Purpose: The aim of this study was to compare the diagnostic performance of the Gynecology Imaging Reporting and Data System (GI-RADS) and Ovarian-Adnexal Reporting and Data System (O-RADS) ultrasound (US) classification systems and assess their capacity to stratify the risk of malignancy in adnexal masses (AMs).

Methods: A comprehensive search of MEDLINE (PubMed), Scopus, Web of Science, and Google Scholar was conducted to identify articles published between January 2020 and August 2023. The quality of the studies, the risk of bias, and concerns regarding applicability were assessed using QUADAS-2.

Article Synopsis
  • Epidemiological studies indicate that exposure to green spaces during childhood could potentially lower the risk of developing ADHD symptoms.
  • The research focused on both prenatal and early childhood exposure to greenness, examining its effects on ADHD symptoms in children up to age 12, while also considering the roles of pollution and physical activity.
  • Results showed significant negative associations between early childhood greenness and ADHD symptoms, particularly at close distances to residences, suggesting a protective effect, but no mediation through pollution or physical activity was identified.

The placenta plays a crucial role in protecting the fetus from environmental harm and supports the development of its brain. In fact, compromised placental function could predispose an individual to neurodevelopmental disorders. Placental epigenetic modifications, including DNA methylation, could be considered a proxy of placental function and thus plausible mediators of the association between intrauterine environmental exposures and genetics, and childhood and adult mental health.

In the last decade, we have witnessed important advances in novel therapeutics in the management of gynecologic cancers. These studies have built on the findings from preexisting data and have provided incremental contributions leading to changes that have not only impacted the accuracy of cancer detection and its metastatic components but also led to improvements in oncologic outcomes and quality of life. Key landmark trials have changed the standard of care in cervix, uterine, and ovarian cancer.

Article Synopsis
  • Telomere length (TL) and mitochondrial DNA copy number (mtDNAcn) are crucial biomarkers for assessing aging and oxidative stress; researchers hypothesized that exposure to methylmercury (MeHg) from fish would shorten TL and reduce mtDNAcn due to increased oxidative stress.
  • A study involving children aged 6-11 from six European countries measured prenatal and postnatal mercury levels and determined TL and mtDNAcn, while controlling for factors like lifestyle and fish consumption.
  • Results indicated that higher blood mercury levels were associated with longer TL, particularly during prenatal exposure, with significant variation based on concentration, while no changes in mtDNAcn were observed; further research is needed to understand these effects and their health implications.

Article Synopsis
  • Mercury is widely used in industry and products, leading to significant environmental contamination and occupational exposure, with genetic factors potentially influencing how it is absorbed and metabolized in the body.
  • A study analyzed blood mercury levels in pregnant women and children to identify genetic variations (SNPs) linked to mercury concentrations, finding an estimated heritability of 24% in pregnant women but not in children.
  • The research identified 16 SNPs connected to mercury levels in pregnant women and 21 in children, but there was no significant overlap or conclusive results, suggesting differences in metabolism and the need for further validation of these findings.

Human exposure to mycotoxins is a global concern since filamentous fungi can contaminate food and feed from crops to ready-to-eat meals. Human urine biomonitoring is a widely used technique to evaluate mycotoxins exposure, as an alternative to food correlation studies. The aim of this study is to describe human exposure to mycotoxins and to investigate the associated sociodemographic, lifestyle and dietary variables.

Scope: The aim of the study is to investigate in Jurkat cells the possible beneficial effect of pumpkin (P) and fermented milk whey (FW) mixture against aflatoxin B1 (AFB1) and ochratoxin A (OTA) induced alterations in gene expression profile.

Methods And Results: Human T cells are exposed for 7 days to digested bread extracts containing P-FW mixture along with AFB1 and OTA, individually and in combination. The results of RNA sequencing show that AFB1 P-FW exposure resulted in 34 differentially expressed genes (DEGs) while 3450 DEGs are found in OTA P-FW exposure and 3264 DEGs in AFB1-OTA P-FW treatment.

Background: Inorganic arsenic (iAs) is a widespread toxic metalloid. It is well-known that iAs metabolism and its toxicity are mediated by polymorphisms in AS3MT and other genes. However, studies during pregnancy are scarce.

The toxic effects of mercury exposure on human health are a public health concern. The most important source of this exposure is the consumption of fish and marine mammals. This study aims to describe hair mercury concentrations and their evolution from birth until eleven years of age in adolescents from the INMA (Environment and Childhood) birth cohort study, and to assess the association of hair mercury concentrations at eleven years of age with sociodemographic and dietary factors.

Sedentary behaviour (SB) may be related to telomere length (TL) attrition due to a possible pro-inflammatory effect. This study examined the association between parent-reported sedentary behaviour (SB) and leukocyte TL at the age of 4 and telomere tracking from 4 to 8 years. In the Spanish birth cohort Infancia y Medio Ambiente (INMA) project, we analysed data from children who attended follow-up visits at age 4 (n = 669) and 8 (n = 530).

Background: Uterine adenomyosis is an increasingly frequent disorder. Our study aimed to demonstrate the presence of obstetric complications in the population affected by this condition to demonstrate the need for follow-up in high-risk obstetric units.

Material And Methods: The data for the study were obtained from TriNetX, LLC, between 2010 and 2020.

Article Synopsis
  • Recent research indicates that the placenta plays a significant role in neurodevelopment and may contribute to the onset of neuropsychiatric disorders later in life.
  • A new placental methylation quantitative trait loci (mQTL) database was created, incorporating data from 368 fetal placenta samples to explore the genetic ties between placental DNA methylation and neuropsychiatric disorders using advanced statistical methods.
  • Findings suggest that certain genetic risks for schizophrenia, bipolar disorder, and major depressive disorder may be linked to DNA methylation activity in the placenta, influencing gene expression associated with these disorders.

Aflatoxin B1 (AFB1) and ochratoxin A (OTA) are typical contaminants of food and feed, which have serious implications for human and animal health, even at low concentrations. Therefore, a transcriptomic study was carried out to analyze gene expression changes triggered by low doses of AFB1 and OTA (100 nM; 7 days), individually and combined, in human lymphoblastic T cells. RNA-sequencing analysis showed that AFB1-exposure resulted in 99 differential gene expressions (DEGs), while 77 DEGs were obtained in OTA-exposure and 3236 DEGs in the combined one.

Higher maternal pre-pregnancy body mass index (ppBMI) is associated with increased neonatal morbidity, as well as with pregnancy complications and metabolic outcomes in offspring later in life. The placenta is a key organ in fetal development and has been proposed to act as a mediator between the mother and different health outcomes in children. The overall aim of the present work is to investigate the association of ppBMI with epigenome-wide placental DNA methylation (DNAm) in 10 studies from the PACE consortium, amounting to 2631 mother-child pairs.

Article Synopsis
  • - Mycotoxin contamination in food is a global health issue, so it's important to monitor human exposure, primarily through urine where these toxins are found.
  • - This study aimed to develop and validate a sensitive method using Liquid Chromatography coupled to Quadrupole Time of Flight Mass Spectrometry (LC-Q-TOF-MS) to detect ten specific mycotoxins while also identifying others.
  • - The researchers employed various extraction methods and settled on a modified QuEChERS technique, achieving good recovery rates for the mycotoxins, and tested the final method on urine samples from women, finding higher levels of specific untargeted mycotoxins.
