RESUMO
Background: This literature review explores the role of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and neutrophil-lymphocyte-to-platelet ratio (NLPR) biomarkers, as potential indicators for predicting bacteremia and sepsis in patients with cancer. Objective: Tracing the evolution of interest in this area since 2001, the aim of this review was to report a comprehensive overview of current knowledge and gaps, particularly in patients undergoing immunosuppression. Summary of Findings: The literature research indicates the potential of NLR, PLR, and other biomarkers in diagnosing and predicting sepsis, with some studies emphasizing their value in mortality prediction. A specific focus on bacteremia shows the effectiveness of NLR and PLR as early indicators and prognostic tools, though mostly in noncancer patient populations. While NLR and PLR are promising in general cancer patient populations, the review addresses the challenges in applying these biomarkers to patients with neutropenic and lymphopenic cancer. The NLPR could be considered a significant biomarker for inflammation and mortality risk in various medical conditions, yet its diagnostic accuracy in patients with immunosuppressed cancer is not extensively validated. Conclusion: This review offers a snapshot of the current research on biomarkers in patients with immunocompromised cancer in the sepsis and bacteremia area. More focused research on their application is necessary. This gap underscores an opportunity for future studies to enhance diagnostic and prognostic capabilities in this high-risk group.
RESUMO
Knowledge about HPV and cervical cancer (CC) depends on several factors such as gender and education, which brings implications for health strategies and vaccination. A survey was conducted in Portugal with a representative sample of 1706 university students. Only 55.4% (n=945) had already heard of HPV, although 88.3% (n=834) from that know that is a risk factor for CC. 89% students (n=841) wants to be vaccinated against it, but only 13.8% stated as main reason to be vaccinated "prevention of the disease". Mean scores of knowledge were calculated. Statistical differences were found, regarding "CC knowledge", in gender (p<0.001) and between health sciences schools and non-health sciences schools (p<0.001). Differences regarding the study area in "knowledge and beliefs of HPV" (p<0.001) and in "relation between HPV and CC" (p<0.001) were found. Therefore, these differences may help to develop effective strategies that lead to decline CC incidence and mortality.
