A comparison between constructed wetland substrates: Impacts on microbial community and wastewater treatment.

Constructed wetlands (CWs) can play a crucial role in treating wastewater, and in the context of this study, the distillation byproduct of the whisky industry known as 'spent lees'. Here, we assess several different CW substrates (pea gravel, LECA and Alfagrog), with and without the addition of 20% biochar, in mesocosms set up to treat spent lees. Among the substrates tested, LECA + biochar and gravel + biochar showed promising results, with greater dissolved copper (dissCu) reduction, chemical oxygen demand (COD) removal, organic carbon (OC) reduction, and pH modulation.

Evidence-based treatment for opioid use disorder is widely unavailable and often discouraged by providers of residential substance use services in North Carolina.

Introduction: Opioid agonist treatment (OAT) is the only treatment for opioid use disorder (OUD) proven to reduce overdose mortality, yet access to this evidence-based treatment remains poor. The purpose of this cross-sectional audit study was to assess OAT availability at residential substance use services in North Carolina.

Methods: We conducted a state-wide inventory of residential substance use service providers in North Carolina and subsequently called all providers identified, posing as uninsured persons who use heroin, seeking treatment services.

Patterns of Self-Reported Mental Health Symptoms and Treatment among People Booked into a Large Metropolitan County Jail.

The Brief Jail Mental Health Screen (BJMHS) is one of the most well-known and frequently used tools to conduct routine mental health screening at jail intake. In prior research, the BJMHS results typically have been evaluated overall (i.e.
