Summary
Total mesorectal excision (TME) is a standard surgical procedure for rectal cancer. Robotic surgery has the potential to minimize the disadvantages of laparoscopic rectal resection. Circumferential margin and macroscopic quality assessment of the resected specimen are the major prognostic factors for local recurrence of the disease. The aim of this study was to research the macroscopic assessment of the quality of TME after robotic-assisted rectal resections for rectal cancer performed in a single center. Data was prospectively collected about macroscopic assessment of the quality of TME in thirteen patients after robotic-assisted rectal resections for rectal cancer between 09.04.2014 and 31.12.2016. After all robotic TMEs, a pathologist made macroscopic assessment of the completeness of the mesorectal excision. The quality of TME was complete in 12 cases and nearly complete in one case. The circumferential and distal resection margins were negative in all cases. The mean number of harvested lymph nodes was nine. This study indicated that using robotic surgery for rectal cancer does not lead to worsening the quality of TME. Further studies in this field are necessary.

Summary
Affective disorders, including depression, are of great social importance and lead to serious everyday life infringement and disability. Affective disorders are one of the main causes of suicide causes. Anxiety disorders represent a variety of psychic disorders that often lead to disability. Anxiety and depression syndromes together are often seen in patients. Vitamin B12 (cobalamin) is the only vitamin containing cobalt. Our aim was to investigate, evaluate and compare depression and increased anxiety and serum Vitamin B12 level in patients with depression, in patients with Vitamin B12 deficiency anemia and healthy controls. We investigated 74 subjects – 38 patients and 36 healthy controls. Serum Vitamin B12 level was measured in all participants. It is assumed that normal ranges of Vitamin B12 level vary. The most recently accepted ones are 200 to 900 pg/ml. In cases of levels below 200 pg/ml, a therapy with vitamin B12 should be applied. On the other hand, the level necessary for normal biochemical processes is higher – 250 pg/ml. In our study, serum Vitamin B12 level in more than 50% of patients with depression/anxiety was below 200 pg/ml, and in more than 60% of these patients it was below 250 pg/ml.

Published: July 2018

Summary
A rare case is reported of twin-reversed arterial perfusion (TRAP) sequence in a triplet pregnancy, fetal intervention in the first trimester and pregnancy outcome. We report a case of TRAP sequence complication in dichorionic triamniotic triplet pregnancy, with a normally developing fetus and an acardiac fetus connected via arterio-arterial anastomoses in a monochorionic diamniotic twin pair and a separate fetus. TRAP sequence was diagnosed at 13 weeks in triplet pregnancy after in vitro fertilization (IVF) and embryo transfer of two blastocysts. Color Doppler assessment showed persistent arterial flow in the acardiac twin. Intrafetal laser coagulation was carried out at the time of the diagnosis, and the pregnancy outcome was two survivals at 36.4 weeks of gestation.

Abstract
Recently, an explosive growth has been observed in data traffic, which restricts the speed of exiting data communication network. To solve such problem, fiber optical-based optical communication is preferred choice. In this paper, a switch design is proposed to tackle contention problem in Optical Packet Switching (OPS) and data center networks. The proposed switch is compared with recently proposed switch design and advantages of proposed design are presented. To show superiority of the proposed design over earlier one, mathematical modeling is presented and expressions for noise figures and Bit Error Rate (BER) are derived. Using the mathematical framework, switch analysis is done in terms of BER and packet loss probability, and it has been found that power required for correct operation of the switch is lesser in comparison to earlier one. The effect of recirculation count on packet loss probability is detailed. The network layer analysis in terms of packet loss probability is also done using Monte Carlo simulation, and relation between physical and network layer parameters is also discussed.
Minimal genetic divergence among South American samples of the water opossumChironectes minimus: evidence for transcontinental gene flow?
Authors: Voss Robert S. , Jansa Sharon A. 
Published: July 2018

AbstractCytochromebsequences from South American specimens of the water opossumChironectes minimusexhibit uncorrected pairwise differences of 0.6% or less among samples collected thousands of kilometers apart (in Guyana, Bolivia and southeastern Brazil). Despite published evidence of population divergence from recent analyses of craniodental morphology, our results suggest extensive gene flow or recent range expansion across the South American landscapes currently occupied by this seldom-collected species.

Abstract
We hear more and more often that positive things make our life more beautiful and make us more optimistic. But is it really true? If until a few years ago, the products had usual names, now it is desired for them to have a catchy name that would remain in the memory of the target audience. In this research I have analysed the attitude that young people have towards energy drinks with negative brand names, the impact of these energy drinks on them and also the influence they have on the decisional act of purchase. Among secondary objectives was the establishment of the notoriety of energy drinks that have negative names in the case of young people. Another secondary objective consisted in the comparative analysis of the impact that energy drinks with negative names have on men and women. Also, for the determination of the attitude that young people have towards energy drinks with negative names, it was necessary to get one at the time the feelings, the conviction offered by these energizers and also the intent of buying them among young people.
Big Data Proprietary Platforms. The Case of Oracle Exadata

Published: July 2018

AbstractThe most prominent Big Data solutions – such as NoSQL systems, Hadoop Frameworks, Spark, etc. – have been open-sourced. Nevertheless, commercial providers have targeted niches of this huge market with products more or less viable and affordable. This paper addresses the problem of benchmarking Big Data platforms with a focus on Oracle Exadata solution provided by one the most important data technologies vendor. Many classical benchmark approaches, such as TPC-H, are based on a predefined set of queries, and consequently they are not prone to predictive modeling. By contrast, for the TPC-H benchmark schema, we generate a set of 500 random queries containing not only tuple filters (WHERE), but also tuple grouping (GROUP BY) and group filters (HAVING), we collected results of the queries execution on four Oracle Exadata settings. Query duration was the outcome variable. Various query parameters, such as the number of joins, the number of attributes of different types within SELECT and WHERE clauses, and also some environment metrics served as predictors. Results were interpreted using exploratory data analysis and also Multivariate Adaptive Regression Splines (MARS) for both predicting the performance and explaining the main drivers of the system performance.
Offset analgesia is not affected by cold pressor induced analgesia

Abstract

Background and aims
Offset analgesia (OA) is a pain modulating mechanism described as a disproportionately large decrease in pain intensity evoked by a minor decrease in stimulus intensity. Precise mechanisms of OA are still not elucidated and studies are needed to evaluate factors modulating OA. The aim of this study was to investigate OA before and during tonic cold pain (thought to induce descending inhibition), in a group of healthy volunteers.

Methods
A randomized, crossover study was performed in 17 healthy participants (8 males and 9 females). The OA paradigm lasted 35 s and was induced by the traditional method using thermal stimulation applied to the forearm. A constant control heat stimulus (CTL) paradigm was used as control to assess adaptation. Pain intensity was assessed continuously. For induction of tonic cold pain, the participants immersed their hand into 2°C water for 2 min. After 1 min and 25 s, the heat stimulation (OA or CTL paradigm) was repeated to assess the modulatory effect of the cold pressor test.

Results
It was possible to induce OA both before and during the cold pressor test. Tonic cold pain modulated the peak pain reported during both the OA (p=0.015) and CTL paradigms (p=0.001) reflecting endogenous pain modulation. However, the magnitude of OA was not modulated by tonic cold pain (p>0.05).

Conclusions
The offset analgesia magnitude was not modulated by simultaneously tonic cold pain, thought to reflect another endogenous pain modulation mechanism.

Implications
Neither offset analgesia magnitude nor adaptation were modulated by cold pressor induced endogenous analgesia. This could be explained by the fact, that offset analgesia was already at maximum in healthy participants. Hence, offset analgesia may not be a suitable assessment tool to investigate modulation induced by experimental methods or pharmacology in healthy participants.

Use of antithrombotic aids (ATA) significantly impact the prevention of life-threatening cardiovascular complications. ATA applications, however, are associated with a wide range of adverse digestive system responses. Due to, continuously growing clinical use of ATA this problem has become a current challenge of contemporary medicine.Purpose of the study was to evaluate the patterns of digestive system damage in patients receiving ATA.Materials and Methods. 672 patients were examined, 91.0% males, 46.7±17.4 years of age, who had digestive system changes that occurred due to ATA intake. 71 patients were admitted for treatment after gastrointestinal (GI) bleeding; other patients were hospitalized because of disorders of the digestive system or erosive and ulcerous changes of the digestive system detected by endoscopy. The following parameters were evaluated: GI bleeding sources, character of complaints, the endoscopic patterns due to intake of different ATAs (low doses of aspirin, warfarin, clopidogrel, dabigatran, rivaroxaban, low-molecular heparin, combined therapy), and of risk factors for GI complications.Results. The sources of GI bleeding (n=71) included gastric ulcers and/or erosions (39.4%), duodenum ulcers and/or erosions (21.1%), colon ulcers and/or erosions (28.2%), unknown (11.3%). The majority of 672 patients noticed various complaints: sensation of heaviness in epigastrium (62.8%), gastralgia (46.7%), burning sensation (34.3%). Endoscopy found erosive esophagitis (13.2%), ulcers in stomach and/or duodenum (11.6%), multiple ( 10) erosions of stomach or duodenum (17.1%), sporadic erosions of stomach or duodenum (24.4%). In 32.3% cases no erosive or ulcerous alterations were found. H. pylori was identified in 57.9% of patients. There was no significant difference in character of alterations in the upper digestive system between patients who received different ATA treatment, except of frequent erosive esophagitis in those patients who received dabigatran (16.8%). The elderly age ( 65 years), ulcer history, concomitant intake of NSAIDS, H. pylori presence, and smoking habit were associated with a higher occurrence of pathological alterations of digestive system. Presence of gastralgia did not correlate with the development of erosive and ulcerous alterations.Conclusion. In majority of patients who received ATA, the commonly observed erosive and ulcerous alterations in the digestive system might become a source of bleeding.

The purposeof the research: to analyze the quality of medical care of patients who are at risk of developing acute kidney injury.Materials and methods. The work is based on a retrospective analysis of medical records of 140 patients with an acute kidney injury developed during their stay the intensive care units, surgical and medical units of district hospitals the Irkutsk Oblast over the period from 2012 to 2017.Results. Inadequate assessment of the risk of an acute kidney injury was identified in 61% of patients. The most common inadequately assessed damaging factors were critical conditions (in 36% (50/140), sepsis (27% (38/140), and nephrotoxic drugs (19% (26/140). Among inadequately evaluated predisposing factors that could be managed, the following ones were most common: chronic heart disease (in 42% (59/140), dehydration/hypovolaemia (34% (47/140), chronic kidney disease (29% (41/140), and anemia (25% (35/140). In patients at risk of an acute kidney injury, an inadequate examination and inadequate maintenance therapy were found in 66% and 56% cases, respectively. Analysis of implementation of supporting therapy in patients at risk of an acute kidney injury the following misconducting events were revealed: (i) no optimal volumic and perfusion support (59% (82/140) and (ii) no cancellation of nephrotoxic and improperly prescribed drugs (31% (44/140).Conclusions. A good quality medical care restricted only by 24% of patients at risk of an acute kidney injury developed in the ICU, surgical and medical departments of district hospitals of the Irkutsk Oblast. The development of an acute kidney injury when exposed to nephrotoxic drugs and dehydration/ hypovolemia in 14% of cases was predictable and preventable.

This article draws on a broader research project that scrutinizes online / offline representational practices on transnational matchmaking websites featuring so-called 'Russian brides'. The central research question is: how are recurrent online representations related to gender (in intersection with other identity categories) co-constructed in the daily interactions between matchmaking staff and female clients on the floor of a marriage agency. To these aims, the researcher conducted participant observation in a transnational marriage agency in a Russian city and used linguistic ethnographic methodologies. The analysis for this article concentrates on the routine argumentative strategies that are used by matchmaking personnel to legitimate their intermediating role to Russian-speaking female clients in the case agency on the basis of in-depth interviews with agency staff and female clients. The analysis of discursive positioning in interviews with translators and female clients sheds light on the social order that is discursively created. This order is functional in defining and reproducing the commercial dependencies between matchmaking staff and female clients in a transnational globalized industry. This study demonstrates the way in which: (a) matchmaking personnel in the case study constructs subject positions in discourse – i. e. of transnational matchmaking experts and of female clients – by drawing on commonsensical public discourses of difference that encompass gender, age and nationality, and (b) matchmaking personnel affiliates with its clients by conceiving the matchmaking approach as an increasingly popular genre of self-improvement for Russian-speaking women.

It has been documented that the introduction of market economy institutions in Russia has disadvantaged Russian women, weakening their economic position and their power within the family. This paper investigates whether the introduction of the 2007 the Maternal Capital Law, which aims to promote fertility by granting Russian women a non-cash subsidy for having more than one child, affected the intrahousehold balance of power in Russian families. In order to investigate this hypothesis, the paper looks at changes in the ratio of family expenditure on children to spending on alcohol and tobacco before and after passing of the law. Data from the Russia Longitudinal Monitoring Survey (RLMS-HSE), 2002 to 2010, is used. The estimated regression models employ the difference-in-difference methodology and are based on Lundberg, Pollack and Wales, who researched a similar policy shift in the UK in 1970s. The results demonstrate that the year 2008 was a critical turning point: starting with 2008 the ratio of family expenditure on children to spending on alcohol and tobacco increased for families with two or more children (the results are statistically significant). After 2007, on average, expenditure on children increased by fifty-nine roubles per every ruble of alcohol and tobacco expenditures (mesearured in 2002 roubles), nearly doubling. The effect in families with a husband not holding a college degree was shown to be larger and more siginifcant than in families with college-educated husbands. It is concluded that the 2007 Law has had a positive impact on the bargaining power of Russian women.
