Fight Aging! Newsletter, December 31st 2018

In conclusion, there are many anti-aging strategies in development, some of which have shown considerable promise for slowing down aging or delaying the onset of age-related diseases. From multiple pre-clinical studies, it appears that upregulation of autophagy through autophagy enhancers, elimination of senescent cells using senolytics, transfusion of plasma from young blood, neurogenesis and BDNF enhancement through specific drugs are promising approaches to sustain normal health during aging and also to postpone age-related diseases. However, these approaches will require critical assessment in clinical trials to determine their long-term efficacy and lack of adverse effects on the function of various tissues and organs. Evidence for a Human Late Life Mortality Plateau is an Illusion Arising from Bad Data https://www.fightaging.org/archives/2018/12/evidence-for-a-human-late-life-mortality-plateau-is-an-illusion-arising-from-bad-data/ Mortality rises with age. In fact the very definition of aging is that it is a rise in mortality rate due to intrinsic causes, the accumulation of unrepaired damage and subsequent systems failure. Some years ago it was quite robustly established that, after a certain point, aged flies stop aging in this sense. Their mortality rates remain at a very high plateau, and do not further increase over time. Since then, researchers have crunched the numbers and debated back and forth over whether or not human demographic data show...

Authors: Pennisi PA, Fernández MC, Martin A Abstract Pheochromocytomas/paragangliomas (PCCs/PGLs) are rare neuroendocrine tumors, developed from chromaffin cells derived from the neural crest. From a genetic point of view PCCs/PGLs are divided as sporadic cases, and inherited cases as part of hereditary (familial) syndromes. While the majority is benign, up to 26% of PCCs/PGLs will undergo malignant transformation. Validated prognostic pathological parameters for malignant PCCs/PGLs are still lacking. Signaling that follows the interactions between IGFs and their receptor/s in tumor cells received extensive ...

Authors: Hampe CS, Polgreen LE, Lund TC, McIvor RS Abstract Mucopolysaccharidosis type I (MPS I) is a rare autosomal recessive disorder, caused by deficiency of α-L-iduronidase, and consequent accumulation of dermatan and heparan sulfates. Severity of the disease ranges from mild (Scheie) to moderate (Hurler-Scheie) to severe (Hurler or MPS-IH). A prominent clinical manifestation of MPS-IH is dysostosis multiplex, a constellation of skeletal abnormalities. We performed a retrospective review comparing manifestations of dysostosis multiplex in patients presenting with MPSIH and relevant animal models. Dog, cat...

Authors: Silva MAFS, Dechichi P, Limirio PHJO Abstract Childhood obesity is a considerable worldwide health problem and a major risk factor for several chronic diseases. Fat rich diets result in altered serum levels of lipids, cytokines and hormonal factors, which influence skeletal acquisition and promote microstructural and mechanical behavior changes in bone, especially to bone quality and quantity. However, the possible longterm implications of high-fat diets in childhood are controversial. Despite not fully understood, multiple signaling pathways which support bone tissue homeostasis are altered under hyperlip...

Authors: Scheffer-Rath ME, Boot AM Abstract Vitamin D is important for skeletal growth, bone mineralization and dental health. Vitamin D deficiency is reported in many countries, may have several causes and can cause rickets in children. A guideline with recommendations of vitamin D supplementation to prevent nutritional rickets was published recently. The vitamin D receptor is present in many cells of the body including cells of the immune system. Many studies have been published on associations between vitamin D deficiency and extra skeletal effects, mainly without proof of causality in intervention studies. This...

ConclusionsNo difference between the LSTR and pulpectomy approaches could be confirmed by meta-analyses. The quality of evidence according to the GRADE scheme ranged from moderate to very low.Clinical relevanceThe present meta-analyses could not demonstrate the superiority of one treatment over the other.

Conclusions: There were significant differences with respect to clinical characteristics and comorbidity prevalence according to metformin use among Korean type 2 diabetes patients. Long-term follow-up of these patients is necessary to observe how this difference will affect clinical outcomes for these patients. PMID: 32774367 [PubMed]

Authors: Plunk EC, Richards SM Abstract The epigenome of an individual can be altered by endogenous hormones, environment, age, diet, and exposure to endocrine disrupting chemicals (EDCs), and the effects of these modifications can be seen across generations. Epigenetic modifications to the genome can alter the phenotype of the individual without altering the DNA sequence itself. Epigenetic modifications include DNA methylation, histone modification, and aberrant microRNA (miRNA) expression; they begin during germ cell development and embryogenesis and continue until death. Hormone modulation occurs during the agei...

The association between preoperative vitamin D deficiency (VDD) and the development of more severe postoperative hypocalcemia is still unclear. Objectives.
