Alunos canhotos de odontologia da cidade de Uberlândia: perfil, ergonomia e dores osteomusculares / Left-handed dentistry students in the city of Uberlândia: profile, ergonomics and muscular pain

Os dentistas são um grupo de alto risco para o desenvolvimento de doenças de desordens musculoesqueléticas e tendo em vista que o sistema de produção industrial desenvolve produtos que atendem a maioria da população destra, os estudantes canhotos precisam se adequar a uma formação acadêmica, usando instrumentais, cadeiras odontológicas eoutros objetos projetados para destros. O presente trabalho teve como objetivo a coletade informações sobre os canhotos nos cursos de Odontologia da cidade de Uberlândia ­Minas Gerais. Foram incluídos todos os alunos canhotos matriculados no ano de 2022 e que estavam cursando ou já cursaram disciplinas com atividades laboratoriais ou clínicas. Questionários foram aplicados para identificação do perfil, das dificuldades, da ergonomia e das dores osteomusculares dos alunos canhotos em suas atividades. Os dados foram em seguida tabulados e passaram por análise estatística. Da quantidade total de alunos das três instituições (n=1.578), foram entrevistados 45 (2,8%) alunos canhotos, sendo a maioria feminina (80%), na qual identificou-se um posicionamento inadequado do operador canhoto quando comparado ao preconizado pela ISO-FDI, além da limitação de movimento na presença de auxiliar (82,2%). Os locais com maior frequência de dor/desconforto foram: pescoço (79%), costas superior esquerda (63%) e inferior esquerda (61%) e punhos/ mãos esquerda (56%). A intensidade da dor variou entre alguma, moderada e bastante. O impedimento de realizar atividades diárias foi relatado por 17% dos alunos (n=7) e destes somente 1 buscou atendimento médico. Não houve diferença estatística na comparação entre instituição pública e privada. Diante dos resultados, concluiu-se que os canhotos representam minoria dos alunos de Odontologia e apresentam várias regiões de dor/ desconforto devido às adaptações e posturas erradas durante os atendimentos. Apesar de grande parte apresentar dor, poucos tiveram impedimento de atividades rotineiras ou procuraram ajuda médica(AU)

Dentists are a high risk group for the development of musculoskeletal disorders and considering that the industrial production system develops products that serve the majority of the right-handed population, lefthanded students need to adapt to an academic training, using instruments, dental chairs and other objects designed for right-handers. This study aimed to collect information about left-handers in Dentistry courses in the city of Uberlândia - Minas Gerais. All left- handed students enrolled in the year 2022 and who were taking or had taken courses with laboratory or clinical activities were included. Questionnaires were applied to identify the profile, difficulties, ergonomics and musculoskeletal pain of left-handed students in their activities. The data were tabulated and then undergo statistical analysis. Of the total number of students from the three institutions (n=1,578), 45 (2.8%) left-handed students were interviewed, the majority being female (80%), in which an inadequate positioning of the left-handed operator was identified when compared to the recommended one by ISO-FDI, in addition to limitation of movement in the presence of an assistant (82.2%). The places with the highest frequency of pain/discomfort were: neck (79%), upper left back (63%) and lower left back (61%) and left wrists/hands (56%). The intensity of pain varied between some, moderate and a lot. The impediment to carrying out daily activities was reported by 17% of the students (n=7) and of these, only 1 sought medical attention. There was no statistical difference when comparing public and private institutions. In view of the results, it was concluded that left-handers represent a minority of dentistry students and have several regions of pain/discomfort due to adaptations and wrong postures during consultations. Although most of them had pain, few were prevented from performing routine activities or sought medical help(AU)

Progression of valve heart disease in a cohort of patients undergoing renal replacement therapy / Progressão da doença cardíaca valvar em coorte de doentes em terapia renal substitutiva

Abstract Introduction: Cardiovascular disease is an important cause of death among patients with chronic kidney disease (CKD). Valve calcification is a predictor of cardiovascular mortality and coronary artery disease. Objective: To assess heart valve disease frequency, associated factors, and progression in CKD patients. Methods: We conducted a retrospective study on 291 CKD patients at Hospital das Clínicas de Pernambuco. Inclusion criteria were age ≥ 18 with CKD and valve disease, while those on conservative management or with missing data were excluded. Clinical and laboratory variables were compared, and patients were categorized by dialysis duration (<5 years; 5-10 years; >10 years). Statistical tests, including chi-square, Fisher's exact, ANOVA, and Kruskal-Wallis, were employed as needed. Simple and multivariate binary regression models were used to analyze valve disease associations with dialysis duration. Significance was defined as p < 0.05. Results: Mitral valve disease was present in 82.5% (240) of patients, followed by aortic valve disease (65.6%; 86). Over time, 106 (36.4%) patients developed valve disease. No significant association was found between aortic, pulmonary, mitral, or tricuspid valve disease and dialysis duration. Secondary hyperparathyroidism was the sole statistically significant factor for mitral valve disease in the regression model (OR 2.59 [95% CI: 1.09-6.18]; p = 0.031). Conclusion: CKD patients on renal replacement therapy exhibit a high frequency of valve disease, particularly mitral and aortic valve disease. However, no link was established between dialysis duration and valve disease occurrence or progression.

Resumo Introdução: Doenças cardiovasculares são uma causa significativa de morte em pacientes com Doença Renal Crônica (DRC). A calcificação valvar é preditor de mortalidade cardiovascular e doença arterial coronariana. Objetivo: Avaliar a frequência, fatores associados e progressão de valvopatias em pacientes com DRC. Métodos: Coorte retrospectiva com 291 pacientes ambulatoriais no Hospital das Clínicas de Pernambuco. Inclusão: ≥18 anos com DRC e valvopatia; exclusão: tratamento conservador ou dados incompletos. Variáveis clínicas e laboratoriais foram comparadas e categorizadas por tempo de terapia dialítica (TTD): <5 anos, 5-10 anos, >10 anos. Foram aplicados os testes Qui-quadrado, exato de Fisher, ANOVA, Kruskal-Wallis. Associação entre valvopatia e TTD foi avaliada por regressão binária. Significância foi definida como p < 0,05. Resultados: A valvopatia mitral foi encontrada em 82,5% (240) dos casos, seguida da aórtica (65,6%; 86). Houve progressão da doença valvar em 106 (36,4%) pacientes. Não houve associação entre valvopatias aórtica, pulmonar, mitral ou tricúspide e TTD. Hiperparatireoidismo secundário foi a única variável explicativa significativa na regressão para valvopatia mitral (OR 2,59 [IC95%: 1,09-6,18]; p = 0,031). Conclusão: Encontramos alta frequência de valvopatias, especialmente mitral e aórtica, aem pacientes com DRC. Não houve associação entre TTD e valvopatia.

Vocal Load of University Professors: Preliminary Results

Purpose: To describe the acoustic characteristics of a classroom, voice quality, fatigue, and vocal load of university professors. Methods: Exploratory, observational, longitudinal, and descriptive study with a single group of participants, including vocal monitoring data over two weeks. Acoustic characterization of the classroom, perceptual-auditory evaluation, and acoustic analysis of voice samples were conducted before and after classes. Vocal dosimetry was performed during classes, and the Vocal Fatigue Index (VFI) was assessed at the beginning of each week. Descriptive analysis of the findings was conducted, and randomization test was performed to verify the internal reliability of the judge. Results: All participants reported speaking loudly in the classroom, with the majority reporting vocal changes in the past six months, and only one participant reported a current vocal change. The classroom had acoustical measures and estimations that deviated from established standards. The professors used high vocal intensities during classes. After the classes, an increase in the absolute values of the aggregated data for CAPE-V, jitter, and fundamental frequency was found, varying within the range of normality. Furthermore, there was an observed increase in both post-lesson intensity and VFI when comparing the two-week period. Conclusions: Vocal intensities and VFI were possibly impacted by the acoustics of the classroom. The increase in average VFI between the weeks may be attributed to a cumulative fatigue sensation. Further research with a larger number of participants and in acoustically conditioned classrooms is suggested in order to evaluate collective intervention proposals aimed at reducing the vocal load on teachers.

Objetivo: Describir las características acústicas, calidad vocal, fatiga y carga vocal de profesores universitarios. Métodos: Estudio exploratorio, observacional, longitudinal, descriptivo con un solo grupo de participantes y datos de monitoreo vocal durante dos semanas. Se realizó caracterización acústica de la sala, evaluación auditiva-perceptiva y acústica de muestras de voz antes y después de las clases. Se realizó dosimetría vocal durante las clases y se verificó el Índice de Fatiga Vocal (IFV) en dos semanas. Se realizó un análisis descriptivo de los hallazgos y una prueba de aleatorización para verificar la confiabilidad interna del juez. Resultados: Todos los participantes informaron hablar en voz alta en clase, la mayoría informó cambios vocales en los últimos seis meses y solo uno informó cambios vocales actuales. La sala presentó mediciones y estimaciones acústicas fuera de las normas establecidas. Los profesores utilizaron intensidades vocales altas durante las clases. Hubo un aumento en los valores absolutos de los datos agrupados para CAPE-V, jitter y frecuencia fundamental, variando dentro de los límites normales, después de las clases. La intensidad después de las clases y el IFV, en la comparación entre las dos semanas, mostraron un aumento. Conclusiones: La dosis vocal y el IFV posiblemente se vieron afectados por la acústica del aula. El aumento del IFV medio entre semanas pudo deberse a la sensación de cansancio acumulada. Se sugieren nuevas investigaciones con un mayor número de participantes y que se realicen en la sala acondicionada acústicamente para evaluar propuestas de intervención colectiva, con el objetivo de reducir la carga vocal de los docentes.

Tratamento reabilitador com prótese obturadora em paciente acometido por maxilectomia parcial: relato de caso / Rehabilitative treatment with obturator prosthesis in a patient suffering from partial maxillectomy: case report

Introdução: O tratamento de tumores malignos ou benignos, podem resultar em procedimentos cirúrgicos, como a maxilectomia parcial ou total, gerando comunicação bucosinusal nos pacientes. Uma forma de resolver estas alterações maxilofaciais é através do tratamento reabilitador com próteses obturadoras a fim de restabelecer a função mastigatória, estética, fonética e psicológica. Objetivo: o objetivo deste trabalho foi relatar o caso clínico de um paciente oncológico que foi reabilitado com prótese obturadora devido à maxilectomia por neoplasia maligna de seio maxilar. Relato de caso: Paciente de 62 anos, sexo masculino, procurou atendimento odontológico no Centro de Oncologia Bucal da Universidade Estadual Paulista "Júlio de Mesquita Filho" (UNESP) de Araçatuba ­ SP após a realização de uma maxilectomia parcial com comunicação bucosinusal e foi encaminhado para o Curso de Especialização em Prótese Dentária da Faculdade de Odontologia ­ Unesp/Araçatuba-SP para a reabilitação. Foi proposto, primeiramente a realização da prótese obturadora para fechar a comunicação bucosinusal e uma prótese total inferior para o arco antagonista e, posteriormente, a realização de uma prótese facial. Conclusão: O tratamento reabilitador com próteses obturadoras possui um bom resultado estético e funcional, favorecendo uma melhor função mastigatória e fonética, e melhorando consideravelmente a condição psicológica que é muito afetada nos pacientes submetidos a maxilectomia total ou parcial, sendo necessário uma boa interação com toda a equipe multiprofissional envolvida para que haja um melhor tratamento integrado para a reabilitação e melhora da qualidade de vida(AU)

Introduction: The treatment of malignant or benign tumors can result in surgical procedures, such as partial or total maxillectomy, generating oral communication in patients. One way to resolve these maxillofacial changes is through rehabilitative treatment with obturator prostheses in order to reestablish masticatory, aesthetic, phonetic and psychological function. Objective: the objective of this work was to report the clinical case of a cancer patient who was rehabilitated with an obturator prosthesis due to maxillectomy for malignant neoplasia of the maxillary sinus. Case report: A 62-year-old male patient sought dental care at the Oral Oncology Center of the Universidade Estadual Paulista "Júlio de Mesquita Filho" (UNESP) in Araçatuba ­ SP after undergoing a partial maxillectomy with oral cavity and was referred for the Specialization Course in Dental Prosthesis at the Faculty of Dentistry ­ Unesp/Araçatuba-SP for rehabilitation. It was proposed, firstly, to create an obturator prosthesis to close the bucosinusal communication and a total lower prosthesis for the antagonistic arch and, later, to create a facial prosthesis. Conclusion: Rehabilitative treatment with obturator prostheses has a good aesthetic and functional result, favoring better chewing and phonetic function, and considerably improving the psychological condition that is greatly affected in patients undergoing total or partial maxillectomy, requiring good interaction with the entire the multidisciplinary team involved so that there is better integrated treatment for rehabilitation and improved quality of life

Hipertensión pulmonar y leiomiomas uterinos, ¿existe relación causal? Serie de casos y revisión fisiopatológica / Pulmonary Hypertension and Uterine Leiomyomas, Is there a Causal Relationship? Case Series and Pathophysiological Review

Introducción: Los leiomiomas uterinos son un tipo de neoplasia benigna de frecuente aparición en mujeres de edad reproductiva, relacionados con enfermedad tromboem- bólica venosa. Este vínculo surge del efecto producido por la compresión de fibromas que genera estasis venosa en la región pelviana. Sin embargo, este pareciera no ser el único factor que lo relaciona con el desarrollo posterior de hipertensión pulmonar, sino que su presencia es gatillo de una serie de fenómenos que influyen sobre la vasculatu - ra pulmonar y también a nivel sistémico. Método: Revisión de una serie de casos (seis) atendidos en nuestra unidad, seguido de una revisión sobre la relación entre leiomio- mas y distintas formas de hipertensión pulmonar con una revisión desde la fisiopatología. Resultado y conclusiones: Encontramos sustento bibliográfico en los múltiples caminos fisiopatológicos que relacionan los mediadores vasculares comunes, que parecieran ser el punto clave en la relación entre estas dos patologías.

Introduction: Uterine leiomyomas are a type of benign neoplasm that frequently appears in women of reproductive age, related to venous thromboembolic disease. This link arises from the effect produced by the compression of fibroids, which generates venous stasis in the pelvic region. However, this seems not to be the only factor that re- lates it to the subsequent development of pulmonary hypertension, but rather its presence is a trigger for a series of phenomena that influence the pulmonary vasculature and also at a systemic level. Method: Review of a series of cases (six) cared for in our unit, followed by a review on the relationship between leiomyomas and different forms of pulmonary hypertension with a review from the pathophysiology. Result and conclusions: We found bibliographic support in the multiple pathophysiological paths that relate the common vascular mediators, which appear to be the key point in the relationship between these two pathologies.

Criopreservação de células-tronco mesenquimais do tecido adiposo: Uma alternativa para lipoenxertia seriada na reconstrução mamária / Cryopreservation of adipose tissue-derived mesenchymal stem cells: An alternative to serial fat grafting in breast reconstruction

Introdução: A lipoenxertia é um enxerto autólogo de células do tecido celular subcutâneo, que pode ser utilizada como técnica complementar na reconstrução mamária. Diante disso, a criopreservação de células-tronco mesenquimais provenientes de tecido adiposo (CTDAs) poderia ser uma maneira de realizar a coleta em um tempo cirúrgico e após realizar a lipoenxertia de forma fracionada. O dimetilsulfóxido (DMSO) é um criopreservante utilizado em pesquisas com células, porém é potencialmente tóxico, o que impossibilitaria a utilização de CTDAs criopreservadas na prática clínica. Novos criopreservantes celulares, sem toxicidade, vêm sendo descritos na literatura científica experimental, como as substâncias L-prolina e trealose. Com isso, esse trabalho teve como objetivo avaliar a viabilidade de CTDAs criopreservadas com a combinação de L-prolina e trealose, em um período de até 90 dias. Método: Estudo experimental, no qual foram obtidas amostras de lipoaspirado provenientes de 9 pacientes. A fração celular foi processada e congelada com L-prolina (1,5M) + trealose (0,2M), ou com DMSO + soro fetal bovino (SFB), como controle. Após 30 e 90 dias, as amostras foram descongeladas e a viabilidade celular foi avaliada pela técnica de MTT. Resultados: A análise das CTDAs, após 1 e 3 meses de congelamento, indicou que as amostras tratadas com L-prolina + trealose apresentaram viabilidade semelhante àquelas preservadas com DMSO e SFB (p=0,444). Conclusão: A associação de L-prolina e trealose manteve CTDA viáveis por 30 e 90 dias de congelamento, podendo ser uma alternativa como criopreservante celular sem toxicidade e viabilizando o uso de lipoenxertia seriada.

Introduction: Fat grafting is an autologous graft of cells from subcutaneous tissue, which can be used as a complementary technique in breast reconstruction. Given this, the cryopreservation of adipose tissue-derived mesenchymal stem cells (ADMSCs) could be a way to collect them in one surgical procedure and after performing fractional fat grafting. Dimethyl sulfoxide (DMSO) is a cryopreservative used in cell research, but it is potentially toxic, which would make it impossible to use cryopreserved ADMSCs in clinical practice. New cellular cryopreservatives, without toxicity, have been described in the experimental scientific literature, such as the substances L-proline and trehalose. Therefore, this work aimed to evaluate the viability of ADMSCs cryopreserved with the combination of L-proline and trehalose over up to 90 days. Method: Experimental study in which lipoaspirate samples were obtained from 9 patients. The cellular fraction was processed and frozen with L-proline (1.5M) + trehalose (0.2M) or with DMSO + fetal bovine serum (FBS) as control. After 30 and 90 days, the samples were thawed, and cell viability was assessed using the MTT technique. Results: The analysis of ADMSCs, after 1 and 3 months of freezing, indicated that samples treated with L-proline + trehalose showed similar viability to those preserved with DMSO and SFB (p=0.444). Conclusion: The association of L-proline and trehalose kept ADMSC viable for 30 and 90 days of freezing, and could be an alternative as a cellular cryopreservative without toxicity and enabling the use of serial fat grafting.

Objetivo: Comparar o desempenho funcional e as alterações cinemáticas da marcha em idosos saudáveis e em idosos com manifestações da síndrome da fragilidade, viventes na comunidade. Métodos: Estudo transversal do tipo caso-controle. Participaram do estudo 15 idosos, viventes na comunidade, separados em dois grupos, de acordo com a presença de manifestações de fragilidade: (n = 10) e controle (n = 5). Foram coletados dados sobre desempenho funcional, capacidade aeróbia, presença da síndrome da fragilidade e avaliação cinemática da marcha. Foram utilizados testes como: TC400m, dinamometria e SPPB. Para a análise de dados, foi utilizado o pacote estastístico PASW 18.0 (SPSS inc). Resultados: O tempo no teste de caminhada de 400m foi 11 segundos maior no grupo com sinais de fragilidade (p = 0,03), e a força de preensão palmar foi 25,8% maior no grupo sem fragilidade (p = 0,01). Conclusão: Concluimos que idosos frágeis possuem declínio no desempenho funcional em testes que avaliam a resistência aeróbia e a força muscular.

Objective: To compare functional performance and kinematic gait abnormalities in healthy elderly people and in elderly people with manifestations of the frailty syndrome, living in the community. Methods: A cross-sectional case-control study. Fifteen elderly people, living in the community, participated in the study. They were separated into two groups, according to the presence of manifestations of frailty (n = 10) and control (n = 5). Data on functional performance, aerobic capacity, presence of frailty syndrome, and kinematic gait assessment were collected. Tests, such as: TC400m, dynamometry, and SPPB were used. For data analysis, the statistical package PASW 18.0 (SPSS inc) was used. Results: The time in the 400m walk test was 11 seconds higher in the group with signs of frailty (p = 0.03), and handgrip strength was 25.8% higher in the group without frailty (p = 0.01). Conclusion: We conclude that frail elderly people have a decline in functional performance in tests that assess aerobic resistance and muscle strength.

Epidemiological and clinical study of cases of endemic pemphigus foliaceus and pemphigus vulgaris in a reference center in the state of Minas Gerais, Brazil

Abstract Background: Pemphigus constitutes a group of autoimmune bullous diseases. A reduction in the incidence of endemic pemphigus foliaceus and an increase in pemphigus vulgaris has been described, but there are no studies in Minas Gerais that address the subject. Objective: To describe the epidemiological and clinical profile of patients with pemphigus treated at the Dermatology Service of a public University Hospital in the state of Minas Gerais, Brazil. Methods: An observational, descriptive, and cross-sectional study was carried out of cases of endemic pemphigus foliaceus and pemphigus vulgaris, for a period of six months. A questionnaire was filled out with epidemiological and clinical data on the disease. Results: A total of 122 patients were included in the study, 64 with endemic pemphigus foliaceus and 58 with pemphigus vulgaris. When comparing patients with endemic pemphigus foliaceus and those with pemphigus vulgaris, a statistical difference was observed between the median age of initial disease manifestation (p = 0.001), patient occupation (p = 0.010), area of residence (p = 0.000), forests (p = 0.000) and rivers/streams close to the dwelling (p = 0.001) and the number of systemic medications required to control the disease (p = 0.002). When comparing patients with endemic pemphigus foliaceus to those evaluated in a study carried out at the same service in 2008, there was a statistical difference in the area of residence (p = 0.030). Study limitations: The assessed population comes from a tertiary care service that is not a reference for the entire state. Conclusions: Patients with endemic pemphigus foliaceus and pemphigus vulgaris maintain statistically significant differences regarding their main variables in the literature, such as age and area of residence. Historically, there has been a reduction in cases of endemic pemphigus foliaceus and an increase in cases of pemphigus vulgaris in this population.

Aplicabilidad del índice de fragilidad hepática en pacientes cirróticos evaluados para trasplante / Applicability of the liver frailty index in cirrhotic patients evaluated for transplantation

Introducción. En las últimas décadas se han desarrollado diferentes scores y modelos para predecir el pronóstico en pacientes con enfermedad hepática crónica avanzada. Los más reconocidos y utilizados son el sistema de estadificación de Child-Pugh (CP) y el score de MELD, pero estos carecen de herramientas para evaluar objetivamente otros factores pronósticos. Por este motivo, se ha incorporado el concepto de fragilidad a la hepatología clínica. El objetivo de este artículo es examinar la aplicabilidad del índice de fragilidad hepática (IFH) en pacientes con cirrosis evaluados para trasplante hepático en Uruguay. Metodología. Estudio observacional, descriptivo y retrospectivo en el Servicio de Enfermedades Hepáticas del Hospital Central de las Fuerzas Armadas (HCFFAA) de enero de 2018 a diciembre de 2021. Resultados. Se evaluaron un total de 78 pacientes, excluyéndose 19 de estos, culminando con una muestra final de 59 pacientes. La edad media fue de 52 años, siendo el 66 % hombres. La principal etiología de la cirrosis fue la alcohólica, y la comorbilidad más frecuente fue el sobrepeso/obesidad (66 %). La media de IFH fue de 4,03 ± 0,45. El 90 % de los pacientes eran prefrágiles, el 10 % frágiles y ningún paciente fue clasificado como no frágil. El 76 % presentaba un estadio avanzado de la enfermedad al momento de la evaluación 42 % CP estadio B, 34 % CP C, 24 % CP A, con una media de MELD-Na de 17,8 ± 7,6. El 17 % tuvo complicaciones infecciosas. La mortalidad global (n=78) fue del 12 %, y la de los pacientes con IFH calculado fue del 22 %. Conclusiones. El cálculo del IFH es realizable en cirróticos como herramienta objetiva que brinda una mirada integral del paciente. A mayor severidad de la cirrosis, mayor es el IFH. Sin embargo, este índice no parece ser un predictor de la eventual realización del trasplante hepático, ni de muerte en lista de espera en nuestros pacientes.

Introduction. In recent decades, several scores and models have been proposed to predict prognosis in patients with advanced chronic liver disease. The most recognized and used are the Child-Pugh (CP) and the Model for End-stage Liver Disease (MELD) scores, but they lack tools to objectively evaluate other prognostic factors. For this reason, the concept of fragility has been incorporated into clinical hepatology. The objective of this study was to evaluate the applicability of the liver frailty index (LFI) in patients with cirrhosis evaluated for liver transplantation in Uruguay. Methodology. Observational, descriptive and retrospective study at the Hospital Central de las Fuerzas Armadas (HCFFAA) Liver Disease Service from January 2018 to December 2021. Results. A total of 78 patients were evaluated, 19 were excluded, culminating in a final sample of 59 patients. The mean age was 52 years, with 66% being men. The main etiology of cirrhosis was alcoholic and the most frequent comorbidity was overweight/obesity (66%). The mean LFI was 4.03 ± 0.45. 90% of patients were pre-fragile, 10% were fragile, and no patient was classified as non-fragile. 76% had an advanced stage of the disease at the time of evaluation: 42% CP stage B, 34% CP C, 24% CP A, with a mean MELD-Na of 17.8 ± 7.6. 17% had infectious complications. Overall mortality (n=78) was 12%, and that of patients with calculated LFI was 22%. Conclusions. The LFI can be calculated in cirrhotic patients, and it is an objective tool that provides a comprehensive view of the patient. LFI depends on the severity of the cirrhosis. However, this index is not a predictor of liver transplantation or death on the waiting list in our patients.

Mortalidad intrahospitalaria de pacientes con COVID-19 complicados con neumonías bacterianas en asistencia respiratoria mecánica en Cuidados Intensivos de Adultos en un Hospital del Paraguay / In-hospital mortality of patients with COVID-19 complicated by bacterial pneumonia on mechanical ventilation in Adult Intensive Care in a Hospital in Paraguay

Introducción: los pacientes con COVID-19 ingresan en mayor proporción a asistencia respiratoria mecánica, aumentando: el riesgo de neumonía asociada a ventilador (NAV) las tasas de mortalidad, los días de permanencia en las unidades de terapia intensiva (UCI) y los costos sanitarios. Objetivo: determinar la Mortalidad intrahospitalaria de pacientes con COVID-19 complicados con neumonías bacterianas en asistencia respiratoria mecánica en Cuidados Intensivos de Adultos en un Hospital del Paraguay durante los años 2020 a 2021. Metodología: estudio analítico de tipo cohorte retrospectiva. Se registraron variables demográficas, comorbilidades, puntajes en scores de gravedad como el APACHE II al ingreso, la cifra más baja de oxigenación durante la internación expresado por la PaO2 / FIO2, días de ventilación, colocación en decúbito prono, traqueotomía, medidas terapéuticas farmacológicas y no farmacológicas, días de internación, así como las complicaciones y la mortalidad. Resultados: fueron incluidos 214 pacientes, 135 ingresaron a asistencia respiratoria mecánica (ARM) de los cuales 58 (42,9 %) desarrollaron NAV, con edad mediana de 52 años (40-60). Los microorganismos de NAV fueron cocos Gram negativos en 98,3 %, incluyendo Acinetobacter baumanii en 46,5 %, Klebsiella pneumoniae en 22,8 %, Pseudomona aeruginosa en 15,5 % y 5,2 % Stenotrophomona maltofilia. La mortalidad intrahospitalaria fue del 44,8 %. Los menores de 50 años tienen una sobrevida mayor que los mayores (34 días vs 22 días, con p de 0,026). Conclusión: la mortalidad intrahospitalaria fue del 44,8 %. La edad fue un factor de riesgo independiente para la mortalidad en pacientes con NAV, por lo que los profesionales de la salud deben estar atentos a la posibilidad de NAV en pacientes que requieren asistencia respiratoria mecánica, especialmente en pacientes mayores de 50 años.

Introduction: patients with COVID-19 are more likely to require mechanical ventilation, which increases the risk of ventilator-associated pneumonia (VAP), mortality rates, length of stay in intensive care units (ICUs), and healthcare costs. Objective: to determine the in-hospital mortality of patients with COVID-19 complicated by bacterial pneumonia on mechanical ventilation in Adult Intensive Care in a Hospital in Paraguay during the years 2020 to 2021. Methodology: this is a retrospective cohort analytical study. Demographic variables, comorbidities, severity scores such as APACHE II on admission, the worst oxygenation during hospitalization expressed by PaO2/FiO2, days of ventilation, prone position, tracheostomy, pharmacological and non-pharmacological therapeutic measures, days of hospitalization, as well as complications and mortality were recorded. Results: a total of 214 patients were included, 135 were admitted to mechanical ventilation (MRA), of which 58 (42.9%) developed VAP, with a median age of 52 years (40-60). VAP microorganisms were Gram-negative cocci in 98.3%, including Acinetobacter baumanii in 46.5%, Klebsiella pneumoniae in 22.8%, Pseudomona aeruginosa in 15.5%, and Stenotrophomona maltophilia in 5.2%. In-hospital mortality was 44.8%. Those under 50 years of age have a longer survival than those older (34 days vs. 22 days, with p of 0.026). Conclusion: the overall mortality rate was 44.8%. Age was an independent risk factor for mortality in patients with VAP, so healthcare professionals should be aware of the possibility of VAP in patients who require mechanical ventilation, especially in patients over 50 years of age.

Inibidores BTK e BCL-2 no Tratamento de Primeira Linha da Leucemia Linfocítica Crônica em Pacientes de Alto Risco: Revisão Sistemática e Meta-Análise em Rede / BTK and BCL-2 Inhibitors in the First-Line Treatment of Chronic Lymphocytic Leukemia in High-Risk Patients: Systematic Review and Network Meta-Analysis / Inhibidores de BTK Y BCL-2 en el Tratamiento de Primera Línea de la Leucemia Linfocítica Crónica en Pacientes de Alto Riesgo: Revisión Sistemática y un Metaanálisis en Red

Introdução: Pacientes com leucemia linfocítica crônica (LLC) com alto risco têm menores taxas de resposta, curso clínico mais agressivo e resistência à quimioterapia padrão, representando um desafio para o tratamento. Os inibidores da tirosina quinase de Bruton (BTK ­ ibrutinibe e acalabrutinibe) e o inibidor BCL-2 (venetoclax) podem ser utilizados nesses casos. Objetivo: Identificar e avaliar a eficácia e a segurança do uso de ibrutinibe, acalabrutinibe e venetoclax no tratamento de primeira linha em pacientes com LLC de alto risco. Método: Revisão sistemática de ensaios clínicos randomizados que avaliaram pacientes adultos com LLC, portadores de deleção 17p ou mutação TP53 e sem tratamento prévio. Foram pesquisadas as bases PubMed, EMBASE, LILACS e Cochrane Library, e realizadas avaliação do risco de viés pela ferramenta RoB 2 da Cochrane e avaliação da qualidade da evidência pelo GRADE. Resultados: Na meta-análise em rede para sobrevida livre de progressão (SLP), venetoclax + obinutuzumabe (RR: 0,62; IC 95% 0,41-0,95; p = 0,027) e acalabrutinibe + obinutuzumabe (RR: 0,74; IC 95% 0,55-0,99; p = 0,043) apresentaram menor risco de progressão ou óbito, com significância considerada limítrofe. Ibrutinibe + obinutuzumabe (RR: 0,93; IC 95% 0,86-1,00; p = 0,054) não apresentou diferença significativa na SLP para pacientes com LLC de alto risco. Conclusão: O tratamento de primeira linha com inibidores de BTK (ibrutinibe e acalabrutinibe) e o inibidor BCL-2 (venetoclax), associados a agentes monoclonais anti-CD20 ­ especialmente o obinutuzumabe ­, tem sido proposto como padrão para a maioria dos pacientes com LLC. Entretanto, pelos resultados desta revisão com meta-análise em rede, não foi possível confirmar essa recomendação.

Introduction: Patients with high-risk chronic lymphocytic leukemia (CLL) have lower response rates, a more aggressive clinical course, and resistance to standard chemotherapy, representing a treatment challenge. Bruton's tyrosine kinase inhibitors (BTK ­ ibrutinib and acalabrutinib) and the BCL-2 inhibitor (venetoclax) can be used in these cases. Objective: To identify and evaluate studies on the efficacy and safety of the use of ibrutinib, acalabrutinib and venetoclax in first-line treatment in patients with high-risk CLL. Method:Systematic review of randomized clinical trials that evaluated adult patients with CLL, carriers of 17p deletion or TP53 mutation and without prior treatment. The PubMed, EMBASE, LILACS and Cochrane Library databases were searched, and the risk of bias was assessed using the Cochrane RoB 2 tool and the quality of evidence was assessed with GRADE. Results: In the network meta-analysis for progression-free survival (PFS) venetoclax + obinutuzumab (RR: 0.62; 95%CI 0.41-0.95; p value 0.027) and acalabrutinib + obinutuzumab (RR: 0. 74; 95% CI 0.55-0.99; p value 0.043) presented a lower risk of progression or death, with significance considered borderline. Ibrutinib + obinutuzumab (RR: 0.93; 95% CI 0.86-1.00; p value 0.054) did not show a significant difference in PFS for patients with high-risk CLL. Conclusion: First-line treatment with BTK inhibitors (ibrutinib and acalabrutinib) and the BCL-2 inhibitor (venetoclax) associated with anti-CD20 monoclonal agents ­ especially obinutuzumab ­ have been proposed as the standard for most patients with CLL. However, based on the results of this review with network meta-analysis, it was not possible to confirm this recommendation.

Effectiveness of Tocilizumab in COVID-19 patients with pneumonia: A systematic review

Background and Objective@#COVID-19 contributes significantly to global morbidity and mortality. Age-related comorbidities elevate the risk of severe cases. Studies have recently demonstrated that widely available medications, including tocilizumab (TCZ), can manage severe symptoms. However, its effectiveness is unclear, particularly among the older population. Therefore, this review aimed to evaluate TCZ’s efficacy in managing severe pneumonia in individuals aged 50 and older.@*Methods@#We systematically search several databases and gray literature including Web of Science, CINAHL, Academic Search Complete, PsycINFO, PsycArticles, SocINDEX, CENTRAL/Cochrane Library, PubMed/MEDLINE for original research articles in English across several study designs published in the year 2020-2022. A narrative synthesis was conducted to summarize the evidence. We employed the NIH quality assessment tool for observational cohort studies to evaluate risk of bias. Additionally, we utilized GRADE to appraise the certainty of evidence.@*Results@#Among 539 screened articles, only five studies met the selection criteria. Tocilizumab's impact on severe COVID-19 pneumonia revealed a diverse effect on mortality rate, with 29% in the TCZ group, and 40% in the controls died within 30 days of intubation (OR 0.61; 95% CI, 0.27-1.36). It is also reported that TCZ was not associated with mortality, despite faster decline in pulmonary function and prolonged fever. Hospital mortality in the TCZ group was significantly lower than in the controls, and age over 60 was the only significant risk factor. Moreover, administering TCZ reduced mechanical ventilation needs, with 82% extubated compared to 53% in controls. However, 45% in TCZ group was associated with a higher ventilator-associated pneumonia rate than in the untreated group which was 20% (P < 0.001). Despite this, TCZ-treated patients had shorter hospital stays.@*Conclusions@#The effects of tocilizumab on reducing mortality risk and improving the survival rate of COVID-19 patients with pneumonia remained inconclusive. Yet, the majority of results suggested that giving tocilizumab leads to shorter hospital stays, lowers the requirement for mechanical ventilation, and decreases the likelihood of ICU transfer. Tocilizumab is linked to the incidence of secondary infections; hence, this medication should be closely monitored for side effects.

Long-term outcomes of intraoperative triamcinolone injection versus postoperative oral prednisolone in congenital cataract surgery / Resultados de longo prazo do uso intraoperatório de triancinolona versus oral pós-operatório de prednisolona na cirurgia de catarata congênita

ABSTRACT Purpose: To compare the long-term ocular findings of children that were operated of congenital cataract before the age of two and that received an intraoperative intracameral triamcinolone injection or used postoperative oral prednisolone to modulate ocular inflammation. Methods: All patients who had previously participated in a clinical trial that analyzed the 1-year surgical outcomes of congenital cataract surgery utilizing intracameral triamcinolone (study group) or oral prednisolone (control group) were eligible to participate in this prospective cohort research. Patients' medical records were reviewed, and the children underwent a complete ophthalmologic exam on final follow-up. Biomicroscopic findings, intraocular pressure, central corneal thickness, the need for additional surgical interventions, and findings compatible with glaucoma were the primary end measures. Results: Twenty-six eyes (26 patients) were included (study group = 11 eyes; control group = 15 eyes). The mean follow--up was 8.2 ± 1.2 years and 8.1 ± 1.7 years in the study and control groups, respectively (p=0.82). All eyes presented a centered intraocular lens. There was no statistically significant difference between the groups with regards to the presence of posterior synechia (p=0.56), intraocular pressure (p=0.49), or central corneal thickness (p=0.21). None of the eyes fulfilled the glaucoma diagnostic criteria, presented secondary visual axis obscuration, or were reoperated. Conclusion: The long--term ocular findings of children that underwent congenital cataract surgery and received an intraoperative intracameral triamcinolone injection were similar to those that used postoperative oral prednisolone to modulate ocular inflammation. This suggests that intracameral triamcinolone may substitute oral prednisolone in congenital cataract surgery, facilitating the postoperative treatment regimen and compliance.

RESUMO Objetivo: Comparar os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita antes dos dois anos de idade e receberam uma injeção intracameral de triancinolona no intraoperatório ou usaram prednisolona oral no pós-operatório para modular a inflamação ocular. Métodos: Neste estudo prospectivo de coorte, todos os pacientes que participaram de um ensaio clínico anterior, que analisou os resultados cirúrgicos de 1 ano da cirurgia de catarata congênita usando triancinolona intracameral (Grupo de Estudo) ou prednisolona oral (Grupo Controle), eram elegíveis para participar. Os prontuários médicos dos pacientes foram revisados e as crianças foram submetidas a um exame oftalmológico completo no acompanhamento final. As principais medidas de desfecho foram: achados biomicroscópicos, pressão intraocular, espessura central da córnea, a necessidade de intervenções cirúrgicas adicionais e achados compatíveis com glaucoma. Resultados: Vinte e seis olhos (26 pacientes) foram incluídos (Grupo de Estudo = 11 olhos; Grupo de Controle = 15 olhos). O seguimento médio foi de 8,2 ± 1,2 anos e 8,1 ± 1,7 anos nos Grupos de Estudo e Controle, respectivamente (p=0,82). Todos os olhos apresentavam lente intraocular centrada. Não houve diferença estatisticamente significativa entre os grupos com relação à presença de sinéquia posterior (p=0,56), pressão intraocular (p=0,49) ou espessura central da córnea (p=0,21). Nenhum dos olhos preencheu os critérios diagnósticos para glaucoma, apresentou opacificação secundária do eixo visual ou foi reoperado. Conclusão: Os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita e receberam uma injeção intracameral de triancinolona no intraoperatório foram semelhantes aos que usaram prednisolona oral no pós-operatório para modular a inflamação ocular, sugerindo que a triancinolona intracameral pode substituir a prednisolona oral na cirurgia de catarata congênita, facilitando o tratamento pós-operatório e a adesão ao mesmo.
