Interesting study with 1301 patients, employees of one of the biggest national banks in Turkey. idcmjournal.org/long-covid
2) The study examined the prevalence and risk factors for long COVID, defined as persisting symptoms for 3 or more months after acute COVID-19 infection.
A total of 1301 patients were surveyed who had tested positive for COVID-19 between March 2020 to September 2021.
3) All were employees of a large Turkish bank.
19.8% of patients (257 individuals) met the criteria for long COVID, having at least one symptom persisting for 3 or more months.
The most commonly reported long-term symptoms were myalgia (14.3%), arthralgia (14.1%) ...
4) ...and back pain (13.8%). Musculoskeletal and neurological systems were most frequently affected.
Female gender and diabetes mellitus were identified as independent risk factors for long COVID based on multivariate regression analysis.
5) COVID-19 severity did not have a significant association with long COVID risk, suggesting long-term impacts beyond acute disease severity.
The study helps characterize the prevalence and risk factors for long COVID in Turkey.
6) Identifying those at higher risk may aid in management and rehabilitation efforts.

WHY INFECTIONS by BACTERIA, VIRUSES and FUNGI will INCREASE in the FUTURE ? ๐งต
2 recent studies highlights important concerns about the rise of infections caused by bacteria, viruses, fungi and the role of COVID-19
2) One study focuses on antibiotic resistance, where bacteria become resistant to medicines meant to kill them. This often happens due to the overuse of antibiotics in healthcare and agriculture, along with a lack of new antibiotics being developed.
3) As these bacteria evolve and become harder to treat, even common infections could lead to severe health problems.
The second study discusses how climate change and urban growth are contributing to the increase in viral and fungal infections.
2) Astrocytes are the brain cells that can be infected and support the growth of the SARS-CoV-2 virus. This likely contributes to the neurological symptoms of COVID-19.
3) Experiments show ketamine, an anesthetic, can reduce astrocyte infection by earlier SARS-CoV-2 variants, but not newer variants. Ketamine does this by decreasing the virus's entry receptor and replication in astrocytes.
2) This first figure helps explain the first key mechanisms contributing to cognitive impairment in COVID-19 patients:
โถ๏ธ Direct viral entry and brain injury is shown in the first panel.
โถ๏ธ The role of hypoxia (lack of oxygen) in cognitive decline is depicted in the second panel
3) โถ๏ธ The widespread systemic inflammation caused by COVID-19 is illustrated in the third panel.
For CHILDREN, the risk of LONG COVID after a SECOND INFECTION is 2.08 TIMES GREATER compared to the FIRST INFECTION. medrxiv.org/content/10.110โฆ
2) Let's summarize first this study :
The researchers used medical records from 40 children's hospitals in the US between January 2022 and October 2023. They compared the risk of long-term issues in those with a second COVID-19 infection versus their first infection.
3) Results showed that children with a 2nd infection had a significantly higher risk of various long-term problems, including:
- Heart issues like inflammation and abnormal heart rhythms
- Changes in taste and smell
- Blood clots
- Kidney problems
- Fatigue and muscle/joint pain
What a "CLEVER" SARS-COV-2 virus !
... which induced a P812S mutation in a chronically ill individual, that is somewhat less pathogenic but enables the virus to infect a larger population. biorxiv.org/content/10.110โฆ
2) This study looks at how a single mutation, called P812S, in the SARS-CoV-2 virus can have different effects. The P812S mutation was found in a person with a long-term COVID-19 infection.
3) The study found that the P812S mutation:
- Reduced the ability of the virus to enter cells and cause them to fuse together (form syncytia). This is linked to less severe COVID-19 disease.
- Helped the virus evade antibodies that target the fusion peptide region of the spike.
INSIDE a COVID-19 crashing WAVE (Nov. 2023 and Mar. 2024, coastal Kenya) ๐
Fascinating information on variants, symptoms, reinfections, ...

2) The study examines the genomic and clinical epidemiology of a SARS-CoV-2 wave that occurred in coastal Kenya between November 2023 and March 2024. Key findings include:
- The wave was dominated by the XBB.2.3-like and JN.1-like Omicron subvariants ...
3) ... which were introduced through multiple independent events, primarily from North America and Europe.
- Genomic surveillance revealed at least 38 separate virus introduction events into the local population during this wave.
