RESUMO
Objective:To examine the association between baseline serum albumin level and short-term, long-term outcomes in patients with systemic sclerosis associated interstitial lung disease (SSc-ILD).Methods:A total of 259 patients with SSc-ILD who were hospitalized in West China Hospital of Sichuan University from January 2008 to December 2018 were enrolled. The data of serum albumin, demographic characteristics, peripheral blood hemoglobin at admission, and treatment plan were obtained from the hospital information management system, and the survival of the patients were followed up to June 1, 2019. The mean baseline serum albumin of 259 patients was 37.67 g/L, there were 118 patients with serum albumin ≤37.67 g/L (low protein group) and 141 patients with serum albumin>37.67 g/L (high protein group).Results:There were 64 males and 195 females with a mean age of 50.0(41.0, 61.0) years. The follow-up time was 627(61, 1 426) days. Compared to high protein group, the low protein group had higher proportion of male patients [30.5%(36/118) and 19.9%(28/141),χ 2=3.92, P=0.048], and higher levels of the erythrocyte sedimentation rate [45.0(27.0,69.0) vs. 29.0 (19.0,46.0)mm/1 h,χ 2=4.07, P<0.001], neutrophil percentage [71.50(63.35,77.13) vs. 65.60(59.50,72.50)%,χ 2=3.65, P<0.001], platelet [196(140,273) vs. 172(126,240)×10 9/L,χ 2=1.99, P=0.046], nutrophil/lymphocyte ratio [33.85(2.53,5.28) vs. 2.61(1.97,3.83),χ 2=4.57, P<0.001], platelet/lymphocyte ratio [149.0(112.0,216.8) vs. 113.5(72.76,158.8),χ 2=4.98, P<0.001], aspartate aminotransferase [27.0(21.0,39.0) vs. 23.0 (19.5,30.0) IU/L,χ 2=2.93, P=0.003], globulin [31.20(26.90,36.83) vs. 29.50(25.65,32.80) g/L,χ 2=2.28, P=0.023], serum cystatin C[1.14(0.98,1.33) vs. 1.02(0.88,1.16) mg/L,χ 2=3.80, P<0.001], IgA[2 710 (1 965,3 505) vs. 2 460 (1 862,3 105) mg/L,χ 2=2.13, P=0.033], IgG[15.05(12.83,21.08) vs. 13.60(11.53,17.23)g/L,χ 2=3.24, P=0.001], IgE[60.44(24.92,197.99) vs. 34.82(14.72,85.04) kIU/L,χ 2=3.33, P=0.001] and circulating immune complex [0.13(0.08,0.19) vs. 0.10(0.08,0.13)O.D,χ 2=2.60, P=0.009]; and lower levels of hemoglobin [121.5(101.8,132.0) vs. 129.0(119.0,142.0) g/L,χ 2=5.05, P<0.001], albumin [(33.28±3.49) vs.(41.34±2.95) g/L,χ 2=20.17, P<0.001] and IgM[1 320 (932,1 745) vs.1 560(1 170,2 030) mg/L, χ 2=2.63, P=0.009]. The utilization rate of antibiotics was higher in the low protein group (60 vs. 43 cases, χ 2=11.10, P=0.001). The number of patients followed up to 1, 5, and 10 years were 248, 245, and 244, respectively. The 1-year, 5-year, and 10-year cumulative survival rates of patients in low protein group and high protein group were(91.0% vs. 98.4%, χ 2=6.23, P=0.013;87.0% vs. 97.1%, χ 2=6.15, P=0.013; 81.6% vs. 97.1%, χ 2=7.00, P=0.008) respectively. Conclusions:Patients with scleroderma-associated interstitial lung disease have an increased risk of poorer prognosis when serum albumin ≤37.67 g/L.
RESUMO
Objective:To survey the knowledge, attitudes, and practice about chronic obstructive pulmonary disease (COPD) among general practitioners in Sichuan province.Methods:From October to November 2020, a questionnaire survey on knowledge, attitudes and practice (KAP) among 104 general practitioners who participated in the training of the comprehensive prevention and control of COPD organized by Sichuan Provincial Health Commission. The content of the questionnaire included the basic information and the KAP status of COPD. The descriptive analysis, Mann-Whitney U test, and Kruskal-Wallis H were used for statistical analysis. Results:A total of 104 questionnaires were distributed and 102 were returned with a response rate of 98.1%. General practitioners with different ages, professional titles, visits of COPD patients each month, and whether or not to refer COPD patients to higher-level hospitals were not significantly different in the scores of knowledge( U=1 276.00, H=0.78, U=1 074.00, U=589.00), attitude( U=1 141.50, H=1.75, U=1 090.00, U=585.00), and practice( U=1 221.00, H=0.31, U=1 163.00, U=499.50) (all P>0.05). In knowledge part the highest correctness rate was "quitting smoking is the most powerful interventions affecting the natural disease course of COPD" (100.0%, 102/102); the lowest was that"the main objective examination for judging the airflow limitation of COPD patients is the lung function test"(5.9%, 6/102). In the part of the attitude, the highest positive rate was "educating patients to quit smoking and avoid exposure to second-hand smoke" (65.7%,67/102); the lowest positive rate was "provide exercise guidance to patients "(43.1%, 44/102) and " be responsible for long-term treatment follow-up" (43.1%, 44/102). In the part of practice, the highest behavioral rate was "when receiving patients with COPD, actively pay attention to the treatment of comorbid diseases" (95.1%, 97/102); the lowest behavioral rate was "when patients with COPD were seen at the clinic, and the patients were advised of the best time to use the inhaler" (65.7%, 67/102). Conclusions:The study indicates that the relevant departments need to increase the intensity of knowledge training for general practitioners in Sichuan province. General practitioners should continuously improve their education, prevention, and treatment ability and implement the primary responsibilities for COPD management.
