Sexually transmitted diseases (STDs) affect mainly young individuals and cause health, social, and economic problems worldwide. The present study used a web questionnaire to assess the awareness, knowledge, sexual behaviors, and common practices regarding STDs in young Greek adults. The 1833 individuals, aged 18–30 years, who responded to the study seem to be particularly knowledgeable regarding STDs such as AIDS (97.7%), warts (97%), Chlamydia (92.2%), genital herpes (89.9%), syphilis (81.9%), and gonorrhea (72.1%), whereas lower percentages were noted for trichomoniasis (39.3%), Molluscum contagiosum (12.9%), mycoplasmosis (11.6%), and amoebiasis (7.4%). Regarding oral STD transmission, participants replied correctly for genital herpes (45%), warts (35.8%), and AIDS (HIV; 33.8%), whereas 30.2% were unfamiliar with oral sexual transmission. Of the participants, 52% were not aware that STDs might cause infertility. Only 40.4% of the respondents reported always using condoms during sexual intercourse, and 48.6% had never been tested for STDs. The majority of the young population (55%) presented a moderate knowledge STD score (41–60%) and was associated with demographic parameters such as age, gender, sexual preference, number of sexual partners, and residence (p < 0.05). These findings provide important information regarding the prevention of STDs and highlight the significance of developing more effective sex education programs for young people in Greece.

Recent trends have shown a dramatic rise in the incidence of oropharyngeal squamous cell carcinoma strongly associated with high-risk human papillomavirus (HPV) of type 16. The genetic variability of HPV16 has been extensively studied in cervical cancer but there are very limited published data concerning the genetic variations of this HPV type in oropharyngeal cancer. In the present study, the genetic variations of HPV16 E6 gene sequences originated from a small cohort of Greek patients diagnosed with oropharyngeal cancer were assessed. The vast majority of the sequences clustered within the European variant branch. The T350G variation was found to be the predominant one. This finding may indicate the need for further studies that could explain the possible impact of this variant in the pathomechanisms of oropharyngeal cancer.

Prostate cancer (PCa) is the most common genitourinary malignancy in men, with a multifactorial etiology influenced by genetic, environmental, and microbial determinants. Although the prostate was traditionally considered sterile, advances in microbiome research have challenged this view, revealing potential links between microbial communities and PCa development, progression, and treatment response. This review synthesizes evidence on the gut, urinary, seminal fluid, and prostatic microbiomes, highlighting their potential contributions to PCa pathogenesis and therapeutic outcomes. Key studies utilizing next-generation sequencing (NGS), whole-genome sequencing (WGS), PCR, and metagenomic analyses have identified specific bacterial and fungal taxa associated with Pca; however, findings remain inconsistent across methodologies and cohorts. Microorganisms such as Propionibacterium acnes and Pseudomonas spp. may modulate inflammation, immune responses, and resistance to androgen-deprivation therapy. Further research is required to determine whether microbial signatures can serve as reliable biomarkers for early detection, prognosis, or novel therapeutic strategies in PCa management.

Examining the psychopathology of patients who have contracted coronavirus disease 2019 remains important. The current study aims to investigate the relationship between depression, cognitive and executive functions, and their impact on quality of life. First, a comprehensive bibliographic review of relevant scientific articles and studies was carried out. Data were then collected using weighted and appropriate questionnaires. Analysis of variance and multiple regression analyses were conducted to examine the relationship between the independent variables (depression, cognitive and executive functions, and demographic factors) and the dependent variable (quality of life), to interpret and analyze the resulting associations. In contrast to depression, cognitive and executive functions did not appear to significantly influence patients’ quality of life and well-being. Further scientific research is necessary to explore these factors and their potential effects more thoroughly.

Background: The Bcl-2 protein is a member of the bcl family of proteins, which play a key role in the cell apoptosis process. Its tumorigenic potential has been established long ago in animal experimental models, and was subse¬quently supported by the finding of its overexpression in a variety of human tumours. Bcl-2 has been suggested as a prognostic marker for the neoplastic diseases; new evidence keeps arising providing further support to this finding. Aim: This study investigated the association of Bcl-2 expression with prognostically important clinicopathological fea¬tures in breast carcinoma in the Greek population. Methodology: Immunohistochemical assessment of Bcl-2 was conducted in a case series of 100 surgically resected primary breast carcinomas from November 2022 to July 2023 and the association of Bcl-2 with the grade of histological differentiation and Lymph nodes pN was statistically inves¬tigated. Results: The histological grade profile of the studied samples was: Grade III (24%), Grade II (62%), Grade I (14%). High (score 3+) Bcl-2 expression was found in 65% of cases, moderate (score 2+) expression in 12%, low (score 1+) in 4%, while negative expression was shown in 19% of the samples. A statistically significant inverse association between Bcl-2 expression and the grade of histological differentiation was detected (Phi=-0.850, p=< 0.0001). Bcl-2 expression was also inversely associated with Lymph nodes pN stage (p=0.001). Conclusion: The observed association of immunohistochemical Bcl-2 expression with clinicopathological characteristics which are known prognositc indicators for breast cancer (grade and pN stage) provides confirmatory evidence to the potential important prognostic value of this marker in breast cancer. Future investigations should incorporate Bcl-2 expression in multivariate prediction models to weigh its value in the clinical management of breast cancer.

Background: Breast carcinoma is among the three most common types of cancer worldwide, including lung cancer and colon cancer, regardless of gender. The Bcl-2 oncogene is involved in a number of malignant neoplasms, includ¬ing leukaemia and lymphoma, through the regulation of the cell apoptosis process. Aim: The main purpose of the present study is to investigate the association of Bcl-2 with other molecular parameters of significant prognostic and predictive value for disease and more specifically the ER and PR receptors, along with HER-2 and Ki-67 (MIB-1). Methodology: Immunohistochemical assessment of Bcl-2, ER and PR receptors, HER-2 and Ki-67 was conducted in a case series of 100 surgically resected primary breast carcinomas and the association of Bcl-2 with the other bi¬omarkers was statistically investigated. Results: High (3+) Bcl-2 expression was observed in 65% of cases, moderate (2+) in 12%, low (1+) in 4% and negative expression in 19%. Association of Bcl-2 with ER-PR receptors and HER2 and Ki67 was conducted with Fisher’s exact and Chi square (x2) test of Cramer's V statistics tests were performed where appropriate. Bcl-2 oncogene was positively and highly associated with estrogen ER receptors (Phi=0.760, p=<0.0001); the findings of the association of Bcl-2 oncogene with PR progesterone receptors were similar: a positive association was found between the two specific biomarkers (Phi=0.626, p=<0.0001). Finally, negative association of Bcl-2 with HER2 (Phi=-0.350, p=<0.0001). Conclusion: Considering the association of Bcl-2 expression with the ex¬pression of genes that are related to therapy prediction (ER and PR) it remains to be ascertained whether Bcl-2 could be used as a potential predictive marker. Moreover, the negative association of Bcl-2 with Ki67 and HER2 should be furthermore investigated for its association with disease outcome and response to targeted therapy. Overall, this study suggests that Bcl-2 should be further tested for its incorporation into a multivariate prediction model for breast cancer therapy. In addition, more investigations are required into targeted anti-Bcl-2 therapy may be used to modify re¬sponses to current breast cancer therapy, in order to reduce resistance.
