Textual analysis of internal medicine residency personal statements: themes and gender differences
Context Applicants to US residency training programmes are required to submit a personal statement, the content of which is flexible but often requires them to describe their career goals and aspirations. Despite their importance, no systematic research has explored common themes and gender differences inherent to these statements. Objectives This study was conducted to analyse US applicants’ Electronic Residency Application Service (ERAS) personal statements using two automated textual analysis programs, and to assess for common themes and gender-associated differences. Methods A retrospective cohort study of 2138 personal statements (containing 1 485 255 words) from candidates from 377 national and international medical schools applying to US internal medicine (IM) residency programmes through ERAS was conducted. A mathematical analysis of text segments using a recursive algorithm was performed; two different specifications of the text segments were used to conduct an internal validation. Results Five statistically significant thematic classes were identified through independent review by the researchers. These were best defined as referring to: the appeal of the residency programme; memorable patients; health care as public policy; research and academia, and family inspiration. Some themes were common to all applications. However, important gender-specific differences were identified. Notably, men were more likely to describe personal attributes and to self-promote, whereas women more frequently expressed the communicative and team-based aspects of doctoring. The results were externally validated using a second software program. Although these data comprise part of the national pool, they represent applicants to a single specialty at a single institution. Conclusions By applying textual analysis to material derived from a national cohort, we identified common narrative themes in the personal statements of future US physicians, noting differences between men and women. Together, these data provide novel insight into the dominant discourse of doctoring in this generation of students applying for further training in US IM residency programmes, and depict a diverse group of applicants with multiple motivations, desires and goals. Furthermore, differences seen between men and women add to the growing understanding of bias in medical education. Training programmes may benefit by adapting curricula to foster such diverse interests

Geographical Survey of the Mycobiome and Microbiome of Southern California Glassy-winged Sharpshooters
The glassy-winged sharpshooter, Homalodisca vitripennis Germar, is an invasive xylem-feeding leafhopper with a devastating economic impact on California agriculture through transmission of the plant pathogen, Xylella fastidiosa . While studies have focused on X. fastidiosa or known symbionts of H. vitripennis , little work has been done at the scale of the microbiome (the bacterial community) or mycobiome (the fungal community). Here we characterize the mycobiome and the microbiome of H. vitripennis across Southern California and explore correlations with captivity and host insecticide-resistance status. Using high-throughput sequencing of the ribosomal internal transcribed spacer (ITS1) region and the 16S rRNA gene to profile the mycobiome and microbiome, respectively, we found that while the H. vitripennis mycobiome significantly varied across Southern California, the microbiome did not. We also observed a significant difference in both the mycobiome and microbiome between captive and wild H. vitripennis . Finally, we found that the mycobiome, but not the microbiome, was correlated with insecticide-resistance status in wild H. vitripennis . This study serves as a foundational look at the H. vitripennis mycobiome and microbiome across Southern California. Future work should explore the putative link between microbes and insecticide-resistance status and investigate whether microbial communities should be considered in H. vitripennis management practices

Geographical survey of the mycobiome and microbiome of Southern California glassy-winged sharpshooters.
The glassy-winged sharpshooter, Homalodisca vitripennis Germar, is an invasive xylem-feeding leafhopper with a devastating economic impact on California agriculture through transmission of the plant pathogen, Xylella fastidiosa. While studies have focused on X. fastidiosa or known symbionts of H. vitripennis, little work has been done at the scale of the microbiome (the bacterial community) or mycobiome (the fungal community). Here, we characterize the mycobiome and the microbiome of H. vitripennis across Southern California and explore correlations with captivity and host insecticide resistance status. Using high-throughput sequencing of the ribosomal internal transcribed spacer 1 region and the 16S rRNA gene to profile the mycobiome and microbiome, respectively, we found that while the H. vitripennis mycobiome significantly varied across Southern California, the microbiome did not. We also observed a significant difference in both the mycobiome and microbiome between captive and wild H. vitripennis. Finally, we found that the mycobiome, but not the microbiome, was correlated with insecticide resistance status in wild H. vitripennis. This study serves as a foundational look at the H. vitripennis mycobiome and microbiome across Southern California. Future work should explore the putative link between microbes and insecticide resistance status and investigate whether microbial communities should be considered in H. vitripennis management practices. IMPORTANCE The glassy-winged sharpshooter is an invasive leafhopper that feeds on the xylem of plants and transmits the devastating pathogen, Xylella fastidiosa, resulting in significant economic damage to California's agricultural system. While studies have focused on this pathogen or obligate symbionts of the glassy-winged sharpshooter, there is limited knowledge of the bacterial and fungal communities that make up its microbiome and mycobiome. To address this knowledge gap, we explored the composition of the mycobiome and the microbiome of the glassy-winged sharpshooter across Southern California and identified differences associated with geography, captivity, and host insecticide resistance status. Understanding sources of variation in the microbial communities associated with the glassy-winged sharpshooter is an important consideration for developing management strategies to control this invasive insect. This study is a first step toward understanding the role microbes may play in the glassy-winged sharpshooter's resistance to insecticides

Association between physician age and patterns of end‐of‐life care among older Americans
BackgroundEnd-of-life (EOL) care patterns may differ by physician age given differences in how physicians are trained or changes associated with aging. We sought to compare patterns of EOL care delivered to older Americans according to physician age.MethodsWe conducted a cross-sectional study of a 20% sample of Medicare fee-for-service beneficiaries aged ≥66 years who died in 2016-2019 (n = 487,293). We attributed beneficiaries to the physician who had >50% of primary care visits during the last 6 months of life. We compared beneficiary-level outcomes by physician age (<40, 40-49, 50-59, or ≥60) in two areas: (1) advance care planning (ACP) and palliative care; and (2) high-intensity care at the EOL.ResultsBeneficiaries attributed to younger physicians had slightly higher proportions of billed ACP (adjusted proportions, 17.1%, 16.1%, 15.5%, and 14.0% for physicians aged <40, 40-49, 50-59, and ≥60, respectively; p-for-trend adjusted for multiple comparisons <0.001) and palliative care counseling or hospice use in the last 180 days of life (64.5%, 63.6%, 61.9%, and 60.8%; p-for-trend <0.001). Similarly, physicians' younger age was associated with slightly lower proportions of emergency department visits (57.4%, 57.0%, 57.4%, and 58.1%; p-for-trend <0.001), hospital admissions (51.2%, 51.1%, 51.4%, and 52.1%; p-for-trend <0.001), intensive care unit admissions (27.8%, 27.9%, 28.2%, and 28.3%; p-for-trend = 0.03), or mechanical ventilation or cardiopulmonary resuscitation (14.2, 14.9%, 15.2%, and 15.3%; p-for-trend <0.001) in the last 30 days of life, and in-hospital death (20.2%, 20.6%, 21.3%, and 21.5%; p-for-trend <0.001).ConclusionsWe found that differences in patterns of EOL care between beneficiaries cared for by younger and older physicians were small, and thus, not clinically meaningful. Future research is warranted to understand the factors that can influence patterns of EOL care provided by physicians, including initial and continuing medical education

Signature morphoelectric properties of diverse GABAergic interneurons in the human neocortex
Human cortex transcriptomic studies have revealed a hierarchical organization of γ-aminobutyric acid-producing (GABAergic) neurons from subclasses to a high diversity of more granular types. Rapid GABAergic neuron viral genetic labeling plus Patch-seq (patch-clamp electrophysiology plus single-cell RNA sequencing) sampling in human brain slices was used to reliably target and analyze GABAergic neuron subclasses and individual transcriptomic types. This characterization elucidated transitions between PVALB and SST subclasses, revealed morphological heterogeneity within an abundant transcriptomic type, identified multiple spatially distinct types of the primate-specialized double bouquet cells (DBCs), and shed light on cellular differences between homologous mouse and human neocortical GABAergic neuron types. These results highlight the importance of multimodal phenotypic characterization for refinement of emerging transcriptomic cell type taxonomies and for understanding conserved and specialized cellular properties of human brain cell types.</p
