Dynamic monitoring of neutrophil/lymphocyte ratio, APACHE II score, and SOFA score predict prognosis and drug resistance in patients with Acinetobacter baumannii-calcoaceticus complex bloodstream infection: a single-center retrospective study. Front Microbiol 2024; 15:1296059. [PMID: 38322313 PMCID: PMC10844563 DOI: 10.3389/fmicb.2024.1296059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 01/03/2024] [Indexed: 02/08/2024] Open
Abstract
Objective This study aimed to evaluate the clinical value of dynamic monitoring of neutrophil/lymphocyte ratio (NLR), APACHE II (Acute Physiology and Chronic Health Evaluation II) score, and Sequential Organ Failure Assessment (SOFA) score in predicting 28-day prognosis and drug resistance in patients with bloodstream infection with Acinetobacter baumannii-calcoaceticus complex (Abc complex). Patients and methods In this research, individuals admitted to Tianjin Medical University General Hospital from January 2017 to March 2023 with bloodstream infections and a minimum of one Abc complex positive blood culture were chosen. The risk factors for the 28-day prognosis and drug resistance were analyzed using logistic regression. The NLR, APACHE II score, and SOFA score were evaluated for predicting 28-day prognosis and drug resistance using an ROC curve analysis. The data were analyzed using R Studio to find correlations and conduct survival analysis with the Kaplan-Meier method. Results The final statistical analysis included a total of 129 patients with bloodstream infections caused by Abc complex. Independent risk factors predicting mortality within 28 days were identified as follows: the SOFA score and APACHE II scores at 24 h, and APACHE II scores at 72 h after the onset of blood infection (p < 0.05). NLR, SOFA score, and APACHE II score did not predict drug resistance. Patients with Carbapenem-resistant Acinetobacter baumannii-calcoaceticus complex (CRAB) had shorter survival times than those with carbapenem-sensitive strains (40.77 days vs. 47.65 days, respectively, p = 0.0032). Conclusion The prognosis of Abc complex bloodstream infection is affected by both SOFA and APACHE II scores. Both scoring systems have similar prognostic values at different time points after infection, but for computational convenience, it is recommended to use the SOFA score. NLR exhibits limited effectiveness in predicting mortality within 28 days. Carbapenem-resistant individuals with Abc complex experience significantly reduced survival time. None of the three factors-SOFA score, APACHE II score, and NLR-can early predict the occurrence of CRAB infections effectively.

DDX3X mRNA Expression in T Cells Is Associated with the Severity and Mortality of Septic Patients. DISEASE MARKERS 2022; 2022:5176915. [PMID: 35178128 PMCID: PMC8847006 DOI: 10.1155/2022/5176915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 12/05/2021] [Accepted: 01/19/2022] [Indexed: 11/18/2022]
Abstract
Purpose DDX3X acts as the critical checkpoint of death in stressed cells. The purpose of this study was to evaluate the mRNA expression level of DDX3X in T cells in peripheral blood of patients with sepsis and to explore its correlation with the prognosis of sepsis. Methods Seventy-nine patients with traumatic sepsis were enrolled in this prospective cohort study. Blood samples were collected within 24 hours after the diagnosis of sepsis or septic shock, and the mRNA expression level of DDX3X in T cells was detected by PCR. Results The level of DDX3X mRNA in T cells was significantly increased in septic patients as well as in septic shock patients. The level of DDX3X mRNA was negatively correlated with T cell count and positively correlated with acute physiological and chronic health assessment (APACHE) score and sequential organ failure assessment (SOFA) score (P < 0.01). The area under the curve (AUC) of the receiver operating characteristic (ROC) curve was 0.79 (95% confidence interval (CI), 0.68-0.90). A Cox proportional hazard model identified an association between an increased DDX3X mRNA level (≥1.575) and the risk of 28-day mortality (hazard ratio = 9.540, 95% CI, 2.452-37.108). Conclusions High level of DDX3X mRNA in T cells in sepsis is associated with the severity of sepsis and the mortality of patients with sepsis.

Clinical outcomes of Stenotrophomonas maltophilia infection treated with trimethoprim/sulfamethoxazole, minocycline, or fluoroquinolone monotherapy. Int J Antimicrob Agents 2021; 58:106367. [PMID: 34058337 DOI: 10.1016/j.ijantimicag.2021.106367] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 05/12/2021] [Accepted: 05/19/2021] [Indexed: 11/24/2022]
Abstract
OBJECTIVES The historical treatment of choice for Stenotrophomonas maltophilia infection is trimethoprim/sulfamethoxazole and this is primarily based on preclinical studies. The objective of this study was to examine the clinical outcomes of patients receiving monotherapy with different agents. METHODS This was a retrospective study of adult patients receiving monotherapy for S. maltophilia infection with trimethoprim/sulfamethoxazole (TMP/SMX), a fluoroquinolone, or minocycline from 2010 to 2016. The primary outcome was clinical failure, a composite of recurrence, alteration of therapy due to adverse reaction or concern for clinical failure, or 30-day in-hospital mortality. The secondary outcome was 30-day in-hospital mortality. To account for treatment selection bias, multivariate regression and propensity score weighting were conducted. RESULTS 284 patients were included (217 received TMP/SMX, 28 received a fluoroquinolone, and 39 received minocycline). The TMP/SMX and minocycline groups appeared to include similar patients whereas the fluoroquinolone group appeared to represent a slightly less severely ill population. Clinical failure was similar between groups (36%, 29%, and 31% in the TMP/SMX, fluoroquinolone, and minocycline groups, respectively, P=0.69) as was 30-day mortality (15%, 7%, and 5% in the TMP/SMX, fluoroquinolone, and minocycline groups, respectively, P=0.16). After controlling for confounding factors, receipt of minocycline (adjusted odds ratio [OR]=0.2 [0.1-0.7]) but not a fluoroquinolone (adjusted OR=0.3 [0.1 to 2.1]) was associated with lower mortality compared with TMP/SMX. This association persisted after propensity score weighting. CONCLUSIONS Outcomes were similar or better with alternatives to TMP/SMX monotherapy, which indicates this may not be the treatment of choice for infections caused by S. maltophilia.

Int J Antimicrob Agents 2021; 57:106329. [PMID: 33785363 DOI: 10.1016/j.ijantimicag.2021.106329] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2020] [Revised: 02/19/2021] [Accepted: 03/20/2021] [Indexed: 11/18/2022]
Abstract
Data supporting oral step-down therapy in methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infection (BSI) are sparse; linezolid offers potential in this setting. This study aimed to determine the effectiveness and safety of oral step-down linezolid compared with standard parenteral therapy (SPT) in MRSA-BSI. This was a retrospective cohort performed in adults receiving step-down/outpatient linezolid or SPT (vancomycin, daptomycin) for MRSA-BSI from 2011-2019. Primary outcome was 90-day infection-related re-admission (IRR) from clinical worsening/relapse or infection recurrence. 215 patients included (54 linezolid, 161 SPT). Infection sources were skin (34%), bone/joint (15%), endocarditis (13%), other (32%), multiple (6%). Patients receiving SPT more commonly had complicated bacteraemia (72% vs. 41%; P < 0.0001) and metastatic foci (45% vs. 20%; P = 0.001). 90-day IRR occurred in 17% and 26% of linezolid and SPT groups, respectively (P = 0.159). When accounting for disease severity, linezolid use was not independently associated with 90-day IRR (adjOR, 1.0, 95% CI 0.24-4.3; P = 0.986). There were no differences in all-cause 90-day mortality (4% vs. 6%, P = 0.487) or overall incidence of drug-related adverse events (AEs) (17% vs. 16%; P = 0.843) between the groups. More patients in the SPT group developed an AE requiring re-hospitalisation (12% vs. 2%; P = 0.024), most commonly line-related complications. Oral step-down linezolid demonstrated similar clinical and safety outcomes compared with SPT for MRSA-BSI, except linezolid was associated with fewer AEs requiring re-hospitalisation. Additional research is needed exploring step-down linezolid in MRSA-BSI, particularly in patients requiring shorter durations of outpatient therapy.

Evaluation of the INCREMENT-CPE, Pitt Bacteremia and qPitt Scores in Patients with Carbapenem-Resistant Enterobacteriaceae Infections Treated with Ceftazidime-Avibactam. Infect Dis Ther 2020; 9:291-304. [PMID: 32088843 PMCID: PMC7223509 DOI: 10.1007/s40121-020-00288-4] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Indexed: 01/24/2023] Open
Abstract
BACKGROUND The aim of this study was to evaluate the predictive performance of the INCREMENT-CPE (ICS), Pitt bacteremia score (PBS) and qPitt for mortality among patients treated with ceftazidime-avibactam for carbapenem-resistant Enterobacteriaceae (CRE) infections. METHODS Retrospective, multicenter, cohort study of patients with CRE infections treated with ceftazidime-avibactam between 2015 and 2019. The primary outcome was 30-day all-cause mortality. Predictive performance was determined by assessing discrimination, calibration and precision. RESULTS In total, 109 patients were included. Thirty-day mortality occurred in 18 (16.5%) patients. There were no significant differences in discrimination of the three scores [area under the curve (AUC) ICS 0.7039, 95% CI 0.5848-0.8230, PBS 0.6893, 95% CI 0.5709-0.8076, and qPitt 0.6847, 95% CI 0.5671-0.8023; P > 0.05 all pairwise comparisons]. All scores showed adequate calibration and precision. When dichotomized at the optimal cut-points of 11, 3, and 2 for the ICS, PBS, and qPitt, respectively, all scores had NPV > 90% at the expense of low PPV. Patients in the high-risk groups had a relative risk for mortality of 3.184 (95% CI 1.35-8.930), 3.068 (95% CI 1.094-8.606), and 2.850 (95% CI 1.016-7.994) for the dichotomized ICS, PBS, and qPitt, scores respectively. Treatment-related variables (early active antibiotic therapy, combination antibiotics and renal ceftazidime-avibactam dose adjustment) were not associated with mortality after controlling for the risk scores. CONCLUSIONS In patients treated with ceftazidime-avibactam for CRE infections, mortality risk scores demonstrated variable performance. Modifications to scoring systems to more accurately predict outcomes in the era of novel antibiotics are warranted.

Abstract
Adjustment for confounding is important in observational methicillin-resistant Staphylococcus aureus bacteremia (MRSAB) studies due to the wide spectrum of disease severity and baseline health status that patients present with. The objectives of this study were to develop a simplified MRSAB-specific scoring model to estimate the risk of 30-day all-cause mortality and to compare its performance to the APACHE II and Pitt Bacteremia scores. Retrospective, singe-center, cohort study in adults with MRSAB 2008 to 2018. Independent predictors of mortality were identified through multivariable logistic regression. A scoring model was derived using a regression coefficient-based scoring method. Discriminatory ability was assessed using the c statistic. A total of 455 patients were included. Thirty-day mortality was 16.3%. The MRSAB score consisted of six variables: age, respiratory rate, Glasgow Coma scale, renal failure, hospital-acquired MRSAB, and infective endocarditis or lower respiratory tract infection source. The score demonstrated very good discrimination (c statistic 0.8662, 95% CI 0.824-0.909) and was superior to the APACHE II (P = 0.043) and the Pitt bacteremia (P < 0.001) scores. A weighted combination of six independent variables routinely measured in patients with MRSAB can be used to predict, with high discrimination, 30-day all-cause mortality. External validation is required before widespread use.

Abstract
AIM To assess the accuracy of serum procalcitionin (PCT) as a diagnostic marker in verifying upper and lower gastrointestinal perforation (GIP).
METHODS This retrospective study included 46 patients from the surgical intensive care unit (ICU) of the Second Affiliated Hospital of Harbin Medical University who were confirmed to have GIP between June 2013 and December 2016. Demographic and clinical patient data were recorded on admission to ICU. Patients were divided into upper (n = 19) and lower (n = 27) GIP groups according to the perforation site (above or below Treitz ligament). PCT and WBC count was obtained before laparotomy and then compared between groups. Meanwhile, the diagnostic accuracy of PCT was analyzed.
RESULTS Patients with lower GIP exhibited significantly higher APACHE II score, SOFA score and serum PCT level than patients with upper GIP (P = 0.017, 0.004, and 0.001, respectively). There was a significant positive correlation between serum PCT level and APACHE II score or SOFA score (r = 0.715 and r = 0.611, respectively), while there was a significant negative correlation between serum PCT level and prognosis (r = -0.414). WBC count was not significantly different between the two groups, and WBC count showed no significant correlation with serum PCT level, APACHE II score, SOFA score or prognosis. The area under the receiver operating characteristic curve of PCT level to distinguish upper or lower GIP was 0.778. Patients with a serum PCT level above 17.94 ng/dL had a high likelihood of lower GIP, with a sensitivity of 100% and a specificity of 42.1%.
CONCLUSION Serum PCT level is a reliable and accurate diagnostic marker in identifying upper or lower GIP before laparotomy.

Abstract
Data suggest that vancomycin is less effective for methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infection (BSI) with vancomycin Etest® MIC (MICEtest) ≥1.5 mg/L. No published studies have evaluated the relationship between vancomycin exposure and outcomes among patients with MRSA BSIs vancomycin MICEtest ≥1.5 mg/L. This study was a retrospective cohort of 71 hospitalized, adult, non-dialysis patients with MRSA BSIs treated with vancomycin. All but three patients had a vancomycin MICEtest of 1.5 mg/L. Achievement of CART-derived AUC24-48h of at least 550 mg*h/L (AUC24-48h/MIC of 366 mg*h/L) was associated with a lower incidence of treatment failure. In multivariate analyses, the risk ratio was 0.45 for the CART-derived AUC24-48h threshold, indicating that achievement of the CART-derived AUC24-48h threshold of 550 was associated with a 2-fold decrease in treatment failure. These findings suggest a potential association between vancomycin exposure and outcomes in patients with MRSA BSIs with MICEtest ≥1.5 mg/L. As this study was retrospective, these findings provide the basis for a future large-scale, multi-center prospective study.

Abstract
Novel therapies for methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infection (BSI) are needed in the setting of reduced antibiotic susceptibilities and therapeutic failure. Ceftaroline is a cephalosporin antibiotic with MRSA activity. Although not FDA approved for MRSA BSI, ceftaroline has generated much interest as a potential treatment option. However, detailed descriptions of its use in this setting remain limited. To address this, we conducted a retrospective, multicenter, observational study of adult patients with MRSA BSI treated with at least 72 h of ceftaroline from 2011 to 2015. Safety outcomes were examined in the overall cohort, while efficacy outcomes were examined among patients who had not cleared their BSI prior to ceftaroline initiation. Data were also stratified by ceftaroline monotherapy or combination therapy. Predictors of clinical failure on ceftaroline treatment were also sought. Overall, 211 patients were included in the safety population; Clostridium difficile infection, rash, and neutropenia occurred in 6 patients (2.8%), 7 patients (3.3%), and 3 patients (1.4%), respectively. Clinical success was observed in 86 (68.3%) of the 126 patients included in the efficacy population. The monotherapy and combination therapy subgroups had similar proportions of patients experiencing success (69.7 and 64.9%, respectively). The median BSI durations post-ceftaroline treatment were 2 days (interquartile range, 1 to 4 days) for monotherapy and 3 days (interquartile range, 1.5 to 5 days) for combination therapy. Higher acute physiology and chronic health evaluation II scores and comorbid malignancy independently predicted treatment failure. Ceftaroline appears effective for MRSA BSI as both monotherapy and combination therapy. However, comparative studies are needed to further delineate the role of ceftaroline in MRSA BSI treatment.

Abstract
Background Vancomycin (VCM) requires dose adjustment based on therapeutic drug monitoring. At Aomori Prefectural Central Hospital, physicians carried out VCM therapeutic drug monitoring based on their experience, because pharmacists did not participate in the dose adjustment. We evaluated the impact of an Antimicrobial Stewardship Program (ASP) on attaining target VCM trough concentrations and pharmacokinetics (PK)/pharmacodynamics (PD) parameters in patients with methicillin-resistant Staphylococcus aureus (MRSA) infections. Materials and methods The ASP was introduced in April 2012. We implemented a prospective audit of prescribed VCM dosages and provided feedback based on measured VCM trough concentrations. In a retrospective pre- and postcomparison study from April 2007 to December 2011 (preimplementation) and from April 2012 to December 2014 (postimplementation), 79 patients were treated for MRSA infection with VCM, and trough concentrations were monitored (pre, n=28; post, n=51). In 65 patients (pre, n=15; post, n=50), 24-hour area under the concentration–time curve (AUC 0–24 h)/minimum inhibitory concentration (MIC) ratios were calculated. Results Pharmacist feedback, which included recommendations for changing dose or using alternative anti-MRSA antibiotics, was highly accepted during postimplementation (88%, 29/33). The number of patients with serum VCM concentrations within the therapeutic range (10–20 μg/mL) was significantly higher during postimplementation (84%, 43/51) than during preimplementation (39%, 11/28) (P<0.01). The percentage of patients who attained target PK/PD parameters (AUC 0–24 h/MIC >400) was significantly higher during postimplementation (84%, 42/50) than during preimplementation (53%, 8/15; P=0.013). There were no significant differences in nephrotoxicity or mortality rate. Conclusion Our ASP increased the percentage of patients that attained optimal VCM trough concentrations and PK/PD parameters, which contributed to the appropriate use of VCM in patients with MRSA infections.

Abstract
The aim of this study was to identify patients with methicillin-resistant Staphylococcus aureus (MRSA) bacteremia with low risk of infective endocarditis (IE) who might not require routine trans-esophageal echocardiography (TEE). We retrospectively evaluated 398 patients presenting with MRSA bacteremia for the presence of the following clinical criteria: intravenous drug abuse (IVDA), long-term catheter, prolonged bacteremia, intra-cardiac device, prosthetic valve, hemodialysis dependency, vertebral/nonvertebral osteomyelitis, cardio-structural abnormality. IE was diagnosed using the modified Duke criteria. Of 398 patients with MRSA bacteremia, 26.4 % of cases were community-acquired, 56.3 % were health-care-associated, and 17.3 % were hospital-acquired. Of the group, 44 patients had definite IE, 119 had possible IE, and 235 had a rejected diagnosis. Out of 398 patients, 231 were evaluated with transthoracic echocardiography (TTE) or TEE. All 44 patients with definite IE fulfilled at least one criterion (sensitivity 100 %). Finally, a receiver operator characteristic (ROC) curve was obtained to evaluate the total risk score of our proposed criteria as a predictor of the presence of IE, and this was compared to the ROC curve of a previously proposed criteria. The area under the ROC curve for our criteria was 0.710, while the area under the ROC curve for the criteria previously proposed was 0.537 (p < 0.001). The p-value for comparing those 2 areas was less than 0.001, indicating statistical significance. Patients with MRSA bacteremia without any of our proposed clinical criteria have very low risk of developing IE and may not require routine TEE.

Abstract
We describe outcomes of patients with infections with carbapenem-resistant Klebsiella pneumoniae (CRKP) who received ertapenem-containing double-carbapenem therapy (ECDCT). Clinical success was observed in 7/18 (39%) patients overall: bloodstream infections, 3/7 (43%); pneumonia, 1/5 (20%); intraabdominal infections, 0/2 (0%); urinary tract infections, 2/3 (67%); and a skin and skin structure infection, 1/1 (100%). Microbiologic success was observed in 11/14 (79%) evaluable patients; 5/18 (28%) patients died. ECDCT may be effective for CRKP infections with limited treatment options.

Abstract
BACKGROUND Although sepsis is one of the leading causes of mortality in hospitalized patients, information regarding early predictive factors for mortality and morbidity is limited. MATERIALS AND METHODS Patients fulfilling the Infectious Disease Society of America criteria of sepsis within the medical intensive care unit (ICU) were included over two years. Apart from baseline hematological, biochemical, and metabolic parameters, Acute Physiology and Chronic Health Evaluation II (APACHE II), Simplified Acute Physiology Score II and III (SAPS II and SAPS III), and Sequential Organ Function Assessment (SOFA) scores were calculated on day 1 of admission. Patients were followed till death or discharge from the ICU. RESULTS One hundred patients were enrolled over two years (54% males). The overall mortality was 53%, (69.5% in females, 38.8% in males (P < 0.01). Mortality was 65.7%, 55.7%, and 33.3% in patients with septic shock, severe sepsis, and sepsis, respectively. Patients who died were significantly older than the survivors (mean age, 57.37 ± 20.42 years and 44.29 ± 15.53 years respectively, P < 0.01). Nonsurvivors were significantly more anemic and had higher APACHE II, SAPS II, SAPS III, and SOFA scores. The presence of acute respiratory distress syndrome and renal dysfunction were associated with higher mortality (75% and 70.2%, respectively). There was no significant difference in the duration of mechanical ventilation or ICU stay between survivors and nonsurvivors. On multivariate analysis, significant predictors of mortality with odds ratio greater than 2 included the presence of anemia, SAPS II score greater than 35, SAPS III score greater than 47, and SOFA score greater than 6 at day 1 of admission. CONCLUSION Several demographic and laboratory parameters as well as composite critical illness scoring systems are reliable early predictors of mortality in sepsis. A sepsis mortality prediction formula (AIIMS Sepsis Score) based on SAPS II, SAPS III, and SOFA scores and hemoglobin has greater predictive power than these scoring methods individually. Routine use of critical illness scoring systems and a composite mortality prediction formula may provide useful early prognostic information in sepsis/severe sepsis.

Abstract
BACKGROUND Although many studies have estimated the impact of health care-associated methicillin-resistant Staphylococcus aureus (MRSA) infections on mortality during initial hospitalization, little is known about the long-term risk of death in these patients. The purpose of this study was to quantify the effect of MRSA health care-acquired infections (HAIs) on mortality after hospital discharge. METHODS Our study cohort consisted of patients with inpatient admission within the U.S. Department of Veterans Affairs system between October 1, 2007, and September 30, 2010. Of these patients, we identified those with a positive MRSA culture from electronic microbiology reports. We constructed multivariable Cox proportional hazards regressions to assess the impact of a positive culture on postdischarge mortality in the 365 days following discharge using both the full cohort and a propensity score-matched subsample. RESULTS In our analysis cohort of 369,743 inpatients, positive MRSA cultures were recorded in 3,599 (1.0%) patients. We found that positive cultures resulted in an increased risk of postdischarge mortality both in the full cohort (hazard ratio = 1.42, P < .001) and in the subset of propensity score-matched patients (hazard ratio = 1.37, P < .0001). CONCLUSION We found that MRSA HAIs significantly elevate the long-term risk of mortality. These results underscore the importance of infection prevention efforts in the hospital.

Abstract
Strains of third-generation-cephalosporin-resistant Klebsiella pneumoniae (3GCRKP) and carbapenem-resistant K. pneumoniae (CRKP) are rapidly spreading. Evidence is needed to establish whether differences exist between patients at risk for 3GCRKP and those at risk for CRKP bloodstream infections (BSIs); thus, this retrospective case-case-control study was conducted to determine if the risk factors for these two infections differ. The inclusion criteria for cases were positive blood cultures for K. pneumoniae, first episode of BSI, age of ≥18 years, and susceptibility results indicating resistance to either third-generation cephalosporins (3GCRKP group) or carbapenems and cephalosporins (CRKP group). Controls were patients admitted for ≥72 h and were matched to cases by month/year and medical unit. Variables of interest were analyzed by univariate analysis, and those of significance were analyzed by logistic regression. In total, 111 patients with 3GCRKP BSIs and 43 patients with CRKP BSIs were matched to 154 controls. Multivariate analyses of 3GCRKP case and control groups demonstrated that a length of stay (LOS) of >40 days (odds ratio [OR], 17.7; 95% confidence interval [CI], 3.7 to 84.3), the use of antibiotics in the past 90 days (OR, 4.3; 95% CI, 1.5 to 11.9), and the presence of a central venous catheter (OR, 4.1; 95% CI, 1.3 to 13.4) were independent risk factors. Multivariate analyses of the CRKP case and control groups demonstrated that a LOS of >40 days (OR, 13.5; 95% CI, 2.9 to 62.8) and the use of antibiotics in the past 90 days (OR, 5.9; 95% CI, 1.3 to 26.5) were independent risk factors. Similar factors put patients at risk for these two types of K. pneumoniae BSIs.

Abstract
Background Prognostic abilities of medical parameters, which are scoring systems, measurements and biomarkers, are important for stratifying critically ill patients. Indocyanine green plasma disappearance (ICG-PDR) is an established clinical tool for the assessment of liver perfusion and function. Copeptin, MR-proANP and pro-ADM are biomarkers whose prognostic value is still unclear. The goal of this prospective study was to evaluate ICG-PDR, copeptin, MR-proANP and pro-ADM to predict prolonged length of stay (pLOS) in the ICU. Methods This study was conducted as a prospective single center study including 110 consecutively admitted ICU patients. Primary endpoint was prolonged length of stay (pLOS) in the ICU, defined as more than three days of stay there. Results ROC analysis showed an AUC of 0.73 for ICG-PDR, 0.70 for SAPS II, 0.65 for MR-proANP, 0.64 for pro-ADM and 0.54 for copeptin for pLOS in the ICU. Conclusions The prediction of pLOS in the ICU might be better by means of ICG-PDR than with the new biomarkers copeptin, MR-proANP or pro-ADM. Nevertheless, there is more need for research to evaluate whether ICG-PDR is an overall prognostic marker for pLOS. Trial registration (ClinicalTrials.gov number, NCT01126554).

Abstract
Background Mortality among critically ill patients with candidemia is very high. We sought to determine whether the choice of initial antifungal therapy is associated with survival among these patients, using need for mechanical ventilatory support as a marker of critical illness. Methods Cohort analysis of outcomes among mechanically ventilated patients with candidemia from the 24 North American academic medical centers contributing to the Prospective Antifungal Therapy (PATH) Alliance registry. Patients were included if they received either fluconazole or an echinocandin as initial monotherapy. Results Of 5272 patients in the PATH registry at the time of data abstraction, 1014 were ventilated and concomitantly had candidemia, with 689 eligible for analysis. 28-day survival was higher among the 374 patients treated initially with fluconazole than among the 315 treated with an echinocandin (66% versus 51%, P < .001). Initial fluconazole therapy remained associated with improved survival after adjusting for non-treatment factors in the overall population (hazard ratio .75, 95% CI .59–.96), and also among patients with albicans infection (hazard ratio .62, 95% CI .44–.88). While not statistically significant, fluconazole appeared to be associated with higher mortality among patients infected with glabrata (HR 1.13, 95% CI .70–1.84). Conclusions Among ventilated patients with candidemia, those receiving fluconazole as initial monotherapy were significantly more likely to survive than those treated with an echinocandin. This difference persisted after adjustment for non-treatment factors.

Abstract
INTRODUCTION Clinical scoring systems are used to predict mortality rate in hospitalized patients. Their utility in organophosphate (OP) poisoning has not been well studied. METHODS In this retrospective study of 396 patients, we evaluated the performance of the Acute Physiology and Chronic Health Evaluation (APACHE) II score, the Simplified Acute Physiology Score (SAPS) II, Mortality Prediction Model (MPM) II, and the Poisoning Severity Score (PSS). Demographic, laboratory, and survival data were recorded. Receiver operating characteristic (ROC) curves were generated, and the area under the curve (AUC) was calculated to study the relationship between individual scores and mortality rate. RESULTS The mean (standard deviation) age of the patients was 31.4 (12.7) years, and at admission, their pseudocholinesterase (median, interquartile) level was 317 (222-635) U/L. Mechanical ventilation was required in 65.7% of the patients and the overall mortality rate was 13.1%. The mean (95% confidence interval) scores were as follows: APACHE-II score, 16.4 (15.5-17.3); SAPS-II, 34.4 (32.5-36.2); MPM-II score, 28.6 (25.7-31.5); and PSS, 2.4 (2.3-2.5). Overall, the AUC for mortality was significantly higher for APACHE-II (0.77) and SAPS-II (0.77) than the PSS (0.67). When patients were categorized, the AUCs were better for WHO Class II (0.71-0.82) than that for Class I compounds (0.60-0.66). For individual compounds, the AUC for APACHE-II was highest in quinalphos (0.93, n = 46) and chlorpyrifos (0.86, n = 38) and lowest in monocrotophos (0.60, n = 63). AUCs for SAPS-II and MPM-II were marginally but not significantly lower than those for APACHE-II. The PSS was generally a poorer discriminator compared to the other scoring systems across all categories. CONCLUSIONS In acute OP poisoning, the generic scoring systems APACHE-II and SAPS-II outperform the PSS. These tools may be used to predict the mortality rate in OP poisoning.
