  • The clear cell meningioma[CCM] is a rare and recently described as a histologic variant of meningioma. It has been identified and included in new World Health Organization[WHO] classification of the Central Nervous System[CNS] tumors recently. The CCMs are histologically characterized by sheets of spindled to polygonal cells with clear cytoplasm, which is the expression of high glycogen concentration. The CCMs occur in younger patients and usually are located in the spinal canal and posterior fossa. The most interesting aspect of CCM is the high recurrence rate and aggressiveness. Poor outcome has been shown in intracranial and spinal tumor location, but the indicators that predict outcome have not been established. Until now 22 intracranial CCM cases had been reported in English literature and 3 cases in Korean. The authors report two cases of CCM located at cerebral convexity and one at cavernous sinus those were totally removed [Simpson Grade $I{\sim}II$] by subfrontal, frontal and orbitocranial approaches. The clinical, radiological, histopathological, and neurosurgical features of these cases are discussed with the relevant literatures.

  • Automatically detecting mentions of pharmaceutical drugs and chemical substances is key for the subsequent extraction of relations of chemicals with other biomedical entities such as genes, proteins, diseases, adverse reactions or symptoms. The identification of drug mentions is also a prior step for complex event types such as drug dosage recognition, duration of medical treatments or drug repurposing. Formally, this task is known as named entity recognition (NER), meaning automatically identifying mentions of predefined entities of interest in running text. In the domain of medical texts, for chemical entity recognition (CER), techniques based on hand-crafted rules and graph-based models can provide adequate performance. In the recent years, the field of natural language processing has mainly pivoted to deep learning and state-of-the-art results for most tasks involving natural language are usually obtained with artificial neural networks. Competitive resources for drug name recognition in English medical texts are already available and heavily used, while for other languages such as Spanish these tools, although clearly needed were missing. In this work, we adapt an existing neural NER system, NeuroNER, to the particular domain of Spanish clinical case texts, and extend the neural network to be able to take into account additional features apart from the plain text. NeuroNER can be considered a competitive baseline system for Spanish drug and CER promoted by the Spanish national plan for the advancement of language technologies (Plan TL).

  • Purpose: Intensive Care Unit (ICU) is an important field of inpatient treatment, in which critically ill patients have been treated intensively with advanced medical technology. The level of treatment in the intensive care unit and the modernization of related facilities are important indicators of the quality of medical care. At present, when regional public hospitals are expanding frequently, reasonable planning of ICU has become an important part of medical institutions that treat ICU. The purpose of this study is to provide basic data on the net area of each unit, which can be used in ICU building planning. Methods: The investigation and analysis of the ICU were conducted in 12 medical institutions, based on theoretical analysis based on relevant guidelines and literature, and analysis of actual space composition and net area through architectural drawings. Results: This research provides basic data, such as the location relationship with other important departments, regional division, spatial composition, the relationship between main activities and regions, the composition of facilities in the region, and the area and proportions of each region. Implications: It is expected that the results of this article will provide effective reference materials for the reasonable spatial organization and effective operation of the intensive care units of ordinary public hospitals of different sizes in the future.

  • The method of single-cell RNA sequencing has been rapidly developed, and numerous experiments have been conducted over the past decade. Their results allow us to recognize various subpopulations and rare cell states in tissues, tumors, and immune systems that are previously unidentified, and guide us to understand fundamental biological processes that determine cell identity based on single-cell gene expression profiles. However, it is still challenging to understand the principle of comprehensive gene regulation that determines the cell fate only with transcriptome, a consequential output of the gene expression program. To elucidate the mechanisms related to the origin and maintenance of comprehensive single-cell transcriptome, we require a corresponding single-cell epigenome, which is a differentiated information of each cell with an identical genome. This review deals with the current development of single-cell epigenomic library construction methods, including multi-omics tools with crucial factors and additional requirements in the future focusing on DNA methylation, chromatin accessibility, and histone post-translational modifications. The study of cellular differentiation and the disease occurrence at a single-cell level has taken the first step with single-cell transcriptome and is now taking the next step with single-cell epigenome.

  • Purpose: Influenza is the most common seasonal infectious disease that causes permanent social, economic, and medical problems worldwide. Therefore, the most effective way to prevent influenza is through vaccines. The aim of this study is to identify the influence of factors that determine the refusal of influenza vaccine among three subjects groups. Materials and Methods: A survey was conducted amongst the three high-risk groups in 2018-2019 (Moscow, Russia). The survey involved 1,620 parents and pregnant women (group 1), 324 doctors (group 2), and 433 students (group 3). Poor vaccine uptake was observed among respondents in all three groups. Results: According to the survey results, only 22.2% of children and 13.8% of adults were vaccinated against influenza. Group 2 showed increased rates with 36.7% of vaccinated adults and 58.7% of children. The lowest adherence to annual vaccinations was recorded in group 3 (only 17.3%). There is also a negative correlation between adherence to vaccination and smoking (-0.66), unhealthy diet (-0.73), poor oral hygiene (-0.61), and insufficient awareness of the need for influenza vaccine as well (-0.81). Conclusion: Thus, a general lack of vaccination awareness has a fundamental role in forming a negative attitude toward influenza vaccine. It is necessary to conduct research to promote vaccination against influenza to improve vaccine uptake among high-risk groups, particularly students.

  • In planning a genetic association study, it is necessary to determine the number of samples to be collected for the study in order to achieve sufficient power to detect the hypothesized effect. The case-control design is increasingly used for genetic association studies due to the simplicity of its design. We review the methods for the sample size and power calculations in case-control genetic association studies between a marker locus and a disease phenotype.
