The choice between hemodiafiltration (HDF) or high-flux hemodialysis (HD) to treat end-stage kidney disease remains a matter of debate. duration recovery time after treatment has been associated with mortality, affects quality life, and may therefore be important in informing patient choice. We aimed establish whether is influenced by HDF HD.Randomized patient-blinded crossover trial.100 patients were enrolled from 2 satellite dialysis units Glasgow, United Kingdom.8 weeks HD followed 8...
People experiencing homelessness are at increased risk of coronavirus disease 2019 (COVID-19), but little is known about specific factors for infection within homeless shelters.We performed widespread severe acute respiratory syndrome 2 (SARS-CoV-2) polymerase chain reaction testing and collected factor information all shelters in Chicago with least 1 reported case COVID-19 (n = 21). Multivariable, mixed-effects log-binomial models were built to estimate adjusted prevalence ratios (aPRs)...
Monovalent booster/additional doses of COVID-19 vaccines were first authorized in August 2021 the United States. We evaluated real-world effectiveness receipt a monovalent dose vaccine compared with receiving primary series without dose. Cohorts individuals after complete identified 2 administrative insurance claims databases (Optum, CVS Health) supplemented state immunization information system data between and March 2022. Individuals but one-to-one matched to boosted on calendar date,...
Abstract Among solid organ transplant recipients taking belatacept, 15% developed invasive fungal diseases. The most common diseases were aspergillosis (56%) and candidiasis (22%). infected cohort was more likely to receive basiliximab, undergo lung transplantation, or identify as White. Higher rates of seen in this than previously reported.
Abstract Background Field epidemiology training programs (FETPs) have trained field epidemiologists who strengthen global capacities for surveillance and response to public health threats. We describe how FETP residents graduates contributed COVID-19 preparedness globally. Methods conducted a cross-sectional survey of FETPs between March 13 April 15, 2020 understand or were contributing activities. The tool was structured around the eight Pillars World Health Organization’s (WHO) Strategic...
Background. Since May 2022, a large global outbreak of human mpox has predominantly affected men who have sex with men. The strain responsible, Clade IIb, mutated significantly from precursors originating the 2017-18 in Nigeria. Immunity to smallpox, another orthopoxvirus, via previous infection or vaccination provides life-long immunity. However, since 2022 outbreak, recent clusters case been described persons presumed immunity through vaccination. We describe epidemiological and clinical...
Abstract Background Education in infectious disease (ID) is a critical part of an internal medicine curriculum. As the consult service typically high volume and busy, residents other trainees were often not receiving adequate training less common conditions or didactic that may be relevant for their future practice board exams. Our Quality Improvement project sought to improve medical students through integration high-yield lecture services given on Adult ID service.Figure 1:Pre/Post Test...
Abstract Background The human microbiome has been linked to important clinical outcomes, including postoperative infection. Loss of diversity associated with drug resistant organism colonization, infection, immune defenses, epithelial barrier integrity, and death. microbiome’s role in infection among heart transplant (HT) recipients remains poorly understood.Table 1Clinical CharacteristicsTable 1 Clinical Characteristics: Characteristics noted by number percent or mean Standard Deviation...
Abstract Background Since 8/31/2022, 39,998 new arrivals have made Chicago their home, with the majority coming from Latin America. Epidemiological diversity in these countries of origin as well infection risks encountered on journey to US resulted increased requests for advice Infectious Diseases (ID) specialists and a need rapid education clinicians, raising question how best address this knowledge gap. Initial Triage Algorithm Clinicians are directed algorithm when first presented febrile...
With data from 2 US claims databases (Optum, CVS Health) supplemented with Immunization Information System COVID-19 vaccine records, we evaluated overall and time-specific effectiveness (VE) of an initial primary series for 3 monovalent vaccines—BNT162b2, mRNA-1273, JNJ-7836735—in adults (18-64 years). Vaccinated individuals were matched to unvaccinated comparators, estimated VE against any medically diagnosed hospital/emergency department (ED)-diagnosed COVID-19. Additionally, by era...
5072 Background: Over the past 6 years, intensification of androgen deprivation therapy (ADT) with docetaxel (DOC) and novel hormonal therapies (NHT) [abiraterone, enzalutamide, apalutamide], has been shown to improve survival outcomes in men mCSPC. This study assessed real-world utilization effective combination as 1L treatment insured pts U.S. Methods: retrospective used Optum health insurance claims database, which includes pt data from both commercially Medicare Advantage populations....

Premature cardiovascular disease in patients with chronic kidney (CKD) is not explained by traditional risk factors and oxidative stress may contribute via endothelial vascular dysfunction. We investigated the effect of ascorbic acid on function CKD compared controls hypertension (HTN). A crossover study intravenous saline was conducted. Biomarkers were measured, while pulse wave analysis brachial flow-mediated dilatation performed to assess large artery function. Twenty HTN 30 Stages 3–5...
Background: Personal health information, including diagnoses and hospital admissions, is routinely collected in administrative databases. Patients enrolling on clinical trials consent to separate collection storage of their personal information. We evaluated patient preferences for linking long-term data from databases with trials. Methods: Adults cancer attending outpatient clinics at 3 Ontario hospitals were surveyed about willingness, when faced the hypothetical scenario participating a...

Importance Safety and effectiveness studies of COVID-19 vaccines are being conducted using clinical data, including administrative claims. However, claims data only partially capture administered vaccine doses for numerous reasons, such as vaccination at sites that do not generate reimbursement. Objective To evaluate the extent to which Immunization Information Systems (IIS) linked enhances claims-based a commercially insured population estimate magnitude misclassification vaccinated...
