Effect of various decontamination procedures on disposable N95 mask integrity and SARS-CoV-2 infectivity.

J Clin Transl Sci 2020 Jun 11;5(1):e10. Epub 2020 Jun 11.

Providence Portland Medical Center, Department of Medicine, Portland, Oregon, USA.

Introduction: The COVID-19 pandemic has created a high demand on personal protective equipment, including disposable N95 masks. Given the need for mask reuse, we tested the feasibility of vaporized hydrogen peroxide (VHP), ultraviolet light (UV), and ethanol decontamination strategies on N95 mask integrity and the ability to remove the infectious potential of SARS-CoV-2.

Methods: Disposable N95 masks, including medical grade (1860, 1870+) and industrial grade (8511) masks, were treated by VHP, UV, and ethanol decontamination. Mask degradation was tested using a quantitative respirator fit testing. Pooled clinical samples of SARS-CoV-2 were applied to mask samples, treated, and then either sent immediately for real-time reverse transcriptase-polymerase chain reaction (RT-PCR) or incubated with Vero E6 cells to assess for virucidal effect.

Results: Both ethanol and UV decontamination showed functional degradation to different degrees while VHP treatment showed no significant change after two treatments. We also report a single SARS-CoV-2 virucidal experiment using Vero E6 cell infection in which only ethanol treatment eliminated detectable SARS-CoV-2 RNA.

Conclusions: We hope our data will guide further research for evidenced-based decisions for disposable N95 mask reuse and help protect caregivers from SARS-CoV-2 and other pathogens.

Early Outcomes in an Emerging Facial Nerve Center: The Oregon Health and Science University (OHSU) Experience.

Ann Otol Rhinol Laryngol 2021 May 11;130(5):459-466. Epub 2020 Sep 11.

Department of Otolaryngology-Head & Neck Surgery, Oregon Health & Science University, Portland, OR, USA.

Objectives: Nerve transfer (NT) and free gracilis muscle transfer (FGMT) are procedures for reanimation of the paralyzed face. Assessing the surgical outcomes of these procedures is imperative when evaluating the effectiveness of these interventions, especially when establishing a new center focused on the treatment of patients with facial paralysis. We desired to discuss the factors to consider when implementing a facial nerve center and the means by which the specialist can assess and analyze outcomes.

Methods: Patients with facial palsy secondary to multiple etiologies, including cerebellopontine angle tumors, head and neck carcinoma, and trauma, who underwent NT or FGMT between 2014 and 2019 were included. Primary outcomes were facial symmetry and smile excursion, calculated using FACE-gram and Emotrics software. Subjective quality of life outcomes, including the Facial Clinimetric Evaluation (FaCE) Scale and Synkinesis Assessment Questionnaire (SAQ), were also assessed.

Results: 14/22 NT and 6/6 FGMT patients met inclusion criteria having both pre-and postoperative photo documentation. NT increased oral commissure excursion from 0.4 mm (SD 5.3) to 2.9 mm (SD 6.8) ( = 0.05), and improved symmetry of excursion ( < 0.001) and angle ( < 0.001). FGMT increased oral commissure excursion from -1.4 mm (SD 3.9) to 2.1 mm (SD 3.7), ( = 0.02), and improved symmetry of excursion ( < 0.001). FaCE scores improved in NT patients postoperatively ( < 0.001).

Conclusions: Measuring outcomes, critical analyses, and a multidisciplinary approach are necessary components when building a facial nerve center. At our emerging facial nerve center, we found NT and FGMT procedures improved smile excursion and symmetry, and improved QOL following NT in patients with facial palsy secondary to multiple etiologies.

Degree of Self-Reported Facial Impairment Correlates with Social Impairment in Individuals with Facial Paralysis and Synkinesis.

Facial Plast Surg Aesthet Med 2020 May 14. Epub 2020 May 14.

Facial paralysis leads to both aesthetic and functional deficits placing patients at risk for sociopsychological sequelae and social impairment. To examine the effect of facial paralysis and synkinesis on social impairment and quality of life (QOL). This is a cross-sectional study at a tertiary care medical center. Adults with a history of facial palsy were broadly categorized by self-reported degree of facial paralysis and synkinesis. Clinical demographic information, self-reported degrees of facial paralysis and synkinesis, and facial palsy-specific QOL as measured by the Facial Clinimetric Evaluation (FaCE) Scale and the Synkinesis Assessment Questionnaire (SAQ) were collected. FaCE and SAQ scales were evaluated as predictors of social impairment outcomes, as measured by the Brief Fear of Negative Evaluation-II (BFNE-II), the Social Anxiety Questionnaire (SAQ-A30), and Social Avoidance and Distress (SAD) scales, in addition to health utility scores from the Short-Form 6D (SF-6D). : Fifty-six participants with facial palsy were included (30% male; average age: 56.4 [standard deviation (SD): 15] years). Sixty-three percent of participants reported history of Bell's palsy; 37% reported other etiologies. Forty-seven percent of participants reported moderate or severe facial impairment and 46% of participants reported involuntary facial movement. Participants with moderate or severe facial impairment exhibited increased BFNE-II ( = 0.03), SAQ-A30 ( = 0.04), and SAD ( < 0.01) scores and lower health valuation on SF-6D ( = 0.04). FaCE scores moderately correlated with lower health valuation ( = 0.39,  < 0.01), and moderately and inversely correlated with SAD ( = -0.33,  = 0.01) and BFNE-II ( = -0.35,  < 0.01) scores. Furthermore, worsening FaCE scores predicted worsening SAQ ( < 0.01), SAD ( = 0.01), BFNE-II ( < 0.01), and SF-6D ( < 0.01) scores. Worse degrees of synkinesis correlated with higher BFNE-II scores ( = 0.38,  < 0.01) and worsening SAQ scores predicted worsening FaCE ( < 0.01) and BFNE-II ( < 0.01) scores. Females demonstrated significantly worse BFNE-II scores ( = 0.04) when compared with men, and female gender significantly predicted worse FaCE scores ( < 0.01). Seventy-one percent of women with self-reported moderate or severe facial impairment met criteria for social anxiety, as did 67% of women with self-reported moderate or severe synkinesis. : Individuals with self-reported moderate or severe facial impairment exhibit a higher degree of social impairment and poorer health valuation than those with no or mild facial impairment. Facial palsy-specific QOL moderately and inversely correlated with social impairment and moderately correlated with health valuation. Our results indicate that FaCE scores may be used as a predictor of SAD, BFNE-II, and SF-6D scores and that facial palsy QOL and its relationship with social impairment should be considered when treating patients with a history of facial palsy.

Software Prototyping: A Case Report of Refining User Requirements for a Health Information Exchange Dashboard.

Appl Clin Inform 2016 13;7(1):22-32. Epub 2016 Jan 13.

University of Utah , Salt Lake City, UT, USA.

Background: Health information exchange (HIE) between Poison Control Centers (PCCs) and Emergency Departments (EDs) could improve care of poisoned patients. However, PCC information systems are not designed to facilitate HIE with EDs; therefore, we are developing specialized software to support HIE within the normal workflow of the PCC using user-centered design and rapid prototyping.

Objective: To describe the design of an HIE dashboard and the refinement of user requirements through rapid prototyping.

Methods: Using previously elicited user requirements, we designed low-fidelity sketches of designs on paper with iterative refinement. Next, we designed an interactive high-fidelity prototype and conducted scenario-based usability tests with end users. Users were asked to think aloud while accomplishing tasks related to a case vignette. After testing, the users provided feedback and evaluated the prototype using the System Usability Scale (SUS).

Results: Survey results from three users provided useful feedback that was then incorporated into the design. After achieving a stable design, we used the prototype itself as the specification for development of the actual software. Benefits of prototyping included having 1) subject-matter experts heavily involved with the design; 2) flexibility to make rapid changes, 3) the ability to minimize software development efforts early in the design stage; 4) rapid finalization of requirements; 5) early visualization of designs; 6) and a powerful vehicle for communication of the design to the programmers. Challenges included 1) time and effort to develop the prototypes and case scenarios; 2) no simulation of system performance; 3) not having all proposed functionality available in the final product; and 4) missing needed data elements in the PCC information system.
