Similar Outcomes in Males and Females Undergoing Surgery for Infective Endocarditis.

: Sex-based differences in mortality have been previously observed in patients with surgically treated infective endocarditis. We sought to evaluate the risk factors leading to this difference. : A retrospective cohort from three centers in Israel comprising 376 surgically treated patients, comparing short- and long-term mortality rates and risk factors between female and male patients.

Intravenous iron administration before cardiac surgery reduces red blood cell transfusion in patients without anaemia.

Background: Reducing the need for blood transfusion among patients undergoing cardiac surgery FLA reduce postoperative complications and mortality. Our study aimed to assess the effects of administering preoperative i.v.

High sensitivity troponin-I threshold to predict perioperative myocardial infarction.

Background: High-sensitivity Troponin I (hs-cTnI) has largely replaced conventional troponin assays in an effort to improve detection of myocardial infarction. However, the mean displacement of hs-cTnI following coronary artery bypass graft (CABG) and the optimal threshold to detect perioperative myocardial infarction (MI) is unclear. Our objective is to describe mean hs-cTnI values at 6-12 h post-CABG and to determine the highest specificity while maintaining 100% sensitivity hs-cTnI cut-off values for diagnosis of perioperative or type-5 MI.

The diagnostic value of nasal microbiota and clinical parameters in a multi-parametric prediction model to differentiate bacterial versus viral infections in lower respiratory tract infections.

Background: The ability to accurately distinguish bacterial from viral infection would help clinicians better target antimicrobial therapy during suspected lower respiratory tract infections (LRTI). Although technological developments make it feasible to rapidly generate patient-specific microbiota profiles, evidence is required to show the clinical value of using microbiota data for infection diagnosis. In this study, we investigated whether adding nasal cavity microbiota profiles to readily available clinical information could improve machine learning classifiers to distinguish bacterial from viral infection in patients with LRTI.

Midterm Results of Isolated Tricuspid Valve Replacement-Implications for Clinical Decision Making.

Background: Isolated tricuspid valve replacement (TVR) is considered high-risk surgery. We investigated our outcomes of TVR with the aim of identifying variables that may influence morbidity and mortality of isolated TVR compared with combined TVR and left-sided valve surgery.

Methods: Retrospective analysis of patients undergoing TVR surgery.

ATF3 expression in cardiomyocytes and myofibroblasts following transverse aortic constriction displays distinct phenotypes.

Background: Activating transcription 3 (ATF3) is a member of the basic leucine zipper family of transcription factors. ATF3 is an immediate early gene expressed following various cellular stresses. ATF3 acts through binding to cyclic AMP response elements found in the promoters of key regulatory proteins that determine cell fate.

Early Cardiac Remodeling Promotes Tumor Growth and Metastasis.

Background: Recent evidence suggests that cancer and cardiovascular diseases are associated. Chemotherapy drugs are known to result in cardiotoxicity, and studies have shown that heart failure and stress correlate with poor cancer prognosis. However, whether cardiac remodeling in the absence of heart failure is sufficient to promote cancer is unknown.

JDP2 and ATF3 deficiencies dampen maladaptive cardiac remodeling and preserve cardiac function.

c-Jun dimerization protein (JDP2) and Activating Transcription Factor 3 (ATF3) are closely related basic leucine zipper proteins. Transgenic mice with cardiac expression of either JDP2 or ATF3 showed maladaptive remodeling and cardiac dysfunction. Surprisingly, JDP2 knockout (KO) did not protect the heart following transverse aortic constriction (TAC).

Antibiotic misuse in respiratory tract infections in children and adults-a prospective, multicentre study (TAILORED Treatment).

Respiratory tract infections (RTI) are more commonly caused by viral pathogens in children than in adults. Surprisingly, little is known about antibiotic use in children as compared to adults with RTI. This prospective study aimed to determine antibiotic misuse in children and adults with RTI, using an expert panel reference standard, in order to prioritise the target age population for antibiotic stewardship interventions.

A host-protein signature is superior to other biomarkers for differentiating between bacterial and viral disease in patients with respiratory infection and fever without source: a prospective observational study.

Bacterial and viral infections often present with similar symptoms. Etiologic misdiagnosis can alter the trajectory of patient care, including antibiotic overuse. A host-protein signature comprising tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), interferon gamma-induced protein-10 (IP-10), and C-reactive protein (CRP) was validated recently for differentiating bacterial from viral disease.

A novel host-protein assay outperforms routine parameters for distinguishing between bacterial and viral lower respiratory tract infections.

Bacterial and viral lower respiratory tract infections (LRTIs) are often clinically indistinguishable, leading to antibiotic overuse. We compared the diagnostic accuracy of a new assay that combines 3 host-biomarkers (TRAIL, IP-10, CRP) with parameters in routine use to distinguish bacterial from viral LRTIs. Study cohort included 184 potentially eligible pediatric and adult patients.

causing life-threatening disease in a susceptible patient.

A 56-year-old man with lymphoma developed orchitis followed by septic arthritis of his right glenohumeral joint. Synovial fluid cultures were negative but PCR amplification test was positive for The patient was treated with doxycycline. Two and a half years later, the patient presented with shortness of breath and grade III/IV diastolic murmur on auscultation.

Emboli and cognitive state in surgical vs. transcatheter aortic valve replacement.

Background Neurologic complications and neurocognitive impairment due to cerebral emboli are common following heart surgery. This study aimed to compare the number of emboli detected in the middle cerebral artery in open aortic valve replacement, apical and femoral transcatheter aortic valve replacement, and also to test for an association between the number of emboli captured in each procedure and changes in the patient's cognitive state. Methods Forty-four patients were enrolled in the study, 36 of whom were included in the final analyses: 14 underwent open aortic valve replacement, 2 had femoral transcatheter aortic valve replacement, and 10 had apical transcatheter aortic valve replacement.

A novel host-proteome signature for distinguishing between acute bacterial and viral infections.

Bacterial and viral infections are often clinically indistinguishable, leading to inappropriate patient management and antibiotic misuse. Bacterial-induced host proteins such as procalcitonin, C-reactive protein (CRP), and Interleukin-6, are routinely used to support diagnosis of infection. However, their performance is negatively affected by inter-patient variability, including time from symptom onset, clinical syndrome, and pathogens.
