Coagulopathy and Its Associated Factors Among Bleeding Diathesis Patients Attending at University of Gondar Specialized Referral Hospital, Northwest Ethiopia.

Background: Coagulopathy is the major cause of mortality and morbidity throughout the world. Globally, about 26 - 45% of healthy people have a history of bleeding symptoms, which may be a result of thrombocytopenia, factor deficiency, or pathological inhibitory.Objective: To assess coagulopathy and its associated factors among bleeding diathesis patients attending at University of Gondar Specialized Referral Hospital from January to May 2020.Method: A cross-sectional study was conducted on 384 study participants with bleeding diathesis recruited by using a convenient sampling technique. Socio-demographic and clinical characteristics were collected by using questioners. Then 6ml venous blood was collected with a needle and syringe method. About 3ml blood was transferred to EDTA test tube for platelet count and 2.7ml blood was transferred to a test tube containing 0.3ml of 3.2% sodium citrated anticoagulant for coagulation test. For those study participants with prolonged coagulation tests, a mixing test was done to differentiate the causes of coagulopathy whether factor deficiency or inhibitors. Blood film and stool examination were also done for malaria and intestinal parasite identification, respectively. The data were entered into EPI-Info version 3.5. 3 and then transferred to SPSS version-20 for analysis. Descriptive statistics were summarized as percentages, means, and standard deviations. Bivariate and multivariate logistic regression was used to identify the associated factors, and a P-value less than 0.05 was considered as statistically significant.Results: In this study, the prevalence of coagulopathy was 253/384 (65.9%; 95% CI: 61.16, 70.64). From them, 21.3% (54/253), 51.4% (130/253), and 27.3% (69/253) had only thrombocytopenia, only prolonged coagulation test, and mixed abnormality, respectively. Among participants with prolonged coagulation time, the prevalence of factor deficiency was 21.1% (42/199). Cardiac disease (AOR = 4.80; 95% CI: 2.65, 23.1), and other chronic diseases (AOR = 8.1; 95% CI: 1.84, 35.58) were significantly associated with coagulopathy.Conclusion: Coagulopathy due to inhibitory was a public health problem. The participant with cardiac and other chronic disease was associated with coagulopathy. Therefore, mixing tests could done for all prolonged coagulation test and it could be considered as a routine laboratory test.
Comparing the potentials of clay and biochar in improving water retention and mechanical resilience of sandy soil

Abstract Changing climate is threatening rainfall regularity particularly in the semi-arid and arid regions; therefore, strategies to conserve water within their coarse-grained soils and to improve water use efficiency of crops are critical. This study compared the effectiveness of biochar and two types of clay materials in augmenting water retention and improving mechanical resilience of fine sand. The amendment of fine sand with woodchip-biochar and kaolinite (non-swelling clay) and Na-bentonite (swelling clay) improved the water retention capacity and interparticle bonding of the substrate depending of the rate of amendment and water content of the substrates. Na-bentonite was more effective at increasing water retention capacity at more negative matric potentials. Biochar was more effective at saturation due to the increased porosity, while kaolinite responds similarly to biochar. It is, however, shown that most of the water retained by the Na-betonite may not be available to plants, particularly at high amendment rate. Furthermore, the clay and biochar materials improved particle bonding in the fine sand with the Na-bentonite being more effective than biochar and kaolinite (in that order) in strengthening interparticle bonds and improving the resilience of fine sand, if the rate of amendment is kept at ≤50 g kg-1.

Metabolic and Cardiovascular Effects of Body Weight Support Treadmill Walking in Healthy Adults

PURPOSE: The use of body weight support treadmill (BWST) training for rehabilitation of patients with brain injuries, as well as musculoskeletal and neuromuscular impairments, is an emerging clinical treatment method. Because of the limited evidence of physiological stress of BWST training, the purpose of this study was to describe the metabolic and cardiovascular response to varying levels of BWST walking in healthy adult subjects. METHODS: A total of 21 subjects (10 females; 34+6.7 yr; 74.6+14.3 kg; 170.8+6.9 cm; 26.1+5.3 kg/m) provided their informed consent to participate in three 5-minute walking trials at a self-selected treadmill speed, with body weight support (BWS) of 0, 15, and 30%. Test order was randomized for each subject. Subjects rested for a minimum of 5 minutes between each trial, and did not begin a subsequent trial until HR was verified to be < 5 bpm of HR rest. Mean HR (12-lead ECG), BP (auscultation), oxygen uptake (continuous indirect calorimetry), and RPE (Borg ratio scale) were determined from the last 3 minutes of each trial. Mean values for all variables were assessed for difference between trials using repeated measures analysis of variance (SPSS ver. 24, New York, NY). RESULTS: At rest, HR was 78.2+11.5 bp and BP was 121.2+7.9 / 76.9+8.0 mmHg. Mean walking speed of subjects was 64.2 m/min. HR and systolic BP significantly (p<0.05) increased from rest to exercise at all BWS levels, with no significant difference in diastolic BP seen from rest to exercise at all BWS levels. There was no statistical difference among levels of BWS for HR, BP, RPE, oxygen uptake, respiratory exchange ratio, respiratory rate, tidal volume, and METs. CONCLUSIONS: Metabolic and cardiovascular responses to treadmill walking at 3 levels of BWS (0, 15, 30%) were similar in apparently healthy adult subjects.
Short term results following hip arthroplasty (total/hemi) in elderly patients with femoral neck fracture in a tertiary care hospital

Background: Intracapsular fractures of the neck of femur are a major cause of morbidity and mortality in elderly population in India. The primary goal of treatment in these patients is to get the patients to the preinjury level of functionality as early as possible and with minimal complications. Multiple modes of operative treatment in the form of fixation devices (screws, plates, nails) and replacement (hemi or total replacement) are available for this fracture. However, a high rate of complications and revision surgeries has been found after internal fixation in this population group owing to the unique challenges to fixation in the form of co morbidities and osteoporosis among others. Instead of internal fixation, replacement is thus a viable option. Materials and Methods: 100 patients (age >65 years) with a femoral neck fracture were treated over a two-year period (May 2018 to April 2020) with some form of hip replacement after appropriate anesthetic fitness. Results: We had good results in majority of the patients in terms of return to pre-fracture level of functionality, independent ambulation and satisfaction with the results. A majority of patients treated with hemiarthroplasty recovered without incidence while all patients of total hip replacement progressed without incidence. There were 10 cases of suture line infection which recovered satisfactorily with a change of antibiotics, 4 cases of deep infection for which debridement and implant removal was required, 3 cases of deep vein thrombosis and 7 cases of dislocation. Conclusion: Hip replacement is a viable option for treatment of femoral neck fractures in patients more than 65 years of age. Return to preinjury level of functionality is pretty satisfying and early if the patient is actively mobilized as early as possible postoperatively. There are no risks of nonunion, malunion and implant related complications as compared to internal fixation devices.
Estudo Hidrodinâmico de um relé de gás utilizando a fluidodinâmica computacional (CFD).

O presente trabalho teve como objetivo fornecer um estudo hidrodinâmico de um rele de gas a partir da ferramenta fluidodinâmica computacional, para prever perfis de velocidade, variacao de temperatura e pressao do oleo ocasionados por grandes falhas eletricas no interior do transformador (curtocircuito), partir das propriedades fisicas, coeficiente de expansao volumetrica e condicoes operacionais. Obtendo informacoes mais precisas a respeito do comportamento do oleo no sistema. A metodologia proposta foi baseada em tres etapas: pre-processamento (desenvolvimento da malha computacional, a partir da geometria tridimensional real), processamento (definicao das condicoes de contorno, escolha e resolucao modelos hidrodinâmicos em ambiente de simulacao FlowSimulation) e pos-processamento (obtencao dos perfis de velocidade, inclinacao da aleta, variacao da temperatura e pressao). Os resultados mostraram que no escoamento ascendente, a aleta ira se deslocar quando a velocidade do fluido superar 0,04 m/s. Verificou-se tambem, que elevacoes significativas de temperatura (>60oC), podem estar associadas a falhasgraves, levando a combustao do oleo isolante, acarretando velocidades maiores ou iguais a 2 m/s, resultando na inclinacao maxima da aleta (36,5o). Em relacao ao escoamento descendente, observou-se uma pequena perda de carga no sistema, equivalente a 2,84 kPa, provocado pela reducao na temperatura do oleo.
Autism Awareness Scale for Security Officers Working in Hospitals: A Study of Validity and Reliability

Objective: The purpose of this study was to evaluate the knowledge and awareness toward autism among security officers working in hospitals and to explore the validity and reliability of the Autism Awareness Scale for Security Officers (AASSO) developed by the researchers. Methods: This methodological study was conducted at two Government Training and Research Hospitals in Istanbul, Turkey. A total of 135 security officers were included in the study and the data were obtained between February and April 2019. The AASSO is a 4-point Likert type scale and consists of 20 items. The factor structure of the scale was extracted by performing exploratory factor analysis. Results: Most of the participants were males (n=79; 58.5%) and high school graduates (n=86; 67.7%). Participants considered autism mostly as “a kind of mental retardation” (n=69; 51.9%), followed by “social interaction problem” (n=24; 18.0%). The AASSO reduces autism awareness into 3 factors (‘Coming across’, ‘Communication’ and ‘Interaction with the environment’), with eigenvalues ranging from 9.417 to 1.201 and explained 65.45% of all variance. Cronbach’s alpha values for the AASSO was 0.936 and ranging from 0.921 to 0.809 for the subscales. Conclusion: According to these results AASSO is a valid and reliable scale. The consequence of further studies especially conducted on non-healthcare professionals of hospitals should be establishing Autism-friendly Hospitals.
Establishing a New Role for Antidumping Policy: Protection of an Unestablished Industry (Morocco–Hot-Rolled Steel (Turkey))

Abstract This article analyses economic and legal issues in the WTO dispute between Morocco and Turkey over hot-rolled steel. Over 2013–2014, the Moroccan government conducted an antidumping investigation against two Turkish steel producers. Morocco's investigation concluded that Turkish dumping was retarding the establishment of a new domestic industry; antidumping duties were imposed against both Turkish producers. Turkey filed a complaint at the WTO in 2016, asserting procedural and substantive violations. The Panel found that Morocco had acted inconsistently with a number of WTO obligations, including those regarding its injury investigation. Although Morocco initially appealed the Panel's decision, it withdrew its appeal after the antidumping duties expired in September 2019. This case is unusual and important in that it was the first antidumping case in which a country sought to use antidumping duties to protect a newly developing industry. The Panel may have missed an opportunity to explore the definition of an ‘unestablished’ industry for purposes of determining injury in an antidumping investigation.
Diffusional Response of Layer-by-Layer Assembled Polyelectrolyte Chains to Salt Annealing

We report on the effect of salt on diffusion of polyelectrolyte (PE) chains within electrostatically assembled polyelectrolyte multilayers. Layer-by-layer (LbL) films were assembled using poly(methacrylic acid) (PMAA) as a polyanion and quaternized poly(2-(dimethylamino)ethyl methacrylate) as a polycation. Fluorescence recovery after photobleaching and neutron reflectometry were used to monitor the center-of-mass diffusion of PMAA chains in directions parallel and perpendicular to the substrate (D∥ and D⊥, respectively). Film intermixing and polymer chain diffusion in the direction perpendicular to the substrate exhibit an unusual dependence on the PMAA molecular weight, with dramatically stronger diffusional response to salt annealing for the films formed by PMAA with the lowest molecular weight of 7 kDa. Films assembled with this lowest molecular weight PMAA reveal that both diffusion coefficients of PMAA chains (D∥ and D⊥) depend exponentially on the concentration of salt in the annealing solutions, wi.

Hamiltonian claw-free graphs involving induced cycles

The hamiltonian problem is an important topic in structural graph theory, which is closely related to Four Color Problem. Hence lots of graph scholars are dedicated to this topic. There are many authors working for finding some sufficient conditions for hamiltonian property of graphs. Let G be a claw-free graph with n vertices and δ(G)≥3. In this paper, we show that if G has an induced cycle of length more than (4n – 2δ(G)–4)(δ(G)+2)−1, then G is hamiltonian. The result is best possible if δG is 3 or 4.
LncRNA PCED1B-AS1 is Overexpressed in Hepatocellular Carcinoma and Regulates miR-10a/BCL6 axis to Promote Cell Proliferation

Background: PCED1B-AS1 has been characterized as an oncogene in glioma, while its role in hepatocellular carcinoma (HCC) is unknown. This study was performed to analyze the involvement of PCED1B-AS1.Methods: Expression of PCED1B-AS1 in paired HCC and non-tumor tissues from 62 HCC patients was determined by RT-qPCR. The correlation between PCED1B-AS1 and miR-10a or BCL6 was analyzed by linear regression. The 62 HCC patients were followed up for 5 years to analyze the prognostic value of PCED1B-AS1 for HCC. The interactions among PCED1B-AS1, miR-10a and BCL6 were analyzed by overexpression experiments. Cell proliferation was analyzed by CCK-8 assay.Results: PCED1B-AS1 was upregulated in HCC and predicted poor survival. Across HCC tissues, PCED1B-AS1 was inversely correlated with miR-10a, and positively correlated with BCL6 mRNA. In HCC cells, PCED1B-AS1 overexpression mediated the downregulation of miR-10a and upregulation of BCL6. Moreover, PCED1B-AS1 overexpression reduced the inhibitory effects of miR-10a overexpression on BCL6 expression and cell proliferation. Conclusions: PCED1B-AS1 is overexpressed in HCC and regulates miR-10a/BCL6 axis to promote cell proliferation.
Seeing is Believing: Annual Report 'Graphicity' and Stock Returns Predictability

Using a large hand-collected dataset, we provide novel evidence on the additional information embedded in the designs and graphs of financial reports. We find that firms that add graphic financial reports experience a positive 2.7% abnormal returns in the following 3 to 6 months. The finding remains after controlling for financial market constraints, investor sophistication, and information asymmetry. We also develop a theoretical model to explain the result. Further analysis reveals that firms with lower accruals, larger size, and higher Fog index tend to add graphic information, and they are likely to increase their corporate investments in the following year.
Phylogeny and Structure of Fatty Acid Photodecarboxylases and Glucose-Methanol-Choline Oxidoreductases

Glucose-methanol-choline (GMC) oxidoreductases are a large and diverse family of flavin-binding enzymes found in all kingdoms of life. Recently, a new related family of proteins has been discovered in algae named fatty acid photodecarboxylases (FAPs). These enzymes use the energy of light to convert fatty acids to the corresponding Cn-1 alkanes or alkenes, and hold great potential for biotechnological application. In this work, we aimed at uncovering the natural diversity of FAPs and their relations with other GMC oxidoreductases. We reviewed the available GMC structures, assembled a large dataset of GMC sequences, and found that one active site amino acid, a histidine, is extremely well conserved among the GMC proteins but not among FAPs, where it is replaced with alanine. Using this criterion, we found several new potential FAP genes, both in genomic and metagenomic databases, and showed that related bacterial, archaeal and fungal genes are unlikely to be FAPs. We also identified several uncharacterized clusters of GMC-like proteins as well as subfamilies of proteins that lack the conserved histidine but are not FAPs. Finally, the analysis of the collected dataset of potential photodecarboxylase sequences revealed the key active site residues that are strictly conserved, whereas other residues in the vicinity of the flavin adenine dinucleotide (FAD) cofactor and in the fatty acid-binding pocket are more variable. The identified variants may have different FAP activity and selectivity and consequently may prove useful for new biotechnological applications, thereby fostering the transition from a fossil carbon-based economy to a bio-economy by enabling the sustainable production of hydrocarbon fuels.
