Introduction: Epidermal growth factor precursor is immersed in the context to Platelets membrane. The regular procedure to obtain serum implies a barrier to biological understanding of the theoretical meaning of its values. Objective: To describe the effect to modified procedure to measure sample epidermal growth factors and the possible biological implications for this. Method: An in vitro experimental study was carried put, with blood samples from individuals with apparent health history, in adulthood. Serum epidermal growth factor precursor values were determined with the UMELISA-EGF kit recommended by the manufacturer; the experimental variation in sample collection was carried out according to SAMERSAC recommendations for platelet-rich plasma, with adjustments. Results: The average age was 45.89± 3.35 years, in a range of 27 to 62 years. The female sex predominates in a 1.8:1 ratio. Application of the experimental procedure showed significant and notable differences between the epidermal growth factor values (g=17.7; p=0.0001-23); no linear correlation was evident between the values (r= 0.1305; p= 0.6843). The "reserve" value was on average 1498.61 ±160.68 pg*mL-1, observing large effect differences, as well as a similar behavior to a transition value. The observed data suggest, a posteriori, consumption effect on the course of platelet lysis under standard conditions. Conclusions: Epidermal growth factor values are higher after platelet isolation; the existence of an intraplatelet reserve of epidermal growth factor is plausible. [ABSTRACT FROM AUTHOR]

Antecedentes: en bucerros al igual que en terneros el calostro brinda inmunidad durante las primeras semanas de vida, debido a las inmunoglobulinas presentes y que disminuyen el riesgo de infección y mortalidad. Objetivo: evaluar en campo la calidad del calostro bufalino y la transferencia de inmunidad pasiva en bucerros en un área del trópico bajo colombiano. Métodos: mediante un muestreo no probabilístico en cuatro empresas bufaleras en Córdoba (Colombia), se recolectaron muestras de calostro del primero al cuarto ordeño en 64 búfalas por dos métodos de evaluación y una muestra de sangre de sus crías para evaluar la transferencia de inmunidad pasiva mediante refractómetro. Resultados: por calostrómetro el 92,99 % de las muestras evaluadas fueron de buena a mediana calidad y por el refractómetro el 59,37 %; la correlación entre estos dos instrumentos fue alta. Hubo diferencia altamente significativa (p < 0,01) entre el número de ordeños a través del tiempo y la calidad del calostro, pero no hubo diferencia estadística entre la calidad por número de lactancias, por raza, por empresa y entre los dos instrumentos de evaluación. En el 92,19 % de los bucerros no hubo fallas en la transferencia de inmunidad pasiva. La transferencia de inmunidad pasiva no varió entre bucerros de diferente sexo y nacidos de búfalas de uno o más partos. Conclusiones: la calidad composicional del calostro bufalino no presentó diferencias por raza, número de lactancias, pero si a través del tiempo. [ABSTRACT FROM AUTHOR]

Hysteroscopy is an exploratory endoscopic technique that studies the interior of the uterine cavity and the endocervical canal. Various fluids, such as physiological saline, are used to optimise visualisation of the internal structures during this procedure. A rare complication of hysteroscopy is fluid overload, which can be associated with intravascular absorption syndrome, usually after lengthy procedures or tissue dissection. There are no data on the incidence and prevalence of this syndrome, and few cases involving physiological saline solution have been reported. We present a case of hysteroscopic myomectomy complicated by vascular absorption syndrome, which gave rise to acute pulmonary oedema that required admission to the intensive care unit., (Copyright © 2023.

Introduction and Objectives: Modular neck primary stems were introduced with the theoretical advantage of restoring the hip anatomy more precisely. However, the presence of a second junction has been associated with increased corrosion and release of metal debris. The objective of our study is to quantify of chromium and cobalt serum values, and to analyze their temporal evolution during five years., Material and Methods: We present a prospective series of 61 patients who underwent primary total hip arthroplasty by implantation of the HMAX-M® stem (Limacorporate, San Daniele, Italy). Serum chromium and cobalt determinations were performed at six months, two years and five years., Results: Our series shows a progressive elevation in chromium levels with a significant difference between chromium values at six months (0.35±0.18) and five years (0.52±0.36), P=.01. Regarding cobalt, a statistically significant elevation is observed between six months and two years and a subsequent stabilization of values between two and five years, with a cobalt mean at six months (1.17±0.8) significantly lower than at two (2.63±1.76) and five years (2.84±2.1), P=.001., Conclusion: Elevated serum cobalt levels have been observed in patients who underwent modular neck stem implantation. The results obtained in this study have limited the use of stems with a modular neck in our clinical practice., (Copyright © 2023 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.)
