Healthcare Disruptions and Use of Telehealth Services Among People With Multiple Sclerosis During the COVID-19 Pandemic.

OBJECTIVE: The current study examined health care disruptions and use of telehealth services among people with multiple sclerosis (pwMS) during the COVID-19 pandemic. DESIGN: Cross-sectional survey. SETTING: General community. PARTICIPANTS: Participants (N=163) included 70 pwMS and 93 healthy controls (HCs). The majority of respondents were from the United States (88%). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Rates of health care disruptions (eg, missing/canceling appointments, experiencing delays) and telehealth use for MS and non-MS medical care and mental health care. RESULTS: In this U.S. majority, predominantly White, and high socioeconomic status sample, 38% to 50% of pwMS reported experiencing disruptions in their MS and non-MS medical care and 20% to 33% reported disruptions in their mental health care; this was significantly lower than the rates observed among HCs. Compared with HCs, pwMS were more likely to use telehealth than in-person services, especially for mental health care. The majority of pwMS and HCs reported being satisfied with telehealth services. Individuals with higher degrees of functional limitation experienced more health care disruptions and were more likely to use telehealth services than individuals with lower degrees of functional limitation. CONCLUSIONS: Despite high health care disruption rates, pwMS frequently used and were highly satisfied with telehealth services during the COVID-19 pandemic. Due to physical limitations commonly observed in the MS population that may preclude travel, telehealth services should be continued even after resolution of the pandemic to expand access and reduce health care disparities.

Melbourne colorectal collaboration: a multicentre review of the impact of COVID-19 on colorectal cancer in Melbourne, Australia.

BACKGROUND: As coronavirus (COVID-19) cases continue to rise, healthcare workers have been working overtime to ensure that all patients receive care in a timely manner. Our study aims to identify the impact and outcomes of COVID-19 on colorectal cancers presentations across the five major colorectal units in Melbourne, Australia. METHODS: This is a retrospective study from a prospectively collected database from the binational colorectal cancer audit (BCCA) registry, as well as inpatient records. All patients with colorectal cancer between Pre-COVID-19 period (1 July 2018-2030 June 2019) and COVID-19 period (1 July 2020-2030 June 2021) were compared. Benign pathology and other cancer types were excluded. RESULTS: A total of 1609 patients were included in the study (700 Pre-COVID-19 period, 906 COVID-19 period). During COVID-19 period, there was a higher proportion of emergency surgery (28.1% vs. 19.8%; P < 0.001), a higher nodal (P = 0.024) and metastatic stage (P = 0.018) at presentation, but no increase in the rate of return to operating theatres (P = 0.240), inpatient death (P = 0.019) or 30-day readmission (P = 0.000). There was also no difference in the post-operative surgical complications (P = 0.118). Utility of neoadjuvant therapy did not increase during the pandemic (P = 0.613). CONCLUSION: The heightened measures in the healthcare system ensured CRC patients still received their surgery in a timely fashion. With the current rise in the new strain of COVID-19 (Omicron), we have to continue to come up with new strategies to provide timely access to CRC care.

The impact of the COVID-19 pandemic on engagement in activities of daily living in persons with acquired brain injury.

PRIMARY OBJECTIVES: This study examined (a) the impact of coronavirus disease-2019 (COVID-19) pandemic on engagement in activity participation in persons with acquired brain injury (ABI); and (b) whether changes in activity participation during the pandemic were associated participants' health-related quality of life (HRQoL). RESEARCH DESIGN: Exploratory online survey study. METHODS: Eighty-seven respondents with ABI and 98 healthy adults (HA) participated in this study. Engagement in activity participation during COVID-19 was calculated as a percentage of the activities participants performed before the pandemic. MAIN RESULTS: Participants with ABI modified their activities less than HA in order to maintain level of engagement in activity participation. They stopped performing more activities during the pandemic compared to HA and compared to their pre-pandemic engagement. Both groups continued to do similar percentage of activities without modifications compared to before the pandemic. Better HRQoL in both groups was predicted by a larger percentage of activities continued and fewer activities stopped. CONCLUSION: Results emphasize the importance of addressing activity participation changes during situations where there are disruptions of the individual's habits and routines in order to minimize negative consequences of such changes.

Aquatic exercise for persons with MS: Patient-reported preferences, obstacles and recommendations.

BACKGROUND: Many persons with multiple sclerosis (MS) have difficulties engaging in traditional land-based physical activity due to heat sensitivity and physical disability. Aquatic exercise may be a suitable alternative for these individuals, preventing overheating and enabling a range of movements that were otherwise difficult on land. The objective of the current study was to understand why some persons with MS prefer aquatic exercise while others prefer non-aquatic exercise, which will inform recommendations. METHODS: A total of 179 persons with MS completed a brief online survey (∼10 min) about their exercise routines between October 2020 and April 2021. RESULTS: Fifty-sex percent of respondents reported that they only engaged in non-aquatic exercise (i.e., land-based activities such as jogging), followed by 36% of respondents who reported that they engaged in both aquatic and non-aquatic exercise, and 7% of respondents who participated in aquatic exercise only. The most frequently reported barriers for aquatic exercise were lack of access to pools and its associated expense. Among individuals who had tried aquatic exercise, aquatic exercise was preferred over non-aquatic exercise, and 100% reported that they would recommend aquatic exercise to other persons with MS. Finally, the majority of respondents reported exercising less during the coronavirus disease 2019 (COVID-19) pandemic. CONCLUSION: Aquatic exercise is well liked among persons with MS who have tried it; however, it may not be feasible for economically disadvantaged persons with MS. Local charities and health organizations may consider financially sponsoring aquatic exercise programs to encourage participation in physical activity for the MS population. Due to the negative impact of the pandemic on exercise routines, MS clinicians should encourage their patients to resume their exercise routines once the pandemic subsides.

Immediate smoking cessation support versus usual care in smokers attending a targeted lung health check: the QuLIT trial.

OBJECTIVES: Lung cancer screening programmes offer an opportunity to address tobacco dependence in current smokers. The effectiveness of different approaches to smoking cessation in this context has not yet been established. We investigated if immediate smoking cessation support, including pharmacotherapy, offered as part of a lung cancer screening programme, increases quit rates compared to usual care (Very Brief Advice to quit and signposting to smoking cessation services). MATERIALS AND METHODS: We conducted a single-blind randomised controlled trial of current smokers aged 55-75 years attending a Targeted Lung Health Check. On randomly allocated days smokers received either (1) immediate support from a trained smoking cessation counsellor with appropriate pharmacotherapy or (2) usual care. The primary outcome was self-reported quit rate at 3 months. We performed thematic analysis of participant interview responses. RESULTS: Of 412 people attending between January and March 2020, 115 (27.9%) were current smokers; 46% female, mean (SD) 62.4 (5.3) years. Follow-up data were available for 84 smokers. At 3 months, quit rates in the intervention group were higher 14/48 (29.2%) vs 4/36 (11%) (χ2 3.98, p=0.04). Participant interviews revealed four smoking-cessation related themes: (1) stress and anxiety, (2) impact of the COVID-19 pandemic, (3) CT scans influencing desire to quit and (4) individual beliefs about stopping smoking. CONCLUSION: The provision of immediate smoking cessation support is associated with a substantial increase in quit rates at 3 months. Further research is needed to investigate longer-term outcomes and to refine future service delivery. TRIAL REGISTRATION NUMBER: ISRCTN12455871.

Comparison of Management and Outcomes of Symptomatic Urolithiasis During the COVID-19 Pandemic to a Comparative Cohort.

OBJECTIVE: To analyze the clinical presentation and outcomes for patients who presented with symptomatic urolithiasis during the initial months of the COVID-19 pandemic. METHODS: We retrospectively reviewed Emergency Department (ED) presentations from a Philadelphia healthcare system for symptomatic urolithiasis between March and June 2020 and compared these with presentations for the same time period from the year prior. Patient demographics, stone characteristics, management, and clinical outcomes were compared between the 2 years. RESULTS: One hundred and thirty-nine patients presented during 2020 compared to 269 in 2019. There were fewer patients who presented during the initial COVID-19 pandemic surge who had obesity (37.41% vs 49.44%, P = .024), hyperlipidemia (18.71% vs 31.60, P = .006), and asthma (5.76% vs 16.73%, P = .002). Although overall stone characteristics did not differ between the 2 groups, a larger proportion of patients in 2020 presented with an obstructing stone (81.16% vs 64.1%, P = .001). Patients who presented during the COVID-19 pandemic did not have higher rates of infection, acute kidney injury, or complications. Rates of surgical modalities, emergent procedures, and discharges from the ED were similar between the 2 years. CONCLUSION: The COVID-19 pandemic initial surge resulted in fewer ED presentations for symptomatic urolithiasis; however, patients who did present were more likely to have obstructing stones, perhaps due to delaying presentation to avoid COVID-19 exposure in the ED. Despite higher rates of obstruction, clinical outcomes and morbidity were similar.

Mass spectrometric identification of immunogenic SARS-CoV-2 epitopes and cognate TCRs.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections elicit both humoral and cellular immune responses. For the prevention and treatment of COVID-19, the disease caused by SARS-CoV-2, it has become increasingly apparent that T cell responses are equally if not more important than humoral responses in mediating recovery and immune protection. One major challenge in developing T cell-based therapies for infectious and malignant diseases has been the identification of immunogenic epitopes that can elicit a meaningful T cell response. Traditionally, this has been achieved using sophisticated in silico methods to predict putative epitopes deduced from binding affinities. Our studies find that, in contrast to current convention, "immunodominant" SARS-CoV-2 peptides defined by such in silico methods often fail to elicit T cell responses recognizing naturally presented SARS-CoV-2 epitopes. We postulated that immunogenic epitopes for SARS-CoV-2 are best defined empirically by directly analyzing peptides eluted from the naturally processed peptide-major histocompatibility complex (MHC) and then validating immunogenicity by determining whether such peptides can elicit T cells recognizing SARS-CoV-2 antigen-expressing cells. Using a tandem mass spectrometry approach, we identified epitopes derived from not only structural but also nonstructural genes in regions highly conserved among SARS-CoV-2 strains, including recently recognized variants. Finally, there are no reported T cell receptor-engineered T cell technology that can redirect T cell specificity to recognize and kill SARS-CoV-2 target cells. We report here several SARS-CoV-2 epitopes defined by mass spectrometric analysis of MHC-eluted peptides, provide empiric evidence for their immunogenicity, and demonstrate engineered TCR-redirected killing.

Enabling online determination of the size-dependent RNA content of lipid nanoparticle-based RNA formulations.

The potential of lipid nanoparticles (LNPs) as nucleic acid delivery vehicles has been demonstrated in recent years, culminating in the emergency use approval of LNP-based mRNA SARS-CoV-2 vaccines in late 2020. The determination of RNA content relative to LNP size can be important to the understanding of efficacy and adverse effects. This work presents the first description of a facile and rapid analytical method for online, size-dependent RNA payload distribution measurement using data from multi-angle light scattering, ultraviolet and refractive index detectors following separation of the LNPs by size-exclusion chromatography. The analysis was validated by size-based fractionation of the LNPs with subsequent offline analysis of the fractions. Four LNPs formulated with different PEG-lipids and different lipid compositions were tested. Good agreement was observed between the online and offline size-based RNA distributions among all four LNPs, demonstrating the utility of the online method for LNP-encapsulated RNA in general, and suggesting a means for simplified biophysical quantitation of a dosing-related critical quality attribute.

Relationships between changes in daily occupations and health-related quality of life in persons with multiple sclerosis during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic provided a unique opportunity to explore the impact of the mandated lockdown and social distancing policies on engagement in daily occupations for individuals with multiple sclerosis (MS) and able bodied (i.e. healthy) adults. The study also examined whether the changes in daily occupations were associated with health-related quality of life (HrQOL). METHODS: Between the spring and early fall of 2020, 69 persons with MS and 95 healthy adults completed an online survey that included measurements of 26 activities of daily life. For each activity, participants reported whether they continued to perform the activity (with or without adjustments), whether they stopped, or started to perform the activity during the pandemic. Social support, HrQOL, and demographics, including financial distress were also obtained. RESULTS: Participants with MS and healthy adults both reduced the number of activities performed during the pandemic. Healthy adults continued to do more activities with and without adjustments compared with participants with MS. In both groups, better HrQOL was associated with the number of activities participants continued to do with and without adjustments, and worse HrQOL with the number of activities they stopped doing. CONCLUSIONS: Fewer persons with MS engaged in everyday occupations than healthy adults following the COVID-19 pandemic. The ability to maintain occupational engagement and to participate in social and daily activities is important for maintaining high HrQOL in both groups. Thus, these results call for attention in treatment and self-management of MS symptomatology.

Echocardiography Abnormal Findings and Laboratory Operations during the COVID-19 Pandemic at a High Volume Center in New York City.

(1) Background: This study sought to explore how the novel coronavirus (COVID-19) pandemic affected the echocardiography (TTE) laboratory operations at a high volume medical center in New York City. Changes in cardiac imaging study volume, turn-around time, and abnormal findings were analyzed and compared to a pre-pandemic period. (2) Methods: Volume of all cardiac imaging studies and TTE reports between 11 March 2020 to 5 May 2020 and the same calendar period in 2019 were retrospectively identified and compared. (3) Results: During the pandemic, our center experienced a 46.72% reduction in TTEs, 82.47% reduction in transesophageal echocardiograms, 83.16% reduction in stress echo, 70.32% reduction in nuclear tests, 46.25% reduction in calcium score, 73.91% reduction in coronary computed tomography angiography, and 87.23% reduction in cardiac magnetic resonance imaging. TTE findings were overall similar between 2020 and 2019 (all p ≥ 0.05), except for a significantly higher right ventricular systolic pressure in 2020 (39.8 ± 14.2 vs. 34.6 ± 11.2 mmHg, p = 0.012). (4) Conclusions: Despite encountering an influx of critically ill patients, our hospital center experienced a reduction in the number of cardiac imaging studies, which likely represents a change in both patient mindset and physician management approach.

Clinical evaluation of fever-screening thermography: impact of consensus guidelines and facial measurement location.

SIGNIFICANCE: Infrared thermographs (IRTs) have been used for fever screening during infectious disease epidemics, including severe acute respiratory syndrome, Ebola virus disease, and coronavirus disease 2019 (COVID-19). Although IRTs have significant potential for human body temperature measurement, the literature indicates inconsistent diagnostic performance, possibly due to wide variations in implemented methodology. A standardized method for IRT fever screening was recently published, but there is a lack of clinical data demonstrating its impact on IRT performance. AIM: Perform a clinical study to assess the diagnostic effectiveness of standardized IRT-based fever screening and evaluate the effect of facial measurement location. APPROACH: We performed a clinical study of 596 subjects. Temperatures from 17 facial locations were extracted from thermal images and compared with oral thermometry. Statistical analyses included calculation of receiver operating characteristic (ROC) curves and area under the curve (AUC) values for detection of febrile subjects. RESULTS: Pearson correlation coefficients for IRT-based and reference (oral) temperatures were found to vary strongly with measurement location. Approaches based on maximum temperatures in either inner canthi or full-face regions indicated stronger discrimination ability than maximum forehead temperature (AUC values of 0.95 to 0.97 versus 0.86 to 0.87, respectively) and other specific facial locations. These values are markedly better than the vast majority of results found in prior human studies of IRT-based fever screening. CONCLUSION: Our findings provide clinical confirmation of the utility of consensus approaches for fever screening, including the use of inner canthi temperatures, while also indicating that full-face maximum temperatures may provide an effective alternate approach.

Work in the Time of Coronavirus Belabored Stories

As the COVID-19 pandemic spread, it became clear that for many in business and government, working people are worth only what we can contribute to the accumulation of profits;if we're not productive, we're expendable. While many have been forced to stay home and worry about how to pay the bills, others are working longer and harder in newly dangerous conditions. Since March, we have been collecting short stories about what workers are facing during the crisis, and how they have been fighting back, eight of which you can read here.

The Difficult Airway and Aerosol-Generating Procedures in COVID-19: Timeless Principles for Uncertain Times.

The impact of the COVID-19 pandemic on otolaryngology practice is nowhere more evident than in acute airway management. Considerations of preventing SARS-CoV-2 transmission, conserving personal protective equipment, and prioritizing care delivery based on acuity have dictated clinical decision making in the acute phase of the pandemic. With transition to a more chronic state of pandemic, heightened vigilance is necessary to recognize how deferral of care in patients with tenuous airways and COVID-19 infection may lead to acute airway compromise. Furthermore, it is critical to respect the continuing importance of flexible laryngoscopy in diagnosis. Safely managing airways during the pandemic requires thoughtful multidisciplinary planning. Teams should consider trade-offs among aerosol-generating procedures involving direct laryngoscopy, supraglottic airway use, fiberoptic intubation, and tracheostomy. We share clinical cases that illustrate enduring principles of acute airway management. As algorithms evolve, time-honored approaches for diagnosis and management of acute airway pathology remain essential in ensuring patient safety.
