Statistical Analysis on Gender Difference in Neural Activity for Spatial Ability Tasks

Gender differences are investigated from the viewpoint of cognitive neuroscience in the domain of spatial ability. Five task types of geometric problems are used for the collection of task-evoked fMRI data. Although there was no gender-difference in task performance, we found gender differences in neural activity. Some of the important gender differences that we found are 1) that there are far more joint neuro-activations among the brain regions, co-activations or reverse-activations, in males than in females, 2) that the two types of joint activations were nearly half and half in females while it was mostly co-activations in males, 3) that males tend to have more co-activations in the left hemisphere than expected while females tend to have more between-hemisphere co-activations than expected, and 4) that the left-right pairs of BA's are more highly associated than average for males while they are far less associated than average for females.

Prevalence of Metabolic Syndrome and Risk Factors Among Chinese Adults:Results from a Population-Based Study—Beijing,China,2017–2018

Summary What is already known about this topic?Metabolic syndrome(MetS)is one of the most easily available health indicative markers for cardiovascular diseases,and it has become a major public health problem worldwide due to increasing urbanization and aging populations.The prevalence of MetS increased dramatically in China,however,there are no records of MetS defined by the 2017 Chinese Diabetes Society for Beijing by far.What is added by this report?In this study,the data of 24,412 participants aged 18–74 years from a large population-based study in Beijing was collected.The overall prevalence of MetS among Beijing residents was 24.5%.The prevalence was 35.2%in males and 15.4%in females.What are the implications for public health practice?Effective public health strategies should target males,people with older age,lower education,higher body mass index,smokers,those who drink alcohol,those who are unemployed or retired,and those who live in rural areas on MetS prevention and control.

Cancer incidence varies significantly depending on Sasang constitution of Traditional Korean Medicine

OBJECTIVE: Sasang constitutional medicine is a component of Traditional Korean Medicine that stresses the hereditary makeup of disease incidences or therapeutic responses. This study investigated the relationship between the incidence of cancer and Sasang constitution classification. METHODS: Five hundred and one cancer patients were classified as having one of the four types of Sasang constitutions (Taeumin, Soumin, Soyangin, Taeyangin) using Questionnaire for Sasang Constitution Classification II, then compared with data from 1423 healthy subjects. RESULTS: The Sasang constitutional distribution for the cancer patients was significantly differentfrom that for healthy subjects: 22.8% vs 46.9% for Taeumin, 35.5% vs 24.0% for Soumin, and 41.7% vs 29.1% for Soyangin. Our results assumed that the lowest cancer incidence would be in Taeumin (around 2-fold in both sex) while the highest cancer incidence in Soumin males (2.8-fold) and Soyangin females (2.1-fold). CONCLUSION: This study identified a trend involving the frequency of cancer and the Sasang constitutional classification. We hope that this finding will provide new ideas for the study of cancer incidence and its preventive management.

Characteristics of Lung Function and Prevalence of Airflow Obstruction Among Individuals Aged 18–74 Years-Beijing,China,2017–2018

What is already known about this topic?Airflow obstruction is the hallmark of many chronic respiratory diseases and may indicate the potential for the development of other progressive diseases.There are currently no representative studies of lung function in Beijing.An up-to-date estimation of the characteristics of lung function and airflow obstruction is thus needed.What is added by this report?The estimated prevalence of airflow obstruction was 14.68%in Beijing,2017–2018.The values of vital capacity,forced vital capacity,and forced expiratory volume in the first second were 3.09 L,2.66 L,2.22 L,respectively.What are the implications for public health practice?Effective public health strategy for lung in Beijing should target older people,current or former smokers,and individuals who live in urban environments,have a low education level,exhibit a high smoking index,and/or have an abnormal body mass index.
