ABSTRACT

We studied male centenarian Veterans using VA health care to understand the impact of social characteristics on their annual mortality rate, adjusting for prevalent health conditions. This longitudinal study used VA Electronic Health Record data from 1997 to 2012 (n = 1,858). Covariates included age, race, marital status, and periods of military service. The mean age was 100.4 ± 1.4 years, 76% were white, and 49% were married. The average annual mortality rate was 32 per 100 person-years. The annual mortality rate was stable and not affected by race but did vary by marital status. Divorced or separated centenarians had a 21% higher rate of death than married centenarians. A diagnosis of dementia or of congestive heart failure each increased the mortality risk by 37%. Providers should consider prevalent health conditions, as well as marital status, in managing care of centenarian Veterans.

ABSTRACT

BACKGROUND: Saphenous vein grafts (SVGs) remain the most often used conduits for coronary bypass grafting (CABG). Progressive intimal hyperplasia contributes to vein-graft disease and vein-graft failure (VGF). We compared the impact of intraoperative preservation of SVGs in a storage solution (DuraGraft®) versus heparinized saline on VGF-related outcomes after CABG. METHODS: From 1996 to 2004, 2436 patients underwent isolated CABG with ≥ 1 SVG. SVGs were consecutively treated with DuraGraft in 1036 patients (2001-2004) and heparinized saline in 1400 patients (1996-1999). Short- (< 30 days) and long-term (≥ 1000 days) outcomes were assessed using repeat revascularization (primary end point), and major adverse cardiac events (MACE) consisting of the composite of death, nonfatal myocardial infarction, or repeat revascularization. RESULTS: Mean follow-up in the DuraGraft group was 8.5 ± 4.2 years and 9.9 ± 5.6 years in controls. Short-term event rates were low and generally did not differ between groups. DuraGraft was associated with a 45% lower occurrence of nonfatal myocardial infarction after 1000 days (hazard ratio 0.55, 95% CI 0.41-0.74; P < 0.0001). There was 35% and 19% lower long-term risk for revascularization (HR 0.65, 95% CI 0.44-0.97; P = 0.037) and MACE (HR 0.81, 95% CI 0.70-0.94; P = 0.0051), respectively, after DuraGraft. Mortality was comparable between both groups at 1, 5, and 10 years. There was no statistically significant association between DuraGraft exposure and time to death starting at 30 or 1000 days (HR 0.91, 95% CI 0.76-1.09; P = 0.29). CONCLUSION: In this study, intraoperative treatment of SVGs with DuraGraft was associated with a lower risk of long-term adverse events suggesting that efficient intraoperative SVG treatment may reduce VGF-related complications post-CABG. These data warrant randomized clinical trials to validate these findings.

ABSTRACT

OBJECTIVE: Obesity and diabetes are associated with an increased liver cancer risk. However, most studies have examined all primary liver cancers or hepatocellular carcinoma, with few studies evaluating intrahepatic cholangiocarcinoma (ICC), the second most common type of liver cancer. Thus, we examined the association between obesity and diabetes and ICC risk in a pooled analysis and conducted a systematic review/meta-analysis of the literature. DESIGN: For the pooled analysis, we utilized the Liver Cancer Pooling Project, a consortium of 13 US-based, prospective cohort studies with data from 1,541,143 individuals (ICC cases n = 414). In our systematic review, we identified 14 additional studies. We then conducted a meta-analysis, combining the results from LCPP with results from the 5 prospective studies identified through September 2017. RESULTS: In the LCPP, obesity and diabetes were associated with a 62% [Hazard Ratio (HR) = 1.62, 95% Confidence Interval (CI): 1.24-2.12] and an 81% (HR = 1.81, 95% CI: 1.33-2.46) increased ICC risk, respectively. In the meta-analysis of prospectively ascertained cohorts and nested case-control studies, obesity was associated with a 49% increased ICC risk [Relative Risk (RR) = 1.49, 95% CI: 1.32-1.70; n = 4 studies; I2 = 0%]. Diabetes was associated with a 53% increased ICC risk (RR = 1.53, 95% CI: 1.31-1.78; n = 6 studies). While we noted heterogeneity between studies (I2 = 67%) for diabetes, results were consistent in subgroup analyses. Results from hospital-based case-control studies (n = 9) were mostly consistent, but these studies are potentially subject to reverse causation. CONCLUSIONS: These findings suggest that obesity and diabetes are associated with increased ICC risk, highlighting similar etiologies of hepatocellular carcinoma and intrahepatic cholangiocarcinoma. However, additional prospective studies are needed to verify these associations.
