Background: The aim of this paper was to systematically review the root canal configuration (RCC) and morphology literature of the mandibular second premolar (Mn2P). Methods: Systematic research of five electronic databases was performed to identify published literature concerning the root canal configuration (RCC) of the Mn2P up through July 2020. Studies were selected according to predefined search terms and keywords inclusion criteria: “root canal configuration”, “root canal system”, “root canal morphology”, “mandibular second premolar”, “mandibular premolars”, “morphology” and “anatomy”. Further possible studies were identified by cross-referencing and screening the bibliographies of the selected articles. Results: From 1622 retrieved studies, 44 studies investigating the internal morphology of 17,839 Mn2Ps were included. Most examined Mn2Ps were single-rooted (89.5–100%); two-rooted (0.1–8%) and three-rooted (0.1–3.5%) Mn2Ps at lower frequency. Most frequent RCCs reported were 1–1–1/1 (55.3–99.6%) followed by 1–1–2/2 (0.5–57%) and 2–2–2/2 (0.6–18%). The meta-analysis of seven studies demonstrated that a significantly higher number of RCC type 1–2–1/1 (OR [95%CI] = 2.05 [1.27, 3.33]) and 2–2–2/2 (OR [95%CI] = 2.32 [0.65, 8.63]) were observed in male than in female patients. Conclusions: Different RCC research methods have been reported. Whereas clearing and radiographs were commonly used in the past, CBCT has been prevalent in recent years. A globally high frequency of a 1–1–1/1 RCC in the Mn2P has been reported. Nevertheless, the probability that different, more complicated RCCs can appear in Mn2Ps should not be underestimated and, thus, should be taken into consideration when making decisions during an endodontic treatment.

© 2020 The Authors Background: Since the first report by Perry et al. (1955), most studies affirmed the hypertensive effects of cadmium (Cd) in humans. Nonetheless, conclusions between studies remain inconsistent. Objective: The aim of this study was to reevaluate the evidence for a potential relationship between Cd exposure and altered blood pressure and/or hypertension, focusing on studies published between January 2010 and March 2020. Methods: We reviewed all observational studies from database searches (PubMed and SCOPUS) on Cd exposure and blood pressure or hypertension. We extracted information from studies that provided sufficient data on population characteristics, smoking status, exposure, outcomes, and design. Results: Thirty-eight studies met our inclusion criteria; of those, twenty-nine were cross sectional, three case control, five cohort and one interventional study. Blood or urinary Cd levels were the most commonly used biomarkers. Conclusions: A positive association between blood Cd levels and blood pressure and/or hypertension was identified in numerous studies at different settings. Limited number of representative population-based studies of never-smokers was observed, which may have confounded our conclusions. The association between urinary Cd and blood pressure and/or hypertension remains uncertain due to conflicting results, including inverse relationships with lack of strong mechanistic support. We point to the urgent need for additional longitudinal studies to confirm our findings.

In recent years scientists actively study the influence of domestic violence on psychological status and occurrence of mental disorders in women and girls. Psychological, physical, sexual and other types of violence are distinguished, the consequences of which are studied in many countries under the auspices of WHO. In international studies the serious consequences of domestic violence for women are investigated. It was found out that women develop stressful disorders, depression and dependence on psychoactive substances. Negative influence of domestic violence at girls is expressed in formation of behavioral disorders, violations of sexual development, suicidal trends. At analysis of consequences of domestic violence by WHO was developed the concept of "cycle of violence" and cruelty inside family when in process of long influence of psychological traumatic factors at women and girls aggressive actions occurred so that victim and aggressor changed places. The objective of the study was to analyze the current state of the problem on the basis of the literature data, to study the data on the consequences of domestic violence and cruelty against women and girls, to identify gender-specific violations.

Chronic viral infections including those by hepatitis B (CHB) virus and hepatitis C (CHC) virus have been reported to be comorbidities of chronic spontaneous urticaria (CSU). Here, we performed the first comprehensive review of the peer-reviewed literature (PubMed, Web of Science and Google Scholar) on the prevalence of CHB and CHC in patients with CSU and vice versa. The prevalence of CHB and CHC in CSU does not appear to be increased. Less than 5% and 2% of patients with CSU have markers of CHB and CHC, respectively, according to most of the 32 studies reviewed. Urticarial rash including CSU occurs in ≤3% of patients with CHC as reported by most of 20 studies analysed. Very few patients have been assessed for the effects of antiviral hepatitis treatment on their CSU, and two but not all reportedly showed improvement. Hepatitis B/C infections appear unlikely to be linked to CSU. We suggest that routine screening for these infections in patients with CSU is not relevant or cost-effective and should not be performed unless liver function tests are abnormal, risk factors or symptoms of viral hepatitis are present, or urticarial vasculitis is suspected.

© 2018 Elsevier Inc. Sport-related injury patterns among Para athletes have been described with increasing frequency. This review summarizes musculoskeletal injuries in Para athletes. Seated Para athletes sustain upper extremity injuries more commonly; ambulant Para athletes frequently sustain lower extremity injuries. The upper extremity is the most commonly injured anatomic area in all Para athletes, unlike able-bodied athletes. Advanced age and spinal cord injury may increase the risk of upper extremity injury. Injury data for recreational and youth Para athletes are sparse. Summarizing current injury epidemiology data may help to accelerate the development of injury prevention strategies and lifetime injury models for Para athletes.

Nowadays, the breast-feeding, despite the approved advantages, is not a standard in many communities. The multi-factorial determinants determining its prevalence need to be supported at various levels - from legal and legislative one to views and values of society, conditions of women's labor and also health care system that can develop a favorable environment for breast-feeding. The breast-feeding effects positively on health, economic development and ecology and therefor it is a benefit for children, women and whole society in short-term and long-term perspective. The defense, propaganda and support of breast-feeding need a political will, and financial investments to implement its advantages.

Activation of NLR leads to formation of a multimolecular complex called an inflammasome. This complex is used to drive the processing and release of pro-inflammatory cytokines IL-1β and IL-18. Defects in regulation of an inflammasome activation underlie the development of a series of autoinflammatory diseases such as cryopyrin-associated periodic syndromes, familial Mediterranean fever and others. In this review we discuss forms of pathology associated with mutations and gene polymorphism of inflammasomes NLRP3, NLRP1, NLRС2 and NLRP12.

Aims: Therapeutic inertia, defined as the failure to initiate or intensify therapy in a timely manner according to evidence-based clinical guidelines, is a key reason for uncontrolled hyperglycaemia in patients with type 2 diabetes. The aims of this systematic review were to identify how therapeutic inertia in the management of hyperglycaemia was measured and to assess its extent over the past decade. Materials and Methods: Systematic searches for articles published from January 1, 2004 to August 1, 2016 were conducted in MEDLINE and Embase. Two researchers independently screened all of the titles and abstracts, and the full texts of publications deemed relevant. Data were extracted by a single researcher using a standardized data extraction form. Results: The final selection for the review included 53 articles. Measurements used to assess therapeutic inertia varied across studies, making comparisons difficult. Data from low- to middle-income countries were scarce. In most studies, the median time to treatment intensification after a glycated haemoglobin (HbA1c) measurement above target was more than 1 year (range 0.3 to >7.2 years). Therapeutic inertia increased as the number of antidiabetic drugs rose and decreased with increasing HbA1c levels. Data were mainly available from Western countries. Diversity of inertia measures precluded meta-analysis. Conclusions: Therapeutic inertia in the management of hyperglycaemia in patients with type 2 diabetes is a major concern. This is well documented in Western countries, but corresponding data are urgently needed in low- and middle-income countries, in view of their high prevalence of type 2 diabetes.

In the article, an overview of the information on the method and application technology of SWOT (Strengths, Weaknesses Opportunities, Threats) analysis is presented. The specific characters of the method, the object domain of its application, the task, the methodology are disclosed. An interesting idea is the scheme of the options used to achieve more complete benefit from the method. The strengths and the shortcomings of the SWOT analysis noted by experts in the field of its application are given. Further on, the authors propose an innovative technology for using the SWOT model to develop personalized forecasting, preservation, development, and management of health, based on the provisions of the functional direction of genetics - phenomics. The advantages of technology, the urgency of its application are revealed. The new technology is based on provisions of the development of the theory of the essential adaptation. To ensure the state of health the functioning level of the body's systems must be consistent with the optimality, namely with their response norms, which determine the individual phenotype. In the process of the organism adaptation to the conditions of the external environment, the central nervous system (it's a known fact) and the significant body system (the system with the maximum response norm), determining, respectively, the specific and nonspecific responses of the organism will be released by their activity. In the interaction of body systems, it is important to take the ordering into consideration. Dominant systems can actively involve other systems of the body to the process of adaptation according to the principle of the interaction with them, by strengthening or decreasing their activity. Taking into account the direction of interaction (inhibition, toning), this fact becomes important for understanding the pathogenesis of diseases, their targeted prevention, and treatment. A comprehensive record of the mechanisms of the formation of a specific and nonspecific reaction is used in the interest of identifying and effectively preventing functional disorders in the body. The SWOT analysis technology of personalized forecasting, preservation, development and health management eliminates the main drawbacks of SWOT analysis. On the other hand, the SWOT analysis technology helps to expand the range of application of phenomics, depending on the opportunities and threats of the environment.

Purpose: To analyze and organize the basic techniques to reduce radiation exposure to patients with computed tomography (CT) scan of the head, chest, abdomen and pelvis. Materials and methods: The analysis of publications was carried out on the databases Scopus, Web of Science, MedLine and RINC. Results: The variants of the use of CT of the head, chest, heart, abdominal and pelvic organs in multidisciplinary institutions with different methods of reducing the dose burden on patients have been analyzed. Conclusion: The factors used to reduce the dose for CT can be systematized in three main ways: 1) methods that depend on the attending physician, radiologist and CT staff; 2) parameters of the research protocol; 3) features of CT-devices and software. Considering the factors reducing the radiation dose of patients in support of the need for CT examination, choice of parameters of the CT protocol, CT devices and software allows to significantly reduce the radiation burden on patients (by 10-78%) without compromising the quality of CT images. The development of methods to reduce the dose of irradiation of patients is extremely urgent, especially in screening, multiple CT studies and CT with contrast.

This generalized approach may allow practicing physicians to consider the signs of aging as manifestations of a poly-syndrome disease and facilitate prevention, diagnosis and treatment of common aging-related dysfunctions.

Background

Small intestinal bacterial overgrowth (SIBO) was detected in cirrhosis in many studies. The aim is to perform a systematic review and meta-analysis on the prevalence of SIBO in cirrhosis and on the relationship of SIBO with features of cirrhosis.

Methods

PUBMED search (until 14 January 2018) was performed. Specific search terms were: ‘(cirrhosis) AND (SIBO OR bacterial overgrowth)’. Studies not relating to cirrhosis or SIBO, animal studies, and non-original articles were excluded. A meta-analysis of all studies was performed using a random-effects model.

Results

117 references were identified by the PUBMED search. 3 references were added after handsearching the reference lists of all the articles. 99 references were excluded. 21 studies (included in total 1264 cirrhotics and 306 controls) remained for qualitative analysis and quantitative synthesis. Prevalence of SIBO for cirrhosis was 40.8% (95% CI 34.8–47.1), while the prevalence of SIBO for controls was 10.7% (95% CI 5.7–19.0). OR 6.83 (95% CI 4.16–11.21; p < 0.001). Prevalence of SIBO for decompensated cirrhosis was higher than prevalence of SIBO for compensated cirrhosis (50.5% vs. 31.2%; p < 0.001). SIBO in cirrhosis was associated with ascites (p < 0.001), minimal hepatic encephalopathy (p = 0.001), bacterial translocation (p = 0.026), spontaneous bacterial peritonitis (p = 0.008), prolonged orocecal transit time (p < 0.001), and was not associated with hypocoagulation. Further studies are required to clarify the relationship of SIBO with hyperbilirubinemia, hypoalbuminemia, overt hepatic encephalopathy in past, esophageal varices and systemic inflammation.

Conclusion

Small intestinal bacterial overgrowth is more often detected in cirrhosis than in healthy persons and is associated with some features of cirrhosis.
