Also ich habe auch Mini-Aspirin in der kleinstmöglichen Dosis rumliegen (75 mg). Davon würde ich dauerhaft höchstens eine halbe nehmen, falls mir nicht anderes zur Verfügung stünde.

Trotzdem bin ich ein Gegner regelmäßiger Aspirineinnahme.

Im Prinzip kann m.Mng. nach Aspirin nichts, was andere nicht besser können. Vitamin K, Magnesium, Piracetam, Curcuma, das alles sind bessere Mittel für die verschiedenen Beschwerden. Diese haben auch weniger Nebenwirkungen. Warum also sollte ich Aspirin einnehmen, wenn es bessere Substanzen mit weniger Nebenwirkungen gibt.

Aspirin fördert die Schwerhörigkeit. Magnesium und Piracetam verhindern sie nicht nur, sondern verbessern sogar teilweise das Hörvermögen.

Vitamin K verbessert nicht nur Blutgefäße, sondern auch die Zähne und die Knochen...

Curcuma hemmt COX-2 (Entzündungen), ohne den Magen kaputtzumachen.

Wir haben einfach bessere Alternativen als Aspirin und brauchen das gar nicht bzw. höchstens als Notfallmedikament.

Zitat von Wolfgang aus Berlin im Beitrag #59
Zitat: "For the aspirin-exposed patient population, the study included only patients who had at least one year of once-daily aspirin exposure at a dose of 81 or 325 mg ccurring between January 2005 and December 2006 in order to allow for at least five years of follow-up data to detect if melanoma occurred over time."

Irgend einen Link einzustellen ohne Interpretation, ist nicht gut. Das verwirrt nur.

Wenn die Autoren zwei unterschiedliche Dosierungen in einen Topf schmeißen, ist die Studie nicht brauchbar. Die positiven Effekte wurden bisher für Dosierungen zwischen 81 und 100 mg ermittelt und gerade nicht für höhere Dosierungen.
Ich kenne die Studie nicht im Einzelnen. Oder gibt es noch andere Erkenntnisse?



Die Original-Studie wird unten im Bericht genannt. Es gibt aber keinen freien Zugang dazu.

Aspirin hilft bei Alzheimer
Plaques lösen sich auf
Eine Kur mit niedrig dosiertem Aspirin löst möglicherweise Plaques im Gehirn auf, die die Alzheimer-Krankheit auslösen. Das ist das Ergebnis der Studie eines Teams um die Neurologen Professor Floyd A. Davis und Kalipada Pahan vom Rush University Medical Center http://rushu.rush.edu . "Die Ergebnisse unserer Studie zeigen, dass eines der meist genutzten rezeptfreien Medikamente eine weitere Rolle spielen könnte", sagt Pahan.

Zitat
Kleinere Plaques nach einem Monat Die Forscher konnten bei Versuchen an Mäusen zeigen, dass Aspirin Lysosome aktivieren, die Biopolymere in Monomere zerlegen. Diese bilden sich aus dem Protein TFEB. Sie sind für die "Reinigung" des Gehirns zuständig. Die an Alzheimer künstlich erkrankten Mäuse erhielten einen Monat lang Aspirin. Danach hatten sich die Plaques deutlich verkleinert.

Low-Dose Aspirin Upregulates Tyrosine Hydroxylase and Increases Dopamine Production in Dopaminergic Neurons: Implications for Parkinson's Disease.

Increasing the function of residual dopaminergic neurons in the nigra of PD patients is an important area of research as it may eventually compensate the loss. Although tyrosine hydroxylase (TH) is the rate-limiting enzyme in the dopamine (DA) biosynthesis pathway, there are no effective drugs/molecules to upregulate TH and increase the production of DA in nigral dopaminergic neurons. This study underlines the importance of aspirin in stimulating the expression of TH and increasing the level of DA in dopaminergic neurons. At low doses, aspirin increased the expression of TH and the production of DA in mouse MN9D dopaminergic neuronal cells. Accordingly, oral administration of aspirin increased the expression of TH in the nigra and upregulated the level of DA in striatum of normal C57/BL6 mice and aged A53T α-syn transgenic mice. Oral aspirin also improved locomotor activities of normal mice and A53T transgenic mice. While investigating mechanisms, we found the presence of cAMP response element (CRE) in the promoter of TH gene and the rapid induction of cAMP response element binding (CREB) activation by aspirin in dopaminergic neuronal cells. Aspirin treatment also increased the level of phospho-CREB in the nigra of C57/BL6 mice. The abrogation of aspirin-induced expression of TH by siRNA knockdown of CREB and the recruitment of CREB to the TH gene promoter by aspirin suggest that aspirin stimulates the transcription of TH in dopaminergic neurons via CREB. These results highlight a new property of aspirin in stimulating the TH-DA pathway, which may be beneficial in PD patients. Graphical Abstract ᅟ.

Aspirin in geringen Dosen scheint scheint MS-Symptome zu lindern, Schübe zu verhindern und evtl. sogar die Degeneration "zurückzuschrauben"

Aspirin ameliorates experimental autoimmune encephalomyelitis through interleukin-11–mediated protection of regulatory T cells

"...We observed marked expression of proinflammatory molecules like iNOS and IL-1 in spinal cord tissue from untreated RR-EAE mice when compared to control mice (fig. S1A and Fig. 2, D and E). However, aspirin treatment markedly suppressed the mRNA expression of iNOS and IL-1 in spinal cord tissue from mice with RR-EAE (fig. S1A and Fig. 2, D and E)."

"...Additionally, recombinant human IL-11 markedly suppresses bacterial lipopolysaccharide-induced NO production from macrophages (35). Therefore, it is possible that IL-11 prevented conversion of Tregs in EAE mice by suppressing the production of NO."

"...Here, we describe a new function of aspirin in which this drug inhibits the autoimmune disease EAE. Oral use of low-dose aspirin reduced the progression of both adoptively transferred and chronic EAE in mice. Aspirin treatment of mice with EAE also inhibited the invasion of mononuclear cells into the spinal cord as well as the expression of inflammatory molecules [inducible nitric oxide synthase (iNOS) and IL-1] and restored myelination and the expression of myelin-specific genes within the CNS. A recent double-blind randomized controlled pilot trial suggests that aspirin may represent an effective pretreatment for exercise in MS (29). Fatigue is very common in MS, and low-dose aspirin is also being considered for treating MS-related fatigues (30). Here, our preclinical data suggest that low-dose aspirin may be repurposed for disease modification in MS patients.

"...Although at high doses aspirin is reported to exhibit some toxic effects (gastric ulcers, stomach bleeding, tinnitus, etc.) (38), in our study aspirin suppressed the disease process of EAE at low doses (1 and 2 mg/kg body weight per day). A single pill of baby aspirin containing 81 mg of aspirin is considered to be very much safe for adults for daily use, and the doses we used in mice are almost equivalent to baby aspirin."

Lose-dose aspirin may help fight MS, study with mice says
"...Although the findings are so far only in mice, studies suggest that aspirin -- even the "low-dose" variety -- might help counter multiple sclerosis. Multiple sclerosis, or MS, is an autoimmune disorder where aberrant immune system T-cells attack and destroy the protective myelin protein sheath that coats nerves."

"...For the study, Mondal's team fed aspirin to mice specially bred to mimic the human form of MS. The investigators found that even low doses of aspirin -- equal to the 81 milligram "baby aspirin" many take to ward off heart trouble -- seemed to curb symptoms of MS in the mice. What's more, the pain reliever seemed to push back the underlying disease itself. "

"..."Although mouse results are not always translated to humans, our results highlight an undiscovered property of aspirin and suggest that low-dose aspirin may be repurposed for therapeutic intervention in MS," the study team wrote."

Researchers conducted a database search to investigate whether aspirin can aid in the prevention of intracranial aneurysm rupture by hindering aneurysm growth. The researchers identified 146 patients harboring multiple intracranial aneurysms, five millimeters or less in diameter, that had been observed for at least five years. In this set of patients, the researchers found an association between aspirin use and a decreased rate of aneurysm growth. Growth is important in intracranial aneurysms because it increases the risk of aneurysm rupture. Detailed findings are found in the article, "Aspirin associated with decreased rate of intracranial aneurysm growth," by Mario Zanaty, M.D., and colleagues, published today in the Journal of Neurosurgery.


https://thejns.org/view/journals/j-neuro...6.JNS191273.xml


RESULTS

The authors identified 146 patients harboring a total of 375 IAs. At the initial encounter, 146 aneurysms were treated and the remaining 229 aneurysms (2–5 mm) were observed. During the follow-up period, 24 (10.48%) of 229 aneurysms grew. All aneurysms observed to grow later underwent treatment. None of the observed aneurysms ruptured. Multivariate analysis showed that aspirin was significantly associated with a decreased rate of growth (odds ratio [OR] 0.19, 95% confidence interval [CI] 0.05–0.63). Variables associated with an increased rate of growth included hypertension (OR 14.38, 95% CI 3.83–53.94), drug abuse (OR 11.26, 95% CI 1.21–104.65), history of polycystic kidney disease (OR 9.48, 95% CI 1.51–59.35), and subarachnoid hemorrhage at presentation (OR 5.91, 95% CI 1.83–19.09).

CONCLUSIONS

In patients with multiple IAs, aspirin significantly decreased the rate of aneurysm growth over time. Additional prospective interventional studies are needed to validate these findings.

Hospitalized COVID-19 patients who were taking a daily low-dose aspirin to protect against cardiovascular disease had a significantly lower risk of complications and death compared to those who were not taking aspirin, according to a new study led by researchers at the University of Maryland School of Medicine (UMSOM).
Aspirin takers were less likely to be placed in the intensive care unit (ICU) or hooked up to a mechanical ventilator, and they were more likely to survive the infection compared to hospitalized patients who were not taking aspirin, The study, published today in the journal Anesthesia and Analgesia, provides "cautious optimism," the researchers say, for an inexpensive, accessible medication with a well-known safety profile that could help prevent severe complications.

"This is a critical finding that needs to be confirmed through a randomized clinical trial," said study leader Jonathan Chow, MD, Assistant Professor of Anesthesiology at UMSOM. "If our finding is confirmed, it would make aspirin the first widely available, over-the-counter medication to reduce mortality in COVID-19 patients."

To conduct the study, Dr. Chow and his colleagues culled through the medical records of 412 COVID-19 patients, age of 55 on average, who were hospitalized over the past few months due to complications of their infection. They were treated at the University of Maryland Medical Center in Baltimore and three other hospitals along the East Coast. About a quarter of the patients were taking a daily low-dose aspirin (usually 81 milligrams) before they were admitted or right after admission to manage their cardiovascular disease.

The researchers found aspirin use was associated with a 44 percent reduction in the risk of being put on a mechanical ventilator, a 43 percent decrease in the risk of ICU admission and -- most importantly -- a 47 percent decrease in the risk of dying in the hospital compared to those who were not taking aspirin. The patients in the aspirin group did not experience a significant increase in adverse events such as major bleeding while hospitalized.

Aspirin—another caloric-restriction mimetic


The capacity of cells and organisms to sustain, and to eventually adapt to, environmental and genetic insults declines with age. Because macroautophagy/autophagy is regarded as one of the major determinants of cellular fitness in vitro and in vivo, maneuvers that aim at promoting autophagy may slow down aging and promote health span. Caloric restriction (CR), a reduction in caloric intake without malnutrition, efficiently counteracts aging-associated features, yet is difficult to be applied to humans. Caloric-restriction mimetics (CRMs) are pharmacological agents that recapitulate the main biochemical properties of CR, namely a global reduction of protein acetylation and the induction of autophagy. We found that the ancient drug aspirin and its active metabolite salicylate stimulate autophagic flux by virtue of their inhibitory action on acetyltransferase EP300. The inhibition of EP300 results from a direct competition between salicylate and acetyl coenzyme A for binding to the catalytic domain of the enzyme. This mode of action appears to be conserved across evolution as it accounts for the induction of autophagy by aspirin in various mouse models and in the nematode Caenorhabditis elegans. In sum, aspirin acts as a CRM.
