Objective:To analyze the incidence trends of malignant tumors in the elderly population aged over 60 years in Qidong City from 1972 to 2021, as well as to predict the incidence rate for the next decade.Methods:Data were obtained from the Qidong Cancer Registry and Reporting System.The crude incidence rate(CR), age-standardized incidence rate using the Chinese standard population(ASRC), and age-standardized incidence rate based on Segi's world standard population(ASRW)were calculated.Joinpoint regression analysis was conducted using Joinpoint 4.9.1.0 software to determine the average annual percentage change(AAPC)in incidence.Additionally, the ARIMA model implemented in SAS 9.2 software was utilized for time series analysis to forecast incidence trends over the forthcoming 10 years.Results:In Qidong City, a total of 87, 401 malignant tumors were reported in the elderly population.The ASRW increased from 736.85 per 100, 000 in the years 1972-1976 to 1 056.33 per 100, 000 in 2017-2021.Specifically, the ASRW for males rose from 968.56 per 100, 000 to 1 332.75 per 100, 000, while the ASRW for females increased from 550.62 per 100, 000 to 825.44 per 100, 000, with AAPC values of 1.16%, 0.94%, and 1.44% over 50 years(all P<0.001).The incidence trend exhibited an upward trajectory with age, peaking in the 75-79 age group.The AAPC values for the incidence rates in the age groups of 60-64, 65-69, 70-74, 75-79, and those aged over 80 were 0.64%, 0.93%, 0.92%, 2.02%, and 2.44%, respectively(all P<0.001).Among the various cancers, lung cancer, which ranked first, saw an increase in ASRW from 100.87 per 100, 000 in 1972-1981 to 248.84 per 100, 000 in 2012-2021.In contrast, gastric cancer, ranked second, decreased from 216.23 per 100, 000 in 1972-1981 to 103.54 per 100, 000 in 2012-2021.Liver cancer, ranked third, fluctuated from 113.47 per 100, 000 in 1972-1981 to 125.13 per 100, 000 in 2012-2021.Colorectal cancer, ranked fourth, increased from 40.06 per 100, 000 in 1972-1981 to 123.47 per 100, 000 in 2012-2021, while esophageal cancer, ranked fifth, decreased from 63.42 per 100, 000 in 1972-1981 to 28.65 per 100, 000 in 2012-2021.The AAPC values over 50 years for these cancers were 2.25%, -1.89%, 0.36%, 3.13%, and -1.86%, respectively(all P<0.05).Projections indicate that by 2031, the incidence of malignant tumors among the elderly population in Qidong will reach 1 253.84 per 100, 000, with estimates of 1 566.67 per 100, 000 for males and 983.14 per 100, 000 for females. Conclusions:The incidence of malignant tumors among the elderly population in Qidong City is increasing.Common types of cancer in this demographic include lung cancer, gastric cancer, liver cancer, colorectal cancer, and esophageal cancer.Notably, lung cancer, liver cancer, and colorectal cancer are on the rise and should be prioritized in cancer prevention and control efforts.

Objective:To understand the status and influencing factors of social isolation in elderly individuals with chronic diseases.Methods:A multi-stage sampling method was used to select elderly individuals from eight communities or villages in Hefei from July to September 2022. The study employed a general information survey, the Lubben Social Network Scale (LSNS-6) , the Geriatric Depression Scale (GDS-15) , the Social Support Rating Scale (SSRS) , and the Personal Social Capital Scale 16 (PSCS-16) . Binary Logistic regression analysis was used to explore the factors influencing social isolation in elderly individuals with chronic diseases.Results:A total of 1 133 elderly individuals were surveyed, among which 538 had chronic diseases. Among the 538 elderly individuals with chronic diseases, 209 were socially isolated, resulting in a social isolation rate of 38.8%. Binary Logistic regression analysis revealed that living area, fear of falling, depression, social capital, and social support were significant factors influencing social isolation ( P<0.05) . Conclusions:The social isolation rate among elderly individuals with chronic diseases is high. Special attention should be given to elderly individuals living in rural areas, those who fear falling, and those experiencing depression. Additionally, improving social capital and social support can help alleviate social isolation in these elderly individuals.

Objective:To explore the potential categories and influencing factors of attitudes to aging among the elderly in nursing homes.Methods:Convenience sampling was used to select elderly from 15 nursing homes in Anhui Province from March to July 2024 for the study. The survey was conducted using the General Information Questionnaire, Attitudes to Ageing Questionnaire, Belongingness Scale for Older Adults in Nursing Facilities, and the Lubben Social Network Scale. Mplus 8.3 was used to conduct a latent profile analysis, and multivariate Logistic regression was employed to explore the factors influencing the latent categories of attitudes toward aging among the elderly in nursing facilities.Results:A total of 370 questionnaires were distributed, and 366 valid questionnaires were recovered, with an effective recovery rate of 98.9%. The attitudes to aging of 366 elderly of nursing facilities were expressed in three potential categories, namely, negative-perceived type (48.6%), moderate-low psychosocial loss type (35.0%), and positive and optimistic-comprehensive type (16.4%). Multicategorical Logistic regression analysis showed that the number of children, location of the nursing home, educational level, self-rating health, belongingness to the nursing home, and social network were the influencing factors of the potential categories of attitudes to aging among the elderly in the nursing home, and the difference was statistically significant ( P<0.05) . Conclusions:There is group heterogeneity in the attitudes to aging among the elderly in nursing homes. Healthcare professionals should focus on negative-perceived elderly and provide targeted interventions based on the potential categories of factors influencing their attitudes to aging.

Objective:To improve the diagnosis and treatment of thyroid carcinoma in flying personnel by analyzing the clinical characteristics of thyroid carcinoma.Methods:The clinical and pathological data of flying personnel with thyroid carcinoma diagnosed and treated by Air Force Medical Center of PLA from January of 2010 to December of 2022 were retrospectively analyzed. Clinical characteristics such as age, flying hours, aircraft types, thyroid function at diagnosis, and pathological characteristics such as tumor site, tumor size, lymph node metastasis, calcification and sand and Ki-67 positive ratio were collected, and the clinical and pathological characteristics were statistically analyzed.Results:Thyroid nodule was found as the first diagnosis of thyroid carcinoma in 57 flying personnel. The age of onset was 22-58 years old, the median age was 37 years old, the flying hours was 4-18 000 h, and the median flying hours was 2 000 h. Thyroid carcinoma was detected in both thyroid glands, and the histological type was papillary thyroid carcinoma. Thyroid function was normal in most cases when thyroid carcinoma was detected. Lymph node metastasis of thyroid carcinoma was low positively correlated with tumor size ( r=0.304, P=0.021), and was low positively correlated with the positive proportion of Ki-67 ( r=0.360, P=0.006). Other clinical and pathological characteristics did not show clear correlation. With the extension of flying hours, the incidence of lymph node metastasis of thyroid carcinoma increased, and the difference was statistically significant ( χ2=6.32, P=0.012). There was no statistical difference among the clinical characteristics of flying personnel with different age and aircraft types ( P>0.05). Conclusions:The thyroid carcinoma is usually diagnosed without clinical symptoms and the thyroid function is basically normal. The thyroid ultrasound examination should be emphasized during physical examination, and further examination should be conducted for the flying personnel with thyroid nodules.

OBJECTIVE: To explore the genetic basis for four Chinese pedigrees affected with Waardenburg syndrome (WS). METHODS: Four WS probands and their pedigree members who had presented at the First Affiliated Hospital of Zhengzhou University between July 2021 and March 2022 were selected as the study subjects. Proband 1, a 2-year-and-11-month female, had blurred speech for over 2 years. Proband 2, a 10-year-old female, had bilateral hearing loss for 8 years. Proband 3, a 28-year-old male, had right side hearing loss for over 10 years. Proband 4, a 2-year-old male, had left side hearing loss for one year. Clinical data of the four probands and their pedigree members were collected, and auxiliary examinations were carried out. Genomic DNA was extracted from peripheral blood samples and subjected to whole exome sequencing. Candidate variants were verified by Sanger sequencing. RESULTS: Proband 1, with profound bilateral sensorineural hearing loss, blue iris and dystopia canthorum, was found to have harbored a heterozygous c.667C>T (p.Arg223Ter) nonsense variant of the PAX3 gene, which was inherited from her father. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as pathogenic (PVS1+PM2_Supporting+PP4), and the proband was diagnosed with WS type I. Proband 2, with moderate sensorineural hearing loss on the right side and severe sensorineural hearing loss on the left side, has harbored a heterozygous frameshifting c.1018_1022del (p.Val340SerfsTer60) variant of the SOX10 gene. Neither of her parents has harbored the same variant. Based on the ACMG guidelines, it was classified as pathogenic (PVS1+PM2_Supporting+PP4+PM6), and the proband was diagnosed with WS type II. Proband 3, with profound sensorineural hearing loss on the right side, has harbored a heterozygous c.23delC (p.Ser8TrpfsTer5) frameshifting variant of the SOX10 gene. Based on the ACMG guidelines, it was classified as pathogenic (PVS1+PM2_Supporting+PP4), and the proband was diagnosed with WS type II. Proband 4, with profound sensorineural hearing loss on the left side, has harbored a heterozygous c.7G>T (p.Glu3Ter) nonsense variant of the MITF gene which was inherited from his mother. Based on the ACMG guidelines, the variant was classified as pathogenic (PVS1+PM2_Supporting+PP4), and the proband was diagnosed with WS type II. CONCLUSION By genetic testing, the four probands were all diagnosed with WS. Above finding has facilitated molecular diagnosis and genetic counseling for their pedigrees.

Cancer-related fatigue (CRF) is a common symptom which associated with cancer itself or cancer treatments. CRF will not only interrupt the patient's treatment, but also affect the patient's quality of life seriously. To date, the pathogenesis of CRF is still unclear, and recognized effective treatment is lacking. It is the precondition of establishing standardized animal models for CRF to find effective treatments. This paper summarizes the animal model of CRF in order to find suitable methods, and distinguish the effects of different interventions.
