C reactive protein albumin ratio as a new predictor of postoperative delirium after cholecystectomy for acute cholecystitis.

Postoperative delirium (POD) is one of the most common complications of surgery. This study aimed to identify the risk factors for POD in patients undergoing cholecystectomy for acute cholecystitis. This retrospective study included 77 patients who underwent cholecystectomy for acute cholecystitis between January 2015, and December 2020. Multiple logistic regression analysis was used to identify the factors associated with the development of delirium as the primary endpoint. Patients were divided into POD (n = 18) and non-POD (n = 59) groups and their demographic features and clinical results were compared. A significant model associated with delirium onset was predicted (Nagelkerke's R2 = 0.382), and the significantly correlated factors were C-reactive protein/albumin ratio (CAR), Subjective Global Assessment (SGA) score, and history of psychiatric disease. The predictive value of CAR for POD was evaluated using ROC analysis; the area under the curve of CAR was 0.731, with a cutoff value of 3.69. CAR, SGA score, and a history of psychiatric disease were identified as factors associated with the development of POD in patients with acute cholecystitis. In particular, the new preoperative evaluation of CAR may be beneficial as an assessment measure of the risk factor for the development of POD.

Preoperative low serum albumin increases the rate of perioperative blood transfusion in patients undergoing total joint arthroplasty: propensity score matching.

BACKGROUND: To investigate the relationship between preoperative low serum albumin and perioperative blood transfusion in patients undergoing total joint arthroplasty (TJA). METHODS: We enrolled 2,772 TJA patients from our hospital between January 1, 2017, and January 1, 2022. Clinical data were extracted from electronic medical records, including patient ID, sex, BMI (Body Mass Index), age, and diagnoses. Receiver operating characteristic curves were constructed to establish thresholds for serum albumin levels categorization. Propensity score matching (PSM) was developed with preoperative serum albumin as the dependent variable and perioperative blood transfusion-related factors as covariates, including BMI grade, age grade, sex, diagnosis, hypertension, diabetes, coronary heart disease, chronic obstructive pulmonary disease, chronic bronchitis, cerebral infarction, major surgeries within the last 12 months, renal failure, cancer, depression, corticosteroid use, smoking, drinking, and blood type. The low serum albumin group was matched with the normal albumin group at a 1:2 ratio, employing a caliper value of 0.2. Binary logistic regression was employed to analyze the outcomes. RESULTS: An under the curve of 0.601 was discovered, indicating a cutoff value of 37.3 g/L. Following PSM, 892 cases were successfully paired in the low serum (< 37.3 g/L) albumin group, and 1,401 cases were matched in the normal serum albumin (≥ 37.3 g/L) group. Binary logistic regression in TJA patients showed that the albumin OR was 0.911 with 95%CI 0.888-0.935, P < 0.001. Relative to the preoperative normal serum albumin group, TJA patients in the low serum albumin group experienced a 1.83-fold increase in perioperative blood transfusion rates (95% CI 1.50-2.23, P < 0.001). Compared to the normal serum albumin group, perioperative blood transfusion rates for TJA patients with serum albumin levels of 30-37.3 g/L, 25-30 g/L, and ≤ 25 g/L increased by 1.63 (95% CI 1.37-1.99, P < 0.001), 5.4 (95% CI 3.08-9.50, P < 0.001), and 6.43 times (95% CI 1.80-22.96, P = 0.004), respectively. CONCLUSION: In TJA patients, preoperative low serum albumin levels have been found to be associated with an increased risk of perioperative blood transfusion. Furthermore, it has been observed that the lower the preoperative serum albumin level is, the higher the risk of perioperative blood transfusion.

The risk of thromboembolic events in patients with nephrotic syndrome and relatively high albumin levels: a study over 10 years.

BACKGROUND: Low albumin level is a risk factor for thromboembolic events in patients with NS (nephrotic syndrome). However, little is known about the proportion and characteristics of patients with NS who experience thromboembolic events with relatively high albumin levels (≥ 25 g/L). Therefore, we explored the features of this specific group of patients. METHODS: This study included all hospitalized patients in our center for the past 10 years who had diagnoses of NS and relevant thromboembolic events. We divided them into 2 groups based on their serum albumin level when the thromboembolic event occurred. The clinical data were analyzed with SPSS software. RESULTS: There were 312 patients enrolled in our study. Eighty-four (26.9%) of them had relatively high albumin levels (≥ 25 g/L). Patients with NS with high albumin levels had significantly lower levels of 24-h proteinuria (P < 0.01) and a higher rate of autoimmune disease (P = 0.03) than the low-albumin group. Membranous nephropathy (MN) was the most frequent pathological type of NS in patients with thromboembolic events, regardless of their albumin level. There were significantly fewer patients with anti-PLA2R (M-type phospholipase A2 receptor)-positive MN in the high-albumin group than in the low-albumin group (P < 0.01). CONCLUSIONS: Our study found that there was still a high risk for patients with NS and relatively high albumin levels to develop thromboembolic events.

C-reactive protein/albumin ratio as a novel predictor for nutritional status of geriatric patients.

BACKGROUND AND AIMS: The C-reactive protein to albumin ratio (CAR) is a novel parameter that has been reported as a significant prognostic marker in some diseases. The purpose of the present research was to investigate the predictive value of this ratio with regard to nutritional status in geriatric patients. METHODS AND RESULTS: A total of 154 geriatric patients (age ≥65 years) who consecutively presented to the internal medicine outpatient clinic were included in this cross-sectional study. The Mini Nutritional Assessment (MNA) was used as a reference to determine the nutritional status of the patients. Based on the MNA results, the patients were divided into two groups: normal nutrition and malnourished or at risk of malnutrition. The median CAR of malnourished patients or those at risk of malnutrition was significantly higher than that of patients with normal nutritional status (p = .012). A significant negative correlation was also observed between the MNA score and the CAR (r = -0.196, p = .015). The receiver operating characteristic curve analysis indicated that the CAR was a significant predictor of malnourishment or the risk of malnutrition (p = .012). CONCLUSION: The CAR could predict which geriatric patients were malnourished or at risk of malnutrition. CAR may be used as a new tool in the nutritional screening of geriatric patients.

Glycated albumin levels are associated with adverse stroke outcomes in patients with acute ischemic stroke in China.

BACKGROUND AND AIM: Glycated albumin (GA) is a biomarker monitoring glycemia 2-4 weeks before stroke onset. This study was designed to explore the association between GA levels with poststroke outcomes in patients with acute ischemic stroke or transient ischemic attack (TIA). METHOD: Participants with ischemic stroke or TIA who had a baseline GA measurement were included in the Third China National Stroke Registry study. The effect of GA on stroke recurrence, poor functional outcomes, and combined vascular events was examined during the 1-year follow-up period. Multivariate Cox and logistic regression models were performed to evaluate the association. Discrimination tests were used to examine the incremental predictive value of GA when incorporating it into the conventional model. RESULTS: A total of 3861 participants were enrolled. At the 3-month follow-up, the elevated GA level was associated with an increased risk of poor functional outcomes (adjusted odds ratio [OR], 1.45; 95% confidence interval [CI], 1.01-2.09). A similar increase was observed for stroke recurrence (adjusted hazard ratio [HR], 1.56; 95% CI, 1.09-2.24), poor functional outcomes (adjusted OR, 1.62; 95% CI, 1.07-2.45), and combined vascular events (adjusted HR, 1.55; 95% CI, 1.09-2.20) at the 1-year follow-up. In nondiabetic patients, the association between GA and poor functional outcomes was more pronounced (adjusted OR, 1.62; 95% CI, 1.05-2.50). Adding GA into the conventional model resulted in slight improvements in predicting poor functional outcomes (net reclassification improvement [NRI]: 12.30% at 1 year). CONCLUSION: This study demonstrated that elevated GA levels in serum were associated with stroke adverse outcomes, including stroke recurrence, poor functional outcomes, and combined vascular events, in patients with ischemic stroke or TIA.

Intradialytic oral nutrition effects on malnourished hemodialysis patients: a randomized trial.

Oral nutritional supplementation (ONS) is recommended for malnourished hemodialysis patients when their nutritional intake remains inadequate to meet energy and protein requirements. Patients were randomized into two groups: the intradialytic ONS supplements (INTRA-ONS) group (N = 16) and the interdialytic ONS supplements (INTER-ONS) group (N = 16) for a duration of 12 weeks. Malnutrition inflammation score (MIS) and serum albumin levels were assessed. The total MIS decreased significantly in patients from both the INTRA-ONS group (- 6.13, 95% CI - 8.29 to - 3.96) and the INTER-ONS group (- 3.50, 95% CI - 5.56 to - 1.35). A significant difference in the change of MIS was observed between the two groups (- 3.06, 95% CI - 5.94 to - 0.17). No significant differences were observed between the groups concerning serum albumin levels, dietary intake, anthropometric measurements, or body weight. Intradialytic ONS demonstrates similar benefits on nutritional biomarkers but improves the MIS among malnourished ESRD patients compared to interdialytic ONS.Trial registration Thai Clinical Trials Registry (TCTR) identification number is TCTR20220322007: 16/09/2021.

The Role of Serum Albumin and Secretory Phospholipase A2 in Sepsis.

Sepsis is caused by a dysregulated host response to an infection that leads to cascading cell death and eventually organ failure. In this study, the role of inflammatory response serum secretory phospholipase A2 (sPLA2) and albumin in sepsis was investigated by determining the activities of the two proteins in serial serum samples collected on different days from patients with sepsis after enrollment in the permissive underfeeding versus standard enteral feeding protocols in an intensive care unit. Serum sPLA2 and albumin showed an inverse relationship with increasing sPLA2 activity and decreasing albumin membrane-binding activity in patients with evolving complications of sepsis. The activities of sPLA2 and albumin returned to normal values more rapidly in the permissive underfeeding group than in the standard enteral feeding group. The inverse sPLA2-albumin activity relationship suggests a complex interplay between these two proteins and a regulatory mechanism underlying cell membrane phospholipid homeostasis in sepsis. The decreased albumin-membrane binding activity in patients' serum was due to its fatty acid-binding sites occupied by pre-bound fatty acids that might alter albumin's structure, binding capacities, and essential functions. The sPLA2-albumin dual serum assays may be useful in determining whether nutritional intervention effectively supports the more rapid recovery of appropriate immune responses in critically ill patients with sepsis.

In Vitro Spectroscopic Investigation of Losartan and Glipizide Competitive Binding to Glycated Albumin: A Comparative Study.

Understanding the interaction between pharmaceuticals and serum proteins is crucial for optimizing therapeutic strategies, especially in patients with coexisting chronic diseases. The primary goal of this study was to assess the potential changes in binding affinity and competition between glipizide (GLP, a second-generation sulfonylurea hypoglycemic drug) and losartan (LOS, a medication commonly prescribed for hypertension, particularly for patients with concurrent diabetes) with non-glycated (HSA) and glycated (gHSAGLC, gHSAFRC) human serum albumin using multiple spectroscopic techniques (fluorescence, UV-visible absorption, and circular dichroism spectroscopy). The results indicated that FRC is a more effective glycation agent for HSA than GLC, significantly altering the albumin structure and affecting the microenvironment around critical amino acid residues, Trp-214 and Tyr. These modifications reduce the binding affinity of LOS and GLP to gHSAGLC and gHSAFRC, compared to HSA, resulting in less stable drug-protein complexes. The study revealed that LOS and GLP interact nonspecifically with the hydrophobic regions of the albumin surface in both binary (ligand-albumin) and ternary systems (ligand-albumin-ligandconst) and specifically saturate the binding sites within the protein molecule. Furthermore, the presence of an additional drug (GLP in the LOS-albumin complex or LOS in the GLP-albumin complex) complicates the interactions, likely leading to competitive binding or displacement of the initially bound drug in both non-glycated and glycated albumins. Analysis of the CD spectra suggests mutual interactions between GLP and LOS, underscoring the importance of closely monitoring patients co-administered these drugs, to ensure optimal therapeutic efficacy and safety.

Increased serum albumin corrected anion gap levels are associated with poor prognosis in septic patients with liver cirrhosis.

The prognosis of septic patients with cirrhosis is worse compared to septic patients without cirrhosis. Early and accurate prognosis determination in patients with cirrhosis and sepsis is pivotal for guiding treatment decisions. The aim of this study was to investigate the association between albumin-corrected anion gap (ACAG) and clinical prognosis of patients with sepsis and cirrhosis. This study extracted data of patients with sepsis and cirrhosis from the Medical Information Mart for Intensive Care (MIMIC-IV) database. A total of 1340 patients (64.6% male) were enrolled. After confounders adjusting, elevated ACAG had a significant association with 28-day mortality (HR1.604; 95% CI 1.258-2.048; P < 0.001). Restricted cubic spline revealed that a linear relationship between ACAG and 28-day mortality (P-nonlinear = 0.089, P-overall = 0.001). According to the ROC curve analysis, the ACAG demonstrated a higher area under the curve (AUC) of 0.703 compared to AG (0.675). Kaplan-Meier analysis revealed higher 28-day mortality in high ACAG group (log-rank test, χ^2 = 175.638, P < 0.001). Furthermore, subgroup analysis showed a significant interaction between ACAG and etiology of cirrhosis (P for interaction = 0.014). Therefore, ACAG could provide clinicians with valuable insights for guiding interventions in this high-risk population.

Red blood cell distribution width to albumin ratio associates with prevalence and long-term diabetes mellitus prognosis: an overview of NHANES 1999-2020 data.

Background: Erythrocyte dysfunction is a characteristic of diabetes mellitus (DM). However, erythrocyte-associated biomarkers do not adequately explain the high prevalence of DM. Here, we describe red blood cell distribution width to albumin ratio (RAR) as a novel inflammatory biomarker for evaluating an association with DM prevalence and prognosis of all-cause mortality. Methods: Data analyzed in this study were extracted from the National Health and Nutrition Examination Survey (NHANES) 1999-2020. A total of 40,558 participants (non-DM and DM) were enrolled in the study; RAR quartiles were calibrated at Q1 [2.02,2.82] mL/g, Q2 (2.82,3.05] mL/g, Q3 (3.05,3.38] mL/g, and Q4 (3.38,12.08] mL/g. A total of 8,482 DM patients were followed (for a median of 84 months), of whom 2,411 died and 6,071 survived. The prevalence and prognosis associated with RAR and DM were analyzed; age and sex were stratified to analyze the prevalence of RAR in DM and the sensitivity of long-term prognosis. Results: Among non-DM (n=30,404) and DM (n=10,154) volunteers, DM prevalence in RAR quartiles was 8.23%, 15.20%, 23.92%, and 36.39%. The multivariable odds ratio (OR) was significant for RAR regarding DM, at 1.68 (95% CI 1.42, 1.98). Considering Q1 as a foundation, the Q4 OR was 2.57 (95% CI 2.11, 3.13). The percentages of DM morbidity varied across RAR quartiles for dead (n=2,411) and surviving (n=6,071) DM patients. Specifically, RAR quartile mortality ratios were 20.31%, 24.24%, 22.65%, and 29.99% (P<0.0001). The multivariable hazard ratio (HR) for RAR was 1.80 (95% CI 1.57, 2.05). Considering Q1 as a foundation, the Q4 HR was 2.59 (95% CI 2.18, 3.09) after adjusting for confounding factors. Sensitivity analysis revealed the HR of male DM patients to be 2.27 (95% CI 1.95, 2.64), higher than females 1.56 (95% CI 1.31, 1.85). DM patients who were 60 years of age or younger had a higher HR of 2.08 (95% CI1.61, 2.70) as compared to those older than 60 years, who had an HR of 1.69 (95% CI 1.47, 1.94). The HR of RAR in DM patients was optimized by a restricted cubic spline (RCS) model; 3.22 was determined to be the inflection point of an inverse L-curve. DM patients with a RAR >3.22 mL/g suffered shorter survival and higher mortality as compared to those with RAR ≤3.22 mL/g. OR and HR RAR values were much higher than those of regular red blood cell distribution width. Conclusions: The predictive value of RAR is more accurate than that of RDW for projecting DM prevalence, while RAR, a DM risk factor, has long-term prognostic power for the condition. Survival time was found to be reduced as RAR increased for those aged ≤60 years among female DM patients.

Nano-anticoagulant based on carrier-free low molecular weight heparin and octadecylamine with an albumin shuttling effect.

Low-molecular-weight heparin (LMWH), derived from unfractionated heparin (UFH), has enhanced anticoagulant efficacy, long duration of action, and extended half-life. Patients receiving LMWH for preventive therapies would strongly benefit from its long-term effects, however, achieving this is challenging. Here, we design and evaluate a nanoengineered LMWH and octadecylamine conjugate (LMHO) that can act for a long time while maintaining close to 97 ± 3% of LMWH activity via end-specific conjugation of the reducing end of LMWH. LMHO can self-assemble into nanoparticles with an average size of 105 ± 1.7 nm in water without any nanocarrier and can be combined with serum albumin, resulting in a lipid-based albumin shuttling effect. Such molecules can circulate in the bloodstream for 4-5 days. We corroborate the self-assembly capability of LMHO and its interaction with albumin through molecular dynamics (MD) simulations and transmission electron microscopy (TEM) analysis. This innovative approach to carrier-free polysaccharide delivery, enhanced by nanoengineered albumin shuttling, represents a promising platform to address limitations in conventional therapies.

Exploration of the factors affecting different delirium subtypes in hospitalized COVID-19 patients: a multicentre cross-sectional study.

During the COVID-19 pandemic, delirium became a major complication that worsened patient outcomes. However, the factors influencing the severity of delirium in patients with COVID-19 have not been determined. We conducted this study to detect influencing factors associated with subtypes of delirium in patients with COVID-19. We included 1774 adult inpatients with COVID-19 from January to February 2023 at 7 sites in China. And used the 3 min Confusion Assessment Method and the Richmond Agitation-Sedation Scale for site assessment to identify and classify subtypes of delirium. Laboratory data were obtained from the Hospital Information System. After multivariate analysis, hypoactive delirium was significantly associated with age, the serum albumin concentration, frailty and sarcopenia, and health and nutritional status. Mixed delirium was significantly associated with age, D-dimer level, sarcopenia, health status and nutritional status. Additionally, hyperactive delirium was significantly associated with age, procalcitonin levels, frailty status and health status. Our findings suggest that poor nutritional status and low serum albumin concentration can help detect patients at high risk of developing hypoactive and mixed delirium. Additionally, clinical staff should pay more attention to patients with inflammatory conditions to assess and detect delirium because many influencing factors are involved in the common pathological mechanism of inflammation.

Nutrition-associated markers and outcomes among patients receiving enteral nutrition after ischemic stroke: a retrospective cohort study.

BACKGROUND: Early nutrition after acute ischemic stroke is crucial. We explored early enteral nutrition for stroke patients and evaluated changes in blood indicators as a predictor of stroke prognosis. METHODS: All hospitalized stroke patients receiving enteral nutrition were included in the study. We retrospectively collected the protein, energy, fat, and carbohydrate values for 7 days after admission. Serum albumin, total protein, and hemoglobin values were reviewed at admission and at one week. The main outcome indicators were the Modified Rankin Score, Barthel Index, and Quality of Life at 3 months. RESULTS: A total of 354 patients (mean age, 70.7 years; 59.0% male) were included. The change in serum albumin at day 7 relative to at admission was positively correlated with the Quality of Life score (p = 0.001), the Barthel Index (p = 0.004), and the modified Rankin Score (p = 0.029). The change in total protein at day 7 relative to at admission was positively correlated with the Quality of Life score (p = 0.002), the Barthel Index (p = 0.001), and the modified Rankin score (p = 0.011). The change in hemoglobin values at day 7 relative to at admission was positively correlated with the Barthel Index (p = 0.037 but not with the Quality of Life score (p = 0.237) or the modified Rankin score (p = 0.730). CONCLUSIONS: Improved nutrition-related blood indicators one week after admission were independently associated with good stroke outcomes. Nutritional support for acute ischemic stroke patients during the early hospitalization stage appears to be advisable. TRIAL REGISTRATION: This review was a retrospective cohort study. The study was retrospectively registered in the Chinese Clinical Trial Registry (No: ChiCTR2300077228). Registration date: 1/11/2023.

The Clinical Impact of Hemoglobin, Albumin, Lymphocyte, Platelet (HALP) in Gastric Cancer Patients Who Receive Curative Treatment.

BACKGROUND/AIM: We hypothesized that the hemoglobin, albumin, lymphocyte, and platelet (HALP) score may be a promising marker for the treatment and management of gastric cancer (GC). To test this hypothesis, we evaluated the clinical impact of the HALP score in patients with GC who received curative treatment. PATIENTS AND METHODS: Consecutive patients who underwent curative resection for GC at the Yokohama City University between 2005 and 2020 were selected based on their medical records. The HALP score was calculated as follows: HALP=Hemoglobin (g/l) × albumin (g/l) × lymphocytes (109/l)/platelets (109/l). RESULTS: The 3-year and 5-year overall survival (OS) rates were 88.6% and 85.8%, respectively, in patients with HALP scores of >40, and 70.3% and 57.2% in patients with HALP scores of ≤40. There were significant differences between the groups analyzed (p<0.001). In univariate analysis, age, T status, lymph node metastasis status, HALP score, lymphovascular invasion status, pathological type, and postoperative complication status were identified as significant prognostic factors for OS. In multivariate analysis, the HALP score remained a significant prognostic factor for OS [hazard ratio (HR)=2.679; 95% confidence interval (CI)=1.455-4.934, p=0.002]. Similar results were observed in the analysis of recurrence-free survival. In addition, the HALP score status affects the postoperative clinical course, including the occurrence of postoperative anastomotic leakage and the introduction of postoperative adjuvant chemotherapy. CONCLUSION: The HALP score affects both short- and long-term oncological outcomes. Thus, the HALP score may be a promising prognostic factor for the treatment and management of GC.

Serum fibrinogen/albumin ratio and early neurological deterioration in patients with recent small subcortical infarction.

BACKGROUND: Serum fibrinogen/albumin ratio (FAR) is a new inflammatory marker related to a variety of diseases, and it has been shown to be associated with stroke. This study is to investigate the relationship between serum FAR and early neurological deterioration (END) in patients with recent small subcortical infarction (RSSI). PATIENTS AND METHODS: Consecutive RSSI patients admitted to the First Affiliated Hospital of Zhengzhou University from June 2015 to June 2022 were enrolled. The National Institute of Health Stroke Scale (NIHSS) was utilized to evaluate the severity of the patients at admission and within seven days post-admission. END was defined as an increase of ≥2 points in NIHSS score from admission or ≥1 point in the motor item of the score within seven days post-admission. Multivariate logistic regression analysis was employed to identify risk factors for END. The correlation between FAR and END was investigated using restricted cubic spline (RCS) analysis. Subgroup analysis was used to assess stability across different populations. RESULTS: A total of 766 RSSI patients were included in the analysis, with 538 males (70.24%). END occurred in 115 (15.01%) patients. Multivariate logistic regression analysis revealed that FAR (OR = 1.016, 95%CI: 1.005-1.028), PAD (OR = 1.805, 95%CI: 1.161-2.807) and age (OR = 1.028, 95%CI: 1.009-1.048) were associated with END in RSSI patients. RCS analysis indicated a linear correlation between FAR and END (p for nonlinear = .128). Subgroup analysis indicated association between FAR and END in male (OR = 1.02, 95%CI: 1.00-1.03), patients aged ≤65 years (OR = 1.02, 95%CI: 1.00-1.03) and patients without smoking history (OR = 1.02, 95%CI: 1.00-1.03). CONCLUSIONS: Elevated FAR levels were associated with the occurrence of END within seven days after admission in RSSI patients, especially in men, age ≤65 years, or patients without smoking history.

Postoperative Nutritional Assessment of Laparoscopic Versus Open Partial Hepatectomy.

BACKGROUND/AIM: No studies have investigated the advantage of laparoscopic hepatectomy (LH) compared with open hepatectomy (OH) from a nutritional perspective. This study aimed to compare the postoperative nutritional status between LH and OH. PATIENTS AND METHODS: A total of 186 patients who underwent partial hepatic resection for liver tumors were analyzed retrospectively. We compared perioperative variables between LH and OH. The nutritional status was assessed using serum albumin (Alb) and rapid turnover protein concentrations. We investigated risk factors for postoperative malnutrition using univariate and multivariate analyses. RESULTS: The LH group, compared with the OH group, had a significantly shorter operative time (239 vs. 344 min, p<0.03), less intraoperative blood loss (100 vs. 343 g, p<0.01), and a shorter length of postoperative stay (8 vs. 11 days, p<0.01). Postoperative serum Alb and prealbumin concentrations in the LH group were significantly higher than those in the OH group (3.4 vs. 3.2 g/dl, p<0.01; 15.0 vs. 12.0 mg/dl, p=0.02, respectively). The multivariate analysis showed that OH (p=0.02) and hepatocellular carcinoma (p<0.01) were significant and independent risk factors for postoperative malnutrition. CONCLUSION: LH may be superior to OH in terms of the postoperative nutritional status, intraoperative blood loss, and length of postoperative stay.

Prognostic and clinicopathological significance of fibrinogen-to-albumin ratio (FAR) in patients with breast cancer: a meta-analysis.

BACKGROUND: The fibrinogen-to-albumin ratio (FAR) has been extensively studied for its role in predicting the prognosis of breast cancer (BC) patients; however, existing findings are conflicting. Therefore, this meta-analysis was conducted to identify the significance of FAR in predicting BC prognosis. METHODS: We searched PubMed, Embase, Web of Science, Cochrane Library, and China National Knowledge Infrastructure databases until May 25, 2024. The value of FAR for predicting overall survival (OS) and disease-free survival (DFS) in BC was examined by calculating the combined hazard ratios (HRs) and 95% confidence intervals (CIs). Correlations between FAR and clinicopathological factors were analyzed using combined odds ratios (ORs) and 95% CIs. RESULTS: Eight studies involving 4094 patients were included in this work. As shown by our combined data, increased FAR significantly predicted poor OS (HR = 2.84, 95% CI = 1.83-4.39, p < 0.001) and poor DFS (HR = 2.43, 95% CI = 1.66-3.58, p < 0.001) of BC. Moreover, the combined data showed that increased FAR was significantly correlated with age ≥ 50 years (OR = 2.04, 95% CI = 1.37-3.04, p < 0.001), stage III cancer (OR = 1.53, 95% CI = 1.04-2.27, p = 0.033), and the presence of lymph node metastases (OR = 1.33, 95% CI = 1.11-1.61, p = 0.002). Nonetheless, FAR was not significantly associated with tumor size, ER/PR/HER-2 status, or lymphovascular invasion in patients with BC. CONCLUSION: In this meta-analysis, higher FAR was significantly associated with unfavorable OS and DFS in patients with BC and significantly correlated with several features predictive of cancer development in BC.

A novel nomogram based on inflammatory-nutritional biomarkers for gallbladder cancer after surgical resection.

PURPOSE: Systemic inflammation and nutrition are vital for tumor progression. This study aimed to identify prognostic inflammation nutrition markers and develop a predictive nomogram for gallbladder cancer (GBC). METHODS: A total of 123 patients with GBC who underwent surgical resection at the First Affiliated Hospital of Soochow University and Suzhou Kowloon Hospital were included in our study. The final prognostic variables were identified using univariate and multivariate analyses. A nomogram model was then established, and the consistency index (C-index), calibration curves, and Kaplan-Meier analysis were performed to evaluate the accuracy and discrimination of the nomogram. The area under the receiver operating characteristic curve (AUC) and decision curve analysis (DCA) suggested that our nomogram had better predictive ability and clinical feasibility than a published model. RESULTS: The cox regression analysis showed that carcinoembryonic antigen (CEA) > 4.580, albumin-bilirubin (ALBI) > -2.091, geriatric nutritional risk index (GNRI) < 90.83, T3-T4, and N2 are independent prognostic factors. A predictive nomogram was constructed with a C-index of 0.793. In the calibration curves, the nomogram-predicted 1-, 3-, and 5-year survival matched well with the actual survival. Kaplan-Meier analysis showed that the high-risk group had worse survival than the low-risk group (P < 0.001). Finally, our nomogram achieved better 1-, 3- and 5-year AUCs than an established model (0.871, 0.844, and 0.781 vs. 0.753, 0.750, and 0.693). DCA also confirmed that our model outperformed the established model. CONCLUSIONS: In conclusion, our study revealed that CEA > 4.580, GNRI < 90.83, ALBI > -2.091, T3-T4 stage, and N2 were related to clinical outcomes of patients with GBC after surgical resection. The constructed nomogram has superior predictive ability and clinical practicality.

Metabolic responses to albumin deficiency differ distinctly between partial and full ablation of albumin expression in mice.

It had been observed that homozygous albumin knockout mice (Alb-/-) exhibit low plasma free fatty acid (FFA) concentration and improved blood glucose regulation. However, it was not yet known to what extent heterozygous albumin knockout (Alb+/-) mice would display a similar phenotype. Alb-/-, Alb+/-, and wild-type (WT) female mice were studied on a low-fat diet (LFD) or high-fat diet (HFD). On both diets, decreased plasma FFA concentration, and improved glucose tolerance test were observed in Alb-/-, but not in Alb+/-, compared to WT. Plasma adiponectin concentration showed greater elevation in Alb-/- than Alb+/-. Consistent with that, adiponectin gene expression was significantly higher in Alb-/- mice than in Alb+/- and WT mice. A dose-dependent response was observed for hepatic Acadl gene expression showing higher Acadl gene expression in Alb-/- mice than in Alb+/- and WT mice. In conclusion, although female Alb+/- mice exhibited some slight differences from WT mice (e.g., increased plasma adiponectin and hepatic Acadl gene expression), Alb+/- mice did not exhibit improved glucoregulation in comparison to WT mice, indicating that a minor suppression of albumin expression is not sufficient to improve glucoregulation. Furthermore, it is now clear that although the response of female mice to HFD might be unique from how males generally respond, still the complete albumin deficiency in Alb-/- mice and the associated FFA reduction is capable of improving glucoregulation in females on this diet. The present results have implications for the role of albumin and FFA in the regulation of metabolism.

Hypochlorous Acid-Modified Serum Albumin Causes NETosis in the Whole Blood Ex Vivo and in Isolated Neutrophils.

Type 2 diabetes mellitus (T2DM) is accompanied by halogenative stress resulting from the excessive activation of neutrophils and neutrophilic myeloperoxidase (MPO) generating highly reactive hypochlorous acid (HOCl). HOCl in blood plasma modifies serum albumin (Cl-HSA). We studied the formation of neutrophil extracellular traps (NETs) in the whole blood and by isolated neutrophils under the action of Cl-HSA. It was found that Cl-HSA induces neutrophil priming and NETosis. MPO-containing as well as MPO-free NETs were found. These NETs with different composition can be a product of NETosis of one and the same neutrophil. NET formation in neutrophils with vacuolated cytoplasm was detected. In the presence of Cl-HSA, acceleration of NET degradation was observed. Accelerated NET degradation and neutrophil priming can be the factors contributing to the development of complications in T2DM.
