Post‑viral syndrome is a well‑known medical condition characterized by different levels of physical, cognitive, and emotional impairment that may persist with fluctuating severity after recovering from an acute viral infection. Unsurprisingly, COVID‑19 also be accompanied medium- long‑term clinical sequelae SARS‑CoV‑2 Although many definitions have been provided, "long‑COVID" can defined as occurring in patients history infection, developing 3 months the symptoms onset, persisting for at least 2 months, not explained alternative diagnoses. According to recent global analyses, cumulative prevalence long‑COVID seems range between 9% 63%, up 6‑fold higher than similar postviral infection conditions. Long‑COVID primarily encompasses presence 1 symptom, such fatigue, dyspnea, cognitive / brain fog, postexertional malaise, memory issues, musculoskeletal pain spasms, cough, sleep disturbances, tachycardia palpitations, altered smell taste perception, headache, chest pain, depression. The most important demographic predictors date are female sex, older age, cigarette smoking, pre‑existing conditions, lack vaccination, pre‑Omicron variants, number phase symptoms, load, severe critical illness, well invasive mechanical ventilation. Concerning care patients, greatest challenge fact this cannot considered single entity, thus it needs integrated multidisciplinary management, specifically tailored type symptoms.

Cardiac involvement has been noted in COVID-19 infection. However, the relationship between post-recovery and development of de novo heart failure not investigated a large, nationally representative population. We examined outcomes 587,330 patients hospitalized United States (257,075 with 330,255 without), using data from National COVID Cohort Collaborative study. Patients were older (51 vs. 46 years), more often male (49% 42%), less White (61% 69%). Over median follow up 367 days, 10,979 incident events occurred. After adjustments, hospitalization was associated 45% higher hazard (hazard ratio = 1.45; 95% confidence interval: 1.39-1.51), pronounced associations among who younger (P-interaction 0.003), 0.005), or had established cardiovascular disease 0.005). In conclusion, is increased risk failure.

Abstract It is well established that the risk of venous thromboembolism high in coronavirus disease 19 (COVID-19). The frequency arterial thromboembolic events (ATEs) hospitalized patients with COVID-19 unclear, as magnitude these comparison other infections. We searched MEDLINE from February 2020 to 2022 for prospective or retrospective cohort studies and randomized clinical trials reported number acute myocardial infarction (AMI), ischemic stroke (AIS), limb ischemia (ALI), ATE defined by original authors COVID-19. pooled frequencies were calculated through meta-analysis using random effects model logit transformation presented relative 95% prediction intervals (95% PI). retrieved a total 4,547 studies, 36 which (28 cohorts, five cohorts three trials) finally included our analysis. resulting counted 100,949 patients, 2,641 (2.6%) whom experienced ATE. was 2.0% PI, 0.4–9.6%).

SARS-CoV-2 Breakthrough Infections: Incidence and Risk Factors in a Large European Multicentric Cohort of Health Workers

Vaccines, Journal Year: 2022, Volume and Issue: 10(8), P. 1193 - 1193

Published: July 27, 2022

The research aimed to investigate the incidence of SARS-CoV-2 breakthrough infections and their determinants in a large European cohort more than 60,000 health workers.A multicentric retrospective study, involving 12 centers, was carried out within ORCHESTRA project, collecting data up 18 November 2021 on fully vaccinated workers. cumulative investigated with its association occupational social-demographic characteristics (age, sex, job title, previous infection, antibody titer levels, time from vaccination course completion).Among 64,172 workers 797 were observed (cumulative 1.2%). primary analysis using individual 8 centers showed that age infection significantly modified rates. In meta-analysis aggregated all standardized inversely related risk (p = 0.008 p 0.007, respectively).The inverse correlation supports evidence plays role prevention, especially Cellular immunity, clinical conditions, timing should be further investigated.

Antigenicity comparison of SARS‐CoV‐2 Omicron sublineages with other variants contained multiple mutations in RBD

MedComm, Journal Year: 2022, Volume and Issue: 3(2)

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants, particularly those with multiple mutations in receptor-binding domain (RBD), pose a critical challenge to the efficacy of disease 2019 (COVID-19) vaccines and therapeutic neutralizing monoclonal antibodies (mAbs). Omicron sublineages BA.1, BA.2, BA.3, as well recent emergence C.1.2, B.1.630, B.1.640.1, B.1.640.2, have RBD may lead antibody evasion. It is urgent evaluate antigenic change above seven variants against mAbs sera from guinea pigs immunized concern (VOCs) (Alpha, Beta, Gamma, Delta, Omicron) interest (VOIs) (Lambda, Mu) immunogens. Only out 24 showed no reduction activity BA.3. However, among these mAbs, neutralization XGv337 XGv338 B.1.640.2 were decreased. Therefore, only five significant variants. Using VOCs VOIs immunogens, we found that antigenicity could be divided into three clusters, each cluster similar different Among them, D614G, B.1.630 formed cluster, C.1.2 BA.3 cluster.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant of concern (VoC) Omicron (B.1.1.529) has rapidly spread around the world, presenting a new threat to global public human health. Due large number mutations accumulated by SARS-CoV-2 Omicron, concerns have emerged over potentially reduced diagnostic accuracy reverse-transcription polymerase chain reaction (RT-qPCR), gold standard test for diagnosing disease 2019 (COVID-19). Thus, we aimed assess impact currently endemic sublineages BA.4 and BA.5 on integrity sensitivity RT-qPCR assays used (COVID-19) diagnosis via in silico analysis.

The SARS-CoV-2 infection is characterized by both systemic and organ hyper-thromboinflammation, with a clinical course ranging from mild up-to critical dysfunction death. In patients coronavirus disease 2019 (COVID-19) the monocyte/macrophage population deeply involved as trigger target, assuming value of useful diagnostic/prognostic marker innate cellular immunity. Several studies correlated morphological immunophenotypic alterations circulating monocytes outcomes in COVID-19 patients, concluding that monocyte distribution width (MDW) may retain stratifying risk worsening. Through an electronic search Medline Scopus we performed updated literature review meta-analysis aimed to explore association between increased MDW levels illness severity deciphering role(s) function(s) harmful network underlining infection. We found significantly elevated values were frequently present who developed unfavorable outcomes, compounded significant anisocytosis outcomes. These findings suggest blood index its scatter plot could represent routine laboratory tools for early identification at higher monitoring progression viral infection, therapeutic efficacy throughout hospitalization. According this evidence, decisions benefit value, administration drugs limiting thrombo-inflammation due hyper-activation severe/critical disease.
