Chronic kidney disease (CKD) and heart failure (HF) are interrelated conditions that exacerbate each other through mechanisms like fluid retention, neurohormonal activation, and inflammation. Red blood cell distribution width (RDW), a measure of red blood cell size variability, has emerged as a potential prognostic marker in HF. This study aimed to assess the prognostic value of RDW in HF patients, both with and without CKD, focusing on all-cause mortality and HF rehospitalizations.

A thorough literature search was conducted on patients with Left Ventricular Assist Device (LVAD) and aortic insufficiency undergoing transcatheter aortic valve replacement (TAVR). We identified all original research studies that compared the long-term outcomes of surgical transcatheter aortic valve replacement (SAVR) versus TAVR for patients with LVAD, published between 1990 and 2023. The primary endpoint was the composite of in-hospital mortality, stroke, transient ischemic attack, myocardial infarction (MI), pacemaker implantation, vascular complications and cardiac tamponade.

Objective: We reviewed the available literature on patients undergoing aortic repair for acute type A aortic dissection (ATAAD) with either aortic root preservation (RP) or root replacement (RR).

Methods: Original research studies that evaluated short- and mid-term hemostatic properties of RP versus RR groups were identified, from 2000 to 2024. Intraoperative transfusions of red blood cells (RBCs), reoperation for bleeding, strategy of hemostatic sealing of the anastomosis in root repair following the reapproximation of the dissected layers of the aortic wall (with/without biological glue), and operative mortality were the primary endpoints.

Article Synopsis
  • The study investigated how preoperative quality of life scores (EORTC QLQ-C30) relate to metrics like age and BMI in elderly patients undergoing colorectal cancer surgery.
  • It included 118 patients over 65 with resectable cancer, revealing negative correlations between QLQ scores and age, as well as differences in scores based on the type of cancer (rectal vs colon).
  • The findings suggest that lower preoperative QLQ scores are linked to longer recovery times and complications, indicating that these scores can predict postoperative outcomes in older patients.

Chest radiography, computed tomography (CT) and positron emission tomography (PET)-CT are required for staging nonsmall cell lung cancers. Stage I cancers may be up to 4 cm in maximal diameter, with stage IA tumours being up to 3 cm and stage IB up to 4 cm. A lung cancer becomes stage II if the tumour is between 4 and ≤5 cm (stage IIA), or it spreads to ipsilateral peribronchial or hilar lymph nodes (stage IIB).

Article Synopsis
  • Cardiac amyloidosis is a serious condition where abnormal amyloid fibrils accumulate in the heart, causing it to function poorly. It's mainly classified into two types: immunoglobulin light chain amyloidosis and transthyretin amyloidosis (ATTR), which comes in non-hereditary and hereditary forms.
  • The rise in cases of ATTR cardiac amyloidosis is partly due to better diagnostic methods, and survival rates are improving thanks to new treatment options like tafamidis and emerging therapies currently in trials.
  • New treatments such as acoramidis, eplontersen, vutrisiran, patisiran, and an experimental antibody NI006 are being tested to enhance cardiac function, with results expected in a few

The frozen elephant trunk (FET) technique is increasingly utilized for aortic arch replacement in cases of aortic dissections and aneurysms. This rise in usage has led to more patients needing redo aortic surgeries due to progression of existing conditions, FET-related complications, or new valvular/coronary diseases. This article aims to evaluate surgical techniques to minimize risks during these reoperations, including a case study of a complex redo surgery.

Background: This meta-analysis and systematic review aim to consolidate evidence on cardiotoxicity prevention and treatment strategies in patients receiving anthracyclines or HER2 receptor inhibitors, vital treatments for breast cancer and hematologic malignancies. By synthesizing existing research, the goal is to provide impactful insights that enhance patient care and outcomes.

Methods: Comprehensive research across PubMed, Scopus, EMBASE, and the Cochrane Central Register for Controlled Trials was conducted, selecting clinical trials focusing on cardioprotection in anthracyclines or HER2 inhibitor-treated individuals.

Background: We aim to provide a comprehensive review of the current state of knowledge of myocardial viability assessment in patients undergoing coronary artery bypass grafting (CABG), with a focus on the clinical markers of viability for each imaging modality. We also compare mortality between patients with viable myocardium and those without viability who undergo CABG.

Methods: A systematic database search with meta-analysis was conducted of comparative original articles (both observations and randomized controlled studies) of patients undergoing CABG with either viable or nonviable myocardium, in EMBASE, MEDLINE, Cochrane database, and Google Scholar, from inception to 2022.

: The aim of this study was to examine the association between in-hospital initiation of sodium glucose co-transporter 2 inhibitors (SGLT2is) and outcomes in hospitalized heart failure (HHF) patients utilizing data from a Greek center. : The present work was a single-center, retrospective, observational study of consecutive HF patients hospitalized in a tertiary center. The study endpoint was all-cause mortality or HF rehospitalization.

Hepatopancreato and biliary (HPB) tumors represent some of the leading cancer-related causes of death worldwide, with the majority of patients undergoing surgery in the context of a multimodal treatment strategy. Consequently, the implementation of an accurate risk stratification tool is crucial to facilitate informed consent, along with clinical decision making, and to compare surgical outcomes among different healthcare providers for either service evaluation or clinical audit. Perioperative troponin levels have been proposed as a feasible and easy-to-use tool in order to evaluate the risk of postoperative myocardial injury and 30-day mortality.

Indication to perform surgical explantation of TAVR is becoming increasingly more frequent, due to the higher number of transcatheter procedures performed in patients with longer life expectancy. We proposed to perform a systematic review and meta-analysis with metaregression to identify potential factors that can determine an increase in the high mortality and morbidity that characterize these surgical procedures. MEDLINE and Embase were searched for relevant studies.

Chronic heart failure (HF) is a clinical syndrome with high morbidity and mortality worldwide. Cardiac rehabilitation (CR) is a medically supervised program designed to maintain or improve cardiovascular health of people living with HF, recommended by both American and European guidelines. A CR program consists of a multispecialty group including physicians, nurses, physiotherapists, trainers, nutritionists, and psychologists with the common purpose of improving functional capacity and quality of life of chronic HF patients.

Infective endocarditis (IE) is a severe cardiac complication with high mortality rates, especially when surgical intervention is delayed or absent. This review addresses the expanding role of surgery in managing IE, focusing on the variation in surgical treatment rates, the impact of patient demographics, and the effectiveness of different surgical approaches. Despite varying global data, a notable increase in surgical interventions for IE is evident, with over 50% of patients undergoing surgery in tertiary centres.

Article Synopsis
  • Early risk stratification is crucial for hospitalized heart failure (HF) patients, and the study focused on the Larissa Heart Failure Risk Score (LHFRS) as a predictive tool.
  • Data was analyzed from over 13,000 HF admissions at the Cleveland Clinic, examining factors like hypertension history and RDW levels, to predict one-year readmission and mortality.
  • The findings showed a strong relationship between higher LHFRS values and adverse outcomes, suggesting that this simple model can effectively aid in assessing the risk for HF patients.

Objective: Thoracic aortic aneurysm dissection (TAAD) represents a cardiac surgery emergency characterized by the disrupted integrity of the aortic wall and is associated with poor prognosis. In this context, the identification of biomarkers implicated in the pathobiology of TAAD is crucial. Our aim in the present original in silico study is to assess the differential gene expression profile of the tight junction proteins (TJPs) in patients with TAAD and to propose novel biomarkers for the diagnosis and prognosis of this disease.
