UNASSIGNED: Hyperkalemia is a prevalent electrolyte disorder related to elevated serum potassium levels, resulting in diverse abnormal electrocardiographic findings and associated clinical signs and symptoms, often necessitating specific treatment. However, in some patients, these abnormal findings may not be present on the electrocardiogram even in elevated serum potassium levels. This study aims to identify electrocardiographic abnormalities related to the severity of hyperkalemia and the clinical outcomes in an emergency department in southwestern Colombia.
UNASSIGNED: This is a retrospective cross-sectional descriptive study. We described the electrocardiographic findings, clinical characteristics, treatment, and outcomes related to the degrees of hyperkalemia. The potential association between the severity of hyperkalemia and electrocardiographic findings was evaluated.
UNASSIGNED: A total of 494 patients were included. The median of the potassium level was 6.6 mEq/L. Abnormal electrocardiographic findings were reported in 61.5% of the cases. Mild and severe hyperkalemia groups reported abnormalities in 59.9% and 61.2%, respectively. The most common electrocardiography abnormalities were the peaked T wave 36.2%, followed by wide QRS 83 (16.8%). Only 1.4% of patients had adverse outcomes. The abnormal findings were registered in 61.5%. Mortality was 11.9%. The peaked T wave was the most common finding across different levels of hyperkalemia severity.
UNASSIGNED: High serum potassium levels are related with abnormal ECG. However, patients with different degrees of hyperkalemia could not describe abnormal ECG findings. In a high proportion of patients with renal chronic disease and hyperkalemia, the abnormalities in the ECG could be minimal or absent.

BACKGROUND: Among doctors in the United Kingdom, there is growing sentiment regarding delaying specialist training, emigrating to practice medicine abroad, or leaving the profession altogether. This trend may have substantial implications for the future of the profession in the United Kingdom. The extent to which this sentiment is also present in the medical student population is not well understood.
OBJECTIVE: Our primary outcome is to determine current medical students\' career intentions after graduation and upon completing the foundation program and to establish the motivations behind these intentions. Secondary outcomes include determining which, if any, demographic factors alter the propensity to pursue different career paths available to a medical graduate, determining which specialties medical students plan on pursuing, and understanding current views on the prospect of working in the National Health Service (NHS).
METHODS: The Ascertaining the Career Intentions of Medical Students (AIMS) study is a national, multi-institution, and cross-sectional study in which all medical students at all medical schools in the United Kingdom are eligible to participate. It was administered via a novel, mixed methods, and web-based questionnaire and disseminated through a collaborative network of approximately 200 students recruited for this purpose. Both quantitative and thematic analyses will be performed.
RESULTS: The study was launched nationally on January 16, 2023. Data collection was closed on March 27, 2023, and data analysis has commenced. The results are expected to be available later in the year.
CONCLUSIONS: Doctors\' career satisfaction within the NHS is a well-researched topic; however, there is a shortage of high-powered studies that are able to offer insight into medical students\' outlook on their future careers. It is anticipated that the results of this study will bring clarity to this issue. Identified areas of improvement in medical training or within the NHS could be targeted to improve doctors\' working conditions and help retain medical graduates. Results may also aid future workforce-planning efforts.

To field test the Disadvantaged Populations eGFR Epidemiology (DEGREE) protocol, outdoor point-of-care (POC) testing for serum creatinine, and a new risk factor module on chronic kidney disease of undetermined origin (CKDu) in U.S. outdoor Hispanic workers.
Fifty workers were interviewed in Houston (TX). DEGREE and CKDu questionnaires were completed indoors. Anthropometrics and paired blood samples for POC and laboratory assay were completed outdoors over two periods (November-December 2017, April-May 2018).
Administration of DEGREE and CKDu questionnaires averaged 10 and 5 min, respectively, with all questions easily understood. We observed high correlations between POC and IDMS creatinine (r = 0.919) and BUN (r = 0.974). The POC device would disable testing when outdoor temperatures were above 85 °F or below 65 °F; this was adjustable.
Implementation of DEGREE and the new CKDu module was straightforward and well understood. The POC device performed well in the field, with some adjustment in methods when temperature readings were out of range.

OBJECTIVEThe position of neurosurgery department chair undergoes constant evolution as the health care landscape changes. The authors\' aim in this paper was to characterize career attributes of neurosurgery department chairs in order to define temporal trends in qualities being sought in neurosurgical leaders. Specifically, they investigated the hypothesis that increased qualifications in the form of additional advanced degrees and research acumen are becoming more common in recently hired chairs, possibly related to the increased complexity of their role.METHODSThe authors performed a retrospective study in which they collected data on 105 neurosurgeons who were neurosurgery department chairs as of December 31, 2016, at accredited academic institutions with a neurosurgery residency program in the United States. Descriptive data on the career of neurosurgery chairs, such as the residency program attended, primary subspecialty focus, and age at which they accepted their position as chair, were collected.RESULTSThe median age and number of years in practice postresidency of neurosurgery chairs on acceptance of the position were 47 years (range 36-63 years) and 14 years (range 6-33 years), respectively, and 87% (n = 91) were first-time chairs. The median duration that chairs had been holding their positions as of December 31, 2016, was 10 years (range 1-34 years). The most common subspecialties were vascular (35%) and tumor/skull base (27%), although the tendency to hire from these specialties diminished over time (p = 0.02). More recently hired chairs were more likely to be older (p = 0.02), have more publications (p = 0.007), and have higher h-indices (p < 0.001) at the time of hire. Prior to being named chair, 13% (n = 14) had a PhD, 4% (n = 4) had an MBA, and 23% (n = 24) were awarded a National Institutes of Health R01 grant, tendencies that were stable over time (p = 0.09-0.23), although when additional degrees were analyzed as a binary variable, chairs hired in 2010 or after were more likely to have an MBA and/or PhD versus those hired before 2010 (26% vs 10%, p = 0.04). The 3 most common residency programs attended by the neurosurgery chairs were Massachusetts General Hospital (n = 8, 8%), University of California, San Francisco (n = 8, 8%), and University of Michigan (n = 6, 6%). Most chairs (n = 63, 61%) attended residency at the institution and/or were staff at the institution before they were named chair, a tendency that persisted over time (p = 0.86).CONCLUSIONSMost neurosurgery department chairs matriculated into the position before the age of 50 years and, despite selection processes usually involving a national search, most chairs had a previous affiliation with the department, a phenomenon that has been relatively stable over time. In recent years, a large increase has occurred in the proportion of chairs with additional advanced degrees and more extensive research experience, underscoring how neurosurgical leadership has come to require scientific skills and the ability to procure grants, as well as the financial skills needed to navigate the ever-changing financial health care landscape.
