Published: February 2022

В данном исследовании представлены клинико-лабораторные данные 19 пациентов с онкогематологическими заболеваниями и инфекцией COVID-19. В результате анализа показателей пациентов проспективной группы установлено, что инфекция COVID-19 наиболее часто выявлялась у пациентов с острым лимфобластным лейкозом - 7 (36,8%) и острым миелобластным лейкозом - 7 (36,8%) из 19 пациентов. У 7 (36,8%) пациентов инфекция протекала в бессимптомной форме, 8 (42,1%) - в легкой, 1 - средней тяжести и 3 - тяжелой. Большинство коагуляционных показателей у пациентов с гемобластозами не отличались от значений соответствующих показателей у детей в контроле. Статистически значимо превышали контроль показатели активности и содержания фактора Виллебранда, VIII фактора, Д-димеров, а также естественных антикоагулянтов. Описанные изменения у большинства пациентов сохранялись на протяжении как минимум 180 дней после начала заболевания. Профилактику низкомолекулярным гепарином (НМГ) проводили 1 пациенту с тяжелой формой инфекции COVID-19. Ни в одном случае не было зарегистрировано тромбозов у пациентов, перенесших COVID-19.
This study presents and analyzes the clinical and laboratory data of 19 patients with oncohematological pathology and COVID-19 infection. As a result of the analysis of the prospective group, it was found that COVID-19 infection is most often associated with acute lymphoblastic leukemia - 36.8% and acute myeloid leukemia - 36.8% patients. In 7 (36.8%) cases the infection was asymptomatic, in a mild form - 8 (42.1%) cases. Most of the coagulation parameters in those with hemoblastosis did not differ from the values of the corresponding parameters in control children. There were statistically significant differences in the indices of von Willebrand factor, VIII faсtor, D-dimers, and natural anticoagulants. The described changes in most patients persisted for at least 180 days after the disease. Low molecular weight heparin prophylaxis was given to one patient with severe COVID-19 infection. However, we did not notice an increase in thrombosis in patients who underwent COVID-19.

Published: February 2022

Abstract
We report on an experimental investigation of the jitter of electrons from laser wakefield acceleration. The relative arrival timings of the generated electron bunches were detected via electro-optic spatial decoding on the coherent transition radiation emitted when the electrons pass through a 100 μm thick stainless steel foil. The standard deviation of electron timing was measured to be 7 fs at a position outside the plasma. Preliminary analysis suggested that the electron bunches might have durations of a few tens of femtoseconds. This research demonstrated the potential of laser wakefield acceleration for femtosecond pump–probe studies.
Amplitude Matching for Multizone Sound Field Control
Authors: Abe Takumi , Koyama Shoichi , Ueno Natsuki , Saruwatari Hiroshi 
Published: February 2022

<p>A multizone sound field control method, called amplitude matching, is proposed. The objective of amplitude matching is to synthesize a desired amplitude (or magnitude) distribution over a target region with multiple loudspeakers, whereas the phase distribution is arbitrary. Most of the current multizone sound field control methods are intended to synthesize a specific sound field including phase or to control acoustic potential energy inside the target region. In amplitude matching, a specific desired amplitude distribution can be set, ignoring sound propagation directions. Although the optimization problem of amplitude matching does not have a closed-form solution, our proposed algorithm based on the alternating direction method of multipliers (ADMM) allows us to accurately and efficiently synthesize the desired amplitude distribution. We also introduce the differential-norm penalty for a time-domain filter design with a small filter length. The experimental results indicated that the proposed method outperforms current multizone sound field control methods in terms of accuracy of the synthesized amplitude distribution. </p>
Spatial frequency equalization does not prevent spatial–numerical associations
Authors: Adriano Andrea , Rinaldi Luca , Girelli Luisa 
Published: February 2022

AbstractThere is an intense debate surrounding the origin of spatial–numerical associations (SNAs), according to which small numbers are mapped onto the left side of the space and large numbers onto the right. Despite evidence suggesting that SNAs would emerge as an innate predisposition to map numerical information onto a left-to-right spatially oriented mental representation, alternative accounts have challenged these proposals, maintaining that such a mapping would be the result of a mere spatial frequency (SF) coding of any visual image. That is, any smaller or larger array of objects would naturally contain more low or high SF information and, accordingly, each hemisphere would be preferentially tuned only for one SF range (e.g., right hemisphere tuned for low SF and left hemisphere tuned for high SF). This would determine the typical SNA (e.g., faster RTs for small numerical arrays with the left hand and for large numerical arrays with the right hand). To directly probe the role of SF coding in SNAs, we tested participants in a typical dot-arrays comparison task with two numerical sets: one in which SFs were confounded with numerosity (Experiment 1) and one in which the full SF power spectrum was equalized across all stimuli, keeping this cue uninformative about numerosity (Experiment 2). We found that SNAs emerged in both experiments, independently of whether SF was confounded or not with numerosity. Taken together, these findings suggest that SNAs cannot simply originate from SF power spectrum alone, and, thus, they rule out the brain’s asymmetric SF tuning as a primary cause of such an effect.
Historiography Issues and the History of Grain Warehouses in the First Half of the 19th Century (using the example of the Pskov Province)
Authors: Кошельков В.А. 
Published: February 2022

В настоящей статье освещается история зарождения и эволюции хлебозапасной системы в первой половине XIX века на примере Псковской губернии. Актуальность темы во многом предопределяется слабой изученностью проблемы создания продовольственных резервов в неурожайные годы в заявленные хронологические рамки. Автором предпринят историографический обзор избранной для исследования научной проблемы по трем основным периодам: дореволюционному, советскому и постсоветскому. В статье изложены основные этапы становления хлебозапасной системы, произведен подсчет количества и наполняемости хлебных магазинов в Псковской губернии. Подчеркнута важная роль запасных хлебных магазинов в Отечественную войну, когда хлеб поставлялся в качестве пожертвований на нужды русской армии. В статье отмечена высокая значимость хлебозапасной системы как неотъемлемого элемента продовольственной безопасности населения Псковской губернии.
The article focuses on the construction and evolution of warehouses intended for grain storage in the first half of the 19th century using the example of the Pskov region. The relevance of the issue is largely predetermined by the fact that the issue of constructing warehouses for grain storage during lean years in the 19th century is underinvestigated. The author attempts to perform a historiographical analysis of grain warehouse construction in pre-revolutionary Russia, during the Soviet era and in post-Soviet Russia. The article describes the major stages of grain storage system formation and provides a qualitative assessment of the grain storage system in the Pskov Province. The article underlines the significant role of grain warehouses during World War II, when grain was delivered to the front lines to satisfy the needs of Russian soldiers. The article underlines the outmost significance of grain storage as a non-negotiable element of food security of the Pskov Province.

Authors: Копылов Н.А. 
Published: February 2022

Выступление Чехословацкого корпуса против власти большевиков летом 1918 года стало толчком к масштабной Гражданской войне в России. После взятия чехами Самары и начала военных действий в Поволжье и Сибири эти регионы оказались отрезаны от Советской России. В статье рассматривается один из ключевых моментов начала Гражданской войны в Поволжье — взятия белыми войсками Симбирска. Используя архивные документы, автор представляет картину боев с точки зрения обеих противоборствующих сторон и раскрывает значение Симбирска как для советской власти, так и для ее противников.
The revolt of the Czechoslovak Legion against the Bolsheviks in the summer of 1918 provoked a large-scale Civil War in Russia. When the Legion entered Samara and started military actions in the Volga region and in Siberia, these regions were cut off from Soviet Russia. The article focuses on Simbirsk Operation, one of the key moments of the early stages of the Civil war in the Volga region. The author analyzes archival documents to reconstruct the military conflict from the point of view of the rivalry parties and to investigate the significance of Simbirsk for the Soviet authorities and for the opposition.

Published: February 2022

Background:

To assess the diagnostic performances of HRCT for COVID 19 pneumonia for efficient triage of patients, in comparison with RT-PCR reverse transcription polymerase chain reaction test.

Method:

It is retrospective comparative study conducted in Benazir Bhutto hospital affiliated with Rawalpindi medical university from March 25th to April 25th, 2021. HRCT of 500 patients were selected from central computer server and their RT-PCR results were also obtained from the HMS system of the hospital. HRCT were reported as “Definitely COVID positive”, “Possible COVID positive” or “COVID negative” by experienced radiologists. Sensitivity, Specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated using the final RT-PCR test as standard of reference.
Results:

RT-PCR test of 207 patients was positive, whereas 293 were reported negative. HRCT was reported as “Definitely COVID positive” in 222 cases (44.4 %), “Possible COVID positive” in 24 cases (4.8%) and “COVID negative” in 254 cases (50.8%). Comparing only Definitely COVID positive category with RT-PCR results sensitivity, specificity. PPV and NPV were 90.3%, 88%,84.2% and 92.8%

Conclusion:

CT chest is the most reliable, sensitive and rapid tool for triaging of patients as COVID positive or negative in busy emergency departments as compared to RT-PCR which is time consuming and has limitations such as faulty sampling technique, limited kits and variable sensitivity

Abstract

Background
The caesarean section rate is on the rise for various reasons. One of the reason is breech presentation . External cephalic version is a procedure to manipulate the baby from breech to cephalic presentation externally through the maternal abdomen under USG guidance . Success in ECV decreases the breech presentation and hence caesarean section rate .
Methods
This retrospective study was conducted by Wah Medical College in POF hospital from10 Oct 2015- 10 Oct 2019 after approval from the ethical committee .
It included 56 low risk singleton breech presentations from 36 wks- 40 wks after taking their informed consent While those with < than 36 wks (primis) and >40 wks gestation, refusal to ECV , with absolute contraindication to ECV& with medical and obstetric complications (ie scarred uterus, liquor <than 8 cm & > than 17 cm, fetal growth restriction, preclampsia, gestational diabetes & abnormal cardiotocography) were excluded from the study. ECV was performed by single obstetrician in labour room with facilities of cardiotocograph and emergency caesarean section. Cardiotocography of the fetus for 30-40 min was done just before & after the procedure of ECV. ECV was declared successful on cofirming head of the fetus occupying the lower uterine segment on ultrasound. .Number of successful ECVs & specific factors of the women & the baby (age . parity, amniotic fluid index ,type of breech, engagement of breech, position of back of baby) were chosen to observe their effect on success of ECV.
Results
External cephalic version was successful in 27 (48.2%) & unsuccessful in 29 (51.8%)of women .Multiparity , unengaged breech & type of breech (complete flexed) ( with p values .001, .000 & .001 respectively) had statistically significant positive association with successful external cephalic version.
Conclusion
ECV should be offered to all women with low risk breech presentations. Knowledge of factors predictive of ECV success can be utilized in selecting cases for ECV &counselling the women regarding the success and failure of ECV.

Objective: This study was conducted to compare epinephrine and salbutamol nebulization in emergency management of moderately ill children less than one and a half years old with bronchiolitis in terms of mean change in respiratory distress assessment instrument (RDAI) score.
Materials and Methods: Randomized controlled design was selected in this trial at the Department of Pediatrics, KRL Hospital Islamabad, Pakistan from 24th April 2016 to 24th October 2016. Sixty children with acute bronchiolitis, having a moderate degree of illness (RDAI 8-15) were included in this study. Patient were randomly allocated into Group A (epinephrine = 0.1 mL/kg in concentration of 1:10000) and Group B (salbutamol = 0.15 mg/kg combined with 3 mL 0.9% normal saline). It was delivered by a nebulizer and a face mask with a continuous flow of 6 L/min at100% oxygen. Data was collected on a predesigned performa and assessed with reference to mean change in RDAI score.
Results: The patients ' mean age in Group A and Group B were 10.57±4.22 and 11.63±3.14 months, respectively. The majority of the patients were males (56%). The mean RDAI score was insignificant between the two groups, both at baseline (11.57±2.21 in epinephrine group vs 11.3±2.14 in salbutamol group, p = 0.63) and 125 minutes (4.77±2.19 in Epinephrine group vs 5.43±1.69 in Salbutamol group, p = 0.19). However, when stratified according to age and gender, the mean RDAI score was found statistically significant among the 2-12 months age group (p = 0.0045) and female gender (p = 0.0052).
Conclusion: Epinephrine and salbutamol have similar effects in acute bronchiolitis when compared with regards to mean change in RDAI score.

To compare the analgesic and functional outcomes of intra-articular ketorolac with corticosteroids in patients of knee OA.
Methods:
In this randomized comparative study, we included patients of knee OA who were planned for intra-articular injections from January-2020 to December-2020 in the Department of Anesthesia and Pain Medicine at Rawalpindi Medical University. Patients were allocated to two groups using block randomization, each block contained 30 patients and received injection of either triamcinolone (Group T) or ketorolac (Group K). VAS score and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score were noted at 1 week, 1 month and at 3 months of injection.
Results:
Mean baseline WOMAC score was 46.60±5.64 in group K and 47.0±5.27 in group T (p-value 0.74). Mean WOMAC score was reduced significantly at 1st week and 1 months and 3 months follow-up in both groups, with insignificant statistical difference in group K and T (p-value 0.39, 0.18 & 0.15 respectively). Baseline VAS score was 7.02±1.34 in group K versus 7.27±1.03 in group T (p-value 0.36). VAS score was also reduced at 1 week, 1 month and 3 months follow-up, however the mean VAS at intervals was not statistically different between group K and T with p-value of 0.13, 0.08 and 0.49 respectively. Treatment was successful in 22 (55%) patients in group K versus 24 (60%) patients in group T (p-value 0.65).
Conclusion:
Intraarticular ketorolac has similar functional and analgesic outcomes as that of triamcinolone.
