The Impact of Liquid Biopsy in Advanced Ovarian Cancer Care.

Introduction: Ovarian cancer is the third most common gynaecological cancer and has a very high mortality rate. The cornerstone of treatment is complete debulking surgery plus chemotherapy. Even with treatment, 80% of patients have a recurrence.

Extensive folliculitis and abscesses with a sporotrichoid distribution in a parenteral drug user.

We present the case of a 53-year-old Caucasian man with a history of intravenous drug use who presented with fever and multiple pustules predominantly affecting hairy areas of the body, with no clinical improvement despite previous antibiotic treatment. Culture of the pustules confirmed Candida albicans infection and histological examination of skin biopsies revealed suppurative granulomas compatible with candidomycetic folliculitis. The patient was successfully treated with systemic antifungals and discharged with resolution of symptoms.

Evaluation of Immune Infiltrates in Ovarian Endometriosis and Endometriosis-Associated Ovarian Cancer: Relationship with Histological and Clinical Features.

Background: the association between ovarian endometriosis (OE) and endometriosis-associated ovarian cancer (EAOC) is extensively documented, and misfunction of the immune system might be involved. The primary objective of this study was to identify and compare the spatial distribution of tumour-infiltrating lymphocytes (TILs) and tumour-associated macrophages (TAMs) in OE and EAOC. Secondary objectives included the analysis of the relationship between immunosuppressive populations and T-cell exhaustion markers in both groups.

Role of Syndecans in Ovarian Cancer: New Diagnostic and Prognostic Biomarkers and Potential Therapeutic Targets.

Ovarian cancer (OC) is the eighth cancer both in prevalence and mortality in women and represents the deadliest female reproductive cancer. Due to generally vague symptoms, OC is frequently diagnosed only at a late and advanced stage, resulting in high mortality. The tumor extracellular matrix and cellular matrix receptors play a key role in the pathogenesis of tumor progression.

New Roles for Old Friends: Involvement of the Innate Immune System in Tumor Progression.

Increased levels of NETosis biomarkers in high-grade serous ovarian cancer patients' biofluids: Potential role in disease diagnosis and management.

Introduction: High-grade serous ovarian cancer (HGSOC) is the second most frequent gynecological malignancy but the most lethal, partially due to the spread of the disease through the peritoneal cavity. Recent evidence has shown that, apart from their role in immune defense through phagocytosis and degranulation, neutrophils are able to participate in cancer progression through the release of neutrophil extracellular traps (NETs) in a process called NETosis. NETs are composed of DNA, histones, calprotectin, myeloperoxidase (MPO) and elastase and the NETosis process has been proposed as a pre-requisite for the establishment of omental metastases in early stages of HGSOC.

Feasibility and safety of transvaginal specimen extraction in deep endometriosis colorectal resectional surgery and analysis of risk factors for postoperative complications.

Background: The aim of the present study was to demonstrate that transvaginal specimen extraction is a feasible and safe approach in colorectal resection for deep endometriosis (DE) and to assess the risk factors for postoperative complications.

Methods: This retrospective cohort study included all the consecutive patients undergoing segmental bowel resection for symptomatic endometriosis at "La Paz" University Hospital (Madrid, Spain) and at "Hospital General Universitario de Valencia" (Valencia, Spain) from January 2014 to December to 2017. Patients were grouped according to specimen extraction approach into those who had transvaginal extraction (Group I) and those who had suprapubic extraction (Group II).

Postoperative Intestinal Fistula in Primary Advanced Ovarian Cancer Surgery.

Background: Advanced ovarian cancer (AOC) requires an aggressive surgery with large visceral resections in order to achieve an optimal or complete cytoreduction and increase the patient's survival. However, the surgical aggressiveness in the treatment of AOC is not exempt from major complications, such as the gastrointestinal fistula (GIF), which stands out among others due to its high morbidity and mortality.

Methods: We evaluated the clinicopathological features in patients with AOC and their association with GI.

Toward an improved assessment of quality of life in endometriosis: evaluation of the Spanish version of the Endometriosis Health Profile 30.

Purpose: Our main objective is to evaluate the psychometric properties of the Spanish version of the EHP-30 questionnaire. The secondary aim is to evaluate the differences in the scores of the core EHP-30 scales between patients with either surgical treatment or conservative management of endometriosis.

Methods: Cross-sectional study conducted into a tertiary hospital endometriosis reference unit.

Micro-RNA profile and proteins in peritoneal fluid from women with endometriosis: their relationship with sterility.

Objective: To define the microRNA (miRNA) profile and its relationship with cytokines content in peritoneal fluid (PF) from endometriosis patients.

Design: Case-control study.

Setting: University hospital, research institute.

Thickness and an Altered miRNA Expression in the Epicardial Adipose Tissue Is Associated With Coronary Heart Disease in Sudden Death Victims.

Introduction And Objectives: An increased epicardial adipose tissue (EAT) thickness has become a new risk factor for coronary heart disease (CHD). We aimed to study the role of EAT dysfunction as a CHD marker by focusing on its thickness and microRNA (miRNA) expression profile, and the potential factors possibly influencing them.

Methods: One hundred and fifty-five CHD sudden cardiac death victims and 84 non-CHD-sudden death controls were prospectively enrolled at autopsy.

Translating cancer epigenomics into the clinic: focus on lung cancer.

Epigenetic deregulation is increasingly being recognized as a hallmark of cancer. Recent studies have identified many new epigenetic biomarkers, some of which are being introduced into clinical practice for diagnosis, molecular classification, prognosis or prediction of response to therapies. O-6-methylguanine-DNA methyltransferase gene is the most clinically advanced epigenetic biomarker as it predicts the response to temozolomide and carmustine in gliomas.

Deregulated hepatic microRNAs underlie the association between non-alcoholic fatty liver disease and coronary artery disease.

Background & Aims: Non-alcoholic fatty liver disease (NAFLD) appears to be a new risk factor for the development of coronary artery disease (CAD). Members of a class of non-coding RNAs, termed microRNAs (miRNAs), have been identified as post-transcriptional regulators of cholesterol homoeostasis and can contribute to the development of NAFLD. The aims of this study were to (i) to assess the relationship between NAFLD and sudden cardiac death (SCD) from severe CAD in forensic autopsies and (ii) to quantify several hepatic miRNAs previously associated with lipid metabolism and NAFLD to correlate their expression with the presence of NAFLD, CAD, obesity parameters and postmortem lipid profile.

miRNAs Regulation and Its Role as Biomarkers in Endometriosis.

MicroRNAs (miRNAs) are small non-coding RNAs (18-22 nt) that function as modulators of gene expression. Since their discovery in 1993 in C. elegans, our knowledge about their biogenesis, function, and mechanism of action has increased enormously, especially in recent years, with the development of deep-sequencing technologies.

Peritoneal fluid modifies the microRNA expression profile in endometrial and endometriotic cells from women with endometriosis.

Study Question: Could peritoneal fluid (PF) from patients with endometriosis alter the microRNA (miRNA) expression profile in endometrial and endometriotic cells from patients?

Summary Answer: PF from patients with endometriosis modifies the miRNA expression profile in endometrial cells from patients.

What Is Known Already: Angiogenesis is a pivotal system in the development of endometriosis, and dysregulated miRNA expression in this disease has been reported. However, to our knowledge, the effect of PF from patients on the miRNA expression profile of patient endometrial cells has not been reported.

MicroRNAs and angiogenesis in endometriosis.

miRNAs function as important regulators of a wide range of cellular processes, such as angiogenesis and fibrinolysis, by postranscriptional modulation of gene expression. We present a review on the role of miRNAs and angiogenesis in endometriosis. Endometriosis, defined as the implantation of endometrial tissue outside the uterine cavity, is one of the most frequent benign gynecological diseases and it has important consequences on the quality of life and fertility of patients.

MicroRNA expression profile in endometriosis: its relation to angiogenesis and fibrinolytic factors.

Study Question: Could an aberrant microRNA (miRNA) expression profile be responsible for the changes in the angiogenic and fibrinolytic states observed in endometriotic lesions?

Summary Answer: This study revealed characteristic miRNA expression profiles associated with endometriosis in endometrial tissue and endometriotic lesions from the same patient and their correlation with the most important angiogenic and fibrinolytic factors. WHAT IS ALREADY KNOWN?: An important role for dysregulated miRNA expression in the pathogenesis of endometriosis is well documented. However, to the best of our knowledge, there are no reports of the relationship between angiogenic and fibrinolytic factors and miRNAs when endometrial tissue and different types of endometriotic lesions from the same patient are compared.

Peritoneal fluid reduces angiogenesis-related microRNA expression in cell cultures of endometrial and endometriotic tissues from women with endometriosis.

Unlabelled: Endometriosis, defined as the presence of endometrium outside the uterus, is one of the most frequent gynecological diseases. It has been suggested that modifications of both endometrial and peritoneal factors could be implicated in this disease. Endometriosis is a multifactorial disease in which angiogenesis and proteolysis are dysregulated.
