    The study has been designed to investigate the effect of benfotiamine and fenofibrate in diabetes-induced experimental vascular endothelial dysfunction (VED) and nephropathy. The single administration of streptozotocin (STZ) (50 mg/kg, i.p.) produced diabetes, which was noted to develop VED and nephropathy in 8 weeks. The diabetes produced VED by attenuating acetylcholine-induced endothelium dependent relaxation, impairing the integrity of vascular endothelium, decreasing serum nitrite/nitrate concentration and increasing serum TBARS and aortic superoxide anion generation. Further, diabetes altered the lipid profile by increasing the serum cholesterol, triglycerides and decreasing the high density lipoprotein. The nephropathy was noted to be developed in the diabetic rat that was assessed in terms of increase in serum creatinine, blood urea, proteinuria, and glomerular damage. The benfotiamine (70 mg/kg, p.o.) and fenofibrate (32 mg/kg, p.o.) or lisinopril (1 mg/kg, p.o., a standard agent) treatments were started in diabetic rats after 1 week of STZ administration and continued for 7 weeks. The treatment with benfotiamine and fenofibrate either alone or in combination attenuated diabetes-induced VED and nephropathy. In addition, the combination of benfotiamine and fenofibrate was noted to be more effective in attenuating the diabetes-induced VED and nephropathy when compared to treatment with either drug alone or lisinopril. Treatment with fenofibrate normalizes the altered lipid profile in diabetic rats, whereas benfotiamine treatment has no effect on lipid alteration in diabetic rats. It may be concluded that diabetes-induced oxidative stress, lipids alteration, and consequent development of VED may be responsible for the induction of nephropathy in diabetic rats. Concurrent administration of benfotiamine and fenofibrate may provide synergistic benefits in preventing the development of diabetes-induced nephropathy by reducing the oxidative stress and lipid

    Chronic microglial activation and resulting sustained neuroinflammatory reaction are generally associated with neurodegeneration. Activated microglia acquires proinflammatory cellular profile that generates oxidative burst. Their persistent activation exacerbates inflammation, which damages healthy neurons via cytotoxic mediators, such as superoxide radical anion and nitric oxide. In our recent study, we have shown that benfotiamine (S-benzoylthiamine O-monophosphate) possesses anti-inflammatory effects. Here, the effects of benfotiamine on the pro-oxidative component of activity of LPS-stimulated BV-2 cells were investigated. The activation of microglia was accompanied by upregulation of intracellular antioxidative defense, which was further promoted in the presence of benfotiamine. Namely, activated microglia exposed to non-cytotoxic doses of benfotiamine showed increased levels and activities of hydrogen peroxide- and superoxide-removing enzymes—catalase and glutathione system, and superoxide dismutase. In addition, benfotiamine showed the capacity to directly scavenge superoxide radical anion. As a consequence, benfotiamine suppressed the activation of microglia and provoked a decrease in NO and ·O−2 production and lipid peroxidation. In conclusion, benfotiamine might silence pro-oxidative activity of microglia to alleviate/prevent oxidative damage of neighboring CNS cells. PMID:26388737

    We hypothesize that diabetes-induced impaired collateral formation after a hindlimb ligation in rats is in part caused by intracellular glycation and that overexpression of glyoxalase-I (GLO-I), i.e. the major detoxifying enzyme for advanced-glycation-endproduct (AGE) precursors, can prevent this. Wild-type and GLO-I transgenic rats with or without diabetes (induced by 55 mg/kg streptozotocin) were subjected to ligation of the right femoral artery. Laser Doppler perfusion imaging showed a significantly decreased blood perfusion recovery after 6 days in the diabetic animals compared with control animals, without any effect of Glo1 overexpression. In vivo time-of-flight magnetic resonance angiography at 7-Tesla showed a significant decrease in the number and volume of collaterals in the wild-type diabetic animals compared with the control animals. Glo1 overexpression partially prevented this decrease in the diabetic animals. Diabetes-induced impairment of arteriogenic adaptation can be partially rescued by overexpressing of GLO-I, indicating a role of AGEs in diabetes-induced impaired collateral formation. PMID:27296676

    Full Text Available Background. Smoking induces endothelial dysfunction (ED mainly by exacerbating oxidative stress (OS and inflammation. Benfotiamine, a thiamine prodrug with high bioavailability, prevents nicotine-induced vascular dysfunction in rats. It remained unknown whether this effect also occurs in humans. Methods. Therefore, 20 healthy volunteers (mean age: 38 years were investigated twice, 7–10 days apart in a randomized, cross-over, and investigator-blinded design. Vascular function was assessed by flow-mediated vasodilatation (FMD of the brachial artery and by measurements of the soluble vascular cell adhesion molecule (sVCAM-1. Investigations were performed after an overnight fast as well as 20 minutes after one cigarette smoking. On another day, the same procedure was applied following a 3-day oral therapy with benfotiamine (1050 mg/day. Ten patients were randomized to start with smoking alone, and ten started with benfotiamine. Results. Results are expressed as (mean ± SEM. Smoking acutely induced a decrease in FMD by 50% (∗∗P<0.001 versus baseline an effect significantly reduced by benfotiamine treatment to 25%∗§ (∗P<0.05 versus baseline, §P<0.05 versus smoking alone. Smoking-induced elevation in sVCAM-1 was also prevented by benfotiamine. The endothelium-independent vasodilatation remained unaltered between days. Conclusion. In healthy volunteers, smoking blunts vascular function mirrored by a decrease in FMD and an increase in sVCAM-1. Short-term treatment with benfotiamine significantly reduces these effects, showing protective vascular properties.

    Full Text Available Diabetic conditions are associated with modified brain function, namely with cognitive deficits, through largely undetermined processes. More than understanding the underlying mechanism, it is important to devise novel strategies to alleviate diabetes-induced cognitive deficits. Caffeine (a mixed antagonist of adenosine A(1 and A(2A receptors emerges as a promising candidate since caffeine consumption reduces the risk of diabetes and effectively prevents memory deficits caused by different noxious stimuli. Thus, we took advantage of a novel animal model of type 2 diabetes to investigate the behavioural, neurochemical and morphological modifications present in the hippocampus and tested if caffeine consumption might prevent these changes. We used a model closely mimicking the human type 2 diabetes condition, NONcNZO10/LtJ mice, which become diabetic at 7-11 months when kept under an 11% fat diet. Caffeine (1 g/l was applied in the drinking water from 7 months onwards. Diabetic mice displayed a decreased spontaneous alternation in the Y-maze accompanied by a decreased density of nerve terminal markers (synaptophysin, SNAP25, mainly glutamatergic (vesicular glutamate transporters, and increased astrogliosis (GFAP immunoreactivity compared to their wild type littermates kept under the same diet. Furthermore, diabetic mice displayed up-regulated A(2A receptors and down-regulated A(1 receptors in the hippocampus. Caffeine consumption restored memory performance and abrogated the diabetes-induced loss of nerve terminals and astrogliosis. These results provide the first evidence that type 2 diabetic mice display a loss of nerve terminal markers and astrogliosis, which is associated with memory impairment; furthermore, caffeine consumption prevents synaptic dysfunction and astrogliosis as well as memory impairment in type 2 diabetes.

    The present study has been designed to investigate the effect of benfotiamine, a thiamine derivative, in sodium arsenite-induced vascular endothelial dysfunction (VED) in rats. Sodium arsenite (1.5 mg(-1) kg(-1) day(-1) i.p., 2 weeks) was administered in rats to produce VED. The development of VED was assessed by employing isolated aortic ring preparation and estimating the serum and aortic concentrations of nitrite/nitrate. Further, the integrity of vascular endothelium in thoracic aorta was assessed by scanning electron microscopy. Moreover, the oxidative stress was assessed by estimating serum thiobarbituric acid reactive substances (TBARS) and aortic superoxide anion generation. The administration of sodium arsenite markedly produced VED by attenuating acetylcholine-induced endothelium-dependent relaxation, decreasing serum and aortic concentrations of nitrite/nitrate, and impairing the integrity of vascular endothelium. Further, sodium arsenite produced oxidative stress by increasing serum TBARS and aortic superoxide generation. The treatment with benfotiamine (25, 50, and 100 mg(-1) kg(-1) day(-1) p.o.) or atorvastatin (30 mg(-1) kg(-1) day(-1) p.o., a standard agent) prevented sodium arsenite-induced VED and oxidative stress. However, the beneficial effects of benfotiamine in preventing the sodium arsenite-induced VED were attenuated by co-administration with N-omega-nitro-L: -arginine methyl ester (L: -NAME) (25 mg(-1) kg(-1) day(-1), i.p.), an inhibitor of NOS. Thus, it may be concluded that benfotiamine reduces oxidative stress and activates endothelial nitric oxide synthase to enhance the generation and bioavailability of NO and subsequently improves the integrity of vascular endothelium to prevent sodium arsenite-induced experimental VED.

    Normalization of hyperglycemia, hyperlipidemia and oxidative stress is an important objective in preventing diabetes-induced cardiac dysfunction. The present study investigated the effects of the fruit juice obtained from Emblica officinalis on myocardial dysfunction in diabetic rats. Diabetes was induced by streptozotocin (STZ), and the rats were treated with E officinalis fruit juice for eight weeks. Injection of STZ produced loss of body weight, polydypsia, polyphagia, hyperglycemia, hypoinsulinemia and dyslipidemia. It also produced hypertension, bradycardia, hypertrophy and myocardial functional alterations associated with an increase in serum lactate dehydrogenase and creatinine kinase-MB levels. Treatment with the fruit juice not only prevented STZ-induced loss of body weight, increases in water and food intake, increases in serum glucose levels and disturbed lipid profile, but also an increase in serum lactate dehydrogenase and creatinine kinase-MB levels, and increased myocardial hypertrophy and cardiomyopathy. There was an increase in the area under the curve (AUC) for glucose, and a decrease in AUCinsulin was observed in diabetic rats; treatment decreased AUCglucose but not AUCinsulin or hyperinsulinemia. There was a decrease in antioxidant enzyme levels (in superoxide dismutase, reduced glutathione and catalase) in diabetic hearts, which could be improved by treatment with fruit juice. The present data suggest that fruit juice may be beneficial for the treatment of myocardial damage associated with type 1 diabetes mellitus. The activity of E officinalis fruit juice can be attributed to the concentration of polyphenol present. PMID:22065939

    Microglial cells are resident immune cells of the central nervous system (CNS), recognized as key elements in the regulation of neural homeostasis and the response to injury and repair. As excessive activation of microglia may lead to neurodegeneration, therapeutic strategies targeting its inhibition were shown to improve treatment of most neurodegenerative diseases. Benfotiamine is a synthetic vitamin B1 (thiamine) derivate exerting potentially anti-inflammatory effects. Despite the encouraging results regarding benfotiamine potential to alleviate diabetic microangiopathy, neuropathy and other oxidative stress-induced pathological conditions, its activities and cellular mechanisms during microglial activation have yet to be elucidated. In the present study, the anti-inflammatory effects of benfotiamine were investigated in lipopolysaccharide (LPS)-stimulated murine BV-2 microglia. We determined that benfotiamine remodels activated microglia to acquire the shape that is characteristic of non-stimulated BV-2 cells. In addition, benfotiamine significantly decreased production of pro-inflammatory mediators such as inducible form of nitric oxide synthase (iNOS) and NO; cyclooxygenase-2 (COX-2), heat-shock protein 70 (Hsp70), tumor necrosis factor alpha α (TNF-α), interleukin-6 (IL-6), whereas it increased anti-inflammatory interleukin-10 (IL-10) production in LPS stimulated BV-2 microglia. Moreover, benfotiamine suppressed the phosphorylation of extracellular signal-regulated kinases 1/2 (ERK1/2), c-Jun N-terminal kinases (JNK) and protein kinase B Akt/PKB. Treatment with specific inhibitors revealed that benfotiamine-mediated suppression of NO production was via JNK1/2 and Akt pathway, while the cytokine suppression includes ERK1/2, JNK1/2 and Akt pathways. Finally, the potentially protective effect is mediated by the suppression of translocation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) in the nucleus. Therefore, benfotiamine may

    The study has been designed to investigate the effect of benfotiamine, a thiamine derivative, in nicotine and uric acid-induced vascular endothelial dysfunction (VED) in rats. Nicotine (2 mg kg(-1)day(-1), i.p., 4 weeks) and uric acid (150 mg kg(-1)day(-1), i.p., 3 weeks) were administered to produce VED in rats. The development of VED was assessed by employing isolated aortic ring preparation and estimating serum and aortic concentration of nitrite/nitrate. Further, the integrity of vascular endothelium was assessed using the scanning electron microscopy (SEM) of thoracic aorta. Moreover, the oxidative stress was assessed by estimating serum thiobarbituric acid reactive substances (TBARS) and aortic superoxide anion generation. The administration of nicotine and uric acid produced VED by impairing the integrity of vascular endothelium and subsequently decreasing serum and aortic concentration of nitrite/nitrate and attenuating acetylcholine-induced endothelium dependent relaxation. Further, nicotine and uric acid produced oxidative stress, which was assessed in terms of increase in serum TBARS and aortic superoxide generation. However, treatment with benfotiamine (70 mg kg(-1)day(-1), p.o.) or atorvastatin (30 mg kg(-1)day(-1) p.o., a standard agent) markedly prevented nicotine and uric acid-induced VED and oxidative stress by improving the integrity of vascular endothelium, increasing the concentration of serum and aortic nitrite/nitrate, enhancing the acetylcholine-induced endothelium dependent relaxation and decreasing serum TBARS and aortic superoxide anion generation. Thus, it may be concluded that benfotiamine reduces the oxidative stress and consequently improves the integrity of vascular endothelium and enhances the generation of nitric oxide to prevent nicotine and uric acid-induced experimental VED.

    Catalase is an antioxidant enzyme that specifically catabolizes hydrogen peroxide (H2O2). Overexpression of catalase via a heart-specific promoter (CAT-TG) was reported to reduce diabetes-induced accumulation of reactive oxygen species (ROS) and further prevent diabetes-induced pathological abnormalities, including cardiac structural derangement and left ventricular abnormity in mice. However, the mechanism by which catalase overexpression protects heart function remains unclear. This study found that activation of a ROS-dependent NF-κB signaling pathway was downregulated in hearts of diabetic mice overexpressing catalase. In addition, catalase overexpression inhibited the significant increase in nitration levels of key enzymes involved in energy metabolism, including α-oxoglutarate dehydrogenase E1 component (α-KGD) and ATP synthase α and β subunits (ATP-α and ATP-β). To assess the effects of the NF-κB pathway activation on heart function, Bay11-7082, an inhibitor of the NF-κB signaling pathway, was injected into diabetic mice, protecting mice against the development of cardiac damage and increased nitrative modifications of key enzymes involved in energy metabolism. In conclusion, these findings demonstrated that catalase protects mouse hearts against diabetic cardiomyopathy, partially by suppressing NF-κB-dependent inflammatory responses and associated protein nitration.

    Background Lipid-soluble thiamine precursors have a much higher bioavailability than genuine thiamine and therefore are more suitable for therapeutic purposes. Benfotiamine (S-benzoylthiamine O-monophosphate), an amphiphilic S-acyl thiamine derivative, prevents the progression of diabetic complications, probably by increasing tissue levels of thiamine diphosphate and so enhancing transketolase activity. As the brain is particularly sensitive to thiamine deficiency, we wanted to test whether i...

    Full Text Available Background:In peritoneal dialysis (PD residual renal function (RRF fundamentally contributes to improved quality of life and patient survival. High glucose and advanced glycation end-products (AGE contribute locally to peritoneal and systemically to renal damage. Integrity of podocyte structure and function is of special importance to preserve RRF. Benfotiamine could counteract the glucose and AGE mediated toxicity by blocking hyperglycemia associated podocyte damage via the pentose phosphate pathway.Methods: A human differentiated podocyte cell line was incubated with control solution (Control, 2.5% glucose solution (Glucose and 2.5% PD fluid (PDF for 48 h either ± 50 μM benfotiamine.Podocyte damage and potential benefit of benfotiamine were analyzed using immunofluorescence, western blot analysis, and a functional migration assay. For quantitation, a semiquantitative score was used. Results:When incubating podocytes with benfotiamine, Glucose and PDF mediated damage was reduced resulting in lower expression of AGE and intact podocin and ZO-1 localization. The reorganization of the actin cytoskeleton was restored in the presence of benfotiamine as functional podocyte motility reached Control level. Decreased level of inflammation could be shown as well as reduced podocyte apoptosis.Conclusions:These data suggest that benfotiamine protects podocytes from Glucose and PDF mediated dysfunction and damage, in particular with regard to cytoskeletal reorganization, motility, inflammation and podocyte survival.

    Apatinib, a novel and selective inhibitor of vascular endothelial growth factor (VEGF) receptor 2, has been demonstrated recently to exhibit anticancer efficacy by inhibiting the VEGF signaling pathway. Given the importance of VEGF in retinal vascular leakage, the present study was designed to investigate whether apatinib-loaded polymeric nanoparticles inhibit VEGF-mediated retinal vascular hyperpermeability and block diabetes-induced retinal vascular leakage. For the delivery of water-insoluble apatinib, the drug was encapsulated in nanoparticles composed of human serum albumin (HSA)-conjugated polyethylene glycol (PEG). In vitro paracellular permeability and transendothelial electric resistance assays showed that apatinib-loaded HSA-PEG (Apa-HSA-PEG) nanoparticles significantly inhibited VEGF-induced endothelial hyperpermeability in human retinal microvascular endothelial cells. In addition, they substantially reduced the VEGF-induced junctional loss and internalization of vascular endothelial-cadherin, a major component of endothelial junction complexes. In vivo intravitreal injection of Apa-HSA-PEG nanoparticles in mice blocked VEGF-induced retinal vascular leakage. These in vitro and in vivo data indicated that Apa-HSA-PEG nanoparticles efficiently blocked VEGF-induced breakdown of the blood–retinal barrier. In vivo experiments with streptozotocin-induced diabetic mice showed that an intravitreal injection of Apa-HSA-PEG nanoparticles substantially inhibited diabetes-induced retinal vascular leakage. These results demonstrated, for the first time, that apatinib-loaded nanoparticles may be a promising therapeutic agent for the prevention and treatment of diabetes-induced retinal vascular disorders.

    Full Text Available Vascular complications are the leading cause of morbidity and mortality in patients with diabetes. Quercetin is an important flavonoid with antioxidant and anti-inflammatory activity. Here, the effect of quercetin on diabetes-induced exaggerated vasoconstriction in insulin deficient and insulin resistant rat models was investigated. Insulin deficiency was induced by streptozotocin while, insulin resistance by fructose. Rats were left 8 weeks or 12 weeks after STZ or fructose administration respectively. Quercetin was daily administered in the last 6 weeks. Then, tail blood pressure (BP was recorded in conscious animals; concentration-response curves for phenylephrine (PE and KCl were studied in thoracic aorta rings. Non-fasting blood glucose level, serum insulin level, insulin resistance index, serum tumour necrosis factor-α (TNF-α and serum C-reactive protein (CRP were determined. Nuclear transcription factor-κB (NF-κB was assessed by immunofluorescence technique. Histopathological examination was also performed. The results showed that quercetin protected against diabetes-induced exaggerated vasoconstriction and reduced the elevated blood pressure. In addition, quercetin inhibited diabetes associated adventitial leukocyte infiltration, endothelial pyknosis and increased collagen deposition. These effects were accompanied with reduction in serum level of both TNF-α and CRP and inhibition of aortic NF-κB by quercetin in both models of diabetes. On the other hand, quercetin did not affect glucose level in any of the used diabetic models. This suggests that the protective effect of quercetin is mediated by its anti-inflammatory effect rather than its metabolic effects. In summary, quercetin is potential candidate to prevent diabetic vascular complications in both insulin deficiency and resistance via its inhibitory effect on inflammatory pathways especially NF-κB signaling.

    A novel method was developed for spectral resolution and further determination of five-component mixture including Vitamin B complex (B1, B6, B12 and Benfotiamine) along with the commonly co-formulated Diclofenac. The method is simple, sensitive, precise and could efficiently determine the five components by a complementary application of two different techniques. The first is univariate second derivative method that was successfully applied for determination of Vitamin B12. The second is Multivariate Curve Resolution using the Alternating Least Squares method (MCR-ALS) by which an efficient resolution and quantitation of the quaternary spectrally overlapped Vitamin B1, Vitamin B6, Benfotiamine and Diclofenac sodium were achieved. The effect of different constraints was studied and the correlation between the true spectra and the estimated spectral profiles were found to be 0.9998, 0.9983, 0.9993 and 0.9933 for B1, B6, Benfotiamine and Diclofenac, respectively. All components were successfully determined in tablets and capsules and the results were compared to HPLC methods and they were found to be statistically non-significant.

Objective: This study was undertaken to examine the effects of gallic acid in myocardial dysfunctions associated with type-1 diabetes. Materials and Methods: Diabetes was induced by single intravenous injection of streptozotocin (STZ, 50 mg/kg i.v.. Gallic acid was administered daily at three different doses (100, 50, and 25 mg/kg p.o. for 8 weeks at the end of which blood samples were collected and analyzed for various biochemical parameters. Results: Injection of STZ produced significant loss of body weight (BW, polyphagia, polydypsia, hyperglycemia, hypoinsulinemia, hyperlipidemia, hypertension, bradycardia, and myocardial functional alterations. Treatment with gallic acid significantly lowered fasting glucose, the AUC glucose level in a dose-dependent manner; however, the insulin level was not increased significantly at same the dose and prevented loss of BW, polyphagia, and polydypsia in diabetic rats. It also prevented STZ-induced hyperlipidemia, hypertension, bradycardia, structural alterations in cardiac tissue such as increase in force of contraction, left ventricular weight to body weight ratio, collagen content, protein content, serum lactate dehydrogenase, and creatinine kinase levels in a dose-dependent manner. Further, treatment also produced reduction in lipid peroxidation and increase in antioxidant parameters in heart of diabetic rats. Conclusion: The results of this study suggest that gallic acid to be beneficial for the treatment of myocardial damage associated with type-1 diabetes.

Direct and indirect effects of PBM on the retina also were studied.Diabetes was induced in C57Bl/6J mice using streptozotocin. Some diabetics were exposed to PBM therapy (4 min/day; 670 nm daily. In one study, mice were diabetic for 4 weeks before initiation of PBM for an additional 10 weeks. Retinal oxidative stress, inflammation, and retinal function were measured. In some mice, heads were covered with a lead shield during PBM to prevent direct illumination of the eye, or animals were treated with an inhibitor of heme oxygenase-1. In a second study, PBM was initiated immediately after onset of diabetes, and administered daily for 2 months. These mice were examined using manganese-enhanced MRI to assess effects of PBM on transretinal calcium channel function in vivo.PBM intervention improved diabetes-induced changes in superoxide generation, leukostasis, expression of ICAM-1, and visual performance. PBM acted in part remotely from the retina because the beneficial effects were achieved even with the head shielded from the light therapy, and because leukocyte-mediated cytotoxicity of retinal endothelial cells was less in diabetics treated with PBM. SnPP+PBM significantly reduced iNOS expression compared to PBM alone, but significantly exacerbated leukostasis. In study 2, PBM largely mitigated diabetes-induced retinal calcium channel dysfunction in all retinal layers.PBM induces retinal protection against abnormalities induced by diabetes in pigmented animals, and even as an intervention. Beneficial effects on the retina likely are mediated by both direct and indirect mechanisms. PBM is a novel non-pharmacologic treatment strategy to inhibit early changes of diabetic

Groups 3–6 were treated by 100, 200, and 400 mg/kg of the extract or metformin, respectively, for 6 weeks (orally. Results. In passive avoidance test, the latency to enter the dark compartment in Diabetic group was lower than that of Control group (P<0.01. In Dia-Ext 100, Dia-Ext 200, and Dia-Ext 400 and Metformin groups, the latencies were higher than those of Diabetic group (P<0.01. Lipid peroxides levels (reported as malondialdehyde, MDA, concentration in the brain of Diabetic group were higher than Control (P<0.001. Treatment by all doses of the extract and metformin decreased the MDA concentration (P<0.01. Conclusions. The results of present study showed that metformin and the hydroalcoholic extract of Teucrium polium prevent diabetes-induced memory deficits in rats. Protection against brain tissues oxidative damage might have a role in the beneficial effects of the extract and metformin.

    Glucagon-like peptide-1 (GLP-1), as a member of the incretin family, has a role in glucose homeostasis, its receptors distributed throughout the body, including the heart. The aim was to investigate cardiac lesions following diabetes induction, and the potential effect of GLP-1 on this type of lesions and the molecular mechanism driving this activity. Adult male rats were classified into: normal, diabetic, 4-week high-dose exenatide-treated diabetic rats, 4-week low-dose exenatide-treated diabetic rats, and 1-week exenatide-treated diabetic rats. The following parameters were measured: in blood: glucose, insulin, lactate dehydrogenase (LDH), total creatine kinase (CK), creatine kinase MB isoenzyme (CK-MB), and CK-MB relative index; in cardiac tissue: lipid peroxide (LPO) and some antioxidant enzymes. The untreated diabetic group displayed significant increases in blood level of glucose, LDH, and CK-MB, and cardiac tissue LPO, and a significant decrease in cardiac tissue antioxidant enzymes. GLP-1 supplementation in diabetic rats definitely decreased the hyperglycemia and abolished the detrimental effects of diabetes on the cardiac tissue. The effect of GLP-1 on blood glucose and on the heart also appeared after a short supplementation period (1 week). It can be concluded that GLP-1 has beneficial effects on diabetes-induced oxidative cardiac tissue damage, most probably via its antioxidant effect directly acting on cardiac tissue and independent of its hypoglycemic effect.

    We hypothesized that the retina of diabetic animals would be unusually acidic due to increased glycolytic metabolism. Acidosis in tumors and isolated retina has been shown to lead to increased VEGF. To test the hypothesis we have measured the transretinal distribution of extracellular H(+) concentration (H(+)-profiles) in retinae of control and diabetic dark-adapted intact Long-Evans rats with ion-selective electrodes. Diabetes was induced by intraperitoneal injection of streptozotocin. Intact rat retinae are normally more acidic than blood with a peak of [H(+)]o in the outer nuclear layer (ONL) that averages 30 nM higher than H(+) in the choroid. Profiles in diabetic animals were similar in shape, but diabetic retinae began to be considerably more acidic after 5 weeks of diabetes. In retinae of 1-3 month diabetics the difference between the ONL and choroid was almost twice as great as in controls. At later times, up to 6 months, some diabetics still demonstrated abnormally high levels of [H(+)]o, but others were even less acidic than controls, so that the average level of acidosis was not different. Greater variability in H(+)-profiles (both between animals and between profiles recorded in one animal) distinguished the diabetic retinae from controls. Within animals, this variability was not random, but exhibited regions of higher and lower H(+). We conclude that retinal acidosis begins to develop at an early stage of diabetes (1-3 months) in rats. However, it does not progress, and the acidity of diabetic rat retina was diminished at later stages (3-6 months). Also the diabetes-induced acidosis has a strongly expressed local character. As result, the diabetic retinas show much wider variability in [H(+)] distribution than controls. pH influences metabolic and neural processes, and these results suggest that local acidosis could play a role in the pathogenesis of diabetic retinopathy.

    Full Text Available Abstract Background Hyperglycemia-induced changes in vascular wall structure contribute to the pathogenesis of diabetic microvascular and macrovascular complications. Matrix metalloproteinases (MMP, a family of proteolytic enzymes that degrade extracellular matrix (ECM proteins, are essential for vascular remodeling. We have shown that endothelin-1 (ET-1 mediates increased MMP activity and associated vascular remodeling in Type 2 diabetes. However, the effect of Type 2 diabetes and/or ET-1 on the regulation of ECM and MMP gene expression in different vascular beds remains unknown. Methods Aorta and mesenteric artery samples were isolated from control, Type 2 diabetic Goto-Kakizaki (GK rats and GK rats treated with ETA antagonist ABT-627. Gene expression profile of MMP-2, MMP-9, MT1-MMP, fibronectin, procollagen type 1, c-fos and c-jun, were determined by quantitative real-time (qRT PCR. In addition, aortic gene expression profile was evaluated by an ECM & Adhesion Molecules pathway specific microarray approach. Results Analysis of the qRT-PCR data demonstrated a significant increase in mRNA levels of MMPs and ECM proteins as compared to control animals after 6 weeks of mild diabetes. Futhermore, these changes were comparable in aorta and mesentery samples. In contrast, treatment with ETA antagonist prevented diabetes-induced changes in expression of MMPs and procollagen type 1 in mesenteric arteries but not in aorta. Microaarray analysis provided evidence that 27 extracellular matrix genes were differentially regulated in diabetes. Further qRT-PCR with selected 7 genes confirmed the microarray data. Conclusion These results suggest that the expression of both matrix scaffold protein and matrix degrading MMP genes are altered in macro and microvascular beds in Type 2 diabetes. ETA antagonism restores the changes in gene expression in the mesenteric bed but not in aorta suggesting that ET-1 differentially regulates microvascular gene expression in

    Full Text Available OBJECTIVE: Diabetic retinopathy, a major cause of blindness, is characterized by increased expression of vascular endothelial growth factor (VEGF, leukocyte attachment to the vessel walls and increased vascular permeability. Previous work has shown that reactive oxygen species (ROS produced by the superoxide generating enzyme NOX2/NADPH oxidase play a crucial role in the vascular pathology. The aim of this work was to identify the cellular sources of the damaging NOX2 activity by studies using bone marrow chimera mice. METHODS: Bone marrow cells were collected from the femurs and tibias of wild type and NOX2 deficient (NOX2(-/- donor mice and injected intravenously into lethally irradiated NOX2(-/- and wild type recipients. Following recovery from radiation, mice were rendered diabetic by streptozotocin injections. The following groups of bone marrow chimeras were studied: non-diabetic WT → WT, diabetic WT → WT, diabetic WT → NOX2(-/-, diabetic NOX2(-/- → WT. After 4 weeks of diabetes, early signs of retinopathy were examined by measuring ROS, expression of VEGF and ICAM-1, leukocyte attachment to the vessel wall and vascular permeability. RESULTS: The retinas of the diabetic WT → WT chimeras showed significant increases in ROS as compared with the non-diabetic chimeras. These diabetes-induced alterations were correlated with increases in expression of VEGF and ICAM-1, leukocyte adhesion and vascular permeability. Each of these diabetes-induced alterations were significantly attenuated in the diabetic WT → NOX2(-/- and NOX2(-/- → WT chimera groups (p<0.05. CONCLUSION: NOX2-generated ROS produced by both bone marrow-derived cells and resident retinal cells contribute importantly to retinal vascular injury in the diabetic retina. Targeting NOX2 in bone marrow and/or retinal cells may represent a novel therapeutic strategy for the treatment/prevention of vascular injury in the diabetic retina.

    Full Text Available We aim to investigate the effects of curcumin on preventing diabetes-induced vascular inflammation in association with its actions on Txnip, ICAM-1, and NOX2 enzyme expressions. Male Wistar rats were divided into four groups: control (CON, diabetic (DM; streptozotocin (STZ, i.v. 55 mg/kg BW, control-treated with curcumin (CONCUR; 300 mg/kg BW, and diabetes treated with curcumin (DMCUR; 300 mg/kg BW. 12th week after STZ injection, iris blood perfusion, leukocyte adhesion, Txnip, p47phox, and malondialdehyde (MDA levels were determined by using laser Doppler, intravital fluorescent confocal microscopy, Western Blot analysis, and TBAR assay, respectively. The iris blood perfusion of DM and DMCUR was decreased significantly compared to CON and CONCUR (P<0.001. Plasma glucose and HbA1c of DM and DMCUR were increased significantly compared to CON and CONCUR (P<0.001. Leukocyte adhesion, ICAM-1, p47phox expression, and MDA levels in DM were increased significantly compared to CON, CONCUR, and DMCUR (P<0.05. Txnip expression in DM and DMCUR was significantly higher than CON and CONCUR (P<0.05. From Pearson’s analysis, the correlation between the plasma MDA level and the endothelial functions was significant. It suggested that curcumin could ameliorate diabetic vascular inflammation by decreasing ROS overproduction, reducing leukocyte-endothelium interaction, and inhibiting ICAM-1 and NOX2 expression.

    This study investigated the effects of flaxseed (Linum usitatissimum L.) intake on general metabolism, pentose phosphate pathway (PPP) and glutathione-dependent enzymes in diabetic rats. Diabetes was induced by streptozotocin injection (40 mg/kg, i.p.) and the enzyme activities were determined spectrophotometrically. Diabetic and control rats were divided in two subgroups, one untreated, and one treated with flaxseed (0.714 g/kg body weight/day; orally) for 12 weeks. Flaxseed ameliorated decreased body weight (p < .05) and increased blood glucose (p < .001), triglyceride (p < .001), ALT (p < .001) and AST (p < .001) in diabetic rats. Diabetes resulted in increased glucose-6-phosphate dehydrogenase (G6PD) (p < .05) and decreased glutathione-S-transferase (GST) (p < .01), but unchanged 6-phosphogluconate dehydrogenase (6PGD) and glutathione reductase (GR) in the brain of rats. These alterations were partially improved by flaxseed in comparison to diabetic untreated group (p < .05). G6PD, 6PGD, GR were elevated (p < .001), while GST unchanged in the lung of diabetic untreated group compared to control. Flaxseed partially prevented the increase in 6PGD (p < .05) and GR (p < .01), but unaffected G6PD in the lung of diabetic rats. G6PD (p < .001), 6PGD (p < .05), GR (p < .001) were augmented, while GST showed a significant (p < .001) depletion in the pancreas of diabetic untreated rats compared to control. Diabetic alterations observed in pancreatic enzyme activities were significantly prevented by flaxseed. Furthermore, a remarkable decrease in 6PGD (p < .001) and an increase in G6PD (threefold of control) were found in the lens of diabetic untreated group that were completely prevented by flaxseed (p < .001). Flaxseed has beneficial effects against diabetes-induced glucotoxicity by modulating G6PD, 6PGD, GR and GST activities in tissues.

    Full Text Available BACKGROUND: Lipotoxicity is a key feature of the pathogenesis of diabetic kidney disease, and is attributed to excessive lipid accumulation (hyperlipidemia. Increasing evidence suggests that fibroblast growth factor (FGF21 has a crucial role in lipid metabolism under diabetic conditions. OBJECTIVE: The present study investigated whether FGF21 can prevent hyperlipidemia- or diabetes-induced renal damage, and if so, the possible mechanism. METHODS: Mice were injected with free fatty acids (FFAs, 10 mg/10 g body weight or streptozotocin (150 mg/kg to establish a lipotoxic model or type 1 diabetic model, respectively. Simultaneously the mice were treated with FGF21 (100 µg/kg for 10 or 80 days. The kidney weight-to-tibia length ratio and renal function were assessed. Systematic and renal lipid levels were detected by ELISA and Oil Red O staining. Renal apoptosis was examined by TUNEL assay. Inflammation, oxidative stress, and fibrosis were assessed by Western blot. RESULTS: Acute FFA administration and chronic diabetes were associated with lower kidney-to-tibia length ratio, higher lipid levels, severe renal apoptosis and renal dysfunction. Obvious inflammation, oxidative stress and fibrosis also observed in the kidney of both mice models. Deletion of the fgf21 gene further enhanced the above pathological changes, which were significantly prevented by administration of exogenous FGF21. CONCLUSION: These results suggest that FFA administration and diabetes induced renal damage, which was further enhanced in FGF21 knock-out mice. Administration of FGF21 significantly prevented both FFA- and diabetes-induced renal damage partially by decreasing renal lipid accumulation and suppressing inflammation, oxidative stress, and fibrosis.

Objective: The present study was designed to evaluate the protective role of petroleum ether extract of Cissus quadrangularis (PECQ on diabetes-induced delayed fetal skeletal ossification. Materials and Methods : Female Wistar rats were rendered diabetic with streptozotocin (STZ, 40 mg/kg, intraperitonial before mating. After confirmation of pregnancy, the pregnant rats were divided into three groups: normal control group, diabetic control group, and diabetic + CQ group. The diabetic + CQ group pregnant rats were treated with PECQ (500 mg/kg body weight throughout their gestation period. Immediately after delivery, pups were collected from all three groups and processed for alizarin red S-alcian blue staining in order to examine the pattern of skeletal ossification. Results : Fewer ossification centers and decreased extent of ossification of forelimb and hindlimb bones were observed in the neonatal pups of diabetic control group as compared to those in the normal control group. PECQ pretreatment significantly restored the ossification centers and improved the extent of ossification of forelimb and hindlimb bones in the neonatal pups of diabetic + CQ group as compared to those in the diabetic control group. Conclusions : The results suggested that PECQ treatment is effective against diabetes-induced delayed fetal skeletal ossification. However, further studies on the isolation and characterization of active constituents of PECQ, which can cross the placental barrier and are responsible for the bone anabolic activity are warranted.

    Abnormalities in lysosomal function have been reported in diabetes, aging, and age-related degenerative diseases. These lysosomal abnormalities are an early manifestation of neurodegenerative diseases and often precede the onset of clinical symptoms such as learning and memory deficits; however, the mechanism underlying lysosomal dysfunction is not known. In the current study, we investigated the mechanism underlying lysosomal dysfunction in the cortex and hippocampi, key structures involved in learning and memory, of a type 2 diabetes (T2D) mouse model, the leptin receptor deficient db/db mouse. We demonstrate for the first time that diabetes leads to destabilization of lysosomes as well as alterations in the protein expression, activity, and/or trafficking of two lysosomal enzymes, hexosaminidase A and cathepsin D, in the hippocampus of db/db mice. Pioglitazone, a thiazolidinedione (TZD) commonly used in the treatment of diabetes due to its ability to improve insulin sensitivity and reverse hyperglycemia, was ineffective in reversing the diabetes-induced changes on lysosomal enzymes. Our previous work revealed that pioglitazone does not reverse hypercholesterolemia; thus, we investigated whether cholesterol plays a role in diabetes-induced lysosomal changes. In vitro, cholesterol promoted the destabilization of lysosomes, suggesting that lysosomal-related changes associated with diabetes are due to elevated levels of cholesterol. Since lysosome dysfunction precedes neurodegeneration, cognitive deficits, and Alzheimer's disease neuropathology, our results may provide a potential mechanism that links diabetes with complications of the central nervous system.

    Diabetes-induced glutathione (GSH) decrease is usually ascribed to GSH oxidation. Here we investigate, in streptozotocin-treated rats, if impairment of GSH synthesis contributes to GSH decrease in diabetic liver, and if antioxidant treatments can provide protection. Diabetic rats were divided into 3 groups: untreated diabetic rats (UD); N-acetyl-cysteine (NAC)-treated diabetic rats; taurine (TAU)-treated diabetic rats; a group of non-streptozotocin-treated rats was used as control (CTR). All rats were sacrificed at 40 weeks of age. Diabetes induced hepatic glutathione decrease, but oxidized glutathione (GSSG) did not increase significantly. Accumulations of cysteine and cysteinyl-glycine in UD suggest respectively decreased glutathione synthesis and increased loss through the plasma membrane with subsequent degradation. Decreased expression of γ-glutamyl-cysteine synthetase in UD is consistent with repressed GSH synthesis. Moreover, diabetes caused increase of GSSG/GSH ratio and induction of heme oxygenase-1, both signs of oxidative stress. Supplementation with NAC or TAU resulted in amelioration of glutathione levels, probably depending on antioxidant activity, more efficient glutathione synthesis and decreased GSH loss and degradation. In conclusion, impaired synthesis and increased loss and degradation of GSH appear to contribute to a decrease in GSH levels in diabetic liver. NAC and TAU are able to partially protect from oxidative stress and GSH decrease, while enhancing GSH synthesis and restricting GSH loss.

  17. Protection by sulforaphane from type 1 diabetes-induced testicular apoptosis is associated with the up-regulation of Nrf2 expression and function

    International Nuclear Information System (INIS)

    Diabetes-induced testicular apoptosis is predominantly due to increased oxidative stress. The nuclear factor-erythroid 2-related factor 2 (Nrf2), as a master transcription factor in controlling anti-oxidative systems, is able to be induced by sulforaphane (SFN). To examine whether SFN prevents testicular apoptosis, type 1 diabetic mouse model was induced with multiple low-dose streptozotocin. Diabetic and age-matched control mice were treated with and without SFN at 0.5 mg/kg daily in five days of each week for 3 months and then kept until 6 months. Diabetes significantly increased testicular apoptosis that was associated with endoplasmic reticulum stress and mitochondrial cell death pathways, shown by the increased expression of C/EBP homologous protein (CHOP), cleaved caspase-12, Bax to Bcl2 expression ratio, and cleaved caspase-3. Diabetes also significantly increased testicular oxidative damage, inflammation and fibrosis, and decreased germ cell proliferation. All these diabetic effects were significantly prevented by SFN treatment for the first 3 months, and the protective effect could be sustained at 3 months after SFN treatment. SFN was able to up-regulate Nrf2 expression and function. The latter was reflected by the increased phosphorylation of Nrf2 at Ser40 and expression of Nrf2 downstream antioxidants at mRNA and protein levels. These results suggest that type 1 diabetes significantly induced testicular apoptosis and damage along with increasing oxidative stress and cell death and suppressing Nrf2 expression and function. SFN is able to prevent testicular oxidative damage and apoptosis in type 1 diabetes mice, which may be associated with the preservation of testicular Nrf2 expression and function under diabetic condition. - Highlights: • Sulforaphane (SFN) could attenuate diabetes-induced germ cell apoptosis. • SFN could preserve germ cell proliferation under diabetic conditions. • SFN testicular protection was sustained until 3 months after

    Background Quail eggs as a food item have recently been introduced into the diet of some Cameroonians. These eggs are being sold in local markets, but with many unfounded health claims. One claim is that quail eggs can reduce blood glucose levels in diabetics. It was therefore necessary to evaluate the effect of consuming quail eggs on blood glucose levels, lipid profiles, and oxidative stress parameters in diabetes-induced rats. Methods Twenty Wistar rats weighing, on average, 250 g were divided into four groups of five rats each. Group 1 consisted of rats with normal blood glucose, and the other three groups (2, 3, and 4) consisted of diabetes-induced rats achieved by intravenous injection of streptozotocin. During 16 days, rats in groups 1 and 2 received distilled water; and rats in groups 3 and 4 received quail and chicken eggs, respectively, with gastroesophageal probe at a dose of 1 mL/200 g body weight. Fasting blood glucose levels were determined in all the groups on the 1st, 7th, 14th, and 17th days after induction of diabetes. On the 17th day, the fasting rats were sacrificed, and blood and liver samples were collected for biochemical analyses. Results In 17 days, the consumption of quail and chicken eggs had no effect on blood glucose levels of diabetic rats. Total cholesterol levels were higher in groups 3 (75.59 mg/dL) and 4 (59.41 mg/dL) compared to group 2 (55.67 mg/dl), although these differences were not significant (all p>0.05). Triglyceride levels were significantly higher (pdiabetic rats at the tested dose had no effect on blood glucose level and oxidative stress parameters and may have a negative effect on lipid profile.

    Full Text Available Endothelial dysfunction is characterized by reduced bioavailability of NO due to its inactivation to form peroxynitrite or reduced expression of eNOS. Here, we examine the causal role of peroxynitrite in mediating diabetes-induced endothelial dysfunction. Diabetes was induced by STZ-injection, and rats received the peroxynitrite decomposition catalyst (FeTTPs, 15 mg/Kg/day for 4 weeks. Vasorelaxation to acetylcholine, oxidative-stress markers, RhoA activity, and eNOS expression were determined. Diabetic coronary arteries showed significant reduction in ACh-mediated maximal relaxation compared to controls. Diabetic vessels showed also significant increases in lipid-peroxides, nitrotyrosine, and active RhoA and 50% reduction in eNOS mRNA expression. Treatment of diabetic animals with FeTTPS blocked these effects. Studies in aortic endothelial cells show that high glucose or peroxynitrite increases the active RhoA kinase levels and decreases eNOS expression and NO levels, which were reversed with blocking peroxynitrite or Rho kinase. Together, peroxynitrite can suppress eNOS expression via activation of RhoA and hence cause vascular dysfunction.

    Full Text Available Retinal neuropathy is an early event in the development of diabetic retinopathy. One of the potential enzymes that are activated by oxidative stress in the diabetic retina is poly (ADP-ribose polymerase (PARP. We investigated the effect of the PARP inhibitor 1,5-isoquinolinediol on the expression of the neurodegeneration mediators and markers in the retinas of diabetic rats. After two weeks of streptozotocin-induced diabetes, rats were treated with 1,5-isoquinolinediol (3 mg/kg/day. After 4 weeks of diabetes, the retinas were harvested and the levels of reactive oxygen species (ROS were determined fluorometrically and the expressions of PARP, phosporylated-ERK1/2, BDNF, synaptophysin, glutamine synthetase (GS, and caspase-3 were determined by Western blot analysis. Retinal levels of ROS, PARP-1/2, phosphorylated ERK1/2, and cleaved caspase-3 were significantly increased, whereas the expressions of BDNF synaptophysin and GS were significantly decreased in the retinas of diabetic rats, compared to nondiabetic rats. Administration of 1,5-isoquinolinediol did not affect the metabolic status of the diabetic rats, but it significantly attenuated diabetes-induced upregulation of PARP, ROS, ERK1/2 phosphorylation, and cleaved caspase-3 and downregulation of BDNF, synaptophysin, and GS. These findings suggest a beneficial effect of the PARP inhibitor in increasing neurotrophic support and ameliorating early retinal neuropathy induced by diabetes.

    Objective The beneficial effects of silymarin have been extensively studied in the context of inflammation and cancer treatment, yet much less is known about its therapeutic effect on diabetes. The present study was aimed to investigate the cytoprotective activity of silymarin against diabetes-induced cardiomyocyte apoptosis. Methods Rats were randomly divided into: control group, untreated diabetes group and diabetes group treated with silymarin (120 mg/kg·d) for 10 d. Rats were sacrificed, and the cardiac muscle specimens and blood samples were collected. The immunoreactivity of caspase-3 and Bcl-2 in the cardiomyocytes was measured. Total proteins, glucose, insulin, creatinine, AST, ALT, cholesterol, and triglycerides levels were estimated. Results Unlike the treated diabetes group, cardiomyocyte apoptosis increased in the untreated rats, as evidenced by enhanced caspase-3 and declined Bcl-2 activities. The levels of glucose, creatinine, AST, ALT, cholesterol, and triglycerides declined in the treated rats. The declined levels of insulin were enhanced again after treatment of diabetic rats with silymarin, reflecting a restoration of the pancreaticβ-cells activity. Conclusion The findings of this study are of great importance, which confirmed for the first time that treatment of diabetic subjects with silymarin may protect cardiomyocytes against apoptosis and promote survival-restoration of the pancreaticβ-cells.

    Biomarkers are highly specific and sensitive indicators of disease activity. Resistin is a recently discovered adipocytokine, having a potent biomarker quality. Initially resistin was thought to be produced by adipocytes alone; however, emerging evidence suggests that it is also produced in abundance by various cells of the immunoinflammatory system, indicating its role in various chronic inflammatory diseases. Data suggests that resistin plays a role in obesity, insulin resistance, cardiovascular diseases, and periodontitis. Resistin derived its name from the original observation that it induced insulin resistance (resist-in: resist insulin) in mice and is downregulated in mature murine adipocytes cultured in the presence of insulin sensitizing drugs like thiazolidinediones. It is well recognized that obesity, is associated with insulin resistance and diabetes. A three-way relationship has been established between diabetes, obesity and periodontitis. Recent evidence also suggests an association between obesity and increased risk for periodontitis. Our previous research showed incremental elevation of resistin with periodontal disease activity and a reduced level of resistin, after periodontal therapy. Thus resistin would be one of the molecular links connecting obesity, periodontitis, and diabetes and may serve as a marker that links periodontal disease with other systemic diseases. A Medline/PubMed search was carried out for keywords "Diabetes Mellitus," "Periodontitis," and "Resistin," and all relevant research papers from 1990 in English were shortlisted and finalized based on their importance. This review provides an insight into the biological action of resistin and its possible role in periodontitis influenced diabetes mellitus and diabetes induced periodontitis. PMID:24692844

    Full Text Available Objective(s:Painful diabetic neuropathy is associated with hyperexcitability and hyperactivity of spinal cord neurons. However, its underlying pathophysiological mechanisms have not been fully clarified. Induction of excitatory/inhibitory neurotransmission imbalance at the spinal cord seems to account for the abnormal neuronal activity in diabetes. Protective properties of neurosteroids have been demonstrated in numerous cellular and animal models of neurodegeneration. Materials and Methods: Here, the protective effects of allopregnanolone, a neurosteroid were investigated in an in vivo model of diabetic neuropathy. The tail-flick test was used to assess the nociceptive threshold. Diabetes was induced by injection of 50 mg/kg (IP streptozotocin. Seven weeks after the induction of diabetes, the dorsal half of the lumbar spinal cord was assayed for the expression of γ2 subunit of GABAA receptor using semiquantitative RT-PCR. Results: The data shows that allopregnanolone (5 and 20 mg/kg markedly ameliorated diabetes-induced thermal hyperalgesia and motor deficit. The weights of diabetic rats that received 5 and 20 mg/kg allopregnanolone did not significantly reduce during the time course of study. Furthermore, this neurosteroid could inhibit GABAA receptor down-regulation induced by diabetes in the rat spinal cord. Conclusion: The data revealed that allopregnanolone has preventive effects against hyperglycemic-induced neuropathic pain and motor deficit which are related to the inhibition of GABAA receptor down-regulation.

    Diabetes adversely affects reproductive functions in humans and animals. The present study investigated the effects of Resveratrol on diabetes-induced alterations in oxidative stress, c-Jun N-terminal kinase (JNK) signaling and apoptosis in the testis. Adult male Wistar rats (13-15 weeks; n=6/group) were segregated into 1) normal control, 2) Resveratrol-treated (5mg/kg; ip; given during last 3 weeks), 3) Streptozotocin-induced diabetic and, 4) Resveratrol-treated diabetic groups, and euthanized on day 42 after the confirmation of diabetes. Resveratrol did not normalize blood glucose levels in diabetic rats. Resveratrol supplementation recovered diabetes-induced decreases in reproductive organ weights, sperm count and motility, intra-testicular levels of superoxide dismutase, catalase, and glutathione peroxidase and an increase in 4-hydroxynonenal activities (Prats. These results suggest that Resveratrol supplementation may be a useful strategy to treat diabetes-induced testicular dysfunction. PMID:26499206

    Full Text Available Purpose: Ethanol extract of Clitorea ternatea (EECT was evaluated in diabetes-induced cognitive decline rat model for its nootropic and neuroprotective activity. Materials and Methods: Effect on spatial working memory, spatial reference memory and spatial working-reference memory was evaluated by Y maze, Morris water maze and Radial arm maze respectively. Neuroprotective effects of EECT was studied by assaying acetylcholinesterase, lipid peroxide, superoxide dismutase (SOD, total nitric oxide (NO, catalase (CAT and glutathione (GSH levels in the brain of diabetic rats. Results: The EECT (200 and 400 mg/kg was found to cause significant increase in spatial working memory ( P < 0.05, spatial reference memory ( P < 0.001 and spatial working-reference ( P < 0.001 in retention trials on Y maze, Morris water maze and Radial arm maze respectively. Whereas significant decrease in acetylcholinesterase activity ( P < 0.05, lipid peroxide ( P < 0.001, total NO ( P < 0.001 and significant increase in SOD, CAT and GSH levels was observed in animals treated with EECT (200 and 400 mg/kg compared to diabetic control group. Conclusions: The present data indicates that Clitorea ternatea tenders protection against diabetes induced cognitive decline and merits the need for further studies to elucidate its mode of action.

    Male reproductive dysfunctions and infertility are the common consequences of overt diabetes. Available evidence support oxidative stress to be the underlying mechanism for the manifestation of testicular complications during diabetes. In the present study, we assessed the attenuating effects of Withania somnifera root extract (WS) on diabetes-induced testicular oxidative disturbances in prepubertal rats. Four-week-old prepubertal rats were assigned into nondiabetic control, streptozotocin (STZ)-treated and STZ+WS supplemented (500 mg/kg b.w./d, oral, 15 days) groups. Experimental diabetes was induced by a single intraperitoneal injection of STZ (90 mg/kg b.w). Terminally, all animals were killed, and markers of oxidative stress were determined in the testis cytosol and mitochondrial fraction. Severe hyperglycemia and regression in testis size were apparent in diabetic rats. A decline in antioxidant defenses with subsequent elevation in the generation of reactive oxygen species and lipid peroxidation was discernible in testis cytosol and mitochondria of diabetic prepubertal rats, which was significantly reversed by WS. However, there was partial restoration of glucose-6-phosphate dehydrogenase, lactate dehydrogenase, and 3-beta hydroxysteroid dehydrogenase activities in testis of diabetic prepubertal rats administered with WS. Taken together, data accrued suggest the potential of WS to improve diabetes-induced testicular dysfunctions in prepubertal rats. PMID:24488064

    Nitroglycerin (NTG) is an organic nitrate rapidly denitrated by enzymes to release free radical nitric oxide and shows improved wound healing and tissue protection from oxidative damage. The purpose of this study was to evaluate whether topical application of NTG in the form of gel/ointment along with a natural wound healing agent, aloe vera, would bring about wound healing by using diabetes-induced foot ulcer model and rat excision wound model. All these formulations were evaluated for pH, viscosity, drug content and ex vivo diffusion studies using rat skin. Based on ex vivo permeation studies, the formulation consisting of carbopol 974p as a gelling agent and aloe vera was found to be suitable. The in vivo study used streptozotocin-induced diabetic foot ulcer and rat excision wound models to analyse wound healing activity. The wound size in animals of all treated groups was significantly reduced compared with that of the diabetic control and marketed treated animals. This study showed that the gel formed with carbopol 974p (1%) and aloe vera promotes significant wound healing and closure in diabetic rats compared with the commercial product and provides a promising product to be used in diabetes-induced foot ulcer.

    Full Text Available Diabetes mellitus leads to vascular complications but the underlying signalling mechanisms are not fully understood. Here, we examined the role of ErbB2 (HER2/Neu, a transmembrane receptor tyrosine kinase of the ErbB/EGFR (epidermal growth factor receptor family, in mediating diabetes-induced vascular dysfunction in an experimental model of type 1 diabetes. Chronic treatment of streptozotocin-induced diabetic rats (1 mg/kg/alt diem or acute, ex-vivo (10(-6, 10(-5 M administration of AG825, a specific inhibitor of ErbB2, significantly corrected the diabetes-induced hyper-reactivity of the perfused mesenteric vascular bed (MVB to the vasoconstrictor, norephinephrine (NE and the attenuated responsiveness to the vasodilator, carbachol. Diabetes led to enhanced phosphorylation of ErbB2 at multiple tyrosine (Y residues (Y1221/1222, Y1248 and Y877 in the MVB that could be attenuated by chronic AG825 treatment. Diabetes- or high glucose-mediated upregulation of ErbB2 phosphorylation was coupled with activation of Rho kinases (ROCKs and ERK1/2 in MVB and in cultured vascular smooth muscle cells (VSMC that were attenuated upon treatment with either chronic or acute AG825 or with anti-ErbB2 siRNA. ErbB2 likley heterodimerizes with EGFR, as evidenced by increased co-association in diabetic MVB, and further supported by our finding that ERK1/2 and ROCKs are common downstream effectors since their activation could also be blocked by AG1478. Our results show for the first time that ErbB2 is an upstream effector of ROCKs and ERK1/2 in mediating diabetes-induced vascular dysfunction. Thus, potential strategies aimed at modifying actions of signal transduction pathways involving ErbB2 pathway may prove to be beneficial in treatment of diabetes-induced vascular complications.

    Full Text Available Diabetic retinopathy is a leading cause of reduced visual acuity and acquired blindness. Axoglial alterations of the distal (close to the chiasm optic nerve (ON could be the first structural change of the visual pathway in streptozotocin (STZ-induced diabetes in rats. We analyzed the effect of environmental enrichment on axoglial alterations of the ON provoked by experimental diabetes. For this purpose, three days after vehicle or STZ injection, animals were housed in enriched environment (EE or remained in a standard environment (SE for 6 weeks. Anterograde transport, retinal morphology, optic nerve axons (toluidine blue staining and phosphorylated neurofilament heavy immunoreactivity, microglia/macrophages (ionized calcium binding adaptor molecule 1 (Iba-1 immunoreactivity, astrocyte reactivity (glial fibrillary acid protein-immunostaining, myelin (myelin basic protein immunoreactivity, ultrastructure, and brain derived neurotrophic factor (BDNF levels were assessed in non-diabetic and diabetic animals housed in SE or EE. No differences in retinal morphology or retinal ganglion cell number were observed among groups. EE housing which did not affect the STZ-induced weight loss and hyperglycemia, prevented a decrease in the anterograde transport from the retina to the superior colliculus, ON axon number, and phosphorylated neurofilament heavy immunoreactivity. Moreover, EE housing prevented an increase in Iba-1 immunoreactivity, and astrocyte reactivity, as well as ultrastructural myelin alterations in the ON distal portion at early stages of diabetes. In addition, EE housing avoided a decrease in BDNF levels induced by experimental diabetes. These results suggest that EE induced neuroprotection in the diabetic visual pathway.

    Diabetes mellitus is one of the most common causes of neuropathy. Although antioxidant and antidiabetic effects of the aqueous extract of purslane (Portulaca oleracea) (AEOP) have been demonstrated before by other researchers, we did not find any study that assessed the psychobiological effects of AEOP in diabetes induced animals. Thirty ovariectomized (OVX) female Wistar rats were randomly divided into 3 groups of control, Dia and Dia+AEOP. The latter group was orally treated by 300 mg/kg of AEOP for 35 days. Dia and Dia+AEOP groups were made diabetic by IP injection of 60 mg/kg of streptozotocin (STZ). The psychobiological effects of AEOP were assessed by Morris water maze (MWM), elevated plus maze (EPM), forced swimming test (FST) and tail pinch stressor (TPS). AEOP significantly decreased hyperglycemia (pDiabetes significantly decreased their spatial cognitive performance at the training trial as well as the total distance traveled at the probe trial in MWM (pdiabetes related deficits at training trials were improved by AEOP treatment (p0.05). Diabetes significantly increased their non-functional masticatory activity in TPS (p≤0.001) while it was improved in Dia+AEOP group. We showed that AEOP has significant anxiolytic effects and it can improve spatial cognitive performance, locomotor deficit and stress in diabetic OVX rats. PMID:27642327

    Full Text Available KIOM-79, a herbal mixture of parched Puerariae radix, gingered Magnoliae cortex, Glycyrrhizae radix, and Euphorbiae radix, has a strong inhibitory effect on advanced glycation end products (AGEs formation. We investigated the beneficial effects of KIOM-79 on cardiac fibrosis in Zucker diabetic fatty (ZDF rats. KIOM-79 (50 or 500 mg/kg/day was orally administered for 13 weeks. AGEs formation and collagen expression in the myocardium were assessed by immunohistochemistry. The expression levels of the receptor for AGEs (RAGE, transforming growth factor-β1 (TGF-β1, collagen IV, fibronectin, urotensin II, and urotensin II receptor were examined in the myocardial tissue of ZDF rats. KIOM-79 treatment at 500 mg/kg inhibited the accumulation of AGEs, reduced RAGE mRNA and protein expression, and reduced the upregulation of cardiac fibrogenic factors, such as fibronectin and collagen IV, in heart of ZDF rats. Additionally, KIOM-79 ameliorated urotensin II/receptor gene expression in the cardiac tissue of ZDF rats. Our findings indicate that KIOM-79 diminishes cardiac fibrosis in ZDF rats by preventing AGEs accumulation and RAGE overexpression and by modulating the cardiac urotensin II/receptor pathway, which decreases the amount of profibrotic factors, such as TGF-β1, fibronectin, and collagen in cardiac tissue.

    Diabetic cardiomyopathy (DCM) is a significant contributor to the morbidity and mortality associated with diabetes and metabolic syndrome. Retinoids, through activation of retinoic acid receptor (RAR) and retinoid x receptor (RXR), have been linked to control glucose and lipid homeostasis, with effects on obesity and diabetes. However, the functional role of RAR and RXR in the development of DCM remains unclear. Zucker diabetic fatty (ZDF) and lean rats were treated with Am580 (RARα agonist) or LGD1069 (RXR agonist) for 16 weeks, and cardiac function and metabolic alterations were determined. Hyperglycemia, hyperlipidemia and insulin resistance were observed in ZDF rats. Diabetic cardiomyopathy was characterized in ZDF rats by increased oxidative stress, apoptosis, fibrosis, inflammation, activation of MAP kinases and NF-κB signaling and diminished Akt phosphorylation, along with decreased glucose transport and increased cardiac lipid accumulation, and ultimately diastolic dysfunction. Am580 and LGD1069 attenuated diabetes-induced cardiac dysfunction and the pathological alterations, by improving glucose tolerance and insulin resistance; facilitating Akt activation and glucose utilization, and attenuating oxidative stress and interrelated MAP kinase and NF-κB signaling pathways. Am580 inhibited body weight gain, attenuated the increased cardiac fatty acid uptake, β-oxidation and lipid accumulation in the hearts of ZDF rats. However, LGD1069 promoted body weight gain, hyperlipidemia and cardiac lipid accumulation. In conclusion, our data suggest that activation of RAR and RXR may have therapeutic potential in the treatment of diabetic cardiomyopathy. However, further studies are necessary to clarify the role of RAR and RXR in the regulation of lipid metabolism and homeostasis.

    The authors assessed effects of essential fatty acid deficiency (EFAD) on regional {sup 131}I-albumin permeation in diabetic and age-matched control rats. Male, Sprague-Dawley rats (50-75 g) were randomized into EFAD diet or normal diet groups. Three months later, diabetes was induced in one half of the rats in each group by injecting i.v. 35-45 mg/kg b.w. streptozotocin. One month later, {sup 131}I-albumin clearance ({mu} g plasma/g tissue/minute) was assessed as described previously (Circ Res 64;890, 1989). Within controls, EFAD decreased body weight gain 28% but did not affect control values for plasma glucose (118{plus minus}8 (SD) mg/dl) or glycosylated hemoglobin (1.33{plus minus}0.22 % of total hemoglobin). In normal diet and EFAD diabetics, plasma glucose (535{plus minus}64 and 419{plus minus}161, respectively) and glycosylated hemoglobin (4.38{plus minus}0.97 and 2.97{plus minus}1.69) were increased significantly versus controls. Diabetes increased {sup 131}I-albumin clearance in retinal (5.1x controls), choroid (3.4x), anterior uvea (2.7x), aorta (3.5x), and sciatic nerve (2.2x). No differences were evident in tissue {sup 131}I-albumin clearances between both control groups or both diabetic groups. These results suggest that essential fatty acids do not modulate diabetes-induced changes in endothelial cell barrier function.

    Our previous study demonstrated that natriuretic peptides (NPs) play an inhibitory role in regulation of gastric smooth muscle motility. However, it is not clear whether NPs are involved in diabetics-induced loss of gastric interstitial cell of Cajal (ICC). The present study was designed to investigate the relationship between diabetics-induced loss of gastric ICC and natriuretic peptide signaling pathway in streptozotocin (STZ)-induced diabetic mice. The results showed that the protein expression levels of c-Kit and membrane-bound stem cell factor (mSCF) in gastric smooth muscle layers were decreased in STZ-induced diabetic mice. However, both mRNA and protein expression levels of natriuretic peptide receptor (NPR)-A, B and C were increased in the same place of the diabetic mice. The amplitude of spontaneous contraction in gastric antral smooth muscles was inhibited by C-type natriuretic peptide (CNP) dose-dependently and the inhibitory effect was potentiated in diabetic mice. Pretreatment of the cultured gastric smooth muscle cells (GSMCs) with different concentration of CNP can significantly decrease the mSCF expression level. 8-Bromoguanosine-3',5'-cyclomo-nophosphate (8-Br-cGMP), a membrane permeable cGMP analog, mimicked the effect of CNP but not cANF (a specific NPR-C agonist). Methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay showed that high concentration of cANF (10(-6) mol/L) inhibited cell proliferation in cultured GSMCs. These findings suggest that up-regulation of NPs/NPR-A, B/cGMP and NPs/NPR-C signaling pathways may be involved in diabetes-induced loss of gastric ICC.

    Chronic hyperglycemia is associated with impairment of testicular function. The current study aimed to investigate the protective effects and the possible mechanisms of taurine and pioglitazone against diabetes-induced testicular dysfunction in rats. Diabetes was induced by streptozotocin injection. Both normal and diabetic rats received taurine (100 mg/kg) or pioglitazone (10 mg/kg) orally and daily for 6 weeks. Diabetic rats showed a significant (P diabetic rats. Taurine and pioglitazone alleviated hyperglycemia, decreased pro-inflammatory cytokines, and increased circulating levels of insulin, testosterone, LH, and FSH. Gene and protein expression of LH and FSH receptors and cytochrome P450 17α-hydroxylase (CYP17) was significantly (P diabetic rats, an effect which was significantly increased after administration of taurine and pioglitazone. In addition, taurine and pioglitazone significantly decreased lipid peroxidation and DNA damage, and enhanced activity of the antioxidant enzymes in testes of diabetic rats. In conclusion, taurine and pioglitazone exerted protective effects against diabetes-induced testicular damage through attenuation of hyperglycemia, inflammation, oxidative stress and DNA damage, and up-regulation of the pituitary/gonadal axis.

    We hypothesized that in vitro treatment of peripheral blood mononuclear cells (PB-MNCs) from diabetic patients with ephrin-B2/Fc (EFNB2) improves their proangiogenic therapeutic potential in diabetic ischemic experimental models. Diabetes was induced in nude athymic mice by streptozotocin injections. At 9 weeks after hyperglycemia, 105 PB-MNCs from diabetic patients, pretreated by EFNB2, were intravenously injected in diabetic mice with hindlimb ischemia. Two weeks later, the postischemic neovascularization was evaluated. The mechanisms involved were investigated by flow cytometry analysis and in vitro cell biological assays. Paw skin blood flow, angiographic score, and capillary density were significantly increased in ischemic leg of diabetic mice receiving EFNB2-activated diabetic PB-MNCs versus those receiving nontreated diabetic PB-MNCs. EFNB2 bound to PB-MNCs and increased the adhesion and transmigration of PB-MNCs. Finally, EFNB2-activated PB-MNCs raised the number of circulating vascular progenitor cells in diabetic nude mice and increased the ability of endogenous bone marrow MNCs to differentiate into cells with endothelial phenotype and enhanced their proangiogenic potential. Therefore, EFNB2 treatment of PB-MNCs abrogates the diabetes-induced stem/progenitor cell dysfunction and opens a new avenue for the clinical development of an innovative and accessible strategy in diabetic patients with critical ischemic diseases.

    Full Text Available Type 2 diabetes mellitus (T2DM significantly increases risk for vascular complications. Diabetes-induced aorta pathological changes are predominantly attributed to oxidative stress. Nuclear factor E2-related factor-2 (Nrf2 is a transcription factor orchestrating antioxidant and cytoprotective responses to oxidative stress. Sulforaphane protects against oxidative damage by increasing Nrf2 expression and its downstream target genes. Here we explored the protective effect of sulforaphane on T2DM-induced aortic pathogenic changes in C57BL/6J mice which were fed with high-fat diet for 3 months, followed by a treatment with streptozotocin at 100 mg/kg body weight. Diabetic and nondiabetic mice were randomly divided into groups with and without 4-month sulforaphane treatment. Aorta of T2DM mice exhibited significant increases in the wall thickness and structural derangement, along with significant increases in fibrosis (connective tissue growth factor and transforming growth factor, inflammation (tumor necrosis factor-α and vascular cell adhesion molecule 1, oxidative/nitrative stress (3-nitrotyrosine and 4-hydroxy-2-nonenal, apoptosis, and cell proliferation. However, these pathological changes were significantly attenuated by sulforaphane treatment that was associated with a significant upregulation of Nrf2 expression and function. These results suggest that sulforaphane is able to upregulate aortic Nrf2 expression and function and to protect the aorta from T2DM-induced pathological changes.

    Diabetes-associated cognitive dysfunction, referred as "diabetic encephalopathy", has been confirmed in a great deal of literature. Current evidence support that oxidative stress, inflammation, energy metabolism imbalance, and aberrant insulin signaling are associated with cognition deficits induced by diabetes. The present study explore the effect of asiaticoside on the cognition behaviors, synapses, and oxidative stress in diabetic rats. Asiaticoside could markedly ameliorate the performance in the Morris Water Maze (decreased latency time and path length, and increased time spent in the target quadrant), which was correlated with its capabilities of suppressing oxidative stress, restoring Na(+)-K(+)-ATPase activity and protecting hippocampal synapses. In vitro, asiaticoside could up-regulate synaptic proteins expression via modulating Phosphoinositide 3-kinase (PI3K)/Protein Kinase B(AKT)/Nuclear Factor -kappa B (NF-κB)-mediated inflammatory pathway in SH-SY5Y cells incubated with high glucose chronically. In conclusion, asiaticoside had beneficial effects on the prevention and treatment of diabetes-associated cognitive deficits, which was involved in oxidative stress, PI3K/Akt/NF-κB pathway and synaptic function in the development of cognitive decline induced by diabetes.

    Full Text Available Gelidium amansii (GA is an edible red algae that is distributed mainly in northeastern Taiwan. This study was designed to investigate the effects of GA on plasma glucose, lipids, and adipocytokines in rats with streptozotocin-nicotinamide-induced diabetes. Rats were divided into four groups: (1 rats without diabetes fed a high-fat diet (control group; (2 rats with diabetes fed a high-fat diet; (3 rats with diabetes fed a high-fat diet with thiazolidinedione in the diet; and (4 rats with diabetes fed a high-fat diet and GA. The experimental diet and drinking water were available ad libitum for 11 weeks. After the 11-week feeding study, plasma glucose, triglyceride, and cholesterol concentrations were lower in rats with diabetes fed the GA diet than in animals with diabetes fed the control diet. In addition, cholesterol and triglyceride excretion were significantly higher in rats with diabetes fed the GA diet. Moreover, GA feeding induced lipolysis in both paraepididymal and perirenal adipose tissues. Adipose tissue (paraepididymal and perirenal weight and triglyceride contents were lower after GA treatment. Plasma adipocytokines including tumor necrosis factor-alpha, interleukin-6, and plasminogen activator inhibitor-1 were reduced by GA feeding in rats with diabetes. The results of the current study suggest that GA feeding may regulate plasma glucose and lipid levels and prevent adipose tissue accumulation in rats with diabetes.

    This study investigated the effects of resveratrol (RSV) on retinal functions, glutamate transporters (GLAST) and glutamine synthetase (GS) expression in diabetic rats retina, and on glutamate uptake, GS activity, GLAST and GS expression in high glucose-cultured Müller cells. The electroretinogram was used to evaluate retinal functions. Müller cells cultures were prepared from 5- to 7-day-old Sprague-Dawley rats. The expression of GLAST and GS was examined by qRT-PCR, ELISA and western-blotting. Glutamate uptake was measured as (3)H-glutamate contents of the lysates. GS activity was assessed by a spectrophotometric assay. 1- to 7-month RSV administrations (5 and 10 mg/kg/day) significantly alleviated hyperglycemia and weight loss in diabetic rats. RSV administrations also significantly attenuated diabetes-induced decreases in amplitude of a-wave in rod response, decreases in amplitude of a-, and b-wave in cone and rod response and decreases in amplitude of OP2 in oscillatory potentials. 1- to 7-month RSV treatments also significantly inhibited diabetes-induced delay in OP2 implicit times in scotopic 3.0 OPS test. The down-regulated mRNA and protein expression of GLAST and GS in diabetic rats retina was prevented by RSV administrations. In high glucose-treated cultures, Müller cells' glutamate uptake, GS activity, GLAST and GS expression were decreased significantly compared with normal control cultures. RSV (10, 20, and 30 mmol/l) significantly inhibited the HG-induced decreases in glutamate uptake, GS activity, GLAST and GS expression (at least P < 0.05). These beneficial results suggest that RSV may be considered as a therapeutic option to prevent from diabetic retinopathy.

    Diabetic encephalopathy is one of the most prevalent chronic complications of diabetes mellitus (DM), but there is currently no effective method of prevention nor proven therapeutic regimen for it. In this study, we investigated the effects of calycosin on cognitive behavior and the potential mechanism involved in streptozocin-induced diabetic rats. The effects of diabetes and calycosin treatment on spatial learning and memory were evaluated using the Morris Water Maze, passive avoidance and motor coordination tests. Histological analysis of the hippocampus cornu ammonis 1 (CA1) region was conducted in rats. The decreased expression of the synapsin (SYN) and postsynatptic density protein (PSD-95), as well as brain-derived neurotrophic factor (BDNF) in diabetic rats was measured by quantitative real-time PCR and western blot. Treatment with calycosin promoted a reduction in the expression of SYN, PSD-95 and BDNF. In addition, diabetic rats showed increased MDA levels, and decreased SOD levels and GSH-Px activities in the hippocampus, as well as increased AChE activity in the cerebral cortex; these changes were reversed by calycosin supplementation. Thus, the impairment of learning and memory in STZ-induced diabetic rats was alleviated by calycosin, and that the degree of alleviation was associated with oxidative stress. We also found that calycosin treatment significantly stimulated Akt phosphorylation and decreased GSK-3β and tau phosphorylation, and that these changes could be restored by the PI3K/Akt inhibitor LY294002. In conclusion, calycosin had a beneficial effect on the amelioration, prevention and treatment of diabetes-associated cognitive deficits, through its involvement in oxidative stress, synaptic function and the PI3K/Akt/GSK-3β pathway.

    Among the diabetic complications, diabetic foot ulcer due to delayed wound healing is one of the most significant clinical problems. Early inflammatory stage is important for better prognosis during wound healing. Thus, regulation of inflammatory response during early stage of wound healing is main target for complete cutaneous recovery. This study investigated the role of genistein supplementation in inflammation and oxidative stress, which are related to NLRP3 inflammasome, NFκB and Nrf2 activation, during cutaneous wound healing in alloxan-induced diabetic mice. Mice with diabetes with fasting blood glucose (FBG) levels > 250 mg/dl were fed diets with AIN-93G rodent diet containing 0%, 0.025% (LG) or 0.1% (HG) genistein. After 2 weeks of genistein supplementation, excisional wounds were made by biopsy punches (4 mm). Genistein supplementation improved fasting glucose levels and wound closure rate. Moreover, genistein supplementation restored NLRP3 inflammasome (NLRP3, ASC and caspase-1) at the basal level and ameliorated both inflammation (TNFα, iNOS, COX2 and NFκB) and antioxidant defense system (Nrf2, HO-1, GPx, and catalase) during early stage of wound healing in diabetic mice. Taken together, genistein supplementation would be a potential therapeutic nutrient in prevention and treatment of delayed wound healing by modulation of inflammation and oxidative stress during inflammatory stage.

    Diabetic nephropathy (DN) is the leading cause of end-stage renal failure and is characterized by excessive deposition of extracellular matrix (ECM) proteins such as fibronectin (FN), in the glomerular mesangium and tubulointerstitium. Betulinic acid (BA), a pentacyclic triterpene derived from the bark of the white birch tree, has been demonstrated to have many pharmacological activities. However, the effect of BA on DN has not been fully elucidated. To explore the possible anti-inflammatory effects of BA and their underlying mechanisms, we used streptozotocin-induced diabetic rat kidneys and high glucose-treated glomerular mesangial cells. Our study showed BA could inhibit the degradation of IκBα and the activity of NF-κB in diabetic rat kidneys and high glucose-induced mesangial cells, resulting in reduction of FN expression. In addition, BA suppressed the DNA binding activity and transcriptional activity of NF-κB in high glucose-induced glomerular mesangial cells (GMCs). Furthermore, BA enhanced the interaction between IκBα and β-arrestin2 in mesangial cells. Taken together, our data suggest BA inhibits NF-κB activation through stabilizing NF-κB inhibitory protein IκBα, thereby preventing diabetic renal fibrosis. PMID:27364889

    Full Text Available Introduction: Diabetes mellitus is one of the most prevalent chronic and complex metabolic diseases of human , which hyperglycemia can be mentioned as its prominent characteristic. Therefore, this study aimed to evaluate the hypoglycemic effects of fruit of Rosa canina (R.c. extract in healthy and diabetic rats. Method: A total of 72 Wistar male rats were divided into six group: control,  STZ (diabetic control,  R.c. control (50 mg/kg, R.c. control (100 mg/kg and two experimental groups with 50, and 100 mg/kg of extract dose. Diabetes was induced using streptozotocine (60 mg/kg; IP, and blood collection was carried out on 0, 2 and 4 hours after the oral administration of the extracts. Results: The levels of plasma glucose were determined by spectrophotometric method. In order to statistically analyze the study data, ANOVA test was performed. There was a significant difference between groups concerning the plasma glucose concentration (P<0.0001, which the lowest concentration between diabetes groups was observed in the two experimental groups. Moreover, R.c. had a marked hypoglycemic effect on diabetes mellitus. Conclusion: R.c. extract in hyperglycemic status demands to be further studied in order to control and prevent its complications.

  7. Deletion of Protein Tyrosine Phosphatase 1B (PTP1B Enhances Endothelial Cyclooxygenase 2 Expression and Protects Mice from Type 1 Diabetes-Induced Endothelial Dysfunction.

    Directory of Open Access Journals (Sweden)

    David J Herren

    Full Text Available Protein tyrosine phosphatase 1B (PTP1B dephosphorylates receptors tyrosine kinase and acts as a molecular brake on insulin signaling pathway. Conditions of metabolic dysfunction increase PTP1B, when deletion of PTP1B protects against metabolic disorders by increasing insulin signaling. Although vascular insulin signaling contributes to the control of glucose disposal, little is known regarding the direct role of PTP1B in the control of endothelial function. We hypothesized that metabolic dysfunctions increase PTP1B expression in endothelial cells and that PTP1B deletion prevents endothelial dysfunction in situation of diminished insulin secretion. Type I diabetes (T1DM was induced in wild-type (WT and PTP1B-deficient mice (KO with streptozotocin (STZ injection. After 28 days of T1DM, KO mice exhibited a similar reduction in body weight and plasma insulin levels and a comparable increase in glycemia (WT: 384 ± 20 vs. Ko: 432 ± 29 mg/dL, cholesterol and triglycerides, as WT mice. T1DM increased PTP1B expression and impaired endothelial NO-dependent relaxation, in mouse aorta. PTP1B deletion did not affect baseline endothelial function, but preserved endothelium-dependent relaxation, in T1DM mice. NO synthase inhibition with L-NAME abolished endothelial relaxation in control and T1DM WT mice, whereas L-NAME and the cyclooxygenases inhibitor indomethacin were required to abolish endothelium relaxation in T1DM KO mice. PTP1B deletion increased COX-2 expression and PGI2 levels, in mouse aorta and plasma respectively, in T1DM mice. In parallel, simulation of diabetic conditions increased PTP1B expression and knockdown of PTP1B increased COX-2 but not COX-1 expression, in primary human aortic endothelial cells. Taken together these data indicate that deletion of PTP1B protected endothelial function by compensating the reduction in NO bioavailability by increasing COX-2-mediated release of the vasodilator prostanoid PGI2, in T1DM mice.

    Learning and memory impairment occurs in diabetes. Salvia officinalis L. (SO) has been used in Iranian traditional medicine as a remedy against diabetes. We hypothesized that chronic administration of SO (400, 600 and 800mg/kg, p.o.) and its principal constituent, rosmarinic acid, would affect on passive avoidance learning (PAL) and memory in streptozocin-induced diabetic and non-diabetic rats. We also explored hypoglycemic and antioxidant activities of SO as the possible mechanisms. Treatments were begun at the onset of hyperglycemia. PAL was assessed 30days later. Retention test was done 24h after training. At the end, animals were weighed and blood samples were drawn for further analyzing of glucose and oxidant/antioxidant markers. Diabetes induced deficits in acquisition and retrieval processes. SO (600 and 800mg/kg) and rosmarinic acid reversed learning and memory deficits induced by diabetes and improved cognition of healthy rats. While the dose of 400mg/kg had no effect, the higher doses and rosmarinic acid inhibited hyperglycemia and lipid peroxidation as well as enhanced the activity of antioxidant enzymes superoxide dismutase and catalase. SO prevented diabetes-induced acquisition and memory deficits through inhibiting hyperglycemia, lipid peroxidation as well as enhancing antioxidant defense systems. Therefore, SO and its principal constituent rosmarinic acid represent a potential therapeutic option against diabetic memory impairment which deserves consideration and further examination.

  10. Preventive maintenance

    International Nuclear Information System (INIS)

    The information contained in this paper should be used in conjunction with the maintenance instructions provided by the manufacturer of each valve. When there is any question or conflict between the procedure described and the manufacturer's, the author suggests determining the best method for the applications. A good long range preventative maintenance program for valves will eliminate costly repairs or replacement of valves long before their time. A little flush, lube, and what was once called elbow grease will also go a long way in reducing your downtime and maintenance budget. This paper will discuss one of the most misunderstood theories concerning valve maintenance, i.e., that periodic maintenance of valves includes the injection of sealants. Sealants are injected into valves as a secondary seal for most valves. Under normal conditions, valves do not require sealant injection. Solid fillers in sealants tend to plug the system making it virtually impossible to inject either sealant or a lubricant, requiring the injection of flush or cleaners to dislodge the solids. Topics covered in this paper will range from general maintenance requirements to valve flushing, cleaning and lubrication

    To develop a clinic-relevant protocol for systemic up-regulation of NFE2-related factor 2 (Nrf2) to prevent diabetic cardiomyopathy (DCM), male db/db and age-matched wild-type (WT) mice were given sulforaphane (SFN, an Nrf2 activator) and its natural source, broccoli sprout extract (BSE) by gavage every other day for 3 months, with four groups: vehicle (0.1 ml/10 g), BSE-low dose (estimated SFN availability at 0.5 mg/kg), BSE-high dose (estimated SFN availability at 1.0 mg/kg), and SFN (0.5 mg/kg). Cardiac function and pathological changes (hypertrophy, fibrosis, inflammation and oxidative damage) were assessed by echocardiography and histopathological examination along with Western blot and real-time PCR, respectively. Both BSE and SFN significantly prevented diabetes-induced cardiac dysfunction, hypertrophy and fibrosis. Mechanistically, BSE, like SFN, significantly up-regulated Nrf2 transcriptional activity, evidenced by the increased Nrf2 nuclear accumulation and its downstream gene expression. This resulted in a significant prevention of cardiac oxidative damage and inflammation. For all these preventive effects, BSE at high dose provided a similar effect as did SFN. These results indicated that BSE at high dose prevents DCM in a manner congruent with SFN treatment. Therefore, it suggests that BSE could potentially be used as a natural and safe treatment against DCM via Nrf2 activation. PMID:27457280

    The argan tree plays an important socioeconomic and ecologic role in South Morocco. Moreover, there is much evidence for the beneficial effects of virgin argan oil (VAO) on human health. Thus, this study investigated whether administering VAO to rats can prevent the development of diabetes. VAO extracted by a traditional method from the almonds of Argania spinosa (2 mL/kg) was administered orally (for 7 consecutive days) to rats before and during intraperitoneal alloxan administration (75 mg/kg for 5 consecutive days). An alloxan diabetic-induced untreated group and treated by table oil were used as control groups. Body mass, blood glucose and hepatic glycogen were evaluated. In the present study, subchronic treatment with VAO at a dose of 2 mL/kg, before the experimental induction of diabetes, prevented the body mass loss, induced a significant reduction of blood glucose and a significant increase of hepatic glycogen level (p argan oil should be further investigated in a human study to clarify its possible role in reducing weight loss in diabetics, and even in inhibiting the development or progression of diabetes. This antidiabetic effect could be due to the richness of VAO in tocopherols, phenolic compounds and unsaturated fatty acids.

    The dementia prevention consists of three steps, primary prevention of dementia is to prevent from normal and mild cognitive impairment to dementia, secondary prevention is early detection and early treatment of dementia, and tertiary prevention is three stages of progress prevention of dementia. Primary prevention of dementia had been considered impossible until recently, but potential scientific evidence has been shown recently. The fact that 4.62 million people are person with dementia and 400 million people are person with mild cognitive impairment are considered to be urgent problem and we must intend to perform dementia prevention from primary to tertiary prevention thoroughly. We perform dementia screening using touch panel type computer and we recommend person with mild cognitive impairment to join dementia prevention classroom. Therefore, we can prevent progression from mild cognitive impairment to dementia (primary prevention). Early diagnosis and introduction to the specialized medical institution are needed if you find early stage of dementia and treat early (secondary prevention). To prevent progression by the appropriate drug treatment and care for dementia is required (tertiary prevention).

    Full Text Available This study aimed to evaluate the efficacy of sitagliptin, a dipeptidyl peptidase IV (DPP-IV inhibitor, in preventing the deleterious effects of diabetes on the kidney in an animal model of type 2 diabetes mellitus; the Zucker diabetic fatty (ZDF rat: 20-week-old rats were treated with sitagliptin (10 mg/kg bw/day during 6 weeks. Glycaemia and blood HbA1c levels were monitored, as well as kidney function and lesions. Kidney mRNA and/or protein content/distribution of DPP-IV, GLP-1, GLP-1R, TNF-α, IL-1β, BAX, Bcl-2, and Bid were evaluated by RT-PCR and/or western blotting/immunohistochemistry. Sitagliptin treatment improved glycaemic control, as reflected by the significantly reduced levels of glycaemia and HbA1c (by about 22.5% and 1.2%, resp. and ameliorated tubulointerstitial and glomerular lesions. Sitagliptin prevented the diabetes-induced increase in DPP-IV levels and the decrease in GLP-1 levels in kidney. Sitagliptin increased colocalization of GLP-1 and GLP-1R in the diabetic kidney. Sitagliptin also decreased IL-1β and TNF-α levels, as well as, prevented the increase of BAX/Bcl-2 ratio, Bid protein levels, and TUNEL-positive cells which indicates protective effects against inflammation and proapoptotic state in the kidney of diabetic rats, respectively. In conclusion, sitagliptin might have a major role in preventing diabetic nephropathy evolution due to anti-inflammatory and antiapoptotic properties.

    Angiotensin-(1-7) [Ang-(1-7)] may have beneficial effects in diabetes mellitus-induced erectile dysfunction (DMIED) but its molecular actions in the diabetic corpus cavernosum (CC) are not known. We characterized the effects of diabetes and/or chronic in vivo administration of Ang-(1-7) on vascular reactivity in the rat corpus cavernosum (CC) and on protein expression levels of potential downstream effectors of the renin-angiotensin-aldosterone system (RAAS) such as angiotensin-converting enzyme (ACE), ACE2, Rho kinases 1 and 2 (ROCK1 and ROCK2), and omega-hydroxylase, the cytochrome-P450 enzyme that metabolizes arachidonic acid to form the vasoconstrictor, 20-hydroxyeicosatetraenoic acid. Streptozotocin-treated rats were chronicically administered Ang-(1-7) with or without A779, a Mas receptor antagonist, during weeks 4 to 6 of diabetes. Ang-(1-7) reversed diabetes-induced abnormal reactivity to vasoactive agents (endothelin-1, phenylepherine, and carbachol) in the CC without correcting hyperglycemia. Six weeks of diabetes led to elevated ACE, ROCK1, ROCK 2, and omega-hydroxylase and a concomitant decrease in ACE2 protein expression levels that were normalized by Ang-(1-7) treatment but not upon coadministration of A779. These data are supportive of the notion that the beneficial effects of Ang-(1-7) in DMIED involve counterregulation of diabetes-induced changes in ACE, ACE2, Rho kinases, and omega-hydroxylase proteins in the diabetic CC via a Mas receptor-dependent mechanism.

  15. Preventing Diabetes: Early Versus Late Preventive Interventions.

    Science.gov (United States)

    Tuomilehto, Jaakko; Schwarz, Peter E H

    2016-08-01

    There are a number of arguments in support of early measures for the prevention of type 2 diabetes (T2D), as well as for concepts and strategies at later intervention stages. Diabetes prevention is achievable when implemented in a sustainable manner. Sustainability within a T2D prevention program is more important than the actual point in time or disease process at which prevention activities may start. The quality of intervention, as well as its intensity, should vary with the degree of the identified T2D risk. Nevertheless, preventive interventions should start as early as possible in order to allow a wide variety of relatively low- and moderate-intensity programs. The later the disease risk is identified, the more intensive the intervention should be. Public health interventions for diabetes prevention represent an optimal model for early intervention. Late interventions will be targeted at people who already have significant pathophysiological derangements that can be considered steps leading to the development of T2D. These derangements may be difficult to reverse, but the worsening of dysglycemia may be halted, and thus the clinical onset of T2D can be delayed. PMID:27440823

  16. Alendronate Can Improve Bone Alterations in Experimental Diabetes by Preventing Antiosteogenic, Antichondrogenic, and Proadipocytic Effects of AGEs on Bone Marrow Progenitor Cells

    Directory of Open Access Journals (Sweden)

    Sara Rocío Chuguransky

    2016-01-01

    Full Text Available Bisphosphonates such as alendronate are antiosteoporotic drugs that inhibit the activity of bone-resorbing osteoclasts and secondarily promote osteoblastic function. Diabetes increases bone-matrix-associated advanced glycation end products (AGEs that impair bone marrow progenitor cell (BMPC osteogenic potential and decrease bone quality. Here we investigated the in vitro effect of alendronate and/or AGEs on the osteoblastogenic, adipogenic, and chondrogenic potential of BMPC isolated from nondiabetic untreated rats. We also evaluated the in vivo effect of alendronate (administered orally to rats with insulin-deficient Diabetes on long-bone microarchitecture and BMPC multilineage potential. In vitro, the osteogenesis (Runx2, alkaline phosphatase, type 1 collagen, and mineralization and chondrogenesis (glycosaminoglycan production of BMPC were both decreased by AGEs, while coincubation with alendronate prevented these effects. The adipogenesis of BMPC (PPARγ, intracellular triglycerides, and lipase was increased by AGEs, and this was prevented by coincubation with alendronate. In vivo, experimental Diabetes (a decreased femoral trabecular bone area, osteocyte density, and osteoclastic TRAP activity; (b increased bone marrow adiposity; and (c deregulated BMPC phenotypic potential (increasing adipogenesis and decreasing osteogenesis and chondrogenesis. Orally administered alendronate prevented all these Diabetes-induced effects on bone. Thus, alendronate could improve bone alterations in diabetic rats by preventing the antiosteogenic, antichondrogenic, and proadipocytic effects of AGEs on BMPC.

  17. Prevention Of Stroke

    Directory of Open Access Journals (Sweden)

    Nagaraja D

    2005-01-01

    Full Text Available Stroke is an important cause for neurological morbidity and mortality. Prevention of ischemic stroke involves identification and prevention of risk factors and optimal use of pharmacotherapy. Risk factors have been classified as modifiable and non-modifiable; control of modifiable factors should prevent stroke occurrence. Stroke prevention has been described at three levels: primary, secondary and tertiary. Prolonged hypertension increases an individual′s risk for developing fatal or nonfatal stroke by three times and its control has been shown to prevent stroke. Diabetes mellitus is an important cause for microangiopathy and predisposes to stroke. Statin trials have shown significant reduction in stroke in those who were treated with statins. Stroke risk can be reduced by avoiding tobacco use, control of obesity and avoiding sedentary life style. Anti platelet medications are effective for secondary prevention of stroke. Educating society regarding modifiable risk factors and optimal use of pharmacotherapy form the cornerstone for the prevention of stroke.

    2012-06-01

    Smoking is the most important risk factor for the occurrence/progression of Graves' ophthalmopathy (GO), as well as for its lower/slower response to immunosuppression. Accordingly, refrain from smoking should be urged, both as primary prevention (removal of risk factors in Graves' patients without GO), secondary prevention (early detection and treatment of asymptomatic/very mild GO) and tertiary prevention (reduction of complications/disability of overt GO). A 6-month course of 200 μg/day sodium selenite can prevent progression of mild GO to more severe GO and is, therefore, a form of secondary prevention and, probably, primary prevention. Correction of thyroid dysfunction and stable maintenance of euthyroidism are important preventive measures. The optimal treatment for hyperthyroidism in patients with GO is uncertain, because evidence demonstrating the superiority of antithyroid drugs over thyroid ablation (radioiodine, thyroidectomy, or both) is lacking. If radioiodine is used, low-dose steroid prophylaxis is recommended, particularly in smokers, to prevent radioiodine-associated GO progression. PMID:22632372

  13. Prevention of preterm birth.

    LENUS (Irish Health Repository)

    Flood, Karen

    2012-02-01

    Preterm birth (delivery before 37 completed weeks of gestation) is common and rates are increasing. In the past, medical efforts focused on ameliorating the consequences of prematurity rather than preventing its occurrence. This approach resulted in improved neonatal outcomes, but it remains costly in terms of both the suffering of infants and their families and the economic burden on society. Increased understanding of the pathophysiology of preterm labor has altered the approach to this problem, with increased focus on preventive strategies. Primary prevention is a limited strategy which involves public education, smoking cessation, improved nutritional status and avoidance of late preterm births. Secondary prevention focuses on recurrent preterm birth which is the most recognisable risk factor. Widely accepted strategies include cervical cerclage, progesterone and dedicated clinics. However, more research is needed to explore the role of antibiotics and anti-inflammatory treatments in the prevention of this complex problem.

    2015-01-01

    With the exception of cardiovascular diseases, no other medical condition causes more serious dysfunction or premature deaths than alcohol-related problems. Research results indicate that alcohol dependent individuals present an exceptionally poor level of quality of life. This is an outcome that highlights the necessity of planning and implementing preventive interventions on biological, psychological or social level, to be provided to individuals who make alcohol abuse, as well as to their families. Preventive interventions can be considered on three levels of prevention: (a) primary prevention, which is focused on the protection of healthy individuals from alcohol abuse and dependence, and may be provided on a universal, selective or indicated level, (b) secondary prevention, which aims at the prevention of deterioration regarding alcoholic dependence and relapse, in the cases of individuals already diagnosed with the condition and (c) tertiary prevention, which is focused at minimizing deterioration of functioning in chronically sufferers from alcoholic dependence. The term "quaternary prevention" can be used for the prevention of relapse. As for primary prevention, interventions focus on assessing the risk of falling into problematic use, enhancing protective factors and providing information and health education in general. These interventions can be delivered in schools or in places of work and recreation for young people. In this context, various programs have been applied in different countries, including Greece with positive results (Preventure, Alcolocks, LST, SFP, Alcohol Ignition Interlock Device). Secondary prevention includes counseling and structured help with the delivery of programs in schools and in high risk groups for alcohol dependence (SAP, LST). These programs aim at the development of alcohol refusal skills and behaviors, the adoption of models of behaviors resisting alcohol use, as well as reinforcement of general social skills. In the

    Full Text Available Life style factors are contributing significantly in cancer prevention. With the intake of proper and balanced diet ,cancer prevention is possible. Many foods are associated either with incidence or prevention of cancer. Plant based foods like fresh fruits, vegetables and whole grains rich in fiber, b-carotene, vitamins and antioxidants can prevent cancer. Fiber rich foods increase bowel movement, decreasing the absorption of cholesterol. Pumpkin, carrots contain b-carotenes. Leafy vegetables, broccoli, cabbage, cauliflower, peas and beans are rich in fiber and stimulate cancer preventing enzyme induction. Vitamin C rich citrus fruits can stimulate immune system. Garlic and onions can stimulate enzymes that can suppress tumor growth. Turmeric used in cooking can prevent colorectal cancer. Topical application of turmeric can prevent breast cancer in women. On the other hand, certain foods can cause cancer. Refined foods, high fat foods, deep fried foods, processed foods and low fiber foods increase cancer risk. Red meat, processed meat and barbeques contain a carcinogen called acrylamide. Foods prepared with hydrogenated fats contain transfats which increase risk for breast, ovarian, cervical and lung cancer. Consumption of alcohol increasing the risk for cancers of digestive system.

    2016-07-01

    Lipohypertrophy is an important insulin injection site reaction, which has clinically significant sequelae, including a greater risk of glycaemic variability and higher insulin dose requirement. This article describes the prevention of lipohypertrophy, using the concept of levels of prevention. It enumerates methods of primordial, primary, secondary, tertiary and quaternary prevention of lipohypertrophy. Focus on patient education, site rotation, avoidance of needle reuse, and dose titration when shifting from injection in lipohypertrophic lesions to normal subcutaneous tissue, helps minimize the development and impact of lipohypertrophy.

    Vértes, András; Szabados, Eszter

    2016-09-01

    Cardiovascular diseases are the main causes of premature death worldwide despite the fact that cardiovascular mortality decreased significantly in the last few decades in financially developed countries. This reduction is partly due to the modern medical and revascularisation treatments, and partly because of the effectiveness of prevention strategies such as lowering blood pressure and cholesterol level, as well as successful strategies against smoking. However, this positive trend is undermined by the striking growth in obesity and in type 2 diabetes mellitus, which could also be successfully controlled by lifestyle changes. This summary is based on an overview of the recent (2016) European Guideline for the Prevention of Cardiovascular Diseases. Here the authors describe preventive strategies and goals to be achieved, the most important lifestyle suggestions, and the secondary prevention medical treatment for patients with already established cardiovascular disease.

    2016-01-01

    The number of patients undergoing hematopoietic cell and solid organ transplantation are increasing every year, as are the number of centers both transplanting and caring for these patients. Improvements in transplant procedures, immunosuppressive regimens, and prevention of transplant-associated complications have led to marked improvements in survival in both populations. Infections remain one of the most important sources of excess morbidity and mortality in transplant, and therefore, infection prevention strategies are a critical element for avoiding these complications in centers caring for high-risk patients. This manuscript aims to provide an update of recent data on prevention of major healthcare-associated infections unique to transplantation, reviews the emergence of antimicrobial resistant infections, and discusses updated strategies to both identify and prevent transmission of these pathogens in transplant recipients.

  9. Prevention of cisplatin nephrotoxicity

    Directory of Open Access Journals (Sweden)

    Hayati Fatemeh

    2016-01-01

    Full Text Available Cisplatin has a well-established role in the treatment of broad spectrum of malignancies; however its use is limited because of cisplatin-induced nephrotoxicity (CIN which can be progressive in more than 50% of cases. The most important risk factors for CIN include higher doses of cisplatin, previous cisplatin chemotherapy, underlying kidney damage and concurrent treatment with other potential nephrotoxin agents, such as aminoglycosides, nonsteroidal anti-inflammatory agents, or iodinated contrast media. Different strategies have been offered to diminish or prevent nephrotoxicity of cisplatin. The standard approach for prevention of CIN is the administration of lower doses of cisplatin in combination with full intravenous hydration prior and after cisplatin administration. Cisplatin-induced oxidative stress in the kidney may be prevented by natural antioxidant compounds. The results of this review show that many strategies for prevention of CIN exist, however, attention to the administration of these agent for CIN is necessary.

    Science.gov (United States)

    Kew, Michael C

    2010-01-01

    Because of its frequency and grave prognosis, preventing hepatocellular carcinoma is an urgent priority. Prevention should be possible because environmental carcinogens-chronic hepatitis B and C virus infections, dietary exposure to aflatoxins, and iron overload-cause the great majority of these tumors. Chronic hepatitis B virus infection accounts for 55% of global hepatocellular carcinomas and 80% of those in the high-incidence Asia Pacific and sub-Saharan African regions. In these regions the infection that becomes chronic is predominantly acquired very early in life. A safe and effective vaccine against this virus is available and its universal inclusion in the immunization of infants has already resulted in a marked reduction of chronic infection and a 70% decrease in the occurrence of hepatocellular carcinoma in those immunized. Chronic hepatitis C virus infection is the major cause of hepatocellular carcinoma in industrialized countries. The infection is mainly acquired in adulthood and, until a vaccine becomes available, prevention will consist mainly of identifying, counselling, and treating chronically infected individuals, preventing spread of the virus by the use of safe injection practices (particularly in intravenous drug abusers), and screening all donated blood for the presence of the virus. 4.5 billion of the world.s population are exposed to dietary aflatoxins. Prevention involves treating susceptible crops to prevent fungal contamination, and handling the foodstuffs in such a way as to prevent contamination during storage. Iron overload in hereditary hemochromatosis can be prevented by repeated venesection and in African dietary iron overload by fermenting the home-brewed beer in iron-free containers. PMID:20526004

    Development of a food allergy appears to depend on both genetic factors and exposure-especially in early infancy-to food proteins. In prospective studies, the effect of dietary allergy prevention programmes has only been demonstrated in high-risk infants, i.e. infants with at least one first degree...... relative with documented atopic disease. High-risk infants feeding exclusively on breast milk and/or extensively hydrolysed formula (eHF) combined with avoidance of cow's milk proteins and solid foods during at least the first 4 months of life are found to have a significant reduction in the cumulative...... incidence of food allergy, especially cow's milk protein allergy/intolerance (CMPA/CMPI), in the first 4 years of life. As no studies have been conducted pertaining to the preventive effect of avoidance of milk and other foods after the age of 4-6 months, recommendation of preventive elimination diets...

    Jensen, J Daniel; Wing, Gregory J; Dellavalle, Robert P

    2010-01-01

    Melanoma has continued to rise in incidence despite public efforts to promote sun protection behaviors. Because sunscreen use does not completely prevent skin cancer induced by ultraviolet radiation, additional chemopreventive methods for protecting against and reversing the effects of ultraviolet photodamage need evaluation. Recent years have brought increased interest in dietary factors, such as natural botanicals and vitamins, for the prevention of melanoma. This contribution provides a narrative review of the relevant, nutrition-related literature found by searching the keywords "melanoma chemoprevention," "nutrition and melanoma," "dietary botanicals and melanoma prevention," "green tea and melanoma," "vitamin D and melanoma," and "vitamin E and melanoma" in the PubMed database. Although randomized controlled trials of humans are lacking, basic science and epidemiologic studies show promising benefits of many natural products in chemoprevention for melanoma. Future studies, hopefully, will yield concrete answers and clarify the role of commonly available dietary nutrients in melanoma chemoprevention.

    2011-01-01

    Childhood obesity is a serious public health problem, demanding urgent and clear defined actions in order to stop the rapid increase on its prevalence and all health consequences associated. The best strategy to stop the rapid increase in childhood obesity is to prevent it. In order to do so, multiple defined actions between government, industry, community organizations, schools, families and health-care professionals. The general and family physicians, pediatricians, nurses, dieticians and other clinicians should be engaged, as a key actor, in the prevention of childhood obesity. The health-care professionals have frequent opportunities to inform to children, youth and their parents about the importance of prevention of obesity and to promote and engage them in healthy life styles, particularly, a healthy diet and regular physical activity.

  20. Probiotics for allergy prevention.

    Science.gov (United States)

    West, C E

    2016-01-01

    Probiotics, given either as a supplement or in infant foods, have been evaluated in randomised controlled trials for allergy prevention. Here, the aim is to give an overview of the results from these primary prevention studies and to discuss current strategies. In most studies, single strains or a mixture of strains of lactic acid bacteria and bifidobacteria have been used--prenatally, postnatally or perinatally. Several meta-analyses have reported a moderate benefit of probiotics for eczema prevention, and the most consistent effect has been observed with a combined perinatal intervention in infants at high risk of allergic disease due to familial predisposition. In a recent meta-analysis, the use of multi-strain probiotics appeared to be most effective for eczema prevention. No preventive effect has been shown for other allergic manifestations. As long-term follow-up data on later onset allergic conditions (asthma and allergic rhinitis) are available only from a few of the initiated studies, reports from ongoing follow-up studies that are adequately powered to examine long-term outcomes are anticipated to provide more insight. Arguably, the differences in many aspects of study design and the use of different probiotic strains and combinations have made direct comparison difficult. To date, expert bodies do not generally recommend probiotics for allergy prevention, although the World Allergy Organization (WAO) in their recently developed guidelines suggests considering using probiotics in pregnant women, during breastfeeding and/or to the infant if at high risk of developing allergic disease (based on heredity). However, in concordance with other expert bodies, the WAO guideline panel stressed the low level of evidence and the need for adequately powered randomised controlled trials and a more standardised approach before clinical recommendations on specific strains, dosages and timing can be given.

    A common approach to malaria prevention is to follow the "A, B, C, D" rule: Awareness of risk, Bite avoidance, Compliance with chemoprophylaxis, and prompt Diagnosis in case of fever. The risk of acquiring malaria depends on the length and intensity of exposure; the risk of developing severe disease is primarily determined by the health status of the traveler. These parameters need to be assessed before recommending chemoprophylaxis and/or stand-by emergency treatment. This review discusses the different strategies and drug options available for the prevention of malaria during and post travel.

    2015-06-01

    Due to progressive advances in surgical techniques, immunosuppressive therapies, and supportive care, outcomes from both solid organ transplantation and hematopoietic stem cell transplantation continue to improve. Thrombosis remains a challenging management issue in this context, with implications for both graft survival and long-term quality of life. Unfortunately, there remains a general paucity of pediatric-specific data regarding thrombosis incidence, risk stratification, and the safety or efficacy of preventative strategies with which to guide treatment algorithms. This review summarizes the available evidence and rationale underlying the spectrum of current practices aimed at preventing thrombosis in the transplant recipient, with a particular focus on risk factors, pathophysiology, and described antithrombotic regimens.

    The prevention of tooth decay and the treatment of lesions and cavities are ongoing challenges in dentistry. In recent years, biomimetic approaches have been used to develop nanomaterials for inclusion in a variety of oral health-care products. Examples include liquids and pastes that contain nano-apatites for biofilm management at the tooth surface, and products that contain nanomaterials for the remineralization of early submicrometre-sized enamel lesions. However, the treatment of larger visible cavities with nanomaterials is still at the research stage. Here, we review progress in the development of nanomaterials for different applications in preventive dentistry and research, including clinical trials.

However, the degree to which certain programs and controls are applied in smaller, less-complex entities and the formality of theirapplication are likely to differ from larger organizations.

  9. The sodium-glucose co-transporter 2 inhibitor empagliflozin improves diabetes-induced vascular dysfunction in the streptozotocin diabetes rat model by interfering with oxidative stress and glucotoxicity.

    Directory of Open Access Journals (Sweden)

    Matthias Oelze

    Full Text Available OBJECTIVE: In diabetes, vascular dysfunction is characterized by impaired endothelial function due to increased oxidative stress. Empagliflozin, as a selective sodium-glucose co-transporter 2 inhibitor (SGLT2i, offers a novel approach for the treatment of type 2 diabetes by enhancing urinary glucose excretion. The aim of the present study was to test whether treatment with empagliflozin improves endothelial dysfunction in type I diabetic rats via reduction of glucotoxicity and associated vascular oxidative stress. METHODS: Type I diabetes in Wistar rats was induced by an intravenous injection of streptozotocin (60 mg/kg. One week after injection empagliflozin (10 and 30 mg/kg/d was administered via drinking water for 7 weeks. Vascular function was assessed by isometric tension recording, oxidative stress parameters by chemiluminescence and fluorescence techniques, protein expression by Western blot, mRNA expression by RT-PCR, and islet function by insulin ELISA in serum and immunohistochemical staining of pancreatic tissue. Advanced glycation end products (AGE signaling was assessed by dot blot analysis and mRNA expression of the AGE-receptor (RAGE. RESULTS: Treatment with empagliflozin reduced blood glucose levels, normalized endothelial function (aortic rings and reduced oxidative stress in aortic vessels (dihydroethidium staining and in blood (phorbol ester/zymosan A-stimulated chemiluminescence of diabetic rats. Additionally, the pro-inflammatory phenotype and glucotoxicity (AGE/RAGE signaling in diabetic animals was reversed by SGLT2i therapy. CONCLUSIONS: Empagliflozin improves hyperglycemia and prevents the development of endothelial dysfunction, reduces oxidative stress and improves the metabolic situation in type 1 diabetic rats. These preclinical observations illustrate the therapeutic potential of this new class of antidiabetic drugs.

    Full Text Available Operation or any invasive procedure is a stressful event involving risks and complications. We should be able to offer a guarantee that the right procedure will be done on right person in the right place on their body. “Never events” are definable. These are the avoidable and preventable events. The people affected from consequences of surgical mistakes ranged from temporary injury in 60%, permanent injury in 33% and death in 7%”.World Health Organization (WHO [1] has earlier said that over seven million people across the globe suffer from preventable surgical injuries every year, a million of them even dying during or immediately after the surgery? The UN body quantified the number of surgeries taking place every year globally 234 million. It said surgeries had become common, with one in every 25 people undergoing it at any given time. 50% never events are preventable. Evidence suggests up to one in ten hospital admissions results in an adverse incident. This incident rate is not acceptable in other industries. In order to move towards a more acceptable level of safety, we need to understand how and why things go wrong and have to build a reliable system of working. With this system even though complete prevention may not be possible but we can reduce the error percentage2. To change present concept towards patient, first we have to change and replace the word patient with medical customer. Then our outlook also changes, we will be more careful towards our customers.

    Prevention, safety and health promotion represent fondamental issues in the Regional policy. With this regard, the implementation of the Regional policy has been thought as the promotion of an integrated system which links different fields such as health, work-related information and education, job orientation and work in general. It is recommended that a good standard of prevention is achieved through the synergic actions and the collaborations among all the different actors playing a role in safety and prevention in workplace, including occupational physicians, safety and prevention operators, safety representatives for workers, trade unions, employers associations and public institutions. It is also necessary to adopt a strategy in order to decrease the number of misdiagnosed occupational diseases as well as to promote the "culture of safety in workplaces", increasing the awareness of all figures, with special focus on employers category. All this has to be set in the new scenario of the nowadays work characterized by the progressive increase of atypical job contracts, renewing the emphasis on the necessity of keeping joined "the right to a job with the right to health".

    Raspe, Heiner

    2006-05-01

    Full Text Available Background: The condition of non-specific back pain is characterized by high prevalence, non satisfactory therapeutic options and severe socioeconomic consequences. Therefore prevention seems an attractive option to downsize the problem. However, the construction of effective preventive measures is complicated by the obscure aetiology of the condition, the multidimensionality of risk and prognostic factors (bio psychosocial model! and the variability of its natural as well as clinical course. This led to the development of a wide variety of preventive measures: e. g. exercise programs, educational measures (including back school, ergonomic modification of the work environment, mechanical supports (e. g. back belts as well as multidisciplinary interventions. For two reasons the workplace seems to be a suitable setting for prevention. First, because a number of strong risk factors are associated with working conditions and second, because it allows addressing a large proportion of the adult population. Against this background the assessment at hand sets out to answer the following questions: What is the amount and methodological quality of the available scientific literature on the effectiveness of back pain prevention in the workplace environment? What are effective measures for the prevention of back pain and its consequences in the workplace environment and how effective are they? Is back pain prevention in the workplace environment cost-effective? Is there a need for more research? As primary outcomes for effectiveness the assessment will focus on time lost from work and the frequency and duration of episodes with back pain. The preventive measures assessed belong to the following categories: exercise programs, educational and information measures, multidimensional interventions, back belts, lifting teams and ergonomic interventions. Methods: The assessment is based on a systematic review of the published literature according to the

  10. Prevention of nuclear war

    International Nuclear Information System (INIS)

    Removing the threat of a nuclear war-as the General Assembly formally stated in the Final Document of its first special session devoted to disarmament, in 1978-is considered to be the task of the present day. In that Document, the General Assembly sought to establish principles, guidelines and procedures for preventing nuclear war. It declared that to that end, it was imperative to remove the threat of nuclear weapons, to halt and reverse the nuclear-arms race until the total elimination of nuclear weapons and their delivery systems had been achieved (see chapter iv), and to prevent the proliferation of nuclear weapons (see chapter VII). At the same time, it called for other measures designed to prevent the outbreak of nuclear war and to lessen the danger of the treat or use of nuclear weapons. The Assembly's clear call for action was dictated by the awareness that there was no insuperable barrier dividing peace from war and that, unless nations brought the spiralling nuclear-arms race to an end, the day might come when nuclear weapons would actually be used, with catastrophic consequences. In adopting the Final Document, the international community achieved, for the first time, a consensus on an international disarmament strategy having as its immediate goal the elimination of the danger of a nuclear war and the implementation of measures to halt and reverse the arms race. The General Assembly, at its second special session on disarmament, in 1982, reaffirmed the validity of the 1978 Final Document. This paper reports that nuclear issues and in particular the prevention of nuclear war remain, however, major concerns of all States. Undoubtedly, all nations have a vital interest in the negotiation of effective measures for her prevention of nuclear war, since nuclear weapons pose a unique threat to human survival. If nuclear war were to occur, its consequences would be global, not simple regional

  11. GPER inhibits diabetes-mediated RhoA activation to prevent vascular endothelial dysfunction.

    The effect of estrogen receptors on diabetes-induced vascular dysfunction is critical, but ambiguous. Individuals with diabetic vascular disease may require estrogen receptor-specific targeted therapy in the future. The G protein-coupled estrogen receptor (GPER) has beneficial effects on vascular function. However, its fundamental mechanisms are unclear. The RhoA/Rho-kinase pathway contributes to diabetic vascular complications, whereas estrogen can suppress Rho-kinase function. Thus, we assumed that GPER inhibits diabetes-mediated RhoA activation to prevent vascular dysfunction. We further investigated the underlying mechanisms involved in this process. Vascular endothelial cells and ex vivo cultured ovariectomized (OVX) C57BL/6 mouse aortae were treated with high glucose (HG) alone or in combination with GPER agonist (G1). G1 treatment was also administered to OVX db/db mice for 8 weeks. An ex-vivo isovolumic myograph was used to analyze the endothelium-dependent vasodilation and endothelium-independent contraction of mouse aortae. Apoptosis, oxidative stress, and inflammation were attenuated in G1-pretreated vascular endothelial cells. G1 significantly decreased the phosphorylation of inhibitory endothelial nitric oxide (NO) synthase residue threonine 495 (eNOS Thr495), inhibited RhoA expression, and increased NO production. Additionally, G1 rescued the impaired endothelium-dependent relaxation and inhibited RhoA activation in the thoracic aorta of OVX db/db mice and ex-vivo cultured OVX C57BL/6 mouse aortae treated with HG. Estrogens acting via GPER could protect vascular endothelium, and GPER activation might elicit ERα-independent effect to inhibit RhoA/Rho-kinase pathway. Additionally, GPER activation might reduce vascular smooth muscle contraction by inhibiting RhoA activation. Thus, the results of the present study suggest a new therapeutic paradigm for end-stage vascular dysfunction by inhibiting RhoA/Rho-kinase pathway via GPER activation. PMID:26785611

    Energy Technology Data Exchange (ETDEWEB)

    Friedman, R.B. (Medical College of Virginia Hospitals, Richmond (USA))

    1990-01-01

    Osteoradionecrosis (ORN) is one of the most serious complications arising from head and neck radiation therapy. Current research has shown that ORN represents nonhealing, dead bone and is not a state of infection. ORN is the result of functional and structural bony changes that may not be expressed for months or years. ORN may occur spontaneously or in response to wounding. Predisposing factors include absorbed radiation dose, fractionation, delivery modality, and dental status. Timing of dental extractions and other factors have also been shown to affect incidence. ORN may be reduced through early intraoral evaluation, treatment, and adequate healing time prior to beginning RT. Hyperbaric oxygen (HBO) therapy has been beneficial in the prevention and treatment of ORN. It is of paramount importance for the medical community to recognize the factors that may reduce ORN incidence, endorse oral care protocols, and acknowledge the value of HBO therapy in the prevention and treatment of this disease. 60 references.

    Evidence linking alcohol and other drug abuse with child maltreatment, particularly neglect, is strong. But does substance abuse cause maltreatment? According to Mark Testa and Brenda Smith, such co-occurring risk factors as parental depression, social isolation, homelessness, or domestic violence may be more directly responsible than substance abuse itself for maltreatment. Interventions to prevent substance abuse-related maltreatment, say the authors, must attend to the underlying direct causes of both. Research on whether prevention programs reduce drug abuse or help parents control substance use and improve their parenting has had mixed results, at best. The evidence raises questions generally about the effectiveness of substance abuse services in preventing child maltreatment. Such services, for example, raise only marginally the rates at which parents are reunified with children who have been placed in foster care. The primary reason for the mixed findings, say Testa and Smith, is that almost all the parents face not only substance abuse problems but the co-occurring issues as well. To prevent recurring maltreatment and promote reunification, programs must ensure client progress in all problem areas. At some point in the intervention process, say Testa and Smith, attention must turn to the child's permanency needs and well-being. The best evidence to date suggests that substance-abusing parents pose no greater risk to their children than do parents of other children taken into child protective custody. It may be sensible, say the authors, to set a six-month timetable for parents to engage in treatment and allow twelve to eighteen months for them to show sufficient progress in all identified problem areas. After that, permanency plans should be expedited to place the child with a relative caregiver or in an adoptive home. Investing in parental recovery from substance abuse and dependence, the authors conclude, should not substitute for a comprehensive approach

    The incidence of cervical cancer has hopefully been dropping down in our industrialized countries since the introduction of both primary and secondary prevention. Nevertheless, it is still lethal in one out of two affected women though the introduction of cytological screening has dramatically reduced the mortality. Progressive diffusion of anti-HPV vaccination, the broadening of the viral types concerned, its association with existing screening measures and finally the introduction of viral detection as a screening tool must optimize the results already obtained.

  1. Preventing Ophthalmia Neonatorum

    Directory of Open Access Journals (Sweden)

    Dorothy L Moore

    2015-01-01

    Full Text Available The use of silver nitrate as prophylaxis for neonatal ophthalmia was instituted in the late 1800s to prevent the devastating effects of neonatal ocular infection with Neisseria gonorrhoeae. At that time – during the preantibiotic era – many countries made such prophylaxis mandatory by law. Today, neonatal gonococcal ophthalmia is rare in Canada, but ocular prophylaxis for this condition remains mandatory in some provinces/ territories. Silver nitrate drops are no longer available and erythromycin, the only ophthalmic antibiotic eye ointment currently available for use in newborns, is of questionable efficacy. Ocular prophylaxis is not effective in preventing chlamydial conjunctivitis. Applying medication to the eyes of newborns may result in mild eye irritation and has been perceived by some parents as interfering with mother-infant bonding. Physicians caring for newborns should advocate for rescinding mandatory ocular prophylaxis laws. More effective means of preventing ophthalmia neonatorum include screening all pregnant women for gonorrhea and chlamydia infection, and treatment and follow-up of those found to be infected. Mothers who were not screened should be tested at delivery. Infants of mothers with untreated gonococcal infection at delivery should receive ceftriaxone. Infants exposed to chlamydia at delivery should be followed closely for signs of infection.

  2. Guidelines for prevention in psychology.

    Science.gov (United States)

    2014-04-01

    The effectiveness of prevention to enhance human functioning and reduce psychological distress has been demonstrated. From infancy through adulthood, access to preventive services and interventions is important to improve the quality of life and human functioning and reduce illness and premature death. The importance of prevention is consistent with the Patient Protection and Affordable Care Act of 2010. Even with the increased focus on prevention, psychology training programs rarely require specific courses on prevention. In particular, conceptualizations about best practices in prevention, particularly at the environmental level, are lacking. Therefore, psychologists engaged in prevention can benefit from a set of guidelines that address and inform prevention practices. Accordingly, the Guidelines for Prevention in Psychology are intended to "inform psychologists, the public, and other interested parties regarding desirable professional practices" in prevention. The Prevention Guidelines are recommended based on their potential benefits to the public and the professional practice of psychology. They support prevention as an important area of practice, research, and training for psychologists. The Guidelines give increased attention to prevention within APA, encouraging psychologists to become involved with preventive activities relevant to their area of practice.

    Chi Zhang

    Full Text Available BACKGROUND: Emerging evidence showed the beneficial effect of acidic fibroblast growth factor (aFGF on heart diseases. The present study investigated whether non-mitogenic aFGF (nm-aFGF can prevent diabetic cardiomyopathy and the underlying mechanisms, if any. METHODOLOGY/PRINCIPAL FINDINGS: Type 1 diabetes was induced in mice by multiple intraperitoneal injections of low-dose streptozotocin. Hyperglycemic and age-matched control mice were treated with or without nm-aFGF at 10 µg/kg daily for 1 and 6 months. Blood pressure and cardiac function were assessed. Cardiac H9c2 cell, human microvascular endothelial cells, and rat cardiomyocytes were exposed to high glucose (25 mM for mimicking an in vitro diabetic condition for mechanistic studies. Oxidative stress, DNA damage, cardiac hypertrophy and fibrosis were assessed by real-time qPCR, immunofluorescent staining, Western blotting, and pathological examination. Nm-aFGF significantly prevented diabetes-induced hypertension and cardiac dysfunction at 6 months. Mechanistic studies demonstrated that nm-aFGF showed the similar preventive effect as the native aFGF on high glucose-induced oxidative stress (increase generation of reactive oxygen species and damage (cellular DNA oxidation, cell hypertrophy, and fibrotic response (increased mRNA expression of fibronectin in three kinds of cells. These in vitro findings were recaptured by examining the heart of the diabetic mice with and without nm-aFGF. CONCLUSIONS: These results suggest that nm-aFGF can prevent diabetic cardiomyopathy, probably through attenuation of cardiac oxidative stress, hypertrophy, and fibrosis.

  4. Serelaxin (recombinant human relaxin-2) prevents high glucose-induced endothelial dysfunction by ameliorating prostacyclin production in the mouse aorta.

    Diabetes-induced endothelial dysfunction is a critical initiating factor in the development of cardiovascular complications. Treatment with relaxin improves tumour necrosis factor α-induced endothelial dysfunction by enhancing endothelial nitric oxide synthase (eNOS) activity and restoring superoxide dismutase 1 protein in rat aortic rings ex vivo. It is, therefore, possible that relaxin treatment could alleviate endothelial dysfunction in diabetes. This study aimed to test the hypothesis that serelaxin (recombinant human relaxin-2) prevents high glucose-induced vascular dysfunction in the mouse aorta. Abdominal aortae were isolated from C57BL/6 male mice and incubated in M199 media for 3days with either normal glucose (5.5mM) or high glucose (30mM), and co-incubated with placebo (20mM sodium acetate) or 10nM serelaxin at 37°C in 5% CO2. Vascular function was analysed using wire-myography. High glucose significantly reduced the sensitivity to the endothelium-dependent agonist, acetylcholine (ACh) (pEC50; normal glucose=7.66±0.10 vs high glucose=7.29±0.10, n=11-12, Paortae, but had no effect in serelaxin treated aortae. This suggests that high glucose incubation alters the superoxide and COX-sensitive pathway, which was normalized by co-incubation with serelaxin. Neither high glucose incubation nor serelaxin treatment had an effect on cyclooxygenase 1 and 2 (Ptgs1, Ptgs2), prostacyclin synthase (PTGIS) and receptor (Ptgir) as well as thromboxane A2 receptor (Tbxa2r) mRNA expression. Importantly, production of prostacyclin was significantly (Paortae, which was prevented by serelaxin treatment. Our data show that serelaxin treatment for 3 days restores high glucose-induced endothelial dysfunction by ameliorating vasodilator prostacyclin production and possibly through the reduction of superoxide in the mouse aorta.

    Claudio Maffeis

    2014-06-01

    Full Text Available Childhood obesity is the metabolic disorder with the highest prevalence in both children and adults. Urgency to treat and prevent childhood obesity is based on the clear evidence that obesity tends to track from childhood to adulthood, is associated to morbidity also in childhood and to long-term mortality. Early life, i.e., intrauterine life and the first two years, is a sensitive window for prevention. Anatomical and functional maturation of the hypothalamic structures devoted to regulating energy intake and expenditure and body size mainly occurs in the first 1,000 days of life. Therefore, factors affecting the foetal exposition to maternal metabolic environment and early postnatal nutrition are crucial in modulating the definition of the metabolic programming processes in the brain. Maternal diseases, mainly malnutrition for defect or excess, obesity and diabetes, placental disorders and dysfunctions, maternal use of alcohol and drugs, smoking, affect long term metabolic programming of the foetus with lifelong consequences. Similarly, early nutrition contributes to complete the long-term metabolic regulating framework initiated in the uterus. Breastfeeding, adequate weaning, attention to portion size and diet composition are potential tools for reducing the obesity risk later in childhood. Longitudinal randomized controlled studies are needed for exploring the efficacy of obesity prevention strategies initiated after conception.Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014 · The last ten years, the next ten years in Neonatology Guest Editors: Vassilios Fanos, Michele Mussap, Gavino Faa, Apostolos Papageorgiou

  20. Prevention of foodborne listeriosis

    Directory of Open Access Journals (Sweden)

    Rebagliati Victoria

    2009-04-01

    Full Text Available Listeria monocytogenes is a foodborne pathogen that can cause serious invasive illness, mainly in certain well-defined high-risk groups, including elderly and immunocompromised patients, pregnant women, newborns and infants. L. monocytogenes primarily causes abortion, septicemia or meningitis. Contaminated meats (such as hot dogs, delicatessen meats and patι, dairy products and seafood have all been implicated in outbreaks of listeriosis. The public health importance of listeriosis is not always recognized, particularly because listeriosis is a relatively rare disease compared with other common foodborne illnesses such as salmonellosis or botulism. However, because of its high case fatality rate, listeriosis ranks among the most frequent causes of death due to foodborne illness, ranking second after salmonellosis. L. monocytogenes emerged as an important foodborne pathogen in the latter part of the 20th century. Extensive work has been performed in many countries during the last decade to prevent outbreaks and decrease the incidence of listeriosis. An important reduction occurred in listeriosis incidence in some of these countries during the 90s, suggesting a relationship between preventive measures and incidence decrease of human listeriosis.

  1. Initiatives for proliferation prevention

    International Nuclear Information System (INIS)

    Preventing the proliferation of weapons of mass destruction is a central part of US national security policy. A principal instrument of the Department of Energy's (DOE's) program for securing weapons of mass destruction technology and expertise and removing incentives for scientists, engineers and technicians in the newly independent states (NIS) of the former Soviet Union to go to rogue countries or assist terrorist groups is the Initiatives for Proliferation Prevention (IPP). IPP was initiated pursuant to the 1994 Foreign Operations Appropriations Act. IPP is a nonproliferation program with a commercialization strategy. IPP seeks to enhance US national security and to achieve nonproliferation objectives by engaging scientists, engineers and technicians from former NIS weapons institutes; redirecting their activities in cooperatively-developed, commercially viable non-weapons related projects. These projects lead to commercial and economic benefits for both the NIS and the US IPP projects are funded in Russian, Ukraine, Kazakhstan and Belarus. This booklet offers an overview of the IPP program as well as a sampling of some of the projects which are currently underway

    Chiolero, Arnaud; Paccaud, Fred; Aujesky, Drahomir; Santschi, Valérie; Rodondi, Nicolas

    2015-01-01

    Overdiagnosis is the diagnosis of an abnormality that is not associated with a substantial health hazard and that patients have no benefit to be aware of. It is neither a misdiagnosis (diagnostic error), nor a false positive result (positive test in the absence of a real abnormality). It mainly results from screening, use of increasingly sensitive diagnostic tests, incidental findings on routine examinations, and widening diagnostic criteria to define a condition requiring an intervention. The blurring boundaries between risk and disease, physicians' fear of missing a diagnosis and patients' need for reassurance are further causes of overdiagnosis. Overdiagnosis often implies procedures to confirm or exclude the presence of the condition and is by definition associated with useless treatments and interventions, generating harm and costs without any benefit. Overdiagnosis also diverts healthcare professionals from caring about other health issues. Preventing overdiagnosis requires increasing awareness of healthcare professionals and patients about its occurrence, the avoidance of unnecessary and untargeted diagnostic tests, and the avoidance of screening without demonstrated benefits. Furthermore, accounting systematically for the harms and benefits of screening and diagnostic tests and determining risk factor thresholds based on the expected absolute risk reduction would also help prevent overdiagnosis.

    Preventing the proliferation of weapons of mass destruction is a central part of US national security policy. A principal instrument of the Department of Energy`s (DOE`s) program for securing weapons of mass destruction technology and expertise and removing incentives for scientists, engineers and technicians in the newly independent states (NIS) of the former Soviet Union to go to rogue countries or assist terrorist groups is the Initiatives for Proliferation Prevention (IPP). IPP was initiated pursuant to the 1994 Foreign Operations Appropriations Act. IPP is a nonproliferation program with a commercialization strategy. IPP seeks to enhance US national security and to achieve nonproliferation objectives by engaging scientists, engineers and technicians from former NIS weapons institutes; redirecting their activities in cooperatively-developed, commercially viable non-weapons related projects. These projects lead to commercial and economic benefits for both the NIS and the US IPP projects are funded in Russian, Ukraine, Kazakhstan and Belarus. This booklet offers an overview of the IPP program as well as a sampling of some of the projects which are currently underway.

  4. Resveratrol Prevention of Diabetic Nephropathy Is Associated with the Suppression of Renal Inflammation and Mesangial Cell Proliferation: Possible Roles of Akt/NF-κB Pathway

    Full Text Available The present study was to investigate the protection of resveratrol (RSV in diabetes associated with kidney inflammation and cell proliferation. Rat mesangial cell and streptozotocin-induced type 1 diabetes mouse model were used. In vitro, RSV attenuated high glucose-induced plasminogen activator inhibitor (PAI-1 expression and mesangial cell proliferation, as well as Akt and nuclear factor-kappa B (NF-κB activation. The similar results were recaptured in the experiment with Akt inhibitors. In vivo, mice were divided into three groups: control group, diabetes mellitus (DM group, and RSV-treated DM group. Compared with control group, the kidney weight to body weight ratio and albumin to creatinine ratio were increased in DM group, but not in RSV-treated DM group. Furthermore, the increased expression of PAI-1 and intercellular adhesion molecule-1 in diabetic renal cortex were also reduced by RSV administration. Besides, the kidney p-Akt/Akt ratio and NF-κB were significantly increased in DM group; however, these changes were reversed in RSV-treated DM group. Additionally, immunohistochemistry results indicated that RSV treatment reduced the density of proliferating cell nuclear antigen-positive cells significantly in glomeruli of diabetic mice. These results suggest that RSV prevents diabetes-induced renal inflammation and mesangial cell proliferation possibly through Akt/NF-κB pathway inhibition.

  9. N-3 polyunsaturated Fatty acids prevent diabetic retinopathy by inhibition of retinal vascular damage and enhanced endothelial progenitor cell reparative function.

    Directory of Open Access Journals (Sweden)

    Maria Tikhonenko

    Full Text Available OBJECTIVE: The vasodegenerative phase of diabetic retinopathy is characterized by not only retinal vascular degeneration but also inadequate vascular repair due to compromised bone marrow derived endothelial progenitor cells (EPCs. We propose that n-3 polyunsaturated fatty acid (PUFA deficiency in diabetes results in activation of the central enzyme of sphingolipid metabolism, acid sphingomyelinase (ASM and that ASM represents a molecular metabolic link connecting the initial damage in the retina and the dysfunction of EPCs. RESEARCH DESIGN AND METHODS: Type 2 diabetic rats on control or docosahexaenoic acid (DHA-rich diet were studied. The number of acellular capillaries in the retinas was assessed by trypsin digest. mRNA levels of interleukin (IL-1β, IL-6, intracellular adhesion molecule (ICAM-1 in the retinas from diabetic animals were compared to controls and ASM protein was assessed by western analysis. EPCs were isolated from blood and bone marrow and their numbers and ability to form colonies in vitro, ASM activity and lipid profiles were determined. RESULTS: DHA-rich diet prevented diabetes-induced increase in the number of retinal acellular capillaries and significantly enhanced the life span of type 2 diabetic animals. DHA-rich diet blocked upregulation of ASM and other inflammatory markers in diabetic retina and prevented the increase in ASM activity in EPCs, normalized the numbers of circulating EPCs and improved EPC colony formation. CONCLUSIONS: In a type 2 diabetes animal model, DHA-rich diet fully prevented retinal vascular pathology through inhibition of ASM in both retina and EPCs, leading to a concomitant suppression of retinal inflammation and correction of EPC number and function.

    Full Text Available This study is aimed to examine preschool teachers’ knowledge of, attitudes about, and training related to child sexual abuse (CSA prevention in Beijing, China. Two hundred and forty-five preschool teachers were administered the 16-item questionnaire that contained questions on CSA prevention knowledge, attitudes, and teacher training. Results showed that Chinese preschool teachers had limited knowledge on CSA prevention (M = 4.86, SD = 2.12. Less than 5% of the teachers ever attended CSA prevention training programs. Preschool teachers’ training on CSA prevention was the significant factor for their knowledge and attitudes. To help protect children against sexual abuse, there is an urgent need to develop appropriate prevention training programs for preschool teachers in China.

  18. Prevention of nuclear war

    International Nuclear Information System (INIS)

    Physicians are exercising their responsibility as healers in their efforts to prevent nuclear war. Death for Hiroshima survivors was experienced in four stages: the immediate impact of destruction, the acute impact of radiation, delayed radiation effects, and later identification as an atomic bomb survivor. Each phase had its physical and psychological impacts and negates Hiroshima as a model for rational behavior despite those who claim survival is possible for those who are prepared. The psychic effects of modern nuclear, chemical, and germ warfare need to be challenged with a symbolization of life and immortality. Studies of psychological reactions to the terror children felt during practice air-raid drills indicate that the fears can be surpressed and re-emerge in adult life as a linking of death with collective annihilation. Other themes which emerge are feelings of impermanence, craziness, identification with the bomb, and a double existence. Psychic numbing and the religion of nuclearism cause dangerous conflicts with the anxieties caused by increasing awareness of death

    Full Text Available ABSTRACT: Rabies is a zoonotic disease and its magnitude of problem is underestimated due to lack of surveillance. In spite of hundred percent fa tality, the optimistic view is that it is totally and absolutely preventable with the aid of effective post-exposure prophylaxis. It is prevalent mainly in the developing countries like Africa and A sia. Wild carnivorous animals act as reservoir and domestic/peridomestic warm blooded ani mals transmit the virus to the human population. It is popularly known as “Hydrophobia” in h uman and children are at particularly risk. More than 3.3 billion people live in regions w here rabies is enzootic. Dog bite is the principal mode of infection in India and lower limb i s the most common site of injury. Ineffective surveillance, shortage of TCV and Immunoglobulin ma nufacturer and its high cost, peoples ignorance of first aid measures after bite and the importance of compliance of PEP, uncontrolled street dog population etc. are the key issues which should be addressed to tackle this problem.

    1991-01-01

    Citric acid tablets, which slowly release citric acid when flushed with water, are under development by the Navy for calcification prevention. The citric acid dissolves calcium carbonate deposits and chelates the calcium. For use in urinals, a dispenser is not required because the tablets are non-toxic and safe to handle. The tablets are placed in the bottom of the urinal, and are consumed in several hundred flushes (the release rate can be tailored by adjusting the formulation). All of the ingredients are environmentally biodegradable. Mass production of the tablets on commercial tableting machines was demonstrated. The tablets are inexpensive (about 75 cents apiece). Incidences of clogged pipes and urinals were greatly decreased in long term shipboard tests. The corrosion rate of sewage collection pipe (90/10 Cu/Ni) in citric acid solution in the laboratory is several mils per year at conditions typically found in traps under the urinals. The only shipboard corrosion seen to date is of the yellow brass urinal tail pieces. While this is acceptable, the search for a nontoxic corrosion inhibitor is underway. The shelf life of the tablets is at least one year if stored at 50 percent relative humidity, and longer if stored in sealed plastic buckets.

  2. Pollution prevention: A regulatory update

    International Nuclear Information System (INIS)

    Pollution prevention is the emphasis of the 1990s environmental philosophy. This new environmental era was ushered in when President Bush signed the Pollution Prevention Act in October 1990. This law, with its accompanying philosophy, was in response to the realization that end-of-the-pipe treatment, which frequently changed the media in which a pollutant or waste was discharged, was inadequate to protect the environment and human health. Pollution prevention advocates source reduction, where material substitutions and engineering solutions are sought to reduce the volume and toxicity of waste and pollutants. This proactive approach reduces environmental impacts such as those of former waste sites which have produced environmental legacies that will cost billions of dollars and take decades to remediate. This paper describes pollution prevention philosophy and summarizes regulatory pollution prevention requirements. It describes current regulatory trends in the area of pollution prevention, including voluntary programs and enforcement actions. The Pollution Prevention Act of 1990 is described, and pollution prevention initiatives embodied in other laws, including the Clean Air Act, the Clean Water Act, the Emergency Planning and Community Right-To-Know Act, the Resource Conservation and Recovery Act, and the Toxic Substances Control Act, are discussed. A historical overview of waste minimization initiatives within the Department of Energy is given, and other pollution prevention initiatives that affect federal facilities, such as Executive Order 12780, which mandates recycling and the procurement of recycled materials, are also outlined

    Full Text Available Aim: To determine the anti-carious effect of coffee in humans. Coffee represents one of the most consumed products by the population. Materials and Methods: A random sample of 1000 individuals, of both sexes, who consumed only coffee as a beverage and who visited the Out-Patient Department of KLE Society′s Institute of Dental Sci-ences, with a dental complaint and no history of any major illness, were considered as subjects. The patients′ histories with regard to the coffee intake, such as, period of consumption, frequency of consumption, whether taken with milk or wihout milk, with sugar or without sugar, and the brand make, was noted. History of the type of diet, consumption of sweets, periodic-ity of brushing, and whether they had undergone fluoride applications were also noted. A thousand patients who consumed beverages other than coffee were taken as the control. Results: The results showed that coffee most consumed was roasted coffee, and the frequency on an average was about three cups per day, for an average period of 35 years. The Decayed/Missing/Filled Surface (DMFS scores varied from 2.9, in subjects who drank black coffee, to 5.5 in subjects who consumed coffee together with sweeteners and creaming agents. The DMFS score was 3.4 in subjects who consumed coffee together with milk but no sugar. The DMFS score of the control subjects was 4, indicating that coffee if consumed alone had anticaries action, but in the presence of additives the antibacterial and anticaries action was totally minimized. Conclusion: Thus coffee can help in prevention of dental caries if consumed without additives.

  5. Prevention of Iatrogenic Keratectasia.

    Rapuano, C J

    2016-06-01

    Iatrogenic corneal ectasia is a rare but devastating complication after refractive surgery. While its incidence appears to be declining, it has not been eliminated. Its cause is probably related to a combination of an intrinsic predisposition to ectasia and an additional anatomical destabilising effect from the refractive surgery. Determining which eyes are intrinsically "weak" and exactly how much additional "weakening" an eye can withstand before developing progressive thinning and protrusion are both difficult tasks. The essentially universal availability of corneal topography and the increasing use of corneal tomography have significantly improved our ability to preoperatively diagnose early forms of corneal ectasias, especially keratoconus and pellucid marginal degeneration. Advanced software algorithms have also enhanced the sensitivity and specificity of these technologies. Newer technologies, such as measuring corneal biomechanics and corneal epithelial distribution, will hopefully continue to help us to differentiate normal from abnormal corneas preoperatively. In addition to abnormalities in anterior and posterior corneal curvature, a number of other risk factors for the development of post-refractive surgery ectasia have been proposed, including younger patient age, thinner central corneal thickness, thinner residual stromal bed thickness and high myopia. If the percentage of altered tissue is > 40 %, this is an extremely accurate predictor of corneal ectasia after refractive surgery. While there are a number of effective treatments for iatrogenic corneal ectasia, such as contact lenses, corneal crosslinking, intracorneal rings and corneal transplantation, prevention should be the goal. With newer and better corneal imaging technology to help screen out patients with abnormal corneas along with an improved understanding of exactly how much weakening a given cornea can take, we should be able to minimize this vision threatening complication.

    One third of all occupation-related diseases are diseases of the skin, and in most of these cases the skin barrier is involved. Professions such as metalworkers, hairdressers, and health care and construction workers are mainly affected. Among them, contact dermatitis is the leading skin disease. It usually presents as hand eczema caused by or leading to impaired barrier function. All this significantly impacts the function of the hands, reduces the ability to work and especially impairs the patient's quality of life. Diagnostics and therapy are of great importance; in addition, prevention programs are meanwhile an important mainstay of the overall therapeutic concept. They comprise measures of secondary (outpatient) and tertiary (inpatient) prevention. Secondary prevention measures include occupation-tailored teaching and prevention programs, and the dermatologist's examination and report. In severe cases or if therapy is not successful in the long term, or if the diagnosis is not clear, measures of tertiary prevention may come into action. They are offered as an inpatient treatment and prevention program. The aims are prevention of the job loss, but especially to reach a long-term healing up and getting back to normal occupational and leisure life in the sense of attaining full quality of life. During the last years, research in Germany has shown that the different measures of prevention in occupational dermatology are very effective. This integrated concept of an in-/outpatient disease management reveals remarkable pertinent efficacy for patients with severe occupational dermatoses in at-risk professions. PMID:26844907

    Asthma and allergic diseases have become one of the epidemics of the 21st century in developed countries. Much of the success of other areas of medicine, such as infectious diseases, lies on preventive measures. Thus, much effort is also being placed lately in the prevention of asthma and allergy....... This manuscript reviews the current evidence, divided into four areas of activity. Interventions modifying environmental exposure to allergens have provided inconsistent results, with multifaceted interventions being more effective in the prevention of asthma. Regarding nutrition, the use of hydrolyzed formulas...... that antiviral vaccines could be useful in the future. Allergen-specific immunotherapy is effective for the treatment of allergic patients with symptoms; the study of its value for primary and secondary prevention of asthma and allergy is in its very preliminary phases.

  16. Preventive aspects regarding back pain.

    Science.gov (United States)

    Dorner, Thomas E; Crevenna, Richard

    2016-02-01

    Prevention, as the act of keeping from happening, aims to avert things that would occur if no intervention would be taken. From the epidemiology of back pain, consequences of the disease that are worth preventing can be derived. Biological, psychological, and social factors lead to back pain and chronification and ultimately to various adverse outcomes. The most important preventable consequences of back pain include loss of ability to function in daily life, loss of work productivity, sickness absence, and disability pension, excessive and inappropriate healthcare utilisation, impairments in quality of life, and disturbance of sexual life. The most important tools for prevention of back pain lie within rehabilitation after acute pain treatment and include exercise and physical training as well as health education and increasing health literacy. The bio-psycho-social nature of back pain must be taken into account in all preventive measures. PMID:26695480

  17. Primary prevention of Down's syndrome

    Directory of Open Access Journals (Sweden)

    2005-07-01

    Full Text Available Background: Antenatal screening has the capacity to detect more than 90% of Down's syndrome pregnancies leading to therapeutic abortion. Successes in recent years with such so-called 'secondary' prevention have not been matched with progress in primary prevention. Despite considerable research over many decades the principle cause of the disorder is unknown. Methods: This paper considers three potential primary prevention strategies, (1 avoiding reproduction at advanced maternal age, (2 pre-implantation genetic diagnosis for couples who are at high risk of Down's syndrome, and (3 folic acid supplementation. The principle aetiological hypotheses are also reviewed. Interpretation: A strategy of completing the family before a maternal age of 30 could more than halve the birth prevalence of this disorder. Women with a high a priori risk should have access to pre-implantation genetic diagnosis, which can lead to a reasonably high pregnancy rate with an extremely low risk of a Down's syndrome. The evidence suggesting an aetiological role for defective folate and methyl metabolism is not sufficient to justify an active preventative strategy of folic acid supplementation without performing a large clinical trial. Current supplementation policies designed to prevent neural tube defects may incidentally prevent Down's syndrome, provided a sufficiently high dose of folic acid is used. Further progress in primary prevention is hampered by limited aetiological knowledge and there is an urgent need to refocus research in that direction.

  15. Combination prevention: a deeper understanding of effective HIV prevention.

    Science.gov (United States)

    Hankins, Catherine A; de Zalduondo, Barbara O

    2010-10-01

    Evidence-informed and human rights-based combination prevention combines behavioural, biomedical, and structural interventions to address both the immediate risks and underlying causes of vulnerability to HIV infection, and the pathways that link them. Because these are context-specific, no single prescription or standard package will apply universally. Anchored in 'know your epidemic' estimates of where the next 1000 infections will occur and 'know your response' analyses of resource allocation and programming gaps, combination prevention strategies seek to realign programme priorities for maximum effect to reduce epidemic reproductive rates at local, regional, and national levels. Effective prevention means tailoring programmes to local epidemics and ensuring that components are delivered with the intensity, quality, and scale necessary to achieve intended effects. Structural interventions, addressing the social, economic, cultural, and legal constraints that create HIV risk environments and undermine the agency of individuals to protect themselves and others, are also public goods in their own right. Applying the principles of combination prevention systematically and consistently in HIV programme planning, with due attention to context, can increase HIV programme effectiveness. Better outcome and impact measurement using multiple methods and data triangulation can build the evidence base on synergies between the components of combination prevention at individual, group, and societal levels, facilitating iterative knowledge translation within and among programmes.

    Heine, Ralf G

    2014-01-01

    Due to the recent exponential increase in food allergies and atopic disorders, effective allergy prevention has become a public health priority in many developed regions. Important preventive strategies include the promotion of breastfeeding and vaginal deliveries, judicious use of perinatal antibiotics, as well as the avoidance of maternal tobacco smoking. Breastfeeding for at least 6 months and introduction of complementary solids from 4-6 months are generally recommended. Complex oligosaccharides in breast milk support the establishment of bifidobacteria in the neonatal gut which stimulate regulatory T lymphocyte responses and enhance tolerance development. Maternal elimination diets during pregnancy or lactation are not effective in preventing allergies. If exclusive breastfeeding is not possible, (supplemental) feeding with a partially hydrolyzed whey-based formula or extensively hydrolyzed casein-based formula may reduce the risk of cow's milk allergy and atopic dermatitis in infants with a family history of atopy. By contrast, asthma and allergic rhinitis at 4-6 years of age are not prevented by this approach. Soy formula and amino acid-based formula have no proven role in allergy prevention. Perinatal supplementation with probiotics and/or prebiotics may reduce the risk of atopic dermatitis, but no reliable effect on the prevention of food allergy or respiratory allergies has so far been found. A randomized trial on maternal fish oil supplementation during pregnancy found that atopic dermatitis and egg sensitization in the first year of life were significantly reduced, but no preventive effect for food allergies was demonstrated. The role of vitamin D deficiency or excess as a risk factor for food allergy and atopic disorders requires further study. PMID:24504215

  2. Prevention strategies for prostate cancer.

    2012-12-01

    Through the last decade consideration of the role of vitamins and minerals in primary prevention of genitourinary tumors has dramatically changed. Despite all efforts efficacy of a specific compound has not been proven, so far. In consequence, recommendations for a use of vitamins or other supplements with the intention of prostate cancer prevention should be avoided today. In contrast, there is some evidence that life style modification might be helpful: recent investigations suggest that smoking may be involved in prostate cancer carcinogenesis. In addition, there is evidence that moderate food consumption, reduction of dairy products and an Asian or Mediterranean diet might not only prevent prostate cancer but also harbors additional beneficial effects on general health. This move from single compounds to more complex diets can be considered as a change of paradigm in prostate cancer prevention and could be the starting point of future epidemiological research. Disappointing findings with regards to nutritional cancer prevention contrast with a solid evidence concerning the efficacy of chemoprevention using 5a-reductase inhibitors: Long-term use of Finasteride and Dutasteride significantly reduces prostate cancer detection. Further candidate drugs are under investigation. However, translation of these findings into urological practice remains a matter of controversial discussion. PMID:23288209

The basic concepts are defined, the principles and fundamentals of international regulations analysed, and the regulatory system in Croatia covered by statute and money laundering prevention Regulations is presented, in conjunction with a description of the organisation, remit and international actions of the Money Laundering Prevention Office.The infiltration of dirty money is a crucial problem from national economies. The purchase of shares, of real estate, the establishment of dirty investment funds and the use of the banking system for the embedding of such resources is a danger to the credibility of a whole country, and in particular to the security of the financial and banking system. Croatia has adopted statutory measures aimed at the effective detection and prevention of suspicious financial transactions, in other words the prevention of money laundering.Launderers constantly find new ways, make use of new non-financial channels and expand their activities to real estate, artworks and insurance. Hence it is necessary to keep up with European approaches and recommendations, to strive for further improvement of the laws and the modernisation of the system, and to adopt new regulations harmonised with international standards, particularly with Directive 2005/60/EC.

    Teenage pregnancy is associated with many health, emotional and socioeconomic problems including higher rates of anemia, labor complications, mortality, legal and social struggles and hhigher divorce rates. Professional social workers need strategies to help teenagers avoid early, unwanted pregnancy. This paper offers promising experential and research backing for a primary prevention group work strategy for all adolescents. Social and health programs overlook educational, cognitive anc interpersonal factors biasing youths' ability to comprehend and regulate contraception. Primary prevention to assist adolescents in thinking analytically about their sexual behavior must stress problem solving and decision-making as well as facts about human reproduction and birth control. To implement decisions, youths also need interpersonal communication skills. Small groups are ideal for delivering cognitive-behavioral primary prevention. This approach is based on the premise that youths become pregnant not because of a lack of relevant information, but because they lack cognitive and behavioral skills necessary to use information. Group work involving role-playing helps develop communication skills. Results from 2 field studies describe short-term and longitudinal benefits of the prevention strategy. Professionals can reach significant numbers of youth in this way. By treating sexual issues and the risk of pregnancy as normal in adolescence, social workers can introduce information and pertinent skills to all teenagers. No one is singled out as deviant and the group format enables young people to discuss taboo topics, discovering what the norms are and gradually learning how to deal with peers, family members, techers and others. Adolescents in primary prevention groups gained knowledge, cognitive skills and communication acumen. Improved attitudes toward family planning, increased regular contraception and less unsafe sex resulted from this cognitive-behavioral approach

    The refeeding syndrome can be defined as the metabolic alterations developed by the rapid nutrition repletion (oral, enteral as well as parenteral feeding) of severaly malnourished patients. Refeeding syndrome is a potentially fatal clinical condition and it is often underdiagnosed on non-specialized nutrition units. The most important key for its prevention is to identify patients at high risk for developing refeeding syndrome, before nutrition repletion. The present case describes the steps to prevent the refeeding syndrome as well as the clinical recommendations to restart nutrition support.

    Objective To study the erectile dysfunction in rats with diabetes induced by high-lipid feeding and low-dose streptozotocin (STZ) intra-abdominal injection. Methods Sixty 6-week old healthy male Wistar rats with normal e-rectile function were randomly divided into diabetic group (50 rats) and control group (10 rats, normal diet feeding). After eight weeks of high-lipid diet feeding, the diabetic model group accepted intra-abdominal injection of STZ, 35 mg/kg. At the ninth week, the tail vein blood was sampled to test the fasting glucose and lipid profile (low-intensity lipoprotein cholesterol and triglyceride) and the fasting plasma insulin. Apomorphine (APO) function test was performed to test the erectile function. Results After 8-week of high-lipid diet feeding, the weight of rats was significant increased. After injecting STZ, the blood gluscose of the diabetic group (increased to (14. 8 ± 3. 9) mmol/L), the serum insulin (decreased to (4. 3 ± 0. 7) uIU/L) and the insulin resistance index were all significantly different from those of the control group (P <0. 05). Serum triglyceride and low-intensity lipoprotein cholesterol were higher in diabetic group than those in control group (P<0. 05). There was no obivous change of the erectile function in normal group and the erection rate was 100%. In diabetic group, 1 rat died after STZ injection, 24 rats showed erection and the erectile rate (48. 9%) was significantly lower than that in normal group. Conclusion Diabetes rats induced by high-lipid feeding and low-dose STZ intra-abdominal injection have increased glucose, insulin resistance and erectile dysfunction, which can be utilized as the the model of type 2 diabetes complicated with erectile dysfunction.%目的 研究高脂喂养联合小剂量链脲佐菌素注射制备的糖尿病(diabetes mellitus,DM)大鼠的勃起功能.方法 60只6周龄,勃起功能正常的SD大鼠随机分为对照组(10只)和实验组(50只).实验组高脂喂养8周

Correspondingly, swimming exercise could decline the ratio of Bax/Bcl-2, considerably improve the survival pathway and further activate GSK-3β protein phosphorylation { P < 0. 05 ). In addition, swimming exercise also could augment insulin receptor IR1 (P < 0.05) contents. Although the level of IR2 was enhanced, there is no divergence for statistics. Conclusion; Swim training can effectively inhibit type 2 diabetes-induced myocardial apoptosis in Wistar rats. This anti-apoptotic effect may be through, at least in part, increasing the contents of IR1 receptor, and thereby activate PI3K-Akt signal cascade and further decline the phosphorylation expression of its key downstream of protein-GSK-3β, suggesting that swimming training may be an appropriate modality for combating with myocardial cell damage caused by T2DM.

    2012-04-01

    Full Text Available Background: An ageing population, a growing prevalence of chronic diseases and limited financial resources for health care underpin the importance of prevention of disabling health disorders and care dependency in the elderly. A wide variety of measures is generally available for the prevention of falls and fall-related injuries. The spectrum ranges from diagnostic procedures for identifying individuals at risk of falling to complex interventions for the removal or reduction of identified risk factors. However, the clinical and economic effectiveness of the majority of recommended strategies for fall prevention is unclear. Against this background, the literature analyses in this HTA report aim to support decision-making for effective and efficient fall prevention.Research questions: The pivotal research question addresses the effectiveness of single interventions and complex programmes for the prevention of falls and fall-related injuries. The target population are the elderly (> 60 years, living in their own housing or in long term care facilities. Further research questions refer to the cost-effectiveness of fall prevention measures, and their ethical, social and legal implications. Methods: Systematic literature searches were performed in 31 databases covering the publication period from January 2003 to January 2010. While the effectiveness of interventions is solely assessed on the basis of randomised controlled trials (RCT, the assessment of the effectiveness of diagnostic procedures also considers prospective accuracy studies. In order to clarify social, ethical and legal aspects all studies deemed relevant with regard to content were taken into consideration, irrespective of their study design. Study selection and critical appraisal were conducted by two independent assessors. Due to clinical heterogeneity of the studies no meta-analyses were performed.Results: Out of 12,000 references retrieved by literature searches, 184 meet the

    2015-01-01

    Full Text Available This paper reviews scientific research on occupational back pain and focuses on prevention of this problem. It discusses some of the challenges of translating the evidence of this multi-factorial condition into policy. Medical science is currently unable to clearly distinguish between back pain caused by work and that possibly due to other causes but which affects the individual′s capacity to work. Back pain affects the vast majority of people at some point in their lives and is very costly to both the health care system and the industry. Evidence suggests that heavy lifting, driving, and vibration of the whole body are linked to occupational back pain. Once the risk factors for occupational back pain are identified, an otherwise chronic and disabling condition can be prevented in the majority of patients. As explained in this article, three levels of prevention for occupational back pain have been reported as effective. Failure to implement preventive measures may lead to a high incidence of occupational back pain.

    2015-11-23

    Pancreatic cancer is without any doubt the malignancy with the poorest prognosis and the lowest survival rate. This highly aggressive disease is rarely diagnosed at an early stage and difficult to treat due to its resistance to radiotherapy and chemotherapy. Therefore, there is an urgent need to clarify the causes responsible for pancreatic cancer and to identify preventive strategies to reduce its incidence in the population. Some circumstances, such as smoking habits, being overweight and diabetes, have been identified as potentially predisposing factors to pancreatic cancer, suggesting that diet might play a role. A diet low in fat and sugars, together with a healthy lifestyle, regular exercise, weight reduction and not smoking, may contribute to prevent pancreatic cancer and many other cancer types. In addition, increasing evidence suggests that some food may have chemo preventive properties. Indeed, a high dietary intake of fresh fruit and vegetables has been shown to reduce the risk of developing pancreatic cancer, and recent epidemiological studies have associated nut consumption with a protective effect against it. Therefore, diet could have an impact on the development of pancreatic cancer and further investigations are needed to assess the potential chemo preventive role of specific foods against this disease. This review summarizes the key evidence for the role of dietary habits and their effect on pancreatic cancer and focuses on possible mechanisms for the association between diet and risk of pancreatic cancer.

  1. Ethical considerations in cardiovascular prevention.

    Science.gov (United States)

    Follath, F

    2009-12-01

    The fundamental values in medical ethics include the following aspects of professional conduct: (i) actions in the best interest of patients; (ii) first, do no harm; (iii) patients' right to refuse or choose treatments; (iv) fairness and equality in the distribution of healthcare resources; and (v) truthfulness and honesty (informed consent). These values have to be considered in all diagnostic steps and therapeutic decisions. They should also form the basis for discussions of potential conflicts of interest among patients, doctors, healthcare financers and politicians. Cardiovascular (CV) diseases represent the most frequent cause of death and a major healthcare problem in most regions of the world. CV prevention is therefore an important task both in individual subjects and as a means to improve health in the general population. While the merits of treatment in patients with established CV diseases, i.e. secondary prevention, are widely accepted and regarded as necessary, primary prevention with drugs in apparently healthy individuals at an increased risk of future CV events is not free of controversies. The different types of prevention envisaged also give rise to ethical questions: Should all the growing number of classical and newly recognised CV risk markers be a reason for intervention or should they be preferably used for calculating a total risk score? What are the compelling or only relative indications for anti-hypertensive, cholesterol-lowering, anti-diabetic or platelet-inhibiting drugs? Are pre-hypertension, pre-diabetes and marginally elevated cholesterol levels early diseases justifying drug treatment, regardless of the possibility that some prophylactic interventions may be associated with adverse events? Discussions also often arise concerning the role of age, gender and of non-CV co-morbidities for decisions about long-term prevention with drugs. How reliable and applicable are 'evidence-based' guidelines derived from trials in highly selected

  2. Childhood obesity, prevalence and prevention

    Directory of Open Access Journals (Sweden)

    Merchant Anwar T

    2005-09-01

    Full Text Available Abstract Childhood obesity has reached epidemic levels in developed countries. Twenty five percent of children in the US are overweight and 11% are obese. Overweight and obesity in childhood are known to have significant impact on both physical and psychological health. The mechanism of obesity development is not fully understood and it is believed to be a disorder with multiple causes. Environmental factors, lifestyle preferences, and cultural environment play pivotal roles in the rising prevalence of obesity worldwide. In general, overweight and obesity are assumed to be the results of an increase in caloric and fat intake. On the other hand, there are supporting evidence that excessive sugar intake by soft drink, increased portion size, and steady decline in physical activity have been playing major roles in the rising rates of obesity all around the world. Consequently, both over-consumption of calories and reduced physical activity are involved in childhood obesity. Almost all researchers agree that prevention could be the key strategy for controlling the current epidemic of obesity. Prevention may include primary prevention of overweight or obesity, secondary prevention or prevention of weight regains following weight loss, and avoidance of more weight increase in obese persons unable to lose weight. Until now, most approaches have focused on changing the behaviour of individuals in diet and exercise. It seems, however, that these strategies have had little impact on the growing increase of the obesity epidemic. While about 50% of the adults are overweight and obese in many countries, it is difficult to reduce excessive weight once it becomes established. Children should therefore be considered the priority population for intervention strategies. Prevention may be achieved through a variety of interventions targeting built environment, physical activity, and diet. Some of these potential strategies for intervention in children can be

    Diabetes-induced oxidative stress plays a critical role in the mobilisation of endothelial progenitor cells (EPCs) from the bone marrow to the circulation.This study was designed to explore the effects of chronic melatonin administration on the promotion of the mobilisation of EPCs and on the preservation of erectile function in type Ⅰ diabetic rats.Melatonin was administered to streptozotocin-induced type Ⅰdiabetic rats.EPCs levels were determined using flow cytometry,Oxidative stress in the bone marrow was indicated by the levels of superoxide dismutase and malondialdehyde.Erectile function was evaluated by measuring the intracavemous pressure during an electrostimulation of the cavernous nerve.The density of the endothelium and the proportions of smooth muscle and collagen in the corpus cavernosum were determined by immunohistochemistry.The administration of melatonin increased the superoxide dismutase level and decreased the malondiaidehyde level in the bone marrow,This effect was accompanied by an increased level of circulating EPCs in the diabetic rats.The intracavernous pressure to mean arterial pressure ratio of the rats in the treatment group was significantly greater,compared with diabetic control rats.The histological analysis demonstrated an increase in the endothelial density of the corpus cavernosum after the administration of melatonin.However,melatonin treatment did not change the proportions of smooth muscle and collagen in the corpus cavernosum of diabetic rats.Chronic administration of melatonin has a beneficial effect on preventing erectile dysfunction (ED) in type Ⅰ diabetic rats.Promoting the mobilisation of EPCs is one of the possible mechanisms involved in the improvement of ED.

    The memorandum of the research funding of prevention has been devised within the framework of the Prevention Research Funding Programme of the Federal Ministry of Education and Research. It consists not only of the obtained findings of the research-practice co-operation but also of recommendations for the implementation of prospective, innovational, effective, practice-oriented and sustainable research. The respective knowledge has been acquired from quantitative surveys on the experiences of scientists and practice partners within the prevention research funding project as well as from extensive qualitative methods of structured group evaluation. A participatory co-operation between research and practice based on mutual respect, trust and recognition is seen as mandatory for the further development of both prevention and health promotion research. Research and practice partners are required to engage in an ab initio collaboration starting from the conception phase, whereby it is advisable to encourage and fortify the communication between research, practice and funding partners by systematic surveillance in form of a meta-project. In addition, the inclusion of the target population from the outset and on a collaborative basis is considered as beneficial in order to ensure the practical application of the research findings. Furthermore, innovatory research designs which are able to provide a framework for internal flexibility, continuous re-assessment and adjustment are fundamental for the implementation of practice-oriented research. Moreover, a dynamic co-operation between different groups of interest not only depends on sharing responsibility but also on sufficient funding for both research and practice, which is particularly important for the transfer and communication of the attained findings. With regard to the evaluation of both effectiveness and sustainability of interventions, a research funding project is required which makes long-term results possible

    Full Text Available Health political background: In 2006, the prevalence of overweight and adiposity among children and adolescents aged three to 17 years is 15%, 6.3% (800,000 of these are obese. Scientific background: Obese children and adolescents have an increased body fat ratio. The reasons for overweight are – among others – sociocultural factors, and a low social status as determined by income and educational level of the parents. The consequences of adiposity during childhood are a higher risk of metabolic and cardiovascular diseases and increased mortality in adulthood. Possible approaches to primary prevention in children and adolescents are measures taken in schools and kindergarten, as well as education and involvement of parents. Furthermore, preventive measures geared towards changing environmental and living conditions are of particular importance. Research questions: What is the effectiveness and efficiency of different measures and programs (geared towards changing behaviour and environmental and living conditions for primary prevention of adiposity in children and adolescents, with particular consideration of social aspects? Methods: The systematic literature search yielded 1,649 abstracts. Following a two-part selection process with predefined criteria 31 publications were included in the assessment. Results: The majority of interventions evaluated in primary studies take place in schools. As the measures are mostly multi-disciplinary and the interventions are often not described in detail, no criteria of success for the various interventions can be extrapolated from the reviews assessed. An economic model calculation for Australia, which compares the efficiency of different interventions (although on the basis of low evidence comes to the conclusion that the intervention with the greatest impact on society is the reduction of TV-ads geared towards children for foods and drinks rich in fat and sugar.

    Nutritional rickets remains a public health concern in many areas of the world despite cheap and effective means of preventing the disease. The roles of vitamin D deficiency, low dietary calcium intakes and the interrelationships between the two in the pathogenesis of the disease are discussed. It is now recognized that vitamin D deficiency in the pregnant and lactating mother predisposes to the development of rickets in the breastfed infant, and that cultural and social factors are important in the pathogenesis of the disease during the adolescent growth spurt. Prevention of rickets is dependent on the awareness of the medical profession and the general public of the need to ensure adequate intakes of vitamin D in at-risk populations, and of the importance of increasing dietary intakes of calcium using locally available and inexpensive foods in communities in which dietary calcium deficiency rickets is prevalent.

    Prevention of cancer remains the most promising strategy for reducing both its incidence and the mortality due to this disease. For more than four decades, findings from epidemiology, basic research and clinical trials have informed the development of lifestyle and medical approaches to cancer prevention. These include selective oestrogen receptor modulators and aromatase inhibitors for breast cancer, the 5-α-reductase inhibitors finasteride and dutasteride for prostate cancer, and the development of vaccines for viruses that are associated with specific cancers. Future directions include genetic, proteomic and other molecular approaches for identifying pathways that are associated with cancer initiation and development, as well as refining the search for immunologically modifiable causes of cancer.

    This plan serves as the principal crosscutting guidance to Department of Energy (DOE) Headquarters, Operations Office, laboratory, and contractor management to fully implement pollution prevention programs within the DOE complex between now and 2000. To firmly demonstrate DOE's commitment to pollution prevention, the Secretary of Energy has established goals, to be achieved by December 31, 1999, that will aggressively reduce DOE's routine generation of radioactive, mixed, and hazardous wastes, and total releases and offsite transfers of toxic chemicals. The Secretary also has established sanitary waste reduction, recycling, and affirmative procurement goals. Site progress in meeting these goals will be reported annually to the Secretary in the Annual Report on Waste Generation and Waste Minimization Progress, using 1993 as the baseline year. Implementation of this plan will represent a major step toward reducing the environmental risks and costs associated with DOE operations

    2007-01-01

    Visual cryptography (VC) is a method of encrypting a secret image into shares such that stacking a sufficient number of shares reveals the secret image. Shares are usually presented in transparencies. Each participant holds a transparency. Most of the previous research work on VC focuses on improving two parameters: pixel expansion and contrast. In this paper, we studied the cheating problem in VC and extended VC. We considered the attacks of malicious adversaries who may deviate from the scheme in any way. We presented three cheating methods and applied them on attacking existent VC or extended VC schemes. We improved one cheat-preventing scheme. We proposed a generic method that converts a VCS to another VCS that has the property of cheating prevention. The overhead of the conversion is near optimal in both contrast degression and pixel expansion.

    Unlike other natural hazards, earthquakes strike suddenly and without warning. Consequently, prevention is the best we can do to ensure safety. In spite of the large and medium earthquakes, some of them tsunamigenic, that affected Portugal in the past, the Portuguese society is little aware of the seismic risk and has not developed an adequate culture of prevention. This is most probably due to the long time interval between destructive earthquakes. Earthquakes can be a real danger to societies, damaging human-made structures and endangering human lives. Earthquakes can trigger additional emergencies, and individuals should also be prepared to contend with it. By planning and practicing what to do if an earthquake strikes, children and their family can learn to react correctly and automatically when the shaking begins. Risks can then be dramatically lessened if the population is educated on how to react before, during and after an earthquake. Children's knowledge is ever growing. They have a fundamental role in changing societies. By educating the children of today we are forming better adults of tomorrow. We are simultaneously passing this knowledge to their caregivers and families. Through demonstrating how fundamental it is to be conscious of those issues, not only will the children will be informed, but also their relatives will be aware of such risks. We use this approach to explain children how to assess risk in a broader sense. We teach them other preventive measures, namely those related with electricity, gas and the danger on non-potable water, essential topics on "what to do before an earthquake" but also on the daily routines. This presentation will highlight the importance of encouraging a culture of prevention. This project funded by the Portuguese "Ciência Viva" program, and is conducted by science high-school students, teachers and the parents association. Scientific support is given by the seismology research group at Instituto Dom Luíz.

    Full Text Available Stroke secondary prevention in internist practice is discussed in accordance with up to date guidelines. Modern pharmacotherapy includes antiaggregants or anticoagulants, statins, and antihypertensive drugs. The choice of drugs is mostly founded on the rules of evidence based medicine, which allow adjusting individual treatment depending on clinical conditions. The composition of perindopril and indapamide is a preferred nowadays combination of antihypertensive drugs.

    2013-08-16

    The Waitemata Hypertension Clinic Database 2009-2012 (Auckland, New Zealand) was searched for patients meeting the definition of Malignant Hypertension. Eighteen of 565 patients met the criteria. All patients had essential hypertension which was either undiagnosed, untreated or undertreated. Most cases responded satisfactorily to standard drug therapy, but a number were left with significant chronic kidney disease. Malignant hypertension is a life-threatening disease which should be entirely preventable with regular blood pressure checks in primary care.

  3. A performative definition of waste prevention.

    Science.gov (United States)

    Corvellec, Hervé

    2016-06-01

    The increasing importance being placed on waste prevention in European waste governance raises the question of how waste prevention is defined in practice. This paper presents a qualitative analysis of a sample of fifty-one Swedish waste prevention initiatives with the purpose of identifying which kind of actions are imagined, promoted, and set into motion under the label of waste prevention. The analysis shows that despite their apparent variety, the initiatives in the sample boil down to three main types of actions: raising awareness about the need to prevent waste, increasing material efficiency, and developing sustainable consumption. In contradistinction to the formal definition of waste prevention in the European Waste Framework Directive (2008/98/EC), what emerges from analyzing the initiatives in the sample is a performative definition of waste prevention as something heterogeneous, contradictory, and evolving. Such a definition of waste prevention in practice provides an understanding of the organizational dynamics of waste prevention.

  4. New technology for accident prevention

    2006-07-01

    This power point presentation examined the effects of fatigue in the workplace and presented 3 technologies designed to prevent or monitor fatigue. The relationship between mental fatigue, circadian rhythms and cognitive performance was explored. Details of vigilance related degradations in the workplace were presented, as well as data on fatigue-related accidents and a time-line of meter-reading errors. It was noted that the direct cause of the Exxon Valdez disaster was sleep deprivation. Fatigue related accidents during the Gulf War were reviewed. The effects of fatigue on workplace performance include impaired logical reasoning and decision-making; impaired vigilance and attention; slowed mental operations; loss of situational awareness; slowed reaction time; and short cuts and lapses in optional or self-paced behaviours. New technologies to prevent fatigue-related accidents include (1) the driver fatigue monitor, an infra-red camera and computer that tracks a driver's slow eye-lid closures to prevent fatigue related accidents; (2) a fatigue avoidance scheduling tool (FAST) which collects actigraphs of sleep activity; and (3) SAFTE, a sleep, activity, fatigue and effectiveness model. refs., tabs., figs.

    Full Text Available "nThe dysesthesia and paresthesia that occurs in laboratory rats after spinal cord injury (SCI results in autophagia. This self-destructive behavior interferes with functional assessments in designed studies and jeopardizes the health of the injured rat. In this study, we evaluated role of saturated picric acid in the prevention of autophagia and self-mutilation. All rats were anesthetized with an intraperitoneal injection of a mixture of ketamine (100 mg/kg and xylazine (10 mg/kg for the SCI procedures. In the first 39 rats, no solution applied to the hind limbs, but in the next 26 cases, we smeared the saturated picric acid on the tail, lower extremities, pelvic, and abdomen of the rats immediately after SCI. In the rats without picric acid, 23 rats died following autophagia, but in the 26 rats with picric acid, there was no autophagia (P < 0.001. Picric acid side effects in skin and gastrointestinal signs such as irritation, redness and diarrhea were not seen in any rat. Saturated picric acid is a topical solution that if used appropriately and carefully, might be safe and effectively prevents autophagia and self-mutilation. When the solution is applied to the lower abdomen and limbs, we presume that its bitterness effectively prevents the rat from licking and biting the limb.

  6. Prevention of inadvertent perioperative hypothermia.

    Science.gov (United States)

    Burger, Leona; Fitzpatrick, Jane

    All patients undergoing surgery are at risk of developing hypothermia; up to 70% develop hypothermia perioperatively. Inadvertent hypothermia is associated with complications such as impaired wound healing, increased blood loss, cardiac arrest and increased risk of wound infection. Anaesthesia increases the risk as the normal protective shivering reflex is absent. Ambient temperature also has a major effect on the patient's body temperature. Prevention of hypothermia not only reduces the incidence of complications, but patients also experience a greater level of comfort, and avoid postoperative shivering and the unpleasant sensation of feeling cold. Nurses should be aware of the risks of hypothermia so that preventative interventions can be employed to minimize the risk of hypothermia. Preoperative assessment is essential to enable identification of at-risk patients. Simple precautionary measures initiated by nurses can considerably reduce the amount of heat lost, minimize the risk of associated complications and ultimately improve patients' short- and long-term recovery. Minimizing skin exposure, providing adequate bed linen for the transfer to theatre and educating patients about the importance of keeping warm perioperatively are all extremely important. It is also worth considering using forced-air warmers preoperatively as research suggests that initiating active warming preoperatively may be successful in preventing hypothermia during the perioperative period.

  7. Type 1 diabetes pathogenesis - Prevention???

    C S Muralidhara Krishna

    2015-01-01

    Full Text Available Pathogenesis of type 1 diabetes is multi-faceted, including, autoimmunity, genetics and environment. Autoimmunity directed against pancreatic islet cells results in slowly progressive selective beta-cell destruction ("Primary autoimmune insulitis", culminating over years in clinically manifested insulin-dependent diabetes mellitus (IDDM. Circulating serum autoantibodies directed against the endocrine cells of the islets of Langerhans (Islet cell autoantibodies - ICAb are an important hallmark of this disease. Assays for islet cell autoantibodies have facilitated the investigation and understanding of several facets in the pathogenesis of autoimmune diabetes. Their applications have extended into clinical practice and have opened new avenues for early preclinical prediction and preventive prophylaxis in IDDM/type 1 DM. Recently, surprisingly, differences in insulin content between T1DM islets, as well as, ′patchy′ or ′lobular′ destruction of islets have been described. These unique pathobiological phenomena, suggest that beta cell destruction may not always be inexorable and inevitably complete/total, and thus raise hopes for possible therapeutic interruption of beta cell autoimmunity - destruction and cure of type 1 diabetes. "Recurrent or secondary autoimmune insulitis" refers to the rapid reappearance of islet cell autoantibodies post pancreas transplant, and selective islet beta cell destruction in the grafted pancreas [never forgetting or "anamnestic" beta cell destructive memory], in the absence of any graft pancreas rejection [monozygotic twin to twin transplantation]. The one definite environmental factor is congenital rubella, because of which a subset of children subsequently develop type 1 diabetes. The putative predisposing factors are viruses, gluten and cow′s milk. The putative protective factors include gut flora, helminths, viral infections, and Vitamin D. Prevention of T1DM can include: Primary prevention strategies

  17. Hepatocellular carcinoma: Therapy and prevention

    Institute of Scientific and Technical Information of China (English)

    Hubert E Blum

    2005-01-01

    Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. The major etiologies and risk factors for the development of HCC are well defined and some of the multiple steps involved in hepatocarcinogenesis have been elucidated in recent years. Despite these scientific advances and the implementation of measures for the early detection of HCC in patients at risk, patient survival has not improved during the last three decades. This is due to the advanced stage of the disease at the time of clinical presentation and limited therapeutic options. The therapeutic options fall into five main categories: surgical interventions including tumor resection and liver transplantation, percutaneous interventions including ethanol injection and radiofrequency thermal ablation, transarterial interventions including embolization and chemoembolization, radiation therapy and drugs as well as gene and immune therapies. These therapeutic strategies have been evaluated in part in randomized controlled clinical trials that are the basis for therapeutic recommendations. Though surgery, percutaneous and transarterial interventions are effective in patients with limited disease (1-3 lesions, <5 cm in diameter) and compensated underlying liver disease (cirrhosis Child A), at the time of diagnosis more than 80% patients present with multicentric HCC and advanced liver disease or comorbidities that restrict the therapeutic measures to best supportive care. In order to reduce the morbidity and mortality of HCC, early diagnosis and the development of novel systemic therapies for advanced disease, including drugs, gene and immune therapies as well as primary HCC prevention are of paramount importance. Furthermore, secondary HCC prevention after successful therapeutic interventions needs to be improved in order to make an impact on the survival of patients with HCC. New technologies, including gene expression profiling and proteomic analyses, should allow to further

  18. Pollution Prevention Program: Technology summary

    International Nuclear Information System (INIS)

    The Department of Energy (DOE) has established a national Research, Development, Demonstration, Testing, and Evaluation (RDDT ampersand E) Program for pollution prevention and waste minimization at its production plants During FY89/90 the Office of Environmental Restoration and Waste Management (EM), through the Office of Technology Development (OTD), established comprehensive, pollution prevention technical support programs to demonstrate new, environmentally-conscious technology for production processes. The RDDT ampersand E program now entails collaborative efforts across DOE. The Pollution Prevention Program is currently supporting three major activities: The DOE/US Air Force Memorandum of Understanding Program is a collaborative effort to utilize the combined resources of DOE and the Department of Defense, eliminate duplication of effort in developing technologies, and to facilitate technology solutions aimed at reducing waste through process modification, material substitution or recycling. The Waste Component Recycle, Treatment and Disposal Integrated Demonstration (WeDID) will develop recycle, treatment, and disposal processes and associated technologies for use in the dismantlement of non-nuclear weapons components, to support US arms treaties and policies. This program will focus on meeting all security and regulatory requirements (with additional benefit to the commercial electronics industry). The Environmentally Conscious Manufacturing Integrated Demonstration (ECMID) will effectively implement ECM technologies that address both the needs of the DOE Complex and US electronics industry, and encourage strong interaction between DOE and US industry. The ECMID will also develop life cycle analysis tools that will aid decisionmakers in selecting the optimum process based on the tradeoffs between cost an environmental impact

    Human papilloma virus (HPV) is the most common sexually transmitted disease in the world. Almost 80% of the world's population is exposed by the age of 50. HPV can cause oropharyngeal, genital, and anal cancers. It also causes genital warts. There is no cure for HPV but vaccines are available to prevent infection by the most common HPV viruses; unfortunately, usage is low. Most people will clear HPV spontaneously. Those who do not are at high risk for developing malignancy. Treatment mainstays are destruction and excision of the lesions. PMID:22828099

    Full Text Available Hepatitis B is one of the most common infectious diseases globally. The prevalence of chronic hepatitis B virus (HBV infection varies geographically, from high (>8%, intermediate (2-7% to low (<2% prevalence. The predominant routes of transmission vary according to the endemicity of the HBV infection. In areas with high HBV endemicity, perinatal transmission is the main route of transmission, whereas in areas with low HBV endemicity, sexual contact amongst high-risk adults and using shared needles amongst injection drug users are the predominant route. Three main strategies have been approved to be effective in preventing HBV infection. They are behavior modification, passive immunoprophylaxis, and active immunization.

  2. Oral cleft prevention program (OCPP

    Directory of Open Access Journals (Sweden)

    Wehby George L

    2012-11-01

    Full Text Available Abstract Background Oral clefts are one of the most common birth defects with significant medical, psychosocial, and economic ramifications. Oral clefts have a complex etiology with genetic and environmental risk factors. There are suggestive results for decreased risks of cleft occurrence and recurrence with folic acid supplements taken at preconception and during pregnancy with a stronger evidence for higher than lower doses in preventing recurrence. Yet previous studies have suffered from considerable design limitations particularly non-randomization into treatment. There is also well-documented effectiveness for folic acid in preventing neural tube defect occurrence at 0.4 mg and recurrence with 4 mg. Given the substantial burden of clefting on the individual and the family and the supportive data for the effectiveness of folic acid supplementation as well as its low cost, a randomized clinical trial of the effectiveness of high versus low dose folic acid for prevention of cleft recurrence is warranted. Methods/design This study will assess the effect of 4 mg and 0.4 mg doses of folic acid, taken on a daily basis during preconception and up to 3 months of pregnancy by women who are at risk of having a child with nonsyndromic cleft lip with/without palate (NSCL/P, on the recurrence of NSCL/P. The total sample will include about 6,000 women (that either have NSCL/P or that have at least one child with NSCL/P randomly assigned to the 4 mg and the 0.4 mg folic acid study groups. The study will also compare the recurrence rates of NSCL/P in the total sample of subjects, as well as the two study groups (4mg, 0.4 mg to that of a historical control group. The study has been approved by IRBs (ethics committees of all involved sites. Results will be disseminated through publications and presentations at scientific meetings. Discussion The costs related to oral clefts are high, including long term psychological and socio-economic effects. This study

    1994-08-01

    Penetrating wounds, stings, and inoculation of venom are common marine injuries to unwary walkers during the summer season. In many circumstances, foreign bodies such as wood splinters or small shards of glass can be removed readily with fine-pointed forceps. Other times, objects may not be noticed until radiographic examination of the injured area. With deeply penetrated foreign bodies, attempts at removal must often be weighed against the likelihood of continued symptoms and damage should the object be left in the foot. This review presents methods of prevention and treatment for common sources of marine foot injuries. PMID:7997347

  1. Relapse prevention for addictive behaviors

    Directory of Open Access Journals (Sweden)

    George William H

    2011-07-01

    Full Text Available Abstract The Relapse Prevention (RP model has been a mainstay of addictions theory and treatment since its introduction three decades ago. This paper provides an overview and update of RP for addictive behaviors with a focus on developments over the last decade (2000-2010. Major treatment outcome studies and meta-analyses are summarized, as are selected empirical findings relevant to the tenets of the RP model. Notable advances in RP in the last decade include the introduction of a reformulated cognitive-behavioral model of relapse, the application of advanced statistical methods to model relapse in large randomized trials, and the development of mindfulness-based relapse prevention. We also review the emergent literature on genetic correlates of relapse following pharmacological and behavioral treatments. The continued influence of RP is evidenced by its integration in most cognitive-behavioral substance use interventions. However, the tendency to subsume RP within other treatment modalities has posed a barrier to systematic evaluation of the RP model. Overall, RP remains an influential cognitive-behavioral framework that can inform both theoretical and clinical approaches to understanding and facilitating behavior change.

  2. Method of preventing filter contamination

    International Nuclear Information System (INIS)

    Since slight amounts of radioactive corrosion products and soluble ions are contained in condensates produced from a nuclear reactor, they are cleaned-up in a filtration desalter, desalter, etc. before returning to the reactor. Hollow fibrous membrane filters are disposed instead of the filtration desalter for eliminating only the solid contents. When polymeric material such as the hollow fibrous membrance filters are put into contact with purified water of low conductivity, electrostatic charges are accumulated at the interface between them. If the membranes have negative static charges, Fe ions are attracted to increase the Fe ion concentration at the membrane boundary. If they are oxidized with oxygen dissolved in water, ferric hydroxide of low solubility is formed as precipitates. Then, oxidizer, in particular, hydrogen peroxide is added depending on the Fe ion concentration in flowing water entering the filters, to prevent the deposition of the Fe ions. This can prevent clogging in the filters and increase in the differential pressure due to the clogging. (T.M.)

  3. Modeling accidents for prioritizing prevention

    International Nuclear Information System (INIS)

    The Workgroup Occupational Risk Model (WORM) project in the Netherlands is developing a comprehensive set of scenarios to cover the full range of occupational accidents. The objective is to support companies in their risk analysis and prioritization of prevention. This paper describes how the modeling has developed through projects in the chemical industry, to this one in general industry and how this is planned to develop further in the future to model risk prevention in air transport. The core modeling technique is based on the bowtie, with addition of more explicit modeling of the barriers needed for risk control, the tasks needed to ensure provision, use, monitoring and maintenance of the barriers, and the management resources and tasks required to ensure that these barrier life cycle tasks are carried out effectively. The modeling is moving from a static notion of barriers which can fail, to seeing risk control dynamically as (fallible) means for staying within a safe envelope. The paper shows how concepts develop slowly over a series of projects as a core team works continuously together. It concludes with some results of the WORM project and some indications of how the modeling is raising fundamental questions about the conceptualization of system safety, which need future resolution

  4. Vitamin D in dementia prevention.

    2016-03-01

    Beyond effects on bone health, vitamin D exerts effects on a variety of target organs, including the brain. The discussion herein presents the state of the art in research on the neurological role of vitamin D and clinical implications among older adults, including implications for dementia onset and progression. Some of the neurosteroid actions of vitamin D include regulation of calcium homeostasis, clearance of amyloid-β peptide, antioxidant and anti-inflammatory effects, and possible protection against the neurodegenerative mechanisms associated with Alzheimer's disease (AD). The correction of age-related hypovitaminosis D and cognitive decline has been reported by various cross-sectional and longitudinal studies reporting associations of lower vitamin D concentrations with brain changes and poorer cognition, specifically with respect to executive dysfunction. Epidemiological studies have consistently shown an association between inadequate dietary intake of vitamin D and cognitive disorders, including greater AD risk. Although there have not been any randomized placebo-controlled trials conducted to examine the effectiveness of vitamin D supplementation to prevent AD, several nonrandomized controlled studies have found that older adults experienced cognitive improvements after 1-15 months of vitamin D supplementation. Therefore, it appears crucial to maintain vitamin D concentrations at sufficiently high levels in order to slow, prevent, or improve neurocognitive decline. PMID:27116242

    1994-12-01

    The waste generated by DOE facilities is a serious problem that significantly impacts current operations, increases future waste management costs, and creates future environmental liabilities. Pollution Prevention (P2) emphasizes source reduction through improved manufacturing and process control technologies. This concept must be incorporated into DOE`s overall operating philosophy and should be an integral part of Total Quality Management (TQM) program. P2 reduces the amount of waste generated, the cost of environmental compliance and future liabilities, waste treatment, and transportation and disposal costs. To be effective, P2 must contribute to the bottom fine in reducing the cost of work performed. P2 activities at LLNL include: researching and developing innovative manufacturing; evaluating new technologies, products, and chemistries; using alternative cleaning and sensor technologies; performing Pollution Prevention Opportunity Assessments (PPOAs); and developing outreach programs with small business. Examples of industrial outreach are: innovative electroplating operations, printed circuit board manufacturing, and painting operations. LLNL can provide the infrastructure and technical expertise to address a wide variety of industrial concerns.

    Thermoplastic film added to proppants is effective and economical for preventing proppant flowback after an hydraulic fracturing treatment. Most other methods, such as resin-coated proppant and fiber, for controlling proppant flowback have drawbacks that added to treatment costs by requiring long downtime, costly additives, or frequent equipment replacement. Thermoplastic film does not react chemically with fracturing fluids. After the proppant is placed in the fracture, the film strips intertwine with the proppant grains or at higher temperatures, the strips become adhesive and shrink forming consolidated clusters that hold open the newly created fractures and prevent proppant from flowing back. The low cost of the film means that the strips can be used throughout the fracturing job or in selected stages. The strips are compatible with fracturing fluid chemistry, including breakers and crosslinkers, and can be used in wells with a wide range of bottom hole temperatures. The end result is a well that can be brought back on-line in a short time with little proppant flowback. This paper reviews the cost benefits and performance of these proppants.

  7. Crisis management and crisis prevention

    International Nuclear Information System (INIS)

    This paper reports that many proposals have come forth to ease the tension between East and West. Some focus on arms developments, others take up diplomatic issues. In addition, some have raised the question of crisis management and crisis prevention. Can crises be prevented even before they have taken place? The Palme Commission on Disarmament and Security suggested, in its 1982 report, ways of restraining superpower involvement in Third World conflicts. Such conflicts, it was argued, could escalate and ultimately result in nuclear confrontation between the United States and the Soviet Union. Certainly, the commission also paid attention to conflicts over issues in Europe and to problems in Eastern or in Western Europe. However, the commission raised a question that lately has received increasing attention: the dangers of superpower confrontation over Third World issues. In his statement to the United Nations on 24 October 1985, President Regan pointed to the need for settling regional conflicts as they play a large role in building suspicions and tensions. Regan's initiative explicitly concerned Afghanistan, Cambodia, Ethiopia, Angola and Nicaragua. It included negotiations with the Soviet Union over Afghanistan, and, at a later stage, also over other issues. The goal, he the, was not to force a settlement on the parties. The initiative concerned issues that have for the American public, justified armaments and reduced Soviet credibility

  8. Prevention of pelvic radiation disease

    2015-01-01

    Pelvic cancers are among the most frequently diagnosed cancers worldwide. Treatment of patients requires a multidisciplinary approach that frequently includes radiotherapy. Gastrointestinal(GI) radiation-induced toxicity is a major complication and the transient or long-term problems, ranging from mild to very severe, arising in non-cancerous tissues resulting from radiation treatment to a tumor of pelvic origin, are actually called as pelvic radiation disease. The incidence of pelvic radiation disease changes according to the radiation technique, the length of follow up, the assessmentmethod, the type and stage of cancer and several other variables. Notably, even with the most recent radiation techniques, i.e., intensity-modulated radiotherapy, the incidence of radiation-induced GI side effects is overall reduced but still not negligible. In addition, radiation-induced GI side effects can develop even after several decades; therefore, the improvement of patient life expectancy will unavoidably increase the risk of developing radiation-induced complications. Once developed, the management of pelvic radiation disease may be challenging. Therefore, the prevention of radiation-induced toxicity represents a reasonable way to avoid a dramatic drop of the quality of life of these patients. In the current manuscript we provide an updated and practical review on the best available evidences in the field of the prevention of pelvic radiation disease.

    Adolescents are unique for tobacco control. They are easy to become tobacco-addicted and more than 70 % of adult smokers start to smoke tobacco during adolescence. Therefore, they are good targets for sales campaign by tobacco industry to secure their profit by making a large reservoir of smokers. Tobacco industry's tactics are very ingenious. It conducts many kinds of hidden advertisement. It supports many activities of youth and nonprofit organizations. Therefore, our effort should also put targets on adolescents. Adolescence is a unique stage of development and it is important to know its characteristics for effective approach to prevent starting and to facilitate quitting smoking. It is important to make tobacco-free environment surrounding adolescents, such as school campuses and other public places. PMID:23631250

  12. Magnesium in Prevention and Therapy

    Gröber, Uwe; Schmidt, Joachim; Kisters, Klaus

    2015-01-01

    Magnesium is the fourth most abundant mineral in the body. It has been recognized as a cofactor for more than 300 enzymatic reactions, where it is crucial for adenosine triphosphate (ATP) metabolism. Magnesium is required for DNA and RNA synthesis, reproduction, and protein synthesis. Moreover, magnesium is essential for the regulation of muscular contraction, blood pressure, insulin metabolism, cardiac excitability, vasomotor tone, nerve transmission and neuromuscular conduction. Imbalances in magnesium status—primarily hypomagnesemia as it is seen more common than hypermagnesemia—might result in unwanted neuromuscular, cardiac or nervous disorders. Based on magnesium’s many functions within the human body, it plays an important role in prevention and treatment of many diseases. Low levels of magnesium have been associated with a number of chronic diseases, such as Alzheimer’s disease, insulin resistance and type-2 diabetes mellitus, hypertension, cardiovascular disease (e.g., stroke), migraine headaches, and attention deficit hyperactivity disorder (ADHD).

  14. Prevention of retinopathy of prematurity

    João Borges Fortes Filho

    2011-06-01

    Full Text Available Retinopathy of prematurity (ROP is related to oxygen-regulated vascular endothelial growth factor and to insulin-like growth factor-I. After premature birth, supplemental oxygen induces a retinal hyperoxic condition with vasoconstriction and to a definitive interruption of retinal vasculogenesis. Peripheral ischemia may stimulate retinal neovascularization and the onset of additional ROP-related complications. The natural course of the disease may result in irreversible blindness if not promptly diagnosed and attended. Recently, a significant increase in the prevalence of ROP has been observed in survival rates of preterm infants, especially in emerging-economy countries in Latin America, Asia, and Eastern Europe. This article addresses the main preventive measures in ROP.

  15. THE BASIS FOR SPEECH PREVENTION

    Directory of Open Access Journals (Sweden)

    Jordan JORDANOVSKI

    1997-06-01

    Full Text Available The speech is a tool for accurate communication of ideas. When we talk about speech prevention as a practical realization of the language, we are referring to the fact that it should be comprised of the elements of the criteria as viewed from the perspective of the standards. This criteria, in the broad sense of the word, presupposes an exact realization of the thought expressed between the speaker and the recipient.The absence of this criterion catches the eye through the practical realization of the language and brings forth consequences, often hidden very deeply in the human psyche. Their outer manifestation already represents a delayed reaction of the social environment. The foundation for overcoming and standardization of this phenomenon must be the anatomy-physiological patterns of the body, accomplished through methods in concordance with the nature of the body.

  16. Skin tears: prevention and treatment.

    Wick, Jeannette Y; Zanni, Guido R

    2008-07-01

    While skin tears are common among the elderly in general, and residents of long-term care facilities in particular, there has been limited research into their treatment. Many facilities voluntarily track skin tears, and some states require facilities to report these events. Risk factors include age, xerosis (abnormal eye, skin, or mouth dryness), need for help in activities of daily living, presence of senile purpura, visual impairment, and poor nutrition. Plans to prevent skin tears that employ skin sleeves, padded side rails, gentle skin cleansers, moisturizing lotions, as well as staff education, can decrease by half the number of skin tears incurred in a long-term care facility. Although the treatment process seems simple, it is time consuming and can be painful for the patient. Residents with dementia or agitation often try to remove bulky dressings used to cover skin tears. Dressing changes may injure the fragile wound via skin stripping.

  17. Cardiovascular Prevention of Cognitive Decline

    Directory of Open Access Journals (Sweden)

    Jean-Jacques Monsuez

    2011-01-01

    Full Text Available Midlife cardiovascular risk factors, including diabetes, hypertension, dyslipemia, and an unhealthy lifestyle, have been linked to subsequent incidence, delay of onset, and progression rate of Alzheimer disease and vascular dementia. Conversely, optimal treatment of cardiovascular risk factors prevents and slows down age-related cognitive disorders. The impact of antihypertensive therapy on cognitive outcome in patients with hypertension was assessed in large trials which demonstrated a reduction in progression of MRI white matter hyperintensities, in cognitive decline and in incidence of dementia. Large-scale database correlated statin use and reduction in the incidence of dementia, mainly in patients with documented atherosclerosis, but clinical trials failed to reach similar conclusions. Whether a multitargeted intervention would substantially improve protection, quality of life, and reduce medical cost expenditures in patients with lower risk profile has not been ascertained. This would require appropriately designed trials targeting large populations and focusing on cognitive decline as a primary outcome endpoint.

    2015-01-01

    Metastatic disease is responsible for 90% of death from solid tumors. However, only a minority of metastasis-specific targets has been exploited therapeutically, and effective prevention and suppression of metastatic disease is still an elusive goal. In this review, we will first summarize the current state of knowledge about the molecular features of the disease, with particular focus on steps and targets potentially amenable to therapeutic intervention. We will then discuss the reasons underlying the paucity of metastatic drugs in the current oncological arsenal and potential ways to overcome this therapeutic gap. We reason that the discovery of novel promising targets, an increased understanding of the molecular features of the disease, the effect of disruptive technologies, and a shift in the current preclinical and clinical settings have the potential to create more successful drug development endeavors.

    Exposures and technologies in the workplace are changing due to a variety of factors, including newly developed technologies, mechanization and automation, and improvements in industrial hygiene primarily effected in many developed countries. In addition substitution and removal of carcinogenic constituents in the workplace and general environment are increasing in a number of instances, particularly in North America, Western Europe, and Japan, and they are being accompanied as well by remediation either by source reduction, recycling, or compliance to more stringent national and international regulations and standards. This overview highlights some of the strategies employed in the technological changes in cancer prevention and cites examples in source reduction, changes in formulation, product or process changes, recycling, and hazardous materials management.

    1995-01-01

    Hepatocellular carcinoma (HCC) is one of the major cancers in China. Accordingly, the mortality rates in 1990 (per 100,000) were 20.10 in certain cities and 24.32 in certain counties. More than 90% of HCC cases and 70% of controls were infected with the hepatitis B virus (HBV) (Odds Ratio (OR) = 10-50). In the same group of patients, 8-27% of those with HCC and 0-11% of the healthy controls were also infected with hepatitis C (HCV) (OR = 2.11-17.29). There appears to be some correlation between HBV markers and the OR. The government requires that 85% of infants be immunized with HBV vaccine. In 1992, there were 3 million infants inoculated with HB vaccines. Aflatoxins have been found as contaminants in food, particularly in corn, peanut oil, soya sauce and fermented soya beans. The intake of aflatoxin B1 (AFB1) by people of ten different villages correlated with HCC mortality rates (r = 0.55; P aflatoxins. These adducts are higher in hyperendemic HCC areas and cases. Most people have now changed their staple food and eat rice instead of corn. Six large epidemiological studies have confirmed that people who drink pond-ditch water experience higher HCC mortality rates than people who drink deep-well water. Recent research has found that the blue-green algal toxin microcystin (MCYST) was a contaminant of pond-ditch water. MCYST is a strong promoter of HCC and will induce severe intrahepatic haemorrhages and liver necrosis. More than 80% of people in Qidong County have already changed their sources of water from pond-ditches to deep wells. Therefore, a combined strategy of the prevention of hepatitis, control of crops and control of drinking water is advocated for the primary prevention of HCC in China.

  5. Counterforce applied to prevent spalling

    International Nuclear Information System (INIS)

    The field experiment within CAPS (Counterforce Applied to Prevent Spalling) was initiated to determine if the application of dry bentonite pellets is sufficient to suppress thermally-induced spalling in KBS-3 deposition holes. The experience gained from Aespoe Pillar Stability Experiment, conducted between 2002 and 2006, indicated that spalling could be controlled by the application of a small confining pressure in the deposition holes. The CAPS field experiment that included four pairs of boreholes with a diameter of approximately 0.5 m, was carried out as a series of demonstration experiments in the TASQ-tunnel. The first and second heating tests were performed in open holes, without any confining pressure on the borehole wall and the third and fourth heating tests with a confining pressure created by expanded clay pellets (LECA). The first heating test was initiated at the end of August 2008 and the final test was finished at the end of May 2009. The trials suggest that the small confining pressure offered by the LECA pellets was adequate to control spalling and prevent the formation of a highly conductive zone of fractured rock in the 500-mm-diameter holes. It is recommended that a full-scale test be carried out to assess if the findings are applicable to 1,750-mm-diameter deposition holes. Should the full scale tests support the findings from these initial trials, filling the gap between the bentonite blocks and rock wall with dry bentonite pellets will provide a viable engineered solution for controlling the effects of thermally induced spalling in the KBS-3 deposition holes

  7. New Fluid Prevents Railway Ice

    Science.gov (United States)

    2001-01-01

    Through a licensing agreement between NASA's Ames Research Center and Midwest Industrial Supply, Inc. (MIS), two MIS products have been enhanced with NASA's anti-icing fluid technology. MIS offers the new fluid in two commercial products, the Zero Gravity(TM) Third Rail Anti-Icer/Deicer and the Ice Free Switch(R). Using NASA's fluid technology, these products form a protective-coating barrier that prevents the buildup of ice and snow. Applying the fluid to the railway components prior to ice or snowstorm works as an anti-icing fluid, remaining in place to melt precipitation as it hits the surface. It also functions as a deicing fluid. If applied to an already frozen switch or rail, it will quickly melt the ice, free the frozen parts, and then remain in place to prevent refreezing. Additional benefits include the ability to cling to vertical rail surfaces and resist the effects of rain and wind. With the Ice Free Switch, it takes only five minutes to treat the switch by spraying, brushing, or pouring on the product. Ice Free Switch requires as little as one gallon per switch whereas other deicing fluids require five to ten gallons of liquid to effectively melt ice. Zero Gravity serves the same anti-icing/deicing purposes but applies fluid to the third rail through a system that is easily installed onto mass transit cars. A tank of fluid and a dispensing system are placed underneath the train car and the fluid is applied as the train runs its route.

    Psychosocial factors refer to all organizational factors and interpersonal relationships in the workplace that may affect the health of the workers. Currently, two psychosocial risk models are universally recognized for producing solid scientific knowledge regarding the vital link between social or psychological phenomena at work and the development of several diseases, such as cardiovascular diseases or depression. The first is the "job demand-contro-support" model, which was defined by Karasek and to which the concept of social support has been added; the second is the "effort/reward imbalance" model defined by Siegrist. The public health perspective calls for theoretical models based on certain psychosocial attributes of the work environment for which there is empirical evidence of their pathogenic potential for exposed workers. Not only do these models reduce the complexity of the psychosocial reality of the work to components that are significant in terms of health risks, but they also facilitate the development and implementation of workplace interventions. Psychosocial risk intervention strategies currently implemented by companies are predominantly individual-oriented and aim chiefly at reducing the effects of stressful work situations by improving individual ability to adapt to the situation and manage stress. Like personal protection equipment for exposure to physical or chemical risks, these secondary prevention measures are commendable but insufficient, because they aim to reduce only the symptoms and not the cause of problems. Any intervention program for these risks should necessarily include a primary prevention component with a view to eliminating, or at least reducing, the psychosocial pathogenic agents in the workplace. Several authors have suggested that well-structured organizational approaches are most effective and should generate more important, longer-lasting effects than individual approaches. However, the evidence should be strengthened by

  12. Guideline Implementation: Prevention of Retained Surgical Items.

    Fencl, Jennifer L

    2016-07-01

    A surgical item unintentionally retained in a patient after an operative or other invasive procedure is a serious, preventable medical error with the potential to cause the patient great harm. Perioperative RNs play a key role in preventing retained surgical items (RSIs). The updated AORN "Guideline for prevention of retained surgical items" provides guidance for implementing a consistent, multidisciplinary approach to RSI prevention; accounting for surgical items; preventing retention of device fragments; reconciling count discrepancies; and using adjunct technologies to supplement manual count procedures. This article focuses on key points of the guideline to help perioperative personnel provide optimal care during a procedure. Key points addressed include taking responsibility for RSI prevention as a team; minimizing distractions, noise, and interruptions during counts; using consistent counting methods; reconciling discrepancies; and participating in performance-improvement activities. Perioperative RNs should review the complete guideline for additional information and for guidance in writing and updating policies and procedures. PMID:27350354

  20. Corrosion Preventive Compounds Lifetime Testing

    Science.gov (United States)

    Hale, Stephanie M.; Kammerer, Catherine C.; Copp, Tracy L.

    2007-01-01

    Lifetime Testing of Corrosion Preventive Compounds (CPCs) was performed to quantify performance in the various environments to which the Space Shuttle Orbiter is exposed during a flight cycle. Three CPCs are approved for use on the Orbiter: RD Calcium Grease, Dinitrol AV-30, and Braycote 601 EF. These CPCs have been rigorously tested to prove that they mitigate corrosion in typical environments, but little information is available on how they perform in the unique combination of the coastal environment at the launch pad, the vacuum of low-earth orbit, and the extreme heat of reentry. Currently, there is no lifetime or reapplication schedule established for these compounds that is based on this combination of environmental conditions. Aluminum 2024 coupons were coated with the three CPCs and exposed to conditions that simulate the environments to which the Orbiter is exposed. Uncoated Aluminum 2024 coupons were exposed to the environmental conditions as a control. Visual inspection and Electro- Impedance Spectroscopy (EIS) were performed on the samples in order to determine the effectiveness of the CPCs. The samples were processed through five mission life cycles or until the visual inspection revealed the initiation of corrosion and EIS indicated severe degradation of the coating.

  1. [Preventive vaccinations for medical personnel].

    Kerwat, Klaus; Goedecke, Marcel; Wulf, Hinnerk

    2014-05-01

    Vaccinations are among the most efficient and important preventive medical procedures. Modern vaccines are well tolerated. In Germany there are no longer laws for mandatory vaccinations, either for the general public or for medical personnel. Vaccinations are now merely "officially recommended" by the top health authorities on the basis of recommendations from the Standing Committee on Vaccinations (STIKO) of the Robert Koch Institute (RKI) according to § 20 para 3 of the Protection against Infection law (IfSG). The management of vaccine damage due to officially recommended vaccinations is guaranteed by the Federal States. Whereas vaccinations in childhood are generally considered to be a matter of course, the willingness to accept them decreases markedly with increasing age. In the medical sector vaccinations against, for example, hepatitis B are well accepted while other vaccinations against, for example, whooping cough or influenza are not considered to be so important. The fact that vaccinations, besides offering protection for the medical personnel, may also serve to protect the patients entrusted to medical care from nosocomial infections is often ignored.

  2. Injury prevention and public health

    Directory of Open Access Journals (Sweden)

    2010-06-01

    Full Text Available Injuries are one of the most under-recognized public health problems facing the world today. With more than 5 million deaths every year, violence and injuries account for 9% of global mortality, as many deaths as from HIV, Malaria and Tuberculosis combined. Eight of the 15 leading causes of death for people ages 15 to 29 years are injury-related: road traffic injuries, suicides, homicides, drowning, burns, war injuries, poisonings and falls. For every death due to war, there are three deaths due to homicide and five deaths due to suicide. However, most violence happens to people behind closed doors and results not in death, but often in years of physical and emotional suffering [1]. Injuries can be classified by intent: unintentional or intentional. Traffic injuries, fire-related injuries, falls, drowning, and poisonings are most often classified as unintentional injuries; injuries due to assault, selfinflicted violence such as suicide, and war are classified as intentional injuries, or violence. Worldwide, governments and public and private partners are increasingly aware of the strains that unintentional injuries and violence place on societies. In response they are strengthening data collection systems, improving services for victims and survivors, and increasing prevention efforts [1].

    2011-01-01

    The best means of preventing crime is to make it difficult to commit. As the summer holidays begin, in everybody’s interest we advise the following precautions: 1. MONEY, VALUABLES & KEYS Never leave money or objects of value unattended in offices or changing rooms, even locked. Keys and spares must always be taken away or kept in a safe place. Supposedly “safe” hiding places such as drawers, even locked, metal boxes and flower pots, are well known to burglars and should be avoided. Change lock codes regularly. 2. DOORS & WINDOWS Offices, workshops and meeting-rooms, etc. should be locked when vacated. Care should also be taken that windows are properly shut, especially if they are easily accessible from the outside. 3. VANDALISM If you witness an act of vandalism of public or private property, please report all the facts and your observations immediately to the CERN Fire Brigade (74444). 4.

  4. Prevention and Treatment of Drowning.

    Science.gov (United States)

    Mott, Timothy F; Latimer, Kelly M

    2016-04-01

    Nearly 4,000 drowning deaths occur annually in the United States, with drowning representing the most common injury-related cause of death in children one to four years of age. Drowning is a process that runs the spectrum from brief entry of liquid into the airways with subsequent clearance and only minor temporary injury, to the prolonged presence of fluid in the lungs leading to lung dysfunction, hypoxia, neurologic and cardiac abnormalities, and death. The World Health Organization has defined drowning as "the process of experiencing respiratory impairment from submersion/immersion in liquid." Terms such as near, wet, dry, passive, active, secondary, and silent drowning should no longer be used because they are confusing and hinder proper categorization and management. The American Heart Association's Revised Utstein Drowning Form and treatment guidelines are important in guiding care, disposition, and prognosis. Prompt resuscitation at the scene after a shorter duration of submersion is associated with better outcomes. Because cardiac arrhythmias due to drowning are almost exclusively caused by hypoxia, the resuscitation order prioritizes airway and breathing before compressions. Prevention remains the best treatment. Education, swimming and water safety lessons, and proper pool fencing are the interventions with the highest level of current evidence, especially in children two to four years of age. Alcohol use during water activities dramatically increases the risk of drowning; therefore, abstinence is recommended for all participants and supervisors. PMID:27035042

  5. Preventing dance injuries: current perspectives

    Science.gov (United States)

    Russell, Jeffrey A

    2013-01-01

    Dancers are clearly athletes in the degree to which sophisticated physical capacities are required to perform at a high level. The standard complement of athletic attributes – muscular strength and endurance, anaerobic and aerobic energy utilization, speed, agility, coordination, motor control, and psychological readiness – all are essential to dance performance. In dance, as in any athletic activity, injuries are prevalent. This paper presents the research background of dance injuries, characteristics that distinguish dance and dancers from traditional sports and athletes, and research-based perspectives into how dance injuries can be reduced or prevented, including the factors of physical training, nutrition and rest, flooring, dancing en pointe, and specialized health care access for dancers. The review concludes by offering five essential components for those involved with caring for dancers that, when properly applied, will assist them in decreasing the likelihood of dance-related injury and ensuring that dancers receive optimum attention from the health care profession: (1) screening; (2) physical training; (3) nutrition and rest; (4) specialized dance health care; and (5) becoming acquainted with the nature of dance and dancers.

  6. Preventive maintenance for mechanical components

    International Nuclear Information System (INIS)

    In nuclear power stations as in other industrial plants, there are active and passive components whose failure is permissible only in exceptional cases both from a safety and/or economic view. Failure in this context means loss of integrity of a supporting wall, insufficient function and/or unstoppable leakage. A systematic defect must be excluded as cause of failure; the consequences of failure must be manageable. During operation, measures must be taken to maintain the required quality and detect consequences of damage mechanisms at an early stage, prior to failure. This is achieved by preventive maintenance in accordance with the latest state of knowledge. To exclude systematic errors, the quality standard of components must be re-checked every once in a while as the effects of damage mechanisms and the state of knowledge are time-dependent parameters. This requires an integrated concept, e.g. for life and ageing management, in whose context a comprehensive knowledge base is developed and regularly updated. (orig.)

    Mayer, Cora A; Neilson, Amy A

    2010-03-01

    This article is the second in a series providing a summary of prevention strategies and vaccination for infections that may be acquired by travellers. The series aims to provide practical strategies to assist general practitioners in giving travel advice, as a synthesis of multiple information sources which must otherwise be consulted. Poliomyelitis is a potentially fatal viral illness, which may cause acute flaccid paralysis and permanent central nervous system damage. Ongoing global efforts to eradicate poliomyelitis have been under way since 1988. Travellers are at risk of infection in countries with endemic wild poliomyelitis virus or imported cases, and can spread the infection to areas where poliomyelitis has been eradicated. While all adults should be immune to poliomyelitis, it is important that at-risk travellers are vaccinated appropriately. Vaccine options and regions currently reporting poliomyelitis are presented from a number of sources, which may facilitate the process of giving travel advice in a general practice setting, although it is also important to seek up-to-date epidemiological information.

    Full Text Available Taking into account that climacteric constitutes a physiological state in woman’s life, which covers a large stage of her life cycle, it is important that nursery professionals will develop an Action Plan, whose main objective will be health. Covering, then, this stage from a multidisciplinary and holistic field is going to contribute to both: the adoption of healthy life habits and the repercussions that symptoms and physiological processes associated with menopause have on women. Another objective for nurses there must be to provide all our knowledge in a detailed and focused on the individual needs that may come up way. That way, we lay the foundations for facing climacteric with the minimum deterioration of the quality of life and well being.This article is an analysis of the etiology of every one of the most prevalent menopause problems, the predisposing factors to suffer them or to make them get worse, and the habits that are going to prevent larger spill-over effects of those problems. Furthermore, a revision about how nutrition, exercise, toxic substances consumption, etc. have repercussions on musculoskeletal problems, vascular symptoms, urogenital problems, psychological alterations, and gynaecological and breast cancer is made.

    Full Text Available Background: Robotic vehicles such as straddle carriers represent a popular form of cargo handling amongst container terminal operators.Objectives: The purpose of this industry-driven study is to model preventative maintenance (PM influences on the operational effectiveness of straddle carriers.Method: The study employs historical data consisting of 21 273 work orders covering a 27-month period. Two models are developed, both of which forecast influences of PM regimes for different types of carrier.Results: The findings of the study suggest that the reliability of the straddle fleet decreases with increased intervals of PM services. The study also finds that three factors – namely resources, number of new straddles, and the number of new lifting work centres – influence the performances of straddles.Conclusion: The authors argue that this collaborative research exercise makes a significant contribution to existing supply chain management literature, particularly in the area of operations efficiency. The study also serves as an avenue to enhance relevant management practice.

    Institute of Scientific and Technical Information of China (English)

    Young T.PARK; Jing SUN

    2009-01-01

    Most of the spare ordering policies treated up to now have assumed that preventive and corrective replacement costs are equal, which implies in essential that there is no significant need for preventive replacement. This paper presents an ordering policy for preventive age replacement with minimal repair. Introducing the replacement, repair, inventory holding and shortage costs, the expected cost rate is derived. A procedure to determine jointly the ordering time for a spare and the preventive replacement time for the operating unit so as to minimize the expected cost rate is proposed. To explain the ordering policy and the optimization procedure, a numerical example is also included.

  14. Workplace Bullying Prevention: A Critical Discourse Analysis

    JOHNSON, Susan L.

    2016-01-01

    Aim To analyze the discourses of workplace bullying prevention of hospital nursing unit managers and in the official documents of the organizations where they worked. Background Workplace bullying can be a self-perpetuating problem in nursing units. As such, efforts to prevent this behavior may be more effective than efforts to stop the behavior. There is limited research on how healthcare organizations characterize their efforts to prevent workplace bullying. Design This was a qualitative study. Method Critical discourse analysis and Foucault’s writings on governmentality and discipline were used to analyze data from interviews with hospital nursing unit managers (n=15) and organizational documents (n=22). Data were collected in 2012. Findings The discourse of workplace bullying prevention centered around three themes: prevention of workplace bullying through managerial presence, normalizing behaviors and controlling behaviors. All three are individual level discourses of workplace bullying prevention. Conclusion Current research indicates that workplace bullying is a complex issue with antecedents at the individual, departmental and organizational level. However, the discourse of the participants in this study only focused on prevention of bullying by moulding the behaviors of individuals. The effective prevention of workplace bullying will require departmental and organizational initiatives. Leaders in all types of organizations can use the results of this study to examine their organizations’ discourses of workplace bullying prevention to determine where change is needed. PMID:26010268

  1. Achieving monospermy or preventing polyspermy?

    Directory of Open Access Journals (Sweden)

    Dale B

    2016-06-01

    Full Text Available Brian Dale Centre for Assisted Fertilization, Naples, Italy Abstract: Images of sea urchin oocytes with hundreds of spermatozoa attached to their surface have fascinated scientists for over a century and led to the idea that oocytes have evolved mechanisms to allow the penetration of one spermatozoon while repelling supernumerary spermatozoa. Popular texts have extrapolated this concept, to the mammals and amphibians, and in many cases to include all the Phyla. Here, it is argued that laboratory experiments, using sea urchin oocytes deprived of their extracellular coats and inseminated at high densities, are artifactual and that the experiments leading to the idea of a fast block to polyspermy are flawed. Under natural conditions, the number of spermatozoa at the site of fertilization is extremely low, compared with the numbers generated. The sperm:oocyte ratio is regulated first by dilution in externally fertilizing species and the female reproductive tract in those with internal fertilization, followed by a bottleneck created by the oocytes extracellular coats. In order to progress to the oocyte plasma membrane, the fertilizing spermatozoon must encounter and respond to a correct sequence of signals from the oocytes extracellular coats. Those that do not, are halted in their progression by defective signaling and fall to the wayside. Final success and entry is finely tuned by the spermatozoon anchoring to an actin-rich predetermined site on the plasma membrane. In this review, the variation in the form, function, and number of gametes produced across the animal kingdom and the many ways in which sperm–oocyte interactions are regulated to reduce numbers are discussed. Since in nature, final sperm:oocyte ratios approach unity it would appear that selective pressures have favored the achievement of monospermy, rather than the evolution of polyspermy preventing mechanisms. Keywords: monospermy, natural conditions, polyspermy, laboratory

    Current child sexual abuse prevention programs assume that, by targeting potential victims, they can reduce the prevalence of child sexual abuse. This article presents findings that suggest this assumption is flawed. Suggests instead that potential offenders are more appropriate targets of prevention programs. (Contains 39 references.)

  19. Stroke Prevention: Managing Modifiable Risk Factors

    Directory of Open Access Journals (Sweden)

    Silvia Di Legge

    2012-01-01

    Full Text Available Prevention plays a crucial role in counteracting morbidity and mortality related to ischemic stroke. It has been estimated that 50% of stroke are preventable through control of modifiable risk factors and lifestyle changes. Antihypertensive treatment is recommended for both prevention of recurrent stroke and other vascular events. The use of antiplatelets and statins has been shown to reduce the risk of recurrent stroke and other vascular events. Angiotensin-converting enzyme inhibitors (ACEIs and angiotensin II receptor blockers (ARBs are indicated in stroke prevention because they also promote vascular health. Effective secondary-prevention strategies for selected patients include carotid revascularization for high-grade carotid stenosis and vitamin K antagonist treatment for atrial fibrillation. The results of recent clinical trials investigating new anticoagulants (factor Xa inhibitors and direct thrombin inhibitors clearly indicate alternative strategies in stroke prevention for patients with atrial fibrillation. This paper describes the current landscape and developments in stroke prevention with special reference to medical treatment in secondary prevention of ischemic stroke.

  14. Translating research to practice in bullying prevention.

    Science.gov (United States)

    Bradshaw, Catherine P

    2015-01-01

    Bullying continues to be a concern in schools and communities across the United States and worldwide, yet there is uncertainty regarding the most effective approaches for preventing it and addressing its impacts on children and youth. This paper synthesizes findings from a series of studies and meta-analyses examining the efficacy of bullying prevention programs. This paper considers some methodological issues encountered when testing the efficacy and effectiveness of bullying prevention and intervention approaches. It also identifies several areas requiring additional research in order to increase the effectiveness of bullying prevention efforts in real-world settings. Drawing upon a public health perspective and findings from the field of prevention science, this paper aims to inform potential future directions for enhancing the adoption, high quality implementation, and dissemination of evidence-based bullying prevention programs. It is concluded that although bullying prevention programs can be effective in reducing bullying and victimization among school-aged youth, there is a great need for more work to increase the acceptability, fidelity, and sustainability of the existing programs in order to improve bullying-related outcomes for youth. The findings from this review are intended to inform both policy and public health practice related to bullying prevention. PMID:25961313

    Science.gov (United States)

    Martínez González, C; Riaño Galán, I; Sánchez Jacob, M; González de Dios, J

    2014-12-01

    The growing capacity of medicine to generate more iatrogenic events than ever, and the risk of unsustainability of health systems have led to new prevention concept: quaternary prevention aimed at restraining medicalization. Quaternary prevention is essential in the phenomenon called disease mongering, which could be translated as commercialization of disease. Encouraging this sort of prevention and halting the consequences of disease mongering requires the development of all the institutional potential for prevention, as well as all the personal willingness for restraint; it involves separating us from the unnecessary auspices of industry, being critical of our work, not being maleficent, respecting the principle of justice as managers of the limited public resources and making ourselves feel responsible for the social cost resulting from medical decisions. From this point of view, this work analyses neonatal screening, developments in the area of neonatology and primary health care.

  4. Probiotics in the prevention of dental caries

    Directory of Open Access Journals (Sweden)

    Johany Duque de Estrada Riverón

    2010-11-01

    Full Text Available Probiotics have the potential to provide significant benefits to human health, so we decided to investigate the probiotics species that may have preventive action against dental caries mainly in children in order to determine if there can be created a preventive medicine, made from probiotics found in the oral cavity. Oral probiotics that have shown promising activities in the prevention of dental caries are: Streptococcus salivarius (strain K12, BGH01 Lactobacillus salivarius, BGH089 gasseri Lactobacillus, Streptococcus sanguinis and Streptococcus oligofermentans. In vitro studies on the use of probiotics for the prevention of dental caries have shown interesting results, but in vivo they are not very encouraging. It is necessary to deepen in the therapeutic effects of probiotics strains already discovered in order to obtain from them an effective preventive agent against dental caries and so ensuring a better quality of life, especially in children.

  6. Prevention of crib-biting: a review.

    Science.gov (United States)

    McGreevy, P D; Nicol, C J

    1998-11-01

    Crib-biting is a common oral stereotype. Because of perceived deleterious effects on the health and appearance of subjects the prevention of crib-biting is regularly attempted. The resourcefulness of horses in satisfying their motivation to perform this behaviour often frustrates owners' efforts at prevention. This paper reviews the efficacy and observable consequences of attempting to prevent crib-biting by a variety of methods. These include attempts to prevent the grasping of objects, to interfere with air-engulfing and to introduce punishment for grasping and neck-flexion. Other approaches include the use of surgery, acupuncture, pharmaceuticals, operant feeding and environmental enrichment. A remedy that is effective for every crib-biter remains elusive. We conclude that, rather than concentrating on remedial prevention, further research should be directed at establishing why horses crib-bite and how the emergence of crib-biting can be avoided.

    curves allow to identify children who have a real risk of developing obesity. (2) By the age of 6 years, when due to normal physiological variations, clinical assessment can be misleading. The BMI curves allow to identify children at risk. When a child is identified as having a real risk of obesity, simple preventive measures, adapted for each subject, could avoid a development toward massive obesity, which may become difficult to reduce if managed too late.

    2012-09-01

    Groundwater contamination prevention mapping is an important component of groundwater contamination geological survey and assessment work, which could provide the basis for making and implementing groundwater contamination prevention planning. A groundwater contamination prevention mapping system was constructed in view of the synthetic consideration on nature perspective derived from groundwater contamination sources and aquifer itself, social-economic perspective, policy perspective derived from outside. During the system construction process, analytic hierarchy process and relevant overlaying principles were used to couple groundwater contamination risk assessment, groundwater value as well as wellhead protection area zoning. Data processing and visualization of mapping results were achieved in the GIS environment. The research on groundwater contamination prevention mapping in Beijing Plain indicated that the final groundwater prevention map was in accordance with the actual conditions and well reflected the priorities of groundwater prevention, which could play a guidance role in designing and implementing further practical prevention and supervision measures. Besides, because of the dynamical properties of the system components, it was suggested to analyze the update frequency of the mapping. PMID:23243867

  14. Strategies for the prevention of unsafe abortion.

    Science.gov (United States)

    Faúndes, Anibal

    2012-10-01

    Unsafe abortion is one of the main causes of maternal mortality and severe morbidity in countries with restrictive abortion laws. In 2007, the International Federation of Gynecology and Obstetrics (FIGO) created a Working Group on the Prevention of Unsafe Abortion and its Consequences (WGPUA). This led to a FIGO initiative with that aim which has the active participation of 43 FIGO member societies. The WGPUA has recommended that the plans of action of the countries participating in the initiative consider several levels of prevention shown to have the potential to successfully reduce unsafe abortions: (1) primary prevention of unintended pregnancy and induced abortion; (2) secondary prevention to ensure the safety of an abortion procedure that could not be avoided; (3) tertiary prevention of further complications of an unsafe abortion procedure that has taken place already, through high-quality postabortion care; and (4) quaternary prevention of repeated abortion procedures through postabortion family planning counseling and contraceptive services. This paper reviews these levels of prevention and the evidence that they can be effective.

    2011-12-01

    The limited success of youth violence prevention interventions suggests that effective prevention needs to address causes at multiple levels of analysis and empower youth in developing and implementing prevention programs. In this article, we review published studies of youth violence prevention efforts that engage youth in developing or implementing violence prevention activities. The reviewed studies suggest the promise of youth empowerment strategies and the need for systematic outcome studies of empowerment programs. After reviewing empowerment theory applied to youth violence prevention programs, we present a case study of the Youth Empowerment Solutions (YES) for Peaceful Communities program. YES engages middle-school youth in an after-school and summer program that includes a culturally tailored character development curriculum and empowers the youth to plan and implement community improvement projects with assistance from adult neighborhood advocates. The case study focuses on outcome evaluation results and presents evidence of the YES program effects on community-level outcomes (eg, property improvements, violent crime incidents) and on individual-level outcomes (eg, conflict avoidance, victimization). The literature review and the case study suggest the promise of engaging and empowering youth to plan and implement youth violence prevention programs.

    Feigin, Valery L; Norrving, Bo; George, Mary G; Foltz, Jennifer L; Roth, Gregory A; Mensah, George A

    2016-09-01

    The increasing global stroke burden strongly suggests that currently implemented primary stroke prevention strategies are not sufficiently effective, and new primary prevention strategies with larger effect sizes are needed. Here, we review the latest stroke epidemiology literature, with an emphasis on the recently published Global Burden of Disease 2013 Study estimates; highlight the problems with current primary stroke and cardiovascular disease (CVD) prevention strategies; and outline new developments in primary stroke and CVD prevention. We also suggest key priorities for the future, including comprehensive prevention strategies that target people at all levels of CVD risk; implementation of an integrated approach to promote healthy behaviours and reduce health disparities; capitalizing on information technology to advance prevention approaches and techniques; and incorporation of culturally appropriate education about healthy lifestyles into standard education curricula early in life. Given the already immense and fast-increasing burden of stroke and other major noncommunicable diseases (NCDs), which threatens worldwide sustainability, governments of all countries should develop and implement an emergency action plan addressing the primary prevention of NCDs, possibly including taxation strategies to tackle unhealthy behaviours that increase the risk of stroke and other NCDs.

    2016-01-01

    We aim to review the literature and provide guidance on preventive health measures in inflammatory bowel disease (IBD). Structured searches were performed in PubMed, MEDLINE, EMBASE, Web of Science and Cochrane Library from January 1976 to June 2016 using the following keywords: (inflammatory bowel disease OR Crohn’s disease OR ulcerative colitis) AND (health maintenance OR preventive health OR health promotion). Abstracts of the articles selected from each of these multiple searches were reviewed, and those meeting the inclusion criteria (that is, providing data regarding preventive health or health maintenance in IBD patients) were recorded. Reference lists from the selected articles were manually reviewed to identify further relevant studies. Patients with IBD are at increased risk of developing adverse events related to the disease course, therapeutic interventions, or non-adherence to medication. Recent studies have suggested that IBD patients do not receive preventive services with the same thoroughness as patients with other chronic diseases. Preventive health measures can avert morbidity and improve the quality of life of patients with IBD. Gastroenterologists and primary care physicians (PCPs) should have an up to date working knowledge of preventive health measures for IBD patients. A holistic approach and better communication between gastroenterologists and PCPs with explicit clarification of roles will prevent duplication of services and streamline care. PMID:27678347

  18. Optimization of preventive health care facility locations

    Directory of Open Access Journals (Sweden)

    McGregor S

    2010-03-01

    Full Text Available Abstract Background Preventive health care programs can save lives and contribute to a better quality of life by diagnosing serious medical conditions early. The Preventive Health Care Facility Location (PHCFL problem is to identify optimal locations for preventive health care facilities so as to maximize participation. When identifying locations for preventive health care facilities, we need to consider the characteristics of the preventive health care services. First, people should have more flexibility to select service locations. Second, each preventive health care facility needs to have a minimum number of clients in order to retain accreditation. Results This paper presents a new methodology for solving the PHCFL problem. In order to capture the characteristics of preventive health care services, we define a new accessibility measurement that combines the two-step floating catchment area method, distance factor, and the Huff-based competitive model. We assume that the accessibility of preventive health care services is a major determinant for participation in the service. Based on the new accessibility measurement, the PHCFL problem is formalized as a bi-objective model based on efficiency and coverage. The bi-objective model is solved using the Interchange algorithm. In order to accelerate the solving process, we implement the Interchange algorithm by building two new data structures, which captures the spatial structure of the PHCFL problem. In addition, in order to measure the spatial barrier between clients and preventive health care facilities accurately and dynamically, this paper estimates travelling distance and travelling time by calling the Google Maps Application Programming Interface (API. Conclusions Experiments based on a real application for the Alberta breast cancer screening program show that our work can increase the accessibility of breast cancer screening services in the province.

    Full Text Available Hyperglycemia promotes oxidative stress and hence generation of reactive oxygen species (ROS, which is known to play a crucial role in the pathogenesis of diabetic nephropathy. Metformin, an oral hypoglycemic drug, possesses antioxidant effects. The aim of this paper is to investigate the protective effects of metformin on the injury of renal podocytes in spontaneously diabetic Torii (SDT rats, a new model for nonobese type 2 diabetes. Metformin (350 mg/kg/day was given to SDT rats for 17 weeks. Blood glucose, glycated haemoglobin (HbA1c, and albuminuria were examined. Kidney histopathology, renal 8-hydroxydeoxyguanosine (8-OHdG levels and apoptosis were examined. In 43-week-old SDT rats, severe hyperglycemia was developed, and albuminuria was markedly increased. Diabetes induced significant alterations in renal glomerular structure. In addition, urinary and renal 8-OHdG levels were highly increased, and podocyte loss was shown through application of the TUNEL and synaptopodin staining. However, treatment of SDT rats with metformin restored all these renal changes. Our data suggested that diabetes-induced podocyte loss in diabetic nephropathy could be suppressed by the antidiabetes drug, metformin, through the repression of oxidative injury.

    This study examined the use of preventive health services among Korean American adults. Data were drawn from a cross-sectional survey of 212 Korean Americans in the Chicago, Illinois, metropolitan area. Guided by the Andersen's behavioral model, the authors examined whether predisposing (age, gender, marital status, household size, education), enabling (income, health insurance, English proficiency, citizenship, social network), and need (health status) factors are predictive of Korean Americans' preventive health services utilization. A binomial logistic regression showed that younger age, male, noncitizen, low income, no insurance, a larger family network, and better perceived health were associated with decreased odds of using preventive health services.
