Authors: Perehodov Sergey N. , Sakvarelidze Nikoloz Yu. , Tsakhilova Svetlana G. , Lunina Elena V. 
Published: April 2021

Coronavirus infection caused by a new strain of SARS-CoV-2 virus contributed to an increase in the number of infectious
patients. The Ministry of Health of the Russian Federation and Rospotrebnadzor took over the organization of work to combat
the pandemic. In Moscow, medical and preventive events were organized by the Government of the capital and the Department
of Health of the city. As soon as possible, it was decided to reassign medical institutions to infectious hospitals for the treatment of patients with COVID-19 or with suspicion of it. “Maternity hospital No. 8” – the branch of State Clinical Hospital named after V. P. Demikhov was redesigned as a hospital on March 13, 2020. The decision was due to the presence of isolated boxes and an intensive care unit in the institution. The task was solved in one day: the first patients with coronavirus infection were admitted to the hospital for medical care at 17:00 on March 13, 2020.

Blood cyst of the mitral valve – is it common? Case report
Authors: Ionac Ioana , Mornos Cristian , Feier Horea , Dema Alice , Ionac Adina 
Published: April 2021

Abstract
Cardiac blood cysts are benign tumors, usually congenital malformations, found on the endocardium, particularly along the closing lines of the heart valves. Blood cysts of the heart are commonly reported at postmortem findings in infants and they are very rare in adults. We report a case of a 39 year old patient, who was incidentally discovered during echocardiography having a blood cyst attached to the ventricular face of the anterior mitral valve and to the mitral chordae. During surgery, the cystic mass was resected. Mitral valvuloplasty was successfully performed and the patient had an uneventful recovery. Blood cysts are rarely reported, thus there is no consensus or guidelines for the optimal management of the asymptomatic cases. Although our patient was asymptomatic and the cyst did not interfere with the cardiac function, together with the heart team, we chose the surgical resection of the cardiac mass in order to prevent possible complications.

Abstract
Functional or secondary tricuspid regurgitation (FTR) is a progressive disease with a significant negative impact on patient morbidity and mortality. Recently, atrial fibrillation (AF) has been recognized as a cause of FTR (with/without coexisting functional mitral regurgitation) by promoting right atrial (RA) remodeling and secondary tricuspid valve (TV) annulus dilation, even in the absence of right ventricular (RV) dilation or dysfunction. This distinct form of FTR has been called “atriogenic” or “atrial”. Recent evidence suggests that the RA is an important player in FTR pathophysiology not only for patients with AF, but also for those in sinus rhythm. Preliminary reports on atrial FTR show that cardioversion with documented maintenance of sinus rhythm promotes TV annulus and RA reverse remodeling and may significantly reduce FTR severity at follow-up. Large-scale studies on the prognostic benefits of rhythm vs rate-control strategy in atrial FTR patients are needed to substantiate specific guidelines indications for this subset of patients.
Left atrial appendage morphology and the risk of stroke

Published: April 2021

Abstract
In patients with non-valvular atrial fibrillation (AF) the risk of stroke is five times higher than in patients with sinus rhythm. Moreover, stroke is likely to be more severe in the AF patient population. Left atrial appendage (LAA) is the most common source of emboli in AF-related stroke. LAA thrombus is present in 15% of AF patients. Therefore, numerous studies aimed to evaluate the role of LAA structure and function in stroke formation. Higher LAA volume and bigger LAA orifice have been reported to be associated with increased risks of stroke. Moreover, not only the size, but also the shape of the LAA influences thrombus formation. The presence of an obvious bend in the proximal part of the dominant LAA lobe, described as chicken wing LAA morphology has been reported to be protective against stroke. However, other studies are not consistent with this finding and there is no consensus about LAA morphology categories. LAA has reservoir, contractile, electric and endocrine functions, that can provide essential information about the risk of clot formation and embolic events. Decreased LAA flow velocity, reflecting lower LAA contractility has been described to be associated with higher stroke risk. All in all, even if the LAA plays an important role in stroke formation, there are controversial literature data, therefore further studies are needed to evaluate the underlying mechanisms.

Published: April 2021

Low Birth Weight Babies (LBW) are babies born less than 2,500 grams. The LBW birth rate at the Ciamis District Regional General Hospital is quite high. One of the efforts to reduce the incidence of LBW is to improve the antenatal care at least 4 times during pregnancy.

This study uses a type of quantitative analytical research using the Cross Sectional approach. The population in the study were all mothers who gave birth at the Ciamis District Regional General Hospital. The study sample was 30 people.

The results showed that the completeness of antenatal care (ANC) was mostly in complete category, namely 17 people (56.7%). LBW incidence was mostly in the category of LBW as many as 17 people (56.7%). There is a relationship between the completeness of antenatal care (ANC) and the incidence of low birth weight because the values of ?> ? values (0.05> 0.007) and incomplete antenatal care (ANC) have a chance of 10.083 (10) times greater than the incidence of low birth weight.
The conclusion in this study is that there is a significant relationship between the completeness of antenatal care (ANC) and the incidence of LBW at the District General Hospital of Ciamis

Suggestions are expected to improve ANC services by providing counseling to patients about the importance of ANC visits

The conclusion in this study is that there is a significant relationship between the completeness of antenatal care (ANC) and the incidence of LBW at the District General

Researching visually using visual ethnographic methodology
Authors: Ratna Kumar Dr. J. Vijay 
Published: April 2021

According to Sarah Pink (2001) defines the visual ethnographic as the use of visual images and technologies such as video, film, photography, art, drawing and sculpture in qualitative social research to both produce and represent knowledge. It includes using the visual as a documenting tool to produce visual records, in interviews, to elicit comments from informants, in participant observation to research ways of seeing and understanding, analysing visual and material culture and using visual media to represent the findings of such research.
Visual ethnography deals with the visual and perceptual study of culture, material culture and forms of human behaviour in different communities and environments.
Visually we can communicate knowledge and experience and ideas in ways that we never express in written words or spoken words, in social research, the visual is gaining significance as a research method.

Authors: Tlałka Dariusz , Sliwinska Elwira , Kruk Jerzy 
Published: April 2021

Abstract
During field studies in 2019 in the Beskid Śląski mountain range in southern Poland, one individual morphologically resembling
Polystichum setiferum
was found. Nuclear DNA content analysis confirmed the species identity. The new stand of
P. setiferum
corresponds to historical literature reports and herbarium specimens from the Czech Republic and Poland, and extends the northeastern limit of the distribution of this species. As the historical stands in both countries have not been confirmed, the newly discovered stand is at present strongly isolated, as the nearest extant locations of
P. setiferum
in Austria, southern Hungary, and western Romania are nearly 500 km away. Therefore, this unique stand deserves special attention and protection.
The Design of the “Dynabout” - The Dynaplane Concept Applied to the Design of a More Efficient Outboard Powered Recreational Runabout
Authors: Parkyn Nicholas D. 
Published: April 2021

The Dynaplane concept has many real advantages and benefits, but has not enjoyed the acceptance that it deserves. The Dynaplane concept was originally conceived for application to craft over 20ft in length powered by inboard engine with drive leg mounted well forward of transom, a transom mounted rudder and v-shaped stern foil configuration.
The author has revised, revisited and simplified some aspects of the original Dynaplane concept to realize its application to a 16.5ft (5m) outboard powered “runabout” style craft which should appeal to the recreational boating market.
Since research and previous application by Eugene Clement was on larger craft, some data and aspects were extended for applicability to the smaller sized version.
Design software “Dyna_Designer” applicable to Dynaplane was developed and used during the design process. Powering, stern foil configuration, steering and step ventilation were re-worked to reduce complexity. During the design process the author was privileged to have the support of and input from Eugene Clement. The final design documents were made available to Eugene Clement by the author and his responses were positive.
This paper describes some aspects of the development work done to date by the author in realizing a runabout design using the Dynaplane concept.

Background
Gastric cancer (GC) is a heterogeneous disease that encompasses various molecular subtypes. The molecular mutation characteristics of circulating tumor DNA (ctDNA) in advanced gastric cancer (AGC), especially the clinical utility of TP53 mutation and MET amplification in ctDNA need to be further explored.

Objectives
The aim of this study was mainly to assess the clinical utility of TP53 mutation and MET amplification in ctDNA as biomarkers for monitoring disease progression of AGC.

Patients and Methods
We used multigene NGS-panel technology to study the characteristics of ctDNA gene mutations and screen the key mutant genes in AGC patients. The Kaplan-Meier method was used to calculate the survival probability and log-rank test was used to compare the survival curves of TP53 mutation and MET amplification in ctDNA of AGC patients. The survival time was set from the blood test time to the follow-up time to observe the relationship between the monitoring index and tumor prognosis.

Results
We performed mutation detection on ctDNA in 23 patients with AGC and identified the top 20 mutant genes. The five most frequently mutated genes were TP53 (55%), EGFR (20%), ERBB2 (20%), MET (15%) and APC (10%). TP53 was the most common mutated gene (55%) and MET had a higher frequency of mutations (15%) in our study. Kaplan-Meier analysis showed that patients with TP53 mutant in ctDNA had shorter overall survival (OS) than these with TP53 wild (P < 0.001). The Allele frequency (AF) of TP53 mutations in patient number 1 was higher in the second time (0.94%) than in the first time (0.36%); the AF of TP53 mutations in patient number 16 was from scratch (0∼0.26%). In addition, the AF of TP53 mutations in patients who survive was relatively low (P = 0.047). Simultaneously, Kaplan-Meier analysis showed that patients with MET amplification also had shorter OS than these with MET without amplification (P < 0.001).

Conclusion
TP53 and MET are the two common frequently mutant genes in ctDNA of AGC patients.TP53 mutation and MET amplification in ctDNA could predict disease progression of AGC patients.

The International Journal Of Alcohol And Drug Research, 6(1), 69-76. doi:http://dx.doi.org/10.7895/ijadr.v6i1.237Introduction: Studies exploring psychoactive substance use (PASU) among adolescents report a variety of both intrapersonal and interpersonal negatively and positively reinforcing factors. While existing studies have looked at factors affecting PASU among adolescents in general, little has been done to explore such factors in schools.Objective: This paper examines the factors that influence PASU among adolescents in Ugandan public schools.Methods: The study generated data from 12 focus group discussions (FGDs), based on a qualitative, cross-sectional exploratory design using purposive sampling. We used a focus group guide based on the question “What factors influence use ofResults: All focus groups noted peer pressure as the strongest factor influencing use of substances in schools, with relief from domestic stress being identified as the second strongest factor. The FGDs tackled other factors related to PASU in public schools in Uganda, though not to as big of an extent.Conclusion: Present study results generally seem to suggest that PASU among adolescents in public schools is a result of the interaction between adolescents, the substances in question, and the environment in which those adolescents live.
