Objective ― This study was conducted to determine whether HbA1c is a predictor of short term mortality and morbidity after coronary artery bypass graft operation. Methods ― The coronary artery bypass graft operation was performed on the patients between January 2009 and January 2013. Each patient's medical record was retrospectively reviewed. The patients who were included in the study were evaluated in groups of 60. One group was comprised of nondiabetic patients, whose HbA1c level is below 6% (the control group 0), the other included diabetic patients with the HbA1c level is between 6-6.9% (the group 1) and the last group, group 2, included those patients with HbA1c level is equal or greater than 7%. Pre, peri and post operation data was compared. The deaths that occured in the first 30 days were evaluated as mortality and complications as morbitity. Results ― While mortality was not observed in the control group, one incident was observed in group 1 and 5 in group 2, which corresponds to 1.7% and 8.3% respectively. The mortality ratio in the group with patients whose HbA1c was greater or equal to 7% found statistically significant compared to the control group (P=0.02). The following parameters were observed in group 2 and were found statistically significant: the need for dialisis (25%, P<0.01), atrial fibrillation (33%, P=0.01), revision due to bleeding (10%, P=0.18), cerebrovascular event (16,7%, P=0.01), duration of mechanic ventilation (19.5±21.6, P=0.06), duration of hospital stay (approximately 9.91±5.35 days, P=0.01), infection in scar (53%, P<0.01), mediastenit (11%, P=0.01) and urinary tract infection (10%, P=0.01) Conclusion ― We concluded that in those diabetic patients that elective coronart artery bypass graft is applied, highly reactive HbA1c levels (HbA1c ≥7), may indicate morbitity in the early stages of post operation.

Objective; analysis of the dynamics of the main indicators of the ТВ epidemic in the Saratov region during the 5-year period. Material and Methods. The analysis of major indicators of epidemic (morbidity and mortality) in the Saratov region during the five years of observation. In the work a comparative evaluation of the parameters studied with analogical indicators in the Russian Federation was carried out. Results. During the period from 2009 to 2013 situation of tuberculosis epidemic in the Saratov region has positively stabilized. Over the past five years, the mortality rate in the region has decreased, while in the Russian Federation as a whole only on 25%, the incidence of the population in the region fell by 20%. It has been established that the later detection of a tuberculosis process leads to an increase in mortality and maintains reservoir of ТВ infection. Conclusion. In the Saratov region ТВ infection is thoroughly controlled. There is a well-established system for the detection, diagnosis, treatment and prevention of this specific process.

The study aims the influence of development of the acute postoperative pancreatitis at the early postoperative period; determine its influence at the frequency and spectrum of complications after abdominal surgery. Material and methods. The work is based on the results of the complex examination and surgical treatment of 1934 patients with various disorders of the digestive system (complicated duodenal ulcer and gastric ulcer, gastric cancer, the proximal and distal pancreatic cancer, colon cancer and postgastrectomy syndromes). The dependence of the overall incidence of postoperative complications, the number of complications per patient, and the number of infectious and inflammatory complications per patient, hospital mortality and length of postoperative hospital days for the development of acute postoperative pancreatitis were studied. Results. Acute postoperative pancreatitis is a leading cause of morbidity postoperative intra-abdominal operations. 97,8% of the cases of complicated early postoperative period of the operations on the organs of the abdominal cavity caused by the development of acute postoperative pancreatitis. Specific complications for the acute postoperative pancreatitis (satellite complications) were identified. Satellite complication had a clearly defined correlation with the development of the acute postoperative pancreatitis. The negative effect of acute postoperative pancreatitis on the severity of the postoperative period, on the morbidity, on the number of complications per patient, on the number of the infectious and inflammatory complications per patient, hospital mortality and on the duration of the postoperative hospital stay were found.

The aim of the research was to study the significance of morbidity of Parkinson's disease (PD) and mortality in Russian Federation in international comparisons. Material and Methods: In accordance with the purpose of the study the morbidity and mortality were analyzed in the Russian Federation on the basis of volumes "Morbidity in Russia" of the Ministry of Health of the Russian Federation in 2009-2012, "Human resources for health care institutions" of the Ministry of Health of the Russian Federation in 2012, tables С 51 about the mortality of subjects of the Russian Federation in 2012, data of mortality from Parkinson's disease in different countries in 2011, published by WHO. Results. The analysis of data on the morbidity patterns showed that in the Russian Federation in 2009-2012 there was an increase in general morbidity of adult patients with PD from 75.1 to 87.7 per thousand of populations. The data of primary morbidity in the adult population of the Russian Federation from PD also tend to increase from 8.0 to 8.5 per thousand of populations. The sharp fluctuations of mortality's data were revealed in subject of Russian Federation that was related of unreliable data. Mortality from PD in Russian Federation in 2012 was 0.31 per thousand of populations. Conclusion. The values in the study of general and primary PD's morbidity in the Russian Federation were lower than performance in international comparisons. PD's mortality in Russia was also lower than in other developed countries. Abidance by rules of selecting the primary cause of death (PCOD), confirmed by an automated system, where one of the causes is PD will make mortality statistics of PD reliable and internationally comparable.

Two field experiments were carried out using a custom built flow-through laboratory to test the effect of elevated pH on dreissenid mussels as a potential control method. Both experiments tested the ability of dreissenid pediveligers to settle under conditions of elevated pH and the long-term survival of adult dreissenids under the same conditions. The two experimental sites had different water quality and different species of dreissenids present. The settlement of quagga mussel pediveligers at the lower Colorado River was inhibited with increasing pH. At the maximum achieved pH of 9.1, there was approximately 90% reduction compared to the maximum settlement observed in the controls. Since the settlement was almost as low in pH 8.9 as at pH 9.1, the inhibition in settlement may have been due to the presence of a precipitate formed under high pH conditions rather than the increase in background pH. No mortality of quagga mussel adults was observed in the experimental pH levels at the lower Colorado River. At San Justo Reservoir, zebra mussel settlement decreased with increasing pH. New settlement was almost entirely absent at the highest pH tested (pH 9.6). The observed mortality of adult zebra mussels was low, but did tend to increase with increasing pH. We also tested the response of adult zebra mussels to short-term exposure to very high pH levels (i.e. pH 10, 11, and 12). Adult mussels in poor physical condition experienced 90% mortality after 12 hours at pH 12. For unstressed adult zebra mussels, 90% mortality was reached after 120 hours at pH 12. Significant mortalities were also observed both at pH 10 and pH 11. From this study, we conclude that pH elevation could be used both as a preventative treatment to eliminate settlement by dreissenid mussels and as an end of season treatment to eliminate adults. The high pH treatment would have to be tailored to the site water quality to prevent formation of precipitate during treatment and to minimize corrosive action on materials of construction.

A field experiment was conducted in 2009 using Lake Ontario water in a continuous flow through system to determine the impact of low pH on dreissenid mussel (zebra mussel, Dreissena polymorpha Pallas, 1771, and quagga mussel, Dreissena rostriformis bugensis Andrusov, 1897) settlement and survival in calcium rich waters. Raw water containing veligers was pumped to the field laboratory where the incoming water was divided into four streams. Three of the streams had the pH adjusted using phosphoric acid to pH 7.3, 7.1 and 6.9. The fourth stream was used as a control. Three replicates of each pH resulted in 9 treatment tanks and three control tanks. Three bags of caged adults were placed in each tank. Adult mortality of almost 40% was recorded at a pH of 6.9 after 10 weeks of exposure. Analysis of the weight/length relationship of adult mussels confirmed that for any given length the mussels were significantly lighter at all three pH levels when compared to the controls. Visually, erosion and perforation of the shells was noted, leading to the conclusion that the loss in weight was primarily due to loss of calcium from the shells of the adults. The visual loss of calcium was the greatest at a pH of 6.9. New settlement was essentially prevented at a pH of 7.1. Based on these results, downward adjustment of pH in calcium rich waters may be a viable treatment for prevention of dreissenid fouling in industrial cooling water systems and raw water conveyances.
