Sewage treatment plants (STPs) are one of the sources of pathogens discharged into surface water. An investigation was carried out over the duration of 12 months in Henan Province, China, to evaluate the health influence of municipal wastewater effluent discharge on water quality of the receiving water. A discharge-based quantitative microbial risk assessment (QMRA) was employed, taking into account the vegetables consumption habits of the Chinese, population subgroups with different immune statuses and ages, to evaluate the incremental disease burden from agricultural irrigation and swimming exposure scenarios associated with increased concentration of the protozoan Cryptosporidium and/or Giardia in the receiving river...

Medical abortion is a safe, effective, and acceptable option for patients seeking an early non-surgical abortion. In 2014, medical abortion accounted for nearly one-third (31%) of all abortions performed in the United States. State-level attempts to restrict reproductive and sexual health have recently included bills that require physicians to inform women that a medical abortion is reversible. In this commentary, we will review the history, current evidence-based regimen, and regulation of medical abortion...

Thao Tran, Brian Cannon
Internal loops within structured nucleic acids disrupt local base-stacking and destabilize neighboring helical domains; however, these structural motifs also expand the conformational and functional capabilities for structured nucleic acids. Variations in size, distribution of loop nucleotides on opposing strands (strand asymmetry), and sequence alter their biophysical properties. Here, the thermodynamics and structural flexibility of poly(T)-rich DNA internal loops were systematically investigated in terms of loop size and strand asymmetry...

The brain can only attend to a fraction of all the information that is entering the visual system at any given moment. One way of overcoming the so-called bottleneck of selective attention (e.g., J. M. Wolfe, Võ, Evans, & Greene, 2011) is to make use of redundant visual information and extract summarized statistical information of the whole visual scene. Such ensemble representation occurs for low-level features of textures or simple objects, but it has also been reported for complex high-level properties...

Importance: Advances in smartphone photography (both quality and image transmission) may improve access to care via direct parent-to-clinician telemedicine. However, the accuracy of diagnoses that are reliant on parent-provided photographs has not been formally compared with diagnoses made in person. Objective: To assess whether smartphone photographs of pediatric skin conditions taken by parents are of sufficient quality to permit accurate diagnosis. Design, Setting, and Participants: A prospective study was conducted among 40 patient-parent dyads at a pediatric dermatology clinic at the Children's Hospital of Philadelphia from March 1 to September 30, 2016, to assess concordance between diagnoses made by an independent pediatric dermatologist based on in-person examination and those based on parental photographs...

<p>Both pulsed dye laser (PDL) and intense pulsed light (IPL) systems have been demonstrated to be effective for treatment of facial telangiectasia, however there have been very few comparative studies between both treatments involving purely Asian patient populations. In this study, we performed a retrospective analysis to compare the efficacy of PDL and IPL systems for the treatment of facial telangiectasia. A total of 416 patients with facial telangiectasia who were treated by PDL or IPLs in our department from August 2012 to March 2015 were included in this study...

MultiCellular Tumor Spheroids (MCTS), which mimic the 3-Dimensional (3D) organization of a tumor, are considered as better models than conventional cultures in 2-Dimensions (2D) to study cancer cell biology and to evaluate the response to chemotherapeutic drugs. A real time and quantitative follow-up of MCTS with simple and robust readouts to evaluate drug efficacy is still missing. Here, we evaluate the chemotherapeutic drug 5-Fluorouracil (5-FU) response on the growth and integrity of MCTS two days after treatment of MCTS and for three colorectal carcinoma cell lines with different cohesive properties (HT29, HCT116 and SW480)...

Cultivar mixtures can be used to improve the sustainability of disease management within farming systems by growing cultivars that differ in their disease resistance level in the same field. The impact of canopy aerial architecture on rain-splash dispersal could amplify disease reduction within mixtures. We designed a controlled conditions experiment to study single splash-dispersal events and their consequences for disease. We quantified this impact through the spore interception capacities of the component cultivars of a mixture...

Protected Areas are a key component of nature conservation. They can play an important role in counterbalancing the impacts of ecosystem degradation. For an optimal protection of a Protected Area it is essential to account for the variables underlying the major Ecosystem Services an area delivers, and the threats upon them. Here we show that the perception of these important variables differs markedly between scientists and managers of Protected Areas in mountains and transitional waters. Scientists emphasise variables of abiotic and biotic nature, whereas managers highlight socio-economic, cultural and anthropogenic variables...

PURPOSE OF REVIEW: To provide an update on the relevant and recent studies on whole-body computed tomography (WBCT) imaging of severely injured patients. RECENT FINDINGS: The advantages of WBCT in time saving, diagnostic accuracy and even in survival have been proven in numerous studies. WBCT can also be beneficial in haemodynamically unstable major trauma patients. The CT scanner should be located close to the emergency department or even in the trauma room. The issue of radiation is still quite important, however, iterative as well as split-bolus protocols can nowadays reduce radiation significantly...

Research shows that chronic pain is related to cortical alterations that can be reflected in reduced tactile acuity, but whether acute pain perception influences tactile acuity has not been tested. Considering the biological role of nociception, it was hypothesized that nociceptive pain will lead to a rapid improvement in tactile acuity and that this effect is correlated with pain intensity and pain distribution. In this randomised double-blind controlled experiment (trial no. NCT03021278), healthy participants were exposed to one of three experimental conditions: acute, nociceptive low back pain induced by saline injection, a sham-injection (without piercing the skin) potentially inducing nocebo pain, or no intervention...

We investigated the influence of sociodemographic factors, acculturation, ethnicity, health status, and spirituality on older adults' health-related decisions when confronted with a choice between competing options. The sample included 451 participants: African Americans (15.74%), Afro-Caribbeans (25.5%), European Americans (36.36%), and Hispanic Americans (22.4%). Compared with others, European Americans and Hispanic Americans favored quality of life over a lengthy life. Sociodemographic factors, acculturation, ethnicity, health status, and spirituality accounted for variations of decisions...

Purpose The early integration of oncology and palliative care (EIPC) improves quality of life (QOL) and mood for patients with advanced cancer. However, the mechanisms by which EIPC benefits these outcomes remain unclear. We therefore examined whether EIPC improved patients' coping strategies and if changes in coping accounted for intervention effects on QOL and depressive symptoms. Patients and Methods For this secondary analysis of an EIPC trial, we examined data from 350 patients with newly diagnosed incurable lung or GI cancer...

The field of social work seeks to enhance human well-being by addressing the needs of people living in poverty. Three billion people around the world use the internet daily, and 65% of them use social media. This article qualitatively identifies emergent themes about the lived experiences of poverty from people who reported either being poor or having have been poor, using selected social media posts (N = 1,495) on the website Reddit. We found that the experiences of poverty bring arduousness and hardship, which necessitates an arsenal of survival strategies and skills...

International guidelines for the conduct of research with human participants, such as those put forth by the Council for International Organizations of Medical Sciences (CIOMS, 2002), recommend that research review committees account for social risk and benefits to society in their review of proposed research. What do the concepts "social" and "society" mean in the context of the review of human participants research? Here we analyze concepts of social and society to define the terms: social harm, social risk, social benefit, and benefits to society...

The United States has a high stake in China’s serious food safety problem, as food products of Chinese origin have dominated the U.S. food market in numerous areas and continue to grow. The conclusion of the U.S.-China Food Safety Agreement (“the Agreement”) has allowed FDA to strengthen regulatory cooperation with its Chinese counterpart in various aspects. The Agreement also paves the way for the implementation of the new regulatory tools incorporated in FSMA, especially in the cross-border context...

This study examined the effectiveness of engineering controls to reduce contaminant concentrations in a swine farrowing room during winter in the U.S. Midwest. Over two winters, changes in air quality were evaluated following installation of a 1700 m3 h-1 (1000 cfm) recirculating ventilation system to provide 5.4 air exchanges per hour. This system incorporated one of two readily available dust control systems, one based on filtration and the other on cyclonic treatment. A second treatment evaluated reductions in carbon dioxide (CO2) associated with replacement of standard, unvented gas-fired heaters with new vented heaters, installed between the two winter test periods...
