ABSTRACT
Objective:To explore the changes and influencing factors of psychological distress in patients with primary acute myocardial infarction (AMI) in different periods, and to provide reference for the management of psychological distress in patients with primary AMI.Methods:This was a longitudinal, prospective, observational study. From June 2021 to September 2022, 118 patients with primary AMI in Peking Union Medical College Hospital and Peking University First Hospital were selected as the research objects. The psychological distress level of patients was investigated on the points of 24 hours after illness (T 1), before discharge (T 2), 1 month after discharge (T 3), 3 months after discharge (T 4), 6 months after discharge (T 5) and 12 months after discharge (T 6), and the influencing factors were analyzed. Results:The detection rate of psychological distress in 6 follow-up survey nodes was 66.95% (79/118), 48.31% (57/118), 29.66% (35/118), 24.58% (29/118), 19.49% (23/118) and 15.25% (18/118) respectively. Education level, family per capita income and disease awareness had significant effects on the psychological distress of patients with primary AMI at the time points from T 1 to T 6 ( β values were - 1.262 to - 0.212, all P<0.05). Conclusions:The level of psychological distress in primary AMI patients decreased with time. Nursing staff should pay attention to the trajectory and influencing factors of psychological pain, and formulate targeted intervention measures to reduce the level of psychological pain and promote the comprehensive rehabilitation of patients.
ABSTRACT
Objective@#To investigate the clinical features of anti-signal recognition particle (SRP) antibody-positive patients with dermatomyositis/clinically amyopathic dermatomyositis (DM/CADM) .@*Methods@#Clinical data were collected from 90 patients with DM/CADM, who were hospitalized at the Department of Dermatology, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from June 2015 to July 2017. Immunoblotting assay was performed to determine the serum level of anti-SRP antibody in these patients. Statistical analysis was carried out using t test and Chi-square test.@*Results@#Of the 90 patients with DM/CADM, 11 (12.2%) were positive for serum anti-SRP antibody, including 6 with DM and 5 with CADM. Among 82 adult patients with DM/CADM, the prevalence of malignant tumors was significantly higher in the patients with anti-SRP antibody than in those without (7/9 vs. 31.5%[23/73], χ2 = 7.394, P = 0.006) . The 11 patients with anti-SRP antibody had typical DM skin lesions, and their cutaneous dermatomyositis disease area and severity index (CDASI) was 18.1 ± 2.9. The prevalence of "angel wings sign" (aliform erythema on the trunk) was significantly higher in the patients with anti-SRP antibody than in those without (7/11 vs. 29.9%[20/67], Fisher′s exact test, P = 0.028) . The positive rate of antinuclear antibody was significantly higher in the patients with anti-SRP antibody than in those without (4/8 vs. 16.7%[13/78], χ2 = 6.053, P = 0.014) . Magnetic resonance imaging of muscles of both thighs of the 10 patients with anti-SRP antibody (6 with DM and 4 with CADM) showed the presence of abnormal signals in the thigh muscle group in 8, swelling of the muscle group in 2, subcutaneous edema in 2, myofascial swelling in 1, and no abnormities in 2. No interstitial lung disease or myocardial involvement was observed in the patients with anti-SRP antibody.@*Conclusions@#The anti-SRP antibody-positive patients with DM/CADM showed a high prevalence of "angel wings sign" , and a high risk of malignant tumors. Early detection of the anti-SRP antibody in patients with DM/CADM is helpful to predict the occurrence of malignant tumors.
ABSTRACT
Objective To investigate the effects of two different arm postures on radial artery puncture. Methods We randomly divided 100 patients into control group and experiment group according to the operation sequence, 50 patients in each group. In the control group, the traditional method was used for radial artery puncture and sheath placement, while in the experiment group the modified method was used. Result Compared with the control group, the success rate of radial artery puncture in the experiment group was significantly higher (P<0.05), and the time needed was significantly shorter (P<0.05). Conclusions The modified arm posture for radial artery puncture and sheath placement is more effective for exposure of the radial artery puncture point and ensure the stability of the puncture site. With this method, we can improve the success rate of radial artery puncture and shorten the puncture time. It is worthy of clinical application.
