Objective To systematically review the willingness to use pre-exposure prophylaxis (PrEP) and its influencing factors among men who have sex with men (MSM) in China. Methods We conducted a comprehensive search on various databases, including China National Knowledge Infrastructure, VIP database, Wanfang data, China Biomedical Literature Service System, PubMed, Web of Science, Cochrane Library, and Embase, covering the period from database inception to September 6th, 2023. We focused on studies that publicly reported data on the willingness to use PrEP and its influencing factors among MSM in China. The quality of included studies was assessed using the quality evaluation criteria recommended by the Agency for Healthcare Research and Quality. RevMan 5.3 software and Stata 13.1 software were used to perform meta-analysis for the willingness to use PrEP and its influencing factors among MSM in China. Results A total of 24 cross-sectional studies with 19 influencing factors and a sample size of 16499 participants were included in the review. The results revealed a PrEP usage intention rate of 60.4% [95% confidence interval (CI) (51.8%, 68.9%)] among the MSM population in China. Factors such as awareness of PrEP [odds ratio (OR)=5.26, 95%CI (1.33, 20.82)], having heard of PrEP [OR=1.84, 95%CI (1.28, 2.64)], age<25 years [OR=1.92, 95%CI (1.34, 2.77)], being a student [OR=1.92, 95%CI (1.17, 3.16)], monthly income of 1000-3000 yuan [OR=1.36, 95%CI (1.12, 1.65)], history of human immunodeficiency virus (HIV) testing [OR=2.05, 95%CI (1.53, 2.74)], history of sexually transmitted infections [OR=1.75, 95%CI (1.27, 2.40)], seeking sexual partners online [OR=1.38, 95%CI (1.19, 1.59)], openness about sexual orientation [OR=1.90, 95%CI (1.27, 2.84)], having a non-local household registration [OR=1.66, 95%CI (1.37, 2.02)], and recommending PrEP to friends [OR=20.14, 95%CI (2.59, 156.91)] were identified as promoting factors for the willingness to use PrEP. Conversely, a homosexual orientation [OR=0.67, 95%CI (0.52, 0.85)] was identified as a barrier to the willingness to use PrEP. Conclusions Chinese MSM have a low intention to use PrEP, and there are many factors affecting the intention to use PrEP in MSM. In the future HIV prevention and control work, measures such as strengthening education and publicity of PrEP, providing a certain degree of support for PrEP costs, strengthening health education on campus, strengthening community organizations and support networks should be taken to promote the willingness of MSM to use PrEP.
Objective To explore the current situation and influencing factors of self-management behavior in patients with primary glaucoma, so as to provide a theoretical basis for formulating intervention strategies to improve patients’ self-management ability. Methods Using convenient sampling method, 400 patients with primary glaucoma visiting the Outpatient Department of Ophthalmology, West China Hospital of Sichuan University between September 2019 and March 2020 were selected. Their current situation of self-management behavior was investigated by self-management behavior questionnaire, and the influencing factors of self-management behavior were analyzed. Results A total of 381 valid questionnaires were recovered. The total score of self-management behavior of patients with primary glaucoma was 51.11±6.22, and the mean scores of life debugging dimension, functional health care dimension, and medical management dimension were 2.66±0.67, 3.02±0.81, and 3.13±0.60, respectively. The results of multiple linear regression analysis showed that age [40-59 vs. <40 years old: unstandardized partial regression coefficient (b)=–2.830, 95% confidence interval (CI) (–4.813, –0.847), P=0.005; ≥60 vs. <40 years old: b=–2.660, 95%CI (–4.820, –0.498), P=0.016], occupation [in-service vs. farmers: b=2.639, 95%CI (0.303, 4.976), P=0.027; unemployed or retired vs. farmers: b=2.913, 95%CI (0.995, 4.831), P=0.003], smoking [smoking vs. non-smoking: b=–3.135, 95%CI (–5.196, –1.075), P=0.003], disease type [primary open-angle glaucoma vs. primary angle-closure glaucoma: b=–2.119, 95%CI (–3.317, –0.921), P=0.001], number of follow-up visits [≤2 vs. >2: b=–1.071, 95%CI (–2.118, –0.024), P=0.045], whether fixed doctor follow-up [unfixed vs. fixed: b=–2.619, 95%CI (–3.632, –1.605), P<0.001] were correlated with the total score of self-management behavior of patients with primary glaucoma. Conclusions The self-management behavior of patients with primary glaucoma is in the middle level. The main factors affecting the self-management behavior level of primary glaucoma patients include age, occupation, smoking, disease type, follow-up times, and fixed doctor’s follow-up. Ophthalmologists should pay attention to the current situation and influencing factors of self-management behavior and take feasible intervention measures to improve the self-management behavior of patients with primary glaucoma.
Objective To explore the influencing factors of inhalation medication compliance in Chinese asthma patients, and to provide evidence for improving the compliance of patients with inhalation therapy. Methods PubMed, China National Knowledge Infrastructure, Wanfang, Chongqing VIP, and SinoMed were searched for literature on factors influencing inhalation medication compliance in Chinese asthma patients from the establishment of databases to December 2021. Meta-analysis was performed using RevMan 5.2 software. Results A total of 16 studies were included, with a sample size of 2 600 cases, 1 084 cases of good compliance with inhalation administration, 1 516 cases of poor compliance with inhalation administration, and good compliance with inhalation administration accounted for 41.69%. The literature quality evaluation scores were all ≥4 points, all of which were of medium quality and above. Meta-analysis showed that the factors affecting inhalation compliance of asthma patients included age [odds ratio (OR)=0.54, 95% confidence interval (CI) (0.32, 0.91), P=0.02], educational level [OR=0.57, 95%CI (0.36, 0.90), P=0.02], doctor-patient relationship [OR=0.42, 95%CI (0.19, 0.93), P=0.03], disease severity [OR=0.25, 95%CI (0.11, 0.58), P=0.001], degree of mastery of asthma knowledge [OR=2.51, 95%CI (1.11, 5.65), P=0.03], degree of mastery of inhalation technique [OR=8.66, 95%CI (3.20, 23.40), P<0.0001], adverse drug reaction [OR=0.23, 95%CI (0.13, 0.41), P<0.00001]. Conclusion The compliance of inhaled dosing in Chinese asthma patients needs to be improved urgently. Age, education level, doctor-patient relationship, disease severity, mastery of asthma knowledge, mastery of inhalation technology, and adverse drug reactions are the important influencing factors of inhaled medication compliance.
Objective To analyze the benign-malignant outcomes of pulmonary nodules in surgical patients and their influencing factors, and provide evidence and ideas for optimizing and improving the integrated management model of pulmonary nodules. Methods From October to December 2023, a convenience sampling method was used to select patients who underwent lung surgery at West China Hospital, Sichuan University between July 2022 and June 2023 for this study. The malignancy rate of postoperative pathological results of pulmonary nodules and its influencing factors were analyzed using univariate analysis and multiple logistic regression. Results A total of 4600 surgical patients with pulmonary nodules were included, with a malignancy rate of 88.65% (4078/4600) and a benign rate of 11.35% (522/4600). Univariate analysis showed significant differences in malignancy rates among different genders, ages, methods of pulmonary nodule detection, and smoking histories (P<0.05); however, no significant difference was found regarding place of birth or family history of lung cancer (P>0.05). Multiple logistic regression analysis indicated that females [odds ratio (OR)=1.533, 95% confidence interval (CI) (1.271, 1.850)], older age groups [61-75 vs. ≤30 years: OR=1.640, 95%CI (1.021, 2.634); >75 vs. ≤30 years: OR=2.690, 95%CI (1.062, 6.814)], and pulmonary nodules detected during physical examinations [OR=1.286, 95%CI (1.064, 1.554)] were high-risk factors for malignancy, with statistical significance (P<0.05). Conclusion In the integrated management of pulmonary nodules, it is crucial not to overlook females or older patients, as they may be more significant influencing factors than smoking; furthermore, lung examinations are effective means of early detection of malignant lung tumors and are worth promoting and popularizing.
Objective To investigate the current situation of salivation in patients with orotracheal cannula, and to systematically analyze its influencing factors. Methods Patients who underwent tracheal intubation treatment in 47 tertiary comprehensive medical institutions were selected between October 10th and 20th, 2023. A cross-sectional survey method was used to conduct an online survey of the patient’s salivation status. The patients were divided into the salivation group and no-salivation group. Results A total of 565 questionnaires were collected and 561 were valid, with an effective recovery rate of 99%. Among 561 patients, 284 were males (50.62%) and 277 were females (49.38%), with an age of (59.80±10.96) years; 159 cases of salivation occurred, with a total static saliva flow rate of (7.21±3.15) mL and the incidence of salivation was 28.34% (159/561). There were statistically significant differences in age, education level, body mass index, primary disease, number of concurrent functional impairments, concurrent oral diseases, smoking, intubation days, intubation depth, intubation process, sedation and/or analgesia days, and enteral nutrition treatment between the two groups (P<0.05). There was no statistically significant difference in other indicators between the two groups (P>0.05). The results of multivariate logistic regression analysis showed that body mass index, neurological diseases, number of concurrent functional impairments, concurrent oral diseases, smoking, intubation days and intubation process were independent risk factors for salivation in patients with oral catheterization. Conclusion The incidence of salivation in patients with orotracheal cannula is 28.34%, which is directly related to body mass index, neurological diseases, number of concurrent functional impairments, concurrent oral diseases, smoking, intubation days and intubation process.
Objective To explore the influencing factors for pulmonary infection after radical resection of colon cancer. Methods A cohort study included 56 patients who underwent radical resection of colon cancer in People’s Hospital of Daye City from Oct. 2014 to Oct. 2016 were followed-up prospectively, to observe the occurrence of pulmonary infection, and collectting the related factors for pulmonary infection in addition. Results The clinical data of 53 patients were finalized and the clinical data of these patients were complete. Among them, 13 patients suffered from pulmonary infection after radical resection of colon cancer, and 40 patients had no obvious exacerbation and no complicated pulmonary infection. Results of logistic regression showed that, value of forced expiratory volume in1 second/forced vital capacity (OR=1.174, P=0.033), operative time (OR=1.638, P=0.012), levels of postoperative copeptin (OR=1.328, P=0.032), and procalcitonin (OR=1.465, P=0.042) were risk factors for pulmonary infection after radical resection of colon cancer. Receiver operating characteristic curve (ROC) showed that, operative time was 6.207-hour, postoperative copeptin level was 10.420 pmol/L, and the postoperative procalcitonin level was 3.676 ng/mL, which had the best predictive effect on predicting pulmonary infection after radical resection of colon cancer. Conclusions Value of forced expiratory volume in 1 second/forced vital capacity, operative time, levels of copeptin and procalcitonin after operation are the independent influencing factors for pulmonary infection after radical resection of colon cancer, and it has best prognostic outcome when the operative time is 6.207-hour, postoperative copeptin level is 10.420 pmol/L, and the postoperative procalcitonin level is 3.676 ng/mL.
Objective To investigate the prevalence of cognitive impairment and identify its influencing factors among lung cancer patients undergoing chemotherapy, providing a scientific basis for targeted interventions. Methods A convenience sample of lung cancer patients receiving chemotherapy at West China Hospital, Sichuan University between April and October 2024 was enrolled. Data were collected using a general information questionnaire, the Mini-Mental State Examination, Nutritional Risk Screening 2002, Hospital Anxiety and Depression Scale, Barthel index, and FRAIL scale. Univariate analyses and multivariate logistic regression were performed to determine factors associated with cognitive impairment. Results A total of 380 patients undergoing chemotherapy for lung cancer were enrolled, and 205 (53.9%) of them had cognitive impairment. Univariate analyses revealed that there were statistically significant differences between the cognitively normal group and the cognitive impairment group in age, educational level, work status, nutritional status, Barthel index, and FRAIL scale score (P<0.05). Multivariate logistic regression showed that advanced age [odds ratio (OR)=1.045, 95% confidence interval (CI) (1.015, 1.075), P=0.002] and FRAIL scale score [OR=1.369, 95%CI (1.165, 1.609), P<0.001] were identified as independent risk factors for cognitive impairment, whereas higher educational attainment served as a protective factor, compared with patients with primary school education or below, patients with junior high school, high school/secondary vocational school, college, or undergraduate education and above had a lower risk of cognitive impairment [OR=0.437, 0.258, 0.243, 0.120, P<0.05]. Conclusions Cognitive impairment is highly prevalent among lung cancer patients undergoing chemotherapy and is significantly influenced by age, educational level, and frailty. Healthcare providers should develop targeted interventions based on these factors to reduce the prevalence of cognitive impairment.
Objective To explore the overall outcome and its factors of patients with carbapenem-resistant Pseudomonas aeruginosa bloodstream infection (CRPA-BSI). Methods A single-center, retrospective cohort study was carried out. The demographic and clinical data of all emergency patients and inpatients in West China Hospital of Sichuan University from 2017 to 2021 were collected. Firstly, the prognosis of patients with CRPA-BSI was compared with those with carbapenem-sensitive Pseudomonas aeruginosa bloodstream infection (CSPA-BSI). Then Cox regression was used to analyze the factors affecting the prognosis of CRPA-BSI patients. Results A total of 53 patients with CRPA-BSI and 175 patients with CSPA-BSI were enrolled, and they were 1∶1 matched according to the age-adjusted Charlson Comorbidity Index (aCCI) to control for confounding factors. When aCCI was similar, the incidence of poor prognosis in CRPA-BSI patients was significantly higher than that in CSPA-BSI patients [41.5% vs. 18.9%; relative risk=2.20, 95% confidence interval (CI) (1.16, 4.19), P=0.011]. The median length of hospital stay in the CRPA-BSI group was 3 d longer than that in the CSPA-BSI group but the difference was not statistically significant (29 vs. 26 d, P=0.388). With regard to prognostic factors, univariate Cox regression analyses showed that the highest temperature ≤39℃ (P=0.014), hepatobiliary and pancreatic diseases (P=0.011), days of central venous catheterization (P=0.025), days of indwelling urinary catheters (P=0.037), adjustment of medication duration according to drug sensitivity results (P=0.015) and Pitt bacteremia score (P=0.007) were related to the poor prognosis of CRPA-BSI patients. Multiple Cox regression analysis showed that hepatobiliary and pancreatic disease [hazard ratio (HR)=3.434, 95%CI (1.271, 9.276), P=0.015] and Pitt bacteremia score [HR=1.264, 95%CI (1.057, 1.510), P=0.010] were independently associated with poor outcome in CRPA-BSI patients. Conclusions The prognosis of CRPA-BSI patients is worsen than that of CSPA-BSI patients. Hepatobiliary and pancreatic diseases significantly increase the risk of poor outcome in CRPA-BSI patients. Pitt bacteremia score is a predictor of prognosis in patients with CRPA-BSI.
Objective To investigate the risk factors of chronic obstructive pulmonary disease (COPD) combined with obstructive sleep apnea (OSA) and its relationship with apnea-hypopnea index (AHI). Methods Clinical data of 216 COPD patients with OSA were retrospectively chosen in the period from January 2016 to December 2019 in our hospital. All patients were divided into different groups according to with or without OSA and the clinical features of patients with and without OSA were compared. Multivariate analysis was used to analyze the influencing factors of COPD with OSA and the correlation between AHI and COPD with OSA was also evaluated. Results ① The age, body mass index (BMI), neck circumference, smoking index, forced expiratory volume in 1 second (FEV1), FEV1% predicted (FEV1pred), the ratio of FEV1 to the forced vital capacity of the lungs (FEV1/FVC), COPD assessment test (CAT) score, Epworth sleepiness scale (ESS) score, Charlson comorbidity index (CCI) score, sleep apnea clinical score (SACS) score and proportion of patients with essential hypertension in OSA group were significantly higher than non-OSA group (P<0.05). The course of disease and the proportion of severe COPD and GOLD grade 4 in OSA group were significantly less than non-OSA group (P<0.05). ② AHI was positively correlated with age, BMI, neck circumference, smoking index, FEV1%pred, FEV1%pred<50%, CAT score, ESS score, CCI score and SACS score (P<0.05); and negatively correlated with FEV1%pred<50% (P<0.05). ③ Multivariate analysis showed that BMI, FEV1%pred<50%, CAT score and ESS score were the independent factors of COPD patients with OSA (P<0.05). ④ The proportion of AHI<5 times/h in GOLD grade 4 was significantly higher than GOLD grade 1-3 (P<0.05). The proportion of AHI> 30 times/h in GOLD grade 4 was significantly lower than GOLD grade 1-3 (P<0.05). Conclusion The incidence of COPD with OSA was independently correlated with BMI, FEV1%pred, CAT score and ESS score; patients with severe COPD possess lower OSA risk.
ObjectiveTo explore the trajectories of health-related quality of life (HRQoL) among adolescents after metabolic bariatric surgery and to identify influencing factors. MethodsThis retrospective cohort study included 208 adolescents who underwent metabolic bariatric surgery at the First Affiliated Hospital of Nanjing Medical University from June 2023 to December 2024. Data on quality of life were collected at baseline, 3 months, and 6 months postoperatively, along with related scale assessments at 6 months. Latent class growth modeling was applied to identify trajectory categories of quality of life. Demographic characteristics and scale points were compared across groups, and unordered multinomial logistic regression was used to analyze influencing factors. ResultsThree distinct HRQoL trajectories were identified by latent class growth model: low-level improvement group (102 cases, 49.0%), moderate-level stable group (74 cases, 35.6%), and high-level decline group (32 cases, 15.4%). Significant differences were observed among groups in BMI, percentage of excess weight loss (EWL%), points of body image, self-esteem, objective support, support utilization and appearance anxiety index at 6 months after operation (P<0.05). At 6 months postoperatively, patients in the low-level improvement group had the lowest BMI and the highest EWL%, along with higher body image and support utilization points. Patients in the moderate-level stable group experienced less weight reduction than those in the low-level improvement group, with only limited improvement in quality of life. Although patients in the high-level decline group initially had better preoperative quality of life, they showed the least postoperative weight loss, the lowest body image and support utilization points, and higher appearance anxiety points, with a progressive decline in quality of life. Results of unordered multinomial logistic regression analysis indicated that postoperative BMI, EWL%, points of body image, and support utilization were influencing factors associated with HRQoL trajectories (P<0.05). ConclusionsMetabolic bariatric surgery improves quality of life in most adolescents, yet a subgroup experiences unfavorable trajectories. Postoperative weight loss, body image, and social support are critical determinants. Early identification and targeted interventions are needed to optimize long-term outcomes.
