Takahashi A. Zinc Supplementation Enhances the Hematopoietic Activity of Erythropoiesis-Stimulating Agents but Not Hypoxia-Inducible Factor-Prolyl Hydroxylase Inhibitors. Nutrients 2024; 16:520. [PMID: 38398842 PMCID: PMC10893400 DOI: 10.3390/nu16040520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 02/07/2024] [Accepted: 02/12/2024] [Indexed: 02/25/2024] Open
Abstract
Since zinc is involved in many aspects of the hematopoietic process, zinc supplementation can reduce erythropoiesis-stimulating agents (ESAs) in patients undergoing hemodialysis. However, it remains unclear whether hypoxia-inducible factor-prolyl hydroxylase inhibitors (HIF-PHIs) have similar reduction effects. HIF-PHI stabilizes HIF, which promotes hematopoiesis, although HIF-1α levels are downregulated by zinc. This study aimed to investigate the effect of zinc supplementation on the hematopoietic effect of HIF-PHI in patients undergoing hemodialysis. Thirty patients undergoing maintenance hemodialysis who underwent periods of treatment with roxadustat or darbepoetin alfa during the past 3 years were retrospectively observed. Participants who underwent periods with and without zinc supplementation were selected, with nine treated with darbepoetin alfa and nine treated with roxadustat. Similarly to the ESA responsiveness index (ERI), the hematopoietic effect of zinc supplementation was determined by the HIF-PHI responsiveness index (HRI), which was calculated by dividing the HIF-PHI dose (mg/week) by the patient's dry weight (kg) and hemoglobin level (g/L). Zinc supplementation significantly increased ERI (p < 0.05), but no significant change was observed (p = 0.931) in HRI. Although zinc supplementation did not significantly affect HRI, adequate zinc supplementation is required to alleviate concerns such as vascular calcification and increased serum copper during the use of HIF-PHI.

Abstract
AbstractBackgroundNumerous neuropsychiatric symptoms, including affective symptoms, chronic fatigue syndrome, and fibromyalgia symptoms, are present in patients with end-stage renal disease (ESRD). This study examines the relationship between neuropsychiatric symptoms and red blood cell (RBC) parameters, kidney function tests, zinc, C-reactive protein, and calcium levels in patients with ESRD.MethodsThe above biomarkers and the Beck-Depression Inventory, the Hamilton Anxiety Rating Scale, and the Fibro-Fatigue Rating Scale were measured in 70 patients with end-stage renal disease (ESRD) and 46 healthy controls.ResultsIncreased scores of depressive, anxious, cognitive, and physiosomatic symptoms (including chronic fatigue, fibromyalgia, and autonomous symptoms) characterise ESRD. One latent vector could be extracted from these diverse symptom domains, which are, therefore, manifestations of a common core referred to as the physio-affective phenome. The combined effects of aberrations in red blood cells (RBC) (number of RBC, hematocrit, and haemoglobin), kidney function tests (glomerular filtration rate, ureum, creatinine, albumin, and total serum protein), C-reactive protein, zinc, and copper explained 85.0% of the variance in the physio-affective phenome. In addition, the effects of kidney function decline on the phenome were partially mediated by RBC aberrations and elevated copper, whereas the effects of dialysis frequency were entirely mediated by decreased zinc and elevated CRP.ConclusionsAffective (depression and anxiety), cognitive, and physiosomatic symptoms due to ESRD are interrelated manifestations of the physio-affective phenome, which is driven by (in descending order of importance) kidney dysfunctions, erythron deficits, inflammation, elevated copper, and decreased zinc.

Abstract
Both life span and health span are influenced by genetic, environmental and lifestyle factors. With the genetic influence on human life span estimated to be about 20–25%, epigenetic changes play an important role in modulating individual health status and aging. Thus, a main part of life expectance and healthy aging is determined by dietary habits and nutritional factors. Excessive or restricted food consumption have direct effects on health status. Moreover, some dietary interventions including a reduced intake of dietary calories without malnutrition, or a restriction of specific dietary component may promote health benefits and decrease the incidence of aging-related comorbidities, thus representing intriguing potential approaches to improve healthy aging. However, the relationship between nutrition, health and aging is still not fully understood as well as the mechanisms by which nutrients and nutritional status may affect health span and longevity in model organisms. The broad effect of different nutritional conditions on health span and longevity occurs through multiple mechanisms that involve evolutionary conserved nutrient-sensing pathways in tissues and organs. These pathways interacting each other include the evolutionary conserved key regulators mammalian target of rapamycin, AMP-activated protein kinase, insulin/insulin-like growth factor 1 pathway and sirtuins. In this review we provide a summary of the main molecular mechanisms by which different nutritional conditions, i.e., specific nutrient abundance or restriction, may affect health span and life span.

Abstract
This study aims to explore the single and joint effects of depression and malnutrition on the incidence of first fall onset in a Chinese community-dwelling elderly population. This cohort study consisted of 739 residents without a history of falls who were aged 60 years and older (mean age: 67.08 ± 5.79 years, female: 58.2%). Depression was defined with the Geriatric Depression Scale (GDS)-30; a score of ≥11 was considered to be depressed, while malnutrition was defined with the Mini Nutritional Assessment where a score <17 was defined as malnourished. Over a 2-year follow-up period, older adults who experienced at least one fall were allocated to the first fall onset group. The prevalence of baseline falls was 21.36%. During the 2-year follow-up, incidence of first fall onset was 13.13%. After adjusting for all confounders, depression alone (adjusted odds ratio [OR] = 3.545, 95% confidence interval [CI] = 1.318-9.535) and malnutrition alone (adjusted OR = 2.204, 95% CI = 1.183-4.108) were observed to be independent risk factors for first fall onset, while comorbidity of depression and malnutrition showed progressively increased risk of promoting first fall (adjusted OR = 8.161, 95% CI = 3.591-18.545) than those with only depression or malnutrition or without both depression and malnutrition. Malnutrition mediated 56% effects in the association between depression and first fall onset, while depression mediated 76% effects in the promoting role of malnutrition in first fall. Depression and malnutrition were found to be independent causes for promoting first fall, while mental health and nutrition should be treated as commonly prior interventions to delay first fall onset. Meanwhile, for malnourished Chinese community-dwelling older adults, avoidance or treatment of depression should be addressed at first.

Abstract
Aging is associated with a loss of sex hormone in both men (andropause) and women (menopause). In men, reductions in testosterone can trigger declines in muscle mass, bone mass, and in physical function. In women, the impact of the loss of sex hormones, such as estradiol, on bone is well elucidated, but evidence is limited on whether the loss of estradiol negatively affects muscle mass and physical function. However, deficiencies in multiple anabolic hormones have been shown to predict health status and longevity in older persons. Thus, consideration should be given as to whether targeted hormone replacement therapies may prove effective at treating clinical conditions, such as age-related sarcopenia, cancer cachexia, and/or acute or chronic illnesses. If initiated carefully in the appropriate clinical population, hormone replacement therapies in men and women may prevent and reverse muscle and bone loss and functional declines and perhaps promote healthy aging and longevity.

Abstract
Deficiency of zinc plays an important role in the pathogenesis of osteoporosis; however, the underlying mechanism is not well understood. Apoptosis of osteoblast causing the loss of bone mass is an important event in the osteoporosis. In this article, we investigated whether zinc deficiency would induce cell apoptosis in MC3T3-E1 cells and ask if it is involved in mitochondrial-mediated pathway. Significant increased apoptosis were observed in zinc deficiency group (ZnD: 5 μM TPEN and 1 μM zinc) compared with untreated control or zinc adequacy group (ZnA: 5 μM TPEN and 15 μM zinc). The mitochondrial membrane potential was strikingly reduced in ZnD group. Furthermore, we observed that the levels of Bax in mitochondria fraction and cyto c, AIF, and cleaved caspase-3/-9 in cytosol fraction were increased in ZnD group. We proposed that zinc deficiency would induce the translocation of Bax into mitochondria, which could lead to the reduction in mitochondrial membrane potential as well as the increase in mitochondrial membrane permeability. In addition, cyto c and AIF were released from mitochondria into the cytosol, which finally activated caspase-dependent and caspase-independent apoptosis processes in MC3T3-E1 cells. Our findings suggested that zinc deficiency is capable of inducing apoptosis through a mitochondria-mediated pathway in osteoblastic cells.

Abstract
The aging process is frequently characterized by an involuntary loss of muscle (sarcopenia) and bone (osteoporosis) mass. Both chronic diseases are associated with decreased metabolic rate, increased risk of falls/fracture, and, as a result, increased morbidity and loss of independence in the elderly. The quality and quantity of protein intake affects bone and muscle mass in several ways and there is evidence that increased essential amino acid or protein availability can enhance muscle protein synthesis and anabolism, as well as improve bone homeostasis in older subjects. A thorough evaluation of renal function is important, since renal function decreases with age. Finally, protein and calcium intake should be considered in the prevention or treatment of the chronic diseases osteoporosis and sarcopenia.

Abstract
Caloric restriction (CR), reduced protein, methionine, or tryptophan diets; and reduced insulin and/or IGFI intracellular signaling can extend mean and/or maximum lifespan and delay deleterious age-related physiological changes in animals. Mice and flies can shift readily between the control and CR physiological states, even at older ages. Many health benefits are induced by even brief periods of CR in flies, rodents, monkeys, and humans. In humans and nonhuman primates, CR produces most of the physiologic, hematologic, hormonal, and biochemical changes it produces in other animals. In primates, CR provides protection from type 2 diabetes, cardiovascular and cerebral vascular diseases, immunological decline, malignancy, hepatotoxicity, liver fibrosis and failure, sarcopenia, inflammation, and DNA damage. It also enhances muscle mitochondrial biogenesis, affords neuroprotection; and extends mean and maximum lifespan. CR rapidly induces antineoplastic effects in mice. Most claims of lifespan extension in rodents by drugs or nutrients are confounded by CR effects. Transcription factors and co-activators involved in the regulation of mitochondrial biogenesis and energy metabolism, including SirT1, PGC-1alpha, AMPK and TOR may be involved in the lifespan effects of CR. Paradoxically, low body weight in middle aged and elderly humans is associated with increased mortality. Thus, enhancement of human longevity may require pharmaceutical interventions.

Abstract
OBJECTIVES The Women's Health Initiative (WHI) randomized trial of calcium/vitamin D supplementation found reduced bone loss with active treatment compared to placebo. Now we examine whether the treatment affected self-reported physical functioning and objective measures of physical functioning. DESIGN A randomized, double-blind, placebo-controlled trial of 1,000 mg calcium carbonate plus 400 IU vitamin D(3) per day or matching placebo pills. SUBJECTS/SETTING The study included 33,067 women (50 to 79 years old) at 40 US study centers. MAIN OUTCOME MEASURES Physical functioning was assessed by questionnaire at enrollment in WHI, 1 year prior to calcium/vitamin D trial randomization and at study close-out (average follow-up 7.1 years). Objective physical performance and self-reported exercise measures were collected at WHI baseline (1 year prior to calcium/vitamin D enrollment) and 2 years and 4 years after calcium/vitamin D trial enrollment in a subsample (n=3,137). STATISTICAL ANALYSES PERFORMED Calcium/vitamin D effects were tested in unadjusted and interaction linear models for each of the physical function measures. Covariates were baseline total calcium intake, fracture risk score, treatment arm in the hormone therapy and dietary modification trials (ie, active drug or placebo, low-fat diet intervention or usual diet, respectively) and age. RESULTS Neither intention to treat nor high adherence analyses produced substantial effects of calcium/vitamin D compared to placebo on physical functioning or performance. The interaction analyses also did not result in differences because of calcium/vitamin D. CONCLUSIONS As the first long-term randomized trial to examine the effectiveness of calcium and vitamin D in protecting against decline of physical functioning in older women, the results did not support benefit.

Abstract
Low serum 25 hydroxyvitamin D3 (vitamin D3) is known to perturb cellular function in many tissues, including the endocrine pancreas, which are involved in obesity and type II diabetes mellitus (TIIDM). Vitamin D3 insufficiency has been linked to obesity, whether obesity is assessed by body mass index (BMI) or waist circumference (waist). Central obesity, using waist as the surrogate, is associated with the metabolic syndrome (MetSyn), insulin resistance, TIIDM and atherosclerotic cardiovascular disease (CVD). We tested how vitamin D3 was related to measures of fat mass, MetSyn markers, haemoglobin A1c (HbA1c) and MetSyn in a cross-sectional sample of 250 overweight and obese adults of different ethnicities. There were modest inverse associations of vitamin D3 with body weight (weight) (r = -0.21, p = 0.0009), BMI (r = -0.18, p = 0.005), waist (r = -0.14, p = 0.03), [but not body fat % (r = -0.08, p = 0.24)], and HbA1c (r = -0.16, p = 0.01). Multivariable regression carried out separately for BMI and waist showed a decrease of 0.74 nmol/L (p = 0.002) in vitamin D3 per 1 kg/m2 increase in BMI and a decrease of 0.29 nmol/L (p = 0.01) per 1 cm increase in waist, with each explaining approximately 3% of the variation in vitamin D3 over and above gender, age, ethnicity and season. The similar relationships of BMI and waist with vitamin D3 may have been due to associations between BMI and waist, or coincidental, where different mechanisms relating hypovitaminosis D3 to obesity occur concurrently. Previously reviewed mechanisms include that 1) low vitamin D3, may impair insulin action, glucose metabolism and various other metabolic processes in adipose and lean tissue 2) fat soluble-vitamin D3 is sequestered in the large adipose compartment, and low in serum, 3) obese people may be sensitive about their body shape, minimising their skin exposure to view and sunlight (not tested). We showed evidence for the first theory but no evidence to support the second. In the current study, serum vitamin D3 was inversely related to weight, BMI and markers of TIIDM (large waist, raised HbA1c) but not to adipose mass nor to MetSyn per se.
