low public awareness; 2) the perplexing nature of male depression, manifesting in forms that are poorly recognised by current diagnostic approaches and thus poorly treated; 3) the risky use of alcohol among men, again common and taking a huge toll on mental and physical health; 4) the characteristic ways in which men manage psychological suffering, the coping strengths to be recognised, and the gaps to be addressed; 5) the underutilization of mental health services by men, and the implication for clinical outcomes; and 6) male-specific approaches to service provision designed to improve men's accessing of care, with an emphasis on Canadian programs...

The prefabricated cement-based partition wall has been widely used in assembled buildings because of its high manufacturing efficiency, high-quality surface, and simple and convenient construction process. In this paper, a general porous partition wall that is made from cement-based materials was proposed to meet the optimal mechanical and thermal performance during transportation, construction and its service life. The porosity of the proposed partition wall is formed by elliptic-cylinder-type cavities. The finite element method was used to investigate the mechanical and thermal behaviour, which shows that the proposed model has distinct advantages over the current partition wall that is used in the building industry...

AIM: To develop and psychometrically assess the Ethical Awareness Scale using Rasch measurement principles and a Rasch item response theory model. BACKGROUND: Critical care nurses must be equipped to provide good (ethical) patient care. This requires ethical awareness, which involves recognizing the ethical implications of all nursing actions. Ethical awareness is imperative in successfully addressing patient needs. Evidence suggests that the ethical import of everyday issues may often go unnoticed by nurses in practice...
