BMC Psychology–悲伤的父母以及他们需要知道的婴儿时需要知道什么

Around 2.6 million babies a year are stillborn. Although it’s always devastating to lose a baby, parents grieving for a stillborn child are more likely to experience depression and post-traumatic stress than those when the child had been born alive. There is considerable stigma, social shame and marginalization associated with parental grief for a stillborn child with the result that it has attracted little attention by health care providers, resulting in inadequate support.

Farrales等。最近，进行了一项定性的参与研究研究，以探索亲人的父母在孩子中与卫生保健提供者互动时的经历。回顾表明，母亲和父亲都需要从其医疗保健提供者那里确认婴儿是不可替代的婴儿个人本身就认识到他们是悲伤的父母，认识到了多胎的创伤，并认识到父母将继续感到丧命，并且他们需要支持。

BMC医学研究方法–CoCites: a citation-based search method for scientific literature

CoCites由Janssens等人开发。在Emory University。与许多其他用于搜索科学文献的工具不同，Cocites使用引用而不是关键字。它被设计为比传统的基于关键字的方法更有效，并假设用户在所选的研究领域中至少知道一篇高度相关的文章，从而删除了以前被引用的所有文章。

洋中le describes the results of using CoCites to reproduce the literature searches of a number of published systematic reviews and meta-analyses; these showed that CoCites retrieved a median of 75% of the articles that were included in the original reviews.

BMC肌肉骨骼疾病–Playing sport while injured might cause arthritis

受伤时，参加运动的人通常会面临困境。他们应该继续比赛还是停止。到目前为止，尚未研究对关节健康和与健康相关的生活质量（HRQOL）受伤时进行运动的含义。考虑到这一点，Bullock等人。对受伤时的比赛，HRQOL，骨关节炎和持续的关节疼痛之间的关系进行了研究，比较了精英和休闲板球运动员的发现。该研究涉及要求参加描述其历史的问卷of playing sport while injured and details on any diagnosed osteoarthritis and/or persistent joint pain. It was found that, indeed, cricketers who played injured had their HRQoL adversely affected and were at increased risk of osteoarthritis and joint pain. The authors conclude that the long-term impact of playing while injured should be considered when advising athletes on their ability to compete following an injury.

BMC Pediatrics–How many words are Australian children hearing in their first year of life?

There is evidence to suggest that parents from more socioeconomically disadvantaged backgrounds interact verbally with their children less than parents from more advantaged background, resulting in what has been coined “the 30 million-word gap”. Brushe et al. decided to explore this further, investigating the number of worlds children hear in their first year of life and whether this is influenced by the level of education attained by the mother. The five year study involved grouping the mothers into high or low education groups and then collecting data from audio-recordings when the children were 6 months old and again when they were a year old. The number of words spoken by the mothers when they were talking to their children were counted using the Language Environment Analysis software. Results showed that there was a large variation of words spoken by the mother within each education group, but no meaningful differences between the different educational groups. This suggests that a word gap associated with the level of education attained by the mother is not apparent in the first year of a child’s life.
