BMCPsychiatry –Prevalence of problematic smartphone usage and associated mental health outcomes amongst children and young people: a systematic review, meta-analysis and GRADE of the evidence

自从引入广泛可用的智能手机以来，围绕智能手机使用与儿童和年轻人的心理健康下降之间可能关联的不确定性（CYP）。这是自2011年以来智能手机首次广泛使用以来，英国自我伤害率增加了68％。最近的研究提供了相互矛盾的结果，一些研究发现了其他可能没有的互动，这表明可能不是智能手机的使用或屏幕时间与精神健康不良，而是智能手机成瘾有关的时间。这是一个新术语的特征：有问题的智能手机使用（PSU）涵盖了几个行为成瘾的概念：宽容，戒断（电池消失时烦躁不安），全神贯注，忽视其他活动，主观丧失控制，尽管有证据表明，伤害。

By conducting a thorough systematic review and meta-analysis the authors of this paper found some harmful interactions between mental health and smartphone use. It showed the prevalence of PSU to range between 10%-30%, with females in the 17-19 year-old age group most likely to exhibit symptoms of PSU. The study also identified a significant association between PSU and depression, anxiety, insomnia, stress and poor education attainment as well as identifying similarities between PSU and substance abuse disorders. Like alcohol, smartphone use is socially acceptable and widely available posing a different and arguably more pressing public health problem than substances of abuse. With 1 in 4 CYP demonstrating problematic smartphone use and patterns of behavioral addiction that mirror substance use addiction, urgent policy reform is required to prevent the possible long term and widespread impact on current and future generations’ mental health and well-being.

BMC癌 -有症状女性的卵巢癌初步评估和调查的差异：国际准则的系统评价

With an increasing number of tests available for the diagnosis of women with symptomatic ovarian cancer and 200,000 women per year being diagnosed with ovarian cancer globally, it has become increasingly important to understand and evaluate differences in policy and guidance for testing strategy across systems. By conducting a systematic review the authors of this manuscript identified that most women diagnosed with ovarian cancer are not diagnosed until the onset of clinical symptoms. Their results also identified significant differences between international guidelines for identification of ovarian cancer. Since differences persist not only in the clinical features suggested to trigger the suspicion of ovarian cancer but also in the initial examinations and investigations these guidelines advocate.

已知已经存在明显的积极相关性，在国家生存和初级保健从业者准备调查或转介出可能出现卵巢癌症状的妇女之间存在，国际准则的差异可能对卵巢癌诊断和生存的及时性产生影响。该研究发现，执行的测试的复杂性与进行初步评估的临床医生的专业之间存在显着相关性，这表明在英国，爱尔兰，澳大利亚和斯堪的纳维亚半岛等国家中，全科医生（GPS）是对更多专业推荐人的守门人，可用于卵巢癌的测试更加有限，可能会增加诊断时间。作者得出的结论是，建议的文件和准则，特别是与医疗保健系统（国家或私人）相关的文件，以显着影响及时的卵巢癌诊断的可能性。

BMC公共卫生 -Describing associations between child maltreatment frequency and the frequency and timing of subsequent delinquent or criminal behaviors across development: variation by sex, sexual orientation, and race

Child maltreatment has been linked to lower health, education, and income later in life, and is associated with increased engagement in delinquent or criminal behaviors. With 9 out of every 1000 children in the United States experiencing maltreatment resulting in their involvement in the child welfare system, this study aimed to explore trajectories of behavior from adolescence into early adulthood and how maltreatment during childhood may act as a predictor. Using a sample of more than 10,000 U.S. adolescents, the authors aimed to test the effect of maltreatment on behavior and the associations between them with special focus on the effect of physical, sexual, emotional and psychological abuse, exploitation or neglect perpetrated by individuals in positions of power.

The study finds that individuals exposed to maltreatment had higher levels of violent offending, progressively increasing with continued exposure to maltreatment frequency. It also found a positive relationship between individuals identifying as LGBQ (Lesbian, Gay, Bisexual, or Queer) and the level of non-violent offending frequency as compared with non-LGBQ individuals. In addition, the study identified that the relationship between maltreatment and predicted non-violent offending is stronger for males compared to females, with teenage maltreated males having the greatest predicted non-violent offense frequency. The authors conclude that better understanding the differences in experiences between males and females may be particularly important as increasing numbers of females become engaged in the juvenile justice system. Further, they state an increased need to teach males, in particular, how understanding and identifying stress responses could decrease the need for externalizing responses.

BMC怀孕和分娩 -怀孕和与新生儿不良结局的妊娠中自我报告的精神障碍的患病率：基于人群的横断面研究

With 3.7 deaths per 100,000 pregnancies resulting from mental-health related causes, mental disorders are one of the most common causes of mortality and morbidity for women during the perinatal period, with 101 women dying by suicide in the UK and Ireland between 2009 and 2013 alone. This represents one in seven of all maternal deaths. However, whilst maternal suicide is the highest cause of mortality in perinatal women, it is not the only mental-health related outcome, with perinatal depression, anxiety and psychosis being other serious effects of mental disorders during the perinatal period. Previous studies have found that women with a history of severe mental illness commonly experienced a relapse or deterioration of their condition during the perinatal period, with 43% of women experiencing a relapse of a major depressive disorder and up to 50% experiencing a major bipolar disorder. Other examples of commonly observed relapses include psychosis, schizophrenia, anxiety disorders, obsessive-compulsive disorder and eating disorders. These are also further confounded by substance misuse or intimate partner violence. Declining mental health of pregnant women has also been associated with adverse neonatal outcomes, finding strong associations between mothers with depression and the lower preterm birth of the neonate. Similar interactions are observed in women with maternal schizophrenia where the child is more likely to be born with congenital abnormalities, identifying serious impacts of maternal mental health on pregnancy outcomes. This study highlighted that out of a cohort of over 140,000 pregnancies, one fifth reported a history of a mental disorder, of which 80% of women had no access to specialist perinatal mental health services. This paper emphasizes the critical importance of routine enquiry regarding the psychiatric history of women presenting to maternal services.
