Abstract
Background: The purpose of this study was to investigate the prevalence of osteosarcopenia in the over 60-year-old community and to evaluate whether osteosarcopenia is associated with disability, frailty and depression.Methods: This study was performed using the baseline data of Namgaram-2, among the 1010 surveyed subjects, 885 study subjects who were 60 years or older and had all necessary tests performed were selected. The Kaigo-Yobo checklist (frailty), World Health Organization Disability Assessment Schedule (WHODAS) and Geriatric Depression Scale-Short Form-Korean (GDSSF-K) were used. The Asian Working Group for Sarcopenia (AWGS 2019) were applied in this study. Osteopenia was measured using data from dual energy X-ray absorptiometry (DEXA) and osteopenia was diagnosed when the T-score was less than -1.0.The study subjects were divided into four groups: the normal group, in which both sarcopenia and osteopenia were undiagnosed, osteopenia only, sarcopenia only and the osteosarcopenia group, which was diagnosed with both sarcopenia and osteopenia. Results: Of the 885 subjects over 60 years old evaluated, the normal group comprised 34.0%, the only osteopenia group 33.7%, the only sarcopenia group 13.1%, and the osteosarcopenia group 19.2%. WHODAS (17.5, 95% CI: 14.8-20.1), Kaigo-Yobo (3.0, 95% CI: 2.6-3.4), and GDSSF mean score (4.6, 95% CI: 3.9-5.4) were statistically significantly higher in the osteosarcopenia group compared the other groups. Partial eta squared (ηp2) of WHODAS (0.199) and Kaigo-Yobo (0.148) values ​​according to Osteosarcopenia were large, and GDSSF (0.096) was medium.Conclusions: Osteosarcopenia is a relatively common disease group in the older adults community that may cause deterioration of health outcomes. Therefore, when evaluating osteopenia or sarcopenia in the older adults, management of those in both disease groups should occur together.

Abstract
A smart grid (SG) is an advanced power grid system deployed in a cloud center and smart meters (at the consumer end) that provides higher reliability, better data protection, improved power efficiency, automatic monitoring, and effective management of power consumption. However, an SG also poses certain challenges that need to be addressed. For example, data provided by a smart meter are time-sensitive and cannot handle high latency in an SG. Moreover, a smart meter depends on memory, energy, and other factors. Besides, the security between a cloud center and a smart meter is a critical issue that needs to be resolved. Edge computing, an extension of cloud computing deployed in an edge network between a cloud center and the end devices, is an efficient solution to the aforementioned issues. Therefore, in this study, we propose a secure mutual authentication protocol based on edge computing for use in an SG.

Abstract
Background: Dental appearance affects facial beauty, social interaction and psychological well-being particularly among adolescents. The aim of the current study was to determine factors affecting adolescent dental self-confidence and satisfaction with dental appearance in Saudi Arabia.Methods: A cross-sectional study was conducted in the Eastern Province of Saudi Arabia among 3500 students attending intermediate and high schools. Data was collected from 2637 students using the translated Arabic version of the psychosocial impact of dental esthetics questionnaire (PIDAQ) in addition to questions about smile esthetics satisfaction and demographic variables including; gender, age, school grade, and parental level of education. Statistical analysis was performed by using logistic regression to assess the effect of demographical variables on PIDAQ and its domains at 5% significance level. Results: About 80% of the participants were satisfied or somewhat satisfied with their smiles. Tooth alignment and tooth color were the most cited reasons for adolescents’ dissatisfaction about their smile, 34% and 33% respectively. Females and participants’ fathers’ university education figured in a statistically significant way regarding higher PIDAQ and aesthetic concerns. Females were 70%, and those with fathers’ university education were 22% more likely to have a negative psychological impact. Females expressed aesthetic concerns nearly two times more than males. Participants whose fathers possessed university education had an aesthetic concern 1.25 times more compared to those whose fathers had no school or limited school education. Females and those with mothers who had university education were less likely to have positive dental self-confidence. Conclusions: Most adolescents exhibited satisfaction with their own smiles. Smile dissatisfaction in the remaining participants was related to teeth alignment, color and shape. Females were more concerned with dental esthetics and smile satisfaction than males. Females and participants whose fathers had a university education exhibited higher psychosocial impact than males and those with or without school education. However, males showed greater self-con­fidence in their dental aesthetics.

Abstract
The ongoing Arctic warming has been pronounced in winter and has been associated with an increase in downward longwave radiation. While previous studies have demonstrated that poleward moisture flux into the Arctic strengthens downward longwave radiation, less attention has been given to the impact of the accompanying increase in snowfall. Here, utilizing state-of-the art sea ice models, we show that typical winter snowfall anomalies of 1.0 cm, accompanied by positive downward longwave radiation anomalies of ~5 W m-2 can decrease sea ice thickness by around 5 cm in the following spring over the Eurasian Seas. This basin-wide ice thinning is followed by a shrinking of summer ice extent in extreme cases. In the winter of 2016–17, anomalously strong warm/moist air transport combined with ~2.5 cm increase in snowfall decreased spring ice thickness by ~10 cm and decreased the following summer sea ice extent by 5–30%. Projected future reductions in the thickness of Arctic sea ice and snow will amplify the impact of anomalous winter snowfall events on winter sea ice growth and seasonal sea ice thickness.

The objective of the study: to compare the diagnostic value of intracutaneous tests with tuberculin and diaskintest for detection of tuberculosis in cattle.Subjects and methods. In this study, PPD tuberculin for mammals was used, it was made from M. bovis strain AN-5, manufactured by BIOK, and Diaskintest (recombinant tuberculous allergen, solution forintracutaneous administration) manufactured by ZAO FF Lecco, series 030307.Laboratory animals (guinea pigs, rabbits, chickens) and farm animals (pigs and cattle) were used in the study.Results. It has been established on laboratory animals that diaskintest does not cause any adverse events. When assessing sows sensitized with M. avium, it was found that the intracutaneous administration of PPD tuberculin to mammals resulted in up to 8.5% of positive reactions, while diaskintest was negative in all of them. Among cattle sensitized to non-tuberculous mycobacteria, intracutaneous administration of tuberculin for mammals revealed up to 4.6% of positive reactions, and diaskintest – up to 0.6%. In the farm with the unfavorable TB situation where animals infected with M. bovis were previously detected, when examining 177 cows, tuberculin test was positive in 102 (57.6%) of them, and diaskintest in 88 (49.7%). Diaskintest can be used for differential diagnosis of tuberculosis and sensitization by non-tuberculous mycobacteria in pigs and cattle.

The objective: to determine the state and prospects of TB control services including the period during the COVID-19 pandemic.Materials. Data from Federal Statistic Surveillance Forms no. 4, 8, 14, 14-DS, 30, 33, 47, and 61 were analyzed. The number of those died is presented as per the data of Rosstat.Research methods: epidemiological and statistical analysis, expert assessment, and content analysis of publications and regulations.Results. In Russia in the second decade of the XXI century, there was a significant improvement of tuberculosis situation. From 2010 to 2019, the reduction of the rates was the following: incidence – from 77.2 to 41.2 per 100,000 population (by 46.6%); prevalence – from 177.5 to 86.4 per 100,000 population (by 51.3%); mortality – from 15.4 to 5.1 per 100,000 population (3-fold reduction).In recent years, one can anticipate the stabilization of HIV situation. Over 10 years (2006-2015), the average growth rate of indicators was the following: incidence – by 9.8%, prevalence at the end of the year – by 9.4%, mortality – by 26.6%. In 2016-2019, HIV incidence became stable (2019 – 54.6 per 100,000 population). In 2019, for the first time HIV mortality decreased by 2.1% and reached 13.7 per 100,000 population. The number of lethal TB/HIV co-infection cases is going down. People at the age of 15-34 fall ill (2019 – 37.6%) and die (23.6%) less often versus all new cases and those who died of HIV infection. Russia has the highest coverage of the population with HIV tests (28.5%).Epidemics of tuberculosis and coronavirus infection are developing in the opposite directions. High rates of COVID-19 are observed in regions with low tuberculosis rates, therefore the COVID-19 pandemic will not result in the increase of tuberculosis incidence in the population that is predominantly not infected with tuberculosis. Conversely, in regions with a high level of tuberculosis infection in the population, the number of coronavirus cases is significantly lower.In Russia, in the near future COVID-19 will not contribute to the increase in incidence and mortality of tuberculosis and HIV infection. The negative effects of the pandemic are partially offset by a sharp reduction in contacts, an increase in lung computed tomography, regular supply of anti-tuberculosis and antiretroviral drugs purchased by the state budgets of different levels, improved patients’ adherence to treatment, and the expansion of hospital-replacing technologies in specialized medical organizations.Facilities, resources and personnel of medical TB control services make it possible to expand their functions to fulfill the goals and objectives of the RF Healthcare Development Strategy for the period up to 2025 for socially significant infectious diseases that pose a biological threat to the population (tuberculosis, HIV infections, and parenteral viral hepatitis).

Gastroesophageal reflux disease (GERD) is a widespread disease. Despite the fact that different approaches to the treatment and prevention of recurrence of this disease have been developed, the number of patients with GERD, including refractory form of GERD, is only increasing. To date, well studied and described the possible links of the pathogenesis of this disease, which predetermine certain approaches to the treatment of various variants of GERD. Effective drug therapy of GERD includes the appointment of proton pump inhibitors (PPI). However, doctors are often faced with the problem of ineffective use of PPI in patients with GERD or with the so-called refractory form of GERD. The reasons for the ineffectiveness of therapy of PPI can be associated not only with the pathogenetic features of GERD and therapy, but also with the patient himself. Daily pH monitoring allows to determine the cause of the ineffectiveness of the treatment of PPI if the patient complies with all prescriptions. With ineffective acid suppression in the stomach, it is necessary to increase the dose of PPI or replace it. It is important to prescribe both effective and safe means of correcting the symptoms of GERD, and also take into account the possibility of long-term maintenance of remission when using them. These requirements are met by PPI, created in the form of enantiomers, having an improved pharmacokinetic profile. An example of this differentiated approach is dexlansoprazole, a law-converting monoisomer of lansoprazole with double release technology and the ability to maintain the antisecretory effect for a long time, which appeared relatively recently on the Russian pharmaceutical market. The use of this drug is presented in a clinical case.

Introduction. At present, global prevalence of celiac disease attracts increasingly greater attention of researchers. The study of its extraintestinal manifestations is a crucial task for early and timely diagnosis of the disease, as well as the identification of new risk groups. To date, there are only isolated publications concerning the study of celiac disease incidence in patients with acne. This topic is of particular interest since systemic retinoids with a hepatotoxic effect and antibiotics significantly affecting the intestinal microflora are the first-line drugs in the treatment of moderate and severe acne. Undoubtedly, these side effects influence on the course of acne in celiac patients. So, to prevent the complications of the treatment, it is necessary to search, develop and introduce into practice safe combinations, including drugs having a protective effect both for the intestinal microflora and for the liver. It is known that psyllium (Plantago ovata seed shells/Ispaghula husks) have similar effects.Objective. To study the effect of psyllium on the tolerability and effectiveness of systemic therapy with isotretinoin and doxycycline in patients with moderate acne with celiac disease. Material and methods. We examined 65 patients with celiac disease suffering from moderate acne, who were randomized into two groups – group 1 (taking an antibiotic – doxycycline) and group 2 (taking a systemic retinoid – isotretinoin), then each group was divided into two subgroups A and B, depending on the prebiotic intake (powder of oval plantain seeds shells Plantago ovata Forssk (psyllium). The patients were followed up for 8 and 24 weeks, respectively. All patients received adjuvant topical therapy. In each group, a medical check-up was done before treatment, 2 months after the onset and then after the treatment completion.Conclusion. Patients in both subgroups who received psyllium in addition to antibiotics and systemic retinoids treatment showed better results after treatment in terms of skin condition, overall health and quality of life.

Published: January 2021

An analytical review of domestic and foreign literature on the problem of osteoporosis was performed, and the principles of the approach to diagnosis and treatment of this disease are described.The probability of vertebral fracture should be assumed if there is a history of growth loss of 4 cm or more, the appearance of kyphosis in patients who received long-term therapy with glucocorticoids, with bone mineral density (BMD) less than 2.5 points In the treatment of patients with osteoporosis at the initial stage there is a tendency to limit oneself to non-drug measures, advising to change lifestyle and diet, to increase intake of vitamin D and calcium with food, to optimize physical activity. However, the main place in the prevention and treatment of osteoporosis in postmenopausal women is occupied by medication therapy, which can reduce the risk of fractures by 70%: bisphosphonates, drugs derived from parathyroid hormone, denosumab and selective estrogen receptor modulators. It is advisable to start therapy with oral bisphosphonates in most cases. They are powerful inhibitors of bone resorption and act by reducing the activity of osteoclasts and increasing their apoptosis. In 2020, the patent protection period of the main original bisphosphonates expired and generics of Russian production appeared: Rezoviva (ibandronic acid 3 mg for intravenous injection once every 3 months) and Osteostatix (zoledronic acid 5 mg 100 ml solution for intravenous drip once a year). After 3–5 years of bisphosphonate treatment, treatment should be reconsidered. The risk of recurrent fractures should be reassessed after the injury occurs. The risk of new fractures increases in patients who stop treatment. Study results have recommended ibandronate as a first-line drug in women with postmenopausal osteoporosis. Studies comparing intermittent intravenous ibandronate administration with daily oral treatment in women with postmenopausal osteoporosis allowed to recommend intravenous ibandronate at a dose of 3 mg every 3 months as the preferred therapy.

Introduction. Radiculopathy is one of the causes of neuropathic pain. Among the causes of back pain, lumbar radiculopathy ranks second after non-specific musculoskeletal pain. Patients with radiculopathy have a marked decrease in the quality of life, a tendency to disability, which causes a large amount of diagnostic and therapeutic measures and associated economic losses. There is no unified view on the pathogenesis of radiculopathy, and the pain syndrome includes neuropathic and nociceptive components. The proposed treatment regimens for radiculopathy differ and are of a recommendatory nature.The purpose of the retrospective observational study was to study the effectiveness of the drug Neurobion® in the complex therapy of radiculopathy.Materials and methods. The study of outpatient records of 120 patients aged 25–65 years, suffering from lumbosacral radiculopathy was performed. The patients were divided into 2 groups and received basic therapy, which included NSAIDs, simple analgesics, muscle relaxants, and anticonvulsants. Patients of group 1 additionally received the drug Neurobion®.Results and discussion. Faster regression of clinical manifestations was observed in group 1 patients. The results of treatment in group 1 patients were higher both in terms of subjective feelings and objective criteria. The presence of two medicinal forms of Neurobion® allows a personalized approach to the patient’s therapyConclusions. The use of the drug Neurobion® is pathogenetically justified in the treatment of radiculopathy, provides earlier positive dynamics of subjective feelings of patients and objective indicators, improves the quality of life, leads to shorter treatment periods, reducing economic costs. The effectiveness and good tolerability of the drug Neurobion® allow us to recommend it for inclusion in the complex therapy of radiculopathy.

Diabetic polyneuropathy is the most common neurological complication of diabetes mellitus (DM) and may affect about half of all patients with diabetes. Timely diagnosis and treatment of DPN can prevent such serious complications as limb numbness, severe pain during the day and night, foot ulceration and suppuration, amputation of the foot or toes, disability and even death. The combined approach to the treatment of DPN is the most effective and includes glycemic control, diet, optimal hypoglycemic therapy, management of cardiovascular diseases, educational conversations with patients, psychological support in the form of consultations with a psychologist or psychotherapy, and sufficient pathogenetic and symptomatic drug therapy of DPN. A clinical case of managing a patient with T2DM, DPN and cardiovascular diseases is described in detail. The interdisciplinary approach was used to treat the patient, which included the use of drug and non-drug therapies. The drug therapy of diabetes was adjusted, and medications to treat cardiovascular diseases were prescribed. Pathogenetic therapy of DPN remains a highly controversial issue. Among the drugs that affect the pathogenetic mechanisms of DPN, careful consideration was given to B vitamins and alpha lipoic acid. In the presented clinical case report, the patient was prescribed a combination drug containing vitamins B1, B6 and B12 as a pathogenetic therapy of DPN. A high priority in the treatment of DM and DPN is placed on raising awareness among patients about the causes and prognosis of the disease. Most patients with diabetes and DPN have psychological problems, symptoms of anxiety and depression about the disease, catastrophization of existing symptoms, poor adherence to medication due to feelings of despair and thoughts of the disease as incurable. In view of above factors, psychological methods appear as effective in the treatment of patients with diabetes and DPN. The cognitive behavioural therapy was used in the described clinical case as a psychological method. The use of CBT improved the patient’s emotional state, increased his adherence to medications and lifestyle recommendations. A positive effect in the form of decreased severity of neuropathic and autonomic symptoms of DPN was observed in as little as 10 days after treatment. At follow-up Week 12, the patient’s condition continued to improve and his work capacity increased.
