Risk Factors and Outcomes Associated With Hospital-Onset Peripheral Intravenous Catheter–Associated Staphylococcus aureus Bacteremia

Abstract Background Peripheral venous catheters (PVCs) are common in hospitals, but the literature surrounding PVC-associated bacteremia is lacking. We describe incidence rates, risk factors, and outcomes related to PVC-associated Staphylococcus aureus bacteremia (SAB), a common cause of hospital-onset (HO) SAB. Methods This is a retrospective case–control study conducted at a 537-bed teaching community hospital during 2015–2016. Cases were adult inpatients with HO SAB with infectious diseases documentation of the PVC as the only source of bacteremia. Cases were matched 1:2 with controls on approximate PVC insertion date, age, mortality prediction score, and insurance type. Odds ratios (ORs) were estimated using conditional logistic regression. PVC utilization was estimated by a point-prevalence survey from July 2017. Results Of 205 SAB episodes, 160 were community-onset and 45 were HO; 16 (36%) HO cases were PVC-associated. Cases (n = 16) were more likely than controls (n = 32) to have a PVC placed in the antecubital area (odds ratio [OR], 11.9; 95% confidence interval [CI], 1.5–95.7; P = .02) and PVC duration ≥4 days (OR, 4.0; 95% CI, 1.1–15.2; P = .04). The point prevalence of at least 1 PVC in adult inpatients was 86%, and the incidence density of HO PVC–associated SAB was 0.15 per 1000 PVC-days. The mean length of stay for cases was 13.2 days. All cases successfully completed parenteral antibiotics with a mean treatment length of 23.6 days. Conclusions PVC-associated SAB is a common cause of HO SAB that results in significant morbidity. PVC placement in the antecubital area and line duration should be minimized to reduce HO SAB.
Apical lymph node dissection of the inferior mesenteric artery with preservation of left colic artery in colorectal cancer

Background: Nowadays, surgery for colorectal cancer has been standardized both ways in open and laparoscopic approaches but there are still debates regarding the level of ligation of the IMA at its origin from aorta (high ligation) or below the origin of left colic artery (low ligation). The technique of apical lymph node dissection with preservation of LCA has the advantage of both, better lymph node harvest and lower postoperative complications. It is controversial whether a high or low ligation of the inferior mesenteric artery (IMA) is superior. The former allows an extended lymph node clearance whereas the latter preserves the distal vascular supply via the left colic artery (LCA). Apical lymph node dissection of the IMA (ALMA) harvests nodal tissue along the IMA proximal to the LCA whilst performing a low ligation. This anatomically replicates the oncological benefit of high ligation and the vascular preservation of low ligation. This study evaluates the nodal yield of ALMA and the short-term outcome of this technique.Methods: Author retrospectively studied 40 patients with operable sigmoid and rectal cancer who admitted to general surgery department in Menoufia University Hospitals from May 2016 to May 2018. All patient underwent curative surgical resection with ALMA. The lymph node yield from the dissection (the ALMA specimen) was compared with the total lymph node yield. Data on the LCA anatomy, time required to perform ALMA, complications and postoperative recovery were evaluated.Results: Results ALMA was successful in 36 patients. Median postoperative hospitalization was 5 (2-26) days without ALMA-related morbidity or mortality. The median lymph node yield was 20 (9-41) and a median of 14.3 (0-80)% were harvested with ALMA. Two patients not having neoadjuvant chemoradiotherapy had fewer than 12 lymph nodes, excluding nodes harvested from ALMA. The average time required for ALMA was 20min.Conclusions: ALMA (lymph node dissection around the IMA preserving the root of the IMA and LCA) was feasible by this method without compromising operation time, blood loss or the number of harvested lymph nodes with accepted rate of postoperative complications.
Original articles.

Background: While many are familiar with postpartum depression , the phenomenon of postpartum post-traumatic stress disorder (PTSD) is less well known and investigated. Objectives: To assess the prevalence of postpartum PTSD in a cohort of women in Israel and examine factors affecting its development. methods: Eighty-nine women completed several ratings immediately post-delivery and after a month. Factors examined related to the pregnancy, childbirth expectations, and delivery. Rating scales comprised evaluations of attachment, personality, PTSD, and demographic variables. results: The prevalence of post-partum PTSD was 3.4% (complete PTSD), 7.9% nearly complete PTSD, and 25.9% significant partial disorder. Women who developed PTSD symptoms had a higher prevalence of " traumatic " previous childbirth, with subsequent depression and anxiety. They also reported more medical complications and " mental crises " during pregnancy as well as anticipating more childbirth pain and fear. Instrumental or cesarean deliveries were not associated with PTSD. Most of the women who developed PTSD symptoms delivered vaginally, but received fewer analgesics with stronger reported pain. Women with PTSD reported more discomfort with the undressed state, stronger feelings of danger, and higher rates of not wanting additional children. conclusions: The study results indicate the importance of inquiring about previous pregnancy and birthing experiences and the need to identify at-risk populations and increased awareness of the disorder. The importance of addressing anticipatory concerns of pain prior to delivery as well as respecting dignity and minimizing the undressed state during childbirth should not be underestimated. A short questionnaire following childbirth may enable rapid identification of symptoms relevant to PTSD.
Ventriculoperitoneal Shunt Outcomes of Normal Pressure Hydrocephalus: A Case Series of 116 Patients

Background Permanent cerebrospinal fluid (CSF) diversion with a ventriculoperitoneal shunt (VPS) is a treatment option for patients with normal pressure hydrocephalus (NPH). Objectives Herein, we examine the outcomes, complication rates, and associations between predictors and outcomes after VPS in patients with NPH. Methods This was a retrospective review of 116 patients (68 males, 48 females) with NPH who underwent VPS placement from March 2008 to September 2017 after demonstrating objective and/or subjective improvement after a lumbar drain trial. The Chi-square test of independence was used to examine associations between predictors and clinical improvement after shunting. Complications associated with the VPS procedure were recorded. Results The mean age was 77 years (range 52-93). The mean duration of disturbance in gait, cognition, and continence were 29, 32, and 28 months, respectively. Of the 116 patients, 111 followed up at two weeks; of these, improvement in gait, incontinence, and cognition were reported in 72, 20, and 23 patients, respectively. Gait improved more than incontinence or cognition. A shorter duration of gait disturbance predicted an improvement in gait after shunting (p<0.01). Being on a cognition-enhancing medication predicted an improvement in cognition and/or incontinence after shunting (p<0.05). Complications included misplaced proximal catheters (n=6), asymptomatic catheter tract hemorrhages (n=3), bilateral hygromas (n=7), subdural hematomas (SDH) (n=5), and CSF leak (n=1). Conclusion VPS placement in patients with NPH is well-tolerated and associated with improved outcomes at least in the short-term follow-up (<6 months). A shorter duration of gait disturbance and being on a cognition-enhancing medication are associated with greater improvement after VPS.
The inheritance of anther extrusion in hexaploid wheat and its relationship to Fusarium head blight resistance and deoxynivalenol content

With 6 figures and 3 tables Abstract Anther extrusion (AE) has been suggested as one of the resistance mechanisms to Fusarium head blight (FHB) in wheat, but not well investigated. The objectives of this study were to assess AE in the double haploid population ‘Arina’ × ’NK93604’, evaluate its relationship both with FHB and deoxynivalenol (DON) accumulation, and map quantitative trait loci (QTLs). AE was studied in 2005−2007 and its relationship to FHB and DON content was analysed with data from Fusarium culmorum inoculations in 2001–2003 and with Fusarium graminearum in 2007. AE showed continuous distribution, transgressive segregation, minimal genotype × year interactions and was highly heritable (H2 = 0.91). Mean AE showed highly significant negative correlations both with FHB (r = −0.53 to −0.69, P = 0.0001) and DON (r = −0.39 to −0.46, P = 0.0001). Composite interval mapping identified 4 QTLs for mean AE over 2 years that explained 53.6% of the total phenotypic variation. The phenotypic variance explained by the QTLs on chromosomes 1AL, 1BL, 4DL and 6AS varied from 7.4% to 18.3%. This is the first report describing QTLs for AE and to look systematically for association of AE with FHB and DON.
OBSERVED CHANGES IN DAILY RAINFALL EXTREME ALONG THAILAND'S COASTAL ZONES

Abstract Trends in daily rainfall extreme along Thailand's coastal zones were examined, based on 28 high-quality series of daily rainfall data observed at the stations along the Andaman Sea Coast (ASC), the Gulf of Thailand's western coast (GoTw) and the Gulf of Thailand's eastern coast (GoTe). A set of core climate extreme indices recommended by the WMO-CCL/CLIVAR Expert Team on Climate Change Detection, Monitoring and Indices (ETCCDMI) that measures different aspects of rainfall extreme events such as wetness and dryness conditions, frequency and intensity rainfall events was calculated. Analysis of these indices revealed notable changes in rainfall extreme events along Thailand's coastal zones in the recent decades. On the ASC, significant changes were characterized by an overall decrease in total rainfall amounts accompanied by a coherent reduction of heavy and intensity rainfall events. However, extreme rainfall changes on the GoTw were marked by more intense daily rainfall associated with a significant decrease in the number of rainy days. These changes indicate that GoTw has experienced a wetter condition and increases in magnitude and frequency of more intense rainfall events. For GoTe, changes in extreme rainfall events were relatively mixed with significant positive and negative trends. Additional analyzes of the PDFs for all stations before and after 1990 indicated a significant shift in the distribution towards a decline in dryness conditions. This observed change provides a vital clue of shift in extreme rainfall characteristics along Thailand's coastal zones under an anthropogenic-induced warmer regime and fluctuations of regional climate variability. Our findings suggest that coastal areas of Thailand will be disproportionately exposed to increasing risks of different extreme rainfall-driven disasters. Anticipated impacts including increases in inland flash flood, more frequent coastal flooding, coastal erosion and severe water shortage will introduce devastating pressures, and intensify other existing social-economic problems on natural resources and environment in the coastal areas of 50 Thailand. Therefore, further assessment on vulnerability and risk is needed to shed more light on how to cope with and adapt to such adverse impacts. Such knowledge is important for building sustainable, resilient coastal communities, and effective disaster risk and coastal managements.

Effects of temperature, sorbitol, alanine and diapause hormone on the embryonic development in Bombyx mori: in vitro tests of old hypotheses

Abstract. An in vitro culture method is described in which embryonic development in Bombyx mori is traced at various temperatures and treatments. The results show that the induction, intensification and termination of diapause are distinct processes. Prediapause embryos, explanted from 40‐h‐old diapause‐destined eggs and cultured in Grace's medium, continue to develop to the appendage‐formation stage without arrest, which indicates that the isolated embryos have not entered diapause, whereas the development of embryos from diapausing eggs (15 days after being laid) is significantly slower. The rate of development of embryos dissected from diapause eggs increases during chilling (5 °C) and incubation (at 25 °C) gradually during chilling and dramatically at 25 °C. The in vitro experiments also reveal that sorbitol directly inhibits the development of embryos explanted from diapausing eggs but has no affect on the development of embryos from prediapause eggs. Neither alanine nor diapause hormone prevent isolated embryos from developing.
Arsenic Speciation in Environmental and Biological Samples From Argentina: Relationship Between Natural and Anthropogenic Levels and Human Health Status.

Total arsenic (As) in environmental (water, soil, sediment) and biological (scalp hair, urine) samples collected from naturally As-rich areas in Argentina (San Juan and La Pampa) was determined by inductively coupled plasma mass spectrometry (ICP-MS) in collision cell mode. Arsenic levels in surface (11-133 μg/1 As) and groundwater (3-1326 μg/1 As) typically exceeded the World Health Organisation (WHO) guideline value of 10 μg/1 As for potable waters, the Argentinean national drinking water standard of 50 μg/1 As and in some cases the Food and Agriculture Organisation (FAO) of the United Nations irrigational water limit of 100 μg/1 As. A naturally low arsenic region, namely Rio Negro, was sampled to provide comparative data for the As-rich areas in Argentina. The development of a method for the in situ collection, preservation and separation of the arsenic species; arsenite (AsIII), arsenate (AsV), monomethylarsonic acid (MAV) and dimethylarsinic acid (DMAV) in natural waters was undertaken utilising solid phase extraction (SPE) cartridges. The assessment of arsenic species by SPE revealed the presence of the organoarsenicals MAV and DMAV up to 79 μg/1 (33% of the total arsenic) in San Juan (Encon) groundwater, which are not typically observed in literature data for corresponding water types. The major arsenic species in natural waters were the more toxic AsIII and AsV species. Surface soils and river sediments (dried and sieved) from San Juan and La Pampa Provinces had levels of 5-35 mg/kg As (dry weight, d.w.) and 6-32 mg/kg As (d.w.), respectively; comparative to reported world-wide values ranging from 0.4 to 70 mg/kg As (d.w.). The predominant arsenic species in Argentinean soils was AsV, with no detectable methylated forms. Sequential fractionation of soils and sediments confirmed the extractable forms of arsenic to be in the order: residual > exchangeable > bound to Fe and Mn oxides > bound to organic matter and sulphides. The assessment of washed human scalp hair and urine as potential biomarkers for arsenic exposure showed high arsenic levels in participants from San Juan and La Pampa (As-rich areas). Arsenic speciation of washed scalp hair revealed the presence of AsIII and AsV, whereas urinary arsenic species were principally organoarsenicals (DMAV > MAV > arsenobetaine, AB). The metabolic biotransformation of arsenic in exposed individuals (based on washed scalp hair and urine data) indicates a possible reduction in arsenic toxicity. This research highlights the potential sources of natural and anthropogenic arsenic in the Argentinean environment and the likely toxicological effects on the exposed population.
Continuous Reinforcement Algorithm and Robust Economic Dispatching-Based Spot Electricity Market Modeling considering Strategic Behaviors of Wind Power Producers and Other Participants

In a spot wholesale electricity market containing strategic bidding interactions among wind power producers and other participants such as fossil generation companies and distribution companies, the randomly fluctuating natures of wind power hinders not only the modeling and simulating of the dynamic bidding process and equilibrium of the electricity market but also the effectiveness about keeping economy and reliability in market clearing (economic dispatching) corresponding to the independent system operator. Because the gradient descent continuous actor-critic algorithm is demonstrated as an effective method in dealing with Markov’s decision-making problems with continuous state and action spaces and the robust economic dispatch model can optimize the permitted real-time wind power deviation intervals based on wind power producers’ bidding power output, in this paper, considering bidding interactions among wind power producers and other participants, we propose a gradient descent continuous actor-critic algorithm-based hour-ahead electricity market modeling approach with the robust economic dispatch model embedded. Simulations are implemented on the IEEE 30-bus test system, which, to some extent, verifies the market operation economy and the robustness against wind power fluctuations by using our proposed modeling approach.

Electrical Responses of the Olfactory Epithelium of Atlantic Salmon (Salmo salar)

Multiunit spike activity was recorded from the olfactory mucosa of Atlantic salmon (Salmo salar) using metal-filled glass microelectrodes. A number of simple and complex solutions were tested for stimulatory effectiveness. Amino acids as a class of compounds were highly stimulatory; little or no response was obtained to a variety of simple sugars, n-aliphatic acids, alcohols, or amino-substituted alcohols. An increase in asynchronous spike activity was evoked by low concentrations of amino acids and oscillatory activity was evoked by higher concentrations of amino acids. Brief treatment of the epithelium with dilute solutions of HgCl2 blocked the chemosensitivity of the receptors.
Multiaspect‐based opinion classification model for tourist reviews

Tourist reviews on social media websites reflect the tourist's opinions concerning various aspects of a tourist place or service (e.g., “comfortable room” and “terrible service” in hotel reviews). Extracting these aspects from reviews is a challenging task in opinion mining. Therefore, aspect‐based opinion mining has emerged as a new area of social review mining. Existing approaches in this area focus on extracting explicit aspects and classification of opinions around these aspects. However, the implicit and coreferential aspects during aspect extraction are often neglected, and the classification of multiaspect opinions is relatively less emphasized in prior art. In this paper, we propose a model, namely, “enhanced multiaspect‐based opinion classification” that addresses existing challenges by automatically extracting both explicit and implicit aspects and classifying the multiaspect opinions. In this model, first, a probabilistic co‐occurrence‐based method is proposed that utilizes the co‐occurrence between aspects and sentiment words to identify the coreferential aspects and merge them into groups. Second, an implicit aspect extraction method is proposed that associates the sentiment words with suitable aspects to build an aspect‐sentiment hierarchy. Third, a multiaspect opinion classification approach is proposed that employs multilabel classification algorithms to classify opinions into different polarity classes. The effectiveness of the proposed model is evaluated by conducting experiments on benchmark and real‐world datasets. The experimental results revealed the supremacy of multilabel classifiers by achieving 90% accuracy per label on classification when extracting 87% domain‐relevant aspects. A state‐of‐the‐art performance comparison is conducted that also verifies the advantages of the proposed model.
CroMatcher - results for OAEI 2016

Ontology matching plays an important role in the integration of heterogeneous data sources that are described by ontologies. In order to find correspondences between entities of different ontolog ies, a matching system has to be built. CroMatcher is an ontology matching system that consists of several string and structural basic matchers. As individual basic matcher computes similarity between entities using information obtained from one or more co mponents of the entire ontology, all individual matching results need to be aggregated in order to achieve the better final matching results of compared ontologies. The CroMatcher system uses weighted aggregation method that automatically determines the we ighting factors of each basic matchers considering quality of its matching result. Also, the system uses iterative final alignment method that selects appropriate correspondences between entities of compared ontologies from the aggregated matching results. This is the third time CroMatcher has been involved in the OAEI campaign. The system is upgraded by introducing two new basic matchers that improved the matching results at this OAEI campaign. CroMatcher achieved excellent matching results for the three o ntology matching tracks in which it participated
