The prevalence of obstructive sleep apnoea in women with polycystic ovary syndrome: a systematic review and meta-analysis

Sleep and Breathing - Obesity is a common risk factor for polycystic ovary syndrome (PCOS) and obstructive sleep apnoea (OSA). Both PCOS and OSA are associated with increased risk of type 2...     

Living with severe aphasia: Tracking social exclusion

Background: Little is known about what happens to people with severe aphasia in the years after stroke when rehabilitation comes to an end, or about day‐to‐day life for this group.

Aims: This study aimed to track the day‐to‐day life and experiences of people with severe aphasia, and to document levels of social inclusion and exclusion as they occurred in mundane settings.

Methods and Procedures: Ethnography was chosen as the qualitative methodology most suitable for studying the experience of people with profoundly compromised language. 20 people who were judged to have severe aphasia following stroke agreed to be visited and observed three times in different domestic and care settings. The observer documented environments, protagonists, events, and interactions. Field notes were elaborated with personal, methodological, and interpretative notes. Written material (for example information leaflets) was also documented and described. Data were subject to thematic analysis.

Outcomes and Results: The study revealed how social exclusion is a common experience for this group, played out in a variety of ways in a range of domestic and care settings. Social exclusion occurs at infrastructural, interpersonal, and personal levels.

Conclusions: The study suggests that the social exclusion of people who struggle to communicate could be addressed through training, for professional and lay carers, that promotes support for communication; opportunity and access; respect and acknowledgment; and attention to the environment.     

Toxicological findings in suicides – frequency of antidepressant and antipsychotic substances

The role of psychoactive substances in the treatment of mental disorders and the risk of suicide are major public health issues. This cross-sectional study examined the prevalence of antidepressants and antipsychotics detected in toxicological screenings in suicides. Cases from the Institute of Legal Medicine of the Charité-University Medicine Berlin were reviewed over a 4-year-period. All cases (n = 477) with positive toxicology for antidepressants and antipsychotics in blood or organ tissue were included. Frequencies of the detected substances in non-suicide cases (n = 212; male n = 177, 55.2%; female n = 95, 52.5%) and suicide cases (n = 235; male n = 149, 63.4%; female n = 86, 36.6%) were examined. Tricyclic antidepressants (48.1%) were found most frequently in suicides, followed by atypical neuroleptics (37.0%), selective serotonin reuptake inhibitors (28.1%), typical neuroleptics (17.4%), tetracyclic antidepressants (16.2%) and other substances (8.9%). Alcohol was detected in 37.2% of suicides. The leading cause of death was drug poisoning (35.6%) followed by polytrauma (26.8%) and death by hanging (18.5%). A mental disorder (depression, schizophrenia, bipolar disorder, suicidality) was known in 22.9% of suicides. The most common location of death was the person’s own house (63.8%) followed by public places (28.1%) and hospitals (8.1%) The five most common substances in the suicide group were doxepin (20%) citalopram (15.3%), mirtazapine (14.9%), quetiapine (13.6%) and amitriptyline (12.3%). Toxicological findings from cross-sectional studies provide insight into how often certain types of antidepressants and antipsychotics are associated with suicide. A complementary approach is valuable for assessing the risk of suicide during medical treatment because the various available approaches (analysis of suicidal behavior/ideation, toxicity of drugs) each have strengths and limitations.     

The Mediating Effects of Alexithymia,Intolerance of Uncertainty,and Anxiety on the Relationship Between Sensory Processing Differences and Restricted and Repetitive Behaviours in Autistic Adults

Distress caused by sensory processing differences for autistic individuals may be reduced by repetitive behaviours (RRB), including repetitive motor (RMB) and insistence on sameness (ISB) behaviours. Intolerance of uncertainty (IU) and anxiety mediate the relationship between sensory processing and RRB in autistic children. We replicated this model in autistic adults, extending it to include alexithymia. Serial mediation, using data from 426 autistic adults, identified significant direct effects from sensory processing to RMB and ISB, and indirect effects through alexithymia-IU-anxiety for RMB, and IU alone, and alexithymia-IU for ISB. Different mechanisms may underpin RMB and ISB. Alexithymia alongside, IU and anxiety, should be considered when understanding the relationship between sensory processing and RRB, and when offering interventions to support autistic people.
