Tick-Borne Pathogens Associated with Medically Important Ticks in Alabama: A Four-Year Survey.

Background: Tick-borne diseases (TBDs) represent a significant threat to human health in the United States. Based on reported cases of notifiable TBDs to the Centers for Disease Control and Prevention (CDC) the state of Alabama is no exception, yet previously there has been no active surveillance program in place to comprehensively assess the presence and prevalence of tick vectors and their associated TBD pathogens in Alabama. Here we summarize initial findings from a 4-year survey to address this unmet need. Materials and Methods: Beginning in 2018 and proceeding through 2021, ticks were collected throughout the state of Alabama and pooled before being screened for a panel of TBD pathogens known to circulate in the United States. Results: Consistent with previously reported cases, TBD pathogens associated with anaplasmosis, babesiosis, ehrlichiosis, and spotted fever rickettsiosis were detected in ticks of Alabama. Causative agents for tularemia and Lyme disease were not detected despite previously reported human disease cases. There was also no evidence of Heartland virus despite recent reports of the virus being detected in ticks in Northwestern counties. Conclusions: While these results serve to provide some insights into TBD pathogens associated with ticks in Alabama, they also raise many questions that highlight the need for additional studies and continued surveillance to fully understand the TBD threat to human health in Alabama.

Evaluation of DNA-Launched Virus-Like Particle Vaccines in an Immune Competent Mouse Model of Chikungunya Virus Infection.

Chikungunya virus (CHIKV) infection can result in chronic and debilitating arthralgia affecting humans in tropical and subtropical regions around the world, yet there are no licensed vaccines to prevent infection. DNA launched virus like particle (VLP) vaccines represent a potentially safer alternative to traditional live-attenuated vaccines; however, fully characterized immunocompetent mouse models which appropriately include both male and female animals for preclinical evaluation of these, and other, vaccine platforms are lacking. Utilizing virus stocks engineered to express mutations reported to enhance CHIKV virulence in mice, infection of male and female immunocompetent mice was evaluated, and the resulting model utilized to assess the efficacy of candidate DNA launched CHIKV VLP vaccines. Results demonstrate the potential utility of DNA launched VLP vaccines in comparison to a live attenuated CHIKV vaccine and identify gender differences in viral RNA loads that impact interpretation of vaccine efficacy and may have important implications for future CHIKV vaccine development.

A Thorough Analysis of the Current State of Cancer Education in Medical Schools and Application of Experimental Teaching Techniques and Their Efficacy.

Newly diagnosed cases of cancer are expected to double by the year 2040. Although many different oncology teaching initiatives have been implemented, many students continue to report uncertainty when dealing with patients with cancer. Through this review, we aim to find the most effective teaching methods to better prepare future physicians. Papers studying different methods of teaching oncology were identified through a thorough review of specific electronic databases. Each study was analyzed and sorted into one of ten unique categories created by the authors specifically for this review. If portions of the study fit into multiple categories, relevant results would be analyzed in all applicable areas. Additionally, papers were separated and analyzed by country of origin, preclinical or clinical interventional basis, and quantitative versus qualitative form of statistical analysis. A total of 115 papers from 26 different countries and regions were included in the final analysis. 91.4% of papers analyzing Lecture and Small Group Discussions indicated a positive impact. 97.1% of papers analyzing Clinical Practice and Simulation indicated a positive impact. 100% of papers analyzing Early Experience and Mentorship, Summer Programs and Voluntary Electives, use of Multidisciplinary Teams, and Role Play stated that these methods had a positive impact. 50% of papers analyzing Computer/Web Based Programs indicated a positive impact. Clinical Practice and Simulation, Role Play, Summer/Elective Programs and interventions involving Multidisciplinary Team Work all appeared to be most effective. Intensive Block Programs, Didactic Lectures/Small Group Discussions, and Computer/Web Based Education tools as a whole were variable. General Review papers showed continued variability in domestic and international oncology curricula. Incorporation of effective teaching interventions should be highly considered in the future creation of standardized oncology curricula in order to best prepare the next generation of physicians. Future studies could explore the differing efficacies of teaching interventions in the postgraduate versus graduate realms.

Association of age, gender, obesity and hypertension with obstructive sleep apnea (OSA) among Filipino obstructive sleep apnea patients undergoing sleep study at St. Luke's Medical Center from 1998-2002

BACKGROUND: Studies have shown a high prevalence of OSA among the middle-aged group, the male gender and among the obese population. The last two years has likewise shown that OSA is a risk factor for hypertensionOBJECTIVE:To determine the association of age, gender, obesity and hypertension with OSA among Filipino OSA patientsMATERIALS AND METHODS:Cross-sectional study from previous records of polysomnography at St. Lukes Medical Center. Chi-square test of association analysis was performed with the level of significance set at 0.05.RESULTS: A significant association between age, male gender, obesity and OSA is observed (p value: 0.001). This study showed that hypertension is prevalent among OSA patients (41.3 percent) than those without OSA (33.3 percent), however no statistical significance is noted (p value: 0.132).CONCLUSION: The male gender, middle-age group and obesity are strongly associated with OSA in Filipino patients.
