Objective: This study aimed to investigate the effects of preoperative low-dose esketamine and dexmedetomidine nasal administration on the incidence of postoperative emergence delirium in children undergoing fiber bronchoscopy.

Methods: A total of 129 patients, of any gender, aged 1 to 6 years, with ASA grades I and II, who were scheduled for fiber bronchoscopy, were randomly divided into three groups (n = 43) using a random number table method: 1.0 mg/kg of esketamine, 1.0 μg/kg of dexmedetomidine, and an equal volume of normal saline (group control). The respective dose of the drug or normal saline was rapidly instilled through both nostrils using a 1-mL syringe. The primary outcome measure was the incidence of emergence delirium. The secondary outcome measures included postoperative pain intensity, time to awaken and open eyes in the postanesthesia care unit, incidence of postoperative adverse behavior, hemodynamics, and duration of stay in the postanesthesia care unit.

Results: A total of 126 patients completed the study, and compared with the group control (48.78%), the 1.0 mg/kg esketamine (7.14%) and 1.0 μg/kg dexmedetomidine (18.6%) had a lower incidence of postoperative emergence delirium ( P < 0.01), as well as lower postoperative pain intensity ( P < 0.01). However, compared with the group control, the 1.0 μg/kg dexmedetomidine had a prolonged time to awaken and open eyes in the postanesthesia care unit ( P < 0.05). The duration of hemodynamics, oral secretion volume, and stay in the postanesthesia care unit were similar among the three groups.

Conclusions: The findings suggest that low-dose esketamine and dexmedetomidine can reduce the incidence of emergence delirium.

Objectives: Proton pump inhibitors (PPIs) are widely used to reduce gastric acid levels and are often prescribed with antiplatelet agents in patients with stroke. However, the interactions and differences among various PPIs remain unclear. Therefore, we aimed to compare the differences between esomeprazole and ilaprazole in patients with and without stroke. We also compared the effects of aspirin use in the ilaprazole group.

Methods: We retrospectively analyzed 580 patients with neurological disorders who responded to the Gastroesophageal Reflux Disease Questionnaire at a tertiary hospital between October 2020 and December 2023. Comparative and subgroup analyses were performed using the chi-squared test, Fisher's exact test, and t tests.

Results: In the overall patient cohort, patients using esomeprazole had lower rates of dyslipidemia and lower white blood cell, hemoglobin, triglyceride, and low-density lipoprotein cholesterol levels, compared to ilaprazole users. However, among patients with stroke, esomeprazole users had higher rates of atrial fibrillation and lower triglyceride, hemoglobin, and uric acid levels, compared to ilaprazole users. In the ilaprazole group, nonaspirin users were younger and had fewer stroke episodes and higher total cholesterol levels, compared to aspirin users. Furthermore, patients using antiplatelet and PPI therapies and antacids had lower hemoglobin levels, compared to antacid nonusers.

Conclusions: Significant differences existed between esomeprazole and ilaprazole users and among ilaprazole users based on aspirin use. Therefore, careful monitoring of PPI use with antiplatelet agents and antacids is recommended in patients with neurological disorders. However, further research is needed to understand these differences and their clinical impact.

Objective: The aim of the study was to assess the characteristics and outcomes of adults with attention-deficit/hyperactivity disorder (ADHD) and a previous history of restrictive eating disorder symptoms.

Method: We retrospectively reviewed the health records of patients with ADHD and a history of disordered eating who were treated at our institution with medications that have potential anorexiant properties from October 1, 2022, through March 31, 2024.

Results: We initially identified 159 patients who were referred to an ADHD program at our institution during the study period. Of 72 patients who met criteria for an ADHD diagnosis, 18 had SCOFF questionnaire scores of 2 or higher, which suggests symptoms of a restrictive eating disorder. Of these 18 patients, 3 had a previous diagnosis of an eating disorder documented in their health records. Each patient was treated with medications chosen to manage their reported ADHD symptoms, regardless of eating disorder concerns. All patients had improvements in ADHD symptoms without reporting adverse effects on disordered eating behaviors. Body weight and body mass index values did not significantly change after treatment with atomoxetine, dextroamphetamine/amphetamine, or methylphenidate (all P ≥ 0.14).

Conclusions: Our findings are consistent with those of previous reports and suggest that ADHD treatment, including treatment with stimulant medications, is safe and tolerable for patients with a history of restrictive eating disorder symptoms.

Objectives: Animal studies have suggested that valproic acid (VPA) is neuroprotective in aneurysmal subarachnoid hemorrhage (SAH). However, the effect of VPA on SAH outcomes in humans has not been investigated.

Methods: We conducted a retrospective analysis of 123 patients with nontraumatic SAH. Eighty-seven patients had an aneurysmal source and 36 patients had no culprit lesion identified. We used stepwise logistic regression to determine the association between VPA and delayed cerebral ischemia (DCI), radiographic vasospasm, and discharge modified Rankin Scale (mRS) score >3.

Results: All 18 patients who received VPA underwent coil embolization of their aneurysm. VPA use did not have a significant association with DCI on adjusted analysis (odds ratio [OR] = 1.07, 95% confidence interval [CI]: 0.20-5.80). The association between VPA use and vasospasm was OR = 0.64 (0.19-1.98) and discharge mRS > 3 was OR = 0.45 (0.10-1.64). Increased age (OR = 1.04, 1.01-1.07) and Hunt and Hess grade >3 (OR = 14.5, 4.31-48.6) were associated with poor discharge outcome (mRS > 3). Younger age (OR = 0.96, 0.93-0.99), modified Fisher Scale (mFS) score = 4 (OR = 4.14, 1.81-9.45), and Hunt and Hess grade >3 (OR = 2.92, 1.11-7.69) were all associated with development of radiographic vasospasm. There were no complications associated with VPA administration.

Conclusions: We did not observe an association between VPA and the rate of DCI. We found that VPA use was safe in SAH patients who have undergone endovascular treatment of their aneurysm.

Objectives: People with diabetes are 1.5 times more likely to experience stroke than those without diabetes, underlining the urgent need to address this issue. Metformin is often the initial medication chosen to manage diabetes mellitus (DM). The purpose of our systematic review and meta-analysis is to explore the potential neuroprotective effects of metformin in individuals who have received it prior to stroke.

Method: Our study encompassed cohort studies that drew a comparison between the severity and diverse outcomes of stroke among individuals with DM who were administered metformin prior to the stroke event and those with DM who did not receive the treatment.

Results: Ten studies met the eligibility criteria. Prestroke metformin use was associated with a significantly lower National Institutes of Health Stroke Scale score (mean difference = -1.29, 95% confidence interval: -2.11 to -0.47) in ischemic stroke. Metformin pretreatment in ischemic stroke was associated with increased odds of favorable outcome (mRS < 2) at 90 days (odds ratio [OR] = 1.45, 95% confidence interval [CI]: 1.06 to 1.99), but it was not significant at discharge. Metformin was found to be associated with reduced mortality (OR = 0.52, 95% CI: 0.42 to 0.64) in ischemic stroke. In hemorrhagic stroke, the results showed a significantly lower intracranial hemorrhage volume in prestroke metformin use (mean difference = -4.77, 95% CI: -6.56 to -2.98).

Conclusions: We found that prestroke metformin use in diabetic patients yielded neuroprotective effects. In ischemic strokes, metformin reduces stroke severity and 90-day mortality; it also improves 90-day functional outcomes. In hemorrhagic strokes, prestroke metformin use can also cause less intracranial hemorrhage volume. Further clinical trials are needed to confirm its efficacy and verify its benefits in stroke management.

Objectives: Impulsivity is thought to be a core feature of gambling disorder, yet little is known as to whether trait impulsivity predicts treatment response.

Methods: Data were pooled from 2 previous randomized controlled pharmacological trials using naltrexone and N-acetyl cysteine.

Results: Trait impulsivity statistically explained variation in medication treatment response ( P = 0.0260, R2 = 0.26). Higher baseline motor impulsiveness was associated with greater treatment response ( P = 0.009).

Conclusions: Measures of impulsivity may thus be important to include in future large-scale datasets, in trial settings but also routine clinical gambling clinic practice, toward building predictive algorithms that may ultimately help to inform optimal treatment choices and improve outcomes.

Objectives: This study reviews literature on the psychiatric effects of delta-8-THC, particularly psychosis and severe mental health outcomes, to highlight the need for further research and regulation.

Background: Marijuana, the most widely used illicit drug in the United States, sees increasing use due to legalization. Although moderate use is generally safe, adverse effects can occur, especially in those with preexisting conditions. Delta-9-THC is known for its psychoactive effects and potential to induce psychosis. Delta-8-THC, another cannabinoid, is gaining popularity and has been linked to severe adverse events but remains under-researched.

Methods: A comprehensive search of PubMed and Web of Science followed PRISMA guidelines to identify studies and case reports on delta-8-THC and psychosis. Articles on delta-9-THC or other cannabinoids were excluded. Relevant studies were screened, and duplicates removed. The included studies were evaluated using the Critical Appraisal Skills Programme Checklist for Case Reports.

Results: The search identified 201 studies, with 12 meeting the inclusion criteria for full-text analysis. Six case reports, involving 9 patients, were reviewed. Most patients were male and in their 20s, with varied psychiatric histories, including no prior psychiatric history, schizophrenia, posttraumatic stress disorder, and generalized anxiety disorder. Reported symptoms included psychosis, mood lability, and cannabinoid hyperemesis syndrome. Treatments varied, with different clinical outcomes.

Conclusions: Delta-8-THC poses significant psychiatric risks despite being less intoxicating than delta-9-THC. The lack of Food and Drug Administration regulation and the availability of delta-8-THC products heighten these risks. More rigorous studies are needed to understand delta-8-THC's impact on mental health and inform regulatory actions.

Objectives: Traditional antidepressant therapy is associated with an inadequate response and a low remission rate. Our aim was to synthesize published randomized controlled trials on the potential effects of minocycline in patients with depression.

Methods: PubMed, Web of Science, Embase, and Cochrane Library databases were searched for studies published. Randomized controlled trials published in English that evaluated the efficacy of minocycline in patients with depression were selected for inclusion. Changes from baseline in the Hamilton Depression Rating Scale (HDRS) or Montgomery-Åsberg Depression Rating Scale (MADRS) were pooled to determine the antidepressant effect of minocycline compared with placebo. The quality of the included studies was assessed using the Cochrane risk-of-bias tool.

Results: Eight trials with 567 participants were eligible and included in the analysis. The meta-analysis did not reveal a statistically significant effect of minocycline on depression based on HDRS or MADRS scores.

Conclusions: According to the HDRS and MADRS scores, minocycline did not demonstrate effectiveness in reducing depressive symptoms.

Introduction: Adjunctive therapies to treat OFF episodes resulting from long-term levodopa treatment in Parkinson disease (PD) are hampered by safety and tolerability issues. Istradefylline offers an alternative mechanism (adenosine A2A receptor antagonist) and therefore potentially improved tolerability.

Methods: A systematic review of PD adjuncts published in 2011 was updated to include randomized controlled trials published from January 1, 2010-April 15, 2019. Pairwise meta-analyses were updated, and Bucher indirect comparisons were used to generate estimates of relative safety, presented as odds ratio (OR) and 95% confidence interval (CI) for comparators versus istradefylline.

Results: Fifty-seven randomized controlled trials involving 11,517 patients were included in the meta-analysis. Relative to istradefylline, dopamine agonists and catechol-O-methyl transferase (COMT) inhibitors had statistically significant higher odds of dyskinesia and somnolence. Monoamine oxidase-B inhibitors had significantly higher odds of hypotension. Amantadine extended-release (ER) had statistically significant higher odds of hallucination, orthostatic hypotension, insomnia, and withdrawals due to adverse events. All interventions combined had significantly higher odds of dyskinesia versus istradefylline 20 mg and somnolence versus istradefylline 40 mg. Considering overall incidence of adverse events, COMT inhibitors and amantadine ER had statistically significant higher odds versus both istradefylline doses (COMT versus istradefylline 40 mg, OR: 1.33; 95% CI: 1.03, 1.75; versus istradefylline 20 mg, OR: 1.32; 95% CI: 1.01, 1.72; amantadine ER versus istradefylline 40 mg, OR: 3.45; 95% CI: 1.85, 6.25; versus istradefylline 20 mg, OR: 3.33; 95% CI: 1.82, 6.25).

Conclusion: Istradefylline was associated with a generally favorable safety profile relative to other adjunct medications in this study.
