Juan-Ying Li, Wenxuan Shi, Zhenhua Li, Yiqin Chen, Liu Shao, Ling Jin
Mariculture product safety in relation to sediment quality has attracted increasing attention because of the accumulation of potentially hazardous chemicals, including pyrethroid insecticides, in sediment. Passive sampling has been widely used to assess the bioavailability of sediment-associated hydrophobic organic contaminants and predict their body residue in benthic organisms. Therefore, in this study, we introduced polydimethylsiloxane (PDMS) polymer as a biomimetic "chemometer" for freely-dissolved concentrations (Cfree) to assess the efficacy of different carbon sorbents in reducing the bioavailability of pyrethroids in the process of sediment remediation...

Cortical activity changes continuously during the course of the day. At a global scale, population activity varies between the 'synchronized' state during sleep and 'desynchronized' state during waking. However, whether local fluctuations in population synchrony during wakefulness modulate the accuracy of sensory encoding and behavioral performance is poorly understood. Here, we show that populations of cells in monkey visual cortex exhibit rapid fluctuations in synchrony ranging from desynchronized responses, indicative of high alertness, to highly synchronized responses...

Somer Harvey, A Brad Hall, Kayla Wilson
BACKGROUND: Targeted antibiotic treatment reduces the infection risk of open fractures when soft tissue and bone are exposed to the environment. The risk of infection increases with higher degrees of injury. The Gustilo-Anderson system was developed to identify the degree of injury of open fractures and can be utilized to guide initial antibiotic therapy. Few studies have been published evaluating the potential impact of emergency medicine pharmacists in trauma, and currently no study has evaluated a pharmacist's influence on antibiotic selection and timing for open fractures...

AIM AND OBJECTIVE: The aim of this study was to explore the association between oral health and nutritional status in the context of daily care for older people. BACKGROUND: Oral problems often increase with age and affect a person's ability to chew and swallow. They might also influence the ability to maintain a satisfactory nutritional status. Oral health awareness is therefore of great importance in nursing care for older people. METHODS: Data from the Swedish quality register, Senior Alert, were used, including structured assessments of both oral and nutritional status using the Revised Oral Assessment Guide - Jönköping (ROAG-J) and the Mini Nutritional Assessment (MNA)...

The photochemical fate of the herbicide clethodim in natural waters was investigated under simulated and natural sunlight radiation. This herbicide exhibited a rapid degradation rate in simulated aquatic environment with half-lives ranged from 27.9min to 4.6h. The commercial formulation of clethodim showed a faster degradation with half-lives from 19.3min to 1.4h. It has also been demonstrated that the photolytic behavior of clethodim was affected by the water composition and the radiation intensity. Nine major photoproducts were identified and their distribution was dependent on the experimental conditions...

CONTEXT: in Belgium 70 % of the children aged 0 - 14 years have at least one annual contact with their family doctor, while for the same period, only 6 - 12 % of them will see a neuropaediatrician and/or a child psychiatrist, despite the fact that a diagnostic of Externalizing behavior before the age of 6 to 7 years, such as various ways of aggressiveness, of anger or of stealing will very often alert the family, the staff of creches or nursery as well as the teachers. Other children are showing signs of Internalizing behavior, very often together with depression or other forms of anxiety...

Backgound Partographs are used in many labour settings to provide a pictorial overview of a woman's cervical dilation pattern in the first stage of labor and to alert clinicians to slow progress possibly requiring intervention. Recent reviews called for large trials to establish the efficacy of partographs to improve birth outcomes whilst highlighting issues of clinician compliance with use. Previous studies have also reported issues with participant recruitment related to concerns regarding the possibility of a longer labour...

BACKGROUND AND PURPOSE: Clinical outcomes in patients with acute ischemic stroke caused by large vessel occlusion depend on the speed and quality of workflows leading to mechanical thrombectomy. In the absence of universally accepted best practices for workflow, developing stroke hospitals can benefit from improved awareness of real-world workflows in effect at experienced centers. To this end, we surveyed prethrombectomy workflow practices at stroke centers throughout the United States...

During radiation therapy of head and neck cancer, the decision to consider replanning a treatment because of anatomical changes has significant resource implications. We developed an algorithm that compares cone-beam computed tomography (CBCT) image pairs and provides an automatic alert as to when remedial action may be required. Retrospective CBCT data from ten head and neck cancer patients that were replanned during their treatment was used to train the algorithm on when to recommend a repeat CT simulation (re-CT)...

OBJECTIVES: Rapid epidemic detection is an important objective of surveillance to enable timely intervention, but traditional validated surveillance data may not be available in the required timeframe for acute epidemic control. Increasing volumes of data on the Internet have prompted interest in methods that could use unstructured sources to enhance traditional disease surveillance and gain rapid epidemic intelligence. We aimed to summarise Internet-based methods that use freely-accessible, unstructured data for epidemic surveillance and explore their timeliness and accuracy outcomes...

The superior colliculus (SC) receives direct input from the retina and integrates it with information about sound, touch, and state of the animal that is relayed from other parts of the brain to initiate specific behavioral outcomes. The superficial SC layers (sSC) contain cells that respond to visual stimuli, whereas the deep SC layers (dSC) contain cells that also respond to auditory and somatosensory stimuli. Here, we used a large-scale silicon probe recording system to examine the visual response properties of SC cells of head-fixed and alert male mice...

State Medicaid programs need cost-effective strategies to provide high-quality care that is accessible to individuals with low incomes and limited resources. Integrated delivery systems have been formed to provide care across the continuum, but creating a shared vision for improving community health can be challenging. Medical Home Network was created as a network of primary care providers and hospital systems providing care to Medicaid enrollees, guided by the principles of egalitarian governance, practice-level care coordination, real-time electronic alerts, and pay-for-performance incentives...

Much of the scientific work addressing the enigmas of anxiety and its disorders has been conducted among European Americans. This work has led to great progress into the nature of anxiety psychopathology, including etiologic, maintenance, and relapse processes. Moreover, evidenced-based treatments for anxiety and its disorders have arguably been among the best in the field of psychopathology for well over two decades. Yet, the progress thus far attained on the nature and treatment of anxiety disorders has not benefited all members of society equally...
