  • Background: Extracorporeal membrane oxygenation (ECMO) has been widely used in patients with cardiorespiratory failure. The serum albumin level is an important prognostic marker in critically ill patients. We evaluated the efficacy of using pre-ECMO serum albumin levels to predict 30-day mortality in patients with cardiogenic shock (CS) who underwent venoarterial (VA) ECMO. Methods: We reviewed the medical records of 114 adult patients who underwent VA-ECMO between March 2021 and September 2022. The patients were divided into survivors and non-survivors. Clinical data before and during ECMO were compared. Results: Patients' mean age was 67.8±13.6 years, and 36 (31.6%) were female. The proportion of survival to discharge was 48.6% (n=56). Cox regression analysis showed that the pre-ECMO albumin level independently predicted 30-day mortality (hazard ratio, 0.25; 95% confidence interval [CI], 0.11-0.59; p=0.002). The area under the receiver operating characteristic curve of albumin levels (pre-ECMO) was 0.73 (standard error [SE], 0.05; 95% CI, 0.63-0.81; p<0.001; cut-off value=3.4 g/dL). Kaplan-Meier survival analysis showed that the cumulative 30-day mortality was significantly higher in patients with a pre-ECMO albumin level ≤3.4 g/dL than in those with a level >3.4 g/dL (68.9% vs. 23.8%, p<0.001). As the adjusted amount of albumin infused increased, the possibility of 30-day mortality also increased (coefficient=0.140; SE, 0.037; p<0.001). Conclusion: Hypoalbuminemia during ECMO was associated with higher mortality, even with higher amounts of albumin replacement, in patients with CS who underwent VA-ECMO. Further studies are needed to predict the timing of albumin replacement during ECMO.

  • Objective: Purpose was to determine the effects of grazing system and floor type on concentrations of blood metabolites, activity of creatine kinase, body weight and carcass characteristics of castrated Nguni goats. Methods: Forty eight, 7 month old goats were randomly allocated to herding and tethering treatments from 0800 to 1300 hours and accommodated on slatted and earth floors daily. Blood samples were collected by jugular venipuncture every fifteenth day for metabolite analysis. Slaughter was done at a commercial abattoir following 5 months of monitoring. Results: Tethered goats had significantly higher concentrations of urea (5.19 mmol/L) (p<0.001), creatinine ($55.87{\mu}mol/L$) (p<0.05), total protein (64.60 g/L) (p<0.01), and globulin (49.79 g/L) (p<0.001), whereas herded goats had higher glucose (3.38 mmol/L) (p<0.001), albumin (15.33 g/L) (p<0.05), albumin/globulin ratio (0.34) (p<0.01), and body weight (24.87 kg) (p<0.001). Slatted floors caused higher (p<0.01) albumin at 15.37 g/L. The interaction of grazing system and floor type affected creatinine, total protein, globulin at (p<0.01) and albumen/globulin ratio at (p<0.01). The least creatinine concentration and albumin/globulin ratio was in herded and tethered goats that were accommodated on earth floors, respectively. The highest total protein and globulin concentrations were in serum of tethered goats that were accommodated on earth floors. The highest (p<0.05) dressing percentage (45.26%) was in herded goats accommodated on slatted floors. Conclusion: Herding of goats lowered globulin concentration, improved estimated feed intake, blood glucose and albumin concentrations, albumin globulin ratio, increased body weights and weight related carcass characteristics. Floor type had very little effects on metabolites where earth floors only reduced albumin concentration. Tethering and housing goats on earth floors resulted in double stress that increased chronic infections.

  • This study investigated the nutritional status of 32 CAPD patients. Their weight, height, triceps, mid arm circumference were measured and their dietary intake and the blood profiles were evaluated. They were 56.0${\pm}$11.8 years old. Their intake of energy and protein were 78% and 93% of RDA respectively. The energy from dextrose was 376.1${\pm}$83.2kcal. The men's and women's intake of protein was 84.6% and 102.1% of RDA respectively, According to the distribution of BMI, 23.5% of the men and 6.1% of the women were underweight and 5.9% of the men and 20% of the women were overweight. The serum albumin levels of the men and women were 3.30 and 3.71g/41 respectively. However, the average amount of serum ferritin, as a whole, comes within the normal range, which shows that stored iron was not decreased and that their anemia was not caused by iron deficiency. The subjects were divided into three groups according to the level of albumin, and their intakes of nutrients were compared with one another, The group with the high level of albumin showed that energy and protein intake was significantly larger and that BMI was also significantly higher than the other groups. There was a positive correlation between BMI and energy intake. Serum total protein had a positive correlation to energy intake ; hematocrit, to carbohydrate intake. BMI had a positive correlation to energy intake. A relative magnitude of factors affecting albumin level was analyzed by Stepwise multiple regression analysis. Overall results about relative influence of independent variables to dependent variable(albumin) indicated that the blood total protein(p <0.0001) was the most significantly correlated with serum albumin level in all subjects,1311owe4 by creatinine and total cholesterol.

  • 목 적 : 고농도 인알부민은 신증후군성 부종의 치료에 효과적으로 사용되어 왔으나 고혈압, 심부전등의 위험이 있고 알부민 투여에 따른 고단백 부하가 병적인 사구체 상피세포의 손상을 가중시켜 신증후군의 임상적 경과에 나쁜 영향을 끼칠 수 있는 것으로 보고되었다. 이에 저자들은 신증후군 환아에서 인알부민 투여가 신증후군의 임상 결과에 미치는 영향을 관찰하기 위하여 전향적인 연구를 시행하였다. 방 법 : 1997년 3월부터 1999년 9월까지 이화의대 부속 목동병원 소아과에 신증후군으로 입원한 환아중 신조직 검사상 미세변화형이었으나 재발하였거나 임상적으로 미세변화형에 합당하였던 환아에게 무작위로 20$\%$ 알부민 1 g/kg과 furosemide 2 mg/kg를 1-3일간 정맥 투여하였다. 이중 표준 스테로이드 치료(prednisolone 2 mg/kg 또는 calcort-한독약품 2.4 mg/kg)에 8주 내에 반응을 보이고 1년 이상 추적 관찰이 가능했던 스테로이드 반응성 신증후군 환아 26명 (알부민 투여군 13명, 대조군 13명)을 대상으로 임상경과를 비교하였다. 결 과 : 1) 완전 관해까지의 스테로이드 치료기간은 알부민 투여군에서 $13.7{\pm}6.4$일의 대조군의 $7.5{\pm}2.8$일보다 유의하게 길었다 (P<0.05). 2) 첫 재발까지의 기간은 알부민 투여군에서 $94{\pm}63.5$일로 대조군의 $190{\pm}106.4$일에 비하여 유의하게 짧았다 (P<0.05). 완전 관해후 1년내 재발율은 알부민 투여군에서 77$\%$ (10/13)로 대조군의 46$\%$(6/13)보다 높았으나 두군간에 유의한 차이는 없었다 (P>0.05). 완전 관해후 1년간 재발 횟수는 알부민 투여군이 $1.9{\pm}0.8$회로 대조군의 $1.5{\pm}0.5$회와 유의한 차이는 없었다 (P>0.05). 3) 일회뇨단백/크레아티닌 비는 알부민 투여군에서 투여 후 2, 4일에 유의하게 증가하였다 (P<0.05). 4) 일일체중감소, 혈압, 혈청 Na, K 농도의 변화에는 두 군간에 유의한 차이가 없었다 (P>0.05). 결 론 : 스테로이드 반응성 신증후군에서 인알부민 투여는 스테로이드에 대한 반응을 지연시키고 첫 재발까지의 기간을 단축시키는등 임상결과를 악화시킬 수도 있으므로 알부민 투여에 신중을 기하여야 할 것으로 생각된다.

  • High potassium cardioplegia is a widely accepted procedure to enhance myocardial protection from ischemic injuries associated with open heart surgery. Maintaining optimum osmolarity of the cardioplegic solution is one of the required conditions for an ideal cardioplegic solution Albumin is an frequently added component for maintaining optimum osmolarity of clinically used cardioplegic solutions. But the source of albumin is human blood so that the supply is limited and the cost of manufacturing is relatively high. Recently there are moves to minimized the use of blood product for fear of blood-associated infections or immunological disorders. In this experiment, we substituted mannitol or glucose for albumin added to the cardioplegic solution which has been used at the Wonju Medical College, To determine whether addition of mannitol or glucose instead of albumin in the cardioplegic solution can produce satisfactory myocardial protection during ischemia, three different groups of isolated rat heart perfused by modified Langendorff technique were studied. Wonju Cardioplegic Solution was selected as a standard high potassium[18mEq/L of K+] cardioplegic solution. Three kinds of cardioplegic solution were made by modifying the composition maintaining the same osmolarity[339$\pm$1mOsm/Kg] Isolated rat heart were perfused initially with retrograde nonworking mode and then changed to working mode. After measuring the heart rate, systolic aortic pressure, aortic flow, coronary flow, ischemic arrest by aorta cross clamp and cardioplegia was made maintaining the temperature of water jacket at 10oC. The heart was rewarmed and reperfused after 60min of ischemic arrest with intermittent cardioplegia at the 30min interval. The time to return of heart beat and the time required to get. Regular heart beat were observed after reperfusion. The recovery rate of the functional variables-heart rate, systolic aortic pressure, aortic flow, coronary flow and cardiac output were calculated and compared among the three groups of different cardioplegia-albumin, mannitol, and glucose. The wet weight and dry weight was measured and the water content of the heart as figured out for comparison. The time to return of heart beat was fastest in the albumin group, The functional recovery rates were best in the albumin group also. In the above conditions, albumin was the best additive to the cardioplegic solution compared to the mannitol or glucose.

  • Background: Several prognostic factors have been studied in NSCLC, although it is unknown which is most useful. In this study, we aimed to investigate whether pre-treatment serum albumin level has prognostic value in patients with Stage IIIB NSCLC. Materials and Methods: This cross-sectional study included a total of 204 patients with Stage IIIB NSCLC who met the inclusion criteria. Pre-treatment serum albumin levels and demographic, clinical, and histological characteristics, as well as laboratory variables were recorded. A cut-off value was defined for serum albumin level and the patients were stratified into four groups on thios basis. Results: The majority of the patients was males and smokers, with a history of weight loss, and squamous histological type of lung cancer. The mean serum albumin level was $3.2{\pm}1.7g/dL$ (range, 2.11-4.36 g/dL). A cut-off value 3.11 g/dL was set and among the patients with a lower level, 68% had adenocarcinoma and 82% were smokers. The patients with low serum albumin levels had a lower response rate to e first-line chemotherapy with a shorter progression-free survival and overall survival. Multivariate analysis showed that low serum albumin level was an independent poor prognostic factor for NSCLC. Conclusions: This study results suggest that low serum albumin level is an independent poor prognostic factor in patients with Stage IIIB NSCLC, associated with reduction in the response rate to first-line therapy and survival rates.

  • Background: Prior studies showed a relationship between serum albumin and the albumin to globulin ratio with different types of cancer. We aimed to evaluate the predictive value of the albumin-globulin ratio (AGR) for survival of patients with lung adenocarcinoma. Materials and Methods: This retrospective study included 240 lung adenocarcinoma patients. Biochemical parameters before chemotherapy were collected and survival status was obtained from the hospital registry. The AGR was calculated using the equation AGR=albumin/(total protein-albumin) and ranked from lowest to highest, the total number of patients being divided into three equal tertiles according to the AGR values. Furthermore, AGR was divided into two groups (low and high tertiles) for ROC curve analysis. Cox model analysis was used to evaluate the prognostic value of AGR and AGR tertiles. Results: The mean survival time for each tertile was: for the $1^{st}$ 9.8 months (95%CI:7.765-11.848), $2^{nd}$ 15.4 months (95%CI:12.685-18.186), and $3^{rd}$ 19.9 months (95%CI:16.495-23.455) (p<0.001). Kaplan-Meier curves showed significantly higher survival rates with the third and high tertiles of AGR in comparison with the first and low tertiles, respectively. At multivariate analysis low levels of albumin and AGR, low tertile of AGR and high performance status remained an independent predictors of mortality. Conclusions: Low AGR was a significant predictor of long-term mortality in patients with lung adenocarcinoma. Serum albumin measurement and calculation of AGR are easily accessible and cheap to use for predicting mortality in patients with lung adenocarcinoma.
