Negative bias in interpretation and facial expression recognition in late life depression: A case control study.

OBJECTIVES: While cognitive bias in younger adults with depression has been extensively researched, there have been relatively few investigations of the presence of cognitive bias in late life depression (LLD). This exploratory study aimed to ascertain whether negative cognitive bias exists across a range of cognitive domains in participants with LLD. METHODS/DESIGN: Participants were 19 patients with LLD and 19 matched non-depressed older adults. Participants completed standardised tests to assess bias in facial expression recognition, attention, recall of adjectives and interpretation. RESULTS: LLD participants were slower to identify surprised faces, and more likely to create negative statements in the interpretation task. There was no evidence of negative bias in memory or attention, but participants with LLD performed more poorly on the recall task. CONCLUSIONS: This study provides new evidence of negative bias in interpretation in LLD, but the findings are not consistent with a global cognitive bias Further work is needed to investigate cognitive bias in LLD. It may be that interventions which target negative interpretation biases, such as cognitive bias modification, could be helpful in treating LLD.

Peer support for junior doctors: a positive outcome of the COVID-19 pandemic?

The COVID-19 pandemic has imposed new, intense and, as yet, unquantifiable strain on the wellbeing of healthcare professionals. Similarities are seen internationally with regards to the uptake of psychological support offered to healthcare professionals during a pandemic. Junior doctors are in a unique position to offer and access peer support; this is an evidence-based strategy to promote psychological wellbeing of junior doctors through the COVID-19 pandemic and into the future. The development of peer support networks during the pandemic may lead to reduced physician burnout and improved patient care in the future. We discuss a peer support initiative to support medical trainees during the COVID-19 pandemic, discuss the barriers to the success of such schemes, and reflect on the value of grass-roots peer support initiatives.

Treatment for depression comorbid with dementia.

Depression is a common comorbidity in dementia. Randomised controlled studies of antidepressants do not show a significant improvement in depressive symptoms in patients with comorbid dementia and are known to lead to an increase in side effects. However, there are relatively few studies of depression in dementia, and drawing firm conclusions about the use of antidepressants is limited by the amount of data available. Furthermore, it is unclear whether data can be extrapolated from similar populations (eg, those with late-life depression) to inform pharmacotherapy in this patient group. Given the lack of effectiveness and risk of side effects associated with pharmacological treatments, psychological interventions may offer important therapeutic benefits. There is evidence for the effectiveness of individual psychological therapy, and further research will establish which psychological approach is the most effective. Some studies have shown an improvement in depressive symptoms using structured sleep hygiene programmes, exercise, arts interventions and music therapy. These studies are hampered by small data sets, and the benefits to individuals may not be well captured by standard outcome measures. At present, the best evidence for arts-based approaches is in music therapy. Depression with comorbid dementia responds well to electroconvulsive therapy and this is a useful treatment modality for those with severe or life-threatening depressive symptoms. Alternative neurostimulation techniques such as transcranial magnetic stimulation are not widely used at present and further research is needed before they can be a more widely used treatment modality.

Promoting early dementia diagnosis: a video designed by patients, for patients.

Early diagnosis of dementia allows people to access effective treatment and make advance decisions while they still have capacity. We aimed to encourage people to attend memory clinic, in order to boost rates of diagnosis. We created a patient information video about Oxford Health NHS Foundation Trust Memory Clinics, to inform and empower those awaiting assessment and to promote early diagnosis. Fourteen people (patients, carers, and staff) were approached prior to developing the video to ascertain their views on the themes the video should cover. The video consisted of unscripted interviews with patients, carers, and staff. We surveyed participants and new patients attending memory clinic to get feedback on the video and to assess patients' level of understanding and confidence about a memory assessment before and after watching the video. The video content was refined based on this feedback and a final version was produced. Patient feedback demonstrated that confidence and understanding increased after watching the video. Although this study is limited by its small sample size and lack of access to those with undiagnosed dementia, feedback suggested that the video empowered and reassured those awaiting assessment and could be used as a tool to reduce barriers to early diagnosis. Patients and carers involved in making the video found it a therapeutic activity in itself.

Driving and dementia: a clinical update for mental health professionals.

Most people with mild dementia can continue to drive, but dementia is progressive and many patients and clinicians will be faced with questions about driving safety in the course of their illness. Determining when this happens is a complex decision, with risks of personal and public safety needing to be weighed against individual patient benefits of driving in terms of autonomy, independence and well-being. Decisions need to make reference to cognitive abilities, as well as other factors including physical comorbidity, vision, mobility, insight and history of driving errors and accidents. Deciding to stop driving, or being required to stop driving is often difficult for patients to accept and can be a particularly problematic consequence of a dementia diagnosis. Legal frameworks help in decision-making but may not provide sufficient detail to advise individual patients. We review the current guidelines and evidence relating to driving and dementia to help clinicians answer questions about driving safety and to consider the full range of assessment tools available.

An evaluation of the use of olanzapine pamoate depot injection in seriously violent men with schizophrenia in a UK high-security hospital.

BACKGROUND: Oral olanzapine is a well-established treatment for patients suffering from schizophrenia. Advantages of depot olanzapine may include improved compliance. However, it is expensive, causes metabolic side effects, and carries a risk of postinjection syndrome. Clinical trials have shown olanzapine pamoate to be effective, but further work is needed in this area. This study was a retrospective service evaluation, carried out in a high-security hospital, where the majority of patients have complex, treatment resistant schizophrenia spectrum disorder and a very high propensity for violence. Compliance is a significant problem, both in the high-security setting and on discharge. There has been no previous published work that the authors are aware of evaluating the effects of olanzapine pamoate in this subgroup of patients. METHODS: The aim of the study was to evaluate the clinical efficacy of olanzapine pamoate, its effect on violence as well as its side effects, in a high-security setting for the first time. Anonymized patient records were used to identify the main outcome measure and clinical global improvement, and to ascertain secondary outcome measures which included seclusion hours, risk of violence and side effects. Metabolic parameters and number of incidents were also recorded. Eight patients were treated with olanzapine pamoate. RESULTS: Six showed an improvement in symptoms, with an associated decrease in violence and number of incidents. Four showed an associated decrease in seclusion hours. Two showed an increase in body mass index and two showed an increase in glucose. CONCLUSIONS: The findings of this study are important in showing that all patients who responded to olanzapine pamoate also showed a decrease in violent behaviour. The potential anti-aggression effects of olanzapine pamoate may represent a very promising area for further work. A depot antipsychotic medication that reduces violence could have significant implications for management of high-security patients.

Adverse incidents and patient safety - improving the learning experience of junior doctors.

The need to ensure patient safety in the National Health Service (NHS) is a national priority. However, it has long been recognised that a culture of blame impedes learning from previous adverse incidents. It is important to feedback the outcomes of investigations into incidents to NHS staff, but junior doctors have little knowledge of learning points from investigations into adverse incidents. Learning from past mistakes would improve practice and the level of care provided by junior doctors. A forum for learning from mistakes could also provide an opportunity to review past incidents in an open and supportive environment. This could, in turn, start to change the current culture of blame in the NHS and contribute to higher standards of patient safety in the future.

Context influences contour integration.

Much research over the last decade has examined how the brain links local activity within primary visual cortex to signal the presence of extended global structure. Here we bring together two themes within this area by addressing how the immediate context that features arise in influences how they are integrated into contours. Specifically, observers were required to detect and discriminate the shape of contours that were surrounded by elements with a fixed orientation offset compared to contour elements. By comparing performance with contours made of elements oriented either near parallel ("snakes") or near perpendicular ("ladders") to the contour orientation, we were able to isolate the effect of orientation contrast on observers' ability to perform our task with near-collinear contour structure. We report both substantial facilitation of contour integration in the presence of near-perpendicular surrounds and inhibition in the presence of near-parallel surrounds. These results are consistent with known orientation dependence of suppressive surround interactions in the primary visual cortex and suggest that the "rules of association" for contour integration must incorporate the influence of local orientation context. Specifically we show that our results are consistent with contour integration relying on an opponent-orientation energy response from a bank of first-stage oriented filters.
