In need of psychiatric help--leave a message after the beep

Every day, a substantial proportion of the general population experiences the distressing and frightening signs of an upcoming psychiatric illness. The consequences can be enormous because severe psychiatric disorders typically cause the loss of the ability to work and often mean a long-term burden for both the patients and their families. Even though most developed countries have an exceptionally high density of general practitioners and psychiatrists in private practice, getting a mental health appointment and seeing a doctor is often very difficult for patients with acute psychiatric symptoms. This study aimed at quantifying the time delay involved in seeking medical attendance when psychiatric disorders begin to develop.

Help-seeking pathways in early psychosis

INTRODUCTION: Understanding the help-seeking pathways of patients with a putative risk of developing psychosis helps improving development of specialised care services. This study aimed at obtaining information about: type of health professionals contacted by patients at putative risk for psychosis on their help-seeking pathways; number of contacts; type of symptoms leading to contacts with health professionals; interval between initial contact and referral to a specialised outpatient service. METHOD: The help-seeking pathways were assessed as part of a prospective study in 104 patients with suspected at-risk states for psychosis. RESULTS: The mean number of contacts prior to referral was 2.38. Patients with psychotic symptoms more often contacted mental health professionals, whereas patients with insidious and more unspecific features more frequently contacted general practitioners (GPs). CONCLUSIONS: GPs have been found to under-identify the insidious features of emerging psychosis (Simon et al. (2005) Br J Psychiatry 187:274-281). The fact that they were most often contacted by patients with exactly these features calls for focussed and specialised help for primary care physicians. Thus, delays along the help-seeking pathways may be shortened. This may be of particular relevance for patients with the deficit syndrome of schizophrenia.

CD4+ T cell help improves CD8+ T cell memory by retained CD27 expression

CD4+ T cell help during the priming of CD8+ T lymphocytes imprints the capacity for optimal secondary expansion upon re-encounter with antigen. Helped memory CD8+ T cells rapidly expand in response to a secondary antigen exposure, even in the absence of T cell help and, are most efficient in protection against a re-infection. In contrast, helpless memory CTL can mediate effector function, but secondary expansion is reduced. How CD4+ T cells instruct CD8+ memory T cells during priming to undergo efficient secondary expansion has not been resolved in detail. Here, we show that memory CTL after infection with lymphocytic choriomeningitis virus are CD27(high) whereas memory CTL primed in the absence of CD4+ T cell have a reduced expression of CD27. Helpless memory CTL produced low amounts of IL-2 and did not efficiently expand after restimulation with peptide in vitro. Blocking experiments with monoclonal antibodies and the use of CD27(-/-) memory CTL revealed that CD27 ligation during restimulation increased autocrine IL-2 production and secondary expansion. Therefore, regulating CD27 expression on memory CTL is a novel mechanism how CD4+ T cells control CTL memory.

Self-help extension: Farmer-to-farmer extension

As staff and mobility cost have the lion share of the costs of extension work, there have been many alternatives to assign farmers the job of facilitators, trainers and advisors. The arguments behind are that they are geopraphically closer to the clients, but also mentally and culturally, because they are members of the client group themselves, speak their language and share their experience and daily life. The article starts with the origins of the larger movement in Latin-America, and then discusses potentials and limitations, and finally experience from elsewhere.

Help from under ground: soil biota facilitate knotweed invasion

Soil biota can be important drivers of plant community structure. Depending on the balance between antagonistic and mutualistic interactions, they can limit or promote the success of plant species. This is particularly important in the context of exotic plant invasions where soil biota can either increase the biotic resistance of habitats, or they can shift the balance between exotic and native plants towards the exotics and thereby greatly contribute to their dominance. Here, we explored the role of soil biota in the invasion success of exotic knotweed (Fallopia × bohemica), one of the world's most noxious invasive plants. We created artificial native plant communities that were experimentally invaded by knotweed, using a range of substrates where we manipulated different fractions of soil biota. We found that invasive knotweed benefited more from the overall presence of soil biota than any of the six native species. In particular the presence of the full natural soil biota strongly shifted the competitive balance in favor of knotweed. Soil biota promoted both regeneration and growth of the invader, which suggests that soil organisms may be important both in the early establishment of knotweed and possibly its later dominance of native communities. Addition of activated carbon to the soil made the advantage of knotweed disappear, which suggests that the mechanisms underlying the positive soil biota effects are chemically mediated. Our study demonstrates that soil organisms play a key role in the invasion success of exotic knotweed.

Internet-Based Guided Self-Help for Several Anxiety Disorders: A Randomized Controlled Trial Comparing a Tailored With a Standardized Disorder-Specific Approach

Internet-delivered self-help with minimal therapist guidance has shown promising results for a number of diagnoses. Most of the evidence comes from studies evaluating standardized disorder-specific treatments. A recent development in the field includes transdiagnostic and tailored Internet-based treatments that address comorbid symptoms and a broader range of patients. This study evaluated an Internet-based tailored guided self-help treatment, which targeted symptoms of social anxiety disorder, panic disorder with or without agoraphobia, and generalized anxiety disorder. The tailored treatment was compared both with standardized disorder-specific Internet-based treatment and with a wait-list control group. Both active treatment conditions were based on cognitive-behavioral therapy and lasted for 8 weeks. A total of 132 individuals meeting diagnostic criteria for at least one of the anxiety disorders were randomly assigned to 1 of the 3 conditions. Both treatment groups showed significant symptom reductions as compared with the wait-list control group on primary disorder-unspecific measures of anxiety, depression, and general symptomatology and on secondary anxiety disorder-specific measures. Based on the intention-to-treat sample, mean between-group effect sizes were d = 0.80 for the tailored treatment and d = 0.82 for the standardized treatment, versus wait-list controls. Treatment gains were maintained at 6-month follow-up. No differences were found between the 2 active treatment conditions on any of the measures, including a telephone-administered diagnostic interview conducted at posttreatment. The findings suggest that both Internet-based tailored guided self-help treatments and Internet-based standardized treatments are promising treatment options for several anxiety disorders

Patient Expectations in Internet-Based Self-Help for Social Anxiety

A number of controlled trials have demonstrated the efficacy of Internet-based cognitive-behaviour therapy for treating social anxiety disorder (SAD). However, little is known about what makes those interventions work. The current trial focuses on patient expectations as one common mechanism of change. The study examines whether patients' expectancy predicts outcome, adherence, and dropout in an unguided Internet-based self-help programme for SAD. Data of 109 participants in a 10-week self-help programme for SAD were analysed. Social anxiety measures were administered prior to the intervention, at week 2, and after the intervention. Expectancy was assessed at week 2. Patient expectations were a significant predictor of change in social anxiety (β = - .35 to - .40, all p < .003). Patient expectations also predicted treatment adherence (β = .27, p = .02). Patients with higher expectations showed more adherence and better outcome. Dropout was not predicted by expectations. The effect of positive expectations on outcome was mediated by early symptom change (from week 0 to week 2). Results suggest that positive outcome expectations have a beneficial effect on outcome in Internet-based self-help for SAD. Furthermore, patient expectations as early process predictors could be used to inform therapeutic decisions such as stepping up patients to guided or face-to-face treatment options

Refractory chronic pelvic pain syndrome in men: can transcutaneous electrical nerve stimulation help?

Objective To evaluate the effect of transcutaneous electrical nerve stimulation (TENS) for treating men with refractory chronic pelvic pain syndrome (CPPS). Patients and Methods A consecutive series of 60 men treated with TENS for refractory CPPS was evaluated prospectively at an academic tertiary referral centre. The effects of treatment were evaluated by a pain diary and by the quality of life item of the National Institutes of Health Chronic Prostatitis Symptom Index at baseline, after 12 weeks of TENS treatment, and at last known follow-up. Adverse events related to TENS were also assessed. Results The mean (95% confidence interval, CI; range) age of the 60 men was 46.9 (43.5–50.3; 21–82) years. TENS was successful after 12 weeks of treatment in 29 (48%) patients and a positive effect was sustained during a mean (95%, CI; range) follow-up of 43.6 (33.2–56; 6–88) months in 21 patients. After 12 weeks of TENS treatment, mean (95% CI) pain visual analogue scale decreased significantly (P < 0.001) from 6.6 (6.3–6.9) to 3.9 (3.2–4.6). Patients' quality of life changed significantly after TENS treatment (P < 0.001). Before TENS, all 60 patients felt mostly dissatisfied (n = 17; 28%), unhappy (n = 28; 47%) or terrible (n = 15; 25%). After 12 weeks of TENS treatment, 29 (48%) patients felt mostly satisfied (n = 5), pleased (n = 18) or delighted (n = 6). No adverse events related to TENS were noted. Conclusion TENS may be an effective and safe treatment for refractory CPPS in men, warranting randomized, placebo-controlled trials.
