Abstract
Cancer is considered the most important clinical, social and economic issue regarding cause‑specific disability‑adjusted life years among all human pathologies. Exogenous, endogenous and individual factors, including genetic predisposition, participate in cancer triggering. Telomeres are specific DNA structures positioned at the end of chromosomes and consist of repetitive nucleotide sequences, which, together with shelterin proteins, facilitate the maintenance of chromosome stability, while protecting them from genomic erosion. Even though the connection between telomere status and carcinogenesis has been identified, the absence of a universal or even a cancer‑specific trend renders consent even more complex. It is indicative that both short and long telomere lengths have been associated with a high risk of cancer incidence. When evaluating risk associations between cancer and telomere length, a disparity appears to emerge. Even though shorter telomeres have been adopted as a marker of poorer health status and an older biological age, longer telomeres due to increased cell growth potential are associated with the acquirement of cancer‑initiating somatic mutations. Therefore, the present review aimed to comprehensively present the multifaceted pattern of telomere length and cancer incidence association.

Abstract
e15611 Background: The incidence of Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE) after colorectal surgery is approximately 29% and 1.6% respectively. The incidence of asymptomatic postoperative DVT in colorectal cancer (CRC) patients has been reported as high as 20%, even under thromboprophylaxis. Thus, thromboprophylaxis after surgical treatment for CRC is crucial. Latest guidelines from International Initiative on Thrombosis and Cancer (ITAC 2019) recommend use of highest prophylactic dose of Low Molecular Weight Heparin (LMWH). Methods: Onco-CAST is a prospective, phase IV, observational, non-interventional cohort study evaluating a) current management approach for CRC surgical prophylaxis and b) efficacy and safety of tinzaparin at 8.000 Anti-Xa IU, once daily (OD), for at least one month post hospital discharge. Patients enrolled after signing informed consent. Onco-CAST was conducted by the Hellenic Society of Coloproctology. Results: Results from 175 CRC patients from 9 Onco Surgical Clinics are reported. Participation completed 79% of patients at report time: 66% males, 67±12 years, BMI: 27.4±5.5. Histology: adenocarcinomas NOS 81%, mucinous adenocarcinomas 9%, small cell neuroendocrine carcinomas 2%, and others. High grade differentiation indicated: 26% and 5% metastatic. 32% treated with right hemicolectomy, 20% with low anterior resection, 12% with sigmoid colectomy, 9% with abdominal-perineal resection, 9% with left hemicolectomy and other methods. 67% treated open and 33% laparoscopic while the median number of lymph nodes dissected for left and right hemicolectomy was 32.5 (Q1-Q3:26-38) and 24 (Q1-Q3: 14.5-32), p = 0.0253. Factors related to thrombosis risk are presented in table, notably, 95% of patients accumulated ≥3 risk factors. Median thromboprophylaxis duration with tinzaparin 8.000 Anti-Xa IU, OD, was: 37 days (1st-3rd quartile: 33-45 days). Three thrombotic events occurred (efficacy 98.3%, 95% CI: 95.1-99.4%), one DVT+PE, one DVT and one due to Central Venous Catheter (CVC). Eight patients experienced bleeding events (4.6%, 95%CI: 2.3-8.8%), 3 minor, 3 major and 2 CNMB, 2 had a possible relation to thromboprophylaxis (1.1%, 95%CI: 0.3-4.1%). Conclusions: Thromboprophylaxis in Surgically Treated Colorectal Cancer Patients with Tinzaparin intermediate dose seems safe and efficient approach.[Table: see text]

Abstract
Soon after the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in December, 2019, numerous research teams, assisted by vast capital investments, achieved vaccine development in a fraction of time. However, almost 8 months following the initiation of the European vaccination programme, the need for prospective monitoring of the vaccine-induced immune response, its determinants and related side-effects remains a priority. The present study aimed to quantify the immune response following full vaccination with the BNT162b2 coronavirus disease 2019 (COVID-19) mRNA vaccine by measuring the levels of immunoglobulin G (IgG) titers in healthcare professionals. Moreover, common side-effects and factors associated with IgG titers were identified. For this purpose, blood samples from 517 individuals were obtained and analysed. Blood sampling was performed at a mean period of 69.0±23.5 days following the second dose of the vaccine. SARS-CoV-2 IgG titers had an overall mean value of 4.23±2.76. Females had higher titers than males (4.44±2.70 and 3.89 ±2.84, respectively; P=0.007), while non-smokers had higher titers than smokers (4.48±2.79 and 3.80±2.64, respectively; P=0.003). An older age was also associated with lower antibody titers (P<0.001). Moreover, the six most prevalent adverse effects were pain at the injection site (72.1%), generalized fatigue (40.5%), malaise (36.3%), myalgia (31,0%), headache (25.8%) and dizziness/weakness (21.6%). The present study demonstrated that the immune response after receiving the BNT162b2 COVID-19 mRNA vaccine is dependent on various modifiable and non-modifiable factors. Overall, the findings of the present study highlight two key aspects of the vaccination programs: First, the need for prospective immunosurveillance studies in order to estimate the duration of immunity, and second, the need to identify those individuals who are at a greater risk of developing low IgG titers in order to evaluate the need for a third dose of the vaccine.

Abstract
John Allen, a British physician of the eighteenth century, deserves being remembered for a series of inventions, but most importantly -- from a 'medical' point of view -- for his highly praised manuscript, the 'Universae Medicinae Practicae,sive Doctissimorum Virorum de Morbis Eorumque Causis ac Remediis Judicia', which long served as a text-book for medical students of the time, and also as a reference book for practitioners throughout European countries, for several decades after its original first publication. It contains the opinions ('Sententiae') of the most celebrated authors of all ages, from Hippocrates, Galen and Avicenna up to Allen's contemporaries, concerning a wide number of diseases, their causes, signs, symptoms, and therapeutical remedies where available. The present paper deals mostly with parts of the Synopsis concerning renal diseases and related clinical signs.
