Objective:To investigate the characteristics of cardiopulmonary exercise testing and risk factors for decreased aerobic capacity in children with non-acute asthma exacerbations, to assess their cardiopulmonary health and to provide a basis for improvement.Methods:A case-control study.Sixty-one children with non-acute asthma exacerbations treated at the Outpatient Department of Children′s Hospital of Soochow University from October 2022 to December 2023 and 22 control children during the same period were included.Binary Logistic regression was employed to assess risk factors for decreased aerobic capacity in children with asthma.Results:Among the included 61 children with non-acute asthma exacerbations, there were 33 cases in the chronic persistent phase (chronic persistent phase group) and 28 in the clinical remission phase(clinical remission group).There were 22 children in the control group.During the peak exercise phase of the cardiopulmonary exercise testing, the mean kilogram body weight oxygen uptake (VO 2/kg), the percentage of predicted kilogram body weight oxygen uptake, and metabolic equivalents (Met) in the chronic persistent phase group were lower than those in the control and clinical remission phase groups.The mean VO 2/kg recovery from the cardiopulmonary exercise testing in the first minute in the chronic persistent phase group was lower than that in the control and clinical remission phase groups.The median Met and ventilation per minute recovery in the chronic persistent phase group were lower than those in the control group.The median heart rate recovery in asthma children was lower than that in control children.The percentage of cardiopulmonary exercise testing abnormalities was higher in asthma children with symptoms after excise than that in asthma children without symptoms after excise.The percentage of decreased ventilation efficiency in asthma children with symptoms after excise was higher than that in asthma children without symptoms after excise.Multivariate regression analysis showed that a higher body mass index (BMI) ( OR=1.577, 95% CI: 1.113-2.235, P=0.010) and a higher peak respiratory reserve ( OR=1.103, 95% CI: 1.018-1.195, P=0.017) were risk factors of decreased aerobic capacity.The risk of decreased aerobic capacity in the chronic persistent phase was 7.949 times higher than that in the clinical remission phase ( OR=7.949, 95% CI: 1.290-48.996, P=0.025). Conclusions:The aerobic capacity is decreased and ventilatory recovery is slower in children with chronic persistent asthma than those in healthy children.The heart rate recovery in asthma children is slower than that in healthy children.A high BMI, a high peak respiratory reserve, and chronic persistence of asthma are independent risk factors for decreased aerobic capacity in children with non-acute asthma exacerbations.asthma.

Objective To investigate the relationship between tooth loss and the occurrence of esophageal cancer in a natural village in Wenfeng District, Anyang City, Henan Province. Methods A prospective cohort study was conducted to observe the occurrence of tooth loss and esophageal cancer among the asymptomatic residents of the natural village for 16 years from January 2008 to July 2024. Data were analyzed by chi-square test, binary logistic regression, and restricted cubic spline. Results Among the total population of 711 cases, 136 cases were lost to follow-up and 575 cases were included in the final statistics, including 45 cases with esophageal cancer. Significant statistical difference was found between esophageal cancer patients with and without tooth loss (P<0.05). Logistic regression analysis showed that tooth loss was associated with the occurrence of esophageal cancer (OR=3.977, 95%CI: 1.543-10.255). After the adjustment for confounders, tooth loss remained significantly associated with the occurrence of esophageal cancer (OR=3.038, 95%CI: 1.035-8.914). A nonlinear dose-response relationship was observed between the number of teeth lost and the incidence of esophageal cancer. When the number of teeth lost was less than 12, the risk of esophageal cancer increased with the number of teeth lost. When more than 12 teeth were lost, the risk of esophageal cancer decreased as the number of teeth lost increased. Conclusion Tooth loss is a risk factor for the occurrence of esophageal cancer in this natural village. When the number of teeth lost is less than 12, the risk of esophageal cancer increases with the number of teeth lost.

Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Objective To investigate the screening results and factors affecting abnormal detection rates among high-risk groups of esophageal cancer and to explore effective intervention measures. Methods We investigated and collected the information on gender, education level, age, marital status, symptoms of reflux esophagitis (heartburn, acid reflux, belching, hiccup, foreign body sensation in the pharynx, and difficulty swallowing), consumption of pickled vegetables, salt use, and esophageal cancer incidence of villagers in a natural village in Wenfeng District, Anyang City, Henan Province. Changes in reflux esophagitis symptoms in the high-incidence area of esophageal cancer before and after 16 years were observed, and the relationship of such changes with esophageal cancer was analyzed. Results In 2008, 711 cases were epidemiologically investigated, including 213 cases with one of the symptoms of reflux esophagitis such as heartburn, acid reflux, belching, hiccups, foreign body sensation in the pharynx, and difficulty swallowing (sorted in accordance with the abovementioned symptoms; if there are multiple symptoms, then the former is taken); 55 cases with at least two related symptoms, among which the most symptom was heartburn in 108 cases (15.1%); followed by acid reflux, belching, etc. In 2024, the same group of people was investigated, and eight people were missing because of relocation. A total of 703 people were successfully investigated, of which 189 cases (26.8%) had one of the symptoms of reflux esophagitis, such as heartburn (sorted in accordance with relevant symptoms, if there are multiple symptoms, then the former will be selected); 167 cases (23.7%) had at least two related symptoms, among which the most symptom was heartburn in 139 cases (19.7%); followed by acid reflux. Over 16 years, among the 703 people investigated, 45 cases had esophageal cancer and they had one or more of the abovementioned symptoms. No significant differences in the reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.26); no significant differences in the composition of reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.299). Conclusion The detection rate of reflux esophagitis-related symptoms in the population in a high-risk area of esophageal cancer has not decreased in the past 16 years, and the high-risk factors still exist. Esophageal cancer is closely related to reflux esophagitis, and clinical practice can provide early diagnosis and treatment for high-risk population.
