Vibration analysis of Timoshenko microbeams made of functionally graded materials on a Winkler-Pasternak elastic foundation
Authors: Lien Tran Van , Ha Le Thi
Published: April 2024

In this work, the free vibration analysis of Timoshenko microbeams made of the Functionally Graded Material (FGM) on the Winkler-Paternak elastic foundation based on the Modified Coupled Stress Theory (MCST) is investigated. Material characteristics of the beam vary throughout the thickness according to the power distribution and are estimated through Mori–Tanaka, Hashin-Shtrikman and Voigt homogenization techniques. The Timoshenko microbeam model considering the length scale parameter is applied. The free vibration differential equations of FGM microbeams are established based on the Finite Element Method (FEM) and Kosmatka’s shape functions. The influences of the size-effect, foundation, material, and geometry parameters on the vibration frequency are then analyzed. It is shown that the study can be applied to other FGMs as well as more complex beam structures.

Published: April 2024

The main aim of this paper is to investigate the nonlinear buckling and post-buckling of eccentrically stiffened sandwich functionally graded porous (FGP) cylindrical shells surrounded by elastic foundations in thermal environments and under torsional load by analytical approach in terms of the displacement components. The shells are reinforced by eccentric rings and stringers attached to the inside and material properties of face sheets and stiffeners are assumed to be continuously graded in the thickness direction. The sandwich cylindrical shell is composed of FG porous core and two FG layer coating. Based on the first order shear deformation theory (FSDT) with von Kármán geometrical nonlinearity and smeared stiffeners technique, the governing equations are derived. Using Galerkin method, the closed form to find critical torsional load and post-buckling load-deflection curves are obtained. The effects of porosity parameters, the thickness of the porous core, temperature, stiffener, foundation, material and dimensional parameters are analyzed.

Authors: Simoes Paola Flamia , Silva Thamires Pereira Braga da , Barros Enrique Falceto de , Patrício Karina Pavão , Zandavalli Rafaela Brugalli
Published: April 2024

Objetivo: Calcular a pegada de carbono dos inaladores do tipo gás pressurizado dosimetrado para controle da asma e doença pulmonar obstrutiva crônica (DPOC) dispensados pelo Sistema Único de Saúde (SUS) no Brasil e em Porto Alegre (RS) no ano de 2019. Método: Coleta e análise de dados de dispensação de salbutamol e beclometasona pela rede SUS e Farmácia Popular do Brasil em 2019, obtidas por solicitação ao Ministério da Saúde através da Lei de Acesso à Informação. As dispensações foram multiplicadas pela pegada de carbono proporcional de cada dispositivo utilizando dados já publicados na literatura. Resultados: A prescrição de pMDI no SUS, em 2019, resultou entre 24.889.141 e 60.878.728 toneladas de CO2-eq liberados na atmosfera em todo o Brasil (equivalente a percorrer 23 a 57 milhões de vezes a distância de norte a sul do Brasil com um carro comum a gasolina); e entre 459.830 e 1.151.008 toneladas de CO2-eq na cidade de Porto Alegre (correspondente a percorrer 433mil a 1 milhão de vezes a distância de norte a sul do Brasil com um carro comum a gasolina). Conclusão: No SUS, emite-se enorme quantidade de GEEs a cada ano devido aos dispositivos inalatórios do tipo pMDI. A troca por DPIs ou SMIs nos casos indicados evitaria um grande dano ambiental, e ao mesmo tempo benefício clínico aos pacientes, pois trata-se da primeira escolha atual preconizada pelas diretrizes clínicas para o tratamento de asma e DPOC, promovendo a saúde pública e ao mesmo tempo a saúde planetária.
Acceso abierto en Argentina: una propuesta para el monitoreo de las publicaciones científicas con OpenAlex
Authors: Unzurrunzaga Carolina , Monti Carolina , Zalba Gastón , Alperin Juan Pablo
Published: April 2024

En este estudio se propone una metodología utilizando OpenAlex (OA) para monitorear el acceso abierto (AA) a las publicaciones científicas para el caso de Argentina, país donde rige el mandato de autoarchivo -Ley 26.899 (2013)-. Se conformó una muestra con 167.240 artículos de investigadores del Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) que se analizaron con técnicas estadísticas. Se estimó que OA puede representar entre 85-93% de los autores para todas las disciplinas, excepto Ciencias Sociales y Humanidades, donde solo alcanza al 47%. Se calculó que 41% de los artículos publicados entre 1953-2021 incluidos en la fuente están en AA, porcentaje que sube a 46% al considerar exclusivamente el periodo post ley (2014-2021). En ambos periodos es la vía dorada la que representa mayor proporción. Al comparar periodos iguales post y pre ley, se observó que la tendencia en alza de la vía dorada era preexistente a la legislación y la disponibilidad de artículos cerrados en repositorios aumentó un 5% a lo que se estima en base a tendencias existentes. Se concluye que si bien  la vía verde ha tenido una evolución positiva, ha sido la publicación en revistas doradas lo que ha impulsado más rápidamente el acceso a la producción argentina. Asimismo, que la metodología basada en OA, piloteada aquí por primera vez, es viable para monitorear el AA en Argentina ya que arroja porcentajes similares a otros estudios nacionales e internacionales.

The body politic and the political body in nationalist science: Physical education at Stellenbosch University in the 1930s
Authors: Swart S , Daries A
Published: April 2024

Stellenbosch University (SU) was the first university in Africa to introduce a dedicated physical education certificate course in 1937. In defining the Physical Education Department's raison d'etre, the first head of the department, Dr Ernst Jokl, declared that his main aim was to transform SU into the recognised centre for scientific physical education in South Africa. Beyond this purpose, the institutionalisation of physical education resonated with the institution's Afrikaner-nationalist ethos. At the volksuniversiteit, standardised physical education was intended to contribute to the strengthening of the corporate and individual Afrikaner body. While Jokl played a pivotal role in the establishment of standardised physical education at SU, his tenure was abruptly terminated following controversy surrounding medical examinations of female physical education students. In examining the events that led up to Jokl's swift departure, we explore the origins of physical education at SU and the ways in which the university's institutional culture shaped the trajectory of this nascent discipline. In essence, we argue that Jokl's exit was precipitated by his 'scientific methods' that required students to undress for their medical inspections. While all the students underwent the same examination, the uproar was rooted in the fact that women students were subjected to the inspections. While he argued that his approach was an extension of his scientific endeavours, Jokl transgressed the traditionalist and strongly gendered values of SU and the idealised Afrikaner nation that it sought to both represent and shape.
A Forgotten History: A Historical Overview of Kuilsriver Primary School 1908-2023
Authors: Hamann G
Published: April 2024

This article focuses on the history of Kuilsriver Primary School as it is known today. Whilst this specific school has a very interesting, sometimes difficult, but also a very proud background, not many people in Kuilsriver know and understand its history. This year, 2023, the school is 115 years old. It is really a remarkable achievement for an institution which had to endure extreme hardships through its history. Kuilsriver Primary School, as it is known today, was first called Kuilsrivier Laer Kleurling Skool. This name was given to the school long before legalised apartheid came into being in South Africa. Currently there is no publication on the history of the school. The school opened its doors in January 1908 in Van Riebeeck Road, the main road of Kuilsriver. The placement of the school was a welcome relief to the learners of Brackenfell and Bottelary who had to walk almost six km to the nearest school namely, Sarepta Primary School. After 1948 the country experienced the draconian political system called Apartheid. The area where this school was located was proclaimed as a white area in 1958. The school was therefore removed and relocated to the coloured area of Sarepta. Various attempts were made to disaffirm the existence of the school in the main road. The school also experienced a name change to Jan Bosman Primary School in 1970 but reclaimed the original name in 2011. The old school building structure in the main road of Kuilsriver was demolished in January 1970. The only proof that is left of the school building is a photo of the school.1 The purpose of this article is to put the school's history into perspective in the Kuilsriver area as well as in the broader South African context as Kuilsrivier was part of the early Cape Colony. This article also refers to a similar situation regarding the relocation of a coloured school in Carnarvon in the Northern Cape.
Relative abundance and damage by species in the Lepidoptera borer complex of macadamia nuts in the Barberton area, South Africa

Published: April 2024

Larvae of the nut borer complex, which include Thaumatotibia leucotreta, T. batrachopa, Cryptophlebia peltastica and Ectomyelois ceratoniae, cause extensive economic damage to macadamias in South Africa. Monitoring the changing species composition in this complex over a growing season provides valuable information for managing populations. In this study, pheromone traps were placed in two orchards planted with two different cultivars and used to monitor moth numbers over a 28-week period, while larval numbers and nut damage were monitored weekly over a 21-week period from the onset of flowering. Larvae were identified using a combination of morphology and DNA sequences of ~658 bp of the cytochrome oxidase I (COI) gene. Both larval and moth numbers were dominated by T. leucotreta, followed by T. batrachopa, with respective trap catches of 69% and 27%. Spearman correlations indicated strong linear relationships between nut diameter and numbers of eggs per nut for both the Beaumont and 816 cultivars. Poor correlations were found between weekly moth numbers and the number of eggs per nut. A two- to three-week lag was observed between weekly T. leucotreta trap catches and egg numbers. In contrast, egg numbers correlated strongly with larval infestation levels and the incidence of damaged nuts. Although the numbers of eggs and larvae were higher in Beaumont than cv. 816 nuts, higher incidences of nuts with husk and kernel damage were recorded for cv. 816. This study highlights the importance of monitoring of moth and larval numbers in macadamia orchards and showed that such data could be used to predict pest incidence during the season. This study questions the norm in South Africa, which is that macadamia nut borer (MNB) is usually the most abundant species in the nut borer complex.
Assessment of Individual Psychological Characteristics and Level of Trust Using a Photograph of a Stranger’s Face Before and After Direct Perceptual Interaction
Authors: Strizhova I.V. , Khoze E.G. , Ageeva A.S.
Published: April 2024

The article presents the results of a study of the influence of direct perceptual interaction on the assessment of the individual psychological characteristics of a stranger and the level of trust/distrust in him. The problem of the influence of direct perceptual interaction in conditions of interpersonal perception still remains relevant and requires thorough experimental study. The main assumption of the work is that ideas about a stranger, including a complex dialectical interaction of trust/distrust, will differ significantly before and after direct perceptual interaction. The assessment of individual psychological characteristics was carried out using the “Personal Differential” technique, trust/distrust using the “Perceptive Trust Assessment Test”. The results show that the experience of brief nonverbal face-to-face interaction reduces the number of significant differences in the ratings of naive observers with the ratings of experts. Regardless of the facial morphotype, after the experience of interaction, all sitters are perceived by observers with a bias towards socially desirable individual psychological characteristics, with the exception of the only characteristic (stubborn) in the assessments of the round morphotype. The experience of non-verbal face-to-face interaction has a significant impact on the formation of a more trusting attitude towards a stranger in an outside observer, in contrast to the level of trust formed from a photograph.
Problems and Solutions in the Methodology of Researching the Psychophysiological Effects of Virtual Reality
Authors: Rozanov I.A. , Ivanov A.V. , Abdyukhanov R.H. , Shishenina K.S.
Published: April 2024

The article considers a comprehensive approach to the assessment of psychophysiological effects arising from the perception of virtual reality, based on the well—known principle S → R ("stimulus - response"). The methods used make it possible to evaluate sensorimotor (associated with the development of the "immersion effect"), psychoemotional, cognitive and physiological (related to motor activity and sleep) effects of virtual reality based on both subjective and objective indicators. The above set of techniques was used in experiments simulating the impact of adverse factors of space flight during the testing of special virtual reality technologies used for psychological relaxation (psychological correction). The authors believe that the methodological approach described in the article to the assessment of the psychophysiological effects of virtual reality will be useful in the study of virtual environments used in education and psychology, in the development of simulators of various directions and in other areas of VR application.

Features of Anxiety and Self-Regulation of Mental Activity in a Virtual Environment
Authors: Selivanov V.V. , Pobokin P.A.
Published: April 2024

The problem of anxiety research is the most relevant in Russian psychology. High rates of anxiety lead to a decrease in the efficiency and productivity of people's activities, to difficulties in their socialization and interpersonal communication. An important task of modern science and practice is the timely diagnosis of anxiety of subjects and the development of productive methods and techniques for regulating their behavior. The empirical study is devoted to the study of the peculiarities of self-regulation of mental activity and anxiety of subjects in a virtual environment (students aged 18-23 years). As part of the diagnostic stage, the methodology of Ch.D. Spielberger - Yu.L. Khanin and the questionnaire "Style of self-regulation of behavior" (SSPM) by V.I. Morosanova were used. At the formative stage, students were involved in conducting virtual reality programs from the first person. The reliability of differences in indicators of situational anxiety (p = 0.000711, (p ≤ 0.05)), personal anxiety (p = 0.000609, (p ≤ 0.05)) and behavioral styles on all scales after the subjects' work in a virtual environment was confirmed by the Wilcoxon statistical criterion.
Moral Conformity under Different Forms of Virtual Pressure
Authors: Fedorov A.A. , Rakhmanov A.S.
Published: April 2024

The article presents the results of a study aimed at investigating the influence of two forms of virtual group pressure (depersonalized and personalized) on the manifestation of moral conformity. The experimental material consisted of two types of moral scenarios, where participants were asked to assess the acceptability of certain behaviors. Depersonalized pressure was implemented by informing participants, filling out an online form, about the percentage of people responding in a certain way to the presented moral scenarios. As for the personalized form of pressure, a situation simulating interactions among individuals in instant messaging systems (messengers) was utilized. The study involved 112 participants, with 20 of them forming the pilot study sample and 92 — the main experimental sample. The results indicate that social pressure in the virtual environment leads to the emergence of a conforming response, with personalized pressure in real-time having a stronger influence than passive exposure to depersonalized data. The obtained results are explained within the framework of the biological theory of social pressure, which views conforming behavior as a strategy to optimize metabolic costs. The manifestation of a conforming response for both types of moral scenarios and the absence of gender differences in its expression suggest the potential universality of this strategy.

Published: April 2024

This paper describes the procedure of developing and standardizing the Russian-language online emotional intelligence (EI) test for adolescents aged 10-17 years (EIT-A) in two versions: for younger and older adolescents. The test was developed on the basis of the EI ability model by J. Mayer, P. Salovey, and D. Caruso. Psychometric testing of the test was carried out on 1491 adolescents, students of schools in Moscow and other cities of Russia: 735 respondents aged between 10 and 13 years old (341 boys, 394 girls), mean age - 12.2 years, and 756 respondents aged between 14 and 17 years old (271 boys, 485 girls), mean age - 15.6 years. The analysis showed high reliability of the EIT-A method. The confirmatory factor analysis results indicate the methodology's high structural validity. Its reliability-consistency (Cronbach's Alpha) for the version for the 10-13-year-olds was 0.93, and for the version for the 14-17-year-olds — 0.91. The theoretical validity of the EIT-A method was confirmed: it measures the same construct as the Mayer-Salovey-Caruso Emotional Intelligence Test-Youth Research Version (MSCEIT-YRV), adapted to the Russian-language sample - a test by J. Mayer, P. Salovey, and D. Caruso to assess the EI of adolescents, which has a strong psychometric history. The data obtained provide a basis for using the Russian EIT-A test for research and applied purposes as a reliable methodological tool.
Criminal Appellate Proceedings through the Prism of a Social Project: Synergy of the Society’s Request and Legislative Regulation
Authors: Panokin A. M.
Published: April 2024

Public relations, developing in the process of judicial decisions reviewing in criminal cases on appeal, arise on the basis of criminal procedure law rules with great socio-projective potential, which means activities aimed to create specific images of the future and certain details of programs and plans being developed that often result in a new or modernized social object with an original mechanism and unique means of regulation of public relations. The institution of criminal appellate proceedings has been formed in the process of a long evolution, during which many options for reviewing court decisions were tested and rejected. It also acts as an object of social design, which will help ensure the effectiveness of law enforcement and implementation of the objective of criminal proceedings, enshrined in Article 6 of the Code of Criminal Procedure of the Russian Federation. As the result of designing appeal proceedings in criminal cases, a set of scientifically grounded functional proposals can be developed. They can have a positive impact on the review in the court of appeal, since the latter should be able to satisfy the social interest (need) of interested parties, meaning not the satisfaction of the appeal, but the administration of justice in the full sense of the word.
The Value of Local Self‑Government in the Process of its Interaction with the State: Constitutional and Legal Aspect
Authors: Vasiliev S. A.
Published: April 2024

The local self-government reform in Russia in recent decades has gradually diverted this institution from the essence of its creation, embedding it in the vertical of state power under the image of public power. The 2020 constitutional amendments have only accelerated this process. The paper attempts to substantiate the need to preserve municipal power in the form that it was originally inherent in, being a prototype of the theory of a free community or at least dualism. The paper is based on the theoretical advances of scientists and the author’s insights, as well as on a number of issues of local importance, including land, tax, urban planning and other public relations. The author has attempted to show the need for local self-government at the present time, if the necessary vector of development is given to it by organizational and legal means. The increasingly expanding practice of delegating state powers and the introduction of a single-level system of territorial organization of municipalities plays a negative role in the issue under consideration. In order to overcome problematic trends, it is proposed to implement the existing institutions of municipal law in a new way, which will give positive results and for which there is a real demand from the population. Thus, people are reluctant to participate in various events related to mandatory face-to-face attendance, but actively vote for options for improving public space, do not want to be deputies of rural settlements, but help each other in difficult situations and go out on clean-up days, etc. The subsequent transformation of local self-government should be based on the needs of citizens, not the state.
Arctic Dimensions of Jurisdiction and Raw Material Sovereignty: Problems of National Legal Systems Interaction
Authors: Skachkov N. G.
Published: April 2024

The paper is devoted to the legal regulation of economic activity in the Arctic. It is shown how rulemaking is designed to consolidate the maximum rights to use natural resources. Differentiation of approaches and the use of completely different methods of measuring them are inevitable then. One of them is the interpretation of such a category as sovereignty. It is considered to what extent it meets the constitutive criteria of jurisdiction, the choice in favor of one or another domestic legal system. The relativity of the recognition of conflict-of-laws principles of field availability is noted. The right to develop mineral resources is associated with jurisdictional activities in accordance with acts of national legislation, as well as with the fullness of legal norms  — the obvious universalization of jurisdictions. At the same time, quantitative indicators of sovereignty, if possible, can be established only in relation to the degree of influence of interstate organizations. The legal systems of the Arctic countries then minimize the risks of implementing the decisions taken. In this plane, they draw the desired watershed. Qualitative signs of sovereignty are much more important. This is a visible ability to remain a subject of international relations against the background of current crises, but also an explicit delimitation of jurisdictions first for international law enforcement institutions. Subsequently, it affects national civil rights protection systems.

Transpiring, phytoncidal and gas-absorbing properties of indoor plants and their role in improving the air quality in preschool environments
Authors: Chuenko Natalia F. , Novikova Irina I. , Lobkis Maria A. , Novikov Evgenii A. , Savchenko Oleg A.
Published: April 2024

BACKGROUND: The high incidence of respiratory diseases among children attending preschool educational institutions highlights the need for prevention of respiratory tract infections. With children spending on average up to 10 hours a day in educational settings, the quality of the indoor air environment, including microbial contamination and low relative humidity, poses a risk for respiratory diseases. Placing a selection of plants in organized groups of children can offer a promising and cost-effective approach to promote health and well-being in the modern preschool education system.
AIM: To select indoor plants based on their species and quantity to improve the air quality in organized children’s groups. Moreover, the paper presents recommendations for the installation and maintenance of the plants to create healthier environment for children.
MATERIALS AND METHODS: Among more than 820 species of indoor plants, we have identified the most suitable options for preschool institutions. The selection process involved measuring the dimensions of the plants and the surface area of their leaves using a metric method. To assess the air quality, we conducted air sampling throughout the working week, once per hour, using an aspiration method with a sampling device PU-1B. Simultaneously, we measured the microclimate parameters in all the rooms included in the study. Furthermore, we studied the gas absorption capacity of indoor plants in controlled laboratory conditions within seed chambers with a volume of 200 liters.
RESULTS: In rooms where plants were present, the levels of microorganisms varied. The average relative humidity values in all rooms were consistently below the hygienic standard of 40–60%, as outlined in SanPiN 1.2.3685-21, except for specific times. At 8:00, 9:00, 10:00, and 18:00, the relative humidity ranged from 15–35%. When exposed to a formaldehyde concentration of 3 times the maximum permissible concentration (MPC) Chlorophytum comosum reduced it to the regulated value of 0.01 MPC within 38 hours while the corresponding values for Sansevieria trifasciata and Cyperus alternifolius were 24 and 27 hours, respectively.
CONCLUSION: Introducing a variety of indoor plants into a preschool educational setting can have significant benefits for air quality. The plants possess phytoncidal, transpiring, and gas-absorbing properties that contribute to a reduction in the overall number of microorganisms, a decrease in chemical pollutants, and an increase in air humidity. Our analysis showed that in the presence of indoor plants, the concentration of formaldehyde decreases to a regulated and safe level.
Necessity and possible promising directions for creating artificial choledoch duct (literature review)

Published: April 2024

This review is devoted to the prospect of creating an artificial choledoch duct in case of its intraoperative injuries. Currently, there is no consensus on the optimal tactics of reconstructive surgical interventions, determining indications for the formation of biliodigestive anastomoses and transhepatic drainage of the biliary tract. The quality patients’ life after reconstruction in low mortality rate in this type of surgery decreases due to recurrent cholangitis, which in the future leads to liver abscesses and cirrhosis. The first attempts of prosthetics of the common bile duct were associated with the first use of stents in surgical practice. The second stage in the study of the reconstruction of the common bile duct were attempts to use stents and patches from transplants of subcutaneous veins, urethra, vagina of the rectus abdominis, and small intestine. The third stage in the development of this direction is using stents made with fibers of biodegradable polymer compounds. There several advantages of using biodegradable stents. Firstly, they are completely metabolized in the body and perform a skeleton function. Secondly, it is possible to use multilayer structures by means of cellular technologies that ensure the conformitythis of the model with the structures of the common bile duct. A stent from biodegradable material can be used with radiopaque dye and medications, for example, antibiotics to prevent cholangitis, or drugs supressing enhanced formation of fibrous tissue to prevent strictures.
Radiological methods for diagnosing temporomandibular joint diseases
Authors: Fadeev Roman A. , Ovsiannikov Konstantin A.
Published: April 2024

The article provides a literature review of modern views on the application of radiological methods diagnosing temporomandibular joint diseases. This problem is one of the most current in dentistry. Correct choice of the method of radiological diagnosis of temporomandibular joint diseases is the key to their successful treatment. Computed tomography and magnetic resonance imaging make it possible to assess the severity of the pathological process in more detail than other radiological examination methods, systematize the results obtained and, based on them, distinguish the stages of disease development. However, the most complete assessment of the anatomical and functional state of the temporomandibular joint, including visualization of bone and soft tissue structures, is possible with the comprehensive application of radiological diagnostics methods.

Published: April 2024

In this study, uniaxial compressive strength values of a sand type soil reinforced with polypropylene fiber and silicate-based resin additives with different amounts were investigated. Micro grid fiber (MGF) was tested as a new polypropylene fiber additive in the experiments to compare it with a widely used polypropylene fiber type geosynthetic product used in soil fill improvement applications. According to the findings obtained from the uniaxial compressive strength (unconfined compressive strength) tests, it was determined that the new MGF type fiber usually increased the strength values at higher rates in comparison with the conventional fiber product. As another outcome, it was found that target strength values can be supplied by using less resin amounts for the specimens with fiber additives. It was determined that proper strength improvements can be obtained more economically by the fiber additive use together with the resin, rather than the resin added mixtures without the fiber.

Introducción: las enzimas y marcadores del perfil hepático permiten evaluar la funcionalidad y condición del hígado. Sus elevaciones pueden ser silentes y con cierta prevalencia en muchos adultos. Objetivo: determinar las principales alteraciones en el hepatograma en pacientes que acuden a consulta médica de rutina. Metodología: estudio descriptivo, prospectivo y transversal realizado a partir de resultados de laboratorio de historias clínicas de 364 pacientes de todas las edades y ambos sexos pertenecientes a un policlínico del distrito de Villa el Salvador, Perú desde enero de 2021 a julio de 2022. Las variables fueron: edad, sexo, valores de transaminasa glutámico pirúvica (TGP), transaminasa glutámico oxalacética (TGO), bilirrubina directa, indirecta y total, albúmina, globulinas y fosfatasa alcalina (FA). Resultados: en el promedio total de la muestra, la TGP fue alta (51,05 U/L), así como la bilirrubina total (1,50 mg/dL) y la FA (135,84 U/L). La TGP fue alta en hombres (54,92 U/L) y mujeres (48,86 U/L). La TGO fue normal en mujeres y alta en hombres (48,24 U/L). La bilirrubina indirecta fue alta en hombres (1,33 mg/dL). La FA fue más alta en ambos sexos (143,28 U/L en hombres y 126,38 en mujeres). Según grupo etario, los valores de TGO fueron más altos en el grupo de edad igual o mayor a 40 años (49,99 U/L). Los valores de TGP fueron elevados en ambos sexos (55,96 U/L en hombres y 50,90 U/L en mujeres), así como en la bilirrubina total, la que fue más alta en el grupo de edad igual o mayor a 40 años (2,03 mg/dL). La bilirrubina indirecta, albúmina y FA fueron normales en el grupo de edad igual o menor de 39 años, pero fueron elevadas en el grupo de edad igual o mayor a 40 años (1,13 mg/dL, 5,77 gr/dL y 147,95 U/L, respectivamente). Conclusiones: existen alteraciones en el perfil hepático en pacientes asintomáticos en la muestra estudiada. A pesar de no ser elevaciones significativamente grandes, se recomienda identificar y tratar las posibles causas que pudieran desencadenar dichas elevaciones, así como la realización de más estudios similares a nivel nacional para caracterizar el perfil hepático de nuestra población.

Background: Self-medication is a significant issue in public health, with varying global prevalence. It is one of the major causes of the emergence of antibiotic resistance in India. The study's objective was to identify the pattern, cause, and adverse events of self-medication in Maharashtra's urban and rural areas.
Methods: A cross-sectional survey was conducted using a pre-populated questionnaire; including information on age (18-85 years), non-prescription and prescription medication use. Age, gender, past medical and medication history, social history, and self-medication pattern, frequency, reason, source of information, and adverse events noticed as a result of self-medication are all sociodemographic questions on the questionnaire. A percentage analysis was used to examine the data.
Results: Study states that out of 400 sample, 76% of the individuals self-medicate, with painkillers (49.4%), antacids (23.7%), antibiotics (15.3%), being the most often used drugs for ailments like headache, fever, bodily pain, and acidity. The top most medications taken for self-medication are paracetamol (53.1%), pantoprazole (30.43%), ondansetron (13.62%), and azithromycin (12.46%); 66.07% usage of prescription drugs as self-medication was found. The most frequent causes of self-medication were discovered to be mild illnesses, the easy accessibility of medications, and chemist recommendations, 8% of those surveyed had adverse events, and sources of information were chemists, past prescriptions, family members, and acquaintances.
Conclusions: In Maharashtra, self-medication is a prevalent practice that primarily utilizes over-the-counter (OTC) drugs. As a result, consumers should be made aware of the hazards of antibiotic resistance and other pharmaceuticals.

Authors: K. Saranraj , P. Usha Kiran
Published: April 2024

Background: Medical devices are vital for healthcare diagnosis and treatment but pose inherent risks. Physicians and healthcare professionals play a crucial role in reporting adverse events associated with these devices. Despite this, there is a notable scarcity of literature addressing the knowledge, attitudes, and practices surrounding India's Materiovigilance (Mv) Program. This study aimed to evaluate the knowledge, attitudes, and practices of doctors and postgraduate residents in Andhra Pradesh and Tamil Nadu regarding the Materiovigilance program of India (MvPI).
Methods: It was conducted as an observational, cross-sectional study, a structured self-administered Google Form survey was distributed among medical professionals and citizens of Andhra Pradesh and Tamil Nadu. The survey, comprising 22 questions on knowledge, attitudes, and Mv practices, was disseminated via various social networking sites.
Results: Out of 700 doctors and postgraduate residents surveyed, 496 responded, yielding a response rate of 70.8%. The majority (96.8%) acknowledged the potential for adverse events from medical devices, with 91.1% agreeing on healthcare professionals' responsibility to report such events. Despite experiencing medical device-related adverse events in practice (63.3% of respondents), only a small fraction (12.1%) reported them, although 93.5% expressed willingness to report.
Conclusions: The study underscores a knowledge gap among physicians and residents regarding MvPI in India, highlighting the necessity for educational interventions. To address this gap, MvPI coordinators should organize conferences and seminars aimed at enhancing awareness and reporting practices among healthcare professionals.
