A new study published in Science Direct looked at how different dimensions of precarious employment affects mental health. “This is a study that analyzes the relationship between job insecurity and mental health in a Spanish territory (the Basque Country),” study author Erika Valero told us. “Considering the importance of paid work as a social determinant of health, we expected that also in our context, this problem could be related to mental health.” [More]

A new study published in the NeuroReport for Rapid Communication of Neuroscience Research looked at high-frequency ultrasound exposure and whether it could improve depressive-like behavior in an olfactory bulbectomized rat model of depression. “It is well known that whole-body exposure to high frequency ultrasound increases brain activity in humans,” study author Akiyoshi Saitoh. “However, little is known about its impact and associated mechanisms on emotional states like depression. In the present study, we demonstrated the anti-depressant effects of ultrasound exposure in a rodent model of depression.” [More]

A new study published in Neurology, the medical journal of the American Academy of Neurology looked at physical and mental activity, disease susceptibility, and risk of dementia. “In the present study, we aimed to assess the associations between physical and mental activity and the subsequent risk of dementia,” study author Huan Song told us. “We further hoped to explore whether such associations would differ for individuals with different susceptibility to dementia.” [More]

Having a partner was more beneficial at avoiding loneliness during the first wave of COVID-19 than having children. Research published in the European Journal of Ageing found that whilst those without children and those without a partner were more likely to be lonely, those without a partner underwent a notable shift in their loneliness in the early stages of the pandemic.

A new study published in the National Library of Medicine looked at gender and sex differences in urban greenness’ mental health benefits. “Our study examines articles that investigate the relationship between mental health outcomes and urban greenness with a deeper look into gender and sex differences associated with them as well as how gender and sex are used in environmental health literature,” study author Marta-Beatriz Fernandez Nunez told us.

Fatigue is associated with anxiety and depression in patients with long COVID. Research published in the Journal of Neurology found that fatigue was correlated with cognitive deficits as well as neuropsychiatric conditions, like depression. [More]

A new study published in the American Society for Microbiology Journal looked at the long-term effects of developmental exposure to oxycodone on gut microbiota and the relationship to adult behaviors and metabolism. “In this study, we sought to determine whether exposure of mouse moms to a widely prescribed and abuse opioid drug, oxycodone, would lead to longstanding effects on the bacteria in the gut and whether such changes might be associated with behavioral and metabolic alterations also seen in these adult sons and daughters,” study author Cheryl S. Rosenfeld told us. [More]

A new study in the works published in the BMJ Open is looking at community-engaged mental health promotion intervention with Bhutanese people resettled in Western Massachusetts. The current research project will be among the first to adapt and pilot test the feasibility and acceptability of a family-based, community-led, culturally tailored, integrated preventative behavior intervention to reduce immigrant stress. The study will lay the basis for a clinical trial with a large, adequately powered sample. If effective, this community-engaged intervention may be applied more widely to other immigrants and the general population. [More]

A new study published in JAMA looked at the long-term risk of overdose or mental health crisis after opioid dose tapering. “We have published results showing that opioid tapering after long-term stable dosing was associated with overdose and mental health crisis events during a one-year follow-up period,” study author Joshua J. Fenton told us. “We wanted to assess the longer-term outcomes associated with tapering.” [More]

A new study published in Current Psychiatry Reports looked at substance use among youth during the COVID-19 pandemic. “The study investigates the question of whether or not substance use has increased or decreased in the youth population during the pandemic,” study author Hannah M. Layman told us. “There are many reasons why both are possible (for example: increasing due to coping strategies or decreasing due to increased time with family). Our study aimed to analyze existing literature to best answer this question. I personally was unsure of what we might find.” [More]
