Surgeon preferences are associated with utilization of telehealth in fracture care.

BACKGROUND: The SARS-CoV-2 (COVID-19) pandemic has the potential to evoke lasting changes in the delivery of care, and the utilization of telehealth. We sought associations between surgeon personal factors and greater use of telehealth to treat fractures relative to in-person care. METHODS: Seventy-five fracture surgeons participated in a survey-based experiment. All surgeons were asked about their preferences regarding remote compared to in-person communication. Participants rated the following items on slider scales: their degree of introversion, the importance of a hands-on/physical exam and surgeon preferences regarding telehealth. We identified factors associated with the use of, and comfort with, telehealth. RESULTS: The use of telehealth during the pandemic was associated with comfort evaluating wounds via telehealth. A greater proportion of remote visits was associated with comfort evaluating wounds and confidence teaching exercises via telehealth. There was consensus that telehealth did not alter utilization rates of radiographs or offer of discretionary surgery. The use of absorbable sutures to limit in-person visits was associated with a preference for working from home and greater comfort with evaluating wounds remotely. The use of 2- and 6-week post-operative telehealth visits and plans to use telehealth after the pandemic (52%) were associated with greater comfort in evaluating wounds through telehealth and greater confidence with video instruction of exercises. CONCLUSIONS: The finding that personal factors are associated with utilization of telehealth helps target strategies for increased use of telehealth and other technologies as the pandemic wanes. Given that telehealth adds convenience for people with ambulatory difficulties or in remote areas, such efforts are warranted. LEVEL OF EVIDENCE: Not applicable.

The Impact of Interpretation Biases on Psychological Responses to the COVID-19 Pandemic: a Prospective Study.

BACKGROUND: This study investigates the longitudinal role of interpretation biases in the development and maintenance of health anxiety during the pandemic. Individual differences in behavioural responses to the virus outbreak and decision-making were also examined. METHODS: Two hundred seventy-nine individuals from a pre-pandemic study of interpretation bias and health anxiety completed an online survey during the third wave of the COVID-19 pandemic in Hong Kong. Participants' health anxiety, interpretation biases, and COVID-specific behaviours (i.e. practice of social distancing, adherence to preventive measures, information seeking), and health decision-making were assessed. RESULTS: Pre-pandemic tendencies to interpret ambiguous physical sensations as signals for illness did not predict health anxiety during the pandemic, b = -0.020, SE = 0.024, t = -0.843, p = .400, 99% CI [-0.082, 0.042], but were associated with a preference for risky treatment option for COVID-19, b = 0.026, SE = 0.010, Wald = 2.614, p = .009, OR = 1.026, 99% CI [1.001, 1.054]. Interpretation biases and health anxiety symptoms during the pandemic were associated with each other and were both found to be significant predictors of practice of social distancing, adherence to preventive measures, and information seeking behaviour. CONCLUSIONS: This study adds to the growing evidence of the role of interpretation biases in health anxiety and the way that people respond to the ongoing pandemic.

Content validity and psychometric properties of the inFLUenza Patient-Reported Outcome Plus (FLU-PRO Plus©) instrument in patients with COVID-19.

PURPOSE: A well-defined and reliable patient-reported outcome instrument for COVID-19 is important for assessing symptom severity and supporting research studies. The InFLUenza Patient-Reported Outcome (FLU-PRO) instrument has been expanded to include loss of taste and smell in the FLU-PRO Plus, to comprehensively cover COVID-19 symptoms. Our studies were designed to evaluate and validate the FLU-PRO Plus among patients with COVID-19. METHODS: Two studies were conducted: (1) a qualitative, non-interventional, cross-sectional study of patients with COVID-19 involving hybrid concept elicitation and cognitive debriefing interviews; (2) a psychometric evaluation of the measurement properties of FLU-PRO Plus, using data from COMET-ICE (COVID-19 Monoclonal antibody Efficacy Trial-Intent to Care Early). RESULTS: In the qualitative interviews (n = 30), all 34 items of the FLU-PRO Plus were considered relevant to COVID-19, and participants determined the questionnaire was easily understood, well written, and comprehensive. In the psychometric evaluation (n = 845), the internal consistency reliability of FLU-PRO Plus total score was 0.94, ranging from 0.71 to 0.90 for domain scores. Reproducibility (Day 20-21) was 0.83 for total score, with domain scores of 0.67-0.89. Confirmatory factor analysis with the novel smell/taste domain demonstrated an acceptable fit to the data. CONCLUSION: The content, reliability, validity, and responsiveness of the FLU-PRO Plus in the COVID-19 population were supported. Our results suggest that FLU-PRO Plus is a content- and psychometrically-valid, fit-for-purpose measure which is easily understood by patients. FLU-PRO Plus is a suitable PRO measure for evaluating symptoms of COVID-19 and treatment benefit directly from the patient perspective.

PVP1—The People’s Ventilator Project: A fully open, low-cost, pressure-controlled ventilator research platform compatible with adult and pediatric uses

Mechanical ventilators are safety-critical devices that help patients breathe, commonly found in hospital intensive care units (ICUs)—yet, the high costs and proprietary nature of commercial ventilators inhibit their use as an educational and research platform. We present a fully open ventilator device—The People’s Ventilator: PVP1—with complete hardware and software documentation including detailed build instructions and a DIY cost of $1,700 USD. We validate PVP1 against both key performance criteria specified in the U.S. Food and Drug Administration’s Emergency Use Authorization for Ventilators, and in a pediatric context against a state-of-the-art commercial ventilator. Notably, PVP1 performs well over a wide range of test conditions and performance stability is demonstrated for a minimum of 75,000 breath cycles over three days with an adult mechanical test lung. As an open project, PVP1 can enable future educational, academic, and clinical developments in the ventilator space.

Histological and serological features of acute liver injury after SARS-CoV-2 vaccination

Background & Aims Liver injury with autoimmune features after vaccination against Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2) is increasingly reported. We investigated a large international cohort of patients with acute hepatitis arising after SARS-CoV-2 vaccination, focusing on histological and serological features. Approach & Results Patients without known pre-existing liver diseases and transaminase levels ≥5x the upper limit of normal within 3 months after any anti-SARS-CoV-2 vaccine and available liver biopsy are included. Fifty-nine patients were recruited;35 females;median age 54 years;they were exposed to various combinations of mRNA, vectorial, inactivated and protein-based vaccines. Liver histology showed predominantly lobular hepatitis in 45 (76%) cases, predominantly portal hepatitis in 10 (17%), and other patterns in four (7%);seven had fibrosis Ishak stage ≥3, associated with more severe interface hepatitis. Autoimmune serology, centrally tested in 31 cases, showed anti-antinuclear antibody in 23 (74%), anti-smooth muscle antibody in 19 (61%), anti-gastric parietal cells in 8 (26%), anti-liver kidney microsomal in 4 (13%), anti-mitochondrial antibody in 4 (13%). Ninety-one percent were treated with steroids, ± azathioprine. Serum transaminase levels improved in all cases, and were normal in 24/58 (41%) after three months, and in 30/46 (65%) after six months. One patient required liver transplantation. Re-exposure to SARS-CoV-2 vaccines of 15 patients resulted in three relapses. Conclusion Acute liver injury arising after SARS-CoV-2 vaccination is frequently associated with lobular hepatitis and positive autoantibodies. Whether there is a causal relationship between liver damage and SARS-CoV-2 vaccines remains to be established. A close follow-up is warranted to assess the long-term outcome of this condition. Lay summary Cases of liver injury after vaccination against Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2) have been published. We investigated a large international cohort of patients with acute hepatitis after SARS-CoV-2 vaccination, focusing on liver biopsy findings and autoantibodies: liver biopsy frequently shows inflammation of the lobule, which is typical of recent injury, and autoantibodies are frequently positive. Whether there is a causal relationship between liver damage and SARS-CoV-2 vaccines remains to be established. Close follow-up is warranted to assess the long-term outcome of this condition.

Surgeon Personal Factors Associated with Care Strategies in Musculoskeletal Telehealth.

Background: Most surgeons used, or are currently using telehealth during the SARS-CoV-2 (COVID-19) pandemic. We studied surgeon personal factors associated with relative use of telehealth during the worldwide height of the pandemic. Questions/Purposes: (1) Are there any personal factors/characteristics associated with use and utilization of telehealth? (2) What are surgeon's perspectives/ opinions with regard to use of telehealth for five common upper extremity conditions in terms of future prospects and viability? Methods: Hand and upper extremity surgeons in the Science of Variation Group (SOVG) were invited to participate in a web-based survey. The first part of the survey focused on surgeon characteristics and work preferences. The second part focused on care strategies during the pandemic and utilization of telehealth. The final part of the survey addressed the care of five common upper extremity conditions during the pandemic. Results: Ninety percent of surgeons used telehealth during the first few months of the pandemic, but only 20% of visits were virtual. A greater percentage of telehealth visits compared to office visits was independently associated with a policy of only seeing people with emergencies in person (RC: 0.64; CI 95%: 0.21 to 1.1; P<0.01). Surgeons found it difficult to reproduce most parts of the physical examination on video, but relatively easy to make a diagnosis, with both ratings associated with less belief that the physical exam is essential. Comfort in offering surgery by video visit was associated with having young children, preference for remote meetings, and less belief that the physical exam is essential. Conclusion: Utilization of, and comfort with, telehealth is related to personal factors and preferences, acceptance of a more limited physical examination in particular. Utilization of early adopters and training to increase comfort with the probabilistic aspects of medicine could facilitate incorporation of telehealth into standard practice.

The effects of efficacy framing in news information and health anxiety on coronavirus-disease-2019-related cognitive outcomes and interpretation bias.

Within the coronavirus-disease-2019 (COVID-19) pandemic, disease-related information is omnipresent in the media, whereas information about how to manage the pandemic is less often covered. Under the context where threat is present, this study investigated whether and how the strength of efficacy framing (i.e., the perspective adopted by a communicating text that emphasizes one's possibilities to cope with an external threat) of COVID-19-related news, as well as its interaction with trait health anxiety under the COVID-19 context, related to people's COVID-19-related cognitive outcomes. One hundred and ninety-three participants reported demographics, trait health anxiety, and COVID-19-related behaviors (e.g., precautionary measures, information-seeking behaviors). They then either read high-efficacy (n = 112; e.g., cure rate) or low-efficacy (n = 81; e.g., mortality rate) information about COVID-19. Afterward, their tendency to interpret illness- and COVID-19-related information more negatively, and other COVID-19-related cognitions (e.g., risk perception, behavioral change intentions) were assessed. High-efficacy framing resulted in lower-risk perception and marginally weaker COVID-19-related interpretation bias, compared with low-efficacy framing. There was some evidence of an interaction with health anxiety such that high-efficacy framing, compared with low-efficacy framing, was associated with greater intention to adopt protective behaviors, particularly for individuals with higher levels of health anxiety. Media framing of COVID-19 information affects how people respond to the pandemic; a high-efficacy communication style might more effectively encourage healthy behaviors than a low-efficacy narrative, particularly for people who are already anxious about their health.

Deep learning approach based on superpixel segmentation assisted labeling for automatic pressure ulcer diagnosis.

A pressure ulcer is an injury of the skin and underlying tissues adjacent to a bony eminence. Patients who suffer from this disease may have difficulty accessing medical care. Recently, the COVID-19 pandemic has exacerbated this situation. Automatic diagnosis based on machine learning (ML) brings promising solutions. Traditional ML requires complicated preprocessing steps for feature extraction. Its clinical applications are thus limited to particular datasets. Deep learning (DL), which extracts features from convolution layers, can embrace larger datasets that might be deliberately excluded in traditional algorithms. However, DL requires large sets of domain specific labeled data for training. Labeling various tissues of pressure ulcers is a challenge even for experienced plastic surgeons. We propose a superpixel-assisted, region-based method of labeling images for tissue classification. The boundary-based method is applied to create a dataset for wound and re-epithelialization (re-ep) segmentation. Five popular DL models (U-Net, DeeplabV3, PsPNet, FPN, and Mask R-CNN) with encoder (ResNet-101) were trained on the two datasets. A total of 2836 images of pressure ulcers were labeled for tissue classification, while 2893 images were labeled for wound and re-ep segmentation. All five models had satisfactory results. DeeplabV3 had the best performance on both tasks with a precision of 0.9915, recall of 0.9915 and accuracy of 0.9957 on the tissue classification; and a precision of 0.9888, recall of 0.9887 and accuracy of 0.9925 on the wound and re-ep segmentation task. Combining segmentation results with clinical data, our algorithm can detect the signs of wound healing, monitor the progress of healing, estimate the wound size, and suggest the need for surgical debridement.

Two Fifth-Generation Fighter Pilots Discovered with Latent Autoimmune Diabetes.

BACKGROUND: Fighter pilots undergo extensive medical screening but may still miss rare diseases like latent autoimmune diabetes in adults (LADA). LADA patients have circulating autoantibodies directed against pancreatic beta cell antigens and present with frank diabetes late in life which may elude conventional military flight screening.CASE REPORT: Two fifth-generation fighter pilots, a 38-yr-old man (patient 1) and a 27-yr-old man (patient 2), with no significant past medical histories developed symptoms of fatigue, weight loss, episodic polyuria, and arthralgia. Patient 1's symptoms were initially thought to have been caused by COVID-19, but he subsequently tested negative for viral infection. Lab work instead showed elevated TSH, HgbA1C 11.4%, positive GAD-65, anti-TPO, and anti-islet cell antibodies. Patient 2 developed symptoms following a military deployment and a 72-h diarrheal illness. Due to flight status, patient 2 did not seek expert medical attention for several months, but lab work found HgbA1C of 10.4%, positive GAD-66, and ZnT8 antibodies. Both patients were started on insulin therapy. Patient 1 was also started on levothyroxine for hypothyroidism and retired from flying duties. Patient 2 eventually transitioned to metformin without insulin and returned to flying duties with an aeromedical waiver.DISCUSSION: Our patients maintained peak physical fitness throughout their selection and aviation careers, which likely delayed their clinical presentation. Current USAF flight rules prohibit insulin use with flying fighter aircraft. Early antibody screening during pilot selection may be a cost-effective means of diagnosis as traditional screening techniques are unlikely to detect LADA.Zhang JX, Berry J, Kim NM, Gray JJ, Fotheringham S, Sauerwein TJ.

A Systematic Review and Meta-Analysis of Inpatient Mortality Associated With Nosocomial and Community COVID-19 Exposes the Vulnerability of Immunosuppressed Adults.

Background: Little is known about the mortality of hospital-acquired (nosocomial) COVID-19 infection globally. We investigated the risk of mortality and critical care admission in hospitalised adults with nosocomial COVID-19, relative to adults requiring hospitalisation due to community-acquired infection. Methods: We systematically reviewed the peer-reviewed and pre-print literature from 1/1/2020 to 9/2/2021 without language restriction for studies reporting outcomes of nosocomial and community-acquired COVID-19. We performed a random effects meta-analysis (MA) to estimate the 1) relative risk of death and 2) critical care admission, stratifying studies by patient cohort characteristics and nosocomial case definition. Results: 21 studies were included in the primary MA, describing 8,251 admissions across 8 countries during the first wave, comprising 1513 probable or definite nosocomial COVID-19, and 6738 community-acquired cases. Across all studies, the risk of mortality was 1.3 times greater in patients with nosocomial infection, compared to community-acquired (95% CI: 1.005 to 1.683). Rates of critical care admission were similar between groups (Relative Risk, RR=0.74, 95% CI: 0.50 to 1.08). Immunosuppressed patients diagnosed with nosocomial COVID-19 were twice as likely to die in hospital as those admitted with community-acquired infection (RR=2.14, 95% CI: 1.76 to 2.61). Conclusions: Adults who acquire SARS-CoV-2 whilst already hospitalised are at greater risk of mortality compared to patients admitted following community-acquired infection; this finding is largely driven by a substantially increased risk of death in individuals with malignancy or who had undergone transplantation. These findings inform public health and infection control policy and argue for individualised clinical interventions to combat the threat of nosocomial COVID-19, particularly for immunosuppressed groups.

Systematic review of postoperative therapy for resected squamous cell carcinoma of the head and neck: Executive summary of the American Radium Society appropriate use criteria.

BACKGROUND: The aims of this systematic review are to (a) evaluate the current literature on the impact of postoperative therapy for resected squamous cell carcinoma of the head and neck (SCCHN) on oncologic and non-oncologic outcomes and (b) identify the optimal evidence-based postoperative therapy recommendations for commonly encountered clinical scenarios. METHODS: An analysis of the medical literature from peer-reviewed journals was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. Prospective studies and methodology-based systematic reviews and meta-analyses of postoperative therapy for SCCHN were identified by searching Medline (OVID) and EMBASE (Elsevier) using controlled vocabulary terms (ie, National Library of Medicine Medical Subject Headings [MeSH], EMTREE). Study screening and selection was performed with Covidence software and full-text review. The RAND/UCLA appropriateness method was used by the expert panel to rate the appropriate use of postoperative therapy, and the modified Delphi method was used to come to consensus. RESULTS: A total of 5660 studies were identified and screened using the title and abstract, leading to 201 studies assessed for relevance using full-text review. After limitation to the eligibility criteria, 101 studies from 1977 to 2020 were identified, including 77 with oncologic endpoints and 24 with function and quality of life endpoints. All studies reported staging prior to the implementation of American Joint Committee on Cancer (AJCC-8). CONCLUSIONS: Prospective clinical studies and systematic reviews identified through the PRISMA systematic review provided good evidence for consensus statements regarding the appropriate use of postoperative therapy for resected SCCHN. Further research is needed in domains where consensus by the expert panel could not be achieved for the appropriateness of specific postoperative therapeutic interventions.

Exploring sports nutritionists' and players' perspectives of nutrition practice within English professional football during the COVID-19 pandemic.

The outbreak of the COVID-19 pandemic, and the subsequent suspension of all football-related activity, caused significant disruption to the daily habits of professional football players and support staff. Even when the most severe restrictions were lifted, strict control measures remained in place which likely continued to impact upon nutrition support and intake of players. Thus, this study aimed to understand how restrictions impacted upon nutrition support within professional football, as well as identify how these experiences could inform future practice. Interviews were conducted with twelve sports nutritionists and twelve male professional football players to explore their perspectives of nutrition provision during the COVID-19 pandemic. Thematic analysis indicated three common outcomes: (a) Sub-optimal Nutrition Provision; (b) Reduction in Time with or Access to Players, and; (c) Adaption of Nutrition Practice and/or Dietary Habits. In sum, football clubs should consider the immediate and short-term impact of COVID-19 restrictive measures as players' transition back to normality. Specifically, clubs should provide sports nutritionists with greater capacity to control the nutrition provision, including portion size and food quality. Looking ahead, sports nutritionists are encouraged to reflect upon the novel opportunities that have emerged and consider how these may enhance long-term practice.

Pneumocystis pneumonia, a COVID-19 mimic, reminds us of the importance of HIV testing in COVID-19.

While clinical environments are highly focused on COVID-19, reports of missed or delayed treatment for conditions that imitate COVID-19, such as pneumonia caused by the fungus Pneumocystis jirovecii, are emerging. Given the uncertain spectrum of COVID-19 presentations and variable sensitivity of laboratory tests for SARS-CoV-2, there is a risk that, without a high index of suspicion, alternative aetiologies may be overlooked while pursuing a diagnosis of COVID-19. The British HIV Association has been calling for the inclusion of HIV testing in all patients admitted to hospital with suspected COVID-19. In this article we reflect on the importance of including HIV testing to prevent avoidable morbidity and mortality in our patients.
