Resistance of cancer to therapy is the main challenge to its therapeutic management and is still an unsolved problem. Rearranged lipid metabolism is a strategy adopted by cancer cells to counteract adversity during their evolution toward aggressiveness and immune evasion. This relies on several mechanisms, ranging from altered metabolic pathways within cancer cells to evolved dynamic crosstalk between cancer cells and the tumor microenvironment (TME), with some cell populations at the forefront of metabolic reprogramming, thereby contributing to the resistance of the whole ecosystem during therapy.

The fact that lipoprotein(a) levels should be regarded as a causal residual risk factor in the atherosclerotic cardiovascular diseases (ASCVD) is now a no-brainer. This review article aims to summarize the latest evidence supporting the causal role of lipoprotein(a) in ASCVD and the potential strategies to reduce the lipoprotein(a) burden until clinical trial results are available. Epidemiological and genetic data demonstrate the causal link between lipoprotein(a) and increased ASCVD risk.

Introduction: One of the most common causes of bleeding during pancreaticoduodenectomy is a dissection of the pancreatic head from the superior mesenteric vein and superior mesenteric artery. Knowledge of the anatomical variants of the veins draining the proximal jejunum may allow better control of bleeding during detachment of the uncinate process and pancreatic head from the mesenteric pedicle and division of the mesopancreas. The aim of this systematic review and meta-analysis was to evaluate the anatomical variations of the first jejunal vein (FJV) and jejunal trunk (FJT).

Epicardial adipose tissue (EAT) is a fat depot located between the myocardium and the visceral layer of the epicardium, which, owing to its location, can influence surrounding tissues and can act as a local transducer of systemic inflammation. The mechanisms upon which such influence depends on are however unclear. Given the role EAT undoubtedly has in the scheme of cardiovascular diseases (CVDs), understanding the impact of its cellular components is of upmost importance.

Background: Colovesical fistulas (CVFs) pose a challenge in diverticulitis, affecting 4% to 20% of sigmoid colon cases. Complicated diverticular disease contributes significantly, accounting for 60%-70% of all CVFs. Existing studies on laparoscopic CVF management lack clarity on its effectiveness in diverticular cases compared to open surgery.

Extracellular vesicles (EVs) are membrane-bound particles released by all cells under physiological and pathological conditions. EVs constitute a potential tool to unravel cell-specific pathophysiological mechanisms at the root of disease states and retain the potential to act as biomarkers for cardiac diseases. By being able to carry bioactive cargo (such as proteins and miRNAs), EVs harness great potential as accessible "liquid biopsies", given their ability to reflect the state of their cell of origin.

Early identification of breast cancer (BC) patients at a high risk of progression may aid in therapeutic and prognostic aims. This is especially true for metastatic disease, which is responsible for most cancer-related deaths. Growing evidence indicates that the translationally controlled tumor protein (TCTP) may be a clinically relevant marker for identifying poorly differentiated aggressive BC tumors.

Background: Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of morbidity and mortality, being twofold to fourfold more common in patients with type 2 diabetes mellitus (T2DM) than in individuals without diabetes. However, despite this decade-old knowledge, the identification of a specific prognostic risk biomarker remains particularly challenging.

Methods: Taking advantage of a large sample of Caucasian patients (n = 529) with a diagnosis of T2DM followed for a median of 16.

The treatment of chronic lymphocytic leukemia (CLL) currently relies on the use of chemo-immunotherapy, Bruton's tyrosine kinase inhibitors, or BCL2 inhibitors alone or combined with an anti-CD20 monoclonal antibody. However, the availability of multiple choices for the first-line setting and a lack of direct head-to-head comparisons pose a challenge for treatment selection. To overcome these limitations, we performed a systematic review and a network meta-analysis on published randomized clinical trials performed in the first-line treatment setting of CLL.

Identified by Berg in 1963, lipoprotein(a) represents a key contemporary residual risk pathway in atherosclerotic cardiovascular disease (ASCVD) secondary prevention. Indeed, epidemiological and genetic studies have undoubtedly demonstrated that lipoprotein(a) is one of the strongest causal risk factors of ASCVD. Although a risk threshold has been set between 30 and 50 mg/dL, depending on the ethnicity, a linear risk gradient across the distribution has been demonstrated.
