Plasma Calcium Level and C-Reactive Protein Albumin Ratio Affect Severe Bleeding After Coronary Artery Bypass Grafting.

OBJECTIVE: In this study, we aimed to determine whether plasma calcium level and C-reactive protein albumin ratio (CAR) as well as other demographic and hematological markers are related in predicting severe bleeding after coronary artery bypass grafting (CABG). METHODS: A total of 227 adult patients who underwent CABG at our hospital between December 2021 and June 2022 were prospectively studied. Total amount of chest tube drainage was evaluated within the first 24 hours postoperatively or until the patient was re-explored for bleeding. The patients were divided into two groups - Group 1, patients with low amount of bleeding (n=174), and Group 2, patients with severe bleeding (n=53). Univariate and multivariate regression analyzes were performed to determine independent parameters related to severe bleeding within the first 24 hours after surgery. RESULTS: When the groups were compared in terms of demographic, clinical, and preoperative blood parameters; cardiopulmonary bypass time and serum C-reactive protein (CRP) levels were found to be significantly higher in Group 2 compared to the low bleeding group. In addition, lymphocytes, hemoglobin, calcium, albumin, and CAR were found to be significantly lower in Group 2. In multivariate analysis, calcium, albumin, CRP, and CAR were found to be independent predictors of significant association with excessive bleeding. A cut-off value of 8.7 (94.3% sensitivity and 94.8% specificity) for calcium and 0.155 (75.4% sensitivity and 80.4% specificity) for CAR predicted excessive bleeding. CONCLUSION: Plasma calcium level, CRP, albumin, and CAR can be used to predict severe bleeding after CABG.

Marcadores humorales y estudio ultrasonográfico en pacientes diabéticos con enfermedad hepática por acumulación de grasa / Humoral markers and ultrasonographic study in diabetic patients with liver disease due to fat accumulation

Introducción: La enfermedad hepática grasa no alcohólica se caracteriza por: una acumulación de grasa en el hígado en forma de triacilglicéridos, ausencia de inflamación, fibrosis y un consumo de menos de 30 grados de alcohol al día. Esta afección se asocia a la diabetes mellitus (sobre todo tipo 2), y se observa un creciente aumento en el número de consultas hospitalarias por esta causa. Objetivo: Determinar la relación de los marcadores humorales y el estudio ultrasonográfico en pacientes diabéticos con enfermedad hepática grasa no alcohólica. Métodos: Se realizó una investigación descriptiva y transversal en la Consulta Provincial de Hepatología del Hospital Universitario Clínico-Quirúrgico «Arnaldo Milián Castro», en el período de marzo 2019 a diciembre 2020. El universo de estudio estuvo conformado por 89 pacientes (con edades mayores o iguales a 19 años, de ambos sexos); la muestra estuvo constituida por 66 pacientes que fueron seleccionados por muestreo no probabilístico. Resultados: Predominaron los pacientes con edades entre 40 y 59 años, masculinos, de piel blanca, y procedencia urbana. El grado de esteatosis predominante fue el grado 1 (leve). Los marcadores humorales (glicemia, gamma glutamil transpeptidasa, albúmina e índice de Ritis) fueron los más afectados patológicamente. Conclusiones: Los estudios ultrasonográficos mostraron una asociación estadísticamente significativa con alteración de los marcadores humorales de lesión hepática, lo cual puede alertar de una posible evolución desfavorable de esta enfermedad.

Introduction: non-alcoholic fatty liver disease is characterized by an accumulation of fat in the liver in the form of triacylglycerides, absence of inflammation, fibrosis and a consumption of less than 30 degrees of alcohol per day. This condition is associated with diabetes mellitus (especially type 2), and there is a growing increase in the number of hospital visits for this cause. Objective: to determine the relationship between humoral markers and ultrasonographic study in diabetic patients with non-alcoholic fatty liver disease. Methods: a descriptive and cross-sectional investigation was carried out in the provincial hepatology consultation at "Arnaldo Milián Castro" Clinical and Surgical University Hospital from March 2019 to December 2020. The study universe consisted of 89 patients (older than or equal to 19 years, of both genders); the sample consisted of 66 patients who were selected by non-probabilistic sampling. Results: white male patients aged between 40 and 59 years living in urban areas predominated. The predominant degree of steatosis was grade 1 (mild). Humoral markers (glycemia, gamma- glutamyl transpeptidase, albumin and De Ritis ratio) were the most pathologically affected. Conclusions: ultrasonographic studies showed a statistically significant association with changes in humoral markers of liver injury, which may alert to a possible unfavorable evolution of this disease.

Effect of an Albumin Infusion Treatment Protocol on Delayed Cerebral Ischemia and Relevant Outcomes in Patients with Subarachnoid Hemorrhage.

BACKGROUND: An institutional management protocol for patients with subarachnoid hemorrhage (SAH) based on initial cardiac assessment, permissiveness of negative fluid balances, and use of a continuous albumin infusion as the main fluid therapy for the first 5 days of the intensive care unit (ICU) stay was implemented at our hospital in 2014. It aimed at achieving and maintaining euvolemia and hemodynamic stability to prevent ischemic events and complications in the ICU by reducing periods of hypovolemia or hemodynamic instability. This study aimed at assessing the effect of the implemented management protocol on the incidence of delayed cerebral ischemia (DCI), mortality, and other relevant outcomes in patients with SAH during ICU stay. METHODS: We conducted a quasi-experimental study with historical controls based on electronic medical records of adults with SAH admitted to the ICU at a tertiary care university hospital in Cali, Colombia. The patients treated between 2011 and 2014 were the control group, and those treated between 2014 and 2018 were the intervention group. We collected baseline clinical characteristics, cointerventions, occurrence of DCI, vital status after 6 months, neurological status after 6 months, hydroelectrolytic imbalances, and other SAH complication. Multivariable and sensitivity analyses that controlled for confounding and considered the presence of competing risks were used to adequately estimate the effects of the management protocol. The study was approved by our institutional ethics review board before study start. RESULTS: One hundred eighty-nine patients were included for analysis. The management protocol was associated with a reduced incidence of DCI (hazard ratio 0.52 [95% confidence interval 0.33-0.83] from multivariable subdistribution hazards model) and hyponatremia (relative risk 0.55 [95% confidence interval 0.37-0.80]). The management protocol was not associated with higher hospital or long-term mortality, nor with a higher occurrence of other unfavorable outcomes (pulmonary edema, rebleeding, hydrocephalus, hypernatremia, pneumonia). The intervention group also had lower daily and cumulative administered fluids compared with historic controls (p < 0.0001). CONCLUSIONS: A management protocol based on hemodynamically oriented fluid therapy in combination with a continuous albumin infusion as the main fluid during the first 5 days of the ICU stay appears beneficial for patients with SAH because it was associated with reduced incidence of DCI and hyponatremia. Proposed mechanisms include improved hemodynamic stability that allows euvolemia and reduces the risk of ischemia, among others.

Baseline Severity and Inflammation Would Influence the Effect of Simvastatin on Clinical Outcomes in Cirrhosis Patients.

BACKGROUND: Simvastatin administration to decompensated cirrhosis patients improved Child-Pugh (CP) at the end of a safety trial (EST). AIM: To evaluate whether simvastatin reduces cirrhosis severity through a secondary analysis of the safety trial. METHODS: Thirty patients CP class (CPc) CPc A (n = 6), CPc B (n = 22), and CPc C (n = 2) received simvastatin for one year. PRIMARY ENDPOINT: cirrhosis severity. Secondary endpoints: health-related quality of life (HRQoL) and hospitalizations for cirrhosis complications. RESULTS: Cirrhosis severity decreased baseline versus EST only across CP score (7.3 ± 1.3 versus 6.7 ± 1.7, P = 0.041), and CPc: 12 patients lessened from CPc B to CPc A, and three patients increased from CPc A to CPc B (P = 0.029). Due to cirrhosis severity changes and differences in clinical outcomes, 15 patients completed the trial as CPc AEST and another 15 as CPc B/C. At baseline, CPc AEST showed greater albumin and high-density lipoprotein cholesterol concentrations than CPc B/C (P = 0.036 and P = 0.028, respectively). Comparing EST versus baseline, only in CPc AEST, there was a reduction in white-cell blood (P = 0.012), neutrophils (P = 0.029), monocytes (P = 0.035), and C-reactive protein (P = 0.046); an increase in albumin (P = 0.011); and a recovery in HRQoL (P < 0.030). Finally, admissions for cirrhosis complications decreased in CPc AEST versus CPc B/C (P = 0.017). CONCLUSIONS: Simvastatin would reduce cirrhosis severity only in CPc B at baseline in a suitable protein and lipid milieu, possibly due to its anti-inflammatory effects. Furthermore, only in CPc AEST would improve HRQoL and reduce admissions by cirrhosis complications. However, as these outcomes were not primary endpoints, they require validation.

Albumin-Bilirubin Score: A Novel Mortality Predictor in Valvular Surgery.

INTRODUCTION: The heart and liver are two organs that are closely related. The Albumin-Bilirubin (ALBI) score is a developed scoring system for assessing liver function. The aims of this study were to examine the correlation between preoperative ALBI score and pulmonary artery pressure and to investigate its ability to predict heart valve surgery mortality outcomes. METHODS: The data of 872 patients who underwent isolated and combined heart valve surgery from 2014 to 2021 were retrospectively screened. In the preoperative period, 152 patients with laboratory tests including albumin and total bilirubin were found and analyzed retrospectively. Thirteen of these patients were excluded from the study. The remaining 139 patients were included in the analysis. Baseline demographic data, echocardiography data, performance status, laboratory data, operative data, and postoperative status were collected. The optimal cutoff value of preoperative ALBI score was calculated. RESULTS: The cutoff for ALBI scores was calculated as -2.44 to predict in-hospital mortality (sensitivity = 75.0%, specificity = 70%). Based on the cutoff value, 90 patients had a low ALBI score (≤ -2.44, 64.7%) and 49 patients had a high ALBI score (> -2.44, 35.3%). High ALBI score was associated with an increased incidence of acute kidney injury and in-hospital mortality, and a positive correlation was found between ALBI score and pulmonary artery pressure. CONCLUSION: In patients with valvular surgery, high ALBI score was an independent prognostic factor of in-hospital mortality and acute kidney injury. It is easily measurable and a cost-effective way to predict mortality.

A Relação entre a Relação Ácido Úrico/Albumina e a Espessura Média-Intimal da Carótida em Pacientes com Hipertensão / The Relationship between Uric Acid/Albumin Ratio and Carotid Intima-Media Thickness in Patients with Hypertension

Resumo Fundamento A hipertensão causa inflamação subendotelial e disfunção na aterosclerose resultante. A espessura média-intimal da carótida (EMIC) é um marcador útil de disfunção endotelial e aterosclerose. A razão ácido úrico/albumina (RUA) emergiu como um novo marcador para prever eventos cardiovasculares. Objetivo Nosso objetivo foi investigar a associação da RUA com a EIMC em pacientes hipertensos. Método Duzentos e dezesseis pacientes hipertensos consecutivos foram incluídos neste estudo prospectivo. Todos os pacientes foram submetidos a ultrassonografia de carótida para classificar baixos (EMIC < 0,9 mm) e altos (EMIC≥0,9 mm) grupos de EMIC. A capacidade preditiva da RUA para EMIC alta foi comparada com o índice de inflamação imune sistêmica (IIS), razão neutrófilo/linfócito (RNL), razão plaqueta/linfócito (RPL) e razão proteína C reativa/albumina (RCA). Um valor de p bilateral <0,05 foi aceito como estatisticamente significativo. Resultados Os pacientes com EMIC alta eram mais velhos e tinham maior RUA, IIS, RNL e RCA do que baixo EMIC. Idade, RUA, IIS, RNL e RCA, mas não RPL, foram associados a EMIC alta. Na análise multivariada, idade, PCR, IIS e RUA foram preditores independentes de EMIC alta. A capacidade de discriminação de RUA foi maior do que ácido úrico, albumina, IIS, RNL e RCA, e RUA teve um ajuste de modelo maior do que essas variáveis. RUA teve maior melhoria aditiva na detecção de EMIC alta do que outras variáveis, conforme avaliado com melhoria de reclassificação líquida, MDI e estatísticas C. RUA também foi significativamente correlacionada com EMIC. Conclusão RUA pode ser usado para prever EMIC alta e pode ser útil para estratificação de risco em pacientes hipertensos.

Abstract Background Hypertension causes subendothelial inflammation and dysfunction in resulting atherosclerosis. Carotid intima-media thickness (CIMT) is a useful marker of endothelial dysfunction and atherosclerosis. The uric acid to albumin ratio (UAR) has emerged as a novel marker for predicting cardiovascular events. Objective We aimed to investigate the association of UAR with CIMT in hypertensive patients. Methods Two hundred sixteen consecutive hypertensive patients were enrolled in this prospective study. All patients underwent carotid ultrasonography to classify low (CIMT < 0.9 mm) and high (CIMT ≥ 0.9 mm) CIMT groups. The predictive ability of UAR for high CIMT was compared with systemic immune inflammation index (SII), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and C-reactive protein/albumin ratio (CAR). A two-sided p-value <0.05 was accepted as statistically significant. Results Patients with high CIMT were older and had higher UAR, SII, NLR, and CAR than low CIMT. Age, UAR, SII, NLR, and CAR, but not PLR, were associated with high CIMT. In multivariable analysis, age, CRP, SII, and UAR were independent predictors of high CIMT. The discrimination ability of UAR was higher than uric acid, albumin, SII, NLR, and CAR, and UAR had a higher model fit than those variables. UAR had higher additive improvement in detecting high CIMT than other variables, as assessed with net-reclassification improvement, IDI, and C-statistics. UAR was also significantly correlated with CIMT. Conclusion UAR might be used to predict high CIMT and might be useful for risk stratification in hypertensive patients.

Determining the relationship between serum acute phase reactants and cervical premalignant lesions: a cohort study

Abstract BACKGROUND: Acute phase reactants play a role in the progression and prognosis of many malignant and premalignant tumors. This study investigated the diagnostic value of certain reactants as markers for cervical premalignant lesions. OBJECTIVES: Despite advanced screening and vaccination programs, cervical cancer remains a serious health problem worldwide. We aimed to determine the possible relationship between premalignant cervical disease and serum acute phase reactant levels. DESIGN AND SETTING: This study included 124 volunteers who underwent cervical cancer screening. We divided the patients into three groups according to cervical cytology and histopathological findings as follows: no cervical lesion, low-grade neoplasia, or high-grade neoplasia. METHODS: We included women aged 25-65 years with benign smear or colposcopy results, low- and high-grade squamous intraepithelial lesions. The benign group was based only on cytology findings, whereas the other groups were based on histopathology findings. Demographic data and serum albumin, fibrinogen, ferritin, and procalcitonin levels were evaluated in the three groups. RESULTS: We found significant differences among the three groups in terms of age, albumin level, albumin/fibrinogen ratio, and procalcitonin level. The regression analysis revealed lower serum albumin levels in the low- and high-grade squamous intraepithelial lesion groups compared with the benign group. CONCLUSION: This is the first study to evaluate the importance of serum inflammatory markers in cervical intraepithelial lesions. Our results indicate that serum albumin level, albumin/fibrinogen ratio, procalcitonin level, and neutrophil values differ among cervical intraepithelial lesions.

Plasma Calcium Level and C-Reactive Protein Albumin Ratio Affect Severe Bleeding After Coronary Artery Bypass Grafting

ABSTRACT Objective: In this study, we aimed to determine whether plasma calcium level and C-reactive protein albumin ratio (CAR) as well as other demographic and hematological markers are related in predicting severe bleeding after coronary artery bypass grafting (CABG). Methods: A total of 227 adult patients who underwent CABG at our hospital between December 2021 and June 2022 were prospectively studied. Total amount of chest tube drainage was evaluated within the first 24 hours postoperatively or until the patient was re-explored for bleeding. The patients were divided into two groups - Group 1, patients with low amount of bleeding (n=174), and Group 2, patients with severe bleeding (n=53). Univariate and multivariate regression analyzes were performed to determine independent parameters related to severe bleeding within the first 24 hours after surgery. Results: When the groups were compared in terms of demographic, clinical, and preoperative blood parameters; cardiopulmonary bypass time and serum C-reactive protein (CRP) levels were found to be significantly higher in Group 2 compared to the low bleeding group. In addition, lymphocytes, hemoglobin, calcium, albumin, and CAR were found to be significantly lower in Group 2. In multivariate analysis, calcium, albumin, CRP, and CAR were found to be independent predictors of significant association with excessive bleeding. A cut-off value of 8.7 (94.3% sensitivity and 94.8% specificity) for calcium and 0.155 (75.4% sensitivity and 80.4% specificity) for CAR predicted excessive bleeding. Conclusion: Plasma calcium level, CRP, albumin, and CAR can be used to predict severe bleeding after CABG.

Clinical significance of sarcopenia in patients undergoing treatment for gastric cancer

SUMMARY OBJECTIVE: The aim of this study was to investigate the impact of sarcopenia on prognosis in patients with gastric cancer in order to explore the relationship between sarcopenia and postoperative complications as well as durations of hospital stay and intensive care unit. METHODS: A total of 175 patients who visited the oncology clinic between 2017 and 2022 with respect to their radiological images, demographic data, and laboratory parameters were perused. The OsiriX software was used to measure the skeletal muscle area that was divided by the body height in order to obtain the skeletal muscle index. RESULTS: A total of 50.28% of 175 patients (41 females and 134 males, with a mean age of 63.5 years) who met the inclusion criteria in the study were sarcopenic. Significant differences appeared between sarcopenic and non-sarcopenic patients with respect to durations of both hospital stay (p<0.01) and intensive care unit stay (p<0.01) (multivariate analysis). Furthermore, patients with sarcopenia had significantly frequent postoperative complications in comparison with those without sarcopenia. Among the patients with sarcopenia, decreased levels of hemoglobin and albumin as well as lymphocytes were encountered in terms of inflammatory markers; nevertheless, no significant differences were determined among other inflammatory markers. CONCLUSION: In patients undergoing treatment for gastric cancer, sarcopenia increases postoperative complications and prolongs hospital and intensive care stays during the treatment process.

Uso de albúmina a largo plazo en el paciente cirrótico. Revisión sistemática / Long-term use of albumin in the cirrhotic patient. Systematic review

Introducción. La cirrosis constituye la etapa final de la enfermedad hepática crónica, con una alta mortalidad, y puede deberse a diferentes etiologías. La albúmina tiene tres indicaciones bien establecidas: la prevención de la disfunción circulatoria inducida por paracentesis, la peritonitis bacteriana espontánea y el síndrome hepatorrenal, sin embargo, su uso a largo plazo es controvertido. El objetivo de esta revisión fue identificar si el uso prolongado de la albúmina tiene efectos beneficiosos en el tratamiento de pacientes cirróticos. Metodología. Se realizaron búsquedas en la base de datos de PubMed, empleando los siguientes términos: ("Liver Cirrhosis"[Mesh]) AND ("Serum Albumin"[Mesh] OR "Serum Albumin, Human"[Mesh]). Se excluyeron los artículos que no cumplieron con la temática y aquellos que tenían más de 5 años de antigüedad, a excepción de aquellos relevantes para la revisión. Resultados. Se ha demos-trado en varios estudios realizados en los últimos 4 años, que la administración prolongada de albúmina reduce la mortalidad en el paciente cirrótico. Además, resulta en una disminución en ingresos hospitalarios por complicaciones de la cirrosis, disminución de la necesidad de para-centesis y menor uso de albúmina para otras indicaciones ya establecidas, lo que contrarresta los costos derivados de la terapia. Conclusión. Se concluye con base en la evidencia presenta-da, que el uso de albúmina a largo plazo podría resultar beneficioso en pacientes con cirrosis hepática descompensada. No obstante, es necesario abordar otros aspectos de la terapia en estudios posteriores

Introduction. Cirrhosis is the final stage of chronic liver disease, has a high mortality and can be due to different etiologies. Albumin has three well-established indications: prevention of circulatorydysfunction induced by paracentesis, spontaneous bacterial peritonitis, and hepatorenal syndrome, however, its long-term use is controversial. The objective of this review was to identify if the prolonged use of albumin has beneficial effects in the treatment of cirrhotic patients. Methodology. PubMed database was searched using the following terms: ("Liver Cirrhosis"[Mesh]) AND ("Serum Albumin"[Mesh] OR "Serum Albumin, Human"[Mesh]). Articles that did not meet the topic and those that were more than 5 years old were excluded, except for those relevant to the review. Results.It has been shown in several studies within the previous 4 years, that prolonged administration of albumin reduces mortality in cirrhotic patients. In addition, it results in a decrease in hospital ad-missions due to complications of cirrhosis, a decrease in the need for paracentesis and less use of albumin for other established indications, which offsets the costs derived from therapy. Conclusion. It is concluded based on the evidence presented, that the long-term use of albumin could be beneficial in patients with decompensated liver cirrhosis. However, other aspects of the therapy need to be addressed in further studies

Relación entre parasitosis intestinal y parámetros bioquímicos y hematológicos en niños de la comunidad Las Trincheras, Venezuela

Objetivo Relacionar la parasitosis intestinal con los parámetros bioquímicos y hematológicos en niños de la comunidad de Las Trincheras. Métodos Se trató de un estudio de tipo descriptivo-correlacional y diseño de campo, transversal, comparativo en 31 niños seleccionados de forma intencional. Se realizó análisis coproparasitológico directo con solución salina, lugol y Kato. Las proteínas totales y albúmina se determinaron por método colorimétrico. Los parámetros hematológicos fueron evaluados por método manual y el grado de eosinofilia se calculó con base en el valor absoluto de eosinófilos. Resultados El 79,5% (31/39) de los niños estudiados presentaron una o más especies de parásitos con predominio de Blastocystis spp. y Endolimax nana en un 74,2%. Ambos sexos fueron afectados por igual (p>0,05) y mostraron un estado nutricional normal en relación con el IMC/E, principalmente en el grupo de edad de 7 a 10 años. Los valores de proteínas totales, albúmina, hemoglobina, hematocrito y leucocitos fueron normales en la mayoría de los niños. La neutrofilia y linfopenia fue una condición observada en el 45,2% de los poliparasitados mientras que la eosinofilia leve (19,4%) fue mucho más frecuente en los niños monoparasitados. Conclusiones En la muestra de estudio no existe asociación estadísticamente significativa entre los parámetros hematológicos, bioquímicos y la presencia de parasitosis intestinal, no obstante, las variaciones hematológicas, principalmente neutrofilia, linfopenia y eosinofilia leve presentes en los niños poliparasitados por geohelmintos, son un factor asociado a la helmintiasis intestinal y podrían indicar hábitos de fecalismo dentro de la comunidad.

Objective To relate intestinal parasitosis with biochemical and hematological parameters in children from Las Trincheras community. Methods This was a descriptive-correlational study and cross-sectional, comparative field design in 31 children intentionally selected. Direct coproparasitological analysis was performed with saline, lugol and Kato. Total proteins and albumin were determined by colorimetric method. Hematological parameters were evaluated by manual method and the degree of eosinophilia was calculated based on the absolute value of eosinophils. Results 79.5% (31/39) of the children studied presented one or more species of parasites with a predominance of Blastocystis spp. and Endolimax nana in 74.2%. Both sexes were affected equally (p>0.05) and showed a normal nutritional estatus in relation to BMI/A, mainly in the age group of 7 to 10 years. Total protein, albumin, hemoglobin, hematocrit and leukocyte values were normal in most children. Neutrophilia and lymphopenia were an observed condition in 45.2% of polyparasitic, while mild eosinophilia (19.4%) was much more frequent in monoparasitic children. Conclusions In the study sample there is not statistically significant association between hematological and biochemical parameters and the presence of intestinal parasitosis, despite the hematological variations, mainly neutrophilia, lymphopenia, and mild eosinophilia present in children who are polyparasitic by geohelminths, are a factor associated with intestinal helminthiasis and could indicate fecal habits within the community.

Correlation between productive and interior traits of steers of different genotypes / Correlação entre traços produtivos e interiores de bois de diferentes genótipos

The objective was to study the productive and biological traits of young cattle of the Kalmyk breed and its crosses. The experiment was conducted on 4 groups of steers, 10 heads each, at OAO Shurupovskoe, Frolovsky District, Volgograd Region. The experimental steers were kept in rooms separately in groups on a deep bed of straw and had free access to walking yards with mounds. The hemoglobin content and the numbers of erythrocytes and leukocytes were determined on a Medonic CA 530 hematological analyzer. The total protein in blood serum and protein fractions were found on an automatic biochemical analyzer Stat Faks 1904. The digital experimental data were processed by the variation statistics method in terms of the significance of the compared parameters using the Student's test accepted in biology and animal science. The study evidenced that the contents of morphological elements and proteins in blood reflected the metabolism and potential for crossbred steers to gain muscle mass.

Os bois experimentais foram mantidos em quartos separados em grupos em uma cama de palha profunda e tiveram livre acesso a pátios de caminhada com montes. O conteúdo de hemoglobina e o número de eritrócitos e leucócitos foram determinados em um analisador hematológico Medonic CA 530. A proteína total em soro sanguíneo e frações proteicas foram encontradas em um analisador bioquímico automático Stat Faks 1904. Os dados experimentais digitais foram processados pelo método de estatística de variação em termos da significância dos parâmetros comparados usando o teste de Student aceito em biologia e ciência animal. O estudo evidenciou que o conteúdo de elementos morfológicos e proteínas no sangue refletia o metabolismo e o potencial de bois cruzados para ganhar massa muscular.

Comparison of C-reactive protein and C-reactive protein-to-albumin ratio in predicting mortality among geriatric coronavirus disease 2019 patients

SUMMARY OBJECTIVE: The aim of this study was to evaluate and compare C-reactive protein and C-reactive protein-to-albumin ratio performances in predicting mortality of geriatric patients who visited the emergency department. METHODS: The data of patients with COVID-19 and aged 65 years and above, who visited emergency department during the study period, were retrospectively analyzed. The data were obtained from an electronic-based hospital information system. The area under the receiver operating characteristic curve and the area under the curve were used to assess each cutoff value discriminatory for predicting mortality. RESULTS: The mean age of the population included in this study was 76 (71-82) years, while 52.7% were males. The sensitivity, specificity, and area under the curve values for C-reactive protein in terms of mortality were calculated as 71.01, 52.34, and 0.635%, respectively, while the sensitivity, specificity, and area under the curve values for C-reactive protein-to-albumin ratio were calculated as 75.74, 47.66, and 0.645%, respectively (p<0.001). In the pairwise comparison for the receiver operating characteristic curves of C-reactive protein and C-reactive protein-to-albumin ratio, no statistically significant difference was found. CONCLUSIONS: Geriatric patients are the "most vulnerable" patient group against the COVID-19. In this study, both C-reactive protein and C-reactive protein-to-albumin ratio were found to be successful in predicting mortality for geriatric COVID-19 patients.

Low serum levels of vitamin D significantly increase the risk of death in older adults with hip fractures: a prospective cohort / Baixos níveis séricos de vitamina D aumentam significativamente o risco de morte em idosos com fraturas de quadril: coorte prospectiva

ABSTRACT Objective: to evaluate the relationship between 25(OH)D3 levels and fatal outcome in patients over 60 years of age undergoing surgical repair of hip fractures. Methods: prospective cohort of patients undergoing surgical repair of hip fractures. At admission, 25(OH)D3 levels were measured, among other parameters. Patients were followed for at least 1 year, and incident mortality was recorded. Results: 209 patients were included in the study, with a mean age of 79.5 ± 7.6 years among survivors and 80.7 ± 8.2 years among those who died in the first postoperative year (p=0.346). The 25(OH)D3 levels of survivors were significantly higher than those of patients who died (p=0.003). After adjusting for confounding variables, 25(OH)D3 levels below 12.5ng/mL were significant risk factors regardless of mortality (adjusted OR: 7.6; 95% CI: 2.35 to 24.56). Conclusions: our data show that serum 25(OH)D3 levels below 12.5ng/mL significantly and independently increased the risk of mortality in the first year after surgical repair of low-energy hip fracture in patients over 60 years of age in the geographic region where this study was conducted. Low albumin also showed a significant association with mortality in these patients. All other factors had no significant associations.

RESUMO Objetivo: avaliar a relação entre os níveis de 25(OH)D3 e o desfecho fatal em pacientes acima de 60 anos submetidos a correção cirúrgica de fratura de quadril. Métodos: coorte prospectiva de pacientes submetidos a correção cirúrgica de fraturas de quadril. À admissão, foram medidos os níveis de 25(OH)D3, entre outros parâmetros. Os pacientes foram acompanhados por, pelo menos, um ano e a mortalidade foi registrada. Resultados: foram incluídos 209 pacientes no estudo, com média de idade de 79,5 ± 7,6 anos entre os sobreviventes e 80,7 ± 8,2 anos entre os que morreram no primeiro ano de pós-operatório (p=0,346). Os níveis de 25(OH)D3 dos sobreviventes foram significativamente maiores do que os dos pacientes que morreram (p=0,003). Após o ajuste para variáveis de confusão, níveis de 25(OH)D3 abaixo de 12,5ng/mL foram fator de risco significativo, independentemente da mortalidade (OR ajustado 7,6; IC 95% 2,35 24,56). Conclusões: níveis séricos de 25(OH)D3 abaixo de 12,5ng/mL aumentaram significativa e independentemente o risco de morte no primeiro ano após o reparo cirúrgico de fratura de quadril de baixa energia em pacientes com mais de 60 anos de idade na região geográfica onde este estudo foi realizado. A albumina baixa também teve associação significativa com a mortalidade nesses pacientes. Todos os outros fatores não tiveram associações significativas.

Sarcopenia and blood albumin: A systematic review with meta-analysis / Sarcopenia y albúmina sanguínea: revisión sistemática con metaanálisis

Sarcopenia is characterized by loss of muscle mass during aging, which can have consequences for the individuals' health. There are many ways to detect it, among them, with the use of blood biomarkers such as albumin, although the association between the two has not been confirmed yet. This review synthesizes the knowledge on the association between sarcopenia and serum albumin among elderly individuals through a systematic review and meta-analysis focused on the etiology and risk factors. We used the Joanna Briggs Institute software for the review and conducted a search in MEDLINE, Embase, CINAHL, and LILACS databases while two reviewers conducted an independent manual search. EpiDat, version 3.1 was used for the meta-analysis; mean differences with the albumin scores disaggregated by sarcopenia were analyzed by the random-effects model. The degree of heterogeneity was assessed with the DerSimonian and Laird Q test. We analyzed 630 articles and finally included 14 in the review. Higher blood albumin levels were found in the meta-analysis, which was statistically significant among the elderly adults who did not present sarcopenia compared to those who did. Although there are studies exploring the association between albumin and sarcopenia, there is a need to continue evaluating its association with biological markers and comparing them to verify which can be used to detect sarcopenia among the elderly.

La sarcopenia se caracteriza por la pérdida de musculatura durante el envejecimiento, lo que puede traer consecuencias para la salud. Se detecta de diversas formas, una de ellas, el uso de biomarcadores sanguíneos como la albúmina, aunque todavía no se ha establecido dicha asociación de forma definitiva. Esta revisión sistemática y metaanálisis resume el conocimiento sobre la asociación entre sarcopenia y albúmina sérica en los adultos mayores, centrada en la etiología y los factores de riesgo. La revisión se hizo utilizando el programa del Joanna Briggs Institute y la búsqueda incluyó las bases de datos Medline, Embase, CINAHL, y LILACS; la búsqueda manual estuvo a cargo de dos revisores de forma independiente. Para el metaanálisis, se utilizó el programa EpiDat, versión 3.1; las diferencias de medias en los puntajes de lbúmina desagregados por sarcopenia se analizaron mediante el modelo de efectos aleatorios. El grado de heterogeneidad se evaluó con la prueba Q de DerSimonian y Laird. Se analizaron 630 artículos, de los cuales 14 se incluyeron en la revisión. En el metaanálisis, se evidenciaron mayores cantidades de albúmina sanguínea en los adultos mayores que no presentaron sarcopenia frente a los que sí, una diferencia con significación estadística. Aunque hay estudios en los que se explora la asociación entre albúmina y sarcopenia, persiste la necesidad de evaluar la asociación entre los marcadores biológicos, comparándolos entre sí para determinar cuáles pueden utilizarse en la detección de sarcopenia en el adulto mayor.

A Associação da Relação Proteína C-Reativa/Albumina em Pacientes com Ectasia da Artéria Coronária Isolada / Association of C-Reactive Protein to Albumin Ratio in Patients with Isolated Coronary Artery Ectasia

Resumo Fundamento A ectasia da artéria coronária (EAC) é definida como a dilatação difusa ou localizada do lúmen da artéria coronária com diâmetro de 1,5 a 2,0 vezes o diâmetro da artéria coronária normal adjacente. A relação proteína C-reativa/albumina (CAR, sigla em inglês) é um marcador inflamatório útil que tem sido documentado em doença arterial coronariana. Objetivo Analisar a associação entre a EAC e a CAR. Métodos Um protocolo caso-controle foi utilizado neste estudo. Foram incluídos 102 pacientesconsecutivos com EAC isolada sem estenose (56 homens e 46 mulheres; idade média de 60,4 ± 8,8 anos). O grupo controle era constituido pelo mesmo número de pacientes pareados por sexo e idade com artérias coronárias normais (55 homens e 47 mulheres; idade média de 61,2 ± 9,1 anos). Características clínicas, achados laboratoriais e histórico de uso de medicamentos foram registrados. Foram realizados teste t de Student, teste U de Mann-Whitney, teste do qui-quadrado, análise de regressão linear e logística. Foi considerado estatisticamente significativo p bilateral < 0,05. Resultados A CAR estava aumentada nos pacientes com EAC em comparação com os controles (32 e 16; p < 0,001). Além disso, foi verificado que a CAR era um preditor independente da EAC (razão de chances = 2,202; intervalo de confiança 95%, 1,184 - 5,365; p < 0,001). Conclusão No presente estudo, determinamos que os níveis da CAR estavam significativamente mais altos no grupo EAC que no grupo controle e a CAR estava significativamente correlacionada com a EAC.

Abstract Background Coronary artery ectasia (CAE) is defined as diffuse or localized dilatation of coronary artery lumen with a diameter of 1.5 to 2.0 times the adjacent normal coronary artery. The C-reactive protein to albumin ratio (CAR) is a useful inflammatory marker, which has been documented in coronary artery disease. Objective To analyze the association of CAE and CAR. Methods A case-control protocol was used in this study. We included 102 consecutive patients with isolated CAE without stenosis (56 men and 46 women; mean age 60.4 ± 8.8 years). The control subjects consisted of an equal number of sex and age matched patients with normal coronary arteries (55 men and 47 women; mean age 61.2 ± 9.1 years). Clinical features, laboratory findings, and medication use history were recorded. Student's t test, Mann-Whitney U test, chi-square test, and linear and logistic regression analysis were performed. A 2-sided p < 0.05 was statistically considered significant. Results The CAR was increased in patients with CAE compared to the controls (32 and 16; p < 0.001). In addition, the CAR was found to be an independent predictor of CAE (OR = 2.202; 95% CI 1.184 - 5.365; p < 0.001). Conclusion In the present study, we determined that CAR levels were significantly higher in the CAE group than in the control group, and the CAR was significantly correlated with CAE.

Predictive values of C-reactive protein/albumin ratio in new-onset atrial fibrillation after coronary artery bypass grafting

SUMMARY OBJECTIVE This study aimed to investigate the predictive value of the newly defined C-Reactive Protein (CRP)/Albumin Ratio (CAR) in determining the development of atrial fibrillation (AF) in comparison with other inflammatory markers, such as Neutrophil/Lymphocyte (N/L) Ratio and Platelet/Lymphocyte (P/L) Ratio, in patients undergoing Coronary Artery Bypass Grafting (CABG) surgery. METHODS The population of this observational study consisted of 415 patients undergoing CABG. The study cohort was subdivided into two groups based on the development of AF. Complete blood counts, serum CRP, and serum albumin levels were evaluated before the CABG. The CAR, N/L, and P/L ratios of all the patients were calculated. Predictors of postoperative AF were determined by multiple logistic regression analysis (MLRA). RESULTS During follow-up, 136 patients (32.8%) developed postoperative AF. With MLRA, independent risk factors for postoperative AF were determined as follows: fasting glucose level (OR: 1.01; 95 % CI: 1.00-1.01, P <0.001), age (OR: 1.12; 95 % CI: 1.07-1.17, P <0.001), left ventricle ejection fraction (OR: 0.90; 95 % CI: 0.87-0.94, P <0.001), male gender (OR: 3.32; 95 % CI: 1.39-7.90, P = 0.007), 24-hour drainage amount (OR: 1.004; 95 % CI: 1.002-1.005, P <0.001), and CAR (OR: 1.82; 95 % CI: 1.53-2.16, P <0.001). Receiver Operating Characteristic curve analysis showed that CAR (C-statistic: 0.75; 95% CI: 0.71-0.79, p< 0.001) was a significant predictor of AF. CONCLUSION Novel inflammatory marker CAR can be used as a reliable marker to predict the development of AF following CABG.

RESUMO OBJETIVO Este estudo teve como objetivo investigar o valor preditivo da recém-definida relação entre Proteína C-Reativa (PCR) e Albumina (CAR) na determinação do desenvolvimento de Fibrilação Atrial (FA) em comparação com outros marcadores inflamatórios, como proporção de Neutrófilos para Linfócitos (N/L) e relação Plaquetas/Linfócitos (P/L) em pacientes submetidos à Cirurgia de Revascularização do Miocárdio (CRM). MÉTODOS A população deste estudo observacional foi composta por 415 pacientes submetidos à cirurgia de revascularização do miocárdio. A coorte do estudo foi subdividida em dois grupos de acordo com o desenvolvimento da FA. Contagens sanguíneas completas, PCR sérica e albumina sérica foram obtidas antes da CRM. Os valores de CAR, relação N/L e relação P/L foram calculados. Os preditores de FA pós-operatória foram determinados por análise de regressão logística múltipla. RESULTADOS Durante o acompanhamento, 136 pacientes (32,8%) desenvolveram FA pós-operatória. Com análise de regressão logística múltipla, foram determinados os fatores de risco para FA pós-operatória: glicemia de jejum (OR: 1,01; IC 95%: 1,00-1,01, p<0,001), idade (OR: 1,12; IC 95%: 1,07-1,17, p<0,001), fração de ejeção do ventrículo esquerdo (OR: 0,90; IC 95%: 0,87-0,94, p<0,001), sexo masculino (OR: 3,32; IC 95%: 1,39-7,90, p=0,007), quantidade de drenagem de 24 horas (OR: 1,004; IC 95%: 1,002-1,005, p<0,001), CAR (OR: 1,82; IC 95%: 1,53-2,16, p<0,001). A análise da curva de características operacionais do receptor mostrou que o CAR (estatística C: 0,75; IC 95%: 0,71-0,79, p<0,001) foi um preditor significativo de FA. CONCLUSÃO O novo marcador inflamatório CAR é confiável para prever o desenvolvimento de FA após a operação de revascularização miocárdica.
