#1
REVIEW
Benoit Pilmis, Vincent Jullien, Alexis Tabah, Jean-Ralph Zahar, Christian Brun-Buisson
Several studies suggest that alternatives to carbapenems, and particulary beta-lactam/beta-lactamase inhibitor combinations, can be used for therapy of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE)-related infections in non-ICU patients. Little is known concerning ICU patients in whom achieving the desired plasmatic pharmacokinetic/pharmacodynamic (PK/PD) target may be difficult. Also, in vitro susceptibility to beta-lactamase inhibitors might not translate into clinical efficacy. We reviewed the recent clinical studies examining the use of BL/BLI as alternatives to carbapenems for therapy of bloodstream infection, PK/PD data and discuss potential ecological benefit from avoiding the use of carbapenems...

BACKGROUND: Infective endocarditis (IE) is a complex disease necessitating extensive clinical guidelines. The guidelines from the American Heart Association (AHA) and the European Society of Cardiology (ESC) have been markedly extended during the last 12 years. We examined the evidence base for these changes. METHODS: IE guidelines published by AHA and ESC were reviewed. We categorized and combined guidelines into 3 time periods: (1) 2004 (AHA) and 2005 (ESC), (2) 2007 (AHA) and 2009 (ESC), and (3) 2015 (AHA) and 2015 (ESC)...

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Long term cigarette smoking is the cause of more than 90% of COPD in Westernized countries. However, only a fraction of chronic heavy smokers develop symptomatic COPD by the age of 80 years. COPD is characterized by an abnormal immune response in the lower airways and its progression is associated with infiltration of the lung by innate and adaptive inflammatory immune cells that form lymphoid follicles. There is growing evidence that both cellular- and antibody-mediated autoimmunity has a fundamental role in the pathogenesis of stable COPD...

OBJECTIVE: To develop and validate new classification criteria for adult and juvenile idiopathic inflammatory myopathies (IIM) and their major subgroups. METHODS: Candidate variables were assembled from published criteria and expert opinion using consensus methodology. Data were collected from 47 rheumatology, dermatology, neurology, and pediatric clinics worldwide. Several statistical methods were utilized to derive the classification criteria. RESULTS: Based on data from 976 IIM patients (74% adults; 26% children) and 624 non-IIM patients with mimicking conditions (82% adults; 18% children), new criteria were derived...

OBJECTIVES: To assess the contributions of cortico-juxtacortical and corpus callosum lesions to multiple sclerosis diagnosis and to compare the value of ≥1 vs ≥3 periventricular lesions in clinically isolated syndromes (CIS). METHODS: Step 1: We evaluated lesion topography classifications in 657 patients with CIS with stepwise Cox proportional hazards regression models considering second attack as the outcome. Step 2: We established 2 dissemination in space (DIS) versions according to the periventricular lesion cutoffs of ≥1 and ≥3 and assessed their performance at 10 years with second attack as the outcome, first individually and then combined with dissemination in time (DIT) in all cases (n = 326), by age, and by CIS topography...

Background: The clinical significance of urinary liver fatty acid-binding protein (u-LFABP) in acute heart failure (AHF) patients remains unclear. Methods and Results: The u-LFABP levels on admission of 293 AHF patients were analyzed. The patients were divided into 2 groups according to the u-LFABP quartiles (Q1, Q2, and Q3 = low u-LFABP [L] group vs. Q4 = high u-LFABP [H] group). We evaluated the diagnostic and prognostic value of u-LFABP and compared the findings between the chronic kidney disease (CKD; n = 165) and non-CKD patients (n = 128)...

Staphylococcus warneri, a coagulase negative staphylococcus, has been isolated in prosthetic device-related infections and has been reported as a rare cause of endocarditis. We report a case of prosthetic aortic valve S. warneri endocarditis, in which the patient lacked typical infectious signs and symptoms, instead presenting with congestive heart failure due to perforation of the valve. Providers should consider endocarditis with a low virulence pathogen such as S. warneri when a patient with a prosthetic valve presents with heart failure, even in the absence of fever, leukocytosis and other infectious symptoms...

CONTEXT: Pheochromocytoma and paraganglioma are rare neuroendocrine tumors which overproduce catecholamines and arise from the adrenal gland or extra-adrenal chromaffin cells of the sympathetic and parasympathetic ganglia (1). Excessive catecholamine-induced stimulation of cardiac myocytes leads to damage which manifests in several forms ranging from Takotsubo to dilated cardiomyopathy. Diagnosis of pheochromocytoma-related cardiomyopathies is often delayed due to the atypical presentation associated with many cases...

OBJECTIVE: Oritavancin is a lipoglycopeptide antibiotic approved for use in acute bacterial skin and skin structure infections as a single 1200 mg parenteral dose. Because of oritavancin's long half-life and broad gram-positive activity, interest in its use for other infections is high. METHODS: This study is a retrospective cohort evaluation of patients receiving oritavancin at a single academic medical center. All patients receiving more than one dose of oritavancin were included...

BACKGROUND: The incidence of C. difficile infection (CDI) and of bloodstream infection (BSI) caused by Candida spp., ESBL-E-producing Enterobacteriaceae (ESBL-E) and carbapenemase-producing K. pneumoniae (CP-Kp) is associated with high mortality. METHODS: We conducted a single centre retrospective study on patients admitted to Molinette Hospital, Turin, Italy, from January 2013 to April 2015 with CDI or BSI caused by Candida, ESBL-E or CP-Kp. For each patient demographic, clinical and microbiological data were collected...

REVIEW
Yoshiaki Takahashi, Masayuki Igarashi
Aminoglycoside antibiotics (AGAs) were developed at the dawn of the antibiotics era and have significantly aided in the treatment of infectious diseases. Aminoglycosides have become one of the four major types of antibiotics in use today and, fortunately, still have an important role in the clinical treatment of severe bacterial infections. In this review, the current usage, modes of action and side effects of AGAs, along with the most common bacterial resistance mechanisms, are outlined. Finally, the recent development situation and possibility of new AGAs in the 'post-antibiotic era' are considered...

Platelets have received increasing attention for their role in the pathophysiology of infectious disease, inflammation, and immunity. In sepsis, a low platelet count is a well-known biomarker for disease severity and more recently authors have focused their attention on the active role of platelets in the pathogenesis of multi-organ failure. Septic shock is characterised by a dysregulated inflammatory response, which can impair the microcirculation and lead to organ injury. Being at the crossroads between the immune system, clotting cascade, and endothelial cells, platelets seem to be an appealing central mediator and possible therapeutic target in sepsis...

OBJECTIVES: This study sought to investigate in the general heart failure (HF) population, whether the associations between type 2 diabetes (T2D) and risk of hospitalization and death, are modified by changing glycemic or drug treatment intensity. BACKGROUND: In the general HF population, T2D confers a higher risk of poor outcomes, but whether this risk is modified by the diabetes status is unknown. METHODS: A nested case-control study in an incident HF database cohort (2002 to 2014) comparing patients with T2D with those without, for risk of all-cause first hospitalization and death...

Diabetic cardiomyopathy is characterized by metabolic changes in the myocardium that promote a slow and silent dysfunction of muscle fibers, leading to myocardium remodelling and heart failure, independently of the presence of coronary artery diseases or hypertension. At present, no imaging methods allow an early diagnosis of this disease. Circulating miRNAs in plasma have been proposed as biomarkers in the prognosis of several cardiac diseases. This study aimed to determine whether circulating miRNAs could be potential biomarkers of diabetic cardiomyopathy...

INTRODUCTION: Elderly adults with heart failure (HF) may have problems with self-care behaviors because of cognitive deficits. Self-care deficits have been found to be significantly associated with negative health care outcomes among HF patients. The aim of this paper was to assess cognitive deficits and the level of self-care ability in elderly patients with HF, and to determine if a relationship exists between cognitive deficits and self-care. MATERIALS AND METHODS: The study included 270 elderly patients (mean age: 72...

Aims: Albuminuria-a marker of generalized vascular dysfunction-is a strong predictor of heart failure in patients with type 2 diabetes which may be caused by concomitant myocardial dysfunction reflecting the same underlying pathogenesis. Methods and results: We included 915 patients with type 2 diabetes from two secondary care centres and stratified according to albuminuria status in normo-, micro-, and macroalbuminuria. We performed comprehensive echocardiography including conventional imaging, tissue Doppler imaging, and 2D speckle tracking...
