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%) (χ
2 = 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. [ABSTRACT FROM AUTHOR]- Published

Introduction. Coronavirus infection is a risk factor for vascular thrombosis. This is of particular importance for patients undergoing myocardial revascularization since this infection can be a trigger for the formation of restenosis in the area of a previously implanted coronary stent. Understanding the risk factors for stent thrombosis and restenosis is of particular importance in individuals at risk for adverse outcomes. The rarity of such situations makes the present study unique. Objective. Studying the peculiarities of restenosis and thrombosis of the coronary arteries in patients after coronavirus infection. Methods. The study was performed in the Department of Cardiovascular Surgery of Emergency Hospital, Semey City, in 2021. We have examined the medical records of 10 consecutive patients with restenosis of coronary arteries after coronavirus infection and 10 matched-by-age patients with similar restenosis of coronary arteries who did not have coronavirus infection as a comparison group. To determine statistically significant differences between independent samples, we calculated the Mann–Whitney U test. Results. The average age of patients was 65.7 years. Only one case was classified as early restenosis (within 8 days of previous revascularization), two cases represented late restenosis, and seven cases were very late restenoses. In 70% of cases, restenosis was localized in the left anterior descending artery, in 30% of cases, it was in the right coronary artery, and in 40% of cases, it was in the left circumflex artery. In comparison with patients who did not have a coronavirus infection, there were statistically significant differences regarding IgG (P < 0.001) and fibrinogen (P = 0.019). Conclusion. Patients with myocardial revascularization in the past have a higher risk of stent restenosis against the background of coronavirus infection due to excessive neointimal hyperplasia, hypercoagulability, increased inflammatory response, and endothelial dysfunction.

NEURAL transmission ,FOOD consumption ,NEUROTRANSMITTERS ,PARKINSON'S disease ,NEURONS ,FOOD habits - Abstract
Neurotransmitters (NTs) are biologically active chemicals, which mediate the electrochemical transmission between neurons. NTs control numerous organic functions particularly crucial for life, including movement, emotional responses, and the physical ability to feel pleasure and pain. These molecules are synthesized from simple, very common precursors. Many types of NTs have both excitatory and inhibitory effects. Neurotransmitters' imbalance can cause many diseases and disorders, such as Parkinson's disease, depression, insomnia, increased anxiety, memory loss, etc. Natural food sources containing NTs and/or their precursors would be a potential option to help maintain the balance of NTs to prevent brain and psychiatric disorders. The level of NTs could be influenced, therefore, by targeting dietary habits and nutritional regimens. The progressive implementation of nutritional approaches in clinical practice has made it necessary to infer more about some of the nutritional NTs in neuropsychiatry. However, the importance of the intake of nutritional NTs requires further understanding, since there are no prior significant studies about their bioavailability, clinical significance, and effects on nerve cells. Interventional strategies supported by evidence should be encouraged. [ABSTRACT FROM AUTHOR]

VITAMIN D metabolism ,CALCIUM metabolism ,VITAMIN K2 ,VITAMIN D receptors ,BONE growth ,VITAMIN K ,VITAMIN D deficiency - Abstract
Calcium is involved in bone metabolism, regulation of nerve signaling, and release of neurotransmitters. Phosphorus is a structural component of ATP, participates in metabolic energy regulation, and ensures stability to biological membranes and cells. Vitamin D and vitamin K are important for intestinal absorption and renal excretion of calcium and phosphorus. Vitamin D plays a regulatory role in bone formation, carbohydrate metabolism, immune responses, and cardiovascular regulation. Research has linked vitamin D deficiency to the development of diabetes mellitus, hypertension, cancer, and osteoporosis. Vitamin K has been associated with a reduced risk of osteoporosis, cancer, and cardiovascular diseases (due to improved vascular elasticity). This review highlights the importance of vitamins D and K in the metabolism of calcium and phosphorus and explores various molecular mechanisms that help maintain the system's mineral homeostasis. Moreover, the paper reviews the enzyme nattokinase's role in thrombotic prevention due to its fibrinolytic activity. [ABSTRACT FROM AUTHOR]

MERS coronavirus ,COVID-19 ,SARS virus ,ELECTRONIC cigarettes ,SARS-CoV-2 - Abstract
There was a dramatic spread of three novel coronaviruses (CoVs) – severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), and SARS-CoV-2 – from the beginning of the twenty-first century. All three infections share similar pathogenesis and clinical presentation, and human-to-human transmission is the most frequent transmission mode for all three CoVs, which spread through respiratory droplets, by direct contact with contaminated surfaces or by inhaling aerosols. Nosocomial transmission plays a major role for SARS-CoV and MERS-CoV but appears to be less critical for SARS-CoV-2. Coronaviruses will very likely continue to be a source of new acute respiratory infections in the future. This is why it is needed to better understand the whole spectrum of factors that underlie CoV disease outbreaks. Although a search for specific treatment and vaccine development has to be continued, a strategic preparedness and plan of action should be envisaged in advance. This review discusses the current knowledge of SARS-CoV, MERS-CoV, SARS-CoV-2 epidemiological determinants and emphasizes public health interventions that could help in the fight against them.

Background: Anthropogenic risk factors contribute worldwide to an unfavorable environmental situation, which in the population can lead to cancer and other environmental-related diseases. Heavy metals accumulate in tissues and affect human health. Objectives: This review evaluates data for the possible role of uranium (U), barium (Ba), and lead (Pb) in the cancer development in people living in the Malwa Region of Punjab, India. Methods: A literature search was performed using the databases PubMed, Google Scholar, and Scopus. Publications in English were included. Preference was given to studies of high methodological quality (systematic reviews and surveys of studies of various designs). The results of cross-sectional studies were taken into account. Discussion: A study has shown that cancer patients in the Malwa region of Punjab, India have unexpectedly high concentrations of U, Ba, and Pb in hair. We hypothesize that higher hair concentrations of U and other bone-seeking elements in hair of cancer patients may be due to the release of these elements from the skeleton, partly because of the patients age (following the menopause in women) and partly due to disease factors such as bed rest, bone metastases, and enhanced glucocorticoid secretion. Conclusions: Further research is needed to distinguish the effect of age on bone-seeking elements from real disease associations, regardless of the relationship with the pathology is a causal one or not.

Mercury (Hg), a highly toxic environmental pollutant, shows harmfulness which still represents a big concern for human health, including hazards to fertility and pregnancy outcome. Research has shown that Hg could induce impairments in the reproductive function, cellular deformation of the Leydig cells and the seminiferous tubules, and testicular degeneration as well as abnormal menstrual cycles. Some studies investigated spontaneous abortion and complicated fertility outcome due to occupational Hg exposure. Moreover, there is a relation between inhaled Hg vapour and reproductive outcome. This MiniReview evaluates the hypothesis that exposure to Hg may increase the risk of reduced fertility, spontaneous abortion and congenital deficits or abnormalities. [ABSTRACT FROM AUTHOR]

BARIATRIC surgery ,SLEEVE gastrectomy ,IRON deficiency ,GASTRIC bypass ,IRON supplements ,OBESITY ,MORBID obesity - Abstract
Iron deficiency (ID) is particularly frequent in obese patients due to increased circulating levels of acute-phase reactant hepcidin and adiposity-associated inflammation. Inflammation in obese subjects is closely related to ID. It induces reduced iron absorption correlated to the inhibition of duodenal ferroportin expression, parallel to the increased concentrations of hepcidin. Obese subjects often get decreased inflammatory response after bariatric surgery, accompanied by decreased serum hepcidin and therefore improved iron absorption. Bariatric surgery can induce the mitigation or resolution of obesity-associated complications, such as hypertension, insulin resistance, diabetes mellitus, and hyperlipidemia, adjusting many parameters in the metabolism. However, gastric bypass surgery and sleeve gastrectomy can induce malabsorption and may accentuate ID. The present review explores the burden and characteristics of ID and anemia in obese patients after bariatric surgery, accounting for gastric bypass technique (Roux-en-Y gastric bypass—RYGB) and sleeve gastrectomy (SG). After bariatric surgery, obese subjects' iron status should be monitored, and they should be motivated to use adequate and recommended iron supplementation. [ABSTRACT FROM AUTHOR]

PERSIAN Gulf syndrome , *URANIUM , *DNA damage , *VETERANS , *MILITARY personnel - Abstract
Indications of proximal tubule effects have been observed in recent surveillance study of Gulf War veterans exposed to depleted uranium (DU). This gives some support for the suspicion that DU may represent one of the causes for the so-called Persian Gulf syndrome. Proposed effects may be especially harmful if the toxicity hits the mitochondrial DNA since the mitochondria lack the nucleotide excision repair mechanism, which is needed for repairing bulky adducts that have been associated with DU. It is a plausible working hypothesis that a significant part of the symptoms from various organs, which have been observed among veterans from Gulf War 1 and that have been grouped under the name of the Persian Gulf syndrome, may be explained as a consequence of mitochondrial DNA damage in various cell types and organs. Interpretation of observations, on military personnel and civilians after Gulf War 1, is associated with difficulties because of the abundance of potential confounding factors. The symptoms observed on veterans from Gulf War 1 may be attributed to a multiplicity of substances functioning directly or indirectly as mitochondrial mutagens. A concise analysis of the cascade of toxic effects initiated by DU exposure in the human body is the subject of this article. • Depleted uranium (DU) is both a chemo-toxic and a radiotoxic element. • DU may be one of the causes for the so-called Gulf War illness (GWI). • Proposed effects of DU may be especially harmful if mitochondrial DNA is damaged. • The symptoms of GWI may be explained by the influence of mitochondrial mutagens.

Abstract This study examines the association between environmental radiation exposure and essential hypertension in a series of investigated geographical districts adjacent to the Semipalatinsk nuclear test site in Kazakhstan. The sample consists of 2000 volunteers participants in screening examinations in three administrative districts close to the nuclear test site, which was carried out as part of the Government Programs on Environmental Health Hazard. The cross-sectional study compares prevalence ratios in a population sample with long-term exposure in the low and intermediate dose range. Age-adjusted odds ratios for hypertension were found significantly increased with higher exposure groups. After accounting for main cardiovascular risk factors into the model and stratifying by gender, the prevalence odds ratios for radiation remained significantly increased, with a significant dose-response effect observed for some but not all subgroups. The results support existing evidence of cardiovascular health effects of radiation exposure and of persisting environmental health issues that require attention in both epidemiological surveys and healthcare provision. Highlights • Large territories of Kazakhstan were exposed to radiation due to nuclear tests. • Nuclear tests lead to long-term exposure of the population in the low dose range. • There is an association between environmental radiation exposure and hypertension. • Screening allows us to diagnose CVD in the irradiated people in the early stages. • Radiation health effects should be considered in health services planning.

- Abstract
Objective: Consultation is an important and necessary aspect of patient care in the emergency department. We prospectively examined difficulties during the consultation process between paramedics and providers in emergency departments in Kazakhstan., Methods: The paramedics were interviewed using various platforms and face-to-face meetings. Questionnaires were administered to paramedics to gather feedback on the current consultation process. In our survey, 202 paramedics of ambulance from the cities of Semey, Pavlodar, and Ust-Kamenogorsk, located in the North and East of Kazakhstan took part., Results: Serious barriers to effective consultation were identified during consultations with cardiologists, pediatricians, and traumatologists. Weekends, as well as nighttime, are associated with more consultation difficulties. The most common problems for paramedics are non-attendance of the consultant, refusal of hospitalization by the consultant, and referral to other specialists and departments. More than 40% of the respondents noted the desire to share responsibility for the patient with medical consultants, which indicates uncertainty in their own knowledge due to the limited work experience of the majority of respondents., Conclusion: Barriers that arise during the consultation process of patients with emergency conditions can lead to unfavorable outcomes. Strategies to address these barriers are needed to improve the quality of patient care. This review aims to understand and evaluate the issues that arise during the consultation process., Competing Interests: The authors report no competing interests for this work., (© 2023 Ygiyeva et al.)

- Abstract
Background: Obesity is known to be a multifactorial disease. In its pathogenesis, different factors such as chronic inflammation, oxidative stress, insulin resistance, genetic factors, environmental effects, vegetative disturbance, and unbalanced nutrition play a significant role., Methodology: This study describes the association of obesity and insulin resistance with chronic inflammation, genetic, and epigenetic factors. Previous literature has been reviewed to explain the relation of obesity with those factors involved in chronic low-grade inflammation and insulin., Results: Obesity is associated with a decrease in ghrelin secretion, elevated plasma leptin levels, oxidative stress, increased macrophage phagocytic activity, and the induction of proinflammatory synthesis of cytokines and interferon-gamma. Obesity is linked to decreased levels of cytochrome P450 (CYP) enzymes and impaired detoxification processes. Deficiency of vitamins and minerals can also play a significant role in the development of oxidative stress and chronic inflammation in obesity. There is evidence of associations between a genetic predisposition to obesity in children with elevated levels of certain miRNAs., Conclusion: The purpose of the present review is an analysis of the multiple factors associated with obesity., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Intestinal hyperpermeability is a complex metabolic process mediated by different pathways in close relation to the gut microbiota. Previous studies suggested that the gut microbiota is involved in different metabolic regulations, and its imbalance is associated with several metabolic diseases, including obesity. It is well known that intestinal hyperpermeability is associated with dysbiosis, and the combination of these two conditions can lead to an increase in the level of low-grade inflammation in obese patients due to an increase in pro-inflammatory cytokine levels. Inflammatory bowel syndrome often accompanies this condition causing an alteration of the intestinal mucosa and thus reinforcing the dysbiosis and gut hyperpermeability. The onset of metabolic disorders depends on violations of the integrity of the intestinal barrier as a result of increased intestinal permeability. Chronic inflammation due to endotoxemia is responsible for the development of obesity. Metabolic disorders are associated with dysregulation of the microbiota-gut-brain axis and with an altered composition of gut flora. In this review, we will discuss the mechanisms that illustrate the relationship between hyperpermeability, the composition of the gut microbiota, and obesity., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Background: Coronavirus disease 2019 (COVID-19) pandemic entered Kazakhstan on 13 March 2020 and quickly spread over its territory. This study aimed at reporting on the rates of COVID-19 in the country and at making prognoses on cases, deaths, and recoveries through predictive modeling. Also, we attempted to forecast the needs in professional workforce depending on implementation of quarantine measures., Methods: We calculated both national and local incidence, mortality and case-fatality rates, and made forecast modeling via classic susceptible-exposed-infected-removed (SEIR) model. The Health Workforce Estimator tool was utilized for forecast modeling of health care workers capacity., Results: The vast majority of symptomatic patients had mild disease manifestations and the proportion of moderate disease was around 10%. According to the SEIR model, there will be 156 thousand hospitalized patients due to severe illness and 15.47 thousand deaths at the peak of an outbreak if no measures are implemented. Besides, this will substantially increase the need in professional medical workforce. Still, 50% compliance with quarantine may possibly reduce the deaths up to 3.75 thousand cases and the number of hospitalized up to 9.31 thousand cases at the peak., Conclusion: The outcomes of our study could be of interest for policymakers as they help to forecast the trends of COVID-19 outbreak, the demands for professional workforce, and to estimate the consequences of quarantine measures., Competing Interests: The authors have no potential conflicts of interest to disclose., (© 2020 The Korean Academy of Medical Sciences.)

- Abstract
As a major neurodevelopmental disorder, Autism Spectrum Disorder (ASD) encompasses deficits in communication and repetitive and restricted interests or behaviors in childhood and adolescence. Its etiology may come from either a genetic, epigenetic, neurological, hormonal, or an environmental cause, generating pathways that often altogether play a synergistic role in the development of ASD pathogenesis. Furthermore, the metabolic origin of ASD should be important as well. A balanced diet consisting of the essential and special nutrients, alongside the recommended caloric intake, is highly recommended to promote growth and development that withstand the physiologic and behavioral challenges experienced by ASD children. In this review paper, we evaluated many studies that show a relationship between ASD and diet to develop a better understanding of the specific effects of the overall diet and the individual nutrients required for this population. This review will add a comprehensive update of knowledge in the field and shed light on the possible nutritional deficiencies, metabolic impairments (particularly in the gut microbiome), and malnutrition in individuals with ASD, which should be recognized in order to maintain the improved socio-behavioral habit and physical health., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
The prevalence of Type 2 Diabetes Mellitus (T2DM) is internationally ever-growing. Therefore, prevention, diagnostics, and control of insulin resistance and T2DM are of increasing importance. It has been suggested that mechanisms leading to insulin resistance and diabetes and its complications include high intake of refined and energy-rich food, which is presumed to be accompanied by suboptimal intake of trace elements, such as Zinc (Zn), Selenium (Se), Chromium (Cr), and Copper (Cu), which are essential and crucial for various biological processes. The purpose of this review is to highlight the role of Zn, Se, and Cu in T2DM. Diabetes seems prevalent when Zn, Se, and Cu are deficient, which may result from excessive intake of refined food. The literature search was conducted in PubMed and Scopus, supplemented with the reference lists of relevant articles and a Google Scholar search. We critically assessed all relevant citations, both review and research papers in English. The search terms that were used included Zn, Cu, diabetes, and diabetes mellitus. Research has shown that Zn, Se and Cu are involved in the pathogenesis of diabetes, but these trace elements can in excessive amounts be toxic. Zinc appears to activate key molecules that are involved in cell signaling, which maintain the homeostasis of glucose. Zinc also regulates insulin receptors, prolong the action of insulin, and promote healthy lipid profiles. Copper in excess can create oxidative stress, which is a factor in the onset and the progression of T2DM. Abnormal Zn and Cu metabolism appears to accompany and may also cause diabetes complications., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
The concentrations of metals in the environment are still not within the recommended limits as set by the regulatory authorities in various countries because of human activities. They can enter the food chain and bioaccumulate in soft and hard tissues/organs, often with a long half-life of the metal in the body. Metal exposure has a negative impact on bone health and may result in osteoporosis and increased fracture risk depending on concentration and duration of metal exposure and metal species. Bones are a long-term repository for lead and some other metals, and may approximately contain 90% of the total body burden in birds and mammals. The present review focuses on the most common metals found in contaminated areas (mercury, cadmium, lead, nickel, chromium, iron, and aluminum) and their effects on bone tissue, considering the possibility of the long-term bone accumulation, and also some differences that might exist between different age groups in the whole population., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
The risk assessment of mercury (Hg), in both wildlife and humans, represents an increasing challenge. Increased production of Reactive Oxygen Species (ROS) is a known Hg-induced toxic effect, which can be accentuated by other environmental pollutants and by complex interactions between environmental and genetic factors. Some epidemiological and experimental studies have investigated a possible correlation between brain tumors and heavy metals. Epigenetic modifications in brain tumors include aberrant activation of genes, hypomethylation of specific genes, changes in various histones, and CpG hypermethylation. Also, Hg can decrease the bioavailability of selenium and induce the generation of reactive oxygen that plays important roles in different pathological processes. Modification of of metals can induce excess ROS and cause lipid peroxidation, alteration of proteins, and DNA damage. In this review, we highlight the possible relationship between Hg exposure, epigenetic alterations, and brain tumors., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Many serious inflammatory disorders and nutrient deficiencies induce chronic pain, and anti-inflammatory diets have been applied successfully to modify the inflammatory symptoms causing chronic pain. Numerous scientific data and clinical investigations have demonstrated that long-term inflammation could lead to an inappropriate or exaggerated sensibility to pain. In addition, some Non-steroidal Anti-inflammatory Drugs (NSAID), which directly act on the many enzymes involved in pain and inflammation, including cyclooxygenases, are used to dampen the algesic signal to the central nervous system, reducing the responses of soft C-fibers to pain stimuli. On the other hand, there are a few reports from both health authorities and physicians, reporting that decreased transmission of pain signals can be achieved and improved, depending on the patient's dietary habit. Many nutrients, as well as a suitable level of exercise (resistance training), are the best methods for improving the total mitochondrial capacity in muscle cells, which can lead to a reduction in sensitivity to pain, particularly by lowering the inflammatory signaling to C-fibers. According to the current literature, it could be proposed that chronic pain results from the changed ratio of neuropeptides, hormones, and poor nutritional status, often related to an underlying inflammatory disorder. The current review also evaluates the effective role of nutrition-related interventions on the severity of chronic pain. This review pointed out that nutritional interventions can have a positive effect on pain experience through the indirect inhibitory effect on prostaglandin E2 and attenuation of mitochondrial dysfunction caused by ischemia/reperfusion in skeletal muscle, improving the intracellular antioxidant defense system. These data highlight the need for more nutrition studies where chronic pain is the primary outcome, using accurate interventions. To date, no nutritional recommendation for chronic pain has been officially proposed. Therefore, the goal of this article is to explore pain management and pain modulation, searching for a mode of nutrition efficient in reducing pain., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Background: The incidence and mortality from prostate cancer in most native Asian populations remain low although a gradual increase is observed over the last years., Methods: The statistical analysis of official data on prostate cancer mortality and morbidity was performed for the whole country and for Pavlodar Region., Results: The increase in the incidence of prostate cancer among the population of Kazakhstan is observed, which may be attributed to the introduction of screening program based on serum PSA. Still, the crude incidence rates in Kazakhstan are below world indices. Over the last few years, the decreasing prostate cancer mortality is observed that might be influenced by early diagnosis. The age-standardized incidence rates show that the majority of prostate cancer cases occur in advanced ages (70 years and older)., Conclusion: More research is needed to determine the risk factors for prostate cancer, as well as ethnic and geographical trends for the population of Kazakhstan., Competing Interests: Conflict of interests The authors declare that there is no conflict of interests., (Copyright© Iranian Public Health Association & Tehran University of Medical Sciences.)
