Background: Traditional treatment approaches for prescription-type opioid use disorder (POUD), centered on abstinence, have limitations and hinder the development of interventions that meet the needs of people with POUD. Reduction in use without complete abstinence presents a promising avenue for intervention enhancement, but supporting data is scarce regarding its translation into positive patient outcomes. This study explores whether reducing opioid use frequency (OUF) during opioid agonist treatment correlates with reduced potential life problems in individuals with POUD, including those using fentanyl.
Methods: This study is an exploratory analysis of the OPTIMA trial, a pragmatic, open-label, randomized controlled study comparing the effectiveness of flexible take-home dosing of buprenorphine/naloxone and supervised methadone in reducing opioid use amongst individuals with POUD. OUF was assessed every two weeks for 24 weeks after treatment initiation using the Timeline Followback. Potential life problems were evaluated at baseline and study completion using the Addiction Severity Index Self-Report. The 114 participants who completed both baseline and end-of-study questionnaires were included. A repeated-measures generalized linear mixed model (GLMM) was used to evaluate the influence of OUF on potential life problems.
Results: Reducing OUF was significantly associated with fewer problems related to medical status (p = 0.049), psychiatric status (p = 0.019), and alcohol problem severity (p = 0.001). The interaction was non-significant for employment (p = 0.264), family status (p = 0.352) and legal status (p = 0.050). Life improvements emerged with ≤ 21 days of opioid use per 28-day period.
Conclusion: Findings underscore the significance of harm reduction goals focusing on opioid use reduction, which translated in improvements across many life domains.
Trial Registration: Study was registered with ClinicalTrials.gov (NCT03033732) prior to participant enrollment.

Detoxifying reactive oxygen species (ROS) that accumulate under saline conditions is crucial for plant salt tolerance. The Salt Overly Sensitive (SOS) pathway functions upstream, while flavonoids act downstream, in ROS scavenging under salt stress. However, the potential crosstalk between the SOS pathway and flavonoids in regulating salt stress responses and the associated mechanisms remain largely unexplored.

Citrus fruits, known for their vibrant flavours and health benefits, are susceptible to fungal attacks, particularly from toxigenic fungi, which pose a significant pre- and post-harvest hazard. However, aromatic oils and their nanoparticles may effectively address this issue. Marjoram and fennel oils, alongside their nanoparticles, were extracted, and their aromatic constituents and antimicrobial activities were evaluated.

The emergence and rapid spread of multidrug-resistant strains pose a great challenge to the quality and safety of agricultural products and the efficient use of pesticides. Previously unidentified fungicides and targets are urgently needed to combat -associated infections as alternative therapeutic options. In this study, the promising compound Z24 demonstrated efficacy against all tested plant pathogenic fungi.

Extracellular vesicles (EVs), including exosomes, mediate intercellular communication by transporting functional molecules between donor cells and recipient cells, thereby regulating biological processes, such as immune responses. miR-451a, an immune regulatory microRNA, is highly abundant in circulating EVs; however, its precise physiological significance remains to be fully elucidated. Here, we demonstrate that miR-451a deficiency exacerbates delayed-type hypersensitivity (DTH) in mice.

Chronic infections with hepatitis E virus (HEV), especially those of genotype 3 (G3), frequently lead to liver fibrosis and cirrhosis in patients. However, the causation and mechanism of liver fibrosis triggered by chronic HEV infection remain poorly understood. Here, we found that the viral multiple-domain replicase (ORF1) undergoes unique ubiquitin-proteasomal processing leading to formation of the EV-erived MAD ctivator (HDSA), a viral polypeptide lacking putative helicase and RNA polymerase domains.
