Nitrogen ‐Containing Bisphosphonates Are Associated With Reduced Risk of Pneumonia in Patients With Hip Fracture

The objective of this work was to study the risk of pneumonia and pneumonia mortality among patients receiving nitrogen ‐containing bisphosphonates (N‐BPs), non‐N‐BP anti‐osteoporosis medications, and no anti‐osteoporosis medications after hip fracture. We studied a historical cohort using a population‐wide database. Patients with first hip fracture during 2005–2015 were identified and matched by time ‐dependent propensity score. The cohort was followed until December 31, 2016, to capture any pneumonia and pneumonia mortality. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox‐proportional hazards regression. Absolute risk difference (ARD) and number needed to tre at (NNT) were calculated. We identified 54,047 patients with hip fracture. Of these, 4041 patients who received N‐BPs and 11,802 without anti‐osteoporosis medication were propensity score–matched. N‐BPs were associated with a significantly lower risk of pneumonia compared with no treatment ( 6.9 versus 9.0 per 100 person‐years; HR 0.76; 95% CI, 0.70 to 0.83), resulting in an ARD of 0.02 and NNT of 46. A similar association was observed with pneumonia mortality (HR 0.65; 95% CI, 0.56 to 0.75). When N‐BPs were compared with non‐N‐BP anti‐osteoporosis medications, the association remained significant. N‐BPs were associated with lower risks of pneumonia and pneumonia mortality. Randomized controlled trials are now required to determine whether ...

In conclusion, our results suggest a previously unknown mechanism whereby the canonical NF-κB cascade and a mitochondrial fission pathway interdependently regulate endothelial inflammation. Lin28 as a Target for Nerve Regeneration https://www.fightaging.org/archives/2020/05/lin28-as-a-target-for-nerve-regeneration/ Researchers here show that the gene Lin28 regulates axon regrowth. In mice, raised levels of Lin28 produce greater regeneration of nerve injuries. Past research has investigated Lin28 from the standpoint of producing a more general improvement in regenerative capacity. It improves mitoch...

This study provides direct evidence for the contribution of gut microbiota to the cognitive decline during normal aging and suggests that restoring microbiota homeostasis in the elderly may improve cognitive function. On Nutraceutical Senolytics https://www.fightaging.org/archives/2020/05/on-nutraceutical-senolytics/ Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therape...

In this study, we hypothesized that moderately and chronically reducing ACh could attenuate the deleterious effects of aging on NMJs and skeletal muscles. To test this hypothesis, we analyzed NMJs and muscle fibers from heterozygous transgenic mice with reduced expression of the vesicular ACh transporter (VAChT), VKDHet mice, which present with approximately 30% less synaptic ACh compared to control mice. Because ACh is constitutively decreased in VKDHet, we first analyzed developing NMJs and muscle fibers. We found no obvious morphological or molecular differences between NMJs and muscle fibers of VKDHet and contro...

James Peyer, formerly of Apollo Ventures and now at the larger Kronos BioVentures, has a range of interesting views on the new and growing longevity biotechnology industry. Apollo Ventures was one of the earlier longevity-focused funds to emerge from the comparatively small community of scientists, patient advocates, and investors enthusiastic to accelerate progress towards the treatment of aging as a medical condition. The presentation here was given earlier this year at the Ending Age-Related Diseases conference organized by the Life Extension Advocacy Foundation. In the matter of creating new medical therapies, t...

LITFL • Life in the Fast Lane Medical Blog LITFL • Life in the Fast Lane Medical Blog - Emergency medicine and critical care medical education blog aka Tropical Travel Trouble 009 The diagnosis of HIV is no longer fatal and the term AIDS is becoming less frequent. In many countries, people with HIV are living longer than those with diabetes. This post will hopefully teach the basics of a complex disease and demystify some of the potential diseases you need to consider in those who are severely immunosuppressed. While trying to be comprehensive this post can not be exhaustive (as you can imagine any patient with ...

AbstractPurpose of ReviewPatients with inflammatory bowel disease (IBD) are not receiving preventative care services at the same rate as the general population. IBD patients are at increased risk for infections, osteoporosis, and certain malignancies secondary to their disease and as they are on immunosuppressive therapy. They are a younger population and often times consider their gastroenterologist as their primary care physician. In this review, we discuss up-to-date evidence pertaining to vaccine-preventable illnesses in the immunosuppressed IBD patient, screening for bone health, cervical cancer, skin malignancies, ps...

We examined associations between mortality and accelerometer-measured PA using age-relevant intensity cutpoints in older women of various ethnicities. The results support the hypothesis that higher levels of accelerometer-measured PA, even when below the moderate-intensity threshold recommended in current guidelines, are associated with lower all-cause and CVD mortality in women aged 63 to 99. Our findings expand on previous studies showing that higher self-reported PA reduces mortality in adults aged 60 and older, specifically in older women, and at less than recommended amounts. Moreover, our findings challenge th...

My attention was drawn today to a recently published presentation by James Peyer. He heads up Apollo Ventures, one of the new crop of investment concerns focused on funding companies that are developing means to treat aging. These include the Longevity Fund, first out of the gate some years ago, as well as Juvenescence and the Methuselah Fund, created this year, and a repurposing of existing funds, such as Michael Greve's Kizoo ventures. Apollo Ventures is the source of the Geroscience online magazine that helps to advance and explain the position taken on aging by this group; this is something that more investors should d...

Introduction The muscular dystrophies (MD) are a group of genetically heterogeneous muscle diseases marked by progressive wasting and weakness of the skeletal and cardiac muscles1. Duchenne muscular dystrophy (DMD) is the most common and most severe form. It is an X-linked disorder affecting 1 in 5000 live male births2,3. DMD is caused by mutations in the DMD gene, which encodes the muscle fiber membrane protein dystrophin. Deficiency or complete absence of dystrophin makes muscle fibers sensitive to damage upon contraction, leading to plasma membrane leakage and muscle fiber degeneration, which eventually leads to progres...
