[PMID: 39396704 DOI: 10.1016/j.clnesp.2024.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2024] [Revised: 10/01/2024] [Accepted: 10/06/2024] [Indexed: 10/15/2024]
Abstract
BACKGROUND & AIMS The value of serum albumin might be underestimated, especially in cancer patients. We thus aimed to evaluate the association between serum albumin level at hospital admission and clinical outcomes in hospitalized patients with cancer. METHODS This is a retrospective, cross-sectional, and real-world data analysis. Hospitalized adult patients with malignant cancer were recruited from two tertiary hospitals. Serum level of albumin, which was measured within 24 h after hospital admission, was the exposure. Length of hospital stays (LOS) was the primary and all-cause in-hospital mortality was the secondary outcomes. Other information, including age, sex, types of cancer, history of hypertension and diabetes, surgery, blood routine test, liver and renal function, and dietary intake, were also abstracted from medical records. RESULTS A total number of 5187 adult patients with cancer (2949 were men and 2238 women; average age 61.6 ± 12.4 years and average albumin 40.3 ± 5.2 g/L) were included. The prevalence of hypoalbuminemia was 12.2 % (634/5187). Older patients, patients with liver injury, anemia, and with high level of WBC were positively, while those with overweight and high level of total triglycerides, were negatively associated with hypoalbuminemia. After adjustment of covariates, hypoalbuminemia was significantly associated with longer LOS in the current study. The increase of 5 g/L in serum level of albumin could result in 1.09 days (95%CI: -1.38, -0.80 days) shorter in LOS. The increase of 5 g/L in serum level of albumin was also associated with 45 % lower in risk of mortality (OR = 0.55; 95 % CI: 0.43, 0.7) after fully adjustment. CONCLUSIONS Serum albumin level at admission was associated with both LOS and mortality in patients with malignant cancer.

Abstract
INTRODUCTION Hypoalbuminemia is predictive of mortality in critically ill patients, especially those with cardiac etiologies of illness. The objective of this study was to determine the association of albumin level pre-cannulation for veno-arterial (V-A) extracorporeal membrane oxygenation (ECMO) and important clinical hospital outcomes. METHODS This was a retrospective, observational cohort study of albumin levels in patients with cardiogenic shock requiring V-A ECMO between December 2015 and August 2021 in a single, high-volume ECMO center. The primary outcome was in-hospital mortality. RESULTS Of 434 patients assessed, 318 were included. The overall mean pre-ECMO albumin was 3 ± 0.8 g/dL and mean albumin at 72 hours post-cannulation was 2.7 ± 0.5 g/dL. For patients with pre-ECMO albumin ≤3 g/dL vs. >3 g/dL, in-hospital mortality was 44.9% vs. 27.5%, respectively (p = .002). In multivariable logistic regression analysis, higher albumin (per 1 g/dL increase) at time of V-A ECMO initiation was associated with decreased odds of in-hospital mortality (OR, 0.68; 95% CI, 0.48-0.96; p = .03). Patients with a pre-ECMO albumin ≤3 g/dL required significantly more platelet transfusions and had higher incidence of gastrointestinal bleeding during V-A ECMO support (both p < .05). CONCLUSIONS Hypoalbuminemia at time of cannulation is significantly associated with in-hospital mortality and ECMO-related complications including platelet transfusion and gastrointestinal bleeding. Albumin levels at the time of consideration of V-A ECMO may serve as a key prognostic indicator and may assist in effective decision-making regarding this invasive and costly resource.

Badawy AAB. The role of nonesterified fatty acids in cancer biology: Focus on tryptophan and related metabolism. Biochim Biophys Acta Mol Cell Biol Lipids 2024; 1869:159531.

Abstract
Plasma nonesterified fatty acids (NEFA) are elevated in cancer, because of decreased albumin levels and of fatty acid oxidation, and increased fatty acid synthesis and lipolysis. Albumin depletion and NEFA elevation maximally release albumin-bound tryptophan (Trp) and increase its flux down the kynurenine pathway, leading to increased production of proinflammatory kynurenine metabolites, which tumors use to undermine T-cell function and achieve immune escape. Activation of the aryl hydrocarbon receptor by kynurenic acid promotes extrahepatic Trp degradation by indoleamine 2,3-dioxygenase and leads to upregulation of poly (ADP-ribose) polymerase, activation of which and also of SIRT1 (silent mating type information regulation 2 homolog 1) could lead to depletion of NAD+ and ATP, resulting in cell death. NEFA also modulate heme synthesis and degradation, changes in which impact homocysteine metabolism and production of reduced glutathione and hydrogen sulphide. The significance of the interactions between heme and homocysteine metabolism in cancer biology has received little attention. Targeting Trp disposition in cancer to prevent the NEFA effects is suggested.

Assessment of Albumin Usage Patterns and Appropriateness in a Comprehensive Cancer Centre: A retrospective study in Jordan. Sultan Qaboos Univ Med J 2024; 24:354-359. [PMID: 39234319 PMCID: PMC11370948 DOI: 10.18295/squmj.6.2024.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 04/02/2024] [Accepted: 04/21/2024] [Indexed: 09/06/2024] Open
Abstract
Objectives Albumin is commonly used for various indications; however, there is conflicting data regarding its appropriate use in different clinical cases. This study aimed to determine the pattern and appropriateness of albumin use among cancer patients at the King Hussein Cancer Center in Jordan. Methods A retrospective analysis was conducted on adult cancer patients who were prescribed albumin between January 2019 and July 2020 in both outpatient and inpatient settings. Data collected included demographics, prescribing services, indications and dosing regimens. A literature review was performed using PubMed to assess the appropriateness of albumin indications and dosing regimens against current guidelines, drug information resources and the package insert. Results Albumin was prescribed to 1,361 patients during the study period. Each patient received an average of 74.4 ± 89 g of albumin for an average of 2.6 ± 1.8 days. Albumin use was deemed appropriate in 69% of the patients. The critical care service accounted for the highest albumin consumption, with 37% of prescriptions for septic shock. Inappropriate use of albumin was most prevalent in the medical solid tumour services (40.8% of prescriptions), primarily for edema (28%). Conclusion To the best of the author's knowledge, this study is the first to evaluate albumin use in a large cohort of oncology patients. Approximately one-third of the albumin prescriptions were considered inappropriate. Continuous education on appropriate usage and regular evaluations of guideline adherence are essential to ensure proper utilisation of albumin in cancer care.

Predictive value of abnormal blood tests for detecting cancer in primary care patients with nonspecific abdominal symptoms: A population-based cohort study of 477,870 patients in England. PLoS Med 2024; 21:e1004426. [PMID: 39078806 PMCID: PMC11288431 DOI: 10.1371/journal.pmed.1004426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Accepted: 06/13/2024] [Indexed: 08/02/2024] Open
Abstract
BACKGROUND Identifying patients presenting with nonspecific abdominal symptoms who have underlying cancer is a challenge. Common blood tests are widely used to investigate these symptoms in primary care, but their predictive value for detecting cancer in this context is unknown. We quantify the predictive value of 19 abnormal blood test results for detecting underlying cancer in patients presenting with 2 nonspecific abdominal symptoms. METHODS AND FINDINGS Using data from the UK Clinical Practice Research Datalink (CPRD) linked to the National Cancer Registry, Hospital Episode Statistics and Index of Multiple Deprivation, we conducted a population-based cohort study of patients aged ≥30 presenting to English general practice with abdominal pain or bloating between January 2007 and October 2016. Positive and negative predictive values (PPV and NPV), sensitivity, and specificity for cancer diagnosis (overall and by cancer site) were calculated for 19 abnormal blood test results co-occurring in primary care within 3 months of abdominal pain or bloating presentations. A total of 9,427/425,549 (2.2%) patients with abdominal pain and 1,148/52,321 (2.2%) with abdominal bloating were diagnosed with cancer within 12 months post-presentation. For both symptoms, in both males and females aged ≥60, the PPV for cancer exceeded the 3% risk threshold used by the UK National Institute for Health and Care Excellence for recommending urgent specialist cancer referral. Concurrent blood tests were performed in two thirds of all patients (64% with abdominal pain and 70% with bloating). In patients aged 30 to 59, several blood abnormalities updated a patient's cancer risk to above the 3% threshold: For example, in females aged 50 to 59 with abdominal bloating, pre-blood test cancer risk of 1.6% increased to: 10% with raised ferritin, 9% with low albumin, 8% with raised platelets, 6% with raised inflammatory markers, and 4% with anaemia. Compared to risk assessment solely based on presenting symptom, age and sex, for every 1,000 patients with abdominal bloating, assessment incorporating information from blood test results would result in 63 additional urgent suspected cancer referrals and would identify 3 extra cancer patients through this route (a 16% relative increase in cancer diagnosis yield). Study limitations include reliance on completeness of coding of symptoms in primary care records and possible variation in PPVs if extrapolated to healthcare settings with higher or lower rates of blood test use. CONCLUSIONS In patients consulting with nonspecific abdominal symptoms, the assessment of cancer risk based on symptoms, age and sex alone can be substantially enhanced by considering additional information from common blood test results. Male and female patients aged ≥60 presenting to primary care with abdominal pain or bloating warrant consideration for urgent cancer referral or investigation. Further cancer assessment should also be considered in patients aged 30 to 59 with concurrent blood test abnormalities. This approach can detect additional patients with underlying cancer through expedited referral routes and can guide decisions on specialist referrals and investigation strategies for different cancer sites.

Abstract
Voriconazole (VRC) displays highly variable pharmacokinetics impacting treatment efficacy and safety. To provide evidence for optimizing VRC therapy regimens, the authors set out to determine the factors impacting VRC steady-state trough concentration (Cmin) in patients with various albumin (Alb) level. A total of 275 blood samples of 120 patients and their clinical characteristics and genotypes of CYP2C19, CYP3A4, CYP3A5, CYP2C9, FMO3, ABCB1, POR, NR1I2 and NR1I3 were included in this study. Results of multivariate linear regression analysis demonstrated that C-reactive protein (CRP) and total bilirubin (T-Bil) were predictors of the VRC Cmin adjusted for dose in patients with hypoalbuminemia (Alb < 35 g/L) (R2 = 0.16, P < 0.001). Additionally, in patients with normal albumin level (Alb ≥ 35 g/L), it resulted in a significant model containing factors of the poor metabolizer (PM) CYP2C19 genotype and CRP level (R2 = 0.26, P < 0.001). Therefore, CRP and T-Bil levels ought to receive greater consideration than genetic factors in patients with hypoalbuminemia.

Abstract
Nanoparticles as cancer therapeutic carrier fail in clinical translation due to complex biological environments in vivo consisting of electrolytes and proteins which render nanoparticle aggregation and unable to reach action site. This review identifies the desirable characteristics of nanoparticles and their constituent materials that prevent aggregation from site of administration (oral, lung, injection) to target site. Oral nanoparticles should ideally be 75-100 nm whereas the size of pulmonary nanoparticles minimally affects their aggregation. Nanoparticles generally should carry excess negative surface charges particularly in fasting state and exert steric hindrance through surface decoration with citrate, anionic surfactants and large polymeric chains (polyethylene glycol and polyvinylpyrrolidone) to prevent aggregation. Anionic as well as cationic nanoparticles are both predisposed to protein corona formation as a function of biological protein isoelectric points. Their nanoparticulate surface composition as such should confer hydrophilicity or steric hindrance to evade protein corona formation or its formation should translate into steric hindrance or surface negative charges to prevent further aggregation. Unexpectedly, smaller and cationic nanoparticles are less prone to aggregation at cancer cell interface favoring endocytosis whereas aggregation is essential to enable nanoparticles retention and subsequent cancer cell uptake in tumor microenvironment. Present studies are largely conducted in vitro with simplified simulated biological media. Future aggregation assessment of nanoparticles in biological fluids that mimic that of patients is imperative to address conflicting materials and designs required as a function of body sites in order to realize the future clinical benefits.

Abstract
Objectives Our research aimed to examine the characteristics of palliative oncology patients hospitalised through an emergency to look for the symptom profile, characteristics of dyselectrolytemia and blood investigations, and possible associations with mortality. Materials and Methods After institutional review board approval, a retrospective, observational study of patients hospitalised in our tertiary care specialty oncology hospital was undertaken. Records of hospitalised cancer patients admitted from the emergency department under palliative care from January 2019 to October 2021 were examined. As all admissions during this period were through emergency due to institution COVID-19 protocols, all elective admissions were excluded from the study. Data collected included patient characteristics, blood investigations, and comorbid history of systemic diseases and factors that could be associated with electrolyte imbalance. Results There were 157 emergency admissions during the study period. A majority were patients with solid tumours (92.4%). Pain was the most frequent cardinal symptom, along with other symptoms (68/157) or in isolation (33/157), followed by reduced oral intake (32/157) and altered sensorium (24/157). sixty-six patients died within the hospitalisation period. On long-term follow-up, only 8 (5.1%) were surviving. Hyponatraemia (43%), Hypoalbuminaemia (66%), and altered renal function (33.1%) were prevalent. We observed a weak positive correlation between sodium levels and outcome (r = 0.199, P = 0.016) and a strong positive correlation between albumin levels and survival outcomes (r = 0.329, P = 0.000). Patients with normal albumin had a higher chance of survival (odds ratio: 33.1225, 95% confidence interval: 3.415-321.20, P = 0.003). Conclusion Pain-reduced oral intake and altered sensorium are common emergency symptoms in oncology palliative care. Mortality is high in these patients. Hyponatraemia, hypoalbuminaemia, and deranged renal functions were commonly seen. Normal sodium and albumin levels were associated with higher chances of survival, and the association was strong for serum albumin levels. This may have prognostic utility.

Abstract
BACKGROUND Sarcopenia is associated with poor prognosis in metastatic colorectal cancer (mCRC) patients. PURPOSE To investigate the prognostic value of body composition measurement changes measured by computed tomography (CT) in mCRC patients. MATERIAL AND METHODS The abdominal skeletal muscle density (SMD) and skeletal muscle (SMI) indices, as well as the visceral (VATI) and subcutaneous fat tissue (SATI) indices, were calculated by automatic segmentation method on the abdominal CT images obtained before (n = 71) and after chemotherapy (n = 52). Skeletal muscle gauge (SMG = SMD × SMI) was calculated. We calculated the percentage change of body composition measurements with respect to the first measurements. The cutoff value for the change in SMG was calculated by receiver operating characteristic analysis. Kaplan-Meier and Cox regression analyses were performed to calculate the prognostic value of age, gender, tumor location, metastasis site and carcinoembriogenic antigen (CEA) elevation, hypoalbuminemia, body mass index classification, presence of sarcopenia and SMG changes in terms of overall survival. RESULTS There was a significant association between SMG change and mortality (P = 0.037). According to survival analyses, highly decreased SMG, hypoalbuminemia and CEA variables of the patients were the significant factors (P < 0.001, P = 0.015 and P = 0.019, respectively). According to multivariate regression analysis, hypoalbuminemia (P = 0.004, hazard ratio = 3.60) and highly decreased SMG (P < 0.001, hazard ratio = 14.98) were found to be significant prognostic factors together. CONCLUSION In mCRC patients, hypoalbuminemia and highly decreased SMG are significant prognostic factors for overall survival. Therefore, we suggest that the change in SMG calculated in follow-up images should also be evaluated in the prognosis estimation of this patient group.

Abstract
Albumin is the most abundant circulating protein and provides about 70% of the plasma oncotic power. The molecule also carries many other biological functions (binding, transport and detoxification of endogenous and exogenous compounds, antioxidation, and modulation of inflammatory and immune responses). Hypoalbuminemia is a frequent finding in many diseases, representing usually only a biomarker of poor prognosis rather than a primary pathophysiological event. Despite that, albumin is prescribed in many conditions based on the assumption that correction of hypoalbuminemia would lead to clinical benefits for the patients. Unfortunately, many of these indications are not supported by scientific evidence (or have been even disproved), so that a large part of albumin use is nowadays still inappropriate. Decompensated cirrhosis is the clinical area where albumin administration has been extensively studied and solid recommendations can be made. Besides prevention and treatment of acute complications, long-term albumin administration in patients with ascites has emerged in the last decade has a potential new disease-modifying treatment. In non-hepatological settings, albumin is widely used for fluid resuscitation in sepsis and critical illnesses, with no clear superiority over crystalloids. In many other conditions, scientific evidence supporting albumin prescription is weak or even absent. Thus, given its high cost and limited availability, action is needed to avoid the use of albumin for inappropriate and futile indications to ensure its availability in those conditions for which albumin has been demonstrated to have a real effectiveness and an advantage for the patient.

Toxins (Basel) 2023; 15:619. [PMID: 37888650 PMCID: PMC10610632 DOI: 10.3390/toxins15100619] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 10/06/2023] [Accepted: 10/11/2023] [Indexed: 10/28/2023] Open
Abstract
Despite more than 80 years of use in a number of conditions, including in critically ill patients, comments have recently arisen regarding the safety and efficacy of human serum albumin (HSA) as a therapeutic product and stabilizer/excipient in botulinum neurotoxins. This review summarizes the literature on the safety of HSA. Beyond decades of safe use, the largest clinical dataset of HSA safety is a large meta-analysis of HSA supplier data, which found only an extremely remote risk of serious adverse events across millions of doses of therapeutic concentrations of HSA. There is a paucity of literature identifying HSA-specific adverse events when used as a stabilizer/excipient; however, studies of HSA-containing botulinum neurotoxins (BoNTs) suggest that adverse events are not related to HSA. Polysorbates, which are synthetically produced and not physiologically inert, are contained in pending or new-to-market BoNT formulations. In contrast to HSA, evidence exists to suggest that polysorbates (particularly PS20/PS80) can cause serious adverse events (e.g., hypersensitivity, anaphylaxis, and immunogenicity).

Abstract
Critically ill patients have increased variability in beta-lactam antibiotic (beta-lactam) exposure due to alterations in their volume of distribution and elimination. Therapeutic drug monitoring (TDM) of beta-lactams, as a dose optimization and individualization tool, has been recommended to overcome this variability in exposure. Despite its potential benefit, only a few centres worldwide perform beta-lactam TDM. An important reason for the low uptake is that the evidence for clinical benefits of beta-lactam TDM is not well established. TDM also requires the availability of specific infrastructure, knowledge and expertise. Observational studies and systematic reviews have demonstrated that TDM leads to an improvement in achieving target concentrations, a reduction in potentially toxic concentrations and improvement of clinical and microbiological outcomes. However, a small number of randomized controlled trials have not shown a mortality benefit. Opportunities for improved study design are apparent, as existing studies are limited by their inclusion of heterogeneous patient populations, including patients that may not even have infection, small sample size, variability in the types of beta-lactams included, infections caused by highly susceptible bacteria, and varied sampling, analytical and dosing algorithm methods. Here we review the fundamentals of beta-lactam TDM in critically ill patients, the existing clinical evidence and the practical aspects involved in beta-lactam TDM implementation.

Prognostic Value of the Red Blood Cell Distribution Width-to-Albumin Ratio in Critically Ill Older Patients with Acute Kidney Injury: A Retrospective Database Study. Emerg Med Int 2023; 2023:3591243. [PMID: 37051465 PMCID: PMC10085652 DOI: 10.1155/2023/3591243] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Revised: 03/10/2023] [Accepted: 03/23/2023] [Indexed: 04/05/2023] Open
Abstract
Background. There is no evidence suggesting that red blood cell distribution width-to-albumin ratio (RA) predicts outcomes in severely ill older individuals with acute kidney injury (AKI). We hypothesized that RA is associated with all-cause mortality in critically ill older patients with AKI. Methods. We recorded demographics, laboratory tests, comorbidities, vital signs, and other clinical information from the MIMIC-III V1.4 dataset. The primary endpoint was 90-day all-cause mortality, and the secondary endpoints were 30-day mortality, one-year mortality, renal replacement treatment (RRT), duration of stay in the intensive care unit (ICU), sepsis, and septic shock. We generated Cox proportional hazards and logistic regression models to determine RA’s prognostic values and subgroup analyses to determine the subgroups’ mortality. We conducted a Pearson correlation analysis on RA and C-reactive protein (CRP) in the cohort of patients from the Second Affiliated Hospital of Wenzhou Medical University. Results. A total of 6,361 patients were extracted from MIMIC-III based on the inclusion and exclusion criteria. RA levels directly and linearly correlated with 90-day all-cause mortality. After controlling for ethnicity, gender, age, and other confounding variables in multivariate analysis, higher RA was significantly associated with an increased risk of 30-day, 90-day, and one-year all-cause mortality as opposed to the reduced levels of RA (tertile 3 vs. tertile 1: hazard ratios (HRs), 95% confidence intervals (CIs): 1.70, 1.43–2.01; 1.90, 1.64–2.19; and 1.95, 1.72–2.20, respectively). These results suggested that elevated levels of RA were linked to an elevated risk of 30-day, 90-day, and one-year all-cause death. There was a similar trend between RA and the use of RRT, length of stay in ICUs, sepsis, and septic shock. The subgroup analysis did not reveal any considerable interplay among strata. When areas under the curve were compared, RA was a weaker predictor than the SAPS II score but a stronger predictor than red blood cell distribution width (RDW) or albumin alone (
); RA combined with SAPS II has better predictive power than SAPS II alone (
). The Second Affiliated Hospital of Wenzhou Medical University cohort showed that CRP positively correlated with RA, with a coefficient of 0.2607 (
). Conclusions. RA was an independent prognostic predictor in critically ill older patients with AKI, and greater RA was linked to a higher probability of death. The risk of AKI is complicated when RRT occurs; sepsis and septic shock increase with RA levels.

The association between serum albumin and long length of stay of patients with acute heart failure: A retrospective study based on the MIMIC-IV database. PLoS One 2023; 18:e0282289. [PMID: 36827460 PMCID: PMC9956661 DOI: 10.1371/journal.pone.0282289] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Accepted: 02/12/2023] [Indexed: 02/26/2023] Open
Abstract
BACKGROUND The purpose of this article is to assess the relationship between serum albumin level and long length of stay (LOS) of inpatients with acute heart failure (AHF) in the intensive care unit (ICU). METHODS We retrospectively analyzed data of 2280 patients with AHF from the medical information mart for intensive care IV (the MIMIC-IV) database. Multivariate logistic regression was performed to evaluate the association between serum albumin and long LOS, and the development of the predictive model was based on independent predictors of long LOS. RESULTS According to the statistical results, A negative linear relationship was presented between albumin and long LOS of AHF patients in the ICU (P for trend <0.001), and serum albumin could predict long LOS (AUC 0.649, 95%CI 0.616-0.683, P <0.001). Based on independent predictors, including respiratory failure (OR 1.672, 95%CI 1.289-2.169, P<0.001), WBC (OR 1.046, 95%CI 1.031-1.061, P<0.001), creatinine (OR 1.221, 95%CI 1.098-1.257, P<0.001), glucose (OR 1.010, 95%CI 1.007-1.012, P<0.001), lactic acid (OR 1.269, 95%CI 1.167-1.381, P<0.001), and albumin (OR 0.559, 95%CI 0.450-0.695, P<0.001), identified by multivariable logistic regression analysis, we developed the nomogram to predict the probability of long LOS of AHF patients in the ICU. The nomogram accurately predicted the probability of long LOS (AUC 0.740, 95%CI 0.712-0.768, P<0.001). The calibration suggested the predictive probability was highly consistent with the actual probability of long LOS. Decision curve analysis (DCA) also suggested that the nomogram was applicable in the clinic. CONCLUSION Serum albumin level was negatively associated with LOS among AHF patients. The predictive model based on serum albumin has predictive value for evaluating the length of stay in AHF patients.

Abstract
This review examines the current literature to identify biomarkers of frailty across patients with solid tumors. We conducted the systematic review using preferred reporting items for systematic reviews and meta-analysis guidelines (PRISMA). PubMed, Web of Science, and Embase databases were searched from their inception to December 08, 2021, for reports of biomarkers and frailty. Two reviewers independently screened titles, abstracts, and full-text articles. A quality assessment was conducted using NHLBI Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies, and Quality Assessment of Case-Control Studies. In total, 915 reports were screened, and 14 full-text articles were included in the review. Most studies included breast tumors, were cross-sectional in design, and measured biomarkers at baseline or pre-treatment. Frailty tools varied with Fried Frailty Phenotype and the geriatric assessment most frequently used. Increased inflammatory parameters (i.e., Interleukin-6, Neutrophil Lymphocyte Ratio, Glasgow Prognostic Score-2) were associated with frailty severity. Only six studies were rated as good quality using assessment ratings. Together, the small number of studies and heterogeneity in frailty assessment limited our ability to draw conclusions from the extant literature. Future research is needed to identify potential target biomarkers of frailty in cancer survivors that may aid in early detection and referral.

Abstract
Tumours utilise tryptophan (Trp) and its metabolites to promote their growth and evade host defences. They recruit Trp through up-regulation of Trp transporters, and up-regulate key enzymes of Trp degradation and down-regulate others. Thus, Trp 2,3-dioxygenase (TDO2), indoleamine 2,3-dioxygenase 1 (IDO1), IDO2, N'-formylkynurenine formamidase (FAMID) and Kyn aminotransferase 1 (KAT1) are all up-regulated in many cancer types, whereas Kyn monooxygenase (KMO), kynureninase (KYNU), 2-amino-3-carboxymuconic acid-6-semialdehyde decarboxylase (ACMSD) and quinolinate phosphoribosyltransferase (QPRT) are up-regulated in a few, but down-regulated in many, cancers. This results in accumulation of the aryl hydrocarbon receptor (AhR) ligand kynurenic acid and in depriving the host of NAD+ by blocking its synthesis from quinolinic acid. The host loses more NAD+ by up-regulation of the NAD+-consuming poly (ADP-ribose) polymerases (PARPs) and the protein acetylaters SIRTs. The nicotinamide arising from PARP and SIRT activation can be recycled in tumours to NAD+ by the up-regulated key enzymes of the salvage pathway. Up-regulation of the Trp transporters SLC1A5 and SLC7A5 is associated mostly with that of TDO2 = FAMID > KAT1 > IDO2 > IDO1. Tumours down-regulate enzymes of serotonin synthesis, thereby removing competition for Trp from the serotonin pathway. Strategies for combating tumoral immune escape could involve inhibition of Trp transport into tumours, inhibition of TDO and IDOs, inhibition of FAMID, inhibition of KAT and KYNU, inhibition of NMPRT and NMNAT, inhibition of the AhR, IL-4I1, PARPs and SIRTs, and by decreasing plasma free Trp availability to tumours by albumin infusion or antilipolytic agents and inhibition of glucocorticoid induction of TDO by glucocorticoid antagonism.

Abstract
BACKGROUND The symptoms of adrenal insufficiency (AI) overlap with the common effects of advanced cancer and chemotherapy. Considering that AI may negatively affect the overall prognosis of cancer patients if not diagnosed in a timely manner, we analyzed the incidence, risk factors, and predictive methods of AI in cancer patients. METHODS We retrospectively analyzed the medical records of 184 adult patients with malignancy who underwent a rapid adrenocorticotrophic hormone stimulation test in the medical hospitalist units of a tertiary hospital. Their baseline characteristics and clinical features were evaluated, and the risk factors for AI were identified using logistic regression analysis. RESULTS Of the study patients, 65 (35%) were diagnosed with AI, in whom general weakness (63%) was the most common symptom. Multivariate logistic regression showed that eosinophilia (adjusted odds ratio [aOR], 4.28; 95% confidence interval [CI], 1.10-16.63; P = 0.036), history of steroid use (aOR, 2.37; 95% CI, 1.10-5.15; P = 0.028), and history of megestrol acetate use (aOR, 2.71; 95% CI, 1.38-5.33; P = 0.004) were associated with AI. Baseline cortisol levels of 6.2 μg/dL and 12.85 μg/dL showed a specificity of 95.0% and 95.4% for AI diagnosis, respectively. CONCLUSION AI was found in about one-third of patients with cancer who showed general symptoms that may be easily masked by cancer or chemotherapy, suggesting that clinical suspicion of AI is important while treating cancer patients. History of corticosteroids or megestrol acetate were risk factors for AI and eosinophilia was a pre-test predictor of AI. Baseline cortisol level appears to be a useful adjunct marker for AI.

Abstract
PURPOSE To identify risk factors associated with the development of acute respiratory distress syndrome (ARDS) in infants with early onset sepsis (EOS) and to describe the clinical features. METHODS A retrospective study was conducted at the Children's Hospital of Chongqing Medical University between January 2000 and October 2020. The infants were divided into ARDS and non-ARDS groups. Clinical characteristics and risk factors were compared between the two groups. RESULTS Two hundred fifty infants (58 with ARDS) were included. Smaller gestational age, lower birth weight (LBW), lower serum albumin level, a higher rate of preterm birth, premature rupture of membranes, antenatal steroid exposure, and lower Apgar score were associated with an increased development of ARDS by univariate analysis (P < 0.05). LBW (β = -0.001, P = 0.000, OR: 0.999, 95% CI: 0.998-0.999) and low serum albumin levels (β = -0.063, P = 0.022, OR: 0.939, 95% CI: 0.889-0.991) were identified as independent risk factors for the development of ARDS by logistic regression analysis. A higher frequency of complications, including persistent pulmonary hypertension, intraventricular hemorrhage, pulmonary hemorrhage, septic shock, and bronchopulmonary dysplasia, was found in the ARDS group (P < 0.05). The rate of mortality was higher for those in the ARDS group than for those in the non-ARDS group (46.6% vs. 15.6%, χ2 = 24.205, P = 0.000). CONCLUSION Acute respiratory distress syndrome (ARDS) in EOS could lead to a higher frequency of complications and mortality. The risk factors for the development of ARDS were LBW and low serum albumin levels.

Abstract
Albumin, as the most abundant plasma protein, plays an integral role in the transport of a variety of exogenous and endogenous ligands in the bloodstream and extravascular spaces. For exogenous drugs, especially chemotherapeutic drugs, binding to and being delivered by albumin can significantly affect their efficacy. Meanwhile, albumin can also bind to many endogenous ligands, such as fatty acids, with important physiological significance that can affect tumor proliferation and metabolism. In this review, we summarize how albumin with unique properties affects chemotherapeutic drugs efficacy from the aspects of drug outcome in blood, toxicity, tumor accumulation and direct or indirect interactions with fatty acids, plus application of albumin-based carriers for anti-tumor drug delivery.

Abstract
A common problem in many cancers is the resistance of some patients to common drugs or relapse. Hypoalbuminemia has been reported in some of resistant cancer patients.This article evaluates the usefulness of albumin in the treatment of drug-resistant cancers with hypoalbuminemia based on available evidences.Rapid metabolism and drug excretion from the body is one of the causes of drug resistance. Albumin is the major plasma protein to which almost all drugs are bound. There is some evidence that increasing drug binding to albumin has beneficial effects on drug efficacy in some cancers and cancer cells. On the other hand, some reports have shown that cancer cells can use albumin as the energy and amino acid source.We have hypothesized that in this particular group of cancers, adding albumin to a treatment regimen could have a beneficial effect on drug efficacy and dosage. In fact, excess albumin can prevent rapid metabolism of drug by increasing the fraction of albumin-bound drug, and can increase drug delivery to cancer cells due to the absorption of drug-albumin complex by cancer cells.

Abstract
Albumin plays a key role in the critically ill patient acting as a prognostic marker and as a therapy in the form of human albumin solutions. However, the use of human albumin solution has varied over time with notable differences between health systems. Whilst its use is widely accepted for some clinical indications, its role has not always been clear in the critically ill and has been found to be harmful in some cohorts. Numerous studies have showed conflicting results and critical care clinicians have not always been guided by robust evidence. Nonetheless, at present the use of human albumin solution appears to be increasing again in the United Kingdom. Below, we discuss the latest evidence base for its use in critically ill patients.

Abstract
BACKGROUND Hypoalbuminemia is commonly observed in cancer patients. Given the pharmacokinetic interactions between serum proteins and protein bound medications, administration of highly protein bound targeted oral oncolytic drugs may result in elevated unbound drug levels and decreased tolerability in those with hypoalbuminemia. OBJECTIVE To describe the impact of hypoalbuminemia on oral oncolytic drug tolerability. METHODS A retrospective study was conducted of adult patients receiving treatment with targeted oral oncolytic drugs with ≥95% protein binding. The primary end point of this study was to compare time to discontinuation resulting from documented toxicity in those with and without hypoalbuminemia. RESULTS The study included 143 patients receiving 16 targeted oral oncolytic drugs (42% with hypoalbuminemia, 58% without hypoalbuminemia). Adverse events were common, with similar incidence among patients with and without hypoalbuminemia (73% vs 76%, respectively; P = 0.727). Median time to therapy discontinuation resulting from documented toxicity was significantly shorter in those with hypoalbuminemia (22 months vs not reached; P = 0.003). Cox regression demonstrated that hypoalbuminemia was the only significant risk factor for shorter time to discontinuation resulting from documented adverse effects (hazard ratio = 3.0; 95% CI = 1.15-8.0; P = 0.025). CONCLUSION AND RELEVANCE This represents the first report of the impact of hypoalbuminemia on tolerability of highly protein bound oral oncolytic drugs, demonstrating that patients with hypoalbuminemia may be at increased risk for early discontinuation resulting from toxicity. Given the importance of maintaining dose intensity in patients receiving oncolytic therapy, albumin levels should be monitored throughout treatment and supportive care maximized in those developing hypoalbuminemia.

Abstract
AIM The aim of this study is to assess the association between admission serum albumin and short- and long-term mortality in all hospitalized patients. DESIGN A single-center cohort study. METHODS A retrospective cohort of all adult hospitalized patients at a tertiary referral hospital between January 2009 and December 2013 were analysed. Admission serum albumin was stratified into six groups: ≤2.4, 2.5-2.9, 3.0-3.4, 3.5-3.9, 4.0-4.4 and ≥4.5 g/dl. The outcomes of interest were in-hospital mortality, length of hospital stay and 1-year mortality. Serum albumin of 4-4.4 g/dl was selected as a reference group for outcome comparison. RESULTS A total of 14 075 patients were studied. Admission serum albumin of ≥4.5 g/dl had the lowest in-hospital and 1-year mortality with progressively increased in-hospital mortality observed with decreased admission serum albumin. In adjusted analysis, compared with serum albumin of 4.0-4.4 g/dl, serum albumin of ≤2.4, 2.5-2.9, 3.0-3.4 and 3.5-3.9 were significantly associated with increased in-hospital and 1-year mortality. In contrast, serum albumin of ≥4.5 g/dl was significantly associated with lower 1-year mortality but not in-hospital mortality. Admission serum albumin <4.0 g/dl was significantly associated with a prolonged hospital stay, while admission serum albumin of ≥4.5 g/dl was significantly associated with shorter hospital stay, compared with serum albumin of 4.0-4.4 g/dl. CONCLUSION Low albumin level at admission was progressively associated with increased short- and long-term mortality in all hospitalized patients even when albumin level was considered in normal range.

Abstract
The albumin-bilirubin (ALBI) grade has been validated as a significant predictor for hepatocellular carcinoma (HCC). However, there is little information about the impact of postoperative ALBI grade in patients with HCC who are undergoing liver resection. We enrolled 525 HCC patients who received primary resection from April 2001 to March 2017. The impact of the pre- and post-operative ALBI grades on overall survival (OS) and recurrence-free survival (RFS) were analyzed by multivariate analysis. During the follow-up period (mean, 65 months), 253 (48.1%) patients experienced recurrence, and 85 (16.2%) patients died. Multivariate analysis revealed that diabetes mellitus (DM) (p = 0.011), alpha-fetoprotein levels (AFP) (p < 0.001), low platelet count (p = 0.008), liver cirrhosis (p < 0.001), and the first year of ALBI grade after resection (p < 0.001) were independent predictors for RFS. Additionally, old age (p = 0.006), DM (p = 0.002), AFP (p = 0.027), and ALBI grade at the first year after resection (p < 0.001) were independent risk factors for poor liver-related survival. Patients with post-operative ALBI grades II/III had older age (p = 0.019), hypoalbuminemia (p = 0.038), DM (p = 0.043), and high stages of pTNM (p = 0.021). The post-operative ALBI grade is better for predicting the outcomes in HCC patients after curative hepatectomy than the pre-operative ALBI grade.

Abstract
Background There is no evidence to suggest the predictive power of neutrophil percentage-to-albumin ratio (NPAR) in patients with acute kidney injury (AKI). We hypothesized that NPAR would correlate with all-cause mortality in critically ill patients with AKI. Methods From the MIMIC-III V1.4 database, we extracted demographics, vital signs, comorbidities, laboratory tests, and other clinical data. The clinical endpoints were 30-, 90- and 365-day all-cause mortality in critically ill patients with AKI. Cox proportional hazards models were used to evaluate the prognostic values of NPAR, and subgroup analyses were performed to measure mortality across various subgroups. Results A total of 7,481 eligible subjects were enrolled. In multivariate analysis, after adjustments for age, ethnicity, gender, and other confounding factors, higher NPARs were associated with an increased risk of 30-, 90- and 365-day all-cause mortality in critically ill patients with AKI (tertile 3 versus tertile 1: adjusted HR, 95% CI: 1.48, 1.30–1.69; 1.47, 1.31–1.66; 1.46, 1.32–1.62, respectively; P trend <0.01). A similar trend was observed in the NPAR group division by quintiles. Subgroup analysis revealed no significant interactions in most strata. Conclusions Increased NPAR correlates with increased risk of all-cause mortality in critically ill patients with AKI.

Abstract
Serum albumin is a marker of nutritional and frailty status. This study aimed to assess the association between serum albumin at the time of admission and the risk of acute respiratory failure (ARF) in hospitalized patientsThis cohort study, performed at a tertiary referral hospital, included all hospitalized adult patients from January 2009 to December 2013 who had serum albumin measurement and were not on mechanical ventilation within 24 hours of hospital admission. Serum albumin was stratified into 2.4, 2.5 to 2.9, 3.0 to 3.4, 3.5 to 3.9, 4.0 to 4.4, and ≥4.5 g/dL. Multivariate logistic regression analysis was performed to obtain adjusted odds ratio (OR) of risk of ARF requiring mechanical ventilation based on various admission serum albumin levels.Of 12,719 patients, ARF requiring mechanical ventilation occurred in 1128 (8.9%) during hospitalization. Hypoalbuminemia was associated with increased risk of ARF, in particular when serum albumin was ≤2.4 g/dL. Compared with serum albumin of 4.0-4.4 g/dL, serum albumin ≤2.4 g/dL at admission was associated with 2.38-time higher odds of ARF during hospitalization (OR 2.38, 95% confidence interval [CI] 1.84-3.07). In contrast, elevated serum albumin ≥4.5 g/dL was associated with lower odds of ARF (OR 0.68, 95% CI 0.48-0.97).Admission serum albumin level lower than 3.5 g/dL was associated with a higher risk of ARF requiring mechanical ventilation, whereas elevated serum albumin level at least 4.5 g/dL was associated with a lower risk of ARF. Therefore, admission albumin level at admission might be useful in the prediction of ARF during hospitalization.

Abstract
The aim of this study was to identify potential factors associated with insufficient/toxic voriconazole trough concentrations (VTCs) in patients in order to screen the high-risk population. A total of 119 VTCs were obtained from 67 patients. Multivariate regression analysis suggested that insufficient VTCs (<1.0 mg/L) were significantly associated with younger age and underlying hematological malignancy, and toxic VTCs (>5.5 mg/L) were significantly associated with lower serum albumin (ALB) level. Receiver operating characteristic curve analysis indicated that patients whose age < 47 years were the high-risk population of insufficient VTCs, and patients whose ALB <27 g/L were the high-risk population of toxic VTCs. Younger age and underlying hematological malignancy were significant predictors of insufficient VTCs, and lower ALB level was found to be a significant predictor of toxic VTCs. Therefore, we recommend to increase the monitoring on these high-risk population to avoid treatment failure and to prevent toxic adverse events.

Abstract
Cell-free and concentrated ascites reinfusion therapy (CART) is frequently used to treat refractory ascites in Japan. However, its efficacy remains unclear. This controlled cohort study verified the serum albumin elevating effect of CART by comparisons with simple paracentesis. Ascites patients receiving CART (N = 88) or paracentesis (N = 108) at our hospital were assessed for the primary outcome of change in serum albumin level within 3 days before and after treatment. A significantly larger volume of ascites was drained in the CART group. The change in serum albumin level was +0.08 ± 0.25 g/dL in the CART group and −0.10 ± 0.30 g/dL in the paracentesis group (P < 0.001). The CART – paracentesis difference was +0.26 g/dL (95%CI +0.18 to +0.33, P < 0.001) after adjusting for potential confounders by multivariate analysis. The adjusted difference increased with drainage volume. In the CART group, serum total protein, dietary intake, and urine volume were significantly increased, while hemoglobin and body weight was significantly decreased, versus paracentesis. More frequent adverse events, particularly fever, were recorded for CART, although the period until re-drainage was significantly longer. This study is the first demonstrating that CART can significantly increase serum albumin level as compared with simple paracentesis. CART represents a useful strategy to manage patients requiring ascites drainage.

Abstract
The aim of the present study was to investigate the clinicopathological features and prognostic factors associated with pre- and postoperative serum albumin levels in patients with curatively resected pancreatic ductal adenocarcinoma (PDAC). To achieve this, the data of patients who underwent pancreatectomy for PDAC between January 1995 and March 2016 were retrospectively reviewed, and the pre- and postoperative serum albumin levels at postoperative months (POMs) 3, 6, and 12 were evaluated. The serum albumin recovery rate was also investigated. A total of 196 patients were enrolled in the present study. In the multivariate Cox regression analysis, lymph node metastasis [hazard ratio (HR): 1.65; P=0.022], serum albumin level at POM 12 (≥3.9 g/dl; HR: 0.60; P=0.017), and serum albumin recovery rate at POM 12 (≥1.00; HR: 0.60; P=0.017) were independent prognostic factors for disease-free survival. Lymph node metastasis (HR: 1.79; P=0.013) and serum albumin level at POM 12 (≥3.9 g/dl) (HR: 0.60; P=0.033) were independent prognostic factors for overall survival. These results indicated that the postoperative level and recovery rate of serum albumin are potential biomarkers for predicting the prognosis of patients with curatively resected PDAC. However, further studies are required in order to investigate the survival benefit of increasing postoperative serum albumin levels in these patients.

Abstract
AIMS To determine the relationship between trends in admission serum albumin and long-term mortality in medical patients with hospital readmission. MATERIALS AND METHODS We used a cohort of patients admitted to five departments of internal medicine during 3 years. Survival analysis was performed based on mean admission serum albumin levels and trends in albumin values from recurrent admissions. RESULTS A total of 5396 patients had 16 640 admissions (readmission cohort), another 9422 patients were admitted only once (single admission cohort). Readmitted patients with low mean albumin were older, predominantly females and had higher comorbidity index than patients with normal mean albumin. The 6-month all-cause mortality rate of the normal and low mean albumin groups was 5.2% and 24.2%, respectively (P < 0.001). Survival analysis showed that patients with persistently normal albumin levels had the highest survival rates at 6 months (97.7%), compared with patients who had hypoalbuminemia at index admission but normalised their albumin levels in subsequent admissions (92%), patients with declining albumin trends (85.6%) and patients with persistently low albumin levels (68.9%) (P < 0.0001). CONCLUSIONS Serum albumin is strongly associated with long-term mortality in readmitted medical patients. Persistent hypoalbuminemia during recurrent admissions is associated with increased risk of long-term mortality.

Li J, Ma J, Wagar EA, Liang D, Meng QH. A rapid ultra-performance LC-MS/MS assay for determination of serum unbound fraction of voriconazole in cancer patients. Clin Chim Acta 2018; 486:36-41. [PMID: 30016626 DOI: 10.1016/j.cca.2018.07.022] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2018] [Revised: 07/09/2018] [Accepted: 07/11/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND Voriconazole (VOR), an antifungal agent, is clinically monitored to guide therapeutic dosing and avoid toxicity. It is believed that measurement of serum unbound VOR provides more accurate information, especially in hypoalbuminemia patients. We developed and validated an accurate, simple and fast test with ultrafiltration and ultra-performance liquid chromatography (UPLC)-tandem mass spectrometry (MS/MS) to measure unbound VOR in human serum. METHODS The Agilent UPLC system coupled with a SCIEX QTRAP4000 MS with a positive ionization mode was developed and validated for VOR analysis. RESULTS A good linearity was demonstrated from 0.02 to 2.5 μg/ml for unbound VOR (r2 = 0.9969). The within-run and between-run accuracy and precision was <5% and < 6%. The levels of total VOR were well correlated with reference laboratory results. Serum unbound VOR levels were correlated with the total VOR levels (r = 0.78, p < 0.0001). There was a reverse correlation between unbound VOR fractions and plasma albumin levels (p < 0.05). In hypoalbuminemia patients, the unbound VOR levels were increased to a higher degree than total VOR. CONCLUSION This assay is suitable for monitoring both unbound and bound VOR in cancer patients especially in those with hypoalbuminemia in clinical laboratories. Measurement of unbound VOR offers a better approach in prediction of VOR toxicity.

U-shape association of serum albumin level and acute kidney injury risk in hospitalized patients. PLoS One 2018; 13:e0199153. [PMID: 29927987 PMCID: PMC6013099 DOI: 10.1371/journal.pone.0199153] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2017] [Accepted: 06/03/2018] [Indexed: 12/31/2022] Open
Abstract
Background While an association between hypoalbuminemia and increased risk of acute kidney injury (AKI) is well-established, the risk of AKI development and its severity among patients with elevated serum albumin is unclear. The aim of this study was to evaluate the risk of AKI in hospitalized patients stratified by various admission serum albumin levels. Methods This single-center retrospective study was conducted at a tertiary referral hospital. All adult hospitalized patients who had admission albumin levels available between January 2009 and December 2013 were enrolled. Admission albumin was categorized based on its distribution into six groups (≤2.4, 2.5–2.9, 3.0–3.4, 3.5–3.9, 4.0–4.4, and ≥4.5 mg/dL). The primary outcome was the incidence of hospital-acquired AKI (HAKI). Logistic regression analysis was performed to obtain the odds ratio of AKI for various admission albumin strata using the albumin 3.5 to 3.9 mg/dL (lowest incidence of AKI) as the reference group. Results Of the total 9,552 studied patients, HAKI occurred in 1,556 (16.3%) patients. The incidence of HAKI among patients with admission albumin ≤2.4, 2.5–2.9, 3.0–3.4, 3.5–3.9, 4.0–4.4, and ≥4.5 mg/dL was 18.3%, 14.3%, 15.5%, 14.2%, 16.7%, and 26.0%, respectively. After adjusting for potential confounders, admission serum albumin levels ≤2.4 and ≥4.5 mg/dL were associated with an increased risk of HAKI with odds ratios of 1.52 (95% CI 1.18–1.94) and 2.16 (95% CI 1.74–2.69), respectively. While stage 1 HAKI was significantly more frequent among patients with admission albumin ≥4.5 mg/dL (23.0% vs. 11.6%, P<0.001), incidence of stage 3 HAKI was higher in those with albumin ≤2.4 mg/dL (2.8% vs 0.3%, P<0.001). Conclusion Admission serum albumin levels ≤2.4 and ≥4.5 mg/dL were associated with an increased risk for HAKI. Patients with admission albumin ≥4.5 mg/dL had HAKI with a lower intensity when compared with those who had admission albumin levels ≤2.4 mg/dL.

Badawy AAB. Targeting tryptophan availability to tumors: the answer to immune escape? Immunol Cell Biol 2018; 96:1026-1034. [PMID: 29888434 DOI: 10.1111/imcb.12168] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2018] [Revised: 05/12/2018] [Accepted: 05/13/2018] [Indexed: 12/18/2022]
Abstract
Tumoral immune escape is an obstacle to successful cancer therapy. Tryptophan (Trp) metabolites along the kynurenine pathway induce immunosuppression involving apoptosis of effector immune cells, which tumors use to escape an immune response. Production of these metabolites is initiated by indoleamine 2,3-dioxygenase (IDO1). IDO1 inhibitors, however, do not always overcome the immune escape and another enzyme expressed in tumors, Trp 2,3-dioxygenase (TDO2), has been suggested as the reason. However, without Trp, tumors cannot achieve an immune escape through either enzyme. Trp is therefore key to immune escape. In this perspective paper, Trp availability to tumors will be considered and strategies limiting it proposed. One major determinant of Trp availability is the large increase in plasma free (non-albumin-bound) Trp in cancer patients, caused by the low albumin and the high non-esterified fatty acid (NEFA) concentrations in plasma. Albumin infusions, antilipolytic therapy or both could be used, if indicated, as adjuncts to immunotherapy and other therapies. Inhibition of amino acid uptake by tumors is another strategy and α-methyl-DL-tryptophan or other potential inhibitors could fulfill this role. Glucocorticoid receptor antagonists may have a role in preventing glucocorticoid induction of TDO in host liver and tumors expressing it and in undermining the permissive effect of glucocorticoids on IDO1 induction by cytokines. Nicotinamide may be a promising TDO2 inhibitor lacking disadvantages of current inhibitors. Establishing the Trp disposition status of cancer patients and in various tumor types may provide the information necessary to formulate tailored therapeutic approaches to cancer immunotherapy that can also undermine tumoral immune escape.

Abstract
AIM Medical comorbidities are a major cause of death among patients with mental illness. The purpose of this study was to clarify the risk factors for mortality among psychiatric patients with medical comorbidities. METHODS We retrospectively reviewed the clinical files of patients transferred to Tokyo Metropolitan Matsuzawa Hospital from a psychiatric hospital to treat medical comorbidities during the 3-year period from January 2014 to December 2016. We analyzed the clinical differences between the expired and alive patients. RESULTS Of the 287 patients included, 29 (10.1%) had expired at the time of hospital discharge, while 258 (89.9%) were living. A multivariable analysis to determine the prognostic factors related to mortality from medical comorbidities showed that body mass index <18.5 had the highest odds ratio among the predictive factors (5.1; 95% confidence interval, 1.5-17.1; P < 0.05), followed by a serum albumin level < 3.0 mg/dL (3.0; 95% confidence interval, 1.1-8.1; P < 0.05). CONCLUSION We found that underweight and hypoalbuminemia were risk factors for mortality among psychiatric patients with medical comorbidities. Physicians at psychiatric hospitals should consider transferring patients with medical comorbidities to a general medical hospital in the presence of underweight and/or hypoalbuminemia.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) continues to have the poorest prognosis of all gastrointestinal malignancies, even after the tumor has been completely resected. However, only a proportion of patients achieve 5-year survival after resection. The factors predictive of achieving 5-year survival remain unclear. The aim of this study was to investigate the pre- and postoperative clinicopathological characteristics of PDAC patients with a >5-year survival after curative resection. We retrospectively reviewed patients who underwent pancreatectomy for PDAC between January 1995 and December 2011. Logistic regression analysis was performed to determine the predictive factors for 5-year survival. One hundred and fifty-one patients were enrolled, including 38 patients with 5-year survival (actual 5-year survival rate, 25.2%). The independent preoperative factors predictive of achieving 5-year survival included serum albumin levels (odds ratio [OR]: 5.06, 95.0% confidence interval [CI]: 1.49-17.19; P = 0.009) and neoadjuvant chemoradiotherapy (OR: 3.02, 95.0% CI: 1.00-9.08; P = 0.049). Venous infiltration (OR: 2.99, 95.0% CI: 1.09-8.25; P = 0.034), liver recurrence (OR: 0.17, 95.0% CI: 0.04-0.69; P = 0.013), and perioperative portal vein infusion chemotherapy (OR: 3.06, 95.0% CI: 1.09-8.25; P = 0.028) were found to be independent postoperative predictive factors for achieving 5-year survival. Serum albumin levels could be a biomarker for predicting the prognosis of PDAC patients after curative resection. Liver recurrence and perioperative portal vein infusion chemotherapy were independent postoperative factors, suggesting that perioperative portal vein infusion chemotherapy could be promising for improving the survival rate of PDAC patients after curative resection.

Abstract
BACKGROUND The association between hypoalbuminaemia and a new diagnosis of cancer is as yet unknown. OBJECTIVE This study aimed to assess whether unexplained hypoalbuminaemia was associated with an increased risk of subsequent new cancer diagnosis within the next 12 months. METHODS A cohort study was performed using a large UK database of adult primary care patients. Patients with a serum albumin test, either low or normal, were followed for 12 months for a new diagnosis of non-skin cancer. Logistic regression was used to assess for relationships between hypoalbuminaemia and cancer diagnoses. RESULTS A total of 100 122 participants had at least one albumin test result. Of these, 5753 (5.75%) had a result <35g/l, of whom 1634 developed cancer within 12 months. Of the 94 116 patients with normal albumin values, 13 906 developed cancer. Hypoalbuminaemia was associated with an increased risk of subsequent cancer diagnosis within 12 months (odds ratio [OR]: 2.29; 95% confidence interval [CI]: 2.15-2.43). This association was smaller in magnitude after controlling for other conditions known to affect albumin levels (OR: 1.29; 95% CI: 1.12-1.49). CONCLUSIONS Low albumin levels were associated with an increased risk of cancer. This finding needs to be confirmed in other primary care populations.

Abstract
BACKGROUND Colorectal surgery carries a significant mortality risk, with reported rates of 1-6% for elective surgery and up to 22% in the emergency setting. Both clinicians and patients will benefit from being able to predict the likelihood of death before surgery. Recently, we have described and validated two risk stratification models for colorectal surgery, the Barwon Health 2012 and Association Française de Chirurgie models. However, these models are not suitable for assessment at patient's bedside. The purpose of this study is to develop a simplified preoperative model capable of predicting mortality following colorectal surgery. METHODS The new model is termed Colorectal preOperative Surgical Score (CrOSS). The development and internal validation of CrOSS was performed using a prospectively maintained colorectal database. External validation was performed using retrospective data. Univariate and multivariate analyses were performed in model development. Calibration and discrimination were used for model validation. RESULTS There were 474 and 389 consecutive colorectal surgeries at Geelong Hospital and Western Hospital. Overall mortality rates were 5.16% and 1.03%, respectively. Significant predictors for mortality were as follows: age ≥70, urgent operation, albumin ≤30 g/L and congestive heart failure (receiver operating characteristic (ROC) = 0.870, calibration P-value = 0.937). The predicted risk of mortality was stratified according to the risk profile of 0.39-66.51%. When validated externally, CrOSS predicted mortality accurately (ROC = 0.847, calibration P-value = 0.199). CONCLUSIONS A robust and simple preoperative model has been created to risk-stratify patients for colorectal surgery. This was successfully validated at another tertiary hospital.

Abstract
Introduction The mortality rate of perforated peptic ulcer is still high particularly for aged patients and all the existing scoring systems to predict mortality are complicated or based on history taking which is not always reliable for elderly patients. This study’s aim was to develop an easy and applicable scoring system to predict mortality based on hospital admission data. Methods Total 227 patients operated for perforated peptic ulcer in two centers were included. All data that may be potential predictors with respect to hospital mortality were retrospectively analyzed. Results The mortality and morbidity rates were 10.1% and 24.2%, respectively. Multivariated analysis pointed out three parameters corresponding 1 point for each which were age >65 years, albumin ≤1,5 g/dl and BUN >45 mg/dl. Its prediction rate was high with 0,931 (95% CI, 0,890 to 0,961) value of AUC. The hospital mortality rates for none, one, two and three positive results were zero, 7.1%, 34.4% and 88.9%, respectively. Conclusion Because the new system consists only age and routinely measured two simple laboratory tests (albumin and BUN), its application is easy and prediction power is satisfactory. Verification of this new scoring system is required by large scale multicenter studies.

Abstract
Objective Emergency patients with hypoalbuminemia are known to have increased mortality. No previous studies have, however, assessed the predictive value of low albumin on mortality in unselected acutely admitted medical patients. We aimed at assessing the predictive power of hypoalbuminemia on 30-day all-cause mortality in a cohort of acutely admitted medical patients. Methods We included all acutely admitted adult medical patients from the medical admission unit at a regional teaching hospital in Denmark. Data on mortality was extracted from the Danish Civil Register to ensure complete follow-up. Patients were divided into three groups according to their plasma albumin levels (0–34, 35–44 and ≥45 g/L) and mortality was identified for each group using Kaplan-Meier survival plot. Discriminatory power (ability to discriminate patients at increased risk of mortality) and calibration (precision of predictions) for hypoalbuminemia was determined. Results We included 5,894 patients and albumin was available in 5,451 (92.5%). A total of 332 (5.6%) patients died within 30 days of admission. Median plasma albumin was 40 g/L (IQR 37–43). Crude 30-day mortality in patients with low albumin was 16.3% compared to 4.3% among patients with normal albumin (p<0.0001). Patients with low albumin were older and admitted for a longer period of time than patients with a normal albumin, while patients with high albumin had a lower 30-day mortality, were younger and were admitted for a shorter period. Multivariable logistic regression analyses confirmed the association of hypoalbuminemia with mortality (OR: 1.95 (95% CI: 1.31–2.90)). Discriminatory power was good (AUROC 0.73 (95% CI, 0.70–0.77)) and calibration acceptable. Conclusion We found hypoalbuminemia to be associated with 30-day all-cause mortality in acutely admitted medical patients. Used as predictive tool for mortality, plasma albumin had acceptable discriminatory power and good calibration.

Abstract
Albumin solutions have been used worldwide for the treatment of critically ill patients since they became commercially available in the 1940s. However, their use has become the subject of criticism and debate in more recent years. Importantly, all fluid solutions have potential benefits and drawbacks. Large multicenter randomized studies have provided valuable data regarding the safety of albumin solutions, and have begun to clarify which groups of patients are most likely to benefit from their use. However, many questions remain related to where exactly albumin fits within our fluid choices. Here, we briefly summarize some of the physiology and history of albumin use in intensive care before offering some evidence-based guidance for albumin use in critically ill patients.

Abstract
Controversy reigns as to how protein binding changes alter the time course of unbound drug concentrations in patients. Given that the unbound concentration is responsible for drug efficacy and potential drug toxicity, this area is of significant interest to clinicians and academics worldwide. The present uncertainty means that many questions relating to this area exist, including "How important is protein binding?", "Is protein binding always constant?", "Do pH and temperature changes alter binding?" and "How do protein binding changes affect dosing requirements?". In this paper, we seek to address these questions and consider the data associated with altered pharmacokinetics in the presence of changes in protein binding and the clinical consequences that these may have on therapy, using examples from the critical care area. The published literature consistently indicates that a change in the protein binding and unbound concentrations of some drugs are common in certain specific patient groups such as the critically ill. Changes in pharmacokinetic parameters, including clearance and apparent volume of distribution (V(d)), may be dramatic. Drugs with high protein binding, high intrinsic clearance (e.g. clearance by glomerular filtration) and where dosing is not titrated to effect are most likely to be affected in a clinical context. Drugs such as highly protein bound antibacterials with multiple half-lives within a dosing interval and that have some level of renal clearance, such as ertapenem, teicoplanin, ceftriaxone and flucloxacillin, are commonly affected. In response to these challenges, clinicians need to adapt dosing regimens rationally based on the pharmacokinetic/pharmacodynamic characteristics of the drug. We propose that further pharmacokinetic modelling-based research is required to enable the design of robust dosing regimens for drugs affected by altered protein binding.

Abstract
This review introduces the pathology of aminoglycoside antibiotic and the cisplatin chemotherapy classes of drugs, discusses oxidative stress in the inner ear as a primary trigger for cell damage, and delineates the ensuing cell death pathways. Among potentially ototoxic (damaging the inner ear) therapeutics, the platinum-based anticancer drugs and the aminoglycoside antibiotics are of critical clinical importance. Both drugs cause sensorineural hearing loss in patients, a side effect that can be reproduced in experimental animals. Hearing loss is reflected primarily in damage to outer hair cells, beginning in the basal turn of the cochlea. In addition, aminoglycosides might affect the vestibular system while cisplatin seems to have a much lower likelihood to do so. Finally, based on an understanding the mechanisms of ototoxicity pharmaceutical ways of protection of the cochlea are presented.

Abstract
CONTEXT Low albumin levels have been associated with increased mortality, but few studies have looked at the mortality rates of patients with very low albumin levels. OBJECTIVES The objective of this study was to determine the in-hospital mortality rates for patients older than 60 years with albumin levels <2.0 g/dL. METHODS This was a retrospective study of 543 consecutive patients older than the age of 60 who had an albumin level <2.0 g/dL while admitted to Summa Akron City Hospital between July and November 2008. Data were obtained from hospital databases. Mortality rates were calculated for each albumin level and compared with the overall inpatient mortality for patients older than 60 years. Rates of discharge to home were calculated by albumin level. Cross-tabulations and correlations were conducted to determine the association between albumin level and mortality, and to assess the independent effects of total parenteral nutrition, dialysis, cancer, and end-stage renal disease. RESULTS Patients with albumin levels between 1.0 and 1.4 had a 41% in-hospital mortality rate, with only 16% of the patients being discharged to home. Patients with albumin levels between 1.5 and 1.9 had a 21% mortality rate, with 33% of patients discharged to home. Overall hospital mortality for patients older than 60 years was 6% during the study period. Total parenteral nutrition, cancer, dialysis, and end-stage renal disease were not independent risk factors for mortality in this study. CONCLUSION An albumin level is readily obtained across all areas of the hospital and provides a simple and useful aid in identifying patients at high risk of a poor hospital outcome.

Abstract
Purpose This study assessed outcomes of individuals with advanced cancer who required admission to an intensive care unit (ICU) after referral for an early clinical trial because they did not respond to conventional therapy. Patients and Methods Outcome analyses were conducted for 212 consecutive patients admitted to The University of Texas MD Anderson Cancer Center ICU after being seen in the phase I clinic starting on May 1, 2007. All data were obtained by a review of electronic medical records of patients. Results The median survival of 212 patients with advanced cancer referred to phase I care after the initial ICU admission was 3.2 weeks (95% CI, 2.5 to 4.9 weeks). Patients who underwent cardiopulmonary resuscitation (CPR) succumbed within a median survival of 1 day (75% and 25% estimated survival of 1 and 3 days, respectively). Patients admitted for a postsurgical intervention did better than patients admitted for a nonsurgical intervention (median survival, 21.5 versus 2.1 weeks; P < .0001). The multivariate analysis revealed that a nonsurgical intervention, hypoalbuminemia, and higher Acute Physiology and Chronic Health Evaluation II scores were associated with poor overall survival. Conclusion The outcome of patients in a phase I clinic after initial ICU admission was poor, particularly when admission was for a nonsurgical intervention and/or when CPR was needed.
