Evaluation of the Effects of Sugary Beverages on the Health of Adolescent Students in Guangxi Based on Health System Function Scores

Objective:To evaluate the health effects of sugary beverage consumption among adolescent students in Guangxi.Methods:In three cities of Guangxi(Nanning,Liuzhou,and Guilin),we investigated the consumption of sugary beverages by distributing a self-administered Functional Assessment Questionnaire of Life Health System and a Dietary Behavior Questionnaire(this paper analyzes only the part of sugary beverage consumption)to adolescent students in four schools,aiming to find out the general health status of the students and also to assess the effects of sugary beverages on the functional system health of adolescent students.Results:A total of 953 adolescent students between the ages of 14 and 24 were surveyed.Among them,46.17%consumed sugary beverages once a week;37.46%consumed them 2-3 times;11.52%consumed them more than 3 times;and 4.83%consumed them every day.The mean score of Functional Assessment Questionnaire of Life Health System was 32.There was a positive correlation between the frequency of consumption of sugary beverages and the overall systemic function assessment score(P<0.05),and the rank of the total score elevated by 0.314 times for each increase in the level of consumption.Compared to those who drink sugary beverages at least once a day,drinking them once a week showed a statistically significant difference(P<0.05).However,there was no statistically significant difference between drinking 2-3 times a week and more than 3 times a week(P>0.05).The correlation between consuming sugary beverages once a week and 2-3 times a week and endocrine system scores was also statistically significant(P<0.05).Conclusion:More than half of the students in the surveyed areas consumed sugary beverages two or more times a week,and the higher the frequency of consumption,the higher the scores of systemic function assessment.Health education on sugar reduction among adolescents should be strengthened.

Critical care of obese patients during and after spine surgery

Obesity is one of the most prevalent health problems facing the United States today, with a recent JAMA articlepublished in 2014 estimating the prevalence of one third of all adults in the United States being obese. Also, due to technological advancements, the incidence of spine surgeries is growing. Considering these overall increases in both obesity and the performance of spinal surgeries, it can be inferred that more spinal surgery candidates will be obese. Due to this, certain factors must be taken into consideration when dealing with spine surgeries in the obese. Obesity is closely correlated with additional medical comorbidities, including hypertension, coronary artery disease, congestive heart failure, and diabetes mellitus. The pre-operative evaluation may be more difficult, as a more extensive medical evaluation may be needed. Also, adequate radiographic images can be difficult to obtain due to patient size and equipment limitations. Administering anesthesia becomes more difficult, as does proper patient positioning. Postoperatively, the obese patient is at greater risk for reintubation, difficulty with pain control, wound infection and deep vein thrombosis. However, despite these concerns, appropriate clinical outcomes can still be achieved in the obese spine surgical candidate. Obesity, therefore, is not a contraindication to spine surgery, and appropriate patient selection remains the key to obtaining favorable clinical outcomes.

Application of Multi-team Blood Glucose Management Model in Perioperative Period of General Surgery Patients

Objective:In order to explore the application effect of blood glucose management mode of multiteam cooperation in perioperative period of general surgery patients.Methods:The perioperative blood glucose control of 94 patients undergoing surgical treatment in general surgery from January 2016 to March 2019 was reviewed by Non-synchronous.According to the perioperative blood glucose management model of multi-team cooperation,the patients were divided into intervention group and control group.From January 2016 to January 2018,64 patients who did not implemented the multi-team blood glucose management model were the control group and from February 2018 to March 2019,30 patients who implemented the multi-team blood glucose management model were the intervention group,compared with two group about the differences in perioperative blood glucose.Results:It is no statistically significant about two group in highest and lowest blood sugar levels under fasting stats;during the fluid diet the blood sugar level of the intervention group was lower than control group(P<0.05),and when the patients was in the semifluid or food-feeding period,the highest and lowest blood sugar level is that the intervention group was lower than control group(P<0.05).The time of the blood sugar reaching the standard,the coincidence of complications rate and average hospitalization days in the intervention group were particularly lower than control group(P<0.05).Conclusion:If we adopt multiteam blood glucose management model can better control the perioperative blood glucose of patients undergoing general sugar.
