Why Is Surgery Still Done after Concurrent Chemoradiotherapy in Locally Advanced Cervical Cancer in Romania?

The incidence and mortality of cervical cancer are high in Romania compared to other European countries, particularly for locally advanced cervical cancer cases, which are predominant at the time of diagnosis. Widely accepted therapeutic guidelines indicate that the treatment for locally advanced cervical cancer consists of concurrent chemoradiotherapy (total dose 85-90 Gy at point A), with surgery not being necessary as it does not lead to improved survival and results in significant additional morbidity. In Romania, the treatment for locally advanced cervical cancer differs, involving lower-dose chemoradiotherapy (total dose 60-65 Gy at point A), followed by surgery, which, under these circumstances, ensures better local control.

A Catastrophic Biodiversity Loss in the Environment Is Being Replicated on the Skin Microbiome: Is This a Major Contributor to the Chronic Disease Epidemic?

There has been a catastrophic loss of biodiversity in ecosystems across the world. A similar crisis has been observed in the human gut microbiome, which has been linked to "all human diseases affecting westernized countries".

Gut Microbiome, Functional Food, Atherosclerosis, and Vascular Calcifications-Is There a Missing Link?

The gut microbiome is represented by the genome of all microorganisms (symbiotic, potential pathogens, or pathogens) residing in the intestine. These ecological communities are involved in almost all metabolic diseases and cardiovascular diseases are not excluded. Atherosclerosis, with a continuously increasing incidence in recent years, is the leading cause of coronary heart disease and stroke by plaque rupture and intraplaque hemorrhage.

A Better Understanding of Axillary Lymph Node Dissection in the Era of Sentinel Lymph Node Biopsy.

Axillary lymph node dissection (ALND) was and still is an important part of breast cancer treatment despite the fact the sentinel lymph node biopsy (SLNB) has revolutionized breast cancer surgery. SLNB provides the same prognostic information as ALND but with significantly less morbidity. The results of numerous trials conducted over the past 20 years have crowned SLNB as the gold standard for early breast cancer treatment.

Pregnancy-Related Extracellular Vesicles Revisited.

Extracellular vesicles (EVs) are small vesicles ranging from 20-200 nm to 10 μm in diameter that are discharged and taken in by many different types of cells. Depending on the nature and quantity of their content-which generally includes proteins, lipids as well as microRNAs (miRNAs), messenger-RNA (mRNA), and DNA-these particles can bring about functional modifications in the receiving cells. During pregnancy, placenta and/or fetal-derived EVs have recently been isolated, eliciting interest in discovering their clinical significance.

Breast cancer mortality gaps in Romanian women compared to the EU after 10 years of accession: Is breast cancer screening a priority for action in Romania? (Review of the Statistics).

Breast cancer remains the most common cause of morbidity and mortality by cancer in females worldwide, even though it is largely preventable through population screening. Despite notable progress in the last years in the EU, breast cancer screening programs still maintain wide variations among countries and socio-economic groups. This statistical review aimed to investigate the breast cancer-related health gaps in Romanian women compared to the average EU female population after 10 years of accession (2007-2016).

Analysis of TP53 gene and particular infrastructural alterations in invasive ductal mammary carcinoma.

This study was conducted in order to determine the mutational status of TP53 gene and to determine some particular aspects from ultrastructural level in invasive mammary ductal carcinoma. The cellular signaling pathway involving the TP53 gene acts in biological deoxyribonucleic acid (DNA) repair processes and cell cycle arrest following a signal transmitted to the p53 protein when posttranslational changes occur in the cell due to stress induced in the cell by both intrinsic and extrinsic factors. Cellular stress activates the transcription factor function of the protein that initiates, as the case may be, either DNA repair or programmed cell death (apoptosis).

Pathological Examination of the Late Embryonic Heart Using the Same 4-chamber and 3-vessel Planes Used in Fetal Echocardiography.

Background/aim: The incidence of early pregnancy loss widely varies according to age, being considerably higher in older women. Severe congenital malformations play an important role in pregnancy loss, having a high risk of recurrence. Congenital heart defects are the most common congenital abnormalities, thus the diagnosis of such malformations in aborted embryos is important for establishing both a possible cause for pregnancy loss and for correctly counseling the parents.

Impact of histological subtype on the response to chemoradiation in locally advanced cervical cancer and the possible role of surgery.
