Culturally and linguistically diverse (CALD) communities are growing globally. Understanding patterns of cerebrovascular disease in these communities may improve health outcomes. We aimed to compare the rates of transient ischaemic attack (TIA), ischaemic stroke (IS), intracerebral haemorrhage (ICH), intracranial atherosclerosis (ICAD), and stroke risk factors in Vietnamese-born residents of South-Western Sydney (SWS) with those of an Australian-born cohort. A 10-year retrospective analysis (2011-2020) was performed using data extracted from the Health Information Exchange database characterising stroke presentations and risk factor profiles. The rates of hypertension (83.7% vs. 70.3%, < 0.001) and dyslipidaemia (81.0% vs. 68.2%, < 0.001) were significantly higher in Vietnamese patients, while the rates of ischaemic heart disease (10.4% vs. 20.3%, < 0.001), smoking (24.4% vs. 40.8%, < 0.001), and alcohol abuse (>1 drink/day) (9.6% vs. 15.9%, < 0.001) were lower. The rates of ICAD and ICH were higher in Vietnamese patients (30.9% vs. 6.9%, < 0.001 and 24.7% vs. 14.4%, = 0.002). Regression analysis revealed that diabetes (OR: 1.86; 95% CI: 1.14-3.04, = 0.014) and glycosylated haemoglobin (OR: 1.51; 95% CI: 1.15-1.98, = 0.003) were predictors of ICAD in Vietnamese patients. Vietnamese patients had higher rates of symptomatic ICAD and ICH, with unique risk factor profiles. Culturally specific interventions arising from these findings may more effectively reduce the community burden of disease.

We report a rare case of splenic tuberculosis (TB) in a male patient with a competent immune system who had no previous record of pulmonary TB. A 56-year-old male patient came to our outpatient department complaining of upper abdominal pain with a few episodes of vomiting for three days. He had alcoholism, smoked for 15 years, and had no past history of diabetes mellitus, hypertension, TB, or HIV. An abdominal ultrasound and CT scan at admission showed pancreatitis with a splenic abscess. After five days of admission, the patient's vitals deteriorated, and he had severe abdominal pain. CT scan suggested a splenic abscess rupture with hemoperitoneum. An emergency exploratory laparotomy was performed, and a splenectomy was done due to the splenic abscess rupture. A cartridge-based nucleic acid amplification test from splenic intracapsular fluid detected a trace complex. The patient was discharged after starting first-line antitubercular treatment for six months. After three months of follow-up, the patient was doing well with no complaints.

BACKGROUND
Clinic-based interventions are needed to promote successful direct acting antiviral (DAA) treatment for chronic hepatitis C virus (HCV) infection in patients with substance use disorders (SUDs) among rural Veterans.
METHODS
We implemented a clinic-based intervention which used motivational interviewing (MI) techniques to promote medication adherence and treatment completion with 12 weeks of DAA treatment among rural Veterans with chronic HCV and SUDs. Patients received an MI session with a licensed psychologist at baseline and at each two-week follow-up visit during DAA treatment. Patients received $25 per study visit completed. Patients were to attend a laboratory visit 12 weeks after treatment completion to assess for sustained virologic response (SVR).
RESULTS
Of the 20 participants who enrolled, 75% (n = 15) completed the planned 12-week course of treatment. Average adherence by pill count was 92% (SD = 3%). Overall SVR was 95% (19/20).
CONCLUSIONS
We demonstrated that a clinic-based intervention which incorporated frequent follow up visits and MI techniques was feasible and acceptable to a sample of predominantly rural Veterans with chronic HCV and SUDs.

The calcium calmodulin protein kinase II (CaMKII) is a multi-subunit ring assembly with a central hub formed by the association domains. There is evidence for hub polymorphism between and within CaMKII isoforms, but the link between polymorphism and subunit exchange has not been resolved. Here, we present near-atomic resolution cryogenic electron microscopy (cryo-EM) structures revealing that hubs from the α and β isoforms, either standalone or within an β holoenzyme, coexist as 12 and 14 subunit assemblies. Single-molecule fluorescence microscopy of Venus-tagged holoenzymes detects intermediate assemblies and progressive dimer loss due to intrinsic holoenzyme lability, and holoenzyme disassembly into dimers upon mutagenesis of a conserved inter-domain contact. Molecular dynamics (MD) simulations show the flexibility of 4-subunit precursors, extracted in-silico from the β hub polymorphs, encompassing the curvature of both polymorphs. The MD explains how an open hub structure also obtained from the β holoenzyme sample could be created by dimer loss and analysis of its cryo-EM dataset reveals how the gap could open further. An assembly model, considering dimer concentration dependence and strain differences between polymorphs, proposes a mechanism for intrinsic hub lability to fine-tune the stoichiometry of αβ heterooligomers for their dynamic localization within synapses in neurons.

Review
Chronic liver inflammation, a pervasive global health issue, results in millions of annual deaths due to its progression from fibrosis to the more severe forms of cirrhosis and hepatocellular carcinoma (HCC). This insidious condition stems from diverse factors such as obesity, genetic conditions, alcohol abuse, viral infections, autoimmune diseases, and toxic accumulation, manifesting as chronic liver diseases (CLDs) such as metabolic dysfunction-associated steatotic liver disease (MASLD), metabolic dysfunction-associated steatohepatitis (MASH), alcoholic liver disease (ALD), viral hepatitis, drug-induced liver injury, and autoimmune hepatitis. Late detection of CLDs necessitates effective treatments to inhibit and potentially reverse disease progression. However, current therapies exhibit limitations in consistency and safety. A potential breakthrough lies in nanoparticle-based drug delivery strategies, offering targeted delivery to specific liver cell types, such as hepatocytes, Kupffer cells, and hepatic stellate cells. This review explores molecular targets for CLD treatment, ongoing clinical trials, recent advances in nanoparticle-based drug delivery, and the future outlook of this research field. Early intervention is crucial for chronic liver disease. Having a comprehensive understanding of current treatments, molecular biomarkers and novel nanoparticle-based drug delivery strategies can have enormous potential in guiding future strategies for the prevention and treatment of CLDs.

Missouri's Overdose Field Report (ODFR) is a community-based reporting system which intends to capture overdoses which may not be otherwise recorded. Describe the factors related to non-fatal overdoses reported to Missouri's ODFR. This study used a descriptive epidemiological approach to examine the demographics and circumstances of overdoses reported to the ODFR. We used binary logistic regression to evaluate factors associated with survival and ordinal logistic regression to evaluate factors associated with number of doses used. Factors were chosen based on their relevance to overdose education and survival, and naloxone distribution. Between 2018 and 2022, 12,225 overdoses (67% male; 78% White) were reported through the ODFR, with a 96% (n = 11,225) survival rate. Overdose survival (ps < .02) was associated with younger age (OR = .58), no opioid and stimulant co-involvement (OR = .61), and private location (OR = .48). Intramuscular naloxone in particular was associated with a significantly higher odds of survival compared to nasal naloxone (OR = 2.11). An average of 1.6 doses of naloxone per incident were administered. Additional doses were associated (ps < .02) with being older (OR = .45), female (OR = .90), nasal naloxone (versus intravenous) (OR = .65), and the belief fentanyl was present (OR = 1.49). Our reporting form provides a comprehensive picture of the events surrounding reported overdoses, including factors associated with survival, how much naloxone was used, and the effects of respondents believing fentanyl was involved. Missouri's report can provide support for current naloxone dosing, contextualize refusing post-overdose transport, and can be used to improve overdose response by community and first responders.

BACKGROUND
Alcohol use disorder (AUD) is a major economic and healthcare burden in the United States. While there is evidence-based medication-assisted treatment (MAT) for AUD, few physicians implement these therapies on a regular basis.
OBJECTIVE
To determine the impact of a pharmacy-guided AUD discharge planning workflow on the rate of MAT prescriptions and inpatient readmissions.
METHODS
This was a single-centered pre-and-post intervention study over a 6-month period, with a 90-day pre-intervention period and a 90-day post-intervention period. The study included all patients over the age of 18 years admitted to a medicine or surgery floor bed who presented with alcohol withdrawal at any point during their hospital course. The intervention involved a pharmacy workflow, in which a list of patients admitted with alcohol withdrawal was automatically generated and referred to pharmacists, who then provided recommendations to the primary physician regarding prescriptions for naltrexone, acamprosate, and/or gabapentin. The patients were then contacted within 30 days after discharge for post-hospitalization follow-up. Our outcome measures were change in prescription rate of MATs, change in total and alcohol-related 90-day readmission rates, and change in total and alcohol-related 90-day emergency department (ED) visit rates.
RESULTS
The pre-intervention period consisted of 49 patients and the post-intervention period consisted of 41 patients. Our workflow demonstrated a 195% increase in the prescription rate of MATs at discharge (p < 0.001), 61% reduction in 90-day total readmission rate (p < 0.05), 40% reduction in 90-day total ED visit rate (p = 0.09), 92% reduction in 90-day alcohol-related readmission rate (p < 0.05), and 88% reduction in 90-day alcohol-related ED visit rate (p < 0.05).
CONCLUSIONS
Our intervention demonstrated that a pharmacy-based AUD discharge planning workflow has the potential to reduce inpatient readmissions and ED visits for patients with AUD, thus demonstrating improved patient outcomes with the potential to reduce healthcare costs.

It is known that cannabis use affects memory and sleep problems independently. However, to date, how memory and sleep problems may interact as a result of cannabis use remains unknown. We performed a secondary analysis of existing data to determine whether sleep quality mediates the association between cannabis use and memory and whether sex moderated these effects. A total of 141 adults with cannabis use disorder (CUD) (83 men) and 87 without CUD (39 men) participated in this study. Outcome measures included self-reported sleep problems from the past 7 days (Marijuana Withdrawal Checklist), learning and memory performance via the short visual object learning task (sVOLT), short visual object learning task delayed (sVOLTd), and verbal memory via the N-back. Bootstrapped mediation and moderated mediation analyses were run to test if sleep quality mediated the association between cannabis use and memory outcomes and whether sex moderated these effects, respectively. Sleep quality mediated the effect of group (i.e. adults with and without CUD) on sVOLT efficiency scores (indirect effect ß = -.08, 95% CI [-0.14, -0.04]) and sVOLTd efficiency scores (indirect effect ß = -.09, 95% CI [-0.14, -0.04]), where greater sleep difficulties was associated with poorer memory performance (decreased efficiency scores). Sex did not moderate these relationships. These initial findings of a mediating role of sleep in the association between CUD and visual learning memory highlight potential critical downstream effects of disrupted sleep in those with CUD and suggest the importance of investigating sleep in CUD.

OBJECTIVE
To determine the background, bacteriological, clinical and radiological findings, associated lesions, treatment and outcome of splenic abscesses (SAs) in infective endocarditis (IE).
METHODS
Retrospective study (2005-2021) of 474 patients with definite IE. The diagnosis of SA was made in 36 (7.6%) patients (31, 86.1%, males, mean age = 51.3) on abdominal CT.
RESULTS
The main implicated organisms were Streptococcus spp (36.1%), Enterococcus faecalis (27.7%), Staphyloccus spp (19.4%). Rare agents were present in 10 patients (27.8%). Pre-existing conditions included a prosthetic valve (19.4%), previous IE (13.9%), intravenous drug use (8.4%), diabetes (25%) alcohol abuse (13.9%), liver disease (5.5%). Vegetations ≥ 15 mm were present in 36.1%. Common presentations were abdominal pain (19.4%) and left-sided pleural effusion (16.5%). SA were more often small (50%; 7 multiple) than large (36.1%; 1 multiple) or microabscesses (13.9%, 3 multiple). Associated complications were extrasplenic abscesses (brain, 11.1%; lung, 5.5%; liver, 2.8%), infectious aneurysms (16.7%: 3 intracranial, 1 splenic, 1 hepatic, 1 popliteal), emboli (brain, 52.8%; spleen, 44.4%, 5 evolving to SA; kidney, 22.2%; aorta, 2.8%), osteoarticular infections (25%). Twenty-eight (77.8%) patients only received antimicrobials, 7 (19.4%) underwent splenectomy, after cardiac surgery in 5. One had percutaneous drainage. The outcome was uneventful (follow-up 3 months-14 years; mean: 17.2 months).
CONCLUSION
In SA-IE patients, the prevalence of vegetation size, Enterococcus faecalis, rare germs, diabetes, osteo-arthritic involvement and cancer was higher than in non-SA patients. Some SAs developed from splenic infarcts. IE-patients with evidence of splenic emboli should be evaluated for a possible abcedation. Cardiac surgery before splenectomy was safe.

Review
Various countries and US States have legalized cannabis, and the use of the psychoactive and non-psychoactive cannabinoids is steadily increasing. In this review, we have collated evidence from published non-clinical and clinical sources to evaluate the abuse, dependence and associated safety risks of the individual cannabinoids present in cannabis. As context, we also evaluated various synthetic cannabinoids. The evidence shows that delta-9 tetrahydrocannabinol (Δ-THC) and other psychoactive cannabinoids in cannabis have moderate reinforcing effects. Although they rapidly induce pharmacological tolerance, the withdrawal syndrome produced by the psychoactive cannabinoids in cannabis is of moderate severity and lasts from 2 to 6 days. The evidence overwhelmingly shows that non-psychoactive cannabinoids do not produce intoxicating, cognitive or rewarding properties in humans. There has been much speculation whether cannabidiol (CBD) influences the psychoactive and potentially harmful effects of Δ-THC. Although most non-clinical and clinical investigations have shown that CBD does not attenuate the CNS effects of Δ-THC or synthetic psychoactive cannabinoids, there is sufficient uncertainty to warrant further research. Based on the analysis, our assessment is cannabis has moderate levels of abuse and dependence risk. While the risks and harms are substantially lower than those posed by many illegal and legal substances of abuse, including tobacco and alcohol, they are far from negligible. In contrast, potent synthetic cannabinoid (CB1/CB2) receptor agonists are more reinforcing and highly intoxicating and pose a substantial risk for abuse and harm. "Psychoactive" is defined as a substance that when taken or administered affects mental processes, e.g., perception, consciousness, cognition or mood and emotions.
