RESUMO
BACKGROUND: Acute kidney injury (AKI) is common in the pediatric intensive care unit (ICU) and is associated with poorer clinical outcomes. There is scarce data to support an association between nutritional status and nutrient delivery in critically ill pediatric patients. Therefore, the present study aimed to identify the nutritional and clinical factors associated with the development of AKI during pediatric ICU stay. METHODS: This prospective study included critically ill pediatric patients aged < 15 years who were admitted to the medical and surgical pediatric ICU. Clinical, laboratory, nutritional status, nutritional therapy parameters, and AKI data were recorded. Adjusted logistic regression was applied and expressed as odds ratio (OR) and 95% confidence interval (95%CI). P-value < 0.05 was considered significant. RESULTS: We enrolled 108 patients with a median age of 9 months (interquartile range/IQR 2.4-62.5), and 43.5% developed AKI. Sepsis/septic shock (OR 8.00; 95% CI 2.06-32.51, p = 0.003), higher severity of illness (OR 1.89; 95% CI 1.24-2.90, p = 0.003), hypoalbuminemia (OR 4.11; 95% CI 1.61-10.46, p = 0.006), edema (OR 3.42, 95% CI 1.10-10.67, p = 0.034), fluid overload (OR 3.52, 95% CI 1.56-7.96, p = 0.003), need for mechanical ventilation (OR 3.62, 95% CI 1.45-9.04, p = 0.006) and adequate protein intake (OR 0.79, 95% CI 0.63-1.00, p = 0.048) were associated with development of AKI. CONCLUSIONS: Hypoalbuminemia, need for mechanical ventilation, fluid overload, severity of illness, sepsis/septic shock, and edema were risk factors for AKI in pediatric ICU. Furthermore, adequate protein intake is associated with AKI during pediatric ICU stay, making it important to implement nutritional assessment and nutritional therapy protocols for critically ill pediatric patients.

INTRODUCTION AND OBJECTIVES: Emphysematous pyelonephritis is a life-threatening infection of the kidney and surrounding tissues associated with a high mortality rate. The aim of this study was to determine predictive factors for mortality and intensive care unit admission in patients with emphysematous pyelonephritis, and to propose a therapeutic algorithm based on current literature and our experience. METHODS: A retrospective study was done including patients with emphysematous pyelonephritis in a single center in the north of Mexico from 2011 to 2016. Demographic, clinical, microbiological and biochemical parameters, therapeutic management, and outcomes were assessed. Factors associated with admission to intensive care unit and mortality were determined. Comparison was assessed using X2 test for categorical variables, and T-test for numerical variables. Univariate and multivariate logistic regression analyses were performed. Statistical significance was set at Pâ¯<â¯.05. RESULTS: A total of 63 patients were included, of which 55 (87.3%) were females, with a mean age of 55.5⯱â¯12.2 years. The most common comorbidities were diabetes and hypertension. Escherichia coli was the most common isolated microorganism (51.7%) and extended-spectrum beta-lactamase-producing agents were reported in 31.7%. Conservative therapy was provided to 38.7%, double J stent 42.9%, open/percutaneous drainage 12.7%, and nephrectomy 25.3%. Overall mortality and intensive care admission were 20.6% and 36.5%, respectively. In the multivariate analysis, hemodynamic instability (Pâ¯=â¯.005), qSOFAâ¯≥â¯2 (Pâ¯=â¯.003), hypoalbuminemia (Pâ¯=â¯.02), and early nephrectomy (Pâ¯=â¯.002) were associated with intensive care admission. Huang scale 4 (Pâ¯=â¯.006) and early nephrectomy (Pâ¯=â¯.001) were associated to mortality. CONCLUSIONS: Emphysematous pyelonephritis is a life-threatening disease and evidence of management is based in small case series due to the low incidence of this condition. Hemodynamic instability, hypoalbuminemia, qSOFAâ¯≥â¯2, Huang scale ≥3, and early nephrectomy are associated with poor prognosis.

INTRODUCTION AND AIMS: Surgery is the main treatment for gastric cancer. D2 radical gastrectomy is associated with a variable postoperative morbidity and mortality rate worldwide. The aim of the present study was to identify the risk factors associated with the postoperative morbidity and mortality of D2 radical gastrectomy, with curative intent, for gastric cancer. MATERIALS AND METHODS: A retrospective case series was conducted, in which the medical records were reviewed of patients with gastric cancer that underwent D2 radical gastrectomy, within the time frame of January 2014 and December 2018. Univariate and multivariate analyses were carried out to identify the risk factors related to postoperative morbidity and mortality within 90 days. RESULTS: The percentages of postoperative morbidity and mortality in 691 patients were 23.3% and 3.3%, respectively. In the multivariate analysis, age ≥70 years (OR = 1.85, 95% CI: 1.25-2.76), ASA III-IV (OR = 2.06, 95% CI: 1.28-3.34), total gastrectomy (OR = 1.96, 95% CI:1.19-3.23), and pancreatosplenectomy (OR = 5.41, 95% CI: 1.42-20.61) were associated with greater postoperative morbidity, and age ≥70 years (OR = 4.92, 95% CI:1.78-13.65), lower BMI (OR = 0.81, 95% CI: 0.71-0.92), and hypoalbuminemia (OR = 0.91, 95% CI: 0.85-0.98) were associated with greater mortality in distal and total D2 radical gastrectomy. CONCLUSIONS: D2 radical gastrectomy for gastric cancer was shown to be a safe treatment, with low postoperative morbidity and mortality rates. Age ≥70 years, ASA III-IV, total gastrectomy, and pancreatosplenectomy were factors associated with a higher complication rate. Age ≥70 years, lower BMI, and hypoalbuminemia were mortality predictors in distal and total radical gastrectomy.

BACKGROUND: We aimed to determine the prevalence of hypoalbuminemia in STEC-HUS patients with hemorrhagic colitis (HC) and whether serum albumin level (SAL), leukocyte count, hematocrit and serum sodium level (SSL) are prognostic markers of HC, central nervous system disease (CNSd) and/or dialysis requirement and evaluate if hypoalbuminemia is associated with fecal protein losses. METHODS: We prospectively evaluated STEC-HUS patients treated at our institution from 9/2011 to 2/2019, analyzing the presence of HC, CNSd and dialysis requirement and SAL, SSL, leukocytes, hematocrit and α1-antitrypsin clearance. RESULTS: We evaluated 98 patients, with mean age of 33.3 months. SAL ≤ 29.5 g/l, > 24,600 leukocytes/mm3 and hematocrit > 30% behave as independent prognostic markers for HC. SAL ≤ 28 g/l, > 25,200 leukocytes/mm3 and hematocrit > 30% behave as prognostic markers for CNSd. SAL ≤ 31.6 g/l, > 13,800 leukocytes/mm3, hematocrit > 18.9% and hyponatremia (≤ 132 mEq/l) behave as prognostic markers for dialysis requirement. However, in multivariate logistic regression models, only hypoalbuminemia behaved as a risk factor for HC, CNSd and dialysis. α1-antitrypsin clearance was performed in 69 patients and was high in 9/69 (13%), only 4 with HC. No significant association was observed between α1-antitrypsin clearance and albuminemia (χ2 = 0.1076, p = 0.7429) as well as α1-antitrypsin clearance and HC (χ2 = 1.7892, p = 0.1810). CONCLUSIONS: Almost all patients with HC had hypoalbuminemia, which behaves as a risk factor for HC, CNSd and dialysis requirement. No significant association was observed between elevated α1-antitrypsin clearance and hypoalbuminemia nor between elevated α1-antitrypsin clearance and HC. These findings could be related to the small number of evaluated patients.

Local anesthetics are drugs widely used to perform peripheral nerve blocks. Signs and symptoms of toxicity may vary from mild to severe, including neuro and cardiotoxicity, with seizures and cardiac arrest. We present the case of an 85-year-old patient in total left knee replacement plan due to tibial saucer fracture, where systemic toxicity was observed by local anesthetics (LAST) after performing a femoral nerve block guided by neurostimulation and ultrasound with a solution of 20 ml of 0.525% ropivacaine + 0.6% lidocaine. As a positive data, the patient presented severe hypoalbuminemia

Introducción: La Enfermedad Renal Crónica es un problema de salud mundial. Objetivo: Determinar el comportamiento de la mortalidad en pacientes con enfermedad renal en el Instituto de Nefrología durante 2016 y 2017. Material y Métodos: Estudio observacional descriptivo transversal de pacientes fallecidos con necropsia realizada. Se registraron variables demográficas, de laboratorio, las relacionadas con la terapia de reemplazo de la función renal y con el diagnóstico anatomo-patológico. Para cada una de las variables se calcularon frecuencias absolutas y relativas. En el caso de la variable presencia de sepsis en las defunciones, fue empleada la prueba de chi-cuadrado para la bondad del ajuste, para probar la hipótesis nula H0: de igualdad de la distribución de las tres categorías de la variable. Resultados: Se estudiaron 48 fallecidos con necropsia, 48,9 por ciento del total de fallecidos en el periodo. La correspondencia clínico patológica fue 80,1 por ciento. Predominó el sexo masculino, el grupo de edad superior a 60 años y la hipertensión arterial como antecedente. El método de terapia de reemplazo renal más documentado fue la hemodiálisis, mediante catéter venoso central un 87,8 por ciento. El 61,8 por ciento de los fallecidos recibieron tratamiento hemodialítico por 3 meses o menos. La sepsis fue la segunda causa de muerte precedida por eventos cardio y cerebrovasculares; no obstante, en el análisis de la totalidad de necropsias, la infección asociada directa o indirecta a la muerte tuvo una frecuencia mayor. Conclusiones: La infección directa o indirectamente asociada a la muerte, la hipoalbuminemia y el acceso vascular mediante catéter se relacionan con la mortalidad en el periodo(AU)
Introduction: Chronic kidney disease is a health problem worldwide. Objective: To determine the behavior of mortality in patients with kidney damage in the Nephrology Institute during the years between 2016 and 2017. Material and Method: A cross-sectional descriptive observational study was conducted in 48 deceased patients who underwent necropsy. Demographic and laboratory variables were recorded, as well as those related to the type of renal function replacement therapy and the anatomopathological diagnosis. Absolute and relative frequencies were calculated for each of the variables. In the case of the variable presence of sepsis in deaths, the Chi-Square Goodness-of-Fit Test was used to test the Null Hypothesis HO: uniformity of the distribution of the three categories of the variable. Results: A total of 48 deceased were studied at necropsy, representing 48.9 percent of the total number of deaths within the period. The clinical- pathological correlation was 80.1percent. The male sex, the group over the age of 60 years, and arterial hypertension as antecedent of the disease predominated in the study. The most documented method of renal function replacement therapy was hemodialysis which was performed through central venous catheter, 87.8 percent. The 61.8 percent of deceased patients received hemodialysis treatment for 3 months or less. Sepsis represented the second cause of death preceded by cardiovascular and cerebrovascular events. However, during the analysis of all the necropsies, the direct or indirect infection associated with the death had a greater frequency. Conclusions: Direct or indirect infections associated with death, hypoalbuminemia, and the vascular access with venous catheter was related to mortality during the observed period(AU)

Envenomings by some populations of the Russell's viper (Daboia russelii) are characterized by a systemic capillary leak syndrome (CLS) which causes hemoconcentration, and is associated with the severity of envenoming. We adapted a model of CLS in mice by assessing hemoconcentration. The venom of D. russelii from Pakistan, but not that of another viperid, Bothrops asper, induced hemoconcentration and an increment in vascular permeability, being devoid of hemorrhagic activity at the doses tested. These findings reveal a dichotomous pattern of vasculotoxicity in viperid snake venoms. This difference might depend on variations in venom composition, especially regarding metalloproteinases (SVMPs), which are low in Pakistani D. russelii and high in B. asper. Inhibition of SVMPs and phospholipases A2 in D. russelii venom did not abrogate hemoconcentration. An hemoconcentration-inducing fraction was obtained by chromatography, which contains vascular endothelial growth factor (VEGF), a known potent inducer of increment in vascular permeability. Exudates collected from tissue injected with venom also induced hemoconcentration, and the effect was inhibited by antivenom. However, the amount of venom in exudate required to induce the effect is low, as compared with venom dissolved in saline solution, hence suggesting that endogenous proteins present in the exudate, probably inflammatory mediators, potentiate the effect.

BACKGROUND: Previous studies have identified hypoalbuminemia as a risk factor for negative outcome in dogs with chronic enteropathy (CE), but it has not been determined whether histopathology differs between CE dogs with and without hypoalbuminemia. OBJECTIVE: To compare histopathologic findings in dogs with biopsy-diagnosed inflammatory CE with and without hypoalbuminemia. ANIMALS: 83 dogs that had intestinal biopsy performed between January 2010-July 2015. Dogs had signs compatible with CE of at least 3-weeks' duration and no evidence of clinically relevant extra-gastrointestinal (GI) disease or potential non-GI causes of hypoalbuminemia. Dogs had primary diagnosis of inflammatory enteritis based on histopathology. METHODS: Dogs were grouped into CE with normoalbuminemia (CEN; serum albumin concentration ≥3.0 g/dL, N = 46) or chronic enteropathy with hypoalbuminemia (CEH; serum albumin concentration <3.0 g/dL, N = 37). A pathologist (SLP) blinded to the groups reviewed biopsy samples and applied the World Small Animal Veterinary Association scoring system to all samples. RESULTS: Intestinal biopsy samples from dogs in the CEH group were significantly more likely to display villous stunting, epithelial injury, crypt distension, and lacteal dilatation, and were more likely to have intraepithelial lymphocytes and lamina propria neutrophils than biopsy samples from dogs in the CEN group. Additionally, higher scores for each of the above listed histopathologic criteria were associated with a lower serum albumin concentration. CONCLUSIONS AND CLINICAL IMPORTANCE: Histopathologic features of chronic inflammatory enteropathy differ between dogs that are hypo- versus normoalbuminemic. Additional work is needed to elucidate the clinical relevance of these differences.

OBJECTIVES: Serum albumin is a strong biomarker of disease severity and prognosis in adult patients. In contrast, its value as predictor of outcome in critically ill children has not been established. We aimed to determine whether admission hypoalbuminemia is associated with outcome in a general pediatric population of critically ill patients, taking into account the inflammatory response, disease severity, and nutritional status of the patient. DESIGN: Analysis of prospectively collected database. SETTING: PICU of a teaching hospital. PATIENTS: Two hundred seventy-one patients consecutively admitted. Neonates, patients with chronic liver or kidney disease, inborn errors of metabolism, those who received prior administration of albumin solution, and readmissions were excluded. MEASUREMENTS AND MAIN RESULTS: Outcome variables were 60-day mortality, probability of ICU discharge at 60 days, and ventilator-free days. Potential exposure variables for the outcome were sex, age, nutritional status, albumin, C-reactive protein and serum lactate at admission, and Pediatric Index of Mortality 2 score. Admission hypoalbuminemia was present in 64.2% of patients. After adjustment for confounding factors, only serum lactate, Pediatric Index of Mortality 2 score, and serum albumin were associated with higher mortality: the increase of 1.0 g/dL in serum albumin at admission resulted in a 73% reduction in the hazard of death (hazard ratio, 0.27; 95% CI, 0.14-0.51; p < 0.001). The increase of 1 g/dL in serum albumin was also independently associated with a 33% rise in the probability of ICU discharge (subhazard ratio, 1.33; 95% CI, 1.07-1.64; p = 0.008) and increased ventilator-free-days (odds ratio, 1.86; 95% CI, 0.56-3.16; p = 0.005). CONCLUSIONS: Hypoalbuminemia at admission to a PICU is associated with higher 60-day mortality, longer duration of mechanical ventilation, and lower probability of ICU discharge. These associations are independent of the magnitude of inflammatory response, clinical severity, and nutritional status.

We report the case of a 22-year-old primiparous, admitted to our hospital with a 2-week history of vulvar edema that had evolved within 24 hours to the point of stopping urine flow and hindering ambulation. The only remarkable finding in relation with the edema was hypoalbuminemia for no apparent cause. The correction of hypoalbuminemia and the establishment of diuretic treatment, with the drainage of the edema allowed for a complete resolution of the edema.
