To assess the correlation between inflammatory markers (IM) and hearing loss (HL) in a large cohort of apparently healthy individuals.A cross sectional study.Tel-Aviv Medical Center (a tertiary referral center) Inflammatory Survey Participants Individuals who attended the Tel-Aviv Medical Center Inflammatory Survey (TAMCIS) for a routine annual health check.Out of 2,500 individuals included in the final study cohort, 1,170 (47.3%) had some hearing impairment. Those with a hearing loss in 1 or both ears had significantly higher levels of neutrophils, lymphocytes, neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, and red blood cell counts. There was a difference between low- and high- frequencies losses associated with the inflammatory status.IM levels were associated with the presence of a HL, supporting a link between inflammatory changes and hearing loss.

Objective: Pericardial effusion may present clinically as pleuritic chest pain, dyspnea, or hemodynamic compromise and is a frequent finding in computerized tomographic pulmonary angiography (CTPA) exams. We hypothesized that CTPA-based analysis of the cardiac chamber volumes can be used to predict the hemodynamic significance of pericardial effusion (HsPE) as compared with echocardiography. Methods: Retrospective analysis of consecutive patients who underwent CTPA and echocardiography between January 2009 and November 2017 that ruled-out acute pulmonary embolism was included. Differences in cardiac chamber volumes were investigated in correlation to echocardiographic evidence of HsPE. Results: The final cohort included 208 patients, of whom 22 (11%) were diagnosed with HsPE. The HsPE patients had much smaller right cardiac chamber volumes (Median 78.8 ml (IQR 72.4–89.1)) than patients without HsPE (Median 115.1 ml (IQR 87.4–150). A decision tree for the prediction of HsPE showed multiple cutoff values. Right atrium (RA) volume had the best accuracy (area under the curve 0.851, 95% confidence interval 0.776–0.925, p < .001) for predicting the presence of HsPE. An RA volume ≤86 ml yielded a sensitivity of 95.5%, a specificity of 64%, and a NPV of 99.2% for the presence of HsPE. Conclusion: CTPA-based volumetric information with focus on the RA volume may help predict the presence of HsPE. Advances in knowledge: Pericardial effusion is a frequent finding in CTPA exams. Our study shows that CTPA-based volumetric information can predict the presence of HsPE with RA volume as the best indicator.

Background Elevated concentrations of C-reactive protein (CRP) early after acute coronary syndrome (ACS) may reflect the magnitude of the inflammatory response to myocardial damage and are associated with worse outcome. However, the routine measurement of both CRP and cardiac troponin simultaneously in the setting of ST segment myocardial infarction (STEMI) is not used broadly. Here, we sought to identify and characterize individuals who are prone to an elevated inflammatory response following STEMI using the CRP Troponin test (CTT) and determine their short- and long-term outcome. Material and methods We retrospectively examined 1,186 patients with the diagnosis of acute STEMI, who had at least two successive measurements of combined CRP and cardiac troponin (up to 6 hours apart), all within the first 48 hours of admission. We used Chi-Square Automatic Interaction Detector (CHAID) tree analysis to determine which parameters, timing (baseline vs. serial measurements), and cut-offs should be used to predict mortality. Results Patients with high CRP concentrations (above 90th percentile, >33mg/L) had higher 30 day- and all-cause mortality rates regardless of their troponin test status (above or below 118,000 ng/L); 14.4% vs 2.7%, p Conclusions In conclusion, serial measurements of both CRP and cardiac troponin might detect patients at increased risk for short-and long-term mortality following STEMI. We suggest the future use of the combined CRP Troponin-test (CTT) as a potential early marker for inflammatory-prone patients with worse outcomes following ACS. This sub-type of patients might benefit from early anti-inflammatory therapy such as colchicine and anti-IL-1β agents. Funding Acknowledgement Type of funding sources: None.

Parasympathetic dysfunction is associated with increased risk for major adverse cardiovascular events (MACE). However, clinically validated biomarkers that reflect parasympathetic activity are not yet available. We sought to assess the ability of serum cholinesterase activity to predict long term survival in patients undergoing coronary angiography.We prospectively followed 1002 consecutive patients undergoing clinically indicated coronary angiography (acute coronary syndrome or stable angina). We measured blood acetylcholinesterase (AChE) activity using the acetylcholine analog acetylthiocholine. Mortality rates were determined up to 10 years of follow-up. We divided our cohort into 3 groups with low, intermediate and high AChE activity by a Chi-square automatic interaction detection method (CHAID).Patients with lower than cutoff levels of AChE (300 nmol/min/ml) had higher mortality rates over 10 years of follow-up, after adjusting for conventional risk factors, biomarkers, clinical indication, and use of medications (HR = 1.6, 95% CI 1.1-2.5, p = 0.02). Patients with intermediate levels of AChE (300-582 nmol/min/ml) were also at increased risk for death (HR = 1.4, 95% CI 1.1-1.9, p = 0.02). AChE was inversely correlated with C-reactive protein, troponin I, fibrinogen and neutrophil/lymphocyte ratio levels.Patients presenting for coronary angiography with low levels of serum AChE activity are at increased risk for death during long term follow-up.

Background Previously we found that cardiac chambers' volumes correlate with estimated glomerular filtration rate (eGFR) of hospitalized patients. Currently we aimed to demonstrate this relation among apparently healthy individuals. Methods Ambulatory participants who underwent electrocardiography-gated cardiac computed tomography angiography (CCTA) were included. Subjects with an eGFR Results The cohort consisted of 89 apparently healthy individuals, mostly of male gender (70%), with a mean age of 51 years and a mean eGFR of 79.5 ml/min/1.73m2. A low calcium score (≤10HU) was found in 67.4%(n = 60) of the cohort. After adjustment for baseline characteristics, renal function was associated exclusively with the volume of the left atrium (LA; b-coefficient-0.15, 95%CI -0.3- -0.01, p = .041). A 15.9% (95%CI 0.3–33.9%, p = .045) increase in LA volume index (LAVI) was found among participants with eGFR of 80–90 when compared to those with eGFR>90 ml/min/1.73m2. Participants with a low calcium score showed an increase in LAVI only when eGFR was reduced from normal (>90 ml/min/1.73m2) to 70-80 ml/min/1.73m2 (and not to 80-90 ml/min/1.73m2), revealing a percentage increase of 24.7% (95%CI 5.5–47.4%, p = .011). Conclusions Renal function is closely related to LA volume even in the absence of overt renal failure, demonstrating that minor changes in eGFR instigate an increase in volumes. Risk factors for this interaction should be identified and treated prior to the development of cardio-renal syndrome.

PURPOSE The purpose of this study was to evaluate the association between small left atria (LA) according to computed tomography pulmonary angiography (CTPA) and mortality among individuals without pulmonary embolism, and to examine which volumes begin to portend adverse outcomes. MATERIALS AND METHODS Left atrial volume indices (LAVIs) of 752 consecutive patients who underwent CTPA, in which pulmonary embolism were ruled out, were measured retrospectively using an automatic 4-chamber volumetric analysis software. Groups of 5 percentiles within the lower quartile were investigated, and the interquartile range (25th to 75th percentiles) was regarded as the control group. RESULTS Patients within the lower 25th LAVI percentiles (

The challenge of survival prediction is ubiquitous in industry and medicine. Few methods are available for survival prediction of time varying data. Here we propose a novel method for this problem, using a random forest of survival trees for left truncated and right-censored data. We demonstrated the advantage of our method on prediction of breast cancer and prostate gland cancer risk among healthy individuals by analyzing routine laboratory measurements, vital signs and age. We analyzed electronic medical records of 20,317 healthy individuals who underwent routine checkups and identified those who later developed cancer. In cross-validation, our method predicted future prostate and breast cancers six months before diagnosis with an area under the ROC curve of 0.62±0.05 and 0.6±0.03 respectively, outperforming standard random forest, Cox-regression model and a single survival tree. Our results suggest that computational analysis of data on healthy individuals can improve the detection of those at risk of future cancer development.

Background C-reactive protein (CRP) is considered a marker of inflammation. We sought to evaluate the association between CRP level and commonly use blood tests in apparently healthy population. Methods A cross-sectional study of all visits in a routine health examination center between 1/2002 and 7/2018. CRP, complete blood count and chemistry blood panel were evaluated in each visit. Visits of individuals who had CRP above the 99th percentile or use statins were excluded. Correlation between CRP and blood tests was evaluated in the whole cohort as well as in sub-populations. Results Blood parameters of 33,261 visits were included. Moderate positive correlation between CRP and white blood cells count (r = 0.269), neutrophils count (r = 0.275), triglycerides (r = 0.275), alkaline phosphatase (r = 0.221) and gamma glutamyl transpeptidase (r = 0.220) was evaluated. Correlation with triglycerides was stronger in female then in males (r = 0.38 vs. 0.25). Uric acid was positively correlated in females and males. In participants under 30 years, inverse correlation with hemoglobin, creatinine and albumin levels and positive correlation with cholesterol were documented. Conclusion Significant moderate association between CRP and several blood tests was evaluated in apparently healthy population. This information should be used for further studies of the relationship between inflammation and biological processes.

Differential diagnosis between acute viral and bacterial infection is an emerging common challenge for a physician in the emergency department. Serum C-reactive protein (CRP) is used to support diagnosis of bacterial infection, but in patients admitted with low CRP, its ability to discriminate between viral and bacterial infections is limited. We aimed to use two consecutive CRP measurements in order to improve differential diagnosis between bacterial and viral infection. A single-center retrospective cohort (n = 1629) study of adult patients admitted to the emergency department with a subsequent microbiological confirmation of either viral or bacterial infection. Trend of CRP was defined as the absolute difference between the first two measurements of CRP divided by the time between them, and we investigated the ability of this parameter to differentiate between viral and bacterial infection. In patients with relatively low initial CRP concentration (

Background Resting heart rate (RHR) is an obtainable, inexpensive, non-invasive test, readily available on any medical document. RHR has been established as a risk factor for cardiovascular morbidity, is related to other cardiovascular risk factors, and may possibly predict them. Change in RHR over time (∆RHR) has been found to be a potential predictor of mortality. Methods In this prospective study, RHR and ∆RHR were evaluated at baseline and over a period of 2.9 years during routine check-ups in 6683 subjects without known cardiovascular disease from the TAMCIS: Tel-Aviv Medical Center Inflammation Survey. Multiple linear regression analysis with three models was used to examine ∆RHR. The first model accounted for possible confounders by adjusting for age, sex and body mass index (BMI). The 2nd model included smoking status, baseline RHR, diastolic blood pressure (BP), dyslipidemia, high-density lipoprotein (HDL) and metabolic equivalents of task (MET), and in the last model the change in MET and change in BMI were added. Results RHR decreased with age, even after adjustment for sex, BMI and MET. The mean change in RHR was − 1.1 beats/min between two consecutive visits, in both men and women. This ∆RHR was strongly correlated with baseline RHR, age, initial MET, and change occurring in MET and BMI (P Conclusions Our results highlight the need for examining individual patients’ ∆RHR. Reinforcing that a positive ∆RHR is an indicator of poor adherence to a healthy lifestyle.

Aims To assess whether hospitalization may assist in correcting errors in anticoagulant therapy among patients with atrial fibrillation (AF). Methods Our cohort included patients admitted to our institution with a history of AF between 2016 and 2018. We categorized patient's treatment upon admission and discharge as lacking (no treatment despite indication), inadequate (according to individual characteristics) or adequate. We assessed adequacy of treatment upon discharge and determined factors associated with correcting admission errors. Results Of 4427 patients admitted with a history of AF, the categorization to lacking, inadequate and adequate treatment was 1746 (39.4%), 1237 (27.9%) and 1444 (32.6%) patients, respectively. Of those with inadequate treatment, the most common types of errors were direct oral anticoagulant (DOAC) underdosing (n = 578; 46.7%), vitamin-K antagonists when DOAC was indicated (n = 258; 20.9%), DOAC despite contraindication to DOAC (n = 166; 13.4%) and DOAC overdosing (n = 124; 10%). Upon discharge 688 (18.6%, out of n = 3694) corrections but also 316 (8.6%) new mistakes were found. On multivariate logistic regression, the factors associated with correction of an error on admission were hospitalization due to AF (odds ratio [OR] 2.94 [2.39-3.61]), hospitalization in the neurologic or geriatric wards (OR 2.79 [2.04-3.80]), female sex (OR 1.34 [1.10-1.63]) and a history of stroke (OR 1.47 [1.17-1.86]), while the presence of a contraindication to DOAC decreased the chance of correction (OR 0.10 [0.06-0.18]). Conclusion Hospitalization for any reason may contribute to correction of errors in AC treatment in patients with AF. Unfortunately, a significant portion of patients remains inadequately treated by both outpatient and inpatient providers.

Background Family history of heart disease (FH‐HD) is associated with an increase drisk of subsequent HD. High sensitive cardiac troponin T (hs‐cTnT) is arecognized biomarker of myocyte injury even in HD free patients. We examined the association between FH‐HD and hs‐cTnT in apparently healthy individuals. Hypothesis FH‐HD is associated with elevated hs‐cTnT in apparently healthy individuals. Methods In a cross sectional study we analyzed data of apparently healthy individuals (n=3,821) recruited for the Tel‐Aviv Medical Center Inflammation Survey (TAMCIS). Blood samples were obtained for hs‐cTnT and high sensitive CRP (hs‐CRP) among other tests. FH‐HD was defined as first degree family member with HD diagnosis and classified as premature if the diagnosis was done before the age of 55 for men or 65 for women. Results Elevated hs‐cTnT (>14 ng/L) was more common in FH‐HD of any age, and in premature FH‐HD (FH‐P‐HD) participants than in participants without FH‐HD (4.4% vs 2.0%, p3 mg/L) increased the risk for elevated hs‐cTnT (OR=3.07, p=0.036 for FH‐HD and OR=3.25, p=0.053 for FH‐P‐HD). Conclusions FH‐HD and its interaction with elevated hs‐CRP levels were significantly associated with elevated hs‐cTnT in apparently healthy individuals suggesting that an inflammatory process may be involved in this association.

Background While chronic respiratory diseases are among the leading causes of mortality and morbidity worldwide, little is known about the effect of blood eosinophil levels on lung function trajectories among healthy individuals. Methods We analyzed data of apparently healthy individuals (n=18,089) recruited for the Tel Aviv Medical Center Inflammation Survey. Blood eosinophil levels were compared between participants with normal and those with abnormal lung function. Multivariate regression was used to assess the OR of forced expiratory volume in 1 second (FEV1) deterioration according to baseline eosinophils in subjects with normal lung function (n=4,141) during a follow-up period of 4 years. Results Participants with an abnormal, as opposed to a normal, pulmonary function test (PFT) (n=1,832, 10.1%) had significantly higher eosinophil levels, expressed as a percentage or count (2.99%±2.00% compared to 2.67%±1.88% and 0.2210e3/µL±0.163/µL compared to 0.1810e3/µL±0.183/µL, respectively; P

Non-alcoholic fatty liver disease (NAFLD) affects 25% of the population worldwide, and its prevalence is anticipated to increase globally. While most NAFLD patients are asymptomatic, NAFLD may progress to fibrosis, cirrhosis, cardiovascular disease, and diabetes. Research reports, with daunting results, show the challenge that NAFLD's burden causes to global population health. The current process for identifying fibrosis risk levels is inefficient, expensive, does not cover all potential populations, and does not identify the risk in time. Instead of invasive liver biopsies, we implemented a non-invasive fibrosis assessment process calculated from clinical data (accessed via EMRs/EHRs). We stratified patients' risks for fibrosis from 2007 to 2017 by modeling the risk in 5579 individuals. The process involved time-series machine learning models (Hidden Markov Models and Group-Based Trajectory Models) profiled fibrosis risk by modeling patients' latent medical status resulted in three groups. The high-risk group had abnormal lab test values and a higher prevalence of chronic conditions. This study can help overcome the inefficient, traditional process of detecting fibrosis via biopsies (that are also medically unfeasible due to their invasive nature, the medical resources involved, and costs) at early stages. Thus longitudinal risk assessment may be used to make population-specific medical recommendations targeting early detection of high risk patients, to avoid the development of fibrosis disease and its complications as well as decrease healthcare costs.

AIM Increased ratio between the right and left ventricular (RV/LV) diameters ≥1 is considered an important imaging marker for risk stratification among patients diagnosed with acute pulmonary embolism (PE). Our goal was to assess the prevalence of RV/LV≥1 among consecutive patients undergoing computed tomography pulmonary angiography, and to compare the prevalence of RV/LV≥1 between patients with and without PE. METHODS Retrospective analysis of consecutive patients who underwent computed tomography pulmonary angiography due to clinical suspicion of PE between January 1, 2014 and December 31, 2014. The axial RV/LV diameters were measured. The prevalence of RV/LV ≥1 was compared between patients with and without PE and among PE patients, between those with central versus peripheral PE. RESULTS The final cohort included 862 patients. A total of 142 (16.5%) had PE. RV/LV ≥1 was found in 553 (64.1%) of all patients, of them in 453 (63%) patients without PE and in 100 (70.4%) patients with PE (P=0.117). On multivariate analysis, PE was not significantly associated with RV/LV ≥1 (odds ratio [OR]: 1.4; 95% confidence interval [CI]: 0.9-2.1; P=0.102). There was no significant difference in the prevalence of RV/LV ≥1 among patients with central versus peripheral PE distribution (79.5% vs. 67%, P=0.101). Older age (OR: 1.03; 95% CI: 1.02-1.04; P

Elevated C-reactive protein (CRP) was shown to be associated with an increased risk for new-onset atrial fibrillation (AF) in ST elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI); however, the optimal time frame to measure CRP for risk stratification is not known.To evaluate the relation between the change in CRP over time (CRP velocity [CRPv]) and new-onset AF among STEMI patients treated with primary PCI.We included 801 STEMI patients who underwent PCI between 2007 and 2017 and had their CRP measured with a wide range assay (wr-CRP) at least twice during the 24 hours after admission. CRPv was defined as the change in wr-CRP concentration (mg/l) divided by the change in time (in hours) between the two measurements. Patient medical records were reviewed for occurrence of new-onset AF.New onset AF occurred in 45 patients (6%). Patients with new onset AF had significantly higher median CRPv (1.27 vs. 0.43 mg/l/h, P = 0.002). New-onset AF during hospitalization occurred in 3.4%, 4.5 %, and 9.1% of patients in the first, second and third CRPv tertiles, respectively (P for trend = 0.006). In a multivariable logistic regression, adjusting for clinical variables the odds ratios for new onset AF was 1.93 (95% confidence interval 1.0-3.59, P = 0.04) for patients in the third CRPv tertile.CRPv might be an independent and rapidly measurable biomarker for new-onset AF following primary PCI in STEMI patients.

Background: The human anti-IL-6 receptor antibody tocilizumab (TCZ) has been approved for the treatment of rheumatoid arthritis (RA) and giant cell arteritis (GCA). It is observed that CRP levels drop quickly after starting TCZ treatment. This may lead to misinterpretation of laboratory results when accessing the patient with infectious disease while on TCZ. We conducted this study to report cases treated with tocilizumab who developed serious infections with special reference to levels of CRP and to review the literature on the effect of tocilizumab on acute phase response (APR) during infections. Methods: The files of RA and GCA patients hospitalized in the Tel Aviv medical center between 2009–2019 were reviewed. Cases of patients with RA and GCA treated with tocilizumab who were hospitalized due to severe infections were reviewed with special emphasis on the duration of treatment, type of infection, and APR. Results: We identified nine admissions. Seven patients were treated with tocilizumab for RA, two for GCA. The diagnosis was pneumonia in three cases, osteomyelitis in one, cellulitis in one, endocarditis due to Whipple disease in one, abscess of cervix uteri in one, meningitis in one, and perforated diverticulitis in one. The mean CRP levels on admission were 4.75 mg/L (normal range, up to 5 mg/L). All cases were diagnosed correctly on admission. Conclusions: CRP levels may not correctly reflect the severity of infectious diseases during tocilizumab treatment. Increased awareness of the masking effect of tocilizumab on the APR during infection is needed in order to avoid a delay in the diagnosis.

Background: Patients who are admitted to the Department of Internal Medicine with apparently normal C-reactive protein (CRP) concentration impose a special challenge due the assumption that they might not harbor a severe and potentially lethal medical condition. Methods: A retrospective cohort of all patients who were admitted to the Department of Internal Medicine with a CRP concentration of ≤31.9 mg/L and had a second CRP test obtained within the next 24 h. Seven day mortality data were analyzed. Results: Overall, 3504 patients were analyzed with a mean first and second CRP of 8.8 (8.5) and 14.6 (21.6) mg/L, respectively. The seven day mortality increased from 1.8% in the first quartile of the first CRP to 7.5% in the fourth quartile of the first CRP (p < 0.0001) and from 0.6% in the first quartile of the second CRP to 9.5% in the fourth quartile of the second CRP test (p < 0.0001), suggesting a clear relation between the admission CRP and in hospital seven day mortality. Conclusions: An association exists between the quartiles of CRP and 7-day mortality as well as sepsis related cause of death. Furthermore, the CRP values 24 h after hospital admission improved the discrimination.

ObjectiveTo predict breast cancer (BC) and prostate gland cancer (PGC) risk among healthy individuals by analyzing routine laboratory measurements, vital signs and age.Materials and MethodsWe analyzed electronic medical records of 20,317 healthy individuals who underwent routine checkups, encompassing more than 600 parameters per visit, and identified those who later developed cancer. We developed a novel ensemble method for risk prediction of multivariate time series data using a random forest model of survival trees for left truncated and right-censored data.ResultsUsing cross-validation, our method predicted future PGC and BC 6 months before diagnosis, achieving an area under the ROC curve of 0.62±0.05 and 0.6±0.03 respectively, better than standard random forest, Cox-regression model and a single survival tree. Our method can complement existing screening tests such as clinical breast examination and mammography for BC, and help in detection of subjects that were missed by these tests.DiscussionComputational analysis of results of routine checkups of healthy individuals can improve the detection of those at risk of cancer development.ConclusionOur method may assist in early detection of breast and prostate gland cancer.

Atherosclerotic patients challenge the anesthesiologist as they display a significant instability between the two parts of the autonomic nervous system. We aimed to assess the effect of general anesthesia (GA) and surgery on serum cholinesterase activity. Prospective study of 57 patients undergoing ambulatory or vascular surgery under GA. Cholinesterase levels were measured before induction of anesthesia, 15 minutes thereafter and at the end of surgery by measuring the capacity of serum Acetylcholinesterase (AChE) and Butyrylcholinesterase to hydrolyze AcetylThioCholine. Data of atherosclerotic disease, anesthesia management were analyzed.Both AChE and total Cholinergic Status (CS) decreased significantly after GA induction at 15 minutes and furthermore by the end of surgery. Vascular surgery patients, presented lower baseline cholinesterase activity compared to patients for ambulatory surgery. In patients requiring intraoperative administration of phenylephrine for hemodynamic support (21.1%), a significant lower level of AChE and CS was observed compared to untreated patients. A positive correlation was found between the lowest temperatures measured and the AChE and CS change from the baseline values. Our findings serve as a mirror to the sympathetic/parasympathetic disbalance during GA with a marked decrease in the parasympathetic tone. Our data show that low cholinesterase activity increase the need for hemodynamic support.

Pulmonary hypertension (PH) is often diagnosed late in the disease course. As many patients may undergo computed tomography pulmonary angiography (CTPA) for exclusion of pulmonary embolism (PE), we aimed to create a model that can detect the existence of PH and grade its severity. Consecutive patients who underwent CTPA which was negative for PE, and echocardiography study within 24 h, were included. The CT parameters evaluated to assess PH were: the diameters of the main pulmonary artery (MPA), ascending aorta (AA), calculation of each heart chamber volume, and the severity of reflux of contrast material. Randomly, 70% of patients were included in the model creation group, and 30% were used to validate the model. The final study group included 740 patients, 268 male patients, median age 72 years. 374 patients (51%) had PH, of them 94 (13%) had severe PH on the echocardiography. Right atrium (RA) and Left atrium (LA) volume indices were the strongest parameter to indicate PH (area under the curve, AUC = 0.738 and 0.736, respectively), while Right ventricle (RV) and RA volume indices were the strongest parameter to identify severe PH (AUC = 0.735 and 0.715, respectively) with MPA diameter being the least influential indicator (AUC = 0.623). Using the patients age, gender, and multiple CTPA parameters, we created a model for predicting the existence of severe PH. After validation, the model demonstrated 91% sensitivity and a negative predictive value of 97%. Applying our models, CTPA can be used to identify severe PH immediately after the completion of CTPA exam.

Acute pulmonary embolism (PE) is considered to be one of the most common cardiovascular diseases with considerable mortality. Conflicting data imply possible role for echocardiography in assessing this disease.To determine which of the echo parameters best predicts short-term and long-term mortality in patients with PE.We prospectively enrolled 235 patients who underwent computed tomography of pulmonary arteries (CTPA) and transthoracic Echocardiography (TTE) within24 hours. TTE included a prospectively designed detailed evaluation of the right heart including right ventricular (RV) myocardial performance index (RIMP), RV end diastolic and end systolic area, RV fractional area change, acceleration time (AT) of pulmonary flow and visual estimation. Interpretation and performance of TTE were blinded to the CTPA results.Although multiple TTE parameters were associated with PE, all had low discriminative capacity (AUC0.7). Parameters associated with 30-day mortality in univariate analysis were acceleration time (AT)81 msec (P = 0.04), stroke volume44 cc (P = 0.005), and RIMP0.42 (P = 0.05). The only RV independent echo parameter associated with poor long-term prognosis (adjusted for significant clinical, and routine echo associates of mortality) was RIMP (hazard ratio 3.0, P = 0.04). The only independent RV echo parameters associated with mortality in PE patients were RIMP (P = 0.05) and AT (P = 0.05). Addition of RIMP to nested models eliminated the significance of all other parameters assessing RV function.Doppler-based parameters like pulmonary flow AT, RIMP, and stroke volume, have additive value in addition to visual RV estimation to assess prognosis in patients with PE.

A first C-reactive protein (CRP) test, as often performed by clinicians during the presentation of patients with an acute bacterial infection, might be misleading. The aim of our study was to explore the dynamic between a second CRP test taken within 12 hours from admission CRP test in a cohort of patients diagnosed with acute bacterial infection in comparison to CRP in a control group of apparently healthy individuals. This was a historical cohort study comprised of all patients admitted to the Sourasky Tel-Aviv Medical Center, Israel, between July 2007 and March 2016. The study cohort included adult patients who were diagnosed as having an infection, assumed to be of bacterial etiology (cellulitis and erysipelas, pneumonia, cholecystitis, pyelonephritis, or septicemia), who had a CRP test during the first 6 hours of hospital admission (baseline CRP), and a successive CRP test up to 12 hours from the first one (recurrent CRP). The control group was of healthy subjects who attended our medical center for a routine annual check-up. The study included 950 patients. Baseline CRP ranged from 0.04 to 454 mg/L. The median CRP velocity was 0.53 mg/L/h. Patients were grouped by baseline CRP into 4 groups (CRP

The presence of a microinflammatory response is one of the possible pathological mechanisms related to the development of nonarteritic anterior ischemic optic neuropathy (NAAION), a common cause of optic neuropathy in old age.We tested whether individuals with NAAION harbor a heightened microinflammatory response compared to controls.We measured the erythrocyte sedimentation rate (ESR) and high sensitivity C-reactive protein (hs-CRP) in NAAION patients during hospital admission and in four matched controls for each patient, retrieved from a large cohort of 20,000 apparently healthy individuals.We included 128 NAAION patients and 512 controls. No significant differences were found between patients and controls regarding the inflammatory biomarkers.This is the first report showing a lack of difference in ESR and hs-CRP levels between NAAION patients and matched controls, suggesting NAAION is not associated with a heightened inflammatory response, such as the one associated with multiple atherothrombotic risk factors.

Detection of an eventful course in the early days of sepsis treatment is clinically relevant. The white blood cell count (WBCC) and C-reactive protein (CRP) are used in daily practice to monitor the intensity of the inflammatory response associated with sepsis. It is not entirely clear which of the two might better discriminate the outcomes of patients with sepsis.30-day mortality was assessed in a cohort of patients who were hospitalized with sepsis in the departments of Internal Medicine in a tertiary medical center. Admission and 72-hour time points were analyzed to discriminate between patients with increased versus decreased 30 days mortality risk.The study included 195 patients. Higher 72 h CRP, WBCC, neutrophil counts and neutrophils to lymphocyte ratio were associated with increased mortality (p 0.02). Baseline WBCC and CRP failed to discriminate between patients who died and those who survived (AUC = 0.551, 0.479). In multivariate analysis of the 72 h tests, higher WBCC count (OR = 1.12, 95%CI 1.05-1.20, p = 0.001), was associated with increased mortality whereas CRP was not (OR = 1.004, 95%CI 0.998-1.01, p = 0.146).Patients who presented a 72-hour leukocyte descent had a better outcome and in this regard, WBCC was superior to 72-hour CRP in predicting 30 days mortality.
