Purpose: Despite significant advancements in the treatment of acute ischemic stroke (AIS) with endovascular thrombectomy (EVT), post-EVT mortality remains a considerable concern. However, there is a lack of real-world epidemiological data delineating the characteristics of mortality for EVT, particularly in recent years following the widespread promotion of EVT treatment for stroke patients.

Methods: This multicenter, retrospective study collected data from 721 AIS patients who died following EVT across 33 hospitals in Sichuan Province, China, from January 2019 to September 2022. The analysis sought to identify the primary causes of death within 30 days post-EVT and explore their related clinical features.

Results: The leading causes of death were malignant cerebral edema (MCE) in 365 patients (50.6%), pneumonia in 180 patients (25%), and symptomatic intracranial hemorrhage (sICH) in 94 patients (13%). MCE was the predominant cause of death in anterior circulation strokes, while pneumonia prevailed in posterior circulation strokes. MCE was also the primary cause of death within one week post-EVT, but pneumonia became increasingly dominant over time. Large vessel occlusion and lower reperfusion success rate were significantly correlated with MCE. Advanced age increases the risk of death from pneumonia. Tandem occlusion and procedural complications tend to correlate with mortality from sICH.

Conclusion: This study revealed that the principal causes of death after EVT included MCE, sICH, and pneumonia. MCE was found to be correlated with unsuccessful reperfusion. sICH was associated with procedural complications and the operators' experience. Pneumonia was linked to post-EVT management, particularly for those who survived for one week.

Background: Remimazolam, a novel ultra-short-acting benzodiazepine, shows promise for procedural sedation. This study compared the cognitive recovery of remimazolam versus propofol in elderly patients undergoing colonoscopy.

Patients and methods: In this prospective, randomized, double-blind, controlled trial, 228 patients aged ≥ 65 years undergoing outpatient colonoscopies were recruited. Patients received intravenous sufentanil 0.05 μg/kg, followed by either remimazolam 0.2 mg/kg or propofol 1 mg/kg for sedation induction. The assigned study drug (remimazolam 0.1 mg/kg or propofol 0.5 mg/kg) was titrated to maintain a Modified Observer's Assessment of Alertness/Sedation scale score < 3 during the procedure. The primary outcome was the incidence of cognitive recovery, assessed using the Postoperative Quality of Recovery Scale (PostopQRS) cognitive domain on postoperative day 3. Secondary outcomes included overall and other PostopQRS domains recovery, time to discharge, patient satisfaction, and adverse events.

Results: Cognitive recovery on day 3 was similar between remimazolam (84.2%) and propofol (85.1%) groups (risk ratio = 0.99; 95% CI: 0.89-1.11; p = 0.854). No significant differences were observed in overall recovery, other domains, or discharge time. Remimazolam patients reported higher satisfaction (p = 0.001) and experienced lower incidences of hypotension (21.9% vs 53.5%; p < 0.001), hypoxemia (6.1% vs 16.7%; p = 0.024), and injection site pain (15.8% vs 41.2%; p < 0.001) compared to propofol.

Conclusion: In elderly patients undergoing colonoscopy, remimazolam demonstrated comparable cognitive recovery to propofol, with higher patient satisfaction and a more favorable safety profile. Remimazolam may be the preferred alternative to propofol for procedural sedation in this vulnerable population.

Purpose: In the present study, the findings related to the epidemiology, clinical presentation, and therapeutic outcomes of elderly patients treated with transoral laser microsurgery (TOLM) and transoral robotic surgery (TORS) for supraglottic laryngeal squamous cell carcinoma (LSCC) have been reviewed.

Methods: A PubMed, Cochrane Library, and Scopus literature search was conducted according to the PRISMA statements. Critical literature analysis was carried out considering the last advancement in TOLS and TORS, and their related surgical, functional, and survival outcomes.

Findings: The mean age of patients with supraglottic LSCCs has progressively increased in the past decades. The data on postoperative complications in elderly patients with LSCC are heterogeneous and contradictory. The thought of the age-related high risk of complications was based on open supraglottic laryngectomy (SGL), but not on TOLM and TORS findings, which do not support an age-related increase of most postoperative complications. The only complication that could be associated with age is aspiration. The adequate selection of patients undergoing TOLM or TORS, and the pre- to postoperative evaluation of swallowing function can prevent this risk. The OS of elderly patients treated with TOLM or TORS SGL could be lower compared to younger patients. However, the disease-free survival was not influenced by age, highlighting the role of comorbidities and intercurrent diseases in the presumed lower survival. The survival analysis could definitively consider the physiological age rather than the chronological age to investigate the impact of age on survival outcomes.

Conclusion: The current literature supports an important place of TOLM and TORS in managing cT1-T3 supraglottic LSCC. The preoperative geriatric, nutritional, and swallowing evaluations are important for ensuring an adequate selection of patients treated with TORS or TOLM SGL.

Background: Previous studies have demonstrated a significant correlation between obstructive sleep apnea (OSA) and frailty. However, the association of mean pulse oxygen saturation (MSpO₂) with frailty among OSA patients remains unconfirmed. This study aimed to explore this potential association using data from a multicenter, prospective cohort.

Methods: A total of 1006 elderly patients diagnosed with OSA through polysomnography (PSG) from January 2015 to October 2017 were enrolled. Patients were stratified into four groups according to their MSpO₂ levels to assess differences in frailty onset. Multivariate Cox regression analysis, Kaplan-Meier curves, restricted cubic splines, and subgroup analyses were employed to evaluate variations in frailty onset across different MSpO₂ levels.

Results: Over a median follow-up period of 52 months, 275 patients developed frailty. Analysis using restricted cubic splines revealed a U-shaped trend between MSpO₂ and frailty risk (non-linear p-value = 0.028). Patients in the lowest quartile (MSpO₂ < 91.6%) exhibited a higher risk of frailty (hazard ratio [HR] = 1.43, 95% confidence interval [CI] 1.03-1.97, P = 0.029) compared to those in the third quartile (MSpO₂ 93-95%). Subgroup and sensitivity analyses confirmed the robustness of the U-shaped relationship.

Conclusion: There is a U-shaped association between MSpO₂ and frailty among patients with OSA. Enhancing MSpO₂ levels may mitigate the risk of frailty and improve prognosis in this population.

Background: Behavioral and psychological symptoms of dementia (BPSD), as neuropsychiatric manifestations within dementia, constitute core features of dementia. However, there remains a gap in understanding the recognition of BPSD in China. Our current study was to explore the clinical awareness and treatment approaches for BPSD in China, focusing especially on the perspectives of neurologists and psychiatrists.

Methods: A multicenter national survey was designed and a semi-structured questionnaire was distributed to healthcare professionals including doctors and nurses across all provinces of China. The questionnaire incorporated either closed (yes/no) and multiple-choice questions. The questions centered on the following areas: the perceived global frequency and relevance of BPSD; the assessment tools employed for evaluating BPSD; pharmacological approaches for addressing psychosis, apathy, agitation, aggression, depression, anxiety, sleep, and nutrition disorders; drug-related side effects; non-pharmacological treatment strategies. The anonymity of questionnaire responses was maintained to encourage participants to candidly express their viewpoints.

Results: The majorities of respondents recognized the importance of BPSD. There were apparent differences in the perception of BPSD between neurologists and psychiatrists, encompassing variances in symptoms recognition, diagnostic approaches, and treatment strategies. A notable high percentage of neurology (27.8%) and psychiatry staff (23.6%) would not choose non-pharmacological interventions. Meanwhile, antipsychotics was overused in China. For aggression and agitation, more than half of neurologist and psychiatrist preferred antipsychotics. For psychosis, more than 80% of doctors chose antipsychotics. Nearly one-third of the medical staff expressed a preference for traditional Chinese medicine including ginkgo biloba extract.

Conclusion: In summary, this study in China has shed light on the features related to perception, recognition, management, treatment options, and observed side effects associated with BPSD. Our findings have the potential to significantly enhance the understanding of BPSD characteristics among medical practitioners and offering valuable insights into improved management and treatment strategies of neuropsychic symptoms of dementia in China.
