ABSTRACT

Radical gastrectomy for gastric cancer results in various post-operative complications, and the influencing factors are complicated. The diagnosis, treatment and prevention of common complications have been reported in many literatures. However, there are few reports on the prevention and treatment of rare complications. Rare complications after radical gastrectomy are often overlooked due to their low incidence. In addition, there are few guidelines and expert consensus regarding to the rare complications. Therefore, clinicians may lack experience in the diagnosis, treatment and prevention of rare complications after radical gastrectomy. Based on the literature review and the author's experience, this article systematically reviews seven rare complications after radical gastrectomy (duodenal stump fistula, pancreatic fistula, chyle leakage, esophagomediastinal fistula, internal hernia, gastroparesis, and intussusception). This article aims to provide a comprehensive reference for the diagnosis, treatment and prevention of rare complications after radical gastrectomy for gastric cancer patients.

ABSTRACT

Objective: To analyze the epidemiological characteristics of waist circumference and abdominal obesity among Chinese children and adolescents aged 6-17 years. Methods: Data was from the samples of aged 6-17 years in the China National Nutrition and Health Surveillance program in 2010-2012. P(90) (the same age, the same sex) was used as the diagnostic value for abdominal obesity. Results: The overall waist circumference of children and adolescents in all the age groups appeared higher in males than that in females (P<0.000 1), higher in cities than that in the rural areas (P<0.05), and higher in children with high family income than those with middle or low family incomes (P=0.000 3). The rate of abdominal obesity in children and adolescents aged 6-17 years appeared as 11.2% on average and 10.7% and 11.8% for boys and girls, respectively but with no significant difference (P>0.05). Rates on abdominal obesity appeared as 13.2% and 8.5% for boys while as 12.3% and 11.2% for girls respectively, in urban or rural areas. As for the levels of family income, the abdominal obesity rates appeared as 15.8%, 11.5% and 8.8% respectively for boys while 13.5%, 11.9% and 11.6% respectively for girls, under high, middle and low levels of family income. Conclusion: The rate of abdominal obesity in boys seemed more responsive to the impact of income in urban or rural areas.

ABSTRACT

Objective: To analyze the relationship between family-related factors and the status of overweight and obesity in children and adolescents aged 6-17 years in China. Methods: Data were collected from the China National Nutrition and Health Surveillance in 2010-2012 program. A sample of 6 343 subjects aged 6-17 years was selected, with matched weight, education levels, household income and other family related factors of their parents. Univariate analysis and multivariate logistic regression were used to explore the relationship between family factors and overweight and obesity in school-aged children and adolescents. Results: After adjusted for age, gender and region, results from the multivariate logistic regression showed that both the overweight and obesity of children and adolescents were associated with maternal BMI (OR=1.83, 95%CI: 1.63-2.05), paternal BMI (OR=1.74, 95%CI: 1.57-1.94), mother's educational level (OR=1.24, 95%CI: 1.12-1.37) and household income (OR=1.30, 95%CI: 1.15-1.46). Conclusion: Factors as overweight or obesity status of the parents, mother's educational level and household income were positively correlated with the prevalence of overweight and obesity in Chinese children and adolescents.

ABSTRACT

Objective: To investigate the relationship between body mass index (BMI) and all-cause mortality in hypertensive population. Methods: All participants were selected from a prospective cohort study based on a rural population from Henan province, China. Cox proportional hazards regression models were used to estimate the associations of different levels of BMI stratification with all-cause mortality. Restricted cubic spline models were used to detect the dose-response relation. Results: Among the 5 461 hypertensive patients, a total of 31 048.38 person-years follow-up was conducted. The median of follow-up time was 6 years, and 589 deaths occurred during the follow-up period. Compared to normal weight group (18.5 kg/m(2)<BMI<24.0 kg/m(2)) the multivariate-adjusted hazard ratios for all-cause mortality associated with BMI levels (<18.5 kg/m(2), 24-28 kg/m(2), and ≥28 kg/m(2)) were 0.83 (95%CI: 0.37-1.87), 0.81 (95%CI: 0.67-0.97), and 0.72 (95%CI: 0.56-0.91), respectively. The dose-response analysis showed a nonlinear, reverse "S" shaped relationship (non-linearity P<0.001). Conclusion: Overweight or obese might have a protective effect on all-cause mortality in hypertensive population, which supports the "obesity paradox" phenomenon.

ABSTRACT

Objective: To understand the influence of diurnal temperature range (DTR) on influenza incidence in the elderly in Beijing and to conduct a subgroup analysis. Methods: The incidence data of daily influenza cases in the elderly and daily meteorological data from 2014 to 2016 in Beijing were collected for this study. A generalized additive model (GAM) was used to explore whether the relationship between daily influenza cases and DTR is a linear one. A distributed lag non-linear model (DLNM) was established to quantify the lagged effect of DTR on daily influenza incidence in the elderly. The model was also used to estimate the effects of DTR on daily influenza incidence among various subgroups. Results: A total of 4 097 influenza cases in the elderly were notified during study period. The mean DTR was 10.153 ℃. A linear relationship between daily influenza incidence and DTR was detected by using GAM. DTR was significantly associated with daily influenza incidence between lag0 and lag5 with a maximal effect at lag0. An 1 ℃ increase of DTR was associated with a 2.0% increase in daily influenza incidence in the elderly (95%CI: 0.9%-3.0%). The RR values of males, females, people aged 60-69 years, people aged ≥70 years were 1.018 (95%CI: 1.005-1.032), 1.021(95%CI: 1.007-1.035), 1.012 (95%CI: 1.002-1.022), 1.025 (95%CI: 1.012-1.039), respectively. The influencing time of DTR on females (lag6) was longer than males (lag2). Conclusions: DTR was associated with increased risk of influenza in the elderly in Beijing. It is necessary to take targeted measures in the elderly to control the incidence of influenza when DTR becomes greater.

ABSTRACT

To control avian coccidiosis with drug-independent strategy effectively and safely, multivalent hyperimmune egg yolk immunoglobulin [IgY] was prepared and its ability to protect against Eimeria tenella infection was evaluated. Hens were orally immunized with live oocysts of 5 species of Eimeria for six times, antibody titers in serum and yolk were monitored by indirect enzyme-linked immunosorbent assay. The specific IgY was isolated, purified and lyophilized. IgY powder was orally administrated as dietary supplement in newly hatched chicks at various dosages. Birds were orally challenged with 10000 sporulated oo-cysts of E. tenella at 10 days of age, weighed and killed at 8 days post challenge, and the protective effect was assessed. The average yield of IgY was 9.2 mg/ml yolk, the antibody titer of IgY reached to 1:163840 per mg with the purity up to 98%. Chickens fed IgY resulted in reduced mortality, increased body weight gain [BWG], reduced oocyst shedding, reduced caecal lesion score and increased anti-coccidial index. In terms of BWG and caecal lesion, IgY significantly enhanced the resistance of bird at >/= 0.05% of IgY in the diet when compared with the challenged control group [P<0.05]. No significant difference was observed at dosage >/= 0.5% and 1.0% when BWG and caecal lesion were compared with the sodium salinomycin control group, respectively [P>0.05]. Supplementing newly hatched chicks with Eimeria-specific IgY represents a promising strategy to prevent avian coccidiosis
