A framework for monitoring RSV prevention product effectiveness in the United States.

During 2023, the Centers for Disease Control and Prevention (CDC) recommended the first respiratory syncytial virus (RSV) immunizations intended for widespread use in the United States to prevent severe RSV illness in infants and older adults. CDC, in collaboration with federal, public health, and academic partners, is conducting evaluations of real-world effectiveness of recommended RSV immunization products in the United States. Similar frameworks for evaluation are being applied to RSV vaccines and nirsevimab, a long-acting preventative monoclonal antibody, to estimate product effectiveness.

Assessments and observations of infection prevention and control practices in US outpatient hemodialysis facilities, 2015-2018: important opportunities for improvement.

Infections cause substantial morbidity and mortality among patients receiving care in outpatient hemodialysis facilities. We describe comprehensive infection prevention assessments by US public health departments using standardized interview and observation tools. Results demonstrated how facility layouts can undermine infection prevention and that clinical practices often fall short of policies.

Intravenous Antimicrobial Starts among Hemodialysis Patients in the National Healthcare Safety Network Dialysis Component, 2016-2020.

NHSN total IV antimicrobial start rates for patients on hemodialysis decreased from 2016 to 2020, but rates unsupported by NHSN surveillance documentation did not. There were 80% of reporting hemodialysis facilities that had ≥1 unsupported IV antimicrobial start, and the fraction of facilities with unsupported starts increased yearly. Accurate reporting and timely review of antimicrobial data is critical to understanding prescribing trends and practices in hemodialysis facilities.

SARS-CoV-2 Infections among Vaccinated Patients on Maintenance Dialysis, January 1-August 31, 2021, United States.

Dialysis facilities voluntarily reported severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in vaccinated dialysis patients detected between January 1, 2021, and August 31, 2021, to the Centers for Disease Control and Prevention.Among 4087 patients reported, most were symptomatic, a third required hospitalization, and 9% died within 30 days of diagnosis.Monitoring SARS-CoV-2 infections and outcomes among vaccinated people on dialysis provides valuable insight into this population.

Outcomes at least 90 days since onset of myocarditis after mRNA COVID-19 vaccination in adolescents and young adults in the USA: a follow-up surveillance study.

Background: Data on medium-term outcomes in indivduals with myocarditis after mRNA COVID-19 vaccination are scarce. We aimed to assess clinical outcomes and quality of life at least 90 days since onset of myocarditis after mRNA COVID-19 vaccination in adolescents and young adults.

Methods: In this follow-up surveillance study, we conducted surveys in US individuals aged 12-29 years with myocarditis after mRNA COVID-19 vaccination, for whom a report had been filed to the Vaccine Adverse Event Reporting System between Jan 12 and Nov 5, 2021.

Dialysis Water Supply Faucet as Reservoir for Carbapenemase-Producing Pseudomonas aeruginosa.

During June 2017-November 2019, a total 36 patients with carbapenem-resistant Pseudomonas aeruginosa harboring Verona-integron-encoded metallo-β-lactamase were identified in a city in western Texas, USA. A faucet contaminated with the organism, identified through environmental sampling, in a specialty care room was the likely source for infection in a subset of patients.

Clinical Course of SARS-CoV-2 Infection in Adults with ESKD Receiving Outpatient Hemodialysis.

Background: Patients with ESKD on maintenance dialysis receive dialysis in common spaces with other patients and have a higher risk of severe SARS-CoV-2 infections. They may have persistently or intermittently positive SARS-CoV-2 RT-PCR tests after infection. We describe the clinical course of SARS-CoV-2 infection and the serologic response in a convenience sample of patients with ESKD to understand the duration of infectivity.

Assessment of Provision of COVID-19 Vaccination in Dialysis Clinics and Patient Vaccination Coverage.

This quality improvement study assesses COVID-19 vaccination in dialysis clinics, vaccination coverage, and disparities from December 1, 2020, to June 13, 2021.

Pulmonary and Critical Care Considerations for e-Cigarette, or Vaping, Product Use-Associated Lung Injury.

Background: In 2019, the United States experienced a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI). More than one-half of these patients required admission to an ICU.

Research Question: What are the recent literature and expert opinions which inform the diagnosis and management of patients with critical illness with EVALI?

Study Design And Methods: To synthesize information critical to pulmonary/critical care specialists in the care of patients with EVALI, this study examined data available from patients hospitalized with EVALI between August 2019 and January 2020; reviewed the clinical course and critical care experience with those patients admitted to the ICU; and compiled opinion of national experts.

Development and Validation of an Enzyme Immunoassay for Detection and Quantification of SARS-CoV-2 Salivary IgA and IgG.

Oral fluids offer a noninvasive sampling method for the detection of Abs. Quantification of IgA and IgG Abs in saliva allows studies of the mucosal and systemic immune response after natural infection or vaccination. We developed and validated an enzyme immunoassay (EIA) to detect and quantify salivary IgA and IgG Abs against the prefusion-stabilized form of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein expressed in suspension-adapted HEK-293 cells.

Absence of SARS-CoV-2 infections among patients with end-stage renal disease following facility-wide testing in four outpatient hemodialysis facilities.

Facility-wide testing performed at 4 outpatient hemodialysis facilities in the absence of an outbreak or escalating community incidence did not identify new SARS-CoV-2 infections and illustrated key logistical considerations essential to successful implementation of SARS-CoV-2 screening. Facilities could consider prioritizing facility-wide SARS-CoV-2 testing during suspicion of an outbreak in the facility or escalating community spread without robust infection control strategies in place. Being prepared to address operational considerations will enhance implementation of facility-wide testing in the outpatient dialysis setting.

Suggestions for the prevention of Clostridioides difficile spread within outpatient hemodialysis facilities.

Clostridioides difficile infections (CDIs) cause substantial morbidity and mortality. Patients on maintenance hemodialysis are 2 to 2.5 times more likely to develop CDI, with mortality rates 2-fold higher than the general population.

Implementation of an Electronic Catheter Checklist in Outpatient Hemodialysis Facilities: Results of a Pilot Quality Improvement Project.

Background: Performing catheter-care observations in outpatient hemodialysis facilities are one of the CDC's core interventions, which have been proven to reduce bloodstream infections. However, staff have many competing responsibilities. Efforts to increase and streamline the process of performing observations are needed.

Gaps in infection prevention practices for catheter-associated urinary tract infections and central line-associated bloodstream infections as identified by the Targeted Assessment for Prevention Strategy.

Background: Catheter-associated urinary tract infections (CAUTI) and central line-associated bloodstream infections (CLABSI) represent a substantial portion of health care-associated infections (HAIs) reported in the United States. The Targeted Assessment for Prevention Strategy is a quality improvement framework to reduce health care-associated infections. Data from the Targeted Assessment for Prevention Facility Assessments were used to determine common infection prevention gaps for CAUTI and CLABSI.

Enhanced contact investigations for nine early travel-related cases of SARS-CoV-2 in the United States.

Coronavirus disease 2019 (COVID-19), the respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first identified in Wuhan, China and has since become pandemic. In response to the first cases identified in the United States, close contacts of confirmed COVID-19 cases were investigated to enable early identification and isolation of additional cases and to learn more about risk factors for transmission. Close contacts of nine early travel-related cases in the United States were identified and monitored daily for development of symptoms (active monitoring).

Transmission of SARS-CoV-2 Involving Residents Receiving Dialysis in a Nursing Home - Maryland, April 2020.

SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), can spread rapidly in nursing homes once it is introduced (1,2). To prevent outbreaks, more data are needed to identify sources of introduction and means of transmission within nursing homes. Nursing home residents who receive hemodialysis (dialysis) might be at higher risk for SARS-CoV-2 infections because of their frequent exposures outside the nursing home to both community dialysis patients and staff members at dialysis centers (3).

[Molecular markers as risk factors for thyroid cancer].

Thyroid cancer is the most common malignant tumor of the endocrine system. An increase in the incidence of thyroid cancer has been noted over the past decade, mainly due to papillary cancer. The influence of environmental factors, increased availability of medical care, including sensitive diagnostic tests, such as ultrasound and fine - needle aspiration (FNA), can affect the fact of the growth of this incidence.
