Financial and educational barriers significantly impact low socioeconomic status racial and ethnic minority groups in their pursuit of health care, though less is known about the interplay of these factors in the pursuit of surgical care. This study was designed to uncover the challenges to patient understanding and compliance with pre- and postsurgical clinical advice in low-income urban environments. The data for this study were collected in spoken survey with eighty patients in 9 surgery clinics at Temple University Hospital in Philadelphia. Survey responses were coded into various groups until categories emerged. Relationships among categories were identified to generate themes and subthemes. Key facilitators of patient understanding and compliance were physician likeability and communication. Eighty (100%) patients reported that the physician always treated them with respect, which was important in their interpretation of their experience with the physician. Eighteen (23%) patients identified a language other than English as their primary language and 57 (71%) patients completed high school or less schooling, which likely influenced their communication with the physician. Eighty (100%) patients expressed that the physician always explained things in a way they could understand, focusing on clarity and thoroughness. Challenges to patient understanding and compliance were finances and social resources. Patients noted difficulty paying for medical care and a lack of support at home. Agency could facilitate use of surgical care while a lack thereof could challenge motivation. Ultimately, these themes showed how patients in this environment interact with surgical care.
Treatment of HIV-infected patients with antiretroviral therapy (ART) has effectively suppressed viral replication; however, the central nervous system is still a major target and reservoir of the virus leading to the possible development of HIV-associated neurocognitive disorders (HAND). Furthermore, a hallmark feature of HAND is the disruption of the blood–brain barrier that leads to loss of tight junction protein (TJP) complexes. Extracellular vesicles (EVs), released by every cell type in the body, occur in greater quantities in response to cellular activation or injury. We have found that inflammatory insults activate brain endothelial cells (EC) and induce the release of EVs containing TJPs such as Occludin. We thus hypothesized that HIV infection and unresolved neuroinflammation will result in the release of brain-EC derived EVs. Herein, our results show elevated levels of brain-EC EVs in a humanized mouse model of HIV infection. Furthermore, while ART reduced brain-EC EVs, it was unable to completely resolve increased vesicles detectable in the blood. In addition to inflammatory insults, HIV-1 viral proteins (Tat and gp120) increased the release of Occludin + vesicles from human brain microvasculature ECs. This increase in vesicle release could be prevented by knock-down of the small GTPase ARF6. ARF6 has been shown to regulate EV biogenesis in other cell types, and we provide further evidence for the involvement of ARF6 in brain EC derived EVs. Overall, this study offers insight into the process of brain vascular remodeling (via EVs) in the setting of neuroinflammation and thus provides possibilities for biomarker monitoring and targeting of ARF6.
Graphical abstract
Oral surveys allow patients to elaborate on their experience in the hospital, giving context to numerical values often used to assess patient satisfaction. This allows patients to speak about factors affecting satisfaction, which is important in complex, low-income populations. Spoken surveys were administered to 80 patients in surgery clinics at Temple University Hospital. Responses were transcribed and coded to analyze patient responses. Relationships among patient responses were identified, and responses were categorized to determine the most important factors related to patient satisfaction. Numerical data were also used to assess satisfaction. Patients were satisfied with their experience with the physician and the hospital, reporting averages scores of 9.73 and 9.19, respectively. Regarding physician satisfaction, patients cited effective communication and professionalism as being most important. As long as nothing went wrong, patients scored their experience outside their interactions with the physician highly. Negative experiences were mainly related to wait times and ineffective communication with office staff and were seldom related to the physician. By using a spoken survey, patients could elaborate on their responses which provides context to the numerical data. Despite the positive feedback for physicians, patients spoke openly about communication. In low-income populations, communication failures can be exacerbated by the power differential present between the patient and physician. Our study demonstrates the utility of oral surveys in understanding complex patient populations, and the results can be used to shape surgical and nonsurgical practices in similar patient populations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
