Post COVID-19 symptoms are common, also among young adults in the general population
Scientific Reports - Post COVID-19 symptoms are common, also among young adults in the general population
The most common post COVID-19 symptoms were altered smell and taste (68.8%), dyspnea (33.7%) and fatigue (30.4%). Overall, no major risk factors for post COVID-19 were identified except for being bedbound during COVID-19. However, asthma and rhinitis were associated with the post COVID-19 symptom dyspnea, migraine with altered smell and taste, and lower self-rated health with fatigue. In conclusion, post COVID-19 symptoms are common, also among young adults in the general population. Although not life-threatening, it could have a considerable impact on public health due to the high prevalence and long-term symptoms.

The protein expression profile of ACE2 in human tissues
The novel SARS-coronavirus 2 (SARS-CoV-2) poses a global challenge on healthcare and society. For understanding the susceptibility for SARS-CoV-2 infection, the cell type-specific expression of the host cell surface receptor is necessary. The key protein suggested to be involved in host cell entry is angiotensin I converting enzyme 2 (ACE2). Here, we report the expression pattern of ACE2 across 150 different cell types corresponding to all major human tissues and organs based on stringent immunohistochemical analysis. The results were compared with several datasets both on the mRNA and protein level. ACE2 expression was mainly observed in enterocytes, renal tubules, gallbladder, cardiomyocytes, male reproductive cells, placental trophoblasts, ductal cells, eye, and vasculature. In the respiratory system, the expression was limited, with no or only low expression in a subset of cells in a few individuals, observed by one antibody only. Our data constitute an important resource for further studies on SARS-CoV-2 host cell entry, in order to understand the biology of the disease and to aid in the development of effective treatments to the viral infection.
Syncytia formation by SARS-CoV-2-infected cells - PubMed
Severe cases of COVID-19 are associated with extensive lung damage and the presence of infected multinucleated syncytial pneumocytes. The viral and cellular mechanisms regulating the formation of these syncytia are not well understood. Here, we show that SARS-CoV-2-infected cells express the Spike p …
Increased risk of acute myocardial infarction after COVID-19 recovery: A systematic review and meta-analysis
To assess the incidence and risk of AMI in COVID-19 survivors after SARS-CoV-2 infection by a systematic review and meta-analysis of the available data.
Methods
Data were obtained searching MEDLINE and Scopus for all studies published at any time up to September 1, 2022 and reporting the risk of incident AMI in patients recovered from COVID-19 infection. AMI risk was evaluated using the Mantel–Haenszel random effects models with Hazard ratio (HR) as the effect measure with 95% confidence interval (CI) while heterogeneity was assessed using Higgins and Thomson I2 statistic.
Results
Among 2765 articles obtained by our search strategy, four studies fulfilled the inclusion criteria for a total of 20,875,843 patients (mean age 56.1 years, 59.1% males). Of them, 1,244,604 had COVID-19 infection. Over a mean follow-up of 8.5 months, among COVID-19 recovered patients AMI occurred in 3.5 cases per 1.000 individuals compared to 2.02 cases per 1.000 individuals in the control cohort, defined as those who did not experience COVID-19 infection in the same period). COVID-19 patients showed an increased risk of incident AMI (HR: 1.93, 95% CI: 1.65–2.26, p 0.0001, I2 = 83.5%). Meta-regression analysis demonstrated that the risk of AMI was directly associated with age (p = 0.01) and male gender (p = 0.001), while an indirect relationship was observed when the length of follow-up was utilized as moderator (p 0.001).
Conclusion
COVID-19 recovered patients had an increased risk of AMI.

Was SARS-CoV-2 dem Körper antut: Eine wachsende und unvollständige Übersicht
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).

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).

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).

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).

Internal tremors and vibrations in long COVID: a cross-sectional study
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.
