We assessed factors associated with increased risk to loss of follow-up with infectious diseases staff in OPAT patients. Discharge to subacute healthcare facilities is strongly associated with loss to follow-up. We did not identify sociodemographic disparities. Poor communication between OPAT providers and subacute healthcare facilities remains a serious issue.

The coronavirus disease 2019 (COVID-19) pandemic has caused more than 675 million confirmed cases and nearly 7 million deaths worldwide [1]. While testing for COVID-19 was initially centered in health care facilities, with required reporting to health departments, it is increasingly being performed in the home with rapid antigen testing [2]. Most at-home tests are self-interpreted and not reported to a provider or health department, which could lead to delayed reporting or underreporting of cases [3]. As such, there is a strong possibility that reported cases may become a less reliable indicator of transmission over time.

BACKGROUND:Long-acting injectable HIV pre-exposure prophylaxis (LAI-PrEP) was approved by the U.S. Food and Drug Administration in December 2021. This initial phase of implementation represents a prime opportunity to ensure equitable LAI-PrEP provision to communities often underrepresented in PrEP care before disparities in access and uptake emerge. Herein, we describe the EquiPrEP Project which utilizes an equity-oriented implementation science framework to optimize LAI-PrEP rollout in an urban safety-net clinic in New York City. METHODS:The primary objectives of this project are to: (1) increase LAI-PrEP initiation overall; (2) increase uptake among groups disproportionately impacted by the HIV epidemic; (3) preserve high PrEP retention while expanding use; and (4) identify barriers and facilitators to LAI-PrEP use. EquiPrEP will enroll 210 PrEP-eligible participants into LAI-PrEP care with planned follow-up for one year. We will recruit from the following priority populations: Black and/or Latine men who have sex with men, Black and/or Latine cisgender women, and transgender women and nonbinary individuals. To evaluate implementation of LAI-PrEP, we will utilize equity-focused iterations of the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework and the Consolidated Framework for Implementation Research (CFIR), in addition to longitudinal surveys and qualitative interviews. DISCUSSION:Novel LAI-PrEP formulations carry tremendous potential to revolutionize the field of HIV prevention. Implementation strategies rooted in equity are needed to ensure that marginalized populations have access to LAI-PrEP and to address the structural factors that hinder initiation and retention in care.

PURPOSE OF REVIEW:The purpose of this review is to summarize recent literature on nontuberculous mycobacteria in water of healthcare systems. Despite improvement in identification techniques and emergence of infection prevention and control programs, nontuberculous mycobacteria remain present in hospital water systems, causing outbreaks and pseudo-outbreaks in healthcare settings. RECENT FINDINGS:Waterborne outbreaks and pseudo-outbreaks of nontuberculous mycobacteria continue to affect hospitals. Improvements in methods of identification and investigation, including MALDI-TOF and whole genome sequencing with evaluation of single nucleotide polymorphisms, have been used successfully in outbreak and pseudo-outbreak investigations. Recent studies have shown control of outbreaks in immunocompromised patients through the use of sterile water for consumption, as well as control of pseudo-outbreaks by using sterile water for procedures. Construction activities have been implicated in outbreaks and pseudo-outbreaks of nontuberculous mycobacteria. Water management programs are now required by the Joint Commission, which will likely improve water risk mitigation. SUMMARY:Improvement in detection and identification of nontuberculous mycobacteria has led to increasing recognition of waterborne outbreaks and pseudo-outbreaks. Water management programs are of vital importance in infection prevention.

Background/UNASSIGNED:, known to colonize all parts of the cotton plant. Only one prior case report has suggested cotton fever as a potential risk factor of infective endocarditis (IE). Case summary/UNASSIGNED:IE with bilateral septic pulmonary emboli. Transthoracic echocardiography findings included new tricuspid regurgitation and two mobile echodensities on the right atrial implantable cardioverter defibrillator (ICD) lead. Despite broad antibiotic coverage and extraction of the ICD leads, the patient passed away from septic shock. Discussion/UNASSIGNED:genus were isolated in patients' blood cultures. This evidence supports the endotoxin theory as the leading pathophysiologic explanation for cotton fever and suggests cotton fever as a risk factor for Gram-negative IE. In the inpatient setting it informs proper antibiotic coverage, whereas in the outpatient setting it supports harm reduction interventions in the form of sterile cotton balls.

OBJECTIVE/UNASSIGNED:To characterize factors associated with increased risk of outpatient parenteral antimicrobial therapy (OPAT) complication. DESIGN/UNASSIGNED:Retrospective cohort study. SETTING/UNASSIGNED:Four hospitals within NYU Langone Health (NYULH). PATIENTS/UNASSIGNED:All patients aged ≥18 years with OPAT episodes who were admitted to an acute-care facility at NYULH between January 1, 2017, and December 31, 2020, who had an infectious diseases consultation during admission. RESULTS/UNASSIGNED:< .001). CONCLUSIONS/UNASSIGNED:Discharge to an SARC is strongly associated with increased risks of readmission for OPAT-related complications and CRBSI. Loss to follow-up with the infectious diseases service is strongly associated with increased risk of readmission and CRBSI. CRBSI prevention during SARC admission is a critically needed public health intervention. Further work must be done for patients undergoing OPAT to improve their follow-up retention with the infectious diseases service.

BACKGROUND Herpes simplex virus-2 (HSV-2) affects nearly 1 in 5 adults in the United States. Complications such as viral hepatitis and dissemination are rare in immunocompetent hosts. In this report, we describe a case of viral hepatitis secondary to disseminated HSV-2 in an immunocompetent patient with recurrent fevers and elevated aminotransferases. CASE REPORT A 57-year-old man with a history of type 2 diabetes and hypertension was admitted with a right index finger lesion concerning for an abscess. He underwent successful incision and drainage and was started on ampicillin-sulbactam. On Day 2 of hospitalization, he developed recurrent fevers and elevated aminotransferases and inflammatory markers. An extensive infectious, rheumatologic, and malignancy workup were pursued without immediate findings. Imaging demonstrated cirrhotic morphology of the liver and splenomegaly, but lab markers were intact for liver synthetic function. On Day 7 of hospitalization, fever frequency decreased, and HSV-2 titers resulted, with positive IgM and negative IgG. He subsequently developed erythematous, raised lesions in multiple dermatomes. Nucleic acid amplification testing of biopsied lesions was positive for HSV-2, confirming viral hepatitis secondary to disseminated HSV-2. He was started on intravenous acyclovir and discharged on valacyclovir following improvement in symptoms. CONCLUSIONS We report a case of viral hepatitis secondary to disseminated HSV-2 in an immunocompetent host. Up to 25% of cases occur in immunocompetent hosts and many patients do not develop characteristic skin lesions. Early diagnosis and treatment of viral hepatitis secondary to disseminated HSV remains vital to minimize morbidity and mortality.
