Article Detection of Toxoplasma Gondii and High-Risk Human Papillomaviruses in FFPE Malignant and Benign Breast Lesions Using Real-Time Pcr(Dove Medical Press Ltd, 2025) Usluca, Selma; Bakir, Ayfer; Arikok, Ata Turker; Korkut, Gizem; Yagiz, Gulsah Ceylan; Alper, MuratObjective: Breast cancer is the most prevalent malignancy among women. In recent years, it has been suggested that various pathogens such as Toxoplasma gondii (T. gondii) and human papillomavirus (HPV) may play a potential role in the development of breast cancer. This study aimed to determine the prevalence of T. gondii and HPV infections in formalin-fixed paraffin-embedded tissue samples of breast cancer patients using real-time PCR. Methods: The study included 136 paraffin-embedded biopsy samples with w confirmed malignant breast tumor diagnosis and 50 breast tissue samples diagnosed as benign breast lesions, serving as controls. The presence of T. gondii DNA and high-, medium-, and low-risk HPV genotype DNAs were investigated using the real-time PCR method. First, deparaffinization was performed using xylene and alcohol, followed by DNA extraction and real-time PCR amplification. Results: The most common histopathological types of malignant breast carcinoma were invasive carcinoma (n=82; 60.3%), invasive lobular carcinoma (n=26; 19.1%), invasive ductal carcinoma (n=8; 5.9%), and mixed invasive carcinoma (n=8; 5.9%). According to the Modified Bloom-Richardson classification, 55.15% of malignant breast tumor samples were grade 2, 32.4% were grade 3, and 12.5% were grade 1. Real-time PCR analysis did not detect T. gondii DNA or HPV DNA in any of these samples. Conclusion: Our findings do not support a role of T. gondii and HPV in breast cancer development. To better understand the possible relationship between breast cancer and these pathogens, further studies with larger sample sizes, diverse diagnostic methods, and broder geographical coverage are necessary.Article Citation - WoS: 7Citation - Scopus: 9Predictors of Parenting Stress in Parents of Children With Cancer(Elsevier Sci Ltd, 2021) cinar, Sevil; Boztepe, Handan; Ay, Ayse; Yilmaz, Pinar; Gullu, Hafize; Karadavut, Burcu; Akyuz, CananPurpose: In the present study, we investigated the parenting stress experienced by parents of children with cancer and the influencing factors. Method: This was a cross-sectional and descriptive correlational study that consisted of parents of 136 children in the age group of 0-18 years who were followed up for cancer in the outpatient clinics and services of a university hospital in Turkey. Parenting Stress Index, Burden Interview, Multidimensional Scale of Perceived Social Support, Marital Life Satisfaction Scale, and Ways of Coping Questionnaire were used to collect the data. Results: No statistically significant difference was found between the parenting stress mean scores and gender of the parents of children with cancer (t = -0.350; P = 0.727). The results of the present study showed that the economic status (t = -4.16; P = 0.000), parents' physical (t = 3.606; P = 0.000) and mental health status after the child is diagnosed (t = 5.647; P = 0.000), accompanying mental health problems of the child (t = 2.567; P = 0.011), and diagnosis of children at a young age (t = -2.776; P = 0.006) increased the parenting stress of the parents. Conclusions: Nursing interventions can reduce parental stress by providing sufficient care and support during the disease process.
