Annexin A2 in Tumors of the Gastrointestinal Tract, Liver, and Pancreas.

Annexin A2 (ANXA2) is a protein that is involved in many physiological and pathological cellular processes. There is compelling evidence that its dysregulated expression, be it up- or downregulation, contributes to the oncogenesis of various neoplasms, including those of the digestive system. The present review summarizes the current knowledge on the role of ANXA2 in the main tumors of the digestive system.

CD26 Is Differentially Expressed throughout the Life Cycle of Infantile Hemangiomas and Characterizes the Proliferative Phase.

Infantile hemangiomas (IHs) are benign vascular neoplasms of childhood (prevalence 5-10%) due to the abnormal proliferation of endothelial cells. IHs are characterized by a peculiar natural life cycle enclosing three phases: proliferative (≤12 months), involuting (≥13 months), and involuted (up to 4-7 years). The mechanisms underlying this neoplastic disease still remain uncovered.

Commissioning of the first hospital-based PET radiopharmaceutical cyclotron in Greece: personnel dose assessment.

The role ofF-fluoro-deoxy-glucose in positron emission tomography (PET) imaging is well established in diagnosis and management of cancer patients. Installations of on-site self-shielded mini cyclotrons are increasing. The Dose on Demand Biomarker Generator BG-75 was installed at Metaxa Cancer Hospital, Greece, in May 2021 and is the first hospital-based PET radiopharmaceutical cyclotron in the country.

Progastrin: An Overview of Its Crucial Role in the Tumorigenesis of Gastrointestinal Cancers.

Defining predictive biomarkers for targeted therapies and optimizing anti-tumor immune response is a main challenge in ongoing investigations. Progastrin has been studied as a potential biomarker for detecting and diagnosing various malignancies, and its secretion has been associated with cell proliferation in the gastrointestinal tract that may promote tumorigenesis. Progastrin is a precursor molecule of gastrin, synthesized as pre-progastrin, converted to progastrin after cleavage, and transformed into amidated gastrin via biosynthetic intermediates.

Second Trimester Amniotic Fluid Angiotensinogen Levels Linked to Increased Fetal Birth Weight and Shorter Gestational Age in Term Pregnancies.

Background: Despite the considerable progress made in recent years in fetal assessment, the etiology of fetal growth disturbances is not as yet well understood. In an effort to enhance our knowledge in this area, we investigated the associations of the amniotic fluid angiotensinogen of the renin-angiotensin system with fetal growth abnormalities.

Methods: We collected amniotic fluid samples from 70 pregnant women who underwent amniocentesis during their early second trimester.

Robotic-assisted fertility sparing surgery in gynecological oncology.

While gynecological malignancies are more commonly diagnosed in elderly women, a substantial proportion of women will still be diagnosed with some type of gynecologic cancer during their reproductive age. Over 10% of newly diagnosed ovarian cancers and over one third of newly diagnosed cervical cancers involve women who are under the age of 45. This, coupled with the rising trend of women having their first child after the age of 35, has led to a concerning prevalence of complex fertility issues among women who have been diagnosed with cancer.

Fallopian tube cytology as a diagnostic tool for adnexal malignancy: the CytoSaLPs score.

Introduction: During the past decade, the theory that high-grade extrauterine pelvic tumors originate from the fallopian tube has been strongly suggested. Our study aims to illuminate the possible role of tubal cytology as an accessory identification tool for gynecologic extrauterine malignancies, allowing in the long term the implementation of population-level cytologic tube evaluation during all benign gynecologic surgeries that do not result in salpingectomy.

Materials And Methods: We ex vivo collect salpingeal epithelial cells from the fibria directly from fresh fallopian tube specimens from women undergoing salpingectomy for any indication.

Diminutive Colon Metastasis From Breast Cancer: An Unexpected Finding in a Patient Undergoing Ulcerative Colitis Surveillance.

Metastatic lesions to the colon are far less common than primary tumors. Breast cancer metastasis to the colon is rarely reported, and it is often atypical in presentation and difficult to diagnose. We present a case of a diminutive asymptomatic breast cancer metastasis to the colon found during surveillance colonoscopy in a patient with long-lasting ulcerative colitis, which was initially regarded as a colitis-associated dysplastic lesion.

Assessment of psychological distress and quality of life of family caregivers caring for patients with chronic diseases at home.

Introduction: Caring for the chronically ill at home is a particularly demanding process that can place a great burden on the caregiver. International and Greek studies underline and confirm this problem. In addition, family caregivers are not supported by the health systems of the different countries, especially in Greece, where the system relies mainly on the family to care for these patients, which is even more challenging during the Covid-19 pandemic.

Experience With J-Plasma Device in Achieving Complete Cytoreduction in Patients With Ovarian Cancer.

Background/aim: Ovarian cancer remains one of the most lethal malignancies in women. Optimal surgical cytoreduction is the most important prognostic factor of survival in patients with advanced ovarian cancer. The helium gas plasma device (J-Plasma) has recently been introduced into surgical treatment of these patients with some promising results.

The Utility of Fallopian Tube Cytology in the Early Detection of Extrauterine Serous Gynecological Malignancies: A Narrative Literature Review.

Introduction: The aim of the study was to analyze the published evidence for the use of fallopian tube brush cytology for the early detection of extrauterine serous gynecological cancer.

Methods: We systematically searched the literature and, additionally, cross-checked on the bibliographies of selected articles. The inclusion criteria involved studies assessing the utility of fallopian tube brush cytology and its applications in the diagnosis, screening, or follow-up of extrauterine serous gynecological cancer.

Immune checkpoint inhibitors and combinations with other agents in cholangiocarcinoma.

Cholangiocarcinoma consists of a heterogeneous group of malignancies with generally poor prognoses. Immunotherapy has emerged in the treatment landscape of many tumors, offering survival benefits, but data regarding the use of immunotherapy for cholangiocarcinoma remain vague. In this review, the authors analyze differences in the tumor microenvironment and various immune escape mechanisms and discuss available immunotherapy combinations with other agents among completed and ongoing clinical trials, such as chemotherapy, targeted agents, antiangiogenic drugs, local ablative therapies, cancer vaccines, adoptive cell therapy and PARP and TGF-β inhibitors.

SUCCOR quality: validation of ESGO quality indicators for surgical treatment of cervical cancer.

Objective: To evaluate whether compliance with European Society of Gynaecological Oncology (ESGO) surgery quality indicators impacts disease-free survival in patients undergoing radical hysterectomy for cervical cancer.

Methods: In this retrospective cohort study, 15 ESGO quality indicators were assessed in the SUCCOR database (patients who underwent radical hysterectomy for International Federation of Gynecology and Obstetrics (FIGO) stage 2009 IB1, FIGO 2018 IB1, and IB2 cervical cancer between January 2013 and December 2014), and the final score ranged between 0 and 16 points. Centers with more than 13 points were classified as high-quality indicator compliance centers.

Fourier Transform Infrared Spectroscopy in the Study of Discrimination of Lobular Breast Cancers.

Background/aim: The early diagnosis of breast cancer plays an important role in reducing mortality and optimizing the prognosis of the disease. The existing visual and histopathological methods do not give any information at a molecular level. Fourier transform infrared spectroscopy does not require any preparation, such as fixation and histological stains.

Space weather phenomena on heart rate: a study in the Greek region.

Many scientific investigations have focused on how space weather phenomena, taking place in the vicinity of the Earth, may influence different aspects of life on Earth and presumably human health itself. From 2005, the National and Kapodistrian University of Athens has established an important position in the field of these investigations by collaborating with various scientists and Institutes, both international and domestic, in different heliobiological projects. In this work, the Cosmic Ray Group of the National and Kapodistrian University of Athens has co-operated with the medical staff from different hospitals and clinics around the country so as to develop large records of medical data (heart rate) which covers a long time period.

A fatal neonatal case of fungemia due to Exophiala dermatitidis-case report and literature review.

Background: Systemic infections caused by the black yeast-like fungus Exophiala dermatitidis are rare, but are associated with high mortality especially in immunocompromised patients. We report the first case of E. dermatitidis fungemia in a premature extremely low birth weight (ELBW) neonate who succumbed despite antifungal therapy with liposomal amphotericin (AMB) and fluconazole.

"Iavazzo score", a preoperative score to predict duration of robotic-assisted gynaecological surgeries.

Background: Long operation time remains a disadvantage of robotic-assisted gynaecological procedures. A score that predicts the duration of such surgeries could be useful.

Methods: A retrospective analysis of robotic-assisted gynaecological surgeries in our institution were conducted.

Fungemia due to Moesziomyces aphidis (Pseudozyma aphidis) in a premature neonate. Challenges in species identification and antifungal susceptibility testing of rare yeasts.

Premature neonates are at particularly increased risk to develop invasive infections with excessive case fatality due to their low birth weight, enteral malabsorbtion, insufficient microbial defenses and underdeveloped anatomic barriers. We present a case of Moesziomyces aphidis (syn. Pseudozyma aphidis) fungemia in a newborn with severe morbidity and prolonged hospital stay.

Trimodality treatment in gastric and gastroesophageal junction cancers: Current approach and future perspectives.

Gastric and gastroesophageal junction (GEJ) cancers represent an aggressive group of malignancies with poor prognosis even when diagnosed in relatively early stage, with an increasing incidence both in Asia and in Western countries. These cancers are characterized by heterogeneity as a result of different pathogenetic mechanisms as shown in recent molecular analyses. Accordingly, the understanding of phenotypic and genotypic correlations/classifications has been improved.
