ObjectiveTo evaluate the measles surveillance system （MSS） in Jiading District， Shanghai from 2020 to 2022， and to provide evidence for the elimination of measles. MethodsDescriptive methods were used to analyze the MSS data and confirmed measles cases from 2020 to 2022 and to evaluate MSS performance indicators. ResultsA total of 120 suspected cases were reported through the MSS from 2020 to 2022， of which 12 were classified as measles， 9 as rubella， and 99 as non-measles /rubella. The incidence of reported non-measles /rubella was 1.44 per 100 000 population in 2020， 2.01 per 100 000 population in 2021， and 1.99 per 100 000 population in 2022. The rates of complete investigation within 48 hours， blood samples and etiology collection， timely delivery， and timely reporting were all 100%. Among the 12 confirmed measles cases from 2020 to 2022， seven routine immunization subjects completed the required doses of measles vaccines， while two out five adult cases had a history of measles vaccine-related immunization. The confirmed cases comprised six with fever accompanied by rash， five with rash alone， and one with fever alone. ConclusionThe MSS results in Jiading District， Shanghai are overall satisfactory. However， there is a need to improve sensitivity， especially in detecting and reporting cases with atypical symptoms. It is imperative to maintain high vaccination coverage for age-appropriate children， promote supplementary immunization activities， and elevate the overall immunity of the entire population.

Differential Analysis of Erythrocyte Flexibility of PbK173 Artemisinin-sensitive Strains / 中国实验方剂学杂志

ObjectiveTo detect the flexibility differences of Plasmodium berghei K173 （PbK173）-infected red blood cells with varying degrees of sensitivity to artemisinin-based drugs and to preliminarily explore the underlying mechanisms of the differences. MethodA total of 102 specific-pathogen-free （SPF） male C57BL/6 mice were randomly divided into three groups， with 30 mice each in the control group and PbK173-resistant （PbK173-R） group， and 42 mice in the PbK173-sensitive （PbK173-S） group. Except for the control group， the rest groups were vaccinated with 1×107 PbK173-S/PbK173-R infected red blood cells to establish a mouse malaria model. During the administration and recovery periods （control group， PbK173-R/PbK173-S）， dihydroartemisinin （DHA， 40 mg·kg-1） and malaridine （MD， 6 mg·kg-1） were administered continuously for four days. Peripheral blood was taken from the PbK173-S/PbK173-R groups with an infection rate equal to or greater than 20%. Peripheral blood and each organ were taken on the first day at the end of administration （dosing period） and on the fifth day at the end of administration （recovery period）， and blood parameters and organ indices of each group were examined. The osmotic fragility of peripheral blood red blood cells in each group was detected using the red blood cell osmotic fragility test. Western blot was applied to determine the levels of Piezo1 and Band3 proteins in the red blood cell membrane. ResultDuring the administration and recovery periods， there were no significant differences between the PbK173-S MD group and the DHA group. During the administration period， there were no significant differences in hematological parameters between PbK173-S and PbK173-R in the MD group. However， during the recovery period， the red blood cell count， hemoglobin concentration and hematocrit of the PbK173-R group were significantly higher than those of the PbK173-S group （P<0.05） in the MD group. Compared with that of the control group， the osmotic fragility of the PbK173-S/PbK173-R groups was significantly enhanced （P<0.01）， and the osmotic fragility of the PbK173-S group was significantly stronger than that of the PbK173-R group （P<0.01）. The osmotic fragility of red blood cells in the PbK173-S group during the administration period was significantly stronger than that in the control group and PbK173-R group during the administration period （P<0.01）. The osmotic fragility of red blood cells in the PbK173-R group during the recovery period was significantly higher than that in the control group during the administration period and the PbK173-S group during the recovery period （P<0.05）. Compared with those in the control group， the Piezo1 protein and Band3 protein in the red blood cell membrane of the PbK173-S group were significantly reduced （P<0.01）. Compared with those in the PbK173-R group， the Piezo1 protein and Band 3 protein in the red blood cell membrane of the PbK173-S group were significantly reduced. ConclusionThe flexibility of PbK173-infected red blood cells with different sensitivities to artemisinins differed. Plasmodium-infected red blood cells significantly reduced the levels of Piezo1 and Band3 proteins in the red blood cell membrane， and the erythrocyte flexibility exhibited a decreasing trend in the following order： normal group， PbK173-R group， and PbK173-S group.

Unlocking the potential of amorphous calcium carbonate: A star ascending in the realm of biomedical application

Calcium-based biomaterials have been intensively studied in the field of drug delivery owing to their excellent biocompatibility and biodegradability. Calcium-based materials can also deliver contrast agents, which can enhance real-time imaging and exert a Ca2+-interfering therapeutic effect. Based on these characteristics, amorphous calcium carbonate (ACC), as a brunch of calcium-based biomaterials, has the potential to become a widely used biomaterial. Highly functional ACC can be either discovered in natural organisms or obtained by chemical synthesis However, the standalone presence of ACC is unstable in vivo. Additives are required to be used as stabilizers or core-shell structures formed by permeable layers or lipids with modified molecules constructed to maintain the stability of ACC until the ACC carrier reaches its destination. ACC has high chemical instability and can produce biocompatible products when exposed to an acidic condition in vivo, such as Ca2+ with an immune-regulating ability and CO2 with an imaging-enhancing ability. Owing to these characteristics, ACC has been studied for self-sacrificing templates of carrier construction, targeted delivery of oncology drugs, immunomodulation, tumor imaging, tissue engineering, and calcium supplementation. Emphasis in this paper has been placed on the origin, structural features, and multiple applications of ACC. Meanwhile, ACC faces many challenges in clinical translation, and long-term basic research is required to overcome these challenges. We hope that this study will contribute to future innovative research on ACC.

AIM: To study the perception of first-order grating acuity and second-order spatial contrast sensitivity in patients with monocular anisometropia amblyopia.METHODS:A total of 715 children(715 eyes)diagnosed as monocular anisometropia amblyopia in our hospital from January 2018 to December 2022 were collected as amblyopia group, and 745 children(745 eyes)with normal corrected visual acuity were collected. The best corrected visual acuity(BCVA), first-order grating acuity and/or second-order spatial contrast sensitivity were measured, repectively. The perception ability of amblyopia patients to first-order grating acuity and second-order spatial contrast sensitivity were analyzed.RESULTS:There were significant differences between amblyopia group and normal control group in the perception of first-order grating acuity(11.58±6.10 vs. 20.27±3.47, P&#x0026;#x003C;0.001)and second-order spatial contrast sensitivity(0.33±0.16 vs 0.12±0.04, P&#x0026;#x003C;0.001). And there were significant differences between mild-to-moderate amblyopia and severe amblyopia patients in first-order grating acuity(12.10±6.23 vs. 8.13±3.70, P&#x0026;#x003C;0.001)and second-order spatial contrast sensitivity(0.32±0.16 vs. 0.37±0.17, P&#x0026;#x003C;0.05).CONCLUSION: The first-order and second-order visual pathway of the cerebral cortex in children with monocular anisometropia amblyopia have different degrees of damage. The injury of severe amblyopia is more serious than that of mild-to-moderate amblyopia.

Prevalence and antimicrobial resistance profile of pathogens isolated from patients with urine tract infections admitted to a university hospital in a medium-sized Brazilian city

ABSTRACT This study aimed to determine the antibiotic profile of microorganisms isolated from urine samples of patients with community urine tract infections (UTI) admitted to the University Hospital of the Federal University of Sao Carlos to support an appropriate local empirical treatment. A retrospective cross-sectional study was conducted from October 2018 to October 2020. Data from 1,528 positive urine cultures for bacterial pathogens and antibiograms were tabulated. Bacterial species prevalence and their resistance profile were analyzed and compared by sex and age. For Gram-negative fermenting bacteria, resistance rates were compared between patients with previous hospitalization and the total of infections caused by this group. For comparisons, the Chi-square test was performed, using Fisher's exact test when necessary (BioEstat program, adopting p ≤ 0.05). A multivariate analysis was applied to assess the effect of the studied variables in predicting multidrug resistance. Infections were more prevalent in women and older adults. Gram-negative bacteria represented 90.44% of total cultures. In both sexes, E. coli prevalence was significantly higher in adults compared with older adults (p < 0.0001). For several antibiotics, resistance rates were higher in the older adults compared with other ages and in patients with Gram-negative fermenting infections and previous hospitalization compared with the total of infections by this group of bacteria. The closer to the hospitalization, the higher the number of antibiotics with superior resistance rates. Resistance rates for aminoglycosides, carbapenems, ceftazidime, nitrofurantoin, piperacillin+tazobactam, and fosfomycin were less than 20%, considered adequate for empirical treatment. Only hospitalization in the previous 90 days was statistically significant in predicting infections by multidrug-resistant bacteria.

ABSTRACT Background: Accelerated diagnostic protocols for chest pain, with the advancement of high-sensitivity troponin, make it possible to identify patients admitted to the emergency department with chest pain and low risk for a major adverse cardiovascular event, who could be discharged immediately, early and safely, saving time and resources. Objective: The aim of this study was to assess clinical trials using accelerated diagnostic protocols based on high-sensitivity troponin. Methods: A search of randomized clinical trials evaluating accelerated diagnostic protocols based on high-sensitivity troponin in emergency services was carried out in MEDLINE/Ovid, Cochrane and EMBASE database, using the assessment criteria of the Cochrane manual and the PRISMA strategy. Results: After screening 3509 studies, 5 clinical trials, including 1513 patients, were analyzed. Early discharges were identified in 409 (27%) of patients, in 91% of cases for ESC 0/3-h protocols, 72% for 0/1-h, 48% for EDACS, 40% for HEART, 19% and 32% for ADAPT and 8% and 18% for standard care protocols. The negative predictive value was high, in the 99.1-100% range. Mean length of hospital stay was lower for the 0/1-h and ESC 0/3-h protocols, with 4.6 and 5.6 hours, respectively. Conclusions: Accelerated diagnostic protocols in chest pain using high-sensitivity troponin allow a higher proportion of early discharges with a low rate of major cardiovascular events, with reduction in length of hospital stay and resources used.

The relationship between covid-19 burnout and the moral sensitivity of healthcare professionals

This study aimed to examine the relationship between the burnout of physicians and nurses and their moral sensitivity during the pandemic. This was a descriptive and correlational study. This study was carried out with physicians and nurses who were continuing to work actively during the pandemic. Snowboard sampling method was utilized. The total mean score of the participants on the MSQ was 90.78±19.10. The total mean score of the COVID-19 Burnout Scale was 34.52±9.65. A statistically weak and significant correlation was found between the COVID-19 Burnout Scale and the MSQ total score, as well as the "benefit" and "conflict" sub-dimensions. It was determined that as MSQ total scores, "benefit" and "conflict" scores decreased in healthcare workers, COVID-19 burnout scores increased. In our study, the moral sensitivity of the participants was found to be moderate, and their burnout levels were found to be high. Although there was a weak relationship, it was observed that burnout levels increased as moral sensitivity levels increased. It is crucial that we learn from pandemic experiences and transfer this knowledge to future generations. In particular, we must assimilate these important lessons into training in order to develop and protect the moral sensitivity of healthcare professionals.

Este estudio pretendía examinar la relación entre el burnout de médicos y enfermeras y su sensibilidad moral durante la pandemia. Se trató de un estudio descriptivo y correlacional, y se llevó a cabo con médicos y enfermeras que seguían trabajando activamente durante la pandemia. Se utilizó el método de muestreo de Snowboard. La puntuación media total de los participantes en el MSQ fue de 90,78±19,10. La puntuación media total de la Escala de Burnout COVID-19 fue de 34,52±9,65. Se encontró una correlación estadísticamente débil y significativa entre la Escala de Burnout COVID-19 y la puntuación total del MSQ, así como las subdimensiones "beneficio" y "conflicto". Se determinó que, a medida que disminuían las puntuaciones totales del MSQ y las puntuaciones de "beneficio" y "conflicto" en los trabajadores sanitarios, aumentaban las puntuaciones de burnout de la COVID-19. En nuestro estudio, se observó que la sensibilidad moral de los participantes era moderada y que sus niveles de burnout eran elevados. Aunque existía una relación débil, se observó que los niveles de burnout aumentaban a medida que lo hacían los de sensibilidad moral. Es crucial que aprendamos de las experiencias pandémicas y transmitamos estos conocimientos a las generaciones futuras. En particular, debemos asimilar estas importantes lecciones en la formación para desarrollar y proteger la sensibilidad moral de los profesionales sanitarios.

Esse estudo objetivou examinar a relação entre o burnout de médicos e enfermeiras e sua sensibilidade moral durante a pandemia. Esse era um estudo descritivo e correlacional. Esse estudo foi realizado com médicos e enfermeiras que continuaram trabalhando ativamente durante a pandemia. O método da amostragem em snowboard foi utilizado. A média total dos participantes no MSQ foi 90,78±19,10. A média total na Escala de Burnout pela COVID-19 foi 34,52±9,65. Uma correlação fraca e significante foi encontrada entre os escores totais na Escalas de Burnout pela COVID-19 e MSQ, assim como nas subdimensões "benefício" e "conflito". Determinou-se que como os escores totais na MSQ e os escores "benefício" e "conflito" diminuiram em trabalhadores de cuidados à saúde, os escores de burnout pela COVID-19 aumentaram. Em nosso estudo, a sensibilidade moral dos participantes foi considerada ser moderada e seus níveis de burnout considerados serem altos. Embora tenha havido uma correlação fraca, foi observado que os níveis de burnout aumentaram quando os níveis de sensibilidade moral aumentaram. É essencial que aprendamos das experiências com a pandemia e passemos esse conhecimento para as futuras gerações. Em particular, nós devemos assimilar essas importantes lições em treinamentos, de forma a desenvolver e proteger a sensibilidade moral de profissionais de cuidados à saúde.

Colonización genitourinaria por Streptococcus agalactiae y perfil de sensibilidad en mujeres gestantes

Introducción: Streptococcus agalactiae, también conocido como estreptococo beta-hemolítico del grupo B de Lancefield, adquiere relevancia durante el embarazo debido a la posibilidad de transmisión al recién nacido. Las normas internacionales sugieren realizar tamizaje vagino-anal entre las 35 y 37 semanas de gestación. Objetivo: Determinar prevalencia de colonización por Streptococcus agalactiae en muestras cérvico-vaginales de embarazadas entre 35 y 37 semanas, y en urocultivos de gestantes de cualquier edad gestacional ingresadas en el hospital ginecobstetrico provincial, así como su perfil de sensibilidad. Materiales y métodos: Se realizó un estudio observacional, descriptivo y exploratorio, de corte transversal, entre enero y agosto de 2021, en el Hospital Provincial Docente Ginecobstétrico José Ramón López Tabrane, de la ciudad de Matanzas. El universo estuvo conformado por todas las gestantes de cualquier trimestre a las que se les realizó urocultivo, y estudio microbiológico cérvico-vaginal entre las 35 y 37 semanas de gestación, cumplidos previamente criterios de inclusión. Resultados: El 18,61 % presentó cultivos positivos para Streptococcus agalactiae. Predominó la presencia de positividad en gestantes no diabéticas; se encontró un 18,75 % de urocultivos positivos. Predominaron los aislamientos sensibles a eritromicina y clindamicina, con un 63 %, seguidos de la resistencia inducible a clindamicina (MLSBi), con un 19 %. Conclusiones: El diagnóstico microbiológico de Streptococcus agalactiae en gestantes, es de vital importancia para la prevención de sepsis puerperal y neonatal. A pesar de que los resultados de este estudio muestran perfiles de sensibilidad adecuados, su monitorización permanente garantizaría el diagnóstico precoz de cepas resistentes, dado el ligero incremento del fenotipo (MLSBi) identificado.

Introduction: Streptococcus agalactiae, also known as Lancefield's group B beta-hemolytic streptococcus, acquires relevance during pregnancy due to the possibility of transmission to the newborn. International standards suggest performing vaginal-anal screening between 35 and 37 weeks of gestation. Objective: to determine the prevalence of colonization by Streptococcus agalactiae, in cervical-vaginal samples of pregnant women between 35 and 37 weeks, and in urine cultures of pregnant women of any gestational age admitted to the provincial gyneco-obstetric hospital, as well as their sensitivity profile. Materials and methods: an observational, descriptive and exploratory cross-sectional study was performed, between January and August 2021, at the Provincial Teaching Gyneco-obstetric Hospital Jose Ramon Lopez Tabrane of Matanzas. The universe was made up by all pregnant women of any trimester who underwent a urine culture, and a cervical-vaginal microbiologic study between 35 and 37 gestation weeks, previously meeting inclusion criteria. Results: 18.61% presented positive cultures for Streptococcus agalactiae. The presence of positivity predominated in non-diabetic women. 18.75 % of positive urine cultures were found. Erythromycin and clindamycin-sensitive isolates predominated (MLSBi), with 63%, followed by inducible resistance to clindamycin, with 19%. Conclusions: the microbiological diagnosis of Streptococcus agalactiae in pregnant women is of vital importance to prevent puerperal and neonatal sepsis. Although the results of this study show adequate sensitivity profiles, its permanent monitoring would warrantee the early diagnosis of resistant strains, given the slight increase of the phenotype (MLSBi) identified.

In vitro sensitivity of Malassezia furfur isolates from HIV-positive and negative patients to antifungal agents / Sensibilidad in vitro a antifúngicos de aislamientos de Malassezia furfur de pacientes positivos y negativos para HIV

Introduction. Malassezia is a lipophilic and lipid-dependent yeast genus belonging to the skin microbiota of humans and other animals. However, due to dysbiosis processes or other factors in the host, this yeast can cause different pathologies, ranging from skin diseases, such as seborrheic dermatitis, to fungemia. Isolation of Malassezia furfur has been reported in HIV-positive patients with or without skin lesions. Due to its opportunistic nature and its variable resistance to antifungal compounds, it is relevant to know the Malassezia sensitivity profiles. Objective. To determine the sensitivity to different antifungal agents, of clinical isolates of M. furfur obtained from HIV-positive or negative patients, with or without seborrheic dermatitis. Materials and methods. Assessment of isolates sensitivity to itraconazole, voriconazole, fluconazole, and amphotericin B was performed by two techniques: (1) Broth microdilution using Clinical and Laboratory Standards Institute (CLSI) protocol M27-A3 with modifications; and (2) agar tests using Etest®. Results. Isolates obtained from HIV patients showed an increase in the minimum inhibitory concentration of fluconazole, voriconazole, and amphotericin B, compared with those of non-HIV patients. Itraconazole was the antifungal with the lowest minimum inhibitory concentration (MIC) in most isolates. Conclusion. We observed differences in the sensitivity profiles of M. furfur isolates according to the context of the patient. High MIC of antifungals like fluconazole, commonly used for treating pathologies caused by Malassezia, were identified.

Introducción. Malassezia es un género de levaduras lipofílicas que dependen de los lípidos y hacen parte de la microbiota de la piel de humanos y otros animales. No obstante, debido a procesos de disbiosis u otros factores en el huésped, esta levadura puede llegar a causar diferentes enfermedades: desde cutáneas (como dermatitis seborreica) hasta fungemias. Se han reportado aislamientos de Malassezia furfur en pacientes positivos para HIV, con lesiones cutáneas o sin ellas. Por su carácter oportunista y sensibilidad variable a los compuestos antifúngicos, es relevante conocer los perfiles de sensibilidad. Objetivo. Determinar la sensibilidad a diferentes antifúngicos de aislamientos clínicos de M. furfur obtenidos de pacientes positivos o negativos para HIV, con dermatitis seborreica o sin ella. Materiales y métodos. La sensibilidad de los aislamientos a itraconazol, voriconazol, fluconazol y anfotericina B, se determinó mediante dos técnicas: microdilución en caldo según el protocolo M27-A3 del Clinical & Laboratory Standards Institute (CLSI), con modificaciones, y pruebas en agar mediante Etest®. Resultados. Los aislamientos obtenidos de pacientes con HIV mostraron aumento de la concentración inhibitoria mínima a fluconazol, voriconazol y anfotericina B, en comparación con los de pacientes sin HIV. Por otro lado, al evaluar la mayoría de los aislamientos, el itraconazol fue el antifúngico con la menor concentración inhibitoria mínima. Conclusión. Se evidencian diferencias en los perfiles de sensibilidad de los aislamientos de M. furfur, según el contexto del paciente, y elevadas concentraciones inhibitorias mínimas de antifúngicos como el fluconazol, usados comúnmente para el tratamiento de las enfermedades causadas por Malassezia spp.

Fetal echocardiography should be included as a part of routine antenatal screening irrespective of risk factors for congenital cardiac structural anomalies.

Efectividad del tratamiento con atropina versus oclusiones en pacientes con ambliopía refractiva moderada unilateral

Objetivo: Comparar la efectividad del tratamiento de atropina versus oclusión ocular en pacientes con ambliopía refractiva moderada unilateral. Métodos: Se realizó un estudio descriptivo, longitudinal y prospectivo de una serie de casos que acudieron a la consulta de Oftalmología Pediátrica del Instituto Cubano de Oftalmología Ramón Pando Ferrer durante el período comprendido de septiembre del 2019 a septiembre de 2021. La muestra quedó conformada por 44 pacientes, los cuales se dividieron de forma aleatoria en dos grupos de estudio, 22 casos al grupo de oclusiones e igual número al grupo de atropina, que cumplían los criterios de inclusión. Se analizaron las variables edad, sexo, defecto refractivo, agudeza visual mejor corregida, sensibilidad al contraste y estereopsis. Resultados: Predominó el astigmatismo hipermetrópico en ambos grupos de estudio. La media de la agudeza visual mejor corregida inicial en ambos grupos fue de 0,4 LogMAR y mejoró a 0,1 LogMAR al finalizar el tratamiento. La media de la sensibilidad al contraste inicial fue de 1,48 (±19,75) para el grupo de oclusiones y de 1,47 (±20,5) para el grupo atropina, al finalizar alcanzaron 1,59 (±10,1) y 1,57 (±10,0) por orden de mención. La estereopsis inicial fue subnormal en ambos grupos, al finalizar el tratamiento fue normal en el 77,3 % grupo oclusión y el 68,2 % grupo atropina. Conclusiones: La efectividad del tratamiento en pacientes con ambliopía refractiva moderada unilateral con atropina es similar a la que se alcanza con la aplicación de la oclusión ocular.

Objective: To compare the effectiveness of atropine treatment versus ocular occlusion in patients with unilateral moderate refractive amblyopia. Methods: A descriptive, longitudinal and prospective study of a series of cases that attended the Pediatric Ophthalmology office of the Ramón Pando Ferrer Cuban Institute of Ophthalmology during the period from September 2019 to September 2021 was carried out. The sample consisted of 44 patients, who were randomly divided into two study groups, 22 cases to the occlusion group and the same number to the atropine group, who met the inclusion criteria. The variables age, gender, refractive defect, best corrected visual acuity, contrast sensitivity and stereopsis were analyzed. Results: Hypermetropic astigmatism predominated in both study groups. Average initial best-corrected visual acuity in both groups was 0.4 LogMAR and improved to 0.1 LogMAR at the end of treatment. Average initial contrast sensitivity was 1.48 (±19.75) for the occlusion group and 1.47 (±20.5) for the atropine group, at completion reaching 1.59 (±10.1) and 1.57 (±10.0) in order of mention. Initial stereopsis was subnormal in both groups, at the end of treatment it was normal in 77.3 % occlusion group and 68.2 % atropine group. Conclusions: The effectiveness of treatment in patients with unilateral moderate refractive amblyopia with atropine is similar to that achieved with the application of ocular occlusion.

Introducción: Existen varios sistemas de puntuación para predecir los resultados adversos en los pacientes con hemorragia digestiva alta no varicosa, pero no se han validado lo suficiente y cada uno pertenece a distintas poblaciones fuentes. Objetivo: Demostrar la utilidad de una escala propuesta para predecir las probabilidades de resangrado, de mortalidad y de necesidad de cirugía en los pacientes con hemorragia digestiva alta no varicosa. Métodos: Se realizó un estudio retrospectivo de una prueba diagnóstica en el hospital de Prenda, Luanda, Angola desde enero del 2021 hasta mayo del 2022. El universo estuvo formado por 93 pacientes atendidos durante ese período con el criterio de inclusión de tener el diagnóstico de hemorragia digestiva alta de origen no varicoso. Resultados: De un total de 93 pacientes se obtuvo como desenlace primario una recurrencia del sangrado de 18 pacientes para un 19,35 por ciento del total, seguido con 12 fallecidos para un 12,90 por ciento del total y cuatro fallecidos para un 4,40 por ciento del total. Los valores predictivos de la escala de forma general fueron, al ser aplicada una sensibilidad de 0,91, la especificidad de un 0,92, el valor predictivo negativo de un 0,95 y el valor predictivo negativo de un 0,86. Conclusiones: La escala propuesta tiene una sensibilidad y especificidad adecuada para predecir, en los pacientes con hemorragia digestiva alta no varicosa, la probabilidad de resangrado, de mortalidad y la necesidad de cirugía(AU)

Introduction: Several scoring systems exist to predict adverse outcomes in patients with nonvariceal upper gastrointestinal bleeding, but they have not been sufficiently validated and each pertains to different source populations. Objective: To demonstrate the usefulness of a proposed scoring scale to predict the probability of rebleeding, mortality, and need for surgery in patients with nonvariceal upper gastrointestinal bleeding. Methods: A retrospective study of a diagnostic test was performed at the hospital of Prenda, Luanda, Angola, from January 2021 to May 2022. The study universe consisted of 93 patients attended during that period, with the inclusion criterion of having a diagnosis of upper gastrointestinal bleeding of nonvariceal origin. Results: From a total of 93 patients, the primary outcome was a recurrence of bleeding in 18 patients, accounting for 19.35 percent of the total; followed by 12 deaths, representing 12.90 percent of the total, and four deaths, accounting for 4.40 percent of the total. After the scale was applied, the following general predictive values were obtained: sensitivity of 0.91, specificity of 0.92, negative predictive value of 0.95 and negative predictive value of 0.86. Conclusions: The proposed scale presents adequate sensitivity and specificity for predicting the probability of fatal rebleeding and the need for surgery in patients with nonvariceal upper gastrointestinal bleeding(AU)

Comparación ecotoxicológica al Cloruro de Sodio en Hydra vulgaris e Hydra viridissima

El aumento de la salinidad en los ecosistemas de agua dulce genera preocupación sobre los efectos adversos que puede provocar sobre las especies dulceacuícolas y el suelo. Las concentraciones óptimas de iones de sodio y calcio para que las especies del género Hydra tengan condiciones fisiológicas adecuadas son relativamente bajas. Este trabajo se enfocó en comparar la sensibilidad de H. vulgaris e H. viridissima frente al cloruro de sodio (NaCl). Las especies fueron mantenidas bajo condiciones de fotoperiodo, iluminación y temperatura controladas. Se obtuvieron las tasas de crecimiento y en ensayos de toxicidad aguda se calcularon las CE50 (Concentración efectiva media) y CL50 (Concentración letal media) como indicadores de la sensibilidad al NaCl. H. vulgaris fue más sensible al NaCl dado que la CL50-96h fue de 1,0 g/l NaCl (entre 0,8 - 1,2 g/l como intervalo de confianza al 95%), mientras que H. viridissima presentó una CL50-96h promedio de 2,6 g/l (entre 2,0 - 3,3 g/l como intervalo de confianza del 95%). Se considera que esta última fue más tolerante al NaCl, probablemente por la relación simbiótica con la microalga Chlorella vulgaris, ya que podría generar un efecto protector. Se espera que comprender el comportamiento de estos biomodelos respecto al aumento de la salinización permita la evaluación temprana de riesgos ecológicos en ecosistemas acuáticos tropicales.

The increase in salinity in freshwater ecosystems raises concern about the adverse effects that it can cause in freshwater species and the soil. The sodium and calcium ions optimum concentrations required for genus Hydra to have adequate physiological conditions are relatively low. This research compared the H. vulgaris and H. viridissima sodium chloride (NaCl) sensitivity. The species were propagated under photoperiod, lighting and temperature-controlled conditions. The growth rates were obtained and EC50 (mean effective concentration) and LC50 (mean lethal concentration) were calculated by means of acute toxicity tests as indicators of sensitivity to NaCl. For H. vulgaris the LC50-96h was 1.0 g/l of NaCl with a range between 0.8 - 1.2 g/l of NaCl, compared to H. viridissima presented an average LC50-96h of 2.6 g/l of NaCl with a 95% confidence interval between 2.0 - 3.3 g/l of NaCl. The H. viridissima was more tolerant, probably the symbiotic relationship with Chlorella vulgaris, can generate a protective effect. Understanding the behavior of these species with respect to increased salinization can allow an early assessment of ecological risks in tropical aquatic ecosystems.
