The former Tekchem Industrial Unit located in the city of Salamanca, Mexico, constitutes an environmental liability in which the presence of high levels of organochlorine pesticides (OCPs) has been reported. In the present study, levels of OCPs were quantified using gas chromatography-mass spectrometry in 52 soil samples and in 88 blood samples from school-age children in the city of Salamanca. A median concentration of 70.6 ng/g (6.93-3299) was obtained for total OCPs in soil, while for the total sum of dichlorodiphenyltrichloroethane (DDT) the value was 49.6 ng/g (6.93-3276). In children, the median level of the total sum of OCPs was 390 ng/g lipid (7.34-14,895), and for the total sum of DDT was 175 ng/g lipid (< LOD-14,802). The OCPs that resulted in highest concentrations in soil were DDT and its metabolites, as well as aldrin and heptachlor epoxide, while in blood the highest levels corresponded to 4,4'-dichlorodiphenyltrichloroethane (4,4'-DDT) and its metabolites, followed by heptachlor and heptachlor epoxide. The spatial distribution of the concentrations of OCPs in soil shows that the facilities of Tekchem may be a significant potential source for the dispersion of these compounds toward the metropolitan area of Salamanca. The results obtained in the present study demonstrate the presence of OCPs in soil and in child population, providing important bases to study the problem from a broader perspective, while reiterating the importance of continuing efforts to generate resolute and precautionary measures with respect to the environmental liability of Tekchem.

Background: Alzheimer's disease and related dementias (ADRD) disproportionately affect Latinos compared to non-Latino whites. Leveraging the non-monolithic structure of Latin America, which represents a large variability in social determinants of health (SDoH) and high levels of genetic admixture, we aimed to determine contributors to ADRD disparities within Latinos, focusing on genetic ancestry and SDoH.
Method: Community-dwelling participants aged 65 and older (n = 4000) from Cuba, Dominican Republic, Mexico, and Peru completed the 10/66 protocol assessments, including sociodemographic and risk factors questionnaire, neurological exam, cognitive assessment, and blood draw.
Background: Understanding socioeconomic and gender inequalities in physical inactivity during adolescence is a relevant public health issue to promote health in adult life. The aim of this qualitative study is to identify the factors that determine physical activity inequalities in adolescents.
Methods: We selected 2 educational centers in each of the 3 socioeconomic status areas-low, middle, and high-in the city of Madrid.

Background: Daratumumab, an anti-CD38 monoclonal antibody, has been approved for the treatment of multiple myeloma. Data are needed regarding the use of daratumumab for high-risk smoldering multiple myeloma, a precursor disease of active multiple myeloma for which no treatments have been approved.
Methods: In this phase 3 trial, we randomly assigned patients with high-risk smoldering multiple myeloma to receive either subcutaneous daratumumab monotherapy or active monitoring.
Outcomes for Patients with Obesity Undergoing Adrenalectomy for Pheochromocytoma: An International Multicenter Analysis.

Article Synopsis
- This study assesses the outcomes of adrenalectomy for pheochromocytoma in obese versus nonobese patients, using data from 46 centers from 2012 to 2022.
- It finds that while obesity does not significantly increase the rate of complications or comprehensive complication index (CCI), it does lead to a longer hospital stay for patients.
- Furthermore, minimally invasive surgical techniques, like laparoscopic and robotic surgeries, are associated with less morbidity in obese patients, and a retroperitoneal approach may provide additional benefits.
