Current methods for IgG antibody detection include enzyme immunoassays (EIA) such as the commercially available Diamedix Immunosimplicity® Measles IgG test kit and the Diamedix Immunosimplicity® Mumps IgG test kit. EIAs generally provide high sensitivity and strong specificity, however, there is a need for rapid screening of measles and mumps specific immunity in outbreak and resource-limited areas which could be solved by use a point-of-care (POC) platform.
This study aims to optimize a point-of-care device for the multiplexed detection of MeV, MuV, and RuV IgG antibodies in sera and to compare the sensitivity to commercial enzyme immunoassays. The IgG antibody levels to MeV and MuV were measured using EIA test kits for a total of 44 healthy serum samples. Of the samples, 6% were seronegative for MeV-specific IgG antibodies and 75% were seronegative for MuV-specific antibodies, showing low correlation of IgG antibody levels between both viruses.
To improve the sensitivity of the POC device, multiple conjugated fluorescent secondary antibodies were tested with different surface chemistries. Signal detection was measured using the pre-developed four-site slide reader. Preliminary data show that Nile Red microspheres provide robust signal detection and should be the secondary antibody of choice when sera are tested for IgG antibodies using the POC platform in future work.
DNA nanotechnology is ideally suited for numerous applications from the crystallization and solution of macromolecular structures to the targeted delivery of therapeutic molecules. The foundational goal of structural DNA nanotechnology was the development of a lattice to host proteins for crystal structure solution. To further progress towards this goal, 36 unique four-armed DNA junctions were designed and crystallized for eventual solution of their 3D structures. While most of these junctions produced macroscale crystals which diffracted successfully, several prevented crystallization. Previous results used a fixed isomer and subsequent investigations adopted an alternate isomer to investigate the impact of these small sequence changes on the stability and structural properties of these crystals. DNA nanotechnology has also shown promise for a variety biomedical applications. In particular, DNA origami has been demonstrated as a promising tool for targeted and efficient delivery of drugs and vaccines due to their programmability and addressability to suit a variety of therapeutic cargo and biological functions. To this end, a previously designed DNA barrel nanostructure with a unique multimerizable pegboard architecture has been constructed and characterized via TEM for later evaluation of its stability under biological conditions for use in the targeted delivery of cargo, including CRISPR-containing adeno-associated viruses (AAVs) and mRNA.
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.
