Published: April 2022

Abstract
Background: Nursing students are one of the most vulnerable group suffering from workplace violence. This study aimed to investigate the violence toward Chinese nursing students, their response and effects on their careers. Methods: A cross-sectional study was conducted among 954 nursing students in ten universities in China. Results: The study found the incidence of workplace violence among nursing students was 42.98%. The violent incidents ranking from high to low were: verbal abuse, threat, body attack, sexual harassment and gathering disturbance. The majority of the nursing students chose to avoid the conflict during the incident. 86.34% of the students didn’t report the incidents. More than half of the victims developed post-traumatic stress disorder after the incidents. Students who explored violence scored lower in professional identity than those not. Measurement methods are used to build up the ability of the students to prevent, react, report and recover when they exposed to the incidents. Conclusions: Chinese nursing students were exposed to physical and psychological WPV during clinical practice with insufficient coping methods and psychological adjustment. The experience of violence significantly worsened the professional identity of nursing students.

Abstract
This paper discusses a new sensing technique for detecting ethanol concentration in aqueous solutions rapidly based on electromagnetic resonance. The sensor consists of two substrate layers and operates at 5G millimetre-wave frequencies (5G mm-wave). An experimental study of the new resonator's configuration is undertaken in determining the sensor's sensitivity. During the measurements, 6 samples were modelled with varying amounts of ethanol concentration in the water. The results showed that S11 resonance moves linearly towards higher frequencies as the ethanol content increases. The resonance shifted by 178 MHz for every 10% increase in ethanol. As a result, the proposed 5G mm-Wave sensing technique based on a replaceable sensing layer proves to be suitable for rapid, accurate, and low-cost alcohol content detection in liquids.

Abstract
Decreased albumin levels are common in chronic heart failure (HF), but little is known about its role in mortality risk in HF. This study developed a cohort prediction model based on 7,121 individuals with heart failure to evaluate the short-term mortality and prognostic role of albumin in patients with chronic HF. The cohort was from intensive care unit between 2001 to 2012 in a publicly available clinical database in intensive care called MIMIC III. We used a generalized additive model to determine the nonlinear correlation between serum uric acid and 14th - day, 28th - day and 90th day all-cause mortality in patients with heart failure. The results showed that serum albumin was an independent risk factor for 14th -,28th - and 90th day all-cause mortality, and had a linear relationship with all-cause mortality in Chronic systolic heart failure. There is an interaction between ARDS and the influence of albumin on the outcome. The all-cause mortality on the 90th day predicted better clinical results with the all-cause mortality on the 14th day.

Published: April 2022

Abstract
BACKGROUND: SMARCB-1-deficient sinonasal carcinoma(SDSC) is a rare type of paranasal sinus malignant tumor that was newly discovered in recent years. This type of tumor is characterized by a high degree of malignancy and rapid progression, and is mostly diagnosed at an advanced stage.CASE PRESENTATION: This report serves to describe a case of an atypical imaging appearance with clotting factor XI deficiency. Computed tomography and MRI revealed that uneven soft tissue density was in the right anterior ethmoid sinus with the right lamina papyracea bone defect. The tumour was surgically removed, followed by further radiotherapy and chemotherapy. No tumor recurrence and metastasis during six months follow-up. CONCLUSION: As shown in this case, the imaging presentation is not all typical for patients, especially in the early stages. We should connect clinical symptoms with imaging features and find key clinical features to facilitate early diagnosis.Whether XI coagulation factor deficiency is related to SMARCB-1 deficiency is still unclear.

Abstract
Microwave pyrolysis of corn stover has been optimized by Response surface methodology under different microwave power (500, 700, and 900 W) and three ratios of activated carbon additive (10, 15, and 20%) for obtaining maximum bio-oil yield followed by biochar. The optimal result has been evaluated and the environmental and techno-economic impacts of using solar-powered microwave heating have been tested. The optimal pyrolysis condition found to be 700 W microwave power and 10% of activated carbon. The yields of both bio-oil and biochar were about 74 wt.% under optimal condition. The higher heat values of 26 MJ/kg and 16 MJ/kg were respectively achieved for biochar and bio-oil. The major components of bio-oil were hydrocarbons (36%) and phenols (28%) with low oxygen-containing compounds (2%) and acids (2%). Using the solar-powered system, 20549 tonnes of CO2 can be mitigated over the lifetime of the set-up, resulting in USD 51373 in carbon credit earnings, compared to 16875 tonnes of CO2 mitigation and USD 42167 in carbon credit earnings from a grid electricity system. The payback periods for solar-powered and grid-connected electrical systems are estimated to be 1.6 and 0.5 years, respectively, based on biochar and bio-oil income of USD 39700 and USD 45400.

Published: April 2022

Abstract
Background
This study aimed to assess the relationship between vitamin D deficiency, cervical vertebral maturation (CVM) as an indicator of skeletal age, and dental age in adolescent patients.
Methods
In this cross-sectional study, the chronological age of 52 orthodontic patients aged between 10 and 14 years were recorded, and their serum level of vitamin D was determined using a radioimmunoassay test. The patients were then divided into three groups based on their serum vitamin D level: severe deficiency, moderate deficiency, and the control group with normal vitamin D. The panoramic radiographs of patients were assessed to determine their dental age using Demirjian’s method. CVM was determined on lateral cephalograms using Baccetti’s classification to specify the skeletal age. Data were analyzed using a t-test, linear regression, ordinal logistic regression and Pearson’s correlation coefficient (at P < 0.05, confidence interval = 95%).
Results
Skeletal age showed a significant difference between the group with severe vitamin D deficiency and the control group (P = 0.01); however, such difference was not observed between the group with moderate vitamin D deficiency and the control group (P = 0.12). Dental age was not significantly different between the groups with vitamin D deficiency and the control group (P = 0.26 for severe, and P = 0.39 for moderate deficiency).
Conclusions
Delayed skeletal maturation was observed in adolescents with severe vitamin D deficiency; However, dental development was not affected by this deficiency. Vitamin D status should be considered in decision-making for the initiation of growth modification orthodontic treatments.

Published: April 2022

Abstract
Ovarian cancer (OC), as a disease with difficult early diagnosis and treatment and poor prognosis, is a hot spot in global cancer research. Recent studies have revealed the metabolic reprogramming of tumor cells and the important regulatory role of long non-coding RNAs (lncRNAs) in tumor progression, which may expand new directions for the treatment of OC. In this study, OC data profiles were downloaded from The Cancer Genome Atlas (TCGA). Eight key fatty acid metabolism-related lncRNAs were finally screened for building a risk scoring model by univariate/ multifactor and least absolute shrinkage and selection operator (LASSO) Cox regression. To make this risk scoring model more applicable to clinical work, we established a nomogram containing the clinical characteristics of OC patients after confirming that the model has good reliability and validity and the ability to distinguish patient prognosis. To further explore how these key lncRNAs are involved in OC progression, we explored their relationship with LUAD immune signatures and tumor drug resistance. Finally, to elucidate the roles of these lncRNAs at the molecular level, functional enrichment analysis was also performed. The structure shows that the risk scoring model established based on these 8 fatty acid metabolism-related lncRNAs has good reliability and validity and can better predict the prognosis of patients with different risks of OC, and LINC00861in these key RNAs may be a hub gene that affects the progression of OC and closely related to the sensitivity of current OC chemotherapy drugs. In addition, combined with immune signature analysis, we found that patients in the high-risk group are in a state of immunosuppression, and Tfh cells may play an important role in it, which may become an important site for future OC immunotherapy. In conclusion, we innovatively established a prognostic prediction model with excellent reliability and validity from the perspective of OC fatty acid metabolism reprogramming and lncRNA regulation and found new molecular/cellular targets for future OC treatment.

Abstract
Neuroblastoma is the most common solid tumor in children. New treatment approaches are needed because of the harmful side effects and costs of the methods used in the treatment of neuroblastoma. Medicinal and aromatic plants are important for new treatment approaches due to their minimal side effects and economic advantages. Therefore, the present study was carried out to examine the cytotoxic effect of Chaerophyllum macropodum extract on human neuroblastoma (SH-SY5Y) and fibroblast (HDFa) cell lines. 3-[4,5-dimethylthiazole-2-yl]-2,5-diphenyltetrazolium bromide (MTT) and Lactate dehydrogenase release (LDH) assays were used to determine the cytotoxic effect of Chaerophyllum macropodum. The results revealed that Chaerophyllum macropodum had a significant cytotoxic effect on neuroblast cells at all concentrations used (p < 0.05). But it did not show any effect on human fibroblasts. As a result, the obtained data clearly showed that Chaerophyllum macropodum exerts a selective effect on neuroblastoma cells for the first time.

Abstract
Purpose: To assess the association between postnatal growth and neurodevelopment at the age of two years in extremely low gestational age newborns (ELGAN, <28 weeks’ gestation).Methods: Retrospective population-based cohort study including all live born ELGAN in 2006-2012 in Switzerland. Growth parameters (weight, length, head circumference, body mass index) were assessed at birth, at hospital discharge home, and two year follow-up (FU2). Unadjusted and adjusted regression models assessed associations between growth (birth to hospital discharge and birth to FU2) and neurodevelopment at FU2. Results: 1244 infants (mean GA 26.5±1.0 weeks, birth weight 853±189g) survived to hospital discharge and were included in the analyses. FU2 was documented for 1049 (84.3%) infants. The mean (±SD) mental and a psychomotor development index at 2FU were 88.9 (±18.0) and 86.9 (± 17.7), respectively. Moderate or severe neurodevelopmental impairment was documented in 23.2% of patients. Changes of z-scores between birth and discharge and between birth and FU2 for weight were -1.06 (±0.85) and -0.140 (±1.15), for length -1.36 (±1.34) and -0.40 (±1.33), for head circumference -0.61 (±1.04) and -0.76 (±1.32) as well as for BMI 0.22 (±3.36) and -0.006 (±1.45). Unadjusted and adjusted analyses showed that none of the four growth parameters was significantly associated with any of the three outcome parameters of neurodevelopment. This was consistent for both time intervals.Conclusion: In the present population-based cohort of ELGAN, neither growth between birth and hospital discharge nor between birth and FU2 were significantly associated with neurodevelopment at age of two years.
Is Coracoid Fracture With AC Dislocation An Unusual Case?
Authors: (MS MRCS) *Dr. Dheeraj Makkar 
Published: April 2022

Abstract
The coracoid process is the hook-shaped anterior process of the scapula, which runs cranially to the scapula and then to the anterolateral side. Its size, shape, and orientation vary from person to person. Coracoid fractures are rare. They can be missed on routine X-rays due to their anatomy. We present a rare case of fracture of the coracoid process and conservatively managed acromioclavicular joint dislocation. A 46-year-old day laborer presented to our emergency department with pain in his left shoulder and restricted movement following the traffic collision. The radiograph of the left shoulder demonstrated just AC joint dislocation. We ordered a CT scan of the shoulder based on the findings of the physical exam and a suspicious-looking X-ray. The CT scan revealed a minimally displaced coracoid fracture. Despite the concomitant dislocation, we managed the patient conservatively. After six weeks, the fracture had healed completely. The patient had a satisfactory outcome following rigorous physical therapy. Coracoid fractures are often overlooked due to their anatomical structure. We recommend specific shoulder x-ray views such as the scapula Y or axillary view to rule out a coracoid fracture. CT scan is considered to be the gold standard for diagnosis. Fractures can be treated conservatively or surgically, depending on the indication.
A life circle of the COVID-19 progression in a given region
Authors: Romanovski Mikhail 
Published: April 2022

Abstract
The Verhulst equation with variable parameters is applied to identify the features of disease spread within the framework of the general balance ‘expended-reached’ factors. The mathematical model of this balance facilitates revealing the growth features that cannot be identified by the SIR-like models. The proposed approach reconstructs actual object behaviour without any additional information on its features. Postulating the functional properties of the required values is not performed. The observations are processed under the condition that the reconstruction should ensure the small residual between the sample and the model-calculated state function.

Abstract
A Gram-stain-negative, anaerobic, non-motile, rod-shaped bacterium, designated as BGYT1T, was isolated from the feces of a cow in Andong, Republic of Korea. It was studied by using a polyphasic method to determine its taxonomic position. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BGYT1T formed a lineage within the genus Olsenella and was most closely related to O. umbonate KCTC 15140T (98.24%). The complete genome sequence of strain BGYT1T was 2,476,083 bp long with a G+C content of 66.9 mol%. The values for ANI (76.8%), AAI (67.26%), and dDDH (22.2%) compared to the closest related species were all below the threshold for bacterial species delineation. The strain was able to grow at pH 6.0-8.0 (optimum, pH 7.0), in the presence of 0.5-1.5% NaCl (optimum, 0.5%, w/v) and at the temperature range of 35-40°C (optimum, 35°C). The predominant fatty acids were C16:0 DMA (20.15%), C16:0 (20.15%), C18:0 (10.54%) and C18:1 cis 9 (16.99%). The polar lipid profiles contained phospholipid, glycolipid and five unidentified glycolipids. Based on its phenotypic analyses, phylogenetic and physiological characteristics, strain BGYT1T represented a novel species within the genus Olsenella, for which the name Olsenella intestinalis sp. nov. is proposed. The type strain is BGYT1T (=KCTC 25379T=GDMCC 1.3011T).

Published: April 2022

Abstract
Low-dimensional magnetism has long been the central issue in condensed matter physics, and van der Waals materials provide an ideal platform for exploring magnetism at the two-dimensional limit. The magnetic order in two-dimensional model materials is suppressed, and arguments based upon topology are useful for describing phases of matter. An example is the Berezinskii-Kosterlitz-Thouless transition where spin correlations over long distances eventually give rise to magnetic order; thus has never been realised experimentally in magnetic materials. A similar topological transition with vortices by chirality, handedness of the electronic spin arrangements, is possible without inducing any order; however, evidence for this higher-order vortex dissociation transition remains elusive. Here, we combine polarised neutron scattering and theoretical simulations to show that the transition occurs in a van der Waals magnet. We experimentally observe in-plane and out-of-plane spin moments, and their ratio, the spin-state anisotropy, shows a tendency for reversal across an anomalous temperature. Our simulations confirm the experimental findings; the tendency cannot be reproduced when removing the chiral vortices. The chirality-driven topological transition is general but has been challenging to be detected. Our results set a new paradigm for revealing topological characteristics with a higher-order degree of freedom.
Assessment of Ground Water Quality in Woreillu town, Ethiopia
Authors: Asfaw Melese Damtew 
Published: April 2022

Abstract
Water Quality Index of Woreillu town ground water was determined using Weight Arithmetic WQI method to assess the suitability of the ground water for drinking purposes as per WHO prescribed guidelines. The groundwater samples were collected from selected locations within one-year-monitoring period from January to August 2019. All the laboratory measurements of the physical, chemical and heavy metal parameters were measured using the standardized method. The WQI of the study ground water was established from ten physicochemical parameters (temperature, pH, Conductivity, Turbidity, Total alkalinity, TDS, TH, Nitrate, Phosphate, and Sulphate) and five heavy metals (Fe, Cu, Pb, Mn and Zn). The result showed that all physical and chemical parameters were almost below the maximum allowable level based on the WHO standards for drinking. On the other hand, the lead (Pb) was exceeded the maximum allowable limit in all the studied locations based on the WHO standards for drinking water. The computed WQI values range from 49 to 136. Therefore, out of 5 studied locations, one location was classified in the “Excellent water” class, one location as a “Good water” class, three as a “Poor water” class. Furthermore, lead, ph and turbidty were considered the most effective parameter on the determination of WQI in this study. The study revealed that only a few of the values for the heavy metals and physico-chemical parameters of the water samples were above the tolerable limits recommended by the WHO. This calls for regular monitoring and purification of boreholes to ensure good water quality.
Topological characterization for the geometric origin of transition in electrical conductivity for hybrid nanocomposites
Authors: Lee Jungmin , Lee Sang Hyun , Hwang Jinyoung 
Published: April 2022

Abstract
In this study, the analytical relationship between the electrical conductivity of hybrid nanocomposites consisting of conducting nanowires and insulating particulate fillers was investigated. We measured the performance as a function of the major factors defined by the combination of physical parameters of the constituent fillers. The major factors were identified using data mining techniques. The topological structure of the nanocomposites was described using a combination of Voronoi tessellation and the Swiss cheese model. Based on the geometrical framework, an analytical model of the electrical conductivity of the hybrid nanocomposites was built based on the Kozeny–Carman approach. The model delineates a one-dimensional characterization of the transition in electrical conductivity associated with the size ratio of the fillers and enables to visualize the quantitative relationship between the topological structure and electrical conductivity of the hybrid nanocomposites. Formalism facilitates the design of the physical properties of hybrid nanocomposites before their synthesis.
