If I tweet will you cite later? Follow-up on the effect of social media exposure on article downloads and citations.

Objectives: We previously reported that random assignment of scientific articles to a social media exposure intervention did not have an effect on article downloads and citations. In this paper, we investigate whether longer observation time after exposure to a social media intervention has altered the previously reported results.

Methods: For articles published in the International Journal of Public Health between December 2012 and December 2014, we updated article download and citation data for a minimum of 24-month follow-up.

Perinatal mental health care from the user and provider perspective: protocol for a qualitative study in Switzerland.

Background: Mental disorders in the perinatal period (PMD) can severely harm women and their children if not detected early and treated appropriately. Even though mental health care is covered by health insurance and is used widely by women in the perinatal period in Switzerland, it is not known if the care provided is meeting the needs of the patients and is efficient in the view of health care professionals. The aim of this study is to identify strengths, gaps and requirements for adequate mental health care in the perinatal period from the perspectives of patients and care providers for a wide range of relevant mental disorders.

Sexual and reproductive healthcare for women asylum seekers in Switzerland: a multi-method evaluation.

Background: Forced migration significantly endangers health. Women face numerous health risks, including sexual violence, lack of contraception, sexually transmitted disease, and adverse perinatal outcomes. Therefore, sexual and reproductive healthcare is a significant aspect of women asylum seekers' health.

Perinatal mental disorders in Switzerland: prevalence estimates and use of mental-health services.

Background: Perinatal mental disorders (PMDs) are the most common complication of pregnancy and the first postpartum year. Since PMD prevalence and use of mental-health services by perinatal women in Switzerland are unknown, we analysed existing health statistics.

Methods: We used statistics from a large health insurance company, hospitals and freelance midwives.

If I tweet will you cite? The effect of social media exposure of articles on downloads and citations.

Objectives: We sought to investigate whether exposing scientific papers to social media (SM) has an effect on article downloads and citations.

Methods: We randomized all International Journal of Public Health (IJPH) original articles published between December 2012 and December 2014 to SM exposure (blog post, Twitter and Facebook) or no exposure at three different time points after first online publication.

Results: 130 papers (SM exposure = 65, control = 65) were randomized.

An isochore transition zone in the NF1 gene region is a conserved landmark of chromosome structure and function.

The mammalian genome is organized as a mosaic of isochores, stretches of DNA with a distinct sequence composition. Isochores form the basis of the chromosomal banding pattern, which is tightly correlated with a number of structural and functional features. We have recently demonstrated that the transition from a GC-poor isochore to a GC-rich one in the NF1 gene region occurs within 5 kb and demarcates genomic regions with high and low recombination frequency.
