ABSTRACT

ABSTRACT Objective The present study assessed the differences in nutritional markers (albumin, transferrin, total body fat, and body mass index) and clinical complications (diarrhea, vomiting, and diet interruptions) associated with enteral nutrition. Methods This is an open-label, randomized, two-arm parallel-group controlled clinical trial. Out of 105 patients assessed for eligibility, 35 adult patients were randomly divided into two groups and followed for 28 days. The sample comprised a heterogeneous group of severely ill individuals initially treated in the intensive care units. Neurological conditions (i.e., strokes and brain tumours) were the most common reasons for hospitalization. Patients had one singularity: the clinical need for exclusive enteral nutrition therapy. One group received the diet via gastric tube and the other via a post-pyloric tube. Results The groups presented increases in the calories prescribed and administered, as well as reduced diet discontinuation. Although similar values were observed up to day 21, the post-pyloric group showed increased albumin levels compared to the gastric group on Day 28. Transferrin levels increased over time in both groups. Conclusion There were no differences in the complications recorded between groups, albeit serum albumin significantly increased in the post-pyloric group.


RESUMO Objetivo Avaliar diferenças tanto nos marcadores nutricionais (albumina, transferrina, gordura corporal e índice de massa corporal) quanto nas complicações clínicas (diarreia, vômitos e interrupções na dieta) associadas à nutrição enteral administrada através de duas vias tradicionais. Métodos Este é um ensaio clínico de tratamento, paralelo de dois braços, aberto e randomizado controlado. Dos 105 participantes avaliados para elegibilidade, 35 pacientes adultos foram divididos aleatoriamente em dois grupos e seguidos por 28 dias. A amostra foi formada por um grupo heterogêneo e gravemente enfermo, tratados inicialmente em unidades de terapia intensiva. Condições neurológicas, como acidente vascular e tumores cerebrais foram as razões principais para hospitalização. Os pacientes tinham em comum um aspecto, a saber, a necessidade clínica exclusiva de receber nutrição enteral. Um grupo recebeu a dieta via sonda gástrica e o outro através de sonda pós-pilórica. Resultados Os grupos apresentaram aumento de calorias prescritas e administradas, bem como redução da descontinuação da dieta. Embora valores semelhantes tenham sido observados até o 21° dia, o grupo pós-pilórico apresentou aumento dos níveis de albumina em relação ao grupo gástrico no dia 28. Os níveis de transferrina aumentaram ao longo do tempo em ambos os grupos. Conclusão Não houve diferenças nas complicações registradas entre os grupos, embora níveis séricos de albumina aumentaram significativamente no grupo pós-pilórico.

ABSTRACT

Resumen Introducción: Aun con adecuado protocolo de desconexión de la ventilación mecánica (DVM), el procedimiento falla en 15 a 30 % de los casos. Objetivo: Evaluar la asociación entre factores de riesgo independientes y fracaso posextubación en pacientes con DVM en una unidad de cuidados intensivos. Método: Estudio de cohorte, longitudinal, prospectivo, analítico, que incluyó pacientes sometidos a ventilación mecánica por más de 24 horas y que fueron extubados. Se obtuvieron reportes preextubación de hemoglobina, albúmina, fósforo, índice cintura-cadera y puntuación SOFA. Se definió como fracaso de extubación al reinicio de la ventilación mecánica en 48 horas o menos. Resultados: Se extubaron 123 pacientes, 74 hombres (60 %); la edad promedio fue de 50 ± 18 años. Ocurrió fracaso de extubación en 37 (30 %). Como factores de riesgo independentes se asoció hipoalbuminemia en 29 (23.8 %, RR = 1.43, IC 95 % = 1.11-1.85) e hipofosfatemia en 18 (14.6 %, RR = 2.98, IC 95 % = 1.66-5.35); se observaron dos o más factores de riesgo independientes en 22.7 % (RR = 1.51, IC 95 % = 1.14-2.00). Conclusiones: Identificar los factores de riesgo independentes antes de la DVM puede ayudar a reducir el fracaso de la extubación y la morbimortalidad asociada.


Abstract Introduction: Even with an adequate mechanical ventilation weaning (MVW) protocol, the procedure fails in 15 to 30 % of cases. Objective: To assess the association between independent risk factors (IRFs) and post-extubation failure in patients undergoing MVW in an intensive care unit. Method: Longitudinal, prospective, analytical cohort study in patients on mechanical ventilation for more than 24 hours and who were extubated. Pre-extubation reports of hemoglobin, albumin, phosphorus, waist-hip ratio and SOFA score were obtained. Extubation failure was defined as resumption of mechanical ventilation within 48 hours or less. Results: 123 patients were extubated, out of whom 74 were males (60 %); average age was 50 ± 18 years. Extubation failure occurred in 37 (30 %). Hypoalbuminemia was associated as an independent risk factor in 29 (23.8 %, RR = 1.43, 95 % CI = 1.11-1.85) and hypophosphatemia was in 18 (14.6 %, RR = 2.98, 95 % CI = 1.66-5.35); two or more IRFs were observed in 22.7 % (RR = 1.51, 95 % CI = 1.14-2.00). Conclusions: Identifying independent risk factors prior to MVW can help reduce the risk of extubation failure and associated morbidity and mortality.

ABSTRACT

Abstract Introduction: Sudden hearing loss is a significant otologic emergency. Previous studies have revealed a coexistence of sudden hearing loss with chronic inflammation. The predictive importance of C-reactive protein/albumin values as a prognostic factor has been shown in various inflammatory and tumoral conditions. Objectives: The aim of this study was to determine whether the C-reactive protein/albumin ratio in sudden hearing loss can be used for prognostic purposes and whether there is a relationship between the neutrophil/lymphocyte ratio and the C-reactive protein/albumin ratio. Methods: A retrospective examination was made of 40 patients diagnosed with idiopathic sudden hearing loss and a control group of 45 healthy subjects. The pure tone averages of all the patients were determined on first presentation and repeated at 3 months after the treatment. The patients were separated into 2 groups according to the response to treatment. The neutrophil/lynphocyte ratio and the C-reactive protein/albumin ratios were calculated from the laboratory tests. Results: The patients included 16 females and 24 males with a mean age of 44.1 ± 14.2 years and the control group was composed of 23 females and 22 males with a mean age of 42.2 ± 13.8 years. The mean C-reactive protein/albumin ratio was 0.95 ± 0.47 in the patient group and 0.74 ± 0.13 in the control group. The difference was statistically significant (p = 0.009). The mean C-reactive protein/albumin ratio was 0.79 ± 0.12 in the response to treatment group and 1.27 ± 0.72 in the non-response group, with no significant difference determined between the groups (p = 0.418). The mean neutrophil/lymphocyte ratio was 3.52 ± 3.00 in the response to treatment group and 4.90 ± 4.60 in the non-response group, with no statistically significant difference determined between the groups (p = 0.261). Conclusion: C-reactive/albumin ratio was significantly higher in patients with sudden hearing loss than in the control group. Although C-reactive protein/albumin ratio was found to be lower in sudden hearing loss patients who responded to treatment compared to those who did not, the difference between two groups was not statistically significant.


Resumo Introdução: A perda auditiva neurossensorial súbita ou surdez súbita é uma emergência otológica significativa. Estudos anteriores revelaram uma coexistência dessa condição com inflamação crônica. A importância preditiva dos valores da relação proteína C-reativa/albumina como fator prognóstico tem sido demonstrada em várias condições inflamatórias e tumorais. Objetivos: O objetivo deste estudo foi determinar se a relação proteína C-reativa/albumina na perda auditiva neurossensorial súbita pode ser usada para fins prognósticos e se existe uma associação entre as relações neutrófilo/linfócito e proteína C-reativa/albumina. Método: Foram avaliados retrospectivamente 40 pacientes com diagnóstico de perda auditiva neurossensorial súbita idiopática e um grupo controle de 45 indivíduos saudáveis. As médias de tons puros de todos os pacientes foram determinadas na primeira consulta e repetidas 3 meses após o tratamento. Os pacientes foram separados em 2 grupos de acordo com a resposta ao tratamento. As relações neutrófilo/linfócito e proteína C-reativa/albumina foram calculadas a partir de testes laboratoriais. Resultados: Os pacientes incluíam 16 mulheres e 24 homens, com média de 44,1 ± 14,2 anos, e o grupo controle por 23 mulheres e 22 homens, com média de 42,2 ± 13,8 anos. A média da relação proteína C-reativa/albumina foi de 0,95 ± 0,47 no grupo de pacientes e de 0,74 ± 0,13 no grupo controle e a diferença foi estatisticamente significante (p = 0,009). A média da relação proteína C-reativa/albumina foi de 0,79 ± 0,12 do grupo com resposta ao tratamento e de 1,27 ± 0,72 no grupo sem resposta, sem diferença significante entre os grupos (p = 0,418). A média da relação neutrófilo/linfócito foi de 3,52 ± 3,00 no grupo com resposta ao tratamento e de 4,90 ± 4,60 no grupo sem resposta, sem diferença estatisticamente significativa entre os grupos (p = 0,261). Conclusão: A relação proteína C-reativa/albumina foi significantemente maior nos pacientes com perda auditiva neurossensorial súbita do que no grupo controle. No entanto, embora a relação proteína C-reativa/albumina tenha sido menor nos pacientes com perda auditiva neurossensorial súbita que responderam ao tratamento em comparação a aqueles que não apresentaram resposta, a diferença entre os dois grupos não foi estatisticamente significante.

ABSTRACT

Introdução: Pacientes portadores de vasculopatia periférica internam recorrentemente para procedimentos cirúrgicos ou tratamento clínico devido a complicações da doença de base. O real impacto da desnutrição nesses pacientes durante a internação ainda é pouco compreendido. Objetivo: Investigar os fatores de risco associados à mortalidade em pacientes internados com doença vascular periférica devido a complicação da doença vascular. Métodos: Estudo observacional retrospectivo avaliou cento e dezessete pacientes acima de 18 anos admitidos no serviço de cirurgia vascular de hospital terciário no período de junho de 2013 a agosto de 2014 por complicação da doença vascular. Avaliados parâmetros clínicos, comorbidades, dados demográficos, complicações durante a internação e estado nutricional. Dados coletados por meio de entrevista, aplicação do questionário Avaliação Global Subjetiva (AGS), exame físico e laboratoriais e dados de prontuário. Resultados: Cento e dezessete pacientes com doença vascular periférica avaliados em relação a complicações vasculares durante internação. Mortalidade geral de 7,7% e pacientes desnutridos ou com suspeita de desnutrição eram 39% da amostra Através da análise multivariada, tanto a classificação AGS (OR 6,15 CI 1,092-34,74 P = 0,039) quanto a presença de doença cardíaca (OR 8,51 CI 1,56-47,44 P = 0,015) foram fatores preditores independentes para mortalidade. Pacientes com doença vascular classificados em suspeita de estarem desnutridos ou desnutridos apresentaram chance de ir a óbito durante a internação aumentada em 6,15 vezes, enquanto a cardiopatia elevou essa chance 8,51 vezes. Conclusão: Pacientes internados por complicação de doença vascular periférica apresentam como fatores de risco para mortalidade a desnutrição e a presença de doença cardíaca.(AU)


Patients with peripheral vasculopathy are routinely hospitalized for surgical procedures or clinical treatment due to complications of the underlying disease. The real impact of malnutrition in these patients during hospitalization is still poorly understood. Aim: This study aimed to assess mortality predictors in patients with peripheral vascular disease during hospitalization. Methods: This retrospective observational study evaluate one hundred and seventeen patients over 18 years admitted to the vascular surgery service of a tertiary hospital in the period of June 2013 and August 2014 due to complications of vascular disease. They were assessed for clinical parameters, comorbidities, demographics, complications during hospitalization and nutritional status. Data were collected through interviews, the questionnaire Subjective Global Nutritional Assessment (SGA), laboratory exam and physical examination. Results: One hundred and seventeen patients with peripheral vascular disease were followed during admission due to vascular complications. Overall mortality was 7.7%, and malnourished patients or patients at nutritional risk were 39,0% of the sampled population By multivariate analysis both rating by SGA (OR 6.15, CI 1.092 to 34.74, P = 0.039), the presence of heart disease (OR 8.51 CI 1,56 to 47.44 P = 0.015) were independent predictors of mortality. When the patient was classified as malnourished or suspected of being malnourished by SGA it increased 6.15 times the odds of death during hospitalization, while the presence of heart disease increased by 8.51 times. Conclusion: Patients hospitalized for complications of peripheral vascular disease present as risk factors for mortality: malnutrition and the presence of heart disease. (AU)

ABSTRACT

RESUMEN El médico asistencial debe evaluar a diario las pruebas hepáticas en personas con afecciones del hígado, o en los llamados controles a personas supuestamente normales. El objetivo fue facilitar la reflexión práctica en la interpretación de las pruebas hepáticas. Se realizó una revisión de las publicaciones más importantes en base de datos como MEDLINE, EMBASE y Scielo en los últimos años para facilitar la interpretación de las pruebas de laboratorio en el estudio de las lesiones del hígado. En la práctica diaria la elevación de las aminotransferasas, ha sido asociada con un incremento en la mortalidad total y está relacionada con disfunción hepática. Los estudios imagenológicos al igual que la biopsia hepática pueden ser considerados cuando las pruebas hepáticas no definen el diagnóstico, para estudiar al enfermo o cuando los posibles diagnósticos sean múltiples, por lo que definir el valor de la elevación de los niveles de alanino aminotransferasas, aspartato aminotransferasas, junto a la los niveles de fosfatasa alcalina y bilirrubina en la lesión colestática, unidas al uso de pruebas que miden el metabolismo celular en la enfermedad hepatocelular o la colestasis son de vital importancia la práctica médica diaria (AU).


SUMMARY The physician providing health care should daily evaluate hepatic testes in persons with liver diseases, or in the so-called controls to persons supposedly healthy. The aim of this work was facilitating practical reflection in the interpretation of hepatic testes. The most important works published in MEDLINE, EMBASE and Scielo during the last years were reviewed for understanding laboratory tests in the study of hepatic lesions. In the regular practice the increase of aminotransferases has been associated to a growth of total mortality, and this one related to hepatic dysfunction. The imaging studies and also hepatic biopsy should be taking into consideration when hepatic testes do not define the diagnosis, to study the patient, or when there are many possible diagnoses; therefore defining the growth of the alaninotransferase and aspartate aminotransferase levels together with the levels of alkaline phosphatase and bilirubin in the cholestasis lesion and the use of testes measuring the cell metabolism in the hepatocellular disease or cholestasis are very important in the day-to-day medical practice (AU).

ABSTRACT

Abstract Objective: To investigate the effect of continuous lung ventilation with low tidal volume on oxidation parameters, such as thiol/disulphide homeostasis and albumin-adjusted ischemia-modified albumin (AAIMA), during cardiopulmonary bypass (CBP) in coronary artery bypass grafting (CABG). Methods: Seventy-four patients who underwent elective CABG with CPB were included in the study. Blood samples were taken in the preoperative period, 10 minutes after CPB, and six and 24 hours postoperatively. Patients were assigned to the continuous ventilation group (Group 1, n=37) and the non-ventilated group (Group 2, n=37). The clinical characteristics, thiol/disulphide homeostasis, ischemia-modified albumin (IMA), and AAIMA levels of the patients were compared. Results: A significant difference was found between the groups regarding native thiol, total thiol, and IMA levels at the postoperative 24th hour (P=0.030, P=0.031, and P=0.004, respectively). There was no difference between the groups in terms of AAIMA. AAIMA levels returned to preoperative levels in Groups 1 and 2, at the 6th and 24th postoperative hours, respectively. Length of hospital stay was significantly shorter in Group 1 (P<0.001) than in Group 2. Conclusion: Continuous ventilation during CPB caused an increase in native and total thiol levels, an earlier return of AAIMA levels, and shorter hospital stay. Continuous ventilation may reduce the negative effects of CPB on myocardium (Table 2, Figure 1, and Reference 31).

ABSTRACT

ABSTRACT Objectives: To investigate whether Glasgow Prognostic Score has prognostic significance in patients with upper urinary urothelial carcinoma. Patients and methods: We retrospectively reviewed the clinical records of 74 patients with upper urinary urothelial carcinoma. We set the cut-off value for C-reactive protein as 1.0mg/dL, and 3.5mg/dL for albumin as Glasgow Prognostic Score. Their blood data including albumin and C-reactive protein for Glasgow Prognostic Score and cytokeratin 19 fragment 21-1 as a tumor marker were measured before starting treatment. The patients were stratified into three groups with Glasgow Prognostic Score: The Group-1, albumin ≥3.5g/dL and C-reactive protein < 1.0mg/dL; Group-2, albumin < 3.5g/dL or C-reactive protein ≥1.0mg/dL; Group-3, albumin < 3.5g/dL and C-reactive protein ≥1.0mg/dL. Results: The median follow-up for all patients was 26.9 months (range: 10.9-91.1 months), during which 37 (50%) patients died. There was a significant difference in the estimated survival rate among the 3 groups stratified by Glasgow Prognostic Score. The estimated survival rate in the Group-1 was significantly higher than those in Groups 2 and 3. In the univariate analysis C-reactive protein, serum cytokeratin 19 fragment 21-1 and Glasgow Prognostic Score were significant predictors of overall survival. On the multivariate analysis, serum cytokeratin 19 fragment 21-1 and Glasgow Prognostic Score were independently associated with shorter overall survival. Conclusion: Our review suggests Glasgow Prognostic Score may play as a prognostic predictor for upper urinary urothelial carcinoma.

ABSTRACT

Abstract BACKGROUND: Tacrolimus, for its activity on modulation of collagen production and fibroblast activity, may have a role in the prevention of hypertrophic scars. OBJECTIVES: Evaluate macroscopic, microscopic, metabolic, laboratory effects and side effects of the use of topical tacrolimus ointment, in different concentrations, in the prevention of hypertrophic scars. METHODS: Twenty-two rabbits were submitted to the excision of 2 fragments of 1 cm of each ear, 4 cm apart, down to cartilage. The left ear of the animals was standardized as control and Vaseline applied twice a day. The right ear received tacrolimus ointment, at concentrations of 0.1% on the upper wound and 0.03% on the lower wound, also applied twice a day. Macroscopic, microscopic, laboratory criteria and the animals' weight were evaluated after 30 days of the experiment. RESULTS: Wounds treated with tacrolimus, at concentrations of 0.1% and 0.03%, when compared to control, showed a lower average degree of thickening (p = 0.048 and p <0.001, respectively). The average of scar thickness and lymphocyte, neutrophil and eosinophil concentrations are lower in the treated wounds compared to the control (p <0.001, p=0.022, p=0.007, p=0.044, respectively). The mean concentration of lymphocytes is lower in wounds treated with a higher concentration of the drug (p=0.01). STUDY LIMITATIONS: experiment lasted only 30 days. CONCLUSIONS: Tacrolimus at the 2 concentrations evaluated reduced the severity of inflammatory changes and positively altered the macroscopic aspect of the scar in the short term. Its use was shown to be safe, with no evidence of systemic or local adverse effects.

ABSTRACT

Resumo A desnutrição é um fator relevante na evolução dos pacientes com doença renal crônica (DRC) em hemodiálise (HD), estando associada a maior frequência e duração de internações hospitalares. Objetivou-se avaliar o estado nutricional de pacientes com DRC em HD em unidades públicas ou privadas vinculadas ao SUS no Distrito Federal. Dados sociodemográficos, bioquímicos e antropométricos foram obtidos de 96 participantes, sendo 35,5% provenientes de hospitais públicos. Os critérios utilizados para avaliação de desnutrição na DRC foram Índice de Massa Corpórea (IMC) < 23 kg/m2, circunferência muscular do braço (CMB) reduzida e albumina sérica < 3,8 g/dl. Do total de avaliados, 14,6% apresentou desnutrição (60 ± 12 anos; 57% masculino; 69% clínicas privadas); 33,3% apresentou estado nutricional adequado (55 ± 14 anos; 53% masculino; 57% clínicas privadas); 52,1% tinha ao menos uma variável relacionada à desnutrição, onde o IMC abaixo do recomendado foi o mais prevalente (42,7%), seguido da CMB reduzida (41,7%) e da albumina sérica (33,3%). Com base nos resultados conclui-se que ao menos uma variável relacionada ao estado nutricional esteve alterada em metade da amostra estudada, o que reforça a importância da avaliação nutricional no contexto do tratamento da DRC.


Abstract Malnutrition is a major factor in the evolution of patients with chronic kidney disease (CKD) on hemodialysis (HD). It is associated with increased frequency and the duration of hospitalizations. The scope of this study was to evaluate the nutritional status of patients with CKD on HD in public or private clinics of the Unified Health System in the Federal District. Sociodemographic, biochemical and anthropometric data were obtained from 96 participants, 35.5% of which were from public clinics. Parameters for evaluation of malnutrition in CKD included Body Mass Index (BMI) < 23 kg/m2, reduced arm muscle circumference (AMC) and serum albumin < 3.8 g/dL. From all participants, 14.6% were classified as malnourished (60 ± 12 years; 57% male; 69% private clinics); 33.3% presented adequate nutritional status (55 ± 14 years; 53% male; 57% private clinics); 52.1% had at least one parameter related to malnutrition. BMI below the recommended parameter was the most prevalent variable (42.7%), followed by reduced AMC (41.7%) and serum albumin (33.3%). Based on these results, it may be concluded that at least one positive variable was related to malnutrition in half of the sample, which reinforces the importance of nutritional assessment in the context of the treatment of CKD.

ABSTRACT

Abstract Purpose: To establish a new rat model, the pathogenesis of which is closer to the clinical occurrence of chronic obstructive jaundice with liver fibrosis. Methods: 90 SD rats were randomly divided into 3 groups. Group A common bile duct ligation, group B common bile duct injection compont and group C injection saline. The serum of three groups was extracted, and the liver function was detected by ELISA. HE staining, Masson staining and immunohistochemistry were used to detect liver pathology. Results: Group B showed a fluctuant development of jaundice, obstructive degree reached a peak at 2 weeks, and decreased from 3 weeks. HA, LA and PCIII were significantly higher than control group. 3 weeks after surgery, liver tissue fibrosis occurred in group B, and a wide range of fiber spacing was formed at 5 weeks. Immunohistochemistry showed that hepatic stellate cells were more active than the control group. Conclusion: Intra-biliary injection of Compont gel is different from the classic obstructive jaundice animal model caused by classic bile duct ligation, which can provide an ideal rat model of chronic obstructive jaundice with liver fibrosis.

INTRODUCTION: Malnutrition, being a condition with a multifactorial etiology, is very frequent in dialysis patients. OBJECTIVE: TO make a diagnosis of the situation and the evolution of parameters following nutrition intervention. Expected goals after six months: nutritional assessment of 100% of patients; 70% with type A subjective global assessment (SGA); 80% with ≥3.5 g/dL albumin levels, and 70% with >0.8 g/kg/day protein intake (nPNA). METHODS: Patients undergoing dialysis for more than 90 days were evaluated during March and April (diagnostic stage) and November and December 2016 (evolution of parameters), recording personal, anthropometric and laboratory data, food history and SGA. The nutritional actions were: interviews to patients and relatives, education through group talks and indication of hyperproteic supplements to patients selected according to appetite, weight loss and albumin. RESULTS: In the diagnostic stage, 35 patients were evaluated; 18 (51%) had BMI > 23 and < 35; 9 (26%) with nPNA > 0.8 g/kg/day. Albumin was ≥3.5 g/dL in 24 patients (69%). Type A SGA in 16 patients(46%); type B in 12 of them (34%) and type C in 7 (20%). Five patients received supplements (14%). In a later stage, 28 patients were evaluated; 11 (39%) with BMI > 23 and < 35. nPNA; > 0.8 g/kg/day in 27 patients (96%). Albumin was ≥3.5 g/dL in 23 patients (82%). Type A SGA in 18 patients (64%); type B in 9 of them (32%) and type C in 1 (4%). 100% of the supplemented subjects achieved the expected goals. CONCLUSION: Periodic nutritional assessment, interventions and supplementation improve the short-term nutritional goals of the dialysis population

ABSTRACT

Abstract Purpose: The effect of a prophylactic oleuropein-rich diet before anesthesia accompanied by the widely-used steroid-based neuromuscular drug rocuronium on mast cell activation was investigated in the study. Methods: 14 rabbits used in the study. The rabbits in the oleuropein group were given oleuropein-rich extract added to the animals' water at doses of 20 mg/kg oleuropein for 15 days orally. After 15 days, all rabbits in the two groups were given general anesthesia with rocuronium of 1 mg/kg. After 1 day, animals were sacrificed and the liver tissue sections stained with H&E, toluidine blue and tryptase for immunohistochemical study. Results: There was no statistically significant difference between ALT, AST and albumin averages of the oleuropein and control groups (p> 0.05). The tryptase average of the control group was higher than the tryptase average of the oleuropein group and this difference was statistically significant (p=0.003). The T. blue average in the oleuropein group was higher than the control group. However, there was no statistically significant difference between groups (p=0.482). Conclusions: Rocuronium adverse effects, like hypersensitivity and anaphylaxis, may limit routine use of this substance. The use of oleuropein reduced the number of inflammatory cells and prevented degranulation.

ABSTRACT

Abstract Purpose: To evaluate the hepatic changes associated with gastric ischemia. Methods: Thirty male rabbits were studied, distributed in 3 groups (n=10). Group 1: ligature and section of the gastric vasculature and removal of the liver after three hours; Group 2: ligature and section of the gastric vasculature and removal of the liver after 6 hours; Group 3: ligature and section of the gastric vasculature and removal of the liver after 12 hours. Blood samples were collected immediately before surgery and after the determined time of ischemia in each group to evaluate the hepatic function. After the death of the rabbits, the liver was removed for macro and microscopic study. Results: An increase in aminotransferases and bilirubin occurred in groups 2 and 3. Total protein and albumin diminished in all of the animals. All of the rabbits from groups 2 and 3 presented hepatocellular necrosis. Conclusion: The devascularization of the stomach for a period of above three hours is associated with hepatic morphological and functional disorders.

ABSTRACT

ABSTRACT Purpose: To investigate the prognostic role of preoperative albumin/globulin ratio (AGR) in predicting disease-free survival (DFS) and overall survival (OS) in localized and locally advanced clear cell renal cell carcinoma (RCC) patients. Patients and Methods: 162 patients who met the criteria specified were included in the study. The DFS and OS ratios were determined using the Kaplan-Meier method. Univariate and multivariate Cox regression analyses were performed to determine the prognostic factors affecting DFS and OS. Results: Median follow-up period was 27.5 (6-89) months. There was a statistically significant relationship between low AGR and high pathological tumor (pT) stage, presence of collecting system invasion, presence of tumor necrosis, and a high platelet count (p = 0.012, p = 0.01, p = 0.001, and p = 0.004, respectively). According to the Kaplan-Meier survival analysis, both OS and DFS were found to be significantly lower in the low AGR group (p = 0.006 and p = 0.012). In the multivariate Cox regression analysis, collecting system invasion and tumor necrosis were found to be independent prognostic factors in predicting OS and pT stage was found to be an independent prognostic factor in predicting DFS (HR: 4.08, p = 0.043; HR: 8.64, p = 0.003 and HR: 7.78, p = 0.041, respectively). Conclusion: In our study, low AGR was found to be associated with increased mortality and disease recurrence in localized and locally advanced RCC.

ABSTRACT

SUMMARY INTRODUCTION Malnutrition-Inflammation-Atherosclerosis Syndrome is very frequent in patients with chronic kidney disease on haemodialysis. In these patients, the inflammation associated with malnutrition is observed by the Malnutrition-Inflammation Score. OBJECTIVE To analyse the relationship between malnutrition-inflammation-atherosclerosis syndrome and anthropometric and biochemical parameters of patients on haemodialysis. METHODS A cross - sectional study was performed at the Haemodialysis Clinic of the Barão de Lucena Hospital, Recife, Brazil, between July and August 2016, with patients cared at the clinic for at least six months. Patients with amputees, hospitalized, visually impaired, HIV positive, with catheters in the neck, ascites and/or oedema, and those who were unable to provide information at the time of the interview were excluded. The patients were submitted to anthropometric evaluation for the classification of the nutritional status by waist circumference, neck circumference, body mass index, waist-to-hip ratio and waist-to-height ratio. Nutritional status related to inflammation was measured by the Malnutrition-Inflammation Score and nutritional status assessment using biochemical indicators that used urea, creatinine and albumin. RESULTS Twenty-seven individuals of both genders, adults and elderly, aged 51.3 ± 13.3 years old participated in the study. The anthropometric evaluation showed that most of the population presented cardiovascular risk. The biochemical evaluation reported low frequencies of malnutrition. Malnutrition-Inflammation-Atherosclerosis syndrome was evidenced in 3.7% of the patients. The Malnutrition-Inflammation Score had a moderate negative correlation with body mass index, waist circumference, neck circumference, waist-to-height ratio and creatinine. CONCLUSION The correlation seen among the parameters suggests that most of the parameters evaluated can be used as an indirect indicator of malnutrition-inflammation-atherosclerosis syndrome.


RESUMO INTRODUÇÃO A síndrome Desnutrição-Inflamação-Aterosclerose é frequente nos pacientes com doença renal crônica em hemodiálise, acarretando perda de proteínas corporais e produção de citocinas pró-inflamatórias. OBJETIVO Verificar, entre os indicadores nutricionais estudados, aqueles que melhor se correlacionam com a síndrome Desnutrição-Inflamação-Aterosclerose em pacientes submetidos à hemodiálise. MÉTODOS O estudo foi transversal, realizado na Clínica de Hemodiálise do Hospital Barão de Lucena, no Recife (PE), entre julho e agosto de 2016, com pacientes atendidos há pelo menos seis meses. Foram excluídos pacientes amputados, internados, com deficiência visual, cateter no pescoço, HIV positivo, ascite e/ou edema e aqueles incapazes de prestar informações no momento da entrevista. Os pacientes foram submetidos à avaliação antropométrica para a classificação do estado nutricional pela circunferência da cintura, perímetro do pescoço, índice de massa corporal, relação cintura-quadril e relação cintura-estatura. O estado nutricional relacionado à inflamação foi mensurado pelo escore Desnutrição-Inflamação e a avaliação do estado nutricional pelos indicadores bioquímicos: ureia, creatinina e albumina. RESULTADOS Participaram do estudo 27 indivíduos de ambos os sexos, adultos e idosos, com idade de 51,3 ± 13,3 anos. A avaliação antropométrica mostrou que a maior parte da população apresentava risco cardiovascular. A avaliação bioquímica relatou baixas frequências de desnutrição. Foi evidenciada síndrome Desnutrição-Inflamação-Aterosclerose em 3,7% dos pacientes. O escore Desnutrição-Inflamação apresentou correlação moderada negativa com o índice de massa corporal, circunferência da cintura, perímetro do pescoço, relação cintura-estatura e creatinina. CONCLUSÃO A correlação observada entre os parâmetros sugere que a maioria dos parâmetros avaliados pode ser utilizada como indicador indireto da síndrome Desnutrição-Inflamação-Aterosclerose.

ABSTRACT

Abstract: Background: Rheumatoid arthritis is a chronic inflammatory disease characterized by polyarthritis with progressive articular wear, immunologic abnormalities and increasing physical limitation. Surgical correction with hip replacement comes as a successful solution for patients with advanced articular destruction. Following intervention, surgical site infection (SSI), venous thromboembolism, sepsis, renal and major cardiovascular complications are among the most cited in the literature. No consensus exists as to the detection of preoperative hypoalbuminemia in patients with rheumatoid arthritis. Methods: This study retrospectively evaluated the preoperative serum albumin of 75 patients with rheumatoid arthritis and analyzed its relevance in terms of appearance of postoperative complications with a six-month follow-up. Complications in the group of patients with low serum albumin and the group of patients with normal serum albumin were reviewed to identify the effect of each variable. Odds ratio for each variable was calculated (hospital readmission, surgical site infection, renal and cardiac complications, non-infectious wound complications and the presence of residual hip pain), as well as p-value and confidence intervals. Results: Surgical site infection showed a statistically significant relation with low serum albumin (OR: 6.125, p = 0.018) as did non-infectious wound complications (OR: 3.714, p = 0.026) and residual hip pain (OR: 3.149, p = 0.022). Conclusion: Preoperative low serum albumin has a direct relation with the rate of postoperative complications including SSI, non-infectious wound complications (seroma formation, wound dehiscence) and residual hip pain. Preoperative serum albumin is a reliable marker of nutrition, which may establish preventive strategies to reduce postoperative complications in patients with rheumatoid arthritis.


Resumen: Introducción: La artritis reumatoide es una enfermedad inflamatoria crónica con desgaste articular progresivo, anomalías inmunológicas y aumento de la limitación física. La corrección quirúrgica con el reemplazo de la cadera es una solución a la destrucción articular avanzada. Después de la intervención, la infección del sitio quirúrgico (SSI), el tromboembolismo venoso, la sepsis y las complicaciones cardiovasculares o renales se encuentran entre las más citadas en la literatura. No existe consenso en cuanto a la detección de hipoalbuminemia preoperatoria en pacientes con artritis reumatoide. Métodos: Estudio retrospectivo evaluando la albúmina de suero preoperatoria de 75 pacientes con artritis reumatoide, se analizó su importancia en términos de complicaciones postoperatorias en los primeros seis meses de seguimiento. Las complicaciones en el grupo de pacientes con albúmina de suero baja y el grupo de pacientes con albúmina de suero normal fueron repasadas para identificar el efecto de cada variable. Se calculó el odds ratio para cada variable (reingreso hospitalario, infección del sitio quirúrgico, complicaciones renales y cardíacas, complicaciones no infecciosas de la herida y presencia de dolor de cadera residual), así como el valor p y los intervalos de confianza. Resultados: La infección del sitio quirúrgico demostró una relación estadística significativa con la albúmina de suero baja (o: 6.125, p = 0.018) al igual que complicaciones no infecciosas de la herida (o: 3.714, p = 0.026) y dolor residual de la cadera (o: 3.149, p = 0.022). Conclusión: La albúmina sérica baja preoperatoria tiene una relación directa con la tasa de complicaciones postoperatorias: infección, formación de seromas, dehiscencia de la herida y dolor residual.

ABSTRACT

ABSTRACT BACKGROUND: Acute kidney injury (AKI) is a common complication in the immediate postoperative period of patients undergoing liver transplantation. OBJECTIVE: The aim of this study was to evaluate preoperative risk factors for AKI after liver transplantation. METHODS: A cross-sectional study was conducted with adults submitted to orthotopic liver transplantation at a reference hospital in Fortaleza, Northeast of Brazil, from January to December 2016. Preoperative risk factors were evaluated for AKI development in the immediate postoperative period. AKI was defined according to the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. RESULTS: A total of 40 patients were included in the study. AKI was found in 85% of patients in the first 24 hours after transplantation, most of them (40%) classified in KDIGO stage 1. Preoperative data indicate that serum albumin levels were lower in the KDIGO stage 3 group compared to the non-AKI group, as well as the hematocrit levels. Direct bilirubin (DB) was higher in the KDIGO stage 3 group compared to the group without AKI, as well as alkaline phosphatase (AP) and gamma-glutamiltransferase (GGT). In a logistic regression analysis independent risk factors for AKI were increase levels of AP, GGT and DB and decrease level of serum albumin. CONCLUSION: Low levels of serum albumin, and elevated levels of DB, AP and GGT in the preoperative period are risk factors for AKI development after liver transplantation.


RESUMO CONTEXTO: Lesão renal aguda (LRA) é uma complicação comum no pós-operatório imediato do transplante hepático. OBJETIVO: O objetivo foi avaliar os fatores de risco pré-operatórios para LRA após o transplante hepático. MÉTODOS: Foi realizado estudo transversal com adultos submetidos a transplante hepático ortotópico em um hospital de referência em Fortaleza, Nordeste do Brasil, de janeiro a dezembro de 2016. Foram avaliados os fatores de risco pré-operatórios para o desenvolvimento de LRA no pós-operatório. LRA foi definida de acordo com os critérios do Kidney Disease: Improving Global Outcomes (KDIGO). RESULTADOS: Foram incluídos 40 pacientes no estudo. LRA foi encontrada em 85% dos casos nas primeiras 24 horas após o transplante, sendo a maioria deles (40%) classificados no estágio KDIGO 1. Os dados pré-operatórios indicaram que os níveis séricos de albumina eram menores nos pacientes no estágio KDIGO 3, em comparação com o grupo sem LRA, bem como os níveis de hematócrito. Os níveis de bilirrubina direta (BD) eram maiores nos pacientes no estágio KDIGO 3 em comparação ao grupo sem LRA, bem como os níveis de fosfatase alcalina (FA) e gama-glutamiltransferase (GGT). Em um modelo de regressão logística, os fatores de risco independentes para LRA foram: níveis elevados de FA, GGT e BD e níveis reduzidos de albumina. CONCLUSÃO: Níveis reduzidos de albumina sérica, e níveis elevados de BD, FA e GGT no período pré-operatório são fatores de risco para o desenvolvimento de LRA após o transplante hepático.

ABSTRACT

Summary Objective: To analyze the nutritional status of selenium and verify the effect of its supplementation in pediatric patients during 14 days of parenteral nutrition (PN). Method: This is a series of cases with patients followed for two weeks while using PN. Data collection was performed at the beginning (T0), in the 7th (T1) and 14th days of PN (T2). The supplemented group received 2 µg/kg/day of selenous acid. Weight and height were measured for nutritional status assessment. Tests requested: plasma selenium, albumin, pre-albumin, C-reactive protein (CRP), total cholesterol and HDL-cholesterol. Results: Fourteen (14) patients with inflammatory process and with low or very low weight for their ages were evaluated. In both groups (with and without supplementation), all patients had low selenium levels. Median plasma selenium concentrations were 17.4 µg/L (T0), 23.0 µg/L (T1) and 20.7 µg/L (T2). Increase and reduction of selenium occurred both in patients with high CRP and in those presenting normalization of this parameter. Conclusion: Lower plasma selenium levels have been detected since the start of the research and supplementation (2 µg/kg/day of selenous acid) was not to enough to approach the reference values.


Resumo Objetivo: Analisar o estado nutricional relativo ao selênio e verificar o efeito da suplementação desse mineral em pacientes pediátricos durante 14 dias de nutrição parenteral (NP). Método: Trata-se de estudo prospectivo de uma série de casos de pacientes acompanhados durante duas semanas de uso de NP. A coleta de dados foi realizada no início (T0), no 7º (T1) e no 14º dia de NP (T2). Após randomização, o grupo suplementado recebeu 2 µg/kg/dia de ácido selenioso. Peso e altura foram aferidos para avaliação do estado nutricional. Exames coletados: selênio plasmático, albumina, pré-albumina, proteína C-reativa (PCR), colesterol total e HDL-colesterol. Resultados: Foram avaliados 14 pacientes com processo inflamatório em curso e com baixo ou muito baixo peso para a idade. Os pacientes (grupo suplementado e não suplementado) tinham baixas concentrações de selênio. A mediana dos valores de selênio plasmático foi de 17,4 µg/L (T0), 23,0 µg/L (T1) e 20,7 µg/L (T2). Aumento e redução de selênio ocorreram tanto nos pacientes com PCR elevada quanto naqueles que apresentaram normalização desse parâmetro. Conclusão: Os níveis de selênio detectados foram muito baixos e a suplementação (2 µg/kg/dia de ácido selenioso) não foi suficiente para normalização dos níveis plasmáticos.

ABSTRACT

ABSTRACT BACKGROUND: Chronic lung infections, inflammation and depletion of nutritional status are considered to be prognostic indicators of morbidity in patients with cystic fibrosis. The aim of this study was to investigate the association between inflammatory markers and lung function, nutritional status and morbidity among children/adolescents with cystic fibrosis. DESIGN AND SETTINGS: Prospective three-year longitudinal study conducted in an outpatient clinic in southern Brazil. METHODS: Children/adolescents aged 1-15 years with cystic fibrosis were enrolled. Nutritional status was determined from weight-to-length and body mass index-to-age z-scores and was classified as acceptable, at risk or nutritional failure. Tumor necrosis factor-α, interleukin-1β, myeloperoxidase, C-reactive protein and C-reactive protein/albumin ratio were analyzed. Lung function was evaluated based on the forced expiratory volume in the first second and morbidity according to the number of hospitalizations for pulmonary exacerbation and infections by Pseudomonas aeruginosa. Lung function, nutritional status and morbidity were the outcomes. Odds ratios and 95% confidence intervals were to evaluate the effect of baseline inflammatory markers on the clinical outcomes after three years of follow-up and p-values < 0.05 were considered significant. RESULTS: We evaluated 38 children/adolescents with cystic fibrosis: 55% female; median age (with interquartile range), 3.75 years (2.71-7.00). Children/adolescents with high C-reactive protein/albumin ratio at baseline had odds of 18 (P = 0.018) of presenting forced expiratory volume in the first second ≤ 70% after three years. The other inflammatory markers were not associated with the outcomes. CONCLUSION: C-reactive protein/albumin ratio was associated with forced expiratory volume in the first second ≤ 70% after three years.

ABSTRACT

Abstract Objectives To analyze the association between periodontal conditions and inflammation, nutritional status and calcium-phosphate metabolism disorders in hemodialysis (HD) patients. Material and Methods We analyzed 128 HD patients divided into two groups: dentate (n = 103) and edentulous (n=25). The following items were assessed: baseline characteristics, age at the start and duration of HD, biochemical data: C-reactive protein (CRP), serum albumin, calcium, phosphorus, alkaline phosphatase, parathormone. A single dentist performed a complete dental/periodontal examination, including parameters of oral hygiene and gingival bleeding. Results One person had healthy periodontium, 62.14% of the patients had gingivitis, and 36.9% had moderate or severe periodontitis. The age at HD onset had a positive impact on periodontal status and negatively correlated with the number of teeth. A positive correlation between age and CRP level and negative correlations between age and serum albumin and phosphorus were found. Pocket depth (PD) was negatively correlated with serum albumin. The number of teeth was negatively correlated with serum CRP. Conclusions High prevalence and severity of periodontal disease are observed in hemodialysis patients. There is a high probability that periodontal disease may be present at the early stages of chronic kidney disease (CKD) before the hemodialysis onset.
