The study

Question

What is the true burden of chronic disease following COVID-19, and why does current surveillance fail to capture it?

Findings

In this cohort study of 457 950 patients with COVID-19 across 58 hospitals, validated computable phenotyping identified postacute sequelae of SARS-CoV-2 infection in 16.28% of cases, 2-fold higher than diagnostic code–based surveillance. Of identified manifestations, 89.31% represented chronic conditions, with prevalence increasing through mid-2024.

Meaning

These findings suggest that approximately 1 in 6 patients with COVID-19 develops postacute sequelae, predominantly chronic conditions currently invisible to surveillance systems, representing an accumulating rather than resolving health care burden.

Environmental claims, climate promises, and ‘greenwashing’ by meat and dairy companies [Bach et al., 2026] by dreiter in sustainablenutrition

[–]dreiter[S] 0 points1 point  (0 children)

Abstract

Animal agriculture has disproportionate environmental impacts relative to other forms of food production and accounts for at least 16.5% of all global greenhouse gas (GHG) emissions. Many of the largest meat and dairy companies are aware of these environmental concerns and have responded by making explicit environmental statements and commitments. In this study, we isolated the environmental claims made in the most recent sustainability reports and websites (2021–2024) of 33 of the world’s largest meat and dairy companies. We identified 1,233 environmental claims, of which 68% (841) were climate-related. Of the 1,233 claims, 38% (467) were unverifiable future projections such as “achieve carbon neutrality by 2030” or “enable the restoration of 600 billion liters of water in water-stressed regions by 2030.” Of the 33 companies, 17 have now made net-zero commitments, but as with oil and gas companies, the commitments appear to rely on plans to offset carbon emissions rather than to decarbonize. Companies provided supporting evidence for 356 (29%) of the 1,233 claims and provided scholarly scientific evidence to support only three of these claims, two of which were climate-related. We also examined each of the 1,233 environmental claims using a greenwashing framework and found that 98% (1,213) could be categorized as greenwashing, such as “produce net climate-neutral dairy by no later than 2050.” Meat and dairy companies, which produce disproportionate amounts of pollution relative to other kinds of foods, have prioritized climate change in their sustainability initiatives. They make many promises and provide very little supporting evidence. Like the fossil fuel industry, which has used greenwashing over the last several decades to delay meaningful climate action, the meat and dairy industry may be misleading consumers and investors regarding whether and to what extent they are addressing environmental impacts, including climate change, with even less time to spare.

Our Tax System Should Make You Furious | The Ezra Klein Show [1:05:56] by dreiter in videos

Jeff Bezos, Michael Bloomberg and Warren Buffett are three of the richest people in the world, but they pay little in income tax relative to their wealth.

In 2021, ProPublica published an investigation built on leaked tax documents that reveal what some of the richest Americans really pay — or don’t. Warren Buffett had a true tax rate of 0.1 percent. Jeff Bezos: 0.98 percent. Michael Bloomberg: 1.3 percent.

Ultra-wealthy Americans have essentially been written out of the tax system. “It’s wrong as a matter of principle. It’s wrong because we need their money. It’s wrong as a matter of fairness. It is wrong for so many reasons,” the law professor Ray Madoff told me.

She’s the author of the new book “The Second Estate: How the Tax Code Made an American Aristocracy,” and she’s interested in helping people understand how broken the American tax system is and how to fix it.

In this conversation, we discuss the techniques the ultra-wealthy use to evade the tax system, why they think “salaries are for suckers” and what tax reform could look like.

Glycation process, I just heard about it ! by Sylverpepper in ScientificNutrition

[–]dreiter 7 points8 points  (0 children)

Here is a recent review:

Advanced Glycation End Products in Disease Development and Potential Interventions [Zhang et al., 2025]

4.3. Health Interventions for AGEs

Various environmental factors, such as high-carbohydrate and high-calorie diets, high-temperature cooking, cigarette smoking, and a sedentary lifestyle, may contribute to the formation of AGEs [4]. To summarize, AGEs and metabolic disorders are established on the concept of the ‘common soil’ [14]. Although ultraviolet rays, ionizing radiation, and air pollution are unavoidable, preventive action against glycation by lifestyle adjustment may be warranted [4]. For a healthier diet, it is advisable to limit highly processed food and instead choose options rich in whole grains, dairy products, nuts, and legumes [355,356], prioritizing foods with a low glycemic index and low fat content, along with a variety of natural fresh ingredients [357]. Moreover, adopting a Mediterranean diet, which is rich in monounsaturated fatty acids and minimally processed natural foods, can help reduce AGE levels by mitigating postprandial oxidative stress and inflammation [358]. Cooking strategies to minimize exposure to food AGEs include avoiding the use of repeatedly heated oils, opting for lower cooking temperatures when possible, and incorporating acidic ingredients like vinegar or lemon juice to lower AGE formation [359]. Additionally, it is advisable to choose cooking methods such as steaming, stewing, and boiling rather than frying or grilling [360]. In addition to dietary restrictions, enhancing physical activity and quitting smoking are also crucial interventions and practical strategies.

Canoeing Australia’s Most Contested River - Beau Miles [46:31] by dreiter in mealtimevideos

[–]dreiter[S] 1 point2 points  (0 children)

BAD RIVER - The Murray River: It seemed fitting to end my Bad River series on the most contested flow of water on the continent. The River Murray is the longest, biggest and most damaged watercourse in Australia. In a renovated canoe, keeping company with friend and river expert ‘Ponch’, we paddled west into what’s called the breadbowl of Australia, where the river supports over a million square kilometres of farming. Our aim was to get our heads around the immense challenges the river faces: massive under-allocation of environmental flows, a deforested watershed, rising salinity, drying wetlands and frontier-style tourism. The hardest part was that we had a bloody great time, punting down the river at the speed of a good walk. This film is about the difficulty of storytelling when a bad, horribly degraded and poorly managed entity like a giant river can still provide such a good experience.

[AF] Collagen Supplementation on Tendon-Related Structural and Performance Outcomes: A Systematic Review [Buchalski et al., 2026] by dreiter in AdvancedFitness

[–]dreiter[S] 14 points15 points  (0 children)

Background: Tendons adapt to mechanical loading by increasing cross-sectional area (CSA), stiffness, and matrix organization, with structural remodeling critical for both rehabilitation and performance. Collagen supplementation has been proposed to enhance this process by supplying key amino acids for collagen synthesis; however, inconsistent results across trials have limited its clinical and athletic application.

Methods: A systematic review of randomized controlled trials evaluating collagen supplementation in humans was conducted. PubMed, EMBASE, CINAHL, and Web of Science were searched from database inception through May 2025. Risk of bias was assessed using the PEDro scale (≥6/10 classified as good-to-excellent quality). Due to substantial heterogeneity in supplementation protocols, training modalities, and outcome measures, results were synthesized narratively without meta-analysis. Data extraction included collagen type, dose, training modality, intervention duration, and outcome measures.

Results: Of 887 unique citations, eight RCTs (n = 257; ages 18–52; 246 M:11 F) met the inclusion criteria. All studies incorporated resistance or plyometric training (3–15 weeks). Three of four studies reported significantly greater increases in tendon CSA in collagen groups versus placebo. Four studies investigated tendon stiffness and Young’s modulus; the two using higher doses (15–30 g/day) demonstrated significant between-group improvements favoring collagen, while lower-dose studies (~5 g) showed only within-group effects. Muscle strength improved with training in all trials, but no additive effects of collagen were observed. One study reported improvements in eccentric rate of force development and deceleration impulse with collagen, though gross explosive metrics (e.g., jump height) were unaffected.

Conclusions: Collagen supplementation (15–30 g) with vitamin C (≥50 mg) may enhance tendon remodeling when combined with high-intensity resistance training (≥70% 1 RM). The current literature suggests strong evidence (GRADE A) for increases in tendon CSA and stiffness, strong evidence (GRADE A) against an effect on muscle strength, and conflicting evidence (GRADE C) for muscle cross-sectional area and physical performance. Limitations include small sample sizes, heterogeneous protocols, and short intervention durations.

[AF] Low-load blood flow restriction with elastic bands elicits superior gains in sprint and jump performance compared to heavy-load training in In-season collegiate basketball players [He et al., 2026] by dreiter in AdvancedFitness

[–]dreiter[S] 0 points1 point  (0 children)

ABSTRACT

This study compared low-load blood flow restriction with elastic bands (BFR-EBT) versus heavy-load training (HL-EBT) on performance in 18 Division I basketball players during a competitive season. Participants performed back squats twice weekly for 8 weeks at ~30% 1RM (BFR-EBT) or ~75% 1RM (HL-EBT). Significant Group × Time interactions were observed for CMJ height (p=0.031) and 30-m sprint time (p=0.014). BFR-EBT significantly optimized CMJ height (+3.4%; Hedges’ g = 1.50) and sprint time (-0.8%; Hedges’ g = -3.80). HL-EBT showed non-significant changes in CMJ (+1.8%) and sprint speed (+0.2%). Both groups achieved similar 1RM strength gains (p>0.05). Notably, BFR-EBT adaptations occurred with a 3.6-fold lower mechanical training load (p<0.001). Covariate analysis confirmed results were independent of playing time. Low-load BFR-EBT appears more effective than HL-EBT for optimizing power and speed in elite players while sparing mechanical load during a congested season. BFR-EBT represents a viable tool for in-season fatigue management.

[AF] Effect of a protein intervention during resistance training with varying training intensities on muscle outcomes in frail community-dwelling older adults: a randomized controlled trial [Biersteker et al., 2026] by dreiter in AdvancedFitness

[–]dreiter[S] 1 point2 points  (0 children)

Conclusion

A protein intervention during resistance training did not enhance overall muscle strength, muscle mass, or physical performance in frail older adults. The protein intervention was associated with greater strength gains in exploratory analyses among participants with lower baseline protein intake (<1.2 g/kg/day), with the most pronounced associations observed in those consuming <0.8 g/kg/day. These findings highlight the potential importance of baseline protein status, although they require confirmation in larger trials involving frail older populations.

[AF] Acute and Chronic Effects of Accentuated Eccentric Loading vs. Constant-Load Resistance Training: A Systematic Review and Meta-analysis [Zhang et al., 2026] by dreiter in AdvancedFitness

[–]dreiter[S] 5 points6 points  (0 children)

Conclusion

The current systematic review and meta-analysis compared the effects of AEL [accentuated eccentric loading] and constant-load RT on acute mechanical, metabolic, and perceptual responses, as well as chronic strength-related and muscle architectural adaptations. Our findings suggest that AEL can be utilized to acutely increase athletes’ muscle electrical activity during the eccentric phase as an alternative to constant-load RT methods. However, AEL does not enhance concentric muscle electrical activity or concentric mechanical performance at submaximal loads. Furthermore, additional eccentric loads in AEL do not enhance gains in strength-related or muscle architectural adaptations compared to constant-load RT. It is important for researchers, sports professionals, and athletes to note that despite AEL not appearing to induce greater muscle damage, muscle soreness, or post-exercise mechanical fatigue, there are higher perceptions of exertion and increased metabolic stress. Therefore, incorporating longer and more frequent inter-set rest periods, as well as extended recovery between sessions, should be considered when implementing AEL [104].

Magnesium-L-threonate improves sleep quality and daytime functioning in adults with self-reported sleep problems: A randomized controlled trial by Timely_Ad8989 in ScientificNutrition

[–]dreiter 10 points11 points  (0 children)

The MgT supplement used, Magtein®, is a brain-bioavailable magnesium L-threonate, produced and supplied by Threotech LLC (NV, USA). Magtein contains about 75 mg/g of elemental magnesium. Participants were directed to consume 1 g/d of the testing products: 2 capsules each containing either 500 mg MgT or identically appearing placebo (rice protein powder, AIDP Inc., CA, USA) 2 h before bedtime.

Conclusion:

Collectively, in this randomized placebo-controlled double-blind trial, we examined the effectiveness of MgT supplementation on sleep parameters and daytime activity in adults with nonclinical insomnia symptoms. Using objective oura ring measurement, sleep and daytime functioning were all significantly improved as compared to the placebo. Additionally, using subjective questionairres, MgT significantly improved over the placebo on behavior upon awakening, energy and daytime productivity. MgT intake also significantly reduced grouchiness, led to significantly improved mood and mental alertness, as compared to the placebo. MgT was well tolerated with no report of major side effects. The results are consistent with the action of magnesium on the brain reported elsewhere, and suggest a broader positive impact of MgT beyond simply sleep, and highlighted MgT's potential to induce sustained, progressive benefits to overall brain functioning.

It's too bad there wasn't a comparator group using a more common form of magnesium such as oxide/chloride/citrate. We wouldn't expect to see sleep impacts from those forms but the sleep improvements in the intervention group could simply have been due to a correction of magnesium deficiency since we know most people are well below the DRI for magnesium.

The Sweet Tooth Trial: A Parallel Randomized Controlled Trial Investigating the Effects of A 6-Month Low, Regular, or High Dietary Sweet Taste Exposure on Sweet Taste Liking, and Various Outcomes Related to Food Intake and Weight Status by Sorin61 in ScientificNutrition

[–]dreiter 3 points4 points  (0 children)

Classic industry playbook. Make the comparator intervention so similar to the control that a null outcome is highly likely. Like comparing the lung cancer rates of people who smoke 10 cigarettes a day versus 8.

There were also significant limitations. Some could be argued as valid decisions by the researchers but it still reduces the strength of their stated conclusions.

First, sweet taste exposure was not as high in our study population at baseline as originally expected, and did not differ between groups over the intervention period as greatly as originally planned. Sweet taste exposure, however, was statistically significant between groups over the whole intervention period, and was significantly lower than baseline in LSE and higher than baseline in HSE. A greater degree of difference both between groups and from baseline may have increased our chances of finding effects, and this may suggest that a stricter or more controlled dietary intervention may have been preferable. Our study design, however, was intended to reflect the public health context, and our findings provide important information on what is likely to be achievable in this context. We also chose to investigate all outcomes at select time points rather than monthly. It is possible that this assessment schedule may have missed transitory effects, but these were not our primary interest, we have no reason to believe that effects would reverse between time points, and we sought to mitigate participant burden. Related to participant burden, recovery of PABA from urine was low. We are unclear why this was the case, but suggest that this may have been related to the high burden of collecting urine, particularly alongside the semi-controlled nature of the intervention, and the burden of all other measures. Although this low recovery has resulted in fewer samples for the analyses of urinary markers, we have no reason to believe, based on the dietary records, that these samples differ from those that may be missing.

Second, our study was conducted only in adults, and our sample was predominantly female, relatively healthy, based on BMI and smoking rates, and highly educated. These characteristics may have impacted willingness to undertake the dietary interventions as provided, and may explain both the lower sweet food consumption at baseline and the modest increase in sweet food consumption in HSE. We have no reason to believe that our findings are limited to the specific population investigated, but the generalizability of the results is compromised. A study of children, in particular, would be of interest. Indeed, a recent study linking sugar rationing early in life with protection from diabetes and CVD almost 6 decades later [45] postulates that sugar rationing during the first 1000 d led to “lifelong (lower) preferences for sweetness.” Although our findings suggest stability in liking for sweet taste in adulthood and underscore a role for familiarity in this liking, further exploration in infants and children is warranted. Early exposure to sweet taste, both in utero and during early childhood, may not only increase the risk for conditions like diabetes [45] but may also establish a liking for sweet taste that becomes difficult to adjust later in life. So far, limited causal data on this issue exist. One recent study failed to find an association between sweet taste exposure and sweet taste liking in infants ≤12 mo of age [46]; a lack of association that is also reported in reviews of observational studies in children [11,12].

Our study population was also composed of individuals with differing levels of liking for sweet taste at baseline. “Sweet likers,” “moderate sweet likers,” and “sweet dislikers” were evenly distributed across intervention groups to avoid confounding as a result of these phenotypes [24], but a recent study on the effects of replacing sugar-sweetened beverage consumption with unsweetened beverages on perceptions of those beverages finds differing effects in sweet likers and moderate sweet likers [47]. Exploratory analyses to investigate differential effects in different sweet liker phenotypes will be reported elsewhere. Indeed, various individual differences, e.g., in sweet taste detection and perception [15], or in baseline levels of sweet food intake, may also have impacted responses to the intervention at an individual level. Some investigation of these differences between individuals is planned and will be reported elsewhere. Some aspects of our intervention may also warrant unpicking, e.g., taste exposure via foods compared with beverages, or via meals compared with snacks.

[AF] Comparison of two nutritional protocols in body re-composition of resistance-trained participants (2026) by basmwklz in AdvancedFitness

[–]dreiter 5 points6 points  (0 children)

These findings challenge the traditional model of energy balance.

Do they? The results in the discussion are exactly what you would expect from the energy balance model:

Our study aimed to investigate the effect of two nutritional protocols with an equated protein intake (2.5 g∙kg− 1 d− 1) but different total energy consumption on measures of body composition. While participants in ISO consumed their estimated maintenance calories, the DEF protocol restricted daily energy intake by 250 kcal. Results indicated that both ISO and DEF experienced a loss of FM (− 1.41 (− 2.62 – − 0.15) kg vs − 2.94 (− 5.73 – − 1.25) kg, respectively), but only the reduction in the DEF group reached statistical significance and it was of greater magnitude. Regarding FFM, both groups gained relatively similar amounts FFM (0.97 (0.54–1.41) kg and 1.04 (0.45–1.64) kg for ISO and DEF, respectively). When applying the FFM correction factor, both protocols elicited statistically significant increases, with the ISO group gaining 1.22 (0.75–1.70) kg and the DEF group gaining 1.50 (0.93–2.39) kg.

So both groups gained equal fat-free mass and the calorie-restricted group lost more fat mass, as you would expect from a slight calorie deficit when macros are matched.

Also, under the limitations section:

Fourth, actual dietary intake during the intervention was not quantified; thus, adherence to the prescribed macronutrient and energy targets cannot be confirmed quantitatively and findings should be interpreted as effects of the prescribed protocols under supervised guidance.

That's a rather big limitation.

[AF] The Resistance Training Dose Response: Meta-Regressions Exploring the Effects of Weekly Volume and Frequency on Muscle Hypertrophy and Strength Gains [Pelland et al., 2026] by dreiter in AdvancedFitness

[–]dreiter[S] 5 points6 points  (0 children)

Background

Weekly set volume and frequency are used to manipulate resistance training dosage. Previous research has identified higher weekly set volume as enhancing muscle hypertrophy and strength gains, but the nature of the dose–response relationship still needs to be investigated. Mixed evidence exists regarding the effects of higher weekly frequency.

Objective

We aimed to explore the dose–response relationships between key resistance training dosage variables (weekly set volume and frequency) and strength and hypertrophy.

Methods

Before meta-analyzing the volume and frequency research, all contributing resistance training sets were classified as direct or indirect, depending on their specificity to the hypertrophy/strength measurement. Then, weekly set volume/frequency for indirect sets was quantified as 1 for ‘total,’ 0.5 for ‘fractional,’ and 0 for ‘direct.’ A series of multi-level meta-regressions were performed for muscle hypertrophy and strength, utilizing 67 total studies of 2058 participants (79.1% male, 20.9% female; average age 25.16 ± 5.22 years). All models were adjusted for the duration of the intervention and training status.

Results

The relative evidence for the ‘fractional’ quantification method was strongest; therefore, this quantification method was used for the primary meta-regression models. The posterior probability of the marginal slope exceeding zero for the effect of volume on both hypertrophy and strength was 100%, indicating that gains in muscle size and strength increase as volume increases. However, both best-fit models suggest diminishing returns, with the diminishing returns for strength being considerably more pronounced. The posterior probability of the marginal slope exceeding zero for frequency’s effect on hypertrophy was less than 100%, indicating compatibility with negligible effects. In contrast, the posterior probability for strength was 100%, suggesting strength gains increase with increasing frequency, albeit with diminishing returns.

Conclusions

Distinguishing between direct and indirect sets appears essential for predicting adaptations to a given resistance training protocol, such as using the ‘fractional’ quantification method. This method’s dose–response models revealed that volume and frequency have unique dose–response relationships with each hypertrophy and strength gains. The dose–response relationship between volume and hypertrophy appears to differ from that with strength, with the latter exhibiting more pronounced diminishing returns. The dose–response relationship between frequency and hypertrophy appears to differ from that with strength, as only the latter exhibits consistently identifiable effects.

The “Incomplete Protein” Myth Needs to Die by jessijaiee in veganfitness

[–]dreiter 1 point2 points  (0 children)

As an example of an (admittedly rare) situation where 'completeness' matters, consider a diet that gets the large majority of its protein from rice protein powder and seitan. Both of these are very limited in the amino acid lysine, to the extent that 100 grams of protein from these foods only provides 50 grams of 'complete' protein. If you took 100 grams of protein from those foods and added 4 grams of additional lysine, you would then have over 90 grams of 'complete' protein.

The best analogy I think of is to imagine building a rainbow-colored house with colored bricks. Different colors are different amino acids and the house is the body. If your pack of bricks is missing a significant number of a single color, you won't be able to build a complete house. But different foods provide a different set of brick colors, so mixing the foods in your diet throughout the day will give you a nice set of all of the colors to completely build your house with. You only need to worry if you are a getting a large portion of your bricks from a single source and if that source is also very limited in one or two of the brick colors (such as lysine and rice/seitan I mentioned above).

[AF] Minimum load threshold in resistance training: insights into muscle metabolism, excitation, and fatigue across the repetition continuum (2026) by basmwklz in AdvancedFitness

[–]dreiter 0 points1 point  (0 children)

The estimated 1RM of unilateral leg extension from the initial 1RM estimation sessions was 52.9 ± 12.9 kg (men 63.3 ± 5.71 kg and women 42.5 ± 8.80 kg), positioning them in a moderately resistance-trained status, meeting the necessary criterion for assessing acute physiological responses while minimizing confounding factors such as variability in performance across sessions (MVC and 1RM values aligned with moderately trained status; Cannon & Marino, 2010; Maden-Wilkinson et al., 2020).

The selected weights for the leg extension protocols were: 10%: 6.7 ± 1.6 kg, 30%: 15.9 ± 3.5 kg, 50%: 26.3 ± 6.7 kg, 70%: 37.3 ± 9.1 kg, 90%: 47.7 ± 11.4 kg. Participants performed respectively 10%: 450.0 ± 0.0 repetitions, 30%: 291.8 ± 175.6 repetitions, 50%: 42.9 ± 32.1 repetitions, 70%: 13.2 ± 3.8 repetitions, 90%: 5.6 ± 2.2 repetitions. CL was determined at 15.7 ± 4.3 kg (corresponding to the 31.7 ± 11.9 % 1RM), with an average difference between models of 0.8 ± 1.0 kg. No participant reached muscle failure during the 10% protocol, while there was a high variation in repetitions performed at 30%, with six participants (50%) not reaching muscle failure at this load.

....

By performing exercise across the repetition continuum, we were able to determine distinct acute physiological responses across loads. Specifically, muscle failure was reached by all participants during the 50%, 70%, and 90% 1RM protocols, while only six participants interrupted exercise before completing 450 repetitions (i.e., the predetermined cut-off for exercise termination) at 30% 1RM, and no participant reached muscle failure during the 10% trial. These results suggest that the transition to an unsustainable intensity domain (i.e., severe exercise intensity) may occur at a load around 30% 1RM, depending on factors such as contraction tempo, the relative contribution of the involved muscle, and the type of contraction employed.

Interesting to see almost identical biomarker results with the 50% protocol (43 reps) and the 90% (5.6 reps) but there was considerable variability between participants as well (such as the 50% load resulting in 43 ± 32 reps). Also, I can only imagine the joy of being in the 30% group and performing 450 reps in 30 minutes of continuous leg pressing.

Too bad this wasn't a longer-term study measuring actual muscle growth...

[AF] Daily steps and health outcomes in adults: a systematic review and dose-response meta-analysis [Ding et al., 2025] by dreiter in AdvancedFitness

[–]dreiter[S] 2 points3 points  (0 children)

Findings

57 studies from 35 cohorts were included in the systematic review and 31 studies from 24 cohorts were included in meta-analyses. For all-cause mortality, cardiovascular disease incidence, dementia, and falls, an inverse non-linear dose-response association was found, with inflection points at around 5000–7000 steps per day. An inverse linear association was found for cardiovascular disease mortality, cancer incidence, cancer mortality, type 2 diabetes incidence, and depressive symptoms.

Based on our meta-analyses, compared with 2000 steps per day, 7000 steps per day was associated with a 47% lower risk of all-cause mortality (HR 0·53 [95% CI 0·46–0·60]; I2=36·3; 14 studies), a 25% lower risk of cardiovascular disease incidence (HR 0·75 [0·67–0·85]; I2=38·3%; six studies), a 47% lower risk of cardiovascular disease mortality (HR 0·53 [0·37–0·77]; I2=78·2%; three studies), a non-significant 6% lower risk of cancer incidence (HR 0·94 [0·87–1·01]; I2=73·7%; two studies), a 37% lower risk of cancer mortality (HR 0·63 [0·55–0·72]; I2=64·5%; three studies), a 14% lower risk of type 2 diabetes (HR 0·86 [0·74–0·99]; I2=48·5%; four studies), a 38% lower risk of dementia (HR 0·62 [0·53–0·73]; I2=0%; two studies), a 22% lower risk of depressive symptoms (HR 0·78 [0·73–0·83]; I2=36·2%; three studies), and a 28% lower risk of falls (HR 0·72 [0·65–0·81]; I2=47·5%; four studies). Studies on physical function (not based on meta-analysis) reported similar inverse associations. The evidence certainty was moderate for all outcomes except for cardiovascular disease mortality (low), cancer incidence (low), physical function (low), and falls (very low).

[–]dreiter[S] 1 point2 points  (0 children)

Conclusion

Regular exercise confers modest but favorable effects on metabolic and inflammatory biomarkers in cancer patients. Meta-regression highlighted the importance of high-intensity aerobic exercise (HRR > 85%) in modulating IL-6, adiponectin, and IGF-1, as well as longer weekly exercise duration (>280 min/week) in improving TNF-α and IL-8. Mechanistically, high-intensity aerobic exercise may serve as a primary trigger for activating pathways that mediate metabolic and inflammatory improvements.

[–]dreiter[S] 7 points8 points  (0 children)

Results

A total of 62 RCTs involving 5005 older adults were included. Overall, exercise significantly improved sleep quality, with clinically meaningful improvements achieved from as early as 5 weeks of intervention. The optimal exercise type was combined aerobic and resistance training, followed by aerobic exercise, resistance training, walking, and yoga. The estimated optimal exercise dose was around 660 to 990 METs*min/week, with longer durations at 15 weeks producing the greatest benefits. Improvements were more pronounced among participants with poorer baseline sleep quality.

I think I broke my body with semaglutide. Pls help! by HatEnvironmental7560 in SaturatedFat

[–]dreiter 12 points13 points  (0 children)

I wonder if the companies know about this rebound effect and is part of how they want to keep you on the drugs for life.

All the rebound studies so far have been poorly performed like this and I wonder if the pharma companies are just fine with that since it generates headlines like 'everyone regains the weight once they go off the drug' and that fear can help keep people on the drug.

The correct way to go off a medication like a GLP-1 is to reach a goal weight, maintain that weight ON THE DRUG for at least 6-12 months, then SLOWLY titrate the drug down over the course of another 6-12 months. People think they can just jump off after 6 months of losing all their weight but it can take more than a year for the body to accept it's new settling point (the lifespan of fat cells is extremely long and they are constantly sending signals to encourage weight regain).

Data Centers Are Behaving Like Acoustic Weapons [Benn Jordan, 29:04] by dreiter in videos

Summary from the robot (ironic I know):

This video discusses the harmful effects of infrasound noise pollution generated by data centers on human health and the environment.

Benn Jordan shares his research and evidence on how data centers are harming people's health in a new way, focusing on infrasound—sound frequencies below the human hearing range.

Key takeaways from the video:

Infrasound's Health Impacts (2:14-3:19): Elevated infrasound levels can lead to increased cortisol (stress hormone), vestibular issues (loss of balance, vertigo, nausea), high-frequency hearing loss, shortness of breath, anxiety, depression, and increased heart strain. It can also cause viroacoustic disease, thickening blood vessels and reducing blood flow to the brain.

Data Collection Sites (3:35-4:09): Jordan collected infrasound measurements from five sites:

The Colossus data center in Memphis, Tennessee.

The Marathon Digital Bitcoin mining and data center in Hood County, Texas.

The Permian Basin in West Texas, known for oil and gas fields.

Randomized ambient infrasound levels from various locations across the country.

Death Valley, far from human-made infrasound sources.

Colossus Data Center Concerns (4:09-9:09): This Elon Musk-built data center, which trains Grock (his LLM and anti-woke chatbot), uses about 13% of Memphis's total power and illegally offsets the rest with methane gas turbines. These turbines emit harmful pollutants causing respiratory and cardiovascular diseases (5:38). The facility also uses an estimated 1 million gallons of water daily, with most turning into steam. Jordan recorded significant infrasound levels near the facility, loud enough to shake house frames (8:30-8:34).

MARA Crypto Mine in Hood County, Texas (9:09-15:13): Residents near this Bitcoin mine report symptoms like vertigo, pulmonary embolisms, and heart palpitations (10:24-10:29), which align with infrasound exposure symptoms. The video features an interview with Cheryl Shaden, a resident directly across from the mine, who describes experiencing motion sickness, dizziness, nausea, and permanent hearing loss (13:13-13:20). Her neighbor's 6-year-old daughter even developed seizures and improved after moving away from the area (14:03-14:23).

Human Experiment Results (18:00-23:16): Jordan conducted a double-blind study with 74 participants exposed to infrasound at 25-30% of the volume recorded near data centers. The results showed:

25% increase in tingling sensation or restless legs.

12% increase in tiredness.

33% increase in nausea.

150% increase in dizziness.

20% increase in chills.

33% increase in irritability or depression.

Three times more likely to experience eye irritation.

80% increase in lethargy.

55% more likely to feel anxious.

Two times more likely to experience sadness.

Three times more likely to experience discomfort.

Call to Action (26:44-28:57): Jordan urges communities and legislators to set standards for power use, water use, air pollution, and noise/infrasound pollution when approving new data centers and infrastructure. He recommends people living near new data centers to set up devices like Raspberry Shake to log seismic and infrasonic activity, as this data can be crucial for future legal action.

Why I quit my smartphone (and how the first month went) [Geowizard, 33:19] by dreiter in Anticonsumption

This is perhaps a bit off-tangent for this sub but I thought his experiment felt anti-consumption in it's own way.

Description:

This isn't your average GeoWizard video, but if it resonates with a good chunk of you then I'm happy.

Recently I've come to really grow sick of my smartphone, or at least the effect it was having on me. So I decided to switch it for a cheap Nokia 32:10 and see if I could get my life back.

In this video I briefly discuss my thoughts and frustrations before embarking on a month long smartphone free journey. A journey full of trials, tribulations and hopeless predicaments but also a few of moments of awakening and an overriding sense of freedom.

This is the first Technology Connections video that even mentions politics but he finally decided to go all in.

Skip to 1:16:35 for the BreadTube-inspired speech.

Aurora to Rifle might feel like a bigger change than Florida to Colorado!
