Latinx Youth in Rural Settings: Understanding the Links Between Ethnic-Racial Identity, Neighborhood Risks, Perceived Discrimination, and Depressive Symptoms.

Introduction: The current study examined the relationships between neighborhood risk, perceived ethnic-racial discrimination, and depressive symptoms among rural Latinx adolescents. We also tested for potential moderation effects of ethnic-racial identity (ERI) and how these associations differ by gender.

Methods: Interviewer-administered surveys were used to collect quantitative data for this cross-sectional study in 2017.

Integrating a Community Advisory Board Into a Pragmatic Trial of Mindfulness for Chronic Low Back Pain.

Background: To improve the implementation of clinical trial interventions, there is a need to facilitate communication between key stakeholders and research teams. Community Advisory Boards (CAB) bring together a range of stakeholders not historically included in the research process to inform and work collaboratively with research teams.

Objective: To describe our procedures and processes for (1) integration of a CAB into a pragmatic clinical trial of a telehealth-delivered group mindfulness program for persons with chronic low back pain (cLBP) within primary care, and (2) for the rapid uptake and implementation of CAB recommendations.

A Brief Measure of Fidelity for Mindfulness Programs: Development and Evaluation of the Concise Fidelity for Mindfulness-Based Interventions Tool.

Background: Mindfulness research and clinical programs are widespread, and it is important that mindfulness-based interventions are delivered with fidelity, or as intended, across settings. The MBI:TAC is a comprehensive system for assessing teacher competence, yet it can be complex to implement. A standardized, simple fidelity/engagement tool to address treatment delivery is needed.

Prevalence of SARS-CoV-2 infection in Baja California, Mexico: Findings from a community-based survey in February 2021 in the Mexico-United States border.

Between March 2020 and February 2021, the state of Baja California, Mexico, which borders the United States, registered 46,118 confirmed cases of COVID-19 with a mortality rate of 238.2 deaths per 100,000 residents. Given limited access to testing, the population prevalence of SARS-CoV-2 infection is unknown.

Quantum dot conjugated saporin activates microglia and induces selective substantia nigra degeneration.

Parkinson's disease (PD) is characterized by profound microglial driven inflammatory processes and the loss of dopamine neurons of the substantia nigra (SNc). Both microglia and dopamine neurons that are affected in the SNc are particularly vulnerable to environmental toxicants and finding more selective ways of targeting these cell types is of importance. Quantum dots (QDs) might be a useful vehicle for selectively delivering toxicants to microglia and owing to their fluorescent capability, they can be microscopically tracked within the cell.

Validation of an HPLC Method for Determination of Bisphenol-A Migration from Baby Feeding Bottles.

A simple and economic high-performance liquid chromatography (HPLC-UV-Vis) analytical method was validated for the quantitation of specific Bisphenol-A migration from baby feeding bottles. Overall and specific migration assays were done with different food simulating matrices using the filling method. Good linearity was obtained over the concentration range of 0.

Double-Barrel Extracranial-Intracranial Bypass and Trapping of Dolichoectatic Middle Cerebral Artery Aneurysms: 3-Dimensional Operative Video.

A dolichoectatic intracranial vessel with multiple fusiform aneurysms on the same vessel segment is rare, and usually managed with a bypass with aneurysm trapping. This video demonstrates trapping and a double-barrel superficial temporal artery-to-middle cerebral artery (STA-MCA) bypass to treat two fusiform aneurysms in a left dolichoectatic superior MCA trunk. A 46-year-old man with AIDS presented with aphasia and hemiparesis.

The potential to improve water quality in the middle Rio Grande through effective wetland restoration.

The Rio Grande, which forms the United States-Mexico border for much of its course, receives diverse pollutants from both urban and agricultural areas, most notably in the sister cities of El Paso (TX, USA)-Ciudad Juárez (CHI, Mexico). This study aimed to describe regional trends in water quality in waters near the El Paso-Ciudad Juárez metroplex and to examine the potential for water quality improvement through the use of a created wetland. Very few differences in nutrient chemistry were found among drains, canals and the Rio Grande, with the exception of elevated chloride and lower phosphorus levels found in the drains.

Illicit drug use in seven Latin American countries: critical perspectives of families and familiars.

This cross-sectional multi-centre study explored how family members and friends of illicit drug users perceived protective and risk factors, treatment facilities and policies and laws regarding illicit drug use. Family members and friends of illicit drug users were recruited in 10 urban health care outpatient units in 7 Latin American countries (Brazil, Colombia, Costa Rica, Ecuador, Guatemala, Honduras and Mexico) to complete a questionnaire. The majority of the respondents chose psycho-social factors over genetic or biological explanations as causes of drug problems.
