Prevalence of HPV Genotypes among Greek Women in Association with Their Potential to Cause Precancerous Lesions. Microorganisms 2024; 12:1404.

Abstract
The escalating global rates of precancerous lesions associated with human papillomavirus (HPV) types not targeted by current vaccines underscore the need to explore the prevalence of HPV types within the Greek female population and their involvement in precancerous lesion development. In the current study, we enrolled a cohort of 253 women aged 18 to 65 years, residing in Greece, who underwent routine screening in three tertiary care referral hospitals. Each participant completed a demographic questionnaire. An HPV DNA test was administered using the VisionArray® HPV kit (ZytoVision GmbH) to qualitatively detect and genotype 41 clinically relevant HPV genotypes. Of all 253 women examined, 114 (45.1%) tested positive for HPV DNA. The primary type detected was HPV51 (high-risk), present in 21 women (8.3% of the total), followed by HPV54 (low-risk) in 17 women (6.7%); HPV16 (high-risk) ranked third, identified in 14 women (5.5%). Among the HPV-positive women, 65 were positive for high-risk HPV types (57% of HPV-positive women) and were referred for colposcopy and cervical biopsy. These procedures identified 24 women with cervical intraepithelial neoplasia 1 (CIN1) lesions and 2 with cervical intraepithelial neoplasia 2 (CIN2) lesions. The most prevalent HPV type among women with CIN1 lesions was HPV16, found in nine (37.5%) women, while HPV51 ranked second, identified in six (25%) women. Both women with CIN2 lesions tested positive for HPV16, whereas one of them was also tested positive for HPV45. Our study is the first to report the prevalence of HPV51 among HPV-positive women in the Greek female population. This highlights the need for further research to fully understand the potential of HPV types not covered by current vaccines, such as HPV51, to cause high-grade lesions or cervical cancer.

Abstract
Infectious diseases are a major concern around the world. Today, it is an urgent need for new chemotherapeutics for infectious diseases. Because of that, our group designed, synthesized, and analyzed 14 new quinoline derivatives endowed with the pharmacophore moiety of fluoroquinolones primarily for their antimicrobial effects. Their cytotoxicity effects were tested against six bacterial and four fungal strains and NIH/3T3 cell line. Additionally, their action mechanisms were evaluated against DNA gyrase and lanosterol 14α-demethylase (LMD). Furthermore, to eliminate the potential side effects, the active compounds were evaluated against the aromatase enzyme. The experimental enzymatic results were evaluated for active compounds' binding modes using molecular docking and molecular dynamics simulation studies. The results were utilized to clarify the structure-activity relationship (SAR). Finally, compound 4m was the most potent compound for its antifungal activity with low cytotoxicity against healthy cells and fewer possible side effects, while compounds 4j and 4l can be used alone for special patients who are suffering from fungal infections in addition to the primer disease.

Abstract
Human papillomavirus (HPV) infection is responsible for approximately 5% of all cancers and is associated with 30% of all pathogen-related cancers. Cervical cancer is the third most common cancer in women worldwide; about 70% of cervical cancer cases are caused by the high-risk HPVs (HR HPVs) of genotypes 16 and 18. HPV infection occurs mainly through sexual contact; however, viral transmission via horizontal and vertical pathways is also possible. After HPV infection of basal keratinocytes or ecto-endocervical transition zone cells, viral DNA persists in the episomal form. In most cases, infected cells are eliminated by the immune system. Occasionally, elimination fails, and HPV infection becomes chronic. Replication of HPVs in dividing epithelial cells is accompanied by increased expression of the E6 and E7 oncoproteins. These oncoproteins are responsible for genomic instability, disruption of the cell cycle, cell proliferation, immortalization, and malignant transformation of HPV-infected cells. Besides, E6 and E7 oncoproteins induce immunosuppression, preventing the detection of HPV-infected and transformed cells by the immune system. HPV integration into the genome of the host cell leads to the upregulation of E6 and E7 expression and contributes to HPV-associated malignization. Prophylactic HPV vaccines can prevent over 80% of HPV-associated anogenital cancers. The vaccine elicits immune response that prevents initial infection with a given HPV type but does not eliminate persistent virus once infection has occurred and does not prevent development of the HPV-associated neoplasias, which necessitates the development of therapeutic vaccines to treat chronic HPV infections and HPV-associated malignancies.

Abstract
Human papillomavirus (HPV), which is linked to specific types of cancer, can be prevented by vaccination. This study aimed to determine the knowledge and attitudes of nursing students about HPV and its vaccine as well as their intentions towards personal vaccination. A total of 536 Spanish nursing students were invited to complete the Spanish version of the questionnaire “Knowledge, attitudes and intentions towards HPV”. Overall, 367 surveys were completed (68.4% response rate). Data analysis included the calculation of three scores: the knowledge score, categorized into low (<33%), moderate (33%–66%), and good knowledge (>66%); the attitude score, sorted into positive (<2.5), neutral (2.5–3.5), and negative attitude (>3.5); and the intention score, categorized into not favorable (<4), neutral (4–7), and favorable intention (>7). Knowledge about HPV and its vaccine was moderate (54.34 ± 0.9%), and the attitude towards vaccination was positive (2.34 ± 0.03). The intention towards personal vaccination increased significantly after completing the questionnaire (before: 4.14 ± 0.27, after: 6.02 ± 0.28; p < 0.001). The present study highlights the need of training future nurses about HPV and its vaccine, considering the important role it plays in the prevention of sexually transmitted diseases.

Abstract
AIM To explore the association between HOTAIR single nucleotide polymorphisms and susceptibility to gastric cancer (GC) in Ningxia, China.
METHODS Three HOTAIR loci rs12826786 (C>T), rs920778 (C>T), and rs4759314 (A>G) were selected for genotyping their polymorphisms; 152 patients with GC and 307 healthy controls were selected after matching age, weight, gender, and other factors. The association between single nucleotide polymorphisms and genetic susceptibility to GC was analyzed by PCR and high-throughput TaqMan technology.
RESULTS The frequency of HOTAIR rs920778 genotype TT was 26.3% and 24.7% in the case group and the control group, respectively; the frequency of genotype C/T was 21.1% and 31.3%; and the frequency of genotype CC was 52.6% and 44.0%. The TT genotype at this locus was significantly associated with genetic susceptibility to GC (P < 0.05). Rs12826786 and rs4759314 were not associated with the risk of GC (P > 0.05). Further stratified analysis found that rs920778 locus was highly associated with genetic susceptibility to GC in men, smoking population, and GC patients with tumor size ≥ 5 cm, but there was no significant association with age, female gender, non-smokers, distant metastasis, or family history of GC.
CONCLUSION HOTAIR rs920778 single nucleotide polymorphism is associated with genetic susceptibility to GC.
