Being male and having cocaine identified in the toxicological test were the factors that showed a strong association with abusive alcohol beverage consumption in suicide victims. Other factors showed a slight association (PR < 1.5) having an education level with greater than 8 years of study, being black, having a professional occupation or being retired or pensioner, and having the presence of cannabis in the toxicological test.

Socioeconomic-demographic and behavioral factors proved to be positively associated with abusive alcoholic beverage consumption among suicide victims, suggesting the need for effective public health policy measures to combat this health problem.

Policy evaluations and health system interventions often utilize International Classification of Diseases (ICD) codes of opioid use, dependence, and abuse to identify individuals with opioid use disorder (OUD) and assess receipt of evidence-based treatments. However, ICD codes may not map directly onto the Diagnostic and Statistical Manual of Mental Disorder (DSM-5) OUD criteria. This study investigates the positive predictive value of ICD codes in identifying patients with OUD.

We conducted a clinical chart review on a national sample of 520 Veterans assigned ICD-9 or ICD-10 codes for opioid use, dependence, or abuse from 2012 to 2017. We extracted evidence of DSM-5 OUD criteria and opioid misuse from clinical documentation in the month preceding and three months following initial ICD code listing, and categorized patients into 1) high likelihood of OUD, 2) limited aberrant opioid use, 3) prescribed opioid use without evidence of aberrant use, and 4) insufficient information. Positive predictive value was calculated as the percentage of individuals with these ICD codes meeting high likelihood of OUD criteria upon chart review.

Only 57.7 % of patients were categorized as high likelihood of OUD; 16.5 % were categorized as limited aberrant opioid use, 18.9 % prescribed opioid use without evidence of aberrant use, and 6.9 % insufficient information.

Patients assigned ICD codes for opioid use, dependence, or abuse often lack documentation of meeting OUD criteria. Many receive long-term opioid therapy for chronic pain without evidence of misuse. Robust methods of identifying individuals with OUD are crucial to improving access to clinically appropriate treatment.

MicroRNAs act as crucial regulators of a diverse range of biological processes, including chemoresistance. Our study aimed to investigate the effect of miR-324-3p on lung adenocarcinoma cell line A549 resistant to cis-diamminedichloroplatinum II (DDP, aka cisplatin).

The miR-324-3p expression levels in cisplatin-sensitive A549（A549） and cisplatin-resistant A549 (A549/DDP) cells were determined by qRT-PCR assay. Cell proliferation was determined with the commercial kit CCK-8 and colony formation assay, whereas cell death was analyzed using flow cytometry. The target gene of miR-324-3p was identified and validated with the luciferase reporter and western blot assays. The role of miR-324-3p in modulating cisplatin resistance was evaluated invitro.

The expression of miR-324-3p was found to be significantly downregulated in the A549/DDP cells. Conversely, miR-324-3p overexpression reversed cisplatin resistance in the cells. With regard to the possible mechanism underlying this phenomenon, we identified the glutathione peroxidase 4 (GPX4) gene as the direct target of miR-324-3p, where overexpression of the gene reversed the miR-324-3p effect of sensitizing the A549/DDP cells to cisplatin. Furthermore, the GPX4 inhibitor RSL3 could mimic the effect of miR-324-3p upregulation in increasing the sensitivity of the cisplatin-resistant cells to the drug. Significantly, miR-324-3p enhanced cisplatin-induced ferroptosis in the A549/DDP cells.

Our findings revealed the role of the miR-324-3p-GPX4 signaling axis in A549/DDP cells and how the targeting of this axis could be a potential strategy for reversing cisplatin resistance in human non small cell lung cancer (NSCLC).

To study the effects of CX3CR1 on white matter injury, neurofunction, recognition, and expression of the CD36/15LO/NR4A1 signal in mice with traumatic brain injury (TBI).

CX3CR1
, CX3CR1
and C57BL/6 male mice were randomly divided into 3 groups. We used a controlled cortical impact (CCI) to establish a TBI model and T2wt MRI to detect the TBI lesion. FA and DTI allowed for quantitative evaluation of the structural integrity of white matter tracts. Several behavior tests were used to investigate nerve function; a computer-based tracing system was used to trace and analyze dendrites and cell bodies of microglia and astrocytes in the peri-lesional brain areas. We also used RT-PCR and western blot to detect the effect of CX3CL1/CX3CR1 axis on CD36/15LO/NR4A1 signal.

The fractional anisotropy (FA) at the corpus callosum area of brain was decreased at 3 days post TBI, the average lesion volume CX3CR1
