Association between early manifestations of infection or sepsis and prognosis in a high complexity hospital in the city of Medellín.

OBJECTIVE: To identify the first symptoms and signs of patients with suspected infection or sepsis and their association with the composite outcome of admission to the Intensive Care Unit (ICU) or mortality. DESIGN: Prospective cohort study between June 2019 and March 2020. SETTING: Hospital Universitario San Vicente Fundación, Colombia. PATIENTS: Over 18 years of age with suspicion or confirmation of sepsis, which required hospitalization. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Symptoms and signs associated with infection, with their time of evolution, specified in the study. RESULTS: From 1005 eligible patients, 261 were included. After multivariable adjustment with a logistic regression model, the main factors for ICU admission or mortality were heart rate (OR 1.04 with 95% CI 1.04-3.7), respiratory rate (OR 1.19 with 95% CI 1.0-1.4) and capillary refill time (OR 3.4 with 95% CI 1.9-6.1). CONCLUSIONS: Heart rate, respiratory rate, and capillary refill may behave as early predictors of ICU admission and mortality in cases of sepsis.

Evolución de la técnica follicular unit extraction (FUE) / Evolution of the follicular unit extraction (FUE) technique

El microtrasplante capilar, método FUE, es la cirugía para la recuperación capilar que consta en la extracción de unidades foliculares con punches de distintos diámetros y longitudes, desde una zona llamada dadora, generalmente occipital y/o temporal aunque pueden utilizarse otras partes del cuerpo como barba, tórax, abdomen y pubis, para luego de seleccionarse y conservarse en forma adecuada ser implantadas en la llamada zona receptora. Tanto los avances en la técnica como en el uso de instrumental de última generación generan resultados mejores y más naturales, con una recuperación más rápida y menor daño de sus zonas dadoras.

Hair transplant, FUE method, is surgery for hair recovery that consists of the extraction of follicular units with punches of different diameters and lengths, from an area called the donor; usually occipital and/or temporal; although they can be used on other parts of the body such as beard, thorax, abdomen and pubes. After being appropriately selected and preserved, they are implanted in the so-called receiving area. Both advances in technique and in the use of cutting-edge instruments generate better and more natural results, with faster recovery and less damage to the donor areas

Towards the personalization of septic shock resuscitation: the fundamentals of ANDROMEDA-SHOCK-2 trial.

Septic shock is a highly lethal and prevalent disease. Progressive circulatory dysfunction leads to tissue hypoperfusion and hypoxia, eventually evolving to multiorgan dysfunction and death. Prompt resuscitation may revert these pathogenic mechanisms, restoring oxygen delivery and organ function. High heterogeneity exists among the determinants of circulatory dysfunction in septic shock, and current algorithms provide a stepwise and standardized approach to conduct resuscitation. This review provides the pathophysiological and clinical rationale behind ANDROMEDA-SHOCK-2, an ongoing multicenter randomized controlled trial that aims to compare a personalized resuscitation strategy based on clinical phenotyping and peripheral perfusion assessment, versus standard of care, in early septic shock resuscitation.

Determination of bioavailable fluoride in toothpastes marketed in Medellín, Colombia, through capillary electrophoresis / Fluoruro biodisponible en cremas dentales comercializadas en Medellín ­ Colombia mediante electroforesis capilar

Currently, the FDI recommendation (World Dental Federation) for fluoride concen­tration in toothpastes is that the total fluoride content declared by manufacturers be between 1,000 and 1,500 ppm, and of this amount, at least 800 ppm should be bioavai­lable fluoride. The aim of this study was to describe the market of toothpastes marketed in Medellín and to measure the concentration of bioavailable fluoride by capillary elec­trophoresis to verify their compliance with the FDI recommendation for the prevention of dental caries. After sampling the toothpastes available for sale in the 16 communes of the city of Medellin, a single operator measured in triplicate the concentration of bioavailable fluoride in 36 samples of previously blinded toothpastes using the capi­llary electrophoresis (EC) technique. Most of the evaluated toothpastes that declared a content of 1,000­1,500 ppm fluoride met the recommendation of presenting at least 800 ppm bioavailable fluoride. Measurement of bioavailable fluoride in toothpastes with MFP (sodium monofluorophosphate) is recommended, as it is known that binding to the abrasive can decrease its concentration over time.

Actualmente la recomendación de la FDI (Federación Dental Internacional) sobre la concentración de fluoruro en cremas dentales es que el contenido de fluoruro total de­clarado por los fabricantes sea entre 1.000 y 1.500 ppm, y que de esta cantidad al menos 800 ppm sea fluoruro biodisponible. El objetivo de este estudio fue describir el mercado de las cremas dentales comercializadas en Medellín y medir en estas la concentración de fluoruro biodisponible por electroforesis capilar para verificar su cumplimiento de la recomendación de la FDI para la prevención de la caries dental. Luego de realizar un mues­treo en las 16 comunas de la ciudad de Medellín sobre las cremas dentales disponibles a la venta, un solo operador midió por triplicado la concentración de fluoruro biodisponible en 36 muestras de cremas dentales previamente cegadas, mediante la técnica de electroforesis capilar (EC). La mayoría de las cremas dentales evaluadas que declaraban contenido de 1.000 a 1.500 ppm de fluoruro, cumplieron la recomendación de presentar al menos 800 ppm de fluoruro biodisponible. Se recomienda realizar la medición del fluoruro biodisponible en las cremas con MFP, ya que se conoce que la unión al abrasivo puede disminuir su concentración en el tiempo.

Efluvio en línea de aparición inmediata asociado a trasplante capilar de alta densidad: descripción de 28 casos / Immediate-Onset Linear Effluvium Associated With High-Density Hair Transplantation: A Series of 28 Cases

Describimos 28 pacientes que desarrollaron una forma de efluvio postrasplante capilar con características no descritas en la literatura: a) morfología lineal; b) aparición inmediata (1-3 días); c) asociación con ‘dense packing’ en entradas (‘signo de Mickey Mouse’); d) progresión del diámetro de la línea (patrón ‘wave-like’); e) posible adición posterior de efluvio lineal concéntrico a vértex (‘signo del Donut’), y f) además de otros efluvios tampoco publicados por su inmediatez de aparición. La morfología lineal podría ser el resultado de la alta densidad colocada en nuestros pacientes, provocando hipoxia perilesional y efluvio de las unidades foliculares miniaturizadas que rodean la zona receptora. Debido a que la línea alopécica provoca inseguridad a los pacientes sobre una posible no colocación de injertos, recomendamos iconografía postoperatoria inmediata demostrando unión de áreas trasplantada y no trasplantada, así como la explicación previa al paciente de este fenómeno transitorio y completamente reversible en 3 meses (AU)

We describe 28 patients who experienced effluvium with previously unreported features shortly after hair transplant surgery. Notable features were as follows: a) a linear morphology; b) immediate onset (1-3 days); c) association with dense-pack grafting in areas of receding hairline at the temples (Mickey Mouse pattern); d) a progressive increase in the diameter of the hair loss line (wave-like pattern); e) in some cases, subsequent concentric linear effluvium on the crown (donut pattern); and f) other forms of previously unreported immediate-onset effluvium. The linear morphology could be the result of dense packing, which can cause perilesional hypoxia and loss of miniaturized hairs around the recipient area. Since linear hair loss can cause patient concern about graft failure, we recommend taking images of transplanted and nontransplanted areas immediately after surgery and warning patients in advance about these transient effects, which are fully reversed in 3 months (AU)

Hemangioma lobular capilar inusual en un paciente pediátrico. Reporte de caso y revisión de literatura / Unusual capillary lobular hemangioma in a pediatric patient. Case report and literature review

Lobular capillary hemangioma or pyogenic granuloma is a benign non-neoplastic lesion that is mainly presented as a tissue growth in response to irritation or trauma. It is located on the skin or on the mucous membrane, with the oral mucosa being the most frequent, with the gingiva standing out, but also appearing in other places such as the lips, buccal mucosa, palate and tongue, the latter being a very unusual location. This is a report of the case of a pediatric patient who underwent a surgical procedure of frenotomy, and who subsequently presented a lesion due to trauma possibly as a consequence of local anes-thesia, which forced an excisional biopsy, the histopathological diagnosis being capillary lobular hemangioma or pyogenic granuloma. Likewise, a literature review of this type of pathology is presented, with emphasis on its location in the tongue.

Synovium and blood capillaries at the femoral attachment of anterior cruciate ligament are significantly abundant than those at the tibial attachment / Sinovial y capilares sanguíneos en la inserción femoral del ligamento cruzado anterior son significativamente más abundantes que los de la inserción tibial

SUMMARY: The anterior cruciate ligament (ACL) is a ligament that mainly controls the anterior and rotational mobility of the knee joint, and its surface is covered by a synovial membrane with large number of blood vessels. In general, nutritional supply to the ligament is from many capillaries in the adjacent synovium. However, statistical studies of the capillaries distributed to the ACL are insufficient. In this study, we examined cross-sectional histological images of the femoral attachment (femoral level), middle level of the tendon (middle level), and tibial attachment (tibial level) of the ACL and statistically analyzed blood capillary distribution among the three levels. The ACLs of 10 cadavers were divided into 5 equal sections, and 4mm-thick paraffin sections were made at the femoral level, middle level, and tibial level, and then hematoxylin-eosin (HE) staining were performed. The area of each transverse section was measured using Image-J 1.51n (U. S. National Institutes of Health, Bethesda, MD, USA). Fiber bundles of the ACL were relatively small and sparse in cross-sectional area at the femoral level and became larger and denser toward the tibial level. Many blood levels. The synovium at the attachment of ACL covered the surface of the fiber bundle and also penetrated deeply between the fiber bundles. In particular, the blood capillaries were densely distributed in the synovium at the femoral attachment rather than another two levels. Indeed, the number of capillaries were also most abundant in the femoral level. The cross-sectional ACL area at the femoral level is significantly small, however, the blood capillaries were most abundant. Therefore, when the ACL is injured, its reconstruction with preservation of the femoral ligamentous remnant may be clinically useful for remodeling of the grafted tendon.

El ligamento cruzado anterior (LCA) es un ligamento que controla principalmente la movilidad anterior y rotacional de la articulación de la rodilla, y su superficie está cubierta por una membrana sinovial con gran cantidad de vasos sanguíneos. En general, el suministro de nutrientes al ligamento proviene de muchos capilares en la sinovial adyacente. Sin embargo, los estudios estadísticos de los capilares distribuidos en el LCA son insuficientes. En este estudio, examinamos imágenes histológicas trans- versales de la inserción femoral (nivel femoral), el nivel medio del tendón (nivel medio) y la inserción tibial (nivel tibial) del LCA y analizamos estadísticamente la distribución de los capilares sanguíneos entre los tres niveles. Los LCA de 10 cadáveres se dividieron en 5 secciones iguales y se realizaron cortes en parafina de 4 µm de espesor a nivel femoral, medio y tibial, y luego se realizó tinción con hematoxilina-eosina (HE). El área de cada sección transversal se midió utilizando Image-J 1.51n (Institutos Nacionales de Salud de EE. UU., Bethesda, MD, EE. UU.). Los haces de fibras del LCA eran relativamente pequeños y escasos en el área de la sección transversal a nivel femoral y se hicieron más grandes y más densos hacia el nivel tibial. La membrana sinovial en la unión del LCA cubría la superficie del haz de fibras y también penetraba profundamente entre entre los haces de fibras. En particular, los capilares sanguíneos estaban densamente distribuidos en la unión femoral de la sinovial respecto a los otros dos niveles. De hecho, el número de capilares también fue más abundante a nivel femoral. El área transversal del LCA a nivel femoral era significativamente pequeña, sin embargo, los capilares sanguíneos fueron los más abundantes. Por lo tanto, cuando hay una lesión del LCA su reconstrucción con preservación del ligamento femoral remanente puede ser clínicamente útil para remodelar el tendón injertado.

Microcirculatory changes as a hallmark of aging in the heart and kidney / Cambios microcirculatorios como sello distintivo del envejecimiento en el corazón y riñón

SUMMARY: Changes in the microcirculation of multiple tissues and organs have been implicated as a possible mechanism in physiological aging. In particular, vascular endothelial growth factor is a secretory protein responsible for regulating angiogenesis via altering endothelial proliferation, survival, migration, extracellular matrix degradation and cell permeability. The aim of the present study was to evaluate the role of vascular endothelial growth factor in the progression of morphological alterations caused by physiological aging in the heart and kidney and to examine its relation to changes in capillary density. We used two age groups of healthy Wistar rats - 6- and 12-month- old. The expression of vascular endothelial growth factor was examined through immunohistochemistry and immunofluorescence and assessed semi-quantitatively. Changes in capillary density were evaluated statistically and correlated with the expression of vascular endothelial growth factor. We reported stronger immunoreactivity for vascular endothelial growth factor in the left compared to the right ventricle and also observed an increase in its expression in both ventricles in older animals. Contrasting results were reported for the renal cortex and medulla. Capillary density decreased statistically in all examined structures as aging progressed. The studied correlations were statistically significant in the two ventricles in 12-month-old animals and in the renal cortex of both age groups. Our results shed light on some changes in the microcirculation that take place as aging advances and likely contribute to impairment in the function of the examined organs.

Los cambios en la microcirculación de múltiples tejidos y órganos se han implicado como un posible mecanismo en el envejecimiento fisiológico. En particular, el factor de crecimiento endotelial vascular es una proteína secretora responsable de regular la angiogénesis mediante la alteración de la proliferación endotelial, la supervivencia, la migración, la degradación de la matriz extracelular y la permeabilidad celular. El objetivo del presente estudio fue evaluar el papel del factor de crecimiento del endotelio vascular en la progresión de las alteraciones morfológicas causadas por el envejecimiento fisiológico en el corazón y riñón y examinar su relación con los cambios en la densidad capilar. Utilizamos dos grupos de ratas Wistar sanas: 6 y 12 meses de edad. La expresión del factor de crecimiento del endotelio vascular se examinó mediante inmunohistoquímica e inmunofluorescencia y se evaluó semicuantitativamente. Los cambios en la densidad capilar se evaluaron estadísticamente y se correlacionaron con la expresión del factor de crecimiento del endotelio vascular. Informamos una inmunorreactividad más fuerte para el factor de crecimiento endotelial vascular en el ventrículo izquierdo en comparación con el derecho y también observamos un aumento en su expresión en ambos ventrículos en animales mayores. Se informaron resultados contrastantes para la corteza renal y la médula. La densidad capilar disminuyó estadísticamente en todas las estructuras examinadas a medida que avanzaba el envejecimiento. Las correlaciones estudiadas fueron estadísticamente significativas en los dos ventrículos en animales de 12 meses y en la corteza renal de ambos grupos de edad. Nuestros resultados arrojan luz sobre algunos cambios en la microcirculación que tienen lugar a medida que avanza el envejecimiento y probablemente contribuyan a un deterioro en la función de los órganos examinados.

Detección de pacientes con diabetes mellitus tipo 2 oculta desde las farmacias comunitarias de Valladolid. Valoración del impacto ambiental. Prueba piloto / Pilot trial on the detection of patients with undiagnosed diabetes mellitus type 2 carried out in pharmacies in Valladolid. Environmental impact assessment

Introducción: las complicaciones que puede desarrollar la DM2 y las cifras de población no diagnosticadas (6 %) ponen de manifiesto la importancia de realizar cribados a nivel poblacional. El objetivo de este trabajo es evaluar un programa de detección precoz de DM2 oculta desde la farmacia comunitaria y posterior derivación al médico para determinar el posible diagnóstico, así como evaluar el impacto ambiental de las actuaciones. Material y métodos: cuestionario Findrisc a los pacientes que, cumpliendo con los criterios de inclusión, aceptan participar en el estudio. Se realiza glucemia basal capilar si el resultado es ≥15 puntos y derivación al médico si la glucemia basal es ≥110 mg/dL. Resultados: participaron 44 farmacias. La muestra incluyó 434 usuarios. Se realizó la glucemia a 125 de los 135 pacientes con Findrisc ≥15 puntos, obteniéndose una media de 124,5 mg/dL (DE=33,6). Se de­rivaron al médico 89 pacientes de los que en 13 casos se confirmó el diagnóstico de diabetes, lo que supone un 3 % de la muestra total analizada y un 14,6 % de los derivados. Discusión: los nuevos diagnósticos (3 %) reflejan que la farmacia comunitaria es un buen punto de detección de diabetes oculta. Además, tras analizar la intervención del farmacéutico, se podría indicar su utilidad como educador sanitario, indicando hábitos de vida saludables a aquellos pacientes no susceptibles de derivación al médico. Por otra parte, sería precisa una mayor colaboración médico-farmacéutico en los cribados de diabetes (AU)

Immediate-Onset Linear Effluvium Associated With High-Density Hair Transplantation: A Series of 28 Cases. / Efluvio en línea de aparición inmediata asociado a trasplante capilar de alta densidad: descripción de 28 casos.

We describe 28 patients who experienced effluvium with previously unreported features shortly after hair transplant surgery. Notable features were as follows: a) a linear morphology; b) immediate onset (1-3 days); c) association with dense-pack grafting in areas of receding hairline at the temples (Mickey Mouse pattern); d) a progressive increase in the diameter of the hair loss line (wave-like pattern); e) in some cases, subsequent concentric linear effluvium on the crown (donut pattern); and f) other forms of previously unreported immediate-onset effluvium. The linear morphology could be the result of dense packing, which can cause perilesional hypoxia and loss of miniaturized hairs around the recipient area. Since linear hair loss can cause patient concern about graft failure, we recommend taking images of transplanted and nontransplanted areas immediately after surgery and warning patients in advance about these transient effects, which are fully reversed in 3 months.

Procedimentos estéticos com ênfase na queda capilar / Aesthetic procedures with emphasis on hair loss / Procedimientos estéticos con énfasis en la caída del cabello

A beleza está diretamente ligada ao aspecto dos cabelos, em todos os tempos e todas as culturas. O cabelo ao longo da vida é sujeito a vários tipos de mudanças, sejam elas naturais ou artificiais, conduzidas por uma vontade de mudar, muitas vezes, seja por representar uma nova fase, como também é símbolo de autocuidado, vaidade, sucesso, possuem significativa importância na aparência e autoestima das pessoas e, por isso, a queda capilar pode atingir a qualidade de vida do indivíduo. Neste sentido, o objetivo deste estudo foi avaliar procedimentos estéticos minimamente invasivos e não cirúrgicos com ênfase na queda capilar. Para tanto, foi realizada uma revisão bibliográfica integrativa, de caráter descritivo nas principais bases de dados em saúde: SciELO, Google Acadêmico, PubMed e livros de medicina, nos idiomas português, inglês e espanhol, considerando o período de 2007 a 2022. De acordo com o último censo da Sociedade Brasileira de Dermatologia, a queixa de alopecia está entre as dez mais frequentes nos consultórios dermatológicos. As doenças capilares mais importantes estão divididas em dois grupos, as cicatriciais quando a perda de cabelo é acompanhada por cicatrizes resultando em calvície permanente, e as não cicatriciais onde a calvície não é permanente levando a diminuição e o afinamento gradual do cabelo. A alopecia não cicatricial é a mais frequente e as mais comuns entre elas são a alopecia androgenética e o eflúvio telógeno. Muitos pacientes procuram tratamento para melhorar a aparência e a autoestima, que podem estar relacionados a quadros de ansiedade e depressão. Esses tratamentos devem ser individualizados, onde se deve avaliar as características individuais de cada paciente. Os tratamentos capilares estéticos podem contribuir de forma significativa para a redução da baixa autoestima, contribuindo para recuperação da autoconfiança através do crescimento capilar proporcionado pela estética. Sendo assim, conclui-se que os resultados coletados na revisão de literatura foram satisfatórios, de forma onde mostra que os medicamentos, suplementos e tratamentos estéticos na queda capilar vem evoluindo cada vez mais. Contudo, mais estudos acerca do assunto são necessários.

Beauty is directly linked to the appearance of hair, in all times and all cultures. Hair throughout life is subject to various types of changes, whether natural or artificial, driven by a desire to change, often because it represents a new phase, as it is also a symbol of self-care, vanity, success, they have significant importance in people's appearance and self-esteem and, therefore, hair loss can affect the individual's quality of life. In this sense, the objective of this study was to evaluate minimally invasive and non- surgical aesthetic procedures with an emphasis on hair loss. To this end, an integrative bibliographic review was carried out, of a descriptive nature, in the main health databases: SciELO, Google Scholar, PubMed and medical books, in Portuguese, English and Spanish, considering the period from 2007 to 2022. According to the latest census by the Brazilian Society of Dermatology, the complaint of alopecia is among the ten most frequent complaints in dermatological offices. The most important hair diseases are divided into two groups, scarring when hair loss is accompanied by scars resulting in permanent baldness, and non-scarring where baldness is not permanent leading to gradual thinning and thinning of the hair. Non-scarring alopecia is the most frequent and the most common among them are androgenetic alopecia and telogen effluvium. Many patients seek treatment to improve their appearance and self-esteem, which may be related to anxiety and depression. These treatments must be individualized, where the individual characteristics of each patient must be evaluated. Aesthetic hair treatments can contribute significantly to reducing low self-esteem, contributing to the recovery of self-confidence through hair growth provided by aesthetics. Therefore, it is concluded that the results collected in the literature review were satisfactory, in a way that shows that medicines, supplements and aesthetic treatments in hair loss have been evolving more and more. However, more studies on the subject are needed.

Las alopecias no cicatriciales son las más frecuentes y entre ellas destacan la alopecia androgenética y el efluvio telógeno. Muchos pacientes buscan tratamiento para mejorar su aspecto y autoestima, que pueden estar relacionados con la ansiedad y la depresión. Estos tratamientos deben ser individualizados, donde se deben evaluar las características individuales de cada paciente. Los tratamientos capilares estéticos pueden contribuir significativamente a la reducción de la baja autoestima, contribuyendo a la recuperación de la confianza en uno mismo gracias al crecimiento del cabello que proporciona la estética. Por lo tanto, se concluye que los resultados recogidos en la revisión bibliográfica fueron satisfactorios, mostrando que los medicamentos, suplementos y tratamientos estéticos para la caída del cabello están evolucionando cada vez más. Sin embargo, son necesarios más estudios sobre el tema.

O dano capilar causado pelo descolorimento oxidativo é muito intenso, sendo que dois fatores são responsáveis por essa ação: primeiro, a ação direta e danosa do oxidante em diversas estruturas capilares e segundo, o dano oxidativo primário facilita o dano causado por outros agentes físicos (luz, temperatura) e químicos (tensoativos), que comumente tem ação nos cabelos. Desenvolver conceitos e tecnologias que possam tornar o oxidante específico para a melanina e por conseguinte efetuando o descolorimento sem causar danos ao fio é extremamente desejável. Neste trabalho buscaremos entender de que forma a luz visível pode aumentar a ação do oxidante sem danificar o fio colateralmente. O objetivo principal deste trabalho é demonstrar que é possível utilizar a luz visível, que é absorvida pela melanina, para tornar esse pigmento mais suscetível ao agente oxidante e desta forma, permitir que o descolorimento seja realizado com concentrações pequenas de oxidante. Também almejamos desenvolver métodos de análises por microscopia ótica de fluorescência e de reflexão para mensurar o dano nas estruturas dos fios processados com oxidante e na presença ou ausência da luz

The capillary damage caused by oxidative discoloration is very intense, and two factors are responsible for this action: first, the direct and harmful action of the oxidant on several capillary structures and second, the primary oxidative damage facilitates the damage caused by other physical agents (light, temperature) and chemicals (surfactants), which commonly have action on the hair. Developing concepts and technologies that can make the oxidant specific to melanin and therefore discoloring without causing damage to the hair is extremely desirable. In this work we will try to understand how visible light can increase the oxidant's action without damaging the wire collaterally. The main objective of this work is to demonstrate that it is possible to use visible light, which is absorbed by melanin, to make this pigment more susceptible to the oxidizing agent and, thus, to allow the discoloration to be carried out with small concentrations of oxidizer. We also aim to develop methods of analysis by optical fluorescence and reflection microscopy to measure the damage to the structures of the threads processed with oxidizer and in the presence or absence of light

A new technique for the detection of dry weight in hemodialysis patients: Estimated pulmonary capillary wedge pressure. A tissue Doppler imaging study.

BACKGROUND AND OBJECTIVE: Fluid overload is an important factor of morbidity and mortality in hemodialysis patients. Today correct determination of dry weight (DW) remains an important issue of hemodialysis practice. Within this context, it is subjected to new method searching. The objective of this study was to calculate estimated pulmonary capillary wedge pressure (ePCWP) with Tissue Doppler Imaging (TDI) in hemodialysis patients and to evaluate its correlation with the other volume markers and to evaluate whether it can be a new method for detection of DW. MATERIALS AND METHODS: Echocardiographic, hemodynamic, and biochemical volume markers of 41 hemodialysis patients were evaluated in the pre- and post-dialysis periods. Patients were divided into two groups based on ePCWP values (Group 1 ePCWP<20mmHg, Group 2 ePCWP>20mmHg). RESULTS: In the pre-dialysis period; parameters related to volume load including ePCWP, systolic blood pressure, mean arterial pressure, pulse pressure, left atrial diameter, left atrial volume, E/é, ratio and E/Vp ratio were statistically significantly higher in Group2 compared to Group1. On the other hand, strong correlations were found between pre-dialysis ePCWP and systolic blood pressure, mean arterial pressure, pulse pressure, NT-ProBNP, left atrial diameter, E/é ratio and E/Vp ratio. CONCLUSIONS: Strong correlations found between ePCWP which was calculated with TDI and the other volume markers both in pre-dialysis and post-dialysis periods. These findings can provide a significant contribution to routine evaluating of DW in hemodialysis patients. From this aspect, the prediction of ePCWP with TDI can be a new practical and reproducible method for the determination of DW.
