RESUMO

INTRODUCTION: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are a class of medications for management of diabetes and obesity. The objective of this study is to characterize the epidemiology of GLP-1RA cases reported to US poison centers. METHODS: We analyzed cases involving a GLP-1RA reported to the National Poison Data System during 2017-2022. RESULTS: There were 5,713 single-substance exposure cases reported to US poison centers involving a GLP-1RA. Most cases were among females (71.3%) and attributable to therapeutic errors (79.9%). More than one-fifth (22.4%) of cases were evaluated in a healthcare facility, including 0.9% admitted to a critical care unit and 4.1% admitted to a non-critical care unit. Serious medical outcomes were described in 6.2% of cases, including one fatality. The rate of cases per one million US population increased from 1.16 in 2017 to 3.49 in 2021, followed by a rapid increase of 80.9% to 6.32 in 2022. Trends for rates of serious medical outcomes and admissions to a healthcare facility showed similar patterns with 129.9% and 95.8% increases, respectively, from 2021 to 2022. CONCLUSIONS: Most GLP-1RA cases reported to US poison centers were associated with no or minimal effects and did not require referral for medical treatment; however, a notable minority of individuals experienced a serious medical outcome or healthcare facility admission. The rate of reported cases increased during the study period, including an 80.9% increase from 2021 to 2022. Opportunities exist to improve provider and patient awareness of the adverse effects of these medications.

RESUMO

BACKGROUND: Despite changes in social attitudes in the United States over the last decade, sexual and gender minority (SGM) individuals continue to face significant health disparities, driven partly by disproportionately higher rates of self-reported discrimination and harassment when seeking healthcare. Historically, physicians have received little to no required training on how to provide sensitive, competent care to SGM patients, and continue to demonstrate poor competency with SGM topics despite calls for increased education and published guidelines to promote competency. The present study aimed to investigate competency with SGM topics among both faculty and medical students at one institution. METHODS: The authors distributed an anonymous online survey (2020-2021) to medical students and student-facing faculty at one allopathic medical school in the United States. The objective of the study was to evaluate knowledge, clinical skills, and self-reported competence with SGM topics. RESULTS: Of survey respondents, 223 medical students and 111 faculty were included in final analysis. On average, medical students were significantly more likely to answer General Knowledge questions correctly (97.2%) compared to faculty (89.9%). There were no significant differences in responses to Clinical Knowledge questions between medical students and faculty. however medical students were significantly more likely to report competence with eliciting a thorough sexual history, and faculty were significantly more likely to report receiving adequate clinical training and supervision to work with lesbian, gay, and bisexual patients. CONCLUSIONS: Medical students demonstrated significantly higher general knowledge about SGM topics compared to faculty. Medical students and faculty demonstrated similarly low average clinical knowledge, with percent correct 65.6% for students and 62.7% for faculty. Despite significant differences in general knowledge and low clinical knowledge, medical students and faculty self-reported similar levels of competence with these topics. This indicates insufficient curricular preparation to achieve the AAMC competencies necessary to care for SGM patients.

RESUMO

BACKGROUND: The traditional model of promotion and tenure in the health professions relies heavily on formal scholarship through teaching, research, and service. Institutions consider how much weight to give activities in each of these areas and determine a threshold for advancement. With the emergence of social media, scholars can engage wider audiences in creative ways and have a broader impact. Conventional metrics like the h-index do not account for social media impact. Social media engagement is poorly represented in most curricula vitae (CV) and therefore is undervalued in promotion and tenure reviews. OBJECTIVE: The objective was to develop crowdsourced guidelines for documenting social media scholarship. These guidelines aimed to provide a structure for documenting a scholar's general impact on social media, as well as methods of documenting individual social media contributions exemplifying innovation, education, mentorship, advocacy, and dissemination. METHODS: To create unifying guidelines, we created a crowdsourced process that capitalized on the strengths of social media and generated a case example of successful use of the medium for academic collaboration. The primary author created a draft of the guidelines and then sought input from users on Twitter via a publicly accessible Google Document. There was no limitation on who could provide input and the work was done in a democratic, collaborative fashion. Contributors edited the draft over a period of 1 week (September 12-18, 2020). The primary and secondary authors then revised the draft to make it more concise. The guidelines and manuscript were then distributed to the contributors for edits and adopted by the group. All contributors were given the opportunity to serve as coauthors on the publication and were told upfront that authorship would depend on whether they were able to document the ways in which they met the 4 International Committee of Medical Journal Editors authorship criteria. RESULTS: We developed 2 sets of guidelines: Guidelines for Listing All Social Media Scholarship Under Public Scholarship (in Research/Scholarship Section of CV) and Guidelines for Listing Social Media Scholarship Under Research, Teaching, and Service Sections of CV. Institutions can choose which set fits their existing CV format. CONCLUSIONS: With more uniformity, scholars can better represent the full scope and impact of their work. These guidelines are not intended to dictate how individual institutions should weigh social media contributions within promotion and tenure cases. Instead, by providing an initial set of guidelines, we hope to provide scholars and their institutions with a common format and language to document social media scholarship.

RESUMO

PURPOSE: To determine the risk factors associated with progression to blindness from primary open-angle glaucoma (POAG) in an African-American population. METHODS: This study examined 2119 patients enrolled in the Primary Open-Angle African-American Glaucoma Genetics (POAAGG) study. A total of 59 eyes were identified as legally blind as a result of POAG (cases) and were age-and sex-matched to 59 non-blind eyes with glaucoma (controls). Chart reviews were performed to record known and suspected risk factors. RESULTS: Cases were diagnosed with POAG at an earlier age than controls (p = 0.005). Of the 59 eyes of cases, 16 eyes (27.1%) presented with blindness at diagnosis. Cases had worse visual acuity (VA) at diagnosis (p < 0.0001), with VA worse than 20/40 conferring a 27 times higher risk of progression to blindness (p = 0.0005). Blind eyes also demonstrated more visual field defects (p = 0.01), higher pre-treatment intraocular pressure (IOP; p < 0.0001), and higher cup-to-disc ratio (p = 0.006) at diagnosis. IOP was less controlled in cases, and those with IOP ≥21 mmHg at more than 20% of follow-up visits were 73 times more likely to become blind (p < 0.0001). Cases missed a greater number of appointments per year (p = 0.003) and had non-adherence issues noted in their charts more often than controls (p = 0.03). However, other compliance data did not significantly differ between groups. CONCLUSION: Access to care, initial VA worse than 20/40, and poor control of IOP were the major risk factors associated with blindness from POAG. Future studies should examine earlier, more effective approaches to glaucoma screening as well as the role of genetics in these significantly younger patients who progress to blindness.

RESUMO

OBJECTIVE: To identify the major risk factors for primary open-angle glaucoma (POAG) in individuals of African descent. METHODS: We searched PubMed for relevant articles, with results spanning April 1947 to present. All abstracts were reviewed and, where relevant to POAG and race, articles were catalogued and analyzed. Additional sources were identified through citations in articles returned by our search. RESULTS: Numerous potential POAG risk factors were identified and organized into categories by demographics (age, sex, and skin color), lifestyle choices (smoking, alcohol), comorbidities (hypertension, diabetes, and obesity), ophthalmic findings (eye structure, central corneal thickness, corneal hysteresis, elevated intraocular pressure, myopia, cataract, and vascular abnormalities), family history, socioeconomic status, and adherence. Older age, male sex, lower central corneal thickness, decreased corneal hysteresis, elevated intraocular pressure, myopia, vascular abnormalities, and positive family history were definitively associated with increased risk of POAG. CONCLUSIONS: Individuals at greatest risk for POAG should be screened by an ophthalmologist to allow earlier detection and to slow disease progression. Further studies on the genetics of the disease will provide more insight into underlying pathologic mechanisms and could lead to improved therapeutic interventions. Continued research in urban areas with large populations of blacks is especially needed.

RESUMO

PURPOSE: To describe the baseline characteristics of the Primary Open-Angle African American Glaucoma Genetics (POAAGG) study cohort, the largest African American population with primary open-angle glaucoma (POAG) recruited at a single institution (University of Pennsylvania [UPenn], Department of Ophthalmology, Scheie Eye Institute) to date. DESIGN: Population-based, cross-sectional, case-control study. PARTICIPANTS: A total of 2520 African American subjects aged 35 years or more who were recruited from the greater Philadelphia, Pennsylvania area. METHODS: Each subject underwent a detailed interview and eye examination. The interview assessed demographic, behavioral, medical, and ocular risk factors. Current ZIP codes surrounding UPenn were recorded and US census data were queried to infer socioeconomic status. The eye examination included measurement of visual acuity (VA) and intraocular pressure, and a detailed anterior and posterior segment examination, including gonioscopy, dilated fundus and optic disc examination, visual fields, stereo disc photography, optical coherence tomography, and measurement of central corneal thickness. MAIN OUTCOME MEASURES: The baseline characteristics of gender, age, and glaucoma diagnosis were collected. Body mass index (BMI), hypertension, diabetes, alcohol and tobacco use, ocular conditions (including blindness, cataract, nonproliferative diabetic retinopathy, and age-related macular degeneration), and use of ocular medication and surgery were examined. Median population density, income, education level, and other socioeconomic measures were determined for the study cohort. RESULTS: Of the 2520 African Americans recruited to the POAAGG study to date, 2067 (82.0%), including 807 controls and 1260 POAG cases, met all inclusion criteria and completed the detailed clinical ocular examination. Cases were more likely to have a lower BMI (P < 0.01) and report a history of blindness (VA of ≤20/200; P < 0.001), whereas controls were more likely to have diabetes (P < 0.001), have nonproliferative diabetic retinopathy (P = 0.02), and be female (P < 0.001). Study participants were drawn largely from predominantly African American neighborhoods of low income, high unemployment, and lower education surrounding UPenn. CONCLUSIONS: The POAAGG study has currently recruited more than 2000 African Americans eligible for a POAG genetics study. Blindness and low BMI were significantly associated with POAG. This population was predominantly recruited from neighborhoods whose population income exists at or near the federal poverty level.

RESUMO

Primary open-angle glaucoma (POAG) is a major cause of blindness and results from irreversible retinal ganglion cell damage and optic nerve degeneration. In the United States, POAG is most prevalent in African-Americans. Mitochondrial genetics and dysfunction have been implicated in POAG, and potentially pathogenic sequence variations, in particular novel transversional base substitutions, are reportedly common in mitochondrial genomes (mtDNA) from POAG patient blood. The purpose of this study was to ascertain the spectrum of sequence variation in mtDNA from African-American POAG patients and determine whether novel nonsynonymous, transversional or other potentially pathogenic sequence variations are observed more commonly in POAG cases than controls. mtDNA from African-American POAG cases (n = 22) and age-matched controls (n = 22) was analyzed by deep sequencing of a single 16,487 base pair PCR amplicon by Ion Torrent, and candidate novel variants were validated by Sanger sequencing. Sequence variants were classified and interpreted using the MITOMAP compendium of polymorphisms. 99.8% of the observed variations had been previously reported. The ratio of novel variants to POAG cases was 7-fold lower than a prior estimate. Novel mtDNA variants were present in 3 of 22 cases, novel nonsynonymous changes in 1 of 22 cases and novel transversions in 0 of 22 cases; these proportions are significantly lower (p<.0005, p<.0004, p<.0001) than estimated previously for POAG, and did not differ significantly from controls. Although it is possible that mitochondrial genetics play a role in African-Americans' high susceptibility to POAG, it is unlikely that any mitochondrial respiratory dysfunction is due to an abnormally high incidence of novel mutations that can be detected in mtDNA from peripheral blood.

RESUMO

We report a method for the synthesis of soluble, well-defined, azide-functionalized polypeptides via living polymerization of new azide-containing amino acid N-carboxyanhydride (NCA) monomers. Homo and diblock azidopolypeptides were prepared with controlled segment lengths using (PMe3)4Co initiator and were subsequently modified by reaction with functional alkyne reagents. The azide groups were found to be quantitatively converted to the corresponding triazole derivatives, and the functionalized polymers were obtained in high yield. This methodology provides a facile and straightforward method for preparation of functional and side-chain reactive, high molecular weight polypeptides.

RESUMO

Here, we report a method for synthesis of cylindrical copolypeptide brushes via N-carboxyanhydride (NCA) polymerization utilizing a new tandem catalysis approach that allows preparation of brushes with controlled segment lengths in a straightforward, one-pot procedure requiring no intermediate isolation or purification steps. To obtain high-density brush copolypeptides, we used a "grafting from" approach where alloc-α-aminoamide groups were installed onto the side chains of NCAs to serve as masked initiators. These groups were inert during cobalt-initiated NCA polymerization and gave allyloxycarbonyl-α-aminoamide-substituted polypeptide main chains. The alloc-α-aminoamide groups were then activated in situ using nickel to generate initiators for growth of side-chain brush segments. This use of stepwise tandem cobalt and nickel catalysis was found to be an efficient method for preparation of high-chain-density, cylindrical copolypeptide brushes, where both the main chains and side chains can be prepared with controlled segment lengths.

RESUMO

Several heterocycles such as furanones, pyrrolones, and indolizines, which are of pharmacological importance, are easily accessed via the Pt(II)-catalyzed heterocyclization/1,2-migration of propargylic ketols or hydroxy imine derivatives. This method sidesteps the challenges of traditional heteroaromatic oxygenation strategies such as regioselectivity and functional group tolerance in the syntheses of these heterocycles.

RESUMO

PURPOSE: The purpose of this study was to determine various aspects of the research experiences in postgraduate and residency training programs in pediatric dentistry. METHODS: A survey was developed and sent to all directors of postgraduate and residency training programs in pediatric dentistry. The survey consisted of 21 items on various topics related to research experiences of the postgraduate students and residents. The items varied in structure, but most contained response sets deemed appropriate for the intent of the question. The directors were asked to complete the survey and return the questionnaire in a self-addressed stamped envelope within a 3-week period. If a program did not respond within 6 weeks, a follow-up survey was sent. The response sets were collated and analyzed with descriptive and nonparametric statistics. RESULTS: Forty of 55 programs responded with usable data sets. All reporting programs indicated that research experiences occur for residents and all have access to statistical assistance. Eighty-seven percent devote clinical hours to student research and 50% of the students share data or protocols. Only a minority (7%) of programs has not published student research in the last 5 years. Interference with revenue-generating clinic times (45%), lack of faculty understanding/interest in research (40%), and lack of financial resources (32%) were the 3 major obstacles for postgraduate research. CONCLUSIONS: Despite research being accomplished in postgraduate programs in pediatric dentistry, variability in key factors (eg, devoted research time) is common among programs. The impact of this variability on the profession and its advancement of scientific endeavors are unknown.
