    3'-Azido-3'-deoxythymidine (AZT) is the first clinically effective drug for the treatment of human immunodeficiency virus infection. The drug interaction with human serum albumin (HSA) has been an important component in understanding its mechanism of action, especially in drug distribution and in drug-drug interaction on HSA in the case of multi-drug therapy. We present here crystal structures of a ternary HSA-Myr-AZT complex and a quaternary HSA-Myr-AZT-SAL complex (Myr, myristate; SAL, salicylic acid). From this study, a new drug binding subsite on HSA Sudlow site 1 was identified. The presence of fatty acid is needed for the creation of this subsite due to fatty acid induced conformational changes of HSA. Thus, the Sudlow site 1 of HSA can be divided into three non-overlapped subsites: a SAL subsite, an indomethacin subsite and an AZT subsite. Binding of a drug to HSA often influences simultaneous binding of other drugs. From the HSA-Myr-AZT-SAL complex structure, we observed the coexistence of two drugs (AZT and SAL) in Sudlow site 1 and the competition between these two drugs in subdomain IB. These results provide new structural information on HSA-drug interaction and drug-drug interaction on HSA.

    The purpose of this report was to present findings from a pilot study conducted to explore the associations between sociodemographic, drug use, and health belief factors and perceived compliance with zidovudine (AZT) among African-American drug users. Data were collected in Washington, DC, USA from individuals who were African-American; were recent or current drug injectors or crack smokers; were HIV-seropositive, and were receiving treatment for HIV infection. Participants were recruited through local organizations that provide services to HIV-infected persons. Participants were interviewed using a questionnaire that solicited sociodemographic, lifetime and current drug use, current sexual behaviours, health status, HIV and drug treatment history, and health belief data. Analyses were limited to individuals currently using an illicit substance and who had received AZT during their medical treatment. Parametric (Pearson's r) and nonparametric (Spearman's rho) statistics were used to assess correlations between perceived compliance with AZT dosing and independent variables. As the study was intended to be both descriptive and exploratory, the level of statistical significance was set at 0.10, rather than the customary 0.05. Antiretroviral medications recognized and recalled by participants are presented. The most commonly recalled medication was AZT. Slightly less than one-third of participants reported being completely compliant with an AZT regimen. Perceived compliance was found to be negatively associated with 5 variables: age, homelessness, number of injections in the previous 30 days, trading sex for drugs, and the perception that AIDS is no longer a serious disease since the development of new antiretroviral medications. Intensity of feelings of joy, fear, and the belief that taking more anti-HIV medications would result in better health were found to be positively correlated. Bivariate associations between perceived compliance and sociodemographic, drug use

    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

    Full Text Available Azidothymidine (AZT is a synthetic, chain-terminating nucleoside analog used to treat HIV-1 infection. While AZT is not actively transported across the blood brain barrier, it does accumulate at high levels in cerebrospinal fluid, and subsequently diffuses into the overlying parenchyma. Due to the close anatomical proximity of the neurogenic niches to the ventricular system, we hypothesize that diffusion from CSF exposes neural stem/progenitor cells and their progeny to biologically relevant levels of AZT sufficient to perturb normal cell functions. We employed in vitro and in vivo models of mouse neurogenesis in order to assess the effects of AZT on developing and adult neurogenesis. Using in vitro assays we show that AZT reduces the population expansion potential of neural stem/progenitor cells by inducing senescence. Additionally, in a model of in vitro neurogenesis AZT severely attenuates neuroblast production. These effects are mirrored in vivo by clinically-relevant animal models. We show that in utero AZT exposure perturbs both population expansion and neurogenesis among neural stem/progenitor cells. Additionally, a short-term AZT regimen in adult mice suppresses subependymal zone neurogenesis. These data reveal novel negative effects of AZT on neural stem cell biology. Given that the sequelae of HIV infection often include neurologic deficits –subsumed under AIDS Dementia Complex (Brew, 1999 - it is important to determine to what extent AZT negatively affects neurological function in ways that contribute to, or exacerbate, ADC in order to avoid attributing iatrogenic drug effects to the underlying disease process, and thereby skewing the risk/benefit analysis of AZT therapy.

    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.

  9. Parameterization of AZT-A widely used nucleoside inhibitor of HIV-1 reverse transcriptase

    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.

  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.

    Bacterial ATP-binding cassette (ABC) transporters of transition metals are essential for acquisition of necessary elements from the environment. A large number of Gram-negative bacteria, including human pathogens, have a fourth conserved gene of unknown function adjacent to the canonical permease, ATPase, and solute-binding protein (SBP) genes of the AztABC zinc transporter system. To assess the function of this putative accessory factor (AztD) from Paracoccus denitrificans, we have analyzed its transcriptional regulation, metal binding properties, and interaction with the SBP (AztC). Transcription of the aztD gene is significantly up-regulated under conditions of zinc starvation. Recombinantly expressed AztD purifies with slightly substoichiometric zinc from the periplasm of Escherichia coli and is capable of binding up to three zinc ions with high affinity. Size exclusion chromatography and a simple intrinsic fluorescence assay were used to determine that AztD as isolated is able to transfer bound zinc nearly quantitatively to apo-AztC. Transfer occurs through a direct, associative mechanism that prevents loss of metal to the solvent. These results indicate that AztD is a zinc chaperone to AztC and likely functions to maintain zinc homeostasis through interaction with the AztABC system. This work extends our understanding of periplasmic zinc trafficking and the function of chaperones in this process.

  16. 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. In terms of ΔHm, the samples presented an average value of 31.12 kJ mol-1.A determinação da pureza química, a faixa de fusão e a variação de entalpia envolvida no processo de caracterização de fármacos é um dos principais requisitos avaliados no controle de qualidade em indústrias farmacêuticas.

    Full Text Available Zidovudine-loaded solid lipid nanoparticles (AZT-SLNs and zidovudine in solution were prepared and administered in rats. The aim of this research was to study whether the bioavailability of zidovudine can be improved by AZT-SLNs perorally to rats as compared to oral administration of zidovudine. Zidovudine was determined in plasma and tissues by reverse phase high performance liquid chromatography. The pharmacokinetic parameters of zidovudine were determined after peroral administration: area under curve of concentration versus time (AUC for AZT-SLNs was 31.25% greater than AZT solution; meanwhile mean resident time (MRT was found to be 1.83 times higher for AZT-SLNs than AZT solution. Elimination half life of zidovudine was also increased for SLN formulation. Tissue distribution pattern of zidovudine was changed in case of AZT-SLNs. AUC of zidovudine in brain and liver was found to be approximately 2.73 and 1.77 times higher in AZT-SLNs than AZT solution, respectively, indicating that AZT-SLNs could cross blood brain barrier. Distribution of zidovudine was approximately 0.95 and 0.86 times lesser in heart and kidney, respectively. It can be concluded from the study that oral administration of AZT-SLNs modifies the plasma pharmacokinetic parameters and biodistribution of zidovudine.

    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

    Two new coordination compounds [Zn(AZT)4(H2O)2](PA)2·4H2O and [Zn(AZT)2(H2O)4](HTNR)2·4H2O have been prepared by using AZT(3-azido-1,2,4-triazole)as ligands,PA-(picrate)or HTNR-(anion formed by the deprotonation of one of the two hydroxyl-groups of 2,4,6-trinitroresorcinol)as outer anions.The X-ray crystallographic data show that the central zinc(Ⅱ)ion is coordinated by four N atoms of four AZT molecules and two O atoms of two H2O molecules in [Zn(AZT)4(H2O)2](PA)2·4H2O.In [Zn(AZT)2(H2O)4](HTNR)2·4H2O,six coordination-atoms come from two N atoms of two AZT molecules and four O atoms of four H2O molecules.The coordina-tion sites of AZT ligands in both compounds are always 4-N atoms of the triazole rings.H2O molecules play vital roles in the formation of hydrogen bonds,which contribute to the construction of the crystal structures of both compounds.The offset face-to-face π-π stacking interactions existing in the crystal of [Zn(AZT)4(H2O)2](PA)2·4H2O also contribute to the formation and stability of its crystal structure.TG-DTG and DSC analysis results show that the thermal decomposition processes of [Zn(AZT)2(H2O)4](HTNR)2·4H2O are milder than those of [Zn-(AZT)4(H2O)2](PA)2·4H2O due to the more coordination H2O molecules and less AZT ligands in the molecular unit of the former compound.Sensitivity tests reveal that [Zn(AZT)4(H2O)2](PA)2·4H2O has sensitive nature towards heat,whereas [Zn(AZT)2(H2O)4](HTNR)2·4H2O is insensitive;both compounds are insensitive to friction and im-pact.

    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

    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.

    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.

    Transition metal-transporting P{sub 1B}-type CPx ATPases play crucial roles in mediating metal homeostasis and resistance in all cells. The degree to which N-terminal metal binding domains (MBDs) confer metal specificity to the transporter is unclear. We show that the two MBDs of the Zn/Cd/Pb effluxing pump Anabaena AztA are functionally nonequivalent, but only with respect to zinc resistance. Inactivation of the a-MBD largely abrogates resistance to high intracellular Zn(II) levels, whereas inactivation of the b-MBD is not as deleterious. In contrast, inactivation of either the a- or b-MBD has little measurable impact on Cd(II) and Pb(II) resistance. The membrane proximal b-MBD binds Zn(II) with a higher affinity than the distal N-terminal a-MBD. Facile Zn(II)-specific intermolecular transfer from the a-MBD to the higher-affinity b-MBD is readily observed by {sup 1}H-{sup 15}N HSQC spectroscopy. Unlike Zn(II), Cd(II) and Pb(II) form saturated 1:1 S{sub 4} or S{sub 3}(O/N) complexes with AztA{sup aHbH}, where a single metal ion bridges the two MBDs. We propose that the tandem MBDs enhance Zn(II)-specific transport, while stabilizing a non-native inter-MBD Cd/Pb cross-linked structure that is a poor substrate and/or regulator for the transporter.

    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, Na{sub 7}(PO{sub 4}){sub 2}F{center_dot}19H{sub 2}O. 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-SiO{sub 2}-H{sub 2}O system. Acidic treatment of Hanford B-202 sludge with 1 M, 3 M, and 6 M HNO{sub 3} 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 Abstract Background Previous studies have assessed the validity of the observational study design by comparing results of studies using this design to results from randomized controlled trials. The present study examined design features of observational studies that could have influenced these comparisons. Methods To find at least 4 observational studies that evaluated the same treatment, we reviewed meta-analyses comparing observational studies and randomized controlled trials for the assessment of medical treatments. Details critical for interpretation of these studies were abstracted and analyzed qualitatively. Results Individual articles reviewed included 61 observational studies that assessed 10 treatment comparisons evaluated in two studies comparing randomized controlled trials and observational studies. The majority of studies did not report the following information: details of primary and ancillary treatments, outcome definitions, length of follow-up, inclusion/exclusion criteria, patient characteristics relevant to prognosis or treatment response, or assessment of possible confounding. When information was reported, variations in treatment specifics, outcome definition or confounding were identified as possible causes of differences between observational studies and randomized controlled trials, and of heterogeneity in observational studies. Conclusion Reporting of observational studies of medical treatments was often inadequate to compare study designs or allow other meaningful interpretation of results. All observational studies should report details of treatment, outcome assessment, patient characteristics, and confounding assessment.

    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.

  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

    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.

    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

    In this issue, Molecular Cancer Therapeutics inaugurates a new feature-The Cutting Edge: Spotlight on Clinical Response-whose objective is the rapid publication of breaking discoveries regarding target- or mechanism-based clinical responses in cancer. Targeted molecules are poised to alter the landscape of clinical cancer treatment. For example, because they can distinguish cancer cells from their normal counterparts, agents such as imatinib mesylate, a Bcr-Abl and Kit kinase inhibitor, can result in remarkable responses with minimal host toxicity in patients suffering from diseases characterized by abnormalities in the targeted kinases. Indeed, studies of imatinib mesylate in early-stage chronic myelogenous leukemia, whose hallmark is the aberrant Bcr-Abl, show response rates of more than 90%. Furthermore, gastrointestinal stromal tumors (GIST), a notoriously chemotherapy-refractory sarcoma, characterized by activating Kit kinase mutations, can show dramatic metabolic responses within days after initiation of treatment. With the wealth of new knowledge in this field, and numerous novel targeted molecules entering clinical trials, the above examples are likely to represent the tip of the iceberg. Indeed, in this issue, a paper by Senzer et al. documents, for the first time, successful use of adenoviral p53 therapy to treat a tumor in a patient with Li Fraumeni Syndrome, a hereditary cancer syndrome caused by the mutation of the p53 tumor suppressor gene. Some of the features of this response, such as the early disappearance of metabolic activity on fluorodeoxyglucose-positron emission tomography scans, are reminiscent of those of GIST responses to imatinib. These findings have important implications for patients with this syndrome, who are prone to develop numerous tumors and often succumb at a young age. In addition, because mutations in p53 are one of the more common aberrations in cancer in general, identification of these mutations and exploration of this

    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.

    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.

    A randomized, controlled clinical trial was started in the pre-HAART era to compare the efficacy of zidovudine (AZT) and interferon-alpha (IFN-α) either alone or in combination to reduce HIV viremia, maintain CD4+ cell count, and decrease time to AIDS progression and death. The purpose of the current study was to compare the effects of AZT and IFN on HIV load using modern technology. One hundred and eighty patients with CD4+ counts above 500 cells/mm3 were randomized to receive AZT alone, IFN-α alone, or AZT and IFN-α in combination. CD4+ cell count and HIV load at baseline and at the last follow-up visit were compared, and time to AIDS or death was calculated by treatment group. At a mean follow-up of 45 weeks, the mean change in log HIV RNA was −0.06 for the AZT alone group, −0.47 for the AZT plus IFN-α group (P = 0.01 versus AZT group), and −0.35 for the IFN-α alone group (P = 0.02 versus AZT group). There was no significant difference among groups in change in total CD4+ count or in time to AIDS or death. Since treatment with IFN-α produces significant decreases in HIV load, additional studies of IFN-α as part of a combination regimen are warranted. PMID:20235638

    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.

  3. Integrated thermal treatment systems study. Internal review panel report

    International Nuclear Information System (INIS)

    The U.S. Department of Energy (DOE) Office of Technology Development (OTD) commissioned two studies to evaluate nineteen thermal treatment technologies for treatment of DOE mixed low-level waste. These studies were called the Integrated Thermal Treatment System (ITTS) Phase I and Phase II. With the help of the DOE Office of Environmental Management (EM) Mixed Waste Focus Group, OTD formed an ITTS Internal Review Panel to review and comment on the ITTS studies. This Panel was composed of scientists and engineers from throughout the DOE complex, the U.S. Environmental Protection Agency, the California EPA, and private experts. The Panel met from November 15-18, 1994 to review the ITTS studies and to make recommendations on the most promising thermal treatment systems for DOE mixed low-level wastes and on research and development necessary to prove the performance of the technologies. This report describes the findings and presents the recommendations of the Panel

  4. Commentary on the multimodal treatment study of children with ADHD.

    Science.gov (United States)

    Barkley, R A

    2000-12-01

    The multimodal treatment study of attention deficit hyperactivity disorder (MTA Study) constitutes a landmark in the history of treatment research in child psychopathology, being the largest single study of its kind ever undertaken. Important findings have emerged from this project, as the papers in the present volume will attest. This commentary focuses on several concerns about the assumptions that appear to have guided the design of the MTA study, particularly its psychosocial treatment component, as well as the manner in which treatment results have been presented to date. In particular, no explicit theory of ADHD appears to have guided the construction of the treatment components, relying instead on implicit theories associated with those treatments, such as the notion that the symptoms of ADHD arise through faulty learning and defective contingencies of reinforcement. Future articles from this study will need to address these and other concerns if the results of the study are to be properly interpreted and the scientific and clinical yield is to be maximized.

    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.

    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.

    Full Text Available Purpose: The aim of the work was to assess bioactive properties and corrosion resistance of nickel titanium alloyafter alkali treatment and spark oxidation in Hank’s Balance Salt Solution.Design/methodology/approach: Surfaces of samples were prepared by chemical treatment in NaOHfollowed by heat treatment, and spark oxidation. 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

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

    This paper presents preliminary results of a financial viability study for the implementation of gamma radiation technology on a slaughterhouse wastewater treatment industry. Five scenarios were studied, including the current practice, representing different types of treatments and goals, e.g.: water reuse and/or sludge add value as agriculture fertilizers. Cost-benefit analysis, including the net present value (NPV) of each scenario, was used as a technique to compare the relative value of various strategies. Taking in account that the initial investment is amortized after 20 years, the implementation of Co-60 treatment with 20% water reuse and sludge application as agriculture fertilizers represents the most profitable project with the highest NPV. Therefore, the implementation of gamma radiation technology on a slaughterhouse wastewater treatment industry is not only technically viable as well as economically feasible. (author)

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.

    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)

    Takahashi, Daishi; Takahashi, Tomoya; Sone, Kazuya; Fukumoto, Ichiro

    Cryosurgical system utilizing liquid nitrogen and argon gas as cryogens has been used for the treatment of malignant tumors. Those devices fail to cool the tissues to the low temperatures that completely destroy the bulky tumors. It is of course difficult for the low power cooling devices using Peltier effect, to destroy the large tumors. Therefore adjunctive treatment such as hyperthermia treatment is needed to intensify the tissue destruction. Actually, hyperthermia has been clinically used to destroy tumors, but it is unclear that the hyperthermia enhances the tissue injury in cryosurgery because there have been few studies of the combination use of hyperthermia and cryosurgery. The purposes of this study are to produce the cryosurgery-hyperthermia treatment system utilizing Peltier device and Stirling cooler and to evaluate the effects of hyperthermia treatment immediately after thawing in cryosurgery onto the living normal liver tissue of mouse. In the no-load running test of our system, the minimum temperature of the cryoprobe reached -74.0 degrees C in 30 minutes. The findings of the stained tissues suggested that the combination treatment of both was effective to destroy the tissue and the higher temperature applied immediately after freezing and thawing in cryosurgery might reinforce the tissue destruction.

    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

    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

    2013-11-01

    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.

    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

MATERIALS AND METHODS: Male Wistar albino rats were randomly divided into 5 groups of 10 rats each: (1 nonligated, water; (2 ligated, water; (3 ligated, 1 mg/kg AZT; (4 ligated, 5 mg/kg AZT; and (5 ligated, 10 mg/kg AZT. All groups were treated with saline or AZT for 10 days. Periodontal tissues were analyzed by histopathology and immunohistochemical detection of MMP-2, MMP-9, COX-2, RANKL, RANK, OPG, and cathepsin K. Levels of IL-1β, IL-10, TNF-α, myeloperoxidase (MPO, and glutathione (GSH were determined by ELISA. RESULTS: Treatment with 5 mg/kg AZT resulted in reduced MPO (p<0.05 and IL-1β (p<0.05, increased levels of IL-10 (p<0.05, and reduced expression of MMP-2, MMP-9, COX-2, RANK, RANKL, cathepsin K, and increased expression of OPG. CONCLUSIONS: These findings reveal that AZT increases anti-inflammatory cytokines and GSH and decreases bone loss in ligature-induced periodontitis in rats.

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

    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.

    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.

  9. 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).

  11. Study on Control of Brain Temperature for Brain Hypothermia Treatment

    Science.gov (United States)

    Gaohua, Lu; Wakamatsu, Hidetoshi

    The brain hypothermia treatment is an attractive therapy for the neurologist because of its neuroprotection in hypoxic-ischemic encephalopathy patients. The present paper deals with the possibility of controlling the brain and other viscera in different temperatures from the viewpoint of system control. It is theoretically attempted to realize the special brain hypothermia treatment to cool only the head but to warm the body by using the simple apparatus such as the cooling cap, muffler and warming blanket. For this purpose, a biothermal system concerning the temperature difference between the brain and the other thoracico-abdominal viscus is synthesized from the biothermal model of hypothermic patient. The output controllability and the asymptotic stability of the system are examined on the basis of its structure. Then, the maximum temperature difference to be realized is shown dependent on the temperature range of the apparatus and also on the maximum gain determined from the coefficient matrices A, B and C of the biothermal system. Its theoretical analysis shows the realization of difference of about 2.5°C, if there is absolutely no constraint of the temperatures of the cooling cap, muffler and blanket. It is, however, physically unavailable. Those are shown by simulation example of the optimal brain temperature regulation using a standard adult database. It is thus concluded that the surface cooling and warming apparatus do no make it possible to realize the special brain hypothermia treatment, because the brain temperature cannot be cooled lower than those of other viscera in an appropriate temperature environment. This study shows that the ever-proposed good method of clinical treatment is in principle impossible in the actual brain hypothermia treatment.

    2010-04-01

    There are current concerns about the presence of persistent chemicals in recharge water used in soil aquifer treatment systems. Triclocarban (TCC) has been reported as a persistent, high production volume chemical with the potential to bioaccumulate in the environment. 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.

    This paper summarizes studies on the water treatment by adsorption, as for the adsorption during water treatment, reactivation of activated charcoal, and clarification of heating process. Reactivation of activated charcoal for the water treatment is carried out through drying in the heating furnace. Basic problems are the recovery degree of adsorption performance of reactivated activated charcoal and the recovery yield. Behavior of the activated charcoal in the heating reactivation furnace is divided into three stages including drying process, heating process, and gasification process. Among these processes, behaviors of organic matters during heating process are described. Thermogravimetric analyses (TGA) were conducted for activated charcoals adsorbing various organic matters in aqueous solutions. Three types of organic matters were classified from the TGA pattern, i.e., organic matters with relatively low boiling point (type-I), organic matters with higher boiling point (type-II), and phenol and lignin (type-III). Organic matters belonging to type-I and type-II are desorbed or decomposed, to be disappeared. Effectiveness of alkali cleaning is suggested for the type-III organic matters. 3 refs., 5 figs.

  17. Study of wastewater treatment plants efficiency using radiotracers

    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)

    Purpose: Adaptive radiation therapy for prostate cancer using online reoptimization provides an improved control of interfractional anatomy variations. However, the clinical implementation of online reoptimization is currently limited by the low efficiency of current strategies and the difficulties associated with integration into the current treatment planning system. This study investigates the strategies for performing fast (∼2 min) automatic online reoptimization with a clinical fluence-map-based treatment planning system; and explores the performance with different input parameters settings: dose-volume histogram (DVH) objective settings, starting stage, and iteration number (in the context of real time planning).Methods: Simulated treatments of 10 patients were reoptimized daily for the first week of treatment (5 fractions) using 12 different combinations of optimization strategies. Options for objective settings included guideline-based RTOG objectives, patient-specific objectives based on anatomy on the planning CT, and daily-CBCT anatomy-based objectives adapted from planning CT objectives. Options for starting stages involved starting reoptimization with and without the original plan's fluence map. Options for iteration numbers were 50 and 100. The adapted plans were then analyzed by statistical modeling, and compared both in terms of dosimetry and delivery efficiency.Results: All online reoptimized plans were finished within ∼2 min with excellent coverage and conformity to the daily target. The three input parameters, i.e., DVH objectives, starting stage, and iteration number, contributed to the outcome of optimization nearly independently. Patient-specific objectives generally provided better OAR sparing compared to guideline-based objectives. The benefit in high-dose sparing from incorporating daily anatomy into objective settings was positively correlated with the relative change in OAR volumes from planning CT to daily CBCT.

Methods We conducted an open-label pilot randomized clinical trial study in 43 Thai children with CD4 15 to 24% of starting generic AZT/3TC/NVP immediately (Arm 1 or deferring until CD4 Results Recruitment took 15 months. Twenty-six of 69 (37.7% were not eligible due mainly to low CD4%. Twenty four and 19 were randomized to arms 1 and 2 respectively. All accepted the randomized arm; however, 3 in arm 1 stopped ART and 1 in arm 2 refused to start ART. Ten/19 (53% in arm 2 started ART. At baseline, median age was 4.8 yrs, CDC A:B were 36:7, median CD4 was 19% and viral load was 4.8 log. All in arm 1 and 17/19 in arm 2 completed the study (median of 134 weeks. No one had AIDS or death. Four in immediate arm had tuberculosis. Once started on ART, deferred arm children achieved similar CD4 and viral load response as the immediate arm. Adverse events were similar between arms. The deferred arm had a 26% ART saving. Conclusion Almost 40% of children were not eligible due mainly to low CD4% but adherence to randomized treatment and retention in trial were excellent. A larger study to evaluate when to start ART is feasible.

    2006-01-01

    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.

    This feasibility study will investigate the opportunities, restrictions and cost impact to refurbish the existing Radioactive Liquid Waste Treatment Plant (RLWTP) while utilizing the same basic criteria that was used in the development of the new Radioactive Liquid Waste Treatment Facility (RLWTF). The objective of this study is to perform a more in-depth analysis of refurbishing the existing than has been done in the past so as to provide a basis for comparison between refurbishing the existing or constructing a new. The existing plant is located at Technical Area 50 (TA-50) within the Los Alamos National Laboratory (LANL). The initial structure was built in 1963. Over the ensuing years, the building has been modified and several additions have been constructed. In 1966, laboratories, ion exchange and pretreatment functions were added. The decontamination and decommissioning activities and ventilation equipment were added in 1984. The following assumptions are the basic parameters considered in the development of a design concept to refurbish the RLWTP: (1) Allow continued operation of the during retrofit construction. (2) Design the necessary expansion within the site constraints. (3) Satisfy National Pollutant Discharge Elimination System (NPDES) and National Emission Standards for Hazardous Air Pollutants (NESHAPS) permit conditions and other environmental regulations. (4) Comply with present DOE Orders and building code requirements. The refurbishment concept is a phased demolition and construction process

    Respiratory tract infections are an important health problem because of high incidence and economic costs. The World Health Organization identifies honey as a potential demulcent treatment for cough. The aim of this study is to determine: i) patient public perceptions towards a proposed randomized controlled trial (RCT) comparing the effects of honey to placebo for treatment of cough in children; ii) potential participation rates for proposed trial; iii) whether age and gender of parent or child impacts on proposed cough assessment tools. Forty adult participants with children age 1-6 years presenting with an upper respiratory tract infection were enrolled. They underwent a structured interview regarding the proposed trial and assessed their child's cough using two validated questionnaires. Eighty-eight percent of those recruited were willing to participate in the proposed trial. The two independently validated cough scores correlated well. A relationship between age and gender of child or parent with cough assessment score was not found. We conclude that a RCT to determine the effects of honey versus placebo is feasible. The public find the outcome measures and trial design acceptable. PMID:23904963

    In this study, the effect of simultaneous plasma treatment and thermal annealing on the diffusion of Ag in low and high-density polyethylene (LDPE and HDPE) and on intermixing at the metal/polymer interface is examined. Metal layers were deposited onto 50 {mu}m thick LDPE and HDPE foils using diode sputtering. Concentration profiles of Ag were determined by Rutherford backscattering spectrometry (RBS). Ag diffusion coefficients in LDPE and HDPE were extracted from measured Ag depth profiles. Diffusion coefficients 5.05 x 10{sup -14}-6.78 x 10{sup -14} cm{sup 2}.s{sup -1} and 2.44 x 10{sup -14}-4.66 x 10{sup -14} cm{sup 2}.s{sup -1} were found for Ag in HDPE and Ag in LDPE, respectively. Morphology changes after the plasma treatment were determined using atomic force microscopy (AFM) and from RBS measurements as well. Surface fraction of Ag and plasma induced surface chemistry modification was investigated using XPS analysis. The signal of Ag bonded on polymer structure was identified and degradation of polymer substrate was observed in XPS spectra. (copyright 2008 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

    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

    The aim of this study was to evaluate the clinical, laboratory findings and therapeutic features of patients with brucellosis. The diagnosis was made by clinical findings, automated blood culture, serology (Rose Bengal plate agglutination test, standard tube agglutination (Wright) and immunofluorerescence). The susceptibility of 13 strains was tested in vitro. The base sequence was determined for four strains. Forty-five cases were collected (31 acute and 14 sub-acute). Contamination was digestive in 62%. Symptoms of patients were fever (93%), sweating (82%), arthralgia (78%) and splenomegaly (51%). Elevated erythrocyte sedimentation rate was determined in 80%, leukopenia in 49% and anaemia in 37% of cases. Blood cultures were positives in 39% of cases. The four sequenced strains were identified as Brucella melitensis biovar abortus. Six strains were resistant to sufomethoxazol-trimetoprim (54%). In 93% of cases, the treatment was associated rifampicin and doxycyclin. One patient died. No relapse was reported. PMID:18387752

    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).

    Some antipsychotics, including amisulpride, have shown to be effective in the treatment of various painful conditions, lessening pain as well as symptoms of anxiety and/or depression. In this open-label, 12-week study, we explored the efficacy and tolerability of amisulpride in patients with fibromyalgia. We recruited 40 patients, 1 male and 39 females, aged 46.2 ± 6.8 years, who met the ACR criteria for fibromyalgia and had a score equal to or greater than 4 in the pain severity item of the Fibromyalgia Impact Questionnaire (FIQ). Amisulpride was added to their current treatment regimen at an initial dose of 25 mg/day and titrated according to the clinical response and tolerability (mean final dose, 87.5 ± 41.3 mg/day). In the intent-to-treat analysis (i.e., all recruited patients), using a baseline-observation-carried-forward approach, the mean score in the FIQ decreased from 75.7 ± 10.6 to 73.2 ± 15.4, but this change was not statistically significant. Pain severity, as measured with the visual analogue scale from the FIQ, remained unchanged. Nonsignificant improvements were observed in depressive or anxiety symptoms using the Beck Depression Inventory and the State-Trait Anxiety Inventory, respectively. Twenty-six patients either withdrew from the study, mainly due to adverse reactions, or were lost to follow-up (n = 11, 27.5 %, for each category). Despite its promising results in some chronic painful conditions and in a related illness, such as chronic fatigue syndrome, amisulpride does not seem to provide any benefit to patients with fibromyalgia. Amisulpride was poorly tolerated by our participants.

    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%.

    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

    Full Text Available Background/Aim. Acromioclavicular (AC luxations most often affect athletes. The published results regarding the treatment of AC joint luxations vary. Each method has its advantages and disadvantages, so there is still no consensus on the best method of treatment. The aim of this study was to review the results of a number of surgical approaches to stabilization of AC joint recorded over the span of five years. Methods. This study was based on the data acquired from the analysis of 28 patients with AC luxation surgically treated in the Clinical Center of Montenegro. One group of 16 patients underwent the traditional AO method (with transfixation of AC joint with Kirschner wire and Zuggurtung tension bands or the Bosworth method (using the coracoclaviculartransfixation screw - Zugg-Bosw group. The second group of 12 patients underwent a newer techinque with the Hook plate (Hook plate group. Results. All the patients had AC luxation of higher degree, stage IV-VI acording to the Rockwood scale. The average age of the two groups was very similar, with 28 being the average age of the Zugg-Bosw group, and 25 of the Hook plate group. Most patients were males (82%, injured mostly during athletic activity (75%-83%. Complications were more common and more complex in the Zugg-Bosw group, with 2 early and 8 late comlications. There are only 3 late complications in the Hook plate group, but with no significant statistical difference (p = 0.19; t = -1.34; df = 27. With respect to the subjective patient satisfaction following the treatment, the Hook plate group gave significantly better evaluations (4.4 ± 0.19(p = 0.007; t = 2.95; df = 27.

    Although the initiation of antiretroviral therapy (ART) has promoted the reconstitution of CD4+ T-cell count in the HIV infected population, not all patients can achieve the normalization of their immunologic functions. We analysed the variables associated with immunologic recovery, which is commonly regarded as the increase of CD4 to 350 cell/μL after a year of ART. We collected data from 3,485 patients attending a university-based HIV clinic from June 2005 to July 2014 in Shanghai, China. Logistic regression test was performed to analyse the risk factors for suboptimal CD4+ recovery following yearlong ART. The CD4+ T-cell of 723 participants (41.5% of the 1744 subjects) showed more than 350 cell/μL after one year of ART. Compared with baseline CD4 > 350 cell/μL, patients with baseline CD4 ≤ 200 cell/μL or 200 < CD4 ≤ 350 cell/μL were 42.6, 4.5 times more likely to be incomplete CD4 recovery, respectively. The risk of suboptimal immunologic recovery among patients with regimen including AZT or d4T were 2.1, 2.4 times higher compared with TDF, respectively. In our study, between optimal CD4 recovery group and suboptimal recovery group, there were no significant differences in age, gender, marital status, transmission routes, WHO stage, and CD4 recovery rates. As for the dynamic CD4 change, we found the CD4 recovery rates were 49.9% and 61.8% in the second and third year of ART, respectively. Patients who had a low level of CD4+ T-cell count (< 200 cell/μL) during the initiation of ART exhibited more difficulties recovering to a normal level. Furthermore, the regimen, including AZT or d4T, was not beneficial to CD4 recovery. So, more efforts should be made to guarantee the early diagnosis and timely treatment for HIV/AIDS patients, and simultaneously optimize antiretroviral therapy. PMID:26559026

    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.

  11. 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)

  12. 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.

    Full Text Available Background. Obese individuals who suffer from major depressive disorder are routinely screened out of weight loss trials. Treatments targeting obesity and depression concurrently have not been tested. Purpose. To test the short-term efficacy of a treatment that combined behavioral weight management and cognitive behavioral therapy (CBT for obese adults with depression. Methods. Twelve obese females diagnosed with major depressive disorder received weekly group behavioral weight management, combined with CBT for depression, for 16 weeks. Weight, symptoms of depression, and cardiovascular disease (CVD risk factors were measured at baseline and week 16. Results. Participants lost 11.4% of initial weight and achieved significant improvements in symptoms of depression and CVD risk factors. Conclusions. Obese individuals suffering from major depressive disorder can lose weight and achieve improvements in symptoms of depression and CVD risk factors with 16 weeks of combined treatment. A larger randomized controlled trial is needed to establish the efficacy of this treatment.

  16. Endovascular Treatment of Thoracic Aortic Dissection: Hemodynamic Shear Stress Study

    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

  19. Does carbon reduction increase sustainability? A study in wastewater treatment.

    Sweetapple, Christine; Fu, Guangtao; Butler, David

    2015-12-15

    This study investigates the relationships between carbon reduction and sustainability in the context of wastewater treatment, focussing on the impacts of control adjustments, and demonstrates that reducing energy use and/or increasing energy recovery to reduce net energy can be detrimental to sustainability. Factorial sampling is used to derive 315 control options, containing two different control strategies and a range of sludge wastage flow rates and dissolved oxygen setpoints, for evaluation. For each, sustainability indicators including operational costs, net energy and multiple environmental performance measures are calculated. This enables identification of trade-offs between different components of sustainability which must be considered before implementing energy reduction measures. In particular, it is found that the impacts of energy reduction measures on sludge production and nitrogen removal must be considered, as these are worsened in the lowest energy solutions. It also demonstrates that a sufficiently large range of indicators need to be assessed to capture trade-offs present within the environmental component of sustainability. This is because no solutions provided a move towards sustainability with respect to every indicator. Lastly, it is highlighted that improving the energy balance (as may be considered an approach to achieving carbon reduction) is not a reliable means of reducing total greenhouse gas emissions.

    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.

    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

    New therapeutic strategies are needed to combat the emergence of infections due to multidrug-resistant Neisseria gonorrhoeae. In this study, fosfomycin (FOS) was tested against 89 N. gonorrhoeae isolates using the Etest method, showing MIC50/MIC90s of only 8/16 μg/ml (range, ≤1 to 32 μg/ml). FOS in combination with ceftriaxone (CRO) or azithromycin (AZT) was then evaluated using the checkerboard method for eight strains, including N. gonorrhoeae F89 (CRO-resistant) and AZT-HLR (high-level AZT-resistant). All combinations that included FOS gave indifferent effects (fractional inhibitory concentration [FIC] index values, 1.2 to 2.3 for FOS plus CRO, 1.8 to 3.2 for FOS plus AZT). Time-kill experiments for FOS, CRO, AZT, and their combinations (at 0.5×, 1×, 2×, and 4× the MIC) were performed against N. gonorrhoeae strain ATCC 49226, one N. gonorrhoeae multiantigen sequence typing (NG-MAST) sequence type 1407 (ST1407) strain, F89, and AZT-HLR. For all strains, at 24 h, the results indicated that (i) FOS was bactericidal at 2× the MIC, but after >24 h, there was regrowth of bacteria; (ii) CRO was bactericidal at 0.5× the MIC; (iii) AZT was bactericidal at 4× the MIC; (iv) CRO plus AZT was less bactericidal than was CRO alone; (v) FOS plus AZT was bactericidal at 2× the MIC; and (vi) CRO plus AZT and FOS plus CRO were both bactericidal at 0.5× the MIC, but FOS plus CRO had more rapid effects. FOS is appealing for use in the management of N. gonorrhoeae infections because of its single and oral formulation. However, our results suggest it be used in combination with CRO. After the appropriate clinical trials are conducted, this strategy could be implemented for the treatment of infections due to isolates possessing resistance to CRO and/or AZT.

    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

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

  14. 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

    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.

    Jellyfish assaulting in a great number during summer into water intakes at power plants is disposed of by land filling in plant premises. Discussions on treatment methods and tests using test machines have been carried out over four years to save disposition area and prevent odors. While it is well known that jellyfish melts in fresh water, the basic tests identified that heating and alkali treatment is effective, the fish shrinks and reduces rapidly when boiled to 80{degree}C or higher, it can be cut and crushed easily, and its solute has a high COD. A test machine having a treatment capacity of 5 tons an hour was used. The machine consists of a cutter unit, a supply pump, a draining box, a heating tank, a circulation pump and a mesh conveyer, and is capable of batch and continuous treatments. A full-size based test machine improved of transferring and solid treating functions was tested to a satisfactory result of achieving the initial intention. Installation of a full-size machine is under way. 12 figs., 8 tabs.

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

    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.

    Steroid estrogens are thought to be the major cause of feminization (intersex) in wild fish. Widely used wastewater treatment technologies are not effective at removing these contaminants to concentrations thought to be required to protect aquatic wildlife. A number of advanced treatment processes have been proposed to reduce the concentrations of estrogens entering the environment. Before investment is made in such processes, it is imperative that we compare their efficacy in terms of removal of steroid estrogens and their feminizing effects with other treatment options. This study assessed both steroid removal and intersex induction in adult and early life stage fish (roach, Rutilus rutilus). Roach were exposed directly to either secondary (activated sludge process (ASP)), tertiary (sand filtrated (SF)), or advanced (chlorine dioxide (ClO(2)), granular activated charcoal (GAC)) treated effluents for six months. Surprisingly, both the advanced GAC and tertiary SF treatments (but not the ClO(2) treatment) significantly removed the intersex induction associated with the ASP effluent; this was not predicted by the steroid estrogen measurements, which were higher in the tertiary SF than either the GAC or the ClO(2). Therefore our study highlights the importance of using both biological and chemical analysis when assessing new treatment technologies.

    Introduction The long-term success of non-surgical weight loss treatment in adults with obesity is limited by substantial relapse, and only a few evidence-based weight loss maintenance treatments exist. This clinical trial investigates the feasibility and efficacy of a social facilitation maintenance programme for weight loss maintenance, tailored to meet the needs of obese adults who have undergone a lifestyle weight loss intervention. Methods and analysis In a single-centre, open feasibility trial, 72 adults currently or previously obese or overweight who have undergone a lifestyle weight loss intervention are centrally randomised to 4 months of social facilitation maintenance treatment or treatment as a usual control condition. In 16 outpatient group sessions, the social facilitation maintenance treatment, based on a socioecological model and on evidence supporting social facilitation as a key process in maintaining weight loss, focuses on promoting interpersonal relationships to build up a healthy lifestyle for long-term weight loss maintenance. Primary outcome is the amount of weight regain at 6-month follow-up, compared with pre-treatment weight, derived from measured body weight. Secondary outcomes address feasibility, including recruitment, attrition, assessment non-completion, compliance and patients' programme evaluation; and in comparison with pre-weight loss maintenance, social and interpersonal functioning, eating behaviour and physical activity, psychological and physical symptoms, body composition and risk of comorbidity, and quality of life at post-treatment and follow-up assessments. Ethics and dissemination The study was approved by the Ethical Committee at the University of Leipzig (165-13-15072013). The study results will be disseminated through peer-reviewed publications. Trial registration number DRKS00005182. PMID:27580827

    HIV/AIDS patients are more prone for opportunistic TB infections and they are administered the combined regimen of anti-retroviral drug zidovudine (AZT) and isoniazid (INH) for therapy. However, AZT+INH treatment has been documented to induce injury and remedial measures to prevent this adversity are not clearly defined. Silibinin (SBN) is a natural hepatoprotective principle isolated from medicinal plant Silybum marianum and is currently used for therapy of various liver diseases. This study investigate the hepatotoxic potentials of AZT alone, INH alone and AZT+INH treatments and the mitigating potentials of SBN against these drugs induced toxic insults of liver in rats. Separate groups of rats (n=6 in each group) were administered AZT alone (50mg/kg b.w.), INH alone (25mg/kg, b.w.), AZT+INH (50mg/kg, b.w. and 25mg/kg, b.w.), SBN alone (100mg/kg, b.w.) and SBN+AZT+INH daily for sub-chronic period of 45days orally. The control rats received saline/propylene glycol. INH alone and AZT+INH-induced parenchymal cell injury and cholestasis of liver was evidenced by highly significant increase in the activities of marker enzymes (aspartate and alanine transaminase, alkaline phosphatase, argino succinic acid lyase), bilirubin, protein, oxidative stress parameters (lipid peroxidation, superoxide dismutase, catalase, reduced glutathione, vitamins C and E) and membrane bound ATPases were evaluated in serum/liver tissue homogenates. Histopathological studies show ballooning degradation, inflammatory lesions, lipid deposition and hydropic changes in the liver tissue. All the above biochemical and pathological changes induced by AZT+INH treatments were mitigated in rats receiving SBN simultaneously with these hepatotoxins, indicating its hepatoprotective and antioxidant potentials against AZT+INH-induced hepatotoxicity. The moderate hepatoprotective and oxidant potentials of SBN could be due to its low bioavailability and this deficiency could be prevented by supplementation of

    The study comprises an analysis of the effect of treatment with a modified activator combined with a high-pull headgear during a standardized observation period of the initial 6 months of treatment. All patients (24 girls and 32 boys, aged 8.5 to 15 years) had severe skeletal Class II malocclusion. In the first part of the study, the effect of treatment with the appliance both day and night is compared with the effect when it was worn only at night. Only a small and nonsignificant difference was found, but the patients tended to cooperate better if they were instructed to wear the appliance continuously. In the second part of the study, the effect of treatment is related to the somatic maturation of the patients. Longitudinal records of standing height were used to assess whether treatment had been performed before maximal pubertal growth (prepeak period), during maximal pubertal growth (peak period), or after maximal pubertal growth (postpeak period). The skeletal effect was significantly greater in boys treated during the peak period than in those treated during the prepeak period and a similar tendency, although not significant, was found among girls. The number of patients treated during the postpeak period was too small for statistical analysis.

  11. A study of light ion accelerators for cancer treatment

    International Nuclear Information System (INIS)

    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.

    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.

    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.

    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.

    Full Text Available Weihong Li, Shimei Wang, Yanzhen Zhang The Second Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, Zhejiang, People’s Republic of China Background: Few research projects have looked at patient satisfaction with treatment outcome and factors contributing to satisfaction. The aim of this study was to examine treatment motivation and expectation associated with treatment-outcome satisfaction in a group of adolescent nonextraction orthodontic patients. We hypothesized that there would be significant correlations among treatment-outcome satisfaction, motivation, and expectations.Subjects and methods: A sample of 120 patients who received orthodontic treatment at the Second Affiliated Hospital of Zhejiang University School of Medicine completed two questionnaires. Before treatment, questionnaire 1 was given to patients to assess treatment motivation and expectations. When treatment had been completed, questionnaire 2, concerning treatment satisfaction, was assessed. Spearman’s rank correlation and regression analyses were used to assess the relationships among treatment satisfaction, expectations, and motivation.Results: A total of 110 patients completed the two questionnaires. There was a tendency toward significant correlations between treatment motivation and overall satisfaction with treatment (β-coefficient –0.264, 95% confidence interval –0.456 to 2.314; P<0.001. However, correlations among treatment motivation and satisfaction with changes made and satisfaction with one’s appearance posttreatment were more fragmented. No relationship between treatment expectation and satisfaction was found (β-coefficient –0.126; 95% confidence interval –0.024 to 0.524; P>0.05.Conclusion: Motivation was correlated with satisfaction with treatment outcome. Patients’ expectations had no correlation with treatment satisfaction. Keywords: motivation, orthodontic treatment, expectation, treatment-outcome satisfaction

  10. Amnesia and vegetative abnormalities after irradiation treatment. A case study

    International Nuclear Information System (INIS)

    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.)

    2004-01-01

    Full Text Available In this review, the influence of lithium treatment in mouse, rat, and rabbit skin, liver, bone, and aorta, as well as arachnoid and dura mater collagen fibrils, is examined using electron microscopy and image processing. Structural changes (fibril architecture and diameter are detected at the ultrastructural level in specimens from all lithium-treated tissues. The overall collagen fibril architecture is disturbed as compared with specimens from normal species. The mean diameter values of treated collagen fibrils are significantly smaller than those from controls in all tissues examined. The banding patterns of fibrils are normal in all cases. Measurements by a computerized method of measuring axial periodicity of fibrils indicate no effect of lithium on this parameter. Computer analysis shows no differences in charged amino acid composition between lithium-treated and -untreated samples. Under the present experimental conditions, lithium can induce permanent structural collagen alterations.

    A hypothesis that the thoracic idiopathic scoliosis is buckling phenomenon of the fourth mode induced by the growth of thoracic vertebral bodies was presented in the previous work by the authors using numerical simulations with finite element model of the spine. If the hypothesis is acceptable, sensitivity function with respect to the critical growth of thoracic vertebrae on the maximization problem of buckling load with the fourth buckling mode gives us useful information to improve and develop treatments for the idiopathic scoliosis. The numerical results analyzed by the finite element method demonstrated that the sensitivity function is high at the articular capsules of the intervertebral joints, the intervertebral disks, the costotransverse joints and the constovertebral joints around the apex of the curvature in the case of the thoracic idiopathic scoliosis.

    1999-06-01

    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.

    A self-made anaerobic bio-filter bed which was inoculated with special sludge showed high efficiency in removing hexavalent chromium. When pump flow was 47 ml/min and COD(Cr) of wastewater was about 140 mg/L, it took 4 h to decrease the Cr6+ concentrations from about 60 mg/L to under 0.5 mg/L, compared with 14 h without carbon source addition. Cr6+ concentrations ranged from 64.66 mg/L to 75.53 mg/L, the system efficiency was excellent. When Cr6+ concentration reached 95.47 mg/L, the treatment time was prolonged to 7.5 h. Compared with the contrast system, the system with trace metals showed clear superiority in that the Cr6+ removal rate increased by 21.26%. Some analyses also showed that hexavalent chromium could probably be bio-reduced to trivalent chromium, and that as a result, the chrome hydroxide sediment was formed on the surface of microorganisms.

    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

  3. 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.

    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 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.

    Full Text Available Background: Lennox-Gastaut syndrome (LGS is a severe childhood epileptic syndrome with high pharmacoresistance. The treatment outcomes are still unsatisfied. Our previous study of cathodal transcranial direct current stimulation (tDCS in children with focal epilepsy showed significant reduction in epileptiform discharges. We hypothesized that cathodal tDCS when applied over the primary motor cortex (M1 combined with pharmacologic treatment will be more effective for reducing seizure frequency in patients with LGS than pharmacologic treatment alone. Material and Method: Study participants were randomized to receive either (1 pharmacologic treatment with 5-consecutive days of 2 mA cathodal tDCS over M1 for 20 min or (2 pharmacologic treatment plus sham tDCS. Measures of seizure frequency and epileptic discharges were performed before treatment and again immediately post-treatment and 1-, 2-, 3-, and 4-week follow-up. Result: Twenty two patients with LGS were enrolled. Participants assigned to the active tDCS condition reported significantly more pre- to post-treatment reductions in seizure frequency and epileptic discharges that were sustained for 3 weeks after treatment.Conclusion: Five consecutive days of cathodal tDCS over M1 combined with pharmacologic treatment appears to reduce seizure frequency and epileptic discharges. Further studies of the potential mechanisms of tDCS in the LGS are warranted.Trial Registration: ClinicalTrials.gov, NCT02731300 (https://register.clinicaltrials.gov.

    The aim of this study is to evaluate the treatment outcomes and identify factors associated with adverse tuberculosis treatment outcomes for bacteriologically confirmed pulmonary tuberculosis. Treatment outcomes of pulmonary tuberculosis were evaluated retrospectively among 11,186 smear- and/or culture-positive patients treated between 2006 and 2009 in Istanbul, Turkey. Adverse treatment outcomes were identified in 1,010 (9.0%) patients including death (1.8%), treatment default (6.1%), and treatment failure (1.1%). Factors associated with adverse treatment outcomes included being born abroad (odds ratios [OR], 5.38; 95% confidence intervals [CI], 3.67-7.91), history of tuberculosis treatment (OR, 3.77; 95% CI, 3.26-4.36), age > 65 years (OR, 2.79; 95% CI, 2.21-3.53), and male gender (OR, 1.91; 95% CI, 1.59-2.27). Death was most strongly associated with age > 65 years (OR, 45.1; 95% CI, 27.0-75.6), followed by treatment default with history of interrupted treatment (OR, 11.6; 95% CI, 8.94-15.1), and treatment failure with prior history of treatment failure (OR, 17.1; 95% CI, 6.97-41.6). Multidrug resistance was strongly associated with adverse treatment outcomes (OR, 10.8; 95% CI, 8.02-14.6). Age > 65 years, male sex, being born abroad, and history of treatment failure were found to be risk factors for adverse treatment outcomes. Hence, patients with any of these characteristics should be carefully monitored and treated aggressively.

  4. External root resorption after orthodontic treatment: a study of contributing factors

    International Nuclear Information System (INIS)

    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.

    Full Text Available This study was perfomed on twenty five teeth which showed radiographic lesions( 6mm over 25 mm. the teeth were arranged in seven different groups and root canal therapy ( by warm Gutta-percha technique as surgical intervention were performed at various time intervals. In this investigation, histologic studies of the periapical tissues begin shortly after elimination of the root canal system with or without root  canal obturation. This healing demonstrated with a replacement of granulation tissue by connective tissue, inflammatory cells diminish in number and densityb fibroblastic activity and their differentiation of osteoblastc osteoblastic activity forming osteoid and trabecular bone. The newly formed trabeculae extend from the periphery of the lesion to the center and root surfacesd nonorganized periodontal ligament fibers return to their original orientation soon after the newly formed trabeculae reach the apical root surface and form lamina duraInflammatory responses may continue simultaneously with periapical tissue regeneration and bone formation. Chronic inflammatory cells seem to be present occasionally in marrow spaces of the newly formed bone. Cellular activity and bone formation are demonstrated in the presence of the lining epithelium. This is seen between newly formed bone and apical root tip and might be suggestive of healing of the periapical cyst.

    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

    International Nuclear Information System (INIS)

    To determine whether there is a relationship between abnormal temporomandibular joint radiographic findings and age or gender in a sample of preorthodontic patients. Individualized corrected sagittal tomographs of 188 temporomandibular joints in 94 preorthodontic patients, aged 11 to 29 years, were taken and viewed by an observer blinded to clinical records. The study population was divided into 2 aged groups (11-15 years and 16-29 years) for comparative purpose. Temporomandibular joint radiographic findings were classified as normal or abnormal. There was no difference in ratio of abnormal to normal findings between the both aged groups. The frequency of osseous abnormalities was similar with that of abnormalities of condylar position. Abnormalities in CP and JS were most frequent in all aged groups. There is no significant difference between ages or genders for temporomandibular joint radiographic abnormalities

Methods: The subjects were patients diagnosed with lumbar spine sprain and hospitalized at Suncheon oriental medical hospital, which was randomly divided into sweet BV parallel treatment group and acupuncture-only group, and other treatment conditions were maintained the same. Then,VAS (Visual Analogue Scale was used to compare the difference in the treatment period between the two groups from VAS 10 to VAS 0, from VAS 10 to VAS 5, and from VAS 5 to VAS 0. Result & Conclusion: Sweet BV parallel treatment group and acupuncture-only treatment group were compared regarding the respective treatment period, and as the result, the treatment period from VAS 10 to VAS 5 was significantly reduced in sweet BV parallel treatment group compared to the acupuncture-only treatment group, but the treatment period from VAS 5 to VAS 0 did not show a significant difference. Therefore, it can be said that sweet BV parallel treatment is effective in shortening the treatment period and controlling early pain compared to acupuncture-only treatment.

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

    Directory of Open Access Journals (Sweden)

    Dogaru Gabriela

    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

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the initial and postoperative radiographic features of the endodontic treated teeth. The author examined the radiographs which comprise 114 teeth with 155 canals of 64 persons. The following factors were considered; Age, sex, tooth location, number of root canal, postoperative periods, initial diagnosis, and radiographic findings, postoperative radiographic findings. The apical levels of the root fillings were 76.8% to apex, 19.0% underfilling, 3.9% overfilling. The following results were obtained. 1. Of the 93 teeth which revealed initial periapical rarefaction, 66 teeth(71.0%) had showed complete bone healing, 19 teeth (20.4%) decreased rarefaction, 6 teeth (6.5%) no change, 2 teeth (2.2%) increased rarefaction after 20.0 months mean healing time. 2. 21 teeth which had on initial periapical rarefaction showed no occurrence of new periapical rarefaction. 3. Of the 66 teeth completely healed, 53 teeth (80.3%) had showed reappearance of laminadura, 64 teeth (97.0%) reappearance of periodontal ligament space after 23.4 months mean healing time.

    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.

    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

    Cigarette smoking is widely prevalent among individuals in treatment for drug or alcohol dependence; however, the treatment of nicotine addiction in this population has numerous obstacles at both programmatic and patient levels. Despite these difficulties, recent studies have demonstrated moderate success in implementing smoking cessation treatment in drug rehabilitation programs. The National Drug Abuse Treatment Clinical Trials Network sponsored a smoking cessation study in 13 community-based outpatient substance abuse rehabilitation programs across the country. The study evaluated the effectiveness of smoking cessation treatment provided as an adjunct to substance abuse treatment-as-usual. This report summarizes the practical and clinical experiences encountered at each of the study sites with regard to implementing the smoking cessation treatment intervention. Smoking behavior of the treatment clientele was assessed by anonymous survey at each site. In addition, sites were systematically characterized by using program review and assessment tools completed by the respective staff and program directors at the site. Survey and recruitment data indicated that cigarette smoking is more prevalent and that smoking cessation treatment is more feasible, in methadone maintenance treatment programs. Other factors associated with smoking behavior and with the recruitment of drug- and alcohol-dependent individuals into the smoking cessation treatment study are described.

    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

    Thermal plasma was applied for the treatment of coke wastewater sludge derived from the steel industry in order to investigate the feasibility of the safe treatment and energy recovery of the sludge. A 30 kW plasma torch system was applied to study the vitrification and gas production of coke wastewater sludge. Toxicity leaching results indicated that the sludge treated via the thermal plasma process converted into a vitrified slag which resisted the leaching of heavy metals. CO2 was utilized as working gas to study the production and heat energy of the syngas. The heating value of the gas products by thermal plasma achieved 8.43 kJ/L, indicating the further utilization of the gas products. Considering the utilization of the syngas and recovery heat from the gas products, the estimated treatment cost of coke wastewater sludge via plasma torch was about 0.98 CNY/kg sludge in the experiment. By preliminary economic analysis, the dehydration cost takes an important part of the total sludge treatment cost. The treatment cost of the coke wastewater sludge with 50 wt.% moisture was calculated to be about 1.45 CNY/kg sludge dry basis. The treatment cost of the coke wastewater sludge could be effectively controlled by decreasing the water content of the sludge. These findings suggest that an economic dewatering pretreatment method could be combined to cut the total treatment cost in an actual treatment process.

    The aim of this study was to examine the extent of psychiatric patients' compliance and non-compliance with treatment and examine the factors that affect compliance. Patients were recruited who were between 16 and 60 years of age and who were hospitalized with a psychiatric disorder and treated in the outpatient clinics of the psychiatry department. A total of 689 patients were approached and 564 patients agreed to participate in the study, a response rate of 81.8%. Participants were asked to complete a questionnaire that asked about socio-demographic characteristics (e.g., age, gender, nationality, level of education, occupation, marital status, and life style habits); medication(s) prescribed and the participant's response; the degree of social supervision (rated subjectively by the patient as "poor," "good," or "very good"); data also were obtained from clinical records. Data analyses explored significant associations between compliance and non-compliance and a group of relevant variables. Of the 564 patients studied, 328 (58.2%) were compliant with treatment and 236 (41.8%) were non-compliant. There was no significant difference between compliance and non-compliance in terms of gender (p = 0.471). Patients between 21-30 years of age were significantly more compliant with drug treatment than not. Non-compliance was more common among patients diagnosed with schizophrenia (28.4%), followed by depression (14.4%), and bipolar affective disorder (12.7%) (p = 0.001). Only 25% of compliant patients and 26.3% of non-compliant patients used non-psychotropic medication. Social supervision (40%) was very poor in non-compliant patients whereas 49.4% of compliant patients had very good family support. Notable reasons for non-compliance were irregular attendance to clinic (55.5%), ignorance about side effects of medication (61%), free medicine (45.8%), and a lack of education about medication (58.1%). This study revealed that non-compliance rates among psychiatry patients

    2012-01-01

    Full Text Available Metastatic renal cell carcinoma (RCC seems to be resistant to conventional chemo- and radiotherapy and the general treatment regimen of cytokine therapy produces only modest responses while inducing severe side effects. Nowadays standard of care is the treatment with VEGF-inhibiting agents or mTOR inhibition; nevertheless, immunotherapy can induce complete remissions and long-term survival in selected patients. Among different adoptive lymphocyte therapies, cytokine-induced killer (CIK cells have a particularly advantageous profile as these cells are easily available, have a high proliferative rate, and exhibit a high antitumor activity. Here, we reviewed clinical studies applying CIK cells, either alone or with standard therapies, for the treatment of RCC. The adverse events in all studies were mild, transient, and easily controllable. In vitro studies revealed an increased antitumor activity of peripheral lymphocytes of participants after CIK cell treatment and CIK cell therapy was able to induce complete clinical responses in RCC patients. The combination of CIK cell therapy and standard therapy was superior to standard therapy alone. These studies suggest that CIK cell immunotherapy is a safe and competent treatment strategy for RCC patients and further studies should investigate different treatment combinations and schedules for optimal application of CIK cells.

    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 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.

    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.

    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.

    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 Internet-based self-help treatment with minimal therapist contact has been shown to have an effect in treating various conditions. The objective of this study was to explore participants' views of Internet administrated guided self-help treatment for depression. Methods In-depth interviews were conducted with 12 strategically selected participants and qualitative methods with components of both thematic analysis and grounded theory were used in the analyses. Results Three distinct change processes relating to how participants worked with the treatment material emerged which were categorized as (a Readers, (b Strivers, and (c Doers. These processes dealt with attitudes towards treatment, views on motivational aspects of the treatment, and perceptions of consequences of the treatment. Conclusions We conclude that the findings correspond with existing theoretical models of face-to-face psychotherapy within qualitative process research. Persons who take responsibility for the treatment and also attribute success to themselves appear to benefit more. Motivation is a crucial aspect of guided self-help in the treatment of depression.

    Full Text Available Abstract Background We translated, modified, and extended a cognitive behavioral treatment (CBT protocol by Blanchard and Hickling (2003 for the purpose of treating survivors of MVA with full or subsyndromal posttraumatic stress disorder (PTSD whose native language is German. The treatment manual included some additional elements, e. g. cognitive procedures, imaginal reliving, and facilitating of posttraumatic growth. The current study was conducted in order to test the efficacy of the modified manual by administering randomized controlled trial in which a CBT was compared to a wait-list control condition. Methods Forty-two motor vehicle accident survivors with chronic or severe subsyndromal posttraumatic stress disorder (PTSD completed the treatment trial with two or three detailed assessments (pre, post, and 3-month follow-up. Results CAPS-scores showed significantly greater improvement in the CBT condition as compared to the wait list condition (group × time interaction effect size d = 1.61. Intent-to-treat analysis supported the outcome (d = 1.34. Categorical diagnostic data indicated clinical recovery of 67% (post-treatment and 76% (3 months FU in the treatment group. Additionally, patients of the CBT condition showed significantly greater reductions in co-morbid major depression than the control condition. At follow-up the improvements were stable in the active treatment condition. Conclusion The degree of improvement in our treatment group was comparable to that in previously reported treatment trials of PTSD with cognitive behavioral therapy.

    This work provides a case study on how activated sludge modelling and computational fluid dynamics (CFD) can help to optimize the energy consumption of a treatment plant that is already equipped with an advanced control based on online nutrient measurements. Currently, aeration basins on wastewater treatment plant Antwerp-South are operated sequentially while flow direction and point of inflow and outflow vary as a function of time. Activated sludge modelling shows that switching from the existing alternating flow based control to a simultaneous parallel feeding of all aeration tanks saves 1.3% energy. CFD calculations also illustrate that the water velocity is still sufficient if some impellers in the aeration basins are shutdown. The simulations of the Activated Sludge Model No. 2d indicate that the coupling of the aeration control with the impeller control, and automatically switching off some impellers when the aeration is inactive, can save 2.2 to 3.3% of energy without affecting the nutrient removal efficiency. On the other hand, all impellers are needed when the aeration is active to distribute the oxygen.

    Dydrogesterone is an oral retroprogesterone widely used to treat progesterone deficiencies, including irregular menstrual cycles (MCs). This prospective, non-interventional, single-arm, post-marketing, observational study evaluated the effects of dydrogesterone on MC regularization. Women aged 18-40 years who had been prescribed dydrogesterone to treat irregular MCs due to progesterone deficiency were enrolled across 64 centers in Russia, Ukraine, Kazakhstan and Uzbekistan. Study objectives included: patients reporting ≥1 regular MC during treatment; the number of regular MCs after the end of treatment over a 6-month follow-up (FU) period. In total, 996 women were enrolled. Of those who completed treatment, 946/955 patients (99.1%) achieved ≥1 regular MC. During FU, 680/860 patients (79.1%) maintained ≥6 regular MCs. Patient grading of menstrual pain and anxiety decreased significantly during treatment (p ≤ 0.0001 versus baseline); this persisted during FU. Dydrogesterone was associated with high or very high patient satisfaction (856/955; 89.6%); the clinical response was considered good or excellent in 819/955 patients (85.8%). In total, 16/986 patients (1.6%) reported an adverse event (AE); two had serious AEs (SAEs) (unrelated to treatment) and three discontinued treatment due to non-SAEs. Dydrogesterone therapy was effective in achieving MC regularization and reducing menstrual pain and anxiety, during both treatment and 6-month FU. PMID:26613278

    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.

    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.

  15. Prevalence and Treatment Management of Oropharyngeal Candidiasis in Cancer Patients: Results of the French Candidoscope Study

    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.

    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

    In in vitro tests, natural coniferous resin from the Norway spruce (Picea abies) is strongly antifungal. In this observational study, we tested the clinical effectiveness of a lacquer composed of spruce resin for topical treatment of onychomycosis. Thirty-seven patients with clinical diagnosis of onychomycosis were enrolled into the study. All patients used topical resin lacquer treatment daily for 9 months. A mycological culture and potassium hydroxide (KOH) stain were done from nail samples in the beginning and in the end of the study. Treatment was considered effective, if a mycological culture was negative and there was an apparent clinical cure. At study entry, 20 patients (20/37; 54%; 95% CI: 38-70) had a positive mycological culture and/or positive KOH stain for dermatophytes. At study end, the result of 13 patients was negative (13/19; 68%; 95% CI: 48-89). In one case (1/14; 7%; 95% CI: 0-21) the mycological culture was initially negative, but it turned positive during the study period. By 14 compliant patients (14/32; 44%; 95% CI: 27-61), resin lacquer treatment was considered clinically effective: complete healing took place in three cases (9%) and partial healing in 11 cases (85%). The results indicate some evidence of clinical efficacy of the natural coniferous resin used for topical treatment of onychomycosis.

The source of data was the TB registry system in Iran and 964 patients were eligible for the study. The life table was used to determine the annual survival rate. Survival curves were estimated using Kaplan-Meier and were compared using the log-rank test. In order to determine the predictors of survival, four models of Cox regression, exponential, Weibull and log-logistic fitted and finally exponential model with minimum akaike information criteria and Bayesian information criterion values were selected. Then, variables with significant levels <0.2 in univariate analysis were entered into the multivariate model. Hazard ratios with a confidence interval of 95% were used to measure the association. Results: A total of 149 patients (15.5% died during the follow-up period. The median of survival time after successful treatment was 10.5 years and survival probability for 11 years after successful treatment was 70%. Furthermore, previous TB treatment, high age, suffering from kidney failure and cancer were predictors of mortality after successful treatment. Conclusions: This study showed that positive smear pulmonary tuberculosis even after successful treatment has an adverse effect on the patients′ survival and leads to a decrease in their survival rate in the long run. Furthermore, individuals with a history of previous TB treatment had much lower survival rates.

    2012-01-01

    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

The therapeutic efficacy and the incidence of adverse reactions due to D4T and AZT among the 3 groups were observed. Results The median CD4+ counts in the 3 groups before and after the 96-week treatment in group A were 219 (15-332) ×106/L and 420(203-635) × 106/L Group B were 224(28-332) ×106/L and 366 (178-724) × 106/L in respectively; and those in Group C were 153(19 - 350) × 106/L and 411(95-728) × 106/L respectinely. The rates of plasma HIV RNA lower than 40 copies/mL were 92. 6% in Group A, 96. 3% in Group B and 100% in Group C. The rate of adverse reactions related with D4T reached 81.48% in Group A, which mainly occurred after 36 weeks treatment; the rate of AZT related adverse reactions was 48. 15% in Group B, which occurred in the first 12 weeks after beginning ART; and in Group C, D4T was changed to AZT after 24 weeks, then the rates of adverse reactions due to D4T was 0 and that due to AZT was 9. 25%, obviously lower than in Group A (P<0. 05)and Group B (P<0. 05). Conclusion The optimized HAART regimen using D4T for the first 24 weeks, and then switching to AZT showed the same satisfactory therapeutic efficacy as compared with the regimens based on D4T or AZT used for a long term,but the rate of adverse reactions in the former was obviously lower than in the latter. The optimized regimen can be recommended as an initial antiretroviral therapy based on domestically manufactured generic drugs.

    2010-06-01

    Diabetic foot ulcers (DFU) are common, difficult-to-treat, and prone to complications. A prospective, controlled study was conducted to: 1) examine the clinical efficacy of a pressurized topical oxygen therapy (TWO(2)) device in outpatients (N = 28) with severe DFU referred for care to a community wound care clinic and 2) assess ulcer reoccurrence rates after 24 months. Seventeen (17) patients received TWO(2) five times per week (60-minute treatment, pressure cycles between 5 and 50 mb) and 11 selected a silver-containing dressing changed at least twice per week (control). Patient demographics did not differ between treatment groups but wounds in the treatment group were more severe, perhaps as a result of selection bias. Ulcer duration was longer in the treatment (mean 6.1 months, SD 5.8) than in the control group (mean 3.2 months, SD 0.4) and mean baseline wound area was 4.1 cm2 (SD 4.3) in the treatment and 1.4 cm2 (SD 0.6) in the control group (P = 0.02). Fourteen (14) of 17 ulcers (82.4%) in the treatment group and five of 11 ulcers (45.5%) in the control group healed after a median of 56 and 93 days, respectively (P = 0.04). No adverse events were observed and there was no reoccurrence at the ulcer site after 24 months' follow-up in either group. Although the absence of randomization and blinding may have under- or overestimated the treatment effect of either group, the significant differences in treatment outcomes confirm the potential benefits of TWO(2) in the management of difficult-to-heal DFUs. Clinical efficacy and cost-effectiveness studies as well as studies to elucidate the mechanisms of action of TWO(2) are warranted. PMID:20567051

    Objective: The objective of this study was to compare the light transmittance of fiber posts following application of various surface treatments. Materials and Methods: Fiber post specimens (Snowpost red size #14) were tested (n = 7). The fiber posts were divided into five groups according to the application of surface treatments: Group 1: No surface treatment; Group 2: Etched with hydrofluoric acid (HF) + silane application; Group 3: Airborne-particle abraded with 110 μm Al2O3; Group 4: Irradiated with erbium: Yttrium-aluminum-garnet laser; Group 5: Airborne-particle abraded with 110 μm Al2O3 + silane application. The light transmittance of the specimens was compared using a spectrophotometer. Statistical significance was determined using one-way analysis of variance (ANOVA) (α = 0.05). Results: One-way ANOVA revealed that surface treatment had significant effects on light transmittance of posts (P < 0.001). While laser treatment had the highest percentage of light transmittance, treatment with silane following HF application had the lowest. Conclusion: Application of surface treatments might negatively affect the light transmission property of fiber posts. PMID:27095902

    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

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.

    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. It was observed that plasma treatment of

While no consistent pattern of sociodemographic or clinical features associated with nonadherence emerged, all studies that investigated cognitive variables in panic disorder, social anxiety disorder, and obsessive-compulsive disorder found that expectations and opinions about treatment were related to adherence.Conclusion: The findings of this study suggest that it is essential to consider anxiety disorder patients’ beliefs about illness and treatment strategies to increase their compliance with the therapeutic plan.Keywords: attrition, dropout, OCD, obsessive-compulsive disorder, social anxiety disorder

  7. Ahead of its time: 40 years after the advice versus treatment family study.

    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

  8. Application of Induced Mutation by Using Gamma Ray Treatment in Study Breeding for Orchid (Phalaenopsis) Varieties

    International Nuclear Information System (INIS)

    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.

  9. Integrated Thermal Treatment Systems study: US Department of Energy Internal Review Panel report

    International Nuclear Information System (INIS)

    The U.S. Department of Energy's (DOE) Office of Technology Development (OTD) commissioned two studies to uniformly evaluate nineteen thermal treatment technologies. These studies were called the Integrated Thermal Treatment System (ITTS) Phase I and Phase II. With the advice and guidance of the DOE Office of Environmental Management's (EM's) Mixed Waste Focus Group, OTD formed an ITTS Internal Review Panel, composed of scientists and engineers from throughout the DOE complex, the U.S. Environmental Protection Agency (EPA), the California EPA, and private experts. The Panel met from November 15-18, 1994, to review and comment on the ITTS studies, to make recommendations on the most promising thermal treatment systems for DOE mixed low level wastes (MLLW), and to make recommendations on research and development necessary to prove the performance of the technologies on MLLW

  10. A Study of Atmospheric Plasma Treatment on Surface Energetics of Carbon Fibers

    International Nuclear Information System (INIS)

    In this study, the atmospheric plasma treatment with He/O2 was conducted to modify the surface chemistry of carbon fibers. The effects of plasma treatment parameters on the surface energetics of carbon fibers were experimentally investigated with respect to gas flow ratio, power intensity, and treatment time. Surface characteristics of the carbon fibers were determined by X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), Fourier transform infrared (FT-IR), Zeta-potential, and contact angle measurements. The results indicated that oxygen plasma treatment led to a large amount of reactive functional groups onto the fiber surface, and these groups can form together as physical intermolecular bonding to improve the surface wettability with a hydrophilic polymer matrix

    This study investigated the effects of a manualized therapy for video game addiction in 12 males, ages 14-18 yr. 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.

    Full Text Available The objective was to investigate the effect of nitrous/oxygen in chronic pain. Seventy-seven chronic pain patients referred to dental treatment with conscious sedation with nitrous oxide/oxygen had their records included in this research. Data were collected regarding the location and intensity of pain by the visual analogue scale before and after the treatment. Statistical analysis was performed comparing pre- and post-treatment findings. It was observed a remarkable decrease in the prevalence of pain in this sample (only 18 patients still had chronic pain, p < 0.001 and in its intensity (p < 0.001. Patients that needed fewer sessions received higher proportions of nitrous oxide/oxygen. Nitrous oxide may be a tool to be used in the treatment of chronic pain, and future prospective studies are necessary to understand the underlying mechanisms and the effect of nitrous oxide/oxygen in patients according to the pain diagnosis and other characteristics.

    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

    International Nuclear Information System (INIS)

    Sterilization of medical aid articles (e.g. catheters, one-way syringes) with ionizing radiation is a successful practice in many countries. During recent years, the results from numerous experiments of radiosterillization of pharmaceuticals and adjuvants have likewise been published. Experience has shown that radiation treatment, in many cases, is leading to transformations of the irradiated substances. In the present part IX of the bibliographic study on the influence of radiation treatment on pharmaceuticals and adjuvants the results of experiments on ca. 80 substances from 36 different sources have been evaluated. In all parts of the study results of about 560 experiments on 360 substances from 176 different sources are present. (orig.)

    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

    Full Text Available Abstract Background In order to compare the effectiveness of different antipsychotic drugs in the treatment of schizophrenia it is very important to evaluate subjective response and compliance in patient cohorts treated according to routine clinical practice. Method Outpatients with schizophrenia entered this prospective, naturalistic study when they received a new prescription for an antipsychotic drug. Treatment assignment was based on purely clinical criteria, as the study did not include any experimental intervention. Patients treated with olanzapine, risperidone or haloperidol were included in the analysis. Subjective response was measured using the 10-item version of the Drug Attitude Inventory (DAI-10, and treatment compliance was measured using a physician-rated 4 point categorical scale. Results A total of 2128 patients initiated treatment (as monotherapy with olanzapine, 417 with risperidone, and 112 with haloperidol. Olanzapine-treated patients had significantly higher DAI-10 scores and significantly better treatment compliance compared to both risperidone- and haloperidol-treated patients. Risperidone-treated patients had a significantly higher DAI-10 score compared to haloperidol-treated patients. Conclusion Subjective response and compliance were superior in olanzapine-treated patients, compared to patients treated with risperidone and haloperidol, in routine clinical practice. Differences in subjective response were explained largely, but not completely, by differences in incidence of EPS.

    2006-01-01

    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.

    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

  8. Driving simulators for robust comparisons: a case study evaluating road safety engineering treatments.

    Road authorities considering the implementation of speed management interventions should have access to the results of scientifically robust evaluations on which to base their decisions. However, studies that evaluate a diverse range of interventions with comparable metrics are rare, with most focussing on one type, for example, types of signage, perceptual countermeasures or physical traffic calming. This paper describes a driving simulator study designed to overcome these constraints. Twenty diverse speed-reducing treatments were developed and tested in urban and rural road environments. Forty participants encountered all the treatments allowing a comparison to be made with their driving behaviour when the treatment was not present. A number of speed parameters were developed to encapsulate the range of effects of the treatments. The results suggest that whilst straight sections of road are difficult to treat, speed reductions can be obtained by increasing risk perception. In contrast, alerting treatments had more effect at junctions, particularly in an urban environment; drivers approaching curves demonstrated improved speed adaptation if the curve radius was highlighted (either implicitly or explicitly). The study highlights how driving simulators can be used to overcome methodological constraints encountered in real-world evaluations of this type.

    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.

    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 Context: India has the highest tuberculosis (TB burden in the world in terms of the absolute number of cases that occur each year. The directly observed treatment, short-course (DOTS strategy is the most systematic and cost-effective approach to controlling this disease. Furthermore, understanding the specific reasons for treatment outcomes is important for the improvement of treatment systems. Aims: This study aimed to determine certain sociodemographic factors that contribute to TB treatment outcome. Settings and Design: A prospective study was conducted among 302 TB patients at four designated microscopy centers (DMCs of Aligarh District, Uttar Pradesh from April 2012 to June 2013. Materials and Methods: Study subjects were followed up from the initiation to the end of treatment. Baseline data were collected using a pretested questionnaire. The subjects were interviewed at least 3 times each during their treatment. Outcomes were considered as per the Revised National Tuberculosis Control Programme (RNTCP standard definition. "Cured" and "treatment completed" were considered good outcomes, while "default," "failure," and "death" were considered poor outcomes. Statistical Analysis Used: Data were analyzed in SPSS 17 using the chi-square test and univariate logistic regression to determine the association. The odds ratio (OR and 95% confidence interval (CI were calculated in logistic regression. Results: The majority of the subjects were male (72.2% and in the age group of 15-30 years. Among the subjects, 53% resided in urban areas; 63.6% were literate; and 45% had a high standard of living index (SLI. Age group, literacy status, and SLI were found to be significantly associated with outcome (P < 0.05. On logistic regression, the 31-45-years age group, literacy, and high SLI were found to be significantly associated with good outcome.

    Full Text Available Background: Tennis elbow is a common orthopedic disease affecting elbow in middle aged people. Ninety percent of patients are cured using conservative treatments. In the past, emphasis was placed on the use of long arm splints for its treatment; however, recent studies put doubt on the use of this method of treatment for the complications arising from the application of splints. The results of using long arm splints for the treatment of Methods: This was a case series non randomized clinical trial involving 25 patients treated with long arm castsplints, and 25 patients treated without the use of splint. Local corticosteroid injections and oral NSAIDs were administered for all patients. The two groups were compared in the third week, third month and sixth month of their treatment for the presence of local tenderness and pain in passive flexion test of wrist and fingers against resistance. Using SPSS 9.0, data were analyzed via repeated measurements test of ANOVA Results: Patients in case and control groups had mean ages 43.6 ± 7.2 and 43.6 ± 6 years, respectively. Prior to any treatments, all patients in this study suffered from pain and tenderness in the origin of forearm extensor muscles. Their pain exacerbated upon passive flexion of wrist and fingers against resistance. No significant difference was seen in third week, third month and sixth month (P value =0.32, and no significant difference was seen in the results of our tests regarding the presence of local tenderness and pain in passive flexion of wrist and fingers against resistance between the two groups Conclusions: After a follow-up period of six months, this study demonstrated no statistically significant difference between the two groups treated with and without long arm splints.

    Economic feasibility assessments represent a key issue for selecting which wastewater treatment processes should be implemented. The few applications that exist focus on the positive economic value of externalities, overlooking the existence of negative externalities. However, wastewater treatment plants (WWTPs) consume a significant amount of energy, contributing to climate change. In this context, as a pioneering approach, greenhouse gas emissions (GHG) have been incorporated as a negative externality of wastewater treatment. Within this framework, this study aims to compare the economic feasibility of five technologies, both intensive and extensive, for small communities. The results show that both the investment and operation costs are higher for intensive than for extensive technologies. Moreover, significant differences in the value of negative externalities were observed. This study demonstrates that from an economic perspective, constructed wetland is the most suitable option for treating wastewater in small agglomerations.

    Full Text Available Dye wastewater is considered pollutant because it may contain polyaromatic substances known as carcinogenic, mutagenic and teratogenic to a variety of living species. Within the many treatment methods, the electrocoagulation/electroflotation method has been widely studied and it is known to be very effective. However, there is currently no industrial use of it in Colombia, and it is not a priority in academic investigation either. Because of this, this work is an exploratory study of the treatment of printing dye wastewater through the electrocoagulation/electroflotation method. A 22 with a central point experimental design was applied. Removal percentage of OCD (Oxygen Chemical Demand of the wastewater was obtain between 10,43% and 50,93%. Nevertheless, results show that decontamination through this treatment method may be reversible, and the expected incidence of factors is not observed.

    During orthodontic therapy, patients frequently complain about pain and discomfort, especially during insertion of fixed appliances. Skeletal anchorage using an interdental microimplant is a new concept in orthodontic treatment. The purpose of this study was to investigate differences and changes in the level of pain among patients in relation to orthodontic microimplant treatments. Forty microimplants were applied to the maxilla as skeletal anchors in the orthodontic treatment. The visual analog scale (VAS) was used to evaluate the patients' perception of pain during this new modality treatment. The premolar extraction VAS core was used as a baseline for the complete orthodontic procedure. The mean VAS score was 35.8 mm at 24 h after premolar extraction. The mean VAS score for insertion and removal of the microimplant 24 h after the operation was 12.3 and 7.8 mm, respectively. Three months after removal of the skeletal anchors, the VAS score had decreased to 3.2 mm and was the same as with the traditional orthodontic treatment. By using the repeated-measure general linear model (GLM), we found that the score 1 day after microimplant placement was significantly less than that 1 day after first premolar extraction or that 1 day after fixed appliance insertion. This result indicates that interdental microimplant did not generate any greater pain than other orthodontic procedures. Therefore, patients were willing to adopt the new orthodontic treatment.

  2. 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

    This treatment-development study is a Stage I evaluation of an intervention that combines mindfulness meditation with cognitive-behavior therapy for insomnia (CBT-I). Thirty adults who met research diagnostic criteria for Psychophysiological Insomnia (Edinger et al., 2004) participated in a 6-week, multi-component group intervention using mindfulness meditation, sleep restriction, stimulus control, sleep education, and sleep hygiene. Sleep diaries and self-reported pre-sleep arousal were assessed weekly while secondary measures of insomnia severity, arousal, mindfulness skills, and daytime functioning were assessed at pre-treatment and post-treatment. Data collected on recruitment, retention, compliance, and satisfaction indicate that the treatment protocol is feasible to deliver and is acceptable for individuals seeking treatment for insomnia. The overall patterns of change with treatment demonstrated statistically and clinically significant improvements in several nighttime symptoms of insomnia as well as statistically significant reductions in pre-sleep arousal, sleep effort, and dysfunctional sleep-related cognitions. In addition, a significant correlation was found between the number of meditation sessions and changes on a trait measure of arousal. Together, the findings indicate that mindfulness meditation can be combined with CBT-I and this integrated intervention is associated with reductions in both sleep and sleep-related arousal. Further testing of this intervention using randomized controlled trials is warranted to evaluate the efficacy of the intervention for this population and the specific effects of each component on sleep and both psychological and physiological arousal.

    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

    Full Text Available Abstract Background Tuberculosis treatment failure and death rates are low in the Western Pacific Region, including Vietnam. However, failure or death may also occur among patients who did not complete treatment, i.e. reported as default or transfer-out. We aimed to assess the proportion failures and deaths among new smear-positive pulmonary tuberculosis patients with reported default or transfer-out. Treatment outcomes rates were 1.4% default, 3.0% transfer-out, 0.4% failure and 2.6% death in northern Vietnam in 2003. Methods Tuberculosis patients in 32 randomly selected district tuberculosis units in northern Vietnam were followed up 1 to 3 years after treatment initiation for survival, recent treatment history and bacteriologically confirmed tuberculosis. Results Included were 85 transferred patients and 42 who defaulted. No information was available of 41 (32%, 28 (22% had died. Fifty-eight were available for follow-up (46%; all had sputum smear results. Tuberculosis was recorded in 11 (13%, including 6 (7% with positive sputum smears, 3 (3% with negative smears but positive culture and 2 (2% who had started re-treatment for bacteriologically confirmed tuberculosis. Fifteen (17%, 95%CI 10–27% had died within 8 months after treatment initiation. Of 86 patients with known study outcomes, 39 (45%, 95%CI 35–56% had died or had bacteriologically confirmed tuberculosis. This was recorded for 29/53 (55%, 95%CI 40–68% transferred patients and 10/33 (30%, 95%CI 16–49% patients who defaulted. Conclusion The total failure and death rates are 0.6% and 0.8% higher than based on routine reporting in northern Vietnam. Although this was a large proportion of treatment failures and deaths, failure and death rates were low. Defaulting and transfer carry a high risk of failure and in particular death.

  7. Moving towards best practice when using inverse probability of treatment weighting (IPTW) using the propensity score to estimate causal treatment effects in observational studies.

    The propensity score is defined as a subject's probability of treatment selection, conditional on observed baseline covariates. Weighting subjects by the inverse probability of treatment received creates a synthetic sample in which treatment assignment is independent of measured baseline covariates. Inverse probability of treatment weighting (IPTW) using the propensity score allows one to obtain unbiased estimates of average treatment effects. However, these estimates are only valid if there are no residual systematic differences in observed baseline characteristics between treated and control subjects in the sample weighted by the estimated inverse probability of treatment. We report on a systematic literature review, in which we found that the use of IPTW has increased rapidly in recent years, but that in the most recent year, a majority of studies did not formally examine whether weighting balanced measured covariates between treatment groups. We then proceed to describe a suite of quantitative and qualitative methods that allow one to assess whether measured baseline covariates are balanced between treatment groups in the weighted sample. The quantitative methods use the weighted standardized difference to compare means, prevalences, higher-order moments, and interactions. The qualitative methods employ graphical methods to compare the distribution of continuous baseline covariates between treated and control subjects in the weighted sample. Finally, we illustrate the application of these methods in an empirical case study. We propose a formal set of balance diagnostics that contribute towards an evolving concept of 'best practice' when using IPTW to estimate causal treatment effects using observational data.

    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.

    To test accuracy and reproducibility of tangential breast treatment set-up used in The Netherlands Cancer Institute, a portal imaging study was performed in 12 patients treated for early stage breast cancer. With an on-line electronic portal imaging device (EPID) images were obtained of each patient in several fractions and compared with simulator films and with each other. In 5 patients multiple images (on the average 7) per fraction were obtained to evaluate set-up variations due to respiratory movement. The central lung distance (CLD) and other set-up parameters varied within 1 fraction about 1mm (1SD). The average variation of these parameters between various fractions was about 2 mm (1SD). The differences between simulator and treatment set-up over all patients and all fractions was on the average 2-3mm for the central beam edge to skin distance and CLD. It can be concluded that the tangential breast treatment set-up is very stable and reproducible and that respiration does not have a significant influence on treatment volume. EPID appears to be an adequate tool for studies of treatment set-up accuracy like this. (author). 35 refs.; 2 figs.; 3 tabs.

    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.

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.

    Despite suggestive early findings on the therapeutic use of hallucinogens in the treatment of substance use disorders, rigorous follow-up has not been conducted. To determine the safety and feasibility of psilocybin as an adjunct to tobacco smoking cessation treatment we conducted an open-label pilot study administering moderate (20 mg/70 kg) and high (30 mg/70 kg) doses of psilocybin within a structured 15-week smoking cessation treatment protocol. Participants were 15 psychiatrically healthy nicotine-dependent smokers (10 males; mean age of 51 years), with a mean of six previous lifetime quit attempts, and smoking a mean of 19 cigarettes per day for a mean of 31 years at intake. Biomarkers assessing smoking status, and self-report measures of smoking behavior demonstrated that 12 of 15 participants (80%) showed seven-day point prevalence abstinence at 6-month follow-up. The observed smoking cessation rate substantially exceeds rates commonly reported for other behavioral and/or pharmacological therapies (typically psilocybin, these findings suggest psilocybin may be a potentially efficacious adjunct to current smoking cessation treatment models. The present study illustrates a framework for future research on the efficacy and mechanisms of hallucinogen-facilitated treatment of addiction.

    In this report, we present the results of a single patient with optic neuropathy treated within the Stem Cell Ophthalmology Treatment Study (SCOTS). SCOTS is an Institutional Review Board approved clinical trial and is the largest ophthalmology stem cell study registered at the National Institutes of Health to date-www.clinicaltrials.gov Identifier NCT 01920867. SCOTS utilizes autologous bone marrow-derived stem cells in the treatment of optic nerve and retinal diseases. Pre-and post-treatment comprehensive eye exams were independently performed at the Wilmer Eye Institute at the Johns Hopkins Hospital, USA. A 27 year old female patient had lost vision approximately 5 years prior to enrollment in SCOTS. Pre-treatment best-corrected visual acuity at the Wilmer Eye Institute was 20/800 Right Eye (OD) and 20/4,000 Left Eye (OS). Four months following treatment in SCOTS, the central visual acuity had improved to 20/100 OD and 20/40 OS.

    2011-01-01

    The gene encoding thymidine kinase 1 from tomato (toTK1) has in combination with azidothymidine (AZT) recently been proposed as a powerful suicide gene for anticancer gene therapy. The toTK1/AZT combination has been demonstrated to have several advantages for the treatment of glioblastomas because...... AZT can easily penetrate the blood–brain barrier and toTK1 can efficiently phosphorylate AZT and also AZT-monophosphate. In a pursuit to further understand the properties of toTK1, we examined the oligomerization properties of recombinant toTK1 and its effect on enzyme kinetics. Previously, it has...

  18. Physical Activity during Cancer Treatment (PACT Study: design of a randomised clinical trial

    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. Secondary outcome: health related quality of life (European Organisation Research and Treatment of Cancer-Quality of Life questionnaire-C30, Short Form 36 healthy survey, impact on functioning and autonomy (Impact on functioning and autonomy questionnaire, anxiety and depression (Hospital Anxiety and Depression Scale, physical fitness (aerobic peak capacity, muscle strength, body composition and cognitive-behavioural aspects.

    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 aimed to elicit patient- and treatment-related factors that can potentially predict treatment adherence in adult ADHD. Subjects who were over 18 and received a diagnosis of ADHD were included in the study. 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

    This qualitative study aimed to explore experiences of women currently undergoing specialist inpatient treatment for anorexia nervosa. Interviews were carried out with 21 women with a diagnosis of anorexia nervosa from a specialist adult inpatient eating disorder unit. Five master themes emerged using thematic analysis: (1) shifts in control, (2) experience of transition, (3) importance of supportive staff relationships, (4) sharing with peers and (5) process of recovery and self-discovery. Findings suggest that patients experience a process of change and adjustment in relation to levels of perceived personal control, attachment to the treatment environment and a sense of self-identity.

    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.

    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

    Along with physical and biological changes, a tremendous amount of upheaval and adjustment accompany the pregnancy and postpartum period of a woman's life that together can often result in what is commonly known as postpartum depression. However, anxiety disorders have been found to be more frequent than depression during pregnancy and at least as common, if not more so, during the postpartum period, e.g., Brockington et al., (Archieves Women's Ment Health 9:253-263, 2006; Wenzel et al. (J Anxiety Disord, 19:295-311, 2005). Cognitive-behavioral therapy (CBT) is a well-established psychological treatment of choice for anxiety; however, few studies have specifically examined a cognitive-behavioral intervention targeting perinatal anxiety. This pilot study examined the effectiveness of a cognitive-behavioral group treatment (CBGT) program specifically tailored to address perinatal anxiety in 10 women who were either pregnant or within 12 months postpartum. Participants were recruited from a women's clinic at an academic hospital setting, with anxiety identified as their principal focus of distress. Following a diagnostic interview confirming a primary anxiety disorder and completion of assessment measures, participants completed a 6-week CBGT program. There was a statistically significant reduction in anxiety and depressive symptoms following the CBGT program (all p anxiety. These findings suggest that CBGT for perinatal anxiety is a promising treatment for both anxiety and depressive symptoms experienced during the perinatal period. Further studies are needed to evaluate the treatment efficacy through larger controlled trials. PMID:25652951

    In favourable conditions of low temperature and low oxygen concentration, archaeological waterlogged wooden artefacts, such as shipwrecks, can survive with a good state of preservation. Nevertheless, anaerobic bacteria can considerably degrade waterlogged wooden objects with a significant loss in polysaccharidic components. Due to these decay processes, wood porosity and water content increase under ageing. In such conditions, the conservation treatments of archaeological wooden artefacts often involve the replacement of water with substances which fill the cavities and help to prevent collapse and stress during drying. The treatments are very often expensive and technically difficult, and their effectiveness very much depends on the chemical and physical characteristics of the substances used for impregnation. Also important are the degree of cavity-filling, penetration depth and distribution in the structure of the wood. In this study, the distribution in wood cavities of some mixtures based on polyethylene glycols and colophony, used for the conservation of waterlogged archaeological wood, was investigated using synchrotron radiation X-ray computed microtomography (SR-microCT). This non-destructive imaging technique was useful for the study of the degraded waterlogged wood and enabled us to visualise the morphology of the wood and the distribution of the materials used in the wood treatments. The study has shown how deposition is strictly related to the dimension of the wooden cavities. The work is currently proceeding with the comparison of synchrotron observations with the data of the solutions viscosity and with those of the properties imparted to the wood by the treatments.

    Background Sex addiction is a disorder that can have serious adverse functional consequences. Treatment effectiveness research for sex addiction is currently underdeveloped, and interventions are generally based on the guidelines for treating other behavioral (as well as chemical) addictions. Consequently, there is a need to clinically evaluate tailored treatments that target the specific symptoms of sex addiction. It has been proposed that second-generation mindfulness-based interventions (SG-MBIs) may be an appropriate treatment for sex addiction because in addition to helping individuals increase perceptual distance from craving for desired objects and experiences, some SG-MBIs specifically contain meditations intended to undermine attachment to sex and/or the human body. The current study conducts the first clinical investigation into the utility of mindfulness for treating sex addiction. Case presentation An in-depth clinical case study was conducted involving an adult male suffering from sex addiction that underwent treatment utilizing an SG-MBI known as Meditation Awareness Training (MAT). Following completion of MAT, the participant demonstrated clinically significant improvements in addictive sexual behavior, as well as reductions in depression and psychological distress. The MAT intervention also led to improvements in sleep quality, job satisfaction, and non-attachment to self and experiences. Salutary outcomes were maintained at 6-month follow-up. Discussion and conclusion The current study extends the literature exploring the applications of mindfulness for treating behavioral addiction, and findings indicate that further clinical investigation into the role of mindfulness for treating sex addiction is warranted.

    The most common data structures in the biomedical studies have been matched or unmatched designs. Data structures resulting from a hybrid of the two may create challenges for statistical inferences. The question may arise whether to use parametric or nonparametric methods on the hybrid data structure. The Early Treatment for Retinopathy of Prematurity study was a multicenter clinical trial sponsored by the National Eye Institute. The design produced data requiring a statistical method of a hybrid nature. An infant in this multicenter randomized clinical trial had high-risk prethreshold retinopathy of prematurity that was eligible for treatment in one or both eyes at entry into the trial. During follow-up, recognition visual acuity was accessed for both eyes. Data from both eyes (matched) and from only one eye (unmatched) were eligible to be used in the trial. The new hybrid nonparametric method is a meta-analysis based on combining the Hodges-Lehmann estimates of treatment effects from the Wilcoxon signed rank and rank sum tests. To compare the new method, we used the classic meta-analysis with the t-test method to combine estimates of treatment effects from the paired and two sample t-tests. We used simulations to calculate the empirical size and power of the test statistics, as well as the bias, mean square and confidence interval width of the corresponding estimators. The proposed method provides an effective tool to evaluate data from clinical trials and similar comparative studies. PMID:23839782

    Background Restylane, a hyaluronic acid gel, has been widely used as a dermal filler in USA and European countries. This study was designed to study the safety and efficacy of Restylane as a non-permanent dermal filler for facial augmentation therapy in China for the correction of nasolabial folds during a follow-up period of 6 months. Methods The study consisted of a screening visit, a baseline visit during which injection with Restylane was given, and follow-up visits after four weeks, three months and six months. The efficacy was subjectively assessed by comparing the treatment results between pre-treatment and post-treatment. Adverse events were analyzed by severity and duration. Results At six months post-baseline, the subjects and the investigators' independent assessment score of Wrinkle Severity Rating Scale was decreased. Global Aesthetic Improvement Scale was considered to have improved by over 90% in some cases. Adverse events related to product and injection was reported in 21.5% of the injections. A vast majority of the post-treatment reactions were mild. Conclusions The efficacy of Restylane for nasolabial fold in a Chinese population was excellent. Restylane was well tolerated and no systemic reactions or other safety concerns were raised.

  5. Study of argon plasma treatment of polycarbonate substrate and its effect on film deposition

    International Nuclear Information System (INIS)

    Results of polycarbonate plasma treatment in argon r.f. glow discharges as concern the chemical structure and surface free energy are presented. The oxygen-to-carbon ratio increased after the treatment indicating an increase of oxygen containing functional groups on the polycarbonate surface. Small amount of silicon as a result of previous depositions of organosilicon thin films in the same reactor and small amount of nitrogen coming probably from an exposure of the reactive surface to the atmosphere were found on the surface. The surface free energy increased after the treatment from the original value of 35 mJ/m2 to 63-74 mJ/M2. Effect of treatment time, gas flow rate, pressure and aging on the surface free energy was studied too. In order to study an improvement of adhesion between between the polycarbonate and an additional coatings the organosilicon thin films were deposited on the untreated and plasma treated polycarbonate. The interfacial fracture resistance of such a system was qualitatively tested by cross-hatch peel test. The initiation and propagation stage of the fracture were studied by depth sensing indentation method followed by an observation of the samples with an optical microscope (Authors)

    Although the mechanism of laser stimulation effect in bone has not completely understood, laser stimulation is recommended in the treatment of osteoporosis due to positive treatment efficacy. In this study, a minimal invasive laser needle system (MILNS) was developed using a fine hollow needle in order to stimulate directly bone site by guiding an optical fiber. In order to evaluate the MILNS as a treatment method, in-vivo animal experiment study was performed using osteopenic mice. Twelve virginal ICR mice were employed and divided two groups: SHAM-group and LASERgroup. SHARM-group was stimulated by only fine hollow needle and LASER-group by fine hollow needle combined with laser stimulation. All mice were served in-vivo micro-CT images before and after treatment. Three dimensional (3D) structural parameters and vBMD (volume bone mineral density, g/cm3) in the trabecular bone were measured. After 2 weeks of stimulation, the vBMD, BV/TV, Tb.Th and Tb.N in LASER-group were significantly higher than those in SHAM-group (p<0.05). Potentially, this study suggested that the MILNS might prevent the bone loss and maintains the bone mineral density of osteopenic mice.

    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.

    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

    AIM: To compare the effectiveness of topical cyclosporine A emulsion with that of oral doxycycline for rosacea associated ocular changes and dry eye complaints.METHODS: One hundred and ten patients with rosacea were screened. Thirty-eight patients having rosacea associated eyelid and ocular surface changes and dry eye complaints were included in the study. Patients were randomly divided into two groups: nineteen patients were given topical cyclosporine twice daily and nineteen patients were given oral doxycycline 100 mg twice daily for the first month and once daily for the following two months. Symptom and sign scores, ocular surface disease index questionnarie and tear function tests were evaluated at baseline and monthly for 3mo. Three months after results were compared with that of baseline.RESULTS: Mean values of symptom, eyelid sign and corneal/conjunctival sign scores of each treatment group at baseline and 3mo after treatments were compared and both drugs were found to be effective on rosacea associated ocular changes(P <0.001). Cyclosporine was more effective in symptomatic relief and in the treatment of eyelid signs(P =0.01). There was statistically significant increase in the mean Schirmer score with anesthesia and tear break up time scores in the cyclosporine treatment group compared to the doxycycline treatment group(P <0.05).CONCLUSION: Cyclosporine as a topical drug can be used in the treatment of rosacea associated ocular complications because it is more effective than doxycycline. In addition ocular rosacea as a chronic disease requires long term treatment and doxycycline has various side effects limiting its long term usage.

    Objective Evaluation of the efficacy of pancreatic resections for the treatment of chronic pains during chronic pancreatitis. Methods Retrospective study of inpatients for chronic pancreatitis between 1982 to 2000. Purpose of admission, morphological changes, treatments and results were evaluated. Results 142 patients were admitted for chronic pancreatitis. 111 patients suffered from chronic pains, due to morphological changes such as pseudocysts, inflammatory masses in the head, dilated pancreatic ducts, biliary or duodenal compressions. Denervations were never efficient, pancreatic resections achieved relief of pain in up to 75% of cases and drainages were efficient in 52% of cases. Conclusions Pancreatic resections during chronic pancreatitis seem to be the most efficient treatment of chronic pains. New techniques such as duodenum-preserving head resection or total pancreatectomy with islet autotransplantation should improve these results.

    Grey water has long been considered a promising option for dealing with water scarcity and reuse. However, factors such as lack of macronutrients and low carbon content make its treatment challenging. The aim of this paper was to investigate the applicability of sequencing batch reactor (SBR) technology to on-site grey water treatment at a sports centre for reuse in irrigation. The results demonstrated that the regenerated water complied with microbiological parameters concerning restriction of solids and organic matter removal. Denitrification was not fully accomplished, but ammonium was totally oxidised and low concentrations of nitrates were achieved. Effluent with good appearance and no odour was used in an experimental study to irrigate a grid system containing natural and artificial grass sections. The conclusion is that SBR technology offers a promising treatment for grey water. PMID:24191471

    Music festivals and other temporary events, such as bicycle races, lay a heavy burden on the surrounding environment. Treatment of the wastewater originating from such events is necessary if no municipal treatment plant is available. This study demonstrated that activated carbon is a performant technique for the treatment of wastewaters originating from these temporary events. Freundlich isotherms and maximum operational linear velocity (6 m/h) were determined on a lab-scale set-up. A pilot-scale set up was used to treat part (5%) of the total volume of the Dranouter Music Festival shower wastewater. On average 90% removal of COD and suspended solids concentration was obtained. Application of the activated carbon filter resulted in the fact that the local discharge limits were met without operational problems.

    Full Text Available "nAs the most common male sexual disorder premature ejaculation (PE, also referred to as early ejaculation (EE or rapid ejaculation (RE, affects 30%-40% of sexually active men. Despite the limited number of available studies comparing the efficacy of selective serotonin re-uptake inhibitors (SSRI they have been thought to have beneficial effects for the treatment of patients with PE. In the present study, we assessed the efficacy of on-demand use of citalopram, in the treatment of premature ejaculation. A randomized double blind study of fixed dose on-demand use of citalopram was performed in Roozbeh Psychiatry Hospital, Tehran University of Medical Sciences. The sample was consisted of 80 married patients diagnosed with PE according to Diagnostic and Statistical Manual of Mental Disorders. The patients were randomly assigned to two groups: group 1 consisting of 42 patients received 20mg citalopram, and group 2 consisting of 38 patients received placebo four hours before intercourse for a 4-week treatment course. The effects of drug on the ejaculatory function in each group were assessed by the intravaginal ejaculation latency time (IELT, and the Chinese Index of Premature Ejaculation (CIPE before and at the end of treatment course. The mean IELT increased from 66.78±36.94 to 80.85±43.05 seconds in group 1 and from 63.44±33.16 to 65.71±34.26 seconds in group 2 (P = 0.000. Mean CIPE score increased 1.14±1.04 and 0.52±0.50 in group 1 and 2 respectively (P = 0.002. The patients treated with on demand citalopram showed significantly greater improvement in IELT and CIPE score compared to the patients receiving placebo. It seems that citalopram may be an effective treatment of premature ejaculation with on-demand usage. However further studies are warranted.

  20. Gamma Knife Treatment of Growing Vestibular Schwannoma in Norway: A Prospective Study

    International Nuclear Information System (INIS)

    Purpose: Gamma Knife radiosurgery (GKRS) has been increasingly used in the treatment of vestibular schwannoma (VS). Very few studies relate tumor control and post-treatment growth rates to pretreatment growth rates. Methods and Materials: We prospectively included 45 consecutive VS patients who were initially treated conservatively and then received GKRS between 2000 and 2007 because of demonstrated tumor growth. Pretreatment and post-treatment tumor volumes were estimated. Patients underwent audiograms, reported their symptoms, and responded to the Short Form General Health Survey (SF-36) questionnaire on each visit. Results: Volume doubling times before and after treatment were 1.36 years (95% confidence intervals, 1.14-1.68) and −13.1 years (95% confidence intervals, −111.0 to −6.94), respectively. Tumor control, defined as a post-GKRS growth rate ≤0, was achieved in 71.1% of patients, with highest odds for tumor control among older patients and those with larger tumors. The 5-year retreatment-free survival rate was 93.9% (95% confidence intervals, 76.5-98.5). None of the clinical endpoints investigated showed statistically significant changes after GKRS, but improvement was seen in a few SF-36 parameters. Conclusions: GKRS alters the natural course of the tumor by reducing growth. Mathematic models yield poorer tumor control rates than those found by clinical assessment. Symptoms were unaffected by treatment, but quality of life was improved.

    Since the beginning of the 1990s, local authorities in Israel have been engaged in promoting advanced Wastewater Treatment Plant (WWTP) projects throughout the country, resulting in the "wastewater treatment revolution" of the 1990s. These achievements are extremely important in the water-scarce country, as untreated or partially treated wastewater has become a major source of pollution of Israel's fresh-water resources, and reuse of high-quality effluents can expand the national water potential. Many of these projects are regional schemes based on a central WWTP, serving a few neighboring municipalities. This paper presents two case studies of such regional cooperation: the "Karmiel Region Union of Towns for Sewage Treatment" and the "Treatment and Reuse of Wastewater in the area of the Hadera Stream, Ltd." corporation. The findings suggest that regional cooperation can be an efficient tool in promoting advanced wastewater treatment, and has several advantages: an efficient use of limited resources (financial and land); balancing disparities between municipalities (size, socio-economic features, consciousness and ability of local leaders); and reducing spillover effects. However, some problems were reported in both cases and should be addressed. PMID:17335957

    Evaluations by patients constitute an important part of the process of improving health services. This study examined patients’ perceptions of secondary dental care in three cities in Minas Gerais, Brazil based on the endodontic treatment received. Data were collected using semi-structured interviews (addressing access, treatment and results) and a field diary (direct observations and report of professionals). The interviews were audiotaped, fully transcribed, and analyzed using content analysis. Two principal themes were identified: access to service and quality of service. The difficulties in accessing service were associated with the insufficient number of professionals to meet the high demand for endodontic treatment, problems in referring from primary to secondary care and geographic barriers. Service quality was related to the presence/absence of pain and anxiety that patients experienced, the time and number of sessions required to complete treatment, how patients were treated by dentists, and whether those patients would recommend the service to other patients. Access to endodontic treatment was a problem emphasized by users, and satisfaction with the quality of the service was more related to how patients were treated than to the technical competence of the dentist.

    Full Text Available Introduction: Endodontic treatment of young permanent teeth with incomplete root formation and necrotic pulp has been a challenge for the dentist. It is necessary to induce the formation of apical barrier (apical plug, enabling the complete root canal filling. Objective: This retrospective clinical study compared the protocols for treatment of teeth with incomplete root formation, using calcium hydroxide (CH or mineral trioxide aggregate (MTA. Material and methods: 28 patients with incomplete root formation have undergone root canal treatments in the period from 2000 to 2009 were selected. The procedures for cleaning, shaping and intracanal medication (CH paste were performed in a standardized manner. In 13 patients, after using the CH paste (14 days, apical plugs with MTA were made. In the remaining 15 teeth monthly exchanges with CH paste were executed until it was observed radiographically the formation of the apical barrier. In all cases the canals were filled conventionally with gutta-percha and sealer. Initially, follow-ups were made on a quarterly and semiannually at the end of first year. Results: All apical lesions showed apical healing between 4 and 13 months after starting treatment. There was not noted the continuing process of root formation. Conclusion: It was concluded that the treatment of teeth with incomplete root formation and necrotic pulp with the use of MTA as apical plug has the same clinical results compared with the use of CH, with the advantage of less clinical time.

    Purpose: Gamma Knife radiosurgery (GKRS) has been increasingly used in the treatment of vestibular schwannoma (VS). Very few studies relate tumor control and post-treatment growth rates to pretreatment growth rates. Methods and Materials: We prospectively included 45 consecutive VS patients who were initially treated conservatively and then received GKRS between 2000 and 2007 because of demonstrated tumor growth. Pretreatment and post-treatment tumor volumes were estimated. Patients underwent audiograms, reported their symptoms, and responded to the Short Form General Health Survey (SF-36) questionnaire on each visit. Results: Volume doubling times before and after treatment were 1.36 years (95% confidence intervals, 1.14-1.68) and -13.1 years (95% confidence intervals, -111.0 to -6.94), respectively. Tumor control, defined as a post-GKRS growth rate {<=}0, was achieved in 71.1% of patients, with highest odds for tumor control among older patients and those with larger tumors. The 5-year retreatment-free survival rate was 93.9% (95% confidence intervals, 76.5-98.5). None of the clinical endpoints investigated showed statistically significant changes after GKRS, but improvement was seen in a few SF-36 parameters. Conclusions: GKRS alters the natural course of the tumor by reducing growth. Mathematic models yield poorer tumor control rates than those found by clinical assessment. Symptoms were unaffected by treatment, but quality of life was improved.

    Substance-dependent patients (N=29) living with a family member other than a spouse were randomly assigned to equally intensive treatments consisting of either (a) Behavioral Family Counseling (BFC) plus Individual-Based Treatment (IBT) or (b) IBT alone. Outcome data were collected at baseline, post-treatment, and at 3- and 6-month follow-up. BFC patients remained in treatment significantly longer than IBT patients. BFC patients improved significantly from baseline at all time periods on all outcomes studied, and had a medium effect size reflecting better primary outcomes of increased abstinence and reduced substance use than IBT patients. For secondary outcomes of reduced negative consequences and improved relationship adjustment, both BFC and IBT patients improved significantly and to an equivalent extent. The present results show BFC is a promising method for retaining patients in treatment, increasing abstinence, and reducing substance use. These results also provide support for larger scale, randomized trials examining the efficacy of behavioral family counseling for patients living with family members beyond spouses.

    Objective There are quite a few researches about SSRIs and alpha-receptor blockers on the treatment of premature ejaculation (PE), but few researches focus on the combination use of them. In this study, we evaluate the efficacy and safety of combine and alone use of paroxetine hydrochloride and tamsulosin on the treatment of lifelong PE. Methods 352 cases of men with 18–65 years of age, a history of lifelong PE and an intra-vaginal ejaculation latency time (IELT) premature ejaculation profile (PEP), the adverse events (AEs) and vital sign measurements were recorded at each visit. All the data were statistically analyzed. Results The reliable data from 322 patients were achieved. The geometric mean IELT in group A was significantly increased from 1.15 to 8.13 min after treatment (Pejaculation, satisfaction with sexual intercourse, ejaculation-related personal distress, and ejaculation-related interpersonal difficulty were significantly improved in all groups after treatment (P<0.001). The mean PEP scores in group C have more significant improvements than that in group A and B (P<0.01). The prevalence of AEs in group A, B, C were 9.26% (10 cases), 3.81% (4 cases) and 8.26% (9 cases), respectively. Conclusions Paroxetine hydrochloride combined with tamsulosin produce more better therapeutic effects than use them separately. It could be a priority for the treatment of lifelong PE.

    Elevated proportions of Candida albicans in biofilms formed on dentures are associated with stomatitis whereas Streptococcus mutans accumulation on restorative materials can cause secondary caries. Candida albicans, S. mutans, saliva-derived and C. albicans/saliva-derived mixed biofilms were grown on different materials including acrylic denture, porcelain, hydroxyapatite (HA), and polystyrene. The resulting biomass was analysed by three-dimensional image quantification and assessment of colony-forming units. The efficacy of biofilm treatment with a dissolved denture cleansing tablet (Polident(®)) was also evaluated by colony counting. Biofilms formed on HA exhibited the most striking differences in biomass accumulation: biofilms comprising salivary bacteria accrued the highest total biomass whereas C. albicans biofilm formation was greatly reduced on the HA surface compared with other materials, including the acrylic denture surface. These results substantiate clinical findings that acrylic dentures can comprise a reservoir for C. albicans, which renders patients more susceptible to C. albicans infections and stomatitis. Additionally, treatment efficacy of the same type of biofilms varied significantly depending on the surface. Although single-species biofilms formed on polystyrene surfaces exhibited the highest susceptibility to the treatment, the most surviving cells were recovered from HA surfaces for all types of biofilms tested. This study demonstrates that the nature of a surface influences biofilm characteristics including biomass accumulation and susceptibility to antimicrobial treatments. Such treatments should therefore be evaluated on the surfaces colonized by the target pathogen(s).

    The permissibility and lawfulness of withdrawing and withholding medical treatment has attracted considerable debates and criticisms, as the legal issues are drawn into entering the slippery slope of euthanasia. Proponents of "sanctity of life" views that withdrawing and withholding medical treatment with knowledge that death would result is still within the sphere of euthanasia, whereas proponents of "quality of life" argue that it is not, as death is not intended. Their arguments maintain that for patients who are totally dependant on machines to ensure the work of some bodily functions, living may amount to little more than survival as dying is prolonged. Furthermore, the prolonging of life of the dying patient has profound implications on patients themselves, their relatives, dependants and medical providers. Thus, withdrawing and withholding medical treatment would not only respect a patient's right to self-determination, by allowing them to die in their underlying condition, but will ensure that medical providers are able to concentrate on more worthwhile treatments. This paper discusses the intractable difficulties with the moral distinction between withholding and withdrawing treatment and euthanasia, as well as makes a comparative study between the present state of law in Malaysia and England on this issue. The paper further highlights the differences between civil law and Islamic law in this controversial area.

    In noninvasive abdominal tumor treatment, research has focused on minimizing organ motion either by gating, breath holding or tracking of the target. The paradigm shift proposed in this study takes advantage of the respiratory organ motion to passively scan the tumor. In the proposed self-scanning method, the focal point of the HIFU device is held fixed for a given time, while it passively scans the tumor due to breathing motion. The aim of this paper is to present a treatment planning method for such a system and show by simulation its feasibility. The presented planning method minimizes treatment time and ensures complete tumor ablation under free-breathing. We simulated our method on realistic motion patterns from a patient specific statistical respiratory model. With our method, we achieved a shorter treatment time than with the gold-standard motion-compensation approach. The main advantage of the proposed method is that electrically steering of the focal spot is no longer needed. As a consequence, it is much easier to find an optimal solution for both avoiding near field heating and covering the whole tumor. However, the reduced complexity on the beam forming comes at the price of an increased complexity on the planning side as well as a reduced efficiency in the energy distribution. Although we simulate the approach on HIFU, the idea of self-scanning passes over to other tumor treatment modalities such as proton therapy or classical radiation therapy.

    Full Text Available We examined whether pain outcomes (pain interference, perceived pain treatment effectiveness vary by race and then whether opioid use moderates these associations. These analyses are part of a retrospective cohort study among 3,505 black and 46,203 non-Hispanic, white Department of Veterans Affairs (VA patients with diagnoses of chronic musculoskeletal pain who responded to the 2007 VA Survey of Healthcare Experiences of Patients (SHEP. We used electronic medical record data to identify prescriptions for pharmacologic pain treatments in the year after diagnosis (Pain Diagnosis index visit and before the SHEP index visit (the visit that made one eligible to complete the SHEP; pain outcomes came from the SHEP. We found no significant associations between race and pain interference or perceived effectiveness of pain treatment. VA patients with opioid prescriptions between the Pain Diagnosis index visit and the SHEP index visit reported greater pain interference on the SHEP than those without opioid prescriptions during that period. Opioid prescriptions were not associated with perceived treatment effectiveness for most patients. Findings raise questions about benefits of opioids for musculoskeletal pain and point to the need for alternative treatments for addressing chronic noncancer pain.

    Full Text Available Abstract Background Greater understanding of the variance in the number of consultations per dietetic treatment will increase the transparency of dietetic healthcare. Substantial inter-practitioner variation may suggest a potential to increase efficiency and improve quality. It is not known whether inter-practitioner variation also exists in the field of dietetics. Therefore, the aims of this study are to examine inter-practitioner variation in the number of consultations per treatment and the case-mix factors that explain this variation. Methods For this observational study, data were used from the National Information Service for Allied Health Care (LiPZ. LiPZ is a Dutch registration network of allied health care professionals, including dietitians working in primary healthcare. Data were used from 6,496 patients who underwent dietetic treatment between 2006 and 2009, treated by 27 dietitians working in solo practices located throughout the Netherlands. Data collection was based on the long-term computerized registration of healthcare-related information on patients, reimbursement, treatment and health problems, using a regular software program for reimbursement. Poisson multilevel regression analyses were used to model the number of consultations and to account for the clustered structure of the data. Results After adjusting for case-mix, seven percent of the total variation in consultation sessions was due to dietitians. The mean number of consultations per treatment was 4.9 and ranged from 2.3–10.1 between dietitians. Demographic characteristics, patients’ initiative and patients’ health problems explained 28% of the inter-practitioner variation. Certain groups of patients used significantly more dietetic healthcare compared to others, i.e. older patients, females, the native Dutch, patients with a history of dietetic healthcare, patients who started the treatment on their own initiative, patients with multiple diagnoses, overweight

    Different pharmacologic agents have been evaluated in the treatment of Chronic Fatigue Syndrome (CFS), albeit with moderate efficacy. Among the compounds thought to present with potential to be efficacious in CFS patients stands out low-dose amisulpride, a substituted benzamide that has been shown to be an useful treatment for conditions which exhibit some overlap with CFS such as dysthymia and somatoform disorders. We thus recruited forty non-depressed CFS patients that were randomized to receive either amisulpride 25mg bid, or fluoxetine 20mg uid; all subjects were un-blinded to the treatment regimen. At the time of enrollment in the study and after twelve weeks of treatment, enrolled subjects completed the Krupp Fatigue Severity Scale, the Hospital Anxiety and Depression Scale and a visual analog scale focused on pain and bodily discomfort. Moreover, all subjects were evaluated by a clinician, blinded to the treatment regimen, using the Clinical Global Impression Severity Scale. Our data revealed a significant improvement both in self-report, and observer-based measures for the amisulpride-treated, but not for the fluoxetine-treated patients. Amisulpride-treated subjects also presented with a significant reduction of somatic complaints, while the amisulpride effect on anxiety and mood levels was not significant. Both drugs were equally well tolerated. Summing up, we showed a positive symptomatic effect of amisulpride, compared to SSRI treatment, in a group of non-depressed CSF patients on self-report and on observer-based measures of fatigue and somatic complaints. If confirmed by larger, blinded studies, amisulpride thus could represent an effective approach to this difficult-to-treat condition.

    Thermal treatment or hyperthermia has received considerable attention in recent years due to its high efficiency, safety and relatively few side-effects. In this study, we investigated whether it was possible to utilize targeted thermal or instent thermal treatments for the treatment of restenosis following percutaneous transluminal coronary angioplasty (PTCA) through magnetic stent hyperthermia (MSH). A 316L stainless steel stent and rabbit vascular smooth muscle cells (VSMCs) were used in the present study, in which the inductive heating characteristics of the stent under alternative magnetic field (AMF) exposure, as well as the effect of MSH on the proliferation, apoptosis, cell cycle and proliferating cell nuclear antigen (PCNA) expression of the rabbit VSMCs, were evaluated. The results demonstrated that 316L stainless steel coronary stents possess ideal inductive heating characteristics under 300 kHz AMF exposure. The heating properties were shown to be affected by the field intensity of the AMF, as well as the orientation the stent axis. MSH had a significant effect on the proliferation and apoptosis of VSMCs, and the effect was temperature-dependent. While a mild temperature of 43°C demonstrated negligible effects on the growth of VSMCs, MSH treatment above 47°C effectively inhibited the VSMC proliferation and induced apoptosis. Furthermore, a 47°C treatment exhibited a significant and long-term inhibitory effect on VSMC migration. The results strongly suggested that MSH may be potentially applied in the clinic as an alternative approach for the prevention and treatment of restenosis. PMID:24137187

    Shock wave lithotripsy (SWL) is the gold standard for the treatment of upper urinary tract stones. Despite being relatively non-invasive, SWL can cause renal hematoma (RHT). The aim of this study was to determine incidence and risk factors for RHT following SWL. 857 patients were included in a prospectively maintained database. The observation period spans from 2007 to 2012. 1,324 procedures were performed due to kidney stones. Treatment protocol included power ramping and shock wave frequency of 60-90 per minute as well as an ultrasound check within 3 days of SWL for all patients. Patients with RHT were analyzed, and treatment characteristics were compared with the complete population in a non-statistical manner due to the low event count. RHTs after SWL, sized between 2.6 × 0.6 cm and 17 × 15 cm, were verified in seven patients (0.53%). In four patients, the RHT was asymptomatic. Three patients developed pain after SWL treatment due to a RHT. In one patient surgical intervention was necessary due to a symptomatic RHT, the kidney was preserved. The risk of RHT following SWL treatment of kidney stones is about 0.5%. Clinically relevant or symptomatic RHTs occur in 0.23%, RHTs requiring surgical intervention are extremely rare. Older age and vascular comorbidities appear to be risk factors for the development of RHT. The technical characteristics of SWL treatment and intake of low-dose acetylsalicylic acid due to an imperative cardiologic indication do not appear to influence the risk. Prospective studies are warranted. PMID:24419328

    Methadone maintenance treatment (MMT) has become an important modality of substitution treatment for opioid addicts in China since 2006. However, data are limited regarding the change in sexual function from heroin use to MMT and the influence of sexual dysfunction (SD) during MMT on patient's life and treatment. Face-to-face in-depth interviews were conducted with 13 male and 14 female MMT patients, five of their partners, and three clinicians. The interviews took place in four MMT clinics in Guangdong Province between August 2010 and February 2011. The patients and their partners were asked separately for their perceptions of patient's sexual function during MMT, and the influence of SD on personal/family life and treatment. The main SD problems patients perceived were libido inhibition and decreased sexual pleasure. Methadone was thought to have a stronger inhibition effect on sexual desire than heroin. SD decreased quality of patient's sexual life and damaged intimate relationships. There was a gender difference in coping with SD. Men generally tended to refuse, escape, or alienate their partners. Women tended to hide sexual listlessness, endure sexual activity and tried to satisfy their partners. SD might increase risk of voluntary dropout from treatment and illicit drug use during treatment. Patients with SD did not get any effective therapy from clinicians and they also lacked skills on coping with SD-related problems. Sexual dysfunction prevented patients from reconstructing a normal intimate relationship, and affected stability of maintenance treatment. Response to patient's SD and SD-related problems from clinicians was inadequate. There is a need to develop a clinical guide to deal with both SD itself and SD-related problems. PMID:23092392

  19. A treatment planning study comparing Elekta VMAT and fixed field IMRT using the varian treatment planning system eclipse

    International Nuclear Information System (INIS)

    The newest release of the Eclipse (Varian) treatment planning system (TPS) includes an optimizing engine for Elekta volumetric-modulated arc therapy (VMAT) planning. The purpose of this study was to evaluate this new algorithm and to compare it to intensity-modulated radiation therapy (IMRT) for various disease sites by creating single- and double-arc VMAT plans. A total of 162 plans were evaluated in this study, including 38 endometrial, 57 head and neck, 12 brain, 10 breast and 45 prostate cancer cases. The real-life IMRT plans were developed during routine clinical cases using the TPS Eclipse. VMAT plans were generated using a preclinical version of Eclipse with tumor-region-specific optimizing templates without interference of the operator: with one full arc (1A) and with two full arcs (2A), and with partial arcs for breast and prostate with hip implant cases. All plans were evaluated based on target coverage, homogeneity and conformity. The organs at risk (OARs) were analyzed according to plan objectives, such as the mean and maximum doses. If one or more objectives were exceeded, the plan was considered clinically unacceptable, and a second VMAT plan was created by adapting the optimization penalties once. Compared to IMRT, single- and double-arc VMAT plans showed comparable or better results concerning the target coverage: the maximum dose in the target for 1A is the same as that for IMRT; for 2A, an average reduction of 1.3% over all plans was observed. The conformity showed a statistically significant improvement for both 1A (+3%) and 2A (+6%). The mean total body dose was statistically significant lower for the considered arc techniques (IMRT: 16.0 Gy, VMAT: 15.3 Gy, p < 0.001). However, the sparing of OARs shows individual behavior that depends strongly on the different tumor regions. A clear difference is found in the number of monitor units (MUs) per plan: VMAT shows a reduction of 31%. These findings demonstrate that based on optimizing templates with
