Article Synopsis
- A team of over 180 researchers from more than 40 countries is addressing the issues related to "phantom agents," which are proposed pathogenic agents that are listed without concrete evidence of their existence.
- These phantom agents, identified only through symptoms and lacking proper isolates or genetic data, create obstacles for trade and plant certification, making effective detection and risk assessment difficult.
- The researchers recommend removing these agents from regulatory lists and updating standards in line with modern diagnostic methods to facilitate germplasm exchange and support global agriculture.
Neutrophil/lymphocyte and platelet/lymphocyte ratio in seropositive women for human immunodeficiency virus (HIV) and human papillomavirus (HPV) coinfection.
Rev Inst Med Trop Sao Paulo
December 2024
This study aims to investigate the possible association between neutrophil/lymphocyte and platelet/lymphocyte ratio in women with HIV, undergoing antiretroviral treatment, with HPV coinfection. This is a cross-sectional study with HIV positive women; their biological samples were collected for laboratory tests (complete blood count) and oncotic cytology for detection of HPV DNA, by PCR-Nested (PGMY and GP primers). Viral load and CD4 and CD8 T-cells counts were obtained from medical records.

Design: Qualitative descriptive study. The Integrated Health Networks Model was the theoretical framework of reference.
The objective was to analyze the longitudinal associations of physical activity (PA) and Sedentary behavior (SB) on bone health indicators (BHI) in healthy young adults. Articles were selected from five databases and 17 longitudinal studies were selected after meeting the inclusion and exclusion criteria. Among these, only one study assessed the association between childhood PA and adult BHI, the results showed no significant association between PA and BHI.

- - The MCM8 gene is crucial for repairing DNA breaks and maintaining cell health, and its dysfunction can lead to cell death, especially in relation to primary ovarian insufficiency.
- - The study aimed to evaluate a specific variant of the MCM8 gene (NG_042869.1:g.40270G>A) in women with primary ovarian insufficiency by comparing samples from affected individuals to those from a control group.
- - Results showed the variant was present in one sample from the case group but absent in the control group, indicating it may be a rare, pathogenic variant associated with primary ovarian insufficiency in the studied population.
