Objective A well-established association exists between academic performance and levels of depression and anxiety among medical students. However, the effects of positive psychological factors on symptoms of depression and anxiety and academic performance have not been adequately studied. This study explores the relationship between the above variables and identifies positive psychological factors that can promote medical student wellbeing.

- Traditional single-point measurements are ineffective for capturing the complex, dynamic chemical responses of plants in their root environments.
- TETRIS is a real-time chemical phenotyping system that uses low-cost electrochemical sensors to continuously monitor key factors like salt concentration, pH, and hydroxyl ions in plant roots.
- TETRIS has shown the ability to differentiate nutrient uptake in various plants (like tomato, kale, and rice) and can potentially enhance high-throughput screening for developing high-yield, stress-resistant plant varieties.
Objectives: The association between the coronavirus disease (COVID-19) pandemic and adverse mental health outcomes has been well documented; however, little is known about its impact in rural areas of the United States. This study aims to characterize and compare inpatient psychiatric admissions in West Texas before and during the initial months of the COVID-19 pandemic.
Methods: A retrospective study was conducted using the electronic health records of 1392 inpatient psychiatric admissions from period A (March 13, 2019-July 3, 2019) to period B (March 13, 2020-July 3, 2020).
The study evaluated non-financial incentive packages to retain health extension workers in the Somali Region of Ethiopia using the Discrete Choice Experiment (DCE) technique, conducted among 66 health extension workers in 3 (districts). The study used a mix of qualitative and quantitative methods in sequential order. Mixed logic regression modeling was used to determine the effect of different job attributes on the retention of the health extension workers, while Preference Impact Measure (PIM) was used to determine the combinations of preferred incentive packages to retain the health extension workers in their current workplace.

- * Researchers developed a machine learning model that uses point-of-use measurements of ammonia (NH), soil conductivity, pH, and weather data to predict soil nitrate (NO) levels with a correlation of R = 0.70.
- * The long short-term memory (LSTM) neural network can forecast NH and NO levels up to 12 days ahead from a single measurement, providing a tool for better fertilization planning that can reduce overfertilization and enhance crop yields.
Article Synopsis
- The study investigates the complex dynamics between sex workers and clients in the context of the fentanyl overdose crisis in Vancouver, focusing on how drug use shapes these interactions.
- Based on ethnographic research, including interviews with 34 street-based sex workers, findings highlight that sex workers often provide harm reduction services to clients to mitigate overdose risks, which also increases their hidden labor.
- The research emphasizes the negative impact of criminalization and stigma around drug use and sex work, suggesting a need for sex worker-led overdose prevention strategies to enhance safety and health for both sex workers and clients.
ABSTRACT Diverse isolates of the soilborne wilt fungi Verticillium dahliae and V. albo-atrum were studied to understand the nature and origins of those infecting cruciferous hosts. All isolates from cruciferous crops produced microsclerotia, and the majority produced long conidia with a high nuclear DNA content; these isolates were divided into two groups by amplified fragment length polymorphism (AFLP) analysis.
