One of the largest problems facing modern medicine is drug resistance. Many classes of drugs can be rendered ineffective if their target is able to acquire beneficial mutations. While this is an excellent showcase of the power of evolution, it necessitates the development of increasingly stronger drugs to combat resistant pathogens. Not only is this strategy costly and time consuming, it is also unsustainable. To contend with this problem, many multi-drug treatment strategies are being explored. Previous studies have shown that resistance to some drug combinations is not possible, for example, resistance to a common antifungal drug, fluconazole, seems impossible in the presence of radicicol. We believe that in order to understand the viability of multi-drug strategies in combating drug resistance, we must understand the full spectrum of resistance mutations that an organism can develop, not just the most common ones. It is possible that rare mutations exist that are resistant to both drugs. Knowing the frequency of such mutations is important for making predictions about how problematic they will be when multi-drug strategies are used to treat human disease. This experiment aims to expand on previous research on the evolution of drug resistance in S. cerevisiae by using molecular barcodes to track ~100,000 evolving lineages simultaneously. The barcoded cells were evolved with serial transfers for seven weeks (200 generations) in three concentrations of the antifungal Fluconazole, three concentrations of the Hsp90 inhibitor Radicicol, and in four combinations of Fluconazole and Radicicol. Sequencing data was used to track barcode frequencies over the course of the evolution, allowing us to observe resistant lineages as they rise and quantify differences in resistance evolution across the different conditions. We were able to successfully observe over 100,000 replicates simultaneously, revealing many adaptive lineages in all conditions. Our results also show clear differences across drug concentrations and combinations, with the highest drug concentrations exhibiting distinct behaviors.
This study examined the differences in mental and behavioral treatment outcomes between use of Telehealth and in-person appointments in effort to mitigate discrepancies that may lessen treatment efficacy.
Refugee women face many challenges to obtaining maternal, reproductive, and sexual health post-resettlement including the language barrier, navigating the healthcare system, finding childcare to attend appointments, and cultural mismatches between their beliefs and practices around the prenatal, childbirth, and postpartum periods and that of the healthcare system in which they resettle into. This cultural barrier poses a challenge to healthcare providers as well as it necessitates that they respect their patients’ cultural beliefs while still providing them with the highest standard of care. Cultural competency training has been used to assist providers in understanding and responding to cultural differences, but gaps still exist when it comes to navigating specific scenarios. The objective of this research was to conduct a literature review of studies pertaining to refugee maternal, reproductive, and sexual healthcare post-resettlement to investigate the following questions: how tensions between biomedically accepted best practices and cultural norms present themselves in these healthcare fields, how healthcare providers take into consideration their patients’ cultural beliefs and norms when providing maternal, reproductive, and sexual healthcare to refugee women, and what can be done to continue to improve the provision of culturally appropriate care to refugee women. Findings from twenty different studies that focused primarily on eight cultural groups identified that Cesarean sections, inductions, and certain family planning methods are significant points of contention regarding cultural norms for refugee women and that they prefer certain foods, birthing positions, and other cultural practices during the delivery. Healthcare providers consider their refugee patients’ cultural beliefs by creating relationships with them built on trust, utilizing community liaisons, and through attempts to accommodate cultural practices when possible. Some potential improvements offered to improve cultural competency were improved cultural competency training that focused on how healthcare providers ask questions and interact with their patients, increased partnership with refugee communities, and an emphasis on patient education surrounding interventions and procedures related to maternal and reproductive health that could cause hesitations. The results of this literature review accentuated the importance of relationships within the field of refugee women’s healthcare, between both refugee patients and their providers and refugee communities and the healthcare systems. Providing refugee women access to more culturally competent healthcare can increase their trust in the healthcare systems of the countries they resettle in and healthcare utilization that can contribute to improved health outcomes for refugee women and their children.
