Whether airport groups develop synergistically has become a concern for the aviation industry. Existing studies have neglected the dynamic comprehensive evaluation and analysis of influencing factors of synergy degree. Taking the synergistic development of airport groups as the research perspective, we integrate the dynamic comprehensive evaluation model into the traditional synergy model. From two dimensions of airport development and regional economy, we measured the static synergy degree of the Chengdu-Chongqing airport group and the dynamic synergetic development degree on the overall time series. Further, using a spatial econometric model, we construct a distance economy-nested spatial weight matrix so as to explore the influence of each indicator on the synergy degree of the composite system. The results show that the overall synergy of the Chengdu-Chongqing airport group is above 0.5 in terms of static synergy degree. The clustering spectrum shows that the Chengdu-Chongqing airport group can be divided into three categories and basically forms the characteristic of “two main and multiple auxiliary airports.” In terms of dynamic synergetic development degree and comprehensive evaluation value, the change speed of synergy degree is relatively smooth in the early stage and fluctuates in the later stage, and the overall dynamic evaluation value of the Chongqing regional airports is high. The effects of the explanatory variables of the airport group composite system on the synergy degree show more direct effects than spillover effects, and the direct effects are all positive feedback effects, while the negative spillover effects of the explanatory variables cannot be ignored.

Smoking is the most important modifiable risk factor for bladder cancer (BC), with the odds of developing BC among current and former smokers 3 times higher than never-smokers. We hypothesized that the observed disparities in BC incidence may be partially attributable to differences in smoking prevalence. We examined the attributable risk of BC related to smoking according to race/ethnicity and sex.We used data from SEER and the Behavioral Risk Factor Surveillance System to estimate BC cases that would have been prevented if current and former smokers had never smoked to calculate the Population Attributable Fractions, stratified by sex and race/ethnicity. SDs of BC incidences across racial/ethnic groups before and after smoking elimination were calculated to estimate disparities.A total of 25,747 cases of BC were analyzed from 21 registries in 2018. By removing smoking, 10,176 cases (40%) would have been eliminated. Smoking was associated with a higher proportion of BC cases among males (42%) than females (36%). Across racial/ethnic groups, smoking contributed to the highest proportion of BC cases among American Indian/Alaska Natives (AI/AN) (43%) and Whites (36%) for females, and highest among AI/ANs (47%) and Blacks (44%) for males. Removing smoking, the SD of BC incidence across racial/ethnic groups was reduced for females (39%) and males (44%).Approximately 40% of cases of BC in the United States are attributable to smoking, with the highest proportion in AI/ANs for both males and females, and the lowest in Hispanics for females and Asians and Pacific Islanders for males. Smoking contributes to almost half of racial/ethnic disparities in BC incidence in the United States. Accordingly, health policy to encourage smoking cessation among racial-ethnic minorities may substantially reduce inequalities in BC incidence.

Background Study has shown that sarcopenia increases the risk of poor outcomes in patients with hypertension. Inflammation is one of the important reasons for the occurrence and development of sarcopenia. Regulating systemic inflammation may be a potential intervention for sarcopenia in hypertensive patients. Diet is one of the important measures to improve systemic inflammation. The dietary inflammatory index (DII) is a tool designed to assess the inflammatory potential of the diet, the association between DII and sarcopenia in hypertensive patients is unclear. Objective To explore the relationship between the DII and sarcopenia in patients with hypertension. Method Data from the National Health and Nutrition Examination Survey (NHANES) 1999–2006 and 2011–2018. A total of 7,829 participants were evaluated. Participants were divided into four groups based on the quartile of the DII: Q1 group (n = 1,958), Q2 group (n = 1,956), Q3 group (n = 1,958) and Q4 group (n = 1,957). The relationship between the DII and sarcopenia was assessed by logistic regression analysis based on the NHANES recommended weights. Result The DII was significantly associated with sarcopenia in patients with hypertension. After full adjustment, patients with higher DII (OR: 1.22, 95% CI: 1.13–1.32, p < 0.001) have a higher risk of sarcopenia. Compared with Q1 group, the group with higher DII levels had a higher risk of sarcopenia (Q2: OR: 1.23, 95%CI: 0.89–1.72, p = 0.209; Q3: OR: 1.68, 95%CI: 1.20–2.35, p = 0.003; Q4: OR: 2.43, 95%CI: 1.74–3.39, p < 0.001). Conclusion High DII is associated with an increased risk of sarcopenia in hypertensive patients. The higher the level of DII, the higher the risk of sarcopenia in hypertensive patients.
