-Objetivos: Determinar el puntaje en las dimensiones del Síndrome de Burnout (SB), según el año de estudio entre los estudiantes de medicina de ocho países de América Latina.
-Métodos: Estudio analítico transversal, realizado en 2649 estudiantes de medicina de nueve universidades en ocho países de América Latina, durante el 2016-2017. Para el presente estudio, se aplicó la prueba Maslach Burnout Inventory-Student Survey (MBI-SS), con el que se obtuvieron las tres dimensiones: agotamiento, autoeficacia y cinismo, que se cruzaron en el programa Stata 11,1 según el año de estudio y se ajustó con los Modelos Lineales Generalizados (GLM, por sus siglas en inglés), por el sexo, la edad, el tipo de universidad y la sede de encuestado.
-Resultados: En el análisis multivariado se encontró que, conforme se incrementaba el año de estudio aumentó el puntaje en el agotamiento (tercer año: +2,6 puntos, valor p<0,001; cuarto año: +1,8 puntos, valor p=0,028 y quinto año: +3 puntos, valor p=0,007). Los puntajes en la autoeficacia y el cinismo, no tuvieron variaciones estadísticamente significativas, según el año de estudio. Además, las mujeres tuvieron un mayor puntaje en agotamiento (+0,7 puntos, valor p=0,006) y menor en cinismo (-0,5, valor p<0,001).
-Conclusiones: El puntaje en el agotamiento aumenta según incrementa el año académico, pero los otros componentes no mostraron un cambio significativo, obteniendo las mujeres mayor puntaje en agotamiento, aunque menor en cinismo. Las instituciones educativas deben generar programas de detección de estos estudiantes, brindándoles estrategias de apoyo académico.

Authors: Cárdenas Juan Francisco , Sotomayor Ana Cristina 
Published: August 2021

Introducción: Tumores primarios más comunes, aunque la mayoría son benignos, su ubicación en el sistema nervioso central puede causar una grave morbimortalidad. Este tipo de neoplasia tiene una incidencia de 7.7 por 100000 habitantes con una incidencia variable entre cada región siendo de un 3.8% en fosa media, 10% de fosa posterior y un 36% de todos los tumores intracraneanos. Dependerán de varios factores de riesgo asociados a su desarrollo desde causas genéticas a ambientales.
A pesar de la naturaleza histológica benigna de estos tumores, los pacientes sufren síntomas neurológicos y requieren tratamiento. La cirugía sigue siendo el tratamiento primario; la radiación se puede usar como tratamiento primario o, comúnmente, para lesiones recurrentes o inaccesibles.
Materiales y Métodos: Se realizó una revisión bibliográfica en base de datos de PubMed, ClinicalKey, Google Scholar, Medline, UpToDate y Science Direct además uso de casos clínicos, repositorios y previas revisiones para la realización de este trabajo. La búsqueda se restringió a los años 2017 al 2019
Resultado: Este tipo de neoplasias causan síntomas por efecto de masa y su mayoría en fosa media la afectación es de tipo visual y auditiva y fosa posterior existen síntomas vestibulares. Con resolución quirúrgica principalmente.
Conclusiones: El diagnostico debe ser clínico, el cual a pesar de tener ciertos rasgos parecidos difiere en varios casos por las estructuras adyacentes involucradas por lo que se puede complementar con estudio imagen. La elección del tratamiento deberá ser individualizado

Quasi-1500-Year-Cycle Signal in Length-of-Day Change
Authors: MA Lihua 
Published: August 2021

Abstract
Length-of-day (LOD) change, i.e., variations in Earth’s rotation rate, includes the long-term slowdown trend, as well as periodic and irregular fluctuations. The current continuous sequence of the LOD change covers a time span of <400 years. Using astronomical records in ancient historical documents, combined with a modern astronomical ephemeris, it is possible to obtain ancient LOD change. Some scholars have given a discontinuous LOD data series for the past 4000 years. In this paper, the author uses the Lomb–Scargle periodogram to study the LOD series and finds a significant quasi-1500-year-cycle signal. Furthermore, with weighted wavelet Z-transform, time-varying characteristics of the cycle in the LOD change are obtained.

Authors: Paniagua-Molina Javier , Solórzano-Thompson Johanna , González-Blanco Carlos , Barboza-Navarro David 
Published: August 2021

Abstract
As the number of homes located in condominiums increases, investigations should be promoted to determine the implied price of additional amenities over the total price of the property. This study evaluated the impact of multi-attribute and construction variables on the value of condominiums in Costa Rica, using a hedonic pricing model of the amenities that influence the total price. Information from condominiums located in all provinces of the country was used to determine the importance of the variables studied. Through multiple regression analysis, it was determined that nine amenities explain the behavior of the total price. This study shows that the project’s internal and external variables have a significant effect on sales prices and consumers’ purchasing decisions. The most significant variables were income, construction area, access to a pool and gym, and the type of condominium.

Authors: Anih Paul C. , Usenemana Sunday 
Published: August 2021

Abstract
Variance in the cost method of valuation as caused by certain variables is objectionable in the profession of estate surveying and valuation at both local and international best practices. The study aimed at determining the variables for the variance in the application of the cost method of valuation for estate surveying and valuation practice in Uyo. The sample of the population used for the research comprised 110 estate surveyors in Uyo. The survey method was used for the research. The sampling technique was purposive sampling. The data were analyzed using standard deviation and analysis of variance (ANOVA). The findings showed that depreciation rates of σ2 =113.974 and σ = 10.676 were over 60% of the total variance of values among estate surveyors and valuers. The construction rates and errors in manual measurements and computation of areas, volumes and dimensions showed σ2 = 6.004 and σ = 2.4503, which accounted for 15% of total variance. The study recommends the use of a regional-based scientific approach to measure depreciation for consistency and high precision. Automated techniques, such as GPS, AutoCAD, Google Earth pro, are recommended to minimize variance in measurements.

Published: August 2021

Abstract
This paper assesses the impact of outbreaks from the perspective of volatility of Malaysian Listed Property Companies in mixed-asset portfolios, concentrating on periods of time between outbreaks. The real issue of this study is the health crisis that has troubled institutional investors, as it has already significantly impacted the returns on investments. Investors need to be better informed on the impact of health outbreaks on investments in order to minimize their impact. To assess the impact of the outbreaks, the GARCH method has been employed to examine the dynamic volatility of listed property companies in mixed-asset portfolios. The volatility level will give investors better information from point of view of the dynamics of volatility of the Malaysian listed property companies’ performance within mixed-asset portfolios. The findings show that listed property companies demonstrate high volatility compared to other mixed-asset portfolios during the periods of outbreaks. This indicates Malaysian listed property companies were the most volatile investment in mixed-asset portfolios. This empirical study will contribute significantly to institutional investors, especially in terms of the investment decision-making process during outbreaks.
Malignant granular cell tumor of the arm – case report
Authors: Mehedinţu Mihai , Danciu Răzvan , Toma Anca I. , Ştefan Corina , Jecan Cristian R. 
Published: August 2021

Abstract
Granular cell tumor (GCT) is a rare form of soft tissue cancer that is usually benign. Its malignant evolution is encountered in less than 2% of cases, having a more rapid and unfavorable evolution. Clinical presentation betraying malignant features could be increased tumor size, rapid growth, deep localization, and female gender.
This paper presents the case of a 52-year-old patient with a hard, rapidly evolving tumor in the left arm. The diagnosis of granular cell tumor was made based on histopathological examination using the Fanburg and Smith criteria to differentiate the formation as malignant, but with certainty this was subsequently confirmed by the existence of a metastasis. Surgical excision was performed and the evolution was favorable.
Evolution and treatment differ depending on the benign or malignant form, but surgical treatment with wide local excision is recommended. This may be followed by chemotherapy or radiotherapy, and follow-up of patients for the rest of their lives is mandatory.
Posterior interosseous nerve entrapment by intramuscular lipoma arising from the supinator muscle - a case report
Authors: Refai Omar , Elsherif Mohamed Eslam , Khalifa Ahmed A. 
Published: August 2021

Abstract
Background: Lipomas are benign, slow-growing tumors frequently subcutaneous and asymptomatic, intramuscular lipoma constituting a rare subtype. However, a lipoma occurring nearby the proximal radius may cause posterior interosseous nerve (PIN) entrapment.
Case presentation: We described an uncommon case of a 45-year-old-man with a history of progressive, painless proximal right (dominant) forearm swelling for 4 months associated with PIN entrapment syndrome, presenting as fingers extension weakness. Intramuscular lipoma was observed in the supinator muscle in the magnetic resonance imaging (MRI). Lipoma surgical excision and release of the PIN through proximal forearm direct anterior approach was performed.
Results: The histopathological examination confirmed the diagnosis of benign intramuscular lipoma. The follow-up of the patient showed full recovery within three months postoperatively.
Discussion: Intramuscular lipoma is rare; however, it could originate from supinator muscle in the forearm, presenting with vague pain and could lead to compression of nearby neurovascular structures such as the PIN. Clinical evaluation and imaging studies, especially MRI, are crucial for diagnosis. If neural compression is evident, surgical resection is mandatory.
Conclusion: Intramuscular lipoma entrapping PIN is rare and requires early clinical diagnosis confirmed by imaging and neurophysiological studies, surgical excision being the method of choice for optimum functional outcomes.
Current review of surgical management options for total knee arthroplasty in the rheumatoid knee
Authors: Iordache Sergiu Andrei , Şerban Bogdan , Popa Mihnea Ioan Gabriel , Cursaru Adrian 
Published: August 2021

Abstract
Rheumatoid arthritis (RA) represents a condition that can erode cartilage and damage joints, leading to inflammation and loss of movement, characterized by inflammatory synovitis. While the widespread use of potent disease-modifying medications has increased opportunities for RA patients, orthopedic surgery and complete joint arthroplasty remain an important option in end-stage joint treatment. The knee is one of the most frequently affected joints in chronic rheumatoid arthritis patients. The severity of RA ranges from a moderate illness to a serious, rapidly progressing, destructive version, gradually leading to incessant pain and joint deformity. Despite recent advances in biological agents and therapeutic modalities in the field of rheumatology, certain patients with RA, who ultimately undergo joint surgery, tend to experience progressive joint damage. Though, TKA can be performed in these patients, increased complications and poorer outcomes may result after total knee arthroplasty, because of the particularities given by RA. They are associated with extended operating time, specifically resulting in increased infection, blood loss and deep vein thrombosis. However, because RA patients present additional risk factors for complications, certain critical preoperative examination and surgical aspects need to be considered in order to maximize TKA outcomes in this subgroup of patients.

Published: August 2021

Abstract
Although the introduction of specific guidelines regarding the acute management of trauma patients have resolved many inconsistencies in the acute treatment pathways, grey areas are still preventing consensus and unitary standards of care. The treatment of splenic injuries has seen a notable shift from splenectomy only in the early 20th century to mainly non-operative contemporary approaches. However, there is no current agreement on the optimum timing of switching from conservative to operative decisions, raising the legitimate question of whether some patients are put at risk by waiting too much or other patients are deprived of a necessary organ by not waiting enough.
This paper focuses on the non-operative paradigms of blunt splenic injuries and their immediate and long-term clinical implications presented as a short narrative review. It presents the historical perspective on the treatment of splenic injuries, the role of surgery and selective angioembolisation and their repercussions on the immunological functions of the spleen.

Authors: Patrus Ângela , Moreira Mariana Luiza , Bacha Fernanda Vaz de Melo , Porto Anna Clara Colen , Vianna Gláucia dos Santos 
Published: August 2021

Objetivo: Analisar a prevalência geral e de acordo com as variáveis “sexo” e “faixa etária” das dermatoses de um serviço no ano 2019 e descrever o perfil epidemiológico dos pacientes. Métodos: Trata-se de estudo transversal, que analisou prontuários de 717 pacientes atendidos no serviço de dermatologia de um ambulatório universitário de uma capital brasileira no ano de 2019. Analisou-se o perfil epidemiológico dos pacientes, considerando as variáveis: sexo, idade, profissão e naturalidade. Avaliou-se a prevalência dos diagnósticos de forma global e de acordo com faixas etárias e sexo. O estudo foi aprovado pelo Comitê de Ética e Pesquisa. Resultados: As variáveis mais prevalentes foram: sexo feminino, 20 a 59 anos, naturalidade no estado de Minas Gerais e profissões aposentado, do lar e estudante. O grupo de diagnósticos mais prevalente foi discromias, seguido por tumores epiteliais benignos, micoses superficiais, erupções eczematosas e foliculoses. Conclusão: O perfil epidemiológico encontrado, incluindo sexo, faixa-etária, profissão e naturalidade, foi condizente com literatura. Ainda, a prevalência dos principais diagnósticos diferiu conforme a variável epidemiológica dos pacientes. Este resultado condiz, de forma não ordinal, com as principais hipóteses dos demais estudos. Entretanto, a falta de trabalhos com avaliações epidemiológicas semelhantes limita a análise comparativa adequada.

Authors: Kurup Amritha Sabitha , Parambath Fairoz Cheriyalingal , Khader Anza , Raji Thazhathekandy , Jose Beena Philomina 
Published: August 2021

Objectives:
The objectives of the study were to determine the in vitro susceptibility of dermatophyte species, isolated from the clinically diagnosed lesions of cutaneous dermatophytosis to fluconazole, and terbinafine.

Materials and Methods:
The skin scrapings from clinically diagnosed lesions of cutaneous dermatophytoses were cultured in Sabouraud dextrose agar to identify the causative dermatophyte. Antifungal susceptibility testing was performed using microbroth dilution assay.

Results:
During the study period, 94 specimens from clinically diagnosed lesions of cutaneous dermatophytoses were received for fungal culture. Dermatophytes were identified as the causative agent in 44 specimens (Trichophyton rubrum was identified in 18/44 (40.9%), Trichophyton mentagrophytes in 17/44 (38.6%), Trichophyton interdigitale in 5/44 (11.4%), and Nannizia gypsea in 4/44 (9.1%) isolates). Minimum inhibitory concentration (MIC) of fluconazole was ≥64 µg/ml in 22.7% (10/44) and MIC of terbinafine was ≥0.5 µg/ml in 36.4% (16/44) of specimens. When compared to fluconazole, terbinafine showed a lower MIC 50 of 0.0019 µg/ml for Nannizia gypsea.

Limitations:
Small sample size and lack of clinical correlation were the major limitations of the study. Antifungal susceptibility testing limited to fluconazole and terbinafine was another limitation of the study.

Conclusion:
Trichophyton rubrum was the most common isolate identified in culture of scrapings from clinically diagnosed lesions of cutaneous dermatophytosis. A rising trend in MIC values of isolates to terbinafine and fluconazole was observed.

Authors: Saruta Wakiko , Takahashi Toshiyuki , Kumabe Toshihiro , Minami Manabu , Kanematsu Ryo , Ohtaki Hiroya Shimauchi , Otsuka Ryotaro , Hanakita Junya 
Published: August 2021

Background:
There have been many reports on the clinical, radiographic, and surgical management of thoracolumbar burst fractures attributed to high-energy trauma. Interestingly, few reports have described how to extract bone fragments associated with these injuries protruding into the spinal canal contributing to significant neurological deficits.

Methods:
An 18-year-old male presented with a severe L3-level paraparesis (i.e., loss of motor/sensory function below L3 lower extremity hyporeflexia, and sphincter dysfunction: American Spinal Injury Association [ASIA] Impairment Scale B) following a high-speed crash. The computed tomography and magnetic resonance studies revealed a L3 burst fracture with bone fragments protruding into the spinal canal causing marked cauda equina compression. Following a L3-L4 laminectomy, and opening of the dorsal dura, the bone fragments were ventrally impacted into the fractured L3 vertebral body a pedicle/screw L1-L5 fusion was then completed.

Results:
One month later, the patient recovered to an ASIA Scale of C, (i.e., residual proximal 3/5 and distal 2/5 motor deficits, with partial sensory sparing).

Conclusion:
Transdural ventral impaction of protruded bone fragments attributed to high speed lumbar burst fractures contributing to significant cauda equina compression can be safely/effectively accomplished.

Published: August 2021

Purpose: İzmir is the province of Turkey with the highest lung cancer incidences for males, therefore a comparative study was performed in particular districts of İzmir in 2013. In the study, it was aimed to assess the association between lung cancer risk and indoor radon.
Methods: Patients diagnosed with lung cancer between 2010 and 2011 were selected from the database of the Izmir Cancer Registry (ICR). Measurements of indoor radon concentrations were performed in a total of 117 locations using the SSNTD (Solid State Nuclear Track Detectors) method with LR-115 detectors. Indoor radon concentration measured in homes of patients with lung cancer and cancer free group were compared statistically.
Results: The indoor Radon (222Rn) activity concentration detected ranged from 165 to 487 Bq/m3, for the lung cancer group, from 28 to 367 Bq/m3 for the cancer free group, with geometric means of 269 Bq/m3 and 123 Bq/m3, respectively.
Conclusion: According to the logistic regression model, as radon concentration and package/year increased, the rate of cancer increased multiple folds. These results suggest that indoor radon levels may contribute to higher rates of lung cancer for İzmir compared to the rest of the country, and indoor radon levels may be a contributory factor in this phenomenon.

Published: August 2021

Purpose: The aim of the study was to observe the relationship between age, body mass index (BMI), physical activity, and kyphosis angle parameters with respiratory function capacity in community-dwelling older adults and to determine the main predictor.
Methods: A prospective cross-sectional study was carried out with 70 older adults. Physical activity level was questioned with the Physical Activity Scale for Elderly (PASE). Thoracic kyphosis degrees were measured with a digital inclinometer. Pulmonary Function Test (PFT) was used to measure pulmonary function capacity. The correlation between age, BMI, PASE, thoracic kyphosis angle with parameters of PFT measurement was analyzed. In addition, a linear multivariate regression model was built to determine the main predictor.
Results: The mean age of the participants was 69.88±4.52 years. There was a low degree but a statistically significant positive correlation between BMI and FEV1 (r=0.258,p
