Higher quality research on the benefits and harms of CP in the control of endemic MRSA and VRE is needed. Until more definitive data are available, the use of CP for endemic MRSA or VRE in acute care hospitals should be guided by local needs and resources.

Healthcare personnel (HCP) attire is an aspect of the medical profession steeped in culture and tradition. The role of attire in cross-transmission remains poorly established and until more definitive information exists, priority should be placed on evidence-based measures to prevent hospital acquired infections (HAI). This paper aims to provide a general guidance to the medical community regarding HCP attire outside the operating room. In addition to the initial guidance statement, the manuscript has three major components: 1. A review and interpretation of the medical literature regarding a) perceptions of HCP attire (from both HCP and patients) and b) evidence for contamination of attire and its potential contribution to cross-transmission; 2. A review of hospital policies related to HCP attire, as submitted by members of the SHEA Guidelines Committee; 3. A survey of SHEA and SHEA Research Network members, which assessed both institutional HCP attire policies and perceptions of HCP attire in the cross-transmission of pathogens. Recommendations for HCP attire should attempt to balance professional appearance, comfort, and practicality with the potential role of apparel in the cross-transmission of pathogens. Although the optimal choice of HCP attire for inpatient care remains undefined, we provide recommendations on the use of white coats, neck ties, footwear, the bare-below-the-elbows strategy, and laundering. Institutions considering these optional measures should introduce them with a well-organized communication and education effort directed at both HCP and patients. Appropriately designed studies are needed to better define the relationship between HCP attire and HAIs.

FQ exposure from widespread prescribing is a modifiable risk factor for FQ resistance in P. aeruginosa. FQ empirical therapy for Pseudomonas infections may be associated with significant delays in administering effective therapy resulting in adverse outcomes.

Introduction: More than 93,000 cases of coronavirus disease have been reported worldwide. We describe the epidemiology, clinical course, and virologic characteristics of the first 12 U.S. patients with COVID-19. Methods:We collected demographic, exposure, and clinical information from 12 patients confirmed by CDC during January 20-February 5, 2020 to have COVID-19. Respiratory, stool, serum, and urine specimens were submitted for SARS-CoV-2 rRT-PCR testing, virus culture, and whole genome sequencing. Results:Among the 12 patients, median age was 53 years (range: 21-68); 8 were male, 10 had traveled to China, and two were contacts of patients in this series. Commonly reported signs and symptoms at illness onset were fever (n=7) and cough (n=8). Seven patients were hospitalized with radiographic evidence of pneumonia and demonstrated clinical or laboratory signs of worsening during the second week of illness. Three were treated with the investigational antiviral remdesivir. All patients had SARS-CoV-2 RNA detected in respiratory specimens, typically for 2-3 weeks after illness onset, with lowest rRT-PCR Ct values often detected in the first week. SARS-CoV-2 RNA was detected after reported symptom resolution in seven patients. SARS-CoV-2 was cultured from respiratory specimens, and SARS-CoV-2 RNA was detected in stool from 7/10 patients. Conclusions:In 12 patients with mild to moderately severe illness, SARS-CoV-2 RNA and viable virus were detected early, and prolonged RNA detection suggests the window for diagnosis is long. Hospitalized patients showed signs of worsening in the second week after illness onset.for use under a CC0 license.

Patients with inflammatory bowel disease (IBD), namely ulcerative colitis (UC) and Crohn's disease (CD), have worse outcomes with Clostridium difficile infection (CDI), including increased readmissions, colectomy, and death. Oral vancomycin is recommended for the treatment of severe CDI, while metronidazole is the standard of care for nonsevere infection. We aimed to assess treatment outcomes of CDI in IBD. We conducted a retrospective observational study of inpatients with CDI and IBD from January 2006 through December 2010. CDI severity was assessed using published criteria. Outcomes included readmission for CDI within 30 days and 12 weeks, length of stay, colectomy, and death. A total of 114 patients met inclusion criteria (UC, 62; CD, 52). Thirty-day readmissions were more common among UC than CD patients (24.2% versus 9.6%; P ‫؍‬ 0.04). Same-admission colectomy occurred in 27.4% of UC patients and 0% of CD patients (P < 0.01). Severe CDI was more common among UC than CD patients (32.2% versus 19.4%; P ‫؍‬ 0.12) but not statistically significant. Two patients died from CDI-associated complications C lostridium difficile causes roughly 20% of antibiotic-associated diarrhea and is responsible for significant morbidity. Its incidence has more than doubled over the past decade (1). Historically, C. difficile infection (CDI) has been associated with such risk factors as antibiotic use, immune suppression and dysfunction, prolonged hospital stays, and advanced age (1-3).Inflammatory bowel disease (IBD) is generally classified as Crohn's disease (CD) or ulcerative colitis (UC), which manifest with intestinal symptoms, including diarrhea and abdominal pain. Patients with IBD are particularly susceptible to the effects of enterocolitic infections, due to underlying alterations in intestinal immunity coupled with often chronic exposure to immunosuppressive therapies. Recent studies have shown that patients with IBD have an increased incidence of developing CDI, with a 2-to 3-fold increase in patients with Crohn's disease and a 4-to 7-fold increase in patients with UC (4-7). Furthermore, patients with underlying IBD who develop CDI experience longer hospital stays and higher rates of colectomy and death than subjects without IBD (5, 8, 9). Consequently, CDI is estimated to have quadrupled the cost of hospitalizations to greater than $1 billion per year relative to matched hospitalizations (1, 10). Several agents have been evaluated for the treatment of CDI, including metronidazole and vancomycin (11).A randomized, controlled trial by Zar et al. demonstrated that vancomycin for the treatment of CDI was associated with improved outcomes in patients meeting criteria for severe CDI, but it conferred no significant advantage over metronidazole for nonsevere disease (12). Notably, patients with IBD were excluded from this trial, and there are no prospective trials comparing antibiotic regimens among patients with CDI and underlying IBD. Largely on the basis of the study by Zar and colleagues, current treatment guidelines rec...
