RESUMEN
AIM: Respiratory sarcopenia (RS) has been newly defined in a position paper by four professional organizations in Japan, and it is necessary to examine its incidence and influencing factors using this new definition. So far, little work has been undertaken; we therefore conducted a longitudinal study to fill this gap. METHODS: Our data were extracted from the China Health and Retirement Longitudinal Study. A total of 4301 older adults with complete data and without RS were chosen in 2011, of whom 3065 were followed up until 2015. The presence of low respiratory muscle strength plus low appendicular skeletal muscles mass was defined as RS based on t. A logistic regression model was used to identify the influencing factors for incident RS. RESULTS: After an average of 4 years of follow-up, the cumulative incidence of RS was 5.2%, and it was particularly high in participants aged >80 (20.9%). Logistic regression analysis showed that being unmarried/divorced/widowed (odds ratio [OR] = 1.85, 95% confidence interval [CI] = 1.28-2.66, P = 0.001), not having dyslipidemia (OR = 0.35, 95% CI = 0.19-0.65, P = 0.001), having digestive disease (OR = 1.56, 95% CI = 1.11-2.19, P = 0.010), asthma (OR = 2.77, 95% CI = 1.55-4.94, P = 0.001), edentulism (OR = 1.73, 95% CI = 1.24-2.42, P = 0.001), low handgrip strength (OR = 2.82, 95% CI = 1.99-3.99, P < 0.001), or low 5-m gait speed (OR = 1.92, 95% CI = 1.23-3.01, P = 0.004) were associated with a greater likelihood of developing RS. After further adjustment for age and body mass index, asthma, edentulism, and low handgrip strength remained significant. CONCLUSIONS: The identification and management of older adults with the influencing factors described above could be important in preventing RS. Geriatr Gerontol Int 2024; â¢â¢: â¢â¢-â¢â¢.
RESUMEN
Objective@#To establish a non-derivatization-PriME-ultra-high performance liquid chromatography-tandem mass spectrometry method for simultaneou determination of 9 kinds of biogenic amines in yellow rice wine.@*Methods@#Yellow rice wine samples were purified by PriME HLB solid phase extraction column purification, separated using Waters XSelect HSS T3 column (150 mm×2.1 mm, 3 μm), and qualified using multiple reaction monitoring mode, electrospray ion source positive ion and external standard method.@*Results@#There was a good linear relationship for the 9 kinds of biogenic amines at 2.0 to 500.0 μg/L (r≥0.996). The limit of detection was 0.1 to 0.2 mg/L, and the limit of quantitation was 0.3 to 0.6 mg/L. The spike recovery rate of 9 kinds of biogenic amines ranged from 83.5% to 108.6% at 0.1 and 1.0 mg/L, with relative standard deviations of 2.8% to 8.7%.@*Conclusion@#Non-derivation-prime ultra-high performance liquid chromatography-tandem mass spectrometry can be used for the rapid quantitative detection of biogenic amines in yellow rice wine.
RESUMEN
Objective@#To analyze the epidemiological characteristics of coronavirus disease 2019 ( COVID-19 ) in Shaoxing from January 23 to March 31, 2020, so as to provide basis for the prevention and control of COVID-19.@*Methods@#The information of the COVID-19 cases in Shaoxing were collected from the National Diseases Prevention and Control Information System and the field investigation by CDCs. A descriptive analysis was used for the epidemiological characteristics, including time, spatial and population distribution, clinical features and exposure history. @*Results@# Totally 42 confirmed cases of COVID-19 were reported by March 31, without deaths. The first case was reported on January 23 and the last one was on February 13. The onset of cases peaked in mid-to-late January. All the counties ( cities or districts ) had confirmed cases, 14 cases were reported in Yuecheng District. Twenty-five ( 59.52% ) cases were 45 years old or over. Thirteen ( 30.95% ) cases were engaged in business and eight ( 19.05% ) cases were unemployed. No cases were found among medical staff. The main clinical symptoms were fever, dry cough, fatigue and imaging features of pneumonia, with nine ( 21.43% ) severe cases and three ( 7.14% ) critical cases. There were 34 ( 80.95% ) imported cases, who mainly came from Hubei Province. Totally 1 955 close contacts were tracked down, among whom 4 cases were confirmed, with the infection rate of 0.20%.@*Conclusions@#The COVID-19 cases reported in Shaoxing were mainly aged 45 years or over, severe and imported from Hubei Province. There was no continuous transmission in the community, and no infection in medical staff or deaths.
RESUMEN
BACKGROUND: To test the independent and interactive associations of physical activity (PA) and body mass index (BMI) with age at menarche among Chinese adolescence. METHODS: We conducted a cross-sectional survey in two elementary schools in September 2015 in Shaoxing city, Zhejiang province, China. We used self-administered questionnaires to collect the information of the participators. Analyses were performed with logistic regression models, and the relative excess risk due to interaction (RERI), the attributable proportion because of the interaction (AP), and the synergy index (S) were used to evaluate the biological interaction. RESULTS: A total of 1530 middle school students from grade 1-3 were selected for this study, and we collected 1505 (98.366%) valid questionnaires for the last analyses. The mean age of menarche is 11.603 (SD=0.447)years. Students with overweight/obesity and without SMPA had the highest risks of early age of menarche (OR=3.507, 95%CI: 1.929-6.376) compared with women both with a normal BMI and with SMPA, and the RERI was 1.846 (95% CI: 0.415-4.107), meaning that there was positive interaction on the additive scale. CONCLUSION: Insufficient PA can significantly modify the association between obesity and early menarche risk. Therefore, the government and society should pay more attention to the promotion of PA throughout childhood and adolescence.
