Authors:   , Cayo Bulnes Rogger Antonio , Chang Pardo Isabel Romina
Published: July 2024

La rinoplastia es una de las cirugías plásticas más populares a nivel mundial. En el año 2020 ocupó el cuarto lugar en frecuencia según la International Society of Aesthetic Plastic Surgery (ISAPS). Asimismo, los aspectos psicológicos se encuentran intrínsecamente asociados a la decisión de realizarse un procedimiento quirúrgico estético. Además, hay evidencia de que puede mejorar la autoestima y confianza. Sin embargo, existe evidencia de mayor prevalencia de algunos trastornos de salud mental, especialmente Trastorno dismórfico corporal (TDC). Revisiones previas se han centrado en la asociación entre TDC y rinoplastia. No obstante, existen otros trastornos mentales como depresión, ansiedad, trastornos de personalidad, entre otros que pueden también estar asociados a rinoplastia. Objetivo: Valorar la presencia de trastornos de salud mental en los pacientes que buscan una rinoplastia en comparación con grupos controles que no la busquen. Método: Se realizó una búsqueda en las bases de datos de PubMed, Scopus, Embase, Web of Science y Ovid MEDLINE para obtener los artículos de estudio que contengan información cuantificable. Las medidas de asociación empleadas fueron odds ratio y diferencia de medias, según el tipo de variable dependiente evaluada en cada estudio. Cuando se encontraron estudios que evaluaban la misma variable dependiente como dicotómica y numérica, se transformaron los odds ratio a diferencia de medias estandarizadas empleando el método de Chin. De esta manera se realizó un metaanálisis integrado por cada variable dependiente. Se evaluó el riesgo de sesgo de cada artículo incluido empleando la escala de Newcastle Ottawa para estudios de casos y controles, cohortes y una versión adaptada para transversales, según corresponda. Resultados: Al analizar los datos obtenidos sobre los trastornos de salud mental en adultos que buscan una rinoplastia y los del grupo control en los diferentes artículos. Se emplearon 15 artículos. Se realizaron cuatro hallazgos estadísticamente significativos en los Trastorno dismórfico corporal con 5 artículos (DME= 1.50, IC=0.34, 2.67 , n=694), Trastorno de ansiedad con 8 artículos (DME=0.46, IC=0.27, 0.61 , n=739), Trastorno de personalidad narcisista con 2 artículos (OR =9.36, IC=1.63, 53.68 , n=160) y Trastorno de personalidad obsesivo-compulsivo con 3 artículos (OR =2.72, IC=1.06, 7.00 , n=276). Conclusión: El Trastorno dismórfico corporal, el trastorno de ansiedad, trastorno de la personalidad narcisista y trastorno de la personalidad obsesivo-compulsivo se asociaron a la búsqueda de rinoplastia. Sin embargo, se necesitan más estudios para comprender mejor esta relación.
Factores asociados al diagnóstico de tuberculosis en niños y adolescentes evaluados por tos crónica en un hospital pediátrico en los años 2017 a 2019

Published: July 2024

Factores asociados al diagnóstico de tuberculosis en niños y adolescentes evaluados por tos crónica en un hospital pediátrico en los años 2017 a 2019 Introducción: La tos crónica es aquella que tiene una duración mayor a 4 semanas y se calcula que representa alrededor del 5% a 10% de las consultas en neumología pediátrica. En el 2018, la OMS reportó más de un millón de casos de tuberculosis infantil, con una mortalidad de 14%. Sin embargo, esta enfermedad no está incluída en la actualidad en los algoritmos de tos crónica, y su diagnóstico se dificulta por la tos paucibacilar presentada en niños y la variabilidad en la presentación clínica. Justificación: En la actualidad, no existe una guía para el diagnóstico diferencial de la tos crónica en el Perú que haya sido adaptada al diagnóstico clínico de tuberculosis en el país, a pesar de que esta enfermedad representa un alto costo y uso de servicios médicos. Asimismo, un diagnóstico precoz de la tuberculosis se asocia a una menor incidencia de complicaciones a largo plazo. Materiales y Métodos: Se realizó un estudio de tipo transversal analítico utilizando las historias clínicas recolectadas como muestreo no probabilístico por casos consecutivos tipo censo con motivo de consulta de tos por más de 4 semanas en el año 2019. Se calculó la razón de prevalencia según la regresión de Poisson. Resultados: Se analizó a 220 pacientes con una mediana de tos de 6 semanas (IQR 4-12). La mediana de la edad fue de 3.75 años (RIQ: 1.92 a 6.29) y 73 (60.8%) pacientes fueron varones. El antecedente de contacto epidemiológico tuvo una RP de 3.08 (IC95% 1.23-8.38, p=0.016). La pérdida de peso tuvo un RP de 3.06 (IC 95% 1.12-8.38, p = 0.03) y presentar una prueba de PPD positiva aumentaba en 2.71 veces (IC 95% 1.67-24.03, p=0.007) la probabilidad de tener tuberculosis en la población estudiada. Conclusiones: La baja de peso, el contacto epidemiológico y el PPD positivo fueron factores asociados al diagnóstico Sin embargo, estudios a mayor escala y con poblaciones diversas son necesarios para el desarrollo de una guía estandarizada.

Pemahaman Hadis tentang Adab: Minum Sambil Berdiri (Sebuah Kajian Hadis Tematik)
Authors: Pramesta Bayu , Ananda Yassinta , Ahmadsyah Muhtadin
Published: July 2024

Minum sambil berdiri dianggap sebagai sesuatu yang buruk dan kurang beradab di masyarakat. Hal ini berlandaskan hadis dalam shahih Muslim yang menjelaskan bahwa Rasulullah melarang minum sambil berdiri. Bahkan, di hadis lain dijelaskan bahwa orang yang minum sambil berdiri maka ia telah minum bersama Syaitan. Namun demikian, Rasulullah juga pernah minum dalam keadaan berdiri, di mana itu terjadi ketika Rasulullah sedang melakukan haji wada’ tahun ke 10 Hijriah. Ketika itu Rasulullah diberi minum air Zam-zam oleh Ibn Abbas dan beliau meminumnya sambil berdiri. Artikel ini bertujuan untuk mengetahui pemahaman hadis-hadis tentang minum sambil berdiri. Dengan menggunakan metode kajian hadis tematik yang bersumberkan kitab al-Kutub At-Tisáh, artikel ini menyimpulkan bahwa hadis tentang minum sambil berdiri secara tematik memiliki perbedaan pendapat di antara para ulama. Ada yang berpendapat haram, ada yang membolehkan secara mutlak, ada yang membolehkan secara bersyarat, ada yang berpendapat hadis yang melarang sudah mansukh karena hadis yang membolehkan datang belakangan, yaitu ketika haji Wada’. Dengan demikian, hampir semua pendapat mengatakan minum sambil duduk lebih baik. Hal ini karena dari segi Kesehatan memiliki dampak yang signifikan. Ada beberapa efek buruk bila minum sambil berdiri, yakni di samping tidak dapat memberikan kesegaran bagi tubuh secara optimal, air yang diminum juga akan lansung turun ke tubuh bagian bawah sehingga tidak tertampung di dalam lambung, yang nantinya akan dipompa jantung ke seluruh organ tubuh.

Historiografi Hadis dalam Aliran Islam: Mengulas Sejarah Penulisan dan Penghimpunan Hadis Sunni Syiah
Authors: Batu Anugrah Eran
Published: July 2024

Kajian seputar penulisan sejarah hadis tidak lagi berfokus pada masing-masing aliran, namun mulai menyorot historiografi hadis antara Sunni dan Syiah. Studi ini bertujuan untuk memaparkan historiografi hadis dalam aliran dengan mengulas penulisan dan penghimpunan hadis Sunni dan Syiah. Terdapat dua pertanyaan yang diajukan yaitu: pertama, bagaimana sejarah kemunculan Sunni dan Syiah? Kedua, bagaimana sejarah kompilasi, kodifikasi serta perangkat metodeologi hadis di kalangan Sunni dan Syiah? Adapun metode dalam penelitian ini yaitu metode kualitatif dengan jenis studi literatur dengan konsep historiografi sebagai pendekatan penelitian. Penelitian ini menyimpulkan bahwa kelompok Sunni umumnya meyakini bahwa Hadis belum ditulis secara resmi selama abad pertama Hijriah, karena pada awalnya hadis dilarang untuk ditulis dan sahabat memiliki hafalan yang kuat, meskipun dikemudian hari pendapat ini dipertanyakan oleh sarjana kontemporer. Selama periode Atba' al-Tabi'in, hadis dikompilasi dan dikodifikasi secara sistematis menurut bab atau subjek tertentu, menghasilkan kitab-kitab hadis utama Sunni seperti Kutub al-Sittah. Setelah periode tersebut, berbagai kitab hadis dengan berbagai metode dan materi mulai disusun. Di sisi lain, Syiah percaya bahwa kompilasi dan kodifikasi hadis dimulai sejak masa Nabi, melalui beberapa fase seperti periode awal sejarah Syiah, Ushul Arba’miah, dan kodifikasi yang menghasilkan Kutub al-Arba’ah serta periode penyempurnaan. Kajian sejarah hadis pada Sunni dan Syiah menampakkan langkah-langkah metodologis seperti pengumpulan, penyusunan, dan kritik hadis. Metode pengumpulan hadis menjadi sumber penting bagi penulisan sejarah Islam, terutama dalam bentuk al-Sirah dan al-Maghazi, sedangkan metode kritik hadis membantu menyaring informasi sejarah yang valid dan mendukung perkembangan historiografi hadis di kalangan Sunni dan Syiah.

This study aims to examine the effect of good corporate governance on firm value. In addition, this study also examines the role of environmental costs in moderating the effect of good corporate governance on firm value. This research was conducted on go public companies included in the LQ45 index list from 2018 to 2022, with purposive sampling. The data was analyzed using panel data with the weighted least square method. Measurement of good corporate governance uses a score based on the corporate governance perception index, while firm value is measured by the Tobins'Q ratio. Meanwhile, the moderating variable of environmental costs is measured based on Corporate Social Responsibility costs. The results showed that good corporate governance negatively affects firm value. This study did not succeed in proving the moderation of environmental costs on the relationship between good corporate governance and firm value. This research is expected to be the basis for investors in making investment decisions through information about the effect of environmental costs on the relationship between good corporate governance and firm value.

Podocnemis unifilis is an important source of protein for indigenous communities in the Brazilian Amazon. However, contaminants associated to the mining activities can be affecting this species and, in turn, its consumers. The objective of this study was to evaluate the risk of Hg contamination that the Kayapó indigenous people are exposed to through the consumption of P. unifilis in a region affected by mining in the Baú river basin, municipality of Altamira-PA, Brazilian Amazon. Muscle (edible) samples of the collected specimens were digested in a solution of concentrated nitric acid with hydrogen peroxide using a microwave digestion system. Inductively coupled plasma emission spectrometry with hydrogen generation was used to quantify HgT. The health risk assessment was performed according to the methodology proposed by the U.S. Environmental Protection Agency. The muscle of P. unifilis presented an average concentration of 0.022 (µg/g wet weight) HgT, a value within the allowed level for the dietary pattern. The risk assessment for human health shows that the consumption of P. unifilis presents low risks of intoxication by Hg for the indigenous people. The results show a reduced risk of exposure to Hg due to the consumption of P. unifilis by indigenous people. However, if mining activity continues to spread across the region, since Hg biomagnifies in the trophic chain and can represent a serious risk for human health and biota.

HIV infection is a nowadays pathology that affect persons from all of the world. Pathogenesis of the HIV-infection and cancer is a great problem, with a complexity directions in research. More important in HIV infection to patients, is also to take into consideration others things, such as prevention, diagnosis, monitoring, treatment, including control measures. This previously mentioned, should be supported by statistical studies that report on restricted or extended geographical areas, to the level of social class and age. In our written text we try to describe from our opinion, strategies in HIV, infection, status knowing as a social and as a healthcare problem.
Euclidean Relativity Solves the Hubble Constant Tension
Authors: Niemz Markolf H.
Published: July 2024

Einstein’s special relativity (SR) and general relativity (GR) describe nature in “subjective concepts” (concepts of an observer), such as relative spacetime, wave, particle, and force. Despite the Lorentz covariance of SR and the general covariance of GR, an observer’s perspective is always egocentric. Coordinate-free formulations of SR/GR or multiple egocentric perspectives do not provide a “holistic view of nature” (comprehensive view of nature from all possible perspectives at the same instant in time) because there is no absolute time in SR/GR. Here I show: Euclidean relativity (ER) describes nature in “objective concepts” (concepts that are immanent in all objects). “Pure distance” replaces spatial and temporal distance. “Pure energy” replaces wave and particle. Each object’s proper space d1, d2, d3 and its proper time τ span an absolute 4D Euclidean spacetime (ES), where d1, d2, d3 and d4 = cτ are pure distances. All energy moves through ES at the speed of light c. An object’s proper time flows in the direction of its 4D motion. Thus, there is a relative 4D vector “flow of proper time”. The invariant parameter is absolute, cosmic time t. An observer’s reality is created by projecting ES orthogonally to his proper space and to his proper time. ER neither competes with nor replaces SR/GR. ER complements SR/GR by adding a holistic view. ER describes the “master reality” ES, whereas SR/GR describe an observer’s reality. The holistic view solves 15 fundamental mysteries geometrically, in particular in cosmology and quantum mechanics. Examples are time’s arrow, the horizon problem, the Hubble constant tension, dark energy, entanglement, and the baryon asymmetry.
Alena Tensor and Its Possible Applications in Unification Theories
Authors: Ogonowski Piotr , Skindzier Piotr
Published: July 2024

Alena Tensor is a recently discovered class of energy-momentum tensors that provides mathematical framework in which, as demonstrated in previous publications, the description of a physical system in curved spacetime and its description in flat spacetime with fields are equivalent. The description of a system with an electromagnetic field based on the Alena Tensor can be used to reconcile physical descriptions. In curvilinear description, EFE were obtained with Cosmological Constant related to the invariant of the electromagnetic field tensor, which can be interpreted as negative pressure of vacuum, filled with electromagnetic field. In classical description for flat spacetime, three densities of four-forces were obtained: electromagnetic, gravity, and the force responsible for the Abraham-Lorentz effect (radiation reaction force). There was obtained Lagrangian density and generalized canonical four-momentum, containing electromagnetic four-potential and a term responsible for other two forces. In the quantum picture, QED Lagrangian density simplification was obtained, and the Dirac, Schrödinger and Klein-Gordon equations may be considered as approximations of the obtained quantum solution. The distribution of charged matter was expressed as polarization-magnetization stress-energy tensor, what may explain why gravity is invisible in QED. The description used also leads to conclusion, that charged particles cannot remain at complete rest and that they should have spin. Obtained connection of Einstein tensor with gravity and radiation reaction force, after transition to curvilinear description, excludes black hole singularities. Farther use of Alena Tensor in unification applications was also discussed.
How Long Can the Spiral Arms of Disc Galaxies Be Optically Observed?
Authors: Pan Hongjun
Published: July 2024

With the galaxy J101652.52 as a model galaxy, this paper studied on the temporal duration of optically observed spiral patterns in disc galaxies is based on the finite reservoir of hydrogen available without replenishment following the initial formation of these well-isolated galaxies. The galaxy J101652.52 exhibits a grand design spiral pattern of two wide open spiral arms with perfect central symmetry, has only rear side trail effect, which clearly indicates that there is no corotation circle, therefore, the Density wave theory proposed for the spiral arm formation may not be applicable in this galaxy. The results reveal a gradual decline in observable spiral arms regardless of any spiral arm formation mechanism. This reduction occurs after half-loop rotation (as defined in the paper) as hydrogen reserves deplete, hindering new star formation. Ultimately, spiral patterns may possibly become optically invisible at normal conditions after a full-loop rotation (as defined in the paper) with hydrogen depletion, even if the formation mechanism remains active. The spiral galaxies with spiral arms decoupled from galactic bars or having soft spiral structures shall have similar results as long as that the spiral pattern rotation speed is significant different from the galactic matter rotation speed. Most of observed spiral galaxies have soft spiral structures, their spiral patterns dynamically change constantly. The results of this study support the idea of short-lived spiral patterns compared to the lifespan of the spiral galaxies. The spiral arm formation may occur once like the onetime firework show in a galaxy’s life based on the limited availability of hydrogens. A concise, universally applicable mechanism for spiral arm formation across various galaxies should exist which provides a single mathematical formula to describe the broad range of morphologies of the spiral arms with few adjustable parameters. Some exceptions may be explained within this framework. Furthermore, the observed data on spiral pattern and galactic bar rotation speeds in the Milky Way require rigorous verification, particularly concerning the winding problem.

Internships can foster educational alliances between industry (business environment) and academic institutions, which can facilitate both flexibility and accelerated innovation. The purpose of this research is to search for the factors that determine HRD through the implementation of the Internship program among the students of Democritus University of Thrace and reveal the correlation between the factors. Also, this paper investigated the impact of the COVID-19 Eras on Human Resource Development (HRD) Factors and finally, investigated the correlation between the two variables "Recruitment in the specialization" and "Covid Eras". The sample of the research consisted of 1398 students of DUTh who implemented Internships during the academic years 2015-2016 to 2021-2022. A questionnaire with 60 variables was created for data collection. A random sampling method was applied to collect the sample. From the results of the survey, ten factors were extracted for human resource training that explained 75.512% of the total variance and for each one, Cronbach's Alpha reliability was tested, which was high. In detail, the factors revealed were Learning Outcomes, Efficacy, Emotional Commitment, Satisfaction, Participation, Empowerment, Role Ambiguity, Role Conflict, Supervisor and Collaboration. From the results of the study, it was evident that HR development - training is a multi-dimensional concept and is a necessary condition for the competitiveness of the firms. Training can help to improve the flexibility of the firm, but also to motivate the staff by implementing multidisciplinary training programs. In general, internship programs are valuable ways for students to acquire broad competences, where the practical knowledge gained supports and complements the theoretical studies acquired in educational institutions.
