In the field of healthcare service, it is crucial to optimize medical innovation services by combining the preferences of health service providers and demanders (i.e., stakeholders). The best-worst scaling (BWS) method is a recently developed stated preference method for assessing preferences with distinctive advantages. Nevertheless, there is a lack of a comprehensive introduction to stakeholder preference assessment using BWS, thus constraining its applications and promotion. This paper introduces the process of using BWS to assess service providers' preferences for the Shared Medical Appointment for diabetes (SMART), an integrated healthcare service of medicine and health management, in the hope of providing reference for researchers for promoting the use of BWS in implementation research.

Objective To investigate risk factors of medication non-adherence in elderly patients with hypertension through Meta-analysis.Methods Literatures on medication non-adherence in elderly patients with hypertension were systematically reviewed across various databases,from inception to September 1st 2023,including CNKI,VIP,Wangfong Database,SinoMed,PubMed,Web of Science,Cochrane Library、EMbase.Meta-analysis was conducted using RevMan 5.4.Results A total of 19 articles were included,comprising a total of 18 220 patients in sample size.Meta analysis identified 10 risk factors,showed significant association(P<0.05)with:age[OR=1.36,95%CI=(1.00,1.86)],place of residence[OR=1.91,95%CI=(1.33,2.75)],method of payment for medical expenses[OR=1.60,95%CI=(1.38,1.86)],income level[OR=1.68,95%CI=(1.45,1.95)],occupational status[OR=1.79,95%CI=(1.37,2.36)],social support[OR=1.43,95%CI=(1.27,1.60)],comorbidity[CI=0.33,95%(0.19,0.58)],frequency of blood pressure measurement[CI=1.53,95%(1.14,2.05)],disease awareness[OR=1.70,95%CI=(1.44,2.00)]and dedication frequency[OR=1.44,95%CI=(1.16,1.79)].In addition,the number of influencing factors such as gender,marital status,depression,cognitive impairment,and complications was included in<3 articles,and only descriptive analysis was conducted.Conclusion Healthcare providers should focus on the identification and management of the risk factors associated with medication non-adherence in elderly patients with hypertension,therefore to reduce the incidence of medication non-adherence.

Background/Aims: Despite the high efficacy of direct-acting antivirals (DAAs), approximately 1–3% of hepatitis C virus (HCV) patients fail to achieve a sustained virological response. We conducted a nationwide study to investigate risk factors associated with DAA treatment failure. Machine-learning algorithms have been applied to discriminate subjects who may fail to respond to DAA therapy. Methods: We analyzed the Taiwan HCV Registry Program database to explore predictors of DAA failure in HCV patients. Fifty-five host and virological features were assessed using multivariate logistic regression, decision tree, random forest, eXtreme Gradient Boosting (XGBoost), and artificial neural network. The primary outcome was undetectable HCV RNA at 12 weeks after the end of treatment. Results: The training (n=23,955) and validation (n=10,346) datasets had similar baseline demographics, with an overall DAA failure rate of 1.6% (n=538). Multivariate logistic regression analysis revealed that liver cirrhosis, hepatocellular carcinoma, poor DAA adherence, and higher hemoglobin A1c were significantly associated with virological failure. XGBoost outperformed the other algorithms and logistic regression models, with an area under the receiver operating characteristic curve of 1.000 in the training dataset and 0.803 in the validation dataset. The top five predictors of treatment failure were HCV RNA, body mass index, α-fetoprotein, platelets, and FIB-4 index. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the XGBoost model (cutoff value=0.5) were 99.5%, 69.7%, 99.9%, 97.4%, and 99.5%, respectively, for the entire dataset. Conclusions Machine learning algorithms effectively provide risk stratification for DAA failure and additional information on the factors associated with DAA failure.

OBJECTIVE To observe the effects of chlorogenic acid on the activation of macrophage induced by lipopolysaccharide （LPS）， and to explore the role of triggering receptors expressed on myeloid cells-2 （TREM2） in the action. METHODS To find a suitable LPS concentration， the cells were cultured with 1， 10 and 100 ng/mL LPS for 24 h. The level of interleukin 6 （IL-6） in the cell culture supernatant and protein expression of inducible nitric oxide synthase （iNOS） in the cells were detected. To search for a suitable chlorogenic acid concentration， the cells were divided into control group， LPS group and three chlorogenic acid （0.01， 0.1 and 1 μmol/L）+LPS groups. The levels of tumor necrosis factor α （TNF-α） and IL-1β in the cell culture supernatant， the protein expressions of iNOS and TREM2 in the cells and cell viability were detected. To observe the effects of TREM2 in chlorogenic acid alleviating macrophage activation， TREM2-small interfering RNA （TREM2-siRNA） was taken to intervene in TREM2 protein expression. The cells were divided into control group， LPS group， chlorogenic acid+LPS group， TREM2-siRNA+chlorogenic acid+LPS group and SC-siRNA+chlorogenic acid+LPS group. After 24 h incubation， the levels of TNF- α and IL-1β in the cell culture supernatant and protein expressions of TREM2， iNOS and nuclear factor κB p65 （NF-κB p65） in the cells were detected. RESULTS 10 ng/mL LPS promoted IL-6 release and increased iNOS protein expression， and 10 ng/mL LPS was taken in the next experiments. Compared with the LPS group， 0.1 μmol/L chlorogenic acid decreased TNF-α jiaji1981@126.com and IL-1β levels， and down-regulated iNOS expression，meanwhile increased TREM2 expression without effect on cell viability， and 0.1 μmol/L chlorogenic acid was taken in the next experiments. Compared with the control group， the protein expressions of iNOS and NF- κB p65 in the LPS group were significantly increased （P＜0.05）； compared with the LPS group， the protein expressions of iNOS and NF- κB p65 in the chlorogenic acid+LPS group were significantly decreased， the protein expressions of TREM2 was significantly increased （P＜ 0.05）； compared with the chlorogenic acid+LPS group， the protein expressions of iNOS and NF-κB p65 of TREM2-siRNA+ chlorogenic acid+LPS group were significantly increased， the protein expressions of TREM2 was significantly decreased （P＜0.05）. TREM2-siRNA could significantly reverse the above effects of chlorogenic acid， while SC-siRNA did not significantly affect the above anti-inflammatory effects of chlorogenic acid. CONCLUSIONS Chlorogenic acid can inhibit the LPS-induced macrophage activation， and its anti-inflammatory may be mediated by TREM2 protein.

Objective Constructing physiological-psycho-social three dimensional aging index system, and scale to provide a basis for evaluating the effects of human aging and anti-aging measures. Methods Evaluation, modification and determination of the second and third level indexed by Delphi and principal component analysis and other methods. The weight of each index was weighted by the analytic hierarchy process, and the reliability and validity were calculated on the basis of the preliminary scale. A large sample of empirical studied to determine the aging of different age groups standardized score distribution table. The best model for judging functional age was sought, based on a variety of biostatistical models. Results The aging scale was constructed by three levels, the first level included 3 indicators, the second level had 10 indicators, the third level included 51 indicators, and adopted by expert certification the national society. 3 184 valid questionnaires were obtained through epidemiological investigation, the average total score of aging was (46.93±11.07) points, and the scores of aging were positively correlated with age(r=0.785, P<0.001). The average scores of aging in each dimension were different and the difference was statistically significant (all P<0.001), and each dimension had significant difference with age. The growth model (R2=0.635) was selected, the curve of the relationship between the score of aging and age was fitted. Conclusions The three-dimensional human aging scale was scientific, feasible, and has good reliability and validity. The empirical results show that the comprehensive score of aging increase with age, and show certain characteristics and laws on the curve.

OBJECTIVE: To study and compare the effect of indwelling drainage tube and extubation time on occult hemorrhage and functional recovery after total hip arthroplasty(THA). METHODS: From July 2017 to June 2018, 123 patients who underwent THA in our hospital for the first time were selected as the subjects of study. According to whether the drainage tube was retained or not and the time of extubation, they were divided into three groups:in group A, 41 patients (24 males, 17 females, age 53 to 77 years) did not put drainage tube after THA;in group B, 41 patients were removed 24 hours after THA, 26 males and 15 females, aged 55 to 74 years;in group C, 41 patients were removed 48 hours after THA, 25 males and 16 females, aged 52 to 75 years. The VAS score of pain 72 hours after THA, the total and recessive blood loss, the time of starting functional exercise, and the incidence of postoperative limb swelling were recorded. All the patients were followed up for one year after discharge. Harris hip score was used to evaluate the degree of hip function recovery one year after operation. RESULTS: The occult blood loss of group A, B and C were(513.6±25.3), (521.7±33.4), (519.3±29.8) ml, respectively, with no significant difference(>0.05). There was no significant difference in blood loss in operation among the three groups(>0.05). In group B and C, the postoperative apparent blood loss was more than that in group A (<0.05). There was no significant difference in VAS scores of the three groups before and 72 hours after operation (>0.05). The time of getting out of bed in group A was shorter than that in group B and C (<0.05), and that in group B was shorter than that in group C(<0.05). The Harris hip score at 1 year after operationof the three groups was significantly higher than that of before operation (<0.05). There was no significant difference in Harris hip score before and after operation among three groups (>0.05). There was no significant difference in the incidence of complications among three groups (>0.05). CONCLUSION Whether the drainage tube is left or not and the time of extubation have no significant effect on the latent blood loss and functional recovery after THA, but without drainage tube after THA can reduce the apparent blood loss, patients can get out of bed at 6 hours after THA, which is more conducive to the recovery and nursing of patients.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.
