RESUMO

Background: The shift from in-person to virtual residency interviews may impact greenhouse gas emissions (GHGE) and costs but the direction and amount of this change is not yet clear. Objective: To estimate GHGE and financial impacts of virtual interviews among applicants and programs. Methods: In 2020-2021 we sent a postinterview survey to 1429 applicants from 7 residency programs and 1 clinical psychology program at 1 institution. The survey collected origin of travel and transit type if in-person interviews had been held and excluded responses if the applicant would not have participated in an in-person interview, or if travel type or original city was missing. We used the International Civil Aviation Organization calculator to estimate flight-related GHGE in metric tons of carbon dioxide equivalent (MTCO2e) and Google Maps to estimate ground travel, with a standard CO2e per mile. Flight, hotel, and airport taxi costs were estimated using Expedia.com, Hotels.com, Uber, and Lyft. We aggregated these data and calculated median and interquartile ranges (IQRs) for applicant GHGE and cost savings, and assumed no cost or GHGE from virtual interviews. We used Wilcoxon signed rank sum tests to compare in-person 2019-2020 and virtual 2020-2021 GME program interview budgets. Results: The survey response rate was 565, or 40% of applicants; 543 remained after the exclusion criteria were applied. Reduction in applicant travel due to virtual interviews led to median estimated GHGE savings of 0.47 (IQR 0.30-0.61) MTCO2e and $490 (IQR $392-$544) per applicant, per interview. Programs savings ranged from $7,615 to $33,670 for the interview season. Conclusions: Virtual interviews in 8 GME programs were associated with lower estimated GHGE and costs, for applicants and programs, compared with in-person interviews.

RESUMO

BACKGROUND AND OBJECTIVES: Virtual residency interviews were widely utilized during the COVID-19 pandemic. Little is known about the effectiveness, advantages, barriers, and acceptability of virtual interviews, casting uncertainty about how interviews should be conducted after the pandemic. We conducted a survey of interviewers to inform future decisions. METHODS: We developed and implemented an online postinterview survey of interviewers representing seven residency programs and two clinical psychology programs at one midsized academic medical center. We analyzed results using descriptive statistics. RESULTS: Of 312 interviewers, 136 completed the survey (44% response rate). A majority rated virtual interviews as very or extremely effective in creating a comfortable setting (79%), answering interviewee questions (86%), establishing a sense of connection (59%), evaluating interviewee strengths (64%), and communicating program culture (51%). About half felt virtual interviews were not effective at all or only slightly effective for evaluating interviewee strengths via informal interactions (51%). A similar portion agreed or strongly agreed that virtual tours (44%) and social environment (50%) information were adequate. The most frequent advantages were time efficiency (81%), reduced carbon footprint (61%) and cost savings (56%). Frequent disadvantages included technological issues (21%) and caregiving duties (18%). Most interviewers (91%) thought some form of virtual interviews should be incorporated postpandemic. CONCLUSIONS: Interviewers found virtual interviews to be effective in most aspects, and identified more advantages than barriers. The vast majority preferred incorporation of virtual interviews in the future. Virtual tours and social activities were areas for improvement.

RESUMO

Background: Studies of the virtual interview format are needed to inform medical residency program leaders as they plan for future virtual interview seasons. Objective: In the current study, completed in 2021, we sought to assess applicant perspectives of virtual interview effectiveness, advantages, and barriers, including factors that might impact equity and inclusion. Methods: Interviewees applying to 7 residency programs and 2 clinical psychology programs at an academic medical center in the Pacific Northwest completed a post-interview survey. Results: A total of 565 of 1429 interviewees (40%) completed the survey. A vast majority (83%-96%) agreed virtual interviews were effective in each measured domain, except for learning institutional culture (352 of 565, 62%). Many also found information regarding social/living environments inadequate. Participants selected advantages to virtual interviews more frequently than disadvantages. Commonly selected advantages included cost savings, time efficiency, reduced burden of travel, and reduced carbon footprint. Disadvantages included time zone differences, access to an appropriate interview setting, and reliable access to internet. The majority of interviewees (84%, 456 of 542) desired to keep a component of virtual interviews in the future. There were no significant disparities in results based on gender, rural/suburban/urban location, race, or underrepresented minority status. Conclusions: Virtual interviews were perceived as effective, more advantageous than burdensome, and widely acceptable, with no disparities in these findings by included demographic characteristics.

RESUMO

Bleeding disorders are common. In addition to thinking about disorders relating to abnormal platelets or clotting factors, clinicians should consider disorders of vascular integrity in their differential diagnosis. We present a patient with atypical, spontaneous bleeding that was due to scurvy, an often overlooked cause. Clinicians should be aware of the risk factors for the development of scurvy, such as poor dietary intake, male gender, smoking, alcohol abuse, as well as its classic manifestations, including gingival bleeding, spontaneous bruising, corkscrew hairs, and poor wound healing, A heightened awareness may lead to earlier diagnosis and treatment.

RESUMO

With the introduction of massively parallel, microminiature-based instrumentation for DNA sequencing, robust, reproducible, optimized methods are needed to prepare the target DNA for analysis using these high-throughput approaches because the cost per instrument run is orders of magnitude more than for typical Sanger dideoxynucleotide sequencing on fluorescence-based capillary systems. The methods provided by the manufacturer for genome sequencing using the 454/Roche GS-20 and GS-FLX instruments are robust. However, in an effort to streamline them for automation, we have incorporated several novel changes and deleted several extraneous steps. As a result of modifying these sample preparation protocols, the number of manual manipulations has also been minimized, and the overall yields have been improved for both shotgun and mixed shotgun/paired-end libraries.

RESUMO

The microbiota of an animal's intestinal tract plays a vital role in the animal's overall health. There is a surprising scarcity of information on the microbial diversity in the gut of livestock species such as cattle and swine. Here we describe a bacterial 16S-based tag-encoded FLX amplicon pyrosequencing (bTEFAP) method that we have developed as a high-throughput universal tool for bacterial diversity, epidemiology, and pathogen detection studies. This method will allow hundreds of samples to be run simultaneously but analyzed individually or as groups. To test this new methodology, we individually evaluated the bacterial diversity in the ileum of 21 pigs. Ubiquitous bacteria detected in the newly weaned pigs were Clostridium spp., Lactobacillus spp., and Helicobacter spp. Many of the pigs had surprisingly low concentrations of beneficial bacteria such as Bifidobacterium spp. Only four of the pigs were shown to be positive for Salmonella spp. using traditional culture methods. A total of eight pigs were bTEFAP positive for Salmonella spp., including all four of the pigs that had been culture positive. Two of the pigs sampled were also positive for Campylobacter spp. tentative identified as jejuni. Using rarefaction curves modeled with the Richards equation, we estimated the maximum number of unique species level (3% dissimilarity) operational taxonomic units in the ileum of these pigs. These predictions indicated that there may be as many as 821 different species associated with the ileum in pigs. Together these data indicate a powerful potential of this technology in food safety and epidemiological and bacterial diversity applications. Using bTEFAP, we can expect to gain a better understanding of how the microbiome of an animal contributes to its health and well-being.

RESUMO

We report the genome sequence of Theileria parva, an apicomplexan pathogen causing economic losses to smallholder farmers in Africa. The parasite chromosomes exhibit limited conservation of gene synteny with Plasmodium falciparum, and its plastid-like genome represents the first example where all apicoplast genes are encoded on one DNA strand. We tentatively identify proteins that facilitate parasite segregation during host cell cytokinesis and contribute to persistent infection of transformed host cells. Several biosynthetic pathways are incomplete or absent, suggesting substantial metabolic dependence on the host cell. One protein family that may generate parasite antigenic diversity is not telomere-associated.

RESUMO

Duffy antigen is the receptor used by Plasmodium vivax to invade erythrocytes. Consequently, individuals lacking Duffy antigen [Fy(-)] do not develop blood-stage infections. We hypothesized that naturally exposed Fy(-) humans may develop immune responses mainly to pre-erythrocytic stages and could be used to study acquired immunity to P. vivax and to identify liver-stage antigens. We report here that antibody and IFN-gamma responses to known sporozoite antigens were significantly induced by natural exposure in Fy(-) humans, whereas responses to blood-stage antigens were significantly induced in Fy(+) humans. IFN-gamma responses to sporozoite antigens were lower in Fy(+) than in Fy(-) humans, indicating that in Fy(+) humans blood-stage infections may have suppressed T cell responses to pre-erythrocytic stages. We evaluated the immune responses to 18 novel P. vivax homologs of P. falciparum sporozoite proteins identified from the P. vivax genome sequence. Eight proteins recalled IFN-gamma responses in P. vivax-exposed but not in unexposed individuals. Of these, 3 antigens elicited IFN-gamma responses in Fy(-) but not in Fy(+) individuals. These results suggest that differential immune responses observed in naturally exposed Fy(-) and Fy(+) individuals can be exploited to identify P. vivax stage-specific antigens.
