COVID-19 and ICU admission associated predictive factors in Iranian patients.

Background The pandemic situation created an overwhelmed needs for ICU facilities, according to this problem, the need of accurate management of facilities represents boldness. In this study, prognostic risk factors for ICU admission among COVID-19 hospitalized patients were evaluated. Methods From 22 February to April 20, 2020. A total of 214 COVID-19 patients participated in this study. The included patients were between 18- 80 years old, and the patients who previously admitted for COVID-19 were excluded. The comorbid medical conditions, admission laboratory, demographic data, and first manifestations were analyzed between two groups, including ICU and non-ICU admitted patients. The statistical analysis, univariate and multivariate analysis were afforded. The value of the predictors in the risk assessment of ICU admission was estimated. Results 55(25.7%) patients were admitted in ICU. The ICU admitted patient's mortality rate was about 68%. The age was significantly higher among ICU admission group (P=0.03). Admission O2 saturation was significantly lower among ICU admitted patients (P=0.00). The kidney disease and malignancy history were more frequent in ICU-admitted patients (P=0.04, P=0.00). Myalgia was the clinical manifestation that significantly presented more frequent in ICU-admitted patients. INR, CRP, ESR, HB, and lymphocyte were significantly different between two groups. After multivariable analysis, admission O2 saturation, hematocrit, CRP and myalgia could significantly predict the risk of ICU admission. Furthermore, the value of predictors was estimated in our study. Conclusion Based on our results, the admission O2 saturation, HCT, CRP levels at first admission and myalgia presentation could be considered as the valuable predictors of ICU admission.

Translation, Adaptation and Validation of the Middle East Lower Limb Score (MELLS) into Arabic

Background: The Middle East Lower Limb Score (MELLS) is an adaptation of the WOMAC questionnaire, specifically adjusted according to the cultural issues of the middle eastern patients with Knee or hip disabilities. Objectives: The primary objective of this study was to verify if the translation and adaptation of the MELLS into Arabic could be used with ease and consistency by Arab-speaking patients suffering lower limb disabilities. Material & Methods: 110 participants were involved in this study. We performed the internal consistency tests with Cronbach’s alpha. We also calculated floor effects, ceiling effects, as well as test-retest reliability (intra-correlation coefficient). To estimate the validity of MELLS, we used two validated questionnaires – WOMAC and OHS. We confirmed the validity of MELLS questionnaire using Spearman’s correlation. Results: MELLS had a Cronbach’s alpha of 0.88 in the first assessment and 0.92 in the second assessment, which was very high and reliable. Both subscales of MELLS had an internal consistency higher than 0.85. No relevant ceiling and floor effect were observed among the responses. Furthermore, strong significant correlation with WOMAC subscales and OHS was observed, which suggested good construct validity. Responsiveness of MELLS, however, proved to be lower (but not considerably) than other two questionnaires. Conclusion: The Arabic Middle East Lower Limb Score (MELLS) is a useful and reliable diagnostic tool for Middle eastern patients with knee and hip problems.

The specific academic learning self-efficacy and the specific academic exam self-efficacy scales: construct and criterion validity revisited using Rasch models

Abstract Academic self-efficacy is mostly construed as specific; task-specific, course-specific or domain-specific. Previous research in the Danish university context has shown that the self-efficacy subscale in the Motivated Strategies for Leaning Questionnaire is not a single scale, but consists of two separate course- and activity-specific scales; the Specific Academic Learning Self-Efficacy Scale (SAL-SE) and the Specific Academic Exam Self-efficacy scale (SAE-SE). The SAL-SE and the SAE-SE subscales have previously been found to fit the Rasch model, have excellent reliability, and initial evidence of criterion validity has been established. The aim of this study was to conduct a new validity study of the SAL-SE and SAE-SE scales in the Danish university context. Specifically, whether the original findings of fit to the Rasch model, as well as the other psychometric properties of the scales could be replicated for a sample enrolled in another course context, as well as additional criterion validity. The sample consisted of 341 Psychology students enrolled in a first-semester statistics course. Results showed that the SAL-SE scale fit the Rasch model, while the SAE-SE scale did not as two items were locally dependent, reliability was excellent, and both SAL-SE and SAE-SE levels were positively related to final statistics grades.
The forensic exploitation of fingermark chemistry: A review

There is evidence that the use of fingerprints for the identification of an individual, either for civil or criminal purposes, has been considered in some form for over 2000 years (Barnes, 2011). The comparison of a mark left by an individual at a crime scene with sets of reference prints taken under controlled conditions is a cornerstone of forensic investigation, first being proposed in 1880 (Faulds, 1880). Following the generation of classification systems for fingermark patterns (Galton, 1892) and filing systems enabling databases to be searched (Henry, 1901), fingerprint comparison and identification has been successfully employed for over 120 years. The fact that fingerprint patterns are ‘unique’ (to the best of scientific knowledge) and persistent throughout life makes them a powerful identification tool. Indeed, the term ‘fingerprint’ is widely used across many other branches of science to describe something that is characteristic and easily distinguished from (e.g.) spectra of other nominally similar substances. In criminal investigations the focus is on locating marks that may have been left by the suspect at the crime scene. These can be of three principal types; a positive mark where material is transferred from the fingertip to the surface, a negative mark where the fingertip removes material (e.g. dust) from the surface, or a ‘plastic’ mark where the fingertip leaves a permanent impression in a soft substance such as putty. The classification of a positive mark can be further divided into a ‘patent’ mark where the material transferred is readily visible to the eye (e.g. mud, ink), or a ‘latent’ mark where the material transferred cannot typically be readily seen by eye and needs further enhancement to be seen. The chemistry of the material transferred from the finger to the surface is important to the visualisation of the contact trace. This is because chemical substances present can be utilised by a range of processes that either convert a latent mark into one that is visible or assist in further enhancing the pre-existing detail in a patent mark. The chemical development of fingermarks was observed as early as the 1860s (Quinche & Margot, 2010) and was already being explored in a more focused way in the 1920s (Mitchell, 1920), with a range of chemical processes targeting different constituents being proposed for use. This review will focus on the material that is ultimately transferred from the fingertip to the surface to form a fingermark. It will consider how this highly complex chemistry can be utilised by a wide range of chemical reagents, and by advanced analytical techniques in combination with imaging capabilities, to reveal the fingermark ridge detail and additional information contained within it.
Efficacy and toxicities of low-temperature plasma radiofrequency ablation for the treatment of laryngomalacia in neonates and infants: a prospective randomized controlled trial

Background Laryngomalacia is the most common cause of stridor in neonates and infants, and supraglottoplasty is the mainstay of surgical treatment. Although low-temperature plasma radiofrequency ablation (LTP-RFA) using coblation technology has been used for treating laryngomalacia, it is still lack of high-quality clinical evidence. Therefore, we conduct this prospective randomized study to clearly define the role of LTP-RFA for the treatment of laryngomalacia in neonates and infants. Methods Between Jan 2017 and Dec 2019, a total of 89 children with laryngomalacia were included for analysis. All patients were initially stratified according to the severity of laryngomalacia. Patients with severe laryngomalacia were randomly assigned to receive LTP-RFA or traditionally surgical supraglottoplasty, while patients with moderate laryngomalacia were assigned to LTP-RFA or observation. The primary end point was the efficacy and toxicities of LTP-RFA by assessing the changes of clinical score and visual analogue scale (VAS) symptom score. The total score was the combination of clinical score with VAS score. Results Of the 89 children, 40 children presented with severe laryngomalacia, and the remaining 49 children were diagnosed as moderate laryngomalacia. The median age was 68 days (range, 19 to 337 days). For children with severe laryngomalacia, our results showed that LTP-RFA treatment significantly reduced the operative time (5.55±1.66 vs. 18.7±5.31 min, P<0.001), length of hospital stay (6.71±1.15 vs. 7.95±1.55 days, P=0.008) and the amount of intraoperative hemorrhage (1.71±1.79 vs. 4.90±1.82, P<0.001) when compared to traditionally surgical supraglottoplasty, while the treatment efficacy was comparable between LTP-RFA and traditionally surgical supraglottoplasty in terms of changed total score (P=0.322), changed clinical score (P=0.135) and changed VAS symptom score (P=0.559). Additionally, for children with moderate laryngomalacia, LTP-RFA treatment significantly improved the symptom evaluated by total score (P<0.001), clinical score (P<0.001) and VAS symptom score (P<0.001) in comparison with the observation group. Post-operative pneumonia was observed in 10 patients. No surgical related death was reported. Conclusions The present study indicated that LTP-RFA was an effective treatment option for both severe and moderate laryngomalacia in neonates and infants with a low intraoperative complication. Long-term outcomes of LTP-RFA for laryngomalacia would be reported in further studies.
Parameterizations of Entrainment‐Mixing Mechanisms and Their Effects on Cloud Droplet Spectral Width Based on Numerical Simulations

Entrainment‐mixing mechanisms significantly affect cloud droplet number concentration, radius, and spectral shape. Quantitative examination of entrainment‐mixing effects on cloud droplet spectral width is lacking. This study examines the effects of entrainment‐mixing processes on cloud microphysics by 12,218 different setups, each simulated 10 times using the Explicit Mixing Parcel Model (EMPM) driven by the observational data from the Third Tibetan Plateau Atmospheric Scientific Experiment (TIPEX‐III) campaign. Parameterizations of entrainment‐mixing mechanisms are developed by relating homogeneous mixing degree to transition scale number that depends on the dissipation rate and droplet evaporation time scale. The correlation between relative dispersion of cloud droplet size distribution and homogeneous mixing degree changes from negative to positive with the decreasing homogeneous mixing degree. The different relationships are closely related to the competition between complete and partial droplet evaporation and the number concentration of small droplets, which are quantitatively described by two newly introduced dimensionless numbers. The competition is significantly affected by relative humidity and mixing fraction of entrained air as well as turbulence dissipation rate, but not much by cloud droplet number concentration. Especially, when relative humidity and dissipation rate are high, there is only a negative correlation. This study sheds new light on generalizing the homogeneous/inhomogeneous concept by considering relative dispersion and also provides parameterizations of entrainment‐mixing processes and relative dispersion for atmospheric models.
The mesoscale eddy field in the Lofoten Basin from high-resolution
Lagrangian simulations

Warm Atlantic-origin waters are modified in the Lofoten Basin in the Nordic Seas on their way toward the Arctic. An energetic eddy field redistributes these waters in the basin. Retained for extended periods, the warm waters result in large surface heat losses to the atmosphere and have an impact on fisheries and regional climate. Here, we describe the eddy field in the Lofoten Basin by analyzing Lagrangian simulations forced by a high-resolution numerical model. We obtain trajectories of particles seeded at three levels – near the surface, at 200 m and at 500 m depth – using 2D and 3D velocity fields. About 200 000 particle trajectories are analyzed from each level and each simulation. Using multivariate wavelet ridge analysis, we identify coherent cyclonic and anticyclonic vortices in the trajectories and describe their characteristics. We then compare the evolution of water properties inside cyclones and anticyclones as well as in the ambient flow outside vortices. As measured from Lagrangian particles, anticyclones have longer lifetimes than cyclones (16–24 d compared to 13–19 d), a larger radius (20–22 km compared to 17–19 km) and a more circular shape (ellipse linearity of 0.45–0.50 compared to 0.51–0.57). The angular frequencies for cyclones and anticyclones have similar magnitudes (absolute values of about 0.05f ). The anticyclones are characterized by warm temperature anomalies, whereas cyclones are colder than the background state. Along their path, water parcels in anticyclones cool at a rate of 0.02– 0.04 ◦Cd−1, while those in cyclones warm at a rate of 0.01– 0.02 ◦Cd−1. Water parcels experience a net downward motion in anticyclones and upward motion in cyclones, often found to be related to changes in temperature and density. The along-path changes in temperature, density and depth are smaller for particles in the ambient flow. An analysis of the net temperature and vorticity fluxes into the Lofoten Basin shows that while vortices contribute significantly to the heat and vorticity budgets, they only cover a small fraction of the domain area (about 6 %). The ambient flow, including filaments and other non-coherent variability undetected by the ridge analysis, hence plays a major role in closing the budgets of the basin.
Controlled formation of anatase and rutile TiO2 thin films by reactive magnetron sputtering

We discuss the formation of TiO2 thin films via DC reactive magnetron sputtering. The oxygen concentration during sputtering proved to be a crucial parameter with respect to the final film structure and properties. The initial deposition provided amorphous films that crystallise upon annealing to anatase or rutile, depending on the initial sputtering conditions. Substoichiometric films (TiOx<2), obtained by sputtering at relatively low oxygen concentration, formed rutile upon annealing in air, whereas stoichiometric films formed anatase. This route therefore presents a formation route for rutile films via lower (<500 °C) temperature pathways. The dynamics of the annealing process were followed by in situ ellipsometry, showing the optical properties transformation. The final crystal structures were identified by XRD. The anatase film obtained by this deposition method displayed high carriers mobility as measured by time-resolved microwave conductance. This also confirms the high photocatalytic activity of the anatase films.

The aim. Treatment of helminthiases of the digestive system remains an actual task of the medicine and pharma-cy worldwide. So, to meet the needs of the Ukrainian pharmaceutical market tablets based on albendazole and praziquantel were proposed. In order to establish the further production of the drug, studies were conducted on the development and validation of a method for the quantitative determination of one of the active substances – albendazole, in the presence of the second active substance praziquantel. Materials and methods. The object of the study was samples of tablets under the conditional name “AP-helmin”. Albendazole was extracted from tablets with ethyl alcohol when heated, 0.1 M sodium hydroxide solution was added and the obtained sample was evaluated spectrophotometrically in the ultraviolet light (308 nm). The method was conducted meeting the requirements of State Pharmacopoeia of Ukraine, harmonized with the relevant European Pharmacopoeia techniques. Results. The samples comply with the Bouguer-Lambert-Behr law in the concentration range 1×10 -3 – 1.2×10 -2 mg/ml, the correlation coefficient is ≥ 0.9998. The studied method of quantitative determination of albendazole in the drug meets the criteria of acceptability for the range of determination ±5.0 % by validation characteristics: specificity, linearity, precision, accuracy. The criterion of insignificance of the systematic error of the method is fulfilled – the systematic error of the method (0.24) is practically insignificant, that is, the method of analysis is characterized by sufficient correctness in the whole concentration range from 80 to 120 %. All the validation characteristics respond to the ac-ceptance criteria. Conclusions. A method for the quantitative determination of albendazole in tablets “AP-helmin” by spectrophotometry in ultraviolet light (308 nm) was worked out. It was experimentally confirmed that the second active pharmaceutical ingredient (praziquantel) had no affect the accuracy of the results obtained
Stability Indicating Liquid Chromatographic Method for the Simultaneous Determination of Rosuvastatin and Ezetimibe from Pharmaceuticals and Biological Samples

Fixed dose combinations of ezetimibe and rosuvastatin are well known to provide significantly superior efficacy to rosuvastatin alone in lowering total cholesterol, and triglyceride levels. Therefore, in this recent work, we prepared fixed dose (10mg/10mg) ezetimibe and rosuvastatin tablet formulations, and a simple, selective and we established and validated rapid chromatographic method for the sensitive and simultaneous determination of rosuvastatin and ezetimibe. We performed the separation on Zorbax SB-C18 (100 mm x 4.6 mm, 3.5 µm particle size) column at 30 oC with a mobile phase that has a composition as water containing 0.1% H3PO4:methanol:acetonitrile (50:25:25 v/v/v) at 1.2 mL/min flow rate. We further performed validation studies according to ICH guidelines. Furthermore, we exposed rosuvastatin and ezetimibe to degradation conditions. We plotted peak area vs. concentration graphs for rosuvastatin and ezetimibe and used for defining the linearity of the detector response. In this suggested method, we observed linear relationships varying from 0.05 to 50 µg/mL for ezetimibe concentrations and from 0.05 to 25 µg/mL for rosuvastatin concentrations. We found the limit of detection values for rosuvastatin and ezetimibe as 0.006 and 0.008 µg/mL, respectively. Moreover, we further used the established method for to the analysis of ezetimibe and rosuvastatin from real spiked samples of rabbit serum.
Combining ability analysis for yield and yield components in bread wheat

Combining ability analysis was studied in a twelve parents of bread wheat (Triticum aestivum L.). Which were crossed in a diallel fashion (without reciprocals) and their 66F1’s were grown in a field experiment at Wheat Research Unit, Dr. P.D. K.V. , Akola during in 2017-18 to study the combining ability for grain yield and its component traits. The gca and sca components of variances were significant for all studied characters. The (gca/sca) variances below unity in the generation showed the predominance of non-additive gene actions effects for all the traits. On the basis of general combining ability (gca) effect and per se performance, parents AKAW-5014 and AKAW-4924 emerged as good general combiners for grain yield per plant and average to high combiners for almost all the traits under study. Parent AKW-1071 was good general combiner for number of tiller/ plant and parents AKAW-5014 and AKAW-4924 also exhibited positive gca effects for days to 50% flowering, days to maturity, plant height, number of seed/earhead and grain yield. On the basis of sca effects, the crosses AKW-1071 xHPBW-01, AKAW-5017 x AKAW5014, AKAW-4924 x GW-322 and AKAW-5014 x WB-2 emerged as good specific cross combinations for grain yield per plot. Hybridization scheme for wheat improvement, such as multiple crossing or bi-parental mating could be useful in further manipulation of genes for economic purposes.
