Article Synopsis
  • * Women with HF-CS tend to be older, have fewer prior heart issues, and lower rates of severe heart dysfunction compared to men, yet both genders received similar treatments.
  • * Despite ranking equally in treatment use, the 30-day mortality rates were also comparable between sexes (around 53% for women and 51% for men), suggesting the need for further investigation into sex-specific treatment strategies.

Catheter-based revascularization procedures were developed as an alternative to systemic thrombolysis for patients with intermediate-high- and high-risk pulmonary embolisms. USAT IH-PE is a retrospective and prospective multicenter registry of such patients treated with ultrasound-facilitated, catheter-directed thrombolysis, whose preliminary results are presented in this study. The primary endpoint was the incidence of pulmonary hypertension (PH) at follow-up.

Cardiogenic shock (CS) portends a dismal prognosis if hypoperfusion triggers uncontrolled inflammatory and metabolic derangements. We sought to investigate metabolomic profiles and temporal changes in IL6, Ang-2, and markers of glycocalyx perturbation from admission to discharge in eighteen patients with heart failure complicated by CS (HF-CS). Biological samples were collected from 18 consecutive HF-CS patients at admission (T0), 48 h after admission (T1), and at discharge (T2).

Article Synopsis
  • Researchers studied the use of mechanical circulatory support (MCS) in patients with non-ischaemic cardiogenic shock (CS), focusing on how left ventricular ejection fraction (LVEF) could influence patient outcomes.
  • An analysis of 807 patients showed that while lower LVEF was linked to more severe shock, it didn't correlate with overall 30-day mortality risk; however, MCS appeared to reduce mortality in those with severely reduced LVEF (≤20%).
  • The study suggests that incorporating LVEF into decision-making for MCS in non-ischaemic CS patients could improve patient outcomes by optimizing the benefit-risk ratio.

Article Synopsis
  • - The study aimed to compare clinical characteristics and 30-day mortality rates between patients with de novo heart failure-related cardiogenic shock (HF-CS) and those with acute-on-chronic HF-CS, finding significant differences in outcomes.
  • - An analysis of 1,030 patients revealed that while traditional markers of severity were similar, acute-on-chronic HF-CS was linked to higher mortality rates (55.9% vs. 45.5%) and greater severity of shock.
  • - The results suggest that the chronicity of heart failure significantly influences the severity of cardiogenic shock, underlining the need to consider this factor in future clinical trials.

Article Synopsis
  • The analysis from the Altshock-2 registry aimed to compare the clinical features and management of cardiogenic shock due to acutely decompensated heart failure (ADHF-CS) versus that caused by acute myocardial infarction (AMI-CS).
  • It found that patients with ADHF-CS were younger but had worse kidney and liver function, leading to longer hospital stays and increased use of heart replacement therapies.
  • In terms of treatment, norepinephrine was more common for AMI-CS, while epinephrine was more frequently used for ADHF-CS, and overall in-hospital mortality rates were similar between the two groups.

Aims: Despite its high incidence and mortality risk, there is no evidence-based treatment for non-ischaemic cardiogenic shock (CS). The aim of this study was to evaluate the use of mechanical circulatory support (MCS) for non-ischaemic CS treatment.

Methods And Results: In this multicentre, international, retrospective study, data from 890 patients with non-ischaemic CS, defined as CS due to severe de-novo or acute-on-chronic heart failure with no need for urgent revascularization, treated with or without active MCS, were collected.

The performance of zeolitic imidazolate frameworks (ZIFs) as protective hosts for proteins in drug delivery or biocatalysis strongly depends on the type of crystalline phase used for the encapsulation of the biomacromolecule (biomacromolecule@ZIF). Therefore, quantifying the different crystal phases and the amount of amorphous content of ZIFs is becoming increasingly important for a better understanding of the structure-property relationship. Typically, crystalline ZIF phases are qualitatively identified from diffraction patterns.

Cardiogenic shock remains a deadly complication of acute on chronic decompensated heart failure (ADHF-CS). Despite its increasing prevalence, it is incompletely understood and therefore often misdiagnosed in the early phase. Precise diagnosis of the underlying cause of CS is fundamental for undertaking the correct therapeutic strategy.

Out-of-hospital cardiac arrest (OHCA) is still associated with high mortality and severe complications, despite major treatment advances in this field. Ischemic heart disease is a common cause of OHCA, and current guidelines clearly recommend performing immediate coronary angiography (CAG) in patients whose post-resuscitation electrocardiogram shows ST-segment elevation (STE). Contrarily, the optimal approach and the advantage of early revascularization in cases of no STE is less clear, and decisions are often based on the individual experience of the center.

Tachycardia and rapid tachyarrhythmias are common in acute clinical settings and may hasten the deterioration of haemodynamics in patients with acute decompensated heart failure (ADHF), treated with inotropes. The concomitant use of a short-acting β1-selective beta-blocker, such as landiolol, could rapidly and safely restore an adequate heart rate without any negative inotropic effect. We present a case series of five patients with left ventricular dysfunction, admitted to our Intensive Cardiac Care Unit with ADHF deteriorated to cardiogenic shock, treated with a combination of landiolol and inotropes.

Background: Acute decompensated heart failure (ADHF) complicated by cardiogenic shock (CS) has unique pathophysiological background requiring specific patient stratification, management and therapeutic targets. Accordingly, the aim of this study was to derive a simple stratification tool to predict survival in patients with ADHF complicated by CS.

Methods And Results: Using logistic regression, univariable testing was performed to identify the variables potentially associated with 28-day mortality.

Introduction: Heart failure (HF) constitutes a growing public health problem in aging societies: when pharmacological therapies fail, HF can be sustained intensively if patients are eligible for either orthotopic heart transplantation (OHT) or mechanical ventricular assistance, otherwise additional treatments could be inappropriate. In December 2017 Italian Legislator brought in the provisions regarding the end-of-life choices, including indications for withdrawing and withholding life-sustaining therapies. The aim of our study was to provide an overview of the daily practice of our center with regard to terminally ill HF patients.

MicroRNAs are tiny but powerful regulators of gene expression at the post-transcriptional level. Aberrant expression of oncogenic and tumor-suppressor microRNAs has been recognized as a common feature of human cancers. Colorectal cancer represents a major clinical challenge in the developed world and the design of innovative therapeutic approaches relies on the identification of novel biological targets.

Biocomposites composed of Zeolitic Imidazolate Frameworks (ZIFs) are generating significant interest due to their facile synthesis, and capacity to protect proteins from harsh environments. Here we systematically varied the composition ( relative amounts of ligand (2-methylimidazole), metal precursor (Zn(OAc)·2HO), and protein) and post synthetic treatments ( washes with water or water/ethanol) to prepare a series of protein@ZIF biocomposites. These data were used to construct two ternary phase diagrams that showed the synthesis conditions employed gave rise to five different phases including, for the first time, biocomposites based on ZIF-CO-1.

We have identified 24 molecular markers, based on circulating nucleic acids (CNA) originating from the human genome, which in combination can be used in a quantitative real-time PCR (qPCR) assay to identify the presence of human sepsis, starting two to three days before the first clinical signs develop and including patients who meet the SEPSIS-3 criteria. The accuracy was more than 87 % inside of the same patient cohort for which the markers were developed and up to 81 % in blind studies of patient cohorts which were not included in the marker development. As our markers are host-based, they can be used to capture bacterial as well as fungal sepsis, unlike the current PCR-based tests, which require species-specific primer sets for each organism causing human sepsis.

A library of hybrid and dimer compounds based on the natural scaffold of artemisinin was synthesized. These derivatives were obtained by coupling of artemisinin derivatives, artesunate, and dihydroartemisinin with a panel of phytochemical compounds. The novel artemisinin-based hybrids and dimers were evaluated for their anticancer activity on a cervical cancer cell line (HeLa) and on three complementary metastatic melanoma cancer cell lines (SK-MEL3, SK-MEL24, and RPMI-7951).

In the last decades, the role of the microenvironment in tumor progression and therapeutic outcome has gained increasing attention. Cancer-associated fibroblasts (CAFs) have emerged as key players among stromal cells, owing to their abundance in most solid tumors and their diverse tumor-restraining/promoting roles. The interplay between tumor cells and neighboring CAFs takes place by both paracrine signals (cytokines, exosomes and metabolites) or by the multifaceted functions of the surrounding extracellular matrix.

In the last few years, non-coding RNAs (ncRNAs) have been a hot topic in cancer research. Many ncRNAs were found to regulate the apoptotic process and to play a role in tumor cell resistance to treatment. The apoptotic program is on the frontline as self-defense from cancer onset, and evasion of apoptosis has been classified as one of the hallmarks of cancer responsible for therapy failure.
