Learning migraine self-management: the role of mothers and socioeconomic status.

One in five U.S. women have migraine. Most do not seek migraine-specific treatment, relying heavily on social networks for knowledge. Self-management is fundamental, but little is known about how women learn to self-manage during and in-between headaches. We present findings here from an exploratory qualitative study. We interviewed 6 women on how and from whom they learned to self-manage migraine. Results indicate migraine self-management strategies reflect the migraine self-management behaviors observed in trusted migraineurs - who were predominantly mothers and grandmothers. Strategies and what was learned from trusted migrainuers varied between women with higher and lower socioeconomic status. How social learning affects current self-management among women with migraine needs additional research to guide providers in understanding, and optimizing, migraine self-management counseling with their patients.

Oral Rapid HIV Testing: Implementation experiences of dental hygiene faculty and students.

Purpose: The goal of oral rapid HIV testing (ORHT) in the dental setting is to identify persons who are unaware of their positive HIV status. The purpose of this study was to describe the experiences of dental hygiene faculty and students who implemented ORHT in university-based dental hygiene clinics and to assess the facilitators and barriers to implementation of ORHT in the dental setting.Methods: Data were collected via semi-structured interviews with dental hygiene faculty and students who conducted ORHT in three dental clinics located in academic institutions. All interview sessions were audio-recorded and transcribed. An inductive approach informed by grounded theory methodology was used to code data and inform theme development. The interview sessions were completed when conceptual saturation was reached.Results: Five themes were identified by the study participants consisting of dental hygiene faculty (n= 8) and dental hygiene students (n=14). Participants felt dental hygienists are qualified to administer ORHT, which fits within their scope of practice; dental hygienists have the skills to feel comfortable offering ORHT without judgement; training is needed with ORHT administration, reading/discussing test results, and counseling for those who receive reactive results; most patients were receptive to being offered the ORHT; and patients accepted the ORHT because it was free, quick to administer and receive results, and convenient since they were already in the dental setting.Conclusion: Results from this study indicate that dental hygienists can play a key role in public health efforts to identify persons who are unaware of their HIV status.

A microbial role in the construction of Mono Lake carbonate chimneys?

Lacustrine carbonate chimneys are striking, metre-scale constructions. If these were bioinfluenced constructions, they could be priority targets in the search for early and extraterrestrial microbial life. However, there are questions over whether such chimneys are built on a geobiological framework or are solely abiotic geomorphological features produced by mixing of lake and spring waters. Here, we use correlative microscopy to show that microbes were living around Pleistocene Mono Lake carbonate chimneys during their growth. A plausible interpretation, in line with some recent works by others on other lacustrine carbonates, is that benthic cyanobacteria and their associated extracellular organic material (EOM) formed tubular biofilms around rising sublacustrine spring vent waters, binding calcium ions and trapping and binding detrital silicate sediment. Decay of these biofilms would locally have increased calcium and carbonate ion activity, inducing calcite precipitation on and around the biofilms. Early manganese carbonate mineralisation was directly associated with cell walls, potentially related to microbial activity though the precise mechanism remains to be elucidated. Much of the calcite crystal growth was likely abiotic, and no strong evidence for either authigenic silicate growth or a clay mineral precursor framework was observed. Nevertheless, it seems likely that the biofilms provided initial sites for calcite nucleation and encouraged the primary organised crystal growth. We suggest that the nano-, micro- and macroscale fabrics of these Pleistocene Mono Lake chimneys were affected by the presence of centimetre-thick tubular and vertically stacked calcifying microbial mats. Such carbonate chimneys represent a promising macroscale target in the exploration for ancient or extraterrestrial life.

Strengthening the link between policy formulation and implementation of Indigenous health policy directions.

This study aimed to understand the problems within the Indigenous health policy process in Australia and how weaknesses in the process impact on policy implementation. Using semi-structured questions, 23 key stakeholders in the policy-making process were interviewed. Three main themes dominated; a need for increased Indigenous involvement in policy formulation at the senior Australian Government level, increased participation of Indigenous community-controlled health organisations in the policy-making process and, most importantly, ensuring that policies have the necessary resources for their implementation. The emergence of these specific themes demonstrated weaknesses in policy process from the formulation stage onward. Tackling these would, according to our informants, significantly enhance the effectiveness of the policy process and contribute to further improvement of the health of Indigenous Australians.
