RESUMO

BACKGROUND: Despite advancements in percutaneous and surgical revascularization techniques, nearly 20% of patients who undergo myocardial revascularization need repeat revascularization. Recently, identified as a prognostication factor for adverse cardiovascular events, the uric acid/albumin ratio (UAR) serves as a new marker for assessing inflammation and oxidative stress. Our objective was to investigate the association between UAR levels and repeat revascularization in young patients with acute coronary syndrome (ACS). METHODS: We enrolled 371 patients with ACS who were under the age of 55 years and who had previously undergone primary percutaneous coronary intervention. Due to their recurrent symptoms, these patients underwent subsequent coronary angiographic examination. The study cohort was splitted into two groups based on whether repeat revascularization was needed. RESULTS: The study and control groups consisted of 99 and 272 patients, respectively. The mean age of the patients in the study cohort was 41.99±4.99 years. Patients who needed repeat revascularization, in comparison to those who did not, exhibited significantly greater levels of the UAR and uric acid, along with lower levels of neutrophils, stent diameter and high density lipoprotein-cholesterol. Additionally, they had more complex disease, as described by the SYNTAX score. To identify the influential factors associated with repeat revascularization, multivariate logistic regression was performed. SYNTAX score, stent diameter, uric acid levels and the UAR were predictive of the need for repeat revascularization. CONCLUSIONS: UAR was found to be an inexpensive, easily accessible marker for identifying young patients with ACS requiring repeat revascularization.

RESUMO

BACKGROUND: Recently, the hemoglobin to albumin ratio (HAR) has been shown to be closely associated with the survival of certain malignancies. However, its prognostic value in nasopharyngeal carcinoma (NPC) remained to be elucidated. Herein, we aimed to explore the correlation between HAR and overall survival (OS) in NPC patients treated with concurrent chemoradiotherapy (CCRT). METHODS: This retrospective study included a total of 858 patients with NPC receiving CCRT between January 2010 and December 2014 in Sun Yat-sen University Cancer Center. We randomly divided them into the training cohort (N = 602) and the validation cohort (N = 206). We performed univariate and multivariate Cox regression analyses to identify variables associated with OS, based on which, a predictive nomogram was constructed and assessed. RESULTS: In both the training and validation cohorts, patients were classified into low- and high-HAR groups according to the cutoff value determined by the maximally selected rank statistics. This HAR cutoff value effectively divided patients into two distinct prognostic groups with significant differences. Multivariable Cox analysis revealed that higher T-stage, N-stage, and HAR values were significantly related to poorer prognosis in NPC patients and served as independent prognostic factors for NPC. Based on these, a predictive model was constructed and graphically presented as a nomogram, whose predictive performance is satisfactory with a C-index of 0.744 [95%CI: 0.679-0.809] and superior to traditional TNM staging system [C-index = 0.609, 95%CI: 0.448-0.770]. CONCLUSION: The HAR value was an independent predictor for NPC patients treated with CCRT, the predictive model based on HAR with superior predictive performance than traditional TNM staging system might improve individualized survival predictions.

RESUMO

BACKGROUND: Nocturia, a prevalent chronic condition, impacts individuals' quality of life but remains underexplored. This study aimed to assess the association between serum albumin levels and nocturia. METHODS: Based on the analysis of the National Health and Nutrition Examination Survey (NHANES) database (2005-2012), our study included a total of 6345 adults (≥20 years old). Nocturia was defined as ≥2 nocturnal voiding episodes. Logistic regression and smooth curve fitting analyzed the linear and nonlinear correlations between serum albumin and nocturia, with subgroup analysis. RESULTS: Among 6345 participants, 1821 (28.7%) experienced nocturia. Logistic regression analysis revealed a linear negative correlation between serum albumin and nocturia risk (OR = 0.9549, 95% CI = 0.9280 ~ 0.9827, P = 0.002). Even after quartile division of serum albumin concentration, this correlation persisted within each group, and a smooth curve fitting validated the nonlinear negative correlation between the two. Subgroup analysis further demonstrated significant impacts of body mass index (BMI), alcohol consumption, and age on this association. CONCLUSION: This cross-sectional study indicated that higher serum albumin levels were associated with a reduced risk of nocturia in U.S. adults aged 20 and older, highlighting the importance of serum albumin in the prevention and treatment of nocturia and providing clinical guidance.

RESUMO

OBJECTIVE: To investigate the relationship between the changes of C-reactive protein to Albumin Ratio (CAR) levels and Interval Debulking Surgery (IDS) outcome after Neoadjuvant Chemotherapy (NAC) in ovarian cancer patients. METHODS: A nested case-control study for 209 patients with ovarian cancer who received NAC-IDS therapy from the First Affiliated Hospital of Bengbu Medical College between 2015‒2021 was conducted. Demographic data, laboratory indicators, and imaging examinations were collected. The outcome was regarded as optimal IDS in this study. Univariate and multivariate logistic regression analyses were performed to assess the relationship of CAR before NAC, CAR after NAC and ∆CAR with optimal IDS. The authors also performed the subgroup analysis based on menopausal state. RESULTS: The end time of follow-up was January 24, 2022. A total of 156 patients had been treated with optimal IDS, and 53 with suboptimal IDS. After adjusting age, body mass index, menopausal state, NAC drug, peritoneal perfusion and CAR before NAC, the result showed that CAR after NAC (Odds Ratio [OR = 3.48], 95% Confidence Interval [95% CI 1.28‒9.48], p = 0.015) and ∆CAR (OR = 0.29, 95% CI 0.11‒0.78, p = 0.015) were associated with optimal IDS, respectively. Additionally, the authors found a significant correlation between CAR after NAC and optimal IDS (OR = 3.16, 95% CI 1.07‒9.35, p = 0.038), and ∆CAR and optimal IDS (OR = 0.32, 95% CI 0.11‒0.94, p = 0.038) among ovarian cancer patients with menopause. CONCLUSION: CAR after NAC and ∆CAR were independent prognostic markers of optimal interval debulking surgery for ovarian cancer patients.

RESUMO

Background: Carotid endarterectomy (CEA) for the prevention of upcoming vascular and cerebral events is necessary in patients with high-grade stenosis (≥70%). In the framework of the Italian National project Age.It, a pilot study was proposed aiming at the discovery of a molecular signature with predictive potential of carotid stenosis comparing 65+ asymptomatic and symptomatic inpatients. Methods: A total of 42 inpatients have been enrolled, including 26 men and 16 women, with a mean age of 74 ± 6 years. Sixteen symptomatic and 26 asymptomatic inpatients with ≥70% carotid stenosis underwent CEA, according to the recommendations of the European Society for Vascular Surgery and the Society for Vascular Surgeons. Plaque biopsies and peripheral blood samples from the same individuals were obtained. Hematobiochemical analyses were conducted on all inpatients, and plasma cytokines/molecules, such as microRNAs (miRs), IL-6, sIL-6Ralpha, sgp130, myostatin (GDF8), follistatin, activin A, CXCL9, FGF21, and fibronectin, were measured using the ELISA standard technique. MiR profiles were obtained in the discovery phase including four symptomatic and four asymptomatic inpatients (both plasma and plaque samples), testing 734 miRs. MiRs emerging from the profiling comparison were validated through RT-qPCR analysis in the total cohort. Results and conclusion: The two groups of inpatients differ in the expression levels of blood c-miRs-126-5p and -1271-5p (but not in their plaques), which are more expressed in symptomatic subjects. Three cytokines were significant between the two groups: IL-6, GDF8, and CXCL9. Using receiver operating characteristic (ROC) analysis with a machine learning-based approach, the most significant blood molecular signature encompasses albumin, C-reactive protein (CRP), the percentage of monocytes, and CXCL9, allowing for the distinction of the two groups (AUC = 0.83, 95% c.i. [0.85, 0.81], p = 0.0028). The potential of the molecular signature will be tested in a second cohort of monitored patients, allowing the application of a predictive model and the final evaluation of cost/benefit for an assessable screening test.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Diabetes mellitus is a chronic metabolic disease that affects more than 10.5% of the world's adult population. Biochemical and hematological parameters, such as albumin (ALB) and red cell distribution width (RDW), have been shown to be altered in diabetic patients. This study aimed to correlate hematological and biochemical parameters with glycated hemoglobin (HbA1c). A total of 777 adults (372 women and 405 men, aged 19-85 years) were divided into three groups: 218 participants with HbA1c < 5.7% (group A: non-diabetic), 226 with HbA1c ≥ 5.7% and <6.5% (group B: prediabetic) and 333 with HbA1c ≥ 6.5% (group C: diabetic). Biochemical and hematological parameters were compared among the three groups. An analysis of variance was performed to determine the correlations of the parameters among the groups. The ALB and sodium (Na) levels were significantly lower in group C than in groups A (ALB: 3.8 g/dL vs. 4.1 g/dL, p < 0.0001, Na: 138.4 mmol/L vs. 139.3 mmol/L, p < 0.001) and B (ALB: 3.8 g/dL vs. 4.0 g/dL, p < 0.0001, Na: 138.4 mmol/L vs. 139.6 mmol/L, p < 0.0001), whereas the RDW-standard deviation (RDW-SD) and urea were increased in group C as compared to group A (RDW: 45.8 vs. 43.9 fL, p < 0.0001, urea: 55.6 mg/dL vs. 38.5 mg/dL, p < 0.0001). The mean platelet volume (MPV) was increased in group C as compared to group A (9.3 fL vs. 9.1 fL, p < 0.05, respectively). Τhe increase in RDW-SD in group A as compared to B and C demonstrates the impact of hyperglycemia on red blood cells. Albumin and RDW might improve risk assessment for the development of diabetes. These results highlight the potential role of these parameters as an indication for prediabetes that would alert for measurement of HbA1c.

RESUMO

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.

RESUMO

OBJECTIVE: The study aimed to examine the role of the C-reactive protein to albumin ratio (CAR) as an inflammatory biomarker in relation to subclinical myocardial injury (SC-MI), addressing the limited knowledge of their association. METHODS: The study included 5,949 individuals without cardiovascular disease (CVD) from the National Health and Nutrition Examination Survey. SC-MI was identified through a Cardiac Infarction Injury Score (CIIS) of ≥ 10 units based on a 12-lead electrocardiogram. The study used multivariate logistic regression models, adjusted for potential confounders, to evaluate the relationship between CAR and SC-MI. Subgroup analyses were conducted to substantiate the results, and the non-linear correlation was assessed via restricted cubic spline (RCS) regression. RESULTS: The RCS curve showed a significant positive correlation between CAR and SC-MI (P for nonlinear = 0.2496). When adjusted for all confounders, individuals in the highest tertile of CAR exhibited a higher likelihood of SC-MI compared to those in the lowest tertile, with an odds ratio (OR) of 1.21 (95% CI: 1.06-1.39, P for trend = 0.029). A 10-unit increment in CAR was linked to a 3.6% heightened risk of SC-MI [OR = 1.036 (95% CI: 1.006, 1.066)], with this association being more prominent among male adults, non-smokers, married individuals, those without diabetes mellitus, and those with no history of cancer. CONCLUSION: The findings of this study suggest a positive correlation between CAR and SC-MI among the US adult population, indicating the potential of CAR in enhancing SC-MI prevention strategies in the general population.

RESUMO

INTRODUCTION: The aim of the study was to explore the value of serum procalcitonin to albumin (PCT/ALB) and C-reactive protein to albumin (CRP/ALB) ratios in evaluating the condition and prognosis of craniocerebral trauma (CT). MATERIAL AND METHODS: 158 patients with CT admitted to the emergency department of our hospital from January 2020 to June 2022 were selected as the study subjects. According to the Glasgow coma scale (GCS) score, 158 patients with CT were grouped in a mild group (GCS score 13-15 points, n = 68), a moderate group (GCS score 9-12 points, n = 61), and a severe group (GCS score 3-8 points, n = 29). Besides, according to the patient's Glasgow prognosis (GOS) score, 158 patients with CT were divided into a good prognosis group (GOS score 4-5 points, n = 110) and a poor prognosis group (GOS score 1-3 points, n = 48). Serum PCT/ALB and CRP/ALB levels of different groups were compared. The correlation between PCT/ALB and CRP/ALB ratios and the score of GCS and GOS was explored using Pearson correlation analysis. Prognosis-related influencing factors were found out through multivariate logistic regression. The value of serum PCT/ALB and CRP/ALB ratios in evaluating the condition and prognosis of CT was evaluated by the ROC curve. RESULTS: Patients in the moderate and severe groups had much higher ratios of PCT/ALB and CRP/ALB and sharply lower GCS scores than those in the mild group ( p < 0.001). Compared with the patients in the moderate group, those in the severe group had much higher PCT/ALB and CRP/ALB ratios and obviously lower GCS scores ( p < 0.001). Patients with poor prognosis had markedly higher PCT/ALB and CRP/ALB ratios and memorably lower GOS score than the patients with good prognosis ( p < 0.001). A negative correlation between PCT, CRP, PCT/ALB ratio, CRP/ALB ratio and GCS scores ( r = -0.821, -0.857, -0.750, -0.766, p < 0.001) and GOS scores ( r = -0.636, -0.628, -0.595, -0.628, p < 0.001) was revealed by Pearson correlation analysis. ALB was correlated positively with GCS score and GOS score ( r = 0.381, 0.413, p < 0.001). Multivariate logistic regression analysis exhibited that PCT/ALB ratio and CRP/ALB ratio were related to poor prognosis of CT patients ( p < 0.05). ROC curve analysis showed that the combined PCT/ALB ratio and CRP/ALB area under the curve (AUC) were 0.883 and 0.860, respectively, which were used to assess the severity and predict prognosis of patients with CT. CONCLUSIONS: PCT/ALB and CRP/ALB ratios were positively correlated with the severity and prognosis of patients with CT, and were risk factors for poor prognosis. Early determination of changes in PCT/ALB and CRP/ALB ratios had a certain clinical value for evaluating the condition and prognosis of CT patients.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Objective: To explore the clinical warning value of ischemic modified albumin (IMA) and IMA to human serum albumin (HSA) ratio (IMAR) in the development of pre-eclampsia (PE) and its severity. Methods: A total of 156 pregnant women with PE admitted to the Haidian District Maternal and Child Health Hospital of Beijing from April 2022 to March 2023 were collected as the PE group, and 156 healthy pregnant women with the same age and gestational age were matched as the control group. PE pregnant women were further divided into severe PE group (78 cases) and non-severe PE group (78 cases). Severe PE pregnant women were divided into emergency group (42 cases) and non-emergency group (36 cases) according to the disease progression time.All pregnant women were stratified according to their HSA levels (<30 g/L, 30-32 g/L, ≥32 g/L), and the peripheral blood IMA, HSA, and IMAR of pregnant women in different periods and subgroups were compared, and also the difference of IMA levels in umbilical artery blood. Bivariate correlation analysis was used to explore the correlation between severe PE and IMA or IMAR, and receiver operating characteristic (ROC) curves was used to analyze the diagnostic value of IMA, HSA, and IMAR for PE and severe PE. Results: (1) The IMA level and IMAR in peripheral serum of pregnant women in the PE group at diagnosis, and the IMA level in umbilical artery blood at delivery, and peripheral serum at 2 days after delivery were higher than those in the control group. The HSA level in peripheral serum was lower than that in the control group at diagnosis, and the differences were statistically significant (all P<0.001). (2) The IMA level and IMAR in the peripheral serum of pregnant women with severe PE were higher than those in the non-severe PE group at diagnosis, while the HSA level were lower than those in the non-severe PE group. The differences were statistically significant (all P<0.05). At diagnosis, the IMA level and IMAR in peripheral serum of pregnant women in the emergency group were higher than those in the non-emergency group, while the HSA level was lower than that in the non-emergency group. The differences were statistically significant (all P<0.05). When diagnosed, the peripheral serum IMA levels of pregnant women in the PE group were compared between subgroups with HSA<30 g/L, 30-32 g/L, ≥32 g/L, and there was no statistically significant difference (F=0.366, P=0.694). However, the IMAR was compared between the three subgroups, and the difference was statistically significant (F=28.544, P<0.001), which increased with the decrease of HSA levels. In the subgroup with HSA≥32 g/L, the peripheral serum IMA level and IMAR of pregnant women in the PE group were higher than those in the control group at diagnosis, and the differences were statistically significant (all P<0.001). (3) The severe PE manifestations positively correlated with peripheral serum IMAR at diagnosis include systolic blood pressure (r=0.279), mean arterial pressure (r=0.212), and urinary protein quantification (r=0.277), while the severe PE manifestations negatively correlated include HSA levels (r=-0.644) and newborn birth weight (r=-0.305), all of which were significantly correlated (P<0.05). (4) The area under curve (AUC) for IMAR diagnosis of PE was 0.875 (95%CI: 0.833-0.916), with the highest diagnostic efficiency at a cutoff value of 2.06, sensitivity of 72.5%, and specificity of 85.1%. The AUC for diagnosing severe PE was 0.871 (95%CI: 0.822-0.919), with the highest diagnostic efficacy at a cutoff value of 2.18, sensitivity of 72.3%, and specificity of 88.3%. The diagnostic efficacy of IMAR for PE and severe PE were higher than those of IMA and HSA levels. Conclusions: The level of IMA and IMAR in pregnant women with PE are higher than those in normal pregnant women. IMA and IMAR are correlated with the severity of PE, with IMAR changes occurring earlier and more significantly. IMAR could be considered as one of the evaluation indicators for the development of PE, or as a more sensitive PE severity warning indicator than HSA.

RESUMO

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.

RESUMO

OBJECTIVE: Serum albumin (ALB) plays a vital role in maintaining oncotic pressure and contributing to hemodynamic stability, with low levels associated with adverse outcomes in critically ill patients. This study aimed to assess the association between serum ALB concentrations and poor outcomes and the possible benefits of ALB supplementation. METHODS: A retrospective study involving 300 intensive care unit (ICU) patients. Albumin levels were recorded upon admission and throughout the stay, and patients were categorized based on a cutoff of 2.49 g/dl. The associations between low ALB levels and mortality were assessed using regression analysis. Additionally, it investigated the association of albumin supplementation with patient outcomes and mortality in specific patient populations. RESULTS: The mean age was 54.9 years, with 68% having sepsis. Patients with low baseline ALB concentrations exhibited higher overall mortality (71% vs. 52%) and 28-day mortality (50% vs. 39%). Adjusted analyses confirmed associations with mortality. Albumin supplementation was administered to 53% of the patients. Its use demonstrated potential benefits, particularly in reducing mortality, when given to specific groups, such as sepsis and hypoalbuminemia patients. DISCUSSION: The study confirms that low serum albumin levels are strongly associated with higher mortality rates in ICU patients. Albumin supplementation showed potential benefits, particularly in patients with sepsis and low albumin levels. Further analyses explored the dosage-response relationship and identified potential groups that would benefit from albumin supplementation. CONCLUSION: Albumin can play a major role in predicting mortality in critically ill patients. Moreover, ALB supplementation may improve survival, especially in resource-limited settings. Future research should refine protocols through clinical trials for optimal survival in critically ill patients.

RESUMO

The development of a fluorescent probe for pyriproxyfen (PPF) is crucial due to its potential threat to human health. However, the chemical inertness and low solubility of PPF present significant challenges for the detection of PPF in aqueous solutions using fluorescent probes. Herein, we have originally proposed a complex based on 2-(4-(dimethylamino)phenyl)-3-hydroxy-6,7-dimethoxy-4 H-chromen-4-one (HOF) and serum albumin (SA) as a dual-mode fluorescent probe, HOF@SA. This probe utilizes an indicator displacement assay (IDA) to release the dye HOF from the probe at low PPF concentrations (< 10 µM) and embeds the free dye HOF into the micelle of PPF at high concentrations (> 10 µM). This results in dual-mode fluorescent response characteristics for PPF: a turn-off response at low concentrations and a ratiometric response at high concentrations. An investigation of sensing behavior of HOF@SA for PPF detection exhibits rapid response (< 60 s), high sensitivity (LOD ∼4.7 ppb), high selectivity, and excellent visual detection capability (from cyan to yellow). Moreover, with the aid of a portable device, this method enables to analyze PPF in environmental and food samples. These results promote the advancement of a fluorescent probe approach for PPF analysis in environment and food.

RESUMO

This study investigated the association between serum albumin concentration and 12-weeks mortality of HIV/AIDS with late diagnosis in China. This retrospective cohort study included, 1079 inpatients diagnosis with late HIV/AIDS between January 2018 and December 2021. Disease progression was estimated based on the 12-weeks mortality rate. Cox proportional hazards regression models were used to evaluate the relationship between serum albumin levels and disease progression. The effects of serum albumin levels on mortality was estimated via Kaplan-Meier curves. The mortality risk decreased by 7% with every 1 g/L increase in serum albumin after adjustment ([HR] = 0.93, 95% CI: 0.88-0.97). Compared with that of the low (< 28 g/L) serum albumin group, the middle (28-34 g/L) group's mortality risk decreased by 70% (HR = 0.30, 95% CI: 0.15-0.59), and that of the high (≥ 34 g/L) group decreased by 40% (HR = 0.6, 95% CI: 0.29-1.23) after adjustment. Our findings suggest a positive correlation between the increase in serum albumin levels upon admission and a decrease in mortality at 12 weeks post-discharge among patients with late AIDS/HIV diagnosis. Further research is needed to characterize the role of serum albumin in 12-weeks mortality prevention in patients with a late diagnosis.
