The article covers issues related to the specifics of requirements for the personal protection equipment (PPE) in the field of the nuclear power usage, and briefly describes the history of the PPE evolvement. This work was performed by the employees of the A.I. Burnazyan Federal Medical Biophysical Centre (former Institute of biophysics) which has been creating and enhancing PPE for the personnel of radiation hazardous facilities for more than 60 years. Successes of the PPE developers include the creation of the light respirator “ShB-1 Lepestok” which has been in use since 1950s till now in almost all industries, energy engineering, agriculture, medicine, etc., as well as the development of materials, structures, technology of manufacturing and practical application of reusable, decontaminable, physiologically acceptable insulating suits, fresh-air horse respiratory PPE, decontaminable basic and supplementary overalls and safety footwear for the personnel of nuclear industry and energetics. The system of the personal protection from radiation exposure has been proved during rectification of the consequences of the accident at the Chernobyl NPP. The article examines interim results of major transformation of the personal protection system for the personnel of radiation hazardous facilities in the beginning of 21st century. At the present time efforts on the creation of the PPE standardization and certification system in nuclear industry become regular again. Interstate and national standards regulating requirements and test methods for PPE and materials for its manufacturing, as well as the Technical Regulations “Safety of the personal protection equipment” have been both developed and put in practice. Methods of testing PPE with substances specific to the nuclear industry are being developed, and the Rosatom’s PPE certification system is being formed.

Purpose: The article covers issues related to the providing personal protection for the personnel of radiation hazardous facilities. Specific character of working conditions at the enterprises in the field of atomic energy use is caused by extremely high toxic level of radioactive substances and the fact that there is no human sense organ which can identify dangerous levels of radiation exposure. Establishment of mandatory requirements for manufacturing, identification and verification of personal protection equipment (PPE) in the field of atomic energy use is needed because using of low-quality PPE and PPE not complying with working conditions poses a risk for the health of workers. The article provides results of analysis of the regulatory frameworks, both current and under development, which set the requirements for PPE. Results: Since 2017 Rosatom is executing plans for development of series of industry standards specifying requirements for PPE in the field of atomic energy use and methods of their testing. More than 25 interstate and national standards on PPE were included in the Summary list of standardization documents in the field of atomic energy use. PPE was included in the list of products subject to mandatory certification and having requirements for safety assurance in the field of atomic energy use specified. Industry and national standards establishing requirements for PPE protecting from tritium, radioactive noble gases, radioactive iodine, high-toxic alpha-emitting radionuclides, as well as standards on methods of their testing are planned to be developed soon. Conclusion: The system of standardizing requirements for PPE in the field of atomic energy use created by, together with existing system of certification of PPE in the field of atomic energy use will help to increase effectiveness of personal protection of the personnel at radiation and chemical hazardous facilities in nuclear industry.

Nipah viral encephalitis is one of the fatal re-emerging infections especially in southeast Asia. After its outbreak in Malaysia and Singapore; repeated outbreaks occurred at western part of Bangladesh especially in Faridpur region. Besides, sporadic attacks appear to occur in the country throughout the year. Here two Nipah outbreaks in greater Faridpur district in 2003 and 2004 are described along with brief review on transmission of the virus. Where the history of illness among patients are very much in favour of man to man transmission. Moreover the death of an intern doctor from Nipah encephalitis who was involved in managing such patients in Faridpur Medical College Hospital strongly suggests man to man transmission of this virus. So, aim of this review article to make the health personnel and general people be aware about man to man transmission of virus, so that they can adapt personal protection equipment (PPE) for their protection against this deadly disease.

The purpose of this article is process of analyzing in reference to concert capriccio by C. Munier for mandolin with piano («Bizzarria», op. 201, Spanish сapriccio, op. 276) from the point of view of their genre specificity. Methodology. The research is based on the historical approach, which determines the specifics of the genre of Capriccio in the music of the late 19th and early 20th centuries and in the work of C. Munier; the computational and analytical methods used to identify the peculiarities of the formulation and the performing interpretation of the original concert pianos for mandolins with piano that, according to the genre orientation (according to the composerʼs remarks), are defined as capriccio. Scientific novelty. The creation of Florentine composer,61mandolinist-vertuoso and pedagog C. Munier, which made about 300 compositions, is exponential for represented scientific vector. Concert works by C. Munier for mandolin and piano, created in the capriccio genre, were not yet considered in the art of the outdoors, as the creativity and composer’s style of the famous mandolinist. Conclusions. Thus, appealing to capriccio by С. Munier, which created only two works, embodied in them virtually all the evolutionary stages of the development of genre. In his opus of this genre there are a vocal, inherent in capriccio of the 17th century solo presentation, virtuosity, originality, which were embodied in the works of 17th – 18th centuries and the national color of the 19th century is clearly expressed. Thus, the Spanish capriccio is a kind of «musical encyclopedia» of national dance, which features are characteristic features of bolero, tarantella, habanera, and so forth. The originality of opus number 201 – «Bizzarria», is embodied in the parameters of shaping (expanded cadence of the soloist in the beginning) and emphasized virtuosity, which is realized in a wide register range, a variety of technical elements.

This is a brief review covering the currently available literature on ocular manifestations of COVID-19, andprevention strategies for ophthalmologists. A literature search was carried out of Pubmed, Google Scholar andWHO database of publications on COVID. Keywords used in the search were eye, ocular manifestations,ophthalmology, COVID-19, nCoV-2019, and coronavirus disease. All available articles were reviewed and thosepertinent to the study topic were included. Considering the dearth of information available, ophthalmology journals were also searched separately for relevant articles. Major ocular manifestation of COVID reported in literature is red eye, which usually presents before the onset of respiratory symptoms. Since the eye can be a possible transmission route for SARS-CoV-2, infection control measures should be undertaken by ophthalmologists, including use of personal protection equipment and eye/face covering. A framework for structuring ophthalmological services during the COVID pandemic is also presented in this review.

AbstractBoth in developing and developed countries, farmers often do not protect themselves adequately, especially when applying agrochemicals that are dangerous for their health. The issue is relevant because insufficient protection is between the causes leading to intoxication of farmers and workers who handle these products. The literature suggests that both lack of training and information and low income may explain why, especially in developing countries, protective equipment is under-used. Using data from the Mekong Delta, this study addresses the issue of whether income and household wealth may help explaining the use of incomplete protections against pesticides. The results suggest that income, more than wealth, is a reason why Vietnamese farmers operating in the Mekong Delta fail in using adequate protections. In particular, the data suggest that they may prefer to divert resources to increasing the production of their fields or to buying goods that may be used both as protection and as everyday garments. This behaviour leads to underinvestment in some important protective goods. Possible public interventions to mitigate the problem are suggested; in particular, the promotion of integrated pest management techniques could be useful.

Diagnosis Errors

Advancements in the nuclear industry have led to the development of fully digitized main control rooms (MCRs)—often termed advanced MCRs—for newly built nuclear power plants (NPPs). Diagnosis is a major part of the cognitive activity in NPP MCRs. Advanced MCRs are expected to improve the working environment and reduce human error, especially during the diagnosis of unexpected scenarios. However, with the introduction of new types of tasks and errors by digital MCRs, a new method to analyze the diagnosis errors in these new types of MCRs is required. Task analysis for operator diagnosis in an advanced MCR based on emergency operation was performed to determine the error modes. The cause-based decision tree (CBDT) method—originally developed for analog control rooms—was then revised to a modified CBDT (MCBDT) based on the error mode categorizations. This work examines the possible adoption of the MCBDT method for the evaluation of diagnosis errors in advanced MCRs. We have also provided examples of the application of the proposed method to some common human failure events in emergency operations. The results show that with some modifications of the CBDT method, the human reliability in advanced MCRs can be reasonably estimated.

A nasopharyngeal swab is a sample used for the diagnosis of SARS-CoV-2 infection. Saliva is a sample easier to obtain and the risk of contagion for the professional is lower. This study aimed to evaluate the utility of saliva for the diagnosis of SARS-CoV-2 infection. This prospective study involved 674 patients with suspected SARS-CoV-2 infection. Paired nasopharyngeal and saliva samples were processed by RT-qPCR. Sensitivity, specificity, and kappa coefficient were used to evaluate the results from both samples. We considered the influence of age, symptoms, chronic conditions, and sample processing with lysis buffer. Of the 674 patients, 636 (94.4%) had valid results from both samples. The virus detection in saliva compared to a nasopharyngeal sample (gold standard) was 51.9% (95% CI: 46.3%–57.4%) and increased to 91.6% (95% CI: 86.7%–96.5%) when the cycle threshold (Ct) was ≤ 30. The specificity of the saliva sample was 99.1% (95% CI: 97.0%–99.8%). The concordance between samples was 75% (κ = 0.50; 95% CI: 0.45–0.56). The Ct values were significantly higher in saliva. In conclusion, saliva sample utility is limited for clinical diagnosis, but could be a useful alternative for the detection of SARS-CoV-2 in massive screening studies, when the availability of trained professionals for sampling or personal protection equipment is limited.

Asymptomatic Patients

On March 16, 2020, 198,000 dentists in the United States closed their doors to patients, fueled by concerns that aerosols generated during dental procedures are potential vehicles for transmission of respiratory pathogens through saliva. Our knowledge of these aerosol constituents is sparse and gleaned from case reports and poorly controlled studies. Therefore, we tracked the origins of microbiota in aerosols generated during ultrasonic scaling, implant osteotomy, and restorative procedures by combining reverse transcriptase quantitative polymerase chain reaction (to identify and quantify SARS-CoV-2) and 16S sequencing (to characterize the entire microbiome) with fine-scale enumeration and source tracking. Linear discriminant analysis of Bray-Curtis dissimilarity distances revealed significant class separation between the salivary microbiome and aerosol microbiota deposited on the operator, patient, assistant, or the environment ( P < 0.01, analysis of similarities). We also discovered that 78% of the microbiota in condensate could be traced to the dental irrigant, while saliva contributed to a median of 0% of aerosol microbiota. We also identified low copy numbers of SARS-CoV-2 virus in the saliva of several asymptomatic patients but none in aerosols generated from these patients. Together, the bacterial and viral data encourage us to conclude that when infection control measures are used, such as preoperative mouth rinses and intraoral high-volume evacuation, dental treatment is not a factor in increasing the risk for transmission of SARS-CoV-2 in asymptomatic patients and that standard infection control practices are sufficiently capable of protecting personnel and patients from exposure to potential pathogens. This information is of immediate urgency, not only for safe resumption of dental treatment during the ongoing COVID-19 pandemic, but also to inform evidence-based selection of personal protection equipment and infection control practices at a time when resources are stretched and personal protection equipment needs to be prioritized.
