Association between peer relationship problems and childhood overweight/obesity

Aims:  To assess the association between peer relationship problems and childhood overweight and obesity.
Methods:  Data on 4718 preschool children were obtained at the obligatory school entry health examination in Bavaria. Parentally reported peer relationship problems ('normal', 'borderline' or 'abnormal') were assessed from the Strengths and Difficulties Questionnaire. Overweight and obesity were defined according to age- and gender-specific BMI cut-off points. Multivariate logistic regression analysis was performed to control potential confounders.
Results:  The prevalence of overweight and obesity was higher among children with 'borderline' or 'abnormal' peer relationship problems compared to 'normal' children. The association of 'abnormal' peer relationship problems was still significant in the final logistic regression model for girls [odds ratio (OR) for overweight 2.0; 95% confidence interval (CI): 1.4–3.0; OR for obesity 2.6; 95% CI: 1.3–5.0]. Among boys the adjusted odds ratio were lower and no longer significant.
Conclusion:  The significantly increased prevalence of overweight and obesity among preschool children with peer relationship problems could not be explained by confounding. It seems evident that there is a relevant co-morbidity of peer relationship problems and obesity in pre-school children pointing to the need of interventions focusing on both physical as well as psychosocial health.     

Infantile colic, prolonged crying and maternal postnatal depression

Aim:  To study if infant crying is associated with maternal postnatal depression.
Methods:  Data from 1015 mothers and their children participating in a prospective European multicentre study were analysed. Infantile colic and prolonged crying were defined as excessive crying as reported by the mothers 2 and 6 months after delivery, and at the same time the mothers completed the Edinburgh Postnatal Depression Scale (EPDS).
Results:  In cross-sectional analyses, infant crying was associated with high EPDS scores both 2 (OR: 4.4; 95% CI: 2.4–8.2) and 6 months postpartum (OR: 10.8; 95% CI: 4.3–26.9). More than one-third of the others of infants with prolonged crying had high EPDS scores 6 months postpartum. Longitudinal analyses showed that mothers of infants with colic had increased odds of having high EPDS scores 6 months after delivery even if crying had resolved (OR: 3.7; 95% CI: 1.4–10.1).
Conclusion: Both infantile colic and prolonged crying were associated with high maternal depression scores. Most noteworthy, infantile colic at 2 months of age was associated with high maternal depression scores
4 months later.     

肝再生研究中的热点问题

肝脏具有极强的再生能力,与其作为体内最重要的解毒器官并常被多种毒素损伤相适应.肝再生研究一直是再生医学研究领域的热点,其机制已得到深入阐明,但仍有一些热点问题尚存在广泛争议,例如,哪些因素决定了是肝细胞还是干细胞作为不同性质肝损伤后肝再生的主要细胞学基础;肝再生的启动因素有哪些;肝再生过程中肝功能是如何维持和代偿的;肝再生终止信号,以及肝再生结束后肝小叶如何进行重构.本文将就这些尚存争议或尚未阐明的问题进行阐述.     

Hypertension and stroke in Asia: A comprehensive review from HOPE Asia

Stroke is the primary cause of disability and vascular death worldwide, including Asia. Asian characteristics that differ from the West lead to higher stroke incidence. Stroke epidemiology studies in Asia have shown varying levels of mortality, incidence, prevalence, and burden of disease. Hypertension is the most prevalent risk factor found in Asia. Besides ethnicity that is associated with stroke incidence, both systolic blood pressure, diastolic blood pressure, and blood pressure variability are positively correlated with stroke incidence. Post‐stroke cognitive impairment is one of the sequelae that affect one‐third of stroke survivors and has become a significant public health concern that is often neglected despite its increasing prevalence. Therefore, it is very important to prevent recurrence by treating stroke optimally and effectively. Increasing awareness and treatment adherence to hypertension, the leading risk factor for stroke, became the main goal in several countries in Asia.
