RESUMO

BACKGROUND: Accurately estimating the prognosis of septic patients on arrival in the emergency department (ED) is clinically challenging. The lactate-to-albumin ratio (LAR) has recently been proposed to improve the predictive performance of septic patients admitted to the ICU. OBJECTIVES: This study aims to assess whether the LAR could be used as an early prognostic marker of 30-day mortality in patients with sepsis in the ED. METHODS: A prospective observational study was conducted in the ED of the Hospital of Merano. All patients with a diagnosis of sepsis were considered. The LAR was recorded on arrival in the ED. The primary outcome measure was mortality at 30 days. The predictive role of the LAR for mortality was evaluated with the area under the ROC curve, logistic regression adjusted for the Charlson Comorbidity Index value, National Early Warning Score, and Sequential Organ Failure score, and with decision tree analysis. RESULTS: 459 patients were enrolled, of whom 17% (78/459) died at 30 days. The median LAR of the patients who died at 30 days (0.78 [0.45-1.19]) was significantly higher than the median LAR of survivors (0.42 [0.27-0.65]) (p < 0.001). The discriminatory ability of the LAR for death at 30 days was 0.738, higher than that of lactate alone (0.692), and slightly lower than that of albumin alone (0.753). The decision trees confirmed the role of the LAR as an independent risk factor for mortality. CONCLUSION: The LAR can be used as an index to better predict the 30-day risk of death in septic patients.

RESUMO

BACKGROUND: Cadmium (Cd) is a toxic heavy metal that widely detected in environment and accumulated in kidney, posing a great threat to human health. However, there is a lack of systematic investigation of exposure profile and association of Cd exposure with renal function in the Chinese population. METHODS: Related articles were searched from PubMed, Web of Science, China National Knowledge Internet, and Wanfang to construct an aggregate exposure pathway (AEP) framework for Cd and to explore the correlation between Cd and renal function using random effects models. RESULTS: A total of 220 articles were included in this study, among which 215 investigated human exposure and 12 investigated the association of Cd with renal outcomes. The AEP framework showed that 96.5 % and 62.5 % of total Cd intake were attributed to dietary intake in nonsmokers and smokers, respectively. And 35.2 % originated from cigarette smoke inhalation in smokers. In human body, Cd was detected in blood, urine, placenta, etc. Although the concentrations of Cd in blood and urine from subjects living in polluted areas showed a sharp downward trend since the early 21st century, higher concentration of Cd in the environment and human body in polluted areas was found. Kidney was the target organ. The level of blood Cd was positively associated with urinary ß2-microglobulin [ß2-MG, r (95 % CI) = 0.12 (0.05, 0.19)], albumin [0.13 (0.06, 0.20)], and retinol-binding protein [RBP, 0.14 (0.03, 0.24)]. Elevated urinary Cd was correlated with increases in ß2-MG [0.22 (0.15, 0.29)], albumin [0.23 (0.16, 0.29)], N-acetyl-ß-d-glucosaminidase [NAG, 0.33 (0.22, 0.44)], and RBP [0.22 (0.14, 0.30)]. CONCLUSIONS: Foods and cigarette smoke were two major ways for Cd intake, and Cd induced renal injury in the Chinese population. This study enhanced the understanding of human exposure and nephrotoxicity of Cd, and emphasized the need for controlling Cd level in polluted areas.

RESUMO

1. Laying performance is an important economic trait in poultry. The blood is essential in transporting nutrients to the yolk and albumen and is necessary for egg formation.2. This study calculated the phenotypic relationships of duck egg quality, egg production efficiency and 22 serum parameters in the egg-laying stage. Using a variety of methodologies, a genome-wide association study (GWAS) was carried out to uncover the genetic foundations of the 22 serum biochemical markers of laying ducks.3. Spearman correlation coefficients between the egg production (226-329 per day) and the serum parameters were all weak, being less than 0.3. This analysis was done on 22 serum parameters, with total protein (TP), total triglycerides (TG), calcium (Ca) and phosphorous (P) having the highest correlation coefficients (r = 0.56-0.88). The coefficients for blood markers, such as total cholesterol (CHOL), total bilirubin (TBIL), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) varied from 0.70-0.94.4. Based on single-marker single-trait genome-wide analyses by a mixed linear model program of EMMAX, nine candidate genes were associated with enzyme traits (AST/ALT aspartate transaminase/glutamic-pyruvic transaminase, creatine kinase) and 19 candidate genes were associated with metabolism and protein-related serum parameters (glucose, total bile acid, uric acid (UA), albumin (ALB).5. The mvLMM (multivariate linear mixed model) of GEMMA software was used to carry out multiple trait integrated GWAS. Two candidate genes were found in the TP-TG-CA-P analysis and seven candidate genes in the CHOL_LDL-C_HDL-C_TBIL study. There was a high genetic correlation between the two groups.

RESUMO

Objective: To analyze the effects of self-management and continuous nursing on improving the incidence of complications in children with primary nephrotic syndrome. Methods: A retrospective analysis of 80 cases of children with primary nephrotic syndrome treated in our hospital from January 2019 to October 2022 was conducted. The patients were divided into a control group and an observation group, with 40 cases in each group. The control group received routine nursing, while the observation group received self-management and continuous nursing. After different nursing measures were taken in the two groups, the incidence of complications, the total satisfaction rate of patients' parents, quality of life scores, and the urinary albumin excretion rate before and after nursing between the two groups were analyzed. Results: (1) In comparison to the control group, the observation group had a lower incidence of complications (gastrointestinal discomfort, hypoglycemia, and abnormal liver function) (P < .05). (2) In comparison to the control group, the observation group had a higher total satisfaction rate of the patients' parents after nursing (P < .05). (3) Compared to the control group, the observation group reported higher quality of life scores (psychological function, spiritual vitality, and somatic function) after nursing (P < .05). (4) Compared to the control group, the observation group revealed higher self-management ability scores after nursing (P < .05). (5) After nursing, the urinary albumin excretion rate in the observation group was lower than that in the control group (P < .05). (6) In terms of disease recurrence rate after 1 month and 2 months of nursing, the observation group reported was lower rate of disease recurrence compared to the control group (P < .05). Conclusion: The application values of self-management and continuous nursing in children with primary nephrotic syndrome are significant.

RESUMO

The aim of this study is to develop a novel phantom for the evaluation of clinical CEST imaging settings, e.g., B0 and B1 field inhomogeneities, CEST contrast, and post-processing. We made a phantom composed of two slice sections: a grid section for local offset frequency evaluation and a sample section for CEST effect evaluation using different concentrations of an egg white albumin solution. On a 3 Tesla MR scanner, a phantom study was performed using CEST imaging; the mean B1 amplitudes were set at 1.2 and 1.9 µT, and CEST images with and without B0 corrections were acquired. Next, region of interest (ROI) analysis was performed for each slice. Then, CEST images with and without B0 corrections were compared at each B1 amplitude. The B0 corrected Z-spectrums at each local region in the grid section showed a shifting of the curve bottom to 0 ppm. Z-spectrum at B1 = 1.9 µT showed a broader curve shape than that at 1.2 µT. Moreover, MTRasym values at 3.5 ppm for each albumin sample at B1 = 1.9 µT were about two times higher than those at 1.2 µT. Our phantom enabled us to evaluate and optimize B0 inhomogeneity and the CEST effect at the B1 amplitude.

RESUMO

AIM: Albumin role as fluid resuscitation in sepsis remains understudied in low- and middle-income countries. This study aimed to evaluate the cost-effectiveness of intravenous (IV) Albumin compared to Crystalloids in sepsis patients using patient-level data in Jordan. METHODS: This was a retrospective cohort study of sepsis patients aged 18 or older admitted to intensive care units (ICU) at two major tertiary hospitals during the period 2018-2019. Patients information, type of IV fluid, and clinical outcomes were retrieved from medical records, and charges were retrieved from the billing system. A 90-day partitioned survival model with two health states (alive and dead) was constructed to estimate the survival of sepsis patients receiving either Albumin or Crystalloids as IV fluids for resuscitation. Overall survival was predicted by fitting a Weibull model on the patient-level data from the current study. To further validate the results, and to support the assessment of uncertainty, time-dependent transition probabilities of death at each cycle were estimated and used to construct a state-transition patient-level simulation model with 10,000 microsimulation trials. Adopting the healthcare system perspective, incremental cost-effectiveness ratios(ICERs) of Albumin versus Crystalloids were calculated in terms of the probability to be discharged alive from the ICU. Uncertainty was explored using probabilistic sensitivity analysis. RESULTS: In the partitioned survival model, Albumin was associated with an incremental cost of $1,007 per incremental1% in the probability of being discharged alive from the ICU. In the state-transition patient-level simulation model, ICER was $1,268 per incremental 1% in the probability of being discharged alive. Probabilistic sensitivity analysis showed that Albumin was favored at thresholds >$800 per incremental 1%in the probability of being discharged alive from the ICU. CONCLUSION: IV Albumin use in sepsis patients might not be cost-effective from the healthcare perspective of Jordan. This has important implications for policymakers to readdress Albumin prescribing practice in sepsis patients.


Sepsis is a life-threatening complication of infection, which usually requires resuscitation with intravenous fluids. Still, no conclusive evidence is available about the best fluid resuscitation to be used in sepsis patients especially in low- and middle-income countries. This study compared the costs and effectiveness of intravenous Albumin versus Crystalloids in sepsis patients. Findings from this study showed that resuscitation with Albumin is much more expensive compared to resuscitation with Crystalloids with no significant difference in mortality but with prolonged length of stay in the hospital and the intensive care unit. Decision makers are advised to change Albumin prescribing practices in a way that mitigates the associated clinical and financial burdens without compromising quality of care or resuscitate with Crystalloids.

RESUMO

BACKGROUND: Prior studies have suggested that the chronic inflammatory response has an important role in the pathophysiology of slow coronary flow phenomenon (SCFP). However, data are scarce regarding the role of plasma fibrinogen-to-albumin ratio (PFAR) in patients having SCFP without obstructive coronary artery disease (CAD). In this study, we investigated the relationship between PFAR and the presence of SCFP in patients without obstructive CAD. METHODS: From January 2021 to January 2023, we consecutively recruited 1085 patients without obstructive CAD according to the diagnostic and exclusion criteria. In total, SCFP was diagnosed in 70 patients. A 1:2 age-matched case-control study was then conducted using comparators without SCFP. Ultimately, this study enrolled 70 patients with angiographically normal coronary arteries and SCFP, along with 140 comparators with angiographically normal coronary arteries and normal coronary flow. Plasma fibrinogen and albumin levels were measured, and the PFAR was then calculated for each patient. RESULTS: PFARs were significantly greater in the SCFP group than in the comparators with normal coronary flow (82.8 ± 15.4 vs 73.1 ± 19.5, p < 0.001). PFAR increased with increasing numbers of vessels affected by SCFP. Multivariate logistic regression analysis showed that PFAR was an independent predictor of SCFP (odds ratio: 1.818, p = 0.015). Receiver operating characteristic (ROC) curve analysis indicated that PFAR showed a better predictive value of SCFP than fibrinogen or albumin, although not significantly (p > 0.05). CONCLUSION: PFAR is an independent predictor of SCFP in patients without obstructive CAD. PAFR could improve the predictive value of SFCP than albumin or fibrinogen alone, but not significantly.

RESUMO

INTRODUCTION: Hepatorenal syndrome (HRS), a special form of acute kidney failure, is a rare, acute, life-threatening complication of cirrhosis and has a very poor prognosis. Terlipressin (TERLIVAZ®) is the first and only pharmacological treatment approved by Food and Drug Administration (September 2022) to improve kidney function for adults with HRS with rapid reduction in kidney function. We constructed a decision analytic economic model to estimate the cost per complete response/HRS reversal of terlipressin + albumin from a United States hospital perspective. METHODS: A decision analytic model was developed to estimate the HRS treatment-related cost per response over an HRS hospitalization (assuming 14 days). Patients can experience either HRS reversal (complete response) or no HRS reversal (partial/no response) upon receipt of treatment. The efficacy, safety, and treatment duration data were from published head-to-head randomized international trials. Total treatment cost comprised drug acquisition and treatment-related costs (intensive care unit [ICU], dialysis [intermittent or continuous], pulse oximetry monitoring for terlipressin, and adverse events) sourced from the published literature. Cost per response, defined as the total treatment cost per HRS reversal was estimated for each treatment. The number needed to treat (NNT), defined as the number of patients treated to achieve HRS reversal in 1 additional patient, was estimated. RESULTS: Cost per response of terlipressin + albumin was lower than midodrine and octreotide + albumin (M&O) (US$85,315 vs. $467,794) and norepinephrine + albumin ($81,614 vs. $139,324). NNT for HRS reversal was 2 patients with terlipressin + albumin vs. M&O + albumin and 4 patients with terlipressin + albumin vs. norepinephrine + albumin, respectively. CONCLUSIONS: The analysis shows that terlipressin is a cost-effective treatment due to its higher efficacy and administration in the non-ICU setting. Terlipressin is a value-based treatment option for appropriate adults with HRS with rapid reduction in kidney function.


Hepatorenal syndrome, a functional, progressive kidney failure, is a life-threatening complication of cirrhosis. It is important to improve kidney function in patients who are hospitalized with hepatorenal syndrome considering the cost of treatment. This study assessed the cost per complete response/ hepatorenal syndrome reversal of terlipressin + albumin from a United States hospital perspective. This study shows that terlipressin improves kidney function with lower intensive care unit and dialysis costs compared with unapproved treatments. Terlipressin is a cost-effective, value-based treatment option for appropriate adults with hepatorenal syndrome with rapid reduction in kidney function.

RESUMO

•To assess the economic impact of implementing long-term albumin infusions in patients with cirrhosis and ascites in Brazil •Incremental cost per cirrhotic patient treated with long-term albumin was estimated based on the rates of complications and healthcare resource utilization from the ANSWER trial and local costs from the public and private healthcare system perspective in Brazil. •Implementation of long-term albumin could save up to 118,759 BRL and 189,675 BRL per patient treated in the public and private healthcare system setting, respectively. •Should results from the ANSWER trial translate into real-world effectiveness, addition of albumin to standard medical treatment could lead to improved clinical outcomes and reduced costs. Background - Cirrhosis is one of the final stages of chronic liver disease. Common causes of cirrhosis include alcoholism and viral hepatitis infections. Cirrhosis can progress from an asymptomatic, compensated phase to decompensation and the appearance of overt symptoms. There is no specific treatment for decompensated cirrhosis. The ANSWER trial positioned long-term albumin infusions as a potential treatment for patients with cirrhosis and uncomplicated ascites. Objective - This study assesses the economic impact of albumin infusions following the ANSWER trial regimen in Brazilian patients with decompensated cirrhosis from the public and private healthcare systems perspectives. Methods - The incremental cost per patient per year was calculated for standard medical treatment (SMT) plus long-term albumin infusions versus SMT alone. Costs of diuretics and albumin were obtained from Banco de Preços em Saúde and the Drug Market Regulation Chamber. Costs for complication and procedures were gathered from the published literature. Costs were transformed to 2021 Brazilian reals (BRL). Incidences of clinical complications and treatments were gathered from the ANSWER trial. Univariate sensitivity analysis was performed by increasing and decreasing all inputs by 20%. Results - The cost per patient per year was 118,759 BRL and 189,675 BRL lower for patients treated with SMT and albumin (compared to SMT only) for the public and private healthcare systems, respectively. The additional cost of albumin was offset by reduced complications and treatments (149,526 BRL and 249,572 BRL, respectively). The univariate sensitivity analysis showed cost savings for both healthcare systems in all the scenarios assessed. Conclusion - This economic analysis suggests that, if the ANSWER trial clinical outcomes translate into real-world effectiveness, addition of albumin infusions to SMT in patients with decompensated cirrhosis may lead to cost savings for the public and private healthcare systems in Brazil.

RESUMO

BACKGROUND: Hepatorenal syndrome (HRS) is characterized by severely reduced renal perfusion that precipitates rapid morbidity and mortality. Terlipressin is the only US Food and Drug Administration-approved treatment to improve kidney function for adults with HRS with a rapid reduction in kidney function. Prior to the approval of terlipressin, unapproved vasoconstrictive agents used in HRS treatment were octreotide/midodrine and norepinephrine with albumin. METHODS: A cohort decision-tree model representing a US hospital perspective assessed the clinical outcomes and direct medical costs (based primarily on hospital charges) of treating HRS with terlipressin + albumin (ALB) versus midodrine/octreotide (MID/OCT)+ALB, or norepinephrine (NorEp)+ALB. Treatment efficacy was defined by clinical response (complete/HRS reversal, partial, or no response) based on change of serum creatinine derived from published clinical trial reports. The proportions of patients with complete response were: terlipressin + ALB (36.2%), NorEp + ALB (19.1%), and MID/OCT + ALB (3.1%). Model outcomes included utilization of HRS-related healthcare resources (hospital and intensive care, outpatient and emergency department, dialysis, and transplantations), adverse events, and HRS-related mortality. Outcomes were assessed for the initial hospitalization in the base case and at 30, 60, and 90 days post-discharge. RESULTS: Total costs incurred over the initial hospitalization with terlipressin + ALB were lower vs NorEp + ALB, primarily due to higher ICU costs with NorEp + ALB ($7,433 vs $61,897). TER + ALB was associated with higher total costs vs MID/OCT + ALB due to higher pharmacy costs with terlipressin + ALB. The cost per complete response achieved of terlipressin + ALB ($451,605) was half that of NorEp + ALB ($930,571) and one-tenth that of MID/OCT + ALB ($4,942,123). CONCLUSIONS: HRS patients treated with terlipressin experienced better clinical outcomes and a lower cost per treatment response vs other unapproved treatments. ICU days and pharmacy costs were key cost drivers distinguishing the treatment groups. These outcomes suggest that terlipressin is cost-effective on the basis of total cost per response achieved.


Hepatorenal syndrome (HRS) is a rare and sudden life-threatening complication of the liver. Patients with HRS should receive immediate treatment with a drug that narrows blood vessels known as a vasoconstrictor. Terlipressin is the most common vasoconstrictor used for patients with HRS. Other common vasoconstrictors are midodrine with octreotide and norepinephrine. This study aimed to compare the cost of terlipressin with those of midodrine with octreotide and norepinephrine while also considering how well each of them worked to reverse HRS. This was done using an economic model. This economic model assessed the costs of the vasoconstrictor drugs and the costs of treating HRS, including costs attributable to drug acquisition, adverse events, organ transplantation, dialysis, and institutional encounters (i.e. hospitalization, ICU, emergency department, and outpatient visits). The magnitude of these costs depends on how well each drug reversed HRS. Based on inputs derived from their respective clinical trials, 36% of patients who were given terlipressin had a complete response (HRS was reversed), 19% of patients who were given norepinephrine had a complete response, and 3% of patients who were given midodrine with octreotide had a complete response. The total cost per patient was approximately $163,481 for terlipressin, $177,298 for norepinephrine, and $155,030 for midodrine with octreotide. When the costs were evaluated against how well the drugs worked to reverse HRS, the lowest cost per HRS reversal was $451,605 when treated with terlipressin. The cost per reversal for norepinephrine was $930,571 and for midodrine with octreotide was $4,942,123. These results show that terlipressin works well and is more cost-effective for US hospitals compared with the other unapproved treatment options for HRS with rapid reduction in kidney function.

RESUMO

OBJECTIVES: -To document the various laboratory and demographic/historical correlates of NT-proBNP levels in applicants for life insurance, and to explore the accuracy of a prediction model based on those variables. METHOD: -NT-proBNP blood test results were obtained from 1.34 million insurance applicants between the age of 50 and 85 years, beginning in 2003. Exploratory data analysis was carried out to document correlations with other laboratory variables, sex, age, and the presence of relevant diseases. Further, predictive models were used to quantify the proportion of the variance of NT-proBNP, which can be explained by a combination of these other, easier to determine variables. RESULTS: -NT-proBNP shows the expected, negative correlation with estimated glomerular filtration rate (eGFR) is markedly higher in those with a history of heart disease and is somewhat higher in those with a history of hypertension. A strong, unexpected, negative correlation between NT-proBNP and albumin was discovered. Of the variables evaluated, a multivariate adaptive regression spline (MARS) model automated selection procedure selected 7 variables (age, sex, albumin, eGFR, BMI, systolic blood pressure, cholesterol, and history of heart disease). Variable importance evaluation determined that age, albumin and eGFR were the 3 most important continuous variables in the prediction of NT-proBNP levels. An ordinary least squares (OLS) model using these same variables achieved a R-squared of 24.7%. CONCLUSION: -Expected ranges of NT-proBNP may vary substantially depending on the value of other variables in the prediction equation. Albumin is significantly negatively correlated with NT-proBNP levels. The reasons for this are unclear.

RESUMO

Understanding the causal impact that clinical risk factors have on healthcare-related costs is critical to evaluate healthcare interventions. Here, we used a genetically-informed design, Mendelian Randomization (MR), to infer the causal impact of 15 risk factors on annual total healthcare costs. We calculated healthcare costs for 373,160 participants from the FinnGen Study and replicated our results in 323,774 individuals from the United Kingdom and Netherlands. Robust causal effects were observed for waist circumference (WC), adult body mass index, and systolic blood pressure, in which a standard deviation increase corresponded to 22.78% [95% CI: 18.75-26.95], 13.64% [10.26-17.12], and 13.08% [8.84-17.48] increased healthcare costs, respectively. A lack of causal effects was observed for certain clinically relevant biomarkers, such as albumin, C-reactive protein, and vitamin D. Our results indicated that increased WC is a major contributor to annual total healthcare costs and more attention may be given to WC screening, surveillance, and mitigation.

RESUMO

INTRODUCTION: Hormonal contraceptives are artificial preparations that contain artificial progestins and Ethinylestradiol; these preparations are utilized by women of reproductive age to prevent pregnancy. Roughly a billion women in the world use some form of contraceptive worldwide. Despite the utility of these preparations, they are linked with several adverse effects, including disturbances of liver functionality and integrity. However, previous studies conducted to assess the association between hormonal contraceptive utilization and liver function tests reported conflicting results, and the effects remained a matter of concern. METHODS: The study enrolled a total of 264 participants, who were allocated into two groups. One group of hormonal contraceptive users who use the medication for a minimum of six months: Depot medroxyprogesterone acetate (DMPA), combined oral contraceptives (COC), Norplant, and Implant users and another age-matched non-user control group in a ratio of 1:1. A semi-structured questionnaire was used to collect socio-demographic, behavioral, and clinical data. Five ml serum blood sample was collected for liver function test analysis on a Beckman Coulter Clinical Chemistry analyzer (DXC 700 AU). Independent t-test was used to compare liver function tests of hormonal contraceptive users and non-user controls, whereas ANOVA followed by a Bonferroni post hoc test was used for intra- (between classes of contraceptives) and inter-group (between each class of contraceptives and controls) comparisons and to identify factors associated. RESULTS: Hormonal contraceptive users were observed to have a statistically significant higher mean value of liver enzymes assessed compared to non-user control groups: aspartate aminotransferase (AST) (47.07±14.79 versus 25.92±7.37; p <0.001), alanine aminotransferase (ALT) (35.83±13.76 versus 16.56 ± 5.03; p <0.001), alkaline phosphatase (ALP) (63.34±14.74 versus 45.41±14.34, p <0.001) and for γ-glutamyl transferase (GGT) (47.37±24.32 versus 19.45 ± 6.86 p <0.001). Similarly, the mean value of total and direct bilirubin (mg/dL) among HC users showed a statistically significant elevation (0.68 ± 0.22 against 0.32 ± 0.13, p <0.001) for total bilirubin and (0.14 ± 0.06 against 0.06 ± 0.03, p <0.001) for direct bilirubin respectively. However, no statistically significant result was observed in the mean values of total protein and albumin. For total protein (6.7 ± 0.89 versus 6.5 ± 1.15, p 0.07) and for albumin (5.4 ± 0.92 versus 5.3 ± 1.08; p 0.30). The current study also indicates the level of hepatic function test alteration is related to the type of hormonal contraceptives, duration of usage, and level of adherence to a specific class of contraceptives. CONCLUSION AND RECOMMENDATION: Hormonal contraceptive use was observed to affect hepatic function. Based on this finding, we strongly recommend to closely monitor liver function tests in women using hormonal contraceptives.

RESUMO

Objective: This study aims to analyze the prognostic risk factors influencing patient outcomes in cases of influenza-associated pneumonia. Methods: We comprehensively analysed clinical data from patients admitted to the First Affiliated Hospital of Wenzhou Medical University between December 2017 and April 2019. Patients with confirmed influenza-associated pneumonia, determined through nucleic acid detection in throat swabs or sputum samples, were included in the study. The collected data were meticulously analyzed to identify significant prognostic risk factors. Results: A total of 151 patients diagnosed with influenza-associated pneumonia were included in the final analysis, yielding a fatality rate of 19.87% (30/151). The application of multivariate regression analysis revealed that several independent risk factors significantly affected the prognosis of patients afflicted with influenza-associated pneumonia. These included lymphocyte count (L), oxygenation index (O), albumin (A), and urinary (U) levels. Receiver operating characteristic (ROC) curve analysis further elucidated the prognostic value of these factors. Specifically, the Composite Index LOAU (Lymphocyte, Oxygenation index, Albumin, Urinary) demonstrated a robust area under the curve (AUC) of 0.909 (95% CI: 0.851-0.950), surpassing the performance of established scoring systems, such as the pneumonia severity index (PSI) (AUC = 0.746), Apache II (AUC = 0.732), and CURB-65 (AUC = 0.662). These differences were statistically significant (P < .05). Conclusions: The prognosis of influenza-associated pneumonia can be effectively predicted by assessing peripheral blood parameters, including lymphocyte count, albumin level, urinary markers, and the oxygenation index upon admission. Notably, the Composite Index LOAU, as a comprehensive amalgamation of these factors, holds promising potential to enhance prognostic precision and management outcomes in cases of influenza-associated pneumonia.

RESUMO

AIM: To estimate the health economic impact of undertaking urine albumin-to-creatinine ratio (UACR) testing versus no UACR testing in early stages of chronic kidney disease (CKD) progression in patients with type 2 diabetes (T2D). METHODS: An economic model, taking a UK healthcare system perspective, estimated the impact of UACR testing on additional costs, clinical benefits measured as prevented dialyses and cardiovascular-related deaths, life years gained (LYg), LYg before kidney failure, and incremental cost-effectiveness ratio (ICER). Sixteen of the 18 Kidney Disease: Improving Global Outcomes (KDIGO) heatmap categories were considered separately, and grouped in health states according to CKD risk. Results were derived for current standard-of-care and emerging CKD therapies. RESULTS: The cohort that adhered to both UACR and estimated glomerular filtration rate (eGFR) testing guidelines in early stages of CKD (n = 1000) was associated with approximately 500 LYg before kidney failure onset; costing approximately £2.5 M. ICERs across the KDIGO heatmap categories were approximately £5,000. LIMITATIONS: This model used data from a comprehensive meta-analysis that was initiated more than 10 years ago (2009). While this was the most comprehensive source identified, recent changes in the treatment landscape, patient population and social determinants of CKD will not be captured. Furthermore, a narrow approach was taken, aligning included costs with UK NHS reference materials. This means that some direct and indirect drivers of costs in late-stage disease have been excluded. CONCLUSIONS: UACR testing in the early stages of CKD is cost effective in T2D patients. Emerging therapies with the potential to slow CKD progression, mean that optimal monitoring through UACR/eGFR testing will become increasingly important for accurate identification and timely treatment initiation, particularly for the highest-risk A3 category.

RESUMO

BACKGROUND: Valvular heart disease (VHD) can cause damage to extra-cardiac organs, and lead to multi-organ dysfunction. However, little is known about the cardio-renal-hepatic co-dysfunction, as well as its prognostic implications in patients with VHD. The study sought to develop a multi-biomarker index to assess heart, kidney, and liver function in an integrative fashion, and investigate the prognostic role of cardio-renal-hepatic function in VHD. METHODS: Using a large, contemporary, prospective cohort of 6004 patients with VHD, the study developed a multi-biomarker score for predicting all-cause mortality based on biomarkers reflecting heart, kidney, and liver function (N-terminal pro-B-type natriuretic peptide [NT-proBNP], creatinine, and albumin). The score was externally validated in another contemporary, prospective cohort of 3156 patients with VHD. RESULTS: During a median follow up of 731 (704-748) days, 594 (9.9%) deaths occurred. Increasing levels of NT-proBNP, creatinine, and albumin were independently and monotonically associated with mortality, and a weighted multi-biomarker index, named the cardio-renal-hepatic (CRH) score, was developed based on Cox regression coefficients of these biomarkers. The CRH score was a strong and independent predictor of mortality, with 1-point increase carrying over two times of mortality risk (overall adjusted hazard ratio [95% confidence interval]: 2.095 [1.891-2.320], P < 0.001). The score provided complementary prognostic information beyond conventional risk factors (C index: 0.78 vs 0.81; overall net reclassification improvement index [95% confidence interval]: 0.255 [0.204-0.299]; likelihood ratio test P < 0.001), and was identified as the most important predictor of mortality by the proportion of explainable log-likelihood ratio χ2 statistics, the best subset analysis, as well as the random survival forest analysis in most types of VHD. The predictive performance of the score was also demonstrated in patients under conservative treatment, with normal left ventricular systolic function, or with primary VHD. It achieved satisfactory discrimination (C index: 0.78 and 0.72) and calibration in both derivation and validation cohorts. CONCLUSIONS: A multi-biomarker index was developed to assess cardio-renal-hepatic function in patients with VHD. The cardio-renal-hepatic co-dysfunction is a powerful predictor of mortality and should be considered in clinical management decisions.

RESUMO

PURPOSE: This study aims to assess peripapillary retinal nerve fiber layer thickness (pRNFLT) and peripapillary vessel density (PVD) in patients with newly diagnosed active and inactive systemic lupus erythematosus (SLE) by optical coherence tomography (OCT) and OCT angiography (OCTA). METHODS: This is a cross-sectional study, in which 77 newly diagnosed SLE patients without ocular symptoms (including 36 active SLE patients and 41 inactive SLE patients) and 72 age- and gender-matched healthy subjects were recruited. All participants underwent OCT and OCTA to evaluate pRNFLT, PVD, and radial peripapillary capillary density (RPCD), respectively. Clinical data at the time of initial diagnosis of SLE, including erythrocyte, leukocyte, platelet, albumin-globulin ratio, erythrocyte sedimentation rate, C-reactive protein, serum complement 3, serum complement 4, anti-dsDNA antibody, and 24-h proteinuria, were collected. RESULTS: No difference was found in pRNFLT between active SLE patients, and healthy controls, average pRNFLT, superonasal RNFLT, and inferonasal pRNFLT were reduced in inactive SLE patients than in healthy controls (p≤0.008). Temporal PVD, inferotemporal PVD, and inferotemporal RPCD in active SLE patients were significantly lower than those in healthy controls (p≤0.043). There also was a trend towards lower temporal RPCD in active SLE than healthy controls (p=0.089). Average PVD, average RPCD, superonasal RPCD, inferonasal RPCD, and inferotemporal RPCD were decreased in inactive SLE patients than in healthy controls (p≤0.047). Additionally, inferotemporal RPCD in active SLE patients was positively associated with albumin-globulin ratio (p=0.041). Temporal RPCD was negatively correlated with anti-dsDNA antibody (p=0.012) and 24-h proteinuria (p=0.006). CONCLUSIONS: PRNFL and PVD damage existed in newly diagnosed SLE patients without ocular symptoms. Temporal and inferotemporal RPCD were associated with the laboratory indicators of impaired renal function in active SLE patients, respectively.

RESUMO

The assessment of liver function is crucial in predicting the risk of post-hepatectomy liver failure (PHLF) in patients undergoing liver resection, especially in cases of hepatocellular carcinoma (HCC) which is often associated with cirrhosis. There are currently no standardized criteria for predicting the risk of PHLF. Blood tests are often the first- and least invasive expensive method for assessing hepatic function. The Child-Pugh score (CP score) and the Model for End Stage Liver Disease (MELD) score are widely used tools for predicting PHLF, but they have some limitations. The CP score does not consider renal function, and the evaluation of ascites and encephalopathy is subjective. The MELD score can accurately predict outcomes in cirrhotic patients, but its predictive capabilities diminish in non-cirrhotic patients. The albumin-bilirubin score (ALBI) is based on serum bilirubin and albumin levels and allows the most accurate prediction of PHLF for HCC patients. However, this score does not consider liver cirrhosis or portal hypertension. To overcome this limitation, researchers suggest combining the ALBI score with platelet count, a surrogate marker of portal hypertension, into the platelet-albumin-bilirubin (PALBI) grade. Non-invasive markers of fibrosis, such as FIB-4 and APRI, are also available for predicting PHLF but they focus only on cirrhosis related aspects and are potentially incomplete in assessing the global liver function. To improve the predictive power of the PHLF of these models, it has been proposed to combine them into a new score, such as the ALBI-APRI score. In conclusion, blood test scores may be combined to achieve a better predictive value of PHLF. However, even if combined, they may not be sufficient to evaluate liver function and to predict PHLF; thus, the inclusion of dynamic and imaging tests such as liver volumetry and ICG r15 may be helpful to potentially improve the predictive capacity of these models.

RESUMO

OBJECTIVES: This study was undertaken to evaluate the prescribing practice of albumin in the intensive care unit (ICU) and to compare the clinical and economic outcomes associated with intravenous (IV) albumin compared to crystalloids in the ICU. METHODS: This was a retrospective cohort study of ICU adult patients admitted to King Abdullah University Hospital during 2018-2019. Patient demographics, clinical characteristics, and admission charges were retrieved from medical records and billing system. Survival analysis, multivariable regression models, and propensity score matching estimator were performed to evaluate the impact of IV resuscitation fluid types on the clinical and economic outcomes. RESULTS: Albumin administration in the ICU was associated with significantly lower hazards of ICU death (HR = 0.57; P value <0.001), but without improving overall death probability compared to crystalloids. Albumin was associated with significant prolongation in the ICU length of stay (5.86 days; P value <0.001). Only 88 patients (24.3%) were prescribed albumin for Food and Drug Administration (FDA)-approved indications. Admission charges were significantly higher for patients treated with albumin (p value <0.001). CONCLUSIONS: IV Albumin use in the ICU was not associated with significant improvement in clinical outcomes, but with a remarkable increase in economic burden. The majority of patients received albumin for non-FDA-approved indications.

RESUMO

BACKGROUND AND AIM: Hepatic decompensation is a major complication of liver cirrhosis. We validated the predictive performance of the newly proposed CHESS-ALARM model to predict hepatic decompensation in patients with hepatitis B virus (HBV)-related cirrhosis and compared it with other transient elastography (TE)-based models such as liver stiffness-spleen size-to-platelet (LSPS), portal hypertension (PH), varices risk scores, albumin-bilirubin (ALBI), and albumin-bilirubin-fibrosis-4 (ALBI-FIB-4). METHODS: Four hundred eighty-two patients with HBV-related liver cirrhosis between 2006 and 2014 were recruited. Liver cirrhosis was clinically or morphologically defined. The predictive performance of the models was assessed using a time-dependent area under the curve (tAUC). RESULTS: During the study period, 48 patients (10.0%) developed hepatic decompensation (median 93 months). The 1-year predictive performance of the LSPS model (tAUC = 0.8405) was higher than those of the PH model (tAUC = 0.8255), ALBI-FIB-4 (tAUC = 0.8168), ALBI (tAUC = 0.8153), CHESS-ALARM (tAUC = 0.8090), and variceal risk score (tAUC = 0.7990). The 3-year predictive performance of the LSPS model (tAUC = 0.8673) was higher than those of the PH risk score (tAUC = 0.8670), CHESS-ALARM (tAUC = 0.8329), variceal risk score (tAUC = 0.8290), ALBI-FIB-4 (tAUC = 0.7730), and ALBI (tAUC = 0.7451). The 5-year predictive performance of the PH risk score (tAUC = 0.8521) was higher than those of the LSPS (tAUC = 0.8465), varices risk score (tAUC = 0.8261), CHESS-ALARM (tAUC = 0.7971), ALBI-FIB-4 (tAUC = 0.7743), and ALBI (tAUC = 0.7541). However, there was no significant difference in the predictive performance among all models at 1, 3, and 5 years (P > 0.05). CONCLUSIONS: The CHESS-ALARM score was able to reliably predict hepatic decompensation in patients with HBV-related liver cirrhosis and showed similar performance to the LSPS, PH, varices risk scores, ALBI, and ALBI-FIB-4.
