RESUMO
Objective To evaluate the mediating effect of lifestyles on the association between family history and cardiovascular disease (CVD). Methods This study was based on the "Early Screening and Comprehensive Intervention of High-risk Populations of Cardiovascular Disease Project". The data were collected from 6 project sites in Hubei Province. Logistic regression analysis was used to investigate the impact of family history and lifestyle on CVD, and the relationship between family history and lifestyle. Mediation analysis was used to evaluate the mediating effect of lifestyle on the association between family history and CVD. Results A total of 5 871 subjects were included in the study from 2015 to 2016, of whom 500 (8.52%) developed CVD and 484 had family history of CVD. The risk of developing CVD was significantly increased in participants with family history of disease (OR = 1.458, P = 0.014) and in those with high level of physical activity (OR = 1.081, P = 0.026). The increase of leisure physical activity time showed a protective effect on developing CVD (OR = 0.977, P < 0.001). Participants with family history significantly increased leisure physical activity (OR = 2.085, P < 0.001), and were less likely to choose occupations with high levels of physical activity (OR = 0.524, P < 0.001). The results of mediation analysis showed that leisure physical activity and occupational physical activity mediated the relationship between family history and CVD, and the β value of the mediating effects were -0.004 (P = 0.010) and 0.002 (P = 0.045), respectively. The β value of the direct effect of family history on CVD was 0.033 (P < 0.05). Conclusion Leisure physical activity and occupational physical activity might mediate the relationship between family history and CVD. People with family history would reduce the risk of developing CVD by increasing leisure physical activity time and choosing occupations with low levels of physical activity.
RESUMO
Objective To analyze the equity of the allocation of oral medical resources and the accessibility of health service capabilities in Wuhan. Methods The equity of oral medical resources was calculated with Gini coefficient and Theil index, accessibility was assessed by two-step floating catchment area model, and the spatial autocorrelation was used to study the high-low clustering of accessibility. Results The Gini coefficient of oral medical resources based on population level was around 0.3, and the Gini coefficient of oral medical resources based on geographic area was greater than 0.6. Theil index calculation results were similar. In terms of overall accessibility, the area with poor accessibility was 2,428 square kilometers, reaching 28.38% of the total area, while the area with better accessibility accounted for 14.18%. Conclusion The allocation of oral medical care resources based on population distribution was fairer and better than that based on geographic area. Moreover, the geographical accessibility varies greatly between regions, showing the characteristics of high-high cluster and low-low cluster.
RESUMO
Objective:To study the efficacy and safety of early abdominal puncture drainage (APD) in severe acute pancreatitis (SAP).Methods:A retrospective study was conducted on 189 patients with SAP who were managed at the Department of Intensive Medicine of the Second Affiliated Hospital of Anhui Medical University from January 2013 to May 2020. According to whether ultrasound-guided APD was performed within one week after admission to ICU, these patients were divided into 2 groups: patients treated with APD (the APD group) and patients treated without APD (the non-APD group). Clinical data, including the acute physiological and chronic health status (APACHE) Ⅱ score, modified Marshall score, sequential organ failure evaluation (SOFA) score, and prognostic indicators including the retroperitoneal percutaneous drainage (PCD) rate and length of hospital stay, were compared between the two groups before and 1 week after surgery.Results:Of the 189 SAP patients in this study, there were 110 males and 79 females, aged (52.5±17.4) years old. On admission to ICU, the blood amylase, C-reactive protein, procalcalonin, interleukin-6, APACHE II score, modified Marshall score and SOFA score in the APD group were significantly higher than those in the non-APD group. After 1 week of treatment, most clinical indicators in the 2 groups were significantly improved, and there were no significant differences between these indicators (all P>0.05). There were no significant differences in the abdominal infection, retroperitoneal PCD and mortality rates between the APD group and the non-APD group ( P>0.05). The length of hospital stay [29 (18, 45) vs 21 (15, 32) d] and ICU stay [5 (3, 11) vs. 7 (5, 17) d] in the APD group were significantly higher than those in the non-APD group ( P<0.05). Conclusion:For patients with SAP with peritoneal effusion, early APD effectively improved the condition and prognosis without increasing the peritoneal infection and mortality rates.
