Increased rates of secondary bacterial infections, including Enterococcus bacteremia, in patients hospitalized with coronavirus disease 2019 (COVID-19).

OBJECTIVE: We compared the rates of hospital-onset secondary bacterial infections in patients with coronavirus disease 2019 (COVID-19) with rates in patients with influenza and controls, and we investigated reports of increased incidence of Enterococcus infections in patients with COVID-19. DESIGN: Retrospective cohort study. SETTING: An academic quaternary-care hospital in San Francisco, California. PATIENTS: Patients admitted between October 1, 2019, and October 1, 2020, with a positive SARS-CoV-2 PCR (N = 314) or influenza PCR (N = 82) within 2 weeks of admission were compared with inpatients without positive SARS-CoV-2 or influenza tests during the study period (N = 14,332). METHODS: National Healthcare Safety Network definitions were used to identify infection-related ventilator-associated complications (IVACs), probable ventilator-associated pneumonia (PVAP), bloodstream infections (BSIs), and catheter-associated urinary tract infections (CAUTIs). A multiple logistic regression model was used to control for likely confounders. RESULTS: COVID-19 patients had significantly higher rates of IVAC and PVAP compared to controls, with adjusted odds ratios of 4.7 (95% confidence interval [CI], 1.7-13.9) and 10.4 (95 % CI, 2.1-52.1), respectively. COVID-19 patients had higher incidence of BSI due to Enterococcus but not BSI generally, and whole-genome sequencing of Enterococcus isolates demonstrated that nosocomial transmission did not explain the increased rate. Subanalyses of patients admitted to the intensive care unit and patients who required mechanical ventilation revealed similar findings. CONCLUSIONS: COVID-19 is associated with an increased risk of IVAC, PVAP, and Enterococcus BSI compared with hospitalized controls, which is not fully explained by factors such as immunosuppressive treatments and duration of mechanical ventilation. The mechanism underlying increased rates of Enterococcus BSI in COVID-19 patients requires further investigation.

Fly rounds: Validation and pilot of a novel epidemiologic tool to guide infection control response to an infestation of Sarcophagidae flies in a community hospital's perioperative department.

During an outbreak of Sarcophagidae, or flesh flies, in a community hospital's perioperative department, the infection prevention and control (IPC) department developed, validated, and piloted a novel epidemiologic tool to track hourly fly prevalence by room. Interrater reliability of the tool was measured as 0.88 and hourly point prevalence counts were superimposed on floor plans to create heat maps. Such surveillance tools allowed more timely decision making in conjunction with the operations of the hospital incident command system.

Novel nonablative radio-frequency rejuvenation device applied to the neck and jowls: clinical evaluation and 3-dimensional image analysis.

OBJECTIVE: To use 3D photography to evaluate the clinical efficacy of a novel radiofrequency delivery device used to improve the appearance of rhytids and laxity of the face and neck. STUDY DESIGN: Forty-nine subjects received a total of two radio-frequency treatments to the face and neck one-month apart. The novel radio-frequency delivery device was used to heat the dermis between 41-43°C for five heat cycles. Primary outcome measures were clinical efficacy quantified by the Global Assessment Improvement Scale (GAIS) and a patient survey that assessed treatment satisfaction. RESULTS: Assessments of 3D photographs revealed an overall improvement in 74% of study subjects. 85% of patients noted an overall improvement in the appearance of their skin. 81% of patients rated their post-treatment skin laxity as improved, 85% rated their skin smoothness as improved and 62% rated their skin brightness as improved. CONCLUSION: Subjects in this study demonstrated an overall improvement in face and neck appearance with regard to skin tightening, wrinkles, and skin texture suggested by overall patient satisfaction (85%) and physician-rated GAIS improvement (74%). This study suggests that radiofrequency applied with a continuous thermal treatment device is a safe and efficacious way to improve the overall appearance of aging facial skin.

Improved texture and appearance of human facial skin after daily topical application of barley produced, synthetic, human-like epidermal growth factor (EGF) serum.

A three month, open-label, single center study was conducted to determine whether a uniquely derived serum containing barley bioengineered, human-like epidermal growth factor protein could improve visible signs of photodamage and aging in facial skin. Twenty-nine females, aged 39 to 75 years, with mild to severe, fine and course rhytids, photodamage, and pigmentation were enrolled. Subjects then applied the treatment serum per the prescribed protocol twice-daily for 3 months, in addition to the use of a basic sunscreen and facial cleanser. In-person clinical evaluations and subject self-assessment questionnaires were administered at each follow up visit. In addition, clinical photography was completed at baseline, and each subsequent visit. Clinical evaluations showed statistically significant improvement in the appearance of fine lines and rhytids, skin texture, pore size, and various dyschromatic conditions apparent within the first month of use, and continuing improvement trends for the duration of the study. The treatment serum was well tolerated with minimal treatment-related complications reported throughout. Efficacy of this novel serum and treatment protocol resulted in meaningful improvements in photodamage and visible signs of aging.
