The Eﬀectof Benson Relaxation on the Anxiety of Patients under Radial Angiography: A Randomized ClinicalTrial

Background: Angiography is the gold standard test for the diagnosis of coronary artery disease; however, more than 82% of patients have stress and anxiety before they undergo angiography, which significantly effects the diagnostic results. One of the common complications of the angiography method through the radial artery is the occurrence of arterial spasm that is seen more in patients with severe anxiety. The current researchers believe that using Benson relaxation is effective in reducing the patient’s anxiety. Objectives: This study was designed to evaluate the Benson relaxation method in patients undergoing radial angiography. Methods: This study was a clinical trial, which was performed on 60 candidate patients undergoing coronary angiography by radial method at Baqiyatallah Hospital during year 2017 (N = 60). The samples were randomly allocated to two groups, intervention and control. The information gathering tools were demographic questionnaire, the Beck Anxiety Inventory (BAI), and hemodynamic variables checklist. Data analysis was done with the SPPSS V16 software using Kolmogorov Smirnov test, Mann Whitney test, and
The Role of Entitlement in Formatting Preferences Across Requesters and Recipients

ABSTRACT Requesting plays a key role in human communication. One can request the same thing in multiple ways (e.g., “Pass the salt” vs. “Could you pass the salt? ”). How do speakers determine which request form to produce? And how does this choice affect a recipient’s evaluation of a request? Previous analyses of naturalistic conversations suggest that a speaker’s entitlement – their expectations that the recipient of a request is able and willing to fulfill it – can influence their formatting decisions. However, the role of entitlement in format selection has not been tested experimentally, nor is it known how a requester’s entitlement impacts a recipient’s evaluation of a request form. Across several online experiments, we asked whether manipulations of a speaker’s entitlement influenced formatting preferences across requesters and recipients. While requesters robustly recognized normative mappings between entitlement and request formatting (Experiment 2), they did not necessarily follow these mappings unprompted (Experiments 1–1b); instead, they tended to produce modal interrogative requests (“Can you do X? ”), regardless of entitlement. Recipients, however, systematically modulated their preferences for particular forms as a function of a requester’s entitlement (Experiment 3). We also conducted exploratory analyses on the data from each experiment using human-normed judgments about entitlement and other social-interactional variables (e.g., degree of imposition); critically, for both Experiments 2 and 3, judgments about a requester’s entitlement explained variance in participants’ responses above and beyond other variables.
Variations in fatty acid composition and antioxidant content in olive fruits as a result of the application of phytoregulators to the olive tree (Olea europaea L.)

ABSTRACT A new procedure to minimize the degradation of fatty acids and polyphenols during the olive storage is here proposed. This procedure is based on pre-harvest treatments of Arbequina and Picual olive trees with methyl jasmonate and abscisic acid. As a result, total phenolic content increased in all treated Arbequina olives as compared with controls. In contrast to Arbequina, only abscisic acid resulted in total phenolic content increase in Picual olives. Regarding the antioxidant activity, neither of the phytoregulators was effective. Fatty acid composition was also affected by both of them in Arbequina and Picual. Saturated fatty acid decreased with both methyl jasmonate and abscisic acid whereas unsaturated fatty acids increased significantly in treated olives. Olives with higher antioxidant activity exhibited higher unsaturated/saturated fat ratio. The application of phytoregulators to olive tree can be interesting to the oil industry particularly when a delay in oil processing occurs and olives have to be stored.
Exploring the functional meaning of head shape disparity in aquatic snakes

Phenotypic diversity, or disparity, can be explained by simple genetic drift or, if functional constraints are strong, by selection for ecologically relevant phenotypes. We here studied phenotypic disparity in head shape in aquatic snakes. We investigated whether conflicting selective pressures related to different functions have driven shape diversity and explore whether similar phenotypes may give rise to the same functional output (i.e. many-to-one mapping of form to function). We focused on the head shape of aquatically foraging snakes as they fulfil several fitness-relevant functions and show a large amount of morphological variability. We used 3D surface scanning and 3D geometric-morphometrics to compare the head shape of 62 species in a phylogenetic context. We first tested whether diet specialization and size are drivers of head shape diversification. Next, we tested for many-to-one mapping by comparing the hydrodynamic efficiency of head shapes characteristic of the main axis of variation in the dataset. We 3D printed these shapes and measured the forces at play during a frontal strike. Our results show that diet and size explain only a small amount of shape variation. Shapes did not functionally converge as more specialized aquatic species evolved a more efficient head shape than others. The shape disparity observed could thus reflect a process of niche specialization under a stabilizing selective regime.
Myeloperoxidase gene expression in non‐infant pro‐B acute lymphoblastic leukaemia with or without ALL1/AF4 transcript

In this study, we examined myeloperoxidase (MPO) gene expression in a series of 31 non‐infant pro‐B acute lymphoblastic leukaemia (ALL) patients that included 16 cases with the t(4;11) translocation and/or the resultant ALL1/AF4 chimaeric gene. Sixteen out of 31 cases (51%) were MPO mRNA positive/enzyme negative. MPO mRNA was detected in nine out of 16 (56%) and seven out of 15 (47%) patients with and without the ALL1/AF4 fusion transcript respectively. The comparative study between MPO mRNA positive and negative cases showed statistically significant differences with regard to age and white blood cell (WBC) count, and was 39·5 years vs. 26·3 years (P = 0·016) and 71·4 × 109/l vs. 157·8 × 109/l (P = 0·046) in the MPO mRNA positive and negative groups respectively. The correlation analysis between MPO mRNA expression, age, WBC count and leukaemic relapse according to the presence/absence of the ALL1/AF4 fusion showed that the statistically significant differences observed in the whole group were related mostly to the ALL1/AF4‐positive ALL patients. In fact, in this latter group, the mean WBC count and patients' age were 85 ± 79 × 109/l vs. 289·8 ± 102 × 109/l (P = 0·0005) and 44·8 ± 15·3 years vs. 26·7 ± 13·7 years (P = 0·01) in patients with and without MPO mRNA expression respectively. It appears, therefore, that the assessment of MPO mRNA expression enables a further dissection of leukaemia heterogeneity in apparently homogeneous genetic/immunophenotypic ALL subsets.
The Benefits of Interoperability to Prevent Medication Error in Hospital

Background: Healthcare Information and Management Systems Society (HIMSS) describes interoperability as the extent to which systems and devices can exchange data, and interpret that shared data. Interoperability of health information systems can improve the accuracy of diagnosis, quality of care, and patient safety. One problem in patient safety is medication errors. Medication error defined as a failure in the treatment process that has the potential to lead to harm among patients. This study aimed to analyze the benefits of interoperability to prevent medication error in hospital. Subjects and Method: This was a systematic review study. The study were done by collecting related articles in English, published in 2014 to 2019. The databases used in this study were ProQuest, PubMed, and Sage Publication. The keywords used were interoperability, interoperable, electronic health records, data sharing, big data, health care information technology, hospitals, medication errors, medication without harm, unsafe medication, medication safety, prescribing errors, and prescription errors. Results: There were 10 articles that met the study criteria. From the articles it were found that interoperability prevents medication errors through (1) Providing quality information with credibility; (2) Preventing the occurrence of making recipes; (3) Increasing the effectiveness of information by direct transfer between systems; (4) Preventing data duplication, (5) Updating data in real time; (6) Data access in parallel by several users; (7) Prevention of data loss, differences in interpretation, and differences in measurement unit; (8) Reconciliation of treatment between patient and hospital; (9) Evaluation of diagnoses and services to patients remotely; and (10) Prevention of medication errors at the administrative stage. Conclusion: Interoperability increases accuracy of diagnoses, quality of care, patient safety, by increasing credibility of information. The existence of reconciliation between users, both doctors, nurses, pharmacists, service units, and patients, can prevent administrative errors and prescription making, and help doctors make decisions.
Numerical Study on Hysteretic Behaviour of Horizontal-Connection and Energy-Dissipation Structures Developed for Prefabricated Shear Walls

This study proposed a developed horizontal-connection and energy-dissipation structure (HES), which could be employed for horizontal connection of prefabricated shear wall structural system. The HES consists of an external replaceable energy dissipation (ED) zone mainly for energy dissipation and an internal stiffness lifting (SL) zone for enhancing the load-bearing capacity. By the predicted displacement threshold control device, the ED zone made in bolted low-yielding steel plates could firstly dissipate the energy and can be replaced after damage, the SL zone could delay the load-bearing and the load-displacement curves of the HES would exhibit “double-step” characteristics. Detailed finite element models are established and validated in software ABAQUS. parametric analysis including aspect ratio, the shape of the steel plate in the ED zone and the displacement threshold in the SL zone, is conducted. It is found that the HES depicts high energy dissipation ability and its bearing capacity could be obtained again after the yielding of the ED zone. The optimized X-shaped steel plate in the ED zone exhibit better performance. The “double-step” design of the HES is a potential way of improving the seismic and anti-collapsing performance of prefabricated shear wall structures against large and super-large earthquakes.
When is Disinformation (In)Credible? Experimental Findings on Message Characteristics and Individual Differences

ABSTRACT Disinformation on the Internet has become a major threat to our society. Especially false and inaccurate information in the form of news might have detrimental consequences for the democratic process when biasing individuals’ political views. To combat disinformation, a necessary first step is to investigate the factors relevant for individuals to detected false information online. Hence, we conducted an experiment (N = 294) to investigate effects of message factors and individual differences on individuals’ credibility and accuracy perceptions of disinformation as well as on their likelihood of sharing them. Results suggest that message factors, such as the source, inconsistencies, subjectivity, sensationalism, or manipulated images, seem less important for users’ evaluations of disinformation articles than individual differences. While need for cognition seems most relevant for accuracy perceptions, the opinion toward the news topic seems most crucial for whether people believe in the news and share it online.
Posterior reversible encephalopathy syndrome in preeclampsia

Background: Posterior reversible encephalopathy is a clinico-radiological syndrome marked by headache, altered mental status, seizures, visual disturbances, and extensive white-matter changes, also known as hyper perfusion encephalopathy, brain capillary leak syndrome, and hypertensive encephalopathy. This syndrome was a possible consequence of several medical conditions but especially in pregnancy it is associated with pre-eclampsia and eclampsia. Objective of this study was to know the incidence and analyze the clinical features, biochemical, and radiological abnormalities in posterior reversible encephalopathy syndrome (PRES) as a complication of preeclampsia. Methods: This was a one-year cross-sectional analytical study conducted at NRI general hospital, Chinakakani, Guntur of patients with the diagnosis of PRES. Data was obtained from medical records and analyzed them in terms of mean for continuous variables and percentages for categorical data. Results: Total no of patients diagnosed as PRES were 16 out of 127 patients of preeclampsia. Among them, 14 presented with eclampsia, and two presented with severe preeclampsia and imminent symptoms of eclampsia. Headache was the most common symptom (100%). PRES occurred at a peak SBP of ≥160 mmHg in 75% cases and peak DBP of ≥110 mmHg in 50% cases. Serum lactate dehydrogenase (LDH) level was ≥600 in 56.25% and serum uric acid level ≥6 in 50% of patients of PRES. The drug of choice was magnesium sulfate. Conclusions: Neuroimaging abnormality is a definitive component in the diagnosis of PRES. These cerebral abnormalities are vital components in the pathogenesis of eclampsia. Considerable number of patients of preeclampsia might develop PRES even without eclampsia, with mild elevation in BP, serum LDH, and serum uric acid levels.
Aseptic Loosening of Boneloc Cemented Exeter Total Hip Replacement. A 5 Year Follow-Up of the First 100 Hips

To evaluate the midterm performance of Boneloc cemented primary Exeter hip arthroplasty we examined the first 100 hips in 93 patients, who were alive at a median 56.6 (50–62) months after the operation. During the follow-up period 2 femoral stems and 2 acetabular cups were revised because of aseptic loosening from 3–5 years after the operation. A third acetabular cup was revised at the same time as a loose femoral stem, but was not found loose. The 5-year survival of both the stem and the cup was 98 per cent and for the surviving 98 hips the average Harris Hip Score was 87.6 (43–100) and the average pain score was 42.2 (10–44). Eighty nine per cent of patients were very satisfied or satisfied with their hip prosthesis and the patients’ own evaluations correlated well with the Harris Hip Scores. Follow-up radiographs revealed definite loosening of 3 stems and 2 cups, probably loosening of one stem and 2 cups, and possibly loosening of 2 stems and one cup. The Exeter stem subsided significantly within the cement mantle by median 3.3 (0–19) mm. In a subgroup of patients subsidence diminished significantly from the first 28 months compared to the last 31 months. Subsidence at the cement bone interface was only seen in 4 hips, where cement fractures had developed. Poor quality cementation, and valgus position of the femoral stem, significantly increased the risk of aseptic loosening, as did osteolysis and cement fracture. Poor cementing technique and continuous radiolucent lines at follow-up radiographs were positively correlated with acetabular cup loosening. The rather good midterm results with the Exeter femoral stem can probably be ascribed to the collarless, polished, double tapered stem design.
Association between Lymphovascular Invasion and Recurrence in Patients with pT1N+ or pT2–3N0 Gastric Cancer: a Multi-institutional Dataset Analysis

Purpose Patients with pathological stage T1N+ or T2–3N0 gastric cancer may experience disease recurrence following curative gastrectomy. However, the current Japanese Gastric Cancer Treatment Guidelines do not recommend postoperative adjuvant chemotherapy for such patients. This study aimed to identify the prognostic factors for patients with pT1N+ or pT2–3N0 gastric cancer using a multi-institutional dataset. Materials and Methods We retrospectively analyzed the data obtained from 401 patients with pT1N+ or pT2–3N0 gastric cancer who underwent curative gastrectomy at 9 institutions between 2010 and 2014. Results Of the 401 patients assessed, 24 (6.0%) experienced postoperative disease recurrence. Multivariate analysis revealed that age ≥70 years (hazard ratio [HR], 2.62; 95% confidence interval [CI], 1.09–7.23; P=0.030) and lymphatic and/or venous invasion (lymphovascular invasion (LVI): HR, 7.88; 95% CI, 1.66–140.9; P=0.005) were independent prognostic factors for poor recurrence-free survival. There was no significant association between LVI and the site of initial recurrence. Conclusions LVI is an indicator of poor prognosis in patients with pT1N+ or pT2–3N0 gastric cancer.
Histopathology of breast cancer patients in Tamilnadu: Tumor grading and staging through NPI

Breast carcinoma is the most common malignant tumor and the leading cause of cancer death in women. In India, recently it gains first spot in cancer incidence over uterus cancer. The objective of the present study was to acquire information about the extent and spread of breast carcinoma by grading and staging tumor on the available data. The present study included fifty consecutive masectomy specimens from Government Cancer Hospital, Tamilnadu. Out of 50 cases, 10 (20%) were grade 1, 35 (70%) were grade 2 and 5 (10%) were grade 3. Also 30 (60%) cases were T2, 10 (20%) cases were T3 and 10 (20%) cases were T4b. Out of 50, 45(90%) cases found to have regional lymphnode metastasis i.e. N1 and N2 grade. Out of 50, 35 (70%) were at Stage IIB, 5 (10%) were at Stage IIIA and 10 (20%) were at Stage IIIB. NPI scores were present in-between 3.4 - 5.4 in 25 out of 50 cases (50%). Majority of the cases were grade 2 tumors. Most cases were T2 or T3. Most of the cases with nodal metastases showed extra nodal spread. NPI scores in majority of the cases present in-between 3.4-5.4, indicating moderate prognosis. The present findings show extensive and advanced disease trends in cancer patients of Tamilnadu. A classificatio n system including histological grade and NPI could be more reliable in predicting breast cancer outcome.
Achieving Acceleration for Distributed Economic Dispatch in Smart Grids Over Directed Networks

In this paper, the economic dispatch problem (EDP) in smart grids is investigated over a directed network, which concentrates on allocating the generation power among the generators to satisfy the load demands with minimal total generation cost while complying with all constraints of local generation capacity. Each generator possesses its own local generation cost, and the total generation cost is the sum of all local generation costs. To deal with EDP, most of the existing methods, such as strategy based on push-sum, surmount the unbalancedness induced by the directed network via employing column-stochastic weights, which might be infeasible in distributed implementation. In contrast, in order to be suitable for the directed network with row-stochastic weights, we develop a novel directed distributed Lagrangian momentum algorithm, named as D-DLM, which integrates distributed gradient tracking method with two types of momentum terms and utilizes non-uniform step-sizes with respect to the updates of Lagrangian multipliers. If the largest step-size and the maximum momentum coefficient are positive and sufficiently small, D-DLM can linearly allocate the optimal dispatch on condition that the generation costs are smooth and strongly convex. Finally, a variety of studies on EDP in smart grids are simulated.
Response surface optimization and statistical analysis of composites made from calcium carbonate filler-added recycled polypropylene and rubberwood fiber

Mixture design method of experiments was used to determine the compositions of wood-plastic composite samples manufactured from recycled polypropylene (rPP), rubberwood flour (RWF), and calcium carbonate (CC). Factors were determined the mixture compositions rPP, RWF, CC, maleic anhydride-grafted polypropylene (MAPP), ultraviolet (UV) stabilizer, and lubricant (Lub) on properties of the samples, namely tension, compression, surface roughness, water absorption (WA), thickness swelling (TS), and thermogravimetric analysis (TGA). The specimens were produced by extrusion and compression molding methods. The analysis of variance and response surface methodology were employed for the analysis and optimization of the compositions. Optimal composition for overall response was 51.8 wt% rPP, 35.9 wt% RWF, 7.2 wt% CC, 3.9 wt% MAPP, 0.2 wt% UV stabilizer, and 1.0 wt% Lub with desirability score combining their output value of 0.757. The addition of CC content increased the mechanical properties but decreased the WA and TS. A high RWF content increased WA and TS with longer immersion times. The TGA of composites mainly depends on the chemical components of RWF and rPP types. The scanning electron microscope morphology in the composites with different amount of CC increased their densities due to good dispersion of CC as filler and good contact between the RWF reinforcement and rPP matrix.
A comparison of holistic, analytic, and part marking models in speaking assessment

This mixed methods study examined holistic, analytic, and part marking models (MMs) in terms of their measurement properties and impact on candidate CEFR classifications in a semi-direct online speaking test. Speaking performances of 240 candidates were first marked holistically and by part (phase 1). On the basis of phase 1 findings—which suggested stronger measurement properties for the part MM—phase 2 focused on a comparison of part and analytic MMs. Speaking performances of 400 candidates were rated analytically and by part during that phase. Raters provided open comments on their marking experiences. Results suggested a significant impact of MM; approximately 30% and 50% of candidates in phases 1 and 2 respectively were awarded different (adjacent) CEFR levels depending on the choice of MM used to assign scores. There was a trend of higher CEFR levels with the holistic MM and lower CEFR levels with the part MM. Although strong correlations were found between all pairings of MMs, further analyses revealed important differences. The part MM was shown to display superior measurement qualities particularly in allowing raters to make finer distinctions between different speaking ability levels. These findings have implications for the scoring validity of speaking tests.
