Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Mutational Pattern in the Fourth Pandemic Phase in Greece.

The aim of this study is to investigate the circulating variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from Athens and from rural areas in Greece during July and August 2021. We also present a rapid review of literature regarding significant SARS-CoV-2 mutations and their impact on public health. A total of 2500 nasopharyngeal swab specimens were collected from suspected COVID-19 cases (definition by WHO 2021b).

Association of -α 308G/A and Gln223Arg Polymorphisms with the Risk of Type 2 Diabetes Mellitus.

Unlabelled: The objective of the present study was to identify the association of the -α- 308G/A and leptin receptor () Gln223Arg polymorphisms with the risk of development of type 2 diabetes mellitus (T2DM).

Methods: A total of 160 volunteers were studied: 108 with T2DM and 52 participants as control, who served as the control group. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for the genomic region of -α- 308G/A and Gln223Arg were carried out.

Computed Tomography-Guided Percutaneous Microwave Ablation for Renal Cell Carcinoma: Impact of Tumor Size on the Progression Survival Rates.

The aim of the present study was to evaluate the safety and efficacy of computed tomography (CT)-guided percutaneous microwave ablation (MWA) of renal cell carcinoma (RCC) along with identifying prognostic factors affecting the progression survival rate. Institutional database retrospective research identified 69 patients with a biopsy proven solitary T1a (82.6%) or TIb (17.

Pelvic Exenteration Put into Therapeutical and Palliative Perspective: It Is Worth to Try.

Pelvic exenteration (PE) is one of the most drastic operations in surgical oncology, associated with severe morbidity and mortality. The objective of our study was to review our experience of PE in terms of surgical characteristics, complications, and overall survival. All patients who had PE surgery between January 1999 and December 2015 were identified.

Fertility Risk Assessment and Preservation in Male and Female Prepubertal and Adolescent Cancer Patients.

Cancer represents the second cause of death in prepubertal children and adolescents, although it is currently associated with an overall survival rate of 80%-85%. The annual incidence rate is 186.6 per 1 million children and adolescents aged up to 19 years.

Evaluation of acute toxicity and symptoms palliation in a hypofractionated weekly schedule of external radiotherapy for elderly patients with muscular invasive bladder cancer.

Aim: To evaluate acute toxicity and symptoms palliation of a weekly hypofractionated 3DCRT schedule as radical treatment in elderly patients with organ confined bladder cancer cT1-2N0.

Materials And Methods: Between February 2005 and June 2011, 58 prospectively selected patients diagnosed with organ confined bladder cancer were treated with external 3DCRT (4-field arrangement). All candidates were medically inoperable, with poor performance status, and with age ranged from 75 to 88 years (median 78).

Tissue inhibitor of metalloproteinase-2 as a multifunctional molecule of which the expression is associated with adverse prognosis of patients with urothelial bladder carcinomas.

Purpose: Tissue inhibitors of metalloproteinases (TIMPs) regulate matrix metalloproteinase (MMP) activity controlling the breakdown of extracellular matrix components and, thus, play an important role in the process of invasion and metastasis. Moreover, there are several new functions, growth control, apoptosis, and angiogenesis-, in which TIMPs seem to be involved. The aim of this study was to elucidate the role of TIMP-2 in human urothelial cancer assessing TIMP-2 protein expression in 106 urothelial bladder carcinomas and evaluating its importance relative to clinicopathologic parameters (age, gender, histological grade, and stage) and patient survival, as well as to markers associated with cell growth and apoptosis (Ki-67, p53, and bcl-2).
