Published: October 2021

Abstract

Soil water content (SWC) plays a critical role in crop yield, irrigation scheduling, and water resources management. In the Canadian Prairies, the water content in the rootzone replenished by rainfall is rarely sufficient to satisfy crop water requirements. Thus, the need for robust and effective water management. Hydrologic modelling provides the opportunity to understand the underlying processes controlling and affecting soil water movement and distribution. Evapotranspiration (ET) is an important input of hydrologic models; thus, the estimation of ET could have significant consequences on modelling outcome and inference. The FAO Penman-Monteith (PM) is the recommended model for estimating the reference crop evapotranspiration (ETo). However, it is limited by requiring too many weather variables that are not readily available. Simple empirical ETo models have been developed as an alternative. In this study, six ETo models with different inputs were used to simulate soil water dynamics in a rainfed potato farm in Winkler, Manitoba, using the HYDRUS-1D model. The results showed that when used to simulate SWC, all the models followed a similar pattern, although a significant difference was observed at shallow depth (20 cm). Specifically, a significant difference (p < 0.05) was observed between observed and simulated SWC from Hargreaves Samani, Romanenko, Penman, and FAO-PM (missing) models. When used to simulate the crop evapotranspiration (ETc), there was no significant difference (p > 0.05) between observed and simulated ETc from FAO PM, Irmak, and Priestly – Taylor models. Hence, ETo models with fewer data inputs such as Irmak and Priestly – Taylor models can provide accurate and reliable results for water management in southern Manitoba.

Published: October 2021

Abstract
Background: This study aimed to map the available evidence related to physical activity (PA) and sedentary behaviour (SB) in Czech children and adolescents and suggest future directions and improvements to strengthen surveillance on PA and SB in the Czech Republic. Methods: The search of studies published between January 2000 to December 2020 included the Medline and Medvik databases and a hand search in eight Czech journals related to the topic. This review followed the "Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews".Results: Out of 350 identified studies, 79 met the selected criteria. The majority of studies were cross-sectional (89%), approximately two-thirds of the studies (61%) examined only PA, and half of the studies (51%) employed device-based assessments. Approximately 47% of studies reported the prevalence of physical inactivity based on inconsistently defined recommendations. Approximately, 14%, 23%, and 10% of studies focused on active transport, organized PA (including physical education or leisure-time PA), and parent-child PA, respectively. Conclusions: Future studies need to focus on longitudinal design and interventions, randomly selected samples, a mix of devised-based and self-reported methods, and recognition of health-related 24-h time-use patterns. This review advocates the governmental-supported development of a national surveillance system helping to the reduction of insufficient PA and excessive SB.

Abstract
Autoimmune diseases caused by pathogenic IgG4 subclass autoantibodies (IgG4-AID) include diseases like MuSK myasthenia gravis, pemphigus vulgaris or thrombotic thrombocytopenic purpura. Their etiology is still unknown. Polymorphisms in the human leukocyte antigen (HLA) gene locus, particularly in HLA-DRB1, are known genetic susceptibility factors for autoimmune diseases.
We hypothesized a similar role for HLA polymorphisms in IgG4-AID and conducted a systematic review and meta-analysis with case-control studies on IgG4-AID based on MOOSE and HuGENet guidelines.
Genotype (G) and allele (A) frequencies of HLA-DQB1*05 (G: OR 3.8; 95% CI 2.44-5.9; p < 0.00001; A: OR 2.54; 95% CI 1.82-3.55; p < 0.00001) and HLA-DRB1*14 (G: OR 4.31; 95% CI 2.82-6.59; p < 0.00001; A: OR 4.78; 95% CI 3.52-6.49; p < 0.00001) and the HLA-DRB1*14-DQB1*05 haplotype (OR 6.3; 95% CI 3.28-12.09; p < 0.00001 / OR 4.98; 95% CI 3.8-6.53; p < 0.00001) were increased while HLA-DRB1*13 (G: OR 0.48; 95% CI 0.34-0.68; p < 0.0001; A: OR 0.46; 95% CI 0.34-0.62; p < 0.00001) was decreased in IgG4-AID patients.
In conclusion, the HLA-DQB1*05 , HLA-DRB1*14 alleles and the HLA-DQB1*05-DRB1*14 haplotype could be genetic risk factors that predispose for the production of pathogenic IgG4 autoantibodies and the HLA-DRB1*13 allele may protect from IgG4 autoimmunity.
Effect of magnetic field, size and donor position on the absorption coefficients related a donor within the core/shell/shell quantum dot
Authors: AL Emre Bahadir 
Published: October 2021

Abstract
In this study, linear, nonlinear and total optical absorption coefficients related a single shallow donor atom confined in semiconductor core/shell/shell quantum dot heterostructure are researched in detail within the compact density matrix formalism approximation. For this purpose, firstly, the energies and the wavefunctions are computed by the diagonalization method in the effective mass approach. Moreover, the effects of size modulation, donor position and magnetic field are analyzed. The numerical results indicate that the linear and nonlinear parts of the absorption coefficients related with intersubband 1s-1p and 1p-1d donor transitions undergo significant changes.

Abstract
Background: The COVID-19 pandemic has contributed to unprecedented worries and challenges for pregnant women due to social restrictions and changes in maternity care provision. We aimed to investigate the mental health impact of COVID-19 pandemic on pregnant women in Sweden and explore factors associated with poor perinatal mental health in this specific context. Method: This was a nation-wide cross-sectional survey of pregnant women living in Sweden. Validated questionnaires were distributed through non-profit organizations´ websites and social media channels from May 2020 to February 2021. Perinatal depression, anxiety, and acute stress reaction were assessed using the Edinburgh Postnatal Depression Scale (EPDS), Generalized Anxiety Disorder-7(GAD-7) and Impact Event Scale (Revised)(IES-R), respectively. Sociodemographic characteristics and self-perceived mental well-being were also obtained. Factors associated with mental health outcomes were analyzed using multivariate logistic regression model. Results: Among a total of 522 participants, 42.5% (n=222) reported depression (EPDS ≥13), 25.3% (n=132) moderate to severe anxiety (GAD-7 score≥10), and 23.4% (n=122) moderate to severe acute stress reaction (IES-R ≥33). 27.4% participants (n=143, 27.4%) expressed concerns regarding their mental well-being during the pandemic. Pregnant mothers who had sick family members reported more severe poor mental health outcomes than those who did not (median [Interquartile range (IQR)] EPDS scores: 14.0 [8.75 – 18.0] vs 10.0 [6.0 – 14.0], p<.001; median [IQR] GAD7 scores: 7.0 [4.0 – 12.25] vs 5.0 [3.0 – 9.0], p<.001; median (IQR) IES-R scores: 20.0 [9.0 – 38.0] vs 15.0 [7.0 – 28.0], p=.008). Logistic regression analyses revealed that risk factors for poor mental health outcomes were having a sick family member with any illness, unemployment, giving birth, and experiencing an exceptional stressful life event. Having a higher educational level, younger age, and changing career during the pandemic were protective. Conclusion: Depression and anxiety were highly prevalent among pregnant women in Sweden during the COVID-19 pandemic, indicating a need for professional mental health support for this vulnerable group of population. Unemployment was an associated risk factor whereas younger age and higher educational level were protective suggesting an important role of socio-economic factors in modulating the impact of COVID-19 pandemic on perinatal mental health.

Abstract
Research on rare-earth hexaborides mainly focuses on tuning the electronic structure from insulating-to-metallic state and vice versa (referred as exotic phenomena) by high pressure experiments via displacive phase transformations, however, the structural evolution that contributing to this underlying failure mechanism remains not well understood. Herein, we examined the pressure induced structural evolution through a model system of europium hexaboride (EuB6). Transmission electron microscopy reveal that the nanoscale amorphous shear bands mediated by dislocations play a decisive role in deformation failure of EuB6 subjected to high pressure nanoidentation at room temperature. Density functional theory simulations confirm that these amorphous bands evolve by breaking B-B bonds within B6 octahedron of EuB6 during shear deformation. Our results underscore an important damage mechanism in hard and fragile hexaborides at high shear pressures.
A case of Pseudomyxoma Peritonei of an unexpected origin.
Authors: Csanyi-Bastien Marie , Blanchard France , Lamy Aude , Sabourin Jean-Christophe 
Published: October 2021

Abstract
Background:Pseudomyxoma peritonei (PMP) is a complex and partially understood disease defined by mucin deposits in the peritoneal cavity, mostly of appendiceal origin caused by the rupture of a mucocele often containing Low or High grade Appendiceal Mucinous Neoplasm (LAMN/HAMN). Other origins include primary ovarian mucinous cystadenoma or cystadenocarcinoma almost always with an associated teratoma, but to our knowledge no case of ovarian teratomatous appendiceal-like mucocele with LAMN has been reported as a cause of PMP.Case presentation:A 25-year old female with infertility was diagnosed with an isolated left ovarian tumor in a context of PMP. Histological examination revealed an ovarian teratoma containing an appendiceal-like structure with mucocele and LAMN, without any associated lesion of the appendix on full histological analysis. Molecular characterization of the ovarian lesion showed co-KRAS and GNAS mutations, as described in PMP of appendiceal origin, while only KRAS mutations are reported in primary ovarian mucinous tumor.Conclusions:Detection of co-KRAS and GNAS mutations in our case of ovarian teratomatous appendiceal-like mucocele with LAMN shows that when PMP derives from a mucinous ovarian lesion (with histological proof of none-appendiceal involvement), it is probably of a digestive teratomatous origin, emphasizing the need to actively search for tetatomatous signs in a context of ovarian PMP.

Abstract
Passive air sampling (PAS) was used to evaluate organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), polybrominated biphenyls (PBBs), hexabromocyclododecanes (HBCDDs), polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and per- and polyfluoroalkyl substances (PFASs) in the atmosphere of Medellin, Colombia. This was in accordance with a special initiative of the Global Monitoring Plan (GMP), which was implemented to provide information on new and emerging persistent organic pollutants (POPs).PAS was carried out for three months (four quartiles per year) over two consecutive years (2017 and 2018), and two punctual peaks of contamination in the monitored time were observed. The first peak was related to chlorinated compounds in the quartile 2017-Q3, in which the highest concentration of pentachlorobenzene (PeCB, 755.5 pg·m-3) was observed, and air concentration of PeCB in quartile 2018-Q4 (125.0 pg·m-3) was 3.7 times more than the initial concentration (33.7 pg·m-3). These results may be associated with waste incineration in or near the city. The second peak of contamination was associated with brominated compounds in the quartile 2018-Q1, which could be linked to recycling, incineration, and landfill deposit of these compounds. In this peak, the highest levels of PBDEs and HBCDD-isomers were observed (Σ10PBDEs, 107.2 pg·m-3 and Σ3HBCDDs-isomers, 289.0 pg·m-3). With regard to the concentrations of PBDEs, HBCDDs, PCDDs, and PCDFs, these showed a slight tendency to increase between 2017 and 2018. Finally, constants concentrations of pollutants such as DDT isomers and dieldrin were observed, although these compounds were banned in Colombia many years ago. In contrast, a slight decrease in some pollutants, such as aldrin, and α-endosulfan, was observed.Our study allowed the assessment of air levels of chlorinated, brominated, and fluorinated pollutants in Medellin, Colombia. These results provide an overall view of POPs levels and represent an initial attempt to identify local sources in order to monitor and surveillance the releases of these pollutants in the city and country.

Published: October 2021

Abstract
In order to probe the band gap engineering to tune optical properties in YAuPb1-xSix (x = 0, 0.25, 0.50, 0.75 and 1) alloys, we used all electron full-potential linearized augmented plane wave (FP-LAPW+lo) method within the frame work of the density functional theory. The optimized structural parameters were in good agreement with other theoretical and experimental results. The calculated results of elastic constant satisfy the condition for mechanical stability at each composition for cubic symmetry. In addition, the study of elastic parameters are summarized for the calculation bulk modulus, Young’s modulus, shear modulus, Kleinman parameters, Poisson’s ratio and Lame’s co-efficient. To predict the brittle (ductile) nature of this composition, the Cauchy pressure, Poisson’s ratio and B/G ratio were also calculated. Using modified Becke and Johnson GGA, the band gap values of each composition were computed precisely. Further, it was observed that for 0.25 < x < 0.75, band gap structure revealed a direct band gap configuration. In order to analyze the electronic structure of each composition, the total and partial densities of states have been investigated in detail. Furthermore, the investigation of optical parameters in terms of dielectric functions revealed the potential of these alloys for optoelectronic devices.

Published: October 2021

Abstract
Introduction. Dysregulation of vascular tone (VT) is one of the cardiovascular risk factors that significantly worsens the quality of life, and can be a predictor for persistent hypertension (HTN). The identification of preclinical stages of vascular pathology is the most promising for prevention of hypertension. Therefore, it is important to investigate the polymorphism of genes which end products are involved in the regulation of blood pressure (BP) and predispose to VT dysregulation.Objective. To investigate the clinical and prognostic significance of the AGT and AGTR1 polymorphic variants associated with increased cardiovascular risk in young and relatively healthy subjects and patients with HTN. Materials and methods. The study involved 90 young healthy subjects and 62 patients with hypertension. The exclusion criteria for young subjects were as follows: organic cardiovascular and central nervous system disorders and smoking. The exclusion criteria for patients with HTN were identical. Additionally, the patients with uncontrolled HTN were not included. The VT regulation was assessed by the active standing test in which the changes in blood pressure (BP) and heart rate (HR) were measured. The polymorphism was identified using DNA pyrosequencing.Results. The relationship between BP and HR and the AGTR1 A1666C A>C and AGT M268T T>C variants was established. Both in young subjects and hypertensive patients was found that the C allele of the AGTR1 A1666C A>C variant was associated with lower HR in supine compared with subjects without this allele. The risk allele C of the M268T T>C polymorphism was associated with lower sBP and dBP during the 1st minute of upright posture. The identified features can probably be explained by the vascular tone increased at baseline in the presence of these polymorphic variants which was manifested by smaller changes in BP and HR during the active standing test compared to subjects without these allelic variants. The C allele of the AGTR1 A1666C A>C variant was associated with earlier onset of HTN.Conclusion. The identification of the AGTR1 A1666C A>C and AGT M268T T>C variants can be informative for clarifying the risk of HTN when the young subjects are examined, as well as the probability of early onset of hypertension.

Published: October 2021

Abstract
Background Based on the cases collected in eight hospitals in Shanghai in recent three years, causes of medical disputes in Shanghai and influence factors of medical dispute levels were explored, and targeted suggestions were put forward. Methods Multistage sampling were used to collect 561 cases of medical disputes occurred in two Tertiary hospitals, two Secondary hospitals and four primary hospitals. The causes of medical disputes were analyzed by descriptive statistics and the factors affecting medical dispute were analyzed by means of one-way ANOVA and Logistic regression analysis. Results Factors of doctor and patient are involved in the causes of medical disputes, with 87.1% disputes related to doctors and 13.9% related to patients. The doctor’s factors include lack of communication (28.82%), low technical level (16.91%), lack of sense of responsibility (8.86%), defective case records (6.92%), imperfect operation (6.44%), inadequate experience (6.44%), inadequate condition evaluation (5.8%), irregular management process (4.03%), violation of diagnosis and treatment regulation (4.03%), misdiagnosis and mistreatment (3.54%), belated diagnosis and treatment (2.58%), postoperative complications (2.42%), equipment problems (1.13%), missed diagnosis (0.81%), poor condition monitoring (0.48%), unreasonable charge (0.48%) and poor service attitude (0.32%). The patient's factors include misunderstanding of medical behavior (43.48%), high expectation of prognosis (25%), bad attitude (13.04%), inadequate medical knowledge (7.61%), disturbance (6.52%), poor compliance (3.62%) and mistrust (1.09%). Among all medical disputes, there are 406 cases of level-4 medical disputes (78%), 95 cases of level-3 medical disputes (18%), 19 cases of level-2 medical disputes (4%), and no level-1 medical dispute. Meanwhile, the classification of diseases, treatment effect, doctors' violation of diagnosis and treatment regulation, and low technical level are the reasons for the level differences in medical disputes. Conclusions Factors of doctor in medical disputes in Shanghai mainly include inadequate communication and low technical level while the patient’s factors mainly contain misunderstanding of medical behavior and high expectation of the prognosis. Level-3 and 4 medical disputes take up the major part in all medical disputes. The classification of diseases, treatment effect, doctors' violation of diagnosis and treatment regulation, and doctor’s deficient technical level are high-risk factors requiring critical attention in medical disputes.
When Crop Producers Face Dynamic Climate Risks: Application of Multinomial Logit Model To Explain Adaptation Process
Authors: Bedeke Sisay Belay 
Published: October 2021

Abstract
Background: Climate change is one of the major environmental challenge particularly affecting crop producers who depend on climate sensitive rainfed system. The contextual nature of farmers’ adaptation and coping strategies to climate change continues to arouse the interest of several researchers. This study contributed to this growing area of research by examining factors and processes explaining the choice of crop producers’ adaptation to dynamic climate change risks. Method and material: Data were collected through household survey and interview. Multistage sampling was employed for selecting 340 household heads for interview. Descriptive statistics and multinomial logistic models were employed to analysis data collected. Result and discussion: Results indicate that despite perceived increase in current and future climate change risks, farmers are testing and implementing a range of strategies by adjusting sowing date, using late or early maturing varieties, diversifying crop production using legumes and migrating to nearby cities in search of additional jobs as an income source during dry seasons. Contexts-specific factors significantly influencing the choice of adaptation strategies include gender of the household, access to extension services, level of awareness and perceptions, timely access to climate and weather information and size of landholding per household. Conclusion: Based on the results of the study, it was concluded that the choice of adaptation to climate change is driven by much detailed socio-economic and institutional factors in addition to dynamic climatic factors. The study recommended that continuous financial, policy and technical support in terms of research, extension, innovation and awareness creation on improving behavioural and socio-economic aspects that influence adaptation choice should be provided.
