Covid19-Sources

DMZ – POLITIK / WISSEN / GESUNDHEIT ¦ AA ¦ Der Beitrag im "Pandemic Accountability Index" (Pandemie-Verantwortlichkeitsindex) vom letzten November, in dem über hundert Studien und Artikel zu den Auswirkungen des SARS-CoV-2-Virus auf den Körper berichtet wurde, ist mittlerweile über sechs Monate alt. Seitdem wurden weitere Forschungsergebnisse veröffentlicht. Es ist daher an der Zeit, unser Verständnis dafür zu aktualisieren, warum es so wichtig ist, Infektionen mit diesem gefährlichen und behindernden Virus zu verhindern. Laut der Weltgesundheitsorganisation (WHO) leiden allein in Europa über 36 Millionen Menschen an Langzeitfolgen von COVID, einem Oberbegriff für zahlreiche medizinische Komplikationen. Diejenigen, die behauptet haben, dass SARS-CoV-2 relativ harmlos oder "mild" sei und COVID-19 "nur eine Erkältung/Grippe" sei, müssen sich mit der ständig wachsenden Anzahl wissenschaftlicher Forschungsergebnisse auseinandersetzen, die seitdem veröffentlicht wurden. Kinder und COVID: COVID-19 ist eine der häufigsten Todesursachen bei Kindern und Jugendlichen in den USA (University of Oxford). Anstieg von Diabetes bei Kindern und Jugendlichen (Jama Network). Auch milde Infektionen können zu langfristigen Folgen führen, einschließlich Long-COVID (University of Minnesota). Mehr als 70% der Haushaltsübertragungen von COVID in den USA gehen von Kindern aus (CIDRAP). Kinder können nach einer asymptomatischen oder milden COVID-19-Erkrankung langfristige Herzmuskeldeformationen entwickeln (MDPI Open Access Journals). Langzeitfolgen bei Jugendlichen und jungen Erwachsenen nach mildem COVID-19 (Frontiers in Immunology). Einige Kinder zeigen nach einer COVID-19-Infektion Symptome wie Fieber, Erbrechen und Augenschmerzen (NHK). COVID-19 kann bei Kindern autoimmune Reaktionen auslösen (HCPLive). Erhöhte Raten von Asthma, Myokarditis, Diabetes und anderen Erkrankungen bei Kindern mit bestätigtem COVID-19 (Medical Journal of Australia). Über 30% der Kinder zeigen auch nach 2 Monaten noch Symptome, und 2,3% haben nach 6 Monaten immer noch anhaltende Symptome (Frontiers in Pediatrics). Das Immunsystem von Kindern entwickelt keine "adaptiven" Erinnerungen, die vor einer erneuten SARS-CoV-2-Infektion schützen (Garvan Institute of Medical Research). Die Prävalenz von Langzeitfolgen bei COVID-19 liegt bei 23,36% (ScienceDirect). Die Omikron-Variante verursacht siebenmal mehr Todesfälle bei hospitalisierten Kindern als die Influenza (South China Morning Post). In Ohio haben zwischen 30.000 und 70.000 Kinder Long COVID (US News). COVID-19 kann zu Herzerkrankungen bei Kindern führen (MDPI Open Access Journals). Entzündliche Erkrankungen bei Kindern nach COVID-19 (ScienceDirect). Neurologische Komplikationen nach COVID-19 bei Kindern (American Academy of Pediatrics). Augenmanifestationen von COVID-19 bei Kindern (SageJournals). Beeinträchtigungen der Gesundheit bei Kindern und Jugendlichen nach einer COVID-19-Erkrankung (American Academy of Pediatrics). Nahezu alle mit COVID-19 infizierten Kinder zeigen Anzeichen von Schädigung der Blutgefäße (Blood Advances). Eine Studie zeigt, dass vorherige COVID-19-Infektionen mit einem signifikant erhöhten Risiko für RSV-Infektionen bei Kindern in Verbindung gebracht werden (medRxiv). Zwischen 12 und 16% der Kinder und Jugendlichen, die mit Omikron infiziert waren, erfüllen die Definition von Long COVID (Journal of Pediatrics). Diabetes-Typ-1-Inzidenz und -Risiko bei Kindern mit einer COVID-19-Diagnose (Jama Network). Prävalenz von Long COVID bei Kindern und Jugendlichen beträgt 25,24%, am häufigsten mit Stimmungssymptomen (Nature). Ungewöhnlicher Anstieg von Hirnabszessen bei amerikanischen Kindern (CDC). Veränderte Verformung der roten Blutkörperchen bei Kindern und Jugendlichen nach SARS-CoV-2-Infektion (Nature). Kinder haben ein ähnliches Risiko für Langzeitfolgen von Long COVID bei einer erneuten Infektion wie bei der Erstinfektion (Journal of Pediatrics). SARS-CoV-2 kann sich über Wochen bis Monate systemisch ausbreiten und persistieren, unabhängig von der Schwere der Erkrankung (Lancet).

Background Internal tremors and vibrations symptoms have been described as part of neurologic disorders but have not been fully described as a part of long COVID. We compared demographics, socioeconomic characteristics, pre-pandemic comorbidities, and new-onset conditions between people with internal tremors and vibrations as part of their long COVID symptoms and people with long COVID but without these symptoms. Methods A cross-sectional study, Listen to Immune, Symptom and Treatment Experiences Now (LISTEN), collected data from adults with long COVID. The study sample included 423 participants enrolled between May 2022 and June 2023. Results The 423 participants had a median age of 46 years (interquartile range, 38-56), 74% were female, 87% were Non-Hispanic White, and 158 (37%) reported “internal tremors, or buzzing/vibration” as a long COVID symptom. Before long COVID, the groups had similar comorbidities. Post-COVID, participants with internal tremors and vibrations had significantly worse health as measured by the Euro-QoL visual analogue scale (median: 40 vs. 50 points, P = 0.007), higher rates of financial difficulties caused by the pandemic and housing insecurity (P 0.001 for each), and were significantly more likely to have new-onset conditions of mast cell disorders (11% vs. 2.6%), neurologic conditions (22% vs. 8.3%), anxiety (20% vs. 8.7%), and trauma- or stress-related mental health disorders (12% vs. 3.4%) compared with those without internal tremors (Bonferroni-adjusted P 0.05 for each). Participants with internal tremors also reported significantly higher rates of cardiovascular, gastrointestinal, integumentary, and neurologic long COVID symptoms compared with those without internal tremors (Bonferroni- adjusted P 0.05 for each). Conclusions and Relevance Among people with long COVID, those with internal tremors and vibrations have more associated symptoms and worse health status, suggesting it may be associated with a severe phenotype of the condition. ### Competing Interest Statement Harlan Krumholz and his spouse are co-founders of, and have equity in, Hugo Health, the personalized health data-platform company that developed the Hugo Kindred platform.

Der Begriff Long-COVID ist ein Überbegriff, um die gesamte Krankheitslast zu beschreiben, die sich aus einer Infektion mit SARS-CoV-2 bei einem Individuum ergeben kann, die persönliche Krankheitslast, die enorm eingeschränkte Lebensqualität und die sozioökonomischen Auswirkungen auf Bevölkerungsebene, um daraus sinnvolle Präventionsmaßnahmen abzuleiten. Aus praktischer, diagnostischer, therapeutischer und wissenschaftlicher Sicht ist es jedoch wichtig zu differenzieren. Einerseits können verschiedene Krankheitsmechanismen zu Grunde liegen wie z.B.: Persistierendes Virusreservoir, latente Virusreaktivierung, Mikrobiom-Dysbiose, Erschöpfung von Immunzelluntergruppen und Autoimmunität, die zu latenten Entzündungsreaktionen, Gewebedysfunktion, hyperkoagulativem Status, Gefäßschäden, erhöhter Anfälligkeit für andere Infektionen, hormonellem Ungleichgewicht, Neuroinflammation und mitochondrialer Dysfunktion führen können.

Climate model estimates show significant groundwater depletion during the 20th century, consistent with global mean sea level (GMSL) budget analysis. However, prior to the Argo float era, in the early 2000’s, there is little information about steric sea level contributions to GMSL, making the role of groundwater depletion in this period less certain. We show that a useful constraint is found in observed polar motion (PM). In the period 1993–2010, we find that predicted PM excitation trends estimated from various sources of surface mass loads and the estimated glacial isostatic adjustment agree very well with the observed. Among many contributors to the PM excitation trend, groundwater storage changes are estimated to be the second largest (4.36 cm/yr) toward 64.16°E. Neglecting groundwater effects, the predicted trend differs significantly from the observed. PM observations may also provide a tool for studying historical continental scale water storage variations.
