Aim To evaluate the incidence and features of left atrial appendage (LAA) thrombosis in patients with persistent atrial fibrillation (AF) after novel coronavirus infection (COVID-19).Material and methods Percutaneous echocardiography (pcEchoCG) was performed for 128 patients with persistent AF prepared for cardioversion, 36 (28.1 %) of whom had had COVID-19. In 3 (8.3 %) patients, the lung lesion area was 50–75 %; in 31 (86.1 %) patients, 25–50 %; in 1 (2.8 %) patient, less than 25 %. One patient had no lung lesion. Median time from the onset of COVID-19 to the patient enrollment in the study was 76.5 days. At the time of enrollment, the polymerase chain reaction test for SARS-CoV-2 was negative in all patients.Results Patients after COVID-19 and those who had not had COVID-19 were comparable by age (62.5±9.2 and 62.4±9.1 years, respectively; р=0.956), gender (men 52.8 and 59.8 %, respectively; р=0.471), and risk of stroke (score 2.19±1.28 and score 1.95±1.35, respectively; р=0.350). Duration of the last arrhythmia episode was longer for patients after COVID-19 than for the comparison group (76.5 and 45.0 days, respectively; р=0.011). All patients received oral anticoagulants. 55.6 % of COVID-19 patients received rivaroxaban, whereas 62.0% of patients who had not had COVID-19 were treated with apixaban. Median duration of the anticoagulant treatment was longer for COVID-19 patients than for the comparison group (61.5 and 32.0 days; р=0.051). LAA thrombus was detected in 7 (19.4 %) patients after COVID-19 and in 6 (6.5 %) patients of the comparison group (р=0.030). In COVID-19 patients, the thrombus adhered to LAA wall over the entire thrombus length whereas in patients who had not have COVID-19, the thrombus had a free part that formed a sharp angle with LAA walls. In the presence of LAA thrombus, the LAA blood flow velocity was considerably higher for COVID-19 patients than for the comparison group (31.0±8.9 and 18.8±4.9 cm/sec, respectively; p=0.010). At the follow-up examination performed at 24.0 days on the average, the thrombus was found to be dissolved in 80 and 50% of patients after and without COVID-19, respectively (р=0.343).Conclusion In patients with persistent AF after the novel coronavirus infection, LAA thrombosis was detected more frequently than in patients who had never had COVID-19; it was characterized by mural localization and was not associated with a decrease in LAA blood flow velocity.

Crusading in Livonia and Byzantine Romania Considered in a Comparative Review. Key Issues and Historiographical Notes
Authors: Ivanov Ivelin A. 
Published: April 2022

The article focuses on a topic that so far has not been studied in a comparative approach. The author addresses some basic problems of the comparative research, focusing on the general and the specific causes, the course, and the consequences of the crusading actions in the lands of Livonia and Estonia – in the northeast, and Romania – in the southeast. Reconsidering the already established models and theses in historical research on the Baltic campaigns, on the one hand, and the Third, the Fourth, and the Fifth Crusades, on the other, the author formulates some guidelines and approaches for a comparative study on crusading ‘on the edges’ in the late 12th – the early 13th centuries. The article analyzes several factors including the role of geographical and climatic conditions, the demographic expansion, the papal policy, the commercial maritime activity, and the role of the Knightly orders in the crusading campaigns under review. Furthermore, the author explores the political and social background of the crusading campaigns under question and the different models of interaction between the colonization stratum and the local population in Livonia and the Latin Empire in Constantinople.

Objectives. To investigate associations between COVID-19-related factors and depressive symptoms among primary care workers (PCWs) in São Paulo, Brazil, and to compare the prevalence of probable depression among PCWs before and during the pandemic. Methods. In a random sample of primary care clinics, we examined 6 pandemic-related factors among 828 PCWs. We used multivariate Poisson regression with robust variance to estimate prevalence ratios for probable depression. We assessed the prevalence of probable depression in PCWs before and during the pandemic in 2 comparable studies. Results. Adjusted prevalence ratios were substantial for insufficient personal protective equipment; experiences of discrimination, violence, or harassment; and lack of family support. Comparisons between PCWs before and during the pandemic showed that the prevalence of probable depression among physicians, nurses, and nursing assistants was higher during the pandemic and that the prevalence among community health workers was higher before the pandemic. Conclusions. Our findings indicate domains that may be crucial to mitigating depression among PCWs but that, with the exception of personal protective equipment, have not previously been examined in this population. It is crucial that governments and communities address discriminatory behaviors against PCWs, promote their well-being at work, and foster family support.

Abstract
Intercellular communication is important for tissue development and homeostasis, and when dysregulated contributes to a multitude of pathobiological processes. Cells communicate with each other by several mechanisms, including direct cell-cell contacts between membrane-tethered ligands and receptors on the cell surface, through secreted molecules that bind their cognate receptor on the receiving cell, or alternative modalities such as exosomes. The study of cell-cell communication networks using single-cell genomic approaches is now under intensive investigation, and innovative algorithms to interpret the data, infer how cells interact and identify the downstream effectors of a putative binding of a ligand to its cognate receptor are critically needed. Here, we describe a protocol to run CellComm, a data-driven systems biology algorithm that integrates single-cell RNA-sequencing, protein interaction networks, and gene regulatory networks to infer which cells within a heterogeneous tissue are actively communicating, as well as their downstream transcriptional programs. When spatial transcriptomics data is available, CellComm additionally identifies spatially-resolved cell-cell interactions within the tissue. This protocol is associated with our Nature Cell Biology paper describing our algorithm: CellComm infers cellular crosstalk that drives hematopoietic stem and progenitor cell development.

Abstract
Deploying advanced imaging solutions to robotic and autonomous systems by mimicking human vision requires simultaneous acquisition of multiple fields of views, named the peripheral and fovea regions. Low-resolution peripheral field provides coarse scene exploration to direct the eye to focus to a highly resolved fovea region for sharp imaging. Among 3D computer vision techniques, Light Detection and Ranging (LiDAR) is currently considered at the industrial level for robotic vision. LiDAR is an imaging technique that monitors pulses of light at optical frequencies to sense the space and to recover three-dimensional ranging information. Notwithstanding the efforts on LiDAR integration and optimization, commercially available devices have slow frame rate and low image resolution, notably limited by the performance of mechanical or slow solid-state deflection systems. Metasurfaces (MS) are versatile optical components that can distribute the optical power in desired regions of space. Here, we report on an advanced LiDAR technology that uses ultrafast low FoV deflectors cascaded with large area metasurfaces to achieve large FoV and simultaneous peripheral and central imaging zones. This technology achieves MHz frame rate for 2D imaging, and up to KHz for 3D imaging, with extremely large FoV (up to 150°deg. on both vertical and horizontal scanning axes). The use of this disruptive LiDAR technology with advanced learning algorithms offers perspectives to improve further the perception capabilities and decision-making process of autonomous vehicles and robotic systems.

Abstract
Background: Interventions to promote physical activity among women breast cancer survivors (BCS) in low to middle-income countries are limited. We assessed the acceptability and preliminary effectiveness of a theory-driven group dance intervention for BCS delivered in Bogotá, Colombia. Methods: We conducted a quasi-experimental study employing a mixed-methods approach to assess the 8-week, 3 times/week group dance intervention. The effect of the intervention on participants’ physical activity levels (measured by accelerometry), motivation to engage in physical activity, and quality of life were evaluated using Generalized Estimating Equations analysis. The qualitative method included semi-structured interviews thematically analyzed to evaluate program acceptability. Results: Sixty-four BCS were allocated to the intervention (N=31) or the control groups (N=33). In the intervention arm, 84% attended ≥60% of sessions. We found increases on average minutes of moderate-to-vigorous physical activity per day (intervention: +8.99 vs control: -3.7 min; p = 0.01), and in ratings of motivation (intervention change score= 0.45, vs. control change score= -0.05; p = 0.01). BCS reported improvements in perceived behavioral capabilities to be active, captured through the interviews. Conclusions: The high attendance, behavioral changes, and successful delivery indicate the potential effectiveness, feasibility, and scalability of the intervention for BCS in Colombia.Trial registration: Clinical trials NCT05252780, registered on Dec 7th, 2021 – Retrospectively registered Unique protocol ID: P20CA217199-9492018.

Published: April 2022

Abstract
A unique feature of leguminous plants is the establishment of nitrogen-fixing symbiotic bacterial genera in root or stem nodules which in recent times was re-evaluated for investigating the micro-flora discrete to nitrogen fixation. The research was carried out to isolate non-rhizobial endophytes (NRE) and Rhizobium from root nodules of Vigna radiata and ascertain their co-inoculation effect in pot and field conditions from Anand, Gujarat (India). 53 bacteria were isolated and based on phosphate solubilization, IAA production, and ARDRA profile, three potent isolates were selected and identified through partial 16S rRNA gene sequence analysis as Rhizobium sp. AAU B3 (GenBank® ACCN MH701891), Bacillus sp. AAU B6 (GenBank® ACCN MH701892) and Bacillus sp. AAU B12 (GenBank® ACCN MH701893). All strains showed nitrogen fixation ability, however, the highest nitrogen fixation 54.06 mg N g− 1 of glucose was demonstrated by the combination of all three strains. Furthermore, all three strains showed amplification of the nifH gene encoding Fe-protein of nitrogenase enzyme complex (~ 390 bp) and nodD gene was amplified by Rhizobium sp. AAU B3 (~ 980 bp). Maximum phosphate solubilization was recorded by combinations of all three strains demonstrated a higher solubilization index (SI) and available P in liquid. Likewise, all 3 strains in combination showed higher potash SI 2.98, the highest indole acetic acid production 165.50 µg ml− 1, and produced a significant amount of stress-relieving enzyme ACC deaminase. The succession of the root nodule formation within root hairs seedlings was observed under a fluorescence microscope after seed inoculation with 4′, 6-diamidino-2-phenylindole tagged NRE strains. The treatment receiving the combination of three bacterial inoculants recorded the highest plant growth, yield, and had a positive effect on the total bacterial count in pot and field study.

Abstract
Background. This study aim to provide an investigation of the relationship between a new metric of continuous glucose monitoring (CGM)-TIR (time in range) and serum uric acid (SUA) of patients with type2 diabetes mellitus(T2DM). Methods. 1056 individuals who was diagnosed with T2DM were enrolled in our study. They were classified into (Q 1≤19.56%), Q 2(19.56-62.66%), Q 3(62.66%-86.04%) and Q 4(>86.04%) groups by quartiles of the TIR. All patients underwent a 3-day continuous glucose monitoring (CGM). TIR a metric that denotes the time percent when their blood glucose is in the range of 3.9-10.0mmol/L during a 24-hour period. The correlation between TIR and Biochemical Measurements was analyzed using the Spearman analysis method. And the logistic regression was applied when analyzing the relationship between TIR and SUA by adjusting for the FBG、HbA1c(%), lipid situation. Results. Patients with ascending quartiles of TIR showed lower levels of TG, TC, FBG、HbA1c(<0.05) ,and increased levels of SUA(<0.001). the number of cases of the lowest quartiles of SUA (≤247.5 umol/L) decreased with the increment of TIR (P <0.05). TIR positively with SUA(p<0.001) and negatively with FBG, HbA1c, TC and TG (p<0.05). The Logistic regression found a significant association between TIR and SUA independent of FBG and HbA1c. Conclusion. Our research proved that TIR is associated with SUA independent of FBG and HBA1c in Chinese type 2 diabetes without hyperuricemia.

Published: April 2022

Abstract
BackgroundDuring the COVID-19 pandemic, shortage of nursing staff became even more evident. Nurses experienced great strain, putting them at risk to leave their jobs. Individual and organizational factors were known to be associated with nurses’ turnover intention before the pandemic. The knowledge of factors associated with turnover intention during the pandemic could help to foster nurses’ retention. Therefore, this review aims to identify factors associated with nurses’ turnover intention during the COVID-19 pandemic. MethodsAfter a systematic search of six databases, the resulting records were screened in a two-step process based on pre-defined inclusion and exclusion criteria. The included quantitative studies were synthesized qualitatively due to their methodological heterogeneity.Results A total of 19 articles were included in the analysis. Individual factors such as health factors or psychological symptoms and demographic characteristics were associated with nurses’ turnover intention. Organizational factors associated with turnover intention were e.g., caring for COVID-19 patients, low job control or high job demands, and moral distress. Resilience and supporting leadership could mitigate adverse associations with turnover intention.ConclusionsThe results help to identify high-risk groups according to individual factors and to develop possible interventions, such as trainings for nurses and their superiors, addressing individual and organizational factors. Future research should focus on longitudinal designs applying carefully defined concepts of turnover intention.

Abstract
This study aims to estimate the change points, tendencies, trends existing between the estimated change points of weather parameters and to explore relationships with forest cover loss, and CO2 emission in the Garo Hills region of Northeast India. The study is based on the secondary data of Precipitation, Maximum Temperature, Minimum Temperature, Relative Humidity, Tree cover loss, and CO2 emission at Garo Hills for the period 1984–2019. Mann Kendal’s and Sen’s slopes were used for estimating the trend of monthly and seasonal weather parameters and the breakpoints were estimated using Pettitt’s test. Further, we tried to establish a relationship between the variables under consideration using Pearson’s correlation and regression analysis. The results suggest that the precipitation was on a decreasing trend during most of the months and seasons. Maximum temperature depicted an upward significant shift, while minimum temperature demonstrated a downward shift in all seasons post-2008. The relative humidity was on an increasing trend post-1999 in all seasons except monsoon. Regression analysis reveals that the relative humidity and maximum temperature contributed negatively to precipitation. The forest cover loss and CO2 emission were positively correlated (r = + 0.58 and r = + 0.59) with the maximum temperature and negatively with the minimum temperature (r= -0.59 and r= -0.59). Results from this study will help the stakeholders to understand the temporal variability of weather factors and the effect of forest cover loss and CO2 emission on weather change in the region, and to formulate climatic mitigation strategies in the region.

Published: April 2022

Abstract
The work continues the theme of studying of the thunderstorm activity (TA) in the Far East of Russia. A comparison of the characteristics of TA in the south of the Russian Far East (including Sakhalin Island) was carried out according to the data of the World Wide Lightning Location Network (WWLLN) and observational data from 34 weather stations for the period 2009–2018. The estimates of the optimal radius of the region of the WWLLN data sampling in the weather stations vicinity are obtained by two statistical methods. Taking into account the previously published results, the average (median) values of the optimal radius in the south of the Far East of Russia amounted to 23(24) km. Differences in radius estimates for mainland, coastal, and island stations, as well as for night and daytime, are noted. The difference in the average annual TA according to the data of the weather stations and WWLLN varied within ±6 days/year and up to 1.3 days/year, the root mean square deviation were 2.4 days/year and 0.4 days/year, for the first and second methods, respectively. At the same time, the WWLLN data represent the main features of the intra-annual TA variation according to weather station data. It is shown that WWLLN data make it possible to distinguish individual thunderstorms in the course of TA at the diurnal scale, including those not noted in the observational data, and in the spatial distribution of lightning – mesoscale structures formed by thunderstorm rainfall clouds.
