  • Research on the mechanism of delirium based on related serum biomarkers of the delirium

    Delirium is an acute cognitive disorder caused by a variety of factors which lead to cerebral cortical dysfunction. At present the studies on the pathophysiology of delirium is still very few. But studies on serum biomarker of delirium can help to elucidate the pathophysiological mechanism of delirium, and the studies are significant for delirium diagnosis, severity classification and prediction of long-term outcome. This review examines three major groups of delirium related serum biomarkers: ① risk markers: those that are present or elevated prior to disease onset, including serum chemistries, genetic markers and so on; ② disease markers: those markers elevate with delirium onset and fall when delirium recovery, including acetylcholine and serum anticholinergic activity, serotonin, serum amino acids, and melatonin, interleukin, C-reactive protein; and ③ end products: those that rise in proportion to the consequences of disease, including S-100ß and neuron specific enolase. The three markers mentioned above are helpful to further investigate the mechanism of delirium.

  • Effectiveness analysis of chronic disease continuous health management services based on a patient satisfaction survey

    Objective To investigate the satisfaction of patients who signed up for chronic disease continuous health management services, so as to provide a theoretical basis for improving service quality. Methods We conducted an online anonymous survey by issuing an electronic questionnaire to all patients who met the inclusion criteria through the short message platform of the hospital from October 8th to 19th, 2021, and used χ2 test and logistic regression to compare the differences in satisfaction among different patients and explore the factors affecting satisfaction. Results A total of 3311 short messages were send out, and 816 valid copies of questionnaire were recalled. The total satisfaction was 77.3%, and the satisfaction before, during and after service were 86.0%, 75.2% and 73.7%, respectively. The items with low satisfaction included service pricing (58.9%), online follow-up (57.5%) and overall cost reduction (43.9%). There were significant differences in satisfaction among patients of different permanent addresses and health status (P<0.05). The multiple binary logistic regression analysis showed that the respondents in Chengdu city had lower satisfaction than those outside Sichuan province [odds ratio (OR)=0.377, 95% confidence interval (CI) (0.156, 0.908), P=0.030], and the respondents with poor, general, and good self-reported health status had lower satisfaction than those with very good self-reported health status [OR=0.196, 95%CI (0.067, 0.577), P=0.003; OR=0.165, 95%CI (0.058, 0.468), P=0.001; OR=0.317, 95%CI (0.108, 0.927), P=0.036]. Conclusions The patients’ satisfaction with chronic disease continuous health management services is at a high level. The next step should focus on service pricing and online follow-up, and strive to improve the service experience of people with low satisfaction.

  • Analysis of the relationship of COVID-19 vaccination and critical cases of inpatients infected with Omicron variants

    ObjectiveTo analyze the correlation between the vaccination status of inpatients with Omicron variant infection and the risk of Omicron critical illness. MethodsA retrospective analysis was performed on the clinical data of patients with Omicron infection admitted to a designated hospital for COVID-19 in Chengdu from December 1, 2022 to January 31, 2023. Patients were divided into critical group and non-critical group according to their condition and the "COVID-19 Diagnosis and Treatment Program (Tenth Edition)". According to the vaccination status, the patients were divided into incomplete vaccination group, full vaccination group and booster vaccination group. Multivariate logistic regression was used to analyze the association between vaccination, symptoms and signs at admission, and the risk of critical illness. ResultsA total of 3 603 inpatients with Omicron infection were included, including 730 cases (20.3%) in the critical group and 2 873 cases (79.7%) in the non-critical group. There were 2 399 people (66.6%) in the incomplete vaccination group, 433 people (12%) in the full vaccination group, and 771 people (21.4%) in the booster vaccination group. Compared with the incomplete vaccination group, the proportion of critical illness in the full vaccination group and booster vaccination group was lower, and the critical illness rate increased with age (P<0.05). After adjusting for age, gender, and underlying diseases, the results of multivariate logistic analysis showed that full vaccination (OR=0.67, 95%CI 0.50 to 0.89) and booster vaccination (OR=0.76, 95% CI 0.61 to 0.94) were significantly associated with a reduced risk of critical illness. ConclusionFull vaccination and booster dose can effectively reduce the risk of critical illness after infection.

  • The application of electronic assessment tools for cognitive function

    As the aging of the population intensifies, the incidence of dementia continues to increase year by year. However, the general public's lack of awareness about dementia, combined with the complexity of the cognitive assessment process, often results in many dementia patients being diagnosed in the moderate to late stages of the disease, missing the crucial window for therapeutic intervention. This significantly affects the mental and physical health and quality of life of the elderly. With the continuous advancements in medical and information technology, the application of electronic tools in cognitive assessment is gradually increasing. This study summarizes the current application of electronic cognitive assessment tools to provide references for the development of electronic cognitive assessment tools suitable for the elderly in China.

  • Impact of evidence-based learning method on medical education: an overview of systematic reviews

    ObjectiveTo conduct an overview of systematic reviews on the impact of evidence-based learning (EBL) method on medical education. MethodsThe CNKI, WanFang Data, VIP, CBM, PubMed, Embase, Cochrane Library, and Web of Science databases were electronically searched to collect the relevant systematic reviews or meta-analyses of the application of EBL method in medical education from inception to May, 2024. Two researchers conducted the literature screening and data extraction independently. The AMSTAR 2, ROBIS tool, PRISMA 2020, and GRADE system were separately used to evaluate the methodological quality, the risk of bias, the quality of reporting, and the quality of evidence of included studies. ResultsA total of 16 systematic reviews/meta-analyses were included. The methodological quality evaluation by AMSTAR 2 showed that the quality level of 16 studies was very low. The results of ROBIS tool showed that 1 study was low risk of bias and 15 studies were high risk of bias. The GRADE evaluation of the evidence quality for 36 outcome indicators in the included studies revealed that 6 were of moderate quality, 12 were of low quality, and the rest were of very low quality. ConclusionEBL method has demonstrated significant effects in improving theoretical performance, practical skills, and critical thinking abilities among medical students. However, the methodological and evidence quality of the current systematic reviews/meta-analyses are low.

  • Application of regional citrate anticoagulation in continuous renal replacement therapy for patients with sepsis and hyperlactacidemia

    Objective To explore the application of regional citrate anticoagulation (RCA) in continuous renal replacement therapy (CRRT) for patients with sepsis and hyperlactacidemia, and to provide a basis for the clinical application of RCA in such patients. Methods Sepsis patients who underwent RCA-CRRT at West China Hospital of Sichuan University between May 2021 and May 2023 were retrospectively included. Patients were divided into a normal lactate group (≤2.0 mmol/L) and a hyperlactacidemia group (>2.0 mmol/L) based on their initial lactate levels before CRRT, and subgroup analysis was performed on patients with moderate hyperlactacidemia (2 mmol/L<lactate level<4 mmol/L) and severe hyperlactacidemia (≥4.0 mmol/L). Propensity score matching (PSM) was used, and baseline characteristics and outcome measures of different groups of patients were compared. Results A total of 441 patients were included, with 228 in the normal lactate group and 213 in the hyperlactacidemia group. Before PSM, there were statistically significant differences in the proportion of liver failure, proportion of chronic kidney disease, mean arterial pressure, bicarbonate, total bilirubin, creatinine, activated partial thromboplastin time, international standardized ratio, procalcitonin, and interleukin-6 between the normal lactate group and the hyperlactacidemia group (P<0.05). After PSM, there were 162 patients in both the normal lactate group and the hyperlactacidemia group. There was no statistically significant difference in baseline characteristics between the two groups of patients (P>0.05). The incidence of citric acid accumulation in the normal lactate group and the hyperlactacidemia group was 13.0% and 25.9%, respectively (P<0.05). There was no statistically significant difference in the incidence of metabolic acidosis, metabolic alkalosis, hypernatremia, filter coagulation events, or in-hospital mortality between the two groups (P>0.05). Kaplan-Meier survival analysis showed that there was no statistically significant difference in the first extracorporeal circulation lifespan between the normal lactate group and the hyperlactacidemia group (P>0.05). Among 213 patients with hyperlactacidemia, 186 had moderate hyperlactacidemia and 27 had severe hyperlactacidemia. Before PSM, there were statistically significant differences in the proportion of male, proportion of diabetes, albumin level, international standardized ratio, and interleukin-6 between moderate and severe hyperlactacidemia groups (P<0.05). After PSM, there were 22 patients in both the moderate and severe hyperlactacidemia groups. There was no statistically significant difference in baseline characteristics between the two groups of patients (P>0.05). The incidence of citric acid accumulation was 18.2% and 50.0% in the moderate and severe hyperlactacidemia groups, respectively (P<0.05). There was no statistically significant difference in the incidence of metabolic acidosis, metabolic alkalosis, hypernatremia, filter coagulation events, or in-hospital mortality between the two groups (P>0.05). Kaplan-Meier survival analysis showed that there was no statistically significant difference in the first extracorporeal circulation lifespan between the moderate and severe hyperlactacidemia groups (P>0.05). Conclusion When RCA is used for CRRT anticoagulation in patients with sepsis and hyperlactacidemia, the incidence of citric acid accumulation is high (especially in patients with severe hyperlactacidemia), and should be closely monitored.
