ObjectiveImprovement in the quality of life is reflected in the narrowing of the gap between health-adjusted life expectancy (HALE) and life expectancy (LE). The effect of megacity expansion on narrowing the gap is rarely reported. This study aimed to disclose this potential relationship.MethodsAnnual life tables were constructed from identified death records and population counts from multiple administrative sources in Guangzhou, China, from 2010 to 2020. Joinpoint regression was used to evaluate the temporal trend. Generalized principal component analysis and multilevel models were applied to examine the county-level association between the gap and social determinants.ResultsAlthough LE and HALE in megacities are increasing steadily, their gap is widening. Socio-economic and health services are guaranteed to narrow this gap. Increasing personal wealth, a growing number of newborns and healthy immigrants, high urbanization, and healthy aging have helped in narrowing this gap.ConclusionIn megacities, parallel LE and HALE growth should be highly considered to narrow their gap. Multiple social determinants need to be integrated as a whole to formulate public health plans. 相似文献

Objective This study aimed to assess the association of waist circumference(WC) with all-cause mortality among Chinese adults.Methods The baseline data were from Shanxi Province of 2002 China Nutrition and Health Survey. The death investigation and follow-up visit were conducted from December 2015 to March 2016. The visits covered up to 5,360 of 7,007 participants, representing a response rate of 76.5%. The Cox regression model and floating absolute risk were used to estimate hazard ratio and 95% floating CI of death by gender and age groups(≥ 60 and 60 years old). Sensitivity analysis was performed by excluding current smokers; participants with stroke, hypertension, and diabetes; participants who accidentally died; and participants who died during the first 2 years of follow-up.Results This study followed 67,129 person-years for 12.5 years on average, including 615 deaths. The mortality density was 916 per 100,000 person-years. Low WC was associated with all-cause mortality among men. Multifactor-adjusted hazard ratios(HR) were 1.60(1.35–1.90) for WC 75.0 cm and 1.40(1.11–1.76) for WC ranging from 75.0 cm to 79.9 cm. Low WC( 70.0 cm and 70.0–74.9 cm) and high WC(≥ 95.0 cm) groups had a high risk of mortality among women. The adjusted HRs of death were 1.43(1.11–1.83), 1.39(1.05–1.84), and 1.91(1.13–3.22).Conclusion WC was an important predictor of death independent of body mass index(BMI). WC should be used as a simple rapid screening and predictive indicator of the risk of death. 相似文献

BackgroundMany Eastern reports attempted to identify predictive variables for esophago-jejunal anastomosis leakage (EJAL) after total gastrectomy for cancer. There are no definitive answers about reliable risk factors for EJAL. This retrospective study shows the largest Western series focused on this topic.MethodsThis is a multicenter retrospective study analyzing patients’ datasets collected by 18 Italian referral Centres of the Italian Research Group for Gastric Cancer (GIRCG) from 2000 to 2018. The inclusion criteria were pathological diagnosis of gastric and esophageal (Siewert III) carcinoma requiring total gastrectomy. The primary end point of risk analysis was the occurrence of EJAL; secondary end points were post-operative (30-day) morbidity and mortality, length of stay (LoS), and survival.ResultsData of 1750 patients submitted to total gastrectomy were collected. EJAL developed in 116 (6.6%) patients and represented the 26.3% of all the 441 observed post-operative surgical complications. EJAL diagnosis was followed by a reoperation in 39 (33.6%) patients and by an endoscopic/radiological procedure in 30 cases (25.9%). In 47 patients (40.5%) EJAL was managed with conservative approach. Post-operative LoS and mortality were significantly higher after EJAL occurrence (27 days versus 12 days and 8.6% versus 1.6%, respectively). At risk analysis, comorbidities (particularly, if respiratory), minimally invasive surgery, extended lymphadenectomy, and anastomotic technique resulted significant predictive factors for EJAL. EJAL did not significantly affect survival.ConclusionsThese results were consistent with Asian experiences: the frequency of EJAL and its higher rate observed in patients with comorbidities or after minimally invasive approach were confirmed. 相似文献

ObjectivesSarcopenia and metabolic syndrome (MetS) are associated with the prognosis from malignant tumors. However, evidence of the relationship between sarcopenia and MetS among gastric cancer (GC) patients following radical gastrectomy is lacking. This study assessed the association between preoperative sarcopenia and MetS among GC patients and analyzed the prognosis of patients with different malnutrition statuses.MethodsWe prospectively assessed the preoperative statuses of sarcopenia and MetS among patients who underwent radical gastrectomy from July 2014 to December 2017. We combined sarcopenia and MetS to generate four groups: MetS-related sarcopenia group (MSS), sarcopenia group (S), MetS group (MS), and normal group (N).ResultsA total of 749 patients with resectable GC were included in this study. Preoperative MetS was associated with sarcopenia (p < 0.001). Multivariate logistic regression presented that MetS-related sarcopenia (OR = 2.445; p = 0.010) and sarcopenia alone (OR = 2.117; p = 0.001) were independent predictors of grade Ⅱ and above complications, while MetS alone was not (p = 0.342). Cox regression analysis revealed that MetS-related sarcopenia led to the worst prognosis in the four groups (MSS vs MS: HR = 3.555, p < 0.001; MSS vs N: HR = 2.020, p = 0.003; MSS vs S: HR = 1.763, p = 0.021). However, the MetS group had better prognosis than the normal group (MS vs N: HR = 0.568, p = 0.048).ConclusionPreoperative MetS was associated with sarcopenia among GC patients. MetS-related sarcopenia resulted in a significantly worse prognosis. The long-term prognoses of patients with sarcopenia were impaired by preoperative MetS, while patients without sarcopenia benefited. Thus, patients with both sarcopenia and MetS require more medical interventions. 相似文献

Stroke is a major cause of morbidity and mortality, and activation of the immune system can impact on stroke outcome. Although the majority of research has focused on the role of the immune system after stroke there is increasing evidence to suggest that inflammation and immune activation prior to brain injury can influence stroke risk and outcome. With the high prevalence of co-morbidities in the Western world such as obesity, hypertension and diabetes, pre-existing chronic ‘low-grade’ systemic inflammation has become a customary characteristic of stroke pathophysiology that needs to be considered in the search for new therapies. The importance of the immune system in stroke has been demonstrated in a number of ways, both experimentally and in the clinical setting. This review will focus on the effect of immune activation arising from systemic inflammatory conditions and infection, how it affects the incidence and outcomes of stroke, and the possible underlying mechanisms involved.
