Textual classifier method applied for medical texts: transfer learning of ResNet on images converted from textual data (Preprint)
Authors: Zhang Hongjian , Ogasawara Katsuhiko
Published: June 2022

BACKGROUND

In medical text processing, the classification methods with high interpretability are primarily dictionary- or rule-based methods, requiring a lot of labor cost in maintenance. However, in recent years, methods of image classification with higher accuracy than that of humans, have been developed.

OBJECTIVE

This research attempts to apply the transfer learning of image classification methods to text classification by converting medical text into images for better performance.

METHODS

This method applies the word embedding method to processed text for feature extraction and then segments it to generate a grayscale image. Then pretrained deep learning method for transfer learning was applied to the grayscale image, and the accuracy of the image classifier was validated by comparing it with that of the deep network transfer learning.

RESULTS

The transfer learning using pretrained ResNet displayed better validation accuracy. The validation accuracies of ResNet-18, -34, and -50 were 85.7%, 93.0%, and 98.9%, respectively; whereas the accuracy of naïve Bayes was 92.4%, and the pretrained model converged faster than the non-pretrained model.

CONCLUSIONS

The feasibility of applying the deep learning method of image processing was demonstrated by converting the text format to the image format.

Authors: Axelrad Jordan , Long Millie , Horst Sara , Afzali Anita , Sapir Tamar , Fajardo Kristina , De Felice Kara , Sandler Robert , Cross Raymond
Published: June 2022

BACKGROUND

Inflammatory bowel diseases (IBD) are chronic inflammatory conditions of the gastrointestinal tract often requiring long-term medical therapy. While adherence to IBD therapies is associated with improved clinical outcomes, overall adherence is poor with reports demonstrating adherence rates ranging from 40% to 80%. Consequently, there is a critical need to develop interventions that monitor adherence in-real time and identify reasons for non-adherence to support clinical teams in initiating effective interventions. Recently, electronic- and virtual-based platforms have been developed to routinely monitor adherence and guide appropriate interventions. A novel remote therapeutic monitoring (RTM) technology, the TapptTM digital health system, has been developed to monitor real-time medication adherence patterns through smart label technologies, capture patient reported outcomes (PROs) and barriers to care, and process patient data through algorithms that trigger personalized digital and human touchpoints between clinical visits. Such digital health solution enables care teams to proactively identify and mitigate nonadherence and worsening clinical outcomes.

OBJECTIVE

We propose a 12-month, multicenter, randomized, controlled trial to assess the effectiveness of TapptTM digital health system on adherence, clinical outcomes, and healthcare utilization among patients diagnosed with IBD starting a new oral or subcutaneous therapy.

METHODS

Specifically, we will (Aim 1) compare adherence as measured by the Medication Possession Ratio (MPR) in participants using the RTM compared to standard of care and (Aim 2) compare clinical outcomes and healthcare utilization in participants using the RTM compared to standard of care.

RESULTS

We anticipate starting recruitment in August 2022.

CONCLUSIONS

Effective medication adherence monitoring and intervention programs need to be cost-efficient, pose little to no burden to the patient, be unobtrusive, record reliable data in real-time, and provide actionable insights to the healthcare team. We anticipate the TapptTM digital health system to improve the MPR, clinical outcomes, and healthcare utilization compared to standard of care.

Diagnostic value of anti-Mullerian hormone in adolescent girls with polycystic ovary syndrome
Authors: Sorokman T.V. , Makarova O.V. , Ostapchuk V.G.
Published: June 2022

Background. Scientific debate continues on the diagnostic criteria for polycystic ovary syndrome in adolescents (PCOS). In adolescents these criteria cause special diagnostic problems due to the fact that the characteristics of normal puberty often coincide with the signs and symptoms of PCOS. There is a need to develop diagnostic criteria for PCOS in adolescents, which could be used in addition to those proposed. A possible additional diagnostic criterion may be the level of anti-Mullerian hormone (AMH). The purpose of the study is to assess the levels of anti-Mullerian hormone in the blood of adolescent girls with polycystic ovary syndrome. Materials and methods. A clinical-anamnestic and laboratory study of 27 adolescent girls (12–18 years) with PCOS was conducted. The comparison group consisted of 25 girls of the same age without gynecological disorders. Determination of AMG was performed in venous serum (Gen II ELISA, Beckman Coulter). Results. The anamnesis of adolescent girls with PCOS was analyzed: intrauterine hypoxia occurred in almost half of adolescents, pathological course of the postnatal period was observed in 25.9%, infectious index was 4.6, hypertensive-hydrocephalic syndrome was found in 23.8%, minimal cerebral dysfunction 28.5%, autonomic disorders— in 47.6%, most of the surveyed girls had average body weight and height, inverted puberty and disharmonious sexual development. The most common symptoms of PCOS in girls were: hypomenstrual syndrome (86.9%), dermopathy (82.6%) and hirsutism (60.8%). The mean AMG in girls with PCOS and in the comparison group was 3.67±1.0 ng/ml (in girls with PCOS 4.8±0.9 and in girls in the comparison group 3.1±0.7 ng/ml, p<0.05). Adolescent girls with form A PCOS had the highest hormone levels— 6.4 [4.8; 6.9] pg/ml, p<0.01, which may indicate a probable diagnostic value of AMG concentration. Conclusions. Adolescent girls with suspected polycystic ovary syndrome should have a complete set of tests to determine the level of anti-Mullerian hormone as an additional marker, especially in the absence of clinical manifestations of hyperandrogenemia.
Associative links between obesity and vitamin D levels as a risk factor for primary hyperparathyroidism
Authors: Goncharova O.A. , Dubovik V.M.
Published: June 2022

Background. To date, the fact and mechanisms of associative links between vitamin D deficiency and primary hyperparathyroidism (PGPT) have been established. In turn, the level of 25(OH)D is influenced by climatic conditions and the presence of obesity (Ob). These set the purpose of the study— to determine the supply of vitamin D in patients with endocrine disorders living in the climate in Ukraine, and to assess the impact of Ob on vitamin D levels and the development of hypercalcemia— signs of PGPT. Materials and methods. BMI, serum calcium (Ca) and vitamin D levels in 145 patients who were in the endocrinology clinic for various endocrine pathologies were studied. The frequency of vitamin insufficiency and vitamin D efficiency, hypercalcemia in groups with and without obesity was analyzed. Results. The proportion of obese in the general group was 33.8%, among men— 28.57%, among women— 35.04% (p < 0.05). The level of Ca in the blood was 2.39±0.02 mmol/l, high Ca level occurred in 16.55%, and Ob— іn 49 (33.49%) patients. Against the background of Ob, the level of Ca was 2.42±0.02, and in non-obese people— 2.38±0.02 (p>0.05). Average level of vitamin D in the blood in the general group was 22.95±0.73mg/ml and was probably lower in individuals with Ob (20.95±1.39 vs. 24.09±0.81mg/ml in groups without Ob, p < 0.05). Distribution of the disease by the degree of provision of vitamin D showed that in a cohort with low security vitamin D and the presence of Ob subgroup with a deficiency of vitamin D (20–29ng/ml) was almost twice as large as the similar subgroup without Ob. As follows, the presence of Ob in patients with endocrine pathology has no probable effect on the incidence of hypercalcemia, but is associated with a probable decrease in the level of vitamin D in the blood with a predominance of subgroups with vitamin D deficiency, while in the group without Ob. Conclusions. In the climatic conditions of Ukraine and the functioning health care system in patients with endocrine pathology, the average level of vitaminD is within its deficiency (22.95±0.73 ng/ml). The presence of obesity in patients with endocrine pathology is associated with a probably lower supply of vitamin D, almost doubling the subgroup with vitamin deficiency (<20ng/ml). The combination of obesity and vitaminD deficiency should be considered as a risk factor for primary hyperparathyroidism in patients with endocrine pathology. Such patients need regular monitoring of blood calcium and parathyroid hormone, as well as medical support for vitamin D.

Authors: Shkala L.V. , Malchevskaya T.I. , Shkala O.V.
Published: June 2022

Background. Elderly patients in the presence of iodine deficiency most often develop functional autonomy of the thyroid gland, accompanied by dysfunction— hyperthyroidism. Due to an excess of thyroid hormones, thyrotoxic cardiomyopathy is formed, in which in most cases there is a syndrome of heart rhythm disturbances— atrial fibrillation. The aim of the study: to find out the algorithm for the differential search for a disease in the presence of hyperthyroidism with severe cardiovascular disorders using the example of a specific elderly patient from real clinical practice. Clinical case. A 61-year-old patient was hospitalized in the intensive care unit for arrhythmogenic shock against the background of an attack of atrial fibrillation. The absence of myocardial infarction, pulmonary embolism, acute adrenal insufficiency was stated. The examination revealed a significant decrease in the level of TSH along with an increase in the levels of thyroid hormones without the phenomena of autoaggression, hyperglycemia, hypocholesterolemia, a tendency to hypoproteinemia, leukopenia. An increase in the thyroid gland, heterogeneity of the structure with hypovascularization, the presence of small multiple nodular formations that require clarification were determined. The patient has atrial fibrillation with variability in blood pressure, impaired repolarization processes, hyperkinetic type of hemodynamics, reflecting cardiomyopathy. In this case, there are all prerequisites for the development of functional autonomy of the thyroid gland: age, endemic region, absence of autoimmune changes, dermopathy, ophthalmopathy. Attention is drawn to the severity of manifestations of thyrotoxic heart with dyshormonal and catabolic syndromes, superimposed on comorbid coronary heart disease, hypertension. Conclusions. Hyperthyroidism in the elderly is manifested primarily by cardiovascular disorders, most often with the presence of an arrhythmia syndrome in the form of atrial fibrillation, which can provoke arrhythmogenic shock. Functional autonomy of the thyroid gland with the formation of thyrotoxic cardiomyopathy has specific clinical course, especially in comorbid conditions, which significantly impairs the quality of life.

Authors: Purba Aisyah Farah Dina , Widyastuti Dyah Titisari
Published: June 2022

The old alun-alun of Jepara is the center of city activity and also used to be the center of street vendors activity. Since 2019, the local government decided to move all the street vendors activity into new alun-alun where is one kilometres away from the previous location. The majority of street vendor stated that the new location is not as comfortable as the previous location. It becomes their reason for illegally returning to trade in the old alun-alun. This research aims to examine how far is the place attachment influence for trading based on the preference of street vendors. The exploration of place attachment was based on three variables, i.e. attachment of person, process, and place. Qualitative research method was conducted through literature review, interview, and field observation. The result shows there is no influence of person and process in street vendors place attachment in trading. Only the physical and social form of place indicates the significant influence in place attachment. The factors of access, space shape and size, amenities, and attractiveness activity contribute to the place attachment in trading that is not found yet in new alun-alun.

The focus of entrepreneurial, strategic and managerial concerns regarding the ensuring of survivability and achievement of successful competitive leverage within, primarily, the turbulent international commercial and business environments, has become concentrated on the development of organisational resilience to withstand the pernicious implications imparted by business discourses by situational complications. The recurrent global financial crises, trigger by divergent and multiplicity of factors, have impinged upon the survivability of business organisations of differential demeanours. The corresponding research endeavour has been oriented towards evaluation of development of constructive response based strategic policies of such SMEs from the organisational resilience angle through determination of the implications of strategic planning and thinking processes which could be employed by such business entities to foment crisis management capacities at the functional and operational domains. Specific research effort has been utilised to demonstrate the characteristics and constituents of the concept of organisational resilience and the influence of strategic management doctrines on such conceptual disciplines. The focal point of the research has been to assessment the empirical evidence regarding achievement of required degrees of organisational resilience, especially by the SMEs. The research undertaking has been cognisant equitably about the inherent deficiencies of SMEs and has involved considerable academic rigour regarding analysis of the prospects of latent opportunities within crisis situations which could be achieved through proficiencies of strategic planning and implementation of the same. The utility of the conducted research has been envisioned as outlining strategic features through which SMEs could ensure organisational resilience-based survivability.
La gestión del agua en América del Norte: contrastes y asimetrías
Authors: Hatch Kuri Gonzalo
Published: June 2022

Algunos especialistas consideran que Norteamérica es una región en la que predomina una noción contradictoria acerca del agua: mientras se padecen estragos derivados de la falta de infraestructura para satisfacer la demanda de agua, al mismo tiempo se registra su abundancia física en los cuerpos superficiales y en el subsuelo; Canadá ilustra el caso. Su extensión territorial favorecida por su vecindad con el Polo Norte, la influencia que recibe de los tres océanos limítrofes y su vegetación abundante, son elementos que favorecen la existencia de enormes glaciares, permafrost, nieves perpetuas y ríos con caudales abundantes en el San Lorenzo, Yukón, Columbia, Milk y los Grandes Lagos, entre otros. En contraste, a México se le considera un país desértico y con problemas de escasez de agua física, sobre todo hasta el límite con la línea del Trópico de Cáncer -casi el 50 % del territorio nacional-. Entre ambos países, a los Estados Unidos de América se le considera un territorio de transición entre la escasez y la abundancia, pero en donde el agua rebasa las determinaciones anteriores para posicionarse como un elemento estratégico para el desarrollo económico y la estabilidad política regional

Authors: Alonso Moctezuma Alejandro , Santos Jaimes Edmundo , Zeta Castañeda Eric , González Alva Patricia , Portilla Robertson Javier
Published: June 2022

Introducción: El tratamiento del queratoquiste, previamente conocido como tumor odontogénico queratoquístico, sigue siendo controversial. El queratoquiste es una lesión odontogénica que probablemente deriva de la lámina dental, de manera frecuente se localiza en la parte posterior del hueso mandibular y, seguramente, representa a la lesión antes denominada quiste primordial. El queratoquiste se considera una lesión benigna de comportamiento biológico agresivo. Una amplia variedad de técnicas se han reportado para su tratamiento, tales como la enucleación, la marsupialización y la resección en bloque, así como la combinación de varios métodos. En general, la resección quirúrgica se considera como la última opción para su tratamiento. Objetivo: Presentar el reporte de un caso de una paciente de 36 años con diagnóstico de queratoquiste odontogénico asociado a un proceso inflamatorio crónico. Material y métodos: El tratamiento de elección fue una descompresión de la lesión usando un tubo tipo Penrose, seguida de irrigación con clorhexidina al 2%. Resultados: Durante el seguimiento se observó una reducción de aproximadamente 80% del tamaño original del quiste. De igual manera, la cavidad aceptaba menos cantidad de irrigación; por último, se realizó una biopsia excisional junto con osteotomía periférica. La biopsia reveló un queratoquiste odontogénico con metaplasia escamosa. Discusión: En el presente caso el tratamiento conservador utilizado resultó exitoso; sin embargo, para este tipo de pacientes el seguimiento a largo plazo es recomendable. Además, la asociación con el síndrome del carcinoma basocelular debe considerarse en pacientes con lesiones extensas o múltiples. Conclusiones: El abordaje quirúrgico inicial dirigido a pacientes con tumores odontogénicos agresivos puede tener efectos importantes en la recuperación de los pacientes afectados y en su calidad de vida. Por lo tanto, un Revista Odontológica Mexicana 2020; 24 (2): 00-133 adecuado plan de tratamiento requiere de la valoración multidisciplinaria de cada caso.

Published: June 2022

Objectives The purpose of this study was to investigate a teacher's experiences with integrated physical education(PE) lessons for different grades at a small-sized elementary school in autoethnography and the teacher’s educational meanings.
Methods For this purpose, data was collected from the memory retrieval, in-depth interviews, and concerned documents of seven third graders, eight fourth graders, the investigator that was in charge in a third grade class and gave integrated PE lessons for different grades, and Kim Sae-ssak in charge of a fourth grade class at Tamheom Elementary School in Miji-gun, C Province during a semester from September, 2020 to January, 2021 to examine the teacher's experiences with integrated PE lessons for different grades and the teacher's educational meanings. Collected data was analyzed in a comprehensive analysis procedure based on practical eclecticism, and research integrity was secured through multi-sided analysis, inter-member review, and peer consultation.
Results The teacher's experiences with integrated PE lessons for different grades were compared to a captain's story exploring an unknown territory. The teacher's experiences were categorized into “preparing for a voyage without a chart,” “striking on a rock upon departure,” “setting up a sail with steering adjusted” and “entering a cruise route.” The educational meanings of the teacher's experiences with integrated PE lessons for different grades were compared to a treasure hunt in a ship's log. The educational meanings were categorized into “expansion of lessons: expanded waters through marine explorations” in that the scope of lessons was expanded, “students' changes: changes to the sailors through an unknown voyage” in that changes were brought to students, and “a teacher's growth: the captain's growth amid waves” in that teacher made growth.
Conclusions Since different grade-integrated PE lessons in small elementary schools have great educational significance for teachers, students, and the class itself, individual efforts and policy support are important.

Second, as a result of analyzing the double mediating effects of self-efficacy and social support, academic exhaustion and social support, self-efficacy and academic exhaustion, in the effect of relationship between academic stress and psychological well-being, there was a partial mediating effect of increasing psychological well-being between the two variables. Third, as a result of analyzing the multiple mediators of self-efficacy, academic exhaustion, and social support in the effect of academic stress on psychological well-being, a sequential multi-mediating functions appeared between the two variables.
Conclusions This study shows the difference from previous studies, that it examines the single, double, and multiple mediation between two variables as an integrated model. It proved the usefulness of increasing psychological well-being through the multi-mediated effect. In particular, it is of great significance in that it revealed the importance of the role of variables, considering complex and diverse aspects, regarding the psychological well-being of adolescent.

We design faster-than-adiabatic state transfers (switching of quantum numbers) in time-dependent coupled-oscillator Hamiltonians. The manipulation to drive the process is found using a two-dimensional invariant recently proposed in S. Simsek and F. Mintert, Quantum 5 (2021) 409, and involves both rotation and transient scaling of the principal axes of the potential in a Cartesian representation. Importantly, this invariant is degenerate except for the subspace spanned by its ground state. Such degeneracy, in general, allows for infidelities of the final states with respect to ideal target eigenstates. However, the value of a single control parameter can be chosen so that the state switching is perfect for arbitrary (not necessarily known) initial eigenstates. Additional 2D linear invariants are used to find easily the parameter values needed and to provide generic expressions for the final states and final energies. In particular we find time-dependent transformations of a two-dimensional harmonic trap for a particle (such as an ion or neutral atom) so that the final trap is rotated with respect to the initial one, and eigenstates of the initial trap are converted into rotated replicas at final time, in some chosen time and rotation angle.

Universal gate sets for quantum computing have been known for decades, yet no universal gate set has been proposed for particle-conserving unitaries, which are the operations of interest in quantum chemistry. In this work, we show that controlled single-excitation gates in the form of Givens rotations are universal for particle-conserving unitaries. Single-excitation gates describe an arbitrary U(2) rotation on the two-qubit subspace spanned by the states |01⟩,|10⟩, while leaving other states unchanged – a transformation that is analogous to a single-qubit rotation on a dual-rail qubit. The proof is constructive, so our result also provides an explicit method for compiling arbitrary particle-conserving unitaries. Additionally, we describe a method for using controlled single-excitation gates to prepare an arbitrary state of a fixed number of particles. We derive analytical gradient formulas for Givens rotations as well as decompositions into single-qubit and CNOT gates. Our results offer a unifying framework for quantum computational chemistry where every algorithm is a unique recipe built from the same universal ingredients: Givens rotations.

Published: June 2022

O objetivo desse trabalho é sugerir uma possível utilização de videogames na co-criação da experiência de viagem, a qual se daria por meio do artifício da gamificação dos atrativos/destinos. Para tanto, foi analisada a franquia de jogos de simulação The Sims 3 – Volta ao mundo, demonstrando que ao serem utilizadas as ferramentas do game, transpondo a experiência virtual à real, atrativos ou destinações poderiam oferecer novas experiências para novas gerações de visitantes. Assim, o jogador poderia, por intermédio do jogo em seu smartphone, experimentar as aventuras na realidade, além de desvendar mistérios e desafios das localidades. O trabalho se baseia na teoria da gamificação, a partir da qual mapeia-se a expansão com vistas a sugerir possibilidades de experiências em atrativos turísticos reais localizados no Egito, fornecendo motivação, interação, narrativas e recompensas ao jogador-turista. Trata-se de uma pesquisa de cunho qualitativo e de objetivos exploratórios e descritivos.

Em Pernambuco, a atividade turística concentra-se no litoral sul do estado, com foco no turismo de sol e mar. Apesar da diversidade cultural pernambucana, na maioria das cidades do interior o turismo ainda está se desenvolvendo. Visando esse potencial da região interiorana e tendo como base a Economia Criativa, buscou-se analisar as possibilidades de desenvolvimento do Turismo Criativo, mais especificamente na cidade de São José do Egito, Sertão do Pajeú (Pernambuco), onde surgiu o projeto audiovisual "Nos Passos da Poesia de São José do Egito". Neste trabalho, apresenta-se uma análise dos discursos das e dos poetas que participaram como entrevistadas, para entender as relações da poesia com a cidade e da cidade com a poesia, e as oportunidades para o desenvolvimento turístico a partir de tais relações.
Economia criativa e turismo em áreas patrimoniais: processos e relacionamentos no Centro Histórico de São Luís, Maranhão

Na contemporaneidade, o interesse pelo patrimônio cultural em suas múltiplas vertentes acentua a implantação de projetos de valorização e revitalização de áreas urbanas e patrimoniais como foco nos processos de inovação, nas indústrias criativas e na articulação entre os distintos atores sociais. O objetivo principal do artigo consiste em promover uma discussão teórica e inicial sobre as ações de fomento aos setores criativos na área patrimonial da cidade de São Luís, bem como tecer reflexões em torno da valorização do centro histórico com o turismo cultural e criativo. A metodologia adotada consistiu numa abordagem qualitativa por meio da pesquisa bibliográfica e documental sobre as ações governamentais de fomento aos setores criativos no centro histórico de São Luís, com vistas a compreender os processos e os relacionamentos relacionados ao empresariamento urbano da área patrimonial e seu agenciamento por meio dos setores criativos em articulação com o turismo cultural. O centro histórico de São Luís apresenta algumas ações convergentes de estímulo aos setores criativos, o que nos leva a afirmar que a área dispõe de atratividade para fortalecer os setores culturais e promover ações compartilhadas de valorização dos sabres e fazeres tradicionais como vias para o desenvolvimento. Ressaltamos a necessidade de captação de negócios comunitários inclusivos nas áreas das culturas populares e da gestão de governança que possa articular os diferentes atores sociais- governos, classe criativa e comunidades em torno de objetivos comuns.
