The cao vit gibbon Nomascus nasutus, also known as eastern black crested gibbon, is categorized as Critically Endangered on the IUCN Red List and was considered one of the world's 25 most threatened primates. The only known population occurs along the border between China and Viet Nam. Accurate information on population size and dynamics is critical for the species’ conservation, but population surveys conducted in only one country may over- or underestimate total population size because the home ranges of cao vit gibbon groups often cross the international border. In 2007 and 2016 we conducted two collaborative transboundary censuses of the cao vit gibbon populations in the Trung Khanh Cao Vit Gibbon Species and Habitat Conservation Area in Viet Nam and the Bangliang Gibbon National Nature Reserve in China. The results showed a population size of 102–110 in 2007, which increased to 107–136 in 2016. Our results indicate that previous surveys conducted separately in Viet Nam and China underestimated the global population size of this species. According to our more comprehensive surveys, the gibbon population is increasing slowly. The gibbons and their habitat are legally protected in both countries. Hunting and charcoal making have not been reported in this area since 2007. As habitat carrying capacity is a limiting factor, habitat restoration is required. However, lack of funding to protect the cao vit gibbon remains a challenge.

Evidence suggests that diets with high pro-inflammatory potential may play a substantial role in the origin of gastric inflammation. This study aimed to examine the association between the energy-adjusted dietary inflammatory index (E-DIITM) and gastric diseases at baseline and after a mean follow-up of 7.4 years in a Korean population. A total of 144,196 participants from the Korean Genome and Epidemiology Study_Health Examination (KoGES_HEXA) cohort were included. E-DII scores were computed using a validated semi-quantitative food frequency questionnaire. Multivariate logistic regression and Cox proportional hazards regression were used to assess the association between the E-DII and gastric disease risk. In the prospective analysis, the risk of developing gastric disease was significantly increased among individuals in the highest quartile of E-DII compared to those in the lowest quartile (HRquartile4vs1 = 1.22; 95% CI = 1.08–1.38). Prospective analysis also showed an increased risk in the incidence of gastritis (HRquartile4vs1 = 1.19; 95% CI = 1.04–1.37), gastric ulcers (HRquartile4vs1 = 1.47; 95% CI = 1.16–1.85), and gastric and duodenal ulcers (HRquartile4vs1 = 1.46; 95% CI = 1.17–1.81) in the highest E-DII quartile compared to the lowest quartile. In the cross-sectional analysis, the E-DII score was not associated with the risk of gastric disease. Our results suggest that a pro-inflammatory diet, indicated by high E-DII scores, is prospectively associated with an increased risk of gastric diseases. These results highlight the significance of an anti-inflammatory diet in lowering the risk of gastric disease risk in the general population.

Aim To examine the association between a pro‐inflammatory diet, estimated using the energy‐adjusted dietary inflammatory index (E‐DII), and the risk of periodontitis. Materials and Methods Study subjects from the Korean Genome and Epidemiology Study Health Examinee (KoGES_HEXA) cohort were included for cross‐sectional analysis (n = 168,378) using multivariate logistic regression and prospective analysis (n = 160,397) using Cox proportional hazard models respectively. DII and E‐DII scores were calculated based on the intake reported on a validated semi‐quantitative food frequency questionnaire (SQ‐FFQ). Results Cox proportional hazard models revealed a significantly increased risk of incident periodontitis in individuals consuming high E‐DII (more pro‐inflammatory) diets in the total population (HRquartile4vs1 = 1.29; 95% CI: 1.13–1.48; ptrend <.001) and in both men (HRquartile4vs1 = 1.36; 95% CI: 1.07–1.73; ptrend = 0.02) and women (HRquartile4vs1 = 1.27; 95% CI: 1.08–1.50; ptrend = .002). The association remained significant even after excluding cases diagnosed early in the follow‐up. In the cross‐sectional analysis, a significant association was observed between the E‐DII score and the prevalence of periodontitis among all study subjects (ORquartile4vs1 = 1.17; 95% CI: 1.03–1.34; ptrend = 0.01) and men (ORquartile4vs1 = 1.28; 95%CI: 1.01–1.63; ptrend <.001); however, the association did not reach statistical significance in women (ORquartile4vs1 = 1.13; 95% CI: 0.96–1.33; ptrend <.001). Conclusions Findings from the current study support the hypothesis that diets with high pro‐inflammatory potential increase the risk of periodontitis.
