  • BMI is the sum of FFMI+FMI
  • FMI were significantly higher in elderly subjects as compared to younger ones
  • During menopause and aging39,40 changes in FFM and FM are not adequately picked up by changes in BMI
  • ...8 more annotations...
  • One advantage of FMI, as compared to the BMI concept, is that it amplifies the relative effect of aging on body fat
  • We believe that the definition of obesity based on relative body fat (ie percentage) remains of great value for the definition of obesity. However, in a situation in which a patient is losing weight without substantially changing his/her relative body fat (as is the case with crash diets), the calculation of FMI will quantitatively reveal the amount of body fat store lost.
  • high sensitivity of FMI (respectively FFMI) to a slight change of body fat stores
  • Sarcopenic obesity has been defined as a low FFM associated with a high body fat
  • relative FFM lower than 73% (ie a relative body fat greater than 27%) in men and a FFM lower than 62% (ie a body fat greater than 38%) in women.
  • FMIs greater than 8.2 kg/m2 in men and 11.8 kg/m2 in women would define the 'overfat' status (rather than the overweight range) in terms of fat mass
  • In young women, FMI averaged 5.5 kg/m2 (range 5th-95th percentile: 3.5-8.7 kg/m2) ie 38% higher than in males
  • the average FMI for young men was 4.0 kg/m2

    Nice review of the mixed data on Testosterone and Prostate disease. It is clear that Testosterone does not precipitate prostate cancer.  The intraprostatic hormone milieu likely is different than that present in the serum.  No surprise there.  5alpha reductase decreases prostate volume, PSA, and low-grade prostate cancer, but actually increases aggressive prostate cancer. Supraphysiologic doping in young men associated with no increase in prostate disease. PSA no longer to be followed in men < 55.  Mortality rate not changed.  PSA change of 1.4 ng/ml is appropriate for additional prostate evaluation.  Testosterone therapy on average increased 0.5 ng/ml. Still, no mention of aromatase activity in this article.  Why is it that hormone sensitive disease in men is only with regards to androgens and women estrogen.

  • The microbiota of the large intestine plays an important role in host metabolism and maintenance of host health
  • Our results defining a standard adult profile, together with previous reports, showed that C. leptum, C. coccoides, Bacteroides and Bifidobacterium represent the four dominant groups of the adult fecal microbiota
  • Sub-dominant groups are Lactobacilli Enterobacteriaceae, Desulfovibrio, Sporomusa, Atopobium as well as other bacterial groups including Clostridium clusters XI, XIVb, and XVIII
  • ...12 more annotations...
  • In infant fecal microbiota, we observed Bifidobacterium as the dominant group
  • this observation is strongly related to diet, being enhanced by breast feeding
  • Significant higher numbers of Bifidobacterium were observed in infants versus adults and seniors
  • the gastrointestinal tract is first colonized by facultative anaerobes, such as E. coli
  • Strict anaerobes, such as Clostridium, colonize at later stages, as can be seen by the relatively low levels of C. leptum and C. coccoides in infants
  • diet change must be considered among the primary causes for such a shift of microbiota between infants and adults.
  • In the case of elderly subjects, our qPCR results indicated a significant increase in the counts of E. coli when compared to adults. This data is consistent with other publications indicating that elderly subjects harbor a different E. coli microbiota profile compared to younger adults
  • a number of authors reported a reduction in the numbers and diversity of many protective commensal anaerobes, such as Bacteroides and Bifidobacteria
  • The Firmicutes to Bacteroidetes ratio was already shown to be of significant relevance in signaling human gut microbiota status
  • Our measurements of the Firmicutes/Bacteroidetes ratio in adults obtained by our species-specific qPCR are in agreement with those obtained by Ley et al
  • Compared with young adults, the elderly have a different digestive physiology, characterized at a physiological level by a reduction in transit and of digestive secretions
  • The Firmicutes/Bacteroidetes ratio undergoes an increase from birth to adulthood and is further altered with advanced age
  • Nathan Goodyear on 06 May 15
     
    Good discussion of the gut microbiome.  Age effects the gut bacteria balance.  The Firmicutes/Bacteroidetes ratio increases from young, to young adult, to the elderly in this study.  Is this simply a reflection of aging or is the a biomarker that can be changed through diet and targeted probiotics?

shared by Nathan Goodyear on 27 Jul 14 - No Cached
  • The gut microbiota participates in the body’s metabolism by affecting energy balance, glucose metabolism, and low-grade inflammation associated with obesity and related metabolic disorders
  • Firmicutes and Bacteroidetes represent the two largest phyla in the human and mouse microbiota and a shift in the ratio of these phyla has been associated with many disease conditions, including obesity
  • In obese humans, there is decreased abundance of Bacteroidetes compared to lean individuals
  • ...21 more annotations...
  • weight loss in obese individuals results in an increase in the abundance of Bacteroidetes
  • there is conflicting evidence on the composition of the obese microbiota phenotype with regards to Bacteroidetes and Firmicutes ratios
  • Bifidobacteria spp. from the phyla Actinobacteria, has been shown to be depleted in both obese mice and human subjects
  • While it is not yet clear which specific microbes are inducing or preventing obesity, evidence suggests that the microbiota is a factor.
  • targeted manipulation of the microbiota results in divergent metabolic outcomes depending on the composition of the diet
  • The microbiota has been linked to insulin resistance or type 2 diabetes (T2D) via metabolic syndrome and indeed the microbiota of individuals with T2D is also characterized by an increased Bacteroidetes/Firmicutes ratio, as well as an increase in Bacillus and Lactobacillus spp
  • It was also observed that the ratio of Bacteriodes-Prevotella to C. coccoides-E. rectale positively correlated with glucose levels but did not correlate with body mass index [80]. This suggests that the microbiota may influence T2D in conjunction with or independently of obesity
  • In humans, high-fat Western-style diets fed to individuals over one month can induce a 71% increase in plasma levels of endotoxins, suggesting that endotoxemia may develop in individuals with GI barrier dyfunction connected to dysbiosis
  • LPS increases macrophage infiltration essential for systemic inflammation preceding insulin resistance, LPS alone does not impair glucose metabolism
  • early treatment of dysbiosis may slow down or prevent the epidemic of metabolic diseases and hence the corresponding lethal cardiovascular consequences
  • increased Firmicutes and decreased Bacteroidetes, which is the microbial profile found in lean phenotypes, along with an increase in Bifidobacteria spp. and Lactobacillus spp
  • mouse and rat models of T1D have been shown to have microbiota marked by decreased diversity and decreased Lactobacillus spp., as well as a decrease in the Firmicutes/Bacteroidetes ratio
  • microbial antigens through the innate immune system are involved in T1D progression
  • The microbiota appears to be essential in maintaining the Th17/Treg cell balance in intestinal tissues, mesenteric and pancreatic lymph nodes, and in developing insulitis, although progression to overt diabetes has not been shown to be controlled by the microbiota
  • There is evidence that dietary and microbial antigens independently influence T1D
  • Lactobacillus johnsonii N6.2 protects BB-rats from T1D by mediating intestinal barrier function and inflammation [101,102] and a combination probiotic VSL#3 has been shown to attenuate insulitis and diabetes in NOD mice
  • breast fed infants have higher levels of Bifidobacteria spp. while formula fed infants have higher levels of Bacteroides spp., as well as increased Clostridium coccoides and Lactobacillus spp
  • the composition of the gut microbiota strongly correlates with diet
  • In mice fed a diet high in fat, there are many key gut population changes, such as the absence of gut barrier-protecting Bifidobacteria spp
  • diet has a dominating role in shaping gut microbiota and changing key populations may transform healthy gut microbiota into a disease-inducing entity
  • “Western” diet, which is high in sugar and fat, causes dysbiosis which affects both host GI tract metabolism and immune homeostasis

    Breast cancer survivors (BCS) exhibit decreased physical function and quality of life (QOL) following cancer treatments. Resistance training (RT) may elicit positive changes in physical and mental well-being. This study assessed 27 BCS, pre-and post-intervention (six months) on the following variables: muscular strength (via one repetition maximum (1RM) of chest press and leg extension), physical function (via the Continuous Scale-Physical Functional Performance test) and QOL (via the Short Form-36 survey). RT consisted of two days/week of ten exercises including two sets of 8-12 repetitions at 52%-69% of their 1RM. A repeated measures analysis of variance revealed BCS significantly (p &lt; 0.05) increased upper (71 ± 22 to 89 ± 22 kg) and lower body (74 ± 18 to 93 ± 24 kg) strength, total physical function (65.5 ± 12.1 to 73.6 ± 12.2 units) and the subcomponents of physical function: upper body strength (63.5 ± 16.3 to 71.2 ± 16.8 units), lower body strength (58.5 ± 14.9 to 68.6 ± 16.3 units), balance and coordination (66.5 ± 12.2 to 74.6 ± 11.6 units), and endurance (67.2 ± 12.0 to 75.0 ± 11.6 units). No changes were observed over time for subjective measures of physical function and QOL. Results showed RT could be an effective means to improve objective physical function in BCS. Further research is needed to clarify the effects of RT on subjective physical function and QOL.

shared by Nathan Goodyear on 10 Apr 21 - No Cached
  • steroid hormones typically interact with their cognate receptor in the cytoplasm for AR, glucocorticoid receptor (GR) and PR, but may also bind receptor in the nucleus as appears to often be the case for ERα and ERβ
  • This ligand binding results in a conformational change in the cytoplasmic NRs that leads to the dissociation of HSPs, translocation of the ligand-bound receptor to the nucleus
  • In the nucleus, the ligand-bound receptor dimerizes and then binds to DNA at specific HREs to regulate gene transcription
  • ...25 more annotations...
  • some steroid hormone-induced nuclear events can occur in minutes
  • the genomic effects of steroid hormones take longer, with changes in gene expression occurring on the timescale of hours
  • Classical steroid hormone signaling occurs when hormone binds nuclear receptors (NR) in the cytoplasm, setting off a chain of genomic events that results in, among other changes, dimerization and translocation to the nucleus where the ligand-bound receptor forms a complex with coregulators to modulate gene transcription through direct interactions with a hormone response element (HRE)
  • NRs have been found at the plasma membrane of cells, where they can propagate signal transduction often through kinase pathways
  • Membrane-localized ER, PR and AR have been reported to modulate the activity of MAPK/ERK, phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt), nitric oxide (NO), PKC, calcium flux and increase inositol triphosphate (IP3) levels to promote cell processes including autophagy, proliferation, apoptosis, survival, differentiation, and vasodilation
  • ERα36, a 36kDa truncated form of ERα that lacks the transcriptional activation domains of the full-length protein. Membrane-localized ERα36 can activate pathways including protein kinase C (PKC) and/or mitogen activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) to promote the progression of various cancers
  • G protein-coupled receptor 30 (GPR30), also referred to as G protein-coupled estrogen receptor (GPER), is a membrane-localized receptor that has been observed to respond to estrogen to activate rapid signaling
  • hormone-responsive G protein coupled receptor is Zip9, which androgens can activate
  • GPRC6A is another G protein-coupled membrane receptor that is responsive to androgen
  • androgen-mediated non-genomic signaling through this GPCR can modulate male fertility, hormone secretion and prostate cancer progression
  • non-NR proteins located at the cell surface can bind to steroid hormones and respond by eliciting rapid signaling events
  • Estrogens have been shown to induce rapid (i.e. seconds) calcium flux via membrane-localized ER (mER)
  • ER-calcium dynamics lead to activation of kinase pathways such as MAPK/ERK which can result in cellular effects like migration and proliferation
  • 17β-estradiol (E2) has been reported to promote angiogenesis through the activation of GPER
  • Membrane NRs may also mediate rapid signaling through crosstalk with growth factor receptors (GFR)
  • A similar crosstalk occurs between the receptor tyrosine kinase insulin-related growth factor-1 receptor (IGF-IR) and ERα. Not only does IGF-IR activate ERα, but inhibition of IGF-IR downregulates estrogen-mediated ERα activity, suggesting that IGF-IR is essential for maximal ERα signaling

      This is a bombshell that shatters the current right brain approach to ER. It completely shatters the concept of eat sugar, whatever you want, with cancer treatment in ER+ or hormonally responsive cancer!
  • Further, ER activates IGF-IR pathways including MAPK
  • GPER is involved in the transactivation of the EGFR independent of classical ER
  • tight interconnection between genomic and non-genomic effects of NRs.
  • non-genomic pathways can also lead to genomic effects
  • androgen-bound AR associates with the kinase Src at the plasma membrane, activating Src which then leads to a signaling cascade through MAPK/ERK
  • However, Src can also increase the expression of AR target genes by the ligand-independent transactivation of AR
  • extranuclear steroid hormone actions can potentially reprogram nuclear NR events
  • estrogen modulated the expression of several genes including endothelial nitric oxide synthase (eNOS) via rapid signaling pathways
  • epigenetic changes can then mediate genomic events in uterine tissue and breast cancer cells

    The Pharmacists' Defence Association (PDA) has expressed concerns over Boots UK's decision to reduce supplemental opening hours at some pharmacies. The association stated: "Some pharmacists and other staff at Boots are being notified this week of changes to opening hours at their place of work, with local briefings taking place. The PDA are supporting their members to deal with any potential impact on their employment." It said that reducing pharmacy opening hours would affect patients' access to a trusted healthcare professional, especially if it is being done by the largest community pharmacy multiple. It even called upon the NHS to adequately fund community pharmacies to ensure they remain open when patients and local communities need their services. Meanwhile, Boots management has informed PDA that most of its employees are not pharmacists, and "less pharmacists are expected to be directly impacted by these changes than other colleagues," PDA said.
