    The 3'-azido-2',3'-dideoxy-β-ribosylthymine (AZT, Zidovudine) is a cytostatic antivirial drug worldwide used in AIDS treatment or, in combination with other antiproliferative drugs, in treatment of cancer. About 30-40% of AZT is metabolised by conjunction with glucuronic acid in liver and about 70% is eliminated untouched by urinary system. In this work a possible fate of the AZT in the environment is studied. To this end, a product of AZT biotransformation by an environmental strain, Stenotrophomonas maltophilia, (aerobic, Gram(-) rod, common in soil and water) is found and isolated by HPLC and TLC techniques and identified by NMR and mass spectroscopy. All the molecular spectroscopy methods confirm presence of the product, which is AZT molecule hydroxylated in the position 2' of the deoxyribose ring.

    The Cu(I) catalyzed Huisgen 1,3-dipolar azide-alkyne cycloaddition (CuAAC) was applied for a nucleoside-peptide bioconjugation. Systemin (Sys), an 18-aa plant signaling peptide naturally produced in response to wounding or pathogen attack, was chemically synthesized as its N-propynoic acid functionalized analog (Prp-Sys) using the SPPS. Next, CuAAC was applied to conjugate Prp-Sys with 3'-azido-2',3'-dideoxythymidine (AZT), a model cargo molecule. 1,4-Linked 1,2,3-triazole AZT-Sys conjugate was designed to characterize the spreading properties and ability to translocate of cargo molecules of systemin. CuAAC allowed the synthesis of the conjugate in a chemoselective and regioselective manner, with high purity and yield. The presence of Cu(I) ions generated in situ drove the CuAAC reaction to completion within a few minutes without any by-products. Under typical separation conditions of phosphate 'buffer' at low pH and uncoated fused bare-silica capillary, an increasing peak intensity assigned to triazole-linked AZT-Sys conjugate was observed using capillary electrophoresis (CE) during CuAAC. CE analysis showed that systemin peptides are stable in tomato leaf extract for up to a few hours. CE-ESI-MS revealed that the native Sys and its conjugate with AZT are translocated through the tomato stem and can be directly detected in stem exudates. The results show potential application of systemin as a transporter of low molecular weight cargo molecules in tomato plant and of CE method to characterize a behavior of plant peptides and its analogs.

    Full Text Available Maternal-fetal HIV-1 transmission can be prevented by administration of AZT, alone or in combination with other antiretroviral drugs to pregnant HIV-1-infected women and their newborns. In spite of the benefits deriving from this life-saving prophylactic therapy, there is still considerable uncertainty on the potential long-term adverse effects of antiretroviral drugs on exposed children. Clinical and experimental studies have consistently shown the occurrence of mitochondrial dysfunction and increased oxidative stress following prenatal treatment with antiretroviral drugs, and clinical evidence suggests that the developing brain is one of the targets of the toxic action of these compounds possibly resulting in behavioral problems. We intended to verify the effects on brain and behavior of mice exposed during gestation to AZT, the backbone of antiretroviral therapy during human pregnancy. We hypothesized that glutamate, a neurotransmitter involved in excitotoxicity and behavioral plasticity, could be one of the major actors in AZT-induced neurochemical and behavioral alterations. We also assessed the antioxidant and neuroprotective effect of L-acetylcarnitine, a compound that improves mitochondrial function and is successfully used to treat antiretroviral-induced polyneuropathy in HIV-1 patients. We found that transplacental exposure to AZT given per os to pregnant mice from day 10 of pregnancy to delivery impaired in the adult offspring spatial learning and memory, enhanced corticosterone release in response to acute stress, increased brain oxidative stress also at birth and markedly reduced expression of mGluR1 and mGluR5 subtypes and GluR1 subunit of AMPA receptors in the hippocampus. Notably, administration during the entire pregnancy of L-acetylcarnitine was effective in preventing/ameliorating the neurochemical, neuroendocrine and behavioral adverse effects induced by AZT in the offspring. The present preclinical findings provide a

    The pharmacokinetics, metabolism, and toxicity of Zidampidine, an aryl phosphate derivative of AZT, 3'-azidothymidine-5'-[p-bromophenyl methoxyalaninyl phosphate] were investigated in CD-1 mice. Following iv injection, Zidampidine was rapidly converted to its metabolites Ala-AZT-MP and AZT. Zidampidine was not toxic to mice at doses up to 250mg/kg. We next examined the therapeutic effect of Zidampidine in CBA mice challenged with intracerebral injections of the Josiah strain of Lassa virus. Mice were treated either with vehicle or non-toxic doses of Zidampidine administered intraperitoneally 24h prior, 1h prior, and 24, 48, 72, and 96h after virus inoculation. The probability of survival following the Lassa challenge was significantly improved for Zidampidine-treated mice (Kaplan Meier, Log-Rank p value<0.0001). This pilot study provides the basis for future preclinical evaluation of Zidampidine and its potential as a new agent for the treatment of viral hemorrhagic fevers caused by Lassa virus.

    Human immunodeficiency virus (HIV-1) develops resistance to 3'-azido-2',3'-deoxythymidine (AZT, zidovudine) by acquiring mutations in reverse transcriptase that enhance the ATP-mediated excision of AZT monophosphate from the 3' end of the primer. The excision reaction occurs at the dNTP-binding site, uses ATP as a pyrophosphate donor, unblocks the primer terminus and allows reverse transcriptase to continue viral DNA synthesis. The excision product is AZT adenosine dinucleoside tetraphosphate (AZTppppA). We determined five crystal structures: wild-type reverse transcriptase-double-stranded DNA (RT-dsDNA)-AZTppppA; AZT-resistant (AZTr; M41L D67N K70R T215Y K219Q) RT-dsDNA-AZTppppA; AZTr RT-dsDNA terminated with AZT at dNTP- and primer-binding sites; and AZTr apo reverse transcriptase. The AMP part of AZTppppA bound differently to wild-type and AZTr reverse transcriptases, whereas the AZT triphosphate part bound the two enzymes similarly. Thus, the resistance mutations create a high-affinity ATP-binding site. The structure of the site provides an opportunity to design inhibitors of AZT-monophosphate excision.

    Seven nucleoside reverse transcriptase (RT) inhibitors are currently used in the clinical treatment of acquired immunodeficiency syndrome (AIDS). These substrate analogues block DNA synthesis by the viral enzyme RT. However, the emergence of resistant variants of RT allied to their long-term toxicity requires the design of new and better RT inhibitors, with long-term in vivo efficacy. In this work we used density functional theory (DFT) calculations to develop a set of molecular mechanics (MM) parameters committed to the AMBER force field for one of the most used in the clinic nucleoside reverse transcriptase inhibitors (NRTIs): zidovudine (AZT). These parameters were tested by comparing the optimized geometries of AZT at both the DFT and MM levels of theory. The ability of the new parameters to reproduce the torsional energy of the azide group was also verified by scanning the surface in MM with the new parameters and comparing the results with the same potential energy surface (PES) at the DFT level. Finally, the parameters were validated through classical MD simulations of AZT in aqueous environment.

    Full Text Available A hallmark of tumor cell survival is the maintenance of elongated telomeres. It is known that antiviral reverse transcriptase inhibitors (RTIs such as azidothymidine (AZT and didanosine (ddI lead to telomere shortening at high, potentially toxic concentrations. We hypothesized that those drugs might have synergistic effects enabling successful therapy with low, nontoxic concentrations. Biologic effects of AZT and ddI were analyzed at concentrations that correspond to minimal plasma levels achieved during human immunodeficiency virus therapy. Long-term coapplication of low-dose AZT and ddI induced a significant shortening of telomeres in the tumor cell lines HCT-116, SkMel-28, MelJuso, and Jurkat. Treatment of cells with both RTI, but not with single RTI, led to a significant accumulation of γH2AX, to p53 phosphorylation, and to cell apoptosis in all cell lines. Oral low-dose dual RTI application but not low-dose single RTI application was associated with a significantly reduced tumor growth of HCT-116 cells in mice. This antiproliferative activity of the combined use of AZT and ddI at low, clinically applicable concentrations warrants clinical testing in human solid cancer.

  12. 3'-Azido-3'-deoxythymidine (AZT) induces apoptosis and alters metabolic enzyme activity in human placenta

    International Nuclear Information System (INIS)

    The anti-HIV drug 3'-azido-3'-deoxythymidine (AZT) is the drug of choice for preventing maternal-fetal HIV transmission during pregnancy. Our aim was to assess the cytotoxic effects of AZT on human placenta in vitro. The mechanisms of AZT-induced effects were investigated using JEG-3 choriocarcinoma cells and primary explant cultures from term and first-trimester human placentas. Cytotoxicity measures included trypan blue exclusion, MTT, and reactive oxygen species (ROS) assays. Apoptosis was measured with an antibody specific to cleaved caspase-3 and by rescue of cells by the general caspase inhibitor Boc-D-FMK. The effect of AZT on the activities of glutathione-S-transferase, β-glucuronidase, UDP-glucuronosyl transferase, cytochrome P450 (CYP) 1A, and CYP reductase (CYPR) in the placenta was assessed using biochemical assays and immunoblotting. AZT increased ROS levels, decreased cellular proliferation rates, was toxic to mitochondria, and initiated cell death by a caspase-dependent mechanism in the human placenta in vitro. In the absence of serum, the effects of AZT were amplified in all the models used. AZT also increased the amounts of activity of GST, β-glucuronidase, and CYP1A, whereas UGT and CYPR were decreased. We conclude that AZT causes apoptosis in the placenta and alters metabolizing enzymes in human placental cells. These findings have implications for the safe administration of AZT in pregnancy with respect to the maintenance of integrity of the maternal-fetal barrier

    Full Text Available Abstract In this study we report the effect of AZT on the whole protein expression profile both in the control and the AZT-treated K562 cells, evidenced by two-dimensional gel electrophoresis and peptide mass fingerprinting analysis. Two-dimensional gels computer digital image analysis showed two spots that appeared up-regulated in AZT-treated cells and one spot present only in the drug exposed samples. Upon extraction and analysis by peptide mass fingerprinting, the first two spots were identified as PDI-A3 and stathmin, while the third one was proved to be NDPK-A. Conversely, two protein spots were present only in the untreated K562 cells, and were identified as SOD1 and HSP-60, respectively.

  14. Why do HIV-1 and HIV-2 use different pathways to develop AZT resistance?

    Directory of Open Access Journals (Sweden)

    2006-02-01

    Full Text Available The human immunodeficiency virus type 1 (HIV-1 develops resistance to all available drugs, including the nucleoside analog reverse transcriptase inhibitors (NRTIs such as AZT. ATP-mediated excision underlies the most common form of HIV-1 resistance to AZT. However, clinical data suggest that when HIV-2 is challenged with AZT, it usually accumulates resistance mutations that cause AZT resistance by reduced incorporation of AZTTP rather than selective excision of AZTMP. We compared the properties of HIV-1 and HIV-2 reverse transcriptase (RT in vitro. Although both RTs have similar levels of polymerase activity, HIV-1 RT more readily incorporates, and is more susceptible to, inhibition by AZTTP than is HIV-2 RT. Differences in the region around the polymerase active site could explain why HIV-2 RT incorporates AZTTP less efficiently than HIV-1 RT. HIV-1 RT is markedly more efficient at carrying out the excision reaction with ATP as the pyrophosphate donor than is HIV-2 RT. This suggests that HIV-1 RT has a better nascent ATP binding site than HIV-2 RT, making it easier for HIV-1 RT to develop a more effective ATP binding site by mutation. A comparison of HIV-1 and HIV-2 RT shows that there are numerous differences in the putative ATP binding sites that could explain why HIV-1 RT binds ATP more effectively. HIV-1 RT incorporates AZTTP more efficiently than does HIV-2 RT. However, HIV-1 RT is more efficient at ATP-mediated excision of AZTMP than is HIV-2 RT. Mutations in HIV-1 RT conferring AZT resistance tend to increase the efficiency of the ATP-mediated excision pathway, while mutations in HIV-2 RT conferring AZT resistance tend to increase the level of AZTTP exclusion from the polymerase active site. Thus, each RT usually chooses the pathway best suited to extend the properties of the respective wild-type enzymes.

    Full Text Available The determination of chemical purity, melting range, and variation of enthalpy in the process of characterizing medicines is one of the principal requirements evaluated in quality control of the pharmaceutical industry. In this study, the method of purity determination using DSC was outlined, as well as the application of this technique for the evaluation of commercial samples of zidovudine (AZT (raw material supplied by different laboratories. To this end, samples from six different laboratories (A, B, C, D, E, and F and the standard reference (R from the United States Pharmacopeia (USP were analyzed. The DSC curves were obtained in the temperature range of 25 to 200 ºC under the dynamic atmosphere of N2 (50 mL min-1, heating rate of β=2 ºC min-1, using an Al capsule containing approximately 2 mg of sample material. The results demonstrated that the standard reference presented a proportion of 99.83% whereas the AZT samples presented a variation ranging from 97.59 to 99.54%. In addition, the standard reference was found to present a temperature of onset of melting point of 122.80 °C. Regarding the samples of active agents provided by the different laboratories, a variation ranging from 118.70 to 122.87 °C was measured.

    Judith Ziske

    Full Text Available INTRODUCTION: Tanzanian guidelines for prevention of mother-to-child-transmission of HIV (PMTCT recommend an antiretroviral combination regimen involving zidovudine (AZT during pregnancy, single-dosed nevirapine at labor onset, AZT plus Lamivudine (3TC during delivery, and AZT/3TC for 1-4 weeks postpartum. As drug toxicities are a relevant concern, we assessed hematological alterations in AZT-exposed women and their infants. METHODS AND MATERIALS: A cohort of HIV-positive women, either with AZT intake (n = 82, group 1 or without AZT intake (n = 62, group 2 for PMTCT during pregnancy, was established at Kyela District Hospital, Tanzania. The cohort also included the infants of group 1 with an in-utero AZT exposure ≥4 weeks, receiving AZT for 1 week postpartum (n = 41, and infants of group 2 without in-utero AZT exposure, receiving a prolonged 4-week AZT tail (n = 58. Complete blood counts were evaluated during pregnancy, birth, weeks 4-6 and 12. RESULTS: For women of group 1 with antenatal AZT intake, we found a statistically significant decrease in hemoglobin level, red blood cells, white blood cells, granulocytes, as well as an increase in red cell distribution width and platelet count. At delivery, the median red blood cell count was significantly lower and the median platelet count was significantly higher in women of group 1 compared to group 2. At birth, infants from group 1 showed a lower median hemoglobin level and granulocyte count and a higher frequency of anemia and granulocytopenia. At 4-6 weeks postpartum, the mean neutrophil granulocyte count was significantly lower and neutropenia was significantly more frequent in infants of group 2. CONCLUSIONS: AZT exposure during pregnancy as well as after birth resulted in significant hematological alterations for women and their newborns, although these changes were mostly mild and transient in nature. Research involving larger cohorts is needed to further analyze the impact

  18. Azithromycin treatment alters gene expression in inflammatory, lipid metabolism, and cell cycle pathways in well-differentiated human airway epithelia.

    Carla Maria P Ribeiro

    Full Text Available Prolonged macrolide antibiotic therapy at low doses improves clinical outcome in patients affected with diffuse panbronchiolitis and cystic fibrosis. Consensus is building that the therapeutic effects are due to anti-inflammatory, rather than anti-microbial activities, but the mode of action is likely complex. To gain insights into how the macrolide azithromycin (AZT modulates inflammatory responses in airways, well-differentiated primary cultures of human airway epithelia were exposed to AZT alone, an inflammatory stimulus consisting of soluble factors from cystic fibrosis airways, or AZT followed by the inflammatory stimulus. RNA microarrays were conducted to identify global and specific gene expression changes. Analysis of gene expression changes revealed that the AZT treatment alone altered the gene profile of the cells, primarily by significantly increasing the expression of lipid/cholesterol genes and decreasing the expression of cell cycle/mitosis genes. The increase in cholesterol biosynthetic genes was confirmed by increased filipin staining, an index of free cholesterol, after AZT treatment. AZT also affected genes with inflammatory annotations, but the effect was variable (both up- and down-regulation and gene specific. AZT pretreatment prevented the up-regulation of some genes, such as MUC5AC and MMP9, triggered by the inflammatory stimulus, but the up-regulation of other inflammatory genes, e.g., cytokines and chemokines, such as interleukin-8, was not affected. On the other hand, HLA genes were increased by AZT. Notably, secreted IL-8 protein levels did not reflect mRNA levels, and were, in fact, higher after AZT pretreatment in cultures exposed to the inflammatory stimulus, suggesting that AZT can affect inflammatory pathways other than by altering gene expression. These findings suggest that the specific effects of AZT on inflamed and non-inflamed airway epithelia are likely relevant to its clinical activity, and their apparent

    In developing their Site Treatment Plans (STPs), many of the Department of Energy installations identified some form of portable treatment, to facilitate compliant disposition of select mixed low-level wastestreams. The Environmental Management Office of Science and Technology requested that a systems study be performed to better define the potential role of portable treatment with respect to mixed low-level waste, highlight obstacles to implementation, and identify opportunities for future research and development emphasis. The study was performed by first establishing a representative set of mixed waste, then formulating portable treatment system concepts to meet the required processing needs for these wastes. The portable systems that were conceptualized were evaluated and compared to a fixed centralized treatment alternative. The system evaluations include a life-cycle cost analysis and an assessment of regulatory, institutional, and technical issues associated with the potential use of portable systems. The results of this study show that when all costs are included, there are no significant cost differences between portable systems and fixed systems. However, it is also emphasized that many uncertainties exist that could impact the cost of implementing portable treatment systems. Portable treatment could be made more attractive through private sector implementation, although there is little economic incentive for a commercial vendor to develop small, specialized treatment capabilities with limited applicability. Alternatively, there may also be valid reasons why fixed units cannot be used for some problematic wastestreams. In any event, there are some site-specific problems that still need to be addressed, and there may be some opportunity for research and development to make a positive impact in these areas.

    Background An zidovudine (AZT)-substitution regimen containing 24-week stavudine (d4T) followed by long-term AZT for HIV therapy is potential to trade off short-term AZT-related anemia and long-term risks associated with d4T in resourcelimited settings.However,evidence is scarce.This study aims to assess the efficacy and safety of AZT-substitution regimen,aiming to find a regimen with better efficacy,less adverse events,and more affordability in resource-limited settings.Methods This prospective,multicenter study enrolled 499 (190 on d4T regimen,172 on AZT regimen,and 137 on AZT-substitution regimen) HIV-1-infected subjects who initiated combined antiretroviral therapy and attended follow-up visits over 96 weeks from 2009 to 2011.Lamivudine (3TC) and either nevirapine (NVP) or efavirenz (EFV) were the other two drugs in the antiretroviral regimens.Virologic and immunologic responses and adverse events were monitored at baseline and at weeks 4,12,24,36,48,60,72,84,and 96.Results In terms of hematological adverse effects,AZT-substitution group had similar safety profiles to d4T group and was superior to AZT group.In comparison with AZT-substitution group,AZT group was associated with higher risk of developing anemia (adjusted hazard ratio (aHR)for anemia ≥ grade Ⅱ,8.44,95% CI 1.81-39.46) and neutropenia (aHR for neutropenia ≥ grade Ⅱ,1.86,95% CI 1.19-2.93).The prevalence of lipodystrophy in d4T group was 19.5%,while that in AZT-substitution group was zero.As to antiretroviral efficacy,these three groups showed no differences.Conclusion AZT-substitution regimen provides a relatively safe and effective first-line antiretroviral strategy in resource-limited settings.

    Full Text Available The aim of this work was to compare the performances of the L'vov and integrated platforms in order to overcome the interferences found on lead determination in zidovudine by ET AAS. Pyrolysis and atomization temperatures found with integrated platform were 700 and 1400°C, respectively. The characteristic masses were 12.7 ± 1.2 pg with integrated platform and 11.1 ± 1.3 pg with grooved platform. The ratio between the slopes of zidovudine and aqueous curves shows a decrease in the interferences when the L'vov platform is used (bAZT/b aq = 0.97 ± 0.10 and the detection limit found was 0.03 µg.g-1. That ratio was 0.85 ± 0.07 with the integrated platform.

    Abstract To test whether a thymidine analog zidovudine (=AZT), is able to modify the radiosensitizing effects of (E)-2'-Deoxy-(fluoromethylene)cytidine (FMdC). A human colon cancer cell line Widr was exposed for 48 hours prior to irradiation to FMdC. Zidovudine was added at various concentrations immediately before irradiation. We measured cell survival and the effect of FMdC, AZT and FMdC + AZT on deoxynucleotide triphosphate pool. FMdC results in a significant increase of radiosensitivit...

  4. The engineered thymidylate kinase (TMPK/AZT enzyme-prodrug axis offers efficient bystander cell killing for suicide gene therapy of cancer.

    Directory of Open Access Journals (Sweden)

    Full Text Available We previously described a novel suicide (or 'cell fate control' gene therapy enzyme/prodrug system based on an engineered variant of human thymidylate kinase (TMPK that potentiates azidothymidine (AZT activation. Delivery of a suicide gene sequence into tumors by lentiviral transduction embodies a cancer gene therapy that could employ bystander cell killing as a mechanism driving significant tumor regression in vivo. Here we present evidence of a significant bystander cell killing in vitro and in vivo mediated by the TMPK/AZT suicide gene axis that is reliant on the formation of functional gap-junctional intercellular communications (GJICs. Potentiation of AZT activation by the engineered TMPK expressed in the human prostate cancer cell line, PC-3, resulted in effective bystander killing of PC-3 cells lacking TMPK expression--an effect that could be blocked by the GJIC inhibitor, carbenoxolone. Although GJICs are mainly formed by connexins, a new family of GJIC molecules designated pannexins has been recently identified. PC-3 cells expressed both connexin43 (Cx43 and Pannexin1 (Panx1, but Panx1 expression predominated at the plasma membrane, whereas Cx43 expression was primarily localized to the cytosol. The contribution of bystander effects to the reduction of solid tumor xenografts established by the PC-3 cell line was evaluated in an animal model. We demonstrate the contribution of bystander cell killing to tumor regression in a xenograft model relying on the delivery of expression of the TMPK suicide gene into tumors via direct intratumoral injection of recombinant therapeutic lentivirus. Taken together, our data underscore that the TMPK/AZT enzyme-prodrug axis can be effectively utilized in suicide gene therapy of solid tumors, wherein significant tumor regression can be achieved via bystander effects mediated by GJICs.

  6. Sludge treatment studies

    International Nuclear Information System (INIS)

    Solid formation in filtered leachates and wash solutions was seen in five of the six sludges treated by Enhanced Sludge Washing. Solid formation in process solutions takes a variety of forms: very fine particles, larger particulate solids, solids floating in solution like egg whites, gels, crystals, and coatings on sample containers. A gel-like material that formed in a filtered leachate from Enhanced Sludge Washing of Hanford T-104 sludge was identified as natrophosphate, Na7(PO4)2F·19H2O. A particulate material that formed in a filtered caustic leachate from Hanford SX-113 sludge contained sodium and silicon. This could be any of a host of sodium silicates in the NaOH-SiO2-H2O system. Acidic treatment of Hanford B-202 sludge with 1 M, 3 M, and 6 M HNO3 sequential leaching resulted in complete dissolution at 75 C, but not at ambient temperature. This treatment resulted in the formation of solids in filtered leachates. Analyses of the solids revealed that a gel material contained silica with some potassium, calcium, iron, and manganese. Two phases were embedded in the gel. One was barium sulfate. The other could not be identified, but it was determined that the only metal it contained was bismuth

    This report presents the results of a study of nonthermal treatment technologies. The study consisted of a systematic assessment of five nonthermal treatment alternatives. The treatment alternatives consist of widely varying technologies for safely destroying the hazardous organic components, reducing the volume, and preparing for final disposal of the contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. The alternatives considered were innovative nonthermal treatments for organic liquids and sludges, process residue, soil and debris. Vacuum desorption or various washing approaches are considered for treatment of soil, residue and debris. Organic destruction methods include mediated electrochemical oxidation, catalytic wet oxidation, and acid digestion. Other methods studied included stabilization technologies and mercury separation of treatment residues. This study is a companion to the integrated thermal treatment study which examined 19 alternatives for thermal treatment of MLLW waste. The quantities and physical and chemical compositions of the input waste are based on the inventory database developed by the US Department of Energy. The Integrated Nonthermal Treatment Systems (INTS) systems were evaluated using the same waste input (2,927 pounds per hour) as the Integrated Thermal Treatment Systems (ITTS). 48 refs., 68 figs., 37 tabs.

    Full Text Available Introduction: In HIV+ patients exhibiting multidrug resistance (MDR, NRTIs often have little activity, increased toxicity, drug interactions and add unnecessary treatment costs. The 48 week VERITAS study demonstrated that these patients can have a safe and effective simplification of salvage regimen by removing inactive NRTIs as determined by genotypic data. Virological, immunological, clinical and financial outcomes were evaluated at an additional 96 weeks of follow-up. Materials and Methods: MDR patients with an undetectable viral load (VL on a stable regimen containing at least four ARVs (including one inactive NRTI were enrolled in an open-label, prospective simplification trial, where one inactive NRTI was removed at baseline (BL. A second NRTI could be removed at week 24 if the regimen contained at least five ARVs at enrolment. Results: 31 male patients participated. The mean length of treatment was 14 years, with a median CD4 count of 525. The BL regimen consisted of 4 ARVs in 22 patients (71% and 5 ARVs in 9 patients (29%. 3TC or FTC was removed in 29 patients (94%, and either AZT or TDF was interrupted in 2 others. Four patients had a second NRTI stopped. One patient was removed at W26 as an active NRTI was removed for creatinine elevation. 30 well-controlled patients continued follow-up after W48. At W144, six patients had additional changes in their ARV regimen. Half were due to toxicity (jaundice, neuropathy and nephrotoxicity while the other half were the result of treatment simplification. None of the patients exhibited virologic failure at the time of treatment change and maintained undetectable VLs throughout the entire follow-up. These six patients had a mean gain of 79 CD4 (p=0.17 compared to baseline. 22 of the 24 patients (92% with no changes in ARV therapy after W48 had undetectable VLs. The other two had confirmed virologic failure, one with genotypic resistance. All 24 had elevated CD4 counts (mean +118 CD4, p<0.0001. No

    Bench-scale studies have been performed to find ways to produce diluted bitumen containing less than 1 per cent water. The studies showed that using diluents of high paraffin concentration and elevated solvent ratios could yield very dry diluted bitumen. The laboratory studies led to a series of pilot studies in froth treatment conducted at the facilities of the Canadian Oilsand Network for Research and Development (CONRAD). The pilot studies focused on defining the operating envelope for the Paraffin Froth Treatment Process and establishing the process` response to solvent ratio and temperature. Many different solvent materials were tested to determine their impact on process performance. The work has been part of a development plan for Oilsand leases north of Fort McMurray.

    The purpose of the Enhanced Nonthermal Treatment Systems (ENTS) study is to evaluate alternative configurations of one of the five systems evaluated in the Integrated Nonthermal Treatment Systems (INTS) study. Five alternative configurations are evaluated. Each is designed to enhance the final waste form performance by replacing grout with improved stabilization technologies, or to improve system performance by improving the destruction efficiency for organic contaminants. AU enhanced systems are alternative configurations of System NT-5, which has the following characteristics: Nonthermal System NT-5: (1) catalytic wet oxidation (CWO) to treat organic material including organic liquids, sludges, and soft (or combustible) debris, (2) thermal desorption of inorganic sludge and process residue, (3) washing of soil and inorganic debris with treatment by CWO of removed organic material, (4) metal decontamination by abrasive blasting, (5) stabilization of treated sludge, soil, debris, and untreated debris with entrained contamination in grout, and (6) stabilization of inorganic sludge, salts and secondary waste in polymer. System NT-5 was chosen because it was designed to treat combustible debris thereby minimizing the final waste form volume, and because it uses grout for primary stabilization. The enhanced nonthermal systems were studied to determine the cost and performance impact of replacing grout (a commonly used stabilization agent in the DOE complex) with improved waste stabilization methods such as vitrification and polymer.

  17. Uranium-contaminated soil pilot treatment study

    International Nuclear Information System (INIS)

    A pilot treatment study is proving to be effective for the remediation of uranium-contaminated soil from a site at the Los Alamos National Laboratory by use of a two-step, zero-discharge, 100% recycle system. Candidate uranium-contaminated soils were characterized for uranium content, uranium speciation, organic content, size fractionization, and pH. Geochemical computer codes were used to forecast possible uranium leach scenarios. Uranium contamination was not homogenous throughout the soil. In the first step, following excavation, the soil was sorted by use of the ThemoNuclean Services segmented gate system. Following the sorting, uranium-contaminated soil was remediated in a containerized vat leach process by use of sodium-bicarbonate leach solution. Leach solution containing uranium-carbonate complexes is to be treated by use of ion-exchange media and then recycled. Following the treatment process the ion exchange media will be disposed of in an approved low-level radioactive landfill. It is anticipated that treated soils will meet Department of Energy site closure guidelines, and will be given open-quotes no further actionclose quotes status. Treated soils are to be returned to the excavation site. A volume reduction of contaminated soils will successfully be achieved by the treatment process. Cost of the treatment (per cubic meter) is comparable or less than other current popular methods of uranium-contamination remediation

  20. Pharmaceutical wastewater treatment: a physicochemical study

    International Nuclear Information System (INIS)

    A physicochemical study for the treatment of pharmaceutical wastewater was performed. Objective of the laboratory investigation was to study the removal of color, Total Dissolved Solids (TDS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), turbidity and phenol and bring them up to the allowable limits for reuse purposes. Efficiency of coagulation, flocculation, sedimentation, sand filtration followed by activated carbon adsorption was determined. It was found that tested coagulants (alum, ferric chloride, and ferrous sulphate) are not much effective and required high dosage for the removal; of TSS, BOD, COD and turbidity. Alum was found to be more effective among tested coagulants and reduce TSS, BOD, COD and turbidity 79.6%, 34.8, 48.6% and 69.2% respectively. Sand filtration further reduced the studied parameters 97.7%, 95.7%, 93.9% and 76.9% respectively. As the concentration of phenol in the studied pharmaceutical wastewater was 100 mg/l, granular activated carbon was used to remove phenol up to the allowable limit for reuse purpose. Activated carbon adsorption further reduces phenol, TDS, TSS, BOD, and COD up to 99.9%, 99.1%, 21.4%, 81.3% and 71.1% respectively. High removal of color observed after activated carbon adsorption. It was concluded that the suggested treatment scheme is suitable to bring the effluent quality up to the water quality standards. (author)

    This study examined the effects of chronic deletion of circulating growth hormone-releasing (GHRH) and/or somatostatin (SRIF) on normal growing male rats, as well as the effects of exogenous GHRH (1-29)NH2 and/or SMS 201-995 administration on the growth of rats with hypothalamic ablation. Passive immunization with anti-rat GHRH goat gamma-globulin (GHRH-Ab) for 3 weeks caused a marked decrease in the levels of pituitary GH mRNA and severe growth failure. Treatment with anti-SRIF goat gamma-globulin (SRIF-Ab) for 3 weeks produced a more modest decrease in GH mRNA levels in the pituitary and a slight but significant inhibition of normal somatic growth. Hypothalamic ablation produced a marked decrease in the level of mRNA in the pituitary. Chronic continuous administration of GHRH (1-29)NH2 stimulated pituitary GH synthesis, elevated serum levels of insulin-like growth factor I and increased body weight gain in rats with hypothalamic ablation treated with replacement doses of cortisone, testosterone and L-thyroxine. Combined treatment with GHRH (1-29)NH2 and SMS 201-995 appeared to promote the effect of GHRH on pituitary GH release and somatic growth in these animals. The results suggest that continuous administration of GHRH will be useful in the treatment of children with growth retardation resulting from hypothalamic disorders. In children with combined GHRH and somatostatin deficiencies, the addition of somatostatin to a GHRH treatment regimen may produce better results. PMID:2568726

    Intravascular hemolysis in Paroxysmal nocturnal hemoglobinuria (PNH) can effectively be controlled with eculizumab, a humanized monoclonal antibody that binds complement protein C5. We report here a retrospective comparison study between 123 patients treated with eculizumab in the recent period (>2005) and 191 historical controls (from the French registry). Overall survival (OS) at 6 years was 92% (95%CI, 87 to 98) in the eculizumab cohort versus 80% (95%CI 70 to 91) in historical controls diagnosed after 1985 (HR 0.38 [0.15 to 0.94], P = 0.037). There were significantly fewer thrombotic events (TEs) in the group of patients treated with eculizumab (4% [1-10]) as compared to the historical cohort (27% [20-34]). However, we found that TEs may still occur after the initiation of eculizumab treatment and that previous TEs still have a negative impact on survival. Evolutions to myelodysplastic syndrome or acute leukemia were similar in both cohorts. There was less evolution to aplastic anemia in the treatment group. In multivariate analysis, absence of a previous TE and treatment with eculizumab were associated with a better OS. Treatment with eculizumab improves overall survival in classic PNH patients without increasing the risk of clonal evolution. Am. J. Hematol. 91:366-370, 2016. © 2016 Wiley Periodicals, Inc.

  3. PIXE studies of osteoporosis preventive treatments

    International Nuclear Information System (INIS)

    Particle induced X-ray emission (PIXE) and nuclear microprobe (NMP) have been used in an exploratory work to study elemental alterations in tissues of experimental animals submitted to osteoporosis preventive treatments. Osteopathologies have been associated with several factors, such as hormonal disturbances, metabolic aberrations, low dietary Ca and vitamin D intake, excess of iron, among other possible factors. Hormonal treatments seem to be beneficial to the incorporation of Ca in bone but breast and endometrial cancers constitute significant side effects that cannot be ignored. Wistar female rats were used to test the effect of estrogen therapy in osteoporosis progression. The variations of elemental concentrations in uterus and the Ca content of femoral bones of ovariectomised rats under estrogen therapy were investigated. PIXE, Rutherford backscattering spectrometry and secondary electron microscopy techniques were applied for the characterisation of biological materials, with respect to morphology and trace element distribution determination. The increase of Ca and Fe concentrations in uterus and the variations for Ca distribution patterns in bone of rats submitted to estrogen therapy were the major features observed

    Full Text Available To compare changes in gene expression by microarray from subcutaneous adipose tissue from HIV treatment naïve patients treated with efavirenz based regimens containing abacavir (ABC, tenofovir (TDF or zidovidine (AZT.Subcutaneous fat biopsies were obtained before, at 6- and 18-24-months after treatment, and from HIV negative controls. Groups were age, ethnicity, weight, biochemical profile, and pre-treatment CD4 count matched. Microarray data was generated using the Agilent Whole Human Genome Microarray. Identification of differentially expressed genes and genomic response pathways was performed using limma and gene set enrichment analysis.There were significant divergences between ABC and the other two groups 6 months after treatment in genes controlling cell adhesion and environmental information processing, with some convergence at 18-24 months. Compared to controls the ABC group, but not AZT or TDF showed enrichment of genes controlling adherence junction, at 6 months and 18-24 months (adjusted p<0.05 and focal adhesions and tight junction at 6 months (p<0.5. Genes controlling leukocyte transendothelial migration (p<0.05 and ECM-receptor interactions (p = 0.04 were over-expressed in ABC compared to TDF and AZT at 6 months but not at 18-24 months. Enrichment of pathways and individual genes controlling cell adhesion and environmental information processing were specifically dysregulated in the ABC group in comparison with other treatments. There was little difference between AZT and TDF.After initiating treatment, there is divergence in the expression of genes controlling cell adhesion and environmental information processing between ABC and both TDF and AZT in subcutaneous adipose tissue. If similar changes are also taking place in other tissues including the coronary vasculature they may contribute to the increased risk of cardiovascular events reported in patients recently started on abacavir-containing regimens.

    1995-12-01

    A new treatment for HIV-related idiopathic thrombocytopenia purpura (ITP) has been developed. The treatment, WinRho SDTM, is a form of the intravenous immunoglobulin, IVIG. IVIG has been successful at reducing the ability of HIV antibody-fragment clusters to bind to platelets, thus preventing the body from destroying the platelets prematurely. WinRho SD was effective for HIV patients whether they were taking AZT or not. Minor side effects developed following four percent of the infusions. Anemia caused by hemolysis can also be a problem. Suggested dosing is set at 250 IU (50mg/kg bodyweight), and the infusions take about three to five minutes, as opposed to several hours for other IVIG forms. PMID:11363105

  8. A microbiological study on sewage sludge treatment

    International Nuclear Information System (INIS)

    Isolation and identification of salmonellae in sewage sludge cake and radiation sensitivities of the isolated strains were studied. Disinfection of the sludge by heat or radiation and effect of such treatment on composting were also carried out. Five groups of O-antigen and seven serotypes of salmonellae were identified from the sludge cakes. D10 values of the salmonellae in phosphate buffer were ranged from 0.16 to 0.22 kGy and those in sludge were about three times larger. Total bacterial counts and coliforms in the sludges were determined to be 4.6 x 107 - 5.1 x 109 and 1.3 x 105 - 1.1 x 109 colony forming unit (cfu/g). After irradiation at 20 kGy by gamma ray or electron beam, decrease of total bacterial count was 5 - 7 log cycles and a dose of 5 kGy was enough to eliminate all of the coliforms. Coliforms decreased rapidly by heating at 65degC, but only one log cycle decrease was observed in total bacterial count. By heating at 100degC, total bacterial count decreased rapidly. Two peaks were observed in CO2 evolution curves of radiation disinfected sludge composting, but only one peak in heat disinfected sludge composting. (author)

    Objective: To describe the treatment outcomes in terms of adherence, outcomes and side effects of antiretroviral (ARV) agents. Study Design: An observational study. Place and Duration of Study: Teaching Hospital of Khyber Medical University, Institute of Medical Sciences, Kohat, from February 2007 to December 2012. Methodology: Human Immunodeficiency Virus (HIV) positive patients, taking 1st line ARV agents for at least 6 months were included. Adherence was calculated by self report on asking the number of doses missed in last 30 days. ARVs were provided on monthly basis. Adherence data was noted over a period of 6 months. ARVs outcomes were recorded in the form of adherence, CD4 count, functional status of the patient, change in weight, further transmission of the disease, number of hospital admissions and deaths. Adverse Drug Reactions (ARDs) to ARVs were assessed clinically and by laboratory markers. Mean and standard deviation were calculated for numerical variables while frequencies and percentages were calculated for categorical variables. Results: Total number of patients included in this study were 107. Out of them, 66.4% were males and 33.6% were females. The mean age was 39.9 +- 13.80 years. Patients taking AZT/3TC/NVP, AZT/3TC/EFZ, D4T/3TC/NVP, D4T/3TC/EFZ, TNF/3TC/NVP or EFZ were 49.5%, 22.4%, 10.3%, 4.7% and 13% respectively. Most adverse affects were observed in 10 days to 90 days of initiation of therapy. Rash was observed in 71 (66.4%) patients, anaemia in 4 (3.7%) patients while only one patient (0.93%) had nausea / vomiting. Thirty (28%) patients reported no side effects. Out of 107 patients, 98 (91.5%) were alive whereas 9 (8.4%) died at the end of the study period. Twelve patients had one hospital admission (11.21%) whereas 9 (8.4%) patients had two admissions during the study period. The first mean CD4 was 325.27 cells /mcL whereas mean last CD4 count was 389.86 cells/mcL. Conclusion: ARVs have very satisfactory outcomes in HIV/AIDS patients

    Loiudice, T.A.; Lang, J.A.

    1983-08-01

    Twenty-four patients with severe radiation injury to the small bowel seen over a 4-year period were randomized to four treatment groups: 1) methylprednisolone 80 mg intravenously plus Vivonex-HN, 2 L/day po, 2) methylprednisolone 80 mg intravenously plus total parenteral nutrition, 2.5 L/day, 3) total parenteral nutrition, 2.5 L/day, and 4) Vivonex-HN, 2 L/day po. Patients received nothing by mouth except water in groups II and III, and only Vivonex-HN in groups I and IV. Patients were treated for 8-wk periods. Improvement was gauged by overall nutritional assessment measurements, nitrogen balance data and by radiological and clinical parameters. No significant difference between groups I, II, III, and IV could be found for age, sex, mean radiation dosage, time of onset after radiation therapy, or initial nutritional assessment data. Differences statistically could be found between groups II and III and I and IV regarding nutritional assessment data, nitrogen balance, radiographic and clinical parameters after therapy, with marked improvement noted in groups II and III. We conclude that a treatment regimen consisting of total parenteral nutrition and bowel rest is beneficial in the treatment of radiation enteritis. Methylprednisolone appears to enhance this effect and indeed, may be responsible for a longer lasting response.

    Full Text Available Biogas is more and more used as an alternative source of energy, considering the fact that it is obtained from waste materials and it can be easily used in cities and rural communities for many uses, between which, as a fuel for households. Biogas has many energy utilisations, depending on the nature of the biogas source and the local demand. Generally, biogas can be used for heat production by direct combustion, electricity production by fuel cells or micro-turbines, Combined Hest and Power generation or as vehicle fuel. In this paper we search for another uses of biogas and Anaerobe Digestion substrate, such as: waste water treatment plants and agricultural wastewater treatment, which are very important in urban and rural communities, solid waste treatment plants, industrial biogas plants, landfill gas recovery plants. These uses of biogas are very important, because the gas emissions and leaching to ground water from landfill sites are serious threats for the environment, which increase more and more bigger during the constant growth of some human communities. That is why, in the developed European countries, the sewage sludge is treated by anaerobe digestion, depending on national laws. In Romania, in the last years more efforts were destined to use anaerobe digestion for treating waste waters and management of waste in general. This paper can be placed in this trend of searching new ways of using with maximum efficiency the waste resulted in big communities.

    Full Text Available Fifteen cases of keratoconjunctivitis sicca (KCS of unknown etiology were treated with soft contact lenses for the purpose of their bandage effects and moisuture supply. A soft contact lens was worn on one of the eyes of each case but not on the other to compare its effectiveness. New opthalmic drops or contact lens wearers were dropped in both eyes. Furthermore, the KCS-index was worked out on the basis of the complaints of 23 patients of KCS of unknouwn etiology. The indexes before and after treatment were compared. Corneal objective findings were improved in all the eyes wearing soft contact lensen for along period, and seven stopped wearing them although corneal objective findings were much better, because they had some troubles with handlings were much better, because they had some troubles with handling the lenses, because they had lost rhem, or because their visual acuity decreased while wearing the lenses. Forlong term wearing the flattest lenses should be used in the beginning and changed gradually to lenses of greater curvature which are better able to keep their centering. Then immediately after successful fitting, the lenses should be given appropriate refractive power. The new ophthalmic drops for soft contact lens wearers were very much effective as artificial tears to both eyes with and without sofy contact lenses. KCS-indexes were numerical values relating to patients subjective symptoms. KSC-indexes improves by an average of +6.4±7.5 after treatment. On the other hand, KCS-indexes improved by +10.7±7.9 in the group that succeeded in wearing SCL for a long period, and by +7.6±2.1 even in the group that failed.

    1997-04-01

    This report describes the process modeling done in support of the Integrated Nonthermal Treatment System (INTS) study. This study was performed to supplement the Integrated Thermal Treatment System (ITTS) study and comprises five conceptual treatment systems that treat DOE contract-handled mixed low-level wastes (MLLW) at temperatures of less than 350{degrees}F. ASPEN PLUS, a chemical process simulator, was used to model the systems. Nonthermal treatment systems were developed as part of the INTS study and include sufficient processing steps to treat the entire inventory of MLLW. The final result of the modeling is a process flowsheet with a detailed mass and energy balance. In contrast to the ITTS study, which modeled only the main treatment system, the INTS study modeled each of the various processing steps with ASPEN PLUS, release 9.1-1. Trace constituents, such as radionuclides and minor pollutant species, were not included in the calculations.

A field study with a 2 X 2 design (treatment: drug-free vs. drug-regime and (treatment phase: initial phase vs. maintenance in drug treatment was carried out. The results support the hypothesis of a dual diagnosis, that is, the comorbidity of psychopathology and drug addiction. On the whole, treatment for drug addiction had a significant impact on reducing associated psychopathology. Finally, the results are discussed in the light of the implications for the treatment of drug addiction.

  5. Studies of testicular function after treatment for testicular tumor, 1

    International Nuclear Information System (INIS)

    Recently, the treatment for testicular tumor has improved. Preservation of testicular function in the treatment of testicular tumor is important, because the majority of the patients are young. We investigated the testicular function of patients with testicular tumor before, during and after treatment. As a part of this study, the fertility of patients with testicular tumor before and after treatment was evaluated. 1. Fourteen of 78 married patients (18 %) showed sterility for two or more years before treatment. 2. When semen was examined in 31 patients before treatment, only seven patients (23 %) showed normal sperm counts of more than 40 x 106/ml, and 19 (61.3 %) showed oligospermia or azoospermia with sperm counts of less than 10 x 106/ml. 3. Of 20 patients who underwent retroperitoneal lymphnode dissection, 15 developed ejaculation deficiency. Four other patients also developed ejaculation deficiency but recovered, and three of them rendered their wives pregnant. 4. Of 23 patients given radiotherapy, nine produced children both before and after treatment, nine produced children before treatment but showed sterility after treatment, and five showed sterility both before and after treatment. 5. Examination of semen was performed in 17 patients given radiotherapy and in five given chemotherapy. Many patients developed oligospermia or azoospermia after the treatments, but revealed a tendency to recover with time. Based on the results mentioned above, it is inferred that the ability to produce sperm in patients with testicular tumor after treatment decreases but the decrease tends to recover to normal with time.

    Full Text Available The aim of the paper is to present the conducted analyses of pre-feasibility study of different approaches for wastewater management in a settlement of 180 persons. In the assessment both technical and economic aspects were analyzed. The costs were calculated for three different and, at the same time, most popular as well as possible technical solutions like: (i construction of local wastewater treatment plant with gravitational and pressurized networks, (ii construction of single family wastewater treatment plants, (iii construction of sealed septic tanks. Carried out analyses of investment and maintenance costs revealed that at the stage of construction the most expensive is local sewer network with treatment plant, while the construction of a single family treatment plant has similar cost regardless of the technology used. When the long term operation and investment cost are accounted the most economical reasonable solution is the application of wetland treatment for household wastewater treatment.

    Oxaliplatin in combination with 5-fluorouracil/leucovorin (LV5FU) improves the response rate and survival of patients with metastatic colorectal cancer. The objective of the Mosaic study was to evaluate the efficacy of this association in the adjuvant treatment of stage II and III colon cancer. This international study, including 2,246 patients, compared the efficacy of standard treatment with LV5FU2 alone to that of oxaliplatin-LV5FU (Folfox4 regimen) following R0 resection of the primary tumour. Both treatments were administered every two weeks for six months. At 3-year follow-up, the risk of relapse was decreased by 23% in the Folfox4 group (p = 0.002). The protocol was well tolerated, with an identical overall mortality during treatment (0.5%) in both groups. The main specific complication, peripheral sensory neuropathy was reversible in the great majority of cases. A new analysis at 4-year follow-up (median 48.6 months) confirmed the superior efficacy of the Folfox4 regimen compared to the standard treatment, the reduction in relapse risk being 24% (p = 0.0008). On the strength of these results, oxaliplatin was granted a marketing authorization for the indication adjuvant treatment of stage III colon cancer. Based on the data currently available, physicians should consider adjuvant treatment for stage II patients, making each individual decision for treatment on a case-by-case basis. PMID:16483940

    An emerging body of literature identifies substance use as a growing concern among refugees resettling in the United States. Like immigrants, refugees may face cultural, linguistic, or systems barriers to connecting with mainstream substance use treatment programs, which may be compounded by refugees' unique experiences with exposure to trauma, displacement in refugee camps, and resettlement. This qualitative study explores factors that support and prevent refugees from connecting with chemical health treatment. Fifteen participants who identified as social service or public health professionals who work with refugees responded to an online, semistructured survey about their experiences referring refugees to substance use treatment. Resulting data was analyzed using thematic analysis. Themes emerged identifying a lack of culturally informed treatment models, policy issues, and client characteristics such as motivation and past trauma as barriers to engaging with treatment. Ongoing case management and coordination were identified as important to successful linkage. Findings from this study contribute to a better understanding of how to support refugees seeking substance use treatment and suggest that developing trauma informed, culturally relevant models of treatment that are integrated with primary health care and geographically accessible may enhance treatment linkage.

    A literature review performed by the EXtracorporeal TReatments In Poisoning (EXTRIP) workgroup highlighted deficiencies in the existing literature, especially the reporting of case studies. Although general reporting guidelines exist for case studies, there are none in the specific field of...... extracorporeal treatments in toxicology. Our goal was to construct and propose a checklist that systematically outlines the minimum essential items to be reported in a case study of poisoned patients undergoing extracorporeal treatments. Through a modified two-round Delphi technique, panelists (mostly chosen...... reports containing data on extracorporeal treatments in poisoning published in Medline in 2011 were reviewed during the external validation rounds. Twenty-one panelists (20 from the EXTRIP workgroup and an invited expert on pharmacology reporting guidelines) participated in the modified Delphi technique...

    This report presents the second phase of a study on thermal treatment technologies. The study consists of a systematic assessment of nineteen thermal treatment alternatives for the contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. The treatment alternatives consist of widely varying technologies for safely destroying the hazardous organic components, reducing the volume, and preparing for final disposal of the MLLW. The alternatives considered in Phase 2 were innovative thermal treatments with nine types of primary processing units. Other variations in the study examined the effect of combustion gas, air pollution control system design, and stabilization technology for the treatment residues. The Phase 1 study examined ten initial thermal treatment alternatives. The Phase 2 systems were evaluated in essentially the same manner as the Phase 1 systems. The alternatives evaluated were: rotary kiln, slagging kiln, plasma furnace, plasma gasification, molten salt oxidation, molten metal waste destruction, steam gasification, Joule-heated vitrification, thermal desorption and mediated electrochemical oxidation, and thermal desorption and supercritical water oxidation. The quantities, and physical and chemical compositions, of the input waste used in the Phase 2 systems differ from those in the Phase 1 systems, which were based on a preliminary waste input database developed at the onset of the Integrated Thermal Treatment System study. The inventory database used in the Phase 2 study incorporates the latest US Department of Energy information. All systems, both primary treatment systems and subsystem inputs, have now been evaluated using the same waste input (2,927 lb/hr). 28 refs., 88 figs., 41 tabs.

    Plaque-induced gingivitis can be alleviated by various treatment regimens. To probe the impacts of various anti-gingivitis treatments on plaque microflora, here a double blinded, randomized controlled trial of 91 adults with moderate gingivitis was designed with two anti-gingivitis regimens: the brush-alone treatment and the brush-plus-rinse treatment. In the later group, more reduction in both Plaque Index (TMQHI) and Gingival Index (mean MGI) at Day 3, Day 11 and Day 27 was evident, and more dramatic changes were found between baseline and other time points for both supragingival plaque microbiota structure and salivary metabonomic profiles. A comparison of plaque microbiota changes was also performed between these two treatments and a third dataset where 50 subjects received regimen of dental scaling. Only Actinobaculum, TM7 and Leptotrichia were consistently reduced by all the three treatments, whereas the different microbial signatures of the three treatments during gingivitis relieve indicate distinct mechanisms of action. Our study suggests that microbiota based signatures can serve as a valuable approach for understanding and potentially comparing the modes of action for clinical treatments and oral-care products in the future.

Corrosion resistance was investigated using potentiodynamicmethod. Chemical composition of the samples surface was measured using SEM EDX. Surface roughness andtopography was analyzed using AFM. Bioactive properties were analyses on the basis of the chemical compositionof the samples immersed in HBSS for 14 days.Findings: The chemical composition analysis of the samples showed that alkali treatment increased significantlynickel content in top layer and also increase in roughness was observed. Spark oxidation results also in roughnessincrease. Corrosion test showed insignificant increase of the corrosion resistance after oxidation while alkalitreatment caused drop of the resistance. Bioactivity study revealed that both applied treatments did not improvebioactive properties of the NiTinol when compared with simply ground samples.Research limitations/implications: Two types of the treatment applied for nickel titanium and intended toimprove bioactive properties were investigated. There was no improvement in bioactivity observed after surfacetreatment. However, alternation in chemical composition, corrosion resistance, and topography were observed.Further analysis of biocompatibility and mechanical properties are required.Practical implications: Both chemical and electrochemical treatment, as presented in the paper, gave promisingresults in terms of wetting ability, topography and apatite film formation, however further study are required toconfirm suitability of the treatments for medical applications.Originality/value: The obtained results revealed unsuitability of the alkali treatment intended to improvebioactivity of the

  8. Preliminary study of interventional treatment for tubal pregnancy

    International Nuclear Information System (INIS)

    Objective: To study the clinical value and methods of interventional treatment for tubal pregnancy. Methods: Two different methods were used in the interventional treatment of 18 patients with tubal pregnancy, which were transvaginal tubal intra-gestational methotrexate (MTX) injection and intra-utero-arterial MTX infusion. The former was selected for the treatment of 8 patients and the latter for 10 patients. Cook-fallopian tube catheterization set and the general angiographic catheters of 4.1 Fr Cobra were used. After the treatment, conditions of the patients, β-HCG level and ultrasound changes of the pregnant bladder were the main indexes for monitoring the therapeutic effect in this study. Results: The successful rate, cure rate, embryo killing rate reached 100%, 88.9%(16/18) and 94.4% (17/18) respectively. Two cases of intra-utero-arterial MTX infusion treatment failed, β-HCG was reduced to normal level with an average of 11.2 +- 11.6 d (3-28 d). In 10 cases, the ultrasound showed that the pregnancy bladder disappeared in 2-3 weeks, accounting for 76.9% (10/13). The longest time was 60 days. The range of menstruation recovery was 37 +- 9 d (21-50 d). Conclusions: Interventional treatment of tubal pregnancy is effective, reliable and easy for operation. It will be especially effective by arterial procedure. Interventional treatment will be a important method for terminating tubal pregnancy

Patients with anorexia nervosa strive for thinness in order to obtain self-control and are ambivalent toward change and toward treatment. In order to achieve a greater understanding of patients' own understanding of their situation, the aim of this study was to examine the expectations of potential anorexic patients seeking treatment at a specialized eating-disorder unit.Methods: A qualitative study design was used. It comprised 15 women between 18 and 25 years of age waiting to be assessed before treatment. The initial question was, "What do you expect, now that you are on the waiting list for a specialized eating-disorder unit?" A content analysis was used, and the text was coded, categorized according to its content, and further interpreted into a theme.Results: From the results emerged three main categories of what participants expected: "treatment content," "treatment professionals," and "treatment focus." The overall theme, "receiving adequate therapy in a collaborative therapeutic relationship and recovering," described how the participants perceived that their expectations could be fulfilled.Discussion: Patients' expectations concerning distorted thoughts, eating behaviors, a normal, healthy life, and meeting with a professional with knowledge and experience of eating disorders should be discussed before treatment starts. In the process of the therapeutic relationship, it is essential to continually address patients' motivations, in order to understand their personal motives behind

    Background and Objectives: Various extraction protocols have been followed for successful orthodontic treatment. The purpose of this study was to evaluate the extraction protocols in patients who had previously undergone orthodontic treatment and also who had reported for continuing orthodontic treatment from other clinics. Materials and Methods: One hundred thirty eight patients who registered for orthodontic treatment at the Faculty of Dentistry were divided into 10 extraction protocols based on the Orthodontic treatment protocol given by Janson et al. and were evaluated for statistical significance. Results: The descriptive statistics of the study revealed a total of 40 (29%) patients in protocol 1, 43 (31.2%) in protocol 2, 18 (13%) in protocol 3, 16 (11.6%) in protocol 5, and 12 (8.7%) in Type 3 category of protocol 9. The Type 3 category in protocol 9 was statistically significant compared to other studies. Midline shift and collapse of the arch form were noticed in these individuals. Conclusion: Extraction of permanent teeth such as canine and lateral incisors without rational reasons could have devastating consequences on the entire occlusion. The percentage of cases wherein extraction of permanent teeth in the crowded region was adopted as a treatment option instead of orthodontic treatment is still prevalent in dental practice. The shortage of orthodontists in Malaysia, the long waiting period, and lack of subjective need for orthodontic treatment at an earlier age group were the reasons for the patient's to choose extraction of the mal-aligned teeth such as the maxillary canine or maxillary lateral incisors.

    Topographical disorientation refers to individuals who are unable to find their way around large-scale environments in a normal manner. Childhood topographical disorientation is rarely investigated or reported. Treatment of topographical disorientation is also rare with only one reported treatment study in an adult (Davis & Coltheart, 1999) and no known description of treatment in a child. This paper reports a detailed case analysis of CA, a 6-year-old child with topographical disorientation, and a description of a treatment programme focused on training orientation in the school environment. Assessment of CA revealed mild to moderate visual agnosia in conjunction with severe impairments in general spatial learning and memory, topographical new learning and memory, and a total inability to learn new topographical routes. CA was also unable to use a mental image of his environment, a simple visual plan of his environment or a simple visual map, but was able to follow verbally mediated topographical instructions. The treatment programme focused on improving CA's topographical orientation in the school environment. The programme first involved training in recognition of major school buildings and landmarks and then focused on practical training in route finding along commonly used routes in the school environment. Clear benefits from treatment were evident. The assessment and treatment methods employed provide practical and useful ideas for management of this condition in other children. PMID:17178605

  16. A study of the treatment method of cerebral artery dissection

    International Nuclear Information System (INIS)

    Objective: To explore the best treatment method of cerebral artery dissection. Methods: This study included eight patients who were definitely diagnosed as cerebral artery dissection by the cerebral angiography in our department of neurology during Oct. 2009 and Nov. 2011. They were all treated by the anticoagulation or anti-platelet methods. Some patients received the stent therapy. All patients' were followed for at least three months. The treatment effect was assessed by NIHSS, mRS and by the cerebral angiography. Results: Six patients had carotid artery dissection, 2 had vertebral artery dissection. Four patients were given anticoagulant therapy and the other 4 were given anti-platelet therapy. The reexamination by angiography 10-14 days after admission showed that in 3 patients, the stenosis was aggravated or the infarction occurred. They were diagnosed as having repeated transient ischemic attack (TIA) during pharmacotherapy and received stents for treatment. There was no TIA and cerebral infarction in the follow-up period after individualized therapy. Mean NIHSS scores of 8 patients between pre and post treatment were 5.9, 1.6 respectively. Mean mRS scores pre and post treatment were 2.5, 0.9 respectively. Conclusion: The treatment for patients with cerebral artery dissection should be individuated. The patients in acute stage should get anticoagulation, anti-platelet therapy and angiography re-examination. According to the clinical manifestation and cerebral angiography, the next step for the treatment should be done. (authors)

    Currently, the choice of tactics of treatment of the patient with prostate cancer (PCa) requires to take into account the degree of differentiation and stage of tumor, age of the patient and his somatic diseases, the risk of complications, as well as the patient's desire and physician's experience. Due to the progressive development of medical technology, interest in minimally invasive treatments for prostate cancer, such as cryoablation, interstitial brachytherapy and HIFU-therapy, has grown. Cryoablation of the prostate gland is a tissue ablation by local effects of very low temperatures and is minimally invasive, highly effective treatment for prostate cancer that can be used as the primary treatment, and in the case of tumor recurrence after radiotherapy. Focal cryoablation of the prostate allows to selectively destroy the known tumor with preservation of organ function and without reducing the quality of life of the patient. Focal therapy for prostate cancer is an alternative to radical treatment and active surveillance, occupying an intermediate position between them. Due to the lack of long-term results, focal cryoablation is an experimental type of treatment. First cryoablation of the prostate using modern equipment was carried out in Russia in March 2010, at the Department of Urology MSMSU. Since that time, we performed this procedure in 122 patients with prostate cancer; cryoablation was primary treatment in 110 patients and was used as salvage treatment in 12 patients. In most cases, the operation was performed under epidural or spinal anesthesia. According to the protocol, all the patients underwent 2 cycles of freezing and thawing under transrectal ultrasound guidance. A significant improvement of equipment for cryosurgery, the use of cryoneedles with smaller diameter, and the use of temperature sensors and catheters to warm the urethral mucosa have allowed to minimize the number of complications in comparison with other methods of treatment of

    Full Text Available Abstract: Food processing industrial wastewater is well known for its high concentration of COD, BOD and suspended solid. The condition of the wastewater formed makes it illegal for the industry to release the wastewater to the open body of water without essential treatment. The study is conducted on food manufacturing company which specializes in chips export business. The quality of the wastewater produced from the manufacturing is not appropriate to be discharged directly. Thus, a two phase treatment system involving UASB and HUASB reactors as primary treatment and followed by AF reactor as secondary treatment is proposed. Basically, this research will focus on the performance of UASB-AF and HUASB-AF treatment systems and the affect of adding palm oil shell into the HUASB and AF respectively as support media. Parameters measured are pH, COD, NH3-N, oil and grease and total phosphorus. The instruments used for collecting data in this research are pH meter and HACH DR5000. In this research, the highest COD removal for the effluents from the U1 and U2 were at the 14th day with 93.6% removal and at the 62th day with 96.6% each. Meanwhile, in the R2 treatment system, the highest COD removal for the effluents from the H1 and H2 were at the 14th day with 98.3% removal and at 110th day with 97.6% removal. It is hoped that this study will generate useful findings that could be applied to alleviate the current problem at the food factory and also at other food industry in the future.

  7. Process modeling for the Integrated Thermal Treatment System (ITTS) study

    International Nuclear Information System (INIS)

    This report describes the process modeling done in support of the integrated thermal treatment system (ITTS) study, Phases 1 and 2. ITTS consists of an integrated systems engineering approach for uniform comparison of widely varying thermal treatment technologies proposed for treatment of the contact-handled mixed low-level wastes (MLLW) currently stored in the U.S. Department of Energy complex. In the overall study, 19 systems were evaluated. Preconceptual designs were developed that included all of the various subsystems necessary for a complete installation, from waste receiving through to primary and secondary stabilization and disposal of the processed wastes. Each system included the necessary auxiliary treatment subsystems so that all of the waste categories in the complex were fully processed. The objective of the modeling task was to perform mass and energy balances of the major material components in each system. Modeling of trace materials, such as pollutants and radioactive isotopes, were beyond the present scope. The modeling of the main and secondary thermal treatment, air pollution control, and metal melting subsystems was done using the ASPEN PLUS process simulation code, Version 9.1-3. These results were combined with calculations for the remainder of the subsystems to achieve the final results, which included offgas volumes, and mass and volume waste reduction ratios

  17. Vitrification treatability studies of actual waste water treatment sludges

    International Nuclear Information System (INIS)

    Treatability studies have been conducted at the laboratory-scale to evaluate vitrification of waste water sludges at the Oak Ridge Reservation (ORR). These studies are being conducted jointly by Westinghouse Savannah River Technology Center (SRTC) and Oak Ridge National Laboratory (ORNL). These studies include testing with surrogate waste formulations at both the laboratory-scale and pilot-scale, and testing with actual waste at the laboratory-scale, pilot-scale, and field-scale. ORR was chosen as the host site for the field-scale demonstration. The Y12 West End Treatment Facility (WETF) waste water treatment sludges, which are RCRA F-listed wastes, were chosen as the candidate waste stream for the first field-scale demonstration. The laboratory-scale ''proof-of-principle'' demonstrations reported in this study and the pilot-scale studies planned for FY95 on the WETF sludge will provide needed operating parameters for the planned field-scale demonstration. These laboratory-scale ''proof-of-principle'' and pilot-scale studies also provide needed data for the evaluation of the feasibility of vitrification as a stabilization option for a variety of wastes which do not currently meet RCRA/LDR (Resource Conservation and Recovery Act/Land Disposal Restrictions) requirements for storage/disposal and/or those for which treatment capacity does not presently exist

  18. Performance of small water treatment plants: The case study of Mutshedzi Water Treatment Plant

    Makungo, R.; Odiyo, J. O.; Tshidzumba, N.

    The performance of small water treatment plants (SWTPs) was evaluated using Mutshedzi WTP as a case study. The majority of SWTPs in South Africa (SA) that supply water to rural villages face problems of cost recovery, water wastages, limited size and semi-skilled labour. The raw and final water quality analyses and their compliance were used to assess the performance of the Mutshedzi WTP. Electrical conductivity (EC), pН and turbidity were measured in the field using a portable multimeter and a turbidity meter respectively. Atomic Absorption Spectrometry and Ion Chromatography were used to analyse metals and non-metals respectively. The results were compared with the Department of Water Affairs (DWA) guidelines for domestic use. The turbidity levels partially exceeded the recommended guidelines for domestic water use of 1 NTU. The concentrations of chemical parameters in final water were within the DWA guidelines for domestic water use except for fluoride, which exceeded the maximum allowable guideline of 1.5 mg/L in August 2009. Mutshedzi WTP had computed compliance for raw and final water analyses ranging from 79% to 93% and 86% to 93% throughout the sampling period, respectively. The results from earlier studies showed that the microbiological quality of final water in Mutshedzi WTP complied with the recommended guidelines, eliminating the slight chance of adverse aesthetic effects and infectious disease transmission associated with the turbidity values between 1 and 5 NTU. The study concluded that Mutshedzi WTP, though moving towards compliance, is still not producing adequate quality of water. Other studies also indicated that the quantity of water produced from Mutshedzi WTP was inadequate. The findings of the study indicate that lack of monitoring of quantity of water supplied to each village, dosage of treatment chemicals, the treatment capacity of the WTP and monitoring the quality of water treated are some of the factors that limit the performance of

    An integrated systems engineering approach is used for uniform comparison of widely varying thermal treatment technologies proposed for management of contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. Ten different systems encompassing several incineration design options are studied. All subsystems, including facilities, equipment, and methods needed for integration of each of the ten systems are identified. Typical subsystems needed for complete treatment of MLLW are incoming waste receiving and preparation (characterization, sorting, sizing, and separation), thermal treatment, air pollution control, primary and secondary stabilization, metal decontamination, metal melting, mercury recovery, lead recovery, and special waste and aqueous waste treatment. The evaluation is performed by developing a preconceptual design package and planning life-cycle cost (PLCC) estimates for each system. As part of the preconceptual design process, functional and operational requirements, flow sheets and mass balances, and conceptual equipment layouts are developed for each system. The PLCC components estimated are technology development, production facility construction, pre-operation, operation and maintenance, and decontamination and decommissioning. Preconceptual design data and other technology information gathered during the study are examined and areas requiring further development, testing, and evaluation are identified and recommended. Using a qualitative method, each of the ten systems are ranked.

  2. Comparative study of conformal versus intensity modulated radiotherapy treatment plans

    International Nuclear Information System (INIS)

    Full text: In order to establish some early clinical experience in the use of intensity modulated radiotherapy (IMRT) as an alternative treatment method to conformal irradiation, we selected a number of specifically difficult clinical cases to compare. Complex tumour shapes located in the skull (two cases), close to the spinal cord (two cases) and one standard prostate case were chosen for this study. A Varian CadPlan system is used for the conformal treatment plans and Helios for the IMRT plans. In both these techniques, the linear accelerator multileaf collimator system is used to shape the beam about the target volume. The Royal North Shore Hospital Varian Clinac 600C/D linear accelerator also has dynamic multileaf collimator control (DMLC) capabilities for IMRT. The five cases reported here were planned by the radiation therapists for conformal treatment and then re-planned by physics using the CadPlan's Helios inverse planning option to produce an alternative IMRT plan. Both planners worked independently of each other. Treatment set-up errors were not considered as part of this study but it is apparent here that positional errors and immobilisation are particularly important factors to consider. An allowance for all errors must therefore be included for all critical organ outlines as well as the target volume for both the conformal or IMRT treatments. Visually, the covering of regularly shaped treatment volumes for the IMRT plans was improved marginally over the conformal plan. However, complex treatment volumes (such as the posterior orbital region with surrounding critical structures) showed very clear improvements. The IMRT dose drop-off at the edge of the target volume was not as sharp as the conformal equivalent. The dose-volume-histogram (DVH) provides a limited analytical tool to quantify these observations. The DVH generally indicated similar curves for the IMRT and conformal target volume but significant IMRT improvements in limiting the dose to

  3. The treatment of contaminated sodium: a literature study

    International Nuclear Information System (INIS)

    At the Belgian Nuclear Research Centre SCK-CEN, several experiments concerning safety aspects of Liquid Metal Fast Breeder reactors were carried out. During these experiments, an important amount of sodium containing waste was produced. In view of the treatment of this waste, a literature study was performed and third parties were contacted to find a solution. This document summarizes the results of this study. The sodium waste has been characterized by a theoretical study and by radiological measurements. The waste consists mainly of metallic sodium contaminated with corrosion activation products, fission products and even fuel particles. The sodium might also be contaminated with oxidation and reduction products like Na2O and NaH. The most important contaminant is 137Cs. Several third parties, with experience in treating sodium, were contacted and they proposed a treatment of the sodium based on its reaction with water or alcohol. From a safety point of view, these reactions are not satisfactory because they are all exothermic and lead to flammable products or even make use of flammable reactants. Therefore, all the parties foresee extensive and expensive studies prior to the treatment. The urgent nature of the issues together with the important safety aspects were the incentives for the Research and Development group of the Radioactive Waste and Cleanup to look for alternatives. For this purpose, a research programme has been started with the aim to define, test, demonstrate and finally apply a safe process for the treatment of contaminated sodium by oxidation on a fluidized bed followed by vitrification. The collected information confirms that the oxidation of sodium vapour can be carried out safely, leading to the formation of sodium peroxide and oxide

One consequence of this focus is the recognition that schizophrenic illness is broader than the diagnostic entity of schizophrenia itself, and instead consists of a “spectrum” of related disorders. Because some of the symptoms in these disorders differ from each other, they provide an opportunity to determine which ones reflect a common etiology. T...

    2014-08-01

    Full Text Available BACKGROUND: This study was carried out to evaluate possible differences of pre and post treatment parameters between patients undergoing injection Sclerotherapy, rubber band ligation and hemorrhoidectomy. METHODS: The prospective study was carried out in 150 patients of haemorrhoids during August 2010 to November 2012. Each group of 50 patients treated with injection sclerotherapy, band ligation and haemorrhoidectomy and followed up for 1 year for complications. RESULTS: In the present study pain, bleeding and urinary retention were common following haemorrhoidectomy. One patient had anal incontinence post sclerotherapy. Anal incontinence was found to be a major problem in post haemorrhoidectomy period. Two patients had anal stenosis after haemorrhoidectomy. Second setting required in 6 patients of sclerotherapy and 4 patients of rubber band ligation. No recurrence noted in haemorrhoidectomy patients. Following sclerotherapy, 35 (70% patients resolved, 9 (18% improved and 3 (6% remained unchanged. Following rubber band ligation, 32 (64% resolved, 12 (24% improved and 3 (6% unchanged, while after haemorrhoidectomy, 37 (74% resolved and 10 (20% improved. DISCUSSION: Injection sclerotherapy remains the choice in first degree haemorrhoids. Rubber band ligation can be considered as first line of treatment for second degree haemorrhoids and few cases of third degree haemorrhoid. Conservative methods are acceptable to patients in outcome and in patient compliance, but repetitions of treatment may be needed. Haemorrhoidectomy remains the only form of therapy with lasting results. Thus it should be considered for all cases of third and fourth degree haemorrhoids and for uncontrollable symptomatic recurrences following conservative procedures

    Full Text Available Nowadays, water resources shortage is one of the most important issues for environmental engineers and managers as well as its conservation due to population growth and ever-increasing water demands. Besides, hospital wastewater has the same quality as municipal wastewater, but may also potentially contain various hazardous components. In this paper, physical and chemical specifications of produced wastewater in hospitals of Iran were investigated experiments. Results were compared with the effluent parameters of wastewater standards of Iranian Department of the Environment. 70 governmental hospitals from different provinces of Iran were selected by purposive (non-random sampling method. For data analysis, SPSS and EXCEL softwares were applied. The findings of the study showed that 52% of the surveyed hospitals were not equipped and 48% were equipped with wastewater treatment systems. The mean of Biochemical Oxygen Demand, Chemical Oxygen Demand and Total Suspended Solids of the effluent of wastewater treatment systems were reported as 113, 188 and 99 mg/L respectively. Comparison of the indicators between effluents of wastewater treatment systems and the standards of Departments of the Environment, showed the inefficiency in these systems and it was concluded that despite the recent improvements in hospital wastewater treatment systems, they should be upgraded based on the remarks in this paper.

  13. Immunophototherapy for the treatment of AIDS and AIDS-related infections

    Science.gov (United States)

    Schlager, Kenneth J.

    1992-06-01

    Immunophototherapy (IPT) is an experimental method of medical treatment that seeks to provide for the selective destruction of diseased cells and microbes such as human immunodeficiency virus (HIV)-T4 cells and the rapid elimination of their toxic by-products from the human body. Photosensitive monoclonal or polyclonal antibody fragments, which are specific to the diseased cell or microbe, will be used to treat acquired immunodeficiency syndrome (AIDS) and related infections. These antibody fragments are tagged with photosensitive compounds and metal colloids and then intravenously injected into the patient. The tagged antibodies quickly and selectively bind to the diseased cells or microbes in the blood stream and affected organs. These cells or microbes are then selectively destroyed by irradiation of these complexes with light of the proper wavelength. This light activates the photosensitive material which then creates singlet oxygen that destroys the microbe or cell. Toxic products of lysis are quickly discharged from the body by activation of the reticuloendothelial system. IPT has been demonstrated by Biotronics to be very effective in the in vitro selective destruction of specified cell types. In a proposed AIDS-treatment research program, IPT will be first demonstrated in vitro for a set of infected blood samples using commercially-available antibodies labeled with appropriate photosensitizers. Efficacy will be determined by a p24 antigen immunodiagnostic test that will indicate the % inhibition in comparison to controls and samples treated with the drug AZT. Subcontracted animal efficacy studies will use a SCID-hu mouse model and PCR/DNA-RNA for endpoint analysis. Toxicity studies of animal (rat) models will be based on post-treatment investigations of lymph nodes, spleen, liver and other organs.

  14. Adsorption of Roxarsone onto Drinking Water Treatment Residuals: Preliminary Studies

    2006-05-01

    Roxarsone (3-nitro-4-hydroxyphenyl-arsonic acid) is an organo-arsenical compound, commonly used as a feed additive in the broiler poultry industry to control coccidial intestinal parasites. Roxarsone is not toxic to the birds not only because of the low dose, and also because it most likely does not convert to toxic inorganic arsenic (As) in their systems. However, upon excretion, roxarsone may undergo transformation to inorganic As, posing a serious risk of contaminating the agricultural land and water bodies via surface runoff or leaching. The use of poultry litter as fertilizer results in As accumulation rates of up to 50 metric tons per year in agricultural lands. The immediate challenge, as identified by the various regulatory bodies in recent years is to develop an efficient, yet cost-effective and environmentally sound approach to cleaning up such As- contaminated soils. Recent studies conducted by our group have suggested that the drinking water treatment residuals (WTRs) can effectively retain As, thereby decreasing its mobility in the environment. The WTRs are byproducts of drinking water treatment processes and are typically composed of amorphous Fe/Al oxides, activated C and cationic polymers. They can be obtained free-of-cost from water treatment plants. It is well demonstrated that the environmental mobility of As is controlled by adsorption/desorption reactions onto mineral surfaces. Hence, knowledge of adsorption and desorption of As onto the WTRs is of environmental relevance. The reported study examined the adsorption and desorption characteristics of As using two types of WTRs, namely the Fe-WTRs (byproduct of Fe salt treatment), and the Al-WTRs (byproduct of Al salt treatment). All adsorption experiments were carried out in batch and As retention on the WTRs was investigated as a function of solid/solution ratio (1:5, 1:10, 1:25 and 1:50), equilibration time (10 min - 48 hr), pH (2 - 10) and initial As load (100, 500, 1000 and 2000 mg As/L).

It is also known to have adverse effects such as toxicity and suspected endocrine disruption. This study was carried out to study the fate of TCC in soil aquifer treatment (SAT) through laboratory simulations in a soil column. The system performance was evaluated with regards to TCC influent concentration, sand (column) depth, and residence time. Results obtained confirmed the ability of SAT to reduce TCC concentrations in wastewater. Sorption and biodegradation were responsible for TCC removal, the latter mechanism however being unsustainable. The removal efficiency was found to be dependent on concentration and decreased over time and increased with column depth. Within the duration of the experimental run, TCC negatively impacted on treatment performance through a reduction in COD removals observed in the column. © IWA Publishing 2010.

    Full Text Available AIM: Prospective observational study of symptomatic pile masses reveals that all masses in a patient may not be of the same size or degree. Since long the only treatment for different degrees of piles had been hemorrhoidectomy. Acceptance for non- surgical modalities have come up in recent past and they are being utilized because they minimize the morbidity and save working hours. Present study has successfully utilized both surgical and non -surgical methods together in a patient in the same sitting. METHODS: 102 patients with symptomatic first to third degree hemorrhoids were studied. Depending upon the degree, treatment modality was selected. Depending on the treatment given patients were divided into four groups. Sclerotherapy alone (n=25, Sclerotherapy & Band ligation (n=17, Sclerotherapy and Hemorrhoidectomy (n=24, sclerotherapy, Band Ligation & Hemorrhoidectomy (n=36. All 102 patients were subjected to four finger Lord’s Dilatation before the definitive procedures. All of them were followed for six months. Symptomatic relief, early side effects and need for re-treatment were evaluated. RESULTS: Satisfactory response was seen in 83 patients (I-20, II-13, III-20, lV-30. Sclerotherapy was more effective for 1st degree than for 2nd degree (p=0.04. Hemorrhoidectomy & band ligation were equally effective for uncomplicated 2nd degree piles. Use of hemorrhoidectomy had a definite edge in 3rd degree cases with or without associated external hemorrhoids and in 2nd degree masses with external pile mass. Local pain (no=32 and bleeding (n=6 were the most common complications. Single session was used in all the groups. None of the patients required additional treatment during follow up. Dietary modifications and life style changes were incorporated in the discharge advice for each patient. CONCLUSIONS: Conservative (non-surgical methods can be effectively used with good results even for 2nd & 3rd degree piles. Sclerotherapy & band ligation have got

    International Nuclear Information System (INIS)

    This study was performed to investigate and diagnose hydrodynamic behavior of the Military Hospital wastewater treatment plant. The plant comprises two units of treatment, each of them has a separate system. The investigation was carried out using ''1''3''1I as a radiotracer. The concept of residence time distribution (RTD) was used to investigate the efficiency of the aeration tanks, secondary clarifiers and chlorine tanks. Preliminary treatment and modeling of the trace data was performed using two software package applied by the International Atomic Energy Agency (IAEA) namely 4621 counter version 1.0.0 and RTD software. Plug flow pattern (parallel flow) was detected in the aeration tank and secondary clarifier of system 1 in one unit, while no homogeneous mixing was observed in the chlorine tank. Short - circuiting (by - passing) was evident in the aeration tank of system 2 in the other unit, which significantly reduced the operating efficiency. The percentage of dead volumes clearly suggests that the aeration tank and secondary clarifier were well utilized in the whole plant. (Author)

    The surface treatments on CdSe wafers were studied by means of SEM, XPS and micro-current test instrument. The relations between electrical properties of CdSe wafers and surface topography, composition and structure were analyzed. The results show that the change of surface composition by etching is beneficial to decrease leakage current. Meanwhile, the increase of oxygen on surface caused by passivation can largely decrease leakage current. When passivating time is 40 min, the wafers surface appears smooth and compact, which will decrease the density of surface state, the optimal electrical property of the wafer is therefore obtained.

  15. Study of ear keloid treatment in our hospital

    International Nuclear Information System (INIS)

    We studied keloid treatment in 29 patients (5 males and 24 females, 31 cases, 46 ears) with ear keloid, who attended Kansai Medical University Takii Hospital from January 2003 to March 2008. Operation was performed in 29 patients (31 cases, 46 ears), only operation in 21 cases (30 ears) and the combination of operation and irradiation in 10 cases (16 ears). Recurrence was observed in 5 cases (8 ears) without irradiation of all cases. The recurrence rate was 26.7% only in surgery and 0% in the combination. There were few rates of recurrence in the cases with local injection of steroid, triamcinolone acetonide. Allowing for the fact that the patients with ear keloid are relatively young, the recurrence rate was 26.7% only in surgery, and radiation side effects lately occurs, it is recommended that at the first time intra-keloidal excision and buried suture with polydioxanone (PDS) are performed with local pressure treatment and Tranilast medication as supplemental after cares. On the other hand, in recurrent cases after the keloid resection postoperative irradiation is adopted. (author)

    Objective To determine if postpartum antibiotics are necessary for patients with chorioamnionitis after a cesarean delivery (CD). Study Design Multicenter randomized controlled trial. Laboring patients with singleton gestations and chorioamnionitis who underwent CD were eligible. Patients were treated with ampicillin and gentamicin per standard protocol, then given clindamycin prior to skin incision. Patients were randomized to either postpartum antibiotic prophylaxis or no treatment following delivery. The primary outcome was the rate of endometritis. Assuming a 30% risk of endometritis in patients with chorioamnionitis who undergo CD, 119 patients per arm would be required to detect a 50% decrease in endometritis. Results The trial was stopped for futility following a planned interim analysis after 80 patients were randomized. There was no difference in the rate of the primary outcome between the two groups (9.8 vs. 7.7%, relative risk [RR]: 1.27; 95% confidence interval [CI]: 0.30, 5.31). A meta-analysis comparing post-CD antibiotics versus no treatment did not find a statistically significant difference between the groups (16.7 vs. 12.0%, pooled RR: 1.43; 95% CI: 0.72, 2.84). Conclusion Additional postpartum antibiotics do not decrease the rate of endometritis in patients with chorioamnionitis who undergo CD. The current preoperative antibiotic regimen including clindamycin should remain the standard of care in these patients. PMID:26890440

    2008-02-01

    The surface treatment of zinc and its corrosion inhibition was studied using a product (BTSC) formed in the reaction between benzaldehyde and thiosemicarbozide. The corrosion behaviour of chemically treated zinc surface was investigated in aqueous chloride–sulphate medium using galvanostatic polarization technique. Zinc samples treated in BTSC solution exhibited good corrosion resistance. The measured electrochemical data indicated a basic modification of the cathode reaction during corrosion of treated zinc. The corrosion protection may be explained on the basis of adsorption and formation of BTSC film on zinc surface. The film was binding strongly to the metal surface through nitrogen and sulphur atoms of the product. The formation of film on the zinc surface was established by surface analysis techniques such as scanning electron microscopy (SEM–EDS) and Fourier transform infrared spectroscopy (FTIR).

    Full Text Available Abstract Background Polypharmacy (the concurrent use of more than one psychoactive drug and other combination interventions are increasingly common for treatment of severe psychiatric problems only partly responsive to monotherapy. This practice and research on it raise scientific, clinical, and ethical issues such as additive side effects, interactions, threshold for adding second drug, appropriate target measures, and (for studies timing of randomization. One challenging area for treatment is severe child aggression. Commonly-used medications, often in combination, include psychostimulants, antipsychotics, mood stabilizers, and alpha-2 agonists, which vary considerably in terms of perceived safety and efficacy. Results In designing our NIMH-funded trial of polypharmacy, we focused attention on the added benefit of a second drug (risperidone to the effect of the first (stimulant. We selected these two drugs because their associated adverse events might neutralize each other (e.g., sleep delay and appetite decrease from stimulant versus sedation and appetite increase from antipsychotic. Moreover, there was considerable evidence of efficacy for each drug individually for the management of ADHD and child aggression. The study sample comprised children (ages 6-12 years with both diagnosed ADHD and disruptive behavior disorder (oppositional-defiant or conduct disorder accompanied by severe physical aggression. In a staged sequence, the medication with the least problematic adverse effects (stimulant was openly titrated in 3 weeks to optimal effect. Participants whose behavioral symptoms were not normalized received additional double-blind medication, either risperidone or placebo, by random assignment. Thus children whose behavioral symptoms were normalized with stimulant medication were not exposed to an antipsychotic. All families participated in an empirically-supported parent training program for disruptive behavior, so that the actual

    This paper presents completed research on the purification of undiluted raw water and organic condensates obtained in biomass thermal conversion processes such as gasification, which are rarely addressed in published studies. However, similar studies involving the characterization and purification of aqueous solutions obtained from process gas treatment after the gasification of biomass are available. Condensation of water-organic condensate from process gas helps to reduce the amount of water required by the purification process and the cost of the process technology and water consumption. Oil scrubbers can be used in this case instead of water scrubbers. In this case, the obtained condensate must be subjected to purification processes. This paper presents the results of our research, possible methods of treatment (chemical and biological methods), and the approximate cost of the reagents required for the purification of condensate for specific assumed degrees of purification. The best results from the chemical purification using the Fenton method were obtained with the ratio V(H2O2)/V(cond.) = 6.0 and the ratio V(H2O2)/Fe = 0.0375. To prevent precipitation of ferric hydroxide, this value can be reduced 20-fold, which reduces the total degree of purification to 90%. The cost of almost complete cleaning of tested condensates was calculated to be approximately 2000 USD per/m(3). This cost can be reduced by a factor of approximately four assuming 100% cleaning for 2-furaldehyde, furfuryl alcohol and phenol; acetaldehyde, propane-2-one (acetone), methanol and acetic acid are oxidized by 50%.

    Cantón, Gádor; Lasheras, Juan C.; Levy, David I.; Sparks, Steven R.

    2002-11-01

    Intracranial aneurysms are life-threatening vascular lesions, which are potentially treatable to avoid the consequences of their rupture. Current treatments, either surgical or endovascular, are all guided to reduce the hemodynamic forces acting on the aneurysm wall in an effort to minimize the risk of rupture. Surgical clipping is still the most used technique to treat this type of aneurysm but there is a continued demand for less invasive approaches. This has led to the development of several endovascular techniques. We report here a comparative study of the reduction in the hemodynamic stresses and the modification of the flow in the parent vessel resulting from the use of three different techniques. The first one consists of endosaccular packing with platinum coils (GDC, Target Therapeutics), which is already widely used but its long-term efficacy has not yet been determined. The second one consists of the embolization of the aneurismal sac with Onyx, a polymer which hardens when in contact with the blood (being developed by Micro Therapeutics, Inc.). The third one involves the packing of the sac with hydrocoils, platinum wires coated with a gel which quickly hydrates when in contact with blood (developed by MicroVention). A Digital Particle Image Velocimetry (DPIV) system is used to measure in vitro the velocity field inside a model of an ACOM aneurysm (an aneurysm forming in the anterior communicating artery). Physiological accurate pulsatile flow conditions are input to the arterial model through a programmable pump. The measurements show that although all treatment techniques lead to a reduction in both normal and tangential shear stresses on the aneurismal sac, each one of them also leads to different modifications of the flow in the parent vessel which may have consequences related to potential for clotting. Comparison of the untreated aneurysm with the above three treated cases also showed that the characteristics of the wall shear stresses on the parent

  8. Studies on the treatment of uranium mill effluents

    International Nuclear Information System (INIS)

    Overflow waters from the tailings pond in which liquid effluents in the form of barren liquors from uranium mill are discharged may contain 10 pci/litre of radium activity as against the maximum permissible discharge limit of 3 pci/litre and 10 mg/litre of soluble manganese as against the allowable limit of 0.3 mg/litre. These contaminants must be removed and/or made insoluble to ensure environmental safety. Studies were, therefore, carried out to develop methods for: (1) decontamination of both barren liquors and overflow waters and (2) their insolubilisation prior to their release in the pond. Based on the results, a scheme of treatment is formulated. Radium activity in the barren liquor is insolubilised by addition of 25 mg Ba2+/litre and precipitation. The liquor is then neutralised with lime. The sludges on liquid-solid separation are subjected to air digestion to stabilise manganese(II) to highly insoluble manganese(IV) oxide. Supernatant and the digested sludges are discharged to the tailings pond. Overflow waters from the pond are treated with 5 to 10 mgs/litre of permanganate to remove manganese and radium. The precipitates resulting in the process may be disposed as solid radioactive wastes and decontaminated water may be released to the environment or if it meets the mill specification, may be reused as process water thus ruling out even the slightest possibility of environmental pollution. The overall cost of chemicals required for the treatment mentioned above works out to be Rs. 0.30 per cubic metre of effluent. (M.G.B.)

Diode laser is a useful device for DH treatment if used alone and mainly if used with NaF gel.

  12. Photoneutron source for in-hospital BNCT treatment. Feasibility study

    International Nuclear Information System (INIS)

    Some recent studies in Italy have focused on the possibility of exploiting high energy electron linear accelerators, normally used in gamma radiotherapy, as photo-neutrons source for in-hospital medical applications. Neutrons are produced by Giant Dipole Resonance (GDR) reactions from high energy photons on high Z targets; by proper material and geometry optimization, interesting fluence rates of thermalized neutrons can be made available, with minimized fast neutron and gamma backgrounds, for a fractionated type of Boron Neutron Capture Therapy (BNCT) devoted to external treatment of some specific tumors. A photoneutron converter, constituted by high Z core and surrounded by Low Z materials, is shaped to produce thermal beam inside an irradiation cavity. A feasibility study on Beam Shaping Assembly using MCNPGN simulation code is performed on various geometrical shapes and material selection. A first prototype of the photoconverter has been realized and tested at some hospital high energy medical LINAC facilities. In this paper the preliminary experimental results of neutron fluence rate and neutron spectra produced by the photoconverter prototype are compared to the simulation data. (author)

  13. A study on the safety of tritium storage and treatment

    International Nuclear Information System (INIS)

    For reduction of tritium release to the environment and utilization of tritium at industrial application and fusion technology, it is necessary to separate and store tritium. As a tritium separation and storage system, Tritium Removal Facility (TRF) and tritium storage vessel is under development in Korea. For the construction and operation of the system, it is necessary to estimate the safety of tritium storage system. As an isotope of hydrogen, tritium has similar hazards to hydrogen. In addition to the hydrogen hazards, due to radioactive decay of tritium, it is necessary to consider the risk of hydrogen and radioactive decay for the safe storage. In this study, hazards of hydrogen and the risk due to storage of tritium are reviewed. The safety related factors are suggested in terms of classification of hydrogen hazards and problems related to the tritium storage. The major design parameters of the vessel of foreign countries for the storage and transport of tritium are reviewed. By review of major safety parameters related to the tritium storage, the results of this study can be applied and helpful to the development and design of tritium storage vessel in Korea. Also, the results can be useful at design of the tritium treatment facility

    Mullen, Louise

    2012-07-02

    Background: Retention in treatment is a key indicator of methadone treatment success. The study aims to identify factors that are associated with retention. Objectives: To determine retention in treatment at 12 months for Irish opiate users in methadone substitution treatment and to indicate factors that increase the likelihood of retention. Methods: National cohort study of randomly selected opiate users commencing methadone treatment in 1999, 2001, and 2003 (n = 1269). Results: Sixty-one percent of patients attending methadone treatment remained in continuous treatment for more than 1 year. Retention in treatment at 12 months was associated with age, gender, facility type, and methadone dose. Age and gender were no longer significant when adjusted for other variables in the model. Those who attended a specialist site were twice as likely to leave methadone treatment within 12 months compared with those who attended a primary care physician. The most important predictor of retention in treatment was methadone dose. Those who received <60 mg of methadone were three times more likely to leave treatment. Conclusion: Retention in methadone treatment is high in Ireland in a variety of settings. The main factors influencing retention in methadone treatment was an adequate methadone dose and access to a range of treatment settings including from primary care physicians. Scientific Significance: Providing an adequate dose of methadone during treatment will increase the likelihood of treatment retention. Methadone treatment by the primary care physician is a successful method of retaining opioid users in treatment.

    2016-06-01

    A novel bioaugmentation treatment approach, the Small-Bioreactor Platform (SBP) technology, was developed to increase the biological stabilization process in the treatment of wastewater in order to improve wastewater processing effectiveness. The SBP microfiltration membrane provides protection against the natural selection forces that target exogenous bacterial cultures within wastewater. As a result, the exogenous microorganisms culture adapt and proliferate, thus providing a successful bioaugmentation process in wastewater treatment. The new bioaugmentation treatment approach was studied in a full configuration Membrane Bioreactor (MBR) plant treating domestic wastewater. Our results present the potential of this innovative technology to eliminate, or reduce, the intensity of stress events, as well as shortening the recovery time after stress events, consequently elevating the treatment effectiveness. The effective dose of SBP capsules per cubic metre per day of wastewater was achieved during the addition of 3000 SBP capsules (1.25 SBP capsules per cubic metre per day), which provided approximately 4.5 L of high concentration exogenous biomass culture within the SBP capsules internal medium. This study demonstrates an innovative treatment capability which provides an effective bioaugmentation treatment in an MBR domestic wastewater treatment plant. PMID:26581124

  20. Technology transfer for Ukrainian milk treatment: A case study

    International Nuclear Information System (INIS)

    As a result of the Chernobyl Nuclear Power Plant accident, radioactive fission products have contaminated the food chain in the Ukraine. The highest doses to humans are a result of cesium contamination in milk. The milk produced in the Ukraine contains radioactive cesium at levels up to 10 times the acceptance standards. Bradtec has developed and demonstrated technology for the US Department of Energy for the treatment of groundwater and effluent water. This technology has also been tested and demonstrated for the Ukrainian government for the purpose of treating contaminated milk. Bradtec, a small business offering specialized technologies in the field of environmental remediation and waste management, has successfully worked with a consortium of businesses, National Laboratories and DOE Headquarters staff to develop and implement a technology demonstration strategy which has led to the implementation of a series collaboration agreements with Ukrainian officials. This paper describes, in a case study approach, the path followed by Bradtec and its collaboration partners in successfully implementing a technology transfer strategy. Also presented is an update on new programs that can provide benefit to private sector companies as DOE seeks to assist the private sector in joint venture/technology transfer relationships with the NIS (New Independent States). This paper should be of interest to all businesses seeking to participate in business opportunities in the NIS

  1. Studies of testicular function after treatment for testicular tumor, 2

    International Nuclear Information System (INIS)

    It is important to preserve the testicular function of patients with testicular tumor after treatment. Testicular function after radiotherapy was endocrinologically investigated in the present study. 1. The levels of LH, FSH and testosterone in the blood were sequentially determined in patients with testicular tumor before, during and after radiotherapy. The blood levels of LH and FSH were high after therapy in the majority of the cases, but the levels decrease concomitantly with time. Blood levels of testosterone remained within the normal range. 2. The Gn-RH stimulation test after radiotherapy revealed an abnormally high response and a delayed normalization of the LH level within three years after therapy. However, these changes showed a tendancy to normalize in the patients after therapy for three years or longer. 3. The hCG stimulation test was performed after radiotherapy. The reaction rate of hCG was low in patients within three years on therapy, whereas it tended to return to normal pattern after three or more years on therapy. The results lead the conclusion as follows. 1. Spermatogenesis was damaged in the majority of testicular tumor after radiotherapy. However, it was recovered to a normal spermatogenesis after cessation of the therapy. 2. From the high basal level of serum LH and the response to Gn-RH and hCG stimulation tests after radiotherapy, it is presumed that the reserve function of Leydig cell was impaired by radiotherapy, although it returns to normal status after three years on the therapy.

    Tang, Yik Sau; Lai, Siu Kai; Cheng, Stephen Wing Keung; Chow, Kwok Wing

    2012-11-01

    Thoracic Aortic Dissection (TAD), a life threatening cardiovascular disease, occurs when blood intrudes into the layers of the aortic wall, creating a new artificial channel (the false lumen) beside the original true lumen. The weakened false lumen wall may expand, enhancing the risk of rupture and resulting in high mortality. Endovascular treatment involves the deployment of a stent graft into the aorta, thus blocking blood from entering the false lumen. Due to the irregular geometry of the aorta, the stent graft, however, may fail to conform to the vessel curvature, and would create a ``bird-beak'' configuration, a wedge-shaped domain between the graft and the vessel wall. Computational fluid dynamics analysis is employed to study the hemodynamics of this pathological condition. With the `beaking' configuration, the local hemodynamic shear stress will drop below the threshold of safety reported earlier in the literature. The oscillating behavior of the shear stress might lead to local inflammation, atherosclerosis and other undesirable consequences.

    International Nuclear Information System (INIS)

    The effects of 60Co gamma rays on pork Trichinella spiralis and nutritional hygiene evaluation of irradiated Trichinella spiralis pork were studied by using animal infestation test and artificial gastric juice digestion method. The results showed that when mouse was infested by Trichinella spiralis pork irradiated with a dose of 0.04 kGy, the number of the second generation larvae and the parasitism in the muscle were reduced. 0.08 kGy irradiation could render the intestine Trichinella spiralis sterile. 0.1 kGy blocked the growth of Trichinella spiralis, which were excreted from the body four days after infestation. 0.2-0.8 kGy irradiation could severely block the growth of Trichinella spiralis, which were excreted completely from the body within forth-eight hours when irradiated with 7 kGy and 8 kGy, the Trichinella spiralis body was not found in the intestine within twenty-four hours. 0.3 kGy and 1 kGy irradiation had no harmful effect on nutrition and wholesomeness of Trichinella spiralis pork. Innocent irradiation treatment of Trichinella spiralis pork is practicable, and the lowest dose should be 0.3 kGy

    2012-01-01

    In addition to the nucleoside reverse transcriptase inhibitors (NRTIs), protease inhibitors (PIs) and integrase inhibitors (INIs), nonnucleoside reverse transcriptase inhibitors (NNRTIs) have contributed significantly in the treatment of HIV-1 infections. More than 60 structurally different classes of compounds have been identified as NNRTIs, which are specifically inhibiting HIV-1 reverse transcriptase (RT). Five NNRTIs (nevirapine, delavirdine, efavirenz, etravirine and rilpivirine) have been approved by US Food and Drug Administration (FDA) for clinical use. The NNRTIs bind with a specific 'pocket' site of HIV-1 RT (allosteric site) that is closely associated with the NRTI binding site. Due to mutations of the amino acid residues surrounding the NNRTI-binding site, NNRTIs are notorious for rapidly eliciting resistance. Though, the emergence of resistant HIV strains can be circumvented if the NNRTIs are used either alone or in combination with NRTIs (AZT, 3TC, ddI, ddC, TVD or d4T) and PIs (Indinavir, nelfinavir, saquinavir, ritonavir and lopinavir etc.) as shown by both a decrease in plasma HIV-1 RNA levels and increased CD4 T-cells. Here we are going to discuss recent advances in structure activity relationship studies on nevirapine, delavirdine, efavirenz, etravirine, rilpivirine and 4-thiazolidinones (privileged scaffold) HIV-1 NNRTIs.

    van der Meer Sanchez, Zila; Nappo, Solange A

    2008-08-01

    The main objective of the present work is to understand the processes used in emerging Catholic and Protestant religious interventions for recovery from drug dependence, from the vantage point of individuals subjected to them. A qualitative method and an intentional sample selected by criteria were adopted for this investigation, which was conducted in São Paulo, Brazil. An in-depth semi-structured interview was conducted with 57 predominantly male former drug users who fit the criteria: they had been submitted to non-medical religious treatments to treat dependence and were abstinent for at least 6 months. Crisis was found to be the main reason leading interviewees to seek treatment; this includes, losing family, losing employment, and experiencing severe humiliation. Evangelicals most used religious resources exclusively as treatment, showing strong aversion to the role of doctors and to any type of pharmacological treatment. A common feature of Catholic and Protestant groups is the importance ascribed to praying and talking to God, described by subjects as strongly anxiolytic, and a means to control drug craving. Confession and forgiveness, through faith conversion or penitences, respectively, appeal strongly to the restructuring of life and increase of self-esteem. Religious interventions were considered effective by the individuals who underwent them and were seen as attractive for the humane, respectful treatment they delivered. The key aspects of this type of treatment are social support provided by the receiving group, equal treatment, and instant, judgment-free acceptance. The success of these actions, then, is not only due to some "supernatural" aspect, as might be assumed, but also more to the unconditional dedication of human beings to their peers. Given the difficulty in treating drug dependence, religious interventions could be used as a complementary treatment for conventional therapies. PMID:18501491

  14. Treatment planning for Hodgkin's Disease: a patterns of care study

    International Nuclear Information System (INIS)

    Purpose: To conduct a survey of the process of treatment planning for the radiation treatment of Hodgkin's Disease in the United States, and to compare survey results with consensus guidelines as determined by recognized experts. Methods and Materials: A consensus committee developed guidelines for the radiotherapeutic management of Hodgkin's Disease. A series of survey forms were designed to evaluate the standards of practice and compare these with the consensus guidelines. A total of 61 facilities divided evenly into the strata of academic, hospital based, and free standing had eligible Hodgkin's Disease cases. There were 275 eligible cases of Hodgkin's Disease evaluated. Data collected from the radiation oncology records included treatment-specific parameters such as energy, dose, blocking, and calculations, as well as treatment planning practices. Statistical analysis was performed on each data element and for all institution strata. Results: For a number of treatment parameters, there were some discrepancies noted between the current United States practice and the consensus guidelines. Some significant differences were found in practice between the stratified institution types. A representative sample of results are: the majority of Hodgkin's Disease patients are treated with x-ray energies in the recommended range, between 4 and 10 MV. Standard mantle (for upper extended field treatment) and modified spade (for lower extended field treatments) are the fields of choice for all types of facilities. The consensus guidelines recommended that dose calculations at multiple points be obtained; however, 15% of patients in the survey received only a single point calculation. Current irregular field dosimetry calculation software does not take account of inhomogeneities.

DeGroote School of Medicine, McMaster University, 9Biostatistics Unit, Centre for Evaluation of Medicine, 10System Linked Research Unit, 11Department of Pathology and Molecular Medicine, McMaster University, Hamilton, Ontario, Canada Introduction: Treatment of opioid addiction with methadone is effective; however, it is known to produce interindividual variability. This may be influenced in part by genetic variants, which can increase the initial risk of developing opioid addiction as well as explain differences in response to treatment. This pilot study aimed to assess the feasibility of conducting a full-scale genetic analysis to identify genes that predict methadone treatment outcomes in this population. Methods: This was a cross-sectional observational study of patients admitted to a methadone maintenance treatment program for opioid addiction. We obtained demographic and clinical characteristics in addition to blood and urine samples, for the assessment of treatment outcomes. Results: The recruitment process yielded 252 patients, representing a 20% recruitment rate. We conducted genetic testing based on a 99.6% rate of provision of DNA samples. The average retention in treatment was 3.4 years, and >50% of the participants reported psychiatric and

    2004-07-01

    The purpose of this document is to discuss issues related to the implementation of each of the five down-selected INEEL/INTEC radioactive liquid waste (sodium-bearing waste - SBW) treatment alternatives and summarize information in three main areas of concern: process/technical, environmental permitting, and schedule. Major implementation options for each treatment alternative are also identified and briefly discussed. This report may touch upon, but purposely does not address in detail, issues that are programmatic in nature. Examples of these include how the SBW will be classified with respect to the Nuclear Waste Policy Act (NWPA), status of Waste Isolation Pilot Plant (WIPP) permits and waste storage availability, available funding for implementation, stakeholder issues, and State of Idaho Settlement Agreement milestones. It is assumed in this report that the SBW would be classified as a transuranic (TRU) waste suitable for disposal at WIPP, located in New Mexico, after appropriate treatment to meet transportation requirements and waste acceptance criteria (WAC).

    Morgellons Disease is a condition involving painful skin lesions, fibrous growths protruding from the skin, and subcutaneous stinging and burning sensations, along with symptoms of anxiety, depression, fatigue, and memory and attention deficits. The etiological and physiological bases of these symptoms are unclear, making the diagnosis controversial and challenging to treat. There are currently no established treatments for Morgellons Disease. The following case example depicts treatment of a woman with Morgellons Disease using hypnotherapy. Data from this case example suggest that hypnotherapy is a promising intervention for the physical and psychological symptoms associated with Morgellons Disease. PMID:21390982

    The mechanism of industrial wastewater treatment using superconducting magnetic separation is investigated. Fe 3O 4 nanoparticles were prepared by liquid precipitation and characterized by X-ray diffraction (XRD). Polyacrylic acid (PAA) film was coated on the magnetic particles using plasma coating technique. Transmission electron microscope (TEM) observation and infrared spectrum measurement indicate that the particle surface is well coated with PAA, and the film thickness is around 1 nm. Practical paper factory wastewater treatment using the modified magnetic seeds in a superconducting magnet (SCM) was carried out. The results show that the maximum removal rate of chemical oxygen demand (COD) by SCM method can reach 76%.

    The records of 142 patients with generalized autoimmune myasthenia gravis who had been treated with steroids as the single immunosuppressive agent, collected at regular intervals, were employed for a retrospective evaluation. The effectiveness of treatment was assessed after 24 months; the data from the 6th and 12th months were also considered. After 24 months, 63.4% of the whole sample had improved (33.8% were in clinical or pharmacological remission); 13.4% were unchanged or had worsened and 22.3% had moved to a different immunosuppressive treatment. The rate of positive outcome was higher in patients over the age of 40 at disease onset. PMID:1927259

  4. Time to treatment as a quality metric in lung cancer: Staging studies, time to treatment, and patient survival

    International Nuclear Information System (INIS)

    Purpose: Prompt staging and treatment are crucial for non-small cell lung cancer (NSCLC). We determined if predictors of treatment delay after diagnosis were associated with prognosis. Materials and methods: Medicare claims from 28,732 patients diagnosed with NSCLC in 2004–2007 were used to establish the diagnosis-to-treatment interval (ideally ⩽35 days) and identify staging studies during that interval. Factors associated with delay were identified with multivariate logistic regression, and associations between delay and survival by stage were tested with Cox proportional hazard regression. Results: Median diagnosis-to-treatment interval was 27 days. Receipt of PET was associated with delays (57.4% of patients with PET delayed [n = 6646/11,583] versus 22.8% of those without [n = 3908/17,149]; adjusted OR = 4.48, 95% CI 4.23–4.74, p < 0.001). Median diagnosis-to-PET interval was 15 days; PET-to-clinic, 5 days; and clinic-to-treatment, 12 days. Diagnosis-to-treatment intervals <35 days were associated with improved survival for patients with localized disease and those with distant disease surviving ⩾1 year but not for patients with distant disease surviving <1 year. Conclusion: Delays between diagnosing and treating NSCLC are common and associated with use of PET for staging. Reducing time to treatment may improve survival for patients with manageable disease at diagnosis

  5. Treatment manuals and the advancement of psychoanalytic knowledge: The Treatment Manual of the Tavistock Adult Depression Study.

    Science.gov (United States)

    Taylor, David

    2015-06-01

    This paper has two aims: first, it seeks to understand the absence of treatment manuals in psychoanalysis. Secondly, it summarizes the treatment manual of the Tavistock Adult Depression Study, which describes the form of psychoanalytic psychotherapy whose effectiveness has been evaluated both in the Tavistock Adult Depression Study (TADS); and in the German Die Langzeittherapie bei chronischen Depressionen (LAC) Studie. Throughout the history of psychoanalysis, opinions about treatment manuals, empirical research and their antecedents have been deeply divided. After tracing the often polarized unfolding of these matters, the paper proposes that emotional and cognitive difficulties as well as scientific ones underpin their persistence. It is suggested that greater familiarity with them may lead to better combinations of outcome research and psychoanalysis: for example, the Tavistock manual seeks to match one account of the objects, aims, values, spirit and methods of psychoanalysis (as well as of connected forms of psychoanalytic psychotherapy); and also to meet what is required of treatment manuals by random allocation controlled trials. It has been a crucial element in the above studies of the outcome of long-term psychoanalytic psychotherapies with chronically depressed patients. After describing the Tavistock Manual, the paper concludes suggesting that, if appropriately constructed, treatment manuals can make a contribution to the advancement of specifically psychoanalytic knowledge.

    2009-01-01

    The opening of the deepest undersea tunnel in the world (264 m below sea level, 5600 m in length) replaced the ferry from the island of Hitra to the mainland in Norway. This event provoked phobic anxiety for traveling through the undersea tunnel in a number of individuals in the area. A treatment program for tunnel phobia was designed to test whether such a phobia could be mitigated by procedures previously proven effective in the treatment of other phobias. The program was presented to 18 persons with a specific phobia for tunnels and included a general discussion on the construction of undersea tunnels, given by an engineer from the tunnel construction company, and on phobic anxiety. It further consisted of gradual exposure to the tunnel in situ. Treatment effects were strong. All patients were able to travel on their own by car through the tunnel after the treatment. Their somatic complaints and phobic thoughts related to the tunnel were substantially reduced, and their mastery of tunnel driving was convincingly increased compared with the wait-list reference group.

  12. Studies on treatment of radioactive animal carcass, (1)

    International Nuclear Information System (INIS)

    A new method of waste treatment of animal carcass contaminated with plutonium was proposed. A multi-step process was designed and tested at a laboratory scale which was composed of the following processes; microwave dehydration, heat decomposition and ashing. Microwave dehydration was found the most adequate as the first step of the treatment because of the negligible release of nonvolatile radioactivity. About 70% of body weight was reduced by microwave dehydration. Dehydrated animal carcass was decomposed by graded electric heating under anaerobic condition. Burnable gas and vapour produced by the heat decomposition were oxidized by passing through a reheating tube with excess air. The exhaust gas had no significant radioactivity. The residue of charred carcass was oxidized by heating with excess air. The weight of final product was up to 8% of original wet weight. The proposed multi-step process provided to be adequate for the waste disporsal of Pu contaminated animal carcass. (author)

    1997-07-01

    This review addresses several issues, such as possible advantages of light ion therapy compared to protons and conventional radiation, the complexity of such a system and its possible adaptation to a hospital environment, and the question of cost-effectiveness compared to other modalities for cancer treatment or to other life saving procedures. Characteristics and effects of different types of radiation on cells and organisms will be briefly described; this will include conventional radiation, protons and light ions. The status of proton and light ion cancer therapy will then be described, with more emphasis on the latter; on the basis of existing experience the criteria for the use of light ions will be listed and areas of possible medical applications suggested. Requirements and parameters of ion beams for cancer treatment will then be defined, including ion species, energy and intensity, as well as parameters of the beam when delivered to the target (scanning, time structure, energy spread). Possible accelerator designs for light ions will be considered, including linear accelerators, cyclotrons and synchrotrons and their basic features given; this will be followed by a review of existing and planned facilities for light ions. On the basis of these considerations a tentative design for a dedicated light ion facility will be suggested, a facility that would be hospital based, satisfying the clinical requirements, simple to operate and reliable, concluding with its cost-effectiveness in comparison with other modalities for treatment of cancer.

    With the view to finding a more effective and economic system for the disposal of hospital sewage, a series of experimental and on the spot investigations were conducted. The results are as follows. Disinfection must be taken as the key link in the treatment of hospital sewage. After primary treatment and chlorination, when the product value of concentration (mg/L) multiplied by time (min.) achieved to 240 (general hospital) and 540 (tuberculosis hospital), the content of suspended substances (SS) fell to 37 mg/L; the clearance rate of SS reached 82%. The BOD5 fell to 35 mg/L a drop to 42%. E. coli was less than 9 individual/L, the killing rate reached 99.999 99%. The intestinal pathogens and tubercle bacillus were completely wiped out. The sludge from the sewage can be treated with lime [Ca(OH)2] and when the pH value rose to 12, the requirement of disinfection was satisfied and both the sludge and sewage can be drained. The aeration of sewage through shooting flow, biological oxidation combined with sediment action by passing thru reclining tubes is an effective way for the secondary treatment of hospital sewage. In addition, we developed the double siphon equipment with water power-automatic controller, the WD-700 flowmeter, the anti-corrosive paint coating the contact pond; according to test parameters, we designed a simplified evaluation graph for the purpose of surveillance.

    Nowadays, the cellulosic ethanol is an important alternative way to many liquid biofuels using renewable biomass rich in polysaccharides. To be used as feedstock for ethanol production, the bagasse needs to be pretreated in order to expose its main constitutive. The present work proposes the use of different pretreatment processes to better expose the cellulose for hydrolysis and fermentation. In the present paper the sugarcane bagasse was submitted to a hydrothermal pretreatment followed by atmospheric pressure plasmas (APPs). An RF microplasma torch was employed as APPs in Ar and Ar/O2 mixing. The bagasse was treated in discharge and post-discharge regions. The position and time of treatment was varied as well as the gas mixture. The quantity of polysaccharides was determined by using high performance liquid chromatography. It was observed the release of a fraction of the hemicelluloses in the sugarcane bagasse. Modifications in the surface of the sugarcane fibers were monitored by employing scanning electron microscopy.

STUDY DESIGN : Patients presenting to our hospital from the period March’ 2014 to December’ 2014 with venous ulcers were examined and investigated. Thirty patients who had findings of venous ulcers along with varicose veins were selected for the study. Patients were initially treated with elastic compression bandages to allow ulcer healing followed by surgical intervention of varicose veins and incompetent perforators. The response to treatment was evaluated in terms of symptomatic improvement and ulcer healing. RESULTS: Venous ulcers respond well to both conservative treatment and surgical intervention. Meticulous assessment of patients is necessary for successful treatment. In our study period, elastic compres sion bandages combined with surgical treatment was successful in improving symptoms of venous ulcer as well as ulcer healing in the patients. Patient education regarding compliance to treatment is paramount to ulcer healing and preventing recurrence.

  6. Experimental study for cancer treatment using synchrotron radiation

    International Nuclear Information System (INIS)

    Radiotherapy is one of the most powerful treatments for brain tumor. Penetrating ionizing particles is aimed toward the tumor, delivering as high radiation to it as is usefully suppressive of tumor growth, and tolerated by normal vital tissues inevitably irradiated with the tumor. The use of a high-energy synchrotron-radiation thin X-ray beams (microplanar beams, or microbeams) produced through a multi-slit collimator has been reported to enhance the tolerance of normal tissue to radiation. The high collimation and dose rate of synchrotron X-ray beams favor radiotherapy. Irradiation with parallel arrays of microbeam, planar slices of spares normal brain, and preferentially damages tumors. The width of the peak region was 20-25 μm, and the spacing between the regions was 100-300 μm. We firstly examined the dose distribution with micro-scale resolution in order to clarify this phenomenon. Secondary, radiotherapy of malignant brain tumors in rats was performed. The treatment results in extended median survival time. The effects are mediated, at least in part, by the tissue's microvasculature that seems to effectively repair itself in normal brain but fails to do so in tumors. (author)

    Purpose: To determine the best treatment technique for patients with retinoblastoma requiring radiotherapy to the whole eye. Methods and Materials: Treatment plans for 3 patients with retinoblastoma were developed using 10 radiotherapy techniques including electron beams, photon beam wedge pair (WP), photon beam three-dimensional conformal radiotherapy (3D-CRT), fixed gantry intensity-modulated radiotherapy (IMRT), photon volumetric arc therapy (VMAT), fractionated stereotactic radiotherapy, and helical tomotherapy (HT). Dose-volume analyses were carried out for each technique. Results: All techniques provided similar target coverage; conformity was highest for VMAT, nine-field (9F) IMRT, and HT (conformity index [CI] = 1.3) and lowest for the WP and two electron techniques (CI = 1.8). The electron techniques had the highest planning target volume dose gradient (131% of maximum dose received [D{sub max}]), and the CRT techniques had the lowest (103% D{sub max}) gradient. The volume receiving at least 20 Gy (V{sub 20Gy}) for the ipsilateral bony orbit was lowest for the VMAT and HT techniques (56%) and highest for the CRT techniques (90%). Generally, the electron beam techniques were superior in terms of brain sparing and delivered approximately one-third of the integral dose of the photon techniques. Conclusions: Inverse planned image-guided radiotherapy delivered using HT or VMAT gives better conformity index, improved orbital bone and brain sparing, and a lower integral dose than other techniques.

Methods and Materials: Treatment plans for 3 patients with retinoblastoma were developed using 10 radiotherapy techniques including electron beams, photon beam wedge pair (WP), photon beam three-dimensional conformal radiotherapy (3D-CRT), fixed gantry intensity-modulated radiotherapy (IMRT), photon volumetric arc therapy (VMAT), fractionated stereotactic radiotherapy, and helical tomotherapy (HT). Dose-volume analyses were carried out for each technique. Results: All techniques provided similar target coverage; conformity was highest for VMAT, nine-field (9F) IMRT, and HT (conformity index [CI] = 1.3) and lowest for the WP and two electron techniques (CI = 1.8). The electron techniques had the highest planning target volume dose gradient (131% of maximum dose received [Dmax]), and the CRT techniques had the lowest (103% Dmax) gradient. The volume receiving at least 20 Gy (V20Gy) for the ipsilateral bony orbit was lowest for the VMAT and HT techniques (56%) and highest for the CRT techniques (90%). Generally, the electron beam techniques were superior in terms of brain sparing and delivered approximately one-third of the integral dose of the photon techniques. Conclusions: Inverse planned image-guided radiotherapy delivered using HT or VMAT gives better conformity index, improved orbital bone and brain sparing, and a lower integral dose than other techniques.

    Full Text Available The characteristics of the greywater vary from country to country and it depends upon the cultural and social behavior of the respective country. There was a considerable need to characterize and recycle the greywater. In this regard greywater was separated from the black water and analyzed for various physiochemical parameters. Among various greywater recycling treatment technologies, RBC (Rotating Biological Contactor is more effective treatment technique in reducing COD (Chemical Oxygen Demand and organic matters from the greywater. But this technology was not applied and tested in Pakistan. There was extensive need to investigate the RBC technology for greywater recycling at small scale before applying at mass scale. To treat the greywater, a single-stage RBC simulator was designed and developed at laboratory scale. An electric motor equipped with gear box to control the rotations of the disks was mounted on the tank. The simulator was run at the rate of 1.7 rpm. The disc area of the RBC was immersed about 40% in the greywater. Water samples were collected at each HRT (Hydraulic Retention Time and analyzed for the parameters such as pH, conductivity, TDS (Total Dissolved Solids, salinity, BOD5 (Biochemical Oxygen Demand, COD and suspended solids by using standard methods. The results are encouraging with percentage removal of BOD5 and COD being 53 and 60% respectively.

  10. TREATMENT TANK CORROSION STUDIES FOR THE ENHANCED CHEMICAL CLEANING PROCESS

    Radioactive waste is stored in high level waste tanks on the Savannah River Site (SRS). Savannah River Remediation (SRR) is aggressively seeking to close the non-compliant Type I and II waste tanks. The removal of sludge (i.e., metal oxide) heels from the tank is the final stage in the waste removal process. The Enhanced Chemical Cleaning (ECC) process is being developed and investigated by SRR to aid in Savannah River Site (SRS) High-Level Waste (HLW) as an option for sludge heel removal. Corrosion rate data for carbon steel exposed to the ECC treatment tank environment was obtained to evaluate the degree of corrosion that occurs. These tests were also designed to determine the effect of various environmental variables such as temperature, agitation and sludge slurry type on the corrosion behavior of carbon steel. Coupon tests were performed to estimate the corrosion rate during the ECC process, as well as determine any susceptibility to localized corrosion. Electrochemical studies were performed to develop a better understanding of the corrosion mechanism. The tests were performed in 1 wt.% and 2.5 wt.% oxalic acid with HM and PUREX sludge simulants. The following results and conclusions were made based on this testing: (1) In 1 wt.% oxalic acid with a sludge simulant, carbon steel corroded at a rate of less than 25 mpy within the temperature and agitation levels of the test. No susceptibility to localized corrosion was observed. (2) In 2.5 wt.% oxalic acid with a sludge simulant, the carbon steel corrosion rates ranged between 15 and 88 mpy. The most severe corrosion was observed at 75 C in the HM/2.5 wt.% oxalic acid simulant. Pitting and general corrosion increased with the agitation level at this condition. No pitting and lower general corrosion rates were observed with the PUREX/2.5 wt.% oxalic acid simulant. The electrochemical and coupon tests both indicated that carbon steel is more susceptible to localized corrosion in the HM/oxalic acid environment than

    This paper describes a case of a patient (GX) with a brain tumour in the third ventricle who developed a syndrome of amnestic disorder and vegetative abnormalities (hyperphagia, oligodipsia) after irradiation treatment that followed brain surgery. The patient shows an extremely poor long-term memory on both visually and verbally presented material, and of autobiographical events occurring after the onset of the illness, but some preserved memory functions on short-term memory tasks, semantic memory tasks, and implicit memory tasks. Given the onset of symptoms only after irradiation (a memory deficit in particular), and the non-invasive nature of the surgery, the probable etiology is post-irradiation syndrome. (au) (27 refs.).

    Smith, Brenda D; Manfredo, Irene T

    2011-09-01

    This study addresses the challenge of implementing evidence-based treatment approaches in typical community settings. It identifies individual and organizational characteristics associated with two contrasting treatment approaches used by frontline practitioners. One treatment approach involves techniques supported by research; the other approach involves techniques primarily supported by experience and tradition. The study uses a nested probability sample of 45 organizations and 279 frontline practitioners. Multilevel (hierarchical linear modeling) regression models appropriately address the nested sample. The findings indicate that practitioner beliefs and components of organizational social contexts are associated with treatment approach. The use of an evidence-supported treatment approach is associated with opportunities to use training and with transformational leadership. A traditional treatment approach is more commonly used when practitioners have more positive perceptions of the organizational climate. The findings underscore the challenge of implementing evidence-based treatment techniques among counselors committed to traditional approaches. PMID:21632198

    This article indicates the origins and background of the current series of National Institute of Dental and Craniofacial Research-funded, university-based clinical studies of orthodontic treatment. It suggests that future studies should be less focused on refining our estimates of mean changes during treatment and concentrate research on the systematic analysis of individual differences among patients' responses to treatment, and study how skilled clinicians make in-course corrections in response to unexpected changes in treatment conditions. Finally, some suggestions are made concerning optimization of decision making in the presence of uncertainty. PMID:10530283

  20. Psychogenic seizures in brain injury: diagnosis, treatment and case study.

    Science.gov (United States)

    Conder, R L; Zasler, N D

    1990-01-01

    Psychogenic seizures are a functional phenomena in which a person experiences a paroxysmal event that may be interpreted as epileptiform in nature. By definition, psychogenic seizures imply a sudden episode of change in behaviour or psychic state that is not associated with an identifiable process, either vasculogenic or neurogenic, and during which there is an absence of characteristic epileptiform changes on the electroencephalogram. Prevalence rates range from 5% to 50% in outpatient populations seen in epilepsy clinics. However, approximately 20% of true seizure patients also have psychogenic seizures. As psychogenic seizures are not a pathophysiological phenomena, pharmacological interventions do not alter their aetiology and can cloud the cognitive skills necessary to ameliorate the psychogenic seizure behaviour. In non-aphasic true seizure patients, as well as psychogenic seizure patients, self-control relaxation paradigms have been successful where pharmacological intervention has failed. This case involved an aphasic brain-injured patient who had both psychogenic and true seizures. For this patient, the self-control paradigm was modified to include use of gesture and prosody to achieve similar psychotherapeutic effects. Additionally, family therapy was instituted to provide a constructive means for the patient's family to participate in the reduction of psychogenic seizures. As seizures are a common sequelae of brain injury, the differential diagnosis of seizures and knowledge of standard and alternative treatment is essential for rehabilitation professionals.

  1. Study of Thermal Treatment on Properties of Polycrystalline Silicon

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    The effects of thermal annealing on oxygen behavior and carrier lifetimes of mc-Si wafers were investigated by means of FTIR and QSSPCD during single step and two step heat treatments in N2 and O2 ambient. It reveals that interstitial oxygen concentration of mc-Si and CZ-Si has a slighter decrease in N2 and O2 ambient during single-step annealing, which means oxygen precipitates are not generated. But oxygen concentration greatly decreases and generates a number of oxygen precipitates during two-step annealing. Bulk lifetime of mc-Si increases in N2 ambient at 850, 950, 1150 ℃ respectively, and annealing in O2 shows better results than that in N2 and annealing in two-step reflected better consequence than annealing in single-step. But lifetime of CZ-Si annealed in N2 or O2 decreases rapidly. The reason of lifetime increase is probably considered due to the fact that interstitial Si atoms of Si/SiO2 interface fill vacancies or some recombination centers at high temperature annealing. Moreover, a number of impurities in mc-Si probably diffuse to grain boundaries so that greatly reduce recombination centers result to lifetime rising.

  2. Studies on treatment of radioactive animal carcass, (2)

    International Nuclear Information System (INIS)

    A method of dehydration for the waste treatment of radioactive animal carcass by microwave heating was developed. A heating apparatus was devised by annexing the microwave output controlling circuit to a 600 W commercial microwave oven, and the aqueous vapour from the animal carcass was collected by duplex cold traps. Body weight of the carcass was reduced to 20-30% by dehydration, and a three-year storage test proved that the dehydrated carcass was very hard to decompose. Time needed for dehydration was about 10 min for a 25 g mouse, and about 1 hr for 668 g dog. Violent rupture of the carcass, and/or fuming due to overheating that had often been observed during dehydration were proved to be avoidable by controlling the microwave output during the process. The ratio of radioactivity (60Co, 137Cs, 85Sr, 144Ce) that escaped from the carcass during dehydration was found to be less than 3 x 10-4 by a series of experiment. Some related radiation safety problems were discussed. (author)

  3. Advanced supraglottic carcinoma: a comparative study of sequential treatment policies

    International Nuclear Information System (INIS)

    Data from 131 consecutive patients with operable stage III or IV (American Joint Committee) supraglottic carcinoma were analyzed. Based on existing treatment policies at the time of presentation, patients received either preoperative radiation therapy (RT) (48 patients), surgery alone (42 patients), or postoperative RT (41 patients). Preoperative RT dose levels were either 2000 rad in five fractions (33 patients) or 5000 rad in 25 fractions (15 patients). Postoperative RT dosages were 5000 to 6000 rad in 6 to 6 1/2 weeks. Surgical procedures included either subtotal or total laryngectomy and radical neck dissection. Tumor control was achieved in 21 of 42 patients (50%) treated with surgery alone, 23 of 48 patients (48%) treated with preoperative RT, and 29 of 41 patients (71%) treated with postoperative RT (P . 0.005). The actuarial, recurrence-free survival at 5 years was 36% and 35%, respectively, in the surgery alone or preoperative RT groups as compared to 55% in postoperatively irradiated patients. The authors conclude that advanced but resectable supraglottic carcinomas may be best treated with surgery followed by RT, rather than with surgery alone or with combined preoperative RT and surgery

    Full Text Available Vertigo and dizziness are common symptoms in the general population. While the clinical picture is well known and widely described, there are different interpretations of Benign Paroxysmal Positional Vertigo. The purpose of this case report was to describe the treatment of a 56 year old woman with complains of positional vertigo for 35 consecutive years. She suffered from a sudden onset of rotatory, unilateral horizontal canal type benign paroxysmal positional vertigo (BPPV. The symtoms started a day after falling from a bus, where she injured her head. Otherwise her medical history was unremarkable. She was treated with an individualized home exercise program of eye movement exercises, Brandt/Daroff exercises, and general conditioning exercises (i.e., laying on the left side from sitting on the bed, while the head rotated 45 degrees to the right, waiting for about one minue; twice a day on gradual basis, not laying on the side all the way, but to use enough pillows to lay about at 60 degrees. Four weeks from the start of physical therapy, the patient was free of symptoms, even when her neck was in the extended position.

    The aim of this paper is to evaluate the clinical, radiographic, and histopathological findings and treatment modalities in all cases of ameloblastomas treated at the Sao Paulo Cancer Hospital, between 1953 and 2003. 121 case reports were retrieved from the medical files. Data were reviewed and statistical analysis was performed using Kaplan-Meyer method and Cox proportional risk model. The patients' age ranged from 2 to 82 years (mean 33.2 years), with a slight female prevalence. Most cases were located in the posterior mandible (80%). Radiographically, 60% showed a multilocular pattern. 113 casees were solid ameloblastomas, and plexiforme subtype was the most common. Solid tumours were treated by wide resection, curettage and criosurgery, or curettage alone, and unicystic tumours by curettage and/or cryotherapy. The global mean recurrence rate was 22%, with a mean follow-up of 9.7 years. The ameloblastomas were predominantly solid, affecting the posterior mandible. Important factors for outcome were radiographically multilocular lesions, the presence of ruptured basal cortical bone and histologically follicular tumours. PMID:20045283

    Addressed some factual inaccuracies and presented alternative positions on key issues raised in the article by Greene and Ablon (this issue) on the question, "What does the Multimodal Treatment Study (MTA) tell us about effective psychosocial treatment for attention deficit hyperactivity disorder (ADHD)?" The Greene and Ablon critique does not present for the reader's consideration the full range of findings from the MTA study, notably those most relevant to psychosocial treatment, and articulates a theoretical position that effective treatment requires matching treatment to children's assessed needs, an approach not taken in the MTA study. In this article, I present the full range of findings from the MTA study related to psychosocial treatment effects, correct the misperceptions that exist about the study based on limited reviews such as Greene and Ablon's, and review the empirical and experimental design issues that produced the decision by the MTA investigative team to study the effects of intensive, comprehensive psychosocial treatment. I argue that the questions asked by the MTA study about psychosocial treatment were important, relevant, and were addressed well in the MTA study design. PMID:11294072

    The world has a water deficit, mostly located in developing countries. For example, in Colombia, water deficit is a major concern and it increases in rural areas, where the rate of accessibility to drinking water is of 33.26% in 2005. Since the 1970s, the most used technology for water purification is the conventional physicochemical process. The most common coagulant used in this process is aluminum sulfate (alum). This study focuses on a comparison between Moringa oleifera seeds and alum for water treatment in different natural waters. Results showed that M. oleifera removed 90% turbidity and alum 96% from water samples from the tested natural brook. However, color removal for M. oleifera was 95 and 80.3% for alum. For water-polluted samples, both coagulants have shown high efficiency (100%) in color and turbidity removal. Usage of natural coagulants (i.e., M. oleifera) instead of chemical ones (i.e., alum) are more convenient in rural areas where the economic situation and accessibility of those products are key elements to maintain fresh water treatment standards. Additionally, results demonstrated that high dosages M. oleifera did not affect the optimal value in terms of color and turbidity removal. In rural and developing countries, this is important because it does not require a sophisticated dosing equipment. PMID:26437662

    The transportability of Multisystemic Therapy (MST) for the treatment of juvenile offenders in a community-based context was examined in the current study. Results of this New Zealand study showed that significant pre- to posttreatment improvements occurred on most indicators of ultimate (i.e., offending behavior) and instrumental (i.e., youth compliance, family relations) treatment outcomes. Reductions in offending frequency and severity continued to improve across the 6- and 12-month follow-up intervals. In comparison to benchmarked studies, the current study demonstrated a more successful treatment completion rate. Additionally, overall treatment effect sizes were found to be clinically equivalent with the results of previous MST outcome studies with juvenile offenders and significantly greater than the effect sizes found in the control conditions. The findings of this evaluation add to the growing body of evidence that supports MST as an effective treatment for antisocial youth. PMID:19364207

  18. Studies on electrochemical treatment of wastewater contaminated with organotin compounds

    International Nuclear Information System (INIS)

    Different anode materials were tested to evaluate their suitability to eliminate organotin compounds electrochemically from shipyard process waters. The capacity of two types of anode materials was investigated: niobium coated with boron-doped diamond (BDD) and titanium coated with iridium dioxide (Ti/IrO2). The aim of this work was to characterize the performance of the process using both anode materials at different current densities, and also to evaluate the generation of by-products. A further objective of this work was to evaluate if operating at low potentials with BDD anodes (to avoid the generation of elemental oxygen) the consumption of energy for degradation of pollutants could be minimized. The processes were tested on synthetic and real shipyard water containing approximately 25,000 ng L-1 of tributyltin (TBT) (as Sn) and 5000 ng L-1 dibutyltin. The range of current densities was between 6 and 70 mA cm-2. The results showed that electrochemical treatment is suitable to eliminate organotins down to very low concentrations following a stepwise debutylation mechanism. Both anode materials exhibited a similar performance with energy consumption in the range of 7-10 kWh m-3 in order to decrease organotins down to 100 ng L-1 (as Sn). For the water composition tested, BDD did not outperform Ti/IrO2 as initially expected, most probably because organotins were not only oxidized by ·OH, but also by active chlorine compounds generated by the oxidation of chloride present in the wastewater (1.6 g L-1, Cl-) with both anode materials. It was also found that the residual oxidants remaining in the treated effluent had to be eliminated if the water is to be discharged safely in the aquatic environment

    Our previous studies have suggested that digital blood pressure response to cooling could provide a measure of the efficacy of treatments that are administered to patients with Raynaud phenomenon (RP). This method was used on 158 primary RP patients participating in a multicenter, randomized clinical trial that compared the efficacy of sustained-release nifedipine with temperature biofeedback in the treatment of RP. A pill placebo and electromyography served as controls. The response to local finger cooling was measured at 30 degrees, 20 degrees, 15 degrees and 10 degrees C in a temperature-controlled room under standardized conditions. The results showed that, at the 15 degrees C and 10 degrees C local cooling temperatures, the patients in the nifedipine group had a higher mean digital systolic blood pressure, a higher relative digital systolic blood pressure (RDSP), a smaller proportion of subjects with RDSP < 70% and a smaller proportion of subjects with a zero reopening pressure than the patients in the three other treatment groups. These results were statistically significant at 10 degrees C, the nifedipine group being significantly different from all others (p < 0.05); no significant difference was found between the three other treatment groups.

    The purpose of this study was to examine the patient- and treatment-related etiologic factors of external root resorption. This study consisted of 163 patients who had completed orthodontic treatments and taken the pre- and post-treatment panoramic and lateral cephalometric radiographs. The length of tooth was measured from the tooth apex to the incisal edge or cusp tip on the panoramic radiograph. Overbite and overjet were measured from the pre- and post-treatment lateral cephalometric radiographs. The root resorption of each tooth and the factors of malocclusion were analyzed with an analysis of variance. A paired t test was performed to compare the mean amount of root resorption between male and female, between extraction and non-extraction cases, and between surgery and non-surgery groups. Correlation coefficients were measured to assess the relationship between the amount of root resorption and the age in which the orthodontic treatment started, the degree of changes in overbite and overjet, and the duration of treatment. Maxillary central incisor was the most resorbed tooth, followed by the maxillary lateral incisor, the mandibular central incisor, and the mandibular lateral incisor. The history of tooth extraction was significantly associated with the root resorption. The duration of orthodontic treatment was positively correlated with the amount of root resorption. These findings show that orthodontic treatment should be carefully performed in patients who need the treatment for a long period and with a pre-treatment extraction of teeth.

    The activation of signaling cascades in response to extracellular and intracellular stimuli to control cell growth, proliferation and survival, is orchestrated by protein kinases via phosphorylation. A critical issue is the study of the mechanisms of cancer cells for the development of more effective drugs. With the application of the new proteomic technologies, together with the advancement in the sequencing of the human proteome, patients will therefore be benefited by the discovery of novel therapeutic and/or diagnostic protein targets. Furthermore, the advances in proteomic approaches and the Human Proteome Organization (HUPO) have opened a new door which is helpful in the identification of patients at risk and towards improving current therapies. Modification of the signaling-networks via mutations or abnormal protein expression underlies the cause or consequence of many diseases including cancer. Resulting data is used to reveal connections between genes proteins and compounds and the related molecular pathways for underlining disease states. As a delegate of HUPO, for human proteome on children assays and studies, we, at Hospital Universitario Niño Jesús, are seeking to support the human proteome in this context. Clinical goals have to be clearly established and proteomics experts have to set up the appropriate proteomic strategy, which coupled to bioinformatics will make it possible to achieve new therapies for patients with poor prognosis. We envision to combine our up-coming data to the HUPO organization in order to support international efforts to advance the cure of cancer disease. PMID:26055493

    This study aimed to evaluate the use of ozone to treat recurrent aphthous stomatitis (RAS). Consecutive sixty-nine participants with RAS were recruited into this non-randomized double blind, controlled cohort observational study (test group). A control group of 69 RAS patients who matched test group with age and gender was recruited. RAS lesions in test group were exposed to ozone in air for 60 seconds while controls received only air. Ulcer size and pain were recorded for each participant at baseline and daily for 15 days. Ulcer duration was determined by recording the time taken for ulcers to disappear. The main outcome measures were pain due to the ulcer, ulcer size and ulcer duration. 138 RAS participants (69 participants and 69 controls) were analyzed. Ulcer size was reduced starting from the second day in test group and from the fourth day in controls (p ≤ 0.004). Pain levels were reduced starting from the first day in the test group and from the third day in controls (p ≤ 0.001). Ulcer duration, ulcer size after day 2 and pain levels were more reduced in the test group. In conclusion, application of ozone on RAS lesions for 60 seconds reduced pain levels and enhanced ulcers’ healing by reducing ulcers’ size and duration. PMID:27301301

  6. Study of the aqueous chemical treatment of uranium zirconium fuels

    International Nuclear Information System (INIS)

    A dry process has been studied for separating the uranium from the zirconium-either for recovering the enriched uranium from fuel element production waste, or with a view to treating this waste after irradiation. In this process the alloy is treated with hydrochloric acid at 400 deg. C in a fluidized corundum bed which causes the zirconium to volatilize as tetrachloride and the uranium to form the trichloride. This latter is then converted to the hexafluoride by attack with fluorure. After the laboratory tests, a first pilot plant with a capacity of 1 kg of alloy was tried out at the Fontenay-aux-Roses Nuclear Research Centre; this made it possible to fix the operational conditions for the process. An industrial scale plant was then built with the collaboration of the from Kuhlmann, and operated until a satisfactory process had been developed for treating the waste. This installation treats 3 kg/h of alloy with a yield for the hydrochloric acid of about 50 per cent and with a uranium loss in the zirconium tetrachloride of about 0.1 per cent. An active pilot plant capable of treating of treating a few kilos of irradiated alloy is now being studied. (authors)

Eleven Hobson model seven master-slave manipulators allow inner manipulations. Then the inner equipment is described briefly. (author)

  9. BIOLOGICAL EFFECTS OF PULSED SHORT WAVE TREATMENT. AN EXPERIMENTAL STUDY

    2015-02-01

    Full Text Available Pulsed short waves are short electromagnetic waves emitted as intermittent trains with a fixed duration, separated by free intervals of variable duration. The biological effects of pulsed short waves could be explained according to most of the authors by an activation of cellular enzymatic reactions, a stimulation of energy metabolism, a stimulation of liver function, of adrenal gland function and of the reticulocyte system, changes in cell permeability, by an increase of peripheral blood flow through the enhancement of local vascularization. This research aimed to investigate the biological effects of exposure to pulsed short waves at different doses on the adrenal glands of experimental animals, by structural and ultrastructural studies. The study included 35 animals assigned to 4 groups. Group I included 10 experimental animals exposed to radiation at a dose of 1/80 impulses/sec, group II, 10 animals exposed to a dose of 4/400 impulses/sec, group III, 10 animals exposed to a dose of 6/600 impulses/sec, for 10 min/day, and the control group consisted of 5 unexposed animals. Structural and ultrastructural changes of adrenal glands induced by the dose of 4/400 impulses/sec, compared to the unexposed control group and the dose of 1/80 impulses/sec, include an intensification of protein synthesis processes, an enhancement of energy metabolism in providing the energy required for an increased production of hormones, an intensification of collagen fiber synthesis processes in the capsule, necessary for healing. It was demonstrated that this dose induced an intensification of hormone synthesis and secretion, a stimulation of adrenal function. At the dose of 6/600 cycles/sec, a slight diminution of hormone synthesis and secretion activity was found, which was not below the limits existing in the unexposed control group, but was comparable to group II. This dose is probably too strong for experimental animals, inducing them a state of stress. The

    This study utilizes available clinical information from client records to explore patterns of termination from mental health treatment among adolescents at an urban outpatient mental health center. The analysis focuses on how and why adolescents terminate from treatment and identifies variables associated with "acknowledged" and "unacknowledged" terminations. Findings indicate that termination was acknowledged infrequently, often a brief process that occurred almost as frequently by telephone as in the context of treatment. Contrary to "practice wisdom" concerning treatment termination, adolescents who "dropped out" without a "clinical process" reported considerably more engagement in treatment than those who acknowledged the termination of treatment. Recommendations for a more "open door" policy and a more flexible practice with adolescents are discussed. PMID:11837364

    Zidovudine (AZT) is the antiretroviral drug most frequently used for the treatment of Acquired Immunodeficiency Syndrome. Its low oral bioavailability demands the development of innovative strategies to overcome the first pass metabolism. The nasal route is an option for enhanced therapeutic efficacy and to reduce the extent of the first-pass effect. In this article, AZT loaded chitosan nanoparticles were prepared by a modified ionotropic gelation method with sodium tripolyphosphate. The increase proportion of CS (NP1 10:01 (w/w)) promoted the formation of smaller nanoparticles (260 nm), while raising the proportion of TPP (NP2 5:1 w/w) increased the nanoparticles size (330 nm). The incorporation of AZT increased the nanoparticles size for both AZT-loaded nanoparticles AZT-loaded NP1 (406 nm) and AZT-loaded NP2 (425 nm). The incorporation of AZT into NP1 did not change the electrophoretic mobility, however, in AZT-loaded NP2 there was a significant increase. The positive surface of the nanoparticles is very important for the mucoadhesive properties due interaction with the sialic groups of the mucin. Nuclear resonance magnetic data showed that the higher concentration of chitosan in the nanoparticles favored the interaction of few phosphate units (pyrophosphate) by ionic interaction Scanning electron microscopy, revealed that the nanoparticles are nearly spherical shape with porous surface. The entrapment efficiency of AZT, was 17.58% ± 1.48 and 11.02% ± 2.05 for NP1 and NP2, respectively. The measurement of the mucoadhesion force using mucin discs and nasal tissue obtained values of NP1 = 2.12 and NP2 = 4.62. In vitro permeation study showed that the nanoparticles promoted an increase in the flux of the drug through the nasal mucosa. In view of these results, chitosan nanoparticles were found to be a promising approach for the incorporation of hydrophilic drugs and these results suggest that the CS-containing nanoparticles have great potential for nasal AZT

    Behavioral and pharmacological treatments for children with attention deficit/hyperactivity disorder (ADHD) were evaluated to address whether endpoint outcomes are better depending on which treatment is initiated first and, in case of insufficient response to initial treatment, whether increasing dose of initial treatment or adding the other treatment modality is superior. Children with ADHD (ages 5-12, N = 146, 76% male) were treated for 1 school year. Children were randomized to initiate treatment with low doses of either (a) behavioral parent training (8 group sessions) and brief teacher consultation to establish a Daily Report Card or (b) extended-release methylphenidate (equivalent to .15 mg/kg/dose bid). After 8 weeks or at later monthly intervals as necessary, insufficient responders were rerandomized to secondary interventions that either increased the dose/intensity of the initial treatment or added the other treatment modality, with adaptive adjustments monthly as needed to these secondary treatments. The group beginning with behavioral treatment displayed significantly lower rates of observed classroom rule violations (the primary outcome) at study endpoint and tended to have fewer out-of-class disciplinary events. Further, adding medication secondary to initial behavior modification resulted in better outcomes on the primary outcomes and parent/teacher ratings of oppositional behavior than adding behavior modification to initial medication. Normalization rates on teacher and parent ratings were generally high. Parents who began treatment with behavioral parent training had substantially better attendance than those assigned to receive training following medication. Beginning treatment with behavioral intervention produced better outcomes overall than beginning treatment with medication. PMID:26882332

    Full Text Available Abstract Background More than 70% of patients with depression who see their doctors experience insomnia. Insomnia treatment is a very important link for depression treatment. Furthermore, antidepression treatment is also important for depression insomnia. In acupuncture, LU-7 (Lie Que and KID-6 (Zhao Hai, which are two of the eight confluence points in meridian theory, are used as main points. An embedded needle technique is used, alternately, at two groups of points to consolidate the treatment effect. These two groups of points are BL-15 (Xin Shu with BL-23 (Shen Shu and BL-19 (Dan Shu with N-HN-54 (An Mian. The effectiveness of these optimized acupuncture formulas is well proven in the practice by our senior acupuncturists in Guangdong Provincial Hospital of TCM. This study has been designed to examine whether this set of optimized clinical formulas is able to increase the clinical efficacy of depression insomnia treatment. Methods/design In this randomized controlled multicenter trial, all the eligible participants are diagnosed with depression insomnia. All participants are randomly assigned to one of two groups in a ratio of 1:1 and receive either conventional acupuncture treatment or optimized acupuncture treatment. Patients are evaluated using the Pittsburgh Sleep Quality Index(PSQIand the Hamilton rating scale(HAMD for depression. The use of antidepression and hypnotics drugs is also considered. Results are obtained at the start of treatment, 1 and 2 months after treatment has begun, and at the end of treatment. The entire duration of the study will be approximately 36 months. Discussion A high quality of trial methodologies is utilized in the study, and the results may provide better evidence for the effectiveness of acupuncture as a treatment for depression insomnia. The optimized acupuncture formula has potential benefits in increasing the efficacy of treating depression insomnia. Trial registration The trial was registered in

    This pilot study aimed to refine a treatment approach for traumatic grief due to violent loss. Our Traumatic Grief Treatment Program, a modification of Shear's complicated grief treatment (Shear et al., 2005), comprises psychoeducation, in vivo exposure, imaginal exposure, discussion of memories about and imaginal conversation with the deceased. Thirteen of 15 Japanese women suffering from posttraumatic stress disorder (PTSD) due to traumatic grief completed 12 to 16 weekly individual sessions based on their therapists' recommendations. Assessment scales included the Inventory of Complicated Grief, the Impact of Event Scale-Revised, and the Center for Epidemiologic Studies Depression Scale. There was significant reduction in symptom severity at treatment end, and symptom levels remained low throughout the 12-month follow-up period. Based on Jacobson's Reliable Change Index, 46% showed change on all 3 measures. These findings suggest that our treatment model may be feasible for treating traumatic grief with PTSD in non-Western settings. PMID:21780192

    Treatment for human papillomavirus (HPV)-associated anal canal disease has been unsatisfactory. The objective of our study was to determine the treatment outcome in our cohort with anal HPV disease. Overall, 181 patients were evaluated over a median period of 19.1 months (range = 2.8-125.5). Eighty-eight patients (48.6%) with high-grade anal intraepithelial neoplasia (AIN) and 82 patients (45.3%) with low-grade AIN underwent treatment. One hundred and forty-one patients (77.9%) received laser ablative treatment as an outpatient procedure. The treatment yielded cure, defined as a disease-free state at 12 months after treatment, in 63.0% (114/181). Median time to cure for the cohort was 31.5 months (95% confidence interval: 23.0-40.0). Treatment outcome showed no evidence of being affected by age, sexual preference, history of smoking or presence of high-grade disease. Median time to cure was significantly affected by a positive HIV status (P = 0.02) and the extent (volume) of the disease (P = 0.01). Contrary to the current view that treatment of HPV-related anal disease is difficult, unrewarding due to recurrences and may lead to substantial morbidity, we demonstrate that effective treatment is possible for both low- and high-grade AIN. These findings should help with the general desire to introduce screening for AIN for at-risk groups. PMID:18574114

    Full Text Available Abstract Background Non-adherence to tuberculosis (TB treatment is an important barrier for TB control programs because incomplete treatment may result in prolonged infectiousness, drug resistance, relapse, and death. The aim of the present study is to explore enablers and barriers in the management of TB treatment during the first five months of treatment in Addis Ababa, Ethiopia. Methods Qualitative study which included 50 in-depth interviews and two focus groups with TB patients, their relatives and health personnel. Results We found that loss of employment or the possibility to work led to a chain of interrelated barriers for most TB patients. Daily treatment was time-consuming and physically demanding, and rigid routines at health clinics reinforced many of the emerging problems. Patients with limited access to financial or practical help from relatives or friends experienced that the total costs of attending treatment exceeded their available resources. This was a barrier to adherence already during early stages of treatment. A large group of patients still managed to continue treatment, mainly because relatives or community members provided food, encouragement and sometimes money for transport. Lack of income over time, combined with daily accumulating costs and other struggles, made patients vulnerable to interruption during later stages of treatment. Patients who were poor due to illness or slow progression, and who did not manage to restore their health and social status, were particularly vulnerable to non-adherence. Such patients lost access to essential financial and practical support over time, often because relatives and friends were financially and socially exhausted by supporting them. Conclusion Patients' ability to manage TB treatment is a product of dynamic processes, in which social and economic costs and other burdens change and interplay over time. Interventions to facilitate adherence to TB treatment needs to address both

    Full Text Available Nucleoside Reverse Transcriptase Inhibitors (NRTIs have not only improved therapeutic outcomes in the treatment of HIV infection but have also led to an increase in associated metabolic complications of NRTIs. Naringin’s effects in mitigating NRTI-induced complications were investigated in this study. Wistar rats, randomly allotted into seven groups (n = 7 were orally treated daily for 56 days with 100 mg/kg zidovudine (AZT (groups I, II III, 50 mg/kg stavudine (d4T (groups IV, V, VI and 3 mL/kg of distilled water (group VII. Additionally, rats in groups II and V were similarly treated with 50 mg/kg naringin, while groups III and VI were treated with 45 mg/kg vitamin E. AZT or d4T treatment significantly reduced body weight and plasma high density lipoprotein concentrations but increased liver weights, plasma triglycerides and total cholesterol compared to controls, respectively. Furthermore, AZT or d4T treatment significantly increased oxidative stress, adiposity index and expression of Bax protein, but reduced Bcl-2 protein expression compared to controls, respectively. However, either naringin or vitamin E significantly mitigated AZT- or d4T-induced weight loss, dyslipidemia, oxidative stress and hepatocyte apoptosis compared to AZT- or d4T-only treated rats. Our results suggest that naringin reverses metabolic complications associated with NRTIs by ameliorating oxidative stress and apoptosis. This implies that naringin supplements could mitigate lipodystrophy and dyslipidemia associated with NRTI therapy.

    Full Text Available Abstract Background A large number of randomized controlled studies have clearly demonstrated that psychological interventions are effective in the treatment of depression. The number of studies in this area is increasing rapidly. In this paper, we present a database of controlled and comparative outcome studies on psychological treatments of depression, based on a series of meta-analyses published by our group. The database can be accessed freely through the Internet. Description We conducted a comprehensive literature search of the major bibliographical databases (Pubmed; Psycinfo; Embase; Cochrane Central Register of Controlled Trials and we examined the references of 22 earlier meta-analyses of psychological treatment of depression. We included randomized studies in which the effects of a psychological therapy on adults with depression were compared to a control condition, another psychological intervention, or a combined treatment (psychological plus pharmacological. We conducted nine meta-analyses of subgroups of studies taken from this dataset. The 149 studies included in these 9 meta-analyses are included in the current database. In the 149 included studies, a total of 11,369 patients participated. In the database, we present selected characteristics of each study, including characteristics of the patients (the study population, recruitment method, definition of depression; characteristics of the experimental conditions and interventions (the experimental conditions, N per condition, format, number of sessions; and study characteristics (measurement times, measures used, attrition, type of analysis and country. Conclusion The data on the 149 included studies are presented in order to give other researchers access to the studies we collected, and to give background information about the meta-analyses we have published using this dataset. The number of studies examining the effects of psychological treatments of depression has increased

    Introduction Chronic thoracic aortic aneurysm (CTAA) affecting the arch or descending aorta is an indolent but life-threatening condition with a rising prevalence as the UK population ages. Treatment may be in the form of open surgical repair (OSR) surgery, endovascular stent grafting (ESG) or best medical therapy (BMT). Currently, there is no consensus on the best management strategy, and no UK-specific economic studies that assess outcomes beyond the chosen procedure, but this is required in the context of greater demand for treatment and limited National Health Service (NHS) resources. Methods and analysis This is a prospective, multicentre observational study with statistical and economic modelling of patients with CTAA affecting the arch or descending aorta. We aim to gain an understanding of how treatments are currently chosen, and to determine the clinical effectiveness and cost-effectiveness of the three available treatment strategies (BMT, ESG and OSR). This will be achieved by: (1) following consecutive patients who are referred to the teams collaborating in this proposal and collecting data regarding quality of life (QoL), medical events and hospital stays over a maximum of 5 years; (2) statistical analysis of the comparative effectiveness of the three treatments; and (3) economic modelling of the comparative cost-effectiveness of the three treatments. Primary study outcomes are: aneurysm growth, QoL, freedom from reintervention, freedom from death or permanent neurological injury, incremental cost per quality-adjusted life year gained. Ethics and dissemination The study will generate an evidence base to guide patients and clinicians to determine the indications and timing of treatment, as well as informing healthcare decision-makers about which treatments the NHS should provide. The study has achieved ethical approval and will be disseminated primarily in the form of a Health Technology Assessment monograph at its completion. Trial registration number

    Full Text Available Abstract Background The purpose of this study was to assess the impact of drug abuse treatment in Peru that used the therapeutic community (TC model. Program directors and several staff members from all study treatment facilities received two to eight weeks of in-country training on how to implement the TC treatment model prior to the follow-up study. Methods This outcome study involved 33 TC treatment facilities and 509 former clients in Lima and other cities in five providences across Peru. A retrospective pre-test (RPT follow-up design was employed in which 30-day use of illegal drugs and alcohol to intoxication was measured at baseline retrospectively, at the same time of the six-month follow-up. In-person interview data were collected from directors of 73 percent of the eligible TC organizations in January and February 2003 and from former 58 percent of the eligible TC former clients between October 2003 and October 2004. Drug testing was conducted on a small sample of former clients to increase the accuracy of the self-reported drug use data. Results Medium to large positive treatment effects were found when comparing 30-day illegal drug and alcohol use to intoxication before and six months after receiving treatment. As a supplemental analysis, we assumed the 42 percent of the former clients who were not interviewed at the six month assessment had returned to drugs. These results showed medium treatment effects as well. Hierarchical Generalized Linear Modeling (HGLM results showed higher implementation fidelity, less stigma after leaving treatment, and older clients, singly or in combination are key predictors of treatment success. Conclusion This study found that former clients of drug and alcohol treatment in facilities using the TC model reported substantial positive change in use of illegal drugs and alcohol to intoxication at a six-month follow-up. The unique contribution of this study is that the results also suggest attention should

    Context Efficacy of antidepressant treatment in depression is unsatisfactory as one in three patients does not fully recover even after several treatment trials. Genetic factors and clinical characteristics contribute to the failure of a favorable treatment outcome. Objective To identify genetic and clinical determinants of antidepressant treatment outcome in depression. Design Genome-wide pharmacogenetic association study with two independent replication samples. Setting We performed a genome-wide association (GWA) study in patients from the Munich-Antidepressant-Response-Signature (MARS) project and in pooled DNA from an independent German replication sample. A set of 328 single nucleotide polymorphisms (SNPs) highly related to outcome in both GWA studies was genotyped in a sample of the Sequenced-Treatment-Alternatives-to-Relieve-Depression (STAR*D) study. Participants 339 inpatients suffering from a depressive episode (MARS sample), further 361 depressed inpatients (German replication sample), and 832 outpatients with major depression (STAR*D sample). Main Outcome Measures We generated a multi-locus genetic variable describing the individual number of alleles of the selected SNPs associated with beneficial treatment outcome in the MARS sample (“response” alleles) to evaluate additive genetic effects on antidepressant treatment outcome. Results Multi-locus analysis revealed a significant contribution of a binary variable categorizing patients as carriers of a high vs. low number of response alleles in predicting antidepressant treatment outcome in both samples, MARS and STAR*D. In addition, we observed that patients with a comorbid anxiety disorder in combination with a low number of response alleles showed the least favorable outcome. Conclusion Our results demonstrate the importance of multiple genetic factors in combination with clinical features to predict antidepressant treatment outcome underscoring the multifactorial nature of this trait.

    Full Text Available Recent studies have indicated the potential clinical use of near infrared spectroscopy (NIRS as a tool in assisting the diagnosis of major depressive disorder (MDD; however, it is still unclear whether NIRS signal changes during cognitive task are state- or trait-dependent, and whether NIRS could be a neural predictor of treatment response. Therefore, we conducted a longitudinal study to explore frontal haemodynamic changes following antidepressant treatment in medication-naïve MDD using 52-channel NIRS. This study included 25 medication-naïve individuals with MDD and 62 healthy controls (HC. We performed NIRS scans before and after antidepressant treatment and measured changes of [oxy-Hb] activation during a verbal fluency task (VFT following treatment. Individuals with MDD showed significantly decreased [oxy-Hb] values during a VFT compared with HC in the bilateral frontal and temporal cortices at baseline. There were no [oxy-Hb] changes between pre- and post-antidepressant treatment time points in the MDD cohort despite significant improvement in depressive symptoms. There was a significant association between mean [oxy-Hb] values during a VFT at baseline and improvement in depressive symptoms following treatment in the bilateral inferior frontal and middle temporal gyri in MDD. These findings suggest that hypofrontality response to a VFT may represent a potential trait marker for depression rather than a state marker. Moreover, the correlation analysis indicates that the NIRS signals before the initiation of treatment may be a biological marker to predict patient's clinical response to antidepressant treatment. The present study provides further evidence to support a potential application of NIRS for the diagnosis and treatment of depression.

    A review of the literature suggested that prolonged treatment time may lessen the probability of cure for patients with advanced squamous cell carcinoma of the upper aerodigestive tract. To shorten treatment time, rapid sequence treatment (RST) was devised in which chemotherapy, surgery, and irradation were administered in a total treatment time of 8 weeks. Twelve patients were treated and followed 3 years or longer. Medical complications were minor. Osteonecrosis occurred in each of the first five patients and was the only major complication of the protocol. Surgical techniques were modified, and no additional patient developed osteonecrosis. No patient developed local or regional recurrence. Two patients developed distant metastases and three other patients developed second primaries. Absolute survival was 50%. Rapid sequence treatment is an aggressive and potentially hazardous protocol that yielded encouraging results in this pilot study.

    Medication nonadherence decreases the success of clinical treatment and the efficient use of resources, thereby creating a barrier to effective health care. In this report, we describe the achievement of treatment collaboration through motivational interviews (MI) in a patient with treatment-resistant schizophrenia. In this case study, we conducted six MIs during which we asked open-ended and reflective questions, established empathy with the patient, and developed discrepancies, leading to ambivalent feelings being revealed. We used the importance, confidence and self-efficacy ruler. The MI method can be used to ensure continued treatment effectiveness, to increase patient awareness about the disease and benefits of treatment, and to increase patients' self-efficacy.

    Full Text Available A study was conducted in São Paulo, Brazil, to compare azithromycin with thiamphenicol for the single-dose treatment of chancroid. In all, 54 men with chancroid were tested. The etiology was determined by clinical characterization and direct bacterioscopy with Gram staining. None of the patients had positive serology or dark-field examination indicating active infection with Treponema pallidum. Genital infections due to Neisseria gonorrhoeae and herpes simplex virus were excluded by polymerase chain reaction testing. For 54 patients with chancroid, cure rates with single-dose treatment were 73% with azithromycin and 89% with thiamphenicol. HIV seropositivity was found to be associated with treatment failure (p=0.001. The treatment failed in all HIV positive patients treated with azithromycin (p=0.002 and this drug should be avoided in these co-infected patients. In the view of the authors, thiamphenicol is the most indicated single-dose regimen for chancroid treatment.

    2013-10-01

    Full Text Available In order to enhance external hardness and strength, a large-scale hydraulic gate track should go through heat treatment. The current design method of hydraulic gate wheels and tracks is based on Hertz contact linear elastic theory, and does not take into account the changes in mechanical properties of materials caused by heat treatment. In this study, the heat treatment parameters were designed and analyzed according to the bearing mechanisms of the wheel and track. The quenching process of the track was simulated by the ANSYS program, and the temperature variation, residual stress, and deformation were obtained and analyzed. The metallurgical structure field after heat treatment was predicted by the method based on time-temperature-transformation (TTT curves. The results show that the analysis method and designed track heat treatment process are feasible, and can provide a reference for practical projects.

    Full Text Available Ulrike H Mitchell,1 Sterling C Hilton2 1Brigham Young University, Department of Exercise Sciences, 2Department of Educational Leadership and Foundations, Provo, UT, USA Background: In 2003, the 10-question International Restless Legs Syndrome Study Group Rating Scale (IRLS was developed as a means of assessing the severity of restless legs syndrome. Two subscales were identified: symptom severity (SS 1 and symptom impact (SS 2. Only one study has investigated the subscales' responsiveness to a 12-week treatment with ropinirole. This current study was undertaken to assess the impact of a 4-week, non-pharmaceutical treatment on the two subscales and to explore whether or not both subscales were impacted by the observed placebo effect. Methods: The pooled data from questionnaires of 58 patients (41 from both treatment groups and 17 from the sham treatment control group, who participated in two clinical studies, were reviewed. Their change in score over a 4-week trial was computed. The average change in both subscales in both groups was computed and t-tests were performed. Results: In the treatment group, the average scores of both subscales changed significantly from baseline to week 4 (P<0.005 for both. Compared to the control, SS 1 changed (P<0.001, but not SS 2 (P=0.18. In the sham treatment group, the scores for SS 1 changed significantly (P=0.002, but not for SS 2 (P=0.2. Conclusion: This study corroborated findings from an earlier study in which both subscales changed with a 12-week drug treatment. It also showed that the observed placebo effect is attributed to a small but significant change in symptom severity, but not symptom impact.

    Rasagiline (Azilect) is a potent, highly selective and irreversible inhibitor of monoamine oxidase type B of the second generation. Rasagiline is indicated for the treatment of Parkinson's disease (PD) as monotherapy (without levodopa) or as adjunct therapy (with levodopa) in patients with end of dose fluctuations. The efficacy and tolerability of rasagiline has been demonstrated in large-scale, controlled clinical studies in patients with early PD as well as with more advanced PD. This multicentred post-marketing observational study included an investigation of the efficacy and tolerability of rasagiline in a large patient population under conditions of the daily routine in neurologic practice with a special attention on the collection of data regarding a patients' subjective evaluation of quality of life. A total of 754 patients with Parkinson's disease were enrolled, 545 of the patients (63% male patients, mean age 68 years, mean duration of PD 6 years, Hoehn & Yahr stage II to III in 69% of the patients) started rasagiline 1 mg/day as adjunct therapy for up to 4 months. The PD symptoms were rated by the physicians using the Columbia University Rating Scale (CURS) and the clinical fluctuations subscale of the Unified Parkinson's Disease Rating Scale (UPDRS, part IV B). Different aspects of quality of life were rated by the patients using the self-rating Parkinson's Disease Questionaire (PDQ-39). In addition, patients documented the number of hours spend in the OFF-state in "24-hour" home diaries prior to each of the assessment visits. During the treatment period rasagiline was most frequently co-administered with levodopa/DCI (81.7%) and/or dopamine agonists (65.8%). The mean treatment duration was 117.4 (+/-36.4) days, during which PD medication remained unchanged in 86.6% of the cases. The improvement rates in each of the CURS items ranged between 31.1% to 48.4% and the total score was reduced by 22% under the therapy of rasagiline. In the motor part (tremor

    Full Text Available Abstract Background Surveys on prescription patterns for antipsychotics in the Scandinavian public health system are scarce despite the prevalent use of these drugs. The clinical differences between antipsychotic drugs are mainly in the areas of safety and tolerability, and international guidelines for the treatment of schizophrenia offer rational strategies to minimize the burden of side effects related to antipsychotic treatment. The implementation of treatment guidelines in clinical practice have proven difficult to achieve, as reflected by major variations in the prescription patterns of antipsychotics between different comparable regions and countries. The objective of this study was to evaluate the practice of treatment of schizophrenic patients with antipsychotics at discharge from acute inpatient settings at a national level. Methods Data from 486 discharges of patients from emergency inpatient treatment of schizophrenia were collected during a three-month period in 2005; the data were collected in a large national study that covered 75% of Norwegian hospitals receiving inpatients for acute treatment. Antipsychotic treatment, demographic variables, scores from the Global Assessment of Functioning and Health of the Nation Outcome Scales and information about comorbid conditions and prior treatment were analyzed to seek predictors for nonadherence to guidelines. Results In 7.6% of the discharges no antipsychotic treatment was given; of the remaining discharges, 35.6% were prescribed antipsychotic polypharmacy and 41.9% were prescribed at least one first-generation antipsychotic (FGA. The mean chlorpromazine equivalent dose was 450 (SD 347, range 25–2800. In the multivariate regression analyses, younger age, previous inpatient treatment in the previous 12 months before index hospitalization, and a comorbid diagnosis of personality disorder or mental retardation predicted antipsychotic polypharmacy, while previous inpatient treatment in

    Stereotactic body radiation therapy (SBRT) treatment planning and delivery can be accomplished using a variety of techniques that achieve highly conformal dose distributions. Herein, we describe a template-based automated treatment field approach that enables rapid delivery of more than 20 coplanar fields. A case study is presented to demonstrate how modest adaptations to traditional SBRT planning can be implemented to take clinical advantage of this technology. Treatment was planned for a left-sided lung lesion adjacent to the chest wall using 25 coplanar treatment fields spaced at 11° intervals. The plan spares the contralateral lung and is in compliance with the conformality standards set forth in Radiation Therapy and Oncology Group protocol 0915, and the dose tolerances found in the report of the American Association of Physicists in Medicine Task Group 101. Using a standard template, treatment planning was accomplished in less than 20 minutes, and each 10 Gy fraction was delivered in approximately 5.4 minutes. For those centers equipped with linear accelerators capable of automated treatment field delivery, the use of more than 20 coplanar fields is a viable SBRT planning approach and yields excellent conformality and quality combined with rapid planning and treatment delivery. Although the case study discusses a laterally located lung lesion, this technique can be applied to centrally located tumors with similar results.

  4. Computational Study of Porous Treatment for Altering Flap Side-Edge Flowfield

    Reynolds-averaged Navier-Stokes calculations are used to investigate porous side-edge treatment as a passive means for flap noise reduction. Steady-state simulations are used to infer effects of the treatment on acoustically relevant features of the mean flow near the flap side edge. Application of the porous treatment over a miniscule fraction of the wetted flap area (scaling with the flap thickness) results in significantly weaker side-edge vortex structures via modification of the vortex initiation and roll-up processes. At high flap deflections, the region of axial flow reversal associated with the breakdown of the side-edge vortex is also eliminated, indicating an absence of vortex bursting in the presence of the treatment. Potential ramifications of the mean-flow modifications for flap-noise reduction are examined in the light of lessons learned from recent studies on flap noise. Computations confirm that any noise reduction benefit via the porous treatment would be achieved without compromising the aerodynamic effectiveness of the flap. Results of the parameter study contribute additional insight into the measured data from the 7x10 wind tunnel at NASA Ames and provide preliminary guidance for specifying optimal treatment characteristics in terms of treatment location, spatial extent, and flow resistance of the porous skin.

    International Nuclear Information System (INIS)

    Purpose: The aim of this pharmaco-epidemiological study was to evaluate the prevalence of oropharyngeal candidiasis (OPC) in cancer patients treated with chemotherapy and/or radiotherapy. Methods and Materials: Signs and symptoms of OPC were noted for all patients. Antifungal therapeutic management was recorded in OPC patients. Patients receiving local antifungal treatments were monitored until the end of treatment. Results: Enrolled in the study were 2,042 patients with solid tumor and/or lymphoma treated with chemotherapy and/or another systemic cancer treatment and/or radiotherapy. The overall prevalence of OPC was 9.6% (95% confidence interval, 8.4%-11.0%] in this population. It was most frequent in patients treated with combined chemoradiotherapy (22.0%) or with more than two cytotoxic agents (16.9%). Local antifungal treatments were prescribed in 75.0% of OPC patients as recommended by guidelines. The compliance to treatment was higher in patients receiving once-daily miconazole mucoadhesive buccal tablet (MBT; 88.2%) than in those treated with several daily mouthwashes of amphotericin B (40%) or nystatin (18.8%). Conclusion: OPC prevalence in treated cancer patients was high. Local treatments were usually prescribed as per guidelines. Compliance to local treatments was better with once-daily drugs.

  6. Treatment planning for SBRT using automated field delivery: A case study

    International Nuclear Information System (INIS)

    Stereotactic body radiation therapy (SBRT) treatment planning and delivery can be accomplished using a variety of techniques that achieve highly conformal dose distributions. Herein, we describe a template-based automated treatment field approach that enables rapid delivery of more than 20 coplanar fields. A case study is presented to demonstrate how modest adaptations to traditional SBRT planning can be implemented to take clinical advantage of this technology. Treatment was planned for a left-sided lung lesion adjacent to the chest wall using 25 coplanar treatment fields spaced at 11° intervals. The plan spares the contralateral lung and is in compliance with the conformality standards set forth in Radiation Therapy and Oncology Group protocol 0915, and the dose tolerances found in the report of the American Association of Physicists in Medicine Task Group 101. Using a standard template, treatment planning was accomplished in less than 20 minutes, and each 10 Gy fraction was delivered in approximately 5.4 minutes. For those centers equipped with linear accelerators capable of automated treatment field delivery, the use of more than 20 coplanar fields is a viable SBRT planning approach and yields excellent conformality and quality combined with rapid planning and treatment delivery. Although the case study discusses a laterally located lung lesion, this technique can be applied to centrally located tumors with similar results

  7. Comparisons of treatment means when factors do not interact in two-factorial studies

    KAUST Repository

    Wei, Jiawei

    2011-05-06

    Scientists in the fields of nutrition and other biological sciences often design factorial studies to test the hypotheses of interest and importance. In the case of two-factorial studies, it is widely recognized that the analysis of factor effects is generally based on treatment means when the interaction of the factors is statistically significant, and involves multiple comparisons of treatment means. However, when the two factors do not interact, a common understanding among biologists is that comparisons among treatment means cannot or should not be made. Here, we bring this misconception into the attention of researchers. Additionally, we indicate what kind of comparisons among the treatment means can be performed when there is a nonsignificant interaction among two factors. Such information should be useful in analyzing the experimental data and drawing meaningful conclusions.

    The two stabilization treatment methods that are to be examined for their effectiveness in the treatment of both the unremediated and remediated nitrate salt wastes include (1) the addition of zeolite and (2) cementation. Zeolite addition is proposed based on the results of several studies and analyses that specifically examined the effectiveness of this process for deactivating nitrate salts. Cementation is also being assessed because of its prevalence as an immobilization method used for similar wastes at numerous facilities around the DOE complex, including at Los Alamos. The results of this Treatment Study Plan will be used to provide the basis for a Resource Conservation and Recovery Act (RCRA) permit modification request of the LANL Hazardous Waste Facility Permit for approval by the New Mexico Environment Department-Hazardous Waste Bureau (NMED-HWB) of the proposed treatment process and the associated facilities.

    With new treatments and novel technology available, personalized medicine has become an important piece in the new era of medical product development. Traditional statistics methods for personalized medicine and subgroup identification primarily focus on single treatment or two arm randomized control trials. Motivated by the recent development of outcome weighted learning framework, we propose an alternative algorithm to search treatment assignments which has a connection with subgroup identification problems. Our method focuses on applications from clinical trials to generate easy to interpret results. This framework is able to handle two or more than two treatments from both randomized control trials and observational studies. We implement our algorithm in C++ and connect it with R. Its performance is evaluated by simulations, and we apply our method to a dataset from a diabetes study. Copyright © 2016 John Wiley & Sons, Ltd. PMID:26892174

    Focus groups were conducted in 2005-2006 with 25 urban methadone-maintained outpatients to examine beliefs about the role of spirituality in addiction and its appropriateness in formal treatment. Thematic analyses suggested that spirituality and religious practices suffered in complex ways during active addiction, but went "hand in hand" with recovery. Participants agreed that integration of a voluntary spiritual discussion group into formal treatment would be preferable to currently available alternatives. One limitation was that all participants identified as strongly spiritual. Studies of more diverse samples will help guide the development and evaluation of spiritually based interventions in formal treatment. PMID:20025443

  14. Nature of DNA lesions induced in human hepatoma cells, human colonic cells and human embryonic lung fibroblasts by the antiretroviral drug 3'-azido-3'-deoxythymidine

    International Nuclear Information System (INIS)

    This study tried to clarify the question if nuclear genotoxicity played a role in 3'-azido-3'-deoxythymidine (AZT) toxicity. We investigated cytotoxic and DNA-damaging effects of AZT on human hepatoma HepG2 and human colonic CaCo-2 cells as well as on human diploid lung fibroblasts HEL. The amount of induced DNA damage was measured by standard alkaline single cell gel electrophoresis (SCGE). The nature of induced DNA lesions was evaluated (1) by modified SCGE, which includes treatment of lysed cells with DNA repair enzymes Endo III and Fpg and enables to recognize oxidized bases of DNA, and (2) by SCGE processed in parallel at pH 13.0 (standard technique) and pH 12.1, which enables to recognize alkali labile DNA lesions and direct DNA strand breaks. Cytotoxicity of AZT was evaluated by the trypan blue exclusion technique. Our findings showed that 3-h treatment of cells with AZT decreased the viability of all cell lines studied. SCGE performed in the presence of DNA repair enzymes proved that AZT induced oxidative lesions to DNA in all cell types. In hepatoma HepG2 cells and embryonic lung fibroblasts HEL the majority of AZT-induced DNA strand breaks were pH-independent, i.e. they were identified at both pH values (12.1 and 13.0). These DNA lesions represented direct DNA breaks. In colonic Caco-2 cells DNA lesions were converted to DNA strand breaks particularly under strong alkaline conditions (pH > 13.0), which is characteristic for alkali-labile sites of DNA. DNA strand break rejoining was investigated by the standard comet assay technique during 48 h of post-AZT-treatment in HepG2 and Caco-2 cells. The kinetics of DNA rejoining, considered an indicator of DNA repair, revealed that AZT-induced DNA breaks were repaired in both cell types slowly, though HepG2 cells seemed to be more repair proficient with respect to AZT-induced DNA lesions

    Numerous studies have shown that depression is highly familial and impairing and that a history of depression in a parent is the strongest risk factor for depression in a child. Many of the parents in these studies have never received sustained treatment despite histories of recurrent depression. None of the studies have examined the effects of maternal symptom remission on offspring symptom or functioning. We sought to determine the feasibility of treating depressed mothers who brought an offspring for the treatment of depression and to examine the relationship between improved maternal depression and symptomatic improvement and social functioning in their offspring. Nine mothers bringing their offspring for treatment of depression, and who were evaluated and found to be currently depressed, completed a 12-week open trial of interpersonal psychotherapy. Mothers and their depressed offspring were assessed by independent evaluators at weeks 0, 6, and 12 for depressive symptomatology and social functioning. Although the rates of depression were high among the mothers, few eligible mothers agreed to participate. Of the 12 who entered treatment, 9 (75%) completed it. Mothers and offspring improved with regard to depressive symptomatology and global functioning over the course of the trial. Improvement in maternal depression was significantly associated with improvement in offspring functioning but not symptom reduction. Improvement of maternal depression may be associated with improved outcomes in depressed offspring. However, it is difficult to engage depressed mothers in treatment for themselves if they come to the clinic to bring their child for treatment of depression. It may be more feasible to study the effect of improved maternal depression on offspring by sampling depressed mothers coming for their own treatment and then assessing their children over the course of maternal treatment.

    Micropollutants remain of concern in drinking water, and there is a broad interest in the ability of different treatment processes to remove these compounds. To gain a better understanding of treatment effectiveness for structurally diverse compounds and to be cost effective, it is necessary to select a small set of representative micropollutants for experimental studies. Unlike other approaches to-date, in this research micropollutants were systematically selected based solely on their physico-chemical and structural properties that are important in individual water treatment processes. This was accomplished by linking underlying principles of treatment processes such as coagulation/flocculation, oxidation, activated carbon adsorption, and membrane filtration to compound characteristics and corresponding molecular descriptors. A systematic statistical approach not commonly used in water treatment was then applied to a compound pool of 182 micropollutants (identified from the literature) and their relevant calculated molecular descriptors. Principal component analysis (PCA) was used to summarize the information residing in this large dataset. D-optimal onion design was then applied to the PCA results to select structurally representative compounds that could be used in experimental treatment studies. To demonstrate the applicability and flexibility of this selection approach, two sets of 22 representative micropollutants are presented. Compounds in the first set are representative when studying a range of water treatment processes (coagulation/flocculation, oxidation, activated carbon adsorption, and membrane filtration), whereas the second set shows representative compounds for ozonation and advanced oxidation studies. Overall, selected micropollutants in both lists are structurally diverse, have wide-ranging physico-chemical properties and cover a large spectrum of applications. The systematic compound selection approach presented here can also be adjusted to fit

    Full Text Available Abstract Background We investigated the treatments given, the outcome and the patient- and treatment-system dependent factors affecting treatment outcome in a national two-year cohort of culture-verified extra-pulmonary tuberculosis cases in Finland. Methods Medical records of all cases in 1995 - 1996 were abstracted to assess treatment and outcome, using the European recommendations for outcome monitoring. For risk factor analysis, outcome was divided into three groups: favourable, death and other unfavourable. Predictors of unfavourable outcome were assessed in univariate and multivariate analysis. Results In the study cohort of 276 cases, 116 (42.0% were men and 160 (58.0% women. The mean age was 65.7 years. A favourable outcome was achieved in 157/276 (56.9% cases, consisting of those cured (8.0% and treatment completed (48.9%. Death was the outcome in 17.4% (48/276 cases, including cases not treated. Other unfavourable outcomes took place in 45 (16.3% cases. Significant independent risk factors for death in multinomial logistic regression model were male sex, high age, immunosuppression, any other than a pulmonary specialty being responsible at the end of the treatment and other than standard combination of treatment. For other unfavourable treatment outcomes, significant risk factor was treatment with INH + RIF + EMB/SM. Deep site of TB was inversely associated with the risk of other unfavourable outcome. Conclusions The proportion of favourable outcome was far below the goal set by the WHO. Age and comorbidities, playing an important role in treatment success, are not available in routine outcome data. Therefore, comparisons between countries should be made in cohort analyses incorporating data on comorbidities.

  10. Study about the integrated treatment of chemical and radioactive effluents, introducing the zero release concept

    International Nuclear Information System (INIS)

    An Integrated System to the treatment of Chemical and Radioactive Effluents to the Centro Experimental Aramar is proposed and evaluated, introducing the Effluent Zero Release concept, where factors related to the environmental regulation in vigor in the country, as well as the availability of hydrological resources in the place where CEA have been implanted, are considered. Through a literature analysis of the main effluents treatment techniques available nowadays and after a case of study selection, take into account two industrial installations that will be implanted at CEA, it was defined an arrangement to compose the Integrated System to the Treatment of Chemicals and Radioactive Effluents, focusing the Zero Release concept consolidation. A defined arrangement uses a combination among three treatment processes, it means chemical precipitation, reverse osmosis and evaporation, that were experimentally evaluated. The proposed arrangement was evaluated using synthetic effluents, that were prepared based on data from literature and conception documents of the installation considered in this work. Three kinds of effluents were simulated, one arising from a nuclear reactor laundry, one arising from the water refrigeration system and demineralized water production to the nuclear reactor and the other one arising from a nuclear material production laboratory. Each effluent were individually submitted to the selected treatment processes, to get the best operational conditions for each treatment process. The results got during the laboratory assays show that the proposed Integrated System to the Treatment of Chemicals and Radioactive Effluents is feasible, consolidating the Effluent Zero Release concept, which is the proposition of this work.

    A patient with a cardiac ventricular assist device (VAD) with computer-controlled driver presented to our department for radiation therapy. The treatment plan was 4500 cGy to the rectum over 25 fractions with 15MV photon beams. All beams avoided the pump and leads. The response to electromagnetic interference (EMI) was evaluated by observing a duplicate driver in the treatment configuration as the patient's fields were delivered to a solid water equivalent phantom. Pretreatment dose assessment included calculations with Pinnacle treatment planning system, AAPM TG36 data analysis, and MOSFET measurements on the surface of the driver during the phantom irradiation. During the first patient treatment, MOSFETs were placed on the pump and leads, approximately 1cm from the left lateral treatment portal. No additional shielding was applied to the VAD. EMI was absent and the VAD operated normally during the pretreatment test and throughout the treatment course. Radiation to the driver was too low to be detected by the MOSFETS. Cumulative dose estimates to the pump were 425 cGy to 0.1cc (DVH), 368 cGy (TG36), and 158.5 cGy (MOSFET). MOSFET readings to the leads were 70.5 cGy. External beam radiation treatment was safely delivered to a VAD dependent patient. The VAD exhibited no adverse response to EMI and doses up to 425 cGy. Our results are based on one case and further study is encouraged. PMID:19020490

    Full Text Available Abstract Background Opioid addiction is a chronic, relapsing disease and remains a major public health challenge. Despite important expansions of access to conventional treatments, there are still significant proportions of affected individuals who remain outside the reach of the current treatment system and who contribute disproportionately to health care and criminal justice costs as well as to public disorder associated with drug addiction. The NAOMI study is a Phase III randomized clinical trial comparing injectable heroin maintenance to oral methadone. The study has ethics board approval at its Montréal and Vancouver sites, as well as from the University of Toronto, the New York Academy of Medicine and Johns Hopkins University. The main objective of the NAOMI Study is to determine whether the closely supervised provision of injectable, pharmaceutical-grade opioid agonist is more effective than methadone alone in recruiting, retaining, and benefiting chronic, opioid-dependent, injection drug users who are resistant to current standard treatment options. Methods The case study submitted chronicles the challenges of getting a heroin assisted treatment trial up and running in North America. It describes: a brief background on opioid addiction; current standard therapies for opioid addiction; why there is/was a need for a heroin assisted treatment trial; a description of heroin assisted treatment; the beginnings of creating the NAOMI study in North America; what is the NAOMI study; the science and politics of the NAOMI study; getting NAOMI started in Canada; various requirements and restrictions in getting the study up and running; recruitment into the study; working with the media; a status report on the study; and a brief conclusion from the authors' perspectives. Results and conclusion As this is a case study, there are no specific results or main findings listed. The case study focuses on: the background of the study; what it took to get

    Full Text Available Abstract The purpose of this review was to: (1 locate all exercise treatment studies of fibromyalgia (FM patients from 1988 through 2005, (2 present in tabular format the key details of each study and (3 to provide a summary and evaluation of each study for exercise and health outcomes researchers. Exercise intervention studies in FM were retrieved through Cochrane Collaboration Reviews and key word searches of the medical literature, conference proceedings and bibliographies. Studies were reviewed for inclusion using a standardized process. A table summarizing subject characteristics, exercise mode, timing, duration, frequency, intensity, attrition and outcome variables was developed. Results, conclusions and comments were made for each study. Forty-six exercise treatment studies were found with a total of 3035 subjects. The strongest evidence was in support of aerobic exercise a treatment prescription for fitness and symptom and improvement. In general, the greatest effect and lowest attrition occurred in exercise programs that were of lower intensity than those of higher intensity. Exercise is a crucial part of treatment for people with FM. Increased health and fitness, along with symptom reduction, can be expected with exercise that is of appropriate intensity, self-modified, and symptom-limited. Exercise and health outcomes researchers are encouraged to use the extant literature to develop effective health enhancing programs for people with FM and to target research to as yet understudied FM subpopulations, such as children, men, older adults, ethnic minorities and those with common comorbidities of osteoarthritis and obesity.

    Objective The aim of this study was to compare the consumption of dental treatment among patients with Crohn´s disease (CD) or ulcerative colitis (UC) compared to age and gender matched control groups. Design The study group comprised 2085 patients with CD and 3161 with UC from the Uppsala-Örebro region and from the Stockholm region. The patients in the cohort were diagnosed between 1960 and 1989. Patients up to 70 years of age were included in the study. The two patients groups were compared to age- and gender-matched, randomly selected control groups from the same geographic area comprising a corresponding number of participants. Results CD patients had significantly higher total number of procedures registered (p < 0.000). The difference was most pronounced for removable dentures (+65%), fillings in front teeth (+52%) and endodontic treatment (+46%) when Crohn’s patients were compared to controls (p<0.001). The corresponding figures for UC patients were also a significantly higher total number of procedures (p < 0.005), more clinical examinations (p<0.000), fillings in canines and incisors (p < 0.001) and fillings in bicuspids and molars (p < 0.000). Conclusion This study demonstrate that CD and UC individuals use more dental treatment compared to an age-gender matched control group, and more caries-related treatments. The difference was most pronounced for restorative treatment in patients with Crohn’s. PMID:26267797

    2015-07-01

    Griffith Edwards' proposal for the alcohol 'treatment versus advice' study--also known as 'the family study'--illustrates how ahead of his time he was. The sample consisted of 100 married men who attended with their wives for a comprehensive assessment. Those randomized to 'advice' were told that the responsibility for attaining the goal of abstinence lay in the patient's hands, supported by his wife, that no further intervention was indicated, but that the research social worker would 'keep a watching brief' by visiting the home every 4 weeks for 12 months. Across multiple outcome measures there was no evidence that 'treatment'--considerable in amount by modern standards--was better than advice. Conversely, marital variables such as wives' alcohol-related hardship were significantly predictive of the outcome of the drinking problem. The study was arguably one of the principal sources of the whole 'brief treatments'/'brief interventions' movement which gathered momentum from then on and which, arguably, has itself become the conventional wisdom. The findings questioned the very nature of the addiction change process, suggesting that non-specific factors might be the more important, an issue that still remains unresolved. It is less clear that the study has left such a mark in terms of the development of a family and social model of addiction treatment and change. For example, it continues to be a struggle to help treatment organizations to become more family-inclusive. PMID:26042559

    Polystyrene (PS) films are used in packaging and biomedical applications because of their transparency and good environmental properties. The present investigation is centered on the antifungal and antibacterial activities involved in the film surface. Subsequently, microbial formations were immobilized on the modified PS films. Living microorganisms such as bacteria and yeast were used. Untreated PS films show very fast rate of growth of bacteria within few hours. The study involves developments of polymer surfaces with bacterial growth and further studies after giving antibacterial treatment such as plasma treatment. Major emphasis has been given to study the effect of various parameters which can affect the performance of the improved material. Films were prepared by two methods: plasma treatment under vacuum and under ongoing He-Ne laser source. The parameters such as (1) surface area by contact angle measurements, (2) quality of material before and after treatment by SEM and FTIR spectra and (3) material characterization by UV-vis spectra were studied.

    Aim to breed new orchid varieties adapted to climate of Vietnam for domestic use and export, national orchid breeding program has been established for some years. In our study, application of induced mutation by using 60Co. gamma ray treatment was set up to breed new varieties of Phalaenopsis orchid. Different dosages of 60Co. gamma rays were 0, 20, 40, 60, 100 Gy doses with dose rate of 90 Gy/h. Three years after radiation treatment, result showed that the use of 60Co. gamma rays for treatment had conspicuously influenced to growth, mutation frequencies in morphological and physiological traits of Phalaenopsis varieties. Survival rate and growth vigor of treated plants reduced while total variation ratio increased by higher doses. The useful variations were the highest in 20 Gy and next to 40 Gy radiation treatments. In this study, LD50 dose in radiation treatment for Phalaenopsis orchid variety was at dose 40 Gy. Suitable doses in radiation treatment which made wide diversity for Phalaenopsis orchid was at doses 20-40 Gy. At present, selected Phalaenopsis lines are being conducted to research segregating mutated traits, mutation frequencies in inbred Phalaenopsis lines and multiplication of promising mutant lines.

    Somatostatin analogs (SSAs), including lanreotide, play a fundamental role in treatment of neuroendocrine tumors (NETs) of the gastrointestinal tract. SSAs control the clinical symptoms and are the treatment of choice in functioning NETs. Data indicating that SSAs have anti-proliferative activity has mainly come from prospective or retrospective observational studies. A recently published CLARINET study confirmed the anti-proliferative effect of lanreotide in a much broader range of NET patients than previously reported. As a result, it is now possible for clinicians to use lanreotide to treat patients with well-differentiated metastatic grade 1 and grade 2 GEP NETs (i.e., with a Ki-67 proliferative index CLARINET study also challenge the current "wait and watch" strategy for NET treatment. Instead, it is proposed that SSAs are considered at an early stage of NET management, as already suggested by many organizations and scientific societies. PMID:26793016

    Many authors have suggested adapting treatment programs to the specific needs of sexual abusers. However, little research has been conducted to understand what these patients seek in therapy or what elements play a key role in keeping them in treatment. In this pilot study, fifteen (N=15) pedophile sexual abusers from La Macaza clinic for sexual abusers were interviewed. Plan analysis was used to investigate the most prevalent components involved in staying in or leaving therapy. Results suggest that many components involved in the plans leading to doing and to avoiding treatment were similar. Differences were found in regards to the outcome of confrontations with the therapists, a tendency to isolate and overcomply, guilt related to the abuse, a need for a stable environment, and a need to be accepted. These results are discussed along with possible ways to improve the patients' involvement in treatment. PMID:15851510

The manual was based on cognitive-behavioral therapy, short-term strategic family therapy, solution-focused therapy, and motivational interviewing. Treatment response was reported by the patients, their mothers, and the therapists. The patients reported moderate (but statistically non-significant) improvement from pre- to post-treatment. The mothers, however, reported large effects and statistically significant improvement from pre- to post-treatment. The therapists reported marked or moderate treatment response in six of the 12 patients. The ratings of change by mothers converged well with the views of change of both the patients and therapists, whereas the convergence of views on change between the two latter sources was far lower.

    The present survey studies, in a group of 145 alcoholics from the National Institute on Alcoholism in Costa Rica, the effectiveness of four therapeutic orientations in alcoholism: behavioral, psychosocial, occupational and multiple. The survey was carried out in a harmless population of alcoholics, and it aims to work out and to test treatment designs suitable to the uncovered level or prevention respecting to alcoholism, the secondary one. Each one of the groups receiving the diverse treatments stayed as in-patient under similar conditions. The treatment had a two-week duration; once finished, the patient was discharged and continued with a one-year follow-up. The outcomes are the following: 1. Treatment. The occupational and behavior-oriented treatments present a five months abstinence period as an estimate average effectiveness. The psychosocial-oriented treatments reach a seven months abstinence period. Its major effectiveness is due to the specific action this orientation develops on the patients having the worst prognosis. The integration, in a treatment, of orientations corresponding to different theoretical frames can determine reciprocal inhibition phenomena among orientations and lower the general effectiveness level. 2. Diagnosis. The personalities defined as depressive and paranoiac according to their prevailing basic anxiety, and the presence or absence of a conjugal tie holds an estimate link with the abstinence the patient showed when he was discharged from treatment. The prognosis value of this characteristic disappears when it is then direct object of a therapeutic orientation (psychosocial) given that this characteristics are sensitive to changes by action in a specific treatment.

    Cannabis is the most commonly used illicit substance worldwide, and cannabis use disorders (CUDs) are correspondingly high. Increased demand for treatment and relatively low rates of positive clinical outcomes has led to a large scientific investment in the development of interventions for the treatment of CUD. Much of this research is conducted with cannabis users who are not seeking treatment at the time of study participation, and it is unknown whether these individuals are representative of those who seek treatment. This study contrasted samples of cannabis users participating in screening interviews for treatment and nontreatment research studies. Several differences between groups emerged: Treatment-seekers were more likely to be female (43% vs. 29%), older (33.4 vs. 29.7 years), and have longer cannabis use histories compared with non-treatment-seekers (p = .007). Treatment-seekers were more likely to report experiencing guilt after using cannabis and to feel that cannabis use has been a problem for them. Additionally, treatment-seekers reported a greater mean number of reasons for making a quit attempt, experiencing a greater number of withdrawal symptoms, and employing more coping strategies during prior quit attempts. Despite the aforementioned differences, the 2 groups were similar on several key characteristics, particularly with regards to current levels of cannabis use and related problems. PMID:25150537

    Objective: To confirm the clinical therapeutic effects of acupuncture and moxibustion on Bell's palsy.Methods: 480 cases from 4 hospitals were enrolled for this study, among whom 439 cases completed the whole course of the study. The patients were randomly divided into the following 3 groups, a control group(treated with prednisone, vitamin B1, vitamin B12 and dibazol), an acu-moxibustion group (treated with filiform needle plus moxibustion), and a basic treatment plus acu-moxibustion group (treated with oral medicine like those in the control group plus acupuncture, and with moxibustion like in the acu-moxibustion group). The whole treatment course lasted 4 weeks. The therapeutic effects were evaluated according to the symptoms and signs, House-Brackmann grading scale and facial disability indexes(FDI). Results: All the 4 centers (hospitals) completed this study well, with no statistically significant difference found among the 4 centers in therapeutic effects. The patients with different conditions were well distributed in the 3 groups, thus the basic general data were comparable (P>0.05).The therapeutic effects of the two treatment groups were better than the control group (respectively P<0.05 and P<0.01), and it was the best in the acu-moxibustion group (P<0.01). Conclusion:Acupuncture and moxibustion may exert definite therapeutic effects on Bell's palsy, better than that of the basic treatment group or the basic treatment plus acu-moxibustion group.

    Hepatocellular carcinoma (HCC) is the fifth most frequent cancer worldwide with high morbidity, mortality and increasing incidence. It is of note that the main curative therapies for HCC are hepatic resection and transplantation although the majority of patients at the time of presentation are not eligible for resection or orthotopic liver transplantation (OLT) due to the underlying cirrhosis. Currently, a variety of loco-regional therapies, including radiofrequency ablation (RFA), percutaneous ethanol injection (PEI), microwave coagulation therapy (MCT), transarterial chemoembolization (TACE) and others, have been developed as alternative treatment options for HCC. Among these techniques, RFA is currently the most widely used treatment, due to its several advantages, such as safety and efficacy. To date, the effectiveness of RFA for HCC is reduced by the presence of residual tumor as a consequence of insufficient treatment. In order to ameliorate the effects of RFA on HCC, several in vivo studies, have been performed on its application as single or in combination treatment with drugs or others loco-regional therapies, by using rabbit VX2 liver model. This represents an ideal model of liver cancers and is widely used for imaging and other experimental studies due to the rapid growth of these tumors and their similarity to human hepatocellular carcinoma. In order to elucidate the therapeutic potential of RFA with adjuvant treatments for HCC, we reviewed the latest findings on the RFA-based studies in rabbit VX2 hepatocarcinoma models. PMID:27525037

    Full Text Available Aim: Catatonia is caused by a variety of psychiatric and organic conditions. The onset, clinical profile, and response to treatment may vary depending on the underlying cause. The study is an attempt to explore clinical profile, possible etiological correlates with neurotic/psychotic spectrum illnesses, and response to treatment and outcome in patients of catatonia. Materials and Methods: Retrospective chart analysis by using semistructured data sheet for the analysis of sociodemographic data, clinical profile, precipitating event, and response to treatment in patients with catatonic symptoms admitted to IHBAS (Institute of Human Behaviour and Allied Sciences, New Delhi, India from January 2009 to December 2010 was undertaken. Results: Catatonia was commonly observed in patients with the following profile - late twenties, female, Hindu religion, urban background, and housewives. Psychotic spectrum disorder (57%, N=35 was the most commonly entertained diagnosis and affective disorder (18%, N=11 being the second common. Thirty four percent of the subjects responded to lorazepam treatment and rest required modified electroconvulsive therapy (MECT. Conclusion: Catatonia is more likely to be associated with Schizophrenia and Other Psychotic Disorders in Indian settings. Majority of patients responded to therapy either by lorazepam alone or to its augmentation with modified ECT. The study being a retrospective one, the sample being representative of the treatment seeking group only, and unavailability of the follow up data were the limitations of the study

    Full Text Available AIMS: 1. To verify the sensibility of panic patients to a mixture of 35% CO2 and 65% O2. 2. To determine if a ten days treatment with clonazepam attenuates the panic attacks induced by the inhalation of 35% carbon dioxide in panic disorder. METHOD: We randomly selected six panic disorder subjects, using the Structured Clinical Interview for DSM-IV. All subjects went double-blindly through an inhalation of 35% CO2 and compressed gas (atmospheric air on two occasions. First, at baseline, when they were drug free. Second, after a 10 days clonazepam treatment. RESULTS: Neither at baseline nor after treatment any patient had a panic attack during compressed gas inhalation. At the first test five patients (83.3% had a severe panic attack with high levels of subjective anxiety during carbon dioxide inhalation. After 9.6 (± 3.4 days of clonazepam treatment, only two (33.3% patients experienced a mild panic attack. CONCLUSION: This pilot study suggests the efficacy of the short term clonazepam therapy in attenuating panic attacks and supports the usefulness of the 35% carbon dioxide challenge test as an analogue method for study the efficacy of anti-panic drugs. Further placebo-controlled studies to pharmacological treatment are warranted.

    This 1-group, 4-week observational study aimed to (1) assess the feasibility of recruiting, retention, and completion of a 4-week auricular point acupressure (APA) treatment protocol for chronic pain in adult patients and (2) assess the effects of APA in pain reduction (pain severity and pain interference) among these patients. The participants received a 4-week APA treatment protocol in weekly cycles. Each weekly cycle included 5 days with APA seeds taped onto the ear and 2 days without. Each participant was called every day to monitor adherence to the treatment protocol (the actual times the participant pressed the seeds each day and the duration of applied pressure), to answer analgesic use, and to answer the pain intensity questionnaire. Thirty participants were initially enrolled in this study, but 5 did not continue. The retention rate was 83% (n = 25). Approximately 60% of the participants (n = 15) adhered to the 4-week APA and completed all data assessments. At baseline assessment, only 40% of all participants (n = 12 of 30) were confident that APA would reduce and eliminate pain; nonetheless, all participants reported fewer episodes of pain occurrences and pain intensity with the APA treatment. For the participants who completed the 4-week APA protocol (n = 15), 96% (n = 14) decreased analgesic medication intake and 88% (n = 13) felt "much better" after the APA treatment. Participants reported an average reduction of 63% in the worst pain intensity at day 7. By the end of the 4-week APA protocol, an even greater reduction in pain intensity was reported (66%, n = 10, at day 28). The participants who did not complete the treatment protocol reported an average pain reduction of 29%, which fluctuated to 22% before they dropped out. Auricular point acupressure is feasible for patients with chronic pain. The preliminary findings of this feasibility study show a reduction in pain intensity and improvement in physical function, which demonstrate the potential for

    Purpose: To conduct a study of the structure and process of treatment planning in the United States. Methods and Materials: A Patterns of Care treatment planning consensus committee developed a survey form that was used to gather data for 106 items relating to the structure and process of treatment planning. These questions were general in nature and not specific to any particular disease site. Seventy-three facilities were randomly selected for site visits from the 1321 radiation therapy facilities in the United States: 21 academic, 26 hospital, and 26 free-standing. During the site visit the facility physicist, assisted by the site-visit physicist, completed the form. Results: Twenty-nine percent of facilities have cobalt-60 machines; 25% have 4 MV linacs; 75% have photon energies in the range of 5-8 MV; and less than 10% have energies greater than 20 MV. Academic facilities led hospital and free-standing facilities by about 30 percentage points in the availability of all electron energies (88 vs. 58%, approximately, in the range 4-13 MeV and scaling downward to about 60 vs. 30% at the highest energies). The national averages for the availability of Cs-137, Ir-192, and I-125 were 87, 73, and 44%, respectively. Computerized tomography (CT) scanning is not available or not used in 15% of hospital and free-standing facilities. Ninety-six percent of facilities have treatment planning computers; at 10% of facilities physicians do not participate in treatment planning. The estimated national averages of facilities having formal quality assurance (QA) programs for treatment planning systems, simulators, film processors, and blocking systems are 44, 79, 62, and 55%, respectively. Sixty-three percent of facilities obtain independent machine calibrations. Conclusion: This is the first patterns of treatment planning study carried out in the United States and the results reported here will establish a baseline for future studies.

  9. Case studies of the high voltage electron beam technology for wastewater treatment

    International Nuclear Information System (INIS)

    The development of innovative technologies for the remediation of contaminated sites is continually being considered as a treatment option for several reasons. From an economic standpoint, the treatment costs of conventional technologies continues to increase and from an environmental impact view, treatment technologies are sought that destroy contaminants without creating additional disposal problems. The high energy electron beam process has been shown to be effective in destroying many organic compounds associated with contaminated sites. The experiments to date have been conducted at both bench and full scale. Bench scale studies are performed using a 5000 Curie 60Co-y source whereas full scale studies have been completed at a pilot facility that has a daily capacity of 170,000 gallons (120 gallons per minute, gpm). The application of this technology to problems that face EPA could result in cost effective treatment of contaminated groundwater, soils, sediments and sludges, as well as demilitarization (chemical weapons), and as an industrial treatment unit process. To provide open-quotes on-siteclose quotes treatability/feasibility studies as well as small scale clean-ups we have now developed a mobile system. This system is capable of treating up to 50 gpm, employing a 500 kV, 40 mA accelerator. The system is self contained and can be used in remote locations if necessary. We have received an US Environmental Protection Agency, SITE Emerging Technology project which has as its focus the application of this process to complex mixtures of contaminants in groundwater, wastewater, soils, sediments, and sludges. This paper will discuss the details of several case studies conducted at full scale using the mobile treatment process and review data obtained from on-going studies that have direct benefit to EPA and may assist groups within the environmental clean-up field to more effectively accomplish their mission

    2013-07-01

    The forward-shift prevention and treatment strategy is the current trend of the development of clinical medicine. As hypertension is an important risk factor for cardiovascular diseases, it is curtail to pay attention to the prevention and treatment of prehypertension. Pre-hypertension refers to the blood pressure value between the normal blood pressure and high blood pressure, which easily develops into hypertension with complications. In recent years, pre-hypertension has attracted attentions both at home and abroad. The traditional Chinese medicinal theory of "preventive treatment of disease" shows its unique advantages in preventing and treating pre-hypertension and high blood pressure. With the socio-economic development and the changes in lifestyle, traditional pathogenetic theories have no longer kept pace with the occurrence regularity of modern high blood pressure and pre-hypertension. Therefore, the in-depth study on the pathogenesis of pre-hypertension is of great significance in the guidance of clinical prevention and treatment. It is believed that the etiologies of pre-hypertension are related to improper diet, sedentariness and emotional instability. In other words, stasis in six forms such as qi stagnation, dyspepsia, damp obstruction, phlegm stasis, blood stasis and fire stagnation is an crucial pathogenesis of pre-hypertension. Consequently, on the basis of the traditional Chinese medicinal theory of "preventive treatment of disease", the combination of the treatment based on syndrome differentiation and the correspondence of prescriptions and the syndromes in treating pre-hypertension is worth clinically promoting and applying.

    2011-01-01

    Full Text Available Abstract Background We investigate methods used to analyse the results of clinical trials with survival outcomes in which some patients switch from their allocated treatment to another trial treatment. These included simple methods which are commonly used in medical literature and may be subject to selection bias if patients switching are not typical of the population as a whole. Methods which attempt to adjust the estimated treatment effect, either through adjustment to the hazard ratio or via accelerated failure time models, were also considered. A simulation study was conducted to assess the performance of each method in a number of different scenarios. Results 16 different scenarios were identified which differed by the proportion of patients switching, underlying prognosis of switchers and the size of true treatment effect. 1000 datasets were simulated for each of these and all methods applied. Selection bias was observed in simple methods when the difference in survival between switchers and non-switchers were large. A number of methods, particularly the AFT method of Branson and Whitehead were found to give less biased estimates of the true treatment effect in these situations. Conclusions Simple methods are often not appropriate to deal with treatment switching. Alternative approaches such as the Branson & Whitehead method to adjust for switching should be considered.

  13. Treatment delay of bone tumours, compilation of a sociodemographic risk profile: A retrospective study

    International Nuclear Information System (INIS)

    Bone tumours are comparatively rare tumours and delays in diagnosis and treatment are common. The purpose of this study was to analyse sociodemographic risk factors for bone tumour patients in order to identify those at risk of prolonged patients delay (time span from first symptoms to consultation), professional delay (from consultation to treatment) or symptom interval (from first symptoms to treatment). Understanding these relationships might enable us to shorten time to diagnosis and therapy. We carried out a retrospective analysis of 265 patients with bone tumours documenting sociodemographic factors, patient delay, professional delay and symptom interval. A multivariate explorative Cox model was performed for each delay. Female gender was associated with a prolonged patient delay. Age under 30 years and rural living predisposes to a prolonged professional delay and symptom interval. Early diagnosis and prompt treatment are required for successful management of most bone tumour patients. We succeeded in identifying the histology independent risk factors of age under 30 years and rural habitation for treatment delay in bone tumour patients. Knowing about the existence of these risk groups age under 30 years and female gender could help the physician to diagnose bone tumours earlier. The causes for the treatment delays of patients living in a rural area have to be investigated further. If the delay initiates in the lower education of rural general physicians, further training about bone tumours might advance early detection. Hence the outcome of patients with bone tumours could be improved

    2016-04-01

    Context • Frequent binge eating is often a symptom of an underlying eating disorder, such as bulimia nervosa (BN) or binge eating disorder (BED). The role of homeopathy in the treatment of binge eating remains poorly explored. Objective • The study intended to measure the efficacy of individualized homeopathic treatment for binge eating in adult males. Design • This case study was a 9-wk pilot using an embedded, mixed-methods design. A 3-wk baseline period was followed by a 6-wk treatment period. Setting • The setting was the Homeopathic Health Clinic at the University of Johannesburg in Johannesburg, South Africa. Participants • Through purposive sampling, the research team recruited 15 Caucasian, male participants, aged 18-45 y, who were exhibiting binge eating. Intervention • Individualized homeopathic remedies were prescribed to each participant. Primary Outcome Measures • Participants were assessed by means of (1) a self-assessment calendar (SAC), recording the frequency and intensity of binging; (2) the Binge Eating Scale (BES), a psychometric evaluation of severity; and (3) case analysis evaluating changes with time. Results • Ten participants completed the study. The study found a statistically significant improvement with regard to the BES (P = .003) and the SAC (P = .006), with a large effect size, indicating that a decrease occurred in the severity and frequency of binging behavior during the study period. Conclusions • This small study showed the potential benefits of individualized homeopathic treatment of binge eating in males, decreasing both the frequency and severity of binging episodes. Follow-up studies are recommended to explore this treatment modality as a complementary therapeutic option in eating disorders characterized by binge eating. PMID:27089525

    Pancreatic survival is one of the worst in oncology. To what extent wait times affect outcomes in unknown No population-based study has previously explored patient and treatment delays among individuals with pancreatic cancer. The aim of this study was to estimate patient and treatment delays in patients with pancreatic cancer and to measure their association with survival in a nonselected population. All patients diagnosed with pancreatic cancer for the first time between 2009 and 2011 and registered in two French digestive cancer registries were included. Patient delay (time from onset of symptoms until the first consultation categorized into <1 or ≥1 month), and treatment delay (time between the first consultation and treatment categorized into less or more than 29 days, the median time) were collected. Overall delay was used to test associations between survival and the timeliness of care by combining patient delay and treatment delay. Patient delay was longer than 1 month in 46% of patients. A patient delay longer than one month was associated with the absence of jaundice (p < 0.001) and the presence of metastasis (p = 0.003). After adjusting for other covariates, such as symptoms and treatment, the presence of metastasis was negatively associated with treatment delay longer than 29 days (p = 0.025). After adjustment for other covariates, especially metastatic dissemination and the result of the resection, overall delay was not significantly associated with prognosis. We found little evidence to suggest that timely care was associated with the survival of patients. PMID:27130333

    Full Text Available Background Thalassemia is a common public health problem in Malaysia and one of the most common chronic and genetic disorders. Aims The present qualitative study explores knowledge about thalassemia, perceptions about conventional therapies and the points that affect Malaysian patients with thalassemia in taking medications correctly. Methods This study used a qualitative method. Purposive and theoretical samplings were combined to explore the issues related to thalassaemia and its perceptions. Twenty-one patients with thalassemia were recruited from the Thalassemia Society, Kedah, Malaysia from July to October 2015. The semi-structured interviews were audio taped, transcribed verbatim and translated into English for thematic content analysis. Results Participants perceived thalassemia as an incurable disease which is due to genetic and blood related disorders. A positive perception was shown towards conventional therapies considering it as effective for their condition. High treatment cost was given as a reason why patients perceived conventional therapies as effective. Fear of side effects was the main reason the patients gave for their delay in looking for treatment. However, due to limited treatment options, patients were reported to show positive attitude towards the side effects due to thalassemia treatment. Conclusion This explanatory investigation suggests that thalassemia patients’ understanding about thalassemia is complex in nature. The findings may help healthcare providers remove myths about the fear of the treatment. It may also help in improving patient’s compliance towards the thalassemia therapies. Main focus for future research should be on those patients who declined the conventional therapies.

    Full Text Available The role of hyperbaric oxygen therapy (HBOT in the treatment of acute ischemic stroke is controversial. This prospective study assessed the efficacy and safety of HBOT as adjuvant treatment on 46 acute ischemic stroke in patients who did not receive thrombolytic therapy. The HBOT group (n=16 received conventional medical treatment with 10 sessions of adjunctive HBOT within 3–5 days after stroke onset, while the control group (n=30 received the same treatment but without HBOT. Early (around two weeks after onset and late (one month after onset outcomes (National Institutes of Health Stroke Scale, NIHSS scores and efficacy (changes of NIHSS scores of HBOT were evaluated. The baseline clinical characteristics were similar in both groups. Both early and late outcomes of the HBOT group showed significant difference (P≤0.001. In the control group, there was only significant difference in early outcome (P=0.004. For early efficacy, there was no difference when comparing changes of NIHSS scores between the two groups (P=0.140 but there was statistically significant difference when comparing changes of NIHSS scores at one month (P≤0.001. The HBOT used in this study may be effective for patients with acute ischemic stroke and is a safe and harmless adjunctive treatment.

    Between 30 and 50% of MS patients may prematurely discontinue disease modifying therapies. Little research has examined how to best talk with patients who have discontinued treatment against medical advice. The aim of this pilot study was to determine whether telephone counseling increases disease modifying therapy (DMT) re-initiation among nonadherent patients with multiple sclerosis (MS). Participants were eligible if they had relapsing-remitting disease, had stopped taking a DMT, and had no plan to re-initiate treatment despite a provider recommendation. Following a baseline assessment, 81 patients were randomly assigned to either five 20 min, weekly sessions of Motivational Interviewing/Cognitive Behavioral Therapy (MI-CBT) or Treatment as Usual (TAU) with brief education. At 10 weeks, patients initially assigned to TAU switched over to MI-CBT. Compared to patients in the TAU group, patients undergoing MI-CBT were significantly more likely to indicate they were re-initiating DMT (41.7 vs. 14.3%). These significant results were replicated among patients crossing over from TAU to MI-CBT. Treatment satisfaction was high, with 97% of participants reporting that they would recommend MI-CBT to other patients with MS. Results of this pilot study provide initial support for the use of MI-CBT among MS patients who have discontinued treatment against medical advice.Clinicaltrials.gov: NCT01925690. PMID:26563147

  4. Results of the A-01 Wetland Treatment System Confirmation Study, June-September 1999; FINAL

    International Nuclear Information System (INIS)

    A wetland treatment system (WTS) is being considered to reduce metal concentrations and remove toxicity in effluent from the A-01 NPDES outfall. In order to evaluate the removal efficiency of the treatment system, a pilot scale WTS was constructed and operated for three months, using the same hydrosoils, wetland vegetation, and retention time that would be used in a full-scale treatment system. Early results from the pilot study indicate that toxicity was removed and that metal concentrations were reduced but that copper and mercury concentrations still usually exceeded regulatory limits. During the last three weeks of the study, it was determined that the soils probably did not have adequate levels of sulfur and organic carbon. The system was amended with sulfur (as calcium sulfate) and organic material. Metals removal was greatly enhanced subsequent to the soil amendments. Although the pilot scale WTS has not had adequate time to develop, with respect to plant growth and hydrosoil chemistry, the data indicate that a WTS will remove toxicity and will substantially reduce metal concentrations of the effluent. Certain concerns remain to be addressed, however. Concentrations of mercury in the outflow from the treatment cells are still above the current NPDES limit, but performance is improving. Additionally, while the overall performance of the system demonstrates a clear elimination of toxicity, one of the four sets of cells is not performing acceptably with respect to toxicity removal. Continued monitoring and adjustment of the wetland treatment cells will be performed to further enhance the performance of the system

    Transcranial magnetic stimulation (TMS) is a non-invasive surgery-free tool used to stimulate the brain by time-varying magnetic fields. TMS is currently being investigated as a treatment for neurological disorders such as depression, Parkinson's disease and TBI. Before moving to human TMS/TBI trials, animal testing should be pursued to determine suitability and adverse effects. As an initial study, four healthy mice were treated with TMS at different power levels to determine short-term behavioral effects and set a control group baseline. The mouse's behavior was studied using the Rotorod test, which measures the animal's latency to fall off a rotating rod, and the Versamax test, which measures horizontal and vertical movement, and total distance traveled. The Rotorod test has shown for TMS power levels >=90% the mice begin to fall directly post-treatment. Similarly, the Versamax test has shown for power levels >=80% the mice are less mobile directly post-treatment. Versamax mobility was found to return to normal the day following treatment. These mice were housed in the facility for 4 months and the behavioral tests were repeated. Versamax results showed there was no significant variation in mobility indicating there are no long-term side effects of TMS treatment on the mice.

    Full Text Available Abstract Background Fatigue is a major problem of cancer patients. Thirty percent of cancer survivors report serious fatigue three years after finishing treatment. There is evidence that physical exercise during cancer treatment reduces fatigue. This may also lead to an improvement of quality of life. Such findings may result in a decrease of healthcare related expenditures and societal costs due to sick leave. However, no studies are known that investigated these hypotheses. Therefore, the primary aim of our study is to assess the effect of exercise during cancer treatment on reducing complaints of fatigue and on reducing health service utilisation and sick leave. Methods/Design The Physical Activity during Cancer Treatment study is a multicentre randomised controlled trial in 150 breast and 150 colon cancer patients undergoing cancer treatment. Participants will be randomised to an exercise or a control group. In addition to the usual care, the exercise group will participate in an 18-week supervised group exercise programme. The control group will be asked to maintain their habitual physical activity pattern. Study endpoints will be assessed after 18 weeks (short term and after 9 months (long term. Validated questionnaires will be used. Primary outcome: fatigue (Multidimensional Fatigue Inventory and Fatigue Quality List and cost-effectiveness, health service utilisation and sick leave.

Chart review data of 102 subjects regarding demographics, medications, comorbidities, concomitant medications and domains of functional impairment were collected, and predictors were assessed using a binominal logistical regression model. One hundred and two patients (78.4 % male) with a mean age of 28.8 (SD = 9.8, range = 18-55) years were enrolled in the study. Childhood diagnosis of ADHD, agents used for treatment (MPH or atomoxetine), individual domains of dysfunction and use of additional psychotropic drugs were not found to be related to treatment adherence. Patients with a university education and those referred for family history of ADHD were more likely to adhere to treatment (p = 0.05 and 0.03, respectively). On the other hand, reasons for referral other than ADHD were significantly more frequently related to non-adherence (p = 0.02). Treatment noncompliance remains a significant problem despite therapeutic effects of medications. Identification of predictors of non-adherence can lead to heightened awareness of special populations at risk. We have found that prior awareness on ADHD (via past history/media/friends) leading to self/clinician referral to rule out ADHD and pervasiveness of symptoms across functional domains led to better compliance in our sample. Future research with prospective design utilizing objective tools for adherence is required. PMID:27056071

    The risperidone maintenance treatment in schizophrenia study was designed to identify the duration of maintenance treatment required with an initial therapeutic dose in contrast to reducing the dose over time. This study investigated extrapyramidal symptoms (EPSs) in different risperidone maintenance treatment paradigms over 1 year. Clinically stabilized patients with schizophrenia (n = 374) were randomized to a no-dose-reduction group and 4-week and 26-week reduction groups, in which the dose was gradually reduced by 50% over 8 weeks and maintained. Extrapyramidal symptoms were assessed at baseline and monthly for 6 months, followed by every 2 months. The Simpson-Angus Scale of Extrapyramidal Symptoms-Chinese version assessed EPS severity. Data were analyzed by a generalized linear mixed model (GLMM). The frequency of EPS at baseline was 23.2%, 20.0%, and 21.3% in the 4-week, 26-week, and no-dose-reduction groups, respectively. Risperidone dosage, positive symptoms, and disorganized thoughts at baseline predicted development of EPS. The GLMM indicated that a significant decrease in EPS was maintained, and different trajectories occurred over time across groups. In the 235 patients who continued treatment after 1 year, the incidence of EPS decreased to 4.1%, 2.8%, and 10.0% in the 4-week, 26-week, and no-dose-reduction groups, respectively, whereas the numbers of dropouts because of intolerable EPS were not significantly different (4.8%, 6.7%, and 6.2%, respectively). These novel findings indicate EPSs were tolerable and differentially decreased depending on the dose paradigm during the 1-year treatment period. Future studies should implement a GLMM to investigate antipsychotic adverse effects during long-term treatment. PMID:26848792

    This study is a test of the so-called subversion hypothesis, which posits that mentally disordered persons who commit minor offenses are prosecuted primarily for the purpose of imposing mental health treatment on them through evaluation and treatment for incompetency to stand trial. These persons, according to the subversion hypothesis, find themselves in the criminal process because they do not meet the stringent civil commitment standards, but do meet the less stringent criteria for a disorderly conduct prosecution. The findings, based on 893 disorderly conduct prosecutions in a single jurisdiction over a two-year period, do not lend general support to the subversion hypothesis. PMID:8889132

    Control of clarifier in the activated sludge process is critical for ensuring effective wastewater treatment. This paper is to study appropriate control strategies for a clarifier in an industrial wastewater treatment plant. Five control strategies are proposed, implemented and evaluated in a simulation software (West ++ ). The sludge blanket height and the effluent suspended solids concentration were proposed as the measured variable. The manipulated variable was the quantity of polymer added to the system. The strategies were evaluated in terms of their ability to maintain the sludge blanket height below 1.5m, their polymer requirements, their sensitivity to poor tuning and the required control action.

    2012-09-01

    Full Text Available Abstract Background Proximal humerus fracture is the third most common fracture type after hip and distal radius fracture in elderly patients. A comprehensive study by Palvanen et al. demonstrated an increase in the annual fracture rate of 13.7% per year over the past 33 years. Should this trend continue, the fracture rate would triple over the next three decades. The increasing incidence of low-energy fractures raises questions about the optimal treatment in terms of functional outcome, pain, and rehabilitation time, as well as the economical impact. Despite the high incidence and costs of proximal humerus fractures, there is currently no valid scientific evidence for the best treatment method. Several publications, including a Cochrane review outline the need for high-quality, well-designed randomized controlled trials. Methods/Design The study is a prospective, randomized, national multi-center trial. The hypothesis of the trial is that surgical treatment of displaced proximal humerus fractures achieves better functional outcome, pain relief, and patient satisfaction compared to conservative treatment. The trial is designed to compare conservative and surgical treatment of proximal humerus fractures in patients 60 years and older. The trial includes two strata. Stratum I compares surgical treatment with locking plates to conservative treatment for two-part fractures. Stratum II compares multi-fragmented fractures, including three- and four-part fractures. The aim of Stratum II is to compare conservative treatment, surgical treatment with the Philos locking plate, and hemiarthroplasty with an Epoca prosthesis. The primary outcome measure will be the Disabilities of the Arm, Shoulder and Hand (DASH score and the secondary outcome measures will be the EuroQol-5D (EQ-5D value, OSS, Constant-Murley Score, VAS, and 15D. Recruiting time will be 3 years. The results will be analyzed after the 2-year follow-up period. Discussion This publication

    Light therapy (LT) has been widely used in the treatment of seasonal affective disorder. Recently some evidence indicated that LT may play a role in bipolar depression, either as monotherapy or in combination with total sleep deprivation (TSD). However, the studies examining the treatment effect of LT in bipolar depression resulted in inconsistent findings. To clarify the role of LT in the disorder, we conducted a meta-analysis to compare the efficacy of LT in the treatment of bipolar depression. The results of individual studies were synthesized by a random effects model. Nine studies including 489 patients with bipolar depression were included in this current meta-analysis. We found that disease severity was significantly decreased after LT, in both with and without TSD, and with concomitant medication (pdepression. However, the detailed mechanism of LT still remains elusive. Further well-designed controlled trials are required to investigate the optimal intensity and frequency of LT in the treatment of bipolar depression. PMID:26993616

  20. Graft irradiation in the treatment of acute rejection of renal transplants: a randomized study

    International Nuclear Information System (INIS)

    A randomized study of graft irradiation in the treatment of acute rejection of renal transplants was conducted from 1978 to 1981. Patients developing clinical signs of an acute graft rejection received customary antirejection treatment in the form of intravenous administration of high-dose (1 gm per day) of methylprednisolone. They were at the same time randomized to either receive therapeutic irradiation (175 rad every other day to a total of 525 rad) or sham irradiation. Neither the patient nor the Transplant Service surgeons knew at any time whether the radiation treatment had been given. Eighty-three rejection episodes occurring in 64 grafts were entered into the study. Acute rejection was reversed in 84.5% of grafts in the control and 75% in the treated group. The incidence of recurrent rejection was higher in the treated group (66 vs. 46%) and graft survival was lower (22% vs. 54%). The study failed to demonstrate a beneficial effect of graft irradiation in the treatment of acute renal allograft rejection, when used in conjunction with high dose steriods
