RESUMO

BACKGROUND: The clinical demands for hospitalist groups have grown at academic medical centers, without similar growth of teaching opportunities for faculty. Traditional resident teaching teams are often crowded with learners which can limit acting intern (or subintern) patient encounters. Medical students are often placed on nonresident teaching teams, although there are few studies on learner experience on a nonresident teaching team model. METHODS: To address these concerns, we created two nonresident teaching teams composed of one attending and two acting interns. We compared acting intern experience on the nonresident teaching teams to the traditional resident teams to determine if there were significant differences in student experience by reviewing course evaluation data on the two team models. RESULTS: Of the 276 students who completed the Internal Medicine Acting Internship from 2019 to 2023, 224 students (81%) completed the course evaluation. The course was highly rated, and the ratings were similar in both models demonstrating that the nonresident teaching team model is an effective option for acting interns. CONCLUSION: The nonresident teaching team model can offload crowded teaching teams, add additional acting intern experiences, and add teaching opportunities for hospital medicine attendings.

RESUMO

BACKGROUND: Narrative written feedback given to students by faculty often fails to identify areas for improvement and recommended actions to lead to this improvement. When these elements are missing, it is challenging for students to improve and for medical schools to use narrative feedback in promotion decisions, to guide coaching plans and to pass on meaningful information to residency programs. Large-group faculty development has improved narrative written feedback, but less is known about individualised faculty development to supplement large-group sessions. To fill this gap, we built a curriculum with general and individualised faculty development to improve narrative written feedback from Internal Medicine faculty to clerkship students. APPROACH: We used Kern's steps to build a curriculum with general and individualised one-on-one faculty development to improve the problem of inadequate narrative written feedback. We used a novel narrative feedback rubric for pre and post-intervention faculty scores. RESULTS/FINDINGS/EVALUATION: Through general and individualised one-on-one faculty development with peer comparison scores, we were able to improve narrative written feedback from 3.7/6 to 4.6/6, for an increase of 23%. IMPLICATIONS: We found our faculty development program effective in improving feedback and was easy to implement. Our rubric was easy to use, and faculty were receptive to feedback in one-on-one meetings. We plan to extend this work locally to other divisions/departments and into graduate medical education; it should also be easily extended to other medical disciplines or health professions.

RESUMO

OBJECTIVES: Acknowledging that a successful career in hospital medicine (HM) requires specialized skills, residency programs have developed hospital medicine-focused education (HMFE) programs. Surveys of Internal Medicine residency leaders have described HMFE curricula but are limited to that specialty and lack perspectives from early career hospitalists (ECHs) who recently completed this training. As such, we surveyed multispecialty ECHs to evaluate their preferences for HMFE and to identify gaps in standard residency training and career development that HMFE can bridge. The objectives of our study were to describe multispecialty ECH needs and preferences for HMFE and to identify gaps in standard residency training and career development that HMFE can bridge. METHODS: From February to March 2021, ECHs (defined as hospitalists within 0-5 years from residency) were surveyed using the Society of Hospital Medicine's listserv. Respondents identified as having participated in HMFE or not during residency (defining them as HMFE participants or non-HMFE participants). RESULTS: From 257 respondents, 84 (33%) ECHs met inclusion criteria. Half (n = 42) were HMFE participants. ECHs ranked clinical hospitalist career preparation (86%) and mentorship from HM faculty (85%) as the most important gaps in standard residency training and career development that HMFE can bridge. Other key components of HMFE included exposure to quality improvement, patient safety, and high-value care (67%); provision of autonomy through independent rounding (54%); and preparation for the job application process (70%). CONCLUSIONS: Multispecialty ECHs describe HMFE as positively influencing their decision to pursue a hospitalist career and increasing their preparedness for practice. HMFE may be particularly well suited to foster advanced clinical skills such as independent rounding, critical thinking, and self-reflection. We propose an organizing framework for HMFE in residency that may assist in the implementation and innovation of HMFE programs nationwide and in the development of standardized HMFE competencies.

RESUMO

OBJECTIVE: There is limited data available about factors which promote competence with procedures in medical students. Specifically, the relationship between procedural clinical experience and performance on an assessment is unclear. We sought to determine whether a correlation exists between the amount and type of clinical experience with a procedure and student performance on a standardized assessment of that procedure. DESIGN: Faculty performed standardized assessments of third-year medical students on ten procedures using simulation. We prospectively surveyed students about 3 types of experience (performed, observed, and simulated) with these procedures during their clerkships. We then analyzed whether a correlation exists between student experience and their competency assessment scores using Pearson's correlation. SETTING/PARTICIPANTS: Third-year medical students at the University of Kentucky College of Medicine. RESULTS: In 2018 to 2019, 131 students were assessed on procedural competency with 10 failures. One hundred and twenty students (91.6%) completed the clinical experience survey. Correlations between types of experience and competency scores were small to moderate, with only 5 of 40 being significant. We found no correlation between experience having performed a procedure and competency score. CONCLUSIONS: Overall, we did not find convincing evidence of a correlation between experience with procedures during clerkships and performance on a competency assessment. This suggests other factors may be contributing to procedural competence, which has implications for how educators should develop procedural competence in students.

RESUMO

OBJECTIVE: To examine associations between bedside rounding (BSR) and other rounding strategies (ORS) with resident evaluations of teaching attendings and self-reported attending characteristics. METHODS: Faculty from three academic medical centers who attended resident teaching services for ≥4 weeks during the 2018-2019 academic year were invited to complete a survey about personal and rounding characteristics. The survey instrument was iteratively developed to assess rounding strategy as well as factors that could affect choosing one rounding strategy over another. Survey results and teaching evaluation scores were linked, then deidentified and analyzed in aggregate. Included evaluation items assessed resident perceptions of autonomy, time management, professionalism, and teaching effectiveness, as well as a composite score (the numeric average of each attending's scores for all of the items at his or her institution). BSR was defined as spending >50% of rounding time in patients' rooms with the team. Hallway rounding and conference room rounding were combined into the ORS category and defined as >50% of rounding time in these settings. All of the scores were normalized to a 10-point scale to allow aggregation across sites. RESULTS: A total of 105 attendings were invited to participate, and 65 (62%) completed the survey. None of the resident evaluation scores significantly differed based on rounding strategy. Composite scores were similar for BSR and ORS (difference of <0.1 on a 10-point scale). Spearman correlation coefficients identified no statistically significant correlation between rounding strategy and evaluation scores. An exploratory analysis of variance model identified no single factor that was significantly associated with composite teaching scores (P > 0.45 for all) or the domains of teaching efficacy, professionalism, or autonomy (P > 0.13 for all). Having a formal educational role was significantly associated with better evaluation scores for time management, and the number of lectures delivered per year approached statistical significance for the same domain. CONCLUSIONS: Conducting BSR did not significantly affect resident evaluations of teaching attendings. Resident perception of teaching effectiveness based on rounding strategy should be neither a motivator nor a barrier to widespread institution of BSR.

RESUMO

OBJECTIVE: Septic arthritis results from joint infection by Staphylococcus aureus, which produces potent α-toxin causing cell death, potentially leading to permanent cartilage damage. Treatment is by joint irrigation and antibiotics, although it is unclear if, following treatment with antibiotics which cause bacterial lysis, there is release of additional stored α-toxin. DESIGN: A rabbit erythrocyte hemolysis assay was optimised to assess biologically-active α-toxin from cultured S. aureus α-toxin strain DU5946. Hemoglobin release was measured spectrophotometrically following addition of a bacteriostatic antibiotic (linezolid) or a bacteriolytic antibiotic (penicillin). A bovine cartilage model of septic arthritis was used to test the protective effects of antibiotics against S. aureus infection. RESULTS: During S. aureus culture, α-toxin levels increased rapidly but the rate of rise was quickly (within 20 minutes) suppressed by linezolid (25 µg/mL). Penicillin also reduced the increase in α-toxin levels; however, the time course was relatively slow compared to linezolid even at high concentrations (50,000 U/mL). The efficacy of penicillin (250,000 U/mL) at reducing the rise in α-toxin was approximately 8% less than that of linezolid (P < 0.05) suggesting the presence of additional toxin. This could be due to a delayed action of penicillin, and/or release of a small pool of stored α-toxin from dying bacteria. In a bovine cartilage model, however, there was no difference between the protection of in situ chondrocytes against S. aureus by penicillin or linezolid (P > 0.05). CONCLUSION: The results suggested that equally effective protection of chondrocytes against S. aureus septic arthritis may be obtained by the bacteriostatic or bacteriolytic antibiotics tested.

RESUMO

BACKGROUND: Tetramethylammonium hydroxide (TMAH) is a quaternary ammonium compound that is both a base corrosive and a cholinergic agonist, and it is widely used in the photoelectric and semiconductor industries. It causes corrosive skin injuries and systemic cholinergic toxicity with death primarily resulting from respiratory failure without efficacious early decontamination. METHODS: A retrospective observational study was performed of all cases of TMAH exposure reported to the Taiwan Poison Control Center between July 2010 and October 2017. Retrieved medical records were independently reviewed by two trained clinical toxicologists. RESULTS: Despite immediate (< 5 min) skin decontamination with copious amounts of tap water, one patient exposed to 25% TMAH involving ≥5% of total body surface area (TBSA) developed significant systemic toxicity. Patients exposed to 25% TMAH involving ≤1% TBSA developed first-degree chemical skin injuries but no systemic toxicity. Among patients exposed to lower concentrations (≤2.38%) of TMAH, the majority only experienced first-degree chemical skin injuries without systemic signs. Patients exposed to 0.5% TMAH involving nearly their entire TBSA developed no chemical skin injuries or systemic toxicity. All patients who had only first-degree chemical skin injuries did not develop systemic toxicity after exposure to either 2.38% or 25% TMAH. CONCLUSIONS: TMAH acts as an alkaline corrosive and cholinergic agonist. Systemic signs attributable to TMA+ can rapidly lead to respiratory failure and death after dermal exposure. We have demonstrated that an amphoteric solution may be efficacious for skin decontamination on-site immediately to prevent or ameliorate such toxicity. This practice especially carries a valuable potential in managing victims (patients) who have been exposed to those chemicals with immediate life-threatening toxicity (e.g. TMAH), suggesting that its early utilization deserves further study.

RESUMO

Coordinated directional migration of cells in the mesoderm layer of the early embryo is essential for organization of the body plan. Here we show that mesoderm organization in mouse embryos depends on ß-Pix (Arhgef7), a guanine nucleotide exchange factor for Rac1 and Cdc42. As early as E7.5, ß-Pix mutants have an abnormally thick mesoderm layer; later, paraxial mesoderm fails to organize into somites. To define the mechanism of action of ß-Pix in vivo, we optimize single-cell live-embryo imaging, cell tracking, and volumetric analysis of individual and groups of mesoderm cells. Use of these methods shows that wild-type cells move in the same direction as their neighbors, whereas adjacent ß-Pix mutant cells move in random directions. Wild-type mesoderm cells have long polarized filopodia-like protrusions, which are absent in ß-Pix mutants. The data indicate that ß-Pix-dependent cellular protrusions drive and coordinate collective migration of the mesoderm in vivo.

RESUMO

Perineural invasion (PNI) is an ominous form of cancer progression along nerves associated with poor clinical outcome. Glial derived neurotrophic factor (GDNF) interacts with cancer cell RET receptors to enable PNI, but downstream events remain undefined. We demonstrate that GDNF leads to early activation of the GTPase Cdc42 in pancreatic cancer cells, but only delayed activation of RhoA and does not affect Rac1. Depletion of Cdc42 impairs pancreatic cancer cell chemotaxis toward GDNF and nerves. An siRNA library of guanine nucleotide exchange factors was screened to identify activators of Cdc42. ARHGEF7 (ß-Pix) was required for Cdc42 activation and chemotaxis toward nerves, and also colocalizes with RET under GDNF stimulation. Cdc42 enables PNI in an in vitro dorsal root ganglia coculture model, and controls the directionality of migration but does not affect cell speed or cell viability. In contrast, Rac1 was necessary for cell speed but not directionality, while the RhoA was not necessary for either cell speed or directionality. Cdc42 was required for PNI in an in vivo murine sciatic nerve model. Depletion of Cdc42 significantly diminished the length of PNI, volume of PNI, and motor nerve paralysis resulting from PNI. Activated Cdc42 is expressed in human salivary ductal cancer cells invading nerves. These findings establish the GDNF-RET-ß-Pix-Cdc42 pathway as a directional regulator of pancreatic cancer cell migration toward nerves, highlight the importance of directional migration in PNI, and offer novel targets for therapy. IMPLICATIONS: Cdc42 regulates cancer cell directional migration toward and along nerves in PNI.

RESUMO

OBJECTIVE: To evaluate current practices in naloxone prescribing upon hospital discharge. DESIGN: Electronic cross-sectional survey. SETTING: Academic medical center. PARTICIPANTS: Inpatient physicians and advanced practice providers. MAIN OUTCOME MEASURES: Respondents completed survey items including current naloxone prescribing practices, barriers to naloxone prescribing, and methods to improve naloxone prescribing. RESULTS: The survey response rate was 51.6 percent. Greater than 90 percent of respondents agreed that naloxone should be prescribed for patients with an active opioid use disorder, history of overdose, and use of greater than 50 morphine milligram equivalents per day. Lack of patient education on proper use of naloxone was the most identified barrier to prescribing. CONCLUSIONS: Providers agree with the Centers for Disease Control and Prevention recommendations to prescribe naloxone to high-risk patients. Certain barriers affect the rate of naloxone prescribing at discharge, including lack of time, patient education, provider training, and concern for increasing riskier behaviors.

RESUMO

The metastatic progression of cancer is a multi-step process initiated by the local invasion of the peritumoral stroma. To identify the mechanisms underlying colorectal carcinoma (CRC) invasion, we collected live human primary cancer specimens at the time of surgery and monitored them ex vivo. This revealed that conventional adenocarcinomas undergo collective invasion while retaining their epithelial glandular architecture with an inward apical pole delineating a luminal cavity. To identify the underlying mechanisms, we used microscopy-based assays on 3D organotypic cultures of Caco-2 cysts as a model system. We performed two siRNA screens targeting Rho-GTPases effectors and guanine nucleotide exchange factors. These screens revealed that ROCK2 inhibition triggers the initial leader/follower polarization of the CRC cell cohorts and induces collective invasion. We further identified FARP2 as the Rac1 GEF necessary for CRC collective invasion. However, FARP2 activation is not sufficient to trigger leader cell formation and the concomitant inhibition of Myosin-II is required to induce invasion downstream of ROCK2 inhibition. Our results contrast with ROCK pro-invasive function in other cancers, stressing that the molecular mechanism of metastatic spread likely depends on tumour types and invasion mode.

RESUMO

Despite rapidly growing interest in Hospital Medicine (HM), no prior research has examined the factors that may be most beneficial or detrimental to candidates during the HM hiring process. We developed a survey instrument to assess how those involved in the HM hiring process assess HM candidate attributes, skills and behaviors. The survey was distributed electronically to nontrainee physician Society of Hospital Medicine members. Respondents ranked the top five qualifications of HM candidates and the top five qualities an HM candidate should demonstrate on interview day to be considered for hiring. In thematic analysis of free-response questions, several themes emerged relating to interview techniques and recruitment strategies, including heterogeneous approaches to long-term versus short-term applicants. These findings represent the first published assessment in the area of HM hiring and should inform HM candidates and their mentors.

RESUMO

Corrosive chemical substance ingestions are a major problem, especially in developing countries, but also in developed countries such as the United States, France, and Belgium. Ingestions may be deliberate as suicide attempts (mostly in adolescents and adults) or accidental (mostly in children). The results can be devastating in terms of individual suffering and disability, but also in terms of resource utilization and costs. In developing countries, outcomes may be worse because of limited medical/surgical resources. Common sequelae include gastrointestinal (GI) tract (esophagus, stomach, pylorus, and duodenum) stricture formation, GI tract perforation, and hemorrhage. Systemic effects may also occur, such as disseminated intravascular coagulation (DIC), multi-organ system failure, and sepsis. Various interventions in the acute phase to reduce the severity of injury have been attempted, but there are no large controlled clinical trials to demonstrate efficacy. Dilation therapy in various forms is commonly used for the treatment of strictures and a variety of surgical procedures including esophagectomy and delayed replacement may be required in severe corrosive injury cases.

RESUMO

Objective: The primary goal of this study was to assess current maintenance intravenous fluid (mIVF) prescribing practices of pediatric hospitalists after the release of the American Academy of Pediatrics Clinical Practice Guideline (AAP CPG), specifically assessing the rates of various isotonic vs. hypotonic solutions used in discrete age groups and in common clinical scenarios associated with anti-diuretic hormone (ADH) excess and hyponatremia. We hypothesized that isotonic fluids would be selected in most cases outside of the neonatal period. Methods: A voluntary and anonymous survey was distributed to the LISTSERV® for the AAP Section on Hospital Medicine. Results: There were 402 total responses (10.1% response rate) with the majority of respondents being pediatric hospitalists. Isotonic solutions were preferred by respondents in older children compared to younger age groups, at 87.8% for the 1-18 years age group compared to 66.3% for the 28 days to 1 year age group and 10.6% for the younger than 28 days age group (all p values <0.0001). When presented with disease states associated with ADH excess, isotonic fluids were preferred in higher percentages in all age groups except in children younger than 28 days when 0.45% sodium chloride was preferred; 0.2% sodium chloride was rarely chosen. Conclusions: Overall, based on survey responses, pediatric hospitalists are following the 2018 AAP CPG on mIVF and are more likely to choose isotonic fluids as their primary mIVF in pediatric patients outside of the neonatal period, including in scenarios of excess ADH. Isotonic fluids use seems to be higher with increasing age and hypotonic fluids are more commonly chosen in the neonatal period.

RESUMO

The objective was to perform a thorough review of published and other available data to elucidate the extent of chemical skin injuries in the US. Chemical skin injuries differ significantly from skin lesions produced by other injury mechanisms, so this review was restricted to the former. Retrieval of relevant published data was performed in PubMed and Google. Other data were retrieved from the American College of Surgeons National Trauma Databank, American Burn Association National Burn Repository, US Department of Labor Bureau of Labor Statistics, websites of all 50 US States Departments of Health, and the National Poison Data System of the American Association of Poison Control Centers. Two areas of significance in disfiguring skin burn injuries and particularly of chemical skin injuries, psychosocial issues and the associated financial burden, have been briefly reviewed. Because of the paucity of published data, international as well as US data have been included. A brief description of an active flushing fluid as an alternative to potable water, Diphoterine® solution, has also been included. Chemical skin injuries generally comprise approximately 2-5% of all skin burns, but sometimes higher percentages have been reported. Data analysis shows that while there are various sources regarding the epidemiology of chemical skin injuries, the total annual number cannot be determined because there is no centralized US national reporting mechanism. Literature and clinical experience demonstrate the importance of chemical skin injuries in USA. Dermal exposures to chemicals can result in mortality and morbidity. Chemical skin injuries can be avoided or ameliorated and preventive advanced measures should be taken to reduce or ameliorate them.
