Recent Longevity News for the week ending 6/29/22

Low-Carb, High-Fat Diet Improves A1c, Reduces Liver Fat: Study - Medscape, 6/27/22 - "A low-carbohydrate, high-fat (LCHF) diet reduced the progression of nonalcoholic fatty liver disease (NAFLD), and despite no calorie restriction, participants with both NAFLD and type 2 diabetes lost 5.8% of their body weight ... Basically, if you have fat in your liver, you will benefit from eating fat ... Those on the LCHF diet consumed an average of 61% energy from fat, 13% from carbohydrates, and 23% from protein, compared with the low-fat diet, which comprised an average of 29% energy from fat, 46% from carbohydrates, and 21% from protein ... It's a lot of fat and corresponds to a quarter of a liter of olive oil per day ... The LCHF diet was primarily comprised of unsaturated fats — for example, avocado, oil, nuts, and seeds — but also included saturated fats, such as cheese, cream, and high-fat dairy products ... We found that the LCHF diet improved diabetes control, it reduced the fat in the liver, and, even though they're eating as many calories as they were used to until they were full, they lost 5.8% of body weight"

COVID-19 Tied to Increased Risk of Alzheimer's, Parkinson's Disease - Medscape, 6/27/22 - "The study included 43,262 individuals with a positive COVID test without a history of influenza A/B in the past year and 876,356 without a positive COVID test. It also included 1474 individuals with community acquired pneumonia without a history of COVID and 8102 with influenza A or B ... After 12 months, the relative risk (RR) for AD was 3.4 (95% CI, 2.3 - 5.1) in the COVID positive group vs the COVID negative group ... These results were rather unexpected, said Zarifkar. "I would have expected a small increase, but the extent of the increase was quite surprising." ... The findings were similar for PD, where there was a 2.2-fold increased risk of a PD diagnosis within the first 12 months in COVID positive individuals compared with COVID negative people ... Part of it could be a result of neuroinflammation, which can lead to a toxic accumulation of beta amyloid in AD and alpha-synuclein in PD ... It can accelerate a neurodegenerative disease already in the making ... As for cerebrovascular disorders, the study showed an increased risk of ischemic stroke in COVID-positive vs COVID-negative subjects at 12 months (RR, 2.87; ... The relatively strong inflammatory response associated with COVID-19, which may create a hypercoagulable state, may help explain the increased ischemic stroke risk in COVID patients"

Flu vaccination linked to 40% reduced risk of Alzheimer's disease - Science Daily, 6/24/22 - "These results underscore the strong protective effect of the flu vaccine against Alzheimer's disease ... Since there is evidence that several vaccines may protect from Alzheimer's disease, we are thinking that it isn't a specific effect of the flu vaccine ... Instead, we believe that the immune system is complex, and some alterations, such as pneumonia, may activate it in a way that makes Alzheimer's disease worse. But other things that activate the immune system may do so in a different way -- one that protects from Alzheimer's disease. Clearly, we have more to learn about how the immune system worsens or improves outcomes in this disease"

Global AFib study finds simple ablation has best outcomes - Science Daily, 6/21/22 - "using advanced image-guided technology to more aggressively target diseased areas of the heart that cause arrythmias didn't lead to better outcomes for patients -- and put some at higher risk of strokes ... Simplicity is key. Don't ablate too much, especially at advanced stages ... Too much ablation is not helping our patients today. It is putting them at higher risk. This is a practice-changing finding from our study"

Empagliflozin Eyed for Outpatient Chronic Hyponatremia - Medscape, 6/21/22 - "Empagliflozin is a potential treatment for outpatients with chronic hyponatremia due to the syndrome of inappropriate antidiuresis (SIAD) ... Hyponatremia, defined as a serum sodium level below 135 mmol/L, is the most common electrolyte disorder in both the inpatient and outpatient settings. SIAD is one of its main causes, whereby impaired antidiuretic hormone regulation leads to a reduction in free water excretion and water retention in the kidney, with subsequent hypotonic hyponatremia ... Serum sodium levels remained stable with placebo while increasing from 130 mmol/L to 134 mmol/L with empagliflozin, giving a corresponding treatment effect of 4.1 mmol/L (P = .004). The increase took place during the first week of treatment and plasma sodium levels remained stable through subsequent weeks ... there's accumulating evidence that these patients have cognitive impairments such as attention deficit, that they are unstable when walking with a propensity to fall, and that they have increased risk for osteoporosis and fractures, and even death" - Note: Sounds like that could be a bad think if you blood sodium is high. - See empagliflozin inhousepharmacy.vu.

Abstracts from this week:

A high carbohydrate diet with a low glycaemic index improves training effects in male endurance athletes - Int J Food Sci Nutr 2022 Jun 26 - "The present study investigated the effect of a 4-week high fat low carbohydrate (HFLC-G) versus high carbohydrate low glycaemic (LGI-G) or high glycaemic (HGI-G) diet on power output at lactate thresholds, peak oxygen uptake and peak performance during an incremental cycle test in 28 male endurance athletes. All participants showed improved levels of power output at the lactate thresholds with a more pronounced effect in the HFLC-G and LGI-G. In the HFLC-G peak performance (-11.6 ± 16.3 W) decreased, while in the LGI-G (9.20 ± 13.8 W) and HGI-G (9.89 ± 12.8 W) peak performance increased (p = 0.009). In summary, the LGI-G showed comparable training adaptations as the HFLC-G at submaximal intensities without limiting the ability to perform at high intensities. Compared to a HFLC and HGI diet, the LGI diet in this study seemed to be advantageous during submaximal and high intensities resulting from an improved metabolic flexibility"

Curcumin can increase the sensitivity of NSCLC to cisplatin through an ER stress pathway and thus can be served as one of the molecular targets for overcoming the cisplatin resistance" - See curcumin at Amazon.com.

Nanocurcumin substantially alleviates noise stress-induced anxiety-like behavior: the roles of tight junctions and NMDA receptors in the hippocampus - Behav Brain Res 2022 Jun 21 - "Environmental noise stress affects non-auditory brain regions such as the hippocampus; an area of the brain implicated in cognition and emotion. Recent experimental data indicate that dysfunction of the blood-brain barrier (BBB) and overexpression of NMDA receptors may cause anxiety. In this experiment, we evaluated the effect of nanocurcumin on anxiety-like behavior and the expression of tight junctions and NMDA receptor subunits in the hippocampus of rats exposed to traffic noise. Forty rats were assigned to control (CON), stress (ST), nanocurcumin (NC), and nanocurcumin+stress (NC+ST) groups ... Our findings showed that noise exposure promotes stress and anxiety and impairs the NMDA receptor structure and BBB integrity. The nanocurcumin treatment displayed partly restored the destructive effects of noise exposure" - See curcumin at Amazon.com.

The reason I keep plugging the Touch is that's it's the only one that's reasonably price that dispenses the water at the optimum 205 degrees. The other's don't even come close at around 170 degrees which is why their coffee tastes like piss.
These hold 20 oz. (three cups of coffee) and fit in a Tesla console cup holder.  Great for something like a day at Yosemite. You might need two though.

Associations between plasma tryptophan and indole-3-propionic acid levels and mortality in patients with coronary artery disease - Am J Clin Nutr 2022 Jun 21 - "CAD patients with the highest quartile of tryptophan and IPA levels had multivariable-adjusted hazard ratios of 0.62 (95% confidence interval [CI], 0.43, 0.89) and 0.71 (95% CI 0.50, 0.99), respectively, for cardiovascular mortality and 0.67 (95% CI, 0.50, 0.90) and 0.75 (95%CI 0.57, 0.99), respectively, for all-cause mortality compared with that in CAD patients in the lowest quartile.

Nicotinamide riboside and caffeine partially restore diminished NAD availability but not altered energy metabolism in Alzheimer's disease - Aging Cell 2022 Jun 21 - "The redox co-factor nicotinamide adenine dinucleotide (NAD) declines with age, and NAD deficits are specifically associated with dysfunctional energy metabolism in late-onset Alzheimer's disease (LOAD). Nicotinamide riboside (NR), a dietary NAD precursor, has been suggested to ameliorate the aging process or neurodegeneration. We assessed whether NR with or without caffeine, which increases nicotinamide mononucleotide transferase subtype 2 (NMNAT2), an essential enzyme in NAD production, modulates bioenergetic functions in LOAD ... although NR and caffeine can partially restore diminished NAD availability, increasing NAD alone may not be sufficient to boost or restore energy metabolism in brain aging or alter aberrant energy management in LOAD. Nicotinamide riboside might still be of value in combination with other agents in preventive or therapeutic intervention strategies to address the aging process or age-associated dementia" - See nicotinamide riboside at Amazon.com.

Cost-Effectiveness of Catheter Ablation Versus Antiarrhythmic Drug Therapy in Atrial Fibrillation: The CABANA Randomized Clinical Trial - Circulation 2022 Jun 21 - "In the CABANA trial (Catheter Ablation vs Antiarrhythmic Drug Therapy for Atrial Fibrillation), catheter ablation did not significantly reduce the primary end point of death, disabling stroke, serious bleeding, or cardiac arrest compared with drug therapy by intention-to-treat, but did improve the quality of life and freedom from atrial fibrillation recurrence. In the heart failure subgroup, ablation improved both survival and quality of life. Cost-effectiveness was a prespecified CABANA secondary end point ... Catheter ablation of atrial fibrillation was economically attractive compared with drug therapy in the CABANA Trial overall at present benchmarks for health care value in the United States on the basis of projected incremental QALYs but not LYs alone"

Doxorubicin-induced senescence in normal fibroblasts promotes in vitro tumour cell growth and invasiveness: the role of Quercetin in modulating these processes - Mech Ageing Dev 2022 Jun 18 - "Ageing is a complex biological phenomenon representing the major risk factor for developing age-related diseases, such as cardiovascular pathologies, neurodegenerative diseases, and cancer. Geroscience, the new vision of gerontology, identifies cellular senescence as an interconnected biological process that characterises ageing and age-related diseases. Therefore, many strategies have been employed in the last years to reduce the harmful effects of senescence, and among these, the most intriguing ones use nutraceutical compounds. Here we show that a pre-treatment with Quercetin, a bioactive flavonoid present in many fruits and vegetables, increasing cellular antioxidant defence, can alleviate Doxorubicin (Doxo)-induced cellular senescence in human normal WI-38 fibroblasts. Furthermore, our work demonstrates that Quercetin pre-treatment, reducing the number of senescent cells and the production of the senescence-associated secretory phenotype (SASP) factors, can decrease the pro-tumour effects of conditioned medium from Doxo-induced senescent fibroblasts on osteosarcoma cells. Overall, our findings are consistent with the hypothesis that targeting senescent cells can be an emerging strategy for cancer treatment, especially in elderly patients, in which senescent cells are already abundant in several tissues and organs" - See quercetin at Amazon.com.

Quercetin in Tonglong Qibi decoction ameliorates testosterone-induced benign prostatic hyperplasia in rats by regulating Nrf2 signalling pathways and oxidative stress - Andrologia 2022 Jun 20 - "Benign prostatic hyperplasia (BPH) is a common urological disease in older males. Existing pharmacotherapy shows several side effects, and the exploration of new therapeutic strategies is of high significance. Tonglong Qibi (TQ) decoction was proved to ameliorate BPH, while the underlying mechanisms are still unclear. In the current study, we explored the anti-BPH effects of TQ in vivo and identified its main therapeutic component and the underlying mechanisms in vitro. We demonstrated that TQ mitigated BPH in rats and showed no toxicity to the liver and reproductive system. Network pharmacology identified quercetin as the main component in TQ treating BPH. Quercetin reduced proliferation, oxidative stress, and increased Nrf2 expression in hyperplastic prostate epithelial cells. These findings indicate that quercetin in TQ alleviates BPH via inhibiting oxidative stress and activating the Nrf2 signalling pathway" - See quercetin at Amazon.com.

Self-reported marijuana use and cardiac arrhythmias (from the Multiethnic Study of Atherosclerosis) - Am J Cardiol 2022 Jun 17 - "Compared with never users, participants reporting current use of marijuana (n = 40, 3%) had more supraventricular tachycardia/day (adjusted geometric mean ratio [GMR] 1.42, 95% confidence interval [CI] 0.87 to 2.32), more premature atrial contractions/hour (GMR 1.22, 95% CI 0.72, 2.13), and more NSVT/day (GMR 1.28, 95% CI 0.95 to 1.73); although, CIs overlapped 1. Additionally, more frequent marijuana use was associated with more runs of NSVT/day (GMR 1.56, 95% CI 1.13, 2.17). In conclusion, our results suggest that current marijuana use may be associated with a greater burden of arrhythmias"
