Dimensions of oral care management in Texas hospitals.

PURPOSE There is a growing body of evidence that suggests improved oral health can help patient outcomes in hospitals. Yet there are indicators that oral care in hospitals is less than ideal. This study was conducted to quantify and qualify the dimensions of oral care in Texas hospitals with a focus on the dental knowledge, attitudes and practices of nurses and barriers to providing such care. METHODS A random sample of 582 registered nurses, licensed and employed in Texas, was surveyed about oral care attitudes, practices and knowledge. Frequencies and Spearman correlations were used to describe and analyze the data with SPSS. RESULTS Ninety-eight respondents returned surveys for a 16.8% response rate. Of these, 52% reported their nursing education did not ("minimally/not at all") prepare them for oral care management. However, they felt oral health was important (95%), felt responsible for oral care (79%) and assessed the oral cavity of their patients (78.6%). Although they reported being "knowledgeable" or "very knowledgeable" about oral health management (67%), their score on the knowledge questions was low (mean=51%, sd=0.132). There was not a significant correlation between the knowledge scores and education levels (ρ=0.136, p>0.05) or knowledge scores and work areas (ρ=-0.080, p>0.05). They also reported such barriers as low priority for oral care, lack of time, no mandate and the need for more resources. CONCLUSION This study revealed that nurses experienced a disconnect between feeling responsible yet somewhat incapable and/or ill-prepared to provide adequate oral care for their patients. This suggests a possible need for revising nurse education, hospital requirements and protocols for performing oral care and employing dental professionals in hospitals.
Salicylic Acid Regulates Arabidopsis Microbial Pattern Receptor Kinase Levels and Signaling[W][OPEN]

This work shows that pattern receptors are dynamically regulated by salicylic acid signaling and that pattern receptors are also needed for cell wall-based defense activated by salicylic acid. In Arabidopsis thaliana, responses to pathogen-associated molecular patterns (PAMPs) are mediated by cell surface pattern recognition receptors (PRRs) and include the accumulation of reactive oxygen species, callose deposition in the cell wall, and the generation of the signal molecule salicylic acid (SA). SA acts in a positive feedback loop with ACCELERATED CELL DEATH6 (ACD6), a membrane protein that contributes to immunity. This work shows that PRRs associate with and are part of the ACD6/SA feedback loop. ACD6 positively regulates the abundance of several PRRs and affects the responsiveness of plants to two PAMPs. SA accumulation also causes increased levels of PRRs and potentiates the responsiveness of plants to PAMPs. Finally, SA induces PRR- and ACD6-dependent signaling to induce callose deposition independent of the presence of PAMPs. This PAMP-independent effect of SA causes a transient reduction of PRRs and ACD6-dependent reduced responsiveness to PAMPs. Thus, SA has a dynamic effect on the regulation and function of PRRs. Within a few hours, SA signaling promotes defenses and downregulates PRRs, whereas later (within 24 to 48 h) SA signaling upregulates PRRs, and plants are rendered more responsive to PAMPs. These results implicate multiple modes of signaling for PRRs in response to PAMPs and SA.
Frontal-executive constructional apraxia: When delayed recall is better than copying

In assessments of visuospatial function and memory, patients are often required to copy a figure and later to reproduce that figure from memory. Whereas most people perform better on a copying task than when drawing from memory, in this study we describe an unusual pattern of performance in which patients are better at drawing from memory than copying. Consecutive patients in a neurocognitive disorders clinic were given a battery of clinical cognitive tests that included copying a figure of intersecting pentagons and then drawing the figure from memory. Patterns of drawing performance at the two time points were compared to the profile of other cognitive deficits. Results: A subgroup of four patients with frontal dysfunction showed marked improvement in drawings at a delay compared to copying. Prior studies have indicated that most patients have declines in drawing performance at a delay. The unusual pattern of better performance at a delay compared to an initial copy occurred in patients with frontal dysfunction. These patients’ visuoconstructive deficit and subsequent improvement could be related to either a failure to disengage when a model is present, to memory consolidation with increased reliance on top-down processing in the delay condition, or to relative preservation of global versus local aspects of a stimulus in memory. The addition of a task to assess drawing after a delay to a standard clinical screening battery such as the Mini-Mental Status Examination (MMSE) provides the opportunity to evaluate this phenomenon that may be indicative of frontal-executive dysfunction.
Impact of coatings on the quality factor of a quartz crystal resonator at liquid helium temperature

Effects of coatings on the quality factor of quartz crystal resonators operating at liquid helium temperature are analyzed. A first set of tests demonstrates the effects of gold and chromium electrodes at low temperature. The second set of tests involves a multilayer tantala/silica coating used to reach an extreme reflectance on mirrors such those used in optical cavities or Michelson interferometers. Mechanical losses are measured and discussed from the theoretical model the most frequently used.
Reduced immunoreactivity of adenylyl cyclase in dementia of the Alzheimer type

THE amounts of three adenylyl cyclase (AC) subtypes In membranes from brain obtained post-mortem from patients with dementia of Alzheimer type (DAT) and controls were studied by Western blotting using poly-clonal antibodies. AC subtypes were characterized by preabsorption by complementary peptides, species difference, tissue distribution and by using AC-VI-transfected cells. Immunoreactivities of AC-I and AC-II subtypes, which are predominant in brain tissue were decreased 40.5% (p < 0.02) and 52.0% (p < 0.02), respectively in DAT compared with controls. No significant difference in immunoreactivity of AC-V/VI subtypes distributed in various other tissues was observed. Our results are the first to indicate that reduced levels of brain-specific AC subtypes occur in DAT.
Stop Blaming the Victim: A Meta-Analysis on Rape Myths

Although male rape is being reported more often than before, the majority of rape victims continue to be women. Rape myths—false beliefs used mainly to shift the blame of rape from perpetrators to victims—are also prevalent in today’s society and in many ways contribute toward the pervasiveness of rape. Despite this, there has been limited consideration as to how rape prevention programs and policies can address this phenomenon, and there is no updated information on the demographic, attitudinal, or behavioral factors currently associated with rape myths. This research aimed to address this gap by examining the correlates of rape-myths acceptance (RMA) in published studies. A total of 37 studies were reviewed, and their results were combined using meta-analytic techniques. Overall, the findings indicated that men displayed a significantly higher endorsement of RMA than women. RMA was also strongly associated with hostile attitudes and behaviors toward women, thus supporting feminist premise that sexism perpetuates RMA. RMA was also found to be correlated with other “isms,” such as racism, heterosexism, classism, and ageism. These findings suggest that rape prevention programs and policies must be broadened to incorporate strategies that also address other oppressive beliefs concurrent with RMA. Indeed, a renewed awareness of how RMA shapes societal perceptions of rape victims, including perceptions of service providers, could also reduce victims’ re-victimization and enhance their coping mechanisms.
Catastrophic Health Expenditure of Chronic Diseases: Evidence from Hamadan, Iran

Background: Chronic noncommunicable diseases (NCDs) could increase the risk of catastrophic health expenditure (CHE). The present study aims to analyze CHE among households with and without chronic NCDs in Hamedan. Methods: In this cross-sectional study, 780 households’ patients, who were being discharged from hospitals in Hamedan, were selected using a proportional stratified random sampling method. Required data were collected through interview and observation using World Health Organization standard questionnaire. A household with chronic NCDs is defined as the one with ≥1 chronic disease patient. Both descriptive and analytical statistics, as well as different approaches and thresholds, were used to study CHE among households. Results: The households with chronic disease had higher incidence and intensity of CHE in all approaches and threshold. This result was shown through distributive-sensitive measures. The Regression analysis revealed that lower economic status, lower household size, and high utilization of health care were associated with the CHE incidence and intensity in the households with chronic NCDs in Hamedan. Conclusions: There is a high degree of CHE were caused by chronic NCDs. By thoughtful reconsideration in health-care financing, along with addressing relevant socioeconomic factors, the health system of Iran could cope with financial adversities caused by chronic NCDs.
Histopathological study of salivary gland tumors

Context: The salivary glands are the site of origin of a wide variety of neoplasms and are also relatively uncommon. The histopathology of these tumors is said to be the most complex and diverse of any organ in the body. The incidence of salivary gland tumors (SGTs) is claimed to be influenced by geographical and racial factors. Histopathological diagnosis plays a major role in the diagnosis of these neoplasms, with very few contribution using special stains, immunohistochemistry and cytogenetic studies. Aims: Aimed at understanding the epidemiological pattern of these tumors and to compare our findings with reports done elsewhere. Settings and Design: This is a retrospective study done at Pathology Department a Postgraduate Teaching Hospital, Tertiary Care Centre in Bagalkot, Karnataka, India. All the cases of SGTs, which had been recorded in a 3-year period from 2009 to 2012, were enrolled in the study. Subjects and Methods: Clinical data were recorded and analyzed with respect to gender, age, site and histopathologic type. Results: Data of 59 cases of SGTs were recorded, of which 43 (69.16%) cases were classified as benign tumors and 16 (22.39%) cases as malignant tumors. Male to female ratio (M/F) and the mean age of patients were 1:1.8 and 43 years, respectively. Pleomorphic adenoma (60.71%) and adenoid cystic carcinoma (14.94%) were the most common benign and malignant neoplasms. Conclusions: Although the SGTs encountered were similar in most of their characteristics to those reported in India and other countries, some differences such as relative frequency, age and gender prevalence were discovered.
A Knowledge-centric Examination of Signaling and Screening Activities in the Negotiation for Information Systems Consulting Services

: In many professional exchanges, information asymmetry is bilateral, which means that both parties hold information that the other party lacks and, as a result, both parties have the means to be opportunistic. To counter this asymmetry, both parties signal and screen information as they negotiate a consulting engagement. In this paper, we report on how a professional service provider and recipient typically use signaling and screening. The findings highlight that both parties signal and screen and withhold information and that the extent of project knowledge (tacit or explicit) affects how they do so. Tacit knowledge-centric projects have more signaling and screening events than explicit knowledge-centric projects but many of these signals actually increase the amount of information asymmetry.
Isolation and characterization of substance P‐containing dense core vesicles from rabbit optic nerve and termini

In neurons, neuropeptides and other synaptic components are transported down the axon to the synapse in vesicles using molecular motors of the kinesin family. In the synapse, these neuropeptides are found in dense core vesicles (DCVs), and, following calcium‐mediated exocytosis, they interact with receptors on the target cell. We have developed a rapid, large‐scale technique for purifying peptide‐containing DCVs from specific nuclei in the central nervous system. By using differential velocity gradient and equilibrium gradient centrifugation, neuropeptide‐containing DCVs can be separated by size and density from optic nerve (ON) and its termini, the lateral geniculate nuclei and the superior colliculi. Isolated DCVs contain neuropeptides (substance P and brain‐derived neurotrophic factor), synaptic vesicle (SV) membrane proteins (SV2, synaptotagmins, synaptophysin, Rab3 and synaptobrevin), SV‐associated proteins (α‐synuclein), secretory markers for DCVs previously isolated (secretogranin II), and β‐amyloid precursor protein. By using electron microscopic techniques, DCV were also visualized and shown to be immunoreactive for neuropeptides, neurotrophins, and SV membrane proteins. Because of the interesting group of physiological and potentially pathophysiological proteins associated with these vesicles; this isolation procedure, applicable to other CNS nuclei, should represent an important research tool.

Topical Antiinflammatory Activity of Essential Oil of Lippia sidoides Cham: Possible Mechanism of Action

This work reports the chemical composition of the essential oil of Lippia sidoides (EOLS) and evaluation of the topical effect of EOLS and thymol against different irritant agents in vivo. The essential oil was obtained by hydrodistillation, and gas chromatography/mass spectrometry analysis identified the main constituents: thymol (84.9%) and p‐cymene (5.33%). The antiinflammatory activity was evaluated using the mouse models of acute ear inflammation induced by croton oil, arachidonic acid, phenol or histamine, and chronic inflammation induced by croton oil. The topical application of EOLS or thymol at a dose of 2 mg/ear significantly reduced (p < 0.001) ear edema induced with arachidonic acid by 45.1% and 47.4% and reduced ear edema induced with phenol by 33.2% (p < 0.05) and 54.7% (p < 0.01) in acute ear edema. However, a proinflammatory effect of EOLS and thymol was evidenced when it was applied for more than 1 day. There were no statistical differences in antiedematogenic activity between EOLS and thymol. In conclusion, the results indicate that thymol is the constituent responsible for the topical antiinflammatory activity of EOLS. Thus, these findings could justify the popular use of L. sidoides by alternative medicine, but chronic use has an inflammatory effect. Copyright © 2012 John Wiley & Sons, Ltd.
Streak breakdown instability in pipe Poiseuille flow

This work is devoted to the study of the stability of Hagen–Poiseuille flow or pipe flow. The analysis is focused on the streak breakdown process by which two-dimensional streamwise-independent finite amplitude perturbations transiently modulate the basic flow leading to a profile that contains saddle points and is linearly unstable with respect to very small streamwise-dependent perturbations. This mechanism is one possible route of transition to turbulence in subcritical shear flows. The exploration is carried out for initial disturbances of different finite amplitudes and axial and azimuthal periodicity. This study covers a wide range of Reynolds numbers and the double threshold curve obtained for transition is consistent with experimental observations.
Association of the Extent of Resection With Survival in Glioblastoma: A Systematic Review and Meta-analysis.

Importance Glioblastoma multiforme (GBM) remains almost invariably fatal despite optimal surgical and medical therapy. The association between the extent of tumor resection (EOR) and outcome remains undefined, notwithstanding many relevant studies. Objective To determine whether greater EOR is associated with improved 1- and 2-year overall survival and 6-month and 1-year progression-free survival in patients with GBM. Data Sources Pubmed, CINAHL, and Web of Science (January 1, 1966, to December 1, 2015) were systematically reviewed with librarian guidance. Additional articles were included after consultation with experts and evaluation of bibliographies. Articles were collected from January 15 to December 1, 2015. Study Selection Studies of adult patients with newly diagnosed supratentorial GBM comparing various EOR and presenting objective overall or progression-free survival data were included. Pediatric studies were excluded. Data Extraction and Synthesis Data were extracted from the text of articles or the Kaplan-Meier curves independently by investigators who were blinded to each other's results. Data were analyzed to assess mortality after gross total resection (GTR), subtotal resection (STR), and biopsy. The body of evidence was evaluated according to Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria and PRISMA guidelines. Main Outcome and Measures Relative risk (RR) for mortality at 1 and 2 years and progression at 6 months and 1 year. Results The search produced 37 studies suitable for inclusion (41 117 unique patients). The meta-analysis revealed decreased mortality for GTR compared with STR at 1 year (RR, 0.62; 95% CI, 0.56-0.69; P < .001; number needed to treat [NNT], 9) and 2 years (RR, 0.84; 95% CI, 0.79-0.89; P < .001; NNT, 17). The 1-year risk for mortality for STR compared with biopsy was reduced significantly (RR, 0.85; 95% CI, 0.80-0.91; P < .001). The risk for mortality was similarly decreased for any resection compared with biopsy at 1 year (RR, 0.77; 95% CI, 0.71-0.84; P < .001; NNT, 21) and 2 years (RR, 0.94; 95% CI, 0.89-1.00; P = .04; NNT, 593). The likelihood of disease progression was decreased with GTR compared with STR at 6 months (RR, 0.72; 95% CI, 0.48-1.09; P = .12; NNT, 14) and 1 year (RR, 0.66; 95% CI, 0.43-0.99; P < .001; NNT, 26). The quality of the body of evidence by the GRADE criteria was moderate to low. Conclusion and Relevance This analysis represents the largest systematic review and only quantitative systematic review to date performed on this subject. Compared with STR, GTR substantially improves overall and progression-free survival, but the quality of the supporting evidence is moderate to low.
Long term results of percutaneous fixation of proximal humerus fractures

Background: Proximal humerus fracture in elderly osteoporotic patients usually leads to severe displaced and multifragmentary fractures. Associated comorbidities may limit surgical options and conservative treatment is commonly indicated, however, with variable results. In most cases, surgery is the treatment of choice in order to restore anatomical integrity, and allow early functional recovery. Several techniques were used over the years, each with specific indication. Percutaneous pinning after closed reduction, a mini-invasive technique and fixation by use of K-wires is not preferred commonly. We present our experience with this approach, focusing on its indications and advantages. Patients and Methods: A study group of 41 consecutive patients with a mean age of 65.5 years were evaluated clinically (VAS, Constant-Murley score, range of motion), and with radiological analysis: 35 patients finally completed a minimum followup of 24 months. Results: K-wires were removed after a mean interval of 4 weeks. Clinical and radiographic healing occurred in a mean time of 8.2 weeks in all fractures but one, with improvements in mean Constant-Murley score of 87.6 points, mean VAS of 2.3. In 33 patients, the reduction was considered satisfactory. In two cases, reduction was poor, but the patients however presented acceptable functional outcome. Conclusions: Percutaneous pinning may represent a suitable option of treatment for 2-or 3-part proximal humerus fractures in selected subjects.
On The Generalized Fibonacci And Pell Sequences By Hessenberg Matrices

In this paper, we consider the generalized Fibonacci and Pell Sequences and then show the relationships between the generalized Fibonacci and Pell sequences, and the Hessenberg permanents and determinants. 1. Introduction The Fibonacci sequence, fFng ; is de ned by the recurrence relation, for n 1 Fn+1 = Fn + Fn 1 (1.1) where F0 = 0; F1 = 1: The Pell Sequence, fPng ; is de ned by the recurrence relation, for n 1 Pn+1 = 2Pn + Pn 1 (1.2) where P0 = 0; P1 = 1: The well-known Fibonacci and Pell numbers can be generalized as follow: Let A be nonzero, relatively prime integers such that D = A +4 6= 0: De ne sequence fung by, for all n 2 (see [17]), un = Aun 1 + un 2 (1.3) where u0 = 0; u1 = 1: If A = 1; then un = Fn (the nth Fibonacci number). If A = 2; then un = Pn ( the nth Pell number). An alternative is to let the roots of the equation t At 1 = 0 be, for n 0 un = n n : The sequence fung have studied by several authors (see [6], [1]). The following identities can be found in [6], [1]:
The Effect of Posture on the Response to Atrioventricular Synchronous Pacing in Patients with Underlying Cardiovascular Disease

In order to determine whether the hemodynamic benefit of atrioventricular synchronous pacing is maintained in the upright position, 14 patients with dual chamber pacemakers were paced in VVI mode and DDD mode in both the supine and standing position. The hemodynamic response was assessed by measuring the velocity time integral derived from the pulsed‐wave Doppler signal in the left ventricular outflow tract during VVI pacing and dual chamber pacing at three different AV delays (125, 200, 250 ms). In the supine position, the velocity time integral during VVI pacing was 14.6 ± 3.0 cm and this increased during DDD pacing at all three AV delays (17.7 ± 3.3, 17.9 ± 3,0, 17.5 ± 3.5 cm). In the upright position, the velocity time integral during VVI pacing was 12.9 ± 3.5 cm and this increased with DDD pacing (15.5 ± 3.3, 15. 1 ± 4.0, 15.1 ± 3.9 cm). It was concluded that although stroke volume decreases when assuming the upright position, the beneficial response to dual chamber pacing is maintained and equals that observed in the supine position.
A case study in seeding collaboration transformation with experience themes

Collaboration at Intel is currently in a stage of transformation with increased focus on using social computing and other technologies to boost collaboration and productivity. This transformation requires a shift in the services IT provides and a solid understanding of the expectations that employees have of both their technology and the larger environment in which collaboration happens. At the same time, we have been given the mandate to Be Bold, and Act Fast, leaving little time for upfront user research and requiring us as UX professionals to rethink how we enable project teams to be more effective within this new reality. One approach that is being used within IT to help product design teams move more quickly is experience themes, which package available user research for easier reuse. The collaboration portfolio has been an early adopter and used experience themes for the last year to help define the desired collaboration experience from upfront strategy and back-end architecture to the design of individual products. We will share learnings on how to best use these concepts and discuss the benefits of having a re-usable, over-arching experience vision in guiding product decision-making.
