Pharmacokinetic parameters of CAZ-AVI in the normal lung and in models of pneumonia: lessons for treatment optimization in critical care.

The spread of multidrug-resistant Gram-negative bacterial infections is a significant issue for worldwide public health. Gram-negative organisms regularly develop resistance to antibiotics, especially to β-lactam antimicrobials, which can drastically restrict the number of therapies. A third-generation cephalosporin and the non-β-lactam β-lactamase inhibitor avibactam, which exhibits broad-spectrum β-lactamase inhibition , are combined to form ceftazidime-avibactam (CAZ-AVI).

This study aimed to assess the prognostic role of small dense low-density lipoprotein (sdLDL) cholesterol in patients with IE and its correlation with various disease-related features.

Methods: A cohort of 198 patients with definite IE was included in this study.

Decoding Sepsis-Induced Disseminated Intravascular Coagulation: A Comprehensive Review of Existing and Emerging Therapies.

Disseminated intravascular coagulation (DIC) is a recurrent complication of sepsis. Since DIC not only promotes organ dysfunction but also represents a strong prognostic factor, it is important to diagnose DIC as early as possible. When coagulation is activated, fibrinolysis is inhibited, blood thinners are consumed, and a condition is created that promotes blood clotting, making it more difficult for the body to remove fibrin or prevent it from being deposited in the blood vessels.

Pathophysiology of Disseminated Intravascular Coagulation in Sepsis: A Clinically Focused Overview.

Sepsis is a major global health problem that results from a dysregulated and uncontrolled host response to infection, causing organ failure. Despite effective anti-infective therapy and supportive treatments, the mortality rate of sepsis remains high. Approximately 30-80% of patients with sepsis may develop disseminated intravascular coagulation (DIC), which can double the mortality rate.

Long-Term Outcome of Infective Endocarditis Involving Cardiac Implantable Electronic Devices: Impact of Comorbidities and Lead Extraction.

(1) Background: Management of cardiac implantable electronic device-related infective endocarditis (CIED-IE) hinges on complete hardware removal. We assessed whether long-term prognosis is affected by device removal, considering baseline patient comorbid conditions; (2) Methods: A total of 125 consecutive patients hospitalized for CIED-IE were included in this retrospective analysis. Outcomes were in-hospital, one-year, and long-term mortality.

Clinical Characteristics and Outcome of MDR/XDR Bacterial Infections in a Neuromuscular Semi-Intensive/Sub-Intensive Care Unit.

(1) Background: The aim of this study was to assess the clinical and microbiological characteristics of multidrug-resistant infections in a neuromuscular semi-intensive/sub-intensive care unit; (2) Methods: Retrospective analysis on data from 18 patients with NMD with proven MDRO/XDRO colonisation/infection from August 2021 to March 2022 was carried out; (3) Results: Ten patients were males (55.6%), with a median age of 54 years, and there were fourteen patients (77.8%) with amyotrophic lateral sclerosis.

Stomatal Development and Gene Expression in Rice Florets.

Stomata play a fundamental role in modulating the exchange of gases between plants and the atmosphere. These microscopic structures form in high numbers on the leaf epidermis and are also present on flowers. Although leaf stomata are well studied, little attention has been paid to the development or function of floral stomata.

Emerging Concepts on Infection of Novel Cardiac Implantable Devices.

Novel cardiac devices, including the MitraClip system, occluder devices, leadless pacemakers, and subcutaneous implantable cardioverter defibrillators (S-ICD), are mostly used in the management of patients who are at high risk for surgery and/or developing infections. Several mechanisms render most of these devices resistant to infection, including avoiding long transvenous access and novel manufacturing material. Since subjects who use these devices already endure several comorbid conditions, uncommon cases of device-associated infection could result in serious complications and increased mortality.

Stigma/Style Cell-Cycle Inhibitor 1, a Regulator of Cell Proliferation, Interacts With a Specific 14-3-3 Protein and Is Degraded During Cell Division.

The final shape and size of plant organs are determined by a network of genes that modulate cell proliferation and expansion. Among those, functions by inhibiting cell proliferation during pistil development. Alterations in expression levels can lead to remarkable stigma/style size changes.

Dissecting the correlates of N-terminal prohormone brain natriuretic peptide in acute infective endocarditis.

Purpose: To explore the prognostic value and the correlates of NT-proBNP in patients with acute infective endocarditis, a life-threatening disease, with an often unpredictable outcome given by the lack of reliable prognostic parameters.

Methods: We retrospectively studied 337 patients admitted to our centre between January 1, 2006 and September 30, 2020 with available NT-proBNP level at admission. Our analyses were performed considering NT-proBNP as both a categorical variable, using the median value as the cut-off level, and numerical variable.

Prognostic Value of Decreased High-Density Lipoprotein Cholesterol Levels in Infective Endocarditis.

(1) Background: Simple parameters to be used as early predictors of prognosis in infective endocarditis (IE) are lacking. The aim of this study was to evaluate the prognostic role of high-density-lipoprotein cholesterol (HDL-C) and also of total-cholesterol (TC), low-density-lipoprotein cholesterol (LDL-C), and triglycerides, in relation to clinical features and mortality, in IE. (2) Methods: Retrospective analysis of observational data from 127 consecutive patients with a definite diagnosis of IE between 2016 and 2019.

Upregulation of C characteristics does not consistently improve photosynthetic performance in intraspecific hybrids of a grass.

C photosynthesis is thought to have evolved via intermediate stages, with changes towards the C phenotype gradually enhancing photosynthetic performance. This hypothesis is widely supported by modelling studies, but experimental tests are missing. Mixing of C components to generate artificial intermediates can be achieved via crossing, and the grass Alloteropsis semialata represents an outstanding study system since it includes C and non-C populations.

Complicated carbapenem-resistant infections: a treatment pathway analysis in Italian sites.

Introduction: Efforts to curb a growing prevalence of carbapenem resistance are prominent worldwide and especially in countries where high levels of carbapenem resistance are reported, such as Italy. Complicated infections, including complicated urinary tract infections (cUTI), complicated intra-abdominal infections (cIAI), and hospital-acquired/ventilator-associated bacterial pneumonia (HABP/VABP), are often caused by carbapenem-resistant Gram-negative (CRGN) bacteria and as such, these infection sites and their causative bacteria are important areas of focus for healthcare practitioners seeking to follow good antimicrobial stewardship practices. The aim of this study was to assess the clinical management and associated clinical and economic outcomes of patients with cUTI, cIAI, and HABP/VABP resulting from CRGN bacteria in Italy.
