Computational design of mechanically coupled axle-rotor protein assemblies.

Natural molecular machines contain protein components that undergo motion relative to each other. Designing such mechanically constrained nanoscale protein architectures with internal degrees of freedom is an outstanding challenge for computational protein design. Here we explore the de novo construction of protein machinery from designed axle and rotor components with internal cyclic or dihedral symmetry. We find that the axle-rotor systems assemble in vitro and in vivo as designed. Using cryo-electron microscopy, we find that these systems populate conformationally variable relative orientations reflecting the symmetry of the coupled components and the computationally designed interface energy landscape. These mechanical systems with internal degrees of freedom are a step toward the design of genetically encodable nanomachines.

Relationships between subjective taste sensations and electrogustometry findings in patients with taste disorders.

This study aimed to examine the relationships between subjective taste sensations and electrogustometry (EGM) findings in patients with taste disturbances according to the presence of burning mouth (BM) symptoms. Forty-six patients were included and asked to complete a questionnaire that contained questions on subjective taste sensations for the four basic taste qualities and the pattern of taste disorders such as ageusia, hypogeusia and dysgeusia. EGM was performed to measure detection thresholds. To examine the influence of BM symptoms, patients were divided into two groups: patients with and without BM symptoms. The patients consisted of 11 men and 35 women. The group without BM symptoms (n=26) had significantly lower degrees of subjective taste sensations for all taste qualities and higher correlation levels between subjective taste sensations and EGM thresholds than the group with BM symptoms (n=20). The patterns of taste disorders also showed more significant associations with the levels of subjective taste sensations in the patients without BM symptoms compared with those with BM symptoms. In conclusion, patients with taste disorders without BM symptoms had more severe taste disturbances than those with BM symptoms. The pathophysiology of taste disturbances differs according to the presence or absence of BM symptoms.

Effect of acupuncture and intervention types on weight loss: a systematic review and meta-analysis.

This study aimed to evaluate the effect of acupuncture and intervention types on weight loss. We searched electronic databases, including Embase, PubMed, CENTRAL, RISS, KISS and CNKI, for randomized controlled trials that used acupuncture to treat obesity before June 2017. We found 27 trials involving 32 intervention arms and 2,219 patients. Acupuncture plus lifestyle modification (LM) was more effective than LM alone (Hedges' g = 1.104, 95% CI = 0.531-1.678) and sham acupuncture plus LM (Hedges' g = 0.324, 95% CI = 0.177-0.471), whereas acupuncture alone was not more effective than sham acupuncture alone and no treatment. Auricular acupuncture (Hedges' g = 0.522, 95% CI = 0.152-0.893), manual acupuncture (Hedges' g = 0445, 95% CI = 0.044-0.846) and pharmacopuncture (Hedges' g = 0.411, 95% CI = 0.026-0.796) favoured weight loss. Finally, acupuncture treatment was effective only in subjects with overweight (25 ≤ body mass index < 30, Hedges' g = 0.528, 95% CI = 0.279-0.776), not in subjects with obesity (body mass index ≥30). Our study suggests that the effect of acupuncture on weight loss may be maximized when auricular and manual acupuncture or pharmacopuncture treatment is combined with LM in patients with overweight.

Recent Results of In Situ Abdominal Aortic Reconstruction with Cryopreserved Arterial Allograft.

OBJECTIVE: To evaluate treatment outcomes of in situ abdominal aortic reconstruction with cryopreserved arterial allograft (CAA) for patients with abdominal aortic infection. MATERIALS AND METHODS: A retrospective review of prospectively collected data was conducted of patients who underwent in situ aortic reconstruction using CAA for primary, secondary, or prosthetic infection of the abdominal aorta between May 2006 and July 2015, at a single institution. Clinical presentation, indications for treatment, procedural details, early post-operative mortality and morbidity, late death, and graft related complications during the follow up period were investigated. Patient survival and event free survival (any death or re-operation) were calculated using the Kaplan-Meier method. RESULTS: Twenty-five patients (male, n = 20, 80%; mean age, 70.2 ± 8.7 years) underwent in situ abdominal aortic reconstruction (48% aortic, 52% aorto-bi-iliac) with vessel size and ABO matched CAA for treatment of abdominal aortic infection caused by infected abdominal aortic aneurysm (n = 15), aortic prosthesis infection (n = 7), aortic reconstruction with concomitant colon resection (n = 2), and primary suppurative aortitis (n = 1). The median follow up was 19.1 months (range 1-73 months). There were seven post-operative deaths including two (8%) early (<30 days) and five (20%) late deaths There were three (12%) graft related complications including thrombotic occlusion of the CAA, aneurysmal dilatation, and aorto-enteric fistula. Three years after CAA implantation, patient survival was 74% and the event free survival was 58%. CONCLUSIONS: It is believed that in situ abdominal aortic reconstruction with CAA is a useful option for treating primary, secondary, or prosthetic infection of the abdominal aorta.

Angiopoietin 2 induces astrocyte apoptosis via αvß5-integrin signaling in diabetic retinopathy.

The vascular leakage in diabetic retinopathy leads to macular edema and vision loss. Although astrocyte play an important role in regulating blood-brain barrier integrity in the brain, the precise role of astrocyte in blood-retinal barrier was yet to be elucidated. This study aimed to investigate the role of angiopoietin 2 (Ang2) in astrocyte loss and vascular leakage in the early streptozotocin-induced diabetic retinopathy. We demonstrated that vascular leakage occurred with astrocyte loss in early diabetic mice retina as Ang2 increased. The astrocyte loss and vascular leakage were inhibited by intravitreal injection of Ang2-neutralizing antibody. In vitro, Ang2 aggravated high glucose-induced astrocyte apoptosis via GSK-3ß activation. Ang2 directly bound to αvß5 integrin, which was abundant in astrocyte, and the blockade of αvß5 integrin, in vitro, effectively attenuated Ang2-induced astrocyte apoptosis. In vivo, intravitreal injection of anti-αvß5-integrin antibody inhibited astrocyte loss in early diabetic retinopathy. Taken together, Ang2 induced astrocyte apoptosis under high glucose via αvß5-integrin/GSK-3ß/ß-catenin pathway. Therefore, we suggest that Ang2/integrin signaling could be a potential therapeutic target to prevent the vascular leakage by astrocyte loss in early diabetic retinopathy.

The effect of sandblasting and different primers on shear bond strength between yttria-tetragonal zirconia polycrystal ceramic and a self-adhesive resin cement.

PURPOSE: To evaluate the effect of zirconia primers, air-abrasion, and tribochemical surface treatment methods on the shear bond strength between yttria-tetragonal zirconia polycrystal (Y-TZP) ceramic and self-adhesive resin cement. METHODS AND MATERIALS: Y-TZP ceramic surfaces were ground flat with 600-grit silicon carbide paper and then divided into seven groups of 10 and treated as follows: untreated (control), Monobond Plus, Z-PRIME Plus, ESPE Sil with CoJet, air-abrasion, Monobond Plus with air-abrasion, and Z-PRIME Plus with air-abrasion. Self-adhesive resin cement was placed onto the treated Y-TZP specimens for each group. All specimens were thermocycled and subjected to a shear bond strength test. Scanning electron microscope images of the fractured areas and x-ray diffraction (XRD) analysis of the surface-treated Y-TZP specimens were performed. Data were statistically analyzed using one-way analysis of variance and the Student-Newman-Keuls multiple comparison test (p<0.05). RESULTS: The Z-PRIME Plus treatment in combination with air-abrasion produced the highest bond strength (16.50±2.26 MPa), followed by air-abrasion (10.56±3.32 MPa), and then Monobond Plus combined with air-abrasion (8.93±3.13 MPa), ESPE Sil after CoJet application (8.54±3.98 MPa), and the Z-PRIME Plus group (8.27±2.79 MPa). The control (3.91±0.72 MPa) and Monobond Plus (4.86±1.77 MPa) groups indicated the lowest results (p<0.05). The XRD results showed the peaks of the monoclinic phase for the air-abrasion and CoJet treatment groups compared with the Y-TZP control. CONCLUSION: Z-PRIME Plus primer application after air-abrasion presented the best results for improving the bond strength between Y-TZP ceramic and self-adhesive resin cement.

Sodium nitroprusside suppresses male fertility in vitro.

Sodium nitroprusside is a nitric oxide donor involved in the regulation of the motility, hyperactivation, capacitation, and acrosome reaction (AR) of spermatozoa. However, the molecular mechanism underlying this regulation has not yet been elucidated. Therefore, this study was designed to evaluate the molecular basis for the effects of sodium nitroprusside on different processes in spermatozoa and its consequences on subsequent oocyte fertilization and embryo development. In this in vitro study, mouse spermatozoa were incubated with various concentrations of sodium nitroprusside (1, 10, and 100 µM) for 90 min. Our results showed that sodium nitroprusside inhibited sperm motility and motion kinematics in a dose-dependent manner by significantly enhancing intracellular iron and reactive oxygen species (ROS), and decreasing Ca(2+), and adenosine triphosphate levels in spermatozoa. Moreover, short-term exposure of spermatozoa to sodium nitroprusside increased the tyrosine phosphorylation of sperm proteins involved in PKA-dependent regulation of intracellular calcium levels, which induced a robust AR. Finally, sodium nitroprusside significantly decreased the rates of fertilization and blastocyst formation during embryo development. Based on these results, we propose that sodium nitroprusside increases ROS production and precocious AR may alter overall sperm physiology, leading to poor fertilization and compromised embryonic development.

Shear bond strength of four different repair materials applied to bis-acryl resin provisional materials measured 10 minutes, one hour, and two days after bonding.

This study investigated the shear bond strength of repaired provisional restoration materials 1) to compare the bond strengths between bis-acryl resin and four different materials and 2) to investigate the effect of the amount of time elapsed after bonding on the bond strength. The self-cured bis-acryl resin (Luxatemp) was used as the base material, and four different types of resins (Luxatemp, Protemp, Z350 flowable, and Z350) were used as the repair materials. Specimens were divided into three groups depending on the point of time of shear bond strength measurement: 10 minutes, one hour, and 48 hours. Shear bond strengths were measured with a universal testing machine, and the fracture surface was examined with a video measuring system. Two-way analysis of variance revealed that the repair materials (p<0.001) and the amount of time elapsed after bonding (p<0.001) significantly affected the repair strength. All of the repaired materials showed increasing bond strength with longer storage time. The highest bond strength and cohesive failure were observed for bonding between Luxatemp base and Luxatemp at 48 hours after bonding.

Prediction of subclinical atherosclerosis by serum osteoprotegerin in premenopausal women with systemic lupus erythematous: correlation of osteoprotegerin with monocyte chemotactic protein-1.

OBJECTIVE: Patients with systemic lupus erythematosus (SLE) have increased risk for cardiovascular disease. Previous studies disclosed the association of serum osteoprotegerin (OPG) with the presence of symptomatic atherosclerosis in the general population and several disease conditions. We thus investigated the association between serum OPG levels and subclinical atherosclerosis in premenopausal SLE patients. METHODS: Serum OPG levels and carotid artery intima-media thickness (IMT) were measured in 181 premenopausal SLE patients and age-matched 85 control subjects. Traditional cardiovascular risk factors and SLE-related factors were analyzed. RESULTS: Patients with SLE had significantly increased serum OPG levels (1086 versus 517 pg/ml, p < 0.001) and carotid IMT (0.63 versus 0.45 mm, p < 0.001) compared with control subjects. Carotid IMT significantly increased across the quartiles of OPG. Logistic regression analysis revealed that compared to the lowest OPG quartile, the odds ratio (OR, 95% confidence interval) for increased carotid IMT in quartile 2, 3, and 4 was 1.126 (1.013-1.801), 1.562 (1.268-2.799), and 4.460 (1.126-7.128), respectively, after multiple adjustments (p for trend across quartiles < 0.001). These associations remained significant after further adjustment for inflammatory parameters. Interestingly, serum monocyte chemotactic protein-1 (MCP-1) levels were positively correlated with serum OPG levels (γ = 0.332, p < 0.001). Parallel analysis showed that serum MCP-1 was also an independent predictor of carotid IMT incrassation, but this association was lost when serum OPG was included in the model. CONCLUSION: Serum OPG levels were increased and correlated with serum MCP-1 levels in premenopausal SLE patients. Increased serum OPG was independently associated with subclinical atherosclerosis in these patients.

Enhanced antitumor immunotherapeutic effect of B-cell-based vaccine transduced with modified adenoviral vector containing type 35 fiber structures.

For successful clinical tumor immunotherapy outcomes, strong immune responses against tumor antigens must be generated. Cell-based vaccines compromise one strategy with which to induce appropriate strong immune responses. Previously, we established a natural killer T-cell (NKT) ligand-loaded, adenoviral vector-transduced B-cell-based anticancer cellular vaccine. To enhance tumor antigen delivery to B cells, we established a modified adenoviral vector (Ad-k35) that encoded a truncated form of the breast cancer antigen Her2/neu (Ad-k35HM) in which fiber structure was substituted with adenovirus serotype 35. We observed increased tumor antigen expression with Ad-k35HM in both human and murine B cells. In addition, an Ad-k35HM-transduced B-cell vaccine elicited strong antigen-specific cellular and humoral immune responses that were further enhanced with the additional loading of soluble NKT ligand KBC009. An Ad-k35HM-transduced, KBC009-loaded B-cell vaccine efficiently suppressed the in vivo growth of established tumors in a mouse model. Moreover, the vaccine elicited human leukocyte antigen (HLA)-A2 epitope-specific cytotoxic T-cell responses in B6.Cg (CB)-Tg (HLA-A/H2-D) 2Enge/Jat mice. These findings indicated that the Ad-k35 could be appropriate for the preclinical and clinical development of B-cell-based anticancer immunotherapies.

Automated screening for tuberculosis by multiparametric analysis of data obtained during routine complete blood count.

INTRODUCTION: The main goal of this study was to develop a multiparametric cell population data (CPD) model that combines information from several morphologic parameters generated by DxH800, in addition to the traditional parameters regularly reported in the CBC-diff, and to test the performance of this model in screening the general population for primary tuberculosis (TB). METHODS: A total of 3741 study cases were divided into two groups, test and validation set at cut-off value of 6000 WBCs/µL. We developed multiparametric model for primary TB screening (TB hemeprint), selected CPD, and calculated parameters which could discriminate primary TB from other non-TB diseases and normal control in test set. We applied it to the validation set, which was a set of completely different samples, to test its reproducibility if applied to a routine laboratory test. RESULTS: After screening primary TB using TB hemeprint, sensitivity, specificity, PPV, and NPV were 85.4%, 89.6%, 31.1%, and 99.1%, respectively, in primary TB with lower than 6000 WBCs/µL of test set (test set-L). In primary TB with higher than 6000 WBCs/µL of test set (test set-H), those values were 83.1%, 85.6%, 29.7%, and 98.6%, respectively. There were only 0.4% (2/461) and 0.6% (2/326) of normal control samples included in test set-L and -H, respectively. Diagnostic efficiencies except sensitivity in each validation set were very comparable with those in each test set. CONCLUSION: Tuberculosis hemeprint may allow us to screen primary TB with acceptable sensitivity and specificity using combination of TB-specific CPD and calculated parameters.

The role of thioredoxin 1 in the mycophenolic acid-induced apoptosis of insulin-producing cells.

Mycophenolic acid (MPA) is one of many effective immunosuppressive drugs. However, MPA can induce cellular toxicity and impair cellular function in ß-cells. To explore the effects of MPA and the relation between MPA and Trx-1, we used various methods, including an Illumina microarray, to identify the genes regulated during pancreatic ß-cell death following MPA treatment. INS-1E cells (a pancreatic ß-cell line) and isolated rat islets were treated with MPA for 12, 24, or 36 h, and subsequent microarray analysis showed that (Trx1) gene expression was significantly reduced by MPA. Further, Trx1 overexpression increased the cell viability, decreased the activations of c-jun N-terminal kinase (JNK) and caspase-3 by MPA, and attenuated ROS upregulation by MPA. Furthermore, siRNA knockdown of Trx1 increased MPA-induced cell death and the activations of p-JNK and caspase-3, and MPA significantly provoked the apoptosis of insulin-secreting cells via Trx1 downregulation. Our findings suggest that the prevention of Trx1 downregulation in response to MPA is critical for successful islet transplantation.

Risk factors for recurrent urinary tract infection in kidney transplant recipients.

BACKGROUND: Urinary tract infections (UTIs) are the most common infectious complication in kidney transplant recipients (KTRs). The aim of this study to investigate the risk factors for and causative organisms of UTI as well as to evaluate the impact these diseases on allograft function in KTRs. METHODS: We analyzed patients who underwent kidney transplantation (KT) between January 2000 and December 2010. Among a total of 344 KTRs, 50 (14.5%) patients experienced 106 UTI episodes during a mean follow-up of 35.9 ± 26.0 months. Twenty three patients experiencing recurrent UTI were compared with 27 nonrecurrent UTI patients and with 50 non-UTI patients matched for age, gender, and transplantation date. RESULTS: The number of patients with renal calculi, diabetes, or prior dialysis was significantly greater among the UTI group compared with control subjects. In addition, the number of patients with renal calculi was significantly higher among the recurrent compared with the nonrecurrent cohort (43.5 vs 7.4%; P = .003). The most common causative organism was Escherichia coli (64.1%), followed by Enterococcus species (20.5%). Higher rates of antibiotic resistance, especially Extended Spectrum Beta-Lactamasc (ESBL) production, were observed among the recurrent compared with the nonrecurrent group (53.1 vs 0%; P = .013). The rate of decline of estimated glomerular filtration rate was significantly faster in the UTI than the non-UTI group, whereas it did not differ between the recurrent and nonrecurrent group. CONCLUSIONS: Adequate treatment of an initial UTI to prevent as recurrent infection and prolong graft longevity is especially reasonable for KTRs with renal calculi or in cases of antibiotic-resistant microorganisms.

Antimicrobial efficacy of a human ß-defensin-3 peptide using an Enterococcus faecalis dentine infection model.

AIM: To assess the antibacterial efficacy of a human ß-defensin-3 (HBD3) peptide against Enterococcus faecalis biofilms. METHODOLOGY: Standardized human dentine blocks were infected with E. faecalis ATCC 29212 for 3 weeks. Aqueous calcium hydroxide paste (n = 12, CH), a 2% chlorhexidine gel (n = 12, CHX), an HBD3 peptide gel (n = 12) and saline (n = 12) were tested as experimental groups. A mismatched peptide gel group (n = 12, MP) and sterilized but noninoculated block group (n = 12) were included as controls. After 1 week of medication, the dentinal samples at the depth of 200 and 400 µm were collected from medicated canal lumens. Bacterial growth was assessed by spectrophotometric analysis of optical density (OD) after 72 h of incubation. Statistical analysis was performed with repeated-measures anova and Tukey's post hoc test. RESULTS: The HBD3 group was associated with significantly lower OD values (P < 0.05) than the CH or CHX groups at both depths. The CH group did not differ significantly from MP or Saline group at either depth (P > 0.05). There was no significant difference (P > 0.05) in the OD values of the inner (200 µm) and outer (400 µm) dentinal samples for any group. CONCLUSIONS: The HBD3 peptide inhibited the growth of E. faecalis biofilms in infected dentine blocks.

Prevalence, awareness, treatment and control of hypertension in adults with diagnosed diabetes: the Fourth Korea National Health and Nutrition Examination Survey (KNHANES IV).

We evaluated the prevalence, awareness, treatment and control of hypertension in Korean adults with diagnosed diabetes using nationally representative data. Among subjects aged ≥30 years who participated in the Fourth Korea National Health and Nutrition Examination Survey in 2007 and 2008, a total of 745 subjects (336 men and 409 women) with a previous diagnosis of diabetes mellitus were analyzed. The prevalence of hypertension in adults with diagnosed diabetes was 55.5%. The rates of awareness, treatment and control were 88.0, 94.2, and 30.8%, respectively. Compared with the general population, the prevalence of hypertension in adults with diagnosed diabetes was higher in all age groups in both genders. Factors independently associated with a high prevalence of hypertension included being male, increasing age, single, <9 years of education, the presence of chronic kidney disease risk, hypercholesterolemia (≥240 mg dl(-1)) and high body mass index (≥25 kg m(-2)). Regular medical screening was positively associated with hypertension control, whereas a high triglyceride level (≥150 mg dl(-1)) was inversely associated. A high prevalence and a low control rate of hypertension in adults with diagnosed diabetes suggest that stringent efforts are needed to control blood pressure in diabetic patients.

SCAR markers for discriminating species of two genera of medicinal plants, Liriope and Ophiopogon.

The development of DNA markers that can closely discriminate between Liriope and Ophiopogon species is vital for efficient and accurate identification of these species, and to ensure the quality, safety, and efficacy of medicines made from these plants. We developed species-specific molecular markers for these two genera. Forty RAPD primers were tested to detect polymorphism; species-specific RAPD bands were gel-purified, cloned, and sequenced. Primers for sequence-characterized amplified regions (SCARs) were then designed, based on nucleotide sequences of specific RAPD primers. SCAR markers SA06 and SB05, specific to Ophiopogon japonicus, amplified 460- and 553-bp DNA fragments, respectively. The marker SA12 amplified a 485-bp fragment specific to Liriope platyphylla. This is the first report of a species-specific SCAR marker for this group. These markers will be useful for rapid identification of closely related Liriope and Ophiopogon species.

Cellular function of RhoGDI-α mediates the cycling of Rac1 and the regulation of pancreatic beta cell death.

Mycophenolic acid (MPA) is an immunosuppressive agent that is widely used in clinical therapy, including pancreas and islet transplantation. Previously, we showed that MPA induces significant apoptosis of insulin-secreting cells by downregulating RhoGDI-α and increasing JNK expression. In this study, we investigated Rac1 directly associated with RhoGDI-α during MPA-induced apoptosis in INS-1E cells (an insulin-secreting cell line). Cells were treated with MPA for 24 and 36 hours. Immunoprecipitation was used to examine physical interactions between RhoGDI-α and Rac1. Activation and immunoprecipitation assays showed expressions of Rac1 and RhoGDI-α to be directly correlated. Rac1 binding to RhoGDI-α decreased after MPA treatment, and Rac1 was induced and subsequently activated by MPA. We concluded that this novel RhoGDI-α/Rac1/JNK pathway induced apoptosis of transplanted islet cells after MPA treatment.

Evaluation of cell population data on the UniCel DxH 800 Coulter Cellular Analysis system as a screening for viral infection in children.

INTRODUCTION: The utility of WBC cell population data (CPD) for the differential diagnosis of viral infection from normal control, bacterial infection, and tuberculosis in children was investigated. METHODS: A data set of 602 total whole-blood samples were analyzed on the DxH 800 System for complete blood cell count (CBC) with leukocyte differential from children with the following sample breakdown: 77 confirmed diagnoses of viral infections (Epstein-Barr virus; 30, influenza A; 19, rota virus; 11, other viruses;17), 54 normal control, 71 bacterial infection, 17 TB patients, and 383 with various diseases. The mean (MN) and standard deviation (SD) of the volume (V), conductivity (C), five light-scatter measurements, and 14 calculated parameters were obtained for the leukocytes. RESULTS: Using a combination of the CBC and CPD parameter values, a decision rule, composed of 21 parameters, for the screening of viral infection in children was developed. Using this decision rule, 74 of 77 (96.1%) viral infections, two of 54 (3.7%) normal samples, one of 17 (5.9%) TB, and six of 71 (8.5%) bacterial infection samples were identified. The sensitivity was 96.1%, and specificity for normal control was 96.3% with an overall specificity of 93.7%. Fifty-nine samples of 383 samples (15.4%) collected from in-patient children with various diseases without confirmation of viral infection were included in this decision rule. CONCLUSION: In conclusion, the implementation of leukocytes CPD parameters can be useful in the detection of viral infection in children.

Screening of sepsis using leukocyte cell population data from the Coulter automatic blood cell analyzer DxH800.

INTRODUCTION: We determined the utility of leukocyte cell population data (CPD) for the screening of sepsis and fungemia. METHODS: Blood culture-positive CBC samples, 117 bacteremia and 27 fungemia, and 134 CBC samples from healthy controls were analyzed using the DxH800 and CPD of neutrophils, lymphocytes, and monocytes were analyzed. Immature granulocytes (IG) were counted using Sysmex XE-2100. RESULTS: The neutrophils and monocytes volume were increased significantly, and the neutrophils light scattering values were reduced significantly in the sepsis samples. ROC curves evidenced excellent sensitivity in the lymphocyte SD parameters (sensitivity 78-89%, specificity 78-87%), monocytes volume (at 177.5, sensitivity 88.2% specificity 87.3%), and monocytes volume SD (at 22.16, sensitivity 93.1% specificity 91.0%) for sepsis. The IG value was significantly higher in sepsis and the ROC curve evidenced a sensitivity of 82.8% and a specificity of 90.8% for sepsis. Only lower angle light scatter of lymphocytes SD value evidenced good sensitivity and specificity in the discrimination of fungemia from bacteremia (sensitivity 74.1%, specificity 72.4% at 12.6). CONCLUSION: Many of the leukocyte CPD have been identified as useful parameters of sepsis. Hopefully, these parameters can ultimately be incorporated into a decision rule for the screening of sepsis samples and to discriminate fungemia from bacteremia.
