Epidemic Risk

Under present conditions there is a high risk of an epidemic of brucellosis associated with the threat of the spread of the pathogen from many natural sources, as well as artificially as a result of bioterrorist actions. In spite of the vast complex of brucellosis eradication activities around the world, it still remains endemic in many regions of the world. The situation is exacerbated by the ecological spreading of the causative agent of brucellosis on the previously unusual species of natural hosts, accompanied by the emergence of new Brucella species, some of which poses a risk to humans. This paper summarizes the data on the distribution area of human pathogenic Brucella species, structure and level of incidence of brucellosis in different regions of our country and abroad, pathogenicity of representatives of different species and biotypes of Brucella for humans.

The causative agent of furunculosis Aeromonas salmonicida is widely spread around the world and usually affects many cold-water fish (trout), salmon, and less often fish from other families. Currently, there is no scheme for indicating the bacterium of the species A. salmonicida from objects of the external environment, using bacteriophages and accumulation media, which complicates the study of the distribution area of the mentioned microorganism and rapid indication of the pathogen. For this reason, the aim of the study was to develop a scheme for the indication of A. salmonicida bacteria using bacteriophages. To identify field strains of A. salmonicida, we examined 56 samples of water objects in Ulyanovsk and the Ulyanovsk region. Using the environment of accumulation of A. Sl.1 and the differential diagnostic environment A.Sl.2.7 A. salmonicida strains were isolated and typed from 56 samples. We have developed a scheme for the indication of A. salmonicida bacteria based on the modification of the phage titer increase reaction (RSF) using the accumulation medium A.Sl.1. This scheme allows detecting A. salmonicida in the amount of 103m.K./ml within 24 hours. The proposed scheme has the potential to be modified and applied to a whole range of microorganisms, sensitive and specific, allowing to detect bacteria in the substrate in a short time, in the presence of foreign microflora without isolation of pure cultures.

Second Wave

With signs of normalization seemingly in place in the world economy, a number of problems show the possibility of aggravation in the future. The volume of derivatives in American banks grows significantly, high risk instruments are back in place and their use becomes more active, global imbalances increase. All of the above requires thorough approaches when creating mechanisms which can neutralize external shocks for the Russian economy and make it possible to develop in the new post-crisis environment.

Review Study

During ENT practice, we have to examine the nose and perform several nasal procedures in our clinics. Otolaryngologists are at a high risk of exposure to the COVID-19 virus. Nasal endoscopy is a major procedure for the diagnosis of the nasal and paranasal sinus diseases and introducing proper health services for our patients. In addition, the world is living the era of the COVID-19 pandemic, for which we have to protect ourselves, educate our medical staff, and work together against the spread of this severely contagious disease within our communities. The main purpose of this study is to review the protocol of nasal endoscopy in the ENT clinic and enhance the safest way to deal with patients during this pandemic.(1)

Despite the widespread of coronavirus disease-19 (CO­VID-19) infection around the world, there are very scarce reported literature about the care of patients with a known diagnosis of hemoglobin disorders such as sickle cell disease (SCD) or thalassemia and confirmed COVID-19 infection. Thalassemia International Federation issued a position statement to include patients with thalassemia and SCD among the high-risk groups of patients. Here, we present an interesting case of a 42-year-old patient know to have SCD presenting with Vaso-occlusive (VOC) pain episode in the absence of COVID-19 signs and symptoms, who tested positive for COVID-19 infection and had a smooth recovery. This case highlights the importance of screening SCD patients presenting with VOC-related events even in the absence of COVID-19 signs and symptoms.

AbstractOsteoporosis is an important global health problem resulting in fragility fractures. The vertebrae are the commonest site of fracture resulting in extreme illness burden, and having the highest associated mortality. International studies show that vertebral fractures (VF) increase in prevalence with age, similarly in men and women, but differ across different regions of the world. Ireland has one of the highest rates of hip fracture in the world but data on vertebral fractures are limited. In this study we examined the prevalence of VF and associated major risk factors, using a sample of subjects who underwent vertebral fracture assessment (VFA) performed on 2 dual-energy X-ray absorptiometry (DXA) machines. A total of 1296 subjects aged 40 years and older had a valid VFA report and DXA information available, including 254 men and 1042 women. Subjects had a mean age of 70 years, 805 (62%) had prior fractures, mean spine T-score was − 1.4 and mean total hip T-scores was − 1.2, while mean FRAX scores were 15.4% and 4.8% for major osteoporotic fracture and hip fracture, respectively. Although 95 (7%) had a known VF prior to scanning, 283 (22%) patients had at least 1 VF on their scan: 161 had 1, 61 had 2, and 61 had 3 or more. The prevalence of VF increased with age from 11.5% in those aged 40–49 years to > 33% among those aged ≥ 80 years. Both men and women with VF had significantly lower BMD at each measured site, and significantly higher FRAX scores, P < 0.01. These data suggest VF are common in high risk populations, particularly older men and women with low BMD, previous fractures, and at high risk of fracture. Urgent attention is needed to examine effective ways to identify those at risk and to reduce the burden of VF.

Psidium (Myrtaceae) comprises approximately 266 species, distributed in tropical and subtropical regions of the world. Psidium taxa have great ecological, economic, and medicinal relevance due to their essential oils’ chemical diversity and biological potential. This review reports 18 Psidium species growing around the world and the chemical and biological properties of their essential oils. Chemically, 110 oil records are reported with significant variability of volatile constituents, according to their seasonality and collection sites. Monoterpenes and sesquiterpenes with acyclic (C10 and C15), p-menthane, pinane, bisabolane, germacrane, caryophyllane, cadinane, and aromadendrane skeleton-types, were the primary constituents. The essential oils showed various biological activities, including antioxidant, antifungal, antibacterial, phytotoxic, larvicidal, anti-inflammatory, and cytotoxic properties. This review contributes to the Psidium species rational and economic exploration as natural sources to produce new drugs.

The author revises the latest evidence in the literature regarding of organizing medical care for patients with osteoporosis in primary medical care. In the world, there is an increase in the group of older people (60 years and older), therefore, the problem of osteoporosis and osteoporotic fractures becomes very urgent. In Russia, the number of hip fractures will increase by 70% by 2050 compared to 2015. The article provides an overview of studies demonstrating the clinical and cost-effectiveness of population-based screening programs for the identification and subsequent treatment of patients at high risk of fractures, and discusses the issues of secondary prevention of fractures. With the active identification of patients at high risk of fractures and the initiation of antiosteoporotic therapy, a decrease in the incidence of osteoporotic fractures, including hip fractures, is expected.

Character Building

Risk is most often associated with danger and perceived as a harmful aspect of life, as an insidious and unwelcome threat that should be avoided. Risk-taking, however, is sometimes a singular passion, a source of pleasure that becomes a way of life. When freely pursued as a valorised activity, it can be a path to self-fulfilment, an opportunity to confront new situations, and a means for redefining one’s self, testing personal abilities, increasing self-esteem or gaining recognition. Deliberate risk-taking is a form of character building. It accommodates life’s intensities. It is extremely popular in high-risk physical activities and sports and postmodern forms of adventure.

BackgroundDecline in social functioning occurs in individuals who later develop psychosis.AimsTo investigate whether baseline differences in disability are present in those who do and those who do not make a transition to psychosis in a group clinically at high risk and whether disability is a risk factor for transition.MethodProspective multicentre, naturalistic field study with an 18-month follow-up period on 245 help-seeking individuals clinically at high risk. Disability was assessed with the Disability Assessment Schedule of the World Health Organization (WHODAS–II).ResultsAt baseline, the transition group displayed significantly greater difficulties in making new friends (z =−3.40, P = 0.001), maintaining a friendship (z =−3.00, P = 0.003), dealing with people they do not know (z =−2.28, P = 0.023) and joining community activities (z =−2.0, P = 0.05) compared with the non-transition group. In Cox regression, difficulties in getting along with people significantly contributed to the prediction of transition to psychosis in our sample (β = 0.569, s.e. = 0.184, Wald = 9.548, P = 0.002, hazard ratio (HR) = 1.767, 95% CI 1.238–2.550).ConclusionsCertain domains of social disability might contribute to the prediction of psychosis in a sample clinically at high risk.

Delta Virus

Hepatitis delta virus, discovered in 1977, requires the help of hepatitis B virus to replicate in hepatocytes and is an important cause of acute, fulminant, and chronic liver disease in many regions of the world. Because of the helper function of hepatitis delta virus, infection with it occurs either as a coinfection with hepatitis B or as a superinfection of a carrier of hepatitis B surface antigen. Although the mechanisms of transmission are similar to those of hepatitis B virus, the patterns of transmission of delta virus vary widely around the world. In regions of the world in which hepatitis delta virus infection is not endemic, the disease is confined to groups at high risk of acquiring hepatitis B infection and high-risk hepatitis B carriers. Because of the propensity of this viral infection to cause fulminant as well as chronic liver disease, continued incursion of hepatitis delta virus into areas of the world where persistent hepatitis B infection is endemic will have serious implications. Prevention depends on the widespread use of hepatitis B vaccine. This review focuses on the molecular biology and the clinical and epidemiologic features of this important viral infection.
