RESUMO
ABSTRACT: Despite the growing popularity of Physical Medicine & Rehabilitation (PM&R) as a specialty among medical students, meaningful experiences and mentorship can be challenging to obtain and may significantly vary depending on opportunities available to interact with physiatrists. This study explores the association between the geographic proximity of PM&R residency programs to medical schools and the match rate of medical students into PM&R from 2019 to 2021. Data on US medical schools, graduates, and PM&R residency programs were collected from publicly available sources, and a sample of 1,193 PM&R residents from US medical schools was analyzed using a one-sample proportion test. The proportion of PM&R residents originating from medical schools with PM&R residency programs in the same metropolitan area was significantly greater than the corresponding proportion of expected residents based on medical school graduates, even when controlling for medical school affiliations with PM&R residency programs. These findings suggest that exposure and opportunities provided by PM&R residency programs may influence nearby medical students and that expanding residency programs into geographic regions without existing PM&R programs may foster interest and promote growth in the field of physiatry.
RESUMO
Carbapenem-resistant Enterobacterales (CRE) are an urgent public health threat. Genomic sequencing is an important tool for investigating CRE. Through the Division of Healthcare Quality Promotion Sentinel Surveillance system, we collected CRE and carbapenem-susceptible Enterobacterales (CSE) from nine clinical laboratories in the USA from 2013 to 2016 and analysed both phenotypic and genomic sequencing data for 680 isolates. We describe the molecular epidemiology and antimicrobial susceptibility testing (AST) data of this collection of isolates. We also performed a phenotype-genotype correlation for the carbapenems and evaluated the presence of virulence genes in Klebsiella pneumoniae complex isolates. These AST and genomic sequencing data can be used to compare and contrast CRE and CSE at these sites and serve as a resource for the antimicrobial resistance research community.

The Onchocerca lupi nematode infects dogs, cats, and humans, but whether it can be spread by coyotes has been unknown. We conducted surveillance for O. lupi nematode infection in coyotes in the southwestern United States. We identified multiple coyote populations in Arizona and New Mexico as probable reservoirs for this species.

Altered intestinal microbiota is associated with systemic and intestinal diseases, such as inflammatory bowel disease (IBD). Dysbiotic microbiota with enhanced proinflammatory capacity is characterized by depletion of anaerobic commensals, increased proportion of facultatively anaerobic bacteria, as well as reduced diversity and stability. In this study, we developed a high-throughput in vitro screening assay to isolate intestinal commensal bacteria with anti-inflammatory capacity from a healthy fecal microbiota transplantation donor. Freshly isolated gut bacteria were screened for their capacity to attenuate Escherichia coli lipopolysaccharide (LPS)-induced interleukin 8 (IL-8) release from HT-29 cells. The screen yielded a number of Bacteroides and Parabacteroides isolates, which were identified as P. distasonis, B. caccae, B. intestinalis, B. uniformis, B. fragilis, B. vulgatus and B. ovatus using whole genome sequencing. We observed that a cell-cell contact with the epithelium was not necessary to alleviate in vitro inflammation as spent culture media from the isolates were also effective and the anti-inflammatory action did not correlate with the enterocyte adherence capacity of the isolates. The anti-inflammatory isolates also exerted enterocyte monolayer reinforcing action and lacked essential genes to synthetize hexa-acylated, proinflammatory lipid A, part of LPS. Yet, the anti-inflammatory effector molecules remain to be identified. The Bacteroides strains isolated and characterized in this study have potential to be used as so-called next-generation probiotics.

The full geographic range of coccidioidomycosis is unknown, although it is most likely expanding with environmental change. We report an apparently autochthonous coccidioidomycosis patient from Spokane, Washington, USA, a location to which Coccidioides spp. are not known to be endemic.
