Recent Longevity News for the week ending 4/13/22

Psilocybin rewires the brain for people with depression, study finds - Science Daily, 4/11/22 - "Scientists analyzed fMRI brain scans from nearly 60 people who had participated in two psilocybin trials. In the first one, all the participants had treatment-resistant depression and knew they were being given psilocybin. In the second one, the participants were depressed but not as severely, and they were not told whether they had been given psilocybin or a placebo that turned out to be escitalopram, an SSRI antidepressant. In addition to the drugs, all the participants received the same type of psychotherapy ... The scans, which were done before and after treatment, showed the psilocybin treatment reduced connections within brain areas that are tightly connected in depression, including the default mode, salience, and executive networks, and increased connections to other regions of the brain that had not been well integrated ... Participants were also less emotionally avoidant and their cognitive functioning got better. The improvement in their depressive symptoms correlated with changes to their brains, and these changes lasted until the study ended three weeks after the second psilocybin dose. No such changes were seen in the brains of those who received escitalopram, suggesting that psilocybin acts differently on the brain than SSRIs"

Research helps provide scientific framework for psilocybin use in therapeutic settings - Science Daily, 4/11/22 - "There are currently more than 60 psilocybin clinical trials overseen by the National Institutes of Health. Preliminary data suggest psilocybin therapies are effective in treating major depressive disorder, obsessive-compulsive disorder, smoking cessation and alcoholism ... Results of psilocybin ingestion outside of clinical trials have found an increased connection to nature, enhanced creativity, greater enjoyment of music and increased positive mood"

  • Oregon legalizes magic mushrooms: 5 things to know  - Oregon Online, 11/4/20 - "Psilocybin won’t be available to purchase and take home. Only license holders will be able to cultivate psilocybin or provide the therapy or own a psilocybin service center under the new law ... And it does not allow people to take or grow psychedelic mushrooms in their homes, or leave a treatment facility while still under the influence of psilocybin."

Ivermectin Does Not Improve COVID-19 Outcomes - Medscape, 4/11/22 - "Ivermectin is no more effective than placebo in reducing the severity of COVID-19 among newly diagnosed patients, according to the largest trial to date that has investigated this question ... Treatment with ivermectin failed to reduce hospital admissions for worsening COVID-19 and failed to shorten the time that patients with COVID-19 stayed as outpatients in the emergency room for observation ... The reasons for this include a minimal theoretical basis for concluding that benefits would outweigh potential harms, a track record of unreliable and downright fraudulent data supporting ivermectin, and the strong relationship between the quality of the clinical trial and finding of no benefit from ivermectin"

Old skins cells reprogrammed to regain youthful function - Science Daily, 4/8/22 - "Fibroblasts produce collagen, a molecule found in bones, skin tendons and ligaments, helping provide structure to tissues and heal wounds. The rejuvenated fibroblasts produced more collagen proteins compared to control cells that did not undergo the reprogramming process. Fibroblasts also move into areas that need repairing. Researchers tested the partially rejuvenated cells by creating an artificial cut in a layer of cells in a dish. They found that their treated fibroblasts moved into the gap faster than older cells. This is a promising sign that one day this research could eventually be used to create cells that are better at healing wounds"

Not all dietary fiber is created equal: cereal fiber but not fruit or vegetable fibers are linked with lower inflammation - Science Daily, 4/6/22 - "we are now learning that one particular type of dietary fiber -- cereal fiber -- but not fruit or vegetable fiber was associated with lower inflammation ... why cereal fiber but not vegetable or fruit fiber is associated with lower inflammation is not clear and warrants further investigation ... it is not clear whether cereal fiber per se or other nutrients in foods rich in cereal fiber are driving the observed relationships ... inflammation had only a modest role in mediating the observed inverse association between cereal fiber and CVD ... This suggests that factors other than inflammation may play a larger role in the cereal fiber-associated reduction in CVD and will need to be tested in future interventions of specific populations"

Low-Sodium Diet Did Not Cut Clinical Events in Heart Failure Trial - Medscape, 4/2/22 - "a greater reduction in sodium than achieved in this study or a longer follow-up may be required to show an effect on clinical events ... By 12 months, events comprising the primary outcome (hospitalization or emergency department visits due to cardiovascular causes or all-cause death) had occurred in 15% of patients in the low-sodium diet group and 17% of those in the usual care group (hazard ratio [HR], 0.89 ... All-cause death occurred in 6% of patients in the low-sodium diet group and 4% of those in the usual care group (HR, 1.38 ... All-cause death occurred in 6% of patients in the low-sodium diet group and 4% of those in the usual care group (HR, 1.38; P = .32). Cardiovascular-related hospitalization occurred in 10% of the low-sodium group and 12% of the usual care group (HR, 0.82; P = .36), and cardiovascular-related emergency department visits occurred in 4% of both groups (HR, 1.21 ... Quality-of-life measures on the Kansas City Cardiomyopathy Questionnaire (KCCQ) suggested a benefit in the low-sodium group, with mean between-group differences in the change from baseline to 12 months of 3.38 points in the overall summary score, 3.29 points in the clinical summary score, and 3.77 points in the physical limitation score (all differences were statistically significant)"

New PPI Data Again Link Medication Use to Alzheimer's - Medscape, 4/1/22 - "The odds of developing Alzheimer's disease were significantly higher in current (odds ratio [OR], 1.36; P < .001) and past (OR, 1.11; P < .001) PPI groups than in the control group ... Participants with PPI prescriptions for fewer than 30 days (OR, 1.13; P < .001), 30 to 90 days (OR, 1.18; P < .001), or more than 90 days (OR, 1.26; P < .001) all had higher odds of developing Alzheimer's disease than those in control group. An increased association between the cumulative duration of PPI exposure and the development of Alzheimer's disease was also observed. The odds of developing Alzheimer's disease were higher for users with more than 30 days of exposure than for those with fewer than 30 days"

Antibiotic Use in Midlife Ups Risk of Cognitive Decline - Medscape, 4/1/22 - "scientists paired self-reported antibiotic use of 14,000 middle-aged nurses with outcomes on neuropsychological tests conducted 7 years later. The results revealed that those nurses who took antibiotics for at least 2 months during a period of 4 years had lower scores on tasks involving memory, learning, attention, and psychomotor speed. Overall, the negative effects of antibiotics on cognition were comparable to those caused by 3 to 4 years of aging"

Does alkaline water actually have health benefits? - womenshealthnetwork.com - "Synthetic alkaline water can be divided into two groups. One is purified water with added trace minerals. The second is produced by electrolysis and it’s even more artificial. A machine separates the hydrogen (acid-forming) and hydroxyl (alkalizing)components of water and renders two waters, one highly acidic and the other highly alkalizing ... The label on this kind of “alkalizing water” might say it was made by electrolysis. Such waters can have a pH of 9 or above — high enough to inactivate pepsin and decrease stomach acid production. In fact, the only medically approved use of these high pH waters is to treat acid reflux in Japan and Korea. Proponents of alkaline water made through electrolysis make broad claims about its health effects but to date, the only official medical use is for excess stomach acid." - Note: I had to take my wife to the E.R. one because she drank the electrolysis form.

Ivermectin is the signature example of politics trumping health - CNET, 3/31/22 - "The former president’s advocacy was halting and constrained, recognizing that there was more political value in standing against the “so-called experts” than in trying to persuade people to protect themselves against the virus. So his most fervent supporters went looking for more miracles. Florida embraced those antibody treatments. Others began to hype the drug ivermectin ... There was never any evidence that ivermectin was particularly effective at treating coronavirus infections. A smattering of studies suggested that there might be some benefit, but they were limited in scale. By March 2021, the Food and Drug Administration was warning that it hadn’t found any demonstrable benefit from taking the drug to treat covid. But then the delta variant of the coronavirus began to spread, causing particular devastation in states that were less vaccinated and, relatedly, had shown more support for Trump. So many people in those areas sought out ivermectin, convinced that some cure existed beyond the highly effective vaccine promoted by the Biden administration and the “experts.” ... We now know with a great deal of confidence that ivermectin does not show any appreciable benefit in treating covid-19. In fact, “volunteers who took ivermectin in the first three days after a positive coronavirus test turned out to have worse outcomes than did those in the placebo group,” as the New York Times reported." - Note: People want to believe lies and/o miracles. It works both ways. With politics and so-called big pharma. Big pharma might be dishonest but they have a long way to go to catch up with some politicians selling ivermectin and hydroxychloroquine.

Babies exposed to cannabis in the womb may be at risk for obesity, high blood sugar - Science Daily, 3/31/22 - "up to 22% of pregnant women had detectable levels of cannabinoids in their body. Women who use cannabis, both tetrahydrocannabinol (THC) and cannabidiol (CBD), during pregnancy could be putting their child at risk for low birth weight and behavioral problems. Exposure to cannabinoids may also increase the child's future risk of obesity and high blood sugar ... cannabis use during pregnancy was linked to increased fat mass percentage and fasting glucose levels in 5-year-old children"

 

 

Abstracts from this week:

Trehalose inhibits ferroptosis via NRF2/HO-1 pathway and promotes functional recovery in mice with spinal cord injury - Aging (Albany NY) 2022 Apr 10 - "Spinal cord injury (SCI) is the main cause of severe damage to the central nervous system and leads to irreversible tissue loss and neurological dysfunction. Ferroptosis is a cell death pattern, newly discovered in recent years. Ferroptosis is an oxidizing cell death induced by small molecules, and is an iron-dependent process caused by the imbalance between the generation and degradation of lipid reactive oxygen species (ROS) in cells. As an antioxidant, trehalose can effectively prevent lipid peroxidation. Studies have reported that trehalose can improve the prognosis of SCI ... trehalose inhibited the expansion of cavities in the nerve tissue of mice with SCI, inhibited neuron loss, and improved functional recovery. In terms of mechanism, our results indicate that the neuroprotective effect of trehalose is due to the activation of the NRF2/HO-1 pathway, which in turn inhibits ferroptosis and ferroptosis-related inflammation" - See trehalose at Amazon.com.

Protective Effect of Catheter Ablation of Atrial Fibrillation on the Renal Function in Patients With Hypertrophic Cardiomyopathy - Am J Cardiol 2022 Apr 6 - "During a mean follow-up period of 34 ± 27 months, sinus rhythm was maintained in 36 patients (80%) after 1.7 ± 0.8 ablation procedures. The eGFR significantly decreased from baseline to 3 months (p <0.01) and from baseline to 1 year (p <0.01) in the control group, whereas the eGFR in the ablation group was maintained both from baseline to 3 months (p = 0.94) and from baseline to 1 year (p = 1.00) after the CA. The change in the eGFR between baseline and 12 months was significantly smaller in the ablation group than in the control group (p <0.01). After logistic regression analysis, CA of AF was the independent predictor of an improvement of eGFR (odds ratio 2.81"

Memory enhancement effect of saponins from Eleutherococcus senticosus leaves and blood-brain barrier-permeated saponins profiling using a pseudotargeted monitoring strategy - Food Funct 2022 Mar 21 - "Dried Eleutherococcus senticosus leaves (ESL), also known as Siberian ginseng tea, are beneficial for human neural disorders. Our previous studies showed that the aqueous extract of ESL enhanced memory in mice, and its saponin fraction (ESL-SAP) exhibited promising neuroprotective activities in vitro; however, the in vivo neurally related effect, bioactive material basis, and possible mechanism of action of ESL-SAP have not been investigated. Here, a series of memory and learning tests were carried out, and the results evidenced a significant enhancement effect of ESL-SAP ... blood-brain barrier (BBB) ... A further network pharmacology analysis was conducted on BBB-permeated compounds, which indicated that the in vivo mechanism of ESL-SAP might be effective through multiple targets and pathways, such as the AGE-RAGE signaling pathway and PI3K-Akt signaling pathway, to exert neuroprotective effects. Moreover, the molecular docking experiments demonstrated that key BBB-transferred saponins primarily interacted with targets HRAS, MAPK1, and MAPK8 to produce the neuroprotective effect" - See ginseng at Amazon.com.

The effects of metformin and forskolin on sperm quality parameters and sexual hormones in type II diabetic male rats - Andrologia 2022 Apr 8 - "Treating diabetic rats with metformin and forskolin resulted in significant improvement in sperm quality parameters, increased testosterone levels, reduced oxidative stress in blood and testicular tissue, and decreased blood sugar, and Bax to Bcl-2 ratio level. Although the combination of metformin with forskolin had a higher effect in some parameters such as testosterone levels compared to treatment with metformin or forskolin alone, this combination had not shown a synergistic effect in all the sperm quality parameters. Metformin and forskolin are effective anti-diabetic agents, which significantly improve the sperm quality and sexual hormone levels in diabetic rats. Combining metformin and gorskolin resulted in significantly better testosterone level and antioxidant activity in blood serum without significant effect on sperm quality of diabetic rats" - See metformin at ReliableRX and forskolin at Amazon.com.

A critical evaluation of risk to reward ratio of quercetin supplementation for COVID-19 and associated comorbid conditions - Phytother Res 2022 Apr 8 - "The interim results of the large, multinational trials on coronavirus disease 2019 (COVID-19) using a combination of antiviral drugs appear to have little to no effect on the 28-day mortality or the in-hospital course. Therefore, there is a still vivid interest in finding alternate re-purposed drugs and nutrition supplements, which can halt or slow the disease severity ... The present review is tempting to suggest that, based on circumstantial scientific evidence and preliminary clinical data, the flavonoid quercetin can ameliorate COVID-19 infection and symptoms acting in concert on two parallel and independent paths: inhibiting key factors responsible for SARS-CoV-2 infections and mitigating the clinical manifestations of the disease in patients with comorbid conditions" - See quercetin at Amazon.com./p>

Folecitin Isolated from Hypericum oblongifolium Exerts Neuroprotection against Lipopolysaccharide-Induced Neuronal Synapse and Memory Dysfunction via p-AKT/Nrf-2/HO-1 Signalling Pathway - Evid Based Complement Alternat Med 2022 Mar 28 - "Neurodegenerative diseases, especially Alzheimer's disease (AD), are characterised with neuronal synapse and memory dysfunction, and thus, there is an urgent need to find novel therapeutic medicines that can target different pathways to restore the deficits. In this investigation, we assessed the medicinal potency of folecitin (a flavonoid isolated from Hypericum oblongifolium Wall.) against lipopolysaccharide (LPS)-induced amyloidogenic amyloid beta (Aβ) production pathway-mediated memory impairment in mice. ... folecitin significantly decreased LPS-induced apoptotic proteins; expressed BAX, PARP-1, and caspase-3 proteins; and inhibited BACE1 that cleaves transmembrane amyloid precursor protein and the amyloidogenic Aβ production pathway. Folecitin restored both preneural and postneuronal synapse, accompanied by the improvement in memory impairment. Moreover, folecitin significantly activated endogenous antioxidant proteins Nrf-2 and HO-1 by stimulating the phosphorylation of Akt proteins. These findings indicate that folecitin might be a promising target for developing novel medication to treat neurodegenerative disorders caused by neurotoxins" - See St. John's wort at Amazon.com.

SStatin Use Is Associated With a Lower Risk of Blepharitis: A Population-Based Study -Front Med (Lausanne) 2022 Mar 15 - "Blepharitis is a common eye disorder that may be overlooked by patients and clinical practitioners. The symptoms of blepharitis often manifest as irritation, a burning sensation, grittiness, and itchiness and may decrease visual acuity if not treated promptly. Meibomian gland dysfunction (MGD), a common cause of blepharitis, is believed to be associated with increased inflammatory marker levels that may disrupt the composition of lipids produced by the sebaceous glands in the eyelids and ultimately cause tear film instability ... The incidence of blepharitis was 3.04% with statin treatment and 3.72% without statin treatment (p < 0.001). Patients who used statins had a lower risk of developing blepharitis [adjusted hazard ratio (aHR): 0.746, p < 0.001] than those who did not.

These results indicate that luteolin might ameliorate methamphetamine-induced podocyte pathology through GSK3β-p-Tau axis" - See luteolin products at Amazon.com.

Improvement in the Blood Urea Nitrogen and Serum Creatinine Using New Cultivation of Cordyceps militaris - Evid Based Complement Alternat Med 2022 Mar 23 - "Chronic kidney disease (CKD) is a critical public health issue with a huge financial burden for both patients and society worldwide. Unfortunately, there are currently no efficacious therapies to prevent or delay the progression of end-stage renal disease (ESRD). Traditional Chinese medicine practices have shown that Cordyceps militaris (C. militaris) mycelia have a variety of pharmacologically useful properties, including antitumor, immunomodulation, and hepatoprotection. However, the effect of mycelial C. militaris on CKD remains unclear ... nvestigated the effects of C. militaris mycelia on mice with CKD using four types of media: HKS, HKS with vitamin A (HKS + A), CM, and CM with vitamin A (CM + A) ... The results at day 10 revealed that the levels of blood urea nitrogen (BUN) were significantly lower in the HKS (41%), HKS + A (41%), and CM + A (34%) groups compared with those in the corresponding control groups (nephrectomic mice). The level of serum creatinine in the HKS + A group decreased by 35% at day 10, whereas the levels in the HKS and CM + A groups decreased only by 14% and 13%, respectively, on day 30. Taken together, this is the first report using four new media (HKS, HKS + A, CM, and CM + A medium) for C. militaris mycelia. Each medium of mycelial C. militaris on CKD exhibits specific effect on BUN, serum creatinine, body weight, total protein, and uric acid" - See Cordyceps at Amazon.com.

Metformin to treat Huntington disease: a pleiotropic drug against a multi-system disorder - Mech Ageing Dev 2022 Mar 30 - "Huntington disease (HD) is a neurodegenerative disorder produced by an expansion of CAG repeats in the HTT gene. Patients of HD show involuntary movements, cognitive decline and psychiatric impairment. People carrying abnormally long expansions of CAGs (more than 35 CAG repeats) produce mutant huntingtin (mHtt), which encodes tracks of polyglutamines (polyQs). These polyQs make the protein prone to aggregate and cause it to acquire a toxic gain of function. Principally affecting the frontal cortex and the striatum, mHtt disrupts many cellular functions ... Several studies reported that metformin, a widely-used anti-diabetic drug, is neuroprotective in models of HD ... Metformin is a pleiotropic drug, modulating different targets such as AMPK, insulin signalling and many others. These molecules regulate autophagy, chaperone expression, and more, which in turn reduce mHtt toxicity. Moreover, metformin alters gut microbiome and its metabolic processes" - See metformin at ReliableRX.

The Effect of Sacubitril/Valsartan Treatment on Cardiac and Renal Functions of a Patient With Cardiorenal Syndrome Type 4 and Stage 5 CKD After More Than Three Years of Follow-Up - Front Med (Lausanne) 2022 Mar 11 - "In our hospital, she received sacubitril/valsartan treatment for at least 40 months. The symptoms of HF relieved, and the indices of cardiac function improved. In addition, the patient's renal function was stable. During the treatment, the dosage of sacubitril/valsartan needed to be adjusted to achieve the optimal therapeutic effect. Follow-up results showed that she achieved cardiac function of New York Heart Association (NYHA) class II with an ejection fraction of 0.60 and E/A > 1 indicated by echocardiogram, and did not develop hyperkalemia. In summary, the improvement of cardiac and renal functions of the CRS4 patient was associated with the long-term sacubitril/valsartan treatment"

Comparison of Trials Using Ivermectin for COVID-19 Between Regions With High and Low Prevalence of Strongyloidiasis - JAMA. 3/21/22 - "In this meta-analysis of 12 trials including 3901 patients, strongyloidiasis prevalence was found to interact with the RR of mortality for ivermectin as a treatment for COVID-19. No evidence was found to suggest ivermectin has any role in preventing mortality among patients with COVID-19 in regions where strongyloidiasis was not endemic" - Note: In layman's terms, seems like what they're saying is that if strongyloidiasis is an underlying condition, ivermectin will cure that underlying condition and reduce mortality. But only 8% have the strongyloidiasis parasite and nearly all of them are in tropic or sub-tropic climates.

Lipid metabolism disorders and lipid mediator changes of mice in response to long-term exposure to high-fat and high sucrose diets and ameliorative effects of mulberry leaves - Food Funct 2022 Mar 31 - "Mulberry leaves exhibit anti-lipogenic and lipid-lowering effects. However, the lipid biomarkers and underlying mechanisms for the improvement of the action of mulberry leaves on obesity and lipid metabolism disorders have not been sufficiently investigated yet ... mulberry leaf water extract (MLWE) ... Our results showed that MLWE supplementation not only decreased body weight gain, serum total triglycerides, low-density lipoprotein cholesterol, alanine transaminase and aspartate transaminase levels, but also increased the serum level of high-density lipoprotein cholesterol. In addition, MLWE supplementation also ameliorated hepatic steatosis and lipid accumulation" - See mulberry leaf extract at Amazon.com.

Low and High-Density Lipoprotein Cholesterol and 10-Year Mortality in Community-Dwelling Older Adults: The Shanghai Aging Study - Front Med (Lausanne) 2022 Mar 8 - "Using the highest quintile of LDL-C (≥4.10 mmol/L) as a reference, the lowest quintile of LDL-C (<2.61 mmol/L) was associated with the highest risk of mortality, after adjusting for confounders (HR 1.67; 95% CI 1.26-2.21), exclusion of death within the first 2 years of follow-up (HR 1.57; 95% CI 1.17-2.11), and exclusion of functionally impaired participants (HR 1.46; 95% CI 1.07-2.00). A U-shape relationship was found between HDL-C level and the mortality risk. Using the third quintile of HDL-C (1.21-1.39 mmol/L) as a reference, HR (95% CI) was 1.46 (1.09-1.95) for the lowest quintile (<1.09 mmol/L) and 1.45 (1.07-1.96) for the highest quintile (≥1.61 mmol/L) of HDL-C, after adjusting for confounders; and 1.57 (1.15-2.15) for the lowest quintile and 1.45 (1.04-2.01) for the highest quintile of HDL-C, after exclusion of death within the first 2 years of follow-up; and 1.55 (1.11-2.16) for the lowest quintile and 1.42 (1.00-2.02) for the highest quintile of HDL-C, after exclusion of functionally impaired participants. ... We found an inverse association of LDL-C and a U-shape relationship of HDL-C with long-term all-cause mortality in a cohort with community-dwelling older Chinese adults. Levels of LDL-C and HDL-C are suggested to be managed properly in late life"

Effect of Early Treatment with Ivermectin among Patients with Covid-19 - NEJM, 3/30/22 - "Treatment with ivermectin did not result in a lower incidence of medical admission to a hospital due to progression of Covid-19 or of prolonged emergency department observation among outpatients with an early diagnosis of Covid-19" - See [10News] [Medscape] I take a lot of crap for saying that it doesn't work. If might help if you have that parasite as an underlying condition. The way I understand it is that that parasite is only common is certain parts of the world and most people in the U.S. don't have it. See the article in my last newsletter. Seems like there would be a test for parasites. I do that test before I took snake oil for Covid.

Can we rely on total testosterone measurement to exclude hypogonadism in erectile dysfunction? - Int J Impot Res 2022 Mar 28 - "Although male hypogonadism (MH) is a prevalent comorbidity in patients presenting for erectile dysfunction (ED), its screening relies solely on total testosterone (TT). Ageing and other conditions can increase sex hormone-binding globulin (SHBG) and lower free testosterone (FT) causing symptomatic MH despite normal TT. The primary objective was to measure the prevalence of normal TT/low FT among patients presenting for ED ... Normal TT/low cFT is frequent and can be missed by current screening recommendations for MH in patients presenting for ED. Ageing seems to be the main culprit as elevated SHBG prevalence increases steeply after the sixth decade. TT cannot solely be relied on to exclude biochemical MH in patients presenting for ED, especially in patients over 60 years old"
