What do health providers and patients tweet about schizophrenia?

AIM

Twitter is the most commonly used social media forum in public health and is considered the radio of the internet. Many health providers utilize this media to disseminate health information. Patient use of social media for mental health topics encourages providers to disseminate quality information and to develop virtual collaborative learning environments. This study explored trends in health information exchanged by patients, doctors and health organizations about schizophrenia through analyses of tweets posted using the #schizophrenia.

METHODS

The likelihood that the information distributed by each user type was scholarly was assessed via qualitative and logistic regression analyses. Specifically, a sequential exploratory multimethod of data analysis guided this study with a sample of 981 tweets.

RESULTS

Most tweets focused on the improvement of schizophrenia literacy (n = 366) followed by personal experiences/motivational stories (n = 207) and biological explanations of the disorder (n = 158). Logistic regression results indicated that compared to doctors, patients were less likely to tweet with a scholarly source (OR = 0.481, CI = 0.311, .744; P < .001). All users were less likely to include a scholarly source when tweeting about schizophrenia literacy, personal/motivational experiences, campaign/organizational events or illness management in comparison to those who tweeted about biological explanations of schizophrenia.

CONCLUSION

Results suggest all users disseminated beneficial information that can increase public schizophrenia literacy and illness management, while connecting individuals to organizational events targeting this debilitating disorder. Health providers are encouraged to establish a presence on social media to share scholarly work with patients and promote prompt treatment for schizophrenia.

Family processes and duration of untreated psychosis among US Latinos

AIM

Little is known about family processes and treatment seeking among Latinos with first-episode psychosis (FEP) living in the United States. This study examined family processes prior to treatment and their relation to duration of untreated psychosis (DUP) among Latinos with FEP and their family caregivers.

METHODS

Thirty-three Latinos with FEP and their low-acculturated family caregivers (n = 33) participated in qualitative semi-structured interviews focused on treatment-seeking experience and family relationships. Transcripts were analysed using thematic analysis and themes were grouped based on short (n = 18) or long (n = 15) DUP.

RESULTS

Findings revealed differences based on DUP length. Patients with short DUP had stronger family relationships characterized by open communication and disclosure of symptoms that facilitated awareness and direct action by family caregivers. However, patients with long DUP had more troubled family relationships that often challenged early treatment seeking.

CONCLUSIONS

Findings highlight the relevance of family context in the provision of early treatment for Latinos with FEP. Family-based services are needed that increase awareness of symptoms and provide families with support that can facilitate ongoing patient treatment during this critical period.

Biomarker feedback intervention for smoking cessation among Alaska Native pregnant women: Randomized pilot study

OBJECTIVE

There is some evidence for biomarker feedback when combined with cessation counseling for reducing smoking in pregnancy. This randomized controlled pilot study evaluated feasibility and potential efficacy of a social-cognitive theory (SCT)-based biomarker feedback intervention among pregnant Alaska Native (AN) smokers.

METHODS

Participants were randomly assigned to receive three study calls (10-20 min each): (1) biomarker feedback intervention (n = 30) including personalized cotinine results and feedback on their baby's likely exposure to carcinogen metabolite NNAL, or (2) contact control usual care condition based on the 5As (n = 30). Assessments were conducted at baseline, post-treatment, and delivery.

RESULTS

High rates of treatment compliance, study retention, and treatment acceptability were observed in both groups. 7-day point prevalence smoking abstinence rates at delivery verified with urinary cotinine were the same in both study groups (20% intent-to-treat analysis, 26% per-protocol). SCT-based measures did not change differentially from baseline by study group.

CONCLUSION

This trial supports the feasibility and acceptability of providing biomarker feedback within the clinical care delivery system, but the intervention did not promote increased smoking cessation during pregnancy compared to usual care.

PRACTICE IMPLICATIONS

Efforts are needed to promote the usual care and to develop alternative biomarker feedback messaging for pregnant AN women.

Psychosis Literacy Among Latinos With First-Episode Psychosis and Their Caregivers

OBJECTIVE

The study examined psychosis literacy among Latinos with first-episode psychosis (FEP) and their caregivers. The authors tested a model that knowledge of psychosis and attribution of illness to psychosis predicted professional help seeking in a cross-sectional design.

METHODS

The sample (N=148) consisted of 79 Latino consumers who met criteria for a clinical diagnosis of a psychotic disorder and 69 family caregivers. Participants watched a four-minute narrative about a woman with psychosis and were asked to identify the symptoms of serious mental illness (knowledge of psychosis), describe the character's problem and whether she had a serious mental illness (illness attribution), and offer suggestions about what the parents should do (help seeking). Responses to the open-ended questions were reliably coded by two trained raters.

RESULTS

Consumers reported low psychosis literacy across all indices (e.g., only 8% included delusions in their knowledge of serious mental illness). Compared with consumers, caregivers reported significantly greater psychosis literacy across most indices, although relatively few reported knowledge of delusions (28%) and disorganized speech (36%). Logistic regression analyses found that caregivers were more than twice as likely as consumers to suggest that the parents seek professional help. Among both consumers and caregivers, greater knowledge of psychosis and attribution of symptoms to serious mental illness were associated with increased likelihood of recommending professional help seeking.

CONCLUSIONS

Community campaigns and psychoeducation interventions within clinical settings are needed to improve psychosis literacy among Latinos with FEP. Increasing knowledge of psychosis and facilitating attributions of psychotic symptoms to serious mental illness have the potential to promote professional help seeking.

iSpike: a spiking neural interface for the iCub robot

This paper presents iSpike: a C++ library that interfaces between spiking neural network simulators and the iCub humanoid robot. It uses a biologically inspired approach to convert the robot's sensory information into spikes that are passed to the neural network simulator, and it decodes output spikes from the network into motor signals that are sent to control the robot. Applications of iSpike range from embodied models of the brain to the development of intelligent robots using biologically inspired spiking neural networks. iSpike is an open source library that is available for free download under the terms of the GPL.
