Prevalence and profiling: hazing among college students and points of intervention

OBJECTIVE: To examine university students' attitudes, behaviors, and beliefs related to hazing. METHODS: A random and representative sample of students completed a web-based survey regarding team-building and initiation behaviors (N=736). RESULTS: Thirty-six percent of the respondents participated in hazing. Greeks, males, varsity athletes, leaders, and upperclassmen were more likely to engage in hazing. Students who engaged in hazing were more likely to engage in positive team-building activities. CONCLUSIONS: Hazing is occurring on campus, although not always recognized as such by students. Various factors that would enable someone to stop a hazing situation are addressed.     

Epilepsy care in Zambia: a study of traditional healers

PURPOSE: Most people with epilepsy (PWE) reside in developing countries with limited access to medical care. In sub-Saharan Africa (SSA), traditional healers (THs) play a prominent role in caring for PWE, yet little is known about epilepsy care by THs. We conducted a multimethod, qualitative study to better understand the epilepsy care delivered by THs in Zambia. METHODS: We conducted focus-group discussions with THs, in-depth semistructured interviews with a well-recognized TH at his place of work, and multiple informal interviews with healthcare providers in rural Zambia. RESULTS: THs recognize the same symptoms that a neurologist elicits to characterize seizure onset (e.g., olfactory hallucinations, jacksonian march, automatisms). Although THs acknowledge a familial propensity for some seizures and endorse causes of symptomatic epilepsy, they believe witchcraft plays a central, provocative role in most seizures. Treatment is initiated after the first seizure and usually incorporates certain plant and animal products. Patients who do not experience further seizures are considered cured. Those who do not respond to therapy may be referred to other healers. Signs of concomitant systemic illness are the most common reason for referral to a hospital. As a consequence of this work, our local Epilepsy Care Team has developed a more collaborative relationship with THs in the region. CONCLUSIONS: THs obtain detailed event histories, are treatment focused, and may refer patients who have refractory seizures to therapy to other healers. Under some circumstances, they recognize a role for modern health care and refer patients to the hospital. Given their predominance as care providers for PWE, further understanding of their approach to care is important. Collaborative relationships between physicians and THs are needed if we hope to bridge the treatment gap in SSA.     

TRAIL-R as a negative regulator of innate immune cell responses

TRAIL receptor (TRAIL-R) signaling has been implicated in inducing apoptosis in tumor cells, but little is understood about its physiological function. Here, we report the generation and characterization of TRAIL-R(-/-) mice, which develop normal lymphocyte populations but possess enhanced innate immune responses. TRAIL-R(-/-) mice exhibited increased clearance of murine cytomegalovirus that correlated with increased levels of IL-12, IFN-alpha, and IFN-gamma. Stimulation of macrophages with Mycobacterium and Toll-like receptor (TLR)-2, -3, and -4, but not TLR9, ligands resulted in high levels of TRAIL upregulation and enhanced cytokine production in TRAIL-R(-/-) cells. The immediate-early TLR signaling events in TRAIL-R(-/-) macrophages and dendritic cells are normal, but I kappa B-alpha homeostatic regulation and NF-kappa B activity at later time points is perturbed. These data suggest that TRAIL-R negatively regulates innate immune responses.
