RESUMO
Objective To explore the relationship between baseline urinary protein levels and the onset of chronic obstructive pulmonary disease (COPD). Methods A questionnaire survey, blood and urine sample collection, physical examination, and pulmonary function test were conducted among permanent residents over 40 years old in Pudong New Area, Shanghai. The subjects were divided into four groups based on the baseline urine albumin-to-creatinine ratio (ACR) quartiles (0~1.65 mg/g, 1.65~4.89 mg/g, 4.89~10.78 mg/g, and ≥10.78 mg/g). Cox regression analysis was used to explore the relationship between ACR levels and the incidence of COPD in middle-aged and elderly people. Results Among the 3 105 subjects, the median follow-up time was 3.212 years (P25~P75:3.102~3.473). 116 new cases of COPD were observed, with an incidence density of 10.423 per 1000 person-years. The incidence densities for COPD at four ACR levels were 7.922 per 1 000 person-years, 8.300 per 1 000 person-years , 11.419 per 1 000 person-years, and 13.843 per 1 000 person-years, respectively. Cox regression analysis revealed that as the ACR level increased, there was a rising trend in the incidence rate of COPD (χ2=4.396, P=0.036). After adjusting for gender, age, education level, occupational exposure to dust, history of childhood pneumonia, smoking, family history of COPD, central obesity, and hypertension, the risk of developing COPD was 2.499 times higher (95% CI: 1.460~4.276) for ACR levels ≥10.78 mg/g compared to the reference group with a baseline ACR level of 0~1.65 mg/g. Conclusion Elevated ACR levels in middle-aged and elderly population may increase the risk of COPD, and early monitoring of urine protein levels is beneficial for COPD prevention.
RESUMO
ObjectiveTo evaluate the intervention effect of meteorological risk forecasting service on acute onset and medical expenses of chronic obstructive pulmonary disease(COPD) patients, and to provide scientific basis for the establishment of health management model for chronic obstructive pulmonary disease(COPD) patients. MethodsStudy subjects were recruited from chronic obstructive pulmonary patients aged ≥40 in Pudong New Area. Propensity score matching method was used to determine the intervention group and the control group. The control group received regular health education and follow-up management, and the intervention group was provided with meteorological and environmental risk forecasting services through WeChat, mobile phone short message service(SMS)and telephone. Finally, a total of2 589 subjects were included in the analysis, including 1 300 in the intervention group and 1 289 in the control group. General demographic data, past medical history and family history of COPD, COPD related knowledge and practice survey, COPD related symptom assessment, acute onset, health service utilization and medical expenses before and after intervention were collected through questionnaire survey. The differences of acute attack, health service utilization and related medical expenses between the two groups before and after intervention were compared to evaluate the intervention effect. ResultsIn terms of acute attacks, after intervention, the incidence of acute attacks in the intervention group was lower than that before intervention(χ2=52.901, P<0.001), and the incidence of acute attacks in the groups with different intervention methods was lower than that before intervention (P<0.001). WeChat had the best effect, decreasing the incidence by 14.4%, followed by mobile phone SMS SMS decreasing by 12.3%. In terms of utilization of health services, the outpatient rate due to acute attack was lower in the intervention group after intervention than that before intervention (χ2=7.129, P=0.008), and the outpatient rate due to acute attack was lower in the subjects who received the forecast service through mobile phone SMS than that before intervention (χ2=4.675, P<0.001). In terms of medical expenses, there was no significant difference between control group and intervention group with different intervention methods before intervention (P>0.05). After intervention, the difference between the control group and the intervention group with different intervention methods was statistically significant (H=11.864, P<0.05). The results of multiple comparisons showed that compared with the control group, the average annual medical expenses of patients receiving mobile phone SMS and telephone forecasting services after intervention were lower than those of the control group, and the difference was statistically significant (P<0.05). ConclusionMeteorological risk forecasting service can reduce the acute onset of COPD, reduce the rate of consultation and medical expenses due to acute onset, and provide scientific basis for the basic COPD health management model.
RESUMO
Objective:To analysis the clinical features of patients with acute myocardial infarction (AMI) presenting de Winter pattern on electrocardiogram.Methods:A total of 1 287 patients with AMI admitted to Beijing Luhe Hospital between June 2017 and January 2019 were enrolled in the study. Electrocardiogram and clinical features of 13 patients with AMI presenting de Winter pattern on electrocardiogram were analyzed and compared with anterior wall ST-segment elevation myocardial infarction(STEMI, n=206). Results:Among the 13 patients, 12 were males, aged (52.23±12.55) years old. Compared to patients with anterior wall STEMI, the age in the de Winter group was younger [(52.23±12.55)years vs. (59.79±12.46)years; t=-2.12, P=0.03], and the time from onset to appearing a typical ECG was shorter [109.0 (71.5, 152.0)min vs. 200.5 (120.0, 397.5)min; Z=-3.38, P<0.01]. Three cases showed a shifting between de Winter pattern and typical STEMI ECG: the de Winter ECG pattern progressed to STEMI in 2 cases, 1 case changed from STEMI to de Winter,then converted to STEMI again. The emergency angiography was performed in all 13 patients, angiography showed that proximal left anterior descending branch (LAD) was involved in 11 cases, mid LAD was involved in 1 case, and diffuse spasm occurred in all vessels in 1 case. The de Winter ECG pattern vanished in all patients after primary percutaneous coronary intervention or emergency angiography. Conclusions:The de Winter ECG pattern suggests an acute proximal or mid LAD artery occlusion, and the de Winter ECG pattern can be alternated with STEMI. The de Winter pattern should be recognized and revascularization should be given early.
RESUMO
Objective@#To describe the 40-years trend for the mortality of colorectal cancer (CRC) in Shanghai and to estimate the effect of age, period, and birth cohort with Age-Period-Cohort (APC) model.@*Methods@#Data on tumor-releated death from 1975 Janurary 1 to 2014 December 31 was derived from the Yangpu District of Shanghai Center for Diseases Prevention and Control tumor registration system. Colonrectal cancer cases (C18.2-C18.9 and C20 in ICD10) were selected for analyses. Crude mortality, age-adjusted mortality, and Average Annual Percent Changes (AAPCs) were calculated for colon cancer and rectal cancer. The difference of AAPCs between male/female and different age groups were tested. An APC model (reference cohort and period were 1900 and 1975, respectively) was constructed to estimate the age-effect, period-effect, and cohort-effect on the colorectal cancer death.@*Results@#During 1975-2014, 6 725 cases died of colorectal cancer (the cased of colon and rectal cancer were 3 684 and 3 041, respectively). The crude mortality and age-adjusted mortality of colon cancer was 8.83/100 000 and 6.76/100 000, respectively. The crude mortality and age-adjusted mortality of rectal cancer were 7.32/100 000 and 5.67/100 000, respectively. For population in Yangpu District, the crude mortality and age-adjusted mortality of colon cancer increased with time, and the crude mortality of rectal cancer increased with time (P<0.001). AAPC of the crude mortality rate (5.6%) and age-adjusted mortality rate (2.3%) of colon cancer were higher than those in rectal cancer (3.0% and -0.3%), respectively (both P values <0.001). AAPC of the crude mortality rate (males vs. females was 6.2% vs. 5.0%, P<0.05) and age-adjusted mortality rate (males vs. females was 2.7% vs. 1.7%, P<0.05) of colon cancer were higher in males than in females. APC model indicted that CRC-related death increased with age. During 1901 to 1941, the RR values of cohort effects for colon and rectal cancer death were 1.09-5.57 and from 1.04-2.28, respectively; During 1946 to 1991, the RR values of cohort effects for colon cancer and rectal cancer were 5.51-4.32 and 2.16-0.89.@*Conclusion@#From 1975 to 2014, the mortality of CRC in Yangpu District increased gradually, and colon cancer mortality in males increased faster than that in females. The risk of death from colorectal cancer in the 1946-1991 birth cohort declined.
