BACKGROUND: Physical activity, sedentary behavior (SB), and sleep duration are associated with brain health. Effects of those on developing Parkinson's disease (PD) are poorly investigated. This study aimed to examine the independent and joint associations of physical activity, SB, sleep with PD risk. METHODS: We analyzed data on 401,697 participants from the UK Biobank cohort, which was enrolled in 2006-2010. Physical activities were measured based on a questionnaire. Sleep and SB time were defined through self-reported total number of hours. Models fitted with restricted cubic spline were conducted to test for linear and non-linear shapes of each association. Cox proportional hazards regression models were used to estimate the association of three modifiable behaviors. RESULTS: Our analytic sample included 401,697 participants with 3030 identified cases of PD (mean age, 63 years; 62.9% male). PD risk was 18% lower in the high total physical activity group (95% CI, 0.75-0.90), 22% lower in the high leisure-time physical activity (LTPA) group (95% CI, 0.71-0.86) compared with the low level and 14% higher in the high sleep duration group (95% CI, 1.05-1.24) compared to moderate group. Total SB time was irrelevant with PD risk, while high TV viewing showed a 12% increase of PD risk compared to the low group (95% CI, 1.02-1.22). Low computer use (0 h/day) was associated with a 14% higher risk compared to 1 h/day use (95% CI, 1.04-1.26). Those associations were independent. A combination of 7 h/day sleep, moderate-to-high computer use, and moderate-to-vigorous intensity of LTPA showed lowest PD risk (HR, 0.70; 95% CI, 0.57-0.85). CONCLUSIONS Physical activity, SB, and sleep were associated with PD risks separately. Our findings emphasize the possibility for changing these three daily activities concurrently to lower the risk of PD. These findings may promote an active lifestyle for PD prevention.

BACKGROUND: Neuroticism has been associated with numerous health outcomes. However, most research has focused on a single specific disorder and has produced controversial results, particularly regarding mortality risk. Here, we aimed to examine the association of neuroticism with morbidity and mortality and to elucidate how neuroticism affects trajectories from a healthy state, to one or more neuroticism-related disorders, and subsequent mortality risk. METHODS: We included 483,916 participants from the UK Biobank at baseline (2006-2010). Neuroticism was measured using the Eysenck Personality Questionnaire. Three clusters were constructed, including worry, depressed affect, and sensitivity to environmental stress and adversity (SESA). Cox proportional hazards regression and multistate models were used. Linear regression was used to examine the association between neuroticism and immune parameters and neuroimaging measures. RESULTS: High neuroticism was associated with 37 non-overlapping diseases, including increased risk of infectious, cardiometabolic, neuropsychiatric, digestive, and respiratory diseases, and decreased risk of cancer. After adjustment for sociodemographic variables, physical measures, healthy behaviors, and baseline diagnoses, moderate-to-high neuroticism was associated with a decreased risk of all-cause mortality. In multistate models, high neuroticism was associated with an increased risk of transitions from a healthy state to a first neuroticism-related disease (hazard ratio [HR] [95% confidence interval (CI)] = 1.09 [1.05-1.13], P  <0.001) and subsequent transitions to multimorbidity (1.08 [1.02-1.14], P  = 0.005), but was associated with a decreased risk of transitions from multimorbidity to death (0.90 [0.84-0.97], P for trend = 0.006). The leading neuroticism cluster showing a detrimental role in the health-illness transition was depressed affect, which correlated with higher amygdala volume and lower insula volume. The protective effect of neuroticism against mortality was mainly contributed by the SESA cluster, which, unlike the other two clusters, did not affect the balance between innate and adaptive immunity. CONCLUSION This study provides new insights into the differential role of neuroticism in health outcomes and into new perspectives for establishing mortality prevention programs for patients with multimorbidity.

Tuberculosis (TB) is one of the deadly diseases caused by Mycobacterium tuberculosis (Mtb), which presents a significant public health challenge. Treatment of TB relies on the combination of several anti-TB drugs to create shorter and safer regimens. Therefore, new anti-TB agents working by different mechanisms are urgently needed. FtsZ, a tubulin-like protein with GTPase activity, forms a dynamic Z-ring in cell division. Most of FtsZ inhibitors are designed to inhibit GTPase activity. In Mtb, the function of Z-ring is modulated by SepF, a FtsZ binding protein. The FtsZ/SepF interaction is essential for FtsZ bundling and localization at the site of division. Here, we established a yeast two-hybrid based screening system to identify inhibitors of FtsZ/SepF interaction in M. tuberculosis. Using this system, we found compound T0349 showing strong anti-Mtb activity but with low toxicity to other bacteria strains and mice. Moreover, we have demonstrated that T0349 binds specifically to SepF to block FtsZ/SepF interaction by GST pull-down, fluorescence polarization (FP), surface plasmon resonance (SPR) and CRISPRi knockdown assays. Furthermore, T0349 can inhibit bacterial cell division by inducing filamentation and abnormal septum. Our data demonstrated that FtsZ/SepF interaction is a promising anti-TB drug target for identifying agents with novel mechanisms.

Objective To study the effect of self-monitoring of blood glucose information management platform based on the medical consortium on the level of blood glucose control by improving the implementation rate of self-monitoring of blood glucose prescriptions for type 2 diabetes patients in the community.Methods A convenient sampling method was used to select 121 patients with type 2 diabetes from April 2021 to April 2023 who were enrolled in a community of a tertiary hospital medical consortium in Beijing.They were randomly divided into 61 patients in an experimental group and 60 patients in a control group.The control group received routine blood glucose monitoring and guidance education,while the experimental group was managed by a self-monitoring of blood glucose information management platform based on the medical consortium with nurses as the main body.Glycated hemoglobin,glucose test,fasting blood sugar,blood glucose 2 hours after meal,and the completion of self blood glucose monitoring prescriptions were evaluated and analyzed in the first week and the twelfth week of the 2 groups.Results 61 cases in the experimental group and 58 cases in the control group completed the follow-up,and the patients who completed the follow-up were analyzed.There was no statistically significant difference in glycated hemoglobin between the 2 groups at baseline(P=0.117).After 12 weeks,the reduction standard-reaching rate in glycated hemoglobin in the experimental group was significantly different from that in the control group(P=0.014).The number of self-monitoring of fasting blood glucose and the total number of other time periods in experimental group were significantly higher than those in the control group(P＜0.001);the implementation rate of self-monitoring prescription in the experimental group was better than that in the control group(P＜0.001).Conclusion A self blood glucose monitoring information platform was built to manage community type 2 diabetes patients,so that patients can master and implement the personalized blood glucose monitoring prescription formulated by the medical union team with nurses as the main body,and it is conducive to improving the frequency of blood glucose monitoring and the level of blood glucose control of diabetes patients.

Objective:To explore the status quo of self-reported hearing impairment and physical function among the elderly in China, and to analyze the correlation between the two.Methods:This study was a cross-sectional study. From January to May 2022, the elderly in 8 provinces or municipalities in East China, South China, Central China, North China, and Southwest China were selected as research objects by convenience sampling. The General Information Questionnaire, the Mini-Mental State Examination (MMSE) and the Short Physical Performance Battery (SPPB) were used for the investigation. Multi-category Logistic regression analysis was used to explore the correlation between physical function impairment and self-reported hearing impairment in the elderly. A total of 5 996 questionnaires were collected, of which 5 822 were valid questionnaires, and the valid recovery rate was 97.1%.Results:Among the 5 822 elderly people, 869 (14.9%, 869/5 822) elderly people self-reported hearing impairment. The total score of SPPB in 5 822 elderly people was (5.89±4.26) , of which 2 899 (49.8%) elderly had low physical function, 1 454 (25.0%) elderly had moderate physical function, and 1 469 (25.2%) elderly had high physical function. Multi-category Logistic regression analysis showed that the elderly with self-reported hearing impairment had a high risk of developing low physical function ( OR=2.214, P<0.05) and moderate physical function ( OR=1.432, P<0.05) . In addition, cognitive impairment, female gender, advanced age, low body mass index (BMI) , low monthly household income, and having three or more chronic diseases were also common risk factors for low and moderate physical function ( P<0.05) . Low education level, unmarried status, living in rural areas and irregular exercise were specific risk factors for low physical function ( P<0.05) . Conclusions:The elderly have poor physical function, and the elderly with self-reported hearing impairment had a high risk of developing low physical function. Attention should be paid to the hearing screening of the elderly. For the elderly with self-reported hearing impairment, they should be encouraged to communicate with others to reduce social loneliness, and participate in sports as much as possible under the premise of ensuring safety, so as to maintain and improve their physical function.

Objective:To evaluate the efficacy of combination of toy and cartoon video-assisted admission in preventing agitation during recovery from general anesthesia in preschool children.Methods:Totally 96 children who undergoing elective surgery from July 2018 to October 2019 in Guangzhou Women and Children′s Medical Center were divided into experimental group ( n=48) and control group ( n=48). Two groups were admitted to the general preoperative waiting room for 60 minutes before the operation, and children in the experimental group recieved toy and cartoon video combination intervention, while children in the control group were subjected to routine nursing intervention. The children′s agitation was assessed by using Pediatric Anesthesia Emergence Delirium Scale (PAED) when children entered the post-anesthesia care unit (PACU), 10 minutes after in PACU and leave PACU. In addition, the vital signs such as blood pressure, heart rate, respiratory rate of the two groups were also recorded. Results:The emergence time and duration of PACU stay in the experimental group were (17.19±1.76) minutes and (22.47±2.36) minutes, significantly shortern than in the control group (18.36±2.19) minutes and (23.82±2.62) minutes, the difference was statistically significant ( t values were 2.760, 2.546, P<0.05). 10 minutes after in PACU and out of PACU, the PAED scores, systolic pressure, heart rate, respiratory rate was [7.56±1.86, 4.60±1.19, (108.12±10.19)mmHg, (102.72±8.55) mmHg, (112.91±6.10) times/minute, (106.39±6.75) times/minute, (18.87±1.98) times/minute, (17.49±1.68) times/minute], significantly lower than those in the control group [13.40±1.47, 6.71±2.21, (116.73±14.17)mmHg, (107.62±12.44) mmHg, (121.07±8.07) times/minute, (114.69±5.78) times/minute, (20.96±1.86) times/minute, (18.47±1.63) times/minute], the difference was statistically significant ( t values were 2.162-16.332, P<0.05). Conclusion:Toy and cartoon video combine-assisted admission can reduce the agitation and stable vital signs during recovery from general anesthesia in preschool children.
