Project description:ObjectivesDue to the continued impact of coronovirus 2019 (COVID-19), residency programs were advised to offer virtual interviews in place of traditional in-person interviews for the 2021 match recruitment season. As a result, many pathology residency programs offered preinterview virtual open-house events to meet prospective applicants before the interview season. This article aims to understand applicants' perspective on those events during the residency recruitment season of 2020 to 2021.MethodsWe performed a cross-sectional survey-based study involving 95 pathology residency applicants.ResultsOur results demonstrated that applicants generally have a positive perception of open house events; 91% found virtual open-house events beneficial, 63.2% attended open-house events for programs they were not considering applying to. Considering the high number of offered virtual open house events, 17% of applicants felt overwhelmed by attendance and 30% felt obligated to attend.ConclusionsThis brief report demonstrates the generally positive impact of these events.

Project description:Onboarding is a system frequently used in the corporate world as a means of orienting incoming employees to their duties and inculcating the workplace values. The program aims to facilitate transition into new work roles and improve employee retention rates. At Montefiore, we have instituted an onboarding curriculum that is given to new anatomic and clinical pathology residents about a month prior to the start of residency. The program includes an introductory video series of basic histology and a series of anatomic and clinical case studies illustrating basic laboratory principles. This didactic content is tagged to learning objectives and short self-assessment modules. In addition, content related to the work ethos at Montefiore and the role of the core competencies and milestones in residency education are included. Finally, a broader component of the onboarding gives the incoming residents a social welcome to our area, including key information about living in the area surrounding Montefiore. The program has been well received by our residents for whom the content has helped to boost confidence when starting. We feel that the program is helpful in ensuring that all incoming residents start having received the same baseline didactic content. Transmitting this didactic content via onboarding allows our residents to begin the work of learning pathology immediately, rather than spending the first weeks of residency covering remedial content such as basic histology. Such a program may be useful to other pathology residencies, most of whom have residents from a range of backgrounds and whose prior exposure to pathology may be limited.

Project description:Co-inhibitory pathways have a fundamental function in regulating T cell responses and control the balance between promoting efficient effector functions and restricting immune pathology. The TIGIT pathway has been implicated in promoting T cell dysfunction in chronic viral infection. Importantly, TIGIT signaling is functionally linked to IL-10 expression, which has an effect on both virus control and maintenance of tissue homeostasis. However, whether TIGIT has a function in viral persistence or limiting tissue pathology is unclear. Here we report that TIGIT modulation effectively alters the phenotype and cytokine profile of T cells during influenza and chronic LCMV infection, but does not affect virus control in vivo. Instead, TIGIT has an important effect in limiting immune pathology in peripheral organs by inducing IL-10. Our data therefore identify a function of TIGIT in limiting immune pathology that is independent of viral clearance.

Project description:Background Anaemia has been reported to be associated with cognitive decline and Alzheimer’s disease (AD), but the associations between anaemia and cerebrospinal fluid (CSF) AD biomarkers are still unknown. This study aimed to investigate the associations between anaemia and CSF AD biomarkers. Methods Participants were included from the Chinese Alzheimer’s Biomarker and LifestylE (CABLE) study. The associations of anaemia and its severity with CSF AD biomarkers including β-amyloid 1–42 (Aβ42), total tau (t-tau) and phosphorylated tau (p-tau) were analysed by multiple linear regression models. Adjusted for age, gender, educational levels, APOE ε4 alleles, comorbidities (history of coronary heart disease, history of stroke, hypertension, diabetes mellitus, dyslipidaemia) and glomerular filtration rate. Results A total of 646 cognitively normal older adults, consisting of 117 anaemia patients and 529 non-anaemia individuals, were included in this study. Anaemia patients had lower levels of CSF Aβ42 than individuals without anaemia (p = 0.035). Besides, participants with more severe anaemia had lower CSF Aβ42 levels (p = 0.045). No significant association of anaemia with CSF t-tau and p-tau levels was found. Conclusion Cross-sectionally, anaemia was associated with lower CSF Aβ42 levels. These findings consolidated the causal close relationship between anaemia and AD. Supplementary Information The online version contains supplementary material available at 10.1186/s12883-021-02487-z.

Project description:From 2010 to 2019, 40.5% fewer senior students from United States (US) allopathic medical schools pursued pathology in the Main Residency Match. To possibly explain this trend, we sought to identify major concerns about pathology which were made during this time. Because the Student Doctor Network (SDN) website is widely used by students at American medical schools during the residency application process, SDN has been shown to influence career decisions. So, the 50 all-time most-viewed SDN pathology threads (as of February 2018) were analyzed. The words "job" and "jobs" were used in the title of 11 of the 50 (22%) threads, which altogether received more than 400,000 views. However, the term "job(s)" was rarely used by 14 other major medical specialties. Seven of the 11 (63.6%) job-related threads were created from 2009 to 2011, corresponding with the start of the decline in medical students pursuing pathology residency. It was reasoned that job-market concerns within SDN threads may have discouraged students from pursuing pathology. To test this hypothesis, 5 pathology residents were asked to read all 11 threads and then complete a survey. Most thread reviewers agreed that commenters, which included medical students, were concerned about the pathology job-market and that medical students who viewed the threads would be less likely to pursue pathology residency. Because more than 85% of SDN users are from the US, the threads likely had a greater impact on American medical students compared to foreign students. In conclusion, job-market concerns over the past decade are so prominent in the SDN pathology forum that they likely contributed to fewer seniors from US allopathic medical schools pursuing pathology residency. As of 2019, there are 12 job-related threads among the 50 all-time most-viewed, including threads created in 2016 and 2017. To improve recruitment, the pathology community should carefully review and address concerns about employment opportunities. Due to conflicting reports, additional studies are needed to determine if a mismatch in workforce supply and demand warrants prompt and thoughtful intervention.
