    Title translation Komorbidität bei Kindern mit COVID-19 und MIS-C/PIMS-TS und Risikofaktoren für Hospitalisierung, schweren Krankheitsverlauf, Intensivtherapie und Tod.
    Abstract This narrative review sums up data from the SARS-CoV-2-pandemia on preexisting disease/underlying conditions/comorbidities and risk factors in children for severe COVID-19 and MIS-C/PIMS-TS as well as hospitalization and mortality. Young infants and adolescents are at highest risk of hospital and PICU admission. Two or more comorbidities rather than single entities pose a risk for more severe courses of SARS-CoV-2 infection in children. Asthma and malignancy do not increase complication rates. MIS-C/PIMS-TS is not associated with any specific underlying disease.

    Abstract Objectives: The COVID-19 pandemic resulted in rapid reorganisations of hospital care. In our hospital, the geriatrics team introduced the Clinical Frailty Scale (CFS) on the non-ICU COVID-19 units during these reorganisations. A retrospective analysis was performed to investigate the CFS as a risk factor for severe COVID-19 disease and in-hospital death in older patients with COVID-19.
    Methods: In patients aged ≥70 years, an online geriatric assessment questionnaire was launched, from which the CFS was scored by the geriatrics team. Additional clinical data were collected from the electronic medical records. Risk factors related to ageing, such as the CFS, age-adjusted Charlson Comorbidity Index, living situation and cognitive decline, were examined alongside frequently reported risk factors in the general population. Outcomes were in-hospital death (primary outcome) and oxygen need of ≥6 litres and early warning score ≥7, as parameters for severe disease (secondary outcomes). Baseline characteristics were described with descriptive statistics. Associations were analysed with uni- and multivariable analyses.
    Results: One hundred and five patients were included, median age 82 years. CFS scores were 1-4 in 43, 5-6 in 45, and 7-9 in 17 patients. In multivariable analysis, CFS and cognitive decline were the only risk factors that were independently associated with in-hospital mortality. Chronic obstructive pulmonary disease, presence of respiratory symptoms on admission and male gender showed and independent association with severe disease.
    Conclusion: A retrospective analysis shows that CFS and cognitive decline have added value for predicting in-hospital mortality in older patients with COVID-19 disease.

    Abstract Objective: The aim of this study was to provide a comprehensive evidence on risk factors for transmission, disease severity and COVID-19 related deaths in Africa.
    Design: A systematic review has been conducted to synthesise existing evidence on risk factors affecting COVID-19 outcomes across Africa.
    Data sources: Data were systematically searched from MEDLINE, Scopus, MedRxiv and BioRxiv.
    Eligibility criteria: Studies for review were included if they were published in English and reported at least one risk factor and/or one health outcome. We included all relevant literature published up until 11 August 2020.
    Data extraction and synthesis: We performed a systematic narrative synthesis to describe the available studies for each outcome. Data were extracted using a standardised Joanna Briggs Institute data extraction form.
    Results: Fifteen articles met the inclusion criteria of which four were exclusively on Africa and the remaining 11 papers had a global focus with some data from Africa. Higher rates of infection in Africa are associated with high population density, urbanisation, transport connectivity, high volume of tourism and international trade, and high level of economic and political openness. Limited or poor access to healthcare are also associated with higher COVID-19 infection rates. Older people and individuals with chronic conditions such as HIV, tuberculosis and anaemia experience severe forms COVID-19 leading to hospitalisation and death. Similarly, high burden of chronic obstructive pulmonary disease, high prevalence of tobacco consumption and low levels of expenditure on health and low levels of global health security score contribute to COVID-19 related deaths.
    Conclusions: Demographic, institutional, ecological, health system and politico-economic factors influenced the spectrum of COVID-19 infection, severity and death. We recommend multidisciplinary and integrated approaches to mitigate the identified factors and strengthen effective prevention strategies.

    Abstract Background: Knowledge of COVID-19 epidemiology remains incomplete and crucial questions persist. We aimed to examine risk factors for COVID-19 death.
    Methods: A total of 80 543 COVID-19 cases reported in China, nationwide, through 8 April 2020 were included. Risk factors for death were investigated by Cox proportional hazards regression and stratified analyses.
    Results: Overall national case-fatality ratio (CFR) was 5.64%. Risk factors for death were older age (≥80: adjusted hazard ratio, 12.58; 95% confidence interval, 6.78-23.33), presence of underlying disease (1.33; 1.19-1.49), worse case severity (severe: 3.86; 3.15-4.73; critical: 11.34; 9.22-13.95), and near-epicenter region (Hubei: 2.64; 2.11-3.30; Wuhan: 6.35; 5.04-8.00). CFR increased from 0.35% (30-39 years) to 18.21% (≥70 years) without underlying disease. Regardless of age, CFR increased from 2.50% for no underlying disease to 7.72% for 1, 13.99% for 2, and 21.99% for ≥3 underlying diseases. CFR increased with worse case severity from 2.80% (mild) to 12.51% (severe) and 48.60% (critical), regardless of region. Compared with other regions, CFR was much higher in Wuhan regardless of case severity (mild: 3.83% vs 0.14% in Hubei and 0.03% elsewhere; moderate: 4.60% vs 0.21% and 0.06%; severe: 15.92% vs 5.84% and 1.86%; and critical: 58.57% vs 49.80% and 18.39%).
    Conclusions: Older patients regardless of underlying disease and patients with underlying disease regardless of age were at elevated risk of death. Higher death rates near the outbreak epicenter and during the surge of cases reflect the deleterious effects of allowing health systems to become overwhelmed.

    Abstract Introduction: Progression of COVID-19 to severe disease and death is insufficiently understood. Objective: Summarize the prevalence adverse outcomes, risk factors, and association of risk factors with adverse outcomes in COVID-19 patients. Methods: We searched Medline, Embase and Web of Science for case-series and observational studies of hospitalized COVID-19 patients through May 22, 2020. Data were analyzed by fixed-effects meta-analysis, using Shore adjusted confidence intervals to address heterogeneity. Results: Forty-four studies comprising 20594 hospitalized patients met inclusion criteria; 12591 from the US-Europe and 7885 from China. Pooled prevalence of death [%(95% CI)] was 18% (15-22%). Of those that died, 76% were aged>=60 years, 68% were males, and 63%, 38%, and 29% had hypertension, diabetes and heart disease, respectively. The case fatality risk [%(95% CI)] were 62% (48-78) for heart disease, 51% (36-71) for COPD, and 42% (34-50) for age>=60 years and 49% (33-71) for chronic kidney disease (CKD). Summary relative risk (sRR) of death were higher for age>=60 years [sRR=3.8; 95% CI: 2.9-4.8; n=12 studies], males [1.3; 1.2-1.5; 17], smoking history [1.9; 1.1-3.3; n=6], COPD [2.0; 1.6-2.4; n=9], hypertension [1.8; 1.7-2.0; n=14], diabetes [1.5; 1.4-1.7; n=16], heart disease [2.0; 1.7-2.4; 16] and CKD [2.0; 1.3-3.1; 8]. The overall prevalence of hypertension (55%), diabetes (31%) and heart disease (16%) among COVODI-19 patients in the US were substantially higher than the general US population. Conclusions: Public health screening for COVID-19 can be prioritized based on risk-groups. A higher prevalence of cardiovascular risk factors in COVID-19 patients can suggest increased risk of SARS-CoV-2 acquisition in the population.

    Abstract Older age is a major risk factor for adverse outcomes of COVID-19, potentially due to immunosenescence and chronic low-grade inflammation, both characteristics of older adults which synergistically contribute to their vulnerability. Furthermore, older age is also associated with decreased kidney function and is consequently associated with an increased risk of cardiovascular disease. All of this in the course of COVID-19 infection can worsen and promote the progression of chronic kidney damage and all its sequelae. Frailty is a condition characterized by the decline in function of several homeostatic systems, leading to increased vulnerability to stressors and risk of adverse health outcomes. Thus, it is very likely that frailty, together with comorbidities, may have contributed to the high vulnerability to severe clinical manifestations and deaths from COVID-19 among older people. The combination of viral infection and chronic inflammation in the elderly could cause multiple unforeseen harmful consequences, affecting overall disability and mortality rates. In post-COVID-19 patients, inflammation has been implicated in sarcopenia progression, functional activity decline, and dementia. After the pandemic, it is imperative to shine a spotlight on these sequelae so that we can be prepared for the future outcomes of the ongoing pandemic. Here, we discuss the potential long-term consequences of SARS-CoV-2 infection and its possibility of causing permanent damage to the precarious balance existing in the frail elderly with multiple pathologies.

    Abstract Coronaviruses are pathogens thought to primarily affect the respiratory tracts of humans. The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2019 was also marked mainly by its symptoms of respiratory illness, which were named coronavirus disease 2019 (COVID-19). Since its initial discovery, many other symptoms have been linked to acute SARS-CoV-2 infections as well as to the long-term outcomes of COVID-19 patients. Among these symptoms are different categories of cardiovascular diseases (CVDs), which continue to be the main cause of death worldwide. The World Health Organization estimates that 17.9 million people die from CVDs each year, accounting for ∼32% of all deaths globally. Physical inactivity is one of the most important behavioral risk factors for CVDs. The COVID-19 pandemic has affected CVDs as well as the physical activity in different ways. Here, we provide an overview of the current status as well as future challenges and possible solutions.
