    Breast cancer is the most common female malignancy in many industrialized countries. Approximately one fourth of all women diagnosed with early breast cancer present with tumors that are characterized by erbB2 amplification. While the associated Her-2/neu receptor overexpression results in a high risk of relapse and poor prognosis, these tumors also represent a target for a selective monoclonal antibody therapy with trastuzumab (Herceptin). The combination of trastuzumab with chemotherapy has led to a considerable reduction of recurrences and to a significant reduction in breast cancer mortality both in the adjuvant and metastatic setting. Unfortunately, despite Her-2/neu overexpression, not all patients equally benefit from trastuzumab treatment, and almost all women with metastatic breast cancer eventually progress during antibody therapy. Moreover, trastuzumab is burdened with cardiotoxicity, thus increasing the risk of symptomatic congestive heart failure. In addition, the marginal costs for a 1 year therapy of trastuzumab-based therapy, which is currently considered to be the most effective treatment regimen in the adjuvant setting, may amount for up to US$ 40.000. Testing for erbB2 oncogene amplification by fluorescence in situ hybridization (FISH) and chromogenic in situ hybridization (CISH), respectively, and staining for Her-2/neu receptor overexpression by immunohistochemistry (IHC) represent the current standard for determining patient eligibility for trastuzumab-based therapy. However, while the negative predictive value of these assays for predicting the absence of benefit from trastuzumab-based therapy is sufficiently high, their positive predictive value remains insufficient, i.e. only a proportion of patients selected by these tests substantially benefit from trastuzumab-containing regimen. Accordingly, over the last years a number of biomarkers have been evaluated in their potential to predict response to trastuzumab-based therapies. These include

    Lane, Justin D; Ledford, Jennifer R; Gast, David L

    Occupational therapy is a field with a long-standing history of recommending and implementing interventions designed to improve the quality of life of clients with disabilities. Often, the interventions are individualized to meet the needs of this diverse group of clients in dynamic settings. Identifying effective and efficient interventions for such a diverse group of clients and settings requires a flexible research approach. Single-case experimental designs (SCEDs) allow practitioners and researchers to answer experimental questions within the context of rigorous research designs. The purpose of this article is to highlight the similarities between the mission of occupational therapy and SCEDs. Recommendations for designing single-case studies with the framework provided by the Single-Case Reporting Guideline in Behavioral Interventions are provided. In addition, common problems and proposed solutions, along with implications for practitioners and researchers, are provided. Copyright © 2017 by the American Occupational Therapy Association, Inc.

    Perihilar cholangiocarcinoma, which is a rare primary malignancy, originates from the epithelial cells of the bile duct. Usually invading the periductal tissues and the lymph nodes, perihilar cholangiocarcinoma is commonly diagnosed in the advanced stage of the disease and has a dismal prognosis. Currently, complete hepatectomy is the primary therapy for curing this disease. Perioperative assessment and available surgical procedures can be considered for achieving a negative margin resection, which is associated with long-term survival and better quality of life. For patients with unresectable cholangiocarcinoma, several palliative treatments have been demonstrated to produce a better outcome; and liver transplantation for selected patients with perihilar cholangiocarcinoma is promising and desirable. However, the role of palliative treatments and liver transplantation was controversial and requires more evidence and substantial validity from multiple institutions. In this article, we summarize the data from multiple institutions and discuss the resectability, mortality, morbidity and outcome with different approaches.

  5. Current therapy for Parkinson's disease

    Full Text Available The main goal of therapy for Parkinson's disease (PD is to correct dopamine deficiency in the nigrostriatal system. Levodopa preparations and dopamine receptor agonists (DRAs that are prescribed with regards to patient age and disease severity are mainly used now. Notwithstanding the fact that levodopa preparations are the gold standard of therapy, their long-term use gives rise to complications as motor fluctuations and drug-induced dyskinesias. The currently available DRAs are the drugs of choice for the therapy of early-stage PD as they are as effective as levodopa preparations. In extensive-stage PD, DRAs are used to enhance the therapy and correction of developed motor fluctuations and dyskinesias. Pramipexole is one of the most commonly used representatives of non-ergoline DRAs. The paper analyzes the efficacy of the medication used as both monotherapy and part of combined therapy, its effect on tremor and depression in PD. A novel extended-release formulation of pramipexole is considered separately. Both immediate- and extended-release pramipexole formulations contain the same active ingredient and have the same dopamine-receptor interaction profile, but differ in the tablet release rate of the active ingredient. The advantages of the novel formulation are its more steady-state plasma concentration and 24-hour action, which ensures continuous dopaminergic stimulation ofpostsynaptic receptors to prevent and treat already developed motor complications. The once-daily extended-release formulation of the drug makes its treatment regimen easier and patient compliance higher.

    Full Text Available Most of the electroconvulsive therapy guidelines state that severe major depression with psychotic features, manic delirium, or catatonia are conditions where there is a clear consensus favoring early electroconvulsive therapy. The decision to administer electroconvulsive therapy is based on an evaluation of the risks and benefits for the individual patient and involves a combination of factors, including psychiatric diagnosis, type and severity of symptoms, prior treatment history and response, identification of possible alternative treatment options, and consumer preference. In this review history, mechanisms of action, side effects that have been referenced in the literature and clinical experience are discussed.

    2016-07-01

    Premature ejaculation (PE) subjectively affects 20-30% of men globally. Until recently, understanding of PE was hampered by the absence of a widely accepted definition, paucity of evidence-based clinical studies, and the absence of an appropriate animal model. Here, we elaborate on the current definition of PE, its pathogenesis, currently available therapies, and future treatment prospects. Most treatments for PE are 'off-label' and include selective serotonin reuptake inhibitors (SSRIs), topical anesthetics, tramadol, and phosphodiesterase type 5 (PDE5) inhibitors. Such knowledge of the benefit and limitations of each treatment will help to direct future drug design and formulations.

    2003-01-01

    Treatment of steatorrhea by lipase supplementation therapy has become more successful in the last decade due to better understanding of the physiology and pathophysiology of the digestive process. Porcine lipase has been the therapeutic standard for several decades and will continue to be the treatment of choice in pancreatic exocrine insufficiency. Modern therapeutic concepts recommend administration of 25,000-40,000 units of porcine lipase per meal using pH-sensitive pancreatin microspheres. In case of treatment failure, the dose should be increased, compliance should be checked, and other reasons for malabsorption should be excluded. Still, in most patients, lipid digestion cannot be completely normalized by current standard therapy, and future developments are needed for optimizing treatment. In this article, pathophysiologic characteristics of pancreatic exocrine insufficiency, prerequisites for use of alternative lipase sources as well as currently available lipases of nonporcine origin, and new developments are discussed. Current literature suggests that bovine lipase products present a theoretical alternative but play no major role in the western world. Fungal lipase has inferior properties compared with conventional products. Bacterial lipase products show promising potential and offer future therapeutic alternatives. Moreover, human pancreatic lipase gene transfer and application of bioengineered human gastric lipase appear on the horizon.

    The aim of this study was to assess whether or not photodynamic therapy enhanced standard antibacterial therapy in dentistry. Photodynamic therapy when used as an adjunct to conventional periodontal therapy kills more bacteria than when conventional periodontal therapy is used alone. To address the focused question, "Does photodynamic therapy enhance killing of oral bacteria?" PubMed/MEDLINE(®) and Google Scholar databases were explored. Original human and experimental studies and studies using photodynamic therapy for killing oral bacteria were included. Letters to the Editor, historic reviews, and unpublished data were excluded. Photodynamic therapy significantly reduces periodontopathogenic bacteria including Aggregatibacter actinomycetemcomitans, Prevotella intermedia, and Porphyromonas gingivalis. Photodynamic therapy kills cariogenic bacteria (such as Streptococcus mutans and Streptococcus sanguis), bacteria associated with infected root canals, and those associated with periimplantitis. Photodynamic therapy, when used as an adjunct to conventional oral disinfection protocols, enhances standard antibacterial therapy in dentistry.

    Full Text Available This paper is a review of the current situation of the treatment of human African trypanosomiasis. The existing approved drugs are old, toxic and/or expensive. Therapeutic failures are common. Several factors may contribute to the problems of chemotherapy, including differences in the epidemiology of the disease, difficulties in the diagnosis and staging of the infection, availability, distribution and pharmacologic properties of drugs, standardization of treatment regimens, response to therapy, follow-up period, and relapses and clinical trials. The new therapeutic approaches include the development and approval of new drugs, the use of new therapeutic regimens, the study of drug combinations, and the development of new formulations.

    2012-01-01

    BACKGROUND: Hilar cholangiocarcinoma (HC) is an adeno-carcinoma of the extrahepatic biliary tree arising from the main left or right hepatic ducts or their confluence. This tumor is still considered to be difficult to treat or to cure. DATA SOURCES: We reviewed the medical literature on HC. Relevant and updated information on this tumor was analyzed in a concise and easy-to-read manner. The article is not intended to be a systematic review, but an extensive search was conducted on PubMed and MEDLINE using the keywords "hilar cholangiocarcinoma" and "Klatskin tumor" until July 2011. RESULTS: The selection and the timing of management options for patients with HC are determined by the degree of certainty of the diagnosis, the general condition of the patients, the underlying liver function and the stage of the disease. Current treatment of HC can be divided into curative and palliative treatment. For the curative treatment, local excision should only be used on small tumors which are confined to the bile duct wall and Bismuth I papillary carcinoma. Partial hepatectomy should be combined with caudate lobe resection and porta-hepatis lymph node dissection. The results of these major resections can be improved with portal vein embolization, and staging laparoscopy and laparoscopic ultrasound. The role of preoperative biliary drainage is controversial. Autotransplantation for HC gave disappointing results while the Mayo Protocol of chemoradiation for selecting patients with unresectable HC for orthotopic liver transplantation has been widely accepted. Palliative treatment included bypass surgery, endoscopic or percutaneous stenting, photodynamic therapy, intraluminal brachytherapy, and external radiation and systemic therapy. CONCLUSIONS: Adequate surgery with R0 resection should be the main goal of treatment. For patients with unresectable HC, treatment aims to improve the quality and quantity of their survival.

  13. Pharmacotherapy of erectile dysfunction: Current standards

    Directory of Open Access Journals (Sweden)

    Kew-Kim Chew

    2006-01-01

    Full Text Available Pharmacotherapy is currently the therapeutic option of choice for erectile dysfunction. Comprising mainly intracavernosal injection therapy using alprostadil or alprostadil combined with phentolamine and/or papaverine and oral phosphodiesterase-5 inhibitors, it is safe and effective if appropriately prescribed and administered. The medications in current use produce satisfactory erectile responses by enhancing cavernosal vasodilatation mainly through their ability to promote relaxation of the smooth muscle cells in the corpora cavernosa involving the synthesis and activity of nitric oxide via the cyclic guanosine monophosphate and cyclic adenosine monophosphate biochemical pathways. The main side-effects and complications of intracavernosal injections are postinjection pain, prolonged erections, priapism and penile fibrosis. There may be a variety of side-effects with phosphodiesterase-5 inhibition but these are usually inconsequential. Recent serious ill health and the need for ongoing long-acting nitrate therapy or frequent use of short-acting nitrates for angina are absolute contraindications to the use of phosphodiesterase-5 inhibitors. Caution has to be exercised in prescribing phosphodiesterase-5 inhibitors for patients with impaired renal or hepatic functions or receiving multi-drug therapy for any systemic disease. All patients presenting with erectile dysfunction should be investigated and treated for cardiovascular risk factors. They should also be counseled regarding lifestyle factors particularly healthy balanced diet, regular physical exercise and inappropriate social habits.

    Full Text Available The data on pathogenetically significant parameters that are involved in pain perception in fibromyalgia (FM patients (increased sensitivity or density of dopamine receptors D2, enhanced pain signal due to the elevated substance P level or insufficient modification of the pain signal caused by low serotonin level; allodynia phenomenon; and the psychosomatic component are reported. New classification criteria of FM and assessment of severity of the symptoms included in these criteria are presented. The changes that have taken place in therapy of FM pain over the past decade are demonstrated: less frequent use of peripheral analgesics, tricyclic antidepressants; more frequent use of serotonin reuptake inhibitors (duloxetine, milnacipran and pregabalin. The effectiveness and fair pain tolerability of pregabalin are demonstrated. The effectiveness and tolerability of duloxetine, milnacipran, and pregabalin are compared using the data of 17 randomized controlled trials.

    2011-01-01

    Full Text Available Cognitive impairments (CIs are a highly common type of neurological disorders particularly in elderly patients. Choice of a therapeutic strategy for CI is determined by the etiology of abnormalities and their degree. Measures to prevent CI progression and dementia: adequate treatment of existing cardiovascular diseases, prevention of stroke, balanced nutrition, moderate physical and intellectual exercises, and combatting overweight and low activity are of basic value in treating mild and moderate CIs. According to the data of a number of investigations, the above measures reduce the risk of dementia, including in the genetically predisposed. Pharmacotherapy for mild and moderate CIs generally comprises vasoactive, neurometabolic, and noradrenergic agents. The indication for the use of memantine and/or acetylcholinergic agents, i.e. basic therapy for the most common forms of dementia (Alzheimer's disease, Lewy body dementia, vascular, and mixed dementia, hepatic colics is severe CIs. The long-term use of memantine and/or acetylcholinergic agents alleviates the cognitive and behavioral symptoms of dementia, enhances self-dependence in patients, and prolongs their active lifetime.

    The treatment of hypogonadism in men is of great interest to both patients and providers. There are a number of testosterone formulations currently available and several additional formulations under development. In addition, there are some lesser-used alternative therapies for the management of male hypogonadism, which may have advantages for certain patient groups. The future of hypogonadism therapy may lie in the development of selective androgen receptor modulators that allow the benefits of androgens whilst minimizing unwanted side effects. PMID:28149506

    The current health system in China has evolved by embracing both traditional Chinese medicine and Western medicine.China is the only country in the world where the number of doctors is larger than the number of nurses but education programmes for other health professions like physical therapy have been slow to develop.In the case of physical therapy it was not until China won the bid for the Olympic Games that permission to establish the first physical therapy programme was granted.Since then China has undergone a period of rapid economic growth enabling many people to have a higher standard of living and improved health,but at the same time the country is faced with massive urbanization,industrialization,increasing environmental health threats,increased health disparities and an aging population.With the support of the Chinese Association of Rehabilitation Medicine,an increased investment by the Government in public health and rehabilitation and engagement of international education experts,entry-level education programmes for physical therapy have started to develop and there are now nine which are modeled,at least to some extent,on the World Confederation for Physical Therapy's international guidelines.The paper explores the development of physical therapy education in China and discusses possible options for the way forward so that as the demand for physical therapy to service 1.4 billion people grows,the profession is prepared and the standards expected of the entry-level physical therapist will not be compromised.

    2016-01-01

    Neuromyelitis optica (NMO) is an autoimmune demyelinating disease that mainly affects the optic nerve and spinal cord, potentialy resulting in blindness and paralysis. Once thought to be a clinical variant of multiple sclerosis, NMO is currently considered as a different disease with its own features due to the identiifcation of a speciifc autoantibody against aquaporin 4. Given the high risk of disability, treatment should be launched once the diagnosis is established. Evidence from clinical practice showed that traditional immunosuppressive agents affecting the function of T and B cels could attenuate disease exacerbation. Recently, with better understanding pathogenesis of NMO, increasing bodies of novel therapies and therapeutic targets have been discovered. In this review, the authors discuss the current strategies of treating NMO in details and brielfy introduce the potential therapies in future.

    2017-05-01

    Intrahepatic cholangiocarcinoma (iCCA) is a malignancy with an increasing incidence and a high-case fatality. While surgery offers the best hope at long-term survival, only one-third of tumors are amenable to surgical resection at the time of the diagnosis. Unfortunately, conventional chemotherapy offers limited survival benefit in the management of unresectable or metastatic disease. Recent advances in understanding the molecular pathogenesis of iCCA and the use of next-generation sequencing techniques have provided a chance to identify 'target-able' molecular aberrations. These novel molecular therapies offer the promise to personalize therapy for patients with iCCA and, in turn, improve the outcomes of patients. Area covered: We herein review the current management options for iCCA with a focus on defining both established and emerging therapies. Expert commentary: Surgical resection remains as an only hope for cure in iCCA patients. However, frequently the diagnosis is delayed till advanced stages when surgery cannot be offered; signifying the urge for specific diagnostic tumor biomarkers and targeted therapies. New advances in genomic profiling have contributed to a better understanding of the landscape of molecular alterations in iCCA and offer hope for the development of novel diagnostic biomarkers and targeted therapies.

    2011-01-01

    The introduction of the Duke criteria and transesophageal echocardiography has improved early recognition of infective endocarditis but patients are still at high risk for severe morbidity or death. Whether an exclusively antibiotic regimen is superior to surgical intervention is subject to ongoing debate. Current guidelines indicate when surgery is the preferred treatment, but decisions are often based on physician preferences. Surgery has shown to decrease the risk of short-term mortality in patients who present with specific symptoms or microorganisms; nevertheless even then it often remains unclear when surgery should be performed. In this review we i) systematically reviewed the current literature comparing medical to surgical therapy to evaluate if surgery is the preferred option, ii) performed a meta-analysis of studies reporting propensity matched analyses, and iii), briefly summarized the current indications for surgery.

    2014-06-01

    The purpose of this article is to review the current therapy of Addison's disease and to highlight recent developments in this field. Conventional steroid replacement for Addison's disease consists of twice or three-times daily oral hydrocortisone and once-daily fludrocortisone; however, new treatment modalities such as modified-released hydrocortisone and continuous subcutaneous hydrocortisone infusion have recently been developed. These offer the potential for closer simulation of the physiological serum cortisol rhythm. Two studies have also looked at modifying the natural history of adrenal failure using adrenocorticotropic hormone (ACTH) stimulation and immunomodulatory therapies, leading to the concept of residual adrenal function in some Addison's disease patients. Following more than 60 years with no significant innovation in the management of Addison's disease, these new approaches hold promise for improved patient health and better quality of life in the future.

    The goal of this review is to evaluate the management options for achondroplasia, the most common non-lethal skeletal dysplasia. This disease is characterized by short stature and a variety of complications, some of which can be quite severe. Despite several attempts to standardize care, there is still no widely accepted consensus. This is in part due to absence of concrete data on the incidence of sudden unexplained death in infants with achondroplasia and the best investigation for ascertaining which individuals could benefit from foramen magnum decompression surgery. In this review, we identify the different options of care and management for the various orthopedic, neurologic, and respiratory complications. In parallel, several innovative or drug repositioning therapies are being investigated that would restore bone growth but may also prevent complications.

    Treatment of systemic sclerosis (scleroderma) presents a challenge to both the patient and the physician. Established approaches include long-term physiotherapy, disease-modifying agents such as D-penicillamine, and treatment of organ involvement. These efforts are often unsatisfactory since the results are poor. However, recent advances include treatment of Raynaud's phenomenon (plasmapheresis, stanozolol, and prostacyclin analogues), scleroderma renal crisis (angiotensin-converting enzyme inhibitors), and gastric hypomotility (cisapride). This article covers the current approaches to the disease-modifying therapy including those related to the function of collagen-producing fibroblasts, vascular alterations, and the cellular and humoral immune system, as well as treatment of involved organs.

    2011-06-01

    There have been major changes since the incidents of leukemia development in X-SCID patients after the treatments using retroviral gene therapy. Due to the risk of oncogenesis caused by retroviral insertional activation of host genes, most of the efforts focused on the lentiviral therapies. However, a relative clonal dominance was detected in a patient with β-thalassemia Major, two years after the subject received genetically modified hematopoietic stem cells using lentiviral vectors. This disappointing result of the recent clinical trial using lentiviral vector tells us that the current and most advanced vector systems does not have enough safety. In this review, various safety features that have been tried for the retroviral gene therapy are introduced and the possible new ways of improvements are discussed. Additional feature of chromatin insulators, co-transduction of a suicidal gene under the control of an inducible promoter, conditional expression of the transgene only in appropriate target cells, targeted transduction, cell type-specific expression, targeted local administration, splitting of the viral genome, and site specific insertion of retroviral vector are discussed here.

    Non-small-cell lung cancer (NSCLC) is a highly prevalent and aggressive disease. In the metastatic setting, major advances include the incorporation of immunotherapy and targeted therapies into the clinician's therapeutic armamentarium. Standard chemotherapeutic regimens have long been reported to interfere with the immune response to the tumor; conversely, antitumor immunity may add to the effects of those therapies. The aim of immunotherapy is to specifically enhance the immune response directed to the tumor. Recently, many trials addressed the role of such therapies for metastatic NSCLC treatment: ipilimumab, tremelimumab, nivolumab and lambrolizumab are immunotherapeutic agents of main interest in this field. In addition, anti-tumor vaccines, such as MAGE-A3, Tecetomide, TG4010, CIMAvax, ganglioside vaccines, tumor cell vaccines and dendritic cell vaccines, emerged as potent inducers of immune response against the tumor. The current work aims to address the most recent developments regarding these innovative immunotherapies and their implementation in the treatment of metastatic NSCLC.

  11. Standard guidelines for electrosurgery with radiofrequency current

    2009-08-01

    Full Text Available Definition: Radiofrequency (RF induces thermal destruction of the targeted tissue by an electrical current at a frequency of 0.5 MHz (RF. As the electrode tip is not heated, there is minimal thermal damage to the surrounding tissues, producing good esthetic results. Therefore, RF ablation is also known as cold ablation or "coblation." Modality: It has three modes of operation: (a Cut, (b cut and coagulate and (c coagulate. Therefore, it can be used for various purposes like incision, ablation, fulguration, shave excision and coagulation. Because of the coagulation facility, hemostasis can be achieved and operation becomes easier and faster. Indications: It is effective in treating various skin conditions like dermatosis papulosa nigra, warts, molluscum contagiosum, colloid milia, acquired junctional, compound and dermal melanocytic nevi, seborrheic keratosis, skin tags, granuloma pyogenicum, verrucous epidermal nevi, xanthelesma, rhinophyma, superficial basal cell carcinoma and telangiectasia. It can also be used for cosmetic indications such as resurfacing, earlobe repair and blepharoplasty. Anesthesia: The procedure is accomplished either under topical anesthesia eutactic mixture of local anesthetics or local injectable anesthesia, under all aseptic precautions. Procedure: While operating, only the tip of the electrode should come in contact with the tissue. Actual contact of the electrode with the tissue should be very brief in order to prevent excessive damage to the deeper tissues. This can be accomplished by moving the electrode quickly. Complications: Complications are uncommon and mainly occur due to an improper technique. The treating physician should be aware of the contraindications of the procedure as listed in these guidelines. Physician qualification: RF surgery may be performed by a dermatologist who has acquired adequate training during post-graduation or through recognized fellowships and workshops dedicated to RF surgery.

    Gene therapy is the attempt to treat diseases by means of genetic manipulation. Numerous challenges remain to be overcome before it becomes available as a safe and effective treatment option. Retroviruses and adenoviruses are among the most commonly used viral vectors in trials. The retrovirus introduces the gene it carries into the target cell genome while the adenovirus introduces the gene into the target cell nucleus without incorporating it into the target cell genome. Other viral vectors such as adeno-associated viruses, pseudotyped viruses and herpes simplex viruses, are also gaining popularity. Proposed non-viral methods for gene transfer include physical methods and the employment of chemical vectors (lipoplexes, polyplexes and inorganic nanoparticles). Recent studies have investigated potential applications of gene therapy in correcting genetic diseases, treating malignant disorders and for treatment of other diseases. Trials on gene therapy for SCID and Leber's congenital amaurosis have achieved considerable success, but the widely publicized adverse reaction in X-linked SCID patient receiving gene therapy raised concerns for safety profile of gene therapy. For that, several methods of improving safety and efficacy of gene therapy have been proposed. At present, the three main gene therapy strategies for treatment of cancer are application to oncolytic viruses, suicide-gene therapy and gene-based immunotherapy. Gendicine, the first approved anticancer drugs based on the use of gene therapy principle, is based on the use of oncolytic viruses. More evidence for wider clinical applications of gene therapy are expected as more gene therapy studies progress from the preclinical phase to clinical trial.

    Multiple sclerosis is characterized by temporal and spatial dissemination of demyelination in the central nervous system. After a discovery of disease modifying effects of interferon beta and glatiramer acetate for multiple sclerosis, many drugs for disease modifying therapy have been developed. Recently, some multicenter studies have shown that early introduction of interferon beta or glatiramer acetate into patients with clinically isolated syndrome delayed the conversion to clinically definite multiple sclerosis. Newly developed disease modifying therapies for multiple sclerosis have a specific molecular target changing an immunological reaction and many of them are oral preparations instead of injectable first line therapies. Treatment options for multiple sclerosis are increasing and it is essential for the optimal treatment choice to collect information of the long-term side effects and the combined effects with first line therapies and to acquire the knowledge of the pathomechanisms about multiple sclerosis.

    Quality technique documentation is integral to the practice of manual therapy, ensuring uniform application and reproducibility of treatment. Manual therapy techniques are described by annotations utilizing a range of acronyms, abbreviations and universal terminology based on biomechanical and anatomical concepts. The various combinations of therapist and patient generated forces utilized in a variety of weight-bearing positions, which are synonymous with Mulligan Concept, challenge practitioners existing annotational skills. An annotation framework with recording rules adapted to the Mulligan Concept is proposed in which the abbreviations incorporate established manual therapy tenets and are detailed in the following sequence of; starting position, side, joint/s, method of application, glide/s, Mulligan technique, movement (or function), whether an assistant is used, overpressure (and by whom) and numbers of repetitions or time and sets. Therapist or patient application of overpressure and utilization of treatment belts or manual techniques must be recorded to capture the complete description. The adoption of the Mulligan Concept annotation framework in this way for documentation purposes will provide uniformity and clarity of information transfer for the future purposes of teaching, clinical practice and audit for its practitioners.

  1. Current therapy for chronic cerebrovascular attack

    2015-01-01

    Full Text Available Chronic cerebrovascular attack (CCVA is a brain lesion caused by vascular factors. CCVA appears as cognitive impairments (CIs, affective (emotional disorders and focal syndromes. Treatment for CCVA requires a comprehensive approach. Effective combination therapy for CCVA involves secondary prevention of stroke and CIs; treatment of CIs; treatment of depression and other affective disorders; and neuroprotective therapy. Basic therapy for CCVA includes modification of risk factors, antihypertensive, hypolipidemic, and antithrombotic therapies. Central acetylcholinesterase inhibitors (galantamine, rivastigmine, donepezil and a reversible NMDA receptor blocker (memantine are symptomatically used at a stage of vascular and mixed dementia. There are no unique guidelines for the therapy of mild and moderate vascular nondementia-related CIs. Drug use, based on the neurochemical mechanisms underlying the development of vascular CIs, is substantiated. When choosing psychotropic agents, it is necessary to take into account the causes and clinical manifestations of neuromediator deficiency. Antidepressants are used as essential drugs. Neuroleptics and tranquilizers are additionally administered in complex-pattern syndromes, such as depression with marked anxiety. Prescription of neuroprotectors may be effective in treating both stroke and CCVA. These medicaments are most effective when a damaging factor acts, i.e. neuroprotectors should be given in a risk situation and to reduce damage. Citicoline is one of the most test drugs in a group of neuroprotectors.

    Găloiu, S; Poiană, C

    2015-01-01

    Acromegaly is a rare disease most frequently due to a GH secreting pituitary adenoma. Without an appropriate therapy, life of patients with acromegaly can be shortened with ten years. Pituitary surgery is usually the first line therapy for GH secreting pituitary adenomas. A meta-analysis proved that mortality is much lower in operated patients, even uncured, than the entire group of patients and is similar with the general population in patients with GH30% utilization of SRAs reported a lower mortality ratio than studies with lower percentages of SRA administration. Although therapy with DA has long been used in patients with acromegaly, there are no studies reporting its effect on mortality, but its efficacy is limited by the low remission rate obtained. The use of conventional external radiotherapy, although with good remission rate in time, was linked with increased mortality, mostly due to cerebrovascular diseases. Mortality in acromegaly can be reduced to expected levels from general population by using modern therapies either in monotherapy or by using multimodal approaches in experienced centers.

    2014-05-01

    After many reports of successful gene therapy studies in small and large animal models of haemophilia, we have, at last, seen the first signs of success in human patients. These very encouraging results have been achieved with the use of adeno-associated viral (AAV) vectors in patients with severe haemophilia B. Following on from these initial promising studies, there are now three ongoing trials of AAV-mediated gene transfer in haemophilia B all aiming to express the factor IX gene from the liver. Nevertheless, as discussed in the first section of this article, there are still a number of significant hurdles to overcome if haemophilia B gene therapy is to become more widely available. The second section of this article deals with the challenges relating to factor VIII gene transfer. While the recent results in haemophilia B are extremely encouraging, there is, as yet, no similar data for factor VIII gene therapy. It is widely accepted that this therapeutic target will be significantly more problematic for a variety of reasons including accommodating the larger factor VIII cDNA, achieving adequate levels of transgene expression and preventing the far more frequent complication of antifactor VIII immunity. In the final section of the article, the alternative approach of lentiviral vector-mediated gene transfer is discussed. While AAV-mediated approaches to transgene delivery have led the way in clinical haemophilia gene therapy, there are still a number of potential advantages of using an alternative delivery vehicle including the fact that ex vivo host cell transduction will avoid the likelihood of immune responses to the vector. Overall, these are exciting times for haemophilia gene therapy with the likelihood of further clinical successes in the near future. © 2014 John Wiley & Sons Ltd.

    2015-10-01

    With emerging drug delivery technologies becoming accessible, more options are expected to become available to patients with glioblastoma (GBM) in the near future. It is important for clinicians to be familiar with the underlying mechanisms and limitations of intratumoral drug delivery, and direction of recent research efforts. Tumor-adjacent brain is an extremely complex living matrix that creates challenges with normal tissue intertwining with tumor cells. For convection-enhanced delivery (CED), the role of tissue anisotropy for better predicting the biodistribution of the infusate has recently been studied. Computational predictive methods are now available to better plan CED therapy. Catheter design and placement—in addition to the agent being used—are critical components of any protocol. This paper overviews intratumoral therapies for GBM, highlighting key anatomic and physiologic perspectives, selected agents (especially immunotoxins), and some new developments such as the description of the glymphatic system.

  7. CURRENT CONCEPTS IN THERAPY OF UVEAL MELANOMA

    2015-07-01

    Full Text Available There has been significant progress made in the diagnosis and treatment of the primary uveal melanoma during the past decades and despite that, survival rate of uveal melanoma patients is still stable. Treatment options for uveal melanoma include phototherapy, brachytherapy, proton beam therapy, stereotactic radiotherapy, local resection, anti-angiogenic therapy, immunotherapy, and enucleation. Genetic analysis of tumors provides us with valuable prognostic information although effective therapies are lacking at this moment. It is not established yet whether prolonged survival is the result of treatment or whether it merely reflects earlier detection of metastases. Also, there are indications that survival after treatment of uveal melanoma probably does not depend on the method of treatment but rather on many clinical, histological and genetic risk factors. New studies are needed to provide a better understanding of of ocular treatment impact on survival in patients whose prognosis can be estimated according to the clinical stage, histological grade and genetic type. Therefore, the patients should be treated in experienced multi-disciplinary teams that must include these patients in clinical trial.

    The 1990's have brought a significant promise and the hope for a better and brighter future in the new millennium for patients with inflammatory bowel disease (I3D). A better understanding of the pathophysiology of IBD symptoms has led to newer treatnent modalities and streamlining of therapy for specific subsets of patients. ULCERATIVE COUTISThe treatnent for ulcerative colitis (UC) is aimed at modulating the inflammatory response. The drugs which are found to be effective are sulfasalazine (Azulfidine, Salazopyrin) and its 5ASA derivatives, glucocorticosteroids, immunomodulators/immunosuppressants, and other new potential drugs (Table 1).

    Summary Gallstone disease is a frequent condition throughout the world and cholesterol stones are the most frequent form in western countries. Current standard treatment of symptomatic gallstone subjects remains laparoscopic cholecystectomy. The selection of patients amenable for non-surgical, medical therapy is of key importance: a careful analysis should consider the natural history of the disease and the overall costs of therapy. Only patients with mild symptoms and small, uncalcified cholesterol gallstones in a functioning gallbladder with a patent cystic duct will be considered for oral litholysis by the hydrophilic ursodeoxycholic acid (UDCA) hopefully leading to cholesterol desaturation of bile and progressive stone dissolution. Recent studies have raised the possibility that cholesterol-lowering agents which inhibit hepatic cholesterol synthesis (statins) or intestinal cholesterol absorption (ezetimibe), or drugs acting on specific nuclear receptors involved in cholesterol and bile acid homeostasis may offer, alone or in combination, additional medical therapeutic tools for treating cholesterol gallstones. Recent perspectives on medical treatment of cholesterol gallstone disease will be discussed in this chapter. PMID:20478485

    Geographic atrophy is characterized by severe visual deficit whose etiology and pathophysiology are yet to be elucidated. As a working hypothesis, oxidative damage could trigger a chronic inflammation in Bruch's membrane-RPE-choriocapillaris complex, mostly due to complement pathway overactivation. Some individuals with mutations in the complement system and other factors have diminished capacity in the modulation of the inflammatory response, which results in cell damage and waste accumulation. This accumulation of intracellular and extracellular waste products manifests as drusen and pigmentary changes that precede the atrophy of photoreceptors, RPE, choriocapillaris with an ischemic process with decreased choroid flow. All these processes can be detected as tomographic findings and autofluorescence signals that are useful in the evaluation of patients with atrophic AMD, which helps to establish an individualized prognosis. Anti-inflammatory, antioxidant and therapies that decrease the accumulation of toxins for the preservation of the RPE cells and photoreceptors are being investigated in order to slow down the progression of this disease.

    In the last three decades there has been a noticeable trend in the redefinition of the nuclear family in Brazil. A recent increase in the rates of divorces and paradoxically also in the rates of marriages, the legalization of same-sex unions and adoption by these couples, and the phenomenon of teenage pregnancy are some of the aspects that reflect on the current Brazilian family. This review highlights these changes and describes how family therapists in Brazil are facing the challenge of assisting these families, in a continental-sized country with uneven distribution of training courses and healthcare assistance.

    2010-01-01

    Despite their potential to significantly improve health care, advanced clinical decision support (CDS) capabilities are not widely available in the clinical setting. An important reason for this limited availability of CDS capabilities is the application-specific and institution-specific nature of most current CDS implementations. Thus, a critical need for enabling CDS capabilities on a much larger scale is the development and adoption of standards that enable current and emerging CDS resources to be more effectively leveraged across multiple applications and care settings. Standards required for such effective scaling of CDS include (i) standard terminologies and information models to represent and communicate about health care data; (ii) standard approaches to representing clinical knowledge in both human-readable and machine-executable formats; and (iii) standard approaches for leveraging these knowledge resources to provide CDS capabilities across various applications and care settings. A number of standards do exist or are under development to meet these needs. However, many gaps and challenges remain, including the excessive complexity of many standards; the limited availability of easily accessible knowledge resources implemented using standard approaches; and the lack of tooling and other practical resources to enable the efficient adoption of existing standards. Thus, the future development and widespread adoption of current CDS standards will depend critically on the availability of tooling, knowledge bases, and other resources that make the adoption of CDS standards not only the right approach to take, but the cost-effective path to follow given the alternative of using a traditional, ad hoc approach to implementing CDS.

    At present, strict and lifelong gluten-free diet is the only effective treatment for celiac disease. Even small amounts of gluten (50 mg/day) can be immunogenic; therefore all food and food items and drugs that contain gluten and its derivatives must be eliminated completely from the diet. While prescribing gluten-free diet is easy; the key to the success is the dietary counseling by a nutrition specialist and maintenance of adherence to GFD by the patient. In recent times, a number of targets to halt the process of immunological injury have been explored to find out alternative treatment for celiac disease. These targets include exploration of ancient wheat if they are less immunogenic, intra-luminal digestion of gluten using prolylendopeptidases, pretreatment of whole gluten with bacterial-derived peptidase before ingestion; prevention of passage of immunogenic peptides through the tight junctions such as zonulin antagonists, Blocking of HLA-DQ2 to prevent binding of immunogenic peptides, inhibition of transglutaminase 2, immune-modulation, and induction of tolerance to gluten using gluten tolerizing vaccines, use of gluten-sequestering polymers, use of anti-inflammatory drugs (glucocorticoids, budesonides) and anti-cytokines such as anti TNF-α, and anti-interleukin-15. While many of these targets are still in the pre-clinical phase, some of them including zonulin antagonist and endopeptidases have already reached phase II and phase III clinical trials. Furthermore, while these targets appear very exciting; they at best are likely to be used as adjunctive therapy rather than a complete replacement for gluten-free diet.

    Full Text Available Cognitive behavioral therapy is still one of the most important treatment modalities in social anxiety disorder with a high level of evidence. However, some patients do not fully benefit from these therapies and this fact leads to ongoing search for new approaches. This paper reviews use of cognitive behavioral therapy in social anxiety disorder studies and discusses related updated concepts. The frequent use of computer-assisted therapy for most of recent studies was found noteworthy. Recent studies regarding social anxiety disorder focused on concepts such as attention bias, biased information processing, attention training, judgment biases, internet-based cognitive behavioral therapies and social mishap exposure. Internet-based cognitive-behavioral therapy seemed to be a good option for people who were unable to access face to face treatment.

    2016-01-01

    Full Text Available Acute ischemic stroke continues to be a major cause of permanent disability and death worldwide. Outcomes are particularly poor in patients presenting with large vessel occlusive disease with resultant ischemia and tissue injury in large and eloquent territories. Intravenous thrombolysis has been the mainstay of medical therapy, however treatment is limited to a subset of patients and many patients continue to have poor outcomes. Three trials in 2013 investigating the benefit of intra-arterial therapy failed to demonstrate benefit over medical therapy alone. More recently, five trials in 2015 were completed demonstrating superior outcomes with intra-arterial therapy with improved results attributed to higher and faster rates of recanalization in a select patient population. These trials have introduced a new standard of care in the management of acute ischemic stroke patients.

    Angina pectoris is the consequence of an inequality between the demand and supply of blood to the heart. Angina manifests itself as chest pain or discomfort and is a common complaint of patients in the hospital and in the clinic. There are, in fact, roughly half a million new cases of angina per year. Chest pain, while having many etiologies, is generally considered to be most lethal when related to a cardiac cause. In this review, the authors outline the current medical and surgical therapies that are used in the management of angina. Highlights of the various clinical trials that have assisted in the investigation of these therapies are summarized also. Then, the authors provide a focused review of the novel therapy options for angina that are currently being explored. From new medical treatments to revised surgical techniques to the discovery of stem cell therapy, many innovative options are being investigated for the treatment of angina.

    Radiotherapy for the treatment of prostate cancer has been extensively explored in the past. Along with the comprehensive understanding of the biology of prostate cancer and rapid advances in terms of technology, the outcome of treatment for the patients with prostate cancer has improved. The authors review radiotherapy as the primary treatment for the disease, with particular emphasis on the technological advances from both the radiobiological and radiophysics aspects. Nonconventional fractionated irradiation like hyper- or hypo-fractionation has been implemented in the clinic, the final results still need to be confirmed in the future. Technological advances like IMRT, IGRT,in the last two decades have significantly improved the delivery of external radiotherapy to the prostate. This has resulted in an overall increase in the total dose that can be safely delivered to the prostate, which has led to modest improvements in the biochemical outcome. However, establishing the standard therapy for prostate cancer remains controversial. It is hoped that the next decades will bring continued advances in the development of biologicals that will further improve current clinical outcomes.

    Bacterial vaginosis (BV) is the most common genital tract infection in women during their reproductive years and it has been associated with serious health complications, such as preterm delivery and acquisition or transmission of several sexually transmitted agents. BV is characterized by a reduction of beneficial lactobacilli and a significant increase in number of anaerobic bacteria, including Gardnerella vaginalis, Atopobium vaginae, Mobiluncus spp., Bacteroides spp. and Prevotella spp.. Being polymicrobial in nature, BV etiology remains unclear. However, it is certain that BV involves the presence of a thick vaginal multi-species biofilm, where G. vaginalis is the predominant species. Similar to what happens in many other biofilm-related infections, standard antibiotics, like metronidazole, are unable to fully eradicate the vaginal biofilm, which can explain the high recurrence rates of BV. Furthermore, antibiotic therapy can also cause a negative impact on the healthy vaginal microflora. These issues sparked the interest in developing alternative therapeutic strategies. This review provides a quick synopsis of the currently approved and available antibiotics for BV treatment while presenting an overview of novel strategies that are being explored for the treatment of this disorder, with special focus on natural compounds that are able to overcome biofilm-associated antibiotic resistance.

    The number of patients treated by proton beam therapy in Japan since 2000 has increased; in 2016, 11 proton facilities were available to treat patients. Notably, proton beam therapy is very useful for pediatric cancer; since the pediatric radiation dose to normal tissues should be reduced as much as possible because of the effect of radiation on growth, intellectual development, endocrine organ function and secondary cancer development. Hepatocellular carcinoma is common in Asia, and most of the studies of proton beam therapy for liver cancer have been reported by Japanese investigators. Proton beam therapy is also a standard treatment for nasal and paranasal lesions and lesions at the base of the skull, because the radiation dose to critical organs such as the eyes, optic nerves and central nervous system can be reduced with proton beam therapy. For prostate cancer, comparative studies that address adverse effects, safety, patient quality of life and socioeconomic issues should be performed to determine the appropriate use of proton beam therapy for prostate cancer. Regarding new proton beam therapy applications, experience with proton beam therapy combined with chemotherapy is limited, although favorable outcomes have been recently reported for locally advanced lung cancer, esophageal cancer and pancreatic cancer. Therefore, 'chemoproton' therapy appears to be a very attractive field for further clinical investigations. In conclusion, there are cost issues and considerations regarding national insurance for the use of proton beam therapy in Japan. Further studies and discussions are needed to address the use of proton beam therapy for several types of cancers, and for maintaining the quality of life of patients while retaining a high cure rate.

    2016-01-01

    Over the decades, pharmaceutical treatments, particularly dopaminergic (DAergic) drugs have been considered as the main therapy against motor symptoms of Parkinson's disease (PD). It is proposed that DAergic drugs in combination with other medications, such as monoamine oxidase type B inhibitors, catechol-O-methyl transferase inhibitors, anticholinergics and other newly developed non-DAergic drugs can make a better control of motor symptoms or alleviate levodopa-induced motor complications. Moreover, non-motor symptoms of PD, such as cognitive, neuropsychiatric, sleep, autonomic and sensory disturbances caused by intrinsic PD pathology or drug-induced side effects, are gaining increasing attention and urgently need to be taken care of due to their impact on quality of life. Currently, neuroprotective therapies have been investigated extensively in pre-clinical studies, and some of them have been subjected to clinical trials. Furthermore, non-pharmaceutical treatments, including deep brain stimulation (DBS), gene therapy, cell replacement therapy and some complementary managements, such as Tai chi, Yoga, traditional herbs and molecular targeted therapies have also been considered as effective alternative therapies to classical pharmaceutics. This review will provide us updated information regarding the current drugs and non-drugs therapies for PD.

  12. Individualized Low-Amplitude Seizure Therapy: Minimizing Current for Electroconvulsive Therapy and Magnetic Seizure Therapy

    Electroconvulsive therapy (ECT) at conventional current amplitudes (800–900 mA) is highly effective but carries the risk of cognitive side effects. Lowering and individualizing the current amplitude may reduce side effects by virtue of a less intense and more focal electric field exposure in the brain, but this aspect of ECT dosing is largely unexplored. Magnetic seizure therapy (MST) induces a weaker and more focal electric field than ECT; however, the pulse amplitude is not individualized and the minimum amplitude required to induce a seizure is unknown. We titrated the amplitude of long stimulus trains (500 pulses) as a means of determining the minimum current amplitude required to induce a seizure with ECT (bilateral, right unilateral, bifrontal, and frontomedial electrode placements) and MST (round coil on vertex) in nonhuman primates. Furthermore, we investigated a novel method of predicting this amplitude-titrated seizure threshold (ST) by a non-convulsive measurement of motor threshold (MT) using single pulses delivered through the ECT electrodes or MST coil. Average STs were substantially lower than conventional pulse amplitudes (112–174 mA for ECT and 37.4% of maximum device amplitude for MST). ST was more variable in ECT than in MST. MT explained 63% of the ST variance and is hence the strongest known predictor of ST. These results indicate that seizures can be induced with less intense electric fields than conventional ECT that may be safer; efficacy and side effects should be evaluated in clinical studies. MT measurement could be a faster and safer alternative to empirical ST titration for ECT and MST. PMID:25920013

    Ipsilateral occlusive or embolizing carotid artery stenoses are found in 20-30% of all cases of ischemic stroke. Several randomized studies revealed endarterectomy to be the gold standard in the therapy of severe symptomatic (NASCET, ESCT) and to some extent of asymptomatic carotid stenoses (ACAS, ACST). Stent angioplasty has been established as an alternative therapeutic option although non-inferiority of this procedure has not yet been proven. We provide an overview of both procedures as well of the state of current trials. (orig.)

    Liver diseases are a major health problem worldwide since they usually represent the main causes of death in most countries, causing excessive costs to public health systems. Nowadays, there are no efficient current therapies for most hepatic diseases and liver transplant is infrequent due to the availability of organs, cost and risk of transplant rejection. Therefore, alternative therapies for liver diseases have been developed, including cell-based therapies. Stem cells (SCs) are characterized by their self-renewing capacity, unlimited proliferation and differentiation under certain conditions into tissue- or organ-specific cells with special functions. Cell-based therapies for liver diseases have been successful in experimental models, showing anti-inflammatory, antifibrogenic and regenerative effects. Nowadays, clinical trials using SCs for liver pathologies are increasing in number, and those that have reached publication have achieved favorable effects, encouraging us to think that SCs will have a potential clinical use in a short time.

  15. Clinical Challenges to Current Molecularly Targeted Therapies in Lung Cancer.

    Lung cancer is difficult to treat with a poor prognosis and a five year survival of 15%. Current molecularly targeted therapies are initially effective in non-small cell lung cancer (NSCLC) patients; however, they are plagued with difficulties including induced resistance and small therapeutically responsive populations. This mini review describes the mechanism of resistance to several molecularly targeted therapies which are currently being used to treat NSCLC. The major targets discussed are c-Met, EGFR, HER2, ALK, VEGFR, and BRAF. The first generation tyrosine kinase inhibitors (TKIs) resulted in resistance; however, second and third generation TKIs are being developed, which are generally more efficacious and have potential to treat NSCLC patients with resistance to first generation TKIs. Combination therapies could also be effective in preventing TKI resistance in NSCLC patients.

    Hernell, Olle

    2012-01-01

    Foods intended specifically for infants and young children are considered under European community law and are defined in specific commission directives. In principal, these directives conclude that such foods must be safe, have a special composition, be distinguishable from normal foods, be suitable for fulfilling particular nutritional requirements, and should, when marketed, indicate such suitability. Since infant formulas are intended as the sole source of nutrition during the first months of life, their nutritional adequacy and safety are particularly strictly regulated. The Scientific Committee on Food report from 2003, on which the current commission directive is based, makes clear recommendations on how benefits, suitability, and safety of modifications beyond established standards should be documented and evaluated. These principles resulted in part from a workshop on characterization of infant food modifications in the EU and two position papers by the European Society for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). These papers are reviewed below.

    2015-03-01

    Prospective randomized trials and meta-analyses established concurrent radiochemotherapy (RT-CHT) as standard treatment approach in patients with inoperable, locally advanced (stage IIIA and B) non-small-cell lung cancer (NSCLC). In patients with either clinically (c) or pathologically (p) staged disease (stage IIIA), including those with pN2 disease, trimodal therapy was also frequently practiced in the past and is currently still advocated by large cooperative groups and organizations. Similarly, consolidation CHT provided after concurrent RT-CHT was suggested to be feasible and effective in inoperable stage III NSCLC. Contrasting these practices and suggestions, there is no evidence that trimodal therapy in stage IIIA (clinically or pathologically staged) or consolidation CHT in inoperable stage III NSCLC plays any role in its treatment. In both cases, evidence clearly demonstrates that concurrent RT-CHT is of similar efficacy and less toxic, and it should be considered a standard treatment option for all patients with stage III NSCLC.

    Full Text Available Alicia Cecile Borderé, Jo Lambert, Nanny van GeelUniversity Hospital of Ghent, Department of Dermatology, Ghent, BelgiumAbstract: Vitiligo is an acquired cutaneous disorder of pigmentation, with an incidence of 0.5% to 2% worldwide. There are three major hypotheses for the pathogenesis of vitiligo that are not exclusive of each other: biochemical/cytotoxic, neural and autoimmune. Recent data provide strong evidence supporting an autoimmune pathogenesis of vitiligo. As vitiligo can have a major effect on quality of life, treatment can be considered and should preferably begin early when the disease is active. Current treatment modalities are directed towards stopping progression of the disease and achieving repigmentation. Therapies include corticosteroids, topical immunomodulators, photo(chemotherapy, surgery, combination therapies and depigmentation of normally pigmented skin. Topical class 3 corticosteroids can be used for localized vitiligo. The use of topical immunomodulators (TIMs in vitiligo seems to be equally effective as topical steroids, especially when used in the face and neck region. In photo(chemotherapy, narrowband ultraviolet-B therapy (NB-UVB seems to be superior to psoralen ultraviolet-A therapy (PUVA and broadband UVB. In surgical techniques, split-thickness grafting and epidermal blister grafting were shown to be effective methods, although the non-cultured epidermal suspension technique has many advantages and seems to be a promising development. Depigmentation therapy can be considered if vitiligo affects more than 60% to 80% of the body. Complementary therapies such as Polypodium leucotomos show promising results in combination with UVB therapy. No causative treatment for vitiligo is currently available. More randomized controlled trials on the treatment of vitiligo are necessary.Keywords: vitiligo, non-surgical treatment, surgical treatment

    Helicobacter pylori has been implicated in the formation of chronic gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue lymphoma and gastric cancer. Eradication of H. Pylori has been recommended as treatment and prevention for these complications. This review is based on a search of Medline, the Cochrane Database of Systemic Reviews, and citation lists of relevant publications. Subject heading and key words used include H. Pylori, current treatment and emerging therapy. Only articles in English were included. There has been a substantial decline in the H. pylori eradication rates over the years, despite the use of proton pump inhibitor and bismuth salts for triple and quadruple therapies respectively. The reasons for eradication failure are diverse, among them, antibiotic resistance is an important factor in the treatment failure. Primary resistance to clarithromycin or metronidazole significantly affects the efficacy of eradication therapy. This has led to the introduction of second line, third line "rescue," and sequential therapies for resistant cases. Subsequently, new antibiotic combinations with proton-pump inhibitors and bismuth salts are being studied in the last decade, to find out the antibiotics that are capable of increasing the eradication rates. Some of these antibiotics include Levofloxacin, Doxycycline, Rifaximin, Rifampicin, Furazolidone based therapies. Studies are ongoing to determine the efficacy of Lactoferrin based therapy.

    Gene therapy provides the possibility of long term treatment for the severest of congenital disorders. In this review we will examine the recent advances in gene therapy for genodermatoses. Congenital diseases of the skin exhibit a wide range of severity and underlying causes and there are many possible therapeutic avenues. Gene therapy approaches can follow three paths-in vivo, ex vivo and fetal gene therapy, though the later is currently theoretical only it can provide potential results for even the most severe congenital diseases. All approaches utilize the many different vector systems available, including viral and the emerging use of non- viral integrating vectors. In addition, the use of RNAi based techniques to prevent dominant mutant protein expression has been explored as a therapy for specific dominant disorders such as keratin mutation disorders. Progress has been rapid in the past few years with some initial successful clinical trials reported. However, there are still some issues surrounding long term expression, transgene sustainability and safety issues that need to be addressed to further shift from experimental to clinically therapeutic applications. With the continuing development, merger and refinement of existing techniques there is an ever increasing likelihood of gene therapies becoming available for the more severe genodermatoses within the next decade or shortly thereafter.

    Yttrium-90 (Y90) microsphere therapy, a form of radiation therapy, is an increasingly popular option for care of patients with liver metastases or unresectable hepatocellular carcinoma. The therapy directly delivers Y90 microspheres via the hepatic artery to disease sites. Following delivery, a vast majority of microspheres preferentially lodge in the capillary vessels due to their embolic size and targeted trans-arterial delivery – depositing up to 90% of its energy in the first 5 mm of tissue. There have been a number of advances in tomographic imaging within both interventional radiology and nuclear medicine that has advanced therapy planning techniques. Quantitative imaging of Y90 microsphere distribution post-therapy has also seen innovations that have led to improvements in tumor dosimetry and characterization of tumor response. A review of current trends and recent innovation in Y90 microsphere therapies will be presented. Learning Objectives: To present the imaging requirements for Y90 microsphere therapy planning To explain the standard dosimetry models used in Y90 microsphere therapy planning To report on advances in imaging for therapy planning and posttherapy assessment of tumor dosimetry and response.

    Augmented reality (AR) has emerged from research laboratories and is now being accepted in other domains as an attractive way of visualizing information. Before AR can be used in the mass market, there are a number of obstacles that need to be overcome. Several of these can be overcome by adopting open standards. A global grassroots community seeking open, interoperable AR content and experiences began to take shape in early 2010. This community is working collaboratively to reduce the barriers to the flow of data from content provider to AR end user. Standards development organizations and industry groups that provide open interfaces for AR meet regularly to provide updates, identify complementary work, and seek harmonization. The community also identifies deployer and implementer needs, communicates requirements, and discusses emerging challenges that could be resolved with standards. In this article, we describe current activities in international standards-development organizations. We summarize the AR standards gap analysis and shed light on special considerations for using standards in mobile AR.

    2015-01-01

    Osteoarthritis (OA) is a painful chronic condition with a significant impact on quality of life. The societal burden imposed by OA is increasing in parallel with the aging population; however, no therapies have demonstrated efficacy in preventing the progression of this degenerative joint disease. Current mainstays of therapy include activity modification, conservative pain management strategies, weight loss, and if necessary, replacement of the affected joint. Mesenchymal stem cells (MSCs) are a multipotent endogenous population of progenitors capable of differentiation to musculoskeletal tissues. MSCs have a well-documented immunomodulatory role, managing the inflammatory response primarily through paracrine signaling. Given these properties, MSCs have been proposed as a potential regenerative cell therapy source for patients with OA. Research efforts are focused on determining the ideal source for derivation, as MSCs are native to several tissues. Furthermore, optimizing the mode of delivery remains a challenge both for appropriate localization of MSCs and for directed guidance toward stemming the local inflammatory process and initiating a regenerative response. Scaffolds and matrices with growth factor adjuvants may prove critical in this effort. The purpose of this review is to summarize the current state of MSC-based therapeutics for OA and discuss potential barriers that must be overcome for successful implementation of cell-based therapy as a routine treatment strategy in orthopedics.

    Familial hypercholesterolemia (FH) is a genetic disorder characterized by significantly elevated low-density lipoprotein cholesterol (LDL-C) concentrations that result from mutations of the LDL receptor, apolipoprotein B (apo B-100), and proprotein convertase subtilisin/kexin type 9 (PCSK9). Early and aggressive treatment can prevent premature atherosclerotic cardiovascular disease in these high-risk patients. Given that the cardiovascular consequences of FH are similar to typical hypercholesterolemia, traditional therapies are utilized to decrease LDL-C levels. Patients with FH should receive statins as first-line treatment; high-potency statins at high doses are often required. Despite the use of statins, additional treatments are often necessary to achieve appropriate LDL-C lowering in this patient population. Novel drug therapies that target the pathophysiologic defects of the condition are continuously emerging. Contemporary therapies including mipomersen (Kynamro, Genzyme), an oligonucleotide inhibitor of apo B-100 synthesis; lomitapide (Juxtapid, Aegerion), a microsomal triglyceride transfer protein inhibitor; and alirocumab (Praluent, Sanofi-Aventis/Regeneron) and evolocumab (Repatha, Amgen), PCSK9 inhibitors, are currently approved by the U.S. Food and Drug Administration for use in FH. This review highlights traditional as well as emerging contemporary therapies with supporting clinical data to evaluate current recommendations and discuss the future direction of FH management.

    Here we review the recent literature on Hemophilia gene transfer/therapy. Gene therapy is one of several new technologies being developed as a treatment for bleeding disorders. We will discuss current and pending clinical efforts and attempt to relate how the field is trending. In doing so, we will focus on the use of recombinant Adeno-associated viral (rAAV) vector-mediated gene transfer since all currently active trials are using this vector. Recent exciting results embody nearly 20 years of preclinical and translational research. After several early clinical attempts, therapeutic factor levels that can now be achieved reflect several modifications of the original vectors. Patterns of results are slowly starting to emerge as different AAV vectors are being tested. As with any new technology, there are drawbacks, and the potential for immune/inflammatory and oncogenic risks have emerged and will be discussed.

    2007-06-01

    Laser therapy, using low-energy laser radiation, is being more and more applied. The most applied technology is transcutaneous radiation of tissues by laser radiation. Originally, a direct action on a pathological site was mostly used, but recently more attention is given to reflexogenic areas, acupuncture points, and endocrine organ projection sites. The development of light-conductive engineering made it possible to practically apply intraorgan laser therapy. This technology is widely spread in gynecology, otorhinolaryngology, urology, gastroenterology, etc. Close to it are different versions of intratissue laser therapy (intraosteal, periosteal, myofascial). A special kind of laser therapy is laser hemotherapy. Depending on the techniques and protocol of its application, there are extracorporeal, intravascular, and supravenous ways of action. According to our comparative investigations, supravenous hemotherapy by its therapeutic efficacy and major medicinal effects can be well compared with intravascular laser hemotherapy. With good prospects and efficiency is laser therapy as a combination of laser and other physical factors. Magnetolaser therapy has been scientifically substantiated and practically applied so far. Theoretically and experimentally substantiated is a combined application of laser radiation and physical factors such as ultrasound, direct current field, vacuum, cryotherapy, etc. Experimental research and few so far clinical observations are indicative of prospects of a complex application of laser radiation and drugs. To improve light absorption, laser radiation is combined with different dyes. Photodynamic therapy, originally used in oncology, is applied today in treating different diseases. We showed a possibility of using a number of drugs possessing simultaneously photosensitizing properties to this end. Laser radiation significantly influences pharmacokinetics and pharmacodynamics of drugs, which gives reason to practically implement laser

    Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in infancy and childhood. Approximately 20 % of patients with JIA suffer from the polyarticular form of the disease, which causes a substantial disease burden and long-term sequelae. Therapeutic approaches have used steroids and conventional disease modifying antirheumatic drugs (DMARD) but over the last decade new drugs have become available for the treatment of JIA, in particular biologic DMARD. This article summarizes the current therapy options for polyarticular JIA.

    Full Text Available Cody C Wyles,1 Matthew T Houdek,2 Atta Behfar,3 Rafael J Sierra,21Mayo Medical School, 2Department of Orthopedic Surgery, 3Division of Cardiovascular Diseases, Mayo Clinic, Rochester, MN, USAAbstract: Osteoarthritis (OA is a painful chronic condition with a significant impact on quality of life. The societal burden imposed by OA is increasing in parallel with the aging population; however, no therapies have demonstrated efficacy in preventing the progression of this degenerative joint disease. Current mainstays of therapy include activity modification, conservative pain management strategies, weight loss, and if necessary, replacement of the affected joint. Mesenchymal stem cells (MSCs are a multipotent endogenous population of progenitors capable of differentiation to musculoskeletal tissues. MSCs have a well-documented immunomodulatory role, managing the inflammatory response primarily through paracrine signaling. Given these properties, MSCs have been proposed as a potential regenerative cell therapy source for patients with OA. Research efforts are focused on determining the ideal source for derivation, as MSCs are native to several tissues. Furthermore, optimizing the mode of delivery remains a challenge both for appropriate localization of MSCs and for directed guidance toward stemming the local inflammatory process and initiating a regenerative response. Scaffolds and matrices with growth factor adjuvants may prove critical in this effort. The purpose of this review is to summarize the current state of MSC-based therapeutics for OA and discuss potential barriers that must be overcome for successful implementation of cell-based therapy as a routine treatment strategy in orthopedics.Keywords: mesenchymal stem cell, osteoarthritis, treatment, regenerative medicine, cell therapy

    Hepatic diseases, like viral hepatitis, autoimmune hepatitis, hereditary hemochromatosis, non-alcoholic fatty liver disease (NAFLD) and Wilson's disease, play an important role in the development of liver cirrhosis and, hence, hepatocellular carcinoma. In this review, the current treatment options and the molecular mechanisms of action of the drugs are summarized. Unfortunately, the treatment options for most of these hepatic diseases are limited. Since hepatitis B (HBV) and C (HCV) infections are the most common causes of liver cirrhosis and hepatocellular carcinoma, they are the focus of the development of new drugs. The current treatment of choice for HBV/HCV infection is an interferon-based combination therapy with oral antiviral drugs, like nucleos(t)ide analogues, which is associated with improving the therapeutic success and also preventing the development of resistances. Currently, two new protease inhibitors for HCV treatment are expected (deleobuvir, faldaprevir) and together with the promising drug, daclatasvir (NS5A-inhibitor, currently in clinical trials), adequate therapy is to be expected in due course (circumventing the requirement of interferon with its side-effects), while in contrast, efficient HBV therapeutics are still lacking. In this respect, entry inhibitors, like Myrcludex B, the lead substance of the first entry inhibitor for HBV/HDV (hepatitis D) infection, provide immense potential. The pharmacokinetics and the mechanism of action of Myrcludex B are described in detail.

    Full Text Available Past therapies for the treatment of obesity have typically involved pharmacological agents usually in combination with a calorie-controlled diet. This paper reviews the efficacy and safety of pharmacotherapies for obesity focusing on drugs approved for long-term therapy (orlistat, drugs approved for short-term use (amfepramone [diethylpropion], phentermine, recently withdrawn therapies (rimonabant, sibutamine and drugs evaluated in Phase III studies (taranabant, pramlintide, lorcaserin and tesofensine and combination therapies of topiramate plus phentermine, bupropion plus naltrexone, and bupropion plus zonisamide. No current pharmacotherapy possesses the efficacy needed to produce substantial weight loss in morbidly obese patients. Meta-analyses support a significant though modest loss in bodyweight with a mean weight difference of 4.7 kg (95% CI 4.1 to 5.3 kg for rimonabant, 4.2 kg (95% CI 3.6 to 4.8 kg for sibutramine and 2.9 kg (95% CI 2.5 to 3.2 kg for orlistat compared to placebo at ≥12 months. Of the Phase III pharmacotherapies, lorcaserin, taranabant, topiramate and bupropion with naltrexone have demonstrated significant weight loss compared to placebo at ≥12 months. Some pharmacotherapies have also demonstrated clinical benefits. Further studies are required in some populations such as younger and older people whilst the long term safety continues to be a major consideration and has led to the withdrawal of several drugs.

    Peripheral arterial disease (PAD) is a common disorder associated with a high risk of cardiovascular mortality and continues to be under-recognized. The major risk factors for PAD are similar to those for coronary and cerebrovascular disease. Management includes exercise program, pharmacologic therapy and revascularization including endovascular and surgical approach. The optimal revascularization strategy, endovascular or surgical intervention, is often debated due to the paucity of head to head randomized controlled studies. Despite significant advances in endovascular interventions resulting in increased utilization over surgical bypass, significant challenges still remain. Platelet activation and aggregation after percutaneous transluminal angioplasty of atherosclerotic arteries are important risk factors for re-occlusion/restenosis and life-threatening thrombosis following endovascular procedures. Antiplatelet agents are commonly prescribed to reduce the risk of myocardial infarction, stroke and death from cardiovascular causes in patients with PAD. Despite an abundance of data demonstrating efficacy of antiplatelet therapy in coronary artery disease and cerebrovascular disease, there is a paucity of clinical information, clinical guidelines and randomized controlled studies in the PAD population. Hence, data on antiplatelet therapy in coronary interventions is frequently extrapolated to peripheral interventions. The aim of this review article is to elucidate the current data on revascularization and the role and duration of antiplatelet and anticoagulant therapy in re-vascularized lower limb PAD patients.

    2012-01-01

    Multiple sclerosis is an autoimmune disease of the human central nervous system characterized by immune-mediated myelin and axonal damage, and chronic axonal loss attributable to the absence of myelin sheaths. There are two aspects to the treatment of MS-first, the prevention of damage by suppressing the maladaptive immune system, and second, the long-term preservation of axons by the promotion of remyelination, a regenerative process in which new axons are restored to demyelinated axons. Medicine has made significant progress in the first of these in recent years-there is an increasing number of ever more effective disease-modifying immunomodulatory interventions. However, there are currently no widely used regenerative therapies in MS. Conceptually, there are two approaches to remyelination therapy-transplantation of myelinogenic cells and promotion of endogenous remyelination mediated by myelinogenic cells present within the diseased tissue. In this chapter, in addition to describing why remyelination therapies are important, we review both these approaches, outlining their current status and future developments.

    Parkinson's disease (PD) is the second most common neurodegenerative disorder caused by the selective and progressive loss of dopaminergic neurons in the substantia nigra pars compacta. Although PD has been heavily researched, the precise etiology and pathogenesis for PD are still inconclusive. Consequently, current pharmacological treatments for PD are largely symptomatic rather than preventive and there is still no cure for this disease nowadays. Moreover, nonmotor symptoms caused by intrinsic PD pathology or side effects induced by currently used pharmacological interventions are gaining increasing attention and urgently need to be treated due to their influence on quality of life. As ancient traditional healing systems, Tai Chi, Yoga, acupuncture and natural products have long been considered as complementary or alternative therapeutic options for PD. Recently, several newly developed non-pharmacological therapeutic strategies, including deep brain stimulation, repetitive transcranial magnetic stimulation, near-infrared light, gene therapy and cell replacement therapy, have also been suggested to give benefits to relieve parkinsonian symptoms. This review will summarize and update the therapeutic potential and the most recent research progresses of these traditional and modern therapeutic options and highlight their clinical meaning for the therapy of not only PD but also other neurodegenerative diseases.

    1.1 This practice covers the use of conformable eddy-current sensors for nondestructive characterization of coatings without standardization on coated reference parts. It includes the following: (1) thickness measurement of a conductive coating on a conductive substrate, (2) detection and characterization of local regions of increased porosity of a conductive coating, and (3) measurement of thickness for nonconductive coatings on a conductive substrate or on a conductive coating. This practice includes only nonmagnetic coatings on either magnetic (μ ≠ μ0) or nonmagnetic (μ = μ0) substrates. This practice can also be used to measure the effective thickness of a process-affected zone (for example, shot peened layer for aluminum alloys, alpha case for titanium alloys). For specific types of coated parts, the user may need a more specific procedure tailored to a specific application.

    Background Owing to highly conformed dose distribution, intensity modulated radiation therapy (IMRT) has the potential to improve treatment results of radiotherapy (RT). Postoperative RT is a standard adjuvant treatment in conservative treatment of breast cancer (BC). The aim of this review is to analyze available evidence from randomized controlled trials (RCTs) on IMRT in BC, particularly in terms of reduction of side effects. Methods A literature search of the bibliographic database PubMed, from January 1990 through November 2016, was performed. Only RCTs published in English were included. Results Ten articles reporting data from 5 RCTs fulfilled the selection criteria and were included in our review. Three out of 5 studies enrolled only selected patients in terms of increased risk of toxicity. Three studies compared IMRT with standard tangential RT. One study compared the results of IMRT in the supine versus the prone position, and one study compared standard treatment with accelerated partial breast IMRT. Three studies reported reduced acute and/or late toxicity using IMRT compared with standard RT. No study reported improved quality of life. Conclusion IMRT seems able to reduce toxicity in selected patients treated with postoperative RT for BC. Further analyses are needed to better define patients who are candidates for this treatment modality. PMID:28293119

    Full Text Available The paper considers the current views of the prevalence, clinical picture, approaches to the diagnosis and treatment of one of the most commonneurological complications of diabetes mellitus – diabetic polyneuropathy, and both its somatic and autonomous manifestations. Neuropathy ismost common in diabetic patients and its clinical forms reflect the severe course of diabetes mellitus and serve as an unfavorable prognostic signthat is associated with an approximately 5-fold increase in mortality. At the same time, the timely detection and adequate correction of the manifestations of neuropathy may substantially improve quality of life in the patients. The possibilities of pathogenetic therapy for diabetic polyneuropathy associated mainly with the use of benfotiamine and alpha-lipoic acid, as well as symptomatic therapy for its individual manifestationsare considered.

    Uveitis, a group of conditions characterized by intraocular inflammation, is a major cause of sight loss in the working population. Most uveitis seen in Western countries is noninfectious and appears to be autoimmune or autoinflammatory in nature, requiring treatment with immunosuppressive and/or anti-inflammatory drugs. In this educational review, we outline the ideal characteristics of drugs for uveitis and review the data to support the use of current and emerging therapies in this context. It is crucial that we continue to develop new therapies for use in uveitis that aim to suppress disease activity, prevent accumulation of damage, and preserve visual function for patients with the minimum possible side effects.

  1. Management of salivary gland malignancies: current and developing therapies

    Full Text Available Salivary gland tumors are rare, clinically diverse neoplasms that represent less than 1% of all malignancies. In locoregional recurrent or metastatic disease, systemic therapy is the standard approach. While numerous small phase II studies have evaluated the activity of cytotoxic agents, either alone or in combination, the response rates are generally modest with objective response rates ranging from 15%–50%. Duration of response is cited in the range of 6–9 months. Given this, further evaluation of novel therapies is mandatory in these diseases. With the emergence of molecular targeted therapy, these tumors become optimal candidates for trials of investigational drugs and established drugs for new indications. Of note, given the often indolent nature of disease, only patients with progressive disease should be enrolled and treated on these clinical trials. Study designs must incorporate stringent inclusion criteria to enable accurate reporting of disease response and stabilization. With dedication and co-operation, patients with these rare neoplasms can be accrued to clinical trials and the establishment of new treatment guidelines will be forthcoming.

    Hadron therapy (including protons and ions) is still expanding worldwide, although still limited by the cost and thus the number of available facilities. If the historical indications remain eye melanomas, skull base tumours and paediatric tumours for protontherapy; and salivary glands, paranasal sinus and nasal cavity tumours, and soft tissue sarcomas for carbon ions, no conclusion can be drawn about the role of these modalities for other tumours, such as prostate, lung cancers. Since 2013, more than 100 clinical trials are on-going, including comparisons between advanced photons modalities, protontherapy and carbon ions therapy. An important technological and scientific (physics, radiobiology) effort has been made in parallel in order to reduce the cost of the facilities and to fully take advantages of the beam properties: standardization of beam scanning, image guided treatment, robust and 4D planning. Furthermore, the increasing number of facilities, the development of hypofractionation and the selection of indications will contribute to find the true place of particle therapy, despite the "screening effect" of the cost. The long term effects assessment on large patient cohorts will allow or not to correlate adverse effects and dosimetric data, always evoked.

    Prepubertal boys treated for cancer may exhibit impaired fertility in later life. A number of chemotherapeutic agents have been identified as being gonadotoxic, and certain treatment regimens, such as that used for Hodgkin's disease, are particularly associated with subsequent infertility. Radiotherapy may also cause gonadal damage, most notably following direct testicular irradiation or total body irradiation. Because of the varied nature of the cytotoxic insult, it can be difficult to predict the likelihood of infertility in later life. Currently it is not possible to detect gonadal damage early due to the lack of a sensitive marker of gonadal function in the prepubertal age group. Semen cryopreservation is currently the only method of preserving fertility in patients receiving gonadotoxic therapy. This is only applicable to postpubertal patients and can be problematic in the adolescent age group. At present there is no provision for the prepubertal boy, although there are a number of experimental methods currently being investigated. By harvesting testicular tissue prior to gonadotoxic therapy, restoration of fertility could be achieved following treatment, either by germ cell transplantation or by in vitro maturation of the germ cells harvested.Alternatively, rendering the testes quiescent during cytotoxic treatment may protect the germ cells from subsequent damage. In addition to the many scientific and technical issues to be overcome prior to clinical application of these techniques, a number of ethical and legal issues must also be addressed to ensure a safe and realistic prospect forfuture fertility in these patients.

    The objective of this study is to provide a new methodology for well abandonment. This practice is becoming more and more important because of the increasing number of production fields being abandoned. We strongly recommend a study of cement slurries properties for specific use in temporary and permanent abandonment plugs based on the estimation of the cement slurry hardened when placed in the well. By using specific additives, it is possible to achieve very stable slurries. For example, when permeability is reduced, formation fluid migration can be blocked and chemical reactions between the fluid and the slurry may be inhibited. With this objective, we present a laboratory investigation model and an example of slurry testing recommendation. During the abandonment operation, all records of the well characteristics should be maintained to include the reason for the abandonment, and location of fresh water, brine, and hydrocarbon zones that may exist. This documentation will also allow the analysis of solutions for the problems that originally caused the abandonment of the well. This data could be important for future use by environmental protection commissions to reopen or to drill an adjacent well. Given the high price of oil, it may now be economically feasible to reopen the well, if the reason for abandonment was low productivity. This way, a critical analysis of the current conditions of well and field abandonment in the country is presented. Based on this information, a review of the current standards is suggested. (author)

    Breast cancer is one of the most common malignancies among women, representing nearly 30% of newly diagnosed cancers every year. Till date, various therapeutic interventions, including surgery, chemotherapy, hormonal therapy, and radiotherapy are available and are known to cause a significant decline in the overall mortality rate. However, therapeutic resistance, recurrence and lack of treatment in metastasis are the major challenges that need to be addressed. Increasing evidence suggests the presence of cancer stem cells (CSCs) in heterogeneous population of breast tumors capable of selfrenewal and differentiation and is considered to be responsible for drug resistance and recurrence. Therefore, compound that can target both differentiated cancer cells, as well as CSCs, may provide a better treatment strategy. Due to safe nature of dietary agents and health products, investigators are introducing them into clinical trials in place of chemotherapeutic agents.This current review focuses on phytochemicals, mainly flavonoids that are in use for breast cancer therapy in preclinical phase. As phytochemicals have several advantages in breast cancer and cancer stem cells, new synthetic series for breast cancer therapy from analogues of most potent natural molecule can be developed via rational drug design approach.

    Brain tumors are the second most common malignancy and the major cause of cancer related mortality in children. Though significant advances in neuroimaging, neurosurgery, radiation therapy and chemotherapy have evolved over the years, overall survival rate remains less than 75%. Malignant gliomas, high risk medulloblastoma with recurrence and infant brain tumors continue to be a major cause of therapeutic frustration. Even today diffuse pontine gliomas are universally fatal. Though tumors like low grade glioma have an overall excellent survival, recurrences and progression in eloquent areas pose therapeutic challenges. As research continues to unravel the biology including key molecules and signaling pathways responsible for the oncogenesis of different childhood brain tumors, novel targeted therapies are profiled. Identification of major targets like the Epidermal Growth factor Receptor (EGFR), Platelet Derived Growth Factor Receptor (PDGFR), Vascular Endothelial Growth factor (VEGF) and key signaling pathways like the MAPK and PI3K/Akt/mTOR has enabled us over the recent years to better understand tumor behavior and design tailored therapy. These efforts have improved overall survival of children with brain tumors. This review article discusses the current status of common brain tumors in children and the newer therapeutic approaches.

    Gene therapy using autologous haematopoietic stem cells offers a valuable treatment option for patients with primary immunodeficiencies who do not have access to an HLA-matched donor, although such treatments have not been without their problems. This review details gene therapy trials for X-linked and adenosine deaminase (ADA)-deficient severe combined immunodeficiency (SCID), Wiskott-Aldrich syndrome (WAS) and chronic granulomatous disease (CGD). X-linked SCID was chosen for gene therapy because of previous 'natural' genetic correction through a reversion event in a single lymphoid precursor, demonstrating limited thymopoiesis and restricted T-lymphocyte receptor repertoire, showing selective advantage of progenitors possessing the wild-type gene. In early studies, patients were treated with long terminal repeats-intact gamma-retroviral vectors, without additional chemotherapy. Early results demonstrated gene-transduced cells, sustained thymopoiesis, and a diverse T-lymphocyte repertoire with normal function. Serious adverse effects were subsequently reported in 5 of 20 patients, with T-lymphocyte leukaemia developing, secondary to the viral vector integrating adjacent to a known oncogene. New trials using self-inactivating gamma-retroviral vectors are progressing. Trials for ADA-SCID using gamma-retroviral vectors have been successful, with no similar serious adverse effects reported; trials using lentiviral vectors are in progress. Patients with WAS and CGD treated with early gamma-retroviral vectors have developed similar lymphoproliferative adverse effects to those seen in X-SCID--current trials are using new-generation vectors. Targeted gene insertion using homologous recombination of corrected gene sequences by cellular DNA repair pathways following targeted DNA breakage will improve efficacy and safety of gene therapy. A number of new techniques are discussed.

  13. Applicability of RNA interference in cancer therapy: Current status

    2015-01-01

    Full Text Available Cancer is a manifestation of dysregulated gene function arising from a complex interplay of oncogenes and tumor suppressor genes present in our body. Cancer has been constantly chased using various therapies but all in vain as most of them are highly effective only in the early stages of cancer. Recently, RNA interference (RNAi therapy, a comparatively new entrant is evolving as a promising player in the battle against cancer due to its post-transcriptional gene silencing ability. The most alluring feature of this non-invasive technology lies in its utility in the cancer detection and the cancer treatment at any stage. Once this technology is fully exploited it can bring a whole new era of therapeutics capable of curing cancer at any stage mainly due to its ability to target the vital processes required for cell proliferation such as response to growth factors, nutrient uptake/synthesis, and energy generation. This therapy can also be used to treat stage IV cancer, the most difficult to treat till date, by virtue of its metastasis inhibiting capability. Recent research has also proved that cancer can even be prevented by proper modulation of physiological RNAi pathways and researchers have found that many nutrients, which are a part of routine diet, can effectively modulate these pathways and prevent cancer. Even after having all these advantages the potential of RNAi therapy could not be fully tapped earlier, due to many limitations associated with the administration of RNAi based therapeutics. However, recent advancements in this direction, such as the development of small interfering RNA (siRNA tolerant to nucleases and the development of non-viral vectors such as cationic liposomes and nanoparticles, can overcome this obstacle and facilitate the clinical use of RNAi based therapeutics in the treatment of cancer. The present review focuses on the current status of RNAi therapeutics and explores their potential as future diagnostics and

    Full Text Available Blake Wynia,1 Jed C Kaminetsky21Department of Urology, New York University Langone Medical Center, 2University Urology Associates, Manhattan Medical Research, New York, NY, USAAbstract: Exogenous testosterone was introduced nearly 80 years ago as a pharmaceutical agent to treat male hypogonadism. Researchers continue to enhance the pharmacokinetic profile of testosterone to improve various benefits, including mood and sexual function, among other potential benefits. The modalities that are currently available include implants, intramuscular injections, oral formulations, transdermal delivery systems (ie, patches, gels, and a solution, transbuccal delivery systems, and most recently, intranasal testosterone. Each of these products differs by the delivery system, half-life, and ability to mimic physiological levels of testosterone. While we recognize the unique characteristics and benefits of existing agents, we must address unmet needs, including how best to mimic physiological levels of testosterone and how to administer it through a more effective, safe, and convenient mechanism. In our overview of current and emerging testosterone therapies, we will examine these topics and address the controversy of prostate cancer and cardiovascular risk.Keywords: hypogonadism, low testosterone, testosterone replacement therapy, cardiovascular

    The current standard of care for glioblastoma (GBM) is maximal surgical resection with adjuvant radiotherapy and temozolomide (TMZ). As the 5-year survival with GBM remains at a dismal <10%, novel therapies are needed. Immunotherapies such as the dendritic cell (DC) vaccine, heat shock protein vaccines, and epidermal growth factor receptor (EGFRvIII) vaccines have shown encouraging results in clinical trials, and have demonstrated synergistic effects with conventional therapeutics resulting in ongoing phase III trials. Chemoradiation has been shown to have synergistic effects when used in combination with immunotherapy. Cytotoxic ionizing radiation is known to trigger pro-inflammatory signaling cascades and immune activation secondary to cell death, which can then be exploited by immunotherapies. The future of GBM therapeutics will involve finding the place for immunotherapy in the current treatment regimen with a focus on developing strategies. Here, we review current GBM therapy and the evidence for combination of immune checkpoint inhibitors, DC and peptide vaccines with the current standard of care.

    Rhabdomyosarcoma (RMS) represents a rare, heterogeneous group of mesodermal malignancies with skeletal muscle differentiation. One major subgroup of RMS tumors (so-called “fusion-positive” tumors) carries exclusive chromosomal translocations that join the DNA-binding domain of the PAX3 or PAX7 gene to the transactivation domain of the FOXO1 (previously known as FKHR) gene. Fusion-negative RMS represents a heterogeneous spectrum of tumors with frequent RAS pathway activation. Overtly metastatic disease at diagnosis is more frequently found in individuals with fusion-positive than in those with fusion-negative tumors. RMS is the most common pediatric soft-tissue sarcoma, and approximately 60% of all children and adolescents diagnosed with RMS are cured by currently available multimodal therapies. However, a curative outcome is achieved in <30% of high-risk individuals with RMS, including all those diagnosed as adults, those diagnosed with fusion-positive tumors during childhood (including metastatic and nonmetastatic tumors), and those diagnosed with metastatic disease during childhood (including fusion-positive and fusion-negative tumors). This white paper outlines current challenges in RMS research and their implications for developing more effective therapies. Urgent clinical problems include local control, systemic disease, need for improved risk stratification, and characterization of differences in disease course in children and adults. Biological challenges include definition of the cellular functions of PAX-FOXO1 fusion proteins, clarification of disease heterogeneity, elucidation of the cellular origins of RMS, delineation of the tumor microenvironment, and identification of means for rational selection and testing of new combination therapies. To streamline future therapeutic developments, it will be critical to improve access to fresh tumor tissue for research purposes, consider alternative trial designs to optimize early clinical testing of candidate

    Ulcerative colitis (UC) and Crohn's disease (CD) constitute the two major groups of idiopathic disorders in inflammatory bowel disease (IBD). Environmental factors, genetic factors and immune responses have been considered as the major etiology of IBD. Despite the diversified pathogenesis of the disease, no guaranteed curative therapeutic regimen has been developed so far. This review summarizes the knowledge on the pathophysiology and current treatment approaches of IBD. Since IBD is caused by excessive and tissue- disruptive inflammatory reactions of the gut wall, down-regulation of the immune responses may allow the damaged mucosa to heal and reset the physiological functions of the gut back to normal. Current pharmacotherapy through modulation of neutrophil-derived factors, cytokines, adhesion molecules and reactive oxygen/nitrogen metabolites has been utterly described. Categories of treatment modalities include corticosteroids, aminosalicylates, immunomodulators, antibiotics, probiotics, and a series of unique novel agents. The use of anti-tumor necrosis factor monoclonal antibody (Infliximab), recombinant anti-inflammatory cytokines and related gene therapy has been covered. In addition, discussions on dietary supplementation and heparin treatment are also included. The anti-inflammatory and immunoregulatory potential of investigational agents such as nicotine and the filtered protective compounds from tobacco smoke, as well as active herbal medicinal compounds were tested in our previous experimental works, whereas promising findings have been presented here. With the discovery of novel target-oriented agents, more effective and relatively harmless approaches of IBD therapy could be established to achieve a curative outcome. Indeed, more experimental and clinical studies are needed to confirm the relevance of these therapies.

    Dyslipidemia has significantly contributed to the increase of death and morbidity rates related to cardiovascular diseases. Clinical nutrition service provided by dietitians has been reported to have a positive effect on relief of medical symptoms or reducing the further medical costs. However, there is a lack of researches to identify key competencies and job standard for clinical dietitians to care patients with dyslipidemia. Therefore, the purpose of this study was to analyze the job components of clinical dietitian and develop the standard for professional practice to provide effective nutrition management for dyslipidemia patients. The current status of clinical nutrition therapy for dyslipidemia patients in hospitals with 300 or more beds was studied. After duty tasks and task elements of nutrition care process for dyslipidemia clinical dietitians were developed by developing a curriculum (DACUM) analysis method. The developed job standards were pretested in order to evaluate job performance, difficulty, and job standards. As a result, the job standard included four jobs, 18 tasks, and 53 task elements, and specific job description includes 73 basic services and 26 recommended services. When clinical dietitians managing dyslipidemia patients performed their practice according to this job standard for 30 patients the job performance rate was 68.3%. Therefore, the job standards of clinical dietitians for clinical nutrition service for dyslipidemia patients proposed in this study can be effectively used by hospitals.

    Full Text Available Sexual dysfunction and more specifically erectile dysfunction (ED can be a harbinger of serious occult medical conditions. ED can be considered a clinical manifestation of generalized vascular disease and therefore shares similar risk factors: aging, hypertension, diabetes mellitus, hypercholesterolemia and smoking. The initial evaluation of men with ED should be thorough. Studies of normal and abnormal penile tumescence have led to the discovery of many important pathways. The greatest medical advance in the management of male sexual dysfunction since the identification of androgens have been the discoveries that nitric oxide (NO is the primary neuro-modulator of penile smooth muscle relaxation and that oral phosphodiesterase type 5 inhibitors enhance erection quality through the NO mechanism. As a consequence of oral pharmacotherapies, the role of invasive diagnostics has diminished. Most guidelines recommend only history, physical exam and limited laboratory testing prior to instituting oral therapies for ED. In 2006 we still have unanswered questions about ED and these will frame the role of future diagnosis and therapy: can lifestyle changes alone improve erectile function; is ED a marker for the development of atherosclerotic heart disease, do lower urinary tract symptoms of benign prostatic hypertrophy and ED share a common pathway?

    A need exists in the parachute industry for a standard method of defining and guiding the formation of textile drawings. Textile drawings have their own unique problems associated with their development. Unlike mechanical parts, textiles have no mass in cross section. Therefore, a cross-sectioned view has no hash marks. Hidden views are not usually incorporated in textile drawings as they are easily confused with stitch formations. Side views of textile parts are depicted using only one line to show thickness. This report will address these and other unique drawing problems associated with the development of parachute drawings and will offer, as a base, standards to be used when developing these drawings. 21 figs.

This article presents the results of a survey related to SWD, showing data about the equipment, conditions of use, visual inspection and analysis of accompanying documents, having as reference the requirements of the Brazilian standards NBR IEC 601-1 and NBR IEC 601-2-3. Electrical safety tests were also carried out for the equipment and the installation. The results showed that manufacturers do not completely follow the standards and there is a lack of knowledge of these standards by the physiotherapists. Electrical safety tests presented measured values of equipment leakage current within the limits of the standards, but installation presented fails. One can conclude that it is necessary a greater awareness by manufacturers and professionals regarding the standards including electrical safety in order to assure the correct use of SWD equipment.Equipamentos de diatermia por ondas curtas (DOC são utilizados em clínicas de fisioterapia e aplicados terapeuticamente, utilizando radiação de radiofreqüência (RF em 27,12 MHz.

Its prevalence is certain to increase substantially as the population ages. Treatments currently available for the disease include laser photocoagulation, verteporfin photodynamic therapy, and intravitreal injections of corticosteroids and anti-angiogenic agents. Many studies have reported the benefits of each of these treatments, although none is without its risks. No intervention actually cures AMD, nor the neovascularization associated with it. However, its symptoms are treated with varying degrees of success. Some treatments stabilize or arrest the progress of the disease. Others have been shown to reverse some of the damage that has already been done. These treatments can even lead to visual improvement. This paper will review the major classes of drugs and therapies designed to treat this condition.Keywords: wet AMD, neovascularization, PDT, steroids, anti-angiogenesis

    Beta-thalassemia is a group of frequent genetic disorders resulting in the synthesis of little or no β-globin chains. Novel approaches are being developed to correct the resulting α/β-globin chain imbalance, in an effort to move beyond the palliative management of this disease and the complications of its treatment (e.g. life-long red blood cell transfusion, iron chelation, splenectomy), which impose high costs on healthcare systems. Three approaches are envisaged: fetal globin gene reactivation by pharmacological compounds injected into patients throughout their lives, allogeneic hematopoietic stem cell transplantation (HSCT), and gene therapy. HSCT is currently the only treatment shown to provide an effective, definitive cure for β-thalassemia. However, this procedure remains risky and histocompatible donors are identified for only a small fraction of patients. New pharmacological compounds are being tested, but none has yet made it into common clinical practice for the treatment of beta-thalassemia major. Gene therapy is in the experimental phase. It is emerging as a powerful approach without the immunological complications of HSCT, but with other possible drawbacks. Rapid progress is being made in this field, and long-term efficacy and safety studies are underway. Copyright © 2016 Chang Gung University. Published by Elsevier B.V. All rights reserved.

    Full Text Available One century after its discovery, Chagas disease, caused by the protozoan, Trypanosoma cruzi, remains a major health problem in Latin America. Mortality and morbidity are mainly due to chronic processes that lead to dysfunction of the cardiac and digestive systems. About one third of the chronic chagasic individuals have or will develop the symptomatic forms of the disease, with cardiomyopathy being the most common chronic form. This is a progressively debilitating disease for which there are no currently available effective treatments other than heart transplantation. Like in other cardiac diseases, tissue engineering and cell therapy have been investigated in the past few years as a means of recovering the heart function lost as a consequence of chronic damage caused by the immune-mediated pathogenic mechanisms elicited in individuals with chronic chagasic cardiomyopathy. Here we review the studies of cell therapy in animal models and patients with chronic Chagas disease and the perspectives of the recovery of the heart function lost due to infection with T. cruzi.

    2017-01-01

    Full Text Available Hidradenitis suppurativa (HS is a chronic, recurrent, inflammatory disease of apocrine gland-bearing skin which affects approximately 1–4% of the population. The disease is more common in women and patients of African American descent and approximately one-third of patients report a family history. Obesity and smoking are known risk factors, but associations with other immune disorders, especially inflammatory bowel disease, are also recognized. The pathogenesis of HS is poorly understood and host innate or adaptive immune response, defective keratinocyte function, and the microbial environment in the hair follicle and apocrine gland have all been postulated to play a role in disease activity. While surgical interventions can be helpful to reduce disease burden, there is a high recurrence rate. Increasingly, data supports targeted immune therapy for HS, and longitudinal studies suggest benefit from these agents, both when used alone and as an adjunct to surgical treatments. The purpose of this review is to outline the current data supporting use of targeted immune therapy in HS management.

    Full Text Available Attention deficit hyperactivity disorder is a developmental disorder with an age onset prior to 7 years. Children with ADHD have significantly lower ability to focus and sustain attention and also score higher on impulsivity and hyperactivity. Stimulants, such as methylphenidate, have remained the mainstay of ADHD treatment for decades with evidence supporting their use. However, recent years have seen emergence of newer drugs and drug delivery systems, like osmotic release oral systems and transdermal patches, to mention a few. The use of nonstimulant drugs like atomoxetine and various other drugs, such as a-agonists, and a few antidepressants, being used in an off-label manner, have added to the pharmacotherapy of ADHD. This review discusses current trends in drug therapy of ADHD and highlights the promise pharmacogenomics may hold in the future.

    Full Text Available Toxicity resulting from prescription drugs such as tricyclic antidepressants and cardioactive steroids, as well as drugs of abuse and exposure to environmental chemicals, represents a major need for detoxification treatments. Particles and colloids, antibody fragments (Fab, and indirect treatment methods such as macroemulsions, are currently being developed or employed as detoxification therapies. Colloids, particles, and protein fragments typically mitigate toxicity by binding to the toxin and reducing its concentration in vital organs. Indirect methods such as macroemulsions and sodium bicarbonate act directly on the affected organs, rather than the toxin. In this review, key design parameters (i.e. binding affinity, biocompatibility, pharmacokinetics are discussed for each type of detoxification treatment. In addition, some of the latest research in each area is reviewed.

    2017-01-01

    Full Text Available Lectins are carbohydrate recognizing proteins originating from diverse origins in nature, including animals, plants, viruses, bacteria and fungus. Due to their exceptional glycan recognition property, they have found many applications in analytical chemistry, biotechnology and surface chemistry. This manuscript explores the current use of lectins for cancer diagnosis and therapy. Moreover, novel drug delivery strategies aiming at improving lectin’s stability, reducing their undesired toxicity and controlling their non-specific binding interactions are discussed. We also explore the nanotechnology application of lectins for cancer targeting and imaging. Although many investigations are being conducted in the field of lectinology, there is still a limited clinical translation of the major findings reported due to lectins stability and toxicity concerns. Therefore, new investigations of safe and effective drug delivery system strategies for lectins are warranted in order to take full advantage of these proteins.

    2014-01-01

    In photodynamic therapy (PDT) a photosensitizer – a molecule that is activated by light – is administered and exposed to a light source. This leads both to destruction of cells targeted by the particular type of photosensitizer, and immunomodulation. Given the ease with which photosensitizers and light can be delivered to the skin, it should come as no surprise that PDT is an increasingly utilized therapeutic in dermatology. PDT is used commonly to treat precancerous cells, sun-damaged skin, and acne. It has reportedly also been used to treat other conditions including inflammatory disorders and cutaneous infections. This review discusses the principles behind how PDT is used in dermatology, as well as evidence for current applications of PDT. PMID:24899818

    Pancreatic cancer is one of the most lethal solid tumors. The prognosis of metastatic pancreatic adenocarcinoma remains dismal, with a median survival of less than 1 year, due in large part to the fact that pancreatic adenocarcinoma is notoriously refractory to chemotherapy. However, there recently have been significant improvements in outcomes for patients with pancreatic adenocarcinoma: ongoing trials have shown promise, and these may lead to still further progress. Here we review the current treatment paradigms for metastatic disease, focusing on ways to ameliorate symptoms and lengthen survival. We then summarize recent advances in our understanding of the molecular and cellular aspects of pancreatic cancer. Finally, we outline new approaches currently under development for the treatment of metastatic disease, arising from our improved understanding of the genetic and nongenetic alterations within pancreatic cancer cells-and of interactions between cancer cells, the tumor microenvironment, and the immune system.

    During the past three decades, improvements in the treatment of childhood leukemia have resulted in high cure rates, particularly for acute lymphoblastic leukemia (ALL). Unfortunately, successful therapy has come with a price, as significant morbidity can result from neurological affects which harm the brain and spinal cord. The expectation and hope is that chemotherapy, as a primary means of CNS therapy, will result in acceptable disease control with less CNS morbidity than has been observed with combinations of chemotherapy and radiotherapy over the past several decades. In this review we discuss the poignant, historical aspects of CNS leukemia therapy, outline current methods of systemic and CNS leukemia therapy, and present imaging findings we have encountered in childhood leukemia patients with a variety of acute neurological conditions. A major objective of our research is to understand the neuroimaging correlates of acute and chronic effects of cancer and therapy. Specific features related to CNS leukemia and associated short-term toxicities, both disease- and therapy-related, are emphasized in this review with the specific neuroimaging findings. Specific CNS findings are similarly important when treating acute myelogenous leukemia (AML), and details of leukemic involvement and toxicities are also presented in this entity. Despite contemporary treatment approaches which favor the use of chemotherapy (including intrathecal therapy) over radiotherapy in the treatment of CNS leukemia, children still occasionally experience morbid neurotoxicity. Standard neuroimaging is sufficient to identify a variety of neurotoxic sequelae in children, and often suggest specific etiologies. Specific neuroimaging findings frequently indicate a need to alter antileukemia therapy. It is important to appreciate that intrathecal and high doses of systemic chemotherapy are not innocuous and are associated with acute, specific, recognizable, and often serious neurological

    Full Text Available Hepatitis C virus (HCV represents a major health burden, with an estimated 180 million chronically infected individuals worldwide. These patients are at increased risk of developing liver cirrhosis and hepatocellular carcinoma. Infection with HCV is the leading cause of liver transplantation in the Western world. Currently, the standard of care (SoC consists of pegylated interferon alpha (pegIFN-α and ribavirin (RBV. However this therapy has a limited efficacy and is associated with serious side effects. Therefore more tolerable, highly potent inhibitors of HCV replication are urgently needed. Both Specifically Targeted Antiviral Therapy for HCV (STAT-C and inhibitors that are believed to interfere with the host-viral interaction are discussed.

The initial cause of this deplorable statistics is the absence of a clear concept of the pathogenesis of OC and hence the justified prevention and methodology of early diagnosis of the disease; in this connection, therapy that proves to be ineffective is frequently used by medical oncologists in their daily practice. As a consequence, there is a high proportion of its further progression: the rates of early and late recurrences were about 30 and 60–65 %, respectively; most of which are drug resistant to further chemotherapy cycles. By taking into account these strikingly modest statistics, it becomes apparent that oncologists desire to make changes in the existing treatment regimen to achieve meaningful results. To use target drugs is one of these promising areas owing to new views on the concept of the pathogenesis of OC.Nevertheless, considering a wide variety of the signaling cascades and molecules, which are involved in the process of carcinogenesis, even target compounds, if they have only one point of application, cannot always produce their desirable therapeutic effect and their co-administration is responsible for high toxicity. In this light, the most effective drugs are indole-3-carbinol and epigallocathechin-3-gallate, which virtually cause no adverse reactions and can block various molecular targets at different levels of the mechanism of malignant transformation. Based on L. A. Ashrafyan, s concept of two pathogenetic variants of sporadic OC (2009 and on the recent findings in molecular biology and epigenetics, the incorporation of the above medications into the standard treatment regimen for OC should increase survival rates and change the nature of recurrence by that of more locally advanced forms. On this basis, a clinical trial was carried out to study

    Prostate cancer and treatment with androgen deprivation therapy (ADT) affect significant numbers of the male population. Endocrine effects of ADT are a critical consideration in balancing the benefits and risks of treatment on long-term survival and quality of life. This review highlights the latest advances in androgen manipulation in prostate cancer with an emphasis on the effects of ADT on muscle and bone, which universally affects the health and well-being of men undergoing ADT for prostate cancer. Muscle mass declines with ADT; however, the evidence that this correlates with a decrease in muscle strength or a decrease in physical performance is discordant. Cortical bone decay also occurs in association with an increase in fracture risk, hence optimization of musculoskeletal health in men undergoing ADT is crucial. The role of exercise, and current and emerging anabolic therapies for muscle as well as various new strategies to prevent loss of bone mass in men undergoing ADT are discussed. Future well-designed, prospective, controlled studies are required to elucidate the effects of ADT on physical performance, which are currently lacking, and larger randomized controlled trials are required to test the efficacy of medical therapies and exercise interventions to target proven deficits and to ensure safety in men with prostate cancer.

    Full Text Available Dan J FintelBluhm Cardiovascular Institute, Feinberg School of Medicine, Northwestern University, Chicago, IL, USAAbstract: Clinical presentations of atherothrombotic vascular disease, such as acute coronary syndromes, ischemic stroke or transient ischemic attack, and symptomatic peripheral arterial disease, are major causes of morbidity and mortality worldwide. Platelet activation and aggregation play a seminal role in the arterial thrombus formation that precipitates acute manifestations of atherothrombotic disease. As a result, antiplatelet therapy has become the cornerstone of therapy for the prevention and treatment of atherothrombotic disease. Dual antiplatelet therapy with aspirin and a P2Y12 adenosine diphosphate (ADP receptor inhibitor, such as clopidogrel or prasugrel, is the current standard-of-care antiplatelet therapy in patients with acute coronary syndromes managed with an early invasive strategy. However, these agents are associated with several important clinical limitations, including significant residual risk for ischemic events, bleeding risk, and variability in the degree of platelet inhibition. The residual risk can be attributed to the fact that aspirin and P2Y12 inhibitors block only the thromboxane A2 and ADP platelet activation pathways but do not affect the other pathways that lead to thrombosis, such as the protease-activated receptor-1 pathway stimulated by thrombin, the most potent platelet agonist. Bleeding risk associated with aspirin and P2Y12 inhibitors can be explained by their inhibitory effects on the thromboxane A2 and ADP pathways, which are critical for protective hemostasis. Interpatient variability in the degree of platelet inhibition in response to antiplatelet therapy may have a genetic component and contribute to poor clinical outcomes. These considerations underscore the clinical need for therapies with a novel mechanism of action that may reduce ischemic events without increasing the bleeding risk

    This study examines the characteristics of the electric field induced in the brain by electroconvulsive therapy (ECT) with individualized current amplitude. The electric field induced by bilateral (BL), bifrontal (BF), right unilateral (RUL), and frontomedial (FM) ECT electrode configurations was computed in anatomically realistic finite element models of four nonhuman primates (NHPs). We generated maps of the electric field strength relative to an empirical neural activation threshold, and determined the stimulation strength and focality at fixed current amplitude and at individualized current amplitudes corresponding to seizure threshold (ST) measured in the anesthetized NHPs. The results show less variation in brain volume stimulated above threshold with individualized current amplitudes (16-36%) compared to fixed current amplitude (30-62%). Further, the stimulated brain volume at amplitude-titrated ST is substantially lower than that for ECT with conventional fixed current amplitudes. Thus individualizing the ECT stimulus current could compensate for individual anatomical variability and result in more focal and uniform electric field exposure across different subjects compared to the standard clinical practice of using high, fixed current for all patients.

    Full Text Available Background. Today there are 3 trends in favor of intraperitoneal (IP chemotherapy: maintenance of its potential 5- and 10-year survival benefit in patients with ovarian cancer (OC; advantages of the IP administration of drugs even after nonoptimal surgery; enhancement of the efficiency of chemotherapy irrespective of the number of IP treatment cycles. There is also an expanded list of possible IP medicines and incorporation of novel targeted drugs into treatment regimens. However, the long-expected data of the most recent randomized trial GOG 0252 have proven deplorable and led to the activation of discussions on the role of IP therapy.Objective: to generalize the experience of 4 oncology departments with IP therapy in patients with disseminated OC and to compare the findings with those obtained by the world’s leading medical centers.Materials and methods. The retrospective analysis included 76 patients with Stage IIIC OC who had received IP chemotherapy in accordance with 3 regimens. For standardization of IP treatment procedures, the investigators assessed the following indicators: age; tumor morphological type; surgical radicality; catheter model and port placement procedure; drug administration route; number of treatment cycles; efficiency of therapy from expert ultrasonographic findings and CA-124, HE4, CA-19.9 marker levels, time to disease progression. The analysis also involved adverse manifestations, methods of their correction and the reasons for early treatment discontinuation were separately reported. The obtained data were processed using standard statistical programs.Results. 55 of the 76 patients could complete more than 4 IP therapy cycles. Among them, only 4 patients were observed to have disease progression at follow-ups lasting over 24 months.Conclusion. Current IP therapy is a safe and convenient drug treatment in patients with OC after optimal cytoreductive surgery. The mastery and standardization of the

    Cancers of esophagus and stomach are common malignant diseases worldwide, and they are associated with serious morbidity and high mortality rates. When diagnosed at an early stage, gastro-esophageal cancers are potentially curable. Neo-adjuvant or adjuvant therapies using both chemotherapy and radiation therapy have been shown to reduce the risk of local recurrence and distant metastasis. For advanced or metastatic tumors, systemic chemotherapy offers symptomatic palliation and moderate benefits in survival. With recent advances in anti-cancer therapeutics, progress has been made to improve treatment response and life expectancy in patients with advanced gastro-esophageal cancers. Furthermore, the clinical use of molecularly targeted agents in combination with cytotoxic chemotherapeutics is being evaluated in a number of ongoing clinical trials. In this article, we review currently used standard systemic therapies including recently evolving targeted therapies for metastatic gastro-esophageal cancers, as well as the proven role and the regimens that are used as neoadjuvant and adjuvant treatment in localized gastro-esophageal cancers.

    Modern advances in genomics and cancer biology have produced an unprecedented body of knowledge regarding the molecular pathogenesis of lymphoma. The diverse histological subtypes of lymphoma are molecularly heterogeneous, and most likely arise from distinct oncogenic mechanisms. In parallel to these advances in lymphoma biology, several new classes of molecularly targeted agents have been developed with varying degrees of efficacy across the different types of lymphoma. In general, the development of new drugs for treating lymphoma has been mostly empiric, with a limited knowledge of the molecular target, its involvement in the disease, and the effect of the drug on the target. Thus, the variability observed in clinical responses likely results from underlying molecular heterogeneity. In the era of personalized medicine, the challenge for the treatment of patients with lymphoma will involve correctly matching a molecularly targeted therapy to the unique genetic and molecular composition of each individual lymphoma. In this Review, we discuss current and emerging biomarkers that can guide treatment decisions for patients with lymphoma, and explore the potential challenges and strategies for making biomarker-driven personalized medicine a reality in the cure and management of this disease.

    Morquio A syndrome is an autosomal recessive disorder, one of 50 lysosomal storage diseases (LSDs), and is caused by the deficiency of N-acetylgalactosamine-6-sulfate sulfatase (GALNS). Deficiency of this enzyme causes specific glycosaminoglycan (GAG) accumulation: keratan sulfate (KS) and chondroitin-6-sulfate (C6S). The majority of KS is produced in the cartilage, therefore, the undegraded substrates accumulate mainly in cartilage and in its extracelluar matrix (ECM), causing direct leads to direct impact on cartilage and bone development and leading to the resultant systemic skeletal spondyloepiphyseal dysplasia. Chondrogenesis ,the earliest phase of skeletal formation that leads to cartilage and bone formation is controlled by cellular interactions with the ECM, growth and differentiation factors and other molecules that affect signaling pathways and transcription factors in a temporal-spatial manner. In Morquio A patients, in early childhood or even at birth, the cartilage is disrupted presumably as a result of abnormal chondrogenesis and/ or endochondral ossification. The unique clinical features are characterized by a marked short stature, odontoid hypoplasia, protrusion of the chest, kyphoscoliosis, platyspondyly, coxa valga, abnormal gait, and laxity of joints. In spite of many descriptions of the unique clinical manifestations, diagnosis delay still occurs. The pathogenesis of systemic skeletal dysplasia in Morquio A syndrome remains an enigmatic challenge. In this review article, screening, diagnosis, pathogenesis and current and future therapies of Morquio A are discussed.

    Inflammatory bowel diseases(IBD), including Crohn’s disease(CD) and ulcerative colitis, are chronic relapsing and remitting diseases of the bowel, with an unknown etiology and appear to involve interaction between genetic susceptibility, environmental factors and the immune system. Although our knowledge and understanding of the pathogenesis and causes of IBD have improved significantly, the incidence in the pediatric population is still rising. In the last decade more drugs and treatment option have become available including 5-aminosalicylate,antibiotics, corticosteroids, immunomodulators and biological agents. Before the use of anti-tumor necrosis factor(TNF)-α became available to patients with IBD, the risk for surgery within five years of diagnosis was very high, however, with anti-TNF-α treatment the risk of surgery has decreased significantly. In the pediatric population a remission in disease can be achieved by exclusive enteral nutrition. Exclusive enteral nutrition also has an important role in the improvement of nutritional status and maintained growth. In this review we summarize the current therapeutic treatments in CD. The progress in the treatment options and the development of new drugs has led to optimized tactics for achieving the primary clinical goals of therapy- induction and maintenance of remission while improving the patient’s growth and overall well-being.

    Adrenal insufficiency (AI) is a rare endocrine disease, associated to increased mortality if left untreated. It can be due to a primary failure of the adrenal glands (primary AI) or malfunctioning of the hypothalamic-pituitary-adrenal axis (HPA) (secondary AI). The lack of data on incidence/prevalence of adrenal insufficiency in Spain complicates any evaluation of the magnitude of the problem in our country. Initial symptoms are non-specific, so often there is a delay in diagnosis. Current therapy with available glucocorticoids is associated with decreased quality of life in patients with treated AI, as well as with increased mortality and morbidity, probably related to both over-treatment and lack of hydrocortisone, associated with non-physiological peaks and troughs of the drug over the 24 hours. The availability of a new drug with a modified dual release (immediate and retarded), that requires one only daily dose, improves and simplifies the treatment, increases compliance as well as quality of life, morbidity and possibly mortality. This revision deals with the knowledge on the situation both globally and in Spain, prior to the availability of this new drug.

    Case report forms (CRFs) are used for structured-data collection in clinical research studies. Existing CRF-related standards encompass structural features of forms and data items, content standards, and specifications for using terminologies. This paper reviews existing standards and discusses their current limitations. Because clinical research is highly protocol-specific, forms-development processes are more easily standardized than is CRF content. Tools that support retrieval and reuse of existing items will enable standards adoption in clinical research applications. Such tools will depend upon formal relationships between items and terminological standards. Future standards adoption will depend upon standardized approaches for bridging generic structural standards and domain-specific content standards. Clinical research informatics can help define tools requirements in terms of workflow support for research activities, reconcile the perspectives of varied clinical research stakeholders, and coordinate standards efforts toward interoperability across healthcare and research data collection.

    5-fluorouracil(5-FU)therapy has advanced greatly over the past 50 years, achieving enhanced therapeutic effects and reduced adverse effects. By taking advantage of the metabolism of 5-FU, researchers have made efforts to develop prodrugs, combination drug products, and combination therapy regimens via biochemical modulation(BCM)with alteration of the drug metabolism. Examples include the advent of the prodrug tegafur(FT), followed by tegafur-uracil(UFT)and tegafurgimeracil- potassium oxonate(S-1)as combined products based on BCM. In the current standard treatment for gastrointestinal cancers, anticancer 5-FU derivatives serve as a platform for combination regimens with other cytotoxic agents or molecular- targeted drugs. To provide further improvements in anticancer therapy outcomes, novel molecular-targeted agents, immune checkpoint inhibitors, and other drugs are being developed, but 5-FU remains an attractive target that shows further potential for increased efficacy. In the future, the evolution of anticancer therapy with 5-FU derivatives is expected to continue via a variety of approaches.

    Multiple myeloma (MM) is a heterogeneous disease, and a variety of risk factors at the time of initial diagnosis can be used to stratify patients. In the first part of this 2-part series, we reviewed the currently identified prognostic factors, characterized by disease burden, host factors, tumor biology, and depth of response to therapy. However, these risk factors cannot be interpreted independently of therapies. Novel therapies have the potential to worsen or improve outcomes compared with conventional therapy in high-risk patients, or actually overcome the high-risk status, thereby resulting in reclassification as standard risk. For example, thalidomide (Thalomid, Celgene) is associated with worse outcomes in patients with high-risk cytogenetic abnormalities, such as deletion of chromosomes 13 and 17p, whereas proteasome inhibitors appear to overcome t(4;14). The second part of this series reviews the significance of various genetic risks in the era of novel therapies for MM.

    Music therapy is a service that has become more prevalent as an adjunct to medical practice-as its evidence base expands and music therapists begin to join the cardiology team in every phase of care, from the most serious cases to those maintaining good heart health. Although applications of music medicine, primarily listening to short segments of music, are capable of stabilizing vital signs and managing symptoms in the short-term, music therapy interventions by a qualified practitioner are showing promise in establishing deeper and more lasting impact. On the basis of mind-body approaches, stress/coping models, the neuromatrix theory of pain, and entrainment, music therapy capitalizes on the ability of music to affect the autonomic nervous system. Although only a limited number of randomized controlled trials pinpoint the efficacy of specific music therapy interventions, qualitative research reveals some profound outcomes in certain individuals. A depth of understanding related to the experience of living with a cardiovascular disease can be gained through music therapy approaches such as nonverbal music psychotherapy and guided imagery and music. The multifaceted nature of musical responsiveness contributes to strong individual variability and must be taken into account in the development of research protocols for future music therapy and music medicine interventions. The extant research provides a foundation for exploring the many potential psychosocial, physiological, and spiritual outcomes of a music therapy service for cardiology patients.

    Full Text Available In recent years remarkable progress has been made towards the understanding of proposed hallmarks of cancer development and treatment. However with its increasing incidence, the clinical management of cancer continues to be a challenge for the 21st century. Treatment modalities comprise of radiation therapy, surgery, chemotherapy, immunotherapy and hormonal therapy. Radiation therapy remains an important component of cancer treatment with approximately 50% of all cancer patients receiving radiation therapy during their course of illness; it contributes towards 40% of curative treatment for cancer. The main goal of radiation therapy is to deprive cancer cells of their multiplication (cell division potential. Celebrating a century of advances since Marie Curie won her second Nobel Prize for her research into radium, 2011 has been designated the Year of Radiation therapy in the UK. Over the last 100 years, ongoing advances in the techniques of radiation treatment and progress made in understanding the biology of cancer cell responses to radiation will endeavor to increase the survival and reduce treatment side effects for cancer patients. In this review, principles, application and advances in radiation therapy with their biological end points are discussed.

However, there are certain subgroups where combination therapy may be beneficial, e.g. sepsis due to carbapenem-resistant Enterobacteriaceae (CRE, bacteremic pneumococcal pneumonia, and patients with multiple organ failure. Well-designed prospective studies are needed to clearly define the role of combination therapy in these subgroups.

    Postural instability is a common impairment in idiopathic Parkinson's disease (PD). People with PD are prone to balance and walking difficulties. This study analyzed the feasibility of a prospective investigation of Computerized Dynamic Posturography (CDP) and standard Physical Therapy (PT) treatments in individuals with mild-moderate PD. Treatment took place at two sites: 1) CDP therapy at the Southeast Parkinson's Disease Research Education and Clinical Center (PADRECC) within a Veterans Affairs Medical Center and 2) standard physical therapy at a community outpatient rehabilitation center. Final analysis compared 15 patients randomly assigned for therapy to either the CDP or PT treatments. Therapy time was eight weeks (four weeks of CPD or PT followed by home therapy for four weeks). The CDP therapy included gradually intensified closed chain and mobility training. Standard PT consisted of upright, mat, and theraball exercises and gait training. The home exercise phase was identical for both groups. The pilot data demonstrated treatment was tolerated by 68 percent of the sample despite the occurrence of a progressive neurological condition and medical comorbidities. While results failed to reveal any differences between treatment groups, both groups demonstrated improvement on selected outcome measures. An expanded prospective study with methodological improvements appears warranted.

    Rosacea is a common chronic inflammatory disease, especially in patients with fair skin and positive family history. Typical locations are forehead, nose, cheeks and chin; the periorbital region is usually not involved. Clinical features can be very heterogeneous. Besides different subtypes (erythematotelangiectatic rosacea, papulopustular rosacea, phymatous rosacea), which often overlap, various special forms of rosacea exist. Up to 60% of patients with cutaneous rosacea suffer from ocular rosacea. In Germany, brimonidine, metronidazol, azelaic acid, and ivermectin are approved for topical therapy of rosacea; for systemic therapy, doxycycline at a subantimicrobial dose (40 mg/day) is the only approved substance. In case of resistance to this therapy, contraindications or side effects, various alternative therapies are available, however off-label.

    Insufficient pain education is problematic across the health care spectrum. Recent educational advancements have been made to combat the deficits in pain education to ensure that health care professionals are proficient in assessing and managing pain. The purpose of this survey was to determine the extent of pain education in current Doctorate of Physical Therapy schools in the United States, including how pain is incorporated into the curriculum, the amount of time spent teaching about pain, and the resources used to teach about pain. The survey consisted of 10 questions in the following subject areas: basic science mechanisms and concepts about pain, pain assessment, pain management, and adequacy of pain curriculum. The overall response was 77% (167/216) for the first series of responses of the survey (Question 1), whereas 62% completed the entire survey (Questions 2-10). The average contact hours teaching about pain was 31 ± 1.8 (mean ± standard error of the mean) with a range of 5 to 115 hours. The majority of schools that responded covered the science of pain, assessment, and management. Less than 50% of respondents were aware of the Institute of Medicine report on pain or the International Association for the Study of Pain guidelines for physical therapy pain education. Only 61% of respondents believed that their students received adequate education in pain management. Thus, this survey demonstrated how pain education is incorporated into physical therapy schools and highlighted areas for improvement such as awareness of recent educational advancements. This article demonstrates how pain education is incorporated into physical therapy curricula within accredited programs. Understanding the current structure of pain education in health professional curriculum can serve as a basis to determine if recent publications of guidelines and competencies impact education.

    Full Text Available Clinicians should be aware of new developments to familiarize themselves with pharmacokinetic and pharmacodynamic characteristics of new anticoagulant agents to appropriately and safely use them. For the moment, cardiologists and other clinicians also require to master currently available drugs, realizing the mechanism of action, side effects, and laboratory monitoring to measure their anticoagulant effects. Warfarin and heparin have narrow therapeutic window with high inter- and intra-patient variability, thereby the use of either drug needs careful laboratory monitoring and dose adjustment to ensure proper antithrombotic protection while minimizing the bleeding risk. The prothrombin time (PT and the activated partial thromboplastin time (aPTT are laboratory tests commonly used to monitor warfarin and heparin, respectively. These two tests depend highly on the combination of reagent and instrument utilized. Results for a single specimen tested in different laboratories are variable; this is mostly attributable to the specific reagents and to a much lesser degree to the instrument used. The PT stands alone as the single coagulation test that has undergone the most extensive attempt at assay standardization. The international normalized ratio (INR was introduced to ‘‘normalize’’ all PT reagents to a World Health Organization (WHO reference thromboplastin preparation standard, such that a PT measured anywhere in the world would result in an INR value similar to that which would have been achieved had the WHO reference thromboplastin been utilized. However, INRs are reproducible between laboratories for only those patients who are stably anticoagulated with vitamin K antagonists (VKAs (i.e., at least 6 weeks of VKA therapy, and are not reliable or reproducible between laboratories for patients for whom VKA therapy has recently been started or any other clinical conditions associated with a prolonged PT such as liver disease, disseminated

This increase parallels a decrease in infectious diseases within the same time period, while developing countries seem to exhibit the opposite effect, with less immune dysregulation and a higher prevalence of infectious disease. The “hygiene hypothesis”, proposed by Strachan in 1989, aimed to explain this peculiar generational rise in immune dysregulation. However, research over the past 10 years provides evidence connecting the commensal and symbiotic microbes (intestinal microbiota and parasitic helminths with immune development, expanding the hygiene hypothesis into the “microflora” and “old friends” hypotheses, respectively. There is evidence that parasitic helminths and commensal microbial organisms co-evolved with the human immune system and that these organisms are vital in promoting normal immune development. Current research supports the potential for manipulation of the bacterial intestinal microbiota to treat and even prevent immune dysregulation in the form of atopic disease and other immune-mediated disorders (namely inflammatory bowel disease and type 1 diabetes. Both human and animal model research are crucial in understanding the mechanistic links between these intestinal microbes and helminth parasites, and the human immune system. Pro-, pre-, and synbiotic, as well as treatment with live helminth and excretory/secretory helminth product therapies, are all potential

    In Japan, there are 27 Naikan medical institutions in which are included 5 clinics, 5 general hospitals and 17 mental hospitals. As for Naikan meditation center, there are 32 places. Generally, Naikan medical institutions and Naikan meditation center coexist in Japan. It is rare to see institutions for Naikan therapy in more north than Kanto area. Around Nara prefecture, which is Naikan therapy cradle, fairly numbers of Naikan meditation center are located. Surprisingly, no Naikan medical institutions are located. Naikan medical institutions and Naikan meditation center are distributed over the world. Total Naikan medical institutions are 32 and it only located in Japan and China. Total Naikan meditation center are 38 and 32 in Japan, 3 in Austria, 2 in Germany, and 1 in U.S.A. I would like to make suggestions as follows. At first, it is important to make cooperating with Naikan medical institution and Naikan meditation center. Also, it is necessary to enhance the technique ability of Naikan therapy. Secondary, we should guide medical workers to make understand useful of Naikan therapy as many as possible. Third, in order to do so, it is desirable to establish international Naikan Medical Association. Fourthly, it is necessary to systematize theory of the disease, therapeutic theory and therapeutic mechanism in Naikan therapy.

    Cardiogenic shock is often a devastating consequence of acute myocardial infarction (MI) and portends to significant mortality and morbidity. Despite improvements in expediting the time to treatment and enhancements in available medical therapy and reperfusion techniques, cardiogenic shock remains the most common cause of mortality following MI. Post-MI cardiogenic shock most commonly occurs as a consequence of severe left ventricular dysfunction. Right ventricular (RV) MI must also be considered. Mechanical complications including acute mitral regurgitation, ventricular septal rupture, and ventricular free-wall rupture can also lead to cardiogenic shock. Rapid diagnosis of cardiogenic shock and its underlying cause is pivotal to delivering definitive therapy. Intravenous vasoactive agents and mechanical support devices may temporize the patient's hemodynamic status until definitive therapy by percutaneous or surgical intervention can be performed. Despite prompt management, post-MI cardiogenic shock mortality remains high.

    OBJECTIVE: Although the etiology and pathogenesis of motor neuron disease is still unknown, there are many hypotheses on motor neuron mitochondrion, cytoskeleton structure and functional injuries. Thus, gene therapy of motor neuron disease has become a hot topic to apply in viral vector, gene delivery and basic gene techniques.DATA SOURCES: The related articles published between January 2000 and October 2006 were searched in Medline database and ISl database by computer using the keywords "motor neuron disease, gene therapy", and the language is limited to English. Meanwhile, the related references of review were also searched by handiwork. STUDY SELECTION: Original articles and referred articles in review were chosen after first hearing, then the full text which had new ideas were found, and when refer to the similar study in the recent years were considered first.DATA EXTRACTION: Among the 92 related articles, 40 ones were accepted, and 52 were excluded because of repetitive study or reviews.DATA SYNTHESIS: The viral vectors of gene therapy for motor neuron disease include adenoviral, adeno-associated viral vectors, herpes simplex virus type 1 vectors and lentiviral vectors. The delivery of them can be achieved by direct injection into the brain, or by remote delivery after injection vectors into muscle or peripheral nerves, or by ex vivo gene transfer. The viral vectors of gene therapy for motor neuron disease have been successfully developed, but the gene delivery of them is hampered by some difficulties. The RNA interference and neuroprotection are the main technologies for gene-based therapy in motor neuron disease. CONCLUSION : The RNA interference for motor neuron disease has succeeded in animal models, and the neuroprotection also does. But, there are still a lot of questions for gene therapy in the clinical treatment of motor neuron disease.

    Despite 30 years of its discovery, the ideal therapeutic regimen against Helicobacter pylori is still evasive. Clarithromycin-based standard triple therapy which has been considered the first line empirical therapy has been failing in many parts of the world, due to rising resistance against Clarithromycin, forcing the use of alternate regimens. In this context, we studied the local antibiotic resistance patterns against H. pylori and its impact on standard triple therapy in our region. All patients undergoing diagnostic upper endoscopy during the study period and detected to be positive for rapid urease test (RUT) underwent cultures of gastric mucosal specimens and had their antibiotic resistance patterns mapped out. Standard triple therapy was administered to those tested positive for H. pylori by RUT and eradication rates checked by urea breath test 4 weeks after the completion of treatment. Eradication rates with Clarithromycin-based standard triple therapy were suboptimal with a success of only (71.28%). H. pylori culture and antibiotic susceptibility studies showed high resistance to Clarithromycin (21.2%), Metronidazole (78.1%), and Levofloxacin (15%). However, the resistance to Amoxicillin (2.9%), Tetracycline (0%), and Rifabutin (4.5%) were low. Standard triple therapy is failing in our region due to high Clarithromycin resistance. We need to abandon empirical and blind triple therapy without post-treatment testing and devise alternate effective treatment strategies against H. pylori based on the local resistance patterns observed.

    The best management for small mucosal esophageal cancer is generally endoscopic mucosal resection. However, for submucosal cancer and extensive mucosal caner, either radical surgery or radiation seems to be an equally efficacious option. Radiation therapy concurrent with chemotherapy is more effective than radiation therapy alone for patients with unresectable esophageal cancer. The key drugs are cisplatin and 5-fluorouracil. However, for patients with poor performance status or for aged patients, radiation therapy alone is still a choice of treatment. Surgery has generally been indicated for patients with resectable esophageal cancer. However, outcomes of concurrent chemoradiation therapy may be comparable with those of surgery. Therefore, a prospective randomized study should be performed to determine the best management for patients with resectable esophageal cancer. The usefulness of intra-cavitary irradiation for esophageal cancer has not been clarified. A prospective randomized trial with a large number of patients is necessary to determine the effectiveness of intra-cavitary irradiation. The best management for patients with loco-regionally recurrent esophageal cancer after surgery has not been determined. Intensive therapy should be considered if the site of recurrence is limited and the time interval from surgery to recurrence is long. Chemotherapy is essential in the management of patients with small cell esophageal cancer. However, the best local therapy has not been determined. (author)

    resistance rate of clarithromycin and metronidazole was 4.2%. Both therapies achieved a high eradication rate for clarithromycin-resistant strains (100% vs 100%, respectively) and metronidazole-resistant strains (81.8% vs 95%, respectively) by intention-to-treat analysis. Ten-day reverse sequential therapy and standard sequential therapy are equally effective for H. Pylori eradication. The finding indicates that the sequence of antibiotics administered in sequential therapy does not influence the efficacy of the treatment. © 2014 John Wiley & Sons Ltd.

    Full Text Available Radioisotope therapy began in 1942 with the use of /sup 131/I for Graves disease and /sup 32/P for polycythemia vera. Local therapy with radioisotopes includes radiocolloids for malignant pleural and peritoneal effusions, intra-articular radiocolloids for chronic synovitis, intra-arterial radioactive microsphere for liver metastases, and intralymphatic administration for malignancies of the lymphatic system. The most widely practised use of radioisotopes for therapy is for the management of hyperthyroidism by /sup 131/I. Each school has developed its own treatment schedule for controlling the disease without producing too unacceptable an incidence of late hypothyroidism. /sup 131/I is also being used effectively for thyroid cancer, particularly at the Radiation Medicine Centre, BARC. There is hope that a new generation of radiolabelled compounds is round the corner for therapy. As in the case of radiopharmaceuticals for diagnosis, the shift has been from simple inorganic compounds to tailored organic ones. Radiolabelled monoclonal antibodies aimed against specific tumour antigens have already shown great promise. Another area of interest is the use of minute lipid spheroids (vesicles enclosing the radioactive drug which can be targeted to the tumour.

    2014-01-01

    SUMMARY Electroconvulsive therapy (ECT) is utilized worldwide for various severe and treatment-resistant psychiatric disorders. Research studies have shown that ECT is the most effective and rapid treatment available for elderly patients with depression, bipolar disorder and psychosis. For patients who suffer from intractable catatonia and neuroleptic malignant syndrome, ECT can be life saving. For elderly patients who cannot tolerate or respond poorly to medications and who are at a high risk for drug-induced toxicity or toxic drug interactions, ECT is the safest treatment option. Organic causes are frequently associated with late-life onset of neuropsychiatric conditions, such as parkinsonism, dementia and stroke. ECT has proven to be efficacious even when these conditions are present. During the next decade, research studies should focus on the use of ECT as a synergistic therapy, to enhance other biological and psychological treatments, and prevent symptom relapse and recurrence.

    Multiple sclerosis (MS) is a potentially disabling chronic autoimmune neurological disease that mainly affects young adults. Our understanding of the pathophysiology of MS has significantly advanced in the past quarter of a century. This has led to the development of many disease-modifying therapies (DMTs) that prevent exacerbations and new lesions in patients with relapsing remitting MS (RRMS). So far there is no drug available that can completely halt the neurodegenerative changes associated with the disease. It is the purpose of this review to provide concise information regarding mechanism of action, indications, side effects and safety of Food and Drug Administration and European Medicines Agency approved agents for MS, emerging therapies, and drugs that can be considered for off-label use in MS.

    Traditional therapies against cancer, chemo- and radiotherapy, have multiple limitations that lead to treatment failure and cancer recurrence. These limitations are related to systemic and local toxicity, while treatment failure and cancer relapse are due to drug resistance and self-renewal, properties of a small population of tumor cells called cancer stem cells(CSCs). These cells are involved in cancer initiation, maintenance, metastasis and recurrence. Therefore, in order to develop efficient treatments that can induce a longlasting clinical response preventing tumor relapse it is important to develop drugs that can specifically target and eliminate CSCs. Recent identification of surface markers and understanding of molecular feature associated with CSC phenotype helped with the design of effective treatments. In this review we discuss targeting surface biomarkers, signaling pathways that regulate CSCs self-renewal and differentiation, drug-efflux pumps involved in apoptosis resistance, microenvironmental signals that sustain CSCs growth, manipulation of mi RNA expression, and induction of CSCs apoptosis and differentiation, with specific aim to hamper CSCs regeneration and cancer relapse. Some of these agents are under evaluation in preclinical and clinical studies, most of them for using in combination with traditional therapies. The combined therapy using conventional anticancer drugs with CSCs-targeting agents, may offer a promising strategy for management and eradication of different types of cancers.

    Full Text Available Glioblastoma multiforme (GBM is one of the most frequently occurring tumors in the central nervous system and the most malignant tumor among gliomas. Despite aggressive treatment including surgery, adjuvant TMZ-based chemotherapy, and radiotherapy, GBM still has a dismal prognosis: the median survival is 14.6 months from diagnosis. To date, many studies report several determinants of resistance to this aggressive therapy: (1 O6-methylguanine-DNA methyltransferase (MGMT, (2 the complexity of several altered signaling pathways in GBM, (3 the existence of glioma stem-like cells (GSCs, and (4 the blood-brain barrier. Many studies aim to overcome these determinants of resistance to conventional therapy by using various approaches to improve the dismal prognosis of GBM such as modifying TMZ administration and combining TMZ with other agents, developing novel molecular-targeting agents, and novel strategies targeting GSCs. In this paper, we review up-to-date clinical trials of GBM treatments in order to overcome these 4 hurdles and to aim at more therapeutical effect than conventional therapies that are ongoing or are about to launch in clinical settings and discuss future perspectives.

    Full Text Available Carcinosarcomas (CS in gynecology are very infrequent and represent only 2–5% of uterine cancers. Despite surgical cytoreduction and subsequent chemotherapy being the primary treatment for uterine CS, the overall five-year survival rate is 30 ± 9% and recurrence is extremely common (50–80%. Due to the poor prognosis of CS, new strategies have been developed in the last few decades, targeting known dysfunctional molecular pathways for immunotherapy. In this paper, we aimed to gather the available evidence on the latest therapies for the treatment of CS. We performed a systematic review using the terms “uterine carcinosarcoma”, “uterine Malignant Mixed Müllerian Tumors”, “target therapies”, “angiogenesis therapy”, “cancer stem cell therapy”, “prognostic biomarker”, and “novel antibody-drug”. Based on our results, the differential expression and accessibility of epithelial cell adhesion molecule-1 on metastatic/chemotherapy-resistant CS cells in comparison to normal tissues and Human Epidermal Growth Factor Receptor 2 (HER2 open up new possibilities in the field of target therapy. Nevertheless, future investigations are needed to clarify the impact of these new therapies on survival rate and medium-/long-term outcomes.

    Cognitive therapy/cognitive behavior therapy was introduced into the field of psychiatry in the late 1980s in Japan, and the Japanese Association for Cognitive Therapy (JACT), founded in 2004, now has more than 1500 members. Along with such progress, awareness of the effectiveness of cognitive therapy/cognitive behavioral therapy has spread, not only among professionals and academics but also to the public. The Study Group of the Procedures and Effectiveness of Psychotherapy, funded by the Ministry of Health, Labor and Welfare, has conducted a series of studies on the effectiveness of cognitive therapy/cognitive behavior therapy since 2006 and shown that it is feasible for Japanese patients. As a result, in April 2010 cognitive therapy/cognitive behavior therapy for mood disorders was added to the national health insurance scheme in Japan. This marked a milestone in Japan's psychiatric care, where pharmacotherapy has historically been more common. In this article the authors review research on cognitive therapy/cognitive behavior therapy in Japan.

  6. CURRENT REPERFUSION THERAPY POSSIBILITIES IN MYOCARDIAL INFARCTION AND ISCHEMIC STROKE

    Directory of Open Access Journals (Sweden)

    E. V. Konstantinova

    2015-01-01

    Full Text Available Myocardial infarction and ischemic stroke remain to be of the greatest medical and social importance because of their high prevalence, disability, and mortality rates. Intractable thrombotic occlusion of the respective artery leads to the formation of an ischemic lesion focus in the tissue of the heart or brain. Emergency reperfusion serves to decrease a necrotic focus, makes its formation reversible, and reduces patient death rates. The paper considers main reperfusion therapy lines: medical (with thrombolytic drugs and mechanical (with primary interventions one and their combination in treating patients with acute myocardial and cerebral ischemia. Each reperfusion procedure is discussed in view of its advantages, disadvantages, available guidelines, and possibilities of real clinical practice. Tenecteplase is assessed in terms of its efficacy, safety, and capacities for bolus administration, which allows its use at any hospital and at the pre-hospital stage. Prehospital thrombolysis permits reperfusion therapy to bring much closer to the patient and therefore aids in reducing time to reperfusion and in salvaging as much the myocardial volume as possible. The rapidest recovery of myocardial and cerebral perfusion results in a decreased necrotic area and both improved immediate and late prognosis. The results of randomized clinical trials studying the possibilities of the medical and mechanical methods to restore blood flow are analyzed in the context of evidence-based medicine. The reason why despite the available contraindications, limited efficiency, and the risk of hemorrhagic complications, thrombolytic therapy remains the method of choice for prehospital reperfusion, an alternative to primary percutaneous coronary intervention (PCI if it cannot be carried out in patients with myocardial infarction at the stated time, and the only treatment ischemic stroke treatment that has proven its efficiency and safety in clinical trials is under

    In congenital diaphragmatic hernia (CDH), herniation of the abdominal organs into the fetal chest causes pulmonary hypoplasia and pulmonary hypertension, the main causes of neonatal mortality. As antenatal ultrasound screening improves, the risk of postnatal death can now be better predicted, allowing for the identification of fetuses that might most benefit from a prenatal intervention. Fetoscopic tracheal occlusion is being evaluated in a large international randomized controlled trial. We present the antenatal imaging approaches that can help identify fetuses that might benefit from antenatal therapy, and review the evolution of fetal surgery for CDH to date.

    Hemophilia A is a congenital, recessive, X-linked bleeding disorder that is managed with infusions of plasma-derived or recombinant factor (F) VIII. The primary considerations in FVIII replacement therapy today are the: 1) immunogenicity of FVIII concentrates, 2) role of longer-acting FVIII products, 3) prophylactic use of FVIII in children and adults with severe hemophilia A, and 4) affordability and availability of FVIII products. Improving patient outcomes by increasing the use of FVIII prophylaxis, preventing or eliminating FVIII inhibitors, and expanding access to FVIII concentrates in developing countries are the major challenges confronting clinicians who care for patients with hemophilia A.

    Full Text Available Elizabeth G Neal 1Matthew's Friends Clinics, Lingfield, UK, 2UCL Institute of Child Health, London, UK Abstract: The ketogenic diet (KD is a high-fat, restricted-carbohydrate regime, originally designed to mimic metabolic responses to fasting and has been used since the 1920s as a treatment for epilepsy. Modified variants of the KD include the addition of medium-chain triglyceride and less-restrictive modified Atkins and low glycemic index protocols. Scientifically proven as treatment for intractable seizures in children, these ketone-generating diets are increasingly also being used in adults. They are the treatment of choice in glucose transporter type 1 deficiency syndrome and pyruvate dehydrogenase deficiency. Evidence for the potential of KD therapy to be included within the treatment options for cancer and neurodegenerative disorders is more limited, albeit an exciting area of research with future clinical potential. This review discusses the key aspects of KD therapy, including the efficacy of treatments and clinical implementation.

    Full Text Available Renato Mantegazza, Silvia Bonanno, Giorgia Camera, Carlo AntozziDepartment of Neuromuscular Diseases and Neuroimmunology, Fondazione Istituto Neurologico Carlo Besta, Milan, ItalyAbstract: Myasthenia gravis (MG is an autoimmmune disease in which autoantibodies to different antigens of the neuromuscular junction cause the typical weakness and fatigability. Treatment includes anticholinesterase drugs, immunosuppression, immunomodulation, and thymectomy. The autoimmune response is maintained under control by corticosteroids frequently associated with immunosuppressive drugs, with improvement in the majority of patients. In case of acute exacerbations with bulbar symptoms or repeated relapses, modulation of autoantibody activity by plasmapheresis or intravenous immunoglobulins provides rapid improvement. Recently, techniques removing only circulating immunoglobulins have been developed for the chronic management of treatment-resistant patients. The rationale for thymectomy relies on the central role of the thymus. Despite the lack of controlled studies, thymectomy is recommended as an option to improve the clinical outcome or promote complete remission. New videothoracoscopic techniques have been developed to offer the maximal surgical approach with the minimal invasiveness and hence patient tolerability. The use of biological drugs such as anti-CD20 antibodies is still limited but promising. Studies performed in the animal model of MG demonstrated that several more selective or antigen-specific approaches, ranging from mucosal tolerization to inhibition of complement activity or cellular therapy, might be feasible. Investigation of the transfer of these therapeutic approaches to the human disease will be the challenge for the future.Keywords: myasthenia gravis, therapy, immunosuppression, thymectomy, plasmapheresis

    Although occupational therapists have been practicing in forensic settings for many years, there is a paucity of literature regarding the nature of this practice in Canada. The purpose of this study was to describe the practices of Canadian occupational therapists in forensic mental health. An online survey was designed based on the Canadian Practice Process Framework. Following purposive and snowball sampling, responses were analysed with descriptive statistics and content analysis. Twenty-seven clinicians responded (56% response rate). Respondents indicated commonalities in workplaces, client caseloads and practice challenges. The outstanding need in Canada to demonstrate client outcomes through the use of evaluation instruments reflects those practice gaps identified internationally. Education, advocacy and research are critical areas for the development of Canadian forensic occupational therapy. Although findings heavily reflect one provincial context and may not be generalizable to nonhospital settings, a number of priority areas were identified. Future efforts should clarify the role of forensic occupational therapy to stakeholders, and validate their contributions through research that evaluates intervention efficacy and meaningful outcomes.

    After 30 years of age physical capacity decreases with increasing age by 5-20% per decade. High physical activity in daily life as well as exercise training of endurance, strength, coordination and mobility can delay the functional and anatomical loss of muscle, bone, cartilage and connective tissue by more than 10 years. In recent years, numerous concepts have scientifically been proven in the exercise therapy of internal diseases; therefore, similar to drug treatment, cellular mechanisms of exercise training adaptation are known in detail. With this knowledge the type, dose and intensity of exercise training can be defined in such a way that the targeted use of physical training can achieve health benefits similar to the effects achieved by drugs. This applies to the cardiovascular system, lungs, cancer, metabolic diseases and the immune system. In exercise training therapy of patients, individual exercise programs should be defined in a way that the contents of endurance, strength, coordination and mobility address all health and personal concerns of the patient. For sustained effects and high motivation, the individual and disease-specific definition of exercise programs as well as regular monitoring are necessary. The prescription for movement as well as the prescriptions for sports rehabilitation and functional training incorporate important assistance in this context.

    Dialectical behavior therapy (DBT) is a comprehensive, evidence-based treatment for borderline personality disorder (BPD). The patient populations for which DBT has the most empirical support include parasuicidal women with borderline personality disorder (BPD), but there have been promising findings for patients with BPD and substance use disorders (SUDs), persons who meet criteria for binge-eating disorder, and depressed elderly patients. Although DBT has many similarities with other cognitive-behavioral approaches, several critical and unique elements must be in place for the treatment to constitute DBT. Some of these elements include (a) serving the five functions of treatment, (b) the biosocial theory and focusing on emotions in treatment, (c) a consistent dialectical philosophy, and (d) mindfulness and acceptance-oriented interventions.

    Full Text Available Helicobacter pylori infects approximately 50% of the world’s population and is a definitive cause of gastroduodenal disease (ie, gastritis, duodenal and gastric ulcers in children and adults. Four consensus conferences held around the globe have brought together clinicians, scientists, epidemiologists and health care economists to discuss the role of the gastric pathogen H pylori in human gastroduodenal disease. At each of these conferences, the overriding objective was to reach a consensus on the development of practical guidelines for the diagnosis and treatment of H pylori-infected individuals. However, it was not until the Canadian H pylori Consensus Conference, held in November 1997, that the issues of H pylori infection in children were addressed. Therapies for H pylori infection in children, presented in part at the First Canadian Paediatric H pylori Consensus Conference, held in Victoria, British Columbia, November 1998, are reviewed in this paper.

    Full Text Available ABSTRACTSevere sepsis and septic shock represent a major healthcare challenge. Much of the improvement in mortality associated with septic shock is related to early recognition combined with timely fluid resuscitation and adequate antibiotics administration. The main goals of septic shock resuscitation include intravascular replenishment, maintenance of adequate perfusion pressure and oxygen delivery to tissues. To achieve those goals, fluid responsiveness evaluation and complementary interventions - i.e. vasopressors, inotropes and blood transfusion - may be necessary. This article is a literature review of the available evidence on the initial hemodynamic support of the septic shock patients presenting to the emergency room or to the intensive care unit and the main interventions available to reach those targets, focusing on fluid and vasopressor therapy, blood transfusion and inotrope administration.

    Full Text Available Head and neck squamous cell carcinoma (HNSCC accounts for a large oncologic burden in the developing countries. In patients with locally advanced head and neck cancer multimodality treatment is warranted. Radiation therapy with concurrent chemotherapy has long been considered the standard for patients with disease involving the oropharynx, larynx and hypopharynx. However, addition of chemotherapy to radiotherapy increases treatment related toxicity by many folds and compliance rates decrease. In this context a systemic therapy, which when used concurrent with radiation with favorable toxicity profile is of great importance for improving disease control in locally advanced HNSCC. Anti-epithelial growth factor receptor targeted therapy emerged as a potential treatment option. In recent years many trials were conducted to find the optimum treatment option with the combination of these targeted agents. The initial trials showed excellent results with minimal morbidity and led to great enthusiasm across the globe to incorporate these regimens as a standard of care. However, subsequently many trials failed to maintain such results and now there is little agreement to the initial results achieved with these drugs. Based on the current evidence we cannot recommend the replacement of cisplatin with targeted therapy in concurrent setting. It may be considered in patients with altered renal parameters, hypersensitivity or intolerance to cisplatin. The addition of targeted therapy in addition to chemotherapy in the concurrent setting can’t also be recommended as the benefit is doubtful and is associated with a significant increase in toxicity.

    In the past decade, many guidance documents have been issued through collaboration of global organizations and regulatory authorities. Most of these are applicable to new products, but there is a risk that currently marketed products will not meet the new compliance standards during audits and inspections while companies continue to make changes through the product life cycle for continuous improvement or market demands. This discussion presents different strategies to bringing drug product marketing applications to meet current and emerging standards. It also discusses stability and method designs to meet process validation and global development efforts.

As understanding of disease behavior and pathogenesis has improved, the aims of those treating IPF have shifted from reversing the disease to slowing or preventing progression of this chronic fibrotic illness. It is to be hoped that by slowing disease progression, survival will be improved from the current dismal median of 3.5 years following diagnosis. In Europe and Asia, a milestone has recently been reached with the licensing of the first IPF-specific drug, pirfenidone. This review assesses the current treatment modalities available for IPF, including pirfenidone. It also turns an eye to the future and discusses the growing number of promising compounds currently in development that it is hoped, in time, will make their way into the clinic as treatments for IPF.Keywords: interstitial lung disease, pirfenidone, clinical trials, usual interstitial pneumonia, acute exacerbations

  7. Antifracture efficacy of currently available therapies for postmenopausal osteoporosis.

    2011-01-01

    Osteoporosis is a systemic bone disease characterized by low bone mass and bone mineral density, and deterioration of the underlying structure of bone tissue. These changes lead to an increase in bone fragility and an increased risk for fracture, which are the clinical consequences of osteoporosis. The classical triad for consideration in osteoporosis is morbidity, mortality and cost. Vertebral fracture is an important source of morbidity in terms of pain and spinal deformity. On the other hand, hip fracture is associated with the worst outcomes and is widely regarded as a life-threatening event in the elderly; it is the source of the bulk of the cost of the disease in contemporary healthcare. The prevention of osteoporosis-associated fracture should include fall prevention, calcium supplementation and lifestyle advice, as well as pharmacological therapy using agents with proven antifracture efficacy. The most commonly used osteoporosis treatments in Europe are the bisphosphonates alendronate, risedronate, ibandronate and zoledronic acid; the selective estrogen receptor modulator (SERM) raloxifene; teriparatide; and strontium ranelate. Recent additions include the biological therapy denosumab and the SERM bazedoxifene. In this review, we explore the antifracture efficacy of these agents with the aim of simplifying treatment decisions. These treatments can be broadly divided according to their mode of action. The antiresorptive agents include the bisphosphonates, the SERMs and denosumab, while the bone-forming agents include parathyroid hormone and teriparatide. Strontium ranelate appears to combine both antiresorptive and anabolic activities. We collated data on vertebral and hip fracture efficacy from the pivotal 3-year phase III trials, all of which had a randomized, double-blind, placebo-controlled design. The relative reductions in risk in the osteoporosis trials range from 30% to 70% for vertebral fracture and 30% to 51% for hip fracture. This translates into

    Inherited retinal degenerations (IRDs) encompass a large group of clinically and genetically heterogeneous diseases that affect approximately 1 in 3000 people (>2 million people worldwide) (Bessant DA, Ali RR, Bhattacharya SS. 2001. Molecular genetics and prospects for therapy of the inherited retinal dystrophies. Curr Opin Genet Dev 11: 307-316.). IRDs may be inherited as Mendelian traits or through mitochondrial DNA, and may affect the entire retina (e.g., rod-cone dystrophy, also known as retinitis pigmentosa, cone dystrophy, cone-rod dystrophy, choroideremia, Usher syndrome, and Bardet-Bidel syndrome) or be restricted to the macula (e.g., Stargardt disease, Best disease, and Sorsby fundus dystrophy), ultimately leading to blindness. IRDs are a major cause of severe vision loss, with profound impact on patients and society. Although IRDs remain untreatable today, significant progress toward therapeutic strategies for IRDs has marked the past two decades. This progress has been based on better understanding of the pathophysiological pathways of these diseases and on technological advances.

    Chemical peels have been time-tested and are here to stay. Alpha-hydroxy peels are highly popular in the dermatologist’s arsenal of procedures. Glycolic acid peel is the most common alpha-hydroxy acid peel, also known as fruit peel. It is simple, inexpensive, and has no downtime. This review talks about various studies of glycolic acid peels for various indications, such as acne, acne scars, melasma, postinflammatory hyperpigmentation, photoaging, and seborrhea. Combination therapies and treatment procedure are also discussed. Careful review of medical history, examination of the skin, and pre-peel priming of skin are important before every peel. Proper patient selection, peel timing, and neutralization on-time will ensure good results, with no side effects. Depth of the glycolic acid peel depends on the concentration of the acid used, the number of coats applied, and the time for which it is applied. Hence, it can be used as a very superficial peel, or even a medium depth peel. It has been found to be very safe with Fitzpatrick skin types I–IV. All in all, it is a peel that is here to stay.

    Short bowel syndrome (SBS) reflects a state of malabsorption that occurs due to loss of a significant portion of the small bowel. The pathophysiology of SBS is determined largely by the process of adaptation, which is the innate attempt by the remnant portions of the intestine to increase fluid and nutrient reabsorption. In recent years, emphasis has been placed on intestinal rehabilitation with multidisciplinary teams as a comprehensive approach to the management of patients with SBS. In our institution, the multidisciplinary team members include pediatric gastroenterologists, pediatric surgeons, pediatric dieticians, physical therapists, occupational therapists, neonatologists (especially for patients still under their care), transplant surgeons, transplant coordinators and social workers. Parenteral nutrition plays a significant role in the management of SBS, but its use is associated with many potential complications, including cholestatic liver disease. Fish oil-based lipid emulsions have shown promise in their ability to reverse and also prevent the development of cholestasis in these patients. Clinical trials have shown that growth factors and other trophic hormones facilitate the process of adaptation. The most significant impact has been shown with the use of glucagon-like peptide-2 and its analog (teduglutide). Surgical interventions remain an important part of the management of SBS to facilitate adaptation and treat complications. Intestinal transplantation is a last resort option when the process of adaptation is unsuccessful. This review article is intended to provide an overview of the conventional and emerging therapies for pediatric SBS.

    2009-01-01

    BACKGROUND: Following curative treatment for hepato-cellular carcinoma (HCC), 50%-90% of postoperative death is due to recurrent disease. Intra-hepatic recurrence is frequently the only site of recurrence. Thus, any neoadjuvant or adjuvant therapy, which can decrease or delay the incidence of intra-hepatic recurrence, or any cancer chemoprevention which can prevent a new HCC from developing in the liver remnant, will improve the results of liver resection. This article systematically reviewed the current evidence of neoadjuvant, adjuvant, and chemoprevention in partial hepatectomy of HCC. DATA SOURCES: Studies were identiifed by searching MEDLINE and PubMed databases for articles from January 1990 to November 2008 using the keywords"hepatocellular carcinoma", "hepatectomy", "adjuvant therapy", "neoadjuvant therapy", and "regional therapy". Additional papers and book chapters were identiifed by a manual search of the references from the key articles. RESULTS: Neoadjuvant transarterial chemoembolization or adjuvant regional transarterial chemotherapy± embolization+systemic chemotherapy did not add beneift. Both adjuvant transarterial radioembolization with 131I-lipiodol and adjuvant systemic interferon showed promising results. However, there were only a limited number of such studies.CONCLUSIONS: Further randomized controlled studies need to be carried out. Currently, there is no consensus on a standard neoadjuvant/adjuvant/chemoprevention therapy in partial hepatectomy for HCC.

    Full Text Available Abstract Background Management of glioblastoma multiforme (GBM has been difficult using standard therapy (radiation with temozolomide chemotherapy. The ketogenic diet is used commonly to treat refractory epilepsy in children and, when administered in restricted amounts, can also target energy metabolism in brain tumors. We report the case of a 65-year-old woman who presented with progressive memory loss, chronic headaches, nausea, and a right hemisphere multi-centric tumor seen with magnetic resonance imaging (MRI. Following incomplete surgical resection, the patient was diagnosed with glioblastoma multiforme expressing hypermethylation of the MGMT gene promoter. Methods Prior to initiation of the standard therapy, the patient conducted water-only therapeutic fasting and a restricted 4:1 (fat: carbohydrate + protein ketogenic diet that delivered about 600 kcal/day. The patient also received the restricted ketogenic diet concomitantly during the standard treatment period. The diet was supplemented with vitamins and minerals. Steroid medication (dexamethasone was removed during the course of the treatment. The patient was followed using MRI and positron emission tomography with fluoro-deoxy-glucose (FDG-PET. Results After two months treatment, the patient's body weight was reduced by about 20% and no discernable brain tumor tissue was detected using either FDG-PET or MRI imaging. Biomarker changes showed reduced levels of blood glucose and elevated levels of urinary ketones. MRI evidence of tumor recurrence was found 10 weeks after suspension of strict diet therapy. Conclusion This is the first report of confirmed GBM treated with standard therapy together with a restricted ketogenic diet. As rapid regression of GBM is rare in older patients following incomplete surgical resection and standard therapy alone, the response observed in this case could result in part from the action of the calorie restricted ketogenic diet. Further studies are needed

    Full Text Available Bronchial thermoplasty (BT is a recently developed treatment for patients with moderate-to-severe asthma. A few studies have suggested the clinical efficacy of this intervention. However, no study has evaluated the cost-effectiveness of BT compared to other alternative treatments for moderate-to-severe allergic asthma, which currently include omalizumab and standard therapy.To evaluate the cost-effectiveness of standard therapy, BT, and omalizumab for moderate-to-severe allergic asthma in the USA.A probabilistic Markov model with weekly cycles was developed to reflect the course of asthma progression over a 5-year time horizon. The study population was adults with moderate-to-severe allergic asthma whose asthma remained uncontrolled despite using high-dose inhaled corticosteroids (ICS, with or without long-acting beta-agonists [LABA]. A perspective of the health-care system was adopted with asthma-related costs as well as quality-adjusted life years (QALYs and exacerbations as the outcomes.For standard therapy, BT, and omalizumab, the discounted 5-year costs and QALYs were $15,400 and 3.08, $28,100 and 3.24, and $117,000 and 3.26, respectively. The incremental cost-effectiveness ratio (ICER of BT versus standard therapy and omalizumab versus BT was $78,700/QALY and $3.86 million/QALY, respectively. At the willingness-to-pay (WTP of $50,000/QALY and $100,000/QALY, the probability of BT being cost-effective was 9%, and 67%, respectively. The corresponding expected value of perfect information (EVPI was $155 and $1,530 per individual at these thresholds. In sensitivity analyses, increasing the costs of BT from $14,900 to $30,000 increased its ICER relative to standard therapy to $178,000/QALY, and decreased the ICER of omalizumab relative to BT to $3.06 million/QALY. Reducing the costs of omalizumab by 25% decreased its ICER relative to BT by 29%.Based on the available evidence, our study suggests that there is more than 60% chance that BT becomes

    Full Text Available Coenzyme Q10 (CoQ10 is a naturally occurring, lipid soluble, essential compound and is also known as ubiquinone. CoQ10 acts as an intermediate of the electron transport chain situated in membrane of mitochondria and vital for ATP production and cellular respiration. CoQ10 also serves as an intercellular antioxidant. All the clinical use of CoQ10 are based upon these two functions. CoQ10 levels are altered in a number of oncological as well as non-oncological diseases. Furthermore, recent data indicate that CoQ10 has an impact on the expression of many genes involved in metabolism, cellular transport, transcription control, and cell signaling, making CoQ10 a potent gene regulator. CoQ10 supplementation is useful in diseases associated with CoQ10 deficiency which includes primary and secondary CoQ10 deficiencies, fibromyalgia, diabetes mellitus, mitochondrial diseases, neurodegenerative diseases, cardiovascular disease, cancer, male infertility and periodontal disease. Clinical presentations of severe CoQ10 deficiency include severe infantile multisystemic disease, encephalomyopathy, isolated myopathy cerebellar ataxia and Leigh syndrome with growth retardation. Oral CoQ10 administration can correct CoQ10 deficiency since it increases CoQ10 tissue levels. CoQ10 therapy has no serious side effects in humans and new formulations have been developed that increase CoQ10 absorption and tissue distribution. Future trends involving CoQ10 in many diseases needs more clinical trials for better understanding of CoQ10 efficacy. [Int J Res Med Sci 2015; 3(4.000: 817-825

    Full Text Available Breast cancer is one of the most prevalent cancers amongst women in the world. Unfortunately, even after adequate treatment, some patients experience severe pain either due to disease progression or due to treatment related side effects. The persistent pain causes a negative physical and psychosocial impact on patients′ lives. Current rational pain management is patient-centred and requires a thorough psychological assessment. Usually adequate analgesia is achieved by adopting the WHO′s three step analgesic ladder. As the disease progresses, the pain experienced by the patient also increases. This necessitates the administration of opioids and adjuvant analgesics to the breast cancer patients experiencing severe pain. However, opioid use is associated with intolerable side effects like constipation, nausea, vomiting, fear of dependence, and tolerance. Concomitant medications are required to combat these unacceptable side effects. Adjuvant analgesics need to be added to provide adequate and satisfactory analgesia. These factors worsen the psychological state of patients and deteriorate their quality of life. Hence, there is a need to develop therapeutic modalities to provide adequate analgesia with minimum side effects. This review article focuses on the current treatments available for cancer pain management, their limitations, and novel targets and non-pharmacological measures under investigation which have the potential to produce a radical change in pain management measures for the breast cancer patients.

    Cerebral aneurysms occur in 5% of the adult population. Their most severe clinical manifestation is subarachnoid haemorrhage occurring in half of the patients. Morbidity and mortality of subarachnoid hemorrhage is relatively high. Stopping blood flow into the aneurysmal sac is the treatment objective. The basic techniques to achieve this are closing the aneurysmal neck with a clip - clipping - and the induction of intraaneurysmal thrombosis using platinum coils - coiling. Fusiform and giant aneurysms represent a technical challenge. The solution for indicated cases is the occlusion of the magistral artery along with a high-flow bypass. A new option is the use of special stents - flow-diverters - in unruptured aneurysms. The authors present the current view on the treatment of both ruptured and unruptured aneurysms. At the same time the authors focus on factors that influence the application of up-to-date knowledge on everyday activities in their departments.

    Full Text Available Hearing loss is one of the most frequent health issues in industrialized countries. The pathogenesis and molecular mechanisms of hearing loss are still unclear. Histone deacetylases (HDACs are emerging as key enzymes in many physiological processes, including chromatin remodeling, regulation of transcription, DNA repair, metabolism, genome stability and protein secretion. Recent studies indicated that HDACs are associated with the development and progression of hearing loss. Dysfunction of HDACs could promote the oxidative stress and aging in the inner ear. In light of considering the current stagnation in the development of therapeutic options, the need for new strategies in the treatment of hearing loss has never been so pressing. In this review, we will summarize the reported literatures for HDACs in hearing loss and discuss how HDAC family members show different performances for the possibility of process of diseases development. The possibility of pharmacological intervention on hearing loss opens a novel path in the treatment of hearing loss.

    Full Text Available Abstract Congenital hyperinsulinism (HI is an inappropriate insulin secretion by the pancreatic β-cells secondary to various genetic disorders. The incidence is estimated at 1/50, 000 live births, but it may be as high as 1/2, 500 in countries with substantial consanguinity. Recurrent episodes of hyperinsulinemic hypoglycemia may expose to high risk of brain damage. Hypoglycemias are diagnosed because of seizures, a faint, or any other neurological symptom, in the neonatal period or later, usually within the first two years of life. After the neonatal period, the patient can present the typical clinical features of a hypoglycemia: pallor, sweat and tachycardia. HI is a heterogeneous disorder with two main clinically indistinguishable histopathological lesions: diffuse and focal. Atypical lesions are under characterization. Recessive ABCC8 mutations (encoding SUR1, subunit of a potassium channel and, more rarely, recessive KCNJ11 (encoding Kir6.2, subunit of the same potassium channel mutations, are responsible for most severe diazoxide-unresponsive HI. Focal HI, also diazoxide-unresponsive, is due to the combination of a paternally-inherited ABCC8 or KCNJ11 mutation and a paternal isodisomy of the 11p15 region, which is specific to the islets cells within the focal lesion. Genetics and 18F-fluoro-L-DOPA positron emission tomography (PET help to diagnose diffuse or focal forms of HI. Hypoglycemias must be rapidly and intensively treated to prevent severe and irreversible brain damage. This includes a glucose load and/or a glucagon injection, at the time of hypoglycemia, to correct it. Then a treatment to prevent the recurrence of hypoglycemia must be set, which may include frequent and glucose-enriched feeding, diazoxide and octreotide. When medical and dietary therapies are ineffective, or when a focal HI is suspected, surgical treatment is required. Focal HI may be definitively cured when the partial pancreatectomy removes the whole lesion. By

    In addition to the routine therapy, the patients with lateral epicondylitis included into experimental group were subjected to a 12-week cell-stimulation therapy with low-intensity frequency-modulated electric current. The control group received the same routine therapy and sham stimulation (the therapeutic apparatus was not energized). The efficiency of this microcurrent therapy was estimated by comparing medical indices before therapy and at the end of a 12-week therapeutic course using a 10-point pain severity numeric rating scale (NRS) and Roles-Maudsley pain score. The study revealed high therapeutic efficiency of cell-stimulation with low-intensity electric current resulting probably from up-regulation of intracellular transmitters, interleukins, and prostaglandins playing the key role in the regulation of inflammation.

    2006-01-01

    Although insomnia is highly prevalent, sleep disturbances often go unrecognized and untreated. When insomnia is recognized, considerable emphasis has been placed on improving sleep onset; however, there is growing evidence that improving sleep maintenance is an equally important treatment goal. A MEDLINE literature search was performed using the search parameters "insomnia," "zolpidem," "zaleplon," "flurazepam," "estazolam," "quazepam," "triazolam," and "temazepam," as these agents are FDA-approved for the treatment of insomnia. Per reviewer comments, the search criteria was later expanded to include lorazepam. A literature search using the terms "trazodone" and "insomnia" was also performed, as this is the second-most commonly prescribed agent for treating insomnia. Sleep efficacy endpoints from randomized, placebo-controlled clinical trials in adult populations and key review articles published between 1975 and 2004 were included in this review. As only one randomized placebo-controlled trial evaluated trazodone use in primary insomnia, the trazodone search was expanded to include all clinical trials that evaluated trazodone use in insomnia. Relevant texts and other articles that evaluated side effect profiles of these agents were also included, one of which was published in January of 2005. In all publications, impact of treatment on sleep maintenance parameters (wake time after sleep onset, number of awakenings) and measures of next-day functioning were evaluated, in addition to sleep onset parameters (sleep latency, time to sleep onset/induction) and sleep duration data (total sleep time). Many of the currently available agents used to treat insomnia, including the antidepressant trazodone, the non-benzodiazepine hypnotics zolpidem and zaleplon, and some of the benzodiazepines, have not consistently demonstrated effectiveness in promoting sleep maintenance. Furthermore, the benzodiazepines with established sleep maintenance efficacy are associated with next

    2007-01-01

    Full Text Available Manual therapy has been an approach in the management of patients with various disorders dating back to ancient times and continues to play a significant role in current health care. The future role of manual therapy in health care is an important area of research. This paper reviews the history of manual therapy, examines the current literature related to the use of manual techniques (including manipulation, massage, and nerve manipulation, and discusses future research topics. The literature related to manual therapy has historically been anecdotal and theoretical, and current research tends to have a generic approach with broad definitions of manual therapy and inconsistencies in the classification of specific disorders. Systematic reviews of various types of manual therapy have differed on their conclusions regarding the effectiveness of this treatment modality. The current demand in health care for evidence-based practice necessitates a movement towards more specificity in the research of the effectiveness of manual therapy, with emphasis on specific patient signs and symptoms and specific manual techniques that result in effective care.

    2016-09-01

    Acromegaly is a chronic systemic disorder caused in the vast majority of cases by a GH-secreting pituitary adenoma and resulting in significant morbidity and mortality if left untreated. The treatment of choice is the trans-sphenoidal resection of the adenoma, and although 80% of patients with microadenomas or confined macroadenomas achieve biochemical remission, the surgical success rate for patients harboring tumors with extrasellar extension is below 50%. Thus, a considerable proportion of patients will require some form of adjuvant treatment. Acromegaly can be approached pharmacologically by inhibiting GH secretion by the tumor (somatostatin analogues, dopamine agonists) or by antagonizing GH actions at its target tissues (GH receptor antagonists). The primary pharmacological treatment of acromegaly is increasingly gaining acceptance by both physicians and patients. The decision to use primary pharmacological treatment has to take into account the clinical characteristics of the patient (presence of comorbidities that significantly increase the surgical risk) and the biological nature of the adenoma (tumor size and location), as well as other aspects such as the availability of a pituitary surgeon and the cost of medications. This review provides a critical summary and update of the pharmacological treatment of acromegaly focusing both, on well-established agents and strategies as well as on novel compounds that are currently being developed.

  10. Current Perspectives in Mesenchymal Stem Cell Therapies for Osteoarthritis

    2014-01-01

    Full Text Available Osteoarthritis (OA is a degenerative joint disease most commonly occurring in the ageing population. It is a slow progressive condition resulting in the destruction of hyaline cartilage followed by pain and reduced activity. Conventional treatments have little effects on the progression of the condition often leaving surgery as the last option. In the last 10 years tissue engineering utilising mesenchymal stem cells has been emerging as an alternative method for treating OA. Mesenchymal stem cells (MSCs are multipotent progenitor cells found in various tissues, most commonly bone marrow and adipose tissue. MSCs are capable of differentiating into osteocytes, adipocytes, and chondrocytes. Autologous MSCs can be easily harvested and applied in treatment, but allogenic cells can also be employed. The early uses of MSCs focused on the implantations of cell rich matrixes during open surgeries, resulting in the formation of hyaline-like durable cartilage. More recently, the focus has completely shifted towards direct intra-articular injections where a great number of cells are suspended and injected into affected joints. In this review the history and early uses of MSCs in cartilage regeneration are reviewed and different approaches in current trends are explained and evaluated.

    Full Text Available Background: Treatment of Helicobacter pylori as a major cause of gastric diseases is of utmost concern. We aimed to assess efficacy of triple therapy (amoxicillin, clarithromycin and pantoprazole plus probiotic yogurt (PY on eradication of H. pylori. Materials and Methods: Total 102 H. pylori positive patients were divided to 3 groups equally and randomly. For treatment of each group amoxicillin, clarithromycin and pantoprazole were used. Group A had additional PY and Group B ordinary low fat yogurt in their regimen as well. These groups were compared regarding treatment success.Results: Total number of 88 patients finished the treatment course. The most common experienced side effects were dysgeusia in groups A and B (25.8% and 32.3%, respectively, and dysgeusia with diarrhea and abdominal pain (30.8% in group C. Eradication rate was, respectively, 61.3%, 64.5% and 71.3% in group A, B and C of which difference was not statistically significant. However, the difference between 3 groups in regard to education level was statistically significant (p=0.005.Conclusion: PY enriched triple therapy has decreased side effects of antibiotics consumption; however, this has no impact on eradication of H. pylori. PY and triple therapy can be used concomitantly to increase the patient tolerance.

    One of the most significant health problems in the American continent in terms of human health, and socioeconomic impact is Chagas disease, caused by the protozoan parasite Trypanosoma cruzi. Infection was originally transmitted by reduviid insects, congenitally from mother to fetus, and by oral ingestion in sylvatic/rural environments, but blood transfusions, organ transplants, laboratory accidents, and sharing of contaminated syringes also contribute to modern day transmission. Likewise, Chagas disease used to be endemic from Northern Mexico to Argentina, but migrations have earned it global. The parasite has a complex life cycle, infecting different species, and invading a variety of cells - including muscle and nerve cells of the heart and gastrointestinal tract - in the mammalian host. Human infection outcome is a potentially fatal cardiomyopathy, and gastrointestinal tract lesions. In absence of a vaccine, vector control and treatment of patients are the only tools to control the disease. Unfortunately, the only drugs now available for Chagas' disease, Nifurtimox and Benznidazole, are relatively toxic for adult patients, and require prolonged administration. Benznidazole is the first choice for Chagas disease treatment due to its lower side effects than Nifurtimox. However, different strategies are being sought to overcome Benznidazole's toxicity including shorter or intermittent administration schedules-either alone or in combination with other drugs. In addition, a long list of compounds has shown trypanocidal activity, ranging from natural products to specially designed molecules, re-purposing drugs commercialized to treat other maladies, and homeopathy. In the present review, we will briefly summarize the upturns of current treatment of Chagas disease, discuss the increment on research and scientific publications about this topic, and give an overview of the state-of-the-art research aiming to produce an alternative medication to treat T. cruzi infection

    The Nuclear Medicine Global Initiative (NMGI) was formed in 2012 and consists of 13 international organizations with direct involvement in nuclear medicine. The underlying objectives of the NMGI are to promote human health by advancing the field of nuclear medicine and molecular imaging, encourage global collaboration in education, and harmonize procedure guidelines and other policies that ultimately lead to improvements in quality and safety in the field throughout the world. For its first project, the NMGI decided to consider the issues involved in the standardization of administered activities in pediatric nuclear medicine. It was decided to divide the final report of this project into 2 parts. Part 1 was published in this journal in the spring of 2015. This article presents part 2 of the final report. It discusses current standards for administered activities in children and adolescents that have been developed by various professional organizations. It also presents an evaluation of the current practice of pediatric nuclear medicine specifically with regard to administered activities as determined by an international survey of 313 nuclear medicine clinics and centers from 29 countries. Lastly, it provides recommendations for a path toward global standardization of the administration of radiopharmaceuticals in children.

    Objective Psychological treatments for posttraumatic stress disorder (PTSD) are usually delivered once or twice weekly over several months. It is unclear whether they can be successfully delivered over a shorter period of time. This clinical trial had two goals, (1) to investigate the acceptability and efficacy of a 7-day intensive version of cognitive therapy for PTSD, and (2) to investigate whether cognitive therapy has specific treatment effects by comparing intensive and standard weekly cognitive therapy with an equally credible alternative treatment. Method Patients with chronic PTSD (N=121) were randomly allocated to 7-day intensive or standard 3-month weekly cognitive therapy for PTSD, 3-month weekly emotion-focused supportive therapy, or a 14-week waitlist condition. Primary outcomes were PTSD symptoms and diagnosis as assessed by independent assessors and self-report. Secondary outcomes were disability, anxiety, depression, and quality of life. Measures were taken at initial assessment, 6 weeks and 14 weeks (post-treatment/wait). For groups receiving treatment, measures were also taken at 3 weeks, and follow-ups at 27 and 40 weeks after randomization. All analyses were intent-to-treat. Results At post-treatment/wait assessment, 73%, 77%, 43%, 7% of the intensive cognitive therapy, standard cognitive therapy, supportive therapy, and waitlist groups, respectively, had recovered from PTSD. All treatments were well tolerated and were superior to waitlist on all outcome measures, with the exception of no difference between supportive therapy and waitlist on quality of life. For primary outcomes, disability and general anxiety, intensive and standard cognitive therapy were superior to supportive therapy. Intensive cognitive therapy achieved faster symptom reduction and comparable overall outcomes to standard cognitive therapy. Conclusions Cognitive therapy for PTSD delivered intensively over little more than a week is as effective as cognitive therapy delivered

    2016-09-01

    Bladder urothelial cancers remain an important urologic cancer with limited treatment options in the locally advanced and metastatic setting. While neoadjuvant chemotherapy for locally advanced muscle-invasive cancers has shown overall survival benefit, clinical uptake in practice have lagged behind. Controversies surrounding adjuvant chemotherapy use are also ongoing. Systemic therapies for metastatic bladder cancer have largely used platinum-based therapies without effective standard second-line therapy options for those who fail, although vinflunine is approved in Europe as a second-line therapy based on a Phase III trial, and most recently, atezolizumab, a checkpoint inhibitor, was approved by the US FDA. Given increasing recognition of mutational signatures expressed in urothelial carcinomas, several promising agents with use of VEGF-targeted therapies, HER2-directed agents and immunotherapies with PD-1/PD-L1 antibodies in various settings are discussed herein.

    The paper presents for the first time a quantification of the photospheric electric current ribbon evolutions during an eruptive flare, accurately predicted by the standard 3D flare model. The standard flare model in 3D has been developed with the MHD code OHM, which models the evolution of an unstable flux rope. Through a series of paper, the model has been successful in explaining observational characteristics of eruptive flares, as well as the intrinsic 3D reconnection mechanism. Such a model also explains the increase of the photospheric currents as a consequence of the evolution of the coronal current layer where reconnection takes place. The photospheric footprints of the 3D current layer reveal a ribbon shape structure. In the present paper, the evolution of the current density is analyzed for the X-class flare that occurred on 15/02/2011 in AR 11158. We first describe the structural evolution of the high vertical current density regions derived with the UNNOFIT inversion code from magnetograms (HMI, e...

    2011-08-01

    As clinical forensic medicine (CFM) is not currently recognised as a speciality in the UK there are no nationally agreed mandatory standards for training forensic physicians in either general forensic (GFM) or sexual offence medicine (SOM). The General Medical Council (GMC), the medical regulator in the UK, has issued clear standards for training in all specialities recommending that "trainees must be supported to acquire the necessary skills and experience through induction, effective educational supervision, an appropriate workload and time to learn". In order to evaluate the current situation in the field of clinical forensic medicine, doctors who have recently (within the last two years) started working in the field "trainees" (n = 38), and trainers (n = 61) with responsibility for clinical and educational supervision of new trainees, were surveyed by questionnaire to gather their perceptions of how the relevant GMC standards are being met in initial on-the-job training. Telephone interviews were performed with eleven doctors working as clinical or medical directors to determine their views. It is clear that currently the quality of training in CFM is sub-standard and inconsistent and that the published standards, as to the minimum requirement for training that must be met by post-graduate medical and training providers at all levels, are not being met. The Faculty of Forensic and Legal Medicine (FFLM) needs to set explicit minimum standards which will comply with the regulator and work to pilot credentialing for forensic physicians. A number of recommendations are made for urgent FFLM development.

    2017-01-01

    The standard model of particle physics is our best description yet of fundamental particles and their interactions, but it is known to be incomplete. As yet undiscovered particles and interactions might exist. One of the most powerful ways to search for new particles is by studying processes known as flavour-changing neutral current decays, whereby a quark changes its flavour without altering its electric charge. One example of such a transition is the decay of a beauty quark into a strange quark. Here we review some intriguing anomalies in these decays, which have revealed potential cracks in the standard model—hinting at the existence of new phenomena.

    Imaging techniques and technology which were previously the domain of diagnostic medicine are becoming increasingly integrated and utilized in radiation therapy (RT) clinical practice. As such, there are a number of specific imaging topics that are highly applicable to modern radiation therapy physics. As imaging becomes more widely integrated into standard clinical radiation oncology practice, the impetus is on RT physicists to be informed and up-to-date on those imaging modalities relevant to the design and delivery of therapeutic radiation treatments. For example, knowing that, for a given situation, a fluid attenuated inversion recovery (FLAIR) image set is most likely what the physician would like to import and contour is helpful, but may not be sufficient to providing the best quality of care. Understanding the physics of how that pulse sequence works and why it is used could help assess its utility and determine if it is the optimal sequence for aiding in that specific clinical situation. It is thus important that clinical medical physicists be able to understand and explain the physics behind the imaging techniques used in all aspects of clinical radiation oncology practice. This session will provide the basic physics for a variety of imaging modalities for applications that are highly relevant to radiation oncology practice: computed tomography (CT) (including kV, MV, cone beam CT [CBCT], and 4DCT), positron emission tomography (PET)/CT, magnetic resonance imaging (MRI), and imaging specific to brachytherapy (including ultrasound and some brachytherapy specific topics in MR). For each unique modality, the image formation process will be reviewed, trade-offs between image quality and other factors (e.g. imaging time or radiation dose) will be clarified, and typically used cases for each modality will be introduced. The current and near-future uses of these modalities and techniques in radiation oncology clinical practice will also be discussed. Learning

    Full Text Available Objective: Diabetes has gradually emerged as one of the most serious public health problems in our country. This underlines the need for timely disease detection and decisive therapeutic intervention. This prospective cross-sectional observational study aims at analyzing the utilization pattern of antidiabetic agents in a remote North-East Indian tertiary care teaching hospital in the perspective of current standard treatment guidelines. Materials and Methods: Diabetic patients receiving antidiabetic medication, both as outpatients and inpatients in our hospital over a period of 12 months (May 2013–May 2014, were included in this study. The data obtained were sorted and analyzed on the basis of gender, type of therapy, and hospital setting. Results: A total of 310 patients were included in the study. Metformin was the single most frequently prescribed antidiabetic agent (66.8% followed by the sulfonylureas group (37.4%. Insulin was prescribed in 23.2% of the patients. Combination antidiabetic drug therapy (65.1% was used more frequently than monotherapy (34.8%. The use of biguanides (P < 0.0001 and sulfonylureas (P = 0.02 in combination was significant as compared to their use as monotherapy. A total of 48% of all antidiabetic combinations used, comprised metformin and sulfonylureas (n = 96. Insulin use was significantly higher as monotherapy and in inpatients (P< 0.0001. The utilization of drugs from the National List of Essential Medicines was 51.2%, while 11% of antidiabetics were prescribed by generic name. Conclusion: The pattern of utilization largely conforms to the current standard treatment guidelines. Increased use of generic drugs is an area with scope for improvement.

    In the process of working out and implementing standardization of acupuncture-moxibustion (acu-moxi) therapy, the issue of intellectual property rights has been frequently involved. Whether is the standardization inevitably involved in intellectual property rights? A reasonable answer to this question is definitely of important realistic guiding value and significance for acu-moxi standardization work. For this reason, authors of the present paper sum up historical development of correlation between acu-moxi standardization and intellectual property rights, and fully analyze the related causes under the conditions of knowledge economy from 1) increasing protection of acu-moxi intellectual property rights, 2) intrinsic requirements for raising the standardization level of acu-moxi, 3) profits drive of the intellectual property rights owners, and 4) increasing impetuous international economic trade competition.

The purpose of this pilot randomized control study was to prospectively compare planar and functional ROM, compliance, pain, enjoyment, and exertion in pediatric burn patients receiving two types of rehabilitation therapy. Seventeen school-aged children with 31 affected limbs who demonstrated limited shoulder ROM from burn injury were randomized to receive exercises using either standard therapy ROM activities (ST) or interactive videogame therapy (VGT). Patients received 3 weeks of the designated therapy intervention twice daily. They were then given a corresponding home program of the same type of therapy to perform regularly for 6 months. Standard goniometry and three-dimensional motion analysis during functional tasks were used to assess ROM. Measures were taken at baseline, 3 weeks, 3 months, and 6 months. Pain was measured before and after each treatment session during the 3-week intervention. There was no difference in compliance, enjoyment, or exertion between the groups. Patients in both the ST and VGT groups showed significant improvement in shoulder flexion (P < .001), shoulder abduction (P <.001), shoulder external rotation (P = .01), and elbow flexion (P = .004) ROM from baseline to 6 months as measured with goniometry. Subjects also showed significant gains in elbow flexion (P = .04) during hand to head and shoulder flexion (P = .04) during high reach. There was no difference in ROM gains between the groups. Within group comparison showed that the VGT group had significantly more recovery of ROM during the first 3 weeks than any other timeframe in the study, whereas ST had most gains at 3 months. There was a significant difference between the groups in the subjects' pain response. ST subjects

    Standardized terminology and digital sources of evidence are essential for evidence-based practice. Dieticians desire concise and consistent documentation of nutrition diagnoses, interventions and outcomes that will be fit for electronic health records. Building on more than 5 years of work to generate the Nutrition Care Process and Model as a road map to quality nutrition care and outcomes, and recognizing existing standardized languages serving other health professions, a task force of the American Dietetic Association (ADA) has begun to develop and disseminate standardized nutrition language. This paper will describe the group's working logic model, the Nutrition Care Process, and the current status of the nutrition language with comparisons to nursing process and terminology.

    Cancer metastasis accounts for the high mortality of many types of cancer. Owing to the unique advantages of high specificity and minimal invasiveness, photothermal therapy (PTT) has been evidenced with great potential in treating cancer metastasis. In this review, we outline the current approaches of PTT with respect to its application in treating metastatic cancer. PTT can be used alone, guided with multimodal imaging, or combined with the current available therapies for effective treatment of cancer metastasis. Numerous types of photothermal nanotherapeutics (PTN) have been developed with encouraging therapeutic efficacy on metastatic cancer in many preclinical animal experiments. We summarize the design and performance of various PTN in PTT alone and their combinational therapy. We also point out the lacking area and the most promising approaches in this challenging field. In conclusion, PTT or their combinational therapy can provide an essential promising therapeutic modality against cancer metastasis.

    Chronic hepatitis C virus (HCV) infection affects 80-160 million people worldwide and is one of the leading causes of chronic liver disease. It is only a few years ago that standard treatment regimes were based on pegylated interferon alpha and ribavirin. However, treatment of HCV has undergone a revolutionary change in recent years. The admission of the nucleotide polymerase inhibitor Sofosbuvir enabled an interferon-free regimen with direct antiviral agents (DAA). Meanwhile seven DAAs are available and can be applied in several combinations for 8 to 24 wk depending on HCV genotype and patient characteristics such as cirrhosis and chronic renal failure. High rates of sustained virological response (SVR) rates can be achieved with these novel drugs. Even in difficult to treat populations such as patients with liver cirrhosis, HCV-human immunodeficiency virus co-infections, after liver transplantion, or with chronic kidney disease comparable high rates of SVR can be achieved. The anticipated 2nd generation DAAs are strikingly effective in patients so far classified as difficult to treat including decompensated liver cirrhosis or post-transplant patients. These 2nd generations DAAs will have higher resistance barriers, higher antiviral effects and a pan-genotypic spectrum. This review highlights the current state of the art of antiviral treatment in hepatitis C and gives an outlook for upcoming therapies. PMID:26839638

    Full Text Available The treatment of hypogonadism in men is of great interest to both patients and providers. There are a number of testosterone formulations currently available and several additional formulations under development. In addition, there are some lesser-used alternative therapies for the management of male hypogonadism, which may have advantages for certain patient groups. The future of hypogonadism therapy may lie in the development of selective androgen receptor modulators that allow the benefits of androgens whilst minimizing unwanted side effects.

    Full Text Available Abstract Purpose To investigate repositioning accuracy in particle radiotherapy in 6 degrees of freedom (DOF and intensity-modulated radiotherapy (IMRT, 3 DOF for two immobilization devices (Scotchcast masks vs thermoplastic head masks currently in use at our institution for fractionated radiation therapy in head and neck cancer patients. Methods and materials Position verifications in patients treated with carbon ion therapy and IMRT for head and neck malignancies were evaluated. Most patients received combined treatment regimen (IMRT plus carbon ion boost, immobilization was achieved with either Scotchcast or thermoplastic head masks. Position corrections in robotic-based carbon ion therapy allowing 6 DOF were compared to IMRT allowing corrections in 3 DOF for two standard immobilization devices. In total, 838 set-up controls of 38 patients were analyzed. Results Robotic-based position correction including correction of rotations was well tolerated and without discomfort. Standard deviations of translational components were between 0.5 and 0.8 mm for Scotchcast and 0.7 and 1.3 mm for thermoplastic masks in 6 DOF and 1.2 - 1.4 mm and 1.0 - 1.1 mm in 3 DOF respectively. Mean overall displacement vectors were between 2.1 mm (Scotchcast and 2.9 mm (thermoplastic masks in 6 DOF and 3.9 - 3.0 mm in 3 DOF respectively. Displacement vectors were lower when correction in 6 DOF was allowed as opposed to 3 DOF only, which was maintained at the traditional action level of > 3 mm for position correction in the pre-on-board imaging era. Conclusion Setup accuracy for both systems was within the expected range. Smaller shifts were required when 6 DOF were available for correction as opposed to 3 DOF. Where highest possible positioning accuracy is required, frequent image guidance is mandatory to achieve best possible plan delivery and maintenance of sharp gradients and optimal normal tissue sparing inherent in carbon ion therapy.

    Full Text Available Introduction & Objective: Some studies have reported successful eradication rates using se-quential therapy but more recent studies performed in Asia did not find a similar benefit. Due to inconsistencies in the comparison of standard triple drugs therapy and sequential regimen, in the previous researches we decided to compare these treatments in Persian patients. Materials & Methods: This study is a randomized clinical trial, performed in one hundred and forty patients suffering from dyspepsia with indication for H. pylori eradication between No-vember 2010 and March 2012.Patients were randomized in two equal groups. The patients in the first group (standard were treated by omeprazole capsule 20 mg BID, amoxicillin cap-sule 1 gr BID, clarithromycin tablet 500mg BID for 14 days; while the patients in the second group (sequential were treated by omeprazole capsule 20 mg for 10 days, amoxicillin cap-sule 1 gr BID for 5 days, then clarithromycin tablet 500 mg and tinidazole tablet 500 mg BID for other 5 days. 4-6 weeks after the treatment, we compared the eradication of H.pylori be-tween the two groups by urease breathe test with C14. Results: H. pylori infection was successfully cured in 57/70 (81.43% with a 10-day sequen-tial therapy, in 60/70 (85.75% with the standard fourteen-day triple therapy, respectively. Conclusion: We detected no significant differences between the 10-day sequential eradication therapy for H. pylori and 14-day standard triple treatment among the patients.

    This paper summarises results from an evaluation of the adequacy and utility of the Australian Competency Standards for Entry-Level Occupational Therapists (OT AUSTRALIA, 1994a). It comprised a two-part study, incorporating an online survey of key national stakeholders (n = 26), and 13 focus groups (n = 152) conducted throughout Australia with occupational therapy clinicians, academics, OT AUSTRALIA association and Occupational Therapy Registration Board representatives, as well as university program accreditors. The key recommendations were that: (i) urgent revision to reflect contemporary practice, paradigms, approaches and frameworks is required; (ii) the standards should exemplify basic competence at graduation (not within two years following); (iii) a revision cycle of five years is required; (iv) the Australian Qualifications Framework should be retained, preceded by an introduction describing the scope and nature of occupational therapy practice in the national context; (v) access to the standards should be free and unrestricted to occupational therapists, students and the public via the OT AUSTRALIA (national) website; (vi) the standards should incorporate a succinct executive summary and additional tools or templates formatted to enable occupational therapists to develop professional portfolios and create working documents specific to their workplace; and (vii) language must accommodate contextual variation while striking an appropriate balance between providing instruction and encouraging innovation in practice.

    Full Text Available Background. ESWT has proven clinical benefit in dermatology and plastic surgery. It promotes wound healing and improves tissue regeneration, connective tissue disorders, and inflammatory skin diseases. However, a single treatment session or long intervals between sessions may reduce the therapeutic effect. The present study investigated the effects of fractionated repetitive treatment in skin microcirculation. Methods. 32 rats were randomly assigned to two groups and received either fractionated repetitive high-energy ESWT every ten minutes or placebo shock wave treatment, applied to the dorsal lower leg. Microcirculatory effects were continuously assessed by combined laser Doppler imaging and photospectrometry. Results. In experimental group, cutaneous tissue oxygen saturation was increased 1 minute after the first application and until the end of the measuring period at 80 minutes after the second treatment (P<0.05. The third ESWT application boosted the effect to its highest extent. Cutaneous capillary blood flow showed a significant increase after the second application which was sustained for 20 minutes after the third application (P<0.05. Placebo group showed no statistically significant differences. Conclusions. Fractionated repetitive extracorporeal shock wave therapy (frESWT boosts and prolongs the effects on cutaneous hemodynamics. The results indicate that frESWT may provide greater benefits in the treatment of distinct soft tissue disorders compared with single-session ESWT.

  14. Current considerations concerning endodontically treated teeth: alteration of hard dental tissues and biomechanical properties following endodontic therapy.

    2009-01-01

    The aim of this general article is to present an overview of the current knowledge about composition and structural changes and also about specific biomechanical alterations related to vitality loss or endodontic therapy. For a long time, these issues have been controversially approached from a clinical standpoint and are therefore still confusing for many practitioners. Vitality loss or endodontic procedures seem to induce only negligible changes in hard dental tissue moisture. Physico-chemical properties of dentin can be modified by some of the endodontic chemical products used for chemo-mechanical debridement. On the other hand, tooth biomechanical behavior is affected, since tooth strength is reduced proportionally to coronal tissue loss, due to either pre-existent carious/non-carious lesions or cavity acces preparation, besides restorative procedures. The related literature shows the lack of accepted clinical standards and consensus regarding the optimal way of approaching the specific tooth biomechanics following endodontic therapy.

    Chronic Achilles tendinopathy has been described as the most common overuse injury in sports medicine. Several treatment modalities such as activity modification, heel lifts, arch supports, stretching exercises, nonsteroidal anti-inflammatories, and eccentric loading are known as standard treatment mostly without proven evidence. After failed conservative therapy, invasive treatment may be considered. Extracorporeal shock wave therapy (ESWT) has been successfully used in soft-tissue pathologies like lateral epicondylitis, plantar fasciitis, tendinopathy of the shoulder and also in bone and skin disorders. Conclusive evidence recommending ESWT as a treatment for Achilles tendinopathy is still lacking. In plantar fasciitis as well as in calcific shoulder tendinopathy shock wave therapy is recently the best evaluated treatment option. This article analysis the evidence based literature of ESWT in chronic Achilles tendinopathy. Recently published data have shown the efficacy of focused and radial extracorporeal shock wave therapy.

    {sup 177}Lu-based PSMA-targeted therapy appears to be a promising treatment for advanced PCA. However, lessons should be learned from PRRT of neuroendocrine tumours, which was referred to as a ''promising'' tool for 15 years before the advent of evidence-based comparative studies. This experience strongly suggests that the communities involved with PSMA-targeted therapy, namely nuclear medicine, urology, radiochemistry, and medical physics, should capitalize without delay on the great opportunity to conduct well-designed prospective studies. Doing so should advance this modality from the proof-of principle stage to the potential standard-of-Care-stage. From our perspective, crucial components of this process are: - Harmonization of therapy protocols - Implementation of a patient selection algorithm into clinical routine - Standardization of toxicity assessment - Establishment of standardized dosimetry protocols to assess safety and efficacy - Transfer of expertise in PSMA therapy throughout Europe - Regulatory approval of {sup 177}Lu-PSMA-targeted compounds.

    1993-01-01

    A study of the transport and loss of ions in the earth's quiet time ring current, in which the standard radial diffusion model developed for the high-energy radiation belt particles is compared with the measurements of the lower-energy ring current ions, is presented. The data set provides ionic composition information in an energy range that includes the bulk of the ring current energy density, 1-300 keV/e. Protons are found to dominate the quiet time energy density at all altitudes, peaking near L of about 4 at 60 keV/cu cm, with much smaller contributions from O(+) (1-10 percent), He(+) (1-5 percent), and He(2+) (less than 1 percent). A minimization procedure is used to fit the amplitudes of the standard electric radial diffusion coefficient, yielding 5.8 x 10 exp -11 R(E-squared)/s. Fluctuation ionospheric electric fields are suggested as the source of the additional diffusion detected.

    2012-11-01

    Currently, 29 states, the District of Columbia, and Puerto Rico have instituted a renewable portfolio standard (RPS). An RPS sets a minimum threshold for how much renewable energy must be generated in a given year. Each state policy is unique, varying in percentage targets, timetables, and eligible resources. This paper examines state experience with implementing renewable portfolio standards that include energy efficiency, thermal resources, and non-renewable energy and explores compliance experience, costs, and how states evaluate, measure, and verify energy efficiency and convert thermal energy. It aims to gain insights from the experience of states for possible federal clean energy policy as well as to share experience and lessons for state RPS implementation.

    Antiplatelet therapies play a central role in reducing the risk of cardiovascular events such as myocardial infarction and stroke. While aspirin, a cyclo-oxygenase-1 inhibitor has been the cornerstone of antithrombotic treatment for several decades, P2Y12 receptor inhibitors cangrelor, clopidogrel, prasugrel, and ticagrelor and protease-activated receptor-1 antagonist vorapaxar, have emerged as additional therapies to reduce the risk of recurrent cardiovascular events in high-risk patients. Recent clinical trials evaluating the role of these agents and major society guideline updates for use of antiplatelet therapies for secondary prevention of cardiovascular events will be examined. The latest studies regarding the appropriate duration of dual antiplatelet therapy after percutaneous coronary intervention will be presented. The current state of genetic and platelet function testing will be reviewed.

    Biologic therapy represents a relatively new class of drugs which have revolutionized the treatment of psoriasis and are used with increasing frequency in order to control this chronic, systemic inflammatory disease. However, it is unclear what role there is for combination therapy of biologics with traditional topical agents. The purpose of this article is to assess the literature on the role of topical agents as adjuvants to biological treatments in the treatment of psoriasis and identify areas for further research. A MEDLINE search was performed in order to identify English-language publications from 1996 to 2014 examining combination biologic therapy with topical medications in the treatment of psoriasis. Data from these clinical studies are summarized and the outcomes are discussed. In general, the addition of adjuvant topical therapy to systemic biologic therapy allowed for a reduction in dosage and side effects of both agents, maintenance of initial response to biologics, treatment of recalcitrant lesions in partial responders, and potential acceleration of response to biologic therapies. The current data, though limited, suggest that using topical therapies as adjunct treatment to biologics is a well tolerated and effective means of controlling psoriasis and improving quality of life for patients. However, the treating physician should remain attentive to signs of adverse events and seek opportunities to reduce the dose or treatment frequency during chronic use.

    As one of the most promising medical metal implants, magnesium (Mg) or its alloys have shown significant advantages over other candidates attributed to not only their excellent biodegradability and suitable mechanical properties but also their osteopromotive effects for bone applications. Prior to approval mandated by the governmental regulatory body, the access to the medical market for Mg-based implants requires a series of testing for assurance of their safety and efficacy via preclinical evaluations and clinical tests including phase 1 and 2 evaluations, and phase 3 of multi-center randomized double blind and placebo-controlled clinical trials. However, as the most widely used protocols for biosafety evaluation of medical devices, current ISO 10993 standards should be carefully reevaluated when directly applying them to predict potential health risks of degradable Mg based biomaterials via cytotoxicity tests due to the huge gap between in vitro and in vivo conditions. Therefore, instead of a direct adoption, modification of current ISO standards for in vitro cytotoxicity test is desirable and justified. The differences in sensitivities of cells to in vitro and in vivo Mg ions and the capability of in vivo circulation system to dilute local degradation products were fully considered to propose modification of current ISO standards. This paper recommended a minimal 6 times to a maximal 10 times dilution of extracts for in vitro cytotoxicity test specified in ISO 10993 part 5 for pure Mg developed as potential orthopedic implants based on literature review and our specifically designed in vitro and in vivo tests presented in the study. Our work may contribute to the progress of biodegradable metals involved translational work. Copyright © 2015 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Background: Hepatitis D virus (HDV infection is characterized by rapidly progressive liver disease with adverse prognosis in most patients. Although interferon is the only approved anti-HDV therapy, evidence regarding the efficacy and safety of its various regimens is either old or scattered. Materials and Methods: We searched systematically Medline, EMBASE, Scopus, the Cochrane Central Register of Controlled Trials, and ISI. The studies that evaluated treatment of chronic HDV infection with standard or pegylated interferon for at least 48 weeks were identified. Our inclusion criteria were positive anti-HDV antibody for 6 months and positive HDV-PCR at the start of study. We performed a meta-analysis for proportions using the arcsine transformation in random effects model. Sustained virological response (SVR rate (negative Polymerase chain reaction (PCR 6 months after cessation of therapy was the end point of interest. Results: Data were abstracted from 14 studies containing 227 chronic HDV-infected patients who received standard or pegylated interferon alpha-2a or -2b. Twenty-one and 30 patients of 71 and 156 who received standard or peginterferon, respectively, beyond 48 weeks achieved SVR. Pooled SVR rates were 29% [95% confidence interval (CI 19; 41] and 19% (95% CI 10; 29, respectively. The rates of treatment withdrawal were similar. Conclusion: Our systematic review indicates that the literature lacks sufficient evidence to establish precise recommendations for treatment of HDV infection. Meta-analysis of these studies shows that standard dose of peginterferon is more effective than high dose of standard interferon as anti-HDV therapy.

    Narrative exposure therapy (NET) applied by Neuner et al. on populations affected by war and natural disaster is compared to research data and intervention strategies developed by others. Questions are raised about the cultural sensitivity of Neuner's diagnostic instruments, the reductionist focus on PTSD which does not sufficiently take into account the complex after effects of trauma and the comprehensive psychosocial needs of affected populations. Currently available data do not yet provide convincing evidence that NET is effective or superior to other intervention strategies.

    In this work we report on the development of Giant Magnetoresistive (GMR) sensors for off-line current measurements in standard integrated circuits. An ASIC has been specifically designed and fabricated in the well-known AMS-0.35 μm CMOS technology, including the electronic circuitry for sensor interfacing. It implements an oscillating circuit performing a voltage-to-frequency conversion. Subsequently, a fully CMOS-compatible low temperature post-process has been applied for depositing the GMR sensing devices in a full-bridge configuration onto the buried current straps. Sensitivity and resolution of these sensors have been investigated achieving experimental results that show a detection sensitivity of about 100 Hz/mA, with a resolution of about 5 μA.

    Digital modeling of human anatomy has become increasingly important and relies on well-documented quantitative anatomy literature. This type of documentation is common for the spine and pelvis; however, significant issues exist due to the lack of standardization in measurement and technique. Existing literature on quantitative anatomy for the spine and pelvis of white adults (aged 18-65 years, separated into decadal categories) was reviewed from the disciplines of anatomy, manipulative therapy, anthropometrics, occupational ergonomics, biomechanics and forensic science. The data were unified into a single normative model of the sub-axial spine. Two-dimensional orthographic drawings were produced from the 590 individual measurements identified, which informed the development of a 3D digital model. A similar review of full range of motion data was conducted as a meta-analysis and the results were applied to the existing model, providing an inter-connected, articulated digital spine. During these data analysis processes several inconsistencies were observed accompanied by an evidential lack of standardization with measurement and recording of data. These have been categorized as: anatomical terminology; scaling of measurements; measurement methodology, dimension and anatomical reference positions; global coordinate systems. There is inconsistency in anatomical terminology where independent researchers use the same terms to describe different aspects of anatomy or different terms for the same anatomy. Published standards exist for measurement methods of the human body regarding spatial interaction, anthropometric databases, automotive applications, clothing industries and for computer manikins, but none exists for skeletal anatomy. Presentation of measurements often lacks formal structure in clinical publications, seldom providing geometric reference points, therefore making digital reconstruction difficult. Published quantitative data does not follow existing

    The introduction of evidence-based therapy standards in child and adolescent rehabilitation of the German statutory pension insurance scheme (Deutsche Rentenversicherung Bund, 2011) was accompanied by a user survey that gave the participating rehabilitation centres the opportunity to comment on the new therapy standards and to suggest modifications.The survey questionnaire encompassed various topics related to the therapy standards, amongst them quality, comprehensibility, and acceptance, evaluation of feedback, and reasons for noncompliance with therapy standard requirements. For each of the 3 indications, a separate questionnaire was applied to assess modification suggestions regarding KTL therapy elements, the minimum percentage of patients to be treated accordingly, and the minimum duration of therapeutic procedures for each evidence-based treatment module. Responses from 14 rehab centres (return rate 54%) were obtained and analyzed.According to the majority of the responding rehabilitation centres, the therapy standards for child and adolescent rehabilitation fulfilled the quality features of topicality, multidisciplinarity, and relevance for routine rehabilitative practice. The degree of empirical grounding was evaluated more inconsistently. Difficulties with coding of KTL therapy elements were cited as the primary reasons for failing to comply with requirements in 2008.Exemplarily, the results of the user survey regarding the rehabilitative treatment of children and adolescents with obesity (age group: 8 years and older) are presented in detail.Concluding, the modifications to the therapy standards in child and adolescent rehabilitation introduced on the basis of the user survey are set out. © Georg Thieme Verlag KG Stuttgart · New York.

    Bejlin, V A; Kuksa, V I

    2001-01-01

    The review is devoted to the phenomenology of singlet quarks, which are singlets with respect to the SU(2), have hypercharges Y = -1/3 masses m > m sub t. It is shown, that experimental data on rare processes and the corresponding theoretical predictions of the Standard Model (SM) allow to invoke the SM extensions for the analysis of the phenomena stimulated by flavor changing neutral current. The extended matrix of standard and singlet quark mixing is constructed, the restriction on mixing angles and the estimate of low bound of singlet quark mass m sub D >= 0.5 TeV are obtained. Besides the direct observation the perspectives to increase the confidence level of the singlet quark existence are discussed. The cross-sections of nondiagonal production of singlet quark in pair with standard one in e sup - e sup + -, ep- and pp-bar-collisions are analyzed and the unique signature of such events is described. The model of up-singlet quark with the hypercharge Y sub U 2/3 and its applications to the physics of t-qu...

    2015-03-13

    Underlying cognitive declines in Alzheimer's disease (AD) are the result of neuron and neuronal process losses due to a wide range of factors. To date, all efforts to develop therapies that target specific AD-related pathways have failed in late-stage human trials. As a result, an emerging consensus in the field is that treatment of AD patients with currently available drug candidates might come too late, likely as a result of significant neuronal loss in the brain. In this regard, cell-replacement therapies, such as human embryonic stem cell- or induced pluripotent stem cell-derived neural cells, hold potential for treating AD patients. With the advent of stem cell technologies and the ability to transform these cells into different types of central nervous system neurons and glial cells, some success in stem cell therapy has been reported in animal models of AD. However, many more steps remain before stem cell therapies will be clinically feasible for AD and related disorders in humans. In this review, we will discuss current research advances in AD pathogenesis and stem cell technologies; additionally, the potential challenges and strategies for using cell-based therapies for AD and related disorders will be discussed.

  15. Current concepts in F18 FDG PET/CT-based Radiation Therapy planning for Lung Cancer

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available Radiation therapy is an important component of cancer therapy for early stage as well as locally advanced lung cancer. The use of F18 FDG PET/CT has come to the forefront of lung cancer staging and overall treatment decision-making. FDG PET/CT parameters such as standard uptake value and metabolic tumor volume provide important prognostic and predictive information in lung cancer. Importantly, FDG PET/CT for radiation planning has added biological information in defining the gross tumor volume as well as involved nodal disease. For example, accurate target delineation between tumor and atelectasis is facilitated by utilizing PET and CT imaging. Furthermore, there has been meaningful progress in incorporating metabolic information from FDG PET/CT imaging in radiation treatment planning strategies such as radiation dose escalation based on standard uptake value thresholds as well as using respiratory gated PET and CT planning for improved target delineation of moving targets. In addition, PET/CT based follow-up after radiation therapy has provided the possibility of early detection of local as well as distant recurrences after treatment. More research is needed to incorporate other biomarkers such as proliferative and hypoxia biomarkers in PET as well as integrating metabolic information in adaptive, patient-centered, tailored radiation therapy.

    Arany, P R

    2016-08-01

    The fundamental pathophysiologic response for the survival of all organisms is the process of wound healing. Inadequate or lack of healing constitutes the etiopathologic basis of many oral and systemic diseases. Among the numerous efforts to promote wound healing, biophotonics therapies have shown much promise. Advances in photonic technologies and a better understanding of light-tissue interactions, from parallel biophotonics fields such as in vivo optical imaging and optogenetics, are spearheading their popularity in biology and medicine. Use of high-dose lasers and light devices in dermatology, ophthalmology, oncology, and dentistry are now popular for specific clinical applications, such as surgery, skin rejuvenation, ocular and soft tissue recontouring, and antitumor and antimicrobial photodynamic therapy. However, a less well-known clinical application is the therapeutic use of low-dose biophotonics termed photobiomodulation (PBM) therapy, which is aimed at alleviating pain and inflammation, modulating immune responses, and promoting wound healing and tissue regeneration. Despite significant volumes of scientific literature from clinical and laboratory studies noting the phenomenological evidence for this innovative therapy, limited mechanistic insights have prevented rigorous and reproducible PBM clinical protocols. This article briefly reviews current evidence and focuses on gaps in knowledge to identify potential paths forward for clinical translation with PBM therapy with an emphasis on craniofacial wound healing. PBM offers a novel opportunity to examine fundamental nonvisual photobiological processes as well as develop innovative clinical therapies, thereby presenting an opportunity for a paradigm shift from conventional restorative/prosthetic approaches to regenerative modalities in clinical dentistry.

    Diabetes mellitus is a major health problem in developing countries. There are various insulin therapies to manage diabetes mellitus. This systematic review evaluates various insulin therapies for management of diabetes mellitus worldwide. This review also focuses on recent developments being explored for better management of diabetes mellitus. We reviewed a number of published articles from 2002 to 2016 to find out the appropriate management of diabetes mellitus. The paramount parameters of the selected studies include the insulin type & its dose, type of diabetes, duration and comparison of different insulin protocols. In addition, various newly developed approaches for insulin delivery with potential output have also been evaluated. A great variability was observed in managing diabetes mellitus through insulin therapy and the important controlling factors found for this therapy include; dose titration, duration of insulin use, type of insulin used and combination therapy of different insulin. A range of research articles on current trends and recent advances in insulin has been summarized, which led us to the conclusion that multiple daily insulin injections or continuous subcutaneous insulin infusion (insulin pump) is the best method to manage diabetes mellitus. In future perspectives, development of the oral and inhalant insulin would be a tremendous breakthrough in Insulin therapy. Copyright © 2017 Diabetes India. Published by Elsevier Ltd.

    Farrell, Nicholas R; Kemp, Joshua J; Blakey, Shannon M; Meyer, Johanna M; Deacon, Brett J

    2016-10-01

    Owing to concerns about the safety and tolerability of exposure therapy, many clinicians deliver the treatment in an overly cautious manner, which may limit its effectiveness. Although didactic training in exposure reduces clinician concerns about the treatment to a moderate extent, improved training strategies are needed to minimize these concerns and improve exposure delivery. The present study compared the effectiveness of a standard (i.e., didactic) exposure therapy training model to an "enhanced" training paradigm encompassing strategies derived from social-cognitive theory on attitude change. Clinicians (N = 49) were assigned to one of the two training approaches. Relative to standard training, clinicians who received enhanced training showed: (a) significantly greater reductions in concerns about exposure from pre- to post-training, and (b) superior self-reported delivery of the treatment. Reduction in concerns during training mediated the effects of training condition on clinicians' self-reported exposure delivery. These findings underscore the importance of addressing clinician concerns about exposure therapy in training contexts. Copyright © 2016 Elsevier Ltd. All rights reserved.

  20. Current and Emerging Therapies for the Treatment of Cystic Fibrosis or Mitigation of Its Symptoms.

    2016-03-01

    Clinical presentation of the chronic, heritable condition cystic fibrosis (CF) is complex, with a diverse range of symptoms often affecting multiple organs with varying severity. The primary source of morbidity and mortality is due to progressive destruction of the airways attributable to chronic inflammation arising from microbial colonisation. Antimicrobial therapy combined with practises to remove obstructive mucopurulent deposits form the cornerstone of current therapy. However, new treatment options are emerging which offer, for the first time, the opportunity to effect remission from the underlying cause of CF. Here, we discuss these therapies, their mechanisms of action, and their successes and failures in order to illustrate the shift in the nature of how CF will likely be managed into the future.

  1. Current view of the immunopathogenesis in inflammatory bowel disease and its implications for therapy

    Institute of Scientific and Technical Information of China (English)

    MI Torres; A Rios

    2008-01-01

    Although the aetiology of inflammatory bowel disease (IBD) remains unknown, the pathogenesis is gradually being unravelled, seeming to be the result of a combination of environmental, genetic, and immunological factors in which an uncontrolled immune response within the intestinal lumen leads to inflammation in genetically predisposed individuals. Multifactorial evidence suggests that a defect of innate immune response to microbial agents is involved in IBD. This editorial outlines the immunopathogenesis of IBD and their current and future therapy. We present IBD as a result of dysregulated mucosal response in the intestinal wall facilitated by defects in epithelial barrier function and the mucosal immune system with excessive production of cytokines growth factors, adhesion molecules, and reactive oxygen metabolites, resulting in tissue injury. Established and evolving therapies are discussed in the second part of this editorial and at the end of this section we review new therapies to modulate the immune system in patients with IBD.

    Hepatocellular carcinoma is the most common primary liver cancer and it represents the majority of cancer-related deaths in the world. More than 70% of patients present at an advanced stage, beyond potentially curative options. Ytrrium-90 selective internal radiation therapy (Y90-SIRT) with glass microspheres is rapidly gaining acceptance as a potential therapy for intermediate and advanced stage primary hepatocellular carcinoma and liver metastases. The technique involves delivery of Y90 infused glass microspheres via the hepatic arterial blood flow to the appropriate tumor. The liver tumor receives a highly concentrated radiation dose while sparing the healthy liver parenchyma due to its preferential blood supply from portal venous blood. There are two commercially available devices: TheraSphere® and SIR-Spheres®. Although, Y90-SIRT with glass microspheres improves median survival in patients with intermediate and advanced hepatocellular carcinoma and has the potential to downstage hepatocellular carcinoma so that the selected candidates meet the transplantable criteria, it has not gained widespread acceptance due to the lack of large randomized controlled trials. Currently, there are various clinical trials investigating the use of Y90-SIRT with glass microspheres for treatment of hepatocellular carcinoma and the outcomes of these trials may result in the incorporation of Y90-SIRT with glass microspheres into the treatment guidelines as a standard therapy option for patients with intermediate and advanced stage hepatocellular carcinoma.

    2014-06-01

    Intravenous immunoglobulin therapy is of proven effect in chronic inflammatory neuropathies, including chronic inflammatory demyelinating polyneuropathy (CIDP) and multifocal motor neuropathy (MMN). In more recent years, there have been a number of anecdotal case reports and small series, followed by a few trials of variable design, of subcutaneous immunoglobulin therapy in these neuropathies. To date, limited evidence suggests that the subcutaneous route may be a more clinically effective, better-tolerated, at least cost-equivalent and a more patient-friendly option than the still more used intravenous alternative. Long-term efficacy is not as yet established in neuropathic indications by randomised controlled clinical trial evidence, and it is likely that the subcutaneous route may not be suitable in all cases with some hints to this effect appearing from the limited data available to date. Further studies are ongoing, including those of dose comparison, and more are likely to be planned in future. The literature on the use of subcutaneous immunoglobulin therapy in chronic inflammatory neuropathy is reviewed here. The current use in clinical practice, day-to-day benefits, including quality of life measures and health economics as published thus far, are evaluated. The limitations of this form of treatment in CIDP and MMN are also analysed in the light of current literature and taking into account the remaining unknowns. Future prospects and research with this mode of immunoglobulin therapy administration are discussed.

    2013-09-01

    Age-related macular degeneration (ARMD) is the leading cause of irreversible blindness in developed countries. There are currently no cures, but there are promising potential therapies that target the underlying disease mechanisms of dry ARMD. Stem cells, ciliary neurotrophic factor, rheopheresis, ozonated autohemotherapy and prostaglandins show promise in stabilizing or improving visual acuity. Age-Related Eye Disease Study vitamins may reduce progression to severe ARMD. Adjuvant therapy like low vision rehabilitation and implantable miniature telescopes may help patients adjust to the sequelae of their disease, and herbal supplementation with saffron, zinc monocysteine and phototrop may be helpful. Therapies that are currently in clinical trials include brimonidine, doxycycline, anti-amyloid antibodies (GSK933776 and RN6G), RPE65 inhibitor (ACU-4429), complement inhibitors (ARC1905, FCFD4514S), hydroxychloroquine, intravitreal fluocinolone acetate and vasodilators like sildenafil, moxaverine and MC-1101. Therapies that have not been shown to be effective include POT-4, eculizumab, tandospirone, anecortave acetate, the antioxidant OT-551, sirolimus and vitamin E.

    2003-06-01

    The purpose of this lecture is to review the development of current neurophysiology and the revised standard of society for clinical EEG. 1. The improvement of neurophysiological tests. 1) EEG and evoked potential: EEG and evoked potential testing includes the routine EEG recording, EEG monitoring in surgical operation, all night sleep polygraph for the diagnosis of sleep apnea syndrome and many kinds of brain evoked potentials. Especially, the P300 component in the ERP(event-related evoked potential) is useful for the testing of essential brain functions. 2) EMG and evoked EMG: These tests are applied for the diagnosis of neurogenic, myogenic and neuromuscular junction disorder, and also the single fiber EMG using micro needle electrode is useful for the diagnosis of myasthenia gravis. Motor and sensory nerve conduction velocity are calculated from the latency of evoked EMGs. Furthermore, the distribution of these conduction velocities in many nerve fibers is measured by the collision technique. 3) Other tests: Near-infrared spectroscopy for the testing of brain functions has made rapid progress, and the transcranial magnetic stimulation method has come to be used for evaluation of functional diseases in the pyramidal tract, cerebellum and the spinal cord. 2. The revised JSCN technical standards for clinical EEG. The revised recording conditions of ECI(electro cerebral inactivity: flat EEG) in brain death are the focus of this lecture.

    2014-03-01

    Several studies have demonstrated the importance of environmental conditions in the radiology reporting environment, with many indicating that incorrect parameters could lead to error and misinterpretation. Literature is available with recommendations as to the levels that should be achieved in clinical practice, but evidence of adherence to these guidelines in radiology reporting environments is absent. This study audited the reporting environments of four teleradiologist and eight hospital based radiology reporting areas. This audit aimed to quantify adherence to guidelines and identify differences in the locations with respect to layout and design, monitor distance and angle as well as the ambient factors of the reporting environments. In line with international recommendations, an audit tool was designed to enquire in relation to the layout and design of reporting environments, monitor angle and distances used by radiologists when reporting, as well as the ambient factors such as noise, light and temperature. The review of conditions were carried out by the same independent auditor for consistency. The results obtained were compared against international standards and current research. Each radiology environment was given an overall compliance score to establish whether or not their environments were in line with recommended guidelines. Poor compliance to international recommendations and standards among radiology reporting environments was identified. Teleradiology reporting environments demonstrated greater compliance than hospital environments. The findings of this study identified a need for greater awareness of environmental and perceptual issues in the clinical setting. Further work involving a larger number of clinical centres is recommended.

    The 2014 Ebola outbreak, the largest recorded, took us largely unprepared, with no available vaccine or specific treatment. In this context, the World Health Organization declared that the humanitarian use of experimental therapies against Ebola Virus (EBOV) is ethical. In particular, an experimental treatment consisting of a cocktail of three monoclonal antibodies (mAbs) produced in tobacco plants and specifically directed to the EBOV glycoprotein (GP) was tested in humans, apparently with good results. Several mAbs with high affinity to the GP have been described. This review discusses our current knowledge on this topic. Particular emphasis is devoted to those mAbs that have been assayed in animal models or humans as possible therapies against Ebola. Engineering aspects and challenges for the production of anti-Ebola mAbs are also briefly discussed; current platforms for the design and production of full-length mAbs are cumbersome and costly.

    2015-11-07

    Hepatic encephalopathy (HE) is a severe neuropsychiatric syndrome that most commonly occurs in decompensated liver cirrhosis and incorporates a spectrum of manifestations that ranges from mild cognitive impairment to coma. Although the etiology of HE is not completely understood, it is believed that multiple underlying mechanisms are involved in the pathogenesis of HE, and one of the main factors is thought to be ammonia; however, the ammonia hypothesis in the pathogenesis of HE is incomplete. Recently, it has been increasingly demonstrated that inflammation, including systemic inflammation, neuroinflammation and endotoxemia, acts in concert with ammonia in the pathogenesis of HE in cirrhotic patients. Meanwhile, a good number of studies have found that current therapies for HE, such as lactulose, rifaximin, probiotics and the molecular adsorbent recirculating system, could inhibit different types of inflammation, thereby improving the neuropsychiatric manifestations and preventing the progression of HE in cirrhotic patients. The anti-inflammatory effects of these current therapies provide a novel therapeutic approach for cirrhotic patients with HE. The purpose of this review is to describe the inflammatory mechanisms behind the etiology of HE in cirrhosis and discuss the current therapies that target the inflammatory pathogenesis of HE.

    By minimising the effect of irradiation on surrounding tissue, intensity-modulated radiation therapy (IMRT) can deliver higher, more effective doses to the targeted tumour site, minimising treatment-related morbidity and possibly improving cancer control and cure. A multidisciplinary IMRT Expert Panel was convened to develop the organisational standards for the delivery of IMRT. The systematic literature search used MEDLINE, EMBASE, the Cochrane Database, the National Guidelines Clearing House and the Health Technology Assessment Database. An environmental scan of unpublished literature used the Google search engine to review the websites of key organisations, cancer agencies/centres and vendor sites in Canada, the USA, Australia and Europe. In total, 22 relevant guidance documents were identified; 12 from the published literature and 10 from the environmental scan. Professional and organisational standards for the provision of IMRT were developed through the analysis of this evidence and the consensus opinion of the IMRT Expert Panel. The resulting standards address the following domains: planning of new IMRT programmes, practice setting requirements, tools, devices and equipment requirements; professional training requirements; role of personnel; and requirements for quality assurance and safety. Here the IMRT Expert Panel offers organisational and professional standards for the delivery of IMRT, with the intent of promoting innovation, improving access and enhancing patient care.

  14. Molecular Targeted Therapies for the Treatment of Leptomeningeal Carcinomatosis: Current Evidence and Future Directions.

    2016-07-05

    Leptomeningeal carcinomatosis (LMC) is the multifocal seeding of cerebrospinal fluid and leptomeninges by malignant cells. The incidence of LMC is approximately 5% in patients with malignant tumors overall and the rate is increasing due to increasing survival time of cancer patients. Eradication of the disease is not yet possible, so the treatment goals of LMC are to improve neurologic symptoms and to prolong survival. A standard treatment for LMC has not been established due to low incidences of LMC, the rapidly progressing nature of the disease, heterogeneous populations with LMC, and a lack of randomized clinical trial results. Treatment options for LMC include intrathecal chemotherapy, systemic chemotherapy, and radiation therapy, but the prognoses remain poor with a median survival of <3 months. Recently, molecular targeted agents have been applied in the clinic and have shown groundbreaking results in specific patient groups epidermal growth factor receptor (EGFR)-targeted therapy or an anaplastic lymphoma kinase (ALK) inhibitor in lung cancer, human epidermal growth factor receptor 2 (HER2)-directed therapy in breast cancer, and CD20-targeted therapy in B cell lymphoma).

    Full Text Available Leptomeningeal carcinomatosis (LMC is the multifocal seeding of cerebrospinal fluid and leptomeninges by malignant cells. The incidence of LMC is approximately 5% in patients with malignant tumors overall and the rate is increasing due to increasing survival time of cancer patients. Eradication of the disease is not yet possible, so the treatment goals of LMC are to improve neurologic symptoms and to prolong survival. A standard treatment for LMC has not been established due to low incidences of LMC, the rapidly progressing nature of the disease, heterogeneous populations with LMC, and a lack of randomized clinical trial results. Treatment options for LMC include intrathecal chemotherapy, systemic chemotherapy, and radiation therapy, but the prognoses remain poor with a median survival of <3 months. Recently, molecular targeted agents have been applied in the clinic and have shown groundbreaking results in specific patient groups epidermal growth factor receptor (EGFR-targeted therapy or an anaplastic lymphoma kinase (ALK inhibitor in lung cancer, human epidermal growth factor receptor 2 (HER2-directed therapy in breast cancer, and CD20-targeted therapy in B cell lymphoma. Moreover, there are results indicating that the use of these agents under proper dose and administration routes can be effective for managing LMC. In this article, we review molecular targeted agents for managing LMC.

    Anaemia is one of the most common risk factors in the area of obstetrics and perinatal medicine. During pregnancy and in the puerperium it is associated with an increased incidence of both maternal and fetal morbidity and mortality, the extent of which is dependent upon the severity of anaemia and the resulting complications. In order to correctly diagnose the type and degree of anaemia, a prerequisite for selection of the proper therapy, one must first of all correctly differentiate between the relative, i.e., the physiological anaemia of pregnancy due to the normal plasma volume increase during pregnancy, and "real anaemias" with various different pathophysiological causes. When defining the Hb cutoff value for anaemia in pregnancy, the extent of the plasma volume changes with respect to the gestational age must be taken into consideration. It has been found that haemoglobin values < 11.0 g/dl in the first and third trimesters, and < 10.5 g/dl in the second trimester may point to an anaemic situation which should be further clarified. The first important steps for diagnosing anaemia in a pregnant patient include a thorough check of her medical history and a medical examination. This procedure often lays the basis for a correct diagnosis. The current gold standard to detect iron deficiency remains the serum ferritin value. To be reliable, this requires the ruling out of an infection (chronic or acute) as a cause of the anaemia. We recommend a complete laboratory test for the exact haematological status as well as the assessment of specific chemical laboratory parameters. These should include a palette of additional, promising new parameters such as hypochromic red cells and transferrin receptors which allow more accurate detection of iron deficiency and differential diagnosis of iron deficiency anaemia. After correct diagnosis, major emphasis should be put on safe and effective treatment of anaemia which again depends on severity of anaemia, time for restoration

    Postmenopausal osteoporosis is an asymptomatic skeletal disease that is often underdiagnosed and undertreated. Osteoporotic fractures are associated with substantial morbidity and mortality and impaired quality of life-socially, emotionally, and financially. Considering the growing burden of osteoporotic fractures worldwide, there remains an ongoing need for progress in the diagnosis of osteoporosis, identification of individuals at high fracture risk, and treatment to prevent fractures. Adequate intake of calcium and vitamin D is recommended as baseline therapy for osteoporosis prevention and treatment. Available pharmacological agents for the management of postmenopausal osteoporosis may not be appropriate for all women. Oral bisphosphonates are generally considered first-line therapy for patients with osteoporosis, but their use may be limited by gastrointestinal side effects. Other agents include hormone therapy, the selective estrogen receptor modulator (SERM) raloxifene, salmon calcitonin, teriparatide (human recombinant parathyroid hormone), and strontium ranelate (in some countries). Factors that may contribute to poor compliance and persistence with current osteoporosis therapies include drug intolerance, complexity of dosing regimens, and poor understanding of the relative benefit and risk with treatment. Emerging therapies for postmenopausal osteoporosis include novel SERMs (bazedoxifene, lasofoxifene, ospemifene, arzoxifene) and denosumab. Because SERMs can display mixed functional estrogen receptor agonist or antagonist activity depending on the target tissue, they may confer beneficial effects on bone with limited stimulation of other tissues (e.g., breast, endometrium). Clinical investigation of these promising new agents is ongoing to evaluate efficacy and safety, with the goal of developing effective strategies to maximize long-term tolerance, compliance, and persistence with therapy.

    2017-07-01

    Continuous renal replacement therapy (CRRT) use continues to expand globally. Despite improving technology, CRRT remains a complex intervention. Delivery of high-quality CRRT requires close collaboration of a multidisciplinary team including members of the critical care medicine, nephrology, nursing, pharmacy, and nutrition support teams. While significant gaps in medical evidence regarding CRRT persist, the growing evidence base supports evolving best practice and consensus to define high-quality CRRT. Unfortunately, there is wide variability in CRRT operating characteristics and limited uptake of these best practices. This article will briefly review the current best practice on important aspects of CRRT delivery including CRRT dose, anticoagulation, dialysis vascular access, fluid management, and drug dosing in CRRT.

    Full Text Available Abstract Background Intensity-modulated radiation therapy (IMRT affords unparalleled capacity to deliver conformal radiation doses to tumors in the central nervous system. However, to date, there are few reported outcomes from using IMRT, either alone or as a boost technique, for standard fractionation radiotherapy for glioblastoma multiforme (GBM. Methods Forty-two patients were treated with IMRT alone (72% or as a boost (28% after 3-dimensional conformal radiation therapy (3D-CRT. Thirty-three patients with primary disease and 9 patients with recurrent tumors were included. Thirty-four patients (81% had surgery, with gross tumor resection in 13 patients (36%; 22 patients (53% received chemo-radiotherapy. The median total radiation dose for all patients was 60 Gy with a range from 30.6 to 74 Gy. Standard fractions of 1.8 Gy/day to 2.0 Gy/day were utilized. Results Median survival was 8.7 months, with 37 patients (88% deceased at last contact. Nonparametric analysis showed no survival difference in IMRT-boost vs. IMRT-only groups. Conclusion While technically feasible, preliminary results suggest delivering standard radiation doses by IMRT did not improve survival outcomes in this series compared to historical controls. In light of this lack of a survival benefit and the costs associated with use of IMRT, future prospective trials are needed to evaluate non-survival endpoints such as quality of life and functional preservation. Short of such evidence, the use of IMRT for treatment of GBM needs to be carefully rationalized.

    The recent literature has shown that triple antiplatelet therapy with cilostazol in addition to the standard dual antiplatelet therapy with aspirin and clopidogrel may reduce platelet reactivity and improve clinical outcomes following percutaneous coronary intervention. The purpose of this meta-analysis is to compare the efficacy of triple antiplatelet therapy and dual antiplatelet therapy in regard to on-treatment platelet reactivity. Nine studies (n = 2179) comparing on-treatment platelet reactivity between dual antiplatelet therapy (n = 1193) and triple antiplatelet therapy (n = 986) in patients undergoing percutaneous coronary intervention were included. Primary end points were P2Y12 reaction unit (PRU) and platelet reactivity index (PRI). Secondary end points were platelet aggregation with adenosine diphosphate (ADP) 5 and 20 µmol/L and P2Y12% inhibition. Mean difference (MD) and 95% confidence intervals (CI) were computed and 2-sided α error antiplatelet therapy, triple antiplatelet therapy had significantly lower maximum platelet aggregation with ADP 5 µmol/L (MD: -14.4, CI: -21.6 to -7.2, P antiplatelet therapy significantly lowers platelet reactivity and may explain a decrease in thromboembolic events following coronary intervention; however, additional studies evaluating clinical outcomes will be helpful to determine the benefit of triple antiplatelet therapy.

    Several Phase I/II clinical trials aiming at the correction of X-linked CGD by gene transfer into hematopoietic stem cells (HSCs) have demonstrated the therapeutic potential of gene modified autologous HSCs for the treatment of CGD. Resolution of therapy-resistant bacterial and fungal infections in liver, lung and spinal canal of CGD patients were clearly documented in all trials. However, clinical benefits were not sustained over time due to the failure of gene transduced cells to engraft long-term. Moreover, severe adverse effects were observed in some of the treated patients due to insertional mutagenesis leading to the activation of growth promoting genes and to myeloid malignancy. These setbacks fostered the development of novel safety and efficacy improved vectors that have already entered or are about to enter the clinics. Meanwhile, ongoing research is constantly refining the CGD disease phenotype, including the definition of factors that may explain the unique engraftment phenotype observed in CGD gene therapy trials. This review provides a condensed overview on the current knowledge of the molecular pathomechanisms and clinical manifestations of CGD and summarizes the lessons learned from clinical gene therapy trials, the preclinical progress in vector design and the future perspectives for the gene therapy of CGD.

    Photodynamic therapy (PDT) is a clinically approved cancer therapy, based on a photochemical reaction between a light activatable molecule or photosensitizer, light, and molecular oxygen. When these three harmless components are present together, reactive oxygen species are formed. These can directly damage cells and/or vasculature, and induce inflammatory and immune responses. PDT is a two-stage procedure, which starts with photosensitizer administration followed by a locally directed light exposure, with the aim of confined tumor destruction. Since its regulatory approval, over 30 years ago, PDT has been the subject of numerous studies and has proven to be an effective form of cancer therapy. This review provides an overview of the clinical trials conducted over the last 10 years, illustrating how PDT is applied in the clinic today. Furthermore, examples from ongoing clinical trials and the most recent preclinical studies are presented, to show the directions, in which PDT is headed, in the near and distant future. Despite the clinical success reported, PDT is still currently underutilized in the clinic. We also discuss the factors that hamper the exploration of this effective therapy and what should be changed to render it a more effective and more widely available option for patients.

    Subcutaneous or intravenous immunoglobulin replacement is the mainstay of treatment for most patients with primary immunodeficiency disease (PID). The purpose of this study was to gain an understanding of how existing PID therapies affect patient lives and to identify desired improvements to immunoglobulin treatments. An online questionnaire was made available through the International Patient Organisation for Primary Immunodeficiencies to patients with PID and their caregivers regarding current treatment satisfaction, living with PID, and patient preferences using a conjoint approach. Health-related quality of life was canvassed via questionnaires using the Short Form 12 Health Survey and EuroQoL 5 Dimensions. A total of 300 responded to the survey (72% patients with PID and 28% caregivers) from across 21 countries, mostly the UK, Sweden, Canada, France, Germany, and Spain. Fifty-three percent and 45% of patients received intravenous and subcutaneous therapy, respectively. Most respondents (76%) were satisfied with their current treatment, reflecting the benefits that immunoglobulin therapy provides for patient health and well-being. However, patients remained below the physical and mental well-being norms for health-related quality of life as determined by the questionnaire. All respondents expressed a desire for 4-weekly infusions, the ability to administer these at home, self-administration, shorter duration of administration, and fewer needle sticks. The results of this survey highlight the importance of providing access to different treatment options and modes of administration to ensure individual patient needs are best met.

    Full Text Available The volumetric intensity modulated arc therapy (VMAT is a novel radiation technique that delivers a highly conformal radiation dose to the target by allowing the simultaneous variation of gantry rotation speed, dose rate and multiple-leaf collimators leaf positions. The aim of this study was to review the current literature on two VMAT systems, RapidArc and SmartArc with main focus on planning studies of lung cancer. A systematic review of available data was conducted using MEDLINE/PubMed with the keywords ′′lung′′ and "VMAT". The published data show that VMAT techniques have clear superiority over three-dimensional conformal radiation therapy with regard to improving dose conformity and sparing of organs at risks (OARs. The data indicates that for lung tumor VMAT and intensity modulated radiation therapy (IMRT provide equivalent dose homogeneity, dose conformity and target volume coverage; however, contradictory results were obtained in terms of OARs sparing. The major advantages of VMAT over IMRT are the reduction in the number of monitor units and faster treatment delivery times without compromising the quality of the treatment plans. Moreover, faster delivery time is more patient-friendly and it minimizes intra-fractional patient motion allowing treatment volumes stay within their respective treatment margins. Current literature data shows that VMAT can be a good option to treat lung cancer; however, data on clinical trials are still lacking. The clinical trials are essential to confirm the safety and efficacy of VMAT techniques.

    Systemic sclerosis (SSc) is a chronic autoimmune disease with a high morbidity and mortality. Skin and organ fibrosis are key manifestations of SSc, for which no generally accepted therapy is available. Thus, there is a high unmet need for novel anti-fibrotic therapeutic strategies in SSc. At the same time, important progress has been made in the identification and characterization of potential molecular targets in fibrotic diseases over the recent years. In this review, we have selected four targeted therapies, which are tested in clinical trials in SSc, for in depths discussion of their preclinical characterization. Soluble guanylate cyclase (sGC) stimulators such as riociguat might target both vascular remodeling and tissue fibrosis. Blockade of interleukin-6 might be particularly promising for early inflammatory stages of SSc. Inhibition of serotonin receptor 2b signaling links platelet activation to tissue fibrosis. Targeting simultaneously multiple key molecules with the multityrosine kinase-inhibitor nintedanib might be a promising approach in complex fibrotic diseases such as SSc, in which many partially independent pathways are activated. Herein, we also give a state of the art overview of the current classification, clinical presentation, diagnostic approach, and treatment options of localized scleroderma. Finally, we discuss whether the novel targeted therapies currently tested in SSc could be used for localized scleroderma.

    Phytocompounds have been used in cosmeceuticals for decades and have shown potential for beauty applications, including sunscreen, moisturizing and antiaging, and skin-based therapy. The major concerns in the usage of phyto-based cosmeceuticals are lower penetration and high compound instability of various cosmetic products for sustained and enhanced compound delivery to the beauty-based skin therapy. To overcome these disadvantages, nanosized delivery technologies are currently in use for sustained and enhanced delivery of phyto-derived bioactive compounds in cosmeceutical sectors and products. Nanosizing of phytocompounds enhances the aseptic feel in various cosmeceutical products with sustained delivery and enhanced skin protecting activities. Solid lipid nanoparticles, transfersomes, ethosomes, nanostructured lipid carriers, fullerenes, and carbon nanotubes are some of the emerging nanotechnologies currently in use for their enhanced delivery of phytocompounds in skin care. Aloe vera, curcumin, resveratrol, quercetin, vitamins C and E, genistein, and green tea catechins were successfully nanosized using various delivery technologies and incorporated in various gels, lotions, and creams for skin, lip, and hair care for their sustained effects. However, certain delivery agents such as carbon nanotubes need to be studied for their roles in toxicity. This review broadly focuses on the usage of phytocompounds in various cosmeceutical products, nanodelivery technologies used in the delivery of phytocompounds to various cosmeceuticals, and various nanosized phytocompounds used in the development of novel nanocosmeceuticals to enhance skin-based therapy.

    Most people on folic acid to boost erythropoiesis and prophylactic antimicrobials, the standard management of steady state sickle cell disease (SCD), have unacceptable numbers of crises. The objective of this study was to evaluate the effects of adding multimodal therapy with potassium thiocyanate and omega-3 fatty acids to the standard management of steady state SCD. Pre- and post-treatment numbers of crises and other disease indices were compared in 16 HbSS individuals on folic acid and paludrine after 12 months of adding eicosapentaenoic acid 15 mg/kg/day, docosahexaenoic acid 10 mg/kg/day, and potassium thiocyanate 1-2 mL/day, each milliliter of which contained 250 mg of thiocyanate and 100 micrograms of iodine to prevent hypothyroidism: a possible side-effect due to competitive inhibition of the transport of iodide into the thyroid gland by thiocyanate. Median number of crises reduced from 3/yr to 1/yr (P < 0.0001). There was no evidence of impaired thyroid function. Plasma level of tri-iodothyronine improved (P < 0.0001). Steady state full blood count and bilirubin level did not change significantly. The findings suggest that addition of potassium thiocyanate and eicosapentaenoic and docosahexaenoic acids to standard management of steady state SCD reduces the number of crises. This observation needs to be evaluated in larger studies.

  10. The dark matter crisis: falsification of the current standard model of cosmology

    2012-01-01

    The current standard model of cosmology (SMoC) requires The Dual Dwarf Galaxy Theorem to be true. According to this theorem two types of dwarf galaxies must exist: primordial dark-matter (DM) dominated (type A) dwarf galaxies, and tidal-dwarf and ram-pressure-dwarf (type B) galaxies void of DM. In the model, type A dwarfs are distributed approximately spherically following the shape of the host galaxy DM halo, while type B dwarfs are typically correlated in phase-space. Type B dwarfs must exist in any cosmological theory in which galaxies interact. Only one type of dwarf galaxy is observed to exist on the baryonic Tully-Fisher plot and in the radius-mass plane. The Milky Way satellite system forms a vast phase-space-correlated structure that includes globular clusters and stellar and gaseous streams. Similar arguments apply to Andromeda. Other galaxies also have phase-space correlated satellite systems. Therefore, The Dual Galaxy Theorem is falsified by observation and dynamically relevant cold or warm DM on ...

The purpose of this study was to compare the taper variation in root canal preparations among Twisted Files and PathFiles-ProTaper .08 tapered rotary files to current standards. Methods. 60 root canals with severe angle of curvature (between 25∘ and 35∘ and short radius (<10 mm were selected. The canals were divided randomly into two groups of 30 each. After preparation with Twisted Files and PathFiles-ProTaper to size 25 taper .08, the diameter was measured using computed tomography (CT at 1, 3, and 16 mm. Canal taper preparation was calculated at the apical third and at the middle-cervical third. Results. Of the 2 file systems, both fell within the ±.05 taper variability. All preparations demonstrated variability when compared to the nominal taper .08. In the apical third, mean taper was significantly different between TF and PathFiles-ProTaper ( value < 0.0001; independent -test. Mean Taper was significantly higher with PathFile-ProTaper. In the middle-cervical third, mean Taper was significantly higher with TF ( value = 0.015; independent -test. Conclusion. Taper preparations of the investigated size 25 taper .08 were favorable but different from the nominal taper.

    2016-10-01

    Lung tumor response to therapy may be evaluated in most instances by morphological criteria such as RECIST 1.1 on computed tomography (CT) or magnetic resonance imaging (MRI). However, those criteria are limited because they are based on tumoral dimensional changes and do not take into account other morphologic criteria such as density evaluation, functional or metabolic changes that may occur following conventional or targeted chemotherapy. New techniques such as dual-energy CT, PET-CT, MRI including diffusion-weighted MRI has to be considered into the new technical armamentarium for tumor response evaluation. Integration of all informations provided by the different imaging modalities has to be integrated and represents probably the future goal of tumor response evaluation. The aim of the present paper is to review the current and emerging imaging criteria used to evaluate the response of therapy in the field of lung cancer.

    2011-08-15

    There is a strong rationale for potential benefits from proton therapy (PT) for selected cancers of the head and neck because of the opportunity to improve the therapeutic ratio by improving radiation dose distributions and because of the significant differences in radiation dose distribution achievable with x-ray-based radiation therapy (RT) and PT. Comparisons of dose distributions between x-ray-based and PT plans in selected cases show specific benefits in dose distribution likely to translate into improved clinical outcomes. However, the use of PT in head and neck cancers requires special considerations in the simulation and treatment planning process, and currently available PT technology may not permit realization of the maximum potential benefits of PT. To date, few clinical data are available, but early clinical experiences in sinonasal tumors in particular suggest significant improvements in both disease control and radiation-related toxicity

    Multiple sclerosis (MS) is a chronic inflammatory demyelinating central nervous system disease that typically strikes young adults, especially women. The pathobiology of MS includes inflammatory and neurodegenerative mechanisms that affect both white and gray matter. These mechanisms underlie the relapsing, and often eventually progressive, course of MS, which is heterogeneous; confident prediction of long-term individual prognosis is not yet possible. However, because revised MS diagnostic criteria that incorporate neuroimaging data facilitate early diagnosis, most patients are faced with making important long-term treatment decisions, most notably the use and selection of disease-modifying therapy (DMT). Currently, there are 10 approved MS DMTs with varying degrees of efficacy for reducing relapse risk and preserving neurological function, but their long-term benefits remain unclear. Moreover, available DMTs differ with respect to the route and frequency of administration, tolerability and likelihood of treatment adherence, common adverse effects, risk of major toxicity, and pregnancy-related risks. Thorough understanding of the benefit-risk profiles of these therapies is necessary to establish logical and safe treatment plans for individuals with MS. We review the available evidence supporting risk-benefit profiles for available and emerging DMTs. We also assess the place of individual DMTs within the context of several different MS management strategies, including those currently in use (sequential monotherapy, escalation therapy, and induction and maintenance therapy) and others that may soon become feasible (combination approaches and "personalized medicine"). We conducted this review using a comprehensive search of MEDLINE, PubMed, EMBASE, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials, from January 1, 1990, to August 31, 2013. The following search terms were used: multiple sclerosis, randomized controlled trials

    2008-01-01

    Renal cell carcinoma (RCC) is regarded as one of the most refractory malignancies. A further study of the molecular mechanism of RCC formation has led to a series of successful examples for treatment of patients with advanced RCC. Over the past 20 years, a nonspecific immunotherapy, with cytokines, has been employed as the gold standard for therapy of metastatic RCC. However, with scientific development and clinical testing of new drugs, targeted molecular cancer therapy has become a focus of interest. At the same time, with a better understanding of RCC,the treatment method has converged on anti-vascular endothelial growth factor (VEGF) and related molecular-targeted pathways.A large amount of research and numerous clinical trials have demonstrated the clinical efficacy of the targeted molecular therapies in patients with metastatic RCC. For example sorafenib and sunitinib were approved, in 2005 and 2006 respectively, by the U.S. FDA for treating advanced RCC. In this report, issues such as the importance of VEGF in RCC and the studies of bevacizumab,sunitinib and sorafenib in treating metastatic RCC etc., are reviewed.

    Full Text Available Bishnu H Subedi,1,2 Parag H Joshi,1 Steven R Jones,1 Seth S Martin,1 Michael J Blaha,1 Erin D Michos1 1Johns Hopkins Ciccarone Center for the Prevention of Heart Disease, 2Greater Baltimore Medical Center, Baltimore, MD, USA Abstract: Many studies have suggested that a significant risk factor for atherosclerotic cardiovascular disease (ASCVD is low high-density lipoprotein cholesterol (HDL-C. Therefore, increasing HDL-C with therapeutic agents has been considered an attractive strategy. In the prestatin era, fibrates and niacin monotherapy, which cause modest increases in HDL-C, reduced ASCVD events. Since their introduction, statins have become the cornerstone of lipoprotein therapy, the benefits of which are primarily attributed to decrease in low-density lipoprotein cholesterol. Findings from several randomized trials involving niacin or cholesteryl ester transfer protein inhibitors have challenged the concept that a quantitative elevation of plasma HDL-C will uniformly translate into ASCVD benefits. Consequently, the HDL, or more correctly, HDL-C hypothesis has become more controversial. There are no clear guidelines thus far for targeting HDL-C or HDL due to lack of solid outcomes data for HDL specific therapies. HDL-C levels are only one marker of HDL out of its several structural or functional properties. Novel approaches are ongoing in developing and assessing agents that closely mimic the structure of natural HDL or replicate its various functions, for example, reverse cholesterol transport, vasodilation, anti-inflammation, or inhibition of platelet aggregation. Potential new approaches like HDL infusions, delipidated HDL, liver X receptor agonists, Apo A-I upregulators, Apo A mimetics, and gene therapy are in early phase trials. This review will outline current therapies and describe future directions for HDL therapeutics.

    Nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH) is considered to be a hepatic manifestation of metabolic syndrome, and its incidence is rapidly increasing worldwide. It is currently the most common chronic liver disease. NASH can progress to liver cirrhosis and hepatocellular carcinoma, and may result in liver-related death. Currently, the principal treatment for NAFLD/NASH is lifestyle modification by diet and exercise. However, pharmacological therapy is indispensable because obese patients with NAFLD often have difficulty maintaining improved lifestyles. The pathogenesis of NAFLD/NASH has not been completely elucidated. However, insulin resistance, inflammatory cytokines, and oxidative stress are thought to be important in the development and/or progression of the disease. Currently, insulin sensitizers (thiazolidinediones) and antioxidants (vitamin E) seem to be the most promising therapeutic agents for NAFLD/NASH, and lipid-lowering drugs, pentoxifylline, angiotensin receptor blockers, and n-3 polyunsaturated fatty acids also have promise. However, there is a lack of consensus regarding the most effective and appropriate pharmacotherapy for NAFLD/NASH. Animal experiments suggest that herbal medicines and natural products may be promising therapeutic agents for NAFLD/NASH, but their efficacy and safety are yet to be investigated in human studies. In this paper, we review the existing and potential pharmacological therapies for NAFLD/NASH.

    The aim of the study is to ascertain the most relevant aspects of the current management of renal replacement therapy (RRT) in critically ill patients, and to analyze renal function recovery and mortality in patients undergoing RRT. A non-interventional three-month observational study was made in 2012, with a follow-up period of 90 days, in 21 centers in Catalonia (Spain). Demographic information, severity scores and clinical data were obtained, as well as RRT parameters. patients aged ≥ 16 years admitted to Intensive Care Units (ICUs) and subjected to RRT. A total of 261 critically ill patients were recruited, of which 35% had renal dysfunction prior to admission. The main reason for starting RRT was oliguria; the most widely used RRT modality was hemodiafiltration; and the median prescribed dose at baseline was 35mL/kg/h. The median time of RRT onset from ICU admission was one day. The mortality rate at 30 and 90 days was 46% and 54%, respectively, and was associated to greater severity scores and a later onset of RRT. At discharge, 85% of the survivors had recovered renal function. Current practice in RRT in Catalonia abides with the current clinical practice guidelines. Mortality related to RRT is associated to later onset of such therapy. The renal function recovery rate at hospital discharge was 85% among the patients subjected to RRT.

    Standard triple therapy remains an important option for eradicating Helicobacter pylori (Hp) in developing countries because of its relatively low cost. However, salvage therapies after failure of this regimen remain undefined. The authors therefore investigate the efficacy of 1-week quadruple therapy as a second-line treatment of Hp infection after failure of standard triple therapy. Seventy-eight patients who failed Hp eradication using a 2-week bismuth-based triple therapy were enrolled and received a course of 1-week quadruple therapy (lansoprazole, 30 mg twice daily; bismuth subcitrate, 120 mg four times daily; clarithromycin, 500 mg twice daily; and amoxicillin, 1,000 mg twice daily) as a salvage regimen. The Hp status was reassessed 7 weeks after cessation of therapy. Among the 78 patients, Hp eradication was achieved in 65 (83%, 95% confidence interval = 75-91%) by intention-to-treat analysis. Only five (6%) patients had side effects, and all (100%) showed good drug compliance. Multivariate analysis disclosed that coffee drinking was an independent factor for treatment failure (odds ratio = 5.3, 95% confidence interval = 1.2-23.6, p = 0.028). The authors therefore conclude that their 1-week quadruple therapy is an effective salvage regimen for Hp infection after failure of standard triple therapy in the population examined. The benefits of this regimen include the high eradication rate, the short duration of treatment, fewer side effects, and good drug compliance. Coffee consumption possibly is an important factor in failure of the rescue regimen. The mechanisms underlying the association between coffee drinking and eradication failure require further research.

    In the West in particular, the vast majority of gastric cancer(GC) patients present with advanced-stage disease. Although combination chemotherapy is stillthe most important component of treatment for these patients, it confers a modest survival advantage. Recently, increased knowledge of the key molecular signaling pathways involved in gastric carcinogenesis has led to the discovery of specific molecular-targeted therapeutic agents. Some of these agents such as trastuzumab and ramucirumab have changed the treatment paradigm for this disease. In this paper, we will summarize the current clinical status of targeted drug therapy in the management of GC.

    Full Text Available Stress urinary incontinence (SUI is a common urinary system disease that mostly affects women. Current treatments still do not solve the critical problem of urethral sphincter dysfunction. In recent years, there have been major developments in techniques to obtain, culture, and characterize autologous stem cells as well as many studies describing their applications for the treatment of SUI. In this paper, we review recent publications and clinical trials investigating the applications of several stem cell types as potential treatments for SUI and the underlying challenges of such therapy.

    Objective To study the efficacy of the low standard oral anticoagulation therapy following St Jude Medical (SJM) valve implantation for Chinese patients.Methods Totally 805 patients with a mean age of 42.70±11.09 years, enrolled into this study. Among them, 230 underwent aortic valve replacements (AVR), 381 mitral valve replacements (MVR), 189 double valve replacements (DVR) and 5 tricuspid valve replacememts (TVR). All patients received postoperative oral anticoagulation therapy based on a low standard of international normalized ratio (INR, 2.0-2.5). Of the 805 patients, 710 were followed up for 0.25-13 years (a median, 4.15 years). Results Postoperatively, 17 adverse events occurred. Operative mortality was 2.11%. The most frequent cause of operative mortality was a low cardiac output. During follow-up, there were 47 anticoagulant-induced hemorrhages [1.59%/patient-year (pt-yr)], 10 cases of thromboembolism (0.34%/pt-yr), and 3 mechanical valve thromboses (0.19%/pt-yr). There were 44 late deaths and the linearized late mortality rates were 0.51%pt-yr. Estimates of actuarial survival for all patients at 5 and 10 years was 97.45% (0.70%) and 77.96% (17.44%), respectively.Conclusions A low target INR range of 2.0-2.5 is preferable for Chinese patients so as to reduce the severe bleeding complications in those with conventionally higher levels of INR. The long-term results were satisfactory in terms of the numbers of those who suffered thrombosis, embolism and bleeding.

    Gastric cancer and cancer of the gastro-oesophageal junction (GOJ) are the 4th most common cancer diagnoses worldwide with regional differences in incidence rates.The treatment of gastric and GOJ cancers is complex and requires multimodality treatment including chemotherapy treatment,surgery,and radiotherapy.During the past decade considerable improvements were achieved by advanced surgical techniques,tailored chemotherapies/radiotherapy and technical innovations in clinical diagnostics.In patients with advanced or metastatic gastric/GOJ cancer systemic chemotherapy with fluoropyrimidine/platinum-based regimens (+/-human epidermal growth factor receptor-2 antibody) is the mainstay of treatment.Despite these improvements,the clinical outcome for patients with advanced or metastatic disease is generally poor with 5-year survival rates ranging between 5%-15%.These poor survival rates may to some extent be related that standard therapies beyond first-line therapies have never been defined.Considering that this patient population is often not fit enough to receive further treatments there is an increasing body of evidence from phase-2 studies that in fact second-line therapies may have a positive impact in terms of overall survival.Moreover two recently published phase-3 studies support the use of second-line chemotherapy.A South Korean study compared either,irinotecan or docetaxel with best supportive care and a German study compared irinotecan with best supportive care-both studies met their primary endpoint overall survival.In this "Field of Vision" article,we review these recently published phase-3 studies and put them into the context of clinical prognostic factors helping to guide treatment decisions in patients who most likely benefit.

    We explored the current practice with respect to the neuropsychological assessment of surgical epilepsy patients in European epilepsy centers, with the aim of harmonizing and establishing common standards. Twenty-six epilepsy centers and members of "E-PILEPSY" (a European pilot network of reference centers in refractory epilepsy and epilepsy surgery), were asked to report the status of neuropsychological assessment in adults and children via two different surveys. There was a consensus among these centers regarding the role of neuropsychology in the presurgical workup. Strong agreement was found on indications (localization, epileptic dysfunctions, adverse drugs effects, and postoperative monitoring) and the domains to be evaluated (memory, attention, executive functions, language, visuospatial skills, intelligence, depression, anxiety, and quality of life). Although 186 different tests are in use throughout these European centers, a core group of tests reflecting a moderate level of agreement could be discerned. Variability exists with regard to indications, protocols, and paradigms for the assessment of hemispheric language dominance. For the tests in use, little published evidence of clinical validity in epilepsy was provided. Participants in the survey reported a need for improvement concerning the validity of the tests, tools for the assessment of everyday functioning and accelerated forgetting, national norms, and test co-normalization. Based on the present survey, we documented a consensus regarding the indications and principles of neuropsychological testing. Despite the variety of tests in use, the survey indicated that there may be a core set of tests chosen based on experience, as well as on published evidence. By combining these findings with the results of an ongoing systematic literature review, we aim for a battery that can be recommended for the use across epilepsy surgical centers in Europe.

    Hepatitis B virus (HBV) reactivation represents an emerging cause of liver disease in patients undergoing treatment with biologic agents. In particular, the risk of HBV reactivation is heightened by the use monoclonal antibodies, such as rituximab (anti-CD20) and alemtuzumab (anti-CD52) that cause profound and long-lasting immunosuppression. Emerging data indicate that HBV reactivation could also develop following the use of other biologic agents, such as tumor necrosis factor (TNF)-α inhibitors. When HBV reactivation is diagnosed, it is mandatory to suspend biologic treatment and start antiviral agents immediately. However, pre-emptive antiviral therapy prior to monoclonal antibody administration is crucial in preventing HBV reactivation and its clinical consequences. Several lines of evidence have shown that risk of HBV reactivation is greatly reduced by the identification of high-risk patients and the use of prophylactic antiviral therapy. In this article, we discuss current trends in the management of HBV reactivation in immunosuppressed patients receiving biologic therapy, such as rituximab, alemtuzumab and TNF-α antagonists.

    Full Text Available Research into the effects of animal-assisted interventions (AAIs has primarily addressed human health outcomes. In contrast, only few publications deal with the therapy dog experience of AAIs. This paper provides an overview on potential welfare threats that therapy dogs may encounter and presents the results of a review of available studies on welfare indicators for therapy dogs during AAIs. Previous investigations used physiological and behavioral welfare indicators and dog handler surveys to identify work-related stress. Research outcomes are discussed in the light of strengths and weaknesses of the methods used. Study results suggest that frequency and duration of AAI sessions, novelty of the environment, controllability, age and familiarity of recipients modulate animal welfare indicators. However, this review reveals that currently, clear conclusions on how the well-being of dogs is influenced by the performance in AAIs are lacking due to the heterogeneity of programs, recipient and session characteristics, small dog sample sizes and methodological limitations. This paper further aimed to identify unresolved difficulties in previous research to pave the way for future investigations supporting the applicability of scientific findings in practice.

    The prevalence of type 2 diabetes(T2D) is evolving globally at an alarming rate. Prediabetes is an intermediate state of glucose metabolism that exists between normal glucose tolerance(NGT) and the clinical entity of T2 D. Relentless β-cell decline and failure is responsible for the progression from NGT to prediabetes and eventually T2 D. The huge burden resulting from the complications of T2 D created the need of therapeutic strategies in an effort to prevent or delay its development. The beneficial effects of incretin-based therapies, dipeptidyl peptidase-4 inhibitors and glucagon-like peptide-1(GLP-1) receptor agonists, on β-cell function in patients with T2 D, together with their strictly glucose-depended mechanism of action, suggested their possible use in individuals with prediabetes when greater β-cell mass and function are preserved and the possibility of β-cell salvage is higher. The present paper summarizes the main molecular intracellular mechanisms through which GLP-1 exerts its activity on β-cells. It also explores the current evidence of incretin based therapies when administered in a prediabetic state, both in animal models and in humans. Finally it discusses the safety of incretin-based therapies as well as their possible role in order to delay or prevent T2 D.

    2013-01-01

    The current system of International Standards (ISO) is assessed to consider whether standards are fit for purpose for the future in the context of climate change. ISO 7243, ISO 7933 and ISO 9886 provide the current ISO system for the assessment of heat stress. These involve a simple monitoring index, an analytical approach and physiological monitoring, respectively. The system relies on accurate measurement of the thermal conditions experienced by the worker (ISO 7726); and estimations of metabolic heat production due to work (ISO 8996) and the thermal properties of clothing (ISO 9920). As well as standards for heat stress assessment, the full range of ISO standards and the physical environment is listed as well as current work and proposed standards. A particular 'gap' in anticipating requirements for ISO standards in the future is the link between meteorological data and ISO standards. This is important for predicting the global consequences of a changing climate and anticipating potential impacts on occupational health across countries and cultures.

    2011-01-01

    A plethora of studies have examined the efficacy and effectiveness of cognitive-behavioral therapy (CBT) for adult anxiety disorders. In recent years, several meta-analyses have been conducted to quantitatively review the evidence of CBT for anxiety disorders, each using different inclusion criteria for studies, such as use of control conditions or type of study environment. This review aims to summarize and to discuss the current state of the evidence regarding CBT treatment for panic disorder, generalized anxiety disorder, social anxiety disorder, obsessive-compulsive disorder, and post-traumatic stress disorder. Overall, CBT demonstrates both efficacy in randomized controlled trials and effectiveness in naturalistic settings in the treatment of adult anxiety disorders. However, due to methodological issues, the magnitude of effect is currently difficult to estimate. In conclusion, CBT appears to be both efficacious and effective in the treatment of anxiety disorders, but more high-quality studies are needed to better estimate the magnitude of the effect.

    Purpose: There is growing recognition of need for increased clarity and consistency in the nomenclatures used for body and organ structures, DVH metrics, toxicity, dose and volume units, etc. Standardization has multiple benefits; e.g. facilitating data collection for clinical trials, enabling the pooling of data between institutions, making transfers (i.e. hand-offs) between centers safer, and enabling vendors to define “default” settings. Towards this goal, the American Association of Physicists in Medicine (AAPM) formed a task group (TG263) in July of 2014, operating under the Work Group on Clinical Trials to develop consensus statements. Guiding principles derived from the investigation and example nomenclatures will be presented for public feedback. Methods: We formed a multi-institutional and multi-vendor collaborative group of 39 physicists, physicians and others involved in clinical use and electronic transfer of information. Members include individuals from IROC, NRG, IHE-RO, DICOM WG-7, ASTRO and EORTC groups with overlapping interests to maximize the quality of the consensus and increase the likelihood of adoption. Surveys of group and NRG members were used to define current nomenclatures and requirements. Technical requirements of vendor systems and the proposed DICOM standards were examined. Results: There is a marked degree of inter and intra institutional variation in current approaches, resulting from inter-vendor differences in capabilities, clinic specific conceptualizations and inconsistencies. Using a consensus approach, the group defined optimal formats for the naming of targets and normal structures. A formal objective assessment of 13 existing clinically-used software packages show that all had capabilities to accommodate these recommended nomenclatures. Conclusions: A multi-stakeholder effort is making significant steps forward in developing a standard nomenclature that will work across platforms. Our current working list includes > 550

  16. Pathogenesis of metastatic disease: implications for current therapy and for the development of new therapeutic strategies.

    Different tumor cell subpopulations coexisting within the same tumor exhibit varied susceptibilities to antineoplastic agents. Tumor cell heterogeneity is now recognized as the principal cause of treatment failure in cancer, and is a formidable obstacle to effective therapy and to the development of drug delivery systems for selective targeting of antineoplastic agents to tumor cells. Recent insights into the genesis of tumor cell heterogeneity during progressive tumor growth reveal new complexities that raise challenging questions about the adequacy of certain approaches to the current therapy of metastatic disease and impose challenging criteria for the development of improved therapeutic strategies. Many of the experimental approaches used in the search for new antineoplastic agents and targeted drug delivery systems ignore the pathogenesis of metastasis and the problem of tumor cell heterogeneity. The adoption of more relevant assay systems is an urgent priority. These include the greater use of metastatic tumor models and the increased use of human tumor cells to replace rodent cell systems which have been of limited predictive value in identifying effective anticancer agents. In contrast to current strategies for the development of new antineoplastic drugs which seek to identify agents with activity against a broad range of histologically diverse tumors, greater success may be achieved by seeking agents active only against specific cell lineages. Many established human tumor cell lines may not be suitable for this purpose because of extensive phenotypic change produced by prolonged passage ex vivo. Development of histiotype-specific human tumor cell screens will require an extensive research effort to identify target cells that display demonstrable phenotypic relatedness to tumor cells in neoplastic lesions. Major advances in the therapy of metastatic disease are considered unlikely in the next few years, and progress will stem from improved use of existing

    Introduction Outcome studies of endodontic treatment of necrotic immature permanent teeth rely on radiographic measures as surrogates of whether the treatment achieved regeneration/revascularization/revitalization. An increase in radiographic root length and/or width is thought to result in a better long-term prognosis for the tooth. In this study a method to measure radiographic outcomes of endodontic therapies on immature teeth was developed and validated. Methods A standardized protocol was developed for measuring the entire area of the root of immature teeth. The “Radiographic Root Area” (RRA) measurement accounts for the entire surface area of the root as observed on a periapical radiograph. Reviewers were given instructions on how to measure RRA and they completed measurements on a set of standardized radiographs. Results The intra class correlation (ICC) between the four reviewers was 0.9945, suggesting high concordance among reviewers. There was no effect of reviewer on the measured RRA values. High concordance was also observed when one rater repeated the measurements, with an ICC value of 0.9995. There was no significant difference in RRA values measured at the two sessions by the same rater. Furthermore, significant differences in RRA were detectable between clinical cases that demonstrated obvious continued root development and cases that did not demonstrate discernible root development. Conclusions These results suggest that RRA is a valid measure to assess radiographic outcomes in endodontically treated immature teeth, and RRA should be useful in future clinical studies of regenerative endodontic outcomes.

    The aim of the current review is to provide a summary of research into Internet-delivered cognitive behavioral therapy (iCBT) for anxiety disorders. We include 37 randomized controlled trials that examined the efficacy of iCBT programs in adults (aged over 18 years), as compared with waiting list or active control. The included studies were identified from Medline searches and from reference lists, and only published data were included. Several trials of iCBT for generalized anxiety disorder, panic disorder, and social phobia were identified. Two trials of iCBT for obsessive-compulsive disorder were identified, whilst one trial each was identified for hypochondriasis, specific phobia (spiders), and post-traumatic stress disorder. Finally, there were five trials that focused on transdiagnostic therapy for either a range of comorbid anxiety disorders or comorbid anxiety and depression. Between-group effect sizes were moderate to large for all disorders, and ranged from 0.30 to 2.53. iCBT was found to be commensurate with face-to-face cognitive behavioral therapy whether delivered individually or in group format. Guidance may not be necessary for iCBT to be effective for immediate gains, but may be more important in longer-term maintenance of symptom improvement and maximizing patient adherence. The clinical experience of the individual providing guidance does not appear to impact treatment outcomes. Future research needs to focus on the optimal level of guidance required to generate maximum patient benefits, whilst balancing the efficient use of clinician time and resources. Evidence-based contraindications to iCBT should also be developed so that the choice of treatment modality accurately reflects patients’ needs. Further research should be conducted into the effective elements of iCBT, as well as the extent to which therapy enhancers and advancing technology can be accommodated into established iCBT frameworks.

    Age-related macular degeneration (AMD) is the leading cause of vision loss in the industrialized world. In the last few decades, the mainstay of treatment for choroidal neovascularization (CNV) due to AMD has been thermal laser photocoagulation. In the last decade, photodynamic therapy with verteporfin extended treatment for more patients. While both of these treatments have prevented further vision loss in a subset of patients, improvement in visual acuity is rare. Anti-vascular endothelial growth factor A (VEGF) therapy has revolutionized the treatment of AMD-related CNV. Pegaptanib, an anti-VEGF aptamer prevents vision loss in CNV, although the performance is similar to that of photodynamic therapy. Ranibizumab, an antibody fragment and bevacizumab, a full-length humanized monoclonal antibody against VEGF have both shown promising results with improvements in visual acuity with either agent. VEGF trap, a modified soluble VEGF receptor analogue, binds VEGF more tightly than all other anti-VEGF agents and has also shown promising results in early trials. Other treatment strategies to decrease the effect of VEGF have used small interfering ribonucleic acid (RNA) to inhibit VEGF production and VEGF receptor production. Steroids, including anecortave acetate in the treatment and prevention of CNV, have shown promise in controlled trials. Receptor tyrosine kinase inhibitors, such as vatalanib, inhibit downstream effects of VEGF, and have been effective in the treatment of CNV in early studies. Squalamine lactate inhibits plasma membrane ion channels with downstream effects on VEGF, and has shown promising results with systemic administration. Other growth factors, including pigment epithelium-derived growth factor that has been administered via an adenoviral vector has shown promising initial results. In some patients ciliary neurotrophic factor is currently being studied for the inhibition of progression of geographic atrophy. Combination therapy has been

    Full Text Available Palanivel Ganesan,1,2 Dong-Kug Choi1,2 1Department of Applied Life Science, Nanotechnology Research Center, 2Department of Biotechnology, College of Biomedical and Health Science, Konkuk University, Chungju, Republic of Korea Abstract: Phytocompounds have been used in cosmeceuticals for decades and have shown potential for beauty applications, including sunscreen, moisturizing and antiaging, and skin-based therapy. The major concerns in the usage of phyto-based cosmeceuticals are lower penetration and high compound instability of various cosmetic products for sustained and enhanced compound delivery to the beauty-based skin therapy. To overcome these disadvantages, nanosized delivery technologies are currently in use for sustained and enhanced delivery of phyto-derived bioactive compounds in cosmeceutical sectors and products. Nanosizing of phytocompounds enhances the aseptic feel in various cosmeceutical products with sustained delivery and enhanced skin protecting activities. Solid lipid nanoparticles, transfersomes, ethosomes, nanostructured lipid carriers, fullerenes, and carbon nanotubes are some of the emerging nanotechnologies currently in use for their enhanced delivery of phytocompounds in skin care. Aloe vera, curcumin, resveratrol, quercetin, vitamins C and E, genistein, and green tea catechins were successfully nanosized using various delivery technologies and incorporated in various gels, lotions, and creams for skin, lip, and hair care for their sustained effects. However, certain delivery agents such as carbon nanotubes need to be studied for their roles in toxicity. This review broadly focuses on the usage of phytocompounds in various cosmeceutical products, nanodelivery technologies used in the delivery of phytocompounds to various cosmeceuticals, and various nanosized phytocompounds used in the development of novel nanocosmeceuticals to enhance skin-based therapy.

    Full Text Available BACKGROUND: In a randomized clinical trial of early versus standard antiretroviral therapy (ART in HIV-infected adults with a CD4 cell count between 200 and 350 cells/mm³ in Haiti, early ART decreased mortality by 75%. We assessed the cost-effectiveness of early versus standard ART in this trial. METHODS AND FINDINGS: Trial data included use of ART and other medications, laboratory tests, outpatient visits, radiographic studies, procedures, and hospital services. Medication, laboratory, radiograph, labor, and overhead costs were from the study clinic, and hospital and procedure costs were from local providers. We evaluated cost per year of life saved (YLS, including patient and caregiver costs, with a median of 21 months and maximum of 36 months of follow-up, and with costs and life expectancy discounted at 3% per annum. Between 2005 and 2008, 816 participants were enrolled and followed for a median of 21 months. Mean total costs per patient during the trial were US$1,381 for early ART and US$1,033 for standard ART. After excluding research-related laboratory tests without clinical benefit, costs were US$1,158 (early ART and US$979 (standard ART. Early ART patients had higher mean costs for ART (US$398 versus US$81 but lower costs for non-ART medications, CD4 cell counts, clinically indicated tests, and radiographs (US$275 versus US$384. The cost-effectiveness ratio after a maximum of 3 years for early versus standard ART was US$3,975/YLS (95% CI US$2,129/YLS-US$9,979/YLS including research-related tests, and US$2,050/YLS excluding research-related tests (95% CI US$722/YLS-US$5,537/YLS. CONCLUSIONS: Initiating ART in HIV-infected adults with a CD4 cell count between 200 and 350 cells/mm³ in Haiti, consistent with World Health Organization advice, was cost-effective (US$/YLS <3 times gross domestic product per capita after a maximum of 3 years, after excluding research-related laboratory tests.

  2. Use of antiplatelet agents and anticoagulants for cardiovascular disease: current standards and best practices.

    Faxon, David P

    2005-01-01

    Thrombosis superimposed on arteriosclerosis is the principal cause of mortality and morbidity in patients with arteriosclerosis. The use of antiplatelet agents and anticoagulants in the treatment of arteriosclerosis is well established, based on many large randomized trials. Aspirin is indicated for primary prevention in patients at increased risk of developing symptomatic atherosclerotic vascular disease. For patients with known vascular disease, antiplatelet therapy with aspirin is a well-established treatment. For high-risk patients such as those with acute coronary syndromes (ACS; unstable angina, myocardial infarction), dual antiplatelet therapy with aspirin and clopidogrel is indicated, based on results of the Clopidogrel in Unstable Angina to Prevent Recurrent Events (CURE) trial. Platelet glycoprotein IIb/IIIa agents are powerful inhibitors of platelet function and are also effective in ACS, but the benefit is confined to high-risk patients. Anticoagulation with heparin or low-molecular-weight heparin (eg, enoxaparin) is also effective, with an approximately 50% reduction in cardiovascular events. These agents are also indicated for patients undergoing percutaneous coronary intervention. Prolonged dual antiplatelet therapy (at least 6 months) is recommended for patients receiving drug-eluting stents. The efficacy of antiplatelet therapy is thus well established in treating atherothrombosis, but aggressive therapy is associated with an increased bleeding risk. Newer agents may provide improved efficacy with a lower risk of bleeding.

    ABSTRACT Following concurrent radio-chemotherapy or first-line chemotherapy for advanced non-small cell lung cancer(NSCLC), continuous maintenance therapy given to patients with stable disease (SD) and follow-up treatment is called consolidation therapy. Concerning NSCLC patients with a non-operable dry Stage-ⅢB (N3) disease, I.e. Contra-lateral mediastinal and hilar lymph node, or homolateral/contra-lateral scalene and Troisier sign, a 2 or 3-course of standard-dosage Taxotere consolidation therapy can be performed after concurrent radio-chemotherapy. In pursuance of evidence-based medicine (EBM), low-dose Taxoteremaintenance therapy, and biological targeted therapy of patients with appropriate symptoms are suitable for second-line therapy for moist of the Stage-ⅢB (malignant pleural effusion) and Ⅳpatients.

    Although our understanding of multiple sclerosis (MS) has grown substantially, its cause remains unknown. Nonetheless, in the past 3 decades, there have been tremendous advancements in the development of disease-modifying drugs (DMDs). In July 1993, the United States Food and Drug Administration approved the first disease-modifying drug-interferon β- and there are currently 13 medications approved for use in relapsing MS. All the early medications are administered either as a subcutaneous or intramuscular injection, and despite the clinical efficacy and safety of these medications, many patients were hampered by the inconvenience of injections and injection-related side effects. In September 2010, the first oral DMD-fingolimod-was approved. Since then, 2 additional oral DMDs (teriflunomide and dimethyl fumarate) have been approved, and several other oral medications are being evaluated in extensive MS development programs. Because of frequent ocular involvement, ophthalmologists are often involved in the care of MS patients and therefore need to be aware of the current treatment regimens prescribed by neurologists, some of which can have significant ophthalmic adverse events. We update the current advancements in the treatment of MS and discuss the published clinical data on the efficacy and safety of the currently approved and emerging oral therapies in MS.

    Boron-neutron capture therapy (BNCT) is a perspective treatment method for radiation resistant tumors. Unfortunately its development is strongly held back by a several physical and medical problems. Neutron sources for BNCT currently are limited to nuclear reactors and accelerators. For wide spread of BNCT investigations more compact and cheap neutron source would be much more preferable. In present paper an approach for compact D-D neutron generator creation based on a high current ECR ion source is suggested. Results on dense proton beams production are presented. A possibility of ion beams formation with current density up to 600 mA/cm2 is demonstrated. Estimations based on obtained experimental results show that neutron target bombarded by such deuteron beams would theoretically yield a neutron flux density up to 6·1010 cm-2/s. Thus, neutron generator based on a high-current deuteron ECR source with a powerful plasma heating by gyrotron radiation could fulfill the BNCT requirements significantly lower price, smaller size and ease of operation in comparison with existing reactors and accelerators.

    Purpose: To determine the safety of the addition of bevacizumab to standard radiation therapy and daily temozolomide for newly diagnosed glioblastoma multiforme (GBM). Methods and Materials: A total of 125 patients with newly diagnosed GBM were enrolled in the study, and received standard radiation therapy and daily temozolomide. All patients underwent a craniotomy and were at least 2 weeks postoperative. Radiation therapy was administered in 1.8-Gy fractions, with the clinical target volume for the primary course treated to a dose of 45 to 50.4 Gy, followed by a boost of 9 to 14.4 Gy, to a total dose of 59.4 Gy. Patients received temozolomide at 75 mg/m{sup 2} daily throughout the course of radiation therapy. Bevacizumab was given at 10 mg/kg intravenously every 14 days, beginning a minimum of 4 weeks postoperatively. Results: Of the 125 patients, 120 (96%) completed the protocol-specified radiation therapy. Five patients had to stop the protocol therapy, 2 patients with pulmonary emboli, and 1 patient each with a Grade 2 central nervous system hemorrhage, Grade 4 pancytopenia, and wound dehiscence requiring surgical intervention. All 5 patients ultimately finished the radiation therapy. After radiation therapy, 3 patients had progressive disease, 2 had severe fatigue and decreased performance status, 1 patient had a colonic perforation, and 1 had a rectal fissure; these 7 patients therefore did not proceed with the protocol-specified adjuvant temozolomide, bevacizumab, and irinotecan. However, 113 patients (90%) were able to continue on study. Conclusions: The addition of bevacizumab to standard radiation therapy and daily temozolomide was found to be associated with minimal toxicity in patients newly diagnosed with GBM.

    Magee, Wendy L; O'Kelly, Julian

    2015-03-01

    Patients with prolonged disorders of consciousness (PDOC) stemming from acquired brain injury present one of the most challenging clinical populations in neurological rehabilitation. Because of the complex clinical presentation of PDOC patients, treatment teams are confronted with many medicolegal, ethical, philosophical, moral, and religious issues in day-to-day care. Accurate diagnosis is of central concern, relying on creative approaches from skilled clinical professionals using combined behavioral and neurophysiological measures. This paper presents the latest evidence for using music as a diagnostic tool with PDOC, including recent developments in music therapy interventions and measurement. We outline standardized clinical protocols and behavioral measures to produce diagnostic outcomes and examine recent research illustrating a range of benefits of music-based methods at behavioral, cardiorespiratory, and cortical levels using video, electrocardiography, and electroencephalography methods. These latest developments are discussed in the context of evidence-based practice in rehabilitation with clinical populations. © 2014 New York Academy of Sciences.

    In the last 20 years, several clinical trials on neoadjuvant chemotherapy and chemo-radiotherapy as a therapeutic approach for locally advanced gastric cancer have been performed. Even if more data are necessary to define the roles of these approaches, the results of preoperative treatments in the combined treatment of gastric adenocarcinoma are encouraging because this approach has led to a higher rate of curative surgical resection. Owing to the results of most recent randomized phase III studies, neoadjuvant chemotherapy for locally advanced resectable gastric cancer has satisfied the determination of level I evidence. Remaining concerns pertain to the choice of the optimal therapy regimen, strict patient selection by accurate pre-operative staging, standardization of surgical procedures, and valid criteria for response evaluation. New well-designed trials will be necessary to find the best therapeutic approach in pre-operative settings and the best way to combine old-generation chemotherapeutic drugs with new-generation molecules.

    Full Text Available The aim of the present study was to assess the degree and impact of patient selection of patients with intermittent claudication undergoing supervised exercise therapy in Randomized Controlled Trials (RCTs by describing commonly used exclusion criteria, and by comparing baseline characteristics and treatment response measured as improvement in maximum walking distance of patients included in RCTs and patients treated in standard care.We compared data from RCTs with unselected standard care data. First, we systematically reviewed RCTs that investigated the effect of supervised exercise therapy in patients with intermittent claudication. For each of the RCTs, we extracted and categorized the eligibility criteria and their justifications. To assess whether people in RCTs (n = 1,440 differed from patients treated in daily practice (n = 3,513, in terms of demographics, comorbidity and walking capacity, we assessed between group-differences using t-tests. To assess differences in treatment response, we compared walking distances at three and six months between groups using t-tests. Differences of ≥15% were set as a marker for a clinically relevant difference.All 20 included RCTs excluded large segments of patients with intermittent claudication. One-third of the RCTs eligibility criteria were justified. Despite, the numerous eligibility criteria, we found that baseline characteristics were largely comparable. A statistically significant and (borderline clinically relevant difference in treatment response after three and six months between trial participants and standard care patients was found. Improvements in maximum walking distance after three and six months were significantly and clinically less in trial participants.The finding that baseline characteristics of patients included in RCTs and patients treated in standard care were comparable, may indicate that RCT eligibility criteria are used implicitly by professionals when referring patients to

    2014-06-07

    Parkinson's disease is a common movement disorder affecting approximately 127,000 people in the UK, with an estimated two thirds having speech-related problems. Currently there is no preferred approach to speech and language therapy within the NHS and there is little evidence for the effectiveness of standard NHS therapy or Lee Silverman voice treatment. This trial aims to investigate the feasibility and acceptability of randomizing people with Parkinson's disease-related speech or voice problems to Lee Silverman voice treatment or standard speech and language therapy compared to a no-intervention control. The PD COMM pilot is a three arm, assessor-blinded, randomized controlled trial. Randomization will be computer-generated with participants randomized at a ratio of 1:1:1. Participants randomized to intervention arms will be immediately referred to the appropriate speech and language therapist. The target population are patients with a confirmed diagnosis of idiopathic Parkinson's disease who have problems with their speech or voice. The Lee Silverman voice treatment intervention group will receive the standard regime of 16 sessions between 50 and 60 minutes in length over four weeks, with extra home practice. The standard speech and language therapy intervention group will receive a dose determined by patients' individual needs, but not exceeding eight weeks of treatment. The control group will receive standard care with no speech and language therapy input for at least six months post-randomization. Outcomes will be assessed at baseline (pre-randomization) and post- randomization at three, six, and 12 months. The outcome measures include patient-reported voice measures, quality of life, resource use, and assessor-rated speech recordings. The recruitment aim is at least 60 participants over 21 months from 11 sites, equating to at least 20 participants in each arm of the trial. This trial is ongoing and recruitment commenced in May 2012. This study will

    2015-12-01

    The aim of this metaanalysis was to investigate the effectiveness of extracorporeal shock wave therapy (ESWT) in cellulite. Electronic databases (such as Ovid MEDLINE, Scopus and Ovid) as well as reference lists of the available studies were evaluated in June 2015 by two expert examiners. Assessment of each study's methodological quality was performed with the help of the published quality index tool by Downs and Black. This metanalysis included a total of eleven clinical trials on the effects of ESWT on cellulite with a total of 297 included females. Among the eleven clinical trials five randomized controlled trials on ESWT in cellulite with a total number of 123 females have been published so far. Both, focused as well as radial ESWT devices have been found effective in treating cellulite so far. Typically, one or two sessions per week and six to eight sessions overall were studied in the published clinical trials. Overall, outcome parameters mainly focused on digital standardized photographs, circumference measurements and specific ultrasound examinations. Reporting quality showed substantial heterogenity from 22 to 82 points with a mean of 57 points. This metanalysis identified eleven published clinical studies on ESWT in cellulite with five randomized-controlled trials among them. There is growing evidence that both, radial as well as focused ESWT and the combination of both are able to improve the degree of cellulite. Typically, six to eight treatments once or twice a week have been studied. Long-term follow-up data beyond one year are lacking as well as details on potential combination therapies in cellulite such as with low level laser therapy (LLLT), cryolipolysis and others.

    Urinary tract infections and urosepsis are complications which can precede or follow a kidney stone treatment. Often the stones themselves are the source of infection, whether they are infection stones or not. Systemic infections are difficult to foresee, and neither a pre-operative negative urine culture nor an antibiotic prophylaxis avoid infectious complications for certain. The primary predictive risk factors of urosepsis are: patient conditions, urinary tract infection or a history of recurrent infections, characteristics of the stone, and anatomy of the urinary tract. Infection stones are still a matter of debate, concerning both the aetiology of the disease and its treatment. Positive cultures are not only found with struvite stones, but also with apatite and calcium oxalate stones. Currently, a long-term antibiotic therapy is advised in patients affected by infection stones. Antibiotic therapy should prevent not only septic complications but also recurrence or re-growth of stones after treatment. Different antibiotic modalities are recommended, sometimes together with urease inhibitors. Mid-stream urine culture is the easiest available pre-treatment parameter notwithstanding its poor predictive value. In case of suspected or proven urinary infection, an appropriate antibiotic therapy should always be administered prior to surgical procedure. There is, however, controversy regarding the antibiotic use, its role, expediency, and duration of prophylaxis in relation to the various surgical procedures, and the way infectious complications are considered and classified. When antibiotic prophylaxis is considered, its duration should be clearly established prior to surgery; duration may vary depending on the type of surgery or the type of antibiotic. Furthermore, prophylaxis should be administered only for a limited amount of time.

    Full Text Available Louise Mewton, Jessica Smith, Pieter Rossouw, Gavin Andrews Clinical Research Unit for Anxiety and Depression, St Vincent’s Hospital, Sydney, NSW, Australia Abstract: The aim of the current review is to provide a summary of research into Internet-delivered cognitive behavioral therapy (iCBT for anxiety disorders. We include 37 randomized controlled trials that examined the efficacy of iCBT programs in adults (aged over 18 years, as compared with waiting list or active control. The included studies were identified from Medline searches and from reference lists, and only published data were included. Several trials of iCBT for generalized anxiety disorder, panic disorder, and social phobia were identified. Two trials of iCBT for obsessive-compulsive disorder were identified, whilst one trial each was identified for hypochondriasis, specific phobia (spiders, and post-traumatic stress disorder. Finally, there were five trials that focused on transdiagnostic therapy for either a range of comorbid anxiety disorders or comorbid anxiety and depression. Between-group effect sizes were moderate to large for all disorders, and ranged from 0.30 to 2.53. iCBT was found to be commensurate with face-to-face cognitive behavioral therapy whether delivered individually or in group format. Guidance may not be necessary for iCBT to be effective for immediate gains, but may be more important in longer-term maintenance of symptom improvement and maximizing patient adherence. The clinical experience of the individual providing guidance does not appear to impact treatment outcomes. Future research needs to focus on the optimal level of guidance required to generate maximum patient benefits, whilst balancing the efficient use of clinician time and resources. Evidence-based contraindications to iCBT should also be developed so that the choice of treatment modality accurately reflects patients’ needs. Further research should be conducted into the effective elements of

    Purpose: Older patients with newly diagnosed glioblastoma have poor outcomes, and optimal treatment is controversial. Hypofractionated radiation therapy (HRT) is frequently used but has not been compared to patients receiving standard fractionated radiation therapy (SRT) and temozolomide (TMZ). Methods and Materials: We conducted a retrospective analysis of patients ≥65 years of age who received radiation for the treatment of newly diagnosed glioblastoma from 1994 to 2013. The distribution of clinical covariates across various radiation regimens was analyzed for possible selection bias. Survival was calculated using the Kaplan-Meier method. Comparison of hypofractionated radiation (typically, 40 Gy/15 fractions) versus standard fractionation (typically, 60 Gy/30 fractions) in the setting of temozolomide was conducted using Cox regression and propensity score analysis. Results: Patients received SRT + TMZ (n=57), SRT (n=35), HRT + TMZ (n=34), or HRT (n=9). Patients receiving HRT were significantly older (median: 79 vs 69 years of age; P<.001) and had worse baseline performance status (P<.001) than those receiving SRT. On multivariate analysis, older age (adjusted hazard ratio [AHR]: 1.06; 95% confidence interval [CI]: 1.01-1.10, P=.01), lower Karnofsky performance status (AHR: 1.02; 95% CI: 1.01-1.03; P=.01), multifocal disease (AHR: 2.11; 95% CI: 1.23-3.61, P=.007), and radiation alone (vs SRT + TMZ; SRT: AHR: 1.72; 95% CI: 1.06-2.79; P=.03; HRT: AHR: 3.92; 95% CI: 1.44-10.60, P=.007) were associated with decreased overall survival. After propensity score adjustment, patients receiving HRT with TMZ had similar overall survival compared with those receiving SRT with TMZ (AHR: 1.10, 95% CI: 0.50-2.4, P=.82). Conclusions: With no randomized data demonstrating equivalence between HRT and SRT in the setting of TMZ for glioblastoma, significant selection bias exists in the implementation of HRT. Controlling for this bias, we observed similar overall

    Full Text Available Menopause occurs naturally when the ovary ceases folliculogenesis, or artificially by surgical and/or medical ablation of the ovarian function. Menopause is a hypoestrogenic state, which may adversely affect estrogen target tissues, such as the brain, skeleton and skin, as well as the cardiovascular and genitourinary systems, with resultant frequency and severity of climacteric symptoms. The climacteric symptoms, however, vary significantly among women. For decades, hormone therapy (HT has been the mainstay and is considered the most effective for managing menopausal symptoms. The prolonged use of either single estrogen therapy or a combination therapy of estrogen and progestogen (EPT might be associated with a slightly increased risk of breast cancer and many resultant adverse events, such as coronary heart disease, stroke and venous thromboembolism. Perhaps because the clear benefits are limited to these end points of HT in treating menopausal women, the relatively significant adverse event profiles of these women may not be enough to trigger primary care physicians to be more aggressive than they have been to date in treating climacteric symptoms of postmenopausal women. However, severe climacteric symptoms really disturb the woman's life. Some epidemiologic studies have shown that the increased risk for breast cancer after 5 years of combined EPT is similar in magnitude to other lifestyle variables, such as 10-year delayed menopause, fewer pregnancies and reduced breastfeeding, postmenopausal obesity, excessive alcohol or cigarette use, and lack of regular exercise. Furthermore, elevated serum concentrations of either endogenous or exogenous (replaced by HT sex hormone in either pre- or postmenopausal women are associated with an increased risk of breast cancer. Finally, the increased breast cancer risk diminishes soon after discontinuing hormones, and largely disappears by 5 years after cessation. Taken together, low-dose conventional HT

    Since December 2009 a new VMAT planning system tool is available in Oncentra MasterPlan v3.3 (Nucletron B.V.). The purpose of this study was to work out standard parameters for the optimization of prostate cancer. For ten patients with localized prostate cancer plans for simultaneous integrated boost were optimized, varying systematically the number of arcs, collimator angle, the maximum delivery time, and the gantry spacing. Homogeneity in clinical target volume, minimum dose in planning target volume, median dose in the organs at risk, maximum dose in the posterior part of the rectum, and number of monitor units were evaluated using student's test for statistical analysis. Measurements were performed with a 2D-array, taking the delivery time, and compared to the calculation by the gamma method. Plans with collimator 45° were superior to plans with collimator 0°. Single arc resulted in higher minimum dose in the planning target volume, but also higher dose values to the organs at risk, requiring less monitor units per fraction dose than dual arc. Single arc needs a higher value (per arc) for the maximum delivery time parameter than dual arc, but as only one arc is needed, the measured delivery time was shorter and stayed below 2.5 min versus 3 to 5 min. Balancing plan quality, dosimetric results and calculation time, a gantry spacing of 4° led to optimal results. A set of parameters has been found which can be used as standard for volumetric modulated arc therapy planning of prostate cancer.

    The discovery that a number of aberrant tumorigenic processes and signal transduction pathways are mediated by druggable protein kinases has led to a revolutionary change in nonsmall cell lung cancer (NSCLC) treatment. Epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) are the targets of several tyrosine kinase inhibitors (TKIs), some of them approved for treatment and others currently in clinical development. First-generation agents offer, in target populations, a substantial improvement of outcomes compared with standard chemotherapy in the treatment of advanced NSCLC. Unfortunately, drug resistance develops after initial benefit through a variety of mechanisms. Novel generation EGFR and ALK inhibitors are currently in advanced clinical development and are producing encouraging results in patients with acquired resistance to previous generation agents. The search for new drugs or strategies to overcome the TKI resistance in patients with EGFR mutations or ALK rearrangements is to be considered a priority for the improvement of outcomes in the treatment of advanced NSCLC.

    Full Text Available The rational use of antibiotics in the treatment of orthopedic infection still presents a significant problem. Local antibiotic delivery systems enable to achieve effective concentrations of drugs in the focus of bone infection without the development of toxicity. It is the important accompaniment to systemic antibiotics in the treatment of periprosthetic infection and osteomyelitis. The data collected through the PubMed and eLIBRARY databases (http://www.ncbi.nlm. nih.gov/pubmed, 1995-2015; http://elibrary.ru, 2005-2015 years present the information about bone substitutes used for local antibiotic therapy in scientific investigations and in clinical practice. The information is submitted in accordance with the groups of materials: cements based on polymethylmethacrylate, bone grafts, demineralized bone matrix, bioceramics, natural and synthetic polymers, combined antibiotic delivery systems. The majority of these materials have only been studied experimentally and only a limited range of them is registered for use in clinical practice. Informing orthopedic surgeons about current methods of local antibiotic use is the key to the development of a modern integrated approach to the therapy of infectious complications after orthopedic surgery.

    Hypogonadal men are characterized by low serum testosterone and symptoms of low energy, decreased libido, and muscle mass as well as impaired concentration and sexual functioning. Men with prostate cancer (PCa) currently on active surveillance or post-therapy, have traditionally been excluded from management paradigms given the decade-old concern that testosterone caused PCa growth. However, there appears to be little or no relationship between serum testosterone concentration and PCa. Androgen action in the prostate has long been known to be affected by the kinetics of receptor saturation and, as such, testosterone beyond a certain baseline is unable to stimulate prostatic growth due to complete intra-prostatic androgen receptor binding. Given this physiologic concept, many clinical investigators have begun to promote testosterone supplementation therapy (TST) as safe in men with PCa. This review examines the basics of testosterone physiology and summarizes the most recent findings on the use of TST in men with PCa on active surveillance and following treatment with external beam radiotherapy, brachytherapy and radical prostatectomy.

    Neuromyelitis optica (NMO, Devic-syndrome) is a rare, relapsing autoimmune disease of the central nervous system, which is distinguished from other demyelinating disorders by a recently identified, specific autoantibody. By demonstrating the anti-aquaporin-4 IgG in the serum, a heterogenous group of syndromes can be defined, called NMO-spectrum. In the future, optical coherence tomography may support this diagnosis besides the clinical features, imaging examinations and presence of serum antibody. Early recognition and treatment can improve clinical outcome even in serious condition. Long-term immunosuppressive therapy is advised to prevent further relapses and to stabilize or improve clinical status. Hereby, we report a case of a 51-year-old woman, under treatment for one and a half years. We summarize the current knowledge about the pathomechanism, diagnostic strategy and therapy of neuromyelitis optica. We review recent findings and the diagnostic value of a new, non-invasive ophtalmological examination, the optical coherence tomography. According to the first results, this method may be helpful in the early differential diagnosis of optic neuritis.

    Herpes labialis is a common skin infective condition, worldwide, which is primarily caused by HSV-1. Recurrent episodes of herpes labialis, also known as cold sores, can be frequent, painful, long-lasting and disfiguring for infected patients. At present, there are two types of antivirals for the treatment of herpes labialis, topical and oral, which are available over the counter or as prescription-only. The aim of antiviral therapy is to block viral replication to enable shortening the duration of symptoms and to accelerate healing of the lesions associated with herpes labialis. This review examines the evidence for the effectiveness of current topical and oral antivirals in the management of recurrent episodes of herpes labialis. In most countries, oral antivirals for herpes labialis are available as prescription-only. However, in early 2010, the oral antiviral famciclovir was reclassified from prescription-only medicine to pharmacist-controlled status in New Zealand. The benefits and risks associated with moving an antiviral therapy for herpes labialis from prescription-only to pharmacist-controlled status are reviewed here, and the implications for patients, general physicians and pharmacists are considered.

    Gold nanoparticles (AuNPs) are attractive photothermal agents for cancer therapy because they show efficient local heating upon excitation of surface plasmon oscillations. The strong absorption, efficient heat conversion, high photostability, inherent low toxicity and well-defined surface chemistry of AuNPs contribute to the growing interest in their photothermal therapy (PTT) applications. The facile tunability of gold nanostructures enables engineering of AuNPs for superior near-infrared photothermal efficacy and target selectivity, which guarantee efficient and deep tissue-penetrating PTT with mitigated concerns regarding side effects by nonspecific distributions. This article discusses the current research findings with representative near-infrared-active AuNPs, which include nanoshell, nanorod, nanocage, nanostar, nanopopcorn and nanoparticle assembly systems. AuNPs successfully demonstrate potential for use in PTT, but several hurdles to clinical applications remain, including long-term toxicity and a need for sophisticated control over biodistribution and clearance. Future research directions are discussed, especially regarding the clinical translation of AuNP photosensitizers.

It covers the current views of the role of chronobiological mechanisms in the regulation of sleep and awakening in PD. The results of a follow-up of 20 patients (aged 58.56+8.24 years diagnosed with PD without dementia with subjective nocturnal sleep disorders (disease history was 4.44+3.46 years; PD stage, 2.5+0.47 are given. In addition to antiparkinsonian drugs, melatonin was given in a dose of 3 mg/day. The efficiency of the therapy was evaluated by clinical assessment procedures before and 4—8 weeks after administration of the drug. The therapy outcome was better sleep characteristics in 17 (85% patients, as evidenced by specialized questionnaires. The positive therapeutic effect as judged by the changes in Parkinson's disease sleep scale scores was shown by improvement of subjective sleep quality, reductions in awakening difficulties, in the total number of nocturnal awakening, in the degree of restlessness in bed, which mimics akathisia, and in the frequency of awakenings that were associated by the patients with urges to urinate (p<0.05.

    Synovial sarcoma is a rare soft tissue sarcoma characterized by a t(X;18) translocation, which results in a SYT-SSX gene fusion. In the metastatic setting, chemotherapy has limited, durable efficacy prompting the necessity for new therapeutic modalities. One emerging new strategy involves T-cell-directed therapy such as tumor-infiltrating lymphocytes or the development of T cells that are genetically engineered to express a T-cell receptor against a cancer testis antigen. Of these approaches, engineered T cells that recognize NY-ESO-1 are the furthest along in development. Completed and on-going clinical trials have shown promise and there are efforts to continue to optimize the current approach.

    Wound healing is a complex event that develops in three overlapping phases: inflammatory, proliferative, and remodeling. These phases are distinct in function and histological characteristics. However, they depend on the interaction of cytokines, growth factors, chemokines, and chemical mediators from cells to perform regulatory events. In this article, we will review the pathway in the skin healing cascade, relating the major chemical inflammatory mediators, cellular and molecular, as well as demonstrating the local and systemic factors that interfere in healing and disorders associated with tissue repair deficiency. Finally, we will discuss the current therapeutic interventions in the wounds treatment, and the alternative therapies used as promising results in the development of new products with healing potential.

    Full Text Available The authors have analyzed the literature dealing with studies of the efficiency and safety of stem cell transplantation (SCT in patients with ankylosing spondylitis (AS through the electronic resources Pubmed and Medline by using the keywords «bone marrow transplantation», «hematopoietic stem cell transplantation», «ankylosing spondylitis», «autoimmune diseases», and «sacroiliac joint biopsy». The paper describes four cases of SCT in AS patients, including transplantation that was carried out in one patient with lymphoma concurrent with AS, in two AS patients without blood cancers, and in one patient with AS concurrent with myeloid leukemia. Drug-free remission was achieved in 3 cases: lymphoma concurrent with AS (n=1, AS concurrent with myeloid leukemia (n=1, and AS without comorbidities (n=1. In addition to an improvement in the course of AS, there were also two cases with clinical presentations of AS after SCT. The given cases show that SCT can be basically used to induce drug-free remission in patients with severe forms of standard therapy-resistant AS. However, the introduction of SCT in clinical practice needs to adjust the technique to the specific features of AS patients.

    On their plasma membranes, cells express receptor proteins with high affinity for regulatory peptides, such as somatostatin. Changes in the density of these receptors during disease, e.g. overexpression in many tumours, provide the basis for new imaging methods. The first peptide analogues successfully applied for visualisation of receptor-positive tumours were radiolabelled somatostatin analogues. The next step was to label these analogues with therapeutic radionuclides for peptide receptor radionuclide therapy (PRRT). Results from preclinical and clinical multicentre studies have already shown an effective therapeutic response when using radiolabelled somatostatin analogues to treat receptor-positive tumours. Infusion of positively charged amino acids reduces kidney uptake, enlarging the therapeutic window. For PRRT of CCK-B receptor-positive tumours, such as medullary thyroid carcinoma, radiolabelled minigastrin analogues are currently being successfully applied. The combination of different therapy modalities holds interest as a means of improving the clinical therapeutic effects of radiolabelled peptides. The combination of different radionuclides, such as {sup 177}Lu- and {sup 90}Y-labelled somatostatin analogues, to reach a wider tumour region of high curability, has been described. A variety of other peptide-based radioligands, such as bombesin and NPY(Y{sub 1}) analogues, receptors for which are expressed on common cancers such as prostate and breast cancer, are currently under development and in different phases of (pre)clinical investigation. Multi-receptor tumour targeting using the combination of bombesin and NPY(Y{sub 1}) analogues is promising for scintigraphy and PRRT of breast carcinomas and their lymph node metastases. (orig.)

    To assess the cost-effectiveness of sensor-augmented insulin pump therapy with "Low Glucose Suspend" (LGS) functionality versus standard pump therapy with self-monitoring of blood glucose in patients with type 1 diabetes who have impaired awareness of hypoglycemia. A clinical trial-based economic evaluation was performed in which the net costs and effectiveness of the two treatment modalities were calculated and expressed as an incremental cost-effectiveness ratio (ICER). The clinical outcome of interest for the evaluation was the rate of severe hypoglycemia in each arm of the LGS study. Quality-of-life utility scores were calculated using the three-level EuroQol five-dimensional questionnaire. Resource use costs were estimated using public sources. After 6 months, the use of sensor-augmented insulin pump therapy with LGS significantly reduced the incidence of severe hypoglycemia compared with standard pump therapy (incident rate difference 1.85 [0.17-3.53]; P = 0.037). Based on a primary randomized study, the ICER per severe hypoglycemic event avoided was $18,257 for all patients and $14,944 for those aged 12 years and older. Including all major medical resource costs (e.g., hospital admissions), the ICERs were $17,602 and $14,289, respectively. Over the 6-month period, the cost per quality-adjusted life-year gained was $40,803 for patients aged 12 years and older. Based on the Australian experience evaluating new interventions across a broad range of therapeutic areas, sensor-augmented insulin pump therapy with LGS may be considered a cost-effective alternative to standard pump therapy with self-monitoring of blood glucose in hypoglycemia unaware patients with type 1 diabetes.

    In patients with recurrent or metastatic differentiated thyroid carcinoma, residual disease despite repetitive fixed dose I-131 therapy presents an awkward situation in terms of treatment decision making. Maximal safe dose (MSD) administration base on bone marrow radiation allows the delivery of a large amount I-131 to thyroid cancer tissue within the safety margin. We investigated the efficacy of MSD in differentiated thyroid cancers, which had persisted after conventional fixed dose therapy. Forty-six patients with differentiated thyroid carcinoma who had non-responsible residual disease despite repetitive fixed dose I-131 therapy were enrolled in this study. The postoperative pathology consisted of 43 papillary carcinomas and 3 follicular carcinomas. MSD was calculated according the Memorial Sloan Kettering Cancer Center protocol using blood samples. MSDs were administered at intervals of at least 6 months. Treatment responses were evaluated using I-131 whole body scan (WBS) and serum thyroglobulin measurements. Mean calculated MSD was 12.5{+-}2.1 GBq. Of the 46 patients, 6 (13.0%) showed complete remission, 15 (32.6%) partial response, 19 (41.3%) stable disease, and 6 (13.0%) disease progression. Thus, about a half of the patients showed complete or partial remission, and of these patients, 14 (67%) showed response after a single MSD administration and 6 (29%) showed response after the second dose of MSD administrations. Twenty-nine patients (63%) experienced transient cytopenia after therapy, and recovered spontaneously with the exception of one. MSD administration is an effective method even in the patients who failed to be treated by conventional fixed dose therapy. MSD therapy of I-131 can be considered in the patients who failed by fixed dose therapy.

    Full Text Available The article analyzed the process of reforming the system of accounting and reporting in Ukraine in accordance with International Financial Reporting Standards. The main results of the tasks of the Strategy of application IFRS in Ukraine approved by the Cabinet of Ministers of Ukraine in 2007 are identified. The results of analysis showed that only 1% of the total number of enterprises form the financial statements in accordance with IFRS, the others apply national standards of accounting. The proportion of small enterprises is 95% that do not have the financial capacity, qualified staff and the necessary motivation for the formation of financial statements in accordance with IFRS. As a result, one of the main objectives of the reform of the accounting and reporting is to improve the legislation on accounting for small enterprises and develop national accounting standards of the simplified procedure for accounting of assets, liabilities, equity and financial results of the calculation for small enterprises.

    We empirically surveyed and analyzed existing standards for the treatment of perpetrators of domestic violence across the United States. Specific areas examined included: presence and scope; administrative entity for certifying; screening and risk assessment protocols; minimum length of treatment; theoretical or conceptual orientation; treatment content; preferred or allowable modalities of treatment; whether research findings are mentioned; methods for revising standards; and minimum education and training required for providers. We examined trends using several methods including comparisons between present and previous survey data (Maiuro et al., 2001). Positive trends were evident including increased use of multivariate models of treatment content, use of an intake assessment prior to treatment, use of a danger/lethality assessment to manage risk, recognition of the need for program evaluation and supportive research, and the requirement of a minimum level of formal education as a prerequisite for providers. We identify specific areas for further research and development and make recommendations for improving existing practice and standards of care.

    will require: (1) sophisticated target delineation that integrates CT, MRI and PET imaging; (2) reliable RBE modeling algorithms; (3) efficient beam-scanning technology that compensates for organ movements; (4) online beam control proximal to and within the patient; and (5) better understanding of dose-fractionation parameters. The current status and the anticipated future directions of the role of particle therapy in medicine is a complex subject that involves a very intimate interplay of radiobiology, accelerator physics and radiation oncology. The intention of this relatively brief manuscript is to describe the underlying principles, present the historical developments, highlight the clinical results, focus on the technical advances, and suggest likely future directions. We have also attempted to present a balanced, consensus view of the past achievements and current strategies in particle therapy, in a manner of interest both to long-term experts and to educated newcomers to this field.

    Full Text Available Background/Aim. Complex regional pain syndrome type I (CRPS I is characterized by continuous regional pain, disproportional according to duration and intensity and to the sort of trauma or other lesion it was caused by. The aim of the study was to evaluate and compare, by using thermovison, the effects of low level laser therapy and therapy with interferential current in treatment of CRPS I. Methods. The prospective randomized controlled clinical study included 45 patients with unilateral CRPS I, after a fracture of the distal end of the radius, of the tibia and/or the fibula, treated in the Clinical Centre in Nis from 2004 to 2007. The group A consisted of 20 patients treated by low level laser therapy and kinesy-therapy, while the patients in the group B (n = 25 were treated by interferential current and kinesy-therapy. The regions of interest were filmed by a thermovision camera on both sides, before and after the 20 therapeutic procedures had been applied. Afterwards, the quantitative analysis and the comparing of thermograms taken before and after the applied therapy were performed. Results. There was statistically significant decrease of the mean maximum temperature difference between the injured and the contralateral extremity after the therapy in comparison to the status before the therapy, with the patients of the group A (p < 0.001 as well as those of the group B (p < 0.001. The decrease was statistically significantly higher in the group A than in the group B (p < 0.05. Conclusions. By the use of the infrared thermovision we showed that in the treatment of CRPS I both physical medicine methods were effective, but the effectiveness of laser therapy was statistically significantly higher compared to that of the interferential current therapy.

    2013-07-01

    Gastroenterologists are expected to play a pivotal role in the management of the global obesity epidemic in coming years as novel endoscopic approaches become more widely available, safe, and effective. This review focuses on the recent advances in the field of endoluminal therapy as a primary approach to obesity management with the aim of providing the interventional endoscopist an overview of currently available evidence along with an insight into upcoming devices and techniques. The intragastric balloon appears to be safe and effective in the short term, especially as a bridge to bariatric surgery. Although early trials support the safety and feasibility of endoscopic gastroplasty, it is technically demanding and staple-line dehiscence continues to be a problem. Moreover, with ongoing technical innovations, most devices that have been used in published trials are no longer manufactured and results of studies using newer endoscopic suturing systems are currently awaited. The duodenojejunal bypass sleeve mimics the physiology of intestinal bypass and shares the metabolic advantages of intestinal diversion. A high rate of premature device withdrawal has been its major limiting factor. Therapeutic endoscopy may be the next paradigm of bariatric care. Combining restrictive and barrier endoscopic techniques can potentially improve efficacy and should be evaluated in the setting of appropriate clinical trials.

    Four million people of the global total of 35 million with HIV infection are from South-East Asia. ART is currently utilized by 15 million people and has led to a dramatic decline in the mortality rate, including those in low- and middle-income countries. A reduction in sexually transmitted HIV and in comorbidities including tuberculosis has also followed. Current recommendations for the initiation of antiretroviral therapy in people who are HIV+ are essentially to initiate ART irrespective of CD4 cell count and clinical stage. The frequency of HIV testing should be culturally specific and based on the HIV incidence in different key populations but phasing in viral load technology in LMIC is an urgent priority and this needs resources and capacity. With the availability of simplified potent ART regimens, persons with HIV now live longer. The recent WHO treatment guidelines recommending routine HIV testing and earlier initiation of treatment should be the stepping stone for ending the AIDS epidemic and to meet the UNAIDS mission of 90*90*90.

    Full Text Available β-thalassemias and sickle cell anemia (SCA are the most common monogenic diseases worldwide for which curative treatments remain a desired goal. Allogeneic hematopoietic stem cell transplantation (allo-HCT, - the only curative treatment currently available for hemoglobinopaties-, has a narrow application window whereas it incurs several immunological risks. Gene therapy (GT, that is the autologous transplantation of genetically modified hematopoietic stem cells (CD34+, represents a promising new therapeutic strategy which is anticipated to reestablish effective hemoglobin production and render patients transfusion- and drug- independent without the immunological complications that normally accompany allo-HCT. Prior to the application of GT for hemoglobinopathies in the clinic, many years of extensive preclinical research were spent for the optimization of the gene transfer tools and conditions. To date, three GT clinical trials for β-thalassemia and sickle cell disease (SCD have been conducted or are in progress and 3 cases of transfusion independence in thalassemic β0/βΕ patients have been reported. In the present review, the prerequisites for successful implementation of GT, the tough pathway of GT for hemoglobinopathies towards the clinic and the knowledge gained from the first clinical trials as well as the remaining questions and challenges, will be discussed. Overall, after decades of research including achievements but pitfalls as well, the path to GT of human patients with hemoglobinopathies is currently open and highly promising...

  14. Neuroendocrine tumors:current therapies, notch signaling, and cancer stem cells

    2016-01-01

    Neuroendocrine tumors (NETs) encompass a broad spectrum of malignancies all derived from neuroendocrine cell lineage, affecting many different organs including the gastrointestinal (GI) tract, the endocrine pancreas, the thyroid, the skin and the respiratory tract. These tumors as a group are very heterogeneous, with varying characteristics attributed to each tissue of origin and tumor subtype. The pathogenesis of the different subtypes of NETs is not fully understood, but recent studies suggest the Notch signaling pathway may be dysregulated in these tumors either by under or overexpression of Notch receptors and/or ligands, or by disruption of pathway functionality through other means. Notch receptors can function as tumor suppressors in some cellular contexts and oncogenes in others which may, in part, account for the wide range of phenotypes present in NETs. Cancer stem cells are present in these tumors and may be responsible for the high rate of chemotherapy resistance, recurrence and metastasis. The heterogeneity of NETs suggests that to fully understand the role of Notch signaling and the therapeutic implications thereof, a comprehensive and systematic analysis of Notch expression and function across all NET subtypes is required. Here we outline the current knowledge base with respect to current therapies and Notch signaling in neuroendocrine tumors of the lung, skin, thyroid, GI tract and endocrine pancreas.

    Robotic therapy can improve upper limb function in hemiparesis. Excitatory transcranial direct current stimulation (tDCS) can prime brain motor circuits before therapy. We tested safety and efficacy of tDCS plus robotic therapy in an adult with unilateral spastic cerebral palsy (USCP). In each of 36 sessions, anodal tDCS (2 mA, 20 min) was applied over the motor map of the affected hand. Immediately after tDCS, the participant completed robotic therapy, using the shoulder, elbow, and wrist (MIT Manus). The participant sat in a padded chair with affected arm abducted, forearm supported, and hand grasping the robot handle. The participant controlled the robot arm with his affected arm to move a cursor from the center of a circle to each of eight targets (960 movements). Motor function was tested before, after, and six months after therapy with the Wolf Motor Function Test (WMFT) and Fugl-Meyer (FM). Reaching accuracy on the robot task improved significantly after therapy. The WMFT and FM improved clinically meaningful amounts after therapy. The motor map of the affected hand expanded after therapy. Improvements were maintained six months after therapy. Combined tDCS and robotics safely improved upper limb function in an adult with USCP.

    The use of physical employment standards (PES) has helped ensure that workers have the physical attributes necessary to complete their jobs in a safe and efficient manner. However, PES used in the selection processes have not always reflected the critical physical requirements of the job tasks. Women generally have smaller anthropometric stature than men, less muscle mass, and therefore less strength, power, and endurance, particularly in the upper body. Nonetheless, these attributes in themselves are not valid grounds for exclusion from employment in physically demanding occupations. Selection standards based upon size or strength, irrespective of the job requirements, have resulted in the barring of capable women from physically demanding jobs, claims of gender bias, and costly litigations. To ensure all individuals are provided with equal access to employment, accurate characterization of the critical physical requirements of the job is paramount. This paper summarizes the existing research related to disparities between the sexes that contribute to sex differences in job performance in physically demanding occupations including physical and legal factors. Strategies for mitigating these differences in the setting of PES and the meeting of minimum employment standards are discussed. Where available, injury rates for women and men in physically demanding occupations are presented and the etiology considered. Finally, areas for further research are identified.

    Treatment for musculoskeletal disorders in primary care in Sweden is generally initiated with advice and medication. Second-line therapy is physiotherapy and/or injection and radiography; third-line therapy is referral to an orthopedist. Manual therapy is not routine. It is a challenge to identify patients who benefit from treatment by different specialists. The current referral strategy probably contributes to long waiting lists in orthopedic departments, which is costly and implies prolonged suffering for the patients. The aim of this health economic evaluation was to compare costs and outcomes from naprapathic manual therapy (NMT) with orthopedic standard care for common, low-prioritized, nonsurgical musculoskeletal disorders, after second-line treatment. Diagnose Related Groups were used to define the costs, and the SF-36 was encoded to evaluate the outcomes in cost per quality adjusted life years gained. Results from a 12 months' follow-up showed significantly larger improvement for the NMT than for orthopedic standard care, significantly lower mean cost per patient; 5427 SEK (*Price level 2009; 1 Euro=106,213 SEK; 1 US Dollar=76,457 SEK) (95% confidence interval, 3693-7161) compared to14298 SEK (95% confidence interval, 8322-20,274), and more gains in outcomes in cost per quality adjusted life years per patient (0.066 compared with 0.026). Thus the result is "dominant." It is plausible that improved outcomes and reasonable cost savings for low-prioritized nonsurgical outpatients would be attainable if NMT were available as an additional standard care option in orthopedic outpatient clinics.

    In order to further advance research and development on the Clinical Data Interchange Standards Consortium (CDISC) Operational Data Model (ODM) standard, the existing research must be well understood. This paper presents a methodological review of the ODM literature. Specifically, it develops a classification schema to categorize the ODM literature according to how the standard has been applied within the clinical research data lifecycle. This paper suggests areas for future research and development that address ODM's limitations and capitalize on its strengths to support new trends in clinical research informatics. A systematic scan of the following databases was performed: (1) ABI/Inform, (2) ACM Digital, (3) AIS eLibrary, (4) Europe Central PubMed, (5) Google Scholar, (5) IEEE Xplore, (7) PubMed, and (8) ScienceDirect. A Web of Science citation analysis was also performed. The search term used on all databases was "CDISC ODM." The two primary inclusion criteria were: (1) the research must examine the use of ODM as an information system solution component, or (2) the research must critically evaluate ODM against a stated solution usage scenario. Out of 2686 articles identified, 266 were included in a title level review, resulting in 183 articles. An abstract review followed, resulting in 121 remaining articles; and after a full text scan 69 articles met the inclusion criteria. As the demand for interoperability has increased, ODM has shown remarkable flexibility and has been extended to cover a broad range of data and metadata requirements that reach well beyond ODM's original use cases. This flexibility has yielded research literature that covers a diverse array of topic areas. A classification schema reflecting the use of ODM within the clinical research data lifecycle was created to provide a categorized and consolidated view of the ODM literature. The elements of the framework include: (1) EDC (Electronic Data Capture) and EHR (Electronic Health Record

  2. Hypertonic saline (HTS versus standard (isotonic fluid therapy for traumatic brain injuries: a systematic review

    Full Text Available Traumatic Brain Injury (TBI is one of the foremost causes of mortality secondary to trauma. Poorer outcomes are associated with secondary insults, after the initial brain injury occurred. The management goal of TBI is to prevent or minimise the effects of secondary brain injuries. The primary objective of this systematic review/meta-analysis was to assess the effects of Hypertonic Saline (HTS compared to Standard Fluid Therapy (SFT in the treatment and resuscitation of TBI patients. We searched CENTRAL, MEDLINE (from 1966, EBSCOhost, Scopus, ScienceDirect, Proquest Medical Library and EMBASE (from 1980 in May 2010 and updated searches in February 2011. Data were assessed and extracted by two independent authors. Risk ratios (RR with a 95% confidence interval (CI were used as the effect measure. The review included three RCTs (1184 participants of which two were of high to moderate quality (1005 participants. HTS was not found to be associated with a reduction in mortality (3 RCTs, 1184 participants, RR 0.91, 95%CI 0.76 to 1.09 and morbidity in TBI patients. No significant improvement in haemodynamical stability was found whereas insufficient data were available to indicate a reduction in the intracranial pressure (ICP. In the HTS group, cerebral perfusion pressure (CPP (MD 3.83 mmHg, 95%CI 1.08 to 6.57 and serum sodium level (MD 8 mEq/L, 95%CI 7.47 to 8.53 were higher. Existing studies show no indication that HTS, in comparison to SFT, reduces mortality or morbidity after the occurrence of TBI. Against this backdrop, some uncertainties still exist in terms of the use of different concentrations and volumes of HTS, the timing of administration as well as the benefit in specific injury profiles. As a result, formulating conclusive recommendations is complex.

    Head and neck squamous cell carcinoma (HNSCC) remains a challenging cancer to treat with overall 5-year survival on the order of 50-60%. Therefore, predictive biomarkers for this disease would be valuable to provide more effective and individualized therapeutic approaches for these patients. While prognostic biomarkers such as p16 expression correlate with outcome; to date, no predictive biomarkers have been clinically validated for HNSCC. We generated xenografts in immunocompromised mice from six established HNSCC cell lines and evaluated response to cisplatin, cetuximab, and radiation. Tissue microarrays were constructed from pre- and posttreatment tumor samples derived from each xenograft experiment. Quantitative immunohistochemistry was performed using a semiautomated imaging and analysis platform to determine the relative expression of five potential predictive biomarkers: epidermal growth factor receptor (EGFR), phospho-EGFR, phospho-Akt, phospho-ERK, and excision repair cross-complementation group 1 (ERCC1). Biomarker levels were compared between xenografts that were sensitive versus resistant to a specific therapy utilizing a two-sample t-test with equal standard deviations. Indeed the xenografts displayed heterogeneous responses to each treatment, and we linked a number of baseline biomarker levels to response. This included low ERCC1 being associated with cisplatin sensitivity, low phospho-Akt correlated with cetuximab sensitivity, and high total EGFR was related to radiation resistance. Overall, we developed a systematic approach to identifying predictive biomarkers and demonstrated several connections between biomarker levels and treatment response. Despite these promising initial results, this work requires additional preclinical validation, likely involving the use of patient-derived xenografts, prior to moving into the clinical realm for confirmation among patients with HNSCC.

Compared to other breast cancer subtypes, TNBC is more aggressive, has a higher prevalence in African-Americans, and more frequently affects younger patients. Currently, TNBC lacks clinically accepted targets for tailored therapy, warranting the need for candidate biomarkers. BiomarkerBase, an online platform used to find biomarkers reported in clinical trials, was utilized to screen all potential biomarkers for TNBC and select only the ones registered in completed TNBC trials through clinicaltrials.gov. The selected candidate biomarkers were classified as surrogate, prognostic, predictive, or pharmacodynamic (PD and organized by location in the blood, on the cell surface, in the cytoplasm, or in the nucleus. Blood biomarkers include vascular endothelial growth factor/vascular endothelial growth factor receptor and interleukin-8 (IL-­8; cell surface biomarkers include EGFR, insulin-like growth factor binding protein, c-Kit, c-Met, and PD-L1; cytoplasm biomarkers include PIK3CA, pAKT/S6/p4E-BP1, PTEN, ALDH1, and the PIK3CA/AKT/mTOR-related metabolites; and nucleus biomarkers include BRCA1, the glucocorticoid receptor, TP53, and Ki67. Candidate biomarkers were further organized into a “cellular protein network” that demonstrates potential connectivity. This review provides an inventory and reference point for promising biomarkers for breakthrough targeted therapies in TNBC. Keywords: anti-cancer directed pharmacotherapy, difficult

  5. Where current pharmacological therapies fall short in COPD: symptom control is not enough

    2007-09-01

    Full Text Available Chronic obstructive pulmonary disease (COPD is a common and progressive condition that is currently the fourth leading cause of death worldwide. There is now a large body of evidence indicating that both pulmonary and systemic inflammation are present in patients with stable COPD and may underlie both respiratory symptoms and common comorbidities of this disease. Smoking cessation and long-term oxygen therapy have been shown to change the course of COPD and recent results obtained with the combination of fluticasone and salmeterol have indicated that it could decrease mortality and slow the decline in lung function in patients with this disease. However, some pharmacological treatments can significantly improve dyspnoea, exercise tolerance, limitations in activity, rate of exacerbations and quality of life (e.g. long-acting bronchodilators and inhaled corticosteroids combined with a long-acting beta2-agonist. The ability of these agents to modify the rate of disease progression remains to be firmly established in large-scale, long-term trials. The concept of disease modification itself in COPD may need to be revisited and more precisely defined in terms of markers and clinical outcomes, including extrarespiratory manifestations: agents that durably affect symptoms, activities, exacerbations and quality of life should probably be considered as disease modifiers. It is also reasonable to suggest that early diagnosis and treatment of patients with COPD might be the first and potentially most important disease-modifying intervention. There is clearly a need for new therapies that directly target the specific inflammatory processes underlying chronic obstructive pulmonary disease and its pulmonary and extrapulmonary manifestations.

    Non-bismuth quadruple sequential therapy (SEQ) comprising a first induction phase with a dual regimen of amoxicillin and a proton pump inhibitor (PPI) for five days followed by a triple regimen phase with a PPI, clarithromycin and metronidazole for another five days, has been suggested as a new first-line treatment option to replace the standard triple therapy (STT) comprising a proton pump inhibitor (PPI), clarithromycin and amoxicillin, in which eradication proportions have declined to disappointing levels. To conduct a meta-analysis of randomised controlled trials (RCTs) comparing the efficacy of a SEQ regimen with STT for the eradication of H. pylori infection, and to compare the incidence of adverse effects associated with both STT and SEQ H. pylori eradication therapies. We conducted bibliographical searches in electronic databases, and handsearched abstracts from Congresses up to April 2015. We sought randomised controlled trials (RCTs) comparing 10-day SEQ and STT (of at least seven days) for the eradication of H. pylori. Participants were adults and children diagnosed as positive for H. pylori infection and naïve to H. pylori treatment. We used a pre-piloted, tabular summary to collect demographic and medical information of included study participants as well as therapeutic data and information related to the diagnosis and confirmatory tests.We evaluated the difference in intention-to-treat eradication between SEQ and STT regimens across studies, and assessed sources of the heterogeneity of this risk difference (RD) using subgroup analyses.We evaluated the quality of the evidence following Cochrane standards, and summarised it using GRADE methodology. We included 44 RCTs with a total of 12,284 participants (6042 in SEQ and 6242 in STT). The overall analysis showed that SEQ was significantly more effective than STT (82% vs 75% in the intention-to-treat analysis; RD 0.09, 95% confidence interval (CI) 0.06 to 0.11; P STT were greater in Europe (RD 0.16, 95

Aims: The objective of this paper is to highlight various parameters of DCP therapy and also, to report the effects of a few modifications in the regimen. Methods: An analysis of 123 patients treated with the DCP/DP regimen over a period of five years (1998 to 2002 is presented here. Seventeen patients who did not start/continue the treatment and three patients who died during the treatment have been excluded from the analysis. Twenty patients who had not yet started families were given only dexamethasone pulses (DPs while 103 patients received DCPs. Low dose (50 mg/day cyclophosphamide was used as in the standard regimen. The three modifications introduced into the regimen were: (1 an additional daily dose of oral betamethasone sufficient to control the disease activity during phase I, which was progressively tapered off completely as the patient recovered, (2 use of systemic antibiotics if the patient had skin lesions, and oral anti-candida drugs if the patient had oral ulcers until complete healing, and (3 insistence on thorough cleaning of the skin and scalp with a normal soap and shampoo, and proper maintenance of oral hygiene in spite of skin/mucosal lesions. The regimen consisted of DCP/DP repeated in exactly 28-day cycles, along with 50 mg cyclophosphamide per day, insistence on completing the treatment and avoiding irregular pulses in all patients. The number of DCPs/DPs during phase I varied in different patients depending upon the dose of betamethasone used and the rate of recovery, but phase II (nine DCPs/DPs in exactly 28-day cycles along with 50 mg cyclophosphamide per day and phase III (only 50 mg cyclophosphamide per day was fixed at nine months each. This was followed by posttreatment follow-up (phase IV. Results: At present, all the patients are in complete remission. The

    This article systematically reviews the research design and methodological characteristics of single-case experimental design (SCED) research published in peer-reviewed journals between 2000 and 2010. SCEDs provide researchers with a flexible and viable alternative to group designs with large sample sizes. However, methodological challenges have precluded widespread implementation and acceptance of the SCED as a viable complementary methodology to the predominant group design. This article includes a description of the research design, measurement, and analysis domains distinctive to the SCED; a discussion of the results within the framework of contemporary standards and guidelines in the field; and a presentation of updated benchmarks for key characteristics (e.g., baseline sampling, method of analysis), and overall, it provides researchers and reviewers with a resource for conducting and evaluating SCED research. The results of the systematic review of 409 studies suggest that recently published SCED research is largely in accordance with contemporary criteria for experimental quality. Analytic method emerged as an area of discord. Comparison of the findings of this review with historical estimates of the use of statistical analysis indicates an upward trend, but visual analysis remains the most common analytic method and also garners the most support amongst those entities providing SCED standards. Although consensus exists along key dimensions of single-case research design and researchers appear to be practicing within these parameters, there remains a need for further evaluation of assessment and sampling techniques and data analytic methods.

    To evaluate current perioperative antithrombotic management in neuroendovascular therapy in Japan, we analyzed perioperative anticoagulant and antiplatelet use in various procedures and examined their relationships with periprocedural adverse events. Patient's data from nationwide surveys administered by the Japanese Registry of Neuroendovascular Therapy (JR-NET) between January 2005 and December 2007 (JR-NET1) and January 2008 and December 2009 (JR-NET2) were retrospectively analyzed. Compared to JR-NET1, the frequency of perioperative antiplatelet therapy and dual or triple therapy were increased for either aneurysm coiling and percutaneous transluminal angioplasty or stenting in JR-NET2. Although ischemic complications were significantly decreased (4.2% vs. 2.1%, p antiplatelet therapy (preoperative: 5.3% vs. 9.2%, p therapy was performed more frequently and intensively in neuroendovascular therapy in Japan. While ischemic complications were decreased, hemorrhagic complications and severe adverse events were increased. These results suggest that intensive antithrombotic therapy has a potential risk of hemorrhagic complications for Japanese patients. PMID:24305029

    2015-01-01

    The management of advanced prostate cancer, specifically metastatic castrate-resistant prostate cancer (mCRPC), remains a therapeutic challenge. Sipuleucel-T (Provenge; APC8015) was approved by the FDA in 2010 for the treatment of asymptomatic or minimally symptomatic mCRPC patients, and it remains the only FDA-approved immunotherapy for prostate cancer of any indication to date. Given the continued need to improve therapeutics in patients with advanced prostate cancer, as well as recent enthusiasm for cancer immunotherapy, there is a wide range of ongoing trials evaluating combinations of sipuleucel-T with other therapeutics. Additional trials are aiming to expand the application of sipuleucel-T to prostate cancer patients beyond the mCRPC setting. Ongoing challenges include understanding the full mechanism of action of sipuleucel-T, optimizing the sequence of sipuleucel-T in relation to other therapies for mCRPC in clinical practice, and the identification of surrogate markers to predict survival benefit in clinical trials.

    In this perspective, we discuss the standardization of analytical techniques for pyrolysis bio-oils, including the current status of methods, and our opinions on future directions. First, the history of past standardization efforts is summarized, and both successful and unsuccessful validation of analytical techniques highlighted. The majority of analytical standardization studies to-date has tested only physical characterization techniques. Here, we present results from an international round robin on the validation of chemical characterization techniques for bio-oils. Techniques tested included acid number, carbonyl titrations using two different methods (one at room temperature and one at 80 degrees C), 31P NMR for determination of hydroxyl groups, and a quantitative gas chromatography-mass spectrometry (GC-MS) method. Both carbonyl titration and acid number methods have yielded acceptable inter-laboratory variabilities. 31P NMR produced acceptable results for aliphatic and phenolic hydroxyl groups, but not for carboxylic hydroxyl groups. As shown in previous round robins, GC-MS results were more variable. Reliable chemical characterization of bio-oils will enable upgrading research and allow for detailed comparisons of bio-oils produced at different facilities. Reliable analytics are also needed to enable an emerging bioenergy industry, as processing facilities often have different analytical needs and capabilities than research facilities. We feel that correlations in reliable characterizations of bio-oils will help strike a balance between research and industry, and will ultimately help to determine metrics for bio-oil quality. Finally, the standardization of additional analytical methods is needed, particularly for upgraded bio-oils.

    Full Text Available Meagan B Myers Division of Genetic and Molecular Toxicology, National Center for Toxicological Research, US Food and Drug Administration, Jefferson, AR, USA Abstract: Breast cancer is a multifaceted disease exhibiting both intertumoral and intratumoral heterogeneity as well as variable disease course. Over 2 decades of research has advanced the understanding of the molecular substructure of breast cancer, directing the development of new therapeutic strategies against these actionable targets. In vitro diagnostics, and specifically companion diagnostics, have been integral in the successful development and implementation of these targeted therapies, such as those directed against the human epidermal growth factor receptor 2. Lately, there has been a surge in the development, commercialization, and marketing of diagnostic assays to assist in breast cancer patient care. More recently, multigene signature assays, such as Oncotype DX, MammaPrint, and Prosigna, have been integrated in the clinical setting in order to tailor decisions on adjuvant endocrine and chemotherapy treatment. This review provides an overview of the current state of breast cancer management and the use of companion diagnostics to direct personalized approaches in the treatment of breast cancer.

    To evaluate the methods and major outcomes of transcranial direct current stimulation (tDCS) combined with virtual reality (VR) therapy in randomized controlled trials. A systematic review was performed following PRISMA guidelines using PubMed, PubMed Central, Web of Science and CAPES periodic databases, with no time restriction. The studies were screened for the following inclusion criteria: human subjects, combination of VR and tDCS methods, and randomized controlled study design. All potentially relevant articles were independently reviewed by two researchers, who reached a consensus on which articles met the inclusion criteria. The PEDro scale was used to evaluate the studies. Eleven studies were included, all of which utilized a variety of tDCS and VR application methods. The main outcomes were found to be beneficial in intervention groups of different populations, including improvements in body sway, gait, stroke recovery, pain management and vegetative reactions. The use of tDCS combined with VR showed positive results in both healthy and impaired patients. Future studies with larger sample sizes and homogeneous participants are required to confirm the benefits of tDCS and VR. Implications for Rehabilitation tDCS with VR intervention can be an alternative to traditional rehabilitation programs. tDCS with VR is a promising type of intervention with a variety of positive effects. Application of tDCS with VR is appropriated to both healthy and impaired patients. There is no consensus of tDCS with VR application.

    Inadequate surgical margins represent a high risk for adverse clinical outcome in breast-conserving therapy (BCT) for early-stage breast cancer. The majority of studies report positive resection margins in 20% to 40% of the patients who underwent BCT. This may result in an increased local recurrence (LR) rate or additional surgery and, consequently, adverse effects on cosmesis, psychological distress, and health costs. In the literature, various risk factors are reported to be associated with positive margin status after lumpectomy, which may allow the surgeon to distinguish those patients with a higher “a priori” risk for re-excision. However, most risk factors are related to tumor biology and patient characteristics, which cannot be modified as such. Therefore, efforts to reduce the number of positive margins should focus on optimizing the surgical procedure itself, because the surgeon lacks real time intraoperative information on the presence of positive resection margins during breast-conserving surgery. This review presents the status of pre- and intraoperative modalities currently used in BCT. Furthermore, innovative intraoperative approaches, such as positron emission tomography, radio-guided occult lesion localization, and near-infrared fluorescence optical imaging, are addressed, which have to prove their potential value in improving surgical outcome and reducing the need for re-excision in BCT.

    Atopic dermatitis (AD) is a complex, chronic inflammatory skin disorder affecting more than 10% of UK children and is a major cause of occupation-related disability. A subset of patients, particularly those with severe AD, are persistently colonised with Staphylococcus aureus (S. aureus) and exacerbation of disease is commonly associated with this bacterium by virtue of increased inflammation and allergic sensitisation, aggravated by skin barrier defects. Understanding the complex biology of S. aureus is an important factor when developing new drugs to combat infection. S. aureus generates exoproteins that enable invasion and dissemination within the host skin but can also damage the skin and activate the host immune system. Antibiotics are often used by dermatologists to aid clearance of S. aureus; however, these are becoming less effective and chronic usage discouraged with the emergence of multiple antibiotic-resistant strains. New ways to target S. aureus using monoclonal antibodies and vaccines are now being developed. This review will attempt to evaluate the key biology of S. aureus, current treatment of S. aureus infections in atopic dermatitis and recent advances in developing new anti-S. aureus therapies that have potential in severe AD.

    The PI3K-Akt pathway is a vital regulator of cell proliferation and survival.Alterations in the PIK3CA gene that lead to enhanced PI3K kinase activity have been reported in many human cancer types,including cancers of the colon,breast,brain,liver,stomach and lung.Deregulation of PI3K causes aberrant Akt activity.Therefore targeting this pathway could have implications for cancer treatment.The first generation PI3K-Akt inhibitors were proven to be highly effective with a low IC50,but later,they were shown to have toxic side effects and poor pharmacological properties and selectivity.Thus,these inhibitors were only effective in preclinical models.However,derivatives of these first generation inhibitors are much more selective and are quite effective in targeting the PI3K-Akt pathway,either alone or in combination.These second-generation inhibitors are essentially a specific chemical moiety that helps to form a strong hydrogen bond interaction with the PI3K/Akt molecule.The goal of this review is to delineate the current efforts that have been undertaken to inhibit the various components of the PI3K and Akt pathway in different types of cancer both in vitro and in vivo.Our focus here is on these novel therapies and their inhibitory effects that depend upon their chemical nature,as well as their development towards clinical trials.

    Ischemic stroke is caused by a thrombus that blocks an intracranial artery. Brain tissue beyond the blocked artery survives for a variable period of time because of blood and nutrients received through tiny vessels called collaterals. Imaging the brain and the vasculature that supplies it is therefore a vital first step in treating patients with acute ischemic stroke. In this review, we focus on current evidence for imaging selection of patients for endovascular therapy in the context of the recently positive clinical trials, such as Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands (MR CLEAN), Endovascular Treatment for Small Core and Anterior Circulation Proximal Occlusion With Emphasis on Minimizing Computed Tomography to Recanalization Times (ESCAPE), Solitaire With the Intention for Thrombectomy as Primary Endovascular Treatment (SWIFT PRIME), and Extending the Time for Thrombolysis in Emergency Neurological Deficits-Intra-Arterial (EXTEND-IA). We discuss evidence for and use of the various imaging paradigms available. We discuss how to set up quick and efficient imaging protocols for patient selection and address common concerns about the use of imaging, including time spent, contrast, radiation, and other advantages and disadvantages. Finally, we briefly comment on how imaging can integrate itself within various health systems of care in the future, thereby potentially improving patient outcomes further. © 2015 American Heart Association, Inc.

    Fibromyalgia (FM) is a chronic medical condition characterized by physical, psychiatric and psychological symptoms. Widespread pain, fatigue, sleep disturbances, heightened sensitivity, morning stiffness, decreased volition, depressed mood and a history of early abuse are frequently reported by patients with FM. Treatment of fibromyalgia is multidisciplinary, with an emphasis on active patient participation, medications, cognitive-behavioral therapy and physical modalities. No single medication has yet been found to sufficiently control all the symptoms of FM; currently available medication classes include antidepressants, nonsteroidal anti-inflammatory drugs, opioids, sedatives, muscle relaxants, analgesics, hypnotic agents and anticonvulsants. Hence, treatment for patients with FM, including pharmacological and non-pharmacological approaches, should be individualized based on each patient's clinical history, target symptoms and functional impairments. Although nonpharmacological modalities are also frequently used, recent research has focused on identifying more effective pharmacological treatments, particularly antidepressants and anticonvulsants. Furthermore, several new pharmacological agents have been now officially approved for the treatment of patients with FM. Thus, the purpose of this review is to help healthcare professionals make informed decisions about the appropriate use of a number of pharmacological treatments for patients with FM.

    Boron neutron capture therapy (BNCT) is based on the nuclear reaction that occurs when boron-10 is irradiated with low-energy thermal neutrons to yield alpha particles and recoiling lithium-7 nuclei. High-grade astrocytomas, glioblastoma multiforme, and metastatic brain tumors constitute a major group of neoplasms for which there is no effective treatment. There is growing interest in using BNCT in combination with surgery to treat patients with primary, and possibly metastatic brain tumors. For BNCT to be successful, a large number of 10B atoms must be localized on or preferably within neoplastic cells, and a sufficient number of thermal neutrons must reach and be absorbed by the 10B atoms to sustain a lethal 10B(n, alpha)7 Li reaction. Two major questions will be addressed in this review. First, how can a large number of 10B atoms be delivered selectively to cancer cells? Second, how can a high fluence of neutrons be delivered to the tumor? Two boron compounds currently are being used clinically, sodium borocaptate (BSH) and boronophenylalanine (BPA), and a number of new delivery agents are under investigation, including boronated porphyrins, nucleosides, amino acids, polyamines, monoclonal and bispecific antibodies, liposomes, and epidermal growth factor. These will be discussed, and potential problems associated with their use as boron delivery agents will be considered. Nuclear reactors, currently, are the only source of neutrons for BNCT, and the fission process within the core produces a mixture of lower-energy thermal and epithermal neutrons, fast or high (> 10,000 eV) energy neutrons, and gamma rays. Although thermal neutron beams have been used clinically in Japan to treat patients with brain tumors and cutaneous melanomas, epithermal neutron beams should be more useful because of their superior tissue-penetrating properties. Beam sources and characteristics will be discussed in the context of current and future BNCT trials. Finally, the past and present

    Oral and maxillofacial surgeons who perform orthognathic surgery face major changes in their practices, and these challenges will increase in the near future, because the extraordinary advances in technology applied to our profession are not only amazing but are becoming the standard of care as they promote improved outcomes for our patients. Orthognathic surgery is one of the favorite areas of practicing within the scope of practice of an oral and maxillofacial surgeon. Our own practice in orthognathic surgery has completed over 1,000 surgeries of this type. Success is directly related to the consistency and capability of the surgical-orthodontic team to achieve predictable, stable results, and our hypothesis is that a successful result is directly related to the way we take our records and perform diagnosis and treatment planning following basic general principles. Now that we have the opportunity to plan and treat 3-dimensional (3D) problems with 3D technology, we should enter into this new era with appropriate standards to ensure better results, instead of simply enjoying these new tools, which will clearly show not only us but everyone what we do when we perform orthognathic surgery. Appropriate principles need to be taken into account when implementing this new technology. In other words, new technology is welcome, but we do not have to reinvent the wheel. The purpose of this article is to review the current protocol that we use for orthognathic surgery and compare it with published protocols that incorporate new 3D and virtual technology. This report also describes our approach to this new technology.

    To review the current literature on the use of hyperbaric oxygen (HBO₂) therapy in the treatment of osteonecrosis of the femoral head (ONFH). We searched PubMed, Directory of Open Access Journals (DOAJ), EMBASE, Web of Science, Academic Search Complete, CINAHL and MEDLINE through April 2015. We hand-searched relevant textbooks, conference proceedings and the reference lists of review articles and clinical studies Randomized controlled trials (RCT) and observational studies (cohort study, case-control study, case series) that reported the outcome of patients who received HBO₂therapy for ONFH were included. Only English-language articles were included. Study quality was not used as an exclusion criterion. Two authors independently assessed trials for inclusion, extracted data and presented to other authors. Disagreements were resolved by consensus. We identified eight clinical studies; two randomized controlled trials (RCTs); one historically controlled study; and five case series. The majority of the studies were small-scale, heterogeneous and methodologically weak. In four of the studies HBO₂therapy was combined with other treatment modalities, making it impossible to draw firm conclusions on the specific effects of HBO₂therapy. Hip survivorship in studies wherein HBO₂therapy was used alone was 95.5% in Steinberg Stage I lesions, 89% in Steinberg Stage II lesions and 100% in Ficat Stage II lesions. There is a room for HBO₂therapy in the management ONFH. Further RCTs, however, are required to better elucidate the role of HBO₂therapy in the treatment of ONFH.

    Sensitization prevalence to moulds reached from less than 10% in the general population to more than 25% in atopic and/or asthmatic subjects. To diagnose IgE-mediated mould sensitization, skin prick test (SPT) and specific IgE (sIgE) measurement are recommended. However, concordance of SPT and sIgE results is often less than 50% and standardization of the extracts is required to achieve reliable test results. The aim of our study was to analyse mould SPT solutions (SPTs) with respect to quantity and quality of protein, antigen and human IgE-binding content as a prerequisite for further in vivo studies. Commercial SPTs of Alternaria alternata, Aspergillus fumigatus, Cladosporium herbarum and Penicillium chrysogenum from six manufacturers as well as two in-house extracts from Aspergillus versicolor were investigated. Protein-, antigen- and IgE-binding contents were quantified by Bradford assay, sandwich ELISA and IgE-ImmunoCAP-inhibition tests. Protein composition and IgE and IgG binding were analysed by SDS-PAGE and immunoblotting, respectively. Median protein concentrations were similar in all mould SPT extracts (90-110 μg/mL). In contrast, antigen contents and IgE-binding capacity showed a high variability with median antigen values from 4 to 118 μg/mL and IgE inhibition results between 30 to 95%. Whereas almost all SPTs of A. alternata and A. versicolor showed complete sIgE inhibition with mean values > 80%, only three extracts for A. fumigatus, two extracts for C. herbarum and none of the tested extracts for P. chrysogenum exceeded 50% sIgE reduction. Quantitative amounts of protein, antigenic and IgE-binding structures were not comparable with the quality of the corresponding protein or immunoblot pattern, with the exception of A. alternata SPTs. Commercially available mould SPT extracts showed high variability raising the question of comparability and reliability of SPT results. Possible consequences for diagnostic test outcome will be investigated

    Endoplasmic reticulum (ER)-resident α-glucosidases I and II sequentially trim the three terminal glucose moieties on N-linked glycans attached to nascent glycoproteins. These reactions are the first steps of N-linked glycan processing and are essential for proper folding and function of many glycoproteins. Because most viral envelope glycoproteins contain N-linked glycans, inhibition of ER α-glucosidases with derivatives of 1-deoxynojirimycin (DNJ) or castanospermine (CAST), two well-studied pharmacophores of α-glucosidase inhibitors, efficiently disrupts the morphogenesis of a broad spectrum of enveloped viruses. Moreover, both DNJ and CAST derivatives have been demonstrated to prevent the death of mice infected with several distinct flaviviruses and filoviruses and suppress the multiplication of several other species of viruses in infected animals. N-Butyl derivative of DNJ (NB-DNJ) and 6 O-bytanoyl prodrug of CAST (Bu-CAST) have been evaluated in human clinical trials for their antiviral activities against human immunodeficiency virus and hepatitis C virus, and there is an ongoing trial of treating dengue patients with Bu-CAST. This article summarizes the current status of ER α-glucosidase-targeted antiviral therapy and proposes strategies for development of more efficacious and specific ER α-glucosidase inhibitors as broad-spectrum, drug resistance-refractory antiviral therapeutics. These host function-targeted, broad-spectrum antiviral agents do not rely on time-consuming etiologic diagnosis, and should therefore be particularly promising in the management of viral hemorrhagic fever and respiratory tract viral infections, medical conditions that can be caused by many different enveloped RNA viruses, with a short window for medical intervention.

    To evaluate the types of cognitive services offered and the number of patients being served in community pharmacies, determine the number of pharmacies that plan to offer medication therapy management (MTM) services under the Medicare Part D prescription drug benefit, and assess whether current and expected practices will meet the potential needs of enrollees. Cross-sectional study. North Carolina in January 2005. 1,593 community pharmacy managers. Survey using a Web-based tool. Provision of cognitive services and number of patients for whom services are provided. A total of 262 (16%) pharmacy managers provided usable responses. Approximately 42% of respondents (n = 110) indicated that they provide some type of cognitive service. Comprehensive MTM services, or services consistent with the professionwide consensus definition, were provided by 31% of respondents (n = 81). Independent pharmacies were more likely to offer some type of service compared with chain pharmacies (58% versus 31%, respectively; P Pharmacy managers with a doctor of pharmacy degree were less likely than pharmacy managers with a bachelor's degree to offer services in their pharmacies (P = .02), and pharmacies with pharmacists on staff who had received certificate training were more likely to offer cognitive services (P = .03). Of all respondents, 28% (n = 73) indicated that they planned to offer MTM services under the Medicare Part D prescription drug benefit. Comparing these results with those of a 1999 survey of North Carolina pharmacists that used some of the same items, the percentage of community pharmacies that provide cognitive services has increased in the intervening years but remains low. Among the services being offered in 2005, most were focused on patient education and training, coordinating and integrating care, and medication regimen reviews. Implementation of MTM services under the Medicare Part D prescription drug benefit should hasten the development and offering of these

    Relapsing-remitting multiple sclerosis (RRMS), a CNS inflammatory demyelinating disease, is one of the most prevalent causes of chronic disability in young adults. Studies of the disease pathogenesis have identified multiple therapeutic targets. The number of approved disease modifying therapies has almost doubled within the past 5 years, which creates a challenge for medical professionals to stay abreast of their use in everyday practice. This manuscript provides an overview of available injectable, oral, and intravenous therapies for RRMS, and offers guidance in selecting an appropriate therapy. Focus is on the recently approved and emerging monoclonal antibody therapies, because they offer more selective and superior therapeutic efficacy compared with injectable and oral disease modifying therapies. We discuss the outlook for monoclonal antibodies and their role in RRMS treatment in the future.

    The current ICARTT file format standards were developed for the purpose of fulfilling the data management needs for the International Consortium for Atmospheric Research on Transport and Transformation (ICARTT) campaign in 2004. The goal of the ICARTT file format was to establish a common and simple to use data file format to promote data exchange and collaboration among science teams with similar science objectives. ICARTT has been the NASA standard since 2010, and is widely used by NOAA, NSF, and international partners (DLR, FAAM). Despite its level of acceptance, there are a number of issues with the current ICARTT format, especially concerning the machine readability. To enhance usability, the ICARTT Refresh Earth Science Data Systems Working Group (ESDSWG) was established to enable a platform for atmospheric science data producers, users (e.g. modelers) and data managers to collaborate on developing criteria for this file format. Ultimately, this is a cross agency effort to improve and aggregate the metadata records being produced. After conducting a survey to identify deficiencies in the current format, we determined which are considered most important to the various communities. Numerous recommendations were made to improve upon the file format while maintaining backward compatibility. The recommendations made to date and their advantages and limitations will be discussed.

    The aim of pharmacological therapy for asthma is to improve symptoms and lung function and minimize the risk of asthma attacks. The intensity of treatment is based on the level of asthma control and the potential risk of future deterioration. In the British asthma guidelines, treatments are divided into steps 1 to 5, with each step signifying a need for an increase in therapy in response to symptoms or to prevent exacerbations. Treatments comprise of inhaled or systemic medications. Inhaled therapy includes short-acting and long-acting medication to improve symptoms and inhaled corticosteroids that reduce airway inflammation. Systemic treatments include medications that act on specific biological pathways, such as the leukotriene or immunoglobulin E pathways, or systemic corticosteroids. In choosing a particular therapy, treatment benefits are balanced by the potential risks of medication-related adverse effects. This review will provide a practical guide to the key pharmacological therapies for adult asthma at steps 1 to 5 based on British guidelines and consider future options for new treatments.

    Standard postharvest unit operations that rely on copious water contact, such as fruit unloading and washing, approach the criteria for a true critical control point in fresh tomato production. Performance data for approved sanitizers that reflect commercial systems are needed to set standards for audit compliance. This study was conducted to evaluate the efficacy of chlorine dioxide (ClO(2)) for water disinfection as an objective assessment of recent industry-adopted standards for dump tank and flume management in fresh tomato packing operations. On-site assessments were conducted during eight temporally distinct shifts in two Florida packinghouses and one California packinghouse. Microbiological analyses of incoming and washed fruit and dump and flume system water were evaluated. Water temperature, pH, turbidity, conductivity, and oxidation-reduction potential (ORP) were monitored. Reduction in populations of mesophilic and coliform bacteria on fruit was not significant, and populations were significantly higher (P dump tanks but consistently below the detection limit in flumes. Turbidity and conductivity increased with loads of incoming tomatoes. Water temperature varied during daily operations, but pH and ORP mostly remained constant. The industry standard positive temperature differential of 5.5°C between water and fruit pulp was not maintained in tanks during the full daily operation. ORP values were significantly higher in the flume than in the dump tank. A positive correlation was found between ORP and temperature, and negative correlations were found between ORP and turbidity, total mesophilic bacteria, and coliforms. This study provides in-plant data indicating that ClO(2) can be an effective sanitizer in flume and spray-wash systems, but current operational limitations restrict its performance in dump tanks. Under current conditions, ClO(2) alone is unlikely to allow the fresh tomato industry to meet its microbiological quality goals under typical

    Full Text Available Background: Anterior cervical discectomy and fusion (ACDF is a commonly performed surgical procedure. However, there is substantial debate regarding the role of physical therapy following this procedure. Therefore, we sought to determine current physical therapy practice following ACDF surgery, as well as determine physical therapists beliefs regarding rehabilitation following ACDF. Methods: One hundred and eighty three licensed Physical Therapists were invited to participate in a descriptive internet based survey; a total of 53 (29% completed the survey. Physical Therapists were assessed for their current practice, asked to rate the clinical usefulness of various treatment modalities, and indicate their recommendations regarding post-operative physical therapy for subjects following anterior discectomy and fusion. Results were then assessed for frequency distributions, with chi-square analysis for association between demographic data and practice recommendations. Results: The results indicate that Physical Therapists believe patients achieve superior outcomes with the inclusion of post-operative physical therapy, with a low risk of harm. Specific treatments indicated as most useful included endurance exercise (60.4%, isometric strengthening (56.6%, and stretching (45.3%. Other treatment options are discussed in detail. Conclusion: Physical Therapists identified specific activities that they felt were most appropriate for rehabilitation following ACDF surgery. These findings may help to direct both appropriate therapy prescription following ACDF, as well as future research.

    Full Text Available Cian M McCrudden, Helen O McCarthySchool of Pharmacy, Queen’s University Belfast, Belfast, UKAbstract: Breast cancer is characterized by a series of genetic mutations and is therefore ideally placed for gene therapy intervention. The aim of gene therapy is to deliver a nucleic acid-based drug to either correct or destroy the cells harboring the genetic aberration. More recently, cancer gene therapy has evolved to also encompass delivery of RNA interference technologies, as well as cancer DNA vaccines. However, the bottleneck in creating such nucleic acid pharmaceuticals lies in the delivery. Deliverability of DNA is limited as it is prone to circulating nucleases; therefore, numerous strategies have been employed to aid with biological transport. This review will discuss some of the viral and nonviral approaches to breast cancer gene therapy, and present the findings of clinical trials of these therapies in breast cancer patients. Also detailed are some of the most recent developments in nonviral approaches to targeting in breast cancer gene therapy, including transcriptional control, and the development of recombinant, multifunctional bio-inspired systems. Lastly, DNA vaccines for breast cancer are documented, with comment on requirements for successful pharmaceutical product development.Keywords: breast cancer, gene therapy, nonviral, clinical trial

    The aim of this investigation was to describe the effects of standardization and central control of the processes involved in postoperative pain management from patient and employee perspectives. Patients (n = 282/307) and respective hospital staff (n = 149/119) evaluated the processes, the quality of postoperative pain management and result parameters 3 months before and 12 months after the introduction of standardization of the postoperative pain therapy process using a set of standardized questionnaires. Pain level and the waiting period for an analgesic partially decreased and a higher subjective effectiveness of medication was achieved in patients after the standardization. Patients felt that the pain was taken more seriously and contacted the staff for additional medication more frequently. From an employee viewpoint the quality of care and individual competence and ability to treat pain increased after the introduction of standardization. Pain assessment was improved and employees rated their knowledge and education level as higher than before the intervention. Patients with pre-existing chronic pain and patients with special regional therapy benefited only partially after the introduction and an increase in pain intensity was even observed. The quality of care was improved by standardization of the postoperative pain management. The legal and practical ability of the nursing stuff to administer pain medication within well-defined margins reduced the dependence on the ward doctor and at the same time patient pain levels. Patients received analgesics more quickly and experienced increased effectiveness. These results should be an incentive to reconsider the importance of the organization of postoperative pain management, because the quality of care with all potential medical and economic advantages, can be easily optimized by such simple mechanisms. They also show that the quality assessment of acute pain and the selection of appropriate indicators

    Upper limb (UL) impairment is the most common disabling deficit following a stroke. Previous studies have suggested that transcranial direct current stimulation (tDCS) enhances the effect of conventional therapies. This pilot double-blind randomized control trial aimed to determine whether or not tDCS, combined with Wii virtual reality therapy (VRT), would be superior to Wii therapy alone in improving upper limb function and quality of life in chronic stroke individuals. Twenty participants were randomly assigned either to an experimental group that received VRT and tDCS, or a control group that received VRT and sham tDCS. The therapy was delivered over 15 sessions with 13 minutes of active or sham anodal tDCS, and one hour of virtual reality therapy. The outcomes included were determined using the Fugl-Meyer scale, the Wolf motor function test, the modified Ashworth scale (MAS), grip strength, and the stroke specific quality of life scale (SSQOL). Minimal clinically important differences (MCID) were observed when assessing outcome data. Both groups demonstrated gains in all evaluated areas, except for the SSQOL-UL domain. Differences between groups were only observed in wrist spasticity levels in the experimental group, where more than 50% of the participants achieved the MCID. These findings support that tDCS, combined with VRT therapy, should be investigated and clarified further.

    Introduction Helicobacter pylori colonization is present in half of the world’s population and can lead to numerous gastrointestinal diseases if left untreated, including peptic ulcer disease and gastric cancer. Although concurrent triple therapy remains the recommended treatment regimen for H. pylori eradication, its success rate and efficacy have been declining. Recent studies have shown that the addition of probiotics can significantly increase eradication rates by up to 50%. This meta-analysis examines the impact of probiotic supplementation on the efficacy of standard triple therapy in eradicating H. pylori. Methods A comprehensive literature search was conducted using PubMed, Cochrane Central Registry of Controlled Trials, and Google Scholar (time of inception to 2016) to identify all published randomized control trials (RCTs) assessing the use of probiotics in addition to triple therapy for the treatment of H. pylori. Searches were conducted using the keywords “probiotics”, “triple therapy”, and “Helicobacter pylori”. RCTs comparing the use of probiotics and standard triple therapy with standard triple therapy alone for any duration in patients of any age diagnosed with H. pylori infection were included. H. pylori eradication rates (detected using urea breath test or stool antigen) were analyzed as-per-protocol (APP) and intention-to-treat (ITT). Results A total of 30 RCTs involving 4,302 patients APP and 4,515 patients ITT were analyzed. The addition of probiotics significantly increased eradication rates by 12.2% (relative risk [RR] =1.122; 95% confidence interval [CI], 1.091–1.153; PProbiotics were beneficial among children and adults, as well as Asians and non-Asians. No significant difference was observed in efficacy between the various types of probiotics. The risk of diarrhea, nausea, vomiting, and epigastric pain was also reduced. Conclusion The addition of probiotics is associated with improved H. pylori eradication rates in both

    Severe asthma in the elderly places a high burden on affected individuals and society. Emerging therapies target specific phenotypes of the asthma disease spectrum, and can be beneficial for older asthmatics, albeit their response might be altered due to age-related characteristics. Paradoxically, these characteristics are often ground for exclusion from clinical trials. The question thus arises how the senior asthmatic population can successfully enter the era of targeted therapy. Therefore, we highlight characteristics of this population relevant to effective treatment, and review the evidence for targeted therapy in elderly patients. For targeted therapy it is important to account for aging, as this affects the distribution of phenotypes (e.g. late-onset asthma, non-eosinophilic asthma) and may alter biomarkers and drug metabolism. Elderly asthmatics suffer from age-related comorbidities and subsequent polypharmacy. A systematic search into targeted asthma therapy yielded no randomized clinical trials dedicated to older asthmatics. Post hoc analyses of the anti-immunoglobulin E agent omalizumab indicate similar efficacy in both younger and older adults. Conference abstracts on anti-interleukin-5 and anti-interleukin-13 therapy suggest even more pronounced effects of targeted treatments in late-onset disease and in asthmatic patients 65 years or older, but full reports are lacking. For non-eosinophilic asthma in the elderly, there is not yet high-level evidence for targeted therapy, but macrolides may offer a viable option. In conclusion, there is a gap in knowledge regarding the effect of older age on the safety and efficacy of targeted asthma therapy. Further investigations in the elderly are needed, with special emphasis on both late-onset asthma and therapeutics for non-eosinophilic asthma.

    A 49 y/o female under went 48 hyperbaric oxygen (HBO2) treatments at 2.5 ATA (atmospheres absolute) (253 kPa) for 90 minutes for chronic refractory osteomyelitis of the sacrum and recurrent failure of a sacral myocutaneous flap. Prior to HBO2 therapy, formal ophthalmic exams revealed myopia but no evidence of cataract formation. Eight weeks following the completion of HBO2 therapy, on repeat ophthalmic exam, the patient was discovered to have worsening myopia. Changes of the crystalline lens, consistent with nuclear cataract development, were identified in each eye. Other common causes of cataract formation including diabetes, corticosteroid use, and excessive exposure to ultraviolet light, were excluded. While transient visual changes are known to occur during HBO2 therapy, cataract formation has only rarely been reported and only after prolonged courses of treatment (150 or more treatments). This case identifies the need to further investigate the ocular effects of HBO2 therapy, especially with regard to cataract development and progression.

    Following the Second World War, the Food and Agriculture Organization (FAO) and the World Health Organization (WHO) teamed up to construct an International Codex Alimentarius (or 'food code') which emerged in 1963. The Codex Committee on Food Hygiene (CCFH) was charged with the task of developing microbial hygiene standards, although it found itself embroiled in debate with the WHO over the nature these standards should take. The WHO was increasingly relying upon the input of biometricians and especially the International Commission on Microbial Specifications for Foods (ICMSF) which had developed statistical sampling plans for determining the microbial counts in the final end products. The CCFH, however, was initially more focused on a qualitative approach which looked at the entire food production system and developed codes of practice as well as more descriptive end-product specifications which the WHO argued were 'not scientifically correct'. Drawing upon historical archival material (correspondence and reports) from the WHO and FAO, this article examines this debate over microbial hygiene standards and suggests that there are many lessons from history which could shed light upon current debates and efforts in international food safety management systems and approaches.

    In 2008 the UN General Assembly adopted resolution 62/217, endorsing the space debris mitigation guidelines (SDMG) of the UN Committee on the Peaceful Uses of Outer Space (UNCOPUOS). These guidelines contain recommendations for satellite operators to implement measures for various mission phases in order to reduce the further accumulation of space debris in space and especially within the protected regions. These are defined within the SDMG as being the LEO region (up to 2,000 km altitude) and the GEO region (∼200 km in altitude around the GEO altitude and ∼15 degrees latitude). In the first version of ESA's DRAMA tool suite, OSCAR (Orbital SpaceCraft Active Removal) was designed as a tool to allow users the analysis of different disposal stragies for spacecraft in the LEO and GEO region. The upgrade of the ESA DRAMA tool suite by TUBS and DEIMOS under ESA/ESOC contract included the development of a renewed version of the existing OSCAR tool, allowing in its current version the consideration of different future solar and geomagnetic activity scenarios and besides the already known disposal systems (chemical and electric propulsion, as well as electrodynamic tether) the analysis of the orbital evolution using drag augmentation devices. One of the primary goals was to implement techniques recommended by current standards. The recommendations from the SDMG were used for the definition of the critical regions as well as compliance criteria, the user may check his disposal strategy against. For satellites operating in GEO, the ISO 26872:2010 (Space Systems - Disposal of satellites operating at geosynchronous altitude) standard was accounted for. For the generation of future solar and geomagnetic activity, the standards ISO 27852:2011 (Space Systems -Estimation of orbit lifetime) and the ECSS-E-ST-10-04C (Space engineering - Space environment) have been considered and recommended modeling approaches were implemented. In this paper, the OSCAR tool is presented, giving

    Compensatory and restorative treatments have been developed to improve visual field defects after stroke. However, no controlled trials have compared these interventions with standard occupational therapy (OT). A total of 45 stroke participants with visual field defect admitted for inpatient rehabilitation were randomized to restorative computerized training (RT) using computer-based stimulation of border areas of their visual field defects or to a computer-based compensatory therapy (CT) teaching a visual search strategy. OT, in which different compensation strategies were used to train for activities of daily living, served as standard treatment for the active control group. Each treatment group received 15 single sessions of 30 minutes distributed over 3 weeks. The primary outcome measures were visual field expansion for RT, visual search performance for CT, and reading performance for both treatments. Visual conjunction search, alertness, and the Barthel Index were secondary outcomes. Compared with OT, CT resulted in a better visual search performance, and RT did not result in a larger expansion of the visual field. Intragroup pre-post comparisons demonstrated that CT improved all defined outcome parameters and RT several, whereas OT only improved one. CT improved functional deficits after visual field loss compared with standard OT and may be the intervention of choice during inpatient rehabilitation. A larger trial that includes lesion location in the analysis is recommended.

  2. An “Off-the-Shelf” System for Intraprocedural Electrical Current Evaluation and Monitoring of Irreversible Electroporation Therapy

    IntroductionIrreversible electroporation (IRE) ablation uses a series of brief electric pulses to create nanoscale defects in cell membranes, killing the cells. It has shown promise in numerous soft-tissue tumor applications. Larger voltages between electrodes will increase ablation volume, but exceeding electrical limits may risk damage to the patient, cause ineffective therapy delivery, or require generator restart. Monitoring electrical current for these conditions in real-time enables managing these risks. This capacity is not presently available in clinical IRE generators.MethodsWe describe a system using a Tektronix TCP305 AC/DC Current Probe connected to a TCPA300 AC/DC Current Probe Amplifier, which is read on a computer using a Protek DSO-2090 USB computer-interfacing oscilloscope. Accuracy of the system was tested with a resistor circuit and by comparing measured currents with final outputs from the NanoKnife clinical electroporation pulse generator.ResultsAccuracy of measured currents was 1.64 ± 2.4 % relative to calculations for the resistor circuit and averaged 0.371 ± 0.977 % deviation from the NanoKnife. During clinical pulse delivery, the system offers real-time evaluation of IRE procedure progress and enables a number of methods for identifying approaching issues from electrical behavior of therapy delivery, facilitating protocol changes before encountering therapy delivery issues.ConclusionsThis system can monitor electrical currents in real-time without altering the electric pulses or modifying the pulse generator. This facilitates delivering electric pulse protocols that remain within the optimal range of electrical currents—sufficient strength for clinically relevant ablation volumes, without the risk of exceeding safe electric currents or causing inadequate ablation.

    Purpose: Non-occlusive mesenteric ischemia (NOMI) is a life threatening disease. Therapy and prognosis depend upon the length of time elapsed between primary clinical manifestation and the time of definitive diagnosis and treatment. Materials and Methods: NOMI was diagnosed by intraarterial selective angiography in four patients. After a bolus administration of 20 g Alprostadil (Prostavasin trademark) into the superior mesenteric artery, intraarterial perfusion was continued with 60 {mu}g Alprostadil/day via the catheter for three days. Results: The mesenteric ischemia resolved in all patients. One patient recovered completely. Three patients recovered from mesenteric ischemia, but died subsequently due to complications of their primary diseases. Conclusion: When NOMI without perforation or necrosis of the bowel wall is suspected clinically, immediate intraarterial angiography is the diagnostic method of choice. If NOMI is confirmed, the appropriate treatment is the intraarterial application of potent vasodilators for several days. The diagnostic work-up in suspected NOMI and the impact of different radiological examinations are explained. The literature is reviewed. (orig.)

    The field of pediatric neurorehabilitation has rapidly evolved with the introduction of technological advancements over recent years. Rehabilitation robotics and computer-assisted systems can complement conventional physiotherapeutics or occupational therapies. These systems appear promising, especially in children, where exciting and challenging virtual reality scenarios could increase motivation to train intensely in a playful therapeutic environment. Despite promising experience and a large acceptance by the patients and parents, so far, only a few therapy systems have been evaluated in children, and well-designed randomized controlled studies in this field are still lacking. This narrative review aims to provide an overview about the to-date robot-assisted and computer-based therapies and the current level of evidence and to share the authors experience about the clinical implication of these new technologies available for children with cerebral palsy.

    2015-05-01

    This review considers the role of physical therapies in osteoarthritis management, highlighting key findings from systematic reviews and randomized controlled trials published in the last 2 years. Three new trials question the role of manual therapy for hip and knee osteoarthritis. No between-group differences in outcome were detected between a multimodal programme including manual therapy and home exercise, and placebo in one trial; a second trial found no benefit of adding manual therapy to an exercise programme, while a third trial reported marginal benefits over usual care that were of doubtful importance. Recent trials have also found no or uncertain clinical benefits of transcutaneous electrical nerve stimulation (TENS) or acupuncture, or of valgus braces or lateral wedge insoles for pain and function in knee osteoarthritis. Available evidence suggests a small to moderate effect of exercise in comparison with not exercising for hip or knee osteoarthritis, although optimum exercise prescription and dosage are unclear. One trial also observed a delay in joint replacement in people with hip osteoarthritis. Two trials have reported conflicting findings about the effects of exercise for hand osteoarthritis. Other than exercise, recent data suggest that the role of physical therapies in the treatment of osteoarthritis appears limited.

    Pulmonary infections involving Pseudomonas aeruginosa are among the leading causes of the deterioration of the respiratory status of cystic fibrosis (CF) patients. The emergence of multidrug-resistant strains in such populations, favored by iterative antibiotic cures, has led to the urgent need for new therapies. Among them, bacteriophage-based therapies deserve a focus. One century of empiric use in the ex-USSR countries suggests that bacteriophages may have beneficial effects against a large range of bacterial infections. Interest in bacteriophages has recently renewed in Western countries, and the in vitro data available suggest that bacteriophage-based therapy may be of significant interest for the treatment of pulmonary infections in CF patients. Although the clinical data concerning this specific population are relatively scarce, the beginning of the first large randomized study evaluating bacteriophage-based therapy in burn infections suggests that the time has come to assess the effectiveness of this new therapy in CF P. aeruginosa pneumonia. Consequently, the aim of this review is, after a brief history, to summarize the evidence concerning bacteriophage efficacy against P. aeruginosa and, more specifically, the in vitro studies, animal models, and clinical trials targeting CF.

    Treatment with first generation protease inhibitors (PIs) is a milestone in the history of HCV therapy. Triple therapy with boceprevir (BOC) improves sustained virological response (SVR) by 30% in treatment naïve genotype 1 patients and by 50-60% in relapsers, 40-45% in partial responders and 25% in null responders compared with the Pegylated Interferon (PEG-IFN) and ribavirin regimen. To optimize BOC treatment, screening and access to treatment must be improved in genotype 1 patients. To select the ideal candidate for immediate treatment with triple therapy, an individual risk/benefit ratio must be assessed. Recent data have shown that patients with compensated cirrhosis and more advanced disease may also benefit from this regimen. Moreover, in HCV patients with extrahepatic manifestations, patients with HCV recurrence after liver transplantation and HIV-HCV co-infected patients, immediate treatment with triple therapy should be discussed. There is growing evidence that triple therapy with BOC is cost-effective in genotype 1 patients. Finally, the treatment design of BOC must be optimized in relation to baseline characteristics, so that optimal stopping rules can be followed, Drug-drug interactions (DDIs) can be prevented and AEs can be accurately prevented and managed. © 2013 John Wiley & Sons A/S.

    Patients treated with oral anticoagulant therapy (OAT) represent an issue to the dentist, as an increasing number of people are using anticoagulant drugs for cardiovascular disease. The choice of an eventual suspension or continuation of anticoagulant therapy is important when considering an efficient management of the patient. Patients in anticoagulant therapy and requiring dental procedures sometimes represent therapeutic concerns especially concerning the suspension of the anticoagulant treatment. At the moment there is no consensus among international experts of a possible discontinuation of therapy before invasive dental procedures. In this paper, the authors try to focus on this topic through a critical review of the literature. Most of the studies suggest the continuation of the anticoagulant treatment with heparin before invasive oral surgical interventions. Based on the data of the literature, two rules must be adopted in clinical practice: 1) maintenance of anticoagulation related to the international normalized ratio (INR); 2) local application of antifibrinolytic agents to ensure a proper hemostatic process. Given the widespread use of anticoagulant drugs in cardiovascular disease, dentists must often face the problem of the therapy and, since there is no consensus on the management of these patients, the authors propose, after a thorough critical review of the literature, the implementation of a multiphase protocol of surgical approach to be implemented with safety in daily clinical practice.

However, given the inevitable cohort heterogeneity in salvage therapy, response to treatment and overall prognoses tend to vary widely, making meaningful conclusions about treatment efficacy difficult to derive. Despite the hurdles in current research, progress is underway toward more targeted therapeutic approaches. Several new drugs with novel mechanism of action and less toxic profile have been developed in the past decade, with the potential for use as single agents or in synergy with other treatment modalities in MM therapy. As our discovery of these emerging therapies progresses, so too does our need to reshape our knowledge on knowing how to apply them. This review highlights some of the recent landmark changes in MM management with specific emphasis on salvage drugs available for relapsed and refractory MM and also discusses some of the upcoming cutting-edge therapies that are currently in various stages of clinical development.

    Full Text Available Lung cancer is the leading cancer cause of death in the United States. Radiotherapy is an essential component of the definitive treatment of early-stage and locally-advanced lung cancer, and the palliative treatment of metastatic lung cancer. Proton beam therapy (PBT, through its characteristic Bragg peak, has the potential to decrease the toxicity of radiotherapy, and, subsequently improve the therapeutic ratio. Herein, we provide a primer on the physics of proton beam therapy for lung cancer, present the existing data in early-stage and locally-advanced non-small cell lung cancer (NSCLC, as well as in special situations such as re-irradiation and post-operative radiation therapy. We then present the technical challenges, such as anatomic changes and motion management, and future directions for PBT in lung cancer, including pencil beam scanning.

    The fluoroquinolone moxifloxacin has potent activity against Mycobacterium tuberculosis and has been recommended by the guidelines for the treatment of pulmonary tuberculosis (TB). Monotherapy is not recommended by the guidelines and only a few studies have evaluated the efficacy and safety of moxifloxacin plus standard first-line therapy in treating TB. The purpose of this meta-analysis was to further investigate the efficacy and safety of moxifloxacin plus standard therapy compared with standard therapy alone in treating patients with pulmonary TB. Medline, Cochrane, EMBASE and Google Scholar (until February 12, 2015) were searched for studies that evaluated the clinical efficacy and tolerability of moxifloxacin in the treatment of pulmonary TB. Rate of culture conversion and serious adverse events (SAEs) were assessed. Risk of bias and sensitivity analysis, using the leave-one-out approach, was used to assess the robustness of the findings. Six studies were included in the meta-analysis which covered 2056 patients with pulmonary TB. For all included studies, the drug regimens at least contained rifampicin and pyrazinamide and the length of treatment was at least eight weeks. The odds ratio (OR) for the negative culture rate for moxifloxacin plus first-line medications compared first-line medications alone (the control group) was 1.60 with 95% CI in 0.93-2.74 (P = 0.089), indicating the moxifloxacin plus first-line medications had no significantly greater rate of culture conversion compared with first-line medication alone. The odds ratio of SAEs for moxifloxacin plus first-line medications compared with first-line medications alone found no difference in rate of SAEs between treatment groups (OR = 0.94, P = 0.862). In conclusion, our meta-analysis suggests that there was a trend for the addition of moxifloxacin to standard first-line therapy for non-drug resistant TB resulted to increase the rate of culture conversion but this effect requires confirmation

    Spastic cerebral palsy (CP) is the one of most common neurological disorders occurring due to damage to the immature brain or any other brain lesion at the time of birth. To aid in making the life of the CP patient meaningful, several interventions such as medical, surgical and rehabilitation have been employed to date. Besides these, recently repetitive Transcranial magnetic stimulation (r-TMS) is a new found approach which is being employed for treating various neurological and psychological conditions. The aim of this study was to observe the effects of r-TMS on muscle spasticity in CP patients by stimulating the motor cortex area of the brain, which is responsible for muscle movements. In this study, 20 subjects diagnosed with CP were recruited and 10 each were placed in two groups, namely the research group (RG) (mean age, height and weight were 7.99 (SD = 4.66) years, 116.7 (SD = 23.57) cm and 21.40 (SD = 10.95) kg, respectively) and the control group (CG) (mean age, height and weight were 8.41 (SD = 4.32) years, 107.9 (SD = 26.33) cm, 21.40 (SD = 12.63) kg, respectively). r-TMS frequencies of 5 Hz and 10 Hz were administered for 15 min daily to patients in RG followed by standard therapy (ST) of 1 h duration daily for 20 days. Moreover, the patients in the control group (CG) were given only standard therapy (ST) of 1 h duration for 20 days. Modified Ashworth Scale (MAS) was used as an outcome measure to determine the level of muscle spasticity. A pre- assessment of MAS score was performed on both RG and CG to determine the level of spasticity prior to starting therapy; and similarly post-assessment after 20 days was done to observe the changes post-therapy. Statistical analysis of pre vs post MAS scores showed that few muscles showed reduction in muscle tightness after administering only ST in the CG. On the contrary, the RG that underwent r-TMS therapy combined with ST showed a significant decrease (p < 0.05) in muscle tightness for all the

    There continues to be controversy over whether operative delay is necessary for patients on antiplatelet therapy, particularly for elderly patients with hip fractures. This study sought to assess current clinical practices of orthopedic surgeons regarding perioperative management of these patients. A 12-question, Web-based survey was distributed to orthopedic surgeons via e-mail. Questions regarding timing of surgery assumed patients were on antiplatelet therapy and assessed attitudes toward emergent and nonemergent orthopedic cases as well as operative delay for specific closed fracture types. Responses were compared using unpaired, 2-tailed Student t tests for continuous variables and Pearson chi-square tests with odds ratios (ORs) and 95% confidence intervals (CIs) for categorical variables. Statistical significance was defined as a P value antiplatelet therapy with closed hip fractures did not require operative delay. Surgeons who opted for surgical delay in hip fractures were more likely to delay surgery in other lower extremity fracture types (OR = 16.4, 95% CI 4.48-60.61, P antiplatelet therapy. Over a quarter of surgeons continue to opt for surgical delay in patients with hip fracture. This survey highlights the need to formulate and better disseminate practice management guidelines for patients with fracture on antiplatelet therapy, particularly given the aging population in the United States.

    Under the condition of knowledge economy, the acu-moxibustion standardization definitely involves intellectual property rights. Then, what is the relationship between the standardization and the intellectual property rights of acu-moxibustion? The authors of the present paper hold that it is not only exclusive, but also syncretic. If their relationship cannot be handled properly, their own respective development will be affected adversely. Therefore, a proper handling of the relationship between the two is of great practical significance. The present paper makes a comprehensive analysis about their interaction (mutual promotion and mutual inhibition), similarities (systemic composition, dynamic implementation course, standardization-rated order and ultimate targets) and differences (in properties, working components, secret requirement, effectiveness-time limitation, usage cost, etc).

    Nicorandil, an adenosine triphosphate-sensitive potassium channel opener, improves cardiac sympathetic nerve activity (CSNA) in ischemic heart disease or chronic heart failure. However, its effects on CSNA and myocyte dysfunction in acute heart failure (AHF) remain unclear. We investigated the effects of adding intravenous nicorandil to standard therapy on CSNA and myocyte dysfunction in AHF. We selected 70 patients with mild to moderate nonischemic AHF who were treated with standard conventional therapy soon after admission. Thirty-five patients were assigned to additionally receive intravenous nicorandil (4-12 mg/h; group A), whereas the remaining patients continued their current drug regimen (group B). Delayed total defect score (TDS), delayed heart to mediastinum count (H/M) ratio, and washout rate (WR) were determined by {sup 123}I-metaiodobenzylguanidine (MIBG) scintigraphy within 3 days of admission and 4 weeks later. High sensitivity troponin T (hs-TnT) level was also measured at the same time points. After treatment, MIBG scintigraphic parameters significantly improved in both groups. However, the extent of the changes in these parameters in group A significantly exceeded the extent of the changes in group B [TDS -11.3 ± 4.3 in group A vs -4.0 ± 6.0 in group B (p < 0.01); H/M ratio 0.31 ± 0.16 vs 0.14 ± 0.16 (p < 0.01); WR -13.8 ± 7.8 % vs -6.1 ± 8.9 % (p < 0.01)]. The hs-TnT level decreased significantly from 0.052 ± 0.043 to 0.041 ± 0.033 ng/ml (p < 0.05) in group A, but showed no significant change in group B. Moreover, in both groups, no relationships between the extent of changes in MIBG parameters and hs-TnT level were observed. Adding intravenous nicorandil to standard therapy provides additional benefits for CSNA and myocyte dysfunction over conventional therapy alone in AHF patients. Furthermore, the mechanisms of improvement in CSNA and myocyte dysfunction after nicorandil treatment in AHF patients were distinct. (orig.)

    Objective: To understand current the state of standardized anticoagulant therapy in patient with atrial fibrillation and analyze the factors that affect standard anticoagulant therapy, and at the same time, to make progress by the foundation of corresponding countermeasures. Methods:Diagnosed nonvalvular atrial fibrillation patients were history inspected for a period of 12 months (January-December 2010) in Nanjing Drum Tower Hospital Cardiovascular Department, CHADS2 scheme method was used to stratify atrial fibrillation patient and assess their risk of bleeding, the standardized anticoagulant therapy conditions were evaluated according to ACC/AHA/ESC (American College of Cardiology/American Heart Association/ European Society of Cardiology) atrial fibrillation treatment guidelines. Results: A total of 200 patients were enrolled, 39 (19.5%) patient were on warfarin anticoagulant therapy, among which 18 (46%)had international normalized ratio (INR) in therapeutic range (2.0~3.0). According to the CHADS2 scheme,143 patients were divided into the high risk group, in which only 31 were on warfarin anticoagulant treatment. Conclusion: The percentage of standard anticoagulant treatment in patients with atrial fibrillation is very low (40%), still more, the percentage of high risk patients using warfarin standard anticoagulant treatment was even low 22%. Further investigation and understanding of the causes of this phenomenon will help intervene effectively and improve the standard of anticoagulant therapy in patient with atrial fibrillation.%目的:了解心房颤动患者规范化抗凝治疗现状,分析影响规范化抗凝治疗的因素,同时为进一步提出相应的对策打下基础.方法:查阅2010年1~12月份南京鼓楼医院心内科明确诊断患有非瓣膜性心房颤动的患者病历,采用CHADS风险评分法对这些患者进行出血风险评估,根据ACC/AHA/ESC心房颤动治疗指南评价其规范化抗凝

    In Australia, manufacture of blood, tissues and biologicals must comply with the federal laws and meet the requirements of the Therapeutic Goods Administration (TGA) Manufacturing Principles as outlined in the current Code of Good Manufacturing Practice (cGMP). The Therapeutic Goods Order (TGO) No. 88 was announced concurrently with the new cGMP, as a new standard for therapeutic goods. This order constitutes a minimum standard for human blood, tissues and cellular therapeutic goods aimed at minimising the risk of infectious disease transmission. The order sets out specific requirements relating to donor selection, donor testing and minimisation of infectious disease transmission from collection and manufacture of these products. The Therapeutic Goods Manufacturing Principles Determination No. 1 of 2013 references the human blood and blood components, human tissues and human cellular therapy products 2013 (2013 cGMP). The name change for the 2013 cGMP has allowed a broadening of the scope of products to include human cellular therapy products. It is difficult to directly compare versions of the code as deletion of some clauses has not changed the requirements to be met, as they are found elsewhere amongst the various guidelines provided. Many sections that were specific for blood and blood components are now less prescriptive and apply to a wider range of cellular therapies, but the general overall intent remains the same. Use of 'should' throughout the document instead of 'must' allows flexibility for alternative processes, but these systems will still require justification by relevant logical argument and validation data to be acceptable to TGA. The cGMP has seemingly evolved so that specific issues identified at audit over the last decade have now been formalised in the new version. There is a notable risk management approach applied to most areas that refer to process justification and decision making. These requirements commenced on 31 May 2013 and a 12 month

    through passive transport within the tumor. Recent advances have enhanced the diffusion of pharmaceuticals through active transport by using pharmaceuticals designed to target the genome of tumors. In the present study, five patients with non-small cell lung cancer epidermal growth factor receptor (EGFR negative stage IIIa–IV International Union Against Cancer 7 (UICC-7, and with Eastern Cooperative Oncology Group (ECOG 2 scores were administered platinum-based doublet chemotherapy using combined intratumoral-regional and intravenous route of administration. Cisplatin analogues were injected at 0.5%–1% concentration within the tumor lesion and proven malignant lymph nodes according to pretreatment histological/cytological results and the concentration of systemic infusion was decreased to 70% of a standard protocol. This combined intravenous plus intratumoral-regional chemotherapy is used as a first line therapy on this short series of patients. To the best of our knowledge this is the first report of direct treatment of involved lymph nodes with cisplatin by endobronchial ultrasound drug delivery with a needle without any adverse effects. The initial overall survival and local response are suggestive of a better efficacy compared to established doublet cisplatin–based systemic chemotherapy in (higher standard concentrations alone according to the UICC 7 database expected survival. An extensive search of the literature was performed to gather information of previously published literature of intratumoral chemo-drug administration and formulation for this treatment modality. Our study shows a favorable local response, more than a 50% reduction, for a massive tumor mass after administration of five sessions of intratumoral chemotherapy plus two cycles of low-dose intravenous chemotherapy according to our protocol. These encouraging results (even in very sick ECOG 2 patients with central obstructive non-small cell lung cancer having a worse prognosis and quality of

    After more than two decades the treatment effect of cement augmentation of osteoporotic vertebral compression fractures (VCF) has now been questioned by two blinded randomised placebo-controlled trials. Thus many practitioners are uncertain on the recommendation for cement augmentation techniques in elderly patients with osteoporotic VCF. This systematic review analyses randomised controlled trials on vertebroplasty and kyphoplasty to provide an overview on the current evidence. From an electronic database research 8 studies could be identified meeting our inclusion criteria of osteoporotic VCF in elderly (age>60 years), treatment with vertebroplasty or kyphoplasty, controlled with placebo or standard medical therapy, quality of life, function, or pain as primary parameter, and randomisation. Only two studies were properly blinded using a sham-operation as control. The other studies were using a non-surgical treatment control group. Further possible bias may be caused by manufacturer involvement in financing of three published RCT. There is level Ib evidence that vertebroplasty is no better than placebo, which is conflicting with the available level IIb evidence that there is a positive short-term effect of cement augmentation compared to standard medical therapy with regard to QoL, function and pain. Kyphoplasty is not superior to vertebroplasty with regard to pain, but with regard to VCF reduction (evidence level IIb). Kyphoplasty is probably not cost-effective (evidence level IIb), and vertebroplasty has not more than short-term cost-effectiveness (evidence level IV). Vertebroplasty and kyphoplasty cannot be recommended as standard treatment for osteoporotic VCF. Ongoing sham-controlled trials may provide further evidence in this regard.

    The present study represents one of the first comparisons of the long-term effectiveness of traditional cognitive behavior therapy (i.e., Beckian cognitive therapy; CT) and acceptance and commitment therapy (ACT). One hundred thirty-two anxious or depressed outpatients were randomly assigned to receive either CT or ACT, and were assessed at posttreatment (n=90) and at 1.5-year (n=91) follow-up. As previously reported, the two treatments were equivalently effective at posttreatment according to measures of depression, anxiety, overall (social/occupational/symptom-related) functioning, and quality of life. However, current results suggest that treatment gains were better maintained at follow-up in the CT condition. Clinical significance analyses revealed that, at follow-up, one-third more CT patients were in the clinically normative range in terms of depressive symptoms and more than twice as many CT patients were in the normative range in terms of functioning levels. The possible long-term advantage of CT relative to ACT in this population is discussed. Copyright © 2012. Published by Elsevier Ltd.

    With the recent emergence of immunotherapies and novel targeted treatments for advanced and metastatic melanoma such as selective B-Raf inhibitors and checkpoint inhibitors, the treatment landscape in Europe has changed considerably. The aim of this review was to provide an overview of current treatment pathways in Europe for the treatment of advanced melanoma, unresectable stage III-IV. A literature search of four databases was conducted to identify publications reporting on the treatment patterns of advanced and metastatic melanoma (stage III-IV) in European populations. Seven full-text publications and two conference abstracts reported on observational studies of melanoma treatment practices in France, Italy and the United Kingdom. Treatment patterns were identified for two time periods: 2005-2009 and 2011-2012. Common treatments reported for both periods included chemotherapy with dacarbazine, fotemustine or temozolomide. The main differences between the two periods were the introduction and prescription of immunotherapy ipilimumab and targeted therapy vemurafenib between 2011 and 2012. Across the three countries studied, the types of treatments prescribed between 2005 and 2009 were relatively similar, however, with noticeable differences in the frequency and priority of administration. Treatment practices for advanced melanoma vary markedly across different European countries and continue to evolve with the introduction of new therapies. The results of this review highlight a considerable evidence gap with regards to recent treatment patterns for advanced melanoma in Europe, especially post-2011 after the introduction of novel therapeutic agents, and more recently with the introduction of programmed cell death 1 inhibitors.
