Less About Privacy: Revisiting a Survey about the German COVID-19 Contact Tracing App

The release of COVID-19 contact tracing apps was accompanied by a heated public debate with much focus on privacy concerns, e.g., possible government surveillance. Many papers studied people's intended behavior to research potential features and uptake of the apps. Studies in Germany conducted before the app's release, such as that by Häring et al., showed that privacy was an important factor in the intention to install the app. We conducted a follow-up study two months post-release to investigate the intention-behavior-gap, see how attitudes changed after the release, and capture reported behavior. Analyzing a quota sample (n=837) for Germany, we found that fewer participants mentioned privacy concerns post-release, whereas utility now plays a greater role. We provide further evidence that the results of intention-based studies should be handled with care when used for prediction purposes. © 2023 ACM.

Antibody Response to SARS-COV-2 Vaccination in Healthcare Workers of Uttarakhand: A Prospective Follow-up Study

Background: Countries around the world are now racing to vaccinate people against SARS-CoV-2, the virus that causes COVID-19. The Government of India also rolled out its vaccination drive from 16th January '2021. Aims: To estimate the antibody response of the COVID-19 vaccine in the form of SARS-COV-2 IgG antibodies in vaccinated healthcare workers.Methods: Prospective follow-up was study conducted on healthcare workers (HCWs) of a Medical college in Dehradun, Uttarakhand. Healthcare workers who have been vaccinated for COVID-19 were tested for SARS-CoV-2-IgG antibodies at regular intervals i.e at 4 weeks after the 1st dose and then again at 4 weeks after the 2nd dose. The third sample was taken 6 months after the 2nd dose. Results: A total of 302 HCWs were enrolled in the study who gave their samples for IgG antibody estimation after the Covishield vaccine. After 4 weeks of completion of both doses, 96% HCWs formed SARS-COV-2 IgG antibodies, whereas 4% didn't. Then after 6 months of follow-up, 14% HCWs have become negative for antibodies and better immunity is seen in people who also got infected with COVID-19 during this time.Conclusion: This study concludes that the immunity gained after vaccination is waning off in around 6 months and there is a need for a booster dose, especially for people at high risk. The infection control practices still play a crucial role in the prevention of this deadly disease.

Long-term respiratory outcomes after COVID-19: a Brazilian cohort study.

Objective: To investigate the prevalence and risk factors for persistent symptoms up to 12 months after hospital discharge in COVID-19 survivors. Methods: This prospective cohort study included patients with COVID-19 discharged from a university hospital in Brazil. Follow-up was performed 2, 6, and 12 months after discharge. Lung function tests and chest computed tomography (CT) were performed 2 months after discharge and were repeated if abnormal. The primary outcomes were the symptoms present, work status, and limitations in daily activities. Results: Eighty-eight patients were included. Dyspnea (54.5%), fatigue (50.0%), myalgia, and muscle weakness (46.6%) were the most common symptoms, which decreased over time. Anxiety was frequent (46.6%) and remained unchanged. One year after discharge, 43.2% of the patients reported limitations in daily activities, and 17.6% had not returned to work. Corticosteroid use was significantly associated with dyspnea and limitations in daily activities. Females had an increased risk of fatigue at the 12-month assessment, with marginal significance after multivariable adjustment. Young age and bronchial wall thickening on admission CT were also risk factors for dyspnea at follow-up. The most common lung function abnormalities were reduced diffusion capacity and small airway disease, which partially improved over time. Conclusions: One year after hospital discharge, more than one-third of patients still had persistent COVID-19-related symptoms, remarkable dyspnea, fatigue, and limitations in daily activities, regardless of acute disease severity. Age, female sex, corticosteroid use during hospitalization, and bronchial thickening on admission CT were associated with an increased risk of sequelae.

Long-Term Sequelae of severe COVID-19: Outpatient assessment of radiological and pulmonary function tests

Objective: Identify lung sequelae of COVID-19 through radiological and pulmonary function assessment. Design(s): Prospective, longitudinal, cohort study from March 2020 to March 2021. Setting(s): Intensive Care Units (ICU) in a tertiary hospital in Portugal. Patient(s): 254 patients with COVID-19 admitted to ICU due to respiratory illness. Intervention(s): A chest computed tomography (CT) scan and pulmonary function tests (PFT) were performed at 3 to 6 months. Main variables of interest: CT-scan;PFT;decreased diffusion capacity of carbon monoxide (DLCO). Result(s): All CT scans revealed improvement in the follow-up, with 72% of patients still showing abnormalities, 58% with ground glass opacities and 62% with evidence of fibrosis. PFT had abnormalities in 94 patients (46%): thirteen patients (7%) had an obstructive pattern, 35 (18%) had a restrictive pattern, and 58 (30%) had decreased DLCO. There was a statistically significant association between abnormalities in the follow-up CT scan and older age, more extended hospital and ICU stay, higher SAPS II and APACHE scores and invasive ventilation. Mechanical ventilation, especially with no lung protective parameters, was associated with abnormalities in PFT. Multivariate regression showed more abnormalities in lung function with more extended ICU hospitalization, chronic obstructive pulmonary disease (COPD), chronic kidney disease, invasive mechanical ventilation, and ventilation with higher plateau pressure, and more abnormalities in CT-scan with older age, more extended ICU stay, organ solid transplants and ventilation with higher positive end-expiratory pressure (PEEP). Conclusion(s): Most patients with severe COVID-19 still exhibit abnormalities in CT scans or lung function tests three to six months after discharge.Copyright © 2023

The benefits of continuing patient and public involvement as part of a randomised controlled trial during the Covid-19 global pandemic

Patient and public involvement (PPI) in clinical research strengthens the quality and relevance of research, and has been crucial to ensure that researchers continue to investigate relevant and important topics during the global Covid-19 pandemic. The MICE (Mental Health Intervention for Children with Epilepsy) randomised controlled trial relies upon PPI to steer the direction and delivery of the trial, and the PPI Research Advisory Group (RAG) adapted to remote online meetings during the pandemic. This article first describes how the PPI RAG supported the research trial during the course of the pandemic, particularly with key trial stages of recruitment, retention and follow-up. It considers how the PPI tasks were adapted to ensure that they remained meaningful throughout this period, particularly for children and young people. Second, the article explores the acceptability of PPI in research using teleconferencing methods, via a co-produced survey of the PPI group members. Survey results indicated that, while participants valued face-to-face meetings, having remote PPI meetings was preferable to having nothing. There was some suggestion that teleconferencing platforms make it challenging for reserved members of the group, and for children, to contribute. Our findings emphasise the importance of continuing PPI even when circumstances are sub-optimal. We hope that our findings will contribute to the wider conversation about what makes PPI effective, particularly in a digital world.

Influence of Deep Sedation in Intensive Care Medicine Memories of Critical COVID-19 Survivors.

Introduction: Critical care survivors sustain a variety of sequelae after intensive care medicine (ICM) admission, and the Coronavirus Disease 2019 (COVID-19) pandemic has added further challenges. Specifically, ICM memories play a significant role, and delusional memories are associated with poor outcomes post-discharge including a delayed return to work and sleep problems. Deep sedation has been associated with a greater risk of perceiving delusional memories, bringing a move toward lighter sedation. However, there are limited reports on post-ICM memories in COVID-19, and influence of deep sedation has not been fully defined. Therefore, we aimed to evaluate ICM-memory recall in COVID-19 survivors and their relation with deep sedation. Materials/Methods: Adult COVID-19 ICM survivors admitted to a Portuguese University Hospital between October 2020 and April 2021 (second/third "waves") were evaluated 1 to 2 months post-discharge using "ICU Memory Tool," to assess real, emotional, and delusional memories. Results: The study included 132 patients (67% male; median age = 62 years, Acute Physiology and Chronic Health Evaluation [APACHE]-II = 15, Simplified Acute Physiology Score [SAPS]-II = 35, ICM stay = 9 days). Approximately 42% received deep sedation (median duration = 19 days). Most participants reported real (87%) and emotional (77%) recalls, with lesser delusional memories (36.4%). Deeply sedated patients reported significantly fewer real memories (78.6% vs 93.4%, P = .012) and increased delusional memories (60.7% vs 18.4%, P < .001), with no difference in emotional memories (75% vs 80.4%, P = .468). In multivariate analysis, deep sedation had a significant, independent association with delusional memories, increasing their likelihood by a factor of approximately 6 (OR = 6.274; 95% confidence interval = 1.165-33.773, P = .032), without influencing real (P = .545) or emotional (P = .133) memories. Conclusions: This study contributes to a better understanding of the potential adverse effects of deep sedation on ICM memories in critical COVID-19 survivors, indicating a significant, independent association with the incidence of delusional recalls. Although further studies are needed to support these findings, they suggest that strategies targeted to minimize sedation should be favored, aiming to improve long-term recovery.

Telephonic Follow-up and the Risk of Death in Ambulatory Patients with COVID-19.

BACKGROUND: Primary care level close monitoring of mild COVID-19 patients has shown to provide a risk reduction in hospitalization and death. We aimed to compare the risk of all-cause death among COVID-19 ambulatory patients who received and did not receive telephonic follow-up in primary health care settings. METHODS: A secondary database analysis, 2-group comparative study, was conducted with data from the medical information systems of the Mexican Institute of Social Security. A total of 1,498,808 ambulatory patients aged 20 years old and over and with laboratory confirmed SARS-CoV-2 by PCR or rapid antigen test were analyzed. Of them, 535,898 (35.8%) where followed by telephonic calls. The cases were attended from October 14, 2020, to April 10, 2022. Death incidence was evaluated. To assess the association between death and telephonic follow-up we calculated risk ratio using a multivariate logistic model. RESULTS: Case fatality rate was 1.29% in the patients who received telephonic follow-up and 2.95% in the cases who did not receive phone calls. Medical history of chronic kidney disease, COPD, cardiovascular disease, tobacco consumption and diabetes were associated with increased risk of death. In the multivariate model, telephonic follow-up was associated with lower risk of all-cause death, with an adjusted risk ratio of 0.61 (95% confidence interval from 0.59, 0.64). CONCLUSION: Our data suggest that telephonic follow-up is associated with a risk of death reduction in adult outpatients with mild COVID-19, in the context of a multimodal strategy in the primary health care settings.

Long-Term Follow-Up Study of COVID-19: Evaluation on Thin-Slice CT.

Purpose: To retrospectively analyse the CT imaging during the long-term follow-up of COVID-19 patients after discharge. Patients and Methods: A total of 122 patients entered the study group. All patients underwent CT examinations. The CT images, which included distribution and imaging signs, were evaluated by two chest radiologists. Laboratory examinations included routine blood work, biochemical testing, and SARS-CoV-2 antibody screening. Statistical methods include chi-square, Fisher's exact test, one-way analysis of variance, rank sum test and logistic regression by SPSS 17.0. Results: There were 22 (18.0%) patients in the mild group, 74 (60.7%) patients in the moderate group, and 26 (21.3%) patients in the severe-critical group. The median follow-up interval was 405 days (378.0 days, 462.8 days). Only monocytes, prothrombin activity, and γ-glutamyltransferase showed significant differences among the three groups. We found that the more severe the patient's condition, the more SARS-CoV-2 IgG antibodies existed. Only 11 patients (11.0%) showed residual lesions on CT. The CT manifestations included irregular linear opacities in nine cases (9.0%), reticular patterns in six cases (6.0%), and GGOs in five cases (5.0%). Conclusion: The proportion of residual lesions on CT in COVID-19 patients was significantly reduced after long-term follow-up. The patients' age and disease conditions were positively correlated with residual lesions.

The Relationship between Mental and Physical Health and Walking during the COVID-19 Pandemic

Introduction: COVID-19 policies such as quarantining, social isolation, and lockdowns are an essential public health measure to reduce the spread of disease but may lead to reduced physical activity. Little is known if these changes are associated with changes in physical or mental health. Method(s): Between September 2017 and December 2018 (baseline) and March 2020 and February 2021 (follow-up), we obtained self-reported demographic, health, and walking (only at follow-up) data on 2042 adults in primary care with multiple chronic health conditions. We examined whether the perceived amount of time engaged in walking was different compared with prepandemic levels and if this was associated with changes in Patient-Reported Outcomes Measurement Information System-29 mental and physical health summary scores. Multivariable linear regression controlling for demographic, health, and neighborhood information were used to assess this association. Result(s): Of the 2042 participants, 9% reported more walking, 28% reported less, and 52% reported the same amount compared with prepandemic levels. Nearly 1/3 of participants reported less walking during the pandemic. Multivariable models revealed that walking less or not at all was associated with negative changes in mental (s = -1.0;95% CI [-1.6, -0.5];s = -2.2;95% CI [-2.9, -1.4]) and physical (s = -0.9;95% CI [-1.5, -0.3];s = -3.1;95% CI [-4.0, -2.3]) health, respectively. Increasing walking was significantly associated with a positive change in physical health (s = 1.3;95% CI [0.3, 2.2]). Conclusion(s): These findings demonstrate the importance of walking during the COVID-19 pandemic. Promotion of physical activity should be taken into consideration when mandating restrictions to slow the spread of disease. Primary care providers can assess patient's walking patterns and implement brief interventions to help patients improve their physical and mental health through walking.

One-Year Mental and Physical Health Assessment in Survivors After ECMO for COVID-19-related ARDS.

RATIONAL: Long-term outcomes of patients with COVID-19-related acute respiratory distress syndrome (ARDS) treated with extracorporeal membrane oxygenation (ECMO) are unknown. METHODS: Multicenter, prospective study in patients who received ECMO for COVID-19 ARDS from March to June 2020 and survived hospital discharge. Physical examination, pulmonary function tests, anxiety, depression, post-traumatic stress disorders (PTSD), and quality of life (QoL) were assessed at 6 and 12 months after ECMO onset. RESULTS: Of 80 eligible patients, 62 were enrolled in 7 French Intensive Care Units (ICU). ECMO and invasive mechanical ventilation duration were 18 (11-25) and 36 (27-62) days, respectively. All were alive but only 19/50 (38%) returned to work and 13/42 (31%) had recovered a normal sex drive at one year. Pulmonary function tests were almost normal at 6 months except for diffusing capacity for carbon monoxide which was still impaired at 12 months. Mental health, role-emotional, and role-physical were the most impaired domain compared to non-COVID ECMO patients. One year after ICU admission, 19/43 (44%) patients had significant anxiety, 18/43 (42%) had depression symptoms and 21/50 (42%) were at risk for PTSD. CONCLUSIONS: Despite the partial recovery of the lung function tests at one year, the physical and psychological function of this population remains impaired. Based on the comparison with long-term follow-up of non-COVID ECMO patients, poor mental and physical health may be more related to COVID-19 than to ECMO in itself, although this needs confirmation This article is open access and distributed under the terms of the Creative Commons Attribution Non-Commercial No Derivatives License 4.0 (http://creativecommons.org/licenses/by-nc-nd/4.0/).

Burnout and Commitment After 18 Months of the COVID-19 Pandemic: A Follow-Up Qualitative Study with Primary Care Teams.

BACKGROUND: Primary care practice teams continue to grapple with the demands of the COVID-19 pandemic. Early in the pandemic, despite the increased demands and low levels of control, in practices where protective equipment were available and practice-level support was high, few team members reported burnout, and many described a greater sense of purpose. However, since those early days, burnout levels have increased and high rates of turnover have been reported across the health care system, and further qualitative studies are needed. OBJECTIVE: The present study is a follow-up to a qualitative study on the workplace stress during the pandemic. DESIGN, PARTICIPANTS, APPROACH: Fourteen primary care providers and staff completed 1-year follow-up semistructured interviews (approximately 1.5 years into the pandemic) about their workplace demands, control, social support, burnout, and commitment to primary care. PRIMARY RESULTS: Primary care practice was characterized as high demand before the pandemic but the additional demands of the pandemic were leading participants to consider early retirement, quitting primary care or health care, and expressing a profound need for health care redesign. Short staffing extended medical leaves for COVID-19 and non-COVID-19 needs, increased management of patient mental health and aggressive behaviors, and frustration that practices were being held to prepandemic metrics all contributed to ever higher rates of burnout. Troublingly, while many described high-quality relationships at the practice level, the majority of participants described their organization-level support as largely unresponsive to their input and as offering little support or resources, though a few acknowledged that this could reflect that leadership is also under immense strain. Despite challenges, a number of participants expressed continued commitment to primary care. CONCLUSION: Fundamental redesign of primary care is required to prevent further loss of health care personnel and to provide opportunities for these staff to recover during the grueling, ongoing crisis.

Long-term outcomes in COVID-19 patients who recovered from the first wave of the pandemic.

This cross-sectional study evaluated the long-term health effects of coronavirus disease 2019 (COVID-19) in Jianghan District (Wuhan, China). The results showed that 61.4% of COVID-19 patients reported at least one symptom and 8.8% had depressive symptoms at the 17-month follow-up. The proportion of patients with chest radiographic abnormalities in Fangcang shelter hospitals and designated COVID-19 hospitals was 31.6% and 41.1%, respectively, and the proportion of patients with impaired pulmonary diffusion capacity in these hospitals was 52.8% and 60.9%, respectively. Female sex (odds ratio [OR] = 1.48, 95% confidence interval [CI]: 1.16-1.88), severe disease (OR = 1.46, 95% CI: 1.01-2.10) and a higher number of initial symptoms (OR = 1.31, 95% CI: 1.23-1.40) were associated with the development of sequelae symptoms at 17 months. This study involving community-dwelling COVID-19 adults may help determine the long-term effects of COVID-19 during the first pandemic wave. Nonetheless, larger follow-up studies are needed to characterize the post-COVID-19 condition.

Caregiving in the COVID-19 pandemic: Family adaptations following an intensive care unit hospitalisation.

AIM AND OBJECTIVE: To identify how family caregivers adapt to the caregiving role following a relative's COVID-19-related intensive care unit (ICU) hospitalisation. BACKGROUND: Family caregiving is often associated with poor health amongst caregivers which may limit their capacity to effectively support patients. Though severe COVID-19 infection has necessitated increasing numbers of persons who require caregiver support, little is known about these caregivers, the persons they are caring for, or the strategies used to effectively adjust to the caregiving role. DESIGN: A qualitative descriptive study design was adopted, and findings are reported using COREQ. METHODS: A secondary analysis of transcripts from semi-structured interviews conducted with recently discharged ICU patients who had COVID-19 (n = 16) and their family caregivers (n = 16) was completed using thematic analysis. MAXQDA 2020 and Miro were used to organise data and complete coding. Analysis involved a structured process of open and closed coding to identify and confirm themes that elucidated adaptation to family caregiving. RESULTS: Six themes highlight how family caregivers adapt to the caregiving role following an ICU COVID-19-related hospitalisation including (1) engaging the support of family and friends, (2) increased responsibilities to accommodate caregiving, (3) managing emotions, (4) managing infection control, (5) addressing patient independence and (6) engaging support services. These themes were found to be congruent with the Roy adaptation model. CONCLUSIONS: Family caregiving is a stressful transition following a patient's acute hospitalisation. Effective adaptation requires flexibility and sufficient support, beginning with the care team who can adequately prepare the family for the anticipated challenges of recovery. RELEVANCE TO CLINICAL PRACTICE: Clinical teams may improve post-hospitalisation care outcomes of patients by preparing families to effectively adjust to the caregiver role-particularly in identifying sufficient support resources. PATIENT OR PUBLIC CONTRIBUTION: Participation of patients/caregivers in this study was limited to the data provided through participant interviews.

The Relationship Between Mental and Physical Health and Walking During the COVID-19 Pandemic.

INTRODUCTION: COVID-19 policies such as quarantining, social isolation, and lockdowns are an essential public health measure to reduce the spread of disease but may lead to reduced physical activity. Little is known if these changes are associated with changes in physical or mental health.

Nearly 1/3 of participants reported less walking during the pandemic. Multivariable models revealed that walking less or not at all was associated with negative changes in mental (ß = -1.0; 95% CI [-1.6, -0.5]; ß = -2.2; 95% CI [-2.9, -1.4]) and physical (ß = -0.9; 95% CI [-1.5, -0.3]; ß = -3.1; 95% CI [-4.0, -2.3]) health, respectively. Increasing walking was significantly associated with a positive change in physical health (ß = 1.3; 95% CI [0.3, 2.2]). CONCLUSIONS: These findings demonstrate the importance of walking during the COVID-19 pandemic. Promotion of physical activity should be taken into consideration when mandating restrictions to slow the spread of disease. Primary care providers can assess patient's walking patterns and implement brief interventions to help patients improve their physical and mental health through walking.

Risk Factors of Readmission in COVID-19 Patients; a Retrospective 6-Month Cohort Study.

Introduction: The available literature regarding the rate of readmission of COVID-19 patients after discharge is rather scarce. Thus, the aim in the current study was to evaluate the readmission rate of COVID-19 patients and the components affecting it, including clinical symptoms and relevant laboratory findings. Methods: In this retrospective cohort study, COVID-19 patients who were discharged from Imam Hossein hospital, Tehran, Iran, were followed for six months. Data regarding their readmission status were collected through phone calls with COVID-19 patients or their relatives, as well as hospital registry systems. Eventually, the relationship between demographic and clinical characteristics and readmission rate was assessed. Results: 614 patients were entered to the present study (mean age 58.7±27.2 years; 51.5% male). 53 patients were readmitted (8.6%), of which 47 patients (7.6%) had a readmission during the first 30 days after discharge. The reasons for readmission were relapse of COVID-19 symptoms and its pulmonary complications in 40 patients (6.5%), COVID-19 related cardiovascular complications in eight patients (1.3%), and non-COVID-19 related causes in five patients (0.8%). Older age (OR=1.04; 95% CI: 1.01, 1.06; p=0.002) and increased mean arterial pressure during the first admission (OR=1.04; 95% CI: 1.01, 1.08; p=0.022) were found to be independent prognostic factors for the readmission of COVID-19 patients. Conclusion: Readmission is relatively frequent in COVID-19 patients. Lack of adequate hospital space may be the reason behind the early discharge of COVID-19 patients. Hence, to reduce readmission rate, extra care should be directed towards the discharge of older or hypertensive patients.

Experiences with online education during COVID-19

Early in spring 2020, universities world-wide suddenly moved their courses online in response to the COVID-19 pandemic. A number of researchers have studied the impact of this sudden move on the mental health and education of the effected students. The Center for Collegiate Mental Health reported that a third of students visited a college counseling center in 2020 due to mental health issues from the pandemic. Sixty eight percent of those seeking services for any reason indicated that the pandemic hurt their "motivation and focus."Sixty six percent indicated that the pandemic had a negative impact on academics. In a follow-up study, the Center found a significant increase in "academic distress"from 2019 to 2020. However, not all researchers found a negative impact. A study of at-risk undergraduates found that moving courses online did not necessarily demotivate disadvantaged students. This paper provides another view of the impact of moving courses online. The test performance of five semesters of a Computer Systems course is examined;in two of those semesters the course was offered online due to the pandemic. In addition, students in one online section were surveyed to determine what aspects, if any, of the online course should be retained after the course resumed face-To-face. Our study found that a larger percentage of the students in the online sections failed the tests and an analysis of test results confirms, with a 90% confidence, that overall online learners score at least 5 points lower on tests. In addition, in a survey of students in one online section, students reported that they felt their grades would have been higher had the course been face-To-face. However, most students reported that lab sessions, but not class sessions, should continue to be offered online. © 2022 ACM.

Critical Influenza and COVID-19-A Comparative Nationwide Case-Control Study.

Refined knowledge of risk factors for critical influenza and COVID-19 may lead to improved understanding of pathophysiology and better pandemic preparedness. OBJECTIVES: To compare risk-factor profiles of patients admitted to intensive care with critical influenza and COVID-19. DESIGN SETTING AND PATIENTS: A nationwide retrospective matched case-control study, including all adults admitted to an ICU in Sweden with influenza or COVID-19 between 2014 and September 2020 and a matched control population (ratio 1:5, patients:controls). MEASUREMENTS AND MAIN RESULTS: Admission to an ICU. The study included 1,873 influenza and 2,567 COVID-19 ICU patients, and 9,365 and 12,835 controls, respectively, matched on sex, age, and geographical region. Influenza patients were older and less likely male, and carried a larger burden of comorbidity and a higher Simplified Acute Physiology Score III score, whereas short-term mortalities were similar when compared to COVID-19 patients. The risk-factor profiles at ICU admission were largely comparable including socioeconomic, psychiatric, and several somatic variables. Hypertension was a strong risk factor in critical COVID-19 patients compared with influenza. Nonglucocorticoid immunosuppressive therapy was associated with critical influenza but not COVID-19. Premorbid medication with statins and renin-angiotensin-aldosterone system inhibitors reduced the risk for both conditions, the opposite was a seen for glucocorticoid medication. Notably, medication with betablockers, oral anticoagulation, and platelet inhibitors reduced the risk of critical COVID-19 but not influenza. CONCLUSIONS: The risk-factor profiles for critical influenza and COVID-19 were largely comparable; however, some important differences were noted. Hypertension was a stronger risk factor for developing critical COVID-19, whereas the use of betablockers, oral anticoagulants, and platelet inhibitors all reduced the risk of ICU admission for COVID-19 but not influenza. Findings possibly reflected differences in pathophysiological mechanisms between these conditions.

COVID-19 in Patients with Glomerular Disease: Follow-Up Results from the IRoc-GN International Registry.

Background: The acute and long-term effects of severe acute respiratory syndrome coronavirus 2 infection in individuals with GN are still unclear. To address this relevant issue, we created the International Registry of COVID-19 infection in GN. Methods: We collected serial information on kidney-related and -unrelated outcomes from 125 GN patients (63 hospitalized and 62 outpatients) and 83 non-GN hospitalized patients with coronavirus disease 2019 (COVID-19) and a median follow-up period of 6.4 (interquartile range 2.3-9.6) months after diagnosis. We used logistic regression for the analyses of clinical outcomes and linear mixed models for the longitudinal analyses of eGFR. All multiple regression models were adjusted for age, sex, ethnicity, and renin-angiotensin-aldosterone system inhibitor use. Results: After adjustment for pre-COVID-19 eGFR and other confounders, mortality and AKI did not differ between GN patients and controls (adjusted odds ratio for AKI=1.28; 95% confidence interval [CI], 0.46 to 3.60; P=0.64). The main predictor of AKI was pre-COVID-19 eGFR (adjusted odds ratio per 1 SD unit decrease in eGFR=3.04; 95% CI, 1.76 to 5.28; P<0.001). GN patients developing AKI were less likely to recover pre-COVID-19 eGFR compared with controls (adjusted 6-month post-COVID-19 eGFR=0.41; 95% CI, 0.25 to 0.56; times pre-COVID-19 eGFR). Shorter duration of GN diagnosis, higher pre-COVID-19 proteinuria, and diagnosis of focal segmental glomerulosclerosis or minimal change disease were associated with a lower post-COVID-19 eGFR. Conclusions: Pre-COVID-19 eGFR is the main risk factor for AKI regardless of GN diagnosis. However, GN patients are at higher risk of impaired eGFR recovery after COVID-19-associated AKI. These patients (especially those with high baseline proteinuria or a diagnosis of focal segmental glomerulosclerosis or minimal change disease) should be closely monitored not only during the acute phases of COVID-19 but also after its resolution.

Teledermatology versus Face-to-Face Dermatology: An Analysis of Cost-Effectiveness from Eight Studies from Europe and the United States.

(1) Background: The aim of this systematic review was to compare the cost-effectiveness of two follow-up methods (face-to-face and telemedicine) used in dermatology in the last ten years. (2) Methods: A search for articles that included economic analyses was conducted in August 2021 in the databases PubMed, Medline, Scielo and Scopus using the following keywords: "Cost-Benefit Analysis", "Dermatology", "Telemedicine", "Primary Health Care", as well as other search terms and following the PICOS eligibility criteria. (3) Results: Three clinical trials and five observational studies were analyzed, providing information for approximately 16,539 patients (including four cost-minimization or saving analyses, three cost-effectiveness analyses, and one cost-utility analysis) in Europe and the United States. They describe the follow-up procedures in each of the cases and measure and analyze the direct and indirect costs and effectiveness. All the articles indicate that teledermatology lowers costs and proves satisfactory to both patients and professionals. (4) Conclusions: Although it has been found that follow-up via teledermatology can be more efficient than traditional hospital follow-up, more work is needed to establish evaluation protocols and procedures that measure key variables more equally and demonstrate the quality of the evidence of said studies.

Knowledge Update on the Economic Evaluation of Pacemaker Telemonitoring Systems.

(1) Introduction: In the last two decades, telemedicine has been increasingly applied to telemonitoring (TM) of patients with pacemakers; however, presently, its growth has significantly accelerated because of the COVID-19 pandemic, which has pushed patients and healthcare workers alike to seek new ways to stay healthy with minimal physical contact. Therefore, the main objective of this study was to update the current knowledge on the differences in the medium-and long-term effectiveness of TM and conventional monitoring (CM) in relation to costs and health outcomes. (2) Methods: Three databases and one scientific registry were searched (PubMed, EMBASE, Scopus, and Google Scholar), with no restrictions on language or year of publication. Studies published until July 2021 were included. The inclusion criteria were: (a) experimental or observational design, (b) complete economic evaluation, (c) patients with implanted pacemakers, and (d) comparison of TM with CM. Measurements of study characteristics (author, study duration, sample size, age, sex, major indication for implantation, and pacemaker used), analysis, significant results of the variables (analysis performed, primary endpoints, secondary endpoints, health outcomes, and cost outcomes), and further miscellaneous measurements (methodological quality, variables coded, instrument development, coder training, and intercoder reliability, etc.) were included. (3) Results: 11 studies met the inclusion criteria, consisting of 3372 enrolled patients; 1773 (52.58%) of them were part of randomized clinical trials. The mean age was 72 years, and the atrioventricular block was established as the main indication for device implantation. TM was significantly effective in detecting the presence or absence of pacemaker problems, leading to a reduction in the number of unscheduled hospital visits (8.34-55.55%). The cost of TM was up to 87% lower than that of CM. There were no significant differences in health-related quality of life (HRQoL) and the number of cardiovascular events. (4) Conclusions: Most of the studies included in this systematic review confirm that in the TM group of patients with pacemakers, cardiovascular events are detected and treated earlier, and the number of unscheduled visits to the hospital is significantly reduced, without affecting the HRQoL of patients. In addition, with TM modality, both formal and informal costs are significantly reduced in the medium and long term.
