Developing a Suicide Crisis Response Team in America: An Islamic Perspective.

Suicide is a critical public health issue in the United States, recognized as the tenth leading cause of death across all age groups (Centers for Disease Control and Prevention, 2020). Despite the Islamic prohibition on suicide, suicidal ideation and suicide mortality persist among Muslim populations. Recent data suggest that U.S. Muslim adults are particularly vulnerable, with a higher attempt history compared to respondents from other faith traditions. While the underlying reasons for this vulnerability are unclear, it is evident that culturally and religiously congruent mental health services can be utilized to steer suicide prevention, intervention, and postvention in Muslim communities across the United States. However, the development of Suicide Response toolkits specific to Muslim populations is currently limited. As a result, Muslim communities lack a detailed framework to appropriately respond in the event of a suicide tragedy. This paper aims to fill this gap in the literature by providing structured guidelines for the formation of a Crisis Response Team (CRT) through an Islamic lens. The CRT comprises of a group of individuals who are strategically positioned to respond to a suicide tragedy. Ideally, the team will include religious leaders, mental health professionals, healthcare providers, social workers, and community leaders. The proposed guidelines are designed to be culturally and religiously congruent and take into account the unique cultural and religious factors that influence Muslim communities' responses to suicide. By equipping key personnel in Muslim communities with the resources to intervene in an emergent situation, provide support to those affected, and mobilize community members to assist in prevention efforts, this model can help save lives and prevent future suicide tragedies in Muslim communities across the United States.

Clinical validation of smartphone-based activity tracking in peripheral artery disease patients.

Peripheral artery disease (PAD) is a vascular disease that leads to reduced blood flow to the limbs, often causing claudication symptoms that impair patients' ability to walk. The distance walked during a 6-min walk test (6MWT) correlates well with patient claudication symptoms, so we developed the VascTrac iPhone app as a platform for monitoring PAD using a digital 6MWT. In this study, we evaluate the accuracy of the built-in iPhone distance and step-counting algorithms during 6MWTs. One hundred and fourteen (114) participants with PAD performed a supervised 6MWT using the VascTrac app while simultaneously wearing an ActiGraph GT9X Activity Monitor. Steps and distance-walked during the 6MWT were manually measured and used to assess the bias in the iPhone CMPedometer algorithms. The iPhone CMPedometer step algorithm underestimated steps with a bias of -7.2% ± 13.8% (mean ± SD) and had a mean percent difference with the Actigraph (Actigraph-iPhone) of 5.7% ± 20.5%. The iPhone CMPedometer distance algorithm overestimated distance with a bias of 43% ± 42% due to overestimation in stride length. Our correction factor improved distance estimation to 8% ± 32%. The Ankle-Brachial Index (ABI) correlated poorly with steps (R = 0.365) and distance (R = 0.413). Thus, in PAD patients, the iPhone's built-in distance algorithm is unable to accurately measure distance, suggesting that custom algorithms are necessary for using iPhones as a platform for monitoring distance walked in PAD patients. Although the iPhone accurately measured steps, more research is necessary to establish step counting as a clinically meaningful metric for PAD.
