    Experiencing WPS services in several application domains: opportunities and challenges ====================================================================================== The implementation of OGC web services and specifically of WPS services revealed itself as a key aspect in order to encourage openess attitude of scientific investigators within several application domains. It can benefit scientific research under different regards, even considering the possibility to promote interoperability, modularity, and the possibility opened by web modeling and the workflow paradigm explotation. Nevertheless it is still a challenging activity and specifically processing services still seem being at an early stage of maturity. This work is about exploitation activities conducted within the GEO GEOSS AIP-8 call by focusing on several applications, such as biodiversity, flood monitoring and soil moisture computation, with implementations based on the pyWPS framework for WPS 1.0 as available at the time of this work. We will present results, lessons learnt and limits found in using those services for distributing demo processing models, along with pro and cons in our experience.

    A decrease in insulin sensitivity enhances adipose tissue lipolysis helping early lactation cows counteracting their energy deficit. However, excessive lipolysis poses serious health risks for cows, and its underlying mechanisms are not clearly understood. The present study used targeted ESI-LC-MS/MS-based metabolomics and indirect insulin sensitivity measurements to evaluate metabolic alterations in the serum of dairy cows of various parities experiencing variable lipolysis early postpartum. Thirty (12 primiparous and 18 multiparous) cows of Holstein Friesian and Simmental breeds, fed the same diet and kept under the same management conditions, were sampled at d 21 postpartum and classified as low (n = 10), medium (n = 8), and high (n = 12) lipolysis groups, based on serum concentration of nonesterified fatty acids. Overall, excessive lipolysis in the high group came along with impaired estimated insulin sensitivity and characteristic shifts in acylcarnitine, sphingomyelin, phosphatidylcholine and lysophospholipid metabolome profiles compared to the low group. From the detected phosphatidylcholines mainly those with diacyl-residues showed differences among lipolysis groups. Furthermore, more than half of the detected sphingomyelins were increased in cows experiencing high lipomobilization. Additionally, strong differences in serum acylcarnitines were noticed among lipolysis groups. The study suggests an altered serum phospholipidome in dairy cows associated with an increase in certain long-chain sphingomyelins and the progression of disturbed insulin function. In conclusion, the present study revealed 37 key metabolites as part of alterations in the synthesis or breakdown of sphingolipids and phospholipids associated with lowered estimated insulin sensitivity and excessive lipolysis in early-lactating cows.

    Using participatory design, we developed and deployed a mobile Virtual Health Record (VHR) on a personal digital assistant (PDA) together with experienced homecare staff. To assess transferability to a second setting and usability when used by novice users with limited system education the application was tested in a usability lab. Eight participants from another homecare district performed tasks related to daily homecare work using the VHR. Test protocols were analyzed with regard to effectiveness, potential usability problems and user satisfaction. Usability problems having impact on system performance and contextual factors affecting system transferability were uncovered. Questionnaires revealed that the participants frequently used computers, but never PDAs. Surprisingly there were only minor differences in input efficiency between novice and experienced users. The participants were overall satisfied with the application. However, transfer to another district can not be performed, unless by means of careful field observations of contextual differences.

    We aimed to assess comprehensively the prevalence of perinatal risks experienced by a potentially high-risk yet understudied population of children domestically adopted in the United States. Data are from participant report and medical records from mothers (n = 580) who completed a domestic adoption placement with nonrelatives at or near birth (Mean placement age = 7 days). We describe a comprehensive measure of perinatal risks, including divergences from previous assessment tools and the incorporation of multiple reporters, and report the prevalence of various types of perinatal risks. The prevalence of each specific risk factor was generally low, although several risks were more prevalent in this sample than estimates from nationally representative publicly available data. Nearly the entire sample (99%) experienced some type of risk exposure. Birth mothers who placed their children for adoption domestically in the US experience higher levels of perinatal risks than the national average, but not for all specific types of risk. Thus, the developmental trajectories of children adopted domestically may systematically differ from the general population to the extent that these specific perinatal risks impact development.

    ABSTRACT Objective: to review and synthesize qualitative research on the links between early-life stress and addiction behaviours in adulthood. Method: metasynthesis to review qualitative research findings based on procedures that outline how to identify themes or constructs across studies in a specific area. Comprehensive searches of multiple electronic databases were performed. The initial search yielded 1050 articles and the titles and abstracts were screened for inclusion based on predetermined criteria. Thirty-eight full text, peer-reviewed articles were retrieved and assessed by three independent reviewers. Twelve articles were eligible for full review and appraised using the Critical Appraisal Skills Programme (CASP) tools. Results: the findings revealed that clear associations exist between early-life stress and addictive behaviours in adulthood, such as between trauma in childhood, violence, and addictive behaviours. A common theme in the findings indicates that participants turn to addictive substances as a way of strategically coping with stressful childhood experiences, regardless of the harmful side effects or detrimental social outcomes. Conclusion: it can be inferred that addiction may be viewed as a way to deal with adversity in childhood and that there is an interrelationship between addiction, domestic violence and crime.

  16. Neurogenic function in rats with unilateral hippocampal sclerosis that experienced early-life status epilepticus

    Status epilepticus in the adult brain invariably causes an increase in hippocampal neurogenesis and the appearance of ectopic cells and this has been implicated as a causal factor in epileptogenesis. The effect of status epilepticus on neurogenesis in the developing brain is less well characterized and models of early-life seizures typically do not reproduce the hippocampal damage common to human mesial temporal sclerosis. We recently reported that evoking status epilepticus by intra-amygdala microinjection of kainic acid in post-natal (P) day 10 rats caused substantial acute neuronal death within the ipsilateral hippocampus and rats later developed unilateral hippocampal sclerosis and spontaneous recurrent seizures. Here, we examined the expression of a selection of genes associated with neurogenesis and assessed neurogenic function in this model. Protein levels of several markers of neurogenesis including polysialic acid neural cell adhesion molecule, neuroD and doublecortin were reduced in the hippocampus three days after status epilepticus in P10 rats. In contrast, protein levels of neurogenesis markers were similar to control in rats at P55. Pulse-chase experiments using thymidine analogues suggested there was a reduction in new neurons at 72 h after status epilepticus in P10 rats, whereas numbers of new neurons labelled in epileptic rats at P55 with hippocampal sclerosis were similar to controls. The present study suggests that status epilepticus in the immature brain suppresses neurogenesis but the neurogenic potential is retained in animals that later develop hippocampal sclerosis.

    Early postnatal overnutrition results in a predisposition to develop obesity due in part to hypothalamic and sympathetic dysfunction. Potential involvement of another major regulatory system component - the vagus nerve - has not been examined. Moreover, feeding disturbances have rarely been investigated prior to development of obesity when confounds due to obesity are minimized. To examine these issues, litters were culled on the day of birth to create small litters (SL; overnutrition), or normal-size litters (NL; normal nutrition). Body weight, fat pad weight, meal patterns, and vagal sensory duodenal innervation were compared between SL and NL adult mice prior to development of obesity. Meal patterns were studied 18 hour/day for 3 weeks using a balanced diet. Then vagal mechanoreceptors were labeled using anterograde transport of wheatgerm agglutinin-horseradish peroxidase injected into the nodose ganglion and their density and morphology were examined. Between postnatal day 1 and weaning, body weight of SL mice was greater than for NL mice. By young adulthood it was similar in both groups, whereas SL fat pad weight was greater in males, suggesting postnatal overnutrition produced a predisposition to obesity. SL mice exhibited increased food intake, decreased satiety ratio, and increased first meal rate (following mild food deprivation) compared to NL mice, suggesting postnatal overnutrition disrupted satiety. The density and structure of intestinal IGLEs appeared similar in SL and NL mice. Thus, although a vagal role cannot be excluded, our meal parameter and anatomical findings provided no evidence for significant postnatal overnutrition effects on vagal gastrointestinal afferents.

    Early treatment failure (ETF) in follicular lymphoma (FL), defined as relapse or progression within 2 years of frontline chemoimmunotherapy, is a newly recognized marker of poor survival and identifies a high-risk group of patients with an expected 5-year overall survival (OS) rate of approximately 50%. Transplantation is an established option for relapsed FL, but its efficacy in this specific ETF FL population has not been previously evaluated. This study compared autologous hematopoietic stem cell transplantation (auto-HCT) with either matched sibling donor (MSD) or matched unrelated donor (MUD) allogeneic hematopoietic cell transplantation (allo-HCT) as the first transplantation approach for patients with ETF FL (age ≥ 18 years) undergoing auto-HCT or allo-HCT between 2002 and 2014. The primary endpoint was OS. The secondary endpoints were progression-free survival, relapse, and nonrelapse mortality (NRM). Four hundred forty FL patients had ETF (auto-HCT, 240; MSD hematopoietic stem cell transplantation [HCT], 105; and MUD HCT, 95). With a median follow-up of 69 to 73 months, the adjusted probability of 5-year OS was significantly higher after auto-HCT (70%) or MSD HCT (73%) versus MUD HCT (49%; P = .0008). The 5-year adjusted probability of NRM was significantly lower for auto-HCT (5%) versus MSD (17%) or MUD HCT (33%; P < .0001). The 5-year adjusted probability of disease relapse was lower with MSD (31%) or MUD HCT (23%) versus auto-HCT (58%; P < .0001). Patients with high-risk FL, as defined by ETF, undergoing auto-HCT for FL have low NRM and a promising 5-year OS rate (70%). MSD HCT has lower relapse rates than auto-HCT but similar OS.

    In order to prevent the over-representation of young drivers in car crashes, France instated an early driver training from the age of 16, but the positive effects of this opportunity have not yet been proven. Three groups of male drivers (12 subjects each) were confronted with some prototypical accident scenarios introduced in a simulated urban circuit. The first and second groups were composed of young drivers having less than one month of driving licence; twelve have had a traditional learning course, and twelve had followed, in addition to the initial course, an early driver training under the supervision of an adult. The third group was composed of experienced drivers. Strategies of the three groups were analyzed through their response time, speed and maneuvers. No difference appeared across groups regarding obstacle detection. But traditionally-trained drivers' position control was more conservative than the two others groups, which were more likely to involve efficient evasive action. The exposure gained during early training could thus increase the development of visuo-motor coordination and involve better skills in case of difficult situations. Others accidents' scenarios could be used to confront young drivers with difficult situations not commonly encountered in natural driving.

  1. Experiencing El Niño conditions during early life reduces recruiting probabilities but not adult survival

    2018-01-01

    In wild long-lived animals, analysis of impacts of stressful natal conditions on adult performance has rarely embraced the entire age span, and the possibility that costs are expressed late in life has seldom been examined. Using 26 years of data from 8541 fledglings and 1310 adults of the blue-footed booby (Sula nebouxii), a marine bird that can live up to 23 years, we tested whether experiencing the warm waters and food scarcity associated with El Niño in the natal year reduces recruitment or survival over the adult lifetime. Warm water in the natal year reduced the probability of recruiting; each additional degree (°C) of water temperature meant a reduction of roughly 50% in fledglings' probability of returning to the natal colony as breeders. Warm water in the current year impacted adult survival, with greater effect at the oldest ages than during early adulthood. However, warm water in the natal year did not affect survival at any age over the adult lifespan. A previous study showed that early recruitment and widely spaced breeding allow boobies that experience warm waters in the natal year to achieve normal fledgling production over the first 10 years; our results now show that this reproductive effort incurs no survival penalty, not even late in life. This pattern is additional evidence of buffering against stressful natal conditions via life-history adjustments. PMID:29410788

    When mental health crisis situations in the community are poorly handled, it can result in physical and emotional injuries. The purpose of this study was to ascertain the experiences and opinions of consumers about the way police and mental health services worked together, specifically via the Alfred Police and Clinical Early Response (A-PACER) model, to assist people experiencing a mental health crisis. Semi-structured in-depth interviews were conducted with 12 mental health consumers who had direct contact with the A-PACER team between June 2013 and March 2015. The study highlighted that people who encountered the A-PACER team generally valued and saw the benefit of a joint police-mental health clinician team response to a mental health crisis situation in the community. In understanding what worked well in how the A-PACER team operated, consumers perspectives can be summarized into five themes: communication and de-escalation, persistence of the A-PACER team, providing a quick response and working well under pressure, handover of information, and A-PACER helped consumers achieve a preferred outcome. All consumers acknowledged the complementary roles of the police officer and mental health clinician, and described the A-PACER team's supportive approach as critical in gaining their trust, engagement and in de-escalating the crises. Further education and training for police officers on how to respond to people with a mental illness, increased provision of follow-up support to promote rehabilitation and prevent future crises, and measures to reduce public scrutiny for the consumer when police responded, were proposed opportunities for improvement. © 2016 Australian College of Mental Health Nurses Inc.

    Adverse childhood experiences (ACE) may influence stress and affective processing in adulthood. Animal and human studies show enhanced startle reflexivity in adult participants with ACE. This study examined the impact of one of the most common ACE, parental divorce, on startle reflexivity in adulthood. Affective modulation of acoustically-elicited startle eye blink was assessed in a group of 23 young adults with self-reported history of parental divorce, compared to an age- and sex-matched control group (n=18). Foreground pictures were either aversive (e.g. mutilation and injury), standard appetitive (e.g. erotic, recreational sport), or nurture pictures (e.g. related to early life, parental care), intermixed with neutral pictures (e.g. household objects), and organized in three valence blocks delivered in a balanced, pseudo-randomized sequence. During picture viewing startle eye blinks were elicited by binaural white noise bursts (50ms, 105 dB) via headphones and recorded at the left orbicularis oculi muscle via EMG. A significant interaction of group×picture valence (p=0.01) was observed. Contrast with controls revealed blunted startle responsiveness of the ACE group during presentation of aversive pictures, but enhanced startle during presentation of nurture-related pictures. No group differences were found during presentation of standard appetitive pictures. ACE participants rated nurture pictures as more arousing (p=0.02) than did control participants. Results suggest that divorce in childhood led to altered affective context information processing in early adulthood. When exposed to unpleasant (vs. neutral) pictures participants with ACE showed less startle potentiation than controls. Nurture context, however, potentiated startle in ACE participants, suggesting visual cuing to activate protective behavioral responses. Copyright © 2017 Elsevier B.V. All rights reserved.

In this study, 48 patients with early RA, aged 20-63 years, were interviewed about participation restrictions using the critical incident technique. Information from transcribed interviews was converted into dilemmas and linked to International Classification of Functioning, Disability, and Health (ICF) participation codes. The emotions described were condensed and categorized. Hopelessness and sadness were described when trying to perform daily activities such as getting up in the mornings and getting dressed, or not being able to perform duties at work. Sadness was experienced in relation to not being able to continue leisure activities or care for children. Examples of fear descriptions were found in relation to deteriorating health and fumble fear, which made the individual withdraw from activities as a result of mistrusting the body. Anger and irritation were described in relation to domestic and employed work but also in social relations where the individual felt unable to continue valued activities. Shame or embarrassment was described when participation restrictions became visible in public. Feelings of grief, aggressiveness, fear, and shame are emotions closely related to participation restrictions in everyday life in early RA. Emotions related to disability need to be addressed both in clinical settings in order to optimize rehabilitative multi-professional interventions and in research to achieve further knowledge.

  7. Childhood misery and disease in later life: the effects on mortality in old age of hazards experienced in early life, southern Sweden, 1760-1894.

    This paper assesses the importance of early-life conditions relative to the prevailing conditions for mortality by cause of death in later life using historical data for four rural parishes in southern Sweden for which both demographic and economic data are very good. Longitudinal demographic data for individuals are combined with household socio-economic data and community data on food costs and the disease load using a Cox regression framework. We find strong support for the hypothesis that the disease load experienced during the first year of life has a strong impact on mortality in later life, in particular on the outcome of airborne infectious diseases. Hypotheses about the effects of the disease load on mothers during pregnancy and access to nutrition during the first years of life are not supported. Contemporary short-term economic stress on the elderly was generally of limited importance although mortality varied by socio-economic group.

    Research into the effectiveness of therapeutic interventions for older children who have experienced multiple forms of trauma within the context of their early development is scant. This article explores the effectiveness of Neuro-Physiological Psychotherapy (NPP): a wrap-around multi-disciplinary, neuro-sequential, attachment-focussed intervention for children and families who present with multiple, clinically significant, emotional and behavioural difficulties. In total, 31 young people and their adoptive parents took part in the study. Baseline measures were repeated and parents and children interviewed. An assessment of the parent/child relationship and child attachment was undertaken but not analysed for this article. Analysis of the repeated measures received statistically significant changes in behavioural regulation, metacognitive executive functioning and externalising and internalising difficulties, alongside an improvement in thought and social problems. An analysis of the parent interviews provided positive results in terms of the children's engagement in education, an absence of further mental health diagnosis or involvement in the criminal justice system. Further hypotheses are posited regarding the impact of the treatment and further research into the effectiveness of the model outlined. © The Author(s) 2016.

    Tipranavir, a non-peptidic protease inhibitor which shows in vitro efficacy against some HIV-1-resistant strains, can be used in salvage therapies for multi-experienced HIV patients due to its peculiar resistance profile including 21 mutations at 16 protease positions according to International AIDS Society (IAS). Other genotypic scores, however, which attribute a different weight to single amino-acid substitutions, have been recently proposed. To validate the clinical utility of four different genotypic scores for selecting tipranavir responders, the baseline resistance pattern of 176 HIV heavily experienced patients was correlated with virological success (HIV-RNA<50 copies/ml) after 24 weeks of a new treatment based on tipranavir/ritonavir. Virological suppression after 24 weeks was reached by 42.5% of patients. With univariate analysis, genotypic scores were all associated with outcome but showed a low accuracy with ROC analysis, with the weighted score (WS) by Scherer et al. demonstrating the best performance with an AUC of 68%. Only 52% of patients classified as susceptible (WS< or =3) responded to the new therapy. The following variables were significantly associated (p<0.05) to failure with multivariate analysis: WS, log peak of HIV-RNA, IAS mutations: L33F, I54AMV, Q58E, and non-IAS mutation: N37DES. On the contrary, the use of T20 in T20-naïve patients and the V82AFSI and F53LY non-IAS mutations were associated with virological success. The study suggests that even if the "weighted" scores are able to interpret correctly the antiretroviral resistance profile of multi-experienced patients, it is difficult to individuate a cut-off which can be easily applied to this population for discriminating responders.

    2015-03-01

    Since its earliest days, cinema has been used in the teaching of neurology both to illustrate the professor's explanations and to make learning easier for students. To analyse some of the first applications of cinema to the teaching and learning of neurology. Shortly after the birth of the film projector it became apparent that it could be a valuable aid in teaching medicine, and especially neurology. Initially, actual recordings made by doctors themselves were used, and later documentaries, short films and feature films were employed as means of showing diagnostic and therapeutic methods, as well as different pathological signs, such as movement disorders. The intention was not to replace other methodologies but instead to complement them and to make the process of acquiring knowledge easier. Applying cinema in teaching is a useful way to portray the contents of different subjects, especially in the field of neurology, and to favour the acquisition of both specific and cross-disciplinary competences, with very positive results being obtained among students.

  13. Plasma ceramides are elevated in overweight Holstein dairy cows experiencing greater lipolysis and insulin resistance during the transition from late pregnancy to early lactation.

    Insulin resistance is a homeorhetic adaptation to parturition in dairy cows transitioning from late pregnancy to early lactation. An increase in prepartum adiposity can predispose periparturient cows to greater lipolysis and insulin resistance, thus increasing the risk for metabolic disease. Mechanisms mediating the development of insulin resistance in overweight peripartal dairy cows may depend on ceramide metabolism. The sphingolipid ceramide accumulates in plasma and tissues of overweight monogastric animals, and facilitates saturated fatty acid-induced insulin resistance. Considering this evidence, we hypothesized that plasma ceramides would be elevated in periparturient dairy cattle and that these sphingolipids would correlate with the magnitude of lipolysis and insulin resistance. To test our central hypothesis, multiparous Holstein cows were allocated into 2 groups according to their body condition score (BCS) at d -30 prepartum: lean (BCS <3.0; n=10) or overweight (BCS >4.0; n=11). Blood samples were collected at d -45, -30, -15, and -7, relative to expected parturition, and at d 4 postpartum. Plasma glucose, insulin, nonesterified fatty acids (NEFA), and β-hydroxybutyrate (BHBA) concentrations were measured, and insulin sensitivity was estimated. The concentrations of individual plasma ceramide and glycosylated ceramide were determined using liquid chromatography-based mass spectrometry. Results demonstrated that greater adiposity was associated with a greater loss in body condition during late pregnancy. Overweight cows had greater circulating concentrations of glucose, insulin, and NEFA, and lower insulin sensitivity relative to lean cows. We detected 30 different sphingolipids across 6 lipid classes with acyl chains ranging from 16 to 26 carbons. The most abundant plasma sphingolipids detected were C24:0-ceramide, C24:0-monohexosylceramide, and C16:0-lactosylceramide. Plasma concentrations of total ceramide and monohexosylceramide increased as

    Rapid assessment of damage potential and size of an earthquake at the station is highly demanded for onsite earthquake early warning. We study the application of τc*Pd for its estimation on the earthquake size using 123 events recorded by the borehole stations of KiK-net in Japan. The new type of earthquake size determined by τc*Pd is more related to the damage potential. We find that τc*Pd provides another parameter to measure the size of earthquake and the threshold to warn strong ground motion.

In recent years, it has become necessary to factor in the effects of a changing climate as well. There has also been a growing appreciation of the linkage between food security and water availability. In 2009, Famine Early Warning Systems Network (FEWS NET) science partners began developing land surface modeling (LSM) applications to address these needs. With support from the NASA Applied Sciences Program, an instance of the Land Information System (LIS) was developed to specifically support FEWS NET. A simple crop water balance model (GeoWRSI) traditionally used by FEWS NET took its place alongside the Noah land surface model and the latest version of the Variable Infiltration Capacity (VIC) model, and LIS data readers were developed for FEWS NET precipitation forcings (NOAA's RFE and USGS/UCSB's CHIRPS). The resulting system was successfully used to monitor and project soil moisture conditions in the Horn of Africa, foretelling poor crop outcomes in the OND 2013 and MAM 2014 seasons. In parallel, NOAA created another instance of LIS to monitor snow water resources in Afghanistan, which are an early indicator of water availability for irrigation and crop production. These successes have been followed by investment in LSM implementations to track and project water availability in Sub-Saharan Africa and Yemen, work that is now underway. Adoption of

    Performance of earthquake early warning systems suffers from false alerts caused by local impulsive noise from natural or anthropogenic sources. To mitigate this problem, we train a generative adversarial network (GAN) to learn the characteristics of first-arrival earthquake P waves, using 300,000 waveforms recorded in southern California and Japan. We apply the GAN critic as an automatic feature extractor and train a Random Forest classifier with about 700,000 earthquake and noise waveforms. We show that the discriminator can recognize 99.2% of the earthquake P waves and 98.4% of the noise signals. This state-of-the-art performance is expected to reduce significantly the number of false triggers from local impulsive noise. Our study demonstrates that GANs can discover a compact and effective representation of seismic waves, which has the potential for wide applications in seismology.

    Initial insults to kidney allografts, characterized by infiltration of mononuclear inflammatory cells, contribute to chronic allograft nephropathy. Chemokines such as RANTES (regulated upon activation, normal T cell expressed) are thought to be responsible for the recruitment and activation of infiltrating cells. The present study investigated whether early application of Met-RANTES, a chemokine receptor antagonist that blocks the effects of RANTES, can protect renal allografts from long-term deterioration. Fisher (F344) rat kidneys were orthotopically transplanted into Lewis recipients and treated with cyclosporine A (1.5 mg/kg/day) for the first 10 days following transplantation, together with either Met-RANTES at 40 microg/day, 200 microg/day or vehicle for the first 7 days. Animals were harvested at 2 and 28 weeks after transplantation for histologic, immunohistologic and molecular analysis. Met-RANTES treatment reduced the infiltration of lymphocytes and macrophages in allografts at 2 weeks after transplantation, accompanied by decreased mRNA expression of interleukin (IL)-2, IL-1beta, tumor necrosis factor-alpha (TNF-alpha) and RANTES. At post-transplantation week 28, Met-RANTES treatment at high and low doses reduced urinary protein excretion and significantly ameliorated glomerulosclerosis, interstitial fibrosis, tubular atrophy, intimal proliferation of graft arteries and mononuclear cell infiltration. However, creatinine clearance was not influenced by Met-RANTES. Furthermore, Met-RANTES suppressed the mRNA expression of transforming growth factor-beta (TGF-beta) and platelet-derived growth factor-B (PDGF-B). Blockade of chemokine receptors by Met-RANTES diminishes early infiltration and activation of mononuclear cells in the grafts, and thus reduces the pace of chronic allograft nephropathy.

    other [4], some authors have claimed that the 37Cl/35Cl ratio of geological samples obtained by TIMS technique are, in general, misleadingly too high and variable compared to those of IRMS [3]. For eample, almost no differences of Cl isotope composition were observed among mantle materials and carbonaceous meteorites by [3]. On the other hand, according to more recent IRMS work [2], significant Cl isotope variations are confirmed for mantle materials. Therefore, additional careful investigation of Cl isotope analyses are now required to confirm real chlorine isotope variations for planetary materials including carbonaceous chondrites [5]. In order to clarify the stable chlorine isotope features of early solar system materials, we have initiated development of the TIMS technique at NASA JSC applicable to analysis of small amounts of meteoritic and planetary materials. We report here the current status of chlorine isotope analysis at NASA JSC.

  17. The Successful Application of a National Peer Advisory Committee for Physicians Who Provide Salvage Regimens to Heavily Antiretroviral-Experienced Patients in Mexican Human Immunodeficiency Virus Clinics

    PubMed Central

    Calva, Juan J.; Sierra-Madero, Juan; Soto-Ramírez, Luis E.; Aguilar-Salinas, Pedro

    2014-01-01

    Background  Designing optimal antiretroviral (ARV) salvage regimens for multiclass drug-resistant, human immunodeficiency virus (HIV)-infected patients demands specific clinical skills. Our aim was to assess the virologic and immunologic effects of the treatment recommendations drafted by a peer advisory board to physicians caring for heavily ARV-experienced patients. Methods  We conducted a nationwide, HIV clinic-based, cohort study in Mexico. Adults infected with HIV were assessed for a median of 33 months (interquartile range [IQR] = 22–43 months). These patients had experienced the virologic failure of at least 2 prior ARV regimens and had detectable viremia while currently being treated; their physicians had received therapeutic advice, by a panel of experts, regarding the ARV salvage regimen. The primary endpoint was the incidence of loss of virologic response (plasma HIV-RNA levels of <200 copies per mL, followed by levels above this threshold) during the follow-up assessment using an observed-failure competing risks regression analysis. Results  A total of 611 patients were observed (median ARV therapy exposure = 10.5 years; median prior regimens = 4). The probabilities of virologic failure were 11.9%, 14.4%, 16.9%, and 19.4% at the 12-, 24-, 36-, and 48-month follow-up assessments, respectively. Of the 531 patients who achieved a confirmed plasma HIV-RNA level below 200 copies per mL, the median increase in blood CD4+ T-cell count was 162 cells per mL (IQR = 45–304 cells per mL). Conclusions  In routine practice, a high rate of patients with extensive ARV experience, who received an optimized salvage regimen recommended by a peer advisory committee, achieved a long-term sustained virologic response and immune reconstitution.

  3. Application of Early Nutrition Support in Neurosurgical Coma Patients.

    Ren, Guoqin

    2015-12-01

    The present study was conducted to investigate the clinical efficacy of early parenteral and enteral nutrition (PN + EN) support in neurosurgical coma patients. Eighty cases of neurosurgical coma patients were randomly divided into intervention group and control group. The intervention group received early PN + EN support, and the control group received only total enteral nutritional (TEN) support. The levels of hemoglobin (HGB), serum albumin (ALB), prealbumin (PA), and retinol-binding protein (RBP) in two groups on days 1, 10, and 20 were observed. The incidences of pneumonia, stress ulcer, abnormal liver function, abdominal distension, and diarrhea between two groups were also compared. Results found that, on day 10, compared with the control group, the levels of HGB, PA, and RBP in the intervention group were significantly increased (P < 0.05). On day 20, ALB in the intervention group significantly increased (P < 0.05), and the incidences of pneumonia, abdominal distension, and diarrhea in the intervention group were significantly lower than those in the control group (P < 0.05). Compared with only TEN support, early PN + EN support can obviously improve the nutritional status of neurosurgical coma patients and reduce the occurrence of complications.

  15. TRMM Applications for Rainfall-Induced Landslide Early Warning

    NASA Astrophysics Data System (ADS)

    Dok, A.; Fukuoka, H.; Hong, Y.

    2012-04-01

    Early warning system (EWS) is the most effective method in saving lives and reducing property damages resulted from the catastrophic landslides if properly implemented in populated areas of landslide-prone nations. For predicting the occurrence of landslides, it requires examination of empirical relationship between rainfall characteristics and past landslide occurrence. In developed countries like Japan and the US, precipitation is monitored by rain radars and ground-based rain gauge matrix. However, in developing regions like Southeast Asian countries, very limited number of rain gauges is available, and there is no implemented methodology for issuing effective warming of landslides yet. Correspondingly, satellite precipitation monitoring could be therefore a possible and promising solution for launching landslide quasi-real-time early warning system in those countries. It is due to the fact that TMPA (TRMM Multi-satellite Precipitation Analysis) can provides a globally calibration-based sequential scheme for combining precipitation estimates from multiple satellites, and gauge analyses where feasible, at fine scales (3-hourly with 0.25°x0.25° spatial resolution). It is available both after and in quasi-real time, calibrated by TRMM Combined Instrument and TRMM Microwave Imager precipitation product. However, validation of ground based rain gauge and TRMM satellite data in the vulnerable regions is still not yet operative. Snake-line/Critical-line and Soil Water Index (SWI) are used for issuing warning of landslide occurrence in Japan; whereas, Caine criterion is preferable in Europe and western nations. Herewith, it presents rainfall behavior which took place in Beichuan city (located on the 2008 Chinese Wenchuan earthquake fault), Hofu and Shobara cities in Japan where localized heavy rainfall attacked in 2009 and 2010, respectively, from TRMM 3B42RT correlated with ground based rain gauge data.

    Automatic diagnosis of plant disease is important for plant management and environmental preservation in the future. The objective of this study is to use multispectral reflectance measurements to make an early discrimination between the healthy and infected plants by the strain of tobacco mosaic virus (TMV-U1) infection. There were reflectance changes in the visible (VIS) and near infrared spectroscopy (NIR) between the healthy and infected plants. Discriminant models were developed using discriminant partial least squares (DPLS) and Mahalanobis distance (MD). The DPLS models had a root mean square error of calibration (RMSEC) of 0.397 and correlation coefficient (r) of 0.59 and the MD model correctly classified 86.7% healthy plants and up to 91.7% infected plants.

  17. Assessing the Applicability of Earthquake Early Warning in Nicaragua.

    Nicaragua, like much of Central America, suffers from frequent damaging earthquakes (6 M7+ earthquakes occurred in the last 100 years). Thrust events occur at the Middle America Trench where the Cocos plate subducts by 72-81 mm/yr eastward beneath the Caribbean plate. Shallow crustal events occur on-shore, with potential extensive damage as demonstrated in 1972 by a M6.2 earthquake, 5 km beneath Managua. This seismotectonic setting is challenging for Earthquake Early Warning (EEW) because the target events derive from both the offshore seismicity, with potentially large lead times but uncertain locations, and shallow seismicity in close proximity to densely urbanized areas, where an early warning would be short if available at all. Nevertheless, EEW could reduce Nicaragua's earthquake exposure. The Swiss Development and Cooperation Fund and the Nicaraguan Government have funded a collaboration between the Swiss Seismological Service (SED) at ETH Zurich and the Nicaraguan Geosciences Institute (INETER) in Managua to investigate and build a prototype EEW system for Nicaragua and the wider region. In this contribution, we present the potential of EEW to effectively alert Nicaragua and the neighbouring regions. We model alert time delays using all available seismic stations (existing and planned) in the region, as well as communication and processing delays (observed and optimal) to estimate current and potential performances of EEW alerts. Theoretical results are verified with the output from the Virtual Seismologist in SeisComP3 (VS(SC3)). VS(SC3) is implemented in the INETER SeisComP3 system for real-time operation and as an offline instance, that simulates real-time operation, to record processing delays of playback events. We compare our results with similar studies for Europe, California and New Zealand. We further highlight current capabilities and challenges for providing EEW alerts in Nicaragua. We also discuss how combining different algorithms, like e.g. VS

  2. Rapid Earthquake Magnitude Estimation for Early Warning Applications

    NASA Astrophysics Data System (ADS)

    Goldberg, Dara; Bock, Yehuda; Melgar, Diego

    2017-04-01

    Earthquake magnitude is a concise metric that provides invaluable information about the destructive potential of a seismic event. Rapid estimation of magnitude for earthquake and tsunami early warning purposes requires reliance on near-field instrumentation. For large magnitude events, ground motions can exceed the dynamic range of near-field broadband seismic instrumentation (clipping). Strong motion accelerometers are designed with low gains to better capture strong shaking. Estimating earthquake magnitude rapidly from near-source strong-motion data requires integration of acceleration waveforms to displacement. However, integration amplifies small errors, creating unphysical drift that must be eliminated with a high pass filter. The loss of the long period information due to filtering is an impediment to magnitude estimation in real-time; the relation between ground motion measured with strong-motion instrumentation and magnitude saturates, leading to underestimation of earthquake magnitude. Using station displacements from Global Navigation Satellite System (GNSS) observations, we can supplement the high frequency information recorded by traditional seismic systems with long-period observations to better inform rapid response. Unlike seismic-only instrumentation, ground motions measured with GNSS scale with magnitude without saturation [Crowell et al., 2013; Melgar et al., 2015]. We refine the current magnitude scaling relations using peak ground displacement (PGD) by adding a large GNSS dataset of earthquakes in Japan. Because it does not suffer from saturation, GNSS alone has significant advantages over seismic-only instrumentation for rapid magnitude estimation of large events. The earthquake's magnitude can be estimated within 2-3 minutes of earthquake onset time [Melgar et al., 2013]. We demonstrate that seismogeodesy, the optimal combination of GNSS and seismic data at collocated stations, provides the added benefit of improving the sensitivity of

  4. Application of Seismic Array Processing to Tsunami Early Warning

    NASA Astrophysics Data System (ADS)

    An, C.; Meng, L.

    2015-12-01

    Tsunami wave predictions of the current tsunami warning systems rely on accurate earthquake source inversions of wave height data. They are of limited effectiveness for the near-field areas since the tsunami waves arrive before data are collected. Recent seismic and tsunami disasters have revealed the need for early warning to protect near-source coastal populations. In this work we developed the basis for a tsunami warning system based on rapid earthquake source characterisation through regional seismic array back-projections. We explored rapid earthquake source imaging using onshore dense seismic arrays located at regional distances on the order of 1000 km, which provides faster source images than conventional teleseismic back-projections. We implement this method in a simulated real-time environment, and analysed the 2011 Tohoku earthquake rupture with two clusters of Hi-net stations in Kyushu and Northern Hokkaido, and the 2014 Iquique event with the Earthscope USArray Transportable Array. The results yield reasonable estimates of rupture area, which is approximated by an ellipse and leads to the construction of simple slip models based on empirical scaling of the rupture area, seismic moment and average slip. The slip model is then used as the input of the tsunami simulation package COMCOT to predict the tsunami waves. In the example of the Tohoku event, the earthquake source model can be acquired within 6 minutes from the start of rupture and the simulation of tsunami waves takes less than 2 min, which could facilitate a timely tsunami warning. The predicted arrival time and wave amplitude reasonably fit observations. Based on this method, we propose to develop an automatic warning mechanism that provides rapid near-field warning for areas of high tsunami risk. The initial focus will be Japan, Pacific Northwest and Alaska, where dense seismic networks with the capability of real-time data telemetry and open data accessibility, such as the Japanese HiNet (>800

    Dudrick, Stanley J

    2003-01-01

    This article recounts the conditions and status of surgical nutrition support in the 1960s and the antecedent basic and clinical investigational work leading to the development of a practical and efficacious method of adequate nourishment entirely by vein in Beagle puppies; describes the subsequent clinical application of the knowledge, techniques, and technology to the first successful long-term total parenteral nutrition (TPN) support of critically ill pediatric and adult patients; and admonishes nutritionists of all backgrounds that some need for parenteral nutrition will likely always exist and that it is incumbent upon everyone to continue endeavors to advance the germinal methodology to perfection. The relevant indications, limitations, hindrances, motivational factors, and studies regarding the development of TPN are reviewed, and the fundamental investigational work culminating in the first successful growth and development of Beagle puppies and a human infant fed entirely by vein are described firsthand. The details of the orderly and logical scientific development of the principles and components of the techniques in animals, infants, and adults are related. Knowledge, techniques, and technologic constituents of the first successful long-term TPN system were developed in the basic biochemical and animal laboratories initially in 6 puppies and subsequently adapted clinically for the efficacious long-term i.v. support of 6 critically ill surgical adult patients and a newborn infant before its widespread clinical application. Long-term TPN was inaugurated successfully as a safe and effective i.v. feeding technique nearly 4 decades ago. However, basic and clinical investigations must continue to be encouraged, supported, and carried out in the quest to perfect the current rudimentary technology, methodology, and outcomes.

    Fuel Cells are often considered in the market place as just power providers. Whilst fuel cells do provide power, there are additional beneficial characteristics that should be highlighted to consumers. Due to the high price premiums associated with fuel cells, added value features need to be exploited in order to make them more appealing and increase unit sales and market penetration. This paper looks at the approach taken by two companies to sell high value fuel cells to niche markets. The first, SFC Energy, has a proven track record selling fuel cell power providers. The second, Bloom Energy, is making significant progress in the US by having sold its Energy Server to more than 40 corporations including Wal-Mart, Staples, Google, eBay and Apple. Further to these current markets, two prospective added value applications for fuel cells are discussed. These are fuel cells for aircraft APUs and fuel cells for fire prevention. These two existing markets and two future markets highlight that fuel cells are not just power providers. Rather, they can be used as solutions to many needs, thus being more cost effective by replacing a number of incumbent systems at the same time.

    To examine the neurologic cinematographic contributions of Gheorghe Marinescu. Near the end of the 19th century, cinematography developed and was immediately recognized as a new technique applicable to medical documentation. After studying with several prominent European neurologists and deeply influenced by Jean-Martin Charcot, Marinescu returned to Bucharest in 1897 and applied moving picture techniques to the study of neurologic patients. The Romanian State Archives were researched for original Marinescu films, and related publications were translated from Romanian and French. Between 1899 and 1902, Marinescu perfected the use of cinematography as a research method in neurosciences and published five articles based on cinematographic documents. He focused his studies particularly on organic gait disorders, locomotor ataxia, and hysteria. He adapted Charcot's method of lining up several patients with the same disorder and showing them together to permit appreciation of archetypes and formes frustes. He decomposed the moving pictures into sequential tracings for publication. He documented treatment results with cases filmed before and after therapy. Processed and digitized excerpts of these films accompany this manuscript. Marinescu's cinematographic studies led to several original contributions in clinical neurology. Remaining film archives include examples of many neurologic diseases, his examination techniques, and the working medical environment of the young founder of the Romanian school of neurology.

  10. Study of Early Transition Metal Carbides for Energy Storage Applications

    NASA Astrophysics Data System (ADS)

    Dall'Agnese, Yohan

    An increase in energy and power density is needed to match the growing energy storage demands linked with the development of renewable energy production, and portable electronics. Several energy storage technologies exist including lithium-ion batteries, sodium-ion batteries, fuel cells and supercapacitors. These systems are mutually complementary. For example, supercapacitors can deliver high power densities whereas batteries can be used for high energy density applications. The first objective of this work was to investigate the electrochemical performances of a new family of 2-D materials called MXenes by cyclic voltammetry and galvanostatic charge-discharge measurements and to propose new solutions to tackle the energy storage concern. To achieve this goal, several directions have been explored. The first part of the research focused on Ti3C 2-based MXenes behavior as electrode materials for supercapacitors in aqueous electrolytes. The charge storage mechanisms in basic and neutral aqueous electrolytes, investigated by X-ray diffraction, were demonstrated to be attributed to cations intercalation between Ti3C2 layers. X-ray photoelectron spectroscopy highlighted the contribution of oxygenated functional groups on surface redox reactions in sulfuric acid. High capacitances were achieved, up to 520 F/cm3 and 325 F/g. Then the electrochemical behaviors of MXenes in sodium-based organic electrolytes were explored. A new hybrid system of sodium-ion capacitor was proposed. It was demonstrated that V2C-based MXene electrodes were suitable to be used as positive electrodes with an operating potential from 1 V to 3.5 V vs. Na+/Na. Continuous intercalation and de-intercalation of sodium ions between the V2C layers during sodiation and desodiation were showed by X-ray diffraction. An asymmetric sodium-ion capacitor full cell was assembled using hard carbon as negative electrode and showed promising results, with a capacity of 50 mAh/g. The last part was focused on the

    Delays in arteriovenous fistula maturation can cause care delays and increased costs. Increased distention pressure and intermittent wall shear stress may dilate veins based on prior research. Early use of non-invasive devices may help assist clinical arteriovenous fistula dilation. This was an Institutional Review Board approved study. After arteriovenous fistula creation, a novel, intermittent pneumatic compression device (Fist Assist ® ) was applied 15 cm proximal to arteriovenous fistula enabling 60 mmHg of cyclic compression for 6 h daily for 30 days. Among the patients who completed 1 month follow-up, 30 (n = 30) arteriovenous fistula patients were in the study arm to test vein dilation with Fist Assist. Controls (n = 16) used a sham device. Vein size was measured and recorded at baseline and after 30 days by duplex measurement. Clinical results (percentage increase) were recorded and tested for significance. No patients experienced thrombosis or adverse effects. Patient compliance and satisfaction was high. After 1 month, the mean percentage increase in vein diameter in the Fist Assist treatment group was significantly larger (p = 0.026) than controls in the first 5 mm segment of the fistula after the anastomosis. All fistulas treated with Fist Assist are still functional with no reported thrombosis or extravasations. Early application of an intermittent pneumatic compression device may assist in arteriovenous fistula dilation and are safe. Non-invasive devices like Fist Assist may have clinical utility to help fistulae development and decrease costs as they may eventually assist maturation.

    2017-07-01

    Microfocus CT (micro-CT) has traditionally been used in industry and preclinical studies, although it may find new applicability in the routine clinical setting. It can provide high-resolution three-dimensional digital imaging data sets to the same level of detail as microscopic examination without the need for tissue dissection. Micro-CT is already enabling non-invasive detailed internal assessment of various tissue specimens, particularly in breast imaging and early gestational fetal autopsy, not previously possible from more conventional modalities such as MRI or CT. In this review, we discuss the technical aspects behind micro-CT image acquisition, how early work with small animal studies have informed our knowledge of human disease and the imaging performed so far on human tissue specimens. We conclude with potential future clinical applications of this novel and emerging technique.

    Heart Disease affects approximately 70 million people worldwide where most people do not even know the symptoms. This research examines the prototype of early warning system for heart disease by android application. It aims to facilitate users to early detect heart disease which can be used independently. To build the application in android phone, variable centered intelligence rule system (VCIRS) as decision makers and pulse sensor - Arduino as heart rate detector were applied in this study. Moreover, in Arduino, the heart rate will become an input for symptoms in Android Application. The output of this system is the conclusion statement of users diagnosed with either coronary heart disease, hypertension heart disease, rheumatic heart disease or do not get any kind of heart disease. The result of diagnosis followed by analysis of the value of usage variable rate (VUR) rule usage rate (RUR) and node usage rate (NUR) that shows the value of the rule that will increase when the symptoms frequently appear. This application was compared with the medical analysis from 35 cases of heart disease and it showed concordance between diagnosis from android application and expert diagnosis of the doctors.

    Especial skills are skills that are distinctive by virtue of massive practice within the narrow contexts in which they are expressed. In the first demonstration of especial skills, Keetch, Schmidt, Lee, and Young (2005) showed that experienced basketball players are better at shooting baskets from the foul line, where they had massive amounts of practice, than would expected from their success at other locations closer to or farther from the basket. Similar results were obtained for baseball throwing. The authors asked whether especial skills hold in archery, a sport requiring less movement. If the emergence of especial skills depends on large-scale movement, one would expect archery to escape so-called especialism. But if the emergence of especial skills reflects a more general tendency for highly specific learning, experienced archers should show especial skills. The authors obtained evidence consistent with the latter prediction. The expert archers did much better at their most highly practiced distance than would be expected by looking at the overall function relating shooting score to distance. We offer a mathematical model to account for this result. The findings attest to the generality of the especial skills phenomenon.

    Attention to internal body sensations is practiced in most meditation traditions. Many traditions state that this practice results in increased awareness of internal body sensations, but scientific studies evaluating this claim are lacking. We predicted that experienced meditators would display performance superior to that of nonmeditators on heartbeat detection, a standard noninvasive measure of resting interoceptive awareness. We compared two groups of meditators (Tibetan Buddhist and Kundalini) to an age- and body mass index-matched group of nonmeditators. Contrary to our prediction, we found no evidence that meditators were superior to nonmeditators in the heartbeat detection task, across several sessions and respiratory modulation conditions. Compared to nonmeditators, however, meditators consistently rated their interoceptive performance as superior and the difficulty of the task as easier. These results provide evidence against the notion that practicing attention to internal body sensations, a core feature of meditation, enhances the ability to sense the heartbeat at rest.

  6. a Structure of Experienced Time

    NASA Astrophysics Data System (ADS)

    Havel, Ivan M.

    2005-10-01

    The subjective experience of time will be taken as a primary motivation for an alternative, essentially discontinuous conception of time. Two types of such experience will be discussed, one based on personal episodic memory, the other on the theoretical fine texture of experienced time below the threshold of phenomenal awareness. The former case implies a discrete structure of temporal episodes on a large scale, while the latter case suggests endowing psychological time with a granular structure on a small scale, i.e. interpreting it as a semi-ordered flow of smeared (not point-like) subliminal time grains. Only on an intermediate temporal scale would the subjectively felt continuity and fluency of time emerge. Consequently, there is no locally smooth mapping of phenomenal time onto the real number continuum. Such a model has certain advantages; for instance, it avoids counterintuitive interpretations of some neuropsychological experiments (e.g. Libet's measurement) in which the temporal order of events is crucial.

    Ensuring the financial security of individuals recovering from first episode psychosis is imperative, but disability income programs can be powerful disincentives to employment, compromising the social and occupational aspects of recovery. Survival analysis and Cox regression analysis were used to examine the rate at which individuals served by early intervention for psychosis (EIP) services apply for government disability income benefits and factors that predict rate of application. Health records for 558 individuals served by EIP programs were reviewed. Within the first year of receiving services 30% will make application for disability income; 60% will do so by 5 years. Rate of application is predicted by rate of hospital admission, financial status and engagement in productivity roles at the time of entry to EIP service. The findings suggest the need to examine the extent to which the recovery goals of EI services are undermined by early application for government income support. They also suggest the need to develop best practice guidelines related to ensuring the economic security of individuals served.

    This study proposes a new simulation platform named Simulation Integrated Management (SIM) for the analysis of parallel and distributed systems. The platform eases the process of designing and testing both applications and architectures. The main characteristics of SIM are flexibility, scalability, and expandability. To improve the efficiency of project development, new models of early-warning satellite system were designed based on the SIM platform. Finally, through a series of experiments, the correctness of SIM platform and the aforementioned early-warning satellite models was validated, and the systematical analyses for the orbital determination precision of the ballistic missile during its entire flight process were presented, as well as the deviation of the launch/landing point. Furthermore, the causes of deviation and prevention methods will be fully explained. The simulation platform and the models will lay the foundations for further validations of autonomy technology in space attack-defense architecture research.

    In order to reduce the societal risk associated with natural hazards novel technologies could help to advance in early warning systems. In our study we evaluate the use of multi-sensor technologies as possible early-warning systems for landslides and man-made structures, and the integration of the information in a simple Decision Support System (DSS). In this project, particular attention will be paid to some new possibilities available in the field of distributed monitoring systems of relevant parameters for landslide and man-made structures monitoring (such as large dams and bridges), and among them the distributed monitoring of temperature, strain and acoustic signals by FO cables. Fiber Optic measurements are becoming more and more popular. Fiber optic cables have been developed in the telecommunication business to send large amounts of information over large distances with the speed of light. Because of the commercial application, production costs are relatively low. Using fiber optics for measurements has several advantages. This novel technology is, for instance, immune to electromagnetic interference, appears stable, very accurate, and has the potential to measure several independent physical properties in a distributed manner. The high resolution spatial and temporal distributed information on e.g. temperature or strain (or both) make fiber optics an interesting measurement technique. Several applications have been developed in both engineering as science and the possibilities seem numerous. We will present a thorough literature review that was done to assess the applicability and limitations of FO cable technology. This review was focused but not limited to application in landslide research. Several examples of current practices will be shown, also from outside the natural hazard practice and possible application will be discussed.

    To investigate the application of prospective space-time scan statistic in the early stage of detecting infectious disease outbreaks. The prospective space-time scan statistic was tested by mimicking daily prospective analyses of bacillary dysentery data of Chengdu city in 2005 (3212 cases in 102 towns and villages). And the results were compared with that of purely temporal scan statistic. The prospective space-time scan statistic could give specific messages both in spatial and temporal. The results of June indicated that the prospective space-time scan statistic could timely detect the outbreaks that started from the local site, and the early warning message was powerful (P = 0.007). When the merely temporal scan statistic for detecting the outbreak was sent two days later, and the signal was less powerful (P = 0.039). The prospective space-time scan statistic could make full use of the spatial and temporal information in infectious disease data and could timely and effectively detect the outbreaks that start from the local sites. The prospective space-time scan statistic could be an important tool for local and national CDC to set up early detection surveillance systems.

    We investigated the application of Alberta Infant Motor Scale (AIMS) in screening motor development delay in the follow-up of high-risk infants who were discharged from NICU, to explain the state of infants' motor development and propose early individualized intervention. The study design was a randomized, single-blind trial by selecting patients between April 2015 and November 2015 in our hospital, children nerve recovery branch clinics and 77 cases of high-risk infants. We randomly divided the patients into observation group (39 cases) and control group (38 cases). To evaluate the application with AIMS, observation group was based on evaluation results for the first time to give rehabilitation training plan making, early intervention, control group according to the growth and development milestone in order to guide parents to take family training interval of 3 months. While comparing the two groups of high-risk infants before the intervention, the months of age, gender, risk factors, it was found that the AIMS scores, each position AIMS scores did not show a significant difference in percentile (p>0.05). There was also no significant difference between two groups in the seat and stand AIMS scores before and after intervention (p>0.05). However, the comparison of two groups of high-risk infants after intervention in comparison showed that the observation group supine AIMS scores and AIMS scores were significantly higher than the control group (p<0.05). Prone position AIMS scores observation group was also significantly higher than that of the control group (p<0.01). The corresponding percentile for two groups after the intervention of AIMS scores was less than 10% of cases, which was significantly lower in the observation group (p<0.01). AIMS can predict the development delay in high-risk infants, for improving the early hypernymic diagnosis and intervention.

  13. Monitoring of unstable slopes by MEMS tilting sensors and its application to early warning

    2015-09-01

    The present paper addresses the newly developed early warning technology that can help mitigate the slope failure disasters during heavy rains. Many studies have been carried out in the recent times on early warning that is based on rainfall records. Although those rainfall criteria of slope failure tells the probability of disaster on a regional scale, it is difficult for them to judge the risk of particular slopes. This is because the rainfall intensity is spatially too variable to forecast and the early warning based on rainfall alone cannot take into account the effects of local geology, hydrology and topography that vary spatially as well. In this regard, the authors developed an alternative technology in which the slope displacement/deformation is monitored and early warning is issued when a new criterion is satisfied. The new MEMS-based sensor monitors the tilting angle of an instrument that is embedded at a very shallow depth and the record of the tilting angle corresponds to the lateral displacement at the slope surface. Thus, the rate of tilting angle that exceeds a new criterion value implies an imminent slope failure. This technology has been validated against several events of slope failures as well as against a field rainfall test. Those validations have made it possible to determine the criterion value of the rate of tilting angle to be 0.1 degree/hour. The advantage of the MEMS tilting sensor lies in its low cost. Hence, it is possible to install many low-cost sensors over a suspected slope in which the precise range of what is going to fall down during the next rainfall is unknown. In addition to the past validations, this paper also introduces a recent application to a failed slope in the Izu Oshima Island where a heavy rainfall-induced slope failure occurred in October, 2013.

    To explore the application of multiplex nested methylated specific polymerase chain reaction (PCR) in the early diagnosis of epithelial ovarian carcinoma (EOC). Serum and fresh tissue samples were collected from 114 EOC patients. RUNX3, TFPI2 and OPCML served as target genes. Methylation levels of tissues were assessed by multiplex nested methylated specific PCR, the results being compared with those for carcinoma antigen 125 (CA125). The serum free deoxyribose nucleic acid (DNA) methylation spectrum of EOC patients was completely contained in the DNA spectrum of cancer tissues, providing an accurate reflection of tumor DNA methylation conditions. Serum levels of CA125 and free DNA methylation in the EOC group were evidently higher than those in benign lesion and control groups (p<0.05). Patients with early EOC had markedly lower serum CA125 than those with advanced EOC (p<0.05), but there was no significant difference in free DNA methylation (p>0.05). The sensitivity, specificity and positive predicative value (PPV) of multiplex nested methylated specific PCR were significantly higher for detection of all patients and those with early EOC than those for CA125 (p<0.05). In the detection of patients with advanced EOC, the PPV of CA125 detection was obviously lower than that of multiplex nested methylated specific PCR (p>0.05), but there was no significant difference in sensitivity (p>0.05). Serum free DNA methylation can be used as a biological marker for EOC and multiplex nested methylated specific PCR should be considered for early diagnosis since it can accurately determine tumor methylation conditions.

    The role of the basal ganglia, and more specifically of the striatum, in language is still debated. Recent studies have proposed that linguistic abilities involve two distinct types of processes: the retrieving of stored information, implicating temporal lobe areas, and the application of combinatorial rules, implicating fronto-striatal circuits. Studies of patients with focal lesions and neurodegenerative diseases have suggested a role for the striatum in morphological rule application, but functional imaging studies found that the left caudate was involved in syntactic processing and not morphological processing. In the present study, we tested the view that the basal ganglia are involved in rule application and not in lexical retrieving in a model of striatal dysfunction, namely Huntington's disease at early stages. We assessed the rule-lexicon dichotomy in the linguistic domain with morphology (conjugation of non-verbs and verbs) and syntax (sentence comprehension) and in a non-linguistic domain with arithmetic operations (subtraction and multiplication). Thirty Huntington's disease patients (15 at stage I and 15 at stage II) and 20 controls matched for their age and cultural level were included in this study. Huntington's disease patients were also assessed using the Unified Huntington's Disease Rating Scale (UHDRS) and MRI. We found that early Huntington's disease patients were impaired in rule application in the linguistic and non-linguistic domains (morphology, syntax and subtraction), whereas they were broadly spared with lexical processing. The pattern of performance was similar in patients at stage I and stage II, except that stage II patients were more impaired in all tasks assessing rules and had in addition a very slight impairment in the lexical condition of conjugation. Finally, syntactic rule abilities correlated with all markers of the disease evolution including bicaudate ratio and performance in executive function, whereas there was no

    Improvement of the interaction between forensic mental health nurses and patients may lead to a reduction of inpatient violence. The concept under study is detached concern, which refers to nurses' skills to neutralize the emotional appeal of patients by a balanced attitude between objectivity and emotional involvement. The Patient Contact Questionnaire (PCQ) aims at measuring the degree of concern of nurses for their patients. The PCQ was applied in a pretest-posttest design, evaluating the effects of the Early Recognition Method (ERM). This method aims at the prevention of inpatient violence in forensic psychiatry. Subjects were 116 forensic mental heath nurses working on 16 wards of a large Dutch forensic hospital. First, the baseline scores were compared to scores reported in an earlier study conducted in general psychiatry. Second, pretest-posttest comparisons were carried out for all nurses, and for subgroups of nurses with regard to gender, educational level, years of working experience, and patient population. Third, pretest-posttest comparisons were made on the PCQ item level. The baseline scores of male nurses indicated significantly higher levels of concern than those of female nurses. In addition, more experienced nurses scored significantly higher with regard to concern than less experienced nurses. When comparing the scores before and after applying ERM, no significant differences were found. However, the sores of female nurses showed a tendency toward more concern after implementation of ERM. Detached concern may be a meaningful concept in forensic mental health nursing in measuring nurses' concern for their patients. Levels of detached concern did not change significantly after application of ERM. However, the application of the PCQ could contribute to a better understanding of the interaction between nurses and their patients. 2010 Elsevier Inc. All rights reserved.

    ischemia demonstrated a decreasing failure rate, suggesting the predominance of early failures (β = 0.7395, θ = 6.8, mean time to failure = 8.2, index of fit = 0.99391, R(2) = 0.98786). By 3.1 months, 10% of interventions failed. This point (90% reliability) was identified as the basic rating life. Using multivariate analysis of failure data, independent predictors of early failure (before 3.1 months) included tissue loss, long lesion length, chronic total occlusions, heart failure, and end-stage renal disease. Application of a RE framework to the assessment of clinical outcomes after peripheral interventions is feasible, and potentially more informative than traditional techniques. Conceptualization of interventions as "products" permits application of product life-cycle models that allow for empiric definition of "early failure" may facilitate comparative effectiveness analysis and enable the development of individualized surveillance programs after endovascular interventions.

    2015-02-01

    This article describes the development and early application of the Scottish Community Nursing Workload Measurement Tool, part of a suite of tools aiming to ensure a consistent approach to measuring nursing workload across NHS Scotland. The tool, which enables community nurses to record and report their actual workload by collecting information on six categories of activity, is now being used by all NHS boards as part of a triangulated approach. Data being generated by the tool at national level include indications that approximately 50% of band 6 district nurses' time is spent in face-to-face and non-face-to-face contact and planned sessions with patients, and that over 60% of face-to-face contacts are at 'moderate' and 'complex' levels of intervention (2012 data). These data are providing hard evidence of key elements of community nursing activity and practice that will enable informed decisions about workforce planning to be taken forward locally and nationally. The article features an account of the early impact of the tool's implementation in an NHS board by an associate director of nursing. Positive effects from implementation include the generation of reliable data to inform planning decisions, identification of issues around nursing time spent on administrative tasks, clarification of school nursing roles, and information being fed back to teams on various aspects of performance.

    Cancer is account for 13% of all deaths around the world and is the third cause of mortality in Iran. More than one third of these cases are pre-ventable and about 33% are curable with early detection. The aim of this study was to determine the predictors of cancer early detection (CED) behaviors applying Protection Motivation Theory (PMT). In this cross-sectional study, cluster sampling method was employed to recruit 260 individuals of above 20 years old in Yazd, Iran and a researcher designed questionnaire was completed through interviews for each of the respondents. PMT theoretical variables and CED behaviors were the basis of data collection procedure. Participants acquired 64.47% of the protection motivation, 30.97% of the passive and 45.64% of the active behaviors‟ possible scores. Theory constructs predicted 19.8%, 15.6% and 9.6% of the variations for protection motivation, passive and active behavior respectively. Protection motivation was responsible for 3.6% of passive and 8% of active behaviors‟ variations. Considering the scarceness of CED behaviors and the applicability of PMT in predicting these behaviors, utilization of the PMT‟s constructs in any interventional programs to accelerate CED behaviors could be an alternate methodological choice in the cancer control initiatives.

    The paper will review the feasibility of adapting the Modified Transient Plane Source (MTPS) method as a screening tool for early-detection of explosives and hazardous materials. Materials can be distinguished from others based on their inherent thermal properties (e.g. thermal effusivity) in testing through different types of barrier materials. A complimentary advantage to this technique relative to other traditional detection technologies is that it can penetrate reflective barrier materials, such as aluminum, easily. A strong proof-of-principle is presented on application of the MTPS transient thermal property measuring in the early-screening of liquid explosives. The work demonstrates a significant sensitivity to distinguishing a wide range of fluids based on their thermal properties through a barrier material. The work covers various complicating factors to the longer-term adoption of such a method including the impact of carbonization and viscosity. While some technical challenges remain, the technique offers significant advantages in complimenting existing detection methods in being able to penetrate reflective metal containers (e.g. aluminum soft drinkscans) with ease.

    The application of biomolecular magnetic resonance imaging becomes increasingly important in the context of early cartilage changes in degenerative and inflammatory joint disease before gross morphological changes become apparent. In this limited technical report, we investigate the correlation of MRI T1, T2 and T1ρ relaxation times with quantitative biochemical measurements of proteoglycan and collagen contents of cartilage in close synopsis with histologic morphology. A recently developed MRI sequence, T1ρ, was able to detect early intracartilaginous degeneration quantitatively and also qualitatively by color mapping demonstrating a higher sensitivity than standard T2-weighted sequences. The results correlated highly with reduced proteoglycan content and disrupted collagen architecture as measured by biochemistry and histology. The findings lend support to a clinical implementation that allows rapid visual capturing of pathology on a local, millimeter level. Further information about articular cartilage quality otherwise not detectable in vivo, via normal inspection, is needed for orthopedic treatment decisions in the present and future.

    The Boxing Day Tsunami of 2004 killed over 240,000 people in 14 countries and inundated the affected shorelines with waves reaching heights up to 30m. This natural disaster coincided with an information catastrophy, as potentially life-saving early warning information existed, yet no means were available to deliver it to the communities under imminent threat. Tsunami Early Warning Capabilities have improved in the meantime by continuing development of modular Tsunami Early Warning Systems (TEWS). However, recent tsunami events, like the Chile 2010 and the Tohoku 2011 tsunami demonstrate that the key challenge for ongoing TEWS research on the supranational scale still lies in the timely issuing of reliable early warning messages. Since 2004, the GFZ German Research Centre for Geosciences has built up expertise in the field of TEWS. Within GFZ, the Centre for GeoInformation Technology (CEGIT) has focused its work on the geoinformatics aspects of TEWS in two projects already: The German Indonesian Tsunami Early Warning System (GITEWS) funded by the German Federal Ministry of Education and Research (BMBF) and the Distant Early Warning System (DEWS), a European project funded under the sixth Framework Programme (FP6). These developments are continued in the TRIDEC project (Collaborative, Complex, and Critical Decision Processes in Evolving Crises) funded under the European Union's seventh Framework Programme (FP7). This ongoing project focuses on real-time intelligent information management in Earth management and its long-term application. All TRIDEC developments are based on Free and Open Source Software (FOSS) components and industry standards where-ever possible. Tsunami Early Warning in TRIDEC is also based on mature system architecture models to ensure long-term usability and the flexibility to adapt to future generations of Tsunami sensors. All open source software produced by the project consortium are foreseen to be published on FOSSLAB, a publicly available

  5. Future of Earthquake Early Warning: Quantifying Uncertainty and Making Fast Automated Decisions for Applications

    NASA Astrophysics Data System (ADS)

    Wu, Stephen

    Earthquake early warning (EEW) systems have been rapidly developing over the past decade. Japan Meteorological Agency (JMA) has an EEW system that was operating during the 2011 M9 Tohoku earthquake in Japan, and this increased the awareness of EEW systems around the world. While longer-time earthquake prediction still faces many challenges to be practical, the availability of shorter-time EEW opens up a new door for earthquake loss mitigation. After an earthquake fault begins rupturing, an EEW system utilizes the first few seconds of recorded seismic waveform data to quickly predict the hypocenter location, magnitude, origin time and the expected shaking intensity level around the region. This early warning information is broadcast to different sites before the strong shaking arrives. The warning lead time of such a system is short, typically a few seconds to a minute or so, and the information is uncertain. These factors limit human intervention to activate mitigation actions and this must be addressed for engineering applications of EEW. This study applies a Bayesian probabilistic approach along with machine learning techniques and decision theories from economics to improve different aspects of EEW operation, including extending it to engineering applications. Existing EEW systems are often based on a deterministic approach. Often, they assume that only a single event occurs within a short period of time, which led to many false alarms after the Tohoku earthquake in Japan. This study develops a probability-based EEW algorithm based on an existing deterministic model to extend the EEW system to the case of concurrent events, which are often observed during the aftershock sequence after a large earthquake. To overcome the challenge of uncertain information and short lead time of EEW, this study also develops an earthquake probability-based automated decision-making (ePAD) framework to make robust decision for EEW mitigation applications.

    Translating prognostic and diagnostic biomarker candidates into clinical applications takes time, is very costly, and many candidates fail. It is therefore crucial to be able to select those biomarker candidates that have the highest chance of successfully being adopted in the clinic. This requires an early estimate of the potential clinical impact and commercial value. In this paper, we aim to demonstratively evaluate a set of novel biomarkers in terms of clinical impact and commercial value, using occurrence of cardiovascular disease (CVD) in type-2 diabetes (DM2) patients as a case study. We defined a clinical application for the novel biomarkers, and subsequently used data from a large cohort study in The Netherlands in a modeling exercise to assess the potential clinical impact and headroom for the biomarkers. The most likely application of the biomarkers would be to identify DM2 patients with a low CVD risk and subsequently withhold statin treatment. As a result, one additional CVD event in every 75 patients may be expected. The expected downstream savings resulted in a headroom for a point-of-care device ranging from €119.09 at a willingness to accept of €0 for one additional CVD event, to €0 at a willingness to accept of €15,614 or more. It is feasible to evaluate novel biomarkers on outcomes directly relevant to technological development and clinical adoption. Importantly, this may be attained at the same point in time and using the same data as used for the evaluation of association with disease and predictive power.

    This article describes the development of the smartphone application for cognitive-behavioural case management of young individuals with early psychosis and examines the acceptance and potential clinical benefits of this application through a pilot survey. Gwangju Bukgu-Community Mental Health Center developed and launched a smartphone application (Heal Your Mind [HYM]) for cognitive-behavioural case management and symptom monitoring. The HYM application for clients includes 6 main modules including thought record, symptom record, daily life record, official notices, communication and scales. The key module is the "thought record" for self-directed cognitive-behavioural treatment. When the client writes and sends the self-cognitive-behavioural therapy sheet to the case manager, the latter receives a notification and can provide feedback in real time. We conducted a survey to investigate the acceptance and feasibility of this approach among young clients with early psychosis. A total of 24 clients with early psychosis participated in this survey. More than 80% of participants reported that it was easy to learn to use this application, and no one described this application as very complicated or reported that they needed a long time to learn how to use it. About 80% of participants were satisfied with this application, and 70% reported that they received help as a result of using this application. This study suggests that this smartphone application is useful for young individuals with early psychosis and that it may contribute to the development of both young customer- and case manager-friendly systems for this clinical population. © 2017 John Wiley & Sons Australia, Ltd.

    Rapid assessment of drought impacts can aid water managers in assessing mitigation options, and guide decision making with respect to requests for local water transfers, county drought disaster designations, or state emergency proclamations. Satellite remote sensing offers an efficient way to provide quantitative assessments of drought impacts on agricultural production and land fallowing associated with reductions in water supply. A key advantage of satellite-based assessments is that they can provide a measure of land fallowing that is consistent across both space and time. Here we describe an approach for monthly mapping of land fallowing developed as part of a joint effort by USGS, USDA, and NASA to provide timely assessments of land fallowing during drought events. This effort has used the Central Valley of California as a pilot region for development and testing of an operational approach. To provide quantitative measures of fallowed land from satellite data early in the season, we developed a decision tree algorithm and applied it to timeseries of normalized difference vegetation index (NDVI) data from Landsat TM, ETM+, and MODIS. Our effort has been focused on development of leading indicators of drought impacts in the March - June timeframe based on measures of crop development patterns relative to a reference period with average or above average rainfall. This capability complements ongoing work by USDA to produce and publicly release within-season estimates of fallowed acreage from the USDA Cropland Data Layer. To assess the accuracy of the algorithms, monthly ground validation surveys were conducted along transects across the Central Valley at more than 200 fields per month from March - June, 2013. Here we present the algorithm for mapping fallowed acreage early in the season along with results from the accuracy assessment, and discuss potential applications to other regions.

Focus was given to the use of RFID tags and its effects on technology and CRM through a case study on VeriChip, the only corporation to hold the rights and the patent to the implantable chip for humans, and an empirically based study on working professionals to measure perceptions by early adopters of such technology. Through hypotheses-testing procedures, it was found that although some resistance to accept microchip implants was found in several applications, especially among gender, it was totally expected that healthcare and medical record keeping activities would be universally treated in a positive light and the use of authorities (namely governmental agencies) would be equally treated in a negative light by both sexes. Future trends and recommendations are presented along with statistical results collected through personal interviews.

    The activities of debris flow (DF) in the Wenchuan earthquake-affected area significantly increased after the earthquake on 12 May 2008. The safety of the lives and property of local people is threatened by DFs. A physics-based early warning system (EWS) for DF forecasting was developed and applied in this earthquake area. This paper introduces an application of the system in the Wenchuan earthquake-affected area and analyzes the prediction results via a comparison to the DF events triggered by the strong rainfall events reported by the local government. The prediction accuracy and efficiency was first compared with a contribution-factor-based system currently used by the weather bureau of Sichuan province. The storm on 17 August 2012 was used as a case study for this comparison. The comparison shows that the false negative rate and false positive rate of the new system is, respectively, 19 and 21 % lower than the system based on the contribution factors. Consequently, the prediction accuracy is obviously higher than the system based on the contribution factors with a higher operational efficiency. On the invitation of the weather bureau of Sichuan province, the authors upgraded their prediction system of DF by using this new system before the monsoon of Wenchuan earthquake-affected area in 2013. Two prediction cases on 9 July 2013 and 10 July 2014 were chosen to further demonstrate that the new EWS has high stability, efficiency, and prediction accuracy.

    Early detection of malignant tumours, or their precursor lesions, can dramatically improve patient outcome. High risk human Papillomavirus (HPV), particularly HPV16, infection can lead to the initiation and development of uterine cervical neoplasia. Bearing this in mind the identification of the effects of HPV infection may have clinical value. In this manuscript we investigate the application of Raman microspectroscopy to detect the presence of HPV in cultured cells when compared with normal cells. We also investigate the effect of sample fixation, which is a common clinical practice, on the ability of Raman spectroscopy to detect the presence of HPV. Raman spectra were acquired from Primary Human Keratinocytes (PHK), PHK expressing the E7 gene of HPV 16 (PHK E7) and CaSki cells, an HPV16 containing cervical carcinoma derived cell line. The average Raman spectra display variations, mostly in peaks relating to DNA and proteins, consistent with HPV gene expression and the onset of neoplasia in both live and fixed samples. Principle component analysis was used to objectively discriminate between the cells types giving sensitivities up to 100% for the comparison between PHK and CaSki. These results show that Raman spectroscopy can discriminate between cell lines representing different stages of cervical neoplasia. Furthermore Raman spectroscopy was able to identify cells expressing the HPV 16 E7 gene suggesting the approach may be of value in clinical practice. Finally this technique was also able to detect the effects of the virus in fixed samples demonstrating the compatibility of this technique with current cervical screening methods. However if Raman spectroscopy is to make a significant impact in clinical practice the long acquisition times must be addressed. In this report we examine the potential for beam shaping and advanced to improve the signal to noise ration hence subsequently facilitating a reduction in acquisition time.

  18. Assessment of critical minerals: Updated application of an early-warning screening methodology

    McCullough, Erin A.; Nassar, Nedal

    2017-01-01

    Increasing reliance on non-renewable mineral resources reinforces the need for identifying potential supply constraints before they occur. The US National Science and Technology Council recently released a report that outlines a methodology for screening potentially critical minerals based on three indicators: supply risk (R), production growth (G), and market dynamics (M). This early-warning screening was initially applied to 78 minerals across the years 1996 to 2013 and identified a subset of minerals as “potentially critical” based on the geometric average of these indicators—designated as criticality potential (C). In this study, the screening methodology has been updated to include data for 2014, as well as to incorporate revisions and modifications to the data, where applicable. Overall, C declined in 2014 for the majority of minerals examined largely due to decreases in production concentration and price volatility. However, the results vary considerably across minerals, with some minerals, such as gallium, recording increases for all three indicators. In addition to assessing magnitudinal changes, this analysis also examines the significance of the change relative to historical variation for each mineral. For example, although mined nickel’s R declined modestly in 2014 in comparison to that of other minerals, it was by far the largest annual change recorded for mined nickel across all years examined and is attributable to Indonesia’s ban on the export of unprocessed minerals. Based on the 2014 results, 20 minerals with the highest C values have been identified for further study including the rare earths, gallium, germanium, rhodium, tantalum, and tungsten.

    2014-03-01

    We developed an index of early life history diversity (ELHD) for Pacific salmon (Oncorhynchus spp.) Early life history diversity is the variation in morphological and behavioral traits expressed within and among populations by individual juvenile salmon during their downstream migration. A standard quantitative method does not exist for this prominent concept in salmon biology.

    Critical transitions between alternative stable states have been shown to occur across an array of complex systems. While our ability to identify abrupt regime shifts in natural ecosystems has improved, detection of potential early-warning signals previous to such shifts is still very limited. Using real monitoring data of a key ecosystem component, we here apply multiple early-warning indicators in order to assess their ability to forewarn a major ecosystem regime shift in the Central Baltic Sea. We show that some indicators and methods can result in clear early-warning signals, while other methods may have limited utility in ecosystem-based management as they show no or weak potential for early-warning. We therefore propose a multiple method approach for early detection of ecosystem regime shifts in monitoring data that may be useful in informing timely management actions in the face of ecosystem change.

    Allogeneic hematopoietic SCT (allo-HSCT) is a curative treatment for aggressive adult T-cell leukemia/lymphoma (ATLL). Considering the dismal prognosis associated with conventional chemotherapies, early application of allo-HSCT might be beneficial for patients with ATLL. However, no previous study has addressed the optimal timing of allo-HSCT from related donors. Hence, to evaluate the impact of timing of allo-HSCT for patients with ATLL, we retrospectively analyzed data from patients with ATLL who received an allo-HSCT from a related donor. The median age was 52 years. Patients were grouped according to the interval from diagnosis to allo-HSCT: early transplant group, <100 days, n=72; late transplant group, ⩾100 days, n=428. The corresponding constituents of disease status were not statistically different between the two groups (P=0.11). The probability of OS in the early transplant group was significantly higher than that in the late transplant group (4-year OS, 49.3% vs 31.2%). Multivariate analysis revealed that late allo-HSCT was an unfavorable prognostic factor for OS (hazard ratio, 1.46; 95% confidence interval (CI), 1.01-2.11; P=0.04). Despite the limitations of a retrospective study, it might be acceptable to consider early application of allo-HSCT for ATLL.

    Satellite data provide global observations of many of the earths system processes and features. These data are valuable for developing scientific products that increase our understanding of how the earths systems are integrated. The water, energy and carbon cycle exchanges between the land and atmosphere are linked by soil moisture. NASAs Soil Moisture Active Passive (SMAP) mission provides soil moisture and freeze thaw measurements from space and allows scientists to link the water energy and carbon cycles. In order for SMAP data to be best integrated into decision support systems, the mission has engaged with the stakeholder community since 2009 and has attempted to scale the utility of the data to the thematic societal impacts of the satellite product applications. The SMAP Mission, which launched on January 31, 2015, has actively grown an Early Adopter (EA) community as part of its applications effort and worked with these EAs to demonstrate a scaled thematic impact of SMAP data product in societally relevant decision support applications. The SMAP mission provides global observations of the Earths surface soil moisture, providing high accuracy, resolution and continuous global coverage. Through the Early Adopters Program, the SMAP Applications Team will spend the next 2 years after launch documenting and evaluating the use of SMAP science products in applications related to weather forecasting, drought, agriculture productivity, floods, human health and national security.

    To compare the use of mental representations (heuristics) in diagnostic reasoning of expert (> or = 5 years' experience) and novice (< 5 years' experience) emergency nurses. Clinical simulations were completed by a nationwide randomly selected sample of 173 experienced and 46 less-experienced emergency nurses (N = 219). Experienced nurses used the heuristic, Judging by Causal Systems (diagnostic inferences deduced from systems of causal factors) significantly more did than less-experienced nurses. Standardized nursing diagnoses may cut short the time needed to develop representational thinking and spare cognitive reserves for reasoning needed for complex patients. Faculty need to promote student's cognitive development through strategies that promote active, reflective, and integrative learning.

    To study the short-term response and tolerance of different doses of amino acids in parenteral nutrition among preterm infants. This study included 86 preterm infants who had a birth weight between 1 000 to 2 000 g and were admitted to the hospital within 24 hours of birth between March 2013 and June 2014. According to the early application of different doses of amino acids, they were randomized into low-dose group (n=29, 1.0 g/kg per day with an increase of 1.0 g/kg daily and a maximum of 3.5 g/kg per day), medium-dose group (n=28, 2.0 g/kg per day with an increase of 1.0 g/kg daily and a maximum of 3.7 g/kg per day), and high-dose group (n=29, 3.0 g/kg per day with an increase of 0.5-1.0 g/kg daily and a maximum of 4.0 g/kg per day). Other routine parenteral nutrition and enteral nutrition support were also applied. The maximum weight loss was lower and the growth rate of head circumference was greater in the high-dose group than in the low-dose group (P<0.05). The infants in the medium- and high-dose groups had faster recovery of birth weight, earlier attainment of 100 kcal/(kg·d) of enteral nutrition, shorter duration of hospital stay, and less hospital cost than those in the low-dose group (P<0.05). Blood urea nitrogen (BUN) levels in the high-dose group increased compared with the other two groups 7 days after birth (P<0.05). The levels of creatinine, pH, bicarbonate, bilirubin, and transaminase and the incidence of complications showed no significant differences between groups (P>0.05). Parenteral administration of high-dose amino acids in preterm infants within 24 hours after birth can improve the short-term nutritional status of preterm infants, but there is a transient increase in BUN level.

    Poor seed germination and early seedling growth associated with urea-induced soil ammonia volatilization are major constraints in the adoption of dry direct-seeded rice. To directly examine soil ammonia volatilization and its damage to seed germination and early seedling growth of dry direct-seeded rice when urea is applied at seeding, two Petri-dish incubation experiments and a field experiment were conducted. Ammonia volatilization due to urea application significantly reduced seed germination and early seedling growth of dry direct-seedling rice. NBPT significantly reduced ammonia volatilization following urea application. The application of ammonium sulfate, instead of urea at seeding, may mitigate poor crop establishment of dry direct-seeded rice. Root growth of dry direct-seeded rice was more seriously inhibited by soil ammonia volatilization than that of shoot. Results suggest that roots are more sensitive to soil ammonia toxicity than shoots in dry direct-seeded rice system when N is applied as urea at seeding. PMID:22454611

  18. The role of empathy in experiencing vicarious anxiety.

    Shu, Jocelyn; Hassell, Samuel; Weber, Jochen; Ochsner, Kevin N; Mobbs, Dean

    2017-08-01

    With depictions of others facing threats common in the media, the experience of vicarious anxiety may be prevalent in the general population. However, the phenomenon of vicarious anxiety-the experience of anxiety in response to observing others expressing anxiety-and the interpersonal mechanisms underlying it have not been fully investigated in prior research. In 4 studies, we investigate the role of empathy in experiencing vicarious anxiety, using film clips depicting target victims facing threats. In Studies 1 and 2, trait emotional empathy was associated with greater self-reported anxiety when observing target victims, and with perceiving greater anxiety to be experienced by the targets. Study 3 extended these findings by demonstrating that trait empathic concern-the tendency to feel concern and compassion for others-was associated with experiencing vicarious anxiety, whereas trait personal distress-the tendency to experience distress in stressful situations-was not. Study 4 manipulated state empathy to establish a causal relationship between empathy and experience of vicarious anxiety. Participants who took an empathic perspective when observing target victims, as compared to those who took an objective perspective using reappraisal-based strategies, reported experiencing greater anxiety, risk-aversion, and sleep disruption the following night. These results highlight the impact of one's social environment on experiencing anxiety, particularly for those who are highly empathic. In addition, these findings have implications for extending basic models of anxiety to incorporate interpersonal processes, understanding the role of empathy in social learning, and potential applications for therapeutic contexts.

  20. Experiencing authenticity - the core of student learning in clinical practice.

    PubMed

    Manninen, Katri

    2016-10-01

    Learning in clinical practice is challenging regarding organizational and pedagogical issues. Clinical education wards are one way to meet these challenges by focusing on both patient care and student learning. However, more knowledge is needed about how students' learning can be enhanced and about patients' and supervisors' roles in these settings. The aim was to explore nursing students' learning on a clinical education ward with an explicit pedagogical framework. Semi-structured interviews of students were analyzed using qualitative content analysis and an ethnographic study including observations and follow-up interviews of students, patients and supervisors was conducted. The core of student meaningful learning experiences both external and internal authenticity. Students in early stages immediately created mutual relationships, experienced both external and internal authenticity, and patients became active participants in student learning. Without a mutual relationship, patients passively let students practice on their bodies. Students nearing graduation experienced only external authenticity, creating uncertainty as a threshold for learning. Caring for patients with complex needs helped students overcome the threshold and experience internal authenticity. Supervisors' challenges were to balance patient care and student learning by working as a team. They supported students coping with the complex challenges on the ward. Students need to experience external and internal authenticity to make learning meaningful. Experiencing authenticity, involving meaning-making processes and knowledge construction, is linked to transformative learning and overcoming thresholds. Therefore, an explicit pedagogical framework, based on patient-centredness, peer learning and the supervisory team, creates the prerequisites for experiencing external and internal authenticity.

A validated autoantibody assay is available commercially (EarlyCDT®-Lung) to aid in the early detection of lung cancer and risk stratification in patients with pulmonary nodules detected by CT. Recent advances in high throughput (HTP) cloning and expression methods have been developed into a discovery pipeline to identify biomarkers that detect autoantibodies. The aim of this study was to demonstrate the successful clinical application of this strategy to add to the EarlyCDT-Lung panel in order to improve its sensitivity and specificity (and hence positive predictive value, (PPV)). Methods and Findings Serum from two matched independent cohorts of lung cancer patients were used (n = 100 and n = 165). Sixty nine proteins were initially screened on an abridged HTP version of the autoantibody ELISA using protein prepared on small scale by a HTP expression and purification screen. Promising leads were produced in shake flask culture and tested on the full assay. These results were analyzed in combination with those from the EarlyCDT-Lung panel in order to provide a set of re-optimized cut-offs. Five proteins that still displayed cancer/normal differentiation were tested for reproducibility and validation on a second batch of protein and a separate patient cohort. Addition of these proteins resulted in an improvement in the sensitivity and specificity of the test from 38% and 86% to 49% and 93% respectively (PPV improvement from 1 in 16 to 1 in 7). Conclusion This is a practical example of the value of investing resources to develop a HTP technology. Such technology may lead to improvement in the clinical utility of the EarlyCDT­-Lung test, and so further aid the early detection of lung cancer. PMID:23272083

    To identify a panel of tumor associated autoantibodies which can potentially be used as biomarkers for the early diagnosis of non-small cell lung cancer (NSCLC). Thirty-five unique and in-frame expressed phage proteins were isolated. Based on the gene expression profiling, four proteins were selected for further study. Both receiver operating characteristic curve analysis and leave-one-out method revealed that combined measurements of four antibodies produced have better predictive accuracies than any single marker alone. Leave-one-out validation also showed significant relevance with all stages of NSCLC patients. The panel of autoantibodies has a high potential for detecting early stage NSCLC. PMID:22713465

    Dissolution testing is frequently used to determine the rate and extent at which a drug is released from a dosage form, and it plays many important roles throughout drug product development. However, the traditional dissolution approach often emphasizes its application in quality control testing and usually strives to obtain 100% drug release. As a result, dissolution methods are not necessarily biorelevant and meaningful application of traditional dissolution methods in the early phases of drug product development can be very limited. This article will describe the development of a biorelevant in vitro dissolution method using USP apparatus 4, biorelevant media, and real-time online UV analysis. Several case studies in the areas of formulation selection, lot-to-lot variability, and food effect will be presented to demonstrate the application of this method in early phase formulation development. This biorelevant dissolution method using USP apparatus 4 provides a valuable tool to predict certain aspects of the in vivo drug release. It can be used to facilitate the formulation development/selection for pharmacokinetic (PK) and clinical studies. It may also potentially be used to minimize the number of PK studies, and to aid in the design of more efficient PK and clinical studies.

    Pre-deployment identification of soldiers at risk for long-term posttraumatic stress psychopathology after home coming is important to guide decisions about deployment. Early post-deployment identification can direct early interventions to those in need and thereby prevents the development of chronic psychopathology. Both hold significant public health benefits given large numbers of deployed soldiers, but has so far not been achieved. Here, we aim to assess the potential for pre- and early post-deployment prediction of resilience or posttraumatic stress development in soldiers by application of machine learning (ML) methods. ML feature selection and prediction algorithms were applied to a prospective cohort of 561 Danish soldiers deployed to Afghanistan in 2009 to identify unique risk indicators and forecast long-term posttraumatic stress responses. Robust pre- and early postdeployment risk indicators were identified, and included individual PTSD symptoms as well as total level of PTSD symptoms, previous trauma and treatment, negative emotions, and thought suppression. The predictive performance of these risk indicators combined was assessed by cross-validation. Together, these indicators forecasted long term posttraumatic stress responses with high accuracy (pre-deployment: AUC = 0.84 (95% CI = 0.81-0.87), post-deployment: AUC = 0.88 (95% CI = 0.85-0.91)). This study utilized a previously collected data set and was therefore not designed to exhaust the potential of ML methods. Further, the study relied solely on self-reported measures. Pre-deployment and early post-deployment identification of risk for long-term posttraumatic psychopathology are feasible and could greatly reduce the public health costs of war.

    Too difficult, too abstract, too theoretical - many first-year engineering students complain about their mathematics courses. The project MathePraxis aims to resolve this disaffection. It links mathematical methods as they are taught in the first semesters with practical problems from engineering applications - and thereby shall give first-year engineering students a vivid and convincing impression of where they will need mathematics in their later working life. But since real applications usually require more than basic mathematics and first-year engineering students typically are not experienced with construction, mensuration and the use of engineering software, such an approach is hard to realise. In this article, we show that it is possible. We report on the implementation of MathePraxis at Ruhr-Universität Bochum. We describe the set-up and the implementation of a course on designing a mass damper which combines basic mathematical techniques with an impressive experiment. In an accompanying evaluation, we have examined the students' motivation relating to mathematics. This opens up new perspectives how to address the need for a more practically oriented mathematical education in engineering sciences.

    Floods have caused devastating impacts to the environment and society in Awash River Basin, Ethiopia. Since flooding events are frequent, this marks the need to develop tools for flood early warning. In this study, we propose a satellite based flood index to identify the runoff source areas that largely contribute to extreme runoff production and floods in the basin. Satellite based products used for development of the flood index are CMORPH (Climate Prediction Center MORPHing technique: 0.25° by 0.25°, daily) product for calculation of the Standard Precipitation Index (SPI) and a Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM) for calculation of the Topographic Wetness Index (TWI). Other satellite products used in this study are for rainfall-runoff modelling to represent rainfall, potential evapotranspiration, vegetation cover and topography. Results of the study show that assessment of spatial and temporal rainfall variability by satellite products may well serve in flood early warning. Preliminary findings on effectiveness of the flood index developed in this study indicate that the index is well suited for flood early warning. The index combines SPI and TWI, and preliminary results illustrate the spatial distribution of likely runoff source areas that cause floods in flood prone areas.

  20. Application of the Maximum Amplitude-Early Rise Correlation to Cycle 23

    2004-01-01

    On the basis of the maximum amplitude-early rise correlation, cycle 23 could have been predicted to be about the size of the mean cycle as early as 12 mo following cycle minimum. Indeed, estimates for the size of cycle 23 throughout its rise consistently suggested a maximum amplitude that would not differ appreciably from the mean cycle, contrary to predictions based on precursor information. Because cycle 23 s average slope during the rising portion of the solar cycle measured 2.4, computed as the difference between the conventional maximum (120.8) and minimum (8) amplitudes divided by the ascent duration in months (47), statistically speaking, it should be a cycle of shorter period. Hence, conventional sunspot minimum for cycle 24 should occur before December 2006, probably near July 2006 (+/-4 mo). However, if cycle 23 proves to be a statistical outlier, then conventional sunspot minimum for cycle 24 would be delayed until after July 2007, probably near December 2007 (+/-4 mo). In anticipation of cycle 24, a chart and table are provided for easy monitoring of the nearness and size of its maximum amplitude once onset has occurred (with respect to the mean cycle and using the updated maximum amplitude-early rise relationship).

    The Colloquium on Human-Machine Communication by Voice highlighted the global technical community's focus on the problems and promise of voice-processing technology, particularly, speech recognition and speech synthesis. Clearly, there are many areas in both the research and development of these technologies that can be advanced significantly. However, it is also true that there are many applications of these technologies that are capable of commercialization now. Early successful commercialization of new technology is vital to ensure continuing interest in its development. This paper addresses efforts to commercialize speech technologies in two markets: telecommunications and aids for the handicapped. PMID:7479814

    A new metric for the evaluation of model performance in the field of virtual screening and quantitative structure-activity relationship applications is described. This metric has been termed the power metric and is defined as the fraction of the true positive rate divided by the sum of the true positive and false positive rates, for a given cutoff threshold. The performance of this metric is compared with alternative metrics such as the enrichment factor, the relative enrichment factor, the receiver operating curve enrichment factor, the correct classification rate, Matthews correlation coefficient and Cohen's kappa coefficient. The performance of this new metric is found to be quite robust with respect to variations in the applied cutoff threshold and ratio of the number of active compounds to the total number of compounds, and at the same time being sensitive to variations in model quality. It possesses the correct characteristics for its application in early-recognition virtual screening problems.

    Objectives Recent advances in mobile technology have opened up possibilities to provide strongly integrated mobile-based services in healthcare and telemedicine. Although the number of mobile Electronic Health Record (EHR) applications is large and growing, there is a paucity of evidence demonstrating the usage patterns of these mobile applications by healthcare providers. This study aimed to illustrate the deployment process for an integrated mobile EHR application and to analyze usage patterns after provision of the mobile EHR service. Methods We developed an integrated mobile application that aimed to enhance the mobility of healthcare providers by improving access to patient- and hospital-related information during their daily medical activities. The study included mobile EHR users who accessed patient healthcare records between May 2013 and May 2014. We performed a data analysis using a web server log file analyzer from the integrated EHR system. Cluster analysis was applied to longitudinal user data based on their application usage pattern. Results The mobile EHR service named M-UMIS has been in service since May 2013. Every healthcare provider in the hospital could access the mobile EHR service and view the medical charts of their patients. The frequency of using services and network packet transmission on the M-UMIS increased gradually during the study period. The most frequently accessed service in the menu was the patient list. Conclusions A better understanding regarding the adoption of mobile EHR applications by healthcare providers in patient-centered care provides useful information to guide the design and implementation of future applications.

    In 2009, Elena Long created the LGBT+ Physicists website (http://lgbtphysicists.x10hosting.com) as a warehouse for resources useful for sexual and gender minorities working in physics. This resource has grown to include networking resources, lists of LGBT-friendly universities and localities, recommendations for enacting positive change in physics communities, and out-reach to other STEM-oriented LGBT organizations. This has been possible in large part by the dynamic community of LGBT+ physicists and allies looking to make physics more welcoming towards our community. In 2011, Elena used hir position as Member at Large on the executive committee of the Forum of Graduate Student Affairs (FGSA) to conduct a climate survey that included, among other things, the first serious look at LGBT+ demographics in physics. The survey focused particularly on issues of language heard and harassment experienced by physicists and was broken down into categories based on race, physical and mental ability, gender, and sexuality. Furthermore, it examined the outcomes of experienced harassment and the reasons for when harassment was not reported. Due to the nature of the study, overlapping demographics, especially ``multiple minorities,'' were also explored. This talk will give a brief history of the LGBT+ Physicists resource as well as an overview of the FGSA study.

    To review membership application materials (especially rejected applications) to the American Academy of Neurology (AAN) during its formative years (1947-1953). Detailed study of materials in the AAN Historical Collection. The author identified 73 rejected applications. Rejected applicants (71 male, 2 female) lived in 25 states. The largest number was for the Associate membership category (49). These were individuals "in related fields who have made and are making contributions to the field of neurology." By contrast, few applicants to Active membership or Fellowship status were rejected. The largest numbers of rejectees were neuropsychiatrists (19), neurosurgeons (16), and psychiatrists (14). The AAN, established in the late 1940s, was a small and politically vulnerable organization. A defining feature of the fledgling society was its inclusiveness; its membership was less restrictive than that of the older American Neurological Association. At the same time, the society needed to preserve its core as a neurologic society rather than one of psychiatry or neurosurgery. Hence, the balance between inclusiveness and exclusive identity was a difficult one to maintain. The Associate membership category, more than any other, was at the heart of this issue of self-definition. Associate members were largely practitioners of psychiatry or neurosurgery. Their membership was a source of consternation and was to be carefully been held in check during these critical formative years. © 2014 American Academy of Neurology.

    To evaluate the long-term outcomes of pylorus-vagus-preserving partial gastrectomy for early gastric cancer in middle third of stomach. Between January 2004 and June 2009, 46 patients with early gastric cancer in middle third of stomach underwent pylorus-vagus-preserving partial gastrectomy (PPG) while another 85 patients had conventional distal gastrectomy (DG). Clinicopathologic data and follow-up results of two groups were analyzed retrospectively, including the results of subjective nutritional assessments, laboratory blood biochemical data, endoscopic findings of remnant stomach and total 5-year survival rates. Postprandial dumping syndrome occurred in 7 patients (8.2%) in DG group while no syndrome occurred in PPG group. The incidence of gallbladder stones at 18 months after operation in DG group was higher than that in PPG group. Significant difference existed between two groups (P<0.05). Even though no significant difference existed in laboratory blood biochemical data and endoscopic findings, PPG group recovered better and regurgitation was frequently found in DG group. Food residue in gastric remnant was frequently observed in PPG (31.1%) than in DG (10.8%, P<0.05) by endoscopic findings. At 2 years post-operation, the postoperative 5-year recurrence rate was 6.5% (2/46) in PPG group versus 8.2% (7/85) in DG group. However no significant difference existed between 2 groups (P=0.724). No significant difference existed between PPG group (91.3%) and DG group (90.6%) in overall 5-year survival rate. For early gastric cancer in middle third of stomach, pylorus-vagus-preserving partial gastrectomy is effective in maintaining postoperative function. And it has the same postoperative survival rate as conventional distal gastrectomy.

    The interest in adaptive study design is evident from the growing amount of clinical research employing this model in the mid to later stages of medicines development. Little has been published on the practical application and merits of adaptive study design in early phase clinical research. This paper describes a retrospective analysis performed on a sample of 29 industry lead adaptive early phase studies commencing between 1 January 2006 and 31 December 2010 in a clinical trials unit in London, England. All studies containing at least one adaptive feature in the original protocol were included in the analysis. The scope of the analysis was to assess whether the use of adaptive study designs provided tangible benefits over the use of conventional study designs using time savings as the main measure. We conclude that the use of adaptive study design saves time in early phase research programs. This is achieved by abolishing the need for substantial amendments or by mitigating their impact on timelines and by using adaptive scheduling efficiencies.

    We explore the use of collocated GPS and seismic sensors for earthquake monitoring and early warning. The GPS and seismic data collected during the 2011 Tohoku-Oki (Japan) and the 2010 El Mayor-Cucapah (Mexico) earthquakes are analyzed by using a tightly-coupled integration. The performance of the integrated results is validated by both time and frequency domain analysis. We detect the P-wave arrival and observe small-scale features of the movement from the integrated results and locate the epicenter. Meanwhile, permanent offsets are extracted from the integrated displacements highly accurately and used for reliable fault slip inversion and magnitude estimation. PMID:24284765

    This is a randomized controlled prospective trial with two parallel groups. The objective of this study was to determine whether early application of tail nerve electrical stimulation (TANES)-induced walking training can improve the locomotor function. This study was conducted in SCS Research Center in Colorado, USA. A contusion injury to spinal cord T10 was produced using the New York University impactor device with a 25 -mm height setting in female, adult Long-Evans rats. Injured rats were randomly divided into two groups (n=12 per group). One group was subjected to TANES-induced walking training 2 weeks post injury, and the other group, as control, received no TANES-induced walking training. Restorations of behavior and conduction were assessed using the Basso, Beattie and Bresnahan open-field rating scale, horizontal ladder rung walking test and electrophysiological test (Hoffmann reflex). Early application of TANES-induced walking training significantly improved the recovery of locomotor function and benefited the restoration of Hoffmann reflex. TANES-induced walking training is a useful method to promote locomotor recovery in rats with spinal cord injury.

    The traditional values of Chinese culture promote care and respect toward older adults. While it appears to be ironic to discuss issues of abuse and neglect in the Chinese culture, research findings in Chinese societies do indicate the occurrences of such problems. However, little research on the abuse and neglect of older Chinese in Western societies has been available. This study aims to examine the incidence of abuse and neglect and the associated correlates based on data collected from a random sample of 2,272 aging Chinese 55 years and older in seven Canadian cities. The findings show that 4.5% of the participants reported experiencing at least one incident of maltreatment or neglect within the past year. The most common forms of neglect and abuse experienced by the aging Chinese include being scolded, yelled at, treated impolitely all the time, and ridiculed. Close family members such as spouses and sons are those that most commonly maltreat older Chinese. Those who were more likely to report at least one incident of maltreatment or neglect were older adults living with others; they tended to have no education, more access barriers, more chronic illnesses, less favorable mental health, and a higher level of identification with Chinese cultural values. The findings implied that the face value of respect and care received by older people in Chinese culture should not be taken for granted. Culturally appropriate precautionary steps are needed for prevention and early problem identification.

    The aim of this study is to develop a Financial Early Warning System (FEWS) for hospitals by using data mining. A data mining method, Chi-Square Automatic Interaction Detector (CHAID) decision tree algorithm, was used in the study for financial profiling and developing FEWS. The study was conducted in Turkish Ministry of Health's public hospitals which were in financial distress and in need of urgent solutions for financial issues. 839 hospitals were covered and financial data of the year 2008 was obtained from Ministry of Health. As a result of the study, it was determined that 28 hospitals (3.34%) had good financial performance, and 811 hospitals (96.66%) had poor financial performance. According to FEWS, the covered hospitals were categorized into 11 different financial risk profiles, and it was found that 6 variables affected financial risk of hospitals. According to the profiles of hospitals in financial distress, one early warning signal was detected and financial road map was developed for risk mitigation.

    This project was to investigate models for aqueous sedimentation on early Mars from fluid evaporation. Results focused on three specific areas: (1) First, a fluid evaporation model incorporating iron minerals was developed to compute the evaporation of a likely solution on early Mars derived from the weathering of mafic rock. (2) Second, the fluid evaporation model was applied to salts within Martian meteorites, specifically salts in the nakhlites and ALH84001. Evaporation models were found to be consistent with the mineralogy of salt assemblages-anhydrite, gypsum, Fe-Mg-Ca carbonates, halite, clays-- and the concentric chemical fractionation of Ca-to Mg-rich carbonate rosettes in ALH84001. We made progress in further developing our models of fluid concentration by contributing to updating the FREZCHEM model. (3) Third, theoretical investigation was done to determine the thermodynamics and kinetics involved in the formation of gray, crystalline hematite. This mineral, of probable ancient aqueous origin, has been observed in several areas on the surface of Mars by the Thermal Emission Spectrometer on Mars Global Surveyor. The "Opportunity" Mars Exploration Rover has also detected gray hematite at its landing site in Meridiani Planum. We investigated how gray hematite can be formed via atmospheric oxidation, aqueous precipitation and subsequent diagenesis, or hydrothermal processes. We also studied the geomorphology of the Aram Chaos hematite region using Mars Orbiter Camera (MOC) images.

    Sinkholes represent a natural risk that may hit catastrophically without clearly detectible precursors. However, they are often overlooked by people and administrators. Therefore sinkhole monitoring and associated early warnings constitute important research topics but, currently, only a few papers about sinkhole prediction can be found. In this paper an experience of sinkhole monitoring and early warning with GB-InSAR is described. The latter is a highly precise instrument that is able to produce displacement maps with metric spatial resolution. The described activities were carried out on Elba Island (central Italy), where karstified limestone set off the occurrence of nine sinkholes since 2008, all within less than 3000 m2, causing major damage to an important road and many indirect losses. In 1 year of monitoring two deforming areas were detected, and the point where a sinkhole was about to propagate to the street level was predicted, thus permitting the preventive closure of the road. The deformation area was larger than the hole generated by the sinkhole, thus showing a subsidence that continued for a prolonged time even after the cavity was filled up. The occurrence of a 1.5-m-wide sinkhole, undetected by the GB-InSAR, also showed the lower detection limit of the instrument.

    To illustrate the efficiency of cumulative sum (CUSUM) in pre-warning of the influenza peak in Beijing. CUSUM was used to analyze the data of influenza like illness (ILI), and the results of the influenza laboratory surveillance was regarded as the gold standard to judge the approaching of the influenza peak. The surveillance was launched in 421 hospitals in Beijing during the 2009 to 2010 influenza season, while the influenza laboratory surveillance was launched by 7 collaborative laboratories. From Jun. 2009 to Apr. 2010, the average ILI percentage in the 421 hospitals was 2.56%. In the study, 19 262 pharyngeal swab samples were collected from the ILI cases in 11 hospitals and 5 045 of them were tested positive for the influenza virus, with the novel swine-origin influenza A H1N1 virus dominating. After analyzing of the ILI surveillance data with CUSUM, it was found that the ILI surveillance in Beijing could make a satisfactory early warning for the approaching of the influenza peak referring to the gold standard based on the influenza laboratory results. It could give the prediction and early warning for the influenza peak efficiently and precisely, by using CUSUM to analyze the influenza surveillance data of Beijing.

    To prevent the recurrence of earlobe keloids after surgical removal, a reliable and safe postoperative treatment method is critical. To the authors' knowledge, no studies have elucidated the most effective postoperative dressing method for preventing the recurrence of earlobe keloids. This study aimed to compare keloid recurrence rates in patients whose keloids were dressed using conventional methods (plain gauze or a polyvinyl alcohol sponge) with those of a matched cohort of patients whose keloids were dressed using magnets combined with hydrocolloid materials. This observational case-control study compared a retrospective cohort of patients whose keloids were dressed using conventional methods with a matched prospective cohort of patients whose keloids were dressed using magnets combined with hydrocolloid materials. The study included patients with pathologically confirmed earlobe keloids that were surgically excised with primary closure. Patients 8 years of age or older underwent adjuvant pressure therapy with magnets at the study hospital. Patients were excluded from the study if they were unavailable for follow-up evaluation, if they had received additional adjuvant therapy during treatment, or if histologic confirmation of a keloid was not obtained. Matched-pair analysis was performed using the McNemar test. Treatment outcome was evaluated as recurrence or nonrecurrence. Overall, 9 (11.2%) of the 80 study patients experienced recurrence. The recurrence rate was significantly lower in the matched case group (2 of 40, 5%) than in the matched control group (7 of 40, 17.5%) during the follow-up period of 18 months (p=0.0253). The authors' novel dressing of magnets and hydrocolloid materials appears to be effective in reducing earlobe keloid recurrence.

    There is broad interest in predicting the clinical course of mental disorders from early, multimodal clinical and biological information. Current computational models, however, constitute a significant barrier to realizing this goal. The early identification of trauma survivors at risk of post-traumatic stress disorder (PTSD) is plausible given the disorder's salient onset and the abundance of putative biological and clinical risk indicators. This work evaluates the ability of Machine Learning (ML) forecasting approaches to identify and integrate a panel of unique predictive characteristics and determine their accuracy in forecasting non-remitting PTSD from information collected within 10 days of a traumatic event. Data on event characteristics, emergency department observations, and early symptoms were collected in 957 trauma survivors, followed for fifteen months. An ML feature selection algorithm identified a set of predictors that rendered all others redundant. Support Vector Machines (SVMs) as well as other ML classification algorithms were used to evaluate the forecasting accuracy of i) ML selected features, ii) all available features without selection, and iii) Acute Stress Disorder (ASD) symptoms alone. SVM also compared the prediction of a) PTSD diagnostic status at 15 months to b) posterior probability of membership in an empirically derived non-remitting PTSD symptom trajectory. Results are expressed as mean Area Under Receiver Operating Characteristics Curve (AUC). The feature selection algorithm identified 16 predictors, present in ≥ 95% cross-validation trials. The accuracy of predicting non-remitting PTSD from that set (AUC = .77) did not differ from predicting from all available information (AUC = .78). Predicting from ASD symptoms was not better then chance (AUC = .60). The prediction of PTSD status was less accurate than that of membership in a non-remitting trajectory (AUC = .71). ML methods may fill a critical gap in forecasting PTSD. The

    Early dental caries detection facilitates implementation of non-surgical methods for arresting caries progression and promoting tooth remineralization. We present a method based on Raman spectroscopy with near-IR laser excitation to provide biochemical contrast for detecting and characterizing incipient carious lesions found in extracted human teeth. Changes in Raman spectra are observed in PO 4 3- vibrations arising from hydroxyapatite of mineralized tooth tissue. Examination of various intensities of the PO 4 3- ν2, ν3, ν4 vibrations showed consistent increased intensities in spectra of carious lesions compared to sound enamel. The spectral changes are attributed to demineralization-induced alterations of enamel crystallite morphology and/or orientation. This hypothesis is supported by reduced Raman polarization anisotropy derived from polarized Raman spectra of carious lesions. Polarized Raman spectral imaging of carious lesions found on whole (i.e. un-sectioned) tooth samples will also be presented.

    The paper describes microgravity science opportunities inherent to the restructured Space Station and presents a synopsis of the scientific utilization plan for the first two years of ground-tended operations. In the ground-tended utilization mode the Space Station is a large free-flyer providing a continuous microgravity environment unmatched by any other platform within any existing U.S. program. It is pointed out that the importance of this period of early Space Station mixed-mode utilization between crew-tended and ground-tended approaches is of such magnitude that Station-based microgravity science experiments many become benchmarks to the disciplines involved. The traffic model that is currently being pursued is designed to maximize this opportunity for the U.S. microgravity science community.

  9. Paleoclimate from fossil plants and application to the early Cenozoic Rocky Mountains

    2011-12-01

    Wladimir Köppen called vegetation "crystallized, visible climate," and his metaphor encouraged paleobotanists to climb the chain of inference from fossil plants to paleovegetation to paleoclimate. Inferring paleovegetation from fossils has turned out to be very difficult, however, and today most paleobotanical methods for inferring paleoclimate do not try to reconstruct paleovegetation as a first step. Three major approaches are widely use to infer paleoclimate from plant fossils: 1) phylogenetic inferences rely on the climatic distributions of extant relatives of fossils, 2) morphological inferences use present-day correlations of climate with plant morphology (e.g, leaf shape, wood anatomy), and 3) chemical inferences rely on correlations between climate and the stable isotopic composition of plants or organic compounds. Each approach makes assumptions that are hard to verify. Phylogenetic inference depends on accurate identification of fossils, and also assumes that evolution and/or extinction has not shifted the climatic distributions of plant lineages through time. On average this assumption is less valid for older time periods, but probably it is not radically wrong for the early Cenozoic. Morphological approaches don't require taxonomic identification of plant fossils, but do assume that correlations between plant form and climate have been constant over time. This assumption is bolstered if the ecophysiological cause of the morphology-climate correlation is well understood, but often it isn't. Stable isotopic approaches assume that present-day correlations between isotopic composition and climate apply to the past. Commonly the chemical and physiological mechanisms responsible for the correlation are moderately well known, but often the variation among different taxonomic and functional groups of plants is poorly characterized. In spite of limitations and uncertainties on all methods for inferring paleoclimate from fossil plants, broad patterns emerge from

    The ageing of the vascular tree is a fundamental reflection of biological ageing in general and a determinant of organ function. In the arterial wall this is characterized by a reduction in the elastin content, as well as by an increased content of collagen and its cross-linkages, leading to increased arterial stiffness and elevated central as well as brachial blood pressure, accompanied by increased SBP variability. In recent years a better understanding of these processes have led to the proposal of a condition named early vascular ageing (EVA) in patients with increased arterial stiffness for their age and sex. This is a condition that could increase cardiovascular risk and is associated with various degrees of cognitive dysfunction, as well as other features of biological ageing. This brief review aims to give an update on EVA and how the concept can be used in clinical practice.

    The development of efficient stroke-detection methods is of significant importance in today's society due to the effects and impact of stroke on health and economy worldwide. This study focuses on Human Activity Recognition (HAR), which is a key component in developing an early stroke-diagnosis tool. An overview of the proposed global approach able to discriminate normal resting from stroke-related paralysis is detailed. The main contributions include an extension of the Genetic Fuzzy Finite State Machine (GFFSM) method and a new hybrid feature selection (FS) algorithm involving Principal Component Analysis (PCA) and a voting scheme putting the cross-validation results together. Experimental results show that the proposed approach is a well-performing HAR tool that can be successfully embedded in devices.

    This report was funded by the U.S. Department of Energy's (DOE's) National Energy Technology Laboratory (NETL) Existing Plants Research Program, which has an energy-water research effort that focuses on water use at power plants. This study complements the overall research effort of the Existing Plants Research Program by evaluating water issues that could impact power plants. A growing challenge to the economic production of electricity from coal-fired power plants is the demand for freshwater, particularly in light of the projected trends for increasing demands and decreasing supplies of freshwater. Nanotechnology uses the unique chemical, physical, and biological properties that aremore » associated with materials at the nanoscale to create and use materials, devices, and systems with new functions and properties. It is possible that nanotechnology may open the door to a variety of potentially interesting ways to reduce freshwater consumption at power plants. This report provides an overview of how applications of nanotechnology could potentially help reduce freshwater use at coal-fired power plants. It was developed by (1) identifying areas within a coal-fired power plant's operations where freshwater use occurs and could possibly be reduced, (2) conducting a literature review to identify potential applications of nanotechnology for facilitating such reductions, and (3) collecting additional information on potential applications from researchers and companies to clarify or expand on information obtained from the literature. Opportunities, areas, and processes for reducing freshwater use in coal-fired power plants considered in this report include the use of nontraditional waters in process and cooling water systems, carbon capture alternatives, more efficient processes for removing sulfur dioxide and nitrogen oxides, coolants that have higher thermal conductivities than water alone, energy storage options, and a variety of plant inefficiencies, which, if

To help overcome these challenges, this study analyzes opportunities for their near-term deployment in five categories of non-motive equipment: portable power, construction equipment, airport ground support equipment, telecom backup power, and man-portable power and personal electronics. To this end, researchers engaged end users, equipment manufacturers, and technical experts via workshops, interviews, and electronic means, and then compiled these data into meaningful and realistic requirements for hydrogen storage in specific target applications. In additionmore » to developing these requirements, end-user benefits (e.g., low noise and emissions, high efficiency, potentially lower maintenance costs) and concerns (e.g., capital cost, hydrogen availability) of hydrogen fuel cells in these applications were identified.

  17. Application of Radar-Based Accumulated Rainfall Products for Early Detection of Heavy Rainfall Occurrence

    2016-12-01

    In Japan, river and debris flow disasters have been frequently caused by heavy rainfall occurrence under the influence of the activity of a stationary front and associated inflow of a large amount of moisture into the front. However, it is very difficult to predict numerically-based heavy rainfall and associated landslide accurately. Therefore, the use of meteorological radar information is required for enhancing decision-making ability to urge the evacuation of local residents by local government staffs prior to the occurrence of the heavy rainfall disaster. It is also desirable that the local residents acquire the ability to determine the evacuation immediately after confirming radar information by themselves. Actually, it is difficult for untrained local residents and local government staffs to easily recognize where heavy rainfall occurs locally for a couple of hours. This reason is that the image of radar echoes is equivalent to instant electromagnetic distribution measured per a couple of minutes, and the distribution of the radar echoes moves together with the movement of a synoptic system. Therefore, in this study, considering that the movement of radar echoes also may stop in a specific area if stationary front system becomes dominant, radar-based accumulated rainfall information is defined here. The rainfall product is derived by the integration of radar intensity measured every ten minutes during previous 1 hours. Using this product, it was investigated whether and how the radar-based accumulated rainfall displayed at an interval of ten minutes can be applied for early detection of heavy rainfall occurrence. The results are summarized as follows. 1) Radar-based accumulated rainfall products could confirm that some of stationary heavy rainfall systems had already appeared prior to disaster occurrence, and clearly identify the movement of heavy rainfall area. 2) Moreover, accumulated area of rainfall could be visually and easily identified, compared with

    Human exploration of Mars is a key goal in NASA's exploration planning in the next 20 years. Maintaining crew health and good vision is certainly an important aspect of achieving a successful mission. Continuous radiation exposure is a risk factor for radiation-induced cataracts in astronauts because radiation exposure in space travel has the potential of accelerating the aging process (ref. 1). A patented compact device (ref. 2) based on the technique of dynamic light scattering (DLS) was designed for monitoring an astronaut's ocular health during long-duration space travel. This capability of early diagnosis, unmatched by any other clinical technique in use today, may enable prompt initiation of preventive/curative therapy. An Internet web-based system integrating photon correlation data and controlling the hardware to monitor cataract development in vivo at a remote site in real time (teleophthalmology) is currently being developed. The new technology detects cataracts very early (at the molecular level). Cataract studies onboard the International Space Station will be helpful in quantifying any adverse effect of radiation to ocular health. The normal lens in a human eye, situated behind the cornea, is a transparent tissue. It contains 35 wt % protein and 65 wt % water. Aging, disease (e.g., diabetes), smoking, dehydration, malnutrition, and exposure to ultraviolet light and ionizing radiation can cause agglomeration of the lens proteins. Protein aggregation can take place anywhere in the lens, causing lens opacity. The aggregation and opacification could produce nuclear (central portion of the lens) or cortical (peripheral) cataracts. Nuclear and posterior subcapsular (the membrane's capsule surrounds the whole lens) cataracts, being on the visual optical axis of the eye, cause visual impairment that can finally lead to blindness. The lens proteins, in their native state, are small in size. As a cataract develops, this size grows from a few nanometers

    The present study describes a novel application for use in the monitoring of municipal solid waste, based on distributed sensor technology and geographical information systems. Original field testing and evaluation of the application were carried out in Pudong, Shanghai (PR China). The local waste management system in Pudong features particular requirements related to the rapidly increasing rate of waste production. In view of the fact that collected waste is currently deployed to landfills or to incineration plants within the context investigated, the key aspects to be taken into account in waste collection procedures include monitoring of the overall amount of waste produced, quantitative measurement of the waste present at each collection point and identification of classes of material present in the collected waste. The case study described herein focuses particularly on the above mentioned aspects, proposing the implementation of a network of sensorized waste containers linked to a data management system. Containers used were equipped with a set of sensors mounted onto standard waste bins. The design, implementation and validation procedures applied are subsequently described. The main aim to be achieved by data collection and evaluation was to provide for feasibility analysis of the final device. Data pertaining to the content of waste containers, sampled and processed by means of devices validated on two purpose-designed prototypes, were therefore uploaded to a central monitoring server using GPRS connection. The data monitoring and management modules are integrated into an existing application used by local municipal authorities. A field test campaign was performed in the Pudong area. The system was evaluated in terms of real data flow from the network nodes (containers) as well as in terms of optimization functions, such as collection vehicle routing and scheduling. The most important outcomes obtained were related to calculations of waste weight and

    The objective of this study was to determine if very early ultrasonographic measurements obtained from human and baboon are comparable. For this purpose, the gestational, amniotic and yolk sacs, embryonic crown rump length (CRL) and heart rate were measured ultrasonographically between 35 and 47 days from the mean day of a three-day mating period in baboons (n=18) and between 42 to 58 days from fertilization as calculated from the CRL measurements in human pregnancies (n=82). Ultrasonographic measurements from both species were then plotted in the same graph using Carnegie stages of embryonic development as the independent variable to allow for visual comparisons. Mean gestational age at ultrasonographic studies was significantly different for humans and baboons (50.4 vs. 41 days, respectively; p>0.01). Significant correlations (p>0.01) were noted between ultrasonographic measurements and Carnegie stages of development in both humans and baboons. Only the gestational and the yolk sacs were significantly smaller in baboons than in humans (p>0.05). The findings that embryonic CRL, extra-embryonic space and heart rate are very similar between the 17th and 23rd Carnegie developmental stages make the baboon a promising surrogate of human pregnancy for investigations using celocentesis.

    A multi-channel continuous toxicity monitoring system developed in our laboratory, based on two-stage mini-bioreactors, was successfully implemented in the form of computer-based data acquisition. The multi-channel system consists of a series of a two-stage minibioreactor systems connected by a fiber optic probe to a luminometer, and uses genetically engineered bioluminescent bacteria for the detection of the potential toxicity from the soluble chemicals. This system can be stably and continuously operated due to the separation of the culture reactor from the test reactor and accomplish easy and long-term monitoring without system shut down by abrupt inflows of severe polluting chemicals. Four different recombinant bioluminescent bacteria were used in different channels so that the modes of the samples toxicities can be reasonably identified and evaluated based upon the response signature of each channel. The bioluminescent signatures were delivered from four channels by switching one at once, while the data is automatically logged to an IBM compatible computer. We also achieved the enhancement of the system through the manipulation of the dilution rate and the use of thermo-lux fusion strains. Finally, this system is now being implemented to a drinking water reservoir and river for remote sensing as an early warning system.

    Earthquake Early Warning System (EEWS) is an effective approach to mitigate earthquake damage. In this study, we used the seismic record by the Kiban Kyoshin network (KiK-net), because it has dense station coverage and co-located borehole strong-motion seismometers along with the free-surface strong-motion seismometers. We used inland earthquakes with moment magnitude (Mw) from 5.0 to 7.3 between 1998 and 2012. We choose 135 events and 10950 strong ground accelerograms recorded by the 696 strong ground accelerographs. Both the free-surface and the borehole data are used to calculate τc and Pd, respectively. The results show that τc*Pd has a good correlation with PGV and is a robust parameter for assessing the potential of damaging earthquake. We propose the value of τc*Pd determined from seconds after the arrival of P wave could be a threshold for the on-site type of EEW.

    Fluorescence is a tool widely employed in biological assays. Fluorescent semiconducting nanocrystals, quantum dots (QDs), are beginning to find their way into the tool box of many biologist, chemist and biochemist. These quantum dots are an attractive alternative to the traditional organic dyes due to their broad excitation spectra, narrow emission spectra and photostability. Non-specific binding is a frequently encountered problem with fluorescent labeling in biological assays. In these studies various cell lines were examined for non-specific binding to quantum dots. Evidence suggests that non-specific binding is related to cell type and, may be significantly reduced by functionalizing quantum dots with polyethyleneglycol ligands (PEG). In addition quantum dots were used to detect and monitor the progession of the viral glycoproteins ,F (fusion) and G (attachment), from Respiratory Syncytial Virus (RSV) in HEp-2 cells. RSV is the most common cause of lower respiratory tract infection in children worldwide and the most common cause of hospitalization of infants in the US. Antiviral therapy is available for treatment of RSV but is only effective if given within the first 48 hours of infection. Existing test methods require a virus level of at least 1000-fold of the amount needed for infection of most children and require several days to weeks to obtain results. The use of quantum dots may provide an early, rapid method for detection and provide insight into the trafficking of viral proteins during the course of infection.

    Recent blackouts of power systems in North America and throughout the world have shown how critical a reliable power system is to modern societies, and the enormous economic and societal damage a blackout can cause. It has been noted that unanticipated operation of protection systems can contribute to cascading phenomena and, ultimately, blackouts. This project developed and field-tested two methods of Adaptive Protection systems utilizing synchrophasor data. One method detects conditions of system stress that can lead to unintended relay operation, and initiates a supervisory signal to modify relay response in real time to avoid false trips. The second methodmore » detects the possibility of false trips of impedance relays as stable system swings “encroach” on the relays’ impedance zones, and produces an early warning so that relay engineers can re-evaluate relay settings. In addition, real-time synchrophasor data produced by this project was used to develop advanced visualization techniques for display of synchrophasor data to utility operators and engineers.« less

    The Individuals with Disabilities Act was implemented in 1975 to assure that all children aged 0-21 years old have access and the right to an equal education. However, young children with disabilities continue to need additional support to meet the reading readiness standards as outlined in The No Child Left Behind legislation (2004). Although all children benefit from readiness skills, it is essential for children with special needs. With the technology boom of the past decade, assistive technology (AT) has been used increasingly to enhance emerging literacy skills. In order to identify current trends in the use of AT as a means to enhance emergent literacy skills in young children with disabilities, a systematic review of the literature was undertaken. The findings from this review support the scarcity of empirical research demonstrating the benefit of AT to promote emergent literacy with young children with disabilities. We also found a need for evidence supporting education approaches for the proper use of AT in early childhood literacy as well as little family knowledge regarding the implementation and instructional use of AT.

    This article describes guiding principles in early intervention (EI) and demonstrates how speech-language pathologists (SLPs) can apply these principles to best serve infants and toddlers with communication and related problems and their families. Four principles guide the implementation of speech-language pathology services. EI services are services that are (a) family centered and culturally and linguistically responsive; (b) developmentally supportive, promoting children's participation in their natural environments; (c) comprehensive, coordinated, and team based; and (d) based on the highest quality evidence available. Actual clinical scenarios are presented to illustrate each principle. The four principles provide a framework for the wide range of roles and responsibilities assumed by SLPs in EI: (a) screening/evaluation/assessment, (b) goal setting and intervention, (c) consultation with and education for team members, (d) service coordination, (e) transition planning, and (f) advocacy. It is critical that families of infants and toddlers who are at risk for, or who have been diagnosed with, communication disorders receive all necessary services and supports. EI services should be tailored to the individual and the changing needs, preferences, and priorities of each family. The earlier services are provided, the more likely is the child's chance to develop effective communication.

    This talk will review the status and progress of the NASA/Global Modeling and Assimilation Office (GMAO) atmospheric global reanalysis project called the Modern Era Retrospective-Analysis for Research and Applications (MERRA). An overview of NASA's emerging capabilities for assimilating a variety of other Earth Science observations of the land, ocean, and atmospheric constituents will also be presented. MERRA supports NASA Earth science by synthesizing the current suite of research satellite observations in a climate data context (covering the period 1979-present), and by providing the science and applications communities with of a broad range of weather and climate data with an emphasis on improved estimates of the hydrological cycle. MERRA is based on a major new version of the Goddard Earth Observing System Data Assimilation System (GEOS-5), that includes the Earth System Modeling Framework (ESMF)-based GEOS-5 atmospheric general circulation model and the new NOAA National Centers for Environmental Prediction (NCEP) unified grid-point statistical interpolation (GST) analysis scheme developed as a collaborative effort between NCEP and the GMAO. In addition to MERRA, the GMAO is developing new capabilities in aerosol and constituent assimilation, ocean, ocean biology, and land surface assimilation. This includes the development of an assimilation capability for tropospheric air quality monitoring and prediction, the development of a carbon-cycle modeling and assimilation system, and an ocean data assimilation system for use in coupled short-term climate forecasting.

The authors believe this is a promising approach to driving down healthcare costs, supporting standards evolution, accommodating differences in care workflow, fostering competition in the market, and accelerating innovation. The Office of the National Coordinator for Health Information Technology, through the Strategic Health IT Advanced Research Projects (SHARP) Program, funds the project. The SMART team has focused on enabling the property of substitutability through an app programming interface leveraging web standards, presenting predictable data payloads, and abstracting away many details of enterprise health information technology systems. Containers--health information technology systems, such as electronic health records (EHR), personally controlled health records, and health information exchanges that use the SMART app programming interface or a portion of it--marshal data sources and present data simply, reliably, and consistently to apps. The SMART team has completed the first phase of the project (a) defining an app programming interface, (b) developing containers, and (c) producing a set of charter apps that showcase the system capabilities. A focal point of this phase was the SMART Apps Challenge, publicized by the White House, using http://www.challenge.gov website, and generating 15 app submissions with diverse functionality. Key strategic decisions must be made about the most effective market for further disseminating SMART: existing market-leading EHR vendors, new entrants into the EHR market, or other stakeholders such as health information exchanges.

Interviews were held with 19 women, who were experiencing conjugal violence, and who were resident in a community in Salvador, Bahia, Brazil. The project was approved by the Research Ethics Committee (N. 42/2011). the data was organized using the Discourse of the Collective Subject, identifying the summary central ideas: they witnessed violence between their parents; they suffered repercussions from the violence between their parents: they were angry about the mother's submission to her partner; and they reproduced the conjugal violence. The discourse showed that the women witnessed, in childhood and adolescence, violence between their parents, and were injured both physically and psychologically. As a result of the mother's submission, feelings of anger arose in the children. However, in the adult phase of their own lives, they noticed that their conjugal life resembled that of their parents, reproducing the violence. investment is necessary in strategies designed to break inter-generational violence, and the health professionals are important in this process, as it is a phenomenon with repercussions in health. Because they work in the Family Health Strategy, which focuses on the prevention of harm and illness, health promotion and interdepartmentality, the nurses are essential in the process of preventing and confronting this phenomenon.

    Little research on adolescents has examined developmentally normative facets of sexuality that are not obviously linked to physical health. The purpose of this secondary data analysis was to qualitatively analyze adolescents’ thoughts about and experiences with sexual pleasure. The study sample consisted of 56 sexually experienced, ethnically diverse, predominantly female adolescents who were participating in a web-based intervention to promote healthy sexual decision-making. Comments on one message board, Sexual Pleasure: Does It Matter to You?, provided an opportunity to examine adolescents’ thoughts about and experiences with sexual pleasure, as well as their communication with partners about that topic. Adolescents’ comments demonstrated that they experience difficulties with pleasure in their sexual relationships. Adolescents generally believed that men are more likely than women to feel pleasure due to differences that include biology, understanding of one’s body, and control over partnered sexual behavior. Adolescents defined inequality of received pleasure differently and discussed contexts in which inequality may be acceptable. Adolescents expressed motivation to communicate with partners about sexual pleasure. However, their statements suggested they often lack the skills to do so. Future prevention and intervention programs should equip adolescents with skills to communicate with partners about sexual pleasure. PMID:27120115

    2004-12-01

    During the early twentieth century several toy manufacturers around the globe introduced construction toys in the form of sets of metal parts which could be assembled into a variety of models. The two most successful were the Erector Set, introduced in the United States by A.C. Gilbert in 1913, and the Meccano Set, patented in 1901 in England by Frank Hornby. Whereas the Erector Set never developed beyond being a child's toy, Hornby envisioned his Meccano system as providing a way to teach principles of mechanical engineering to young schoolboys. Indeed, his sets were first marketed under the name "Mechanics Made Easy", and were endorsed by Dr. H.S. Hele-Shaw, Head of the Engineering Department at Liverpool University. Popularity of the new Meccano sets spread throughout the world, spawning the formation of numerous amateur societies composed of adolescent boys and an increasing number of adult hobbyists. The variety of parts increased during the first third of the century, and increasingly sophisticated models were constructed and exhibited in competitive events. Among these were several clocks of remarkable accuracy, and at least one equatorial mounting for a small astronomical telescope. At the same time, many university science and engineering departments found these interchangeable metal parts invaluable in the construction of experimental apparatus. In 1934 a small-scale replica of Vannevar Bush's Differential Analyzer was constructed at the University of Manchester, and used for many years to perform mathematical computations. The introduction in 1928 of a flanged ring with 73 (a sub-multiple of 365) teeth allowed for construction of accurate orreries and astronomical clocks. The most remarkable of these was the Astronomical Clock constructed in the period 1924-1932 by M. Alexandre Rahm of Paris.

    Economic incentives have spurred numerous applications of genetically engineered organisms in manufacture of pharmaceuticals and industrial chemicals. These successes, involving a variety of methods of genetic manipulation, have dispelled early fears that genetic engineering could not be handled safely, even in the laboratory. Consequently, the potential for applications in the wider environment without physical containment is being considered for agriculture, mining, pollution control, and pest control. These proposed applications range from modest extensions of current plant breeding techniques for new disease-resistant species to radical combinations of organisms (for example, nitrogen-fixing corn plants). These applications raise concerns about potential ecological impacts (see chapter 5), largely because of adverse experiences with both deliberate and inadvertent introductions of nonindigenous species.

    One of the main objective of the WP7 (Strategic Applications and Capacity Building) in the framework of the REAKT-Strategies and tools for Real Time Earthquake RisK ReducTion FP7 European project, is to evaluate the effectiveness of EEW and real-time risk assessment procedures in reducing seismic risk to various industrial partners and end-users. In the context of the REAKT project, the AMRA-RISSCLab group is engaged in a feasibility study on the application of earthquake early-warning procedures in two high schools located in the Irpinia region (South Italy), an area that in the 1980 was struck by a magnitude 6.9 earthquake. In this work we report on the activities carried out during the last 24 Months at the school ITIS 'E. Majorana', located in Somma Vesuviana, a village in the neighbourhood of Naples. In order to perform a continuous seismic monitoring of the site, which includes a rather complex structure building, 5 accelerometric stations have been installed in different part of the school. In particular, a 24-bit ADC (Sigma/Delta) Agecodagis-Kefren data-logger has been installed with a Guralp CMG-5TC accelerometer with a 0.25g full-scale in the school courtyard, while 4 SOSEWIN sensors have been also installed at different locations within the building. Commercial ADSL lines provide transmission of real-time data to the EEW centre. Data streams are now acquired in real-time in the PRESToPlus (regional and on-site, threshold-based early-warning) software platform [1]. The recent December 29, 2013 M 5.1 Monti del Matese Earthquake, gave us the unique opportunity to use real strong motion data to test the performance of threshold-based early warning method at the school. The on-site method [2] aims to define alert levels at the monitored site. In particular, at each station the characteristic P-waves period (τc) and the peak displacement (Pd) are measured on the initial P-wave signal. They are compared with threshold values, previously established through an

    Cellular heterogeneity within a cell population is a common phenomenon in multicellular organisms, tissues, cultured cells, and even FACS-sorted subpopulations. Important information may be masked if the cells are studied as a mass. Transcriptome profiling is a parameter that has been intensively studied, and relatively easier to address than protein composition. To understand the basis and importance of heterogeneity and stochastic aspects of the cell function and its mechanisms, it is essential to examine transcriptomes of a panel of single cells. High-throughput technologies, starting from microarrays and now RNA-seq, provide a full view of the expression of transcriptomes but are limited by the amount of RNA for analysis. Recently, several new approaches for amplification and sequencing the transcriptome of single cells or a limited low number of cells have been developed and applied. In this review, we summarize these major strategies, such as PCR-based methods, IVT-based methods, phi29-DNA polymerase-based methods, and several other methods, including their principles, characteristics, advantages, and limitations, with representative applications in cancer stem cells, early development, and embryonic stem cells. The prospects for development of future technology and application of transcriptome analysis in a single cell are also discussed.

    Low-level laser therapy (LLLT) has been targeted as a promising approach that can mitigate post-infarction cardiac remodeling. There is some interesting evidence showing that the beneficial role of the LLLT could persist long-term even after the end of the application, but it remains to be systematically evaluated. Therefore, the present study aimed to test the hypothesis that LLLT beneficial effects in the early post-infarction cardiac remodeling could remain in overt heart failure even with the disruption of irradiations. Female Wistar rats were subjected to the coronary occlusion to induce myocardial infarction or Sham operation. A single LLLT application was carried out after 60 s and 3 days post-coronary occlusion, respectively. Echocardiography was performed 3 days and at the end of the experiment (5 weeks) to evaluate cardiac function. After the last echocardiographic examination, LV hemodynamic evaluation was performed at baseline and on sudden afterload increases. Compared with the Sham group, infarcted rats showed increased systolic and diastolic internal diameter as well as a depressed shortening fraction of LV. The only benefit of the LLLT was a higher shortening fraction after 3 days of infarction. However, treated-LLLT rats show a lower shortening fraction in the 5th week of study when compared with Sham and non-irradiated rats. A worsening of cardiac function was confirmed in the hemodynamic analysis as evidenced by the higher LV end-diastolic pressure and lower +dP/dt and -dP/dt with five weeks of study. Cardiac functional reserve was also impaired by infarction as evidenced by an attenuated response of stroke work index and cardiac output to a sudden afterload stress, without LLLT repercussions. No significant differences were found in the myocardial expression of Akt 1 /VEGF pathway. Collectively, these findings illustrate that LLLT improves LV systolic function in the early post-infarction cardiac remodeling. However, this beneficial effect may

Two levels of GABA, i.e., 0 mg L(-1) and 50 mg L(-1), in solution form, with total application volume of 100 ml per pot containing 15 maize seedlings were exogenously applied. Results revealed that exogenous GABA application improved seedling growth in terms of seedling length and biomass accumulation in all maize cultivars at both 3 and 7 days after treatment (DAT). It also promoted net photosynthesis and variably affected gas exchange attributes, i.e., stomatal conductance (Gs), intercellular CO2 concentration (Ci), and transpiration rate (Tr), as well as leaves SPAD value. Furthermore, lipid peroxidation [in terms of malondialdehyde (MDA)] under GABA treated maize seedlings were also remained variable; however, osmolyte accumulation (protein and proline) and activities of anti-oxidants enzymes, i.e., super-oxide dismutase and peroxidase were also affected differently at both 3 and 7 DAT in all maize cultivars. Furthermore, enzymes involved in nitrogen metabolism, e.g., nitrate reductase and glutamine synthetase were improved. These results suggest the involvement of GABA in various physio-metablical mechanisms which might lead to improvement in morphological growth of maize. In future, research is still needed at molecular and genetic levels to unravel the involvement of GABA-mediated regulations in growth and its associated physio-biochemical mechanisms.

    While recent evidence has indicated that experienced racial discrimination is associated with increased depressive symptoms for African American adolescents, most studies rely on cross-sectional and short-term longitudinal research designs. As a result, the direction and persistence of this association across time remains unclear. This article examines longitudinal associations between experienced racial discrimination and depressive symptoms among a community sample of African American adolescents (N = 504) from Grade 7 to Grade 10, while controlling for multiple alternative causal pathways. Sex was tested as a moderator of the link between experienced racial discrimination and later depressive symptoms. Structural equation modeling revealed that experienced racial discrimination was positively associated with depressive symptoms 1 year later across all waves of measurement. The link between experienced racial discrimination at Grade 7 and depressive symptoms at Grade 8 was stronger for females than males. Findings highlight the role of experienced racial discrimination in the etiology of depressive symptoms for African Americans across early adolescence. PMID:24188037

    Turns (pirouettes) are an important movement in ballet and may be affected by "lateral bias". This study investigated physiological differences exhibited by experienced and novice dancers, respectively, when performing pirouette with dominant and non-dominant leg supports, respectively. Thirteen novice and 13 experienced dancers performed turns on dominant or non-dominant legs. The maximum ankle plantarflexion, knee extension and hip extension were measured during the single-leg support phase. The inclination angle of rotation axis is the angle between instantaneous rotation axis and global vertical axis in the early single-leg support phase. Both groups exhibited a greater hip extension, knee extension, and ankle plantarflexion when performing a turn on the non-dominant leg. For experienced dancers, the inclination angle of rotation axis during the pre-swing phase was generally smaller for dominant leg support than non-dominant leg. However, no significant difference was found in inclination angle of rotation axis of novice dancers. For experienced dancers, an improved performance is obtained when using the dominant leg for support. By contrast, for novice dancers, the performance is independent of choice of support leg. The significant lateral bias in experienced dancers indicates the possible influence of training. That is, repetitive rehearsal on the preferred leg strengthens the impact of side dominance in experienced dancers.

    Experimental animal models of acute respiratory distress syndrome (ARDS) have shown that the updated airway pressure release ventilation (APRV) methodologies may significantly improve oxygenation, maximize lung recruitment, and attenuate lung injury, without circulatory depression. This led us to hypothesize that early application of APRV in patients with ARDS would allow pulmonary function to recover faster and would reduce the duration of mechanical ventilation as compared with low tidal volume lung protective ventilation (LTV). A total of 138 patients with ARDS who received mechanical ventilation for <48 h between May 2015 to October 2016 while in the critical care medicine unit (ICU) of the West China Hospital of Sichuan University were enrolled in the study. Patients were randomly assigned to receive APRV (n = 71) or LTV (n = 67). The settings for APRV were: high airway pressure (P high ) set at the last plateau airway pressure (P plat ), not to exceed 30 cmH 2 O) and low airway pressure ( P low ) set at 5 cmH 2 O; the release phase (T low ) setting adjusted to terminate the peak expiratory flow rate to ≥ 50%; release frequency of 10-14 cycles/min. The settings for LTV were: target tidal volume of 6 mL/kg of predicted body weight; P plat not exceeding 30 cmH 2 O; positive end-expiratory pressure (PEEP) guided by the PEEP-FiO 2 table according to the ARDSnet protocol. The primary outcome was the number of days without mechanical ventilation from enrollment to day 28. The secondary endpoints included oxygenation, P plat , respiratory system compliance, and patient outcomes. Compared with the LTV group, patients in the APRV group had a higher median number of ventilator-free days {19 [interquartile range (IQR) 8-22] vs. 2 (IQR 0-15); P < 0.001}. This finding was independent of the coexisting differences in chronic disease. The APRV group had a shorter stay in the ICU (P = 0.003). The ICU mortality rate was 19.7% in the APRV group versus 34.3% in the

    Out-of-hospital care is becoming more complex, thus placing greater reliance on the cognitive abilities of paramedics to manage difficult situations. In adapting to the challenges in their work, paramedics develop expertise. We study the cognitive strategies used by expert paramedics to contribute to understanding how paramedics and the EMS system can adapt to new challenges. We conducted a "staged-world" cognitive task analysis to explore paramedics' handling of cognitive challenges related to sense-making and to resource and task management. A mixed-fidelity simulation was used to present paramedics with 2 challenging scenarios: a pulmonary embolism initially presenting as a myocardial infarction and a 2-person shooting with limited resources available. Participants were 10 paramedics, 6 more experienced and 4 less experienced. Analysis involved comparing the performance of the 2 groups to identify strategies associated with expertise. The more experienced paramedics made more assessments, explored a wider variety of presumptive diagnoses, and identified the pulmonary embolism earlier. They switched attention between the 2 shooting victims more, used their emergency medical technician-basic level partners more, and provided more advanced level care for both patients. Their patients arrived at the emergency department more prepared for specialized emergency care. Our findings correspond to general cognitive attributes of expertise: greater cue gathering and inferential reasoning, and more functional and strategic thinking. These results suggest potential areas and methods to facilitate development of expertise, as well as ways to better support use of expertise. Future studies should expand on these findings through larger sample sizes and more complex scenarios. Copyright © 2013 American College of Emergency Physicians. Published by Mosby, Inc.

    2010-12-01

    The Famine Early Warning Systems Network (FEWS NET) has requirements for near real-time monitoring of vegetation conditions for food security applications. Accurate and timely assessments of crop conditions are an important element of food security decision making. FEWS NET scientists at the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center are utilizing a new Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) dataset for operational monitoring of crop and pasture conditions in parts of the world where food availability is highly dependent on subsistence agriculture and animal husbandry. The expedited MODIS, or eMODIS, production system processes NDVI data using MODIS surface reflectance provided by the Land Atmosphere Near-real-time Capability for EOS (LANCE). Benefits of this production system include customized compositing schedules, near real-time data availability, and minimized re-sampling. FEWS NET has implemented a 10-day compositing scheme every five days to accommodate the need for timely information on vegetation conditions. The data are currently being processed at 250-meter spatial resolution for Central America, Hispaniola, and Africa. Data are further enhanced by the application of a temporal smoothing filter which helps remove contamination due to clouds and other atmospheric effects. The results of this near real-time monitoring capability have been the timely provision of NDVI and NDVI anomaly maps for each of the FEWS NET monitoring regions and the availability of a consistently processed dataset to aid crop assessment missions and to facilitate customized analyses of crop production, drought, and agro-pastoral conditions.

  15. Experiencing the Implementation of New Inquiry Science Curricula

    NASA Astrophysics Data System (ADS)

    Ower, Peter S.

    Using a phenomenological methodology, a cohort of four experienced science teachers was interviewed about their experience transitioning from traditional, teacher and fact-centered science curricula to inquiry-based curricula. Each teacher participated in two interviews that focused on their teaching backgrounds, their experience teaching the prior traditional curriculum, and their experience teaching the new inquiry-based curriculum. The findings are presented as a narrative of each teachers' experience with the new curriculum implementation. Analyzing the data revealed four key themes. 1) The teachers felt trapped by the old curriculum as it did not align with their positive views of teaching science through inquiry. 2) The teachers found a way to fit their beliefs and values into the old and new curriculum. This required changes to the curriculum. 3) The teachers attempted to make the science curriculum as meaningful as possible for their students. 4) The teachers experienced a balancing act between their beliefs and values and the various aspects of the curriculum. The revealed essence of the curriculum transition is one of freedom and reconciliation of their beliefs. The teachers experienced the implementation of the new curriculum as a way to ensure their values and beliefs of science education were embedded therein. They treated the new curriculum as a malleable structure to impart their grander ideas of science education (e.g. providing important skills for future careers, creating a sense of wonder, future problem solving) to the students. Their changes were aligned with the philosophy of the curriculum kits they were implementing. Thus, the fidelity of the curriculum's philosophy was not at risk even though the curriculum kits were not taught as written. This study showed that phenomenological methods are able to reveal the relationship between a teacher's prior experiences, values and beliefs and their current instructional philosophy in science

    Theory and research from the marketing literature on customer-based brand equity were used to predict how positive exposure to 4 early recruitment-related activities-publicity, sponsorships, word-of-mouth endorsements, and advertising-may affect the application decisions of engineering students. Similar to prior marketing findings, the results suggested that early recruitment-related activities were indirectly related to intentions and decisions through 2 dimensions of employer brand image: general attitudes toward the company and perceived job attributes. The relationships between word-of-mouth endorsements and the 2 dimensions of brand image were particularly strong. In addition, it was found that early recruitment-related activities interacted with one another such that employer brand image was stronger when firms used publicity in conjunction with other early recruitment-related activities.

    Necrotic tissues within grape (Vitis vinifera) bunches represent an important source of Botrytis cinerea inoculum for Botrytis bunch rot (BBR) at harvest in vineyards. This research quantified the incidence of B. cinerea on necrotic floral and fruit tissues and the efficacy of biologically based treatments for suppression of B. cinerea secondary inoculum within developing bunches. At veraison (2009 and 2010), samples of aborted flowers, aborted fruits and calyptras were collected, and the incidence and sporulation of B. cinerea were determined. Aborted fruits presented significantly higher incidence in untreated samples. Early-season applications of Candida sake plus Fungicover®, Fungicover alone or Ulocladium oudemansii significantly reduced B. cinerea incidence on aborted flowers and calyptras by 46-85%. Chitosan treatment significantly reduced B. cinerea incidence on calyptras. None of the treatments reduced B. cinerea incidence on aborted fruits. Treatments significantly reduced sporulation severity by 48% or more. Treatments were effective at reducing B. cinerea secondary inoculum on necrotic tissues, in spite of the variable control on aborted fruits. This is the first report to quantify B. cinerea on several tissues of bunch trash and to describe the effective suppression of saprophytic B. cinerea inoculum by biologically based treatments. © 2013 Society of Chemical Industry.

    This study investigated the effect of nursing experience on attention allocation and task performance during surgery. The prevention of cases of retained foreign bodies after surgery typically depends on scrub nurses, who are responsible for performing multiple tasks that impose heavy demands on the nurses' cognitive resources. However, the relationship between the level of experiences and attention allocation strategies has not been extensively studied. Eye movement data were collected from 10 novice and 10 experienced scrub nurses in the operating theater for caesarean section surgeries. Visual scanning data, analyzed by dividing the workstation into four main areas and the surgery into four stages, were compared to the optimum expected value estimated by SEEV (Salience, Effort, Expectancy, and Value) model. Both experienced and novice nurses showed significant correlations to the optimal percentage dwell time values, and significant differences were found in attention allocation optimality between experienced and novice nurses, with experienced nurses adhering significantly more to the optimal in the stages of high workload. Experienced nurses spent less time on the final count and encountered fewer interruptions during the count than novices indicating better performance in task management, whereas novice nurses switched attention between areas of interest more than experienced nurses. The results provide empirical evidence of a relationship between the application of optimal visual attention management strategies and performance, opening up possibilities to the development of visual attention and interruption training for better performance.

  19. CyberShake-derived ground-motion prediction models for the Los Angeles region with application to earthquake early warning

    Real-time applications such as earthquake early warning (EEW) typically use empirical ground-motion prediction equations (GMPEs) along with event magnitude and source-to-site distances to estimate expected shaking levels. In this simplified approach, effects due to finite-fault geometry, directivity and site and basin response are often generalized, which may lead to a significant under- or overestimation of shaking from large earthquakes (M > 6.5) in some locations. For enhanced site-specific ground-motion predictions considering 3-D wave-propagation effects, we develop support vector regression (SVR) models from the SCEC CyberShake low-frequency (<0.5 Hz) and broad-band (0–10 Hz) data sets. CyberShake encompasses 3-D wave-propagation simulations of >415 000 finite-fault rupture scenarios (6.5 ≤ M ≤ 8.5) for southern California defined in UCERF 2.0. We use CyberShake to demonstrate the application of synthetic waveform data to EEW as a ‘proof of concept’, being aware that these simulations are not yet fully validated and might not appropriately sample the range of rupture uncertainty. Our regression models predict the maximum and the temporal evolution of instrumental intensity (MMI) at 71 selected test sites using only the hypocentre, magnitude and rupture ratio, which characterizes uni- and bilateral rupture propagation. Our regression approach is completely data-driven (where here the CyberShake simulations are considered data) and does not enforce pre-defined functional forms or dependencies among input parameters. The models were established from a subset (∼20 per cent) of CyberShake simulations, but can explain MMI values of all >400 k rupture scenarios with a standard deviation of about 0.4 intensity units. We apply our models to determine threshold magnitudes (and warning times) for various active faults in southern California that earthquakes need to exceed to cause at least ‘moderate’, ‘strong’ or ‘very strong’ shaking

    Elastic Light Scattering (ELS) is an innovative technique to identify bacterial pathogens directly on culture plates. Compelling results have already been reported for agri-food applications. Here, we have developed ELS for clinical diagnosis, starting with Staphylococcus aureus early screening. Our goal is to bring a result (positive/negative) after only 6 h of growth to fight surgical-site infections. The method starts with the acquisition of the scattering pattern arising from the interaction between a laser beam and a single bacterial colony growing on a culture medium. Then, the resulting image, considered as the bacterial species signature, is analyzed using statistical learning techniques. We present a custom optical setup able to target bacterial colonies with various sizes (30-500 microns). This system was used to collect a reference dataset of 38 strains of S. aureus and other Staphyloccocus species (5459 images) on ChromIDSAID/ MRSA bi-plates. A validation set from 20 patients has then been acquired and clinically-validated according to chromogenic enzymatic tests. The best correct-identification rate between S. aureus and S. non-aureus (94.7%) has been obtained using a support vector machine classifier trained on a combination of Fourier-Bessel moments and Local- Binary-Patterns extracted features. This statistical model applied to the validation set provided a sensitivity and a specificity of 90.0% and 56.9%, or alternatively, a positive predictive value of 47% and a negative predictive value of 93%. From a clinical point of view, the results head in the right direction and pave the way toward the WHO's requirements for rapid, low-cost, and automated diagnosis tools.

  1. Alkaliphilic Bacteria with Impact on Industrial Applications, Concepts of Early Life Forms, and Bioenergetics of ATP Synthesis

    2015-01-01

    Alkaliphilic bacteria typically grow well at pH 9, with the most extremophilic strains growing up to pH values as high as pH 12–13. Interest in extreme alkaliphiles arises because they are sources of useful, stable enzymes, and the cells themselves can be used for biotechnological and other applications at high pH. In addition, alkaline hydrothermal vents represent an early evolutionary niche for alkaliphiles and novel extreme alkaliphiles have also recently been found in alkaline serpentinizing sites. A third focus of interest in alkaliphiles is the challenge raised by the use of proton-coupled ATP synthases for oxidative phosphorylation by non-fermentative alkaliphiles. This creates a problem with respect to tenets of the chemiosmotic model that remains the core model for the bioenergetics of oxidative phosphorylation. Each of these facets of alkaliphilic bacteria will be discussed with a focus on extremely alkaliphilic Bacillus strains. These alkaliphilic bacteria have provided a cogent experimental system to probe adaptations that enable their growth and oxidative phosphorylation at high pH. Adaptations are clearly needed to enable secreted or partially exposed enzymes or protein complexes to function at the high external pH. Also, alkaliphiles must maintain a cytoplasmic pH that is significantly lower than the pH of the outside medium. This protects cytoplasmic components from an external pH that is alkaline enough to impair their stability or function. However, the pH gradient across the cytoplasmic membrane, with its orientation of more acidic inside than outside, is in the reverse of the productive orientation for bioenergetic work. The reversed gradient reduces the trans-membrane proton-motive force available to energize ATP synthesis. Multiple strategies are hypothesized to be involved in enabling alkaliphiles to circumvent the challenge of a low bulk proton-motive force energizing proton-coupled ATP synthesis at high pH.

    2016-04-01

    The current, budget-driven low rate of National Institutes of Health (NIH) funding for biomedical research has raised concerns about new investigators' ability to become independent scientists and their willingness to persist in efforts to secure funding. The authors sought to determine resubmission rates for unfunded National Heart, Lung, and Blood Institute (NHLBI) early stage investigator (ESI) independent research grant (R01) applications and to identify resubmission predictors. The authors used a retrospective cohort study design and retrieved applications submitted in fiscal years 2010-2012 from NIH electronic research administrative sources. They defined ESI applicants as those who have received no prior R01 (or equivalent) funding and are within 10 years of completion of their terminal research degree or medical residency training. ESI applications at the NHLBI were eligible for special funding consideration if they scored above, but within 10 points of, the payline. The primary outcome was application resubmission after failing to secure funding with the first R01 submission. Over half of the unfunded applications were resubmitted. Some of these were discussed and "percentiled." Among percentiled applications, the only significant predictor of resubmission was the percentile score. Over half (59%) of the ESI R01 grants funded by NHLBI in fiscal years 2010-2012 had percentile scores above but within 10 points of the NHLBI payline, and benefited from the special funding considerations. The only independent predictor of resubmission of NHLBI ESI R01 grant applications was percentile score; applicant demographics and institutional factors were not predictive of resubmission.

These properties of CO2 may cause it to leak upward, possibly contaminating underground sources of drinking water. We have participated in several multi-laboratory field experiments to investigate the chemical and isotopic parameters that are applicable to monitoring the flow of injected CO2 into deep saline aquifers and into potable shallow groundwater. Geochemical results from the deep SECARB Phase III tests at Cranfield oil field, Mississippi, and from the Frio Brine I and II pilots located in the S. Liberty oil field, Dayton, Texas, proved powerful tools in: 1- Tracking the successful injection and flow of CO2 into the injection sandstones; 2- showing major changes in the chemical (pH, alkalinity, and major divalent cations) and isotopic (δ13C values of CO2, and δ18O values of CO2 and brine) compositions of formation water; 3-. showing mobilization of metals, including Fe Mn and Pb, and organic compounds , including DOC, BTEX, PAHs, and phenols following CO2 injection; and 4- showing that some of the CO2 injected into the Frio "C" sandstone was detected in the overlying "B" sandstone that is separated from it by 15 m of shale and siltstone. Rapid, significant and systematic changes were also observed in the isotopic and chemical compositions of shallow groundwater at the Zero Emissions Research and Technology (ZERT) site located in Bozeman, Montana, in response to four yearly injections of variable amounts of CO2 gas through a slotted pipe placed horizontally at a depth of ~2 m below ground level. The observed changes, included the lowering of groundwater pH from ~7.0 to values as low as 5.6, increases in the alkalinity from about 400 mg/L as HCO3 to values of up to 1330 mg/L, increases in the electrical conductance from ~600 μS/cm to up to 1800 μS/cm, as well as increases in the concentrations of cations and metals

      The paper proposes a risk-based early warning considering characteristics of fracture-karst aquifer in North China and applied it in a super-large fracture-karst water source. Groundwater vulnerability, types of land use, water abundance, transmissivity and spatial temporal variation of groundwater quality were chosen as indexes of the method. Weights of factors were obtained by using AHP method based on relative importance of factors, maps of factors were zoned by GIS, early warning map was conducted based on extension theory with the help of GIS, ENVI+IDL. The early warning map fused five factors very well, serious and tremendous warning areas are mainly located in northwest and east with high or relatively high transmissivity and groundwater pollutant loading, and obviously deteriorated or deteriorated trend of petroleum. The early warning map warns people where more attention should be paid, and the paper guides decision making to take appropriate protection actions in different warning levels areas.

    To identify the frequency of psychological and emotional abuse, gender discrimination, verbal sexual harassment, physical sexual harassment, physical assault, and homophobia experienced by general internists. Cross-sectional survey. Canadian general internal medicine practices. The overall response rate was 70.6% (984/1,393); the 501 respondents who classified themselves as general internists were studied. Three-fourths of the internists experienced psychological and emotional abuse at the hands of patients, and 38% of the women and 26% of the men experienced physical assault by patients. The majority of the female internists experienced gender discrimination by patients (67%) and by physician peers (56%). Forty-five percent of the women experienced verbal sexual harassment by patients, and 22% experienced physical sexual harassment by patients. The male internists experienced verbal sexual harassment from nurses slightly more often than the female internists did (19% vs 13%, p > 0.05). Verbal sexual harassment by male colleagues was reported by 35% of the female internists, and physical sexual harassment was reported by 11%. Approximately 40% of general internists reported homophobic remarks by both health care team members and patients. Abuse, discrimination, and homophobia are prevalent in the internal medicine workplace. A direct, progressive, multidisciplinary approach is necessary to label and address these problems.

    The aim of this study consists of the application of an experimental protocol that allows information to be obtained about the visual search strategies elaborated by swimming coaches. 16 swimming coaches participated. The Experienced group (n=8) had 16.1 yr. (SD=8.2) of coaching experience and at least five years of experience in underwater vision. The Nonexperienced group in underwater vision (n= 8) had 4.2 yr. (SD= 4.0) of coaching experience. Participants were tested in a laboratory environment using a video-projected sample of the crawl stroke of an elite swimmer. This work discusses the main areas of the swimmer's body used by coaches to identify and analyse errors in technique from overhead and underwater perspectives. In front-underwater videos, body roll and mid-water were the locations of the display with higher percentages of fixation time. In the side-underwater slow videos, the upper body was the location with higher percentages of visual fixation time and was used to detect the low elbow fault. Side-overhead takes were not the best perspectives to pick up information directly about performance of the arms; coaches attended to the head as a reference for their visual search. The observation and technical analysis of the hands and arms were facilitated by an underwater perspective. Visual fixation on the elbow served as a reference to identify errors in the upper body. The side-underwater perspective may be an adequate way to identify correct knee angles in leg kicking and the alignment of a swimmer's body and leg actions.

    Little has been published in Colombia on HIV drug resistance in patients taking antiretroviral treatment (ART). Currently, the Colombian guidelines do not recommend the use of genotypic antiretroviral resistance tests (GART) for treatment-naive patients or for those experiencing a first therapeutic failure. To determine the frequency of relevant resistance mutations and the degree of susceptibility/ resistance of HIV to antiretroviral drugs (ARVs) in ART-experienced patients. A non-random sample of 170 ART-experienced HIV patients with virologic failure and who underwent GART was recruited. A study of HIV drug resistance was carried out in two groups of patients: one group that underwent early GART and the other group that received late GART testing. The most frequent type of resistance affected the non-nucleoside class (76%). The late-GART group had higher risk of nucleoside analog and protease inhibitor drug resistance, a higher number of resistance mutations and more complex mutational profiles than the early-GART group. A high cross resistance level (30%) was found in the nucleoside analog class. The least affected medications were tenofovir and darunavir. Our results suggest that performing GART late is associated with levels of ARV resistance that could restrict the use of an important number of essential ARV in subsequent regimens. There is a need to revise the current recommendations to include GART prior to start of treatment and after the first virologic failure.

    A big challenge in terms or landslide risk mitigation is represented by increasing the resiliency of society exposed to the risk. Among the possible strategies with which to reach this goal, there is the implementation of early warning systems. This paper describes a procedure to improve early warning activities in areas affected by high landslide risk, such as those classified as critical infrastructures for their central role in society. This research is part of the project LEWIS (Landslides Early Warning Integrated System): An Integrated System for Landslide Monitoring, Early Warning and Risk Mitigation along Lifelines. LEWIS is composed of a susceptibility assessment methodology providing information for single points and areal monitoring systems, a data transmission network and a data collecting and processing center (DCPC), where readings from all monitoring systems and mathematical models converge and which sets the basis for warning and intervention activities. The aim of this paper is to show how logistic issues linked to advanced monitoring techniques, such as big data transfer and storing, can be dealt with compatibly with an early warning system. Therefore, we focus on the interaction between an areal monitoring tool (a ground-based interferometric radar) and the DCPC. By converting complex data into ASCII strings and through appropriate data cropping and average, and by implementing an algorithm for line-of-sight correction, we managed to reduce the data daily output without compromising the capability for performing.

    The paper's aim is to compare experienced and potential US medical tourists' foreign health service-quality expectations. Data were collected via an online survey involving 1,588 US consumers engaging or expressing an interest in medical tourism. The sample included 219 experienced and 1,369 potential medical tourists. Respondents completed a SERVQUAL questionnaire. Mann-Whitney U-tests were used to determine significant differences between experienced and potential US medical tourists' service-quality expectations. For all five service-quality dimensions (tangibles, reliability, responsiveness, assurance and empathy) experienced medical tourists had significantly lower expectations than potential medical tourists. Experienced medical tourists also had significantly lower service-quality expectations than potential medical tourists for 11 individual SERVQUAL items. Results suggest using experience level to segment medical tourists. The study also has implications for managing medical tourist service-quality expectations at service delivery point and via external marketing communications. Managing medical tourists' service quality expectations is important since expectations can significantly influence choice processes, their experience and post-consumption behavior. This study is the first to compare experienced and potential US medical tourist service-quality expectations. The study establishes a foundation for future service-quality expectations research in the rapidly growing medical tourism industry.

    A study of disability among the indigenous Sami people in Norway presented a number of ethical and methodological challenges rarely addressed in the literature. The main study was designed to examine and understand the everyday life, transitions between life stages and democratic participation of Norwegian Sami people experiencing disability. Hence, the purpose of this article is to increase the understanding of possible ethical and methodological issues in research within this field. The article describes and discusses ethical and methodological issues that arose when conducting our study and identifies some strategies for addressing issues like these. The ethical and methodological issues addressed in the article are based on a qualitative study among indigenous Norwegian Sami people experiencing disability. The data in this study were collected through 31 semi-structured in-depth interviews with altogether 24 Sami people experiencing disability and 13 next of kin of Sami people experiencing disability (8 mothers, 2 fathers, 2 sister and 1 guardian). The researchers identified 4 main areas of ethical and methodological issues. We present these issues chronologically as they emerged in the research process: 1) concept of knowledge when designing the study, 2) gaining access, 3) data collection and 4) analysis and accountability. The knowledge generated from this study has the potential to benefit future health research, specifically of Norwegian Sami people experiencing disability, as well as health research concerning indigenous people in general, providing scientific-based insight into important ethical and methodological issues in research with indigenous people experiencing disability.

    High levels of experienced job autonomy are found to be beneficial for healthcare professionals and for the relationship with their patients. The aim of this study was to assess how maternity care professionals in the Netherlands perceive their job autonomy in the Dutch maternity care system and whether they expect a new system of integrated maternity care to affect their experienced job autonomy. A cross-sectional survey. The Leiden Quality of Work Life Questionnaire was used to assess experienced job autonomy among maternity care professionals. Data were collected in the Netherlands in 2015. 799 professionals participated of whom 362 were primary care midwives, 240 obstetricians, 93 clinical midwives and 104 obstetric nurses. The mean score for experienced job autonomy was highest for primary care midwives, followed by obstetricians, clinical midwives and obstetric nurses. Primary care midwives scored highest in expecting to lose their job autonomy in an integrated care system. There are significant differences in experienced job autonomy between maternity care professionals. When changing the maternity care system it will be a challenge to maintain a high level of experienced job autonomy for professionals. A decrease in job autonomy could lead to a reduction in job related wellbeing and in satisfaction with care among pregnant women. Copyright © 2017. Published by Elsevier Ltd.

    2018-06-01

    As one of the most serious meteorological disasters in modern society, air pollution has received extensive attention from both citizens and decision-makers. With the complexity of pollution components and the uncertainty of prediction, it is both critical and challenging to construct an effective and practical early-warning system. In this paper, a novel hybrid air quality early-warning system for pollution contaminant monitoring and analysis was proposed. To improve the efficiency of the system, an advanced attribute selection method based on fuzzy evaluation and rough set theory was developed to select the main pollution contaminants for cities. Moreover, a hybrid model composed of the theory of "decomposition and ensemble", an extreme learning machine and an advanced heuristic algorithm was developed for pollution contaminant prediction; it provides deterministic and interval forecasting for tackling the uncertainty of future air quality. Daily pollution contaminants of six major cities in China were selected as a dataset to evaluate the practicality and effectiveness of the developed air quality early-warning system. The superior experimental performance determined by the values of several error indexes illustrated that the proposed early-warning system was of great effectiveness and efficiency.

    2018-01-01

    The aim of this study is to understand the behaviors experienced nurse executives use to create healthy work environments (HWEs). The constructs of authentic leadership formed the conceptual framework for the study. The American Association of Critical-Care Nurses recommends authentic leadership as the preferred style of leadership for creating and sustaining HWEs. Behaviors associated with authentic leadership in nursing are not well understood. A purposive sample of 17 experienced nurse executives were recruited from across the United States for this qualitative study. Thematic analysis was used to analyze the in-depth, semistructured interviews. Four constructs of authentic leaders were supported and suggest unique applications of each including self-awareness (a private and professional self), balanced processing (open hearted), transparency (limiting exposure), and moral leadership (nursing compass). Authentic leadership may provide a sound foundation to support nursing leadership practices; however, its application to the discipline requires additional investigation.

    Background Volunteers in Taiwan complement the delivery of health services by paid health professionals. However, in doing so, community health volunteers experience burdens associated with their activities. The reasons for these burdens and degree to which they are experienced are explored in this paper. Our study adds to international research regarding the burden experienced by volunteers. This project is the first to assess how community health volunteers in Taiwan experience burden. Methods The 20 item Burden on Community Health Volunteer (BCHV) instrument, specifically designed for this project, was administered to 435 volunteers attached to Community Health Promotion Development Centres in northern Taiwan. Results The overall burden experienced by volunteers is relatively low. However, a multivariate adjusted regression analysis revealed significant differences in volunteer burden depending on the number of people each volunteer served on average per week, as well as the volunteer’s marital status and their perceptions about personal health. Volunteers who served many people and who perceived their own health as poor experienced a higher level of burden. Those who were a widow or a widower felt less burdened than others. Conclusions The results of the study identify areas where burden is high and where strategies can be developed to reduce the level of burden experienced by community health volunteers in Taiwan. Community health volunteers in Taiwan complement the role of nurses and other health care providers so their retention is important to ongoing service delivery. PMID:23687966

    Background Dengue outbreaks are increasing in frequency over space and time, affecting people’s health and burdening resource-constrained health systems. The ability to detect early emerging outbreaks is key to mounting an effective response. The early warning and response system (EWARS) is a toolkit that provides countries with early-warning systems for efficient and cost-effective local responses. EWARS uses outbreak and alarm indicators to derive prediction models that can be used prospectively to predict a forthcoming dengue outbreak at district level. Methods We report on the development of the EWARS tool, based on users’ recommendations into a convenient, user-friendly and reliable software aided by a user’s workbook and its field testing in 30 health districts in Brazil, Malaysia and Mexico. Findings 34 Health officers from the 30 study districts who had used the original EWARS for 7 to 10 months responded to a questionnaire with mainly open-ended questions. Qualitative content analysis showed that participants were generally satisfied with the tool but preferred open-access vs. commercial software. EWARS users also stated that the geographical unit should be the district, while access to meteorological information should be improved. These recommendations were incorporated into the second-generation EWARS-R, using the free R software, combined with recent surveillance data and resulted in higher sensitivities and positive predictive values of alarm signals compared to the first-generation EWARS. Currently the use of satellite data for meteorological information is being tested and a dashboard is being developed to increase user-friendliness of the tool. The inclusion of other Aedes borne viral diseases is under discussion. Conclusion EWARS is a pragmatic and useful tool for detecting imminent dengue outbreaks to trigger early response activities.

    Purpose Cephalomedullary nail (CM nail) in the treatment of femoral intertrochanteric fractures is in the lime light in recent years. The purpose of this study is to compare surgical outcomes between experienced surgeon and non-experienced surgeons in respect of CM nail for femoral intertrochanteric fractures. Materials and Methods The 129 patients underwent CM nail for femoral intertrochanteric fracture more than six months of follow-up from April 2011 to March 2014 in Seoul Medical Center (Seoul, Korea) were participated in this study. For this study, group A consisted of experienced surgeons who performed more than 500 times of CM nail, and group B consisted of non-experienced surgeons who performed less than 50 times of CM nail. Clinical and radiologic outcomes, complications and the need for reoperation between both groups were compared in the study. Results According to clinical result, both the mean operation time and transfusion volume were significantly longer and greater in group B (P<0.05). In the radiologic outcomes, adequacy of reduction, tip-apex distance and numbers of case placed in the Cleveland zones 5, 6 and 8; there was no statistical difference between both groups. Moreover, rate of complication and reoperation had same results as radiologic outcomes. Conclusion There was no significant difference with statistical data in complications from CM nail for femoral intertrochanteric fractures between experienced surgeon and non-experienced surgeon. Although the operation time and transfusion volume were significantly longer and greater in the case of operation by non-experienced surgeon, satisfactory performance was seen in the complications and the need for reoperation.

    The Kingdom of Saudi Arabia is one of the leading date producing countries. Unfortunately, this important fruit crop is under great threat from the red palm weevil (RPW) (Rhynchophorus ferrugineus), which is a highly invasive pest. Several techniques, including visual inspection, acoustic sensors, sniffer dogs, and pheromone traps have been tried to detect the early stages of a RPW infestation; however, each method has suffered certain logistical and implementation issues. We have applied laser induced breakdown spectroscopy (LIBS) for the early detection of RPW infestation. Through the analysis of the observed LIBS spectra of different infested and healthy samples, we have found presence of Ca, Mg, Na, C, K elements and OH, CN molecules. The spectra also reveal that with the population growth of the pest, the intensity of Mg and Ca atomic lines in LIBS spectra increases rapidly. Similar behavior is observed in the molecular lines of LIBS spectra. The obtained results indicate that the LIBS technique can be used for the early detection of RPW infestation without damaging the date palms.

The preventive application of juice of cone-flower herb or interferon in aggregate with vitamnin mineral complex statistically significantly decreases rate of respiratory infections and negligibly decreases direct and indirect costs of their treatment.

  20. How experiencing and anticipating temporal landmarks influence motivation.

    PubMed

    Dai, Hengchen; Li, Claire

    2018-04-30

    Temporal landmarks, or moments that stand out in time, structure people's perceptions and use of time. We highlight recent research examining how both experiencing and anticipating temporal landmarks impact motivation and goal pursuit. Experiencing a temporal landmark may produce a 'fresh start effect', making people feel more motivated to pursue their goals right after the landmark. Anticipating a future landmark may also increase people's current motivation if they are reminded of an ideal future state. We review one prominent explanation underlying these findings: temporal landmarks can create a psychological separation between past, current, and future selves. We also propose other possible explanations and discuss circumstances under which experiencing and anticipating temporal landmarks may cease to be motivating, or even harm motivation.

  1. Marketing actions can modulate neural representations of experienced pleasantness

    2008-01-01

    Despite the importance and pervasiveness of marketing, almost nothing is known about the neural mechanisms through which it affects decisions made by individuals. We propose that marketing actions, such as changes in the price of a product, can affect neural representations of experienced pleasantness. We tested this hypothesis by scanning human subjects using functional MRI while they tasted wines that, contrary to reality, they believed to be different and sold at different prices. Our results show that increasing the price of a wine increases subjective reports of flavor pleasantness as well as blood-oxygen-level-dependent activity in medial orbitofrontal cortex, an area that is widely thought to encode for experienced pleasantness during experiential tasks. The paper provides evidence for the ability of marketing actions to modulate neural correlates of experienced pleasantness and for the mechanisms through which the effect operates. PMID:18195362

    Despite the importance and pervasiveness of marketing, almost nothing is known about the neural mechanisms through which it affects decisions made by individuals. We propose that marketing actions, such as changes in the price of a product, can affect neural representations of experienced pleasantness. We tested this hypothesis by scanning human subjects using functional MRI while they tasted wines that, contrary to reality, they believed to be different and sold at different prices. Our results show that increasing the price of a wine increases subjective reports of flavor pleasantness as well as blood-oxygen-level-dependent activity in medial orbitofrontal cortex, an area that is widely thought to encode for experienced pleasantness during experiential tasks. The paper provides evidence for the ability of marketing actions to modulate neural correlates of experienced pleasantness and for the mechanisms through which the effect operates.

    This work sought to document how Indonesian trans* FtM persons experienced discrimination across the interlinked domains of social networks, religious and educational institutions, employment and the workplace, and health care institutions. Objectives were (1) to map the discrimination experienced by trans* FtM individuals in Indonesia, and (2) to establish the specific priorities of the Indonesian trans* FtM community. In-depth interviews, focus groups, and participant observation was used involving 14 respondents. Findings revealed that respondents experienced othering through rejection, misidentification, harassment, "correction," and bureaucratic discrimination across the five preestablished domains. Health care and a lack of information emerged as areas of particular concern for respondents. This work calls for health care that is sensitive to the needs of trans* FtM people coupled with high-quality information to alleviate the cycles through which discrimination is sustained.

    Environmental sound perception serves an important ecological function by providing listeners with information about objects and events in their immediate environment. Environmental sounds such as car horns, baby cries, or chirping birds can alert listeners to imminent dangers as well as contribute to one's sense of awareness and well being. Perception of environmental sounds as acoustically and semantically complex stimuli may also involve some factors common to the processing of speech. However, very limited research has investigated the abilities of cochlear implant (CI) patients to identify common environmental sounds, despite patients' general enthusiasm about them. This project (1) investigated the ability of patients with modern-day CIs to perceive environmental sounds, (2) explored associations among speech, environmental sounds, and basic auditory abilities, and (3) examined acoustic factors that might be involved in environmental sound perception. Seventeen experienced postlingually deafened CI patients participated in the study. Environmental sound perception was assessed with a large-item test composed of 40 sound sources, each represented by four different tokens. The relationship between speech and environmental sound perception and the role of working memory and some basic auditory abilities were examined based on patient performance on a battery of speech tests (HINT, CNC, and individual consonant and vowel tests), tests of basic auditory abilities (audiometric thresholds, gap detection, temporal pattern, and temporal order for tones tests), and a backward digit recall test. The results indicated substantially reduced ability to identify common environmental sounds in CI patients (45.3%). Except for vowels, all speech test scores significantly correlated with the environmental sound test scores: r = 0.73 for HINT in quiet, r = 0.69 for HINT in noise, r = 0.70 for CNC, r = 0.64 for consonants, and r = 0.48 for vowels. HINT and CNC scores in quiet

    Background Recently, rapid advances have been made in metabolomics-based, easy-to-use early cancer detection methods using blood samples. Among metabolites, profiling of plasma free amino acids (PFAAs) is a promising approach because PFAAs link all organ systems and have important roles in metabolism. Furthermore, PFAA profiles are known to be influenced by specific diseases, including cancers. Therefore, the purpose of the present study was to determine the characteristics of the PFAA profiles in cancer patients and the possibility of using this information for early detection. Methods and Findings Plasma samples were collected from approximately 200 patients from multiple institutes, each diagnosed with one of the following five types of cancer: lung, gastric, colorectal, breast, or prostate cancer. Patients were compared to gender- and age- matched controls also used in this study. The PFAA levels were measured using high-performance liquid chromatography (HPLC)–electrospray ionization (ESI)–mass spectrometry (MS). Univariate analysis revealed significant differences in the PFAA profiles between the controls and the patients with any of the five types of cancer listed above, even those with asymptomatic early-stage disease. Furthermore, multivariate analysis clearly discriminated the cancer patients from the controls in terms of the area under the receiver-operator characteristics curve (AUC of ROC >0.75 for each cancer), regardless of cancer stage. Because this study was designed as case-control study, further investigations, including model construction and validation using cohorts with larger sample sizes, are necessary to determine the usefulness of PFAA profiling. Conclusions These findings suggest that PFAA profiling has great potential for improving cancer screening and diagnosis and understanding disease pathogenesis. PFAA profiles can also be used to determine various disease diagnoses from a single blood sample, which involves a relatively simple

    To investigate the value of carbon nanoparticles in identifying sentinel lymph nodes in early-stage cervical cancer. From January 2014 to January 2016, 40 patients with cervical cancer stage IA2-IIA, based on the International Federation of Gynecology and Obstetrics (FIGO) 2009 criteria, were included in this study. The normal cervix around the tumor was injected with a total of 1 mL of carbon nanoparticles (CNP)at 3 and 9 o'clock. All patients then underwent laparoscopic pelvic lymph node dissection and radical hysterectomy. The black-dyed sentinel lymph nodes were removed for routine pathological examination and immunohistochemical staining. Among the 40 patients, 38 patients had at least one sentinel lymph node (SLN). The detection rate was 95% (38/40). One hundred seventy-three SLNs were detected with an average of 3.9 SLNs per side. 25 positive lymph nodes, which included 21 positive SLNs, were detected in 8 (20%) patients. Sentinel lymph nodes were localized in the obturator (47.97%), internal lilac (13.87%), external lilac (26.59%), parametrial (1.16%), and common iliac (8.67%) regions. The sensitivity of the SLN detection was 100% (5/5), the accuracy was 97.37% (37/38), and the negative predictive value was 100. 0% and the false negative rate was 0%. Sentinel lymph nodes can be used to accurately predict the pathological state of pelvic lymph nodes in early cervical cancer. The detection rates and accuracy of sentinel lymph node were high. Carbon nanoparticles can be used to trace the sentinel lymph node in early cervical cancer.

    Breeding of apple (Malus × domestica) remains a slow process because of protracted generation cycles. Shortening the juvenile phase to achieve the introgression of traits from wild species into prebreeding material within a reasonable time frame is a great challenge. In this study, we evaluated early flowering transgenic apple lines overexpressing the BpMADS4 gene of silver birch with regard to tree morphology in glasshouse conditions. Based on the results obtained, line T1190 was selected for further analysis and application to fast breeding. The DNA sequences flanking the T-DNA were isolated and the T-DNA integration site was mapped on linkage group 4. The inheritance and correctness of the T-DNA integration were confirmed after meiosis. A crossbred breeding programme was initiated by crossing T1190 with the fire blight-resistant wild species Malus fusca. Transgenic early flowering F(1) seedlings were selected and backcrossed with 'Regia' and 98/6-10 in order to introgress the apple scab Rvi2, Rvi4 and powdery mildew Pl-1, Pl-2 resistance genes and the fire blight resistance quantitative trait locus FB-F7 present in 'Regia'. Three transgenic BC'1 seedlings pyramiding Rvi2, Rvi4 and FB-F7, as well as three other BC'1 seedlings combining Pl-1 and Pl-2, were identified. Thus, the first transgenic early flowering-based apple breeding programme combined with marker-assisted selection was established. © 2011 The Authors. New Phytologist © 2011 New Phytologist Trust.

    A detailed description of flow cytofluorometric DNA cell cycle analysis is presented. A number of studies by the author and other investigators are reviewed in which a method is developed for the analysis of cell cycle phase in bone marrow of experimental animals. Bone marrow cell cycle analysis is a sensitive indicator of changes in bone marrow proliferative activity occurring early in chemically-induced myelotoxicity. Cell cycle analysis, used together with other hematologic methods, has revealed benzene-induced toxicity in proliferating bone marrow cells to be cycle specific, appearing to affect a population in late S phase which then accumulate in G2/M.

    Newly experienced events are often remembered together with how rewarding the experiences are personally. Although the hippocampus is a candidate structure where subjective values are integrated with other elements of episodic memory, it is uncertain whether and how the hippocampus processes value-related information. We examined how activity of dorsal CA1 and dorsal subicular neurons in rats performing a dynamic foraging task was related to reward values that were estimated using a reinforcement learning model. CA1 neurons carried significant signals related to action values before the animal revealed its choice behaviorally, indicating that the information on the expected values of potential choice outcomes was available in CA1. Moreover, after the outcome of the animal's goal choice was revealed, CA1 neurons carried robust signals for the value of chosen action and they temporally overlapped with the signals related to the animal's goal choice and its outcome, indicating that all the signals necessary to evaluate the outcome of an experienced event converged in CA1. On the other hand, value-related signals were substantially weaker in the subiculum. These results suggest a major role of CA1 in adding values to experienced events during episodic memory encoding. Given that CA1 neuronal activity is modulated by diverse attributes of an experienced event, CA1 might be a place where all the elements of episodic memory are integrated.

    This study aimed to evaluate the stigma and its correlates among patients with severe mental disorders. Patients with diagnosis of schizophrenia (N = 707), bipolar disorder (N = 344) and recurrent depressive disorder (N = 352) currently in clinical remission from 14 participating centres were assessed on Internalized Stigma of Mental Illness Scale (ISMIS). Patients with diagnosis of schizophrenia experienced higher level of alienation, sterotype endorsement, discrimination experience and total stigma when compared to patients with bipolar disorder and recurrent depressive disorder. Patients with bipolar disorder experienced higher stigma than those with recurrent depressive disorder in the domain of stigma resistance only. Overall compared to affective disorder groups, higher proportion of patients with schizophrenia reported stigma in all the domains of ISMIS. In general in all the 3 diagnostic groups' stigma was associated with shorter duration of illness, shorter duration of treatment and younger age of onset. To conclude, this study suggests that compared to affective disorder, patients with schizophrenia experience higher self stigma. Higher level of stigma is experienced during the early phase of illness. Stigma intervention programs must focus on patients during the initial phase of illness in order to reduce the negative consequences of stigma. Copyright © 2017 Elsevier B.V. All rights reserved.

    This study investigated the different postural control strategies exhibited by experienced and novice dancers in ballet turns (pirouettes). Thirteen novice and 13 experienced dancers performed ballet turns with dominant-leg support. The peak push force was measured in the double-leg support phase. The inclination angles of rotation axis with respect to vertical axis were calculated in the early single-leg support phase as well as the initiation sequence of ankle, knee, and hip joints on the supporting leg. Moreover, the anchoring index of the head was computed in the transverse plane during turning. The novice dancers applied a greater push force, an increased inclination angle of rotation axis, and an insufficient proximal-to-distal extension sequence pattern. The novice dancers also had a smaller head-anchoring index compared with experienced dancers, which meant novice dancers were not using a space target as a stability reference. A poorer performance in novice dancers could result from higher push force in propulsion, lack of a "proximal-to-distal extension sequence" pattern, and lack of visual spotting for postural stability. Training on sequential initiation of lower-extremity joints and rehearsal of visual spotting are essential for novice dancers to obtain better performance on ballet turns.

    Studies on factors associated with nutrition practices in early care and education settings often focus on sociodemographic and programmatic characteristics. This qualitative study adapted and applied Belsky's determinants of parenting model to inform a broader exploration of Early Care and Education Teachers (ECETs) practices. Qualitative cross-sectional study with ECETs. The researchers interviewed ECETs in their communities across a Southern state. Purposive sampling was employed to recruit ECETs (n = 28) from Head Start or state-funded centers serving low-income families. Developmental histories of ECETs regarding food and nutrition, beliefs about child nutrition, and teaching interactions related to food. Qualitative interviews were coded using a deductive content analysis approach. Three distinct interrelationships were observed across the themes. First, rules and routines regarding food and mealtime in the educators' childhood often aligned with educator beliefs and behaviors at meals in their classroom. Second, some ECETs described motivations to leave a healthy food legacy for children in their class. Finally, an experience of food insecurity appeared in narratives that also emphasized making sure children got enough through various strategies. The influence of ECET developmental histories and their related beliefs can be addressed through professional development and ongoing support. Future study should quantify model constructs in a larger sample and study their relationships over time. Copyright © 2017 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

    2015-01-01

    This study explored professional characteristics of psychotherapists in Turkey, examined the changes in their professional developmental processes, and compared the professional characteristics of the trainees and experienced therapists. The participants were 88 psychotherapists, including trainee (N=37) and experienced (N=51) psychotherapists in Turkey. They completed the Development of Psychotherapists International Study-Common Core Questionnaire (DPCCQ), developed by the Collaborative Research Network. The participants identified with the cognitive theoretical orientation most often. 30% of the participants had more than two salient orientations. The most prevalent therapy modality was individual, followed by couples, family, and group psychotherapy. Ongoing supervision rate was 44%. Trainees scored lower on effectiveness in engaging patients in a working alliance, feeling natural while working with patients, effectiveness in communicating their understanding and concern to their patients, and feeling confident in their role as a therapist. Experienced therapists made changes in the therapeutic contract and invited collaboration from families more compared to the trainees. 63% of the variance in Healing Involvement was explained by Overall Career Development, Currently Experienced Growth, being influenced by the humanistic approach, and the impact of the main therapeutic environment; 26% of the variance in Stressful Involvement was explained by the length of official supervision received and having control over the length of therapy sessions. Therapists were more cognitively oriented, less eclectic, and had less supervision compared to their international counterparts. Experienced therapists were more flexible, natural, and confident than the trainees. Supervision, a supportive work environment, the humanistic approach, and investing in career development were essential to providing a healing experience.

    To examine the extent and source of occupational violence and aggression (OVA) experienced by nursing and caring professionals. This study also examines the relative contributions of demographic characteristics and workplace and individual safety factors in predicting OVA. A cross-sectional study design with data collected using an online survey of employees in the nursing and caring professions in Victoria, Australia. Survey data collected from 4,891 members of the Australian Nursing and Midwifery Federation (Victorian branch) were analyzed using logistic regression. Sixty-seven percent of respondents reported experiencing OVA in the preceding 12 months, with nearly 20% experiencing OVA on a weekly or daily basis. The dominant sources of OVA were patients (79%) or relatives of patients (48%). Logistic regression analysis revealed that respondents working in public hospitals and aged care facilities were more likely to experience OVA, compared to those working in other workplaces. While higher levels of safety compliance reduced the likelihood of experiencing OVA, role overload and workplace safety factors such as prioritization of employee safety and leading indicators of occupational health and safety were stronger predictors. The likelihood of healthcare workers experiencing OVA varies across demographic and workplace characteristics. While some demographic characteristics and individual safety factors were significant predictors, our results suggest that a greater reduction in OVA could be achieved by improving workplace safety. The study's outcomes identify workforce segments that are most vulnerable to OVA. The study also highlights workplace safety factors such as the prioritization of employee safety that might assist in the reduction of OVA. © 2016 Sigma Theta Tau International.

    While there is a growing body of research on intimate partner violence (IPV) experienced by the housed youth population, a limited amount is known about IPV experienced by homeless youth. To our knowledge, no previous studies have examined how homeless youths’ experience of IPV is related to their social network, even though the social networks of homeless youth have been shown to be significant indicators of health and mental health. The purpose of this study is to understand the relationship between IPV, gender, and social networks among a sample of 386 homeless youth in Los Angeles, California. Results revealed that one fifth of the sample experienced IPV in the past year. Stratified regression models revealed that IPV was not significantly related to any measure of male social networks; however, females who experienced IPV had more male friends (β = 2.03, SE = 0.89, p < .05) than females who did not experience IPV. Female homeless youth who witnessed family violence during childhood had more male friends (β = 2.75, SE = 1.08, p < .05), but those who experienced sexual abuse during childhood had fewer male friends (β = −2.04, SE = 0.93, p < .05). Although there was no significant difference in the rate of IPV victimization across genders, the context of this abuse appears to be drastically different. The results suggest that females with more male friendships are at greater risk for exposure to IPV. To date, there are few effective youth-targeted IPV prevention programs and none have been shown to be effective with homeless youth. These results provide insight into future program development.

    The Great Lakes of the United States - the largest freshwater system in the world - have been termed "the canary in the coal mine" of environmental change. To assess if and how residents of Alger County, Michigan are experiencing changes in climate on the shores of Lake Superior, during the summer of 2010 we conducted a representative household mail survey in collaboration with a national lakeshore and watershed partnership. A total of 765 adult residents (18 years or older) responded to the survey; a 57% survey completion rate. We content analyzed respondents' open-ended characterizations of how they have personally experienced global warming, and compared the results with land surface and storm data for the same geographic region to see whether public perceptions of local changes match trends in National Climatic Data Center data. Just over a quarter of residents (27%) indicated that they had personally experienced global warming. Those who had were most likely to say that they had experienced global warming locally (as opposed to in other locations of the country or globally), and most frequently cited changes in seasons, weather, lake levels, and animals or plant species. However, some local public perceptions appeared to conflict with weather records. For example, residents were more likely to say that they had been experiencing less snow in the winters, while NCDC data suggests the reverse is true. As climate changes differentially in regions across the United States, the public will in turn experience its physical impacts in distinct ways that are unique to each landscape. This may be counter-intuitive to a public that increasingly experiences the world, and issues such as climate change, through sources of information such as national news media that operate at much larger geographic scales. Understanding where these forms of cognitive dissonance may arise may assist researchers, educators, and communicators in furthering discourses with the public about

    Background and Aims: Post-operative vomiting (POV) in children remains a significant clinical problem. This prospective study aims to investigate the applicability of well-established adult early post-operative nausea and vomiting (PONV) risk factors on paediatric POV after adenotonsillectomies under regulated anaesthetic conditions. Methods: After Institutional Review Board approval, 213 children aged 3–10-year-old were enrolled. The participants had pre-operative questionnaires completed, followed protocolised anaesthetic plans and had saliva analysed for cotinine. The primary outcomes were POV as correlated with age, gender, family or personal history of PONV, motion sickness history, opioid use, surgical time, anaesthetic time and environmental tobacco smoke (ETS) exposure, as assessed by cotinine levels and questionnaire reports. Data on analgesics, antiemetics and POV incidence before post-anaesthesia care unit discharge were collected. Statistical analysis was done through multiple logistic regression. Results: A total of 200 patients finalised the study. Early POV occurred in 32%. Family history of PONV (odds ratio [OR] = 5.3, P < 0.01) and motion sickness history (OR = 4.4, P = 0.02) were highly significant risk factors. Age reached borderline statistical significance (OR = 1.4, P = 0.05). None of the other factors reached statistical significance. Conclusion: Early POV occurs frequently in paediatric patients undergoing adenotonsillectomies. In this paediatric-aged group, the incidence of POV was affected by the family history of PONV, and history of motion sickness. Age, female gender, opioid use, surgical and anaesthetic times did not affect the incidence of POV. ETS exposure, as assessed by cotinine levels and questionnaire reports, had no protective effect on early paediatric POV. PMID:29307901

    Asia is the most vulnerable region in the world to hydro-meteorological extreme events, exacerbated by climate variability and change. Impacts of floods have been on the rapid increase in the recent decades. Myanmar is one of the most vulnerable countries in the lower Mekong region due to its socioeconomic situation (eg; Nargis in 2008, monsoon floods in 2015, etc). Early warning is an effective way to prepare for hydro-meteorological hazards, to minimize disaster risks; however, early warning systems in Myanmar are seriously hampered by limited observation networks. The Virtual Rain and Stream Gauge Information Service (VRSGIS) has been developed by SERVIR-Mekong program of Asian Disaster Preparedness Center (ADPC) to address these gaps and to provide dense, satellite-based rainfall and water level data, which are calibrated and validated with available in-situ observations. This service would enhance decision making in lower Mekong countries, including Myanmar, to minimize impacts of impending disasters. This service contains rainfall data from GPM IMERG and GSMap, CMORPH, TRMM, and CHIRPS, and water levels for 15 locations using Jason-2/3 altimetry. The virtual daily rainfall data sets are being calibrated with Gamma distribution method and are made publicly accessible through a user-friendly web interface.This paper presents a case study of satellite-derived rainfall data accessed from VRSGIS for hydrological modeling in Myanmar, to estimate inundation areas in Kalay township area of Chindwin River basin during the country's worst flood in 2015. Twelve out of fourteen States of Myanmar were severely affected, 103 people were killed, and one million were displaced due to heavy rains associated with Komen cyclone. The aforementioned rainfall data products are used as inputs for HEC-HMS hydrological runoff model to calculate river flows along Chindwin River, and HEC-RAS hydraulic model is used to estimate inundation areas in downstream including Kalay township

    Transradial coronary intervention (TRI) introduces injury to the radial artery (RA) which will affect repeat transradial coronary procedure and the quality as a bypass conduit. We sought to compare the early radial injury after TRI between first-TRI and repeat-TRI by ultrasound biomicroscopy (UBM). A total of 1116 patients who underwent the transradial coronary procedures were enrolled. The patients depending on whether for the first time to accept transradial coronary procedure were divided into first-TRI group and repeat-TRI group. The RA was examined by UBM before and one day after the procedure. Compared with first-TRI group, the mean RA diameter of repeat-TRI one day after the procedure decreased significantly (P < 0.05). In first-TRI group, the mean RA diameter was (2.32 ± 0.53) and (1.93 ± 0.57) mm before procedure and one day after the procedure respectively (P < 0.05). In repeat-TRI group, the mean RA diameter was (2.37 ± 0.51) and (1.79 ± 0.54) mm before procedure and one day after the procedure, respectively (P < 0.01). Compared with first-TRI group, the mean RA diameter was reduced significantly in repeat-TRI group one day after the procedure (P < 0.05). The early radial injuries and intimal thickening were compared between first-TRI and repeat-TRI. The mean intima-media thickness of RA was (0.24 ± 0.13) mm and (0.59 ± 0.28) mm before procedure and one day after the procedure in first-TRI group. The mean intima-media thickness of RA was (0.29 ± 0.16) mm and (0.68 ± 0.32) mm before procedure and one day after the procedure in repeat-TRI group. Compared with first-TRI group, the mean intimal thickening was increased significantly in repeat-TRI group one day after the procedure (P < 0.05). Intimal dissection, stenosis and occlusion were all significantly greater in repeat-TRI RAs (P < 0.05). Linear regression analysis revealed that diameter, repeated TRI procedure and PCI procedure were the independent predictors of intimal thickening. RA early

    Recent studies have cast doubt on the unadjusted usage of Jurassic and Cretaceous δ 18O paleotemperature data derived from belemnites, since the latter data often reflect cooler paleotemperature estimates than would be expected. In this study we address this problem by analysing rocks of Barremian to early Aptian age from two outcrops in northern Germany using TEX 86 paleothermometry, along with 142 belemnite guards studied for their stable isotope (δ 13C, δ 18O) and trace element composition (magnesium, strontium, iron, and manganese). Both TEX 86 and δ 18O Bel indicate very warm water temperatures for a distinctive black shale sequence of late early Barremian age ("Hauptblätterton") with temperatures of up to 29 °C and 23 °C, respectively. We observe a constant offset of TEX 86 temperatures versus the 4 to 5 °C cooler δ 18O belemnite signal for this interval. The late Barremian sequence shows an increase of the δ 18O Bel values from - 1‰ to 0‰ reflecting temperatures around 16 to 12 °C, while the contemporaneous TEX 86 temperatures vary between 26 and 32 °C. The common occurrence of belemnites in the anoxic sediments of the early Barremian implies, however, clearly a nektonic way of life similar to that of recent teuthids, rather than a nektobenthic one like Sepia. This in turn suggests that the belemnites investigated here (genera Praeoxyteuthis, Aulacoteuthis, Oxyteuthis, and Neohibolites) were active swimmers, which inhabited a deeper habitat below the thermocline in an epicontinental sea of perhaps 100 to 250 m water depth. The offset of the TEX 86 and δ 18O Bel data is therefore interpreted to reflect temperature signals from two different depth habitats, i.e. the TEX 86 is selectively derived from warm sea-surface waters, and the belemnites likely occupied deeper and cooler waters with relative increasing salinities in the late Barremian. This study stresses the importance that the taxonomy, paleobiology and ecology of the belemnite taxa

    Technology-based interventions for Autism Spectrum Disorder (ASD) have proliferated, but few have been evaluated within the context of a randomised controlled trial (RCT). This RCT evaluated the efficacy of one technology-based early intervention programme (Therapy Outcomes By You; TOBY) in young children with ASD. TOBY is an app-based learning curriculum designed for children and parents as a complement to early behavioural intervention. Eighty children (16 female) were recruited to this RCT within 12 months of receiving a diagnosis of ASD (M age = 3.38; SD = 0.69) and randomised to receive either treatment-as-usual (community-based intervention, n = 39) or the TOBY therapy (at least 20 min/day) plus treatment-as-usual (n = 41) for a period of 6 months. Outcomes were assessed at 3 and 6 months postbaseline. (Australian New Zealand Clinical Trials Registry: ACTRN12614000738628; www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=365463). Children in the TOBY intervention group averaged 19 min/day engaging with the app in the first 3 months, but only 2 min/day during the second 3 months. There was no group difference in scores on the primary outcome, the Autism Treatment Evaluation Checklist, at either the 3- or 6-month follow-up. However, significant improvements at the 6-month follow-up were observed in the TOBY intervention group relative to the treatment-as-usual group on three secondary outcomes: the Fine Motor and Visual Reception subscales of the Mullen Scale of Early Learning and the Total Words Understood scale of the MacArthur-Bates Communicative Development Index. Statistical trends towards improvement in the TOBY intervention group were observed on measures of adaptive function, although these decreased in magnitude from the 3- to 6-month follow-up. This study provides evidence that technology-based interventions may provide a relatively low-cost addition to existing therapist-delivered interventions for children with ASD. However

    1995-11-01

    The authors reviewed the literature to better understand pathways to psychiatric care among young persons experiencing a first episode of psychosis. Because no discrete body of literature exists about how young people with psychotic illness gain access to psychiatric services, the authors examined three related areas: illness recognition, help-seeking, and referral pathways. Automated and manual searches of primarily medical and psychological sources from 1977 to 1995 were conducted. The review found evidence of delay in obtaining early treatment among young people with an emerging psychosis, although comparisons between studies are difficult. Early psychiatric intervention is believed to significantly aid recovery and is an increasingly important clinical issue. Recognizing psychiatric illness is problematic for professionals and nonprofessionals. Understanding of help seeking by patients experiencing a first psychotic episode and of their referral pathways is limited. Taken together, studies suggest factors affecting access to treatment but provide neither sufficient empirical information nor an adequate conceptual framework to better target secondary prevention strategies. Formulation of a pathways-to-care model appears to offer a useful way of understanding mental health care use. Exploration of consumer experiences would enrich the model. Strategies to reduce treatment delay could then be developed and evaluated. Increased consumer involvement might help ensure that services are better tailored to patients' needs.

    Membrane bioreactors (MBRs) are the preferred technology for the preliminary treatment of Early Planetary Base Wastewater (EPBW) because of their compact configuration and promising treatment performance. For long-duration space missions, irreversible membrane biofouling resulting from the strong attachment of biomass and the formation of biofilms are major concerns for the MBR process. In this study, a MBR was operated for 230 days treating synthetic EPBW. The reactor demonstrated excellent treatment performance, in terms of chemical oxygen demand removal and nitrification. Filtration resistance is mainly caused by concentration polarization, reversible fouling, and irreversible fouling. Analysis of the microbial communities in the planktonic and corresponding sessile biomass suggested that the microbial community of the planktonic biomass was significantly different from the one of the sessile biomass. This study provides valuable information for the development of the water reuse component in the National Aeronautics and Space Administration's (Washington, D.C.) Advanced Life Support system for long-term space missions.

    While the ability to model the state of a space system over time is essential during spacecraft operations, the use of time-based simulations remains rare in preliminary design. The absence of the time dimension in most traditional early design tools can however become a hurdle when designing complex systems whose development and operations can be disrupted by various events, such as delays or failures. As the value delivered by a space system is highly affected by such events, exploring the trade space for designs that yield the maximum value calls for the explicit modeling of time.This paper discusses the use of discrete-event models to simulate spacecraft development schedule as well as operational scenarios and on-orbit resources in the presence of uncertainty. It illustrates how such simulations can be utilized to support trade studies, through the example of a tool developed for DARPA's F6 program to assist the design of "fractionated spacecraft".

    Objective: To evaluate the value of multi-parametric MRI (Mp-MRI) in the diagnosis and differential diagnosis of early prostate cancer(PCa) in the peripheral zone(PZ) and low T 2 WI signal intensity of prostatitis. Methods: A total of 40 patients with PZ early PCa and 37 with prostatitis of hypointense T 2 WI signal in PZ were retrospectively analyzed, which were collected from the General Hospital of Ningxia Medical University from Janurary 2009 to June 2015, who underwent T 2 WI, DWI, and DCE-MRI examination and all patients were confirmed by pathology. All the data was transferred to GE Advanced Workstation AW4.3, the indexes divided into cancerous and prostatitis regions were calculated by Functool2 of signal intensity-time(SI-T) curve and ADC value, to calcuate the time to minimum(T max ), the whole enhancment degree (SI max ). ROC cure was used to determine the cutoff value for PCa detection with the ADC value. Result: On T 2 WI, 57.5% of PCa (23/40) showed focal nodular homogeneous low signal intensity, 70.3% of prostatitis(26/37) showed diffuse inhomogeneous low signal intensity. DCE-MRI, the distribution of curve types for malignant tumors was type Ⅰ 2.5%(1/40), typeⅡ32.5%(13/40) and type Ⅲ 65.0% (26/40).

    Amniotic membrane (AM)-derived products have been successfully used in ophthalmology, plastic surgery, and wound care, but little is known about their potential applications in orthopaedic sports medicine. To provide an updated review of the basic science and preclinical and clinical data supporting the use of AM-derived products and to review their current applications in sports medicine. Systematic review. A systematic search of the literature was conducted using the Medline, EMBASE, and Cochrane databases. The search term amniotic membrane was used alone and in conjunction with stem cell, orthopaedic, tissue engineering, scaffold, and sports medicine. The search identified 6870 articles, 80 of which, after screening of the titles and abstracts, were considered relevant to this study. Fifty-five articles described the anatomy, basic science, and nonorthopaedic applications of AM-derived products. Twenty-five articles described preclinical and clinical trials of AM-derived products for orthopaedic sports medicine. Because the level of evidence obtained from this search was not adequate for systematic review or meta-analysis, a current concepts review on the anatomy, physiology, and clinical uses of AM-derived products is presented. Amniotic membranes have many promising applications in sports medicine. They are a source of pluripotent cells, highly organized collagen, antifibrotic and anti-inflammatory cytokines, immunomodulators, and matrix proteins. These properties may make it beneficial when applied as tissue engineering scaffolds, improving tissue organization in healing, and treatment of the arthritic joint. The current body of evidence in sports medicine is heavily biased toward in vitro and animal studies, with little to no human clinical data. Nonetheless, 14 companies or distributors offer commercial AM products. The preparation and formulation of these products alter their biological and mechanical properties, and a thorough understanding of these

    Previous studies have shown that observing another’s pain can evoke other-oriented emotions, which instigate empathic concern for another’s needs. It is not clear whether experiencing first-hand physical pain may also evoke other-oriented emotion and thus influence people’s moral judgment. Based on the embodied simulation literature and neuroimaging evidence, the present research tested the idea that participants who experienced physical pain would be more sympathetic in their moral judgments. Study 1 showed that ice-induced physical pain facilitated higher self-assessments of empathy, which motivated participants to be more sympathetic in their moral judgments. Study 2 confirmed findings in study 1 and also showed that State Perspective Taking subscale of the State Empathy Scale mediated the effects of physical pain on moral judgment. These results provide support for embodied view of morality and for the view that pain can serve a positive psychosocial function. PMID:26465603

    This study explored the perceptions of fatherhood held by 11 men living in a homeless shelter. Using consensual qualitative research methodology (CQR; Hill, 2012), we investigated perceptions of masculinity and fatherhood among fathers experiencing homelessness. Participants described (a) their perceptions of masculinity and fatherhood and changes resulting from homelessness, (b) physical and psychological challenges of being a father experiencing homelessness, and (c) expectations of homeless fathers. The fathers generally expressed feelings of low self-esteem related to their perceived difficulty fulfilling the role of providers for their family; however, they also adapted their view of fatherhood to include roles suited to their situation, such as that of guide, teacher, and role model. Suggestions are made for clinicians in helping fathers navigate and develop these roles, and limitations and directions for future research are discussed.

    The use of high performance systems, which is the trend of future space systems, naturally leads to lower margins and a higher sensitivity to parameter variations and, therefore, more problems of dynamical physical systems. To circumvent dynamic problems of these systems, appropriate design, verification analysis, and tests must be planned and conducted. The basic design goal is to define the problem before it occurs. The primary approach for meeting this goal is a good understanding and reviewing of the problems experienced in the past in terms of the system under design. This paper reviews many of the dynamic problems experienced in space systems design and operation, categorizes them as to causes, and envisions future program implications, developing recommendations for analysis and test approaches.

    Approximately 25% of hearing women in the United States experience rape in their life-time, whereas deaf women have been found to experience increased rates of assault consistent with other marginalized populations. This study explored sexual assault prevalence and characteristics of assault in deaf female undergraduate students. Results revealed that more than two-thirds of the participants (69%) endorsed experiencing at least one assault and more than half (56%) experienced multiple types of assault. Most assaults were committed by a man known to the survivor. Characteristics (e.g., hearing status, primary language, and ethnicity) of the survivors and the assailants are explored. The implications of this data are discussed as well as the development of culturally and linguistically sensitive outreach and educational programs.

    This descriptive study used a mailed survey to identify difficulties related to the stoma that ostomates experience after discharge from the hospital, who they sought help from, and if the advice was perceived as helpful. Ostomates who are 18 years or older and have undergone a urinary or fecal diversion at a North Carolina hospital between January 1, 2003 and June 30, 2005, were asked to respond to a survey about the difficulties related to their ostomy. The survey gathered demographic and anthropometric data, information regarding stomal complications, self-evaluation of emotional state, and contact with clinicians and support groups. Of the 140 surveys mailed, 43 were returned, demonstrating a return rate of 31%. Thirty-four returned surveys were useable for statistical analysis. The top 5 difficulties experienced by the respondents were peristomal skin irritation (76%), pouch leakage (62%), odor (59%), reduction in previously enjoyed activities (54%), and depression/anxiety (53%). Twenty percent of the ostomates who experienced difficulties after surgery did not seek help. Ostomates primarily sought help from nurses when they experienced problems related to the stoma and its maintenance. For mental health, sleep, and sexual problems, a medical doctor was the practitioner of choice. Ostomates were satisfied with most of the help they received from an ostomy nurse; satisfaction was lower for home health nurses and surgeon or primary care physician practices. Average wear time for a stoma pouch was 4 days. The majority of the ostomates experienced difficulty with pouch leakage, skin irritation, odor, depression or anxiety, and uneven pouching surfaces. Ostomates desire assistance with these problems and will benefit from long-term follow-up by an ostomy nurse.

    The high global food prices in 2008 led to the acknowledgement that there is a need to monitor the inter-connectivity of global and regional markets and their potential impacts on food security in many more regions than previously considered. The crisis prompted an expansion of monitoring by the Famine Early Warning Systems Network (FEWS NET) to include additional countries, beyond those where food security has long been of concern. Scientists at the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center and the University of California Santa Barbara Climate Hazards Group have provided new and improved data products as well as visualization and analysis tools in support of this increased mandate for remote monitoring. We present a new product for measuring actual evapotranspiration (ETa) based on the implementation of a surface energy balance model and site improvements of two standard FEWS NET monitoring products: normalized difference vegetation index (NDVI) and satellite-based rainfall estimates. USGS FEWS NET has implemented a simplified surface energy balance model to produce operational ETa anomalies for Africa. During the growing season, ETa anomalies express surplus or deficit crop water use which is directly related to crop condition and biomass. The expedited Moderate Resolution Imaging Spectroradiometer (eMODIS) production system provides FEWS NET with a much improved NDVI dataset for crop and rangeland monitoring. eMODIS NDVI provides a reliable data stream with a vastly improved spatial resolution (250-m) and short latency period (less than 12 hours) which allows for better operational vegetation monitoring. FEWS NET uses satellite rainfall estimates as inputs for monitoring agricultural food production. By combining high resolution (0.05 deg) rainfall mean fields with Tropical Rainfall Measuring Mission rainfall estimates and infrared temperature data, we provide pentadal (5-day) rainfall fields suitable for crop

    Archean hydrothermal environments formed a likely site for the origin and early evolution of life. These are also the settings, however, were complex abiologic structures can form. Low-temperature serpentinization of ultramafic crust can generate alkaline, silica-saturated fluids in which carbonate-silica crystalline aggregates with life-like morphologies can self-assemble. These "biomorphs" could have adsorbed hydrocarbons from Fischer-Tropsch type synthesis processes, leading to metamorphosed structures that resemble carbonaceous microfossils. Although this abiogenic process has been extensively cited in the literature and has generated important controversy, so far only one specific biomorph type with a filamentous shape has been discussed for the interpretation of Archean microfossils. It is therefore critical to precisely determine the full distribution in morphology and size of these biomorphs, and to study the range of plausible geochemical conditions under which these microstructures can form. Here, a set of witherite-silica biomorph synthesis experiments in silica-saturated solutions is presented, for a range of pH values (from 9 to 11.5) and barium ion concentrations (from 0.6 to 40 mmol/L BaCl 2 ). Under these varying conditions, a wide range of life-like structures is found, from fractal dendrites to complex shapes with continuous curvature. The size, spatial concentration, and morphology of the biomorphs are strongly controlled by environmental parameters, among which pH is the most important. This potentially limits the diversity of environments in which the growth of biomorphs could have occurred on Early Earth. Given the variety of the observed biomorph morphologies, our results show that the morphology of an individual microstructure is a poor criterion for biogenicity. However, biomorphs may be distinguished from actual populations of cellular microfossils by their wide, unimodal size distribution. Biomorphs grown by diffusion in silica gel can

    Our goal was to explore the meaning experienced psychotherapists derive from providing psychotherapy, their beliefs about the role of meaning in life (MIL) in psychotherapy, how they worked with MIL with a client who explicitly presented concerns about MIL, and how they worked with a different client for whom MIL was a secondary and more implicit concern. Thirteen experienced psychotherapists were interviewed and data were analyzed using consensual qualitative research. Therapists derived self-oriented meaning (e.g., feeling gratified, fulfilled, connected) and other-oriented meaning (helping others, making the world a better place) from providing psychotherapy. They believed that MIL is fundamental and underlies all human concerns, including those brought to therapy. In contrast to the clients who had implicit MIL concerns, clients who explicitly presented MIL concerns were reported to have more interpersonal problems and physical problems, but about the same amount of psychological distress and loss/grief. Therapists used insight-oriented interventions, support, action-oriented interventions, and exploratory interventions to work with MIL with both types of clients, but used more exploratory interventions with implicit than explicit MIL clients. MIL is a salient topic for experienced, existentially oriented psychotherapists; they work with MIL extensively with some clients in psychotherapy. We recommend that therapists receive training to work with MIL in therapy, and that they pay attention to MIL concerns when they conduct psychotherapy. We also recommend additional research on MIL in psychotherapy.

    The purpose of this research is to describe the thinking process of students who experienced pseudo thinking when solving the straight line equation. The result of this study shows the characteristics of error that caused students to experience pseudo thinking when solving the problem and their relation with students’ metacognition skill. This qualitative research was conducted in State 16 Junior High School in Surakarta, Indonesia during the odd semester of 2017/2018 academic year. The subjects of the study were students Junior High School students of 8th grade chosen using purposive sampling technique. Data were collected through the administration of think aloud method. The result showed that the characteristics of errors among the subjects are: 1) the answers resulted from pseudo thinking when solving the problem were obtained from the spontaneous, fast, unconscious and uncontrolled thinking process; 2) students had misconception; 3) students had tendency to memorize the formula and imitate the completion procedure; 4) students experienced fuzzy memory when solving the problem. From the mistakes among students who experienced pseudo thinking, their metacognition ability could be inferred.

    Ensemble docking is now commonly used in early-stage in silico drug discovery and can be used to attack difficult problems such as finding lead compounds which can disrupt protein-protein interactions. We give an example of this methodology here, as applied to fibroblast growth factor 23 (FGF23), a protein hormone that is responsible for regulating phosphate homeostasis. The first small-molecule antagonists of FGF23 were recently discovered by combining ensemble docking with extensive experimental target validation data (Science Signaling, 9, 2016, ra113). Here, we provide a detailed account of how ensemble-based high-throughput virtual screening was used to identify the antagonist compounds discovered in reference (Science Signaling, 9, 2016, ra113). Moreover, we perform further calculations, redocking those antagonist compounds identified in reference (Science Signaling, 9, 2016, ra113) that performed well on drug-likeness filters, to predict possible binding regions. These predicted binding modes are rescored with the molecular mechanics Poisson-Boltzmann surface area (MM/PBSA) approach to calculate the most likely binding site. Our findings suggest that the antagonist compounds antagonize FGF23 through the disruption of protein-protein interactions between FGF23 and fibroblast growth factor receptor (FGFR). © 2017 John Wiley & Sons A/S.

    During meiotic prophase I, chromatin undergoes dynamic changes to establish a structural basis for essential meiotic events. However, the mechanism that coordinates chromosome structure and meiotic progression remains poorly understood in plants. Here, we characterized a spontaneous sterile mutant MS5bMS5b in oilseed rape (Brassica napus) and found its meiotic chromosomes were arrested at leptotene. MS5 is preferentially expressed in reproductive organs and encodes a Brassica-specific protein carrying conserved coiled-coil and DUF626 domains with unknown function. MS5 is essential for pairing of homologs in meiosis, but not necessary for the initiation of DNA double-strand breaks. The distribution of the axis element-associated protein ASY1 occurs independently of MS5, but localization of the meiotic cohesion subunit SYN1 requires functional MS5. Furthermore, both the central element of the synaptonemal complex and the recombination element do not properly form in MS5bMS5b mutants. Our results demonstrate that MS5 participates in progression of meiosis during early prophase I and its allelic variants lead to differences in fertility, which may provide a promising strategy for pollination control for heterosis breeding.

    Medicine packages can cause problems in daily practice, especially among older people. This study aimed to investigate the prevalence of problems experienced by older people when opening medicine packaging and to investigate how patients manage these problems. A convenience sample of 30 community pharmacies participated in this study. They selected a systematic sample of 30 patients over 65 years old with a recent omeprazole prescription, and a questionnaire was administered by telephone for at least 10 patients per pharmacy. A total of 317 patients completed the questionnaire. They received their omeprazole in a bottle (n = 179, 56.5%), push-through blister pack (n = 102, 32.2%) or peel-off blister pack (n = 36, 11.4%). Some 28.4% of all patients experienced one or more problems with opening their omeprazole packaging; most problems occurred with peel-off blisters (n = 24, 66.7% of all respondents using peel-off blisters), followed by push-through blisters (n = 34, 33.3%) and finally bottles (n = 32, 17.9%). The risk of experiencing problems with peel-off blisters and push-through blisters was higher [relative risk 3.7 (95% confidence interval 2.5-5.5) and 1.9 (1.2-2.8), respectively] than the risk of experiencing problems with opening bottles. Two-thirds of respondents reported management strategies for their problems. Most were found for problems opening bottles (n = 24, 75%), followed by push-through blisters (n = 24, 70.6%) and peel-off blisters (n = 14, 58.3%). One in four patients over 65 experienced difficulties opening their omeprazole packaging and not all of them reported a management strategy for their problems. Manufacturers are advised to pay more attention to the user-friendliness of product packaging. In addition, it is important that pharmacy staff clearly instruct patients on how to open their medicine packaging, or assist them in choosing the most appropriate packaging. © 2013 Royal Pharmaceutical Society.

    Accelerated partial breast irradiation (APBI) is an accepted treatment option in breast-conserving therapy for early stage breast cancer. However, data regarding outcomes of patients treated with multi-lumen catheter systems who have existing breast implants is limited. The purpose of this study was to report treatment parameters, outcomes, and possible dosimetric correlation with cosmetic outcome for this population of patients at our institution. We report the treatment and outcome of seven consecutive patients with existing breast implants and early stage breast cancer who were treated between 2009 and 2013 using APBI following lumpectomy. All patients were treated twice per day for five days to a total dose of 34 Gy using a high-dose-rate (192)Ir source. Cosmetic outcomes were evaluated using the Harvard breast cosmesis scale, and late toxicities were reported using the Radiation Therapy Oncology Group (RTOG) late radiation morbidity schema. After a mean follow-up of 32 months, all patients have remained cancer free. Six out of seven patients had an excellent or good cosmetic outcome. There were no grade 3 or 4 late toxicities. The average total breast implant volume was 279.3 cc, received an average mean dose of 12.1 Gy, and a maximum dose of 234.1 Gy. The average percentage of breast implant volume receiving 50%, 75%, 100%, 150%, and 200% of the prescribed dose was 15.6%, 7.03%, 4.6%, 1.58%, and 0.46%, respectively. Absolute volume of breast implants receiving more than 50% of prescribed dose correlated with worse cosmetic outcomes. Accelerated partial breast irradiation using a multi-lumen applicator in patients with existing breast implants can safely be performed with promising early clinical results. The presence of the implant did not compromise the ability to achieve dosimetric criteria; however, dose to the implant and the irradiated implant volume may be related with worse cosmetic outcomes.

    Shock recovery experiments on suspensions of 106 mm-3 E. coli bacteria contained in water-based medium, within stainless steel containers, are used to simulate the impact environment of bacteria residing in water-filled cracks in rocks. Early Earth life is likely to have existed in such environments. Some 10-2 to 10-4 of the bacteria population survived initial (800 ns duration) shock pressures in water of 219 and 260 MPa. TEM images of shock recovered bacteria indicate cell wall indentations and rupture, possibly induced by inward invasion of medium into the cell wall. Notably cell wall rupture occurs dynamically at ˜0.1 times the static pressures E.coli have been demonstrated (Sharma et al., 2002) to survive and may be caused by Rayleigh-Taylor instabilities. We infer the invading fluid pressure may exceed the tensile strength of the cell wall. We assume the overpressures are limited to the initial shock pressure in water. Parameters for the Grady & Lipkin (1980) model of tensile failure versus time-scale (strain rate) are fit to present data, assuming that at low strain rates, overpressures exceeding cell Turgor pressure require ˜103 sec. This model, if validated by experiments at other timescales, may permit using short loading duration laboratory data to infer response of organisms to lower shock overpressures for the longer times (100 to 103 s) of planetary impacts. An Ahrens & O'Keefe (1987) shock attenuation model is then applied for Earth impactors. This model suggests that Earth impactors of radius 1.5 km induce shocks within water-filled cracks in rock to dynamic pressure such that stresses exceeding the survivability threshold of E. coli bacteria, to radii of 1.7-2.6×102 km. In contrast, a giant (1500 km radius) impactor produces a non survival zone for E. coli that encompasses the entire Earth.

    Here, we evaluated the potential activity of rapid Mycobacterium tuberculosis detection with loop-mediated isothermal amplification (LAMP), for the early diagnosis of tuberculous meningitis (TBM). Patients with suspected TBM from January 2014 to December 2015 were reviewed retrospectively. The cerebrospinalfluid(CSF) was collected. Acid-fast bacillus (AFB) staining, MGIT 960 culture, real-time fluorescent quantitative polymerase chain reaction (RTFQ PCR) and LAMP were performed. A total of 200 patients were included in the study. Of which, 172 of them were diagnosed with TBM (86.00%). The sensitivities of AFB staining, MGIT 960 culture, LAMP and RTFQ PCR for TBM diagnosis were 2.91% (5/172), 12.79% (22/172), 43.02% (74/172), and 34.30% (59/172), respectively. The sensitivity of LAMP for TBM was significantly higher than those of AFB staining and MGIT960 culture ( χ2 = 75.11, P < 0.001; χ2 = 43.88, P = 0.002). LAMP's sensitivity was however comparable to RTFQ PCR assay ( χ2 = 2.08, P = 0.130). The specificity, positive predictive value and negative predictive value of LAMP in the diagnosis of TBM were 92.86% (26/28), 97.37% (74/76) and 20.97 % (26/124), respectively. The overall consistency between LAMP and RTFQ PCR in the diagnosis of TBM was 88.5% (177/200), with Kappa value of 0.870. The consistency between LAMP and MGIT960 culture was 71% (142/200), with Kappa value of 0.730. Among all the methods, LAMP had high sensitivity, specificity and positive predictive value, showing high consistency with MGIT960 culture and RTFQ PCR.

    Developmental biologists have become increasingly aware that the wealth of knowledge generated through genetic studies of pre-implantation mouse development might not easily be translated to the human embryo. Comparative studies have been fueled by recent technological advances in single-cell analysis, allowing in-depth analysis of the human embryo. This field could shortly gain more momentum as novel genome editing technologies might, for the first time, also allow functional genetic studies in the human embryo. In this Spotlight article, we summarize the CRISPR-Cas9 genome editing system and discuss its potential applications and limitations in human pre-implantation embryos, and the ethical considerations thereof. © 2017.

    Analysis of human breath is a nonintrusive method to monitor both endogenous and exogenous chemicals found in the body. Several technologies were investigated and developed which are applicable to monitoring some organic molecules important in both physiological and pathological states. Two methods were developed for enriching the organic molecules exhaled in the breath of humans. One device is based on a respiratory face mask fitted with a polyethylene foam wafer; while the other device is a cryogenic trap utilizing an organic solvent. Using laboratory workers as controls, two organic molecules which occurred in the enriched breath of all subjects were tentatively identified as lactic acid and contisol. Both of these substances occurred in breath in sufficient amounts that the conventional method of gas-liquid chromatography was adequate for detection and quantification. To detect and quantitate trace amounts of chemicals in breath, another type of technology was developed in which analysis was conducted using high pressure liquid chromatography and mass spectrometry.

    Many families rely on child care outside the home, making these settings important influences on child development. Nearly 1.5 million children in the U.S. spend time in family child care homes (FCCHs), where providers care for children in their own residences. There is some evidence that children in FCCHs are heavier than those cared for in centers. However, few interventions have targeted FCCHs for obesity prevention. This paper will describe the application of the Intervention Mapping (IM) framework to the development of a childhood obesity prevention intervention for FCCHs Following the IM protocol, six steps were completed in the planning and development of an intervention targeting FCCHs: needs assessment, formulation of change objectives matrices, selection of theory-based methods and strategies, creation of intervention components and materials, adoption and implementation planning, and evaluation planning Application of the IM process resulted in the creation of the Keys to Healthy Family Child Care Homes program (Keys), which includes three modules: Healthy You, Healthy Home, and Healthy Business. Delivery of each module includes a workshop, educational binder and tool-kit resources, and four coaching contacts. Social Cognitive Theory and Self-Determination Theory helped guide development of change objective matrices, selection of behavior change strategies, and identification of outcome measures. The Keys program is currently being evaluated through a cluster-randomized controlled trial The IM process, while time-consuming, enabled rigorous and systematic development of intervention components that are directly tied to behavior change theory and may increase the potential for behavior change within the FCCHs.

    For decades, researchers have been developing a range of promising strategies in bone tissue engineering with the aim of producing a significant clinical benefit over existing therapies. However, a major problem concerns the traditional use of xenogeneic substances for the expansion of cells, which complicates direct clinical transfer. The study's aim was to establish a totally autologous sheep model as a basis for further preclinical studies and future clinical application. Ovine mesenchymal stromal cells (MSC) were cultivated in different concentrations (0%, 2%, 5%, 10%, and 25%) of either autologous serum (AS) or fetal calf serum (FCS). With an increase of serum concentration, enhanced metabolic activity and proliferation could be observed. There were minor differences between MSC cultivated in AS or FCS, comparing gene and protein expression of osteogenic and stem cell markers, morphology, and osteogenic differentiation. MSC implanted subcutaneously in the sheep model, together with a nanostructured bone substitute, either in stable block or moldable putty form, induced similar vascularization and remodeling of the bone substitute irrespective of cultivation of MSC in AS or FCS and osteogenic differentiation. The bone substitute in block form together with MSC proved particularly advantageous in the induction of ectopic bone formation compared to the cell-free control and putty form. It could be demonstrated that AS is suitable for replacement of FCS for cultivation of ovine MSC for bone tissue engineering purposes. Substantial progress has been made in the development of a strictly xenogeneic-free preclinical animal model to bring future clinical application of bone tissue engineering strategies within reach.

    To investigate the approaches of experienced speech-language pathologists (SLPs) to ethical reasoning and the processes they use to resolve ethical dilemmas. Ten experienced SLPs participated in in-depth interviews. A narrative approach was used to guide participants' descriptions of how they resolved ethical dilemmas. Individual narrative transcriptions were analyzed by using the participant's words to develop an ethical story that described and interpreted their responses to dilemmas. Key concepts from individual stories were then coded into group themes to reflect participants' reasoning processes. Five major themes reflected participants' approaches to ethical reasoning: (a) focusing on the well-being of the client, (b) fulfilling professional roles and responsibilities, (c) attending to professional relationships, (d) managing resources, and (e) integrating personal and professional values. SLPs demonstrated a range of ethical reasoning processes: applying bioethical principles, casuistry, and narrative reasoning when managing ethical dilemmas in the workplace. The results indicate that experienced SLPs adopted an integrated approach to ethical reasoning. They supported clients' rights to make health care choices. Bioethical principles, casuistry, and narrative reasoning provided useful frameworks for facilitating health professionals' application of codes of ethics to complex professional practice issues.

    Flying an aircraft requires a considerable degree of coordination, particularly during aerobatic activities such as rolls, loops and turns. Only one previous study has examined the magnitude of muscle activity required to fly an aircraft, and that was restricted to takeoff and landing maneuvers. The aim of this study was to examine the phasing of muscle activation and control forces of novice and experienced pilots during more complex simulated flight maneuvers. There were 12 experienced and 9 novice pilots who were tested on an Aermacchi flight simulator while performing a randomized set of rolling, looping, and turning maneuvers. Four different runaway trim settings were used to increase the difficulty of the turns (elevator-up, elevator-down, aileron-left, and aileron-right). Variables recorded included aircraft attitude, pilot applied forces, and electromyographic (EMG) activity. Discriminant function analysis was used to distinguish between novice and experienced pilots. Over all maneuvers, 70% of pilots were correctly classified as novice or experienced. Better levels of classification were achieved when maneuvers were analyzed individually (67-91%), although the maneuvers that required the greatest force application, elevator-up turns, were unable to discriminate between novice and experienced pilots. There were no differences in the phasing of muscle activity between experienced and novice pilots. The only consistent difference in EMG activity between novice and experienced pilots was the reduced EMG activity in the wrist extensors of experienced pilots (p < 0.05). The increased wrist extensor activity of the novice pilots is indicative of a distal control strategy, whereby distal muscles with smaller motor units are used to perform a task that requires precise control. Muscle activity sensors could be used to detect the onset of high G maneuvers prior to any change in aircraft attitude and control G-suit inflation accordingly.

    Objective: To analyze the changes and relationship of early hemodynamic indexes of patients with large area burns monitored by pulse contour cardiac output (PiCCO) monitoring technology, so as to assess the guiding value of this technology in the treatment of patients with large area burns during shock period. Methods: Eighteen patients with large area burns, confirming to the study criteria, were admitted to our unit from May 2016 to May 2017. Pulse contour cardiac output index (PCCI), systemic vascular resistance index (SVRI), global end-diastolic volume index (GEDVI), and extravascular lung water index (EVLWI) of patients were monitored by PiCCO instrument from admission to post injury day (PID) 7, and they were calibrated and recorded once every four hours. The fluid infusion coefficients of patients at the first and second 24 hours post injury were calculated. The blood lactic acid values of patients from PID 1 to 7 were also recorded. The correlations among PCCI, SVRI, and GEDVI as well as the correlation between SVRI and blood lactic acid of these 18 patients were analyzed. Prognosis of patients were recorded. Data were processed with one-way analysis of variance, single sample t test and Bonferroni correction, Pearson correlation analysis, and Spearman rank correlation analysis. Results: (1) There was statistically significant difference in PCCI value of patients from post injury hour (PIH) 4 to 168 ( F =7.428, P <0.01). The PCCI values of patients at PIH 4, 8, 12, 16, 20, and 24 were (2.4±0.9), (2.6±1.2), (2.2±0.6), (2.6±0.7), (2.8±0.6), and (2.7±0.7) L·min(-1)·m(-2,) respectively, and they were significantly lower than the normal value 4 L·min(-1)·m(-2)( t =-3.143, -3.251, -11.511, -8.889, -6.735, -6.976, P <0.05 or P <0.01). At PIH 76, 80, 84, 88, 92, and 96, the PCCI values of patients were (4.9±1.5), (5.7±2.0), (5.9±1.7), (5.5±1.3), (5.3±1.1), and (4.9±1.4) L·min(-1)·m(-2,) respectively, and they were significantly higher than the

    The U.S. Geological Survey (USGS) supports the use of Earth observation data for food security monitoring through its role as an implementing partner of the Famine Early Warning Systems Network (FEWS NET). The USGS Earth Resources Observation and Science (EROS) Center has developed tools designed to aid food security analysts in developing assumptions of agro-climatological outcomes. There are four primary steps to developing agro-climatology assumptions; including: 1) understanding the climatology, 2) evaluating current climate modes, 3) interpretation of forecast information, and 4) incorporation of monitoring data. Analysts routinely forecast outcomes well in advance of the growing season, which relies on knowledge of climatology. A few months prior to the growing season, analysts can assess large-scale climate modes that might influence seasonal outcomes. Within two months of the growing season, analysts can evaluate seasonal forecast information as indicators. Once the growing season begins, monitoring data, based on remote sensing and field information, can characterize the start of season and remain integral monitoring tools throughout the duration of the season. Each subsequent step in the process can lead to modifications of the original climatology assumption. To support such analyses, we have created an agro-climatology analysis tool that characterizes each step in the assumption building process. Satellite-based rainfall and normalized difference vegetation index (NDVI)-based products support both the climatology and monitoring steps, sea-surface temperature data and knowledge of the global climate system inform the climate modes, and precipitation forecasts at multiple scales support the interpretation of forecast information. Organizing these data for a user-specified area provides a valuable tool for food security analysts to better formulate agro-climatology assumptions that feed into food security assessments. We have also developed a knowledge

    Bangladesh is the lowest riparian of the huge system of the Ganges, Brahmaputra and Meghna (GBM) basins, second to that of Amazan, with 1.75 million sq-km catchment area, only 7% is inside Bangladesh. High inflow from GBM associated with the intense rainfall is the source of flood in Bangladesh. Flood Forecasting and Early Warning (FFEW) is the mandate and responsibility of Bangladesh Water Development Board (BWDB) and Flood Forecasting and Warning Center (FFWC) under BWDB has been carrying out this responsibility since 1972 and operational on 7-days a week during monsoon (May to October). FFEW system started with few hours lead time has been upgraded up to to 5-days with reasonable accuracy. At FFWC numerical Hydrodynamic model is used for generating water level (WL) forecast upto 5-days at 54 points on 29 rivers based on real-time observed WL of 83 and rainfall of 56 stations with boundary estimationa on daily basis. Main challenge of this system is the boundary estimation is the limited upstream data of the transboundary rivers, obstacle for increasing lead-time for FFEW. The satellite based upper catchment data may overcome this limitation. Recent NASA-French joint Satellite mission JASON-2 records Water Elevation (WE) and it may be used within 24 hours. Using JASON-2 recorded WE data of 4 and 3 virtual stations on the Ganges and Brahmaputra rivers , respectively (upper catchment), a new methodology has been developed for increasing lead time of forecast. Correlation between the JASON-2 recorded WE on the virtual stations at the upper catchment and WL of 2 dominating boundary stations at model boundary on the Ganges and Brahmaputra has been derived for generating WL forecast at those 2 boundary stations, which used as input in model. FFWC has started experimental 8-days lead-time WL forecast at 09 stations (5 in Brahmaputra and 4 in Ganges) using generated boundary data and regularly updating the results in the website.

    Background Most incorrect diagnoses involve at least one cognitive error, of which premature closure is the most prevalent. While metacognitive strategies can mitigate premature closure in inexperienced learners, these are rarely studied in experienced physicians. Our objective here was to evaluate the effect of analytic information processing on diagnostic performance of nephrologists and nephrology residents. Methods We asked nine nephrologists and six nephrology residents at the University of Calgary and Glasgow University to diagnose ten nephrology cases. We provided presenting features along with contextual information, after which we asked for an initial diagnosis. We then primed participants to use either hypothetico-deductive reasoning or scheme-inductive reasoning to analyze the remaining case data and generate a final diagnosis. Results After analyzing initial hypotheses, both nephrologists and residents improved the accuracy of final diagnoses (31.1% vs. 65.6%, p < 0.001, and 40.0% vs. 70.0%, p < 0.001, respectively). We found a significant interaction between experience and analytic processing strategy (p = 0.02): nephrology residents had significantly increased odds of diagnostic success when using scheme-inductive reasoning (odds ratio [95% confidence interval] 5.69 [1.59, 20.33], p = 0.07), whereas the performance of experienced nephrologists did not differ between strategies (odds ratio 0.57 [0.23, 1.39], p = 0.20). Discussion Experienced nephrologists and nephrology residents can improve their performance by analyzing initial diagnostic hypotheses. The explanation of the interaction between experience and the effect of different reasoning strategies is unclear, but may relate to preferences in reasoning strategy, or the changes in knowledge structure with experience.

    The aim of this study was to determine the effect of caffeine intake on overall basketball performance in experienced players. A double-blind, placebo-controlled, randomized experimental design was used for this investigation. In two different sessions separated by one week, 20 experienced basketball players ingested 3 mg of caffeine/kg of body mass or a placebo. After 60 min, participants performed 10 repetitions of the following sequence: Abalakov jump, Change-of-Direction and Acceleration Test (CODAT) and two free throws. Later, heart rate, body impacts and game statistics were recorded during a 20-min simulated basketball game. In comparison to the placebo, the ingestion of caffeine increased mean jump height (37.3 ± 6.8 vs. 38.2 ± 7.4 cm; p = 0.012), but did not change mean time in the CODAT test or accuracy in free throws. During the simulated game, caffeine increased the number of body impacts (396 ± 43 vs. 410 ± 41 impacts/min; p < 0.001) without modifying mean or peak heart rate. Caffeine also increased the performance index rating (7.2 ± 8.6 vs. 10.6 ± 7.1; p = 0.037) during the game. Nevertheless, players showed a higher prevalence of insomnia (19.0 vs. 54.4%; p = 0.041) after the game. Three mg of caffeine per kg of body mass could be an effective ergogenic substance to increase physical performance and overall success in experienced basketball players. PMID:28925969

    Experienced meditators typically report that they experience time slowing down in meditation practice as well as in everyday life. Conceptually this phenomenon may be understood through functional states of mindfulness, i.e., by attention regulation, body awareness, emotion regulation, and enhanced memory. However, hardly any systematic empirical work exists regarding the experience of time in meditators. In the current cross-sectional study, we investigated whether 42 experienced mindfulness meditation practitioners (with on average 10 years of experience) showed differences in the experience of time as compared to 42 controls without any meditation experience matched for age, sex, and education. The perception of time was assessed with a battery of psychophysical tasks assessing the accuracy of prospective time judgments in duration discrimination, duration reproduction, and time estimation in the milliseconds to minutes range as well with several psychometric instruments related to subjective time such as the Zimbardo Time Perspective Inventory, the Barratt Impulsivity Scale and the Freiburg Mindfulness Inventory. In addition, subjective time judgments on the current passage of time and retrospective time ranges were assessed. While subjective judgements of time were found to be significantly different between the two groups on several scales, no differences in duration estimates in the psychophysical tasks were detected. Regarding subjective time, mindfulness meditators experienced less time pressure, more time dilation, and a general slower passage of time. Moreover, they felt that the last week and the last month passed more slowly. Overall, although no intergroup differences in psychophysical tasks were detected, the reported findings demonstrate a close association between mindfulness meditation and the subjective feeling of the passage of time captured by psychometric instruments.

    Physicians often deal with emotions arising from both patients and themselves; however, management of intense emotions when they arise in the presence of patients is overlooked in research. The aim of this study is to inspect physicians' intense emotions in this context, how these emotions are displayed, coping strategies used, adjustment behaviors, and the impact of the emotional reactions on the physician-patient relationship. A total of 127 physicians completed a self-report survey, built from a literature review. Participants were recruited in 3 different ways: through a snowball sampling procedure, via institutional e-mails, and in person during service meetings. Fifty-two physicians (43.0%) reported experiencing intense emotions frequently. Although most physicians (88.6%) tried to control their reactions, several reported not controlling themselves. Coping strategies to deal with the emotion at the moment included behavioral and cognitive approaches. Only the type of reaction (but not the emotion's valence, duration, relative control, or coping strategies used) seemed to affect the physician-patient relationship. Choking-up/crying, touching, smiling, and providing support were significantly associated with an immediate positive impact. Withdrawing from the situation, imposing, and defending oneself were associated with a negative impact. Some reactions also had an extended impact into future interactions. Experiencing intense emotions in the presence of patients was frequent among physicians, and the type of reaction affected the clinical relationship. Because many physicians reported experiencing long-lasting emotions, these may have important clinical implications for patients visiting physicians while these emotions last. Further studies are needed to clarify these results.

    The fatigue that is observed in patients who are undergoing dialysis is usually associated with an impaired quality of life. The present cross-sectional study was conducted from January to April 2009 in three hemodialysis units in Kuala Lumpur, Malaysia. In this study, the Multidimensional Fatigue Inventory and Depression Anxiety and Stress Score 21 were used to determine the level of fatigue, depression, anxiety, and stress of patients who were undergoing dialysis. The data were obtained from a calculated sample of 116 and a total of 103 respondents participated in the study. A total of 56 (54.4%) and 47 (45.6%) respondents experienced a high level and a low level of fatigue, respectively. There was a significant relationship between the duration of treatment and the level of fatigue. The respondents who had been receiving treatment for > 2 years experienced more fatigue, compared to the respondents who had been undergoing hemodialysis for > 2 years. There was a significant difference in relation to the age of the participants regarding the level of fatigue. No significant relationship between the sex of the participants, anemia, depression, anxiety, stress, and the level of fatigue was observed. Special attention needs to be paid to both the younger and older adults who are receiving treatment. In addition, proper planning is needed for the patients regarding their daily activities in order to reduce fatigue. Nurses who work in hemodialysis units are recommended to provide exercise classes or group therapy in order to boost the energy levels among patients who are undergoing dialysis. Health professionals should provide appropriate treatment for patients who are experiencing fatigue in order to prevent any other complications that could arise. © 2011 Blackwell Publishing Asia Pty Ltd.

Although most physicians (88.6%) tried to control their reactions, several reported not controlling themselves. Coping strategies to deal with the emotion at the moment included behavioral and cognitive approaches. Only the type of reaction (but not the emotion’s valence, duration, relative control, or coping strategies used) seemed to affect the physician-patient relationship. Choking-up/crying, touching, smiling, and providing support were significantly associated with an immediate positive impact. Withdrawing from the situation, imposing, and defending oneself were associated with a negative impact. Some reactions also had an extended impact into future interactions. Conclusion: Experiencing intense emotions in the presence of patients was frequent among physicians, and the type of reaction affected the clinical relationship. Because many physicians reported experiencing long-lasting emotions, these may have important clinical implications for patients visiting physicians while these emotions last. Further studies are needed to clarify these results. PMID:27479947

    In addition to technical expertise, surgical competence requires effective non-technical skills to ensure patient safety and maintenance of standards. Recently the Royal Australasian College of Surgeons implemented a new Surgical Education and Training (SET) curriculum that incorporated non-technical skills considered essential for a competent surgeon. This study sought to compare the non-technical skills of experienced surgeons who completed their training before the introduction of SET with the non-technical skills of more recent trainees. Surgical trainees and experienced surgeons undertook a simulated scenario designed to challenge their non-technical skills. Scenarios were video recorded and participants were assessed using the Non-Technical Skills for Surgeons (NOTSS) scoring system. Participants were divided into subgroups according to years of experience and their NOTSS scores were compared. For most NOTSS elements, mean scores increased initially, peaking around the time of Fellowship, before decreasing roughly linearly over time. There was a significant downward trend in score with increasing years since being awarded Fellowship for six of the 12 NOTSS elements: considering options (score -0·015 units per year), implementing and reviewing decisions (-0·020 per year), establishing a shared understanding (-0·014 per year), setting and maintaining standards (-0·024 per year), supporting others (-0·031 per year) and coping with pressure (-0·015 per year). The drop in NOTSS score was unexpected and highlights that even experienced surgeons are not immune to deficiencies in non-technical skills. Consideration should be given to continuing professional development programmes focusing on non-technical skills, regardless of the level of professional experience. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

    A vibration instability phenomenon experienced in operating high pressure syn gas centrifugal compressors in two ammonia plants is described. The compressors were monitored by orbit and spectrum analysis for changes from baseline readings. It is found that internal hysteresis was the major destabilizing force; however, the problem was further complicated by seal lockup at the suction end of the compressor. A coupling lockup problem and a coupling fit problem, which frettage of the shaft, are also considered as contributors to the self excited vibrations.

    "Freshman's week" (FW) is a Norwegian initiation ritual to higher education. Previous research has suggested that FW-participation is associated with better social adjustment to the student setting, as well as heavy alcohol use both during and after the event. In this study, we aimed to identify characteristics associated with participation in FW and characteristics associated with experiencing adverse effects of alcohol use during FW. Students in the city of Bergen, Norway participated in a survey during fall 2015, shortly after FW. The current sample consisted of the first-year students (N = 4, 401, estimated response rate: 49%). The sample's mean age was 24 years (range: 17-73 years), 65% were females, and the majority were born in Norway (93%). Logistic regressions were conducted to identify characteristics associated with participation in FW and experiencing adverse effects. A total of 64% of the first-year students reported participation in FW, and 27% of these reported experiencing at least one adverse alcohol-related effect during FW. Participation in FW was positively associated with being single (OR = 1.29), extroversion (OR = 1.18), and alcohol use (OR = 1.28), and inversely associated with age (OR = 0.70), and having children (OR = 0.36). Several characteristics (e.g., alcohol use (OR = 1.84), extroversion (OR = 0.60), symptoms of depression (OR = 1.60)) were associated with an increased risk of experiencing adverse effects of alcohol use during participation. The current results suggest that initiatives for increasing the participation rate in FW, reducing alcohol use during FW, and decreasing the occurrence of adverse alcohol effects during FW are warranted. Aiming to reduce the focus on alcohol use during FW, and seeking to make FW more available and enjoyable for students with other priorities, students who do not match the stereotype of the typical first-year student, and less sociable students, might both

In a prospective study during a period of 6 months, a total of 178 patients in term (37-41 weeks) consulting our obstetric unit for uterine contraction, were enrolled. Patients were examined separately by a midwife and a resident and separated into "true labor group" and "false labor group". The clinical characteristics of true versus false labor patients were compared. ROC curves were developed to determine an optimal cervical length and uterocervical angle for prediction of true labor. The prevalence of real labor was 57.3%. Patients who were in true labor had more painful and more frequent contractions. The "true labor" group had shorter cervical length and larger uterocervical angle. The optimal CL cut-off was 1.4mm with a specificity of 73% (RR 4.3, sensibility 63%, PPV 14%, NPV 95%). The optimal UCA cut off was 123° (RR 6.7, sensitivity 50%, specificity of 83%, PPV 10%, NPV 96%). The best performance was demonstrated by combined testing, yielding LHR+ that rich 13. In this study, we reported a new application of ultrasound to identify false labor and avoid unnecessary hospitalization with obstetric and adverse economic impacts.

  10. Isomer profiling of perfluorinated substances as a tool for source tracking: a review of early findings and future applications.

    The two major manufacturing techniques for perfluorochemicals can be distinguished based on the isomeric profile of their products. ECF (major use from 1950s to 2002) results in a product containing both linear and branched isomers, while telomerization (major use from 2002 to present) typically yields an isomerically pure, linear product. Among the most important question today, which has implication for future regulation of these chemicals, is to what extent human and environmental exposure is from historical products (i.e., ECF) versus currently manufactured fluorochemicals (i.e., telomer). Perfluoroalkyl-chain branching can also affect the physical and chemical properties of these chemicals, which may influence their environmental transport and degradation, partitioning, bioaccumulation, pharmacokinetics, and toxicity. Unless perfluorinated substances are considered as individual isomers, much of this information will be overlooked or missed altogether, which could potentially lead to inaccuracies in human and environmental risk assessments. In this review, we have highlighted novel findings, current knowledge gaps, and areas for improvement based on early experiments on the disposition of PFA and PFA-precursor isomers in the environment. We have also emphasized the wealth of information that can potentially be gleaned from future work in this area, which renders routine adoption of isomer-specific methodologies an attractive and logical next step in the progression of fluorochemicals analysis. However, despite vast improvements in recent years, a fast and comprehensive method capable of separating all major PFA and PFA-precursor isomers, while removing interferences is still required before these methods becomes routine in most labs. Purified and characterized standards of PFOA and PFOS that have isomer profiles consistent with those of historically produced (i.e., 3M) PFOS and PFOA are also required. The limited data available on PFA isomer profiles that

In this context, an assessment of the factors controlling the geotechnical and hydrological features is crucial in order to understand the occurrence of slope instability mechanisms and to provide reliable forecasting of the hydrogeological hazard occurrence, especially in relation to weather events. In particular, the model and the soil characterization were applied in back analysis, in order to assess the reliability of the model through validation of the results with landslide events that occurred during the period. The validation was performed on four past events of intense rainfall that have affected Valle d'Aosta region between 2008 and 2010 years triggering fast shallows landslides. The simulations show substantial improvement of the reliability of the results compared to the use of literature parameters. A statistical analysis of the HIRESSS outputs in terms of failure probability has been carried out in order to define reliable alert levels for regional landslide early warning systems.

    Earthquake parameter estimations using nearest neighbor searching among a large database of observations can lead to reliable prediction results. However, in the real-time application of Earthquake Early Warning (EEW) systems, the accurate prediction using a large database is penalized by a significant delay in the processing time. We propose to use a multidimensional binary search tree (KD tree) data structure to organize large seismic databases to reduce the processing time in nearest neighbor search for predictions. We evaluated the performance of KD tree on the Gutenberg Algorithm, a database-searching algorithm for EEW. We constructed an offline test to predict peak ground motions using a database with feature sets of waveform filter-bank characteristics, and compare the results with the observed seismic parameters. We concluded that large database provides more accurate predictions of the ground motion information, such as peak ground acceleration, velocity, and displacement (PGA, PGV, PGD), than source parameters, such as hypocenter distance. Application of the KD tree search to organize the database reduced the average searching process by 85% time cost of the exhaustive method, allowing the method to be feasible for real-time implementation. The algorithm is straightforward and the results will reduce the overall time of warning delivery for EEW.

    The AQ research community has a long legacy of using space-based observations (e.g., Solar Backscatter Ultraviolet Instrument [SBUV], Global Ozone Monitoring Experiment [GOME], Ozone Monitoring Instrument [OMI], and the Ozone Mapping & Profiler Suite [OMPS]) to study atmospheric chemistry. These measurements have been used to observe day-to-day and year-to-year changes in atmospheric constituents. However, they have not been able to capture the diurnal variability of pollution with enough temporal or spatial fidelity and a low enough latency for regular use by operational decision makers. As a result, the operational AQ community has traditionally relied on ground-based (e.g., collection stations, LIDAR) and airborne observing systems to study tropospheric chemistry. In order to maximize its utility for applications and decision support, there is a need to educate the community about the game-changing potential for the geostationary TEMPO mission well ahead of its expected launch date early in the third decade of this millinium. This NASA mission will engage user communities and enable science across the NASA Applied Science Focus Areas of Health and Air Quality, Disasters, Water Resources, and Ecological Forecasting, In addition, topics discussed will provide opportunities for collaborations extending TEMPO applications to future program areas in Agriculture, Weather and Climate (including Numerical Weather Prediction), Energy, and Oceans.

    Despite evidence that psychological distress manifests itself in underreported and atypical ways, few studies have assessed these symptoms in women who have experienced intrauterine insemination (IUI). The aim of this study was to examine the prevalence of psychological distress and explore the relationships among psychological distress, various demographic characteristics, and somatic symptoms in women who had received IUI treatment in Taiwan. A cross-sectional study design was used in this study. The 117 participants were recruited from a teaching hospital in northern Taiwan. The brief symptom rating scale (BSRS-5) was used as the measurement instrument, and scores of more than 5 on the BSRS-5 were used to mark the boundary between milder and more severe psychological distress. Demographic characteristics and somatic symptoms of IUI that contributed most significantly to psychological distress were identified from the data. Thirty-eight (32.5%) participants experienced psychological distress. Psychological distress was most common in participants (a) with husbands who were an only son, (b) who had taken medication during the previous week, (c) with an education level below college or university, and (d) who reported feeling faint. The factors studied are important to understand psychological distress in women who have undergone IUI treatment.

    Racial discrimination is an established life course social determinant of health associated with adverse psychological outcomes among minority populations. However, little is known about the extent to which Aboriginal people in Canada may experience racial discrimination and consequent adverse psychological effects. This study sought to measure the extent to which Aboriginal university students living in an urban area of Canada experienced racism, to triangulate this evidence with US data and qualitative findings, and to examine the impact of these experiences on mental health. Data for this mixed method study were collected via in-person surveys with a volunteer sample of Aboriginal university students (n = 60) living in a mid-sized city in central Canada in 2008-2009. Results indicate Aboriginal university students experienced more frequent racism across a greater number of life situations than African- and Latino-American adults in the United States. Student reactions to these experiences were symptomatic of what has been termed racial battle fatigue in the United States. Students who considered themselves traditional or cultural Aboriginal persons were significantly more likely to experience discrimination. Results underline the need for policies aimed at reducing racism directed at Aboriginal people in urban areas and the growth of services to help Aboriginal people cope with these experiences. Results highlight the need for further research to determine the potential pathogenic consequences of racial discrimination for Aboriginal people in Canada.

    Microaggressions are subtle verbal or behavioral communications of disparaging messages to people based upon membership in a socially marginalized group. Their negative impact has been demonstrated for racial/ethnic groups, gender, sexual orientation, and physical disability, but currently no research exists on microaggressions as experienced by persons with mental illnesses. Qualitative data were gathered from 4 focus groups with 2 samples: adult mental health consumers in an assertive community treatment program and college students with mental illness diagnoses. Focus group transcripts were then analyzed using an open coding approach (Strauss & Corbin, 1990) to identify hierarchical themes and categories. Five major themes were identified, including invalidation, assumption of inferiority, fear of mental illness, shaming of mental illness, and second class citizen. Perpetrators of microaggressions were most commonly identified as being close friends, family members, and authority figures. Importantly, participants reported experiencing more overt discrimination experiences than subtle microaggression experiences. Reported negative outcomes related to microaggression experiences included isolation, negative emotions, and treatment nonadherence. Reported consequences of microaggressions have important implications for mental health treatment, especially as perpetrators were reported to include treatment providers and were usually unaware of such negative social exchanges. Loss of social support reported by participants and the frequent occurrence of microaggressions within close relationships implies these experiences could contribute to internalization of stigmatizing attitudes toward mental illness. Directions for future research include an investigation of motivation and reasoning behind perpetration of microaggressions against persons with mental illnesses. (c) 2015 APA, all rights reserved).

    2006-09-01

    Caring has been identified as a desirable indicator of professional behavior in the physical therapy profession and as a necessary value for good patient care. Yet caring is an elusive concept with multiple meanings. The present aim was to describe the nature of caring in the clinical practice of five experienced physical therapists. Purposive sampling was used to recruit five experienced physical therapists. Each physical therapist underwent a series of in-depth, open-ended interviews that were transcribed and coded for themes based on similarities and differences. The analysis resulted in three themes: ethics of caring, risks and conflicts of caring, and learning to care. The data indicated for four of the five participants that caring constituted an ethics of practice or moral orientation. Their moral orientation influenced moral judgment that was integrated throughout their clinical and ethical decision-making practice. The findings stress the difficulty of caring in a managed care health care environment that results in conflicting demands for physical therapists to care for their patients in a system that increasingly values cost control and profit margin. However, the findings also describe the ultimate rewards associated with the practice of an ethics of caring in physical therapy practice.

    This article presents the results of a study currently underway looking at the transmission of vocational skills between health care workers in a French hospital. The aim was to show that health care workers, in addition to their work with patients, also have to incorporate the transmission of vocational skills into their daily activities. Thirteen transmission situations were observed and analyzed by means of an activity-focused ergonomic work analysis, with the aim of reporting on this "invisible work". The population studied was composed of nurses and the nursing assistants from three different units in one hospital. The results show that the work required to integrate and supervise new staff members is left to the discretion of health care workers. This means they are constantly required to arbitrate on both an individual and collective basis between providing health care for patients and supporting new members of staff. The content of the transmission goes beyond the prescribed tasks and technical knowledge, as staff members also pass on their professional strategies (individual and collective), rules of practice and ethical considerations. Supervising students also offers experienced workers the opportunity to share their professional practices. This study highlights the issues arising from this transmission activity for the experienced workers, new workers, patients and the hospital.

    The present study aimed to (a) demonstrate the effect of positive-negative framing on experienced criminal justice decision makers, (b) examine the debiasing effect of visually structured risk messages, and (c) investigate whether risk perceptions mediate the debiasing effect of visual aids on decision making. In two phases, 60 senior police officers estimated the accuracy of a counterterrorism technique in identifying whether a known terror suspect poses an imminent danger and decided whether they would recommend the technique to policy makers. Officers also rated their confidence in this recommendation. When information about the effectiveness of the counterterrorism technique was presented in a numerical format, officers' perceptions of accuracy and recommendation decisions were susceptible to the framing effect: The technique was perceived to be more accurate and was more likely to be recommended when its effectiveness was presented in a positive than in a negative frame. However, when the information was represented visually using icon arrays, there were no such framing effects. Finally, perceptions of accuracy mediated the debiasing effect of visual aids on recommendation decisions. We offer potential explanations for the debiasing effect of visual aids and implications for communicating risk to experienced, professional decision makers.

    In this study, an ambiguous loss framework as described by Boss (1999, Ambiguous loss: Learning to live with unresolved grief, First Harvard University Press, Cambridge, MA) was used to examine and understand the family experiences of Mexican immigrant agricultural workers in Minnesota. Transcripts from interviews with 17 workers in Minnesota and 17 family members in Mexico were analyzed using qualitative methodology to identify experiences of ambiguous loss in the participants' narratives. Key dimensions of ambiguous loss identified in the transcripts include: psychological family, feelings of chronic/recurring loss, finding support, and meaning making. In the category of psychological family, participants in both Mexico and the United States mourned the physical absence of their family members and experienced ambiguity regarding family responsibilities, but worked to maintain their psychological roles within the family. In the category of chronic/recurring loss, participants in both countries experienced chronic worry from not knowing if family members were safe, ambiguity regarding when the immigrant would return, and chronic stressors that compounded these feelings of loss. Participants in both countries coped with both real and ambiguous losses by accessing family support and by using ambiguous communication to minimize worry. Participants in Mexico also accessed work and community-based support. Participants in both countries made meaning of the ambiguous loss by identifying ways their lives were improved and goals were met as a result of the immigration for agricultural work in Minnesota. © 2015 Family Process Institute.

    Sexual violence research in China is in its early stages. This study described the sexual violence experience of college students in Guangzhou, China, and examined the individual and family factors associated with increased sexual perpetration and victimisation. A cross-sectional survey of 2200 college students from three universities in Guangzhou, China, was conducted in 2010. Data on sexual perpetration and/or victimisation experienced during the past 12 months were collected. Multinomial logistic regression was used to assess the individual and family factors associated with odds of sexual assault perpetration, victimisation, or both. Over a quarter (25.4%) of students experienced at least one form of sexual violence during the past 12 months, either as a perpetrator or as a victim, and nearly 10% of students experienced both perpetration and victimisation. The number of students who identified themselves as being solely a victim was almost three times lower than being a perpetrator only (n=87 vs n=246). Engaging in risky behaviours was associated with increased odds of being a perpetrator and being both a perpetrator and a victim. Prior mistreatment by teachers or bullying by others was linked to increased risk of both perpetration and victimisation. Male students who had indulgent parents (responsive but not demanding) were at increased risk of perpetration compared with those students with authoritative parents (responsive and demanding). The findings add to empirical data on sexual violence in college students and reinforce the urgent need for implementation of successful sexual violence prevention programmes in China.

    2016-07-26

    As part of an electronic dashboard operated by Public Health Wales, senior managers at hospitals in Wales report daily "escalation" scores which reflect management opinion on the pressure a hospital is experiencing and ability to meet ongoing demand with respect to unscheduled care. An analysis was undertaken of escalation scores returned for 18 hospitals in Wales between the years 2006 and 2014 inclusive, with a view to identifying systematic temporal patterns in pressure experienced by hospitals in relation to unscheduled care. Exploratory data analysis indicated the presence of within-year cyclicity in average daily scores over all hospitals. In order to quantify this cyclicity, a Generalised Linear Mixed Model was fitted which incorporated a trigonometric function (sine and cosine) to capture within-year change in escalation. In addition, a 7-level categorical day of the week effect was fitted as well as a 3-level categorical Christmas holiday variable based on patterns observed in exploration of the raw data. All of the main effects investigated were found to be statistically significant. Firstly, significant differences emerged in terms of overall pressure reported by individual hospitals. Furthermore, escalation scores were found to vary systematically within-year in a wave-like fashion for all hospitals (but not between hospitals) with the period of highest pressure consistently observed to occur in winter and lowest pressure in summer. In addition to this annual variation, pressure reported by hospitals was also found to be influenced by day of the week (low at weekends, high early in the working week) and especially low over the Christmas period but high immediately afterwards. Whilst unpredictable to a degree, quantifiable pressure experienced by hospitals can be anticipated according to models incorporating systematic temporal patterns. In the context of finite resources for healthcare services, these findings could optimise staffing schedules and

    Introduction Not only do transgender female sex workers have some of the highest rates of sexually transmitted infections (STI), human immunodeficiency virus (HIV), and experienced stigma, they also have higher likelihood of early sexual debut and some of the lowest levels of educational attainment compared to other stigmatized populations. Some of the most common interventions designed to reduce transmission of HIV and STIs seek to educate high-risk groups on sexual health and encourage condom use across all partner types; however, reaching stigmatized populations, particularly those in resource-limited settings, is particularly challenging. Considering the importance of condom use in stopping the spread of HIV, the aim of this study was two-fold; first to characterize this hard-to-reach population of transgender female sex workers in the Dominican Republic, and second, to assess associations between their HIV knowledge, experienced stigma, and condom use across three partner types. Methods We analyzed self-reported data from the Questionnaire for Transgender Sex Workers (N = 78). Respondents were interviewed at their workplaces. Univariate and bivariate analyses were employed. Fisher Chi-square tests assessed differences in HIV knowledge and experienced stigma by condom use across partner types. Results HIV knowledge was alarmingly low, condom use varied across partner type, and the respondents in our sample had high levels of experienced stigma. Average age of first sexual experience was 13.12 years with a youngest age reported of 7. Dominican Republic statutory rape laws indicate 18 years is the age of consent; thus, many of these transgender women’s first sexual encounters would be considered forcible (rape) and constitute a prosecutable crime. On average, respondents reported 8.45 sexual partners in the prior month, with a maximum of 49 partners. Approximately two thirds of respondents used a condom the last time they had sex with a regular partner. This

    The aim of the present study was to examine the clinical merits of joint application of β-sodium aescinate and mannitol for the treatment of early swelling of upper limb trauma after surgery. We verified whether the expression of serum aquaporin 1 (AQP-1) was involved in swelling mechanism. A total of 102 patients with swelling after upper limb trauma surgery were enrolled into the study and divided randomly into 3 groups (n=34 cases per group). Group A was treated with β-sodium aescinate; group B was treated with with mannitol and group C was treated with both β-sodium aescinate and mannitol. The expression level of AQP-1, and clinical effects and complications before and after treatment were compared§. The time of swelling subsidence in group C was significantly shorter than that of the other two groups and differences were statistically significant (P<0.05). The recovery ratio and total efficiency in group C were significantly higher than those in other two groups and differences were statistically significant (P<0.05). Three and seven days after treatment, the AQP-1 levels in group A and group C were decreased and AQP-1 level decreased further with time. Differences of comparison within groups were statistically significant (P<0.05), although the differences of comparison between the groups showed no statistical significance (P>0.05). We also compared the AQP-1 level in group B before and after treatment, and the differences were not statistically significant (P>0.05). When the complication incidence in the 3 groups was compared, no statistical significance was detected (P>0.05). We concluded that the joint use of β-sodium aescinate and mannitol in treating early swelling after upper limb trauma surgery produced satisfactory outcomes. This might be related to reduction of the AQP-1 level.

    Objective: to identify experiences and feelings on the organ donation process, from the perspective of a relative of an organ donor in a transplant unit. Method: this was exploratory research using a qualitative approach, performed with seven family members of different organ donors, selected by a lottery. Sociodemographic data and the experiences regarding the donation process were collected through semi-structured interviews. The language material was transcribed and submitted to content analysis. Results: poor sensitivity of the medical staff communicating the relative's brain death - the potential donor - and the lack of socio-emotional support prior to the situation experienced by the family was highlighted by participants. Conclusions: the study identified the need to provide social-emotional support for families facing the experience of the organ donation process. From these findings, other care and management practices in health must be discussed to impact the strengthening of the family ties, post-donation, as well as the organ procurement indexes.

    2006-01-01

    Performance on automatic speech recognition (ASR) systems for users with physical disabilities varies widely between individuals. The goal of this study was to discover some key factors that account for that variation. Using data from 23 experienced ASR users with physical disabilities, the effect of 20 different independent variables on recognition accuracy and text entry rate with ASR was measured using bivariate and multivariate analyses. The results show that use of appropriate correction strategies had the strongest influence on user performance with ASR. The amount of time the user spent on his or her computer, the user's manual typing speed, and the speed with which the ASR system recognized speech were all positively associated with better performance. The amount or perceived adequacy of ASR training did not have a significant impact on performance for this user group.

    2007-09-01

    This study examined both the meanings and sources/causes of stress from the perspectives of lesbians and gay men (n=30), using a series of focus groups. The findings suggest that stress is considered a part of life itself, and is perceived to contain both negative (e.g. detrimental effects on health and overall functioning, unfairness, out-of-control), and positive (e.g. a motivator, growth-facilitator) elements. The sources/causes of stress (i.e. stressors) identified include stress experienced from the "coming out" process, stress in family relations and intimate relationships, conflict over one's sexuality given society's homophobic and heterosexist attitudes toward lesbians and gay men, as well as stress from financial and work-related issues. More importantly, this study suggests that culture/ethnicity, gender, and aging, which are interconnected with one's sexual identity, play an important role in shaping the experiences of stress among lesbians and gay men.

  14. Emotion experienced during encoding enhances odor retrieval cue effectiveness.

    PubMed

    Herz, R S

    1997-01-01

    Emotional potentiation may be a key variable in the formation of odor-associated memory. Two experiments were conducted in which a distinctive ambient odor was present or absent during encoding and retrieval sessions and subjects were in an anxious or neutral mood during encoding. Subjects' mood at retrieval was not manipulated. The laboratory mood induction used in Experiment 1 suggested that anxiety might increase the effectiveness of an odor retrieval cue. This trend was confirmed in Experiment 2 by capturing a naturally stressful situation. Subjects who had an ambient odor cue available and were in a preexam state during encoding recalled more words than subjects in any other group. These data are evidence that heightened emotion experienced during encoding with an ambient odor can enhance the effectiveness of an odor as a cue to memory.

    In the current research, we examined whether re-inclusion (i.e. the change from a previous state of exclusion to a new state of inclusion) was perceived differently by people with individualistic and collectivistic cultural backgrounds. Individualists (German and Austrian participants) but not collectivists (Chinese participants) experienced re-inclusion differently than continued inclusion: While collectivistic participants did not differentiate between both kinds of inclusion, individualistic participants showed reduced fulfilment of their psychological needs under re-inclusion compared to continued inclusion. The results moreover revealed that only participants from individualistic cultures expressed more feelings of exclusion when re-included than when continually included. These exclusionary feelings partially mediated the relationship between the different states of inclusion and basic need fulfilment. © 2014 International Union of Psychological Science.

    2017-03-25

    To discuss the curative effect of the early application of the antibiotic-laden bone cement (ALBC) combined with the external fixation support in treating the open fractures of lower limbs complicated with bone defect. From December 2013 to January 2015, 36 cases of lower limb open comminuted fractures complicated with bone defects were treated by the vancomycin ALBC combined with the external fixation support, including 26 males and 10 females with an average age of 38.0 years old ranging from 19 to 65 years old. The included cases were all open fractures of lower limbs complicated with bone defects with different degree of soft tissue injuries. Among them, 25 cases were tibial fractures, 11 cases were femoral fractures. The radiographs indicated a presence of bone defects, which ranged from 3.0 to 6.1 cm with an average of 4.0 cm. The Gustilo classification of open fractures:24 cases were type IIIA, 12 cases were typr IIIB. The percentage of wound infection, bone grafting time, fracture healing time and postoperative joint function of lower limb were observed. The function of injured limbs was evaluated at 1 month after the clinical healing of fracture based on Paley evaluation criterion. All cases were followed up for 3 to 24 months with an average of (6.0±3.0) months. The wound surface was healed well, neither bone infections nor unhealed bone defects were presented. The reoperation of bone grafting was done at 6 weeks after the patients received an early treatment with ALBC, some of them were postponed to 8 weeks till the approximate healing of fractures, the treatment course lasted for 4 to 8 months with an average of(5.5±1.5) months. According to Paley and other grading evaluations of bone and function, there were 27 cases as excellent, 5 cases as good, 3 cases as ordinary. The ALBC combined with external fixation support was an effective method for early treatment to treat the traumatic lower limb open fractures complicated with bone defects. This method

    2016-01-01

    Purpose: Little is known about how permanent supported housing influences ambulatory care received by homeless persons. To fill this gap, we compared diagnoses treated in VA Greater Los Angeles (VAGLA) ambulatory care between Veterans who are formerly homeless—now housed/case managed through VA Supported Housing (“VASH Veterans”)—and currently homeless. Methods: We performed secondary database analyses of homeless-experienced Veterans (n = 3631) with VAGLA ambulatory care use from October 1, 2010 to September 30, 2011. We compared diagnoses treated—adjusting for demographics and need characteristics in regression analyses—between VASH Veterans (n = 1904) and currently homeless Veterans (n = 1727). Results: On average, considering 26 studied diagnoses, VASH (vs currently homeless) Veterans received care for more (P < .05) diagnoses (mean = 2.9/1.7). Adjusting for demographics and need characteristics, VASH Veterans were more likely (P < .05) than currently homeless Veterans to receive treatment for diagnoses across categories: chronic physical illness, acute physical illness, mental illness, and substance use disorders. Specifically, VASH Veterans had 2.5, 1.7, 2.1, and 1.8 times greater odds of receiving treatment for at least 2 condition in these categories, respectively. Among participants treated for chronic illnesses, adjusting for predisposing and need characteristics, VASH (vs currently homeless) Veterans were 9%, 8%, and 11% more likely to have 2 or more visits for chronic physical illnesses, mental illnesses, and substance use disorder, respectively. Conclusion: Among homeless-experienced Veterans, permanent supported housing may reduce disparities in the treatment of diagnoses commonly seen in ambulatory care. PMID:27343544

    2017-08-01

    This study aimed to present and test a structural model for describing and predicting the factors affecting subjective career satisfaction of nurses experiencing rotation and to develop human resources management strategies for promoting their career satisfaction related to rotation. In this cross-sectional study, we recruited 233 nurses by convenience sampling who had over 1 year of career experience and who had experienced rotation at least once at G university hospital. Data were collected from August to September in 2016 using self-reported questionnaires. The exogenous variables consisted of rotation perception and rotation stress. Endogenous variables consisted of career growth opportunity, work engagement, and subjective career satisfaction. A hypothetical model was tested by asymptotically distribution-free estimates, and model goodness of fit was examined using absolute fit, incremental fit measures. The final model was approved and had suitable fit. We found that subjective career satisfaction was directly affected by rotation stress (β=.20, p=.019) and work engagement (β=.58, p<.001), indirectly affected by rotation perception (β=.43, p<.001) through career growth opportunity and work engagement. However, there was no total effect of rotation stress on subjective career satisfaction (β=-.09, p=.270). Career growth opportunity directly and indirectly affected subjective career satisfaction (β=.29, p<.001; β=.28, p<.001). These variables accounted for 65% of subjective career satisfaction. The results of this study suggest that it is necessary to establish systematic and planned criteria for rotation so that nurses can grow and develop through sustained work and become satisfied with their career. © 2017 Korean Society of Nursing Science

    The purpose of this study was to assess electromyographic (EMG) output of the anterior tibialis (TA), medial head of the gastrocnemius (GA), rectus femoris (RF), bicep femoris (BF), and gluteus medius (GM) in experienced yogic practitioners during selected yoga asana. A secondary purpose was to examine the differences in EMG output in unilateral V. bilateral standing yoga asana. The study was a single occasion descriptive design. Thirteen healthy yoga practitioners (1 male, 12 females, average age of 37.5) with more than five years of experience were recruited. EMG activity was recorded during maximum voluntary isometric contractions (MVIC) of the TA, GA, RF, and BF using the Biodex Multijoint System ® , and GM using manual muscle testing position. Subjects then performed the following yoga asana while EMG activity was recorded: downward facing dog, half-moon, tree, chair, and warrior three pose. Each asana was held for fifteen seconds and performed three times. EMG data were band pass filtered and the root mean square was obtained. Asana data were then amplitude normalized with the subjects' MVIC data. Integrated EMG was calculated for TA, GA, RF, BF and GM, in each asana. A multilevel regression analysis was performed, and peak EMG data was compared. Analysis between muscles showed that during CH and DD EMG activity was greatest in the TA muscle compared to the other muscles, while during HM and WR the GA muscle showed the greatest activity. Analysis within muscles showed low GA, BF, and GM activity during chair pose and downward facing dog compared to half moon, tree, and warrior three, and high RF activity during chair compared to the other poses. In conclusion, there were differences in frontal and sagittal plane muscle activation between single limb and double limb poses in experienced yogic practitioners. Copyright © 2017.

    Annexin A5 is a placental anti-coagulant protein that contains four nucleotide substitutions (M2 haplotype) in its promoter. This haplotype is a risk factor for recurrent spontaneous abortion (RSA). The influence of the M2 haplotype in the gestational timing of spontaneous abortions, paternal risk and relationships with known risk factors were investigated. European couples (n = 500) who had experienced three or more consecutive spontaneous abortions, and two fertile control groups, were selected for this study. The allele frequency of M2 was significantly higher among patients who had experienced early RSA than among controls (P = 0.002). No difference was found between controls and patients who had undergone late spontaneous abortions. No difference was found between patients who had experienced RSA who had a live birth or no live births, or between patients who were positive or negative for known risk factors. Male and female partners in each group had similar allele frequencies of M2. The M2 haplotype is a risk factor for early spontaneous abortions, before the 12th week of gestation, and confers about the same relative risk to carriers of both sexes. Having one or more M2 allele(s) in combination with other risk factors further increases the RSA risk. Copyright © 2015 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

    To identify problems at different treatment points (early treatment, mid-treatment, early posttreatment, and late posttreatment) among women with ovarian cancer. Longitudinal and cross-sectional study design. An academic and community clinical cancer center in the Southeastern United States. Sixty-eight women with Stage I to IV ovarian cancer. Variables assessed included reported problems (physical, psychosocial, pain, marital, medical interaction), social support, optimism, and responses to open-ended questions. Analysis involved mixed models for longitudinal repeated measures and unpaired t tests and content analysis to describe responses to open-ended questions. Physical and psychosocial problems were greatest during early treatment and decreased throughout the treatment trajectory. Women with greater levels of social support and optimism at baseline had fewer problems over time. Women who did not have trouble paying for basics had fewer problems related to pain and psychological problems. Problems across all domains must be addressed throughout the treatment trajectory, even after chemotherapy has ended. Nurses are well positioned to refer women appropriately to social workers and clinical navigators across all domains of care and should consider systematic assessment of patient-reported problems as a routine form of practice.

    2017-03-02

    The worsening atmospheric pollution increases the necessity of air quality early warning systems (EWSs). Despite the fact that a massive amount of investigation about EWS in theory and practicality has been conducted by numerous researchers, studies concerning the quantification of uncertain information and comprehensive evaluation are still lacking, which impedes further development in the area. In this paper, firstly a comprehensive warning system is proposed, which consists of two vital indispensable modules, namely effective forecasting and scientific evaluation, respectively. For the forecasting module, a novel hybrid model combining the theory of data preprocessing and numerical optimization is first developed to implement effective forecasting for air pollutant concentration. Especially, in order to further enhance the accuracy and robustness of the warning system, interval forecasting is implemented to quantify the uncertainties generated by forecasts, which can provide significant risk signals by using point forecasting for decision-makers. For the evaluation module, a cloud model, based on probability and fuzzy set theory, is developed to perform comprehensive evaluations of air quality, which can realize the transformation between qualitative concept and quantitative data. To verify the effectiveness and efficiency of the warning system, extensive simulations based on air pollutants data from Dalian in China were effectively implemented, which illustrate that the warning system is not only remarkably high-performance, but also widely applicable.

    The Intensive Care Unit is not only a place where lives are saved; it is also a site of harm and iatrogenic injury for millions of people treated in this setting globally every year. Increasingly, hospitals admit only the sickest patients, and, while the overall number of hospital beds remains stable in the U.S., the percentage of that total devoted to ICU beds is rising. These two realities engender a demographic imperative to address patient safety in the critical care setting. This manuscript addresses the medical community’s resistance to adopting a culture of safety in critical care with regard to issues surrounding sedation, delirium, and early mobility. Although there is currently much research and quality improvement in this area, most of what we know from these data and published guidelines has not become reality in the day-to-day management of ICU patients. This manuscript is not intended to provide a comprehensive review of the literature, but rather a framework to rethink our currently outdated culture of critical care by employing Maslow’s Hierarchy of Needs, along with a few novel analogies. Application of Maslow’s Hierarchy will help propel healthcare professionals toward comprehensive care of the whole person, not merely for survival, but toward restoration of pre-illness function of mind, body, and spirit.

    Neurosurgery is a challenging field associated with high levels of mental stress. The goal of this study was to investigate the hemodynamic response of experienced neurosurgeons during aneurysm clipping surgery and to evaluate whether neurosurgeons' hemodynamic responses are associated with patients' clinical statuses. Four vascular neurosurgeons (all male; mean age 51 ± 10 years; post-residency experience ≥7 years) were studied during 42 aneurysm clipping procedures. Blood pressure (BP) and heart rate (HR) were assessed at rest and during seven phases of surgery: before the skin incision, after craniotomy, after dural opening, after aneurysm neck dissection, after aneurysm clipping, after dural closure and after skin closure. HR and BP were significantly greater during surgery relative to the rest situation (p ≤ 0.03). There was a statistically significant increase in neurosurgeons' HR (F [6, 41] = 10.88, p < 0.001), systolic BP (F [6, 41] = 2.97, p = 0.01), diastolic BP (F [6, 41] = 2.49, p = 0.02) and mean BP (F [6, 41] = 3.36, p = 0.003) during surgery. The greatest mean HR was after aneurysm clipping, and the greatest BP was after aneurysm neck dissection. Systolic, diastolic and mean BPs were significantly greater during surgical clipping for unruptured aneurysms compared to ruptured aneurysms across all stages of surgery (p ≤ 0.002); however, after adjusting for neurosurgeon experience, the difference in BP as a function of aneurysm rupture was not significant (p > 0.08). Aneurysm location, intraoperative aneurysm rupture, admission WFNS score, admission Glasgow Coma Scale scores and Fisher grade were not associated with neurosurgeons' intraoperative HR and BP (all p > 0.07). Aneurysm clipping surgery is associated with significant hemodynamic system activation among experienced neurosurgeons. The greatest HR and BP were after aneurysm neck dissection and clipping.

    PubMed

    Schreuder, J N

    1996-01-01

    Posttraumatic re-experiencing is a key symptom of earlier psychotraumatic experiences. It is important to establish whether we are dealing with nightmares or re-enactments. Posttraumatic nightmares are an expression of intrapsychic concerns and conflicts and, in and of themselves, need not impede exploratory psychotherapy. The nightmare entails both regression to the perceptual level of a small child and reactivation of early childhood anxieties. Before it is possible to work through the psychotraumatic experiences, it is necessary to contextualize the early childhood anxieties that are so closely related to the themes and anxieties of later life. If this is not possible, it will have to be decided to resort to therapy that rather covers up the experience and explores the current significance of the posttraumatic complaints. Posttraumatic re-enactments have an isolated position in the representational world and are accompanied by hyperarousal and intense vegetative symptoms, which is why they are considered an impediment to exploratory psychotherapy. Posttraumatic re-nactments require treatment of the symptoms before subsequent exploratory psychotherapy can be considered.

    2015-02-01

    This critical review evaluates the existing primary research literature to identify experienced registered nurses' attitudes, views and expectations of graduate nurses which may create a barrier for optimal graduate nurse performance. Relevant primary studies were identified by searching online databases using a wide variety of appropriate keyword combinations. Online databases including Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, PsycINFO and Google Scholar were comprehensively searched for relevant research. The selected studies were subjected to a rigorous critical appraisal to evaluate the studies and to determine if the findings were applicable to practice. A manual method of thematic analysis was conducted to highlight explicit and implicit themes from the reviewed studies. Themes were grouped and continually reduced until only essential themes remain. Themes and subthemes emerged which were then compared and contrasted to analyse results. The four major themes identified include nursing skills, inadequate preparation during academic program, attitudes and ward culture and concerns with confidence. Subthemes were identified within these categories. Findings indicate experienced registered nurses discussed themes including 'nursing skills', 'inadequate preparation during academic program', 'attitudes and ward culture' and 'concerns with confidence'. Concerns were raised including the value of traditional training versus tertiary education programs, coping with unprofessional behaviour and inadequate preparation for practice. Further research is required to fully address management of the theory-practice gap, as well as the attitudes of experienced registered nurses educated in traditional programs versus those in tertiary education programs. Nurse managers should be aware of the possible occurrence of unprofessional behaviour, and increased workplace training regarding lateral violence would assist in raising awareness regarding

    Over the past 5 years, a great deal of information about the early course of autism spectrum disorder (ASD) has emerged from longitudinal prospective studies of infants at high risk for developing ASD based on a previously diagnosed older sibling. The current article describes early ASD symptom presentations and outlines the rationale for defining a new disorder, Early Atypical Autism Spectrum Disorder (EA-ASD) to accompany ASD in the new revision of the ZERO TO THREE Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC:0–5) (in press) alternative diagnostic classification manual. EA-ASD is designed to identify children who are 9 to 36 months of age presenting with a minimum of (a) two social-communication symptoms and (b) one repetitive and restricted behavior symptom as well as (c) evidence of impairment, with the intention of providing these children with appropriately tailored services and improving the likelihood of optimizing their development.

Twenty-two experienced firefighters performed the Trondheim test simulating fire fighting tasks including work in the heat. Maximal oxygen uptake (VO2 max), heart rate (HR) and ventilation were recorded continuously. Data were compared with results obtained during a treadmill test during which the participants were dressed as smoke divers. The participants completed physical parts of the Trondheim test in ˜12 min (range: 7.5-17.4). Time to complete the test was closely related to the participant's VO2 max. HR of ˜170 beats/min and pulmonary ventilation of ˜100 L/min were higher than at lactate threshold (LT) during laboratory tests. VO2 averaged over the test's physical part was 35 ± 7 ml/min/kg, which was at the same or below the level corresponding to the participants' LT. Physically fit participants completed the test faster than less fit participants. Slower and physically less fit participants consumed more air and used more oxygen than faster and physically more fit participants. The Trondheim test is physically demanding; it distinguishes physically fit and less fit participants.

    In order to evaluate body composition and somatotype, 10 Italian experienced mountain climbers were assessed from an anthropometric point of view, before a high altitude ascent. Body mass, height, girths, skinfolds, and bone breadths were gathered and used to calculate body composition and somatotype of each subject. Means and standard deviations of the subjects' anthropometric characteristics were calculated. Mesomorphism (5.28±1.10) is the dominant somatotype component in all but one the participants, endomorphism (1.55±0.49) is low, and body fat percentage (11.76%±2.93) is low. Comparisons with athletes involved in other climbing subdisciplines highlight the specificity of elite mountain climbers anthropometry. The elite mountain climbers in our sample were predominantly mesomorphic with somatotype attitudinal mean values lower than reported for male athletes participating in free-climbing, volleyball, gymnastics, and soccer. Anthropometric characteristics may therefore play a role in mountain climbing, even though the trainable components may be more relevant than the nontrainable ones.

    More than 8% of employed RNs licensed since 2004 in the United States were educated overseas, yet little is known about the conditions of their recruitment or the impact of that experience on health care practice. This study assessed whether the labor rights of foreign-educated nurses were at risk during the latest period of high international recruitment: 2003 to 2007. Using consensus-based standards contained in the Voluntary Code of Ethical Conduct for the Recruitment of Foreign-Educated Health Professionals to the United States, this study found 50% of actively recruited foreign-educated nurses experienced a negative recruitment practice. The study also found that nurses educated in low-income countries and nurses with high contract breach fees, were significantly more likely to report such problems. If, as experts believe may occur, the nursing shortage in the United States returns around 2014, oversight of international recruitment will become critically important to delivering high-quality health care to Americans.

    To describe the prevalence of computer use problems experienced by a sample of people with arthritis, and to determine differences in the magnitude of these problems among people with rheumatoid arthritis (RA), osteoarthritis (OA), and fibromyalgia (FM). Subjects were recruited from the Arthritis Network Disease Registry and asked to complete a survey, the Computer Problems Survey, which was developed for this study. Descriptive statistics were calculated for the total sample and the 3 diagnostic subgroups. Ordinal regressions were used to determine differences between the diagnostic subgroups with respect to each equipment item while controlling for confounding demographic variables. A total of 359 respondents completed a survey. Of the 315 respondents who reported using a computer, 84% reported a problem with computer use attributed to their underlying disorder, and approximately 77% reported some discomfort related to computer use. Equipment items most likely to account for problems and discomfort were the chair, keyboard, mouse, and monitor. Of the 3 subgroups, significantly more respondents with FM reported more severe discomfort, more problems, and greater limitations related to computer use than those with RA or OA for all 4 equipment items. Computer use is significantly affected by arthritis. This could limit the ability of a person with arthritis to participate in work and home activities. Further study is warranted to delineate disease-related limitations and develop interventions to reduce them.

    Researchers are increasingly interested in understanding how food environments influence eating behavior and weight-related health outcomes. Little is known about the dose-response relationship between foodscapes and behavior or weight, with measures of food exposure having mainly focused on fixed anchor points including residential neighborhoods, schools, or workplaces. Recent calls have been made to extend the consideration of environmental influences beyond local neighborhoods and also to shift away from place-based, to people-based, measures of exposure. This report presents analyses of novel activity-space measures of exposure to foodscapes, combining travel survey data with food store locations in Montreal and Quebec City, Canada. The resulting individual activity-space experienced foodscape exposure measures differ from traditional residential-based measures, and show variations by age and income levels. Furthermore, these activity-space exposure measures once modeled, can be used as predictors of health outcomes. Hence, travel surveys can be used to estimate environmental exposure for health survey participants. Copyright © 2010 Elsevier Ltd. All rights reserved.

    In this study of the phenomenon of the postpartum period grounded theory methodology was used to investigate the experiences of first-time mothers during the first three months following their deliveries. The sample consisted of 12 primipara women and 3 multipara women. The data were generated by using unstructured interviews and field notes. Each woman was interviewed twice, the first time between 2 and 3 weeks postpartum, and the second time between 10 and 12 weeks postpartum. The final data for analysis consisted of: data generated through interviews, field notes, and the narratives of four mothers found in the non-fiction literature. Constant comparative analysis resulted in the generation of four categories and corresponding subcategories. These were: (1) Giving of Self; (2) Redefining Self; (3) Redefining Relationships; and (4) Redefining Professional Goals. The categories were not mutually exclusive. All the categories converged to provide support for the core variable 'Dialectic in Becoming a Mother'. The dialectic perspective demonstrated that, in becoming mothers, the women experienced transition, contradictions, tensions and transformations. A theoretical model was developed to show relationships among these major concepts. The findings of this study will be useful in effecting change in the provision of care to postpartum women and their families.

    Increasingly men are becoming widowed in later life due in part to a longer life expectancy. Social networks and social support are thought to help buffer the negative consequences of such later life transitions. This paper explores the personal communities of a group of older men experiencing widowhood. Qualitative in-depth interviews were conducted, September 2013-February 2014, with seven older widowers, 71-89 years of age, in North Staffordshire, UK. Interviews included personal community diagrams to identify the structure of the older men's social relationships. Data analysis comprised thematic analysis of interview transcripts and content analysis of personal community diagrams. Three overarching themes were identified from the interview data: "Personal identity and resilience assist transition," "Continuity in personal communities provides stability" and "Changes in social relationships and practices facilitate adaptation." The study identified three types of personal community among the older widowers, comprising different combinations of family, friends and others. The findings illustrate that some older widowers have very restricted personal communities which puts them at greater risk of loneliness and social isolation. The social needs of long-term carers should be addressed as isolation and loneliness can begin long before the death of a spouse. It is important to consider gender differences and preferences when designing interventions for older people in order to promote engagement, social inclusion and well-being. © 2018 John Wiley & Sons Ltd.
