Ecological Aspects and Applications of Starch
Authors: Šárka Evžen , Caltová Kristýna , Smrčková Petra , Bleha Roman , Marek Ivo , Fíla Vlastimil , Lhotka Miloslav
Published: April 2023

The article characterizes starch as an important raw material for various technologies. The properties of native starches (e.g. solubility, rheological properties or retrogradation) are not suitable for the given purpose in some cases and are therefore modified – physically, chemically or biochemically. The use of derivatives modified in such a way in food production, as well as for their technical use is indicated. The so-called "clean-label" starches represent a relatively new group, not marked with the E index in food (they are not chemically modified). Their advantage lies in that they respect the environment, not producing chemical by-products. However, their application by manufacturers requires caution to avoid excessive energy consumption and the resulting production costs. In the article, the main attention is paid to the ecological use of native and modified starch – for the production of biogas, bioethanol, biobutanol, as a flocculant, as a part of photocatalytic surfaces, formulation of biodegradable plastics and as an adsorbent. In addition to the literature review, examples of the research in this area at the Department of Carbohydrates and Cereals at the University of Chemistry and Technology are given.

Індивідуальне споживання в Україні в умовах воєнного часу
Authors: Стойка В.О.
Published: April 2023

У статті з’ясовано актуальність дослідження індивідуального споживання, що інтерпретовано як складну систему, яка на основі персоніфікації інтересів споживача, покликана синтезувати відносини між суб’єктами суспільства з метою забезпечення раціональних можливостей щодо відтворення об’єктів споживання. Основним фактором, що визначає рівень індивідуального споживання є дохід індивіда. Рівень та структура індивідуального споживання в Україні є незадовільними, оскільки майже увесь дохід українців спрямовується на придбання лише продовольчих товарів. Така складна ситуація ще більше загострилася після повномасштабного вторгнення Росії, адже суттєво скоротилися грошові доходи населення, збільшився рівень безробіття. Тому з метою вирішення таких проблем й у пошуках стабільності та безпечних місць життєдіяльності відчутними стають міграційні процеси. Одним зі шляхів урегулювання питання щодо індивідуального споживання може стати розробка ефективного механізму його державного регулювання.

Систематизовано різні наукові точки зору щодо трактування категорій «електронна комерція», «електронна торгівля», «цифрова торгівля». Визначено характерні риси електронної торгівлі. Виділено сегменти торгівлі: В2В, В2С, С2В, С2С та їх частки у продажів у електронній торгівлі. Пандемія та воєнні дії в Україні завдали величезних збитків промисловим підприємствам, але представники електронної торгівлі отримали додаткові вигоди від ситуації. В умовах економічної нестабільності розкрився потенціал галузі та виник великий інтерес з боку потенційних інвесторів. Згідно з прогнозами, ринок електронної торгівлі в Україні продовжить зростати навіть після того, як воєнні дії закінчаться, а нормальне життя відновиться як і раніше.

Thyroid Detection
Authors: Sajid Prof. Mohammad
Published: April 2023

Thyroid Gland is a vascular gland and one of the most important organs of the human body. This gland secretes two hormones which help in controlling the metabolism of the body. The two types of thyroid disorders are Hyperthyroidism and Hypothyroidism. When this disorder occurs in the body they release certain types of hormones into the body which imbalances body’s metabolism. Thyroid related blood test is used to detect this disease but it is often blurred and noise will be present. Data cleansing methods were used to make the data primitive enough for the analytics to show the risk of patient’s getting this disease. Machine Learning plays a very deciding role in the disease prediction. Machine Learning algorithms SVM-Support Vector Machine, KNN-K-nearest neighbours, Random Forest, K-Means Algorithms are used to predict the patient’s risk of getting thyroid disease.

Churn Prediction in Banking Sector
Authors: Kamble Pratik Vinayak , Nair Ajesh , Saini Tina , Patil Girish Vasant
Published: April 2023

The membership of a banking system depends on the interest provided for the account , charges on the transactions and the services provided on the account. Now-a- days, many banks provide competitive services which give customers options to choose from. This might lead to customer dissatisfaction and result in the deactivation of the membership also known as churn. Churn is 'when a client cancels a membership to a company they have been using. In this project we will try to predict the churn from the previous databases of the banking systems and study it using data visualization. In current days, the customers are getting more attracted towards the quality of service (QoS) provided by the company. As a result, customer churn and engagement has become one of the main problems for most of the banks. In this project, we have used a voting approach of SVM and Random Forest to find the most successful and accurate way to predict customer churning or retention. Key Words: Churn, banking system, retention, deactivation, SVM, Random Forest.

SECURING DSR PROTOCOL DEFENDING AGAINST SYBIL ATTACK IN MANET
Authors: Vijayalakshmi D.M
Published: April 2023

Mobile ad hoc networks (MANETs) are infrastructure-free networks in which nodes are free to move in any direction. These networks use specific routing protocols that can create a path between nodes that are not within transmission range of each other. Because MANETs are easy to configure, they are mostly used in areas where infrastructure is not available, such as military and rescue operations, etc. Due to the open approach, MANETs are always vulnerable to external and internal attacks such as Denial of Service (DoS), Flooding, Worms hole, Black hole, Gray hole Sinkholes etc. There is no central point of administration. In this project, we focus on the Sybil attack. An SYBIL attack is an individual type of association layer attack in a specially selected mobile network. In this attack, a fake hub is introduced that has a direct path to reach the target. So it collects the entire packet from the source and drops it. Nowadays, it is very difficult to secure the network against such attacks. The Dynamic Source Routing (DSR) algorithm uses caching concepts to store all newly created routing paths in mobile ad hoc networks. Route caching aggressively uses DSR. With source routing, it is possible to cache each overhead path without causing loops. Forwarding nodes cache the source path from a packet and forward it for future use. The destination also meets all the requirements. Thus, the source learns many alternative paths to the destination, which are stored in the cache. Here, we propose a novel approach to prevent Sybil attacks in DSR based on route caching. In this approach, once a Sybil node is detected in the MANET during path construction, we pass the Sybil node id to the DSR path function. In this function, routes are ready to be added to the route cache; however, adding each route to the route cache is decided by parsing those routes for the presence of a Sybil node id. This process uses only the normal time of the caching process. In this project, we propose a cache-based Sybil attack prevention algorithm for DSR routing protocols in MANET. Simulations in NS-2 show that our proposed mechanism greatly reduces the packet drop rate with a very low false positive rate. Keywords: Mobile Ad Hoc networks (MANETs), Sybil Attack, Denial Of Service (DOS), Dynamic Source Routing (DSR), Route Caching, Packet Drop Rate, NS-2.
A Survey on Sign Language Recognition with Video Chat

Published: April 2023

The use of sign language is a crucial tool for improving communi- cation between hearing-impaired people and the general public. SLR (Sign Language Recognition) systems in the past have been sophisticated and challenging to train. However, in this research, we provide a novel method that makes use of SSD MobileNet V2 FPNLite 320x320 pre-trained models and object recognition based on TensorFlow's object detection. By enabling the identification and detection of a set of images, this method streamlines the train- ing process. The suggested system will be trained and evaluated using 10 to 15 different American Sign Language symbols. A fun- damental social skill used to exchange information is communica- tion. It is frequently used to express oneself and to fulfill funda- mental human needs including the desire for protection, safety, and connection. Several stages, diverse methods, and distinct conse- quences are used in this procedure. It typically refers to a two-way exchange of information in the local vicinity of touch. Information flows far more easily when people are speaking the same language than when they are speaking languages that are from distinct lan- guage families. In order to facilitate video chat communication be- tween signers and non-signers, our proposed sign language recog- nition system is specifically created. Each peer can see and hear the other during a video conversation thanks to their individual cameras and microphones. Nevertheless, using our method, a spe- cific peer can also view the indicators that the other peer on the other end of the video chat exhibits or copies. Our system employs object detection to recognize and track the signer's hand motions in real-time in order to accomplish this. The technology then over- lays a graphic of the detected sign onto the non-video signer's feed. This overlay is positioned so that it does not obstruct the view of the signer by the non-signer and is not obtrusive. By using contem- porary technology, our suggested solution is made to enable distant and two-way communication between signers and non-signers. With the help of our system, video chat communication is im- proved, allowing signers and non-signers to communicate and in- teract more effectively.

FIRE IMAGE DETECTION USING CNN
Authors:   Department of Information Technology, Vasantdada Patil Pratishthan’s College  of Engineering and Visual Arts, Mumbai, India, Avhad Prof.Vedika
Published: April 2023

Fire detection is a critical task in ensuring the safety of human lives and property. In recent years, deep learning techniques, such as Convolutional Neural Networks (CNNs), have shown promising results in fire detection due to their ability to automatically learn relevant features from images. In this project, we propose a real-time fire detection system using CNNs to detect fires in images or video streams. The proposed system consists of a CNN-based architecture that includes multiple convolutional layers for feature extraction, activation functions for introducing non-linearity, pooling layers for spatial dimension reduction, and fully connected layers for global pattern learning. The architecture is trained on a labelled dataset of fire and non-fire images or videos using optimization algorithms to minimize the loss function. To achieve real-time fire detection, the trained CNN model is integrated into a fire detection system that can process images or video streams in real-time. The system captures images or video frames from a live feed, pre-processes the data, and passes it through the CNN model for fire detection. The system can generate alerts or notifications in real-time when fire is detected, allowing for prompt response and mitigation measures. The performance of the proposed fire detection system is evaluated using metrics such as accuracy, precision, recall, and F1-score. The system is tested on different datasets and under various conditions to assess its accuracy, robustness, and real-time processing capabilities. The results of this project demonstrate the effectiveness of CNNs for real-time fire detection and highlight the potential of the proposed system for enhancing fire safety in various applications, including surveillance systems, smart buildings, and industrial settings. The developed system can be used as an early warning tool for fire detection, enabling timely response and mitigation, and helping to prevent or minimize the damage caused by fires. Keywords: Fire
A study of MOSFET Device for The characterization of ID-VG and ID-VD Curves
Authors: Rashid Taha , RASHEED MOHAMMED , Sarhan Muhammad , Jaber Ahmed , Aldaraji Mustafa , Saidani Tarek , Anwar Abdul-jabbar Anwar
Published: April 2023

In this paper, the MOSFET device structure has been simulated using an open-source simulator and the characterization of the ID-VG and ID-VD curves has been studied. The n-channel MOSFET device structure for three distinct generations has been simulated using the provided parameters, getting the corresponding I-V curves and observing their surface charge - Vg properties using the online simulator Nanohub. Based on the reported electrical characteristics, we may deduce that the Vth values decrease when the MOSFET device is scaled down. The current Id when Vg is zero is substantially higher in the third generation of the device than in the first and second generations, indicating that there is greater leakage current. Consequently, this is the punch through effect because current flows regardless of the gate voltage (i.e. even gate voltage is zero). Therefore, the device's third generation is poorly developed. In terms of performance, we can infer that the first iteration of the design is superior than the second and third generations. Therefore, substrate doping may be enhanced further for the second and third generation, while oxide thickness can be lowered further for improved performance. As the concentration of doping increases, however, we must additionally consider the influence of ionization.
Impact of Urea-Intercalated-Biochar on N-Release in Soil and Humified Soil Organic Matter
Authors: Olubisi O. J. , Dick D. P. , Ojo A. O. , Bottezini L. , Adesanwo O. O.
Published: April 2023

This research investigated the impact of urea-intercalated-biochar (ICB) on nitrogen release as well as on humified soil organic matter (SOM) distribution in highly weathered soil. Incubation studies were performed with a typical dystrophic red Ultisol and with 10 treatments: soil without amendment (control, CON), soil with three doses of biochar (BC75, BC145, and BC 290), and soil with ICB doses (ICB75, ICB145 and ICB 290). BC and ICB were characterized by 13C Nuclear Magnetic Resonance 13C-NMR CP/MAS spectroscopy and elemental analyses. N-extractable forms were periodically determined by Kjeldahl method and humic substances (HS) distribution was analyzed on the 28th day after incubation begins (DAI). Intercalation of urea in BC increased sample N content from 2.7 to 22 %, whereas that of C decreased from 40 % to 28 %. As a consequence, C: N decreased from 14.9 to 1.3. The 13C NMR spectra of BC and ICB were similar but relative abundance of major organic functional groups differs, for example, ICB presented a greater proportion of C=O groups due to the carbonyl group of urea and a greater proportion of N/O alkyl C, O-alkyl C, and anomeric C groups due to the addition of starch. There was a significant increase in the concentration of extractable N-NH4+ by addition of urea from the onset of incubation down late period and a significant difference (P > 0.05) was obtained between the ICB and BC over time. This could be as a result of the less accessible form of N in the biochar materials due to the pyrolysis process. There was no evidence of extractable N-NO3- ion until 14 DAI, significant difference in N-NH4+ concentrations at 28 DAI between the ICB and control was observed over time and the highest value recorded from ICB treated pots at 145 and 290 kg N ha-1.

Foliar application of nano urea is a good option of nitrogen or a balanced dose of nitrogen to increase the yield of black gram. For that, this study was conducted to evaluate the performance of black gram (Vigna mungo L.) under two forms of nitrogen at the Bangladesh Institute of Nuclear Agriculture (BINA) sub-station experimental field, Chapainawabganj during September to December 2022. Black gram variety Binamash-2 and 3 treatments, viz. Control (no fertilizer) (T1), Farmers practice (recommended fertilizer application as basal dose and top dressing during active growth) (T2) and Nano urea (2-4 ml of nano urea (4 % N) in one litre of water and sprayed on crop leaves at its active growth stages) (T3) were used under randomized block design. Yield and yield contributing characters were significantly affected by different forms of nitrogen (urea). The highest grain yield was obtained with T3 which was 1587.33 kg per hectare whereas T1 had given the lowest yield (983.33 kg per hectare). It was obvious that grain yield of black gram can be increased substantially with the judicious application of nano urea as foliar spray during active growth stages.
Chapter III - Sor Juana and the Infuence of the Coimbra Jesuits
Authors: Aspe Virginia
Published: April 2023

In this chapter I present two points that should be taken into account when reading the poem Primero Sueño by Sor Juana Inés de la Cruz. First off, I have sought the philosophical-poetic justifications for the text, as well as its possible interpretations, in order to demonstrate that any unilateral focus on its content and meanings must be shunned. Primero Sueño has to be read as it is, an open and polysemic philosophical poem that incorporates the cultural influences of a recently-born Novohispanic Criollismo in a novel fashion. Secondly, my investigation proposes a new reading of the poem, focusing on the connection and relevance of 17th century Jesuit theology to the author’s lines.

O milho é conhecido como a cultura de maior expressão para ensilagem no Brasil, em função das suas características qualitativas e quantitativas, além da boa aceitação por bovinos, bubalinos, caprinos e ovinos, tanto para a produção de leite, quanto para ganhos de peso satisfatórios em animais de corte. Para uma produção adequada de silagem é fundamental a recomendação de cultivares com melhor qualidade nutricional e potencial produtivo, adaptadas para a região de cultivo. Objetivou-se com este trabalho avaliar parâmetros produtivos e agronômicos de diferentes cultivares de milho destinados à produção de silagem. O estudo foi composto pelas cultivares AS 1757, AG 9025, BM 3051, BM 3063 E BM 3066. Foram mensuradas as seguintes características agronômicas: altura das plantas (m), quantidade de espigas por planta, peso do colmo (g), peso da espiga (g), peso da palha (g) e peso da folha (g), peso total por planta (g)  e produtividade em massa fresca por área. O delineamento experimental utilizado foi em blocos ao acaso, com 5 tratamentos e 4 repetições. Os dados foram submetidos ao teste de médias e análise variância pelo Teste de Tukey a 5 %. Todos os parâmetros testados apresentaram diferenças estatísticas entre as diferentes cultivares. Considerando altura média os tratamentos BM 3063 (3,45 m), BM 3066 (3,32m) e BM 3051 (3,26m) apresentaram médias superiores em relação aos demais cultivares. O peso seco da espiga foi maior nos híbridos AS1757, AG9025 e BM 3051. Considerando o peso da folha, as cultivares testadas não apresentaram diferenças significativas entre si. A maior produtividade de silagem foi obtida pela cultivar BM 3063, com 130.215,00 kg/ha, sendo estatisticamente superior ao híbrido BM 3066 com 95.273,00 kg/ha.  Conclui-se que entre as cultivares de milho avaliadas, as mais indicadas para a produção de silagem na região de Fazenda Rio Grande (PR), considerando sua boa produtividade e composição morfológica foram BM 3063 PRO2 e AG 9025 PRO3.

The popularity of organic food has been increasing over the years as people have become more concerned about the health, safety and quality of the food they and their family consumes. This study aims to investigate consumer perceptions towards organic food and why people purchase it. The research was conducted through a survey of a sample of consumers in various age groups and demographics. The results indicate that consumers perceive organic food tobe healthier, safer, and more environmentally friendly than conventionally produced food. Consumers also believe that organic farming methods are more sustainable and ethical. Consumers prefer to purchase organic food from certified organic sources, and they trust government regulation to ensure the authenticity of organic food products. The study suggests that increasing awareness and education about organic food and its production can help bridge the knowledge gap and dispel misconceptions about organic food. Furthermore, improving the availability and affordability of organic food productscan increase consumer access and help grow the market for organic food. The study highlights the importance of effective communication, education, and regulation in building trust and confidence in organic food products.

Published: April 2023

Las certificaciones ambientales son condiciones que permiten realizar obras de construcción, implementando así estrategias que aseguren procesos mas limpios para la mejora o conservación del medio ambiente. A través de un trabajo analítico y comparativo, este trabajo identificará las similitudes y diferencias entre los sistemas descubiertos y así poder determinar si se corresponden con la realidad actual del Ecuador, un país que cuenta con grandes diferencias socioculturales en cada una de las cuatro regiones geográficas. En el caso de nuestro país, Ecuador… como en casi todos los países en vías de desarrollo, la construcción de obras civiles tiene un gran impacto en el medio ambiente. Desde pequeñas casas hasta grandes proyectos, alteran el medio ambiente con consecuencias para todos.  El tiempo relativamente corto que lleva implementar las normas para garantizar que la construcción sea respetuosa con el medio ambiente indica que todas las etapas de un proyecto, vivienda, edificio, carretera, hidráulica o de otro tipo, se ven desde una perspectiva ambiental racional. Los resultados muestran que las certificaciones ambientales emitidos por el Ministerio del Ambiente ecuatoriano son Green Point y carbono neutral y muestran que un gran porcentaje de las empresas ecuatorianas aún no cuentan con estos certificados, siendo esta una razón por la cual aún no se cuenta con ellos. tener las habilidades que se aplican a estas certificaciones. Se dice que las certificaciones ambientales ayudan a las empresas a aumentar su competitividad a través del beneficio económico y aumentar los ingresos, mejorar la imagen de la empresa, reducir la generación de residuos y atraer nuevos clientes.
МЕДИКО-СОЦИАЛЬНЫЕ АСПЕКТЫ ПРОБЛЕМЫ ХИРУРГИЧЕСКОГО ЛЕЧЕНИЯ МОРБИДНОГО ОЖИРЕНИЯ (Обзор литературы)
Authors: Ботиров Акрам , Расулов Муроджон
Published: April 2023

В данном литературном обзоре авторы отмечают, что во всем мире наметилась отчетливая тенденция к неуклонному росту ожирения, и в том числе морбидного ожирения. Данной проблемы посвящены ряд исследований, где изучаются вопросы этиопатогенеза, методов консервативного и хирургического лечения. Однако, не смотря на достигнутые успехи, в 90-95% случаев консервативная терапия безуспешна, а при хирургическом лечении в 60% случаев отмечаются осложнения в отдаленные сроки, которые требуют повторного оперативного лечения в 25% случаев. Данное обстоятельство, на наш взгляд, связано с отсутствием конкретизированных лечебно-диагностических алгоритмов, а также не достаточным уделением внимания сочетанной патологии, требующих симультанной операции, что вызывает настоятельную необходимость проведения дальнейших исследований.

Blockchain-based solutions for clinical trial data management: a systematic review
Authors: Zhang Wei
Published: April 2023

Blockchain technology can reduce the need for intermediaries in various types of transactions by providing a decentralized and secure ledger that can be accessed and updated by all parties involved in the transaction. Clinical trials are essential for bringing new drugs and therapies to market, but the current clinical research process is often marred by inefficiencies, data inaccuracies, and a lack of transparency. The implementation of blockchain technology in clinical trials has the potential to address these challenges by providing a secure and transparent platform for data management. By leveraging the power of blockchain, healthcare providers can improve the integrity and accuracy of clinical trial data, enhance trust in the clinical research process, and ultimately improve patient outcomes. In this article, we propose the use of blockchain technology in clinical trials and explore its potential benefits for the healthcare. The implementation of a blockchain-based data management system for clinical trials holds significant potential to address several challenges associated with the current clinical research process. By improving the integrity and security of medical data, enhancing trust, and easing regulatory burden, such a system can promote the efficient and effective conduct of clinical trials. The adoption of a blockchain-based solution for clinical trial data management has the potential to optimize costs, contributing to the sustainability of healthcare services. It also provides a model for future research and development of blockchain-based solutions in the field of clinical research.
Understanding Blockchain Technology: How It Works and What It Can Do
Authors: Gupta Barnali
Published: April 2023

Blockchain is a chain of blocks that are connected together and are continuously growing by storing transactions on the blocks. This platform uses a decentralized approach that allows the information to be distributed and that each piece of distributed information or commonly known as data have shared ownership. Blockchains holds batches of transactions that are hashed thus providing them security and they are managed by peer-to-peer networks. Blockchain, an information administration method, has the potential to encourage responsibility and openness. In a blockchain, each user of the computer network can access the same copy of the transaction ledger. The blockchain technology has the potential to handle various security attacks as it can eliminate the need of the centralized authority to perform various operations. In the blockchain technology, a number of users participate in transaction verification and validation.
O que está acontecendo? O que os trending topics podem nos dizer a respeito de ações políticas coletivamente orquestradas
Authors:   Fluminense Federal University, Chagas Viktor
Published: April 2023

Este artigo se propõe a compreender as dinâmicas concernentes a ações políticas, executadas por meio de hashtags no Twitter. Seu principal objetivo é responder se o acompanhamento dos trending topics pode ajudar a identificar momentos de tensão política aguda. Com base em uma análise de fluxos de ranqueamento, a hipótese principal levantada por esta investigação é de que, como tendências de uma opinião pública conectada, as trends podem operar como um termômetro sobre o clima de opinião nas redes. Além disso, é possível notar, através do uso de hashtags como marcadores de apoio e desarrimo, o emprego de táticas de astroturfing para alcançar visibilidade e repercussão nas mídias sociais. O estudo empreendeu uma coleta sistemática das principais trends no Brasil, entre janeiro e julho de 2019, a fim de avaliar estratégias relacionadas à capacidade concorrencial desses grupos.

Resumen

Introducción: El decúbito prono (DP) fue la estrategia más utilizada en paciente con COVID-19 e hipoxemia refractaria. Nuestro objetivo fue describir las características clínicas y evolución de los pacientes con Covid-19 grave que requirieron este procedimiento. Evaluar la relación entre factores de riesgo y mortalidad.

Materiales y método: Estudio descriptivo retrospectivo observacional. Se incluyeron los pacientes mayores de 18 años con COVID-19 bajo asistencia respiratoria mecánica (ARM) que requirieron DP. Se efectuó seguimiento durante 28 días. Se registraron las complicaciones asociadas al DP. Se analizaron factores asociados a la mortalidad utilizando regresión de Cox.

Resultados: Se realizó DP en 28 pacientes. La edad promedio fue de 52.43 años y una mediana de Score de Charlson de 1 [0.00, 2.00]. La mediana de días de ARM fue de 17.00 [RIQ 13.00, 23.00] y un 28,6% logró ser extubado. La mediana de días en UTI fue de 19.50 [RIQ 14.00, 23.50] con una mortalidad del 53,6%. El 35,7% necesito 2 ciclos de DP con una duración predominante de 24-36 hs. El 89,4% tuvo lesiones de UPP. Los que fallecieron tuvieron menos días de UTI (16 vs 28; p=0,006) y solo uno de ellos había logrado ser extubado (1 vs 7, p= 0.011). No se encontraron factores asociados a la mortalidad en la regresión de Cox.

Conclusión: La población estudiada resultó predominantemente masculina y de edad promedio cercana a la quinta década de vida, con una mortalidad aproximada al 50%. No se encontró relación estadísticamente significativa entre factores de riesgo y mortalidad.

Published: April 2023

Los pacientes con COVID-19 tienen un amplio espectro de presentación clínica y las tasas de mortalidad en los casos graves son relativamente altas. La identificación temprana de los factores de riesgo que se relacionan con la gravedad de la enfermedad es de vital importancia. 

 

Con el objetivo de correlacionar los síntomas iniciales de COVID-19 con la gravedad de la enfermedad, se realizó el presente estudio de cohorte transversal retrospectivo y observacional de 413 pacientes con diagnóstico de COVID-19 entre enero y marzo 2021. De todos los síntomas iniciales estudiados, la disnea (p <001), fiebre (p 0.001), tos (p 0.002), odinofagia (p 0.01), cefalea (p 0.01) y síntomas gastrointestinales (p 0.03), se asociaron con el desarrollo de una enfermedad grave. Las comorbilidades que se asociaron con peor pronóstico fueron: hipertensión arterial (p <0.001), obesidad (p <0.001), EPOC (p <0.001), ex tabaquismo (p <0.001), diabetes (p 0.01), enfermedad cardiovascular previa (p 0.03), y enfermedad oncológica activa (p 0.04). 

 

En conclusión, los pacientes con diagnóstico de COVID-19, cuya manifestación inicial es disnea, fiebre, tos, odinofagia, cefalea y síntomas gastrointestinales, deben ser monitoreados de cerca para prevenir el deterioro de la enfermedad.

Introducción: es probable que SARS-CoV-2 favorezca el paso de infección a enfermedad tuberculosa. Si bien la información es limitada, hay avances en la comprensión de la interacción COVID-19 y Tuberculosis. Nuevas investigaciones arrojaron similitudes inesperadas en la patogenia y evolución de la coinfección. Linfopenia prolongada, hiperinflamación, lesión del tejido pulmonar y desequilibrio en los subconjuntos de células T CD4+ asociados con COVID-19, podrían propagar la infección por M. tuberculosis y progresión de la enfermedad.
Casos clínicos: presentamos tres pacientes jóvenes, sin comorbilidades, con factores de riesgo para Infección Tuberculosa Latente, diagnosticados de Tuberculosis pulmonar posterior cursado COVID-19 leve, de tratamiento sintomático (no corticoideo).
Discusión: estos casos plantean el probable impacto del SARS-CoV-2 en el paso de Infección Tuberculosa Latente a enfermedad, excluyendo la ya demostrada influencia de los corticoides y formas graves de COVID-19. Existe cada vez más evidencia que refuerza esta idea.
