The role of colchicine in the management of COVID-19: a Meta-analysis.

Background: The Coronavirus disease 2019 (COVID-19) pandemic has robustly affected the global healthcare and economic systems and it was caused by coronavirus-2 (SARS-CoV-2). The clinical presentation of the disease ranges from a flu-like illness to severe pneumonia and death. Till September 2022, the cumulative number of cases exceeded 600 million worldwide and deaths were more than 6 million.

Evaluation of klotho expression on peripheral blood lymphocytes among hemodialysis patients and its possible contribution to their immuno-compromised status.

Infection is the second most common cause of mortality among end-stage kidney disease (ESKD) patients. Uremic toxins are the main cause of impaired immune response among ESKD patients. Klotho gene, the anti-aging gene, encodes the transmembrane alpha klotho (αKL) protein which acts as an obligate coreceptor for fibroblast growth factor 23 (FGF23).

Effect of different types of supervised exercise programs on cardiorespiratory and muscular fitness, pain, fatigue, mental health and inflammatory and oxidative stress biomarkers in older patients with post-COVID-19 sequelae "EJerSA-COVID-19": a randomized controlled trial.

Background: Many patients with COVID-19 present the so-called post-acute sequelae of COVID-19 such as fatigue, post-stress discomfort, dyspnea, headache, pain mental impairment, incapacity to perform daily physical tasks ant exercise intolerance. This study aims to investigate the effects of different exercise programs on physical and mental fitness, physical condition and biomarkers of the immune system and oxidative stress in older patients with post-COVID-19 sequelae.

Methods: The sample will be made up of 120 eligible participants, over the age of 60 years who have had COVID-19 disease and are survivors and present persistent COVID-19 symptomatology diagnosed by the corresponding physician.

Exploring the recovery of potassium-rich struvite after a nitrification-denitrification process in pig slurry treatment.

The integration of biological nitrogen (N) removal with struvite-type material recovery, which contained phosphorus (P) and potassium (K), was proved to be technically feasible in pig slurry treatment. Phosphate (PO) salts were precipitated by raising the pH-value, using denitrified effluent and waste sludge purged from the bioreactor. When P was limiting, the unbalanced composition of the denitrified effluent resulted in low K-removal efficiency from the liquid phase; 10 % maximum when the initial pH-value was adjusted to 11.

Neutrophil Respiratory Burst: an immunological indicator of post stroke infection.

Stroke is long known to be followed by a series of immunosuppressive events, and infections might be a cause of death after an acute insult of stroke. The aim of our work was to assess the percentage of neutrophils showing spontaneous oxidative burst in patients with acute ischemic stroke. The study included 30 patients with acute cerebral infarction subjected to the following: magnetic resonance imaging of the brain immediately on admission, and blood sampling on day one of admission (baseline) and after 3 days of admission.
