ABSTRACT

ABSTRACT Introduction Core strength training is essential for maintaining postural stability and explosive movement support, typical of tennis players. It has been proven that core strength training improves the motor coordination of the athlete's whole body. Therefore, it is essential to develop specific approaches to strengthen the core in tennis players. Objective Analyze the effect of core strength training in college tennis players. Methods Twenty college tennis players were selected and randomly divided into two groups: core strength training and general training. Comparative results of the experiment were statistically processed for analysis on the effect of core strength training versus general strength training. Results There is a big difference in the level of fitness indicators before and after 14 weeks of core strength training (P < 0.05). The average gain in training speed of the athletes in the experimental group was 8.24% versus 1.05% in the control group. Conclusion Core strength training can improve the physical fitness of tennis players. Complementary core strengthening training can favor performance in matches and competition results. Evidence level II; Therapeutic Studies - Investigating the results.

ABSTRACT

Objetivos: estabelecer diagnóstico diferencial das demências em ambulatório de geriatria no Distrito Federal, calculando-se sua prevalência por meio de exame clínico e avaliação multifuncional. Método: estudo longitudinal, retrospectivo, com amostra de pessoas com 60 anos ou mais residentes no Distrito Federal-Brasil, com déficit cognitivo caracterizado por Transtorno Neurocognitivo (TNC) Maior (demência), cadastradas durante os anos de 2010 a 2018. A coleta de dados foi realizada em prontuários para selecionar e avaliar o perfil do idoso com diagnóstico de TNC seguida de avaliação geriátrica ampla e avaliação multifuncional. A análise de dados foi realizada com o cálculo da prevalência, estatística descritiva e índice V de Cramer. Resultados: 158 indivíduos conseguiram concluir todas as avalições. 52,5% possuem de 80 a 89 anos, 62,5% são mulheres e 62,7% caucasianos, 50,6% viúvos e 47,5% analfabetos. A prevalência inicial de Doença de Alzheimer (DA) foi de 45,6%, reduzindo-se para 35,4% após um período de acompanhamento e a demência vascular (DV) foi de 34,2%, inicialmente, e 45,6% ao final. Utilizou-se o Coeficiente V de Cramer, em que se encontrou uma relação fraca de fatores de risco com os diagnósticos das demências apresentados. Conclusão: DV foi a mais prevalente na área estudada. Entende-se ser a maior frequência de DA esteja relacionada à avaliação superficial uma vez que esse tipo de demência é mundialmente mais frequente

ABSTRACT

Aim: This study aimed to evaluate the effect of frozen storage on the physical properties of a silicone-based test food material, highly used to evaluate the masticatory performance in research settings. Methods: A total of 1,666 silicone cubes of Optosil Comfort® with 5.6-mm edges were shaped and stored at -18°C. The cubes were subsequently tested for flexural strength (maximum force, displacement, stress, and strain) before breaking (n = 136), changes in weight and size (n = 170), and masticatory performance (n = 1360) at eight timepoints: immediately after cube preparation (baseline, no freezing), and 1, 2, 3 and 4 weeks, and 2, 4 and 6 months after frozen storage. The cubes were thawed 8 h before each assessment. Results: The maximum force, stress, maximum displacement, and deformation values for the cubes were not affected by freezing (P > 0.05). At all of the time points, the cubes exhibited similar weight (P = 0.366) and size (identical values). The masticatory performance for the cubes also showed no differences from baseline through 6 months (P = 0.061). Conclusion: Freezing Optosil Comfort® silicone cubes did not alter the physical and mechanical properties of the material, being suitable to optimize the assessment of masticatory parameters for research purposes

ABSTRACT

Abstract Introduction: Most successful cases of COVID-19 pandemic mitigation and handling have relied on extensive reverse-transcription quantitative polymerase chain reaction (RT-qPCR). However, many emerging economies have struggled with current molecular testing demands due to economic, technical and technological constraints. Objective: To define a potential diagnostic protocol to increase testing capacity in current and post-pandemic conditions. Methods: We reviewed the literature, patents and commercial applications, for alternatives. Results: We found a good potential in saliva samples, viral inactivation and quick RNA extraction by heating; the use of an isothermal technology such as loop mediated isothermal amplification (LAMP) and naked eye test-result visualization by in-tube colorimetry or turbidity. Conclusions: Saliva samples with quick RNA extraction by heating and colorimetric LAMP are promising options for countries with economic and infrastructure limitations.

ABSTRACT

Resumen Introducción: La naturaleza tropical está experimentando una amenaza sin precedentes que incluye comunidades de peces costeros que requieren un constante seguimiento de la presencia de especies. El uso simultáneo de varios métodos de monitoreo debería reducir el sesgo causado por la selectividad de cada método. Objetivo: Este estudio uso cuatro diferentes métodos de muestreo a lo largo de dos años para evaluar y comparar los ensamblajes de peces en el Área Marina de Manejo Bahía Santa Elena, Pacífico de Costa Rica. Métodos: Examinamos los cambios en la riqueza y composición de especies entre épocas de afloramiento y no afloramiento entre julio de 2019 y febrero de 2020. Aplicamos censos visuales, cámaras remotas submarinas; líneas de fondo; y pesca deportiva. Resultados: Identificamos 140 especies de peces (54 familias); las cámaras submarinas remotas detectaron el 83 %, seguido por los censos visuales submarinos (65 %), la pesca deportiva (16 %) y las líneas de fondo (14 %). Solo el método de pesca deportiva detectó diferencias en la riqueza y composición de especies entre temporadas. Conclusión: Las cámaras remotas parecen ser el mejor método para el conteo de especies y la pesca deportiva para detectar diferencias estacionales en las costas tropicales similares a la aquí estudiada.


Abstract Introduction: Tropical nature is experiencing an unprecedented threat that includes coastal fish communities that requires a close monitoring of species presence. The simultaneous use of several monitoring methods should reduce the bias caused by the selectivity of each method. Objective: This study used four different sampling methods over two years to assess and compare fish assemblages in the Santa Elena Bay Marine Management Area (AMM-BSE), North Pacific of Costa Rica. Methods: We examined changes in species richness and composition between upwelling and non-upwelling seasons from July 2019 and February 2020. We applied visual censuses, underwater remote cameras; bottom lines; and sport fishing. Results: We identified 140 species of fish (54 families); remote underwater cameras detected 83 %, followed by underwater visual censuses (65 %), sport-fishing (16 %) and bottom lines (14 %). Only the sport-fishing method detected differences in species richness and composition between seasons. Conclusion: Remote cameras appear to be the best method for species counts, and sport-fishing to detect seasonal differences in tropical coasts similar to the one studied here.

ABSTRACT

La atresia de coanas se caracteriza por la obliteración de la abertura nasal posterior. Es la anomalía congénita más frecuente de las fosas nasales. Tiene una incidencia de 1 cada 5000 a 7000 neonatos, con predominio en el sexo femenino. Puede presentarse en forma aislada o asociada a otros síndromes como el CHARGE (coloboma [C], malformaciones cardíacas [H], atresia de coanas [A], retraso psicomotor y/o en el crecimiento [R], hipoplasia de genitales [G], malformaciones auriculares y/o sordera [E, por su sigla en inglés]). Las manifestaciones clínicas son la obstrucción nasal, cianosis y dificultad respiratoria desde el nacimiento cuando es bilateral. Las atresias unilaterales se caracterizan por insuficiencia ventilatoria nasal y rinorrea unilateral, y pueden pasar inadvertidas. El diagnóstico se realiza mediante endoscopia y estudios por imágenes. El tratamiento es quirúrgico; existen diferentes técnicas y vías de abordaje. Se presenta el caso de un paciente masculino de 7 años con atresia unilateral de coana derecha con resolución microendoscópica, colocación de tutor externo, con buena resolución.


Choanal atresia is characterized by obliteration of the posterior nasal opening. It is the most common congenital anomaly of the nasal passages. It has an incidence of 1 in 5000 to 7000 newborns; predominantly female. It can occur in isolation or in association with other syndromes such as CHARGE (coloboma [C], cardiac malformations [H], choanal atresia [A], psychomotor and/or growth retardation [R], genital hypoplasia [G], atrial malformations and/or deafness [E]. Clinicallypresents nasal obstruction, cyanosis and respiratory distress from birth when bilateral, unilateral atresias are characterized by nasal ventilatory insufficiency and unilateral rhinorrhea, which may go unnoticed. Diagnosis is made by endoscopy and imaging tests. Treatment is surgical, with different techniques and approaches.A 7-year-old male patient is presented with unilateral atresia of the right choana with microendoscopic resolution, placement of an external tutor, with good resolution.

ABSTRACT

Abstract Ischemic strokes secondary to occlusion of large vessels have been described in patients with COVID-19. Also, venous thrombosis and pulmonary thromboembolism have been related to the disease. Vascular occlusion may be associated with a prothrombotic state due to COVID-19-related coagulopathy and endotheliopathy. Intracranial hemorrhagic lesions can additionally be seen in these patients. The causative mechanism of hemorrhage could be associated with anticoagulant therapy or factors such as coagulopathy and endotheliopathy. We report on cases of ischemic, thrombotic, and hemorrhagic complications in six patients diagnosed with SARS-CoV-2 infection. Chest computed tomography (CT) showed typical SARS-CoV-2 pneumonia findings in all the cases, which were all confirmed by either serology or reverse transcription polymerase chain reaction (RT-PCR) tests.

ABSTRACT

El adenocarcinoma pancreático ductal (APD) es la cuarta causa de muerte por cáncer y se proyecta que para el 2030 ocupe el segundo lugar. El pronóstico es sombrío, siendo la sobrevida menor a 9% en 5 años. Se consideró durante mucho tiempo a la resección quirúrgica como el único tratamiento curativo, sin embargo, sólo el 15 a 20% de los pacientes pueden ser beneficiados con la misma. La clasificación pre terapéutica más utilizada es la del National Comprehensive Cáncer Network (NCCN), basada en la relación del tumor con estructuras vasculares, clasificándolos en tumores "resecables", de resección límite "Borderlines" y "localmente avanzados". Se presenta el primer caso registrado en Paraguay de APD con infiltración de la Vena Mesentérica Superior (VMS) tratado con duodenopancreatectomía cefálica (DPC) asociada a resección vascular mayor.


Pancreatic ductal adenocarcinoma (PDA) is the fourth leading cause of cancer death and is projected to rank second by 2030. The prognosis is bleak, with survival being less than 9% in 5 years. For a long time, surgical resection was considered the only curative treatment, however, only 15 to 20% of patients can benefit from it. The most widely used pre-therapeutic classification is that of the National Comprehensive Cancer Network (NCCN), based on the relationship of the tumor with vascular structures, classifying them into "resectable", "borderline" and "locally advanced" tumors. We present the first registered case in Paraguay of PDA with infiltration of the Superior Mesenteric Vein (SMV) treated with cephalic duodenopancreatectomy (CPD) associated with major vascular resection.

ABSTRACT

Este trabajo tuvo como objetivo conocer la fiabilidad de la impresora 3D (i3D) aditiva por Matriz de Proceso Digital de Luz (MDLP) Hellbot modelo Apolo®, a través de verificar la congruencia dimensional entre las mallas de modelos impresos (MMi) y su correspondiente archivo digital de origen (MMo), obtenido del software de planificación ortodontica Orchestrate 3D® (O3D). Para determinar su uso en odontología y sus posibilidades clínicas, fue comparada entre cinco i3D de manufactura aditiva, dos DLP, dos por estereolitografía (SLA) y una por Depósito de Material Fundido (FDM). La elección de las cinco i3D se fundamentó en su valor de mercado, intentando abarcar la mayor diversidad argentina disponible. Veinte modelos fueron impresos con cada i3D y escaneados con Escáner Intraoral (IOS) Carestream modelo 3600® (Cs3600). Las 120 MMi fueron importadas dentro del programa de ingeniería inversa Geomagic® Control X® (Cx) para su análisis 3D, consistiendo en la superposición de MMo con cada una de las MMi. Luego, una evaluación cualitativa de la desviación entre la MMi y MMo fue realizada. Un análisis estadístico cuidadoso fue realizado obteniendo como resultado comparaciones en 3d y 2d. Las coincidencias metrológicas en la superposición tridimensional permitieron un análisis exhaustivo y fácilmente reconocible a través de mapas colorimétricos. En el análisis bidimensional se plantearon planos referenciados dentariamente desde la MMo, para hacer coincidir las mediciones desde el mismo punto de partida dentaria. Los resultados fueron satisfactorios y muy alentadores. Las probabilidades de obtener rangos de variabilidad equivalentes a +/- 50µm fueron de un 40,35 % y de +/- 100µm un 71,04 %. Por lo tanto, te- niendo en cuenta las exigencias de congruencia dimensional clínicas de precisión y exactitud a las cuales es sometida nuestra profesión odontológica, se evitan problemas clínicos arrastrados por los errores dimensionales en la manufactura (Cam) (AU)


The objective of this study was to determine the reliability of the Hellbot Apollo® model additive 3D printer (i3D) by Matrix Digital Light Processing (MDLP) by verifying the dimensional congruence between the printed model meshes (MMi) and their corresponding digital source file (MMo), obtained from the Orchestrate 3D® (O3D) orthodontic planning software. A comparison was made between five i3D of additive manufacturing, two DLP, two by stereolithography (SLA), and one by Fused Material Deposition (FDM), to determine its use in dentistry and its clinical possibilities. The choice of the five i3D was based on their market value, trying to cover most of the Argentinean diversity available. Twenty models were printed with each i3D and scanned with Carestream Intraoral Scanner (IOS) model 3600® (Cs3600). The 120 MMi were imported into the reverse engineering program Geomagic® Control X® (Cx) for 3D analysis, consisting of overlaying MMo with each MMi. Then, a qualitative evaluation of the deviation between MMi and MMo. Also, a careful statistical analysis was performed, resulting in 3d and 2d comparisons. Metrological coincidences in three-dimensional overlay allowed a comprehensive and easily recognizable analysis through colorimetric maps. In the two-dimensional analysis, dentally referenced planes were proposed from the MMo, to match the measurements from the same dental starting point. The results were satisfactory and very encouraging. The probabilities of obtaining ranges of variability equivalent to +/- 50µm were 40.35 % and +/- 100µm 71.04 %. Therefore, considering the demands of clinical dimensional congruence, precision, and accuracy to which our dental profession it is subjected, clinical problems caused by dimensional errors in manufacturing (Cam) are avoided (AU)

ABSTRACT

El granuloma piógeno es una lesión benigna, reactiva y multifactorial que resulta de le- siones repetitivas, microtraumatismos e irritación local en piel o mucosas y cambio hormonal. Cuando aparece en la cavidad oral tiene predilección por la encía vestibular, pero es importante que el odontólogo esté consciente y familiarizado con el hecho de que puede estar localizado en otras áreas anatómicas. Clínicamente se presenta como lesión hiperplásica altamente vascularizada, de tamaño generalmente no mayor a 2 cm, pediculada en la base o sésil y de lento crecimiento. Sin mostrar preferencia por edad o sexo, tiende a aparecer principalmente en encías, labios y mucosa oral, siendo muy pocos los casos reportados en el área lingual. Es por ello que, en este artículo, nos referimos a un caso de ubicación inusual, en conjunto con una revisión de la literatura (AU)


Pyogenic granuloma is a benign, reactive, and multifactorial lesion caused by repetitive injuries, microtrauma and local irritation on the skin or mucous membranes, and hormonal change. When it appears in the oral cavity, it has a predilection for the vestibular gingiva, but the dentist must be aware and familiar with the fact that it can be present in other anatomi- cal areas. Clinically, it is presented as a hyperplasic injury highly vascular-related, with a size generally no bigger than 2 cm, pedunculated in base or sessile, and slow in growth. Without showing any preference in age or gender, it tends to appear mainly on the gums, lips, and oral mucosae, with very few, reported cases in the lingual area. Therefore, in this study, we refer to a case of unusual localization with a literature review (AU)

ABSTRACT

ABSTRACT BACKGROUND: Clinical assessment of head and neck cancers is highly challenging owing to the complexity of regional anatomy and wide range of lesions. The diagnostic evaluation includes detailed physical examination, biopsy and imaging modalities for disease extent and staging. Appropriate imaging is done to enable determination of precise tumor extent and involvement of lymph nodes, and detection of distant metastases and second primary tumors. OBJECTIVE: To evaluate the initial staging discrepancy between conventional contrasted computed tomography (CT) and 18F-fluorodeoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) and its impact on management plans for head and neck malignancies. DESIGN AND SETTING: Prospective cross-sectional study in two tertiary-level hospitals. METHODS: This study included 30 patients with primary head and neck malignant tumors who underwent contrasted computed tomography and whole-body 18F-FDG PET/CT assessments. The staging and treatment plans were compared with the incremental information obtained after 18F-FDG PET/CT. RESULTS: 18F-FDG PET/CT was found to raise the stage in 33.3% of the cases and the treatment intent was altered in 43.3% of them, while there was no management change in the remaining 56.7%. 18F-FDG PET/CT had higher sensitivity (96% versus 89.2%) and accuracy (93% versus 86.7%) than conventional contrast-enhanced computed tomography. CONCLUSION: Our study demonstrated that 18F-FDG PET/CT had higher sensitivity and accuracy for detecting head and neck malignancy, in comparison with conventional contrast-enhanced computed tomography. 18F-FDG PET/CT improved the initial staging and substantially impacted the management strategy for head and neck malignancies.

ABSTRACT

A obesidade é definida pelo excesso de gordura corporal acumulada no tecido adiposo quando o indivíduo atinge valores de IMC igual ou superior a 30 Kg/m2. Constitui um dos principais fatores de risco para várias doenças não transmissíveis (DNTs) como por exemplo, diabetes mellitus tipo 2 (DM2), doenças cardiovasculares, hipertensão arterial, acidente vascular cerebral e até mesmo o câncer. Embora a obesidade esteja diretamente relacionada com o consumo calórico excessivo em relação ao gasto energético diário, sua etiologia pode estar associada aos baixos níveis de atividade física, às alterações neuroendócrinas e aos fatores genéticos. Considerando o componente genético, esta pode ser classificada como sindrômicas e estar associada às alterações cromossômicas estruturais ou numéricas, ou como não sindrômica, quando relacionada, principalmente, com os polimorfismos de nucleotídeos simples (SNPs) em alelos que atuam como herança monogênica, ou ainda com a interação vários genes (poligênica multifatorial). Apesar de existirem muitas etiologias diferentes, normalmente a obesidade é tratada a partir da mesma abordagem, desconsiderando a fisiologia que a desencadeou. Dessa forma, o objetivo do presente trabalho foi abordar a obesidade genética não sindrômica por meio a) da descrição breve de perspectiva histórica sobre seu entendimento; b) da exposição dos principais mecanismos moleculares envolvidos com o controle de peso; c) da compilação dos principais genes e SNPs relacionados; d) da definição dos principais genes; e e) da abordagem das principais perspectivas de intervenção.


Obesity is defined as excess body fat accumulated in the adipose tissue when the individual reaches BMI values equal to or greater than 30 kg/m2. It is one of the main risk factors for several non-communicable diseases (NCDs), such as Type 2 Diabetes mellitus (T2D), cardiovascular diseases, high blood pressure, stroke and even cancer. Although obesity is directly related to excessive calorie intake in relation to daily energy expenditure, its etiology may be associated with low levels of physical activity, neuroendocrine changes, and genetic factors. Considering the genetic component, it can be classified as syndromic and be associated with chromosomal or numerical changes, or as non-syndromic and being related mainly to single nucleotide polymorphisms (SNPs) in alleles that act as monogenic inheritance, or with an interaction of several genes (multifactorial polygenic). Although there are many different etiologies, obesity is usually treated using the same approach, disregarding the physiology that triggered it. Thus, the aim of this study was to address non-syndromic genetic obesity through a) a brief description of a historical perspective on its understanding; b) the exposure of the main molecular mechanisms involved in weight control, c) the compilation of the key genes and related SNPs, d) the definition of the key genes and e) the approach of the main intervention representations.

ABSTRACT

Los estudiantes de medicina pueden estar expuestos a infecciones graves relacionadas con la atención de la salud si no siguen las medidas de prevención y control. Hay información limitada sobre el conocimiento y la percepción de los estudiantes de medicina con respecto a la bioseguridad y los enfoques educativos utilizados para enseñarles estas prácticas. El objetivo fue evaluar el conocimiento y la percepción de los estudiantes de medicina hacia las prácticas básicas de bioseguridad. Una encuesta descriptiva y transversal basada en entrevistas incluyó a 120 estudiantes de medicina de la Universidad Regional Autónoma de los Andes, Ecuador. Los estudiantes completaron un cuestionario sobre el conocimiento y la percepción con respecto a las prácticas de bioseguridad. El conocimiento de los estudiantes se evaluó por sus respuestas correctas a las preguntas del instrumento. El 57,5% de los estudiantes cumplen con las medidas de bioseguridad. La mayoría de los estudiantes perciben alto de riesgo de exposición a través de diferentes rutas con distintos patógenos, el argumento mayormente reportado fue el que puede ocurrir un accidente. Se observó que 81(67,5%) de los estudiantes mostraron tener conocimiento adecuado sobre bioseguridad, mientras que 39 demostraron lo contrario. El conocimiento sobre la bioseguridad fue bueno aunque se necesita más énfasis para mejorar su conocimiento en secciones como la técnica de colocación de guantes, momento de colocarse el gorro y qué es una sustancia antiséptica. Los cursos de Prevención y Control de Infecciones se pueden impartir a partir de su primer año de educación universitaria(AU)


Medical students can be exposed to serious health care-associated infections, if they are not following prevention and control measures. There is limited information on medical students' knowledge and perception of biosafety and the educational approaches used to teach these practices. The objective was to evaluate the knowledge and perception of medical students towards basic biosafety practices. A descriptive and cross-sectional, interview-based survey included 120 medical students from the Autonomous Regional University of the Andes, Ecuador. The students completed a questionnaire on knowledge and perception regarding biosafety practices. The knowledge of the students was evaluated by their correct answers to the questions of the instrument. 57.5% of students comply with biosafety measures. Most of the students perceive a high risk of exposure through different routes with different pathogens, the most reported argument was that an accident can occur. It was observed that 81 (67.5%) of the students showed adequate knowledge about biosafety, while 39 showed the opposite. Biosafety knowledge was good although more emphasis is needed to improve their knowledge in sections such as gloving technique, time to put on the cap and what is an antiseptic substance. Infection Prevention and Control courses can be taught beginning in your first year of college education(AU)

ABSTRACT

El SARS COV 2, tomó por sorpresa al mundo, con impacto en el sector salud, generándose una gran crisis sanitaria, golpeados por escasez de insumos, de equipos, de personal y capacidad instalada insuficiente para la atención de la contigencia. Ademas, la infodemia, el pánico y el miedo con sus respectivas consecuencias, se empodero de la sociedad civil, situación que no es ajena a sector salud, por ello, este relato de experiencia tuvo objetivo describir la gestión del servicio de medicina crítica de un hospital de Guayaquil- Ecuador durante la pandemia por el Coronavirus. En los centros asitenciales, el personal se enfrenta all desafío sanitario, principalmente en la gestión del servicio de medicina crítica. Al ser nombrado hospital centinela, con una capacidad instadala redujo de 494 a 200 camas, y se creó además el área de hospitalización de infectología; La interrelación de profesionales de la enfermería, médicos infectólogos, médicos neumólogos, servicios de terapia física y rehabilitación, servicios de nutrición, y los terapistas respiratorios, fue fundamental para afrontar la crisis, para vela por el bienestar del paciente, no solo en la parte física, sino psicología y de humanización. No obtante, el miedo a lo desconocido inherente a la especie humana, se transforma en pánico ante esta enfermedad provocando emociones, sentimientos, vivencias exacerbadas, y la inseguridad y desconfianza en que el sistema sanitario(AU)


SARS COV 2 took the world by surprise, with an impact on the health sector, generating a major health crisis, hit by a shortage of supplies, equipment, personnel and insufficient installed capacity for contingency care. In addition, the infodemic, panic and fear with their respective consequences, empowered civil society, a situation that is not unrelated to the health sector, therefore, this experience report aimed to describe the management of the critical medicine service of a Guayaquil-Ecuador hospital during the Coronavirus pandemic. In care centers, the staff faces the health challenge, mainly in the management of the critical medicine service. Being named a sentinel hospital, with an installed capacity it was reduced from 494 to 200 beds, and the infectious disease hospitalization area was also created; The interrelation of nursing professionals, infectious disease doctors, pulmonologists, physical therapy and rehabilitation services, nutrition services, and respiratory therapists, was essential to face the crisis, to ensure the well-being of the patient, not only in the physics, but psychology and humanization. However, the fear of the unknown inherent in the human species is transformed into panic in the face of this disease, causing emotions, feelings, exacerbated experiences, and insecurity and distrust in the health system(Au)

ABSTRACT

La gestión de los residuos sanitarios requiere atención especial y todos los equipos sanitarios deben participar en la manipulación de los residuos. Se presta menos atención a la gestión de residuos sanitarios en países en vías de desarrollo y no hay evidencia sobre las prácticas de gestión de residuos sanitarios en algunas instituciones sanitarias. Este estudio se realizó para evaluar las prácticas de gestión de residuos sanitarios y los factores asociados en tres hospitales de Perú. Es un estudio descriptivo, cuantitativo y de corte transversal basado en tres establecimientos de salud. Los datos se recopilaron mediante cuestionarios y listas de verificación de observación. El (66,67%) de los trabajadores conocían sobre el manejo de los desechos biológicos. La mayoría conocía los riesgos asociados con el manejo de los mismos (95,91%). Los participantes tenían el conocimiento de que pueden evitarse las infecciones. Nueve de cada diez de los trabajadores realizaron por lo menos dos capacitaciones en la gestión del manejo de los desechos biológicos. El 95,91% conocía los códigos de colores correctos de los contenedores para diferentes flujos de desechos. En cuanto a las actitudes, 161 (94,15 %) indicó que la gestión de los desechos biológicos era importante y 162 (94,74%) estuvo de acuerdo en que era necesaria una implementación estricta para la gestión adecuada de los mismos en el establecimiento de salud. Elementos clave para mejorar las prácticas de gestión de residuos sanitarios en hospitales: promover prácticas que reduzcan el volumen de residuos generados y aseguren una adecuada segregación de residuos(AU)


Healthcare waste management requires special attention and every healthcare teams should be involved in handling of wastes. However, less attention is paid to health care waste management in developing countries and there is no evidence on health care waste management practices in some institutions providing health services. This study was conducted to assess healthcare waste management practices and associated factors in three hospitals in Peru. It is a descriptive, quantitative and cross-sectional study based on three health establishments. Data were collected using questionnaire and observational checklists. The (66.67%) of the workers knew about the management of biological waste. The majority knew the risks associated with handling them (95.91%). Participants were aware that infections can be prevented. Nine out of ten of the workers completed at least two trainings in the management of biological waste. 95.91% knew the correct container color codes for different waste streams. Regarding attitudes, 161 (94.15%) indicated that the management of biological waste was important and 162 (94.74%) agreed that strict implementation was necessary for proper management of biological waste in the environment health facility. Key elements to improve healthcare waste management practices in hospitals: promote practices that reduce the volume of waste generated and ensure proper waste segregation(AU)
