Toxicity as prime selection criterion among SARS-active herbal medications
2021
We present here a new selection criterion for prioritizing research on efficacious drugs for the fight against COVID-19: the relative toxicity versus safety of herbal medications, which were effective against SARS in the 2002/2003 epidemic. We rank these medicines according to their toxicity versus safety as basis for preferential rapid research on their potential in the treatment of COVID-19. The data demonstrate that from toxicological information nothing speaks against immediate investigation on, followed by rapid implementation of Lonicera japonica, Morus alba, Forsythia suspensa, and Codonopsis spec. for treatment of COVID-19 patients. Glycyrrhiza spec. and Panax ginseng are ranked in …
Visceral adiposity index and metabolic profile in adult patients with congenital adrenal hyperplasia: hydrocortisone versus prednisone treatment.
2013
Background: Patients with Congenital Adrenal Hypeplasia (CAH) due to 21-hydroxylase deficiency need a life-long therapy with glucocorticoids (GCs) and tend to have a cluster of metabolic risk factors, which are consistent with metabolic syndrome (MS). Most frequently used GCs are Hydrocortisone (HC) and Prednisone (P), different for both pharmacodynamic and pharmacokynetic characteristics. Aim: The aim of this study was to evaluate the impact of HC and P on VAI, a new indicator of visceral fat function, and on metabolic profile in CAH patients long term treated with GC. Materials and Methods: Thirty-two patients (22 F, 10 M, 18-46 yrs), among which 16 (11 F, 5 M) treated with HC (dose 10-45…
Impact of smoking on COVID-19 outcomes: a HOPE Registry subanalysis
2021
BackgroundSmoking has been associated with poorer outcomes in relation to COVID-19. Smokers have higher risk of mortality and have a more severe clinical course. There is paucity of data available on this issue, and a definitive link between smoking and COVID-19 prognosis has yet to be established.MethodsWe included 5224 patients with COVID-19 with an available smoking history in a multicentre international registry Health Outcome Predictive Evaluation for COVID-19 (NCT04334291). Patients were included following an in-hospital admission with a COVID-19 diagnosis. We analysed the outcomes of patients with a current or prior history of smoking compared with the non-smoking group. The primary …
The Role of Vitamin D as a Biomarker in Alzheimer’s Disease
2021
Vitamin D and cognition is a popular association, which led to a remarkable body of literature data in the past 50 years. The brain can synthesize, catabolize, and receive Vitamin D, which has been proved to regulate many cellular processes in neurons and microglia. Vitamin D helps synaptic plasticity and neurotransmission in dopaminergic neural circuits and exerts anti-inflammatory and neuroprotective activities within the brain by reducing the synthesis of pro-inflammatory cytokines and the oxidative stress load. Further, Vitamin D action in the brain has been related to the clearance of amyloid plaques, which represent a feature of Alzheimer Disease (AD), by the immune cell. Based on the…
Post-Transcriptional Regulation of Iron Homeostasis in Saccharomyces cerevisiae
2013
Iron is an essential micronutrient for all eukaryotic organisms because it participates as a redox cofactor in a wide variety of biological processes. Recent studies in Saccharomyces cerevisiae have shown that in response to iron deficiency, an RNA-binding protein denoted Cth2 coordinates a global metabolic rearrangement that aims to optimize iron utilization. The Cth2 protein contains two Cx8Cx5Cx3H tandem zinc fingers (TZFs) that specifically bind to adenosine/uridine-rich elements within the 3' untranslated region of many mRNAs to promote their degradation. The Cth2 protein shuttles between the nucleus and the cytoplasm. Once inside the nucleus, Cth2 binds target mRNAs and stimulate…

Do ventilatory parameters influence outcome in patients with severe acute respiratory infection? Secondary analysis of an international, multicentre1…
2021
Purpose: To investigate the possible association between ventilatory settings on the first day of invasive mechanical ventilation (IMV) and mortality in patients admitted to the intensive care unit (ICU) with severe acute respiratory infection (SARI). Materials and methods: In this pre-planned sub-study of a prospective, multicentre observational study, 441 patients with SARI who received controlled IMV during the ICU stay were included in the analysis. Results: ICU and hospital mortality rates were 23.1 and 28.1%, respectively. In multivariable analysis, tidal volume and respiratory rate on the first day of IMV were not associated with an increased risk of death; however, higher driving pr…
Biological Basis of the HLA-B8,DR3-Associated Progression of Acquired Immune Deficiency Syndrome
1998
The factors influencing the evolution of human immunodeficiency virus (HIV) infection are not fully known, but the host genotype undoubtedly plays a role in determining the outcome of the disease by affecting the immune response to HIV. The role of the host human leukocyte antigen (HLA) genotype in the regulation of susceptibility to HIV infection and expression has been studied extensively in different major risk groups. Certain HLA alleles and haplotypes, being associated with aberrant immune responses independently from HIV infection, have been reported to facilitate the rapid progression of disorders related to HIV infection. Particularly, the association of rapid acquired immunodeficie…
