This paper presents the results of the Probabilistic Safety Assessment (PSA) to the Cobalt Therapy Treatment Process in the Oncological Unit of Pinar del Rio city to evaluate occupational, public and medical exposures during cobalt therapy treatment. Equipment's Failures Modes and Human Error were evaluated for each system and treatment stage aimed at obtaining an exhaustive list of the deviations with a reasonable probability to occur and may produce significant adverse outcomes. The lowest exposures probabilities correspond to the public exposures during the treatment process; around 10-10 per year, being the workers exposures around 10-4 per year. Regarding the patient, exposures frequencies vary in dependence of the extent to which the error affect individual treatment, individual patients, or all the patients treated on a specific unit

[Dependent patient and interpersonal dependency: psychotherapeutic strategies].

2012-04-01

This article is a review of psychotherapies for patients suffering from dependent personality and interpersonal dependency. We synthesized articles making reference to this question, notably those written by Bornstein, author who refers to the dependent personality. We highlighted the psychotherapies that have been the object of an evaluation. The research on the subject is sparse: only eight studies permitting assessment of psychotherapies in this indication in 2005. Besides these psychotherapies, we detailed other approaches which are used by practitioners in these indications. The therapy does not aim at autonomy "at all costs", but that the patient finds a dependence "adapted" to his/her environment. Before starting a therapy, an evaluation is useful to specify the type of dependence. First of all, is there a "pathological" dependence? Is the suffering of the patient secondary to his personality or not supportive enough? Does insight exist? What is the reaction of the patient if we suggest the hypothesis of a dependence on his/her part? Does he/she consider this idea or reject it? Finally, is the dependence primary or secondary? For that purpose, it is necessary to study the biography of the patient and the appearance of the comorbidity over time. The primary dependence is seen in childhood and precedes the other psychological disorders. The secondary dependence follows after the comorbidity and events of life that alter self-esteem (depression, for example). Various therapeutic strategies arise from various currents. The therapies of analytical inspiration recommend replaying the relationship of object and explicitly evoking the transfer. The behavioural and cognitive psychotherapies aim at making the patient identify the cognitions which underlie the dependence, then leading the patient to modify his/her cognition and to behave in a more autonomous way, using the theory of learning. The humanist therapies aim at a therapeutic relationship of acceptance and

The application of superparamagnetic nanoparticles as heating agents in hyperthermia therapy has made a therapeutic breakthrough in cancer treatment. The high efficiency of this magnetic hyperthermia therapy has derived from a great capability of superparamagnetic nanoparticles to generate focused heat in inaccessible tumors being effectively inactivated. The main challenges of this therapy are the improvement of the induction heating power of superparamagnetic nanoparticles and the control of the hyperthermia temperature in a secure range of 42 °C to 47 °C, at targeted area. The variation of these hyperthermia properties is principally dependent on the magnetic nanoparticles as well as the magnetic field leading to enhance the efficiency of magnetic hyperthermia therapy at targeted area and also avoid undue heating to healthy cells. The present study evaluates the magnetic hyperthermia therapy through the determination of superparamagnetic nanoparticles properties and magnetic field’ parameters.

There is inconsistent evidence that alcohol-specific coping is a mechanism of change in cognitive-behavioral therapy (CBT) for alcohol use disorder (AUD). Our primary aim was to test whether baseline dependence severity moderates the mediational effect of CBT on drinking outcomes via coping. Secondary data analysis of Project MATCH , a multi-site alcohol treatment trial in which participants, recruited in out-patient and aftercare arms, were randomized to three treatments: CBT, motivational enhancement therapy (MET) and Twelve-Step facilitation (TSF). Nine research sites in the United States. A total of 1063 adults with AUD. The primary outcomes were percentage days abstinent and percentage heavy drinking days at the 1-year follow-up. Coping was assessed with the Processes of Change Questionnaire . Dependence severity was measured with the Alcohol Dependence Scale . Among the full available sample (across treatment arms), there were no significant moderated mediation effects. Double moderated mediation analyses indicated that several moderated mediation effects were moderated by treatment arm (all P cognitive-behavioral therapy for alcohol use disorder was conditional on dependence severity. End-of-treatment coping mediated the positive treatment effects of cognitive-behavioral therapy on 1-year drinking outcomes among out-patient clients when dependence severity was high, but not when dependence severity was low or moderate. © 2017 Society for the Study of Addiction.

The personality trait of dependence is common in health-seeking behaviour. We therefore examined its impact in a large randomized controlled trial of psychological treatment for health anxiety. To test whether dependent personality traits were positive or negative in determining the outcome of an adapted form of cognitive behaviour therapy for health anxiety (CBT-HA) over the course of 5 years and whether dependent personality dysfunction could be viewed dimensionally in a similar way to the new ICD-11 diagnostic system for general personality disorder. Dependent personality dysfunction was assessed using a self-rated questionnaire, the Dependent Personality Questionnaire, at baseline in a randomized controlled trial of 444 patients from medical clinics with pathological health anxiety treated with a modified form of CBT-HA or standard treatment in the medical clinics, with assessment on five occasions over 5 years. Dependent personality dysfunction was assessed using four severity groups. Patients with mild and moderate dependent personality disorder treated with CBT-HA showed the greatest reduction in health anxiety compared with standard care, and those with no dependent dysfunction showed the least benefit. Patients with higher dependent traits received significantly more treatment sessions (8.6) than those with low trait levels (5.4) (p dependent personality. The reasons for this may be related to better adherence to psychological treatment and greater negative effects of frequent reassurance and excessive consultation in those treated in standard care.

Guidance on Dependence Assessment in SPAR-H

Energy Technology Data Exchange (ETDEWEB)

April M. Whaley

2012-06-01

As part of the effort to develop the SPAR-H user guidance, particular attention was paid to the assessment of dependence in order to address user questions about proper application of dependence. This paper presents a discussion of dependence from a psychological perspective and provides guidance on applying this information during the qualitative analysis of dependence to ensure more realistic and appropriate dependence assessments with the SPAR-H method. While this guidance was developed with SPAR-H in mind, it may be informative to other human reliability analysis methods that also use a THERP-based dependence approach, particularly if applied at the human failure event level.

Anderson, Deborah K; Irwin, Kent E

2013-01-01

With the physical therapy (PT) professions' advancement to the clinical doctorate degree and the promotion of autonomous practice, exemplary professional conduct is an expectation of the PT profession. PT education programs are being challenged to develop methods to teach and assess professional behavior. Forty-three PT students (11 male and 32 female, ages 20-28 years) completed the APTA Professionalism in Physical Therapy: Core Values Self-Assessment (PPTCVSA) after their first 3 week clinical experience and again after their final clinical experience. A mixed design ANOVA compared participants' total scores and individual Core Value scores on the Professionalism in Physical Therapy: Core Values Self-Assessment (PPTCVSA) after 3 and 33 weeks of clinical education. The effects of gender, age, and undergraduate area of study on growth in professionalism scores were also investigated. Total PPTCVSA scores and individual Core Value scores on professionalism (accountability, altruism, compassion/caring, excellence, integrity, professional duty, and social responsibility) were higher after 33 weeks compared to scores after 3 weeks of clinical education. Female student's total professionalism scores were higher than male student's scores on both the first and second self-assessments. In addition, female students scored themselves higher than their male peers on accountability, excellence, integrity, and professional duty. Improved scores on the PPTCVSA indicate that physical therapy education is playing an important role in the development of professional behavior, knowledge, and application in practice.

This study examined the association among healthy and maladaptive aspects of interpersonal dependency and the management of pain in physical therapy outpatients. Ninety-eight patients were administered the Relationship Profile Test, West Haven-Yale Multidimensional Pain Inventory, and Pain Catastrophizing Scale. Results indicated that Destructive Overdependence was positively associated with an increased number of office visits, pain interference in one's daily life, pain severity, affective distress, and receiving positive partner responses. Dysfunctional Detachment was associated with affective distress, pain interference in one's daily life, and rumination about pain. Healthy Dependency was only associated with receiving distracting responses from others. Believing that a spouse/partner is supportive and caring about one's pain partially mediated the relationship between overdependency and pain interfering in one's life. These results support the clinical utility of assessing interpersonal dependency for its relationship to managing one's pain and health care utilization.

Radioiodine therapy induces dose-dependent in-vivo oxidation injury

Until now, radiation hazards as a consequence of radioiodine therapy are not examined in detail. Oxidation of lipoproteins may favour vasculopathy. We studied the influence of a single radioiodine therapy with 5 (n=8; 46-71a), 10 (n=6; 54-75a), 20 (n=11; 45-73a), 80 (n=6; 37-75a) or 200 (n=6; 43-67a) mCi on in-vivo oxidation injury in blood (plasma [P], serum [Se]), urine (U) and saliva (Sa) in patients suffering from hyperthyroidism opr thyroid cancer, respectively. The isoprostane 8-epi-prostaglandin (PG) F 2α as a marker of in-vivo oxidation injury (Sa, Se, P, U), oxidation of lipoproteins (LDL, HDL), thromboxane B2 (Sa, Se, P, U), PGE 2 , PGF 2α and circulating endothelial cells (CEC) were examined before therapy, daily for 7 days and weekly thereafter for 6 weeks. Blood was also analyzed for thiobarbituric acid reactive substances (TBARS), relative electrophoretic mobility (REM), baseline dienes (BD), endogenous peroxides (POX) and formation of conjugated dienes in copper-mediated oxidation (CD) expressed in lag-time and rate of propagation. There is a dose-dependent increase in 8-epi-PGF 2α being most pronounced in saliva (p 2 and HDL 3 subfractions 24 h after application, but 48 h and 72 h after application there was a significant increase in TBARS, REM, BD, POX and rate of propagation and a decrease in lag-time in HDL-subfractions independently from applied dose. Also HDL 2 showed more TBARS, REM, BD, POX and shorter lag-time than HDL 3 48 h after application, but this effect was reversed 72 h after application. HDL is the lipoprotein most prone to oxidation by radioiodine treatment. Apparently, when LDL becomes oxidized, it shifts metabolically its oxidation products to HDL. These findings show a significant temporary and dose-dependent endothelial desquamation, oxidation of lipoproteins and long-lasting in-vivo oxidation injury (saliva > urine > blood) as side effect of radioiodine therapy, altogether being potentially proatherogenic

2000-01-01

The present investigation was undertaken in response to music therapists working in school settings for information relating to the availability of music therapy assessments and the feasibility of standardizing an assessment instrument for music therapists to use in school settings. Five research questions were identified, and the music therapy literature was surveyed to compile responses to those questions. Three different online data bases (ERIC, PsycINFO, and Article 1st) were used, covering articles published between 1980 and 1997. Individual hand searches were done of the Arts in Psychotherapy, Journal of Music Therapy, Journal of Research in Music Education, Journal of the International Association of Music for the Handicapped, Music Therapy and Music Therapy Perspectives. The questions and responses were as follows: 1. Which music-based assessment tools are being used with children with disabilities? Little commonality in assessment tools being used by music therapists and researchers was discovered. Of the total 41 studies, 20 (49%) reported using a "named" or "titled" assessment tool, and in the remaining 51% of studies, the authors reported using an untitled, and usually experimenter-designed, original assessment tool. 2. Have certain assessments been used in more than one study? Very limited replication of existing assessments was found. Of the 16 "named" assessments, only 3 were found to be used in more than one research study. 3. Are the actual assessments published along with the articles describing their use? Only 3 of the 20 studies using named assessments were published along with the journal article. Of the remaining 21 studies using original, experimenter-designed assessment tools, only 6 (28%) had the assessment instrument published with the article. 4. What is the primary purpose for using the assessment? Six primary purposes emerged from the review of the literature: to compare with data obtained from other assessment measures or from other

Implant therapy in the esthetic zone: smile line assessment.

2011-04-01

Assessment of the smile or lip line is imperative when implant therapy is carried out in the esthetic zone. The smile is generally defined as high, average, or low. Females are reported to have higher lip lines than males, which means that they are at greater risk when placing and restoring implants in the esthetic zone. Maximum upper lip elevation, usually observed during a strained posed smile, should be assessed. This paper discusses some clinical observations and concepts in relation to smile line assessment for implant therapy in the esthetic zone. (Int J Periodontics Restorative Dent 2011;31:195-201.).

Drospirenone (DRSP) is a progestin with anti-aldosterone properties and it reduces blood pressure in hypertensive women. However, the effects of DRSP on endothelium-dependent coronary vasodilation have not been evaluated. This study investigated the effects of combined therapy with estrogen (E2) and DRSP on endothelium-dependent vasodilation of the coronary bed of ovariectomized (OVX) spontaneously hypertensive rats. Female spontaneously hypertensive rats (n=87) at 12 weeks of age were randomly divided into sham operated (Sham), OVX, OVX treated with E2 (E2), and OVX treated with E2 and DRSP (E2+DRSP) groups. Hemodynamic parameters were directly evaluated by catheter insertion into the femoral artery. Endothelium-dependent vasodilation in response to bradykinin in the coronary arterial bed was assessed using isolated hearts according to a modified Langendorff method. Coronary protein expression of endothelial nitric oxide synthase and estrogen receptor alpha (ER-α) was assessed by Western blotting. Histological slices of coronary arteries were stained with hematoxylin and eosin, and morphometric parameters were analyzed. Oxidative stress was assessed in situ by dihydroethidium fluorescence. Ovariectomy increased systolic blood pressure, which was only prevented by E2+DRSP treatment. Estrogen deficiency caused endothelial dysfunction, which was prevented by both treatments. However, the vasodilator response in the E2+DRSP group was significantly higher at the three highest concentrations compared with the OVX group. Reduced ER-α expression in OVX rats was restored by both treatments. Morphometric parameters and oxidative stress were augmented by OVX and reduced by E2 and E2+DRSP treatments. Hormonal therapy with E2 and DRSP may be an important therapeutic option in the prevention of coronary heart disease in hypertensive post-menopausal women

Plasticity of the cell state has been proposed to drive resistance to multiple classes of cancer therapies, thereby limiting their effectiveness. A high-mesenchymal cell state observed in human tumours and cancer cell lines has been associated with resistance to multiple treatment modalities across diverse cancer lineages, but the mechanistic underpinning for this state has remained incompletely understood. Here we molecularly characterize this therapy-resistant high-mesenchymal cell state in human cancer cell lines and organoids and show that it depends on a druggable lipid-peroxidase pathway that protects against ferroptosis, a non-apoptotic form of cell death induced by the build-up of toxic lipid peroxides. We show that this cell state is characterized by activity of enzymes that promote the synthesis of polyunsaturated lipids. These lipids are the substrates for lipid peroxidation by lipoxygenase enzymes. This lipid metabolism creates a dependency on pathways converging on the phospholipid glutathione peroxidase (GPX4), a selenocysteine-containing enzyme that dissipates lipid peroxides and thereby prevents the iron-mediated reactions of peroxides that induce ferroptotic cell death. Dependency on GPX4 was found to exist across diverse therapy-resistant states characterized by high expression of ZEB1, including epithelial-mesenchymal transition in epithelial-derived carcinomas, TGFβ-mediated therapy-resistance in melanoma, treatment-induced neuroendocrine transdifferentiation in prostate cancer, and sarcomas, which are fixed in a mesenchymal state owing to their cells of origin. We identify vulnerability to ferroptic cell death induced by inhibition of a lipid peroxidase pathway as a feature of therapy-resistant cancer cells across diverse mesenchymal cell-state contexts.

Porphyrin-based Nanostructure-Dependent Photodynamic and Photothermal Therapies

Science.gov (United States)

Jin, Cheng S.

This thesis presents the investigation of nanostructure-dependent phototherapy. We reviewed the liposomal structures for delivery of photosensitizers, and introduced a novel class of phototransducing liposomes called "porphysomes". Porphysomes are self-assembled from high packing density of pyropheophorbide alpha-conjugated phospholipids, resulting in extreme self-quenching of porphyrin fluorescence and comparable optical absorption to gold nanoparticles for high photothermal efficiency. We demonstrated this self-assembly of porphyrin-lipid conjugates converts a singlet oxygen generating mechanism (photodynamic therapy PDT activity) of porphyrin to photothermal mechanism (photothermal therapy PTT activity). The efficacy of porphysome-enhanced PTT was then evaluated on two pre-clinical animal models. We validated porphysome-enabled focal PTT to treat orthotopic prostate cancer using MRI-guided focal laser placement to closely mimic the current clinic procedure. Furthermore, porphysome-enabled fluorescence-guided transbronchial PTT of lung cancer was demonstrated in rabbit orthotopic lung cancer models, which led to the development of an ultra-minimally invasive therapy for early-stage peripheral lung cancer. On the other hand, the nanostructure-mediated conversion of PDT to PTT can be switched back by nanoparticle dissociation. By incorporating folate-conjugated phospholipids into the formulation, porphysomes were internalized into cells rapidly via folate receptor-mediated endocytosis and resulted in efficient disruption of nanostructures, which turned back on the photodynamic activity of densely packed porphyrins, making a closed loop of conversion between PDT and PTT. The multimodal imaging and therapeutic features of porphysome make it ideal for future personalized cancer treatments.

Urine protein electrophoresis study in dogs with pituitary dependent hyperadrenocorticism during therapy with trilostane

Douglas S. Caragelasco

Full Text Available ABSTRACT: Hyperadrenocorticism is one of the most common endocrine disorders in dogs. Regarding to the kidneys, chronic hypercortisolemia can cause damage to the glomerulus, and evolve into chronic kidney disease. This study evaluated nine normotensive dogs with pituitary dependent hyperadrenocorticism, before and after therapy with trilostane, during the follow-up period of six months, in order to investigate the development of pathological proteinuria by quantitative (urinary protein-to-creatinine ratio and qualitative (urinary protein electrophoresis methods, and also to monitor its intensity over the course of the disease and therapy. The main renal lesion detected in dogs with hyperadrenocorticism was in the tubular segment, evidenced by the prevalence of urinary protein bands of lower molecular weight, indicating the lack absorption of these proteins in the proximal segment of the nephron. Low molecular weight proteins persisted throughout the follow-up. Regarding the future of routine veterinary medical clinic in the care of patients with hyperadrenocorticism, the assessments of proteinuria determinations by the urinary protein-to-creatinin ratio and urinary protein electrophoresis, according to the results obtained in this study, can add more information about the renal damage in these animals, and contribute to the prognosis.

Full Text Available Acute weaning from chronic opioid abuse during general anesthesia is usually followed by adrenergic outflow effects. This article is to report our experience with accelerated neuroregulation that reverses the physical and psychological dependency. After a comprehensive psychological and medical examination, 361 heroin dependent patients were admitted to ICU to be hospitalized for a full 24 or 36 hours, including a 6 hour pre-procedure medication process (solbutamol, clonidine, diazepam, ranitidine, omeprazole, vitamin C, octreotide, and ondansetron. Anesthesia was induced with midazolam and propofol iv and maintained with propofol infusion. Naltrexon, clonidine, octreotide, and diazepam were then administered. Anesthesia was maintained for 3 ½ - 5 hours depending on severity of withdrawal symptoms precipitated by naltrexone. Analgetics and sedatives were given as needed afterwards. Upon discharge on the following day, patient was prescribed a regimen of oral naltrexone for 10-12 months. All 361 patients were successfully detoxified without any adverse anesthetic events. The side effects encountered were fatigue, insomnia, drowsy, shivering, abdominal pain, nausea, diarrhoea, myalgia, goose bumps and uncomfortable feeling. In most of the patients these symptoms disappeared without any treatment. Symptomatic treatments were needed in 32.7% of patients. In all 166 patients who completed their naltrexone maintenance treatment, craving disappeared in the 10th month. The main problem was the low patient compliance to oral naltrexone, so that only 45.9% of the patients completed their therapy. Conclusion: Accelerated neuroregulation which includes naltrexone maintenance treatment (10-12 months was highly effective to detoxify and to abolish craving in the heroin dependent patients.

Accurate assessment of range uncertainty is critical in proton therapy. However, there is a lack of data and consensus on how to evaluate the appropriate amount of uncertainty. The purpose of this study is to quantify the range uncertainty in various treatment conditions in proton therapy, using transmission measurements through various animal tissues. Animal tissues, including a pig head, beef steak, and lamb leg, were used in this study. For each tissue, an end-to-end test closely imitating patient treatments was performed. This included CT scan simulation, treatment planning, image-guided alignment, and beam delivery. Radio-chromic films were placed at various depths in the distal dose falloff region to measure depth dose. Comparisons between measured and calculated doses were used to evaluate range differences. The dose difference at the distal falloff between measurement and calculation depends on tissue type and treatment conditions. The estimated range difference was up to 5, 6 and 4 mm for the pig head, beef steak, and lamb leg irradiation, respectively. Our study shows that the TPS was able to calculate proton range within about 1.5% plus 1.5 mm. Accurate assessment of range uncertainty in treatment planning would allow better optimization of proton beam treatment, thus fully achieving proton beams’ superior dose advantage over conventional photon-based radiation therapy.

Dose Dependent Survival Response in Chronic Myeloid Leukemia under Continuous and Pulsed Targeted Therapy

Pizzolato, N.; Valenti, D.; Spagnolo, B.; Persano Adorno, D.

2010-01-01

A simulative study of cancer growth dynamics in patients affected by Chronic Myeloid Leukemia (CML), under the effect of a targeted dose dependent continuous or pulsed therapy, is presented. We have developed a model for the dynamics of CML in which the stochastic evolution of white blood cell populations are simulated by adopting a Monte Carlo approach. Several scenarios in the evolutionary dynamics of white blood cells, as a consequence of the efficacy of the different modelled therapies, pulsed or continuous, are described. The best results, in terms of a permanent disappearance of the leukemic phenotype, are achieved with a continuous therapy and higher dosage. However, our findings demonstrate that an intermittent therapy could represent a valid choice in patients with high risk of toxicity, when a long-term therapy is considered. A suitably tuned pulsed therapy can enhance the treatment efficacy and reduce the percentage of patients developing resistance. (authors)

The current study evaluates a therapy for substance-dependent perpetrators of partner violence. Sixty-three males arrested for partner violence within the past year were randomized to a cognitive behavioral substance abuse-domestic violence (SADV; n = 29) or a drug counseling (DC; n = 34) condition. Seventy percent of offenders completed eight core sessions with no differences between SADV and DC conditions in the amount of substance or aggression at pretreatment. SADV participants had fewer cocaine-positive toxicology screens and breathalyzer results during treatment, were less likely to engage in aggressive behavior proximal to a drinking episode, and reported fewer episodes of violence than DC participants at posttreatment follow-up. SADV shows promise in decreasing addiction and partner violence among substance-dependent male offenders. © 2017 American Association for Marriage and Family Therapy.

ANTIPLATELET THERAPY IN THE PREVENTION OF CEREBROVASCULAR ACCIDENTS

Directory of Open Access Journals (Sweden)

2017-01-01

Full Text Available Currently the problem of preventing cerebrovascular disorders, in which antiplatelet therapy takes one of the leading places, remains relevant. The efficiency of the therapy depends on a large number of modifiable and non-modifiable factors. There are many methods to assess the severity of the response to antiplatelet therapy, but there is no common approach to the assessment of the results and their prognostic significance. Further studies of this issue are essential with the aim of individualization of antiplatelet therapy thereby increasing its efficiency and safety.

Australian accreditation standards for occupational therapy courses require consumer participation in the design, delivery and evaluation of programs. This study investigated whether a mental health consumer - as one of two assessors for an oral assessment in a mental health unit - impacted engagement, anxiety states and academic performance of undergraduate occupational therapy students. Students (n = 131 eligible) self-selected into two groups but were blinded to the group differences (assessor panel composition) until shortly prior to the oral assessment. Control group assessors were two occupational therapy educators, while consumer group assessors included an occupational therapy educator and a mental health consumer. Pre- and post-assessment data were successfully matched for 79 students (overall response rate = 73.1%). No evidence was found of significant differences between the two groups for engagement, anxiety or academic performance (all P values >0.05). Including mental health consumers as assessors did not negatively impact student engagement and academic performance, nor increase student anxiety beyond that typically observed in oral assessment tasks. The findings provide support for expanding the role of mental health consumers in the education and assessment of occupational therapy students. Development of methods to determine the efficacy of consumer involvement remains an area for future research. © 2018 Occupational Therapy Australia.

2014-01-01

Purpose of review EDTA chelation therapy has been in off-label use for the treatment of atherosclerosis. We review the results of the first large-scale randomized trial of this treatment. Recent findings The trial to assess chelation therapy was a $30 million National Institutes of Health-funded study of the safety and efficacy of EDTA-based chelation infusions in 1708 post-myocardial infarction (MI) patients. The trial to assess chelation therapy demonstrated a significant (P = 0.035) 18% reduction in a combined primary endpoint of death, MI, stroke, coronary revascularization, or hospitalization for angina. In diabetic patients the benefit was more extreme, with a 41% relative reduction in risk (P = 0.0002) and a 43% reduction in total mortality (P = 0.011). Safety data were favorable. A reduction of oxidative stress by chelation of toxic metals has been proposed as a possible mechanism of action. Summary Recent research suggests that EDTA chelation may be a well-tolerated and effective treatment for post-MI patients. Future replication and mechanistic studies are important prior to implementation in all post-MI patients. PMID:25023079

A variety of methods have been developed to assess tumor response to therapy. Standardized qualitative criteria based on 18F-fluoro-deoxyglucose PET/computed tomography have been proposed to evaluate the treatment effectiveness in specific cancers and these allow more accurate therapy response assessment and survival prognostication. Multiple studies have addressed the utility of the volumetric PET biomarkers as prognostic indicators but there is no consensus about the preferred segmentation methodology for these metrics. Heterogeneous intratumoral uptake was proposed as a novel PET metric for therapy response assessment. PET imaging techniques will be used to study the biological behavior of cancers during therapy.

Highlights: • D numbers and AHP are combined to implement dependence assessment in HRA. • A new tool, called D numbers, is used to deal with the uncertainty in HRA. • The proposed method can well address the fuzziness and subjectivity in linguistic assessment. • The proposed method is well applicable in dependence assessment which inherently has a linguistic assessment process. - Abstract: Since human errors always cause heavy loss especially in nuclear engineering, human reliability analysis (HRA) has attracted more and more attention. Dependence assessment plays a vital role in HRA, measuring the dependence degree of human errors. Many researches have been done while still have improvement space. In this paper, a dependence assessment model based on D numbers and analytic hierarchy process (AHP) is proposed. Firstly, identify the factors used to measure the dependence level of two human operations. Besides, in terms of the suggested dependence level, determine and quantify the anchor points for each factor. Secondly, D numbers and AHP are adopted in model. Experts evaluate the dependence level of human operations for each factor. Then, the evaluation results are presented as D numbers and fused by D number’s combination rule that can obtain the dependence probability of human operations for each factor. The weights of factors can be determined by AHP. Thirdly, based on the dependence probability for each factor and its corresponding weight, the dependence probability of two human operations and its confidence can be obtained. The proposed method can well address the fuzziness and subjectivity in linguistic assessment. The proposed method is well applicable to assess the dependence degree of human errors in HRA which inherently has a linguistic assessment process.

2012-01-01

Full Text Available Treatment programs based on a neurophysiological model have shown a positive effect on anxiety and depression in tinnitus patients. The aim of this paper was to assess the long-term effect of tinnitus habituation therapy. Sixty-eight individuals were treated with a comprehensive therapy program. The degree of anxiety and depression was assessed before, after, and five years after intervention using the Hospital Anxiety and Depression Scale. The positive and significant changes achieved after habituation therapy (pre = 1.10, post = 0.92 for anxiety and pre = 0.77, post = 0.62 for depression were maintained five years after treatment ended (0.87 for anxiety and 0.52 for depression. A regression analysis revealed that individual evaluation of the treatment lectures, self-reported health condition, individual experiences of hyperacusis, and hearing loss could explain 44.3% of the variation in anxiety and 30.5% of the variation in depression posttreatment. Five years after, individual evaluation of the treatment lectures and self-reported health condition explained 22.2% of the variation in anxiety. These factors and individual experiences of hyperacusis could further explain 34.9% of the variation in depression. The effect of a neurophysiologic-based management treatment was maintained five years after treatment ended, indicating that the patients continued the improvement process without becoming dependent on professionals.

Fecal Microbiota Therapy for Clostridium difficile Infection: A Health Technology Assessment.

Science.gov (United States)

2016-01-01

Fecal microbiota therapy is increasingly being used to treat patients with Clostridium difficile infection. This health technology assessment primarily evaluated the effectiveness and cost-effectiveness of fecal microbiota therapy compared with the usual treatment (antibiotic therapy). We performed a literature search using Ovid MEDLINE, Embase, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, CRD Health Technology Assessment Database, Cochrane Central Register of Controlled Trials, and NHS Economic Evaluation Database. For the economic review, we applied economic filters to these search results. We also searched the websites of agencies for other health technology assessments. We conducted a meta-analysis to analyze effectiveness. The quality of the body of evidence for each outcome was examined according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. Using a step-wise, structural methodology, we determined the overall quality to be high, moderate, low, or very low. We used a survey to examine physicians' perception of patients' lived experience, and a modified grounded theory method to analyze information from the survey. For the review of clinical effectiveness, 16 of 1,173 citations met the inclusion criteria. A meta-analysis of two randomized controlled trials found that fecal microbiota therapy significantly improved diarrhea associated with recurrent C. difficile infection versus treatment with vancomycin (relative risk 3.24, 95% confidence interval [CI] 1.85-5.68) (GRADE: moderate). While fecal microbiota therapy is not associated with a significant decrease in mortality compared with antibiotic therapy (relative risk 0.69, 95% CI 0.14-3.39) (GRADE: low), it is associated with a significant increase in adverse events (e.g., short-term diarrhea, relative risk 30.76, 95% CI 4.46-212.44; abdominal cramping, relative risk 14.81, 95% CI 2.07-105.97) (GRADE: low).

Objective To determine whether measures of ovarian reserve differ between females exposed to cancer therapies in a dose-dependent manner as compared to healthy controls of similar age and late-reproductive age. Design Cross-sectional analysis of data from a prospective cohort study Setting University Medical Center Patients 71 cancer survivors age 15-39; 67 healthy, similarly aged unexposed subjects; 69 regularly menstruating women of late-reproductive age (40-52 years). Interventions: None Main Outcome measures Early follicular phase hormones (FSH, Estradiol, Inhibin B, AMH) and ovarian ultrasound measurements (ovarian volume and Antral Follicle Counts) were compared using multivariable linear regression. Results In adjusted models, FSH, AMH and AFC differed between exposed vs. unexposed (FSH 11.12mIU/ml vs. 7.25mIU/ml, p=0.001; AMH 0.81ng/ml vs. 2.85ng/ml, pscore was associated with increased levels of FSH (p= 0.016) and decreased levels of AMH (p=0.003). Exposure to pelvic radiation was associated with impairment in FSH, AMH, AFC and ovarian volume. AMH was similar in women previously exposed to high-dose cancer therapy and 40-42 year old controls. Conclusions Measures of ovarian reserve are impaired in a dose-dependent manner among cancer survivors compared to unexposed females of similar age. Reproductive hormone levels in menstruating survivors exposed to high-dose therapy are similar to late-reproductive women. The predictive value of measures for pregnancy and menopause must be studied. PMID:22137491

Implantable cardioverter defibrillators (ICDs) used to prevent sudden cardiac arrest in children not only provide appropriate therapy in 25% of patients but also result in a significant incidence of inappropriate shocks and other device complications. ICDs placed for secondary prevention have higher rates of appropriate therapy than those placed for primary prevention. Pediatric patients with primary prevention ICDs were studied to determine time-dependent incidence of appropriate use and adverse events. A total of 140 patients aged prevention were retrospectively identified. Demographics and times to first appropriate shock; adverse events (including inappropriate shock, lead failure, reintervention, and complication); generator replacement and follow-up were noted. During mean follow-up of 4 years, appropriate shock occurred in 19% patients and first adverse event (excluding death/transplant) occurred in 36%. Risk of death or transplant was ≈1% per year and was not related to receiving appropriate therapy. Conditional survival analysis showed rates of appropriate therapy and adverse events decrease soon after implantation, but adverse events are more frequent than appropriate therapy throughout follow-up. Primary prevention ICDs were associated with appropriate therapy in 19% and adverse event in 36% in this cohort. The incidence of both first appropriate therapy and device-related adverse events decreased during longer periods of follow-up after implantation. This suggests that indications for continued device therapy in pediatric primary prevention ICD patients might be reconsidered after a period of nonuse. © 2014 American Heart Association, Inc.

An increase in quantity of oral Candida albicans was documented in patients receiving head and neck radiation therapy during and after therapy, as assessed by an oral-rinse culturing technique. The amount of the increase was greater in denture wearers and directly related to increasing radiation dose and increasing volume of parotid gland included in the radiation portal. A significant number of patients who did not carry C. albicans prior to radiation therapy developed positive cultures by 1 month after radiation therapy. The percentage of patients receiving head and neck radiation therapy who carried C. albicans prior to radiation therapy did not differ significantly from matched dental patient controls

Emotion regulation and substance use frequency in women with substance dependence and borderline personality disorder receiving dialectical behavior therapy.

2011-01-01

Dialectical behavior therapy (DBT) identifies emotion dysregulation as central to the dangerous impulsivity of borderline personality disorder (BPD) including substance use disorders, and DBT targets improved emotion regulation as a primary mechanism of change. However, improved emotion regulation with DBT and associations between such improvement and behavioral outcomes such as substance use has not been previously reported. Thus, the goal of this study was to assess for improvement in emotion regulation and to examine the relationship between improvements in the emotion regulation and substance use problems following DBT treatment. Emotion regulation as assessed by the Difficulties in Emotion Regulation Scale, depressed mood as assessed by the Beck Depression Inventory, and their associations with substance use frequency were investigated in 27 women with substance dependence and BPD receiving 20 weeks of DBT in an academic community outpatient substance abuse treatment program. Results indicated improved emotion regulation, improved mood, and decreased substance use frequency. Further, emotion regulation improvement, but not improved mood, explained the variance of decreased substance use frequency. This is the first study to demonstrate improved emotion regulation in BPD patients treated with DBT and to show that improved emotion regulation can account for increased behavioral control in BPD patients. SIGNIFICANCE AND FUTURE RESEARCH: Emotion regulation assessment is recommended for future studies to further clarify the etiology and maintenance of disorders associated with emotional dysregulation such as BPD and substance dependence and to further explore emotion regulation as a potential mechanism of change for clinical interventions.

Development of a music therapy assessment tool for patients in low awareness states.

Science.gov (United States)

Magee, Wendy L

2007-01-01

People in low awareness states following profound brain injury typically demonstrate subtle changes in functional behaviors which challenge the sensitivity of measurement tools. Failure to identify and measure changes in functioning can lead to misdiagnosis and withdrawal of treatment with this population. Thus, the development of tools which are sensitive to responsiveness is of central concern. As the auditory modality has been found to be particularly sensitive in identifying responses indicating awareness, a convincing case can be made for music therapy as a treatment medium. However, little has been recommended about protocols for intervention or tools for measuring patient responses within the music therapy setting. This paper presents the rationale for an assessment tool specifically designed to measure responses in the music therapy setting with patients who are diagnosed as minimally conscious or in a vegetative state. Developed over fourteen years as part of interdisciplinary assessment and treatment, the music therapy assessment tool for low awareness states (MATLAS) contains fourteen items which rate behavioral responses across a number of domains. The tool can provide important information for interdisciplinary assessment and treatment particularly in the auditory and communication domains. Recommendations are made for testing its reliability and validity through research.

To investigate variables before sorafenib therapy on the clinical outcomes in hepatocellular carcinoma (HCC) patients receiving sorafenib and to further assess and compare the predictive performance of continuous parameters using time-dependent receiver operating characteristics (ROC) analysis. A total of 225 HCC patients were analyzed. We retrospectively examined factors related to overall survival (OS) and progression free survival (PFS) using univariate and multivariate analyses. Subsequently, we performed time-dependent ROC analysis of continuous parameters which were significant in the multivariate analysis in terms of OS and PFS. Total sum of area under the ROC in all time points (defined as TAAT score) in each case was calculated. Our cohort included 175 male and 50 female patients (median age, 72 years) and included 158 Child-Pugh A and 67 Child-Pugh B patients. The median OS time was 0.68 years, while the median PFS time was 0.24 years. On multivariate analysis, gender, body mass index (BMI), Child-Pugh classification, extrahepatic metastases, tumor burden, aspartate aminotransferase (AST) and alpha-fetoprotein (AFP) were identified as significant predictors of OS and ECOG-performance status, Child-Pugh classification and extrahepatic metastases were identified as significant predictors of PFS. Among three continuous variables (i.e., BMI, AST and AFP), AFP had the highest TAAT score for the entire cohort. In subgroup analyses, AFP had the highest TAAT score except for Child-Pugh B and female among three continuous variables. In continuous variables, AFP could have higher predictive accuracy for survival in HCC patients undergoing sorafenib therapy.

Full Text Available A range of methods in clinical research aim to assess treatment-induced progress in aphasia therapy. Here, we used a crossover randomized controlled design to compare the suitability of utterance-centered and dialogue-sensitive outcome measures in speech-language testing. Fourteen individuals with post-stroke chronic non-fluent aphasia each received two types of intensive training in counterbalanced order: conventional confrontation naming, and communicative-pragmatic speech-language therapy (Intensive Language-Action Therapy, an expanded version of Constraint-Induced Aphasia Therapy. Motivated by linguistic-pragmatic theory and neuroscience data, our dependent variables included a newly created diagnostic instrument, the Action Communication Test (ACT. This diagnostic instrument requires patients to produce target words in two conditions: (i utterance-centered object naming, and (ii communicative-pragmatic social interaction based on verbal requests. In addition, we administered a standardized aphasia test battery, the Aachen Aphasia Test (AAT. Composite scores on the ACT and the AAT revealed similar patterns of changes in language performance over time, irrespective of the treatment applied. Changes in language performance were relatively consistent with the AAT results also when considering both ACT subscales separately from each other. However, only the ACT subscale evaluating verbal requests proved to be successful in distinguishing between different types of training in our patient sample. Critically, testing duration was substantially shorter for the entire ACT (10–20 min than for the AAT (60–90 min. Taken together, the current findings suggest that communicative-pragmatic methods in speech-language testing provide a sensitive and time-effective measure to determine the outcome of aphasia therapy.

To verify the efficacy of group voice therapy in the stage of readiness and identify which items of the URICA-Voice range are more sensitive to post-therapy change in patients with behavioral dysphonia. An intervention study was conducted on 49 patients with behavioral dysphonia. An eclectic approach to group therapy was implemented over eight sessions, the first and last sessions consisting of assessments. The URICA-Voice range was used to evaluate the stage of readiness at pre- and post-therapy assessments. A descriptive and inferential statistical analysis was implemented for the results. Most participants were female, did not make professional use of voice, and had membranous vocal fold lesions. Most of them were in the Contemplation stage at in both moments, pre- and post-therapy. There was no significant change in the comparison of pre- and post-therapy scores. The majority of patients showed a reduction in the stage of readiness and some advanced to a higher stage. In the comparison of URICA-V range items, seven questions had equal or inferior responses in the post-therapy assessment. There was no statistical difference when comparing the pre- and post-therapy total average score of the URICA-Voice range. There were significant changes in the stage of readiness of patients in pre- and post-group speech therapy assessments.

Dahourou, D L; Leroy, V

2017-12-01

More than 3 million children aged less than 15years are infected with HIV worldwide, mainly in Sub-Saharan Africa. The survival of HIV-infected children depends on their access to antiretroviral therapy whose success mainly depends on a good life-long compliance with antiretroviral therapy. Given its complexity and specificity, assessment and monitoring of pediatric compliance with antiretroviral therapy is a major challenge. There is no consensus on a gold standard for monitoring compliance with antiretroviral therapy. Compliance is also influenced by many factors related to the child, the caregiver, the healthcare staff, the healthcare system, and antiretroviral drugs. This review aimed to assess scientific knowledge on pediatric compliance with antiretroviral therapy in Sub-Saharan Africa, and to identify areas for future interventions to improve compliance. Good compliance is essential to achieve the "90% coverage of children on antiretroviral therapy" gold standard of the World Health Organization, and to eliminate HIV infection by 2030.

Coronary artery bypass vein grafts are a mainstay of therapy for human atherosclerosis. Unfortunately, the long-term patency of vein grafts is limited by accelerated atherosclerosis. Gene therapy, directed at the vein graft wall, is a promising approach for preventing vein graft atherosclerosis. Because helper-dependent adenovirus (HDAd) efficiently transduces grafted veins and confers long-term transgene expression, HDAd is an excellent candidate for delivery of vein graft-targeted gene therapy. We developed a model of vein graft atherosclerosis in fat-fed rabbits and demonstrated long-term (≥20 weeks) persistence of HDAd genomes after graft transduction. This model enables quantitation of vein graft hemodynamics, wall structure, lipid accumulation, cellularity, vector persistence, and inflammatory markers on a single graft. Time-course experiments identified 12 weeks after transduction as an optimal time to measure efficacy of gene therapy on the critical variables of lipid and macrophage accumulation. We also used chow-fed rabbits to test whether HDAd infusion in vein grafts promotes intimal growth and inflammation. HDAd did not increase intimal growth, but had moderate-yet significant-pro-inflammatory effects. The vein graft atherosclerosis model will be useful for testing HDAd-mediated gene therapy; however, pro-inflammatory effects of HdAd remain a concern in developing HDAd as a therapy for vein graft disease.

Full Text Available Background and Aim: Statistics show that 30% to 40 % of  opium addicted fathers’ children are prone to substance abuse in the future. The present study aimed at assessing the effectiveness of cognitive therapy approach  to attitude changing of adolescents with substance dependent fathers. Materials and Methods:  In this controlled. field-trail randomized study. .data collection tool was “attitude to addiction questionnaire”. The study population was all male students in the first grade of high school in Maneh - Samalghan city. . Six sessions of group cognitive therapy based on the effectiveness of drug side-effects in drug-addicted fathers’ adolescent children’s attitude were held. The above-mentioned questionnaire was filled out before and after intervention. The obtained data  was fed into SPSS software (V: 16 using. Independent t-test .and paired t-test were used for analysis and P<0.05 was taken as the significant level. Results:  There were no significant differences between the two groups in pre-test regarding their attitude about drug abuse (P=.20%. Mean score variance from pre-test to post-test in the intervention group decreased, but in the control group, it showed a slight increase. This means that the intervention reduced the positive attitude towards drugs, but the changes were not statistically significant (p=0.57. Besides, among ten factors decisive in an individual’s attitude about addiction, only group cognitive therapy  was able  to decrease mean points of an individual’s attitude about drug abuse .. Significantly (P = 0.04. Conclusion: It was found that group cognitive therapy education about opium  addict complicationsdidn`t have a significant effect on the attitude of the students with addicted fathers. Thus, a change of adolescents’ attitude requires more research.

The Functional Assessment of Cancer Therapy (FACT)-Antiangiogenesis (AntiA) Subscale was developed and validated to enhance treatment decision-making and side effect management for patients receiving anti-angiogenesis therapies. Side effects related to anti-angiogenesis therapies were identified from the literature, clinician input, and patient input. Fifty-nine possible patient expressions of side effects were generated. Patient and clinician ratings of the importance of these expressions led us to develop a 24-item questionnaire with clinical and research potential. To assess the scale's reliability and validity, 167 patients completed the AntiA Subscale, the Functional Assessment of Cancer Therapy-general (FACT-G), the FACT-Kidney Symptom Index (FKSI), the FACIT-Fatigue Subscale, the Global Rating of Change Scale (GRC), and the PROMIS Global Health Scale. Patient responses to the AntiA were analyzed for internal consistency, test-retest reliability, convergent and discriminant validity, and responsiveness to change in clinical status. All tested scales were found to have good internal consistency reliability (Cronbach's alpha 0.70-0.92). Test-retest reliability was also good (0.72-0.88) for total and subscale scores and lower for individual items. The total score, subscale scores, and all single items (except nosebleeds) significantly differentiated between groups defined by level of side effect bother. Evaluation of responsiveness to change in this study was not conclusive, suggesting an area for further research. The AntiA is a reliable and valid measure of side effects from anti-angiogenesis therapy. © 2014 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

Treating Women Drug Abusers: Action Therapy and Trauma Assessment

Uhler, Ann S.; Parker, Olga V.

2002-01-01

The authors suggest that action therapy, a group of techniques including psychodrama, drama therapy, and role training, warrants research attention to determine whether it is well suited to the special characteristics and needs of women clients. In addition, the authors call on researchers to develop a new standardized tool for counselors to use during initial interviews to determine whether women presenting for drug abuse treatment also have significant issues related to trauma. The authors believe the use of unassisted clinical judgment for trauma assessment in first interviews may drive patients away by probing for painful information that clients are not yet ready to confront or divulge.

Continuing competence activities hold the promise of improving health-care service quality, especially given concerns about system inefficiencies and fragmentation. The aim of this scoping review was to describe the assessment and maintenance of occupational therapists' continuing competence and identify knowledge gaps for future research. A secondary aim was comparing scoping review findings with those from other health-care fields and considering possible impact of varying international regulations. A series of database searches retrieved peer-reviewed and grey literature on assessment and maintenance of occupational therapy continuing competence from 1995 to 2015. Themes were developed and findings shared with stakeholders, whose comments drove a second phase: searching for reviews related to continuing competence from allied health, medicine, and nursing, and reviewing websites and documents concerning regulatory requirements for occupational therapy continuing competence in seven English-speaking nations. Twenty-seven sources from the scoping review search met inclusion criteria. Stakeholder consultation validated the themes and preliminary knowledge gaps. Research into other health-care specialties corresponded to findings from the scoping review. The website/document review of occupational therapy regulatory requirements revealed wide variation on both the state/province and national levels. This scoping review highlights gaps in research on effective methods and assessment of occupational therapy continuing competence. Findings suggest a need for research on approaches to continuing competence that incorporate the translation of evidence to practice and address the influence of external factors. Regulatory agencies may address the quality of occupational therapy services by incorporating a variety of professional development options into requirements. © 2017 Occupational Therapy Australia.

Objective: To evaluate in a systematic review and meta-analysis model the effect of statin therapy on carotid plaque echogenicity assessed by ultrasound. Methods: We have systematically searched electronic databases (PubMed, MEDLINE, EMBASE and Cochrane Center Register) up to April, 2015, for studies evaluating the effect of statins on plaque echogenicity. Two researchers independently determined the eligibility of studies evaluating the effect of statin therapy on carotid plaque echogenicity that used ultrasound and grey scale median (GSM) or integrated back scatter (IBS). Results: Nine out of 580 identified studies including 566 patients’ carotid artery data were meta-analyzed for a mean follow up of 7.2 months. A consistent increase in the echogenicity of carotid artery plaques, after statin therapy, was reported. Pooled weighted mean difference % (WMD) on plaque echogenicity after statin therapy was 29% (95% CI 22%–36%), p < 0.001, I2 = 92.1%. In a meta-regression analysis using % mean changes of LDL, HDL and hsCRP as moderators, it was shown that the effects of statins on plaque echogenicity were related to changes in hsCRP, but not to LDL and HDL changes from the baseline. The effect of statins on the plaque was progressive; it showed significance after the first month of treatment, and the echogenicity continued to increase in the following six and 12 months. Conclusions: Statin therapy is associated with a favorable increase of carotid plaque echogenicity. This effect seems to be dependent on the period of treatment and hsCRP change from the baseline, independent of changes in LDL and HDL. PMID:25984600

To assess the efficacy of levamisole in frequently relapsing nephrotic syndrome and steroid-dependent nephrotic syndrome. Retrospective analysis of hospital case records. Pediatric nephrology department of a tertiary referral pediatric hospital. 62 children with frequently relapsing nephrotic syndrome and 35 children with steroid-dependent nephrotic syndrome. Case records of children who were diagnosed as steroid-dependant or frequently-relapsing nephrotic syndrome from June 2004 to June 2011, were reviewed. Levamisole was given daily (2 mg/kg/d) along with tapering doses of alternate day steroids after remission on daily steroids. Levamisole was effective in 77.3% children with a better (80.6%) efficacy in frequently relapsing nephrotic syndrome. A total of 34 children completed 1 year follow-up post levamisole therapy. The cumulative mean (SD) steroid dose 1-year before therapy was 4109(1154) mg/m2 and 1-year post therapy was 661 (11) mg/m2 (P<0.001). The relapses were also less during the period of post-levamisole therapy. Levamisole is an effective alternative therapy in frequently relapsing and steroid-dependent nephrotic syndrome.

The good tolerance of radionuclide therapy has frequently been proposed as a major advantage. This study explored the feasibility of using the EORTC QLQ-C30 questionnaire in palliative iodine-131 lipiodol therapy for hepatocellular carcinoma. Questionnaires were completed during interviews in which all symptoms, co-morbidity and medication were assessed at baseline within 1 week before 131 I-lipiodol therapy, and subsequently after 1 and 3 months, in 20 patients treated with locoregional, intra-arterial 131 I-lipiodol therapy with or without cisplatin. Principal observations were that (1) a number of important scales, i.e. overall quality of life, physical functioning and pain, worsened between 0 and 3 months after 131 I-lipiodol therapy, irrespective of tumour response, and (2) the occurrence of clinical side-effects was associated with a negative impact on quality of life and physical functioning 1 and 3 months after 131 I-lipiodol. The QLQ-C30 can be regarded as a feasible method for quality of life assessment in 131 I-lipiodol therapy for hepatocellular carcinoma and possibly in other radionuclide therapies. These observations should be related to the impact of other treatment modalities on quality of life. (orig.)

The interpersonal paradigm of personality assessment provides a rich nomological net for describing and assessing constructs of interpersonal functioning. The aim of this article is to demonstrate for clinicians how the use of a multisurface interpersonal assessment (MSIA) battery can augment psychotherapy (e.g., cognitive-behavioral therapy). We present 2 clinical case examples and specify interpretative guidelines for MSIA that integrate multiple circumplex profiles (e.g., problems, traits, sensitivities, strengths, values, and efficacies) for each patient. Subsequently, we demonstrate how this approach provides a context to better understand patient symptoms and difficulties, and discuss how it can inform case conceptualization, treatment planning, and intervention.

It is difficult to determine if, or when, individuals with stroke are ready to undergo on-road fitness-to-drive assessment. The Occupational Therapy - Driver Off Road Assessment Battery was developed to determine client suitability to resume driving. The predictive validity of the Battery needs to be verified for people with stroke. Examine the predictive validity of the Occupational Therapy - Driver Off Road Assessment Battery for on-road performance among people with stroke. Off-road data were collected from 148 people post stroke on the Battery and the outcome of their on-road assessment was recorded as: fit-to-drive or not fit-to-drive. The majority of participants (76%) were able to resume driving. A classification and regression tree (CART) analysis using four subtests (three cognitive and one physical) from the Battery demonstrated an area under the curve (AUC) of 0.8311. Using a threshold of 0.5, the model correctly predicted 98/112 fit-to-drive (87.5%) and 26/36 people not fit-to-drive (72.2%). The three cognitive subtests from the Occupational Therapy - Driver Off Road Assessment Battery and potentially one of the physical tests have good predictive validity for client fitness-to-drive. These tests can be used to screen client suitability for proceeding to an on-road test following stroke. Implications for Rehabilitation: Following stroke, drivers should be counseled (including consideration of local legislation) concerning return to driving. The Occupational Therapy - Driver Off Road Assessment Battery can be used in the clinic to screen people for suitability to undertake on road assessment. Scores on four of the Occupational Therapy - Driver Off Road Assessment Battery subtests are predictive of resumption of driving following stroke.

2012-01-01

Assessment of software nonfunctional properties (NFP) is an important problem in software development. In the context of model-driven development, an emerging approach for the analysis of different NFPs consists of the following steps: (a) to extend the software models with annotations describing the NFP of interest; (b) to transform automatically the annotated software model to the formalism chosen for NFP analysis; (c) to analyze the formal model using existing solvers; (d) to assess the software based on the results and give feedback to designers. Such a modeling→analysis→assessment approach can be applied to any software modeling language, be it general purpose or domain specific. In this paper, we focus on UML-based development and on the dependability NFP, which encompasses reliability, availability, safety, integrity, and maintainability. The paper presents the profile used to extend UML with dependability information, the model transformation to generate a DSPN formal model, and the assessment of the system properties based on the DSPN results.

Iron overload (IOL) due to increased intestinal iron absorption constitutes a major clinical problem in patients with non-transfusion-dependent thalassemia (NTDT), which is a cumulative process with advancing age. Current models for iron metabolism in patients with NTDT suggest that suppression of serum hepcidin leads to an increase in iron absorption and subsequent release of iron from the reticuloendothelial system, leading to depletion of macrophage iron, relatively low levels of serum ferritin, and liver iron loading. The consequences of IOL in patients with NTDT are multiple and multifactorial. Accurate and reliable methods of diagnosis and monitoring of body iron levels are essential, and the method of choice for measuring iron accumulation will depend on the patient's needs and on the available facilities. Iron chelation therapy (ICT) remains the backbone of NTDT management and is one of the most effective and practical ways of decreasing morbidity and mortality. The aim of this review is to describe the mechanism of IOL in NTDT, and the clinical complications that can develop as a result, in addition to the current and future therapeutic options available for the management of IOL in NTDT.

This study assessed the psychopathological effects of participation in a 10-session horticultural therapy program in patients with schizophrenia. The study design was pre and post test design of experimental and control groups. Twenty-eight Korean patients with schizophrenia, recruited from a mental health clinic and two mental health rehabilitation centers in Suwon, South Korea, were voluntarily assigned to either a control group (average age: 33.4±9.4years) or a horticultural therapy group (average age: 42.1±13.0years). The participants in the horticultural therapy group participated in a 10-session horticultural therapy program designed around various plant cultivating activities. The horticultural therapy program involved sessions once a week from April 2017 to June 2017. A psychiatrist evaluated the psychopathological symptoms of schizophrenic patients in both groups. To assess the clinical psychopathological effects, the Korean version of the Positive and Negative Syndrome Scale (PANSS) and Brief Psychiatric Rating Scale (BPRS) were used. The horticultural therapy group significantly improved in terms of positive, negative, and general symptoms on the PANSS after the 10-session horticultural therapy program. Moreover, the horticultural therapy group significantly improved in terms of clinical symptoms of schizophrenia in BPRS after the 10-session horticultural therapy program. However, there was no change in the PANSS and BPRS scores in the control group. This study showed the potential of horticultural therapy in improving psychopathological symptoms in psychiatric patients. Future studies should investigate the effects of long-term horticultural therapy program on the chronic symptoms of patients with schizophrenia. Copyright © 2017 Elsevier Ltd. All rights reserved.

Individual scale characteristics and the inventory structure of the Personality Assessment Inventory (PAI; Morey, 1991) were examined by conducting internal consistency and factor analyses of item and scale score data from a large group (N = 301) of alcohol-dependent patients. Alpha coefficients, mean inter-item correlations, and corrected item-total scale correlations for the sample paralleled values reported by Morey for a large clinical sample. Minor differences in the scale factor structure of the inventory from Morey's clinical sample were found. Overall, the findings support the use of the PAI in the assessment of personality and psychopathology of alcohol-dependent patients.

Abstract Rationale: Intestinal lymphangiectasia (IL) is a rare enteropathy involving the expansion and rupture of intestinal lymphatic channels. Although several reports have studied cases of primary IL (PIL), this condition is very rare, and is even less commonly encountered in infants. This study aimed to investigate the nutritional therapy and effect assessment of chylous reflux disorder caused by PIL in infants. Patient concerns: Infantile patients were enrolled in the Affiliated Beijing Shijitan Hospital of the Capital Medical University between January 2012 and March 2014. The minimum age of onset was 4 months and the maximum age of onset was 16 months, with an average age of 4.9 months. Diagnoses: All children were inpatient who had been diagnosed with chylous reflux syndrome (chylothorax and/or chylic abdomen) caused by PIL. Interventions: Retrospective analysis and individualized nutrition therapy of these cases were carried out. Finally, nutritional therapy and prognosis of PIL were assessed and summarized. Outcomes: All the children survived, showed improvement in the serum total protein, albumin, and HGB levels after nutritional therapy. After comprehensive nutritional therapy, we were able to achieve diarrhea control for all the 9 patients, and after treatment, the children passed soft, yellow stools 1 to 2 times/d. After treatment, the height and weight of all patients increased to within the normal ranges of the World Health Organization standard chart. The mean serum albumin level reached 41.3 g/L. All nutrition-related indicators were found to have significant improvement compared with the baseline levels. Lessons: The results revealed that nutritional therapy for the 9 children with PIL was effective, and it may be able to improve the clinical syndromes and symptoms of children with PIL and promote recovery.

The current lack of pharmacological treatments for cannabis use disorder (CUD) warrants novel approaches and further investigation of promising pharmacotherapy. We previously showed that nabiximols (27 mg/ml Δ9-tetrahydrocannabinol (THC)/ 25 mg/ml cannabidiol (CBD), Sativex®) can decrease cannabis withdrawal symptoms. Here, we assessed in a pilot study the tolerability and safety of self-titrated nabiximols vs. placebo among 40 treatment-seeking cannabis-dependent participants. Subjects participated in a double blind randomized clinical trial, with as-needed nabiximols up to 113.4 mg THC/105 mg CBD or placebo daily for 12 weeks, concurrently with Motivational Enhancement Therapy and Cognitive Behavioral Therapy (MET/CBT). Primary outcome measures were tolerability and abstinence, secondary outcome measures were days and amount of cannabis use, withdrawal, and craving scores. Participants received up to CDN$ 855 in compensation for their time. Medication was well tolerated and no serious adverse events (SAEs) were observed. Rates of adverse events did not differ between treatment arms (F1,39 = 0.205, NS). There was no significant change in abstinence rates at trial end. Participants were not able to differentiate between subjective effects associated with nabiximols or placebo treatments (F1,40 = 0.585, NS). Cannabis use was reduced in the nabiximols (70.5%) and placebo groups (42.6%). Nabiximols reduced cannabis craving but no significant differences between the nabiximols and placebo groups were observed on withdrawal scores. Nabiximols in combination with MET/CBT was well tolerated and allowed for reduction of cannabis use. Future clinical trials should explore the potential of high doses of nabiximols for cannabis dependence.

Chen, Kelly Yan; Chen, Lucy; Mao, Jianren

2014-05-01

Buprenorphine-naloxone (bup/nal in 4:1 ratio; Suboxone; Reckitt Benckiser Pharmaceuticals Incorporation, Richmond, VA) is approved by the Food and Drug Administration for outpatient office-based addiction treatment. In the past few years, bup/nal has been increasingly prescribed off-label for chronic pain management. The current data suggest that bup/nal may provide pain relief in patients with chronic pain with opioid dependence or addiction. However, the unique pharmacological profile of bup/nal confers it to be a weak analgesic that is unlikely to provide adequate pain relief for patients without opioid dependence or addiction. Possible mechanisms of pain relief by bup/nal therapy in opioid-dependent patients with chronic pain may include reversal of opioid-induced hyperalgesia and improvement in opioid tolerance and addiction. Additional studies are needed to assess the implication of bup/nal therapy in clinical anesthesia and perioperative pain management.

To verify whether the subjectively and objectively assessed patient's skills in applying compression therapy constitute a predicting factor of venous ulcer recurrence. Systematic implementation of compression therapy by the patient is a core of prophylaxis for recurrent ulcers. Therefore, patient education constitutes a significant element of care. However, controversies remain if all individuals benefit equally from education. A retrospective analysis. The study included medical records of patients with venous ulcers (n = 351) treated between 2001 and 2011 at the Clinic for Chronic Wounds at Bydgoszcz Clinical Hospital. We compared two groups of patients, (1) with at least one episode of recurrent ulcer during the five-year observation period, and (2) without recurrences throughout the analysed period in terms of their theoretical skills and knowledge on compression therapy recorded at baseline and after one month. Very good self-assessment of a patient's compression therapy skills and weak assessment of these skills by a nurse proved significant risk factors for recurrence of the ulcers on univariate analysis. The significance of these variables as independent risk factors for recurrent ulcers has been also confirmed on multivariate analysis, which also took into account other clinical parameters. Building up proper compression therapy skills among the patients should be the key element of a properly construed nurse-based prophylactic program, as it is the most significant modifiable risk factor for recurrent ulcers. Although the development of compression skills is undeniably important, also other factors should be considered, e.g. surgical correction of superficial reflux. Instruction on compression therapy should be conducted by properly trained nursing personnel - the nurses should have received both content and psychological training. The compression therapy training should contain practical instruction with guided exercises and in-depth objective

2001-01-01

Aim: The change of both amount and chemical forms of radioiodine exhaled in the air of rooms with patients on the therapy ward should be investigated depending on radioactivity applied, time after application, and kind of thyroid disease. Methods: The air of ward-rooms of 62 patients with thyroid carcinoma, Graves' Disease, and autonomy which received different therapy doses, was investigated with an portable constant air flow sampler. Different chemical iodine species (organic, elemental, aerosol bound) were collected during 8 hr in various filters until 3 days after application of the radioiodine capsule, according to their chemical form. The radioactivity in the filters was measured with a well counter on defined time points after application. Results: The radioactivity exhaled was between 0,008 and 0,03% related to activity of radioiodine applied. The percentage of radioiodine exhaled related to the activity applied, differed significantly depending on disease and changed as follows: Grave's disease > autonomy > carcinoma. The exhalation of radioiodine became stronger with increasing applied activities and showed an exponential decrease with time. The most part of radioiodine was present in organic bound form. This organic portion decreased with time in favour of the other iodine species. Conclusion: The degree of accumulation of radioiodine orally applied within thyroid seems to be in direct proportion to the extend of its exhalation. Further measurements directly in the breathing air of RIT-patients are necessary, in order to clarify the relationship between degree of thyroid uptake and quantity as well as chemical form of radioiodine exhaled.

Improve the quantity and quality of information obtained from traditional Loewenstein Occupational Therapy Cognitive Assessment Battery systems to monitor the evolution of patients' rehabilitation process as well as to compare different rehabilitation therapies. The system replaces traditional artefacts with virtual versions of them to take advantage of cutting edge interaction technology. The system is defined as a Distributed User Interface (DUI) supported by a display ecosystem, including mobile devices as well as multi-touch surfaces. Due to the heterogeneity of the devices involved in the system, the software technology is based on a client-server architecture using the Web as the software platform. The system provides therapists with information that is not available (or it is very difficult to gather) using traditional technologies (i.e. response time measurements, object tracking, information storage and retrieval facilities, etc.). The use of DUIs allows therapists to gather information that is unavailable using traditional assessment methods as well as adapt the system to patients' profile to increase the range of patients that are able to take this assessment. Implications for Rehabilitation Using a Distributed User Interface environment to carry out LOTCAs improves the quality of the information gathered during the rehabilitation assessment. This system captures physical data regarding patient's interaction during the assessment to improve the rehabilitation process analysis. Allows professionals to adapt the assessment procedure to create different versions according to patients' profile. Improves the availability of patients' profile information to therapists to adapt the assessment procedure.

Assessment of adherence to visual correction and occlusion therapy in the Infant Aphakia Treatment Study

Full Text Available Occlusion therapy throughout early childhood is believed to be efficacious in treating deprivation amblyopia but has not been rigorously assessed in clinical trials. Further, tools to assess adherence to such therapy over an extended period of time are lacking. Using data from the Infant Aphakia Treatment Study, a randomized clinical trial of treatment for unilateral congenital cataract, we examined the use of quarterly 48-h recall interviews and annual 7-day prospective diaries to assess reported hours of patching in 114 children throughout the first 5 years of life. Consistency of data reported was assessed using correlation coefficients and intraclass correlation coefficients. Both interview and diary data showed excellent consistency with Cronbach’s Alpha’s ranging from 0.69 to 0.88 for hours of patching and 0.60 to 0.73 for hours of sleep. However, caregivers reported somewhat more adherence in prospective diaries than retrospective interviews. Completion rates, on the other hand, were substantially higher for telephone interviews than prospective diaries. For example, four years after surgery response rates to telephone interviews exceeded 75% versus completion rates of only 54% for diaries. In situations where occlusion dose monitors cannot be used for assessing adherence to occlusion therapy, such as in infants or over an extended period of time, quantitative assessments of occlusion therapy can be obtained by parental report, either as a series of prospective diaries or a series of recall interviews.

Acute toxicity in comprehensive head and neck radiation for nasopharynx and paranasal sinus cancers: cohort comparison of 3D conformal proton therapy and intensity modulated radiation therapy

To evaluate acute toxicity endpoints in a cohort of patients receiving head and neck radiation with proton therapy or intensity modulated radiation therapy (IMRT). Forty patients received comprehensive head and neck radiation including bilateral cervical nodal radiation, given with or without chemotherapy, for tumors of the nasopharynx, nasal cavity or paranasal sinuses, any T stage, N0-2. Fourteen received comprehensive treatment with proton therapy, and 26 were treated with IMRT, either comprehensively or matched to proton therapy delivered to the primary tumor site. Toxicity endpoints assessed included g-tube dependence at the completion of radiation and at 3 months after radiation, opioid pain medication requirement compared to pretreatment normalized as equivalent morphine dose (EMD) at completion of treatment, and at 1 and 3 months after radiation. In a multivariable model including confounding variables of concurrent chemotherapy and involved nodal disease, comprehensive head and neck radiation therapy using proton therapy was associated with a lower opioid pain requirement at the completion of radiation and a lower rate of gastrostomy tube dependence by the completion of radiation therapy and at 3 months after radiation compared to IMRT. Proton therapy was associated with statistically significant lower mean doses to the oral cavity, esophagus, larynx, and parotid glands. In subgroup analysis of 32 patients receiving concurrent chemotherapy, there was a statistically significant correlation with a greater opioid pain medication requirement at the completion of radiation and both increasing mean dose to the oral cavity and to the esophagus. Proton therapy was associated with significantly reduced radiation dose to assessed non-target normal tissues and a reduced rate of gastrostomy tube dependence and opioid pain medication requirements. This warrants further evaluation in larger studies, ideally with patient-reported toxicity outcomes and quality of life

2016-01-01

Case studies of people with Huntington's disease (HD) report that music therapy provides a range of benefits that may improve quality of life; however, no robust music therapy assessment tools exist for this population. Develop and conduct preliminary psychometric testing of a music therapy assessment tool for patients with advanced HD. First, we established content and face validity of the Music Therapy Assessment Tool for Advanced HD (MATA-HD) through focus groups and field testing. Second, we examined psychometric properties of the resulting MATA-HD in terms of its construct validity, internal consistency, and inter-rater and intra-rater reliability over 10 group music therapy sessions with 19 patients. The resulting MATA-HD included a total of 15 items across six subscales (Arousal/Attention, Physical Presentation, Communication, Musical, Cognition, and Psychological/Behavioral). We found good construct validity (r ≥ 0.7) for Mood, Communication Level, Communication Effectiveness, Choice, Social Behavior, Arousal, and Attention items. Cronbach's α of 0.825 indicated good internal consistency across 11 items with a common focus of engagement in therapy. The inter-rater reliability (IRR) Intra-Class Coefficient (ICC) scores averaged 0.65, and a mean intra-rater ICC reliability of 0.68 was obtained. Further training and retesting provided a mean of IRR ICC of 0.7. Preliminary data indicate that the MATA-HD is a promising tool for measuring patient responses to music therapy interventions across psychological, physical, social, and communication domains of functioning in patients with advanced HD. © the American Music Therapy Association 2016.

An audit about music therapy assessments and recommendations for adult patients suspected to be in a low awareness state.

Science.gov (United States)

Daveson, Barbara

2010-01-01

In neuro-rehabilitation, the role of music therapy is expanding to include assessment of patients with severely-altered states of consciousness. Diagnosis of these conditions is a complex task for all, and cases of misdiagnosis have been reported. Aggregated findings from 33 music therapy assessments of patients suspected of being in a low awareness state are described and discussed here. The Music Therapy Assessment Tool for Low Awareness States (MATLAS) was used during these assessments. All assessments were offered as part of a specialist multidisciplinary assessment package. A brief description of the patient group is supplied, along with details regarding the assessment tool and the recommendations that followed. In summary, a difference in the time it took to assess patients in vegetative state (VS) as compared to those in minimally conscious state (MCS) was found and, on average, the assessment of those in VS took less time to complete than for those in MCS. A greater range in session length was found for patients in VS, as compared to those in MCS. Generally after the assessments, patients in VS were likely to be admitted to a sensory regulation group administered by a music therapy assistant, supervised by a qualified music therapist, to enable the continued collection of behavioral responses to stimuli. Patients in MCS were admitted to a music therapy treatment program offered by a qualified music therapist. Ongoing work is recommended to advance the assessment and treatment of this patient population, and to consolidate the role of music therapy with this population.

Assessing Patients’ Cognitive Therapy Skills: Initial Evaluation of the Competencies of Cognitive Therapy Scale

Strunk, Daniel R.; Hollars, Shannon N.; Adler, Abby D.; Goldstein, Lizabeth A.; Braun, Justin D.

2014-01-01

In Cognitive Therapy (CT), therapists work to help patients develop skills to cope with negative affect. Most current methods of assessing patients’ skills are cumbersome and impractical for clinical use. To address this issue, we developed and conducted an initial psychometric evaluation of self and therapist reported versions of a new measure of CT skills: the Competencies of Cognitive Therapy Scale (CCTS). We evaluated the CCTS at intake and post-treatment in a sample of 67 patients participating in CT. The CCTS correlated with a preexisting measure of CT skills (the Ways of Responding Questionnaire) and was also related to concurrent depressive symptoms. Across CT, self-reported improvements in CT competencies were associated with greater changes in depressive symptoms. These findings offer initial evidence for the validity of the CCTS. We discuss the CCTS in comparison with other measures of CT skills and suggest future research directions. PMID:25408560

Full Text Available Abstract Background In The Netherlands, helmet therapy is a commonly used treatment in infants with skull deformation (deformational plagiocephaly or deformational brachycephaly. However, evidence of the effectiveness of this treatment remains lacking. The HEADS study (HElmet therapy Assessment in Deformed Skulls aims to determine the effects and costs of helmet therapy compared to no helmet therapy in infants with moderate to severe skull deformation. Methods/design Pragmatic randomised controlled trial (RCT nested in a cohort study. The cohort study included infants with a positional preference and/or skull deformation at two to four months (first assessment. At 5 months of age, all children were assessed again and infants meeting the criteria for helmet therapy were asked to participate in the RCT. Participants were randomly allocated to either helmet therapy or no helmet therapy. Parents of eligible infants that do not agree with enrolment in the RCT were invited to stay enrolled for follow up in a non-randomisedrandomised controlled trial (nRCT; they were then free to make the decision to start helmet therapy or not. Follow-up assessments took place at 8, 12 and 24 months of age. The main outcome will be head shape at 24 months that is measured using plagiocephalometry. Secondary outcomes will be satisfaction of parents and professionals with the appearance of the child, parental concerns about the future, anxiety level and satisfaction with the treatment, motor development and quality of life of the infant. Finally, compliance and costs will also be determined. Discussion HEADS will be the first study presenting data from an RCT on the effectiveness of helmet therapy. Outcomes will be important for affected children and their parents, health care professionals and future treatment policies. Our findings are likely to influence the reimbursement policies of health insurance companies. Besides these health outcomes, we will be able to

While PET with non-FDG tracers (mainly choline and Ga-PSMA) has commonly been used for restaging in men with biochemically recurrent prostate cancer, as well as for primary staging, it is only recently that a few preliminary studies have addressed the possible use of PET for monitoring the response to systemic therapy of metastatic disease, especially innovative treatments such as abiraterone and enzalutamide. This article aims to evaluate the role of PET imaging with different non-FDG radiotracers for assessment of therapy in advanced prostate cancer patients. (orig.)

SU-F-J-178: A Computer Simulation Model Observer for Task-Based Image Quality Assessment in Radiation Therapy

International Nuclear Information System (INIS)

Dolly, S; Mutic, S; Anastasio, M; Li, H; Yu, L

2016-01-01

Purpose: Traditionally, image quality in radiation therapy is assessed subjectively or by utilizing physically-based metrics. Some model observers exist for task-based medical image quality assessment, but almost exclusively for diagnostic imaging tasks. As opposed to disease diagnosis, the task for image observers in radiation therapy is to utilize the available images to design and deliver a radiation dose which maximizes patient disease control while minimizing normal tissue damage. The purpose of this study was to design and implement a new computer simulation model observer to enable task-based image quality assessment in radiation therapy. Methods: A modular computer simulation framework was developed to resemble the radiotherapy observer by simulating an end-to-end radiation therapy treatment. Given images and the ground-truth organ boundaries from a numerical phantom as inputs, the framework simulates an external beam radiation therapy treatment and quantifies patient treatment outcomes using the previously defined therapeutic operating characteristic (TOC) curve. As a preliminary demonstration, TOC curves were calculated for various CT acquisition and reconstruction parameters, with the goal of assessing and optimizing simulation CT image quality for radiation therapy. Sources of randomness and bias within the system were analyzed. Results: The relationship between CT imaging dose and patient treatment outcome was objectively quantified in terms of a singular value, the area under the TOC (AUTOC) curve. The AUTOC decreases more rapidly for low-dose imaging protocols. AUTOC variation introduced by the dose optimization algorithm was approximately 0.02%, at the 95% confidence interval. Conclusion: A model observer has been developed and implemented to assess image quality based on radiation therapy treatment efficacy. It enables objective determination of appropriate imaging parameter values (e.g. imaging dose). Framework flexibility allows for incorporation

2010-01-01

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

This session will focus on quantitative imaging for assessment of tumor response to radiation therapy. This is a technically challenging method to translate to practice in radiation therapy. In the new era of precision medicine, however, delivering the right treatment, to the right patient, and at the right time, can positively impact treatment choices and patient outcomes. Quantitative imaging provides the spatial sensitivity required by radiation therapy for precision medicine that is not available by other means. In this Joint ESTRO -AAPM Symposium, three leading-edge investigators will present specific motivations for quantitative imaging biomarkers in radiation therapy of esophageal, head and neck, locally advanced non-small cell lung cancer, and hepatocellular carcinoma. Experiences with the use of dynamic contrast enhanced (DCE) MRI, diffusion- weighted (DW) MRI, PET/CT, and SPECT/CT will be presented. Issues covered will include: response prediction, dose-painting, timing between therapy and imaging, within-therapy biomarkers, confounding effects, normal tissue sparing, dose-response modeling, and association with clinical biomarkers and outcomes. Current information will be presented from investigational studies and clinical practice. Learning Objectives: Learn motivations for the use of quantitative imaging biomarkers for assessment of response to radiation therapy Review the potential areas of application in cancer therapy Examine the challenges for translation, including imaging confounds and paucity of evidence to date Compare exemplary examples of the current state of the art in DCE-MRI, DW-MRI, PET/CT and SPECT/CT imaging for assessment of response to radiation therapy Van der Heide: Research grants from the Dutch Cancer Society and the European Union (FP7) Bowen: RSNA Scholar grant

2014-06-01

Full Text Available Background: Breast cancer affects over one million women annually and is the most common global malignancy among women. Extensive improvements have taken place in the management of breast cancer in recent years and a higher percentage of women are cured from this disease. A proper assessment of the quality of life of women with breast cancer is an essential component in disease management. The Functional Assessment of Cancer Therapy- Breast Symptom Index has been commonly used and well-validated among English speaking populations as well as other populations. To date, no formal translation and evaluation of the Functional Assessment of Cancer Therapy-Breast System Index exists in Arabic. Therefore, this study intends to translate, adapt and face-validate the Functional Assessment of Cancer Therapy-Breast System Index into Arabic, specifically in the context of the Lebanese culture. Methods: We conducted forward and backward translation in Arabic, combined with face validity by clinicians. This was followed by pre-testing to ensure the instrument’s adequacy and cultural sensitivity conducted by the administration of face-to-face interviews with individual breast cancer patients (n=33 and two focus groups (4 women/group to evaluate the relevance and appropriateness of each item and words used in the questionnaire. Results: Study results reinforced the value of the Arabic translated version of the Functional Assessment of Cancer Therapy-Breast System Index in capturing the quality of life of women with breast cancer in Lebanon. Conclusion: The instrument was perceived to be adequate, appropriate for use, culturally sensitive, simple as well as exhaustive. Suggestions have been made to enrich the instruments’ ability to incorporate other quality of life dimensions not captured, as well to enhance the cultural specificity of the Functional Assessment of Cancer Therapy-Breast System Index, when administered among Lebanese women diagnosed with

Evidential analytic hierarchy process dependence assessment methodology in human reliability analysis

International Nuclear Information System (INIS)

Chen, Lu Yuan; Zhou, Xinyi; Xiao, Fuyuan; Deng, Yong; Mahadevan, Sankaran

2017-01-01

In human reliability analysis, dependence assessment is an important issue in risky large complex systems, such as operation of a nuclear power plant. Many existing methods depend on an expert's judgment, which contributes to the subjectivity and restrictions of results.

Complement inhibitors expressed on tumor cells provide an evasion mechanism against mAb therapy and may modulate the development of an acquired antitumor immune response. Here we investigate a strategy to amplify mAb-targeted complement activation on a tumor cell, independent of a requirement to target and block complement inhibitor expression or function, which is difficult to achieve in vivo. We constructed a murine fusion protein, CR2Fc, and demonstrated that the protein targets to C3 activation products deposited on a tumor cell by a specific mAb, and amplifies mAb-dependent complement activation and tumor cell lysis in vitro. In syngeneic models of metastatic lymphoma (EL4) and melanoma (B16), CR2Fc significantly enhanced the outcome of mAb therapy. Subsequent studies using the EL4 model with various genetically modified mice and macrophage-depleted mice revealed that CR2Fc enhanced the therapeutic effect of mAb therapy via both macrophage-dependent FcγR-mediated antibody-dependent cellular cytotoxicity, and by direct complement-mediated lysis. Complement activation products can also modulate adaptive immunity, but we found no evidence that either mAb or CR2Fc treatment had any effect on an antitumor humoral or cellular immune response. CR2Fc represents a potential adjuvant treatment to increase the effectiveness of mAb therapy of cancer. PMID:22442351

[An assessment of tinnitus retraining therapy].

Based on the neurophysiological model of tinnitus developed by Jastreboff and Hazell [39] there have been some important developments in understanding and therapy of tinnitus over the last decade. The clinical applications of this model are known as "tinnitus retraining therapy", which has the objective of reducing both the distress associated with tinnitus and the tinnitus perception itself. As a form of systematic, repeated and skilled counselling over a long period of up to 2 years supported by sound therapy (hearing aid or noise generator) the evidence for their high degree of effectiveness is overwhelming. On the basis of a "German concept" of tinnitus retraining therapy developed and proposed by the ADANO (Arbeitsgemeinschaft deutschsprachiger Audiologen und Neurootologen) the current status of this treatment will be briefly reviewed including some actual studies of Goebel et al. [14] that confirm the world wide critical comments on the recent developments in the management of tinnitus especially with regard to tinnitus retraining therapy [79].

It has recently been suggested that pro-tumorigenic host-mediated processes induced in response to chemotherapy counteract the anti-tumor activity of therapy, and thereby decrease net therapeutic outcome. Here we use experimental data to formulate a mathematical model describing the host response to different doses of paclitaxel (PTX) chemotherapy as well as the duration of the response. Three previously described host-mediated effects are used as readouts for the host response to therapy. These include the levels of circulating endothelial progenitor cells in peripheral blood and the effect of plasma derived from PTX-treated mice on migratory and invasive properties of tumor cells in vitro . A first set of mathematical models, based on basic principles of pharmacokinetics/pharmacodynamics, did not appropriately describe the dose-dependence and duration of the host response regarding the effects on invasion. We therefore provide an alternative mathematical model with a dose-dependent threshold, instead of a concentration-dependent one, that describes better the data. This model is integrated into a global model defining all three host-mediated effects. It not only precisely describes the data, but also correctly predicts host-mediated effects at different doses as well as the duration of the host response. This mathematical model may serve as a tool to predict the host response to chemotherapy in cancer patients, and therefore may be used to design chemotherapy regimens with improved therapeutic outcome by minimizing host mediated effects.

The aim of this study was to assess the level of tobacco dependence education offered by Italian dental hygiene programs. A fifty-question survey was mailed to the thirty-one active public and private dental hygiene programs in Italy during the 2008-09 academic year. The survey assessed faculty confidence in teaching tobacco treatment, which courses contained tobacco dependence content, the number of minutes spent on specific content areas, and the level of clinical competence that dental hygiene graduates should be able to demonstrate. Surveys were returned by sixteen programs for a response rate of 52 percent. Respondents indicated tobacco dependence education was included in clinic or clinic seminar (56 percent), periodontics (44 percent), oral pathology (31 percent), and prevention (19 percent). All programs reported including the effects of tobacco on general and oral diseases in courses. However, more in-depth topics received less curriculum time; these included tobacco treatment strategies (63 percent) and discussion of cessation medications (31 percent). Interestingly, 62 percent of the respondents indicated they expected dental hygiene graduates to demonstrate a tobacco treatment competency level of a moderate intervention or higher (counseling, discussion of medications, follow-up) rather than a brief intervention in which patients are advised to quit then referred to a quitline. The results of this study indicated that Italian dental hygiene students are not currently receiving adequate instruction in tobacco treatment techniques nor are they being adequately assessed. This unique overview of Italian dental hygiene tobacco dependence education provides a basis for further discussion towards a national competency-based curriculum.

Addressing dependability by applying an approach for model-based risk assessment

This paper describes how an approach for model-based risk assessment (MBRA) can be applied for addressing different dependability factors in a critical application. Dependability factors, such as availability, reliability, safety and security, are important when assessing the dependability degree of total systems involving digital instrumentation and control (I and C) sub-systems. In order to identify risk sources their roles with regard to intentional system aspects such as system functions, component behaviours and intercommunications must be clarified. Traditional risk assessment is based on fault or risk models of the system. In contrast to this, MBRA utilizes success-oriented models describing all intended system aspects, including functional, operational and organizational aspects of the target. The EU-funded CORAS project developed a tool-supported methodology for the application of MBRA in security-critical systems. The methodology has been tried out within the telemedicine and e-commerce areas, and provided through a series of seven trials a sound basis for risk assessments. In this paper the results from the CORAS project are presented, and it is discussed how the approach for applying MBRA meets the needs of a risk-informed Man-Technology-Organization (MTO) model, and how methodology can be applied as a part of a trust case development

2012-07-01

Full Text Available Abstract Background Objective techniques to assess the amelioration of vision in patients with impaired visual function are needed to standardize efficacy assessment in gene therapy trials for ocular diseases. Pupillometry has been investigated in several diseases in order to provide objective information about the visual reflex pathway and has been adopted to quantify visual impairment in patients with Leber Congenital Amaurosis (LCA. In this paper, we describe detailed methods of pupillometric analysis and a case study on three Italian patients affected by Leber Congenital Amaurosis (LCA involved in a gene therapy clinical trial at two follow-up time-points: 1 year and 3 years after therapy administration. Methods Pupillary light reflexes (PLR were measured in patients who had received a unilateral subretinal injection in a clinical gene therapy trial. Pupil images were recorded simultaneously in both eyes with a commercial pupillometer and related software. A program was generated with MATLAB software in order to enable enhanced pupil detection with revision of the acquired images (correcting aberrations due to the inability of these severely visually impaired patients to fixate, and computation of the pupillometric parameters for each stimulus. Pupil detection was performed through Hough Transform and a non-parametric paired statistical test was adopted for comparison. Results The developed program provided correct pupil detection also for frames in which the pupil is not totally visible. Moreover, it provided an automatic computation of the pupillometric parameters for each stimulus and enabled semi-automatic revision of computerized detection, eliminating the need for the user to manually check frame by frame. With reference to the case study, the amplitude of pupillary constriction and the constriction velocity were increased in the right (treated eye compared to the left (untreated eye at both follow-up time-points, showing stability of

The introduction of targeted agents for the treatment of renal cell carcinoma (RCC) has resulted in new challenges for assessing response to therapy, and conventional response criteria using computed tomography (CT) are limited. It is widely recognised that targeted therapies may lead to significant necrosis without significant reduction in tumour size. In addition, the vascular effects of antiangiogenic therapy may occur long before there is any reduction in tumour size. To perform a systematic review of conventional and novel imaging methods for the assessment of response to targeted agents in RCC and to discuss their use from a clinical perspective. Relevant databases covering the period January 2006 to April 2013 were searched for studies reporting on the use of anatomic and functional imaging techniques to predict response to targeted therapy in RCC. Inclusion criteria were randomised trials, nonrandomised controlled studies, retrospective case series, and cohort studies. Reviews, animal and preclinical studies, case reports, and commentaries were excluded. A narrative synthesis of the evidence is presented. A total of 331 abstracts and 76 full-text articles were assessed; 34 studies met the inclusion criteria. Current methods of response assessment in RCC include anatomic methods--based on various criteria including Choi, size and attenuation CT, and morphology, attenuation, size, and structure--and functional techniques including dynamic contrast-enhanced (DCE) CT, DCE-magnetic resonance imaging, DCE-ultrasonography, positron emission tomography, and approaches utilising radiolabelled monoclonal antibodies. Functional imaging techniques are promising surrogate biomarkers of response in RCC and may be more appropriate than anatomic CT-based methods. By enabling quantification of tumour vascularisation, functional techniques can directly and rapidly detect the biologic effects of antiangiogenic therapies compared with the indirect detection of belated effects

Intestinal lymphangiectasia (IL) is a rare enteropathy involving the expansion and rupture of intestinal lymphatic channels. Although several reports have studied cases of primary IL (PIL), this condition is very rare, and is even less commonly encountered in infants. This study aimed to investigate the nutritional therapy and effect assessment of chylous reflux disorder caused by PIL in infants. Infantile patients were enrolled in the Affiliated Beijing Shijitan Hospital of the Capital Medical University between January 2012 and March 2014. The minimum age of onset was 4 months and the maximum age of onset was 16 months, with an average age of 4.9 months. All children were inpatient who had been diagnosed with chylous reflux syndrome (chylothorax and/or chylic abdomen) caused by PIL. Retrospective analysis and individualized nutrition therapy of these cases were carried out. Finally, nutritional therapy and prognosis of PIL were assessed and summarized. All the children survived, showed improvement in the serum total protein, albumin, and HGB levels after nutritional therapy. After comprehensive nutritional therapy, we were able to achieve diarrhea control for all the 9 patients, and after treatment, the children passed soft, yellow stools 1 to 2 times/d. After treatment, the height and weight of all patients increased to within the normal ranges of the World Health Organization standard chart. The mean serum albumin level reached 41.3 g/L. All nutrition-related indicators were found to have significant improvement compared with the baseline levels. The results revealed that nutritional therapy for the 9 children with PIL was effective, and it may be able to improve the clinical syndromes and symptoms of children with PIL and promote recovery.

Assessing client self-narrative change in emotion-focused therapy of depression: an intensive single case analysis.

Science.gov (United States)

Angus, Lynne E; Kagan, Fern

2013-12-01

Personality researchers use the term self-narrative to refer to the development of an overall life story that places life events in a temporal sequence and organizes them in accordance to overarching themes. In turn, it is often the case that clients seek out psychotherapy when they can no longer make sense of their life experiences, as a coherent story. Angus and Greenberg (L. Angus and L. Greenberg, 2011, Working with narrative in emotion-focused therapy: Changing stories, healing lives. Washington, DC: American Psychological Association Press) view the articulation and consolidation of an emotionally integrated self-narrative account as an important part of the therapeutic change process that is essential for sustained change in emotion-focused therapy of depression. The purpose of the present study was to investigate client experiences of change, and self-narrative reconstruction, in the context of one good outcome emotion-focused therapy dyad drawn from the York II Depression Study. Using the Narrative Assessment Interview (NAI) method, client view of self and experiences of change were assessed at three points in time--after session one, at therapy termination, and at 6 months follow-up. Findings emerging from an intensive narrative theme analyses of the NAI transcripts--and 1 key therapy session identified by the client--are reported and evidence for the contributions of narrative and emotion processes to self-narrative change in emotion-focused therapy of depression are discussed. Finally, the implications of assessing clients' experiences of self-narrative change for psychotherapy research and practice are addressed.

Music therapy in the assessment and treatment of autistic spectrum disorder: clinical application and research evidence.

Science.gov (United States)

Wigram, T; Gold, C

2006-09-01

Children and adolescents with autistic spectrum disorder (ASD) presenting with significant limitations in conventional forms of verbal and non-verbal communication are found to respond positively to music therapy intervention involving both active, improvizational methods and receptive music therapy approaches. Improvizational musical activity with therapeutic objectives and outcomes has been found to facilitate motivation, communication skills and social interaction, as well as sustaining and developing attention. The structure and predictability found in music assist in reciprocal interaction, from which tolerance, flexibility and social engagement to build relationships emerge, relying on a systematic approach to promote appropriate and meaningful interpersonal responses. Published reports of the value and effectiveness of music therapy as an intervention for children with ASD range from controlled studies to clinical case reports. Further documentation has emphasized the role music therapy plays in diagnostic and clinical assessment. Music therapy assessment can identify limitations and weaknesses in children, as well as strengths and potentials. Research evidence from a systematic review found two randomized controlled trials that examined short-term effects of structured music therapy intervention. Significant effects were found in these studies even with extremely small samples, and the findings are important because they demonstrate the potential of the medium of music for autistic children. Case series studies were identified that examined the effects of improvizational music therapy where communicative behaviour, language development, emotional responsiveness, attention span and behavioural control improved over the course of an intervention of improvizational music therapy.

A computational Bayesian approach to dependency assessment in system reliability

International Nuclear Information System (INIS)

Yontay, Petek; Pan, Rong

2016-01-01

Due to the increasing complexity of engineered products, it is of great importance to develop a tool to assess reliability dependencies among components and systems under the uncertainty of system reliability structure. In this paper, a Bayesian network approach is proposed for evaluating the conditional probability of failure within a complex system, using a multilevel system configuration. Coupling with Bayesian inference, the posterior distributions of these conditional probabilities can be estimated by combining failure information and expert opinions at both system and component levels. Three data scenarios are considered in this study, and they demonstrate that, with the quantification of the stochastic relationship of reliability within a system, the dependency structure in system reliability can be gradually revealed by the data collected at different system levels. - Highlights: • A Bayesian network representation of system reliability is presented. • Bayesian inference methods for assessing dependencies in system reliability are developed. • Complete and incomplete data scenarios are discussed. • The proposed approach is able to integrate reliability information from multiple sources at multiple levels of the system.

The availability of adequate instruments for the assessment of nicotine dependence is an important factor that is relevant in the area of tobacco addiction. In this study, we present a Spanish validation of the Nicotine Dependence Syndrome Scale (NDSS) (Shiffman, Waters, & Hickcox, 2004). The sample was composed ofpatients, all daily smokers, who visited their General Practitioner (GP) at five Primary Health Care Centers in different cities of Spain (N = 637). The results indicated adequate reliability for the general factor that assesses nicotine dependence (NDSS-Total) (Cronbach's alpha = .76). Factor analysis confirms the five factors of the original validation: Drive, Continuity, Stereotypy, Priority, and Tolerance. It must be noted that reliability is adequate for the first, and moderate or low for the rest. The NDSS-T and its scales correlate significantly with the Fagerström Test for Nicotine Dependence (FTND), with the nicotine dependence criteria of the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) as assessed through the Structured Clinical Interview for DSM-IV (SCID), with carbon monoxide levels in expired air (CO), and with the number of cigarettes smoked. The ROC curve indicates that the NDSS-T has a score of .79 which is under the curve (.69 for the FTND), thus the prediction of nicotine dependence is adequate. We conclude that this instrument is useful (in terms of its total score NDSS-T) for assessing nicotine dependence for Spanish smokers (in Spain), as has been found in other countries, language groups, and cultures.

Using Evidence Credibility Decay Model for dependence assessment in human reliability analysis

Highlights: • A new computational model is proposed for dependence assessment in HRA. • We combined three factors of “CT”, “TR” and “SP” within Dempster–Shafer theory. • The BBA of “SP” is reconstructed by discounting rate based on the ECDM. • Simulation experiments are illustrated to show the efficiency of the proposed method. - Abstract: Dependence assessment among human errors plays an important role in human reliability analysis. When dependence between two sequent tasks exists in human reliability analysis, if the preceding task fails, the failure probability of the following task is higher than success. Typically, three major factors are considered: “Closeness in Time” (CT), “Task Relatedness” (TR) and “Similarity of Performers” (SP). Assume TR is not changed, both SP and CT influence the degree of dependence level and SP is discounted by the time as the result of combine two factors in this paper. In this paper, a new computational model is proposed based on the Dempster–Shafer Evidence Theory (DSET) and Evidence Credibility Decay Model (ECDM) to assess the dependence between tasks in human reliability analysis. First, the influenced factors among human tasks are identified and the basic belief assignments (BBAs) of each factor are constructed based on expert evaluation. Then, the BBA of SP is discounted as the result of combining two factors and reconstructed by using the ECDM, the factors are integrated into a fused BBA. Finally, the dependence level is calculated based on fused BBA. Experimental results demonstrate that the proposed model not only quantitatively describe the fact that the input factors influence the dependence level, but also exactly show how the dependence level regular changes with different situations of input factors.

This study assesses the use of /sup 81m/Kr scintigraphy as a measurement tool in evaluating the effectiveness of bronchial drainage with percussion and vibration on peripheral ventilation in patients with cystic fibrosis. Ten patients with cystic fibrosis participated. Each patient underwent a /sup 81m/Kr ventilation study and traditional pulmonary function tests. Forty-five minutes later, these studies were repeated before and after a chest physical therapy treatment. Each patient acted as his own control. All /sup 81m/Kr scintiscans were recorded and analyzed visually and numerically using a digital computer to assess distribution of ventilation. Visual analysis of the scintiscans indicated individual variation in treatment response: in some patients ventilation improved with therapy; in others, no change was noted; still others had changes independent of treatment. Numerical data derived from the scintiscans and pulmonary function tests showed no important differences among the three studies of each patient. Airway abnormalities characteristic of cystic fibrosis, progression of the disease, sputum production, or a combination of these factors may account for the individual variation in response to treatment. /sup 81m/Kr scintigraphy is a reliable measure of regional ventilation and should be useful for assessing the efficacy of chest physical therapy because of the consistent, high quality visual data retrieved

Many treatment options are now available for patients with idiopathic pulmonary arterial hypertension (IPAH). Data regarding the optimal combination of therapies are lacking, as is consensus on how to assess response to therapy and when to change therapeutic regimens. To gather the opinions of Canadian pulmonary hypertension (PH) experts regarding standard practice in the care of IPAH patients after therapy is initiated. Canadian PH physicians were surveyed using short questionnaires to assess their opinions and practices in the care of IPAH patients. A Delphi forecasting approach was used to gain consensus among Canadian physicians on the most important clinical parameters to consider when assessing patients after the initiation of therapy. Twenty-six of 37 Canadian PH experts who were invited to participate completed the study. All endorsed the use of combination therapy for IPAH patients despite the lack of universal provincial coverage for this approach. By consensus, WHO functional class, 6 min walk distance and hospitalization for right heart failure were the most important clinical parameters. The most highly rated physical examination parameters were jugular venous pressure, peripheral edema, the presence of ascites and body weight. The overall approach to care of IPAH patients is similar across PH centres in Canada. A limited number of clinical and physical examination parameters were considered to be most important to reassess patients after therapy is initiated. These parameters, along with definition of threshold values, will facilitate the development of standard practice guidelines for IPAH patients in Canada.

Incarcerated people living with HIV and opioid dependence face enormous challenges to accessing evidence-based treatment during incarceration and after release into the community, placing them at risk of poor HIV treatment outcomes, relapse to opioid use and accompanying HIV transmission risk behaviors. Here we describe in detail the design and implementation of Project Harapan, a prospective clinical trial conducted among people living with HIV and opioid dependence who transitioned from prison to the community in Malaysia from 2010 to 2014. This trial involved 2 interventions: within-prison initiation of methadone maintenance therapy and an evidence-based behavioral intervention adapted to the Malaysian context (the Holistic Health Recovery Program for Malaysia, HHRP-M). Individuals were recruited and received the interventions while incarcerated and were followed for 12months after release to assess post-release HIV transmission risk behaviors and a range of other health-related outcomes. Project Harapan was designed as a fully randomized 2×2 factorial trial where individuals would be allocated in equal proportions to methadone maintenance therapy and HHRP-M, methadone maintenance therapy alone, HHRP-M alone, or control. Partway through study implementation, allocation to methadone maintenance therapy was changed from randomization to participant choice; randomization to HHRP-M continued throughout. We describe the justification for this study; the development and implementation of these interventions; changes to the protocol; and screening, enrollment, treatment receipt, and retention of study participants. Logistical, ethical, and analytic issues associated with the implementation of this study are discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

Attentional biases toward substance-related stimuli might play a contributing role in addictive behaviors. This study investigated the selective attention to substance-related stimuli in heroin dependents receiving methadone maintenance therapy. Thirty outpatients receiving methadone maintenance treatment for heroin dependence and 38 healthy controls completed a visual probe task with concurrent eye movement monitoring. The results showed that the heroin group reacted faster to probes associated with substance-related pictures than neutral pictures, and they directed more initial fixations and maintained longer initial fixation durations toward substance-related pictures than neutral pictures. However, attentional bias was not correlated with addiction severity in the heroin group. These findings suggest that attentional bias towards substance-related cues occurs in heroin dependents, although this bias might not be associated with the severity of drug-using behavior.

The ability to estimate the risk of potential reactor accidents is largely determined by the ability to analyze statistically dependent multiple failures. The importance of dependent failures has been indicated in recent probabilistic risk assessment (PRA) studies as well as in reports of reactor operating experiences. This article highlights the importance of several different types of dependent failures from the perspective of the risk and reliability analyst and provides references to the methods and data available for their analysis. In addition to describing the current state of the art, some recent advances, pitfalls, misconceptions, and limitations of some approaches to dependent failure analysis are addressed. A summary is included of the discourse on this subject, which is presented in the Institute of Electrical and Electronics Engineers/American Nuclear Society PRA Procedures Guide

The paper is concerned with immunological evaluation of different stages of combined therapy with local UHF-hyperthermia in children with osteogenic sarcoma. Combined therapy (polychemo- and raditherapy) was shown to cause a decrease in the number of immunocompetent cells, to enhance dysbalance of immunoregulatory T-lymphocytes, to weaken T-lymphocyte function on PHA; immunosuppressive action of combined therapy did not depend on a tumor site. The incorporation of UHF-hyperthermia in the therapeutic scheme weakened the manifestations of secondary immunodeficiency, got back to normal structure of T-lymphocyte population. A favorable immunomodulating effect of hyperthermia was more frequently observed in patients with crural bone tumors. The effect of hyperthermia was revealed after direct influence of thermotherapy but it was absent in continuation of combined treatment

The primary focus of this paper is to describe current trends in pain assessment in end of life care with a secondary focus on music therapy techniques commonly used to address pain for hospice patients. These trends were determined through a survey of 72 board certified music therapists and 92 hospice and palliative nurses. Survey results indicate that most music therapists in the hospice setting incorporate formal pain assessment into their practice; both nursing professionals and music therapists surveyed utilize multiple assessment tools to assess patient pain. Although there are currently a variety of pain assessment tools used, this study indicates that nursing professionals most frequently use the Numerical Rating Scale (NRS) and FACES scales, and identified them as appropriate for use by nonnursing members of the interdisciplinary hospice team. This paper also describes music therapy techniques most often utilized by music therapists with hospice patients to address acute and chronic pain symptoms.

Variants of the Fagerström Tolerance Questionnaire and Fagerström Test for Nicotine Dependence (FTND) are widely used to study dependence among smokeless tobacco (ST) users. However, there is a need for a dependence measure which is based on the clinical definition of dependence and is easy to administer. The Tobacco Dependence Screener (TDS), a self-administered 10-item scale, is based on the Diagnostic and Statistical Manual, fourth edition (DSM-IV) and ICD-10 definitions of dependence. It is commonly used as a tobacco dependence screening tool in cigarette smoking studies but it has not been evaluated for dependence in ST users. The purpose of this study is to evaluate the TDS as a measure of tobacco dependence among ST users. Data collected from a community-based sample of exclusive ST users living in Oklahoma (n = 95) was used for this study. TDS was adapted to be used for ST dependence as the references for smoking were changed to ST use. Concurrent validity and reliability of TDS were evaluated. Salivary cotinine concentration was used as a criterion variable. Overall accuracy of the TDS was assessed by receiver's operating characteristic (ROC) curve and optimal cutoff scores for dependence diagnosis were evaluated. There was no floor or ceiling effect in TDS score (mean = 5.42, SD = 2.61). Concurrent validity of TDS as evaluated by comparing it with FTND-ST was affirmative. Study findings showed significant association between TDS and salivary cotinine concentration. The internal consistency assessed by Cronbach's alpha indicated that TDS had acceptable reliability (α = 0.765). TDS was negatively correlated with time to first chew/dip and positively correlated with frequency (number of chews per day) and years of ST use. Results of logistic regression analysis showed that at an optimal cutoff score of TDS 5+, ST users classified as dependent had significantly higher cotinine concentration and FTND-ST scores. TDS demonstrated acceptable reliability and

2014-01-01

In ion beam cancer therapy, range verification in patients using positron emission tomography (PET) requires the comparison of measured with simulated positron emitter yields. We found that (1) changes in modeling nuclear interactions strongly affected the positron emitter yields and that (2) Monte...... Carlo simulations with SHIELD-HIT10A reasonably matched the most abundant PET isotopes 11C and 15O. We observed an ion-energy (i.e., depth) dependence of the agreement between SHIELD-HIT10A and measurement. Improved modeling requires more accurate measurements of cross-section values....

This study evaluated the extent to which the addition of disulfiram and contingency management for adherence and abstinence (CM), alone and in combination, might enhance the effects of cognitive behavioral therapy (CBT) for cocaine use disorders. Factorial randomized double blind (for medication condition) clinical trial where CBT served as the platform and was delivered in weekly individual sessions in a community-based outpatient clinic. 99 outpatients who met DSM-IV criteria for current cocaine dependence were assigned to receive either disulfiram or placebo, and either CM or no CM. Cocaine and other substance use was assessed via a daily calendar with thrice weekly urine sample testing for 12 weeks with a one-year follow-up (80% interviewed at one year). The primary hypothesis that CM and disulfiram would produce the best cocaine outcomes was not confirmed, nor was there a main effect for disulfiram. For the primary outcome (percent days of abstinence, self report), there was a significant interaction, with the best cocaine outcomes were seen for the combination of CM and placebo, with the two groups assigned to disulfiram associated with intermediate outcomes, and poorest cocaine outcome among those assigned to placebo and no CM. The secondary outcome (urinalysis) indicated a significant effect favoring CM over no CM but the interaction effect was not significant. One year follow-up data indicated sustained treatment effects across conditions. CM enhances outcomes for CBT treatment of cocaine dependence, but disulfiram provided no added benefit to the combination of CM and CBT. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Gene Therapy with Helper-Dependent Adenoviral Vectors: Current Advances and Future Perspectives

2010-09-01

Full Text Available Recombinant Adenoviral vectors represent one of the best gene transfer platforms due to their ability to efficiently transduce a wide range of quiescent and proliferating cell types from various tissues and species. The activation of an adaptive immune response against the transduced cells is one of the major drawbacks of first generation Adenovirus vectors and has been overcome by the latest generation of recombinant Adenovirus, the Helper-Dependent Adenoviral (HDAd vectors. HDAds have innovative features including the complete absence of viral coding sequences and the ability to mediate high level transgene expression with negligible chronic toxicity. This review summarizes the many aspects of HDAd biology and structure with a major focus on in vivo gene therapy application and with an emphasis on the unsolved issues that these vectors still presents toward clinical application.

Purpose: A persistent challenge for the quality assessment of radiation therapy treatments (e.g. contouring accuracy) is the absence of the known, ground truth for patient data. Moreover, assessment results are often patient-dependent. Computer simulation studies utilizing numerical phantoms can be performed for quality assessment with a known ground truth. However, previously reported numerical phantoms do not include the statistical properties of inter-patient variations, as their models are based on only one patient. In addition, these models do not incorporate tumor data. In this study, a methodology was developed for generating numerical phantoms which encapsulate the statistical variations of patients within radiation therapy, including tumors. Methods: Based on previous work in contouring assessment, geometric attribute distribution (GAD) models were employed to model both the deterministic and stochastic properties of individual organs via principle component analysis. Using pre-existing radiation therapy contour data, the GAD models are trained to model the shape and centroid distributions of each organ. Then, organs with different shapes and positions can be generated by assigning statistically sound weights to the GAD model parameters. Organ contour data from 20 retrospective prostate patient cases were manually extracted and utilized to train the GAD models. As a demonstration, computer-simulated CT images of generated numerical phantoms were calculated and assessed subjectively and objectively for realism. Results: A cohort of numerical phantoms of the male human pelvis was generated. CT images were deemed realistic both subjectively and objectively in terms of image noise power spectrum. Conclusion: A methodology has been developed to generate realistic numerical anthropomorphic phantoms using pre-existing radiation therapy data. The GAD models guarantee that generated organs span the statistical distribution of observed radiation therapy patients

Music therapy (MT) interventions are aimed at creating and developing a relationship between patient and therapist. However, there is a lack of validated observational instruments to consistently evaluate the MT process. The purpose of this study was the validation of Music Therapy Session Assessment Scale (MT-SAS), designed to assess the relationship between therapist and patient during active MT sessions. Videotapes of a single 30-min session per patient were considered. A pilot study on the videotapes of 10 patients was carried out to help refine the items, define the scoring system and improve inter-rater reliability among the five raters. Then, a validation study on 100 patients with different clinical conditions was carried out. The Italian MT-SAS was used throughout the process, although we also provide an English translation. The final scale consisted of 7 binary items accounting for eye contact, countenance, and nonverbal and sound-music communication. In the pilot study, raters were found to share an acceptable level of agreement in their assessments. Explorative factorial analysis disclosed a single homogeneous factor including 6 items (thus supporting an ordinal total score), with only the item about eye contact being unrelated to the others. Moreover, the existence of 2 different archetypal profiles of attuned and disattuned behaviours was highlighted through multiple correspondence analysis. As suggested by the consistent results of 2 different analyses, MT-SAS is a reliable tool that globally evaluates sonorous-musical and nonverbal behaviours related to emotional attunement and empathetic relationship between patient and therapist during active MT sessions.

Efficacy of multiple anticancer therapies may depend on host immune response

Directory of Open Access Journals (Sweden)

Kritika Karri

2017-06-01

Full Text Available The host immune system is a key player in anticancer therapy response and resistance. Although the impact of host immune response in the ‘war against cancer’ has been studied and it has been the basis for immunotherapy, understanding of its role in attenuating the action of conventional anticancer therapies is an area that has not been fully explored. In spite of advances in systemic therapy, the 5-year survival rate for adenocarcinoma is still a mere 13% and the primary reason for treatment failure is believed to be due to acquired resistance to therapy. Hence, there is a need for identifying reliable biomarkers for guided treatment of lung and colon adenocarcinoma and to better predict the outcomes of specific anticancer therapies. In this work, gene expression data were analyzed using public resources and this study shows how host immune competence underscores the efficacy of various anticancer therapies. Additionally, the result provides insight on the regulation of certain biochemical pathways relating to the immune system, and suggests that smart chemotherapeutic intervention strategies could be based on a patient’s immune profile.

Ethnic and cultural differences in patterns of alcohol use disorders must be understood in order to address improvement in prevention of such disorders and accessibility to health care services. The purpose of this study was to evaluate factors that influence the utilization of medical and mental health services among alcohol-dependent and non-alcohol-dependent African Americans. A cohort of 454 African Americans was evaluated. Alcohol-dependent participants were recruited from various inpatient treatment facilities in the Washington, DC, metropolitan area and through advertisement and word of mouth. Non-alcohol-dependent participants were recruited by advertisements. Each participant was administered the Semi-Structured Assessment for the Genetics of Alcoholism to assess alcohol dependency and the Family History Assessment module to access family history of alcoholism. Xl Test and analysis of variance were used to analyze the data. Alcohol dependence was more prevalent among men, those with lower income, those with less education, and they utilized mental health counseling as opposed to medical-based therapy. Increased reports of medical conditions such as migraine (p<.001), loss of consciousness (p=.001), and sexually transmitted diseases: (p<.001) were also associated with alcohol dependency. Other factors, including visits to inpatient treatment programs, were directly related to incidence of alcohol dependency regardless of gender status (p<.001). This study suggests an association exists among alcohol dependence, medical conditions, health care, and mental care utilization among African Americans. Future research may benefit from investigating if an association exists between alcohol use disorders and health care utilization for other ethnic groups.

The aim of this study was to maximise the benefits from clinical trials involving technological interventions such as radiation therapy. High compliance to the quality assurance protocols is crucial. We assessed whether the quality of radiation therapy intervention was evaluated in Cochrane systematic reviews. We searched 416 published Cochrane systematic reviews and identified 67 Cochrane systematic reviews that investigated radiation therapy or radiotherapy as an intervention. For each systematic review, either quality assurance or quality control for the intervention was identified by a description of such processes in the published systematic reviews. Of the 67 Cochrane systematic reviews studied, only two mentioned quality assurance or quality control. Our findings revealed that 65 of 67 (97%) Cochrane systematic reviews of radiation therapy interventions failed to consider the quality of the intervention. We suggest that advice about the evaluation of intervention quality be added to author support materials. © 2017 The Royal Australian and New Zealand College of Radiologists.

The study aim was to describe and quantify physical therapy interventions for infants at high risk for developmental disorders. An observation protocol was developed based on knowledge about infant physical therapy and analysis of directly observable physiotherapeutic (PT) actions. The protocol's psychometric quality was assessed. Videos of 42 infant physical therapy sessions at 4 or 6 months of corrected age were analyzed. The observation protocol classified PT actions into 8 mutually exclusive categories. Virtually all PT actions during treatment could be classified. Inter- and intrarater agreements were satisfactory (intraclass correlations, 0.68-1.00). Approximately 40% of treatment time was spent challenging the infant to produce motor behavior by themselves, whereas approximately 30% of time facilitation techniques were applied. Tradition-based sessions could be differentiated from function-oriented ones. It is possible to document PT actions during physical therapy treatment of infants at high risk for cerebral palsy in a systematic, standardized, and reliable way.

To compare therapeutic response to behavioral therapy for insomnia (BT-I) among hypnotic-dependent insomnia (HDI) patients with and without Cluster C personality disorders. Twenty-three adults with HDI (17 females), aged between 33 and 68 (M = 53; SD = 9.9) were included in the study. Participants completed a personality disorder assessment (baseline), as well as sleep diaries, polysomnography (PSG), and an insomnia severity assessment (baseline, posttreatment, and one-year follow-up). Treatment consisted of eight weeks of individual BT-I and gradual hypnotic medication withdrawal. Multilevel mixed-effects linear regression models examined the interaction between study visit and Cluster C personality disorders status on treatment response to BT-I. Obsessive-compulsive personality disorder (OCPD) was the most prevalent of the Cluster C personality disorders with 38% (n = 8) of participants meeting criteria. There were no significant treatment differences by OCPD status across time as measured by sleep diaries and insomnia severity status. However, there were significant treatment differences by OCPD status by one-year follow-up on PSG outcomes, indicating that patients with OCPD status had shorter and more disrupted sleep than patients without OCPD status. Based on self-reported sleep measures, patients with insomnia and features of OCPD responded equivalently to BT-I at one-year follow-up compared to patients without features of OCPD. However, polysomnography outcomes indicated objective sleep deteriorated in these patients, which may suggest greater vulnerability to relapse.

Post-traumatic stress disorder (PTSD) is the one of the most commonly observed psychiatric disorder in veterans. The condition can lead to considerable social, occupational, and interpersonal dysfunction. PTSD occurring after combat injury appears to be strongly correlated with the extent of injury, and develops over several months. Present study was designed for assessing the cognitive behavioral therapy in the quality of life (QOL) of war-related PTSD in veterans compared to control group and compare applied treatments with each other. In the present study, we assessment effects of cognitive behavioral therapy such as problem solving, exposure therapy and their combination on QOL in 120 Iranian PTSD patients veterans after Iran-Iraq war. They were randomly allocated to one of four equal interventional groups: (a) Problem solving therapy (b) exposure therapy (c) combined therapy (exposure therapy plus problem solving) (d) control group. Before and after study intervention, patients were evaluated by short form-36 (SF-36) questionnaire. Post-test and follow-up SF-36 scores were 55.6±4 and 55.1±3.6 in exposure therapy, 50±4.4 and 56.1±3.8 in problem solving, and 48.73±3.8 and 50.9±4.2 in combined therapy. In comparing to control group, all intervention showed significant improvement in QOL in PTSD patients. According to the results of the present study, behavioral therapy can improve QOL in PTSD patients.

Assessing women's sexuality after cancer therapy: checking assumptions with the focus group technique.

Bruner, D W; Boyd, C P

1999-12-01

Cancer and cancer therapies impair sexual health in a multitude of ways. The promotion of sexual health is therefore vital for preserving quality of life and is an integral part of total or holistic cancer management. Nursing, to provide holistic care, requires research that is meaningful to patients as well as the profession to develop educational and interventional studies to promote sexual health and coping. To obtain meaningful research data instruments that are reliable, valid, and pertinent to patients' needs are required. Several sexual functioning instruments were reviewed for this study and found to be lacking in either a conceptual foundation or psychometric validation. Without a defined conceptual framework, authors of the instruments must have made certain assumptions regarding what women undergoing cancer therapy experience and what they perceive as important. To check these assumptions before assessing women's sexuality after cancer therapies in a larger study, a pilot study was designed to compare what women experience and perceive as important regarding their sexuality with what is assessed in several currently available research instruments, using the focus group technique. Based on the focus group findings, current sexual functioning questionnaires may be lacking in pertinent areas of concern for women treated for breast or gynecologic malignancies. Better conceptual foundations may help future questionnaire design. Self-regulation theory may provide an acceptable conceptual framework from which to develop a sexual functioning questionnaire.

Functional Assessment of Cancer Therapy-Esophagus is a health-related quality of life instrument validated in patients with esophageal cancer. It is composed of a general component and an esophageal cancer subscale. Our objective was to determine whether the baseline Functional Assessment of Cancer Therapy-Esophagus and esophageal cancer subscale scores are associated with survival in patients with stage II and III cancer of the gastroesophageal junction or thoracic esophagus. Data from 4 prospective studies in Canadian academic hospitals were combined. These included consecutive patients with stage II and III esophageal cancer who received neoadjuvant therapy followed by surgery or chemoradiation/radiation alone. All patients completed baseline Functional Assessment of Cancer Therapy-Esophagus. Functional Assessment of Cancer Therapy-Esophagus and esophageal cancer subscale scores were dichotomized on the basis of median scores. Cox regression analyses were performed. There were 207 patients treated between 1996 and 2014. Mean age was 61 ± 10.6 years. Approximately 69.6% of patients (n = 144) had adenocarcinoma. All patients had more than 9 months of follow-up. In patients with stage II and III, 93 deaths were observed. When treated as continuous variables, baseline Functional Assessment of Cancer Therapy-Esophagus and esophageal cancer subscale were associated with survival with hazard ratios of 0.89 (95% confidence interval [CI], 0.81-0.96; P = .005) and 0.68 (95% CI, 0.56-0.82; P cancer being considered for therapy, higher baseline Functional Assessment of Cancer Therapy-Esophagus and esophageal cancer subscale were independently associated with longer survival, even after adjusting for age, stage, histology, and therapy received. Further study is needed, but Functional Assessment of Cancer Therapy-Esophagus may be useful as a prognostic tool to inform patient decision-making and patient selection criteria for studies.

2014-12-01

Full Text Available Background The results of numerous studies indicate strong associations of personality with the occurrence, and also with the treatment, of alcohol dependence. However, there is no agreement regarding the role of particular dimensions of temperament and character in the course of, and for the results of, alcohol rehabilitation therapy. The objective of the present research was to investigate the relationships between the dimensions of temperament and character as they are presented by Robert Cloninger and motivation for maintaining abstinence in the case of male alcohol-dependent individuals concluding the therapy. Participants and procedure Eighty-nine male alcohol-dependent individuals, concluding alcohol rehabilitation therapy in an outpatient setting, were studied. The following research tools were applied: the Temperament and Character Inventory (TCI of R. Clo­ninger in the Polish adaptation of E. Hornowska (2003, and the Motivation for Maintaining Abstinence Inventory, the author of which is M. Ziółkowski. Results Two clusters, differing in the aspect of motivation for maintaining abstinence after the conclusion of the treatment, were distinguished: of individuals manifesting weaker motivation (n = 39 and those manifesting stronger motivation (n = 50. The patients with stronger motivation manifested the following major features: a lower level of harm avoidance, a higher level of reward dependence, and a higher level of cooperativeness. Conclusions Personality as it is presented by Cloninger manifests connections with motivation for maintaining abstinence. The research confirms the need for diagnosing addicted patients in the scope of temperament and character traits.

The Satisfaction with Iron Chelation Therapy (SICT) instrument was developed based on a literature review, in-depth patient and clinician interviews, and cognitive debriefing interviews. An, open-label, single arm, multicenter trial evaluating the efficacy and safety of deferasirox in patients diagnosed with transfusion-dependent iron overload, provided an opportunity to assess the psychometric measurement properties of the instrument. Psychometric analyses were performed using data at baseline from 273 patients with a range of transfusion-dependent iron overload conditions who were participating in a multinational study. Responsiveness was further evaluated for all patients who also had subsequent satisfaction domain scores collected at week 4. Baseline SICT domain scores had acceptable floor and ceiling effects and internal consistency reliability (Cronbach's alpha: 0.75-0.85). Item discriminant and item convergent validity were both excellent although one item in each analysis did not meet the specified criterion. Small to moderate correlations were observed between SICT and Short Form 36 Health Survey (SF-36) domain scores. Patients with the highest levels of serum ferritin at baseline (>3100 ng/mL) were the least satisfied about the Perceived Effectiveness of ICT and vice versa. Satisfaction improved in all patients, although there were no clear differences observed between groups of patients defined according to changes in serum ferritin levels from baseline to week 4 (stable, improved, or worsened). The SICT domains are reliable and valid. Further testing using a more specific criterion (such as assessing patient global ratings of change in satisfaction domains that correspond to the SICT domains) could help to establish with greater confidence the responsiveness of the instrument.

To evaluate a potential beneficial effect of systemic streptokinase therapy in acute myocardial infarction, 36 patients treated with streptokinase intravenously were assessed by radionuclide ventriculography and quantitative 201 Tl myocardial imaging (including SPECT) in comparison with 18 conventionally treated patients. Patients after thrombolysis had significantly higher EF, PFR, and PER as well as fewer wall motion abnormalities compared with controls. These differences were also observed in the subset of patients with anterior wall infarction (AMI), but not in patients with inferior wall infarction (IMI). Quantitative 201 Tl imaging demonstrated significantly smaller percent myocardial defects and fewer pathological stress segments in patients with thrombolysis compared with controls. The same differences were also found in both AMI and IMI patients. Our data suggest a favorable effect of intravenous streptokinase on recovery of left ventricular function and myocardial salvage. Radionuclide ventriculography and quantitative 201 Tl myocardial imaging seem to be reliable tools for objective assessment of therapy effects. (orig.)

Little evidence exists about processes in massage therapy practice. Investigating current frameworks is warranted. This qualitative study is a secondary data analysis using grounded theory to understand how massage therapy experts describe massage therapy practice. 31 massage therapy experts were invited to a 2-day symposium to discuss best practices for the profession. Through qualitative analysis, memoing, and discussion, the data were summarized into themes. Three themes were identified around massage therapy practice: 1) client centered, 2) structure for practice, and 3) influencing factors. Each theme is clarified and expanded. Conceptual models were developed for research and clinical practice and a definition for massage therapy practice was identified. Challenges and limitations are discussed. The goal of providing these models is to give massage therapists tools to deliver the best possible care. The models need testing to see if they help advance the profession.

Zhang, Mingming; Davies, T Claire; Zhang, Yanxin; Xie, Shane

2014-01-01

This article provides a comprehensive review of studies that investigated ankle assessment techniques to better understand those that can be used in the real-time monitoring of rehabilitation progress for implementation in conjunction with robot-assisted therapy. Seventy-six publications published between January 1980 and August 2013 were selected based on eight databases. They were divided into two main categories (16 qualitative and 60 quantitative studies): 13 goniometer studies, 18 dynamometer studies, and 29 studies about innovative techniques. A total of 465 subjects participated in the 29 quantitative studies of innovative measurement techniques that may potentially be integrated in a real-time monitoring device, of which 19 studies included less than 10 participants. Results show that qualitative ankle assessment methods are not suitable for real-time monitoring in robot-assisted therapy, though they are reliable for certain patients, while the quantitative methods show great potential. The majority of quantitative techniques are reliable in measuring ankle kinematics and kinetics but are usually available only for use in the sagittal plane. Limited studies determine kinematics and kinetics in all three planes (sagittal, transverse, and frontal) where motions of the ankle joint and the subtalar joint actually occur.

Cancer therapy has been characterized throughout history by ups and downs, not only due to the ineffectiveness of treatments and side effects, but also by hope and the reality of complete remission and cure in many cases. Within the therapeutic arsenal, alongside surgery in the case of solid tumors, are the antitumor drugs and radiation that have been the treatment of choice in some instances. In recent years, immunotherapy has become an important therapeutic alternative, and is now the first choice in many cases. Nanotechnology has recently arrived on the scene, offering nanostructures as new therapeutic alternatives for controlled drug delivery, for combining imaging and treatment, applying hyperthermia, and providing directed target therapy, among others. These therapies can be applied either alone or in combination with other components (antibodies, peptides, folic acid, etc.). In addition, gene therapy is also offering promising new methods for treatment. Here, we present a review of the evolution of cancer treatments, starting with chemotherapy, surgery, radiation and immunotherapy, and moving on to the most promising cutting-edge therapies (gene therapy and nanomedicine). We offer an historical point of view that covers the arrival of these therapies to clinical practice and the market, and the promises and challenges they present.

The Endocannabinoid System and Sex Steroid Hormone-Dependent Cancers

Directory of Open Access Journals (Sweden)

Thangesweran Ayakannu

2013-01-01

Full Text Available The “endocannabinoid system (ECS” comprises the endocannabinoids, the enzymes that regulate their synthesis and degradation, the prototypical cannabinoid receptors (CB1 and CB2, some noncannabinoid receptors, and an, as yet, uncharacterised transport system. Recent evidence suggests that both cannabinoid receptors are present in sex steroid hormone-dependent cancer tissues and potentially play an important role in those malignancies. Sex steroid hormones regulate the endocannabinoid system and the endocannabinoids prevent tumour development through putative protective mechanisms that prevent cell growth and migration, suggesting an important role for endocannabinoids in the regulation of sex hormone-dependent tumours and metastasis. Here, the role of the endocannabinoid system in sex steroid hormone-dependent cancers is described and the potential for novel therapies assessed.

Therapy evaluation and diagnostic accuracy in neuroendocrine tumours: assessment of radiological methods

International Nuclear Information System (INIS)

Elvin, A.

1993-01-01

The diagnostic accuracy of ultrasonically guided biopsy-gun biopsies was assessed in a group of 47 patients with suspected pancreatic carcinoma. A correct diagnosis was obtained in 44 of the 47 patients (94%). Biopsy-gun biopsy of the pancreas is considered a useful, reliable and non-traumatic method for the diagnosis of pancreatic malignancy. Twenty-five patients with known neuroendocrine tumour disease were biopsied with 1.2 mm and 0.9 mm biopsy-gun needles. The influence of treatment-related fibrosis was also evaluated. The overall diagnostic accuracy with the 0.9 mm needle was 69% as compared to 92% with the 1.2 mm needle. In order to assess the diagnostic accuracy rate for radiologists with different experience of biopsy procedures 175 cases of renal biopsy-gun biopsies were evaluated. No statistical significant difference was found between the different operators. The role of duplex Doppler ultrasound in monitoring interferon treatment-related changes in carcinoid metastases was evaluated. It present duplex Doppler ultrasound does not seem to play a role in the evaluation of tumour therapy in carcinoid patients. Therapy response evaluation was performed with MR imaging in a group of 17 patients with neuroendocrine liver metastases. A significant difference was found between patients responding to and patients with failure of treatment in terms of tumour T1, contrast enhancement and signal intensity ratio. This indicates that MR investigation may be used in therapy monitoring of patients with neuroendocrine metastases. The neuroendocrine-differentiated colonic carcinoma cell line (LCC-18) was transplanted to 29 mice to establish a tumour/animal model that would allow the monitoring of changes with MR imaging induced by interferon therapy and to evaluate whether the therapeutic response could be modulated by different interferon dosages. Interferon does not seem to have any prolonged anti-proliferative effect on the LCC-18 tumour cell line when transplanted to

2013-02-01

The impact of changing antiplatelet therapy on thrombin generation potential in patients with ischaemic cerebrovascular disease (CVD) is unclear. We assessed patients within 4 weeks of TIA or ischaemic stroke (baseline), and then 14 days (14d) and >90 days (90d) after altering antiplatelet therapy. Thrombin generation was assessed in platelet poor plasma. Ninety-one patients were recruited. Twenty-four were initially assessed on no antiplatelet therapy, and then after 14d (N = 23) and 90d (N = 8) on aspirin monotherapy; 52 were assessed on aspirin monotherapy, and after 14 and 90 days on aspirin and dipyridamole combination therapy; 21 patients were assessed on aspirin and after 14 days (N = 21) and 90 days (N = 19) on clopidogrel. Peak thrombin generation and endogenous thrombin potential were reduced at 14 and 90 days (p ≤ 0.04) in the overall cohort. We assessed the impact of individual antiplatelet regimens on thrombin generation parameters to investigate the cause of this effect. Lag time and time-to-peak thrombin generation were unchanged at 14 days, but reduced 90 days after commencing aspirin (p ≤ 0.009). Lag time, peak thrombin generation and endogenous thrombin potential were reduced at both 14 and 90 days after adding dipyridamole to aspirin (p ≤ 0.01). Lag time was reduced 14 days after changing from aspirin to clopidogrel (p = 0.045), but this effect was not maintained at 90 days (p = 0.2). This pilot study did not show any consistent effects of commencing aspirin, or of changing from aspirin to clopidogrel on thrombin generation potential during follow-up. The addition of dipyridamole to aspirin led to a persistent reduction in peak and total thrombin generation ex vivo, and illustrates the diverse, potentially beneficial, newly recognised \\'anti-coagulant\\' effects of dipyridamole in ischaemic CVD.

Full Text Available STUDY BACKGROUND Post acne scars are always a challenge to treat, especially the ones which are deep seated. There are many treatment options like laser resurfacing, dermabrasion, microdermabrasion and non-ablative laser resurfacing but with considerable morbidity and interference with the daily activities of the patient in the post-treatment period. Microneedling or dermaroller therapy is one of the new treatment options in the management of acne scars with satisfactory improvement and no significant side effect. The aim of the present study is to perform an objective evaluation the efficacy of microneedling in the treatment of atrophic acne scars. MATERIALS AND METHODS Thirty patients of skin type III-V having atrophic facial acne scars presenting to our dermatology OPD. were received multiple sittings of microneedling (dermaroller treatment with an interval of 6 weeks between each session. Goodman & Baron’s acne scar grading system was used for assessment of their scars and was evaluated clinically by serial photography at the start as well as at two months after the conclusion of the treatment. Patients on anticoagulant therapy, of keloidal tendency, with bleeding disorders, vitiligo patients, pregnant and lactating mothers and patients with active acne lesions were excluded from the study. The duration of this study was for ten months-from January 2014 to October 2014. RESULTS Any change in the grading of scars after the end of treatment and follow-up period was noted down. The efficacy and improvement of dermaroller treatment was assessed by Goodman and Baron’s Global Acne Scarring System. Out of 30 patients, 26(80.64% patients achieved a reduction in the severity of their scarring by one or two grades. Quantitative assessment showed that 13.3% of patients had minimal, 16.6% had good and 70% showed very good improvement. Adverse effects were limited to transient pain, erythema and edema. CONCLUSION Microneedling therapy seems to be

This study aimed to assess a novel method of three-dimensional (3D) co-registration of prostate magnetic resonance imaging (MRI) examinations performed before and after prostate cancer focal therapy. We developed a software platform for automatic 3D deformable co-registration of prostate MRI at different time points and applied this method to 10 patients who underwent focal ablative therapy. MRI examinations were performed preoperatively, as well as 1 week and 6 months post treatment. Rigid registration served as reference for assessing co-registration accuracy and precision. Segmentation of preoperative and postoperative prostate revealed a significant postoperative volume decrease of the gland that averaged 6.49 cc (P = .017). Applying deformable transformation based on mutual information from 120 pairs of MRI slices, we refined by 2.9 mm (max. 6.25 mm) the alignment of the ablation zone, segmented from contrast-enhanced images on the 1-week postoperative examination, to the 6-month postoperative T2-weighted images. This represented a 500% improvement over the rigid approach (P = .001), corrected by volume. The dissimilarity by Dice index of the mapped ablation zone using deformable transformation vs rigid control was significantly (P = .04) higher at the ablation site than in the whole gland. Our findings illustrate our method's ability to correct for deformation at the ablation site. The preliminary analysis suggests that deformable transformation computed from mutual information of preoperative and follow-up MRI is accurate in co-registration of MRI examinations performed before and after focal therapy. The ability to localize the previously ablated tissue in 3D space may improve targeting for image-guided follow-up biopsy within focal therapy protocols.

Duncan, W.; Arnott, S.J.

1982-01-01

Clinical studies of fast neutron therapy were started in Edinburgh in March 1977. The treatment facility has an isocentric machine and a fixed horizontal beam. The neutron beam is produced by 15 MeV deuterons on a thick beryllium target. Six hundred and forty-one patients have been included in these studies in the four-year period to March 1981. Randomly controlled trials have been conducted since May 1977 and 376 patients have been recruited in this period. The local tumor response rates and morbidity observed is given for trials of patients with cerebral gliomass, squamous carcinoma of the head and neck region, transitional cell carcinoma of the bladder and adenocarcinoma of the rectum. This interim evaluation does not demonstrate any advantage of fast neutron radiotherapy as compared with photon therapy. However, greater numbers of patients require to be studied and followed-up for longer intervals. A definitive assessment of the randomly controlled clinical trials in Edinburgh should be possible at the end of 1982

Many alcohol-dependent patients suffer from cognitive impairment of variable severity, manifested by alterations in retrograde and anterograde memory, visuospatial processing, cognitive abilities and attention, some of which are reversible. In this context, cognitive remediation therapies could significantly improve patients' performance; therefore, these are considered a valuable alternative. The aim of this study was to implement cognitive remediation therapy in patients with alcohol dependence and cognitive impairment and evaluate its viability and effectiveness. The participants were sixteen abstinent, alcohol-dependent patients (mean age of 59 years, 63% males) from the Addictive Behaviours Unit of a tertiary hospital. Over 6 months, a nurse led 1-hour weekly sessions (24 sessions in total) during which exercises for improving functional, social and cognitive performance were completed. Patients were assessed at baseline, at the end of the study and 6 months later, using the Mini-Mental State Examination (MMSE) and the Memory Alteration Test (M@T). Their respective scores were 26.4 (SD 3.16), 29 (SD 1.67) and 27 (SD 3.1) for the MMSE and 38.7 (SD 6.81), 45.7 (SD 5.6) and 41.1 (SD 7.86) for the M@T. Changes were assessed with both Friedman and Wilcoxon signed-rank tests, with mostly statistically significant differences (p < 0.05). Assistance and satisfaction were high. Therefore, the therapy was viable, widely accepted and effective.

The purpose of this study was to evaluate the efficacy and safety of a novel theranostic agent, 177 Lu-DKFZ-PSMA-617 therapy in metastatic castration resistant prostate cancer (mCRPC). Thirty-one mCRPC patients with progressive disease despite second-line hormonal therapy and/or docetaxel chemotherapy were recruited for the study. All patients underwent diagnostic 68 Ga-PSMA-HBED-CCPET/CT, prior to inclusion for therapy. Included patients then underwent quarterly 177 Lu-DKFZ-PSMA-617 therapy. Hematological, kidney function, liver function tests, and serum PSA levels were recorded before and after therapy at 2 weeks, 4 weeks, and 3 month intervals. Biochemical response was assessed with trend in serum PSA levels. Metabolic response was assessed by PERCIST 1 criteria. Clinical response was assessed by visual analogue score (VASmax) analgesic score (AS), Karanofsky performance status (KPS), and toxicity and response criteria of the Eastern Cooperative Oncology Group (ECOG) criteria. The mean age of patients was 65.93 ± 9.77 years (range: 38-81 years). The mean activity administered in the 31 patients was 5069 ± 1845 MBq ranging from one to four cycles. There was a decline in the mean serum PSA levels from the baseline (baseline: 275 ng/mL, post 1st cycle therapy: 141.75 ng/mL). Based on biochemical response criteria 2/31, 20/31, 3/31, and 6/31 had complete response (CR), partial response(PR), stable disease (SD), and progressive disease (PD), respectively. Metabolic response revealed 2/6 patients with CR, and the remaining 3/6 patients with PR and 1/6 patients with SD. The mean VASmax score decreased from 7.5 to 3. The mean analgesic score decreased from 2.5 to 1.8 after therapy. The mean KPS score improved from 50.32 to 65.42 after therapies. The mean ECOG performance status improved from 2.54 to 1.78 after therapy. Two patients experienced grade I and grade II hemoglobin toxicity each. None of the patients experienced nephrotoxicity or hepatotoxicity. 177 Lu

2017-11-28

Cognitive behavioral therapy (CBT) in its basic principle has developed itself as a stand-alone, substantial method of therapy. With effective application in therapy for a range of mental health issues, the spread of CBT methods to Web-based therapy sources is evident. The development of mobile phone apps using CBT principles is increasing within the research area. Despite the move to Web-based methods of therapy, it is argued that these methods lack the same efficacy of face-to-face therapy sessions. The aim of this review was to assess extent research findings with regard to the effectiveness of CBT-related mobile health (mHealth) apps. By assessing only studies employing a randomized controlled trial design, the review aimed to determine app efficacy within the highly regarded method of investigation. A comprehensive literature search was conducted across several databases. Search results were filtered, and results were subject to strict inclusion and exclusion criteria because of the nature of the review. Where possible, analysis of effect size was calculated and results reported. A total of 8 studies investigating the effectiveness of mHealth CBT-related apps across a range of mental health issues were reviewed. Three studies used the app against a control group, and 5 studies used the app intervention against another form of treatment or intervention. A range of effect sizes were seen across all included studies (d=-0.13 to 1.83; 0.03-1.44), with the largest effects often being seen when comparing the data from pre- to posttest for the app engaged group. The studies reviewed support the use of mHealth apps containing CBT principles for a range of mental health issues. However, the effectiveness over longer time periods should be assessed. Researchers and professionals should seek to collaborate effectively when creating new apps to enhance their effectiveness as a treatment for the general public. ©Amy Leigh Rathbone, Laura Clarry, Julie Prescott

Patients with neuroendocrine tumors expressing somatostatin receptors are often treated with 177 Lu[Lu]-octreotate. Despite being highly effective in animal models, 177 Lu[Lu]-octreotate-based therapies in the clinical setting can be optimized further. The aims of the study were to identify and elucidate possible optimization venues for 177 Lu[Lu]-octreotate tumor therapy by characterizing transcriptional responses in the GOT1 small intestine neuroendocrine tumor model in nude mice. GOT1-bearing female BALB/c nude mice were intravenously injected with 15 MBq 177 Lu[Lu]-octreotate (non-curative amount) or mock-treated with saline solution. Animals were killed 1, 3, 7 or 41 d after injection. Total RNA was extracted from the tumor samples and profiled using Illumina microarray expression analysis. Differentially expressed genes were identified (treated vs. control) and pathway analysis was performed. Distribution of differentially expressed transcripts indicated a time-dependent treatment response in GOT1 tumors after 177 Lu[Lu]-octreotate administration. Regulation of CDKN1A, BCAT1 and PAM at 1 d after injection was compatible with growth arrest as the initial response to treatment. Upregulation of APOE and BAX at 3 d, and ADORA2A, BNIP3, BNIP3L and HSPB1 at 41 d after injection suggests first activation and then inhibition of the intrinsic apoptotic pathway during tumor regression and regrowth, respectively. Transcriptional analysis showed radiation-induced apoptosis as an early response after 177 Lu[Lu]-octreotate administration, followed by pro-survival transcriptional changes in the tumor during the regrowth phase. Time-dependent changes in cell cycle and apoptosis-related processes suggest different time points after radionuclide therapy when tumor cells may be more susceptible to additional treatment, highlighting the importance of timing when administering multiple therapeutic agents.

Antsev, A. V.; Pasko, N. I.; Antseva, N. V.

2018-03-01

This paper addresses wear dependence of the generic efficient life period of cutting tools taken as an aggregate of the law of tool wear rate distribution and dependence of parameters of this law's on the cutting mode, factoring in the random factor as exemplified by the complex model of wear. The complex model of wear takes into account the variance of cutting properties within one batch of tools, variance in machinability within one batch of workpieces, and the stochastic nature of the wear process itself. A technique of assessment of wear dependence parameters in a complex model of cutting tool wear is provided. The technique is supported by a numerical example.

Adolescent e-cigarette use (i.e., "vaping") likely confers risk for developing nicotine dependence. However, there have been no studies assessing e-cigarette nicotine dependence in youth. We evaluated the psychometric properties of the 4-item Patient-Reported Outcomes Measurement Information System Nicotine Dependence Item Bank for E-cigarettes (PROMIS-E) for assessing youth e-cigarette nicotine dependence and examined risk factors for experiencing stronger dependence symptoms. In 2017, 520 adolescent past-month e-cigarette users completed the PROMIS-E during a school-based survey (50.5% female, 84.8% White, 16.22[1.19] years old). Adolescents also reported on sex, grade, race, age at e-cigarette use onset, vaping frequency, nicotine e-liquid use, and past-month cigarette smoking. Analyses included conducting confirmatory factor analysis and examining the internal consistency of the PROMIS-E. Bivariate correlations and independent-samples t-tests were used to examine unadjusted relationships between e-cigarette nicotine dependence and the proposed risk factors. Regression models were run in which all potential risk factors were entered as simultaneous predictors of PROMIS-E scores. The single-factor structure of the PROMIS-E was confirmed and evidenced good internal consistency. Across models, larger PROMIS-E scores were associated with being in a higher grade, initiating e-cigarette use at an earlier age, vaping more frequently, using nicotine e-liquid (and higher nicotine concentrations), and smoking cigarettes. Adolescent e-cigarette users reported experiencing nicotine dependence, which was assessed using the psychometrically sound PROMIS-E. Experiencing stronger nicotine dependence symptoms was associated with characteristics that previously have been shown to confer risk for frequent vaping and tobacco cigarette dependence.

2015-01-01

The operating period of nuclear power plants can be prolonged if it can be shown that their safety has remained on a high level, and for this, it is necessary to estimate how the aged systems, structures and components (SSCs) influence the NPP reliability and safety. To emphasize the ageing aspects the case study presented in this paper will assess different time depending models for rate of occurrence of failures with the goal to obtain the best fitting model. A sensitivity analysis for the impact of burn-in failures was performed to improve the result of the goodness of fit test. Based on the analysis results, a conclusion about the existence or the absence of an ageing trend could be developed. A sensitivity analysis regarding of the reliability parameters was performed, and the results were used to observe the impact over the time-dependent rate of occurrence of failures. (authors)

There is clinical evidence that second malignancies in radiation therapy occur mainly within the beam path, i.e. in the medium or high-dose region. The purpose of this study was to assess the risk for developing a radiation-induced tumor within the treated volume and to compare this risk for proton therapy and intensity-modulated photon therapy (IMRT). Instead of using data for specific patients we have created a representative scenario. Fully contoured age- and gender-specific whole body phantoms (4 year and 14 year old) were uploaded into a treatment planning system and tumor volumes were contoured based on patients treated for optic glioma and vertebral body Ewing's sarcoma. Treatment plans for IMRT and proton therapy treatments were generated. Lifetime attributable risks (LARs) for developing a second malignancy were calculated using a risk model considering cell kill, mutation, repopulation, as well as inhomogeneous organ doses. For standard fractionation schemes, the LAR for developing a second malignancy from radiation therapy alone was found to be up to 2.7% for a 4 year old optic glioma patient treated with IMRT considering a soft-tissue carcinoma risk model only. Sarcoma risks were found to be below 1% in all cases. For a 14 year old, risks were found to be about a factor of 2 lower. For Ewing's sarcoma cases the risks based on a sarcoma model were typically higher than the carcinoma risks, i.e. LAR up to 1.3% for soft-tissue sarcoma. In all cases, the risk from proton therapy turned out to be lower by at least a factor of 2 and up to a factor of 10. This is mainly due to lower total energy deposited in the patient when using proton beams. However, the comparison of a three-field and four-field proton plan also shows that the distribution of the dose, i.e. the particular treatment plan, plays a role. When using different fractionation schemes, the estimated risks roughly scale with the total dose difference in%. In conclusion, proton therapy can

To investigate the impact of waiting for psychological therapy on client well-being as measured by the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) global distress (GD) score. Global distress scores were retrieved for all clients referred for psychological therapy in a secondary care mental health service between November 2006 and May 2013 and who had completed a CORE-OM at assessment and first session. GD scores for a subgroup of 103 clients who had completed a CORE-OM during the last therapy session were also reviewed. The study sample experienced a median wait of 41.14 weeks between assessment and first session. The relationship between wait time from referral acceptance to assessment, and assessment GD score was not significant. During the period between assessment and first session no significant difference in GD score was observed. Nevertheless 29.1% of the sample experienced reliable change; 16.0% of clients reliably improved and 13.1% reliably deteriorated whilst waiting for therapy. Demographic factors were not found to have a significant effect on the change in GD score between assessment and first session. Waiting time was associated with post-therapy outcomes but not to a degree which was meaningful. The majority of individuals (54.4%), regardless of whether they improved or deteriorated whilst waiting for therapy, showed reliable improvement at end of therapy as measured by the CORE-OM. The majority of GD scores remained stable while waiting for therapy; however, 29.1% of secondary care clients experienced either reliable improvement or deterioration. Irrespective of whether they improved, deteriorated or remained unchanged whilst waiting for therapy, most individuals who had a complete end of therapy assessment showed reliable improvements following therapy. There was no significant difference in GD score between assessment and first session recordings. A proportion of clients (29.1%) showed reliable change, either improvement or

Objective assessment of image quality VI: imaging in radiation therapy

Barrett, Harrison H; Kupinski, Matthew A; Müeller, Stefan; Halpern, Howard J; Morris, John C III; Dwyer, Roisin

2013-01-01

Earlier work on objective assessment of image quality (OAIQ) focused largely on estimation or classification tasks in which the desired outcome of imaging is accurate diagnosis. This paper develops a general framework for assessing imaging quality on the basis of therapeutic outcomes rather than diagnostic performance. By analogy to receiver operating characteristic (ROC) curves and their variants as used in diagnostic OAIQ, the method proposed here utilizes the therapy operating characteristic or TOC curves, which are plots of the probability of tumor control versus the probability of normal-tissue complications as the overall dose level of a radiotherapy treatment is varied. The proposed figure of merit is the area under the TOC curve, denoted AUTOC. This paper reviews an earlier exposition of the theory of TOC and AUTOC, which was specific to the assessment of image-segmentation algorithms, and extends it to other applications of imaging in external-beam radiation treatment as well as in treatment with internal radioactive sources. For each application, a methodology for computing the TOC is presented. A key difference between ROC and TOC is that the latter can be defined for a single patient rather than a population of patients. (paper)

The development of addiction is marked by a pathological associative learning process that imbues incentive salience to stimuli associated with drug use. Recent efforts to treat addiction have targeted this learning process using cue exposure therapy augmented with d-cycloserine (DCS), a glutamatergic agent hypothesized to enhance extinction learning. To better understand the impact of DCS-facilitated extinction on neural reactivity to drug cues, the present study reports fMRI findings from a randomized, double-blind, placebo-controlled trial of DCS-facilitated cue exposure for cocaine dependence. Twenty-five participants completed two MRI sessions (before and after intervention), with a cocaine-cue reactivity fMRI task. The intervention consisted of 50mg of DCS or placebo, combined with two sessions of cocaine cue exposure and skills training. Participants demonstrated cocaine cue activation in a variety of brain regions at baseline. From the pre- to post-study scan, participants experienced decreased activation to cues in a number of regions (e.g., accumbens, caudate, frontal poles). Unexpectedly, placebo participants experienced decreases in activation to cues in the left angular and middle temporal gyri and the lateral occipital cortex, while DCS participants did not. Three trials of DCS-facilitated cue exposure therapy for cocaine dependence have found that DCS either increases or does not significantly impact response to cocaine cues. The present study adds to this literature by demonstrating that DCS may prevent extinction to cocaine cues in temporal and occipital brain regions. Although consistent with past research, results from the present study should be considered preliminary until replicated in larger samples. Copyright © 2013 Elsevier Ireland Ltd.

Hematological, kidney function, liver function tests, and serum PSA levels were recorded before and after therapy at 2 weeks, 4 weeks, and 3 month intervals. Biochemical response was assessed with trend in serum PSA levels. Metabolic response was assessed by PERCIST 1 criteria. Clinical response was assessed by visual analogue score (VASmax) analgesic score (AS), Karanofsky performance status (KPS), and toxicity and response criteria of the Eastern Cooperative Oncology Group (ECOG) criteria. The mean age of patients was 65.93 ± 9.77 years (range: 38-81 years). The mean activity administered in the 31 patients was 5069 ± 1845 MBq ranging from one to four cycles. There was a decline in the mean serum PSA levels from the baseline (baseline: 275 ng/mL, post 1st cycle therapy: 141.75 ng/mL). Based on biochemical response criteria 2/31, 20/31, 3/31, and 6/31 had complete response (CR), partial response(PR), stable disease (SD), and progressive disease (PD), respectively. Metabolic response revealed 2/6 patients with CR, and the remaining 3/6 patients with PR and 1/6 patients with SD. The mean VASmax score decreased from 7.5 to 3. The mean analgesic score decreased from 2.5 to 1.8 after therapy. The mean KPS score improved from 50.32 to 65.42 after therapies. The mean ECOG performance status improved from 2.54 to 1.78 after therapy. Two patients experienced grade I and grade II hemoglobin toxicity each.

People suffering from substance dependence suffer from various sexual dysfunctions and are at risk for indulging in various high-risk sexual behaviors and thus are vulnerable to acquire various infections such as HIV/AIDS and other sexually transmitted infections. The aim of the study was to evaluate the correlation between sexual dysfunction and high-risk sexual behavior in opioid-dependent men receiving buprenorphine and naltrexone maintenance therapy. Semi-structured questionnaire, brief male sexual functioning inventory and HIV-risk taking behavior scale was administered to a sample of 60 sexually active men, receiving buprenorphine (n = 30) and naltrexone (n = 30) maintenance therapy for opioid dependence. The main outcomes are correlation between severity of sexual dysfunction and HIV-risk taking behavior. The study results showed 83% of the men on buprenorphine and 90% on naltrexone reported at least one of the sexual dysfunction symptoms. There was a negative correlation between sexual dysfunction and HIV-risk taking behavior that suggest severe the dysfunction, higher the risk taking behavior. Significant correlation was present with overall sexual dysfunction and HIV-risk taking behavior (P = 0.028 and in naltrexone receiving group premature ejaculation versus HIV-risk taking behavior however, (P = 0.022, P sexual dysfunctions and HIV-risk taking behavior, which has clinical implication.

Kirchman, M M

1979-07-01

In this study, a methodology was developed and tested for assessing the quality of care in occupational therapy between educational and noneducational clinical settings, as measured by process and outcome. An instrument was constructed for an external audit of the hospital record. Standards drafted by the investigator were established as normative by a panel of experts for use in judging the programs. Hospital records of 84 patients with residual hemiparesis or hemiplegia in three noneducational settings and of 100 patients with similar diagnoses in two educational clinical settings from selected Michigan facilities were chosen by proportionate stratified random sampling. The process study showed that occupational therapy was of significantly higher quality in the educational settings. The outcome study did not show significant differences between types of settings. Implications for education and practice are discussed.

The aim of this study was to assess our clinical experience with infliximab, a monoclonal antitumor necrosis factor antibody, following its approval for treatment of refractory Crohn's disease (CD). We followed 100 consecutive patients with CD (53 women and 47 men; mean age, 41 yr) who received a total of 233 infliximab (5 mg/kg) infusions. Adverse events were noted and clinical response assessed every 2 wk for 6 months after each infusion using the Harvey Bradshaw Index (HBI) for active disease, the Perianal Disease Activity Index (PDAI) for fistulous disease, and steroid withdrawal rates for steroid-sparing efficacy. Indications for therapy were active disease (n = 57), perianal fistulous disease (n = 33), and steroid dependency (n = 10). Significant infusion reactions occurred in 16 patients (6.9% of infusions) including anaphylactic shock in one patient. Fourteen patients experienced infectious adverse events, 13 of whom were on concurrent steroids. Sixty percent of patients with active disease experienced > or = 50% HBI reduction at 2 wk; mean duration of response, 8.2 wk. Three of 26 first-time nonresponders with active disease (12%) responded to a second infusion. Sixty-nine percent of patients with fistulous disease experienced >50% reduction in their PDAI at 2 wk; mean duration of response, 10.9 wk. Four of 10 steroid-dependent patients (40%) discontinued steroid therapy, one of whom recommenced steroid therapy at 24 wk. Our clinical response rates mirror the efficacy reported in the controlled trials for active and fistulous disease. Steroid-sparing efficacy was seen in 40% of steroid-dependent patients. Concurrent steroids did not reduce the risk of significant infusion reactions (6.9%), but did increase the risk of infections.

USING COPULAS TO MODEL DEPENDENCE IN SIMULATION RISK ASSESSMENT

Energy Technology Data Exchange (ETDEWEB)

Dana L. Kelly

2007-11-01

Typical engineering systems in applications with high failure consequences such as nuclear reactor plants often employ redundancy and diversity of equipment in an effort to lower the probability of failure and therefore risk. However, it has long been recognized that dependencies exist in these redundant and diverse systems. Some dependencies, such as common sources of electrical power, are typically captured in the logic structure of the risk model. Others, usually referred to as intercomponent dependencies, are treated implicitly by introducing one or more statistical parameters into the model. Such common-cause failure models have limitations in a simulation environment. In addition, substantial subjectivity is associated with parameter estimation for these models. This paper describes an approach in which system performance is simulated by drawing samples from the joint distributions of dependent variables. The approach relies on the notion of a copula distribution, a notion which has been employed by the actuarial community for ten years or more, but which has seen only limited application in technological risk assessment. The paper also illustrates how equipment failure data can be used in a Bayesian framework to estimate the parameter values in the copula model. This approach avoids much of the subjectivity required to estimate parameters in traditional common-cause failure models. Simulation examples are presented for failures in time. The open-source software package R is used to perform the simulations. The open-source software package WinBUGS is used to perform the Bayesian inference via Markov chain Monte Carlo sampling.

Current techniques to assess chimerism after hematopoietic stem cell transplantation (HSCT) are limited in both sensitivity and precision. These drawbacks are problematic in the context of cellular therapies that frequently result in microchimerism (donor chimerism VSTs). The levels of detection and quantification of the assay were .008% and .023%, with high levels of precision with samples of DNA content ranging from 1 to 300 ng DNA. From the panel of 29 insertion-deletion probes multiple informative markers were found for each of 43 HSCT donor-recipient pairs. In the case of third-party cellular therapies in which there were 3 DNA contributors (recipient, HSCT donor, and T-cell donor), a marker to detect the cellular product in a background of recipient and donor cells was available for 11 of 12 cases (92%). Chimerism by ddPCR was able to quantify chimerism in HSCT recipients and comparison against standard STR analysis in 8 HSCT patients demonstrated similar results, with the advantage of fast turnaround time. Persistence of donor microchimerism in patients undergoing microtransplantation for acute myeloid leukemia was detectable for up to 57 days in peripheral blood and bone marrow. The presence of microtransplant product DNA in bone marrow T cells after cell sorting was seen in the 1 patient tested. In patients receiving third-party VSTs for treatment of refractory viral infections, VST donor DNA was detected at low levels in 7 of 9 cases. ddPCR offers advantages over currently available methods for assessment of chimerism in standard HSCT and cellular therapies.

Assessments for high dose radionuclide therapy treatment planning

International Nuclear Information System (INIS)

Fisher, D.R.

2003-01-01

Advances in the biotechnology of cell specific targeting of cancer and the increased number of clinical trials involving treatment of cancer patients with radiolabelled antibodies, peptides, and similar delivery vehicles have led to an increase in the number of high dose radionuclide therapy procedures. Optimised radionuclide therapy for cancer treatment is based on the concept of absorbed dose to the dose limiting normal organ or tissue. The limiting normal tissue is often the red marrow, but it may sometimes be the lungs, liver, intestinal tract, or kidneys. Appropriate treatment planning requires assessment of radiation dose to several internal organs and tissues, and usually involves biodistribution studies in the patient using a tracer amount of radionuclide bound to the targeting agent and imaged at sequential timepoints using a planar gamma camera. Time-activity curves are developed from the imaging data for the major organ tissues of concern, for the whole body and sometimes for selected tumours. Patient specific factors often require that dose estimates be customised for each patient. In the United States, the Food and Drug Administration regulates the experimental use of investigational new drugs and requires 'reasonable calculation of radiation absorbed dose to the whole body and to critical organs' using the methods prescribed by the Medical Internal Radiation Dose (MIRD) Committee of the Society of Nuclear Medicine. Review of high dose studies shows that some are conducted with minimal dosimetry, that the marrow dose is difficult to establish and is subject to large uncertainties. Despite the general availability of software, internal dosimetry methods often seem to be inconsistent from one clinical centre to another. (author)

To evaluate the potential of in vivo dynamic contrast-enhanced micro-computed tomography (DCE micro-CT) for the assessment of antiangiogenic drug therapy response of mice with mammary carcinoma. 20 female mice with implanted MCF7 tumours were split into control group and therapy group treated with a known effective antiangiogenic drug. All mice underwent DCE micro-CT for the 3D analysis of functional parameters (relative blood volume [rBV], vascular permeability [K], area under the time-enhancement curve [AUC]) and morphology. All parameters were determined for total, peripheral and central tumour volumes of interest (VOIs). Immunohistochemistry was performed to characterise tumour vascularisation. 3D dose distributions were determined. The mean AUCs were significantly lower in therapy with P values of 0.012, 0.007 and 0.023 for total, peripheral and central tumour VOIs. K and rBV showed significant differences for the peripheral (P{sub per}{sup K} = 0.032, P{sub per}{sup rBV} = 0.029), but not for the total and central tumour VOIs (P{sub total}{sup K} = 0.108, P{sub central}{sup K} = 0.246, P{sub total}{sup rBV} = 0.093, P{sub central}{sup rBV} = 0.136). Mean tumour volume was significantly smaller in therapy (P{sub in} {sub vivo} = 0.001, P{sub ex} {sub vivo} = 0.005). Histology revealed greater vascularisation in the controls and central tumour necrosis. Doses ranged from 150 to 300 mGy. This study indicates the great potential of DCE micro-CT for early in vivo assessment of antiangiogenic drug therapy response. (orig.)

Assessing the effectiveness of massage therapy for bilateral cleft lip reconstruction scars.

McKay, Emilie

2014-06-01

Bilateral cleft lips occur when the bones that form the upper lip fail to fuse at birth. Surgical reconstruction creates scars, which may lead to the following impairments: adhesions, decreased oral range of motion, decreased strength of orbicularis oris muscle, and asymmetry of oral region leading to poor self-esteem. The purpose of this case study is to determine the effectiveness of massage therapy in its ability to improve these impairments. A five-week treatment plan consisting of fascial release, kneading, and intraoral techniques. Subjective information was assessed on two scales: restriction of scar and clients attitudes and acceptance of scar. Objective information was cataloged through photographs, a palpatory chart, and a self-created "Pen Test". Results included increase range of motion and strength, decrease restrictions (palpable and subjective), and increase of symmetry. Client's perceived confidence of scar and its appearance increased. The evidence suggests that massage therapy helped with the impairments associated with scars formed by bilateral cleft lip reconstruction.

Postoperative deep sternal wound infection (DSWI) is a serious complication in cardiac surgery (1-5% of patients) with high mortality and morbidity rates. Vacuum-assisted closure (VAC) therapy has shown promising results in terms of wound healing process, postoperative hospital length of stay and lower in-hospital costs. The aim of our retrospective study is to report the outcome of patients with DSWI treated with VAC therapy and to assess the effect of contributory risk factors. Data of 52 patients who have been treated with VAC therapy in a single institution (study period: September 2003-March 2012) were collected electronically through PAtient Tracking System PATS and statistically analysed using SPSS version 20. Of the 52 patients (35 M: 17 F), 88·5% (n = 46) were solely treated with VAC therapy and 11·5% (n = 6) had additional plastic surgical intervention. Follow-up was complete (mean 33·8 months) with an overall mortality rate of 26·9% (n = 14) of whom 50% (n = 7) died in hospital. No death was related to VAC complications. Patient outcomes were affected by pre-operative, intra-operative and postoperative risk factors. Logistic EUROscore, postoperative hospital length of stay, advanced age, chronic obstructive pulmonary disease (COPD) and long-term corticosteroid treatment appear to be significant contributing factors in the long-term survival of patients treated with VAC therapy. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

The purpose of this pilot study was to assess whether outcome in metastatic or recurrent breast cancer patients is related to metabolic response to endocrine therapy determined by 18 F-FDG PET/CT. The study group comprised 22 patients with breast cancer (age 58 ± 11 years, mean ± SD) who were scheduled to receive endocrine therapy. They were systematically assessed by PET/CT at baseline and after a mean of 10 ± 4 weeks for evaluation of response after induction. All patients demonstrated FDG-avid lesions on the baseline PET/CT scan. The metabolic response was assessed according to EORTC criteria and based on the mean difference in SUV max between the two PET/CT scans, and the patients were classified into four groups: complete or partial metabolic response, or stable or progressive metabolic disease (CMR, PMR, SMD and PMD, respectively). All patients were followed in our institution. Metastatic sites were localized in bone (n = 15), lymph nodes (n = 11), chest wall (n = 3), breast (n = 5), lung (n = 3), soft tissue (n = 1) and liver (n = 1). PMR was observed in 11 patients (50%), SMD in 5 (23%) and PMD in 6 (27%). The median progression-free survival (PFS) times were 20, 27 and 6 months in the PMR, SMD and PMD groups, respectively. PFS in the SMD group differed from that in the PMR and SMD groups (p < 0.0001). Metabolic response assessed by FDG PET/CT imaging in patients with metastatic breast cancer treated with endocrine therapy is predictive of the patients' PFS. (orig.)

Personality disorders (PDs) have been shown to be modestly heritable. Accurate heritability estimates are, however, dependent on reliable measurement methods, as measurement error deflates heritability. The aim of this study was to estimate the heritability of DSM-IV avoidant and dependent personality disorder, by including two measures of the PDs at two time points. Data were obtained from a population-based cohort of young adult Norwegian twins, of whom 8045 had completed a self-report questionnaire assessing PD traits. 2794 of these twins subsequently underwent a structured diagnostic interview for DSM-IV PDs. Questionnaire items predicting interview results were selected by multiple regression, and measurement models of the PDs were fitted in Mx. The heritabilities of the PD factors were 0.64 for avoidant PD and 0.66 for dependent PD. No evidence of common environment, that is, environmental factors that are shared between twins and make them similar, was found. Genetic and environmental contributions to avoidant and dependent PD seemed to be the same across sexes. The combination of both a questionnaire- and an interview assessment of avoidant and dependent PD results in substantially higher heritabilities than previously found using single-occasion interviews only. © 2012 John Wiley & Sons A/S.

Background: Magnet therapy has been used increasingly as a new method to alleviate pain. Magnetic products are marketed with claims of effectiveness for reducing pain of various origins. However, there are inconsistent results from a limited number of randomized controlled trials (RCTs) testing the analgesic efficacy of magnet therapy. This study aimed to evaluate the safety and effectiveness of magnet therapy on reliving various types of pain. Methods: A systematic search of two main medical databases (Cochrane Library and Ovid Medline) was conducted from 1946 to May 2014. Only English systematic reviews that compared magnet therapy with other conventional treatments in patients with local pain in terms of pain relieving measures were included. The results of the included studies were thematically synthesized. Results: Eight studies were included. Magnet therapy could be used to alleviate pain of various origins including pain in various organs, arthritis, myofascial muscle pain, lower limb muscle cramps, carpal tunnel syndrome and pelvic pain. Results showed that the effectiveness of magnetic therapy was only approved in muscle pains, but its effectiveness in other indications and its application as a complementary treatment have not been established. Conclusion: According to the results, it seems that magnet therapy could not be an effective treatment for relieving different types of pain. Our results highlighted the need for further investigations to be done in order to support any recommendations about this technology.

The present study addressed convergence between self-report and indirect approaches to assessing dependency. We were moderately successful in validating an implicit measure, which was found to be reliable, orthogonal to 2 self-report instruments, and predictive of external criteria. This study also examined discrepancies between scores on self-report and implicit measures, and has implications for their significance. The possibility that discrepancies themselves are pathological was not supported, although discrepancies were associated with particular personality profiles. Finally, this study offered additional evidence for the relation between dependency and depressive symptomatology and identified implicit dependency as contributing unique variance in predicting past major depression.

Constitutive MET signaling promotes invasiveness in most primary and recurrent GBM. However, deployment of available MET-targeting agents is confounded by lack of effective biomarkers for selecting suitable patients for treatment. Because endogenous HGF overexpression often causes autocrine MET activation, and also indicates sensitivity to MET inhibitors, we investigated whether it drives the expression of distinct genes which could serve as a signature indicating vulnerability to MET-targeted therapy in GBM. Interrogation of genomic data from TCGA GBM (Student's t test, GBM patients with high and low HGF expression, p ≤ 0.00001) referenced against patient-derived xenograft (PDX) models (Student's t test, sensitive vs. insensitive models, p ≤ 0.005) was used to identify the HGF-dependent signature. Genomic analysis of GBM xenograft models using both human and mouse gene expression microarrays (Student's t test, treated vs. vehicle tumors, p ≤ 0.01) were performed to elucidate the tumor and microenvironment cross talk. A PDX model with EGFR(amp) was tested for MET activation as a mechanism of erlotinib resistance. We identified a group of 20 genes highly associated with HGF overexpression in GBM and were up- or down-regulated only in tumors sensitive to MET inhibitor. The MET inhibitors regulate tumor (human) and host (mouse) cells within the tumor via distinct molecular processes, but overall impede tumor growth by inhibiting cell cycle progression. EGFR (amp) tumors undergo erlotinib resistance responded to a combination of MET and EGFR inhibitors. Combining TCGA primary tumor datasets (human) and xenograft tumor model datasets (human tumor grown in mice) using therapeutic efficacy as an endpoint may serve as a useful approach to discover and develop molecular signatures as therapeutic biomarkers for targeted therapy. The HGF dependent signature may serve as a candidate predictive signature for patient enrollment in clinical trials using MET inhibitors

Full Text Available This qualitative scientific study – by means of analysing recorded therapeutic sessions with children with autism or mental disability in a special school – examines the process of creating a relationship between the therapist and the child in the context of music-therapeutic moments. The analysis of therapeutic moments was carried out through the AQR-instrument (Assessment of the Quality of Relationship and led to a the evaluation of the quality of relationship between the therapist and the child with autism or mental disability during therapy, b the evaluation of the correspondence of the therapeutic intervention to each child’s developmental level (modus, and c the appreciation of the differentiation in the relationship between the therapist and the child with autism or mental disability, as well as the size of that differentiation. Regardless of the pathology, it was observed that music therapy with children is advisable when the child shows disorders in his/her emotional development and in the ability to create a relationship. Music-therapeutic interventions that use the child itself as a starting point and follow the concept of elemental music, succeed in mobilising children’s healthy part and promote their development, in many areas. Research data are based on the author’s dissertation thesis: “Music therapy for children with psychological disorders in special education” (Fragkouli 2012.

Preclinical assessment of curcumin as a potential therapy for B-CLL.

2007-01-01

Curcumin, the principle component of the spice turmeric, has been used as an anti-inflammatory medication in India and China for centuries. Recent studies, predominantly using actively dividing cell lines, have suggested that this compound could be used as a chemopreventative or therapeutic agent for epithelial tumors. As curcumin has been reported to inhibit the NIK/IKK complex, an activity that would be expected to induce apoptosis in B cell malignancies, we sought to determine whether curcumin induces apoptosis in vitro in primary chronic lymphocytic leukemia (B-CLL) cells. Primary leukemic cells were incubated with varying dosages of curcumin, followed by assessment for apoptosis. The role of PPARgamma or NF-kappaB signaling in curcumin-induced apoptosis was examined by cotreatment with a PPARgamma antagonist or EMSA of nuclear NFkappaB complexes. We also examined whether a clinically achievable concentration of curcumin (1 microM) would augment the apoptotic effects of fludarabine, dexamethasone, vincristine or the PDE4 inhibitor rolipram. In B-CLL cells from 14 patients, curcumin-induced apoptosis with a mean EC(50) of 5.5 microM. In contrast, the EC(50) for whole mononuclear cells from a healthy donor was 21.8 microM. In a 48 hr wash-out time course, curcumin-induced apoptosis was time-dependent, with a substantial reduction in apoptosis observed when curcumin was removed after 5 hr. Curcumin treatment reduced basal nuclear NF-kappaB levels and 1 microM curcumin augmented both vinca alkaloid and PDE4 inhibitor-induced apoptosis in B-CLL cells. Our studies suggest that curcumin may augment the efficacy of established or experimental therapies for B-CLL.

Full Text Available Abstract Background Although the Functional Assessment of Cancer Therapy – General questionnaire (FACT-G has been validated few studies have explored the factor structure of the instrument, in particular using non-sample dependent measurement techniques, such as Rasch Models. Furthermore, few studies have explored the relationship between item fit to the Rasch Model and clinical utility. The aim of this study was to investigate the dimensionality and measurement properties of the FACT-G with Rasch Models and Factor analysis. Methods A factor analysis and Rasch analysis (Partial Credit Model was carried out on the FACT-G completed by a heterogeneous sample of cancer patients (n = 465. For the Rasch analysis item fit (infit mean squares ≥ 1.30, dimensionality and item invariance were assessed. The impact of removing misfitting items on the clinical utility of the subscales and FACT-G total scale was also assessed. Results The factor analysis demonstrated a four factor structure of the FACT-G which broadly corresponded to the four subscales of the instrument. Internal consistency for these four scales was very good (Cronbach's alpha 0.72 – 0.85. The Rasch analysis demonstrated that each of the subscales and the FACT-G total scale had misfitting items (infit means square ≥ 1.30. All these scales with the exception of the Social & Family Well-being Scale (SFWB were unidimensional. When misfitting items were removed, the effect sizes and the clinical utility of the instrument were maintained for the subscales and the total FACT-G scores. Conclusion The results of the traditional factor analysis and Rasch analysis of the FACT-G broadly agreed. Caution should be exercised when utilising the Social & Family Well-being scale and further work is required to determine whether this scale is best represented by two factors. Additionally, removing misfitting items from scales should be performed alongside an assessment of the impact on clinical utility.

Psychological distress might affect the international normalized ratio (INR), but effects might vary depending on oral anticoagulant (OAC) therapy. To investigate the association of psychological distress with INR and clotting factors of the extrinsic pathway in patients with and without OAC therapy. We studied 190 patients with a previous venous thromboembolism (VTE); 148 had discontinued OAC therapy and 42 had ongoing OAC therapy. To assess psychological distress, all patients completed validated questionnaires to measure symptoms of depression, anxiety, worrying, anger and hostility. INR, fibrinogen, factor (F)II:C, FV:C, FVII:C and FX:C were measured as part of outpatient thrombophilia work-up. In VTE patients without OAC therapy, the odds of a reduced INR (therapy, INR was unrelated to a negative affect; however, lower FVII:C related to anxiety and worrying as well as lower FX:C related to anger and hostility were observed in patients with OAC therapy compared with those without OAC therapy. Psychological distress was associated with a reduced INR in VTE patients without OAC therapy. The direction of the association between psychological distress and activity in some clotting factors of the extrinsic coagulation pathway might differ depending on whether VTE patients are under OAC therapy or not. © 2012 International Society on Thrombosis and Haemostasis.

Implementation of condition-dependent probabilistic risk assessment using surveillance data on passive components

Highlights: • Condition-dependent probabilistic risk assessment (PRA). • Time-dependent characterization of plant-specific risk. • Containment bypass involving in secondary system piping and SCC in SG tubes. - Abstract: A great deal of surveillance data are collected for a nuclear power plant that reflect the changing condition of the plant as it ages. Although surveillance data are used to determine failure probabilities of active components for the plant’s probabilistic risk assessment (PRA) and to indicate the need for maintenance activities, they are not used in a structured manner to characterize the evolving risk of the plant. The present study explores the feasibility of using a condition-dependent PRA framework that takes a first principles approach to modeling the progression of degradation mechanisms to characterize evolving risk, periodically adapting the model to account for surveillance results. A case study is described involving a potential containment bypass accident sequence due to the progression of flow-accelerated corrosion in secondary system piping and stress corrosion cracking of steam generator tubes. In this sequence, a steam line break accompanied by failure to close of a main steam isolation valve results in depressurization of the steam generator and induces the rupture of one or more faulted steam generator tubes. The case study indicates that a condition-dependent PRA framework might be capable of providing early identification of degradation mechanisms important to plant risk.

With the development of new ENT techniques, many male transsexuals who wish to become women usually request a surgical procedure to raise the fundamental frequency of the voice (feminization). The ENT specialist and the voice-therapist have to use an interdisciplinary approach to this growing social demand. The aim of this study was to show the results in a group of transsexual patients after Wendler's anterior synechiae, with additional voice-therapy treatment. Ten male transexulas who wish to become women patients who had Wendler glottoplasty and voice-therapy were assessed. The surgical procedure consisted of a de-epithelialization of the anterior third of both vocal folds; this area was sutured and the surface of both vocal folds was vaporised with laser diode. Pre- and postsurgery voice assessment consisted of measuring fundamental frequency (Fo) and maximum phonation time, administering the transgender self-assessment questionnaire (TSEQ) and obtaining perceptual voice assessment by inter-rater agreement. All the male transsexuals who wish to become women patients significantly increased their Fo (106 Hz on average) after the treatment. Furthermore, significant improvements were shown in self-reported satisfaction and in the degree of voice feminization. No improvements in the maximum phonation time were observed. Wendler glottoplasty is a surgical procedure to contribute to feminising the voice, with good medium-term results and without noteworthy medical complications. The increase in vocal tone was observed using several pre- and post-surgery control measures and voice therapy.

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

Opioid misuse is a large public health problem in the United States. Residents of rural areas and American Indian (AI) reservation/trust lands represent traditionally underserved populations with regard to substance-use disorder therapy. Assess differences in the number of opioid agonist therapy (OAT) facilities and physicians with Drug Addiction Treatment Act (DATA) waivers for rural versus urban, and AI reservation/trust land versus non-AI reservation/trust land areas in Washington State. The unit of analysis was the ZIP code. The dependent variables were the number of OAT facilities and DATA-waivered physicians in a region per 10,000 residents aged 18-64 in a ZIP code. A region was defined as a ZIP code and its contiguous ZIP codes. The independent variables were binary measures of whether a ZIP code was classified as rural versus urban, or AI reservation/trust land versus non-AI reservation/trust land. Zero-inflated negative binomial regressions with robust standard errors were estimated. The number of OAT clinics in a region per 10,000 ZIP-code residents was significantly lower in rural versus urban areas (P = .002). This did not differ significantly between AI reservation/trust land and non-AI reservation/trust land areas (P = .79). DATA-waivered physicians in a region per 10,000 ZIP-code residents was not significantly different between rural and urban (P = .08), or AI reservation/trust land versus non-AI reservation/trust land areas (P = .21). It appears that the potential for Washington State residents of rural and AI reservation areas to receive OAT is similar to that of residents outside of those areas; however, difficulties in accessing therapy may remain, highlighting the importance of expanding health care insurance and providing support for DATA-waivered physicians. © 2016 National Rural Health Association.

2015-11-01

Full Text Available Reliable response criteria are critical for the evaluation of therapeutic response in hepatocellular carcinoma (HCC. Current response assessment is mainly based on: (1 changes in size, which is at times unreliable and lag behind the result of therapy; and (2 contrast enhancement, which can be difficult to quantify in the presence of benign post-procedural changes and in tumors presenting with a heterogeneous pattern of enhancement. Given these challenges, functional magnetic resonance imaging (MRI techniques, such as diffusion-weighted imaging (DWI have been recently investigated, aiding specificity to locoregional therapy response assessment and outcome prediction. Briefly, DWI quantifies diffusion of water occurring naturally at a cellular level (Brownian movement, which is restricted in multiple neoplasms because of high cellularity. Disruption of cellular integrity secondary to therapy results in increased water diffusion across the injured membranes. This review will provide an overview of the current literature on DWI therapy response assessment and outcome prediction in HCC following treatment with locoregional therapies.

[The influence of hormonal replacement therapy on bone density in postmenopausal women depending on polymorphism of vitamin D receptor (VDR) and estrogen receptor (ER) genes].

Osteoporosis is still an important health problem in modern societies. The densitometric criterion for the diagnosis of this condition established by WHO in 1994 is bone mass density (BMD) lower than 2.5 standard deviation (SD) from the mean value for young healthy individuals of the same sex. Between 60 and 90% of bone density (quantity of bone tissue in the human skeleton) at the time when growth is terminated is genetically determined. For this reason, genes predisposing to osteoporosis and mechanisms of their activity remain the object of investigations. Among them are genes coding for vitamin D receptor (VDR), estrogen receptor (ER), type I collagen, TGF-beta and IL-6. Diminishing bone density past the age of thirty is a physiologic process. Bone loss averages 0.3-0.6% per year. Acceleration of this process to 1.2-6% per year in postmenopausal women has been attributed to constantly decreasing estrogen concentration. Hence, the gold standard in osteoporosis prevention and treatment includes estrogen-progestagen therapy enriched with vitamin D analogues, calcium-rich diet and regular physical exercises. Treatment of osteoporosis can be long and expensive. The condition may lead to disability. Osteoporotic fractures and their complications may be fatal. For these reasons, the chief priority in osteoporosis is prevention. Unfortunately, current diagnostic methods (for detection of osteoporosis and monitoring of treatment) remain unsatisfactory. Molecular techniques offer a promising approach to diagnosis and monitoring of therapy. Additionally, the risk of osteoporosis in 1st degree relatives can be assessed and early prevention can be started. The present study addressed the following questions: 1. Are there differences in spine BMD in untreated women with postmenopausal osteoporosis depending on polymorphism of VDR and ER genes? 2. Does efficacy of treatment (increase in spine BMD) in women with postmenopausal osteoporosis depend on polymorphism of VDR and ER

This research was based on the hypothesis that when alcohol-dependent patients describe themselves, awakening of emotion by affirmative odor stimulation may facilitate memory reframing focusing on more affirmative emotion and memories. To prove the hypothesis, physiological changes accompanied by emotional awakening were evaluated by measuring the autonomic activity. In addition, subjective evaluation by a self-report manner was examined to investigate the effectiveness of Reminiscence Therapy (RT) using odor in alcohol-dependent patients. Thirty-four patients who met the DSM-IV criteria of alcohol-related disorders and were hospitalized in a ward specialized to alcohol dependence therapy. Each patient underwent a one-to-one interview twice. For counterbalance, one interview was performed with odor stimulation using an odor with a relaxing effect that recall pleasant emotion, and the other was without odor stimulation. As the evaluation indices of physiological changes accompanied by emotional awakening, index of autonomic function (HRV; Heart rate variability) for objective evaluation and psychological indices (STAI; State-Trait Anxiety Inventory VAS; Visual Analog Scale) for subjective evaluation were measured. 1) Objective evaluation: Regarding the evaluation index of the autonomic function, the sympathetic nervous system activity (LF/HF; low frequency component/high frequency component ratio) was significantly inhibited by odor stimulation (p Subjective evaluation: Compared to the state prior to interview, state anxiety judged by STAI was significantly decreased after interview (p subjective evaluation, but the objective evaluation suggested that the odor inhibited the sympathetic nervous system. Thus, it was suggested that odor can be used in RT, that is, emotional changes due to stimulation of odor may be applicable in RT.

Back pain is quite common in contemporary society, whose expectations of an effective analgesic therapy in conservative treatment lead to a necessity of searching for new diagnostic and therapeutic methods in physiotherapy. Out of the numerous physical therapy methods, Multiple Impulse Therapy (MIT) deserves special consideration. This paper aims to present and analyse the outcomes of MIT concerning paraspinal muscle tone and pain intensity in patients with low back pain. The study enrolled 117 patients (50 women and 67 men; average age of 45.3 yrs) with lumbar conditions confirmed by imaging studies. The participants received five MIT sessions within 14 days. Moreover, both before and after the therapy all the patients underwent bilateral assessment of the paraspinal muscle tone by surface electromyography (sEMG) with the NoraxonMyoTrace 400 system and an interactive head of the PulStarFRAS device. A VAS was used for evaluation of pain severity. The analysis of significance of differences between scores before and after treatment showed that all the parameters changed significantly (MIT: 11.11 Ibf before and 8.89 Ibf after the therapy; VAS: 6.04 before and 3.38 afterwards; sEMG: 9.29uV before and 7.51uV afterwards). 1. Multiple Impulse Therapy (MIT) is an effective and non-invasive method of back pain treatment. 2. MIT significantly reduces paraspinal muscle tone, as confirmed by sEMG results, and shows a strong analgesic effect.

Janaína Barden Schallemberger

Full Text Available Abstract Introduction: Benzodiazepines are among the most prescribed drugs for anxiety and one of the most used drug classes in the world and have a high potential for addiction. The objective of this study was to assess levels of dependence and anxiety among users of these drugs in the public health system. Methods: This was a cross-sectional, descriptive and quantitative study. Benzodiazepine users treated on the public health system were selected. Anxiety levels were assessed with the Hamilton Anxiety Scale and dependency with the Benzodiazepine Dependence Self-Report Questionnaire. Results: Benzodiazepine use was higher among women and in older age groups. Duration of benzodiazepine use was greater than 1 year for all respondents. The dependence assessment indicated that more than half of users were dependent on taking benzodiazepines and most had a severe degree of anxiety. Conclusion: This study found evidence of prolonged and inappropriate use of benzodiazepines. It is necessary to educate users about the risks of these drugs and to develop strategies to rationalize use of these drugs by working with prescribers and dispensers.

Assessing the utility of frequency dependent nudging for reducing biases in biogeochemical models

Bias errors, resulting from inaccurate boundary and forcing conditions, incorrect model parameterization, etc. are a common problem in environmental models including biogeochemical ocean models. While it is important to correct bias errors wherever possible, it is unlikely that any environmental model will ever be entirely free of such errors. Hence, methods for bias reduction are necessary. A widely used technique for online bias reduction is nudging, where simulated fields are continuously forced toward observations or a climatology. Nudging is robust and easy to implement, but suppresses high-frequency variability and introduces artificial phase shifts. As a solution to this problem Thompson et al. (2006) introduced frequency dependent nudging where nudging occurs only in prescribed frequency bands, typically centered on the mean and the annual cycle. They showed this method to be effective for eddy resolving ocean circulation models. Here we add a stability term to the previous form of frequency dependent nudging which makes the method more robust for non-linear biological models. Then we assess the utility of frequency dependent nudging for biological models by first applying the method to a simple predator-prey model and then to a 1D ocean biogeochemical model. In both cases we only nudge in two frequency bands centered on the mean and the annual cycle, and then assess how well the variability in higher frequency bands is recovered. We evaluate the effectiveness of frequency dependent nudging in comparison to conventional nudging and find significant improvements with the former.

This article, Part 1 of the Endocrine Society of Australia's position statement on male hypogonadism, focuses on assessment of male hypogonadism, including the indications for testosterone therapy. (Part 2 will deal with treatment and therapeutic considerations.) Key points and recommendations are:Pathological hypogonadism arises due to diseases of the hypothalamus or pituitary gland (hypogonadotropic hypogonadism) or testes (hypergonadotropic hypogonadism). It is a clinical diagnosis with a pathological basis, confirmed by hormone assays.Hormonal assessment is based on measurement of circulating testosterone, luteinising hormone (LH) and follicle-stimulating hormone (FSH) concentrations. Measurement of sex hormone-binding globulin levels can be informative, but use of calculated free testosterone is not recommended for clinical decision making.Testosterone replacement therapy is warranted in men with pathological hypogonadism, regardless of age.Currently, there are limited data from high-quality randomised controlled trials with clinically meaningful outcomes to justify testosterone treatment in older men, usually with chronic disease, who have low circulating testosterone levels but without hypothalamic, pituitary or testicular disease.Obesity, metabolic syndrome and type 2 diabetes are associated with lowering of circulating testosterone level, but without elevation of LH and FSH levels. Whether these are non-specific consequences of non-reproductive disorders or a correctable deficiency state is unknown, but clear evidence for efficacy and safety of testosterone therapy in this setting is lacking.Glucocorticoid and opioid use is associated with possibly reversible reductions in circulating testosterone level, without elevation of LH and FSH levels. Where continuation of glucocorticoid or opioid therapy is necessary, review by an endocrinologist may be warranted.Changes in management as result of the position statement: Men with pathological hypogonadism should

Full Text Available One of the main characteristics of cognitive-behavior therapy is that it is based on a specific clinical formulation of the case. This means that the therapist, using interviews and inventories, in a particular way, needs to understand and integrate the history of his/her client and his/her current problems. Clinical strategies can be then tailored to deal with the client’s difficulties. The establishment of adequate and warm interpersonal and therapeutical relationship depends greatly on this empathic and accurate understanding of the client’s problems. The present article intends to present this approach to case formulation based on a cognitive behavior perspective. It also includes a brief review of theoretic-clinical aspects, assessment tools and suggested procedures. The conclusion is that an adequate  formulation is essential to success in psychotherapy.

Satisfaction with treatment is considered a relevant factor for assessing results in clinical practice. However, when assessing satisfaction in dependent patients, the opinion of their caregivers becomes crucial, since implicit in satisfaction is the degree of caregiver involvement, of adherence to treatment, and lastly of better care of these patients. The purpose of this study was to develop, validate, and administer two versions of a specific questionnaire to assess satisfaction with blood glucose-lowering treatment in caregivers of dependent type 2 diabetic patients. This was an observational, descriptive, epidemiological study conducted in the Los Montalvos Internal Medicine Department at the University Hospital of Salamanca (Spain). Two versions of the questionnaire to assess caregivers' satisfaction with current treatment and after introducing changes in therapy were created and validated according to model procedures. Once validated, the questionnaires were implemented in 219 cases. Cronbach's α-coefficient, correlation between all the items, intraclass correlation coefficient, and correlation between the obtained scores and satisfaction with blood glucose levels all satisfied the standard for validation. Significant levels of correlation were observed between the degree of satisfaction and the number of daily administrations of the blood glucose-lowering medication (Spearman's r=-0.21, Ppatients receiving more frequent administration of their antidiabetic medication prior to the change were more satisfied with the change (r=0.24, Psatisfaction (r=-0.43, Psatisfaction was validated. When applied to our cohort of cases, the obtained data suggest that simplicity in antidiabetic therapy should be considered in the management of dependent type 2 diabetic patients when caregivers' satisfaction is an additional objective.

To overcome the limitation of single pH-dependent delivery systems, in this study, we developed and evaluated the therapeutic potential of budesonide-loaded dual pH/time-dependent nanoparticles (NPs for the treatment of colitis. Eudragit FS30D was used as a pH-dependent polymer, and Eudragit RS100 as a time-dependent controlled release polymer. Single pH-dependent NPs (pH_NPs, single time-dependent NPs (Time_NPs, and dual pH/time-dependent NPs (pH/Time_NPs were prepared using the oil-in-water emulsion method. The physicochemical properties and drug release profiles of these NPs in gastrointestinal (GI tract conditions were investigated. The therapeutic potential and in vivo distribution of the NPs were evaluated in a dextran sulfate sodium (DSS-induced colitis mice model. The pH/Time_NPs prevented a burst drug release in acidic pH conditions and showed sustained release at a colonic pH. The in vivo distribution study in the mice GI tract demonstrated that pH/Time_NPs were more efficiently delivered to the inflamed colon than pH_NPs were. Compared to the single pH_NPs-treated group, the pH/Time_NPs-treated group showed increased body weight and colon length and markedly decreased disease activity index, colon weight/length ratios, histological damage, and inflammatory cell infiltration in colon tissue. Our results demonstrate that the dual pH/time-dependent NPs are an effective oral colon-targeted delivery system for colitis therapy.Keywords: colon-specific delivery, dual-sensitive delivery

Full Text Available Introduction: People suffering from substance dependence suffer from various sexual dysfunctions and are at risk for indulging in various high-risk sexual behaviors and thus are vulnerable to acquire various infections such as HIV/AIDS and other sexually transmitted infections. AIM: The aim of the study was to evaluate the correlation between sexual dysfunction and high-risk sexual behavior in opioid-dependent men receiving buprenorphine and naltrexone maintenance therapy. Materials and Methods: Semi-structured questionnaire, brief male sexual functioning inventory and HIV-risk taking behavior scale was administered to a sample of 60 sexually active men, receiving buprenorphine (n = 30 and naltrexone (n = 30 maintenance therapy for opioid dependence. Results: The main outcomes are correlation between severity of sexual dysfunction and HIV-risk taking behavior. The study results showed 83% of the men on buprenorphine and 90% on naltrexone reported at least one of the sexual dysfunction symptoms. There was a negative correlation between sexual dysfunction and HIV-risk taking behavior that suggest severe the dysfunction, higher the risk taking behavior. Significant correlation was present with overall sexual dysfunction and HIV-risk taking behavior (P = 0.028 and in naltrexone receiving group premature ejaculation versus HIV-risk taking behavior however, (P = 0.022, P < 0.05 there were no significant differences among both the groups except above findings. Conclusion: Conclusion was treatment is associated with sexual dysfunctions and HIV-risk taking behavior, which has clinical implication. Future research should explore this further using biochemical analyses.

Treatment adherence has posed a substantial challenge not only for patients but also for the health profession for many decades. The last 5 years has witnessed significant attention toward adherence with cognitive behavioral therapy (CBT) homework for anxiety and depressive disorders, and adherence assessment methods have diversified. However, there remains a large component of the adherence process not assessed in CBT, with patient effort, engagement, and the known role for treatment appraisals and beliefs necessitating the pursuit of improved adherence assessment methods.

Purpose: Diffusion weighted MRI (DWI) is a promising imaging technique for early prediction of tumor response to radiation therapy. A recently proposed longitudinal DWI strategy using a Co-60 MRI guided RT system (MRIgRT) may bring functional MRI guided adaptive radiation therapy closer to clinical utility. We report our preliminary results of using this longitudinal DWI approach performed on the MRIgRT system for predicting the response of sarcoma patient to preop RT. Methods: Three sarcoma patients who underwent fractionated IMRT were recruited in this study. For all three patients DWI images were acquired immediately following his/her treatment. For each imaging session, ten slices were acquired interleaved with the b values covering the gross tumor volume (GTV). The diffusion images were processed to obtain the ADC maps using standard exponential fitting for each voxel. Regions of interest were drawn in the tumor on the diffusion images based on each patient’s clinical GTV contours. Each patient subsequently underwent surgery and the tumor necrosis score was available from standard pathology. The ADC values for each patient were compared to the necrosis scores to assess the predictive value of our longitudinal DWI for tumor response. Results: Each patient underwent 3 to 5 diffusion MRI scans depending on their treatment length. Patient 1 had a relatively unchanged ADC during the course of RT and a necrosis score of 30% at surgery. For patient 2, the mean ADC values decreased from 1.56 × 10-3 to 1.12 × 10-3 mm2/s and the patient’s necrosis score was less than 10%. Patient 3 had a slight increase in the ADC values from 0.59 × 10-3 to 0.71 × 10-3 mm2/s and patient’s necrosis score was 50%. Conclusion: Based on limited data from 3 patients, our longitudinal changes in tumor ADC assessed using the MRIgRT system correlated well with pathology results.

Pharmacological treatment and BBB-targeted genetic therapy for MCT8-dependent hypomyelination in zebrafish

Full Text Available Hypomyelination is a key symptom of Allan-Herndon-Dudley syndrome (AHDS, a psychomotor retardation associated with mutations in the thyroid-hormone (TH transporter MCT8 (monocarboxylate transporter 8. AHDS is characterized by severe intellectual deficiency, neuromuscular impairment and brain hypothyroidism. In order to understand the mechanism for TH-dependent hypomyelination, we developed an mct8 mutant (mct8−/− zebrafish model. The quantification of genetic markers for oligodendrocyte progenitor cells (OPCs and mature oligodendrocytes revealed reduced differentiation of OPCs into oligodendrocytes in mct8−/− larvae and adults. Live imaging of single glial cells showed that the number of oligodendrocytes and the length of their extensions are reduced, and the number of peripheral Schwann cells is increased, in mct8−/− larvae compared with wild type. Pharmacological analysis showed that TH analogs and clemastine partially rescued the hypomyelination in the CNS of mct8−/− larvae. Intriguingly, triiodothyronine (T3 treatment rescued hypomyelination in mct8−/− embryos before the maturation of the blood–brain barrier (BBB, but did not affect hypomyelination in older larvae. Thus, we expressed Mct8-tagRFP in the endothelial cells of the vascular system and showed that even relatively weak mosaic expression completely rescued hypomyelination in mct8−/− larvae. These results suggest potential pharmacological treatments and BBB-targeted gene therapy that can enhance myelination in AHDS and possibly in other TH-dependent brain disorders.

) system through Missions of General Interest and Support to Contracting (MIGAC). For minimally manipulated cells, four different funding processes are applicable, depending on the type of activity: (1) inclusion in a DRG; (2) inclusion in the list of products and services qualifying for reimbursement (LPPR) (as a medical device); (3) an annual lump sum provided by regional health agencies; and (4) a financial allowance under Missions of General Interest (MIG). Cell therapy is a diverse and promising category of medical interventions. Its heterogeneity and complexity mean that several funding options and market access pathways apply. The main challenges facing cell therapies relate to (1) the identification of the most appropriate path to reimbursement, and (2) price setting, whereas high manufacturing costs of these therapies will dictate a high price that could only be achieved by a product that leads to important additional patient benefits compared to available treatment options. More specific funding options could emerge as the number of cell therapies increases and the authorities face the need to structure and stabilise funding. It will be vital for manufacturers to have a clear understanding of the various temporary funding opportunities early in a product's lifecycle for the adoption of a stepwise approach to secure permanent funding. Furthermore, due to the very limited Health Technology Assessment (HTA) bodies experience for cell therapies, manufacturers should enter into dialogues with HTA agencies at an early stage to optimise market access conditions.

Local tumor recurrence and distant tumor metastasis frequently occur after radiation therapy and result in the death of cancer patients. These problems are caused, at least in part, by a tumor-specific oxygen-poor microenvironment, hypoxia. Oxygen-deprivation is known to inhibit the chemical ionization of both intracellular macro-molecules and water, etc., and thus reduce the cytotoxic effects of radiation. Moreover, DNA damage produced by free radicals is known to be more repairable under hypoxia than normoxia. Hypoxia is also known to induce biological tumor radioresistance through the activation of a transcription factor, hypoxia-inducible factor 1 (HIF-1). Several potential strategies have been devised in radiation therapy to overcome these problems; however, they have not yet achieved a complete remission. It is essential to reveal the intratumoral localization and dynamics of hypoxic/HIF-1-active tumor cells during tumor growth and after radiation therapy, then exploit the information to develop innovative therapeutic strategies, and finally damage radioresistant cells. In this review, we overview problems caused by hypoxia/HIF-1-active cells in radiation therapy for cancer and introduce strategies to assess intratumoral hypoxia/HIF-1 activity

Cannabis is the most commonly used illicit drug; a substantial minority of users develop dependence. The current lack of pharmacological treatments for cannabis dependence warrants the use of novel approaches and further investigation of promising pharmacotherapy. In this case series, we assessed the use of self-titrated dosages of Sativex (1:1, Δ-tetrahydrocannabinol [THC]/cannabidiol [CBD] combination) and motivational enhancement therapy and cognitive behavioral therapy (MET/CBT) for the treatment of cannabis dependence among 5 treatment-seeking community-recruited cannabis-dependent subjects. Participants underwent a 3-month open-label self-titration phase with Sativex (up to 113.4 of THC/105 mg of CBD) and weekly MET/CBT, with a 3-month follow-up. Sativex was well-tolerated by all participants (average dosage 77.5 THC/71.7 mg CBD). The combination of Sativex and MET/CBT reduced the amount of cannabis use and progressively reduced craving and withdrawal scores. THC/CBD metabolite concentration indicated reduced cannabis use and compliance with medication. In summary, this pilot study found that with Sativex in combination with MET/CBT reduced cannabis use while preventing increases in craving and withdrawal in the 4 participants completing the study. Further systematic exploration of Sativex as a pharmacological treatment option for cannabis dependence should be performed.

Full Text Available Randomised Controlled Trials (RCTs have shown the efficacy of CBTp, however few studies have considered its long-term effectiveness in routine services. This study reports the outcomes of clients seen in a psychological therapies clinic, set up following positive results obtained from an RCT (Peters et al. 2010. The aims were to evaluate the effectiveness of CBTp, using data from the service’s routine assessments for consecutive referrals over a 12 year period, and assess whether gains were maintained at a 6+ months’ follow-up. Of the 476 consenting referrals, all clients (N=358 who received ≥5 therapy sessions were offered an assessment at 4 time points (baseline, pre-, mid- and end of therapy on measures assessing current psychosis symptoms, emotional problems, general well-being and life satisfaction. A sub-set (N=113 was assessed at a median of 12 months after finishing therapy. Following the waiting list (median of 3 months clients received individualised, formulation-based CBTp for a median number of 19 sessions from 121 therapists with a range of experience receiving regular supervision. Clients showed no meaningful change on any measure while on the waiting list (Cohen’s d<=0.23. In contrast, highly significant improvements following therapy, all of which were significantly greater than changes during the waiting list, were found on all domains assessed (Cohen’s d: 0.44-0.75. All gains were maintained at follow-up (Cohen’s d: 0.29-0.82, with little change between end of therapy and follow-up (Cohen’s d<=0.18. Drop-out rate from therapy was low (13%. These results demonstrate the positive and potentially enduring impact of psychological therapy on a range of meaningful outcomes for clients with psychosis. The follow-up assessments were conducted on only a sub-set, which may not generalise to the full sample. Nevertheless this study is the largest of its kind in psychosis, and has important implications for the practice of

Objective: To assess the accuracy of isocentric rotation movement of Patient Positioning System (PPS) in fixed beam proton therapy. Methods: A 2 mm-diameter radioopaque sphere was positioned above the couch and was aligned to room iso-center (ISO). 11 PPS angles were selected to make isocentric rotation test respectively. The displacement of the sphere to ISO were measured and calculated by Digital Image Positioning System (DIPS) respectively when PPS reached each designed position. Totally four group measurements were repeated at different time. all data were collected and statistical analysis were performed. Results: The maximum shifts are (0.29 ± 0.05) mm, (0.21 ± 0.04) mm and (-0.21 ± 0.04) mm on X, Y, Z axes at - 110 degree PPS position, the absolute displacement of the sphere to ISO is (0.41 ± 0.07) mm(1SD). The minimum shifts are (-0.03 ± 0.05) mm, (0.05 ± 0.05) mm and (0.00 ± 0.00) mm on three principle axes at 30 degree PPS position, the absolute displacement of the sphere to ISO is (0.05 ± 0.06) mm. Conclusion: The isocentric rotation movement is the linchpin to realize multi-angle isocentric irradiation in fixed beamproton therapy. It is a complicated combined movement including PPS rotation and PPS translations. Since the high demand in the of precision of patient positioning, the accuracy of this combined movement played important role in proton therapy. In our tests, all shifts are less than 0.5 mm, can reach the requirement of positioning accuracy in proton therapy. (authors)

Radionuclide therapy is a promising modality for treatment of tumours of haematopoietic origin while the success for treatment of solid tumours so far has been limited. The authors consider radionuclide therapy mainly as a method to eradicate disseminated tumour cells and small metastases while bulky tumours and large metastases have to be treated surgically or by external radiation therapy. The promising therapeutic results for haematological tumours give hope that radionuclide therapy will have a breakthrough also for treatment of disseminated cells from solid tumours. New knowledge related to this is continuously emerging since new molecular target structures are being characterised and the knowledge on pharmacokinetics and cellular processing of different types of targeting agents increases. There is also improved understanding of the factors of importance for the choice of appropriate radionuclides with respect to their decay properties and the therapeutic applications. Furthermore, new methods to modify the uptake of radionuclides in tumour cells and normal tissues are emerging. However, we still need improvements regarding dosimetry and treatment planning as well as an increased knowledge about the tolerance doses for normal tissues and the radiobiological effects on tumour cells. This is especially important in targeted radionuclide therapy where the dose rates often are lower than 1 Gy/h

Experimental studies demonstrate that higher intake of omega-3 fatty acids (n-3 FA) improves insulin sensitivity, however, we reported that n-3 FA 2g therapy, most commonly used dosage did not significantly improve insulin sensitivity despite reducing triglycerides by 21% in patients. Therefore, we investigated the effects of different dosages of n-3 FA in patients with hypertriglyceridemia. This was a randomized, single-blind, placebo-controlled, parallel study. Age, sex, and body mass index were matched among groups. All patients were recommended to maintain a low fat diet. Forty-four patients (about 18 had metabolic syndrome/type 2 diabetes mellitus) in each group were given placebo, n-3 FA 1 (O1), 2 (O2), or 4 g (O4), respectively daily for 2 months. n-3 FA therapy dose-dependently and significantly decreased triglycerides and triglycerides/HDL cholesterol and improved flow-mediated dilation, compared with placebo (by ANOVA). However, each n-3 FA therapy did not significantly decrease high-sensitivity C-reactive protein and fibrinogen, compared with placebo. O1 significantly increased insulin levels and decreased insulin sensitivity (determined by QUICKI) and O2 significantly decreased plasma adiponectin levels relative to baseline measurements. Of note, when compared with placebo, each n-3 FA therapy did not significantly change insulin, glucose, adiponectin, glycated hemoglobin levels and insulin sensitivity (by ANOVA). We observed similar results in a subgroup of patients with the metabolic syndrome. n-3 FA therapy dose-dependently and significantly decreased triglycerides and improved flow-mediated dilation. Nonetheless, n-3 FA therapy did not significantly improve acute-phase reactants and insulin sensitivity in patients with hypertriglyceridemia, regardless of dosages. Copyright © 2014.

Background Opioid misuse is a large public health problem in the United States. Residents of rural areas and American Indian (AI) reservation/trust lands represent traditionally underserved populations with regard to substance-use-disorder therapy. Purpose Assess differences in the number of opioid agonist therapy (OAT) facilities and physicians with Drug Addiction Treatment Act (DATA) waivers for rural versus urban, and AI reservation/trust land versus non-AI reservation/trust land areas in Washington State. Methods The unit of analysis was the zip code. The dependent variables were the number of OAT facilities and DATA-waivered physicians in a region per 10,000 residents aged 18–64 in a zip code. A region was defined as a zip code and its contiguous zip codes. The independent variables were binary measures of whether a zip code was classified as rural versus urban, or AI reservation/trust land versus non-AI reservation/trust land. Zero-inflated negative binomial regressions with robust standard errors were estimated. Results The number of OAT clinics in a region per 10,000 zip-code residents was significantly lower in rural versus urban areas (P = .002). This did not differ significantly between AI reservation/trust land and non-AI reservation/trust land areas (P = .79). DATA-waivered physicians in a region per 10,000 zip-code residents was not significantly different between rural and urban (P = .08), or AI reservation/trust land versus non-AI reservation/trust land areas (P = .21). Conclusions It appears that the potential for Washington State residents of rural and AI reservation areas to receive OAT is similar to that of residents outside of those areas; however, difficulties in accessing therapy may remain, highlighting the importance of expanding health care insurance and providing support for DATA-waivered physicians.

Effective pharmacotherapies to treat methamphetamine (MA) dependence have not been identified, and behavioral therapies are marginally effective. Based on behavioral studies demonstrating the potential efficacy of aerobic exercise for improving depressive symptoms, anxiety, cognitive deficits, and substance use outcomes, the study described here is examining exercise as a potential treatment for MA-dependent individuals. This study is randomizing 150 participants with MA dependence at a residential treatment facility for addictive disorders to receive either a thrice-weekly structured aerobic and resistance exercise intervention or a health education condition. Recruitment commenced in March, 2010. Enrollment and follow-up phases are ongoing, and recruitment is exceeding targeted enrollment rates. Seeking evidence for a possibly effective adjunct to traditional behavioral approaches for treatment of MA dependence, this study is assessing the ability of an 8-week aerobic and resistance exercise protocol to reduce relapse to MA use during a 12-week follow-up period after discharge from residential-based treatment. The study also is evaluating improvements in health and functional outcomes during and after the protocol. This paper describes the design and methods of the study. Copyright © 2013 Elsevier Inc.

In Japan, methamphetamine (MAP) abuse has been a serious problem for 60 years, and many of MAP abusers have been incarcerated in prisons as a violator of the Stimulant Control Law in Japan. The purpose of the present study is to evaluate effectiveness of the relapse prevention guidance for drug-dependent inmates using a self-teaching workbook for drug-abusing adolescents and group therapy, conducted in the Harima Rehabilitation Program Center, one of the new prisons which the Ministry of Justice founded cooperating private enterprises as a "Private Finance Initiative" project. We provided for 89 male drug-dependent inmates, incarcerated in the Harima Rehabilitation Program Center, with the relapse prevention guidance consisting of a self-teaching workbook and group therapy, and implement pre-and post-evaluations by the Self-efficacy Scale for Drug Dependence (SES) and the Stages of Change Readiness and Treatment Eagerness Scale, 8th version for Drug Dependence (SOCRATES-8D). After a waiting term, the participants were provided with a self-teaching program, subsequently with a group program. At the point of completing the waiting term, no significant changes were observed in the SES and SOCRATES-8D scores. However, at the point of completing the self-teaching program, the SES scores significantly fell, while the total SOCRATES-8D score and the scores of the two subscales, the "Recognition" and "Ambivalence," significantly rose. Further, at the point of completing the group program, the total scores of the SES and SOCRATES-8D, and the score of the two SOCRATES-8D subscales, the "Recognition" and "Taking Steps," significantly rose. The relapse prevention guidance consisting of a self-teaching workbook and group therapy, conducted in the Harima Rehabilitation Program Center, were supposed to bring same internal changes as the "Stage of Changes" model, proposed by Prochaska and DiClemente, to drug-dependent inmates.

This study compared Female-Specific Cognitive Behavioral Therapy (FS-CBT) to evidence-based, gender-neutral CBT (GN-CBT; Epstein & McCrady, 2009) for women with alcohol use disorder (AUD). Women (N = 99) with AUD, mean age 48, were randomly assigned to 12 outpatient manual-guided sessions of FS-CBT (n = 44) or GN-CBT (n = 55). Women were assessed at baseline and 3, 9 and 15 months after baseline for drinking and for specific issues common among women with AUD. A FS-CBT protocol was developed that was discriminable on treatment integrity ratings from GN-CBT. No treatment condition differences were found in treatment engagement, changes in drinking, alcohol-related coping, abstinence self-efficacy, motivation to change, or constructs directly targeted in FS-CBT (sociotropy, autonomy, depression, anxiety). Women in both conditions were highly engaged and satisfied with treatment, and reported significant reductions in drinking and changes in desired directions for all other variables except social support for abstinence. In the year following treatment, women in the FS-CBT but not in the CBT condition reported an increase in percentage of abstainers in their social networks (0.69% per month, SE = 0.21, p = .002). The value and appeal of female-specific programming in AUD treatment has been established in the wider literature (Epstein & Menges, 2013), and the current study provides support for the use of the Female-Specific Cognitive Behavioral Therapy (FS-CBT) manual as an option that may yield outcomes similar to standard gender-neutral CBT for women with AUD. Future research should examine whether FS-CBT enhances treatment utilization for women. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

This pilot study assessed the feasibility of incorporating animal-assisted therapy teams (ATT) into a 6-week group exercise program for older adults (77 ± 6 years). Fifteen participants were randomly assigned to an exercise with ATT (E+ATT; n = 8) or exercise only (E; n = 7) group. Groups exercised 3x/week for 45 min. Feasibility was assessed by three objectives: (1) ATT will not need extensive preparation beyond their original therapy training; (2) the study will require minimal cost; and (3) ATT must not impair the effectiveness of the exercise program. By the study conclusion, all objectives were met. Time and cost were minimal for ATT, and adherence was 93% and 90% for E+ATT and E, respectively. There were significant improvements in both groups (p ≤ .05) for arm curls, get-up and go, and 6-min walk. The results of this pilot study suggest that it is feasible to incorporate ATT into group exercise programming for older adults.

Moffett, L A; Steinberg, S L; Rohde, P

1996-01-01

The design and implementation of a personality assessment system for severely substance-dependent men in a therapeutic community (TC) are described. The system was designed from a treatment utility perspective (Hayes, Nelson, & Jarrett, 1987) and uses the Personality Research Form E (Jackson, 1984) to provide each patient with feedback (a) describing his normal personality traits, (b) predicting his probable pattern of adjustment to the treatment setting, and (c) prescribing specific actions he can take to address potentially problematic behaviors. Discussing the the results with the patient helps him cope with the TC. Reviewing the assessment results with the staff promotes their empathy for the patient as a person whose behavior can be understood as an interaction of his personality with the specific demands of the TC rather than seeing the patient in exclusively pathological terms. Specific suggestions for behavior change guide both the patient and the staff and are potentially useful in various treatment settings.

This study investigated the process of change by modeling transitions among four clinical states encountered in 64 detoxified opiate-dependent individuals treated with daily oral naltrexone: no opiate use, blocked opiate use (i.e., opiate use while adhering to oral naltrexone), unblocked opiate use (i.e., opiate use after having discontinued oral naltrexone), and treatment dropout. The effects of baseline characteristics and two psychosocial interventions of differing intensity, behavioral naltrexone therapy (BNT) and compliance enhancement (CE), on these transitions were studied. Participants using greater quantities of opiates were more likely than other participants to be retained in BNT relative to CE. Markov modeling indicated a transition from abstinence to treatment dropout was approximately 3.56 times greater among participants in CE relative to participants in BNT, indicating the more comprehensive psychosocial intervention kept participants engaged in treatment longer. Transitions to stopping treatment were more likely to occur after unblocked opiate use in both treatments. Continued opiate use while being blocked accounted for a relatively low proportion of transitions to abstinence and may have more deleterious effects later in a treatment episode.

Dysphagia is common in dependent older adults. Thus, a method of evaluating eating and swallowing functions that can be used to diagnose and manage dysphagia in a simple and robust manner is required. In 2002, the Mann Assessment of Swallowing Ability (MASA) was introduced to identify dysphagia in acute-stage stroke patients. As the MASA enables easy screening, it might also be applicable to dependent older adults if appropriate MASA cut-off values and the most useful assessment items could be determined. In the present study, we attempted to determine suitable MASA cut-off values, and the most useful assessment items for predicting aspiration and pharyngeal retention in dependent older adults. Using the MASA, we evaluated the eating and swallowing functions of 50 dependent older adults with dysphagia. All of the patients also underwent videoendoscopic-based swallowing evaluations to detect aspiration and pharyngeal retention. The participants' characteristics and the utility of each assessment item were compared between various groups. Using the patients' videoendoscopic findings as a reference, receiver operating characteristic curve analysis was carried out to determine appropriate cut-off values for predicting aspiration and pharyngeal retention in dependent older adults. The optimal MASA cut-off values for predicting aspiration and pharyngeal retention were 122 points and 151 points, respectively. A total of 17 of the 24 clinical items assessed by the MASA were found to be associated with aspiration in dependent older adults. The MASA is a useful screening tool for evaluating eating and swallowing functions in dependent older adults. Geriatr Gerontol Int 2017; 17: 561-567. © 2016 Japan Geriatrics Society.

Development, prevention, and treatment of feeding tube dependency.

2017-06-01

Enteral nutrition is effective in ensuring nutritional requirements and growth. However, when tube feeding lasts for a longer period, it can lead to tube dependency in the absence of medical reasons for continuation of tube feeding. Tube-dependent children are unable or refuse to start oral activities and they lack oral skills. Tube dependency has health-, psychosocial-, and economy-related consequences. Therefore, the transition to oral feeding is of great importance. However, this transition can be very difficult and needs a multidisciplinary approach. Most studies for treatment of tube dependency are based on behavioral interventions, such as family therapy, individual behavior therapy, neuro-linguistic programming, and parental anxiety reduction. Furthermore, oral motor therapy and nutritional adjustments can be helpful in tube weaning. The use of medication has been described in the literature. Although mostly chosen as the last resort, hunger-inducing methods, such as the Graz-model and the Dutch clinical hunger provocation program, are also successful in weaning children off tube feeding. The transition from tube to oral feeding is important in tube-dependent children but can be difficult. We present an overview for the prevention and treatment of tube dependency. What is known: • Longer periods of tube feeding can lead to tube dependency. • Tube weaning can be very difficult. What is new: • Weaning as soon as possible and therefore referral to a multidisciplinary team are recommended. • An overview of treatment options for tube dependency is presented in this article.

The primary aim was to investigate the comparative effects of massage therapy and exercise therapy on patients with multiple sclerosis. The secondary aim was to investigate whether combination of both massage and exercise has an additive effect. Randomized controlled pilot trial with repeated measurements and blinded assessments. Local Multiple Sclerosis Society. A total of 48 patients with multiple sclerosis were randomly assigned to four equal subgroups labelled as massage therapy, exercise therapy, combined massage-exercise therapy and control group. The treatment group received 15 sessions of supervised intervention for five weeks. The massage therapy group received a standard Swedish massage. The exercise therapy group was given a combined set of strength, stretch, endurance and balance exercises. Patients in the massage-exercise therapy received a combined set of massage and exercise treatments. Patients in the control group were asked to continue their standard medical care. Pain, fatigue, spasticity, balance, gait and quality of life were assessed before and after intervention. Massage therapy resulted in significantly larger improvement in pain reduction (mean change 2.75 points, P = 0.001), dynamic balance (mean change, 3.69 seconds, P = 0.009) and walking speed (mean change, 7.84 seconds, P = 0.007) than exercise therapy. Patients involved in the combined massage-exercise therapy showed significantly larger improvement in pain reduction than those in the exercise therapy (mean change, 1.67 points, P = 0.001). Massage therapy could be more effective than exercise therapy. Moreover, the combination of massage and exercise therapy may be a little more effective than exercise therapy alone.

Available occupational therapy assessment scales focus on specific areas of functioning. There is a need for comprehensive evaluation of diverse aspects of functioning in people with mental illness. To develop a comprehensive assessment scale to evaluate diverse aspects of functioning among people with mental illness and to assess its validity and reliability. Available instruments, which evaluate diverse aspects of functioning in people with mental illness, were retrieved. Relevant items, which evaluate specific functions, were selected by a committee of mental health experts and combined to form a comprehensive instrument. Face and content validity and feasibility were assessed and the new instrument was piloted among 60 patients with mental illness. The final version of the instrument was employed in 151 consecutive clients, between 18 and 60 years of age, who were also assessed using Global Assessment of Functioning (GAF), Occupational Therapy Task Observation Scale (OTTOS), Social Functioning Questionnaire (SFQ), Rosenberg Self Esteem Scale (RSES) and Pai and Kapur Family Burden Interview Schedule (FBIS) by two therapists. The inter-rater reliability and test-retest reliability of the new instrument (Vellore Occupational Therapy Evaluation Scale (VOTES)) were also evaluated. The new scale had good internal consistency (Cronbach's alpha = .817), inter-rater reliability .928 (.877-.958) and test-retest reliability .928 (.868-.961). The correlation between the general behaviour domain (Pearson's Correlation Coefficient [PCC] = -.763, p = .000), task behaviour (PCC = -.829, p = .000), social skills (PCC = -.351, p = .000), intrapersonal skills (PCC = -.208, p = .010), instrumental activities of daily living (IADL) (PCC = -.329, p = .038) and leisure activities (PCC = -.433, p = .005) scores of VOTES with the corresponding domains in the scales used for comparison was statistically significant.

Morphology Dependent Assessment of Resilience for Urban Areas

Directory of Open Access Journals (Sweden)

Kai Fischer

2018-05-01

Full Text Available The formation of new threats and the increasing complexity of urban built infrastructures underline the need for more robust and sustainable systems, which are able to cope with adverse events. Achieving sustainability requires the strengthening of resilience. Currently, a comprehensive approach for the quantification of resilience of urban infrastructure is missing. Within this paper, a new generalized mathematical framework is presented. A clear definition of terms and their interaction builds the basis of this resilience assessment scheme. Classical risk-based as well as additional components are aligned along the timeline before, during and after disruptive events, to quantify the susceptibility, the vulnerability and the response and recovery behavior of complex systems for multiple threat scenarios. The approach allows the evaluation of complete urban surroundings and enables a quantitative comparison with other development plans or cities. A comprehensive resilience framework should cover at least preparation, prevention, protection, response and recovery. The presented approach determines respective indicators and provides decision support, which enhancement measures are more effective. Hence, the framework quantifies for instance, if it is better to avoid a hazardous event or to tolerate an event with an increased robustness. An application example is given to assess different urban forms, i.e., morphologies, with consideration of multiple adverse events, like terrorist attacks or earthquakes, and multiple buildings. Each urban object includes a certain number of attributes, like the object use, the construction type, the time-dependent number of persons and the value, to derive different performance targets. The assessment results in the identification of weak spots with respect to single resilience indicators. Based on the generalized mathematical formulation and suitable combination of indicators, this approach can quantify the

Modification of empirical antimicrobials when warranted by culture results or clinical signs is recommended to control antimicrobial overuse and resistance. We aimed to assess the frequency with which patients were started on empirical antimicrobials, characteristics of the empirical regimen and the clinical characteristics of patients at the time of starting antimicrobials, patterns of changes to empirical therapy at different timepoints, and modifiable factors associated with changes to the initial empirical regimen in the first 5 days of therapy. We did a chart review of adult inpatients receiving one or more antimicrobials in six US hospitals on 4 days during 2009 and 2010. Our primary outcome was the modification of antimicrobial regimen on or before the 5th day of empirical therapy, analysed as a three-category variable. Bivariate analyses were used to establish demographic and clinical variables associated with the outcome. Variables with p values below 0·1 were included in a multivariable generalised linear latent and mixed model with multinomial logit link to adjust for clustering within hospitals and accommodate a non-binary outcome variable. Across the six study sites, 4119 (60%) of 6812 inpatients received antimicrobials. Of 1200 randomly selected patients with active antimicrobials, 730 (61%) met inclusion criteria. At the start of therapy, 220 (30%) patients were afebrile and had normal white blood cell counts. Appropriate cultures were collected from 432 (59%) patients, and 250 (58%) were negative. By the 5th day of therapy, 12·5% of empirical antimicrobials were escalated, 21·5% were narrowed or discontinued, and 66·4% were unchanged. Narrowing or discontinuation was more likely when cultures were collected at the start of therapy (adjusted OR 1·68, 95% CI 1·05-2·70) and no infection was noted on an initial radiological study (1·76, 1·11-2·79). Escalation was associated with multiple infection sites (2·54, 1·34-4·83) and a positive

Time-dependent reliability analysis and condition assessment of structures

International Nuclear Information System (INIS)

Ellingwood, B.R.

1997-01-01

Structures generally play a passive role in assurance of safety in nuclear plant operation, but are important if the plant is to withstand the effect of extreme environmental or abnormal events. Relative to mechanical and electrical components, structural systems and components would be difficult and costly to replace. While the performance of steel or reinforced concrete structures in service generally has been very good, their strengths may deteriorate during an extended service life as a result of changes brought on by an aggressive environment, excessive loading, or accidental loading. Quantitative tools for condition assessment of aging structures can be developed using time-dependent structural reliability analysis methods. Such methods provide a framework for addressing the uncertainties attendant to aging in the decision process

Fast neutron therapy began as long ago as 1938 and subsequently proton, alpha particle, heavy ion, pion and neutron capture therapy have been used. To date it is estimated that in excess of 45000 people have undergone some form of hadron therapy. In the future it is expected that fast neutron therapy will be used for selected tumour types for which neutron are known to show improved cure rates. The future trends in charged particle therapy will be driven by increasing commercialization. The future of neutron capture therapy will depend on current clinical trials with epithermal neutron beams and the development of new tumour-seeking drugs

Glover, N M

1999-06-01

This article discusses the use of play therapy and art therapy treatment techniques for persons in substance abuse treatment who have a history of incest victimization. While substance abuse treatment focuses on substance abuse, neglecting to address issues related to past incest contact may increase the potential for relapse. This population displays unique characteristics that may prevent them from participating in, or benefitting from, traditional treatment modalities (which are highly dependent upon the verbal interactions between clients and therapists). Play therapy and art therapy are discussed in terms of history, rationale, and benefits to clients.

Acromegaly is known to affect peripheral nervous system (PNS) causing carpal tunnel syndrome (CTS) and polyneuropathy. The frequency of these disorders and the evaluation methods vary among studies. In the present study, we aimed to examine PNS of acromegaly patients under somatostatin analogue (SSA) therapy. Forty-eight acromegaly patients (26 F/22 M, 45.58 ± 11.6 years) under SSA treatment and 44 healthy controls (25 F/19 M, 47.46 ± 8.7 years) were assessed by symptom questionnaires, neurologic examination and electrophysiological studies. 87.5 % of the acromegaly patients had at least one abnormal finding regarding PNS. With the incorporation of palm-wrist median nerve conduction velocity method, we detected CTS in 50 % of patients. Polyneuropathy was less frequent (29.2 %). Both conditions were independent from the coexisting diabetes mellitus (p = 0.22 for CTS, p = 0.71 for polyneuropathy). Polyneuropathy but not CTS was more common among biochemically uncontrolled acromegaly patients rather than those under control (p = 0.03; p = 0.68, respectively). Our findings emphasize the high prevalence of peripheral nervous system involvement in acromegaly patients under SSA therapy and importance of neurological evaluation of these patients. Early diagnosis and treatment of the disease may reduce the PNS involvement.

Modelling and assessment of dependent performance shaping factors through Analytic Network Process

International Nuclear Information System (INIS)

De Ambroggi, Massimiliano; Trucco, Paolo

2011-01-01

Despite continuous progresses in research and applications, one of the major weaknesses of current HRA methods dwells in their limited capability of modelling the mutual influences between performance shaping factors (PSFs). Indeed at least two types of dependencies between PSFs can be defined: (i) dependency between the states of the PSFs; (ii) dependency between the influences (impacts) of the PSFs on the human performance. This paper introduces a method, based on Analytic Network Process (ANP), for the quantification of the latter, where the overall contribution of each PSF (weight) to the human error probability (HEP) is eventually returned. The core of the method is the modelling process, articulated into two steps: firstly, a qualitative network of dependencies between PSFs is identified, then, the importance of each PSF is quantitatively assessed using ANP. The model allows to distinguish two components of the PSF influence: direct influence that is the influence that the considered PSF is able to express by itself, notwithstanding the presence of other PSFs and indirect influence that is the incremental influence of the considered PSF through its influence on other PSFs. A case study in Air Traffic Control is presented where the proposed approach is integrated into the cognitive simulator PROCOS. The results demonstrated a significant modification of the influence of PSFs over the operator performance when dependencies are taken into account, underlining the importance of considering not only the possible correlation between the states of PSFs but also their mutual dependency in affecting human performance in complex systems.

Nasopharyngeal carcinoma (NPC) is mainly treated by radiation therapy. A common complication of radiotherapy is xerostomia. Direct measurements of the amount of saliva produced using suction cups and volumetric assessments are cumbersome and time consuming. Sequential radionuclide sialography is a reproducible and convenient method of measuring salivary function. Patients with newly diagnosed NPC underwent a pilot study using technetium-99m pertechnetate sequential radionuclide sialography to assess their salivary function before and at 3 months post radiation therapy. From the sialography, time-activity-curves were obtained for analysis of salivary function. The shape of the time-activity-curve with citric acid stimulation was classified into 4 types according to the degree of radiation-induced dysfunction. All 14 patients had worse time-activity curves for both parotids and submandibular glands after radiation therapy. The P values for the change in time-activity-curves for all the salivary glands were less than 0.005. All patients with abnormal type of curves before radiation therapy presented type IV(non-functioning) curve after radiation therapy. A ratio (Rc) of pre- and post-stimulation counts allowed for quantification of the degree of stimulatory response. We found a significant decrease in Rc before and after radiation therapy for all the salivary glands (P < 0.001). The salivary gland to background ratio, which is a reflection of the degree of salivary gland functional uptake, also had a significant reduction after radiation. It is feasible to use technetium 99m pertechnetate in the measurement of salivary gland function in nasopharyngeal cancer patients treated with radiation therapy

Infidelity is an often cited problem for couples seeking therapy, but the research literature to date is very limited on couple therapy outcomes when infidelity is a problem. The current study is a secondary analysis of a community-based sample of couple therapy in Germany and Austria. Outcomes for 145 couples who reported infidelity as a problem in their relationship were compared with 385 couples who sought therapy for other reasons. Analyses based on hierarchical linear modeling revealed that infidelity couples were significantly more distressed and reported more depressive symptoms at the start of therapy but continued improving through the end of therapy and to 6 months posttherapy. At the follow-up assessment, infidelity couples were not statistically distinguishable from non-infidelity couples, replicating previous research. Sexual dissatisfaction did not depend on infidelity status. Although there was substantial missing data, sensitivity analyses suggested that the primary findings were not due to missing data. The current findings based on a large community sample replicated previous work from an efficacy trial and show generally optimistic results for couples in which there has been an affair. 2010 APA, all rights reserved

This chapter first summarizes the therapy of addiction disorder, and elaborates on the progress of medication. First, the difference between dependency and addiction are introduced. The basic principles of the therapy of substance and non-substance addiction are then put forward. It is also pointed out in this chapter that with the progress of the study, the goal of addiction disorder therapy is expected to transfer from reducing the relapse and harm of the addiction to completely eliminating and recovering from it. This chapter also introduces the progress of psychological addiction elimination technology, especially the "Unconditioned Stimulus Retrieval Extinction Paradigm and Conditioned Stimulus Retrieval Extinction Paradigm" and PITDH technology. Finally it is pointed out that in addiction disorder therapy, comprehensive intervention has become a trend. With regard to the medication for addiction disorders, this chapter also includes the progress and deficiencies of substance and non-substance addiction. In terms of addiction disorder rehabilitation, the foundation of substance addiction is medication which is, however, limited for non-substance addiction. The key to the rehabilitation of addiction disorder is psycho-behavioral therapy, which is especially effective in eliminating craving.

Stroke is the main cause of disability in high-income countries and ranks second as a cause of death worldwide. Infections occur frequently after stroke and may adversely affect outcome. Preventive antibiotic therapy in the acute phase of stroke may reduce the incidence of infections and improve outcome. In the previous version of this Cochrane Review, published in 2012, we found that antibiotics did reduce the risk of infection but did not reduce the number of dependent or deceased patients. However, included studies were small and heterogeneous. In 2015, two large clinical trials were published, warranting an update of this Review. To assess the effectiveness and safety of preventive antibiotic therapy in people with ischaemic or haemorrhagic stroke. We wished to determine whether preventive antibiotic therapy in people with acute stroke:• reduces the risk of a poor functional outcome (dependency and/or death) at follow-up;• reduces the occurrence of infections in the acute phase of stroke;• reduces the occurrence of elevated body temperature (temperature ≥ 38° C) in the acute phase of stroke;• reduces length of hospital stay; or• leads to an increased rate of serious adverse events, such as anaphylactic shock, skin rash, or colonisation with antibiotic-resistant micro-organisms. We searched the Cochrane Stroke Group Trials Register (25 June 2017); the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 5; 25 June 2017) in the Cochrane Library; MEDLINE Ovid (1950 to 11 May 2017), and Embase Ovid (1980 to 11 May 2017). In an effort to identify further published, unpublished, and ongoing trials, we searched trials and research registers, scanned reference lists, and contacted trial authors, colleagues, and researchers in the field. Randomised controlled trials (RCTs) of preventive antibiotic therapy versus control (placebo or open control) in people with acute ischaemic or haemorrhagic stroke.

Breast conserving therapy generally is considered to be a safe alternative to mastectomy in a large proportion of operable breast cancer patients. Small tumor size, wide excisions, absence of vascular invasion and of extensive intraductal component are prognosticators for therapy success. Good results depend on technique and on patient selection. For some tumor situations specific therapy modifications are under investigation. (author)

To investigate dynamic change of serum receptor and antibody of thyrotrophic anti- body (TRAb) and its prognosis value after a one-off successful therapy on Graves disease with 131 I, 257 Graves disease patients were treated with one dose of 131 I therapy. 175 of them with average age of 40 (43 male and 132 female patients) were cured. The 131 I activity given to patients was 207.2±66. 6 MBq. The serum levels of TRAb were determined once every three months before and after 131 I therapy. The results showed that the serum TRAb levels in all patients were positive before 131 I therapy. The serum TRAb levels in 60. 6% of patients were raised once, and then reduced to normal, The serum levels of TRAb in 16.0% of patients were remained high or reduce slowly, and the clinical symptom was improved slowly, but these patients didn't recrudesce. The TRAb levels in 9.7% of patients decreased continually, their prognosis was well. The TRAb levels in 13.7% of patients were raised twice after the therapy, and appear hypothyroidism. The detection of dynamic changes of serum TRAb levels in Graves disease patients may be useful in assessing prognosis after 131 I therapy. (authors)

2012-01-01

Full Text Available Ocular gene therapy is rapidly becoming a reality. By November 2012, approximately 28 clinical trials were approved to assess novel gene therapy agents. Viral infections such as herpetic keratitis caused by herpes simplex virus 1 (HSV-1 can cause serious complications that may lead to blindness. Recurrence of the disease is likely and cornea transplantation, therefore, might not be the ideal therapeutic solution. This paper will focus on the current situation of ocular gene therapy research against herpetic keratitis, including the use of viral and nonviral vectors, routes of delivery of therapeutic genes, new techniques, and key research strategies. Whereas the correction of inherited diseases was the initial goal of the field of gene therapy, here we discuss transgene expression, gene replacement, silencing, or clipping. Gene therapy of herpetic keratitis previously reported in the literature is screened emphasizing candidate gene therapy targets. Commonly adopted strategies are discussed to assess the relative advantages of the protective therapy using antiviral drugs and the common gene therapy against long-term HSV-1 ocular infections signs, inflammation and neovascularization. Successful gene therapy can provide innovative physiological and pharmaceutical solutions against herpetic keratitis.

Full Text Available Background. Granulocyte-monocyte apheresis has been proposed for the treatment of ulcerative colitis, although it is limited by costs and variability of results. Aim. To assess effectiveness of granulocyte-monocyte apheresis in patients with steroid-dependent, azathioprine-intolerant/resistant moderate ulcerative colitis. Methods. Consecutive patients fulfilling inclusion criteria were prospectively enrolled, treated by apheresis, and followed up for 12 months. The primary end point of the study was steroid-free clinical remission at 12 months, with no need for biologic therapy or surgery. Results. From January to December 2013, 33 patients were enrolled. After one year of follow-up, 12 (36% patients had clinical remission, were steroid-free, and had no need for biological therapy or surgery; 3 (9% cases showed a clinical response (but not clinical remission. Moreover, 12 (36% patients required biologic therapy, 4 (12% underwent colectomy, and in the other 2 (6% a reduction, but not withdrawal, of steroid dose was achieved. Conclusions. Our study shows that a standard course of granulocyte-monocyte apheresis is associated with a 36% steroid-free clinical remission in patients with steroid-dependent, azathioprine-intolerant or resistant moderate ulcerative colitis. Apheresis might represent an alternative to biologic therapy or surgery in this specific subgroup of patients. This trial is registered with Clinicaltrial.gov NCT03189888.

Biofeedback therapy has been reported to be effective in the treatment of migraine. However, previous studies have assessed its effectiveness using paper-and-pencil diaries, which are not very reliable. The objective of the present pilot study was to investigate the feasibility of using computerized ecological momentary assessment (EMA) for evaluating the efficacy of BF treatment for migraine in a randomized controlled trial. The subjects comprised one male and 26 female patients with migraine. They were randomly assigned to either biofeedback or wait-list control groups. Patients were asked to carry a palmtop-type computer to record momentary symptoms for 4 weeks before and after biofeedback treatment. The primary outcome measure was headache intensity. The secondary outcome measures included psychological stress, anxiety, irritation, headache-related disability and the frequency (number of days per month) of migraine attack and of headache of at least moderate intensity (pain rating ≥50). Headache intensity showed significant main effects of period (before vs. after therapy, p = 0.02) and group (biofeedback vs. control groups, p = 0.42) and a significant period × group interaction (p Biofeedback reduced the duration of headaches by 1.9 days, and the frequency of days when headache intensity was ≥50 by 2.4 times. In addition, headache-related disability, psychological stress, depression, anxiety, and irritation were significantly improved. The present study used computerized EMA to show that biofeedback could improve the symptoms of migraine, including psychological stress and headache-related disability.

In human medicine radiosynorviorthesis (RSO) is anestablished form of therapy in chronic inflammatory or active degenerative joint disease. Chronic lameness in dogs as a result of joint disease is a common problem. This study was carried out to establish the role of RSO in chronic inflammatory or active degenerative joint disease in dogs. In 33 dogs with 51 joints with ostearthritis RSO was performed. Before treatment a classification of 4 grades of lameness was determined in each dog. 4 weeks and 7 months later a new assessment considering this classification was performed to determine the change of lameness grade. Improvement of lameness was found in 43-75%. of joints, the improvement was dependent on grade of synovitic activity before therapy. There were no side effects observed. The dogs with distinct effusion and the dogs which responded well to intraarticulary steroid injection before-hand, showed the best results. In these dogs RSO lead to obvious prolonged lamefree intervalls and a marked reduction of pain medication and therefore to a better quality of life. (orig.)

Purpose: Although the likelihood of radiation-related adverse events influences treatment decisions regarding radiation therapy after prostatectomy for eligible patients, the data available to inform decisions are limited. This study was designed to evaluate the genitourinary, gastrointestinal, and sexual adverse events associated with postprostatectomy radiation therapy and to assess the influence of radiation timing on the risk of adverse events. Methods: The Regione Emilia-Romagna Italian Longitudinal Health Care Utilization Database was queried to identify a cohort of men who received radical prostatectomy for prostate cancer during 2003 to 2009, including patients who received postprostatectomy radiation therapy. Patients with prior radiation therapy were excluded. Outcome measures were genitourinary, gastrointestinal, and sexual adverse events after prostatectomy. Rates of adverse events were compared between the cohorts who did and did not receive postoperative radiation therapy. Multivariable Cox proportional hazards models were developed for each class of adverse events, including models with radiation therapy as a time-varying covariate. Results: A total of 9876 men were included in the analyses: 2176 (22%) who received radiation therapy and 7700 (78%) treated with prostatectomy alone. In multivariable Cox proportional hazards models, the additional exposure to radiation therapy after prostatectomy was associated with increased rates of gastrointestinal (rate ratio [RR] 1.81; 95% confidence interval [CI] 1.44-2.27; P<.001) and urinary nonincontinence events (RR 1.83; 95% CI 1.83-2.80; P<.001) but not urinary incontinence events or erectile dysfunction. The addition of the time from prostatectomy to radiation therapy interaction term was not significant for any of the adverse event outcomes (P>.1 for all outcomes). Conclusion: Radiation therapy after prostatectomy is associated with an increase in gastrointestinal and genitourinary adverse events. However

To systematically review and assess the quality of cost-effectiveness analyses (CEAs) of pharmaceutical therapies for metastatic colorectal cancer (mCRC). The MEDLINE, EMBASE, Cochrane, and EconLit databases were searched for the Medical Subject Headings or text key words quality-adjusted, QALY, life-year gained (LYG), and cost-effectiveness (January 1, 1999-December 31, 2009). Original CEAs of mCRC pharmacotherapy published in English were included. CEAs that measured health effects in units other than quality-adjusted life years or LYG and letters to the editor, case reports, posters, and editorials were excluded. Each article was independently assessed by 2 trained reviewers according to a quality checklist created by the Panel on Cost-Effectiveness in Health and Medicine. Twenty-four CEA studies pertaining to pharmaceutical therapies for mCRC were identified. All studies showed a wide variation in methodologic approaches, which resulted in a different range of incremental cost-effectiveness ratios reported for each regimen. We found common methodologic flaws in a significant number of CEA studies, including lack of clear description for critique of data quality; lack of method for adjusting costs for inflation and methods for obtaining expert judgment; no results of model validation; wide differences in the types of perspective, time horizon, study design, cost categories, and effect outcomes; and no quality assessment of data (cost and effectiveness) for the interventions evaluation. This study has shown a wide variation in the methodology and quality of cost-effectiveness analysis for mCRC. Improving quality and harmonization of CEA for cancer treatment is needed. Further study is suggested to assess the quality of CEA methodology outside the mCRC disease state.

Growth hormone therapy for children born small for gestational age: height gain is less dose dependent over the long term than over the short term.

Approximately 3% of children are born small for gestational age (SGA), and approximately 10% of SGA children maintain a small body size throughout childhood and often into adult life. Among short SGA children, growth hormone (GH) therapy increases short-term growth in a dose-dependent manner; experience with long-term therapy is limited. To delineate the dose dependency of long-term height gain among short SGA children receiving GH therapy. We performed an epianalysis of the first adult height data for SGA children (n = 28) enrolled in 3 randomized trials comparing the growth-promoting efficacy of 2 continuous GH regimens (33 or 67 microg/kg per day for approximately 10 years, starting at approximately 5 years of age); in addition, we performed a meta-analysis of the adult height results published previously and those presented here. Epianalysis outcomes (n = 28) suggested that adult height increased more with a higher-dose regimen than with a lower-dose regimen. In the meta-analysis (n = 82), the higher-dose regimen was found to elicit a long-term height gain superior to that achieved with the lower-dose regimen by a mean of 0.4 SD (approximately 1 inch). Children who were shorter at the start of therapy experienced more long-term height gain. These findings confirm GH therapy as an effective and safe approach to reduce the adult height deficit that short SGA children otherwise face. In addition, the first meta-analysis indicated that height gain is less dose dependent over the long term than over the short term, at least within the dose range explored to date. For SGA children whose stature is not extremely short, current data support the use of a GH dose of approximately 33 microg/kg per day from start to adult height, particularly if treatment starts at a young age; shorter children (for example, height below -3 SD) might benefit from an approach in which short-term catch-up growth is achieved with a higher dose (> or =50 microg/kg per day) and long-term growth

Cupping therapy has been used in traditional Chinese medicine for thousands of years to relieve muscle pain/tendency/fatigue and to cure or reduce symbols of other diseases. However, its therapeutic effect is sparsely interpreted in the language of modern physiology. To objectively evaluate its therapeutic effect, we focused on dry cupping treatment and utilized near-infrared spectroscopy (NIRS) to assess the concentration change in oxy-hemoglobin ([HbO 2 ]), deoxy-hemoglobin ([Hb]), and blood volume in the course of cupping therapy over 13 volunteers on the infraspinatus muscle, where is usually applied for shoulder pains. Both a prominent drop in [Hb] and a significant elevation in [HbO 2 ] in the tissue surrounding the cupping site were observed during both cupping and post-treatment, manifesting the enhancement of oxygen uptake. This resulting promotion indicates potential positive therapeutic effect of cupping therapy in hemodynamics for facilitating muscular functions.

Aphasia therapy in the age of globalization: cross-linguistic therapy effects in bilingual aphasia.

Ansaldo, Ana Inés; Saidi, Ladan Ghazi

2014-01-01

Globalization imposes challenges to the field of behavioural neurology, among which is an increase in the prevalence of bilingual aphasia. Thus, aphasiologists have increasingly focused on bilingual aphasia therapy and, more recently, on the identification of the most efficient procedures for triggering language recovery in bilinguals with aphasia. Therapy in both languages is often not available, and, thus, researchers have focused on the transfer of therapy effects from the treated language to the untreated one. This paper discusses the literature on bilingual aphasia therapy, with a focus on cross-linguistic therapy effects from the language in which therapy is provided to the untreated language. Fifteen articles including two systematic reviews, providing details on pre- and posttherapy in the adult bilingual population with poststroke aphasia and anomia are discussed with regard to variables that can influence the presence or absence of cross-linguistic transfer of therapy effects. . The potential for CLT of therapy effects from the treated to the untreated language depends on the word type, the degree of structural overlap between languages, the type of therapy approach, the pre- and postmorbid language proficiency profiles, and the status of the cognitive control circuit.

2008-01-01

Clinical variables that affect treatment outcome for marijuana dependent individuals are not yet well understood, including the effects of cognitive functioning. To address this, level of cognitive functioning and treatment outcome were investigated. Twenty marijuana-dependent outpatients were administered a neuropsychological battery at treatment entry. All patients received 12 weekly individual sessions of combined motivational enhancement therapy and cognitive behavioral therapy. The Wilcoxon Exact Test was used to compare cognitive functioning test scores between completers and dropouts, and the Fisher Exact Test was used to compare proportion of negative urines between those with higher and lower scores on the cognitive tests. Marijuana abstinence was unrelated to cognitive functioning. However, dropouts scored significantly lower than completers on measures of abstract reasoning and processing accuracy, providing initial evidence that cognitive functioning plays a role in treatment retention of adult marijuana dependent patients. If supported by further studies, the findings may help inform the development of interventions tailored for cognitively impaired marijuana dependent patients. PMID:18329188

Hodge, David R; Lietz, Cynthia A

2014-11-01

Cognitive-behavioral therapy (CBT) that has been modified to incorporate clients' spiritual beliefs and practices has been used to treat a variety of problems. This study examines the utility of this modality with the treatment of alcohol dependence and other forms of substance abuse. Toward this end, six focus groups (three therapist groups and three client groups) were conducted to identify the presumed benefits and limitations of using spiritually modified CBT in substance dependence treatment. In terms of benefits, spiritually modified CBT was perceived to enhance outcomes through operationalizing horizontal and vertical sources of social support, divine coping resources, and spiritual motivation. Potential challenges include the risk of therapists inadvertently imposing their own beliefs during the modification process and the possibility of offending clients when conflicts in belief systems emerge, particularly in group setting. The article concludes by providing suggestions for incorporating spiritually modified CBT into treatment and develops a number of illustrative examples of spiritually modified CBT self-statements.

The topic of the present paper concerns the human joint cartilage therapy performed by the magnetic induction field. There is proved the thesis that the applied magnetic field for concrete cartilage illness should depend on the proper relative and concrete values of applied magnetic induction, intensity as well the time of treatment duration. Additionally, very important are frequencies and amplitudes of magnetic field as well as magnetic permeability of the synovial fluid. The research methods used in this paper include: magnetic induction field produced by a new Polish and German magneto electronic devices for the therapy of human joint cartilage diseases, stationary and movable magnetic applicators, magnetic bandage, ferrofluid injections, author's experience gained in Germany research institutes and practical results after measurements and information from patients. The results of this paper concern concrete parameters of time dependent electro-magnetic field administration during the joint cartilage therapy duration and additionally concern the corollaries which are implied from reading values gained on the magnetic induction devices. The main conclusions obtained in this paper are as follows: Time dependent magnetic induction field increases the dynamic viscosity of movable synovial fluid and decreases symptoms of cartilage illness for concrete intensity of magnetic field and concrete field line architecture. The ferrofluid therapy and phospholipids bilayer simultaneously with the administrated external electromagnetic field, increases the dynamic viscosity of movable synovial fluid.

Sleep health and its assessment and management in physical therapy practice: the evidence.

Coren, Stanley

2009-07-01

Sleep and sleep deprivation have become major health issues in our modern society. Impaired sleep can negatively affect physical and psychological well-being, and conversely, certain common conditions can impair sleep. Furthermore, insufficient or disrupted sleep can contribute to functional impairments. As health care professionals, physical therapists are singularly concerned with function and well-being. To understand the role of sleep and sleep deprivation on health, this article describes sleep, our contemporary culture of sleeplessness, insomnia, sleep needs, the physical cost of inadequate sleep, the psychological cost of sleep deprivation, and the effects of sleep debt on safety. How to assess an individual's sleep debt is then described, and a sleep inventory questionnaire and scoring scale are presented. Evidence-based recommendations for optimizing sleep are outlined, and these can be readily implemented by the busy clinician. The sleep inventory questionnaire can be used to evaluate the outcome of these recommendations or other interventions as well as serve as an assessment tool. Based on the literature, the assessment and evaluation of sleep and basic sleep recommendations need to be considered as fundamental clinical competencies in contemporary physical therapy care.

Our aim was to evaluate the validity of the cervical vertebra maturation (CVM) method as an indicator of skeletal age during the circumpubertal period by correlating the CVM method with the hand-wrist maturation (HWM) method in an attempt to eliminate the need for hand-wrist radiographs for maturity assessment. Hand-wrist and lateral cephalometric radiographs of 400 Chinese were randomly selected. The age for girls was between 10 years and 15 years and for boys it was between 12 years and 17 years, so that they were within the circumpubertal period. The CVM was assessed by a method developed by Baccetti and co-workers, whereas hand-wrist maturation was assessed by Fishman's method. The CVM was significantly correlated with HWM skeletal age. (Spearman's r boys 0.9206, girls = 0.9363). All the patients in cervical vertebra stage 3 (CVS3) of CVM corresponded to skeletal maturation indicator 2 (SMI2) or SMI3 stages of HWM (around the peak of the growth spurt). The method error was insignificant. CVM is a valid indicator of skeletal growth during the circumpubertal period. This work will provide dental practitioners with information on jaw growth modification therapy. (orig.)

2007-01-01

Stroke is a devastating disease and a leading cause of death and disability. Currently, the only FDA approved therapy for acute ischemic stroke is the intravenous administration of the thrombolytic medication, recombinant tissue plasminogen activator (tPA). However, this treatment has many contraindications and can have dangerous side effects such as intra-cerebral hemorrhage. These treatment limitations have led to much interest in potential adjunctive therapies, such as therapeutic hypothermia (T ≤ 35 deg. C) and ultrasound enhanced thrombolysis. Such interest may lead to combining these therapies with tPA to treat stroke, however little is known about the effects of temperature on the thrombolytic efficacy of tPA. In this work, we measure the temperature dependence of the fractional clot mass loss Δm(T) resulting from tPA exposure in an in vitro human clot model. We find that the temperature dependence is well described by an Arrhenius temperature dependence with an effective activation energy E eff of 42.0 ± 0.9 kJ mole -1 . E eff approximates the activation energy of the plasminogen-to-plasmin reaction of 48.9 kJ mole -1 . A model to explain this temperature dependence is proposed. These results will be useful in predicting the effects of temperature in future lytic therapies

Lambrinos, Anna; Chan, Brian; Wells, David; Holubowich, Corinne

2017-01-01

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

Individuals with a history of heroin dependence are overrepresented in American correctional facilities and 75% of inmates with a drug use disorder do not receive treatment during incarceration or after release. Medication-assisted treatment (MAT) with opiate agonists, such as methadone or buprenorphine, constitute standard of care; to guide planning for an expansion of drug treatment services in correctional facilities, a needs assessment was conducted at the Department of Correction and Rehabilitation (DCR) of Puerto Rico (PR). We report on the research process, the findings that informed our recommendations for the PCR to expand MAT for eligible inmates, and lessons learned. PMID:22263714

Introduction: Pulmonary oligometastases have conventionally been managed with surgery and/or systemic therapy. However, given concerns about the high cost of systemic therapy and improvements in local treatment of metastatic cancer, the optimal cost-effective management of these patients is unclear. Therefore, we sought to assess the cost-effectiveness of initial management strategies for pulmonary oligometastases. Methods and Materials: A cost-effectiveness analysis using a Markov modeling approach was used to compare average cumulative costs, quality adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) among 3 initial disease management strategies: video-assisted thoracic surgery (VATS) wedge resection, stereotactic body radiation therapy (SBRT), and systemic therapy among 5 different cohorts of patient disease: (1) melanoma; (2) non-small cell lung cancer adenocarcinoma without an EGFR mutation (NSCLC AC); (3) NSCLC with an EGFR mutation (NSCLC EGFRm AC); (4) NSCLC squamous cell carcinoma (NSCLC SCC); and (5) colon cancer. One-way sensitivity analyses and probabilistic sensitivity analyses were performed to analyze uncertainty with regard to model parameters. Results: In the base case, SBRT was cost effective for melanoma, with costs/net QALYs of $467,787/0.85. In patients with NSCLC, the most cost-effective strategies were SBRT for AC ($156,725/0.80), paclitaxel/carboplatin for SCC ($123,799/0.48), and erlotinib for EGFRm AC ($147,091/1.90). Stereotactic body radiation therapy was marginally cost-effective for EGFRm AC compared to erlotinib with an incremental cost-effectiveness ratio of $126,303/QALY. For colon cancer, VATS wedge resection ($147,730/2.14) was the most cost-effective strategy. Variables with the greatest influence in the model were erlotinib-associated progression-free survival (EGFRm AC), toxicity (EGFRm AC), cost of SBRT (NSCLC SCC), and patient utilities (all histologies). Conclusions: Video-assisted thoracic

Objective. The diagnostic significance of an enlarged pituitary gland regarding both shape and size parameters on MR imaging has previously been demonstrated in children with central precocious puberty. This study was designed to assess changes in these parameters following successful suppressive therapy of central precocious puberty with the gonadotropin-releasing hormone (GnRH) analogue. Materials and methods. Twelve girls (mean age 7.3 years) with central precocious puberty were prospectively enrolled in our study protocol. Sagittal and coronal MR images of the pituitary region were obtained in all patients before treatment and after at least 6 months of GnRH analogue therapy (mean 18.0 months). Parameters measured included pituitary gland height, length, width, sagittal cross-sectional area, and volume. Results. All patients had excellent clinical response to treatment with arrest of secondary sexual development, normalization of serum estradiol levels, and complete obliteration of the LH response to diagnostic GnRH stimulation. No significant change occurred in any pituitary size or shape parameter following GnRH analogue therapy. Conclusion. Favorable clinical response to GnRH analogue therapy in central precocious puberty is not accompanied by significant a change in pituitary gland size and shape. (orig.)

Hospice music therapy is delivered in both homes and nursing homes (NH). No studies to date have explored differences in music therapy delivery between home and NH hospice patients. To compare music therapy referral reasons and delivery for hospice patients living in NH versus home. A retrospective, electronic medical record review was conducted from a large U.S. hospice of patients receiving music therapy between January 1, 2006, and December 31, 2010. Among the 4,804 patients, 2,930 lived in an NH and 1,847 patients lived at home. Compared to home, NH hospice patients were more likely to be female, older, unmarried, and Caucasian. For home hospice patients, the top referral reasons were patient/family emotional and spiritual support, quality of life, and isolation. The most frequent referral reasons for NH hospice patients were isolation, quality of life, and patient/family emotional and spiritual support. Differences in music therapy delivery depended mainly on patients' primary diagnosis and location of care. Results suggest differences in referral reasons and delivery based on an interaction between location of care and patient characteristics. Delivery differences are likely a result of individualized assessment and care plans developed by the music therapist and other interdisciplinary team members to address the unique needs of the patient. Thus, it is important to have professionally trained music therapists assess and provide tailored music-based interventions for patients with different referral reasons and personal characteristics. This study also supports staffing decisions based on patient need rather than average daily census. © the American Music Therapy Association 2015. All rights reserved.

Full Text Available Context The use of fecal markers to monitor Crohn's disease is crucial for assessing the response to treatment. Objective To assess the inflammatory activity of Crohn's disease by comparing fecal markers (calprotectin and lactoferrin, colonoscopy combined with biopsy, and the Crohn's disease activity index (CDAI, as well as serum markers, before treatment with infliximab, after the end of induction, and after the end of maintenance. Methods Seventeen patients were included who had been previously diagnosed with Crohn's disease and were using conventional treatment but required the introduction of biological therapy with infliximab. Each patient underwent a colonoscopy with biopsy, serum, and fecal (calprotectin and lactoferrin tests to assess inflammatory activity, and CDAI assessments before treatment with infliximab, after induction (week 8, and after maintenance (week 32. Results The calprotectin levels exhibited significant reductions (P = 0.04 between the assessment before treatment with infliximab and the end of induction, which did not occur after the end of the maintenance phase. Lactoferrin remained positive throughout the three phases of the study. Regarding the histological assessment, a significant difference was found only between the assessment before treatment and after the end of maintenance (P = 0.036, and 60% of the patients exhibited histological improvements after the completion of the follow-up period. The CDAI exhibited a significant difference between the assessment before treatment with infliximab and after induction, as well as before treatment and after maintenance (P<0.01. Conclusion Calprotectin and lactoferrin are not useful for monitoring inflammatory activity in Crohn's disease patients who are subjected to biological therapy.

To assess the efficacy and safety of сortexin in the treatment of children with cerebral palsy (CP) combined with epilepsy. Eighty-four patients (55 boys and 29 girls), aged from 1 to 11 years, with CP combined with epilepsy received cortexin together with antiepileptic drugs (AEDs). Cortexin was administered in doses of 5-10 mg depending on the patient's age and body weight intramuscularly during hospitalization. Cortexin as add-on to AEDs reduced for more than two times the number of seizures, along with improvement of motor function, in 31 (36.9%) patients. The improvement of motor function, but without a significant decrease in epileptic seizures, was achieved in 15 (17.8%) of the patients. Reduction of epileptic seizures frequency (>2 times), but without a significant effect on motor function, was observed in 14 cases (16.7%). Twenty-three patients (27.4%) did not respond the therapy. The aggravation of epileptic seizures during cortexin therapy was observed in only 1 girl with West syndrome (1.2%), and this was significantly lower than the probability of seizures aggravation on AED. Polypeptide nootropic medication cortexin demonstrated efficacy and safety as adjunctive therapy in children with CP combined with epilepsy.

Cognitive remediation therapy (CRT) is a specialized treatment approach targeting cognitive weaknesses in anorexia nervosa (AN). Regarding follow-up effects of CRT, there are only few studies available; for adolescents, there are no data. Forty-eight adolescents with AN were assigned to receive either CRT and treatment as usual (TAU) or TAU alone. Assessments were performed at baseline (n = 48) and compared with assessments at a 6-month follow-up (n = 33). Outcome measures were set-shifting, central coherence, eating disorder and general psychopathology. The completion rate was higher in CRT compared with TAU. There were no significant differences in neuropsychological and clinical variables. Changes in body mass index percentile showed a trend towards significance for CRT. Dropout analyses revealed no significant predictors. Results provide a first insight into follow-up-assessments of CRT in adolescent AN. More randomized controlled studies are needed to clarify the long-term effects of CRT. Copyright © 2017 John Wiley & Sons, Ltd and Eating Disorders Association.

2014-01-01

While conservative management such as fluid, bowel rest, and antibiotics is the mainstay of current acute pancreatitis management, there is a lot of promise in pharmacologic therapies that target various aspects of the pathogenesis of pancreatitis. Extensive review of preclinical studies, which include assessment of therapies such as anti-secretory agents, protease inhibitors, anti-inflammatory agents, and anti-oxidants are discussed. Many of these studies have shown therapeutic benefit and improved survival in experimental models. Based on available preclinical studies, we discuss potential novel targeted pharmacologic approaches that may offer promise in the treatment of acute pancreatitis. To date a variety of clinical studies have assessed the translational potential of animal model effective experimental therapies and have shown either failure or mixed results in human studies. Despite these discouraging clinical studies, there is a great clinical need and there exist several preclinical effective therapies that await investigation in patients. Better understanding of acute pancreatitis pathophysiology and lessons learned from past clinical studies are likely to offer a great foundation upon which to expand future therapies in acute pancreatitis.

Addressing record high rates of Chlamydia trachomatis incidence in the United States requires the utilization of effective strategies, such as expedited partner therapy, to reduce reinfection and further transmission. Expedited partner therapy, which can be given as a prescription or medication, is a strategy to treat the sexual partners of index patients diagnosed with a sexually transmitted infection without prior medical evaluation of the partners. There are multiple steps in the prescription-expedited partner therapy cascade, and we sought to identify pharmacy-level barriers to implementing prescription-expedited partner therapy for Chlamydia trachomatis treatment. We used spatial analysis and ArcGIS, a geographic information system, to map and assess geospatial access to pharmacies within Baltimore, MD, neighborhoods with the highest rates of Chlamydia trachomatis (1180.25-4255.31 per 100,000 persons). Expedited partner therapy knowledge and practices were collected via a telephone survey of pharmacists employed at retail pharmacies located in these same neighborhoods. Cost of antibiotic medication in US dollars was collected. Census tracts with the highest Chlamydia trachomatis incidence rates had lower median pharmacy density than other census tracts (26.9 per 100,000 vs 31.4 per 100,000, P barriers to implementing prescription-expedited partner therapy. Although most Baltimore pharmacists were unaware of expedited partner therapy, they were generally receptive to learning about and filling expedited partner therapy prescriptions. This finding suggests the need for wide dissemination of educational material targeted to pharmacists. In areas with limited geographic access to pharmacies, expedited partner therapy strategies that do not depend on partners physically accessing a pharmacy merit consideration.

Safe drinking water is a global challenge for rural populations dependent on unregulated water. A scoping review of research on human health risk assessments (HHRA) applied to this vulnerable population may be used to improve assessments applied by government and researchers. This review aims to summarize and describe the characteristics of HHRA methods, publications, and current literature gaps of HHRA studies on rural populations dependent on unregulated or unspecified drinking water. Peer-reviewed literature was systematically searched (January 2000 to May 2014) and identified at least one drinking water source as unregulated (21%) or unspecified (79%) in 100 studies. Only 7% of reviewed studies identified a rural community dependent on unregulated drinking water. Source water and hazards most frequently cited included groundwater (67%) and chemical water hazards (82%). Most HHRAs (86%) applied deterministic methods with 14% reporting probabilistic and stochastic methods. Publications increased over time with 57% set in Asia, and 47% of studies identified at least one literature gap in the areas of research, risk management, and community exposure. HHRAs applied to rural populations dependent on unregulated water are poorly represented in the literature even though almost half of the global population is rural.

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

Objectives: In this review, we discuss the treatment of refractory overactive bladder (OAB) that has not adequately responded to medication therapy and we propose an appropriate care pathway to the treatment of OAB. We also attempt to address the cost of OAB treatments. Materials and Methods: A selective expert review of the current literature on the subject of refractory OAB using MEDLINE was performed and the data is summarized. We also review our experience in treating refractory OAB. The role and outcomes of various treatment options for refractory OAB are discussed and combined therapy with oral anticholinergics is explored. Emerging remedies including intravesical botulinum toxin injection and pudendal neuromodulation are also reviewed, along with conventional surgical options. Results: In general behavioral therapy, pelvic floor electrical stimulation, magnetic therapy and posterior tibial nerve stimulation (PTNS), have shown symptom decreases in 50-80% of patients with OAB. Depending on the study, combination therapy with oral anticholinergics seems to improve efficacy of behavioral therapy and PTNS in approximately 10-30%. In multicenter, long-term randomized controlled trials, sacral neuromodulation has been shown to improve symptoms of OAB and OAB incontinence in up to 80% of the patients treated. Studies involving emerging therapies such as pudendal serve stimulation suggest that there may be a 15-20% increase in efficacy over sacral neuromodulation, but long-term studies are not yet available. Another emerging therapy, botulinum toxin, is also showing similar success in reducing OAB symptoms in 80-90% of patients. Surgical approaches, such as bladder augmentation, are a last resort in the treatment of OAB and are rarely used at this point unless upper tract damage is a concern and all other treatment options have been exhausted. Conclusion: The vast majority of OAB patients can be managed successfully by behavioral options with or without

Purpose: The goal of this study was to evaluate coregistered [ 18 F] fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) for the detection of persistent disease after definitive radiation therapy in head and neck cancer. Methods and Materials: Posttreatment FDG-PET/CT was performed in 28 patients on average 8 weeks (range, 4 to 15.7 weeks) after completing definitive radiation therapy. FDG-PET/CT was visually analyzed for the entire patient group and at two time points (4-8 and >8 weeks) after treatment. The contrast-enhanced CT portion of PET/CT was separately analyzed blinded to the results of coregistered FDG-PET/CT and classified as negative or positive for residual locoregional disease. Pathologic findings and clinical follow-up served as the reference standard. Results: Follow-up data were available for all 28 patients (median, 17.6 months). Regarding the detection of residual disease, the overall sensitivity and specificity of FDG-PET/CT was 76.9% and 93.3%, respectively, compared with 92.3% and 46.7% for contrast-enhanced CT. The accuracy of FDG-PET/CT was 85.7%, compared with 67.9% for CT alone. All false-negative (n = 3) and false-positive (n = 1) FDG-PET/CT results occurred between 4 and 8 weeks after treatment. At 8 weeks or later after treatment, the specificity of CT was 28%, compared with 100% for FDG-PET/CT. Conclusions: The metabolic-anatomic information from coregistered FDG-PET/CT provided the most accurate assessment for treatment response when performed later than 8 weeks after the conclusion of radiation therapy. FDG-PET/CT excelled by a higher specificity and overall diagnostic performance than CT imaging alone. These results support a potential clinical role of FDG-PET/CT in the early assessment of therapy response after definitive radiation therapy

On September 25th, 1987 methadone was legalized in Austria for therapeutic use in drug addiction treatment in case of: 1. Long-term drug addiction with intravenous application of the drug, and several unsuccessful withdrawal therapies and/or 2. opiate addiction through intravenous application of the drug along with an existing HIV-1 infection. Since than, 291 patients were treated with methadone at the drug-dependency outpatient clinic of the Psychiatric Clinic of the University of Vienna. In 1990, 96 patients treated for more than one year were investigated using a standardized questionnaire. The image in which crime, prostitution, poverty, ill health all merge was broken by this decriminalization. Methadone treatment offers a first step toward social rehabilitation for drug addicts who have been living as criminals on the fringe of society.

Dysphagia after stroke is associated with increased mortality, higher dependence, and longer hospitalization. Different therapeutic strategies have been introduced to improve swallowing impairment. There are no current studies that compare rehabilitation swallowing therapy (RST) and neuromuscular electrical stimulation therapy (NMES). To compare treatment outcomes between RST and NMES intervention in stroke patients with pharyngeal dysphagia. A randomized controlled study. Twenty-three stroke patients with persistent pharyngeal dysphagia (RST 11, NMES 12) were enrolled in the present study. The subjects received 60 minutes of either RST or NMES treatment for five consecutive days, had two days off and then five more consecutive days of treatment for a four-week period or until they reached functional oral intake scale (FOIS) level 7. The outcome measures assessed were change in FOIS, complications related to the treatment and number of therapy sessions. There were no significant differences in the stroke characteristics and the VFSS results between the two groups. At the end of treatment, the average numbers of therapy sessions per subject in the RST and NMES groups were 18.36 +/- 3.23 and 17.25 +/- 5.64, respectively, a non-significant difference. Average changes in FOIS scores were 2.46 +/- 1.04 for the RST group and 3.17 +/- 1.27 for the NMES group, statistically significant at p stroke patients, NMES was significantly superior.

Inter-dependence not Over-dependence: Reducing Urban Transport Energy Dependence

Energy Technology Data Exchange (ETDEWEB)

Saunders, Michael James; Rodrigues da Silva, Antonio Nelson

2007-07-01

A major issue of concern in today's world is urban transport energy dependence and energy supply security. In an energy inter-dependent world, energy over-dependence brings risks to urban transport systems. Many urban areas are over-dependent on finite petroleum resources for transport. New technology and the development and integration of renewable resources into transport energy systems may reduce some of the current transport energy dependence of urban areas. However, the most effective means of reducing energy dependence is to first design urban areas for this condition. An urban policy framework is proposed that requires transport energy dependence to be measured and controlled in the urban development process. A new tool has been created for this purpose, the Transport Energy Specification (TES), which measures transport energy dependence of urban areas. This creates the possibility for cities to regulate urban development with respect to energy dependence. Trial assessments were performed in Germany, New Zealand and Brazil; initial analysis by transport and government professionals shows promise of this tool being included into urban policy.

Induction immunosuppressive therapies for patients undergoing renal transplantation are reviewed. The goal of induction therapy is to prevent acute rejection during the early posttransplantation period by providing a high degree of immunosuppression at the time of transplantation. Induction therapy is often considered essential to optimize outcomes, particularly in patients at high risk for poor short-term outcomes. All of the induction immunosuppressive agents currently used are biological agents and are either monoclonal (muromonab-CD3, daclizumab, basiliximab, alemtuzumab) or polyclonal (antithymocyte globulin [equine] or antithymocyte globulin [rabbit]) antibodies. Although antithymocyte globulin (rabbit) is not labeled for induction therapy, it is used for this purpose more than any other agent. Basiliximab is not considered as potent an immunosuppressive agent but has a much more favorable adverse-effect profile compared with antithymocyte globulin (rabbit) and is most commonly used in patients at low risk for acute rejection. Rituximab is being studied for use as induction therapy but to date has not demonstrated any significant benefits over placebo. While head-to-head data are available comparing most induction agents, the final decision on the most appropriate induction therapy for a transplant recipient is highly dependent on preexisting medical conditions, donor characteristics, and the maintenance immunosuppressive regimen to be used. No standard induction immunosuppressive regimen exists for patients undergoing renal transplantation. Antithymocyte globulin (rabbit) is the most commonly used agent, whereas basiliximab appears safer. The choice of regimen depends on the preferences of clinicians and institutions.

Full Text Available Introduction. The sources of Reactive Oxidative Species (ROS in the organism are the respiratory processes occurring in cells catalyzed by different enzymes. Operation of ROS is balanced by antioxidants, the compounds; although present in low concentrations, they significantly inhibit the degree of oxidation of particular molecules. The Aim of the Study. The aim of this study was to assess the changes in the integrated antioxidant system under the influence of radon therapy in osteoarthritis patients. Material and Methods. Observation included 35 patients suffering from degenerative joints and disc disease (mean age 56.5 years undergoing radon water therapy and control group that consisted of 15 osteoarthritis patients (mean age 54.2 without contact with radon water. Before therapy and after 18 days of treatment, serum total antioxidant status (TAS was assessed with the use of standard colorimetric assay. Results. In the study group, we observed trends to increase TAS concentration, whereas, in the control group, TAS concentration was decreasing. Conclusions. (1 Radon waters treatment influenced the level of TAS of osteoarthritis patients treated with the radon water. (2 The change in TAS concentrations in the study group may be the result of low doses of ionizing radiation, but further studies on larger patient’s groups are demanded. This study is registered with number NCT03274128.

The assessment of knowledge and learning in competence spaces: The gain-loss model for dependent skills.

Science.gov (United States)

Anselmi, Pasquale; Stefanutti, Luca; de Chiusole, Debora; Robusto, Egidio

2017-11-01

The gain-loss model (GaLoM) is a formal model for assessing knowledge and learning. In its original formulation, the GaLoM assumes independence among the skills. Such an assumption is not reasonable in several domains, in which some preliminary knowledge is the foundation for other knowledge. This paper presents an extension of the GaLoM to the case in which the skills are not independent, and the dependence relation among them is described by a well-graded competence space. The probability of mastering skill s at the pretest is conditional on the presence of all skills on which s depends. The probabilities of gaining or losing skill s when moving from pretest to posttest are conditional on the mastery of s at the pretest, and on the presence at the posttest of all skills on which s depends. Two formulations of the model are presented, in which the learning path is allowed to change from pretest to posttest or not. A simulation study shows that models based on the true competence space obtain a better fit than models based on false competence spaces, and are also characterized by a higher assessment accuracy. An empirical application shows that models based on pedagogically sound assumptions about the dependencies among the skills obtain a better fit than models assuming independence among the skills. © 2017 The British Psychological Society.

Full Text Available Background: Predictors of relapse to methamphetamine use are poorly understood. State variables may play an important role in relapse, but they have been difficult to measure at frequent intervals in outpatients.Methods: We conducted a feasibility study of the use of cellular telephones to collect state variable data from outpatients. Six subjects in treatment for methamphetamine dependence were called three times per weekday for approximately seven weeks. Seven questionnaires were administered that assessed craving, stress, affect and current type of location and social environment.Results: 395/606 (65% of calls attempted were completed. The mean time to complete each call was 4.9 (s.d. 1.8 minutes and the mean time to complete each item was 8.4 (s.d. 4.8 seconds. Subjects rated the acceptability of the procedures as good. All six cellular phones and battery chargers were returned undamaged.Conclusion: Cellular telephones are a feasible method for collecting state data from methamphetamine dependent outpatients.

The effect of rehabilitative training after stroke is dose-dependent. Out-patient rehabilitation training is often limited by transport logistics, financial resources and a lack of motivation/compliance. We studied the feasibility of an unsupervised arm therapy for self-directed rehabilitation therapy in patients' homes. An open-label, single group study involving eleven patients with hemiparesis due to stroke (27 ± 31.5 months post-stroke) was conducted. The patients trained with an inertial measurement unit (IMU)-based virtual reality system (ArmeoSenso) in their homes for six weeks. The self-selected dose of training with ArmeoSenso was the principal outcome measure whereas the Fugl-Meyer Assessment of the upper extremity (FMA-UE), the Wolf Motor Function Test (WMFT) and IMU-derived kinematic metrics were used to assess arm function, training intensity and trunk movement. Repeated measures one-way ANOVAs were used to assess differences in training duration and clinical scores over time. All subjects were able to use the system independently in their homes and no safety issues were reported. Patients trained on 26.5 ± 11.5 days out of 42 days for a duration of 137 ± 120 min per week. The weekly training duration did not change over the course of six weeks (p = 0.146). The arm function of these patients improved significantly by 4.1 points (p = 0.003) in the FMA-UE. Changes in the WMFT were not significant (p = 0.552). ArmeoSenso based metrics showed an improvement in arm function, a high number of reaching movements (387 per session), and minimal compensatory movements of the trunk while training. Self-directed home therapy with an IMU-based home therapy system is safe and can provide a high dose of rehabilitative therapy. The assessments integrated into the system allow daily therapy monitoring, difficulty adaptation and detection of maladaptive motor patterns such as trunk movements during reaching.

Smith, Warren D; Bagley, Anita

2010-01-01

Children with cerebral palsy may have difficulty walking and may fall frequently, resulting in a decrease in their participation in school and community activities. It is desirable to assess the effectiveness of mobility therapies for these children on their functioning during everyday living. Over 50 hours of tri-axial accelerometer and digital video recordings from 35 children with cerebral palsy and 51 typically-developing children were analyzed to develop algorithms for automatic real-time processing of the accelerometer signals to monitor a child's level of activity and to detect falls. The present fall-detection algorithm has 100% specificity and a sensitivity of 100% for falls involving trunk rotation. Sensitivities for drops to the knees and to the bottom are 72% and 78%, respectively. The activity and fall-detection algorithms were implemented in a miniature, battery-powered microcontroller-based activity/fall monitor that the child wears in a small fanny pack during everyday living. The monitor continuously logs 1-min. activity levels and the occurrence and characteristics of each fall for two-week recording sessions. Pre-therapy and post-therapy recordings from these monitors will be used to assess the efficacies of alternative treatments for gait abnormalities.

This study investigated whether diffuse optical spectroscopy (DOS) measurements could assess clinical response to photodynamic therapy (PDT) in patients with head and neck squamous cell carcinoma (HNSCC). In addition, the correlation between parameters measured with DOS and the crosslinking of signal transducer and activator of transcription 3 (STAT3), a molecular marker for PDT-induced photoreaction, was investigated. Thirteen patients with early stage HNSCC received the photosensitizer 2-[1-hexyloxyethyl]-2-devinylpyropheophorbide-a (HPPH) and DOS measurements were performed before and after PDT in the operating room (OR). In addition, biopsies were acquired after PDT to assess the STAT3 crosslinking. Parameters measured with DOS, including blood volume fraction, blood oxygen saturation (StO2), HPPH concentration (cHPPH), HPPH fluorescence, and blood flow index (BFI), were compared to the pathologic response and the STAT3 crosslinking. The best individual predictor of pathological response was a change in cHPPH (sensitivity=60%, specificity=100%), while discrimination analysis using a two-parameter classifier (change in cHPPH and change in StO2) classified pathological response with 100% sensitivity and 100% specificity. BFI showed the best correlation with the crosslinking of STAT3. These results indicate that DOS-derived parameters can assess the clinical response in the OR, allowing for earlier reintervention if needed.

Music therapy is a predominantly non-verbal psychotherapy based on music improvisation, embedded in a therapeutic relationship. This is the reason why music therapy is also used to treat depression. To examine the efficacy of music therapy and to report on the results of recent research into the value of music therapy as a treatment for depression. We reviewed the literature on recent research into music therapy and depression, reporting on the methods used and the results achieved, and we assessed the current position of music therapy for depression in the context of evidence-based scientific research. A wide variety of research methods was used to investigate the effects of using music therapy as a psychotherapy. Most studies focused usually on the added value that music therapy brings to the standard form of psychiatric treatment, when administered with or without psychopharmacological support. Music therapy produced particularly significant and favourable results when used to treat patients with depression. Current research into music therapy and depression points to a significant and persistent reduction in patients' symptoms and to improvements in their quality of life. However, further research is needed with regard to the best methods of illustrating the effects of music therapy.

Based on preclinical studies showing that the partial N-methyl-D-aspartate (NMDA) agonist D-cycloserine (DCS) facilitates extinction of cocaine self-administration and cocaine-induced conditioned place preference, we evaluated whether 50 mg of DCS would reduce craving to cocaine cues when combined with cue exposure (CE) in cocaine dependent humans. In this double-blind placebo-controlled pilot study, 47 cocaine dependent participants were randomized to DCS or placebo (PBO), plus CE. Participants received DCS or PBO 30 minutes prior to two CE sessions, conducted one day apart. Craving and heart rate was assessed prior to CE sessions, during CE trials, and after CE trials. These measures were assessed again at a 1-week follow-up (session 3) after the second CE session. DCS failed to significantly attenuate cocaine cue reactivity based on subjective craving and physiological reactivity (heart rate) compared to PBO. The CE protocol, consisting of repeated exposure to drug cues combined with skills training, resulted in extinction to cocaine cues as suggested by decreased craving within and between sessions in both treatment conditions. All participants exhibited elevated heart rate with repeated exposures, demonstrating a potentiation in heart rate between sessions. 50 mg of DCS may not be effective for extinguishing reactivity to drug cues for individuals with cocaine dependence. Future studies examining the effect of DCS on facilitating extinction to drug cues should examine variations in cue exposure length, number of CE presentations, and timing of DCS dose administration prior to cue exposures, which may differentially impact drug cue reactivity. © American Academy of Addiction Psychiatry.

1. To assess the efficacy of omalizumab therapy in improving sinonasal outcomes in refractory allergic fungal rhinosinusitis (AFRS) patients with moderate or severe asthma. 2. To determine if omalizumab therapy reduces the usage of corticosteroids or antifungal therapy in AFRS patients The clinical charts of patients with AFRS with moderate or severe asthma who received at least three subcutaneous injections of omalizumab therapy between 1st January 2012 and 1st May 2014 were retrospectively reviewed. These patients had undergone bilateral functional endoscopic sinus surgery (FESS) and failed adjunct medical treatments (oral or topical corticosteroids and/or antifungal therapy) prior to omalizumab therapy. Seven patients met the inclusion criteria and were included in this study. The mean age of the patients was 48.14. The average number of subcutaneous omalizumab injections was 7.57 (range 6-11) with a mean dosage of 287mg (range 225-375mg). The mean pre-omalizumab treatment Sino-Nasal Outcome Test-22 (SNOT-22) score was 52.14 while the mean post-omalizumab treatment SNOT-22 score was 35.86 (31% improvement). The mean pre-omalizumab therapy Phillpott-Javer endoscopic score (over the last one year before omalizumab therapy) was 36 while the mean post-omalizumab therapy endoscopic score (from the last clinic visit) was 14 (61% improvement). Omalizumab therapy reduced the dependence of AFRS patients on corticosteroid and antifungal treatments. Omalizumab therapy can be considered as a potential adjunct for the treatment for patients with refractory AFRS with moderate or severe asthma. However, larger prospective studies to confirm the findings of this study will be required. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.

A new perspective on human health risk assessment: Development of a time dependent methodology and the effect of varying exposure durations

International Nuclear Information System (INIS)

Siirila, Erica R.; Maxwell, Reed M.

2012-01-01

We present a new Time Dependent Risk Assessment (TDRA) that stochastically considers how joint uncertainty and inter-individual variability (JUV) associated with human health risk change as a function of time. In contrast to traditional, time independent assessments of risk, this new formulation relays information on when the risk occurs, how long the duration of risk is, and how risk changes with time. Because the true exposure duration (ED) is often uncertain in a risk assessment, we also investigate how varying the magnitude of fixed size durations (ranging between 5 and 70 years) of this parameter affects the distribution of risk in both the time independent and dependent methodologies. To illustrate this new formulation and to investigate these mechanisms for sensitivity, an example of arsenic contaminated groundwater is used in conjunction with two scenarios of different environmental concentration signals resulting from rate dependencies in geochemical reactions. Cancer risk is computed and compared using environmental concentration ensembles modeled with sorption as 1) a linear equilibrium assumption (LEA) and 2) first order kinetics (Kin). Results show that the information attained in the new time dependent methodology reveals how the uncertainty in other time-dependent processes in the risk assessment may influence the uncertainty in risk. We also show that individual susceptibility also affects how risk changes in time, information that would otherwise be lost in the traditional, time independent methodology. These results are especially pertinent for forecasting risk in time, and for risk managers who are assessing the uncertainty of risk. - Highlights: ► A human health, Time Dependent Risk Assessment (TDRA) methodology is presented. ► TDRA relays information on the magnitude, duration, and fluxes of risk in time. ► Kinetic and equilibrium concentration signals show sensitivity in TDRA results. ► In the TDRA results, individual susceptibility

Influence of radiation therapy on lung tissue in breast cancer patients. CT-assessed density changes 4 years after completion of radiotherapy

International Nuclear Information System (INIS)

Svane, G.; Rotstein, S.; Lax, I.

1995-01-01

CT-assessed density changes in lung tissues were measured in 22 disease-free breast cancer patients 4 years after completion of radiation therapy. All patients had previously undergone similar CT-examinations before treatment, 3 months, and 9 months after radiotherapy. In patients with visible areas of increased lung density at earlier CT-examinations a decrease of focal findings was observed at 4 years. In patients without focal findings, an increase in density relative to that before therapy was observed. The difference between the mean lung density values among those with visible radiological findings and those without was statistically significant both at 3 and 9 months after therapy. However, this difference did not persist at 4 years. These results may indicate a 2-phase development of radiation-induced lung damages - an acute phase and a late phase; the late phase emerging slowly, and in this study detectable 4 years after completion of radiation therapy.

Trials of anti-inflammatory therapies in non-relapsing progressive multiple sclerosis (MS) have been stubbornly negative except recently for an anti-CD20 therapy in primary progressive MS and a S1P modulator siponimod in secondary progressive MS. We argue that this might be because trials have been too short and have focused on assessing neuronal pathways, with insufficient reserve capacity, as the core component of the primary outcome. Delayed neuroaxonal degeneration primed by prior inflammation is not expected to respond to disease-modifying therapies targeting MS-specific mechanisms. However, anti-inflammatory therapies may modify these damaged pathways, but with a therapeutic lag that may take years to manifest. Based on these observations we propose that clinically apparent neurodegenerative components of progressive MS may occur in a length-dependent manner and asynchronously. If this hypothesis is confirmed it may have major implications for the future design of progressive MS trials. Copyright © 2016 Elsevier B.V. All rights reserved.

Asthma therapy in the United States in 1996

Directory of Open Access Journals (Sweden)

Gail G. Shapiro

1997-01-01

American physicians are trained to believe that the success of their treatment plan depends on communication with patients and families. They generally recognize the need to simplify the regimen, to provide written information reinforcing their instructions, to repeat these at each visit, and to observe the patient who uses metered dose inhalers. Many communities in the US have support groups for patients and families with asthma, which allow people to come together to share their concerns and frustrations. This seems to enhance compliance with medical therapy, as patients feel they are more involved in their disease than if they were passive recipients of information. Federal programs are ongoing to assess the outcome of these support interventions.

Radiosynoviorthesis as a therapy of osteoarthritis in dogs

International Nuclear Information System (INIS)

Franke, Christian; Meyer, C.

2010-01-01

In human medicine radiosynorviorthesis (RSO) is anestablished form of therapy in chronic inflammatory or active degenerative joint disease. Chronic lameness in dogs as a result of joint disease is a common problem. This study was carried out to establish the role of RSO in chronic inflammatory or active degenerative joint disease in dogs. In 33 dogs with 51 joints with ostearthritis RSO was performed. Before treatment a classification of 4 grades of lameness was determined in each dog. 4 weeks and 7 months later a new assessment considering this classification was performed to determine the change of lameness grade. Improvement of lameness was found in 43-75%. of joints, the improvement was dependent on grade of synovitic activity before therapy. There were no side effects observed. The dogs with distinct effusion and the dogs which responded well to intraarticulary steroid injection before-hand, showed the best results. In these dogs RSO lead to obvious prolonged lamefree intervalls and a marked reduction of pain medication and therefore to a better quality of life. (orig.)

data were available for other outcomes. Medium-term continuous data identified good effects for music therapy on negative symptoms using the Scale for the Assessment of Negative Symptoms (3 RCTs, n = 177, SMD - 0.55 95% CI -0.87 to -0.24, low-quality evidence). General mental state endpoint scores on the Positive and Negative Symptoms Scale were better for music therapy (2 RCTs, n = 159, SMD -0.97 95% CI -1.31 to -0.63, low-quality evidence), as were average endpoint scores on the Brief Psychiatric Rating Scale (1 RCT, n = 70, SMD -1.25 95% CI -1.77 to -0.73, moderate-quality evidence). Medium-term average endpoint scores using the Global Assessment of Functioning showed no effect for music therapy on general functioning (2 RCTs, n = 118, SMD -0.19 CI -0.56 to 0.18, moderate-quality evidence). However, positive effects for music therapy were found for both social functioning (Social Disability Screening Schedule scores; 2 RCTs, n = 160, SMD -0.72 95% CI -1.04 to -0.40), and quality of life (General Well-Being Schedule scores: 1 RCT, n = 72, SMD 1.82 95% CI 1.27 to 2.38, moderate-quality evidence). There were no data available for adverse effects, service use, engagement with services, or cost. Moderate- to low-quality evidence suggests that music therapy as an addition to standard care improves the global state, mental state (including negative and general symptoms), social functioning, and quality of life of people with schizophrenia or schizophrenia-like disorders. However, effects were inconsistent across studies and depended on the number of music therapy sessions as well as the quality of the music therapy provided. Further research should especially address the long-term effects of music therapy, dose-response relationships, as well as the relevance of outcome measures in relation to music therapy.

2005-11-01

Full Text Available Abstract Background Musculoskeletal physiotherapists routinely assess lumbar segmental motion during the clinical examination of a patient with low back pain. The validity of manual assessment of segmental motion has not, however, been adequately investigated. Methods In this prospective, multi-centre, pragmatic, diagnostic validity study, 138 consecutive patients with recurrent or chronic low back pain (R/CLBP were recruited. Physiotherapists with post-graduate training in manual therapy performed passive accessory intervertebral motion tests (PAIVMs and passive physiological intervertebral motion tests (PPIVMs. Consenting patients were referred for flexion-extension radiographs. Sagittal angular rotation and sagittal translation of each lumbar spinal motion segment was measured from these radiographs, and compared to a reference range derived from a study of 30 asymptomatic volunteers. Motion beyond two standard deviations from the reference mean was considered diagnostic of rotational lumbar segmental instability (LSI and translational LSI. Accuracy and validity of the clinical assessments were expressed using sensitivity, specificity, and likelihood ratio statistics with 95% confidence intervals (CI. Results Only translation LSI was found to be significantly associated with R/CLBP (p Conclusion This study provides the first evidence reporting the concurrent validity of manual tests for the detection of abnormal sagittal planar motion. PAIVMs and PPIVMs are highly specific, but not sensitive, for the detection of translation LSI. Likelihood ratios resulting from positive test results were only moderate. This research indicates that manual clinical examination procedures have moderate validity for detecting segmental motion abnormality.

Full Text Available Background. There is a need for tools to assess dependency among persons with severe impairments. Objectives. The aim was to compare the Functional Independence Measure (FIM and the Northwick Park Dependency Score (NPDS, in a sample from in-patient rehabilitation. Material and Methods. Data from 115 persons (20 to 65 years of age with neurological impairments was gathered. Analyses were made of sensitivity, specificity, positive predictive value, and negative predictive value. Agreement of the scales was assessed with kappa and concordance with Goodman-Kruskal’s gamma. Scale structures were explored using the Rank-Transformable Pattern of Agreement (RTPA. Content validation was performed. Results. The sensitivity of the NPDS as compared to FIM varied between 0.53 (feeding and 1.0 (mobility and specificity between 0.64 (mobility and 1.0 (bladder. The positive predictive value varied from 0.62 (mobility to 1.0 (bladder, and the negative predictive value varied from 0.48 (bowel to 1.0 (mobility. Agreement between the scales was moderate to good (four items and excellent (three items. Concordance was good, with a gamma of −.856, an asymptotic error (ase of .025, and P<.000. The parallel reliability between the FIM and the NPDS showed a tendency for NPDS to be more sensitive (having more categories when dependency is high. Conclusion. FIM and NPDS complement each other. NPDS can be used as a measure for severely injured patients who are sensitive when there is a high need of nursing time.

Nuclear reactions in the device and in the patient himself induce secondary radiations involving mainly neutrons which contribute to an additional dose for the patient. The author reports a study aimed at the assessment of these doses due to secondary neutrons in the case of ophthalmological and intra-cranial treatments. He presents a Monte Carlo simulation of the room and of the apparatus, reports the experimental validation of the model (dose deposited by protons in a water phantom, ambient dose equivalent due to neutrons in the treatment room, absorbed dose due to secondary particles in an anthropomorphic phantom), and the assessment with a mathematical phantom of doses dues to secondary neutrons received by organs during an ophthalmological treatment. He finally evokes current works of calculation of doses due to secondary neutrons in the case of intra-cranial treatments

WE-FG-BRB-00: The Challenges of Predicting RBE Effects in Particle Therapy and Opportunities for Improving Cancer Therapy

2016-06-15

The physical pattern of energy deposition and the enhanced relative biological effectiveness (RBE) of protons and carbon ions compared to photons offer unique and not fully understood or exploited opportunities to improve the efficacy of radiation therapy. Variations in RBE within a pristine or spread out Bragg peak and between particle types may be exploited to enhance cell killing in target regions without a corresponding increase in damage to normal tissue structures. In addition, the decreased sensitivity of hypoxic tumors to photon-based therapies may be partially overcome through the use of more densely ionizing radiations. These and other differences between particle and photon beams may be used to generate biologically optimized treatments that reduce normal tissue complications. In this symposium, speakers will examine the impact of the RBE of charged particles on measurable biological endpoints, treatment plan optimization, and the prediction or retrospective assessment of treatment outcomes. In particular, an AAPM task group was formed to critically examine the evidence for a spatially-variant RBE in proton therapy. Current knowledge of proton RBE variation with respect to dose, biological endpoint, and physics parameters will be reviewed. Further, the clinical relevance of these variations will be discussed. Recent work focused on improving simulations of radiation physics and biological response in proton and carbon ion therapy will also be presented. Finally, relevant biology research and areas of research needs will be highlighted, including the dependence of RBE on genetic factors including status of DNA repair pathways, the sensitivity of cancer stem-like cells to charged particles, the role of charged particles in hypoxic tumors, and the importance of fractionation effects. In addition to the physical advantages of protons and more massive ions over photons, the future application of biologically optimized treatment plans and their potential to

Although child neglect and substance abuse co-occur in greater than 60% of child protective service cases, intervention outcome studies are deplorably lacking. Therefore, a home-based Family Behavior Therapy is described in the treatment of a woman evidencing child neglect, substance dependence, domestic violence and other co-occurring problems. Treatment included contingency management, self control, stimulus control, communication and child management skills training exercises, and financial management components. Results indicated improvements in child abuse potential, home hazards, domestic violence, and drug use, which were substantiated by objective urinalysis testing, and tours of her home. Validity checks indicated the participant was being truthful in her responses to standardized questionnaires, and assessors were “blind” to study intent. Limitations (i.e., lack of experimental control and follow-up data collection) of this case example are discussed in light of these results. PMID:23226920

ABSTRACT Objective: To assess the distribution of stress produced on TMJ disc by chincup therapy, by means of the finite element method. Methods: a simplified three-dimensional TMJ disc model was developed by using Rhinoceros 3D software, and exported to ANSYS software. A 4.9N load was applied on the inferior surface of the model at inclinations of 30, 40, and 50 degrees to the mandibular plane (GoMe). ANSYS was used to analyze stress distribution on the TMJ disc for the different angulations, by means of finite element method. Results: The results showed that the tensile and compressive stresses concentrations were higher on the inferior surface of the model. More presence of tensile stress was found in the middle-anterior region of the model and its location was not altered in the three directions of load application. There was more presence of compressive stress in the middle and mid-posterior regions, but when a 50o inclined load was applied, concentration in the middle region was prevalent. Tensile and compressive stresses intensities progressively diminished as the load was more vertically applied. Conclusions: stress induced by the chincup therapy is mainly located on the inferior surface of the model. Loads at greater angles to the mandibular plane produced distribution of stresses with lower intensity and a concentration of compressive stresses in the middle region. The simplified three-dimensional model proved useful for assessing the distribution of stresses on the TMJ disc induced by the chincup therapy. PMID:29160348

Full Text Available The acceptance and respect of the rules governing society and the family unit are essential pillars for the development of a therapeutic program for people with substance dependence disorders. This study proposes a double objective using the scales of the MMPI-2 detectors of mismatches emphasising: what information can provide and what the diagnostic accuracy of the MMPI-2 is to assess these mismatches. As a reference, psychopathic deviation (Pd, social introversion (Si, antisocial practices (ASP, social responsibility (Re, social unrest (SOD, introversion/low positive emotion (PSY-INTR, family problems (FAM, and conjugal stress (MDS were taken. Of the 226 participants, 113 are people with substance dependence and 113 have no dependence or any pathology. Their differences and diagnostic accuracy through the ROC curve were analysed. The results showed different contribution and diagnostic accuracy of the scales.

Hepcidin is the key regulator of iron homeostasis but data are limited regarding its temporal response to iron therapy, and response to intravenous versus oral iron. In the 56-week, open-label, multicenter, prospective, randomized FIND-CKD study, 626 anemic patients with non-dialysis dependent chronic kidney disease (ND-CKD) and iron deficiency not receiving an erythropoiesis stimulating agent were randomized (1:1:2) to intravenous ferric carboxymaltose (FCM), targeting higher (400-600μg/L) or lower (100-200μg/L) ferritin, or to oral iron. Serum hepcidin levels were measured centrally in a subset of 61 patients. Mean (SD) baseline hepcidin level was 4.0(3.5), 7.3(6.4) and 6.5(5.6) ng/mL in the high ferritin FCM (n = 17), low ferritin FCM (n = 16) and oral iron group (n = 28). The mean (SD) endpoint value (i.e. the last post-baseline value) was 26.0(9.1),15.7(7.7) and 16.3(11.0) ng/mL, respectively. The increase in hepcidin from baseline was significantly smaller with low ferritin FCM or oral iron vs high ferritin FCM at all time points up to week 52. Significant correlations were found between absolute hepcidin and ferritin values (r = 0.65, p<0.001) and between final post-baseline increases in both parameters (r = 0.70, p<0.001). The increase in hepcidin levels over the 12-month study generally mirrored the cumulative iron dose in each group. Hepcidin and transferrin saturation (TSAT) absolute values showed no correlation, although there was an association between final post-baseline increases (r = 0.42, p<0.001). Absolute values (r = 0.36, p = 0.004) and final post-baseline increases of hepcidin and hemoglobin (p = 0.30, p = 0.030) correlated weakly. Baseline hepcidin levels were not predictive of a hematopoietic response to iron therapy. In conclusion, hepcidin levels rose in response to either intravenous or oral iron therapy, but the speed and extent of the rise was greatest with intravenous iron targeting a higher ferritin level. However neither the

The aim of the present study was to evaluate the effect of group psychotherapy with transactional analysis (TA) approach on emotional intelligence (EI), executive functions and substance dependency among drug-addicts at rehabilitation centers in Mashhad city, Iran, in 2013. In this quasi-experimental study with pretest, posttest, case- control stages, 30 patients were selected from a rehabilitation center and randomly divided into two groups. The case group received 12 sessions of group psychotherapy with transactional analysis approach. Then the effects of independent variable (group psychotherapy with TA approach) on EI, executive function and drug dependency were assessed. The Bar-on test was used for EI, Stroop test for measuring executive function and morphine test, meth-amphetamines and B2 test for evaluating drug dependency. Data were analyzed using multifactorial covariance analysis, Levenes' analysis, MANCOVA, t-student and Pearson correlation coefficient tests t with SPSS software. Our results showed that group psychotherapy with the TA approach was effective in improving EI, executive functions and decreasing drug dependency (P addicts and prevents addiction recurrence by improving the coping capabilities and some mental functions of the subjects. However, there are some limitations regarding this study including follow-up duration and sample size.

Assessment of importance of elements for systems that condition depends on the sequence of elements failures

International Nuclear Information System (INIS)

Povyakalo, A.A.

1996-01-01

This paper proposes new general formulas for calculation of indices of elements importance for systems whose condition depends on sequence of elements failures. These systems have been called as systems with memory of failures (M-systems). Techniques existing for assessment of importance of elements are based on the Bool's models of system reliability, for which it is significant to suggest, that in every period of time system state depends only on a combination of states of elements at that very moment of time. These systems have been called as combinational systems (C-systems). Reliability of M-systems at any moment of operating time is a functional having distributions of elements time before failure as its arguments. Bool's models and methods of assessment of element importance, based on these models, are not appropriate for these systems. Pereguda and Povyakalo proposed the new techniques for assessment of elements importance for PO-SS systems that includes Protection Object (PO) and Safety System (PO). PO-SS system is an example of M-system. That technique is used at this paper as a basis for more general consideration. It has been shown that technique proposed for assessment of elements importance for M-systems has well-known Birnbaum's method as its particular case. Also the system with double protection is considered as an example

In the last two decades, monoclonal antibodies have revolutionized the therapy of cancer patients. Although antibody therapy has continuously been improved, still a significant number of patients do not benefit from antibody therapy. Therefore, rational optimization of the antibody molecule by Fc engineering represents a major area of translational research to further improve this potent therapeutic option. Monoclonal antibodies are able to trigger a variety of effector mechanisms. Especially Fc-mediated effector functions such as antibody-dependent cell-mediated cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP), and complement- dependent cytotoxicity (CDC) are considered important in antibody therapy of cancer. Novel mechanistic insights into the action of monoclonal antibodies allowed the development of various Fc engineering approaches to modulate antibodies' effector functions. Strategies in modifying the Fc glycosylation profile (Fc glyco-engineering) or approaches in engineering the protein backbone (Fc protein engineering) have been intensively evaluated. In the current review, Fc engineering strategies resulting in improved ADCC, ADCP and CDC activity are summarized and discussed.

Purpose: To develop standard (SPCA) and regularized (RPCA) principal component analysis models of anatomical changes from daily cone beam CTs (CBCTs) of head and neck (H&N) patients and assess their potential use in adaptive radiation therapy, and for extracting quantitative information for treatment response assessment. Methods: Planning CT images of ten H&N patients were artificially deformed to create “digital phantom” images, which modeled systematic anatomical changes during radiation therapy. Artificial deformations closely mirrored patients’ actual deformations and were interpolated to generate 35 synthetic CBCTs, representing evolving anatomy over 35 fractions. Deformation vector fields (DVFs) were acquired between pCT and synthetic CBCTs (i.e., digital phantoms) and between pCT and clinical CBCTs. Patient-specific SPCA and RPCA models were built from these synthetic and clinical DVF sets. EigenDVFs (EDVFs) having the largest eigenvalues were hypothesized to capture the major anatomical deformations during treatment. Results: Principal component analysis (PCA) models achieve variable results, depending on the size and location of anatomical change. Random changes prevent or degrade PCA’s ability to detect underlying systematic change. RPCA is able to detect smaller systematic changes against the background of random fraction-to-fraction changes and is therefore more successful than SPCA at capturing systematic changes early in treatment. SPCA models were less successful at modeling systematic changes in clinical patient images, which contain a wider range of random motion than synthetic CBCTs, while the regularized approach was able to extract major modes of motion. Conclusions: Leading EDVFs from the both PCA approaches have the potential to capture systematic anatomical change during H&N radiotherapy when systematic changes are large enough with respect to random fraction-to-fraction changes. In all cases the RPCA approach appears to be more

The effectiveness of cognitive-behaviour therapy with young people may be influenced by a young person's capacity for self-reflection and insight. Clinicians who assess clients' proficiencies in these cognitive capacities can better tailor cognitive and behavioural techniques to the client, facilitating engagement and enhancing treatment outcome. It is therefore important that sound instruments for assessing self-reflection and insight in young people are available. The aim of the current study was to translate and adapt the Self-Reflection and Insight Scale (SRIS) for use with a child and adolescent population (Study 1), and to evaluate the psychometric properties of the resulting measure, the Self-Reflection and Insight Scale for Youth (SRIS-Y; Study 2). In Study 1 (n=145), the comprehensibility of the SRIS-Y was assessed in a community sample of children and adolescents. Study 2 (n=215) then explored the reliability and structural, convergent, and divergent validity of the SRIS-Y. The SRIS-Y was found to be comprehensible to young people, and had good reliability and structural validity. It appears that the SRIS-Y is a sound instrument for assessing therapy-relevant cognitive capacities in young people, of potential benefit in both research and clinical contexts. Future research foci include the predictive validity of the instrument.

Full Text Available Objectives. To determine risk factors associated with ventilator dependence in patients with ventilator-associated pneumonia (VAP. Study Design. A retrospective study was conducted at Chang Gung Memorial Hospital, Kaohsiung, from January 1, 2007 to January 31, 2008. Methods. This study evaluated 163 adult patients (aged ≥18 years. Eligibility was evaluated according to the criterion for VAP, Sequential Organ Failure Assessment (SOFA score, Acute Physiological Assessment and Chronic Health Evaluation II (APACHE II score. Oxygenation index, underlying comorbidities, septic shock status, previous tracheostomy status, and factors related to pneumonia were collected for analysis. Results. Of the 163 VAP patients in the study, 90 patients survived, yielding a mortality rate of 44.8%. Among the 90 surviving patients, only 36 (40% had been weaned off ventilators at the time of discharge. Multivariate logistic regression analysis was used to identify underlying factors such as congestive cardiac failure (P=0.009, initial high oxygenation index value (P=0.04, increased SOFA scores (P=0.01, and increased APACHE II scores (P=0.02 as independent predictors of ventilator dependence. Results from the Kaplan-Meier method indicate that initial therapy with antibiotics could increase the ventilator weaning rate (log Rank test, P<0.001. Conclusions. Preexisting cardiopulmonary function, high APACHE II and SOFA scores, and high oxygenation index were the strongest predictors of ventilator dependence. Initial empiric antibiotic treatment can improve ventilator weaning rates at the time of discharge.

The cure of cancer is still a formidable challenge in medical science. Long-known modalities including surgery, chemotherapy and radiotherapy are successful in a number of cases; however, invasive, metastasized and inaccessible tumors still pose an unresolved and ongoing problem. Targeted therapies designed to locate, detect and specifically kill tumor cells have been developed in the past three decades as an alternative to treat troublesome cancers. Most of these therapies are either based on antibody-dependent cellular cytotoxicity, targeted delivery of cytotoxic drugs or tumor site-specific activation of prodrugs. The latter is a two-step procedure. In the first step, a selected enzyme is accumulated in the tumor by guiding the enzyme or its gene to the neoplastic cells. In the second step, a harmless prodrug is applied and specifically converted by this enzyme into a cytotoxic drug only at the tumor site. A number of targeting systems, enzymes and prodrugs were investigated and improved since the concept was first envisioned in 1974. This review presents a concise overview on the history and latest developments in targeted therapies for cancer treatment. We cover the relevant technologies such as antibody-directed enzyme prodrug therapy (ADEPT), gene-directed enzyme prodrug therapy (GDEPT) as well as related therapies such as clostridial- (CDEPT) and polymer-directed enzyme prodrug therapy (PDEPT) with emphasis on prodrug-converting enzymes, prodrugs and drugs.

This study was to objectively assess the effect of music therapy on patients with advanced disease. Two hundred patients with chronic and/or advanced illnesses were prospectively evaluated. The effects of music therapy on these patients are reported. Visual analog scales, the Happy/Sad Faces Assessment Tool, and a behavior scale recorded pre- and post-music therapy scores on standardized data collection forms. A computerized database was used to collect and analyze the data. Utilizing the Wilcoxon signed rank test and a paired t test, music therapy improved anxiety, body movement, facial expression, mood, pain, shortness of breath, and verbalizations. Sessions with family members were also evaluated, and music therapy improved families' facial expressions, mood, and verbalizations. All improvements were statistically significant (Pmusic therapy. Objective data were obtained for a large number of patients with advanced disease. This is a significant addition to the quantitative literature on music therapy in this unique patient population. Our results suggest that music therapy is invaluable in palliative medicine.

Visual changes may develop in patients receiving radiation therapy for malignant neoplasms in and about the optic nerve and anterior visual pathway. Cases have been studied using a series of psychophysical tests, including kinetic perimetry, increment threshold determinations, Flashing Repeat Static Test, and sustained- and transient-like functions. A characteristic time-dependent reduction in sensitivity has been identified in these patients. This finding, in addition to the presence of nerve fiber bundle defects, appears to place the pathologic changes in the axon of the ganglion cell posterior to the lamina cribrosa. Any change in the sustained- and transient-like functions, the organization of which appears to be in the neural retina, was seen only if a concomitant radiation retinopathy was identified

To provide an overview of (1) the consistency of Type 2 Diabetes Clinical Practice Guidelines recommendations on the delivery of nutrition therapy and (2) Clinical Practice Guideline quality. Large international clinical practice guideline repositories, diabetes organisation websites, and electronic databases (Pubmed, Scopus), were searched to identify Clinical Practice Guidelines for adults with type 2 diabetes published 2005 to August 2014. Recommendations on the delivery of nutrition therapy were extracted and inductive content analysis was used to analyse consistency. Two researchers independently assessed guideline quality using the AGREE II tool. Nine topics were identified from the recommendations. Overall the consistency of the recommendations was related to guideline type. Compared with nutrition-specific guidelines, the broad ones had a broader focus and included more patient-focused recommendations. The ten Clinical Practice Guidelines assessed included six broad guidelines and four nutrition specific guidelines. Based on AGREE II analysis, the broad guidelines were higher quality than nutrition-specific ones. Broad Clinical Practice Guidelines were higher quality and included more patient-focused recommendations than nutrition-specific ones. Our findings suggest a need for nutrition-specific guidelines to be modified to include greater patient-focus, or for practitioners delivering nutrition therapy to adopt broad Clinical Practice Guidelines.

2013-01-01

In this book, the authors present cutting-edge model-driven techniques for modeling and analysis of software dependability. Most of them are based on the use of UML as software specification language. From the software system specification point of view, such techniques exploit the standard extension mechanisms of UML (i.e., UML profiling). UML profiles enable software engineers to add non-functional properties to the software model, in addition to the functional ones. The authors detail the state of the art on UML profile proposals for dependability specification and rigorously describe the t

Nucleos(t)ide analogue (NA) therapy has been reported to reduce the risk of hepatocellular carcinoma (HCC) development in patients with chronic hepatitis B (CHB). However, even during NA therapy, development of HCC has been observed in patients with CHB. Therefore, we clarified the predictive power of clinical factors for HCC incidence using receiver operating characteristic (ROC) analysis that takes time dependence into account. A total of 539 patients with CHB treated with NAs were enrolled. Univariate, multivariate, and time-dependent ROC curves for clinical factors associated with the development of HCC were analyzed. Eighty-one patients developed HCC during the follow-up period (median duration, 5.9 years). α-fetoprotein (AFP) and FIB-4 index at 24 weeks from the initiation of treatment and sex were significantly associated with HCC incidence according to the log-rank test. Cox proportional hazards models including the covariates of sex, hepatitis B genotype, basal core promoter mutations, AFP at 24 weeks, and FIB-4 index at 24 weeks showed that FIB-4 index >2.65 (HR, 5.03; 95% CI, 3.06-8.26; P patients with CHB receiving NA therapy is a risk factor for developing HCC. The FIB-4 index is an excellent predictor of HCC development. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Parental competencies have influence on the professional health care needs of a child and its caregivers. One reason for this is the influence of parental competencies on the healthy development of the child. This applies especially to infants and young children. In order to develop their inborn abilities to regulate themselves and their behaviour, infants and young children are dependent on the perception of and appropriate response to their behaviour by the persons they are most closely attached to. The differentiation of self-regulating abilities is a precondition for a healthy development. The current rise of sleeping and feeding disorders, as well as interaction problems among infants and young children, indicates that parents are increasingly dependent on support in the perception and development of their parental competencies. Paediatric nurses can make an important contribution to this, where a concept of parental competencies, defined by nursing professionals, is available. The Theory of Dependent-Care and especially the concept of Dependent-Care Agency will be presented in this paper. It will be examined how they can provide a theoretical framework for the systematic assessment, support, and promotion of parental competencies by paediatric nurses. To conclude, issues for further investigation of parental Dependent-Care Agency and the necessity for a more detailed conceptualisation of the Theory of Dependent-Care will be demonstrated.

To evaluate the performance of contrast-enhanced spectral mammography (CESM) compared to MRI in the assessment of tumor response in breast cancer patients undergoing neoadjuvant systemic therapy (NST). The institutional review board approved this study. From September 2014 to June 2017, we identified patients with pathologically confirmed invasive breast cancer who underwent NST. All patients had both CESM and MRI performed pre- and post-NST with pathological assessment after surgical management. Size of residual malignancy on post-NST CESM and MRI was compared with surgical pathology. Lin concordance and Pearson correlation coefficient were used to assess agreement. Bland-Altman plots were used to visualize the differences between tumor size on imaging and pathology. Sixty-five patients were identified. Mean age was 52.7 (range 30-76) years. Type of NST included chemotherapy in 53 (82%) and endocrine therapy in 12 (18%). Mean tumor size after NST was 14.6 (range 0-105) mm for CESM and 14.2 mm (range 0-75 mm) for MRI compared with 19.6 (range 0-100) mm on final surgical pathology. Equivalence tests demonstrated that mean tumor size measured by CESM (p = 0.009) or by MRI (p = 0.01) was equivalent to the mean tumor size measured by pathology within - 1 and 1-cm range. Comparing CESM versus MRI for assessment of complete response, the sensitivity was 95% versus 95%, specificity 66.7% versus 68.9%, positive predictive value 55.9% versus 57.6%, and negative predictive value 96.7% versus 96.9% respectively. CESM was comparable to MRI in assessing residual malignancy after completion of NST.

This paper introduces an approach to assess and improve the time-dependent resilience of urban infrastructure systems, where resilience is defined as the systems' ability to resist various possible hazards, absorb the initial damage from hazards, and recover to normal operation one or multiple times during a time period T. For different values of T and its position relative to current time, there are three forms of resilience: previous resilience, current potential resilience, and future potential resilience. This paper mainly discusses the third form that takes into account the systems' future evolving processes. Taking the power transmission grid in Harris County, Texas, USA as an example, the time-dependent features of resilience and the effectiveness of some resilience-inspired strategies, including enhancement of situational awareness, management of consumer demand, and integration of distributed generators, are all simulated and discussed. Results show a nonlinear nature of resilience as a function of T, which may exhibit a transition from an increasing function to a decreasing function at either a threshold of post-blackout improvement rate, a threshold of load profile with consumer demand management, or a threshold number of integrated distributed generators. These results are further confirmed by studying a typical benchmark system such as the IEEE RTS-96. Such common trends indicate that some resilience strategies may enhance infrastructure system resilience in the short term, but if not managed well, they may compromise practical utility system resilience in the long run.

Purpose: To evaluate quality of life (QoL), an important outcome owing to poor long-term survival, after stereotactic body radiation therapy (SBRT) to the liver. Methods and Materials: Patients (n=222) with hepatocellular carcinoma (HCC), liver metastases, or intrahepatic cholangiocarcinoma and Child-Pugh A liver function received 24-60 Gy of 6-fraction image-guided SBRT. Prospective QoL assessment was completed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ-C30) and/or Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep, version 4) questionnaires at baseline and 1, 3, 6, and 12 months after treatment. Ten HCC patients with Child-Pugh B liver function were also treated. Results: The QLQ-C30 was available for 205 patients, and 196 completed the FACT-Hep. No difference in baseline QoL (P=.17) or overall survival (P=.088) was seen between the HCC, liver metastases, and intrahepatic cholangiocarcinoma patients. Appetite loss and fatigue measured by the QLQ-C30 clinically and statistically worsened by 1 month after treatment but recovered by 3 months. At 3 and 12 months after treatment, respectively, the FACT-Hep score had improved relative to baseline in 13%/19%, worsened in 36%/27%, and remained stable in 51%/54%. Using the QLQ-C30 Global Health score, QoL improved in 16%/23%, worsened in 34%/39%, and remained stable in 50%/38% at 3 and 12 months, respectively. Median survival was 17.0 months (95% confidence interval [CI] 12.3-19.8 months). Higher baseline scores on both FACT-Hep and QLQ-C30 Global Health were associated with improved survival. Hazard ratios for death, per 10-unit decrease in QoL, were 0.90 (95% CI 0.83-0.98; P=.001) and 0.88 (95% CI 0.82-0.95; P=.001), respectively. Tumor size was inversely correlated with survival. Conclusions: Liver SBRT temporarily worsens appetite and fatigue, but not overall QoL. Stereotactic body radiation therapy is well tolerated and warrants

Full Text Available Introduction: This study investigated the role of thought suppression, meta- cognitive factors, and negative emotions in predicting of substance dependency disorder. Method: Subjects were 70 patients with substance dependence disorder and 70 normal individuals (total 140. Substance dependants were selected of outpatient treatment centers and the normal sample was selected of the general population too. Sampling methods in both samples were convenience sampling. All people were assessed by MCQ-30, White Bear Suppression Inventory, and Beck’s Anxiety and Depression Questionnaires. For data analysis, discriminant analysis were used. Results: Negative meta-cognitive beliefs about worry, depression, and thought suppression were the most significant predictors of substance dependence disorder. Conclusion: Through meta-cognitive beliefs, thought suppression and negative emotion (especially depression, substance dependency disorder can be predicted. Based on this model can be used to take a substance dependency disorder prevention approach and psychotherapy approach (based on cognitive and meta-cognitive therapies. In addition, the findings of this research can be applied in clinical and counseling environments to help substance dependant clients.

Horticultural therapy is defined as the process of utilising fruits, vegetables, flowers and plants facilitated by a trained therapist or healthcare provider, to achieve specific treatment goals or to simply improve a person's well-being. It can be used for therapy or rehabilitation programs for cognitive, physical, social, emotional, and recreational benefits, thus improving the person's body, mind and spirit. Between 5% to 15% of people with schizophrenia continue to experience symptoms in spite of medication, and may also develop undesirable adverse effects, horticultural therapy may be of value for these people. To evaluate the effects of horticultural therapy for people with schizophrenia or schizophrenia-like illnesses compared with standard care or other additional psychosocial interventions. We searched the Cochrane Schizophrenia Group Trials Register (Janurary 2013) and supplemented this by contacting relevant study authors, and manually searching reference lists. We included one randomised controlled trial (RCT) comparing horticultural therapy plus standard care with standard care alone for people with schizophrenia. We reliably selected, quality assessed and extracted data. For continuous outcomes, we calculated a mean difference (MD) and for binary outcomes we calculated risk ratio (RR), both with 95% confidence intervals (CI). We assessed risk of bias and created a 'Summary of findings' table using the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) approach. We included one single blind study (total n = 24). The overall risk of bias in the study was considered to be unclear although the randomisation was adequate. It compared a package of horticultural therapy which consisted of one hour per day of horticultural activity plus standard care with standard care alone over two weeks (10 consecutive days) with no long-term follow-up. Only two people were lost to follow-up in the study, both in the horticultural therapy group (1 RCT

Intrapleural therapy with a combination of tissue plasminogen activator (tPA) 10 mg and DNase 5 mg administered twice daily has been shown in randomized and open-label studies to successfully manage over 90% of patients with pleural infection without surgery. Potential bleeding risks associated with intrapleural tPA and its costs remain important concerns. The aim of the ongoing Alteplase Dose Assessment for Pleural infection Therapy (ADAPT) project is to investigate the efficacy and safety of dose de-escalation for intrapleural tPA. The first of several planned studies is presented here. To evaluate the efficacy and safety of a reduced starting dose regimen of 5 mg of tPA with 5 mg of DNase administered intrapleurally for pleural infection. Consecutive patients with pleural infection at four participating centers in Australia, the United Kingdom, and New Zealand were included in this observational, open-label study. Treatment was initiated with tPA 5 mg and DNase 5 mg twice daily. Subsequent dose escalation was permitted at the discretion of the attending physician. Data relating to treatment success, radiological and systemic inflammatory changes (blood C-reactive protein), volume of fluid drained, length of hospital stay, and treatment complications were extracted retrospectively from the medical records. We evaluated 61 patients (41 males; age, 57 ± 16 yr). Most patients (n = 58 [93.4%]) were successfully treated without requiring surgery for pleural infection. Treatment success was corroborated by clearance of pleural opacities visualized by chest radiography (from 42% [interquartile range, 22-58] to 16% [8-31] of hemithorax; P < 0.001), increase in pleural fluid drainage (from 175 ml in the 24 h preceding treatment to 2,025 ml [interquartile range, 1,247-2,984] over 72 h of therapy; P <  0.05) and a reduction in blood C-reactive protein (P < 0.05). Seven patients (11.5%) had dose escalation of tPA to 10 mg. Three patients underwent
