The need for psychiatric treatment in the general population: the Camberwell Needs for Care Survey
Background, This paper presents the first results of a two-stage psychiatric population survey, which uses a new method of directly evaluating needs for specific psychiatric treatment and the extent to which they have been met.Method, The sample was drawn at random from the population of an area of inner south London with high levels of deprivation. Seven hundred and sixty subjects aged 18-65 completed the GHQ-28. All those scoring > 5 and half of the rest were invited to take part in the second stage, comprising measures of mental state (SCAN), social role performance (SRPS), life events and difficulties (LEDS) and a Treatment Inventory. This information was used to rate the community version of the Needs for Care Assessment (NFCAS-C).Results, In all, 408 subjects were interviewed in the second stage. The weighted 1 month prevalence of hierarchically ordered ICD-10 psychiatric disorders was 9.8 %, the 1 year prevalence 12.3 %. The equivalent prevalences for depressive episode were 3.1 % and 5.3 % respectively, while those for anxiety states were both 2.8 %. At interview nearly 10% of the population were identified as having a need for the treatment of a psychiatric condition. This rose to 10.4 % if the whole of the preceding year was assessed. Less than half of all potentially meetable needs were met. There was only partial overlap between diagnosis and an adjudged need for treatment.Conclusion. A majority of people with mental health problems do not have proper treatment; given more resources and greater public and medical awareness, most could be treated by family doctors
Neural processing of criticism and positive comments from relatives in individuals with schizotypal personality traits
Objectives. High negative expressed emotion by family members towards schizophrenia patients increases the risk of subsequent relapse. The study aimed to determine whether individuals with high schizotypy (HS) and low schizotypy (LS) would differ in activation of brain areas involved in cognitive control when listening to relative criticism
Childhood bullying, paranoid thinking, and the misappraisal of social threat: trouble at school
Background:Experiences of bullying predict the development of paranoia in school-age adolescents. While many instances of psychotic phenomena are transitory, maintained victimization can lead to increasingly distressing paranoid thinking. Furthermore, paranoid thinkers perceive threat in neutral social stimuli and are vigilant for environmental risk.
Aims:The present paper investigated the association between different forms of bullying and paranoid thinking, and the extent to which school-age paranoid thinkers overestimate threat in interpersonal situations.
Methods: Two hundred and thirty participants, aged between eleven and fourteen, were recruited from one secondary school in the UK. Participants completed a series of questionnaires hosted on the Bristol Online Survey tool. All data were collected in a classroom setting in quiet and standardized conditions.
Results: A significant and positive relationship was found between experiences of bullying and paranoid thinking: greater severity of bullying predicted more distressing paranoid thinking. Further, paranoid thinking mediated the relationship between bullying and overestimation of threat in neutral social stimuli.
Conclusion: Exposure to bullying is associated with distressing paranoid thinking and subsequent misappraisal of threat. As paranoid thinkers experience real and overestimated threat, the phenomena may persist

Structure of the Extracellular Portion of CD46 Provides Insights into Its Interactions with Complement Proteins and Pathogens
The human membrane cofactor protein (MCP, CD46) is a central component of the innate immune system. CD46 protects autologous cells from complement attack by binding to complement proteins C3b and C4b and serving as a cofactor for their cleavage. Recent data show that CD46 also plays a role in mediating acquired immune responses, and in triggering autophagy. In addition to these physiologic functions, a significant number of pathogens, including select adenoviruses, measles virus, human herpes virus 6 (HHV-6), Streptococci, and Neisseria, use CD46 as a cell attachment receptor. We have determined the crystal structure of the extracellular region of CD46 in complex with the human adenovirus type 11 fiber knob. Extracellular CD46 comprises four short consensus repeats (SCR1-SCR4) that form an elongated structure resembling a hockey stick, with a long shaft and a short blade. Domains SCR1, SCR2 and SCR3 are arranged in a nearly linear fashion. Unexpectedly, however, the structure reveals a profound bend between domains SCR3 and SCR4, which has implications for the interactions with ligands as well as the orientation of the protein at the cell surface. This bend can be attributed to an insertion of five hydrophobic residues in a SCR3 surface loop. Residues in this loop have been implicated in interactions with complement, indicating that the bend participates in binding to C3b and C4b. The structure provides an accurate framework for mapping all known ligand binding sites onto the surface of CD46, thereby advancing an understanding of how CD46 acts as a receptor for pathogens and physiologic ligands of the immune system
