Introduction Surgical treatment of hemorrhoids is still a dilemma. New techniques have been developed leading to a lower rate of postoperative pain; however, they are associated with a greater likelihood of recurrence. Aim To review current indications as well as the results and complications of the main techniques currently used in the surgical treatment of hemorrhoidal disease. Methods A systematic search of the published data on the options for treatment of hemorrhoids up to December 2012 was conducted using Medline/PubMed, Cochrane, and UpToDate. Results Currently available surgical treatment options include procedure for prolapse and hemorrhoids (PPH), transanal hemorrhoidal dearterialization (THD), and conventional hemorrhoidectomy techniques. Excisional techniques showed similar results regarding pain, time to return to normal activities, and complication rates. PPH and THD were associated with less postoperative pain and lower complication rates; however, both had higher postoperative recurrence rates. Conclusion Conventional surgical techniques yield better long-term results. Despite good results in the immediate postoperative period, PPH and THD have not shown consistent long-term favorable results. PMID:24676303

2012-11-01

Urethral dilatation and direct visual internal urethrotomy (DVIU) are widely used minimally invasive options to manage men with urethral strictures. Advances in open urethroplasty with better long-term cure rates have fuelled the continuing debate as to which treatment is best for primary and recurrent urethral strictures. We reviewed recent literature to identify contemporary practice of urethral dilatation and DVIU and the long-term outcome of these procedures. Systematic literature search for the period January 2010 to December 2011 showed that urethral dilatation and DVIU remain frequently used treatment options as confirmed by surveys of urologists in the USA and the Netherlands. Multiple reports of laser DVIU confirm the safety of this approach but long-term data were lacking. Stricture free rates from urethra dilatation and DVIU vary from 10 to 90% at 12 months, although adjunctive intermittent self-dilatation can reduce time to recurrence. Although quality-of-life benefit appears good in the short term, repeated procedures may harm sexual function in the long-term. Urethral dilatation and DVIU remain widely used in urethral stricture management but high-level comparative evidence of benefit and harms against urethroplasty in the short and long-term is still lacking.

Opioid addiction is associated with excess mortality, morbidities, and other adverse conditions. Guided by a life-course framework, we review the literature on the long-term course of opioid addiction in terms of use trajectories, transitions, and turning points, as well as other factors that facilitate recovery from addiction. Most long-term follow-up studies are based on heroin addicts recruited from treatment settings (mostly methadone maintenance treatment), many of whom are referred by the criminal justice system. Cumulative evidence indicates that opioid addiction is a chronic disorder with frequent relapses. Longer treatment retention is associated with a greater likelihood of abstinence, whereas incarceration is negatively related to subsequent abstinence. Over the long term, the mortality rate of opioid addicts (overdose being the most common cause) is about 6 to 20 times greater than that of the general population; among those who remain alive, the prevalence of stable abstinence from opioid use is low (less than 30% after 10-30 years of observation), and many continue to use alcohol and other drugs after ceasing to use opioids. Histories of sexual or physical abuse and comorbid mental disorders are associated with the persistence of opioid use, whereas family and social support, as well as employment, facilitates recovery. Maintaining opioid abstinence for at least five years substantially increases the likelihood of future stable abstinence. Recent advances in pharmacological treatment options (buprenorphine and naltrexone) include depot formulations offering longer duration of medication; their impact on the long-term course of opioid addiction remains to be assessed.

Second malignant neoplasms, cardiovascular disease, neurotoxicity and ototoxicity, pulmonary complications, hypogonadism, and nephrotoxicity are potentially life-threatening long-term complications of testicular cancer and its therapy. This article describes the pathogenesis, risks, and management of these late effects experienced by long-term testicular cancer survivors, who are defined as individuals who are disease free 5 years or more after primary treatment. Testicular cancer survivors should follow applicable national guidelines for cancer screening and management of cardiovascular disease risk factors. In addition, health care providers should capitalize on the time of cancer diagnosis as a teachable moment to introduce and promote lifestyle changes. Copyright © 2015 Elsevier Inc.

To determine the short-term and long-term treatment-effects of botulinum toxin type A in simple motor tics, we analyzed 15 consecutive patients (18 tics) with simple motor tics that were treated every 3 months with injections of BTX-A. Efficacy (rated on a 4-level scale) and duration of effect of the first 2 and last 2 (if treated 5 times or more) treatments were recorded, as well as latency of response, changes of premonitory urges (PMUs) and possible side effects. Total number of treatments for each tic varied from 2 to 50 (mean 11, median 6). In 16 of 18 tics (89%) short-term efficacy was reported successful (good or moderate). Long-term efficacy was reported in 12 tics of which 11 showed similar or even increased beneficial effects. Premonitory urge (PMU) was reported in 8 patients (53%). PMU, if present, lessened or disappeared after treatment with BTX-A. A permanent remission of the treated tic was seen in 3 patients with a maximum follow-up of 10 years. BTX-A appears a safe and effective treatment for simple motor tics and retains its efficacy after long-term treatment. BTX may also induce permanent remission of the treated tics and effects of BTX are not restricted to merely motor behaviour.

Consequences for option pricing of a long memory in volatility

The economic consequences of a long memory assumption about volatility are documented, by comparing implied volatilities for option prices obtained from short and long memory volatility processes. Numerical results are given for options on the S&P 100 index from 1984 to 1998, with lives up to two years. The long memory assumption is found to have a significant impact upon the term structure of implied volatilities and a relatively minor impact upon smile effects. These conclusions are importa...

[Necessary and unnecessary treatment options for hemorrhoids].

2014-12-01

Up to one third of the general population suffers from symptoms caused by hemorrhoids. Conservative treatment comes first unless the patient presents with an acute hemorrhoidal prolapse or a thrombosis. A fiber enriched diet is the primary treatment option, recommended in the perioperative period as well as a long-term prophylaxis. A timely limited application of topical ointments or suppositories and/or flavonoids are further treatment options. When symptoms persist interventional procedures for grade I-II hemorrhoids, and surgery for grade III-IV hemorrhoids should be considered. Rubber band ligation is the interventional treatment of choice. A comparable efficacy using sclerosing or infrared therapy has not yet been demonstrated. We therefore do not recommend these treatment options for the cure of hemorrhoids. Self-treatment by anal insertion of bougies is of lowrisk and may be successful, particularly in the setting of an elevated sphincter pressure. Anal dilation, sphincterotomy, cryosurgery, bipolar diathermy, galvanic electrotherapy, and heat therapy should be regarded as obsolete given the poor or missing data reported for these methods. For a long time, the classic excisional hemorrhoidectomy was considered to be the gold standard as far as surgical procedures are concerned. Primary closure (Ferguson) seems to be superior compared to the "open" version (Milligan Morgan) with respect to postoperative pain and wound healing. The more recently proposed stapled hemorrhoidopexy (Longo) is particularly advisable for circular hemorrhoids. Compared to excisional hemorrhoidectomy the Longo-operation is associated with reduced postoperative pain, shorter operation time and hospital stay as well as a faster recovery, with the disadvantage though of a higher recurrence rate. Data from Hemorrhoidal Artery Ligation (HAL)-, if appropriate in combination with a Recto-Anal Repair (HAL/RAR)-, demonstrates a similar trend towards a better tolerance of the procedure at the

Dienogest in long-term treatment of endometriosis

Full Text Available Adolf E SchindlerInstitute for Medical Research and Education, Essen, GermanyAbstract: Endometriosis is a chronic disease primarily affecting women of childbearing age, in which endometriotic lesions form outside the uterus, typically leading to painful symptoms, fatigue, and infertility. The symptoms of endometriosis may cause significant impairment in quality of life and represent a substantial economic burden to patients, families, and society. There is no cure for endometriosis; management consists of alleviating pain and other symptoms, reducing endometriotic lesions, and improving quality of life. Recurrence after surgical intervention is common, while the clinical evidence to support the efficacy and safety of many medications currently used in endometriosis is limited. Dienogest is an oral progestin that has been investigated extensively in the treatment of endometriosis in two clinical programs performed in Europe and Japan, including dose-ranging, placebo-controlled, active comparator-controlled, and long-term (up to 65 weeks studies. These studies demonstrated that dienogest 2 mg daily effectively alleviates the painful symptoms of endometriosis, reduces endometriotic lesions, and improves indices of quality of life. Dienogest showed a favorable safety and tolerability profile in these studies, with predictable adverse effects, high rates of patient compliance, and low withdrawal rates. This review article describes the clinical trial evidence that characterizes the efficacy and safety of dienogest in endometriosis, including two studies characterizing dienogest in long-term use. The relevance of these findings to the management of endometriosis in clinical practice is discussed.Keywords: dienogest, endometriosis, progestins, long-term treatment, quality of life, symptoms, pain

Uranium enrichment: investment options for the long term

International Nuclear Information System (INIS)

Anon.

1983-01-01

The US government supplies a major portion of the enriched uranium used to fuel most of the nuclear power plants that furnish electricity in the free world. As manager of the US uranium enrichment concern, the Department of Energy (DOE) is investigating a number of technological choices to improve enrichment service and remain a significant world supplier. The Congress will ultimately select a strategy for federal investment in the uranium enrichment enterprise. A fundamental policy choice between possible future roles - that of the free world's main supplier of enrichment services, and that of a mainly domestic supplier - will underlie any investment decision the Congress makes. The technological choices are gaseous diffusion, gas centrifuge, and atomic vapor laser isotope separation (AVLIS). A base plan and four alternatives were examined by DOE and the Congressional Budget Office. In terms of total enterprise costs, Option IV, ultimately relying on advanced gas centrifuges for enrichment services, would offer the most economic approach, with costs over the full projection period totaling $123.5 billion. Option III, ultimately relying on AVLIS without gas centrifuge enrichment or gaseous diffusion, falls next in the sequence, with costs of $128.2 billion. Options I and II, involving combinations of the gas centrifuge and AVLIS technologies, follow closely with costs of $128.7 and $129.6 billion. The base plan has costs of $136.8 billion over the projection period. 1 figure, 22 tables

Full Text Available Charalampos Papagoras, Paraskevi V Voulgari, Alexandros A DrososRheumatology Clinic, Department of Internal Medicine, Medical School, University of Ioannina, Ioannina, GreeceAbstract: Adalimumab, a fully humanized monoclonal antibody against tumor necrosis factor-alpha (TNFα, has been evaluated in various randomized placebo-controlled trials in rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and juvenile idiopathic arthritis. In the short time frame of these trials adalimumab has been shown to be effective in reducing disease activity, slowing radiographic disease progression and improving patients’ quality of life, while at the same time demonstrating an acceptable safety profile. Furthermore, release of adalimumab on the market, prospective observational studies, as well as open-label extensions of the original double-blind trials have provided experience and data about the long-term efficacy and safety of the drug. Initial effectiveness, in terms of reducing disease activity, is sustained, while in most cases patients treated with adalimumab experienced a slower radiographic progression and consequently less disability and improved health-related quality-of-life outcomes. Moreover, long-standing treatment of thousands of patients with adalimumab outside the controlled context of clinical trials was not related to new safety signals, with the most common adverse events being respiratory infections. The most common serious adverse events seem to be tuberculosis reactivation, while a putative association with malignant lymphoma development is not yet proven. Besides, both of these adverse reactions pertain to the whole TNFα blocker group. In conclusion, adalimumab is a safe and effective option for the treatment of patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and juvenile idiopathic arthritis.

parasitic necrosis died because it was impossible to control systemic sepsis (3% hospital lethality). Curative surgery for AE is feasible if the parasitic mass is removable entirely. The earlier the stage, the more frequent is R0 resectability. The observance of a minimal safe distance increases the rate of R0 resections. The benefit of palliative surgery is uncertain due to favorable long-term results of medical treatment alone. However, necrotic tissue is at risk of bacterial superinfection, which can cause life-threatening sepsis. Palliative surgery is an option to treat complications, which could not be managed otherwise.

Full Text Available Eva Ceskova, Petr Silhan Department of Psychiatry, University Hospital Ostrava, Ostrava, Czech Republic Abstract: In spite of tremendous development in central nervous system research, current treatment is suboptimal, especially in severe mental disorders. In medicine, there are two main methods of improving the health care provided: seeking new treatment procedures and perfecting (optimizing the existing ones. Optimization of treatment includes not only practical tools such as therapeutic drug monitoring but also implementation of general trends in the clinical practice. New pharmacological options include new more sophisticated forms of monoaminergic drugs, old drugs rediscovered on the base of a better understanding of pathophysiology of mental illnesses, and drugs aimed at new treatment targets. In depression, treatment resistance to antidepressive pharmacotherapy represents one of the most important clinical challenges. Switching to monotherapy with new multimodal/multifunctional antidepressants and augmentation with new atypical antipsychotics (aripiprazole and brexpiprazole may be promising options. Further, current evidence supports utility and safety of adjunctive treatment of nutraceuticals. Novel approaches being studied include ketamine and opioids. Recent advances in technology and emerging knowledge about dysfunctional brain circuits and neuroplasticity have led to the development of different new neuromodulation techniques usually used as add-on therapy. Antipsychotics are still the cornerstone of the current treatment of schizophrenia. Two new partial dopamine agonists, brexpiprazole and cariprazine, are now available in addition to aripiprazole. Although the mechanisms of action are similar, the two agents differ in terms of their pharmacodynamic profiles. Further, two new formulations of long-acting injections of second-generation antipsychotics (aripiprazole lauroxil and 3-month paliperidone palmitate were introduced into

Etanercept provides an effective, safe and flexible short- and long-term treatment regimen for moderate-to-severe psoriasis: a systematic review of current evidence.

The treatment of psoriasis requires long-lasting intervention. Conventional treatments for psoriasis comprise topical, phototherapeutic and systemic modalities, such as methotrexate or cyclosporine. Biological therapies are advocated by treatment guidelines for the use in moderate-to-severe psoriasis, when conventional treatments have failed, are contraindicated or are associated with severe adverse events. Etanercept is an anti-TNF recombinant fusion protein that has emerged as a standard biologic treatment option for moderate-to-severe psoriasis. The present review summarizes data from pivotal and post-marketing randomized controlled etanercept trials to treat moderate-to-severe psoriasis for 24 weeks and longer. During the first 12 weeks, etanercept can be administered in different dosing regimens: 50 mg twice weekly (BIW) and 50 mg once weekly. Although both regimens are effective, it has been shown that the 50 mg BIW dosage leads to higher response rates at week 24. In addition, after 24 weeks' treatment etanercept provides the unique possibility of continuous or intermittent long-term treatment programmes. The medium- to long-term efficacy of etanercept was consistent, regardless of whether etanercept therapy was interrupted or continuous. Taking the chronic nature of psoriasis into account, this flexibility in dosing regimen bestows a key advantage in facilitating individualisation of long-term treatment according to patient needs.

Acromegaly is a rare, slowly progressive disorder resulting from excessive growth hormone (GH) production by a pituitary somatotroph tumor. The objective of this study was to examine acromegaly treatment outcomes during long-term care at a specialized pituitary center in patients presenting with lack of biochemical control. Data came from an acromegaly registry at the Cedars-Sinai Medical Center Pituitary Center (center). Acromegaly patients included in this study were those who presented biochemically-uncontrolled for care at the center. Biochemical control status, based on serum insulin-like growth factor-1 values, was determined at presentation and at study end. Patient characteristics and acromegaly treatments were reported before and after presentation by presenting treatment status and final biochemical control status. Data on long-term follow-up were recorded from 1985 through June 2013. Seventy-four patients presented uncontrolled: 40 untreated (54.1%) and 34 (45.9%) previously-treated. Mean (SD) age at diagnosis was 43.2 (14.7); 32 (43.2%) were female patients. Of 65 patients with tumor size information, 59 (90.8%) had macroadenomas. Prior treatments among the 34 previously-treated patients were pituitary surgery alone (47.1%), surgery and medication (41.2%), and medication alone (11.8%). Of the 40 patients without prior treatment, 82.5% achieved control by study end. Of the 34 with prior treatment, 50% achieved control by study end. This observational study shows that treatment outcomes of biochemically-uncontrolled acromegaly patients improve with directed care, particularly for those that initially present untreated. Patients often require multiple modalities of treatment, many of which are offered with the highest quality at specialized pituitary centers. Despite specialized care, some patients were not able to achieve biochemical control with methods of treatment that were available at the time of their treatment, showing the need for additional

Fibroids (leiomyoma) are the most frequent benign tumors of the uterus during female reproductive age. In the case of clinical symptoms, uterine artery embolization (UAE) is a well established treatment option for symptomatic fibroids, resulting in promising long-term results. In order to estimate long-term success after UAE, reduction of fibroids and uterus volume is less important than complete improvement and disappearance of fibroid-related symptoms. In addition to a high technical success rate and a low perioperative complication rate, UAE results in high short-term and long-term patient satisfaction (>87%) and improvement of symptoms (>81%). Candidates for UAE should be informed about potential reinterventions in terms of repeated UAE (up to 18% of cases) or surgical treatment options. (orig.)

Im Vordergrund der Abschaetzung eines lang andauernden Therapieerfolgs nach UAE stehen weniger die Volumenreduktion eines dominanten Myoms bzw. des gesamten Uterus nach der Behandlung, sondern vielmehr die Besserung oder das voellige Verschwinden der von der Patientin initial vor der UAE angegebenen (myombedingten) Beschwerden. Neben einer hohen technischen Erfolgsrate und geringen perioperativen Komplikationsrate fuehrt die fachkundig durchgefuehrte UAE sowohl im Kurz- als auch Langzeitverlauf zu einem hohen Mass an Patientenzufriedenheit (>87%), verbunden mit einer deutlichen Symptombesserung (>81%).

2015-01-01

Monoclonal anti-IgE antibody omalizumab is a promising therapeutic option in patients with chronic urticaria (CU) resistant to non-sedating H1-antihistamines (nsAH). However, data about its long-term efficacy and safety are still scant. We retrospectively analysed the clinical course of patients with severe recalcitrant CU that were treated in our department with omalizumab for a period greater than 24 months. Seven patients (six females, median 43 years) treated for a median of 35 months have been evaluated. Before treatment, all suffered from persistent symptoms despite receiving high doses of nsAH [4×/day], leukotriene antagonists and prednisolone (10-30 mg/day for a median duration of 48 months). Response to treatment was assessed using urticaria activity score (UAS) and a combined symptom/medication score. There was a complete remission of disease in four patients after the first dose of omalizumab. Before the 5th administration, all patients had a UAS of 0. We found a significant improvement in UAS between pre-treatment and first dose (p=0.017) and a gradual decrease in the symptom/medication score over the course of the first five administrations. Tapering of prednisolone was possible in all patients. Administration intervals were gradually increased, although all experienced resurgence of symptoms in cycles greater than six weeks. There were no reported adverse reactions attributable to the drug. Omalizumab was a safe and effective corticosteroid alternative for maintaining long-term remission of symptoms in these patients. Treatment intervals required individual patient-by-patient determination. The drug did not seem to alter the natural history of the disease. Copyright © 2013 SEICAP. Published by Elsevier Espana.

Introducing short term flexibility in the EU ETS to assure its long-term credibility: a multi-criteria analysis of policy options. Climate Report no. 45

International Nuclear Information System (INIS)

Desai, Zuheir; Alberola, Emilie; Berghmans, Nicolas

2014-07-01

It is now well established that the European Union Emissions Trading Scheme (EU ETS) needs to be reformed. After more than 18 months of discussions, the EU Commission disclosed, in its communication published in January 2014 on 'A policy framework for climate and energy in the period from 2020 to 2030', its legislative proposal of a market stability reserve (MSR) in the EU ETS. This measure, that should be implemented from the next compliance period (2021-2028) onwards, would reduce the surplus of allowances growing since 2008 and improve the ETS's resilience to external shocks by automatically adjusting the supply of allowances to be auctioned. The operation of this MSR would be determined by predefined rules that, once agreed on, leave no discretion to either the Commission or Member States. The choice of the EU Commission to introduce a reserve in the EU ETS is very innovative even if other emissions trading schemes have already introduced a reserve in their design. Initial discussions began in March and April 2014 in the European Parliament and Council and the question of whether the MSR really improves the functioning of the EU ETS in the long term is still being debated. What other structural mechanism would be better suited in improving the long-term effectiveness of the EU ETS? To help in the decision making process, this report presents a multi-criteria analysis. Without prejudging their political support, five policy options have been evaluated that would introduce some flexibility in the EU ETS and potentially ensure its long-term credibility: an auction reserve price, permit supply rules that target a certain corridor of surplus (market stability reserve), permit supply rules that target economic activity, permit supply rules that target overlap with other energy policies and a rolling emissions cap. The assessment of these five policy options was based on a criteria tree and on the EU ETS experts' panel's votes that expressed

The aim of this study is to make an evaluation of the effectiveness of long-term outpatient treatment for addiction on the basis of abstinence, cognitive functions, and changes in personality structure. This is a prospective cohort study of 259 patients with registration of the German core data set "addiction", a 12-month follow-up and neuropsychological testing (personality inventory, intelligence and cognitive functions). One year after the end of the long-term treatment we see an abstinence rate (DGSS4) of 57.5 %. The most substantial factors in abstinence are the participation in a self-help-group (β = 0.734, p addiction seem to show its high effectiveness in terms of abstinence and processing of drug structures. The cognitive functions could increase. This could be determinate of a condition for the conservation and restoration of working capacity. Further studies should differentiate the effect of insight into the dependency structure from the abstinence as an specific or unspecific effect. © Georg Thieme Verlag KG Stuttgart · New York.

Current ocular GvHD (oGvHD) treatments are suboptimal. We investigated the safety and efficacy of long-term continuous treatment with autologous platelet lysate (PL) drops in patients with oGvHD Dry Eye Syndrome (DES) score 2-3 refractory to topical conventional therapy. Ophthalmic evaluation was performed at 6 month intervals. Symptoms were assessed using the Glaucoma Symptom Scale (GSS). Patients were defined 'responders' when showing a reduction at least one grade on National Institutes of Health Eye Score from baseline at the 6 month visit. Thirty-one patients were included, and 16 (51%) completed 36 months of follow-up (range 6.5-72.7). At 6 months all patients were classified as responders: median GSS symptom score decreased from 70 to 41 (33 at 36 months), median GSS function score reduced from 68 to 46 (33 at 36 months) (all P<0.001). Median Tear Break Up Time improved from 3 to 6 s after 6 months and was maintained over time. All signs improved at 6 and 36 months (clinical and statistical significance). No severe adverse events occurred. Long-term treatment with PL drops is secure and effective for oGvHD and can be an efficient therapy option from initial stages of oGvHD to prevent permanent ocular impairment and improving quality of life.

Real option valuation of free destination in long-term liquefied natural gas supplies

International Nuclear Information System (INIS)

Yepes Rodriguez, Ramon

2008-01-01

This paper presents a real option model for the valuation of destination flexibility in long-term LNG supplies. Stochastic price dynamics in the different markets is modelled through geometric Brownian motion processes. Mean reversion is considered as well as correlation between markets, but instead of the usual correlation in return shocks, a price convergence term is introduced representing the arbitrage streams between markets. Model parameters are estimated from market data on LNG prices by maximum log-likelihood. The goodness of the fit for the proposed model is tested as well as for two alternative models. Confidence intervals for the parameters are given. Results for the model are calculated by Monte Carlo simulation. Frequency distributions for the main results are plotted. The effect of the main parameters of the model is studied (i.e. price volatilities, price convergence, initial prices in the markets, mean reversion, extra transportation costs, number of alternative markets). The value of destination flexibility is found to be an important share of the value of LNG

Introduction Extracorporeal shock wave lithotripsy (ESWL) is a well-known and successful treatment modality. In addition, it can be used in premature infants. ESWL is used to treat kidney and ureter stones in children. However, although it is a preferred noninvasive treatment in that setting, there is debate about its long-term effects on growing kidneys in children. Objectives To investigate the long-term effects of pediatric ESWL on renal function in light of updated literature. Methods PubMed and Medline were searched for studies on ESWL in a pediatric population with keywords including efficacy, child, kidney calculi, ureter calculi, lithotripsy, injury, vascular trauma, and shock waves. The research was limited to the English literature during a period from 1980 to 2014. In total, 3,000 articles were evaluated, but only 151 papers were considered. Only the manuscripts directly related to the reviewed subjects were included in the current study. Results However, the acute effects of ESWL in kidney are well-described. Although there are limited studies on the long-term effects of ESWL in children, there is a widespread opinion that ESWL is not affecting renal functions in the long-term. Conclusion ESWL is a safe, effective, and noninvasive treatment option in children. Although ESWL can cause some acute effects in the kidney, there is no long-term effect on the growing kidneys of children. PMID:24892029

The aim of this study was to determine the long-term functional outcome of kidneys in children with urolithiasis treated by means of extracorporeal shock wave lithotripsy (ESWL). The effectiveness and safety of this method in the management of pediatric urinary stone disease was also studied. This prospective study enrolled 84 children, 33 boys (age: 9.1 +/- 3.8 yrs) and 51 girls (age: 9.6 +/- 3.9 yrs), with urolithiasis who were treated using a second-generation "Siemens" Lithostar lithotriptor, in the period between 1988 and 1998. Dynamic kidney scintigraphy using (99 m)Tc-DTPA was done prior to, immediately following ESWL treatment, three months later, and again after an observation period of 12 - 67 months (38 +/- 13 months). Immediate fragmentation rate was 90 %, while the calculus clearance rate was 61 %. Glomerular filtration rate (GFR), measured by clearance of (99 m)Tc-DTPA, immediately after an ESWL treatment of 107 +/- 6 ml/min was significantly lower compared to the pretreatment value of 118 +/- 7 ml/min, but returned three months later to 121 +/- 6 ml/min, and to 131 +/- 10 ml/min at the end of the observation period. A separate analysis was performed on three groups of patients treated by ESWL: with acute calculous disease, chronic calculous disease, and chronic calculous with partial stasis. ESWL treatment in children with acute obstruction was associated with an immediate increase in GFR; however, in chronic calculous disease a decrease in GFR was found. A return of GFR to the pretreatment level was observed at the three-month control in these patients. In patients with acute stone obstruction, at 3 and 12 - 67 months after ESWL treatment, GFR of the treated kidney was found to be significantly increased compared to the pretreatment level. In contrast, in children with chronic calculous disease this increase was modest. This study has demonstrated ESWL to be an effective treatment option for urinary calculi management, which can be safely performed

To evaluate retrospectively the long-term efficacy of rituximab in patients with severe juvenile idiopathic arthritis (JIA)-associated uveitis. Eight patients (15 eyes) with severe and longstanding JIA uveitis, who had an inadequate response in controlling uveitis to one or more biologic agents including tumour necrosis factor blockers and abatacept, received rituximab therapy. Rituximab was given at a dose of 1000 mg per infusion on days 1 and 15 and then every 6 months. Clinical responses to treatment, including decrease in uveitis activity, visual acuity changes, reduction of concomitant local and systemic corticosteroid and/or immunosuppressants, and occurrence of adverse events, were assessed. Eight patients with a mean±SD age of 22.8±5.5 years were treated. The mean ocular disease duration was 17.7 years; the mean±SD follow-up time on rituximab was 44.75±4.9 months; and the mean number of rituximab infusions received was 8.75 (range 6-12). All patients achieved complete control of uveitis, but in two patients rituximab was discontinued due to inefficacy in treating arthritis. The decrease in uveitis activity was evident 4-5 months after the first infusion. Systemic corticosteroids and immunosuppressants used in association with rituximab were discontinued in five patients at the end of follow-up. None of the patients experienced visual worsening during the follow-up. No drug-related complications were encountered. Rituximab may be a promising effective treatment option for refractory uveitis associated with JIA leading to long-term quiescence of uveitis, particularly for patients who have not previously responded to other biologic therapies.

Purpose To determine the demographic, clinical, decision-making, and quality-of-life factors that are associated with treatment decision regret among long-term survivors of localized prostate cancer. Patients and Methods We evaluated men who were age ≤ 75 years when diagnosed with localized prostate cancer between October 1994 and October 1995 in one of six SEER tumor registries and who completed a 15-year follow-up survey. The survey obtained demographic, socioeconomic, and clinical data and measured treatment decision regret, informed decision making, general- and disease-specific quality of life, health worry, prostate-specific antigen (PSA) concern, and outlook on life. We used multivariable logistic regression analyses to identify factors associated with regret. Results We surveyed 934 participants, 69.3% of known survivors. Among the cohort, 59.1% had low-risk tumor characteristics (PSA decision regret: 8.2% of those whose disease was managed conservatively, 15.0% of those who received surgery, and 16.6% of those who underwent radiotherapy. Factors associated with regret on multivariable analysis included reporting moderate or big sexual function bother (reported by 39.0%; OR, 2.77; 95% CI, 1.51 to 5.0), moderate or big bowel function bother (reported by 7.7%; OR, 2.32; 95% CI, 1.04 to 5.15), and PSA concern (mean score 52.8; OR, 1.01 per point change; 95% CI, 1.00 to 1.02). Increasing age at diagnosis and report of having made an informed treatment decision were inversely associated with regret. Conclusion Regret was a relatively infrequently reported outcome among long-term survivors of localized prostate cancer; however, our results suggest that better informing men about treatment options, in particular, conservative treatment, might help mitigate long-term regret. These findings are timely for men with low-risk cancers who are being encouraged to consider active surveillance.

Life-long diseases need life-long treatment: long-term safety of ciclosporin in canine atopic dermatitis

Nuttall, Tim; Reece, Douglas; Roberts, Elizabeth

2014-01-01

Ciclosporin (Atopica; Novartis Animal Health) has been licensed for canine atopic dermatitis (AD) since 2002. Adverse events (AEs) have been reported in 55 per cent of 759 dogs in 15 clinical trials, but are rare in pharmacovigilance data (71.81 AEs/million capsules sold). Gastrointestinal reactions were most common, but were mild and rarely required intervention. Other AEs were rare (≤1 per cent in clinical trials; metabolism is not clinically significant for normal dogs. Concomitant treatment with most drugs is safe. Effects on cytochrome P450 and MDR1 P-glycoprotein activity may elevate plasma ciclosporin concentrations, but short-term changes are not clinically significant. Monitoring of complete blood counts, urinalysis or ciclosporin levels is not justified except with higher than recommended doses and/or long-term concurrent immunosuppressive drugs. Ciclosporin is not a contraindication for killed (including rabies) vaccines, but the licensed recommendation is that live vaccination is avoided during treatment. In conclusion, ciclosporin has a positive risk-benefit profile for the long-term management of canine AD. PMID:24682696

To evaluate the long-term effects of the standard (Class II) Balters bionator in growing patients with Class II malocclusion with mandibular retrusion by using morphometrics (thin-plate spline [TPS] analysis). Twenty-three Class II patients (8 male, 15 female) were treated consecutively with the Balters bionator (bionator group). The sample was evaluated at T0, start of treatment; T1, end of bionator therapy; and T2, long-term observation (including fixed appliances). Mean age at the start of treatment was 10 years 2 months (T0); at posttreatment, 12 years 3 months (T1); and at long-term follow-up, 18 years 2 months (T2). The control group consisted of 22 subjects (11 male, 11 female) with untreated Class II malocclusion. Lateral cephalograms were analyzed at the three time points for all groups. TPS analysis evaluated statistical differences (permutation tests) in the craniofacial shape and size between the bionator and control groups. TPS analysis showed that treatment with the bionator is able to produce favorable mandibular shape changes (forward and downward displacement) that contribute significantly to the correction of the Class II dentoskeletal imbalance. These results are maintained at a long-term observation after completion of growth. The control group showed no statistically significant differences in the correction of Class II malocclusion. This study suggests that bionator treatment of Class II malocclusion produces favorable results over the long term with a combination of skeletal and dentoalveolar shape changes.

Sulcus vocalis and vocal fold scar involve derangement of the superficial lamina propria of the vocal fold, which results in significant dysphonia. Many options exist for treatment, most of which have unsatisfactory and unpredictable outcomes. Autologous transplantation of temporalis fascia into the vocal fold (ATFV) has the potential to be a better treatment option, but long-term outcomes have not been well studied. Retrospective chart review and patient survey. Twenty-one patients diagnosed with vocal fold scar or sulcus vocalis and treated with ATFV with at least 1-year follow-up were included. Voice Handicap Index 10 (VHI-10) questionnaires were collected preoperatively and 6 months postoperatively. Patients were reached at the time of the study to complete another VHI-10 and a Likert scale survey. The mean decrease in VHI-10 scores between preoperation and 6 months postoperation was 8.35 ( P vocal fold for the treatment of vocal fold scar and sulcus vocalis is a safe surgery with good long-term outcomes and high patient satisfaction.

2003-01-01

Spent fuel management is perceived as one of the crucial issues to be resolved for sustainable utilisation of nuclear power. In the last decades, spent fuel management policies have shown diverging tendencies among the nuclear power production countries - a group has adhered to reprocessing- recycle and another has turned to direct disposal, while the rest of the countries have not taken decision yet, often with ''wait and see'' position. Both the closed and open fuel cycle options for spent fuel management have been subject to a number of debates with pros and cons on various issues such as proliferation risk, environmental impact, etc. The anticipation for better technical solutions that would mitigate those issues has given rise to the renewal of interest in partitioning and transmutation of harmful nuclides to be disposed of, and in a broader context, the recent initiatives for development of innovative nuclear systems. The current trend toward globalization of market economy, which has already brought important impacts on nuclear industry, might have a stimulating effect on regional-international co-operations for cost-effective efforts to mitigate some of those long-term issues associated with spent fuel management.

The purpose of this study was to evaluate the mid- and long-term results of percutaneous transhepatic cholangiography (PTC) and biliary drainage in children with isolated bilioenteric anastomotic stenosis (BAS) after pediatric liver transplantation. Sixty-four children underwent PTC from March 1993 to May 2008. Nineteen cholangiograms were normal; 10 showed intrahepatic biliary stenosis and BAS, and 35 showed isolated BAS. Cadaveric grafts were used in 19 and living donor grafts in 16 patients. Four patients received a whole liver, and 31 patients received a left lobe or left lateral segment. Roux-en-Y hepaticojejunostomy was performed in all patients. Indication for PTC was based on clinical, laboratory, and histopathologic findings. In patients with isolated BAS, dilation and biliary catheter placement, with changes every 2 months, were performed. Patients were separated into 4 groups according to number of treatment sessions required. The drainage catheter was removed if cholangiogram showed no significant residual stenosis and normal biliary emptying time after a minimum of 6 months. The relationship between risk factors (recipient's weight 20 months, 4 patients (4 of 35; 11.4%) required 1 additional treatment session (group III), and 1 patient (1 of 35; 2.9%) had a catheter placed at the end of the study period (group IV). Drainage time in group I was significantly shorter than those in groups II, III, and IV (p 0.05). The majority of complications, such as catheter displacement and leakage, were classified as minor; however, 2 patients (5.7%) with hemobilia were noted. Complications increased according to the need for reintervention. In conclusion, balloon dilation and percutaneous drainage placement is safe and effective, and it has long-term patency for children with BAS after liver transplantation. Because of prolonged treatment time, reintervention may be necessary, thereby increasing the complication rate. Balloon dilation and percutaneous drainage

Current management of glaucoma entails the medical, laser, or surgical reduction of intraocular pressure (IOP) to a predetermined level of target IOP, which is commensurate with either stability or delayed progression of visual loss. In the published literature, the hypothesis is often made that IOP control implies a single IOP measurement over time. Although the follow-up of glaucoma patients with single IOP measurements is quick and convenient, such measurements often do not adequately reflect the untreated IOP characteristics, or indeed the quality of treated IOP control during the 24-h cycle. Since glaucoma is a 24-h disease and the damaging effect of elevated IOP is continuous, it is logical that we should aim to understand the efficacy of all treatment options throughout the 24-h period. This article first reviews the concept and value of diurnal and 24-h IOP monitoring. It then critically evaluates selected available evidence on the 24-h efficacy of medical, laser and surgical therapy options. During the past decade several controlled trials have significantly enhanced our understanding on the 24-h efficacy of all glaucoma therapy options. Nevertheless, more long-term evidence is needed to better evaluate the 24-h efficacy of glaucoma therapy and the precise impact of IOP characteristics on glaucomatous progression and visual prognosis.

Long-term experience of plasmapheresis in antibody-mediated rejection in renal transplantation.

Brown, C M

2009-11-01

Antibody-mediated rejection (AMR) continues to pose a serious challenge in renal transplantation with potentially devastating consequences. Treatment options for this condition include plasmapheresis, high-dose intravenous immunoglobulin (IVIG), plasmapheresis with low-dose IVIG, and the use of rituximab (anti-CD20 chimeric antibody). We previously reported on the short-term outcome of plasmapheresis as a rescue therapy for AMR in our centre. We now report on the long-term follow up.

Effective Treatment of Intestinal Behçet's Disease with Long-Term, Low-Dose Clarithromycin

Full Text Available A 51-year-old man was referred for body weight loss and lower right abdominal pain. Total colonoscopy revealed discrete and round ulceration at the ileocecal valve, and he was diagnosed with intestinal Behçet's disease (BD. By treatment with glucocorticoid, colchicine and salazosulfapyridine, the symptoms and ulceration were improved, but cessation of glucocorticoid resulted in relapse of ulceration at the terminal ileum. Long-term, low-dose treatment with clarithromycin (CAM was implemented for chronic respiratory infections. Furthermore, we expected that this CAM treatment would also be effective in BD. During this long-term, low-dose treatment with CAM, discrete ulceration at the terminal ileum was never revealed by follow-up total colonoscopy once or twice per year for 7 years. No reports have described the effectiveness of this treatment in patients with intestinal BD; however, we confirm that long-term treatment with low-dose CAM might have clinical benefits for patients with intestinal BD.

Long-term benzodiazepine (BDZ) use and dependence affect cognitive functioning adversely and partly irreversibly. Emerging evidence suggests that pregabalin (PGB) might be a safe and efficacious treatment of long-term BDZ use. The aim of the present study was to investigate the changes in several core cognitive functions after successful treatment of long-term BDZ use and dependence with PGB. Fourteen patients with long-term BDZ use (mean duration >15 years) underwent neuropsychological assessment with the mini-mental state examination and four tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB) battery before the initiation of PGB treatment and at a two months follow-up after the cessation of BDZs. Patients' CANTAB percentile score distributions were compared with normative CANTAB data. Patients improved on cognitive measures of global cognitive functioning, time orientation, psychomotor speed, and visuospatial memory and learning with strong effect sizes. By contrast, they failed to improve on measures of attentional flexibility. Despite their significant improvement, patients' scores on most tests remained still at the lower percentiles of CANTAB normative scores. Although preliminary, our findings suggest that successful treatment of long-term BDZ use with PGB is associated with a substantial, though only partial, recovery of BDZ-compromised neuropsychological functioning, at least at a 2-month follow-up.

2017-11-01

Four "third-generation" antiepileptic drugs (AEDs) were approved for adjunctive treatment of refractory focal onset seizures during the past 10 years. Long-term efficacy and safety of the drugs were demonstrated in large extension studies and in reports of subgroups of patients not studied in pivotal trials. Reviewing extension study and post-marketing outcome series for the four newer AEDs-lacosamide, perampanel, eslicarbazepine acetate and brivaracetam-can guide clinicians in treating and monitoring patients. AED extension studies evaluate treatment retention, drug tolerability, and drug safety during individualized treatment with flexible dosing and thus provide information not available in rigid pivotal trials. Patient retention in the studies ranged from 75 to 80% at 1 year and from 36 to 68% at 2-year treatment intervals. Safety findings were generally similar to those of pivotal trials, with no major safety risks identified and with several specific adverse drug effects, such as hyponatremia, reported. The third-generation AEDs, some through new mechanisms and others with improved tolerability compared to related AEDs, provide new options in efficacy and tolerability.

To evaluate the long-term success rate of direct vision internal urethrotomy as a treatment for anterior urethral strictures. We retrospectively analyzed the results for patients who underwent internal urethrotomy from January 2009 to January 2014 for anterior urethral strictures. Patients were followed till January 2016. Patients with complicated urethral strictures with a history of previous urethroplasty, hypospadias repair, or previous radiation were excluded from the study, as anticipated low success rate of direct visual internal urethrotomy (DVIU) in these patients. The Kaplan-Meier method was used to analyze stricture-free probability after the first, second, and third urethrotomy. A total of 186 patients were included in this study. Stricture-free rates after first, second, and third urethrotomy were 29.66%, 22.64%, and 13.33%, respectively. Although DVIU may be a management option for anterior urethral stricture disease, it seems that long-term results are disappointing.

This report presents the results of a workshop intending to anticipate the long term challenges, to guide better the short term power options, to understand the available political, economical and technical assumptions for the prospective world situation, to give some strategic hints on the necessary transition. Indeed, the difficult issue which the workshop tried to tackle was how should we prepare to reveal the energetic challenge of the development of the eight to ten billion inhabitants of our Planet in the next century without jeopardizing its existence. The energetic problems, a hardcore of the international preoccupation of both growth and environment, as it was recently evidenced by the climatic conference in Kyoto, have ever been the object of a particular attention on the part of General Commissariat of Plan. Thus, the commission 'Energy in 2010 - 2020' has been instituted in April 1996 in order to update the works done in 1990 - 1991 by the commission 'Energy 2010'. Soon it occurred to this new commission the task of illuminating its works by a long term (2050 - 2100) world prospective analysis of the challenges and problems linked to energy, growth and environment. In conclusion, this document tried to find answers to questions like: - which are the risks the energy consumption augmentation entail? - can we control them by appropriate urbanism and transport policies or technological innovation?. Four options for immediate action are suggested: - the energy efficiency should become a priority objective of policies; -coping with the long term challenges requires acting at present; - building the transition between governmental leadership and market; - taking profit of all the possible synergies between short and long term planning.

Complete Treatment Versus Residual Lesion - Long-Term Evolution After Acute Coronary Syndrome

Directory of Open Access Journals (Sweden)

Alexandre de Matos Soeiro

Full Text Available Abstract Introduction: A recently published study raised doubts about the need for percutaneous treatment of nonculprit lesions in patients with acute coronary syndromes (ACS. Methods: Retrospective, unicentric, observational study. Objective: To analyze the long-term outcomes in patients undergoing treatment of the culprit artery, comparing those who remained with significant residual lesions in nonculprit arteries (group I versus those without residual lesions in other coronary artery beds (group II. The study included 580 patients (284 in group I and 296 in group II between May 2010 and May 2013. We obtained demographic and clinical data, as well as information regarding the coronary treatment administered to the patients. In the statistical analysis, the primary outcome included combined events (reinfarction/angina, death, heart failure, and need for reintervention. The comparison between groups was performed using the chi-square test and ANOVA. The long-term analysis was conducted with the Kaplan-Meier method, with a mean follow-up of 9.86 months. Results: The mean ages were 63 years in group I and 62 years in group II. On long-term follow-up, there was no significant difference in combined events in groups I and II (31.9% versus 35.6%, respectively, p = 0.76. Conclusion: The strategy of treating the culprit artery alone seems safe. In this study, no long-term differences in combined endpoints were observed between patients who remained with significant lesions compared with those without other obstructions.

The Supply of Medical Radioisotopes. Policy Options for Ensuring Long-term Supply Security of Molybdenum-99 and/or Technetium-99m Produced Without Highly Enriched Uranium Targets

International Nuclear Information System (INIS)

Westmacott, Chad; Cameron, Ron

2012-01-01

Following the shortages of the key medical radioisotopes, molybdenum-99 ( 99 Mo) and its daughter technetium-99m (' 99m Tc), the OECD-Nuclear Energy Agency (NEA) created the High-level Group on the Security of Supply of Medical Radioisotopes (HLG-MR). Since 2009, this group has identified the reasons for the isotope shortages and developed a policy approach to address the challenges to a long-term secure supply of these important medical isotopes. On top of the ongoing concerns related to long-term reliability, all current long-term major 99 Mo-producing nations have agreed to convert to using low-enriched uranium (LEU) targets for the production of 99 Mo. This decision was made based on important nonproliferation reasons; however, the conversion will have potential impacts on the global supply chain - both in terms of costs and available capacity. Recognising that conversion is important and will occur, and also recognising the need to ensure a long-term secure supply of 99 Mo/' 99m Tc, the NEA, along with stakeholders, examined potential policy options that could be used by to ensure a reliable supply of 99 Mo and/or ' 99m Tc produced without highly enriched uranium (HEU), consistent with the time frames and policies of the HLG-MR. This discussion paper provides the various policy options available to governments to encourage a reliable supply of 99 Mo and/or ' 99m Tc produced without HEU. The examination of these options was done through the lens of ensuring a reliable supply, consistent with the time frames and policies of the HLG-MR. The options described in this document are meant to meet this objective by taking one of three general actions: - Making the option of purchasing or producing non-HEU-based 99 Mo and/or ' 99m Tc more attractive. - Making the option of purchasing or producing HEU-based 99 Mo and/or ' 99m Tc less attractive. - Limiting access to HEU-based 99 Mo and/or ' 99m Tc. This paper presents the options in each category and provides some views

Perspective on long-range nuclear energy options

The study group whose effort is presented here concluded that the United States urgently needs to have a breeder option available for possible deployment before the year 2000 primarily because of uncertainties in the availability of fossil fuels and uranium supplies. It was recommended that the U/Pu LMFBR program proceed as planned, including prompt construction of the CRBRP and its associated fuel cycle facilities. Alternative cycle studies should be pursued, but without significantly delaying the current program. There are technological choices which, in suitable political contexts, may somewhat reduce proliferation risks; of these, only those that employ breeders preserve the breeder option (and the nuclear option in the long term. These alternatives must be coupled with political agreements to have any significant effect on proliferation potential internationally. These same political agreements should suffice to control the U/Pu breeder cycle; there is only a difference in degree between the U/Pu and the denatured Th/U-233 cycles

Full Text Available Abstract Background In childhood, attention deficit/hyperactivity disorder (ADHD is characterized by age-inappropriate levels of inattentiveness/disorganization, hyperactivity/impulsiveness, or a combination thereof. Although the criteria for ADHD are well defined, the long-term consequences in adults and children need to be more comprehensively understood and quantified. We conducted a systematic review evaluating the long-term outcomes (defined as 2 years or more of ADHD with the goal of identifying long-term outcomes and the impact that any treatment (pharmacological, non-pharmacological, or multimodal has on ADHD long-term outcomes. Methods Studies were identified using predefined search criteria and 12 databases. Studies included were peer-reviewed, primary studies of ADHD long-term outcomes published between January 1980 to December 2010. Inclusion was agreed on by two independent researchers on review of abstracts or full text. Published statistical comparison of outcome results were summarized as poorer than, similar to, or improved versus comparators, and quantified as percentage comparisons of these categories. Results Outcomes from 351 studies were grouped into 9 major categories: academic, antisocial behavior, driving, non-medicinal drug use/addictive behavior, obesity, occupation, services use, self-esteem, and social function outcomes. The following broad trends emerged: (1 without treatment, people with ADHD had poorer long-term outcomes in all categories compared with people without ADHD, and (2 treatment for ADHD improved long-term outcomes compared with untreated ADHD, although not usually to normal levels. Only English-language papers were searched and databases may have omitted relevant studies. Conclusions This systematic review provides a synthesis of studies of ADHD long-term outcomes. Current treatments may reduce the negative impact that untreated ADHD has on life functioning, but does not usually 'normalize' the

Disposition of already separated plutonium in Russia: Consideration of short- and long-term options

International Nuclear Information System (INIS)

Diakov, A.S.

1995-01-01

The plutonium stockpile presents a serious risk to national and international security. However, the utilization of already separated plutonium involves a complex set of political, technical, economical, and environmental problems. How Russia can best deal with all the problems associated with plutonium stockpiles is the subject of this paper. The official Russian concept of plutonium utilization views it as a valuable energy source. This concept entails the following two measures: (1) storage of both surplus weapons and civil plutonium; (2) fabrication of MOX fuel for future use in a different type of reactor: light-water reactors and fast-neutron reactors. To implement this concept, building four 800-Megawatt fast-neutron reactors and completing the construction of MOX plant is proposed. Technical and economical evaluations are being conducted on plutonium utilization in VVER-1000 reactors. When operating, these reactors (four BN-800 and seven VVER-1000) could dispose of about 9 tons of plutonium per year. But given Russia's current chaotic political and economic conditions, it seems unlikely that these plans will be carried out any time soon. Furthermore, the comparative economic analysis conducted for the different types of fuel cycles shows that due to several factors there is no economic motivation for Russia to use plutonium for fuel fabrication in the near future. These observations indicate that the real question that needs to be answered is what priority needs to be placed on short-, medium-, and long-term to identify and choose between different disposition options? This question is easily answered when one considers the currently turbulent political and economic situation in Russia. The priority that makes the most sense is to concentrate efforts on short-term options

Long-term outcome of prenatal dexamethasone treatment of 21-hydroxylase deficiency.

Lajic, Svetlana; Nordenström, Anna; Hirvikoski, Tatja

Prenatal treatment of congenital adrenal hyperplasia (CAH) with dexamethasone (DEX) has been in use since the mid- 1980s. Its effectiveness for reducing virilization of external genitalia is well established. DEX treatment has to be started in the 6th-7th postmenstrual week and continued until the results of the prenatal diagnosis are available. Hence, the dilemma is that 7 out of 8 fetuses (boys and unaffected girls) are treated unnecessarily. Girls with CAH are treated until term. Accumulating evidence from animal studies and follow-up data has raised concerns regarding the long-term consequences of this controversial treatment. We have previously reported that direct neuropsychological assessment of children exposed to DEX and controls show normal full-scale IQ, learning and longterm memory. However, the children exposed to DEX during the first trimester had an impaired verbal working memory which was significantly associated with low self-perceived scholastic competence. In addition, the children showed increased self-rated social anxiety. The same cohort of children answered questions concerning friends, activities and gender-related behaviors. The results indicate less masculine and more neutral behavior in short-term DEX-exposed boys. These findings indicate that long-term follow-ups of this group of patients are of extreme importance and that future DEX treatment of CAH may be questioned. We therefore encourage additional studies on larger cohorts in order to draw more decisive conclusions about the safety of the treatment. Until then, it is important that the parents are thoroughly informed about the potential risks and uncertainties, as well as the benefits, of this treatment. Copyright © 2011 S. Karger AG, Basel.

Biologically-equivalent dose and long-term survival time in radiation treatments

International Nuclear Information System (INIS)

Zaider, Marco; Hanin, Leonid

2007-01-01

Within the linear-quadratic model the biologically-effective dose (BED)-taken to represent treatments with an equal tumor control probability (TCP)-is commonly (and plausibly) calculated according to BED(D) = -log[S(D)]/α. We ask whether in the presence of cellular proliferation this claim is justified and examine, as a related question, the extent to which BED approximates an isoeffective dose (IED) defined, more sensibly, in terms of an equal long-term survival probability, rather than TCP. We derive, under the assumption that cellular birth and death rates are time homogeneous, exact equations for the isoeffective dose, IED. As well, we give a rigorous definition of effective long-term survival time, T eff . By using several sets of radiobiological parameters, we illustrate potential differences between BED and IED on the one hand and, on the other, between T eff calculated as suggested here or by an earlier recipe. In summary: (a) the equations currently in use for calculating the effective treatment time may underestimate the isoeffective dose and should be avoided. The same is the case for the tumor control probability (TCP), only more so; (b) for permanent implants BED may be a poor substitute for IED; (c) for a fractionated treatment schedule, interpreting the observed probability of cure in terms of a TCP formalism that refers to the end of the treatment (rather than T eff ) may result in a miscalculation (underestimation) of the initial number of clonogens

Fertility treatment: long-term growth and mental development of the children.

Science.gov (United States)

Bay, Bjørn

2014-10-01

Fertility treatment has been associated with obstetrical and perinatal complications. It is, however, uncertain whether fertility treatment or parental subfertility is associated with long-term development of the children. We aimed to assess the growth and mental health of children and adolescents conceived after fertility treatment compared to spontaneously conceived controls. First, we evaluated all previous studies comparing neurodevelopmental outcomes between children conceived after fertility treatment and spontaneous conceived controls. The systematic review clarified methodological limitations in the existing literature on the long-term development of children conceived after medical assisted reproduction. Although several studies had been published, large, well-controlled studies with long-term follow-up and thorough statistical adjustments were still few. Second, we evaluated the children's mental health by assessing the risk of mental disorders. We studied a population of 555,828 children conceived after spontaneous conception and 33,139 children conceived after fertility treatment with follow-up in 2012 when the children were 8-17 years old. The absolute risk and hazard ratio of overall and specific mental disorders were estimated while adjusting for potential confounding variables. Further, we estimated the association between subtypes of procedures, hormonal treatment, gamete types and cause of infertility on the one hand and the risk of mental disorders on the other. Children conceived after ovulation induction had a low, but significantly increased risks of autism spectrum disorders, hyperkinetic disorders, conduct, emotional, or social disorders, and tic disorders. Children conceived after IVF or ICSI showed no increased risk, except for a small risk of tic disorders. There was no risk systematically related to any specific type of hormone drug treatment. Thus, the increased risks may rely on residual confounding such as unknown parental factors

Long-term treatments with dopaminergic agents are associated with adverse effects, including augmentation. Augmentation consists of an exacerbation of restless legs syndrome (a sleep-related movement disorder) symptoms during treatment compared to those experienced during the period before therapy was initiated. The objective of this study was to examine locomotor activity in rats after long-term dopaminergic treatment and its relationship with expression of the D2 receptor, in addition to demonstrating possible evidence of augmentation. The rats were divided into control (CTRL) and drug (Pramipexole-PPX) groups that received daily saline vehicle and PPX treatments, respectively, for 71 days. The locomotor behavior of the animals was evaluated weekly in the Open Field test for 71 days. The expression of the dopamine D2 receptor was evaluated by Western Blot analysis. The animals that received the PPX demonstrated a significant reduction in locomotor activity from day 1 to day 57 and a significant increase in immobility time from day 1 to day 64 relative to baseline values, but these values had returned to baseline levels at 71 days. No changes in the expression of the D2 receptor were demonstrated after treatment with a dopaminergic agonist. This study suggests changes in locomotor activity in rats after long-term PPX treatment that include an immediate reduction of locomotion and an increase in immobilization, and after 64 days, these values returned to baseline levels without evidence of augmentation. In addition, it was not possible to demonstrate a relationship between locomotor activity and the expression of D2 receptors under these conditions.

The synthetic retinoids, the vitamin-A-derivatives ethretinate and isotretinoin, have substantially enlarged the therapeutic arsenal in dermatology. They are primarily used in severe cases of acne and cornification disorders. In the majority of cases, long-term treatment is necessary. Certain side effects in the skeletal system can occur, e.g., osteoporosis, premature epiphyseal closure, and changes similar to DISH (diffuse idiopathic skeletal hyperostosis). We discuss the reports in the literature and our own observations in 31 patients treated at the Westphalian Wilhelms University in Muenster, as well as at the Technical University in Munich. In 3 out of 31 patients treated by retinoids on a long-term basis, skeletal changes were found radiologically as a result of the retinoid medication.

FMS leads to high disability levels, poor quality of life, and extensive use of medical care. Effective pharmacological treatment options are rare, and treatment effects are often of limited duration. Duloxetine is a new selective serotonin and norepinephrine reuptake inhibitor that is licensed for the treatment of pain in diabetic neuropathy. So far two randomized, placebo-controlled trials have investigated the short-term safety and efficacy of duloxetine 60 mg/day and 120 mg/day in patients suffering from FMS over a period of 12 weeks. Both dosages were superior to placebo in pain relief, and improvement in quality of life and depressive symptoms. The analgesic effect was largely independent of the antidepressant action of duloxetine. The higher dose of 120 mg/day further reduced the tender point count and elevated the tender point pain thresholds. Only mild to moderate adverse effects were reported. Duloxetine 60 mg/day and 120 mg/day has proven to be beneficial in the treatment of FMS symptoms. As true for other antidepressants further studies are needed to assess the long-term efficacy and safety of duloxetine as an additional pharmacological treatment option in FMS.Keywords: fibromyalgia syndrome, duloxetine, antidepressant, review, SNRI

The WISMUT remediation project in the States of Saxony and Thuringia, Germany, comprises several mine and mill sites including large volumes of production residues. Due to the climate, the intensive land use and the regulatory conditions, the water path is most important in evaluating remediation options. Water treatment is an integral part of mine flooding, mine dump and tailings remediation, and treatment costs represent a major portion of the overall costs of the project. Uncertainties in the estimations of quantities of mine and seepage waters, variations in quality from site to site, and changing conditions in time demand a strategic approach to the selection and optimization of water treatment methods. The paper describes options considered and experience gained including efforts to limit long-term treatment costs by developing and applying passive treatment systems and negotiating acceptable discharge limits.

Full Text Available Yigit Akin,1 Selcuk Yucel21Department of Urology, Harran University School of Medicine, Sanliurfa, Turkey; 2Department of Urology, Acibadem University School of Medicine, Istanbul, TurkeyIntroduction: Extracorporeal shock wave lithotripsy (ESWL is a well-known and successful treatment modality. In addition, it can be used in premature infants. ESWL is used to treat kidney and ureter stones in children. However, although it is a preferred noninvasive treatment in that setting, there is debate about its long-term effects on growing kidneys in children.Objectives: To investigate the long-term effects of pediatric ESWL on renal function in light of updated literature.Methods: PubMed and Medline were searched for studies on ESWL in a pediatric population with keywords including efficacy, child, kidney calculi, ureter calculi, lithotripsy, injury, vascular trauma, and shock waves. The research was limited to the English literature during a period from 1980 to 2014. In total, 3,000 articles were evaluated, but only 151 papers were considered. Only the manuscripts directly related to the reviewed subjects were included in the current study.Results: However, the acute effects of ESWL in kidney are well-described. Although there are limited studies on the long-term effects of ESWL in children, there is a widespread opinion that ESWL is not affecting renal functions in the long-term.Conclusion: ESWL is a safe, effective, and noninvasive treatment option in children. Although ESWL can cause some acute effects in the kidney, there is no long-term effect on the growing kidneys of children.Keywords: child, lithotripsy, nephrolithiasis, renal injury, vascular trauma

Full Text Available Immune checkpoint inhibitors have drastically changed in the treatment of many kinds of malignancies, especially malignant melanoma. The focus of the recent experiments has not only been on their efficacy but also immune-related adverse events (irAEs. We report a case of fulminant hepatitis due to nivolumab. In this case, the patient had undergone long-term nivolumab therapy. He did not complain of any symptoms but his liver enzyme levels were extremely elevated (grade 4. We promptly decided to start oral corticosteroids in the patient. His liver function rapidly improved. The dose of corticosteroids was gradually reduced. Our case demonstrates that sudden onset fulminant hepatitis can occur despite the safe use of long-term nivolumab therapy. The irAE can improve rapidly with proper corticosteroid treatment. This report will be useful for the physicians who always use immune checkpoint inhibitors.

Models incorporating long-term outcomes (LTOs) are not available to assess the health economic impact of attention-deficit/hyperactivity disorder (ADHD). Develop a conceptual modelling framework capable of assessing long-term economic impact of ADHD therapies. Literature was reviewed; a conceptual structure for the long-term model was outlined with attention to disease characteristics and potential impact of treatment strategies. The proposed model has four layers: i) multi-state short-term framework to differentiate between ADHD treatments; ii) multiple states being merged into three core health states associated with LTOs; iii) series of sub-models in which particular LTOs are depicted; iv) outcomes collected to be either used directly for economic analyses or translated into other relevant measures. This conceptual model provides a framework to assess relationships between short- and long-term outcomes of the disease and its treatment, and to estimate the economic impact of ADHD treatments throughout the course of the disease.

A total of 211 patients with limited small cell lung cancer were assessed retrospectively for long-term toxicities, treatment-related deaths, and second primaries. All had received treatment with various combinations of doxorubicin, vincristine, cisplatin, lomustine, cyclophosphamide, and etoposide with or without split-course thoracic radiotherapy (4,000 cGy/10 fractions) and/or split-course prophylactic cranial irradiation (3,600 cGy/10 fractions). Sixty-eight (32%) of the patients survived longer than 1.5 years and formed the basis of this study. Debilitating pulmonary, cardiac, and neurologic toxicity was noted in 12%, 14%, and 15%, respectively, of long-term survivors. These complications were the result of aggressive combined modality therapy. Certain drugs appeared to cause additive toxicity when combined with radiation. Three patients developed new primary tumors of squamous cell origin. Attention must be directed to defining the safest way to employ aggressive combined modality treatment for these patients

A comparative review of the options for treatment of erectile dysfunction: which treatment for which patient?

Hatzimouratidis, Konstantinos; Hatzichristou, Dimitrios G

2005-01-01

The field of erectile dysfunction (ED) has been revolutionised over the last two decades. Several treatment options are available today, most of which are associated with high efficacy rates and favourable safety profiles. A MEDLINE search was undertaken in order to evaluate all currently available data on treatment modalities for ED. Phosphodiesterase type 5 (PDE5) inhibitors (sildenafil, tadalafil, vardenafil) are currently the first-choice of most physicians and patients for the treatment of ED. PDE5 inhibitors have differences in their pharmacological profiles, the most obvious being the long duration of action of tadalafil, but there are no data supporting superiority for any one of them in terms of efficacy or safety. Sublingual apomorphine has limited efficacy compared with the PDE5 inhibitors, and its use is limited to patients with mild ED. Treatment failures with oral drugs may be due to medication, clinician and patient issues. The physician needs to address all of these issues in order to identify true treatment failures. Patients who are truly unresponsive to oral drugs may be offered other treatment options.Intracavernous injections of alprostadil alone, or in combination with other vasoactive agents (papaverine and phentolamine), remain an excellent treatment option, with proven efficacy and safety over time. Topical pharmacotherapy is appealing in nature, but currently available formulations have limited efficacy. Vacuum constriction devices may be offered mainly to elderly patients with occasional intercourse attempts, as younger patients show limited preference because of the unnatural erection that is associated with this treatment modality. Penile prostheses are generally the last treatment option offered, because of invasiveness, cost and non-reversibility; however, they are associated with high satisfaction rates in properly selected patients. All treatment options are associated with particular strengths and weaknesses. A patient

To study the efficacy of long-term treatment with norethindrone acetate (NETA) in patients with rectovaginal endometriosis. This retrospective cohort study included 103 women with pain symptoms caused by rectovaginal endometriosis. Patients received NETA alone (2.5mg/day up to 5mg/day) for 5 years. Primary outcome was the degree of satisfaction with treatment after 5 years of progestin therapy. Secondary outcomes were the assessment of any variation in pain symptoms and the volumetric assessment of the disease by magnetic resonance imaging (MRI). Sixty-one women completed the 5-year follow-up (61/103, 59.2%) with 16 women withdrawing because of adverse effects (38.1%). Overall, 68.8% (42/61) of the women who completed the study were satisfied or very satisfied of this long term NETA treatment. This represents a 40.8% (42/103) of the patients enrolled. Intensity of chronic pelvic pain and deep dyspareunia significantly decreased during treatment (pendometriosis under NETA treatment. Five-year therapy with NETA is safe and well tolerated by women with rectovaginal endometriosis. Due to its low cost and good pharmacological profile, it represents a good candidate for long-term treatment in this setting. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available Retrospective analysis was performed on 30 patients of skull defect who underwent surgical repair. Intraoperative and postoperative curative effect was evaluated on those patients, and the results showed that the incidence rate of intraoperative dura mater defect (P = 0.001, early postoperative complications [new epilepsy (P = 0.035 and effusion (P = 0.021] and late postoperative complications [foreign body sensation (P = 0.035 and dizziness and headache (P = 0.050] in long-term skull defect group were all higher than those in control group. In conclusion, surgical repair of long-term skull defect incurring high risk and various complications will not be an ideal management. Therefore, early surgical treatment for skull defect is suggested. DOI: 10.3969/j.issn.1672-6731.2015.12.016

Long-term care in Israel: challenges and reform options.

This paper has two objectives. The first is to examine the Israeli long-term care (LTC) system that is marked by rapidly increasing demands, and a multitude of public and private LTC arrangements. The second is to propose a reform to improve the system's efficiency and equity. The paper studies the LTC services in Israel, and the private-public composition in funding, fund holding, and provision of LTC. It focuses on structural deficiencies in the organization of each of these functions separately, and in combination. In many countries LTC has evolved in a patchwork fashion that at some point in time needs rethinking and rationalization. Israel is a case in point. In spite of numerous LTC arrangements supported by the state, in the absence of a comprehensive strategy, these have not generated a coherent system that can deal efficiently and equitably with existing and fast growing LTC needs, on the one hand, and the resources available to it, on the other. The current system is fragmented. It provides limited coverage and insufficient benefits in a troublesome fashion to public. The findings suggest that Israel can achieve at least in the short term, universal entitlement to LTC at lower financial and social cost, than the current costs of the system. In the medium and long term, the country will need to consider the trade between the burden of direct care on households or the tax burden of publicly supported and organized care. To remedy the situation the paper suggests a two-planked reform. The first is integration of the current fragmented publicly supported system while deciding on LTC either as a "social endeavor" under a separate authority responsible for implementing the public LTC budget, or as a "medical endeavor", putting this responsibility under the Israeli sickness funds. The second plank, building on the first, comprises extension of universal entitlement to LTC. Such an extension would increase public spending in the long term; simultaneously, it

The aim of this study was to assess the long term results of treatment and rehabilitation of childhood dysphonia. This study included a group of adolescents (n=29) aged from 15 to 20 who were treated due to pediatric hyperfunctional dysphonia and soft vocal fold nodules during their pre-mutational period (i.e. between 5 and 12 years of age). The pre-mutational therapy was comprised of proper breathing pattern training, voice exercises and psychological counseling. Laryngostroboscopic examination and perceptual analysis of voice were performed in each patient before treatment and one to four years after mutation was complete. The laryngostroboscopic findings, i.e. symmetry, amplitude, mucosal wave and vocal fold closure, were graded with NAPZ scale, and the GRBAS scale was used for the perceptual voice analysis. Complete regression of the childhood dysphonia was observed in all male patients (n=14). Voice disorders regressed completely also in 8 out of 15 girls, but symptoms of dysphonia documented on perceptual scale persisted in the remaining seven patients. Complex voice therapy implemented in adolescence should be considered as either the treatment or preventive measure of persistent voice strain, especially in girls.

Full Text Available The number of long-term survivors is increasing in the western countries due to remarkable improvements in the treatment of childhood cancer. The long-term complications of childhood cancer survivors in these countries were brought to light by the childhood cancer survivor studies. In Korea, the 5-year survival rate of childhood cancer patients is approaching 70%; therefore, it is extremely important to undertake similar long-term follow-up studies and comprehensive long-term care for our population. On the basis of the experiences of childhood cancer survivorship care of the western countries and the current Korean status of childhood cancer survivors, long-term follow-up study and long-term care systems need to be established in Korea in the near future. This system might contribute to the improvement of the quality of life of childhood cancer survivors through effective intervention strategies.

To evaluate the role of treatment timing on long-term dentoskeletal effects of Class II treatment with removable functional appliances followed by full-fixed appliance therapy. A group of 46 patients (23 females and 23 males) with Class II malocclusion treated consecutively with either Bionator or Activator, followed by fixed appliances was compared with a matched control group of 31 subjects (16 females and 15 males) with untreated Class II malocclusion. The treated sample was evaluated at T1, start of treatment (mean age: 9.9 ± 1.3 years); T2, end of functional treatment and prior to fixed appliances (mean age: 11.9 ± 1.3 years); and T3, long-term observation (mean age: 18.3 ± 2.1 years). The treated and the control samples were divided into pre-pubertal and pubertal groups according to skeletal maturity observed at the start of treatment. Statistical comparisons were performed with independent sample t-tests. When treatment was initiated before puberty, Class II correction was mostly confined to the dentoalveolar changes, with significant improvements of both overjet and molar relationships. On the other hand, treatment with the outset at puberty produced significant long-term improvement of sagittal skeletal relationships, which were mainly sustained by mandibular changes. Treatment with removable functional appliances (Bionator or Activator) followed by full-fixed appliances produced significant skeletal long-term changes when it begins at puberty. Prepubertal Class II treatment results primarily in dentoalveolar changes. © The Author 2017. Published by Oxford University Press on behalf of the European Orthodontic Society. All rights reserved.

Studies investigating long-term health conditions in patients with craniopharyngioma are limited by short follow-up durations and generally do not compare long-term health effects according to initial craniopharyngioma treatment approach. In addition, studies comparing long-term health conditions between patients with childhood- and adult-onset craniopharyngioma report conflicting results. The objective of this study was to analyse a full spectrum of long-term health effects in patients with craniopharyngioma according to initial treatment approach and age group at craniopharyngioma presentation. Cross-sectional study based on retrospective data. We studied a single-centre cohort of 128 patients with craniopharyngioma treated from 1980 onwards (63 patients with childhood-onset disease). Median follow-up since craniopharyngioma presentation was 13 years (interquartile range: 5-23 years). Initial craniopharyngioma treatment approaches included gross total resection ( n  = 25), subtotal resection without radiotherapy ( n  = 44), subtotal resection with radiotherapy ( n  = 25), cyst aspiration without radiotherapy ( n  = 8), and 90 Yttrium brachytherapy ( n  = 21). Pituitary hormone deficiencies (98%), visual disturbances (75%) and obesity (56%) were the most common long-term health conditions observed. Different initial craniopharyngioma treatment approaches resulted in similar long-term health effects. Patients with childhood-onset craniopharyngioma experienced significantly more growth hormone deficiency, diabetes insipidus, panhypopituitarism, morbid obesity, epilepsy and psychiatric conditions compared with patients with adult-onset disease. Recurrence-/progression-free survival was significantly lower after initial craniopharyngioma treatment with cyst aspiration compared with other therapeutic approaches. Survival was similar between patients with childhood- and adult-onset craniopharyngioma. Long-term health conditions were comparable after

Ustekinumab as an Alternative Treatment Option for Chronic Pityriasis Rubra Pilaris

Directory of Open Access Journals (Sweden)

Mudit Chowdhary

2015-03-01

Full Text Available Pityriasis rubra pilaris (PRP is an exceptionally rare, chronic inflammatory dermatosis of unknown etiology. Patients classically present with small, follicular keratosis and salmon-colored plaques that begin at the head and neck and slowly progress to widespread erythroderma including the palms and soles. It is difficult to distinguish PRP from other inflammatory dermatoses; however, features that help aid in the diagnosis include ‘islands' of spared skin, orangish hue and typical findings on biopsy. There are no specific guidelines on therapy and treatment options include corticosteroids, vitamin D analogs, retinoids, methotrexate, cyclosporine, azathioprine and tumor necrosis factor alpha antagonists. Unfortunately options are limited for patients when these drugs do not work. We report a case of chronic PRP, refractory to conventional treatment, successfully treated with ustekinumab monotherapy. The patient was treated with 90 mg subcutaneous ustekinumab injections and began to show improvement within only 8 weeks. Long-term control of the disease has been attained without any significant side effects. We report this case to show that ustekinumab can be used as an alternative treatment method for patients with chronic, unremitting PRP. Treatment response is remarkably rapid and the infrequent dosing leads to patient compliance and a significantly improved quality of life.

Objective Despite modern anti-epileptic drug treatment, approximately 30% of epilepsies remain medically refractory and for these patients, epilepsy surgery may be a treatment option. There have been numerous studies demonstrating good outcome of epilepsy surgery in the short to median term however, there are a limited number of studies looking at the long-term outcomes. The aim of this study was to ascertain the long-term outcome of resective epilepsy surgery in a large neurosurgery hospital in the U.K. Methods This a retrospective analysis of prospectively collected data. We used the 2001 International League Against Epilepsy (ILAE) classification system to classify seizure freedom and Kaplan-Meier survival analysis to estimate the probability of seizure freedom. Results We included 284 patients who underwent epilepsy surgery (178 anterior temporal lobe resections, 37 selective amygdalohippocampectomies, 33 temporal lesionectomies, 36 extratemporal lesionectomies), and had a prospective median follow-up of 5 years (range 1–27). Kaplan-Meier estimates showed that 47% (95% CI 40–58) remained seizure free (apart from simple partial seizures) at 5 years and 38% (95% CI 31–45) at 10 years after surgery. 74% (95% CI 69–80) had a greater than 50% seizure reduction at 5 years and 70% (95% CI 64–77) at 10 years. Patients who had an amygdalohippocampectomy were more likely to have seizure recurrence than patients who had an anterior temporal lobe resection (p = 0.006) and temporal lesionectomy (p = 0.029). There was no significant difference between extra temporal and temporal lesionectomies. Hippocampal sclerosis was associated with a good outcome but declined in relative frequency over the years. Conclusion The vast majority of patients who were not seizure free experienced at least a substantial and long-lasting reduction in seizure frequency. A positive long-term outcome after epilepsy surgery is possible for many patients and especially those with

Bowel function in long-term rectal cancer survivors with anastomosis has not been characterized adequately. We hypothesized that bowel function is associated with patient, disease, and treatment characteristics. The cohort study included Kaiser Permanente members who were long-term (≥5 years) rectal cancer survivors with anastomosis. Bowel function was scored using the self-administered, 14-item Memorial Sloan-Kettering Cancer Center Bowel Function Index. Patient, cancer, and treatment variables were collected from the electronic medical chart. We used multiple regression to assess the relationship of patient- and treatment-related variables with the bowel function score. The study included 381 anastomosis patients surveyed an average 12 years after their rectal cancer surgeries. The total bowel function score averaged 53 (standard deviation, 9; range, 31-70, higher scores represent better function). Independent factors associated with worse total bowel function score included receipt of radiation therapy (yes vs. no: 5.3-unit decrement, p 6 cm: 3.2-unit decrement, p decrement, p decrement, p model explained 20% of the variation in the total bowel function score. Low tumor location, radiation therapy, temporary ostomy during initial treatment, and history of smoking were linked with decreased long-term bowel function following an anastomosis. These results should improve decision-making about surgical options.

1995-01-01

In a planning system intended to be governed primarily by policies in statutory plans a reasonable horizon for long term planning is 10 years or longer. Because of statutory requirements, developers have no option but to pay due regard to, and take a full part in, long term planning. The paper examines the type of policies which have emerged in the last few years to cater for wind energy development. It canvasses the merits of different types of policies. Finally, it discusses the policy framework which may emerge to cater for development outside NFFO. (Author)

Current and potential treatment options for hyperphosphatemia.

Carfagna, Fabio; Del Vecchio, Lucia; Pontoriero, Giuseppe; Locatelli, Francesco

2018-05-21

Hyperphosphatemia is common in late stages of chronic kidney disease and is often associated with elevated parathormone levels, abnormal bone mineralization, extra-osseous calcification, and increased risk of cardiovascular events and death. Several classes of oral phosphate binders are available to help control plasma phosphorus levels. Although effective at lowering serum phosphorus, they all have safety, tolerability, and compliance issues that need to be considered when selecting which one to use. Areas covered: This paper reviews the most established treatment options for hyperphosphatemia, in patients with chronic kidney disease, focusing on the new inhibitors of active phosphate absorption. Expert opinion: The prevention and the treatment of hyperphosphatemia is today far to be satisfactory. Nonetheless, an extending range of phosphate binders are now available. Aluminum has potentially serious toxic risks. Calcium-based binders are very effective but can lead to hypercalcemia and/or positive calcium balance and progression of cardiovascular calcification. No long-term data are available for the new calcium acetate/magnesium combination product. Lanthanum is an effective phosphate binder, and long-term effects of tissue deposition seem clinically irrelevant. Sevelamer, appear to have profiles that would lead to pleiotropic effects and reduced progression of vascular calcification, and the main adverse events seen with these agents are gastrointestinal. Iron has a powerful capability of binding phosphate, thus numerous preparations are available, both with and without significant systemic absorption of the iron component. The inhibitors of active intestinal phosphate transport, with their very selective mechanism of action and low pill burden seem the most interesting approach; however, do not seem at present to be effective alone, in reducing serum phosphorus levels.

Pelvic radiation disease: Updates on treatment options

2015-01-01

Pelvic cancers are among the most frequently diagnosed neoplasms and radiotherapy represents one of the main treatment options. The irradiation field usually encompasses healthy intestinal tissue, especially of distal large bowel, thus inducing gastrointestinal (GI) radiation-induced toxicity. Indeed, up to half of radiation-treated patients say that their quality of life is affected by GI symptoms (e.g., rectal bleeding, diarrhoea). The constellation of GI symptoms - from transient to long-term, from mild to very severe - experienced by patients who underwent radiation treatment for a pelvic tumor have been comprised in the definition of pelvic radiation disease (PRD). A correct and evidence-based therapeutic approach of patients experiencing GI radiation-induced toxicity is mandatory. Therapeutic non-surgical strategies for PRD can be summarized in two broad categories, i.e., medical and endoscopic. Of note, most of the studies have investigated the management of radiation-induced rectal bleeding. Patients with clinically significant bleeding (i.e., causing chronic anemia) should firstly be considered for medical management (i.e., sucralfate enemas, metronidazole and hyperbaric oxygen); in case of failure, endoscopic treatment should be implemented. This latter should be considered the first choice in case of acute, transfusion requiring, bleeding. More well-performed, high quality studies should be performed, especially the role of medical treatments should be better investigated as well as the comparative studies between endoscopic and hyperbaric oxygen treatments.

The Ministry of Health in Malawi is implementing a pragmatic and innovative approach for the management of all HIV-infected pregnant women, termed Option B+, which consists of providing life-long antiretroviral treatment, regardless of their CD4 count or clinical stage. Our objective was to determine if Option B+ represents a cost-effective option. A decision model simulates the disease progression of a cohort of HIV-infected pregnant women receiving prophylaxis and antiretroviral therapy, and estimates the number of paediatric infections averted and maternal life years gained over a ten-year time horizon. We assess the cost-effectiveness from the Ministry of Health perspective while taking into account the practical realities of implementing ART services in Malawi. If implemented as recommended by the World Health Organization, options A, B and B+ are equivalent in preventing new infant infections, yielding cost effectiveness ratios between US$ 37 and US$ 69 per disability adjusted life year averted in children. However, when the three options are compared to the current practice, the provision of antiretroviral therapy to all mothers (Option B+) not only prevents infant infections, but also improves the ten-year survival in mothers more than four-fold. This translates into saving more than 250,000 maternal life years, as compared to mothers receiving only Option A or B, with savings of 153,000 and 172,000 life years respectively. Option B+ also yields favourable incremental cost effectiveness ratios (ICER) of US$ 455 per life year gained over the current practice. In Malawi, Option B+ represents a favorable policy option from a cost-effectiveness perspective to prevent future infant infections, save mothers' lives and reduce orphanhood. Although Option B+ would require more financial resources initially, it would save societal resources in the long-term and represents a strategic option to simplify and integrate HIV services into maternal, newborn and child

Long-term planning models are useful to build plausible options for future energy systems and must consequently address the technological feasibility and associated cost of these options. This paper focuses on the electricity sector and on problems of flexibility and reliability in power systems in order to improve results provided by long-term planning exercises: flexibility needs are integrated as an additional criterion for new investment decisions and, reliability requirements are assessed through the level of electrical losses they induced and a related cost. These approaches are implemented in a long-term planning model and demonstrated through a study of the Reunion Island.

Antibiotic administration is the standard treatment for the bacterium Helicobacter pylori, the main causative agent of peptic ulcer disease and gastric cancer. However, the long-term consequences of this treatment on the human indigenous microbiota are relatively unexplored. Here we studied short- and long-term effects of clarithromycin and metronidazole treatment, a commonly used therapy regimen against H. pylori, on the indigenous microbiota in the throat and in the lower intestine. The bacterial compositions in samples collected over a four year period were monitored by analyzing the 16S rRNA gene using 454-based pyrosequencing and terminal-restriction fragment length polymorphism (T-RFLP). While the microbial communities of untreated control subjects were relatively stable over time, dramatic shifts were observed one week after antibiotic treatment with reduced bacterial diversity in all treated subjects in both locations. While the microbiota of the different subjects responded uniquely to the antibiotic treatment some general trends could be observed; such as a dramatic decline in Actinobacteria in both throat and feces immediately after treatment. Although the diversity of the microbiota subsequently recovered to resemble the pre treatment states, the microbiota remained perturbed in some cases for up to four years post treatment. In addition, four years after treatment high levels of the macrolide resistance gene erm(B) were found, indicating that antibiotic resistance, once selected for, can persist for longer periods of time than previously recognized. This highlights the importance of a restrictive antibiotic usage in order to prevent subsequent treatment failure and potential spread of antibiotic resistance.

Severe obesity is the only obesity classification increasing in prevalence among children and adolescents. Treatment options that produce meaningful and sustained weight loss and comorbidity resolution are urgently needed. The purpose of this review is to provide a brief overview of the current treatment options for pediatric severe obesity and offer suggestions regarding future opportunities for accelerating the development and evaluation of innovative treatment strategies. At present, there are three treatment options for youth with severe obesity: lifestyle modification therapy, pharmacotherapy, and bariatric surgery. Lifestyle modification therapy can be useful for improving many chronic disease risk factors and comorbid conditions but often fails to achieve clinically meaningful and sustainable weight loss. Pharmacotherapy holds promise as an effective adjunctive treatment but remains in the primordial stages of development in the pediatric population. Bariatric surgery provides robust weight loss and risk factor/comorbidity improvements but is accompanied by higher risks and lower uptake compared to lifestyle modification therapy and pharmacotherapy. New areas worth pursuing include combination pharmacotherapy, device therapy, identification of predictors of response aimed at precision treatment, and interventions in the postbariatric surgical setting to improve long-term outcomes. Treating pediatric severe obesity effectively and safely is extremely challenging. Some progress has been made, but substantially more effort and innovation are needed in the future to combat this serious and ongoing medical and public health issue. © 2018 The Obesity Society.

Methodological and ethical constraints have hampered studies into long-term lasting outcomes of stimulant treatment in individuals with attention-deficit/hyperactivity disorder (ADHD). Lasting effects may be beneficial (i.e. improved functioning even when treatment is temporarily ceased) or detrimental (i.e. worse functioning while off medication), but both hypotheses currently lack empirical support. Here we investigate whether stimulant treatment history predicts long-term development of ADHD symptoms, social-emotional functioning or cognition, measured after medication wash-out. ADHD symptoms, social-emotional functioning and cognitive test performance were measured twice, 6 years apart, in two ADHD groups (stimulant-treated versus not stimulant-treated between baseline and follow-up). Groups were closely matched on baseline clinical and demographic variables (n = 148, 58% male, age = 11.1). A matched healthy control group was included for reference. All but two outcome measures (emotional problems and prosocial behaviour) improved between baseline and follow-up. Improvement over time in the stimulant-treated group did not differ from improvement in the not stimulant-treated group on any outcome measure. Stimulant treatment is not associated with the long-term developmental course of ADHD symptoms, social-emotional functioning, motor control, timing or verbal working memory. Adolescence is characterised by clinical improvement regardless of stimulant treatment during that time. These findings are an important source to inform the scientific and public debate.

Myasthenia gravis is an autoimmune neuromuscular disorder. There are several treatment options, including symptomatic treatment (acetylcholinesterase inhibitors), short-term immunosuppression (corticosteroids), long-term immunosuppression (azathioprine, cyclosporine, cyclophosphamide, methotrexate, mycophenolate mofetil, rituximab, tacrolimus), rapid acting short-term immunomodulation (intravenous immunoglobulin, plasma exchange), and long-term immunomodulation (thymectomy). This review explores in detail these different treatment options. Potential future treatments are also discussed. PMID:21845054

The long-term skeletal effects of Class II treatment in growing individuals using high-pull facebow headgear and fixed edgewise appliances have not been reported. The purpose of this study was to evaluate the long-term skeletal effects of treatment using high-pull headgear followed by fixed orthodontic appliances compared to an untreated control group. Changes in anteroposterior and vertical cephalometric measurements of 42 Class II subjects (n = 21, mean age = 10.7 years) before treatment, after headgear correction to Class I molar relationship, after treatment with fixed appliances, and after long-term retention (mean 4.1 years), were compared to similar changes in a matched control group (n = 21, mean age = 10.9 years) by multivariable linear regression models. Compared to control, the study group displayed significant long-term horizontal restriction of A-point (SNA = -1.925°, P appliances resulted in correction to Class I molar through restriction of horizontal maxillary growth with continued horizontal mandibular growth and vertical skeletal changes unaffected. The anteroposterior molar correction and skeletal effects of this treatment were stable long term.

The aim of this study was to evaluate the efficacy and safety of fractional carbon dioxide laser for the treatment of acne scars. Thirty-one participants, 15 female and 16 male, whose mean age was 34.84 ± 10.94 years, were included in this prospective study. The study took place between 2012 and 2016. Participants were evaluated with the "ECCA Grading Scale" before the first session, 3 months (short-term evaluation) and 3 years after the last session (long-term evaluation). Participants received two or three treatment sessions at 4-week intervals, with a 10,600 nm fractional carbon dioxide laser with pulse energies ranging between 100 and 160 mJ, 120 spot type, 75-100 spot/cm 2 density, and 30 W power. Self-assessments by the participants were done 3 months and 3 years after the last session. The mean ECCA score was 107.90 ± 39.38 before the first session, and 82.17 ± 36.23 at the time of short-term evaluation (p = 0.000). The grade of improvement at the short-term evaluation was as follows: no improvement, mild, moderate, and significant improvement for 7 (22.6%), 11 (35.5%), 9 (29%), and 4 (12.9%) of the participants, respectively. Regarding self-assessments, 80.6 and 61.3% of the participants rated themselves as having at least mild improvement at the short-term and the long-term follow-up periods, respectively. The results of this study suggest that fractional carbon dioxide laser is an efficient treatment option for acne scars. Furthermore, self-assessment results show that more than half of the participants still experience at least mild improvement at the end of 3 years.

Understanding the extent to which current antibiotic prescribing behaviour is influenced by clinicians' historical patterns of practice will help target interventions to optimize antibiotic use in long-term care. Our objective was to evaluate whether clinicians' historical prescribing behaviours influence the start, prolongation and class selection for treatment with antibiotics in residents of long-term care facilities. We conducted a retrospective cohort study of all physicians who prescribed to residents in long-term care facilities in Ontario between Jan. 1 and Dec. 31, 2014. We examined variability in antibiotic prescribing among physicians for 3 measures: start of treatment with antibiotics, use of prolonged durations exceeding 7 days and selection of fluoroquinolones. Funnel plots with control limits were used to determine the extent of variation and characterize physicians as extreme low, low, average, high and extreme high prescribers for each tendency. Multivariable logistic regression was used to assess whether a clinician's prescribing tendency in the previous year predicted current prescribing patterns, after accounting for residents' demographics, comorbidity, functional status and indwelling devices. Among 1695 long-term care physicians, who prescribed for 93 132 residents, there was wide variability in the start of antibiotic treatment (median 45% of patients, interquartile range [IQR] 32%-55%), use of prolonged treatment durations (median 30% of antibiotic prescriptions, IQR 19%-46%) and selection of fluoroquinolones (median 27% of antibiotic prescriptions, IQR 18%-37%). Prescribing tendencies for antibiotics by physicians in 2014 correlated strongly with tendencies in the previous year. After controlling for individual resident characteristics, prior prescribing tendency was a significant predictor of current practice. Physicians prescribing antibiotics exhibited individual, measurable and historical tendencies toward start of antibiotic treatment

Calcium-alpha-ketoglutarate (Ca-ket) is known as a highly effective phosphate (P) binder in hemodialysis (HD) patients. In addition, alpha-ketoglutarate has been shown to improve metabolic alterations. We investigated the effect of long-term P-binding therapy with Ca-ket to determine whether P accumulation is the main reason of secondary hyperparathyroidism (HPT) in HD patients or not. Ca-ket was prescribed to 14 HD patients as a soluble preparation in a mean dosage of 4.5 g/day (0.975 g elemental Ca) for a period of 36 months. Serum P continuously dropped from prestudy 2.6 +/- 0.1 (mean +/- SEM) to 1.9 +/- 0.07 mmol/l (p < 0.001), whereas serum Ca increased from 2.2 +/- 0.1 to 2.47 +/- 0.08 mmol/l (p < 0.05). Thus, Ca/P ratio in serum converted significantly from 0.91 +/- 0.02 (prestudy) to 1.28 +/- 0.01 (p < 0.001). Intact parathyroid hormone (iPTH) continuously normalized in all patients from 29 +/- 5 to 8 +/- 2 pmol/l (p < 0.001). The present data show that long-term treatment with Ca-ket normalizes secondary HPT by simultaneously P binding and correcting Ca/P ratio in serum without vitamin D treatment.

Are long-term bisphosphonate users a reality?

2012-01-01

The prevalence of long-term bisphosphonate use may be low due to low refill compliance and gaps in treatment. An analysis of the prescription history of 58,674 bisphosphonate users in Denmark found that only 2.8 % had received ten dose years of treatment or above. INTRODUCTION: This study aims...... to describe the demographics of present bisphosphonate (BP) users, to determine the prevalence of long-term BP use, and to establish if long-term use (a 10-year history of osteoporosis treatment) translated to ten dose years of bisphosphonate prescriptions filled, given the propensity for treatment gaps...... more than ten dose years of a BP. For any osteoporosis drug, 3.0 % had received ten dose years or more, while 23.2 % had received between 5 and 10 years of treatment. CONCLUSION: Long-term users with ten dose years or more of a BP are rare due to periods of low compliance and gaps, with a discrepancy...

This study investigated if acute and delayed deferoxamine treatment attenuates long-term sequelae after germinal matrix hemorrhage (GMH). Bacterial collagenase (0.3 U) was infused intraparenchymally into the right hemispheric ganglionic eminence in P7 rat pups to induce GMH. GMH animals received either deferoxamine or vehicle twice a day for 7 consecutive days. Deferoxamine administration was initiated at either 1 hour or 72 hours post-GMH. Long-term neurocognitive deficits and motor coordination were assessed using Morris water maze, rotarod, and foot fault tests between day 21 to 28 post-GMH. At 28 days post-GMH, brain morphology was assessed and extracellular matrix protein (fibronectin and vitronectin) expression was determined. Acute and delayed deferoxamine treatment improved long-term motor and cognitive function at 21 to 28 days post-GMH. Attenuated neurofunction was paralleled with improved overall brain morphology at 28 days post-GMH, reducing white matter loss, basal ganglia loss, posthemorrhagic ventricular dilation, and cortical loss. GMH resulted in significantly increased expression of fibronectin and vitronectin, which was reversed by acute and delayed deferoxamine treatment. Acute and delayed deferoxamine administration ameliorated long-term sequelae after GMH. © 2014 American Heart Association, Inc.

Purpose: To identify results and prognostic factors on long-term survival and local control following treatment of localized Ewing's sarcoma. Patients and Methods: Between 1979 and 2004, a total of 60 children and young adults with Ewing's sarcoma were treated. Patients with distant metastases at presentation (n = 6) and recurrent cases (n = 2) were excluded from this analysis. Patients were exclusively treated within ongoing national and international protocols CESS-81, CESS-86, EICESS-92, EURO-EWING-99. All patients received local irradiation with a total dose of 45-60 Gy; in addition, 41 (79%) of the patients had local surgical procedures, 27 (52%) of them with clear margins. Results: Overall survival rates at 5 and 10 years were 56% and 45%, respectively. Patients ≤ 14 years at diagnosis had overall survival rates of 66% and 61% at 5 and 10 years compared to older patients with corresponding survival rates of 47% and 31%, respectively (p = 0.05). Patients with tumors of lower volume (≤ 100 ml) had significantly better survival rates at 5 and 10 years: 82% and 60% versus 42% und 39% (p = 0.03). Seven of 52 (14%) patients experienced local failure; no significant impact was noted for any of the following factors: treatment protocol, radiation dose, surgery. Conclusion: Radiotherapy with and without surgery of Ewing's sarcoma is a highly effective local treatment option. It seems preferable to mutilating surgery. (orig.)

1977-01-01

Minoxidil, a new potent hypotensive agent, was used as the primary antihypertensive agent in 11 patients--10 men and 1 woman aged 35 to 54 years with severe hypertension that was refractory to treatment with maximal (or maximally tolerated) doses of conventional antihypertensive agents. Six patients had severely impaired renal function and three of them were undergoing long-term hemodialysis. The patients were given 2.5 to 40 mg/d of minoxidil for periods of 2 to 29 months. All except one who was almost anuric received propranolol and diuretics. Blood pressure was controlled satisfactorily in all patients. In two patients the hypertension became partially resistant after 1 year of treatment. The main side effects were sodium retention, tachycardia and hirsutism. Renal function remained stable or improved and hemodialysis was discontinued in two patients. Minoxidil is a remarkably potent hypotensive with relatively few side effects and seems particularly advantageous in patients with chronic renal failure. PMID:603847

Down syndrome (DS) is a common genetic cause of intellectual disability yet no pro-cognitive drug therapies are approved for human use. Mechanistic studies in a mouse model of DS (Ts65Dn mice) demonstrate that impaired cognitive function is due to excessive neuronal inhibitory tone. These deficits are normalized by chronic, short-term low doses of GABA A receptor (GABA A R) antagonists in adult animals, but none of the compounds investigated are approved for human use. We explored the therapeutic potential of flumazenil (FLUM), a GABA A R antagonist working at the benzodiazepine binding site that has FDA approval. Long-term memory was assessed by the Novel Object Recognition (NOR) testing in Ts65Dn mice after acute or short-term chronic treatment with FLUM. Short-term, low, chronic dose regimens of FLUM elicit long-lasting (>1week) normalization of cognitive function in both young and aged mice. FLUM at low dosages produces long lasting cognitive improvements and has the potential of fulfilling an unmet therapeutic need in DS. Copyright © 2017. Published by Elsevier Inc.

In recent years, prisons and jails have become de facto psychiatric hospitals, responsible for the care and treatment of individuals with serious mental illness. Historically, cognitive-behaviorally informed therapeutic approaches have been the treatment of choice among mental health practitioners in correctional settings. However, inmate-clients often present with complex diagnostic issues that are arguably better served by long-term treatment options, such as psychodynamic psychotherapy. We first review the nature of psychotherapy in the correctional setting, as well as treatment barriers and challenges faced by both mental health providers and inmate-clients. We then review treatment studies that examine the efficacy of various therapeutic techniques in correctional/forensic contexts. Finally, we argue that, due to the complex nature of psychopathology, average length of time incarcerated, and treatment issues that arise in this multifaceted and challenging setting, mental health treatment providers should consider providing psychodynamic treatment modalities when working with incarcerated individuals. We also argue that more research is needed to examine the efficacy of these treatment approaches with inmate-clients.

Lenalidomide in combination with dexamethasone is an effective and well-established treatment of relapsed or refractory multiple myeloma (rrMM) disease. Due to the scarcity of reports assessing benefit and risk of long-term lenalidomide treatment in non-selected rrMM patients, we retrospectively analysed the long-term outcome in patients with rrMM treated with lenalidomide and dexamethasone. Sixty-seven patients (pts) who were treated with lenalidomide/dexamethasone for rrMM in the approved indication from 2007 to 2011 were included in this retrospective, single-centre analysis. Kaplan-Meier survival estimates were compared between total population, patients on lenalidomide for more than 12 months (mo) and patients discontinuing therapy earlier than 12 months. Median overall survival (OS) of the total patient population was 33.2 mo. OS of pts treated beyond 12 mo was 42.9 mo compared to 20.2 mo (p = 0.027) for pts stopping lenalidomide earlier than 12 mo for other reasons than progression disease (PD). OS of pts >12 mo on lenalidomide treatment did not significantly differ between pts who had received previous autologous transplantation, allogeneic transplantation or conventional therapy. Main non-hematologic toxicities were infections of grade 3/4 in 25 % and thrombembolic events of all grades in 18 % of patients. To the best of our knowledge, this is the first report on feasibility and efficacy of long-term lenalidomide treatment in a non-selected patient cohort. OS of pts >12 mo on lenalidomide is superior when compared to pts discontinued earlier for reasons other than PD. Our data confirm the current use of lenalidomide as a continuous long-term treatment strategy.

Full Text Available 【Abstract】Objective: Talar body fractures are rare and have poor treatment outcome. The purpose of this study is to report the long term surgical treatment outcome of closed talar dome fractures. Methods: Eight closed talar body fractures, treated by open reduction and internal fixation with small fragment cancellous screws and/or Herbert screws in our level I trauma centre were retrospectively analyzed. Preoperative and postoperative radiographs of the foot (antero-posterior, lateral and oblique views and ankle (antero-posterior, lateral and mortise views were obtained. The patients were followed up both radiologically and functionally (foot function index, FFI after 3 weeks, 6 weeks, 3 months, 6 months and then annually. Results: There were five crush fractures and three shear fractures (two sagittal shear and one coronal shear, with average follow-up of 5 years. No early complications were noticed in these patients. Late complications included osteoarthrosis of subtalar/ankle joints in six patients and osteonecrosis of talar body in four patients. On functional assessment, mean FFI after 5 years was 104.63 points and worse outcome was noticed in crush injury and coronal shear fractures. Sagittal shear fractures had a good functional and radiological outcome. Conclusions: Late complications subsequent to surgically treated talar body fractures are inevitable, even though exact reduction and rigid fixation are achieved, thus patients are supposed to be counseled about the adverse outcome. Although crush and coronal shear fractures have poor outcome, sagittal injuries have good prognosis on long term evaluation. Key words: Fractures, bone; Talus; Fracture fixation, internal

Long-term storage of Greater-Than-Class C Low-Level Waste

International Nuclear Information System (INIS)

Magleby, M.T.

1990-01-01

Under Federal law, the Department of Energy (DOE) is responsible for safe disposal of Greater-Than-Class C Low-Level Waste (GTCC LLW) generated by licenses of the Nuclear Regulatory commission (NRC) or Agreement States. Such waste must be disposed of in a facility licensed by the NRC. It is unlikely that licensed disposal of GTCC LLW will be available prior to the year 2010. Pending availability of disposal capacity, DOE is assessing the need for collective, long-term storage of GTCC LLW. Potential risks to public health and safety caused by long-term storage of GTCC LLW at the place of generation will be evaluated to determine if alternative facilities are warranted. If warranted, several options will be investigated to determine the preferred alternative for long-term storage. These options include modification of an existing DOE facility, development of a new DOE facility, or development of a facility by the private sector with or without DOE support. Reasonable costs for long-term storage would be borne by the waste generators. 5 refs., 1 fig

Fusion energy in context: its fitness for the long term

International Nuclear Information System (INIS)

Holdren, J.P.

1978-01-01

Long-term limits to growth in energy will be imposed not by inability to expand supply, but by the rising environmental and social costs of doing so. These costs will therefore be cental issues in choosing long-term options. Fusion, like solar energy, is not one possibility but many, some with very attractive environmental characteristics and others perhaps little better in these regards than fission. None of the fusion options will be cheap, and none is likely to be widely available before the year 2010. The most attractive forms of fusion may require greater investments of time and money to achieve, but they are the real reason for wanting fusion at all

Few studies have investigated the impact of diabetes mellitus (DM), a globally increasing metabolic disease, on treatment outcomes and long-term survival in patients with multidrug-resistant forms of tuberculosis (MDR-TB). We analyzed outcomes in a large cohort to assess the impact of DM on treatment outcomes of patients with MDR-TB. MDR-TB patients newly diagnosed or retreated between 2000 and 2002 and followed for 8-11 years were retrospectively analyzed with respect to the effect of DM as a comorbidity on their treatment outcome and long-term survival. Of 1,407 patients with MDR-TB, 239 (17.0%) had coexisting DM. The mean age and body mass index were higher in MDR-TB patients with DM [MDR-TBDM(+)] than in those without DM [MDR-TBDM(-)]. Patients with MDR-TB and a comorbidity of DM had a significantly lower treatment success rate than those without a history of DM (36.0 vs. 47.2%, p = 0.002). In addition, DM was the negative predictor for MDR-TB treatment success in multivariate analyses [odds ratio 0.51, 95% confidence interval (CI) 0.26-0.99]. Mean survival times were also lower in MDR-TBDM(+) than in MDR-TBDM(-) patients (102 vs. 114 months, p = 0.001), with DM as a significant predictor of poor long-term survival in multivariate analyses (hazard ratio 1.59, 95% CI 1.01-2.50). Among MDR-TB patients, DM was a relatively common comorbidity. In patients undergoing treatment for MDR-TB and followed for 8-11 years, it was found to be independently associated with an increased risk of both treatment failure and death. Copyright © 2013 S.

We investigated the effects of long- and short-term interdisciplinary treatment approaches for reducing symptoms and improving health-related quality of life (HRQoL) and physical functions of patients with fibromyalgia and compared the effects of two different interdisciplinary treatment approaches. We conducted a prospective, randomized, controlled trial involving 66 women with fibromyalgia eligible for the study at a university hospital setting. The patients were randomized into three groups (allocation ratio 1:1:1) using a computer-generated random numbers: a long-term interdisciplinary treatment group (LG, n = 22) that participated in 10 sessions (3-h once-weekly session for 10 weeks) of cognitive behavioral therapy (CBT) together with exercise training and other fibromyalgia related educational programs (two full days); a short-term interdisciplinary treatment group (SG, n = 22) that received two full days of educational, exercise, and CBT programs; and a control group (CG, n = 22). The patients were evaluated at baseline and 6 months after treatment using the visual analog scale (pain, fatigue, and sleep), Fibromyalgia Impact Questionnaire, Beck Depression Inventory, Short Form-36, tender point numbers, and pressure algometry as primary outcomes. The statistical analysis was confined to the 'per-protocol' set. No blinding was performed. The number of patients analyzed was 21 in the LG, 19 in the SG, and 19 in the CG.

Extracorporeal shock wave lithotripsy (ESWL) combined with endotherapy (ET) is the standard treatment for pancreatic duct stones (PDS) in chronic pancreatitis (CP). Our aim was to report the short- and long-term results of ESWL and ET. Consecutively treated 83 patients with symptomatic PDS using ESWL and ET. Success was defined (i) technically: PDS fragmentation and clearance obtained and (ii) clinically: improvement/resolution of pain. To get information on quality of life, we conducted a phone survey whereby we contacted 64 (89%) patients. The long-term results are presented in those patients with ≥2 years follow-up. Treated PDS with median size of 10 (5-25) mm were located in the head, body, or the tail of the pancreas in 78, 4, and 1 patients, respectively. The primary results were that technical success was achieved in 69 patients (83%) and clinical success in 66 patients (80%). Fourteen patients had technical failure, but eight of them became free of pain. Thus, clinical success can be considered to have been achieved in 74 of 83 patients (89%). In patients with persistent pseudocyst (PC) at the time of ESWL (n = 19), the PC disappeared in a year in 14 patients (74%). The long-term results were obtained from 61 (73%) ESWL- and ET-treated patients. The median follow-up for them was 53 months (range: 24-124) and 57 patients (93%) became pain-free or had less pain. For patients with CP and PDS ESWL combined with ET is an effective and safe treatment giving favorable long-term results.

Purpose: To collect data on the health-related quality of life (QOL) of long-term survivors and to determine to what extent QOL might be an appropriate end point in the comparison of treatment options in oropharyngeal carcinoma. Methods and Materials: All patients treated between 1992 and 1998, in two French comprehensive cancer centers, by brachytherapy (BT) ± external beam radiotherapy (EBRT) or surgery plus RT, or exclusive EBRT for T1-T3 (International Union Against Cancer staging system) oropharynx squamous cell carcinoma, were included. QOL was measured once in disease-free patients at least 2 years after treatment initiation. The European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire and the specific H and N35 module were self-administered by all participating patients. Sociodemographic data were collected using a questionnaire specifically designed for the study. The association between the QOL scores of the various treatment-, disease-, and patient-related variables was performed through bivariate analysis and then by multivariate analysis. The mean QOL scores of the EORTC QLQ-C30 questionnaire were compared with the mean scores in the general population. Results: Of the 159 eligible patients, 113 agreed to participate (97 men and 16 women, median age 61 years, range 41-83). The initial treatment was EBRT plus BT in 49 patients, surgery plus RT in 27, and EBRT alone in 37. The median follow-up time was 62 months (range 24-110). Compared with the general population, the three scores indicating the most impaired QOL were emotional and social functioning and fatigue. The clinical significance of global QOL impairment was borderline. The physical functioning, role functioning, and pain scores did not significantly differ from those of the general population. In multivariate analysis, the initial treatment had no significant influence on any dimension of QOL, except global QOL and emotional functioning. Surprisingly, surgery

Long-term potentiation and long-term depression: a clinical perspective

Directory of Open Access Journals (Sweden)

Full Text Available Long-term potentiation and long-term depression are enduring changes in synaptic strength, induced by specific patterns of synaptic activity, that have received much attention as cellular models of information storage in the central nervous system. Work in a number of brain regions, from the spinal cord to the cerebral cortex, and in many animal species, ranging from invertebrates to humans, has demonstrated a reliable capacity for chemical synapses to undergo lasting changes in efficacy in response to a variety of induction protocols. In addition to their physiological relevance, long-term potentiation and depression may have important clinical applications. A growing insight into the molecular mechanisms underlying these processes, and technological advances in non-invasive manipulation of brain activity, now puts us at the threshold of harnessing long-term potentiation and depression and other forms of synaptic, cellular and circuit plasticity to manipulate synaptic strength in the human nervous system. Drugs may be used to erase or treat pathological synaptic states and non-invasive stimulation devices may be used to artificially induce synaptic plasticity to ameliorate conditions arising from disrupted synaptic drive. These approaches hold promise for the treatment of a variety of neurological conditions, including neuropathic pain, epilepsy, depression, amblyopia, tinnitus and stroke.

2011-03-01

It is still debated which treatment modality for Graves' hyperthyroidism (GH) is most appropriate when Graves' orbitopathy (GO) is present. The preference in our center has been always to continue antithyroid drugs for GH (as the block-and-replace [B-R] regimen) until all medical and/or surgical treatments for GO are concluded and the eye disease does not require any further therapy (except prescription of lubricants). This usually takes more than 2 years. The aim of this study was to evaluate the outcome of long-term B-R regimen for GH in GO patients by assessment (after discontinuation of B-R) of (a) the recurrence rate of GH and (b) the relapse rate of GO and its association with recurrent GH and/or (131)I therapy. A retrospective follow-up study was done among all patients referred to the Academic Medical Center in Amsterdam between 1995 and 2005 for GO. The inclusion criteria for the study were a history of GH and GO and a history of treatment for GH with a B-R regimen for more than 2 years. The exclusion criteria were a history of (131)I therapy or thyroidectomy before the end of GO treatment. A questionnaire was sent to 255 patients and returned by 114. Of these patients, 73 qualified for the study. Recurrences of GH and/or GO as indicated by returned questionnaires were checked with treating physicians. Patients were treated with B-R for a median of 41 months (range: 24-132). The median follow-up after discontinuation of the B-R regimen was 57 months (range: 12-170). Recurrent GH occurred in 27 of the 73 study patients (37%) at a median of 3 months (range: 1-65) after withdrawal of antithyroid drug therapy. Nineteen of the 27 patients with recurrent hyperthyroidism were treated with (131)I therapy. A relapse of GO was not encountered in any of the 73 patients. The study suggests that long-term B-R treatment of GH in GO patients is associated with a recurrence rate of hyperthyroidism of about 37%. With the regimen employed, recurrence of hyperthyroidism and

Boosted protease inhibitors (PIs), including ritonavir-boosted atazanavir (ATV/r), are a recommended option for the initial treatment of HIV-1 infection based upon clinical trial data; however, long-term real-life clinical data are limited. We evaluated the long-term use of ATV/r as a component of antiretroviral combination therapy in the real-life setting in the REMAIN study. This was an observational cohort study conducted at sites across Germany, Portugal, and Spain. Retrospective historical and prospective longitudinal follow-up data were extracted every six months from medical records of HIV-infected treatment-naïve patients aged ≥ 18 years initiating a first-line ATV/r-containing regimen. Eligible patients (n = 517) were followed up for a median of 3.4 years. The proportion remaining on ATV/r at 5 years was 51.5% with an estimated Kaplan-Meier median time to treatment discontinuation of 4.9 years. Principal reasons for discontinuation were adverse events (15.9%; 8.9% due to hyperbilirubinemia) and virologic failure (6.8%). The Kaplan-Meier probability of not having virologic failure (HIV-1 RNA treatment-emergent major PI resistance occurred. ATV/r was generally well tolerated during long-term treatment with no significant changes in estimated glomerular filtration rate over five years. In a real-life clinical setting over five years, treatment-naïve patients with HIV-1 infection initiating an ATV/r-based regimen showed sustained virologic suppression, an overall treatment persistence rate of 51.5%, an absence of treatment-emergent major PI resistance mutations at virologic failure, a long-term safety profile consistent with that observed in clinical trials, and no significant decline in renal function.

With improved childhood cancer cure rate, long term sequelae are becoming an important factor of quality of life. Signs of cardiovascular disease are frequently found in long term survivors of cancer. Cardiac damage may be related to irradiation and chemotherapy. We have evaluated simultaneous influence of a series of independent variables on the late cardiac damage in childhood cancer survivors in Slovenia and identified groups at the highest risk. 211 long-term survivors of different childhood cancers, at least five years after treatment were included in the study. The evaluation included history, physical examination, electrocardiograpy, exercise testing and echocardiograpy. For analysis of risk factors, beside univariate analysis, multivariate classification tree analysis statistical method was used. Patients treated latest, from 1989–98 are at highest risk for any injury to the heart (73%). Among those treated earlier are at the highest risk those with Hodgkin's disease treated with irradiation above 30 Gy and those treated for sarcoma. Among specific forms of injury, patients treated with radiation to the heart area are at highest risk of injury to the valves. Patients treated with large doses of anthracyclines or concomitantly with anthracyclines and alkylating agents are at highest risk of systolic function defect and enlarged heart chambers. Those treated with anthracyclines are at highest risk of diastolic function defect. The time period of the patient's treatment is emerged as an important risk factor for injury of the heart

Background Gastroesophageal reflux disease (GERD) is a chronic symptomatic condition and may be associated with erosive esophagitis (EE). Considerable data on the long-term maintenance of healing of EE are available, but data on long-term GERD symptom prevention and patient quality of life (QOL) are limited. Aims To investigate QOL in subjects with healed EE who received 12 months of double-blind maintenance treatment with lansoprazole or ranitidine, followed by long-term open-label lansoprazole therapy to prevent recurrence of EE. Methods Subjects with healed EE received 12 months of double-blind maintenance treatment with lansoprazole 15 mg once daily or ranitidine 150 mg twice daily, followed by dose-titrated, open-label lansoprazole therapy for up to 82 months. Results During double-blind treatment (n = 206), lansoprazole-treated patients showed significantly (P ≤ 0.05) greater improvements than ranitidine-treated patients in the frequency, severity, and ‘bothersomeness’ of heartburn, the symptom index, problems of activity limitation, eating and drinking problems, symptom problems, health distress, and social functioning. During dose-titrated, open-label treatment (n = 195), all disease-specific QOL scales except sleep improved significantly (P lansoprazole for 12 months in healed EE subjects produced significantly greater improvements in QOL indicators than ranitidine. These improvements were sustained during dose-titrated, open-label lansoprazole treatment. PMID:19582579

Sleep-disordered breathing (SDB) and Cheyne-Stokes respiration (CSR) are associated with shorter survival in patients with heart failure. A novel treatment method for this patient group is unilateral phrenic nerve stimulation by the remedē® system (Respicardia Inc., Minnetonka, MN, USA), a transvenously implantable neurostimulation device, which has recently been studied in a large randomized, controlled trial. Previous literature has shown efficacy and safety of the treatment with this first-generation device, but hardly any data are available on long-term clinical parameters, the remedē® device's battery lifetime, device exchangeability, lead position stability, surgical accessibility, and manageability. We performed remedē® device replacements in consecutive patients for battery depletion, and documented clinical parameters, longevity, operation procedure, complications, and difficulties. All patients were on neurostimulation treatment by phrenic nerve neurostimulation when device replacement became necessary. Apnea-hypopnea index (from 45 ± 4/h to 9 ± 4/h), oxygen-desaturation index (from 35 ± 7/h to 7 ± 6/h), and time spent with oxygen saturation of ray documentation of stable lead positions in a long-term setting, no radiation or contrast dye usage was needed and no major complications occurred. In addition, clinical exercise capacity and sleepiness symptoms improved. Novel remedē® device shows sustained therapy efficacy and safety in terms of stable lead positions over 4 years. Long-term phrenic nerve neurostimulation therapy for central SDB/CSR appears feasible in a clinical routine setting. © 2017 Wiley Periodicals, Inc.

Chronic anal fissure is a frequent and disabling disease, often affecting young adults. Botulinum toxin and lateral internal sphincterotomy are the main therapeutic options for refractory cases. Botulinum toxin is minimally invasive and safer compared with surgery, which carries a difficult post-operative recovery and fecal incontinence risk. The long-term efficacy of Botulinum toxin is not well known. The aim of this study was to evaluate the long-term efficacy and safety of Botulinum toxin in the treatment of chronic anal fissure. This was a retrospective study at a single center, including patients treated with Botulinum toxin from 2005 to 2010, followed over at least a period of 5 years. All patients were treated with injection of 25U of Botulinum toxin in the intersphincteric groove. The response was registered as complete, partial, refractory and relapse. Botulinum toxin was administered to 126 patients, 69.8% ( n  = 88) were followed over a period of 5 years. After 3 months, 46.6% ( n  = 41) had complete response, 23.9% ( n  = 21) had partial response and 29.5% ( n  = 26) were refractory. Relapse was observed in 1.2% ( n  = 1) at 6 months, 11.4% ( n  = 10) at 1 year, 2.3% ( n  = 2) at 3 years; no relapse at 5 years. The overall success rate was 64.8% at 5 years of follow-up. Botulinum toxin was well tolerated by all patients and there were no complications. The use of Botulinum toxin to treat patients with chronic anal fissure was safe and effective in long-term follow-up.

To evaluate the stability of the outcomes of mandibular cervical headgear (MCH) and fixed appliance-treated Class III patients at a long-term posttreatment (5 years) observation, compared with well-matched untreated Class III controls, following a previous report on the short-term outcomes of this protocol. The treated group consisted of 20 patients with dentoskeletal Class III malocclusions treated with a two-phase protocol consisting of MCH and fixed appliances, while the control group comprised 18 untreated subjects with similar dentoskeletal Class III malocclusion. Lateral cephalograms of both patients and controls were analyzed at two time points: posttreatment (PT), after two-phase treatment; and long term (LT). All patients were at a postpubertal stage of skeletal maturity at PT, and they showed CS6 at LT, thus revealing completion of pubertal craniofacial growth. In the long term, the treatment group showed significantly smaller values for mandibular length (Co-Gn), SNB angle, maxillomandibular differential, and molar relation. When compared with the controls, the treated patients exhibited also greater values for ANB angle, Wits appraisal, and overjet at LT. No significant difference between the two groups was found for the changes occurring from PT to LT. Favorable dentoskeletal outcomes induced by MCH and fixed appliances remained stable in the long term; untreated Class III malocclusion did not show any tendency toward self-improvement during the postpubertal interval.

Medulloblastoma is highly radioresponsive, and recent treatment results have improved greatly since the introduction of megavoltage machine in 1960s. There is increasing evidence for the potential cure of medulloblastoma if properly treated in its early stages. The curable group represents approximately 75% of diagnosed patients. Long-term treatment effects were examined in this study. The study reveals age-dependent late effects in learning ability; the patients less than 4-years-old at treatment had major learning problems; patients of 5 to 7 years old performed at satisfactory-to-low passing levels in school work; patients older than 8 years old had no major intellectual impairment. Short stature was common when growth potential was present at the time of therapy, but endocrine tests were generally negative. These observations indicate special educational requirement needs, especially for children treated at a young age

Medical Underwriting In Long-Term Care Insurance: Market Conditions Limit Options For Higher-Risk Consumers.

2016-08-01

A key feature of private long-term care insurance is that medical underwriters screen out would-be buyers who have health conditions that portend near-term physical or cognitive disability. We applied common underwriting criteria based on data from two long-term care insurers to a nationally representative sample of individuals in the target age range (50-71 years) for long-term care insurance. The screening criteria put upper bounds on the current proportion of Americans who could gain coverage in the individual market without changes to medical underwriting practice. Specifically, our simulations show that in the target age range, approximately 30 percent of those whose wealth meets minimum industry standards for suitability for long-term care insurance would have their application for such insurance rejected at the underwriting stage. Among the general population-without considering financial suitability-we estimated that 40 percent would have their applications rejected. The predicted rejection rates are substantially higher than the rejection rates of about 20-25 percent of applicants in the actual market. In evaluating reforms for long-term care financing and their potential to increase private insurance rates, as well as to reduce financial pressure on public safety-net programs, policy makers need to consider the role of underwriting in the market for long-term care insurance.

Neural Rhythms of Change: Long-Term Improvement after Successful Treatment in Children with Disruptive Behavior Problems

Directory of Open Access Journals (Sweden)

Steven Woltering

2015-01-01

Full Text Available Neural changes were investigated for children with disruptive behavior problems one year after a treatment program ended. Thirty-nine children and their parents visited the research lab before, after, and a year after treatment ended. During those lab visits, electroencephalography (EEG was recorded during a challenging Go/No-go task. Treatment consisted of intensive 14-week combined cognitive behavioral therapy and parent management training sessions. For the analysis, participants were divided into long-term improvers (IMPs and long-term nonimprovers (NIMPs based on changes in their externalizing problem scores. The results showed early no-go theta power (4–8 Hz, 100–250 ms decreased for long-term IMPs compared to NIMPs. When participants were divided based on changes in their comorbid internalizing symptoms, effects were stronger and reductions in theta power were found for early as well as later phases (250–650 ms. We provided preliminary evidence that theta power is a useful neural measure to trace behavioral change linked to improved self-regulation even up to a year after treatment ended. Results may have implications for the characterization of children with disruptive behavior problems and may lead to the development of novel markers of treatment success.

Few studies exist on the long-term effect of treatment of trauma-affected refugees. The purpose of this study was to estimate the long-term treatment effects of cognitive behavioural therapy and antidepressants (sertraline and mianserin) in trauma-affected refugees. Follow-ups were conducted 6 and 18 months after a randomised controlled clinical trial. The included patients were refugees with war-related traumatic experiences, PTSD and without psychotic disorders. We found a small improvement over time in PTSD, depression and anxiety symptoms and level of functioning, but the improvement was not associated with any specific treatment. Personality change after catastrophic experiences and life events influenced the symptom level at all follow-ups while depression at completion of treatment was associated with a steeper decline in symptom load at the follow-ups. In spite of the limited decline in symptom scores and treatment effects immediately after treatment, the condition of the treated trauma-affected refugees was significantly improved 6 and 18 months after treatment although the improvement was small.

Cell-based neurotrophin treatment supports long-term auditory neuron survival in the deaf guinea pig.

Gillespie, Lisa N; Zanin, Mark P; Shepherd, Robert K

2015-01-28

The cochlear implant provides auditory cues to profoundly deaf patients by electrically stimulating the primary auditory neurons (ANs) of the cochlea. However, ANs degenerate in deafness; the preservation of a robust AN target population, in combination with advances in cochlear implant technology, may provide improved hearing outcomes for cochlear implant patients. The exogenous delivery of neurotrophins such as brain-derived neurotrophic factor (BDNF) and neurotrophin-3 is well known to support AN survival in deafness, and cell-based therapies provide a potential clinically viable option for delivering neurotrophins into the deaf cochlea. This study utilized cells that were genetically modified to express BDNF and encapsulated in alginate microspheres, and investigated AN survival in the deaf guinea pig following (a) cell-based neurotrophin treatment in conjunction with chronic electrical stimulation from a cochlear implant, and (b) long-term cell-based neurotrophin delivery. In comparison to deafened controls, there was significantly greater AN survival following the cell-based neurotrophin treatment, and there were ongoing survival effects for at least six months. In addition, functional benefits were observed following cell-based neurotrophin treatment and chronic electrical stimulation, with a statistically significant decrease in electrically evoked auditory brainstem response thresholds observed during the experimental period. This study demonstrates that cell-based therapies, in conjunction with a cochlear implant, shows potential as a clinically transferable means of providing neurotrophin treatment to support AN survival in deafness. This technology also has the potential to deliver other therapeutic agents, and to be used in conjunction with other biomedical devices for the treatment of a variety of neurodegenerative conditions.

2010-10-01

Octreotide has been suggested as a medical treatment option in refractory cases of primary intestinal lymphangiectasia (IL). There are few data about the long-term effect and safety of octreotide for IL in the literature. In the present article we analyzed pediatric cases of primary IL with long-term octreotide treatment and discussed its safety profile. Between 1999 and 2008, 13 children were diagnosed in our clinic as having IL. Six patients with primary IL were followed up, receiving octreotide therapy. The clinical data of the patients and duration of therapy, dose, and side effects of octreotide were evaluated. Octreotide, 15 to 20 μg per body weight 2 times daily subcutaneously, was given to all of the patients. Duration of the octreotide treatment changed between 3 and 37 months. Stool frequency decreased in all of the patients after starting octreotide treatment. Serum albumin could be maintained at normal levels in 3 patients. The requirement of albumin infusions decreased in all of the patients. Acute pancreatitis was observed as a side effect of octreotide in 1 patient. Octreotide may help to maintain serum albumin levels, improve clinical findings, and decrease the requirement of albumin infusions in refractory cases of primary IL.

Background: Recalcitrant lateral epicondylitis (elbow extensor–origin tendinosis) is a common cause of elbow pain with many treatment options. In the present study, the medium-term results after open release and radiofrequency microtenotomy are reported. Hypothesis: Microtenotomy would provide long-term pain relief that was as good as the open release method. Study Design: Prospective, randomized trial. Methods: Twenty-four patients randomized to either open release or microtenotomy were assessed after 5 to 7 years. Clinical examination and dynamic infrared thermography (DIRT) of both elbows were performed preoperatively and at the medium-term follow-up. Magnetic resonance imaging (MRI) of both elbows was performed at the medium-term follow-up. Results: Significant pain reduction was found using a visual analog scale (VAS) at the medium-term follow-up in both groups compared with the preoperative assessment (P lateral epicondylitis. The hypothesis was thus verified. PMID:26535247

To analyze the long-term skeletal and dentoalveolar effects and to evaluate treatment timing of Class II treatment with functional appliances followed by fixed appliances. A group of 40 patients (22 females and 18 males) with Class II malocclusion consecutively treated either with a Bionator or an Activator followed by fixed appliances was compared with a control group of 20 subjects (9 females and 11 males) with untreated Class II malocclusion. Lateral cephalograms were available at the start of treatment (mean age 10 years), end of treatment with functional appliances (mean age 12 years), and long-term observation (mean age 18.6 years). The treated sample also was divided into two groups according to skeletal maturity. The early-treatment group was composed of 20 subjects (12 females and 8 males) treated before puberty, while the late-treatment group included 20 subjects (10 females and 10 males) treated at puberty. Statistical comparisons were performed with analysis of variance followed by Tukey's post hoc tests. Significant long-term mandibular changes (Co-Gn) in the treated group (3.6 mm over the controls) were associated with improvements in the skeletal sagittal intermaxillary relationship, overjet, and molar relationship (∼3.0-3.5 mm). Treatment during the pubertal peak was able to produce significantly greater increases in total mandibular length (4.3 mm) and mandibular ramus height (3.1 mm) associated with a significant advancement of the bony chin (3.9 mm) when compared with treatment before puberty. Treatment of Class II malocclusion with functional appliances appears to be more effective at puberty.

Vaccines against drugs of abuse: a viable treatment option?

Science.gov (United States)

Kantak, Kathleen M

2003-01-01

Drug addiction is a chronically relapsing brain disorder. There is an urgent need for new treatment options for this disease because the relapse rate among drug abusers seeking treatment is quite high. During the past decade, many groups have explored the feasibility of using vaccines directed against drugs of abuse as a means of eliminating illicit drug use as well as drug overdose and neurotoxicity. Vaccines work by inducing drug-specific antibodies in the bloodstream that bind to the drug of abuse and prevent its entry into the brain. The majority of work in this area has been conducted with vaccines and antibodies directed against cocaine and nicotine. On the basis of preclinical work, vaccines for cocaine and nicotine are now in clinical trials because they can offer long-term protection with minimal treatment compliance. In addition, vaccines and antibodies for phencyclidine, methamphetamine and heroin abuse are currently under development. An underlying theme in this research is the need for high concentrations of circulating drug-specific antibodies to reduce drug-seeking and drug-taking behaviour when the drug is repeatedly available, especially in high doses. Although vaccines against drugs of abuse may become a viable treatment option, there are several drawbacks that need to be considered. These include: a lack of protection against a structurally dissimilar drug that produces the same effects as the drug of choice;a lack of an effect on drug craving that predisposes an addict to relapse; and tremendous individual variability in antibody formation. Forced or coerced vaccination is not likely to work from a scientific perspective, and also carries serious legal and ethical concerns. All things considered, vaccination against a drug of abuse is likely to work best with individuals who are highly motivated to quit using drugs altogether and as part of a comprehensive treatment programme. As such, the medical treatment of drug abuse will not be radically

Full Text Available Aim: The aim of this work was: i to evaluate the prevalence of male partners of subfertile couples being treated with long/short term therapies for non andrological diseases; ii to study their seminal profile for the possible effects of their treatments on spermatogenesis and/or epididymal maturation. Methods: The study group was made up of 723 subjects, aged between 25 and 47 years. Semen analysis was performed according to World Health Organization (WHO guidelines (1999. The Superimposed Image Analysis System (SIAS, which is based on the computerized superimposition of spermatozoa images, was used to assess sperm motility parameters. Results: The prevalence of subjects taking pharmacological treatments was 22.7% (164/723. The prevalence was 3.7% (27/723 for the Short-Term Group and 18.9% (137/723 for the Long-Term Group. The subjects of each group were also subdivided into subgroups according to the treatments being received. Regarding the seminal profile, we did not observe a significant difference between the Long-Term, Short-Term or the Control Group. However, regarding the subgroups, we found a significant decrease in sperm number and progressive motility percentage in the subjects receiving treatment with antihypertensive drugs compared with the other subgroups and the Control Group. Conclusions: In the management of infertile couples, the potential negative impact on seminal parameters of any drugs being taken as Long-Term Therapy should be considered. The pathogenic mechanism needs to be clarified.

Natural gas market assessment: Long-term Canadian natural gas contracts

International Nuclear Information System (INIS)

1992-08-01

A descriptive analysis is presented of the changes which have occurred and the developing trends in the long-term Canadian contracts governing the sale of western Canadian gas into the domestic and export markets from 1985 to 1991. The report is limited to domestic and export contracts for Canadian gas and does not include imported gas under contract. Contract structures prior to deregulation, the changing role of long-term contracts, size and duration of long-term contracts, and terms and conditions of long-term contracts are discussed. Important changes since the mid-1980s include: increased flexibility in long-term contracts enabling the parties to respond more readily to changing supply and demand conditions; greater balance between the buyer's obligation to purchase and the seller's obligation to deliver; flexible and increasingly simple pricing terms that track competitive market conditions; shorter contract terms; reduced contract volumes as smaller end-users and producer/marketers enter the market; and unbundling of gas sales and transportation service providing a wider range of contracting choices and options. 36 figs., 2 tabs

Objective: To evaluate the long-term efficacy of CT-guided epidural steroid injection for the treatment of sciatica. Methods: CT-guided epidural steroid injection was performed in 180 patients with sciatica from May 1998 to March 2004, and all patients had failure to previous conservative treatment. Visual analogue scale was used to evaluate the pain of the patient before and after the treatment. Results: Follow-up was taken for 112 cases during 1-6 years after the treatment, 89 patients (79.5%) had successful long-term outcome and 80 patients (71.4%) were satisfied. Conclusions: CT-guided epidural steroid injection can reduce low back pain and radical pain. It should be preferentially considered as the first choice when conservative treatments are failed.

2015-01-01

CONCLUSION: The Xingnao Kaiqiao needling method has a better effect than control treatment in reducing disability rate. The long-term effect of Xingnao Kaiqiao needling against ischemic stroke is better than that of control treatment. However, the limitations of this study limit the strength of the conclusions. Randomized controlled trials with a strict, reasonable design, and multi-center, large-scale samples and follow-up are necessary to draw conclusions about Xingnao Kaiqiao needling.

Long-lasting effects of new Russian psychotropic drugs Noopept and Afobazol on active avoidance conditioning and formation of learned helplessness neurosis were studied on an original experimental model in rats. Noopept eliminated the manifestations of learned helplessness after long-term (21-day) treatment by increasing the percent of trained animals. Afobazol was low effective in preventing manifestations of learned helplessness, but if used for a long time, it reduced the incidence of learned helplessness development by increasing the percent of untrained animals.

The prognosis of metastatic melanoma is poor. Pre-targeted treatment era, the combination of interferon-α (IF-α) plus chemotherapy had been used and have generally short response duration. Herein, we present a metastatic melanoma case that achieved long-term durable complete response (CR) IF-α plus chemotherapy and IF-α maintenance therapy and had lower Regulatory T (Treg) cells. A fifty-year old woman was admitted to the hospital with metastatic melanoma. Lactate dehydrogenase (LDH) level was 660 U/L. The percentage of CD4+CD25+ Treg cells was 2.4% in CD4+ lymphocytes. The IF-α plus chemotherapy and IF-α maintenance were administered. After six courses of chemotherapy, CR was achieved. Vitiligo and hypothyroidism occurred. The patient has remained in CR for approximately 7 years until second pleural metastases were detected and death. The patient has positive prognostic factors such as induction of auto immunity, small tumor volume, mild elevated LDH level, and lower Treg cell percentage. She survived long term with CR after IF-α treatment with concurrent chemotherapy and maintenance. IF-α plus chemotherapy may be a treatment option for metastatic melanoma in selected cases who cannot reach new targeted drugs

Full Text Available Cesar Bustos,1 Aitziber Aguinaga,1 Francisco Carmona-Torre,2 Jose Luis Del Pozo1,3 1Department of Clinical Microbiology, 2Department of Internal Medicine, 3Division of Infectious Diseases, Clinica Universidad de Navarra, Pamplona, Spain Abstract: Since the first description in 1982, totally implanted venous access ports have progressively improved patients' quality of life and medical assistance when a medical condition requires the use of long-term venous access. Currently, they are part of the standard medical care for oncohematologic patients. However, apart from mechanical and thrombotic complications, there are also complications associated with biofilm development inside the catheters. These biofilms increase the cost of medical assistance and extend hospitalization. The most frequently involved micro-organisms in these infections are gram-positive cocci. Many efforts have been made to understand biofilm formation within the lumen catheters, and to resolve catheter-related infection once it has been established. Apart from systemic antibiotic treatment, the use of local catheter treatment (ie, antibiotic lock technique is widely employed. Many different antimicrobial options have been tested, with different outcomes, in clinical and in in vitro assays. The stability of antibiotic concentration in the lock solution once instilled inside the catheter lumen remains unresolved. To prevent infection, it is mandatory to perform hand hygiene before catheter insertion and manipulation, and to disinfect catheter hubs, connectors, and injection ports before accessing the catheter. At present, there are still unresolved questions regarding the best antimicrobial agent for catheter-related bloodstream infection treatment and the duration of concentration stability of the antibiotic solution within the lumen of the port.

Unilateral vocal fold paralysis (UVFP) is a common voice disorder that may cause glottal closure insufficiency with hoarseness of voice. Laryngeal electromyography (LEMG)-guided hyaluronic acid vocal fold (VF) injection has been proposed as a treatment option to improve glottal closure with a satisfactory short-term effect. To our knowledge, this study reports the first long-term follow-up result of this treatment modality. To present the long-term treatment results of LEMG-guided hyaluronic acid VF injection for UVFP. Prospective study of the treatment results of 74 patients who received LEMG-guided hyaluronic acid VF injection for UVFP at a tertiary referral medical center from March 2010 to February 2013. In the office-based procedure, 1.0 mL of hyaluronic acid was injected via a 26-gauge monopolar injectable needle electrode into paralyzed thyroarytenoid muscles by LEMG guidance. Various glottal closure evaluations such as normalized glottal gap area, maximal phonation time, phonation quotient, mean airflow rate, perceptual GRBAS (grade, roughness, breathiness, asthenia, strain) scale, and Voice Handicap Index were compared before and after injection using the nonparametric Wilcoxon signed rank test within 1 month, at 6 months, and at the last follow-up examination. Sixty patients had been followed up for at least 6 months. Forty-four patients received only 1 injection, and 16 patients received repeated injections (2 injections for 13 patients and 3 for 3 patients). All the glottal closure parameters improved significantly (P injection and 16 (22%) who received repeated injections did not require another treatment after long-term follow-up. Laryngeal electromyography-guided hyaluronic acid VF injection is an option for treating UVFP with satisfactory results.

The increasing age of European Nuclear Power Plants (NPPs) and envisaged extensions of plant lifetimes from 40 up to 80 years require an improved understanding of ageing phenomena of RPV components. The Network of Excellence NULIFE (Nuclear Plant Life Prediction) has been established to advance the safe and economic long-term operation (LTO) of NPPs by facilitating increased co-operation for applied R and D amongst members of the European nuclear community. The accurate prediction and management of RPV neutron irradiation embrittlement connected with long-term operation is an important aspect of this co-operation. Phenomena that might become important at high neutron fluences (such as flux effects and late blooming effects) have to be considered adequately in safety assessments. However, the surveillance database for prolonged irradiation times and low neutron fluxes is sparse. Consequently, there are significant uncertainties in the treatment of long-term irradiation effects. Therefore, the project LONGLIFE (Treatment of long-term irradiation embrittlement effects in RPV safety assessment) was initiated under the Euratom 7th Framework Programme of the European Commission as an umbrella project of NULIFE. LONGLIFE aims at 1) improved understanding of long-term irradiation phenomena that might compromise RPV integrity, and thereby the LTO of European NPPs, and 2) assessment of the adequacy of current prediction tools, codes, standards and surveillance guidelines for supporting long-term RPV operation. The scope of the work comprises the analysis of LTO boundary conditions; microstructural investigations and supplementary mechanical tests on RPV steels, including RPV steels from decommissioned plants; training activities; and elaboration of recommendations for RPV materials assessment and embrittlement surveillance under LTO conditions. A key part of the technical work is the selection of relevant materials for examination, e.g. which contain different weld and base

The purpose of this paper is to present some results of the analysis of the possible options for Russian NPPs fuel supply. In the classical consideration these are four fuel cycles: uranium cycle based on natural uranium, this cycle has several economical advantages with the use of CANDU type reactors with a heavy-water moderator; uranium cycle based on enriched uranium, it is a basis for the current and future nuclear power; uranium-thorium fuel cycle with capabilities which are very promising but unfortunately difficult to implement in practice; plutonium-uranium cycle, in terms of its potential capabilities it is an excellent option, but it is extremely difficult to implement it in practice due to a high activity and toxicity of nuclear materials under recycle. The nuclear power of Russia is currently aimed at using the cheapest fuel resources, that is first of all, uranium reprocessed from industrial reactor fuel and slag-heaps accumulated on the past in isotope-separation plant sites. These resources are enough for the Russian large-scale nuclear power to be developed [ru

Long-term psychosocial consequences of surgical congenital malformations.

Diseth, Trond H; Emblem, Ragnhild

2017-10-01

Surgical congenital malformations often represent years of treatment, large number of hospital stays, treatment procedures, and long-term functional sequels affecting patients' psychosocial functioning. Both functional defects and psychosocial difficulties that occur commonly in childhood may pass through adolescence on to adulthood. This overview presents reports published over the past 3 decades to elucidate the long-term psychosocial consequences of surgical congenital malformations. Literature searches conducted on PubMed database revealed that less than 1% of all the records of surgical congenital malformations described long-term psychosocial consequences, but with diverse findings. This inconsistency may be due to methodological differences or deficiencies; especially in study design, patient sampling, and methods. Most of the studies revealed that the functional deficits may have great impact on patients' mental health, psychosocial functioning, and QoL; both short- and long-term negative consequences. Factors other than functional problems, e.g., repeated anesthesia, multiple hospitalization, traumatic treatment procedures, and parental dysfunctioning, may also predict long-term mental health and psychosocial functioning. Through multidisciplinary approach, pediatric surgeons should also be aware of deficits in emotional and psychosocial functioning. To achieve overall optimal psychosocial functioning, the challenge is to find a compromise between physically optimal treatment procedures and procedures that are not psychologically detrimental.

The optimal treatment of spinal dural arteriovenous fistulae (SDAVF) remains controversial and long-term follow-up data, especially data from multidisciplinary treatment, are rarely available. Thus, long-term outcomes following a multidisciplinary approach to the treatment of SDAVF were investigated. The investigation included 26 patients with SDAVF treated at the authors' department over a 15-year period including a follow-up of more than 2 years. The treatment strategy when occlusion of the draining vein could be achieved was to embolize the fistula with Histoacryl, with surgery reserved for those patients unsuitable for embolization. Posttreatment angiography followed by MRI was performed in all patients. Clinical follow-up was performed using the gait and micturition Aminoff-Logue scale scores and the modified Rankin scale score. Embolization was performed in 19 patients (73.1%), and direct surgery in 7 patients (26.9%). Follow-up angiography (at a mean of 21.7 months) showed occlusion of the SDAVF in 24 patients (92.3%). Of the 19 embolized patients, 2 (10.5%) developed recurrence secondary to insufficient occlusion of the SDAVF draining vein, and one of these two patients underwent re-embolization and one re-operation. No negative effects of SDAVF recurrence on the final clinical outcome were identified in either patient. MRI after angiography (at a mean of 91.5 months) demonstrated occlusion of all SDAVFs. After a mean clinical follow-up of 103.4 months there was a statistically significant improvement in both the modified Rankin scale score and the Aminoff-Logue gait scale score (P < 0.05). The present multidisciplinary study showed for the first time that embolization leads to stable neuroradiological results and favourable clinical outcomes even for very long follow-up times of more than 100 months. Microsurgery remains the treatment of choice when safe embolization of the draining vein cannot be achieved. (orig.)

Restoration treatments in urban park forests drive long-term changes in vegetation trajectories.

Municipalities are turning to ecological restoration of urban forests as a measure to improve air quality, ameliorate urban heat island effects, improve storm water infiltration, and provide other social and ecological benefits. However, community dynamics following urban forest restoration treatments are poorly documented. This study examines the long-term effects of ecological restoration undertaken in New York City, New York, USA, to restore native forest in urban park natural areas invaded by woody non-native plants that are regional problems. In 2009 and 2010, we sampled vegetation in 30 invaded sites in three large public parks that were restored 1988-1993, and 30 sites in three large parks that were similarly invaded but had not been restored. Data from these matched plots reveal that the restoration treatment achieved its central goals. After 15-20 years, invasive species removal followed by native tree planting resulted in persistent structural and compositional shifts, significantly lower invasive species abundance, a more complex forest structure, and greater native tree recruitment. Together, these findings indicate that successional trajectories of vegetation dynamics have diverged between restored forests and invaded forests that were not restored. In addition, the data suggest that future composition of these urban forest patches will be novel assemblages. Restored and untreated sites shared a suite of shade-intolerant, quickly-growing tree species that colonize disturbed sites, indicating that restoration treatments created sites hospitable for germination and growth of species adapted to high light conditions and disturbed soils. These findings yield an urban perspective on the use of succession theory in ecological restoration. Models of ecological restoration developed in more pristine environments must be modified for use in cities. By anticipating both urban disturbances and ecological succession, management of urban forest patches can be

Long-term results of total lymphoid irradiation in the treatment of cardiac allograft rejection

Purpose: To evaluate the short and long-term effects of total lymphoid irradiation (TLI) in the treatment of cardiac transplant rejection. Methods and Materials: Between 1986 and 1995, 48 courses of TLI were delivered to 47 cardiac transplant patients. In 37 patients, TLI was administered for intractable allograft rejection despite conventional therapy while 10 patients received TLI prophylactically. The prescribed radiation dose was 8 Gy in 0.8 Gy fractions twice weekly to mantle and inverted-Y plus spleen fields. Postirradiation follow-up ranged from 6 months to 9.1 years, with a mean of 3.1 years. Results: The actual mean dose was 7.3 Gy delivered over a mean of 39 days. Fifty-six percent of patients required treatment delay or abbreviation because of thrombocytopenia, leukopenia, infection, or unrelated problems. In patients treated for intractable rejection, rejection rates dropped from 0.46 to 0.14 and to 0.06 episodes/patient/month before, during, and after TLI (p < 0.0001). Rejection rates continued to drop throughout follow-up. Prednisone requirements decreased from 0.41 mg/kg before treatment to 0.21 mg/kg afterward (p < 0.0001). The ratio of helper to cytotoxic-suppressor T-cells decreased during TLI from 1.33 to 0.89, and remained low at 0.44, 2-4 months after treatment. Infection rates were not increased and two patients developed malignancy. Rejection rates were high during prophylactic treatment and this protocol was abandoned. Three-year actuarial survival after irradiation was 60% for patients with intractable rejection and 70% for the prophylactic cohort. Conclusion: TLI is an effective treatment for control of intractable cardiac rejection. Episodes of rejection and steroid dosage requirements are decreased for up to 9.1 years. A possible mechanism of action is long term alteration in T-lymphocyte subsets. Patients experience transient bone marrow suppression but no increase in infection or bleeding. Long-term complications of TLI are not

Spiral ganglion neurons (SGNs), the target cells of the cochlear implant, undergo gradual degeneration following loss of the sensory epithelium in deafness. The preservation of a viable population of SGNs in deafness can be achieved in animal models with exogenous application of neurotrophins such as brain-derived neurotrophic factor (BDNF) and neurotrophin-3. For translation into clinical application, a suitable delivery strategy that provides ongoing neurotrophic support and promotes long-term SGN survival is required. Cell-based neurotrophin treatment has the potential to meet the specific requirements for clinical application, and we have previously reported that Schwann cells genetically modified to express BDNF can support SGN survival in deafness for 4 weeks. This study aimed to investigate various parameters important for the development of a long-term cell-based neurotrophin treatment to support SGN survival. Specifically, we investigated different (i) cell types, (ii) gene transfer methods and (iii) neurotrophins, in order to determine which variables may provide long-term neurotrophin expression and which, therefore, may be the most effective for supporting long-term SGN survival in vivo. We found that fibroblasts that were nucleofected to express BDNF provided the most sustained neurotrophin expression, with ongoing BDNF expression for at least 30 weeks. In addition, the secreted neurotrophin was biologically active and elicited survival effects on SGNs in vitro. Nucleofected fibroblasts may therefore represent a method for safe, long-term delivery of neurotrophins to the deafened cochlea to support SGN survival in deafness. Copyright © 2014 IBRO.

Cachexia and pancreatic cancer: Are there treatment options?

Science.gov (United States)

Mueller, Tara C; Burmeister, Marc A; Bachmann, Jeannine; Martignoni, Marc E

2014-01-01

Cachexia is frequently described in patients with pancreatic ductal adenocarcinoma (PDAC) and is associated with reduced survival and quality of life. Unfortunately, the therapeutic options of this multi-factorial and complex syndrome are limited. This is due to the fact that, despite extensive preclinical and clinical research, the underlying pathological mechanisms leading to PDAC-associated cachexia are still not fully understood. Furthermore, there is still a lack of consensus on the definition of cachexia, which complicates the standardization of diagnosis and treatment as well as the analysis of the current literature. In order to provide an efficient therapy for cachexia, an early and reliable diagnosis and consistent monitoring is required, which can be challenging especially in obese patients. Although many substances have been tested in clinical and preclinical settings, so far none of them have been proven to have a long-term effect in ameliorating cancer-associated cachexia. However, recent studies have demonstrated that multidimensional therapeutic modalities are able to alleviate pancreatic cancer-associated cachexia and ultimately improve patients’ outcome. In this current review, we propose a stepwise and pragmatic approach to facilitate and standardize the treatment of cachexia in pancreatic cancer patients. This strategy consists of nutritional, dietary, pharmacological, physical and psychological methods. PMID:25071331

Bronchopulmonary Dysplasia: Chronic Lung Disease of Infancy and Long-Term Pulmonary Outcomes

2017-01-01

Full Text Available Bronchopulmonary dysplasia (BPD is a chronic lung disease most commonly seen in premature infants who required mechanical ventilation and oxygen therapy for acute respiratory distress. While advances in neonatal care have resulted in improved survival rates of premature infants, limited progress has been made in reducing rates of BPD. Lack of progress may in part be attributed to the limited therapeutic options available for prevention and treatment of BPD. Several lung-protective strategies have been shown to reduce risks, including use of non-invasive support, as well as early extubation and volume ventilation when intubation is required. These approaches, along with optimal nutrition and medical therapy, decrease risk of BPD; however, impacts on long-term outcomes are poorly defined. Characterization of late outcomes remain a challenge as rapid advances in medical management result in current adult BPD survivors representing outdated neonatal care. While pulmonary disease improves with growth, long-term follow-up studies raise concerns for persistent pulmonary dysfunction; asthma-like symptoms and exercise intolerance in young adults after BPD. Abnormal ventilatory responses and pulmonary hypertension can further complicate disease. These pulmonary morbidities, combined with environmental and infectious exposures, may result in significant long-term pulmonary sequalae and represent a growing burden on health systems. Additional longitudinal studies are needed to determine outcomes beyond the second decade, and define risk factors and optimal treatment for late sequalae of disease.

Patellar tendinopathy is a condition characterized by anterior knee activity-related pain. It has a high incidence among athletes engaged in jumping sports and may become a chronic condition. Nonoperative management is the first choice in these patients, and several nonsurgical treatment options have been proposed. Nonetheless, clear indications on the most effective approach to address patellar tendinopathy are still lacking. To analyze the evidence on nonoperative options to treat chronic patellar tendinopathy through a systematic review of the literature and to perform a meta-analysis to identify the most effective nonsurgical option. Systematic review and meta-analysis. The search was conducted with the PubMed and Cochrane databases on January 4, 2017. All clinical English-language reports of any level of evidence on nonsurgical treatment of patellar tendinopathy were included. The quality of each article was assessed by use of the Coleman score. A meta-analysis was performed on all articles reporting the Victorian Institute of Sport Assessment scale for patellar tendinopathy to evaluate the results of the most described treatments. A total of 70 studies involving 2530 patients were included in the qualitative data synthesis. The Coleman score showed an overall poor study quality. The most described treatment groups that could be included in the meta-analysis were reported in 22 studies on eccentric exercise, extracorporeal shockwave therapy (ESWT), and platelet-rich plasma (PRP). Single and multiple PRP injections were evaluated separately. Eccentric exercise therapies obtained the best results ( P patellar tendinopathy with important limitations in terms of study quality. The available evidence showed an overall positive outcome, but some differences have been highlighted. Eccentric exercises may seem the strategy of choice in the short-term, but multiple PRP injections may offer more satisfactory results at long-term follow-up and can be therefore considered

Congenital coxa vara (CCV) is a rare hip condition with few long-term studies. The purpose of this study was to assess clinical, radiographic, and functional outcomes after operative and nonoperative treatment of CCV, assess reliability of radiographic parameters, and investigate risk factors for recurrence after surgery. Retrospective review was performed of all CCV patients treated at 1 institution from 1980 to 2010. In addition, patients were recalled for additional follow-up x-rays, modified Harris Hip Score (mHHS), and gait analysis. Radiographic measurements [neck-shaft angle (NSA), head-shaft angle (HSA), Hilgenreiner-epiphyseal angle (HEA), and femoral neck length (FNL)] were assessed for reliability using intraclass correlation coefficients. Multivariate analysis was performed to identify risk factors for recurrence after surgery. Forty-six hips in 32 patients were reviewed. Mean age at presentation was 5.4±4.9 years. Mean follow-up was 11.8±5.8 years. Valgus proximal femoral osteotomy was performed in 27 hips (20 patients). Initial deformity was greater in the operative group (NSA 90±17 degrees, HEA 68±19 degrees) versus nonoperative patients (NSA 122±19 degrees, HEA 34±14 degrees) (PNSA occurred in only 21%. In contrast, 56% of operative hips showed decreased FNL growth rates. Interobserver reliability was excellent for HEA (0.98), NSA (0.90), and FNL (0.89), and good for HSA (0.79). Repeat osteotomy was performed in 6 cases (22%). No significant predictors for recurrence were identified. At long-term follow-up for recalled patients, 72% had significantly abnormal gait, and 50% had fair-poor functional outcomes (mHHSNSA are the most reliable radiographic measurements of proximal femoral deformity in CCV. Recurrence is not uncommon, but no predictors were identified. Many patients have persistent gait abnormalities and functional impairment at long-term follow-up, regardless of prior treatment.

Epithelioid hemangioendothelioma is a rare vascular tumor of borderline or low-grade malignancy. The lungs and liver are the two common primary organs affected. Metastatic disease was reported in more than 100 cases in the literature. However, no firm conclusions can be determined for recommended treatment options. The current case presents a patient with metastatic pulmonary epithelioid hemangioendothelioma to the cervical and mediastinal lymph nodes, lungs and liver that has been treated with pazopanib for more than two years with PET avid complete metabolic response in the mediastinum and lungs, and long-lasting stable disease. Target therapies that block VEGFR have a logical base in this rare malignancy. The current case is the first to report objective, long-lasting response to pazopanib

Gut-directed hypnotherapy is considered to be an effective treatment in irritable bowel syndrome (IBS) but few studies report the long-term effects. This retrospective study aims to evaluate the long-term perceived efficacy of gut-directed hypnotherapy given outside highly specialized hypnotherapy centers. 208 patients, who all had received gut-directed hypnotherapy, were retrospectively evaluated. The Subjective Assessment Questionnaire (SAQ) was used to measure changes in IBS symptoms, and patients were classified as responders and non-responders. Patients were also asked to report changes in health-care seeking, use of drugs for IBS symptoms, use of alternative non-pharmacological treatments, and if they still actively used hypnotherapy. Immediately after hypnotherapy, 103 of 208 patients (49%) were responders and 75 of these (73%) had improved further at the follow-up 2-7 years after hypnotherapy (mean 4 years). A majority of the responders still used hypnotherapy on a regular basis at follow-up (73%), and the responders reported a greater reduction in health-care seeking than non-responders. A total of 87% of all patients reported that they considered gut-directed hypnotherapy to be worthwhile, and this differed between responders and non-responders (100% vs. 74%; p hypnotherapy in refractory IBS is an effective treatment option with long-lasting effects, also when given outside highly specialized hypnotherapy centers. Apart from the clinical benefits, the reduction in health-care utilization has the potential to reduce the health-care costs.

Medulloblastoma in childhood: long-term results of treatment

1981-01-01

Thirty-one children under the age of 15 years with verified medulloblastoma were treated at Addenbrookes Hospital from 1940 to 1976. In addition to surgical treatment, all received high dose irradiation to the whole neuraxis. Nine were still alive in 1979, of whom eight were examined. All these patients showed some residual problems, but five were leading active lives and had only minor physical disability. There was evidence of disturbance in growth, with shortening of the spine in relation to the limbs, in all the children. The height centile was lower than expected from parental height in four and one was severely dwarfed. Growth hormone secretion in response to exercise was, however, normal in five of six patients tested. Three children also showed failure of growth of the jaw sufficiently severe to be a cosmetic problem. Frank mental retardation was present in three children. A raised resting TSH level was found in two children, one of whom had a multinodular goiter. Of the three children with severe problems, two had been treated when under two years of age. Long-term follow-up of children who survive medulloblastoma is clearly necessary and consideration should perhaps be given to revision of current treatment regimes in very young children

To add to the data for long-term reverse pull headgear (RPHG) outcomes and further explore possible variables that could be predictors of long-term failure. Cephalometric radiographs of 41 Class III malocclusion children treated with RPHG (face mask) were evaluated before and immediately after treatment; at 5 years posttreatment; and, for 18 patients, at 10 years posttreatment. Patients were assigned to success or failure groups according to positive or negative overjet at the longest available recall. Seventy-five percent of the patients maintained positive overjet, whereas 25% outgrew the correction. In a stepwise discriminant analysis, a large mandible and vertical positioning of the maxilla and mandible so that mandibular growth would be projected more horizontally were the major indicators of unfavorable later mandibular growth. Patients who experienced downward-backward rotation of the mandible during RPHG treatment were more likely to be categorized in the failure group. The age at which treatment began had no effect on long-term success and failure for patients younger than 10 years, but the percentage of successful treatment decreased after that age. When RPHG treatment is used for all but the most obviously prognathic children to correct anterior cross-bite in the early mixed dentition, positive overjet is maintained long-term in 70%-75% of cases, whereas 25%-30% of cases relapse into reverse overjet mainly because of increased horizontally directed and often late mandibular growth. Up to age 10, the time at which RPHG treatment began does not appear to be a major factor in long-term success in maintaining positive overjet.

In this paper, we will present results of plasma treatments of meristematic cells of Daucus carota. Plasma needle was used as an atmospheric pressure/gas composition source of non-equilibrium plasma in all treatments. Activity of antioxidant enzymes superoxide dismutase and catalase was measured immediately after plasma treatment and after two weeks following the treatment. Superoxide dismutase activity was increased in samples immediately after the plasma treatment. On the other hand, catalase activity was much higher in treated samples when measured two weeks after plasma treatment. These results show that there is a direct proof of the triggering of signal transduction in the cells by two reactive oxygen species H2O2 and O2-, causing enzyme activity and short and long term effects even during the growth of calli, where the information is passed to newborn cells over the period of two weeks.

of a final repository site, the built-up of additional volume has to be considered as very critical. Moreover, corrosive effects on cemented drums during long-term interim storage at the surface have raised doubts about the long-term stability of such waste products. In order to avoid such disadvantages solidification methods have been improved in order to get a well-defined product with a better load factor of wastes in the matrix. In a complete different approach, other technologies solidify the liquid radioactive wastes without adding of any inactive material by means of drying. Different installations are available for spent resin or concentrate drying. Such methods produce suitable waste products for final disposal and achieve additional volume reduction factors for final disposal. On the other hand, design of the treatment plant as well as the subsequent drum handling and interim storage plants have to consider the high concentration of radioactivity in the final waste product and have to deal with appropriate packages, remote controlled operations and shielding. The presentation will briefly introduce examples for the mentioned treatment options and report on results achieved with it in nuclear installations with WH (Westinghouse)/ HANSA (Hansa Projekt Anlagentechnik GmbH) technologies. Further on, the paper will discuss the evaluation of the advantages and disadvantages of the treatment options relative to the characteristics of the wastes and the environment to be considered (availability of repository, existing or assumed repository, acceptance criteria etc.). In conclusion such self assessment regarding priorities, background and goals is essential for the selection of a suitable approach. - The industry can address the various specific needs with proven technologies and services; - Westinghouse/ Hansa Projekt Anlagentechnik have served various customers around the globe under different regulatory environment with successful equipment deliveries and

125 I emits very low energy conversion and Auger electrons. This radionuclide has been used in place of 131 I with the hope of reducing the incidence of post treatment hypothyroidism. 303 of 360 patients treated have been reviewed. Originally very large doses of 125 I were prescribed (751-1,600 μCi/g) but 9 out of 15 patients (60%) became hypothyroid, therefore 4 smaller therapeutic regimes were employed. (1) 55 patients received doses of 200 μCi or less/g thyroid, 69% are euthyroid and 24% hypothyroid after an average of 33 months from treatment. (2) 87 patients received doses of 201-350 μCi/g thyroid, 67% are euthyroid and 21% hypothyroid after an average follow up of 30 months. (3) 70 patients received doses of 351-500 μCi/g thyroid, 77% are euthyroid and 18% hypothyroid 36 months after treatment and (4) 76 patients received doses of 501-750 μCi/g, 41% are euthyroid and 56% hypothyroid 49 months after therapy. No long term complications such as thyroid cancer or leukaemia have occurred but because 125 I does not eliminate or reduce the incidence of post treatment hypothyroidism it probably should not be used in preference to 131 I for the routine treatment of hyperthyroidism

Nail Psoriasis: A Review of Treatment Options.

2016-04-01

Nail involvement affects 80-90 % of patients with plaque psoriasis, and is even more prevalent in patients with psoriatic arthritis. This review is the result of a systemic approach to the literature and covers topical, intralesional, conventional systemic, and biologic systemic treatments, as well as non-pharmacological treatment options for nail psoriasis. The available evidence suggests that all anti-tumor necrosis factor-α, anti-interleukin (IL)-17, and anti-IL-12/23 antibodies which are available for plaque psoriasis and psoriatic arthritis are highly effective treatments for nail psoriasis. Conventional systemic treatments, including methotrexate, cyclosporine, acitretin, and apremilast, as well as intralesional corticosteroids, can also be effective treatments for nail psoriasis. Topical treatments, including corticosteroids, calcipotriol, tacrolimus, and tazarotene, have also been shown to have a position in the treatment of nail psoriasis, particularly in mild cases. Finally, non-pharmacological treatment options, including phototherapy, photodynamic therapy, laser therapy, and several radiotherapeutic options, are also reviewed but cannot be advised as first-line treatment options. Another conclusion of this review is that the lack of a reliable core set of outcomes measures for trials in nail psoriasis hinders the interpretation of results, and is urgently needed.

Long-term benzodiazepine treatment in patients with psychotic disorders attending a mental health service in rural Greece

Directory of Open Access Journals (Sweden)

Vaios Peritogiannis

2016-01-01

Full Text Available Introduction: Long-term benzodiazepine (BZD treatment in patients with mental disorders is widespread in clinical practice, and this is also the case of patients with schizophrenia, although the evidence is weak and BZD prescription is discouraged by guidelines and medical authorities. Data on BZD prescription are usually derived from national or regional databases whereas information on the use of BZD by patients with schizophrenia and related psychoses in general population-based samples is limited. Materials and Methods: Information for 77 patients with psychotic disorders who were regularly attending follow-up appointments with the multidisciplinary Mobile Mental Health Unit of the prefectures of Ioannina and Thesprotia, Northwest Greece, during 1-year period (2015 was obtained from our database. Results: From the total of 77 engaged patients, 30 (39% were regularly prescribed BZDs in the long term, as part of their treatment regimen. Prescribed BZDs were mostly diazepam and lorazepam, in 43.3% of cases each. The mean daily dose of these compounds was 13 mg and 3.77 mg, respectively. Statistical analysis showed a correlation of long-term BZD use with the history of alcohol/substance abuse. Most patients were receiving BZD continuously for several years, and the mean dose was steady within this interval. Conclusions: A large proportion of patients with psychotic disorders were regularly prescribed BZD in long term. It appears that when BZDs are prescribed for some period in the course of a psychotic disorder, their use commonly exceeds the recommended interval and then becomes a regular part of the chronic treatment regimen. Future research should address the factors that may be related to the long-term BZD use by patients with psychotic disorders. Interventions for the reduction of regular BZD prescription should target the primary care setting and all those who treat first episode patients.

This paper presents a new model for the valuation of European options, in which the volatility of returns consists of two components. One of these components is a long-run component, and it can be modeled as fully persistent. The other component is short-run and has a zero mean. Our model can...... be viewed as an affine version of Engle and Lee (1999), allowing for easy valuation of European options. The model substantially outperforms a benchmark single-component volatility model that is well-established in the literature, and it fits options better than a model that combines conditional...... model long-maturity and short-maturity options....

Long-term outcomes of treatment of hyperthyroidism in Ireland.

2012-02-03

We investigated the long-term outcome of treatment in 159 patients with hyperthyroidism first seen between 1979 and 1992. Median duration of follow-up was 10 1\\/2 years. We also inquired into current practice for the follow-up of hyperthyroidism by other endocrinologists in Ireland. Seven cases of unrecognised hyperthyroidism (4 per cent) and one of unrecognised hypothyroidism were identified. Among patients with Graves\\' disease, of those treated with an antithyroid drug, 28 per cent were in remission, 68 per cent had relapsed and 4 per cent had become hypothyroid. Of those treated by sub-total thyroidectomy, 31 per cent were in remission, 19 per cent had relapsed, 19 per cent were hypothyroid and 31 per cent were sub-clinically hypothyroid. Among patients treated with radioiodine, 19 per cent were euthyroid, 3 per cent were still hyperthyroid and three-quarters had become hypothyroid. In contrast, after radioiodine for toxic nodular goitre, 63 per cent were euthyroid and only 32 per cent had become hypothyroid (Chi Squared v. Graves\\' disease, P = 0.001). Of 73 patients receiving thyroxine replacement, plasma TSH was normal in only 41 per cent, although 82 per cent of patients had been seen by the family doctor within the previous 12 months. Seven of 17 other endocrinologists undertook long-term follow-up of hyperthyroid patients in their specialist clinics but none was using a computerised system to co-ordinate this. The findings confirm that careful follow-up is required for all hyperthyroid patients. The family doctor is well positioned to undertake this, but education and auditing are required.

Spent Fuel Long Term Interim Storage: The Spanish Policy

International Nuclear Information System (INIS)

Fernandez-Lopez, Javier

2014-01-01

ENRESA is the Spanish organization responsible for long-term management of all categories of radioactive waste and nuclear spent fuel and for decommissioning nuclear installations. It is also in charge of the management of the funds collected from waste producers and electricity consumers. The national policy about radioactive waste management is established at the General Radioactive Waste Plan by the Government upon proposal of the Ministry of Industry, Energy and Tourism. Now the Plan in force is the Sixth Plan approved in 2006. The policy on spent nuclear fuel, after description of the current available options, is set up as a long term interim storage at a Centralized Temporary Storage facility (CTS, or ATC in Spanish acronym) followed by geologic disposal, pending technological development on other options being eligible in the future. After a site selection process launched in 2009, the site for the ATC has been chosen at the end of 2011. The first steps for the implementation of the facility are described in the present paper.

Long-term lithium treatment increases intracellular and extracellular brain-derived neurotrophic factor (BDNF) in cortical and hippocampal neurons at subtherapeutic concentrations.

Science.gov (United States)

De-Paula, Vanessa J; Gattaz, Wagner F; Forlenza, Orestes V

2016-12-01

The putative neuroprotective effects of lithium treatment rely on the fact that it modulates several homeostatic mechanisms involved in the neurotrophic response, autophagy, oxidative stress, inflammation, and mitochondrial function. Lithium is a well-established therapeutic option for the acute and long-term management of bipolar disorder and major depression. The aim of this study was to evaluate the effects of subtherapeutic and therapeutic concentrations of chronic lithium treatment on brain-derived neurotrophic factor (BDNF) synthesis and secretion. Primary cultures of cortical and hippocampal neurons were treated with different subtherapeutic (0.02 and 0.2 mM) and therapeutic (2 mM) concentrations of chronic lithium treatment in cortical and hippocampal cell culture. Lithium treatment increased the intracellular protein expression of cortical neurons (10% at 0.02 mM) and hippocampal neurons (28% and 14% at 0.02 mM and 0.2 mM, respectively). Extracellular BDNF of cortical neurons increased 30% and 428% at 0.02 and 0.2 mM, respectively and in hippocampal neurons increased 44% at 0.02 mM. The present study indicates that chronic, low-dose lithium treatment up-regulates BDNF production in primary neuronal cell culture. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Longer survival for children with sarcoma has led to the recognition of chronic health conditions related to prior therapy. We sought to study the association of sarcoma therapy with the development of scoliosis. We reviewed patient demographics, treatment exposures, and functional outcomes for patients surviving >10 years after treatment for sarcoma between 1964 and 2002 at our institution. The diagnosis of scoliosis was determined by imaging. Functional performance and standardized questionnaires were completed in a long-term follow-up clinic. We identified 367 patients, with median age at follow-up of 33.1 years. Scoliosis was identified in 100 (27.2%) patients. Chest radiation (relative risk (RR), 1.88 (95% confidence interval (CI), 1.21-2.92), p sarcoma are at risk of developing scoliosis when treatment regimens include chest radiation or rib resection. Identification of these risk factors may allow for early intervention designed to prevent adverse long-term outcomes. Cancer survivors at risk of developing scoliosis may benefit from monitoring of pulmonary status and early physical therapy.

The objective of this study was to evaluate the gain in final height of achondroplasia (ACH) patients with long-term growth hormone (GH) treatment. We analyzed medical data of 22 adult patients (8 males and 14 females) treated with GH at a dose of 0.05 mg/kg/day. Optionally, tibial lengthening (TL) was performed with the Ilizalov method in 15 patients and TL as well as femoral lengthening (FL) in 6 patients. Concomitant gonadal suppression therapy with buserelin acetate was applied in 13 patients. The mean treatment periods with GH were 10.7 ± 4.0 and 9.3 ± 2.5 years for males and females, respectively. GH treatment augmented the final height +0.60 ± 0.52 SD (+3.5 cm) and +0.51 ± 1.29 SD (+2.8 cm) in males and females compared to non-treated ACH patients, respectively. Final height of ACH patients that underwent GH and TL increased +1.72 ± 0.72 SD (+10.0 cm) and +1.95 ± 1.34 SD (+9.8 cm) in males and females, respectively. GH, TL, and FL increased their final height +2.97 SD (+17.2 cm) and +3.41 ± 1.63 SD (+17.3 cm) in males and females, respectively. Gonadal suppression therapy had no impact on final height. Long-term GH treatment contributes to 2.6 and 2.1% of final adult height in male and female ACH patients, respectively.

Long-term follow-up of low-dose external pituitary irradiation for Cushing's disease

International Nuclear Information System (INIS)

Littley, M.D.; Shalet, S.M.; Beardwell, C.G.; Ahmed, S.R.; Sutton, M.L.

1990-01-01

Twenty-four patients (three male) with Cushing's disease, aged between 11 and 67 years, were treated with low-dose external pituitary irradiation (20 Gy in eight fractions over 10-12 days) and followed for between 13 and 171 months (median 93 months). Eleven patients (46%) went into remission 4-36 months after irradiation, but five subsequently relapsed. In this series, the low incidence of radiation-induced hypopituitarism and absence of other complications attributable to radiotherapy suggest that low-dose pituitary irradiation may be a useful treatment option in selected patients. However, long-term follow-up has demonstrated a high relapse rate and failure to prevent Nelson's syndrome in adrenalectomized patients, indicating that it should not be used as primary treatment in preference to selective adenomectomy.

The treatment for pediatric craniopharyngioma remains challenging and controversial. Although this tumor is histologically benign, the treatments include radical surgery, conservative surgery, radiotherapy, intracystic chemotherapy and multimodality approaches. In addition, the long-term functional outcomes including visual function, endocrine function, cognitive function, hypothalamic function, and quality of life are complex and major problems among survivors. In this paper, we reviewed the recent treatments for pediatric craniopharyngioma and the long-term outcomes after treatment in literatures. (author)

Long-term efficacy and safety of ramosetron in the treatment of diarrhea-predominant irritable bowel syndrome

Full Text Available Toshimi Chiba, Kazunari Yamamoto, Shoko Sato, Kazuyuki Suzuki Division of Gastroenterology and Hepatology, Department of Internal Medicine, School of Medicine, Iwate Medical University, Morioka, Iwate, Japan Abstract: Irritable bowel syndrome (IBS is a functional disease with persisting gastrointestinal symptoms that has been classified into four subtypes. Serotonin (5-hydroxytryptamine [5-HT] plays important physiological roles in the contraction and relaxation of smooth muscle. Intraluminal distension of the intestine is known to stimulate the release of endogenous 5-HT from enterochromaffin cells, activating 5-HT3 receptors located on primary afferent neurons and leading to increases in intestinal secretions and peristaltic activity. Ramosetron, a potent and selective 5-HT3-receptor antagonist, has been in development for use in patients suffering from diarrhea-predominant IBS. In a double-blind, placebo-controlled, parallel-group study of 418 patients with diarrhea-predominant IBS-D, once-daily 5 µg and 10 µg doses of ramosetron increased the monthly responder rates of IBS symptoms compared to placebo. In a 12-week randomized controlled trial of 539 patients, a positive response to treatment was reported by 47% of a once-daily 5 µg dose of ramosetron-treated individuals compared to 27% of patients receiving placebo (P<0.001. Furthermore, the responder rate was increased in the oral administration of 5 µg of ramosetron for at least 28 weeks (up to 52 weeks, and long-term efficacy for overall improvement of IBS symptoms was also demonstrated. The rate was further increased subsequently. Adverse events were reported by 7% in ramosetron treatment. No serious adverse events, eg, severe constipation or ischemic colitis, were reported for long-term treatment with ramosetron. In conclusion, further studies to evaluate the long-term efficacy and safety of ramosetron are warranted in the form of randomized controlled trials. Keywords: long-term

Sun, Linlin; Chen, Dongping; Zhao, Xuezhi; Xu, Chenggang; Mei, Changlin

2010-01-01

Prolonged steroid therapy is generally used for steroid-dependent nephrotic syndrome in pediatric patients. However, dwarfism secondary to a long-term regimen and its successful reverse is rarely reported. The underlying mechanism of dwarfism is still poorly understood, as both long-term steroid use and nephrotic syndrome may interact or independently interfere with the process of growth. Here, we present a 17-year-old patient with dwarfism and steroid-dependent nephrotic syndrome and the successful treatment by recombinant human growth factor and cyclosporine A with withdrawal of steroid. We also briefly review the current understanding and the management of dwarfism in pediatric patients with nephrotic syndrome.

Nonsurgical treatments, such as sclerotherapy have been attempted for head and neck lymphagiomas. Of the available sclerosing agents, picibanil has shown satisfactory short-term treatment results in many studies, but no study has presented long-term treatment results. Accordingly, in the present study, the authors retrospectively reviewed the long-term treatment results of picibanil sclerotherapy. Fifty-five lymphangioma patients who underwent picibanil sclerotherapy were enrolled. Data about initial and long-term response, recurrence, and excision rate were collected. Initial response rates were 83.5 percent and long-term response rates were 76.3 percent. Initial and the long-term response rate were equally good for lymphangioma.

Periodontal maintenance (PM) is a critical factor in the long-term success of both periodontal and dental implant therapy. Studies have shown both modern periodontal and dental implant therapies are effective in maintaining natural teeth and replacing lost teeth, respectively. However, without a regular program of clinical reevaluation, plaque control, oral hygiene instruction, and reassessment of biomechanical factors, the benefits of treatment often are lost and inflammatory disease in the form of recurrent periodontitis or periimplantitis may result. This article reviews the goals, types, and appropriate frequency of PM in periodontal and dental implant therapy, as well as the incidence and etiology of periimplant disease and strategies for management when recurrent disease develops during the maintenance phase of treatment.

Long-term use of short- and long-acting nitrates in stable angina pectoris.

Science.gov (United States)

Kosmicki, Marek Antoni

2009-05-01

Long-acting nitrates are effective antianginal drugs during initial treatment. However, their therapeutic value is compromised by the rapid development of tolerance during sustained therapy, which means that their clinical efficacy is decreased during long-term use. Sublingual nitroglycerin (NTG), a short-acting nitrate, is suitable for the immediate relief of angina. In patients with stable angina treated with oral long-acting nitrates, NTG maintains its full anti-ischemic effect both after initial oral ingestion and after intermittent long-term oral administration. However, NTG attenuates this effect during continuous treatment, when tolerance to oral nitrates occurs, and this is called cross-tolerance. In stable angina long-acting nitrates are considered third-line therapy because a nitrate-free interval is required to avoid the development of tolerance. Nitrates vary in their potential to induce the development of tolerance. During long-lasting nitrate therapy, except pentaerythritol tetranitrate (PETN), one can observe the development of reactive oxygen species (ROS) inside the muscular cell of a vessel wall, and these bind with nitric oxide (NO). This leads to decreased NO activity, thus, nitrate tolerance. PETN has no tendency to form ROS, and therefore during long-term PETN therapy, there is probably no tolerance or cross-tolerance, as during treatment with other nitrates.

Tyrosine kinase inhibitors represent today's treatment of choice in chronic myeloid leukemia (CML). Allogeneic hematopoietic stem cell transplantation (HSCT) is regarded as salvage therapy. This prospective randomized CML-study IIIA recruited 669 patients with newly diagnosed CML between July 1997 and January 2004 from 143 centers. Of these, 427 patients were considered eligible for HSCT and were randomized by availability of a matched family donor between primary HSCT (group A; N=166 patients) and best available drug treatment (group B; N=261). Primary end point was long-term survival. Survival probabilities were not different between groups A and B (10-year survival: 0.76 (95% confidence interval (CI): 0.69-0.82) vs 0.69 (95% CI: 0.61-0.76)), but influenced by disease and transplant risk. Patients with a low transplant risk showed superior survival compared with patients with high- (Ptreatment (56% vs 6%; P<0.001). Differences in symptoms and Karnofsky score were not significant. In the era of tyrosine kinase inhibitors, HSCT remains a valid option when both disease and transplant risk are considered.

Within the framework of nuclear waste management studies, the 'ose-composent' concept is considered to be an attractive option for the long-term perspective. This paper proposes a new system called TASSE ('Thorium-based Accelerator-drives System with Simplified fuel cycle for long-term Energy production') destined for the current French park renewal. The main idea of the TASSE concept is to simplify both the front end and the back end of the fuel cycle. Its major goal is to provide electricity with low waste production and economical competitiveness. (author)

Solidification of radioactive liquid wastes. A comparison of treatment options for spent resins and concentrates

Roth, A.; Willmann, F.; Ebata, M.; Wendt, S.

Ion exchange is one of the most common and effective treatment methods for liquid radioactive waste. However, spent ion exchange resins are considered to be problematic waste that in many cases require special approaches and pre-conditioning during its immobilization to meet the acceptance criteria for disposal. Because of the function that they fulfill, spent ion exchange resins often contain high concentrations of radioactivity and pose special handling and treatment problems. Another very common method of liquid radioactive waste treatment and water cleaning is the evaporation or diaphragm filtration. Both treatment options offer a high volume reduction of the total volume of liquids treated but generate concentrates which contain high concentrations of radioactivity. Both mentioned waste streams, spent resins as well as concentrates, resulting from first step liquid radioactive waste treatment systems have to be conditioned in a suitable manner to achieve stable waste products for final disposal. The most common method of treatment of such waste streams is the solidification in a solid matrix with additional inactive material like cement, polymer etc. In the past good results have been achieved and the high concentration of radioactivity can be reduced by adding the inactive material. On the other hand, under the environment of limited space for interim storage and the absence of a final repository site, the built-up of additional volume has to be considered as very critical. Moreover, corrosive effects on cemented drums during long-term interim storage at the surface have raised doubts about the long-term stability of such waste products. In order to avoid such disadvantages solidification methods have been improved in order to get a well-defined product with a better load factor of wastes in the matrix. In a complete different approach, other technologies solidify the liquid radioactive wastes without adding of any inactive material by means of drying

Chronic diseases afflict patients for many years, often to the end of life, and there is increasing need for estimating lifelong risk and for evaluating the effects of treatment in the long term. Yet recommendations for lifelong treatment are most frequently based on findings from randomized clinical trials lasting only a few years. There is therefore a clear need for much longer term data, and here we present the advantages and disadvantages of many strategies, including the use of long-term posttrial follow-up, of long-term prospective cohort studies, registry databases, and of administrative databases. We also emphasize the need for long-term cost-effectiveness studies. One of the most promising strategies comes from linkage of data gathered through the ever-expanding pool of administrative databases worldwide with data from other sources, including randomized trials and the many forms of observational study.

Objective To conduct a preliminary examination of long-term outcomes on a broad range of affective disorder symptoms treated with a newly developed intervention: The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP). Method Maintenance of treatment gains at long-term follow-up (LTFU) were explored in patients (n = 15, mean age = 32.27; 60% female) who completed a clinical trial of the UP. Results Treatment gains observed at 6-month follow-up (6MFU) on measures of clinical severity, general symptoms of depression and anxiety, and a measure of symptom interference in daily functioning were largely maintained 12 months later (at an average of 18 months posttreatment), and any significant changes from 6MFU to LTFU reflected small increases in symptoms that remained, on average, in the subclinical range. Conclusions These findings provide the first initial support for the durability of broad treatment gains following transdiagnostic treatment. PMID:25113056

Evaluation of the pharmacoeconomics of drugs used for the treatment of long-term complications of sulfur mustard

Directory of Open Access Journals (Sweden)

Yunes Panahi

2016-08-01

Full Text Available Sulfur Mustard (SM, a cytotoxic vesicant chemical warfare agent, has powerful irritant and blistering effects on the skin, eyes and respiratory tract. Since during the Iraq-Iran war, many Iranian soldiers and civilians were exposed to SM, there are several victims still suffering from long-term cutaneous, ocular and pulmonary complications. Currently, there is no definite treatment for long-term complications of SM, and only supportive medical care is being taken to minimize the symptoms. In this study, we compared the cost-effectiveness of common drugs that are used against long-term SM-induced complications in Iranian patients. In this review article, electronic databases were checked using the following key words: sulfur mustard, lung, skin, eye, cost-effectiveness, pharmacoeconomics and treatment. Abstracts of non-English papers and proceedings of congresses on SM were also assessed. Among the studied drugs, high-dose oral N-acetyl cysteine and long-acting inhaled corticosteroids against respiratory complications, topical corticosteroids and oral antihistamines against cutaneous complications and non-steroidal anti-inflammatory drugs and corticosteroids ophthalmic drops against ocular complications were found to be cost-effective. Usage of different drugs in the treatment of SM injuries in Iran, have imposed a significant economic burden to patients and their families because many drugs that are effective against chemical injuries are not covered by insurance. In addition, the development of more effective drugs in this field is considered as an urgent demand that should be noticed by the pharmaceutical industry.

Introduction: Recent literature revealed good short-term results after microfracturing (MFX) of isolated focal cartilage defects in the knee joint. Study purpose was a long-term evaluation of patients who received MFX through a multimodal approach, correlating clinical scores and morphological pre- and postoperative MRI-scans. Materials and methods: Between 2000 and 2007 158 patients were treated with MFX for focal femoral or tibial defects at our department. Patients with instabilities, secondary surgical intervention, patellofemoral lesions, a plica mediopatellaris or more than one cartilage defect site and age >55 were excluded. 15 patients were included. Minimum postoperative follow-up (FU) was 18 months (18–78 m). Mean age at surgery was 45 years (27–54), mean FU-interval 48 months (18–78 m). Male to female ratio was 9:6. For clinical assessment the Knee Osteoarthritis Outcome Score (KOOS) and Lysholm Score were used, radiological evaluation was performed with radiographs and 3Tesla-MRI. Results: Clinical knee function was rated good to excellent in 1 patient, fair in 2 and poor in 10 patients. 2/15 patients received full knee replacement due to insufficient cartilage repair through MFX during FU period. Evaluation of pre- and postoperative MRI showed good cartilage repair tissue in 1 (7.7%), moderate repair in 2 (15.4%) and poor fill in 10 patients (76.9%). In these 10 patients the defect size increased. Average defect size preoperatively was 187 mm 2 (range 12–800 mm 2 ) and postoperatively 294 mm 2 (40–800 mm 2 ). The KOOS-Pain averaged 60 (39–94), KOOS-Symptoms 60.6 (21–100), KOOS-ADL 69 (21–91), KOOS-Sports 35.7 (5–60) and KOOS-QUL 37.2 (6–81). The average Lysholm Score was 73.9 (58–94). 10 patients showed a varus leg axis deviation (Ø 5.9°), 3 had a neutral alignment. The alignment correlated positively with KOOS and especially with the Lysholm Score. Conclusion: Our study demonstrated that MFX as a treatment option for cartilage

Long-Term Treatment with Paroxetine Increases Verbal Declarative Memory and Hippocampal Volume in Posttraumatic Stress Disorder

Science.gov (United States)

Vermetten, Eric; Vythilingam, Meena; Southwick, Steven M.; Charney, Dennis S.; Bremner, J. Douglas

2011-01-01

Background Animal studies have shown that stress is associated with damage to the hippocampus, inhibition of neurogenesis, and deficits in hippocampal-based memory dysfunction. Studies in patients with posttraumatic stress disorder (PTSD) found deficits in hippocampal-based declarative verbal memory and smaller hippocampal volume, as measured with magnetic resonance imaging (MRI). Recent preclinical evidence has shown that selective serotonin reuptake inhibitors promote neurogenesis and reverse the effects of stress on hippocampal atrophy. This study assessed the effects of long-term treatment with paroxetine on hippocampal volume and declarative memory performance in PTSD. Methods Declarative memory was assessed with the Wechsler Memory Scale–Revised and Selective Reminding Test before and after 9–12 months of treatment with paroxetine in PTSD. Hippocampal volume was measured with MRI. Of the 28 patients who started the protocol, 23 completed the full course of treatment and neuropsychological testing. Twenty patients were able to complete MRI imaging. Results Patients with PTSD showed a significant improvement in PTSD symptoms with treatment. Treatment resulted in significant improvements in verbal declarative memory and a 4.6% increase in mean hippocampal volume. Conclusions These findings suggest that long-term treatment with paroxetine is associated with improvement of verbal declarative memory deficits and an increase in hippocampal volume in PTSD.

The requirement for enhanced CREB1 expression in consolidation of long-term synaptic facilitation and long-term excitability in sensory neurons of Aplysia

Science.gov (United States)

Liu, Rong-Yu; Cleary, Leonard J.; Byrne, John H.

2011-01-01

Accumulating evidence suggests that the transcriptional activator CREB1 is important for serotonin (5-HT)-induced long-term facilitation (LTF) of the sensorimotor synapse in Aplysia. Moreover, creb1 is among the genes activated by CREB1, suggesting a role for this protein beyond the induction phase of LTF. The time course of the requirement for CREB1 synthesis in the consolidation of long-term facilitation was examined using RNA interference (RNAi) techniques in sensorimotor co-cultures. Injection of CREB1 small-interfering RNA (siRNA) immediately or 10 h after 5-HT treatment blocked LTF when measured at 24 h and 48 h after treatment. In contrast, CREB1 siRNA did not block LTF when injected 16 h after 5-HT treatment. These results demonstrate that creb1 expression must be sustained for a relatively long time in order to support the consolidation of LTF. In addition, LTF is also accompanied by a long-term increase in the excitability (LTE) of sensory neurons (SNs). Because LTE was observed in the isolated SN after 5-HT treatment, this long-term change was intrinsic to that element of the circuit. LTE was blocked when CREB1 siRNA was injected into isolated SNs immediately after 5-HT treatment. These data suggest that 5-HT-induced CREB1 synthesis is required for consolidation of both LTF and LTE. PMID:21543617

In France, waste management, a sensitive issue in term of public opinion, is developing quickly, and due to twenty years of experience, is now reaching maturity. With the launching of the French nuclear programme, the use of radioactive sources in radiotherapy and industry, waste management has become an industrial activity. Waste management is an integrated system dealing with the wastes from their production to the long term disposal, including their identification, sortage, treatment, packaging, collection and transport. This system aims at guaranteing the protection of present and future populations with an available technology. In regard to their long term management, and the design of disposals, radioactive wastes are divided in three categories. This classification takes into account the different radioisotopes contained, their half life and their total activity. Presently short-lived wastes are stored in the shallowland disposal of the ''Centre de la Manche''. Set up within the French Atomic Energy Commission (CEA), the National Agency for waste management (ANDRA) is responsible within the framework of legislative and regulatory provisions for long term waste management in France [fr

Tennis elbow (TE) is one of the commonest myotendinosis. Different treatment options are available and autologous blood injection has emerged as the one of the acceptable modalities of treatment. Long term studies over a larger group of patients are however lacking. The purpose of this study was to evaluate these patients on longer durations. One-hundred and twenty patients of TE, who failed to respond to conventional treatment including local steroid injections were taken up for this prospective study over the period from year 2005 to 2011 and were followed up for the minimum of 3 years (range 3-9 years). Two mL of autologous blood was taken from the ipsilateral limb and injected into the lateral epicondyle. The effectiveness of the procedure was assessed by Pain Rating Sscale and Nirschl Staging, which was monitored before the procedure, at first week, monthly for first three months, at 6 months and then 3 monthly for first year, six monthly for next 2 years and then yearly. Statistical analysis was done and a P value of tennis elbow should be made as there is lot of controversy regarding the treatment.

Long-term storage of spent nuclear fuel

This report presents the results of a study on the storage of spent nuclear fuel, with particular reference to the options which would be available for long-term storage. Two reference programmes of nuclear power generation in the UK are defined and these are used as a basis for the projection of arisings of spent fuel and the storage capacity which might be needed. The characteristics of spent fuel which are relevant to long-term storage include the dimensions, materials and physical construction of the elements, their radioactive inventory and the associated decay heating as a function of time after removal from the reactor. Information on the behaviour of spent fuel in storage ponds is reviewed with particular reference to the corrosion of the cladding. The review indicates that, for long-term storage, both Magnox and AGR fuel would need to be packaged because of the high rate of cladding corrosion and the resulting radiological problems. The position on PWR fuel is less certain. Experience of dry storage is less extensive but it appears that the rate of corrosion of cladding is much lower than in water. Unit costs are discussed. Consideration is given to the radiological impact of fuel storage. (author)

The long-term patient in the era of community treatment.

Post hospital follow-up studies do not encompass the total population of long-term, psychiatrically disabled patients in the community, because a large proportion (in this study, 64%) have not had a recent hospitalization, either state or local. The authors identified a population of long-term, psychiatrically disabled patients in the community, all of whom carried functional psychotic diagnoses. Long-term disabled patients generally lead inactive lives, but in California seldom return to state hospitals. One third have been hospitalized locally within the past two years-younger patients much more than older patients. Almost half use private (Medicaid) outpatient services, but one fourth receive no mental health services at all. Less than a third live in board and care homes or cheap hotels; most live in nonsegregated, noninsitutional settings. The role of Supplemental Security Income (SSI) in enhancing adaptation of the chronically disabled was impressive to the research team.

Long-term energy planning with uncertain environmental performance metrics

Highlights: • Environmental performance uncertainty considered in a long-term energy planning model. • Application to electricity generation planning in British Columbia. • Interactions with climate change mitigation and adaptation strategy are assessed. • Performance risk-hedging impacts the technology investment strategy. • Sensitivity of results to model formulation is discussed. - Abstract: Environmental performance (EP) uncertainties span a number of energy technology options, and pose planning risk when the energy system is subject to environmental constraints. This paper presents two approaches to integrating EP uncertainty into the long-term energy planning framework. The methodologies consider stochastic EP metrics across multiple energy technology options, and produce a development strategy that hedges against the risk of exceeding environmental targets. Both methods are compared within a case study of emission-constrained electricity generation planning in British Columbia, Canada. The analysis provides important insight into model formulation and the interactions with concurrent environmental policy uncertainties. EP risk is found to be particularly important in situations where environmental constraints become increasingly stringent. Model results indicate allocation of a modest risk premium in these situations can provide valuable hedging against EP risk

The aim of this study was to investigate the long term effect of 131 I treatment on thyroid function and size in patients with non-toxic multinodular goitre. The subjects were 69 consecutive patients with multinodular non-toxic goitre selected for 131 I treatment and followed for a minimum of 12 months. Outcome measures were standard thyroid function variable and ultrasonically determined thyroid volume before and after treatment. Fifty-nine patients were treated with a single dose of 131 I, 12 with tow doses, and one with four doses. In 45 patients treated with one dose who remained euthyroid the median thyroid volume was reduced from 73 (interquartile range 50-106) ml to 29 (interquartile range 23-48) ml at 24 months. The median reuction was 40 (22-48) ml, half of which occurred within three months. Patients treated with two doses as well as those developing hypo- or hyper-thyroidism also had a significant reduction in thyroid volume. Eleven patients develeoped hypothyroidism (cumulative five year risk 22%). Side effects were few. In conclusion we find that 131 I treatment of multinodular non-toxic goitre is an attractive alternative to surgery. (au) (19 refs.)

Purpose: To review the impact of high–dose radiotherapy (RT) in the postprostatectomy salvage setting on long-term biochemical control and distant metastases–free survival, and to identify clinical and pathologic predictors of outcomes. Methods and Materials: During 1988–2007, 285 consecutive patients were treated with salvage RT (SRT) after radical prostatectomy. All patients were treated with either three-dimensional conformal RT or intensity-modulated RT. Two hundred seventy patients (95%) were treated to a dose ≥66 Gy, of whom 205 (72%) received doses ≥70 Gy. Eighty-seven patients (31%) received androgen-deprivation therapy as a component of their salvage treatment. All clinical and pathologic records were reviewed to identify treatment risk factors and response. Results: The median follow-up time after SRT was 60 months. Seven-year actuarial prostate-specific antigen (PSA) relapse-free survival and distant metastases–free survival were 37% and 77%, respectively. Independent predictors of biochemical recurrence were vascular invasion (p 0.4 ng/mL (p < 0.01), androgen-deprivation therapy (p = 0.03), Gleason score ≥7 (p = 0.02), and seminal vesicle involvement (p = 0.05). Salvage RT dose ≥70 Gy was not associated with improvement in biochemical control. A doubling time <3 months was the only independent predictor of metastatic disease (p < 0.01). There was a trend suggesting benefit of SRT dose ≥70 Gy in preventing clinical local failure in patients with radiographically visible local disease at time of SRT (7 years: 90% vs. 79.1%, p = 0.07). Conclusion: Salvage RT provides effective long-term biochemical control and freedom from metastasis in selected patients presenting with detectable PSA after prostatectomy. Androgen-deprivation therapy was associated with improvement in biochemical progression-free survival. Clinical local failures were rare but occurred most commonly in patients with greater burden of disease at time of SRT as reflected by

Liabilities identification and long-term management - Review of French situation

International Nuclear Information System (INIS)

2003-01-01

In France, long term liabilities due to nuclear activities concern four main operators: Electricite de France (EDF), AREVA (an industrial group created on September 3, 2001 and covering the entire fuel cycle from ore extraction and transformation to the recycling of spent fuel), the Atomic Energy Commission (CEA, the French public research organism in the nuclear sector) and the French Agency for radioactive waste management (ANDRA, in charge with the long term operation of radioactive waste installations). Long term liabilities are due to the financing of both decommissioning of nuclear installations and radioactive waste long term management. In the current French organisational scheme, the different operators must take the responsibility of these long term liabilities. The setting of national policies and the establishment of the legislation are carried out at a national level by the French state. These include the supervision of the three operators through different Ministries and the regulatory control of safety trough the Nuclear Safety Authority (ASN). EDF, AREVA, CEA and ANDRA are responsible for all aspects of the decommissioning (from a technical and financial point of view). Within a safety regulatory frame, they have their own initiative concerning future expenses, based on estimated costs and the expected operational lifetime of the installations. They are responsible of the definition and implementation of the technical options. Through its supervision activities, the French State regularly requires updating studies of these estimated costs, which are conducted by the operators. A general review of the management of these long-term liabilities is also carried out on a four years basis by the French Court of Accounts. Operators are due to constitute provisions during the life cycle of their installations. Provisions are calculated for each installation on the basis of the decommissioning expenses and of the reasonably estimated lifetime. They are re

Levelized cost-risk reduction prioritization of waste disposal options

The prioritization of solid waste disposal options in terms of reduced risk to workers, the public, and the environment has recently generated considerable governmental and public interest. In this paper we address the development of a methodology to establish priorities for waste disposal options, such as incineration, landfills, long-term storage, waste minimization, etc. The study is one result of an overall project to develop methodologies for Probabilistic Risk Assessments (PRAs) of non-reactor nuclear facilities for the US Department of Energy. Option preferences are based on a levelized cost-risk reduction analysis. Option rankings are developed as functions of disposal option cost and timing, relative long- and short-term risks, and possible accident scenarios. We examine the annual costs and risks for each option over a large number of years. Risk, in this paper, is defined in terms of annual fatalities (both prompt and long-term) and environmental restoration costs that might result from either an accidental release or long-term exposure to both plant workers and the public near the site or facility. We use event timing to weigh both costs and risks; near-term costs and risks are discounted less than future expenditures and fatalities. This technique levels the timing of cash flows and benefits by converting future costs and benefits to present value costs and benefits. We give an example Levelized Cost-Benefit Analysis of incinerator location options to demonstrate the methodology and required data

agent from controlled release systems of varied forms and applications. We manufactured prototype single- and double-layered matrix-type controlled release systems and tested their release patterns using numerical simulations and column experiments. In a series of simulations, we demonstrated that an encapsulated, dispersed-agent polymeric matrix-type controlled release system could deliver active agent at a predetermined constant rate for long time periods of years and decades. Such long-term, constant release system is useful in the construction of fertilizers, herbicides, or implantable drug delivery devices as well as in subsurface treatment. Construction of more advanced forms of controlled release systems is currently under way.

Even in the absence of evidence on its long-term efficacy and safety, a number of patients with venous thromboembolism (VTE) receive long-term therapy with fondaparinux alone in everyday practice. We used the Registro Informatizado de Enfermedad Tromboembólica (RIETE) registry to compare the rate of VTE recurrences and major bleeding at 10 and 90 days in patients with and without cancer. For long-term therapy, fondaparinux was compared with vitamin K antagonists (VKA) in patients without cancer and with low-molecular-weight heparin (LMWH) in those with cancer. Of 47,378 patients recruited, 46,513 were initially treated with heparin, 865 with fondaparinux. Then, 263 patients (78 with cancer) were treated for at least 3 months with fondaparinux. After propensity-score matching, there were no differences between patients receiving initial therapy with heparin or fondaparinux. Among patients with cancer, there were no differences between fondaparinux and LMWH. Among patients without cancer, the long-term use of fondaparinux was associated with an increased risk of major bleeding (3.24 % vs. 0.95 %, p<0.05). An unexpected high rate of major bleeding was observed in non-cancer patients treated with long-term fondaparinux. Our small sample does not allow to derive relevant conclusions on the use of fondaparinux in cancer patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

Ragweed-induced allergic rhinoconjunctivitis: current and emerging treatment options

Full Text Available Friedrich Ihler, Martin CanisDepartment of Otorhinolaryngology, University Medical Center Göttingen, Göttingen, GermanyAbstract: Ragweed (Ambrosia spp. is an annually flowering plant whose pollen bears high allergenic potential. Ragweed-induced allergic rhinoconjunctivitis has long been seen as a major immunologic condition in Northern America with high exposure and sensitization rates in the general population. The invasive occurrence of ragweed (A. artemisiifolia poses an increasing challenge to public health in Europe and Asia as well. Possible explanations for its worldwide spread are climate change and urbanization, as well as pollen transport over long distances by globalized traffic and winds. Due to the increasing disease burden worldwide, and to the lack of a current and comprehensive overview, this study aims to review the current and emerging treatment options for ragweed-induced rhinoconjunctivitis. Sound clinical evidence is present for the symptomatic treatment of ragweed-induced allergic rhinoconjunctivitis with oral third-generation H1-antihistamines and leukotriene antagonists. The topical application of glucocorticoids has also been efficient in randomized controlled clinical trials. Combined approaches employing multiple agents are common. The mainstay of causal treatment to date, especially in Northern America, is subcutaneous immunotherapy with the focus on the major allergen, Amb a 1. Beyond this, growing evidence from several geographical regions documents the benefit of sublingual immunotherapy. Future treatment options promise more specific symptomatic treatment and fewer side effects during causal therapy. Novel antihistamines for symptomatic treatment are aimed at the histamine H3-receptor. New adjuvants with toll-like receptor 4 activity or the application of the monoclonal anti-immunoglobulin E antibody, omalizumab, are supposed to enhance conventional immunotherapy. An approach targeting toll-like receptor 9 by

To evaluate the long-term follow-up results of percutaneous ethanol injection (PEI) for the treatment of hepatocellular carcinoma (HCC) in Korea. Sixty-eight nodular HCCs initially detected in 64 patients, were subjected to US-guided PEI as a first-line treatment. Long-term survival rates, local tumor progression rates, and complications were evaluated, as were the influences of tumor size and Child-Pugh class on these variables. No major complications occurred. The overall survival rates of the 64 patients at three and five years were 71% and 39%, and their cancer-free survival rates were 22% and 15%, respectively. The overall survival rate of patients with a small HCC (≤ 2 cm) was significantly higher (p = 0.014) than that of patients with a medium-sized HCC (≤ 2 cm). The overall survival rate of patients with Child- Pugh class A was significantly higher (p = 0.049) than that of patients with Child- Pugh class B. Of 59 cases with no residual tumor, local tumor progression was observed in ablation zones in 18, and this was not found to be significantly influenced by tumor size or Child-Pugh class. The results of our investigation of the long-term survival rates of PEI in HCC patients in Korea (a hepatitis B virus-endemic area) were consistent with those reported previously in hepatitis C endemic areas. Patients with a smaller tumor or a better liver function exhibited superior survival rates

Background: The skin tightening effects induced by non-insulated microneedle radiofrequency have proved long-lasting. Our previous three-dimensional volumetric assessment showed significant facial tightening for up to six months. However, nasal and peri-oral tightening effects lasted longer. The objective of this study was to investigate the distribution of the long-term volumetric reduction in facial area induced by a single fractional non-insulated microneedle radiofrequency treatment. Methods: Fifteen Asian patients underwent full facial skin tightening using a sharply tapered non-insulated microneedle radiofrequency applicator with a novel fractionated pulse mode. Three-dimensional volumetric assessments were performed at six and 12 months post-treatment. Patients rated their satisfaction using a 5-point scale at each follow up. Results: Objective assessments with superimposed three-dimensional color images showed significant volumetric reduction in the nasal and peri-oral areas at 12 months post-treatment in all patients. Median volumetric reductions at six and 12 months post-treatment were 13.1 and 12.3ml, respectively. All of the patients were satisfied with their results 12 months post-treatment. Side effects were not observed. Conclusions: This single fractional NIMNRF treatment provided long-lasting nasal and peri-oral tightening as shown via 3D volumetric assessment. Moreover, NIMNRF produced minimal complications, downtime, and few side effects. This approach provides safe and effective treatment of skin tightening.

Modelling the long-term deployment of electricity storage in the global energy system

International Nuclear Information System (INIS)

Despres, Jacques

2015-01-01

The current development of wind and solar power sources calls for an improvement of long-term energy models. Indeed, high shares of variable wind and solar productions have short- and long-term impacts on the power system, requiring the development of flexibility options: fast-reacting power plants, demand response, grid enhancement or electricity storage. Our first main contribution is the modelling of electricity storage and grid expansion in the POLES model (Prospective Outlook on Long-term Energy Systems). We set up new investment mechanisms, where storage development is based on several combined economic values. After categorising the long-term energy models and the power sector modelling tools in a common typology, we showed the need for a better integration of both approaches. Therefore, the second major contribution of our work is the yearly coupling of POLES to a short-term optimisation of the power sector operation, with the European Unit Commitment and Dispatch model (EUCAD). The two-way data exchange allows the long-term coherent scenarios of POLES to be directly backed by the short-term technical detail of EUCAD. Our results forecast a strong and rather quick development of the cheapest flexibility options: grid interconnections, pumped hydro storage and demand response programs, including electric vehicle charging optimisation and vehicle-to-grid storage. The more expensive battery storage presumably finds enough system value in the second half of the century. A sensitivity analysis shows that improving the fixed costs of batteries impacts more the investments than improving their efficiency. We also show the explicit dependency between storage and variable renewable energy sources. (author) [fr

Background Control of soil-transmitted helminth (STH) infections relies on the periodic and long-term administration of anthelmintic drugs to high-risk groups, particularly school-age children living in endemic areas. There is limited data on the effectiveness of long-term periodic anthelmintic treatment on the prevalence of STHs, particularly from operational programmes. The current study investigated the impact of 15 to 17 years of treatment with the broad-spectrum anthelmintic ivermectin, used for the control of onchocerciasis, on STH prevalence and intensity in school-age and pre-school children. Methods and Findings A cross-sectional study was conducted in communities that had received annual or twice-annual ivermectin treatments and geographically adjacent communities that had not received treatment in two districts of Esmeraldas Province in Ecuador. Stool samples were collected from school-age children and examined for STH infection using the Kato-Katz and formol-ether concentration methods. Samples were collected also from pre-school children and examined by the formol-ether concentration method. Data on risk factors for STH infection were collected by parental questionnaire. We sampled a total of 3,705 school-age children (6–16 years) from 31 treated and 27 non-treated communities, and 1,701 pre-school children aged 0–5 years from 18 treated and 18 non-treated communities. Among school-age children, ivermectin treatment had significant effects on the prevalence (adjusted OR =  0.06, 95% CI 0.03–0.14) and intensity of Trichuris trichiura infection (adjusted RR = 0.28, 95% CI 0.11–0.70), but appeared to have no impact on Ascaris lumbricoides or hookworm infection. Reduced prevalence and intensities of T. trichiura infection were observed among children not eligible to receive ivermectina, providing some evidence of reduced transmission of T. trichiura infection in communities receiving mass ivermectin treatments. Conclusion Annual and twice

Multiple sclerosis (MS) is an immune-mediated and neurodegenerative disease with an unpredictable outcome. Immune-modulatory treatment aims at decreasing long-term disability. With the increasing number of treatment options, it is essential to fully digest the possible side effects of the available therapeutics and to monitor patients is essential. Areas covered: All approved disease-modifying drugs (DMD) for MS are discussed in this review. Mode of action, adverse effects, reported risks for infections and malignancies, and pregnancy related issues are discussed in the review. The authors also provide suggestions for monitoring therapy. For all approved DMDs the pivotal studies have been included for possible side effects, as well as reports by health authorities. For this manuscript, PubMed was checked for reports on side effects for various drugs. Expert opinion: Treatment options in MS are manifold, each carrying different risks. The safety-risk profile for approved agents is favorable. Knowing and monitoring these possible side effects is essential to minimize risks associated with treatment. Presently, the long-term experience for some of these therapies is missing and this must be addressed.

Using QMRAcatch - a stochastic hydrological water quality and infection risk model - to identify sustainable management options for long term drinking water resource planning

River water resources in urban environments play a critical role in sustaining human health and ecosystem services, as they are used for drinking water production, bathing and irrigation. In this study the hydrological water quality model QMRAcatch was used combined with measured concentrations of human enterovirus and human-associated genetic fecal markers. The study area is located at a river/floodplain area along the Danube which is used for drinking water production by river bank filtration and further disinfection. QMRAcatch was previously developed to support long term planning of water resources in accordance with a public infection protection target (Schijven et al., 2015). Derx et al. 2016 previously used QMRAcatch for evaluating the microbiological quality and required virus-reduction targets at the study area for the current and robust future "crisis" scenarios, i.e. for the complete failure of wastewater treatment plants and infection outbreaks. In contrast, the aim of this study was to elaborate future scenarios based on projected climate and population changes in collaboration with urban water managers. The identified scenarios until 2050 include increased wastewater discharge rates due to the projected urban population growth and more frequent storm and overflow events of urban sewer systems following forecasted changes in climate and hydrology. Based on the simulation results for the developed scenarios sustainable requirements of the drinking water treatment system for virus reductions were re-evaluated to achieve the health risk target. The model outcomes are used to guide practical and scientifically sound management options for long term water resource planning. This paper was supported by FWF (Vienna Doctoral Program on Water Resource Systems W1219-N22) and the GWRS project (Vienna Water) as part of the "(New) Danube-Lower Lobau Network Project" funded by the Government of Austria and Vienna, and the European Agricultural Fund for Rural

Tourani, Saam S; Taylor, G Ian; Ashton, Mark W

2016-08-01

With advancements in technology and microsurgical techniques, lymphovenous anastomosis has become a popular reconstructive procedure in the treatment of chronic lymphedema. However, the long-term patency of these anastomoses is not clear in the literature. A systematic review of the MEDLINE and EMBASE databases was performed to assess the reported long-term patency of lymphovenous anastomoses. A total of eight studies satisfied the inclusion criteria. Pooled data from four similar experiments in normal dogs showed an average long-term (≥5 months) patency of 52 percent. The only experiment in dogs with chronic lymphedema failed to show any long-term patency. The creation of peripheral lymphovenous anastomoses with a moderate long-term patency rate has become technically possible. However, the long-term results in chronic lymphedema are limited.

The tyrosine kinase inhibitor Imatinib Mesylate has dramatically improved the clinical outcome of chronic myeloid leukemia (CML) patients in the chronic phase of the disease, generating unprecedented rates of complete hematologic and cytogenetic responses and sustained reductions in BCR-ABL transcripts. Here, we present an overview on the efficacy and safety of Imatinib and describe the most important clinical studies employing this drug for the frontline treatment of chronic phase CML. We also discuss recent reports describing the long-term outcome of patients receiving Imatinib for their disease. The imminent availability of generic forms of Imatinib coupled with the approval of expensive second-generation tyrosine kinase inhibitors underlines an unmet need for early molecular parameters that may distinguish CML patients likely to benefit from the drug from those that should receive alternative forms of treatment.

Iron deficiency (ID), with or without anemia, is highly prevalent worldwide and has clinical consequences. The prevention and treatment of ID is a major public health goal. Accurate diagnosis, selection of the appropriate iron replacement therapy and addressing the underlying cause, remain as the main challenges in ID management. Areas covered: This review aims to provide a narrative review of current available evidence on iron supplementation options regularly used to treat ID, including oral and intravenous (IV) iron formulations, with emphasis on safety issues. Analyzed safety concerns include gastrointestinal side effects (oral iron) and risks of hypotension, anaphylaxis, infection, hypophosphatemia, oxidative stress and mortality (IV iron). Expert opinion: Low-to-moderate doses of oral iron supplementation remains as first line therapy for uncomplicated ID, but it has been scarcely discussed in the setting of inflammation. Confirmatory studies on the efficacy of newer oral iron formulations in this setting are needed. Compared with oral iron, short-term IV iron administration is more efficacious in ID correction, without significant safety concerns. However, long-term safety of IV iron maintenance therapy, head to head comparisons of IV iron preparations, pharmacological modulation of hepcidin and HIF, and extra-erythropoietic effects of iron are among the important areas of research.

A methodology is presented for comparison of alternative options for short-term and long-term irradiated fuel management. The value of this methodology is that all interested parties can take part in the analysis and derive the basis for decision-making. The methodology can answer questions as: When can uranium and plutonium recovered by reprocessing be recycled cost effectively in WWER? If reprocessing is not the short-term option chosen, is storage of irradiated fuel at the original licensed nuclear reactor site preferable to a separate storage-only-site? Are modular vault dry stores and cooling ponds which necessitate significant capital investment prior to deployment, more costly overall than their options? Should the most suitable form of irradiated fuel management be determined only by cost constraints? The key stages of the methodology are: 1) Assessing the current situation; 2) Assessing priorities; 3) Option/possible solutions; 4) Generic storage systems; 5) Cost/funding analysis; 6) Selection criteria; 7) Optioneering/evaluation. The conclusions that can be reached from this methodological approach lead to firm recommendations based on objective assessments. The methodology builds on existing expertise. It is not an imposed solution allowing an excellent exchange of knowledge and skills between the people involved

2016-01-01

Full Text Available Myotonic dystrophy type 1, also known as Steinert′s disease, is an autosomal dominant disorder with multisystemic clinical features affecting the skeletal and cardiac muscles, the eyes, and the endocrine system. Thiamine (vitamin B1 is a cofactor of fundamental enzymes involved in the energetic cell metabolism; recent studies described its role in oxidative stress, protein processing, peroxisomal function, and gene expression. Thiamine deficiency is critical mainly in the central and peripheral nervous system, as well as in the muscular cells. Our aim was to investigate the potential therapeutical effects of long-term treatment with thiamine in myotonic dystrophy type 1 in an observational open-label pilot study. We described two patients with myotonic dystrophy type 1 treated with intramuscular thiamine 100 mg twice a week for 12 or 11 months. We evaluated the patients using the grading of muscle strength according to Medical Research Council (MRC, the Muscular Impairment Rating Scale (MIRS, and the Modified Barthel index. High-dose thiamine treatment was well tolerated and effective in improving the motor symptomatology, particularly the muscle strength evaluated with the MRC scale, and the patients′ activities of daily living using the Modified Barthel Index. At the end of treatment, the MRC score was 5 in the proximal muscles and 2-4 in the distal muscles (the MRC score before the treatment was 3-4 and 1-3, respectively. The MIRS grade improved by 25% compared to baseline for both patients. In patient #1, the Modified Barthel Index improved by 44%, and in patient #2 by 29%. These findings suggest that clinical outcomes are improved by long-term thiamine treatment.

Cannabinoid Hyperemesis Syndrome: A Case Report of Cyclic Severe Hyperemesis and Abdominal Pain with Long-Term Cannabis Use

Directory of Open Access Journals (Sweden)

Julia Hermes-Laufer

2016-01-01

Full Text Available Introduction. Cannabinoid Hyperemesis Syndrome (CHS is a rare condition that includes cyclic severe vomiting in subjects who have been consuming large doses of cannabis for several years. One of the major diagnostic criteria is the alleviation of symptoms by hot showers. The syndrome was first described in 2004 and is so far neither completely understood nor well known. The latter leads to continued morbidity in concerned subjects and unnecessary expenses for futile investigations. Standard treatments of vomiting as 5-HT3 or D2-receptor antagonists have been shown to be ineffective in alleviating the symptoms. The only long-term satisfying treatment option is the complete abstinence from cannabis consumption. Case Summary. In this case report we describe a 26-year-old male Caucasian long-term cannabis consumer who repeatedly presented in our emergency room with cyclic severe nausea and vomiting ceased by hot showers and resistant to all other treatments. The final diagnosis was not established until his third visit to the ER. Conclusion. CHS is an important differential diagnosis in patients who present with cyclic vomiting and abdominal pain with a history of long-term cannabis use. Recognition of this syndrome is important in order to avoid unnecessary clinical testing and to help the patients break the cycle of drug use.

Many women will likely experience a sexual problem in their lifetime. Female sexual dysfunction is a broad term used to describe 3 categories of disorders of a multifactorial nature. Effective, but limited pharmacotherapeutic options exist to address female sexual dysfunction. The FDA recently approved the first agent for treatment of hypoactive sexual desire disorder in pre-menopausal women. Off-label use of hormonal therapies, particularly oestrogen and testosterone, are the most widely employed for female sexual dysfunction, particularly in post-menopausal women. Other drugs currently under investigation include phosphodiesterase inhibitors and agents that modulate dopamine or melanocortin receptors.

Full Text Available Charles E Argoff1, F Michael Gloth2 1Albany Medical College and Comprehensive Pain Center, Albany Medical Center, Albany, NY, USA; 2Johns Hopkins University School of Medicine, Baltimore, MD, USA Abstract: Osteoarthritis is common in patients ≥65 years of age. Although nonsteroidal anti-inflammatory drugs (NSAIDs are often prescribed for osteoarthritis pain, they pose age-related cardiovascular, renal, and gastrointestinal risks. Two topical NSAIDs, diclofenac sodium 1% gel (DSG and diclofenac sodium 1.5% in 45.5% dimethylsulfoxide solution (D-DMSO, are approved in the US for the treatment of osteoarthritis pain. Topical NSAIDs have shown efficacy and safety in knee (DSG, D-DMSO and hand (DSG osteoarthritis. Analyses of data from randomized controlled trials of DSG in hand and knee osteoarthritis demonstrate significant improvement of pain and function in both younger patients (<65 years and older patients (≥65 years and suggest good safety and tolerability. However, long-term safety data in older patients are limited. Topical NSAIDs can ease medication administration and help address barriers to pain management in older patients, such as taking multiple medications and inability to swallow, and are a valuable option for long-term care providers.

Pozo, David; Contreras, Javier; Caballero, Angel; de Andres, Antonio

2011-01-01

In competitive electricity markets, companies simultaneously offer their productions to obtain the maximum profits on a daily basis. In the long run, the strategies utilized by the electric companies lead to various long-term equilibria that can be analyzed with the appropriate tools. We present a methodology to find plausible long-term Nash equilibria in pool-based electricity markets. The methodology is based on an iterative market Nash equilibrium model in which the companies can decide upon their offer strategies. An exponential smoothing of the bids submitted by the companies is applied to facilitate the convergence of the iterative procedure. In each iteration of the model the companies face residual demand curves that are accurately modeled by Hermite interpolating polynomials. We introduce the concept of meta-game equilibrium strategies to allow companies to have a range of offer strategies where several pure and mixed meta-game Nash equilibria are possible. With our model it is also possible to model uncertainty or to generate price scenarios for financial models that assess the value of a generating unit by real options analysis. The application of the proposed methodology is illustrated with several realistic case studies. (author)

Long-term Results after CT-Guided Percutaneous Ethanol Ablation for the Treatment of Hyperfunctioning Adrenal Disorders

Directory of Open Access Journals (Sweden)

Nathan Elie Frenk

Full Text Available OBJECTIVES: To evaluate the safety and long-term efficacy of computed tomography-guided percutaneous ethanol ablation for benign primary and secondary hyperfunctioning adrenal disorders. METHOD: We retrospectively evaluated the long-term results of nine patients treated with computed tomography-guided percutaneous ethanol ablation: eight subjects who presented with primary adrenal disorders, such as pheochromocytoma, primary macronodular adrenal hyperplasia and aldosterone-producing adenoma, and one subject with Cushing disease refractory to conventional treatment. Eleven sessions were performed for the nine patients. The patient data were reviewed for the clinical outcome and procedure-related complications over ten years. RESULTS: Patients with aldosterone-producing adenoma had clinical improvement: symptoms recurred in one case 96 months after ethanol ablation, and the other patient was still in remission 110 months later. All patients with pheochromocytoma had clinical improvement but were eventually submitted to surgery for complete remission. No significant clinical improvement was seen in patients with hypercortisolism due to primary macronodular adrenal hyperplasia or Cushing disease. Major complications were seen in five of the eleven procedures and included cardiovascular instability and myocardial infarction. Minor complications attributed to sedation were seen in two patients. CONCLUSION: Computed tomography-guided ethanol ablation does not appear to be suitable for the long-term treatment of hyperfunctioning adrenal disorders and is not without risks.

One of the most important aspects to take into consideration when evaluating the outcome of treatment of impacted maxillary canines is the final periodontal status. The aim of the present study was to evaluate the long-term periodontal response of palatally impacted maxillary canines aligned using a codified procedure and the 'Easy Cuspid' compared with contralateral spontaneously erupted teeth. The periodontal conditions of the adjacent teeth were also considered. From an initial sample of 124 patients, 33 patients (24 females and 9 males) were selected. All patients who had undergone surgical orthodontic treatment conducted in accordance with a standardized protocol were recalled for follow-up at an average of 4.6 years after the end of treatment. The average treatment time was 29 months and the mean eruption time of the previously impacted tooth was 3.1 months. The average probing depth values showed no significant clinical differences. Probing depths recorded at the vestibular surface of the lateral incisor (P alignment of palatally impacted canines without damage to the periodontium.

Heat treatment effect on structure, phase composition and long-term rupture strength of the directional eutectics on the nickel base with γ/γ'-MeC structure is studied at 900-1100 deg C. It is shown that quenching from the temperature of complete dissolving of γ'-phase and ageing (900 deg - 30 hr) provide an optimum size and morphology of the γ-phase and an increase of the long-term rupture strength at 900 and 1000 deg C. Repeated thermal treatment of cimens tested during definite time restores their structure, mechanical properties and dimensions

Standard ophthalmological examination, i.e., visual acuity measurement, visual field test, refractometry, biomicroscopy, ophthalmoscopy, was performed.Results. First course of treatment with Retinalamin improved vision in 58.1 % of retinal degeneration patients. Visual fields improved in 64.5 % of cases. Repeated treatment courses (1‑2 times a year for 23‑25 years preserved residual vision in 55.6 % of patients and object vision in 11.1 % of cases. In retinal abiotrophy patients, residual vision preserved in 100 % of cases.Conclusions. In retinal degenerations, Retinalamin improves vision and visual fields and decreases total area of absolute scotomas even after the first treatment course as well as preserves vision in prolonged use. 

A Substance Called Food: Long-Term Psychodynamic Group Treatment for Compulsive Overeating.

Schwartz, Deborah C; Nickow, Marcia S; Arseneau, Ric; Gisslow, Mary T

2015-07-01

Obesity has proven difficult to treat. Many approaches neglect to address the deep-rooted underlying psychological issues. This paper describes a psychodynamically oriented approach to treating compulsive overeating as an addiction. Common to all addictions is a compulsion to consume a substance or engage in a behavior, a preoccupation with using behavior and rituals, and a lifestyle marked by an inability to manage the behavior and its harmful consequences. The approach represents a shift away from primarily medical models of intervention to integrated models focusing on the psychological underpinnings of obesity. Long-term psychodynamic group psychotherapy is recommended as a primary treatment.

This study is a survey of the factors of importance for the long term behaviour of bituminized ion exchange resins. Phenomena occurring in bituminized waste products affected by the treatment, storage and disposal are identified. Test methods have been developed for characterizing product properties, which are important for the long-term behaviour. The long-term properties of bituminized ion-exchange resins are studied in a repository environment with access of water equilibrated with concrete. In these circumstances the most important properties are related to the interactions of bituminized waste with the surrounding barriers. The most important phenomena are water uptake due to rehydration of the resins and subsequent swelling of the product

2016-06-03

Obesity is the main risk factor for obstructive sleep apnoea (OSA). The aim was to evaluate the long-term effect of continuous positive airway pressure (CPAP) on intraabdominal fat distribution in OSA patients. Fifty OSA patients with and 35 without CPAP treatment criteria were followed-up for 2 years. Visceral and subcutaneous adipose tissue (VAT and SAT) and preaortic intraabdominal fat (PIF) were assessed by sonography. In the non CPAP treated group, SAT and VAT mean values didn't change, while a significantly PIF growth was observed (55.19 [23.44] vs. 63.45 [23.94] mm, P=.021). In the CPAP treated group, VAT and PIF mean were not changed, while SAT decreased significantly (11.29 [5.69] vs. 10.47 [5.71] mm, P=.012). Long-term CPAP treatment produces intraabdominal fat redistribution and is associated with an anthropometric profile of lower cardiovascular risk in OSA patients.

Full text: Palaiseau Public demand and new regulations call for a growing stakeholder involvement in the protection of the public and the environment. On complex technical subjects prone to controversy, a useful advise to decision making processes can be provided by the pluralistic examination of the issues by a group of institutional and non-institutional experts. The French ministers for the environment, health, and industry created in 2005 a pluralistic expert group (GEP), started in mid-2006, to focus on the remediated uranium mines in the Limousin region of France. This group, which receives public funding, brings together experts with varied skills and backgrounds (from institutions, associations and industry, including independent and foreign experts). AREVA NC (COGEMA) the mine owner for the Haute Vienne sites has provided, on request of the administration, documents to assess the situation of the sites, and the French Institute for Radiological Protection and Nuclear Safety (IRSN) has been commissioned to produce a global expertise of this assessment. The GEP has been given the task of contributing this critical analysis and participating in the direction of the global expertise, with the aim to provide the authorities and the operator with recommendations on long-term management and monitoring options for the facilities. The group has also the duty to report to local stakeholders and to inform the general public. Work has been developed in three complementary areas: Improving the assessment of the source term and releases of transfer to the natural environment, including hydrogeological and geochemical studies as well as the characterisation of exhalations of radon; Developing a more thorough assessment of health and environmental impacts, including radiological and chemical risks. This includes, in addition to traditional methods, the first-of-a-kind application of an innovative methodology to assess radio-ecological impacts; - strengthening the

Treatment of the superficial femoral artery (SFA) has been among the least effective of all endovascular procedures in terms of long-term patency. The relatively small vessel lumen, in conjunction with a high plaque burden, slow flow, and a high frequency of primary occlusions, contributes to a considerable rate of acute technical failures. Because of these technical limitations a much effort has been made during the past years. This manuscript should summarize the hopes and limitations of different approaches such as brachytherapy, cutting balloons, stents and stent grafts, drug-eluting stents, and drug-coated balloons.

Chinn, Steven; Caldwell, William; Gritsenko, Karina

2016-04-01

This review article presents and summarizes up-to-date literature on the clinical manifestations, diagnosis, pathophysiological mechanisms, and treatment options for fibromyalgia patients. First, the most recent diagnostic criteria for fibromyalgia, as put forth by the American College of Rheumatology will be summarized. Clinical features, including chronic widespread pain, hyperalgesia, mood disorders, anxiety, and disturbed sleep patterns will be explored in-depth. The pathogenesis and pathophysiology of fibromyalgia involves alterations in multiple ascending and descending central nervous system pathways, as well as peripheral pathways, leading to heightened pain sensitivity. Risk factors have been studied extensively, and the most recent research focuses on various genetic influences and the contributions of stress and poor sleep. Lastly, the discussion in this article focuses on treatment options for fibromyalgia; some have been mainstay options for many years. Pharmacological agents include tricyclic antidepressants, anti-epileptic drugs, selective serotonin reuptake inhibitors, norepinephrine/serotonin reuptake inhibitors, as well as some investigational agents. The evidence behind non-pharmacologic treatments, including massage therapy, exercise, and acupuncture, are discussed.

Full Text Available Igor Kissin Department of Anesthesiology, Perioperative, and Pain Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA Background: For the past 30 years, opioids have been used to treat chronic nonmalignant pain. This study tests the following hypotheses: (1 there is no strong evidence-based foundation for the conclusion that long-term opioid treatment of chronic nonmalignant pain is effective; and (2 the main problem associated with the safety of such treatment – assessment of the risk of addiction – has been neglected. Methods: Scientometric analysis of the articles representing clinical research in this area was performed to assess (1 the quality of presented evidence (type of study; and (2 the duration of the treatment phase. The sufficiency of representation of addiction was assessed by counting the number of articles that represent (1 editorials; (2 articles in the top specialty journals; and (3 articles with titles clearly indicating that the addiction-related safety is involved (topic-in-title articles. Results: Not a single randomized controlled trial with opioid treatment lasting >3 months was found. All studies with a duration of opioid treatment ≥6 months (n = 16 were conducted without a proper control group. Such studies cannot provide the consistent good-quality evidence necessary for a strong clinical recommendation. There were profound differences in the number of addiction articles related specifically to chronic nonmalignant pain patients and to opioid addiction in general. An inadequate number of chronic pain-related publications were observed with all three types of counted articles: editorials, articles in the top specialty journals, and topic-in-title articles. Conclusion: There is no strong evidence-based foundation for the conclusion that long-term opioid treatment of chronic nonmalignant pain is effective. The above identified signs indicating neglect of addiction associated with the

Low water consumption in rural areas in Jordan had resulted in the production of concentrated grey water. Average COD, BOD and TSS values were 2568mg/l, 1056mg/l and 845mg/l, respectively. The average grey water generation was measured to be 14L/c.d. Three different treatment options were selected based on certain criterions, and discussed in this article. The examined treatment systems are septic tank followed by intermittent sand filter; septic tank followed by wetlands; and UASB-hybrid reactor. Advantages and disadvantages of each system are presented. It was concluded that UASB-hybrid reactor would be the most suitable treatment option in terms of compactness and simplicity in operation. The volume of UASB-hybrid reactor was calculated to be 0.268m(3) with a surface area of 0.138m(2) for each house having 10 inhabitants on average. Produced effluent is expected to meet Jordanian standards set for reclaimed water reuse in irrigating fruit trees.

Full Text Available Abstract Background Reduced vocal intensity is a core impairment of hypokinetic dysarthria in Parkinson’s disease (PD. Speech treatments have been developed to rehabilitate the vocal subsystems underlying this impairment. Intensive treatment programs requiring high-intensity voice and speech exercises with clinician-guided prompting and feedback have been established as effective for improving vocal function. Less is known, however, regarding long-term outcomes of clinical benefit in speakers with PD who receive these treatments. Methods A retrospective cohort design was utilized. Data from 78 patient files across a three year period were analyzed. All patients received a structured, intensive program of voice therapy focusing on speaking intent and loudness. The dependent variable for all analyses was vocal intensity in decibels (dBSPL. Vocal intensity during sustained vowel production, reading, and novel conversational speech was compared at pre-treatment, post-treatment, six month follow-up, and twelve month follow-up periods. Results Statistically significant increases in vocal intensity were found at post-treatment, 6 months, and 12 month follow-up periods with intensity gains ranging from 5 to 17 dB depending on speaking condition and measurement period. Significant treatment effects were found in all three speaking conditions. Effect sizes for all outcome measures were large, suggesting a strong degree of practical significance. Conclusions Significant increases in vocal intensity measured at 6 and 12 moth follow-up periods suggested that the sample of patients maintained treatment benefit for up to a year. These findings are supported by outcome studies reporting treatment outcomes within a few months post-treatment, in addition to prior studies that have reported long-term outcome results. The positive treatment outcomes experienced by the PD cohort in this study are consistent with treatment responses subsequent to other treatment

Background and purpose: This report presents long-term follow-up data from a prospective but unrandomized trial of a continuous 3.5-week course of accelerated radiation treatment (ART) used as primary treatment for patients with loco-regionally advanced head and neck cancer. Materials and methods: Ninety-three patients in three centres in New Zealand and Australia were treated with ART (59.40 Gy in 33 fractions over 24-25 days). Their disease originated from three anatomical regions (oral cavity, 35 patients; pharynx, 31 patients; larynx, 27 patients). Seventy-nine of these patients had stage III or IV cancers. Results: Follow-up ranged from 68 to 203 months (median 139 months). Loco-regional (LR) failure occurred in 52 patients leading to a 10-year actuarial expectation of LR control of 38%. The actuarial expectation of LR control at 10 years was highly dependent on stage and for stage III, IVA and IVB patients it was 57±8.1%, 32±1.7% and 7±0.5%, respectively. Multivariate analysis could not confirm an independent impact of primary site or histological differentiation on LR failure. Two patients died of acute toxicity of treatment and six patients developed grade 3/4 late complications affecting soft tissues only, yielding an actuarial expectation of complications of this severity at 5 years of 9%. No cases of osteoradionecrosis or myelitis were observed. Conclusion: This ART, which has proved easy to use at a number of large and small centres, has produced encouraging long-term LR control at a cost of limited soft tissue morbidity.

It is controversial whether patients fare better with conservative or surgical treatment in certain stages of acute diverticulitis (AD), in particular when phlegmonous inflammation or covered micro- or macro-perforation are present. The aim of this study was to determine long-term quality of life (QoL) for AD patients who received either surgery or conservative treatment in different stages. We included patients treated for AD at the University Hospital Grosshadern, Munich, Germany, between January 1, 2000, and December 31, 2010. Patients were classified by the Hansen and Stock (HS) classification, the modified Hinchey classification, and the German classification of diverticular disease (CDD). Pre-therapeutic staging was based on multidetector computed tomography. Long-term QoL was assessed by the Cleveland Global Quality of Life (CGQL) questionnaire, the Short Form 36 (SF-36), and the Gastrointestinal Quality of Life Index (GIQLI). Data are mean ± SEM. Patients with phlegmonous AD (HS type 2a, Hinchey Ia and CDD 1b, respectively) had a better long-term QoL on the GIQLI when they were operated (78.5 ± 2.5 vs. 70.7 ± 2.1; p life, patients fare better after elective sigmoid colectomy when abscess size exceeds 1 cm.

Aim: To assess the short and medium-term efficacy and safety of a novel, minimally invasive therapeutic option combining automated percutaneous lumbar discectomy, intradiscal ozone injection, and caudal epidural: ozone-augmented percutaneous discectomy (OPLD). Materials and methods: One hundred and forty-seven patients with a clinical and radiological diagnosis of discogenic sciatica who were refractory to initial therapy were included. Fifty patients underwent OPLD whilst 97 underwent a further caudal epidural. Outcomes were evaluated using McNab's score, improvement in visual analogue score (VAS) pain score, and requirement for further intervention. Follow-up occurred at 1 and 6 months, and comparison was made between groups. Results: OPLD achieved successful outcomes in almost three-quarters of patients in the short and medium term. OPLD achieved superior outcomes at 1 and 6 months compared to caudal epidural. There was a reduced requirement for further intervention in the OPLD group. No significant complications occurred in either group. Discussion: OPLD is a safe and effective treatment for patients with refractory discogenic sciatica in the short and medium term. OPLD has the potential to offer an alternative second-line minimally invasive treatment option that could reduce the requirement for surgery in this patient cohort. - Highlights: • Discogenic sciatica is a common condition which causes significant morbidity. • Ozone augmented percutaneous lumbar discectomy (OPLD) is a novel treatment. • Comparison was made to caudal epidural injection. • All outcomes were superior in the OPLD treatment group. • OPLD appears is an effective treatment for refractory discogenic sciatica

Weis, J; Faller, H

2012-04-01

Although cancer incidence rates are increasing, recent statistical studies suggest that cancer patients are showing higher cure rates as well as improved overall survival rates for most cancer locations. These advances are explained by improved strategies in early diagnoses as well as improved cancer therapies. Therefore, the number of long-term cancer survivors has also increased, but only few studies, especially within the last years, have focused on psychosocial issues of this subgroup. Some studies show that overall quality of life of long-term cancer survivors is quite high and comparable to that of the normal population. Nevertheless, a substantial percentage of former patients shows reduced quality of life and suffers from various sequelae of cancer and its treatment. This review focuses on the most common psychosocial issue of long-term survivors such as reduced psychological wellbeing, neuropsychological deficits and cancer-related fatigue syndrome. Finally, recommendations for problem-oriented interventions as well as improvement of psychosocial care of long-term survivors are given.

Non-Antidepressant Long-term Treatment in Post-Traumatic Stress Disorder (PTSD).

Post-traumatic stress disorder (PTSD) is a frequent and disabling condition that occurs after exposure to a traumatic event, and Selective Serotonin Reuptake Inhibitors (SSRIs) are considered the first-line treatment approach for this disorder. However, a large proportion of patients remain symptomatic and other pharmacological agents have been investigated, based on the understanding of the underlying biological dysfunctions of PTSD. We conducted a review of the literature on the pharmacological options for PTSD other than the antidepressants, using MedLine and Web of Science databases, with search terms including the pharmacologic class of each agent plus PTSD, or pharmacotherapy, or fear conditioning. The literature review covered articles published until august 2012, including reviews and original articles. Agents like antipsychotics, anticonvulsants, benzodiazepines, anti-adrenergic agents, have been studied in randomized clinical trials (RCTs), with general positive results for antipsychotics, especially as adjunct therapy, and for prazosin for sleep-related disturbances. However, one important target for novel medications is the modulation of the fear conditioning process, through the alteration of retrieval/reconsolidation or enhancement of fear extinction. This is traditionally targeted in prolonged exposure therapy, but pre-clinical findings from studies investigating agents like propanolol, clonidine, N-Methyl-D-aspartic Acid Receptor (NMDAR) compounds, 3,4-methylenedioxy-N-methylamphetamine (MDMA) and cannabinoids, indicate promising results in affecting the fear conditioning process and thus improving PTSD core symptoms. Antipsychotics can be considered a reasonable alternative option to PTSD, with the largest body of evidence for risperidone, even though larger RCTs are warranted. Prazosin is also a promising agent, especially for sleep-related disturbances, while anticonvulsants and benzodiazepines lack empirical support. However, the most promising

Full Text Available Aim. To evaluate feasibility and long-term outcome after hepatic resection for noncolorectal, nonneuroendocrine, and nonsarcoma (NCNNNS liver metastases in a single center. Methods. We retrospectively reviewed our experience on patients who underwent surgery for NCNNNS liver metastases from 1995 to 2015. Patient baseline characteristics, tumor features, treatment options, and postoperative outcome were retrieved. Results. We included 47 patients. The overall 5-year survival (OS rate after hepatectomy was 27.6%, with a median survival of 21 months. Overall survival was significantly longer for patients operated for nongastrointestinal liver metastases when compared with gastrointestinal (41 versus 10 months; p=0.027. OS was significantly worse in patients with synchronous metastases than in those with metachronous disease (10 versus 22 months; p=0.021. The occurrence of major postoperative complication negatively affected long-term prognosis (OS 23.5 versus 9.0 months; p=0.028. Preoperative tumor characteristics (number and size of the lesions, intraoperative features (extension of resection, need for transfusions, and Pringle’s maneuver, and R0 at pathology were not associated with differences in overall survival. Conclusion. Liver resection represents a possible curative option for patients with NCNNNS metastases. The origin of the primary tumor and the timing of metastases presentation may help clinicians to better select which patients could take advantages from surgical intervention.

Seventy-four children (43 with chronic constipation, 31 with constipation and encopresis) treated with polyethylene glycol 3350 (PEG) for longer than 3 months were studied to assess long-term efficacy. The mean duration of PEG therapy was 8.4 months (range, 3-30). Weekly stool frequency, stool consistency, and symptoms associated with constipation improved significantly with PEG therapy in all 74 patients. In 31 children with encopresis, soiling ceased completely in 16 patients and frequency of soiling decreased significantly in all others. The average effective long-term dose of PEG was 0.7 g/kg/day. Long-term PEG therapy is effective for the treatment of chronic constipation with and without encopresis in children.

In 18 patients, therapy was discontinued after a short period because of inefficacy or side effects. The activity of uveitis (using Standardized Uveitis Nomenclature [SUN] criteria and clinical examination and arthritis (number of swollen or active joints was evaluated at the start and at end of the study.Results: At the end of the study, uveitis was under good clinical control in two thirds of 54 patients (31% did not need any local treatment and 35% used only 1–2 corticosteroid drops a day, and one third had active uveitis (at least three corticosteroid drops a day. According to SUN criteria, adalimumab treatment for uveitis showed improved activity (a two-fold decrease in uveitis activity in 28% of patients, with a moderate response in 16 patients, no change in a further 16 patients, and worsening activity (a two-fold increase in uveitis activity in 13% of patients. The overall proportion of patients with active arthritis decreased. At the beginning of the study, 69% of patients with uveitis had more than two active joints, and at the end of the study only 27% had active joint disease. In 27 patients with juvenile idiopathic arthritis without uveitis on adalimumab, the number of active joints decreased from 93% to 59%. Systemic corticosteroid treatment could be stopped in 22% of patients with uveitis and in 11% of those without uveitis. Most of the

Proffen, B; von Keudell, A; Vavken, P

The treatment of cartilage defects has seen a shift from replacement to regeneration in the last few years. The rationale behind this development is the improvement in the quality-of-care for the growing segment of young patients who are prone to arthroplasty complications because of their specific characteristics - young age, high level of activity, high demand for functionality. These days, two of the most popular regenerative treatments are microfracture and autologous chondrocyte implantation (ACI). Although these new options show promising results, no final algorithm for the treatment of cartilage lesions has been established as yet. The objective of this review is to describe and compare these two treatment options and to present an evidence-based treatment algorithm for focal cartilage defects. Microfracture is a cost-effective, arthroscopic one-stage procedure, in which by drilling of the subchondral plate, mesenchymal stem cells from the bone marrow migrate into the defect and rebuild the cartilage. ACI is a two-stage procedure in which first chondrocytes are harvested, expanded in cell culture and in a second open procedure reimplanted into the cartilage defect. Microfracture is usually used for focal cartilage defects osteophyte, and for the ACI patient, periosteal hypertrophy and the need for two procedures in ACI. Only a few studies provide detailed and evidence-based information on a comparative assessment. These studies, however, are showing widely similar clinical outcomes but better histological results for ACI, which are likely to translate into better long-term outcomes. Although evidence-based studies comparing microfracture and ACI have not found significant differences in the clinical outcome, the literature does show that choosing the treatment based on the size and characteristics of the osteochondral lesion might be beneficial. The American Association of Orthopedic Surgeons suggest that contained lesions < 4 cm2 should be treated by

Scarring is the consequence of surgery, trauma or different skin diseases. Apart from fresh, immature scars,that transform into mature scars over the course of would healing and that do not require further treatment,linear hypertrophic scars, widespread hypertrophic scars, keloids and atrophic scars exist. Symptoms like pruritusand pain, stigmatization as well as functional and aesthetic impairments that are very disturbing for the affected patients can bethe basis for the desire for treatment. Today, a multitude of options for the treatment and prevention of scars exists. Topical agents based on silicone or onion extract, intralesional injections of cristalline glucocorticoids (oftentimes in combinationwith cryotherapy) or 5-Fluorouracil as well as ablative and nonablative laser treatment are used. Current guidelines summarize the multitude of available treatment options and the currently available datafor the treating physicians, allowing them to make clear therapy recommendations for every single scar type. Relieving patients of their discomfort and doing their aesthetic demands justice is thus possible. Apart from scar prevention becoming more and more important, the increased use of modernlaser treatment options constitutes a key point in clinical scar treatment. At the same time the attention is turned to evaluating current therapeutic options with the help of contemporary study designs so as to graduallyimprove the level of evidence in scar treatment. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

The purpose of this study was to determine the long-term clinical outcome of patients with ectopic atrial tachycardias treated surgically. Ectopic atrial tachycardia is an uncommon arrhythmia that can be symptomatic and is associated with the development of a cardiomyopathy. Management strategies are not well defined because of the paucity of data on the long-term effectiveness of pharmacologic and nonpharmacologic therapies. The long-term clinical impact of medical and surgical therapy was determined in 15 consecutive patients with ectopic atrial tachycardia. All 15 patients were initially treated with antiarrhythmic drugs (mean 5.7 +/- 2.2 drugs/patient). An effective drug regimen was identified in only 5 (33%) of the 15 patients; the remaining 10 patients were treated surgically. In each, individualized surgical procedures were guided by computer-assisted intraoperative mapping, with atrial plaques comprising up to 156 electrodes. Focal ablation was performed in four patients and atrial isolation procedures in six. The 10 patients treated surgically were followed up a mean of 4 +/- 3.2 years. Ectopic atrial tachycardia recurred in one patient. A permanent pacemaker was implanted in two patients, one of whom also required reoperation for constrictive pericarditis. There were no operative deaths. Ectopic atrial tachycardia recurred in three (60%) of the five patients discharged on antiarrhythmic drug therapy during a mean follow-up interval of 6.4 +/- 4.3 years. There was one nonarrhythmic death. Map-guided surgery demonstrated long-term efficacy in abolishing symptoms in 9 of the 10 patients with ectopic atrial tachycardia. Results demonstrate that surgery is effective for patients with ectopic atrial tachycardias who are not easily treated with antiarrhythmic drugs.

The Municipal Solid Waste (MSW) Options Report explored different MSW management options for 3 community sizes: 20,000, 80,000 and 200,0000 people. It was released at a time when many communities were developing waste management plans to cost-effectively reduce environmental impacts and conserve landfill capacity. The purpose of this report was to provide a greater understanding on the environmental, social, economic, energy recovery/utilization and greenhouse gas (GHG) considerations of MSW management. The report also demonstrated the interrelationships between the management of organics and residuals. It was based on information from existing waste diversion and organics management options and emerging residual treatment technology options. The following organics management and residual treatment disposal options were evaluated: composting; anaerobic digestion; sanitary landfills; bioreactor landfills; and thermal treatment. Composting was examined with reference to both source separated organics (SSO) and mixed waste composting. SSO refers to the separation of materials suitable for composting solid waste from households, while mixed waste composting refers to the manual or mechanical removal of recyclable material from the waste, including compost. The composting process was reviewed along with available technologies such as non-reactor windrow; aerated static pile; reactor enclosed channel; and, container tunnel. An evaluation of SSO and mixed waste composting was then presented in terms of environmental, social, financial and GHG impacts. refs., tabs., figs.

Long-term Strategic Planning for a Resilient Metro Colombo: An Economic Case for Wetland Conservation and Management

Science.gov (United States)

Rozenberg, J.

2015-12-01

Colombo faces recurrent floods that threaten its long-term economic development. Its urban wetlands have been identified by local agencies as a critical component of its flood reduction system, but they have declined rapidly in recent years due to continuous infilling, unmanaged land development and dredging to create lakes. In collaboration with government agencies, NGOs and local universities, the World Bank has carried out a Robust Decision Making analysis to examine the value of Colombo urban wetlands, both in the short-term and long-term, and identify what are the most viable strategies available to increase the city's flood resilience in an unclear future (in terms of climate change and patterns of urban development). This has involved the use of numerous hydrological and socio-economic scenarios as well as the evaluation of some wetlands benefits, like ecosystem services, wastewater treatment, or recreational services. The analysis has determined that if all urban wetlands across the Colombo catchment were lost, in some scenarios the metropolitan area would have to cope with an annual average flood loss of approximately 1% of Colombo GDP in the near future. For long-term strategies, trade-offs between urban development, lake creation and wetland conservation were analyzed and it was concluded that an active management of urban wetlands was the lowest regret option. Finally, the analysis also revealed that in the future, with climate change and fast urban development, wetlands will not be sufficient to protect Colombo against severe floods. Pro-active urban planning and land-use management are therefore necessary, both to protect existing wetlands and to reduce future exposure. The use of many different scenarios, the consideration of several policy options, and the open participatory process ensured policy-makers' buy-in and lead to the decision to actively protect urban wetlands in Colombo.

Full Text Available Abstract Background Patients with IBD and chronic inflammation refractory to conventional therapy often demonstrate higher risk of serious complications. Combinations of immunosuppression and biological treatment as well as surgical intervention are often used in this patient group. Hence, there is need for additional treatment options. In this observational study, focused on re-treatment and long-term results, Granulocyte/Monocyte Adsorption (GMA, Adacolumn® treatment has been investigated to study efficacy, safety and quality of life in IBD-patients with chronic activity. Methods Fifteen patients with ulcerative colitis and 25 patients with Crohn's disease, both groups with chronically active inflammation refractory to conventional medication were included in this observational study. The patients received 5-10 GMA sessions, and the clinical activity was assessed at baseline, after each completed course, and at week 10 and 20 by disease activity index, endoscopy and quality of life evaluation. Relapsed patients were re-treated by GMA in this follow-up study up to 58 months. Results Clinical response was seen in 85% and complete remission in 65% of the patients. Ten patients in the UC-group (66% and 16 patients in the CD-group (64% maintained clinical and endoscopic remission for an average of 14 months. Fourteen patients who relapsed after showing initial remission were re-treated with GMA and 13 (93% went into a second remission. Following further relapses, all of seven patients were successfully re-treated for the third time, all of three patients for the fourth time and one for a fifth time. Conclusions IBD-patients with chronic inflammation despite conventional therapy seem to benefit from GMA. Re-treatment of relapsing remission patients seems to be effective.

Brain dopamine dysfunction in attention deficit/hyperactivity disorder (ADHD) could explain why stimulant medications, which increase dopamine signaling, are therapeutically beneficial. However while the acute increases in dopamine induced by stimulant medications have been associated with symptom improvement in ADHD the chronic effects have not been investigated. We used positron emission tomography and [(11)C]cocaine (dopamine transporter radioligand) to measure dopamine transporter availability in the brains of 18 never-medicated adult ADHD subjects prior to and after 12 months of treatment with methylphenidate and in 11 controls who were also scanned twice at 12 months interval but without stimulant medication. Dopamine transporter availability was quantified as non-displaceable binding potential using a kinetic model for reversible ligands. Twelve months of methylphenidate treatment increased striatal dopamine transporter availability in ADHD (caudate, putamen and ventral striatum: +24%, p<0.01); whereas there were no changes in control subjects retested at 12-month interval. Comparisons between controls and ADHD participants revealed no significant difference in dopamine transporter availability prior to treatment but showed higher dopamine transporter availability in ADHD participants than control after long-term treatment (caudate: p<0.007; putamen: p<0.005). Upregulation of dopamine transporter availability during long-term treatment with methylphenidate may decrease treatment efficacy and exacerbate symptoms while not under the effects of the medication. Our findings also suggest that the discrepancies in the literature regarding dopamine transporter availability in ADHD participants (some studies reporting increases, other no changes and other decreases) may reflect, in part, differences in treatment histories.

Craniopharyngioma in Children: Long-term Outcomes

STEINBOK, Paul

2015-01-01

The survival rate for childhood craniopharyngioma has been improving, with more long-term survivors. Unfortunately it is rare for the patient to be normal, either from the disease itself or from the effects of treatment. Long-term survivors of childhood craniopharyngioma suffer a number of impairments, which include visual loss, endocrinopathy, hypothalamic dysfunction, cerebrovascular problems, neurologic and neurocognitive dysfunction. Pituitary insufficiency is present in almost 100%. Visual and hypothalamic dysfunction is common. There is a high risk of metabolic syndrome and increased risk of cerebrovascular disease, including stroke and Moyamoya syndrome. Cognitive, psychosocial, and emotional problems are prevalent. Finally, there is a higher risk of premature death among survivors of craniopharyngioma, and often this is not from tumor recurrence. It is important to consider craniopharyngioma as a chronic disease. There is no perfect treatment. The treatment has to be tailored to the individual patient to minimize dysfunction caused by tumor and treatments. So “cure” of the tumor does not mean a normal patient. The management of the patient and family needs multidisciplinary evaluation and should involve ophthalmology, endocrinology, neurosurgery, oncology, and psychology. Furthermore, it is also important to address emotional issues and social integration. PMID:26345668

2010-01-01

Advanced therapy medicinal products (ATMPs) are an innovative treatment option. To promote timely access of the innovative medicinal product and to safeguard public health, new elements have been introduced into legislation. A key element of the ATMP regulation is the requirement for long-term follow-up on safety and efficacy of patients enrolled in clinical trials with ATMPs, which is beyond the routine requirements on pharmacovigilance. For gene therapy medicinal products, a guideline on long-term follow-up, which lays down the technical requirements, is available. A further key element of the ATMP regulation is the traceability of the starting materials used to manufacture the ATMP. A common European coding system is imperative to ensure the traceability of starting materials, especially across the borders of European Member States.

Huntley, E; Smith, L

1999-12-01

Encopresis is a major problem in high-dependency fields such as intellectual disability. Little information is available with respect to either the prevalence or aetiology of encopresis, probably because it is widely regarded as part and parcel of the handicapping condition. Consequently, treatment reports are rare and confined to a small number of case studies. There is a dearth of long-term follow-up on the behavioural treatment of encopresis in the general population, and no long-term follow-up studies are available for the treatment of encopresis in intellectual disability. The present report provides follow-up data for nine out of 10 people with mainly severe intellectual disability who had received behavioural treatment for primary retentive or non-retentive encopresis between 5 and 17 years previously. Six out of the nine subjects for whom data were available were accident-free and a further two clients were very substantially improved. Interestingly, those whose former encopresis was retentive in nature maintained more successfully, despite the severity of their original impaction. The limitations of the present study are discussed.

Significant quantities of weapons-usable fissile materials (primarily plutonium and highly enriched uranium) have become surplus to national defense needs both in the US and Russia. These stocks of fissile materials pose significant dangers to national and international security. The dangers exist not only in the potential proliferation of nuclear weapons but also in the potential for environmental, safety and health consequences if surplus fissile materials are not properly managed. As announced in the Notice of Intent (NOI) to prepare a Programmatic Environmental Impact Statement (PEIS), the Department of Energy is currently conducting an evaluation process for disposition of surplus weapons-usable fissile materials determined surplus to National Security needs, and long-term storage of national security and programmatic inventories, and surplus weapons-usable fissile materials that are not able to go directly from interim storage to disposition. An extensive set of long-term storage and disposition options was compiled. Five broad long-term storage options were identified; thirty-seven options were considered for plutonium disposition; nine options were considered for HEU disposition; and eight options were identified for Uranium-233 disposition. Section 2 discusses the criteria used in the screening process. Section 3 describes the options considered, and Section 4 provides a detailed summary discussions of the screening results.

This report presents a comparative study of long-term energy demand and potential greenhouse gas emissions projections from energy demand and supply sectors in Bangladesh covering the period 2000 to 2020. The study was conducted employing the IAEA's tool ENPEP- BALANCE model. This study presents a reliable energy system plan with minimal carbon emission for the country. Primary energy demands distributed by energy carriers and electricity demand have been projected based on macro-economic growth scenarios constructed for national energy policy of 1996. The conservation of indigenous energy resources was emphasized to build a long-term secured energy supply system. The potential energy supply options including nuclear energy and prospective greenhouse gas mitigation options were analyzed

Our objective was to analyze the long-term oncologic outcomes of fertility-preserving hormonal treatment with medroxyprogesterone acetate (MPA) in patients with APA. In a retrospective chart review, we identified patients with APA who were treated with MPA for fertility preservation at our hospital between 2001 and 2011. Eighteen patients with histologically diagnosed APA were identified. Clinical data including treatment, obstetrical, and oncologic outcomes were recorded. The mean observation period was 77.6 months (median 73.5, range 22-142), and the mean age was 33.6 years. Four patients also developed well-differentiated endometrial carcinoma. After the treatment, 14 patients (77.8 %) achieved either a complete response or partial response. Eight patients experienced recurrence, while four experienced persistent disease. Ten patients (55.6 %) eventually underwent hysterectomy. The median time to hysterectomy was 40.3 months (range 24-68). Nine patients progressed to endometrial cancer, and one experienced persistent APA. Among younger patients (years of age), four out of five patients who were married could have children. Seven patients (38.9 %) showed no evidence of the disease during the observation period (median 60 months, range 22-117 months). No one died because of the disease during the observation period. MPA yields a high response rate in APA, and if only younger patients are considered, a favorable pregnancy rate can be obtained. However, because recurrence rate is high, long-term follow-up under supervision of a trained gynecologic oncologist is required. To confirm MPA's utility, multi-center collaboration would be warranted.

The objective of the CEA studies carried out under research topic 3 (long-term interim storage) of the 1991 French radioactive waste management law is to demonstrate the industrial feasibility of a comprehensive, flexible interim storage facility by thoroughly evaluating and comparing all the basic components of various interim storage concepts. In this context, the CEA is considering reference solutions or concepts based on three primary components (the package, the interim storage facility and the site) suitable for determining the specifications of a very long-term solution. Some aspects are examined in greater detail, such as the implementation of long-term technologies, conditioning processes ensuring the absence of water and contamination in the facility, or allowance for radioactive decay of the packages. The results obtained are continually compiled in reports substantiating the design options. These studies should also lead to an overall economic assessment in terms of the capital and operating cost requirements, thereby providing an additional basis for selecting the design options. The comparison with existing industrial facilities highlights the technical and economic progress represented by the new generation of interim storage units. (authors)

Long-term cetuximab treatment can lead to acquired resistance, and tumor progression and/or new lesions often occur. The present report describes a case of lower gingival squamous cell carcinoma with brain metastasis during long-term cetuximab treatment in a 60-year-old man, including findings of an immunohistochemical study. The resected primary tumors, biopsy of the lung metastasis before administration of cetuximab, and brain metastasis specimens mediated by cetuximab were immunohistochemically examined. Histologically, the metastatic brain lesion showed hyperkeratinizing tumor cells with deeply stained irregular nuclei with necrotizing tumor cells, and a decrease in cell density was exhibited in part of the tumor nest. Moreover, the brain lesion was less malignant compared with the primary tumor and metastatic lung lesions. Immunohistochemically, the metastatic brain lesions showed low expression of epidermal growth factor receptor (EGFR) and high expression of N-cadherin compared with the primary tumor and metastatic lung lesions. These results suggest that acquired resistance to cetuximab may be associated with low EGFR expression and increased epithelial-to-mesenchymal transition potential.

Objectives: To evaluate the safety and long-term efficacy of computed tomography-guided percutaneous ethanol ablation for benign primary and secondary hyper functioning adrenal disorders. Method: We retrospectively evaluated the long-term results of nine patients treated with computed tomography guided percutaneous ethanol ablation: eight subjects who presented with primary adrenal disorders, such as pheochromocytoma, primary macro nodular adrenal hyperplasia and aldosterone-producing adenoma, and one subject with Cushing disease refractory to conventional treatment. Eleven sessions were performed for the nine patients. The patient data were reviewed for the clinical outcome and procedure-related complications over ten years. Results: Patients with aldosterone-producing adenoma had clinical improvement: symptoms recurred in one case 96 months after ethanol ablation, and the other patient was still in remission 110 months later. All patients with pheochromocytoma had clinical improvement but were eventually submitted to surgery for complete remission. No significant clinical improvement was seen in patients with hypercortisolism due to primary macro nodular adrenal hyperplasia or Cushing disease. Major complications were seen in five of the eleven procedures and included cardiovascular instability and myocardial infarction. Minor complications attributed to sedation were seen in two patients. Conclusion: Computed tomography-guided ethanol ablation does not appear to be suitable for the long-term treatment of hyper functioning adrenal disorders and is not without risks. (author)

Johnson, Matthew W; Garcia-Romeu, Albert; Griffiths, Roland R

2017-01-01

A recent open-label pilot study (N = 15) found that two to three moderate to high doses (20 and 30 mg/70 kg) of the serotonin 2A receptor agonist, psilocybin, in combination with cognitive behavioral therapy (CBT) for smoking cessation, resulted in substantially higher 6-month smoking abstinence rates than are typically observed with other medications or CBT alone. To assess long-term effects of a psilocybin-facilitated smoking cessation program at ≥12 months after psilocybin administration. The present report describes biologically verified smoking abstinence outcomes of the previous pilot study at ≥12 months, and related data on subjective effects of psilocybin. All 15 participants completed a 12-month follow-up, and 12 (80%) returned for a long-term (≥16 months) follow-up, with a mean interval of 30 months (range = 16-57 months) between target-quit date (i.e., first psilocybin session) and long-term follow-up. At 12-month follow-up, 10 participants (67%) were confirmed as smoking abstinent. At long-term follow-up, nine participants (60%) were confirmed as smoking abstinent. At 12-month follow-up 13 participants (86.7%) rated their psilocybin experiences among the five most personally meaningful and spiritually significant experiences of their lives. These results suggest that in the context of a structured treatment program, psilocybin holds considerable promise in promoting long-term smoking abstinence. The present study adds to recent and historical evidence suggesting high success rates when using classic psychedelics in the treatment of addiction. Further research investigating psilocybin-facilitated treatment of substance use disorders is warranted.

Objective: To compare the long-term dental treatment effects, oral health habits and oral-health-related qualities of life of children treated under general anesthesia (GA) and passive restraint (PR), respectively. Methods: Twenty seven 2 to 4-year-old children treated under GA and thirty four children treated under PR were recruited in the Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology. Up to 2 years after the treatment, a follow up assessment was conducted. The data of general information, dental plaque level and the unplanned treatments were recorded and analyzed. The questionnaire of oral health habits and early childhood oral health impact scale (ECOHIS) for each child was also completed and analyzed. The survival rate and median survival time of the deciduous teeth were calculated. Multivariate analysis was performed by using Cox proportional hazard model. Results: Twenty-five children under GA and 32 under PR were finally included, with a total of 1 098 deciduous teeth. The postoperative dental plaque indicesin both GA and PR groups had significantly improved than that of before the treatments ( P= 0.019, P< 0.001). The oral health habits had also improved, and the improvement in PR group was more obvious than that in GA group. Totally 128 teeth (27.0%) appeared unplanned treatments in GA group and 232 teeth (37.2%) in PR group during the follow-ups. The new caries and recurrent caries in PR group were significantly more than that in GA group ( P< 0.001, P= 0.012). No significant differences were found between the two groups in restoration failure, secondary caries and endodontic diseases ( P= 0.129, P= 0.822, P= 0.642). However, the time of occurrence of endodontic disease and secondary caries in GA group were significantly longer than that in PR group ( P< 0.01, P< 0.001). The median survival time of teeth in GA group was 1 018 days comparing to 944 days in PR group. The difference was statistically significant ( P

To assess the short and medium-term efficacy and safety of a novel, minimally invasive therapeutic option combining automated percutaneous lumbar discectomy, intradiscal ozone injection, and caudal epidural: ozone-augmented percutaneous discectomy (OPLD). One hundred and forty-seven patients with a clinical and radiological diagnosis of discogenic sciatica who were refractory to initial therapy were included. Fifty patients underwent OPLD whilst 97 underwent a further caudal epidural. Outcomes were evaluated using McNab's score, improvement in visual analogue score (VAS) pain score, and requirement for further intervention. Follow-up occurred at 1 and 6 months, and comparison was made between groups. OPLD achieved successful outcomes in almost three-quarters of patients in the short and medium term. OPLD achieved superior outcomes at 1 and 6 months compared to caudal epidural. There was a reduced requirement for further intervention in the OPLD group. No significant complications occurred in either group. OPLD is a safe and effective treatment for patients with refractory discogenic sciatica in the short and medium term. OPLD has the potential to offer an alternative second-line minimally invasive treatment option that could reduce the requirement for surgery in this patient cohort.

Long-term surgical-orthodontic management of hemimandibular hyperplasia.

Science.gov (United States)

Bennett, Samuel C; Goonewardene, Mithran S

2016-05-01

Hemimandibular hyperplasia (HH), also known as hemimandibular hypertrophy, is characterised by excessive unilateral three-dimensional growth of the mandible after birth. Vertical unilateral elongation of the mandible becomes clinically evident as a rare form of vertical facial asymmetry. Aberrant growth of the facial skeleton affects the developing dentition and the dental compensatory mechanism is usually unable to maintain optimal occlusal relationships. The resulting malocclusion is effectively managed by combined surgical-orthodontic care to address the facial, skeletal and dental problems that confront clinicians. Orthodontists are advised to assess patients with HH during the post-treatment retention stage for continuing mandibular growth and assess the stability of treatment outcomes with long-term follow-up and records as required. To present a case of hemimandibular hyperplasia treated successfully by combined surgical-orthodontic care and evaluated for stability over a seven-year follow-up period. Surgical-orthodontic management was accomplished in four stages: 1) pre-surgical orthodontic; 21 surgical; 3) post-surgical orthodontic; and 4) post-treatment orthodontic retention. Complete orthodontic records, including extra- and intra-oral photographs, study models, and cephalograms plus panoramic radiographs were taken at the pretreatment, post-treatment, and seven-year orthodontic retention time-points. Facial, skeletal and dental goals were achieved in the three planes of space and the long-term stability of the treatment results was shown during a post-treatment orthodontic retention period of seven years. Hemimandibular hyperplasia is a true growth anomaly which may be managed effectively. Clinicians may expect successful long-term correction and stability by utilising a comprehensive surgical-orthodontic treatment approach.

Among the many difficult problems presented by patients with spinal cord injuries, management of ischial pressure ulcers remains challenging for reconstructive surgeons. This study describes the long-term outcome of using posterior-thigh fasciocutaneous flaps for the treatment of ischial pressure sores. Between January 1999 and June 2003, 12 patients with ischial sores were enrolled in this study. All the patients underwent early aggressive surgical debridement followed by surgical reconstruction with a laterally based posterior-thigh fasciocutaneous flap. The follow-up period ranged from 24 months to 97 months (mean, 62 months). All the flaps survived, and there were no partial flap losses. Primary-wound healing occurred in all the cases. In two patients, Grade II ischial pressure sores recurred 24 months and 27 months after the operation. There was no recurrence in the other 10 patients. The posterior-thigh fasciocutaneous pedicled flap was a good method for treating ischial bed sores. This flap could be used to treat recurrences observed after primary bed-sore treatment with other methods. The flap was easy to raise, and it did not cause any donor-site morbidity. The long-term outcome of using posterior-thigh fasciocutaneous flaps for the treatment of ischial pressure sores was generally good. (c) Thieme Medical Publishers.

Suzuki, T.

1995-01-01

Despite comfortable predictions on short to mid-term uranium resources, there is still a concern about long-term availability of competitive uranium resources. In order to achieve substantial uranium saving, early introduction of Fast Breeder Reactor (FBR) is desirable. But it is also known that rapid introduction of FBR could result in plutonium storage. Will there be enough plutonium on a global scale to sustain fast FBR growth? is there any other way to save uranium resource? This paper concludes that multi-option strategies to achieve flexible long-term strategy to avoid both uranium and plutonium storage are desirable. (authors)

Despite the growing prevalence of prescription opioid dependence, longitudinal studies have not examined long-term treatment response. The current study examined outcomes over 42 months in the Prescription Opioid Addiction Treatment Study (POATS). POATS was a multi-site clinical trial lasting up to 9 months, examining different durations of buprenorphine-naloxone plus standard medical management for prescription opioid dependence, with participants randomized to receive or not receive additional opioid drug counseling. A subset of participants (N=375 of 653) enrolled in a follow-up study. Telephone interviews were administered approximately 18, 30, and 42 months after main-trial enrollment. Comparison of baseline characteristics by follow-up participation suggested few differences. At Month 42, much improvement was seen: 31.7% were abstinent from opioids and not on agonist therapy; 29.4% were receiving opioid agonist therapy, but met no symptom criteria for current opioid dependence; 7.5% were using illicit opioids while on agonist therapy; and the remaining 31.4% were using opioids without agonist therapy. Participants reporting a lifetime history of heroin use at baseline were more likely to meet DSM-IV criteria for opioid dependence at Month 42 (OR=4.56, 95% CI=1.29-16.04, popioid abstinence. Eight percent (n=27/338) used heroin for the first time during follow-up; 10.1% reported first-time injection heroin use. Long-term outcomes for those dependent on prescription opioids demonstrated clear improvement from baseline. However, a subset exhibited a worsening course, by initiating heroin use and/or injection opioid use. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

This study aimed to identify the aluminum (Al)-induced proteomes in tomato (Solanum lycopersicum, "Micro-Tom") after long-term exposure to the stress factor. Plants were treated in Magnavaca's solution (pH 4.5) supplemented with 7.5 μM Al(3+) ion activity over a 4 month period beginning at the emergence of flower buds and ending when the lower mature leaves started to turn yellow. Proteomes were identified using a 8-plex isobaric tags for relative and absolute quantification (iTRAQ) labeling strategy followed by a two-dimensional (high- and low-pH) chromatographic separation and final generation of tandem mass spectrometry (MS/MS) spectra of tryptic peptides on an LTQ-Orbitrap Elite mass spectrometer. Principal component analysis revealed that the Al-treatment had induced systemic alterations in the proteomes from roots and leaves but not seed tissues. The significantly changed root proteins were shown to have putative functions in Al(3+) ion uptake and transportation, root development, and a multitude of other cellular processes. Changes in the leaf proteome indicate that the light reaction centers of photosynthetic machinery are the primary targets of Al-induced stress. Embryo and seed-coat tissues derived from Al-treated plants were enriched with stress proteins. The biological processes involving these Al-induced proteins concur with the physiological and morphological changes, such as the disturbance of mineral homeostasis (higher contents of Al, P, and Fe and reduced contents of S, Zn, and Mn in Al-treated compared to nontreated plants) in roots and smaller sizes of roots and the whole plants. More importantly, the identified significant proteins might represent a molecular mechanism for plants to develop toward establishing the Al tolerance and adaptation mechanism over a long period of stress treatment.

2013-06-01

Full Text Available The main purpose of the article is to identify the peculiarities of a doctor personality, affecting long-term therapy in patients with cardiovascular diseases. Materials and methods: To determine the type of temperament, the presence and intensity of the syndrome of emotional burnout and capacity for empathy therapists and cardiologists were asked to fill in a number of questionnaires. Each doctor had a group of patients contacting by telephone for a year after the discharge from the hospital. During the telephone contact, the patients were asked about the continuation of their therapy recommended in the hospital, the regularity of therapy, the frequency of absence, and the assessment of a physician by the patients. Results: 35 questionnaires were suitable for interpretation. Through one year after the discharge from the hospital it was able to contact with 147 patients, 18.4% (27 of patients completely stopped the treatment by recommended drugs. Positive assessment of physicians was associated with the continuation of the therapy by recommended drugs and regularity of drug taking (p=0,03. Patients assessed physicians positively more often in cases of low level of emotional state, high level of depersonalization (cynicism and the reduction of personal accomplishment (feeling of professional inefficiency in a doctor. Conclusion: Assessment of physicians by patients is reliably and significantly influenced by continuation of long-term therapy and regularity of drug taking.

Full Text Available Ann Crawford, Sally Jewell,* Holly Mara, Laura McCatty, Regina Pelfrey The Lash Group; Frisco, TX, USA *Sally Jewell is now retired Abstract: This article discusses the many ways that nurses can address the factors that lead to treatment fatigue in patients with multiple sclerosis (MS on long-term disease-modifying therapy, ultimately helping to preserve the patient’s health and quality of life. Patients with MS on long-term therapy may suffer from treatment fatigue and poor adherence due to a variety of different factors, including difficulties with injections, anxiety/depression, financial problems, and inaccurate beliefs about the MS disease process. Because MS nurses have regular interactions with patients, they are ideally situated to help patients cope with these and other factors that may limit adherence.

Document available in abstract form only. Full text of publication follows: Long term memory of repositories is required by safety, reversibility and social expectations. Thus Andra has implemented since 2010 a long-term memory project to reinforce and diversify its current arrangements in this field, as well as to explore opportunities to extend memory keeping over thousands years. The project includes opportunity studies of dedicated facilities. The 'Ecotheque' and 'Geotheque' projects contribute to memory respectively through environmental and geological samples preservation. The options of creating (i) an archive centre for Andra's interim and permanent archives, (ii) an artist center to study the contribution of arts to memory preservation, (iii) a museum of radioactive waste disposal history and technology (radium industry..., sea disposal, current solutions...) are considered. Other studies provided by the project examine our heritage. This includes the continuity of languages and symbolic systems, the continuity of writing and engraving methods, the archaeology of landscapes (memory of the earths evolution, multi-century memory of industrial and agricultural landscapes), the archaeology practices (how might a future archaeologist be interested in our current activity?), the preservation of historical sites and industrial memory, the continuity of institutional organizations, the memory and history of science evolution as well as broad history

2018-01-01

CONTEXT: Review of the yeast Saccharomyces boulardii as a treatment option for the inflammatory bowel diseases (IBD) ulcerative colitis and Crohn's disease. OBJECTIVE: IBD is caused by an inappropriate immune response to gut microbiota. Treatment options could therefore be prebiotics, probiotics......, antibiotics and/or fecal transplant. In this review, we have looked at the evidence for the yeast S. boulardii as a treatment option. MATERIAL AND METHODS: Searches in PubMed and the Cochrane Library with the MeSH words 'Saccharomyces boulardii AND IBD', 'Saccharomyces boulardii AND Inflammatory Bowel Disease....... Saccharomyces boulardii is, however, a plausible treatment option in the future, but more placebo-controlled clinical studies on both patients with ulcerative colitis and Crohn's disease are needed....

The possible use of options pricing theory for evaluating long-term capital investments is discussed. Using the Black and Scholes option pricing model, five variables were evaluated for a hypothetical oil sands project. These variables are: stock price as determined by the earning power of the company; exercise price which equals the investment cost of the project; price standard deviation which is assumed to be 50%; the length of time for which the company will maintain its option to invest in the project, and finally the risk free rate which is approximately equal to the yield in long term government securities. A sensitivity analysis on these variables can provide management with information on how best to influence the option value. A more in-depth analysis could provide valuable information about strategic choice for large projects. 5 refs., 3 figs

Haloperidol for long-term aggression in psychosis.

Science.gov (United States)

Khushu, Abha; Powney, Melanie J

2016-11-27

Psychotic disorders can lead some people to become agitated. Characterised by restlessness, excitability and irritability, this can result in verbal and physically aggressive behaviour - and both can be prolonged. Aggression within the psychiatric setting imposes a significant challenge to clinicians and risk to service users; it is a frequent cause for admission to inpatient facilities. If people continue to be aggressive it can lengthen hospitalisation. Haloperidol is used to treat people with long-term aggression. To examine whether haloperidol alone, administered orally, intramuscularly or intravenously, is an effective treatment for long-term/persistent aggression in psychosis. We searched the Cochrane Schizophrenia Group Trials Register (July 2011 and April 2015). We included randomised controlled trials (RCT) or double blind trials (implying randomisation) with useable data comparing haloperidol with another drug or placebo for people with psychosis and long-term/persistent aggression. One review author (AK) extracted data. For dichotomous data, one review author (AK) calculated risk ratios (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis based on a fixed-effect model. One review author (AK) assessed risk of bias for included studies and created a 'Summary of findings' table using GRADE. We have no good-quality evidence of the absolute effectiveness of haloperidol for people with long-term aggression. One study randomising 110 chronically aggressive people to three different antipsychotic drugs met the inclusion criteria. When haloperidol was compared with olanzapine or clozapine, skewed data (n=83) at high risk of bias suggested some advantage in terms of scale scores of unclear clinical meaning for olanzapine/clozapine for 'total aggression'. Data were available for only one other outcome, leaving the study early. When compared with other antipsychotic drugs, people allocated to haloperidol were no more likely to leave the study

The long-term power purchase: Recovery of capacity costs

International Nuclear Information System (INIS)

Cross, P.S.

1990-01-01

As electric utilities increase their reliance on the long-term power purchase as an alternative to utility-owned generation, the appropriate rate treatment of the costs established in the purchase agreement assumes growing importance. In the November 9, 1989, issue, the authors examined the recent trend among state regulators to treat the long-term purchase in a manner similar to the addition by a utility of a new plant, including a full-scale prudence review. This installment will review recent rulings on the related issue of rate recovery of long-term capacity costs through the fuel cost adjustment clause

Abstarct: Background and purpose: Tumor recurrence after surgery for cervical carcinoma is associated with high fatality and morbidity, forming a major therapeutic challenge. This paper presents our experience with treatment of this patient group by salvage radiotherapy with curative intent. Materials and methods: Thirty-five patients with a pelvic recurrence after hysterectomy received high-dose radiotherapy. A retrospective analysis of long-term outcome and prognostic factors was performed. Results: After a median follow-up period of 12.1 years, actuarial 2-,5- and 10-year overall survival rates were 66%, 43% and 33%; disease-free survival rates were 62%, 45% and 41%, respectively. Pelvic control rates at 2-,5- and 10-years were 77%, 69% and 62%. Unfavorable prognostic factors on univariate analysis for survival were: recurrence extending to the pelvic wall versus central recurrence, early recurrence after surgery, external boost versus brachytherapy boost, low total dose and high age. Only a brachytherapy boost and a long interval between surgery and recurrence were significant on multivariate analysis. Severe complications (≥grade 3) were seen in 6 patients (17%; actuarial after 5 years, 21%). Conclusions: Salvage radiotherapy for recurrent cervical carcinoma following surgery may result in 40-50% long-term disease-free survival and an acceptable risk of severe treatment complications, even in patient with recurrences extending to the pelvic wall

Fourteen-Year Long-Term Results after Gastric Banding

Christine Stroh

2011-01-01

Full Text Available Background. Gastric banding (GB is a common bariatric procedure that is performed worldwide. Weight loss can be substantial after this procedure, but it is not sufficient in a significant portion of patients. Long-term rates for associated complications increase with every year of follow up, and only a few long-term studies have been published that examine these rates. We present our results after 14 years of postoperative follow up. Methods. Two hundred patients were operated upon form 01.02.1995 to 31.01.2009. Data collection was performed prospectively. In retrospective analysis, we analyzed weight loss, short- and long-term complications, amelioration of comorbidities and long-term outcome. Results. The mean postoperative follow up time was 94.4 months (range 2–144. The follow up rate was 83.5%. The incidence of postoperative complications for slippage was 2.5%, for pouch dilatation was 9.5%, for band migration was 5.5% and 12.0% for overall band removal. After 14 years, the reoperation rate was 30.5% with a reoperation rate of 2.2% for every year of follow up. Excess weight loss was 40.2% after 1 year, 46.3% after 2 years, 45.9% after 3 years, 41.9% after five years, 33.3% after 8 years, 30.8% after 10 years, 33.3% after 12 years and 15.6% after 14 years of follow up. Conclusion. The complication and reoperation rate after GB is high. Nevertheless, GB is still a therapeutic option in morbid obese patients, but the criteria for patient selection should be carefully evaluated.

Smoking cessation treatments are effective in men and women. However, possible sex-related differences in the outcome of these treatments remain a controversial topic. This study evaluated whether there were differences between men and women in the success of smoking cessation treatment, including gender-tailored components, in the short and long term (> 1 year). A telephone survey was carried out between September 2008 and June 2009 in smokers attended in a Smoking Cessation Clinic. All patients who have successfully completed treatment (3 months) were surveyed by telephone to determine their long-term abstinence. Those who remained abstinent were requested to attend the Smoking Cessation Clinic for biochemical validation (expired CO ≤10 ppm). The probability of remaining abstinent in the long-term was calculated using a Kaplan-Meier survival analysis. The treatment success rate at 3-months was 41.3% (538/1302) with no differences by sex 89% (479/538) among those located in the telephonic follow-up study and 47.6% (256/479) were abstinent without differences by sex (p = .519); abstinence was validated with CO less than 10 ppm in 191 of the 256 (53.9% men and 46.1% women). In the survival analysis, the probability of men and women remaining abstinent in the long-term was not significant. There are no differences by sex in the outcome of smoking cessation treatment that included gender-tailored components in the short and long term (> 1 year).

Altered regulation of Akt signaling with murine cerebral malaria, effects on long-term neuro-cognitive function, restoration with lithium treatment.

Full Text Available Neurological and cognitive impairment persist in more than 20% of cerebral malaria (CM patients long after successful anti-parasitic treatment. We recently reported that long term memory and motor coordination deficits are also present in our experimental cerebral malaria model (ECM. We also documented, in a murine model, a lack of obvious pathology or inflammation after parasite elimination, suggesting that the long-term negative neurological outcomes result from potentially reversible biochemical and physiological changes in brains of ECM mice, subsequent to acute ischemic and inflammatory processes. Here, we demonstrate for the first time that acute ECM results in significantly reduced activation of protein kinase B (PKB or Akt leading to decreased Akt phosphorylation and inhibition of the glycogen kinase synthase (GSK3β in the brains of mice infected with Plasmodium berghei ANKA (PbA compared to uninfected controls and to mice infected with the non-neurotrophic P. berghei NK65 (PbN. Though Akt activation improved to control levels after chloroquine treatment in PbA-infected mice, the addition of lithium chloride, a compound which inhibits GSK3β activity and stimulates Akt activation, induced a modest, but significant activation of Akt in the brains of infected mice when compared to uninfected controls treated with chloroquine with and without lithium. In addition, lithium significantly reversed the long-term spatial and visual memory impairment as well as the motor coordination deficits which persisted after successful anti-parasitic treatment. GSK3β inhibition was significantly increased after chloroquine treatment, both in lithium and non-lithium treated PbA-infected mice. These data indicate that acute ECM is associated with abnormalities in cell survival pathways that result in neuronal damage. Regulation of Akt/GSK3β with lithium reduces neuronal degeneration and may have neuroprotective effects in ECM. Aberrant regulation of Akt

Full Text Available Carlo Calabrese, Anna Fabbri, Giulio Di FeboDepartment of Internal Medicine and Gastroenterology, University of Bologna, ItalyAbstract: The prevalence of gastroesophageal reflux disease (GERD increases with age and elderly are more likely to develop severe disease. Older patients often complain of less severe or frequent heartburn than younger patients and they may present with atypical symptoms such as dysphagia, weight loss, or extraesophageal symptoms. Proton pump inhibitors (PPIs are central in the management of GERD and are unchallenged with regards to their efficacy. They are considered safe and more effective than histamine receptor antagonists for healing esophagitis and for preventing its recurrence using a long term maintenance treatment. PPI have minimal side effects and few slight drug interactions and are considered safe for long term treatment. Pantoprazole is significantly effective both for acute and long-term treatment with excellent control of relapse and symptoms. It is well tolerated even for long-term therapy and its tolerability is optimal. Pantoprazole shows to have minimal interactions with other drugs because of a lower affinity for cytocrome P450 than older PPIs. Although the majority of elderly has concomitant illnesses and receive other drugs, this does not adversely effect the efficacy of pantoprazole because of its pharmacokinetics, which are independent of patient age. Clinical practice suggests that a low dose maintenance of PPIs should be used in older patients with GERD.Keywords: GERD, long-term management, pantoprazole, safety, efficacy, tolerability

Objective: To assess the mid-term to long-term results of interventional devascularization in the treatment of upper gastrointestinal hemorrhage in patients with portal hypertension. Methods: Interventional devascularization was performed in 49 patients with upper gastrointestinal hemorrhage due to portal hypertension caused by cirrhosis. The patients were followed up for 6-36 months after the procedure. The recurrence of bleeding, postoperative complications and outcome. were observed and analyzed. Results: The technical success rate was 98.0% (48 / 49) and the mortality was 2%. The re-bleeding occurrence rate at 1, 6, 12, 24 and 36 months was 0%, 2.1%, 12.5%, 24.5% and 27.9%, respectively. The causes of re-bleeding included re-rupture of varicose vein (25%), portal hypertensive gastropathy (58.3%) and peptic ulcer (16.7%). Conclusion: The interventional devascularization is a simple, safe and effective method for the treatment of upper gastrointestinal hemorrhage due to portal hypertension. (authors)

2012-10-01

Full Text Available Abstract Background Selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, and benzodiazepine anxiolytics are used in the US to treat generalized anxiety disorder (GAD. While benzodiazepines typically provide rapid symptomatic relief, long-term use is not recommended due to risks of dependency, sedation, falls, and accidents. Methods Using a US health insurance database, we identified all persons with GAD (ICD-9-CM diagnosis code 300.02 who began a long-term course of treatment (≥90 days with a benzodiazepine anxiolytic between 1/1/2003 and 12/31/2007, We compared healthcare utilization and costs over the six-month periods preceding and following the date of treatment initiation (“pretreatment” and “post-treatment”, respectively, and focused attention on accident-related encounters (e.g., for treatment of fractures and care received for other reasons possibly related benzodiazepine use (e.g., sedation, dizziness. Results A total of 866 patients met all study entry criteria; 25% of patients began treatment on an add-on basis (i.e., adjunctive to escitalopram, paroxetine, sertraline, or venlafaxine, while 75% of patients did not receive concomitant therapy. Mean total healthcare costs increased by $2334 between the pretreatment and post-treatment periods (from $4637 [SD=$9840] to $6971 [$17,002]; p Conclusions Healthcare costs increase in patients with GAD beginning long-term (≥90 days treatment with a benzodiazepine anxiolytic; a substantial proportion of this increase is attributable to care associated with accidents and other known sequelae of long-term benzodiazepine use.

Critical mid-term uncertainties in long-term decarbonisation pathways

2012-01-01

Over the next decade, large energy investments are required in the UK to meet growing energy service demands and legally binding emission targets under a pioneering policy agenda. These are necessary despite deep mid-term (2025–2030) uncertainties over which national policy makers have little control. We investigate the effect of two critical mid-term uncertainties on optimal near-term investment decisions using a two-stage stochastic energy system model. The results show that where future fossil fuel prices are uncertain: (i) the near term hedging strategy to 2030 differs from any one deterministic fuel price scenario and is structurally dissimilar to a simple ‘average’ of the deterministic scenarios, and (ii) multiple recourse strategies from 2030 are perturbed by path dependencies caused by hedging investments. Evaluating the uncertainty under a decarbonisation agenda shows that fossil fuel price uncertainty is very expensive at around £20 billion. The addition of novel mitigation options reduces the value of fossil fuel price uncertainty to £11 billion. Uncertain biomass import availability shows a much lower value of uncertainty at £300 million. This paper reveals the complex relationship between the flexibility of the energy system and mitigating the costs of uncertainty due to the path-dependencies caused by the long-life times of both infrastructures and generation technologies. - Highlights: ► Critical mid-term uncertainties affect near-term investments in UK energy system. ► Deterministic scenarios give conflicting near-term actions. ► Stochastic scenarios give one near-term hedging strategy. ► Technologies exhibit path dependency or flexibility. ► Fossil fuel price uncertainty is very expensive, biomass availability uncertainty is not.

2017-01-01

Atlantoaxial spondyloarthropathy most often results from rheumatoid arthritis, cancer metastasis, or basilar invagination. Dialysis-related spondyloarthropathy is a rare cause of spinal deformity and cervical myelopathy at the atlantoaxial joint. We report 2 patients on long-term hemodialysis who presented with atlantoaxial spondyloarthropathy. Two patients with end-stage renal failure presented with a history of progressively worsening neck pain, motion limitation, and gait disturbance. In both patients, radiologic findings showed a bone-destroying soft tissue mass lateral to C1 and C2, compressing the spinal cord and causing atlantoaxial instability. We performed a C1 laminectomy and C12 transarticular screw fixation and biopsied the osteolytic mass. The neck pain, hand numbness, and gait disturbance improved. Although the surgical management of these patients involves many challenges, appropriate decompression and fusion surgery is an effective treatment option. Copyright © 2016 Elsevier Inc.

Full Text Available Abstract Background This analysis of pooled data evaluates treatment outcomes of patients with schizophrenia receiving maintenance treatment with olanzapine long-acting injection (OLAI by means of a categorical approach addressing the symptomatic and functional status of patients at different times. Methods Patients were grouped into 5 categories at baseline, 6 months, and 12 months. Shifts between categories were assessed for individual patients and factors associated with improvement were analyzed. 1182 patients from 3 clinical trials were included in the current analysis. Results At baseline, 434 (36.8% patients had minimal Positive and Negative Syndrome Scale (PANSS symptoms but seriously impaired Heinrich Carpenter’s Quality of Life Scale (QLS functioning; 303 (25.6% had moderate to severe symptoms and seriously impaired function; 208 (17.6% had mild to moderate symptoms but good functioning, and 162 (13.7% had minimal symptoms and good functioning. Baseline category was significantly associated with Clinical Global Impression – Severity (CGI-S, extrapyramidal symptoms, working status, age, and number of previous episodes. The majority of all patients starting OLAI treatment maintained or improved (62% at 6 months and 52% at 12 months their symptom and functioning levels on OLAI maintenance treatment. Less than 8% of the patients showed worsening of symptoms or functioning. An improvement in category was associated with high PANSS positive and low CGI-S scores at baseline. Conclusions We present evidence that a composite assessment of schizophrenic patients including symptom severity and functioning is helpful in the evaluation of maintenance treatment outcomes. This approach could also be useful for the assessment of treatment options in clinical practice. The trials from which data are reported here were registered on clinicaltrials.gov as NCT00088491, NCT00088465, and NCT00320489.

OBJECTIVE Hydrocephalus remains one of the more common pathologies managed in pediatric neurosurgical units. Endoscopic third ventriculostomy (ETV) has an advantage over ventriculoperitoneal shunting as it enables patients to remain device free. Multiple shunt devices with various valve designs exist, with no one valve proven to be superior to another. The aim of this study was to describe the management of hydrocephalus and its long-term outcome. METHODS The authors retrospectively reviewed the medical records of all patients who had been treated for hydrocephalus at the Hôpital Necker-Enfants Malades in the period from 1985 to 1995. RESULTS Nine hundred seventy-five children had been treated for hydrocephalus. The mean follow-up was 11 ± 7.4 years (mean ± standard deviation). The most common cause of hydrocephalus was tumor related (32.3%), followed by malformative (24.5%) and inflammatory (20.9%) causes. Two hundred eighty patients underwent ETV as the first-line treatment. The procedure was effective in controlling hydrocephalus due to posterior fossa tumors and aqueductal stenosis. Six hundred ninety-five children had initial shunt insertion, with the majority receiving an Orbis-Sigma valve (OSV). The overall OSV shunt survival was 70% at 1 year, 58% at 10 years, and 49% at 20 years. The most common cause for mechanical shunt failure was obstruction (50.7%). Overall shunt survival was statistically different between the OSV and the differential-pressure valve (p = 0.009). CONCLUSIONS Endoscopic third ventriculostomy is effective in the management of childhood hydrocephalus. Its success is directly related to the underlying pathology. In the long term, the OSV has significantly higher event-free shunt survival than the classic differential-pressure valve systems.

Topical steroids are used for the treatment of primary atopic dermatitis (AD); however, their associated risk of serious complications is great due to the presence of vulnerable lesions in young children with AD. Topical calcineurin inhibitors (TCIs) are steroid-free, anti-inflammatory agents used for topical AD therapy. However, their use is prohibited in infants side effects. The 1% pimecrolimus cream displayed similar efficacy and exceptional safety compared with the 0.05% desonide cream. Metabolomics-based long-term toxicity tests effectively predicted long-term side effects using short-term clinical models. This applicable method for the functional interpretation of metabolomics data sets the foundation for future studies involving the prediction of the toxicity and systemic reactions caused by long-term medication administration.

Long-term fluoxetine treatment induces input-specific LTP and LTD impairment and structural plasticity in the CA1 hippocampal subfield.

Full Text Available Antidepressant drugs are usually administered for long time for the treatment of major depressive disorder. However, they are also prescribed in several additional psychiatric conditions as well as during long term maintenance treatments. Antidepressants induce adaptive changes in several forebrain structures which include modifications at glutamatergic synapses. We recently found that repetitive administration of the selective serotonin reuptake inhibitor fluoxetine to naϊve adult male rats induced an increase of mature, mushroom-type dendritic spines in several forebrain regions. This was associated with an increase of GluA2-containing α-amino-3-hydroxy-5-methylisoxazole-4-propionate receptors (AMPA-Rs in telencephalic postsynaptic densities. To unravel the functional significance of such a synaptic re-arrangement, we focused on glutamate neurotransmission in the hippocampus. We evaluated the effect of four weeks of treatment with 0.7 mg/kg of fluoxetine on long-term potentiation (LTP and long-term depression (LTD in the Schaffer collateral-CA1 synapses and the perforant path-CA1 synapses. Recordings in hippocampal slices revealed profound deficits in LTP and LTD at Schaffer collateral-CA1 synapses associated to increased spine density and enhanced presence of mushroom-type spines, as revealed by Golgi staining. However, the same treatment had neither an effect on spine morphology, nor on LTP and LTD at perforant path-CA1 synapses. Cobalt staining experiments revealed decreased AMPA-R Ca2+ permeability in the stratum radiatum together with increased GluA2-containing, Ca2+-impermeable AMPA-Rs. Therefore, 4 weeks of fluoxetine treatment promoted structural and functional adaptations in CA1 neurons in a pathway-specific manner that were selectively associated with impairment of activity-dependent plasticity at Schaffer collateral-CA1 synapses.

Purpose: To evaluate the short and long term effects of total lymphoid irradiation (TLI) in the treatment of allograft rejection in cardiac transplant patients. Materials and Methods: From 1986 to 1995, 48 courses of TLI were delivered to 47 patients who had received cardiac transplants at Stanford University. In 38 cases, TLI was administered for chronic, intractable allograft rejection despite conventional anti-rejection therapy, including corticosteroids, azathioprine, cyclosporine, OKT3, DHPG, RATG, and methotrexate. Ten patients received TLI prophylactically, beginning radiation between 5 and 16 days after heart transplantation. The prescribed radiation dose was 800 cGy given in 80 cGy fractions twice weekly to all major lymph node regions using mantle and inverted Y fields. Patients continued to receive all medications except azathioprine which was held during TLI to prevent severe marrow suppression. All patients were closely monitored for episodes of rejection, infection, prednisone requirements, blood counts, and complications of treatment. Post-irradiation follow up ranged from 6 months to 9.1 years with a mean of 3.1 years. Results: The actual mean dose of radiation was 730 cGy delivered over a mean of 39 calendar days. Fifty six percent of patients required treatment delay or abbreviation because of thrombocytopenia, leukopenia, infection, or unrelated problems. In patients treated for intractable rejection, the frequency of rejection dropped from 0.46 episodes/patient/month before radiation to 0.14 episodes/patient/month during TLI (p 3 during TLI (p = 0.01) and remained low at 167.6 cells/mm 3 2-4 months after treatment (p = 0.05). CD8+ lymphocytes also decreased during treatment from 233.2 to 65.8 cells/mm 3 (p = 0.003) but rose significantly above normal to 381.3 cells/mm 3 2-4 months after TLI (p 0.05). Thus, the ratio of helper/suppresser T-cells was chronically decreased. Infection rates were not significantly different before, during or after
