RESUMO
Background The number of persons with thyroid nodules has increased rapidly in recent years, and thyroid cancer caused by malignant nodules has become a key problem endangering the health of young and middle-aged groups in China. Objective To explore work and lifestyle influencing factors for developing thyroid cancer among young and middle-aged patients with thyroid nodules. Methods The subjects with thyroid nodules were reported by routine physical examines ordered at the Huadong Sanatorium. We conducted a 1∶4 matched case-control study in which 232 patients diagnosed with thyroid cancer from 2012 to 2022 were matched to 928 controls by gender and age (±5 years). A validated questionnaire was used to collect data on work and lifestyle behaviors. Univariate and multivariate logistic regression models were applied to explore potential relationships between selected factors (including environment, working hours, stress, diet, exercise, and mental health) and thyroid cancer. Spearman rank correlation was used to analyze the correlations between variables. Results The results of univariate logistic regression showed a history of thyroid cancer reported among first-degree relatives (OR=6.059, 95%CI: 1.007, 36.473), obesity (OR=1.973, 95%CI: 1.296, 3.004), noise and vibration exposure (OR=1.988, 95%CI: 1.143, 3.456), frequent stress (OR=2.093, 95%CI: 1.231, 3.559), frequent depression (OR=2.034, 95%CI: 1.048, 3.947), frequent anger (OR=1.791, 95%CI: 1.066, 3.012), frequent fried food diet (OR=1.535, 95%CI: 1.026, 2.297), and frequent fast food diet (OR=1.836, 95%CI: 1.048, 3.215) were risk factors for reporting thyroid cancer developing from thyroid nodules, while regular meals (OR=0.245, 95%CI: 0.061, 0.989) and frequent exercise (OR=0.571, 95%CI: 0.342, 0.952) were protective factors for reporting no thyroid cancer. The results of Spearman correlation analysis showed that body mass index was positively correlated with frequent fried food, fast food, and sugary beverage diets (r=0.123, 0.083, 0.077, P<0.01), and negatively correlated with frequent depression and anger (r=−0.090, −0.070, P<0.05). The results of multiple logistic regression found that a history of thyroid cancer reported among first-degree relatives (OR=6.712, 95%CI: 1.071, 42.066), obesity (OR=2.032, 95%CI: 1.321, 3.125), noise and vibration exposure (OR=1.991, 95%CI: 1.089, 3.637), and frequent stress (OR=2.468, 95%CI: 1.417, 4.300) were associated with an elevated risk of reporting thyroid cancer developing from thyroid nodules patients. Regular exercise (frequency≥3 times·week−1, > 30 min per episode) (OR=0.516, 95%CI: 0.300, 0.890) was associated with a lowered risk of reporting thyroid cancer. Conclusions Multiple risk factors associated with reporting thyroid cancer among young and middle-aged groups with thyroid nodules are identified, such as obesity, noise and vibration exposure, frequent stress, and lack of exercise.
RESUMO
Objective:To assess the relationship between serum total bilirubin and fundus arteriosclerosis in different genders.Methods:The physical examination data of Huadong Sanatorium in 2018 were analyzed, and a total of 26 275 people were included in this retrospective cross-sectional study. The age of this study was 18-86 (47.7±11.1) years old. Among them, there were 15 244 males (58.02%) and 11 031 females (41.98%). Participants were divided into 4 groups according to total bilirubin quartile values: Q1<11.50 μmol/L, Q2∶11.50-13.93 μmol/L, Q3∶13.94-17.14 μmol/L and Q4>17.14 μmol/L. The relationship between total serum bilirubin and fundus arteriosclerosis is determined using univariate and multivariate logistic regression analysis methods. The restricted cubic spline method was used to detect the dose-response relationship between total bilirubin and fundus arteriosclerosis. Results:In males, univariate analysis showed that high level of total bilirubin was a protective factor for fundus arteriosclerosis ( OR=0.87, 95% CI 0.78-0.97, P=0.012). After adjusting for other confounding factors, multivariate analysis showed that high level of total bilirubin remained as an independent protective factor for fundus arteriosclerosis ( OR=0.86, 95% CI 0.74-0.99, P=0.047). There was a linear dose-response relationship between total bilirubin level and fundus arteriosclerosis ( P=0.012). In females, univariate analysis showed that there were no statistically significant association between high level of total bilirubin and fundus arteriosclerosis ( OR=0.96, 95% CI 0.80-1.17, P=0.709). After adjusting for other confounding factors, multivariate analysis showed no statistically significant association between high level of total bilirubin and fundus arteriosclerosis ( OR=0.98, 95% CI 0.76-1.27, P=0.888). No linear dose-response relationship between total bilirubin level and fundus arteriosclerosis was found in females ( P=0.253). Conclusion:There are gender differences in the relationship between total bilirubin and fundus arteriosclerosis in this cohort. Elevated levels of total bilirubin are associated with fundus arteriosclerosis in males but not in females.
RESUMO
Objective To compare the clinical efficacy between covered stent and uncovered stent in transjuglar in-trahepatic portosystemic shunt (TIPS) .Methods Thirty patients with liver cirrhosis (portal hypertension), who received TIPS, were retrospectively studied.All patients were divided into two groups covered-stent group(n =20) and uncovered-stent group (n=10).For each patient, portal pressure was measured before and after operation, and the patency of shunt was evaluated by color Doppler ultrasound after operation.The mortality, recurrent bleeding rate and incidence of hepatic encephalopathy were analyzed by Fisher exact probability test.Results The TIPS treatment was successful in all patients, the portal pressure in the covered-stent group reduced from (3.78±0.50) kPa before operation to (2.21±0.44) kPa and that of the uncovered-stent group reduced from (3.67±0.48) kPa to (2.13±0.35) kPa.Twenty-six cases were postoperatively followed-up (17 cases in covered-stent group, 9 cases in uncovered-stent group).The follow-up period varied from 7 days to 62 months (median follow-up period was 23 months).Thirteen patients died of upper gastrointestinal bleeding and hepatic failure.The difference of mortality between covered-stent group (8/17) and uncovered-stent group (5/9) did not reach significant (P>0.05).The recurrent bleeding rate between the covered-stent group (5/17) and the uncovered-stent group (3/9) was not different too (P>0.05).The incidence of hepatic encephalopathy in the covered-stent group (4/17) was not different from that of the uncovered-stent group (2/9) (P> 0.05).The patency rates of 6 months and 12 months reached 100% in the covered-stent group, which were higher than those in the uncovered- stent group 77.8% (7/9) and 55.6% (5/9) (P<0.05) .Conclusions The patency rate of shunt at 12 months after TIPS was higher in the covered-stent group than the uncovered-stent group, while the mortality, recurrent bleeding rate and incidence of hepatic encephalopathy were not significantly different between the two groups.
