REVIEW
Anders Tegnell
The Swedish COVID-19 response has received excessive attention, despite not having distinctively different goals or features than other countries. The overall response has included almost all sectors of society and cannot be described here. Instead, this paper provides a general, brief description of the response from a public health perspective, but hopefully it gives a somewhat more nuanced picture of the efforts to combat COVID-19 in Sweden.

The first wave of the COVID-19 pandemic was characterized by an initial rapid rise in new cases followed by a peak and a more erratic behaviour that varies between regions. This is not easy to reproduce with traditional SIR models, which predict a more symmetric epidemic. Here, we argue that superspreaders and population heterogeneity would predict such behaviour even in the absence of restrictions on social life. We present an agent-based lattice model of a disease spreading in a heterogeneous population. We predict that an epidemic driven by superspreaders will spread rapidly in cities, but not in the countryside where the sparse population limits the maximal number of secondary infections...

In March 2020, the COVID-19 pandemic forced most activities in Italy, including soccer, to cease. During lockdown, players could only train at home, with limited evidence regarding the effect of this period. Therefore, this study aimed to investigate the effect of COVID-19 lockdown on professional soccer players' physical performance. Aerobic fitness and vertical jump were assessed before and after four periods in two different seasons: COVID-19 lockdown, competitive period before lockdown, competitive period and summer break of the 2016-2017 season...

In this review article, current information on the frequency and relevance of chemosensory disorders in Covid-19 was recorded, assigned pathophysiologically and statements on prognostic significance were derived. The results are based on a comprehensive literature search of all literature on this topic and our own experience in the treatment of patients with smell and taste disorders since the beginning of the pandemic.Current study results indicate that clinically less affected Covid-19 patients without inpatient treatment and who do not require ventilation often have disorders of the chemosensory system...

BACKGROUND: Detailed understanding of the immune response to severe acute respiratory syndrome coronavirus (SARS-CoV)-2, the cause of coronavirus disease 2019 (CO-VID-19) has been hampered by a lack of quantitative antibody assays. OBJECTIVE: The objective was to develop a quantitative assay for IgG to SARS-CoV-2 proteins that could be implemented in clinical and research laboratories. METHODS: The biotin-streptavidin technique was used to conjugate SARS-CoV-2 spike receptor-binding domain (RBD) or nucleocapsid protein to the solid phase of the ImmunoCAP...

COVID-19 is a serious disease that has infected more than 40 million people. Beside significant mortality, the SARS-CoV-2 infection causes considerable and sustained morbidity, dubbed long COVID. This paper argues that some of this morbidity may be due to a persistent systemic infection. Persistent infection is indicated by continued virus RNA shedding. The virus' superantigen could overstimulate anti-virus immune responses, and thereby induce negative feedback loops, that paradoxically allow the virus to persist...

INTRODUCTION: Children account for a relatively small proportion of laboratory-confirmed SARS-CoV-2 infections. In children, COVID-19 usually has a relatively mild course. However, in rare cases, severe disorders can be observed, and clinical manifestations may differ from adults. PURPOSE: The aim of this study is to analyse the frequency, clinical picture and outcome of COVID-19 in children based on the experience from the tertiary care centre and regional sanitary-epidemiological office...

INTRODUCTION: Coronavirus disease 2019 or COVID-19 is a new infectious disease responsible for potentially severe respiratory impairment associated with initial immunosuppression. Similarly to influenza, several authors have described a higher risk of fungal infection after COVID-19, in particular for invasive pulmonary aspergillosis. The main objective here is to define the prevalence of invasive pulmonary aspergillosis (IPA) in a cohort of COVID-19 patients with moderate to severe acute respiratory disease syndrome (ARDS)...

BACKGROUND: The outbreak of the COVID-19 pandemic influenced family-centred care dramatically due to restricting visiting policies. In this new situation, nurses were challenged to develop new approaches to involve family members in patient care. A better understanding of these changes and the experiences of nurses is essential to make an adaptation of procedures, and to secure a family-centred approach in care as much as possible. OBJECTIVES: The aim of this study was to investigate how family involvement had taken place, and to explore the experiences of nurses with family involvement during the COVID-19 outbreak...

Corona virus disease 2019 (COVID-19) is a global emergency able to overwhelm the healthcare capacities worldwide and to affect the older generation especially. When addressing the pathophysiological mechanisms and clinical manifestations of COVID-19, it becomes evident that the disease targets pathways and domains affected by the main aging- and frailty-related pathophysiological changes. A closer analysis of the existing data supports a possible role of biological age rather than chronological age in the prognosis of COVID-19...

BACKGROUND: The newly emerged severe acute respiratory syndrome coronavirus (SARS-CoV-2) has caused a worldwide pandemic of human respiratory disease. Angiotensin-converting enzyme (ACE) 2 is the key receptor on lung epithelial cells to facilitate initial binding and infection of SARS-CoV-2. The binding to ACE2 is mediated via the spike glycoprotein present on the viral surface. Recent clinical data have demonstrated that patients with previous episodes of brain injuries are a high-risk group for SARS-CoV-2 infection...

BACKGROUND: Severity of illness in COVID-19 is consistently lower in women. Focus on sex as a biologic factor may suggest a potential therapeutic intervention for this disease. We assessed whether adding progesterone to standard of care would improve clinical outcomes of hospitalized men with moderate to severe COVID-19. RESEARCH QUESTION: Does short-term subcutaneous administration of progesterone safely improve clinical outcome in hypoxemic men hospitalized with COVID-19? STUDY DESIGN AND METHODS: We conducted a pilot, randomized, open-label, controlled trial of subcutaneous progesterone in men hospitalized with confirmed moderate to severe COVID-19...
