One disease, many faces – typical and atypical presentations of SARS-CoV-2 infection-related COVID-19 disease

This study titled “One disease, many faces – typical and atypical presentations of SARS-CoV-2 infection-related COVID-19 disease” by Philips CA et al., published in the World Journal of Clinical Cases provides a comprehensive review focusing on the various clinical presentations of COVID-19, emphasizing the disease’s multisystem impact and the diverse symptoms beyond the commonly known respiratory manifestations. Abstract Summary: The review acknowledges that while COVID-19 is primarily known for respiratory symptoms, there is significant evidence of a wide range of clinical presentations. This review aims to provide an in-depth analysis of these varied presentations, which is crucial for frontline clinicians…

Persistent SARS-CoV-2 infection: significance and implications

The study “Persistent SARS-CoV-2 infection: significance and implications” delves into the complexities and challenges posed by prolonged SARS-CoV-2 infections, especially in immunocompromised individuals. These persistent infections represent a significant clinical and public health concern due to their potential role in the emergence of novel virus variants through ongoing viral replication and evolution. Key Points from the Study: Conclusions: The study underscores the urgent need for a concerted effort in research, clinical management, and public health strategies to address persistent SARS-CoV-2 infections. By improving our understanding of these infections, developing effective diagnostics and treatments, and implementing robust surveillance, we can mitigate…

Microstructural brain abnormalities, fatigue, and cognitive dysfunction after mild COVID-19

The study titled “Microstructural brain abnormalities, fatigue, and cognitive dysfunction after mild COVID-19” aimed to investigate cognitive dysfunction and brain changes in individuals who experienced mild SARS-CoV-2 infection. A total of 97 unvaccinated individuals, with a median age of 41 years, were examined approximately 79 days (median) after their COVID-19 diagnosis. The participants underwent semi-structured interviews, neurological examinations, 3T-MRI scans, and neuropsychological assessments. The study excluded individuals with current or a history of psychiatric symptoms, including anxiety and depression, to avoid biases related to brain changes and cognitive dysfunction associated with these conditions. Key Findings: Conclusions: The study suggests that…

A comprehensive SARS-CoV-2 and COVID-19 review, Part 2: host extracellular to systemic effects of SARS-CoV-2 infection

The study titled “A Comprehensive SARS-CoV-2 and COVID-19 Review” provides an extensive analysis of the various impacts of SARS-CoV-2 and its resulting diseases, COVID-19 and Post-Acute Sequelae of SARS-CoV-2 (PASC), also known as Long COVID-19. As of January 13, 2023, COVID-19 has led to over 671 million cases and more than 6.71 million deaths worldwide. The pandemic’s impact has been far-reaching, affecting multiple organ systems and leading to a variety of long-term health issues​​. Key Insights from the Study: In conclusion, the study underscores the complexity and dynamics of COVID-19, highlighting the intricate interplay between various biochemical pathways and organ…

Cognitive deficits in people who have recovered from COVID-19

The study titled “Cognitive deficits in people who have recovered from COVID-19” provides vital insights into the long-term cognitive effects observed in individuals who have recovered from COVID-19. This research is particularly relevant due to growing concerns about the cognitive consequences of COVID-19, especially in the context of ‘Long COVID’ symptoms persisting into the chronic phase​​. Key Findings of the Study: Implications: This study highlights the importance of considering cognitive deficits as part of the recovery process from COVID-19, especially for individuals who have been hospitalized. The findings underscore the need for further research to understand the full spectrum of…

Post-COVID cognitive deficits at one year are global and associated with elevated brain injury markers and grey matter volume reduction: national prospective study

The study, “Post-COVID cognitive deficits at one year are global and associated with elevated brain injury markers and grey matter volume reduction: national prospective study” provides crucial insights into the long-term cognitive impacts of COVID-19. Here is a detailed summary: Abstract and Background: This prospective national longitudinal study investigated cognitive deficits in 351 hospitalized COVID-19 patients compared to 2,927 matched controls. The research found global cognitive deficits associated with elevated brain injury markers and reduced grey matter volume in the anterior cingulate cortex one year post-hospital admission. The severity of the initial COVID-19 infection, psychiatric symptoms post-acute phase, and history…

A hypoarousal model of neurological post‑COVID syndrome

The study “A Hypoarousal Model of Neurological Post-COVID Syndrome:the relation between mental fatigue, the level of central nervousactivation and cognitive processing speed” investigates the relationship between cognitive dysfunction, mental fatigue, and hypoarousal of the brain in post-COVID patients. Here’s a detailed summary: Background and Objectives: Post-COVID syndrome often includes neurological and neuropsychiatric sequelae, particularly cognitive dysfunction and fatigue. This study hypothesized that these symptoms in post-COVID syndrome are linked to hypoarousal of the brain. It aimed to assess whether tonic alertness, a neurocognitive index of arousal, is reduced in post-COVID patients and how this relates to central nervous activation and…
