Objective To analyze and summarize the clinical characteristics of foreign body incarceration in upper digestive tract, and to explore the risk factors of its complications. Methods The clinical data of patients with foreign bodies in the upper digestive tract treated in the Affiliated Hospital of Zunyi Medical University between January 1, 2012 and December 31, 2021 were retrospectively analyzed, including demographic data, foreign body type, incarceration site, incarceration time, causes, symptoms, treatment methods and complications of foreign body incarceration. Logistic regression analysis was used to explore the risk factors of complications. Results A total of 721 patients were finally included, ranging in age from 3 months to 90 years old, with an average age of 26.76 years. The proportion of foreign bodies in the upper digestive tract in patients ≤14 years old was the highest (51.18%), and the duration of foreign body incarceration<12 hours was the highest (55.34%). The most common sharp foreign bodies in the upper digestive tract were animal bones (228 cases), and the most common round shaped foreign bodies were coins (223 cases). The most common impaction site was the upper esophageal segment (85.02%). 105 patients (14.56%) had complications, and perforation was the most common (5.55%). Logistic regression analysis showed that age [odds ratio (OR)=0.523, 95% confidence interval (CI) (0.312, 0.875), P=0.014], foreign body type [OR=0.520, 95%CI (0.330, 0.820), P=0.005], incarceration site [OR=2.347, 95%CI (1.396, 3.947), P=0.001], incarceration time [OR=0.464, 95%CI (0.293, 0.736), P=0.001] were the influencing factors of complications. Conclusions The majority of foreign bodies in the upper digestive tract are animal bones. The incidence of complications increase in patients with age ≥ 60 years, sharp foreign body edges, incarceration in the upper segment of the esophagus, and long incarceration time. It is recommended to remove the sharp foreign bodies incarcerated in the upper segment of the esophagus from the elderly as soon as possible.

Methods Between September 2008 and March 2011, 44 pairs of reproduction-needed couples were investigated by retrospective questionnaire. The risk factors of spontaneous abortion were analyzed. Results The spontaneous abortion rate was 22.9%; 11.1% females had the menstruation changes. The difference in the rate of the menstruation changes between the females had spontaneous abortion history and the ones didn′t had the history was not significant (χ2=0.58，Pgt;0.05). Conclusions The females after the earthquake may have menstruation changes; the spontaneous abortion rate in reproduction-needed couples after the earthquake is obviously higher than that in the normal couples. The risk factors may include the environment and the age.

Objective To investigate the risk factors of perioperative red blood cells transfusion for coronary artery bypass grafting (CABG) surgery. Method We retrospectively analyzed the clinical data of 534 patients underwent CABG in our hospital from January to March 2014 year. Those patients were divided into two groups:an on-pump coronary artery bypass grafting group (on-pump group) and an off-pump coronary artery bypass grafting group (off-pump group). There were 185 males and 54 females with a mean age of 59.1±9.4 years in the on-pump group. There were 233 males and 62 females with a mean age of 60.3±8.5 years in the off-pump group. Preoperative data, the relative parameters of extracorporeal circulation, the quantity of red blood cells transfusion of those two groups were compared. risk factors associated with red blood cells transfusion were evaluated by multivariate logistic regression analysis. Results The risk factors of perioperative red blood cells transfusion were age (OR=1.04, 95% CI 1.02-1.07, P=0.001) , weight (OR=0.95, 95% CI 0.93-0.97, P<0.001) , smoking (OR=0.61, 95% CI 0.39-0.94, P=0.027) , preoperative level of HCT (OR=0.90, 95% CI 0.85-0.96, P=0.001) and cardiopulmonary bypass (CPB) (OR=4.90, 95% CI 3.11-7.71, P<0.001) . During CPB, the nadir hemoglobin (nHb) (OR=0.63, 95% CI 0.47-0.84, P=0.002) was the only independent risk factor of red blood cell transfusion. Conclusions Age, weight, non-smoking, preoperative level of HCT, CPB are the risk factors for patients underwent CABG perioperatively and the lowest level of Hb in CPB is an independent risk factor of perioperative red blood cells transfusion.
Objective To analyze the risk factors for duration of mechanical ventilation in critically ill patients. Methods Ninety-six patients who received mechanical ventilation from January 2011 to December 2011 in intensive care unit were recruited in the study. The clinical data were collected retrospectively including the general condition, underlying diseases, vital signs before ventilation, laboratory examination, and APACHEⅡ score of the patients, etc. According to ventilation time, the patients were divided into a long-term group ( n = 41) and a short-term group ( n = 55) . Risk factors were screened by univariate analysis, then analyzed by logistic regression method.Results Univariate analysis revealed that the differences of temperature, respiratory index, PaCO2 , white blood cell count ( WBC) , plasma albumin ( ALB) , blood urea nitrogen ( BUN) , pulmonary artery wedge pressure ( PAWP) , APACHEⅡ, sex, lung infection in X-ray, abdominal distention, and complications between two groups were significant.With logistic multiple regression analysis, the lower level of ALB, higher level of PAWP, lung infection in X-ray, APACHE Ⅱ score, abdominal distention, and complications were independent predictors of long-term mechanical ventilation ( P lt;0. 05) . Conclusion Early improving the nutritional status and cardiac function, control infection effectively, keep stool patency, and avoid complications may shorten the duration of mechanical ventilation in critically ill patients.
Objective To investigate the characteristics, complications, and influencing factors of pediatric foreign body ingestion, providing clinical references for prevention and management. Methods A retrospective analysis was conducted on pediatric cases of foreign body ingestion treated at West China Hospital of Sichuan University between June 2007 and September 2019. Patients were stratified by age into ≤5 years, 6-10 years, and >10 years groups. Foreign body types, impaction sites, and complication rates were compared across age groups. Univariate analysis and multivariate logistic regression were performed to identify risk factors for complications. Results A total of 610 pediatric cases of foreign body ingestion were enrolled. Foreign body ingestion predominantly occurred in children ≤5 years (n=472, 77.38%), followed by 6-10 years (n=100, 16.39%) and >10 years (n=38, 6.23%). Foreign body types varied significantly by age (P<0.05): coins predominated in ≤5-year-olds (57.20%), while food-related objects were most common in >10-year-olds (52.63%). The most frequent impaction site was the upper esophagus, accounting for 48.31%, 44.00%, and 60.53% in the three age groups, respectively. Univariate analysis identified age, foreign body type, and location as significant predictors of complications (P<0.05). Multivariate logistic regression demonstrated that oropharynx and esophageal impaction (reference: stomach) [odds ratio (OR)=4.699, 95% confidence interval (CI) (2.456, 8.996), P<0.001] and high-risk foreign body types [OR=3.538, 95%CI (2.045, 6.122), P<0.001] were independent risk factors for complications, whereas increasing age had a protective effect [OR=0.418, 95%CI (0.252, 0.694), P=0.001]. Conclusions Younger children are at higher risk of foreign body ingestion, while increasing age is protective against complications. High-risk foreign body types and oropharynx and esophageal impaction significantly increase complication risks. Strengthening parental education, preventive measures against high-risk objects, and enhancing clinicians’ vigilance for complex cases are essential to reduce complications.
ObjectiveTo investigate the significance of using the term "high-normal blood pressure" and its intervention in the early stage. MethodsIn 1992 and 2007, we performed two similar investigations focusing on cardiovascular risk factors in 711 people in Chengdu city. Since 114 individuals were diagnosed with hypertension, 597 people without hypertension were eligible and divided into two groups:the normal-pressure[<120/80 mm Hg (1 mm Hg=0.133 kPa)] group and the high-normal blood pressure (systolic blood pressure 120-139 mm Hg and/or diastolic blood pressure 80-89 mm Hg) group. Data in the two investigations were compared to explore the relationship among high-normal blood pressure, cardiovascular disease (CVD) and hypertension. ResultsThe high-normal blood pressure group had a higher level of CVD risk factors both in 1992 and 2007, and the 15-year cumulative incidence of hypertension in the high-normal blood pressure group was higher than that of normal-pressure group (91.2% vs. 22.2%, P<0.001). After adjusting for serum lipid, body weight and other CVD risk factors, high-normal blood pressure could predict the progression into hypertension[HR=5.354, 95% CI (4.094, 7.002), P=0.001]. There was no statistics difference in CVD prevalence in the two groups in 1992, but in 2007 the prevalence of CVD tended to be higher in the high-normal blood pressure group (6.6% vs. 3.1%, P=0.052). ConclusionHigh-normal blood pressure is a special stage of blood pressure with high level of CVD risk factors and high potential to progress into hypertension. The term should be emphasized and intervention should be done in the early stage for high-normal blood pressure people to prevent from hypertension and CVD.
The pathogenesis of diabetic retinopathy (DR) is complex and there are many related risk factors. It is related to the course of diabetes, blood glucose, blood pressure, and blood lipids, among which the course of disease and hyperglycemia are recognized main risk factors. In addition, other factors which include heredity, gender, age, obesity, pregnancy, insulin use, can also affect the occurrence and development of DR, but there is no unified conclusion about its correlation. A comprehensive understanding of the risk factors that affect DR can provide new ideas for the prevention, diagnosis, treatment, and intervention of DR.
ObjectiveTo explore risk factors of blood transfusion during liver transplantation and construct its prediction model. MethodsThe patients underwent liver transplantation who met the inclusion and exclusion criteria of this study from March 2020 to December 2020 in the Beijing Youan Hospital of Capital Medical University were retrospectively collected. The univariate and logistic multivariate analysis were used to evaluate the risk factors of blood transfusion during liver transplantation and construct the prediction model for intraoperative blood transfusion. ResultsA total of 151 eligible liver transplantation patients were collected in this study, including 51 non-transfusion patients and 100 transfusion patients. The univariate analysis results showed that the differences of primary diagnosis, preoperative hemoglobin (Hb), platelet count, prothrombin time, international normalized ratio, Child-Turcotte-Pugh score, and end-stage liver disease (MELD) score were statistically different between them (P<0.05). The above variables selected by the univariate analysis were selected by stepwise method, then the preoperative Hb and MELD score were selected into the multivariate logistic regression analysis, the results showed that the preoperative Hb≤113 g/L and MELD score ＞14 increased the risk of blood transfusion during liver transplantation [Hb: OR=6.652, 95%CI (2.282, 19.392), P<0.001; MELD score: OR=16.037, 95%CI (6.336, 40.592), P<0.001]. The logistic regression model predicted the area under receiver operating characteristic curve was 0.873 [95%CI (0.808, 0.919), P<0.001], the sensitivity and specificity were 91.0% and 67.5%, respectively, Youden index was 0.674, the accuracy was 86.1%. ConclusionsResults of this study suggest that preoperative Hb ≤113 g/L and MELD score＞14 increase risk of blood transfusion during liver transplantation. Logistic regression model constructed according to preoperative Hb and MELD score has a better sensitivity and specificity of intraoperative blood transfusion.
