Vitamin D deficiency is common among otherwise healthy pregnant women and may have consequences for them as well as the early development and long-term health of their children. However, the importance of maternal vitamin D status has not been widely studied. The present study is divided into a societal experiment (1) and a case-cohort study (2): 1. The present study includes an in-depth examination of the influence of exposure to vitamin D early in life and during critical periods of growth for development of type 1 diabetes (T1D), type 2 diabetes, gestational diabetes, pre-eclampsia, obesity, asthma, arthritis, cancer, mental and cognitive disorders, congenital disorders, dental caries and bone fractures during child- and adulthood. The study is based on the fact that mandatory fortification of margarine with vitamin D, which initiated in 1937, was terminated in 1985. Apart from determining the influences of exposure prior to conception and during pre- and postnatal life, the investigators examined the importance of vitamin D exposure during specific seasons and trimesters, by comparing disease incidence among individuals born before and after the fortification. 2. Additionally, a validated method was used to determine neonatal vitamin D status using stored dried blood spots (DBS) from individuals who develop the aforementioned disease entities as adults and their time and gender-matched controls. Unparalleled, the study will help determine the effects of vitamin D exposure during critical periods in life. There are a sufficient number of individuals to verify any effects during different gestation phases and seasons of the year. The results, which will change our current understanding of the significance of vitamin D, will enable new research in related fields, including interventional research designed to assess supplementation needs for different subgroups of pregnant women. Also, other health outcomes can subsequently be studied to generate multiple new interdisciplinary health research opportunities involving vitamin D.

Rationale: Depression is a frequent complication after a stroke. In stroke guidelines several recommendations focus on early screening, and treatment off depression after stroke. Introducing clinical practice guidelines into routine daily practice however, is a difficult process. In order to make the recommendations applicable to clinical practice a toolkit was developed (the Post Stroke Depression-toolkit), which provides assessment tools for the early detection of depression after stroke, and a set of interventions in case of a positive screening for (risk on) depressive symptoms. Objective: to investigate the feasibility of the Post Stroke Depression-toolkit in daily practice. Study design: An explanatory mixed-methods, before-and-after study design. Study population: Nurses working on the neurological wards of one university hospital and two general hospitals in the Netherlands were included in the study. Additionally, data were obtained from patient charts.
Unfavorable outcomes (UO) are seen in 15 to 20% of patients with mild traumatic brain injury (mTBI). Early identification of patients at risk for UO is crucial for suitable management to be initiated, increasing their chances for a return to a normal life. The investigators previously developed a diagnostic tool enabling early identification (8 to 21 days after the injury) of patients likely to develop UO. In the present study, the investigators examined the value and beneficial effects of early multidimensional management (MM) on prognosis. The investigators used a diagnostic tool to classify 221 mTBI patients as UO (97) or FO (favorable outcome) (124). Patients whose initial risk factors point to UO are at risk of developing post-concussion syndrome (PCS). UO patients were randomized into 2 groups: a group that underwent MM (cognitive-behavioral rehabilitation) (34) and a group with no specific management (46). At 6 months, these 2 groups were compared and the impact of MM on outcome was assessed. Among patients initially classified as FO (101), 95% had FO at 6 months and only 5 had PCS as defined by DSM-IV classification. Of the UO patients who received MM, 94% had no PCS 6 months after injury, whereas 52% of the UO patients who did not receive MM had persistent PCS. The effect of MM on the recovery of patients at 6 months, once adjusted for the main confounding factors, was statistically significant (p<0.001). These results show that the initiation of MM after early identification of at-risk mTBI patients can considerably improves their prognosis.
Increased consumption of fast-food may be a contributing factor to the obesity epidemic. Posting calories on menus in fast-food restaurants is an important public health initiative and may help consumers to make lower calorie, healthier choices. This study will develop and test an intervention to improve the impact of calorie labeling policies. Further, the study will examine potential barriers to using posted calorie information
BACKGROUND: Despite the critical importance of breast milk for preterm and sick neonates, there is no consensus regarding the use of raw mother's own milk (MOM) in neonatal units. OBJECTIVES: This study aimed to describe the use of raw MOM in hospitalised neonates before day 7 (early use), and to investigate: (i) related factors, (ii) maternal satisfaction, and (iii) the association with breastfeeding continuation. METHODS: This prospective cohort included 516 neonates intended to be breastfed in 2 French neonatal units. Neonates receiving raw MOM before day 7 were compared to those who did not. The association between early use of MOM and breastfeeding continuation at hospital discharge, and up to 6 months later, was measured by logistic regression.
Bleeding is the most common complication associated with polypectomy of large pedunculated colonic polyp. Although several techniques have been developed to minimize bleeding, none of these methods has become the gold standard. To prevent post-polypectomy bleeding effectively, the investigators developed and attempted a new endoscopic technique for removal of large long-stalked pedunculated colonic polyps using band ligations. This study aims to evaluate the safety and efficacy of a novel technique using endoscopic band ligation for removal of long-stalked pedunculated colon polyps.
