Retrospective analysis of negative cytology results correlated with a positive high-risk in the human papillomavirus result and subsequent results of patients over a period of three years.

This research paper evaluates the efficacy of co-testing in precluding cervical cancer, with a particular focus on distinguishable outcomes of the human papillomavirus (HPV) vs. cytology tests. A retrospective review of 5948 patients, who tested positive for high-risk HPV but showed negative cytologic findings, revealed that 15.006% tested positive in subsequent screenings. A comparative analysis of various commercial HPV tests highlighted the precision of mRNA-based HPV testing by Aptima (Hologic) in reducing the likelihood of false-negative cytology. The paper challenges the conviction that a negative cytology alone suffices advocating for a condensed testing interval in instances of positive HPV outcomes, thereby facilitating earlier intervention and optimal preventive care. These findings unveil an exigency for reconsidering preventive strategies based on test outcomes.

In Vivo Supportive Effects of Mesenchymal Stem Cells on Fat Graft Stabilization and Local Induction of Angiogenesis Are Not Dependent on the Cell Donor Age or In Vitro Cell Culture Duration.

Mesenchymal stromal cells from adipose tissue (adipose stromal cells, ASCs) are regulators of repair processes in situ by paracrine mechanisms. These unique capabilities make ASCs candidates for the regenerative medicine applications, including cell-assisted lipotransfer method. ASC aging processes have been extensively researched in vitro, there is however limited information about the impact of ASC aging on their biological role in tissue regeneration in vivo. The aim of our study was the research of the possible effects of aging processes of ASCs resulting from the donor age or from in vitro aging during long-term culture (ASC expansion in bioreactors) on their capability to support survival of adipose subcutaneous transplants in rats. The supportive in vivo effects of ASCs from young donors were compared with the effects of ASCs from old donors and ASCs "aged" in long-term in vitro cultures. Fat grafts enriched with ASCs (regardless of their age) retain their volume longer than fat grafts without ASCs supplementation. Vascular expansion in cell-enriched fat grafts was more intense when compared with the controls. It may be concluded that the aging of ASCs does not substantially reduce their ability for the support of the survival of adipose tissue grafts.

Dental status in the Polish senior population and its correlates-Results of the national survey PolSenior.

OBJECTIVE: The aim of the study was to assess dental status of Polish seniors having and wearing dentures in relation to demographic, socioeconomic and lifestyle factors. BACKGROUND: Tooth loss is associated with deterioration of general health status. The epidemiological data on dental status in Poland, including Polish seniors, are fragmented. MATERIALS AND METHODS: The study cohort consisted of 4524 randomly selected participants, aged 65 years and over, representative for Polish seniors. Demographic, socioeconomic, lifestyle factors and dental status were collected using standardised questionnaires. RESULTS: The prevalence of partial and complete edentulism in the Polish senior population was estimated at 45.7% and 47.1%, respectively. Fourteen point four per cent (14.4%) of complete edentulous participants and 31.1% with partial edentulism (1-19 natural teeth) did not have dentures, and one-twelfth of respondents having dentures were not wearing them. The independent correlates of complete edentulism were: female sex, advanced age, rural dwelling, lower education level, physical work in the past, smoking and diabetes. Male sex, age 90+, rural dwelling, type of work, dependence in activities of daily living and partial edentulism were independent correlates of not having dentures and denture disuse. Lower than average personal income was only significant for not having dentures. CONCLUSIONS: Complete edentulism is frequent among older Poles and affects almost 50% of them. It is associated with female sex, age, rural dwelling, poor economic status, smoking and diabetes. Rural dwelling and dependence of daily living are significant correlates of not having dentures and denture disuse.
