Prevention of Postoperative Urethral Strictures by Irrigation with 5-Fluorouracil via a Modified Urinary Catheter.

Background and Objectives: Urethral strictures are the most common complications after surgical treatments of benign prostatic hyperplasia (BPH). Despite various preventive measures, the search for medications with antiproliferative activity and the development of surgical procedures to prevent the development of urethral strictures are still relevant. We evaluated the preventive efficacy of 5-fluorouracil against urethral strictures in patients undergoing surgery for BPH. Materials and Methods: A non-randomized clinical trial including 246 male patients with an average age of 70.0 ± 8.0 years was conducted. The main study group included 124 patients who, in addition to the standard treatment, received lavage with a 5-fluorouracil solution (1000 mg/20 mL per 500 mL of 0.9% isotonic saline) using a modified three-way urethral catheter. The monitoring of clinical, laboratory, and instrumental parameters was carried out 10 days, 3 months, and 6 months after surgery. Results: The evaluation of severity for dysuria symptoms in patients using the IPSS scale throughout the entire follow-up period showed a statistically significant decrease in ischuria and stranguria, prolongation of the interval between urinations, a decrease in intermittent urination, urinary incontinence, and straining before urination in the main group in comparison with the control patients. The patients of both study groups noted an improvement in the quality of life. It was found statistically significant decrease in the maximum urinary flow rate in the main group (p < 0.001). In the control group, after three months, four cases of urethral strictures and stenosis were recorded; after six months, this rate reached nine cases (7.3%), while in the main group, only one patient with infravesical obstruction was found (0.8%) (χ2 = 3.855, p < 0.05). Conclusions: The results of our study could indicate the effectiveness of the antiproliferative drug 5-fluorouracil in combination with use of a modified catheter in relation to the development of postoperative urethral strictures.

Incidence and Mortality of Cardiovascular Disease in the Republic of Kazakhstan: 2004-2017.

Background: We aimed to evaluate the impact of national health programs implemented in Kazakhstan from 2011 on CVD incidence and mortality. Methods: Incidence and mortality rates from CVD were studied in Kazakhstan from 2004 to 2017. The official data obtained from "Medinform" company were analyzed based on the annual population statistics. Results: There was an increase in the incidence of cardiovascular disease among the population of Kazakhstan from 1845.4 per 100,000 in 2004 to 2597.5 per 100,000 in 2017. This might be attributed to the implementation of the national health programs, which improved early CVD identification. Incidence of ischemic heart disease (IHD) was grown almost in all provinces of Kazakhstan during the study period. The mortality from cardiovascular disease had a considerable decline over the study period, in particular after 2010, it might be influenced by early diagnosis and provision of timely treatment. Conclusion: The experience of Kazakhstan national health programs shows improved identification of CVD and IHD and timely treatment for cardiovascular disease. A significant variation in incidence and mortality rates of cardiovascular disease was observed between the country provinces.

Association of radiation risk in the second and third generations with polymorphisms in the genes CYP1A1, CYP2E1, GSTP1 and changes in the thyroid.

BACKGROUND: To study the association of radiation risk in the 2nd -3rd generations with polymorphisms in the genes CYP1A1, CYP2E1, GSTP1 and changes in the thyroid. METHODS: 5 polymorphic gene variants (rs1048943, rs4646421, rs2070676, rs3813867, rs1695) were studied in 399 people living in the East Kazakhstan region in this research. 248 people of the 2nd - 3rd generation lived in the territory with radiation exposure in Abai, Borodulikha areas, and 151 people the comparison group lived in Kurchum district without radiation exposure comparable in sex and age with control group. RESULTS: The results show that there is a significant association of rs1048943 in exposed and unexposed groups (p < 0.003), and the absence of association of rs4646421, rs2070676, rs3813867, rs1695 in the studied groups. The mean value of thyroxine in carriers of the AG + GG genotype of rs4646421 is significantly lower than in AA genotype carriers (p = 0.04); no significant changes were found in genotypes' distribution with thyroid-stimulating hormone and anti-thyroid peroxidase indicators. Significant changes were in levels of anti-thyroid peroxidase between exposed and unexposed groups (p = 0.007). The thyroxine - thyroid-stimulating hormone levels were not significantly different in exposed and unexposed groups (p > 0.3). CONCLUSIONS: This study demonstrated the association of rs1048943 polymorphism with living in the radiation zone in the 2nd and 3rd generations for the first time. Thyroxine levels decrease was identified in the 2nd and 3rd generation residents of the exposed area, as well as a significant increase of anti-thyroid peroxidase occurs in individuals of the 2nd and 3rd generation living in areas with radiation exposure.

Trace element biomonitoring in hair and blood of occupationally unexposed population residing in polluted areas of East Kazakhstan and Pavlodar regions.

INTRODUCTION: Eastern and North-Eastern regions of Kazakhstan are considered to be environmentally disadvantaged due to industrial pollution and activity of the former Semipalatinsk Nuclear Test Site. Ferrous metallurgy is represented by the world's largest ferroalloy plant located in Aksu. In addition to a ferroalloy plant, Aksu is the home for the largest thermal power plant in Kazakhstan. OBJECTIVE: Biomonitoring of 31 hair and blood trace elements (Ag, Ba, Be, Bi, Cs, Co, Ce, Cr, Cu, Eu, Gd, Hf, In, La, Li, Mn, Mo, Nb, Nd, Pb, Sc, Sn, Tl, Th, U, V, W, Y, Yb, Zn, and Zr) in non-occupationally exposed population residing in polluted areas of East Kazakhstan and Pavlodar regions. METHODS: Five case groups, residing in the vicinity to the former Semipalatinsk Nuclear Test Site (Akzhar, Borodulikha, and Karaul) or in proximity to industrial plants (Aksu and Ust-Kamenogorsk) have been assessed vs. controls from a rural settlement in Kurchum. In total, 204 hair and blood samples were analyzed by inductively coupled plasma mass spectrometry. RESULTS: The observed blood concentrations of trace elements were in agreement with earlier studies on residents of industrially polluted areas. Elevated levels of blood Ba, Mn, Pb, V, and Zn were detected in residents of Aksu and Ust-Kamenogorsk. The elemental composition of head hair was characterized by greater stability between the study sites. CONCLUSION: Residency near the former Semipalatinsk Test Site could be considered as safe, while the environmental status of industrial settlements appears to be rather adverse.

Epidemiology of Geriatric Trauma in an Urban Kazakhstani Setting.

BACKGROUND: External causes of death are still among the main causes of death in the countries of the former Soviet Union. We studied epidemiology of injuries among elderly in a typical Kazakhstani city. METHODS: Data on all injuries among individuals aged 60 yr or older in the city of Semey (former Semipalatinsk) from 2010 to 2012 was collected from medical files. We present absolute numbers and incidence rates for the main ICD-codes in Chapters XIX and XX of ICD-10 by gender, ethnic background and place where the injury occurred. RESULTS: Altogether, there were 6065 injuries in 2010-2012. The overall incidence of increased from 4746.6 per 100000 in 2010 to 5577.7 per 100000 in 2012. Injuries to the elbow and forearm, injuries to the shoulder and upper arm, and injuries to the knee and lower leg were the most common and comprised 17.3%, 15.5% and 14.6% of all injuries, respectively. Falls constituted 82.2% of all injuries. Most injuries occurred at home and among ethnic Russians. CONCLUSION: The incidence and the absolute number of injuries among elderly in Semey increased during the study period in both men and women. Given that the population of Kazakhstan is getting older, injuries are expected to require more attention from the public health professionals and health authorities. More than four-fifths of traumas resulted from falls making this cause of injury the first target for preventive measures.

The Characteristics of Road Traffic Fatalities in Kazakhstan's Semey Region, 2006-2010: A Descriptive Retrospective Study.

BACKGROUND: Kazakhstan, a developing middle-income country, has the highest road traffic collision (RTC) mortality in the European Region. The aims of this study were to determine main characteristics of road traffic fatalities in Semey region, Kazakhstan and to compare findings with National data and middle-income European countries. METHODS: This descriptive surveillance study assesses RTC mortality rates and epidemiology in the Semey Region of East Kazakhstan Oblast. Data of all 318 road traffic fatalities form the Semey Regional Center for Forensic Medicine were analyzed for the 5-year period of January 1, 2006 through December 31, 2010. RESULTS: Over the study period, the average road traffic mortality in the Semey Region was 12.1 per 100,000 population with downward trend by 35.1% (p=0.002). The victims mean age was 37.1 (SD=17) years. Males predominated at 74.5%. Vehicle fatality was the most common mode of fatality at 61.3%. The majority of collisions, 53.1%, occurred on highways. Most victims, 67.3%, have died at the scene of collision; in 67.3% of fatalities, autopsies identified multiple injuries as cause of death. The high number of fatal collisions took place in "no snow" season (P<0.001), with an overall 5-years downward dynamic. CONCLUSION: High proportion of males, pedestrians and car occupants among road traffic fatalities; high proportion of death on scene in case of highway collisions are specifics for Semey region, Kazakhstan. These findings can be used to formulate preventive strategies to reduce fatalities and to improve the medical care system for road traffic fatalities.
