RESUMO

Background: This study focuses on the use of reflective teaching journals by fourth year US allopathic medical school students (MS4) during a longitudinal medical student-as-teacher (SaT) elective, and how MS4s self-assess their perceptions around teacher skill development and individual transitions into resident educators who teach junior learners. Method: Between September 2020 and December 2020, twelve MS4s in a longitudinal SaT elective completed 21 hours in a clinical bedside student teaching placement with embedded structured reflective teaching journals. Sixty-nine individual reflective teaching journal entries were collected in two distinct stages and analyzed using a phenomenographical lens. Conclusion: From these data, the author established three thematic categories where reflective teaching journals reveal (a) a framework for pedagogical skill building, (b) provided a sense-making tool to navigate the psychosocial environment, and (c) a framework for educator identity formation. Structured reflective teaching journals with educator feedback support self-reflection and awareness of growth through the SaT elective. Health professions educators can leverage the reflective teaching journal as a formative assessment process to help learners identify transitions and grapple with educator identity confidence and the formation of new teacher skill development to further advance the field of future health professions education.

RESUMO

A persisting need remains for developing methods for inspiring and teaching undergraduate medical students to quickly learn to identify the hundreds of human brain structures, tracts and spaces that are clinically relevant (viewed as three-dimensional volumes or two-dimensional neuroimages), and to accomplish this with the option of virtual on-line methods. This notably includes teaching the essentials of recommended diagnostic radiology to allow students to be familiar with patient neuroimages routinely acquired using magnetic resonance imaging (MRI) and computed tomography (CT). The present article includes a brief example video plus details a clinically oriented interactive neuroimaging exercise for first year medical students (MS1s) in small groups, conducted with instructors either in-person or as an entirely online virtual event. This "find-the-brain-structure" (FBS) event included teaching students to identify brain structures and other regions of interest in the central nervous system (and potentially in head and neck gross anatomy), which are traditionally taught using brain anatomy atlases and anatomical specimens. The interactive, small group exercise can be conducted in person or virtually on-line in as little as 30 min depending on the scope of objectives being covered. The learning exercise involves coordinated interaction between MS1s with one or several non-clinical faculty and may include one or several physicians (clinical faculty and/or qualified residents). It further allows for varying degrees of instructor interaction online and is easy to convey to instructors who do not have expertise in neuroimaging. Anonymous pre-event survey (n = 113, 100% response rate) versus post-event surveys (n = 92, 81% response rate) were attained from a cohort of MS1s in a neurobiology course. Results showed multiple statistically significant group-level shifts in response to several of the questions, showing an increase in MS1 confidence with reading MRI images (12% increase shift in mean, p < 0.001), confidence in their approaching physicians for medical training (9%, p < 0.01), and comfort levels in working online with virtual team-based peers and with team-based faculty (6%, p < 0.05). Qualitative student feedback revealed highly positive comments regarding the experience overall, encouraging this virtual medium as a desirable educational approach.

RESUMO

The objective of this study was to identify the endometrial gene expression profile in receptive phase, which could represent a useful prognostic tool for selecting IVF patients. Endometrial expression of 47 selected genes biopsied during the window of implantation in natural cycles was compared between patients who achieved a successful pregnancy spontaneously or after subsequent intracytoplasmic sperm injection (ICSI) cycles and patients who did not achieve a pregnancy after at least two failed ICSI cycles. The comparative analysis showed significantly different levels of expression in 19 genes, five implicated in apoptosis (CASP8, FADD, CASP10, APAF1, ANXA4), three in immunity (LIF, SPP1, C4BPA), five in transcriptional activity (MSX1, HOXA10, MSX2, HOXA11, GATA2), two in lipid metabolism (LEPR, APOD) and four in oxidative metabolism (AOX1, ALDH1A3, GPX3, NNMT). The evidence for these genes being differently expressed could represent the starting point of identifying the ideal receptive endometrial gene expression profile, which could be used in the future as a prognostic tool for IVF patients. Gene expression analysis technology has opened new important perspectives on the study of the physiological processes of different tissues and organs. Specifically for the endometrium, it would be really interesting to find out an endometrial gene expression profile of receptive phase, which could be used in future as a useful prognostic tool for selecting IVF patients. To achieve this aim, the objective of the present paper was the comparison of endometrial expression in natural cycles of 47 selected genes between the biopsies of patients who achieved a successful pregnancy, either spontaneously or after subsequent ICSI cycles, and those of patients who did not achieve a pregnancy after at least two failed ICSI cycles. The comparative analysis showed a significant different expression in 19 genes: five implicated in programmed cell death, known as apoptosis (CASP8, FADD, CASP10, APAF1, ANXA4), three in immunity (LIF, SPP1, C4BPA), five in transcriptional activity (MSX1, HOXA10, MSX2, HOXA11, GATA2), two in lipid metabolism (LEPR, APOD) and four in oxidative metabolism (AOX1, ALDH1A3, GPX3, NNMT). The evidence of these genes being differently expressed could represent the starting point of identifying the ideal receptive endometrial gene expression profile which could be used in the future as a prognostic tool for IVF patients.

RESUMO

OBJECTIVE: To determine whether increased patient interaction, exposure to the neurologic examination, and access to positive neurology mentors increase interest in neurology for first-year medical students. METHODS: Neuro Day was a 2-part experience for first-year medical students. The first part consisted of a flipped classroom to teach the standard neurologic examination. The second part involved patient encounters modeled off of the traditional patient rounds. Students rotated from room to room, listening to patients' experiences with different neurologic diseases and eliciting pathologic neurologic examinations. Students were surveyed before and after Neuro Day. RESULTS: The result of the binomial test indicated that the proportion of medical students interested in neurology significantly increased from 78% to 85% (95% confidence interval [CI] 0.79-0.92; p = 0.034) after participating in Neuro Day. The proportion of students' knowledge of clinical neurology increased from 45% to 63.1% (95% CI 0.54-0.72; p < 0.0001), comfort with performing a neurologic examination increased from 30% to 78.4% (95% CI 0.70-0.86; p < 0.0001), and fear of studying neurology decreased from 46% to 26% (95% CI 0.17-0.34; p < 0.0001) following Neuro Day. One hundred percent of students indicated that they would recommend Neuro Day to their peers. CONCLUSION: Neuro Day is a feasible and effective model to incorporate into medical education. There was increased interest in and decreased fear of neurology. We anticipate that this paradigm can be used in the future to encourage students to consider a career in neurology.

RESUMO

First-year medical student groups rotated through classrooms, each containing a Neurology patient and physician, as a "Neuro Day" event to make direct clinical connections with the basic sciences. Inspired by post-graduate Clerkships, this event provided timely first-hand experiences focusing on pathological neurologic exam findings. Qualitative and quantitative data were collected from end-of-course surveys. The results show how the event served to reinvigorate enthusiasm for learning Clinical Neurobiology outside the traditional lecture environment and could empower patients as educators within a teaching community.

RESUMO

Background Miscommunication amongst providers is a major factor contributing to diagnostic errors. There is a need to explore the current state of communications between clinicians and diagnostic radiologists. We compare and contrast the perceptions, experiences, and other factors that influence communication behaviors about diagnostic errors between clinicians and radiologists. Methods A survey with questions addressing (1) communication around diagnostic error, (2) types of feedback observed, (3) the manner by which the feedback is reported, and (4) length of time between the discovery of the diagnostic error and disclosing it was created and distributed through two large academic health centers and through listservs of professional societies of radiologists and clinicians. Results A total of 240 individuals responded, of whom 58% were clinicians and 42% diagnostic radiologists. Both groups of providers frequently discover diagnostic errors, although radiologists encounter them more frequently. From the qualitative analysis, feedback around diagnostic error included (1) timeliness of error, (2) specificity in description or terminology, (3) collegial in delivery, and (4) of educational value through means such as quality improvement. Conclusions Clinicians and radiologists discover diagnostic errors surrounding the interpretation of radiology images, although radiologists discover them more frequently. There is significant opportunity for improvement in education and practice regarding how radiologists and clinicians communicate as a team and, importantly, how feedback is given when an error is discovered. Educators and clinical leaders should consider designing, implementing, and evaluating strategies for improvement.

RESUMO

With the advent of recorded lectures, face-to-face teaching in medical school large classroom settings is increasingly under pressure to incorporate engaging activities that encourage attendance and can translate to greater attainment and long-term retention for learners, especially of "Generation Z" learning styles. This places a greater onus on lecturers to convey key concepts in a manner that holds value beyond their recorded substitute. The present article details several on-stage Medical Gross Anatomy and Neurobiology demonstrations that involve the teaching of an intuitive understanding of brain fluidic mechanics, such as hematoma formation and the protective functions of an intact cerebral spinal fluid system (addressing concussion and lumbar punctures). These demonstrations can be presented relatively quickly on stage and are suitable for engaging large classroom sizes (n > 100), which can be used in conjunction with traditional lecture formats. Ideally, these in-class demonstrations, together with the continued contributions of other quantitatively assessed demonstrations from other institutions, will help to maintain a growing body of large class face-to-face teaching approaches and strategies to help influence decisions regarding what basic medical knowledge may best be taught in class live versus by recorded substitute or other non-traditional lecture methods.

RESUMO

BACKGROUND AND OBJECTIVES: The current study compared the cervical cytological sub-category "atypical squamous cells of undetermined significance-favour reactive (AFR)", recently recommended to be eliminated by the Bethesda system, to the sub-category "atypical squamous cells of undetermined significance-favour dysplasia (ASC-US)", in terms of prevalence of coexistent squamous intraepithelial lesions of either low-grade (LSIL) or high-grade (HSIL) and rate of human papillomavirus (HPV) infection. STUDY DESIGN: One hundred women with AFR and 100 with ASC-US were consecutively included in the study. All patients underwent colposcopy, followed by biopsy when necessary, and were screened for HPV infection by the combined use of Hybrid Capture II (DIGENE) and PCR with MY09/11 primers, the latter followed by direct sequencing of the amplifications products for HPV genotyping. RESULTS: LSIL were detected in 5.6% of AFR and 18.5% of ASC-US (p=0.00812), HSIL only in 4.3% of ASC-US. HPV infection was diagnosed in 11.2% of AFR and 38.0% of ASC-US (p=0.00003); high-risk HPV types (namely, HPV-16, -18, -31, -66, -67 and -70) were found in 6.7% of AFR and 22.8% of ASC-US (p=0.00239). Evidence of HPV infection in absence of SIL was proven in 7.1% of AFR and in 22.5% of ASC-US (p=0.00622). CONCLUSION: The association of AFR with SIL and high-risk HPV infection is low but not inexistent. Thus, to avoid the risk of leaving some high-risk AFR patients untreated or without follow-up, it could be proposed to keep AFR as a cytological category and to triage it by HPV testing, similarly to what has been already recommended for ASC-US.

RESUMO

OBJECTIVES: Our objectives were to determine the prevalence of human papillomavirus (HPV) infection in oral leukoplakia (OL) and oral lichen planus (OLP) in comparison with that in healthy oral mucosa, also conditionally to age, gender, smoking, and drinking habits of patients, so as to investigate any possible association of HPV infection with a specific clinical variant of OL or OLP. STUDY DESIGN: We did research on HPV DNA in 68 cases of OL (homogeneous form [H] in 45 cases and nonhomogeneous form [non-H] in 23 cases), and in 71 cases of OLP (nonatrophic/erosive form [non-AE] in 27 cases, atrophic/erosive form [AE] in 44 cases). HPV DNA was investigated in exfoliated oral mucosa cells by nested PCR (nPCR: MY09-MY11/GP5-GP6) and the HPV genotype determined by direct DNA sequencing. RESULTS: HPV DNA was found in 17.6% of OL, in 19.7% of OLP, and in 5.6% of controls, with a statistically significant higher risk of HPV infection in both lesion groups (for OL: P=.01; Odds Ratio [OR]=3.64; 95% CI: 1.21-10.80; for OLP: P=.005; OR=4.17; 95% CI: 1.41-12.18). Demographic variables analysis showed that the only significant association was between HPV status and current smoking in OL patients (OR'=3.40; 95% CI: 1.0-11.59). HPV DNA was found in 20% of H OL and 13% of non-H OL, without any association with the clinical variant (P=.73; OR=0.60; 95% CI: 0.14-2.48). HPV DNA was found in 18.5% of non-AE OLP and 20.4% of AE OLP, without any significant association with the clinical variant (P=.84; OR=1.13; 95% CI: 0.335-3.816). HPV-18 was the most frequently detected genotype (9/12 and 10/14 of HPV-positive OL and OLP, respectively), followed by HPV-16 (2/12 OL and 2/14 OLP), HPV-33 (1/12 OL), HPV-31 (1/14 OLP), and HPV-6 (1/14 OLP). CONCLUSIONS: An increased risk of HPV infection was found in OL and OLP; however, no specific clinical variant of OL or OLP was noted to be associated with HPV infection. It is not possible to predict the likelihood of HPV infection from the clinical features of OL and OLP.

RESUMO

This study determined the presence of human papillomavirus (HPV) DNA in oral mucosa cells from 121 patients with different types of oral mucosal lesions (13 squamous cell carcinomas, 59 potentially malignant lesions, 49 benign erosive ulcerative lesions) and from 90 control subjects. HPV DNA was detected by nested polymerase chain reaction, and genotype was determined by DNA sequencing. HPV prevalence was 61.5% in carcinomas, 27.1% in potentially malignant lesions, 26.5% in erosive ulcerative lesions, and 5.5% in control subjects. The risk of malignant or potentially malignant lesions was associated with HPV and was statistically significant. HPV-18 was found in 86.5% of HPV-positive lesions but was not associated with a particular type of lesion and was found in 80% of the HPV-positive control subjects. HPV infection was related to older age but not to sex, smoking, or alcohol use; the presence of lesions in the oral cavity increased the risk of HPV infection.
