Abstract
Malnutrition is not uncommon in arthroplasty patients, and hypoalbuminemia has been shown to be predictive of postoperative complications. The authors sought to compare albumin concentration with a global assessment of physical health, the American Society of Anesthesiologists (ASA) score, to further discriminate the importance of albumin in predicting postoperative complications. A cohort of 128,412 patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) were identified from 2005 to 2015 through use of the American College of Surgeons National Surgical Quality Improvement Program database. Patients were divided based on surgery performed, albumin concentration (with <3.5 g/dL defining hypoalbuminemia), and ASA score (≤2 vs >2). Postoperative complications were evaluated through multivariable regression analyses adjusted for age, sex, body mass index, and current smoking status. The study population included 48,751 THA and 79,661 TKA patients. On multivariable analyses, both hypoalbuminemia and ASA score were significant (P<.05) predictors of complications such as death, superficial infection, pneumonia, renal insufficiency, reintubation, transfusion, readmission, and reoperation. Furthermore, hypoalbuminemia more robustly predicted deep infection for THA patients, as well as superficial infection for TKA patients. American Society of Anesthesiologists score was otherwise predictive of more postoperative complications than hypoalbuminemia within the TKA group and provided similar predictability within the THA group. Albumin is associated with complications following THA and TKA, and if used in conjunction with ASA score, albumin contributes to enhanced risk stratification. The authors recommend that a preoperative albumin concentration be obtained and efforts made to modify this risk factor prior to elective arthroplasty. [Orthopedics. 2018; 41(6):354-362.].

Abstract
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.

Abstract
BACKGROUND Valproic acid is one of the most widely prescribed drugs for the treatment of epilepsy and bipolar disorder. As only the unbound fraction of a medicinal product is pharmacologically active, in some strong protein-bound psychotropic drugs such as valproic acid and phenytoin, a rise in this fraction can lead to severe toxicity. CASE DESCRIPTION A 65-year-old male with a type 1 bipolar disorder developed a number of neurological symptoms including sluggishness, muscle weakness, difficulty in walking and disorders of micturition after his mood stabiliser was changed to valproic acid. Recognition of drug toxicity was delayed as his total plasma valproic acid levels were within the therapeutic range. Later it became apparent that the patient had toxic unbound valproic acid levels due to hypoalbuminaemia and impaired renal function. CONCLUSION Clinicians should always consider drug toxicity in patients who show neurological symptoms and use highly protein-bound psychotropic drugs, even if the total plasma concentration of the drug is in the therapeutic range.

Abstract
OBJECTIVES Hypoalbuminaemia has been proved to be a biomarker of poor prognosis in many diseases. The objective of this study was to investigate the significance of hypoalbuminaemia in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHODS Data of 117 AAV patients were analysed retrospectively. The relationship between hypoalbuminaemia and disease severity were studied. The influence of albumin on the pathogenetic role of ANCA was investigated in vitro. RESULTS Among all patients, 52 had light hypoalbuminaemia (30g/L<=albumin<35g/L) and 40 had nephrotic hypoalbuminaemia (albumin <30g/L). Patients with hypoalbuminaemia had higher inflammation levels and more severe kidney injury than patients without hypoalbuminaemia, but no significant difference of the urinary protein levels were found between patients with nephrotic and light hypoalbuminaemia. Multivariate analysis showed serum albumin correlated with age (r=-0.566, p=0.018), C-reactive protein (r=-0.521, p=0.032) and haemoglobin (r=0.512, p=0.036). Patients with nephrotic hypoalbuminaemia had higher incidence of infection, end stage renal disease and all cause mortality during treatment than patients with light hypoalbuminaemia or normal serum albumin. In vitro study indicated albumin could inhibit the binding between ANCA and neutrophils in a concentration dependent manner. Albumin also inhibited the ANCA-induced respiratory burst and neutrophil extracellular traps formation. CONCLUSIONS Serum albumin have an inhibitory effect on the binding between ANCA and its antigen. The incidence of hypoalbuminaemia in AAV with kidney involvement is high but is not caused by heavy proteinuria. Hypoalbuminaemia is correlated with the high inflammation level and poor prognosis of AAV. Therapy targeting hypoalbuminaemia might benefit patients with AAV.

Abstract
Objectives Hypoalbuminemia occurs in 25% to 76% of patients hospitalized for
acute heart failure (HF) and is associated with increased
mortality. Hypoalbuminemia may predispose patients to
intravascular volume depletion, hypotension, and acute worsening
of renal function; however, its association with treatment
outcomes during hospitalization is unknown. Methods This retrospective cohort study involved 414 adult patients
hospitalized for HF requiring intravenous diuretics. Temporal
changes in serum albumin and the association of hypoalbuminemia
with urine output, renal function changes, blood pressure, use
of intravenous vasoactive drugs, and short-term outcomes were
assessed. Results Serum albumin decreased in most patients (72%) during
hospitalization. Hypoalbuminemia was present in 29% and 50% of
patients based on the mean admission and nadir serum albumin
level, respectively. Hypoalbuminemia as assessed by the nadir
albumin level was associated with an increased risk of acute
worsening of renal function. A nadir albumin level of <3.0
g/dL remained significantly associated in the multivariate
analyses. Conclusions Serum albumin commonly decreases during hospitalization for acute
HF. Hypoalbuminemia assessed using the nadir level during
hospitalization, not the admission level, was associated with an
increased risk of acute worsening of renal function. The timing
of serum albumin measurement may influence its utility as a
biomarker.

Abstract
Chronic abdominal pain (CAP) remains a particular challenge because of its complicated causes, especially when the disorders involve the small bowel, where it is quite difficult to intubate the flexible endoscopes. This study was to investigate the small bowel diseases detected by capsule endoscopy (CE) in CAP patients to evaluate the role of CE on CAP, and analyzed the relationship among the clinical characteristics of CAP patients and the positive rates of CE findings to search for the indications of CE for CAP patients.This retrospective study included 341 patients with CAP defined as recurrent abdominal pain for no <3 months. Each patient underwent CE after a negative diagnostic work-up. All CE images were reviewed by 3 gastroenterologists independently. The positive findings were defined as abnormal findings in the small bowel that might have been the causes of CAP. The final diagnosis was confirmed by CE findings, clinical features, histopathology, and a response to the treatment during the follow-up for at least 3 months after CE.The overall positive rate of CE findings was 28.15% (96/341). The positive rate in CAP-A (CAP with associated symptoms) group was significantly higher than that in CAP-O (CAP only) group (33.16% vs 21.38%, P = .017). Multivariate logistic regression analysis revealed that weight loss (odds ratio [OR] = 2.827, 95% confidence interval (CI) = 1.938-4.926), hypoalbuminemia (OR = 6.142, 95%IC = 4.129-8.274), elevated erythrocyte sedimentation rate (ESR) (OR = 4.025, 95%IC = 3.178-6.892), or increased C-reactive protein (CRP) (OR = 7.539, 95%CI = 5.365-11.723) were significantly associated with high positive rates. On follow-up, final diagnosis was confirmed in 56 of 69 (81.16%) patients with positive CE findings. About half of these patients (46.38%, 32/69) were diagnosed as inflammatory diseases, including Crohn disease (12), tuberculosis (5), NSAID enteropathy (4), etc. Tumors were proved in 21.74% (15/69) patients, including malignant in 7 cases and benign in 8 cases. Parasitosis was found in 9 (13.04%) patients.This study suggests that CE may be helpful for CAP patients to detect the small bowel diseases, half of which were comprised of inflammatory diseases. Besides, weight loss, hypoalbuminemia, elevated ESR, or increased CRP may be regarded as the indications of CE for CAP patients.

Abstract
BACKGROUND AND OBJECTIVES Our study explored the association of histopathologic classification of ANCA-associated GN with renal survival in Chinese patients with myeloperoxidase-ANCA-associated GN. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Two hundred fifteen patients with biopsy-proven myeloperoxidase-ANCA-associated GN were included from January of 1996 to December of 2014. The biopsies included focal (n=27), mixed (n=82), crescentic (n=47), and sclerotic (n=59) classes. The long-term renal outcome and risk factors of myeloperoxidase-ANCA-associated GN for different histopathologic classes were retrospectively analyzed. RESULTS During a median follow-up time of 22 (9-51) months, 88 (40.9%) patients reached ESRD. The 5-year renal survival (overall 58.7%) was highest in the focal class (100.0%) and lowest in the sclerotic class (20.7%), with no difference between the mixed (58.9%) and crescentic (67.4%) classes. Patients in the mixed (hazard ratio, 0.34; 95% confidence interval, 0.20 to 0.57; P<0.001) and crescentic (hazard ratio, 0.31; 95% confidence interval, 0.16 to 0.59; P<0.001) classes were at lower risk for ESRD compared with patients in the sclerotic class, as were patients who received glucocorticoids plus mycophenolate mofetil (hazard ratio, 0.32; 95% confidence interval, 0.18 to 0.60; P<0.001) compared with those receiving glucocorticoids alone. In addition, patients with a serum creatinine level ≥4 mg/dl (hazard ratio, 2.93; 95% confidence interval, 1.77 to 4.85; P<0.001) or hypoalbuminemia (hazard ratio, 2.11; 95% confidence interval, 1.32 to 3.34; P=0.002) were at higher risk for ESRD. A serum creatinine level ≥4 mg/dl and a percentage of global sclerotic glomeruli ≥60% were the two independent risk factors for ESRD in the sclerotic class. CONCLUSIONS The histopathologic classification of ANCA-associated GN in combination with serum creatinine and serum albumin levels and treatment regimen is associated with renal outcome in myeloperoxidase-ANCA-associated GN. The evaluation of serum creatinine level and percentage of global sclerotic glomeruli provides additional information on the risk of renal survival in the sclerotic class of myeloperoxidase-ANCA-associated GN.

Abstract
Feline hepatic lipidosis (FHL) is a common and potentially fatal liver disorder. Although the pathophysiologic mechanisms of FHL remain elusive, there is an imbalance between the influx of fatty acids from peripheral fat stores into the liver, de novo liposynthesis, and the rate of hepatic oxidation and dispersal of hepatic TAG via excretion of very-low density lipoproteins. The diagnosis of FHL is based on anamnestic, clinical, and clinicopathologic findings, associated with diagnostic imaging of the liver, and cytology, or histological examination of liver biopsies. Fluid therapy, electrolyte correction and adequate early nutrition are essential components of the therapy for FHL.

Abstract
Hypoalbuminemia is common and associated with a variety of disease processes, including those leading to systemic inflammatory response syndrome, gastrointestinal disorders, hepatic disorders, and glomerular diseases. Some animals develop clinical signs directly caused by low serum albumin concentration. There is strong evidence that hypoalbuminemia is associated with worse outcomes; however, evidence justifying albumin supplementation is lacking. Severe adverse events are frequently reported with administration of human serum albumin and there is little evidence of benefit from other products. Most patients will not require administration of albumin-containing products. Clinicians should consider early enteral nutritional supplementation in critically ill patients.

Abstract
We sought to investigate whether hypoalbuminaemia was mainly caused by acute or chronic factors in patients with community-acquired bacteraemia. In this population-based study, we considered 1844 adult cases of community-acquired bacteraemia that occurred in Funen, Denmark between 2000 and 2008. We used a stepwise prognostic predisposition-insult-response-organ dysfunction (PIRO) logistic regression model by initially including age and comorbidity, then added bacterial species, and finally sepsis severity. The models were furthermore analysed using receiver operating characteristic (ROC) curves. Outcomes comprised mortality incidence on days 0-30 and 31-365 after the bacteraemia episode. Each step was performed with and without baseline albumin level measured on the date of bacteraemia. In 422 patients, their latest albumin measurement taken 8-30 days before the date of bacteraemia was also used in the analysis together with the baseline albumin level. For each decrease of 1g/L in plasma albumin level, the odds ratios (95% confidence intervals) of mortality in the period of 0-30 days after bacteraemia were 0.86 (0.84-0.88) in both predisposition (P) and predisposition-insult (PI) models and 0.87 (0.85-0.89) in the full PIRO-model. The AUC values were 0.78 and 0.66 for mortality in the period of 0-30 days in the model comprising only predisposition factors with and without albumin levels added as a factor, respectively. The AUC values in the full PIRO-model were 0.81 and 0.73 with and without consideration of albumin levels, respectively. A higher proportion of patients died within 30 days if there was a decrease in the albumin level between days 8 and 30 before bacteraemia and the actual bacteraemia date. A single plasma albumin measurement on the bacteraemia date was a better prognostic predictor of short-term mortality than the sepsis severity score.

Abstract
Few studies have evaluated the risk factors for in-hospital mortality in critically ill surgical patients who have undergone emergency gastrointestinal (GI) surgery. The aim of this study was to identify the risk factors associated with in-hospital mortality in critically ill surgical patients after emergency GI surgery.The medical records of 362 critically ill surgical patients who underwent emergency GI surgery, admitted to intensive care unit between January 2007 and December 2011, were reviewed retrospectively. Perioperative biochemical and clinical parameters of survivors and nonsurvivors were compared. Logistic regression multivariate analysis was performed to identify the independent risk factors of mortality.The in-hospital mortality rate was 15.2% (55 patients). Multivariate analyses revealed cancer-related perforation (odds ratio [OR] 16.671, 95% confidence interval [CI] 2.629-105.721, P = 0.003), preoperative anemia (hemoglobin <10 g/dL; OR 6.976, 95% CI 1.376-35.360, P = 0.019), and preoperative hypoalbuminemia (albumin <2.7 g/dL; OR 9.954, 95% CI 1.603-61.811, P = 0.014) were independent risk factors of in-hospital mortality after emergency GI surgery.The findings of this study suggest that in critically ill patients undergoing emergency GI surgery, cancer-related peritonitis, preoperative anemia, and preoperative hypoalbuminemia are associated with in-hospital mortality. Recognizing risk factors at an early stage could aid risk stratification and the provision of optimal perioperative care.

Abstract
OBJECTIVES: To identify risk factors for and the rate of wound complications after laryngectomy in a large, prospectively collected national dataset, and to generate a predictive model. STUDY DESIGN: We used the National Surgical Quality Improvement Program (NSQIP) registry created by the Department of Veterans Affairs (VA) to identify patients undergoing total laryngectomy from 1989 to 1999 (n = 2063). We linked these data to inpatient and outpatient VA administrative records to capture data for prior radiation. Over 20 preoperative and intraoperative risk factors were analyzed using bivariate techniques. Those significant at the P < 0.01 level were analyzed with logistic regression and conjunctive consolidation to identify independent predictors of wound complications. RESULTS: The overall wound complication rate was 10.0%. In adjusted analyses, prolonged operative time (> 10 hours, odds ratio = 2.10, 95% confidence interval: 1.32-3.36), exposure to prior radiation therapy (OR =1.63, 1.07-2.46), presence of diabetes (OR = 1.78, 1.04-3.04), preoperative hypoalbumine-mia (OR =1.90, 1.32-2.74), anemia (OR =1.59, 1.07-2.36), and thrombocytosis (OR =1.48, 1.04-2.10) were independently associated with postoperative wound complications. A prognostic model using three variables—prior radiation therapy, diabetes, and hypoalbuminemia—provided excellent risk stratification into three tiers (6.3%, 13.7%, 21.7%). CONCLUSIONS: Preoperative radiation, prolonged operative time, low albumin, and diabetes were independently associated with postoperative wound infections. These results will help to identify patients at risk for wound complications, thus allowing for heightened surveillance and preventive measures where possible.

Abstract
The survival of patients with head and neck squamous cell carcinoma (HNSCC) can be affected not only by progression of the original cancer or occurrence of a second cancer but also by noncancer health event (NCHE). In this study, we evaluated the prognostic significance of early NCHEs in HNSCC patients after definitive radiotherapy (RT) or chemoradiotherapy (CRT).The prospective study cohort comprised 190 HNSCC patients who underwent definitive RT (n = 75) or CRT (n = 115). An early NCHE was defined as an event requiring hospital readmission of the patient within 12 months after treatment. Univariate and multivariate analyses were performed to identify clinicopathologic factors associated with early NCHEs, and competing and all-cause mortalities.Thirty-three patients suffered an NCHE (17.3%) and 8 succumbed to a competing cause of mortality (4.2%). Twenty-two (11.6%) patients had an early NCHE: respiratory (22.8%), cerebrovascular (13.7%), gastrointestinal (13.7%), and others (50.0%). In multivariate analysis, hypoalbuminemia (P = 0.022, hazard ratio [HR] = 3.66, 95% confidence interval [CI] = 1.21-11.1), chemotherapy (P = 0.047, HR = 3.02, 95% CI = 1.01-8.98), and tumor recurrence (P = 0.024, HR = 2.66, 95% CI = 1.14-6.22) were independent predictors of an early NCHE. Patients with early NCHEs were at high risk of competing mortality (P < 0.001, HR = 22.6, 95% CI = 4.21-121.00) and all-cause mortality (P = 0.002, HR = 4.44, 95% CI = 1.76-11.2).Early NCHEs are a major contributor to competing and all-cause mortality in HNSCC patients receiving RT or CRT. The risk factors identified could be used to predict early NCHEs.

Abstract
Chronic kidney disease (CKD) is a worldwide public health problem. Patients with CKD have a number of disorders in the organism, and the presence of oxidative stress and systemic inflammation in these patients is the subject of numerous studies. Chronic inflammation joined with oxidative stress contributes to the development of numerous complications: accelerated atherosclerosis process and cardiovascular disease, emergence of Type 2 diabetes mellitus, development of malnutrition, anaemia, hyperparathyroidism, and so forth, affecting the prognosis and quality of life of patients with CKD. In this review we presented the potential role of the myeloperoxidase enzyme in the production of reactive/chlorinating intermediates and their role in oxidative damage to biomolecules in the body of patients with chronic kidney disease and end-stage renal disease. In addition, we discussed the role of modified lipoprotein particles under the influence of prooxidant MPO intermediates in the development of endothelial changes and cardiovascular complications in renal failure.

Abstract
CONTEXT Human studies have reported conflicting results on the association of hypoalbuminemia with osteoporosis. OBJECTIVE The aim of the study is to test the independent association between hypoalbuminemia and osteoporosis. DESIGN This is a cross-sectional observation. SETTING AND PARTICIPANTS Patients are the outpatient consecutive individuals with available clinical, laboratory, and densitometry data from 2001 to 2013 in our tertiary care academic medical center. EXPOSURE Exposure is hypoalbuminemia defined as serum albumin less than 3.5 g/dL. MAIN OUTCOME MEASURE Osteoporosis is defined as bone mineral density of 2.5 SD or less below the mean peak bone mass of young, healthy adults. RESULTS Overall, 21 121 patients were included. Mean of age was 61 years (SD 14). There were 4244 males (20.1%) and 1614 patients of African-American ethnicity (7.6%). There was a graded decrease in rate of osteoporosis from 28.0% (n = 33) at albumin of 3 g/dL or less to 9.3% (n = 1548) at albumin greater than 4 g/dL (P < .001) at the femoral neck and from 20.3% (n = 24) to 6.1% (n = 1011) at the total hip (P < .001). In a fully adjusted model, the odds of osteoporosis at albumin of 3 g/dL or less was 3.31-fold (95% confidence interval [CI] 2.08-5.28, P < .001) at the femoral neck, 2.98-fold (95% CI 1.76-5.01, P < .001) at the total hip, and 2.18-fold (95% CI 1.43-3.31, P < .001) at the lumbar spine as compared with albumin greater than 4 mg/dL. A similar independent association was identified with a longer-observed duration of hypoalbuminemia. CONCLUSION In a large population, we report an independent association of osteoporosis with lower levels of serum albumin and a longer-observed duration of hypoalbuminemia.

J Arthroplasty 2015; 30:2290-5. [PMID: 26148837 DOI: 10.1016/j.arth.2015.06.003] [Citation(s) in RCA: 73] [Impact Index Per Article: 8.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2015] [Revised: 05/12/2015] [Accepted: 06/04/2015] [Indexed: 02/01/2023] Open
Abstract
Health care reform is directing clinical practice towards improving outcomes and minimizing complications. Preoperative identification of high-risk patients and modifiable risk factors present opportunity for clinical research. A total of 49,475 total hip arthroplasty patients were identified from National Surgical Quality Improvement Program between 2006 and 2013. We compared morbidly obese patients (BMI≥40 kg/m(2)) and non-morbidly obese patients (BMI 18.5-40 kg/m(2)). We also compared patients with hypoalbuminemia (serum albumin <3.5 g/dL) against those with normal albumin. Our study demonstrates that hypoalbuminemia is a significant risk factor for mortality and major morbidity among total hip arthroplasty patients, while morbid obesity was only associated with an increased risk of superficial surgical site infection. Impressively, hypoalbuminemia patients carried a 5.94-fold risk of 30-day mortality.

Abstract
OBJECTIVE To examine the association between nutritional markers at initiation and during follow up in two different cohorts of HIV-infected adults initiating highly active antiretroviral therapy (HAART) in West Africa. METHODS The ATARAO study was a one year prospective study carried in Mali. It consisted of a sample of consecutive patients initiating HAART in one of four participating centers during that period. Data were collected at time of treatment initiation (baseline) and every 3 months thereafter. The ANRS 1290 study followed Senegalese patients recruited in similar conditions. Bivariate analyses were used to identify nutritional and immunological covariates of malnutrition at baseline. Longitudinal trajectories of body mass index, hemoglobin and albumin, and their associated factors, were evaluated using mixed linear models. RESULTS In ATARAO, 250 participants were retained for analyses; of which, 36% had a BMI < 18.5 kg/m(2), nearly 60% were anemic and 47.4% hypoalbuminemic at time of treatment initiation. At baseline, low hemoglobin, hypoalbuminemia and low CD4 levels were associated with a BMI < 18.5 kg/m(2). Similarly, low BMI, low albumin and low CD4 counts were linked to anemia; while, hypoalbuminemia was associated with low hemoglobin levels and CD4 counts. In ANRS, out of the 372 participants retained for analyses, 31% had a low BMI and almost 70% were anemic. At baseline, low BMI was associated with low hemoglobin levels and CD4 counts, while anemia was associated with low CD4 counts and female sex. While treatment contributed to early gains in BMI, hemoglobin and albumin in the first 6 months of treatment, initial improvements plateaued or subsided thereafter. Despite HAART, malnutrition persisted in both cohorts after one year, especially in those who were anemic, hypoalbuminemic or had a low BMI at baseline. CONCLUSION In ATARAO and ANRS, malnutrition was common across all indicators (BMI, hemoglobin, albumin) and persisted despite treatment. Low BMI, anemia and hypoalbuminemia were associated with attrition, and with a deficient nutritional and immunological status at baseline, as well as during treatment. In spite of therapy, malnutrition is associated with negative clinical and treatment outcomes which suggests that HAART may not be sufficient to address co-existing nutritional deficiencies.

Abstract
Hemophagocytic syndrome (HPS) is a potentially life-threatening complication of systemic inflammatory disorders. Adult-onset Still disease (AOSD) is one of the systemic autoimmune diseases associated with reactive hemophagocytic syndrome (RHS). This study aimed to evaluate the characteristic findings, predictive factors, and prognosis of RHS in patients with AOSD. We retrospectively evaluated 109 patients diagnosed with AOSD and reviewed their clinical data and laboratory findings, including the biopsy results of 21 AOSD patients with RHS. Moreover, data from 17 hemophagocytic lymphohistiocytosis (HLH) patients evaluated during the same period were compared with those from the RHS patients. Twenty-one patients (19.3%) developed RHS during the course of AOSD, and only 7 patients (6.4%) were confirmed by bone marrow, liver, or lymph node biopsy. AOSD patients with RHS showed significantly higher frequencies of splenomegaly, hepatomegaly, and lymphadenopathy than did those without RHS. Moreover, patients with RHS showed significantly higher relapse rates than those without RHS (61.9% vs 18.2%, P < 0.001). Possible triggering factors inducing hemophagocytosis were detected in 16 of 21 RHS patients (76.2%): disease flare in 12 patients (75%), infection in 3 patients (18.8%), and drug use in 1 patient (6.3%). AOSD patients with RHS showed higher frequencies of leukopenia, anemia, thrombocytopenia, hypoalbuminemia, hypofibrinogenemia, hypertriglyceridemia, hyperferritinemia, and elevated lactate dehydrogenase levels than did those without RHS. Multivariate logistic regression with forward selection procedure showed that low platelet count (<121,000/mm³), anemia, and hepatomegaly were independent predictors of RHS. Patients with definite RHS and those with probable RHS showed comparable results. Although RHS is a life-threatening complication of AOSD, long-term prognosis was observed to be similar in patients with and those without RHS. Compared to RHS patients, HLH patients had poor prognosis, such as higher death rates (52.9% vs 9.5%, P = 0.005). RHS can be considered when an AOSD patient shows at least 2 of the following 3 findings: low platelet count, anemia, and hepatomegaly. Diagnostic confirmation by biopsy may not be essential if typical clinical findings of RHS are present. Moreover, prognosis of RHS was better than that of HLH diagnosed by the presence of trilineage cytopenia at admission.

Abstract
BACKGROUND Protein deficiency (PD) is a known risk factor for surgical complications; however, the risks of PD by weight class have not been well described. It was hypothesized that the combination of obesity and PD is associated with increased surgical complications compared with normal weight and normoalbuminemic patients. METHODS A total of 85,833 general surgery patients undergoing elective operations within the 2011 National Surgical Quality Improvement Program were analyzed. Patients with conditions that could potentially confound serum albumin (SA) were excluded. Patients were stratified by normal (>3.0 g/dL) versus low (<3.0 g/dL) SA. The relative impact of SA and body mass index (BMI) (as individual and as combined variables) on surgical morbidity and mortality were assessed. Multivariate analyses were performed to identify independent risk factors for morbidity and mortality. RESULTS Overall, 2,088 (2.43%) patients had low preoperative SA. 587 (28.1%) patients with low preoperative SA were obese (BMI>30), versus 39,299 (46.9%) with normal preoperative SA. Importantly, the interaction of hypoalbuminemia and BMI was independently associated with all complications among hypoalbuminemic patients with BMI>40, and mortality for patients with BMI>30 after controlling for appropriate demographic characteristics, co-morbidities, surgical wound classification, operation type, and complexity (c-statistic: .803 and .874 respectively). CONCLUSION PD and obesity appear to synergistically increase the risk of surgical complications. Paradoxically, malnutrition may be less easily recognized in obese individuals and surgeons may need to more carefully evaluate this population before surgery. Future studies should investigate therapy to correct PD specifically among obese patients before surgery.

Abstract
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.

Abstract
Hypoalbuminemia is considered an independent predictor of mortality, especially in elderly patients. It is common in patients with congestive heart failure, when is due to several mechanisms: increased volume of distribution, significant stasis in the mesenteric circulation and altered protein metabolism in the liver. These alterations are even more pregnant when tricuspid regurgitation is associated or aggravated by different risk factors (recent infections, anemia, hyperthyroidism). We present the case of an elderly patient with severe hypoproteinemia and important hypoalbuminemia associated with congestive heart failure and aggravation of tricuspid regurgitation. The differential diagnosis concluded that hypoalbuminemia was influenced by tricuspid regurgitation as it enhanced liver dysfunction and enteral protein absorption due to increased stasis in mesenteric system. On the other hand, hypoalbuminemia contributed to the progression of heart failure by favoring myocardial edema, volume overload, and diuretic resistance. This is why correct management of this situation should include removal of subclinical excess of fluid and renutrition. A multidisciplinary approach is needed in order to achieve a good control of the symptoms and a significant improvement of quality of life.

Abstract
BACKGROUND The prognostic significance of hypoalbuminemia and the dynamic changes in serum albumin during hospitalization in internal medicine wards has not been sufficiently investigated. METHODS Demographic, clinical and laboratory data were collected from 276 patients admitted to our internal medicine ward for a variety of acute disorders. Following discharge, all-cause mortality was recorded. These data were compared between patient groups, according to levels of albumin: hypoalbuminemia or normoalbuminemia (serum albumin <34 g/l and ≥ 34 g/l, respectively), on admission and discharge. RESULTS Hypoalbuminemia on admission and on discharge was found in 46% and 54% of patients, respectively. Anemia, renal dysfunction, malignant disease, hypocholesterolemia, lymphopenia and albuminuria were more prevalent in patients with hypoalbuminemia, compared to those with normoalbuminemia (p ≤ 0.03). During a median follow-up period of 23 months, 107 of 276 patients died. Mortality was significantly higher (p<0.001) in patients with hypoalbuminemia than normoalbuminemia on admission (52.0% vs. 27.5%) and on discharge (53.7% vs. 21.2%), including those admitted with normoalbuminemia and discharged with hypoalbuminemia (43.6%). Survival rate was higher for patients admitted with hypoalbuminemia and discharged with normoalbuminemia than for those remaining with hypoalbuminemia (82.4% vs. 42.8%, p=0.004). The level of albumin on discharge (each 10 g/l decrement) was the most powerful predictor of shortened survival (relative risk 2.79, 95% confidence interval 2.04-3.70). CONCLUSIONS Hypoalbuminemia on admission, as well as persistence or development of hypoalbuminemia throughout hospitalization, was associated with poor prognosis. Treatment aimed at increasing low albumin or maintaining its normal level may improve survival.

Abstract
PURPOSE OF REVIEW Diarrhea has great impact on enteral nutrition. The purpose of this review is to identify the factors leading to diarrhea during enteral nutrition and to provide the published updates on diarrhea prevention through nutritional intervention. RECENT FINDINGS Diarrhea in enteral fed patients is attributed to multiple factors, including medications (major contributor), infections, bacterial contamination, underlying disease, and enteral feeding. Diet management can alleviate diarrhea in enteral feeding. High content of fermentable oligosaccharides, disaccharides, and monosaccharides and polyols (FODMAPs) in enteral formula is postulated to induce diarrhea and lower FODMAPs formula may reduce the likelihood of diarrhea in enterally fed patients. Fiber-enriched formula can reduce the incidence of diarrhea and produce short-chain fatty acids for colonocytes. Ingesting prebiotics, nonviable probiotics or probiotic derivatives, and human lactoferrin may provide alternatives for reducing/preventing diarrhea. SUMMARY Enteral feeding is not generally considered the primary cause of diarrhea, which is frequently linked to prescribed medications. When diarrhea is apparent, healthcare members should evaluate the possible risk factors and systematically attempt to eliminate the underlying causes of diarrhea before reducing or suspending enteral feeding. Lower FODMAPs formula, prebiotics, probiotic derivatives, and lactoferrin may be used to manage enteral feeding-related diarrhea.
