Introduction Meteorological and environmental factors can affect people’s lives health, which is crucial among the older adults. However, it currently unclear how they specifically physical condition of adults people. Methods We collected analyzed basic examination indicators 41 people for two consecutive years (2021 2022), correlated them with meteorological factors. Partial correlation was also conducted to exclude unrelated as well. Results found that years, five (HB, WBC, HbAlc, CB, LDL-C) showed significant differences across population, had significantly different dynamic patterns six (air pressure, temperature, humidity, precipitation, wind speed, sunshine duration) seven air quality (NO2, SO2, PM10, O3-1h, O3-8h, CO, PM2.5). Discussion Our study has discovered first time between in normal examinations indicators, will provide guidance future development policies care healthy life

Abstract In mainland China, most infectious diseases occur once a year, except for scarlet fever, which has been steadily breaking out twice year in recent years. Over the years, recurrence of contagious disease characterized by distinctive red rash, focus attention. However, oscillatory mechanism fever remains unclear. This study aimed to uncover how meteorological factors contribute recrudescence China. The used longitudinal public dataset covering 31 provinces containing 14 years monthly infections, along with available local data. Power spectrum analysis was conducted on time series data, and correlation analyses were performed assess relationship between nature epidemics factors. We found that generally various timing these outbreaks’ peaks progressively from southern northern regions. Furthermore, we established an atlas shows oscillation Our findings indicated significant characteristics 50% each natural factor. presents detailed description temporal spatial changes first explores conditions their number infections. These could serve as valuable guide government prevention control measures epidemic.

Monitoring Sleep Quality Through Low α-Band Activity in the Prefrontal Cortex Using a Portable Electroencephalogram Device: Longitudinal Study (Preprint)

Опубликована: Окт. 4, 2024

The pursuit of sleep quality has become an important aspect people’s global quest for overall health. However, the objective neurobiological features corresponding to subjective perceptions remain poorly understood. Although previous studies have investigated relationship between electroencephalogram (EEG) and sleep, lack longitudinal follow-up raises doubts about reproducibility their findings. Currently, there is a gap in research regarding stable associations EEG data assessed through multiple collection sessions, which could help identify potential targets related quality. In this study, we used portable device collect resting-state prefrontal cortex over 3-month period from 42 participants (27 first month, 25 second 40 third month). Each participants’ was using Pittsburgh Sleep Quality Index (PSQI) estimate recent We found that significant consistent positive correlation low α band activity PSQI scores (<i>r</i>=0.45, <i>P</i>&lt;.001). More importantly, remained across all recordings (<i>P</i>&lt;.05), regardless whether considered same cohort or expanded sample size. Furthermore, discovered periodic component primarily contributed association with PSQI. These findings represent identification reliable target sessions. Our results provide solid foundation future applications devices monitoring screening disorders broad population.
