In November 2009 there were reviews of studies on the prediction of age-specific dosing of antipsychotics, mental health informatics applications and infrastructures, consultation-liaison services and an investigation of a relationship between the metabolic syndrome and depression. There were some very good blogs which were reviewed including PsychBrownBag which provides analysis of psychology research studies and clinical questions and FABLE, which investigates the relationship between the body, emotions and the literature. There were also media reviews of programs/podcasts on language and the relationship between genetics and late-life depression. There were several book reviews including those on the nature of science and the impact of technology on culture. In the news there was a report commissioned by the UK government highlighting risks associated with antipsychotic use in dementia and giving recommendations to which there were several institutional and organisational responses. Other developments included a study suggesting that there may be optimum levels of Beta-Amyloid for memory functioning, the construction of an 11.7 Tesla MRI scanner in France, the estimate fromone large survey that 1/4 of all psychotropic medications prescribed in the USA were by psychiatrists, a Norwegian study showing marked reduction in separation of couples when using ‘client feedback’ therapy and a recent discussion about possible changes to the Asperger syndrome diagnosis in DSM-V.

News in Brief
An independent report by Professor Sube Banerjee, commissioned and funded by the Department of Health on the use of antipsychotics in dementia has been published (freely available here). Professor Banerjee has considered the evidence base including systematic reviews and meta-analyses regarding the use of antipsychotics in dementia and the report contains an estimate of the national morbidity and mortality associated with the use of antipsychotics in dementia. The report recognises the need for antipsychotics in certain situations and goes on to make a series of recommendations which focus in particular on clinical governance, recommendations which should lead to an improvement in the quality of care. The government have produced their response to this document (freely available here) and support these recommendations indicating that a national audit of antipsychotic use in dementia will be undertaken initially at six-months and then annually for at least three years and that the National Clinical Director for Dementia will take on a leadership role in this area. The Royal College of Psychiatrists has welcomed the report and responded here emphasising the need for input of specialist older adult mental health services. The response of the Alzheimer’s Society who have also welcomed the report is here. NHS choices have coverage of the report here.
A study in Nature Neuroscience suggests that Amyloid Beta is integral to memory function and that deviation from optimal levels is likely to lead to pathology. This in turn would suggest that removing Amyloid Beta from the plaque may not be a successful strategy in Alzheimer’s Disease if this optimal level is not addressed. However this discussion is taking place around cellular mechanisms and it will be useful to see how these predictions tie in with the relevant clinical trials. A suggestion has been made that a precursor to Nerve Growth Factor may be involved in the pathogenesis of Alzheimer’s Disease (AD) on the basis of a significant increase in the levels of the precursor in AD post-mortem samples and findings in a murine model. Stroke is related to dementia in a number of ways and modifying stroke risk factors can reduce the risk of dementia. Thus a prospective study (n=3298) with a follow-up period of 9 years showed that moderate or heavy exercise was asssociated with a significantly reduced risk of developing stroke. Thus the risk was 2.7% in those with moderate-to-heavy exercise and 4.6% in those with no exercise. A potentially very useful study used the Alzheimer’s Disease Neuroimaging Initiative dataset to develop a method of analysing MRI data which involves two scans and a focus on loss of tissue in the Entorhinal Cortex and it will be intereresting to see the results of further research in this area. A 32-year prospective study – the Prospective Population Study of Women in Gothenburg found an association between central adiposity in middle age and prevalence of subsequent dementia. They did not find the same relationship between BMI and subsequent dementia but the central adiposity was associated with an approximate doubling of the prevalence of subsequent dementia.
There is a recent study which provides evidence of a relatively small difference in the rate of decline of memory in those with Alzheimer’s Disease with or without diabetes. Those with diabetes had a slower rate of decline (although the effect size was relatively small) and it will be interesting to see further replication studies in this area. Alz Forum have got coverage of the recent Clinical Trials in Alzheimer’s Disease conference in Las Vegas here. They look at the Wisconsin Registry for Alzheimer’s Prevention study, the Memory Capacity Test and research on the CogState test amongst others. There is coverage here of a 20-year longitudinal study published in Neurology which identified associations with the development of mild cognitive impairment and it will be interesting to see how these findings inform further research in this area. This article looks at another study published in Neurology this time on Frontotemporal Dementia (FTD) and finding that 42% of subjects had a family history on the basis of a related outcome measure (see here for further information). There is coverage of the recent Society of Neuroscience conference in Chicago over at the Alzforum and this featured a number of presentations on Alzheimer’s Disease. A recent study looking at falls in older adults found associations with a number of medications. The researchers in another study looking at falls in the elderly (the MOBILIZE study, n=729) found that those with chronic pain were significantly more likely to fall than their counterparts without.
A neuroimaging study (n=88) compared people with Asperger Syndrome and Autism with controls and found a significant difference between the Asperger and Autism groups in terms of structural MRI findings with the latter group having increased grey matter volume in the frontal and temporal lobes (Toal et al, 2009). However it will be interesting to see this data be included in a meta-analysis with other similar studies as well as to see the findings of larger replication studies. This study is timely given the recent discussion about dropping the diagnosis of Asperger Syndrome (see below). There is a discussion here of some of the recent genetic evidence of similarities between Schizophrenia and Autism in terms of analysis of copy number variants. The possible role of a form of interneuron known as the gliaform cell in psychosis is discussed in this article.
Articles included a systematic review of RCT’s and observational studies of oral versus long acting injectable (LAI) depots, a review of psychopharmacology and side-effects of LAI’s, a systematic review of second-generation LAI’s and a review of UK prescribing practice amongst many other articles. The Schizophrenia Research Forum have coverage of a recent murine study showing an association between mutations in the dysregulin gene (which has been associated with schizophrenia in genome wide association studies) and the function of fast-spiking interneurons. The 26th Annual Pittsburgh Schizophrenia Conference took place on November 13th 2009.
An American study showed that just under half of the 3 to 6 year olds in the study were concerned about becoming obese and one-third wanted to change an aspect of their appearance. Another American study (due to be published next year and with n=184) contrasted brief motivational interviewing with a control intervention (warning about the hazards of drinking and driving) in drink-driving recidivists was associated with a 30% reduction in repeat offences. Using data from the National Epidemiological Survey on Alcohol and Related Conditions, an american study involving data on 43,000 people, older adults (over the age of 60 in this study) with alcohol dependence consumed an average of 40 alcoholic drinks per week compared to ‘between 25 and 35 drinks a week’ in the younger group.
The National Institute of Clinical Excellence has released guidance on the treatment of depression in people with chronic health problems – the quick reference guide is here. A small case series which looked at deep brain stimulation for severe depression provided some evidence of efficacy although given the sample size, it will be interesting to see the outcome of a relevant systematic review or meta-analysis which incorporates this data. An american study is looking at whether PTSD can be predicted by incorporating a number of biological markers. In a study (n=109) of people with depression and controls there was found to be an association between depression and overestimated retrospective recall of somatic symptoms and this is just one of many ways in which depression and physical illness may have complex interactions. There was a recent study which used a large number of outcome measures which investigated collectivist versus individualistic cultures and the authors suggest that the former are associated with a lower genetic predisposition to depression. However it is important to note that there are cultural differences in the use of diagnostic classifications (e.g. see this review).
An 11.7T MRI scanner is being developed in France through a pan-European partnership and is due to begin operating in 2012. In a press release from the company that undertook the researhc, in conjunction with university researchers, the gene product for the gene Rps23r1 was associated with a reduction in two Alzheimer’s Disease related proteins amyloid beta and tau in a murine model. The researchers in a study in Neuron found an association between modifications of cortical theta oscillations and the perception of intact sounds when presented with fragmentary sounds. Thus the implication is that there is an EEG correlate of auditory illusions. Another study offers preliminary insights into the potential role of the delta waves generated in the hippocampus and the authors hypothesise on the basis of their results that the frequency of the delta waves code information about the type of processing that should take place in different regions – processing about the past or present. There is preliminary evidence that inflammation in the hippocampus may be associated with schizophrenia although it will be useful to see the results of further studies in this area.
The researchers in an american study covered here found that of 472 million prescriptions for psychotropic medications prescribed between August 2006 and July 2007, only 1/4 were prescribed by psychiatrists. Virtualised desktops save time in booting up the computer and in this article a proprietary system using virtualised desktops was suggested to save clinicians 30 minutes on average each day. The National Institute of Clinical Excellence has released guidance on mental wellbeing at work. The document has a wide audience including members of the public (where applicable in the UK) and complements previous NICE guidance in the workplace. The quick reference guide contains 5 recommendations relating to strategic/coordinated approaches to mental wellbeing, assessment of opportunities for wellbeing of employees, flexible working, the role of line managers and supporting micro, small and medium-sized businesses. This has been widely reported with a number of articles looking at how these recommendations might impact on health services themselves (see here, here and here). This comes at the same time as a report by the Chartered Institute of Personnel and Development (CIPD) which produced findings from a survey of 2000 employees which included results relating to mental health (covered here). Technology review have a collection of images about representing 100 years of visualising the brain. A comedian has been invited to contribute a humorous perspective to a production on mental health by a primary care trust. There is a clip of the performance in the article and the argument is that the comedy can help to overcome stigma through education. You can see the responses of members of the audience in the clip.
A study of babbling in babies (covered here) found evidence that after only an hour’s exposure to a new language, the baby’s babbling with the speaker of that new language differed from that with speakers of the native language. A recent study involved 205 Norwegian couples and used ‘client feedback’ therapy during problematic episodes in their relationship. At 6-months after the last session, the researchers reported a 50% reduction in divorce or separation rates compared to those who did not receive this intervention. The approach is described as patient focused research (the Research Advocacy Network has more information on this).
The Lean Healthcare Academy recently had an awards ceremony and a hospital which implemented the Productive Ward was the recipient of an award. The Productive Ward and related Productive Series involve a systematic process to enable improvements in outcome measures such as efficiency (see review here). It is interesting to see how American and Japanese culture and technology is being used to improve care for patients in the NHS in an ever more connected world. The Productive Ward series is covered at the National Institute for Technology here. The series also includes approaches to improve outcomes in community care as well as other types of service.
The new buzz word in this area is ‘primate archaeology’ which is an attempt to integrate a number of areas including primatology, anthropology and psychology. This article summarises this new ‘movement’ and looks at some very interesting research into the use of stone tools by chimpanzees in what is being described as a parallel with the advent of the stone age in humans. Dr Shock has a link to a video showing that squirrels work together to recall where food is located in the environment. The combination of social cooperation and memory abilities displayed here may be important in understanding similar abilities in primates including humans. Recent evidence suggests that the Sahara may have experienced wet periods roughly 120,000 years ago and 50,000 years ago and that this may have facilitated the migration of early humans across the Sahara. There is an article at Live Science on the decreasing size of the human brain over the last 10,000 years which asks the intriguing question ‘is our evolution accelerating?’. The FOX-P2 gene product in chimpanzees was found to behave differently to the gene product in humans in a recent study which might contribute to an explanation for the absence of spoken language in chimpanzees.
There is a recent statement from a geneticist Professor Paabo that Neanderthals and humans interbred according to analysis of the Neanderthal genome (see also here) and it will be interesting to see further evidence when it is published. However the remaining question is whether or not the Neanderthals contributed to the modern human gene pool which is a separate although related question which may be answered with the completion of the sequencing of the Neanderthal genome. If this were so, it would have many implications. Another paper on genetic material – heterochromatin may in the future help to answer the question of whether the offspring would be sterile.
A twitter campaign was started to petition for the inclusion of Depressive Personality Disorder in DSM-V. There was discussion recently of the diagnosis of Asperger syndrome being dropped from the next edition of the DSM and this will mean an expansion of the autism diagnostic category. This was originally discussed in a New York Times article (which requires (free) registration). The article features an interview with Dr Catherine Lord, who is one of 13 members of the working group on autism and neurodevelopmental disorders. The group are considering a number of amendments to the autism diagnosis including the addition of comorbidity that have been associated with the condition including disorders of attention and anxiety. However the suggestion regarding Asperger syndrome has not yet been ratified by the group. There have been a number of responses in the media. This article contains interviews with a doctor who runs a clinic, a parent of a child with Asperger’s syndrome and the president of a non-profit organisation for raising awareness of the condition. There is some information on the DSM-V process here. There is further discussion of the DSM-V Asperger syndrome diagnosis on the left-brain, right-brain blog and at the time of writing there are 87 comments, testimony to the interest this discussion is creating. Dr Grohol also covers this over at Psychcentral. Professor Simon Baron-Cohen has argued against the removal of the Asperger Syndrome label in this New York Times article. Dr Anestis offers his views on this article and Baron-Cohen responds in this blog post.
At the ISCI healthcare blog there is an article looking at some of the ways in which twitter is being used in healthcare. MindHacks has another news roundup in ‘Spike Activity‘ and included is a link to an interview with Terry Pratchett about Alzheimer’s Disease. The ‘Heal My PTSD‘ blog contains a round-up of Post-Traumatic Stress Disorder (PTSD) news including the use of a virtual reality environment for re-experiencing trauma as part of a therapeutic intervention. This BBC article looks at some of the ways web 2.0 technology is being used by the research community. Patients in the USA are beginning to carry their healthcare information around with them in iPhone apps as reported in this article. The Science in the Open blog has an article looking at how an open collobarative framework might change science (Science 2.0) with the possibility of the science being separated into data acquisition, data analysis and dissemination of results. An article here looks at recent research which counters the argument that use of the internet has casued people to become more isolated. They cite research which suggests that people are not more isolated than in 1985 and elsewhere that people who use the web regularly are more likely to participate in social activities such as meeting up with friends . See here for more information.
In the BJPsych there is an interesting article by Professor Michael First who writes about the potential for harmonisation of DSM-V and ICD-11 which is a widely discussed topic (First, 2009). There are a number of points of interest in the article and he notes that there are investigators involved with revisions of both systems which should help to contribute to attempts to harmonise both systems. The discussions around these systems will no doubt increase*.
In a small study, participants were observed using search engines. The researchers concluded that search strategies were influenced by the learning styles of the participants and that participants often used search engines to confirm then own recall of a subject. A recent MyPublicServices event was held to discuss ways in which social media might impact on public services. It was suggested at the conference and reported in this article, that social media may impact on public health service delivery as it has done in many other sectors and that a constructive approach to using social media in th9s area could be adopted. One research study into viral marketing campaigns focused on the characteristics of e-mavens – people who spend a lot of time online**. E-maven’s characteristics were identified and those that were more likely to forward viral material onto others scored more highly on measures of individualism and altruism. The FDA has convened the social media hearings to examine the issue of regulation of pharmaceutical companies use of social media and this has been widely discussed in the mainstream media, the blogosphere and the twittersphere. An article here has lots of discussion in the comments section.
This BBC article looks at Google Wave and includes a interview with the founders and some examples of use. Google wave is a collaborative tool that is described as facilitating the linking of ideas and data, allowing for instance data to be inserted relatively easily by multiple authors into a collaborative document. There is further coverage of Google Wave applications in this article which contains an embedded video and lists uses including research where Google Wave has provided benefits. The ICS healthcare blog has an article on how the doctor-patient relationship might be changing due to the influence of factors such as health 2.0. Ted Eytan in his blog has coverage of a study published in May that involved a focus group of patients who use the internet. The findings included an expressed interest by the people in the study to have access to their medical records. ‘360 digital influence’ discuss trends in the use of social media by doctors here including a look at research in this area.
Dr Shock links to an educational video about the redesign of the PubMed interface which is useful for those undertaking literature reviews, database searches and related activities. Sandy Gautam has started a new blog – My 2 Brains and in this post he reflects on twitter including a look at how it relates to the expression of self. MindHacks has his weekly round up here. Mind Hacks has another episode of Spike Activity where he reviews the news including a link to a study showing an association between creativity and horizontal eye movements, adding to previous research suggesting an association with recall of information.There is an article here about web-based healthcare. The Journal Cell has an article on twitter and at least one of the scientists quoted in the article found that it was useful in keeping up to date with developments in their field.
The ‘Heal My PTSD’ blog has a news round-up which includes the use of telemedicine for PTSD. John Grohol has an article at PsychCentral on how ‘first impressions count’ online and argues that these impressions are formed through inspection of photographs and he also reports on a study looking at Facebook use which is due for publication next year. There is a presentation available here on how web 2.0 might affect education. The Gov 2.0 conference is due to take place online on December 10th 2009. Biomedcentral has an open-access article on a ‘database of everything’. A German petition is currently underway requesting that all publicly funded studies should be made available through open-access articles. The ZZoot blog has coverage of a recent workshop on the future of the semantic web for scientific communication. In this article there is a look at an organisation which matches researchers with research participants.
The Google Wave tool which has been recently rolled out enables live collaboration using a number of tools and in this article Leah Betancourt discusses some of the ways this is being used in the creation, dissemination and discussion of news. Conventional methods for disseminating scientific/clinical information including conferences, journals and books are now in the process of being transformed by such tools. Another development which has the potential to have a profound impact on society, Government 2.0 was discussed at a recent conference. The idea here is that citizens can both engage with and contribute to the decision-making process of government. As an example this may impact on the way in which different segments of society are represented and this in turn could impact on health and illness on a number of levels. The American Association for the Advancement of Science has set up an expert lab to help government engage with citizens using technology and enabling them to tap into ‘crowd expertise’. There is a video on the expert lab here. In an american survey by Manhattan Research, 39% of doctors stated that they had communicated with patients online although the insurance-based nature of the healthcare system may influence such relationships. An article here looks at how doctors are using technologies such as twitter and the iPhone in their practice. Meanwhile the Danish Government is intending to go paperless by 2010.
