Résumé
OBJECTIVE@#Current clinical evidence on the effects of home blood pressure telemonitoring (HBPT) on improving blood pressure control comes entirely from developed countries. Thus, we performed this randomized controlled trial to evaluate whether HBPT plus support (patient education and clinician remote hypertension management) improves blood pressure control more than usual care (UC) in the Chinese population.@*METHODS@#This single-center, randomized controlled study was conducted in Beijing, China. Patients aged 30-75 years were eligible for enrolment if they had blood pressure [systolic (SBP) ≥ 140 mmHg and/or diastolic (DBP) ≥ 90 mmHg; or SBP ≥ 130 mmHg and/or DBP ≥ 80 mmHg with diabetes]. We recruited 190 patients randomized to either the HBPT or the UC groups for 12 weeks. The primary endpoints were blood pressure reduction and the proportion of patients achieving the target blood pressure.@*RESULTS@#Totally, 172 patients completed the study, the HBPT plus support group ( n = 84), and the UC group ( n = 88). Patients in the plus support group showed a greater reduction in mean ambulatory blood pressure than those in the UC group. The plus support group had a significantly higher proportion of patients who achieved the target blood pressure and maintained a dipper blood pressure pattern at the 12th week of follow-up. Additionally, the patients in the plus support group showed lower blood pressure variability and higher drug adherence than those in the UC group.@*CONCLUSION@#HBPT plus additional support results in greater blood pressure reduction, better blood pressure control, a higher proportion of dipper blood pressure patterns, lower blood pressure variability, and higher drug adherence than UC. The development of telemedicine may be the cornerstone of hypertension management in primary care.

Objective: To explore the risk intensity and related influencing factors of post-traumatic stress disorder (PTSD) among high-stress rescue workers, and to provide effective tools for the risk assessment of PTSD in military rescue workers. Method: From June to August 2022, cluster sampling was used to select the high-stress rescue personnel of an Army department as the survey subjects. The acute Stress reaction (ASD) scale and PTSD checklist were used to evaluate the risk of PTSD in military rescue personnel. Multivariate logistic regression were used to analyze the influencing factors of PTSD. Results: The age of 4 460 subjects was (24.38±4.072) years old, including 4 396 males (98.6%). The positive rate of initial screening for ASD was 2.85% (127/4 460). The positive rate of PTSD was 0.67% (30/4 460). Multivariate logistic regression model analysis showed that female, older age, recent trauma exposure history, passive smoking and alcohol consumption were at higher risk of ASD, the values of OR (95%CI) were 4.183 (1.819-9.618), 6.278 (1.363-28.912), 3.094 (1.500-6.379), 2.059 (1.298-3.267) and 2.607 (1.614-4.211), respectively; Lower education level was associated with lower risk of ASD, OR (95%CI) was 0.593 (0.359-0.978); People who are older, thinner, have a history of mental illness, and drink alcohol were at higher risk for PTSD, the values of OR (95%CI) were 20.144 (2.459-165.043), 10.287 (2.218-47.700), 91.104 (8.592-965.980) and 2.866 (1.144-7.180), respectively. Conclusion: Gender, age, education level, passive smoking, alcohol consumption, past history of mental illness and body mass index may be related to the potential risk of PTSD in rescue workers,passive smoking, alcohol consumption, and weight controlling should be focused on to reduce potential risks of PTSD.

OBJECTIVE@#This study aimed to reveal the insomnia burden and relevant influencing factors among informal caregivers (ICs) of hospitalized patients with lung cancer.@*METHODS@#A cross-sectional study on ICs of hospitalized patients with lung cancer was conducted from December 31, 2020 to December 31, 2021. ICs' burden was assessed using the Caregiver Reaction Assessment (CRA), Hospital Anxiety and Depression Scale (HADS), and Insomnia Severity Index (ISI). Linear and logistic regression models were used to identify the influencing factors.@*RESULTS@#Among 289 ICs of hospitalized patients with lung cancer, 83 (28.72%), 53 (18.34%), and 14 (4.84%) ICs experienced mild, moderate, and severe insomnia, respectively. The scores concerning self-esteem, lack of family support, financial problems, disturbed schedule, and health problems were 4.32 ± 0.53, 2.24 ± 0.79, 2.84 ± 1.14, 3.63 ± 0.77, and 2.44 ± 0.95, respectively. ICs with higher Activities of Daily Living Scale (ADLS) scores were associated with a lower risk of insomnia, with an odd ratio ( OR) and 95% confidence interval ( CI) of 0.940 (0.898-0.983). Among the ICs, female gender ( OR = 2.597), alcohol consumption ( OR = 3.745), underlying medical conditions ( OR = 11.765), long-term caregiving experience ( OR = 37.037), and higher monthly expenses ( OR = 5.714) were associated with a high risk of insomnia.@*CONCLUSION@#Of the hospitalized patients with lung cancer, 51.9% experienced insomnia. Patients' ADL, ICs gender, alcohol consumption, underlying medical conditions, caregiving duration, and monthly expenses were influencing factors. Therefore, prompt screening and early intervention for ICs of patients with lung cancer is necessary.

Objective@#To determine the factors influencing insomnia and construct early insomnia warning tools for rescuers to informbest practices for early screening and intervention.@*Methods@#Cluster sampling was used to conduct a cross-sectional survey of 1,133 rescuers from one unit in Beijing, China. Logistic regression modeling and R software were used to analyze insomnia-related factors and construct a PRISM model, respectively.@*Results@#The positive rate of insomnia among rescuers was 2.74%. Accounting for participants' age, education, systolic pressure, smoking, per capita family monthly income, psychological resilience, and cognitive emotion regulation, logistic regression analysis revealed that, compared with families with an average monthly income less than 3,000 yuan, the odds ratio ( ) values and the [95% confidence interval ( )] for participants of the following categories were as follows: average monthly family income greater than 5,000 yuan: 2.998 (1.307-6.879), smoking: 4.124 (1.954-8.706), and psychological resilience: 0.960 (0.933-0.988). The ROC curve area of the PRISM model (AUC) = 0.7650, specificity = 0.7169, and sensitivity = 0.7419.@*Conclusion@#Insomnia was related to the participants' per capita family monthly income, smoking habits, and psychological resilience on rescue workers. The PRISM model's good diagnostic value advises its use to screen rescuer early sleep quality. Further, advisable interventions to optimize sleep quality and battle effectiveness include psychological resilience training and smoking cessation.

<p><b>BACKGROUND</b>The optimal timing of surgical revascularization for patients presenting with ST-segment elevation myocardial infarction (STEMI) and impaired left ventricular function is not well established. This study aimed to examine the timing of surgical revascularization after STEMI in patients with ischemic heart disease and left ventricular dysfunction (LVD) by comparing early and late results.</p><p><b>METHODS</b>From January 2003 to December 2013, there were 2276 patients undergoing isolated coronary artery bypass grafting (CABG) in our institution. Two hundred and sixty-four (223 male, 41 females) patients with a history of STEMI and LVD were divided into early revascularization (ER, <3 weeks), mid-term revascularization (MR, 3 weeks to 3 months), and late revascularization (LR, >3 months) groups according to the time interval from STEMI to CABG. Mortality and complication rates were compared among the groups by Fisher's exact test. Cox regression analyses were performed to examine the effect of the time interval of surgery on long-term survival.</p><p><b>RESULTS</b>No significant differences in 30-day mortality, long-term survival, freedom from all-cause death, and rehospitalization for heart failure existed among the groups (P > 0.05). More patients in the ER group (12.90%) had low cardiac output syndrome than those in the MR (2.89%) and LR (3.05%) groups (P = 0.035). The mean follow-up times were 46.72 ± 30.65, 48.70 ± 32.74, and 43.75 ± 32.43 months, respectively (P = 0.716). Cox regression analyses showed a severe preoperative condition (odds ratio = 7.13, 95% confidence interval 2.05-24.74, P = 0.002) rather than the time interval of CABG (P > 0.05) after myocardial infarction was a risk factor of long-term survival.</p><p><b>CONCLUSIONS</b>Surgical revascularization for patients with STEMI and LVD can be performed at different times after STEMI with comparable operative mortality and long-term survival. However, ER (<3 weeks) has a higher incidence of postoperative low cardiac output syndrome. A severe preoperative condition rather than the time interval of CABG after STEMI is a risk factor of long-term survival.</p>

<p><b>OBJECTIVE</b>To evaluate the efficacy of intraoperative magnetic resonance imaging (iMRI) and multimodal navigation in surgical resection of glioblastoma.</p><p><b>METHODS</b>Between February 2009 and July 2010, 76 glioblastoma patients underwent surgical resection guided by iMRI and multimodal navigation. The cohort consisted of 43 male and 33 female patients, with a mean age of 49 years (range: 14-79 years). Rates of gross total resection (GTR) and extent of resection (EoR) were calculated at first and final iMRI scans.Pearson χ(2) test was used to compare the rates of GTR.</p><p><b>RESULTS</b>iMRI and multimodal navigation were successfully implemented in all cases. Rates of GTR were misestimated by neurosurgeons in 24 cases (31.6%), which were confirmed by first iMRI. Total tumor resection were achieved in 20 cases (26.3%) as a result of iMRI scan, increasing the rates of gross total resection from 52.6% to 78.9% (χ(2) = 11.692, P = 0.001). Extent of resection in 28 patients who underwent further tumor resection were increased from 81.5% to 98.1%, leading to the overall extent of resection improved from 92.3% to 98.4%. At 3-month follow-up, 3 cases (3.9%) developed permanent neurologic deficits. The mean clinical follow-up was 15.6 months (range 3.0-45.0 months). The 2-year overall survival rate was 19.7%. The median progression-free survival of gross total resection group was 12 months (95% CI: 10.1-13.9 months), compared with 9 months (95%CI: 7.9-10.1 months) of the subtotal resection group (χ(2) = 4.756, P = 0.029). The overall survival of gross total resection group was 16 months (95% CI: 13.7-18.3 months), compared with 12 months (95% CI: 9.7-14.3 months) of the subtotal resection group (χ(2) = 7.885, P = 0.005).</p><p><b>CONCLUSION</b>Combined with multimodal navigation, iMRI helps maximize surgical resection of glioblastoma, preserving neurological function while increasing progression-free survival and overall survival.</p>

To study the intervention programs on smoking cessation in a general hospital and to evaluate its effects of the programs. Four methods including: a) the intervention through specialists in the smoking cessation clinic, b) short-time intervention in the out-patient department,c) free medical intervention, d) group intervention, were adopted for different smokers, with health counseling, psychological intervention and drug treatment. Intervention effect was evaluated by standard methods. During the 20-month period of the project, we treated 690 cases and 402 completed 6-month follow-up. Preliminary results in 402 cases showed that the three methods of smoking cessation interventions could reduce the amount of cigarette smoking and increase the quitting rate. Motivation to quit smoking, intervention methods and intensity of intervention seemed cessation clinic (31.6%) and in the group intervention (30.9%) was higher than short-time intervention in free medical events (15.1%). The successful rate of smoking cessation depended on the motivation of quitters, and the attitude, methods and intervention skills of the physicians.Therefore, it is necessary to explore and develop smoking cessation service models suitable to national context and individual intervention methods in China.
