    Full Text Available Abstract Patients with type 2 diabetes mellitus (T2DM are at high risk for cardiovascular (CV disease; however, conclusive evidence that glycemic control leads to improved cardiovascular outcomes is lacking. Saxagliptin is a potent, selective dipeptidyl peptidase-4 inhibitor approved as an adjunct to diet and exercise to improve glycemic control in adults with T2DM. Saxagliptin was evaluated in a series of phase III trials as monotherapy; add-on therapy to metformin, a sulfonylurea, or a thiazolidinedione; and as initial therapy in combination with metformin. Saxagliptin consistently improved glycemic control (as reflected by significant decreases in glycated hemoglobin, fasting plasma glucose, and postprandial glucose compared with controls and was generally well tolerated. In these analyses, saxagliptin had clinically neutral effects on body weight, blood pressure, lipid levels, and other markers of CV risk compared with controls. A retrospective meta-analysis of 8 phase II and phase III trials found no evidence that saxagliptin increases CV risk in patients with T2DM (Cox proportional hazard ratio, 0.43; 95% CI, 0.23-0.80 for major adverse cardiovascular events retrospectively adjudicated. Instead, it raised the hypothesis that saxagliptin may reduce the risk of major adverse CV events. A long-term CV outcome trial, Saxagliptin Assessment of Vascular Outcomes Recorded in Patients with Diabetes Mellitus-THrombolysis in Myocardial Infarction 53 (SAVOR-TIMI 53 is currently ongoing to determine whether saxagliptin reduces CV risk in T2DM.

In patients with T2DM, once-daily administration of saxagliptin before breakfast achieves sustained inhibition of plasma DPP-4 activity and reduction of postprandial hyperglycemia, including after dinner, associated with an increase in plasma glucagon-like peptide-1 levels. This paper reviews the safety and efficacy of saxagliptin in Japanese patients with T2DM. The clinical development study in Japan supported its usefulness for the disease. Saxagliptin 1, 2.5, and 5 mg led to significant improvements in glycated hemoglobin (HbA1c, and was generally well tolerated. Treatment with saxagliptin 5 mg induced a sustained reduction in HbA1c over 52 weeks. Long-term combination therapy with saxagliptin and other oral hypoglycemic agents also provided sustained glycemic control and was well tolerated for up to 52 weeks. Saxagliptin as add-on to sulfonylureas or glinides has a tendency to increase hypoglycemia, but not with other oral antidiabetic agents, such as α-glucosidase inhibitors, metformin, or thiazolidinediones. The results of clinical trials have confirmed the long-term efficacy and safety of saxagliptin monotherapy as

    Full Text Available Abstract Background The aim of this study was to assess efficacy and safety of saxagliptin monotherapy for up to 76 weeks in patients with type 2 diabetes mellitus (T2DM and inadequate glycemic control, with main efficacy assessment at 24 weeks. Methods 365 treatment-naïve patients with T2DM (HbA1c 7.0%–10.0% were treated with saxagliptin 2.5 mg q.A.M., saxagliptin 2.5 mg q.A.M. with possible titration to saxagliptin 5 mg, saxagliptin 5 mg q.A.M., saxagliptin 5 mg q.P.M., or placebo. After week 24, patients in all groups were eligible for titration to saxagliptin 10 mg based on HbA1c ≥7%, and all unrescued placebo patients began blinded metformin 500 mg/day. Rescue with open-label metformin was available for patients with inadequate glycemic control. Results At week 24, placebo-subtracted mean HbA1c reduction from baseline (LOCF was significantly greater in the saxagliptin treatment groups vs placebo, and remained greater through week 76. Serious adverse events (AEs and discontinuations due to AEs were similar in saxagliptin and control groups; incidence of confirmed hypoglycemia was low across all treatment groups (saxagliptin-treated, 2 [0.7]; control, 1 [1.4]. Conclusions In treatment-naïve patients with T2DM, saxagliptin monotherapy demonstrated statistically significant improvement in HbA1c compared with placebo at 24 weeks and was generally well tolerated for up to 76 weeks.

    Full Text Available Antonio R Chacra, MDDiabetes Center, Federal University of São Paulo, BrazilAbstract: Saxagliptin (Onglyza™ is a potent, selective, once-daily dipeptidyl peptidase-4 (DPP-4 inhibitor indicated for improving glycemic control in patients with type 2 diabetes (T2D. By blocking DPP-4, saxagliptin increases and prolongs the effects of incretins, a group of peptide hormones released by intestinal cells after meals, which stimulate glucose-dependent insulin secretion to lower blood glucose. In controlled clinical trials, saxagliptin administered as monotherapy or in combination with metformin, glyburide, or a thiazolidinedione improved glycemic control in a clinically significant manner, reflected by significant decreases in glycated hemoglobin (monotherapy, -0.5%; add-on to metformin, thiazolidinedione, or sulfonylurea, -0.6% to 0.9%; initial combination with metformin, -2.5%, fasting plasma glucose, and postprandial glucose compared with controls. Additionally, saxagliptin improved β-cell function, reflected as increases in homeostasis model assessment (HOMA-2β. Saxagliptin was generally well tolerated; it did not increase hypoglycemia compared with controls, and was weight neutral. A meta-analysis of Phase II and III trials showed that saxagliptin did not increase the risk of major cardiovascular events. Professional organizations have updated their guidelines for T2D to include a DPP-4 inhibitor as an early treatment option—either as initial therapy in combination with metformin, or as add-on therapy for patients whose glycemia is inadequately controlled by a single oral antidiabetic drug.Keywords: saxagliptin, dipeptidyl peptidase-4 (DPP-4 inhibitor, type 2 diabetes

    Full Text Available Baptist GallwitzDept Medicine IV, Tübingen University, Otfried-Müller-Str, 10, 72076 Tübingen, GermanyAbstract: Saxagliptin is a novel dipeptidyl peptidase-4 inhibitor (DPP-4 inhibitor for the treatment of type 2 diabetes, with a duration profile for once daily dosing. It is highly selective for DPP-4 in comparison to other enzymes of the dipeptidyl peptidase family. DPP-4 inhibitors elevate plasma concentrations of the incretin hormones glucagon-like peptide-1 (GLP-1 and gastric inhibitory polypeptide (GIP. This effect results in a glucose-dependent stimulation of insulin secretion and an inhibition of glucagon secretion without an intrinsic risk for hypoglycemia. In comparison to sulfonylureas and thiazolidinediones that promote weight gain, DPP-4 inhibitors are weight neutral. Saxagliptin has been approved by the FDA for the US and by the EMEA for Europe in 2009. Clinical trials showed a dose-dependent inhibition of DPP-4 by saxagliptin in doses ranging from 2.5 to 100 mg daily without serious side effects. Type 2 diabetic patients receiving 5 mg to 10 mg saxagliptin once daily had a significant lowering of HbA1c and glycemic parameters along with good tolerability and safety. Saxagliptin has demonstrated a good efficacy for glycemic parameters in various patient populations either in monotherapy or in combination with metformin and other oral antidiabetic drugs as well as a favorable cardiovascular profile. With its high selectivity for DPP-4 and its clinical and cardiovascular profile, saxagliptin is an attractive novel DPP-4 inhibitor.Keywords: type 2 diabetes, diabetes therapy, DPP-4 inhibitors, incretin based therapy, GLP-1, saxagliptin

    Full Text Available Objective: To determine in Colombia, the cost effectiveness ratio of the saxagliptin or sulphonylureas addition to patients with T2DM who fail to achieve glycemic goals with metformin, for a maximum period of 20 years. Methods: We performed a cost effectiveness analysis, using a discrete event simulation model with fixed time step (Cardiff Diabetes Model. The characteristics of the cohort of patients and efficacy profile for each treatment were obtained from the literature. The cost of medication was obtained from SISMED and Farmaprecios. The costs of macro and microvascular events were based on POS tariffs, SOAT Manual and consultation with local expert. The discount rate on costs and benefits was 3.5%. Results: The group treated with saxagliptin had fewer fatal and nonfatal events and fewer episodes of hypoglycemia than the one with sulfonylureas. In both strategies the higher cost corresponds to the drugs, followed by those associated with the treatment of myocardial infarction. The incremental cost of saxagliptin therapy was US$ 555.552 to 20 years. Saxagliptin treatment resulted in a greater number of quality-adjusted life year (QALYs and life-years gained (LYG than that obtained with sulfonylureas. The cost per QALY was US$ 2,190. Cost-effectiveness results were robust to sensitivity analysis. Conclusion: Addition of saxagliptin to patients who do not achieve adequate glycemic control with metformin, is highly cost-effective compared with the addition of sulphonylureas.

    Full Text Available In this study we compare the cost-effectiveness of saxagliptin (Onglyza® in combination with metformin to that of either sulphonylurea (SU plus metformin or a thiazolidinedione  (TZD plus metformin, in type 2 diabetes mellitus patients who are not well-controlled on metformin alone. By using decision-analytic modeling, long-term costs and health outcomes associated with the investigated treatment strategies are estimated. This is achieved by modeling the risk of experiencing diabetes-related events (e.g. myocardial infarction or side-effects such as hypoglycemia and weight gain. The risk of these events  depends on baseline characteristics as well as risk factors (which can be altered by the treatment strategies. Ultimately, costs (NHS perspective and quality-adjusted life years (QALYs for each treatment strategy are based on the occurrence of these events. Based on these estimates incremental cost-effectiveness ratios (cost per QALYs are calculated. In the analysis comparing saxagliptin + metformin with SU + metformin in 1,000 patients in a 40 years time horizon, the total QALY gain with saxagliptin + metformin is 111. The incremental cost with saxagliptin + metformin is € 1,300,000, resulting in a total cost per QALY gained with saxagliptin + metformin of € 11,800 in the base case scenario. Similarly, the comparison with TZD + metformin resulted in a total  QALY gain with saxagliptin + metformin of 127, with an incremental cost of € 144,000, resulting in a total cost per QALY gained with saxagliptin + metformin of € 1,100 in the base case scenario. The results are mainly driven by differences in hypoglycemias (associated with a utility decrement and a monetary cost and weight gain (which is associated with a utility decrement and also increases the risk for diabetes-related events. Saxagliptin + metformin is associated with small difference in macrovascular events such as myocardial infarction, congestive heart failure compared to

Because of the progressive pathophysiology of T2DM, oral antidiabetic agents often fail to provide sustained glycemic control, indicating the need for new therapies. Saxagliptin (Onglyza™; Bristol-Myers Squibb Company, Princeton, NJ, USA; AstraZeneca Pharmaceuticals LP, Wilmington, DE, USA is an oral dipeptidyl peptidase-4 inhibitor, recently approved for the treatment of T2DM.Evidence review: Saxagliptin significantly improves glycemic control vs placebo, as demonstrated by decreasing glycated hemoglobin, fasting plasma glucose, and postprandial plasma glucose levels when used as monotherapy; in initial combination with metformin; and as add-on therapy with metformin, sulfonylurea (SU, or thiazolidinedione (TZD. Saxagliptin also significantly improves β-cell function, is weight neutral, has a low risk for hypoglycemia, and has been shown to have cardiovascular safety.Place in therapy: The clinical profile for saxagliptin indicates that it is useful as an adjunct to diet and exercise as first-line monotherapy and in combination with metformin; or as add-on treatment for patients who cannot achieve glycemic control with a combination of diet and lifestyle changes and metformin, SU, or TZD.Keywords: dipeptidyl peptidase-4 (DPP-4 inhibitor, GLP-1, HbA1c, incretin, saxagliptin

Saxagliptin (SAXA/metformin (MET FDC tablets can be used either alone or in combination with glyburide, thiazolidinediones, or insulin. It has been proven that the SAXA/MET combination leads to a significant improvement in glycemic control compared to placebo in patients with type 2 diabetes that is inadequately controlled with MET alone. In addition, this FDC has been proven to be safe for people with diabetes mellitus and established cardiovascular disease, elderly patients, and patients with impaired renal function (>30 mL/minute, with dosage modification. Patient compliance, adherence, and persistence to the therapeutic regimen has been shown to be very good, while the titration of each compound according to the patient's profile is easy, given the availability of different formulations. The SAXA/MET FDC is a patient-friendly, dosage-flexible, and hypoglycemia-safe regimen with very few adverse events and a neutral or even favorable effect on body weight. It achieves significant glycosylated hemoglobin A1c reduction helping the patient to achieve his/her individual glycemic goals.

    The increasing prevalence of diabetes and its inadequate management results in a heavy burden of the disease for the patients, the health and the productive system and the overall community. Consequently, it is necessary to have new effective drugs to treat people with diabetes to decrease such burden. DPP-4 inhibitors can help to cope with this demand, but its usage is challenged by its apparent high cost. The aim of the current study was to compare a simulated cost-effectiveness ratio of metformin (MET) plus one drug of the DPP-4 inhibitors family, saxagliptin (SAXA) or sulfonylurea (SU) treatment during a 20-year period, from the perspective of the social security system, in a cohort of people with Type 2 diabetes (T2DM) who did not attain glycosylated hemoglobin treatment target values only with MET. A discrete event simulation model (Cardiff diabetes model) based on UKPDS 68 was used to simulate disease progression and to estimate the economic and health treatment consequences in people with T2DM. The clinical efficacy parameters for SAXA administration were obtained from the literature; local standard costs were considered for drug acquisition, adverse events (AEs), and micro/macrovascular complications. Costs were expressed in US dollars (2009) with an annual 3.5% discount and a 20-year time horizon. The SAXA + MET treated group had a lower number of non-fatal events than the SU + MET treated group. The model also predicted a lower number of fatal macrovascular events for the SAXA + MET group (149.6 vs. 152.8). The total cost of the SAXA + MET cohort was 15% higher than that of the SU + MET cohort. Treatment with SAXA + MET resulted in a higher number of quality-adjusted life years (QALYs) (9.54 vs. 9.32) and life-years gained (LYGs) (20.84 vs. 20.76) compared to those treated with SU + MET. The incremental cost per QALY and LYG gained was $7,374 and $20,490, respectively. According to the criteria proposed by the Commission on Macroeconomics and Health, the

    To examine whether concomitant statin therapy affects glycemic control with saxagliptin 2.5 and 5mg/d in patients with type 2 diabetes mellitus (T2DM). Efficacy and safety were analyzed post hoc for pooled data from 9 saxagliptin randomized, placebo-controlled trials with a primary 24-week treatment period (4 monotherapy, 2 add-on to metformin, 1 each add-on to a sulfonylurea, thiazolidinedione, or insulin±metformin). Safety was also assessed in an 11-study, 24-week pool and an extended 20-study pool, which included 9 additional 4- to 52-week randomized studies. Comparisons were performed for patient groups defined by baseline statin use. Saxagliptin produced greater mean reductions in glycated hemoglobin than placebo, with no interaction between treatment and baseline statin use (P=0.47). In patients receiving saxagliptin 2.5 and 5mg and placebo, the proportion of patients with ≥1 adverse event (AE) was 78.1%, 64.0%, and 63.2%, respectively, in patients with any statin use and 70.6%, 57.9%, and 55.0% in patients with no statin use. Serious AEs, deaths, and symptomatic confirmed hypoglycemia (fingerstick glucose ≤50mg/dL) were few and similar, irrespective of baseline statin use. Saxagliptin improves glycemic control and is generally well tolerated in patients with T2DM, irrespective of concomitant statin therapy. Copyright © 2014 Elsevier Inc. All rights reserved.

Efficacy outcomes were the adjusted mean change from baseline in glycated hemoglobin (HbA1c) level, fasting plasma glucose concentration, and body weight and the proportion of patients achieving an HbA1c level history/no history of CVD, 2) ≥ 2 versus 0 to 1 CV risk factors, 3) hypertension/no hypertension, and 4) statin use/no statin use. Adverse events (AE) and hypoglycemia were monitored. In the initial combination therapy study, reductions in HbA1c level from baseline were greater with saxagliptin versus placebo in all subgroups (difference [saxagliptin - placebo], -0.38% to -0.67%). In the add-on to insulin ± metformin study, differences in adjusted mean change in HbA1c level versus placebo ranged from -0.23% to -0.58% across subgroups. In the noninferiority to glipizide study, adjusted mean changes in HbA1c level were comparable between saxagliptin and glipizide, across subgroups (difference, 0.08%-0.21%). No evidence suggested clinically relevant treatment-by-subgroup interactions in pairwise comparison. Incidences of ≥ 1 AE were comparable across subgroups. Incidences of confirmed hypoglycemia with saxagliptin were 0 in both metformin add-on studies and 1.2% to 7.8% with saxagliptin + insulin ± metformin. In patients with T2DM, saxagliptin 5 mg/d was similarly effective in improving glycemic control, with an AE profile similar to that of placebo, irrespective of CVD history, number of CV

    Saxagliptin is a potent, reversible inhibitor of dipeptidyl peptidase-4 that is indicated for the treatment of type 2 diabetes. The DIAPAZON study was a multicenter observational study intended to document the effectiveness, safety and patterns of saxagliptin use in France, including the saxagliptin retention rate, over 2 years of follow-up. A geographically representative sample of 304 French physicians (general practitioners and specialist endocrinologists or diabetologists) recruited 1131 adults with type 2 diabetes into an ambispective cohort; 1033 fulfilled the inclusion criteria. All had started saxagliptin during the previous 6 months or at study inclusion, and follow-up was for 24 ± 3 months after starting saxagliptin. The mean age of the study population when starting saxagliptin was 61 years, and the mean HbA1c level was 8.0%; 79% had an HbA1c level ≥7%. Prior to starting saxagliptin treatment, most participants (91%) were receiving treatment with oral glucose-lowering drugs alone. The most commonly prescribed regimen at starting saxagliptin (53% of participants) was a combination of saxagliptin and metformin. The overall saxagliptin retention rate at 2 years was 79%, as estimated by the Kaplan-Meier method. The most common reasons for discontinuation were inadequate glycemic control (52%) and intolerance (22%). During the course of the study, the mean HbA1c level decreased to 7.0%, and the percentage of people with HbA1c change in body weight was -1.8 kg. A total of 294 hypoglycemic episodes were reported in 70 participants (6.8%) during the follow-up period. Of these, 143 episodes in 41 participants (4.0%) occurred when saxagliptin was used in combination with agents associated with hypoglycemia, such as insulin, sulfonylureas or glinides. Saxagliptin is efficacious and well tolerated in a real-world practice setting, with almost 80% of participants remaining on treatment after 2 years. AstraZeneca, France.

    Saxagliptin is a potent and selective inhibitor of the enzyme dipeptidyl peptidase 4. It is effective in the treatment of type 2 diabetes mellitus because it stimulates the pancreas to produce insulin. In the present study, a liquid chromatography method was developed and validated to quantify the drug in tablets. This method was based on the isocratic elution of saxagliptin, using a mobile phase consisting of 0.1% phosphoric acid at pH 3.0 - methanol (70: 30, v/v) at a flow rate of 1 mL.min-...

    Full Text Available Saxagliptin is a potent and selective inhibitor of the enzyme dipeptidyl peptidase 4. It is effective in the treatment of type 2 diabetes mellitus because it stimulates the pancreas to produce insulin. In the present study, a liquid chromatography method was developed and validated to quantify the drug in tablets. This method was based on the isocratic elution of saxagliptin, using a mobile phase consisting of 0.1% phosphoric acid at pH 3.0 - methanol (70: 30, v/v at a flow rate of 1 mL.min-1 with UV detection at 225 nm. The chromatographic separation was achieved in 8 minutes on a Waters XBridge C18 column (250 mm x 4.6 mm, 5µm maintained at ambient temperature. The proposed method proved to be specific and robust for the quality control of saxagliptin in pharmaceutical dosage forms, showing good linearity in the range of 15.0 - 100.0 µg.mL-1 (r>0.999, precision (RSD

    Simple, selective and reproducible spectrofluorimetric and spectrophotometric methods have been developed for the determination of vildagliptin and saxagliptin in bulk and their pharmaceutical dosage forms. The first proposed spectrofluorimetric method is based on the dansylation reaction of the amino group of vildagliptin with dansyl chloride to form a highly fluorescent product. The formed product was measured spectrofluorimetrically at 455 nm after excitation at 345 nm. Beer's law was obeyed in a concentration range of 100-600 μg ml-1. The second proposed spectrophotometric method is based on the charge transfer complex of saxagliptin with tetrachloro-1,4-benzoquinone (p-chloranil). The formed charge transfer complex was measured spectrophotometrically at 530 nm. Beer's law was obeyed in a concentration range of 100-850 μg ml-1. The third proposed spectrophotometric method is based on the condensation reaction of the primary amino group of saxagliptin with formaldehyde and acetyl acetone to form a yellow colored product known as Hantzsch reaction, measured at 342.5 nm. Beer's law was obeyed in a concentration range of 50-300 μg ml-1. All the variables were studied to optimize the reactions' conditions using factorial design. The developed methods were validated and proved to be specific and accurate for quality control of vildagliptin and saxagliptin in their pharmaceutical dosage forms.

    Full Text Available Background. This study was to explore the pharmacokinetics of saxagliptin (Sax in Goto–Kakizaki (GK rats complicated with depression induced by chronic unpredicted mild stress (CUMS. The comorbidity of diabetic patients with depression is becoming more and more epidemic. Whether depression mental disorder alters the pharmacokinetics of hypoglycemic drugs in diabetes patients is not clear.Methods. Five-week-old male GK rats were kept in the cage for 7 weeks in a specific pathogen free (SPF-grade lab until the emergence of diabetes and were then divided into two groups: control group and depression model group. Rats in the CUMS-induced depression group were exposed to a series of stressors for 8 weeks. Plasma serotonin and dopamine levels and behavior of open-field test were used to confirm the establishment of the depression model. All rats were given 0.5 mg/kg Sax orally after 8 weeks and blood samples were collected at different time points. The Sax concentration was assayed by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS. The CYP450 activity of the liver microsomes was determined by using cocktails of probe drugs in which the activities of CYP enzymes were assessed through the determination of the production of the probe drugs.Results. Statistically significant differences in Sax pharmacokinetics were observed for area under curve, clearance, peak concentration, peak time and mean residence time between the depression rats and the control rats, while no statistical differences were observed for half-time and distribution volume by HPLC-MS/MS analysis. The CYP450 activity had different changes in the depression group.Conclusions. These results indicated that CUMS-induced depression alters the drug metabolic process of Sax and CYP450 activity of the liver microsomal enzymes in GK rats.

    As a consequence of the EU Water Framework Directive more focus is now on discharges of hazardous substances from wastewater treatment plants and sewers. Thus, many municipalities in Denmark may have to adopt to future advanced treatment technologies. This paper describes a holistic assessment, which includes technical, economical and environmental aspects. The technical and economical assessment is performed on 5 advanced treatment technologies: sand filtration, ozone treatment, UV exclusively for disinfection of pathogenic microorganisms, membrane bioreactor (MBR) and UV in combination with advanced oxidation. The technical assessment is based on 12 hazardous substances comprising heavy metals, organic pollutants, endocrine disruptors as well as pathogenic microorganisms. The environmental assessment is performed by life cycle assessment (LCA) comprising 9 of the specific hazardous substances and three advanced treatment methods; sand filtration, ozone treatment and MBR. The technical and economic assessment showed that UV solely for disinfection purposes or ozone treatment is the most advantageous advanced treatment methods if the demands are restricted to pathogenic microorganisms. In terms of sustainability, sand filtration is the most advantageous method based on the technical and environmental assessment due to the low energy consumption and high efficiency with regards to removal of heavy metals.

    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.

    Janine de Zeeuw

    Full Text Available Buruli ulcer (BU is described as a relatively painless condition; however clinical observations reveal that patients do experience pain during their treatment. Knowledge on current pain assessment and treatment in BU is necessary to develop and implement a future guideline on pain management in BU.A mixed methods approach was used, consisting of information retrieved from medical records on prescribed pain medication from Ghana and Benin, and semi-structured interviews with health care personnel (HCP from Ghana on pain perceptions, assessment and treatment. Medical records (n = 149 of patients treated between 2008 and 2012 were collected between November 2012 and August 2013. Interviews (n = 11 were audio-taped, transcribed verbatim and qualitatively analyzed.In 113 (84% of the 135 included records, pain medication, mostly simple analgesics, was prescribed. In 48% of the prescriptions, an indication was not documented. HCP reported that advanced BU could be painful, especially after wound care and after a skin graft. They reported not be trained in the assessment of mild pain. Pain recognition was perceived as difficult, as patients were said to suppress or to exaggerate pain, and to have different expectations regarding acceptable pain levels. HCP reported a fear of side effects of pain medication, shortage and irregularities in the supply of pain medication, and time constraints among medical doctors for pain management.Professionals perceived BU disease as potentially painful, and predominantly focused on severe pain. Our study suggests that pain in BU deserves attention and should be integrated in current treatment.

    Antibiotic treatment of tuberculosis has a duration of several months. There is significant variability of the host immune response and the pharmacokinetic-pharmacodynamic properties of Mycobacterium tuberculosis sub-populations at the site of disease. A limitation of sputum-based measures of treatment response may be sub-optimal detection and monitoring of Mycobacterium tuberculosis sub-populations. Potential biomarkers and surrogate endpoints should be benchmarked against hard clinical outcomes (failure/relapse/death) and may need tailoring to specific patient populations. Here, we assess the evidence supporting currently utilized and future potential host and pathogen-based models and biomarkers for monitoring treatment response in active and latent tuberculosis. Biomarkers for monitoring treatment response in extrapulmonary, pediatric and drug resistant tuberculosis are research priorities.

    Background Buruli ulcer (BU) is described as a relatively painless condition; however clinical observations reveal that patients do experience pain during their treatment. Knowledge on current pain assessment and treatment in BU is necessary to develop and implement a future guideline on pain management in BU. Methodology A mixed methods approach was used, consisting of information retrieved from medical records on prescribed pain medication from Ghana and Benin, and semi-structured interviews with health care personnel (HCP) from Ghana on pain perceptions, assessment and treatment. Medical records (n = 149) of patients treated between 2008 and 2012 were collected between November 2012 and August 2013. Interviews (n = 11) were audio-taped, transcribed verbatim and qualitatively analyzed. Principal Findings In 113 (84%) of the 135 included records, pain medication, mostly simple analgesics, was prescribed. In 48% of the prescriptions, an indication was not documented. HCP reported that advanced BU could be painful, especially after wound care and after a skin graft. They reported not be trained in the assessment of mild pain. Pain recognition was perceived as difficult, as patients were said to suppress or to exaggerate pain, and to have different expectations regarding acceptable pain levels. HCP reported a fear of side effects of pain medication, shortage and irregularities in the supply of pain medication, and time constraints among medical doctors for pain management. Conclusions Professionals perceived BU disease as potentially painful, and predominantly focused on severe pain. Our study suggests that pain in BU deserves attention and should be integrated in current treatment. PMID:26402069

    With a prevalence of 40%, depression is the most frequent psychiatric diagnosis in Parkinson's disease. Quality of life in Parkinson's patients is severely restricted. There is still no clear evidence concerning the link between these disorders - findings exist that indicate common neurodegenerative processes. At the same time depression seems to develop as a dysfunctional coping reaction to the motoric, emotional, and social restrictions of Parkinson's disease. The authors point out particular features of the depressive symptom profile in patients with Parkinson's disease and recommend a step-by-step approach to assessing depression: screening, assessment by means of the ICD-10 criteria, quantitative evaluation of depressivity, and assessment of suicidality. A survey of current treatment options is provided: pharmacological, somatic, and psychological approaches are introduced and evaluated with respect to effectiveness in this special group of patients.

    2015-04-01

    Life cycle assessment was conducted to estimate the environmental impact of electronic waste (e-waste) treatment. E-waste recycling with an end-life disposal scenario is environmentally beneficial because of the low environmental burden generated from human toxicity, terrestrial ecotoxicity, freshwater ecotoxicity, and marine ecotoxicity categories. Landfill and incineration technologies have a lower and higher environmental burden than the e-waste recycling with an end-life disposal scenario, respectively. The key factors in reducing the overall environmental impact of e-waste recycling are optimizing energy consumption efficiency, reducing wastewater and solid waste effluent, increasing proper e-waste treatment amount, avoiding e-waste disposal to landfill and incineration sites, and clearly defining the duties of all stakeholders (e.g., manufacturers, retailers, recycling companies, and consumers).

    Full Text Available Throughout this article we aim to defend the presence of psychopathic traits in child and adolescent population. In psychology there are two fundamental theoretical contributions to the understanding of this disorder in childhood. One focuses on the aspects of antisocial behaviour (Lynam, 1997; and the other highlights the presence of a fundamental characteristic in identifying the disorder, known as the callous unemotional trait (CU, Frick, O'Brien, Wootton & McBurnett, 1994. We also present some of the instruments that are most used in the assessment of child and adolescent psychopathy, as well as some results in the treatment of this disease.

    Dejonckere, P H

    2000-01-01

    The proposal of this guideline or basic protocol is an attempt to reach better agreement and uniformity concerning the methodology for functional assessment of pathological voices. The purpose is to allow relevant comparisons with the literature when presenting/publishing the results of voice treatment, e.g. a phonosurgical technique, or a new/improved instrument or procedure for investigating the pathological voice. Meta-analyses of results of voice treatments are generally limited--and even impossible--due to the major diversity in assessing functional outcomes. A minimal, multidimensional set of basic measurements is proposed, suitable for all "common" dysphonias: it includes 5 different approaches: perception (grade, roughness, breathiness), videostroboscopy (closure, regularity, mucosal wave and symmetry), acoustics (jitter, shimmer, Fo-range and softest intensity), aerodynamics (phonation quotient), and self rating by the patient. The protocol is elaborated on the base of an exhaustive review of the literature, the experience of the Committee members, and of plenary discussions within the European Laryngological Society. Instrumentation is kept to a minimum, but considered essential for professionals performing phonosurgery.

  14. Incest perpetrators. Their assessment and treatment.

    Cole, W

    1992-09-01

    The multitude of articles published in the last decade in the area of intrafamilial sexual abuse highlight the complexity of the issue--both its assessment and treatment. Although no unique profile of an incest perpetrator exists, a review of studies revealed problems in the areas of sexual satisfaction, psychological functioning, interpersonal relationships, and family of origin. As well, incest families have been reported to be dysfunctional, with power imbalances; control struggles; indirect, unclear communication; and inappropriate coalitions among family members. Based on these observations, a wide range of treatment interventions now exists, including offender-oriented cognitive/behavioral therapies and a family-focused multimodal systems approach. Although questions remain to be answered in regard to the effectiveness and process of treatment, efforts limited to the recognition of these problematic families are no longer adequate. The focus must move to prevention through the early identification of individuals at risk both for offending and being part of an incest family structure; the implementation of proven, cost-effective, proactive intervention strategies; and the continuing dissemination of information to the public.

    Women in treatment for substance abuse have been reported to have more severe problems at assessment than men but not to differ in treatment retention. To examine gender differences in problems at assessment, 30-day retention, and treatment completion, data from Detroit's publicly funded substance abuse treatment system were used. Women had significantly more severe problems at assessment, lower 30-day retention, and lower treatment completion rates than men. These gender differences in retention remained significant even after controlling for problem severity, primary drug of abuse, and referred treatment setting. There was no evidence of improvements in women's problems at assessment or retention over time during this period. Women presented with more severe problems at assessment and were less likely to stay in treatment for 30 days or to complete treatment than men. Monitoring gender differences in problems at presentation and retention outcomes is recommended to assess local need for interventions.

    The prevention and treatment of the periodontal diseases is based on accurate diagnosis, reduction or elimination of causative agents, risk management and correction of the harmful effects of disease. Prominent and confirmed risk factors or risk predictors for periodontitis in adults include smoking, diabetes, race, P. gingivalis, P. intermedia, low education, infrequent dental attendance and genetic influences. Several other specific periodontal bacteria, herpesviruses, increased age, male, sex, depression, race, traumatic occlusion and female osteoporosis in the presence of heavy dental calculus have been shown to be associated with loss of periodontal support and can be considered to be risk indicators of periodontitis. The presence of furcation involvement, tooth mobility, and a parafunctional habit without the use of a biteguard are associated with a poorer periodontal prognosis following periodontal therapy. An accurate diagnosis can only be made by a thorough evaluation of data that have been systematically collected by: 1) patient interview, 2) medical consultation as indicated, 3) clinical periodontal examination, 4) radiographic examination, and 5) laboratory tests as needed. Clinical signs of periodontal disease such as pocket depth, loss of clinical attachment and bone loss are cumulative measures of past disease. They do not provide the dentist with a current assessment of disease activity. In an attempt to improve the ability to predict future disease progression, several types of diagnostic tests have been studied, including host inflammatory products and mediators, enzymes, tissue breakdown products and subgingival temperature. In general, the usefulness of these tests for predicting future disease activity remains to be established in terms of sensitivity, specificity and predictive value. Although microbiological analysis of subgingival plaque is not necessary to diagnose and treat most patients with periodontitis, it is helpful when treating

    A new, simple, selective, reproducible and sensitive stability-indicating liquid chromatographic method was developed and subsequently validated for the determination of saxagliptin (SXG). SXG was subjected to oxidation, thermal, acid hydrolysis, alkali hydrolysis and photodegradation according to ICH guidelines. The major degradation products were separated from the pure drug and the proposed structures' elucidation was performed, using an LC-MS technique. Isocratic chromatographic elution was achieved on a Symmetry(®) C18 column (150 × 4.6 mm, 5 µm), using a mobile phase of potassium dihydrogen phosphate buffer (pH 4.6)-acetonitrile-methanol (40 : 30 : 30, v/v/v) at a flow rate of 1 mL min(-1) with UV detection at 208 nm. Linearity, accuracy and precision were found to be acceptable over the concentration range of 25-400 µg mL(-1). All the results were statistically compared with the reference method, using one-way analysis of variance. The developed method was validated and proved to be specific and accurate for quality control of SXG in pharmaceutical dosage form.

    Acute Achilles tendon rupture is a frequent and potentially disabling injury. Over the past decade a change in treatment of acute Achilles tendon rupture away from operative towards non-operative treatment has taken place. However, the optimal non-operative treatment protocol remains to be clarified, particularly the role of weight-bearing during early rehabilitation. Also, there is a need for a clinically applicable and accurate measurement to detect patients in risk of developing Achilles tendon elongation. The aim of this PhD thesis was to evaluate non-operative treatment of acute Achilles tendon rupture. In study I, a cross-sectional survey was performed investigating the chosen treatment protocols across Scandinavia. In study II, the effect of immediate weight-bearing on patient reported and functional outcomes was investigated in a randomized controlled trial (RCT). In study III, the effect of immediate weight-bearing on the biomechanical properties of the plantar flexor muscle-tendon complex was investigated in an RCT. In study IV, validity, reliability and agreement of a novel ultrasound measurement of Achilles tendon length and elongation was tested. Study I found surgery to be the preferred treatment in 83% of departments in Denmark, 92% in Norway, 65% in Sweden, and 30% in Finland (p tendon complex. Study IV showed excellent intra-rater reliability (ICC 0.96, SEM 3.7 mm and MDC 10.3 mm), inter-rater reliability (ICC 0.97, SEM 3.3 mm and MDC 9.3 mm) and validity (measurement error 2%). Treatment algorithms across Scandinavia showed considerable variation, though operative treatment and controlled early weight-bearing was the preferred treatment in Denmark, Norway and Sweden. Immediate weight-bearing was found to be safe and recommendable in non-operative treatment of acute Achilles tendon rupture. The novel ultrasound measurement showed excellent reliability and acceptable validity and agreement.

  6. Perinatal Generalized Anxiety Disorder: Assessment and Treatment.

    2015-09-01

    Perinatal generalized anxiety disorder (GAD) has a high prevalence of 8.5%-10.5% during pregnancy and 4.4%-10.8% postpartum. Despite its attendant dysfunction in the patient, this potentially debilitating mental health condition is often underdiagnosed. This overview will provide guidance for clinicians in making timely diagnosis and managing symptoms appropriately. A significant barrier to the diagnosis of GAD in the perinatal population is difficulty in distinguishing normal versus pathological worry. Because a perinatal-specific screening tool for GAD is nonexistent, early identification, diagnosis and treatment is often compromised. The resultant maternal dysfunction can potentially impact mother-infant bonding and influence neurodevelopmental outcomes in the children. Comorbid occurrence of GAD and major depressive disorder changes the illness course and its treatment outcome. Psychoeducation is a key component in overcoming denial/stigma and facilitating successful intervention. Treatment strategies are contingent upon illness severity. Cognitive behavior therapy (CBT), relaxation, and mindfulness therapy are indicated for mild GAD. Moderate/severe illness requires pharmacotherapy and CBT, individually or in combination. No psychotropic medications are approved by the FDA or Health Canada in pregnancy or the postpartum; off-label pharmacological treatment is instituted only if the benefit of therapy outweighs its risk. SSRIs/SNRIs are the first-line treatment for anxiety disorders due to data supporting their efficacy and overall favorable side effect profile. Benzodiazepines are an option for short-term treatment. While research on atypical antipsychotics is evolving, some can be considered for severe manifestations where the response to antidepressants or benzodiazepines has been insufficient. A case example will illustrate the onset, clinical course, and treatment strategies of GAD through pregnancy and the postpartum.

  9. Life Cycle Assessment of Horse Manure Treatment

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available Horse manure consists of feces, urine, and varying amounts of various bedding materials. The management of horse manure causes environmental problems when emissions occur during the decomposition of organic material, in addition to nutrients not being recycled. The interest in horse manure undergoing anaerobic digestion and thereby producing biogas has increased with an increasing interest in biogas as a renewable fuel. This study aims to highlight the environmental impact of different treatment options for horse manure from a system perspective. The treatment methods investigated are: (1 unmanaged composting; (2 managed composting; (3 large-scale incineration in a waste-fired combined heat and power (CHP plant; (4 drying and small-scale combustion; and (5 liquid anaerobic digestion with thermal pre-treatment. Following significant data uncertainty in the survey, the results are only indicative. No clear conclusions can be drawn regarding any preference in treatment methods, with the exception of their climate impact, for which anaerobic digestion is preferred. The overall conclusion is that more research is needed to ensure the quality of future surveys, thus an overall research effort from horse management to waste management.

    Specific phobia is one of the most common and easily treated mental disorders. In this review, empirically supported assessment and treatment procedures for specific phobia are discussed. Exposure-based treatments in particular are highlighted given their demonstrated effectiveness for this condition. The format and characteristics of exposure-based treatment and predictors of treatment response are outlined to provide recommendations for maximizing outcome. In addition, several other treatments for specific phobia are reviewed and critiqued, including cognitive therapy, virtual reality, eye movement desensitization and reprocessing, applied tension, and pharmacologic treatments. The review concludes with a discussion of future directions for research.

  13. Assessment and treatment of pain in thalassemia.

    Science.gov (United States)

    Lal, Ashutosh

    2016-03-01

    Pain is a subjective symptom whose prevalence can be grossly underestimated. The high proportion of adults with thalassemia who experience chronic pain is evident from recent surveys. However, pain has not received enough attention in the overall management of thalassemia. The association of pain with the type and treatment of thalassemia or with its comorbidities is unclear. Abnormal spine imaging is seen in patients reporting pain, although the role of osteopenia has not been established. Pain becomes more frequent with age. The lower back is the most common site and can be particularly disabling and difficult to treat. Treatable causes, such as extramedullary masses or disc herniation or fractures, must be ruled out. Some adults experience increasing pain when the hemoglobin drops at the end of transfusion cycles. Interdisciplinary management of pain is necessary, while overreliance on medications can be counterproductive. The impact of chronic pain on the quality of life must be acknowledged. Physical therapy, psychological counseling, and vocational rehabilitation are vital to management. I recommend a proactive approach for prevention of pain by maintaining optimal bone density and an active lifestyle. I further propose that a universal tool be adopted to document and characterize pain at routine clinic visits. © 2016 New York Academy of Sciences.

    Full Text Available Systematic outcome assessment is central to ascertaining the impact of treatment services and to informing future treatment initiatives. This project was designed to be conducted within the clinical operations of 4 private addictions treatment centers. A structured interview was used to assess patients’ alcohol and other drug use and related variables (on treatment entry and at 1, 3, and 6 months following treatment discharge. The primary outcomes were percentage of days abstinent (PDA from alcohol and drugs, PDA from alcohol, and PDA from other drugs. Collateral reports during follow-up also were gathered. A total of 280 patients (56% men across the 4 programs participated. Percentage of days abstinent for each outcome increased significantly from baseline to the 1-month follow-up assessment, and this change was maintained at the 3- and 6-month follow-up assessments. Collateral reports mirrored the patient follow-up reports. Secondary outcomes of patient ratings of urges/cravings, depression, anxiety, and general life functioning all indicated significant improvement from baseline over the course of the follow-up. The results suggest the feasibility of conducting systematic outcome assessment in freestanding private addictions treatment environments.

  19. Strategies for microwave thermal treatment planning, navigation, and assessment

    Ryan, Thomas P.

    2011-03-01

    Thermal treatment is commonly performed interstitially in either surgical or percutaneous procedures, using microwave antenna sources at 915 or 2540 MHz. There are a number of tools or aids as well as challenges for clinicians performing these procedures in the course of patient treatment. These challenges will be present whether the procedure is surgical, laparoscopic, or percutaneous, and include treatment planning, image guidance, navigation, coregistration in 3D, and treatment assessment. Treatment planning has been used historically in hyperthermia for microwave antenna arrays, but has yet to be properly applied in thermal ablation. Image assessment of thermal treatment is not typically performed in real time, although these tools will provide the clinician with further information to understand the extent of treatment and whether further treatment is needed. 3D imaging is available, but not coregistered to patient space. Navigation has been used in many medical specialties, but is also not in the clinician's toolbox in thermal treatment. Although treatment planning will lay out the skin entry and trajectory for each antenna placed, subsequently, each antenna needs to be tracked to accurately show placement in the patient and overlaid in patient space, along with the tumor target location. Some patient treatments may consist of multiple, but sequential single placements of an antenna, and guidance is even more critical to track positions and plan for the next insertion. Lastly, real-time image assessment will show the extent and shape of the coagulated lesion and which targets may have been undertreated. If used synchronously in arrays, MW power steering may also aid in filling in the ablation as the treatment progresses. This paper will analyze the present state-of-the art as well as a strategy to incorporate the various facets of planning, guidance, and assessment of treatment.

    1993-03-01

    Groundwater recovery and treatment (pump and treat systems) continue to be the most commonly selected remedial technology for groundwater restoration and protection programs at hazardous waste sites and RCRA facilities nationwide. Implementing a typical groundwater recovery and treatment system includes the initial assessment of groundwater quality, characterizing aquifer hydrodynamics, recovery system design, system installation, testing, permitting, and operation and maintenance. This paper focuses on methods used to assess the long-term efficiency of a pump and treat system. Regulatory agencies and industry alike are sensitive to the need for accurate assessment of the performance and success of groundwater recovery systems for contaminant plume abatement and aquifer restoration. Several assessment methods are available to measure the long-term performance of a groundwater recovery system. This paper presents six assessment techniques: degree of compliance with regulatory agency agreement (Consent Order of Record of Decision), hydraulic demonstration of system performance, contaminant mass recovery calculation, system design and performance comparison, statistical evaluation of groundwater quality and preferably, integration of the assessment methods. Applying specific recovery system assessment methods depends upon the type, amount, and quality of data available. Use of an integrated approach is encouraged to evaluate the success of a groundwater recovery and treatment system. The methods presented in this paper are for engineers and corporate management to use when discussing the effectiveness of groundwater remediation systems with their environmental consultant. In addition, an independent (third party) system evaluation is recommended to be sure that a recovery system operates efficiently and with minimum expense.

  1. Reporting methods of blinding in randomized trials assessing nonpharmacological treatments.

    2007-02-01

    Full Text Available BACKGROUND: Blinding is a cornerstone of treatment evaluation. Blinding is more difficult to obtain in trials assessing nonpharmacological treatment and frequently relies on "creative" (nonstandard methods. The purpose of this study was to systematically describe the strategies used to obtain blinding in a sample of randomized controlled trials of nonpharmacological treatment. METHODS AND FINDINGS: We systematically searched in Medline and the Cochrane Methodology Register for randomized controlled trials (RCTs assessing nonpharmacological treatment with blinding, published during 2004 in high-impact-factor journals. Data were extracted using a standardized extraction form. We identified 145 articles, with the method of blinding described in 123 of the reports. Methods of blinding of participants and/or health care providers and/or other caregivers concerned mainly use of sham procedures such as simulation of surgical procedures, similar attention-control interventions, or a placebo with a different mode of administration for rehabilitation or psychotherapy. Trials assessing devices reported various placebo interventions such as use of sham prosthesis, identical apparatus (e.g., identical but inactivated machine or use of activated machine with a barrier to block the treatment, or simulation of using a device. Blinding participants to the study hypothesis was also an important method of blinding. The methods reported for blinding outcome assessors relied mainly on centralized assessment of paraclinical examinations, clinical examinations (i.e., use of video, audiotape, photography, or adjudications of clinical events. CONCLUSIONS: This study classifies blinding methods and provides a detailed description of methods that could overcome some barriers of blinding in clinical trials assessing nonpharmacological treatment, and provides information for readers assessing the quality of results of such trials.

  2. A Review on Assessment and Treatment for Depression in Malaysia

    2011-01-01

    Full Text Available This paper aimed to review the literature on depression that focused on its assessment and treatment in Malaysia. PsycINFO, Medline, local journals were searched, and 18 published articles were included in this paper. Results indicate that research on depression in Malaysia, particularly validation studies and psychotherapy research, was weak and fragmented, with minimal empirical evidence available. Pharmacotherapy still dominated the treatment for depression, and, in terms of psychotherapy, Cognitive Behavioural Therapy (CBT was recently practiced, but only a few studies have reported on the treatment efficacy of CBT. Major limitations of studies were noted, and, consequently, the problems that are associated with the implementation and future direction of clinical and research on depression in Malaysia were discussed. In short, the contribution of empirical research on the assessment and treatment for depression remained inconsistent and fragmented and urgently in need of further empirical investigation.

    2012-02-01

    In the present article, the efficiency of biological treatment of landfill leachates was evaluated by implementation of physicochemical characterisation and a complex toxicity assessment. An array of toxicity tests using bacterium Vibrio fischeri, alga Desmodesmus subspicatus, crustacean Daphnia magna, and embryo of fish Danio rerio, as well as unconventional methods using biochemical biomarkers (protein content, enzymes cholinesterase, and glutathione-S-transferase), were employed. Toxicity of leachates varied depending on the season of collection in relation to their different physicochemical characteristics. Uncommon effects of leachates on organisms, such as hormetic-like increases of algal growth and reproduction of daphnids, were identified. New approaches using the activities of enzymes were found unsuitable for routine hazard assessment of leachates. Although physicochemical parameters and toxicity decreased significantly after biological treatment, the effluents did not meet the demands of the current Slovenian legislation; thus, the existing biological treatment was found inappropriate. The development of advanced treatment techniques for landfill leachates is thus encouraged.

    2015-01-01

    Recent developments in magnetic resonance(MR) functional quantitative imaging have made it a potentially powerful tool to assess treatment response in radiation therapy. With its abilities to capture functional information on underlying tissue characteristics, MR functional quantitative imaging can be valuable in assessing treatment response and as such to optimize therapeutic outcome. Various MR quantitative imaging techniques, including diffusion weighted imaging, diffusion tensor imaging, MR spectroscopy and dynamic contrastenhanced imaging, have been investigated and found useful for assessment of radiotherapy. However, various aspects including data reproducibility, interpretation of biomarkers, image quality and data analysis impose challenges on applications of MR functional quantitative imaging in radiotherapy assessment. All of these challenging issues shall be addressed to help us understand whether MR functional quantitative imaging is truly beneficial and contributes to future development of radiotherapy. It is evident that individualized therapy is the future direction of patient care. MR functional quantitative imaging might serves as an indispensable tool towards this promising direction.

    Sewage treatment, treated water treatment and sludge treatment are three basic units of an integrated sewage treatment system. This work assessed the influence of reusing or discharge of treated water and sludge landfill or compost on the sustainability of an integrated sewage treatment system using emergy analysis and newly proposed emergy indicators. This system's value included its environmental benefits and the products. Environmental benefits were the differences of the environmental service values before and after sewage treatment. Due to unavailability of data of the exchanged substance and energy in the internal system, products' values were attained by newly proposed substitution values. The results showed that the combination of sewage treatment, treated water reuse and sludge landfill had the strongest competitiveness, while the combination of sewage treatment, treated water reuse and earthworm compost was the most sustainable. Moreover, treated water reuse and earthworm compost were helpful for improving the sustainability of the integrated sewage treatment system. The quality of treated water and local conditions should be also considered when implementing the treated water reuse or discharge. The resources efficiency of earthworm compost unit needed to be further improved. Improved emergy indices were more suitable for integrated sewage treatment systems.

    Clinical assessment of a child with Tourette's syndrome (TS) includes a careful review of motor and phonic tics. In addition, commonly associated problems of such as obsessive-compulsive symptoms, or symptoms of attention deficit hyperactivity disorder (inattention, impulsiveness, and overactivity) should also be evaluated. Treatment almost always includes education of the child, family, and school personnel concerning the natural history and behavioral boundaries of the disorder. Other treatment interventions depend to a great extent on the primary source of impairment. This article, the second of two parts, presents three illustrative cases and reviews current treatment interventions for children and adolescents with TS.

    2012-07-01

    Although legal, formal, and informal social controls are frequently used to pressure individuals to enter treatment, motivational consequences of using these tactics have been neglected. Self-determination theory (SDT) provides a useful perspective for understanding client experiences of social controls and highlights the importance of self-determined motivation for long-term behavior change. This study assessed the construct validity of the Treatment Entry Questionnaire (TEQ), a brief scale derived from SDT to measure identified, introjected, and external treatment motivation. Two independent samples of clients entering Canadian residential and outpatient treatment completed TEQ items (ns = 529 and 623). Exploratory and confirmatory factor analyses supported a 9-item version of the scale, with 3 factors aligning with SDT motivational subtypes. Subscales showed high internal consistency and correlated as expected with social controls and perceived coercion at treatment entry. The TEQ-9 is a valid option for assessing self-determined motivation in clinical practice and evaluating coerced addiction treatment.

    Sleep disorders in children can compromise quality of life of both children and families and chronic sleep deprivations is associated with poorer developmental outcome, overweight and behavioral disturbances. Clinicians should incorporate questions about sleep into their routine health assessment, and the assessment of insomnia should follow a medical approach primary and secondary contributing factors should be assessed, as well as maladaptive behaviors related to sleep. A careful examination of sleep/wake schedule, abnormal movements or behavior during sleep, and daytime consequences of sleep disruption or deprivation is mandatory. Sleeping environment, and bedtime routines should be examined to identify behavioral issues related to sleep. Polysomnography is not routinely indicated for children with insomnia, but actigraphy can give an objective estimation of sleep parameters. The Authors propose a new classification of pediatric insomnia, based on both genetic and clinical aspects, and suggest specific treatment options, including sleep hygiene, behavioral strategies and pharmacological treatment.

    Full Text Available Spinal cord injury (SCI is a devastating disease which may cause physical, psychological and social dysfunction. Neuropathic pain (NP after SCI is common, can be seen in varying degrees and is one of the most difficultly treated problems developing after SCI. With the addition of the NP to loss of function after SCI, sleep patterns, moods and daily activities of patients are adversely affected. In order to treat pain effectively, classification of pain after SCI must be done carefully and correctly. According to classification of International Pain Study Group, pain after SCI is divided into two main groups as nociceptive and neuropathic pain. Neuropathic pain is defined as %u201Cpain occuring as a direct result of a disease or lesion directly affecting somato-sensorial system%u201D. NP after SCI can be classified according to anatomical region (above the level of lesion, at the level of lesion, below the level of lesion. Treatment of NP after SCI is often challenging and receiving response to treatment may take long time. Therefore, treatment of NP after SCI should be multifactorial. Treatment options include pharmochologic treatment, application of transcutanous electrical nerve stimulation, psychiatric treatment approaches, and surgical approaches in selected cases. In pharmachologic treatment, first line agents are tricyclic antidepresants, pregabalin and gabapentin. In this review, mechanisms and assessment and treatment of NP after SCI is discussed with the guide of current literature.

    2010-09-01

    The main function of a Wastewater Treatment Plant is to minimize the environmental impact of discharging untreated water into natural water systems. Also a Wastewater Treatment Plant may get a resource from wastewater carrying out a tertiary treatment on the treated wastewater which can be reused in non-potable applications. Water reuse strategies are intended to address the problem of water scarcity without aggravating other environmental problems, thus reflecting the need of their environmental assessment. In this paper we used Life Cycle Assessment to evaluate different disinfection treatments (chlorination plus ultraviolet treatment, ozonation and ozonation plus hydrogen peroxide) and to assess the environmental advantages and drawbacks of urban wastewater reuse in non-potable applications. To do so, we compared the environmental impacts of producing 1m(3) of water for non-potable uses from reclaimed water, potable water and desalinated water sources. The calculation has used current operating data from a Wastewater Treatment Plant located in the Mediterranean area, although the results can be applied to any other plant with similar technology. The ozonation and ozonation plus hydrogen peroxide disinfection treatment technologies have similar environmental profiles. However most of the indicators are about 50% higher than the ultraviolet disinfection except for the acidification (100% higher) and photochemical oxidation (less than 5%). Non-potable uses (both agricultural and urban uses) of reclaimed water have environmental and economical advantages. Reuse of treated wastewater is particularly beneficial when it can replace desalinated water. Consequently, reclaimed water should be promoted for non-potable uses, when there is scarcity of freshwater.

      The Urban Wastewater Treatment Directive 91/271/EEC introduced a series of measures for the purpose of protecting the environment from the adverse effects of effluent discharge from wastewater treatment plants.  There are environmental costs associated with attaining the required level of water quality set out in the directive such as greenhouse gas emissions due to energy production, and ecotoxicity from sludge application to land.  The goal of this study is to assess the environmental costs in an Irish context, focusing specifically on the effects of variation in scale and discharge limitation. Life cycle assessment is the analytical tool used to evaluate the environmental impact.  The life cycle impact assessment methodology developed by the Centre of Environmental Science, Leiden University (2010 has been adopted and implemented using GaBi 6.0 life cycle assessment software.  Two plants of varying size and location were chosen for the study. The study found that energy consumption and sludge application to land are the largest contributors to the overall environmental impact associated with the treatment process at both plants.  Economies of scale were observed in energy usage during secondary aeration.

    Full Text Available This paper intends to assess the technological process of obtaining drinking water at Targu-Mures water treatment plant. The assessment was performed before changing the technological process and four months were chosen to be analized during 2008: January, April, July and October for its efficiency analysis on treatment steps. Mures River is the water source for the water treatment plant, being characterized by unsteady flow and quality parameters with possible important variability in a very short period of time. The treatment technological process is the classic one, represented by coagulation, sedimentation, filtration and disinfection, but also prechlorination was constantly applied as additional treatment during 2008. Results showed that for the measured parameters, raw water at the water treatment plant fits into class A3 for surface waters, framing dictated by the bacterial load. The treatment processes efficiency is based on the performance calculation for sedimentation, filtration, global and for disinfection, a better conformation degree of technological steps standing out in January in comparison to the other three analyzed months. A variable non-compliance of turbidity and residual chlorine levels in the disinfected water was observed constantly. Previous treatment steps managed to maintain a low level of oxidisability, chlorine consumption and residual chlorine levels being also low. 12% samples were found inconsistent with the national legislation in terms of bacteriological quality. Measures for the water treatment plant retechnologization are taken primarily for hyperchlorination elimination, which currently constitutes a discomfort factor (taste, smell, and a generating factor of chlorination by-products.

    In this study, we investigated through an Internet survey of 508 practicing marriage and family therapists which treatment decisions varied by gender of the client and background variables of therapists. The subjects responded to several typical Internet infidelity scenarios. We varied the gender of the person initiating the infidelity for half of one sample. We also asked the family therapy participants to respond to how they might assess and treat each presenting problem. They also evaluated problem severity, prognosis of the case, number of sessions necessary for treatment, and the extent to which a therapist would focus individually or relationally. Results indicate that there were differences in how therapists assessed and treated clients based on client gender, therapists' age, therapists' gender, how religious therapists reported they were, and the extent of therapists' personal experience with infidelity.

    Juvenile dermatomyositis (JDM) is a rare, potentially life-threatening systemic autoimmune disease primarily affecting muscle and skin. Recent advances in the recognition, standardised assessment and treatment of JDM have been greatly facilitated by large collaborative research networks. Through these networks, a number of immunogenetic risk factors have now been defined, as well as a number of potential pathways identified in the aetio-pathogenesis of JDM. Myositis-associated and myositis-sp...

    Feeding and eating disorders (FEDs) are serious mental health disorders that cause impairments in physical health, development, cognition and psychosocial function and can go undetected for months or years. They are characterised by disturbed eating behaviour associated with concerns about weight and shape or by disinterest in food, phobic avoidance or avoidance due to sensory aspects of food. Restrictive forms of FEDs lead to significant weight loss requiring intervention. Without specific knowledge of these conditions, they can evade detection, delaying time to diagnosis and treatment and potentially influencing outcome. This review article focuses on the key factors involved in the psychiatric assessment and treatment of four feeding or eating disorders (EDs): anorexia nervosa, avoidant-restrictive food intake disorder, bulimia nervosa and binge eating disorder. They have been chosen for discussion as they are most likely to be encountered in both a psychiatric and paediatric setting. It emphasises the importance of a family-focused, developmentally appropriate and multidisciplinary approach to care. It does not address aspects of medical assessment and treatment. Other feeding or EDs not included in this article are pica, rumination disorder, other specified feeding and eating disorder and unspecified feeding and eating disorder.

    Negative symptoms in schizophrenia may be classified as primary or secondary. Primary negative symptoms are thought to be intrinsic to schizophrenia, while secondary negative symptoms are caused by positive symptoms, depression, medication side-effects, social deprivation or substance abuse. Most of the research on secondary negative symptoms has aimed at ruling them out in order to isolate primary negative symptoms. However, secondary negative symptoms are common and can have a major impact on patient-relevant outcomes. Therefore, the assessment and treatment of secondary negative symptoms are clinically relevant. Furthermore, understanding the mechanisms underlying secondary negative symptoms can contribute to an integrated model of negative symptoms. In this review we provide an overview of concepts, evidence, assessment and treatment for the major causes of secondary negative symptoms. We also summarize neuroimaging research relevant to secondary negative symptoms. We emphasize the relevance of recent developments in psychopathological assessment of negative symptoms, such as the distinction between amotivation and diminished expression, which have only rarely been applied in research on secondary negative symptoms.

    Full Text Available The purpose of this article was to evaluate the environmental performance of a medium-sized company that provides services for surface treatment of aluminum. The treatment is known as anodizing. The research method was qualitative numerical modeling. The environmental performance of the company was organized into five constructs: atmosphere, wastewater, energy and natural resources, solid waste, and legislation and management. Nineteen indicators were chosen to explain the five constructs. Ten employees of the company prioritized the constructs and evaluated the situation of the indicators by means of a scale of assessment. By means of a mathematical model, the general performance of the environmental operation was calculated at 74.5% of the maximum possible. The indicators that most contributed to the performance not to reach 100% were consumption of electricity and water consumption. The construct of worse performance was natural and energy resources. These are the priorities for future environmental improvement actions that the company may promote.

    It is difficult to determine whether early tuberculosis treatment is effective in reducing the infectiousness of patients' sputum, because culture takes weeks and conventional acid-fast sputum microscopy and molecular tests cannot differentiate live from dead tuberculosis. To assess treatment response, sputum samples (n=124) from unselected patients (n=35) with sputum microscopy-positive tuberculosis were tested pretreatment and after 3, 6, and 9 days of empiric first-line therapy. Tuberculosis quantitative viability microscopy with fluorescein diacetate, quantitative culture, and acid-fast auramine microscopy were all performed in triplicate. Tuberculosis quantitative viability microscopy predicted quantitative culture results such that 76% of results agreed within ±1 logarithm (rS=0.85; Ptuberculosis, viability and quantitative culture results approximately halved (both 0.27 log reduction, Ptuberculosis and available data, by treatment day 9 there was a >10-fold reduction in viability in 100% (24/24) of cases and quantitative culture in 95% (19/20) of cases. Four other patients subsequently found to have MDR tuberculosis had no significant changes in viability (P=.4) or quantitative culture (P=.6) results during early treatment. The change in viability and quantitative culture results during early treatment differed significantly between patients with non-MDR tuberculosis and those with MDR tuberculosis (both Ptreatment, and this change was similar for non-MDR tuberculosis vs MDR tuberculosis (P=.6). Tuberculosis quantitative viability microscopy is a simple test that within 1 hour predicted quantitative culture results that became available weeks later, rapidly indicating whether patients were responding to tuberculosis therapy. © The Author 2014.

    1991-01-01

    Based on the Helkimo index we assessed the success of conservative and conservative-surgical forms of treatment for mandibular fractures in a total of 166 patients. The control group consisted of 50 probands. The Helkimo dysfunction index, which is based on various criteria, showed dysfunction in 81.9% of the patients with only slight functional impairment in 57.2% of these cases. 18.1% of the patients were clinically symptom-free. A comparison with the probands revealed no major differences in dysfunction between the two groups. Significant differences were observed only in the case of 2 isolated criteria (maximum mandibular protrusion, muscle pain). Severe dysfunction, however, was more common in the fracture patients. Based on the Helkimo occlusion index disorder were noted in 91.7% of the patients, while severe occlusion disorder were observed particularly in patients with combined mandibular body and condyle fractures (40.0%). In the control group a more favorable occlusion index was found to be due mainly to the greater number of present and/or occluding teeth. The Helkimo index, particularly the dysfunctionindex, is a very useful instrument for assessing the success of treatment measures in mandibular fracture cases. It should be more commonly used to improve the possibilites of objective comparisons between patients from different hospitals.

Overall incidence and prevalence of TBI are likely to increase in absolute terms in the future. Tackling the problem of treating TBI successfully will require improvements in the understanding of normal cerebral anatomy, physiology, and function throughout the lifespan, as well as the pathological and recuperative responses that result from trauma. New treatment approaches and combinations will need to be targeted to the heterogeneous needs of TBI populations. This article explores and evaluates the research evidence in areas that will likely lead to a reduction in TBI-related morbidity and improved outcomes. These include emerging assessment instruments and techniques in areas of structural/chemical and functional neuroimaging and neuropsychology, advances in the realms of cell-based therapies and genetics, promising cognitive rehabilitation techniques including cognitive remediation and the use of electronic technologies including assistive devices and virtual reality, and the emerging field of complementary and alternative medicine.Keywords: traumatic brain injury, assessments, treatments

  18. Environmental assessment of digestate treatment technologies using LCA methodology.

    The production of biogas from energy crops, organic waste and manure has augmented considerably the amounts of digestate available in Flanders. This has pushed authorities to steadily introduce legislative changes to promote its use as a fertilising agent. There is limited arable land in Flanders, which entails that digestate has to compete with animal manure to be spread. This forces many anaerobic digestion plants to further treat digestate in such a way that it can either be exported or the nitrogen be removed. Nevertheless, the environmental impact of these treatment options is still widely unknown, as well as the influence of these impacts on the sustainability of Flemish anaerobic digestion plants in comparison to other regions where spreading of raw digestate is allowed. Despite important economic aspects that must be considered, the use of Life Cycle Assessment (LCA) is suggested in this study to identify the environmental impacts of spreading digestate directly as compared to four different treatment technologies. Results suggest relevant environmental gains when the digestate mix is treated using the examined conversion technologies prior to spreading, although important trade-offs between impact categories were observed and discussed. The promising results of digestate conversion technologies suggest that further LCA analyses should be performed to delve into, for instance, the appropriateness to shift to nutrient recovery technologies rather than digestate conversion treatments.

    Wastewater treatment plants (WWTPs) play an extremely important role in shaping modern society's environmental well-being and awareness, however only well operated and supervised systems can be considered as environmentally sustainable. For this reason, an attempt was undertaken to assess the environmental burden posed by WWTPs in major Polish cities by collecting water samples prior to and just after wastewater release points. Both classical and biological methods (Microtox(®), Ostracodtoxkit F™ and comet assay) were utilized to assess environmental impact of given WWTP. Interestingly, in some cases, water quality improvement indicated as a toxicity decrement toward one of the bio-indicating organisms makes water worse for others in the systems. This fact is particularly noticeable in case of Silesian cities where heavy industry and high population density is present. It proves that WWTP should undergo individual evaluation of pollutant removal efficiency and tuned to selectively remove pollutants of highest risk to surrounding regional ecosystems. Biotests again proved to be an extremely important tool to fully assess the impact of environmental stressors on water bodies receiving effluents from WWTPs.

    Full Text Available Seasonal affective disorder or SAD is a recurrent major depressive disorder with a seasonal pattern usually beginning in fall and continuing into winter months. A subsyndromal type of SAD, or S-SAD, is commonly known as “winter blues.” Less often, SAD causes depression in the spring or early summer. Symptoms center on sad mood and low energy. Those most at risk are female, are younger, live far from the equator, and have family histories of depression, bipolar disorder, or SAD. Screening instruments include the Seasonal Pattern Assessment Questionnaire (SPAQ. Typical treatment includes antidepressant medications, light therapy, Vitamin D, and counselling. This paper provides an overview of SAD.

    When we first meet the individual who has just had a stroke and their family members, we have an opportunity to set the stage for the individual's long-term adjustment to the effects of their cerebrovascular event. Or we can squander that opportunity. By using an empathetic approach with individuals, we can often have a dramatically positive effect on adjustment and outcome over time. Building trust can make all the difference. When an individual is compromised by stroke, the family can become the bridge between the patient and the staff by providing the vital information needed to build trust. The assessment process gives the staff an opportunity to develop a trusting relationship with the individual and their family members. Only the investment of time on the part of the staff will guarantee the opportunity to develop and establish the rapport needed for effective treatment outcomes.

    We have evaluated the angioscopic findings before and after various percutaneous techniques to treat 39 lesions in 32 cases of arteriosclerosis obliterans (ASO). We applied a laser (CL50: SLT, Japan), percutaneous transluminal angioplasty (PTA), and atherectomy -- either singly or in combination, with angioscopic luminal observation (angioscope: PF14L & PF18L Olympus, Japan) recorded before and after the treatments. In the case of a complete obstruction, we employed PTA as the first choice. We used a laser prior to PTA when the PTA guide-wire failed to penetrate the lumen. For eccentric and calcified lesions atherectomy was applied. A sufficient enlargement was obtained initially in 37 of the 39 lesions. The angioscopic observations after treatment revealed carbonization (3/5) and attachment of small thrombi (3/5) after using the laser, intimal rupture (3/8), dissection (2/8), flap formation (2/8), and attachment of small thrombi (4/8) after PTA, and attachment of small thrombi (9/19), flap formation (6/19), and dissection (2/19) after atherectomy. We established the efficacy of angioscopic assessment demonstrating beneficial clinical results. The angioscopic findings suggest that attachment of small thrombi may be responsible for a poor prognosis. Additional angioscopic observations with angiography are recommended for improved understanding of the luminal changes.

    Endotoxic material, commonly associated to biological reactions, is thought to be one of the most important constituents in water. This has become a very important topic because of the common interest in microbial products governed by the possible shift to water reuse for drinking purposes. In this light, this study was conducted to provide an assessment of endotoxic activity in reclaimed wastewater. A bacterial endotoxin test (LAL test) was applied to water samples from several wastewater treatment plants (WWTP) in Sapporo, Japan keeping in view the seasonal variation. Samples were taken from several points in WWTP (influent, effluent, return sludge, advanced treatment effluent). The findings of this study indicated that wastewater shows high endotoxin activity. The value of Endotoxin (Endo) to COD ratio in the effluent is usually higher than that of the influent. Moreover, it is found that wastewater contains initially endotoxic active material. Some of those chemicals are biodegradable and but most of them are non-biodegradable. Batch scale activated sludge studies were undertaken to understand the origin of endotoxic active material in the effluent. This study showed that those chemicals are mainly produced during biological reactions, more precisely during decay process. Moreover, raw wastewater (RWW) contains high amounts of organic matter having endotoxicity which remains in the effluent.

    This study surveyed the hospital wastewater characters focusing on antibiotic contamination in seven hospitals in Bangkok. It detected 19 antibiotics of which the high-frequent detection were quinolones such as ofloxacin + levofloxacin, norfloxacin, ciprofloxacin including sulfamethoxazole. Norfloxacin and ciprofloxacin appeared the highest concentrations of 12.11 and 9.60 μg/L, respectively. Most antibiotic concentrations in the wastewaters of the studied hospitals gave a good correlation (r (2)  = 0.77-0.99) to the amount of usage. In this study, batch acute toxicity tests were performed to assess the toxicity of hospital wastewater on mixed liquor, freshwater algae (Chlorella vulgaris and Scenedesmus quadricauda), and microcrustacean (Moina macrocopa). The hospital wastewaters could inhibit the mixed liquor growth and gave similar toxic levels among test species: algae and microcrustacean (9.81-13.63 and 2.62-3.09 TU, respectively). The conventional activated sludge (CAS) and rotating biological contactor (RBC) could remove fluoroquinolones and tetracycline via biomass adsorption. After treatment, most of treatment could reduce the toxicity. Nevertheless, the effluent gave slight toxicity on some test species which might be caused from chlorination and a common toxicant (NH3-N).

    Cue reactivity assessments have been widely used to assess craving and attention to cues among cigarette smokers. Cue reactivity has the potential to offer insights into treatment decisions; however, the use of cue reactivity in treatment studies has been limited. This study assessed the feasibility of using a virtual reality-based cue reactivity assessment approach (VR-NCRAS) during treatment. In a clinical smoking cessation treatment study, 46 treatment-seeking nicotine-dependent adult smokers were assessed for cue reactivity at baseline, Week 4, and Week 10 of treatment. Measures of cue reactivity included subjective craving and attention to cues after exposure to two neutral and two smoking cue environments. Overall, feasibility of using VR-NCRAS was demonstrated and these findings support the use of the cue reactivity assessment during treatment, which can inform treatment decisions.

    Cold atmospheric plasma is an ideal medium for non-destructive modification of vulnerable surfaces. One of the most promising medical applications of cold plasma treatment is wound healing. Potential advantages in wound healing have been demonstrated in vitro: the plasma does not necrotize the cells and does not affect the extracellular matrix [1], has clear bactericidal or bacteriostatic effects [2], and stimulates fibroblast cells towards faster attachment and proliferation [3]. However, safety issues, such as the potential cytotoxicity of the plasma must be clarified prior to clinical implementation. This work comprises the recent facts on sub-lethal plasma effects on mammalian cells, as well as studies on apoptosis induction and quantitative assessment of DNA damage. Fibroblast, smooth muscle and endothelial cells were treated using the standard cold plasma needle [1,2]; intra- and extracellular oxidant levels as well as the influence of the plasma on intracellular antioxidant balance were monitored using appropriate fluorescent markers [1]. We have studied long-term cellular damage was monitored using flow cytometry to determine the DNA profiles in treated cells. Dose-response curves were obtained: increased proliferation as well as apoptosis were visualized under different treatment conditions. The results from the in vitro studies are satisfying. [1] I.E.

    2005-08-05

    Staff of the King County Wastewater Treatment Division (WTD) have concern about the aftermath of a radiological dispersion event (RDE) leading to the introduction of significant quantities of radioactive material into the combined sanitary and storm sewer system in King County, Washington. Radioactive material could come from the use of a radiological dispersion device (RDD). RDDs include "dirty bombs" that are not nuclear detonations but are explosives designed to spread radioactive material (National Council on Radiation Protection and Measurements (NCRP) 2001). Radioactive material also could come from deliberate introduction or dispersion of radioactive material into the environment, including waterways and water supply systems. This document develops plausible and/or likely scenarios, including the identification of likely radioactive materials and quantities of those radioactive materials to be involved. These include 60Co, 90Sr, 137Cs, 192Ir, 226Ra, plutonium, and 241Am. Two broad categories of scenarios are considered. The first category includes events that may be suspected from the outset, such as an explosion of a "dirty bomb" in downtown Seattle. The explosion would most likely be heard, but the type of explosion (e.g., sewer methane gas or RDD) may not be immediately known. Emergency first responders must be able to quickly detect the radioisotopes previously listed, assess the situation, and deploy a response to contain and mitigate (if possible) detrimental effects resulting from the incident. In such scenarios, advance notice of about an hour or two might be available before any contaminated wastewater reaches a treatment plant. The second category includes events that could go initially undetected by emergency personnel. Examples of such a scenario would be the inadvertent or surreptitious introduction of radioactive material into the sewer system. Intact rogue radioactive sources from industrial radiography devices, well-logging apparatus, or

    The aim of this work was to develop a new system based on impedance spectroscopy to assess the heat treatment of previously cooked chicken meat by two experiments; in the first, samples were cooked at different temperatures (from 60 to 90 ℃) until core temperature of the meat reached the water bath temperature. In the second approach, temperature was 80 ℃ and the samples were cooked for different times (from 5 to 55 min). Impedance was measured once samples had cooled. The examined processing parameters were the maximum temperature reached in thermal centre of the samples, weight loss, moisture and the integral of the temperature profile during the cooking-cooling process. The correlation between the processing parameters and impedance was studied by partial least square regressions. The models were able to predict the studied parameters. Our results are essential for developing a new system to control the technological, sensory and safety aspects of cooked meat products on the whole meat processing line.

    Full Text Available The paper presents results from seed germination and root elongation tests for the evaluation of Lake Orta sediment contamination. The protocol for this test was developed after a literature survey and careful investigation of the proper conditions for obtaining the germination of commercially available seeds of several plants. Cucumis sativus, Lactuca sativa, and Lepidium sativum were finally chosen and used to detect the phytotoxicity of both liquid and solid phases of Lake Orta sediments. To assess whether exchange at the water – sediment interface could represent a hazard for the environment and the actual bioavailability of the toxicants present into the sediments, the phytotoxicity of samples collected in 1992, 1994, 1996, 1997, and 1998 from selected stations was tested on seeds of three different plant species (Lactuca sativa, Lepidium sativum and Cucumis sativus. The obtained results allow drawing distribution maps of the germination index, which confirm the persistence of toxic effects. However, the lake seems to positively respond to the restoration treatment, since the more contaminated layers of sediments are presently buried under less toxic sediments.

  12. Assessing fly ash treatment: Remediation and stabilization of heavy metals

    Fly ashes from Municipal Solid Waste (MSW), straw (ST) and co-combustion of wood (CW) are here analyzed with the intent of reusing them. Two techniques are assessed, a remediation technique and a solidification/stabilization one. The removal of heavy metals from fly ashes through the electrodialytic process (EDR) has been tried out before. The goal of removing heavy metals has always been the reuse of fly ash, for instance in agricultural fields (BEK). The best removal rates are here summarized and some new results have been added. MSW fly ashes are still too hazardous after treatment to even consider application to the soil. ST ash is the only residue that gets concentrations low enough to be reused, but its fertilizing value might be questioned. An alternative reuse for the three ashes is here preliminary tested, the combination of fly ash with mortar. Fly ashes have been substituted by cement fraction or aggregate fraction. Surprisingly, better compressive strengths were obtained by replacing the aggregate fraction. CW ashes presented promising results for the substitution of aggregate in mortar and possibly in concrete. © 2010 Elsevier Ltd.

    WIMSD-5B is a lattice code with a depletion capability for the analysis of reactor physics problems related to a design and safety. It is released from the OECD/NEA Data Bank in 1998 and is now being used widely for thermal research and power reactor calculations. The purpose of this study is to assess and improve the resonance treatment method in WIMSD- 5B, through the introduction of a new method with a high accuracy in treating the resonance, as one of the development works for WIMS/CANDU, which is being developed for replacing WIMS-AECL, for the physics analysis of CANDU reactors. In this article, we specifically describe the recent improvements in the resonance integral method using the Carlvik's approximation. As a result, a comparison for the resonance calculation on the CANDU-6 fuel lattice was performed between the WIMSD-5B code and the WIMS/CANDU code with the 69-energy groups of the ENDF/B-VI nuclear data library and the WIMS-AECL code with the 89-energy group of the ENDF/B-VI nuclear data library.

    Full Text Available 【Abstract】Objective:The rapid expansion of knowledge regarding the functional anatomy of hand and wrist, increasing functional demands of senior citizens and improved methodologies of achieving and maintaining anatomic restoration of distal radius fractures has generated a renewed interest in addressing these fractures in a more precise manner. The purpose of our study was to evaluate the difference in patients function among those treated by 1 closed reduction and Plaster of Paris cast, 2 distractor application, or 3 open reduction and internal fixation with a volar plate, and to assess the treatment choice for each particular fracture type. Methods: A prospective study was carried out on 60 patients with fractures of the distal end radius. Fractures were classified according to the AO classification into type A (extra-articular, type B (partial articular and type C (complete articular. After initial evaluation patients were taken up for either conservative or operative treatment and were followed up for two years. Results: Anatomical results were evaluated according to the Sarmiento’s modification of Lindstrom Criteria, which showed that excellent results were more frequent with open reduction and internal fixation using the plating technique. Clinical and functional results were evaluated according to the demerit point system of Gartland and Werley with Sarmiento modification, which was revealed to relate with the type of treatment techniques. Conclusion: There is no customized solution for all the fractures of the distal radius. The choice of treatment should be based on the fracture type, the patient’s characteristics, the patient’s demands and the treating surgeon’s experience and preference.

    2007-11-01

    Electrocoagulation (EC) may be a potential answer to environmental problems dealing with water reuse and rational waste management. The aim of this research was to assess the feasibility of EC-process for industrial contaminated effluents from copper production, taking into consideration technical and economical factors. EC-technology claims to offer efficient removal rates for most types of wastewater impurities at low power consumption and without adding any precipitating agents. Real wastewater from Saraka stream with high concentrations of heavy metals was provided by RTB-BOR, a Serbian copper mining and smelting complex. Runs were performed on a 10 l EC-reactor using aluminum plates as sacrificial electrodes and powered by a 40 A supply unit. Results concerning key factors like pH, conductivity and power consumption were measured in real time. Analysis of dissolved metal concentrations before and after treatment were carried out via ICP-OES and confirmed by an independent test via AAS. Several aspects were taken into account, including current density, conductivity, interfacial resistivity and reactor settings throughout the runs, in order to analyze all possible factors playing a role in neutralization and metal removal in real industrial wastewater. Electrode configurations and their effects on energy demand were discussed and exemplified based on fundamentals of colloidal and physical chemistry. Based on experimental data and since no precipitating agents were applied, the EC-process proved to be not only feasible and environmentally-friendly, but also a cost-effective technology The EC-technology provides strategic guidelines for further research and development of sustainable water management processes. However, additional test series concerning continuous operation must be still performed in order to get this concept ready for future large-scale applications.

    To discuss through retrospective study associated factors influencing orthodontists to develop orthodontic treatment plans and to calculate constituent ratio of a typical extraction in orthodontic treatment. Systematic sampling was performed among 7 344 orthodontic patients, who received orthodontic treatment from April 2012 to March 2014 in the Department of Orthodontics, West China Hospital of Stomatology, Sichuan University. The study included statistical data on factors that may influence development of treatment plans. Samples were used to calculate extraction-ratio and atypical-extraction-ratio. Research focused on associated factors influencing development of treatment plans while evaluating correlation significances of each factor. Finally, treatment outcomes of atypical-extraction were compared with those of typical-extraction. Among studied patients, 55.31% (406/734) received orthodontic extraction treatment. In orthodontic-extraction-treated patients, typical-extraction accounted for 59.11% (240/406), orthodontists-selected atypical-extraction accounted for 23.15% (94/406), and passive atypical-extraction accounted for 17.73% (72/406). With statistical analysis, we inferred associated factors influencing development of treatment plans as follows: sex and age of patients, sex of orthodontists, accurate condition of specific teeth, Angle's classification, and degree of midline deviation. Tooth loss before treatment also directly influences passive atypical-extraction. Statistically significant factors were not obtained. Significant difference of treatment outcome was not observed between atypical-extraction and typical-extraction-orthodontic treatment (P>0.05). Above mentioned factors may influence orthodontists to develop treatment plans. However, orthodontists should also consider expected results of treatment strategies to prepare individual treatment plans on the basis of comprehensive analysis.

  3. Radiological Instrumentation Assessment for King County Wastewater Treatment Division

    Energy Technology Data Exchange (ETDEWEB)

    2005-05-19

    The King County Wastewater Treatment Division (WTD) have concern about the aftermath of a radiological dispersion event (RDE) leading to the introduction of significant quantities of radioactive material into its combined sanitary and storm sewer system. Radioactive material could come from the use of a radiological dispersion device (RDD). RDDs include "dirty bombs" that are not nuclear detonations but are explosives designed to spread radioactive material. Radioactive material also could come from deliberate introduction or dispersion of radioactive material into the environment, including waterways and water supply systems. Volume 2 of PNNL-15163 assesses the radiological instrumentation needs for detection of radiological or nuclear terrorism, in support of decisions to treat contaminated wastewater or to bypass the West Point Treatment Plant (WPTP), and in support of radiation protection of the workforce, the public, and the infrastructure of the WPTP. Fixed radiation detection instrumentation should be deployed in a defense-in-depth system that provides 1) early warning of significant radioactive material on the way to the WPTP, including identification of the radionuclide(s) and estimates of the soluble concentrations, with a floating detector located in the wet well at the Interbay Pump Station and telemetered via the internet to all authorized locations; 2) monitoring at strategic locations within the plant, including 2a) the pipe beyond the hydraulic ram in the bar screen room; 2b) above the collection funnels in the fine grit facility; 2c) in the sampling tank in the raw sewage pump room; and 2d) downstream of the concentration facilities that produce 6% blended and concentrated biosolids. Engineering challenges exist for these applications. It is necessary to deploy both ultra-sensitive detectors to provide early warning and identification and detectors capable of functioning in high-dose rate environments that are likely under some scenarios, capable

    2008-01-01

    Clinical cases completed by the Indiana University School of Dentistry (IUSD) graduating orthodontic classes of 2004, 2005, and 2006 were assessed to determine factors that affect orthodontic treatment duration. The sample consisted of 455 consecutively finished patients who received comprehensive treatment in the full permanent dentition. They included optimally finished and prematurely terminated (early debond) patients. The American Board of Orthodontics (ABO) discrepancy index (DI) was used to evaluate the severity of the pretreatment malocclusion. A specifically designed treatment complexity index (TCI) was used to evaluate complexity based on treatment modalities. The ABO objective grading system (OGS) and the IUSD comprehensive clinical assessment (CCA) were used to evaluate the clinical outcome for all patients. The average treatment duration was 29 months. The mean DI, OGS, and CCA scores were 15.30, 23.34, and 4.48, respectively. Increased treatment length was associated with 0.022-in slot size brackets, percent of treatment spent in nickel-titanium wires, Class II malocclusion, increased DI score, and increased TCI score. In evaluating outcomes for 2004 through 2006, there was no significant relationship between treatment duration and clinical outcome as measured by the OGS and CCA scores. The DI and TCI are sensitive prospective indicators of treatment duration. After the introduction of a rigorous clinical protocol for controlling poor outcomes, because of patients exceeding predicted treatment times, the clinical results for this sample are independent of treatment duration.

    Hepatic encephalopathy (HE) is defined as a metabolically induced, potentially reversible, functional disturbance of the brain that may occur in acute or chronic liver disease. Standardized nomenclature has been proposed but a standardized approach to the treatment, particularly of persistent, episodic and recurrent encephalopathy associated with liver cirrhosis has not been proposed. This review focuses on the pathogenesis and treatment of HE in patients with cirrhosis. The pathogenesis and treatment of hepatic encephalopathy in fulminant hepatic failure is quite different and is reviewed elsewhere.

    Kinesiology is a complementary therapy assessing subtle change in manual muscle testing results to select individualised treatments. We report the exploratory 2-stage development and pilot of a sham kinesiology treatment for use in a clinical trial to evaluate the specific effects of this intervention. 1. To design, pilot and assess the credibility of a sham kinesiology treatment in a kinesiology-aware population. 2. To pilot the sham kinesiology in a cross-over study of sham versus real kinesiology, and to make an exploratory assessment of its credibility in a kinesiology-naïve population. 1. 10 kinesiology-aware volunteers received a specially designed sham treatment weekly for 5 weeks which was subject to a credibility assessment. 2. 10 kinesiology-naïve patients with low back pain were randomised to receive 4 real and 4 sham treatments in a cross-over design; the treatments were subject to a credibility assessment. 100% of participants found the sham protocol a credible treatment as measured by the credibility questionnaire. 100% of patients having real treatment first did not recognise that the second set of treatments were sham. Small numbers precluded the use of formal statistical tests. In this small sample it appeared feasible to deliver an apparently credible sham kinesiology treatment. This feasibility study has allowed us to develop a sham treatment for use in a larger prospective clinical trial of kinesiology in patients with low back pain. 2008 S. Karger AG, Basel.

Within the therapeutic arsenal, alongside surgery in the case of solid tumors, are the antitumor drugs and radiation that have been the treatment of choice in some instances. In recent years, immunotherapy has become an important therapeutic alternative, and is now the first choice in many cases. Nanotechnology has recently arrived on the scene, offering nanostructures as new therapeutic alternatives for controlled drug delivery, for combining imaging and treatment, applying hyperthermia, and providing directed target therapy, among others. These therapies can be applied either alone or in combination with other components (antibodies, peptides, folic acid, etc.. In addition, gene therapy is also offering promising new methods for treatment. Here, we present a review of the evolution of cancer treatments, starting with chemotherapy, surgery, radiation and immunotherapy, and moving on to the most promising cutting-edge therapies (gene therapy and nanomedicine. We offer an historical point of view that covers the arrival of these therapies to clinical practice and the market, and the promises and challenges they present.

    2016-06-01

    Full Text Available Acute myeloid leukemia (AML is a heterogeneous group of clonal malignant myeloid neoplasms. Malignant transformation of hematopoietic progenitor cell leads to clonal expansion and replacement of normal bone marrow cells with malignant cells leading to suppression of normal haematopoiesis. Advancements in our understanding of disease biology have allowed AML to be classified based on its gene expression profile, which includes previously identified cytogenetic subgroups, and distinct novel subgroups which have prognostic significance. Identification of mutations in DNMT3A and IDH 1 genes in cytogenetically normal AML (by gene sequencing helps to identify patients with poor prognosis. Redesigning the treatment regimen consisting of cytarabine and daunorubicin has improved the treatment outcomes without increase in the treatment-related mortality. Increasing the dose of daunorubicin to 90 mg/m2 improves complete remission rates without increasing treatment-related complications both in young and elderly patients. Cytarabine (200 mg/m2 in cycle I and 2 g/m2 in cycle 2 is shown to be as effective as high dose cytarabine (1000 mg/m2 twice daily in cycle 1and 2 g/m2 twice daily in cycle 2 and is associated with less treatment-related toxicities.

    2010-05-01

    The review focuses on one growing dimension of health care globalisation - medical tourism, whereby consumers elect to travel across borders or to overseas destinations to receive their treatment. Such treatments include cosmetic and dental surgery; cardio, orthopaedic and bariatric surgery; IVF treatment; and organ and tissue transplantation. The review sought to identify the medical tourist literature for out-of-pocket payments, focusing wherever possible on evidence and experience pertaining to patients in mid-life and beyond. Despite increasing media interest and coverage hard empirical findings pertaining to out-of-pocket medical tourism are rare. Despite a number of countries offering relatively low cost treatments we know very little about many of the numbers and key indicators on medical tourism. The narrative review traverses discussion on medical tourist markets, consumer choice, clinical outcomes, quality and safety, and ethical and legal dimensions. The narrative review draws attention to gaps in research evidence and strengthens the call for more empirical research on the role, process and outcomes of medical tourism. In concluding it makes suggestion for the content of such a strategy. Copyright 2010 Elsevier Ireland Ltd. All rights reserved.

    Recent advances in the developmental epidemiology, neurobiology, and treatment of pediatric anxiety disorders have increased our understanding of these conditions and herald improved outcomes for affected children and adolescents. This article reviews the current epidemiology, longitudinal trajectory, and neurobiology of anxiety disorders in youth. Additionally, we summarize the current evidence for both psychotherapeutic and psychopharmacologic treatments of fear-based anxiety disorders (e.g., generalized, social, and separation anxiety disorders) in children and adolescents. Current data suggest that these disorders begin in childhood and adolescence, exhibit homotypic continuity, and increase the risk of secondary anxiety and mood disorders. Psychopharmacologic trials involving selective serotonin reuptake inhibitors (SSRIs) and selective serotonin norepinephrine reuptake inhibitors (SSNRIs) are effective in pediatric patients with anxiety disorders and have generally demonstrated moderate effect sizes. Additionally, current data support cognitive behavioral therapy (CBT) for the treatment of these conditions in youth and suggest that the combination of psychotherapy + an SSRI may be associated with greater improvement than would be expected with either treatment as monotherapy.

Additionally, current data support cognitive-behavioral therapy (CBT) are efficacious in the treatment of these conditions in youth and that combination of CBT + an SSRI may be associated with greater improvement than would be expected with either treatment as monotherapy.

    Lata, Paul F; Elliott, Mary E

    2007-06-01

    Assessment of the patient with osteoporosis includes history and physical examination, laboratory testing, and imaging studies. Information gathered during this assessment assists clinicians in targeting strategies to prevent fractures. The medical history should contain items such as personal and family history of fractures, lifestyle, intake of substances such as vitamin D, calcium, corticosteroids, and other medications. The physical examination can reveal relevant information such as height loss and risk of falls. Bone mineral density (BMD), most commonly determined by dual-energy x-ray absorptiometry, best predicts fracture risk in patients without previous fracture. BMD testing is most efficient in women over 65 years old but is also helpful for men and women with risk factors. Serial BMD tests can identify individuals losing bone mass, but clinicians should be aware of what constitutes a significant change. Laboratory testing can detect other risk factors and can provide clues to etiology. Selection of laboratory tests should be individualized, as there is no consensus regarding which tests are optimal. Biochemical markers of bone turnover have a potential role in fracture risk assessment and in gauging response to therapy, but are not widely used at present. Clinicians should be aware of problems with vitamin D measurement, including seasonal variation, variability among laboratories, and the desirable therapeutic range. Careful assessment of the osteoporotic patient is essential in developing a comprehensive plan that reduces fracture risk and improves quality of life.

    On the basis of strong evidence, although primary monosymptomatic nocturnal enuresis (PMNE) is common and most children will outgrow the condition spontaneously, the psychological effect to the child can be significant and represents the main reason for treatment of these children. On the basis of international consensus panels, treatment of PMNE should be targeted toward the specific type of bedwetting patterns the child has, using bladder diary, sleep history, and daytime elimination concerns as a guide (Table 3). On the basis of international consensus panels, it is important for the primary care physician to be able to differentiate children with PMNE from children with nonmonosymptomatic nocturnal enuresis (NMNE) and secondary nocturnal enuresis. On the basis of international consensus panels, children with NMNE should have their underlying voiding or stool problem addressed before initiation of therapy for the nocturnal enuresis. On the basis of strong evidence, both the bedwetting alarm and desmopressin are considered first-line therapy for children with PMNE.

    Samuels, Joshua A.

    Vascular disease manifests itself in many different forms, including chronic ulcers which do not heal, impaired blood flow to the limbs, or damage to the natural reperfusion process. The current forms of assessing vascular disease are often subjective and provide incomplete knowledge about the tissue of interest. This work focused on developing non-invasive techniques to quantitatively evaluate three specific elements of vascular disease: diabetic ulcers, venous ulcers, and peripheral arterial disease. Diffuse Near Infrared Spectroscopy (DNIRS) was used to predict healing (82% positive predictive value) in diabetic ulcers after 4 weeks of assessment (sensitivity of 0.9 and specificity of 0.86; pulcers, using a low-frequency (20kHz), low intensity (ulcers compared to wounds which do not heal (p30 seconds) belonging to patients with PAD (pvascular health and the results obtained promise to develop new clinically relevant and quantitative techniques using non-invasive optical modalities.

  1. Delirium: assessment and treatment of patients with cancer. PART 2.

    Science.gov (United States)

    Brown, Michelle; Hardy, Kersten

    Delirium at the end of life may present significant ethical dilemmas in clinical practice: whether to simply treat it in order to maximise symptom relief, with the resulting side effect being palliative sedation, or to attempt to reverse delirium and risk prolonging suffering. Determining whether the delirium can be reversed involves comprehensive assessment using established tools, which may or may not provide the answer to the question posed. This article examines the evidence surrounding several assessment tools that have been suggested as effective in identifying delirium, and the consequences of various approaches to the management of delirium in a patient with a cancer diagnosis. It also considers the impact delirium may have on the health professional and those close to the patient.

  2. Mechanical assessment of grit blasting surface treatments of dental implants.

    Shemtov-Yona, K; Rittel, D; Dorogoy, A

    2014-11-01

    This paper investigates the influence of surface preparation treatments of dental implants on their potential (mechanical) fatigue failure, with emphasis on grit-blasting. The investigation includes limited fatigue testing of implants, showing the relationship between fatigue life and surface damage condition. Those observations are corroborated by a detailed failure analysis of retrieved fracture dental implants. In both cases, the negative effect of embedded alumina particles related to the grit-blasting process is identified. The study also comprises a numerical simulation part of the grit blasting process that reveals, for a given implant material and particle size, the existence of a velocity threshold, below which the rough surface is obtained without damage, and beyond which the creation of significant surface damage will severely reduce the fatigue life, thus increasing fracture probability. The main outcome of this work is that the overall performance of dental implants comprises, in addition to the biological considerations, mechanical reliability aspects. Fatigue fracture is a central issue, and this study shows that uncontrolled surface roughening grit-blasting treatments can induce significant surface damage which accelerate fatigue fracture under certain conditions, even if those treatments are beneficial to the osseointegration process.

    In this era of evidence-based mental health care, traditional forms of depth-oriented psychotherapy and psychological assessment have been marginalized in graduate training in clinical psychology. As a counterpoint, this article presents the evaluation and treatment of an adolescent client, along with an outcome assessment, and illustrates ways that aspects of traditional psychological testing, including the Rorschach (Exner, 1986) and the patient-examiner relationship, can enhance psychodiagnosis and treatment planning. Additionally, this case illustrates ways that test data can illuminate the concept of underlying disturbance and its utility in diagnostic formulation, treatment planning, and outcome assessment.

    The ways in which sleep can affect epilepsy, and epilepsy can influence sleep and wakefulness, are described. Different forms of sleep disturbance have been reported in patients with epilepsy, depending on the type of seizure disorder. Confusions between epilepsy and non-epileptic parasomnias can be a particular diagnostic problem but they can be avoided. Untreated sleep disturbance is likely to have harmful psychological, physical and family effects. Screening for sleep disturbance should be routine, and leading, if indicated, to precise diagnosis of the underlying sleep disorder on which choice of advice and treatment depends.

    The wide range of possibilities available in Radiotherapy with conformal fields cannot be covered experimentally. For this reason, dosimetrical and planning procedures are based on approximate algorithms or systematic measurements. Dose distribution calculations based on Monte Carlo (MC) simulations can be used to check results. In this work, two examples of conformal field treatments are shown: A prostate carcinoma and an ocular lymphoma. The dose distributions obtained with a conventional Planning System and with MC have been compared. Some significant differences have been found. (orig.)

    2017-02-28

    Malnutrition is a growing problem in the UK with as many as 14% of people aged over 65 at risk. It is of particular concern in care homes where more than one third of residents are undernourished. Weight loss is not the only symptom of malnourishment and nurses should examine any changes to a person's health and well-being to identify causes. Regular monitoring of patients' risk of malnutrition through use of screening assessments, such as the Malnutrition Universal Screening Tool, ensures undernourishment is identified early. As the population ages, it is more important than ever that the implications of malnutrition are recognised and addressed.

    Cross-cultural assessment and care frequently involve cross-language communication via a translator, interpreter, or bilingual worker. A resurgence of immigration, legalization of former illegal migrants, and refugee flight to the United States has increased the need for such special means of communication. Psychiatrists and other mental health professionals should develop conceptual models, skills, and experience for conducting cross-language interviews. This article provides information, terminology, and models for one aspect of this special clinical task, i.e., working with translators.

    1998-10-01

    Pulsatile tinnitus is a disorder that can be extremely disabling. Nonetheless, it has not been well-researched in the fields of psychology or behavioral therapy. This article describes the evaluation and behavioral treatment of a gentleman with pulsatile tinnitus. The evaluation included polygraphic assessment of vasomotor and electromyographic function both before and after treatment. The results show that the combination of lifestyle modifications and specific behavioral interventions were successful in modifying not only self-report indices of functioning, but also the underlying physiology related to the disorder. The potential role of the various treatment components and the value of including polygraphic assessment for informing treatment and evaluating outcome are discussed.

    Full Text Available Binge eating is a frequent disorder among obese patient, specialythose undergoing weight loss treatment. Binge eating disorder(BED is a newly defined diagnostic category, usually associatedwith psychopathology and overweight. Several clinical trialsinvolving psychoterapeutical interventions have shown thatcognitive beahavior therapy and interpersonal therapy can beeffective for the treatment of obese patients with BED.Pharmacotherapy can be also an useful tool for the control ofbinge eating, as part of a multidimensional therapeutic approach,associated to psychotherapy and eating behavior modification.Although the investigation of pharmacological agents for thetreatment of BED is still in its preliminary stages, somemedications have shown promising results in randomized clinicaltrials. Currently, three main classes of drugs have been evaluatedin randomized controlled trials: antidepressants, anti-obesityagents and anticonvulsants. The most studied drugs were theserotonina selective reuptake inhibitors (SSRIs. Fluoxetine,fluvoxamine, sertralina and citalopram have been shown to causemodest, but significant reduction in the frequency of bingeepisodes and body weight over the short term of the trials. Morerecently, sibutramina and topiramate have been shown tosignificantly reduce the binge eating behavior and the body weightin patients with obesity and binge eating.

  12. Probabilistic Assessment of Hypobaric Decompression Sickness Treatment Success

    2014-01-01

    The Hypobaric Decompression Sickness (DCS) Treatment Model links a decrease in computed bubble volume from increased pressure (DeltaP), increased oxygen (O2) partial pressure, and passage of time during treatment to the probability of symptom resolution [P(symptom resolution)]. The decrease in offending volume is realized in 2 stages: a) during compression via Boyle's Law and b) during subsequent dissolution of the gas phase via the O2 window. We established an empirical model for the P(symptom resolution) while accounting for multiple symptoms within subjects. The data consisted of 154 cases of hypobaric DCS symptoms along with ancillary information from tests on 56 men and 18 women. Our best estimated model is P(symptom resolution) = 1 / (1+exp(-(ln(Delta P) - 1.510 + 0.795×AMB - 0.00308×Ts) / 0.478)), where (DeltaP) is pressure difference (psid), AMB = 1 if ambulation took place during part of the altitude exposure, otherwise AMB = 0; and where Ts is the elapsed time in mins from start of the altitude exposure to recognition of a DCS symptom. To apply this model in future scenarios, values of DeltaP as inputs to the model would be calculated from the Tissue Bubble Dynamics Model based on the effective treatment pressure: (DeltaP) = P2 - P1 | = P1×V1/V2 - P1, where V1 is the computed volume of a spherical bubble in a unit volume of tissue at low pressure P1 and V2 is computed volume after a change to a higher pressure P2. If 100% ground level O2 (GLO) was breathed in place of air, then V2 continues to decrease through time at P2 at a faster rate. This calculated value of (DeltaP then represents the effective treatment pressure at any point in time. Simulation of a "pain-only" symptom at 203 min into an ambulatory extravehicular activity (EVA) at 4.3 psia on Mars resulted in a P(symptom resolution) of 0.49 (0.36 to 0.62 95% confidence intervals) on immediate return to 8.2 psia in the Multi-Mission Space Exploration Vehicle. The P(symptom resolution) increased

    The objective of this paper was to advance towards finding sustainable solutions to deal with biogas digestate and contribute to faster development of the market for digestate treatment products. The study compares digestate treatment costs through four different treatment plants, estimates the potential fertilizing and humus value (PFHV) of the derived products and allocates the cash flows to show the possible regional benefits. The treatment costs for the pre-dried solid fraction of digestate ranged from €19 to €23/tonne output. These costs may be covered by vending treatment products at a price reaching at least 34-41% of their PFHV (ca €55/tonne). Treatment of raw digestate generates high operating costs (€216-247/tonne output), much higher than the PFHV of the products (ca €35-51/tonne). For such systems either the treatment has to be financially subsidized by the authorities or €13-32/tonne input should be covered by the substrate deliverers as a disposal fee. Nevertheless, a well-prepared investment concept in this field may allow the local binding of up to 80% of total cash flows. Finally, the current difficult market situation of the treatment products can be primarily improved by clearing their legal status at European level.

    Denis Kiyoshi Fukumothi

    Full Text Available ABSTRACT OBJECTIVES: Evaluate the functional grade of these patients and to identify the types of complications found that influenced the average life span of endoprostheses the functions of the operated limb. METHODS: We analyzed 14 post-operative cases of endoprosthesis, patients with malignant bone tumors and aggressive benign bone tumors submitted to surgery between 2004 and 2014. The evaluation system used was proposed by Enneking, recommended by the Musculoskeletal Tumor Society (MSTS, in addition to the radiologic evaluation. RESULTS: Endoprosthesis are excellent choices for the treatment of bone tumors with limb preservation in relation to pain, strength, and patient's emotional acceptance. Another factor for good results is the immediate weight-bearing capacity, generating a greater independence. CONCLUSION: The authors conclude that all patients classified the therapy as excellent/good, regardless of the type of prosthesis used, extent of injury, and/or type of tumor resection performed.

    Hyperglycemia is a commonly encountered issue in critically ill patients in the intensive care setting. The presence of hyperglycemia is associated with increased morbidity and mortality, regardless of the reason for admission (e.g., acute myocardial infarction, status post-cardiovascular surgery, stroke, sepsis). However, the pathophysiology and, in particular, the treatment of hyperglycemia in the critically ill patient remain controversial. In clinical practice, several aspects must be taken into account in the management of these patients, including blood glucose targets, history of diabetes mellitus, the route of nutrition (enteral or parenteral), and available monitoring equipment, which substantially increases the workload of providers involved in the patients' care. This review describes the epidemiology, pathophysiology, management, and monitoring of hyperglycemia in the critically ill adult patient.

    Unorthodox therapies are used also by MS-patients very frequently. Not all procedures are harmless affecting only the purse. The medical expert working within the German health care system will also be called for questions of compensation of costs. A survey of some paradigmatic unorthodox treatments is given. While the law and the jurisdiction concerning the public health insurance fund pronounce clear standards in respect to the demands on the efficacy shown by modern (biomathematic) methods, it is essentially a more difficult task to bring the jurisdiction of the Federal Supreme Court (BGH) in harmony with basic requirements of a rational and scientific medicine. The interindividual and intraindividual course of MS is most variable, therefore it is very difficult to make a distinction between natural course and effects of a therapy in a single case while the only possibility to estimate individual therapeutic chance is a statistic evidence of efficacy in general.

    Problem behavior exhibited by individuals with autism can be disruptive to family traditions, such as decorating for the holidays. We present data for a 6-year-old girl who engaged in automatically reinforced pica and destruction of holiday decorations. Treatment was evaluated within an ABCDCD reversal design. During baseline (Phases A and B), we observed elevated rates of problem behavior. We implemented differential reinforcement of alternative behavior in Phase C to teach a response to compete with problem behavior. Little change in toy play or problem behavior occurred. In Phase D, we added a facial screen to the differential reinforcement procedures, which resulted in increases in toy play and decreases in problem behavior. Findings are discussed in terms of how interventions for problem behavior can promote alternative behavior while they facilitate household activities and traditions.

    2016-01-01

    Chronic fatigue--an overwhelming subjective feeling of mental or physical exhaustion--impacts patients' everyday functioning and quality of life, delays recovery after hemodialysis, and increases mortality. There are a number of factors that may perpetuate clinically significant fatigue among individuals with chronic kidney disease, including sleep disorders, depression, sedentary lifestyle, anemia, and chronic inflammation. Some of these factors (i.e., anemia and inflammation) are in the forefront of clinical attention, whereas the other contributing factors often remain unrecognized. This article provides a pragmatic overview of the definition, assessment, maintaining factors, and management of fatigue in chronic kidney disease. Given that chronic fatigue is a major determinant of patients' quality of life, nurses can bring about a fundamental improvement in patients' well-being if they recognize the most common fatigue-perpetuating factors and facilitate fatigue management interventions.

    The main objective of this work was to quantify and characterize the major indoor air contaminants present in different stages of a municipal WWTP, including microorganisms (bacteria and fungi), carbon dioxide, carbon monoxide, hydrogen sulfide ammonia, formaldehyde, and volatile organic compounds (VOCs). In general, the total bacteria concentration was found to vary from 60 to >52,560 colony-forming units (CFU)/m(3), and the total fungi concentration ranged from 369 to 14,068 CFU/m(3). Generally, Gram-positive bacteria were observed in higher number than Gram-negative bacteria. CO(2) concentration ranged from 251 to 9,710 ppm, and CO concentration was either not detected or presented a level of 1 ppm. H(2)S concentration ranged from 0.1 to 6.0 ppm. NH(3) concentration was <2 ppm in most samples. Formaldehyde was <0.01 ppm at all sampling sites. The total VOC concentration ranged from 36 to 1,724 μg/m(3). Among the VOCs, toluene presented the highest concentration. Results point to indoor/outdoor ratios higher than one. In general, the highest levels of airborne contaminants were detected at the primary treatment (SEDIPAC 3D), secondary sedimentation, and sludge dehydration. At most sampling sites, the concentrations of airborne contaminants were below the occupational exposure limits (OELs) for all the campaigns. However, a few contaminants were above OELs in some sampling sites.

    Occupational asthma refers to asthma induced by exposure in the working environment to airborne dusts, vapors, or fumes, with or without preexisting asthma. Potential triggers of occupational asthma are diverse and involve a variety of postulated mechanisms. After confirming the presence of asthma, diagnosis hinges on obtaining a detailed and accurate occupational and environmental history and documenting a temporal association of symptoms or signs with workplace exposure. Management of occupational asthma centers on prescribing standard asthma therapies in conjunction with instituting preventive strategies, such as appropriate avoidance of environmental triggers, providing work restrictions, and using environmental controls and/or personal respiratory protection. If a worker is determined to be ill or injured, there are a variety of compensation systems that are designed to protect workers financially from disability related to respiratory impairments; however, the administrative process is frequently difficult to navigate for patients and their providers. Focusing on obtaining a detailed occupational and environmental history, establishing clear objective data to substantiate illness, and estimating or apportioning workplace contribution to the condition is important for the diagnosis and treatment of this relatively common form of asthma.

    Full Text Available Aspergillus spp. are a group of filamentous molds that were first described due to a perceived similarity to an aspergillum, or liturgical device used to sprinkle holy water, when viewed under a microscope. Although commonly inhaled due to their ubiquitous nature within the environment, an invasive fungal infection (IFI is a rare outcome that is often reserved for those patients who are immunocompromised. Given the potential for significant morbidity and mortality within this patient population from IFI due to Aspergillus spp., along with the rise in the use of therapies that confer immunosuppression, there is an increasing need for appropriate initial clinical suspicion leading to accurate diagnosis and effective treatment. Voriconazole remains the first line agent for therapy; however, the use of polyenes, novel triazole agents, or voriconazole in combination with an echinocandin may also be utilized. Consideration as to which particular agent and for what duration should be made in the individual context for each patient based upon underlying immunosuppression, comorbidities, and overall tolerance of therapy.

    Raw milk (RM), reconstituted condensed milk (CM) and three types of reconstituted milk powders (SMPs) were heated indirectly at 80-140°C for 4 s. Native β-lactoglobulin after 90°C treatment of RM was 1132±167 mg/L but no reliable quantities were estimated at temperatures >100°C, whereas 218±43 mg/L residual α-lactalbumin were found at 130°C. Average lactulose contents from 51 to 1549 mg/L were detected at ⩾100°C; average furosine was 1.9 and 126.5 mg/L in raw and 140°C treated milks respectively. The behaviour of heated CM was similar to that of heated RM except for higher furosine concentration. Reconstituted SMPs contained high quantities of lactulose and furosine, the ratio of which was lower than in similarly treated RM. Among the market milks analysed, the group of high-pasteurised milks was highly variable; i.e. native β-lactoglobulin was 69-2831 mg/L, lactulose 0-824 mg/L and furosine 3.3-68.8 mg/L.

    Extending the frying-life of oils is of commercial and economic importance. Due to this fact, assessment on the thermal stability of frying oils could provide considerable savings to the food processors. In this study, the physico-chemical properties of five palm products mainly palm oil, single-fractionated palm olein, double-fractionated palm olein, red palm olein and palm-based shortening during 80 hours of heating at 180 degrees C were investigated. Heating properties of these products were then compared with that of high oleic sunflower oil, which was used as reference oil. The indices applied in evaluating the quality changes of oils were free fatty acid, smoke point, p-anisidine value, tocols, polar and polymer compounds. Three palm products i.e. palm oil, single-fractionated palm olein and double-fractionated palm olein were identified to be the most stable in terms of lower formation of free fatty acid, polar and polymer compounds as well as preserving higher smoke point and tocols content compared to the other three oils. The low intensity of hydrolytic and oxidative changes due to prolonged heating, suggests that these palm products are inherently suitable for frying purposes.

    Extreme climate events play an important and potentially lasting role in terrestrial carbon cycling and storage. In particular, satellite and in-situ measurements have shown that forest recovery time following severe drought can extend several years beyond the return to normal climate conditions. However, terrestrial ecosystem models generally do not account for the physiological mechanisms that cause these legacy effects and, instead, assume complete and rapid vegetation recovery from drought. Using a suite of fifteen land surface models from the Multi-scale Synthesis and Terrestrial Model Intercomparison Project (MsTMIP), we assess models' ability to capture legacy effects by analyzing the spatial and temporal extent of modeled vegetation response to the 2005 Amazon drought. We compare the simulated primary production and ecosystem exchange (GPP, NPP, NEE) to previous recovery-focused analysis of satellite microwave observations of canopy backscatter. Further, we evaluate the specific model characteristics that control the timescale and magnitude of simulated vegetation recovery from drought. Since climate change is expected to increase the frequency and severity of extreme climate events, improving models' ability to simulate the legacy effects of these events will likely refine estimates of the land carbon sink and its interannual variability.

    Medication adherence rates strongly depend on favorable disease outcomes. It is known that medication adherence rates are lower for topical treatment than for systemic treatment. However, to date no validated instrument for the assessment of adherence factors in topical treatment is available. The aim of this study was to develop a new questionnaire to assess adherence risk factors in topical treatment. The development of the Topical Therapy Adherence Questionnaire (TTAQ) and Patient Preference Questionnaire (PPQ) was based on a systematic literature review, and qualitative patient focus interviews and expert focus groups' input. The psychometric properties and comprehensibility of the TTAQ and PPQ were assessed in a feasibility study with 59 psoriasis patients. Our first preliminary results indicate that the TTAQ and PPQ are psychometrically sound and reliable measures for the assessment of factors influencing topical treatment adherence. The questionnaires are currently being further developed and various parameters (e.g., time point of assessment) are currently being tested in an exploratory pilot study with ca. 2,000 psoriasis patients receiving topical treatment in a European clinical trial. The use of the final versions of TTAQ and PPQ in clinical practice may facilitate the early identification of specific non-adherence factors in patients under topical treatment, which could enable designing and applying adherence-enhancing interventions according to the patient's individual needs.

    Talkha power plant is the only power plant located in El-Mansoura. It generates electricity using two different methods by steam turbine and gas turbine. Both plants drew water from River Nile (208 m3 /h). The Nile raw water passes through different treatment processes to be suitable for drinking and operational uses. At Talkha power plant, there are two purification plants used for drinking water supply (100 m3/h) and for water demineralization supply (108 m3/h). This study aimed at studying the efficiency of the water purification plants. For drinking water purification plant, the annual River Nile water characterized by slightly alkaline pH (7.4-8), high annual mean values of turbidity (10.06 NTU), Standard Plate Count (SPC) (313.3 CFU/1 ml), total coliform (2717/100 ml), fecal coliform (0-2400/100 ml), and total algae (3 x 10(4) org/I). The dominant group of algae all over the study period was green algae. The blue green algae was abundant in Summer and Autumn seasons. The pH range, and the annual mean values of turbidity, TDS, total hardness, sulfates, chlorides, nitrates, nitrites, fluoride, and residual chlorine for purified water were in compliance with Egyptian drinking water standards. All the SPC recorded values with an annual mean value of 10.13 CFU/1 ml indicated that chlorine dose and contact time were not enough to kill the bacteria. However, they were in compliance with Egyptian decree (should not exceed 50 CFU/1 ml). Although the removal efficiency of the plant for total coliform and blue green algae was high (98.5% and 99.2%, respectively), the limits of the obtained results with an annual mean values of 40/100 ml and 15.6 org/l were not in compliance with the Egyptian decree (should be free from total coliform, fecal coliform and blue green algae). For water demineralization treatment plant, the raw water was characterized by slightly alkaline pH. The annual mean values of conductivity, turbidity, and TDS were 354.6 microS/cm, 10.84 NTU, and 214

    Full Text Available Abstract Background The side effects and burden of anticoagulant treatments may contribute to poor compliance and consequently to treatment failure. A specific questionnaire is necessary to assess patients' needs and their perceptions of anticoagulant treatment. Methods A conceptual model of expectation and satisfaction with anticoagulant treatment was designed by an advisory board and used to guide patient (n = 31 and clinician (n = 17 interviews in French, US English and Dutch. Patients had either atrial fibrillation (AF, deep venous thrombosis (DVT, or pulmonary embolism (PE. Following interviews, three PACT-Q language versions were developed simultaneously and further pilot-tested by 19 patients. Linguistic validations were performed for additional language versions. Results Initial concepts were developed to cover three areas of interest: 'Treatment', 'Disease and Complications' and 'Information about disease and anticoagulant treatment'. After clinician and patient interviews, concepts were further refined into four domains and 17 concepts; test versions of the PACT-Q were then created simultaneously in three languages, each containing 27 items grouped into four domains: "Treatment Expectations" (7 items, "Convenience" (11 items, "Burden of Disease and Treatment" (2 items and "Anticoagulant Treatment Satisfaction" (7 items. No item was deleted or added after pilot testing as patients found the PACT-Q easy to understand and appropriate in length in all languages. The PACT-Q was divided into two parts: the first part to measure the expectations and the second to measure the convenience, burden and treatment satisfaction, for evaluation prior to and after anticoagulant treatment, respectively. Eleven additional language versions were linguistically validated. Conclusion The PACT-Q has been rigorously developed and linguistically validated. It is available in 14 languages for use with thromboembolic patients, including AF, PE and DVT patients

    2016-06-01

    Portable water plays a vital role in improving human life, particularly in controlling the spread of diseases. However, problems associated with lack of potable water are still common especially in developing countries including Malawi. Until now little information exists on the effectiveness of available commercial coagulants used by national water boards in Malawi. Therefore, this study was undertaken in Southern Region Water Board (SRWB) to investigate the efficiency of polymeric coagulants (sufdfloc 3850 and algaefloc 19s) in turbidity reduction comparative with inorganic coagulant (aluminium sulphate) at Zomba, Liwonde, Mangochi, Chikwawa and Mulanje Treatment plants. The jar test method was used to determine the effectiveness of the water coagulants. The results revealed that sudfloc 3850 was most effective in reducing turbidity at Mangochi (99.4 ± 0.06%) and Liwonde (97.2 ± 0.04%) using 0.4 mg L-1 flocculant dose. The Zomba, Mulanje and Chikwawa plants gave 19.56 ± 0.03%, 29.23 ± 0.02% and 9.43 ± 0.02% total reductions respectively. Algaefloc 19s afforded the highest turbidity reduction at Liwonde and Mangochi plants (98.66 ± 0.06 and 97.48 ± 0.05% at a dose of 0.4 and 0.6 mg L-1 respectively), while Chikwawa provided the lowest (9.52 ± 0.01%). At the Zomba and Mulanje plants 20.5 ± 0.03% and 28.4 ± 0.04% reductions were obtained respectively. The inorganic flocculant, alum provided a 99.0 ± 0.05% and 98.6 ± 0.04% reduction at a dose of 4.0 mg L-1 and 6.0 mg L-1 at Zomba and Liwonde plants respectively. The lowest reductions in turbidity were achieved at Chikwawa (7.50 ± 0.01%), Mangochi (12.97 ± 0.02%) and Mulanje (25.00 ± 0.02). The best and optimum pH ranges for polymeric and inorganic coagulants were 7.20-7.80 and 7.35 to 7.57 respectively. The results further revealed that sudfloc 3850 and algaefloc 19s achieved faster formation of heavy flocs than alum. At 0.4 mg L-1 flocculant dosage sudfloc 3850 and algaefloc 19s required ten times

    Full Text Available The main iatrogenic effects associated with orthodontic treatment refer to: influence of orthodontic rings on the periodontal tissue; gum retractions; the effect of the orthodontic treatment on dental root (root resorption; the effect of the orthodontic treatment on alveolar bone height; mobility and pain associated with orthodontic treatment. AIM of the study: To assess the degree of root resorption of incisors, after orthodontic treatment, on a group of 48 adults with dental-maxillary abnormalities. Materials and method: The study included 48 young adult patients, 35 women and 13 men aged 18 to 30 years, who had received fixed orthodontic treatment. To assess the degree of root resorption (changes at root level and apical contour length, apical radiographies were taken in the maxillary incisors and jaw both at the beginning and end of the orthodontic treatment. Results: Out of the 239 incisors examined at the beginning of orthodontic treatment, 163 showed code 0, meaning 88.1%, and 50 showed a slight squash apex (code 1, respectively 10.9%. Only 1% of all incisors assessed presented mild and severe root resorption. Conclusions: The results of the study show that, generally, an adult orthodontic treatment, applied for functional and aesthetic objectives, may have clinically acceptable iatrogenic effects.

    Full Text Available Carmen Rosa, Udi Ghitza, Betty TaiCenter for the Clinical Trials Network, National Institute on Drug Abuse, Bethesda, MD, USAAbstract: Based on recommendations from a US Institute of Medicine report, the National Institute on Drug Abuse established the National Drug Abuse Treatment Clinical Trials Network (CTN in 1999, to accelerate the translation of science-based addiction treatment research into community-based practice, and to improve the quality of addiction treatment, using science as the vehicle. One of the CTN's primary tasks is to serve as a platform to forge bi-directional communications and collaborations between providers and scientists, to enhance the relevance of research, which generates empirical results that impact practice. Among many obstacles in moving research into real-world settings, this commentary mainly describes challenges and iterative experiences in regard to how the CTN develops its research protocols, with focus on how the CTN study teams select and utilize assessment instruments, which can reasonably balance the interests of both research scientists and practicing providers when applied in CTN trials. This commentary also discusses the process by which the CTN further selects a core set of common assessment instruments that may be applied across all trials, to allow easier cross-study analyses of comparable data.Keywords: addiction, assessment, drug abuse treatment, drug dependence, NIDA Clinical Trials Network, substance use disorder

    2014-05-01

    We report the results of a social validity assessment that was administered to special education service providers (N = 44) to document the acceptability and effectiveness ratings of several treatment integrity training methods. The participants judged performance feedback as the most likely method to improve their treatment integrity, followed by avoidance (negative reinforcement) of supervision meetings, online training, and financial incentive. Performance feedback was also rank-ordered as most effective among the four training methods. We discuss the merits of social validity assessment in designing programs for enhancing treatment integrity among practitioners within educational and clinical settings.

    This case study describes the functional assessment and treatment of aggressive and destructive behaviors in a 14-year-old male child with a history of physical abuse. Evaluation was performed in a classroom within a residential school setting. Functional assessment in forms of indirect and descriptive methods was used to generate hypotheses regarding sources of behavioral control. A treatment plan that combined multi-level differential reinforcement of other behavior (DRO) and positive reinforcement for task completion was implemented based on the outcome of functional assessment. Treatment was associated with a gradual and steady reduction in challenging behaviors with near-zero rates achieved at follow-up. This case provides an example of clinical intervention for behavior disorders commonly observed in children who have been abused physically and a hypothesis-driven model of treatment formulation.

    Full Text Available The aim of this study was to provide an overview of the literature available on dynamic contrast-enhanced computed tomography (DCE-CT as a tool to evaluate treatment response in patients with lung cancer. This systematic review was compiled according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA guidelines. Only original research articles concerning treatment response in patients with lung cancer assessed with DCE-CT were included. To assess the validity of each study we implemented Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2. The initial search yielded 651 publications, and 16 articles were included in this study. The articles were divided into groups of treatment. In studies where patients were treated with systemic chemotherapy with or without anti-angiogenic drugs, four out of the seven studies found a significant decrease in permeability after treatment. Four out of five studies that measured blood flow post anti-angiogenic treatments found that blood flow was significantly decreased. DCE-CT may be a useful tool in assessing treatment response in patients with lung cancer. It seems that particularly permeability and blood flow are important perfusion values for predicting treatment outcome. However, the heterogeneity in scan protocols, scan parameters, and time between scans makes it difficult to compare the included studies.

    Tsui, Patricia; Deptula, Andrew; Yuan, Derek Y

    2017-06-01

    This paper examines the overlap of conversion disorder with chronic pain conditions, describes ways to assess for conversion disorder, and provides an overview of evidence-based treatments for conversion disorder and chronic pain, with a focus on conversion symptoms. Conversion disorder is a significant problem that warrants further study, given that there are not many well-established guidelines. Accurate and timely assessment should help move treatment in a more fruitful direction and avoid unnecessary medical interventions. Advances in neuroimaging may also help further our understanding of conversion disorder. Creating a supportive environment and a collaborative treatment relationship and improving understanding of conversion symptoms appear to help individuals diagnosed with conversion disorder engage in appropriate treatments. Novel uses of earlier treatments, such as hypnosis and psychodynamic approaches, could potentially be beneficial and require a more vigorous and systematic study. There are treatments that produce significant improvements in functioning and reduction of physical symptoms from conversion disorder even for very severe cases. Hypnotherapy, cognitive behavioral therapy, and inpatient multidisciplinary treatment with intensive physiotherapy for severe cases have the most evidence to support reduction of symptoms. Components of treatment for conversion disorder overlap with treatments for chronic pain and can be used together to produce therapeutic effects for both conditions. Treatment needs to be tailored for each individual's specific symptoms.

Objectives: To investigate Danish general practitioners' (GPs') assessment...... of a set of internationally developed quality indicators and to explore if there is an association between the GPs' assessment of the indicators and their practice characteristics as well as their antibiotic prescription pattern. Methods: A total of 102 Danish GPs were invited to assess the 41 quality...... indicators. The GPs were categorized into two groups according to their assessment of indicators. Data concerning practice characteristics and antibiotic treatment were obtained during a three-week registration of patients with RTIs and were linked to the GPs' assessments of the indicators. Results: A total...

    The treatment of children with pervasive developmental disorders (PDD) has not been systematically assessed in French day-care units. In this prospective study, 11 children with a diagnosis of PDD were followed up for 2years in a day-care unit in the Marseille university hospital. The treatment they received is based on an initial assessment by the "Centre Ressources Autisme" (CRA PACA) and further included a continued observation of the child and an assessment of the child's abilities and needs. This treatment used various therapeutic approaches 10h weekly and also included parental counseling and coordinated work with schools. Treatment in our day-care unit can be categorized as eclectic, non-intensive therapy. It is based on methods such as TEACCH (Treatment and Education of Autistic and related Communication handicapped Children), Floor Time Play, speech and language therapy, developmental therapy, and psychotherapy. International studies on intensive behavioral therapies suggest that this treatment is superior to non-behavioral and/or non-intensive treatment. They suggest its efficiency is due both to the nature of the treatment (behavioral) and to its intensity (more than 25h a week). In this study, the CRA diagnosed children using the ADI and ADOS. The 11 children (mean age, 3years 5months) were tested twice, with the Vineland and CARS scales. The first assessment was on admission to the day hospital and the second was 2years later. The results showed developmental progress with a mean increase of 13.5 months at the Vineland Scale, and a decrease of the autism severity score on the CARS. The treatment presented here proves to be efficient; if compared to similar results in international studies, we obtained better results than their eclectic intensive or non-intensive treatment comparison group.

    The blueprints for the assessment, treatment, and future study of catatonia in autism spectrum disorders (ASDs), which are submitted in this chapter aim to increase early recognition and treatment of catatonia in ASDs, show the urgency of controlled treatment trials, and increase collaborative and interdisciplinary research into the co-occurrence of these two enigmatic disorders. Catatonia should be assessed in any patient with ASDs when there is an obvious and marked deterioration in movement, pattern of activities, self-care, and practical skills, compared with previous levels, through a comprehensive diagnostic evaluation of medical and psychiatric symptoms. A formal diagnosis should be ascertained using ASD specific criteria for catatonia that takes into account baseline symptoms like muteness, echophenomena, stereotypy, negativism, or other psychomotor abnormalities. Any underlying medical and neurological conditions should be treated, and culprit medications or other substances that may cause catatonia should be eliminated. Separate treatment blueprints are presented for mild, moderate, and severe catatonia, featuring combinations of a psychological approach developed by Shah and Wing and medical treatments that have shown efficacy in catatonia: lorazepam challenge, lorazepam trial, lorazepam continuation, and bilateral electroconvulsive therapy (ECT). These treatment modalities in themselves are well established. Side effects and complications are known and manageable. Legal, ethical, and practice guidelines governing all treatment aspects should be followed. The treatment blueprints should be viewed as best estimates pending future controlled studies. The blueprint for the future study of catatonia in ASDs describes promising clinical and preclinical research avenues. Longitudinal studies need to assess the possible effect of early recognition and adequate treatment of catatonia in ASDs in order to avoid the impairment associated with chronicity. Effects of

    Because pain is quite subjective, the accurate assessment of pain is very difficult in the patients with impaired communication ability. The current most valid and reliable behavioral pain scales used to assess pain in adult ICU patients are the Behavioral Pain Scale and the Critical-Care Pain Observation Tool. Once pain has been accurately assessed using these methods, various pharmacologic and non-pharmacologic therapies should be performed by the multidisciplinary care team. Accurate assessment and proper treatment of pain in adult ICU patients will improve patients outcome, which reduces the stress response and decreases the risk of post-traumatic stress disorder.

    Objective To review the applications of magnetic resonance imaging (MRI) techniques in assessing treatment response to gamma knife radiosurgery for brain tumors.Data sources Published articles about assessing treatment response to gamma knife radiosurgery for brain tumors were selected using PubMed. The search terms were "MRI", "gamma knife" and "brain tumors".Study selection Articles regarding the MRI techniques using for early assessment of treatment response of gamma knife were selected.Results MRI techniques, especially diffusion weighted imaging, perfusion weighted imaging, magnetic resonance spectroscopy, are useful for early assessment of treatment response of gamma knife by detecting the hemodynamic, metabolic, and cellular alterations. Moreover, they can also provide important information on prognosis.Conclusions Diffusion weighted imaging, perfusion weighted imaging and magnetic resonance spectroscopy can provide early assessment of treatment response of gamma knife for brain tumors, and also information of tumor progression or recurrence earlier than conventional MRI. But there are still many questions to be answered which should be based on the development and advancement of MRI and related disciplines.

    Many factors affect the assessment and treatment of pain, among them being the knowledge and attitudes of clinical staff. The goal of this work was to determine the opinions and attitudes of clinical staff from two hospitals on the different aspects of the assessment and treatment of children's pain. A cross-sectional, descriptive study was conducted using a self-administered questionnaire issued to clinical staff. The questionnaire was given to the professionals, doctors, and nursing staff of the paediatric services of two hospitals, and to an incidental sample of paediatric doctors. Of the 146 questionnaires sent out, 105 were completed. Participants indicated that standardised scales and physiological recordings were the least frequently used methods to assess children's pain. Participants considered that pharmacological techniques for the treatment of pain were used more frequently than non-pharmacological techniques, at all ages. Participants acknowledged being significantly more knowledgeable about pharmacological methods to relieve paediatric pain than about non-pharmacological methods. There is margin for improvement in systems for the assessment and treatment of children's pain as regards the more frequent and standardised use of techniques and standardised tools for the assessment of pain, and the greater administration of non-pharmacological strategies for its treatment.

    Loss of body sensations is common after stroke, impacting negatively on recovery and performance of activities of daily living. Despite advances in the evidence for the assessment and treatment of somatosensory impairment post-stroke, the translation from research into clinical practice has been slow. The aim of this study was to determine current clinical practice of occupational therapists and physiotherapists in the assessment and treatment of somatosensory impairment post-stroke. A cross-sectional, self-administered online survey of occupational therapists and physiotherapists currently working with stroke clients in Australian health organisations, identified through an audit of stroke rehabilitation services and a professional member association. 172 clinicians, 62.8% occupational therapists and 37.2% physiotherapists currently working with stroke clients completed the survey. Most respondents (93.0%) indicated routinely assessing for sensory loss in stroke clients. The most commonly used measures were light touch and proprioception, with the majority (70.4%) not using standardised measures. Most respondents (97.7%) reported providing treatment to address sensory impairment, with compensatory strategies and sensory re-education the two most frequently reported. Evidence-based treatment choices were not common and therapists frequently relied on colleagues' opinions and previous experience to inform practice. Therapists commonly experienced barriers to implementing evidence-based sensory rehabilitation, including time constraints, large caseloads and lack of access to evidence-based somatosensory assessment and treatment resources. Most therapists perceived somatosensory assessment and treatment as important. However, frequently utilised methods lack a sound theoretical or empirical basis. Despite published evidence regarding somatosensory assessment and treatment, an evidence-practice gap exists. © 2015 Occupational Therapy Australia.

    The reclamation and reuse of wastewater is one of the possible ways to relieve the serious fresh water resource crisis in China.Efficient reclamation treatment technologies ensure the safe reuse of reclaimed water.In order to screen out and evaluate technologies appropriate for reclamation treatment,a great deal of efforts have been brought to bear.In the present study,a toxicity-based method including a Photobacterium phosphorewn test for acute toxicity and SOS/umu test for genotoxicity,accompanied by the traditional physicochemical parameters DOC (dissolved organic carbon) and UV254 (absorbance at 254 nm),was used to measure the treatment performance of different reclamation processes,including the anaerobic-anoxic-oxic biological process (A2O) and subsequent physical/chemical reclamation processes (ultrafiltration,ozonation,chlorination).It was found that for the secondary effluent after the A2O process,both the toxicity and physicochemical indices had greatly decreased compared with those of the influent.However,chemical reclamation processes such as ozonation and chlorination could possibly raise toxicity levels again.Fortunately,the toxicity elevation could be avoided by optimizing the ozone dosage and using activated carbon after ozonation.It was noted that by increasing the ozone dosage to 10 mg/L and employing activated carbon with more than 10 min hydraulic retention time,toxicity elevation was controlled.Furthermore,it was shown that pre-ozonation before activated carbon and chlorination played an important role in removing organic compounds and reducing the toxicity formation potential.The toxicity test could serve as a valuable tool to evaluate the performance of reclamation processes.

    Over the past 15 years, the incidences of hepatitis A and B virus infection in the United States have declined significantly. By contrast, the incidence of hepatitis C virus infection, formerly stable or in decline, has increased by 75% since 2010. Suboptimal therapies of the past, insufficient provider awareness, and low screening rates have hampered efforts to improve diagnosis, management, and treatment of viral hepatitis. New screening recommendations, innovations in assessment and treatment, and an updated action plan from the U.S. Department of Health and Human Services (HHS) seem likely to lead to significant progress in the coming years. This article reviews the epidemiology, natural history, and diagnosis of viral hepatitis; discusses new screening recommendations, assessment tools, and treatments; and outlines the HHS action plan, focusing on the role of nurses in prevention and treatment.

    Many veterans returning from service in Afghanistan or Iraq suffer from post-traumatic stress disorder or mild traumatic brain injury. Treating these conditions can be challenging because of high rates of relapse and associated memory impairments. We report on a pilot study that assessed the utility of mobile health (mHealth) technologies, including personal digital assistant-based ecological momentary assessment and two-way interactive text (SMS) messaging, for providing treatment feedback to clinicians, encouraging and motivating veterans throughout treatment, and monitoring participants for relapse after treatment discharge. The results of the pilot suggest that mHealth technologies are feasible adjuncts to traditional mental treatment in the veteran population. Additional work is needed to establish the degree of clinical and economic value.

    Ramsay, J Russell

    2017-01-01

    Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental syndrome that emerges in childhood or early adolescence and persists into adulthood for a majority of individuals. There are many other adults with ADHD who may not seek out evaluation and treatment until adulthood, having been able to “get by” before struggling with inattention, hyperactivity, and/or impulsivity in adulthood, in addition to facing the associated features of disorganization, poor time management, and procrastination among many others. A lifetime diagnosis of ADHD is associated with a wide range of life impairments, which makes a comprehensive and accurate diagnostic assessment essential in order to obtain appropriate treatment. Moreover, while there are effective medical and psychosocial treatments for ADHD, it is important to be able to track treatment response in order to evaluate whether adjustments in specific interventions are needed or referrals for adjunctive treatments and supports are indicated to facilitate optimal therapeutic outcomes. The goal of this article is to provide a clinically useful review of the various measures that practicing clinicians can use to aid in the diagnostic assessment and monitoring of psychosocial and medical treatment of ADHD in adult patients. This review includes various structured interviews, screening scales, adult ADHD symptom inventories, measures of associated features of ADHD, as well as ratings of impairment and functioning which can be adapted to clinicians’ practice needs in order to track treatment progress and optimize treatments for adults with ADHD.

    2015-02-01

    This study uses a systems-level modeling approach to illustrate a novel synergy between municipal wastewater treatment and large-scale algaculture for production of bio-energy, whereby algae-mediated tertiary treatment provides efficient removal of unregulated, strongly estrogenic steroid hormones from the secondary effluent. Laboratory results from previously published studies suggested that algae-mediated treatment could deliver roughly 75-85% removal of a model estrogen (17β-estradiol) within typical algae pond residence times. As such, experimental results are integrated into a comprehensive life cycle assessment (LCA) framework, to assess the environmental performance of an algae-based tertiary treatment system relative to three conventional tertiary treatments: ozonation, UV irradiation, and adsorption onto granular activated carbon. Results indicate that the algae-mediated tertiary treatment is superior to the selected benchmarks on the basis of raw energy return on investment (EROI) and normalized energy use per mass of estrogenic toxicity removed. It is the only tertiary treatment system that creates more energy than it consumes, and it delivers acceptable effluent quality for nutrient and coliform concentrations while rendering a significant reduction in estrogenic toxicity. These results highlight the dual water and energy sustainability benefits that accrue from the integration of municipal wastewater treatment and large-scale algae farming.

    Advanced nutrient removal processes, while improving the water quality of the receiving water body, can also produce indirect environmental and health impacts associated with increases in usage of energy, chemicals, and other material resources. The present study evaluated three levels of treatment for nutrient removal (N and P) using 27 representative treatment process configurations. Impacts were assessed across multiple environmental and health impacts using life-cycle assessment (LCA) following the Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI) impact-assessment method. Results show that advanced technologies that achieve high-level nutrient removal significantly decreased local eutrophication potential, while chemicals and electricity use for these advanced treatments, particularly multistage enhanced tertiary processes and reverse osmosis, simultaneously increased eutrophication indirectly and contributed to other potential environmental and health impacts including human and ecotoxicity, global warming potential, ozone depletion, and acidification. Average eutrophication potential can be reduced by about 70% when Level 2 (TN = 3 mg/L; TP = 0.1 mg/L) treatments are employed instead of Level 1 (TN = 8 mg/L; TP = 1 mg/L), but the implementation of more advanced tertiary processes for Level 3 (TN = 1 mg/L; TP = 0.01 mg/L) treatment may only lead to an additional 15% net reduction in life-cycle eutrophication potential.

    2012-08-01

    More than 2,000 drug courts in the United States provide supervision and substance-abuse treatment to thousands of offenders. Yet the treatment continuum from assessment to aftercare is underexplored. The effectiveness of the Level of Service Inventory-Revised (LSI-R) as a risk assessment tool is well established. However, fewer studies have considered its use in guiding treatment strategies. In using the LSI-R, the drug court program relied on the structured interview protocol (not the risk classification scores) to identify criminogenic needs that then helped determine placement in a high- or low-needs treatment track. To evaluate the effectiveness of these treatment placement decisions, this research used the LSI-R scores to examine individual and group differences (N = 182). Significant and substantive differences at the individual and group levels were found thus providing empirical support for using the LSI-R as a link between assessment and treatment. Implications for developing standards and practice protocols for drug courts are discussed.

    Life Cycle Assessment has been used to compare different scenarios involving wastewater reuse, with special focus on toxicity-related impact categories. The study is based on bench-scale experiments applying ozone and ozone in combination with hydrogen peroxide to a wastewater effluent from a Spanish sewage treatment plant. Two alternative characterisation models have been used to account for toxicity of chemical substances, namely USES-LCA and EDIP97. Four alternative scenarios have been assessed: wastewater discharge plus desalination supply, wastewater reuse without tertiary treatment, wastewater reuse after applying a tertiary treatment consisting on ozonation, and wastewater reuse after applying ozonation in combination with hydrogen peroxide. The results highlight the importance of including wastewater pollutants in LCA of wastewater systems assessing toxicity, since the contribution of wastewater pollutants to the overall toxicity scores in this case study can be above 90%. Key pollutants here are not only heavy metals and other priority pollutants, but also non-regulated pollutants such as pharmaceuticals and personal care products. Wastewater reuse after applying any of the tertiary treatments considered appears as the best choice from an ecotoxicity perspective. As for human toxicity, differences between scenarios are smaller, and taking into account the experimental and modelling uncertainty, the benefits of tertiary treatment are not so clear. From a global warming potential perspective, tertiary treatments involve a potential 85% reduction of greenhouse gas emissions when compared with desalination.

    Full Text Available Abstract Background Critical needs for treatment trials in gastroesophageal reflux disease (GERD include assessing response to treatment, evaluating symptom severity, and translation of symptom questionnaires into multiple languages. We evaluated the previously validated Reflux Disease Questionnaire (RDQ for internal consistency, reliability, responsiveness to change during treatment and the concordance between RDQ and specialty physician assessment of symptom severity, after translation into Swedish and Norwegian. Methods Performance of the RDQ after translation into Swedish and Norwegian was evaluated in 439 patients with presumed GERD in a randomized, double-blind trial of active treatment with a proton pump inhibitor. Results The responsiveness was excellent across three RDQ indicators. Mean change scores in patients on active treatment were large, also reflected in effect sizes that ranged from a low of 1.05 (dyspepsia to a high of 2.05 (heartburn and standardized response means 0.99 (dyspepsia and 1.52 (heartburn. A good positive correlation between physician severity ratings and RDQ scale scores was seen. The internal consistency reliability using alpha coefficients of the scales, regardless of language, ranged from 0.67 to 0.89. Conclusion The results provide strong evidence that the RDQ is amenable to translation and represents a viable instrument for assessing response to treatment, and symptom severity.

    In a companion paper, we established high levels of psychiatric morbidity in prisoners (Bebbington et al. Soc Psychiatry Psychiatr Epidemiol, 2016). In the current report, we evaluate how this morbidity translates into specific needs for treatment and the consequent implications for services. Mental health treatment needs and the extent to which they had been met were assessed in a representative sample of prisoners in a male and a female prison in London (Pentonville and Holloway). Prisoners were sampled at random in a sequential procedure based on the Local Inmate Data System. We targeted equal numbers of male remand, male sentenced, female remand, and female sentenced prisoners. Following structured assessment of psychosis, common mental disorders, PTSD, personality disorders and disorders of abuse, we used the MRC Needs for Care Assessment (NFCAS) to establish whether potential needs for care in ten areas of mental health functioning were met, unmet, or incapable of being met by services. Data on treatment experience were provided by 360 inmates. Eighty percent of females and 70% of males had at least one need for treatment. Over half (53.7%) of the needs of female prisoners were met, but only one third (36.5%) in males. Needs for medication were unmet in 32% of cases, while those for psychological treatment were unmet in 51%. Unmet needs for mental health treatment and care were common in the two prisons. This has adverse consequences both for individual prisoners and for the effective functioning of the criminal justice system.

    Full Text Available Abstract Background This needs assessment, initiated by the Academy for Healthcare Education Inc. in cooperation with AXDEV Group Inc., explored the knowledge, attitudes, behavior, and skills of community-based and academic-affiliated U.S. cardiologists in the area of CV risk assessment, treatment, and management from July 2006 to December 2006. Methods The needs assessment used a multistage, mixed-method approach to collect, analyze, and verify data from two independent sources. The exploratory phase collected data from a representative sampling of U.S. cardiologists by means of qualitative panel meetings, one-on-one interviews, and quantitative questionnaires. In the validation phase, 150 cardiologists from across the United States completed a quantitative online questionnaire. Data were analyzed with standardized statistical methods. Results The needs assessment found that cardiologists have areas of weakness pertaining to their interpersonal skills, which may influence patient-physician communication and patient adherence. Cardiologists appeared to have little familiarity with or lend little credence to the concept of relative CV risk. In daily clinical practice, they faced challenges with regard to optimal patient outcome in areas of patient referral from primary-care providers, CV risk assessment and treatment, and patient monitoring. Community-based and academic-affiliated cardiologists appeared to be only moderately interested in educational interventions that pertain to CV risk-reduction strategies. Conclusion Educational interventions that target cardiologists' interpersonal skills to enhance their efficacy may benefit community-based and academic-affiliated specialists. Other desirable educational initiatives should address gaps in the patient referral process, improve patient knowledge and understanding of their disease, and provide supportive educational tools and materials to enhance patient-physician communication.

    Adverse events during selective serotonin reuptake inhibitor (SSRI) treatment are frequent and may lead to premature treatment discontinuation. If attrition is associated with early worsening of side effects or the frequency, intensity, or burden of side effects, interventions to maximize retention could be focused on patients with these events. Outpatient participants (n=265) with nonpsychotic major depressive disorder entered an 8-week trial with an SSRI. At baseline and week 2, specific side effects were evaluated with the Systematic Assessment for Treatment Emergent Events – Systematic Inquiry, and at week 2 the Frequency, Intensity, and Burden of Side Effects Rating globally assessed side effects. Attrition was defined by those participants who left treatment after week 2 but before week 8. No specific week 2 side effect, either treatment emergent or with worsening intensity, was independently associated with attrition. Global ratings of side effect frequency, intensity, or burden at week 2 were also not associated with subsequent attrition. Neither global ratings nor specific side effects at week 2 were related to patient attrition during SSRI treatment. Other factors appear to contribute to patient decisions about continuing with treatment. PMID:20473060

    Full Text Available J Russell Ramsay Adult ADHD Treatment & Research Program, Perelman School of Medicine, University of Pennsylvania Philadelphia, PA, USA Abstract: Attention-deficit/hyperactivity disorder (ADHD is a neurodevelopmental syndrome that emerges in childhood or early adolescence and persists into adulthood for a majority of individuals. There are many other adults with ADHD who may not seek out evaluation and treatment until adulthood, having been able to “get by” before struggling with inattention, hyperactivity, and/or impulsivity in adulthood, in addition to facing the associated features of disorganization, poor time management, and procrastination among many others. A lifetime diagnosis of ADHD is associated with a wide range of life impairments, which makes a comprehensive and accurate diagnostic assessment essential in order to obtain appropriate treatment. Moreover, while there are effective medical and psychosocial treatments for ADHD, it is important to be able to track treatment response in order to evaluate whether adjustments in specific interventions are needed or referrals for adjunctive treatments and supports are indicated to facilitate optimal therapeutic outcomes. The goal of this article is to provide a clinically useful review of the various measures that practicing clinicians can use to aid in the diagnostic assessment and monitoring of psychosocial and medical treatment of ADHD in adult patients. This review includes various structured interviews, screening scales, adult ADHD symptom inventories, measures of associated features of ADHD, as well as ratings of impairment and functioning which can be adapted to clinicians’ practice needs in order to track treatment progress and optimize treatments for adults with ADHD.

    Liver compartment syndrome is a life-threatening complication of hepatic subcapsular hematoma; diagnosis and assessment of treatment effects are therefore important. We report a rare case of liver compartment syndrome due to spontaneous hepatic subcapsular hematoma without any underlying conditions, in which Doppler ultrasonography (US) proved useful in both diagnosis and assessment of treatment effects. A 32-year-old woman experienced sudden epigastralgia and was diagnosed with hepatic subcapsular hematoma in the right lobe, based on contrast-enhanced computed tomography. Hepatic arteriography showed active hemorrhage and Doppler US showed retrograde flow in the right portal vein. From these findings, we diagnosed hepatic subcapsular hematoma complicated with liver compartment syndrome, and performed embolization of the bleeding point and percutaneous hematoma drainage. After these medical procedures, normalized antegrade flow in the right portal vein was observed on Doppler US. No underlying conditions contributing to hematoma were identified. In this case, Doppler US was useful for both diagnosis and assessment of treatment effects in liver compartment syndrome. When we examine patients with hepatic subcapsular hematoma, Doppler US should be used to diagnose the presence of liver compartment syndrome and assess treatment effects.

    The information gathered in a centralized intake unit (CIU) allows payers and administrators to examine if there are access issues for their population. For this study, the authors examined whether there were gender differences in the rate at which people are admitted to treatment within 30 days of assessment. Of the 5,004 individuals seeking publicly-funded substance abuse treatment in Detroit for the years 1996-97, 50.3% of those assessed at the CIU actually entered treatment. Women (31% of the people assessed) had a lower rate of admission (45% for women versus 53% for men) a difference that was maintained even after controlling for known risk factors. Women who were given priority for admission (i.e., those who were pregnant, had children, or injected drugs) had a higher rate of admission than other women (73% versus 39%), but only 17% of the women presenting were included in the priority groups. Men who were injecting drugs (a priority group) also had a higher rate of admission than other men (83% versus 49%). In multivariate analysis controlling for priority groups and known risk factors, women were still less likely to be admitted to treatment within 30 days of admission than men. Establishing priorities improves the rate of admission within 30 days of assessment for those groups, but more needs to be done to improve the admission rate for women. These results demonstrate that a CIU allows administrators to monitor for access issues.

  2. Assessment and treatment of insomnia in adult patients with alcohol use disorders.

    Science.gov (United States)

    Brower, Kirk J

    2015-06-01

    Insomnia in patients with alcohol dependence has increasingly become a target of treatment due to its prevalence, persistence, and associations with relapse and suicidal thoughts, as well as randomized controlled studies demonstrating efficacy with behavior therapies and non-addictive medications. This article focuses on assessing and treating insomnia that persists despite 4 or more weeks of sobriety in alcohol-dependent adults. Selecting among the various options for treatment follows a comprehensive assessment of insomnia and its multifactorial causes. In addition to chronic, heavy alcohol consumption and its effects on sleep regulatory systems, contributing factors include premorbid insomnia; co-occurring medical, psychiatric, and other sleep disorders; use of other substances and medications; stress; environmental factors; and inadequate sleep hygiene. The assessment makes use of history, rating scales, and sleep diaries as well as physical, mental status, and laboratory examinations to rule out these factors. Polysomnography is indicated when another sleep disorder is suspected, such as sleep apnea or periodic limb movement disorder, or when insomnia is resistant to treatment. Sobriety remains a necessary, first-line treatment for insomnia, and most patients will have some improvement. If insomnia-specific treatment is needed, then brief behavioral therapies are the treatment of choice, because they have shown long-lasting benefit without worsening of drinking outcomes. Medications work faster, but they generally work only as long as they are taken. Melatonin agonists; sedating antidepressants, anticonvulsants, and antipsychotics; and benzodiazepine receptor agonists each have their benefits and risks, which must be weighed and monitored to optimize outcomes. Some relapse prevention medications may also have sleep-promoting activity. Although it is assumed that treatment for insomnia will help prevent relapse, this has not been firmly established. Therefore

    Environmental impacts of conventional and emerging perchlorate drinking water treatment technologies were assessed using life cycle assessment (LCA). Comparison of two ion exchange (IX) technologies (i.e., nonselective IX with periodic regeneration using brines and perchlorate-selective IX without regeneration) at an existing plant shows that brine is the dominant contributor for nonselective IX, which shows higher impact than perchlorate-selective IX. Resource consumption during the operational phase comprises >80% of the total impacts. Having identified consumables as the driving force behind environmental impacts, the relative environmental sustainability of IX, biological treatment, and catalytic reduction technologies are compared more generally using consumable inputs. The analysis indicates that the environmental impacts of heterotrophic biological treatment are 2-5 times more sensitive to influent conditions (i.e., nitrate/oxygen concentration) and are 3-14 times higher compared to IX. However, autotrophic biological treatment is most environmentally beneficial among all. Catalytic treatment using carbon-supported Re-Pd has a higher (ca. 4600 times) impact than others, but is within 0.9-30 times the impact of IX with a newly developed ligand-complexed Re-Pd catalyst formulation. This suggests catalytic reduction can be competitive with increased activity. Our assessment shows that while IX is an environmentally competitive, emerging technologies also show great promise from an environmental sustainability perspective.

    Waste disposal is an important part of the life cycle of a product and is associated with environmental burdens like any other life-cycle stages. In this study, an integrated assessment for solid waste treatment practices, especially household solid waste, was undertaken to evaluate the impact contribution of household solid waste treatment alternatives towards the sustainable development by using Life Cycle Inventory Assessment method. A case study has been investigated under various possible scenarios, such as (1) landfill without landfill gas recovery, (2) landfill with landfill gas recovery and flaring, (3) landfill with landfill gas recovery and electric generation, (4) composting, and (5) incineration. The evaluation utilized the Life Cycle Inventory Assessment method for multiple assessments based on various aspects, such as greenhouse gas emission/reduction, energy generation/consumption, economic benefit, investment and operating cost, and land use burden. The results showed that incineration was the most efficient alternative for greenhouse gas emission reduction, economic benefit, energy recovery, and land use reduction, although it was identified as the most expensive for investment and operating cost, while composting scenario was also an efficient alternative with quite economic benefit, low investment and operating cost, and high reduction of land use, although it was identified as existing greenhouse gas emission and no energy generation. Furthermore, the aim of this study was also to establish localized assessment methods that waste management agencies, environmental engineers, and environmental policy decision makers can use to quantify and compare the contribution to the impacts from different waste treatment options.

    This study aimed to assess the reliability of experienced Chinese orthodontists in evaluating treatment outcome and to determine the correlations between three diagnostic information sources. Sixty-nine experienced Chinese orthodontic specialists each evaluated the outcome of orthodontic treatment of 108 Chinese patients. Three different information sources: study casts (SC), lateral cephalometric X-ray images (LX) and facial photographs (PH) were generated at the end of treatment for 108 patients selected randomly from six orthodontic treatment centers throughout China. Six different assessments of treatment outcome were made by each orthodontist using data from the three information sources separately and in combination. Each assessment included both ranking and grading for each patient. The rankings of each of the 69 judges for the 108 patients were correlated with the rankings of each of the other judges yielding 13 873 Spearman rs values, ranging from -0.08 to +0.85. Of these, 90% were greater than 0.4, showing moderate-to-high consistency among the 69 orthodontists. In the combined evaluations, study casts were the most significant predictive component (R(2)=0.86, P<0.000 1), while the inclusion of lateral cephalometric films and facial photographs also contributed to a more comprehensive assessment (R(2)=0.96, P<0.000 1). Grading scores for SC+LX and SC+PH were highly significantly correlated with those for SC+LX+PH (r(SC+LX)vs.(SC+LX+PH)=0.96, r(SC+PH)vs.(SC+LX+PH)=0.97), showing that either SC+LX or SC+PH is an excellent substitute for all three combined assessment.

  10. Assessing and reporting heterogeneity in treatment effects in clinical trials: a proposal

    2010-08-01

    Full Text Available Abstract Mounting evidence suggests that there is frequently considerable variation in the risk of the outcome of interest in clinical trial populations. These differences in risk will often cause clinically important heterogeneity in treatment effects (HTE across the trial population, such that the balance between treatment risks and benefits may differ substantially between large identifiable patient subgroups; the "average" benefit observed in the summary result may even be non-representative of the treatment effect for a typical patient in the trial. Conventional subgroup analyses, which examine whether specific patient characteristics modify the effects of treatment, are usually unable to detect even large variations in treatment benefit (and harm across risk groups because they do not account for the fact that patients have multiple characteristics simultaneously that affect the likelihood of treatment benefit. Based upon recent evidence on optimal statistical approaches to assessing HTE, we propose a framework that prioritizes the analysis and reporting of multivariate risk-based HTE and suggests that other subgroup analyses should be explicitly labeled either as primary subgroup analyses (well-motivated by prior evidence and intended to produce clinically actionable results or secondary (exploratory subgroup analyses (performed to inform future research. A standardized and transparent approach to HTE assessment and reporting could substantially improve clinical trial utility and interpretability.

    2012-04-01

    Fungal biomass has the ability to decolorize a wide variety of dyes successfully through a number of mechanisms. A brown rot isolate, previously identified as Aspergillus sp. EL-2, was used in the aerobic treatment of textile waste water efficiently. In the current work, the treated waste water was tested chemically using more than one combined treatment. Microbial toxicity, phytotoxicity, genotoxicity and cytotoxicity were also studied to assess the toxicity level for each treatment. The obtained data suggest that the contribution of more than one mode of treatment is essential to ensure complete destruction of the by-products. The use of gamma irradiation (25 kGy) after the bioremediation step led to the decrease of the by-products of biodegradation as observed by visible spectrum and Fourier transfer infra red spectroscopy (FT-IR). The toxicity assessment presented variable results indicating the need for more than one toxicity test to confirm the presence or absence of hazardous compounds. Brown rot fungus could be used efficiently in the treatment of textile waste water without the risk of obtaining high carcinogenic or genotoxic compounds, especially if combined treatment is employed.

    This study examines wastes associated with the onshore exploration and production of crude oil and natural gas in the US. The objective of this study was to update and enhance the current state of knowledge with regard to oil and gas waste quantities, the potential environmental impact of these wastes, potential methods of treatment, and the costs associated with meeting various degrees of treatment. To meet this objective, the study consisted of three tasks: (1) the development of a production Environmental Database (PED) for the purpose of assessing current oil and gas waste volumes by state and for investigating the potential environmental impacts associated with current waste disposal practices on a local scale; (2) the evaluation of available and developing technologies for treating produced water waste streams and the identification of unit process configurations; and (3) the evaluation of the costs associated with various degrees of treatment achievable by different treatment configurations. The evaluation of feasible technologies for the treatment of produced water waste streams was handled in the context of comparing the level of treatment achievable with the associated cost of treatment. Treatment processes were evaluated for the removal of four categories of produced water contaminants: particulate material, volatile organic compounds, adsorbable organic compounds, and dissolved inorganic species. Results showed dissolved inorganic species to be the most costly to remove. The potential cost of treating all 18.3 billion barrels of produced water generated in a year amounts to some 15 billion dollars annually.

    Objective Given the considerable disagreement between the Peer Assessment Rating (PAR) index and the American Board of Orthodontics Cast-Radiograph Evaluation, we aimed to develop a novel assessment system―the Improvement and Completion of Outcome (ICO) index―to evaluate the outcome of orthodontic treatment. Methods Sixteen criteria from 4 major categories were established to represent the pretreatment malocclusion status, as well as the degree of improvement and level of completion of outcome during/after treatment: dental relationship (arch length discrepancy, irregularity, U1-SN, and IMPA); anteroposterior relationship (overjet, right and left molar position, ANB); vertical relationship (anterior overbite, anterior open-bite, lateral open-bite, SN-MP); and transverse relationship (dental midline discrepancy, chin point deviation, posterior cross-bite, occlusal plane cant). The score for each criterion was defined from 0 or −1 (worst) to 5 (ideal value or normal occlusion) in gradations of 1. The sum of the scores in each category indicates the area and extent of the problems. Improvement and completion percentages were estimated based on the pre- and post-treatment total scores and the maximum total score. If the completion percentage exceeded 80%, treatment outcome was considered successful. Results Two cases, Class I malocclusion and skeletal Class III malocclusion, are presented to represent the assessment procedure using the ICO index. The difference in the level of improvement and completion of treatment outcome can be clearly explained by using 2 percentage values. Conclusions Thus, the ICO index enables the evaluation of the quality of orthodontic treatment objectively and consecutively throughout the entire treatment process. PMID:27478797

    White spot lesions (WSLs) are common adverse effect of orthodontic treatment, which can be prevented and treated by orthodontists. This study was conducted to assess Iranian orthodontists' practice regarding the prevention and treatment of WSLs in their patients. In this cross-sectional study, 109 Iranian orthodontists were selected from the Iranian Association of Orthodontists' directory by cluster sampling. For data collection, a questionnaire was designed and its validity and reliability was confirmed (Cronbach's α =0.85). The questionnaire included eight general questions and eight questions about practice with regard to the prevention and treatment of WSL. Data were analyzed by descriptive tests, ANOVA test, and t-test in SPSS 20 software. P plan educational courses which are useful for promoting their knowledge and practice about new products and procedures used for the prevention and treatment of WSLs.

    Nutrition is an important determinant of health in persons over the age of 65. Malnutrition in the elderly is often underdiagnosed. Careful nutritional assessment is necessary for both the successful diagnosis and development of comprehensive treatment plans for malnutrition in this population. The purpose of this article is to provide clinicians with an educational overview of this essential but often underecognized aspect of geriatric assessment. This article will review some common issues in nutrition for the elderly in both hospital and community settings. The complexity and impact of multiple comorbidities on the successful nutritional assessment of elderly patients is highlighted by using case scenarios to discuss nutritional issues common to elderly patients and nutritional assessment tools. Three case studies provide some context for an overview of these issues, which include the physiology of aging, weight loss, protein undernutrition, impaired cognition, malnutrition during hospitalization, screening procedures, and general dietary recommendations for patients 65 years of age and older.

    Sustainability has strong implications on the practice of engineering. Life cycle assessment (LCA) is an appropriate methodology for assessing the sustainability of a wastewater treatment plant design. The present study used a LCA approach for comparing alternative wastewater treatment processes for small and decentralised rural communities. The assessment was focused on two energy-saving systems (constructed wetland and slow rate infiltration) and a conventional one (activated sludge process). The low environmental impact of the energy-saving wastewater treatment plants was demonstrated, the most relevant being the global warming indicator. Options for reduction of life cycle impacts were assessed including materials used in construction and operational lifetime of the systems. A 10% extension of operation lifetime of constructed wetland and slow rate infiltration systems led to a 1% decrease in CO2 emissions, in both systems. The decrease in the abiotic depletion was 5 and 7%, respectively. Also, replacing steel with HDPE in the activated sludge tank resulted in a 1% reduction in CO2 emission and 1% in the abiotic depletion indicator. In the case of the Imhoff tank a 1% reduction in CO2 emissions and 5% in the abiotic depletion indicator were observed when concrete was replaced by HDPE.

    Full Text Available Management  of  patients  with  rotator  cuff  myofascial  pain syndrome varies  and  successful  intervention  is  dependent  on accurate assessment. The aim of this case report is to show the importance of accurate assessment  and  clinical  reasoning  in  the  physiotherapeutic management  of a  patient  suffering  from  ante-cubital  and  anterior shoulder  pain.  The  patient was  referred  for  physiotherapy  after proving refractory  to  treatment  with  non-steroidal anti-inflammatory medication. The physiotherapist diagnosed a rotator cuff myofascial pain syndrome and treatment proceeded on that basis. Treatment consisted of twitch-obtaining dry needling, myofascial release and exercise therapy.  The result was a change in the harryman rotator cuff functional Assessment Scale score from 22/52 to 43/52 over eight treatments. Strength was regained and subjective pain report on the visual rating scale was improved to 1/10. The case study highlights the importance of accurate assessment and consideration of alternative myofascial sources for pain even in circumstances which initially seem trauma related. Precise diagnosis of the cause - in this case rotator cuff myofascial pain syndrome – will result in effective treatment being administered.

    Although various laboratory tests have been studied with an intended use in the diagnosis of pelvic inflammatory disease (PID) and the assessment of treatment response, the neutrophil/lymphocyte ratio (NLR) has not been investigated in PID. We aimed to explore the value of blood NLR in diagnosis of PID and assessment of the treatment response. Sixty-five patients followed-up and treated with the diagnosis of PID in Izmir Tepecik Training and Research Hospital were retrospectively reviewed. The NLR measured before treatment and after clinical remission in the patients diagnosed with PID were assessed and compared with controls (N.=65). In the patient group, the NLR measured before treatment was statistically significantly higher than the NLR measured after clinical remission (6.9±6.4 vs. 2.03±0.8, P<0.001). Similarly, comparison of the NLR measured in the patient group before treatment with the control group showed that this ratio was statistically significantly higher in the patient group before treatment (6.9±6.4 vs. 1.9±0.5, P<0.001). A comparison of the NLR measured after clinical remission did not reveal a statistically significant difference when compared with control group (1.9±0.5 vs. 2.03±0.8, P=0.981). The NLR increases in patients diagnosed with PID and returns to normal levels when the patients enter clinical remission. Since there is currently no laboratory test available that indicates clinical improvement by returning to normal levels, as achieved by the NLR, and since it is an inexpensive and easy-to-apply test, we suggest that the NLR can be conveniently used to show clinical improvement in PID.

    Full Text Available The magnitude of treatment effect can be assessed by a number of methods. One method of collectively analysing data is that used by the Cochrane Collaboration. Their systematic reviews identify, analyse and present research-based evidence in an accessible format. These reviews may contain meta-analyses combining data from multiple studies to provide robust evaluations of overall treatment effects. In 2003, Cochrane reviews of data for treatment with corticosteroids in idiopathic pulmonary fibrosis (IPF found no evidence supporting their use; similarly, reviews of immunomodulatory agents found very little evidence to support their use. A recent update of these Cochrane reviews failed to identify any evidence supporting the use of corticosteroids in IPF; however, a review of non-steroid agents in the treatment of IPF identified 15 clinical trials suitable for analysis. Two trials of interferon-γ-1b were combined, and no treatment effect was observed in terms of survival. Two Japanese trials of treatment with pirfenidone were combined, and a positive effect of pirfenidone on pulmonary function decline was observed. Meta-analysis of three phase III studies suggested that pirfenidone significantly increased progression-free survival by 30%. The findings of this systematic review, although not presenting new original data, together with an acceptable safety profile, suggest that pirfenidone may have a role in IPF treatment.

  20. Identification and assessment of site treatment plan implementation opportunities for emerging technologies

    The Department of Energy (DOE), in response to the 1992 Federal Facility Compliance Act, has prepared Site Treatment Plans (STP) for the approximately 2,000 waste streams identified within its mixed waste inventory Concurrently, emerging mixed waste treatment technologies are in final development. This paper defines a three-phase process to identify and assess implementation opportunities for these emerging technologies within the STP. It highlights the first phase, functional matching of expected treatment capabilities with proposed treatment requirements. Matches are based on treatment type, regulated contaminant and waste matrix type, for both capabilities and requirements. Results identify specific waste streams and volumes that could be treated by each emerging technology. A study for Plasma Hearth Process, Delphi DETOX{sup sm}, Supercritical Water Oxidation and Vitrification shows that about 200,000 ml of DOE`s mixed waste inventory can potentially be treated by one or more of these emerging technologies. Actual implementations are small fractions of the treatable inventory. Differences between potential and actual implementations must be minimized to accrue optimum benefit from implementation of emerging or alternative treatment technologies. Functional matching is the first phase in identifying and quantifying benefits, addressing technology system and treatment issues, and providing, in part, the basis for STP implementation decisions. DOE, through EM`s Office of Technology Development, has funded this work.

  1. Quantitative MR imaging in planning and assessing novel cancer treatments Radiotherapy

    2001-01-01

    Novel treatments in cancer, like conformal radiotherapy and anticancer drugs, require new MRI techniques to assess their benefits and potential. In conformal radiotherapy, MRI can be used to measure the shape and dose of the conformed radiation field in dose sensitive gel test-objects thus validating the predicted dose computed by complex programs. In antiangiogenic drug treatment, the vascular dysfunction of the tumour can be assessed by MRI prior to treatment. Response to treatment may also be monitored by measuring the changes in vascular function. In this thesis, MRI of polyacrylamide gels is investigated as a 3D dosimeter for conformal radiotherapy treatment planning. Quantitative MRI sequences capable of measuring the wide range of T2 values typically expected in gel dosimetry, are identified. Different T2 measurement methods are compared in terms of accuracy, signal to noise ratio and acquisition time. Examples of a complex dose distribution in 2D and 3D are presented and compared to the planned dose p...

  2. Comparative study of municipal solid waste treatment technologies using life cycle assessment method

    The aim of the study is to analyze three different waste treatment technologies by life cycle assessment tool. Sanitary landfill, incineration and gasification-pyrolysis of the waste treatment technologies are studied in SimaPro software based on input-output materials flow. SimaPro software has been applied for analyzing environmental burden by different impact categories. All technologies are favorable to abiotic and ozone layer depletion due to energy recovery from the waste treatment facilities. Sanitary landfill has the significantly lower environmental impact among other thermal treatment while gases are used for fuel with control emission environment. However, sanitary landfill has significant impact on photochemical oxidation, global warming and acidification. Among thermal technology, pyrolysis-gasification is comparatively more favorable to environment than incineration in global warming, acidification, eutrophication and eco-toxicity categories. Landfill with energy recovery facilities is environmentally favorable. However, due to large land requirement, difficult emission control system and long time span, restriction on land filling is applying more in the developed countries. Pyrolysis-gasification is more environmental friendly technology than incineration due to higher energy recovery efficiency. Life cycle assessment is an effective tool to analyze waste treatment technology based on environmental performances.

    We aimed to assess the relationship between cytokine levels and the severity of the manic period in medication free patients. 30 Medication free patients and 28 healthy subjects (HS) were recruited. Plasma levels of pro-inflammatory, anti-inflammatory, inflammatory cytokines, and hs-CRP levels were investigated upon hospital admission, after six weeks follow up in bipolar disease manic episode and the results were compared to HS. The severity of the manic episodes was assessed according to the Young mania rating scale. TNF-α, INF-γ, IL-6 and hs-CRP levels were significantly higher in patients with manic episode of bipolar I disorder before treatment than HS. After treatment the levels of TNF-α, INF-γ, IL-6 and hs-CRP were observed to be significantly decreased. There was no difference between the levels of anti-inflammatory cytokines in patients before or after treatment of bipolar disorder and HS. hs-CRP was observed to be the only parameter correlated with clinical response. The most significant outcome of this study is the correlation between clinical outcome and hs-CRP levels in treatment naive manic episode bipolar type I patients. hs-CRP is the most consistent indicator according to pro-inflammatory, inflammatory and anti-inflammatory cytokines, in predicting treatment outcomes.

    Assessment of treatment outcome is the only non-invasive approach to identify the effects of cleft lip and palate repair and modify management accordingly. Here the aim is to assess the outcome of complete unilateral cleft lip and palate (CUCLP) patients using EUROCRAN index and to check whether there are any factors associated with the treatment outcome. It is a retrospective cross sectional study. Dental models were collected from archives of two cleft referral centers in Pakistan. Five blinded examiners scored 101 models twice at two week interval. The primary outcome was mean EUROCRAN scores based on dental arch relationships and palatal surface morphology. A mean(SD) score of 2.72 (0.76) and 2.20 (0.73) was determined based on dental arch relationships and palatal surface morphology, respectively. According to the final logistic regression model, modified Millard technique (cheiloplasty) and Veau-Wardill-Kilners' method (palatoplasty) had higher odds of producing unfavorable treatment outcome. Present study determined a fair and a fair to poor treatment outcome based on dental arch relationships and palatal surface morphology, respectively. Our study suggests a significant association between treatment outcome and primary surgical techniques for lip and palate. These findings could warrant a modification of management protocols to ensure improvement in future cleft outcomes. Copyright © 2017 Elsevier B.V. All rights reserved.

    Using multidimensional scaling (MDS) analysis, this study examined how patient conceptualisations of treatment motivation compare with theoretically based assumptions used in current assessment approaches. Patients undergoing antiretroviral therapy for HIV/AIDS (n=39) rated for similarity between all possible pairings of 23 treatment descriptions, including descriptors of intrinsic, extrinsic, approach and avoidance motivation. MDS analyses revealed that patient perceptions of intrinsic and extrinsic motivations often differ from those based on definitions derived from common interpretations of self-determination theory. Findings also showed that patients reported motivation for avoiding treatment when they associated their medication regimens with side effects and other negatively valenced outcomes. The study describes new applications of MDS in assessing how patients perceive the relationship between treatment behaviours and specific forms of motivation, such as intrinsic and extrinsic motivations. In addition, the study suggests how MDS may be used to develop behavioural strategies aimed at helping patients follow their regimens consistently by identifying treatment conceptualisations and contexts that facilitate or impede adherence.

    The "Pawspice" philosophy, which the author introduced at the 2000 American Veterinary Medical Association meeting, focuses on symptom management along with a kinder, gentler, or modified approach to standard therapy. Many veterinarians have preconceived bias or ingrained beliefs about aging, serious illness, multiple comorbidities, and cancer, which may cause a negative or dismissive approach toward palliative treatment, especially in geriatric pets. Veterinarians and their v-teams must overcome this insensitive attitude about life-limiting disease. This article describes assessment, treatment, and home management of some nonpainful life-limiting diseases, including cancer and age-related decline of vital functions in the Pawspice setting. 2011.

    Full Text Available BACKGROUND: There is an urgent need to substitute the highly toxic compounds still in use for treatment of the encephalitic stage of human African trypanosomiasis (HAT. We here assessed the treatment with the doublet cordycepin and the deaminase inhibitor deoxycoformycin for this stage of infection with Trypanosoma brucei (T.b.. METHODOLOGY/PRINCIPAL FINDINGS: Cordycepin was selected as the most efficient drug from a direct parasite viability screening of a compound library of nucleoside analogues. The minimal number of doses and concentrations of the drugs effective for treatment of T.b. brucei infections in mice were determined. Oral, intraperitoneal or subcutaneous administrations of the compounds were successful for treatment. The doublet was effective for treatment of late stage experimental infections with human pathogenic T.b. rhodesiense and T.b. gambiense isolates. Late stage infection treatment diminished the levels of inflammatory cytokines in brains of infected mice. Incubation with cordycepin resulted in programmed cell death followed by secondary necrosis of the parasites. T.b. brucei strains developed resistance to cordycepin after culture with increasing concentrations of the compound. However, cordycepin-resistant parasites showed diminished virulence and were not cross-resistant to other drugs used for treatment of HAT, i.e. pentamidine, suramin and melarsoprol. Although resistant parasites were mutated in the gene coding for P2 nucleoside adenosine transporter, P2 knockout trypanosomes showed no altered resistance to cordycepin, indicating that absence of the P2 transporter is not sufficient to render the trypanosomes resistant to the drug. CONCLUSIONS/SIGNIFICANCE: Altogether, our data strongly support testing of treatment with a combination of cordycepin and deoxycoformycin as an alternative for treatment of second-stage and/or melarsoprol-resistant HAT.

    To update the reader's knowledge about the factors that influence bone mineral accrual and to review the advances in the assessment of bone health and treatment of bone disorders. Maternal vitamin D status influences neonatal calcium levels, bone mineral density (BMD) and bone size. In turn, BMD z-score tends to track in childhood. These factors highlight the importance of bone health as early as fetal life. Dual-energy x-ray absorptiometry is the mainstay of clinical bone health assessment in this population because of the availability of appropriate reference data. Recently, more information has become available about the assessment and treatment of bone disease in chronically ill pediatric patients. Bone health must become a health focus starting prenatally in order to maximize peak bone mass and to prevent osteoporosis-related bone disease in adulthood. Vitamin D, calcium and weight-bearing activity are the factors of key importance throughout childhood in achieving optimal bone health as BMD z-score tracks through childhood and into adulthood. Recent updates of the International Society for Clinical Densitometry focus on the appropriate use of dual-energy x-ray absorptiometry in children of all ages, including children with chronic disease, and on the treatment of pediatric bone disease.

  12. Attenuation of treatment effect due to measurement variability in assessment of progression-free survival.

    2012-01-01

    For normally distributed data analyzed with linear models, it is well known that measurement error on an independent variable leads to attenuation of the effect of the independent variable on the dependent variable. However, for time-to-event variables such as progression-free survival (PFS), the effect of the measurement variability in the underlying measurements defining the event is less well understood. We conducted a simulation study to evaluate the impact of measurement variability in tumor assessment on the treatment effect hazard ratio for PFS and on the median PFS time, for different tumor assessment frequencies. Our results show that scan measurement variability can cause attenuation of the treatment effect (i.e. the hazard ratio is closer to one) and that the extent of attenuation may be increased with more frequent scan assessments. This attenuation leads to inflation of the type II error. Therefore, scan measurement variability should be minimized as far as possible in order to reveal a treatment effect that is closest to the truth. In disease settings where the measurement variability is shown to be large, consideration may be given to inflating the sample size of the study to maintain statistical power.

  13. Framework for feasibility assessment and performance analysis of riverbank filtration systems for water treatment

    2012-03-01

    Bank filtration (BF) is an attractive, robust and reliable water treatment technology. It has been used in Europe and USA for a long time; however experience with this technology so far is site specific. There are no guidelines or tools for transfer of this technology to other locations, specifically to developing countries. A four-step methodology was developed at UNESCO-IHE to analyse feasibility and to predict the performance of BF for water treatment. This included (i) hydraulic simulation using MODFLOW; (ii) determination of share of bank filtrate using NASRI BF simulator; (iii) prediction of water quality from a BF system using the water quality guidelines developed and (iv) comparison of the costs of BF systems and existing conventional surface water treatment systems for water treatment. The methodology was then applied to assess feasibility of BF in five cities in Africa. It was found that in most of the cities studied BF is a feasible and attractive option from hydraulic, water quality as well as operational cost considerations. Considerable operational and maintenance costs saving can be achieved and water quality can be further improved by switching from conventional chemical-based surface water treatment to BF or at least by replacing some of the treatment units with BF systems. © IWA Publishing 2012.

    2011-01-01

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

    2017-09-06

    The management of municipal solid waste (MSW) is one of the main costs incurred by local authorities in developing countries. According to some estimates, these costs can account for up to 50% of city government budgets. It is therefore of importance that policymakers, urban planners and practitioners have an adequate understanding of what these costs consist of, from collection to final waste disposal. This article focuses on a specific stage of the MSW value chain, the treatment of waste, and it aims to identify cost patterns associated with the implementation and operation of waste treatment approaches in developing Asian countries. An analysis of the capital (CAPEX) and operational expenditures (OPEX) of a number of facilities located in countries of the region was conducted based on a database gathering nearly 100 projects and which served as basis for assessing four technology categories: composting, anaerobic digestion (AD), thermal treatment, and the production of refuse-derived fuel (RDF). Among these, it was found that the least costly to invest, asa function of the capacity to process waste, are composting facilities, with an average CAPEX per ton of 21,493 USD2015/ton. Conversely, at the upper end featured incineration plants, with an average CAPEX of 81,880 USD2015/ton, with this treatment approach ranking by and large as the most capital intensive of the four categories assessed. OPEX figures of the plants, normalized and analyzed in the form of OPEX/ton, were also found to be higher for incineration than for biological treatment methods, although on this component differences amongst the technology groups were less pronounced than those observed for CAPEX. While the results indicated the existence of distinct cost implications for available treatment approaches in the developing Asian context, the analysis also underscored the importance of understanding the local context asa means to properly identify the cost structure of each specific plant

    Distribution, penetration depth and amount of new mineralogical phases formed after the interaction between an inorganic treatment and a matrix are key factors for the evaluation of the conservation treatment behaviour. Nowadays, the conventional analytical methodologies, such as vibrational spectroscopies, scanning electron microscopy and X-ray diffraction, provide only qualitative and spot information. Here, we report, for the first time, the proof of concept of a methodology based on neutron imaging able to achieve quantitative data useful to assess the formation of calcium oxalate in a porous carbonatic stone treated with ammonium oxalate. Starting from the neutron attenuation coefficient of Noto stone-treated specimens, the concentrations of newly formed calcium oxalate and the diffusion coefficient have been calculated for both sound and decayed substrates. These outcomes have been also used for a comparative study between different treatment modalities.

    Full Text Available Introduction. Heart failure (HF is a common and potentially fatal condition. Cardiovascular research has focused on medical therapy for HF. Theoretical modelling could enable simulation and evaluation of the effectiveness of medications. Furthermore, the models could also help predict patients’ cardiac response to the treatment which will be valuable for clinical decision-making. Methods. This study presents a fast parameters estimation algorithm for constructing a cardiovascular model for medicine evaluation. The outcome of HF treatment is assessed by hemodynamic parameters and a comprehensive index furnished by the model. Angiotensin-converting enzyme inhibitors (ACEIs were used as a model drug in this study. Results. Our simulation results showed different treatment responses to enalapril and lisinopril, which are both ACEI drugs. A dose-effect was also observed in the model simulation. Conclusions. Our results agreed well with the findings from clinical trials and previous literature, suggesting the validity of the model.

    Multiple sclerosis (MS) is a major inflammatory and demyelinating disease of the central nervous system. Although a significant incidence and prevalence of psychological disorders in MS has been reported there is limited data on the prevalence of personality disorders (PD) in these patients. Recent findings indicate the need for early diagnosis and treatment of PD in MS patients in the interests of prognosis, conformity to treatment and patient's quality of life improvement. This article summarizes existing evidence on prevalence, types and diagnostic criteria of PD in MS, clinical manifestations of personality pathology or changes in MS patients, and instruments currently used for diagnosis and assessment of PD in this group of patients. Underlying mechanisms suggested as causes of personality changes in MS patients are also discussed. The article reviews therapeutic strategies, including pharmacotherapy and psychotherapy interventions and emphasizes the need for a multidisciplinary approach to patient's treatment.

    To investigate whether plain radiography is useful for assessing the changes in gouty tophi size following hypouricemic therapy. Gout was diagnosed according to the American College of Rheumatology criteria. Before and after hypouricemic treatment, serum uric acid level was measured, and plain radiography was performed to measure gouty tophi size. The tophi were graded by measuring the maximum vertical and horizontal diameters, and they were scored by adding up the scores of the grades. The vertical diameter was measured on both sides of the proximal phalanges (PPs). The horizontal diameter was measured on the lateral side of the PPs. The maximum vertical diameter measurement was graded 0-4. The maximum horizontal diameter measurement was graded 0-3. Seven hundred first metatarsal phalangeal joints (MTPJ) of 350 patients with gout were assessed for gouty tophi. Tophi were observed using plain radiography in 174 MTPJs (24.9%) of 109 patients (31.1%). Follow-up plain radiography was performed in 60 of these patients. Before the treatment, the average serum uric acid level of these patients was 8.3 ± 1.9 mg/dL, and the average tophi score was 3.7 ± 2.5. After hypouricemic treatment, the uric acid level decreased to 5.9 ± 1.6 mg/dL (P treatment. © 2016 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

    Full Text Available INTRODUCTION: Motivation is deemed a critical component for interventions intended to change behaviors related to the use of alcohol and other drugs. The classification of patients in 'stages of change' can be a useful tool for the organization and improvement of treating programs. METHODS: This study assessed the stages of change using the scales URICA and SOCRATES in patients who attended two different treating programs for alcohol dependence in a specialized medical service. We performed an analysis of the association between stages of change and demographic aspects. After three months of treatment, patients were reassessed to evaluate their outcome. RESULTS: In the assessments using URICA, there was an association between stages of change and monthly income and age. There was no evidence that patients move across the stages of change. Using the scale SOCRATES, we found an association between stages of change and monthly income. In the reassessment, there was a significant movement across the stages of change. CONCLUSION: Patients who attend two different treating programs may have different motivation profiles. There was no movement congruent with the stage of change model, suggesting that patients may need more than 3 months to obtain significant changes in their motivation.

    Full Text Available Rasmussen's encephalitis is characterized by refractory epilepsy, neurological deterioration and progressive atrophy of one cerebral hemisphere. The objective of this study is to describe the importance of neuropsychological evaluation in the treatment decision and follow-up of patients with Rasmussen´s encephalitis. Neuropsychological assessment was performed in two steps. Firstly, the clinical history was obtained and the Vineland adaptative behavior scale (VABS was applied. After this first step, the patients with social maturity level equal or higher than the inferior limit underwent a battery of neuropsychological assessment. We evaluated three patients before any specific treatment was started, and six months after the intervention (surgery or plasmapheresis. Patient 1 underwent left hemispherectomy and had global improvement on second neuropsychological assessment. This suggests that the decision of performing surgery was adequate. Patients 2 and 3 underwent plasmapheresis. They did not present cognitive decline between both evaluations which suggest that our decision of postponing surgery was adequate as well. We conclude that neuropsychological assessment is important when evaluating patients with Rasmussen´s encephalitis. That is especially true for patients in whom disease progression is slow, and surgery timing has to be carefully planned.

    A questionnaire (Migraine Questionnaire; MQ) was developed to help pharmacists identify consumers with migraine suitable for non-prescription treatment with a triptan. Adults, who knew or thought that they had migraine, participated in three, sequential, community-based studies to validate the MQ. Overall, 1,353 subjects completed independent assessments with a pharmacist and a clinician (reference standard). The accuracy of the pharmacist assessment of suitability for a triptan was compared with the clinician assessment. Clinicians using their standard practice determined that triptan therapy was suitable in 76.8% of cases compared with 48.8% for pharmacists using the MQ. The lack of concordance between pharmacists and clinicians in the false-positive cases (n = 113 of 660 subjects considered suitable for triptan by the pharmacists) usually related to headache diagnosis (57.5%), not safety aspects. The MQ is an effective tool for pharmacists to guide appropriate recommendation of a non-prescription triptan for migraine.

    2012-01-01

    Musculoskeletal conditions of the foot and ankle are an important public health challenge due to their increasing incidence combined with their substantial negative impact on patients’ quality of life. Non-pharmacological treatments serve as the first line of treatment and are frequently used for patients with musculoskeletal conditions of the foot and ankle. This review provides a summary of the assessments and non-invasive treatment options based upon available evidence. Recent studies show that individuals with foot and ankle pain have multiple co-existing impairments in alignment, motion, load distribution and muscle performance that may be evident in static and/or dynamic tasks. Additionally, both clinical and epidemiological studies support the inter-dependence between the foot and proximal joints. For instance, aberrant foot structure has been linked to foot osteoarthritis (OA), as well as OA and pain at the knee and hip. Most recently, advances in motion capture technology and plantar load distribution measurement offer opportunities for precise dynamic assessments of the foot and ankle. In individuals with musculoskeletal conditions of the foot and ankle, the chief objectives of treatment are to afford pain relief, restore mechanics (alignment, motion and/or load distribution) and return the patient to their desired level of activity participation. Given that most patients present with multiple impairments, combinational therapies that target foot-specific as well as global impairments have shown promising results. In particular, in individuals with rheumatoid arthritis and other rheumatic diseases, comprehensive rehabilitation strategies including early detection, foot-based interventions (such as orthoses) and wellness-based approaches for physical activity and self-management have been successful. While significant improvements have been made in the last decade to the assessment and treatment of foot and ankle conditions, few randomized clinical

    Rheumatoid arthritis (RA) affects millions world-wide. While anti-TNF treatment is widely used to reduce disease progression, treatment fails in ∼one-third of patients. No biomarker currently exists that identifies non-responders before treatment. A rigorous community-based assessment of the utility of SNP data for predicting anti-TNF treatment efficacy in RA patients was performed in the context of a DREAM Challenge (http://www.synapse.org/RA_Challenge). An open challenge framework enabled the comparative evaluation of predictions developed by 73 research groups using the most comprehensive available data and covering a wide range of state-of-the-art modelling methodologies. Despite a significant genetic heritability estimate of treatment non-response trait (h2=0.18, P value=0.02), no significant genetic contribution to prediction accuracy is observed. Results formally confirm the expectations of the rheumatology community that SNP information does not significantly improve predictive performance relative to standard clinical traits, thereby justifying a refocusing of future efforts on collection of other data.

    2012-12-01

    Spinal cord biologically effective dose (BED) limits are critical to safe spine stereotactic body radiotherapy (SBRT) delivery. In particular, when repeating SBRT to the same site, the problem of adding non-uniform BED distributions within small volumes of spinal cord has yet to be solved. We report a probability-based generalized BED (gBED) model to guide repeat spine SBRT treatment planning. The gBED was formulated by considering the sequential damaging probabilities of repeat spine SBRT treatments. Parameters from the standard linear-quadratic model, such as α/β = 2 Gy for the spinal cord, were applied. We tested the model based on SBRT specific spinal cord tolerance using a simulated and ten clinical repeat SBRT cases. The gBED provides a consistent solution for superimposing non-uniform dose distributions from different fractionation schemes, analogous to the BED for uniform dose distributions. Based on ten clinical cases, the gBED was observed to eliminate discrepancies in the cumulative BED of approximately 5% to 20% within small volumes (e.g. 0.1-2.0 cc) of spinal cord, as compared to a conventional calculation method. When assessing spinal cord tolerance for repeat spinal SBRT treatments, caution should be exercised when applying conventional BED calculations for small volumes of spinal cord irradiated, and the gBED potentially provides more conservative and consistently derived dose surrogates to guide safe treatment planning and treatment outcome modeling.

  15. CBCT in orthodontics: assessment of treatment outcomes and indications for its use.

    Kapila, S D; Nervina, J M

    2015-01-01

    Since its introduction into dentistry in 1998, CBCT has become increasingly utilized for orthodontic diagnosis, treatment planning and research. The utilization of CBCT for these purposes has been facilitated by the relative advantages of three-dimensional (3D) over two-dimensional radiography. Despite many suggested indications of CBCT, scientific evidence that its utilization improves diagnosis and treatment plans or outcomes has only recently begun to emerge for some of these applications. This article provides a comprehensive and current review of key studies on the applications of CBCT in orthodontic therapy and for research to decipher treatment outcomes and 3D craniofacial anatomy. The current diagnostic and treatment planning indications for CBCT include impacted teeth, cleft lip and palate and skeletal discrepancies requiring surgical intervention. The use of CBCT in these and other situations such as root resorption, supernumerary teeth, temporomandibular joint (TMJ) pathology, asymmetries and alveolar boundary conditions should be justified on the basis of the merits relative to risks of imaging. CBCT has also been used to assess 3D craniofacial anatomy in health and disease and of treatment outcomes including that of root morphology and angulation; alveolar boundary conditions; maxillary transverse dimensions and maxillary expansion; airway morphology, vertical malocclusion and obstructive sleep apnoea; TMJ morphology and pathology contributing to malocclusion; and temporary anchorage devices. Finally, this article utilizes findings of these studies and current voids in knowledge to provide ideas for future research that could be beneficial for further optimizing the use of CBCT in research and the clinical practice of orthodontics.

    2005-12-01

    As with members of other cultural and religious groups, patients within the Orthodox Jewish community present with their own distinct clinical psychiatric issues related to their unique beliefs and practices. This article reviews the existing literature and anecdotal experience on the psychopharmacologic assessment and treatment of Orthodox Jewish patients. Specific aspects examined include this group's perceived intense stigma in receiving treatment, the priority this community places on cognitive functioning, and how the influence of Jewish laws on marriage and sexual practices impacts one's treatment decisions. The relevance of Jewish dietary laws, the Sabbath, and the community's interest in alternative treatments are also discussed. The limited ethno-psychopharmacology research related to Orthodox Jewish psychiatric patients is reviewed. We conclude that understanding issues such as these is critical if one is going to work within this cultural system in order to successfully address their mental health issues. However, the dearth of controlled research in this community needs to be addressed to provide more effective treatment.

    A battery of in vitro bioassays, including a Neutral Red (NR) assay using MCF-7 cells for predicting cytotoxic chemicals, an ethoxy resorufin-O-deethylase (EROD) activity assay using H4IIE cells to check for dioxin-like chemicals, and a recombinant gene yeast assay for screening estrogenic chemicals, was conducted to assess the removal efficiencies of trace toxic chemicals by different treatment processes in the waste water treatment plant (WWTP). The effluents were extracted by solid phase extraction (SPE) and were fractionated into three fractions based on polarities. The battery of bioassays was performed for each fraction. In the battery, the toxicities of the effluents were described according to their modes of actions (MOA) or biomarkers and the properties of the toxic chemicals were categorized by their polarities and MOAs. The proposed procedure could be used as a tool to diagnose the toxic characteristics of the complicate mixture. The results showed that cytotoxic, dioxin-like and estrogenic chemicals could be detected in all samples. In the influent, cytotoxic and dioxin-like chemicals were mainly in polar fraction and estrogenic chemicals were in non-polar and moderate-polar fractions. The secondary treatment (active sludge) could remove a small amount of these toxicants. Among different types of advanced treatments, flocculation was good enough to remove most of the cytotoxic chemicals and a combination of flocculation, ozone oxidation, and post-biological treatment could eliminate most of the dioxin-like and estrogenic chemicals.

    2016-01-01

    Full Text Available Background According to general ethical and legal principles, valid consent must be obtained before starting any procedure. Objectives Due to the lack of a standard tool for assessing patients’ capacity to consent to medical treatment in Iran, the present study was carried out aiming to devise a Persian version of a cross-cultural adaptation of the MacArthur competence assessment tool. Patients and Methods By reviewing different methods of cultural translation and adaptation for assessment tools, and due to the lack of consensus on its processes, we selected Wild’s model as one of the most comprehensive methods in this regard. Wild’s (2005 10-stage model includes preparation, forward translation, reconciliation of the forward translation, back translation of reconciliation, back translation review, cognitive debriefing and cognitive review, and finalization, proofreading and final reporting. Using this model, we translated the MacArthur assessment tool and made it adaptable to Iranian patients. Results The MacArthur assessment tool is not dependent on any specific culture and language. As a result, if translation and its scientific adaptation are done based on an integrated and detailed model, the tool can be used for every culture and language. In other words, this tool is not culture-specific; so, it is applicable in cases where a translation is needed, and it can be culturally adapted to suit different societies. Conclusions In the present study, we are able to focus on and prove the efficacy and benefits of this measurement tool.

    Disinfection of drinking water is the most successful measure to reduce water-borne diseases and protect health. However, disinfection byproducts (DBPs) formed from the reaction of disinfectants such as chlorine and monochloramine with organic matter may cause bladder cancer and other adverse health effects. In this study the formation of DBPs through a full-scale water treatment plant serving a metropolitan area in Australia was assessed using in vitro bioanalytical tools, as well as through quantification of halogen-specific adsorbable organic halogens (AOXs), characterization of organic matter, and analytical quantification of selected regulated and emerging DBPs. The water treatment train consisted of coagulation, sand filtration, chlorination, addition of lime and fluoride, storage, and chloramination. Nonspecific toxicity peaked midway through the treatment train after the chlorination and storage steps. The dissolved organic matter concentration decreased after the coagulation step and then essentially remained constant during the treatment train. Concentrations of AOXs increased upon initial chlorination and continued to increase through the plant, probably due to increased chlorine contact time. Most of the quantified DBPs followed a trend similar to that of AOXs, with maximum concentrations observed in the final treated water after chloramination. The mostly chlorinated and brominated DBPs formed during treatment also caused reactive toxicity to increase after chlorination. Both genotoxicity with and without metabolic activation and the induction of the oxidative stress response pathway showed the same pattern as the nonspecific toxicity, with a maximum activity midway through the treatment train. Although measured effects cannot be directly translated to adverse health outcomes, this study demonstrates the applicability of bioanalytical tools to investigate DBP formation in a drinking water treatment plant, despite bioassays and sample preparation not

    Slurry management is a central topic in the agronomic and environmental analysis of intensive livestock production systems. The objective of this study is to compare the environmental performance of two scenarios of collective slurry management for the disposal of excess nitrogen from animal manure. The scenarios are the transfer of slurry and its injection to crop land, and the treatment of slurry in a collective biological treatment station. The study is based on a real case in the West of France, where a group of farmers is developing a collective plan for the disposal of almost 7000 m(3) of excess pig slurry. The evaluation is carried out by Life Cycle Assessment, where emissions and resource consumption are quantified and aggregated into four environmental impact categories: eutrophication, acidification, climate change, and non-renewable energy use. Ammonia emitted is the most important contributor to acidification and eutrophication, while methane contributes most to climate change. Both ammonia and methane are mostly emitted during the storage of slurry and, in the case of the treatment scenario, also during composting the solid fraction of the slurry. The two management strategies are similar with respect to climate change, whereas eutrophication and acidification are twice as large for treatment relative to transfer. Electricity needed for the treatment process is the main contributor to non-renewable energy use for the treatment scenario, while the transfer scenario represents a net energy saving, as energy saved by the reduction of mineral fertiliser use more than compensates for the energy needed for transport and injection of slurry. The overall environmental performance of transfer is better than that of treatment, as it involves less acidification, eutrophication and non-renewable energy use. The method employed and the results obtained in this study can provide elements for a transparent discussion of the advantages and disadvantages of contrasting

    A comparative life cycle assessment (LCA) of two solar-driven advanced oxidation processes, namely heterogeneous semiconductor photocatalysis and homogeneous photo-Fenton, both coupled to biological treatment, is carried out in order to identify the environmentally preferable alternative to treat industrial wastewaters containing non-biodegradable priority hazardous substances. The study is based on solar pilot plant tests using alpha-methyl-phenylglycine as a target substance. The LCA study is based on the experimental results obtained, along with data from an industrial-scale plant. The system under study includes production of the plant infrastructure, chemicals, electricity, transport of all these materials to the plant site, management of the spent catalyst by transport and landfilling, as well as treatment of the biodegradable effluent obtained in a conventional municipal wastewater treatment plant, and excess sludge treatment by incineration. Nine environmental impact categories are included in the LCA: global warming, ozone depletion, human toxicity, freshwater aquatic toxicity, photochemical ozone formation, acidification, eutrophication, energy consumption, and land use. The experimental results obtained in the pilot plant show that solar photo-Fenton is able to obtain a biodegradable effluent much faster than solar heterogeneous photocatalysis, implying that the latter would require a much larger solar collector area in an industrial application. The results of the LCA show that, an industrial wastewater treatment plant based on heterogeneous photocatalysis involves a higher environmental impact than the photo-Fenton alternative, which displays impact scores 80-90% lower in most impact categories assessed. These results are mainly due to the larger size of the solar collector field needed by the plant.

    For long-term management of atopic eczema, the use of skin care creams is recommended, but effectiveness of this treatment is not well established. The objective of this study was to yield data on the skin care properties of a cream with a unique lamellar matrix containing N-palmitoylethanolamine (PEA) and to assess quality-of-life variables in patients with mild to moderate atopic eczema. In this multinational, multicentre, observational, non-controlled, prospective cohort study, patients between 2 and 70 years of age were enrolled. All patients were supplied with the study product sufficient for treatment over the entire study period. Outcome was followed in periods between 3 and 7 days and 4 and 6 weeks after study start. Data were gathered from doctor reports and patient self-assessments via patient questionnaires. Data from 2456 patients entered the database. The mean examination intervals were 6 days for the 3- to 7-day period and 38 days for the 4- to 6-week period. At study end, intensities of erythema, pruritus, excoriation, scaling, lichenification and dryness were significantly reduced with a combined score reduction of 58.6% in the entire population (57.7% in adults > 12 years and 60.5% in children effectiveness (decline of pruritus and loss of sleep) indicated a gain in quality of life in these patients. The reduced use of topical corticosteroids is important in view of safety and pharmacoeconomic implications in the treatment of atopic eczema.

    The role of the mental health nurse in the assessment, diagnosis, treatment, and management of children and adolescents with bipolar disorder in community and hospital settings. In many areas of clinical practice, mental health nurses have more contact with service users than any other professional group. They are therefore well placed to support children and adolescents with bipolar disorder during first contact with primary care services, through engagement with specialist mental health services, and in accessing early intervention and crisis services. This paper summarizes the contribution that child and adolescent mental health nurses make to the care of children and adolescents with bipolar disorder. This paper is based on evidence from systematic reviews; meta-analyses and best practice evidence from CINAHL; EMBASE; MEDLINE, PsychINFO; Cochrane Collaboration; National Institute for Health and Clinical Excellence; National Collaborating Centre for Mental Health; NHS Centre for Reviews and Dissemination; Oxford Centre for Evidence Based Medicine; United States Agency for Healthcare Research and Quality. Child and adolescent mental health nurses work with children and adolescents who have bipolar disorder in a range of settings. These include community mental health services, hospitals, and schools. Due to the multidisciplinary nature of the treatment and management of bipolar disorder during childhood and adolescence, nurses have a major role to play in providing frontline assessment services, monitoring treatment, and delivering psychosocial interventions.

    Full Text Available Background. Adherence is the strongest predictor of successful treatment outcome among children infected with HIV. Our aim was to assess the antiretroviral drugs adherence status of HIV-infected children attending care at a tertiary hospital in Southeastern Nigeria. Method. The study involved a cross-sectional survey of 210 HIV-infected children attending care at a tertiary hospital in Southeastern Nigeria using self-report method of assessment. Optimal ART adherence is defined as patient taking not missing more than 1 dose of combined antiretroviral therapy medication in the preceding 2 weeks prior to the study. Result. A majority of the subjects 191 (91% had good adherence. There was a significant relationship between adherence and patient educational level (p=0.004, duration of treatment (p=0.001, drug administrator (p=0.005, and orphan status (p=0.001. The motivating factor for adherence was “not falling sick as before” while stigma was the most discouraging factor. Conclusion. The adherence level in this study was good. Stigma was an important reason given by patient/caregivers for nonadherence. There is need for concerted effort in addressing this barrier to improve adherence and prevent the emergence of drug resistance and treatment failure.

    The effect on the environment of the establishment and operation of a sludge treatment reed bed system (STRB) is quite limited compared to mechanical sludge dewatering, with its accompanying use of energy and chemicals. The assessment presented here of the investment, operation and maintenance costs of a typical STRB, and of the related environmental impact, is based on the experiences gained from the operation of a large number of STRB in Denmark. There are differences in the environmental perspectives and costs involved in mechanical sludge dewatering and disposal on agricultural land compared to STRB. The two treatment methods were considered for comparison based on a treatment capacity of 550 tons of dry solids per year and with land application of the biosolids in Denmark. The initial capital cost for STRB is higher than a conventional mechanical system; however, an STRB would provide significant power and operating-cost savings, with a significant saving in the overall cost of the plant over 20-30 years. The assessment focuses on the use of chemicals, energy and greenhouse gas emissions and includes emptying, sludge residue quality and recycling. STRB with direct land application is the most cost-effective scenario and has the lowest environmental impact. A sludge strategy consisting of an STRB will be approximately DKK 536,894-647,636 cheaper per year than the option consisting of a new screw press or decanter.

    In this paper, we review the research literature on attachment and eating disorders and suggest a framework for assessing and treating attachment functioning in patients with an eating disorder. Treatment outcomes for individuals with eating disorders tend to be moderate. Those with attachment-associated insecurities are likely to be the least to benefit from current symptom-focused therapies. We describe the common attachment categories (secure, avoidant, anxious), and then describe domains of attachment functioning within each category: affect regulation, interpersonal style, coherence of mind, and reflective functioning. We also note the impact of disorganized mental states related to loss or trauma. Assessing these domains of attachment functioning can guide focused interventions in the psychotherapy of eating disorders. Case examples are presented to illustrate assessment, case formulation, and group psychotherapy of eating disorders that are informed by attachment theory. Tailoring treatments to improve attachment functioning for patients with an eating disorder will likely result in better outcomes for those suffering from these particularly burdensome disorders.

    Full Text Available Abstract Background Cystic Fibrosis (CF is a life-shortening genetic disease in which ~80% of deaths result from loss of lung function linked to inflammation due to chronic bacterial infection (principally Pseudomonas aeruginosa. Pulmonary exacerbations (intermittent episodes during which symptoms of lung infection increase and lung function decreases can cause substantial resource utilization, morbidity, and irreversible loss of lung function. Intravenous antibiotic treatment to reduce exacerbation symptoms is standard management practice. However, no prospective studies have identified an optimal antibiotic treatment duration and this lack of objective data has been identified as an area of concern and interest. Methods We have retrospectively analyzed pulmonary function response data (as forced expiratory volume in one second; FEV1 from a previous blinded controlled CF exacerbation management study of intravenous ceftazidime/tobramycin and meropenem/tobramycin in which spirometry was conducted daily to assess the time course of pulmonary function response. Results Ninety-five patients in the study received antibiotics for at least 4 days and were included in our analyses. Patients received antibiotics for an average of 12.6 days (median = 13, SD = 3.2 days, with a range of 4 to 27 days. No significant differences were observed in mean or median treatment durations as functions of either treatment group or baseline lung disease stage. Average time from initiation of antibiotic treatment to highest observed FEV1 was 8.7 days (median = 10, SD = 4.0 days, with a range of zero to 19 days. Patients were treated an average of 3.9 days beyond the day of peak FEV1 (median = 3, SD = 3.8 days, with 89 patients (93.7% experiencing their peak FEV1 improvement within 13 days. There were no differences in mean or median times to peak FEV1 as a function of treatment group, although the magnitude of FEV1 improvement differed between groups. Conclusions Our

    Full Text Available Analysis of scars in various conditions is essential, but no consensus had been reached on the scar assessment scale to select for a given condition. We reviewed papers to determine the scar assessment scale selected depending on the scar condition and treatment method. We searched PubMed for articles published since 2000 with the contents of the scar evaluation using a scar assessment scale with a Journal Citation Report impact factor >0.5. Among them, 96 articles that conducted a scar evaluation using a scar assessment scale were reviewed and analyzed. The scar assessment scales were identified and organized by various criteria. Among the types of scar assessment scales, the Patient and Observer Scar Assessment Scale (POSAS was found to be the most frequently used scale. As for the assessment of newly developed operative scars, the POSAS was most used. Meanwhile, for categories depending on the treatment methods for preexisting scars, the Vancouver Scar Scale (VSS was used in 6 studies following a laser treatment, the POSAS was used in 7 studies following surgical treatment, and the POSAS was used in 7 studies following a conservative treatment. Within the 12 categories of scar status, the VSS showed the highest frequency in 6 categories and the POSAS showed the highest frequency in the other 6 categories. According to our reviews, the POSAS and VSS are the most frequently used scar assessment scales. In the future, an optimal, universal scar scoring system is needed in order to better evaluate and treat pathologic scarring.

  9. Obesity and Surgical Treatment – A Cost-Effectiveness Assessment for Sweden

    2014-07-01

    Full Text Available Background:The rising trend in the prevalence of obesity has during the past decades become a major public health concern in many countries, as obesity may lead to comorbidities and death. A frequent used marker for obesity is the Body Mass Index (BMI. The cost of treatment for obesity related diseases has become a heavy burden on national health care budget in many countries. While diet and exercise are the cornerstones of weight management, pharmaco­therapy is often needed to achieve and maintain desired weight loss.  In some cases of extreme obesity, bariatric surgery may be recommended. It is expected to increase by 50% in Sweden.Objective: The overall objective was to develop a cost-effectiveness model using the best available evidence to assess the cost-effectiveness of gastric bypass (GBP surgical treatments for obesity in adult patients, in comparison with conventional treatment (CT, in Sweden from a healthcare perspective. With the model we also seeked to identify the lower cut-off point using BMI criteria, for the surgical intervention to be cost-effective. Methods:A micro-simulation model with an underlying Markov methodology was developed, that simulates individual patients. It simulates the outcomes of the patients in terms of treatment costs, life years, and quality adjusted life years (QALY over his/her remaining lifetime. The costs are presented in SEK in the year 2006 price level (1 SEK ≈ 0.11 EUR ≈ 0.14 USD.Results: We estimated that the incremental cost per QALY gained will not exceed SEK 33,000 per QALY in patients with BMI < 35. In patients with BMI > 35 kg/m2, gastric bypass surgery has lower costs compared to conventional treatment. Conclusion: Gastric bypass surgery is a cost-effective intervention compared to conventional treatment consisting of watchful waiting, diet and exercise.

    2013-11-01

    Several studies in human and animals show the clinical effectiveness of low level laser therapy (LLLT) in reducing some types of pain, treating inflammation and wound healing. However, more scientific evidence is required to prove the effectiveness of LLLT since many aspects of the cellular and molecular mechanisms triggered by irradiation of injured tissue with laser remain unknown. Here, we present a methodology that can be used to evaluate the effect of different LLLT irradiation parameters on the treatment of muscle inflammation on animals, through the quantification of four cytokines (TNF-α, IL-1β, IL-2 and IL-6) in systemic blood and histological analysis of muscle tissue. We have used this methodology to assess the effect of LLLT parameters (wavelength, dose, power and type of illumination) in the treatment of inflammation induced in the gastrocnemius muscle of Wistar rats. Results obtained for laser dose evaluation with continuous illumination are presented.

    Eisenstein, W.

    2016-12-01

    This presentation will describe a new method for assessing non-technical site suitability criteria for the siting of stormwater capture, treatment and recharge (or stormwater CTR) facilities in Sonoma County, California, USA. "Non-technical site suitability criteria" include issues such as community acceptance, aesthetics, nuisances and hazards, and compatibility with neighboring land uses, and are distinguished from "technical criteria" such as hydrology and soil characteristics that are the traditional subject of suitability analyses. Non-technical criteria are rarely, if ever, considered in formal siting suitability studies conducted by agencies and municipalities, yet can be fatal to the prospects of a given project's construction if not identified and mitigated. The researchers developed a new method for identifying and spatially characterizing relevant non-technical criteria through interviews and questionnaires with community stakeholders, and introducing those criteria into a spatial multi-criteria decision analysis framework that assesses site suitabilty across a study watershed (the Upper Petaluma River watershed in Sonoma County).

    2012-01-01

    Decrease of fossil fuel dependence and resource saving has become increasingly important in recent years. From this perspective, higher recycling rates for valuable materials (e.g. metals) as well as energy recovery from waste streams could play a significant role substituting for virgin material...... production and saving fossil resources. This is especially important with respect to residual waste (i.e. the remains after source-separation and separate collection) which in Denmark is typically incinerated. In this paper, a life-cycle assessment and energy balance of a pilot-scale waste refinery...... for the enzymatic treatment of municipal solid waste (MSW) is presented. The refinery produced a liquid (liquefied organic materials and paper) and a solid fraction (non-degradable materials) from the initial waste. A number of scenarios for the energy utilization of the two outputs were assessed. Co...

    The traditional oral pharmacological therapy for type 2 diabetes mellitus (T2DM) has been based on the prescription of metformin, a biguanide, as first line antihyperglycemic agent world over. It has been demonstrated that after 3 years of treatment, approximately 50% of diabetic patients could achieve acceptable glucose levels with monotherapy; but by 9 years this had declined to only 25%. Therefore, the implementation of a combined pharmacological therapy acting via different pathways becomes necessary, and its combination with a compound of the sulfonylurea group was along decades the most frequently employed prescription in routine clinical practice. Meglitinides, glitazones and alpha-glucosidase inhibitors were subsequently developed, but the five mentioned groups of oral antihyperglycemic agents are associated with variable degrees of undesirable or even severe cardiovascular events. The gliptins-also called dipeptidyl peptidase 4 (DPP4) inhibitors--are an additional group of antidiabetic compounds with increasing clinical use. We review the status of the gliptins with emphasis on their capabilities to positively or negatively affect the cardiovascular system, and their potential involvement in major adverse cardiovascular events (MACE). Alogliptin, anagliptin, linagliptin, saxagliptin, sitagliptin, teneligliptin and vildagliptin are the compounds currently in clinical use. Regardless differences in chemical structure and metabolic pathways, gliptins as a group exert favorable changes in experimental models. These changes, as an almost general rule, include improved endothelial function, reduction of inflammatory markers, oxidative stress ischemia/reperfusion injury and atherogenesis. In addition, increased adiponectin levels and modest decreases in lipidemia and blood pressure were reported. In clinical settings, several trials--notably the longer one, employing sitagliptin, with a mean follow-up period of 3 years--did not show an increased risk for ischemic

    The high per capita generation of solid waste and the environmental problems in major rural communities of Ensenada, Baja California, have prompted authorities to seek alternatives for waste treatment. In the absence of a selection methodology, three technologies of waste treatment with energy recovery (an anaerobic digester, a downdraft gasifier, and a plasma gasifier) were evaluated, taking the broader social, political, economic, and environmental issues into considerations. Using the scientific literature as a baseline, interviews with experts, decision makers and the community, and waste stream studies were used to construct a hierarchy that was evaluated by the analytic hierarchy process. In terms of the criteria, judgments, and assumptions made in the model, the anaerobic digester was found to have the highest rating and should consequently be selected as the waste treatment technology for this area. The study results showed low sensitivity, so alternative scenarios were not considered. The methodology developed in this study may be useful for other governments who wish to assess technologies to select waste treatment.

    This environmental assessment (EA) examines the potential impacts to the environment from treatment of low-level radioactive liquid and low-level mixed liquid and semi-solid wastes generated at the Nevada Test Site (NTS). The potential impacts of the proposed action and alternative actions are discussed herein in accordance with the National Environmental Policy Act (NEPA) of 1969, as amended in Title 42 U.S.C. (4321), and the US Department of Energy (DOE) policies and procedures set forth in Title 10 Code of Federal Regulations (CFR) Part 1021 and DOE Order 451.1, ``NEPA Compliance Program.`` The potential environmental impacts of the proposed action, construction and operation of a centralized liquid waste treatment facility, were addressed in the Final Environmental Impact Statement for the Nevada Test Site and Off-Site Locations in the State of Nevada. However, DOE is reevaluating the need for a centralized facility and is considering other alternative treatment options. This EA retains a centralized treatment facility as the proposed action but also considers other feasible alternatives.

    Occurrence, removal, consumption and environmental risks of sixteen antibiotics were investigated in several sewage treatment plants (STPs) featuring different treatment levels in Hong Kong, China. Cefalexin, ofloxacin and erythromycin-H(2)O were predominant with concentrations of 1020-5640, 142-7900 and 243-4740 ng/L in influent, respectively; their mass loads were comparable to levels reported in urban regions in China and were at the high end of the range reported for western countries. The target antibiotics behaved differently depending on the treatment level employed at the STPs and relatively higher removal efficiencies (>70%) were observed for cefalexin, cefotaxime, amoxicillin, sulfamethoxazole and chloramphenicol during secondary treatment. ß-lactams were especially susceptible to removal via the activated sludge process while macrolides were recalcitrant (norfloxacin (52%), differed greatly in their removal efficiencies, probably because of disparities in their pK(a) values which resulted in different sorption behaviour in sludge. Overall antibiotic consumption in Hong Kong was back-calculated based on influent mass flows and compared with available prescription and usage data. This model was verified by a good approximation of 82% and 141% to the predicted consumption of total ofloxacin, but a less accurate estimate was obtained for erythromycin usage. Risk assessment indicated that algae are susceptible to the environmental concentrations of amoxicillin as well as the mixture of the nine detected antibiotics in receiving surface waters.

    Penile corporoplasty is a well-established treatment method of congenital penile deviation (CPD). Anatomical results are good with only slight differences between surgical procedures used. The disease however has huge influence on young male quality of life. This issue is not well analyzed in the literature. The aim of the study was to evaluate quality of life of the patients affected with CPD before and after the surgical treatment Study population consisted of 107 patients with CPD referred for surgical management. Patients were evaluated with not only clinical assessment, but also by four questionnaires measuring various aspects of quality of life. They were: Short-Form Medical Outcomes, Sexual Quality of Life Questionnaire for Man, Beck Depression Inventory, and International Index of Erectile Function. Quality of life measurements showed deep decrease in the general quality of life, sexual performance, depression scale, as well as in physical and mental health in men with CPD. All these parameters were restored to normal after the successful surgical treatment with any method. CPD deeply decreases the quality of life of the affected men in many aspects. Surgical treatment is able to repair the anatomical deformity and as well as significantly restore the patients' psychosocial well-being. © 2015 International Society for Sexual Medicine.

    2017-06-19

    Background The German Institute for Quality and Efficiency in Health Care (IQWiG) recommends the concept of the efficiency frontier to assess health care interventions. The efficiency frontier supports regulatory decisions on reimbursement prices for the appropriate allocation of health care resources. Until today this cost-benefit assessment framework has only been applied on the basis of individual patient-relevant endpoints. This contradicts the reality of a multi-dimensional patient benefit. Objective The objective of this study was to illustrate the operationalization of multi-dimensional benefit considering the uncertainty in clinical effects and preference data in order to calculate the efficiency of different treatment options for hepatitis C (HCV). This case study shows how methodological challenges could be overcome in order to use the efficiency frontier for economic analysis and health care decision-making. Method The operationalization of patient benefit was carried out on several patient-relevant endpoints. Preference data from a discrete choice experiment (DCE) study and clinical data based on clinical trials, which reflected the patient and the clinical perspective, respectively, were used for the aggregation of an overall benefit score. A probabilistic efficiency frontier was constructed in a Monte Carlo simulation with 10000 random draws. Patient-relevant endpoints were modeled with a beta distribution and preference data with a normal distribution. The assessment of overall benefit and costs provided information about the adequacy of the treatment prices. The parameter uncertainty was illustrated by the price-acceptability-curve and the net monetary benefit. Results Based on the clinical and preference data in Germany, the interferon-free treatment options proved to be efficient for the current price level. The interferon-free therapies of the latest generation achieved a positive net cost-benefit. Within the decision model, these therapies

    Pfingston, M.; Arnish, J.; LePoire, D.; Chen, S.-Y.

    1998-10-14

    Past practices at US Department of Energy (DOE) field facilities resulted in the presence of trace amounts of radioactive materials in some hazardous chemical wastes shipped from these facilities. In May 1991, the DOE Office of Waste Operations issued a nationwide moratorium on shipping all hazardous waste until procedures could be established to ensure that only nonradioactive hazardous waste would be shipped from DOE facilities to commercial treatment, storage, and disposal (TSD) facilities. To aid in assessing the potential impacts of shipments of mixed radioactive and chemically hazardous wastes, a radiological assessment computer model (or code) was developed on the basis of detailed assessments of potential radiological exposures and doses for eight commercial hazardous waste TSD facilities. The model, called TSD-DOSE, is designed to incorporate waste-specific and site-specific data to estimate potential radiological doses to on-site workers and the off-site public from waste-handling operations at a TSD facility. The code is intended to provide both DOE and commercial TSD facilities with a rapid and cost-effective method for assessing potential human radiation exposures from the processing of chemical wastes contaminated with trace amounts of radionuclides.

    Full Text Available Background: Aconitum napellus is a classic resource of complementary medicine for the treatment of patients exhibiting neurological symptoms of anxiety. Aim: To assess the action of homeopathic medicine Acon in the treatment of generalized anxiety in an experimental model using rats. Methods: 48 adult (two to three months old male Wistar rats (Rattus rattus were randomly divided in six groups (n= 8/treatment and given the following treatments by gastric tube along 10 days: 1 control (diazepam 1 mg/kg/day; 2 negative control (0.15 mL saline solution/day; 3 ACH6 (0.15 mL Acon (6cH/day; 4 ACH12 (0.15 mL Acon 12cH/day; 5 ACH30 (0.15 mL Acon 30cH/day; and 6 ALC30 (0.15 mL 30% cereal alcohol/day. Behavioral effects were blindly and randomly assessed in elevated plus maze (EPM and open field test. Results: Acon in dilutions 12cH and 30cH exhibited possible anxiolytic effects on the central nervous system (CNS since they increased the number of entries in the EPM open arms (12cH and 30cH and the permanence time in the EPM open arms (30cH only. In the open field test the homeopathic preparations did not show effects on the locomotor system of rats. Conclusion: Dilutions 12cH and 30cH of Acon exhibited anxiolytic effects on the CNS in an animal experimental model.

    Full Text Available Decubitus ulcers in the oral mucosa tend to be very painful causing discomforting sensation in patients in speaking and eating. Low energy lasers can provide an alternative method for the treatment of these ulcers.The aim of the present paper was to assess clinically the healing effect of low level laser irradiation on oral mucosa decubitus ulcers.Material and methods: A total of 90 patients with decubitus ulcers were treated in the present study; they were randomly assigned to three groups: group I included 30 patients treated with low level laser (LLL irradiation (wavelength of irradiation 658 nm; group II - 30 patients treated with laser irradiation of 904 nm; and group III (controls - 30 patients who received a standard conventional treatment with "granofurin" and "solcoseryl".The treatment sessions in all three groups were administered once daily. The patients in groups I and II were irradiated with focused irradiation at an angle from a distance using a conically shaped light probe 3 mm in diameter. The irradiated area was 0.5 cm2. The light was focused on the oral mucosa ulcer and the surrounding inflamed mucosa at a distance of 0.5 to 1 cm. Diode lasers were used in the study. The dosage of irradiation was 1.2 J/cm2.Results and discussion: The treatment effect was evaluated by changes in the studied parameters: pain intensity, erythema, and epithelialization. They were assessed at baseline, and at days 1, 3 and 5. Conclusions: LLLT administered with the proposed methodology manages pain rapidly and accelerates the process of epithelialization of decubitus ulcers in the soft tissues of the mouth.

    The purpose of this research is to develop a 4DCBCT-based dose assessment method for calculating actual delivered dose for patients with significant respiratory motion or anatomical changes during the course of SBRT. To address the limitation of 4DCT-based dose assessment, we propose to calculate the delivered dose using time-varying (‘fluoroscopic’) 3D patient images generated from a 4DCBCT-based motion model. The method includes four steps: (1) before each treatment, 4DCBCT data is acquired with the patient in treatment position, based on which a patient-specific motion model is created using a principal components analysis algorithm. (2) During treatment, 2D time-varying kV projection images are continuously acquired, from which time-varying ‘fluoroscopic’ 3D images of the patient are reconstructed using the motion model. (3) Lateral truncation artifacts are corrected using planning 4DCT images. (4) The 3D dose distribution is computed for each timepoint in the set of 3D fluoroscopic images, from which the total effective 3D delivered dose is calculated by accumulating deformed dose distributions. This approach is validated using six modified XCAT phantoms with lung tumors and different respiratory motions derived from patient data. The estimated doses are compared to that calculated using ground-truth XCAT phantoms. For each XCAT phantom, the calculated delivered tumor dose values generally follow the same trend as that of the ground truth and at most timepoints the difference is less than 5%. For the overall delivered dose, the normalized error of calculated 3D dose distribution is generally less than 3% and the tumor D95 error is less than 1.5%. XCAT phantom studies indicate the potential of the proposed method to accurately estimate 3D tumor dose distributions for SBRT lung treatment based on 4DCBCT imaging and motion modeling. Further research is necessary to investigate its performance for clinical patient data.

    The application of floating treatment wetlands (FTWs) in point and non-point source pollution control has received much attention recently. Although the potential of this emerging technology is supported by various studies, quantifying FTW performance in urban retention ponds remains elusive due to significant research gaps. Actual urban retention pond water was utilized in this mesocosm study to evaluate phosphorus and nitrogen removal efficiency of FTWs. Multiple treatments were used to investigate the contribution of each component in the FTW system with a seven-day retention time. The four treatments included a control, floating mat, pickerelweed (Pontederia cordata L.), and softstem bulrush (Schoenoplectus tabernaemontani). The water samples collected on Day 0 (initial) and 7 were analyzed for total phosphorus (TP), total particulate phosphorus, orthophosphate, total nitrogen (TN), organic nitrogen, ammonia nitrogen, nitrate-nitrite nitrogen, and chlorophyll-a. Statistical tests were used to evaluate the differences between the four treatments. The effects of temperature on TP and TN removal rates of the FTWs were described by the modified Arrhenius equation. Our results indicated that all three FTW designs, planted and unplanted floating mats, could significantly improve phosphorus and nitrogen removal efficiency (%, E-TP and E-TN) compared to the control treatment during the growing season, i.e., May through August. The E-TP and E-TN was enhanced by 8.2% and 18.2% in the FTW treatments planted with the pickerelweed and softstem bulrush, respectively. Organic matter decomposition was likely to be the primary contributor of nutrient removal by FTWs in urban retention ponds. Such a mechanism is fostered by microbes within the attached biofilms on the floating mats and plant root surfaces. Among the results of the four treatments, the FTWs planted with pickerelweed had the highest E-TP, and behaved similarly with the other two FTW treatments for nitrogen removal

    When selecting a landfill leachate treatment method the contaminant composition of the leachate should be considered in order to obtain the most cost-effective treatment option. In this study the filter material pine bark was evaluated as a treatment for five landfill leachates originating from different cells of the same landfill in Sweden. The objective of the study was to determine the uptake, or release, of metals and dissolved organic carbon (DOC) during a leaching test using the pine bark filter material with the five different landfill leachates. Furthermore the change of toxicity after treatment was studied using a battery of aquatic bioassays assessing luminescent bacteria (Vibrio fischeri) acute toxicity (30-min Microtox®), immobility of the crustacean Daphnia magna, growth inhibition of the algae Pseudokirchneriella subcapitata and the aquatic plant Lemna minor; and genotoxicity with the bacterial Umu-C assay. The results from the toxicity tests and the chemical analysis were analyzed in a Principal Component Analysis and the toxicity of the samples before and after treatment was evaluated in a toxicity classification. The pine bark filter material reduced the concentrations of metal contaminants from the landfill leachates in the study, with some exceptions for Cu and Cd. The Zn uptake of the filter was high for heavily contaminated leachates (≥73%), although some desorption of zinc occurred in less contaminated waters. Some of the leachates may require further treatment due to discharge into a natural recipient in order to reduce the risk of possible biological effects. The difference in pH changes between the different leachates was probably due to variations in buffering capacity, affected by physicochemical properties of the leachate. The greatest desorption of phenol during filtration occurred in leachates with high conductivity or elevated levels of metals or salts. Generally, the toxicity classification of the leachates implies that although

    Since its introduction into dentistry in 1998, CBCT has become increasingly utilized for orthodontic diagnosis, treatment planning and research. The utilization of CBCT for these purposes has been facilitated by the relative advantages of three-dimensional (3D) over two-dimensional radiography. Despite many suggested indications of CBCT, scientific evidence that its utilization improves diagnosis and treatment plans or outcomes has only recently begun to emerge for some of these applications. This article provides a comprehensive and current review of key studies on the applications of CBCT in orthodontic therapy and for research to decipher treatment outcomes and 3D craniofacial anatomy. The current diagnostic and treatment planning indications for CBCT include impacted teeth, cleft lip and palate and skeletal discrepancies requiring surgical intervention. The use of CBCT in these and other situations such as root resorption, supernumerary teeth, temporomandibular joint (TMJ) pathology, asymmetries and alveolar boundary conditions should be justified on the basis of the merits relative to risks of imaging. CBCT has also been used to assess 3D craniofacial anatomy in health and disease and of treatment outcomes including that of root morphology and angulation; alveolar boundary conditions; maxillary transverse dimensions and maxillary expansion; airway morphology, vertical malocclusion and obstructive sleep apnoea; TMJ morphology and pathology contributing to malocclusion; and temporary anchorage devices. Finally, this article utilizes findings of these studies and current voids in knowledge to provide ideas for future research that could be beneficial for further optimizing the use of CBCT in research and the clinical practice of orthodontics.

    Full Text Available Abstract Background To investigate the presence of pathogenic microbes on chiropractic treatment tables in one outpatient teaching clinic. Additional aims were to test inexpensive disinfectants on tables that may kill microbes and suggest infection control measures for chiropractic offices, clinics and classrooms. The aim of the study was to assess the presence of pathogenic microbes on treatment tables in one outpatient teaching clinic and determine a simple behavioral model for infection control including table disinfection and accepted hand washing and sanitizing protocols. Methods 10 treatment tables were selected and sampled for possible microbial flora on face and hand pieces. Samples were cultured on MacConky's agar and mannitol salt agar, labeled and incubated for up to 48 hours. Confirmatory testing of microbes to determine if drug resistant flora were present was performed. Among tables tested, 5 were selected to test disinfectants. One-half of the face piece and 1 hand piece were treated with two different wipes and then post-tested for microbes. Results Pathogenic microbes were present on chiropractic treatment tables including methicillin-resistant Staph aureus. Simple disinfectants neutralized the pathogens. A rudimentary disinfection procedure and infection control measures are suggested based on the findings. Conclusion Pathogenic microbes may be present on chiropractic treatment tables and can be effectively killed with proper disinfecting. Hand washing/sanitizing is an important measure in infection control as is table disinfecting. Rudimentary behavioral changes to improve chiropractic clinic infection control are needed. More comprehensive behavioral models are needed. All teaching clinics and private chiropractic offices should adopt infection control practices including routine table disinfecting and hand sanitizing. Effective measures can be put in place at minimal costs. Accrediting bodies of chiropractic institutions

    Selection of treatment technologies without considering the environmental, economic and social factors associated with each geographical context risks the occurrence of negative impacts that were not properly foreseen, working against the sustainable performance of the technology. The principal aim of this study was to evaluate 12 technologies for decentralized treatment of domestic wastewater applicable to peri-urban communities using sustainability approaches and, at the same time, continuing a discussion about how to address a more integrated assessment of overall sustainability. For this, a set of 13 indicators that embody the environmental, economic and social approach for the overall sustainability assessment were used by means of a target plot diagram as a tool for integrating indicators that represent a holistic analysis of the technologies. The obtained results put forward different degrees of sustainability, which led to the selection of: septic tank+land infiltration; up-flow anaerobic reactor+high rate trickling filter and septic tank+anaerobic filter as the most sustainable and attractive technologies to be applied in peri-urban communities, according to the employed indicators.

  14. A theoretical perspective to inform assessment and treatment strategies for animal hoarders.

    Patronek, Gary J; Nathanson, Jane N

    2009-04-01

    Animal hoarding is a poorly understood, maladaptive, destructive behavior whose etiology and pathology are only beginning to emerge. We compare and contrast animal hoarding to the compulsive hoarding of objects and proceed to draw upon attachment theory, the literature of personality disorder and trauma, and our own clinical experience to propose a developmental trajectory. Throughout life, there is a persistent struggle to form a functional attachment style and achieve positive social integration. For some people, particularly those affected by a dysfunctional primary attachment experience in childhood, a protective, comforting relationship with animals may form an indelible imprint. In adulthood, when human attachment has been chronically problematic, compulsive caregiving of animals can become the primary means of maintaining or building a sense of self. Improving assessment and treatment of animal hoarders requires attention to contributing psychosocial conditions, while taking into account the centrality of the animals to the hoarder's identity, self-esteem and sense of control. It is our hope that the information presented will provide a basis upon which clinicians can focus their own counseling style, assessment, and methods of treatment.

    Full Text Available Abstract Background The degree of ADHD-related difficulties – reflecting overall impairment, social functioning, and quality of life – may be perceived differently by adolescent patients, parents and physicians. The primary aim of this study was to investigate ADHD-related difficulties during atomoxetine treatment, as perceived by the three different raters. Secondary objectives focused on effectiveness and tolerability of atomoxetine treatment in a population of adolescent patients with ADHD. Methods Adolescents with ADHD, aged 12–17 years, received open-label atomoxetine (0.5–1.2 mg/kg/day up to 24 weeks. ADHD-related difficulties at various times of the day were rated using the Global Impression of Perceived Difficulties (GIPD instrument. Inter-rater agreement was analyzed using Cohen's Kappa with 95% confidence intervals (95% CI. ADHD-Rating Scale (ADHD-RS and Clinical Global Impression Severity (GGI-S scores were assessed by the investigator; and spontaneous adverse events, vital signs and laboratory parameters were collected for tolerability assessments. Results 159 patients received atomoxetine. Patients' baseline mean GIPD total ratings were significantly lower than parents' and physicians' scores (12.5 [95%CI 11.6;13.5] vs. 17.2 [16.2;18.2] and 18.8 [17.8;19.8]. For all raters, GIPD scores significantly improved over time. Changes were greatest within the first two weeks. Kappa coefficients varied between 0.186 [0.112;0.259] and 0.662 [0.529;0.795], with strongest agreements between parent and physician assessments, and significant improvements of patient/physician agreements over time (based on 95% CIs. ADHD-RS and CGI-S scores significantly improved over the course of the study (based on 95% CIs. Tolerability results were consistent with earlier reports. Conclusion ADHD-related difficulties were perceived differently by the raters in this open-label trial, but consistently improved during atomoxetine treatment. The GIPD

    Full Text Available There is currently great concern about the processes that directly or indirectly contribute to the potential for global warming, such as stratospheric ozone depletion or acidification. In this context, and provided that treated water is a basic public utility in urban centers around the world as well as in some rural areas, its impact on the environment is of great interest. Therefore, this study applied the environmental methodology of Life Cycle Assessment (LCA to evaluate the environmental loads of four potable water treatment plants (PWTPs located in northeastern Colombia following the international guidelines delineated in ISO 14040. The different stages of the drinking water process were thoroughly assessed, from the catchment point through pumping to the distribution network. The functional unit was defined as 1 m3 of drinking water produced at the plant. The data were analyzed through the database Ecoinvent v.3.01, and modeled and processed in the software LCA-Data Manager. The results showed that in plants PLA-CA and PLA-PO, the flocculation process has the highest environmental load, which is mostly attributable to the coagulant agent, with a range between 47-73% of the total impact. In plants PLA-TON and PLA-BOS, electricity consumption was identified as the greatest impact source, with percentages ranging from 67 to 85%. Treatment processes and techniques, bioclimatic conditions and culturally driven consumption behavior varied from region to region. Furthermore, changes in treatment processes and techniques are likely to affect the environment during all stages of a plant’s operational cycle.

    For most water treatment plants, a significant number of performance data variables are attained on a time series basis. Due to the interconnectedness of the variables, it is often difficult to assess over-arching trends and quantify operational performance. The objective of this study was to establish simple and reliable predictive models to correlate target variables with specific measured parameters. This study presents a multivariate analysis of the physicochemical parameters of municipal wastewater. Fifteen quality and quantity parameters were analyzed using data recorded from 2010 to 2016. To determine the overall quality condition of raw and treated wastewater, a Wastewater Quality Index (WWQI) was developed. The index summarizes a large amount of measured quality parameters into a single water quality term by considering pre-established quality limitation standards. To identify treatment process performance, the interdependencies between the variables were determined by using Principal Component Analysis (PCA). The five extracted components from the 15 variables accounted for 75.25% of total dataset information and adequately represented the organic, nutrient, oxygen demanding, and ion activity loadings of influent and effluent streams. The study also utilized the model to predict quality parameters such as Biological Oxygen Demand (BOD), Total Phosphorus (TP), and WWQI. High accuracies ranging from 71% to 97% were achieved for fitting the models with the training dataset and relative prediction percentage errors less than 9% were achieved for the testing dataset. The presented techniques and procedures in this paper provide an assessment framework for the wastewater treatment monitoring programs. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Panic disorder, a psychiatric disorder characterised by frequent panic attacks, is the most common anxiety disorder, affecting 2 to 6% of the general population. No one line of treatment has been found to be superior, making a risk-benefit assessment of the treatments available useful for treating patients. Choice of treatment depends on a number of issues, including the adverse effect profile, efficacy and the presence of concomitant syndromes. Tricyclic antidepressants (TCAs) are beneficial in the treatment of panic disorder. They have a proven efficacy, are affordable and are conveniently administered. Adverse effects, including jitteriness syndrome, bodyweight gain, anticholinergic effects and orthostatic hypotension are commonly associated with TCAs, but can be managed successfully. Selective serotonin (5-hydroxytryptamine; 5HT) reuptake inhibitors are also potential first line agents and are well tolerated and effective, with a favourable adverse effects profile. There is little risk in overdose or of anticholinergic effects. Adverse effects include sedation, dyspepsia and headache early in treatment, and sexual dysfunction and increased anxiety, but these can be effectively managed with proper dosage escalation and management. Benzodiazepines are an effective treatment, providing short-term relief of panic-related symptoms. Patients respond to treatment quickly, providing rapid relief of symptoms. Adverse effects include ataxia and drowsiness, and cognitive and psycho-motor impairment. There are reservations over their first-line use because of concerns regarding abuse and dependence. Monoamine oxidase inhibitors, because of their adverse effects profile, potential drug interactions, dietary restrictions, gradual onset of effect and overdose risk, are not considered to be first-line agents. They are effective however, and should be considered for patients with refractory disease. Valproic acid (valproate sodium), while not intensively studied, shows

    We are developing a CAD system for bladder cancer treatment response assessment in CT. We compared the performance of the deep-learning convolution neural network (DL-CNN) using different network sizes, and with and without transfer learning using natural scene images or regions of interest (ROIs) inside and outside the bladder. The DL-CNN was trained to identify responders (T0 disease) and non-responders to chemotherapy. ROIs were extracted from segmented lesions in pre- and post-treatment scans of a patient and paired to generate hybrid pre-post-treatment paired ROIs. The 87 lesions from 82 patients generated 104 temporal lesion pairs and 6,700 pre-post-treatment paired ROIs. Two-fold cross-validation and receiver operating characteristic analysis were performed and the area under the curve (AUC) was calculated for the DL-CNN estimates. The AUCs for prediction of T0 disease after treatment were 0.77+/-0.08 and 0.75+/-0.08, respectively, for the two partitions using DL-CNN without transfer learning and a small network, and were 0.74+/-0.07 and 0.74+/-0.08 with a large network. The AUCs were 0.73+/-0.08 and 0.62+/-0.08 with transfer learning using a small network pre-trained with bladder ROIs. The AUC values were 0.77+/-0.08 and 0.73+/-0.07 using the large network pre-trained with the same bladder ROIs. With transfer learning using the large network pretrained with the Canadian Institute for Advanced Research (CIFAR-10) data set, the AUCs were 0.72+/-0.06 and 0.64+/-0.09, respectively, for the two partitions. None of the differences in the methods reached statistical significance. Our study demonstrated the feasibility of using DL-CNN for the estimation of treatment response in CT. Transfer learning did not improve the treatment response estimation. The DL-CNN performed better when transfer learning with bladder images was used instead of natural scene images.

    Objective This study examined the efficacy of a new cognitive debiasing intervention in reducing decision-making errors in the assessment of pediatric bipolar disorder (PBD). Method The study was a randomized controlled trial using case vignette methodology. Participants were 137 mental health professionals working in different regions of the US (M=8.6±7.5 years of experience). Participants were randomly assigned to a (1) brief overview of PBD (control condition), or (2) the same brief overview plus a cognitive debiasing intervention (treatment condition) that educated participants about common cognitive pitfalls (e.g., base-rate neglect; search satisficing) and taught corrective strategies (e.g., mnemonics, Bayesian tools). Both groups evaluated four identical case vignettes. Primary outcome measures were clinicians’ diagnoses and treatment decisions. The vignette characters’ race/ethnicity was experimentally manipulated. Results Participants in the treatment group showed better overall judgment accuracy, p clinical recommendations, particularly in cases where participants missed comorbid conditions, failed to detect the possibility of hypomania or mania in depressed youths, and misdiagnosed classic manic symptoms. In contrast, effects of patient race were negligible. Conclusions The cognitive debiasing intervention outperformed the control condition. Examining specific heuristics in cases of PBD may identify especially problematic mismatches between typical habits of thought and characteristics of the disorder. The debiasing intervention was brief and delivered via the Web; it has the potential to generalize and extend to other diagnoses as well as to various practice and training settings. PMID:26727411

    Neurolymphomatosis is a rare neurological manifestation of non-Hodgkin's lymphoma (NHL) and it may be its first and sole manifestation. Diagnosis is often difficult and nerve biopsy is generally required. However, this it is not always possible to perform or is not conclusive. We present the case of a 66-year-old woman diagnosed with giant B-cell NHL. After 6 cycles of chemotherapy, imaging and molecular biology techniques showed complete remission. At four months after treatment, the patient complained of low back pain of radicular distribution. CT and MRI imaging showed signs of lymphoproliferative activity of L5 and also lesions to thoracic nerve roots. A PET-CT was requested in order to complete the diagnosis and plan the treatment. Imaging confirmed the presence of tumor recurrence with neurolymphomatosis and also indicated lesions on the chest and abdominal level. Thus, it was decided to start a new line of chemotherapy, without performing the histological study through biopsy. This case illustrates the important role played by PET-CT imaging in neurolymphomatosis diagnosis. This technique can help the patient avoid more aggressive procedures, such as a biopsy, and can also be useful in the follow-up and assessment of the treatment response to NHL-diagnosed patients.

    Dissociative experiences are common in traumatized individuals, and can sometimes be mistaken for psychosis. It is difficult to identify pathological dissociation in the treatment of traumatized refugees, because there is a lack of systematic clinical descriptions of dissociative phenomena in refugees. Furthermore, we are currently unaware of how dissociation measures perform in this clinical group. To describe the phenomenology of dissociative symptoms in Bosnian treatment-seeking refugees in Denmark. As a part of a larger study, dissociation was assessed systematically in 86 Bosnian treatment-seeking refugees using a semi-structured clinical interview (Structured Interview for Disorders of Extreme Stress-dissociation subscale; SIDES-D) and a self-report scale (Dissociative Experiences Scale; DES). The SIDES-D indicated twice as high prevalence of pathological dissociation as the DES. According to the DES, 30% of the refugees had pathological dissociation 15 years after their resettlement. On the SIDES-D, depersonalization and derealization experiences were the most common. Also, questions about depersonalization and derealization at times elicited reporting of visual and perceptual hallucinations, which were unrelated to traumatic re-experiencing. Questions about personality alteration elicited spontaneous reports of a phenomenon of "split" pre- and post-war identity in the refugee group. Whether this in fact is a dissociative phenomenon, characteristic of severe traumatization in adulthood, needs further examination. Knowledge of dissociative symptoms in traumatized refugees is important in clinical settings to prevent misclassification and to better target psychotherapeutic interventions. Much development in the measurement of dissociation in refugees is needed.

    2011-01-01

    Background This exploratory study was conducted in an effort to demonstrate that bioelectrical impedance analysis (BIA) phase angle measurement is a novel tool for monitoring the effectiveness of a wound care regimen at a regional level and is valuable in comparing that status with the overall metabolic health of the patient. Isolating and measuring the extent to which nutritional supplementation contributes to the healing process is difficult and confounded by the many treatment modalities patients undergo. Objective The authors conducted a limited exploratory study to determine whether regional phase angle measurements accurately reflected the status of chronic nonhealing wounds. This information would potentially provide the ability to quantitatively evaluate of the role of nutritional supplementation in wounds of varying etiologies by comparing regional BIA phase angle measurement with overall BIA phase angle measurement. Methods Eleven patients with wounds of varying etiologies were selected to participate. Each patient underwent a treatment regimen specific to his or her condition, and all patients were given JUVEN® nutritional supplement. Results and Conclusion In all patients, the BIA phase angle measurement mirrored the health of the wound and provided an accurate tool for assessing the regional tissue health, a valuable insight in measuring the effectiveness of a systemic treatment.

    Extra-abdominal desmoid fibromatosis (EADF) is a benign tumoral condition, classically managed by more or less radical and sometimes mutilating excision. This treatment strategy is associated with a recurrence rate of nearly 50% according to various reports. EADF may show spontaneous stabilization over time. A retrospective series of 26 cases of EADF managed by simple observation was studied to assess spontaneous favorable evolution and identify possible factors impacting evolution. Eleven cases were of primary EADF with no treatment or surgery, and 15 of recurrence after surgery with no adjuvant treatment. MRI was the reference examination during follow-up. Twenty-four cases showed stabilization at a median 14 months; there were no cases of renewed evolution after stabilization. One primary tumor showed spontaneous regression, and one recurrence still showed evolution at end of follow-up (23 months). The sole factor impacting potential for evolution was prior surgery. No radiologic or pathologic criteria of evolution emerged from analysis. The present series, one of the largest dedicated to EADF managed by observation, confirmed recent literature findings: a conservative "wait-and-see" attitude is reasonable and should be considered when large-scale resection would entail significant functional or esthetic impairment.

    The aim of this study was to evaluate the long-term clinical predictive value of the periodontal risk assessment diagram surface (PRAS) score and the influence of patient compliance on the treatment outcomes. Thirty subjects suffering from periodontitis were re-examined 6-12 years after the initial diagnosis and periodontal treatments. The baseline PRAS score was calculated from the initial clinical and radiograph records. Patients were then classified into a low-to-moderate (0-20) or a high-risk group (>20). Patients who did not attend any supportive periodontal therapy were classified into a non-compliant group. PRAS and compliance were correlated to the mean tooth loss (TL)/year and the mean variation in the number of periodontal pockets with a probing depth (PPD) >4 mm. TL was 0.11 for the low-to-moderate-risk group and 0.26 for the high-risk group (p<0.05); PPD number reduction was 2.57 and 2.17, respectively, and bleeding on probing reduction was 6.7% and 23.3%, respectively. Comparing the compliance groups, the PPD number reduction was 3.39 in the compliant group and 1.40 in the non-compliant group (p<0.05). This study showed the reliability of PRAS in evaluating long-term TL and patient susceptibility to periodontal disease. Our data confirmed the positive influence of patient compliance on periodontal treatment outcomes.

    Full Text Available Background. The Janeway Children’s Hospital previously enacted a number of measures to improve pain management for patients in its emergency department (ED. While improvements were demonstrated, rates for the timely assessment and treatment of pain remain below standards of care. Objectives. The study objectives are to investigate the impact of the previous attempts to improve the treatment of pain and to explore ways to further improve pain management in the ED. Methods. Key informant interviews and a focus group were conducted with nurses, physicians, and parents whose children were identified as having severe pain. Results. Interviews were conducted with 31 parents or children, 9 physicians, and 8 nurses. The focus group was attended by 15 nurses. Previous initiatives were viewed as improvements. Continued barriers include difficulties in accurately capturing the level of pain, issues in treating pain for specific types of patients, and inadequacy in addressing patients in severe pain. Conclusion. Changes in pain treatment protocols can result in positive impacts but are likely insufficient on their own to achieve desired standards of care. Consistent measurement and engagement with staff can identify additional opportunities for improving pain management within an ED setting.

    With increased worldwide awareness of environmental issues, healthcare waste (HCW) management has received much attention from both researchers and practitioners over the past decade. The task of selecting the optimum treatment technology for HCWs is a challenging decision making problem involving conflicting evaluation criteria and multiple stakeholders. In this paper, we develop an integrated decision making framework based on cloud model and MABAC method for evaluating and selecting the best HCW treatment technology from a multiple stakeholder perspective. The introduced framework deals with uncertain linguistic assessments of alternatives by using interval 2-tuple linguistic variables, determines decision makers' relative weights based on the uncertainty and divergence degrees of every decision maker, and obtains the ranking of all HCW disposal alternatives with the aid of an extended MABAC method. Finally, an empirical example from Shanghai, China, is provided to illustrate the feasibility and effectiveness of the proposed approach. Results indicate that the methodology being proposed is more suitable and effective to handle the HCW treatment technology selection problem under vague and uncertain information environment.

    Dental environment may be a source of stress for the young patient. Such stressful conditions may provoke fear in anxious children. It is well known that stress produces an activation adrenal steroid secretion. Among the methods for assessing child dental fear, measurement of salivary cortisol level is a simple method, because especially in children, sampling of saliva is easy, and cortisol levels in saliva closely mirror serum free cortisol levels, independent of salivary flow rate. For this study, the salivary cortisol levels of 8 children (mean age 5.6 yr) were measured receiving initial dental treatment. Saliva samples were collected via cotton rolls placed to the floor of the mouth at four stages; prior to treatment, during cavitation, placement of the liner and the restoration. Statistical comparison of the results were done by Student-t test. The increase in salivary cortisol levels during cavitation at the first and secondary appointments were significant (p0.05). The results of this study suggest that in restorative procedures, mostly it is the cavitation step that creates stress and anxiety in children. Knowledge of the most stressful condition may be helpful for the dentist to prepare the child to treatment steps.

    Revegetation and soil restoration efforts, often associated with erosion control measures on disturbed soils, are rarely monitored or otherwise evaluated in terms of improved hydrologic, much less, ecologic function and longer term sustainability. As in many watersheds, sediment is a key parameter of concern in the Tahoe Basin, particularly fine sediments less than about ten microns. Numerous erosion control measures deployed in the Basin during the past several decades have under-performed, or simply failed after a few years and new soil restoration methods of erosion control are under investigation. We outline a comprehensive, integrated field-based evaluation and assessment of the hydrologic function associated with these soil restoration methods with the hypothesis that restoration of sustainable function will result in longer term erosion control benefits than that currently achieved with more commonly used surface treatment methods (e.g. straw/mulch covers and hydroseeding). The monitoring includes cover-point and ocular assessments of plant cover, species type and diversity; soil sampling for nutrient status; rainfall simulation measurement of infiltration and runoff rates; cone penetrometer measurements of soil compaction and thickness of mulch layer depths. Through multi-year hydrologic and vegetation monitoring at ten sites and 120 plots, we illustrate the results obtained from the integrated monitoring program and describe how it might guide future restoration efforts and monitoring assessments.

    Full Text Available Current assessment of orthotopic tumor models in animals utilizes survival as the primary therapeutic end point. In vivo bioluminescence imaging (BLI is a sensitive imaging modality that is rapid and accessible, and may comprise an ideal tool for evaluating antineoplastic therapies [1 ]. Using human tumor cell lines constitutively expressing luciferase, the kinetics of tumor growth and response to therapy have been assessed in intraperitoneal [2], subcutaneous, and intravascular [3] cancer models. However, use of this approach for evaluating orthotopic tumor models has not been demonstrated. In this report, the ability of BLI to noninvasively quantitate the growth and therapeuticinduced cell kill of orthotopic rat brain tumors derived from 9L gliosarcoma cells genetically engineered to stably express firefly luciferase (9LLuc was investigated. Intracerebral tumor burden was monitored over time by quantitation of photon emission and tumor volume using a cryogenically cooled CCD camera and magnetic resonance imaging (MRI, respectively. There was excellent correlation (r=0.91 between detected photons and tumor volume. A quantitative comparison of tumor cell kill determined from serial MRI volume measurements and BLI photon counts following 1,3-bis(2-chloroethyl-1-nitrosourea (BCNU treatment revealed that both imaging modalities yielded statistically similar cell kill values (P=.951. These results provide direct validation of BLI imaging as a powerful and quantitative tool for the assessment of antineoplastic therapies in living animals.

    Full Text Available Objective. Systemic lupus erythematosus (SLE is treated with anti-inflammatory and immunosuppressive drugs and off-label biologics. Belimumab is the first biologic approved after 50 years as an add-on therapy for active disease. This paper summarizes a health technology assessment performed in Italy. Methods. SLE epidemiology and burden were assessed using the best published international and national evidences and efficacy and safety of belimumab were synthesized using clinical data. A cost-effectiveness analysis was performed by a lifetime microsimulation model comparing belimumab to standard of care (SoC. Organizational and ethical implications were discussed. Results. Literature review showed that SLE affects 47 per 100,000 people for a total of 28,500 patients in Italy, 50% of whom are affected by active form of the disease despite SoC. These patients, if autoantibodies and anti-dsDNA positive with low complement, are eligible for belimumab. SLE determines work disability and a 2–5-fold increase in mortality. Belimumab with SoC may prevent 4,742 flares in three years being cost-effective with an incremental cost-effectiveness ratio of €32,859 per quality adjusted life year gained. From the organizational perspective, the development of clear and comprehensive clinical pathways is crucial. Conclusions. The assessment supports the use of belimumab into the SLE treatment paradigm in Italy.

    Spasmodic dysphonia voices form, in the same way as substitution voices, a particular category of dysphonia that seems not suited for a standardized basic multidimensional assessment protocol, like the one proposed by the European Laryngological Society. Thirty-three exhaustive analyses were performed on voices of 19 patients diagnosed with adductor spasmodic dysphonia (SD), before and after treatment with Botulinum toxin. The speech material consisted of 40 short sentences phonetically selected for constant voicing. Seven perceptual parameters (traditional and dedicated) were blindly rated by a panel of experienced clinicians. Nine acoustic measures (mainly based on voicing evidence and periodicity) were achieved by a special analysis program suited for strongly irregular signals and validated with synthesized deviant voices. Patients also filled in a VHI-questionnaire. Significant improvement is shown by all three approaches. The traditional GRB perceptual parameters appear to be adequate for these patients. Conversely, the special acoustic analysis program is successful in objectivating the improved regularity of vocal fold vibration: the basic jitter remains the most valuable parameter, when reliably quantified. The VHI is well suited for the voice-related quality of life. Nevertheless, when considering pre-therapy and post-therapy changes, the current study illustrates a complete lack of correlation between the perceptual, acoustic, and self-assessment dimensions. Assessment of SD-voices needs to be tridimensional.

  15. A review of the assessment and treatment of anger and aggression in offenders with intellectual disability.

    2002-05-01

    Rates of aggression amongst people with intellectual disability (ID) have been found to be high in studies conducted on several continents across a number of service settings. Aggression is the primary reason for people with ID to be admitted or re-admitted to institutional settings, and it is also the main reason for individuals in this client group to be prescribed behaviour-control drugs. Anger is a significant activator of aggression, but little is known about the emotional aspects of the lives of people with ID. There are many reasons for this, but a lack of reliable and validated assessment measures is chief among them. The present review found that very little work has been conducted to date concerning the development of robust tools for assessing anger and aggression in this population. A narrative review of interventions for reducing aggression and anger in people with ID showed that there is virtually no evidence to support the use of psychotropic medications. Research has shown that behavioural interventions can be effective; however, they are intrusive and have not been tested in naturalistic settings with higher-functioning clients and low-frequency aggression. More recently, cognitive-behavioural interventions have shown promise, but the mechanisms for effective change have yet to be delineated. Priority research questions relating to assessment, treatment and therapeutic skills in working with anger and aggression problems are offered by the present review.

    The aim of our study was to assess the efficacy and safety of medical treatment of non-viable first trimester pregnancy. We analyzed 50 cases of women diagnosed with non-viable first trimester pregnancy: missed abortion (79.6%) or anembryonic pregnancy (20.4%), who were admitted and treated at the First Clinic of Obstetrics and Gynecology Medical University of Warsaw, between June 2011 and February 2012. The diagnosis was made after two ultrasound examinations, performed at least one week apart. None of the patients manifested symptoms of imminent miscarriage. All women received medical treatment - misoprostol administered vaginally or in cases of excessive bleeding in the course of the procedure, sublingually - according to our own scheme. The patients were informed that any moment they could decide to discontinue medical treatment and ask for surgery Initially, 4 tablets containing misoprostol (800 mcg) were administered vaginally A control ultrasound examination was performed 6 hours later. If expulsion of the gestational sac was completed, the patient was discharged. If the gestational sac was still present in the uterus, an additional dose of misoprostol was administered: 4 tablets vaginally or if excessive bleeding occurred, 3 tablets (600 mcg) sublingually. Another ultrasound examination was performed after 6 hours from the second dose and the patient was discharged if the expulsion of the gestational sac was completed. If the procedure failed, it was repeated in the same manner the next day. D&C was performed in cases of excessive bleeding, failure of medical treatment after 48 hours, patient decision to discontinue medical treatment or suspected incomplete abortion after menstrual bleeding. For women who completed the medical treatment, control visits were scheduled 14 days after hospital discharge and after menstrual bleeding, if incomplete abortion was suspected. D&C was performed in 12% of patients because of failure of medical treatment after 48 hours

    BACKGROUND Nausea and vomiting in pregnancy (NVP) affects up to 85% of all women during pregnancy, but for the majority self-management suffices. For the remainder, symptoms are more severe and the most severe form of NVP - hyperemesis gravidarum (HG) - affects 0.3-1.0% of pregnant women. There is no widely accepted point at which NVP becomes HG. OBJECTIVES This study aimed to determine the relative clinical effectiveness and cost-effectiveness of treatments for NVP and HG. DATA SOURCES MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, PsycINFO, Commonwealth Agricultural Bureaux (CAB) Abstracts, Latin American and Caribbean Health Sciences Literature, Allied and Complementary Medicine Database, British Nursing Index, Science Citation Index, Social Sciences Citation Index, Scopus, Conference Proceedings Index, NHS Economic Evaluation Database, Health Economic Evaluations Database, China National Knowledge Infrastructure, Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effects were searched from inception to September 2014. References from studies and literature reviews identified were also examined. Obstetric Medicine was hand-searched, as were websites of relevant organisations. Costs came from NHS sources. REVIEW METHODS A systematic review of randomised and non-randomised controlled trials (RCTs) for effectiveness, and population-based case series for adverse events and fetal outcomes. Treatments: vitamins B6 and B12, ginger, acupressure/acupuncture, hypnotherapy, antiemetics, dopamine antagonists, 5-hydroxytryptamine receptor antagonists, intravenous (i.v.) fluids, corticosteroids, enteral and parenteral feeding or other novel treatment. Two reviewers extracted data and quality assessed studies. Results were narratively synthesised; planned meta-analysis was not possible due to heterogeneity and incomplete reporting.

    Background About 15% to 25% of people with diabetes will develop a foot ulcer. These wounds are often resistant to healing; therefore, people with diabetes experience lower limb amputation at about 20 times the rate of people without diabetes. If an ulcer does not heal with standard wound care, other therapeutic interventions are offered, one of which is hyperbaric oxygen therapy (HBOT). However, the effectiveness of this therapy is not clearly known. The objectives of this health technology assessment were to assess the safety, clinical effectiveness, and cost-effectiveness of standard wound care plus HBOT versus standard wound care alone for the treatment of diabetic foot ulcers. We also investigated the preferences and perspectives of people with diabetic foot ulcers through lived experience. Methods We performed a review of the clinical and economic literature for the effectiveness and cost-effectiveness of hyperbaric oxygen therapy, as well as the budget impact of HBOT from the perspective of the Ministry of Health and Long-Term Care. We assessed the quality of the body of clinical evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. To better understand the preferences, perspectives, and values of patients with diabetic foot ulcers and their experience with HBOT, we conducted interviews and administered an online survey. Results Seven randomized controlled trials and one nonrandomized controlled trial met the inclusion criteria. Comparing standard wound care plus HBOT with standard wound care alone, we found mixed results for major amputation rates (GRADE quality of evidence: low), a significant difference in favour of standard wound care plus HBOT on ulcers healed (GRADE quality of evidence: low), and no difference in terms of adverse events (GRADE quality of evidence: moderate). There is a large degree of uncertainty associated with the evaluation of the cost-effectiveness of standard wound

    2015-01-01

    Venous thromboembolism includes deep vein thrombosis and pulmonary embolism and is a serious medical condition that requires anticoagulation as part of treatment. Currently, standard therapy consists of parenteral anticoagulation followed by a vitamin K antagonist (VKA). The pharmacokinetic and pharmacodynamic profiles of the direct oral anticoagulants (DOACs) differ from VKAs, which overcome some of the limitations of VKAs and have practical implications on their use in clinical situations. Dabigatran is a prodrug that undergoes primarily renal elimination and does not affect cytochrome P450 enzymes. Assays to quantify the degree of anticoagulation and the therapeutic level of DOAC are either unavailable for routine clinical use or require specific calibration. Routine monitoring of DOACs is not recommended at this time. Dabigatran, rivaroxaban, and apixaban are DOACs that have been studied for treatment of venous thromboembolism. Clinical trials comparing DOACs with standard therapy have shown them to be non-inferior for acute and extended therapy. Each DOAC has a unique benefit and harm profile that should be considered prior to use. The distinguishing characteristics of dabigatran include a requirement of parenteral anticoagulation prior to acute treatment, clinical trial results comparing it with a VKA for extended treatment, association with upper gastrointestinal adverse events, and increased risk of gastrointestinal bleed. Rivaroxaban is the only DOAC that has once-daily dosing while apixaban is the only DOAC that has lower risk of overall, major, and gastrointestinal bleeding compared with VKA. A common drawback of DOACs is the lack of an available reversal agent. Clinical trials of reversal agents are ongoing and one application for approval has been submitted to the US Food and Drug Administration. Selection of a DOAC for acute and extended therapy requires a shared decision-making approach that includes a comprehensive assessment of the benefits and

    Full Text Available Current household solid waste treatment practices in most cities in Vietnam caused a great amount of direct greenhouse gas (GHG emissions. Available solid waste treatment technologies should be seriously taken  into consideration as a wedge of GHG mitigation in waste sector base on presently Vietnamese economic conditions. This study aim to evaluate the potential amount of GHG mitigation from current domestic solid waste treatment technologies in Vietnam including landfills and composting from various management scenarios. In oder to use Tier 2 model of IPCC 2006 for GHG estimation from landfills, an analysis on current household solid waste management system of the city was obtained by using material flow analysis approach. A case study in Hanoi, the capital city of Vietnam was carried out in this research. As a result, there was a reduced of over 70% of the amount of CH4 emissions and  up to 53% of total GHG saving (CO2-eq from avoiding organic waste to landfill. In addition, applying an energy recovery from LFG system to available landfills would lead to aproximately 75% of GHG saved compare to current emission of waste sector.Doi: http://dx.doi.org/10.12777/wastech.1.1.10-16Citation: Giang, H.M.,Luong, N.D., and Huong, L.T.M.2013.

    A study was conducted of nursing home residents with limited access to regular oral health care services to evaluate their oral health status, to perform an assessment of the need for oral treatment and to determine the possible predicting value of age, gender, care dependency and income level on their oral health status and treatment needs. Three experienced dentists collected clinical oral health data with a mobile dental unit in 23 nursing homes. Socio-demographic data were extracted from the residents' records in the nursing home. Besides the descriptive and bivariate analysis, a general linear mixed model analysis was also performed with the nursing home as random effect. The study sample consisted of 1,226 residents with a mean age of 83.9 years, of which 41.9% were edentulous. The mean D₃MFt in the dentate group was 24.5 and 77% needed extractions or fillings. In the group of residents wearing removable dentures, 36.9% needed repair, rebasing or renewal of the denture. The mixed model analysis demonstrated that with each year a resident gets older, the oral health outcomes get worse and that men have worse oral health and higher treatment needs than women. However, the level of income and care dependency had a less extensive role in predicting the oral health outcomes. The nursing home residents presented a poor overall oral health status and high dental and prosthetic treatment needs. Gender and age were important predicting variables for the oral health outcomes.

    To report hepatic arterial-related complications encountered during planning and treatment angiograms for radioembolization and understand any potential-associated risk factors. 518 mapping or treatment angiograms for 180 patients with primary or metastatic disease to the liver treated by Yttrium-90 radioembolization between 2/2010 and 12/2015 were retrospectively reviewed. Intra-procedural complications were recorded per SIR guidelines. Patient demographics, indication for treatment, prior exposure to chemotherapeutic agents, operator experience, and disease burden were reviewed. Technical variables including type of radioembolic (glass vs. resin microspheres), indication for angiography (mapping vs. treatment), variant anatomy, and attempts at coil embolization were also assessed. Thirteen (13/518, 2.5%) arterial-related complications occurred in 13 patients. All but two complications resulted during transcatheter coil embolization to prevent non-target embolization. Complications included coil migration (n = 6), arterial dissection (n = 2), focal vessel perforation (n = 2), arterial thrombus (n = 2), and vasospasm prohibiting further arterial sub-selection (n = 1). Transarterial coiling was identified as a significant risk factor of complications on both univariate and multivariate regression analysis (odds ratio 7.8, P = 0.004). Usage of resin microspheres was also a significant risk factor (odds ratio 9.5, P = 0.042). No other technical parameters or pre-procedural variables were significant after adjusting for confounding on multivariate analysis (P > 0.05). Intra-procedural hepatic arterial complications encountered during radioembolization were infrequent but occurred mainly during coil embolization to prevent non-target delivery to extra-hepatic arteries.

    Full Text Available Background: In the last years, there has been an increase in cases of latent and late neurosyphilis. Due to the wide implementation of antibiotics, there is a significant reduction in sensitivity of serological and general clinical tests used for diagnosis of this disease. The situations are not uncommon when it is not possible to exclude or confirm the invasion of Treponema pallidum into the nervous system structures. Absence of objective diagnostic criteria for neurosyphilis hints the timely administration of an adequate treatment aimed at prevention of an irreversible derangement of the nervous system and to the patient death. Aim: To search for new diagnostic symptoms of an injury to the brain structures caused by Treponema pallidum in patients with previous syphilis, based on a new technology of assessment of solid phase structures of cerebrospinal fluid. Materials and methods: One hundred and thirty one patient that had been treated for various forms of syphilis were recruited to this study. In addition to generally accepted clinical and laboratory assessments, including various serological methods, all patients underwent clinical and serological assessment of cerebrospinal fluid (CSF. According to the results of this assessment, all patients were categorized into three groups. Group 1 (n=27 consisted of patients with early asymptomatic neurosyphilis, group 2 (n=46, with late meningovascular neurosyphilis, group  3 (n=58, those without diagnosed neurosyphilis but with strong positive serum tests, negative CSF serology and negative VDRL test. An innovative method of marginal dehydration of biological fluids was used. The method is included into the Lithos-system diagnostic technology and allows for evaluation of the structures of CSF systems “lipid – water”, “lipid – protein – water” after their transition from liquid crystal phase into a  solid phase. These structures called anisomorphons are seen only at polarized

    Full Text Available Background: Periodontitis is multifactorial in nature. The various determinants of periodontal disease are age, sex, race, socioeconomic status, and risk factors including tobacco usage and oral hygiene status. However, there is inconsistent epidemiological data on the periodontal status of subjects living in high-fluoride areas. The aim of the study was to investigate the effect of dental fluorosis on the periodontal status using community periodontal index of treatment needs (CPITN, as a clinical study. The purpose of this study is to determine the periodontal status using CPITN index in a population aged between 15 and 74 years residing in the high-fluoride areas of Davangere district. The possible reasons for the susceptibility of this population to periodontal disease are discussed. Materials and Methods: 1029 subjects, aged between 15 and 74 years suffering from dental fluorosis were assessed for their periodontal status. Clinical parameters recorded were OHI-S to assess the oral hygiene status, Jackson′s fluorosis index to assess the degree of fluorosis and CPITN index to assess the periodontal status where treatment need was excluded. Results: Gingivitis and periodontitis were more common in females (65.9% and 32.8%, respectively than in males (75.1% and 24.2%, respectively. Periodontitis was significantly more common in females. As the age advanced from 15 to 55 years and above, gingivitis reduced from 81.0 to 42.9% and periodontitis increased steadily from 18.0 to 57.1%, which was significant. Periodontitis was high in subjects with poor oral hygiene (81.3%, compared to those with good oral hygiene (14.5%, which was significant. As the degree of fluorosis increased, severity of gingivitis reduced and periodontitis increased, i.e., with A degree fluorosis, gingivitis was 89.4% and periodontitis 8.5%, but with F degree fluorosis the former was 64% and the latter 35.8%, which was statistically significant. Conclusion: The results

  9. Medical and health economic assessment of radiosurgery for the treatment of brain metastasis

    2009-03-01

    Full Text Available Background: Radiotherapy for patients suffering from malignant neoplasms has developed greatly during the past decades. Stereotactic radiosurgery (SRS is one important radiotherapeutic option which is defined by a single and highly focussed application of radiation during a specified time interval. One of its important indications is the treatment of brain metastases. Objectives: The objective of this HTA is to summarise the current literature concerning the treatment of brain metastasis and to compare SRS as a single or additional treatment option to alternative treatment options with regard to their medical effectiveness/efficacy, safety and cost-effectiveness as well as their ethical, social and legal implications. Methods: A structured search and hand search of identified literature are performed from January 2002 through August 2007 to identify relevant publications published in English or German. Studies targeting patients with single or multiple brain metastases are included. The methodological quality of included studies is assessed according to quality criteria, based on the criteria of evidence based medicine. Results: Of 1,495 publications 15 medical studies meet the inclusion criteria. Overall study quality is limited and with the exception of two randomized controlleed trials (RCT and two meta-analyses only historical cohort studies are identified. Reported outcome measures are highly variable between studies. Studies with high methodological quality provide evidence, that whole-brain radiotherapy (WBRT in addition to SRS and SRS in addition to WBRT is associated with improved local tumour control rates and neurological function. However, only in patients with single brain metastasis, RPA-class 1 (RPA = Recursive partitioning analysis and certain primary tumour entities, this combination of SRS and WBRT is associated with superior survival compared to WBRT alone. Studies report no significant differences in adverse events between

    The aim of the study was to evaluate, in a sample of young asthmatics in Italy, the current practice in assessment and treatment of asthma after the publication of guidelines. Young soldiers who declared bronchial asthma at the beginning of the compulsory military service were evaluated. One-hundred and thirty-eight subjects with confirmed asthma were selected. Sixty-seven subjects (48.5%) had had at last one spirometry, and only one subject had underwent peak flow monitoring at home; most of the subjects (96.8%) had had prick tests. More of the 50% of the subjects with bronchial obstruction or with severe bronchial hyperresponsiveness, with clinical moderate or severe asthma, had used only bronchodilators or no therapy at all in the preceding year. In this sample of young asthmatics, the lung function tests were still underutilized for the diagnosis and follow-up of bronchial asthma; moreover, the inhaled anti-inflammatory drugs were still underutilized.

    Aim of this study was to evaluate the ecotoxicity of municipal sewage sludge conditioned with polyelectrolytes, taken from selected sewage treatment plant. Using the bioindication analysis overall toxicity was assessed, which allows to know the total toxicity of all the harmful substances contained in sewage sludge, in many cases acting synergistically. To prepare a sample of sludge for the basic test, all analyses were performed with a ratio of liquid to solid of 10:1 (water extract). Daphnia pulex biological screening test was used. A dilution series of an water extract of sludge were prepared to include within its scope the lowest concentration that causes 100% effect and the highest producing less than 10% of the effect within a specified range of the assay. The results of the test were read after 24 and 48 hours. Based on the research and analysis of test results it proved that the sewage sludge conditioned with polyelectrolytes exhibit the characteristics of eco-toxic.

    This is the official guideline endorsed by the specialty associations involved in the care of head and neck cancer patients in the UK. This paper provides recommendations on the pre-treatment clinical assessment of patients presenting with head and neck cancer. Recommendations • Comorbidity data should be collected as it is important in the analysis of survival, quality of life and functional outcomes after treatment as well as for comparing results of different treatment regimens and different centres. (R) • Patients with hypertension of over 180/110 or associated target organ damage, should have antihypertensive medication started pre-operatively as per British Hypertension Society guidelines. (R) • Rapidly correcting pre-operative hypertension with beta blockade appears to cause higher mortality due to stroke and hypotension and should not be used. (R) • Patients with poorly controlled or unstable ischaemic heart disease should be referred for cardiology assessment pre-operatively. (G) • Patients within one year of drug eluting stents should be discussed with the cardiologist who was responsible for their percutaneous coronary intervention pre-operatively with regard to cessation of antiplatelet medication due to risk of stent thrombosis. (G) • Patients with multiple recent stents should be managed in a centre with access to interventional cardiology. (G) • Surgery after myocardial infarction should be delayed if possible to reduce mortality risk. (R) • Patients with critical aortic stenosis (AS) should be considered for pre-operative intervention. (G) • Clopidogrel should be discontinued 7 days pre-operatively; warfarin should be discontinued 5 days pre-operatively. (R) • Patients with thromboembolic disease or artificial heart valves require heparin therapy to bridge peri-operative warfarin cessation, this should start 2 days after last warfarin dose. (R) • Cardiac drugs other than angotensin-converting enzyme inhibitors and angiotensin

    Efficient and reliable assessments of cognitive treatment effects are essential for the comparative evaluation of procognitive effects of pharmacologic therapies. Yet, no studies have addressed the sensitivity and efficiency with which neurocognitive batteries evaluate cognitive abilities before and after treatment. Participants were primarily first episode schizophrenia patients who completed baseline (n = 367) and 12-week (n = 219) assessments with the BACS (Brief Assessment of Cognition in Schizophrenia) and CATIE (Clinical Antipsychotic Trials of Intervention Effectiveness) neuropsychological batteries in a clinical trial comparing olanzapine, quetiapine, and risperidone. Exploratory factor analysis revealed that performance on both batteries was characterized by a single factor of generalized cognitive deficit for both baseline performance and cognitive change after treatment. Both batteries estimated similar levels of change following treatment, although the BACS battery required half the administration time. Because a unitary factor characterized baseline cognitive abilities in early psychosis as well as cognitive change after treatment with atypical antipsychotic medications, short batteries such as the BACS may efficiently provide sufficient assessment of procognitive treatment effects with antipsychotic medications. Assessment of cognitive effects of adjunctive therapies targeting specific cognitive domains or impairments may require more extensive testing of the domains targeted to maximize sensitivity for detecting specific predicted cognitive outcomes.

    Low back pain is one of the most frequent reasons for medical appointments. Surgical treatment is widely controversial, and new surgical techniques and treatment modalities have been developed within the last decade. Treatment for low back pain should be evidence-based through systematic reviews and meta-analysis. Thus, the quality of these reviews is sometimes put into question as methodological mistakes are frequently seen. The aim of this study was to gather all systematic reviews for the surgical treatment of low back pain and analyze their outcomes, quality, and conclusion. This is an overview of systematic reviews. The outcome measures were the AMSTAR (A MeaSurement Tool to Assess systematic Reviews) score, PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement, and conclusion supported by descriptive statistics. A literature search for systematic reviews containing low back pain surgical treatment was conducted through different medical databases. Two investigators independently assessed all titles and abstracts for inclusion. Studies should have at least one surgical procedure as an intervention. Diagnoses were categorized as lumbar disc herniation, spondylolisthesis, stenosis, facet joint syndrome, and degenerative disc disease. Quality was assessed through the PRISMA and AMSTAR questionnaires. Study quality related to its PRISMA or AMSTAR score percentage was rated as very poor (90%). Articles were considered conclusive if they had a conclusion for their primary outcome supported by descriptive statistical evidence. This study was funded exclusively by the authors' own resources. None of the authors have any potential conflict of interest to declare. Overall, there were 40 systematic reviews included. According to AMSTAR and PRISMA scores, 5% to 7.5% of the systematic reviews were rated as excellent and most of them were rated as a fair review. AMSTAR indicated that 22.5% of the reviews have very poor quality, whereas PRISMA

    This paper presents a new methodology to assess the risk of water effluents from waste-water treatment plants (WWTPs) based on fuzzy logic, a well-known theory to deal with uncertainty, especially in the environmental field where data are often lacking. The method has been tested using the effluent's pollution data coming from 22 waste-water treatment plants (WWTPs) located in Catalonia (NE Spain). Thirty-eight pollutants were analyzed along three campaigns performed yearly from 2008 to 2010. Whereas 9 compounds have been detected in more than 70% of the samples analyzed, 7 compounds have been found at levels equal or higher than the river Environmental Quality Standards set by the Water Framework Directive. Upon combination of both criteria (presence and concentration), compounds of greatest environmental concern in the WWTP studied are nickel, the herbicide diuron, and the endocrine disruptors nonyl and octylphenol. It is remarkable the low variability of the pollutant concentration just differing for the case of nickel and zinc. These low values of exposure together with other pollutants' characteristics provide a medium or low risk assessment for all the WWTPs. The results of this new method have been compared with COMMPS procedure, a solid method developed in the context of the Water Framework Directive, and they show that the fuzzy model is more conservative than COMMPS. This is due to different reasons: the fuzzy model takes into account the persistence of chemical compounds whereas COMMPS does not; the fuzzy model includes the weights provided by an expert group inquired in previous works and also considers the uncertainty of the environmental data, avoiding the crisp values and offering a range of overlapping between the different fuzzy sets. However, the results even if being more conservative with fuzzy logic, are in good agreement with a solid methodology such as the COMMPS procedure.

    High levels of psychiatric morbidity in prisoners have important implications for services. Assessing Needs for Psychiatric Treatment in Prisoners is an evaluation of representative samples of prisoners in a male and a female prison in London. This paper reports on the prevalence of mental disorders. In a companion paper, we describe how this translates into mental health treatment needs and the extent to which they have been met. Prisoners were randomly sampled in a sequential procedure based on the Local Inmate Data System. We interviewed roughly equal numbers from the following groups: male remand; male sentenced prisoners (Pentonville prison); and female remand; female sentenced prisoners (Holloway prison). Structured assessments were made of psychosis, common mental disorders, PTSD, personality disorder and substance abuse. We interviewed 197 male and 171 female prisoners. Psychiatric morbidity in male and female, sentenced and remand prisoners far exceeded in prevalence and severity than in equivalent general population surveys. In particular, 12% met criteria for psychosis; 53.8% for depressive disorders; 26.8% for anxiety disorders; 33.1% were dependent on alcohol and 57.1% on illegal drugs; 34.2% had some form of personality disorder; and 69.1% had two disorders or more. Moreover, in the year before imprisonment, 25.3% had used mental health services. These rates of mental ill-health and their similarity in remand and sentenced prisoners indicate that diversion of people with mental health problems from the prison arm of the criminal justice system remains inadequate, with serious consequences for well-being and recidivism.

    Background: Though clinical guidelines for assessment and treatment of chronic subjective tinnitus do exist, a comprehensive review of those guidelines has not been performed. The objective of this review was to identify current clinical guidelines, and compare their recommendations for the assessment and treatment of subjective tinnitus in adults. Method: We systematically searched a range of sources for clinical guidelines (as defined by the Institute of Medicine, United States) for the assessment and/or treatment of subjective tinnitus in adults. No restrictions on language or year of publication were applied to guidelines. Results: Clinical guidelines from Denmark, Germany, Sweden, The Netherlands, and the United States were included in the review. There was a high level of consistency across the guidelines with regard to recommendations for audiometric assessment, physical examination, use of a validated questionnaire(s) to assess tinnitus related distress, and referral to a psychologist when required. Cognitive behavioral treatment for tinnitus related distress, use of hearing aids in instances of hearing loss and recommendations against the use of medicines were consistent across the included guidelines. Differences between the guidelines centered on the use of imaging in assessment procedures and sound therapy as a form of treatment for tinnitus distress respectively. Conclusion: Given the level of commonality across tinnitus guidelines from different countries the development of a European guideline for the assessment and treatment of subjective tinnitus in adults seems feasible. This guideline would have the potential to benefit the large number of clinicians in countries where clinical guidelines do not yet exist, and would support standardization of treatment for patients across Europe.

    Perioperative monitoring of coagulation is vital to assess bleeding risks, diagnose deficiencies associated with hemorrhage, and guide hemostatic therapy in major surgical procedures, such as liver transplantation. Routine static tests demand long turnaround time and do not assess platelet function; they are determined on plasma at a standard temperature of 37°C; hence these tests are ill-suited for intraoperative use. In contrast, methods which evaluate the viscoelastic properties of whole blood, such as thromboelastogram and rotational thromboelastometry, provide rapid qualitative coagulation assessment and appropriate guidance for transfusion therapy. These are promising tools for the assessment and treatment of hyper- and hypocoagulable states associated with bleeding in liver transplantation. When combined with traditional tests and objective assessment of the surgical field, this information provides ideal guidance for transfusion strategies, with potential improvement of patient outcomes. RESUMO A monitorização perioperatória da coagulação é fundamental para estimar o risco de sangramento, diagnosticar deficiências causadoras de hemorragia e guiar terapias hemostáticas durante procedimentos cirúrgicos de grande porte, como o transplante hepático. Os testes estáticos, comumente usados na prática clínica, são insatisfatórios no intraoperatório, pois demandam tempo e não avaliam a função plaquetária; são determinados no plasma e realizados em temperatura padrão de 37°C. Os métodos que avaliam as propriedades viscoelásticas do sangue total, como o tromboelastograma e a tromboelastometria rotacional, podem suprir as deficiências dos testes estáticos tradicionais, uma vez que permitem avaliar a coagulação de forma rápida e qualitativa, guiando a terapia transfusional de forma adequada. A tromboelastometria rotacional mostrou-se promissora na avaliação e no tratamento de estados de hipercoagulação e hipocoagulação, associados a

    A Life Cycle Assessment (LCA) of a municipal wastewater treatment plant (WWTP) was conducted to illustrate the effect of an emission inventory data collection scheme on the outcomes of an environmental impact assessment. Due to their burden in respect to data collection, LCAs often rely heavily on existing emission and operational data, which are gathered under either compulsory monitoring or reporting requirements under law. In this study, an LCA was conducted using three input data sources: Information compiled under compulsory disclosure requirements (the European Pollutant Release and Transfer Registry), compliance with national discharge limits, and a state-of-the-art emission data collection scheme conducted at the same WWTP. Parameter uncertainty for each collection scheme was assessed through Monte Carlo simulation. The comparison of the results confirmed that LCA results depend heavily on input data coverage. Due to the threshold on reporting value, the E-PRTR did not capture the impact for particulate matter emission, terrestrial acidification, or terrestrial eutrophication. While the current practice can capture more than 90% of non-carcinogenic human toxicity and marine eutrophication, an LCA based on the data collection scheme underestimates impact potential due to limitations of substance coverage. Besides differences between data collection schemes, the results showed that 3-13,500% of the impacts came from background systems, such as from the provisioning of fuel, electricity, and chemicals, which do not need to be disclosed currently under E-PRTR. The incidental release of pollutants was also assessed by employing a scenario-based approach, the results of which demonstrated that these non-routine emissions could increase overall WWTP greenhouse gas emissions by between 113 and 210%. Overall, current data collection schemes have the potential to provide standardized data collection and form the basis for a sound environmental impact assessment, but

    Orthodontics in China has developed rapidly, but there is no standard index of treatment outcomes. We assessed the validity of the American Board of Orthodontics Objective Grading System (ABO-OGS) for the classification of treatment outcomes in Chinese patients. We randomly selected 108 patients who completed treatment between July 2005 and September 2008 in 6 orthodontic treatment centers across China. Sixty-nine experienced Chinese orthodontists made subjective assessments of the end-of-treatment casts for each patient. Three examiners then used the ABO-OGS to measure the casts. Pearson correlation analysis and receiver operating characteristic curve analysis were conducted to evaluate the correspondence between the ABO-OGS cast measurements and the orthodontists' subjective assessments. The average subjective grading scores were highly correlated with the ABO-OGS scores (r = 0.7042). Four of the 7 study cast components of the ABO-OGS score-occlusal relationship, overjet, interproximal contact, and alignment-were statistically significantly correlated with the judges' subjective assessments. Together, these 4 accounted for 58% of the variability in the average subjective grading scores. The ABO-OGS cutoff score for cases that the judges deemed satisfactory was 16 points; the corresponding cutoff score for cases that the judges considered acceptable was 21 points. The ABO-OGS is a valid index for the assessment of treatment outcomes in Chinese patients. By comparing the objective scores on this modification of the ABO-OGS with the mean subjective assessment of a panel of highly qualified Chinese orthodontists, a cutoff point for satisfactory treatment outcome was defined as 16 points or fewer, with scores of 16 to 21 points denoting less than satisfactory but still acceptable treatment. Cases that scored greater than 21 points were considered unacceptable. Copyright © 2013 American Association of Orthodontists. Published by Mosby, Inc. All rights reserved.

    The selection of the most appropriate wastewater treatment (WWT) technology is a complex problem since many alternatives are available and many criteria are involved in the decision-making process. To deal with this challenge, the analytic network process (ANP) is applied for the first time to rank a set of seven WWT technology set-ups for secondary treatment in small communities. A major advantage of ANP is that it incorporates interdependent relationships between elements. Results illustrated that extensive technologies, constructed wetlands and pond systems are the most preferred alternatives by WWT experts. The sensitivity analysis performed verified that the ranking of WWT alternatives is very stable since constructed wetlands are almost always placed in the first position. This paper showed that ANP analysis is suitable to deal with complex decision-making problems, such as the selection of the most appropriate WWT system contributing to better understand the multiple interdependences among elements involved in the assessment.

    The environmental performance of mechanical biological pre-treatment (MBT) of Municipal Solid Waste is quantified using Life Cycle Assessment (LCA), considering one of the 57 French plants currently in operation as a case study. The inventory is mostly based on plant-specific data, extrapolated from on-site measurements regarding mechanical and biological operations (including anaerobic digestion and composting of digestate). The combined treatment of 46,929 tonnes of residual Municipal Solid Waste and 12,158 tonnes of source-sorted biowaste (as treated in 2010 at the plant) generates 24,550 tonnes CO2-eq as an impact on climate change, 69,943kg SO2-eq on terrestrial acidification and 19,929kg NMVOC-eq on photochemical oxidant formation, in a life-cycle perspective. On the contrary MBT induces environmental benefits in terms of fossil resource depletion, human toxicity (carcinogenic) and ecotoxicity. The results firstly highlight the relatively large contribution of some pollutants, such as CH4, emitted at the plant and yet sometimes neglected in the LCA of waste MBT. Moreover this study identifies 4 plant-specific operation conditions which drive the environmental impact potentials induced by MBT: the conditions of degradation of the fermentable fraction, the collection of gaseous flows emitted from biological operations, the abatement of collected pollutants and NOx emissions from biogas combustion. Finally the results underline the relatively large influence of the operations downstream the plant (in particular residuals incineration) on the environmental performance of waste MBT.

    The estrogenic potency of a wastewater treatment plant (WWTP) was evaluated using chemical and biological analyses,which showed that after the station treatment processes some of the selected endocrine disruptor compounds (EDCs) were still present in the treated effluent (e.g.,bisphenol A,alkylphenols,estrone).Thus,the most common endocrine EDCs were identified and quantified and the overall estrogenicity of the treated effluent assessed by integrating the results.Male goldfish (Carassius auratus) were used as biological indicators in a 28-day experiment.Viteliogenin (Vtg),gonadosomatic and hepatosomatic indices,steroids (17β-estradiol and 11-ketotestosterone) and histopathology were biomarkers used in fish to evaluate WWTP treated effluent estrogenicity,in combination with instrumental analyses.The results showed a significant increase (P<0.01) in plasma and liver Vtg,which were significantly correlated (r = 0.66;P<0.01).The gonadosmatic index was significantly (P<0.01) reduced in exposed fish.The steroid analyses revealed significant elevations in 17β-estradiol and depressed 11-ketotestosterone concentrations.The histological examinations show changes in exposed fish gonads,such as regressed testes and in some cases (43% to 75%) the development of ovo-testis in fish exposed to 50% and 100% treated effluent.

    Full Text Available Heavy metals are present in low concentrations in reservoirs, but seasonal anthropogenic activities usually elevate the concentrations to a level that could become a health hazard. The dry season concentrations of cadmium, copper, iron, lead, mercury, nickel and zinc were assessed from three sites for 12 weeks in Oyun reservoir, Offa, Nigeria. Triplicate surface water samples were collected and analysed using atomic absorption spectrophotometry. The trend in the level of concentrations in the three sites is site C > B > A, while the trend in the levels of the concentrations in the reservoir is Ni > Fe > Zn > Pb > Cd > Cu > Hg. Ni, Cd, Pb and Hg were found to be higher than the WHO guidelines for the metals in drinking water. The high concentration of these metals was from anthropogenic watershed run-off of industrial effluents, domestic sewages and agricultural materials into the reservoir coming from several human activities such as washing, bathing, fish smoking, especially in site C. The health effects of high concentration of these metals in the reservoir were highlighted. Methods for the treatment and removal of the heavy metals from the reservoir during water purification such as active carbon adsorption, coagulation-flocculation, oxidation-filtration, softening treatment and reverse osmosis process were highlighted. Other methods that could be used include phytoremediation, rhizofiltration, bisorption and bioremediation. Watershed best management practices (BMP remains the best solution to reduce the intrusion of the heavy metals from the watershed into the reservoir.

    Anaerobic digestion (AD) is being established as a standard technology to recover some of the energy contained in the sludge in wastewater treatment plants (WWTPs) as biogas, allowing an economy in electricity and heating and a decrease in climate gas emission. The purpose of this study was to quantify the contributions to the total environmental impact of the plant using life cycle assessment methodology. In this work, data from real operation during 2012 of a municipal WWTP were utilized as the basis to determine the impact of including AD in the process. The climate change human health was the most important impact category when AD was included in the treatment (Scenario 1), especially due to fossil carbon dioxide emissions. Without AD (Scenario 2), increased emissions of greenhouse gases, mostly derived from the use of electricity, provoked a rise in the climate change categories. Biogas utilization was able to provide 47% of the energy required in the WWTP in Scenario 1. Results obtained make Scenario 1 the better environmental choice by far, mainly due to the use of the digested sludge as fertilizer.

    2010-05-01

    Full Text Available The aim of this study was to assess the wastewater discharge impact from the University of Lagos campus treatment plant on the lagoon system . In order to achieve this objective water samples were collected from nine sites and analyzed for different wastewater quality variables. The field survey was carried out between July and November in order to capture both the wet and dry seasons. Average removal efficiencies of measured parameters from treated effluents are 26% for Total Dissolved Solids (TDS, 73% for Biological Oxygen Demand (BOD, 65.8% for Chemical Oxygen Demand (COD and 72% for Total Nitrogen (Total N for the wet season campaign. During the dry season average rem oval efficiencies of measured parameters are 54% for TDS, 54% for BOD, 39% for COD and 42% for Total N. These values are lower than values obtained for the wet season except for TDS. Most parameters in effluents exceeded the National Environmental Protection Regulations, Effluent Limitation standards for discharge into river bodies. Average concentrations of TDS, BOD and COD in lagoon water show higher concentrations than in the treated effluent and are above the regulatory requirements. The research recommends further study on the possible influence of water dynamics and sampling methods on water quality of the lagoon. The overall results from this research conclude that the lagoon is being polluted by effluents discharge from the university treatment plant thereby exposing the health of local residents who use it for recreation and for food production purposes.

    Owing to its proven toxicity and mutagenicity, arsenic is regarded a principal pollutant in water used for drinking. The objective of this study was the toxicological and chemical evaluation of groundwater samples obtained from arsenic enriched drinking water wells before and after electrochemical and ozone-UV-H2O2-based advanced oxidation processes (EAOP). For this purpose, acute toxicity test with Daphnia magna and chronic toxicity test with Lemna minor L. were employed as well as in vitro bioassays using human peripheral blood lymphocytes (HPBLs). Several oxidative stress parameters were estimated in L.minor. Physicochemical analysis showed that EAOP treatment was highly efficient in arsenic but also in ammonia and organic compound removal from contaminated groundwater. Untreated groundwater caused only slight toxicity to HPBLs and D. magna in acute experiments. However, 7-day exposure of L. minor to raw groundwater elicited genotoxicity, a significant growth inhibition and oxidative stress injury. The observed genotoxicity and toxicity of raw groundwater samples was almost completely eliminated by EAOP treatment. Generally, the results obtained with L. minor were in agreement with those obtained in the chemical analysis suggesting the sensitivity of the model organism in monitoring of arsenic-contaminated groundwater. In parallel to chemical analysis, the implementation of chronic toxicity bioassays in a battery is recommended in the assessment of the toxic and genotoxic potential of such complex mixtures.

    Protein-energy malnutrition (PEM) is a significant cause of morbidity and mortality for patients receiving maintenance hemodialysis. Minimal study has evaluated therapeutic options for and biochemical marker assessment of pediatric patient PEM. In 2001, we expanded the indications for intradialytic parenteral nutrition (IDPN) treatment of PEM to all maintenance hemodialysis patients, regardless of etiology, who had a >10% weight loss and were at less than the 90th percentile of ideal body weight. Nine patients received thrice weekly IDPN from 3 to 22 months with minimal side effects. Six patients had weight and body mass index increase, 1 patient stopped losing weight, and 2 patients continued to lose weight during the initial 5 months of IDPN therapy. Cohort subanalysis showed that all patients with organic PEM responded to IDPN therapy, whereas patients with psychosocial causes of PEM did not. The normalized protein catabolic rate increased significantly for patients whose condition responded to IDPN therapy, whereas serum albumin did not change. The current study suggests that IDPN is effective treatment of organic causes of PEM in pediatric patients receiving maintenance hemodialysis and that normalized protein catabolic rate may be superior to serum albumin as a marker of nutrition status. The observation that IDPN was not sufficient to reverse PEM in patients with psychosocial PEM causes should direct caregivers to address the relevant underlying causes as well as to provide intensive nutrition therapy.

    Interest in reuse of process water from the food industry has reinforced the importance of controlling and monitoring the effectiveness and reliability of treatment systems regarding removal of organic matter and microorganisms. The ability of adenosine triphosphate bioluminescence, conductivity, turbidometry, absorbance, and multichannel fluorescence spectroscopy for indirectly monitoring the integrity of a reverse osmosis membrane when treating process water recovered from peeling in a shrimp processing line was evaluated. This study demonstrated that reverse osmosis was capable of removing bacteria (ca. 7 log CFU ml(-1)) to the levels required by the regulatory authorities for water recycling within the same food unit operation. Adenosine triphosphate and turbidometry showed a higher sensitivity for detecting compromising conditions at the treatment system (0.1% concentration of feed in permeate) and a better correlation with the aerobic count at lower levels than the other methods investigated. The sensitivity for assessing membrane integrity of conductivity and multichannel fluorescence was 1% of feed in permeate. Impact of feed variations was best leveled out in the permeates for turbidity measurements. Multichannel fluorescence spectroscopy may require laborious calibration procedures and expertise regarding data analysis and interpretation of results, which are not always available in food industries. Absorbance did not respond to changes in membrane integrity and was not well correlated to the aerobic count because of the poor sensitivity of this method for these purposes.

    Caries remains one of the top three most common infectious diseases in the world today. Although caries prevalence decreased markedly in children and in adults up to age 40 between 1975 and 2000, the overall risk for caries in older age groups (45 to 64, 65 to 84, and > 85 years of age) has not decreased appreciably. In fact, the risk for caries in individuals 70 years of age and older has increased. The increase in restorative work needed between 1990 and 2030 will be highest in adults over the age of 44 years. Root caries prevalence and the number of restored teeth will be greatest in the elderly population. Approximately 30% of individuals over the age of 65 will have no permanent teeth. It is also apparent that additional caries risk factors are associated with a significant proportion of the older population, including reduced saliva flow, inadequate oral hygiene, frequent sugar intake, Asian ethnicity, and the presence of partial dentures. The principles of modern caries management focus on risk assessment, risk reduction, monitoring noncavitated carious lesions, and the assignment of specific treatment options according to risk. Because a relatively high proportion of elderly patients will remain at high risk for caries, therapeutic regimens for managing caries as an infectious disease must focus on the use of antibacterial treatment; high-fluoride dentifrices; supplementary low-dose, high-frequency fluoride rinses; patient education; and shorter recall intervals.

    Full Text Available Partial thickness burns can advance to full thickness after initial injury due to inadequate tissue perfusion and increased production of inflammatory cytokines, which has been referred to as burn wound progression. In previous work, we demonstrated that a keratin biomaterial hydrogel appeared to reduce burn wound progression. In the present study, we tested the hypothesis that a modified keratin hydrogel could reduce burn wound progression and speed healing. Standardized burn wounds were created in Yorkshire swine and treated within 30 minutes with keratin hydrogel (modified and unmodified, collagen hydrogel, or silver sulfadiazine (SSD. Digital images of each wound were taken for area measurements immediately prior to cleaning and dressing changes. Wound tissue was collected and assessed histologically at several time points. Wound area showed a significant difference between hydrogels and SSD groups, and rates of reepithelialization at early time points showed an increase when keratin treatment was used compared to both collagen and SSD. A linear regression model predicted a time to wound closure of approximately 25 days for keratin hydrogel while SSD treatment required 35 days. There appeared to be no measurable differences between the modified and unmodified formulations of keratin hydrogels.

    Hypertension Canada provides annually updated, evidence-based guidelines for the diagnosis, assessment, prevention, and treatment of hypertension. This year, we introduce 10 new guidelines. Three previous guidelines have been revised and 5 have been removed. Previous age and frailty distinctions have been removed as considerations for when to initiate antihypertensive therapy. In the presence of macrovascular target organ damage, or in those with independent cardiovascular risk factors, antihypertensive therapy should be considered for all individuals with elevated average systolic nonautomated office blood pressure (non-AOBP) readings ≥ 140 mm Hg. For individuals with diastolic hypertension (with or without systolic hypertension), fixed-dose single-pill combinations are now recommended as an initial treatment option. Preference is given to pills containing an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in combination with either a calcium channel blocker or diuretic. Whenever a diuretic is selected as monotherapy, longer-acting agents are preferred. In patients with established ischemic heart disease, caution should be exercised in lowering diastolic non-AOBP to ≤ 60 mm Hg, especially in the presence of left ventricular hypertrophy. After a hemorrhagic stroke, in the first 24 hours, systolic non-AOBP lowering to hypertension arising from fibromuscular dysplasia. The specific evidence and rationale underlying each of these guidelines are discussed. Copyright © 2017 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

    Full Text Available Abstract Aim We evaluated the use of computerized quantification of wheezing and crackles compared to a clinical score in assessing the effect of inhaled albuterol or inhaled epinephrine in infants with RSV bronchiolitis. Methods Computerized lung sounds analysis with quantification of wheezing and crackles and a clinical score were used during a double blind, randomized, controlled nebulized treatment pilot study. Infants were randomized to receive a single dose of 1 mgr nebulized l-epinephrine or 2.5 mgr nebulized albuterol. Computerized quantification of wheezing and crackles (PulmoTrack® and a clinical score were performed prior to, 10 minutes post and 30 minutes post treatment. Results were analyzed with Student's t-test for independent samples, Mann-Whitney U test and Wilcoxon test. Results 15 children received albuterol, 12 received epinephrine. The groups were identical at baseline. Satisfactory lung sounds recording and analysis was achieved in all subjects. There was no significant change in objective quantification of wheezes and crackles or in the total clinical scores either within the groups or between the groups. There was also no difference in oxygen saturation and respiratory distress. Conclusion Computerized lung sound analysis is feasible in young infants with RSV bronchiolitis and provides a non-invasive, quantitative measure of wheezing and crackles in these infants.

    Life cycle assessment (LCA) is a technique to quantify the impacts associated with a product, service or process from cradle-to-grave perspective. Within the field of wastewater treatment (WWT) LCA was first applied in the 1990s. In the pursuit of more environmentally sustainable WWT, it is clear that LCA is a valuable tool to elucidate the broader environmental impacts of design and operation decisions. With growing interest from utilities, practitioners, and researchers in the use of LCA in WWT systems, it is important to make a review of what has been achieved and describe the challenges for the forthcoming years. This work presents a comprehensive review of 45 papers dealing with WWT and LCA. The analysis of the papers showed that within the constraints of the ISO standards, there is variability in the definition of the functional unit and the system boundaries, the selection of the impact assessment methodology and the procedure followed for interpreting the results. The need for stricter adherence to ISO methodological standards to ensure quality and transparency is made clear and emerging challenges for LCA applications in WWT are discussed, including: a paradigm shift from pollutant removal to resource recovery, the adaptation of LCA methodologies to new target compounds, the development of regional factors, the improvement of the data quality and the reduction of uncertainty. Finally, the need for better integration and communication with decision-makers is highlighted. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The aim of the study was to compare subjective and quantitative voice characteristics changes after endolaryngeal microsurgery with respect to different postoperative follow-up term. We evaluated 80 surgically-treated patients aged 14-81 years (mean 42.6+/-13.8 years) with benign vocal cord (VC) lesions (polyps, n=37; cysts, n=16; Reinke's edema, n=18; papilomata, n=9). Patients were evaluated three times - before operation, less than two weeks (mean 1.0+/-0.4) following the operation and more than two weeks (mean 6.5+/-3.9) following the operation. Control group consisted of 122 healthy voice patients. Subjective voice evaluation composed of experts assessment (GRBAS hoarseness scale, visual analogue scale (VAS) of voice quality) and patients self-evaluation (VAS, voice handicap index, and the impression of what repercussions the voice problem has on professional life and emotions). Seven quantitative voice parameters obtained from voice range profile, laryngostroboscopy and registering of maximum phonation time were analyzed as well as overall vocal dysfunction degree (VDD). The data of second postoperative examination were statistically significantly better compared to the first postoperative follow-up (pvoice (G=0) was found for 13.8% (11), quantitatively (VDD=0) for 22.5% (18) of patients, during the second - 63.8% (51) and 53.8% (43). The best results were for patients with vocal cords polyps. The complex voice assessment may be useful for evaluation of voice function recovery and efficacy of surgical treatment.

    The impairment of formation and maintenance of a formed fibrin clot contributes to the prolonged bleeding and high incidence of rebleeding in upper gastrointestinal haemorrhage. To investigate the basis for the use of drug therapy in gastric bleeding, this study used thrombelastography to determine the effects of pharmacological manipulation of gastric juice on coagulation and fibrinolysis. The thrombelastograph is a mechanical device that provides a visual assessment of all stages of coagulation and fibrinolysis. The effects of fresh and pharmacologically changed gastric juice was assessed after its addition to fresh whole blood in the thrombelastograph cuvette. Pharmacological manipulation was achieved through alkalisation or through addition of tranexamic acid, aprotinin, or sucralfate. Fresh gastric juice delayed clot formation, decreased maximum clot amplitude, and stimulated clot lysis. Alkalisation inhibited the lytic effects of fresh gastric juice and improved the induced abnormalities in coagulation. Tranexamic acid partially inhibited gastric juice induced clot lysis but did not exhibit a beneficial effect on coagulation. Sucralfate, and to a lesser extent aprotinin significantly inhibited fibrinolysis but exacerbated the detrimental effect of gastric juice on the parameters of coagulation. Alkalisation of gastric juice reduces the adverse effect on coagulation and fibrinolysis. Tranexamic acid, aprotinin, and sucralfate can all reduce or inhibit clot lysis, but the adverse effects on clot formation may outweigh any potential benefit in the treatment of gastrointestinal bleeding.

    Urban stormwater contains a complex mixture of contaminants that can be acutely toxic to aquatic biota. Green stormwater infrastructure (GSI) is a set of evolving technologies intended to reduce impacts on natural systems by slowing and filtering runoff. The extent to which GSI methods work as intended is usually assessed in terms of water quantity (hydrology) and quality (chemistry). Biological indicators of GSI effectiveness have received less attention, despite an overarching goal of protecting the health of aquatic species. Here we use the zebrafish (Danio rerio) experimental model to evaluate bioinfiltration as a relatively inexpensive technology for treating runoff from an urban highway with dense motor vehicle traffic. Zebrafish embryos exposed to untreated runoff (48-96h; six storm events) displayed an array of developmental abnormalities, including delayed hatching, reduced growth, pericardial edema, microphthalmia (small eyes), and reduced swim bladder inflation. Three of the six storms were acutely lethal, and sublethal toxicity was evident across all storms, even when stormwater was diluted by as much as 95% in clean water. As anticipated from exposure to cardiotoxic polycyclic aromatic hydrocarbons (PAHs), untreated runoff also caused heart failure, as indicated by circulatory stasis, pericardial edema, and looping defects. Bioretention treatment dramatically improved stormwater quality and reversed nearly all forms of developmental toxicity. The zebrafish model therefore provides a versatile experimental platform for rapidly assessing GSI effectiveness.

    The multi-criteria analysis gives the opportunity to researchers, designers and decision-makers to examine decision options in a multi-dimensional fashion. On this basis, four tertiary wastewater treatment (WWT) technologies were assessed regarding their sustainability performance in producing recycled wastewater, considering a 'triple bottom line' approach (i.e. economic, environmental, and social). These are powdered activated carbon adsorption coupled with ultrafiltration membrane separation (PAC-UF), reverse osmosis, ozone/ultraviolet-light oxidation and heterogeneous photo-catalysis coupled with low-pressure membrane separation (photocatalytic membrane reactor, PMR). The participatory method called simple multi-attribute rating technique exploiting ranks was employed for assigning weights to selected sustainability indicators. This sustainability assessment approach resulted in the development of a composite index as a final metric, for each WWT technology evaluated. The PAC-UF technology appears to be the most appropriate technology, attaining the highest composite value regarding the sustainability performance. A scenario analysis confirmed the results of the original scenario in five out of seven cases. In parallel, the PMR was highlighted as the technology with the least variability in its performance. Nevertheless, additional actions and approaches are proposed to strengthen the objectivity of the final results.

    Full Text Available Iron deficiency anaemia (IDA is the main extraintestinal manifestation affecting patients with inflammatory bowel disease (IBD. The Health Technology Assessment approach was applied to evaluate the sustainability of intravenous (IV iron formulations in the Italian hospital setting, with particular focus on ferric carboxymaltose. Data on the epidemiology of IBD and associated IDA, in addition to the efficacy and safety of IV iron formulations currently used in Italy, were retrieved from scientific literature. A hospital-based cost-analysis of the outpatient delivery of IV iron treatments was performed. Organizational and ethical implications were discussed. IDA prevalence in IBD patients varies markedly from 9 to 73%. IV iron preparations were proven to have good efficacy and safety profiles, and ferric carboxymaltose provided a fast correction of haemoglobin and serum ferritin levels in iron-deficient patients. Despite a higher price, ferric carboxymaltose would confer a beneficial effect to the hospital, in terms of reduced cost related to individual patient management and additionally to the patient by reducing the number of infusions and admissions to healthcare facilities. Ethically, the evaluation is appropriate due to its efficacy and compliance. This assessment supports the introduction of ferric carboxymaltose in the Italian outpatient setting.

    Full Text Available Background Bone grafting is a common surgical technique to augment bone regeneration in orthopedic surgery. Autologous bone graft harvesting is the reliable treatment option and iliac crest is the most common harvesting site for healing bone fractures. However, the results of iliac crest bone graft harvesting are associated with morbidity and a number of complications. Objectives The aim of this study was to assess donor site complications of scaphoid nonunion, to find clinical outcomes and the impact of iliac crest bone graft on age, gender, pain, numbness, itching, nerve injury and scar appearance of patients. Methods In a prospective review of 61 cases of iliac crest bone graft procedures at the Shafa hospital from 2013 to 2014, complications including pain, infection, hematoma, stress fracture, hypertrophic scars, numbness area and itching were assessed clinically. Results Pain identified as the most common complication. The most common complications following postoperative pain at the donor site that reduced after six weeks were: numbness 3.27%, unsatisfactory scar appearance 3.27% and itching discomfort 1.63%. Conclusions Harvesting of iliac crest bone graft can be the ideal way to prepare graft procedures required surgery scaphoid nonunion fractures with minimal complications. Nevertheless, with an adequate preoperative planning and appropriate surgical technique, the prevalence of these complications can be reduced.

    In the continuation of PYROREP (FP5), the pyrochemical domain of EUROPART (FP6) involves today 7 European participants and 2 international partners in order to assess treatment processes which could be used in a broad variety of fuel cycles: molten salt reactor spent fuel, metallic, oxide, carbide or nitride fuels from any reactors. Indeed, a pyrochemical process is not sensitive to radiolysis, and obviously to temperature effects, and could afford to treat fuels after a short cooling period, even at high concentrations. Within EUROPART, the chemistry of actinides and of some fission products was studied in depth in either chloride or fluoride molten salts. Laboratory-scale demonstration experiments were used in order to assess electrolytic processes in molten chlorides and liquid-liquid reductive extraction in molten fluoride/liquid aluminum. An electrolysis process is also under development in molten fluoride. To complete the studies, the development of devices and the modeling of processes are taken into consideration. In order to be fitted for acceptance, a process has to produce minimal quantities of wastes, compatible with storage constraints. Therefore, decontamination techniques, as well as materials suitable for disposal, have to be developed. Fission products precipitation by carbonate and phosphate, and filtration on zeolites were studied. Some original confinement matrices such as sodalite or pollucite were also studied. Integration studies have been carried out in order to evaluate and to compare some selected process flowsheets and possibly to redirect development programs. (authors)

  2. Human Laboratory Settings for Assessing Drug Craving; Implications for the Evaluation of Treatment Efficacy

    2011-04-01

    Full Text Available Research on assessing craving in laboratory settings often involves inducing and then measuring craving in subjects. Cue-induced craving is studied in laboratory settings using the cue reactivity paradigm, in which drug-related photos, videos, evocative scripts, olfactory cues, and paraphernalia may induce craving. Cue-induced craving evoked by drug-related stimuli could be associated with relapse and recurrence of drug addiction. In this article, the authors review different methods of assessing craving in laboratory settings and explain how human laboratory settings can bridge the gap between randomized clinical trials (RCTs and animal models on pharmacological treatments for drug dependence. The brief reviewed literature provides strong evidence that laboratory-based studies of craving may improve our understanding of how subjective reports of drug craving are related to objective measures of drug abuse and laboratory settings provide an opportunity to measure the degree to which they co-vary during pharmacological interventions. This issue has important implications inclinical studies.

    Full Text Available Background/Aim. Alveolar osteitis (AO is the extraction wound healing disorder with a presence of severe pain. Low level laser therapy stimulates cell metabolism and microcirculation, have has pronounced analgesic, antiedematous and anti-inflammatory effect and speeds up wound healing process. The aim of this study was to present results of clinical research that examined the effectiveness of low level laser in pain relief and healing of extraction wounds with alveolar osteitis in the lower jaw which was formed on the second day after tooth extraction. Methods. The study was conducted on 60 subjects divided into the study and the control group. In both groups extraction wounds were processed in similar way, except that in the study group was applied daily treatment of low level laser with a total of eight sessions of radiation, while in the control group extraction wounds were dressed with zinc oxide eugenol paste, which was changed every 48 hours up to the pain cessation. Measurement of pain intensity was done with a visual analogue scale (VAS 10 min prior to processing of extraction wounds and daily for the next eight days. Assessment of the effectiveness of low level laser on healing of extraction wounds was performed on the day eight of the treatment. Results. On the day five after beginning of the treatment of extraction wounds with alveolar osteitis in the patients of the study group a lower average value of pain as compared to the control group was registered. This difference was increased within the following days. Extraction wounds healing in the study group was more successful and faster than in the control group. Conclusion. This study suggested that the reduction of pain was more pronounced in the patients with alveolar osteitis whose extraction wounds were subjected to low level laser radiation in comparison to those in which extraction wounds were treated with zinc oxide eugenol paste.

    This study is aimed at optimizing a low energy sonication (LES) treatment for granular activated carbon (GAC)-colonizing biomass detachment and determination, evaluating detachment efficiency and the effects of ultrasound exposure on bacterial cell viability. GAC samples were collected from two filters fed with groundwater. Conventional heterotrophic plate count (HPC) and fluorescence microscopy with a double staining method were used to evaluate cell viability, comparing two LES procedures, without and with periodical bulk substitution. A 20 min LES treatment, with bulk substitution after cycles of 5 min as maximum treatment time, allowed to recover 87%/100% of attached biomass, protecting detached bacteria from ultrasound damaging effects. Observed viable cell inactivation rate was 6.5/7.9% cell/min, with membrane-compromised cell damage appearing to be even higher (11.5%/13.1% cell/min). Assessing bacterial detachment and damaging ultrasound effects, fluorescence microscopy turned out to be more sensitive compared to conventional HPC. The optimized method revealed a GAC-colonizing biomass of 9.9 x 10(7) cell/gGAC for plant 1 and 8.8 x 10(7) cell/gGAC for plant 2, 2 log lower than reported in literature. The difference between the two GAC-colonizing biomasses is higher in terms of viable cells (46.3% of total cells in plant 1 GAC-colonizing biomass compared to the 33.3% in plant 2). Studying influent water contamination through multivariate statistical analyses, apossible combined toxic and genotoxic effect of chromium VI and trichloroethylene was suggested as a reason for the lower viable cell fraction observed in plant 2 GAC-colonizing population.

  5. Agomelatine in the treatment of major depressive disorder: an assessment of benefits and risks.

    2014-09-01

    Agomelatine (AGM) was approved for the treatment of major depressive disorder (MDD) in adults by the European Medicines Agency (EMA) in February 2009. It is an analogue of melatonin and features a unique pharmacodynamic profile with agonism on both types of melatonergic receptors (MT1/MT2) and antagonism at serotonergic 5-HT2C receptors. There is, however, an ongoing debate regarding the efficacy and safety of this novel antidepressant agent, originally evoked by claims of a significant publication bias underlying the assessment of AGM being an effective antidepressant. Indeed, two recent comprehensive metaanalyses of published and unpublished clinical trials found evidence for a relevant publication bias. However, due to its statistically significant advantage over placebo based on the results of these metaanalyses AGM must be referred to as an effective antidepressant agent in the acute phase of MDD. However, the effect sizes of AGM in the treatment of MDD were evaluated as being small in comparison to other antidepressant agents. In addition, there is insufficient evidence for the efficacy of AGM in relapse prevention of MDD. Apart from efficacy issues, AGM appears to have the potential to exhibit severe hepatotoxicity (the EMA has identified AGM-associated "hepatotoxic reactions" as a new safety concern in September 2013) that is currently poorly understood. Considering these aspects, it seems inappropriate to evaluate AGM as an antidepressant agent of first choice. Nevertheless, its unique mechanism of action with particular sleep modulating effects may represent a specific treatment strategy for patients with particular characteristics; further studies with thorough characterization of patients are needed to test this hypothesis.

    Gastric cancer is responsible for 10 % of all cancer-related deaths worldwide. With improved operative techniques and neo-adjuvant therapy, survival rates are increasing. Outcomes of interest are shifting to quality of life (QOL), with many different tools available. The aim of this study was to assess which patient-reported outcome measures (PROMs) are used to measure QOL after a gastrectomy for cancer. A comprehensive search was conducted for original articles investigating QOL after gastrectomy. Two authors independently selected relevant articles, conducted clinical appraisal and extracted data (P.J. and J.S.). Out of 3414 articles, 26 studies were included, including a total of 4690 patients. These studies included ten different PROMs, which could be divided into generic, symptom-specific and disease-specific questionnaires. The EORTC and the FACT questionnaires use an oncological overall QOL module and an organ-specific module. Only one validation study regarding the use of the EORTC after surgery for gastric cancer was available, demonstrating good psychometric properties and clinical validity. A great variety of PROMs are being used in the measurement of QOL after surgery for gastric cancer. A questionnaire with a general module along with a disease-specific module for the assessment of QOL seems most desirable, such as the EORTC and the FACT with their specific modules. Both are developed in different treatment modalities, such as in surgical patients. EORTC is the most widely used questionnaire and therefore allows for comparison of new studies to existing data. Future studies are needed to assess content validity in surgical gastric cancer patients.

Malignant gliomas have high morbidity and mortality. Even with optimal treatment, median survival is only 12–15 months for glioblastomas and 2–5 years for anaplastic gliomas. However, recent advances in imaging and quantitative analysis of image data have led to earlier diagnosis of tumors and tumor response to therapy, providing oncologists with a greater time window for therapy management. In addition, improved understanding of tumor biology, genetics, and resistance mechanisms has enhanced surgical techniques, chemotherapy methods, and radiotherapy administration. After proper diagnosis and institution of appropriate therapy, there is now a vital need for quantitative methods that can sensitively detect malignant glioma response to therapy at early follow-up times, when changes in management of nonresponders can have its greatest effect. Currently, response is largely evaluated by measuring magnetic resonance contrast and size change, but this approach does not take into account the key biologic steps that precede tumor size reduction. Molecular imaging is ideally suited to measuring early response by quantifying cellular metabolism, proliferation, and apoptosis, activities altered early in treatment. We expect that successful integration of quantitative imaging biomarker assessment into the early phase of clinical trials could provide a novel approach for testing new therapies

    Full Text Available Aims. The aim of this study was to assess the self-perception of dental appearance among Eastern Nepalese patients using aesthetic component (AC of the index of orthodontic treatment need (IOTN and to compare it with that of an orthodontist’s assessment using the same scale and determine whether gender, area of residence, and level of education influence subject’s self-perception and orthodontist’s ratings. Methods. A total of 252 subjects (equal number of male and female were conveniently selected. The average ages of subjects were 22.33±2.114 years. The level of subject’s perception and orthodontist’s assessment was analyzed by nonparametric Chi square test. Kappa coefficient was done to verify its agreement. The Spearman’s correlation test was used to check the association of educational level and age. Mann-Whitney test was used to check the associations of sex and areas of residence. Results. The demand for treatment was significantly associated with the perception of the subject and orthodontist’s assessment. However, age, gender, and educational level were statistically insignificant in influencing subject perception and orthodontist’s assessment. Conclusion. Patient’s self-perception should be given equal importance while planning orthodontic treatment.

    The high living standard of many industrial countries has directly lead to an increase in the amount of municipal solid waste generated. Parallel to this increase in waste, there has been a raising demand for environmentally benign waste treatment processes. In Switzerland, the predominant way of treatment is incineration. Since the environmental impact of waste incineration depends on the technology used, a comprehensive assessment of the different thermal processes is necessary. In order to determine the environmental impact, we propose a model that quantifies the emissions and resource use resulting from the incineration of waste using different technologies, the landfills for the incineration residues, the transport of waste, related infrastructure, as well as the production of ancillary products. Using the Life-Cycle Assessment (LCA) methodology, we performed a case study that compared the conventional grate technology to new high temperature processes recovering metals and vitrifying the incineration residues. The results show that if the plant is equipped with a modern gas purification system the incineration process itself is not a key environmental problem of the system considered. Using the energy gained from waste incineration as the functional unit, the environmental impacts of incineration plants are comparable to that of a conventional power plant. If long-term time horizons are considered, the critical aspect is the release of heavy metals from the landfilled incineration residues. Due to the better quality of the solid outputs new technologies have a lower potential for environmental impact than the conventional grate technology. This, however, depends on the time horizon considered. With a temporal system boundary of 100 years, the grate technology appears better, because new technologies generally use more energy and short-term emissions are of minor importance no matter what technology is used.

    Shared decision-making between patients and healthcare professionals is crucial to guarantee adequate coherence between patient values and preferences, caring aims and treatment intensity, which is key for the provision of patient-centred healthcare. The assessment of such interventions are essential for caring continuity purposes. To do this, reliable and easy-to-use assessment systems are required. This study describes the results of the implementation of a hospital treatment intensity assessment tool. The pre-implementation and post-implementation results were compared between two cohorts of patients assessed for one month. Some record of care was registered in 6.1% of patients in the pre-implementation group (n=673) compared to 31.6% of patients in the post-implementation group (n=832) (P<.01), with differences between services. Hospital mortality in both cohorts is 1.9%; in the pre-implementation group, 93.75% of deceased patients had treatment intensity assessment. In hospital settings, the availability of a specific tool seems to encourage very significantly shared decision-making processes between patients and healthcare professionals -multiplying by more than 5 times the treatment intensity assessment. Moreover, such tools help in the caring continuity processes between different teams and the personalisation of caring interventions to be monitored. More research is needed to continue improving shared decision-making for hospital patients. Copyright © 2015 SEGG. Published by Elsevier Espana. All rights reserved.

To study change of knee joints functional disability in pts with predominantly I-II stage of knee osteoarthritis (OA with clinical tests and WOMAC index for assessment of efficacy of treatment with Chondrolon and Zel T in polyclinic. Material and methods. 70 pts with I and II stage of OA according to Kellgren-Lawrence aged from 40 to 67 years were included. They were divided in 2 groups (30 pts in group I and40 pts in group II. Group I pts were treated with Chondrolon and group II pts – with Zel T. Treatment efficacy was assessed with WOMAC index, functional Lequesne index, pain on VAS at rest and at movement, knee mobility, time of walking for 30 m and walking stairs. Results. Positive changes of all parameters were revealed in both groups: significant improvement of pain on VAS, functional tests, Lequesne index, WOMAC scales was achieved. During treatment with Zel T improvement of the efficacy measures increased slower, mainly after 12 weeks of treatment (during treatment with Chondrolon – after8 weeks. Both drugs provided functional improvement assessed by WOMAC index butChondrolon was more effective. Conclusion. Chondrolon and Zel T can be used for treatment of OA at I or II stage with moderate knee joints functional disability. Course of treatment with Zel T should be continued not less than 3 months and with Chondrolon – 2 months.

    Nowadays, the environmental performances of wastewater treatment systems are not properly analyzed. Thus, the development of an exhaustive and reliable method is needed to help stakeholders to choose the best environmental solutions. Life cycle assessment (LCA) was selected as a starting point to answer this problem. LCA has been tested. This tool is essential to analyze the environmental performances of wastewater treatment systems. In order to fulfill our goal, the best compromise seems to be the association of LCA, to assess global impacts, with others methodologies, to assess local impacts. Finally, a software has been developed to compare urban sludge treatment and recovering process trains. Two impacts, energy and greenhouse effect, are currently included in. The software and its development steps are described and illustrated through two case studies. This tool has made LCA easier to apply and more useful to wastewater field stakeholders. (author)

    Full Text Available BACKGROUND : Organophophorous poisoning constitutes one of the most frequent poisoning in clinical practice all over the country and especially in this area where agriculture is the chief economic occupation. Acute organophophorous poisoning ranks foremost in the list of agents which causes acute pesticide poisoning in the developing countries. Acute poisoning, accidental or due to deliberate ingestion or inhalation of these organophosphate chemicals is an important and one of the most common medical emergencies. Hence the present stud y is undertaken to assess severity of poisoning, management and outcome of organophosphorous poisoning cases admitted in Government General Hospital, Kakinada, A. P. AIMS/OBJECTIVES: 1. Assessment of severity of Organophosphorous poisoning according to Dri esbach’s criteria 2. To study the morbidity and mortality in these patients.

    Full Text Available BACKGROUND: As a population, non-medical prescription opioid users are not well-defined. We aimed to derive and describe typologies of prescription opioid use and nonmedical use using latent class analysis in an adult population being assessed for substance abuse treatment. METHODS: Latent class analysis was applied to data from 26,314 unique respondents, aged 18-70, self-reporting past month use of a prescription opioid out of a total of 138,928 cases (18.9% collected by the Addiction Severity Index-Multimedia Version (ASI-MV®, a national database for near real-time prescription opioid abuse surveillance. Data were obtained from November 2005 through December 2009. Substance abuse treatment, criminal justice, and public assistance programs in the United States submitted data to the ASI-MV database (n = 538. Six indicators of the latent classes derived from responses to the ASI-MV, a version of the ASI modified to collect prescription opioid abuse and chronic pain experience. The latent class analysis included respondent home ZIP code random effects to account for nesting of respondents within ZIP code. RESULTS: A four-class adjusted latent class model fit best and defined clinically interpretable and relevant subgroups: Use as prescribed, Prescribed misusers, Medically healthy abusers, and Illicit users. Classes varied on key variables, including race/ethnicity, gender, concurrent substance abuse, duration of prescription opioid abuse, mental health problems, and ASI composite scores. Three of the four classes (81% of respondents exhibited high potential risk for fatal opioid overdose; 18.4% exhibited risk factors for blood-borne infections. CONCLUSIONS: Multiple and distinct profiles of prescription opioid use were detected, suggesting a range of use typologies at differing risk for adverse events. Results may help clinicians and policy makers better focus overdose and blood-borne infection prevention efforts and intervention strategies

    The study assessed the air quality of four wastewater treatment plants (WWTPs) by monitoring levels of hydrogen sulfide (H2S) and endotoxin. Samples were taken over a 1-year period (2001-2002). The unit operations at each WWTP were categorized as: (a) grit removal, (b) primary clarification, (c) biological treatment, (d) secondary clarification, (e) sludge dewatering, and (f) digestion. Temperature and humidity were monitored simultaneously, whereas airborne H2S and endotoxin were monitored at each of the six unit operations in each plant. Carbonaceous biochemical oxygen demand (CBOD) and total incoming flow of the day of visit were also recorded. The geometric means of H2S concentration were less than 1 ppm and endotoxin ranged from 6-1247 EU/m3. A mixed model analysis of covariance (ANCOVA) was used for the statistical analysis. While temperature was not associated with the levels of both contaminants, humidity was influential on the level of H2S (p < 0.01) but not of endotoxin. CBOD did not affect the levels of either contaminant; however, incoming flows showed an association with the levels of H2S (p < 0.05). The concentrations of H2S in the six unit operations were statistically different, whereas endotoxin did not show any differences in concentrations between units. Individual comparisons proved that concentrations of H2S in the grit removal and sludge dewatering unit operations were statistically higher than the other operations. Overall, the concentrations of H2S varied depending on total incoming flow, humidity, and different unit operations. This trend was not observed for endotoxin. The results showed that the factors analyzed affected concentrations of H2S and endotoxin differently. Therefore, different control methods for endotoxin and H2S need to be considered to effectively reduce their concentrations at WWTPs.

    In the present work, an extensive study on the presence of eighteen pharmaceuticals and personal care products (PPCPs) in eight wastewater treatment plants (WWTPs) of Greece has been conducted. The study covered four sampling periods over 1-year, where samples (influents; effluents) from eight WWTPs of various cities in Greece were taken. All WWTPs investigated are equipped with conventional activated sludge treatment. A common pre-concentration step based on SPE was applied, followed by LC-UV/Vis-ESI-MS. Further confirmation of positive findings was accomplished by using LC coupled to a high resolution Orbitrap mass spectrometer. The results showed the occurrence of all target compounds in the wastewater samples with concentrations up to 96.65 μg/L. Paracetamol, caffeine, trimethoprim, sulfamethoxazole, carbamazepine, diclofenac and salicylic acid were the dominant compounds, while tolfenamic acid, fenofibrate and simvastatin were the less frequently detected compounds with concentrations in effluents below the LOQ. The removal efficiencies showed that many WWTPs were unable to effectively remove most of the PPCPs investigated. Finally, the study provides an assessment of the environmental risk posed by their presence in wastewaters by means of the risk quotient (RQ). RQs were more than unity for various compounds in the effluents expressing possible threat for the aquatic environment. Triclosan was found to be the most critical compound in terms of contribution and environmental risk, concluding that it should be seriously considered as a candidate for regulatory monitoring and prioritization on a European scale on the basis of realistic PNECs. The results of the extensive monitoring study contributed to a better insight on PPCPs in Greece and their presence in influent and effluent wastewaters. Furthermore, the unequivocal identification of two transformation products of trimethoprim in real wastewaters by using the advantages of the LTQ Orbitrap capabilities

    The seventeen Sustainable Development Goals (SDG) represent a challenge for citizens and countries around the world by working together to reduce social inequality, to fight poverty and climate change. The Goal six water and sanitation aims for ensuring, among others, the protection and restoration of water-related ecosystem (target 6.6) and encouraging the water use efficiency (target 6.3). The commitment to this goal is not only the development of sanitation infrastructure, but also incorporates the necessity of a sustainable and efficient management from ecological and economic perspectives. Following this approach, we propose a framework for assessing the waste water treatment plant (WWTP) management based on the Water Footprint (WF) principles. The WF as indicator is able to highlight the beneficial role of WWTPs within the environment and provide a complementary information to evaluate the impact of a WWTP regarding to the use of freshwater and energy. Therefore, the footprint family provides an opportunity to relate the reduction of pollutant load in a WWTP and the associated consumptions in terms of electricity and chemical products. As a consequence, the new methodology allows a better understanding of the interactions among water and energy resources, economic requirements and environmental risks. Because of this, the current technologies can be improved and innovative solutions for monitoring and management of urban water use can be integrated. The WF was calculated in four different WWTP located in the North East of Extremadura (SW Spain) which have activated sludge process as secondary treatment. This zone is characterized by low population density but an incipient tourism development. The WF estimation and its relationship with the electricity consumption examines the efficiency of each WWTP and identifies the weak points in the management in terms of the sustainability. Consequently, the WF establishes a benchmark for multidisciplinary decision

    Full Text Available Abstract Background A number of recently published randomized controlled trials conducted in developed countries have reported no advantage for assertive interventions over standard care models. One possible explanation could be that so-called "standard care" has become more comprehensive in recent years, incorporating some of the salient aspects of assertive models in its modus operandi. Our study represents the first randomised controlled trial assessing the effect of a modified assertive treatment service on readmission rates and other measures of outcome in a developing country. Methods High frequency service users were randomized into an intervention (n = 34 and a control (n = 26 group. The control group received standard community care and the active group an assertive intervention based on a modified version of the international model of assertive community treatment. Study visits were conducted at baseline and 12 months with demographic and illness information collected at visit 1 and readmission rates documented at study end. Symptomatology and functioning were measured at both visits using the PANSS, CDSS, ESRS, WHO-QOL and SOFAS. Results At 12 month follow-up subjects receiving the assertive intervention had significantly lower total PANSS (p = 0.02 as well as positive (p Conclusions Our results indicate that assertive interventions in a developing setting where standard community mental services are often under resourced can produce significant outcomes. Furthermore, these interventions need not be as expensive and comprehensive as international, first-world models in order to reduce inpatient days, improve psychopathology and overall levels of functioning in patients with severe mental illness.

    Full Text Available In recent years, there have been a number of advances in the pathogenesis and treatment of atherosclerosis and in assessing prognosis in carotid atherosclerosis. Risk stratification to improve vascular prevention by identifying patients most likely to benefit from intensive therapy is much improved by measuring carotid plaque burden. In patients with asymptomatic carotid stenosis, a number of modalities can be used to identify the 10-15% who could benefit from endarterectomy or stenting. Transcranial Doppler embolus detection, echolucency and ulceration on 3D ultrasound, intraplaque hemorrhage on magnetic resonance imaging (MRI, and reduced cerebrovascular reserve are useful already; new approaches including plaque texture on ultrasound and imaging of plaque inflammation and early calcification on positron emission tomography/computed tomography (PET/CT are in development. The discovery that the intestinal microbiome produces vasculotoxic metabolites from dietary constituents such as carnitine in meat (particularly red meat and phosphatidylcholine from egg yolk and other sources has revolutionized nutritional aspects of vascular prevention. Because many of these vasculotoxic metabolites are removed by the kidney, it is particularly important in patients with renal failure to limit their intake of red meat and egg yolk. A new approach to lowering low-density lipoprotein (LDL cholesterol by blocking the action of an enzyme that destroys LDL receptors promises to revolutionize vascular prevention once less costly treatments are developed, and a new approach to vascular prevention—“treating arteries instead of risk factors”—shows promise but requires randomized trials. These advances all promise to help in the quest to prevent strokes in high-risk patients.

    Conventional industrial processes are emission sources of unintended nanoparticles which are potentially harmful for the environment and human health. The aim of this study is to assess airborne nanoparticle release from aluminum surface treatment processes in various workplaces. Two direct reading instruments, a scanning mobility particle sizer to measure size distribution and a nanoparticle surface area monitoring to measure the surface area of particles deposited in the human lung, were employed to perform area monitoring. The lacquering paint was the process which released the highest concentration of particles from 10-487 nm (7.06 × 10(6) particles/cm(3)). The lacquering baths process emitted particles of the largest average size (76.9 nm) and the largest surface area deposited in the human lung (167.4 µm(2)/cm(3)). Conversely, the anodizing bath process generated particles of the smallest average size (44.3 nm) and the lowest human lung-deposited surface area (1.2 µm(2)/cm(3)). The total number of particles and the surface area can only be fairly correlated for environments in which the surface area presented higher values. The transmission electron microscopy analysis confirmed the presence of aluminum oxide particles of different dimensions near the LB and AB areas and polymeric-based particles near the LP areas. The findings of this study indicated that lacquering and anodizing surface treatments are indeed responsible for the emission of airborne nanoparticles. It also highlights the importance of control strategies as a means of protecting workers' health and environment.

    Background and objectives: Cinacalcet, a novel calcimimetic, targets the calcium-sensing receptor to lower parathyroid hormone (PTH), calcium, and phosphorus levels in dialysis patients with secondary hyperparathyroidism (SHPT). This study compared the efficacy of a cinacalcet-based regimen with unrestricted conventional care (vitamin D and phosphate binders) for achieving the stringent National Kidney Foundation Kidney Disease Outcomes Quality Initiative (KDOQI) targets for dialysis patients. Study design: In this multicenter, open-label study, hemodialysis patients with poorly controlled SHPT were randomized to receive conventional care (n = 184) or a cinacalcet-based regimen (n = 368). Doses of cinacalcet, vitamin D sterols, and phosphate binders were adjusted during a 16-wk dose-optimization phase with the use of algorithms that allowed cinacalcet to be used with adjusted doses of vitamin D. The primary end point was the proportion of patients with mean intact PTH ≤300 pg/ml during a 7-wk efficacy assessment phase. Results: A higher proportion of patients receiving the cinacalcet-based regimen versus conventional care achieved the targets for PTH (71% versus 22%, respectively; P < 0.001), Ca × P (77% versus 58%, respectively; P < 0.001), calcium (76% versus 33%, respectively; P < 0.001), phosphorus (63% versus 50%, respectively; P = 0.002), and PTH and Ca × P (59% versus 16%, respectively, P < 0.001), and allowed a 22% reduction in vitamin D dosage in patients receiving vitamin D at baseline. Achievement of targets was greatest in patients with less severe disease (intact PTH range, 300 to 500 pg/ml) and the cinacalcet dose required was lower in these patients (median = 30 mg/d). Conclusions: Compared with conventional therapy, a cinacalcet-based treatment algorithm increased achievement of KDOQI treatment targets in dialysis patients in whom conventional therapy was no longer effective in controlling this disease.

    Aim: To put forward criteria for the pressure assessment in the operation of intercavemous embedding of bulboperineal urethra for the treatment of urinary incontinence after prostatic operation. Methods: A Fl4 urethral catheter is inserted during the operation and upon suturing the corpora cavemosa centrally, the catheter is slowly pushed in and pulled out in order that the operator feels a certain degree of close-fit resistance. The degree of tightness of the stitches,which regulate the compression pressure, is adjusted in accordance with this close-fit sensation. To further ascertain the adequacy of the force of compression, the bladder is filled with 300 ml physiological saline and observe the appropriateness (size and continuity) of the outflow stream when the lower abdomen is depressed with a pressure of 80-90 cm H2O. The operation was given to six patients suffered from urinary incontinence for 20 or more months after prostatic operation. Results: Five cases achieved complete recovery, while the therapeutic effect of the 6th one was not satisfactory. A second stage operation was carried out 3 months later with the addition of one more stitch both proximally and distally to reinforce the compression force. The condition was improved dramatically. The follow-up period averaged 3.5 years. Conclusion: The adequacy of the compression pressure exerted by the juxtaposed corpora cavernosa is the key point determining the outcome of the operation. The measures for assessing the compression pressure suggested by the authors are helpful in obtaining the good results of the present paper (6/6 success) as compared with 25/34success in the previous report.

    An efficient chiral method-based using liquid chromatography-high resolution-mass spectrometry analytical method has been validated for the determination of climbazole (CBZ) enantiomers in wastewater and sludge with quantification limits below the 1 ng/L and 2 ng/g range, respectively. On the basis of this newly developed analytical method, the stereochemistry of CBZ was investigated over time in sludge biotic and sterile batch experiments under anoxic dark and light conditions and during wastewater biological treatment by subsurface flow constructed wetlands. CBZ stereoselective degradation was exclusively observed under biotic conditions, confirming the specificity of enantiomeric fraction variations to biodegradation processes. Abiotic CBZ enantiomerization was insignificant at circumneutral pH and CBZ was always biotransformed into CBZ-alcohol due to the specific and enantioselective reduction of the ketone function of CBZ into a secondary alcohol function. This transformation was almost quantitative and biodegradation gave good first order kinetic fit for both enantiomers. The possibility to apply the Rayleigh equation to enantioselective CBZ biodegradation processes was investigated. The results of enantiomeric enrichment allowed for a quantitative assessment of in situ biodegradation processes due to a good fit (R(2) > 0.96) of the anoxic/anaerobic CBZ biodegradation to the Rayleigh dependency in all the biotic microcosms and was also applied in subsurface flow constructed wetlands. This work extended the concept of applying the Rayleigh equation towards quantitative biodegradation assessment of organic contaminants to enantioselective processes operating under anoxic/anaerobic conditions.

    Full Text Available Abstract Background Patients experience an increasing treatment burden related to everything they do to take care of their health: visits to the doctor, medical tests, treatment management and lifestyle changes. This treatment burden could affect treatment adherence, quality of life and outcomes. We aimed to develop and validate an instrument for measuring treatment burden for patients with multiple chronic conditions. Methods Items were derived from a literature review and qualitative semistructured interviews with patients. The instrument was then validated in a sample of patients with chronic conditions recruited in hospitals and general practitioner clinics in France. Factor analysis was used to examine the questionnaire structure. Construct validity was studied by the relationships between the instrument's global score, the Treatment Satisfaction Questionnaire for Medication (TSQM scores and the complexity of treatment as assessed by patients and physicians. Agreement between patients and physicians was appraised. Reliability was determined by a test-retest method. Results A sample of 502 patients completed the Treatment Burden Questionnaire (TBQ, which consisted of 7 items (2 of which had 4 subitems defined after 22 interviews with patients. The questionnaire showed a unidimensional structure. The Cronbach's α was 0.89. The instrument's global score was negatively correlated with TSQM scores (rs = -0.41 to -0.53 and positively correlated with the complexity of treatment (rs = 0.16 to 0.40. Agreement between patients and physicians (n = 396 was weak (intraclass correlation coefficient 0.38 (95% confidence interval 0.29 to 0.47. Reliability of the retest (n = 211 patients was 0.76 (0.67 to 0.83. Conclusions This study provides the first valid and reliable instrument assessing the treatment burden for patients across any disease or treatment context. This instrument could help in the development of treatment strategies that are both

    The aim of this study was to compare results of and develop guidelines for mandatory allocation of sexually transgressive juveniles to Multisystemic Therapy - Problem Sexual Behavior (MST-PSB), Secure Youth Care (SYC), or Forensic Youth Care (FYC), based on the risk-need-responsivity model. Results of current allocation showed a population with relatively less treatment needs to receive community-based MST-PSB, compared with populations receiving residential SYC and FYC. Furthermore, estimated recidivism risk levels did not always support the need for risk reduction by the imposition of limitation of freedom of movement and maximum supervision, provided by all three treatment modalities. Based on the assessed sexual recidivism risk, 38% of the juveniles in FYC, 7% in SYC, and 24% in MST-PSB received treatment that was too intensive, which is considered detrimental to motivation and development. Future allocation practices could benefit from assessing treatment needs and recidivism risk, by use of an actuarial tool.

    Chronic hepatitis C virus(HCV) is a global concern. With the 2014 Food and Drug Administration approvals of two direct-acting antiviral(DAA) regimens, ledipasvir/sofosbuvir regimen and the ombitasvir/paritaprevir/ritonavir and dasabuvir regimen, we may now be in the era of all-pill regimens for HCV. Until this development, interferon-alpha along with Ribavirin has remained part of the standard of care for HCV patients. That regimen necessitates psychosocial assessment of factors affecting treatment eligibility, including interferon-alpharelated depressive symptoms, confounding psychiatric conditions, and social aspects such as homelessness affecting treatment eligibility. These factors have delayed as much as 70% of otherwise eligible candidates from interferon-based treatment, and have required treating physicians to monitor psychiatric as well as medical side effects throughout treatment. Allpill DAA regimens with the efficaciousness that would preclude reliance upon interferon-alpha or ribavirin have been anticipated for years. Efficacy studies for these recently approved DAA regimens provide evidence to assess the degree that psychosocial assessment and monitoring will be required. With shorter treatment timelines, greatly reduced side effect profiles, and easier regimens, psychosocial contraindications are greatly reduced. However, current or recent psychiatric comorbidity, and drug-drug interactions with psychiatric drugs, will require some level of clinical attention. Evidence from these efficacy studies tentatively demonstrate that the era of needing significant psychosocial assessment and monitoring may be at an end, as long as a manageable handful of clinical issues are managed.

    Full Text Available Aim of this study was to evaluate the ecotoxicity of municipal sewage sludge conditioned with polyelectrolytes, taken from selected sewage treatment plant. Using the bioindication analysis overall toxicity was assessed, which allows to know the total toxicity of all the harmful substances contained in sewage sludge, in many cases acting synergistically. To prepare a sample of sludge for the basic test, all analyses were performed with a ratio of liquid to solid of 10:1 (water extract. Daphnia pulex biological screening test was used. A dilution series of an water extract of sludge were prepared to include within its scope the lowest concentration that causes 100% effect and the highest producing less than 10% of the effect within a specified range of the assay. The results of the test were read after 24 and 48 hours. Based on the research and analysis of test results it proved that the sewage sludge conditioned with polyelectrolytes exhibit the characteristics of eco-toxic.

The approach is widely accepted by experts in emergency medicine and likely improves outcomes by helping health care professionals focusing on the most life-threatening clinical problems. In an acute setting, high-quality ABCDE skills among all treating team members can save valuable time and improve team performance. Dissemination of knowledge and skills related to the ABCDE approach are therefore needed. This paper offers a practical “how-to” description of the ABCDE approach.Keywords: emergency medicine, general medicine, internal medicine, multiple trauma, multiple injury

  14. The Role of MR Enterography in Assessing Crohn’s Disease Activity and Treatment Response

    2016-01-01

    Full Text Available MR enterography (MRE has become the primary imaging modality in the assessment of Crohn’s disease (CD in both children and adults at many institutions in the United States and worldwide, primarily due to its noninvasiveness, superior soft tissue contrast, and lack of ionizing radiation. MRE technique includes distention of the small bowel with oral contrast media with the acquisition of T2-weighted, balanced steady-state free precession, and multiphase T1-weighted fat suppressed gadolinium contrast-enhanced sequences. With the introduction of molecule-targeted biologic agents into the clinical setting for CD and their potential to reverse the inflammatory process, MRE is increasingly utilized to evaluate disease activity and response to therapy as an imaging complement to clinical indices or optical endoscopy. New and emerging MRE techniques, such as diffusion-weighted imaging (DWI, magnetization transfer, ultrasmall superparamagnetic iron oxide- (USPIO- enhanced MRI, and PET-MR, offer the potential for an expanded role of MRI in detecting occult disease activity, evaluating early treatment response/resistance, and differentiating inflammatory from fibrotic strictures. Familiarity with MR enterography is essential for radiologists and gastroenterologists as the technique evolves and is further incorporated into the clinical management of CD.

    Full Text Available The better understanding of the complex mechanism between neural motor control and its resulting joint kinematics and muscle forces allows a better elucidation of the mechanisms behind body growth, aging progression, and disease development. This study aimed at investigating the impact of movement-based structure-modifying treatment strategies on joint kinematics, muscle forces, and muscle synergies of the gait with instrumented implant. A patient-specific musculoskeletal model was used to quantitatively assess the deviations of joint and muscle behaviors between the normal gait and 4 gait modifications (bouncy, medial thrust, midcrouch, and mtp (i.e., gait with forefoot strike. Moreover, muscle synergy analysis was performed using EMG-based nonnegative matrix factorization. Large variation of 19 degrees and 190 N was found for knee flexion/extension and lower limb muscle forces, respectively. EMG-based muscle synergy analysis revealed that the activation levels of the vastus lateralis and tibialis anterior are dominant for the midcrouch gait. In addition, an important contribution of semimembranosus to the medial thrust and midcrouch gaits was also observed. In fact, such useful information could allow a better understanding of the joint function and muscle synergy strategies leading to deeper knowledge of joint and muscle mechanisms related to neural voluntary motor commands.

    Full Text Available Interpersonal communication, psychosocial and mental development of personality and its all other functions take place through the motor control. The most common neurological syndrome is a type of peripheral paresis/paralysis of plexus bracialis, which in most cases occurs at birth and significantly compromises the growth and development of the upper extremities and affects the psychomotor performance. The aim of this study was to evaluate the level of visual perception in children with lesion of plexus brachialis and the effect of the somatopedic treatment over the level of increase of the visual perception. The study sample was consisted of 60 preschool children accommodated at the Rehabilitation Centre “Dr. Miroslav Zotović” in Belgrade (experimental group and examiners that followed regular checkups and had discontinuity in their therapy (control group. For the research purposes, we used The Test for Visual Perception Assessment. By analyzing the results, we concluded that in both, in the first and the second measuring there was a statistically significant correlation between the experimental and the control groups (I measuring: p<0.001, r = 0.408; II measuring: p <0.001, r = 0.593.

    In this study, the occurrence and removal efficiencies of 31 antibiotics, including 11 sulfonamides (SAs), five fluoroquinolones (FQs), four macrolides (MLs), four tetracyclines (TCs), three chloramphenicols (CAPs), and four other antibiotics (Others), were investigated in 12 municipal wastewater treatment plants (WWTPs) in Dalian, China. A total of 29 antibiotics were detected in wastewater samples with the concentration ranging from 63.6 to 5404.6 ng/L. FQs and SAs were the most abundant antibiotic classes in most wastewater samples, accounting for 42.2 and 23.9% of total antibiotic concentrations, respectively, followed by TCs (16.0%) and MLs (14.8%). Sulfamethoxazole, erythromycin, clarithromycin, azithromycin, ofloxacin, and norfloxacin were the most frequently detected antibiotics; of these, the concentration of ofloxacin was the highest in most of influent (average concentration = 609.8 ng/L) and effluent (average concentration = 253.4 ng/L) samples. The removal efficiencies varied among WWTPs in the range of -189.9% (clarithromycin) to 100% (enoxacin, doxycycline, etc), and more than 50% of antibiotics could not be efficiently removed with the removal efficiency less than 65%. An environmental risk assessment was also performed in the WWTP effluents by calculating the risk quotient (RQ), and high RQ values (>1) indicated erythromycin and clarithromycin might cause the ecological risk on organisms in surrounding water near discharge point of WWTPs in this area, which warrants further attention.

    The aim of the present study was to assess patients' acceptance of therapeutic leukocytapheresis known as cytapheresis (CAP) for the treatment of an active flare of inflammatory bowel disease (IBD). A questionnaire was sent to 155 IBD patients who had been treated with CAP for an active flare of IBD at the IBD center of Hyogo College of Medicine between January 2009 and July 2012. In the questionnaire, patients were asked to evaluate CAP including efficacy, safety, unfavorable features and their willingness to be retreated with CAP for a subsequent IBD flare-up. Seventy-eight percent (112 of 155 patients) including 86 with ulcerative colitis and 26 with Crohn's disease completed the questionnaire. The need for coming to hospital for CAP, needle pain during blood access, sparing time for CAP process were scored by 57%, 58%, and 58.9% of the patients, respectively as unfavorable. Patients highly favored the safety of CAP, the sum of very and relatively favorable was 89%, higher than for efficacy (68%). Seventy-two percent of patients favored retreatment with CAP. In binary logistic regression analysis, the levels of satisfaction for efficacy (P disease. Patient's acceptability for CAP appeared to be determined by the balance of these factors.

    An integrated approach combining chemistry and biological methods was conducted to assess the toxicity of seven sewage treatment plant effluents. Solid phase concentration procedures were applied to facilitate the study of organic micro pollutants. A chemical analysis was performed by GC/MS. Organic fraction toxicity was determined by using bioassays such as Daphnia magna and Chlorella vulgaris tests and sub-lethal effects were also evaluated by using Salmonella typhimurium Test (mutagenicity), recombinant yeast screen (estrogenicity), and Oryzias latipes embryo-larval test. More than 49 compounds were detected in the organic fraction due to the various inputs of each effluents. The most frequently detected compounds in the effluents were bisphenol A (BPA), octylphenol (OP), 1,2-benzenedicarboxylic acid, bis(2-ethylhexyl) ester (DEHP) and 1,2-benzenedicarboxylic acid, bis(methylpropyl) ester (DBP). Biological assays showed toxicity effects on D. magna tests in all samples, whereas toxicity on C. vulgaris or S. typhimurium tests were not observed. Estrogenicity and teratogenicity were observed in several samples. The cause-effect relationship could not be established given the high chemical complexity of the effluents and the lack of information available on 70% of the detected compounds subsequent to reviewing various data bases. Nevertheless, due to the high chemical variability revealed by STP effluents, bioassay sets may provide a very useful amount of information for detecting potential toxicity risks.

    Full Text Available Polyvinyl alcohol (PVA sheets based nanofibers were produced by electrospinning technique. Postheat treatment of the produced PVA sheets with temperatures both below and above Tg to improve the mechanical properties of this material is conducted. The morphology, microstructures, and thermal degradation of the nanofibers sheets produced were investigated using scanning electron microscopy (SEM, transmission electron microscope (TEM, and thermal gravimetric analysis (TGA. Produced nanofibers are compact, and entangled with each other, with diameters from around 150 to 210. Some mechanical characteristics of the successfully produced PVA sheets, and heat-treated, are then conducted and assessed employing uniaxial tensile tests at different speeds ranging from 1 mm/min to 100 mm/min. The tensile test results obtained show that the PVA sheets are strain rate sensitive with increasing strength as the speed (i.e., strain rate increases. The yield tensile stress ranges from 2.411 to 6.981 MPa, the ductility (i.e., elongation percent from ∼21 to 60%, and Young modulus ranges from 103 to 0.137 KPa. However, for heat-treated samples, it is found that the yield strength increases almost by ∼35–40% more than the values of untreated cases with values reaching up to about 3.627–9.63 MPa.

    The aim was to develop a liposomal oxymatrine conjugating D-alpha tocopheryl polyethylene glycol 1000 succinate (OMT-LIP) for enhanced therapeutics of hepatic fibrosis. OMT-LIP was prepared using the remote loading method. The influences of formulation compositions on the encapsulation efficiency of OMT-LIP were investigated. Mean particle size, zeta potential, morphology, in vitro release, fibrotic liver targeting, and therapeutics of OMT-LIP were thoroughly assessed. The intraliposomal buffer composition and concentration, extraliposomal phase composition and pH, types of phospholipid, lipid molar ratio composition, and theoretical drug loading are crucial factors to entrap OMT into liposomes. The optimum OMT-LIP presented spherically unilamellar microstructures with entrapment efficiency of 79.7 ± 3.9%, mean particle size of 121.6 ± 52.9 nm, and zeta potential of -5.87 mV. OMT-LIP significantly increased the accumulation of OMT in the fibrotic liver with an 11.5-fold greater AUC than OMT solution in the dimethylnitrosamine (DMN)-induced hepatic fibrosis animals. OMT-LIP could be a potential strategy to improve treatment outcomes for hepatic fibrosis, showing the protective effects to mice given CCl4 and the enhanced therapeutics to mice with either DMN or CCl4-induced hepatic fibrosis.

    Operative treatment of patients with Raynaud's Syndrome is rarely used, and is recommended by most authors only in the case of disthrophic changes or so advanced symptoms, which disturb normal social and daily life. Recently, thoracoscopic sympathectomy is applied more frequently. The aim of this study was to assess the usefulness of thoracoscopic sympathectomy by the presentation of early and long-term outcome of 43 thoracic and eight lumbar sympathectomies performed in 41 patients with Raynaud's Syndrome. Transpleural posterio-lateral thoracotomy was performed 29 times in 27 patients, whereas thoracoscopic sympatectomy 14 times in 8 patients. Surgical techniques, early and long-term results were discussed. Based on early and long-term outcome, there were no significant differences between applied surgical techniques. Moreover, thoracoscopic sympathectomy was safe in the aspect of a short duration as well as good therapeutic and cosmetic effect of the procedure. It should be applied instead of others, so far used methods, with the exception of patients with massive pleural adhesions, which need thoracotomy.

    Three levels of sensorimotor control within the central nervous system (CNS) can be distinguished. During the neonatal stage, general movements and primitive reflexes are controlled at the spinal and brain stem levels. Analysis of the newborn's spontaneous general movements and the assessment of primitive reflexes is crucial in the screening and early recognition of a risk for abnormal development. Following the newborn period, the subcortical level of the CNS motor control emerges and matures mainly during the first year of life. This allows for basic trunk stabilization, a prerequisite for any phasic movement and for the locomotor function of the extremities. At the subcortical level, orofacial muscles and afferent information are automatically integrated within postural-locomotor patterns. Finally, the cortical (the highest) level of motor control increasingly becomes activated. Cortical control is important for the individual qualities and characteristics of movement. It also allows for isolated segmental movement and relaxation. A child with impaired cortical motor control may be diagnosed with developmental dyspraxia or developmental coordination disorder. Human ontogenetic models, i.e., developmental motor patterns, can be used in both the diagnosis and treatment of locomotor system dysfunction. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Epilepsy is a neurologic disorder with major social impact. Surgery is a valuable option in patients who are not responding to antiepileptic drugs. The literature reports demonstrate that a proportion ranging from 40 to 100% of patients with epilepsy achieve seizure remission after surgery. A presurgical evaluation (clinical and instrumental) must be performed in all patients with drug-resistant epilepsy to assess their suitability for surgical intervention. Health Technology Assessment (HTA) represents a modern approach to the analysis of technologies used for health care. HTA could be considered a bridge between science that produces evidence and the decisions that can be taken on the basis of that evidence at different levels of the health care system. The aim of this study is the HTA of epilepsy surgery including clinical, ethical, social, and economic features. The present study includes an analysis of the diagnostic and surgical workup performed at the Italian centers for the diagnosis and treatment of drug-resistant epilepsy (DRE). The study includes the following issues: (1) social, ethical impact, and costs of the disease; (2) clinical results, efficacy, and safety of surgery; (3) ethics and quality of life after surgery; and (4) economic impact and productivity regained after surgery. The cost of managing a patient with DRE included in the presurgical study was estimated by the bottom-up microcosting technique that starts from a detailed collection of data on consumption of resources and full costing. The phases analyzed were (1) noninvasive diagnostic workup; (2) neurosurgical intervention; and (3) follow-up. The literature reports indicate epilepsy surgery as an effective treatment both on clinical results and on ethical, social, and quality of life aspects. The workup including the noninvasive presurgical study followed by surgery has a total cost of €20,827. Management of short-term follow-up increases the overhead to €22,291 at the first year

    These practice parameters describe the assessment and treatment of early-onset bipolar disorder based on scientific evidence regarding diagnosis and effective treatment and on the current state of clinical practice. Given the paucity of research on bipolar disorder in children and adolescents, many of the treatment recommendations are drawn from the adult literature. Although the same diagnostic criteria are used as for adults, youth may differ with regard to the developmental presentation of symptoms and comorbid psychiatric disorders. Treatment involves the combination of pharmacotherapy and adjunctive psychosocial interventions. Antimanic agents (primarily lithium or valproic acid) are the mainstays of pharmacotherapy. The treatment focuses on (1) amelioration of acute symptoms; (2) the prevention of relapse; (3) the reduction of long-term morbidity; and (4) the promotion of long-term growth and development. These parameters were approved by Council of the American Academy of Child and Adolescent Psychiatry on June 5, 1996.

    Introduction: The commonest mitral regurgitation etiologies are degenerative (60%), rheumatic post-inflammatory, 12%) and functional (25%). Due to the large number of patients with acute MI, the incidence of ischaemic MR is also high. Ischaemic mitral regurgitation is a complex multifactorial disease that involves left ventricular geometry, the mitral annulus, and the valvular/subvalvular apparatus. Ischaemic mitral regurgitation is an important consequence of LV remodeling after myocardial infarction. Research Objectives: The objective of this study is to determine the role of echocardiography in detecting and assessment of mitral regurgitation mechanism, severity, impact on treatment strategy and long term outcome in patients with myocardial infarction during the follow up period of 5 years. Also one of objectives to determine if the absence or presence of ischaemic MR is associated with increased morbidity and mortality in patients with myocardial infarction. Patients and methods: The study covered 138 adult patients. All patients were subjected to echocardiography evaluation after acute myocardial infarction during the period of follow up for 5 years. The patients were examined on an ultrasound machine Philips iE 33 xMatrix, Philips HD 11 XE, and GE Vivid 7 equipped with all cardiologic probes for adults and multi-plan TEE probes. We evaluated mechanisms and severity of mitral regurgitation which includes the regurgitant volume (RV), effective regurgitant orifice area (EROA), the regurgitant fraction (RF), Jet/LA area, also we measured the of vena contracta width (VC width cm) for assessment of IMR severity, papillary muscles anatomy and displacement, LV systolic function ± dilation, LV regional wall motion abnormality WMA, LV WMI, Left ventricle LV remodeling, impact on treatment strategy and long term mortality. Results: We analyzed and follow up 138 patients with previous (>16 days) Q-wave myocardial infarction by ECG who underwent TTE and TEE

    There is an increase demand for clean water sources in Saudi Arabia and, yet, renewable water resources are very limited. This has forced the authorities to explore deep groundwater which is known to contain large concentrations of radionuclides, mainly radium isotopes. Lately, there has been an increase in the number of water treatment plants (WTPs) around the country. In this study, a radiological assessment of a WTP in Saudi Arabia was performed. Raw water was found to have total radium activity of 0.23 Bq/L, which exceeds the international limit of 0.185 Bq/L (5 pCi/L). The WTP investigated uses three stages of treatment: flocculation/sedimentation, sand filtration and reverse osmosis. The radium removal efficiency was evaluated for each stage and the respective values were 33%, 22% and 98%. Moreover, the activity of radium in the solid waste generated from the WTP in the sedimentation and sand filtrations stages were measured and found to be 4490 and 6750 Bq/kg, respectively, which exceed the national limit of 1000 Bq/kg for radioactive waste. A radiological assessment of the air inside the WTP was also performed by measuring the radon concentrations and dose rates and were found in the ranges of 2–18 Bq/m{sup 3} and 70–1000 nSv/h, respectively. The annual effective dose was calculated and the average values was found to be 0.3 mSv which is below the 1 mSv limit. - Highlights: • Radiological assessment of groundwater treatment plant was performed. • Radium Removal efficiency was calculated for different stages during water treatment. • Radium concentrations in sludge were measured and found to exceed the national limit for radioactive waste. • Air radon concentrations and dose rates were monitored in the water treatment plant. • The Reverse Osmosis (RO) unit was found to record the highest air radon concentrations and dose rates.

    A comprehensive system characterisation was performed of the Eckert & Ziegler BEBIG GmbH MultiSource High Dose Rate (HDR) brachytherapy treatment unit with an (192)Ir source. The unit is relatively new to the UK market, with the first installation in the country having been made in the summer of 2009. A detailed commissioning programme was devised and is reported including checks of the fundamental parameters of source positioning, dwell timing, transit doses and absolute dosimetry of the source. Well chamber measurements, autoradiography and video camera analysis techniques were all employed. The absolute dosimetry was verified by the National Physical Laboratory, UK, and compared to a measurement based on a calibration from PTB, Germany, and the supplied source certificate, as well as an independent assessment by a visiting UK centre. The use of the 'Krieger' dosimetry phantom has also been evaluated. Users of the BEBIG HDR system should take care to avoid any significant bend in the transfer tube, as this will lead to positioning errors of the source, of up to 1.0 mm for slight bends, 2.0 mm for moderate bends and 5.0 mm for extreme curvature (depending on applicators and transfer tube used) for the situations reported in this study. The reason for these errors and the potential clinical impact are discussed. Users should also note the methodology employed by the system for correction of transit doses, and that no correction is made for the initial and final transit doses. The results of this investigation found that the uncorrected transit doses lead to small errors in the delivered dose at the first dwell position, of up to 2.5 cGy at 2 cm (5.6 cGy at 1 cm) from a 10 Ci source, but the transit dose correction for other dwells was accurate within 0.2 cGy. The unit has been mechanically reliable, and source positioning accuracy and dwell timing have been reproducible, with overall performance similar to other existing HDR equipment. The unit is capable of high

    Agomelatine is an antidepressant drug that is a synthetic analogue of the hormone melatonin. It stimulates the activity of melatonin MT(1) and MT(2) receptors and inhibits the activity of serotonin 5HT(2C) receptor subtypes. The objective of this article is to critically review and evaluate the benefits and risks of agomelatine for the treatment of major depression. The published literature through April 2011 for articles relating to agomelatine, together with unpublished data on agomelatine available from the European Medicines Agency, the US FDA, US ClinicalTrials.gov and the Novartis Clinical Trial Results Database are reviewed. The antidepressant efficacy of agomelatine has been systematically assessed in ten short-term, placebo-controlled studies and three longer-term, placebo-controlled, relapse prevention studies. Five short-term trials demonstrated clinically modest, but statistically significant, benefits over placebo, although two of these studies reported opposite effects for 25 mg versus 50 mg doses. The other five short-term trials did not find agomelatine more effective than placebo, but in two of these studies the active control drug was more effective than placebo. A meta-analysis of six European trials demonstrated a small, statistically significant, marginally clinically relevant difference in efficacy favouring agomelatine over placebo. The only placebo-controlled study in elderly patients did not demonstrate a significant benefit for agomelatine. Agomelatine was shown to be more effective than placebo in one of three relapse prevention studies. Agomelatine was generally well tolerated compared with placebo. Its adverse effect profile is different to that of other antidepressant drugs, but its overall tolerability in studies with other antidepressants as active control drugs did not appear to be substantially better than the controls. Agomelatine is contraindicated in patients with impaired liver function and in patients taking drugs that

    To determine the diagnostic benefit of volume perfusion computed tomography (VPCT) at end of treatment for response assessment in lymphoma patients. Seventy-five patients with different lymphoma subtypes were included: 50/75 patients had residual masses at end of treatment, 26/50 patients underwent VPCT at baseline and at end of treatment, and 24/50 patients only had end-of-treatment VPCTs. We evaluated the size of the main lymphoma mass, its blood flow (BF), blood volume (BV) and k-trans, calculated ratios (baseline and end of treatment) as well as sensitivity/specificity/negative (NPV)/positive predictive values (PPV). For VPCT at end of treatment, a cutoff threshold between responders and non-responders was calculated. For patients undergoing VPCT at baseline and end of treatment, reduction in size, BF, BV and k-trans was significant (P < 0.001). Identification of non-response was reached at: <53 % reduction in size (sensitivity/specificity/accuracy/PPV/NPV of 88.89 %/62.5 %/80.77 %/84.21 %/71.43 %), <15 % reduction of BF (sensitivity/specificity/accuracy/PPV/NPV of 100 %/37.5 %/80.77 %/0.26 %/100 %), or <45 % reduction of k-trans (sensitivity/specificity/accuracy/PPV/NPV of 88.89 %/75 %/84.62 %/88.89 %/75 %). In the subgroup undergoing VPCT at end of treatment, BF >18.51 ml/100 ml indicated non-responsiveness (sensitivity 92.86 %, specificity 72.73 %, accuracy 84 %, PPV 81.25 %, NPV 88.89 %). VPCT seems adequate for assessment of lymphoma response at end of treatment. The degree of residual lymphoma perfusion at end of treatment helps to identify patients likely to remain in remission 1 year after completion of therapy. (orig.)

    The Risk Need Responsivity (RNR) principles (Andrews & Bonta, 2010) dictate that higher risk sex offenders should receive more intensive treatment. The present study investigates how clinically based treatment assignment relates to risk level in a sex offender sample from The Netherlands. Correlational analyses served to identify sources of mismatches: that is, variables differing significantly in their relation between treatment selection and risk level. Our study sample consisted of 194 convicted rapists and 214 convicted child molesters. All participants' criminal files were retrospectively coded in terms of the items of the STATIC-99R, PCL: SV, and SVR-20. A low to moderate correlation was observed between clinical treatment selection and actuarial risk levels. A substantial part of the sex offenders, especially child molesters, received overly intensive treatment and another substantial part, especially rapists, received treatment of lesser intensity than indicated by their risk levels. General violent and antisocial risk factors seemed to be underemphasized in the clinical evaluation of sex offenders, especially rapists. A negative attitude toward intervention was negatively associated with clinical treatment selection. It is concluded that clinical treatment selection leads to an insufficient match between risk level and treatment level and systematic use of validated structured risk assessment instruments is necessary to ensure optimal adherence to the risk principle.

    Full Text Available The findings of the research project that encompasses 137 small municipal wastewater treatment plants (WWTP are presented in the paper. The source data for the research is the official statistical reporting according to Form № 2-TP (water submitted in 2010, as well as the information on completed and approved projects that demonstrate admissible discharge standards. The method of environmental assessment of barrier capabilities of municipal WWTP based on six major indicators (TSS, BOD, N-NH4+, N-NO2-, N-NO3-, P-PO43- is proposed to ensure compliance with the present-day environmental standards. The maximal likelihood of incompliance with the pre-set standards is demonstrated by phosphorus phosphate (97 %, ammonium nitrogen (95 % and nitrite nitrogen (79 %. The substances that demonstrate their maximal excessive content in the wastewater include phosphorus phosphate (its content exceeds the admissible st
