    Women with breast cancer require information about their cancer and its treatment during the process of treatment decision-making, yet it is unclear if there are barriers to information support. This study explores the experience of making treatment decisions in breast cancer, paying particular attention to the barriers experienced to the provision of information. Using a grounded theory methodology, semi-structured interviews were conducted with 22 women with invasive breast cancer exploring the experience of treatment decision-making. Data was organized using ATLAS.ti software and analyzed using constant comparisons. Analysis of the data showed that barriers to cancer and treatment information include intrapersonal and interpersonal communication challenges (emotional distress, patient-provider communication, "making it personal," access to information) which reside at different levels of the breast cancer experience (individual, dyad, group, organization). A model is provided to depict this experience. Women want information about their cancer and its treatment and experience barriers to information provision at various levels. Satisfactory information provision cannot occur without addressing barriers at every level. Utilizing interprofessional models of care may minimize existing barriers to information provision and empower patients to make satisfying treatment decisions that are consistent with their individual wishes.

    Full Text Available Parental differential treatment is an important feature of non-shared family environment which contributes to the development of behavioural differences between siblings growing up in the same family. To investigate the frequency, direction, and patterns of parental differential treatment of siblings in Slovene families, mothers and fathers of 93 sibling-pairs in early/middle childhood provided self-reports in a two-wave longitudinal study. Most of the parents reported on low levels of differential treatment, predominantly expressing somewhat more affection and control towards the older than towards the younger sibling. Over a one-year time period, the average frequency of parental differential treatment did not change significantly, whereas the stability was estimated as moderate for maternal and low for paternal assessments. Maternal and paternal self-ratings were moderately correlated. However, the mothers reported on somewhat higher levels of differential control and (only in wave 1 affection than the fathers. Nearly half of the families were characterized by a congruent pattern of parental differential treatment indicating that both parents showed more affection and control towards the older of the two siblings. A complementary family pattern reflecting an opposite direction of maternal and paternal differential treatment emerged in approximately a quarter of the participating families.

    2002-12-01

    This study assessed characteristics of psychiatric patients for whom financial considerations affected the provision of "optimal" treatment. Psychiatrists reported that for 33.8 percent of 1,228 patients from a national sample, financial considerations such as managed care limitations, the patient's personal finances, and limitations inherent in the public care system adversely affected the provision of optimal treatment. Patients were more likely to have their treatment adversely affected by financial considerations if they were more severely ill, had more than one behavioral health disorder or a psychosocial problem, or were receiving treatment under managed care arrangements. Patients for whom financial considerations affect the provision of optimal treatment represent a population for whom access to treatment may be particularly important.

    Full Text Available Differential diagnosis in muscle pains often presents great difficulties so all existing signs of the disease should be carefully considered to make its diagnosis and to prescribe adequate therapy. The paper considers the causes of muscle pains, laboratory and instrumental studies (immunological tests, determination of the level of specific muscular enzymes, primarily creatine phosphokinase – CPK, etc., and the main reasons for enhanced plasma CPK activity. It also describes acute and chronic mialgias associated with enhanced plasma CPK activity, as well as diseases in which mialgias are related to the normal level of CPK, myofascial syndrome (MFS and fibromyalgia (FM in particular. The characteristic features of MFS are given in its diagnostic criteria. It is stated that a differential diagnosis should be made between MFS and major muscle pain-associated abnormalities, such as polymyalgia rheumatica, FM, etc. Diagnosticcriteria for polymyalgia rheumatica are given. A MFS treatment algorithm is presented. Local exposure methods applied to altered musculoligamentous structures in combination with myorelaxants and non-steroidal anti-inflammatory drugs assume paramount importance in MFS.

  11. Elliptic differential equations theory and numerical treatment

    CERN Document Server

    Hackbusch, Wolfgang

    2017-01-01

    This book simultaneously presents the theory and the numerical treatment of elliptic boundary value problems, since an understanding of the theory is necessary for the numerical analysis of the discretisation. It first discusses the Laplace equation and its finite difference discretisation before addressing the general linear differential equation of second order. The variational formulation together with the necessary background from functional analysis provides the basis for the Galerkin and finite-element methods, which are explored in detail. A more advanced chapter leads the reader to the theory of regularity. Individual chapters are devoted to singularly perturbed as well as to elliptic eigenvalue problems. The book also presents the Stokes problem and its discretisation as an example of a saddle-point problem taking into account its relevance to applications in fluid dynamics.

    Full Text Available Background: Infertility may have many emotional and psychological implications on infertilecouples. So far, different methods for reducing anxiety in infertile couples have been evaluated. Thegoal of this study is to evaluate the effect of provision of information regarding infertility treatmentto infertile couples on their anxiety levels.Materials and Methods: This study was conducted as a before and after clinical trial. Forty-twoindividuals were considered as cases and 40 as controls. In order to evaluate anxiety and depressionin participants, the Hamilton Anxiety and Depression Scale (HADS questionnaire was used. Theintervention group received information about infertility treatment through a two hour face-to-facemeeting and was provided with a brochure. Anxiety level was assessed at the time of admission,immediately after the session and two weeks later. Assessment was performed twice for the controlgroup; once at the time of admission and secondly, two weeks later.Results: Our results show that receiving information about infertility treatment significantlydecreases anxiety among infertile couples two weeks post-training. This decline does not have asignificant correlation with age, sex, education level of the couple, and neither with the durationnor the cause of infertility. Providing information does not have any significant effect on the rate ofdepression among couples.Conclusion: It is recommended that provision of information regarding infertility treatmentmethods should be considered as a means of decreasing anxiety among infertile couples who referto infertility treatment centers.

  15. A New Resources Provisioning Method Based on QoS Differentiation and VM Resizing in IaaS

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available In order to improve the host energy efficiency in IaaS, we proposed an adaptive host resource provisioning method, CoST, which is based on QoS differentiation and VM resizing. The control model can adaptively adjust control parameters according to real time application performance, in order to cope with changes in load. CoST takes advantage of the fact that different types of applications have different sensitivity degrees to performance and cost. It places two different types of VMs on the same host and dynamically adjusts their sizes based on the load forecasting and QoS feedback. It not only guarantees the performance defined in SLA, but also keeps the host running in energy-efficient state. Real Google cluster trace and host power data are used to evaluate the proposed method. Experimental results show that CoST can provide performance-sensitive application with a steady QoS and simultaneously speed up the overall processing of performance-tolerant application by 20~66%. The host energy efficiency is significantly improved by 7~23%.

    Distant metastases occur in less than 10% of patients with differentiated thyroid carcinoma. In these patients, overall survival at 10 years is considerably reduced. Whereas cure is the initial goal of treatment, stabilisation of the disease and management of symptoms have become the primary objective in many patients with persistent radio-iodine refractory progressive disease. In the last decade, several targeted therapies have shown encouraging results in patients with advanced disease. The objective of this review is to describe the characteristics, diagnosis, overall survival, and the local and systemic available treatments for patients with distant metastases from differentiated thyroid cancer.

    Molar-Incisor Hypomineralisation (MIH) is a congenital disease which increases in prevalence. It affects permanent first molars and, often to a lesser degree, permanent incisors with variable severity. The aetiology is unknown, but different hypotheses have been advanced. Differential diagnosis is mandatory not to confound MIH with other diseases. Treatment consists in a minimally invasive approach by reinforcing and protecting the existing dental structure. In more severe cases, restorative treatment may be indicated.

    2018-01-01

    Meeting the psychosocial needs of patients with cancer has been recognised as a priority within oncology care for several decades. Many approaches that address these needs have been developed and described; however, until recently much of this work had focused on patients during treatment and end-of-life care. With continued improvement in therapies, the population of cancer survivors who can expect to live for 5 or more years after cancer diagnosis has increased dramatically, as have associated concerns about how to meet their medical, psychosocial, and health behaviour needs after treatment. Guidelines and models for general survivorship care routinely address psychosocial needs, and similar guidelines for psychosocial care of patients with cancer are being extended to address the needs of survivors. In this Series paper, we summarise the existing recommendations for the provision of routine psychosocial care to survivors, as well as the challenges present in providing this care. We make specific recommendations for the integration of psychosocial services into survivorship care. PMID:28049576

    2011-04-01

    In this study we examined patterns of mothers' and fathers' differential affection and discipline toward 2 adolescent offspring in 243 Mexican-origin families. Grounding our work in a family systems perspective, we used interparental patterns of differential treatment as an index of the coparental alliance and tested their associations with parents' reports of familism values, traditional gender role attitudes, and cultural orientations. We also sought to replicate prior research on European American samples linking interparental patterns of differential treatment to marital qualities (coparenting satisfaction, love, and conflict) and adolescent depressive symptoms and risky behaviors. Three interparental patterns emerged: families in which both mothers and fathers treated their 2 offspring equally, incongruent families in which 1 parent treated both offspring equally while the other parent favored 1 offspring, and congruent families in which both parents favored the same offspring. Most parents reported equal treatment, but others fell into the incongruent affection (30%), incongruent discipline (45%), and congruent discipline (16%) groups. Mixed model analyses of variances revealed that in families in which mothers and fathers both treated their offspring equally, parents reported higher familism values, more traditional gender role attitudes, and relatively stronger orientations to Mexican than Anglo culture. Consistent with previous research, interparental incongruence was associated with less positive marital qualities and more adolescent adjustment problems. Discussion focuses on the role of culture in shaping coparenting and the processes through which these coparenting dynamics are linked to marital and youth adjustment.

    Objective To investigate whether repeated morphine exposure or prolonged withdrawal could influence operant and spatial learning differentially. Methods Animals were chronically treated with morphine or subjected to morphine withdrawal. Then, they were subjected to two kinds of learning: operant conditioning and spatial learning.Results The acquisition of both simple appetitive and cued operant learning was impaired after repeated morphine treatment. Withdrawal for 5 weeks alleviated the impairments. Single morphine exposure disrupted the retrieval of operant memory but had no effect on rats after 5-week withdrawal. Contrarily, neither chronic morphine exposure nor 5-week withdrawal influenced spatial learning task of the Morris water maze. Nevertheless, the retrieval of spatial memory was impaired by repeated morphine exposure but not by 5-week withdrawal. Conclusion These observations suggest that repeated morphine exposure can influence different types of learning at different aspects, implicating that the formation of opiate addiction may usurp memory mechanisms differentially.

  4. Starvation Based Differential Chemotherapy: A Novel Approach for Cancer Treatment

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available Cancer patients undergoing chemotherapy treatment are advised to increase food intake to overcome the therapy-induced side effects, and weight loss. Dietary restriction is known to slow down the aging process and hence reduce age-related diseases such as cancer. Fasting or short-term starvation is more effective than dietary restriction to prevent cancer growth since starved cells switch off signals for growth and reproduction and enter a protective mode, while cancer cells, being mutated, are not sensitized by any external growth signals and are not protected against any stress. This phenomenon is known as differential stress resistance (DSR. Nutrient signaling pathways involving growth hormone/insulin-like growth factor-1 axis and its downstream effectors, play a key role in DSR in response to starvation controlling the other cell maintenance systems, such as autophagy and apoptosis, that are related to the tumorigenesis. Yeast cells lacking these effectors are better protected against oxidative stress compared to normal cells. In the same way, starvation protects many cell lines and mice against high-dose chemotherapeutic drugs. According to a series of studies, fasting results in overall reduction in chemotherapy side effects in cancer patients. Data shows that starvation-dependent differential chemotherapy is safe, feasible and effective in cancer treatment, but the possible side effects of starvation limit its efficacy. However, further studies and clinical trials may result in its implementation in cancer treatment.

    Full Text Available There are a lot of works, which are devoted to the study of acne, but these data are often contradictory on the issue of interrelationship and interdependence of clinical manifestations, course and some factors in the pathogenesis of acne and candida infection. Aim of the research was to study the effect of the recommended differentiated therapy on the pathogenetic disorders in patients with acne and concomitant Candida infection. Methods and results. 120 patients with acne were examined. In 100 of them concomitant skin malasseziosis was set in the form of pityriasis rosea, kerosis, comedones, folliculitis, seborrhea, multicolored zoster, with some features, as well as candidiasis. Methods of the research – bacterioscopic, bacteriological, study of skin oiliness and moisture, skin pH, the level of Ca ++, parathyroid hormone and calcitonin. In patients with acne significant shifts in the composition of water-lipid mantle, increased oiliness and decreased moisture of skin, pH changes with a shift to the alkaline side were revealed, the most pronounced – in acne patients with Candida infection. The content of Ca ++ in the organism, as well as parathyroid hormone and calcitonin was increased and also the most indicative it was in patients with acne and concomitant Candida infection. After the comparative analysis on the basis of different levels of clinical and laboratory violations two clinical-therapeutic groups were distinguished, in accordance with that the differentiated therapy offered by us was conducted. Increased oiliness and Рh of skin, decline of moisture before the treatment, especially in patients with III and IV stages of acne, complicated by Candida infection, were normalized after treatment, unlike in patients treated traditionally. Conclusion. After treatment intensity of microbal colonization and also microbal associations of skin was diminished, the level of Ca++, parathyroid hormone and calcitonin went down.

    2012-12-01

    Actinomycosis is an uncommon chronic granulomatous disease that presents as a slowly progressive, indolent, indurated infiltration with multiple abscesses, fistulas, and sinuses. The purpose of this article is to report on a case of actinomycosis with clinical findings similar to periodontitis. A 46-year-old female presented with recurrent throbbing pain on the right first and second molar of the mandible three weeks after root planing. Exploratory flap surgery was performed, and the bluish-gray tissue fragment found in the interproximal area between the two molars was sent for histopathology. The diagnosis from the biopsy was actinomycosis. The clinical and radiographic manifestations of this case were clinically indistinguishable from periodontitis. The patient did not report any symptoms, and she is scheduled for a follow-up visit. The present study has identified periodontitis-mimicking actinomycosis. Actinomycosis should be included in the differential diagnosis in cases with periodontal pain and inflammation that do not respond to nonsurgical treatment for periodontitis. More routine submissions of tissue removed from the oral cavity for biopsies may be beneficial for differential diagnosis.

    Full Text Available Abstract Background Public-private partnerships (PPP could be effective in scaling up services. We estimated cost and cost-effectiveness of different PPP arrangements in the provision of tuberculosis (TB treatment, and the financing required for the different models from the perspective of the provincial TB programme, provider, and the patient. Methods Two different models of TB provider partnerships are evaluated, relative to sole public provision: public-private workplace (PWP and public-private non-government (PNP. Cost and effectiveness data were collected at six sites providing directly observed treatment (DOT. Effectiveness for a 12-month cohort of new sputum positive patients was measured using cure and treatment success rates. Provider and patient costs were estimated, and analysed according to sources of financing. Cost-effectiveness is estimated from the perspective of the provider, patient and society in terms of the cost per TB case cured and cost per case successfully treated. Results Cost per case cured was significantly lower in PNP (US $354–446, and comparable between PWP (US $788–979 and public sites (US $700–1000. PPP models could significantly reduce costs to the patient by 64–100%. Relative to pure public sector provision and financing, expansion of PPPs could reduce government financing required per TB patient treated from $609–690 to $130–139 in PNP and $36–46 in PWP. Conclusion There is a strong economic case for expanding PPP in TB treatment and potentially for other types of health services. Where PPPs are tailored to target groups and supported by the public sector, scaling up of effective services could occur at much lower cost than solely relying on public sector models.

    Headaches affect 90% of the population sometime during their life. Most are benign and fleeting, some are serious and life-threatening, and others require ongoing medical consultation and treatment. A careful history and physical is necessary to establish a differential diagnosis and to guide the choice of testing to make an accurate diagnosis. The most common types of headaches are discussed in this review. They are divided into primary and secondary headache disorders as classified by the International Headache Society. Primary headache disorders include migraine without and with aura, cluster and tension-type headaches. Secondary headaches are those that occur as a result of some other disorder and include brain tumors, rhinosinusitis, diseases of intracranial and extracranial vasculature, and temporomandibular joint disease.

    Time diaries of sibling pairs from the PSID-CDS are used to determine whether maternal time investments compensate for or reinforce birth-weight differences among children. The findings demonstrate that the direction and degree of differential treatment vary by mother's education. Less-educated mothers devote more total time and more educationally oriented time to heavier-birth-weight children, whereas better-educated mothers devote more total and more educationally oriented time to lower-birth-weight children. The compensating effects observed among highly educated mothers are substantially larger than the reinforcing effects among the least-educated mothers. The findings show that families redistribute resources in ways that both compensate for and exacerbate early-life disadvantages. PMID:22865101

    Herndon, C.D. Anthony

    2006-01-01

    The diagnosis, evaluation and management of antenatal hydronephrosis has undergone a two stage paradigm shift since the advent of prenatal ultrasonography in the early 1980s. Initially the identification of a large number of asymptomatic infants appeared to afford the surgeon the opportunity for preemptive intervention. However, it has now become apparent that antenatal hydronephrosis (AH) is far more difficult to interpret thanoriginally perceived. The initial enthusiasm for surgery has now been replaced by a much more conservative approach to ureteropelvic junction(UPJ) obstruction, multi-cystic dysplastic kidney(MCDK), vesicoureteral reflux and the non-refluxing megaureter. This review will highlight the postnatal evaluation of AH and include an overview of the Society for Fetal Urology grading system for hydronephrosis. The differential diagnosis and treatment options for UPJ obstruction, vesicoureteral reflux, MCDK, duplication anomalies, megaureter, and posterior urethral valves will be discussed. PMID:17619702

  11. Dark or short nights: differential latitudinal constraints in nestling provisioning patterns of a nocturnally hunting bird species.

    Directory of Open Access Journals (Sweden)

    Markéta Zárybnická

    Full Text Available In diurnal bird species, individuals breeding at high latitudes have larger broods than at lower latitudes, which has been linked to differences in the daily time available for foraging. However, it remains unclear how latitude is linked with parental investment in nocturnal species. Here, we investigate nestling provisioning rates of male Tengmalm's owls in two populations at different latitudes (Czech Republic 50 °N; Finland 63 °N with the help of cameras integrated into nest boxes. Clutch sizes were smaller in the Czech population (CZ: 5.1 ± 0.1; FIN: 6.6 ± 0.1, but given the higher nestling mortality in the Finnish population, the number of fledglings did not differ between the two populations (CZ: 3.5 ± 0.3; FIN: 3.9 ± 0.2. Nestling provisioning patterns varied within days, over the reproductive season and between the two sites. Males delivered most food at dusk and dawn, having peak delivery rates at sun angles of -11° to -15° at both sites, and males increased the prey delivery rates with higher nestling requirements. Given the longer nights during summer in the Czech Republic compared to Finland, Czech males only showed a small shift in their delivery peak during the night from -17° in April to -14° in July. In contrast, Finnish males shifted their peak of prey delivery from -11° in April to -1° in July. Consequently, Czech males had a longer hunting time per night around midsummer when feeding young (360 min than Finnish males (270 min. This suggests that nocturnal owl species in northern populations are constrained by the short nights during the breeding season, which can limit the number of young they can raise. Moreover, owls in northern populations are additionally constrained through the unpredictable changes in food availability between years, and both these factors are likely to influence the reproductive investment between populations.

    Climate change has been felt to take place in Indonesia, causing the temperature to increase, additional drought with more moisture evaporates from rivers, lakes, and other bodies of water, and intense rainfall in a shorter rainy season. One of the major concerns is the risk of severe drought leading to water shortages. It will affect water supply and agriculture yields. As a country extremely vulnerable to the climate change, Indonesia must adapt to the serious environmental issues. This paper aims to offer an effort of water provision by recycling and reusing of greywater applying constructed wetland systems. The treated greywater is useful as water provision for non-consumptive uses. A recent experiment was conducted on a household yard using a single horizontal subsurface flow type of constructed wetland. The experiments demonstrated that the constructed wetland systems reduced effectively the pollutants of TSS, BOD, COD, and detergent to the level that are compliant with regulatory standards. The constructed wetland has been established for almost two years however the system still works properly.

    The ingestion of plastic by seabirds has been used as an indicator of population and ocean health. However, few studies have examined adults and juveniles of the same species concurrent with the availability of plastic in the local marine environment. In King George Sound (KGS), Western Australia, 13% of adult flesh-footed shearwaters (Ardenna carneipes) and 90% of fledglings contained plastic items in their digestive tract. On Lord Howe Island (LHI), New South Wales, 75% of adult shearwaters and 100% of fledglings contained plastic. Ingested items were assessed using Jaccard's Index (where J = 0 indicates complete dissimilarity and J = 1 complete similarity). The colour of items ingested by self- and chick-provisioning shearwaters from KGS exhibited broad overlap with plastic available in the local environment (J = 0.78-0.80), and plastic in adults and fledglings from LHI were less similar to those available (J = 0.31-0.58). Additional data on seabird colour selection would improve our understanding of the factors influencing the behaviour of ingesting plastic, and its contribution to the decline of some species.

    Despite clinical practice guidelines recommending the routine provision of nicotine dependence treatment to smokers in inpatient psychiatric facilities, the prevalence of such treatment provision is low. The aim of this study was to examine the effectiveness of a clinical practice change intervention in increasing clinician recorded provision of nicotine dependence treatment to patients in inpatient psychiatric facilities. We undertook an interrupted time series analysis of nicotine dependence treatment provision before, during and after a clinical practice change intervention to increase clinician recorded provision of nicotine dependence treatment for all hospital discharges (aged >18 years, N = 4175) over a 19 month period in two inpatient adult psychiatric facilities in New South Wales, Australia. The clinical practice change intervention comprised six key strategies: leadership and consensus, enabling systems and procedures, training and education, information and resources, audit and feedback and an on-site practice change support officer. Systematic medical record audit and segmented logistic regression was used to determine differences in proportions for each nicotine dependence treatment outcome measure between the 'pre', 'during' and 'post-intervention' periods. The prevalence of all five outcome measures increased significantly between the pre and post-intervention periods, including clinician recorded: assessment of patient smoking status (36.43 to 51.95%; adjusted odds ratio [AOR] = 2.39, 99% Confidence Interval [CI]: 1.23 to 4.66); assessment of patient nicotine dependence status (4.74 to 11.04%; AOR = 109.67, 99% CI: 35.35 to 340.22); provision of brief advice to quit (0.85 to 8.81%; AOR = 97.43, 99% CI: 31.03 to 306.30); provision of nicotine replacement therapy (8.06 to 26.25%; AOR = 19.59, 99% CI: 8.17 to 46.94); and provision of nicotine dependence treatment on discharge (8.82 to 13.45%, AOR = 12.36; 99% CI: 6.08 to 25

    2007-01-01

    Full text: Well-differentiated thyroid cancer (DTCA) in children is quite different from the adult- onset disease in that they are more aggressive at the time of diagnosis and with metastases and has a higher risk for recurrence. Some studies claim it to be less lethal and hence treatment protocols may be different from that of the adult. This study was made to analyze the need for RAI therapy as one of the cornerstone of treatment aside from surgery and thyroid hormone suppression as well as to determine the behavior of WDTCA in children. Results: The incidence of DTCA is varied and ranges from 1-10% in several published series. In the Philippines where thyroid cancer in adults ranks 5th in mortality for both sexes, the incidence is likewise very low, around 0.5-1% for ages 18 years and below in a ten year study. It was predominantly a female population (74%) as compared to the males (26%). Fifteen cases were reviewed and included as most were given RAI (87%). Most presented as a solitary nodule and with lymph node metastases. Thirteen cases were papillary in nature and only two cases were follicular. The incidence of nodal metastases was 53% while lung metastases were seen in 20% of cases. Of the 13 cases that underwent RAI therapy, three cases of lung metastases needed repeat therapy. In the cases with lymph node metastases, 2 cases also had recurrence and which necessitated repeat RAI therapy. The two cases that did not get RAI therapy had progressive disease on follow- up after 5 and 7 years respectively from surgery. Discussion: Primary treatment for DTC should consist of surgery, radioiodine ablation and thyroid hormone suppression. We must rely on pediatric outcome studies and the high frequency of multifocal intrathyroidal disease, loco- regional spread and extra cervical metastases often seen as initial presentations of this particular group. The more advanced disease at diagnosis for children, propensity for recurrence as well as the greater radioiodine

    Patient adherence to psychosocial treatment is an important but understudied topic. The aim of this study was to examine whether better patient recall of treatment contents and therapist use of memory support (MS) were associated with better treatment adherence. Data were drawn from a pilot randomized controlled trial. Participants were 48 individuals (mean age = 44.27 years, 29 females) with Major Depressive Disorder randomized to receive either Cognitive Therapy (CT) with an adjunctive Memory Support Intervention (CT + Memory Support) or CT-as-usual. Therapist and patient ratings of treatment adherence were collected during each treatment session. Patient recall was assessed at mid-treatment. Therapist use of MS was manually coded for a random selection of sessions. Patient recall was significantly associated with better therapist and patient ratings of adherence. Therapist use of Application, a specific MS strategy, predicted higher therapist ratings of adherence. Attention Recruitment, another specific MS strategy, appeared to attenuate the positive impact of session number on patient ratings of adherence. Treatment groups, MS summary scores and other specific MS strategies were not significantly associated with adherence. The measure for treatment adherence is in the process of being formally validated. Results were based on small sample. These results support the importance of patient recall in treatment adherence. Although collectively the effects of MS on treatment adherence were not significant, the results support the use of certain specific MS strategy (i.e., application) as a potential pathway to improve treatment adherence. Larger-scale studies are needed to further examine these constructs. Copyright © 2016 Elsevier Ltd. All rights reserved.

  19. Directed funding to address under-provision of treatment for substance use disorders: a quantitative study.

    Substance use disorders (SUDs) are a substantial problem in the United States (U.S.), affecting far more people than receive treatment. This is true broadly and within the U.S. military veteran population, which is our focus. To increase funding for treatment, the Veterans Health Administration (VA) has implemented several initiatives over the past decade to direct funds toward SUD treatment, supplementing the unrestricted funds VA medical centers receive. We study the 'flypaper effect' or the extent to which these directed funds have actually increased SUD treatment spending. The study sample included all VA facilities and used observational data spanning years 2002 to 2010. Data were analyzed with a fixed effects, ordinary least squares specification with monetized workload as the dependent variable and funding dedicated to SUD specialty clinics the key dependent variable, controlling for unrestricted funding. We observed different effects of dedicated SUD specialty clinic funding over the period 2002 to 2008 versus 2009 to 2010. In the earlier period, there is no evidence of a significant portion of the dedicated funding sticking to its target. In the later period, a substantial proportion--38% in 2009 and 61% in 2010--of funding dedicated to SUD specialty clinics did translate into increased medical center spending for SUD treatment. In comparison, only five cents of every dollar of unrestricted funding is spent on SUD treatment. Relative to unrestricted funding, dedicated funding for SUD treatment was much more effective in increasing workload, but only in years 2009 and 2010. The differences in those years relative to prior ones may be due to the observed management focus on SUD and SUD-related treatment in the later years. If true, this suggests that in a centrally directed healthcare organization such as the VA, funding dedicated to a service is a necessary, but not sufficient condition for increasing resources expended for that service.

    Full Text Available Aim: The aim of the study was to that assess the perceptions and understanding of dental practitioners in the provision of dental treatment to pregnant women. Materials and Methods: The study was a quantitative, cross-sectional type. A sample size of 200 dental practitioners were included in the study between the period of 6 months, i.e. June–December. A cluster sampling technique was employed covering four different dental institutes. A structured questionnaire was designed to assess the perception and understanding of dental practitioners in providing treatment to the pregnant women. Statistical Analysis: Statistical analysis was performed using SPSS version 19. Chi-square test was done to analyze the association of perception of dental practitioners in treating pregnant women in relation to gender. Results: A total of 200 dental practitioners filled the questionnaire out of which 43% (86 were males and 57% (114 were females. Eighty-two percent of the total participants said that it is safe to provide dental treatment during pregnancy, almost 90.4% of the total dentist interviewed was aware of the special position in which to place a pregnant woman on a dental chair. 85.5% of the study population do not prefer taking radiographs of a pregnant woman, 63% of the entire dentist surveyed prefers to use local anesthesia before any dental procedure on a pregnant patient. 96.5% care to educate their pregnant patient about improving dental health care. 59.5% of the dental practitioners said that they would consult the patient's gynecologist as a mandatory requirement before treating the patient. 57% of the dental practitioners answered with gingivitis. 70.5% agreed on scaling. The majority of the dentists prescribed paracetamol 85.5%. Conclusion: Little is known about the perception and utilization of dental practitioners in providing dental treatment to pregnant women in Pakistan. The present survey concluded that dental practitioners lack

  1. The politics of place(ment): problematising the provision of hepatitis C treatment within opiate substitution clinics.

    The hepatitis C virus (HCV) epidemic is a significant public health challenge in Australia. Current initiatives to expand access to HCV treatment focus on opiate substitution therapy (OST) settings where the prevalence of hepatitis C among clients is high. In Australia, the provision of OST for many clients is via large clinics, with an estimated median of 150 clients per service. Conceptually informed by the work of Michel Foucault, our analysis of the proposed integrated treatment model focuses on the critical but overlooked question of organisational culture and power operating within OST. We argue that the specific context of OST not merely reflects but actively participates in the political economy of social exclusion via which the socio-spatial segregation and stigmatisation of the service user as 'drug user' is enacted. This paper analyses data collected from two samples during 2008/9: OST clients living in New South Wales, Australia and a range of OST health professionals working in Australian settings. In total, 27 interviews were conducted with current OST clients; 19 by phone and 8 face-to-face. One focus group and 16 telephone interviews were conducted with OST health professionals. Our analysis of key themes emerging from the interview data suggests that the successful introduction of HCV treatment within the OST clinic is not a given. We are concerned that particular areas of tension, if not explicit contradiction, have been overlooked in current research and debates informing the proposed combination treatment model. We question the appropriateness of co-locating a notoriously arduous, exacting treatment (HCV) within the highly surveillant and regulatory environment of OST. While applauding the intention to improve access to HCV care and treatment for people who inject drugs we caution against a treatment model that risks further entrenching (socio-spatial) stigmatisation amongst those already experiencing significant marginalisation.

    Past work highlights that parents' differential treatment has implications for offspring's mental and relational health across the life course. Although the current body of literature has examined offspring- and parent-level correlates of differential treatment, research has yet to consider whether and how patterns of differential treatment are transmitted across generations. As part of a two-wave longitudinal study of 157 families, both grandparents (M age = 76.50 years, SD = 6.20) and parents (M age = 51.10 years, SD = 4.41) reported on differential treatment of their own offspring at both phases. A series of residualized change models revealed support for both continuity and compensation hypotheses. Middle-aged parents tended to model the patterns of differential treatment exhibited by their fathers, but middle-aged men who experienced more differential treatment from their own parents in recent years tended to subsequently exhibit lower levels of differential treatment to their offspring. These findings suggest that patterns of differential treatment both continue and diverge across generations, and those patterns vary by gender. On a broader level, these results also suggest that siblings not only impact one another's development, but in adulthood, they may indirectly influence their nieces' and nephews' development by virtue of their influence on their siblings' parenting. © The Author 2016.

    Full Text Available Abstract Background Crisis resolution and home treatment (CRHT is an emerging mode of delivering acute mental health care in the community. There is a paucity of knowledge regarding the workings of CRHT in the literature. This is the second paper in a series of three from the longitudinal survey of patients of a CRHT team in Norway, which was aimed at describing the characteristics of patients served, professional services provided, and clinical outcomes. This report focuses on the provision of professional services by the team. Methods The project was a descriptive, quantitative study based on the patient data from a longitudinal survey of one CRHT team in Norway. The participants of the survey, a total of 363 patients, constituted the complete registration of patients of this team in the period from February 2008 to July 2009. Results The average length of service by the team was about 15 days, and those with depression as the major symptom had the longest mean length of stay on the team. The team was engaged in providing a variety of services including individual treatments involving multiple professionals, group treatment meetings, and coordination activities involving external service sectors. While the type of professionals providing individual treatment was not associated with the severity level of clinical problems, those receiving various group treatment meetings had more serious level of clinical symptoms than those not receiving group treatment meetings. In addition coordination activities involving healthcare professionals and social services in the community were in line with the patients' clinical and social needs. The results of the study show that the team functioned effectively in addressing the general guidelines for the functioning of CRHT teams.

    Approximately 600 million people lack access to safe drinking water, hence achieving Sustainable Development Goal 6 (Ensure availability and sustainable management of water and sanitation for all by 2030) calls for rapid translation of recent research into practical and frugal solutions within the remaining 13 years. Biochars, with excellent capacity to remove several contaminants from aqueous solutions, constitute an untapped technology for drinking water treatment. Biochar water treatment has several potential merits compared to existing low-cost methods (i.e., sand filtration, boiling, solar disinfection, chlorination): (1) biochar is a low-cost and renewable adsorbent made using readily available biomaterials and skills, making it appropriate for low-income communities; (2) existing methods predominantly remove pathogens, but biochars remove chemical, biological and physical contaminants; (3) biochars maintain organoleptic properties of water, while existing methods generate carcinogenic by-products (e.g., chlorination) and/or increase concentrations of chemical contaminants (e.g., boiling). Biochars have co-benefits including provision of clean energy for household heating and cooking, and soil application of spent biochar improves soil quality and crop yields. Integrating biochar into the water and sanitation system transforms linear material flows into looped material cycles, consistent with terra preta sanitation. Lack of design information on biochar water treatment, and environmental and public health risks constrain the biochar technology. Seven hypotheses for future research are highlighted under three themes: (1) design and optimization of biochar water treatment; (2) ecotoxicology and human health risks associated with contaminant transfer along the biochar-soil-food-human pathway, and (3) life cycle analyses of carbon and energy footprints of biochar water treatment systems.

    Full Text Available Abstract Background Improvement of utilization of malaria treatment services will depend on provision of treatment services that different population groups of consumers prefer and would want to use. Treatment of malaria in Nigeria is still problematic and this contributes to worsening burden of the disease in the country. Therefore this study explores the socio-economic and geographic differences in consumers' preferences for improved treatment of malaria in Southeast Nigeria and how the results can be used to improve the deployment of malaria treatment services. Methods This study was undertaken in Anambra state, Southeast Nigeria in three rural and three urban areas. A total of 2,250 randomly selected householders were interviewed using a pre tested interviewer administered questionnaire. Preferences were elicited using both a rating scale and ranking of different treatment provision sources by the respondents. A socio-economic status (SES index was used to examine for SES differences, whilst urban-rural comparison was used to examine for geographic differences, in preferences. Results The most preferred source of provision of malaria treatment services was public hospitals (30.5%, training of mothers (19% and treatment in Primary healthcare centres (18.1%. Traditional healers (4.8% and patent medicine dealers (4.2% were the least preferred strategies for improving malaria treatment. Some of the preferences differed by SES and by a lesser extent, the geographic location of the respondents. Conclusion Preferences for provision of improved malaria treatment services were influenced by SES and by geographic location. There should be re-invigoration of public facilities for appropriate diagnosis and treatment of malaria, in addition to improving the financial and geographic accessibility of such facilities. Training of mothers should be encouraged but home management will not work if the quality of services of patent medicine dealers and pharmacy

    2016-01-01

    Background Online technologies may reduce barriers to evidence-based mental health care, yet they also create numerous ethical challenges. Recently, numerous professional organizations and expert groups have produced best-practice guidelines to assist mental health professionals in delivering online interventions in an ethically and clinically sound manner. However, there has been little critical examination of these international best-practice guidelines regarding appropriate electronic mental health (e-mental health) service delivery via technologies such as videoconferencing (including Skype), particularly for specific, vulnerable populations. Further, the extent to which concordance exists between these guidelines remains unclear. Synthesizing this literature to provide clear guidance to both mental health professionals and researchers is critical to ensure continued progress in the field of e-mental health. Objective This study aims to review all currently available ethical and best-practice guidelines relating to videoconferencing-delivered mental health treatments in order to ascertain the recommendations for which international consensus could be found. Additionally, this review examines the extent to which each set of guidance addresses several key special populations, including children and young people, and populations living with illness. Methods This systematic review examined guidelines using a two-armed search strategy, examining (1) professional organizations’ published guidance; and (2) MEDLINE, PsycINFO, and EMBASE for the past ten years. In order to determine consensus for best-practice, a recommendation was considered "firm" if 50% or more of the reviewed guidelines endorsed it and "tentative" if recommended by fewer guidelines than these. The professional guidelines were also scored by two raters using the Appraisal of Guidelines for Research and Evaluation II (AGREE-II) criteria. Results In the study, 19 guidelines were included, yielding 11

Cross-sectional study. Online survey from December 2014 to July 2015. Contacts in 172 countries were surveyed, representing 169 of the 180 FCTC Parties at the time of the survey. A 26-item questionnaire based on the Article 14 recommendations including tobacco treatment infrastructure and cessation support systems. Progress over time was assessed for those countries that also participated in our 2012 survey and did not change country income level classification. We received responses from contacts in 142 countries, an 83% response rate. Overall, 54% of respondents reported that their country had an officially identified person responsible for tobacco dependence treatment, 32% an official national treatment strategy, 40% official national treatment guidelines, 25% a clearly identified budget for treatment, 17% text messaging, 23% free national quitlines and 26% specialized treatment services. Most measures were associated positively and significantly with countries' income level (P Article 14 and its guidelines, and for most measures, provision was greater the higher the country's income. There was little improvement in treatment provision between 2012 and 2015 in all countries. © 2017 The Authors.

    To review the results of five research projects commissioned to enhance alcohol treatment among Aboriginal Australians, and to highlight arising from them. Drafts of the papers were workshopped by project representatives, final papers reviewed and results summarised. Lessons arising were identified and described. While the impact of the projects varied, they highlight the feasibility of adapting mainstream interventions in Aboriginal Australian contexts. Outcomes include greater potential to: screen for those at risk; increase community awareness; build capacity and partnerships between organisations; and co-ordinate comprehensive referral networks and service provision. Results show a small investment can produce sustainable change and positive outcomes. However, to optimise and maintain investment, cultural difference needs to be recognised in both planning and delivery of alcohol interventions; resources and funding must be responsive to and realistic about the capacities of organisations; partnerships need to be formed voluntarily based on respect, equality and trust; and practices and procedures within organisations need to be formalised. There is no simple way to reduce alcohol-related harm in Aboriginal communities. However, the papers reviewed show that with Aboriginal control, modest investment and respectful collaboration, service enhancements and improved outcomes can be achieved. Mainstream interventions need to be adapted to Aboriginal settings, not simply transferred. The lessons outlined provide important reflections for future research. © 2014 Australasian Professional Society on Alcohol and other Drugs.

  11. Explaining the differences in household food waste collection and treatment provisions between local authorities in England and Wales.

    2017-12-01

    Separate household food waste collection for anaerobic digestion is one method used in the sustainable management of biodegradable municipal solid waste (MSW). Recycling of food waste contributes to the UK's reuse, recycling and composting targets and can help local authorities boost plateauing rates whilst encouraging landfill diversion. This study explored the reasons for differences in the provision of food waste collections, using two comparable local authorities, one with a collection in Wales (Cardiff), and the other absent of such service in England (Southampton). A PESTLE analysis investigated the political, economic, social, technological, legal and environmental impacts of separate food waste collections. The greenhouse gas impacts of the collection and treatment systems of MSW in both cities were estimated for 2012/13. Results showed significant policy and legislative differences between devolved governments, that separate food waste collections can save local authorities significant sums of money and substantially reduce greenhouse gas impacts. A survey of one hundred respondents in each city aimed to understand attitudes and behaviours towards recycling, food waste segregation, cooking and purchasing habits. The number of frequent recyclers and levels of satisfaction were higher in the authority which provided a separate food waste collection. In the area which lacked a separate collection service, over three-quarters of respondents would participate in such a scheme if it were available. Copyright © 2017 Elsevier Ltd.

    Parents' differential treatment (PDT) is a common family dynamic that has been linked to youth development and well-being, including adjustment problems and poor sibling relationships. Much less is known, however, about the developmental course of PDT and the conditions under which parents treat their children differently in adolescence and young adulthood. This study examined longitudinal changes in mothers' and fathers' differential warmth and conflict with their two offspring from early adolescence through young adulthood and examined parents' experiences of individual stress (depressive symptoms and role overload) and marital difficulties as time-varying correlates of (changes in) PDT. We also tested crossover effects to determine whether mothers' experiences of individual stress and marital difficulties were linked to fathers' differential treatment, and vice versa. Participants were mothers, fathers, and two siblings from 246 Mexican-origin families who were interviewed in their homes on three occasions over 8 years. Multilevel models revealed that mothers' and fathers' differential conflict with their two children increased until middle adolescence and then declined into young adulthood, but there were no changes over time for parents' differential warmth. In general, both mothers' and fathers' levels of differential treatment were exacerbated by their own experiences of individual stress and marital difficulties and also by the experiences of their spouses. However, in some cases, greater stress than usual was linked to less differential treatment than usual. © 2017 Family Process Institute.

    To study causes of vertigo in hypertensive patients and specify approaches to its treatment. Material and methods. Prevalence and causes of vertigo were analysed in 285 patients with arterial hypertension (AH). The examination included 24-h monitoring of arterial pressure (APM) and MR-tomography of the head. The majority of patients (78%) hospitalized with the diagnosis "hypertensive crisis" were diagnosed to have other diseases (headaches of tension, stroke, Meniere's syndrome and disease, etc.) the development of which was accompanied with hypertension and simulated a hypertensive crisis. Vertigo occurs in 20% hypertensive patients and is unrelated to elevated blood pressure. It is rather due to associated neurological, peripheral vestibular and other diseases. APM shows that vertigo occurs in hypotension after intake of hypotensive drugs. In hypertensive patients treatment of vertigo should not be directed only to management of elevated pressure but demands treatment of underlying disease. Vertigo plus mnestic disorders are effectively corrected with tanakan in a dose 120-160 mg/day. Vertigo in hypertensive patients is not caused by elevated pressure but related with concomitant neurological or peripheral vestibular diseases as well as hypotension. Hypertensive patients with vertigo need correction of the condition causing it.

Status epilepticus is a neurologic emergency and requires prompt intervention to minimize morbidity and mortality. Treatment involves both supportive care as well as initiation of medications to stop all clinical and electrographic seizure activity. Benzodiazepines are used as first-line agents, followed by antiepileptic drugs when seizures persist. In refractory status epilepticus, urgent neurologic consultation is indicated for the titration of anesthetic agents to a level of appropriate background suppression on EEG. In light of our aging population, physician awareness and competence in the management of status epilepticus is imperative and should be recognized as a growing public health concern.Keywords: status epilepticus, convulsive, generalized, nonconvulsive, refractory, elderly, treatment

    Selective laser melting (SLM) technology is useful for the fabrication of porous titanium implants with complex shapes and structures. The materials fabricated by SLM characteristically have a very rough surface (average surface roughness, Ra=24.58 µm). In this study, we evaluated morphologically and biochemically the specific effects of this very rough surface and the additional effects of a bioactive treatment on osteoblast proliferation and differentiation. Flat-rolled titanium materials (Ra=1.02 µm) were used as the controls. On the treated materials fabricated by SLM, we observed enhanced osteoblast differentiation compared with the flat-rolled materials and the untreated materials fabricated by SLM. No significant differences were observed between the flat-rolled materials and the untreated materials fabricated by SLM in their effects on osteoblast differentiation. We concluded that the very rough surface fabricated by SLM had to undergo a bioactive treatment to obtain a positive effect on osteoblast differentiation.

    Maxwell’s equations are derived in terms of differential forms in the four-dimensional Minkowski representation, starting from the three-dimensional vector calculus differential version of these equations. Introducing all the mathematical and physical concepts needed (including the tool of differential forms), using only knowledge of elementary vector calculus and the local vector version of Maxwell’s equations, the equations are reduced to a simple and elegant set of two equations for a unified quantity, the electromagnetic field. The treatment should be accessible for students taking a first course on electromagnetism.

    The Mental Health (Care and Treatment) (Scotland) Act 2003 introduced the role of the Named Person, who can be nominated by service users to protect their interests if they become subject to compulsory measures and replaces the Nearest Relative. If no nomination is made, the primary carer or nearest relative is appointed the Named Person. The views of professionals involved in the development and implementation of the provisions were unknown. To describe the perceptions of mental health officers and policy makers involved in the development and implementation of the new provisions. Sixteen professionals were interviewed to explore their perceptions of and experiences with the Named Person provisions. Data were analysed using Thematic Analysis. Perceptions of the Named Person provisions were generally favourable but concerns were expressed over low uptake; service users' and carers' lack of understanding of the role; and potential conflict with human rights legislation over choice and information sharing. Legislation should be amended to allow the choice of no Named Person and the prevention of information being shared with the default appointed Named Person. Removal of the default appointment should be considered.

    2013-01-01

    Due diligence in the process of provision of healthcare services refers, among other elements, to the application of pharmacological therapy at a time which offers the greatest chance for a successful outcome of treatment, i.e. for achieving the optimum expected effect understood as an improvement in the patient's health, reduction of health risks or elimination of the disease. However, due diligence may also refer to actions aimed at ensuring that neither the patient nor the healthcare payer is required to incur unreasonable costs in the process of treatment. The validity of that statement stems not only from normative acts but also from ethical standards laid down in the Medical Code of Ethics (Article 57 section 2). It often happens that the provision of optimal treatment calls for deviations from the formal provisions included in Summary Product Characteristics (SPCs), and the application of drugs that are bioequivalent to reference drugs, which translates into a significant reduction of costs. The present study addresses the problem of acceptability of a specific form of drug substitution consisting in the replacement of a reference drug with a generic drug. Also explored are legal aspects associated with the possibility of therapy based on “off-label use”. The study reviews normative acts existing in the Polish and EU legislation. It also provides a clear definition of orphan drug, which has made it possible to make a distinction and investigate mutual relations between the concepts of brand-name (reference) drug, orphan drug and generic drug.

    2013-01-01

    This study examined within-family stability in parents’ differential treatment of siblings from adolescence to young adulthood and the effect of differential treatment in young adulthood on grown siblings’ relationship quality. The author used longitudinal data on parent – child and sibling relations from the sibling sample of the National Longitudinal Study of Adolescent Health (N = 1,470 sibling dyads). Within-dyad fixed effects regression models revealed that the adolescent sibling who was closer to parents went on to be the young adult sibling who was closer to and received more material support from parents. Results from an actor – partner interdependence model revealed that differential parental financial assistance of young adult siblings predicted worse sibling relationship quality. These findings demonstrate the lasting importance of affect between parents and offspring earlier in the family life course and the relevance of within-family inequalities for understanding family relations.

    The optimum dose for the differentiated thyroid cancer treatment is a motive of controversy. There exist two ways of deciding the dose to administer: the empirical method (fixed doses) and dosimetric calculation method. The use of fixed doses has demonstrated safety and effectiveness. Nevertheless there are cases in which the use of several small doses not resolves the metastases illness of the patients. Using the Benua-Leeper method for dosimetric calculation we have evaluated the maximum dose treatment that could be administered to 20 patients who showed persistent disease after several treatments with 131 I.

    Cigarette smoking is common among patients in substance abuse treatment. Tobacco control programs have advocated for integrated tobacco dependence treatment into behavioral healthcare, including within substance abuse treatment facilities (SATFs) to reduce the public health burden of tobacco use. This study used data from seven waves (2006 to 2012) of the National Survey of Substance Abuse Treatment Services (n=94,145) to examine state and annual changes in the provision of smoking cessation services within US SATFs and whether changes over time could be explained by facility-level (private vs public ownership, receipt of earmarks, facility admissions, acceptance of government insurance) and state-level factors (cigarette tax per pack, smoke free policies, and percent of CDC recommended tobacco prevention spending). Results showed that the prevalence of SATFs offering smoking cessation services increased over time, from 13% to 65%. The amount of tax per cigarette pack, accepting government insurance, government (vs private) ownership, facility admissions, and CDC recommended tobacco prevention spending (per state) were the strongest correlates of the provision of smoking cessation programs in SATFs. Facilities that received earmarks were less likely to provide cessation services. Adult smoking prevalence and state-level smoke free policies were not significant correlates of the provision of smoking cessation services over time. Policies aimed at increasing the distribution of tax revenues to cessation services in SATFs may offset tobacco-related burden among those with substance abuse problems. Copyright © 2017.

    Since the pioneering work of Salmon and Durie, quantitative measures of tumor burden in multiple myeloma have been used to make clinical predictions and model tumor growth. However, such quantitative analyses have not yet been performed on large datasets from trials using modern chemotherapy regimens. We analyzed a large set of tumor response data from three randomized controlled trials of bortezomib-based chemotherapy regimens (total sample size n = 1,469 patients) to establish and validate a novel mathematical model of multiple myeloma cell dynamics. Treatment dynamics in newly diagnosed patients were most consistent with a model postulating two tumor cell subpopulations, "progenitor cells" and "differentiated cells." Differential treatment responses were observed with significant tumoricidal effects on differentiated cells and less clear effects on progenitor cells. We validated this model using a second trial of newly diagnosed patients and a third trial of refractory patients. When applying our model to data of relapsed patients, we found that a hybrid model incorporating both a differentiation hierarchy and clonal evolution best explains the response patterns. The clinical data, together with mathematical modeling, suggest that bortezomib-based therapy exerts a selection pressure on myeloma cells that can shape the disease phenotype, thereby generating further inter-patient variability. This model may be a useful tool for improving our understanding of disease biology and the response to chemotherapy regimens.

    Growth mixture modeling (GMM) identified latent groups based on treatment outcome trajectories of headache disability measures in patients in headache subspecialty treatment clinics. Using a longitudinal design, 219 patients in headache subspecialty clinics in 4 large cities throughout Ohio provided data on their headache disability at pretreatment and 3 follow-up assessments. GMM identified 3 treatment outcome trajectory groups: (1) patients who initiated treatment with elevated disability levels and who reported statistically significant reductions in headache disability (high-disability improvers; 11%); (2) patients who initiated treatment with elevated disability but who reported no reductions in disability (high-disability nonimprovers; 34%); and (3) patients who initiated treatment with moderate disability and who reported statistically significant reductions in headache disability (moderate-disability improvers; 55%). Based on the final multinomial logistic regression model, a dichotomized treatment appointment attendance variable was a statistically significant predictor for differentiating high-disability improvers from high-disability nonimprovers. Three-fourths of patients who initiated treatment with elevated disability levels did not report reductions in disability after 5 months of treatment with new preventive pharmacotherapies. Preventive headache agents may be most efficacious for patients with moderate levels of disability and for patients with high disability levels who attend all treatment appointments.

    This study examined associations between changes in sibling relationships and changes in parental differential treatment and corresponding changes in children's adjustment. One hundred thirty-three families were assessed at 3 time points. Parents rated children's externalizing problems, and children reported on sibling relationship quality, parental differential treatment, and depressive symptoms. On average, older siblings were 10, 12, and 16 years old, and younger siblings were 8, 10, and 14 years old at Waves 1, 2, and 3, respectively. Results from hierarchical linear modeling indicated that as sibling relationships improved over time, children's depressive symptoms decreased over time. In addition, as children were less favored over their siblings over time, children's externalizing problems increased over time. Findings highlight the developmental interplay between the sibling context and children's adjustment. Copyright 2006 APA, all rights reserved).

This paper aims to evaluate the influence of physician to personalized medicine in the process of TBSD. Methods. We performed a randomized, triple-blind trial involving patients of primary insomnia treated by 3 physicians individually and independently. The patients (n=30 were randomly assigned to receive treatments by the 3 physicians for every visit. However, they always received the treatment, respectively, prescribed by the physician at the first visit. The primary outcome was evaluated, respectively, by the Pittsburgh Sleep Quality Index (PSQI and the TCM symptoms measuring scale. The clinical practices of the physicians were recorded at every visit including diagnostic information, syndrome differentiation, treating principles, and prescriptions. Results. All patients in the 3 groups (30 patients showed significant improvements (>66% according to the PSQI and TCM symptoms measuring scale. Conclusion. The results indicate that although with comparable effectiveness, there exist significant differences in syndrome differentiation, the treating principles, and the prescriptions of the approaches used by the 3 physicians. This means that the physician should be considered as an important factor for individualized medicine and the related TCM clinical research.

    Osteopontin is a marker for breast cancer progression, which in previous studies has also been associated with resistance to certain anti-cancer therapies. It is not known which splice variants may mediate treatment resistance. Here we analyze the association of osteopontin variant expression before treatment, differentiated according to immunohistochemistry with antibodies to exon 4 and to the osteopontin-c splice junction respectively, with the ensuing therapy responses in 119 Polish breast cancer patients who presented between 1995 and 2008. We found from Cox hazard models, logrank test and Wilcoxon test that osteopontin exon 4 was associated with a favorable response to tamoxifen, but a poor response to chemotherapy with CMF (cyclophosphamide, methotrexate, fluorouracil). Osteopontin-c is prognostic, but falls short of being a significant predictor for sensitivity to treatment. The addition of osteopontin splice variant immunohistochemistry to standard pathology work-ups has the potential to aid decision making in breast cancer treatment.

    In this study, we investigated whether nitric oxide (NO) generated using a non-thermal plasma system can mediate osteoblastic differentiation of osteoprogenitor cells without creating toxicity. Our objective was to create an NO delivery mechanism using NO-dielectric barrier discharge (DBD) plasma that can generate and transport NO with controlled concentration to the area of interest to regulate osteoprogenitor cell activity. We built a non-thermal atmospheric pressure DBD plasma nozzle system based on our previously published design and similar designs in the literature. The electrical and spectral analyses demonstrated that N 2 dissociated into NO under typical DBD voltage–current characteristics. We treated osteoprogenitor cells (MC3T3-E1) using NO-plasma treatment system. Our results demonstrated that we could control NO concentration within cell culture media and could introduce NO into the intracellular space using NO-plasma treatment with various treatment times. We confirmed that NO-plasma treatment maintained cell viability and did not create any toxicity even with prolonged treatment durations. Finally, we demonstrated that NO-plasma treatment induced early osteogenic differentiation in the absence of pro-osteogenic growth factors/proteins. These findings suggest that through the NO-plasma treatment system we are able to generate and transport tissue-specific amounts of NO to an area of interest to mediate osteoprogenitor cell activity without subsequent toxicity. This opens up the possibility to develop DBD plasma-assisted tissue-specific NO delivery strategies for therapeutic intervention in the prevention and treatment of bone diseases. (paper)

Although the direct relations between PDT and youth's maladjustment have been well established, the mechanisms underlying these associations remain unclear. We addressed this gap by examining whether sibling jealousy accounted for the links between PDT and youth's depressive symptoms, self-worth, and risky behaviors. Additionally, we examined whether youth's perceptions of fairness regarding their treatment as well as the gender constellation of the dyad moderated these indirect relations (i.e., moderated-indirect effects). Participants were first- and second-born adolescent siblings ( M = 15.96, SD = .72 years for older siblings, M = 13.48, SD = 1.02 years for younger siblings) and their parents from 197 working and middle class European American families. Data were collected via home interviews. A series of Conditional Process Analyses revealed significant indirect effects of PDT through sibling jealousy to all three adjustment outcomes. Furthermore, perceptions of fairness moderated the relations between PDT and jealousy, such that the indirect effects were only significant at low (-1 SD ) and average levels of fairness. At high levels of fairness (+1 SD ) there was no association between PDT, jealousy, and youth adjustment. Taken together, results indicate that youth and parents would benefit from engaging in clear communication regarding the reasoning for the occurrence of differential treatment, likely maximizing youth and parent perceptions of that treatment as being fair, and in turn mitigating sibling jealousy and maladjustment.

    Parents' differential treatment is a common family dynamic that has been linked to youth's well-being in childhood and adolescence in European American families. Much less is known, however, about this family process in other ethnic groups. The authors examined the longitudinal associations between parents' differential treatment (PDT) and both depressive symptoms and risky behaviors of Mexican-origin sibling pairs from early adolescence through young adulthood. They also tested the moderating roles of cultural orientations as well as youth age, gender and sibling dyad gender constellation in these associations. Participants were mothers, fathers, and 2 siblings from 246 Mexican-origin families who participated in individual home interviews on 3 occasions over 8 years. Multilevel models revealed that, controlling for dyadic parent-child relationship qualities (i.e., absolute levels of warmth and conflict), adolescents who had less favorable treatment by mothers relative to their sibling reported more depressive symptoms and risky behavior, on average. Findings for fathers' PDT emerged at the within-person level indicating that, on occasions when adolescents experienced less favorable treatment by fathers than usual, they reported more depressive symptoms and risky behavior. However, some of these effects were moderated by youth age and cultural socialization. For example, adolescents who experienced relatively less paternal warmth than their siblings also reported poorer adjustment, but this effect did not emerge for young adults; such an effect also was significant for unfavored youth with stronger but not weaker cultural orientations.

    Full Text Available A homeopathic complex medication (HCM, with immunomodulatory properties, is recommended for patients with depressed immune systems. Previous studies demonstrated that the medication induces an increase in leukocyte number. The bone marrow microenvironment is composed of growth factors, stromal cells, an extracellular matrix and progenitor cells that differentiate into mature blood cells. Mice were our biological model used in this research. We now report in vivo immunophenotyping of total bone marrow cells and ex vivo effects of the medication on mononuclear cell differentiation at different times. Cells were examined by light microscopy and cytokine levels were measured in vitro. After in vivo treatment with HCM, a pool of cells from the new marrow microenvironment was analyzed by flow cytometry to detect any trend in cell alteration. The results showed decreases, mainly, in CD11b and TER-119 markers compared with controls. Mononuclear cells were used to analyze the effects of ex vivo HCM treatment and the number of cells showing ring nuclei, niche cells and activated macrophages increased in culture, even in the absence of macrophage colony-stimulating factor. Cytokines favoring stromal cell survival and differentiation in culture were induced in vitro. Thus, we observe that HCM is immunomodulatory, either alone or in association with other products.

    Differentiated thyroid carcinoma of follicular origin (DTCFO), although not very frequent, has registered a raising incidence in the last decades. In the majority of the cases, DTCFO is a curable disease when treated and monitored by experienced, multidisciplinary teams. These factors contribute to an increasing number of DTCFO survivors requiring life-long monitoring, due to the possibility of occurrence of recurrences many years after the initial treatment. Several aspects of the treatment and management of these patients are still controversial. The present protocol represents the consensus of the members of the Grupo de Estudo da Tiróide of the Sociedade Portuguesa de Endocrinologia, Diabetes e Metabolismo. It aims to define guidelines, in agreement with the current state of the art and contemplating the necessary adaptations to local constrains, that ensure decreased mortality and protection of patients' quality of life, avoiding unnecessarily aggressive or ineffective treatments, optimizing the use of the available resources.

    Many countries ravaged by conflict have substantial morbidity and mortality attributed to HIV/AIDS yet HIV treatment is uncommonly available. Universal access to HIV care cannot be achieved unless the needs of populations in conflict-affected areas are addressed. From 2003 Médecins Sans Frontières introduced HIV care, including antiretroviral therapy, into 24 programmes in conflict or post-conflict settings, mainly in sub-Saharan Africa. HIV care and treatment activities were usually integrated within other medical activities. Project data collected in the Fuchia software system were analysed and outcomes compared with ART-LINC data. Programme reports and other relevant documents and interviews with local and headquarters staff were used to develop lessons learned. In the 22 programmes where ART was initiated, more than 10,500 people were diagnosed with HIV and received medical care, and 4555 commenced antiretroviral therapy, including 348 children. Complete data were available for adults in 20 programmes (n = 4145). At analysis, 2645 (64%) remained on ART, 422 (10%) had died, 466 (11%) lost to follow-up, 417 (10%) transferred to another programme, and 195 (5%) had an unclear outcome. Median 12-month mortality and loss to follow-up were 9% and 11% respectively, and median 6-month CD4 gain was 129 cells/mm 3.Patient outcomes on treatment were comparable to those in stable resource-limited settings, and individuals and communities obtained significant benefits from access to HIV treatment.

  15. Provision of fertility services for women at increased risk of complications during fertility treatment or pregnancy: an Ethics Committee opinion.

    Science.gov (United States)

    2016-11-01

    This opinion addresses the ethics of providing fertility treatment to women at elevated risk from fertility treatment or pregnancy. Providers ethically may treat women at elevated risk provided that they are carefully assessed; that specialists in their medical condition are consulted as appropriate; and that patients are fully informed about risks, benefits, and alternatives, including oocyte and embryo donation, use of a gestational surrogate, not undergoing fertility care, and adoption. Providers also may conclude that the risks are too high for them to treat particular patients ethically; such determinations must be made in a medically objective and unbiased manner and patients must be fully informed of the decision. Counseling of women who wish to initiate fertility treatment with underlying medical conditions that confer increased risk during treatment or pregnancy should incorporate the most current knowledge available, being cognizant of the woman's personal determinants in relation to her reproductive desires. In such a way, both physician and patient will optimize decision making in an ethically sound, patient-supportive context. Copyright © 2016 American Society for Reproductive Medicine.

  16. Control of treatment of differentiated thyroid carcinoma by measurement of thyroglobulin in serum

    Hagemann, J.; Schneider, C.

    1978-01-01

    The presence of thyroglobulin in serum of patients with differentiated thyroid carcinoma was studied by a specific radioimmunoassay. Seventy-three patients with thyroid carcinomata were examined, 16 of whom had pulmonary or skeletal metastase, 11 local metastases, and the others no metastases. Patients with generalized metastases had very high serum thyroglobulin concentrations while those with local metastases had slightly elevated or normal concentrations. Those with remaining thyroid tissue had mainly normal thyroglobulin levels and patients with neither metastases nor remaining thyroid tissue had undetectable serum thyroglobulin. In seven patients with metastases it was possible to observe the development of serum thyroglobulin after 131 I treatment. In all cases the serum thyroglobulin concentration paralleled the development of the clinical status. Elevated serum thyroglobulin was also found in benign thyroid diseases such as hyperthyroidism and endemic goitre. Measurement of thyroglobulin in serum is therefore of little value in differentiating between benign and malignant thyroid diseases, but it is a good method for the follow-up control of patients with differentiated thyroid carcinomata. Because normal thyroglobulin levels do not exclude local metastases, additional examinations are necessary if normal thyroglobulin levels are found. When thyroglobulin is undetectable, metastases can be excluded and the measurement of thyroglobulin in serum can replace all other methods in the follow-up control. (author)

    This study is intended to optimise expansion and differentiation of cultured human chondrocytes by growth factor application and to identify molecular markers to monitor their differentiation state. We dissected the molecular consequences of matrix release, monolayer, and 3D-alginate culture, growth factor optimised expansion, and re-differentiation protocols by gene expression analysis. Among 19 common cartilage molecules assessed by cDNA array, six proved best to monitor differentiation. Instant down-regulation at release of cells from the matrix was strongest for COL 2A1, fibromodulin, and PRELP while LUM, CHI3L1, and CHI3L2 were expansion-related. Both gene sets reflected the physiologic effects of the most potent growth-inducing (PDGF-BB) and proteoglycan-inducing (BMP-4) factors. Only CRTAC1 expression correlated with 2D/3D switches while the molecular phenotype of native chondrocytes was not restored. The markers and optimised protocols we suggest can help to improve cell therapy of cartilage defects and chondrocyte differentiation from stem cell sources.

  18. High-Dose Lanreotide in the Treatment of Poorly Differentiated Pancreatic Neuroendocrine Carcinoma: A Case Report

    2014-03-01

    Full Text Available Pancreatic neuroendocrine tumors (NETs, including poorly differentiated carcinomas (NECs, are rarely encountered. The majority of these tumors do not secrete excess hormones, but functioning NETs produce large amounts of vasoactive peptides and may cause carcinoid syndrome. Synthetic somatostatin analogs (SSAs have been widely used in NETs for control of hormonal syndromes. Here, we present a case of poorly differentiated, grade 3 pancreatic NEC associated with carcinoid syndrome, for which adequate symptom control was achieved for 2 years and 4 months using the long-acting SSA lanreotide Autogel®. In February 2009, a 55-year-old woman presented with episodes of flushing, diarrhea and epigastric pain. Imaging techniques revealed the presence of a metabolically active mass expressing somatostatin receptors in the hilar area of the liver. Histopathological examination confirmed the malignant nature of the mass, which was identified as a poorly differentiated grade 3 pancreatic NEC (TNM staging: T4NxM0. Therapeutic options were limited for the patient because of the extent of the primary mass involving the celiac axis, severe gastrointestinal toxicity experienced as a side effect of chemotherapy with cisplatin-etoposide and, later in the course of the disease, extensive liver metastases and carcinoid heart syndrome. Along with a palliative debulking surgery and right portal vein embolization, biotherapy with a high dose of lanreotide Autogel (120 mg/14 days contributed to alleviation of symptoms caused by hormone overproduction, even after the development of liver metastases. These results suggest that patients with poorly differentiated NECs who exhibit signs of carcinoid syndrome can benefit from treatment with somatostatin analogs.

    Full Text Available Relevance. Over the last decades, such technology substituting inpatient treatment as outpatient treatment has been actively discussed and used in practice. Despite this fact, many problems of outpatient treatment have not been solved in full, no effective leverages contributing to creating economic incentives for increasing the volume and range of medical services in day hospitals have been found in the mandatory medical insurance system.Objective. Based on an in-depth analysis of medical care provision to women with benign gynaecological neoplasms, to offer measures for improvement of medical care in outpatient facilities, particularly by using technologies substituting inpatient treatment, and to evaluate their effectiveness.Materials and methods. A comprehensive retrospective evaluation of outpatient and inpatient medical care was conducted in St. Petersburg over the period from 2008 to 2015. The information contained in the database of billed and paid invoices of the obligatory medical insurance system of St. Petersburg was studied. For the total period of eight years, the data on medical care provision to 81 622 women suffering from benign tumors of the female reproductive organs, particularly in day hospitals, were obtained. In the period 2015–2016, medical care provision to patients with benign neoplasms of the gynecological sphere was thoroughly analyzed.

    In this article, we explore within-family differences in the closeness of sibling ties in adulthood. Specifically, we consider the sibship as a network and investigate the ways in which perceptions of mothers' differential treatment play a role in within-family variations in sibling closeness in midlife. Data were analyzed from 2,067 adult sibling dyads nested within 216 later life families, collected as part of the Within-Family Differences Study-II. Respondents reported the greatest closeness to siblings whom they perceived as favored by their mothers when they were not favored themselves, whereas respondents were less likely to choose siblings whom they perceived as disfavored by their mothers when they did not perceive themselves as disfavored. Variability in the strength of sibling ties within families suggests that some individuals receive greater benefits from this relationship than do their brothers and sisters. These findings shed new light on such within-family variations in sibling closeness by identifying how specific patterns of maternal differential treatment draw offspring toward some siblings and away from others. © The Author 2014.

    Full Text Available Memory for medical recommendations is a prerequisite for good adherence to treatment, and therefore to ameliorate the negative effects of the disease, a problem that mainly affects people with memory deficits. We conducted a simulated study to test the utility of a procedure (the differential outcomes procedure, DOP that may improve adherence to treatment by increasing the patient’s learning and retention of medical recommendations regarding medication. The DOP requires the structure of a conditional discriminative learning task in which correct choice responses to specific stimulus-stimulus associations are reinforced with a particular reinforcer or outcome. In two experiments, participants had to learn and retain in their memory the pills that were associated with particular disorders. To assess whether the DOP improved long-term retention of the learned disorder/pill associations, participants were asked to perform two recognition memory tests, 1 hour and 1 week after completing the learning phase. The results showed that compared with the standard non-differential outcomes procedure (NOP, the DOP produced better learning and long-term retention of the previously learned associations. These findings suggest that the DOP can be used as a useful complementary technique in intervention programs targeted at increasing adherence to clinical recommendations.

  2. Histone deacetylases: a common molecular target for differentiation treatment of acute myeloid leukemias?

    2001-05-28

    Recent discoveries have identified key molecular events in the pathogenesis of acute promyelocytic leukemia (APL), caused by chromosomal rearrangements of the transcription factor RAR (resulting in a fusion protein with the product of other cellular genes, such as PML). Oligomerization of RAR, through a self-association domain present in PML, imposes an altered interaction with transcriptional co-regulators (NCoR/SMRT). NCoR/SMRT are responsible for recruitment of histone deacetylases (HDACs), which is required for transcriptional repression of PML-RAR target genes, and for the transforming potential of the fusion protein. Oligomerization and altered recruitment of HDACs are also responsible for transformation by the fusion protein AML1-ETO, extending these mechanisms to other forms of acute myeloid leukemias (AMLs) and suggesting that HDAC is a common target for myeloid leukemias. Strikingly, AML1-ETO expression blocks retinoic acid (RA) signaling in hematopoietic cells, suggesting that interference with the RA pathway (genetically altered in APL) by HDAC recruitment may be a common theme in AMLs. Treatment of APLs with RA, and of other AMLs with RA plus HDAC inhibitors (HDACi), results in myeloid differentiation. Thus, activation of the RA signaling pathway and inhibition of HDAC activity might represent a general strategy for the differentiation treatment of myeloid leukemias.

    Cnemidophorus uniparens is a parthenogenetic unisexual species of lizard in which each individual develops as a female, making it a unique animal model for the study of sexual differentiation. In one study, administration of exogenous testosterone before and/or after hatching influenced the development of the gonads, the accessory reproductive ducts, the renal sex segment of the mesonephric kidney, and the femoral glands, a secondary sex character. Testosterone treatment also affected the cross-sectional area of the gonad and the proportions of cortical and medullary tissues present in the developing gonad. The oviducts and femoral glands of testosterone-treated individuals were hypertrophied; the collecting tubules of the kidney of these animals contained granules, an androgen-dependent, sexually dimorphic character in squamate reptiles. In another study, testosterone, dihydrotestosterone, or estradiol were administered to C. uniparens embryos. No treatment effects on gonadal development were detected on the day of hatching. However, estradiol, but not testosterone and dihydrotestosterone, stimulated development of the oviducts. Taken together these studies suggest that androgen aromatization may play a role in sexual differentiation in lizards.

    Mesenchymal stem cells (MSCs) are multipotential cells and their therapeutic potency is under intense investigation. Studying the effect of different induction factors on MSCs could increase our knowledge about the differentiation potency of these cells. One of the most important sources of these factors in mammalian body is platelet. Platelet lysate (PL) contains many growth factors and therefore, it can be used as a differentiation inducer. In the present study, the effect of PL on differentiation of rat bone marrow MSCs into cardiomyocytes was studied. To study the differentiation-inducing effect of PL, MSCs were treated with 2.5, 5 and 10% PL. Early results of this study showed that PL in high concentrations (10%) induces adipogenic differentiation of MSCs. Therefore, to evaluate differentiation to cardiomyocytes, MSCs were cultured in media containing lower levels of PL (2.5% and 5%) and then cardiomyogenic differentiation was induced by treatment with 5-azacytidine. Differentiation of MSCs was evaluated using direct observation of beating cells, immunostaining and real-time PCR techniques. The results of qPCR showed that treatment with PL alone increased the expression of cardiac alpha actinin (CAA) being predictable by earlier observation of beating cells in PL-treated groups. The results of staining assays against cardiac alpha actinin also showed that there were stained cells in PL-treated groups. The results of the present study showed that PL is a powerful induction factor for differentiation of MSCs into different cell lines such as cardiomyocytes and adipocytes.

    Background: To exam the effect of radioactive iodine treatment for thyroid remnant ablation and/or distant metastasis. A total of 134 well-differentiated thyroid cancer patients with cervical lymphnode metastasis at the time of diagnosis were retrospectively reviewed at Chang Gung Medical Center in Taiwan from 1977 to 1995. Methods: Among them, 126 cases were papillary carcinomas and 8 cases were follicular carcinomas. The mean age was 37.0 ± 14.6 years old. After the operation, 127 (95 %) patients received 131 I treatment (mean dose: 146.6 ± 109.5 mCi, range 30 - 550 mCi) and long-term follow-up. The mean follow-up period is 5.9 ± 3.9 yrs. All patients were restage at the end of 1995. Clinical biochemical results were also analyzed. Results: Among 127 cases who received postoperative radioactive iodine treatment, the majority of cases (92.5 % in papillary ca. vs. 57.1 % in follicular ca.) improved to stage I, 11 (8.6 %) cases remained on the same disease and stages. 13 cases (10.2 %, 10 papillary and 3 follicular) deteriorated to stage III or IV. However, in the non-treatment group, only 33.3 % of papillary carcinoma patients improved to stage I and 16.7 % of the patients remained as stage II. There were 5 cases (3.7 %) of mortality. Two cases with stage IV papillary carcinomas died of metastatic or recurrent malignancy, and the other 2 cases with stage I or III papillary carcinomas died of tracheal cancer or valvular heart disease. One patient with stage IV follicular carcinoma died of cerebral vascular accident. Conclusions: Radioactive iodine ( 131 I) treatment plays a significant role in the management of well-differentiated thyroid carcinoma patients with cervical lymphnode metastasis. The effect of postoperative 131 I treatment on papillary carcinoma was better than that on follicular carcinoma. The optimal dosage and frequency of radioactive iodine treatment warrant further study. (author)

    Pollution of urban water bodies requires stringent control measures and the development of low-cost and highly efficient alternative technologies. In contrast to Constructed Wetlands, Floating Treatment Wetlands (FTWs) have the advantage of not requiring large surface of land since they operate in situ. However, there is limited information about their long-term evaluation while operating at field scale. The aim of this work was to assess the performance of FTWs using a combination of Pontederia sagittata and Cyperus papyrus for the improvement of the water quality and provision of ecosystem services of a eutrophic urban pond. The FTWs were built with low-cost material easy to acquire and to ensemble. Two FTWs (17.5m 2 and 33m 2 ) located in Pond 1 within a complex of 4 urban artificial ponds were evaluated for two years. They promoted an increase in the dissolved oxygen (D.O.) within a range of 15 to 67%, a removal of fecal coliforms in the range of 9 to 86% and a nitrate removal in the range of 9 to 76%. The plant productivity reached a maximum of 363g dm m -2 d -1 in the FTW1 and 536g dm m -2 d -1 in the FTW2 during the period March-June 2016. The TKN and the TP content in the plant were in the range of 18.3 to 28.1 and of 0.05 to 0.196gkg -1 dry matter, respectively. In conclusion, the tested FTWs have proved to be a very beneficial low-cost technology for the improvement of water quality and provision of ecosystem services. Copyright © 2017 Elsevier B.V.

    Full Text Available Bacterial wilt and grey mould in tomato plants are economically destructive bacterial and fungal diseases caused by Ralstonia solanacearum and Botrytis cinerea, respectively. Various approaches including chemical and biological controls have been attempted to arrest the tomato diseases so far. In this study, in vitro growths of bacterial R. solanacearum and fungal B. cinerea were evaluated using four different vitamins including thiamine (vitamin B1, niacin (vitamin B3, pyridoxine (vitamin B6, and menadione (vitamin K3. In planta efficacies of the four vitamin treatments on tomato protection against both diseases were also demonstrated. All four vitamins showed different in vitro antibacterial activities against R. solanacearum in dose-dependent manners. However, treatment with 2 mM thiamine was only effective in reducing bacterial wilt of detached tomato leaves without phytotoxicity under lower disease pressure (10⁶ colony-forming unit [cfu]/ml. Treatment with the vitamins also differentially reduced in vitro conidial germination and mycelial growth of B. cinerea. The four vitamins slightly reduced the conidial germination, and thiamine, pyridoxine and menadione inhibited the mycelial growth of B. cinerea. Menadione began to drastically suppress the conidial germination and mycelial growth by 5 and 0.5 mM, respectively. Grey mould symptoms on the inoculated tomato leaves were significantly reduced by pyridoxine and menadione pretreatments one day prior to the fungal challenge inoculation. These findings suggest that disease-specific vitamin treatment will be integrated for eco-friendly management of tomato bacterial wilt and grey mould.

    Pediatric thyroid cancer is a rare disease with an excellent prognosis. Compared with adults, epithelial-derived differentiated thyroid cancer (DTC), which includes papillary and follicular thyroid cancer, presents at more advanced stages in children and is associated with higher rates of recurrence. Because of its uncommon occurrence, randomized trials have not been applied to test best-care options in children. Even in adults that have a 10-fold or higher incidence of thyroid cancer than children, few prospective trials have been executed to compare treatment approaches. We recognize that treatment recommendations have changed over the past few decades and will continue to do so. Respecting the aggressiveness of pediatric thyroid cancer, high recurrence rates, and the problems associated with decades of long-term follow-up, a premium should be placed on treatments that minimize risk of recurrence and the adverse effects of treatments and facilitate follow-up. We recommend that total thyroidectomy and central compartment lymph node dissection is the surgical procedure of choice for children with DTC if it can be performed by a high-volume thyroid surgeon. We recommend radioactive iodine therapy for remnant ablation or residual disease for most children with DTC. We recommend long-term follow-up because disease can recur decades after initial diagnosis and therapy. Considering the complexity of DTC management and the potential complications associated with therapy, it is essential that pediatric DTC be managed by physicians with expertise in this area.

    The objectives of this study were: to provide restorations using the ART approach to pre-school children in Southern China in a kindergarten environment, using a high-strength glass-ionomer restorative material; to assess the acceptability of this approach and to evaluate on a longitudinal basis the restorations placed. A total of 170 ART restorations were placed in 95 children, aged 5.1 +/- 0.7 years, by seven final-year dental students using standard ART procedures and hand instruments. The restorations were evaluated every six months thereafter by two calibrated independent examiners using explorers and mouth-mirrors. 93% of the children reported that they did not feel pain during treatment and 86% were willing to receive ART restorations again. The cumulative 12- and 30-month survival rates of Class I restorations were 91% and 79%, respectively. The corresponding figures for Class V restorations were 79% and 70%, while those for Class II restorations were 75% and 51%. The failure rates of Class III and IV restorations were high with more than half of them scored as missing within the first year. The ART approach was shown to be acceptable to Chinese pre-school children for providing restorative dental care outside the traditional clinical setting. The success rates were high for Class I and V restorations in primary teeth, modest for Class II, and low for Class III and IV restorations.

    Radioiodine (RAI) is a cornerstone in the treatment of Differentiated Thyroid Cancer (DTC). In patients on haemodialysis due to End-Stage Renal Disease (ESRD), it must be used cautiously, considering the renal clearance of this radionuclide. Also, the safety of the procedure and subsequent long-term outcome is still not well defined. In 2001, we described a dosimetric method and short-term results in three patients, with a good safety profile. We hypothesize that our method is safe in a long-term scenario without compromising the prognosis of both renal and thyroid disease. Descriptive-retrospective study. A systematic search was carried out using our clinical database from 2000 to 2014. DTC and radioiodine treatment while on haemodialysis. peritoneal dialysis. Final sample n=9 patients (n=5 males), age 48 years (median age 51 years males, 67 years female group); n=8 papillary thyroid cancer, n=1 follicular thyroid cancer; n=5 lymph node invasion; n=1 metastatic disease. Median RAI dose administered on haemodialysis 100mCi. 7.5 years after radioiodine treatment on haemodialysis, n=7 deemed free of thyroid disease, n=1 persistent non-localised disease. No complications related to the procedure or other target organs were registered. After 3.25 years, n=4 patients underwent successful renal transplantation; n=4 patients did not meet transplantation criteria due to other conditions unrelated to the thyroid disease or its treatment. One patient died due to ischemic cardiomyopathy (free of thyroid disease). Radioiodine treatment during haemodialysis is a long-term, safe procedure without worsening prognosis of either renal or thyroid disease. Copyright © 2015 Elsevier España, S.L.U. and SEMNIM.

    This study examines the relationship between levels of psychological distress in substance-dependent mothers and their differential response to a dyadic parent-child intervention. A sample of 66 mothers who were receiving treatment for substance abuse, as well as a simultaneous parenting intervention, were interviewed pre and post-treatment on measures of psychological distress, adult and child trauma history, parental reflective functioning, and child social-emotional development. Additionally, clinicians provided assessments of the parent-child relationships. As anticipated, trauma histories for mothers and children, children's social emotional development, and parental reflective functioning were associated with aspects of maternal psychological distress. Kruskal-Wallis and subsequent Wilcoxson signed rank tests revealed that women with highest levels of baseline psychological distress showed significant improvements in psychological functioning post-treatment while women with moderately elevated levels of psychological distress did not. Women who were most distressed at baseline showed increased levels of parental reflective functioning post-treatment while women with moderate and lower levels of baseline psychological distress showed improvements on clinician-rated assessments of parent-child relationships. Chi Square analyses showed that parents who endorsed the highest levels of distress at baseline reported that their children's risk status regarding social-emotional development decreased post-treatment. Despite similarities in substance dependence, mothers in this sample had different needs and outcomes in the context of this parenting intervention due to variation in mental health. Given this variation, parenting interventions for substance-dependent mothers need to account for the individual differences in levels of psychological distress. Copyright © 2015 Elsevier Ltd.

    Patients with well-differentiated thyroid cancer have a good prognosis but a significant chance for local recurrence. In the past, limited surgery with postoperative 131I only for extremely high-risk cases or recurrence was not uncommon. As more aggressive surgical and postoperative treatments appear to gain wider acceptance, toxicity and long-term morbidity become more important issues. Our goal is to present the experience of a single institution with emphasis on oral side effects related to 131I as well as acute and chronic symptoms related to this diagnosis and their impact on quality of life. Fifty-seven patients were followed for a median time of 19.3 months. All patients received therapeutic 131I (mean dose, 154.7 mCi) between January 1, 1996 and August 30, 2002. Fifty-four patients (94.7%) were alive at the time of analysis. Sixteen (28.1%) required a second treatment: any sign of persistence resulted in retreatment. Complaints with 131I treatment included altered taste, 26.3%; acute xerostomia, 21.1%; and acute sialoadenitis, 15.8%. Chronic xerostomia occurred in 6 (35.3%) of all patients who received multiple treatments. The incidence of chronic xerostomia was reduced to 1 of 11 (9.1%) with amifostine pretreatment. Other chronic side effects associated with this disease included fatigue 54.4%, weight gain of more than 6 months duration 24.6%, with 12 (27.9%) of those under 60 experiencing an average gain of 2.3 kg from initial diagnosis. Review of treatment-related symptoms prompted policies to reduce toxicity including amifostine pretreatment for 131I therapy and thyrotropin (synthetic TSH) use in place of iatrogenic hypothyroidism for thyroglobulin testing and scanning.

    Full text: Although it is well known that radiation induces chromosomal aberrations, there is a lack of information on the in- vivo dose-effect relationship in patients receiving Iodine-131 treatment and the results of previous studies are controversial. In this study, the dicentric chromosomal aberrations (DCA) analysis method was employed to investigate acute and late chromosomal damage (CD) in the peripheral lymphocytes of 58 differentiated thyroid cancer patients who received dose 1,1 GBq of Iodine-131 (group A), and 34 patients who received dose 3,7 GBq of Iodine- 131 (group B). The mean 100 metaphase spreads were scored for each subject. The DCA frequencies in cultured peripheral lymphocytes were determined before treatment to assess basal DCA frequencies, on the 3rd day to assess acute DCA frequencies and 6 months later to assess late DCA frequencies. The basal, acute and late DCA frequencies were divided into two groups: 0,18%, 2,14% and 0,53% (group A) and 0,18%, 2,12 % and 0,89% (group B), respectively, and these values differed significantly at various time after treatment (p 2 = 0,987), and group B as Y= 32,71 + 0,189 X. (r = 0,9381, R 2 = 0,880). However, there was an interesting difference in comparison with in- vitro studies, in that we found the coefficient β to have a negative value, suggesting the disappearance of damaged lymphocytes from peripheral circulation in a dose- dependent manner following Iodine-131 treatment. Further studies are therefore needed to clarify the effect of the negative β value on biological dosimetry approach in continuous internal low LET radiation, as in the case of Iodine-131 treatment.

    Introduction Independent Sector Treatment Centres (ISTCs) were created to relieve pressure from Acute Hospital Trusts. In October 2011, an ISTC opened on the grounds of a hospital within the East and North Hertfordshire NHS Trust. Most elective orthopaedic procedures were transferred there. We investigated the effect on productivity of operating theatres working in the ISTC compared with those working in the Acute Hospital Trust (AHT). Methods A 3-month period of working at the AHT was compared with the same period 9-months later in the ISTC, which were termed 'pre-' and 'post-ISTC' opening, respectively. Data for upper limb (UL) as well as foot and ankle (F&A) surgery were collected. Differences in the number of lists and patients per list constituted usage analyses. Financial productivity was calculated from the latest Payment by Results (PbR) data. A two-tailed Mann-Whitney U-test at a confidence level of 95% was employed to compare costs between groups. Results The UL surgeon undertook 18 lists in both years with 66 patients (pre-ISTC) and 32 (post-ISTC), eliciting a reduction in productivity of 51.5%. There were 13 lists for F&A surgery pre-ISTC with 67 procedures, and 20 lists with 49 patients post-ISTC. Allowing for the difference in the number of lists, a reduction of 52.5% was noted. PbR analyses confirmed productivity of £169,695 (pre-ISTC) and £95,760 (post-ISTC) at a loss of £73,935 for the UL surgeon. F&A data revealed £97,801 (pre-ISTC) and £91,960 (post-ISTC) at a loss of £54,742 when correcting for the difference in the number of lists. There was a combined reduction in potential financial productivity of £128,677 over 3 months or £514,708 over 1 year. Discussion Implementation of the ISTC was detrimental to departmental efficiency, with <50% of the number of patients being treated and a marked reduction in financial productivity.

    2015-04-01

    Full Text Available Neuroendocrine differentiation (NED in prostate cancer is a well recognized phenotypic change by which prostate cancer cells transdifferentiate into neuroendocrine-like (NE-like cells. NE-like cells lack the expression of androgen receptor and prostate specific antigen, and are resistant to treatments. In addition, NE-like cells secrete peptide hormones and growth factors to support the growth of surrounding tumor cells in a paracrine manner. Accumulated evidence has suggested that NED is associated with disease progression and poor prognosis. The importance of NED in prostate cancer progression and therapeutic response is further supported by the fact that therapeutic agents, including androgen deprivation therapy, chemotherapeutic agents, and radiotherapy, also induce NED. We will review the work supporting the overall hypothesis that therapy-induced NED is a mechanism of resistance to treatments, as well as discuss the relationship between therapy-induced NED and therapy-induced senescence, epithelial-to-mesenchymal transition, and cancer stem cells. Furthermore, we will use radiation-induced NED as a model to explore several NED-based targeting strategies for development of novel therapeutics. Finally, we propose future studies that will specifically address therapy-induced NED in the hope that a better treatment regimen for prostate cancer can be developed.

    The aim of this study was to evaluate the clinical role of technetium-99m pertechnetate (Tc-99m) imaging in thyroidectomized differentiated thyroid cancer patients immediately before radioiodine-131 (I-131) treatment (Tx). Eighty-six consecutive post-total-thyroidectomy patients (15 men, 71 women; mean age: 46.8 years) with pathologically diagnosed differentiated thyroid cancer were retrospectively studied. Tc-99m imaging immediately before I-131 Tx using both patient-based and lesion-based measurements were analyzed and were further compared with those of post-Tx I-131 whole-body scans. For patients with unequivocally positive Tc-99m uptake, the sensitivity was 77% (patient-based) and 59% (site-based). The positive predictive value (PPV) was 100% for both patient-based and site-based measurements. If equivocal Tc-99m uptake was counted as positive, the sensitivity was 83 and 67%, and the PPV was 100 and 99% for patient-based and site-based measurements, respectively. (a) To increase sensitivity yet maintaining high PPV, equivocal Tc-99m uptake should be considered a positive finding. (b) The nearly 100% PPV of Tc-99m imaging immediately before I-131 Tx for remnant detection suggests that Tc-99m imaging not only serves as an alternative to low-dose I-131 scanning in the low-risk post-thyroidectomy patients but also provides a clue for the subsequent I-131 therapeutic dosage and even for the outcome prediction.

    A family systems perspective directs attention to the potentially different experiences and perspectives of family members. This study examined parents' differential treatment (PDT) of siblings, discrepancies between parent and youth reports of PDT, and their links with relationships between adolescents and their mothers and fathers across three years. Participants were first- (Time 1 M age = 15.71, SD = 1.07) and secondborn (Time 1 M age = 13.18, SD = 1.29) siblings from 381, predominately white, working and middle class families. Analyses revealed that siblings' perceptions of being favored predicted less conflict with and greater warmth from both mothers and fathers, primarily for secondborn adolescents. Larger discrepancies between maternal and youth reports of differential affection were linked to more maternal conflict and less warmth for firstborns. These findings may suggest a hierarchy within families: parents may serve as referents for firstborns and firstborns as referents for secondborns.

  19. Recent Advances in the Surgical Treatment of Differentiated Thyroid Cancer: A Comprehensive Review

    2013-01-01

    Full Text Available Differentiated thyroid cancers have become one of the fastest growing malignancies in the world. While surgery has remained the cornerstone of management of these tumors, the surgical approach has seen numerous innovations over the past few decades. The use of video-assistance and robotics has revolutionized thyroid surgery. This paper provides a comprehensive evaluation of the different approaches to thyroid surgery, the utility of prophylactic and therapeutic lymph node dissection, and evidence-based guidelines in the treatment of differentiated thyroid cancers. Minimally invasive video-ssisted thyroidectomy is both safe and effective in the hands of the trained surgeon and, in selected patient populations, has comparative perioperative morbidity and better cosmesis as compared to conventional open thyroidectomy. It is universally accepted that therapeutic central lymph node dissection should be performed when metastatic lymph nodes are identified on physical exam, ultrasound, or intraoperatively. In the absence of overt nodal metastasis, the role of elective prophylactic central lymph node dissection remains a matter of debate and prospective, randomized studies are warranted to evaluate the utility of this procedure.

    Full Text Available Acetyl-L-carnitine (ALC is a naturally occurring substance that, when administered at supra-physiological concentration, is neuroprotective. It is involved in membrane stabilization and in enhancement of mitochondrial functions. It is a molecule of considerable interest for its clinical application in various neural disorders, including Alzheimer's disease and painful neuropathies. ALC is known to improve the cognitive capability of aged animals chronically treated with the drug and, recently, it has been reported that it impairs forms of non-associative learning in the leech. In the present study the effects of ALC on gene expression have been analyzed in the leech Hirudo medicinalis. The suppression subtractive hybridisation methodology was used for the generation of subtracted cDNA libraries and the subsequent identification of differentially expressed transcripts in the leech nervous system after ALC treatment. The method detects differentially but also little expressed transcripts of genes whose sequence or identity is still unknown. We report that a single administration of ALC is able to modulate positively the expression of genes coding for functions that reveal a lasting effect of ALC on the invertebrate, and confirm the neuroprotective and neuromodulative role of the substance. In addition an important finding is the modulation of genes of vegetal origin. This might be considered an instance of ectosymbiotic mutualism.

    Full Text Available Abstract Background Mycophenolic acid (MPA is widely used as a post transplantation medicine to prevent acute organ rejection. In the present study we used proteomics approach to identify proteome alterations in human embryonic kidney cells (HEK-293 after treatment with therapeutic dose of MPA. Following 72 hours MPA treatment, total protein lysates were prepared, resolved by two dimensional gel electrophoresis and differentially expressed proteins were identified by QTOF-MS/MS analysis. Expressional regulations of selected proteins were further validated by real time PCR and Western blotting. Results The proliferation assay demonstrated that therapeutic MPA concentration causes a dose dependent inhibition of HEK-293 cell proliferation. A significant apoptosis was observed after MPA treatment, as revealed by caspase 3 activity. Proteome analysis showed a total of 12 protein spots exhibiting differential expression after incubation with MPA, of which 7 proteins (complement component 1 Q subcomponent-binding protein, electron transfer flavoprotein subunit beta, cytochrome b-c1 complex subunit, peroxiredoxin 1, thioredoxin domain-containing protein 12, myosin regulatory light chain 2, and profilin 1 showed significant increase in their expression. The expression of 5 proteins (protein SET, stathmin, 40S ribosomal protein S12, histone H2B type 1 A, and histone H2B type 1-C/E/F/G/I were down-regulated. MPA mainly altered the proteins associated with the cytoskeleton (26%, chromatin structure/dynamics (17% and energy production/conversion (17%. Both real time PCR and Western blotting confirmed the regulation of myosin regulatory light chain 2 and peroxiredoxin 1 by MPA treatment. Furthermore, HT-29 cells treated with MPA and total kidney cell lysate from MMF treated rats showed similar increased expression of myosin regulatory light chain 2. Conclusion The emerging use of MPA in diverse pathophysiological conditions demands in-depth studies to

    Purpose To investigate the risk and outcomes of second hematologic malignancies (SHMs) in a population-based cohort of patients with well-differentiated thyroid cancer (WDTC) treated or not with radioactive iodine (RAI). Methods Patients with WDTC were identified from SEER registries. Competing risk regression analysis was performed to calculate the risks of SHMs that occurred after WDTC treatment and outcomes after SHM development were assessed. Results Of 148,215 patients with WDTC, 53% received surgery alone and 47% received RAI. In total, 783 patients developed an SHM after a median interval of 6.5 years (interquartile range, 3.3 to 11.2 years) from WDTC diagnosis. In multivariable analysis, compared with those undergoing thyroidectomy alone, RAI treatment was associated with an increased early risk of developing acute myeloid leukemia (AML; hazard ratio, 1.79; 95% CI, 1.13 to 2.82; P = .01) and chronic myeloid leukemia (CML; hazard ratio, 3.44; 95% CI, 1.87 to 6.36; P < .001). This increased risk of AML and CML after RAI treatment was seen even in low-risk and intermediate-risk WDTC tumors. Occurrence of AML but not CML in patients with WDTC was associated with shorter median overall survival compared with matched controls (8.0 years v 31.0 years; P = .001). In addition, AML developing after RAI trended toward inferior survival compared with matched controls with de novo AML (median overall survival, 1.2 years v 2.9 years; P = .06). Conclusion Patients with WDTC treated with RAI had an increased early risk of developing AML and CML but no other hematologic malignancies. AML that arises after RAI treatment has a poor prognosis. RAI use in patients with WDTC should be limited to patients with high-risk disease features, and patients with WDTC treated with adjuvant RAI should be monitored for myeloid malignancies as part of cancer surveillance.

    Maxwell’s equations are derived in terms of differential forms in the four-dimensional Minkowski representation, starting from the three-dimensional vector calculus differential version of these equations. Introducing all the mathematical and physical concepts needed (including the tool of differential forms), using only knowledge of elementary vector calculus and the local vector version of Maxwell’s equations, the equations are reduced to a simple and elegant set of two equations for a unified quantity, the electromagnetic field. The treatment should be accessible for students taking a first course on electromagnetism. (paper)

The aim of this study was to characterize the clinical features of child-hood and adolescent DTC and evaluate the outcome and safety of radioiodine treatment. Methods: The records of 38 childhood and adolescent DTC cases, with 28 females and 10 males (mean age: 16.4 years) were reviewed. At diagnosis, all had metastatic lesions with 38 at regional lymph nodes, 15 at lung, 2 at brain and bone. Twenty-three had a total thyroidectomy, 7 had subtotal thyroidectomy, 5 had lobectomy, and 3 had other treatment. All received post-operative radioiodine therapy. All had follow-up for at least one year. Results: At the time of follow-up, all were survive (with a median follow-up of 5.13 years). Four-teen patients had no evidence of disease, 16 had partial remission, and 8 were stable disease. Conclusions: DTC of the thyroid in childhood and adolescent has high risks of residual/recurrence and metastasis. Post-thyroidectomy oral administration of radioiodine was an effective and safety adjuvant therapy for outcomes. (authors)

    Termite societies are characterized by a highly organized division of labor among conspicuous castes, groups of individuals with various morphological specializations. Termite caste differentiation is under control of juvenile hormone (JH), but the molecular mechanism underlying the response to JH and early events triggering caste differentiation are still poorly understood. In order to profile candidate gene expression during early soldier caste differentiation of the damp-wood termite, Hodotermopsis sjostedti, we treated pseudergates (workers) with a juvenile hormone analog (JHA) to induce soldier caste differentiation. We then used Suppressive Subtractive Hybridization to create two cDNA libraries enriched for transcripts that were either up- or downregulated at 24h after treatment. Finally, we used quantitative PCR to confirm temporal expression patterns. Hexamerins represent a large proportion of the genes upregulated following JHA treatment and have an expression pattern that shows roughly an inverse correlation to intrinsic JH titers. This data is consistent with the role of a JH "sink", which was demonstrated for hexamerins in another termite, Reticulitermes flavipes. A putative nuclear protein was also upregulated a few hours after JHA treatment, which suggests a role in the early response to JH and subsequent regulation of transcriptional events associated with soldier caste differentiation. Some digestive enzymes, such as endogenous beta-endoglucanase and chymotrypsin, as well as a protein associated to digestion were identified among genes downregulated after JHA treatment. This suggests that JH may directly influence the pseudergate-specific digestive system. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Generation of new β cells is an important approach in the treatment of type 1 diabetes mellitus (type 1 DM). Adipose tissue-derived stem cells (ADSCs) might be one of the best sources for cell replacement therapy for diabetes. Therefore, this work aimed to test the possible role of transplanted insulin-producing cells (IPCs) differentiated from ADSCs in treatment of streptozotocin (STZ) induced type I DM in rats. Type 1 DM was induced by single intra peritoneal injection with STZ (50 mg/kg BW). Half of the diabetic rats were left without treatment and the other half were injected with differentiated IPCs directly into the pancreas. ADSCs were harvested, cultured and identified by testing their phenotypes through flow cytometry. They were further subjected to differentiation into IPCs using differentiation medium. mRNA expression of pancreatic transcription factors (pdx1), insulin and glucose transporter-2 genes by real time PCR was done to detect the cellular differentiation and confirmed by stimulated insulin secretion. The pancreatic tissues from all groups were examined 2 months after IPC transplantation and were subjected to histological, Immunohistochemical and morphometric study. The differentiated IPCs showed significant expression of pancreatic β cell markers and insulin secretion in glucose dependent manner. Treatment with IPCs induced apparent regeneration, diffused proliferated islet cells and significant increase in C-peptide immune reaction. We concluded that transplantation of differentiated IPCs improved function and morphology of Islet cells in diabetic rats. Consequently, this therapy option may be a promising therapeutic approach to patient with type 1 DM if proven to be effective and safe. Copyright © 2018 Elsevier B.V. All rights reserved.

    Objective: The aim of this study was to investigate the clinical nursing and radiation protection measures of "1"3"1I therapy in patients with differentiated thyroid after operation. Methods: 806 patients with postoperative "1"3"1I treatment of differentiated thyroid carcinoma were included in this study. The study included three aspects: (1) data preparation, health education and psychological nursing before treatment; (2) observation and nursing and radiation protection for the quarantine period; (3) nursing and followup after treatment. Results: There were 11 cases with nausea and loss of appetite and 9 cases with insomnia, dreams and other symptoms in total 806 patients. 2 patients got Parotid swelling and mild pain for not taking VitC according to requirements, released after timely symptomatic treatment. The remaining patients were in stable condition, without obvious symptoms through the quarantine period. Conclusion: According to the characteristics of "1"3"1I treatment of differentiated thyroid cancer, it was important to do nurse service for patients in isolation period of treatment, take effective radiation protection measures, discover and treat patients timely with complications for securing smooth treatment and obtaining good clinical curative effect. Those measures would better to ensure the safety of patients and people around, avoid environmental pollution and make for rehabilitation of patients. (authors)

    Determination of psychophysiological effects of operant behavioural (OBT) and cognitive behavioural treatment (CBT) for fibromyalgia patients. One hundred and fifteen female patients randomized to OBT (N = 43), CBT (N = 42), or whole-body infrared heat (IH) (N = 30) were compared before and after group treatment as well as at 6- and 12-month follow-ups using intent-to-treat analysis (12 drop-outs). Thirty matched pain-free controls (CON) served as reference group for the initial psychophysiological analysis. Surface electromyogram (EMG), blood pressure, heart rate (HR) and skin conductance levels (SCL) were continuously recorded during adaptation, baseline, social conflict, mental arithmetic and relaxation tasks. At baseline, fibromyalgia patients showed higher SCL and HR, lower diastolic blood pressure and EMG in comparison to controls. OBT and CBT compared to IH significantly reduced pain intensity [OBT: effect size (ES) = 1.21 CI: 0.71-1.71, CBT: ES = 1.23, CI: 0.72-1.74]. OBT increased diastolic blood pressure [ES = 1.13, CI: 0.63-1.63 and CBT reduced SCL (ES) = -0.66, CI: -1.14-0.18] 12 months after treatment. Both CBT and OBT significantly increased EMG levels (OBT: ES = 0.97, CI: 0.48-1.46, CBT: ES = 1.17, CI: 0.67-1.68). In contrast, the IH group did not show any significant changes in the psychophysiological parameters. Increased diastolic blood pressure and decreased pain after OBT suggest a reactivation of baroreflex-mechanisms in fibromyalgia and a normalization of the blood pressure and pain functional relationship. Reduced SCL following CBT may indicate reduced general arousal levels. Increased muscle tension after CBT and OBT suggest a normalization of physical parameters. The reduction in pain seems to be mediated by different psychophysiological processes, providing support for mechanism-based treatments might be indicated for CBT and OBT.

    Introduction Pain present 6 months following root canal treatment (RCT) may be either of odontogenic or nonodontogenic origin. This is importance because treatments and prognoses are different; therefore the aim of this study was to provide specific diagnoses of patients reporting pain 6 months after receiving initial orthograde RCT. Methods We enrolled patients from the Midwest region of an existing prospective observational study of pain after RCT. Pain at 6 months was defined as ≥1 day of pain and average pain intensity of at least 1/10 over the preceding month. An Endodontist and an Orofacial Pain practitioner independently performed clinical evaluations, which included periapical and cone-beam CT radiographs, to determine diagnoses. Results Thirty-eight out of the 354 eligible patients in the geographic area (11%) met the pain criteria, with 19 (50%) consenting to be clinically evaluated. As the sole reason for pain, 7 patients (37%) were given odontogenic diagnoses (4 involving the RCT tooth, 3 involving an adjacent tooth). Eight patients (42%) were given nonodontogenic pain diagnoses (7 from referred temporomandibular disorder (TMD) pain, 1 from persistent dentoalveolar pain disorder (PDAP)). Two patients (11%) had both odontogenic and nonodontogenic diagnoses, while 2 (11%) no longer fit the pain criteria at the time of the clinical evaluation. Conclusion Patients reporting “tooth” pain 6 months following RCT had a nonodontogenic pain diagnosis accounting for some of this pain, with TMD being the most frequent nonodonotgenic diagnosis. Dentists should have the necessary knowledge to differentiate between these diagnoses to adequately manage their patients. PMID:25732400

    The mammalian Krueppel-like factor 6 (KLF6) is involved in critical roles such as growth-related signal transduction, cell proliferation and differentiation, development, apoptosis and angiogenesis. Also, KLF6 appears to be an emerging key factor during cancer development and progression. Its expression is thoroughly regulated by several cell-damaging stimuli. DNA damaging agents at lethal concentrations induce a p53-independent down-regulation of the klf6 gene. To investigate the impact of external stimuli on human klf6 gene expression, its mRNA level was analyzed using a cancer cell line profiling array system, consisting in an assortment of immobilized cDNAs from multiple cell lines treated with several cell-damaging agents at growth inhibitory concentrations (IC 50 ). Cell-damaging agents affected the klf6 expression in 62% of the cDNA samples, though the expression pattern was not dependent on the cell origin type. Interestingly, significant differences (p 50 concentrations of physical and chemical stimuli in a p53-dependent manner. Most of these agents are frequently used in cancer therapy. Induction of klf6 expression in the absence of functional p53 directly correlates with cell death triggered by these compounds, whereas it is down-regulated in p53+/+ cells. Hence, klf6 expression level could represent a valuable marker for the efficiency of cell death upon cancer treatment.

    Full Text Available Neurologic Post Treatment Lyme disease (nPTLS and Chronic Fatigue (CFS are syndromes of unknown etiology. They share features of fatigue and cognitive dysfunction, making it difficult to differentiate them. Unresolved is whether nPTLS is a subset of CFS.Pooled cerebrospinal fluid (CSF samples from nPTLS patients, CFS patients, and healthy volunteers were comprehensively analyzed using high-resolution mass spectrometry (MS, coupled with immunoaffinity depletion methods to reduce protein-masking by abundant proteins. Individual patient and healthy control CSF samples were analyzed directly employing a MS-based label-free quantitative proteomics approach. We found that both groups, and individuals within the groups, could be distinguished from each other and normals based on their specific CSF proteins (p<0.01. CFS (n = 43 had 2,783 non-redundant proteins, nPTLS (n = 25 contained 2,768 proteins, and healthy normals had 2,630 proteins. Preliminary pathway analysis demonstrated that the data could be useful for hypothesis generation on the pathogenetic mechanisms underlying these two related syndromes.nPTLS and CFS have distinguishing CSF protein complements. Each condition has a number of CSF proteins that can be useful in providing candidates for future validation studies and insights on the respective mechanisms of pathogenesis. Distinguishing nPTLS and CFS permits more focused study of each condition, and can lead to novel diagnostics and therapeutic interventions.

    Extreme smog can have potentially harmful effects on human health, the economy and daily life. However, the average (mean) values do not provide strategically useful information on the hazard analysis and control of extreme smog. This article investigates China's smog extremes by applying extreme value analysis to hourly PM2.5 data from 2014 to 2016 obtained from monitoring stations across China. By fitting a generalized extreme value (GEV) distribution to exceedances over a station-specific extreme smog level at each monitoring location, all study stations are grouped into eight different categories based on the estimated mean and shape parameter values of fitted GEV distributions. The extreme features characterized by the mean of the fitted extreme value distribution, the maximum frequency and the tail index of extreme smog at each location are analysed. These features can provide useful information for central/local government to conduct differentiated treatments in cities within different categories and conduct similar prevention goals and control strategies among those cities belonging to the same category in a range of areas. Furthermore, hazardous hours, breaking probability and the 1-year return level of each station are demonstrated by category, based on which the future control and reduction targets of extreme smog are proposed for the cities of Beijing, Tianjin and Hebei as an example.

  16. Tendinitis of the Temporalis muscle: Differential diagnosis and treatment. A Case Report.

    Full Text Available Introduction: The temporalis muscle plays an essential role in mastication and is actively involved in the mandibular closing movement. It is covered by a fibroelastic fascia that forms its tendon. Tendinitis is a degenerative and inflammatory process, which originates in the tendon-bone junction. Signs and symptoms such as swelling, pain, tenderness on palpation, limitation of movement and mouth opening are frequently associated with other temporomandibular disorders and not with tendinitis as a causal factor. Objective: To describe a clinical case identifying the diagnostic process and management of tendinitis of the temporalis muscle. Case report: A 30-year old male patient who sought treatment after continuous squeezing pain in the zygomatic and bilateral temporal regions with increased pain during mouth opening and mandibular function. The patient referred pain in the insertion region of the tendon of the temporalis muscle. Pain was removed after using anesthesia, consequently confirming the diagnosis of tendinitis of the temporalis muscle. Primary management measures were performed and then peritendinous corticosteroids were administered. The patient did not refer spontaneous or functional pain during check-up. Conclusion: Tendinitis of the temporalis muscle is a common condition, although frequently underdiagnosed. A good differential diagnosis must be performed to avoid confusion with other common conditions such as odontogenic pain, sinusitis, arthralgia, myofascial pain and migraine. Management depends on the type of tendinitis. It usually occurs in conjunction with other types of TMD or facial pain, so it is important to know the different clinical characteristics of pathologies with similar manifestations.

    Full text: Differentiated thyroid carcinoma (DTC) is an infrequent tumor in childhood. Its incidence is less than 1% among malignant neoplasm. Its treatment involves surgery, ablation with 131I and replacement with thyroxine. The aim of this study was to present our experience of using 131I as treatment for DTC in children under 18 years age, at the National Institute of Pediatrics, Mexico. This was a retrospective, longitudinal, observational and descriptive study that included 34 patients under 18 years age with DTC. We used clinical data, imaging, histopathology results and doses of 131I administered based on the extension of the disease after surgery (residual tissue, residual tissue with regional/distant metastasis and regional/distant metastasis with lung infiltration). The average follow-up time was 10 years (range: 0.33 - 23 years). Fisher's exact test and the Mann-Whitney test were used for the statistical analysis. Of the 34 patients, average age at diagnosis was 10.8 years (ranging from 6 to 17 years), 21 were females and 13 were males. The histopathological variety was papillary in 97% of the cases and follicular in 3%. At the time of initial diagnosis, the disease was intrathyroidal (76.4%) while (23.6%) had regional and distant metastases. Subtotal thyroidectomy was done in 60% of the patients while the remaining 40% had total thyroidectomy. An average single dose 3.4 GBq of 131I was administered to 14 patients (ranging 1.8 to 5.5 GBq). The remaining 20 patients with distant or lung metastasis received 2 to 6 doses ranging, 3.1 to 23.3 GBq (average of 9.7 GBq). Complete ablation was achieved in 21 cases (62%), while in 38% it could not be achieved. A significant number of children with intra thyroid DTC and regional metastasis achieved ablation with 131I doses between 3.7 and 5.5 GBq. With doses < 1.85 GBq, the probability of ablation was poor. Lung fibrosis was seen in 2 cases as a secondary effect. Average disease free survival was 9 years (41

    Full text of publication follows. Objective: serum thyroglobulin (Tg) measurements are usually the best marker of residual or metastatic disease after the treatment of differentiated thyroid carcinoma (DTC). It is not rare to find patients with detectable serum Tg levels after ablative 131 I treatment (AIT). The objective of this study is to establish the efficacy of empiric 131 I treatment (EIT) given for patients whose Tg levels remained high after AIT. Materials and methods: 28 patients (23 women, 5 men; mean age 47.4 ± 16.8) without distant metastasis, who were treated empirically for high Tg levels after AIT in our clinic were studied retrospectively. In all patients stimulated Tg levels before AIT (Tg I) and 6 months after AIT (Tg II) were measured. The Tg cutoff level for EIT was accepted 10 ng/ml. After EIT, post-therapeutic whole-body scintigraphy (PWBS) was performed to all patients. 18 F-FDG PET CT was performed to patients who had negative PWBS but continued high Tg II levels. Results: PWBS was positive in 14 patients (50%) and negative in 14 patients (50%). 14 patients did not respond to EIT (50%), and 14 patients (50%) responded to EIT at different rates. Eight patients (28.6%) responded to EIT completely, and 6 patients (21.4%) responded to EIT partially. Tg I was 60.7 ± 40 ng/ml and Tg II was 31 ± 20.4 ng/ml in responded patients. Tg I was 87.6 ± 96 ng/ml and Tg II was 114.3 ± 106 ng/ml in non-responding patients. 18 F-FDG PET CT was performed to 14 patients who had negative PWBS. 18 F-FDG PET CT was positive in 11 patients and negative in 3 patients. 18 F-FDG PET CT positive patients were referred to surgery. Conclusion: Our findings, suggested that the EIT is not beneficial in patients who have higher Tg II than Tg I and the cure rate is low in increasing Tg levels. The patients who have high Tg II but lower than Tg I can be treated empirically with 131 I. In these patients EIT may be beneficial. (authors)

    Full text: The most effective treatment against Differentiated Thyroid Cancer (DTC), in its most frequently types: papillar and follicular, is the administration of radioiodine. As a result of a multidisciplinary work, a dosimetrical protocol for radiological protection purpose has been developed that suggests the standards and formalisms for the determination of absorbed doses due to the administration of 131 I activity to DTC patients. This dosimetrical protocol takes into account individual data of each patient (age, gender, the presence or absence of metastases, physiology, physiopathology, biochemical parameters) and involves clinical aspects, the equipment that should be used and the dose assessment procedure of each treatment. Based on the Medical Internal radiation Dose (MIRD) scheme and considering the major critical organs for this therapy, the dosimetrical protocol states the 'how-to' of the following procedures, in adults and paediatric cases: 1) estimation of the red marrow dose (with/without bone metastases) to avoid mielotoxicity (200 cGy); 2) Estimation of the retention / dose rate / dose in lungs after 48 hours from the administration of radioiodine to avoid lung fibrosis; 3) Estimation of the testes dose in young male patients to avoid oligospermia; 4) Estimation of the maximum activity which can be safely administered without damaging the most critical organ for each patient; and 5) Acquisition of images and retention data from patients. This dosimetrical protocol also specifies the requirements and basic steps that should be followed, the essential information, the complementary studies and the basic equipment required to perform an appropriate internal dosimetry evaluation. To be fully implemented, the dosimetrical protocol needs the constitution of a multidisciplinary team including physicians, medical physicists and technicians. Clear instructions should be provided to the patient as his full collaboration is essential. Even though empirical

    Patients with differentiated thyroid cancer (DTC) often respond well to treatment but some become refractory to radioactive iodine (RAI) treatment, and treatment options are limited. Despite the humanistic and economic burden RAI refractory disease imposes on patients, published research concerning treatment patterns and health care resource utilization is sparse. Data were collected from an online retrospective chart review study in the US and five European Union (EU) countries (France, Germany, Italy, Spain, and UK) with physicians recruited from an online panel. Physicians (N=211) provided demographics, disease history, treatment information, and health care resource utilization for one to four of their patients with radioactive iodine refractory differentiated thyroid cancer (RR-DTC). The majority of the patients with RR-DTC (N=623) were female (56%), and their mean age was 58.2 years. In this sample, 63.2% had papillary thyroid cancer and 57.0% were in Stage IV when deemed RAI refractory. Patients with RR-DTC experienced regional recurrence in the thyroid bed/central neck area (25.3%) and had distant metastatic disease (53.6%). At the time data were collected, 50.7% were receiving systemic treatment. Of those, 78.5% were on first-line treatment and 62.7% were receiving multikinase inhibitors. Regional differences for prescribed treatments were observed; the US was more likely to have patients receiving multikinase inhibitors (79.2%) compared with UK (41.2%) and Italy (17.1%). Additional details regarding treatment patterns and resource utilization are discussed. The current study aimed to obtain a greater understanding of RR-DTC treatment globally. These results can assist in the development and implementation of treatment guidelines and ultimately enhance the care of patients with RR-DTC

    Osteoporosis is a systemic metabolic bone disorder characterized by a decrease in bone mass and degradation of the bone microstructure, leaving bones that are fragile and prone to fracture. Most osteoporosis treatments improve symptoms, but to date there is no quick and effective therapy. Bone marrow mesenchymal stem cells (BMMSCs) have pluripotent potential. In adults, BMMSCs differentiate mainly into osteoblasts and adipocytes in the skeleton. However, if this differentiation is unbalanced, it may lead to a decrease in bone mass. If the number of adipocyte cells increases and that of osteoblast cells decreases, osteoporosis can result. A variety of hormones and cytokines play an important role in the regulation of BMMSCs bidirectional differentiation. Therefore, a greater understanding of the regulation mechanism of BMMSC differentiation may provide new methods to prevent and treat osteoporosis. In addition, autologous, allogeneic BMMSCs or genetically modified BMMSC transplantation can effectively increase bone mass and density, increase bone mechanical strength, correct the imbalance in bone metabolism, and increase bone formation, and is expected to provide a new strategy and method for the treatment of osteoporosis.

    The mammalian Krueppel-like factor 6 (KLF6) is involved in critical roles such as growth-related signal transduction, cell proliferation and differentiation, development, apoptosis and angiogenesis. Also, KLF6 appears to be an emerging key factor during cancer development and progression. Its expression is thoroughly regulated by several cell-damaging stimuli. DNA damaging agents at lethal concentrations induce a p53-independent down-regulation of the klf6 gene. To investigate the impact of external stimuli on human klf6 gene expression, its mRNA level was analyzed using a cancer cell line profiling array system, consisting in an assortment of immobilized cDNAs from multiple cell lines treated with several cell-damaging agents at growth inhibitory concentrations (IC{sub 50}). Cell-damaging agents affected the klf6 expression in 62% of the cDNA samples, though the expression pattern was not dependent on the cell origin type. Interestingly, significant differences (p < 0.0001) in KLF6 mRNA levels were observed depending on the cellular p53 status upon cell damage. KLF6 expression was significantly increased in 63% of p53-deficient cells (122/195). Conversely, KLF6 mRNA level decreased nearly 4 fold in more than 70% of p53+/+ cells. In addition, klf6 gene promoter activity was down-regulated by DNA damaging agents in cells expressing the functional p53 protein whereas it was moderately increased in the absence of functional p53. Consistent results were obtained for the endogenous KLF6 protein level. Results indicate that human klf6 gene expression is responsive to external cell damage mediated by IC{sub 50} concentrations of physical and chemical stimuli in a p53-dependent manner. Most of these agents are frequently used in cancer therapy. Induction of klf6 expression in the absence of functional p53 directly correlates with cell death triggered by these compounds, whereas it is down-regulated in p53+/+ cells. Hence, klf6 expression level could represent a valuable

  5. Changes in the differential treatment of Rajput girls in Khalapur: 1955-1975.

    This article reports on data collected during 2 field trips to Khalapur. The 1st, 1954-55, focused on child rearing. The 2nd, 1974-75, focused on changes in the status of Rajput women. In 1955, neglect of girls, particularly those suffering from longterm illness, resulted in sufficient female mortality to produce a striking preponderance of boys. In 1975, the number of children in the original families sampled had increased from 128 to 250, a rise of 277% in total number of living offspring. In the 1975 sample, 45% were girls. The factors that contributed to this increase in viability of daughters are examined. The overall health of the children had improved from the 50s to the 70s. The improvement in health may be linked to better nutrition and preventive medicine and to the presence of a government sponsored village health center. In 1975, the village had also acquired a semi-skilled midwife. Mothers' reports indicate that there is a 10% difference in the use of this more highly paid midwife to deliver boys. Education emerges as another important factor. In 1975, 75% of Rajput girls between 6-20 were literate or in school, a dramatic 61% increase from the 14% reported in 1955. Moreover, all of the children of educated mothers were in school. The increase in school enrollment figures reflect this improvement in girls' education. Norms for early marriage present strong barriers for college education of women. The greater education of Khalapur women seems to have emerged from the increased education of men. Educated men prefer literate wives. Therefore education becomes an asset in arranging a good marriage for daughters. The government has encouraged education and has facilitated that of girls by not requiring them to pay tuition in elementary school. Despite the obvious improvement in the treatment of girls, some evidence of differential neglect persists. Nonetheless, for the Khalapur Rajput, the overall picture is one of optimism. Finally, it is argued that in

    Objective Effective treatments for major depressive disorder exist, yet some patients fail to respond, or achieve only partial response. One approach to optimizing treatment success is to identify which patients are more likely to respond best to which treatments. The objective of this investigation was to determine if patient personality characteristics are predictive of response to either cognitive-behavioural therapy (CBT) or pharmacotherapy (PHT). Method Depressed patients completed the Revised NEO Personality Inventory, which measures the higher-order domain and lower-order facet traits of the Five-Factor Model of Personality, and were randomized to receive either CBT or PHT. Result Four personality traits—the higher-order domain neuroticism and 3 lower-order facet traits: trust, straightforwardness, and tendermindedness—were able to distinguish a differential response rate to CBT, compared with PHT. Conclusion The assessment of patient dimensional personality traits can assist in the selection and optimization of treatment response for depressed patients. PMID:18616856

    Full Text Available ABSTRACT Congenital heart diseases are important malformations that might compromise not only the patient's survival, but also his/her quality of life. We present the case of a female newborn who presented cardiovascular unbalance and cianosis in spite of her previous month of life without any complication. Her differential diagnosis was rather difficult, due not only to restrictions of exams available for diagnosis, but also to their sensibility and specificity. We discuss such differential diagnosis and the complicated development of the case.

    To establish the differential criteria for Binge Eating Disorder (BED) and Food Addiction (FA). We performed a detailed analysis of comparative diagnostic criteria for BED and Substance use disorder contained in the Diagnostic and Statistical Manual of Mental Disorders DSM-V. We applied the diagnostic criteria for both disorders to scientific publications on the issue of excessive eating in obese people, during the years 2005-2016, available on PubMed. We isolated specific similarities and differences between Binge Eating Disorder and Food Addiction. We formulated differential criteria for BED and FA. In BED as well as FA the following characteristics are apparent: preoccupation with food, excessive eating, loss of control over the amount of food and manner of eating, inability to change behavior, continuing behavior despite negative consequences, increased impulsiveness and emotional imbalance. Differences between BED and FA relate to the function of food, reaction to omitted food, psychological mechanisms of coping with excessive eating and body image, the issue of tolerance, withdrawal syndrome and the correlation between excessive eating and other areas of life. The criteria of differentiation between BED and FA concern the following: function of food, eating circumstances, reaction to the unavailability of food, awareness of the problem. Appropriate diagnosis of these disorders and their differentiation increases the chances of adequate treatment of obese patients.

  16. Sustained Low-Dose Treatment with the Histone Deacetylase Inhibitor LBH589 Induces Terminal Differentiation of Osteosarcoma Cells

    Full Text Available Histone deacetylase inhibitors (HDACi were identified nearly four decades ago based on their ability to induce cellular differentiation. However, the clinical development of these compounds as cancer therapies has focused on their capacity to induce apoptosis in hematologic and lymphoid malignancies, often in combination with conventional cytotoxic agents. In many cases, HDACi doses necessary to induce these effects result in significant toxicity. Since osteosarcoma cells express markers of terminal osteoblast differentiation in response to DNA methyltransferase inhibitors, we reasoned that the epigenetic reprogramming capacity of HDACi might be exploited for therapeutic benefit. Here, we show that continuous exposure of osteosarcoma cells to low concentrations of HDACi LBH589 (Panobinostat over a three-week period induces terminal osteoblast differentiation and irreversible senescence without inducing cell death. Remarkably, transcriptional profiling revealed that HDACi therapy initiated gene signatures characteristic of chondrocyte and adipocyte lineages in addition to marked upregulation of mature osteoblast markers. In a mouse xenograft model, continuous low dose treatment with LBH589 induced a sustained cytostatic response accompanied by induction of mature osteoblast gene expression. These data suggest that the remarkable capacity of osteosarcoma cells to differentiate in response to HDACi therapy could be exploited for therapeutic benefit without inducing systemic toxicity.

    Radioiodine-131 therapy is applied in patients with differentiated thyroid carcinoma (DTC), within the therapeutic scheme following thyroidectomy, for the ablation of thyroid remnants and treatment of metastatic disease. Several approaches for the selection of a therapeutic dose were applied. The aim of this therapy is to achieve a lethal dose in the tumor tissue, without exceeding the dose of tolerance in healthy tissues (doses greater than 2 Gy in bone marrow could lead to myelotoxicity). In this work, the treatment protocol used incorporates the assessment by biological dosimetry (BD) for estimating doses to whole body and bone marrow, to tailor patient's treatment. Biological Dosimetry prospective studies conducted on samples from patients with cumulative activities, before and after each therapeutic administration, allows to evaluate DNA damage and repair capacity in peripheral blood lymphocytes.

    The pain, swelling of salivary glands and dry mouth are not infrequent complication of the high dose radioiodine treatment in the patients with differentiated thyroid cancer. The purpose of this study was, by the dynamic salivary scintigraphy, to observe the change of the salivary function after the high dose (150-200 mCi) radioiodine treatment. From May 1987 to April 1988, the dynamic salivary scintigraphy with 5 mCi of 99m Tc-pertechnetate and gamma camera was performed before and 7 days after the radioiodine treatment in 7 patients with differentiated thyroid cancer. Just after the dynamic scintigraphy, the stimulation test with vitamin C solution of pH 3.0 and poststimulation scintigraphy were done, and the radioactivity uptake index, excretion fraction and salivary clearance after the stimulation were calculated for each gland. There was positive correlation between the radioactivity uptake index and excretion fraction after the stimulation. The salivary clearance after the stimulation was 18.96 ± 8.95 ml/min in the pretreatment state, and 14.37 ± 7.7 ml/min after the radioiodine treatment. After the radioiodine treatment, the radioactivity uptake index, excretion fraction and salivary clearance after the stimulation were significantly reduced in the parotid glands, but only the excretion fraction was reduced in the submandibular glands. The more the pretreatment salivary clearance after the stimulation was, the % change after the treatment was smaller. Further studies on the relation between the radiation dose in the salivary glands and the change of their function, and the long-term observation for the recovery of function are expected.

  1. Effect of EI-treatment in relation to physiological and biochemical traits in rice: delay in germination and its recovery with provision of glucose

    Rice seeds treated with 0.2 to 1.2 v/v % of ethyleneimine (EI) demonstrated increasingly delayed germination concomitant with increasing dose. At the time of germination, the release of storage products was slightly inhibited at lower doses and completely reduced at higher doses. With increasing time after germination the development of shoot length, content of reducing sugar and free amino acid, and synthesis of nucleic acid and protein in treated seeds, showed the same response pattern as the control, although at reduced levels in the treated seeds. Consequently, it is interpreted that the delay of germination is due to physiological dormancy, i.e. impaired release of dormancy which would normally yield active forms of enzymes. When treated seeds were cultured in [ 14 C]-glucose medium, the specific activity of [ 14 C]-glucose was higher in late-germinating seeds than in early-germinating seeds. Furthermore, the provision of glucose prevented the delay of germination, resulting in about a 10% increase in germination rate (survival rate), and yet had no effect on subsequent growth. Finally, it is concluded that the damage resulting in delayed germination and reduction of survival differs from the damage leading to inhibition of subsequent growth in that the former can be compensated for by provision of glucose while the latter cannot.

    Immune reactions play an important role in determining the biostimulation of bone formation, either in new bone formation or inflammatory fibrous tissue encapsulation. Macrophage cell, the important effector cells in the immune reaction, which are indispensable for osteogenesis and their heterogeneity and plasticity, render macrophages a primer target for immune system modulation. However, there are very few studies about the effects of macrophage cells on laser treatment-regulated osteogenesis. In this study, we used CO 2 laser as a model biostimulation to investigate the role of macrophage cells on the CO 2 laser stimulated osteogenesis. Bone morphogenetic protein 2 (BMP2) was also significantly up regulated by the CO 2 laser stimulation, indicating that macrophage may participate in the CO 2 laser stimulated osteogenesis. Interestingly, when laser treatment macrophage-conditioned medium were applied to human periodontal ligament cells (hPDLs), the osteogenesis differentiation of hPDLs was significantly enhanced, indicating the important role of macrophages in CO 2 laser-induced osteogenesis. These findings provided valuable insights into the mechanism of CO 2 laser-stimulated osteogenic differentiation, and a strategy to optimize the evaluation system for the in vitro osteogenesis capacity of laser treatment.

    Treatments including multiple nonpharmacological components have beneficial effects on the key symptoms of fibromyalgia, although effects are limited and often do not persist. In this study, we examined different patterns of clinical progress and the dynamic interplay between predictors and outcomes over time. Fibromyalgia patients (N=153; 135 women) followed a multidisciplinary group program spanning 12weeks, aimed at "regaining control over daily functioning". Anxiety, depression, pain coping and kinesiophobia were used as predictor variables. Outcome variables were pain severity, pain-related disability, physical functioning and functional interference. All variables were assessed at 3 moments: on the first and last day of treatment, and 12weeks after the last day of treatment. Overall treatment effects were analyzed using mixed model analyses. Latent class growth analysis identifying different treatment trajectory classes was used to investigate individual differences in treatment effects. Finally, cross-lagged structural equation models were used to investigate the dynamic interplay between predictors and outcomes over time. Only a fourth to a third of the total group showed improvement on the outcome variables. These patients had lower baseline anxiety, depression and kinesiophobia, and improved more on anxiety, depression and kinesiophobia. Physical well-being had a stronger effect on anxiety and depression than vice versa. Physical functioning predicted relative changes in kinesiophobia, while kinesiophobia predicted relative changes in pain-related disability. The results emphasize the importance of tailoring treatments to individual needs in order to improve overall effectiveness of treatment programs. Copyright © 2017. Published by Elsevier Inc.

    primary health care services for other reasons. The aim of the present study is to describe the differential characteristics of AD patients in primary care, distinguishing between those who receive treatment and those who do not, and their reasons for not seeking it. In a cross-sectional study patients were evaluated by their general practitioner (GP) and interviewed by a member of the research team. Sociodemographic, diagnostic and clinical data were collected. From 1,372 patients interviewed in Catalonia, 118 (8.6%) were diagnosed as AD. These patients showed a lower socioeconomic status (48.3% vs 33.3%, odds ratio 2.02), higher unemployment rates (32.2% vs 19.2 %, odds ratio 2.11), and greater psychological distress and disability. Patients with AD receiving treatment (16.9%), were older (44 vs 36 years of age), reported higher unemployment rates (66% vs 25.5%, odds ratio 6.32) and higher daily alcohol consumption (61.5 vs 23.7 grams), suggesting a more advanced disease. Patients with AD in general showed a higher degree of comorbidity compared to other patients, with patients in treatment showing the most elevated level. The main reasons given for not seeking treatment were shame, fear of giving up drinking and barriers to treatment. Taken together, the data suggest the need to implement earlier strategies for the detection and treatment of AD.

    Despite improvements in cancer therapy and treatments, tumor recurrence is a common event in cancer patients. One explanation of recurrence is that cancer therapy focuses on treatment of tumor cells and does not eradicate cancer stem cells (CSCs). CSCs are postulated to behave similar to normal stem cells in that their role is to maintain homeostasis. That is, when the population of tumor cells is reduced or depleted by treatment, CSCs will repopulate the tumor, causing recurrence. In this paper, we study the application of the CSC Hypothesis to the treatment of glioblastoma multiforme by immunotherapy. We extend the work of Kogan et al. (2008) to incorporate the dynamics of CSCs, prove the existence of a recurrence state, and provide an analysis of possible cancerous states and their dependence on treatment levels.

    A substantial number of patients with major depressive disorder (MDD) do not respond to treatment, and recurrence rates remain high. The purpose of this study was to examine a history of severe childhood abuse as a moderator of response following a 16-week acute treatment trial, and of recurrence over a 12-month follow-up. Participants included 203 adult outpatients with MDD (129 women; age 18-60). The design was a 16-week single-center randomized, open label trial of interpersonal psychotherapy, cognitive-behavioral therapy, or antidepressant medication, with a 12-month naturalistic follow-up, conducted at a university psychiatry center in Canada. The main outcome measure was Hamilton Depression Rating Scale scores at treatment end point. Childhood maltreatment was assessed at the completion of treatment using an interview-based contextual measure of childhood physical, sexual, and emotional abuse. Multiple imputation was adopted to estimate missing values. Patients with severe maltreatment were significantly less likely to respond to interpersonal psychotherapy than to cognitive-behavioral therapy or medication (OR = 3.61), whereas no differences among treatments were found in those with no history of maltreatment (ORs therapy than from interpersonal psychotherapy. However, these patients remain vulnerable to recurrence regardless of treatment modality.

    Full Text Available Background. The aims of this study were to assess patients’ preferences to wait or start systemic treatment and understand how patients would make tradeoffs between certain severe adverse events (AEs and additional months of progression-free survival (PFS. Materials and Methods. Adults in France, Germany, and Spain with a diagnosis of DTC and who have had at least one RAI treatment completed a direct-elicitation question and a discrete-choice experiment (DCE online. The direct-elicitation question asked respondents whether they would opt out of treatment when their tumor is RAI-R. In the DCE, respondents chose between 12 pairs of hypothetical RAI-R DTC treatment profiles. Profiles were defined by magnitudes of efficacy (PFS and safety (severe hand-foot skin reaction [HFSR], severe proteinuria, and severe hypertension. A main-effects random-parameters logit model was estimated. Results. 134 patients completed the survey. Most patients (86.6% opted for treatment rather than “wait and see” decision. Patients placed a greater weight on the risk of severe hypertension than the risk of proteinuria and HFSR. Conclusions. DTC patients showed preference toward treatment for RAI-R DTC over watchful waiting. Patients’ concerns about the risk of severe hypertension appeared to have had a greater effect on patients’ choice than severe proteinuria or HFSR.

    The in vitro study was carried out for detection of the cisplatin in free form and in culture medium, depending on various conditions of sonodynamic human ovarian cancer cells A2780 treatment by differential pulse polarography (DPP). For sonodynamic treatment, we used cisplatin alone and combined cisplatin/ultrasound treatments. The ultrasound exposure intensity of 1.0 and 2.0 Wcm 2 in far field for incubation periods 1, 24 and 48 h was used. The parameters of DPP measurements were - 1 s drop time, 5 mV.s -1 voltage scan rate, 50 mV modulation amplitude and negative scanning direction; platinum wire served as counter electrode and Ag|AgCl|3 M KCI as reference electrode. The results showed the dependence of free platinum quantities in culture medium on incubation time and treatment protocol. We found difference in concentration of free cisplatin between conventional application of cisplatin and sonodynamic treatment. The sonodynamic combined treatment of cisplatin and ultrasound field showed a higher cisplatin content in the culture medium than cisplatin treatment alone; a difference of 20% was observed for incubation time 48 h. The results also showed the influence of a time sequence of ultrasound and cytostatics in the sonodynamic treatment. The highest amount of free cisplatin in the solution was found for primary application of cisplatin and the subsequent ultrasound exposure. The quantity of free cisplatin increased with time, namely for time intervals 1-24 h. There was no difference between the DPP signal of cisplatin in reaction mixture containing cells in small quantities and micro-filtered mixture without cells. Thus, the DPP method is suitable for the detection and quantification of free cisplatin in the culture medium of cell suspension. Ultrasound field can be important factor during cytostatic therapy.

    Guided by Bowen theory, we investigated the relationships between parent-child triangulation, parental differential treatment (PDT), sibling warmth, and individual depressive symptoms in a sample of 77 sibling dyads, aged 18-25 years, recruited through undergraduate classes at a U.S. public University. Results of the actor-partner interdependence models suggested that being triangulated into parental conflict was positively related to both siblings' perception of PDT; however, as one sibling felt triangulated, the other perceived reduced levels of PDT. For both siblings, the perception of higher levels of PDT was related to decreased sibling warmth and higher sibling warmth was associated with fewer depressive symptoms. The implications of these findings for research and the treatment of depression in the college-aged population are discussed. © 2016 American Association for Marriage and Family Therapy.

    Objective: Three hundred and twelve thyroid carcinoma patients with metastasis treated by the multiple 'high dose' program were followed up for 10 years. The result of 131I adverse effect were accessed. Method 1 Treatment protocol: In case of lung and bone metastasis. 200mCi 131 I was administered each time. For patient with lymphatic metastasis, 150mCi 131 I was given each time. The interval between 2 doses was 4 month. 2 Assessment of results, 131 I scanning of negative 131 I scanning denotes cure. Lesion size decrease, reduction of number of foci or reductions of iodine uptake by the lesion, normal blood Tg indicated effective treatment. Treatment failure shows higher blood Tg, appearance of new lesions with ensuing death. 3 Adverse events - marrow inhibition pulmonary function affected ; parathyroid function affected; salivary glands affected; chromosome aberration. Result 1: of the 312 patients, 112 were cured (35.9%),effective 118 patients (60.2%). Treatment failed in 12 cases(3.8%).2 adverse events bone marrow inhibition. accumulation dose of 131I could produce temporary reversible inhibition of bone marrow, no aplastic anemia was evident. Effect of salivary gland function, reversible changes were seen. Sub maxilla glandular function was least affected. Effect of parathyroid function: PTH showed temporary change, without a single case of hypoparathyroidism. Effect of pulmonary function: no change what so ever without a single case of pulmonary fibrosis. Effect on chromosome: After treatment lymphocytes in peripheral blood showed aberration, in part of the patients radioaction tolerability increased. Conclusion: Multiple high dose therapy with treatment of metastatic thyroid carcinoma is an effective method. Indication can be extended to patients showing pathological lesion on operation. Adverse events was almost negligible percent and treatment was discussed. Good results were obtained no aplastic anemia. hypoparathyroidism, decrease of pulmonary function

    Little is known about the proportion of the Australian population using alcohol or other drugs who may seek treatment. There is a need to have some additional estimates of population morbidity which reflect harms associated with use. To determine Australian population rates of publicly funded community based specialised alcohol and other drug treatment and in-patient hospital care by those 'at risk', by drug type, sex and age. The design is secondary data analysis of publicly available datasets. We use the latest available complete data on Australian general population incidence of alcohol, cannabis amphetamines and ecstasy use (2007 National Drug Strategy Household Survey) and nationally collected administrative data on publicly funded specialised alcohol and other drug treatment services (2006-2007 Alcohol and Other Drug Treatment Services National Minimum Dataset) and public hospitals (2006-2007 National Hospital Morbidity Minimum Dataset) to calculate rates of drug treatment and in-patient hospital care per 1000 Australians. 'At risk' for alcohol is defined as being at risk of short term harm, as defined by the National Health and Medical Research Council (2001). 'At risk' for illicit drugs is defined as those exposed to potential harm through at least weekly use of cannabis, amphetamines and ecstasy use. Risky alcohol consumption followed by recent cannabis use appears to lead to most harm. Greater harm seems to be experienced by males rather than females. Younger adults (15-19 years) and older adults (40+ years) seem also to experience the highest rates of harm. It is possible to derive population estimates of harms associated with licit and illicit drugs use. Treatment rates vary across drug type, gender and age. Alcohol and cannabis are the substances whose use leads to the greatest demand for services. Ecstasy appears to generate few presentations for treatment. Publicly available data can be used to estimate harms associated with the use of particular

    Endocrine disruption (ED) effects due to pulp and paper mill effluents extracts involving different industrial procedures and effluent treatments (nontreated, primary, and secondary treated) were evaluated using immature triploid rainbow trout in a pulse-exposure toxicity experiment. The protocol involved the use of intraperitoneal injection of mill extracts (solid-phase extraction [SPE]) corrected for individual fish weight and included several laboratory standards (steroidal hormones and phytosterols). Biological endpoints at two different levels of biological organization were analyzed (molecular and individual organism). Results indicated that nonsignificant changes were observed in the individual physiological indices represented by condition factor, liver somatic index, and gonad somatic index during the experiment. Significant induction of liver ethoxyresorufin-O-deethylase activity was observed between different effluent treatments and experimental controls. Significant endocrine-disrupting effects at the reproductive level were observed in all effluent treatments involving significant increments in plasma vitellogenin (VTG) levels. Fish exposed to untreated effluent extracts had significantly higher VTG levels compared to fish exposed to primary and secondary treatment effluent extracts, indicating a decrease of the estrogenic effect due to the effluent treatment. The present study has shown that for the Chilean pulp and paper mill SPE extracts evaluated, an endocrine disruption effect was induced in immature triploid rainbow, reaffirming the significant estrogenic effects demonstrated previously in laboratory and field experiments.

    Young patients carriers differentiated thyroid carcinoma (DTC) are treated with high doses of I-131 for much of his life with very good prognosis and projects with paternity. However, there is scarce information on the effect of radioiodine on the male gonad and their future fertility. This therapy may compromise on a temporary and / or definitively the role of the germinal cells. The testicular irradiation depends on the blood flow, the dose of I-131 administered and of the presence or absence of metastasis pelvic near to the gonads. A single dose of 100 mCi of I-131 throws an absorbed dose at gonadal level of 50-150 cGy. It has been reported that absorbed doses of 50 cGy can produce transitory decrease spermatogenesis and higher doses can also affect the function of the Leydig cells [es

    We have recently shown that chronic fluoxetine treatment acted significantly increasing plasma norepinephrine and epinephrine concentrations both in control and chronically stressed adult male rats. However, possible effects of fluoxetine on catecholamine synthesis and re-uptake in adrenal medulla have been largely unknown. In the present study the effects of chronic fluoxetine treatment on tyrosine hydroxylase, a rate-limiting enzyme in catecholamine synthesis, as well as a norepinephrine transporter and vesicular monoamine transporter 2 gene expressions in adrenal medulla of animals exposed to chronic unpredictable mild stress (CUMS) for 4 weeks, were investigated. Gene expression analyses were performed using a real-time quantitative reverse transcription-PCR. Chronically stressed animals had increased tyrosine hydroxylase mRNA levels and decreased expression of both transporters. Fluoxetine increased tyrosine hydroxylase and decreased norepinephrine transporter gene expression in both unstressed and CUMS rats. These findings suggest that chronic fluoxetine treatment increased plasma catecholamine levels by affecting opposing changes in catecholamine synthesis and uptake.

    The occurrence rate of DTC in children and adolescents is not high. However, DTC in these patients has some distinct characteristics different from those in adult, such as larger tumor volume at diagnosis, early invasion of neck lymph nodes and early distant metastases, high NIS expression, high recurrence but higher overall survival rate. 131 I ablation is still one of the important treatment methods after surgery. Currently, there are 3 major dosage regimens adopted for 131 I treatment: prescribed dose without causing bone marrow suppression/toxicity, dose aiming at tumor ablation, and empirically fixed dose.

    Objective: To evaluate the efficacy and safety of recombinant human TSH(rhTSH)-aided 131 I treatment for DTC. Methods: A total of 144 patients with DTC who underwent total or near total thyroidectomy were retrospectively analyzed. The rhTSH-aided 131 I treatment of 3.7 GBq was performed in 72 cases (Group Ⅰ: euthyroid). Another 72 cases received radioiodine ablation treatment of 3.7 GBq after 4 to 6 weeks of thyroxine withdrawal (Group Ⅱ: hypothyroidism). Serum endogenous TSH, FT 3 , FT 4 and Tg were measured. The life qualities of both groups were observed, such as intolerance to cold, weight gain, constipation, motor retardation, skin dryness, periorbital edema and bone pain. Absence of visible uptake or uptake rate less than 1% was taken as complete ablation. The efficacy of 131 I treatment was evaluated. The life quality of both groups was evaluated by χ 2 test, and the effect of 131 I treatment was analyzed by t test. Results: Serum TSH was effectively improved in both groups before 131 I treatment. In group Ⅰ, TSH was higher than that of group Ⅱ ((141.26 ± 27.30) mU/L vs (70.57 ± 51.13) mU/L; t=2.435, P<0.05), and FT 3 , FT 4 were not significantly different before or after the injection of rhTSH. Tg was well stimulated in both groups with no statistical difference. Group Ⅱ exhibited more side effects, which included intolerance to cold 80.56% (58/72), weight gain 86.11% (62/72), constipation 15.28% (11/72), motor retardation 22.22% (16/72), skin dryness 56.94% (41/72), bone pain 2.78% (2/72), and no periorbital edema was found. Group Ⅰ had a higher quality of life than group Ⅱ, only few side effects were observed including dizziness and nausea 2.78% (2/72), bone pain 2.78% (2/72), and transient tachycardia 1.39% (1/72). The effect of 131 I treatment was evaluated by whole body scans with a diagnostic dose of 131 I. The complete ablation rate was 70.83% (51/72) in group Ⅰ and 66.67% (48/72) in group Ⅱ (χ 2 =0.58, P>0.05). Conclusion: The

  1. Binge-Eating Disorder and Comorbid Conditions: Differential Diagnosis and Implications for Treatment.

    Citrome, Leslie

    2017-01-01

    Many patients with symptoms of binge-eating disorder (BED) are not diagnosed. Perhaps the biggest obstacles are the failure of physicians to recognize BED as a distinct disorder and the lack of awareness among patients that binge-eating is a well-studied abnormal behavior that is amenable to treatment. In addition, patients may avoid seeking treatment because they feel a general sense of shame over their eating habits and do not want to bring up these symptoms during visits with their physicians. In general, negative attitudes and biases regarding overweight and obesity are common. The presence of medical and psychiatric comorbidities also contributes to the challenge of diagnosis, as many doctors focus on treating those comorbidities, thereby delaying treatment for the BED and leading to suboptimal care. Once BED is diagnosed along with any comorbid conditions, medications for the treatment of the comorbidities must be carefully considered so that BED symptoms are not exacerbated. © Copyright 2017 Physicians Postgraduate Press, Inc.

    Full Text Available Alterations in cardiac function were observed in antidepressants treated patients and published in several clinical reports. These detected changes could be either a consequence of the treatment or of depression itself, which has already been proved to be a risk factor in heart diseases. In order to determine a possible influence of chronic treatment with norepinephrinergic reuptake inhibitor, maprotiline, on the heart, we investigated gene expression of cardiac β-adrenoceptors both in controls and in animals with signs of depression. The rats were divided into two groups, unstressed controls and those exposed to chronic unpredictable mild stress (CUMS. The groups were further divided into two subgroups, one receiving daily intraperitoneal injections of vehicle (sterile water and another one maprotiline (10 mg/kg for four weeks. Tissue samples were collected after the last application. Gene expression of cardiac β1- and β2-adrenoceptor was determined using Real-time RT-PCR analysis. Our results show that in control animals expression of both adrenoreceptors was decreased in the right atria after 4 weeks of maprotiline application. Contrary, the same treatment led to a significant increase in expression of cardiac β1-adrenoceptor in the stressed rats, with no change in the characteristics of β2-adrenoceptor. Our findings might reflect the that molecular mechanisms are underlying factors involved in the development of cardiovascular diseases linked with antidepressant treatment.

    Contrast-enhanced MR imaging of the breast has been found to be valuable in the assessment of local recurrence of previously treated breast cancer. We looked specifically at the appearances of the skin and nipple of the treated breast in order to describe the appearances of post-treatment change and recurrence in this region. Thirty-nine women treated for breast cancer had MR imaging of one or both breasts reviewed retrospectively with particular attention to the nipple and skin. The skin and chest wall were assessed for patients with mastectomies. All available histology of the skin and/or nipple, obtained following MR imaging, was reviewed. In patients who did not undergo surgery following MR imaging, clinical follow-up was obtained. Six of 39 cases had nodular enhancing areas seen on MR imaging, which correlated with histology demonstrating tumour recurrence within the skin and/or nipple. Of the remaining 33 patients, changes of linear or diffuse enhancement were seen in the skin and/or nipple of 15 patients. These changes were shown to be benign post-treatment changes at surgery/biopsy in 4 cases or by clinical follow-up in the remainder. In this article we demonstrate differing patterns of contrast enhancement within the skin and nipple in recurrent breast carcinoma vs post-treatment changes. This suggests that contrast-enhanced MR imaging of the breast may be a useful tool in differentiating tumour recurrence from post-treatment changes within the skin and nipple. (orig.)

    Cell replacement therapy is a promising approach for the treatment of cardiac diseases. It is, however, challenged by a limited supply of appropriate cells. Therefore, we have investigated whether functional cardiomyocytes can be efficiently generated from human embryonic stem cells (hESCs). In this study, we developed an efficient protocol for the generation of functional cardiomyocytes from hESCs by combining hanging drop culture and 5-azacytidine, a well-known demethylating agent, and then evaluated the expression of cardiac-specific markers. hESCs were cultured both in the medium without or with 0.1, 1, or 10 microM of 5-azacytidine under a hanging drop culture. The expression of several cardiac-specific markers was determined by real-time PCR, RT-PCR, immunofluorescence, and confocal microscopy. To verify the structural and functional properties of hESC-derived cardiomyocytes, we performed electron microscopy and electrophysiological recording. The efficiency of beating cell generation was significantly improved in the hanging drop culture compared with that in suspension culture. Treatment of hESCs with 0.1 microM of 5-azacytidine for 1-3 days significantly increased the number of beating cells and simultaneously enhanced the expression of cardiac-specific markers. Transmission electron microscopy and electrophysiological recording showed that hESC-derived cardiomyocytes acquired structural and functional properties of cardiomyocytes. In conclusion, these results suggest that differentiation of hESCs into cardiomyocytes can be enhanced by the combination of hanging drop culture and 5-azacytidine treatment. Also the methylation status of genes related to cardiomyocyte development may play an important role in the differentiation of hESCs into cardiomyocytes.

    This study sought to investigate the genome-wide transcriptional effects of a combination of disease modifying anti-rheumatic drugs (tDMARD; methotrexate, sulfasalazine and hydroxychloroquine) in synovial tissues obtained from early rheumatoid arthritis (RA) patients. While combination DMARD strategies have been investigated for clinical efficacy, very little data exists on the potential molecular mechanism of action. We hypothesized that tDMARD would impact multiple biological pathways, but the specific pathways were unknown. Paired synovial biopsy samples from early RA patients before and after 6 months of tDMARD therapy were collected by arthroscopy (n = 19). These biopsies as well as those from subjects with normal synovium (n = 28) were profiled by total RNA sequencing. Large differences in gene expression between RA and control biopsies (over 5000 genes) were identified. Despite clinical efficacy, the expression of a restricted set of less than 300 genes was reversed after 6 months of treatment. Many genes remained elevated, even in patients who achieved low disease activity. Interestingly, tDMARD downregulated genes included those involved in T cell activation and signaling and plasmablast/plasma cell differentiation and function. We have identified transcriptomic signatures that characterize synovial tissue from RA patients with early disease. Analysis after 6 months of tDMARD treatment highlight consistent alterations in expression of genes related to T cell activation and plasmablast/plasma cell differentiation. These results provide novel insight into the biology of early RA and the mechanism of tDMARD action and may help identify novel drug targets to improve rates of treatment-induced disease remission.

  9. New strategies for the treatment of undifferentiated thyroid cancer and poorly differentiated thyroid cancer

    2006-01-01

    Undifferentiated thyroid cancer, which accounts for about 5-10% of thyroid cancer cases, is a very aggressive tumor with no effective treatment, since it lacks iodine uptake and does not respond to radio or chemotherapy. The prognosis of these patients is bad, due to the rapid growth of the tumor and the early development of metastasis. Oncogenes and tumor suppressor genes are involved in the genetic changes that underlie thyroid cancer, as all kinds of tumors. The characterization of these proteins is being exploited to delineate new therapeutic strategies for the treatment of this cancer. This work is focused on those compounds or therapeutic approaches that are being used in clinical essays or in animal models. (author) [es

    1999-08-01

    Full Text Available After in-vitro exposure to 0.05 μmol/L 9-nitrocamptothecin (9NC for periods of time longer than 5 days, 65% to 80% of the human malignant melanoma SB1 B cells die by apoptosis, whereas the remaining cells are arrested at the G2-phase of the cell cycle. Upon discontinuation of exposure to 9NC the G2-arrested cells resume cell cycling or remain arrested depending on the duration of 9NC exposure. In contrast to cycling malignant cells, the cells irreversibly arrested at G2 exhibit features of normal-like cells, the melanocytes, as assessed by the appearance of dendrite-like structures; loss of proliferative activity; synthesis of the characteristic pigment, melanin; and, particularly, loss of tumorigenic ability after xenografting in immunodeficient mice. Further, the expression of the cyclin-dependent kinase inhibitor p16 is upregulated in the 9NC-treated, G1-arrested, but downregulated in density G1-arrested cells, whereas the reverse is observed in the expression of another cyclin-dependent kinase inhibitor, p21. These results suggest that malignant melanoma SB1B cells that escape 9NC-induced death by apoptosis undergo differentiation toward nonmalignant, normal-like cells.

    Here we investigated alterations in the protein profile of Hep-2 treated with red propolis using two-dimensional electrophoresis associated to mass spectrometry and apoptotic rates of cells treated with and without red propolis extracts through TUNEL and Annexin-V assays. A total of 325 spots were manually excised from the two-dimensional gel electrophoresis and 177 proteins were identified using LC-MS-MS. Among all proteins identified that presented differential expression, most were down-regulated in presence of red propolis extract at a concentration of 120 μg/mL (IC50): GRP78, PRDX2, LDHB, VIM and TUBA1A. Only two up-regulated proteins were identified in this study in the non-cytotoxic (6 μg/mL) red propolis treated group: RPLP0 and RAD23B. TUNEL staining assay showed a markedly increase in the mid- to late-stage apoptosis of Hep-2 cells induced by red propolis at concentrations of 60 and 120 μg/mL when compared with non-treated cells. The increase of late apoptosis was confirmed by in situ Annexin-V analysis in which red propolis extract induced late apoptosis in a dose-dependent manner. The differences in tumor cell protein profiles warrant further investigations including isolation of major bioactive compounds of red propolis in different cell lines using proteomics and molecular tests to validate the protein expression here observed.

    Full Text Available We have recently shown that chronic fluoxetine treatment acted significantly increasing plasma norepinephrine and epinephrine concentrations both in control and chronically stressed adult male rats. However, possible effects of fluoxetine on catecholamine synthesis and re-uptake in adrenal medulla have been largely unknown. In the present study the effects of chronic fluoxetine treatment on tyrosine hydroxylase, a rate-limiting enzyme in catecholamine synthesis, as well as a norepinephrine transporter and vesicular monoamine transporter 2 gene expressions in adrenal medulla of animals exposed to chronic unpredictable mild stress (CUMS for 4 weeks, were investigated. Gene expression analyses were performed using a real-time quantitative reverse transcription-PCR. Chronically stressed animals had increased tyrosine hydroxylase mRNA levels and decreased expression of both transporters. Fluoxetine increased tyrosine hydroxylase and decreased norepinephrine transporter gene expression in both unstressed and CUMS rats. These findings suggest that chronic fluoxetine treatment increased plasma catecholamine levels by affecting opposing changes in catecholamine synthesis and uptake.

    Accelerated intermittent theta-burst stimulation (aiTBS) anti-depressive working mechanisms are still unclear. Because aiTBS may work through modulating the reward system and the level of anhedonia may influence this modulation, we investigated the effect of aiTBS on reward responsiveness in high and low anhedonic MDD patients. In this registered RCT (NCT01832805), 50 MDD patients were randomised to a sham-controlled cross-over aiTBS treatment protocol over the left dorsolateral prefrontal cortex (DLPFC). Patients performed a probabilistic learning task in fMRI before and after each week of stimulation. Task performance analyses did not show any significant effects of aiTBS on reward responsiveness, nor differences between both groups of MDD patients. However, at baseline, low anhedonic patients displayed higher neural activity in the caudate and putamen. After the first week of aiTBS treatment, in low anhedonic patients we found a decreased neural activity within the reward system, in contrast to an increased activity observed in high anhedonic patients. No changes were observed in reward related neural regions after the first week of sham stimulation. Although both MDD groups showed no differences in task performance, our brain imaging findings suggest that left DLPFC aiTBS treatment modulates the reward system differently according to anhedonia severity.

    The use of aspirin versus warfarin for treatment of patients after a Fontan procedure remains contentious. Current preference-based models of treatment across Australia and New Zealand show variation in care that is unlikely to reflect patient differences and/or clinical risk. We combine data from the Australian and New Zealand Fontan Registry and a home INR (International Normalised Ratio) monitoring program (HINRMP) from the Royal Children's Hospital (RCH) Melbourne, to estimate the cost difference for Fontan recipients receiving aspirin versus warfarin for 2015. We adopt a societal perspective to costing which includes cost to the health system (e.g. medical consults, pathology tests) and costs to patients and carers (e.g. travel and time), but excludes costs of adverse events. Costs are presented in Australian 2015 dollars; any costs from previous years have been inflated using appropriate rates from the Australian Bureau of Statistics. We find that warfarin patients face additional costs of $825 per annum, with the majority ($584 or 71%) of those borne by the patient or family. If aspirin is as clinically as effective as warfarin, Fontan recipients could be enjoying far less costly, invasive and time-consuming treatment. While achieving such clinical consensus can be difficult, economics shows us that there are large costs associated with a failure to achieve it. Copyright © 2017. Published by Elsevier B.V.

    Full Text Available Abstract Background Psychosocial stress caused by war, ongoing conflict, lack of security, and restricted access to resources promotes mental suffering and diseases in many resource-poor countries. In an exemplary setting, the present study compares the efficacy of psychosocial counselling with routine pharmacological treatment in a randomised trial in Mazar-e-Sharif (Afghanistan. Methods Help seeking Afghan women (N = 61, who were diagnosed with mental health symptoms by local physicians either received routine medical treatment(treatment as usual or psychosocial counselling (5-8 sessions following a specifically developed manualised treatment protocol. Primary outcome measures were symptoms of depression and anxiety assessed before treatment and at follow-up using the Hopkins Symptom Checklist and the Mini-International Neuropsychiatric Interview. Secondary outcome measures were psychosocial stressors and coping mechanisms. Results At 3-month follow-up, psychosocial counselling patients showed high improvements with respect to the severity of symptoms of depression and anxiety. In addition, they reported a reduction of psychosocial stressors and showed an enhancement of coping strategies. At the same time, the severity of symptoms, the quantity of psychosocial stressors and coping mechanisms did not improve in patients receiving routine medical treatment. Conclusion These results indicate that psychosocial counselling can be an effective treatment for mental illnesses even for those living in ongoing unsafe environments.

    106 patients, 114 W, 27 M, were thyroidectomized for differentiated thyroid cancer (follicular 29.3%-papillary 54.3%) with different stages of gravity (NO: 48.2% - N1: 32.8% - N2: 19%). Neck dissection was used in cases of involved nodes. One or several doses of 131 I were given to 126 subjects, 106 patients were treated with LT4 (mean daily dose: 2.5 micrograms/kg BW). 23 patients presenting intolerance to LT4 with non suppressed TSH for 13 of them were treated by an association of TRIAC + LT4. The follow up included a yearly check up involving clinical examination, plasma Tg and TSH assessment, neck ultrasonography and X-ray of the chest. Therapy was stopped for 4 weeks in cases with Tg above its detectable value and a total body scan performed with Tg and TSH controls. The mean duration of follow up was 94.5 +/- 67.7 months and extended to more than 5 years for 61% of the patients. We observed 22 relapses of the tumor with 4 deaths. Age less then 45 years, appears as the best factor of prognosis. 2 groups of patients were compared to evaluate the incidence of TSH suppression on the relapse free survival (group 1 n = 30 with a TSH 1 mU/l during the follow up). The relapse free survival was shorter in group 2 (p = 0.01). Association of TRIAC with LT4 leads to a reduction of the daily dose of LT4 (m = 25 micrograms/day) with a significant improvement of TSH suppression and clinical tolerance.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available A novel method to characterize the organic composition of aerosol particles has been developed. The method is based on organic vapor interaction with aerosol particles and it has been named an Organic Tandem Differential Mobility Analyzer (OTDMA. The OTDMA method has been tested for inorganic (sodium chloride and ammonium sulfate and organic (citric acid and adipic acid particles. Growth curves of the particles have been measured in ethanol vapor and as a comparison in water vapor as a function of saturation ratio. Measurements in water vapor show that sodium chloride and ammonium sulfate as well as citric acid particles grow at water saturation ratios (S of 0.8 and above, whereas adipic acid particles do not grow at S S = 0.75 and S = 0.79, respectively. Citric acid particles grow monotonously with increasing saturation ratios already at low saturation ratios and no clear deliquescence point is found. For sodium chloride and ammonium sulfate particles, no growth can be seen in ethanol vapor at saturation ratios below 0.93. In contrast, for adipic acid particles, the deliquescence takes place at around S = 0.95 in the ethanol vapor. The recrystallization of adipic acid takes place at S The results show that the working principles of the OTDMA are operational for single-component aerosols. Furthermore, the results indicate that the OTDMA method may prove useful in determining whether aerosol particles contain organic substances, especially if the OTDMA is operated in parallel with a hygroscopicity TDMA, as the growth of many substances is different in ethanol and water vapors.

    Changes in dopamine receptor subtype binding in different brain regions were examined after 28 days treatment of rats with haloperidol, raclopride, clozapine or SCH23390 using in vitro receptor autoradiography. [ 3 H]7-hydroxy-N,N-di-n-propyl-2-aminotetralin binding to dopamine D 3 receptors was not changed in any brain region by any of the drug treatments. [ 3 H]SCH23390 was only increased by chronic SCH23390 treatment. Haloperidol significantly increased [ 3 H]nemonapride and [ 3 H]spiperone binding to dopamine D 2 -like receptors in the caudate-putamen. In contrast, haloperidol caused a small, significant increase in [ 3 H]raclopride binding in the lateral caudate-putamen only. Raclopride also elevated, but to a lesser extent [ 3 H]nemonapride and [ 3 H]spiperone binding in caudate-putamen, whereas it did not affect [ 3 H]raclopride binding. Clozapine did not significantly change D 2 -like striatal binding of [ 3 H]nemonapride, [ 3 H]spiperone or [ 3 H]raclopride. The differences in radioligand binding suggest that [ 3 H]nemonapride and [ 3 H]spiperone may be binding to additional subsets of dopamine D 2 -like receptors (including D 4 -like receptors) that are not recognized by [ 3 H]raclopride, which has high affinity for D 2 and D 3 receptors only.Quantification of [ 3 H]nemonapride or [ 3 H]spiperone binding in the presence of 300 nM raclopride (to block D 2 and D 3 receptors) revealed that haloperidol, raclopride and clozapine up-regulated D 4 -like receptors in the caudate-putamen using either radioligand. These results suggest that D 4 -like receptors may be a common site of action of both typical and atypical antipsychotics. (Copyright (c) 1997 Elsevier Science B.V., Amsterdam. All rights reserved.)

    Three chitinases have been shown previously to be induced upon various stresses of bean leaves. Time course studies of mRNA accumulation of two of them (P3- and P4-chitinases) have been studied upon virus infection, mercuric chloride treatment and UV irradiation. In alfalfa mosaic virus (AlMV)-infected plants both mRNAs, absent in uninfected bean leaves, become detectable 36 h after inoculation. A maximum level of mRNAs is reached 84 h after inoculation and, whereas the amount of P3-ch mRNA decreases soon after having reached the maximum, the amount of P4-ch mRNA remains at high levels for several days. In mercuric chloride-treated leaves P4-ch mRNA becomes detectable 1-1.5 h after onset of treatment and a maximum level is observed between 6 h and 24 h after treatment; P3-ch mRNA becomes detectable later than P4-ch mRNA in treated leaves and reaches a maximum as late as 18 h after treatment has been applied. UV light also induces the synthesis of both mRNAs but, here again, important differences are observed in the accumulation rate of the two transcripts. The relative amounts of each mRNA induced by the different stresses have been compared. The most effective inducer of P3-ch mRNA is AlMV. In contrast, mercuric chloride induces P4-ch mRNA more efficiently than AlMV or UV light. We have also determined the complete nucleotide sequence of the cDNA encoding P3-chitinase that has been isolated from a cDNA library by using the cucumber lysozyme-chitinase cDNA as a probe. The 1072 bp P3-ch cDNA encodes a mature protein of 268 amino acid residues and the 25 residue NH2-terminal signal peptide of the precursor. Because of its high structural homology to the cucumber and Arabidopsis acidic chitinases as well as to the N-terminal amino acid sequence of the bifunctional lysozyme-chitinase from P. quinquifolia, bean P3-chitinase can be considered to belong to the class III chitinases. Southern blot analysis of bean genomic DNA revealed that P3-chitinase is encoded by a

    Stress fractures of the foot and ankle are a commonly encountered problem among athletes and individuals participating in a wide range of activities. This illustrated review, the second of two parts, discusses site-specific etiological factors, imaging appearances, treatment options, and differential considerations of stress fractures of the foot and ankle. The imaging and clinical management of stress fractures of the foot and ankle are highly dependent on the specific location of the fracture, mechanical forces acting upon the injured site, vascular supply of the injured bone, and the proportion of trabecular to cortical bone at the site of injury. The most common stress fractures of the foot and ankle are low risk and include the posteromedial tibia, the calcaneus, and the second and third metatarsals. The distal fibula is a less common location, and stress fractures of the cuboid and cuneiforms are very rare, but are also considered low risk. In contrast, high-risk stress fractures are more prone to delayed union or nonunion and include the anterior tibial cortex, medial malleolus, navicular, base of the second metatarsal, proximal fifth metatarsal, hallux sesamoids, and the talus. Of these high-risk types, stress fractures of the anterior tibial cortex, the navicular, and the proximal tibial cortex may be predisposed to poor healing because of the watershed blood supply in these locations. The radiographic differential diagnosis of stress fracture includes osteoid osteoma, malignancy, and chronic osteomyelitis.

  5. Neurogenesis and Increase in Differentiated Neural Cell Survival via Phosphorylation of Akt1 after Fluoxetine Treatment of Stem Cells

    2013-01-01

    Full Text Available Fluoxetine (FLX is a selective serotonin reuptake inhibitor (SSRI. Its action is possibly through an increase in neural cell survival. The mechanism of improved survival rate of neurons by FLX may relate to the overexpression of some kinases such as Akt protein. Akt1 (a serine/threonine kinase plays a key role in the modulation of cell proliferation and survival. Our study evaluated the effects of FLX on mesenchymal stem cell (MSC fate and Akt1 phosphorylation levels in MSCs. Evaluation tests included reverse transcriptase polymerase chain reaction, western blot, and immunocytochemistry assays. Nestin, MAP-2, and β-tubulin were detected after neurogenesis as neural markers. Ten μM of FLX upregulated phosphorylation of Akt1 protein in induced hEnSC significantly. Also FLX did increase viability of these MSCs. Continuous FLX treatment after neurogenesis elevated the survival rate of differentiated neural cells probably by enhanced induction of Akt1 phosphorylation. This study addresses a novel role of FLX in neurogenesis and differentiated neural cell survival that may contribute to explaining the therapeutic action of fluoxetine in regenerative pharmacology.

    In 54 consecutive patients who had retained bulky metastatic and/or locoregional lesions of DTC despite the exhaustion of other therapeutic options, we gave one to four courses of two consecutive daily intramuscular injections of rhTSH, 0.9 mg, followed by a therapeutic activity of 131 I per os on day 3. Fifty patients had received prior radioiodine treatment aided by l-thyroxine (T 4 ) withdrawal. We included in the study 23 patients who had received a trial of isotretinoin therapy for re-differentiation of confirmed de-differentiated metastases. In a blinded, within-patient comparison of post-therapy whole-body scans after the first rhTSH-aided and latest withdrawal-aided treatments in patients with functional metastases at baseline, 18 of 27 (67%) scan pairs were concordant, four (15%) were discordant in favour of the rhTSH-aided scan and five (19%) were discordant in favour of the withdrawal-aided scan. In total, 37 (74%) of 50 paired scans were concordant, eight (16%) favoured rhTSH and five (10%) favoured withdrawal. All differences appeared to be attributable to clinical causes, not to any difference between endogenous and exogenous TSH stimulation. Reflecting the biochemical activity of rhTSH and the release of thyroglobulin (Tg) due to tumour destruction, median serum Tg concentration rose approximately fourfold between baseline and day 6 of the rhTSH-aided treatment course. rhTSH was well tolerated, with mostly minor, transient toxicity, except for neck oedema in three patients with neck infiltrates and pathological spine fracture in one patient with a large vertebral metastasis. At 6 months, complete response occurred in one (2%), partial response in 12 (26%) and disease stabilisation in 19 (40%) of 47 evaluable patients. The rate of complete + partial response was 41% and that of disease stabilisation, 30%, in the 27 evaluable patients with functional metastases at baseline; the corresponding rates were 10% and 55% in the 20 evaluable patients with non

    To evaluate the outcome of a cohort of young women treated with progestin for fertility-sparing management of endometrial atypical hyperplasia (AH) and endometrial carcinoma (EC). This retrospective multicentre cohort study included women under the age of 40 years treated conservatively for AH and EC to preserve fertility using progestin for at least 3 months. Four inclusion criteria were defined: (i) the presence of AH or grade 1 EC confirmed by two pathologists (including a reference pathologist); (ii) the use of conservative management for fertility sparing; (iii) adequate radiological examination before conservative management; and (iv) a minimal follow-up time of one year. Twenty-two patients fulfilled the inclusion criteria (8 had EC, and 14 had AH). After progestin treatment, 17 patients responded. Among the 17 patients who experienced remission, three also experienced disease relapse. One patient initially diagnosed with AH experienced progression of her disease to stage IIIA EC. Ten pregnancies were achieved in eight patients. Fertility-sparing management using progestin offers the opportunity to fulfil maternal desires in young patients diagnosed with AH and EC. However, progression of the disease is possible and close follow-up is needed.

    Few studies on radiation protection recommendation for patients leaving hospitalization area after thyroid carcinoma treatment with iodine-131 are based on experimental determination of effective half life. The aim of this work was to calculate times of adhesion to restrictions for patients using one dose rate measurement at 30 cm the last day, just before leaving hospital. Dose rate measurements were achieved every day at two localizations (abdomen mid trunk and neck) during hospitalization. Data were fitted by a monoexponential or a biexponential model in order to derive the effective half life. We considered 7 exposure states between patient and neighboring. We showed, according to our realistic scatter state, a dose rate variation inversely proportional to the distance from patient. Effective half life is equal to 16 ± 6 h whatever the measurement localization. Thus the times of adhesion to restrictions is never greater than 2 days after 3 days of hospitalization. A simple table is given to allow the computation of restrictions times according to the dose rate measurement before the patient is discharged. This protocol is applied in our institution and gives whole satisfaction as far as the ALARA principle and the patient information are concerned. (author)

    Full Text Available Abstract Background Adherence to antipsychotics for schizophrenia is associated with favorable clinical outcomes. This study compared annual mental-health service utilization by recent medication adherence levels for patients treated for schizophrenia, and assessed whether adherence levels change from pre- to post-psychiatric hospitalization. Methods We analyzed data from a large prospective, non-interventional study of patients treated for schizophrenia in the United States, conducted between 7/1997 and 9/2003. Detailed mental-health resource utilization was systematically abstracted from medical records and augmented with patients' self report. Medication possession ratio (MPR with any antipsychotic in the 6 months prior to enrollment was used to categorize patients as: adherent (MPR ≥ 80%, N = 1758, partially adherent (MPR ≥ 60% Results Adherent patients had a lower rate of psychiatric hospitalization compared with partially adherent and non-adherent patients (p Conclusion Adherence is associated with lower utilization of acute care services and greater engagement in outpatient mental-health treatment. Adherence is a potentially dynamic phenomenon, which may improve, at least temporarily, following patients' psychiatric hospitalizations.

    Animal work on the behavioral effects of antipsychotic treatment suggests that different dosing regimens could affect drug sensitivity differently, with an intermittent treatment regimen tending to cause a sensitization effect, while a continuous treatment causing a tolerance. In this study, we explored how haloperidol (HAL) sensitization induced throughout adolescence and tested in adulthood was differentially impacted by these two dosing regimens in the conditioned avoidance response (CAR) test. We also examined how these two dosing regiments affected social interaction and social memory in adulthood. Male adolescent Sprague-Dawley rats were treated with HAL via either osmotic minipump (HAL-0.25 CONT; 0.25 mg/kg/day, n = 14) or daily injection (HAL-0.05 INT; 0.05 mg/kg/injection/day, sc, n = 14), or sterile water (n = 14) from postnatal days (PND) 44 to 71. HAL sensitization was assessed in a challenge test in which all rats were injected with HAL (0.025 and 0.05 mg/kg, sc) on PND 80 and PND 82. Two days later, half of the rats from each group (n = 7/group) were assayed in two 4-trial social interaction tests in which a subject rat was given four 5-min social encounters with a familiar or novel juvenile rat (PND 35–40) at 10 min intervals. Another half were tested in a quinpirole-induced hyperlocomotion assay to assess the potential HAL-induced change in D2-mediated function. Results show that only the intermittent dosing group under the HAL 0.05 mg/kg challenge showed a robust sensitization effect as rats in this group made significantly fewer avoidance responses than those in the vehicle and HAL-0.25 CONT groups. Adolescent HAL treatment did not affect social behavior and social memory, as rats from all 3 groups exhibited a similar level of social interaction and showed a similar level of sensitivity to the change of social stimuli. Similarly, adolescent HAL treatment also did not produce a long-lasting change in D2 function, as all 3 groups exhibited a

In the fifties, the complimentary use of 131 radioiodine after differentiated thyroid carcinoma (DTC) surgery was postulated. The aim of the study was to analyze our experience of the management of patients with DTC. Material and methods: An 18-year retrospective analysis was made including 109 patients with previous diagnosis of DTC, 90 % females, mean age 47 +/- 17 y.o. (range: 19-85 y.o). Tumoral histology was 67 % papillary, 28 % follicular and 5% non-determined in the medical record. First doses of 131 radioiodine were between 50 and 200 mCi. In all, 156 radioiodine doses were given and 6 patients received 4 doses or more, with total doses between 300 and 570 mCi. Results: The distribution of first and total radioiodine doses is presented in the table below. Of the group of patients who received a first radioiodine dose of less than 100 mCi post surgery, 79% were treated before 1990. Those who received 150mCi or more had cervical ganglionar compromise, trachea invasion or subtotal thyroidectomy. In 50% of the patients who received 4 or more doses, the first two doses were 50 mCi. It is important to mention that there was one patient who received 8 radioiodine doses in 4 years , seven of them were 50 mCi ( total dose 438 mCi). This patient presented trachea and larynx invasion in the early stages, with a persistent focus in the left supraclavicular region. She later developed pulmonary fibrosis, for which she was treated with complimentary radiotherapy (30 Gy), before dying. Distribution of radioiodine doses is presented. Conclusion: It is important to emphasize the validity of a first 131 radioiodine dose after surgery of DTC patients of 100 mCi or more, to obtain the ablation of the remaining thyroid tissue. This

    The impact of oral cancer and its treatment is well documented; therefore, oral rehabilitation (OH; eg, with prosthetics, osseointegrated implants, etc) can be indicated to restore some level of form, function, and well-being. The purpose of this study was to review the current literature and evaluate the impact of OH on quality of life (QoL) after ablative surgery. A systematic literature search was conducted using EMBASE, MEDLINE, and PsychINFO. The study population was composed of all articles published from 2000 to 2015. To be included, studies had to use validated, specific head and neck QoL measurements (European Organization for Research and Treatment of Cancer QoL Head and Neck Module or University of Washington QoL Questionnaire). Only 8 articles met these inclusion criteria. In this review, OH was the primary predictor variable and QoL was the primary outcome variable. The 8 articles reviewed used a range of designs, including 1 randomized controlled trial, 3 prospective cohort studies, 3 case series, and 1 single-measurement cross-sectional descriptive study. Sample sizes were small (n = 26 to 102), and there was limited randomization and control of intervention and comparator groups. The overall level of evidence was weak. All studies showed a link between OH and QoL, but the results varied in significance (P < .01 to P = .95). Overall, there appears to be improvement in QoL to varying degrees after OH. However, a more systematic use of QoL measurements is needed before any definitive conclusions can be drawn. Crown Copyright © 2016. Published by Elsevier Inc. All rights reserved.

    Differential display is a powerful technique for analyzing differences in gene expression. Oligo-dT cDNAstart codon targeted marker (cDNA-SCoT) technique is a novel, simple, cheap, rapid, and efficient method for differential gene expression research. In the present study, the oligo-dT anchored cDNA-SCoT technique was exploited to identify differentially expressed genes during several stress treatments in mango. A total of 37 primers combined with oligo-dT anchor primers 3side amplified approximately 150 fragments of 150 bp to 1500 bp in length. Up to 100 fragments were differentially expressed among the stress treatments and control samples, among which 92 were obtained and sequenced. Out of the 92 transcript derived fragments (TDFs), 70% were highly homologous to known genes, and 30% encoded unclassified proteins with unknown functions. The expression pattern of nine genes with known functions involved in several abiotic stresses in other species was confirmed by quantitative reverse transcription polymerase chain reaction (qRT-PCR) under cold (4 °C), salinity (NaCl), polyethylene glycol (PEG, MW 6000), and heavy metal treatments in leaves and stems at different time points (0, 24, 48, and 72 h). The expression patterns of the genes (TDF4, TDF7, TDF23, TDF45, TDF49, TDF50, TDF57, TDF91 and TDF92) that had direct or indirect relationships with cold, salinity, drought and heavy metal stress response were analyzed through qRT-PCR. The possible roles of these genes are discussed. This study suggests that the oligo-dT anchored cDNA-SCoT differential display method is a useful tool to serve as an initial step for characterizing transcriptional changes induced by abiotic stresses and provide gene information for further study and application in genetic improvement and breeding in mango.

    In striated muscle, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have differential effects on the metabolism of glucose and differential effects on the metabolism of protein. We have shown that, despite similar incorporation, treatment of C 2 C 12 myotubes (CM) with EPA but not DHA improves glucose uptake and protein accretion. We hypothesized that these differential effects of EPA and DHA may be due to divergent shifts in lipidomic profiles leading to altered proteomic profiles. We therefore carried out an assessment of the impact of treating CM with EPA and DHA on lipidomic and proteomic profiles. Fatty acid methyl esters (FAME) analysis revealed that both EPA and DHA led to similar but substantials changes in fatty acid profiles with the exception of arachidonic acid, which was decreased only by DHA, and docosapentanoic acid (DPA), which was increased only by EPA treatment. Global lipidomic analysis showed that EPA and DHA induced large alterations in the cellular lipid profiles and in particular, the phospholipid classes. Subsequent targeted analysis confirmed that the most differentially regulated species were phosphatidylcholines and phosphatidylethanolamines containing long-chain fatty acids with five (EPA treatment) or six (DHA treatment) double bonds. As these are typically membrane-associated lipid species we hypothesized that these treatments differentially altered the membrane-associated proteome. Stable isotope labeling by amino acids in cell culture (SILAC)-based proteomics of the membrane fraction revealed significant divergence in the effects of EPA and DHA on the membrane-associated proteome. We conclude that the EPA-specific increase in polyunsaturated long-chain fatty acids in the phospholipid fraction is associated with an altered membrane-associated proteome and these may be critical events in the metabolic remodeling induced by EPA treatment.

    Objective Differentiated care refers collectively to flexible service models designed to meet the differing needs of HIV-infected persons in resource-scarce settings. Decentralization is one such service model. Retention is a key indicator for monitoring the success of HIV treatment and care programs. We used multiple measures to compare retention in a cohort of patients receiving HIV care at “hub” (central) and “spoke” (decentralized) sites in a large public HIV treatment program in north central Nigeria. Methods This retrospective cohort study utilized longitudinal program data representing central and decentralized levels of care in the Plateau State Decentralization Initiative, north central Nigeria. We examined retention with patient- level (retention at fixed times, loss-to-follow-up [LTFU]) and visit-level (gaps-in-care, visit constancy) measures. Regression models with generalized estimating equations (GEE) were used to estimate the effect of decentralization on visit-level measures. Patient-level measures were examined using survival methods with Cox regression models, controlling for baseline variables. Results Of 15,650 patients, 43% were enrolled at the hub. Median time in care was 3.1 years. Hub patients were less likely to be LTFU (adjusted hazard ratio (AHR)=0.91, 95% CI: 0.85-0.97), compared to spoke patients. Visit constancy was lower at the hub (−4.5%, 95% CI: −3.5, −5.5), where gaps in care were also more likely to occur (adjusted odds ratio=1.95, 95% CI: 1.83-2.08). Conclusion Decentralized sites demonstrated better retention outcomes using visit-level measures, while the hub achieved better retention outcomes using patient-level measures. Retention estimates produced by incorporating multiple measures showed substantial variation, confirming the influence of measurement strategies on the results of retention research. Future studies of retention in HIV care in sub-Saharan Africa will be well-served by including multiple measures

    In majority of cases of differentiated thyroid carcinoma (DTC), the ablative radioiodine treatment shows high efficacy. In a small number of patients, mechanism of selective iodine uptake by the DTC cells is insufficient and alternative methods of diagnosis and treatment are needed. As demonstrated in vitro, DTC cells show expression of somatostatin recep-tors. Radiolabeled somatostatin analogs are widely used in the diagnosis of neuroendocrine tumors. The aim of the study was to evaluate the utility of peptide receptor scintigraphy with the use of 99mTc-EDDA/HYNIC-TOC in the diagnosis of DTC in patients with elevated thyroglobulin concentrations (Tg), negative WBS and no effect of the consecutive radioiodine therapies. Whole body scintigraphy as well as SPECT of neck and chest were performed 3 and 24 h after i.v. administration of 740 MBq 99mTc-EDDA/HYNIC-TOC. The obtained images were compared with other radionuclide and ra-diological imaging methods. Forty-three patients with DTC after surgery and ablative radioiodine treatment with negative WBS and elevated Tg were qualified. Patients' age: 18-83 years (mean 58.0). SRS showed foci of tracer accumulation in 29 cases (67.4%). Sensitivity was 69.0% specificity 78.6%. SRS correctly identified local recurrence in 8 pts., metastatic lymph nodes in 19 pts., lung metastases in 12 pts. and bone metastases in 5 pts. SRS showed high sensitivity in the detection of metastatic lymph nodes (100%) and bone metastases (83.3%) and lung metastases (63.2%). Positive SRS was found in pts. with higher Tg concentrations (130 ± 144 vs. 30 ± 54 ng/ml). Scintigraphy with the use of the studied technetium-99m-labeled somatostatin analog is useful in the evaluation of patients with advanced DTC. It shows relatively good sensitivity and specificity but not high enough to be recommended as a routine imaging method. The role of somatostatin receptor scintigraphy in DTC is complementary to other imaging modalities.

    Boron neutron capture therapy (BNCT) is a high linear energy transfer (LET) radiotherapy for cancer, which it is based on the nuclear reaction that occurs when boron-10 that it is a non radioactive isotope of the natural elemental boron, is irradiated with low energy thermal neutrons to produce an alpha particle and a nucleus of lithium-7. Both particles have a range smaller than the diameter of a cell causing cell tumor death without significant damage to the surrounding normal tissues. In previous studies we have shown that BNCT can be a possibility for the treatment of undifferentiated thyroid cancer (UTC). However, more than 80 % of patients with thyroid neoplasm present differentiated carcinoma (CDT). These carcinomas are treated by surgery followed by therapy with 131 I and mostly these forms are well controlled. But in some patients recurrence of the tumor is observed. BNCT can be an alternative for these patients in who the tumor lost the capacity to concentrate iodide. The aim of these studies was to evaluate the possibility of treating differentiated thyroid cancer by BNCT. Materials and Methods: The human cell lines of follicular (WRO) and papillary carcinomas (TPC-1) were grown in RPMI and modified DMEM medium respectively. Both supplemented with 10 % of SFB. The cell line of thyroid rat, FRTL-5, used as control normal, was cultured in DMEM/F12. The uptakes of 125 I and p-borophenylalanine BPA (6.93mM) were studied. The intracellular boron concentration was measured by inductively coupled plasma optical emission spectroscopy (ICP-OES) at 2 hr post incubation. The NIH strain of male nude mice, aged 6 to 8 weeks and weighing 20 to 25 g were implanted (s.c) in the back right flank with different concentrations of tumor cells. The size of the tumors was measured with a caliper twice or three times a week and the volume was calculated according the following formulae: A 2 x B/2 (were A is the width and B is the length). To evaluate the BPA uptake, animals

    Full Text Available Traditional Chinese medicine (TCM was formed two thousand years ago, and developed in the following centuries. TCM has a unique way of looking at health and illness. Zheng (syndrome is the basic unit and key term in TCM theory. Zheng is the pathological generalization of a certain stage in the development of disease. Treatment based on syndrome differentiation and disease differentiation of TCM is the basic principle to know and treat diseases,and a kind of special method to study diseases in TCM. In Han Dynasty (200 AD, doctor Zhang Zhongjing proposed Liujing Bianzheng (the differential diagnosis in accordance with the theory of six channels to diagnose and treat diseases in Treatise on Febrile and Miscellaneous Diseases. In other words, he divided diseases into six channels diseases based on patient’s Zhengs. Six channels diseases almost include all of the disease according to his classification standards. In addition, there are development rules in the progress of six channels diseases.Therefore, we hypothesized that combination of six channels disease and Zheng on the basic of differentiation of six channels is a new pattern of diagnosis and treatment diseases in TCM, which is beneficial to the understanding of a certain disease and makes disease treatment more convenient, fast and effective.

    Breast cancer patients' response to treatment is highly dependent on the primary tumor molecular features, with triple-negative breast tumors having the worst prognosis of all subtypes. According to the molecular features, tumors stimulate the microenvironment to induce distinct immune responses, baseline immune activation being associated with higher likelihood of pathologic response. In this study, we investigated the deconvolution of the immunological status of triple-negative tumors in comparison with luminal tumors and the association with patients' clinicopathological characteristics. Gene expression of 84 inflammatory molecules and their receptors were analyzed in 40 peripheral blood samples from patients with Her2- primary breast cancer tumors. We studied the association of triple-negative phenotype with age, clinical stage, tumor size, lymph nodes, and menopausal status. We observed that more patients with estrogen (ER)/progesterone (PR)-negative tumors had grade III, while more patients with ER/PR-positive tumors had grade II tumors. Gene expression analysis revealed a panel of 14 genes to have differential expression between the two groups: several interleukins: IL13, IL16, IL17C and IL17F, IL1A, IL3; interleukin receptors: IL10RB, IL5RA; chemokines: CXCL13 and CCL26; and cytokines: CSF2, IFNA2, OSM, TNSF13. The expression levels of these genes have been previously shown to be associated with reduced immunological status; indeed, the triple-negative breast cancer patients presented with lower counts of lymphocytes and eosinophils than the ER/PR-positive ones. These results contribute to a better understanding of the possible role of antitumor immune responses in mediating the clinical outcome.

    Full Text Available Abstract Background Fourier transform infrared spectroscopy (FTIR has been used as analytical tool in chemistry for many years. In addition, FTIR can also be applied as a rapid and non-invasive method to detect and identify microorganisms. The specific and fingerprint-like spectra allow - under optimal conditions - discrimination down to the species level. The aim of this study was to develop a fast and reproducible non-molecular method to differentiate pure samples of Bacillus spores originating from different species as well as to identify spores in a simple matrix, such as the clay mineral, bentonite. Results We investigated spores from pure cultures of seven different Bacillus species by FTIR in reflection or transmission mode followed by chemometrical data treatment. All species investigated (B. atrophaeus, B. brevis, B. circulans, B. lentus, B. megaterium, B. subtilis, B. thuringiensis are typical aerobic soil-borne spore formers. Additionally, a solid matrix (bentonite and mixtures of benonite with spores of B. megaterium at various wt/wt ratios were included in the study. Both hierarchical cluster analysis and principal component analysis of the spectra along with multidimensional scaling allowed the discrimination of different species and spore-matrix-mixtures. Conclusions Our results show that FTIR spectroscopy is a fast method for species-level discrimination of Bacillus spores. Spores were still detectable in the presence of the clay mineral bentonite. Even a tenfold excess of bentonite (corresponding to 2.1 × 1010 colony forming units per gram of mineral matrix still resulted in an unambiguous identification of B. megaterium spores.

    Full Text Available This study was conducted to elucidate the genome-wide gene expression profile in streptozotocin induced diabetic rat liver tissues in response to resveratrol treatment and to establish differentially expressed transcription regulation networks with microarray technology. In addition to measure the expression levels of several antioxidant and detoxification genes, real-time quantitative polymerase chain reaction (qRT-PCR was also used to verify the microarray results. Moreover, gene and protein expressions as well as enzymatic activities of main antioxidant enzymes; superoxide dismutase (SOD-1 and SOD-2 and glutathione S-transferase (GST-Mu were analyzed. Diabetes altered 273 genes significantly and 90 of which were categorized functionally which suggested that genes in cellular catalytic activities, oxidation-reduction reactions, co-enzyme binding and terpenoid biosynthesis were dominated by up-regulated expression in diabetes. Whereas; genes responsible from cellular carbohydrate metabolism, regulation of transcription, cell signal transduction, calcium independent cell-to-cell adhesion and lipid catabolism were down-regulated. Resveratrol increased the expression of 186 and decreased the expression of 494 genes in control groups. While cellular and extracellular components, positive regulation of biological processes, biological response to stress and biotic stimulants, and immune response genes were up-regulated, genes responsible from proteins present in nucleus and nucleolus were mainly down-regulated. The enzyme assays showed a significant decrease in diabetic SOD-1 and GST-Mu activities. The qRT-PCR and Western-blot results demonstrated that decrease in activity is regulated at gene expression level as both mRNA and protein expressions were also suppressed. Resveratrol treatment normalized the GST activities towards the control values reflecting a post-translational effect. As a conclusion, global gene expression in the liver tissues is

    Full Text Available Objective. To identify the optimum treatment protocol for insomnia among auricular, body, and abdominal needling methods. Methods. A three-factor (3 needling protocols and three-level experimental scheme was designed based on orthogonal method. 54 patients of insomnia differentiated as internal harassment of phlegm-heat syndrome were given two courses of acupuncture treatment (each with 20 times of acupuncture. The therapeutic effects were evaluated by comparing the Pittsburgh sleep quality index (PSQI, Hamilton Depression Scale (HAMD scores, and Hamilton Anxiety Scale (HAMA scores of patients before treatment, after one course of treatment, and after two courses of treatment as well as one month after treatment. Results. Body, auricular, and abdominal acupuncture treatments all alleviated symptoms of insomnia, depression, and anxiety, but body and auricular acupuncture had stronger therapeutic effects. Conclusions. Body acupuncture at basic points shall be given priority in protocol selection for insomnia. The second-best choice is auricular acupuncture with basic points combined with points based on Traditional Chinese Medicine (TCM theories. Abdominal needling with very quick effect can be an alternative protocol with basic points combined with syndrome differentiation points.

  9. Design provisions for safety

    International Nuclear Information System (INIS)

    Birkhofer, A.

    1983-01-01

    Design provisions for safety of nuclear power plants are based on a well balanced concept: the public is protected against a release of radioactive material by multiple barriers. These barriers are protected according to a 'defence-in-depth' principle. The reactor safety concept is primarily aimed at the prevention of accidents, especially fuel damage. Additionally, measures for consequence limitation are provided in order to prevent a severe release of radioactivity to the environment. However, it is difficult to judge the overall effectiveness of such devices. In a comprehensive safety analysis it has to be shown that the protection systems and safeguards work with sufficient reliability in the event of an accident. For the reliability assessment deterministic criteria (single failure, redundancy, fail-safe, demand for diversity) play an important role. Increasing efforts have been made to assess reliability quantitatively by means of probabilistic methods. It is now usual to perform reliability analyses of essential systems of nuclear power plants in the course of licensing procedures. As an additional level of emergency measures for a further reduction of hazards a reasonable amount of accident information has to be transferred. Operational experience may be considered as an important feedback to the design of plant safety features. Operator training has to include, besides skill in performing of operating procedures, the training of a flexible response to different accident situations. Experience has shown that the design provisions for safety could prevent dangerous release of the radioactive material to the environment after an accident has occurred. For future developments of reactor safety, extensive analyses of operating experience are of great importance. The main goal should be to enhance the reliability of measures for accident prevention, which prevent the core from meltdown or other damages

    Malignant small round cell tumor (SRCT) of the thoracopulmonary region appears to originate in the soft tissues of the chest wall or the peripheral lung. A differential diagnosis of poorly differentiated small round cell tumors which include Ewing's sarcoma of bone and soft tissue, embryonal rhabdomyosarcoma, Askin tumor, neuroblastoma, peripheral neuroectodermal tumor, small cell osteogenic sarcoma and lymphoma are after difficult by light microscopy alone. In recent, by the extensive studies electron microscopic examination, histochemical study, immunochemical study, cytogenetics and gene analysis, these tumors may be derived from the primitive and pluripotential cells, differentiating into mesenchymal, epithelial and neural features in variable proportions. Treatment for SRCT of thoracopulmonary regin is not determined because of massive involvement of the lung, pleura or soft tissues of the chest wall resulted in a dismal outcome despite aggressive surgery, irradiation and chemotherapy

    Axitinib, an antiangiogenic multikinase inhibitor (MKI), was evaluated in the compassionate use programme (CUP) in Spain (October 2012-November 2014). 47 patients with advanced radioactive iodine (RAI)-refractory differentiated thyroid cancer (DTC, n  = 34) or medullary thyroid cancer (MTC, n  = 13) with documented disease progression were treated with axitinib 5 mg b.i.d. The primary efficacy endpoint was objective response rate (ORR) by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1. Progression-free survival (PFS) and adverse events (AEs) were secondary objectives. Regulatory authorities validated the CUP, and all patients signed informed consent form. Axitinib was administered as first-line therapy in 17 patients (36.2%), as second-line in 18 patients (38.3%) and as third/fourth-line in 12 patients (25.5%). With a median follow-up of 11.5 months (0-24.3), ORR was 27.7% (DTC: 29.4% and MTC: 23.1%) and median PFS was 8.1 months (95% CI: 4.1-12.2) (DTC: 7.4 months (95% CI: 3.1-11.8) and MTC: 9.4 months (95% CI: 4.8-13.9)). Better outcomes were reported with first-line axitinib, with an ORR of 53% and a median PFS of 13.6 months compared with 16.7% and 10.6 months as second-line treatment. Twelve (25.5%) patients required dose reduction to 3 mg b.i.d. All-grade AEs included asthenia (53.2%), diarrhoea (36.2%), hypertension (31.9%) and mucositis (29.8%); grade 3/4 AEs included anorexia (6.4%), diarrhoea (4.3%) and cardiac toxicity (4.3%). Axitinib had a tolerable safety profile and clinically meaningful activity in refractory and progressive thyroid cancer regardless of histology as first-line therapy. To our knowledge, this is the first time that cross-resistance between MKIs is suggested in thyroid cancer, highlighting the importance of prospective sequential clinical studies. © 2017 European Society of Endocrinology.

During a treatment for a differentiated cancer of thyroid, the minimal activity of I 131 given to the patient is 3700 MBq producing a radiation dose to ovaries estimated to 140 mGy. In spite of the importance of this dose, few data on the outcomes of the pregnancy after irradiation are available. After our study it appears that the exposure to I 131 has no harmful effect on the outcomes of these pregnancies. (N.C.)

  13. Hybrid resource provisioning for clouds

    International Nuclear Information System (INIS)

    2012-01-01

    Flexible resource provisioning, the assignment of virtual machines (VMs) to physical machine, is a key requirement for cloud computing. To achieve 'provisioning elasticity', the cloud needs to manage its available resources on demand. A-priori, static, VM provisioning introduces no runtime overhead but fails to deal with unanticipated changes in resource demands. Dynamic provisioning addresses this problem but introduces runtime overhead. To reduce VM management overhead so more useful work can be done and to also avoid sub-optimal provisioning we propose a hybrid approach that combines static and dynamic provisioning. The idea is to adapt a good initial static placement of VMs in response to evolving load characteristics, using live migration, as long as the overhead of doing so is low and the effectiveness is high. When this is no longer so, we trigger a revised static placement. (Thus, we are essentially applying local multi-objective optimization to tune a global optimization with reduced overhead.) This approach requires a complicated migration decision algorithm based on current and predicted:future workloads, power consumptions and memory usage in the host machines as well as network burst characteristics for the various possible VM multiplexings (combinations of VMs on a host). A further challenge is to identify those characteristics of the dynamic provisioning that should trigger static re-provisioning.

    Full Text Available Although several linker histone variants have been studied in both animal and plant organisms, little is known about their distribution during processes that involve alterations in chromatin function, such as differentiation, dedifferentiation and hormone treatment. In this study, we identified linker histone variants by using specific anti-histone Hl antibodies. Each variant's ratio to total Hl in the three developmental zones of maize (Zea mays L. root and in callus cultures derived from them was estimated in order to define possible alterations either during plant cell differentiation or during their dedifferentiation. We also evaluated linker histone variants' ratios in the developmental zones of maize roots treated with auxin in order to examine the effects of exogenous applied auxin to linker histone variant distribution. Finally, immunohistochemical detection was used to identify the root tissues containing each variant and correlate them with the physiological status of the plant cells. According to the results presented in this study, linker histone variants' ratios are altered in the developmental zones of maize root, while they are similar to the meristematic zone in samples from callus cultures and to the differentiation zone in samples from roots treated with auxin. We propose that the alterations in linker histone variants' ratios are correlated with plant cell differentiation and dedifferentiation.

    Chronic arsenic toxicity is a global health problem that affects more than 100 million people worldwide. Long-term health effects of inorganic sodium arsenite in drinking water may result in skin, lung and liver cancers and in severe neurological abnormalities. We investigated in the present study whether sodium arsenite affects signaling pathways that control cell survival, proliferation and neuronal differentiation of human neural stem cells (NSC). We demonstrated that the critical signaling pathway, which was suppressed by sodium arsenite in NSC, was the protective PI3K–AKT pathway. Sodium arsenite (2–4 μM) also caused down-regulation of Nanog, one of the key transcription factors that control pluripotency and self-renewal of stem cells. Mitochondrial damage and cytochrome-c release induced by sodium arsenite exposure was followed by initiation of the mitochondrial apoptotic pathway in NSC. Beside caspase-9 and caspase-3 inhibitors, suppression of JNK activity decreased levels of arsenite-induced apoptosis in NSC. Neuronal differentiation of NSC was substantially inhibited by sodium arsenite exposure. Overactivation of JNK1 and ERK1/2 and down-regulation of PI3K–AKT activity induced by sodium arsenite were critical factors that strongly affected neuronal differentiation. In conclusion, sodium arsenite exposure of human NSC induces the mitochondrial apoptotic pathway, which is substantially accelerated due to the simultaneous suppression of PI3K–AKT. Sodium arsenite also negatively affects neuronal differentiation of NSC through overactivation of MEK–ERK and suppression of PI3K–AKT. - Highlights: ► Arsenite induces the mitochondrial apoptotic pathway in human neural stem cells. ► Arsenite-induced apoptosis is strongly upregulated by suppression of PI3K–AKT. ► Arsenite-induced apoptosis is strongly down-regulated by inhibition of JNK–cJun. ► Arsenite negatively affects neuronal differentiation by inhibition of PI3K–AKT

    This study was designed to compare the accuracy of the use of PET/CT and ultrasonography (US) for the detection of recurrence or a metastasis after surgical treatment in patients with differentiated thyroid carcinoma. A total of 128 patients with differentiated thyroid carcinoma, who had previously undergone a neck operation, were evaluated with the use of PET/CT and US. The two studies were performed within three months of each other. The presence of a metastasis or recurrence was based on histological results. Statistical values for FDG PET/CT and US findings were calculated statistically. Recurrence or a metastasis occurred in 40 of 128 patients. Thirty-one patients had lesions that were detected with the use of both PET/CT and US. Eight patients had lesions that were detected only with US. A lesion in one patient that had a high SUV on PET/CT was not detected by the use of US. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value for PET/CT were 80%, 82%, 82%, 68% and 90%, respectively. The corresponding values for US were 97%, 85%, 89%, 75% and 99%, respectively. The sensitivity and specificity for US were higher as compared to PET/CT, with no statistically significant difference. To detect recurrent or metastatic disease after surgical treatment in patients with differentiated thyroid carcinoma, US of the neck is a better screening modality as compared to the use of PET/CT

    Topical minoxidil is the only topical drug approved by the US Food and Drug Administration (FDA) for the treatment of androgenetic alopecia. However, the exact mechanism by which minoxidil stimulates anagen phase and promotes hair growth is not fully understood. In the late telegen phase of the hair follicle growth cycle, stem cells located in the bulge region differentiate and re-enter anagen phase, a period of growth lasting 2-6 years. In androgenetic alopecia, the anagen phase is shortened and a progressive miniaturization of hair follicles occurs, eventually leading to hair loss. Several studies have demonstrated that minoxidil increases the amount of intracellular Ca2+, which has been shown to up-regulate the enzyme adenosine triphosphate (ATP) synthase. A recent study demonstrated that ATP synthase, independent of its role in ATP synthesis, promotes stem cell differentiation. As such, we propose that minoxidil induced Ca2+ influx can increase stem cell differentiation and may be a key factor in the mechanism by which minoxidil facilitates hair growth. Based on our theory, we provide a roadmap for the development of a new class of drugs for the treatment of androgenetic alopecia.

    This study employs findings from social comparison research to investigate adolescents' comparisons with siblings with regard to parental treatment. The sibling comparison hypothesis was tested on a sample of 516 two-child families by examining whether gender, self-esteem, and emotionality-which have been found in previous research to moderate social comparison-also moderate sibling comparison as reflected by siblings' own evaluations of differential parental treatment. Results supported a moderating effect for self-esteem and emotionality but not gender. The sibling comparison process was further examined by using a structural equation model in which parenting toward each child was associated with the adjustment of that child and of the child's sibling. Evidence of the "sibling barricade" effect-that is, parenting toward one child being linked with opposite results on the child's sibling as on the target child-was found in a limited number of cases and interpreted as reflecting a sibling comparison process. For older siblings, emotionality and self-esteem moderated the sibling barricade effect but in the opposite direction as predicted. Results are discussed in terms of older siblings' increased sensitivity to parenting as well as the report of differential parenting reflecting the child's level of comfort and benign understanding of differential parenting, which buffers the child against environmental vicissitudes evoking sibling comparison processes.

    Mexico recently enacted drug policy reform to decriminalize possession of small amounts of illicit drugs and mandated that police refer identified substance users to drug treatment. However, the economic implications of drug treatment expansion are uncertain. We estimated the costs of opioid substitution therapy (OST) provision in Tijuana, Mexico, where opioid use and HIV are major public health concerns. We adopted an economic health care provider perspective and applied an ingredients-based micro-costing approach to quantify the average monthly cost of OST (methadone maintenance) provision at two providers (one private and one public) in Tijuana, Mexico. Costs were divided by type of input (capital, recurrent personnel and non-personnel). We defined "delivery cost" as all costs except for the methadone and compared total cost by type of methadone (powdered form or capsule). Cost data were obtained from interviews with senior staff and review of expenditure reports. Service provision data were obtained from activity logs and senior staff interviews. Outcomes were cost per OST contact and cost per person month of OST. We additionally collected information on patient charges for OST provision from published rates. The total cost per OST contact at the private and public sites was $3.12 and $5.90, respectively, corresponding to $95 and $179 per person month of OST. The costs of methadone delivery per OST contact were similar at both sites ($2.78 private and $3.46 public). However, cost of the methadone itself varied substantially ($0.34 per 80 mg dose [powder] at the private site and $2.44 per dose [capsule] at the public site). Patients were charged $1.93-$2.66 per methadone dose. The cost of OST provision in Mexico is consistent with other upper-middle income settings. However, evidenced-based (OST) drug treatment facilities in Mexico are still unaffordable to most people who inject drugs.

  4. Matching of Energy Provisions in Multihop Wireless Infra-Structures

    Full Text Available Recently there have been large advances in energy technologies for battery-operated systems, including green energy resources and high capacity batteries. The effective use of battery energy resources in wireless infrastructure networks to improve the versatility and reliability of wireless communications is an important issue. Emerging applications of smart cities, Internet of Things (IoT, and emergency responses highly rely on the basic communication network infrastructures that enable ubiquitous network connections. However, energy consumption by nodes in a wireless infrastructure network depends on the transmissions of other nodes in the network. Considering this inter-dependence is necessary to achieve efficient provision of energy in wireless networks. This paper studies the issue of energy provision for wireless relay nodes in Wireless Multihop Infrastructures (WMI assuming constraints on the total energy provision. We introduce a scheme of Energy Provision Matching (Matching-EP for WMI which optimizes energy provision based on matching of energy provision with estimates of differentiated position-dependent energy consumption by wireless nodes distributed in the network. The evaluation results show that Matching-EP with 4%–34% improvement in energy matching degree enables 10%–40% improvement of the network lifetime, and 5%–40% improvement of packet delivery compared with conventional WMI networks.

    ...there are reasons enough to warrant a coherent treatment of the main body of differential topology in the realm of Banach manifolds, which is at the same time correct and complete. This book fills the gap: whenever possible the manifolds treated are Banach manifolds with corners. Corners add to the complications and the authors have carefully fathomed the validity of all main results at corners. Even in finite dimensions some results at corners are more complete and better thought out here than elsewhere in the literature. The proofs are correct and with all details. I see this book as a reliable monograph of a well-defined subject; the possibility to fall back to it adds to the feeling of security when climbing in the more dangerous realms of infinite dimensional differential geometry.

    This study examined whether treatment response to stepped-care cognitive-behavioural treatment (CBT) is associated with changes in threat-related selective attention and its specific components in a large clinical sample of anxiety-disordered children. Ninety-one children with an anxiety disorder were included in the present study. Children received a standardized stepped-care CBT. Three treatment response groups were distinguished: initial responders (anxiety disorder free after phase one: child-focused CBT), secondary responders (anxiety disorder free after phase two: child-parent-focused CBT), and treatment non-responders. Treatment response was determined using a semi-structured clinical interview. Children performed a pictorial dot-probe task before and after stepped-care CBT (i.e., before phase one and after phase two CBT). Changes in selective attention to severely threatening pictures, but not to mildly threatening pictures, were significantly associated with treatment success. At pre-treatment assessment, initial responders selectively attended away from severely threatening pictures, whereas secondary responders selectively attended toward severely threatening pictures. After stepped-care CBT, initial and secondary responders did not show any selectivity in the attentional processing of severely threatening pictures. Treatment non-responders did not show any changes in selective attention due to CBT. Initial and secondary treatment responders showed a reduction of their predisposition to selectively attend away or toward severely threatening pictures, respectively. Treatment non-responders did not show any changes in selective attention. The pictorial dot-probe task can be considered a potentially valuable tool in assigning children to appropriate treatment formats as well as for monitoring changes in selective attention during the course of CBT.

    This study aimed to identify the imaging characteristics that can help differentiate intraparenchymal hemorrhage from benign contrast extravasation on post-procedural noncontrast CT scan in acute ischemic stroke patients after endovascular treatment. We reviewed the clinical and imaging records of all acute ischemic stroke patients who underwent endovascular treatment in two hospitals over a 3.5-year period. The immediate post-procedural CT scan was evaluated for the presence of hyperdense lesion(s). The average attenuation of the lesion(s) was measured. Intraparenchymal hemorrhage was defined as a persistent hyperdensity visualized on follow-up CT scan, 24 h or greater after the procedure. Of the 135 patients studied, 74 (55 %) patients had hyperdense lesion(s) on immediate post-procedural CT scan. Follow-up scans confirmed the diagnosis of intraparenchymal hemorrhage in 20 of these 74 patients. A receiver operating characteristic analysis showed that the average attenuation of the most hyperdense lesion can differentiate intraparenchymal hemorrhage from contrast extravasation with an area under the curve of 0.78 (p = 0.001). An average attenuation of <50 Hounsfield units (HU) in the most visually hyperattenuating hyperdense lesion had 100 % specificity and 56 % sensitivity for identification of contrast extravasations. Petechial hyperdensity was seen in 46/54 (85 %) patients with contrast extravasation versus 9/20 (45 %) patients with intraparenchymal hemorrhage on the immediate post-procedural CT scan (p < 0.001). An average attenuation <50 HU of the most hyperattenuating hyperdense parenchymal lesion on immediate post-procedural CT scan was very specific for differentiating contrast extravasation from intraparenchymal hemorrhage in acute ischemic stroke patients after endovascular treatment.

    Increasing the success rate of rotator cuff healing remains tremendous challenge. Among many approaches, the possibility of activating resident stem cells in situ, without the need to isolate them from biopsies, could represent valuable therapeutic strategy. Along this line, it has been recently demonstrated that lipoaspirate product, Lipogems, contains and produces growth-factors that may activate resident stem cells. In this study, human tendon stem cells (hTSCs) from the rotator cuff were cocultured in a transwell system with the Lipogems lipoaspirate product and compared to control untreated cells in terms of cell proliferation, morphology, stem cell marker and VEGF expression, and differentiation and migration capabilities. Results showed that the Lipogems product significantly increases the proliferation rate of hTSCs without altering their stemness and differentiation capability. Moreover, treated cells increase the expression of VEGF, which is crucial for the neovascularization of the tissue during the healing process. Overall, this study supports that directly activating hTSCs with the Lipogems lipoaspirate could represent a new practical therapeutic approach. In fact, obtaining a lipoaspirate is easier, safer, and more cost-effective than harvesting cells from tendon or bone marrow biopsies, expanding them in GMP facility and then reinjecting them in the patient.

    Full Text Available Increasing the success rate of rotator cuff healing remains tremendous challenge. Among many approaches, the possibility of activating resident stem cells in situ, without the need to isolate them from biopsies, could represent valuable therapeutic strategy. Along this line, it has been recently demonstrated that lipoaspirate product, Lipogems, contains and produces growth-factors that may activate resident stem cells. In this study, human tendon stem cells (hTSCs from the rotator cuff were cocultured in a transwell system with the Lipogems lipoaspirate product and compared to control untreated cells in terms of cell proliferation, morphology, stem cell marker and VEGF expression, and differentiation and migration capabilities. Results showed that the Lipogems product significantly increases the proliferation rate of hTSCs without altering their stemness and differentiation capability. Moreover, treated cells increase the expression of VEGF, which is crucial for the neovascularization of the tissue during the healing process. Overall, this study supports that directly activating hTSCs with the Lipogems lipoaspirate could represent a new practical therapeutic approach. In fact, obtaining a lipoaspirate is easier, safer, and more cost-effective than harvesting cells from tendon or bone marrow biopsies, expanding them in GMP facility and then reinjecting them in the patient.

    Full Text Available Pluripotent stem cells as the cells with a capacity for self-renewal and differentiation into various specificcell types have been highly regarded in regenerative medicine studies. To repair the eye disease damages, thedifferentiation into retinal pigment epithelial cells of pluripotent stem cells has gained great importance inrecent decades because the inappropriate function of these cells is the main cause of degenerative diseases suchas the age-related macular degeneration. Millions of people in the world suffer this disease.To restore the damaged cells and, finally, to improve the vision, numerous studies have been conducted on usingpluripotent stem cells, their differentiation into retinal pigment epithelial cells, and finally, their applicationin cell therapy. Based on this, many researchers have attempted to produce highly efficient retinal pigmentepithelial cells, such that they show a proper function after transplant, along with the host cells. In this reviewarticle, the importance and the role of pigment epithelial cells, as well as, the studies on the in vitro productionof these cells were examined

    Several studies targeting individuals with panic disorder have demonstrated that Cognitive-behavioral treatment (CST) is the psychological treatment of choice. CST interventions that include exposure to panic symptoms, along with cognitive restructuring. breathing retraining, and relaxation training are more effective than any of these components administered alone. Past studies have demonstrated the efficacy of imparting the above CBT components in the form of bibliotherapy (BT) ...

    To investigate the effects of rhythmic auditory stimulation (RAS) on gait patterns in comparison with changes after neurodevelopmental treatment (NDT/Bobath) in adults with cerebral palsy. A repeated-measures analysis between the pretreatment and posttreatment tests and a comparison study between groups. Human gait analysis laboratory. Twenty-eight cerebral palsy patients with bilateral spasticity participated in this study. The subjects were randomly allocated to either neurodevelopmental treatment (n = 13) or rhythmic auditory stimulation (n = 15). Gait training with rhythmic auditory stimulation or neurodevelopmental treatment was performed three sessions per week for three weeks. Temporal and kinematic data were analysed before and after the intervention. Rhythmic auditory stimulation was provided using a combination of a metronome beat set to the individual's cadence and rhythmic cueing from a live keyboard, while neurodevelopmental treatment was implemented following the traditional method. Temporal data, kinematic parameters and gait deviation index as a measure of overall gait pathology were assessed. Temporal gait measures revealed that rhythmic auditory stimulation significantly increased cadence, walking velocity, stride length, and step length (P rhythmic auditory stimulation (P rhythmic auditory stimulation (P rhythmic auditory stimulation showed aggravated maximal internal rotation in the transverse plane (P rhythmic auditory stimulation or neurodevelopmental treatment elicited differential effects on gait patterns in adults with cerebral palsy.

    Cognitive beliefs and affective responses to illness and treatment are known to independently predict health behaviours. The purpose of the current study is to assess the relative importance of four psychological domains – specifically, affective illness, cognitive illness, affective treatment and cognitive treatment – for predicting stroke and transient ischemic attack (TIA) survivors’ adherence to stroke prevention medications as well as their objective, categorised stroke risk. We assessed these domains among stroke/TIA survivors (n = 600), and conducted correlation and regression analyses with concurrent and prospective outcomes to determine the relative importance of each cognitive and affective domain for adherence and stroke risk. As hypothesised, patients’ affective treatment responses explained the greatest unique variance in baseline and six-month adherence reports (8 and 5%, respectively, of the variance in adherence, compared to 1–3% explained by other domains). Counter to hypotheses, patients’ cognitive illness beliefs explained the greatest unique variance in baseline and six-month objective categorised stroke risk (3 and 2%, respectively, compared to 0–1% explained by other domains). Results indicate that domain type (i.e. cognitive and affective) and domain referent (illness and treatment) may be differentially important for providers to assess when treating patients for stroke/TIA. More research is required to further distinguish between these domains and their relative importance for stroke prevention. PMID:25220292

    Helminth parasites induce a strong Th2 response, characterized by high levels of IgE and elevated signature cytokines such as IL-5. As many global deworming programmes are underway, there is concern that this might lead to emergence of Th1-mediated pathologies when the counterbalancing helminth-induced Th2 response is absent. Therefore, we assessed the effect of deworming on Th2-mediated responses in a household-clustered randomized controlled trial in Indonesia. Total plasma IgE and whole-blood IL-5 responses to mitogen phytohaemagglutinin (PHA) were measured in 1494 and 682 subjects, respectively, at baseline, 9 and 21 months after three-monthly single-dose treatment with albendazole or placebo. Anthelmintic treatment did not result in complete removal of helminth infections in the community. However, treatment significantly decreased IgE levels in albendazole- compared to placebo-treated subjects. IL-5 responses to PHA were not significantly affected by anthelmintic treatment and tended to increase in albendazole-treated subjects, indicating that intensive treatment of helminth parasites has different outcomes on B-cell (IgE levels) and T-cell (IL-5) responses. The data shows that 2 years of deworming can have differential effects on responses typified as Th2-mediated, which needs to be taken into account when examining the impact of helminths on noncommunicable diseases. © 2017 John Wiley & Sons Ltd.

    Although animal models based on amphetamine (AMPH) or phencyclidine (PCP) treatment have been used extensively to study the neurobiological and behavioral characteristics of schizophrenia, there are conflicting reports regarding their validity in modeling the negative symptoms and cognitive deficits of schizophrenia. The present study examined how acute AMPH or PCP treatment (Experiment 1) and withdrawal from repeated AMPH treatment (Experiment 2) or PCP treatment (Experiment 3) affects social behavior and social recognition memory in male Sprague-Dawley rats. Each subject was tested on two consecutive days. On the first day, the rats were tested four times (5 min/each) at 10-min intervals with the same partner rat (termed "AAAA" day). One day later, the rats were tested with the previous partner in the first three sessions and with a new partner rat in the final session (termed "AAAB" day). The results show that acute AMPH treatment (1.5 mg/kg, sc) significantly reduced the time spent on social interaction, but did not affect social recognition on the first day. Acute AMPH only disrupted social recognition on the second day of drug testing. In contrast, acute PCP treatment (2.0 mg/kg, sc) had no effect on time spent on social interaction, but did significantly disrupt social recognition on both days. Withdrawal from repeated AMPH (3.0 mg/kg/day for 7 days, ip) or PCP (5.0 mg/kg/twice daily for 7 days, ip) treatment did not affect social interaction or social recognition, indicating a lack of long-term detrimental effect of repeated AMPH or PCP treatment. These results suggest that acute AMPH treatment at a low dose (1.5 mg/kg) may be useful in modeling social withdrawal symptoms of schizophrenia, whereas acute PCP treatment at a similar dose range (2.0 mg/kg) may be useful in modeling the social cognitive deficit of schizophrenia. © 2012 The Institute of Psychology, Chinese Academy of Sciences and Blackwell Publishing Asia Pty Ltd.

    The forced swim test (FST) is the most widely used model for assessing potential antidepressant activity in rodents following acute or short-term treatment. However, few studies have compared the effects of short- and long-term antidepressant treatment on behaviors in the test, despite the need to treat patients chronically to produce clinical effects. The current studies examined whether antidepressants from different classes produce different behavioral effects following short-term treatment and whether such effects change following administration for a longer duration. The effects of administering short-term (3 days) and long-term (14 days) treatments of antidepressants from three different chemical classes with distinct mechanisms of action via osmotic minipump were examined: the selective norepinephrine reuptake inhibitor reboxetine (10 and 60 mg kg(-1) day(-1)), the selective serotonin reuptake inhibitor fluoxetine (2.5 and 15 mg kg(-1) day(-1)), and the reversible inhibitor of monoamine oxidase moclobemide (2.5 and 15 mg kg(-1) day(-1)). All testing was carried out in a 15-min test with no preswim session in order to negate any confounding aspect of an induction procedure. The majority of antidepressant-sensitive behavioral changes were observed in the first 5 min of the test. The low dose of reboxetine failed to alter behavior in the test after 3 days but significantly decreased immobility and increased climbing behavior following administration for 14 days, whereas the high dose of reboxetine was equally effective following 3 and 14 days of treatment. In a similar fashion, the low dose of fluoxetine failed to alter behavior in the test following 3 days, but showed an augmented response on immobility and increased swimming following administration for 14 days. The high dose of fluoxetine was slightly more effective at reducing immobility following administration for 14 days than 3 days. The low dose of moclobemide decreased immobility and increased climbing

    The effect of prior heat treatment on thermal enhancement of radiodermatitis was investigated in the ear of the mouse. Ears were heated by immersion in hot water. A priming treatment of 43.5 0 C for 30 min (H) was given at various times before a second combined treatment of hypethermia at 43.5 0 C (h) given immediately before (hX) or after (Xh) a dose of X rays (X). The effect of H was measured in two ways. The heating time h, required to cause a given enhancement of radiodermatitis was estimated by fixing X and varying the duration of h. The thermal enhancement ratio, defined as the dose of X rays alone divided by the dose of X rays with heat required to cause a given reaction, was measured by fixing h and varying X. The priming treatment H reduced the skin response to hX. This effect was such that at 24 to 96 hr after H, the heating time h, had to be increased to about 1.5 times that required without prior hyperthermia. In contrast, the priming treatment had no effect on the response to Xh

    Chronic lymphocytic leukemia (CLL) is a monoclonal disorder, characterized by a progressive proliferation of functionally incompetent B lymphocytes. There is increased evidence of association between CLL and skin cancers, including the uncommon Merkel cell carcinoma (MCC). A case report of an 84-year old male, who presented with an aggressively recurrent form of MCC on the lower lip, on the background of an 8-year history of untreated CLL. During the recurrences of MCC, coexisting regional lymphadenopathy, posed a problem in the differential diagnosis and treatment of lymph node involvement. Histopathology and immunoistochemistry showed that submandibular lymphadenopathy coexisting with the second recurrence of MCC, was due to B-cell small lymphocytic lymphoma. The subsequent and more aggressive recurrence of the skin tumor had involved the superficial and deep cervical lymph nodes. Surgical excision followed by involved field radiation therapy has been proven effective for both malignancies. MCC has a high incidence of regional lymphadenopathy at presentation (12–45%) and even when it arises on the background of chronic leucemia, lymphadenopathy at presentation should be managed agressively with elective lymph node dissection. We overview the postulated correlation between Merkel tumor and CCL, the differential diagnosis of regional lymphadenopathy during the recurrences of the skin tumor and the strategies of treatment

    Zhu, Bofan

    Biocompatible scaffolds mimicking the locally aligned fibrous structure of native extracellular matrix (ECM) are in high demand in tissue engineering. In this thesis research, unidirectionally aligned fibers were generated via a home-built electrospinning system. Collagen type I, as a major ECM component, was chosen in this study due to its support of cell proliferation and promotion of neuroectodermal commitment in stem cell differentiation. Synthetic dragline silk proteins, as biopolymers with remarkable tensile strength and superior elasticity, were also used as a model material. Good alignment, controllable fiber size and morphology, as well as a desirable deposition density of fibers were achieved via the optimization of solution and electrospinning parameters. The incorporation of silk proteins into collagen was found to significantly enhance mechanical properties and stability of electrospun fibers. Glutaraldehyde (GA) vapor post-treatment was demonstrated as a simple and effective way to tune the properties of collagen/silk fibers without changing their chemical composition. With 6-12 hours GA treatment, electrospun collagen/silk fibers were not only biocompatible, but could also effectively induce the polarization and neural commitment of stem cells, which were optimized on collagen rich fibers due to the unique combination of biochemical and biophysical cues imposed to cells. Taken together, electrospun collagen rich composite fibers are mechanically strong, stable and provide excellent cell adhesion. The unidirectionally aligned fibers can accelerate neural differentiation of stem cells, representing a promising therapy for neural tissue degenerative diseases and nerve injuries.

    The plasma membrane (PM) forms a barrier between a plant cell and its environment. Proteins at this subcellular location play diverse and complex roles, including perception of extracellular signals to coordinate cellular changes. Analyses of PM proteins, however, are often limited by the relatively low abundance of these proteins in the total cellular protein pool. Techniques traditionally used for enrichment of PM proteins are time consuming, tedious, and require extensive optimization. Here, we provide a simple and reproducible enrichment procedure for PM proteins from Arabidopsis thaliana seedlings starting from total microsomal membranes isolated by differential centrifugation. To enrich for PM proteins, total microsomes are treated with the nonionic detergent Brij-58 to decrease the abundance of contaminating organellar proteins. This protocol combined with the genetic resources available in Arabidopsis provides a powerful tool that will enhance our understanding of proteins at the PM.

    Purpose: It has been reported recently that the change of CT number (CTN) during and after radiation therapy (RT) may be used to assess RT response. The purpose of this work is to develop a tool to automatically segment the regions with differentiating CTN and/or with change of CTN in a series of CTs. Methods: A software tool was developed to identify regions with differentiating CTN using K-mean Cluster of CT numbers and to automatically delineate these regions using convex hull enclosing method. Pre- and Post-RT CT, PET, or MRI images acquired for sample lung and pancreatic cancer cases were used to test the software tool. K-mean cluster of CT numbers within the gross tumor volumes (GTVs) delineated based on PET SUV (standard uptake value of fludeoxyglucose) and/or MRI ADC (apparent diffusion coefficient) map was analyzed. The cluster centers with higher value were considered as active tumor volumes (ATV). The convex hull contours enclosing preset clusters were used to delineate these ATVs with color washed displays. The CTN defined ATVs were compared with the SUV- or ADC-defined ATVs. Results: CTN stability of the CT scanner used to acquire the CTs in this work is less than 1.5 Hounsfield Unit (HU) variation annually. K-mean cluster centers in the GTV have difference of ∼20 HU, much larger than variation due to CTN stability, for the lung cancer cases studied. The dice coefficient between the ATVs delineated based on convex hull enclosure of high CTN centers and the PET defined GTVs based on SUV cutoff value of 2.5 was 90(±5)%. Conclusion: A software tool was developed using K-mean cluster and convex hull contour to automatically segment high CTN regions which may not be identifiable using a simple threshold method. These CTN regions were reasonably overlapped with the PET or MRI defined GTVs

    Full text: Low iodine diet (LID) is accepted as an adjuvant to post-thyroidectomy radioiodine therapy of differentiated thyroid cancer since it is held to enhance radioiodine uptake in thyroid remnants and thyroid cancer tissue. However, in the few clinical investigations performed only an indirect and weak evidence of a positive effect of the LID has been demonstrated. Also we had discouraging experience in the application of a strict LID using the same design as in the present study. We therefore decided to investigate the effect of a diet low in iodine as well as in goitrogens (LILGD). Methods: Six patients with differentiated thyroid cancer entered the study and they were their own control. After thyroid hormone withdrawal (TSH > 30 m U/L) and on regular diet a diagnostic whole body scan was performed 24 h after administration of 50 MBq (1,4 mCi) 123 I. The day following diagnostic scan the patients were put on LILGD for 4 days prior and two days after radioiodine therapy. In LILGD beverages, fruits and vegetables containing flavonoids, glucosinolates, cyanides and thiocyanates were avoided and spices and smoking prohibited. Therapeutic radioiodine was administered one week after diagnostic procedures and in the morning after over-night fasting with an activity range of 3,7-5,4 GBq (100 -150 mCi) 131 I. A 24-h therapeutic whole body scan and calculations of percentage uptake U(24) were performed. Diagnostic (basal) D U(24)% and subsequent therapeutic T U(24)% uptake were compared and expressed as therapeutic/diagnostic uptake ratios T/D U(24). Results: A significant increase in therapeutic versus diagnostic uptake T/D U(24) was observed (mean 2,53, median 2,30, range 1,40 - 4,46, p 131 I uptake in radio-ablation of normal and thyroid cancer tissue.

    This article extends the framework of Le Grand (2003, 2010) to encompass responsiveness, and the main argument is that the combination of employee motivation, user capacity, and models of public service provision potentially has serious implications for responsiveness across service areas. Although...... research on employee motivation thrives, especially in the public service motivation (PSM) literature, few studies have investigated user capacity empirically, and we know little about the combination of PSM, user capacity and models of service provision. Analyzing four central service areas (day care......, schools, hospitals, and universities), we find variations in both user capacity and PSM. Taking this variation as a point of departure we discuss what implications different combinations of employee motivation, user capacity, and models of public service provision may have for responsiveness....

    What was the impact on access to assisted reproductive technology (ART) treatment by different socioeconomic status (SES) groups after the introduction of a policy that increased patient out-of-pocket costs? After the introduction of a policy that increased out-of-pocket costs in Australia, all SES groups experienced a similar percentage reduction in fresh ART cycles per 1000 women of reproductive age. Higher SES groups experienced a progressively greater reduction in absolute numbers of fresh ART cycles due to existing higher levels of utilization. Australia has supportive public funding arrangements for ARTs. Policies that substantially increase out-of-pocket costs for ART treatment create financial barriers to access and an overall reduction in utilization. Data from the USA suggests that disparities exist in access to ART treatment based on ethnicity, education level and income. Time series analysis of utilization of ART, intrauterine insemination (IUI) and clomiphene citrate by women from varying SES groups before and after the introduction of a change in the level of public funding for ART. Women undertaking fertility treatment in Australia between 2007 and 2010. Women from higher SES quintiles use more ART treatment than those in lower SES quintiles, which likely reflects a greater ability to pay for treatment and a greater need for ART treatment as indicated by the trend to later childbearing. In 2009, 10.13 and 5.17 fresh ART cycles per 1000 women of reproductive age were performed in women in the highest and lowest SES quintiles respectively. In the 12 months after the introduction of a policy that increased out-of-pocket costs from ∼$1500 Australian dollars (€1000) to ∼$2500 (€1670) for a fresh IVF cycle, there was a 21-25% reduction in fresh ART cycles across all SES quintiles. The absolute reduction in fresh ART cycles in the highest SES quintile was double that in the lowest SES quintile. In this study, SES was based on the average relative

    Although youth living with behaviorally acquired HIV (YLWH) are at risk for cognitive impairments, the relationship of impairments to HIV and potential to improve with antiretroviral therapy (ART) are unclear. This prospective observational study was designed to examine the impact of initiation and timing of ART on neurocognitive functioning in YLWH in the Adolescent Medicine Trials Network for HIV/AIDS Interventions. Treatment naïve YLWH age 18-24 completed baseline and four additional assessments of attention/working memory, complex executive, and motor functioning over 3 years. Group 1 co-enrolled in an early ART initiation study and initiated ART at enrollment CD4 >350 (n = 56); group 2 had CD4 >350 and were not initiating ART (n = 66); group 3 initiated ART with CD4 treatment guidelines at the time. Treatment was de-intensified to boosted protease inhibitor monotherapy at 48 weeks for those in group 1 with suppressed viral load. Covariates included demographic, behavioral, and medical history variables. Analyses used hierarchical linear modeling. All groups showed improved performance with peak at 96 weeks in all three functional domains. Trajectories of change were not significantly associated with treatment, timing of treatment initiation, or ART de-intensification. Demographic variables and comorbidities were associated with baseline functioning but did not directly interact with change over time. In conclusion, YLWH showed improvement in neurocognitive functioning over time that may be related to practice effects and nonspecific impact of study participation. Neither improvement nor decline in functioning was associated with timing of ART initiation or therapy de-intensification.

    Reduced conception rate (CR) during the hot summer and subsequent autumn is a well-documented phenomenon. Intensive use of cooling systems can improve summer and autumn reproductive performance, but is unable to increase CR to winter and spring levels. We examined whether combined hormonal treatments--to increase follicular turnover before artificial insemination (AI) and progesterone supplementation post-AI--might improve fertility of cooled cows during the summer and autumn. The experiment was conducted from July to November in 3 commercial herds in Israel and included 707 Holstein cows at 50 to 60 d in milk (DIM). Cows were hormonally treated to induce 2 consecutive 9-d cycles, with GnRH administration followed by PGF2α injection 7 d later, followed by an intravaginal insert containing progesterone on d 5 ± 1 post-AI for 14 d. Both untreated controls (n=376) and treated cows (n=331) were inseminated following estrus, and pregnancy was determined by palpation 42 to 50 d post-AI. First-AI CR data revealed a positive interaction between treatment and cows previously diagnosed with postpartum uterine disease [odds ratio (OR) 2.24]. Interaction between treatment and low body condition score tended to increase the probability of first-AI CR (OR 1.95) and increased pregnancy rate at 90 DIM (OR 2.50) and at 120 DIM (OR 1.77). Low milk production increased the probability of being detected in estrus at the end of synchronization within treated cows (OR 1.67), and interacted with treatment to increase probability of pregnancy at 90 DIM (OR 2.39) relative to control counterparts. It is suggested that when administered with efficient cooling, combined hormonal treatment in specific subgroups of cows, that is, those previously diagnosed with postpartum uterine disease or those with low body condition score or low milk yield might improve fertility during the summer and autumn. Integration of such an approach into reproductive management during the hot seasons might improve

    This study aimed to investigate whether beneficial effects of thyroid hormones are comparable to those provided by the aerobic exercise training, to verify its applicability as a therapeutic alternative to reverse the pathological cardiac remodeling post-infarction. Male rats were divided into SHAM-operated (SHAM), myocardial infarction (MI), MI subjected to exercise training (MIE), and MI who received T3 and T4 treatment (MIH) (n = 8/group). MI, MIE and MIH groups underwent an infarction surgery while SHAM was SHAM-operated. One-week post-surgery, MIE and MIH groups started the exercise training protocol (moderate intensity on treadmill), or the T3 (1.2 μg/100 g/day) and T4 (4.8 μg/100 g/day) hormones treatment by gavage, respectively, meanwhile SHAM and MI had no intervention for 9 weeks. The groups were accompanied until 74 days after surgery, when all animals were anesthetized, left ventricle echocardiography and femoral catheterization were performed, followed by euthanasia and left ventricle collection for morphological, oxidative stress, and intracellular kinases expression analysis. Thyroid hormones treatment was more effective in cardiac dilation and infarction area reduction, while exercise training provided more protection against fibrosis. Thyroid hormones treatment increased the lipoperoxidation and decreased GSHPx activity as compared to MI group, increased the t-Akt2 expression as compared to SHAM group, and increased the vascular parasympathetic drive. Thyroid hormones treatment provided differential benefits on the LV function and autonomic modulation as compared to the exercise training. Nevertheless, the redox unbalance induced by thyroid hormones highlights the importance of more studies targeting the ideal duration of this treatment. Copyright © 2018 Elsevier Inc.

    Production of proteolytic enzymes by human fibroblasts in the process of transformation was investigated. The cells used were normal human fibroblasts (KSM-6) and their in vitro counterparts transformed by treatment with 60 Co gamma rays (KMST-6). Cells seeded by treatment with EDTA were cultured in a serum free medium. Proteolytic enzymes in the culture medium of cells were assayed using a synthetic substrate, N-α-(p-tosyl)-L-arginine ( 3 H) methyl ester hydrochloride. The transformed cells (KMST-6) produced a larger amount of enzymes than normal cells (KMS-6). The enzyme production in both cell lines was high in the exponential growth stage and then decreased as the cells reached confluency. The proteolytic enzymes produced by these cells were trypsin- and thrombin-like enzymes. Cell growth of KMST-6 or KMS-6 was not inhibited by the addition of protease inhibitors to the culture medium.

    OBJECTIVES: To study benefits and skeletal side effects of carefully monitored prednisolone treatment in patients with active rheumatoid arthritis. METHODS: One hundred and two patients with active rheumatoid arthritis were randomly allocated to treatment with disease modifying anti......-inflammatory drug (DMARD) alone or DMARD and prednisolone in a one year follow up study. Prednisolone was given in a dose regimen adapted to the disease activity of the individual patient. The mean dose was 6 mg and the mean cumulated dose was 2160 mg. Patients were followed up with disease activity parameters......, radiograph of the hands (Larsen score), and bone mineral density (BMD) of the lumbar spine, distal forearm and hand. At one year 26 patients had withdrawn from the investigation leaving 76 patients for evaluation. RESULTS: The results showed that disease activity in the prednisolone treated group was reduced...

  7. HIRSCHSPRUNG'S DISEASE—The Clinical Differentiation and Treatment of Children with Hirschsprung's Disease and Pseudo-Hirschsprung's Disease

    Hirschsprung's disease is marked by constipation from the time of birth, with the development, if uncorrected, of a protuberant abdomen and flared costal margins. The rectal ampulla is empty and the abdomen is filled with fecal masses. Pain is not prominent. Flatus is passed in large amounts. Encopresis does not occur. Barium enema shows the characteristic narrowed distal rectal segment and biopsy of the rectum shows absence of the ganglion cells of the myenteric plexus. Treatment is operative resection of the distal narrow segment and a primary anastomosis. Hirschsprung's disease may be mimicked in children with: 1. Psychogenic constipation—pseudo-Hirschsprung's disease. Unlike Hirschsprung's disease, symptoms do not appear at birth, encopresis is common, and the barium enema shows no narrow distal segment. 2. Mental retardation and cerebral defect. 3. Corrected imperforate anus—on the basis of stenosis, imperfect innervation or poor habit training. 4. Cretinism—with severe constipation and intestinal dilatation perhaps the presenting symptoms. Treatment of these four groups of children with severe constipation not due to Hirschsprung's disease is: For Group 1, open discussion with parent and child. Assumption by the physician of full control of the details of treatment, and relegation of parent to the role of the physician's agent in following the prescribed regimen. For Group 2, an enema regimen. Whereas fairly rapid restoration (and then persistence) of normal bowel habit can be expected in Group 1, the basic defects in Group 2 may require indefinite continuation of treatment. For Group 3, regular enema regimen, in the less severe cases—one identical with that used in Group 1, and dilatation of strictures or anoplasty. In Group 4, thyroid hormone therapy relieves the constipation of hypothyroidism and causes reversion of radiographic changes in the colon and rectum. PMID:13561108

    Estrogen levels in rats are positively correlated with enhanced memory function and hippocampal dendritic spine density. There is much less work on the long-term effects of estradiol manipulation in preadolescent rats. The present work examined how injections of estradiol during postnatal days 19-22 (p19-22; preadolescence) affected water maze performance and hippocampal phosphorylated ERK labeling. To investigate this, half of the estradiol- and vehicle-treated female rats were trained on a water maze task 24h after the end of estradiol treatment (p23-27) while the other half was not trained. All female rats were tested on the water maze from p40 to p44 (adolescence) and hippocampal pERK1/2 labeling was assessed as a putative marker of neuronal plasticity. During adolescence, preadolescent-trained groups showed lower latencies than groups without preadolescent training. Retention data revealed lower latencies in both estradiol groups, whether preadolescent trained or not. Immunohistochemical detection of hippocampal pERK1/2 revealed elevations in granule cell labeling associated with the preadolescent trained groups and reductions in CA1 labeling associated with estradiol treatment. These results show a latent beneficial effect of preadolescent estradiol treatment on adolescent spatial performance and suggest an organizational effect of prepubescent exogenously applied estradiol.

    On treatment with 8-methoxypsoralen plus near uv light, an excision (uvrB/sup -/) strain of Escherichia coli showed about 3- and 10 times higher sensitivities to killing and mutation, respectively, than its parental strain. On re-irradiation with near uv in the absence of unbound psoralen, the uvrB/sup -/ strain pretreated with psoralen plus near uv showed a decrease in both survival and mutation. After treatment with psoralen plus near uv, re-irradiation of T7DNA in the absence of unbound psoralen caused an increase in the cross-linked fraction with an equivalent decrease in the non-cross-linked fraction. From these and previous results, it is concluded that monoadducts produced by treatment with psoralen plus near uv are converted to cross-links by further irradiation and that, in E.coli, monoadducts are responsible for the mutation induced by psoralen-plus-light whereas cross-links are the major cause of its lethal action.

    Full Text Available Timothy S Leung,1 Ernest H Law2 1Faculty of Pharmaceutical Sciences, University of British Columbia, Vancouver, BC, Canada; 2Department of Pharmacy Systems, Outcomes and Policy, College of Pharmacy, University of Illinois at Chicago, Chicago, IL, USA Abstract: Venous thromboembolism includes deep vein thrombosis and pulmonary embolism and is a serious medical condition that requires anticoagulation as part of treatment. Currently, standard therapy consists of parenteral anticoagulation followed by a vitamin K antagonist (VKA. The pharmacokinetic and pharmacodynamic profiles of the direct oral anticoagulants (DOACs differ from VKAs, which overcome some of the limitations of VKAs and have practical implications on their use in clinical situations. Dabigatran is a prodrug that undergoes primarily renal elimination and does not affect cytochrome P450 enzymes. Assays to quantify the degree of anticoagulation and the therapeutic level of DOAC are either unavailable for routine clinical use or require specific calibration. Routine monitoring of DOACs is not recommended at this time. Dabigatran, rivaroxaban, and apixaban are DOACs that have been studied for treatment of venous thromboembolism. Clinical trials comparing DOACs with standard therapy have shown them to be non-inferior for acute and extended therapy. Each DOAC has a unique benefit and harm profile that should be considered prior to use. The distinguishing characteristics of dabigatran include a requirement of parenteral anticoagulation prior to acute treatment, clinical trial results comparing it with a VKA for extended treatment, association with upper gastrointestinal adverse events, and increased risk of gastrointestinal bleed. Rivaroxaban is the only DOAC that has once-daily dosing while apixaban is the only DOAC that has lower risk of overall, major, and gastrointestinal bleeding compared with VKA. A common drawback of DOACs is the lack of an available reversal agent. Clinical trials of

  12. Opioid and GABAB receptors differentially couple to an adenylyl cyclase/protein kinase A downstream effector after chronic morphine treatment.

    Full Text Available Opioids are intensely addictive, and cessation of their chronic use is associated with a highly aversive withdrawal syndrome. A cellular hallmark of withdrawal is an opioid sensitive protein kinase A-dependent increase in GABA transporter-1 (GAT-1 currents in periaqueductal gray (PAG neurons. Elevated GAT-1 activity directly increases GABAergic neuronal excitability and synaptic GABA release, which will enhance GABAergic inhibition of PAG output neurons. This reduced activity of PAG output neurons to several brain regions, including the hypothalamus and medulla, contributes to many of the PAG-mediated signs of opioid withdrawal. The GABAB receptor agonist baclofen reduces some of the PAG mediated signs of opioid withdrawal. Like the opioid receptors the GABAB receptor is a Gi/Go coupled G-protein coupled receptor. This suggests it could be modulating GAT-1 activity in PAG neurons through its inhibition of the adenylyl cyclase/protein kinase A pathway. Opioid modulation of the GAT-1 activity can be detected by changes in the reversal potential of opioid membrane currents. We found that when opioids are reducing the GAT-1 cation conductance and increasing the GIRK conductance the opioid agonist reversal potential is much more negative than Ek. Using this approach for GABAB receptors we show that the GABAB receptor agonist, baclofen, does not couple to inhibition of GAT-1 currents during opioid withdrawal. It is possible this differential signaling of the two Gi/Go coupled G-protein coupled receptors is due to the strong compartmentalization of the GABAB receptor that does not favor signaling to the adenylyl cyclase/protein kinase A/GAT-1 pathway. This highlights the importance of studying the effects of G-protein coupled receptors in native tissue with endogenous G-protein coupled receptors and the full complement of relevant proteins and signaling molecules. This study suggests that baclofen reduces opioid withdrawal symptoms through a non-GAT-1

    Fractional Er:YAG minimizes the risk associated with skin ablation. Infrared diode laser and radiofrequency have suggested comparable improvements in acne scar. We compared the clinical efficacy of Er:YAG laser and bipolar radiofrequency combined with diode laser (BRDL) for the treatment of acne scars. Moreover, acute molecular changes of cytokine profile associated with wound healing have been evaluated to suggest mechanisms of improvement of acne scar. Twenty-four subjects with mild-to-moderate acne scars were treated in a split-face manner with Er:YAG and BRDL, with two treatment sessions, 4 weeks apart. Objective and subjective assessments were done at baseline, 1, 3, 7 days after each treatment and 4 weeks after last treatment. Skin biopsy specimens were obtained at baseline, 1, 3, 7, 28 days after one session of treatment for investigation of molecular profile of acute skin changes by laser treatment. Investigator's Global Assessment representing the improvement degree shows 2.1 (50%) in fractional Er:YAG and 1.2 (25%) in BRDL. Er:YAG induced the later and higher peak expression of TGFβs and collagenases, whereas BRDL induced earlier and lower expression of TGFβ and collagenases, relatively. PPARγ dropped rapidly after a peak in Er:YAG-treated side, which is associated with tissue inhibitor of metalloproteinase (TIMP) expression. We observed higher expression of TIMP after Er:YAG treatment compared with BRDL by immunohistochemistry, which may be associated with the expression of upregulation of collagen fibers. The superior efficacy of Er:YAG to BRDL in the treatment of acne scars may be associated with higher expression of collagen which is associated with differential expression of TGFβs, collagenases, PPARγ, and TIMP.

  15. Diagnosis and treatment of differentiated thyroid cancer (remains, recurrences and metastases) with "1"3"1I

    International Nuclear Information System (INIS)

    Sánchez, V.

    2016-01-01

    Thyroid cancer is the most common endocrine cancer. The incidence worldwide has increased exponentially at the expense of papillary type tumors. In recent years emerged the concept that a patient with low risk of mortality may have a high risk of recurrence of the disease, so the classification according to the risk of recurrence is one of the most important steps to establish what will be the probability that the patient is in remission or present structural disease tracking. The American Joint Committee on Cancer (AJCC) has designated a staging system based on the TNM classification, which allows good mortality risk stratification. It must keep track short and long term patient, being that approximately 30% of all cases have recurrencies. The use of "1"3"1I falls into one of three categories: a) ablation, b) adjuvant and c) therapeutic. The diagnostic body scan provides information on the existence of iodine avid thyroid tissue, although it is not recommended for routine, can be performed in special cases. The postoperative body scan is usually performed to visualize metastasis previously not found. Persistent disease diagnosis is made by imaging studies such as ultrasound or body scan. The preferred treatment management of metastatic distant disease (in order), is surgical excision, iodine therapy, radiotherapy, observation and experimental studies. It is noteworthy that iodine treatment has harmful effects (early and late), so it should be applied only if you will gain a clear benefit for the patient. (author) [es

    Problems affecting the vaginal tract in diabetic women are very often neglected. The efficacy and safety of three gynecological treatments in diabetic women have been assessed. A single-blind randomized progressive trial on 48 diabetic women affected by vaginal dryness, dyspareunia, and recurrent Candida infections was carried out. The ICIQ Vaginal Symptoms (ICIQ-VS) questionnaire was administered. The analysis of the parameters of ICIQ-VS questionnaire among the three groups showed significant difference only for "dragging pain" (p = 0.0 19) and "soreness" (p = 0.028). In all groups and for all parameters of the questionnaire, improvement of symptoms was observed. In particular, in Group 1 for all symptoms a highly significant difference was observed, to support the already known benefits of the products and of the proposed combination. Significant improvement was also observed in Group 2. The proposed treatment with DermoXEN® Ultracalming Special for diabetics and DermoXEN® Vitexyl vaginal gel exert effective moisturizing and soothing action. Indeed, the aforementioned products have been proven effective for the main gynecological problems of diabetic women.

    In the past decades, the clinical use of dopamine agonists has expanded from adjunct therapy in patients with a deteriorating response to L-3,4-dihydroxyphenylalanine (L-DOPA) to monotherapy for the treatment of early PD. Dopamine agonists provide their antiparkinsonian benefit through stimulation of brain postsynaptic type 2 dopamine receptors that exert their effect through classical cAMP-dependent mechanisms, as well as cAMP-independent cellular signaling cascades, including the Akt/glycogen synthase kinase 3 (GSK3) pathway. Alterations of Akt/GSK3 have been observed and may contribute to the neurodegenerative processes and the development of L-DOPA-induced dyskinesia. The effects L-DOPA and quinpirole, a dopamine agonist, on the two key regulatory kinases, Akt and GSK3, were evaluated in neuroblastoma cell line. L-DOPA and dopamine agonist dose-dependently and differentially modulated Akt and GSK3 expression and phosphorylation when added alone or combined. The combined treatment inverted or potentiated the modulatory properties of the single compound. The drug- and concentration-dependent balance of dopamine receptor stimulation over auto-oxidation may distinctively modulate GSK3 isoforms and Akt. Our results indicate that particular attention must be given to drug concentration and combination when multiple therapies are applied for the clinical treatment of PD patients.

    Prostate cancer can transform from androgen-responsive to an androgen-independent phenotype. The mechanism responsible for the transformation remains unclear. We studied the effects of an epigenetic modulator, phenethyl isothiocyanate (PEITC), on the androgen-responsive LNCaP cells. After treatment with PEITC, floating spheres were formed with characteristics of prostate cancer stem cells (PCSC). These spheres were capable of self-renewal in media with and without androgen. They have been maintained in both types of media as long term cultures. Upon androgen deprivation, the adherent spheres differentiated to neuroendocrine cells (NEC) with decreased proliferation, expression of androgen receptor, and PSA. NEC reverse differentiated to spheres when androgen was replenished. The sphere cells expressed surface marker CD44 and had enhanced histone H3K4 acetylation, DNMT1 down-regulation and GSTP1 activation. We hypothesize that PEITC-mediated alteration in epigenomics of LNCaP cells may give rise to sphere cells, whereas reversible androgenomic alterations govern the shuttling between sphere PCSC and progeny NEC. Our findings identify unrecognized properties of prostate cancer sphere cells with multi-potential plasticity. This system will facilitate development of novel therapeutic agents and allow further exploration into epigenomics and androgenomics governing the transformation to hormone refractory prostate cancer.

    The purpose of this study was to evaluate if short-term serum thyroglobulin (Tg) elevation after radioiodine administration can predict successful radioiodine remnant ablation (RRA) and whether comparable RRA effectiveness is exhibited between a group administered with recombinant human thyrotropin (rhTSH) and a group experiencing thyroid hormone withdrawal (THW), in preparation for RRA. A retrospective chart review was performed on 39 patients in the rhTSH group and 46 patients in the THW group. They were treated for differentiated thyroid carcinoma by total or near total thyroidectomy, and referred for RRA between 2003 and 2006 (the rhTSH group) and between January and June of 2006 (the THW group). They were assessed for serum Tg levels just before I-131 administration (TgD0), reassessed 9 days later (TgD9), and again 6-12 months later. RRA was successful in 64 (37 from the THW group and 27 from the rhTSH group) of the total 85 patients. The success rates of RRA had no statistically significant differences between the two groups. In both groups, TgD9/TgD0 values were significantly higher in the RRA success group (the rhTSH group; P=0.03, the THW group; P=0.04). By combining cutoff values of TgD0 and TgD9/TgD0, the successful RRA value was determined to be 96.7% (29/30) with TgD0≤5.28 ng/mL and TgD9/TgD0>4.37 in both groups (the rhTSH group; 100% (16/16), the THW group; 92.9% (13/14)). Using logistic multivariate analysis, only TgD0 was independently associated with successful RRA. We may predict successful ablation by evaluating short-term serum Tg elevation after I-131 administration for RRA, in both rhTSH and THW patients

    Sodium butyrate (NaBu) and sodium 4-phenylbutyrate (4PBA) have promising futures in cancer treatment; however, their underlying molecular mechanisms are not clearly understood. Here, we show A549 cell death induced by NaBu and 4PBA are not the same. NaBu treatment induces a significantly higher level of A549 cell death than 4PBA. A gene expression microarray identified more than 5000 transcripts that were altered (>1.5-fold) in NaBu-treated A549 cells, but fewer than 2000 transcripts that were altered in 4PBA. Moreover, more than 100 cell cycle-associated genes were greatly repressed by NaBu, but slightly repressed by 4PBA; few genes were significantly upregulated only in 4PBA-treated cells. Gene expression was further validated by other experiments. Additionally, A549 cells that were treated with these showed changes in glucose consumption, caspase 3/7 activation and histone modifications, as well as enhanced mitochondrial superoxide production. TXNIP was strongly induced by NaBu (30- to 40-fold mRNA) but was only slightly induced by 4PBA (two to fivefold) in A549 cells. TXNIP knockdown by shRNA in A549 cells significantly attenuated caspase 3/7 activation and restored cell viability, while TXNIP overexpression significantly increased caspase 3/7 activation and cell death only in NaBu-treated cells. Moreover, TXNIP also regulated NaBu- but not 4PBA-induced H4K5 acetylation and H3K4 trimethylation, possibly by increasing WDR5 expression. Finally, we demonstrated that 4PBA induced a mitochondrial superoxide-associated cell death, while NaBu did so mainly through a TXNIP-mediated pathway. The above data might benefit the future clinic application. © 2016 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    Sodium Iodide-131 is administrated for treatment of hyperthyroidism and thyroid cancer. Iodine-131 has multiple routs of excretion (urine, saliva, sweat, milk, feces, exhalation) from the body. Patients receiving Sodium Iodide-131 therapy exposes other persons and the environment to unwanted radiation and contamination. The major sources of radiation dose from administration of Iodine-131 is external radiation , also there is a potential for exposure via contamination.Precautions are necessary to limit the radiation dose to family members, nursing staff and members of public and waste treatment workers to less than 1mSv. Patients received Sodium Iodide-131 may come into close contact with other persons. In order to derive appropriate recommendations, dose rates were measured from the anterior mid-trunk of 29 patients in the upright position with 15 minutes post-dose administration at 3 meters and just before they left the nuclear medicine department at 0.5, 1, and 3 meters. We have also measured urinary iodide excretion in 29 patients to estimate Sodium Iodide-131 urinary excretion pattern in iranian patients. Based on results, the maximum cumulative dose to nursing staff was on third day (leaving day) still less than recommended dose bye ICRP. The cumulative dose family members will be more but regarding the time and distance in close contact it will be also less than recommended dose by ICRP.Radiation dose rate was decreased significantly on third day. The urinary excretion patterns in all patients were similar. The urinary excretion rate-time curve in all patients showed multiple peaks due to retention and redistribution of Iodine-131 or enterohepatic cycle of radioiodinated thyroid hormones, which didn't allow calculation of urinary excretion rate constant. The results also showed that 67 hours post administration of Sodium Iodide-131 about 70% of radiopharmaceutical was excreted through urine, 28% physically decayed or eliminated through other biological

    Statins and fibrates (weak PPARα agonists) are prescribed for the treatment of lipid disorders. Both drugs cause myopathy, but with a low incidence, 0.1-0.5%. However, combined statin and fibrate therapy can enhance myopathy risk. We tested the myotoxic potential of PPAR subtype selective agonists alone and in combination with statins in a differentiated rat myotube model. A pharmacologically potent experimental PPARα agonist, Compound A, induced myotoxicity as assessed by TUNEL staining at a minimum concentration of 1 nM, while other weaker PPARα compounds, for example, WY-14643, Gemfibrozil and Bezafibrate increased the percentage of TUNEL-positive nuclei at micromolar concentrations. In contrast, the PPARγ agonist Rosiglitazone caused little or no cell death at up to 10 μM and the PPARδ ligand GW-501516 exhibited comparatively less myotoxicity than that seen with Compound A. An experimental statin (Compound B) and Atorvastatin also increased the percentage of TUNEL-positive nuclei and co-treatment with WY-14643, Gemfibrozil or Bezafibrate had less than a full additive effect on statin-induced cell killing. The mechanism of PPARα agonist-induced cell death was different from that of statins. Unlike statins, Compound A and WY-14643 did not activate caspase 3/7. In addition, mevalonate and geranylgeraniol reversed the toxicity caused by statins, but did not prevent the cell killing induced by WY-14643. Furthermore, unlike statins, Compound A did not inhibit the isoprenylation of rab4 or rap1a. Interestingly, Compound A and Compound B had differential effects on ATP levels. Taken together, these observations support the hypothesis that in rat myotube cultures, PPARα agonism mediates in part the toxicity response to PPARα compounds. Furthermore, PPARα agonists and statins cause myotoxicity through distinct and independent pathways

    Statins and fibrates (weak PPAR{alpha} agonists) are prescribed for the treatment of lipid disorders. Both drugs cause myopathy, but with a low incidence, 0.1-0.5%. However, combined statin and fibrate therapy can enhance myopathy risk. We tested the myotoxic potential of PPAR subtype selective agonists alone and in combination with statins in a differentiated rat myotube model. A pharmacologically potent experimental PPAR{alpha} agonist, Compound A, induced myotoxicity as assessed by TUNEL staining at a minimum concentration of 1 nM, while other weaker PPAR{alpha} compounds, for example, WY-14643, Gemfibrozil and Bezafibrate increased the percentage of TUNEL-positive nuclei at micromolar concentrations. In contrast, the PPAR{gamma} agonist Rosiglitazone caused little or no cell death at up to 10 {mu}M and the PPAR{delta} ligand GW-501516 exhibited comparatively less myotoxicity than that seen with Compound A. An experimental statin (Compound B) and Atorvastatin also increased the percentage of TUNEL-positive nuclei and co-treatment with WY-14643, Gemfibrozil or Bezafibrate had less than a full additive effect on statin-induced cell killing.

  4. Provision of services for the diagnosis and treatment of heart disease. Fourth report of a Joint Cardiology Committee of the Royal College of Physicians of London and the Royal College of Surgeons of England.

    1992-01-01

    The principal conclusions of the fourth report of the Joint Cardiology Committee are: 1 Cardiovascular disease remains a major cause of death and morbidity in the population and of utilisation of medical services. 2 Reduction in the risk of cardiovascular disease is feasible, and better co-ordination is required of strategies most likely to be effective. 3 Pre-hospital care of cardiac emergencies, in particular the provision of facilities for defibrillation, should continue to be developed. 4 There remains a large shortfall in provision of cardiological services with almost one in five district hospitals in England and Wales having no physician with the appropriate training. Few of the larger districts have two cardiologists to meet the recommendation for populations of over 250,000. One hundred and fifty extra consultant posts (in both district and regional centres) together with adequate supporting staff and facilities are urgently needed to provide modest cover for existing requirements. 5 The provision of coronary bypass grafting has expanded since 1985, but few regions have fulfilled the unambitious objectives stated in the Third Joint Cardiology Report. 6 The development of coronary angioplasty has been slow and haphazard. All regional centres should have at least two cardiologists trained in coronary angioplasty and there should be a designated budget. Surgical cover is still required for most procedures and is best provided on site. 7 Advances in the management of arrhythmias, including the use of specialised pacemakers, implantable defibrillators, and percutaneous or surgical ablation of parts of the cardiac conducting system have resulted in great benefit to patients. Planned development of the emerging sub-specialty of arrhythmology is required. 8 Strategies must be developed to limit the increased exposure of cardiologists to ionising radiation which will result from the expansion and increasing complexity of interventional procedures. 9 Supra

    We sought to empirically compare treatment room length-of-stay and patient throughput for recombinant human thyroid-stimulating hormone (rhTSH)-aided thyroid remnant ablation with thyroid hormone withdrawal (THW)-aided ablation in patients with differentiated thyroid carcinoma (DTC). We retrospectively reviewed charts of all eligible (near) totally thyroidectomized patients with DTC undergoing ablation and 1-year ablation success evaluation at our tertiary referral centre from January 2003 to February 2009 (N=274). M1 disease caused exclusion unless discovered by a postablation scan or present when rhTSH was the only tolerable stimulation method. We extracted data on the length-of-stay, defined as the time between treatment room admission and discharge, and patient throughput, defined as patients ablated per treatment room per week. The treatment room discharge criterion was a whole-body dose rate of less than 60 μSv/h at 50 cm. The treatment groups (rhTSH, n=187; THW, n=87) had mostly statistically similar characteristics, but differed in primary tumour status distribution. In addition, at ablation, the rhTSH patients had a greater prevalence of prior diagnostic scintigraphy, higher mean serum TSH, and shorter interval since surgery, and received a 5.6% larger mean ablation activity. On average, rhTSH patients had a significantly lower peak whole-body dose rate (57.1 vs. 83.4 μSv/h at 50 cm; P<0.0001) and a significantly shorter treatment room stay than did the THW patients (1.41 vs. 2.02 days; P<0.001). rhTSH use allowed significantly more patients to be ablated per room per week (2.7 vs. 1.2; P<0.001). Relative to THW, rhTSH use to aid ablation reduced mean treatment room length-of-stay by almost one-third and more than doubled the average weekly patient throughput, both of which were significant differences.

    Cellular dormancy is defined as a state in which cells enter quiescence driven by intrinsic or extrinsic factors, and striking parallels exist between the concept of cellular dormancy in malignancies and the cancer stem cell theory. We showed now that the proven dormancy markers insulin-like growth factor-binding protein 5, ephrin receptor A5 and histone cluster 1 H2B family member K were expressed in human glioblastomas in situ , were located in single tumor cells, and could be co-stained with each other and with the stem cell markers krüppel-like factor 4, octamer binding transcription factor 4 and sex determining region Y-box 2. Human non-stem glioblastoma cell lines and primary cultures were characterized by expression of individual, cell-type specific dormancy- and stemness-associated markers, which were (up)regulated and could be co-stained in a cell-type specific manner upon Temozolomide-induced dormancy in vitro . The induction patterns of dormancy- and stemness-associated markers were reflected by cell-type specific responses to Temozolomide-induced and combined Temozolomide/AT101-mediated cytotoxicity in different glioblastoma cell lines and primary cultures in vitro , and accompanied by higher self-renewal capacity and lower TMZ-sensitivity of Temozolomide-pretreated cells. We postulate that a better understanding of the dormant state of tumor cells is essential to further improve efficiency of treatment.

    Full Text Available Avascular necrosis of the femoral head (ANFH is an a frequently occurring orthopaedic disease with high morbidity. Traditional Chinese Medicine (TCM Yuanshi Shengmai Chenggu Tablet is a valid prescription for treating steroid-induced femoral head necrosis. However, there are rare investigations about the serum protein marker expression after the acting of drugs on hormone and TCM. In the present study, we aimed to systematically discover and validate the serum biomarkers expression difference in patients with steroid-induced avascular necrosis of femoral head (SANFH after taking Yuanshi Shengmai Chenggu Tablets (SANFH-TCM, so as to reveal the action mechanism of TCM from the molecular level by using isobaric tags for relative and absolute quantification (iTRAQ with multiple reaction monitoring quantification. Significant differences in fibrinogen alpha, fibrinogen beta, fibrinogen gamma, fibronectin, C-reactive protein, apolipoprotein A, apolipoprotein D, and apolipoprotein E were found among SANFH, SANFH-TCM, and healthy controls. Therefore, our study proposes potential biomarkers for SANFH diagnosis and for the prognosis of femoral head necrosis after Traditional Chinese Medicine treatment.

    Objective: Much controversy relates to the risk of non-synchronous second primary malignancies (NSSPM) after radioactive iodine treatment (RAI-131) in differentiated thyroid cancer (DTC) patients. This study evaluated the relationship between RAI-131 and NSSPM in DTC survivors with long-term follow-up. Materials and methods: Retrospective analysis of 413 DTC cases was performed; 252 received RAI-131 and 161 were treated with thyroidectomy alone. Exclusion criteria were: prior or synchronous non-thyroidal malignancies (within the first year), familial syndromes associated to multiple neoplasms, ionizing radiation exposure or second tumors with unknown histopathology. Results: During a mean follow-up of 11.0 ± 7.5 years, 17 (4.1%) patients developed solid NSSPM. Patients with NSSPM were older than those without (p = 0.02). RAI-131 and I-131 cumulative activity were similar in patients with and without NSSPM (p = 0.18 and p = 0.78, respectively). Incidence of NSSPM was 5.2% in patients with RAI-131 treatment and 2.5% in those without RAI-131 (p = 0.18). Using multivariate analysis, RAI-131 was not significantly associated with NSSPM occurrence (p = 0.35); age was the only independent predictor (p = 0.04). Under log rank statistical analysis, after 10 years of follow-up, it was observed a tendency of lower NSSPM-free survival among patients that received RAI-131 treatment (0.96 vs. 0.87; p = 0.06), what was not affected by age at DTC diagnosis. Conclusion: In our cohort of DTC survivors, with a long-term follow-up period, RAI-131 treatment and I-131 cumulative dose were not significantly associated with NSSPM occurrence. A tendency of premature NSSPM occurrence among patients treated with RAI-131 was observed, suggesting an anticipating oncogenic effect by interaction with other risk factors. (author)

    A systematic differentiation of culture- in contrast to migration-related influence factors in diagnostic and therapeutic processes is introduced. "Culture-related" refers to characteristics caused by values, behavior norms and religious attitudes of the ethnic community a person belongs to. "Migration-specific" refers to consequences of moving one's residence from one country to another (e. g., absence of family, trouble with authorities concerning the legal status or ambivalence with respect to returning to the home country). Based on a theoretic background of these determinants, categories for a content analysis were defined and applied to the treatment records of n = 55 first generation immigrants treated in a psychiatric day clinic of an university hospital. The results suggest that migration biography should not only be considered as affecting vulnerability in the genesis of a mental illness, but rather be classified as a factor of at least as much relevance for therapeutic situations as the usually named cultural diversity: summarizing the results of the qualitative content analysis of the entire treatment courses more cases were influenced by migration specific aspects rather than culture specific aspects.

    To evaluate the efficacy and safety of "Three-Typed Syndrome Differentiation" (TTSD) in treating type 2 diabetes mellitus patients. A systematic review and meta-analysis was done based on the clinical diabetes treatment literature of the "TTSD". Overseas databases like the PubMed/MEDLINE, EMBASE, Cochrane Library and Cochrane Central Register of Controlled Clinical Trials, and China databases like China Biology Medicine Disc (CBM), Chinese national Knowledge Infrastructure (CNKI), Wanfang database, and VIP database, without limitation on language, were included with the time limitation from Jan 1982 to Dec 2012 by retrieval of relative original clinical research articles. Nineteen articles where contains 1,840 diabetes patients were obtained, in which no adverse reactions were reported. Of these, 14 literatures involved the effect of fasting blood glucose (FBG), 10 involved that of postprandial 2-h blood glucose (P2hBG), and 19 involved the overall efficacy based on the national Chinese medicine (CM) diagnosis and treatment standard of diabetes. All the meta-analysis results prefer to the "TTSD" groups (CM+Western medicine Based on TTSD). The results show that, beside the efficacy of Western medicine, the concentrations of FBG and P2hBG in "TTSD" groups continue to drop with statistical significance. For "TTSD" groups, the FBG subsequently dropped 1.03 mmol/L, 95%CI [1.24,0.82] P dropped 1.09 mmol/L, 95% CI [1.61, 0.57] (P treatment of type 2 diabetes based on TTSD might be safe and effective, and could better improve both blood glucose and the overall status of patients, including symptoms.

    A study directed to the cytogenetic and dosimetric aspects of radionuclides of medical interest is very valuable, both for an accurate evaluation of the dose received by the patients, and consequently of the genetic damage, and for the optimization of therapeutic strategies. Cytogenetic and dosimetric effects of {sup 131}I in lymphocytes of thyroidectomized differentiated thyroid cancer (DTC) patients were evaluated through chromosome aberration (CA) technique: Euthyroid patients submitted to recombinant human thyroid-stimulating hormone (rhTSH) therapy (group A) were compared with hypothyroid patients left without levothyroxine treatment (group B). CA analysis was carried out prior to and 24 h, 1 week, 1 month and 1 year after radioiodine administration (4995-7030 MBq) in both groups. An activity-response curve of {sup 131}I (0.074-0.740 MBq/mL) was elaborated, comparing dicentric chromosomes in vivo and in vitro in order to estimate the absorbed dose through Monte Carlo simulations. In general, radioiodine therapy induced a higher total CA rate in hypothyroid patients as compared to euthyroid patients. The frequencies of dicentrics obtained in DTC patients 24 h after treatment were equivalent to those induced in vitro (0.2903 ± 0.1005 MBq/mL in group A and 0.2391 ± 0.1019 MBq/mL in group B), corresponding to absorbed doses of 0.65 ± 0.23 Gy and 0.53 ± 0.23 Gy, respectively. The effect on lymphocytes of internal radiation induced by {sup 131}I therapy is minimal when based on the frequencies of CA 1 year after the treatment, maintaining a higher quality of life for DTC patients receiving rhTSH-aided therapy.

    Idiopathic normal pressure hydrocephalus (INPH) diagnosis is challenging as it can be mimicked by other neurological conditions, such as neurodegenerative dementia and motor syndromes. Additionally, outcomes after lumbar puncture (LP) tap test and shunt treatment may vary due to the lack of a common protocol in INPH assessment. The present study aimed to assess whether a post-LP test amelioration of frontal cognitive dysfunctions, characterizing this syndrome, can differentiate INPH from similar neurological conditions and whether this improvement can predict INPH post-shunt outcomes. Seventy-one consecutive patients referred for INPH suspicion and LP testing, were enrolled. According to the consensus guidelines criteria, 29 patients were diagnosed as INPH and 42 were assigned an alternative diagnosis (INPH-like group) after reviewing clinical, neuropsychological and imaging data, and before LP results. A comprehensive neuropsychological assessment for frontal executive, upper extremity fine motor functions, aphasias, apraxias, agnosias and gait evaluation were administered at baseline. Executive, fine motor functions and gait were re-examined post-LP test in all patients and post-shunt placement in INPH patients. Of the INPH patients, 86.2% showed cognitive amelioration in the post-LP test; in addition, all but one (97%) presented with neurocognitive and gait improvement post-shunt. Verbal phonological fluency and finger tapping task post-LP improvement predicted positive clinical outcome post-shunt. None of the INPH-like group presented with neurocognitive improvement post-LP. Post-LP amelioration of verbal fluency and finger tapping deficits can differentiate INPH from similar disorders and predict positive post-shunt clinical outcome in INPH. This becomes of great importance when gait assessment is difficult to perform in clinical practice.

    Brazil's National Tuberculosis Control Program seeks to improve tuberculosis (TB) treatment in vulnerable populations. Slum residents are more vulnerable to TB due to a variety of factors, including their overcrowded living conditions, substandard infrastructure, and limited access to healthcare compared to their non-slum dwelling counterparts. Directly observed treatment (DOT) has been suggested to improve TB treatment outcomes among vulnerable populations, but the program's differential effectiveness among urban slum and non-slum residents is not known. We retrospectively compared the impact of DOT on TB treatment outcome in residents of slum and non-slum census tracts in Rio de Janeiro reported to the Brazilian Notifiable Disease Database in 2010. Patient residential addresses were geocoded to census tracts from the 2010 Brazilian Census, which were identified as slum (aglomerados subnormais -AGSN) and non-slum (non-AGSN) by the Census Bureau. Homeless and incarcerated cases as well as those geocoded outside the city's limits were excluded from analysis. In 2010, 6,601 TB cases were geocoded within Rio de Janeiro; 1,874 (27.4 %) were residents of AGSN, and 4,794 (72.6 %) did not reside in an AGSN area. DOT coverage among AGSN cases was 35.2 % (n = 638), while the coverage in non-AGSN cases was 26.2 % (n = 1,234). Clinical characteristics, treatment, follow-up, cure, death and abandonment were similar in both AGSN and non-AGSN TB patients. After adjusting for covariates, AGSN TB cases on DOT had 1.67 (95 % CI: 1.17, 2.4) times the risk of cure, 0.61 (95 % CI: 0.41, 0.90) times the risk of abandonment, and 0.1 (95 % CI: 0.01, 0.77) times the risk of death from TB compared to non-AGSN TB cases not on DOT. While DOT coverage was low among TB cases in both AGSN and non-AGSN communities, it had a greater impact on TB cure rate in AGSN than in non-AGSN populations in the city of Rio de Janeiro.

A new approach neutralizes distributional concerns by adjusting the income tax schedule. We demonstrate that both approaches are derived from the same...... basic formula. We also take the new approach further by deriving an intuitive formula for the optimal level of public goods, without imposing strong assumptions on preferences.

The standard approach highlights the importance of distortionary taxation and distributional concerns. The new approach neutralizes distributional concerns by adjusting the non-linear income...... tax, and finds that this reinvigorates the simple Samuelson rule when preferences are separable in goods and leisure. We provide a synthesis by demonstrating that both approaches derive from the same basic formula. We further develop the new approach by deriving a general, intuitive formula...

    Growth inhibition of murine and human myeloid leukemia cells by differentiation inducers during long-term culture was examined to improve the strategy for therapy of myeloid leukemia by differentiation inducers. When the effect of 1 alpha,25-dihydroxyvitamin D3, a typical differentiation inducer, on proliferation of mouse myeloid leukemia M1 cells was examined at a constant product of time and concentration (480 nM in 20 days), the continuous treatment with 24 nM 1 alpha,25-dihydroxyvitamin D3 was the most effective for inhibition of cell proliferation. After 20 days, the cumulative cell number was reduced about 3 X 10(5) times by continuous treatment with 24 nM 1 alpha,25-dihydroxyvitamin D3. Similar results were obtained when M1 cells were treated continuously with dexamethasone. M1 cells resistant to 1 alpha,25-dihydroxyvitamin D3 appeared about 25 days after the start of continuous treatment with 24 nM 1 alpha,25-dihydroxyvitamin D3. On the other hand, when M1 cells were treated continuously with 1 alpha,25-dihydroxyvitamin D3 and noncytotoxic doses of antileukemic drugs such as 1-beta-D-arabinofuranosylcytosine and daunomycin, resistant cells did not appear for at least 35 days. A similar effect of 1 alpha,25-dihydroxyvitamin D3 and antileukemic drugs on cell proliferation was observed with the human monoblast-like cell line U937. The survival of syngeneic SL mice inoculated with M1 cells was prolonged more by treatment with both 1 alpha-hydroxyvitamin D3 and daunomycin than by treatment with either drug alone. These results suggest that continuous treatment with both differentiation inducers and certain antileukemic drugs may be more effective therapeutically than treatment with a differentiation inducer alone.

    Tuberculosis (Tb) is an infectious disease in which the immune system plays an important role. MicroRNAs are involved in the development and maintenance of CD4 + T lymphocyte subpopulations. miR-326 regulates the differentiation to Th17 cells and miR-29 correlates with the Th1 response. The aim of this study was to determine the role of microRNAs, Transcription Factors, and cytokines in Th differentiation before and after the directly observed treatment short-course (DOTS). Peripheral blood mononuclear cells and serum from Tb patients were collected at times 0 (before therapy), 2 (after the intensive phase), and 6 months (after the holding phase). The cells were cultivated in presence or absence of ESAT-6 (10 μg/ml) and CFP-10 (10 μg/ml). Transcription Factor and microRNA expressions were analyzed by qPCR and cytokine production in both serum and culture supernatant using ELISA. A decrease in Th1 response with a diminishing in the relative expression of TBET and miR-29a at 2 and 6 months after the anti-Tb therapy (p < 0.01) were found. The miR-326 levels decreased after the intensive phase of the DOTS scheme. However, subdivision of the Tb patients according to gender, showed increased levels of miR-29a and miR-155 in females after the intensive phase of the therapeutic treatment when compared to time 0 and similar increased levels of miR-326 at time 6 versus time 0. In contrast, we observed a decrease in miR-326 levels in males at 6 months when compared to before therapy (time 0). In addition, high production of IL-17 in the culture supernatant was found at 2 and 6 months (p < 0.05) while in serum IL-17 was decreased. A positive correlation between IL-17 and RORC2 at time 6 was detected (p = 0.0202, r = 0.7880). In conclusion, these data suggest a reduction in Th1 and an induction of Th17 response after the anti-Tb therapy. Copyright © 2017 Elsevier Ltd. All rights reserved.

  1. Sustainability of ARV provision in developing countries: challenging a framework based on program history

    Directory of Open Access Journals (Sweden)

    Thiago Botelho Azeredo

    Full Text Available Abstract The provision of ARVs is central to HIV/AIDS programs, because of its impact on the course of the disease and on quality of life. Although first-line treatments costs have declined, treatment-associated expenses are steeper each year. Sustainability is therefore an important variable for the success of treatment programs. A conceptual framework on sustainability of ARV provision was developed, followed by data collection instruments. The pilot study was undertaken in Brazil. Bolivia, Peru and Mozambique, were visited. Key informants were identified and interviewed. Investigation of sustainability related to ARV provision involved implementation and routinization events of provision schemes. Evidence of greater sustainability potential was observed in Peru, where provision is implemented and routinized by the National HIV/AIDS program and expenditures met by the government. In Mozambique, provision is dependent on donations and external aid, but the country displays a great effort to incorporate ARV provision and care in routine healthcare activities. Bolivia, in addition to external dependence on financing and management of drug supply, presents problems regarding implementation and routinization. The conceptual framework was useful in recognizing events that influence sustainable ARV provision in these countries.

    Acne is a common skin disease characterized by elevated sebum production and inflammation of the sebaceous glands. We have previously shown that a non-psychotropic phytocannabinoid ((-)-cannabidiol [CBD]) exerted complex anti-acne effects by normalizing 'pro-acne agents'-induced excessive sebaceous lipid production, reducing proliferation and alleviating inflammation in human SZ95 sebocytes. Therefore, in this study we aimed to explore the putative anti-acne effects of further non-psychotropic phytocannabinoids ((-)-cannabichromene [CBC], (-)-cannabidivarin [CBDV], (-)-cannabigerol [CBG], (-)-cannabigerovarin [CBGV] and (-)-Δ(9) -tetrahydrocannabivarin [THCV]). Viability and proliferation of human SZ95 sebocytes were investigated by MTT and CyQUANT assays; cell death and lipid synthesis were monitored by DilC1 (5)-SYTOX Green labelling and Nile Red staining, respectively. Inflammatory responses were investigated by monitoring expressions of selected cytokines upon lipopolysaccharide treatment (RT-qPCR, ELISA). Up to 10 μm, the phytocannabinoids only negligibly altered the viability of the sebocytes, whereas high doses (≥50 μm) induced apoptosis. Interestingly, basal sebaceous lipid synthesis was differentially modulated by the substances: CBC and THCV suppressed it, and CBDV had only minor effects, whereas CBG and CBGV increased it. Importantly, CBC, CBDV and THCV significantly reduced arachidonic acid (AA)-induced 'acne-like' lipogenesis. Moreover, THCV suppressed proliferation, and all phytocannabinoids exerted remarkable anti-inflammatory actions. Our data suggest that CBG and CBGV may have potential in the treatment of dry-skin syndrome, whereas CBC, CBDV and especially THCV show promise to become highly efficient, novel anti-acne agents. Moreover, based on their remarkable anti-inflammatory actions, phytocannabinoids could be efficient, yet safe novel tools in the management of cutaneous inflammations. © 2016 John Wiley & Sons A/S.

  3. Differential effects of Rho-kinase inhibitor and angiotensin II type-1 receptor antagonist on the vascular function in hypertensive rats induced by chronic l-NAME treatment

    Full Text Available Little attention has been paid to the effect of Rho-kinase inhibitor on the vascular dysfunction of nitric oxide-deficient hypertension. We aimed to investigate whether the Rho-kinase inhibitor fasudil showed beneficial effect on the vascular dysfunction of the NG-nitro-l-arginine methyl ester (l-NAME treated rat, as well as to compare the differential effects of fasudil and angiotensin II receptor antagonist valsartan on vascular function. In the present study, both valsartan and fasudil exerted antihypertensive action on the l-NAME-treated rats, while only valsartan attenuated the cardiac hypertrophy. Treatment with valsartan showed improvement on vascular reactivity to norepinephrine, KCl and CaCl2, whereas fasudil therapy showed little effect on vasoconstriction. Endothelium-dependent vasodilation to acetylcholine was reduced in the NO-deficient group but was normalized by the fasudil therapy. The increased expression of RhoA and Rho-kinase (ROCK in the vasculature was corrected well to normal level by either valsartan or fasudil administration, which seemed to be at least partially responsible for the beneficial effect of the drug infusion. These findings suggest that the angiotensin II receptor antagonist interferes more with the contractile response than Rho-kinase inhibitor, whereas inhibition of Rho-kinase activity exhibits a better improvement on vasorelaxation than blockade of angiotensin II receptor.

  8. Differentially expressed miRNAs after GnRH treatment and their potential roles in FSH regulation in porcine anterior pituitary cell.

    Directory of Open Access Journals (Sweden)

    Rui-Song Ye

    Full Text Available Hypothalamic gonadotropin-releasing hormone (GnRH is a major regulator of follicle-stimulating hormone (FSH secretion in gonadotrope cell in the anterior pituitary gland. microRNAs (miRNAs are small RNA molecules that control gene expression by imperfect binding to the 3'-untranslated region (3'-UTR of mRNA at the post-transcriptional level. It has been proven that miRNAs play an important role in hormone response and/or regulation. However, little is known about miRNAs in the regulation of FSH secretion. In this study, primary anterior pituitary cells were treated with 100 nM GnRH. The supernatant of pituitary cell was collected for FSH determination by enzyme-linked immunosorbent assay (ELISA at 3 hours and 6 hours post GnRH treatment respectively. Results revealed that GnRH significantly promoted FSH secretion at 3 h and 6 h post-treatment by 1.40-fold and 1.80-fold, respectively. FSHβ mRNA at 6 h post GnRH treatment significantly increased by 1.60-fold. At 6 hours, cells were collected for miRNA expression profile analysis using MiRCURY LNA Array and quantitative PCR (qPCR. Consequently, 21 up-regulated and 10 down-regulated miRNAs were identified, and qPCR verification of 10 randomly selected miRNAs showed a strong correlation with microarray results. Chromosome location analysis indicated that 8 miRNAs were mapped to chromosome 12 and 4 miRNAs to chromosome X. Target and pathway analysis showed that some miRNAs may be associated with GnRH regulation pathways. In addition, In-depth analysis indicated that 10 up-regulated and 3 down-regulated miRNAs probably target FSHβ mRNA 3'-UTR directly, including miR-361-3p, a highly conserved X-linked miRNA. Most importantly, functional experimental results showed that miR-361-3p was involved in FSH secretion regulation, and up-regulated miR-361-3p expression inhibited FSH secretion, while down-regulated miR-361-3p expression promoted FSH secretion in pig pituitary cell model. These differentially

    The effects of internal irradiation caused by radiopharmaceuticals being utilized in nuclear medicine are very little studied at the cellular level. In this study, cytogenetic effects of 131 I thyroid remnant ablation were analyzed in lymphocytes of thyroidectomized differentiated thyroid cancer patients (DTC) through the chromosome aberration technique. The chromosome damages radioinduced in euthyroid patients submitted to rhTSH (Thyrogen) therapy (Group A) were compared to those induced in patients maintained in hypothyroid condition through levothyroxine withdrawal (L-T 4 ) (group B), before, 24h, one week and one month after radioiodine administration (4995 - 7030 MBq). In parallel, in vitro assays were carried out with lymphocytes of healthy donors for the construction of dose-response curves at different radioactive concentrations of 131 I (0.074 to 0.740 MBq/mL) for 24h, thus comparing chromosome damages in vivo and in vitro in order to estimate the absorbed dose through Monte Carlo program. Radioiodine therapy induced a higher total CA rate in hypothyroid compared with euthyroid patients, except 24h after administration of 131 I probably due to higher uptake induced by TSH, although without statistical significance (p > 0.05). The frequency of dicentrics obtained in lymphocytes of all patients 24h after treatment, was equivalent to that induced in vitro in the radioactive concentrations range of 0.07 to 0.50 MBq/mL, corresponding to an absorbed dose of up 1.0 Gy. The data obtained suggest that the use of rhTSH-aided thyroid remnant ablation is efficacy and secure for the patients with DTC. Cytogenetic analysis after one year are planned in order to evaluate late effects. (author)

    After severe reactor emergencies with release of radioactive iodine, elevated thyroid cancer risk in children and adolescents is considered the main health consequence for the population exposed. We studied thyroid cancer outcome after 11.3 years' median follow-up in a selected, very high-risk cohort, 234 Chernobyl-exposed Belarusian children and adolescents undergoing postsurgical radioiodine therapy (RIT) in Germany. Cumulatively 100 children with or (without; n = 134) distant metastasis received a median 4 (2) RITs and 16.9 (6.6) GBq, corresponding to 368 (141) MBq/kg iodine-131. Outcomes were response to therapy and disease status, mortality, and treatment toxicity. Of 229 patients evaluable for outcome, 147 (64.2%) attained complete remission [negative iodine-131 whole-body scan and TSH-stimulated serum thyroglobulin (Tg) 10 μg/L, decrease from baseline in radioiodine uptake intensity in ≥ 1 focus, in tumor volume or in Tg). Except for 2 recurrences (0.9%) after partial remission, no recurrences, progression, or disease-specific mortality were noted. One patient died of lung fibrosis 17.5 years after therapy, 2 of apparently thyroid cancer-unrelated causes. The only RIT side effect observed was pulmonary fibrosis in 5 of 69 patients (7.2%) with disseminated lung metastases undergoing intensive pulmonary surveillance. Experience of a large, very high-risk pediatric cohort with radiation-induced differentiated thyroid carcinoma suggests that even when such disease is advanced and initially suboptimally treated, response to subsequent RIT and final outcomes are mostly favorable.

    Background: We tried to evaluate the female fertility and genetic risk to the offspring from the exposure to high-dose 131 I by assessing the pregnancy outcomes and health status of the children of female patients with differentiated thyroid cancer who had received therapeutic doses of 131 I. Materials and Methods: From 1967 to 2002, a total of 1,282 women had been treated with 131 I. Of these patients, 692 (54%) were in the reproductive age group (18-45 years). Forty women had a total of 50 pregnancies after high-dose 131 I. Age at presentation ranged from 16 to 36 years (mean, 23 ± 4 years). Histopathology was papillary thyroid cancer in 32 cases and follicular thyroid cancer in 8 cases. Results: Single high-dose therapy was given in 30 cases, 2 doses were given in 7 cases, 3 doses were given in 2 cases, and four doses were given in 1 case in which lung metastases had occurred. In 37 patients (92%), disease was successfully ablated before pregnancy. Ovarian absorbed-radiation dose calculated by the MIRD method ranged from 3.5 to 60 cGy (mean, 12 ± 11 cGy). The interval between 131 I therapy and pregnancy varied from 7 to 120 months (37.4 ± 28.2 months). Three spontaneous abortions occurred in 2 women. Forty-seven babies (20 females and 27 males) were born. Forty-four babies were healthy with normal birth weight and normal developmental milestones. Twenty women delivered their first baby after 131 I therapy. The youngest child in our series is 11 months of age, and the oldest is 8.5 years of age. Conclusions: Female fertility is not affected by high-dose radioiodine treatment, and the therapy does not appear to be associated with any genetic risks to the offspring

    Inappropriate fetal exposure to maternal glucocorticoid (GC) has been proposed as a mechanism for fetal programming where the effects of GC may be mediated by the placenta. However, the consequences of maternal GC on placental morphology and enzyme expression are unclear. We used betamethasone (BET) to determine effects on placentome subtype distribution and expression of prostaglandin H synthase type 2 (PGHS-2) enzyme. Pregnant sheep carrying male fetuses were randomized to receive injections of saline (n = 30) or one (104 days of gestation, (dG); n = 6), two (104, 111 dG; n = 6) or three (104, 111, 118 dG; n = 11) doses of BET (0.5 mg/kg). Placental tissue was collected prior to (75, 84, 101 dG), during (109, 116 dG) and after BET (122, 132, 146 dG). Total number of placentomes was not different between gestational ages. A- and B-subtypes were most affected by prenatal BET exposure; numbers of A-subtypes were increased and numbers of B-subtypes were decreased compared to controls at 116 dG. At term numbers of A-subtypes were lower after BET, but the weight range distribution was similar to controls. In controls, placental PGHS-2 protein levels increased with gestational age and PGHS-2 localized primarily to uninuclear trophoblast cells. After BET, PGHS-2 protein in C-subtypes at term was significantly increased compared to A-subtypes. Maternal BET treatment in late gestation affects the proportions of placentome subtypes and their differential expression of PGHS-2. Our data do not support previous hypotheses that A-subtypes develop into B-, C- and D-subtypes over the course of gestation. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Lipoprotein-apheresis (LA) is a therapeutic approach used against severe forms of dyslipidemia in patients who are non-responders or intolerant to pharmacological treatments. However, little is known about the potential pleiotropic effects of LA, particularly regarding the immune system and its regulation. Thus, in an attempt to analyse the potential effects of dyslipidemia and LA on the regulation of CD4 + T cells activation and lineage differentiation, we compared the CD4 + T cells cytokines secretion profiles of dyslipidemic patients before and after LA with the profiles observed in healthy donors. CD4 + T cells were isolated from 5 LA patients and 5 healthy donors and activated with anti-CD3 or anti-CD3 + anti-CD46 antibodies. The supernatants were collected after 36 h incubation and levels of secreted cytokines analysed by flow cytometry. Our results revealed a deep remodelling of CD4 + T cells cytokines secretion patterns in dyslipidemic patients compared to healthy donors, as reflected by a 15 times higher IFN-γ secretion rate after CD3 + CD46 co-activation in dyslipidemic patients after LA compared to healthy subjects and 8 times higher after CD3 activation alone (p = 0.0187 and p = 0.0118 respectively). Moreover, we demonstrated that LA itself also modifies the phenotype and activation pattern of CD4 + T-cells in dyslipidemic patients. These observations could be of fundamental importance in the improvement of LA columns/systems engineering and in developing new therapeutic approaches regarding dyslipidemia and associated pathologies such as atherosclerosis and type 2 diabetes.

  16. Costs of egg-laying and offspring provisioning: multifaceted parental investment in a digger wasp.

    2007-02-07

    Nest-building Hymenoptera have been a major testing ground for theories of parental investment and sex allocation. Investment has usually been estimated by the likely costs of offspring provisioning, ignoring other aspects of parental care. Using three experimental treatments, we estimated the costs of egg-laying and provisioning separately under field conditions in a digger wasp Ammophila pubescens. In one treatment, we increased the provisioning effort required per offspring by removing alternate prey items as they were brought to the nest. In two other treatments, we reduced parental effort by either preventing females from provisioning alternate nests or preventing them from both ovipositing and provisioning. Our results indicate that both egg-laying and provisioning represent significant costs of reproduction, expressed as differences in productivity but not survival. A trade-off-based model suggests that other components of parental care such as nest initiation may also represent significant costs. Costs of egg production and nest initiation are probably similar for male and female offspring, so that taking them into account leads to a less male-biased expected sex ratio. Mothers compensated only partially for prey removal in terms of the total provisions they gave to individual offspring.

  17. Differentiation of subdural effusions

    1989-01-01

    Although X-ray computerized tomography facilitates the diagnosis of intracranial disorders, differentiation of the lesions like extracerebral effusions is often unsatisfactory. Epidural and acute subdural haematoma shown as hyperdensity in CT requires an emergency neurosurgical operation, so that differentiation of these hyperdense effusions may not be required. But the discrimination of the effusions shown as hypodensity in CT (chronic subdural haematoma, subdural hygroma, subdural empyema as well as arachnoid cysts) is urgent because of the different treatment of these effusions. The clinical differentiation is hampered by unspecific neurologic symptoms and the lack of adequate laboratory tests. Some aspects facilitating the diagnostic decision are presented. Recent magnetic resonance (MR) studies promise further progress in differentiating between subdural effusions. (orig.) [de

    The new bill before the Senate, the American Recovery and Reinvestment Act of 2009, allows for an additional amount for 'Fossil Energy Research and Development' of $4.6 billion, to be available until 30 September 2010 and that $2 billion of that is available for one or more near zero emissions power plant(s). Two further provisions allow for an additional $1 billion for the Department's Clean Coal Power Initiative Round III and a further $1.5 billion for a competitive solicitations for projects that demonstrate carbon capture from industrial sources. Awards for such projects may include plant efficiency improvements for integration with carbon capture technology. The press seems to be divided whether this money will help revive the FutureGen project. The financial commitment should help the G8 achieve its objective of seeing 20 CCS demonstration projects around the world by 2020. An economic stimulus package proposed by the incoming Barack Obama administration include $150 billion to be spent over 10 years to spur next generation biofuels, plug in hybrid vehicles, a new digital electrical grid and new low emission coal plants. The proposal is intended to create jobs and address critical infrastructure in the US.

  10. Implementing the optimal provision of ecosystem services.

    Many ecosystem services are public goods whose provision depends on the spatial pattern of land use. The pattern of land use is often determined by the decisions of multiple private landowners. Increasing the provision of ecosystem services, though beneficial for society as a whole, may be costly to private landowners. A regulator interested in providing incentives to landowners for increased provision of ecosystem services often lacks complete information on landowners' costs. The combination of spatially dependent benefits and asymmetric cost information means that the optimal provision of ecosystem services cannot be achieved using standard regulatory or payment for ecosystem services approaches. Here we show that an auction that sets payments between landowners and the regulator for the increased value of ecosystem services with conservation provides incentives for landowners to truthfully reveal cost information, and allows the regulator to implement the optimal provision of ecosystem services, even in the case with spatially dependent benefits and asymmetric information.

    Background Education of primary care providers about diagnosis and treatment of depression and anxiety is an evidence-based suicide prevention measure.Aim To analyse suicide index, mental health epidemiological data and primary care provision in Slovenian regions and to identify examples of good suicide prevention practices in different Slovenian regions.Methods Analysis of existent epidemiological data on mental health in Slovenia.Results Anxiety and depression are the most common complaints in a representative sample of the Slovene population. The number of suicides in Slovenia had been dropping in the period from 2002 to 2006 and was again slowly rising in 2008. The number of visits to family physicians' practices because of mental health problems is low in comparison to other European countries, which might be attributed also to the high workload of family physicians. Suicide prevention programmes follow the example of the Suicide Prevention Project in the central-east region of Slovenia. This programme is based on education of primary care providers and the general public about recognition and treatment of depression in line with international guidelines.Conclusions The differentiation of causes for suicide reduction needs further research, as well as urgent improvement in the accessibility of primary care teams in Slovenia.

    High-dose radioiodine treatment (HD-RIT) after injection of recombinant human thyroid stimulating hormone (rh-TSH) has become widely used. This study compared the therapeutic efficacy of HD-RIT and clinical parameters between rh-TSH supplement and thyroid hormone withdrawal (THW) after total thyroidectomy in patients with differentiated thyroid cancer. We retrospectively reviewed 266 patients (47 male and 219 female; age, 49.0 ± 10.9 years) with differentiated thyroid cancer detected from September 2011 to September 2012. Patients comprised THW (217, 81.6 %) and rh-TSH (49, 18.4 %). Inclusion criteria were: first HD-RIT; any TN stage; absence of distant metastasis. To evaluate the complete ablation of the remnant thyroid tissue or metastasis, we reviewed stimulated serum thyroglobulin (sTg), I-123 whole-body scan (RxWBS) on T4 off-state, and thyroid ultrasonography (US) or [F-18]-fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) 6–8 months after HD-RIT. We defined a complete ablation state when all three of the follow-up conditions were satisfied; <2.0 ng/ml of the sTg, I-123 RxWBS (−), and thyroid US or F-18 FDG PET/CT (−). If one of the three was positive, ablation was considered incomplete. We also compared various clinical biomarkers (body weight, body mass index, liver and kidney function) between THW and rh-TSH groups. The rates of complete ablation were 73.7 % (160/217) for the THW group and 73.5 % (36/49) for the rh-TSH group. There was no significant difference between the two groups (p = 0.970). The follow-up aspartate transaminase (p = 0.001) and alanine transaminase (p = 0.001) were significantly higher in the THW group. The renal function parameters of blood urea nitrogen (p = 0.001) and creatinine (p = 0.005) tended to increase in the THW group. The change of body weight was + Δ0.96 (±1.9) kg for the THW group and was decreased by -Δ1.39 (±1.5) kg for the rh-TSH group. The change

    Transgender individuals have unique health care needs and experience health disparities. There is an increased need for transgender health care services and primary care for this underserved population. However, provision of appropriate health care services for transgender persons requires cultural competency and skill on the part of the health care provider, and providers need specific skills to address the needs of this population. A review of the literature was performed by accessing CINAHL, PsycINFO, and PubMed databases. Pertinent research was extracted and reviewed for relevance. References in these publications were reviewed to identify additional publications that address primary prevention, secondary prevention, and tertiary care of transgender individuals. Articles that include prevention, screening, and treatment of health problems of transgender persons were identified. Research on the health needs of the transgender population is limited. Whenever available, research findings that address this unique population should be incorporated into clinical practice. When research evidence is not available to address the unique needs of transgender individuals, research and clinical care guidelines from the general population may be applied for health screening and maintenance. This article provides information about primary care services for transgender individuals and seeks to improve awareness of the health disparities this underserved population experiences. Simple solutions to modify clinical settings to enhance care are provided. © 2016 by the American College of Nurse-Midwives.

    Purpose: To investigate the possible differences between SPECT/CT based whole-remnant and maximum-voxel dosimetry in patients receiving radio-iodine ablation treatment of differentiated thyroid cancer (DTC). Methods: Eighteen DTC patients were administered 1.11 GBq of {sup 131}I-NaI after near-total thyroidectomy and rhTSH stimulation. Two patients had two remnants, so in total dosimetry was performed for 20 sites. Three SPECT/CT scans were performed for each patient at 1, 2, and 3–7 days after administration. The activity, the remnant mass, and the maximum-voxel activity were determined from these images and from a recovery-coefficient curve derived from experimental phantom measurements. The cumulated activity was estimated using trapezoidal-exponential integration. Finally, the absorbed dose was calculated using S-values for unit-density spheres in whole-remnant dosimetry and S-values for voxels in maximum-voxel dosimetry. Results: The mean absorbed dose obtained from whole-remnant dosimetry was 40 Gy (range 2–176 Gy) and from maximum-voxel dosimetry 34 Gy (range 2–145 Gy). For any given patient, the activity concentrations for each of the three time-points were approximately the same for the two methods. The effective half-lives varied (R = 0.865), mainly due to discrepancies in estimation of the longer effective half-lives. On average, absorbed doses obtained from whole-remnant dosimetry were 1.2 ± 0.2 (1 SD) higher than for maximum-voxel dosimetry, mainly due to differences in the S-values. The method-related differences were however small in comparison to the wide range of absorbed doses obtained in patients. Conclusions: Simple and consistent procedures for SPECT/CT based whole-volume and maximum-voxel dosimetry have been described, both based on experimentally determined recovery coefficients. Generally the results from the two approaches are consistent, although there is a small, systematic difference in the absorbed dose due to differences in the

    Patterns of service delivery and the organisation of Dental General Anaesthesia (DGA) have been found to differ across hospitals. This paper reports on qualitative research aimed to understand the impact of such variation by exploring views and experiences of families receiving care in different hospital sites, as well as dentists involved in referral and delivery of care. Qualitative semi-structured interviews were conducted with 26 people comprising parents (n = 15), dentists working in primary care (n = 6) and operating dentists (n = 5) in relation to DGA. Participants were recruited from areas across the North West of England to ensure a variety referral and treatment experiences were captured. Field notes were made during visits to all settings included in the study and explored alongside interview transcripts to elicit key themes. A variety of positive and negative impacts on children and parents throughout the referral process and operation day were apparent. Key themes established were clustered around three key topics: 1. Organisational and professional concerns regarding referrals, delivery of treatment and prevention. 2. The role of hospital environment and routine on the emotional experiences of children. 3. The influence of the wider social context on dental health. These findings suggest the need and perceived value of: tailored services for children (such as play specialists) and improved information, such as clear guidance regarding wait times and what is to be expected on the day of the procedure. These features were viewed to be helpful in alleviating the stress and anxiety often associated with DGA. While some elements will always be restricted in part to the hospital setting in which they occur, there are several aspects where best practice could be shared amongst hospitals and, where issues such as wait times have been acknowledged, alternative pathways can be explored in order to address areas which can impact negatively on children.

    Recombinant human TSH (rhTSH) can be used for post-surgical radioiodine (I-131) thyroid remnants ablation in differentiated thyroid cancer (DTC) patients after surgery. Debate exists in literature about the optimal amount of I-131 that should be given for obtaining an effective ablation and about the role of iodine pool during treatment. Therefore, the aim of the present study was to assess whether I-131 ablation during rhTSH stimulus can be improved by reducing the circulating iodine pool and by increasing thyroid cell uptake and retention of I-131 obtained by administering furosemide and lithium. A total of 201 consecutive DTC patients were entered in the study: they were treated by total thyroidectomy and I-131 therapy during rhTSH stimulus to ablate thyroid remnants. Patients were divided into two groups according to the TNM stage: group 1 included patients in stage I-II who were treated with a low 30-mCi I-131 dose, while group 2 included patients in stage III-IV who were treated by a high 100-mCi I-131 dose. Moreover, both groups were further subdivided into three subgroups. Subgroup (a) included 45 patients from group 1 and 22 from group 2: they were treated with I-131 under rhTSH stimulus, following a short 4-day withdrawal of L-thyroxine (LT4). Subgroup (b) included 45 patients from group 1 and 22 from group 2: they were treated with I-131 under rhTSH stimulus, following a short 4-day withdrawal of L-T4, and after furosemide administration (25 mg/day orally) during the 3 days before I-131. Subgroup (c) included 45 patients from group 1 and 22 from group 2: they were treated with I-131 under rhTSH stimulus, following a short 4-day L-T4 withdrawal, and after administration of furosemide (25 mg/day orally) during the 3 days prior I-131 and lithium (450 mg/day orally) during the 3 days following I-131. Another group (group 3) of 20 patients characterized by a very low-risk cancer (unifocal tumor <1.0 cm in diameter, without extra-capsular extension, N0) was

    The National Service Framework advocates correction of anaemia in patients with chronic kidney disease (CKD). Oral iron is insufficient, while intravenous (IV) supplementation replenishes and maintains iron stores. In Yorkshire numerous peripheral clinics exist to reduce travel for patients, but patients must travel to the main unit for IV iron therapy. Therefore an outpatient service in tandem with a routine clinic for administration of IV CosmoFer was created. To evaluate the feasibility and benefits of IV iron therapy in the outpatient clinic during active patient review for CKD patients. A cross-sectional study of patients attending for total dose IV iron (n = 57) at a peripheral clinic. Iron was administered and monitored according to protocol by one of the clinic nurses with medical staff available in the adjoining room. Haemoglobin, ferritin and renal function were recorded pre-infusion and after 4-6 months. Results are given as medians/means +/- standard error. A total of 76 IV infusions were carried out with no reported side effects or haemodynamic instability. Haemoglobin (median 10.9 vs. 11.3 g dL(-1), P = NS), creatinine and estimated glomerular filtration rate (eGFR) over the 6-month period remained stable. Serum ferritin rose significantly [80.9 +/- 6.2 vs. 186.4 +/- 18.2 g L(-1) (P Hospital time saved 380 day case bed hours, doctor hours saved 76 hours, and patient hours saved 3 hours/patient. Cost savings for TDI CosmoFer in peripheral clinic versus in centre therapy and versus sucrose, respectively, for 76 treatments was pound 5749.40 and pound 46,320.80 respectively. We have demonstrated, in a resource-limited service, the feasibility and cost-effectiveness of a management care pathway for patients with CKD, in a peripheral clinic, to receive total dose IV CosmoFer without disruption of a functioning renal clinic.

  10. Obligatory provisions for nuclear power plants

    International Nuclear Information System (INIS)

    Cloosters, W.

    2008-01-01

    To cover the expenses associated with decommissioning and disposal of their nuclear power plants, German nuclear power plant operators set aside a total of more than EUR 30 billion and entered the respective provisions into their balance sheets. One point of eminent importance in this regard is the question whether these provisions are adequate in amount and permitted under accounting and tax laws. The other point to be considered is whether the funds will be available reliably if and when needed. Against the backdrop of these issues, the practice and importance of making these provisions are described. This is followed by an outline of the basic accounting and taxation aspects. It is seen that obligations under public law can be the basis of financial provisions only if there is a obligation sufficiently concrete in terms of time and object. The following examination of applicable obligations under the Atomic Energy Act incumbent upon nuclear power plant operators with regard to decommissioning and disposal results in the finding that such obligations are only partly regulated in the Atomic Energy Act, and that specifications in terms of time and purpose are insufficient. If the national practice of making financial provisions is to be put on a reliable basis, it is recommended to express the law on decommissioning and its mode of financing in more concrete terms in the Atomic Energy Act. In addition to unequivocal decommissioning and disposal obligations, the Atomic Energy Act should also incorporate regulations about financial provisions for decomissioning which are in need of more precise language. The present practice of making provisions is characterized by the risk that the funds necessary for planned decommissioning and disposal may not be available when needed. It is against this background that possible solutions reducing that risk are discussed. A recommendation is expressed to establish a public fund for decommissioning and disposal to which the

  11. Economic Loan Loss Provision and Expected Loss

    Directory of Open Access Journals (Sweden)

    Stefan Hlawatsch

    2010-10-01

    Full Text Available The intention of a loan loss provision is the anticipation of the loan's expected losses by adjusting the book value of the loan. Furthermore, this loan loss provision has to be compared to the expected loss according to Basel II and, in the case of a difference, liable equity has to be adjusted. This however assumes that the loan loss provision and the expected loss are based on a similar economic rationale, which is only valid conditionally in current loan loss provisioning methods according to IFRS. Therefore, differences between loan loss provisions and expected losses should only result from different approaches regarding the parameter estimation within each model and not due to different assumptions regarding the outcome of the model. The provisioning and accounting model developed in this paper overcomes the before-mentioned shortcomings and is consistent with an economic rationale of expected losses. Additionally, this model is based on a close-to-market valuation of the loan that is in favor of the basic idea of IFRS. Suggestions for changes in current accounting and capital requirement rules are provided.

    To explore the mechanism of traditional Chinese medicine (TCM) treatment according to syndrome differentiation in treating chronic obstructive pulmonary disease (COPD) by observing the changes of nuclear factor-kappaB (NF-kappaB) and gamma-glutamylcysteine synthetase (gamma-GCS) expression levels in rats. COPD model was established by modified method of combining fumigation and lipopolysaccharide (LPS) intra-tracheal dripping. Model rats were treated respectively for succesive 14 days according to their syndrome, that is, Xiaoqinglong Decoction to the rats of cold-phlegm accumulation in Fei, Maxing Shigan Decoction to those of heat-phlegm accumulation in Fei, Yupingfeng Decoction to those of Fei-qi deficiency, Liujunzi Decoction to those of Pi-qi deficiency, Renshen Gejie Decoction to those of Shen qi-deficiency. Besides, model rats in the model control group received 2mL normal saline daily, and no intervention was applied in the normal control group. The expression of gamma-GCS and NF-kappaB was detected by immunochemistry before and after treatment. Compared with that in the normal rats, the expressions of gamma-GCS and NF-kappaB in bronchial and alveolar epithelium of COPD rats before treatment were significantly higher, but the positive expression rates were lowered after treatment significantly (Psyndrome differentiation could rectify imbalance of oxidation/anti-oxidation and alleviate inflammatory reaction in COPD rats, thus to treat COPD effectively.

  14. Differential discriminator

    1981-01-01

    A principal flowsheet of a differential discriminator intended for operation in a spectrometric circuit with statistical time distribution of pulses is described. The differential discriminator includes four integrated discriminators and a channel of piled-up signal rejection. The presence of the rejection channel enables the discriminator to operate effectively at loads of 14x10 3 pulse/s. The temperature instability of the discrimination thresholds equals 250 μV/ 0 C. The discrimination level changes within 0.1-5 V, the level shift constitutes 0.5% for the filling ratio of 1:10. The rejection coefficient is not less than 90%. Alpha spectrum of the 228 Th source is presented to evaluate the discriminator operation with the rejector. The rejector provides 50 ns time resolution

    In patients with differentiated thyroid carcinoma it is indispensable to raise the values of TSH to determine thyroglobulin and to effect the total tracking with radioiodine. Traditionally to raise the endogenous TSH it is necessary to suspend the opotherapy during a prolonged time with the consistent hypothyroidism. The objective of this work is to increase the endogenous TSH, shortening the time of abstinence of opotherapy [es

    2013-03-01

    From the technical point of view different groups must be distinguished in the provision of orthopedic shoes for athletes. The one group encompasses athletes who are provided with insoles in the hope of improved comfort or better performance. The other group includes athletes with diseases or injuries of the lower limbs for whom the provision of appropriate shoes and insoles makes it possible for them to participate again actively in their chosen sport. In such cases one has to differentiate between the purely physical disorder of the foot and biomechanical disorders. For the first group the correct fitting of the shoe is the most important factor whereas in the second group attempts are made to correct and/or compensate for the deficit by means of insoles and wedges as well as supporting or bedding elements. The particular challenge for all such measures is to achieve an as small as possible impairment on the sport activity or, in the ideal cases, even to support it. © Georg Thieme Verlag KG Stuttgart · New York.

    Rapid scale-up of antiretroviral therapy (ART) in the context of financial and health system constraints has resulted in calls to maximize efficiency in ART service delivery. Adopting differentiated care models (DCMs) for ART could potentially be more cost-efficient and improve outcomes. However, no study comprehensively projects the cost savings across countries. We model the potential reduction in facility-level costs and number of health workers needed when implementing two types of DCMs while attempting to reach 90-90-90 targets in 38 sub-Saharan African countries from 2016 to 2020. We estimated the costs of three service delivery models: (1) undifferentiated care, (2) differentiated care by patient age and stability, and (3) differentiated care by patient age, stability, key vs. general population status, and urban vs. rural location. Frequency of facility visits, type and frequency of laboratory testing, and coverage of community ART support vary by patient subgroup. For each model, we estimated the total costs of antiretroviral drugs, laboratory commodities, and facility-level personnel and overhead. Certain groups under four-criteria differentiation require more intensive inputs. Community-based ART costs were included in the DCMs. We take into account underlying uncertainty in the projected numbers on ART and unit costs. Total five-year facility-based ART costs for undifferentiated care are estimated to be US$23.33 billion (95% confidence interval [CI]: $23.3-$23.5 billion). An estimated 17.5% (95% CI: 17.4%-17.7%) and 16.8% (95% CI: 16.7%-17.0%) could be saved from 2016 to 2020 from implementing the age and stability DCM and four-criteria DCM, respectively, with annual cost savings increasing over time. DCMs decrease the full-time equivalent (FTE) health workforce requirements for ART. An estimated 46.4% (95% CI: 46.1%-46.7%) fewer FTE health workers are needed in 2020 for the age and stability DCM compared with undifferentiated care. Adopting DCMs can

    1995-01-01

    Several large trials have shown that the risk of stroke in patients with non-valvar atrial fibrillation is reduced by treatment with warfarin. Implementing this research evidence requires not only an understanding of the trials' results and of the changes that they imply for clinicians' treatment decisions but also an appreciation of the organisation, quantity, and quality of services required to support these changes. Understanding of these implications is crucial for developing services that allow changes in practice to produce reductions in stroke incidence while minimising the risks of treatment. This article considers the developments in service provision that will probably be required to support the changes in clinical practice suggested by the trials' results. These services will be provided largely by doctors, and their development has implications for doctors in both primary and secondary care. Images FIG 1 PMID:7663216

  1. Bank loan loss provisions research: A review

    2017-09-01

    Full Text Available We review the recent academic and policy literature on bank loan loss provisioning. Among other things, we observe that there exist some interaction between LLPs and existing prudential, accounting, institutional, cultural, religious, tax and fiscal frameworks which differ across countries; and we find that managerial discretion in provisioning is strongly linked to income smoothing, capital management, signalling, tax management and other objectives. We also address several issues including the ethical dimensions of income smoothing, factors influencing income smoothing, methodological issues in LLP modelling and the dynamic loan loss provisioning experiment; which opens up several avenues for further research such as: finding a balance between sufficient LLPs which regulators want versus transparent LLPs which standard setters want; the sensitivity of abnormal LLPs to changes in equity; the persistence of abnormal LLPs following CEO exit; country-specific interventions that induce LLP procyclicality in emerging countries; the impact of Basel III on banks' provisioning discretion; LLP behaviour among systemic and non-systemic financial institutions; etc. We conclude that regulators need to pay attention to how much discretion lending institutions should have in determining reported provision estimates, and this has been a long standing issue.

  2. Methods of Services Provision in Slovak Towns

    Directory of Open Access Journals (Sweden)

    Emília Sičáková-Beblavá

    2009-07-01

    Full Text Available This article deals with the methods of services provision in Slovak towns.  It addresses decision-making concerning selected services provision, based on a transaction cost economic model. The article looks at five types of services from that point of view. These are core services, i.e., services that are provided in most Slovak towns, thereby allowing outcomes of decision-making to be compared, and services which can be outsourced according to transaction cost theory. Findings partially confirm the hypothesis: Slovak towns do outsource, though “insourcing” moderately prevails. However, a comparison of several research studies in the area indicates a trend towards higher outsourcing of such local services provision.  The findings show that public bodies do not always select the most suitable methods of services provision, as suggested by the transaction costs theory (the Brown-Potoski model. This indicates that it is not only economic models that influence decision-making concerning the organization of services provision in the Slovak towns.

  3. Treatment for moderate to severe atopic dermatitis in alpine and moderate maritime climates differentially affects helper T cells and memory B cells in children.

    Treatment of atopic dermatitis (AD) is focused on topical anti-inflammatory therapy, epidermal barrier repair and trigger avoidance. Multidisciplinary treatment in both moderate maritime and alpine climates can successfully reduce disease activity in children with AD. However, it remains unclear whether abnormalities in B cell and T cell memory normalize and whether this differs between treatment strategies. To determine whether successful treatment in maritime and alpine climates normalizes B- and T lymphocytes in children with moderate to severe AD. The study was performed in the context of a trial (DAVOS trial, registered at Current Controlled Trials ISCRTN88136485) in which eighty-eight children with moderate to severe AD were randomized to 6 weeks of treatment in moderate maritime climate (outpatient setting) or in the alpine climate (inpatient setting). Before and directly after treatment, disease activity was determined with SA-EASI and serum TARC, and T cell and B cell subsets were quantified in blood. Both treatment protocols achieved a significant decrease in disease activity, which was accompanied by a reduction in circulating memory Treg, transitional B cell and plasmablast numbers. Alpine climate treatment had a significantly greater effect on disease activity and was accompanied by a reduction in blood eosinophils and increases in memory B cells, CD8+ TemRO, CD4+ Tcm and CCR7+ Th2 subsets. Clinically successful treatment of AD induces changes in blood B- and T cell subsets reflecting reduced chronic inflammation. In addition, multidisciplinary inpatient treatment in the alpine climate specifically affects memory B cells, CD8+ T cells and Th2 cells. These cell types could represent good markers for treatment efficacy. © 2018 John Wiley & Sons Ltd.

    Methylphenidate and atomoxetine are effective in treating attention-deficit/hyperactivity disorder (ADHD) with underlying distinct pharmacological mechanisms. To relate neural mechanisms to clinical response, we conducted a comparative trial to differentiate the changes in brain activation of drug-naïve children with ADHD when performing neuropsychological tasks after 12 weeks of pharmacotherapy. We randomized 50 drug-naïve children with ADHD, aged 7-17, to treatment with methylphenidate (n=25) or atomoxetine (n=25). These children were scanned twice with functional magnetic resonance imaging (fMRI) during the counting Stroop task before and after treatment. Focused attention and impulsivity were assessed twice by using the Conner's Continuous Performance Test (CCPT). The final sample for fMRI analysis comprised 20 in the methylphenidate group and 22 in the atomoxetine group. Atomoxetine decreased activations in the dorsal anterior cingulate cortex and dorsolateral prefrontal cortex, which correlated with improvement in focused attention assessed by the CCPT. In contrast, methylphenidate increased activations in the inferior frontal gyrus, which correlated with the decreasing severity of impulsivity assessed by the CCPT. The current findings suggest that differential therapeutic effects on neuronal changes induced by 12-week treatment atomoxetine and methylphenidate may contribute to behavioral improvement.

    2015-06-01

    After 40 years of monitoring cleft palate treatment results with extensive objective records of cephaloradiographs, dental casts, and photographs, it became apparent that patients with the same cleft type who received the same treatment at approximately the same age were obtaining different results. An extensive review of cleft palate surgical, orthodontic, facial, and palatal longitudinal growth studies was undertaken to determine the critical physical difference between these patients that determined why some treatments succeeded while others failed. Treatment should be based on performing staged palatal surgery between 18 and 24 months when the palatal surface area to cleft space size is approximately 15% to 20%. Presurgical orthopedics with a gingivoperiosteoplasty causes midfacial deformities. Even though patients have the same cleft type and have received the same surgical treatment, usually between 18 and 24 months, the ratio of cleft and palatal size of 15% to 20% is critical to obtain good palatal development.

    Ewing's sarcoma is a pediatric tumor that mainly occurs in soft tissues and bones. Malignant characteristics of Ewing's sarcoma are correlated with expression of EWS oncogene. We achieved knockdown of EWS expression using a plasmid vector encoding EWS short hairpin RNA (shRNA) to increase anti-tumor mechanisms of taxifolin (TFL), a new flavonoid, in human Ewing's sarcoma cells in culture and animal models. Immunofluorescence microscopy and flow cytometric analysis showed high expression of EWS in human Ewing's sarcoma SK-N-MC and RD-ES cell lines. EWS shRNA plus TFL inhibited 80% cell viability and caused the highest decreases in EWS expression at mRNA and protein levels in both cell lines. Knockdown of EWS expression induced morphological features of differentiation. EWS shRNA plus TFL caused more alterations in molecular markers of differentiation than either agent alone. EWS shRNA plus TFL caused the highest decreases in cell migration with inhibition of survival, angiogenic and invasive factors. Knockdown of EWS expression was associated with removal of DNA methylation from p53 promoter, promoting expression of p53, Puma, and Noxa. EWS shRNA plus TFL induced the highest amounts of apoptosis with activation of extrinsic and intrinsic pathways in both cell lines in culture. EWS shRNA plus TFL also inhibited growth of Ewing's sarcoma tumors in animal models due to inhibition of differentiation inhibitors and angiogenic and invasive factors and also induction of activation of caspase-3 for apoptosis. Collectively, knockdown of EWS expression increased various anti-tumor mechanisms of TFL in human Ewing's sarcoma in cell culture and animal models.

    2018-02-01

    The Sustainable Development Goals (SDGs) present a groundbreaking global development agenda to protect the most vulnerable. Adolescents living with HIV in Sub-Saharan Africa continue to experience extreme health vulnerabilities, but we know little about the impacts of SDG-aligned provisions on their health. This study tests associations of provisions aligned with five SDGs with potential mortality risks. Clinical and interview data were gathered from N = 1060 adolescents living with HIV in rural and urban South Africa in 2014 to 2015. All ART-initiated adolescents from 53 government health facilities were identified, and traced in their communities to include those defaulting and lost-to-follow-up. Potential mortality risk was assessed as either: viral suppression failure (1000+ copies/ml) using patient file records, or adolescent self-report of diagnosed but untreated tuberculosis or symptomatic pulmonary tuberculosis. SDG-aligned provisions were measured through adolescent interviews. Provisions aligned with SDGs 1&2 (no poverty and zero hunger) were operationalized as access to basic necessities, social protection and food security; An SDG 3-aligned provision (ensure healthy lives) was having a healthy primary caregiver; An SDG 8-aligned provision (employment for all) was employment of a household member; An SDG 16-aligned provision (protection from violence) was protection from physical, sexual or emotional abuse. Research partners included the South African national government, UNICEF and Pediatric and Adolescent Treatment for Africa. 20.8% of adolescents living with HIV had potential mortality risk - i.e. viral suppression failure, symptomatic untreated TB, or both. All SDG-aligned provisions were significantly associated with reduced potential mortality risk: SDG 1&2 (OR 0.599 CI 0.361 to 0.994); SDG 3 (OR 0.577 CI 0.411 to 0.808); SDG 8 (OR 0.602 CI 0.440 to 0.823) and SDG 16 (OR 0.686 CI 0.505 to 0.933).

    Differential diagnosis is the focal point of this richly illustrated atlas intended for experienced mammographers. Mammographs of different histology but with similar features are presented side by side for easy comparison; pinpointed questions accompanying the pictures are guiding the reader to systematically develop the differential dioagnosis, with correct answers being given on the next pages together with characteristic and typical pictures explaining the correct and false diagnoses, including clinical photographs and sonographic images. Unusual mammographic findings are discussed in a separate chapter, and other chapters deal with the history of senology and with problems encountered in examinations for early diagnosis, as reported in the German Mammography Study and in international screening projects. The concluding chapter deals with legal aspects such as liability of the physician in case of missed detection of tumors, explaining the most frequent causes of false diagnosis as a guide to preventing errors, and giving practical hints and information for the event of damages being claimed from a physician.

    2009-01-01

    Studies have reported conflicting findings regarding the impact on treatment for eating disorder patients comorbidly diagnosed with borderline personality disorder. The current investigation sought to investigate whether individuals diagnosed with an eating disorder vs. those comorbidly diagnosed with an eating disorder and borderline personality disorder differ on measures of eating disorders symptoms and/or general distress over the course of treatment. In light of the success of DBT in treating individuals diagnosed with borderline personality disorder, a group known to have considerable difficulties in regulating affect, the current study also sought to examine whether these two groups would differ on expectancies to regulate affect over the course of DBT-informed treatment. Results indicated that while a comorbid diagnosis of borderline personality disorder did not impact eating disorder treatment outcomes, those comorbidly diagnosed did present overall with higher levels of general distress and psychological disturbance. With respect to affect regulation, results indicated that at the beginning of treatment, eating disordered individuals who carried a comorbid diagnosis of BPD were significantly less able to regulate affect than patients without a comorbid borderline diagnosis. However, at the end of treatment there was no statistically significant difference between the two groups. The role of affect regulation in treating eating disordered individuals with a comorbid borderline personality disorder diagnosis is discussed.

  5. Mitigating Provider Uncertainty in Service Provision Contracts

    Science.gov (United States)

    Smith, Chris; van Moorsel, Aad

    Uncertainty is an inherent property of open, distributed and multiparty systems. The viability of the mutually beneficial relationships which motivate these systems relies on rational decision-making by each constituent party under uncertainty. Service provision in distributed systems is one such relationship. Uncertainty is experienced by the service provider in his ability to deliver a service with selected quality level guarantees due to inherent non-determinism, such as load fluctuations and hardware failures. Statistical estimators utilized to model this non-determinism introduce additional uncertainty through sampling error. Inability of the provider to accurately model and analyze uncertainty in the quality level guarantees can result in the formation of sub-optimal service provision contracts. Emblematic consequences include loss of revenue, inefficient resource utilization and erosion of reputation and consumer trust. We propose a utility model for contract-based service provision to provide a systematic approach to optimal service provision contract formation under uncertainty. Performance prediction methods to enable the derivation of statistical estimators for quality level are introduced, with analysis of their resultant accuracy and cost.

    2014-09-01

    The consequences of inflammatory arthritis can include depression, anxiety and low mood, reducing patients' quality of life and increasing pressure on the healthcare system. Treatment guidelines recommend psychological support, but data are lacking on the provision available. A postal survey concerning psychological support provision was sent to rheumatology units in 143 acute trusts across England. Nurses from 73 rheumatology units (51%) responded. Overall, 73% rated their unit's psychological support provision as 'inadequate' and only 4% rated it as 'good'. Few units believed that psychological support did not fall within their remit (12%), yet only 8% had a psychologist in the team. Most units (68%) did not routinely screen patients to identify psychological difficulties. Referral to other service providers was reported in 42% of units, with 3% very satisfied with this provision. Within units, services containing elements of psychological support ranged from occupational therapy (81%) to psychology/counselling (14%). Psychological approaches used by team members ranged from shared decision making (77%) to cognitive-behavioural approaches (26%). The current barriers to providing psychological support were lack of clinical time and available training (86% and 74%, respectively), and delivery costs (74%). Future facilitators included management support (74%) and availability of skills training (74%). Rheumatology units viewed psychological support provision as part of their remit but rated their overall provision as inadequate, despite some team members using psychological skills. To improve provision, clinicians' training needs must be addressed and organizational support generated, and further research needs to define adequate psychological support provision from the patient perspective. © 2014 The Authors.

    Recent evidence underlines the crucial role of neuronal cytoskeleton in the pathophysiology of psychiatric diseases. In this line, the deletion of STOP/MAP6 (Stable Tubule Only Polypeptide), a microtubule-stabilizing protein, triggers various neurotransmission and behavioral defects, suggesting that STOP knockout (KO) mice could be a relevant experimental model for schizoaffective symptoms. To establish the predictive validity of such a mouse line, in which the brain serotonergic tone is dramatically imbalanced, the effects of a chronic fluoxetine treatment on the mood status of STOP KO mice were characterized. Moreover, we determined the impact, on mood, of a chronic treatment by epothilone D, a taxol-like microtubule-stabilizing compound that has previously been shown to improve the synaptic plasticity deficits of STOP KO mice. We demonstrated that chronic fluoxetine was either antidepressive and anxiolytic, or pro-depressive and anxiogenic, depending on the paradigm used to test treated mutant mice. Furthermore, control-treated STOP KO mice exhibited paradoxical behaviors, compared with their clear-cut basal mood status. Paradoxical fluoxetine effects and control-treated STOP KO behaviors could be because of their hyper-reactivity to acute and chronic stress. Interestingly, both epothilone D and fluoxetine chronic treatments improved the short-term memory of STOP KO mice. Such treatments did not affect the serotonin and norepinephrine transporter densities in cerebral areas of mice. Altogether, these data demonstrated that STOP KO mice could represent a useful model to study the relationship between cytoskeleton, mood, and stress, and to test innovative mood treatments, such as microtubule-stabilizing compounds. © 2012 The Authors Journal of Neurochemistry © 2012 International Society for Neurochemistry.

  19. Rod rotation and differential rod contouring followed by direct vertebral rotation for treatment of adolescent idiopathic scoliosis: effect on thoracic and thoracolumbar or lumbar curves assessed with intraoperative computed tomography.

    Although direct vertebral rotation (DVR) is now used worldwide for the surgical treatment of adolescent idiopathic scoliosis (AIS), the benefit of DVR in reducing vertebral body rotation in these patients has not been determined. We investigated a possible additive effect of DVR on further reduction of vertebral body rotation in the axial plane following intraoperative rod rotation or differential rod contouring in patients undergoing surgical treatment for AIS. The study was a prospective computed tomography (CT) image analysis. We analyzed the results of the two intraoperative procedures in 30 consecutive patients undergoing surgery for AIS (Lenke type I or II: 15; Lenke type V: 15). The angle of reduction of vertebral body rotation taken by intraoperative CT scan was measured and analyzed. Pre- and postoperative responses to the Scoliosis Research Society 22 Questionnaire (SRS-22) were also analyzed. To analyze the reduction of vertebral body rotation with rod rotation or DVR, intraoperative cone-beam CT scans of the three apical vertebrae of the major curve of the scoliosis (90 vertebrae) were taken pre-rod rotation (baseline), post-rod rotation with differential rod contouring, and post-DVR in all patients. The angle of vertebral body rotation in these apical vertebrae was measured and analyzed for statistical significance. Additionally, differences between thoracic curve scoliosis (Lenke type I or II; 45 vertebrae) and thoracolumbar or lumbar curve scoliosis (Lenke type V; 45 vertebrae) were analyzed. Pre- and postoperative SRS-22 scores were evaluated in all patients. The mean (90 vertebrae) vertebral body rotation angles at baseline, post-rod rotation or differential rod contouring, and post-rod rotation or differential rod contouring or post-DVR were 17.3°, 11.1°, and 6.9°, respectively. The mean reduction in vertebral body rotation with the rod rotation technique was 6.8° for thoracic curves and 5.7° for thoracolumbar or lumbar curves (pself

    Anxiety sensitivity (AS), defined as the extent to which individuals believe anxiety and anxiety-related sensations have harmful consequences, may play an important explanatory role in the relation between emotional non-acceptance and the expression of traumatic stress symptoms among trauma-exposed smokers. This investigation examined whether lower-order dimensions of AS (cognitive, physical, and social concerns) differentially explain the relation between emotional non-acceptance and post-traumatic stress (PTS) symptom clusters (re-experiencing, avoidance, hyperarousal) among trauma-exposed daily smokers (N = 169, 46% female; Mage = 41, SD = 12.3). AS and its lower-order facets of cognitive and social concerns were found to mediate the relations between emotional non-acceptance and avoidance and hyperarousal PTS symptoms. Using a multiple mediation model, the mediational effect of AS cognitive concerns for the relation between emotional non-acceptance and post-traumatic avoidance symptoms was found to be uniquely evident relative to social and physical concerns. All observed AS effects were evident above and beyond the variance accounted for by gender, number of traumatic event exposure types, negative affectivity, number of cigarettes smoked per day, and alcohol use problems. The present findings suggest cognitive-based AS concerns may play a mechanistic role in the relation between emotional non-acceptance and certain PTS symptoms among trauma-exposed daily smokers.

    Full Text Available Diabetes is one of the most prevalent, costly, and debilitating diseases in the world. Pancreas and islet transplants have shown success in re-establishing glucose control and reversing diabetic complications. However, both are limited by donor availability, need for continuous immunosuppression, loss of transplanted tissue due to dispersion, and lack of vascularization. To overcome the limitations of poor islet availability, here, we investigate the potential of bone marrow–derived mesenchymal stem cells differentiated into islet-like insulin-producing aggregates. Islet-like insulin-producing aggregates, characterized by gene expression, are shown to be similar to pancreatic islets and display positive immunostaining for insulin and glucagon. To address the limits of current encapsulation systems, we developed a novel three-dimensional printed, scalable, and potentially refillable polymeric construct (nanogland to support islet-like insulin-producing aggregates’ survival and function in the host body. In vitro studies showed that encapsulated islet-like insulin-producing aggregates maintained viability and function, producing steady levels of insulin for at least 4 weeks. Nanogland—islet-like insulin-producing aggregate technology here investigated as a proof of concept holds potential as an effective and innovative approach for diabetes cell therapy.

    Determination of stability limits, mineralogical changes and thermal reaction of serpentine minerals are very important for the investigation of magmatism, mechanism and depth of plates of subduction. During the subduction process, serpentine (Lizardite) minerals will release their water due to thermal reactions. This dehydration can play an important role in volcanism processes related to the subduction, In this study, serpentine minerals (Lizardite) collected from the Neyriz Ophiolite Complex were dehydrated under the constant atmospheric pressure. These mineralogical changes were determined by X-Ray diffraction and differential thermal analysis-thermal gravimetric analyses methods. This study shows natural lizardites that heated for about one hour is stable up to 550 d eg C . Dehydration reactions on lizardite started at approximately between 100 to 150 d eg C and dehydroxylation reactions started at approximately 550-690 d eg C . As a result of thermal reaction, the decomposition of lizardite will take place and then changes in to olivine (forsterite). Crystallization of olivine (forsterite) will start at 600 d eg C . This mineral is stable up to 700 d eg C and then crystallization of enstatite will start at 700 d eg C . During this dehydration and crystallization reaction, amorphous processes will start at 600 d eg C and some amount water and silica will release.

    Full Text Available Niemann-Pick disease type C (NPC disease is a neurodegenerative lysosomal storage disease caused by mutations in the NPC1 or NPC2 genes. Liver disease is also a common feature of NPC that can present as cholestatic jaundice in the neonatal period. Liver enzymes can remain elevated above the normal range in some patients as they age. We recently reported suppression of the P450 detoxification system in a mouse model of NPC disease and also in post-mortem liver from NPC patients. We demonstrated the ability of the hydrophobic bile acid ursodeoxycholic acid (UDCA (3α, 7β-dihydroxy-5β-cholanic acid to correct the P450 system suppression. UDCA is used to treat several cholestatic disorders and was tested in NPC due to the P450 system being regulated by bile acids. Here, we compare the effect of UDCA and cholic acid (CA, another bile acid, in the NPC mouse model. We observed unexpected hepatotoxicity in response to CA treatment of NPC mice. No such hepatotoxicity was associated with UDCA treatment. These results suggest that CA treatment is contraindicated in NPC patients, whilst supporting the use of UDCA as an adjunctive therapy in NPC patients.

    The effect of 8-methoxypsoralen (8-MOP, 5 x 10 -5 M), near UV-light of 365 nm wavelength (UVA, 1.5 J/cm 2 ) and the combination of both (PUVA treatment) were studied on lymphocytes in vitro taken from healthy persons and patients with psoriasis vulgaris and psoriasis arthritis (psoriasis arthropathica). Chromosomes isolated from cell nuclei were visualized by means of Giemsa staining technique and analyzed for induction of chromosomal defects, i.e. premature centromere division (PCD), major coiling (MC), and formation of gaps and fragile sites. Exposure of nonpsoriatic lymphocytes to 8-MOP, UVA or PUVA increased the rate of PCD or MC generation. In experiments with psoriatic lymphocytes a much weaker effect was found, with a moderate increase of PCD and MC after UVA or PUVA treatment in the case of psoriasis vulgaris, and of MC after UVA treatment of psoriasis arthritis. On the average the number of chromosomes per metaphase plate displaying PCD did not exceed 10. No indication was obtained for the preference of certain chromosome groups or the appearance of 'fragile sites'. Under all experimental conditions the number of chromosome gaps ranged in the order of their spontaneous induction. The findings suggest PCD and MC investigations as possible sensitive tools for diagnosing latent psoriasis and for refined analysis of psoriatic cells or chromosomes. (author)

    The backdrop to this article is provided by the Better Health, Better Care Action Plan (Scottish Government, 2007), Section 1 of which is entitled 'Towards a Mutual NHS'. According to Better Health, Better Care (Scottish Government, 2007: 5): 'Mutual organisations are designed to serve their members. They are designed to gather people around a common sense of purpose. They are designed to bring the organisation together in what people often call "co-production."' The aim of this article is to précis the current knowledge of mutuality in the provision of Scottish healthcare. In detail, it will: introduce the 'mutual' organisation; offer a historical perspective of mutuality; suggest why healthcare mutuality is important; and briefly, detail the differences in mutual health-care policy in England and Scotland. It is hoped that this analysis will help researchers and practitioners alike appreciate further the philosophy of mutuality in the provision of Scottish healthcare. © The Author(s) 2015.

    In this research, we consider the spares provisioning problem, where a finite population of homogeneous machines are being deployed to meet a constant demand. While a machine is operating, it could become inoperable due to the failure of a critical built-in part in the machine. Before repairs on the machine can be initiated, however, a replacement part must be obtained. If a replacement part is available from stock, the machine is immediately transferred to the repair subsystem...

    Electricity provision touches upon every facet of life in OECD and non-OECD countries alike, and choosing how this electricity is generated - whether from fossil fuels, nuclear energy or renewables - affects not only economic outcomes but individual and social well-being in the broader sense. Research on the overall costs of electricity is an ongoing effort, as only certain costs of electricity provision are perceived directly by producers and consumers. Other costs, such as the health impacts of air pollution, damage from climate change or the effects on the electricity system of small-scale variable production are not reflected in market prices and thus diminish well-being in unaccounted for ways. Accounting for these social costs in order to establish the full costs of electricity provision is difficult, yet such costs are too important to be disregarded in the context of the energy transitions currently under way in OECD and NEA countries. This report draws on evidence from a large number of studies concerning the social costs of electricity and identifies proven instruments for internalising them so as to improve overall welfare. The results outlined in the report should lead to new and more comprehensive research on the full costs of electricity, which in turn would allow policy makers and the public to make better informed decisions along the path towards fully sustainable electricity systems

    Valdmanis, Vivian; DeNicola, Arianna; Bernet, Patrick

    2015-12-01

    In this paper, we assess the capacity of Florida's public health departments. We achieve this by using bootstrapped data envelopment analysis (DEA) applied to Johansen's definition of capacity utilization. Our purpose in this paper is to measure if there is, theoretically, enough excess capacity available to handle a possible surge in the demand for primary care services especially after the implementation of the Affordable Care Act that includes provisions for expanded public health services. We measure subunit service availability using a comprehensive data source available for all 67 county health departments in the provision of diagnostic care and primary health care. In this research we aim to address two related research questions. First, we structure our analysis so as to fix budgets. This is based on the assumption that State spending on social and health services could be limited, but patient needs are not. Our second research question is that, given the dearth of primary care providers in Florida if budgets are allowed to vary is there enough medical labor to provide care to clients. Using a non-parametric approach, we also apply bootstrapping to the concept of plant capacity which adds to the productivity research. To preview our findings, we report that there exists excess plant capacity for patient treatment and care, but question whether resources may be better suited for more traditional types of public health services.

    Service provision patterns may be influenced not only by clinical oral health status leading to a diagnosis and treatment plan, but also by other variables such as patient characteristics. The main aim of this study was to investigate whether associations between services provided and patient factors would persist after controlling for the main presenting diagnosis or condition. A random sample of dentists surveyed in 1993-94 provided a response rate of 74%. Private general practitioners recorded service provision data from logs of 1-2 typical days of practice. Caries (26.5%) was the most prevalent diagnosis, followed by recall/maintenance care (19.0%), pulpal/periapical infection (10.9%), and failed restorations (10.4%). Diagnoses were associated with variation in the percentage of patients receiving services in main areas of service, and also with insurance status, sex and age distributions of patients, and type of visit (chi-square; Pservices indicated statistically significant associations with patient characteristics and diagnosis categories. Controlling for diagnosis, uninsured patients and those visiting for emergencies had less favourable service patterns (e.g., higher odds of extractions, but lower odds of preventive and crown and bridge services) compared to patients who had dental insurance or visited for check-ups or other non-emergency dental problems. The influence of these factors on services provided has implications of public health importance in terms of appropriateness of care and social inequality.

    We selected 92 patients without anti thyroglobulin antibodies (TgAb), in whom thyroglobulin (Tg) after L-thyroxin withdrawal was undetectable ( 1.5 cm; and lymph nodes metastases in 43 (46.7%), local invasion in 26 (28.2%) or distant metastases in 23 (25%). Control whole-body scanning was negative in 78.2% of the cases and showed cervical uptake in the others. Cases presenting thyroid bed uptake in the absence of tumor recurrence did not receive radioiodine and Tg remained undetectable one year after the initial evaluation in all. Cervical uptake was not observed in 4/13 cases on repeated scan. In contrast, even in the absence of uptake and with undetectable Tg, 7 patients with recurrence confirmed by ultrasound (US) received surgical treatment. US showed 92.8% sensitivity for the detection of local-regional disease. The present study suggests that even moderate/high-risk patients without TgAb and with undetectable T g levels (off T 4 ) do not require radioiodine scanning after initial treatment and can be evaluated by cervical US.

    Under the framework of Basel II, banks which adopt the internal ratings-based approach will be required to compare their actual provisions with expected losses. Any shortfall (i.e., the expected loss exceeds the provision) should be deducted from capital of the bank. It is therefore important to ensure banks make adequate provisions against expected losses. In addition, both sound policy and the Banking Ordinance require banks to take a forward-looking view of provisions. These requirements r...

  5. Differentiated thyroid cancer (papillary). Brain tumor metastasis as clinical onset. surgical treatment and "1"3"1I. 8 years disease-free

    International Nuclear Information System (INIS)

    Mena, D.; Pena, M.; Alvarez, L.; García del Rio, H.; Bruno, O.

    2015-01-01

    Introduction: The differentiated thyroid cancer is the most common endocrine neoplasia. The major manifestation belongs to the papillary variant (65-90%). The prognosis tends to be very favorable, with a mortality rate of 1.8 % and a disease-free rate up to 10 years of around 90-95 %. The distant metastasis in brain accounts for 0.1-5 %. There are no established protocols for the management of brain metastasis. Therapeutic options are: surgery, stereotactic radiotherapy / radiosurgery, and "1"3"1I. The successful management of this case is an option for brain metastasis from thyroid papillary carcinoma. Case report: A 77 year-old female begins with double vision (diplopia). She underwent twice a surgery for brain tumor with a histopathological report on thyroid papillary tissue. The endocrine evaluation determines euthyroid state except thyroglobulin (TG) 2300 ng/ml. Total thyroidectomy with classic thyroid papillary carcinoma. A diagnostic "1"3"1I scan after surgery shows for first time brain metastasis uptake. The patient receives 25 mCi of "1"3"1I as initial therapeutic dose, and subsequent therapeutic doses (50, 50, 75, 75, 50 mCi) in 2 years, in accordance with the evolution of magnetic resonance, clinic, endocrine lab, hematological analysis, and "1"3"1I scintigraphy, that shows the possible remission of the disease. The follow-up was carried out by means of a clinical control, thyroglobulin values, U.S., "1"3"1I scans, and magnetic resonance. The patient is at the present time over 11 years survival and 8 years disease-free. Discussion: Even though the distant metastasis is not very common in brain and is generally associated with aggressive variants of tumor, our case started with a metastatic brain tumor in an euthyroid patient with no thyroid pathology background and with low-risk post-thyroidectomy criterion. The "1"3"1I scan turned positive in brain metastasis when the patient was thyroidectomized. This detail must be considered important, since it

    Full Text Available Abnormal uterine bleeding may be acute or chronic accounting for up to 30% of outpatient visits to gynecologists. Hyperprolactinemia is one of the most common endocrine disorders associated with ovulatory dysfunction that results in menstrual irregularities. Prior to initiating treatment, the various causes (physiologic, pathologic, pharmacologic, or idiopathic of hyperprolactinemia must be elucidated. Prolactin is a stress hormone that increases in response to stressful conditions; therefore, while collecting samples it is necessary to reduce venipuncture stress. A thorough patient history and physical examination will help to identify the cause and to direct therapy. Imaging results must always be assessed along with a patient’s clinical history and biochemical parameters when a pituitary tumor is suspected. Magnetic resonance imaging is the method of choice for the diagnosis of microprolactinomas and macroprolactinomas in both initial assessment and follow-up. Several drugs may cause a significant increase in serum prolactin concentration. If clinically feasible, the drug should be discontinued; if this is not possible, it should be substituted with a drug of similar action that does not cause hyperprolactinemia. Prolactinomas are the most common cause of pituitary adenomas affecting women of fertile age leading to significant elevations in prolactin that warrant treatment. Idiopathic hyperprolactinemia may be observed in the presence of elevated serum prolactin levels and in the absence of any other recognized cause of increased prolactin secretion. Dopamine agonists are the mainstay of therapy in prolactinomas and symptomatic idiopathic hyperprolactinemia because they normalize serum prolactin, effectively shrink prolactinomas and normalize gonadal function (i.e. menstruation.

Chronic inflammation has been linked to tumorigenesis, with a key role for the cyclooxygenase-2 (COX-2) enzyme. Diclofenac, a COX-2 inhibitor and non-steroidal anti-inflammatory drug, currently is prescribed to patients as a short-term therapeutic agent to induce SCC precursor lesion regression. However, its efficacy as a preventative agent in patients without evidence of precursor lesions but with significant UVB-induced cutaneous damage has not been explored. We previously demonstrated in a murine model of UVB-induced skin carcinogenesis that when exposed to equivalent UVB doses, male mice had lower levels of inflammation but developed increased tumor multiplicity, burden and grade compared with female mice. Because of the discrepancy in the degree of inflammation between male and female skin, we sought to determine if topical treatment of previously damaged skin with an anti-inflammatory COX-2 inhibitor would decrease tumor burden and if it would be equally effective in the sexes. Our results demonstrated that despite observed sex differences in the inflammatory response, prolonged topical diclofenac treatment of chronically UVB-damaged skin effectively reduced tumor multiplicity in both sexes. Unexpectedly, tumor burden was significantly decreased only in male mice. Our data suggest a new therapeutic use for currently available topical diclofenac as a preventative intervention for patients predisposed to cutaneous SCC development before lesions appear.

    Individuals with public speaking anxiety (PSA) experience fear and avoidance that can cause extreme distress, impaired speaking performance, and associated problems in psychosocial functioning. Most extant interventions for PSA emphasize anxiety reduction rather than enhancing behavioral performance. We compared the efficacy of two brief cognitive-behavioral interventions, a traditional cognitive-behavior treatment (tCBT) and an acceptance-based behavior treatment (ABBT), on public speaking performance and anxiety in a clinical sample of persons with PSA. The effects of treatment on prefrontal brain activation were also examined. Participants (n = 21) were randomized to 90 min of an ABBT or a tCBT intervention. Assessments took place at pre- and post-treatment and included self-rated anxiety and observer-rated performance measures, a behavioral assessment, and prefrontal cortical activity measurements using functional near-infrared spectroscopy (fNIRS). Exploratory results indicated that participants in the ABBT condition experienced greater improvements in observer-rated performance relative to those in the tCBT condition, while those in the tCBT condition experienced greater reductions in subjective anxiety levels. Individuals in the ABBT condition also exhibited a trend toward greater treatment-related reductions in blood volume in the left dorsolateral prefrontal cortex relative to those who received tCBT. Overall, these findings preliminarily suggest that acceptance-based treatments may free more cognitive resources in comparison with tCBT, possibly resulting in greater improvements in objectively rated behavioral performances for ABBT interventions. © The Author(s) 2016.

    Although diarrheal mortality is cheaply preventable with oral rehydration therapy (ORT), over 700,000 children die of diarrhea annually and many health providers fail to treat diarrheal cases with ORT. Provision of ORT may differ between for-profit and public providers. This study used Demographic and Health Survey data from 19,059 children across 29 countries in sub-Saharan Africa from 2003 to 2011 to measure differences in child diarrhea treatment between private for-profit and public health providers. Differences in treatment provision were estimated using probit regression models controlling for key confounders. For-profit providers were 15% points less likely to provide ORT (95% confidence interval [CI] 13-17) than public providers and 12% points more likely to provide other treatments (95% CI 10-15). These disparities in ORT provision were more pronounced for poorer children in rural areas. As private healthcare in sub-Saharan Africa continues to expand, interventions to increase private sector provision of ORT should be explored.

    In Germany the latest discussion on the cost of nuclear phase-out, dismantling and waste disposal has shown that the provision of capital by the concerned companies for these challenges and the actual regulations are not sufficient for a long-term financing security. The study presents a reform concept including the need of improved transparency on the provision of capital, a differentiated financial statement, the introduction of a stock under public law for insolvency protection including a financing responsibility for the companies and subsequent payments in case of cost increase, and an increase of protection in case of insolvency.

    Platelet-rich plasma (PRP) is widely used to treat tendon injuries in clinics. These PRP preparations often contain white blood cells or leukocytes, and the precise cellular effects of leukocyte-rich PRP (L-PRP) on tendons are not well defined. Therefore, in this study, we determined the effects of L-PRP on tendon stem/progenitor cells (TSCs), which play a key role in tendon homeostasis and repair. TSCs isolated from the patellar tendons of rabbits were treated with L-PRP or P-PRP (pure PRP without leukocytes) in vitro, followed by measuring cell proliferation, stem cell marker expression, inflammatory gene expression, and anabolic and catabolic protein expression by using immunostaining, quantitative real-time polymerase chain reaction, Western blot, and enzyme-linked immunosorbent assay, respectively. Cell proliferation was induced by both L-PRP and P-PRP in a dose-dependent manner with maximum proliferation at a 10 % PRP dose. Both PRP treatments also induced differentiation of TSCs into active tenocytes. Nevertheless, the two types of PRP largely differed in several effects exerted on TSCs. L-PRP induced predominantly catabolic and inflammatory changes in differentiated tenocytes; its treatment increased the expression of catabolic marker genes, matrix metalloproteinase-1 (MMP-1), MMP-13, interleukin-1beta (IL-1β), IL-6 and tumor necrosis factor-alpha (TNF-α), and their respective protein expression and prostaglandin E2 (PGE 2) production. In contrast, P-PRP mainly induced anabolic changes; that is, P-PRP increased the gene expression of anabolic genes, alpha-smooth muscle actin (α-SMA), collagen types I and III. These findings indicate that, while both L-PRP and P-PRP appear to be "safe" in inducing TSC differentiation into active tenocytes, L-PRP may be detrimental to the healing of injured tendons because it induces catabolic and inflammatory effects on tendon cells and may prolong the effects in healing tendons. On the other hand, when P-PRP is used to

    It has been recently shown that within heterogeneous tumor masses a small population of less differentiated transformed cells has the ability to self-renew and regenerate the bulk of the tumor. Their similarities with normal stem cells in terms of gene expression patterns, proliferative capacity and surface markers rendered them the name of cancer stem-like cells (CSC), and these are thought to be the tumor initiating cells (TIC). Their limited susceptibility to classical anti-tumor therapy help explain the high incidence of cancer-treatment relapses observed in selected malignancies. Much effort is being directed towards the understanding of factors that maintain CSC survival and their self-renewal capacity, with the goal that these same signaling pathways can be harnessed for treatments that aim at inducing CSC differentiation. This review will discuss the CSC theory, its implications, potential signaling pathways responsible for maintaining their undifferentiated and pluripotent states, and new venues being explored to target these cells in modern cancer therapy.

  1. Differential diagnosis of hyponatraemia.

    2012-03-01

    The appropriate management of hyponatraemia is reliant on the accurate identification of the underlying cause of the hyponatraemia. In the light of evidence which has shown that the use of a clinical algorithm appears to improve accuracy in the differential diagnosis of hyponatraemia, the European Hyponatraemia Network considered the use of two algorithms. One was developed from a nephrologist\\'s view of hyponatraemia, while the other reflected the approach of an endocrinologist. Both of these algorithms concurred on the importance of assessing effective blood volume status and the measurement of urine sodium concentration in the diagnostic process. To demonstrate the importance of accurate diagnosis to the correct treatment of hyponatraemia, special consideration was given to hyponatraemia in neurosurgical patients. The differentiation between the syndrome of inappropriate antidiuretic hormone secretion (SIADH), acute adrenocorticotropic hormone (ACTH) deficiency, fluid overload and cerebral salt-wasting syndrome was discussed. In patients with SIADH, fluid restriction has been the mainstay of treatment despite the absence of an evidence base for its use. An approach to using fluid restriction to raise serum tonicity in patients with SIADH and to identify patients who are likely to be recalcitrant to fluid restriction was also suggested.

    In the past, mental health services in Sri Lanka were limited to tertiary-care institutions, resulting in a large treatment gap. Starting in 2000, significant efforts have been made to reconfigure service provision and to integrate mental health services with primary health care. This approach was supported by significant political commitment to establishing island-wide decentralized mental health care in the wake of the 2004 tsunami. Various initiatives were consolidated in The mental health policy of Sri Lanka 2005-2015, which called for implementation of a comprehensive community-based, decentralized service structure. The main objectives of the policy were to provide mental health services of good quality at primary, secondary and tertiary levels; to ensure the active involvement of communities, families and service users; to make mental health services culturally appropriate and evidence based; and to protect the human rights and dignity of all people with mental health disorders. Significant improvements have been made and new cadres of mental health workers have been introduced. Trained medical officers (mental health) now provide outpatient care, domiciliary care, mental health promotion in schools, and community mental health education. Community psychiatric nurses have also been trained and deployed to supervise treatment adherence in the home and provide mental health education to patients, their family members and the wider community. A total of 4367 mental health volunteers are supporting care and raising mental health literacy in the community. Despite these important achievements, more improvements are needed to provide more timely intervention, combat myths and stigma, and further decentralize care provision. These, and other challenges, will be targeted in the new mental health policy for 2017-2026.

    Oxidative stress is implicated in the pathogenesis and/or complications of hypertension and/or diabetes mellitus. A combination of these disorders increases the risk of developing cardiovascular events. This study investigated the effects of streptozotocin (60 mg/kg; ip)-induced diabetes on blood pressure, oxidative stress and effects of honey on these parameters in the kidneys of streptozotocin-induced diabetic Wistar-Kyoto (WKY) and spontaneously hypertensive rats (SHR). Diabetic WKY and SHR were randomized into four groups and received distilled water (0.5 mL) and honey (1.0 g/kg) orally once daily for three weeks. Control SHR had reduced malondialdehyde (MDA) and increased systolic blood pressure (SBP), catalase (CAT) activity, and total antioxidant status (TAS). SBP, activities of glutathione peroxidase (GPx) and glutathione reductase (GR) were elevated while TAS was reduced in diabetic WKY. In contrast, SBP, TAS, activities of GPx and GR were reduced in diabetic SHR. Antioxidant (honey) treatment further reduced SBP in diabetic SHR but not in diabetic WKY. It also increased TAS, GSH, reduced glutathione (GSH)/oxidized glutathione (GSSG) ratio, activities of GPx and GR in diabetic SHR. These data suggest that differences in types, severity, and complications of diseases as well as strains may influence responses to blood pressure and oxidative stress. PMID:21673929

    The Attachment and Developmental Dynamic Systems Theory of Crime was tested on 206 male inmates. They completed measures tapping attachments, clinical issues, adverse childhood events, peer crime, and crime addictions. A significant path model was found, going from insecure parental attachments to adverse childhood events, and then on to the behavioral crime addiction and criminal peers scales. Peer crime was also predicted by insecure parent attachments and the crime addiction scale. Finally, the crime addiction, peer crime, and insecure parental attachment scales predicted frequencies of criminal behavior. The model also fit a sample of 239 female inmates. The notions of crime addiction, in this context of adverse events and insecure parental attachments, offered newer and more powerful explanations than previously offered by social learning theories on why some individuals are more likely to associate with peers engaging in criminal behavior, and also how these combine to predict degrees of criminal behavior. By moving beyond main effects models, it was found that a focus on systems of interactions was robust in theory and application. However, profile data from the Attachment and Clinical Issues Questionnaire showed that individual differences in Research Domain Criteria diagnoses are fundamental to treatment settings. Such approaches to reducing rates of recidivism and substance abuse should also enhance outcomes in many domains, including HIV prevention, costs to health care, and at the same time increase overall public safety.

    The sphingosine-1-phosphate (S1P) analog FTY720 exerts pleiotropic effects on the cardiovascular system and causes down-regulation of S1P receptors. Myogenic constriction is an important mechanism regulating resistance vessel function and is known to be modulated by S1P. Here we investigated myogenic constriction and vascular function of mesenteric arteries of rats chronically treated with FTY720. Wistar rats received FTY720 1mg/kg/daily for six weeks. At termination, blood pressure was recorded and small mesenteric arteries collected for vascular studies in a perfusion set up. Myogenic constriction to increased intraluminal pressure was low, but a sub-threshold dose of S1P profoundly augmented myogenic constriction in arteries of both controls and animals chronically treated with FTY720. Interestingly, endothelial denudation blocked the response to S1P in arteries of FTY720-treated animals, but not in control rats. In acute experiments, presence of FTY720 significantly augmented the contractile response to S1P, an effect that was partially abolished after the inhibition of cyclooxygenase (COX-)-derived prostaglandins. FTY720 down regulated S1P1 but not S1P2 in renal resistance arteries and in cultured human endothelial cells. This study therefore demonstrates the endothelium is able to compensate for the complete loss of responsiveness of the smooth muscle layer to S1P after long term FTY720 treatment through a mechanism that most likely involves enhanced production of contractile prostaglandins by the endothelium.

    Experiences of mobile pastoralists often attest to a wide range of contradictions about the presumed advantages of formal education. While effort to 'reach' pastoralists has intensified under the global Education for All movement, there remain considerable difficulties in finding ways to make formal education relate to pastoralist livelihoods and complement endogenous knowledge. This paper examines how these dynamics play out across models of formal and non-formal education service provision, and identifies innovations that offer promising ways forward: Alternative Basic Education, Open and Distance Learning, and Pastoralist Field Schools.

    The appearance and lifelong, chronic nature of psoriasis result in considerable burden to patients, such as sleep impairment, depressive symptoms, negative self-esteem and reduced work productivity. To examine direct and indirect (mediated) effects of secukinumab vs. ustekinumab on quality of life, work productivity and activity impairment based on psoriasis severity and symptoms. Analyses were based on data from the CLEAR study. Structural equation modelling examined the effects of secukinumab vs. ustekinumab on the Dermatology Life Quality Index (DLQI) and on the Work Productivity and Activity Impairment (WPAI) questionnaire using Psoriasis Area and Severity Index (PASI) severity and symptoms (pain, itching and scaling) as potential mediators. Analyses were conducted primarily for patients achieving a PASI 90 response (90% or greater reduction in PASI from baseline) at week 16 (repeated at week 52) and for PASI 50, 75 and 100. Results at weeks 16 and 52 showed that the effect of treatment on change in DLQI score was mediated by the PASI 90 response and by improvements in itching, pain, and scaling. Achieving any PASI response as early as week 16 directly resulted in significantly better WPAI scores. At week 52, both PASI response and improvement in scaling directly resulted in significantly better WPAI scores. Pain, itching and scaling were correlated (r = 0·51-0·68); improvement in any of these had a significant effect (directly or indirectly) on WPAI. All results favoured secukinumab over ustekinumab. The results underscore the important role of both PASI response and reduction in symptoms on improvements in health-related quality of life and work and daily activity in favour of secukinumab vs. ustekinumab. © 2018 British Association of Dermatologists.

  12. Differential effects of topical vitamin E and C E Ferulic® treatments on ultraviolet light B-induced cutaneous tumor development in Skh-1 mice.

    Full Text Available Because of the ever-increasing incidence of ultraviolet light B (UVB-induced skin cancer, considerable attention is being paid to prevention through the use of both sunscreens and after sun treatments, many of which contain antioxidants. Vitamin E is included as an antioxidant in many sunscreens and lotions currently on the market. Studies examining the efficacy of vitamin E as a topical preventative agent for UVB-induced skin cancer have yielded conflicting results. A likely contributor to differences in study outcome is the stability of vitamin E in the particular formulation being tested. In the current study we examined the effects of topical vitamin E alone as well as vitamin E combined with vitamin C and ferulic acid in a more stable topical formula (C E Ferulic®. Mice were exposed to UVB for 10 weeks in order to induce skin damage. Then, before the appearance of any cutaneous lesions, mice were treated for 15 weeks with a topical antioxidant, without any further UVB exposure. We found that topical C E Ferulic decreased tumor number and tumor burden and prevented the development of malignant skin tumors in female mice with chronically UVB-damaged skin. In contrast, female mice chronically exposed to UVB and treated topically with vitamin E alone showed a trend towards increased tumor growth rate and exhibited increased levels of overall DNA damage, cutaneous proliferation, and angiogenesis compared to vehicle-treated mice. Thus, we have demonstrated that topical 5% alpha tocopherol may actually promote carcinogenesis when applied on chronically UVB-damaged skin while treating with a more stable antioxidant compound may offer therapeutic benefits.

    Life threatening complications from chemotherapy occur frequently in cancer survivors, however little is known about genetic risk factors. We treated male normotensive rats (WKY) and strains with hypertension (SHR) and hypertension with cardiomyopathy (SHHF) with 8 weekly doses of doxorubicin (DOX) followed by 12 weeks of observation to test the hypothesis that genetic cardiovascular disease would worsen delayed cardiotoxicity. Compared with WKY, SHR demonstrated weight loss, decreased systolic blood pressure, increased kidney weights, greater cardiac and renal histopathologic lesions and greater mortality. SHHF showed growth restriction, increased kidney weights and renal histopathology but no effect on systolic blood pressure or mortality. SHHF had less severe cardiac lesions than SHR. We evaluated cardiac soluble epoxide hydrolase (sEH) content and arachidonic acid metabolites after acute DOX exposure as potential mediators of genetic risk. Before DOX, SHHF and SHR had significantly greater cardiac sEH and decreased epoxyeicosatrienoic acid (EET) (4 of 4 isomers in SHHF and 2 of 4 isomers in SHR) than WKY. After DOX, sEH was unchanged in all strains, but SHHF and SHR rats increased EETs to a level similar to WKY. Leukotriene D4 increased after treatment in SHR. Genetic predisposition to heart failure superimposed on genetic hypertension failed to generate greater toxicity compared with hypertension alone. The relative resistance of DOX-treated SHHF males to the cardiotoxic effects of DOX in the delayed phase despite progression of genetic disease was unexpected and a key finding. Strain differences in arachidonic acid metabolism may contribute to variation in response to DOX toxicity. - Highlights: • Late doxorubicin toxicity evaluated in normal, hypertensive, and cardiomyopathic rats. • Hypertension enhances the delayed toxicity of doxorubicin. • Genetic predisposition to cardiomyopathy did not further enhance toxicity. • Epoxyeicosatrienoic acids

Post treatment evolution was analysed. 23 Dosimetric studies were performed determining blood and whole body uptake curves (CE)during 5 days. Using the MIRDOSE software, the maximum safe activity in the whole body (CE)was calculated. The retained activity in the body (AR), 48 hs. post tracer dose. Should have been less than 2.96 GBq so as to avoid lung fibrosis. 17 patients that received activities<11.1 GBq, had no side effects. Three patients presents special situations: high AR, users in the mouth, and plaque to and leucopenia. This methodology has benefits because AT can be estimated. This was possible for 85% of the patients. When AR was high at 48 hr, AT was diminished to avoid pulmonary lesions. Tumor absorbed dose estimation, will allow the administration of AT>11.1 GBq in the future. (Author)

    2013-09-01

    We use data collected among Hadza hunter-gatherers between 2005 and 2009 to examine hypotheses about the causes and consequences of men's foraging and food sharing. We find that Hadza men foraged for a range of food types, including fruit, honey, small animals, and large game. Large game were shared not like common goods, but in ways that significantly advantaged producers' households. Food sharing and consumption data show that men channeled the foods they produced to their wives, children, and their consanguineal and affinal kin living in other households. On average, single men brought food to camp on 28% of days, married men without children at home on 31% of days, and married men with children at home on 42% of days. Married men brought fruit, the least widely shared resource, to camp significantly more often than single men. A model of the relationship between hunting success and household food consumption indicates that the best hunters provided 3-4 times the amount of food to their families than median or poor hunters. These new data fill important gaps in our knowledge of the subsistence economy of the Hadza and uphold predictions derived from the household and kin provisioning hypotheses. Key evidence and assumptions backing prior claims that Hadza hunting is largely a form of status competition were not replicated in our study. In light of this, family provisioning is a more viable explanation for why good hunters are preferred as husbands and have higher fertility than others.

    In order to function effectively in post-reform healthcare markets, behavioral healthcare professionals must understand and interact with health purchasing alliances. Healthcare reform initiatives based upon the principles of managed competition envision an important role for cooperative health purchasing organizations, or "health alliances," that collect premiums and contract with health plans for the provision of comprehensive health services delivered within the framework of a standardized benefit package. Health purchasing alliances have already been implemented in eight states, and this trend is expected to grow. The following article illustrates the structure and authority of the health alliances that are already in operation, and is presented here to give Behavioral Healthcare Tomorrow journal readers an up-to-date overview of reforming healthcare markets. This matrix arrays recent state laws which we identify as clearly including components of managed competition or purchasing alliances. Other states undoubtedly have elements of reform that include some aspects of these concepts. For example, under legislation, a Vermont health care authority was established and, among other things, charged with developing two comprehensive reform proposals, one of which will involve multipayors and the other a single-payor system. Options will likely embody many of the activities of alliances. Vermont is not included in this matrix because these provisions are still in the developmental stage.

    Full Text Available A insônia primária é uma dissonia caracterizada pela dificuldade em iniciar e/ou manter o sono e pela sensação de não ter um sono reparador durante um período não inferior a 1 mês. Do ponto de vista polissonográfico, é acompanhada de alterações na indução, na continuidade e na estrutura do sono. Geralmente aparece no adulto jovem, é mais freqüente na mulher e tem um desenvolvimento crônico. A insônia primária é observada de 12,5% a 22,2% dos pacientes portadores de insônia crônica, sendo precedida em freqüência somente na insônia de depressão maior. A insônia primária crônica deve se diferenciar da insônia vinculada a uma higiene inadequada do sono, uma síndrome depressiva ou um transtorno de ansiedade generalizado. O tratamento da insônia primária inclui: higiene adequada do sono, terapia cognitiva e de conduta e uso de fármacos hipnóticos. Entre esses últimos, se destacam o zolpidem e a zopiclona, que melhoram significativamente o sono sem alterar sua estrutura ou induzir a uma reincidência da insônia logo após uma interrupção brusca. Além disso, o desenvolvimento de fármaco-dependência e de vício é muito pouco freqüente.Primary insomnia is a dyssomnia characterized by a complaint of difficulty in initiating or maintaining sleep and the absence of restorative sleep that lasts for at least 1 month. The polysomnographic test shows alterations in the induction, continuity and structure of sleep. Primary insomnia typically begins in young adulthood, has a chronic course, and it is more prevalent among women. Its prevalence among patients with chronic insomnia ranges from 12.5% to 22.2%. Primary insomnia must be distinguished from insomnia related to inadequate sleep hygiene or another mental disorder, such as generalized anxiety disorder or a mood disorder. The treatment of primary insomnia consists of nonpharmacological strategies (sleep hygiene, behavior-cognitive therapy and sleep

    Extracellular signal-regulated kinase 5 (ERK5) is a member of the mitogen-activated protein kinase (MAPK) family and is activated by its upstream kinase, MAPK kinase 5 (MEK5), which is a member of the MEK family. Although the role of MEK5 has been investigated in several fields, little is known about its role in osteoblastic differentiation. In this study, we have demonstrated the role of MEK5 in osteoblastic differentiation in mouse preosteoblastic MC3T3-E1 cells and bone marrow stromal ST2 cells. We found that treatment with BIX02189, an inhibitor of MEK5, increased alkaline phosphatase (ALP) activity and the gene expression of ALP, osteocalcin (OCN) and osterix, as well as it enhanced the calcification of the extracellular matrix. Moreover, osteoblastic cell proliferation decreased at a concentration of greater than 0.5 μM. In addition, knockdown of MEK5 using siRNA induced an increase in ALP activity and in the gene expression of ALP, OCN, and osterix. In contrast, overexpression of wild-type MEK5 decreased ALP activity and attenuated osteoblastic differentiation markers including ALP, OCN and osterix, but promoted cell proliferation. In summary, our results indicated that MEK5 suppressed the osteoblastic differentiation, but promoted osteoblastic cell proliferation. These results implied that MEK5 may play a pivotal role in cell signaling to modulate the differentiation and proliferation of osteoblasts. Thus, inhibition of MEK5 signaling in osteoblasts may be of potential use in the treatment of osteoporosis. - Highlights: • MEK5 inhibitor BIX02189 suppresses proliferation of osteoblasts. • MEK5 knockdown and MEK5 inhibitor promote differentiation of osteoblasts. • MEK5 overexpression inhibits differentiation of osteoblasts.
