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

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

  8. Current Concepts in Adult Acute Rhinosinusitis.

    Science.gov (United States)

    Aring, Ann M; Chan, Miriam M

    2016-07-15

    Acute rhinosinusitis is one of the most common conditions that physicians treat in ambulatory care. Most cases of acute rhinosinusitis are caused by viral upper respiratory infections. A meta-analysis based on individual patient data found that common clinical signs and symptoms were not effective for identifying patients with rhinosinusitis who would benefit from antibiotics. C-reactive protein and erythrocyte sedimentation rate are somewhat useful tests for confirming acute bacterial maxillary sinusitis. Four signs and symptoms that significantly increase the likelihood of a bacterial cause when present are double sickening, purulent rhinorrhea, erythrocyte sedimentation rate greater than 10 mm per hour, and purulent secretion in the nasal cavity. Although cutoffs vary depending on the guideline, antibiotic therapy should be considered when rhinosinusitis symptoms fail to improve within seven to 10 days or if they worsen at any time. First-line antibiotics include amoxicillin with or without clavulanate. Current guidelines support watchful waiting within the first seven to 10 days after upper respiratory symptoms first appear. Evidence on the use of analgesics, intranasal corticosteroids, and saline nasal irrigation for the treatment of acute rhinosinusitis is poor. Nonetheless, these therapies may be used to treat symptoms within the first 10 days of upper respiratory infection. Radiography is not recommended in the evaluation of uncomplicated acute rhinosinusitis. For patients who do not respond to treatment, computed tomography of the sinuses without contrast media is helpful to evaluate for possible complications or anatomic abnormalities. Referral to an otolaryngologist is indicated when symptoms persist after maximal medical therapy and if any rare complications are suspected.

    In this study the ten factors which compose the Ricketts' summary analysis were measured on 81 lateral skull radiographs of adult Greeks (41 males and 40 females) with normal occlusion and harmonious face to establish cephalometric standards. The mean value, standard deviation, standard error of the mean, minimum and maximum values as well as the range of each variable were found and discussed for each sex separately as well as for the whole sample. The main conclusion of the study is that adult Greeks with normal occlusion and harmonious face present: a tendency to the brachy facial vertical type, a small retroposition of the maxilla and of the lower lip and prominent and labialy proclined lower incisors.

    Full Text Available Objectives. To compare prevalence estimates and assess issues related to the measurement of adult cigarette smoking in the National Health Interview Survey (NHIS and the National Survey on Drug Use and Health (NSDUH. Methods. 2008 data on current cigarette smoking and current daily cigarette smoking among adults ≥18 years were compared. The standard NHIS current smoking definition, which screens for lifetime smoking ≥100 cigarettes, was used. For NSDUH, both the standard current smoking definition, which does not screen, and a modified definition applying the NHIS current smoking definition (i.e., with screen were used. Results. NSDUH consistently yielded higher current cigarette smoking estimates than NHIS and lower daily smoking estimates. However, with use of the modified NSDUH current smoking definition, a notable number of subpopulation estimates became comparable between surveys. Younger adults and racial/ethnic minorities were most impacted by the lifetime smoking screen, with Hispanics being the most sensitive to differences in smoking variable definitions among all subgroups. Conclusions. Differences in current cigarette smoking definitions appear to have a greater impact on smoking estimates in some sub-populations than others. Survey mode differences may also limit intersurvey comparisons and trend analyses. Investigators are cautioned to use data most appropriate for their specific research questions.

    Full Text Available Objective : To develop a consensus for translation of the most relevant terms used in the study of Adult Spinal Deformity, from their original languages into Brazilian Portuguese. Methods : A panel of 12 experts in spine surgery from the five Brazilian regions was constituted. To obtain the standardization of terminology, the Delphi method with an electronic questionnaire was administered to participants about their opinion on the translation of 13 relevant terms chosen by literature review. Each term was considered standard when there was consensus, that is, concordance higher than 80% among participants as to the suggestion to be adopted, and then on the acceptance of the term and its abbreviation in Portuguese. Results : Initially there was consensus (over 80% concordance on the translation of seven terms in the electronic questionnaire. The other six terms that have not reached consensus were discussed at a meeting among the participants, relying on the opinion of a specialized professional in simultaneous translation of orthopedic terms in Portuguese and other professional majored in Portuguese language. It was decided how these terms should be translated and there was a consensus among all participants regarding their acceptance. Finally, there was consensus among the participants, who agreed with the translation and abbreviation of the 13 propose terms, defining its standardization for Brazilian Portuguese. Conclusion : We present a standard terminology used in the study of Adult Spinal Deformity through consensus among experts, seeking uniformity in the use of these terms in Brazilian Portuguese.

  12. Standards for scalable clinical decision support: need, current and emerging standards, gaps, and proposal for progress.

    2010-01-01

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

  14. Current safety standards in infant nutrition--a European perspective.

    Science.gov (United States)

    Hernell, Olle

    2012-01-01

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

    Garvin, Heather M; Passalacqua, Nicholas V

    2012-03-01

    When determining an age estimate from adult skeletal remains, forensic anthropologists face a series of methodological choices. These decisions, such as which skeletal region to evaluate, which methods to apply, what statistical information to use, and how to combine information from multiple methods, ultimately impacts the final reported age estimate. In this study, a questionnaire was administered to 145 forensic anthropologists, documenting current trends in adult age at death estimation procedures used throughout the field. Results indicate that the Suchey-Brooks pubic symphysis method (1990) remains the most highly favored aging technique, with cranial sutures and dental wear being the least preferred, regardless of experience. The majority of respondents stated that they vary their skeletal age estimate process case-by-case and ultimately present to officials both a narrow and broad possible age range. Overall, respondents displayed a very high degree of variation in how they generate their age estimates, and indicated that experience and expertise play a large role in skeletal age estimates.

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

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

    Weight management encompasses the inter-relationship of nutrition, physical activity, and health behavior change. Nutrition is key for the prevention and treatment of obesity and chronic disease and maintenance of overall health. Thus, the Weight Management Dietetic Practice Group, with guidance from the Academy of Nutrition and Dietetics Quality Management Committee, has developed Standards of Practice and Standards of Professional Performance for Registered Dietitian Nutritionists (RDNs) in Adult Weight Management as a resource for RDNs working in weight management. This document allows RDNs to assess their current skill levels and to identify areas for further professional development in this expanding practice area. This document describes the current standards for weight management practice for RDNs. The Standards of Practice represent the four steps in the Nutrition Care Process as applied to the care of patients/clients. The Standards of Professional Performance consist of six domains of professionalism: Quality in Practice, Competence and Accountability, Provision of Services, Application of Research, Communication and Application of Knowledge, and Utilization and Management of Resources. Within each standard, specific indicators provide measurable action statements that illustrate how the standard can be applied to practice. The indicators describe three skill levels (competent, proficient, and expert) for RDNs working in weight management. The Standards of Practice and Standards of Professional Performance are complementary resources for the Registered Dietitian Nutritionist in weight management.

    2008-07-01

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

    2005-06-01

    Although attachment theory suggests that childhood experiences with caregivers serve as a prototype for adult love relationships, few explicit tests of this hypothesis exist in the literature. Drawing on data from a longitudinal cohort followed from birth to young adulthood, this paper examined correlates and antecedents of young adults' representations of and behavior in their current romantic relationship. Young adults who experienced a secure relationship with their primary caregiver in infancy as assessed in the Strange Situation were more likely to (a) produce coherent discourse regarding their current romantic partnership in the context of the Current Relationship Interview (CRI) and (b) have a higher quality romantic relationship as observed in standard conflict and collaboration tasks. Infant security accounted for variation in CRI security above and beyond the observed quality of participants' current romantic relationship. In contrast, the association between infant and romantic security was partially mediated by individuals' self-reports about their romantic experiences, suggesting that one plausible mechanism by which early experiences with caregivers shape young adults' representations of their attachments with romantic partners is through adults' expectations for and perceptions of love relationships.

    Tobacco use is the leading cause of preventable disease and death in the United States, and cigarettes are the most commonly used tobacco product among U.S. adults (1,2). To assess progress toward achieving the Healthy People 2020 target of reducing the proportion of U.S. adults who smoke cigarettes to ≤12.0% (objective TU1.1),* CDC assessed the most recent national estimates of cigarette smoking prevalence among adults aged ≥18 years using data from the 2015 National Health Interview Survey (NHIS). The proportion of U.S. adults who smoke cigarettes declined from 20.9% in 2005 to 15.1% in 2015, and the proportion of daily smokers declined from 16.9% to 11.4%. However, disparities in cigarette smoking persist. In 2015, prevalence of cigarette smoking was higher among adults who were male; were aged 25-44 years; were American Indian/Alaska Native; had a General Education Development certificate (GED); lived below the federal poverty level; lived in the Midwest; were insured through Medicaid or were uninsured; had a disability/limitation; were lesbian, gay, or bisexual; or who had serious psychological distress. Proven population-based interventions, including tobacco price increases, comprehensive smoke-free laws, anti-tobacco mass media campaigns, and barrier-free access to tobacco cessation counseling and medications, are critical to reducing cigarette smoking and smoking-related disease and death among U.S. adults, particularly among subpopulations with the highest smoking prevalences (3).

    2015-11-01

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

    Richesson, Rachel L; Nadkarni, Prakash

    2011-05-01

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

  14. 3D standard brain of the red flour beetle Tribolium castaneum: a tool to study metamorphic development and adult plasticity

    2010-03-01

    Full Text Available The red flour beetle Tribolium castaneum is emerging as a further standard insect model beside Drosophila. Its genome is fully sequenced and it is susceptible for genetic manipulations including RNA-interference. We use this beetle to study adult brain development and plasticity primarily with respect to the olfactory system. In the current study, we provide 3D standard brain atlases of freshly eclosed adult female and male beetles (A0. The atlases include eight paired and three unpaired neuropils including antennal lobes, optic lobe neuropils, mushroom body calyces and pedunculi, and central complex. For each of the two standard brains, we averaged brain areas of 20 individual brains. Additionally, we characterized eight selected olfactory glomeruli from 10 A0 female and male beetles respectively, which we could unequivocally recognize from individual to individual owing to their size and typical position in the antennal lobes. In summary, comparison of the averaged neuropil volumes revealed no sexual dimorphism in any of the reconstructed neuropils in A0 Tribolium brains. Both, the female and male 3D standard brain are also used for interspecies comparisons, and, very importantly, will serve as future volumetric references after genetical manipulation especially regarding metamorphic development and adult plasticity.

    Freer, Matt; Webster, Chris; Freundinger, Larry

    2016-06-01

    Commission I of the International Society for Photogrammetric and Remote Sensing formed working group I/1 for the purpose of standardizing airborne platform interfaces. The primary mission of this working group is to promote the standardization of instrument interfaces, data formats, and supporting infrastructures; and to facilitate more efficient, flexible, and cost-effective international science flight operations. Within WGI/1 are a number of focused subgroups. This paper addresses the efforts of some of these subgroups having interdependent and overlapping interests; including the development of standard software interfaces for sensors, standardized approaches to management of information over potentially intermittent wireless data links, the development of standardized processing algorithms, and data archival format standards. The data in this report reflect the outcome of work-to-date in the current subgroups.

  20. Adult Sexual Experiences as a Mediator Between Child Abuse and Current Secretory Immunoglobulin A Levels.

    Waldron, Jonathan C; Scarpa, Angela; Kim-Spoon, Jungmeen; Coe, Christopher L

    2016-03-01

    The current study investigated whether a history of child abuse is a predictor of adult immune status, with unwanted adult sexual experiences as a proximal mediator. Participants included 89 young adult women (M(age) = 19.24) who were classified as having experienced no child abuse, child physical abuse, or child sexual abuse, based upon self-reported victimization history before 14 years of age. Participants also reported on unwanted sexual experiences in young adulthood and provided four saliva samples, which were collected over two consecutive days to determine secretory immunoglobulin A (sIgA). Age and negative life events were considered as covariates. The results indicated that adult sexual victimization partially mediated the relationship between child abuse (physical and sexual) and sIgA. Specifically, child abuse experiences predicted more adult sexual victimization experiences, which in turn predicted lower sIgA levels. These findings support long-term health effects of victimization, and suggest that the influence of child abuse on sIgA may be perpetuated through adult victimization. Prevention efforts should aim to empower child maltreatment survivors with skills to prevent adult re-victimization. By thwarting future unwanted sexual experiences in adulthood, individuals will be better protected from the health impairments associated with early abuse experiences.

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

  2. Adult social attachment disturbance is related to childhood maltreatment and current symptoms in borderline personality disorder.

    Minzenberg, Michael J; Poole, John H; Vinogradov, Sophia

    2006-05-01

    We characterized borderline personality disorder (BPD) along two fundamental dimensions of adult social attachment and evaluated attachment associations with childhood maltreatment and current symptoms using self-report measures in 40 outpatients with DSM-IV BPD. The BPD group had significantly greater dimensional attachment impairment and rate of fearful attachment type compared with a healthy control group. Among BPD subjects, dimensional attachment-anxiety was specifically associated with sexual abuse, whereas attachment-avoidance was associated with all five maltreatment types. The two attachment dimensions showed divergent associations with current interpersonal problems, impulsivity subtypes and mood symptoms. We conclude that (1) BPD is characterized by adult attachment disturbance; (2) these attachment problems are strongly related to childhood maltreatment, and to current interpersonal problems and clinical symptoms that are considered core features of BPD; and (3) the diverse problems of BPD patients may arise from two basic mechanisms, each tied to a different type of attachment disturbance, developmental history, and clinical outcome.

    Direct current electrical fields have been shown to be a major factor in the regulation of cell proliferation, differentiation, migration, and survival, as well as in the maturation of dividing cells during development. During adulthood, spinal cord cells are continuously produced in both animals and humans, and they hold great potential for neural restoration following spinal cord injury. While the effects of direct current electrical fields on adult-born spinal cells cultured ex vivo have recently been reported, the effects of direct current electrical fields on adult-born spinal cells in vivo have not been characterized. Here, we provide convincing findings that a therapeutic form of transspinal direct current stimulation (tsDCS) affects the migration and proliferation of adult-born spinal cells in mice. Specifically, cathodal tsDCS attracted the adult-born spinal cells, while anodal tsDCS repulsed them. In addition, both tsDCS polarities caused a significant increase in cell number. Regarding the potential mechanisms involved, both cathodal and anodal tsDCS caused significant increases in expression of brain-derived neurotrophic factor, while expression of nerve growth factor increased and decreased, respectively. In the spinal cord, both anodal and cathodal tsDCS increased blood flow. Since blood flow and angiogenesis are associated with the proliferation of neural stem cells, increased blood flow may represent a major factor in the modulation of newly born spinal cells by tsDCS. Consequently, we propose that the method and novel findings presented in the current study have the potential to facilitate cellular, molecular, and/or bioengineering strategies to repair injured spinal cords.NEW & NOTEWORTHY Our results indicate that transspinal direct current stimulation (tsDCS) affects the migratory pattern and proliferation of adult newly born spinal cells, a cell population which has been implicated in learning and memory. In addition, our results suggest a

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

  5. Electric current in flares ribbons: from the standard model in 3D to observations

    2014-01-01

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

  6. Training in clinical forensic medicine in the UK--perceptions of current regulatory standards.

    Stark, Margaret M; Norfolk, Guy A

    2011-08-01

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

    Older adults frequently experience a decrease in balance control that leads to increased numbers of falls, injuries and hospitalization. Therefore, evaluating older adults’ ability to maintain balance and examining new approaches to counteract age-related decline in balance control is of great importance for fall prevention and healthy aging.

    Full Text Available Voltage-gated calcium currents and potassium currents were shown to undergo developmental changes in postnatal human and animal cardiomocytes. However, so far, there is no evidence whether sodium currents also presented the developmental changes in postnatal human atrial cells. The aim of this study was to observe age-related changes of sodium currents between pediatric and adult atrial myocytes. Human atrial myocytes were acutely isolated and the whole-cell patch clamp technique was used to record sodium currents isolated from pediatric and adult atrial cardiomocytes. The peak amplitude of sodium currents recorded in adult atrial cells was significantly larger than that in pediatric atrial myocytes. However, there was no significant difference of the activation voltage for peak sodium currents between two kinds of atrial myocytes. The time constants for the activation and inactivation of sodium currents were smaller in adult atria than pediatric atria. The further study revealed that the voltage-dependent inactivation of sodium currents were more slow in adult atrial cardiomyocytes than pediatric atrial cells. A significant difference was also observed in the recovery process of sodium channel from inactivation. In summary, a few significant differences were demonstrated in sodium currents characteristics between pediatric and adult atrial myocytes, which indicates that sodium currents in human atria also undergo developmental changes.

    Full Text Available Determination of an optimal Laryngeal Mask Airway (LMA insertion technique is of great importance as unsuccessful prolonged insertion and multiple attempts are associated with adverse respiratory effects and trauma. The purpose of this study was to compare the ease of insertion of LMA using the standard approach with lateral and rotational techniques. 150 adult patients undergoing general anesthesia using LMA were randomized into one of the three mentioned techniques: standard, rotational and lateral. The time for LMA insertion, number of LMA insertion attempts and LMA insertion success rate were noted for all patients. Demographic characteristic of patients between three groups did not have significant difference. Patients irritation and time for LMA insertion was significantly less in lateral technique (P

    Full Text Available This study explored a longitudinal data set of 6875 British adults examining the effects of parental social status (measured at birth, cognitive ability (at age 11 yrs, personality traits, education and occupational attainment on physical health and functioning (all measured at age 50 yrs, after taking account of current health conditions (number of illness. Correlation analysis showed that parental social class, childhood cognitive ability, education and occupation, and two personality traits (Emotional Stability/Neuroticism, and Conscientiousness were all significantly associated with adult physical health variables. Structural equation modelling showed that health conditions and personality traits were significantly, and inversely, associated with physical health (indicated by good daily physical functioning, relative absence of pain, perceived health, and low level of limitations at work due to physical health. Parental social status, childhood intelligence, educational and occupational attainment were all modestly, but significantly and directly, associated with adult physical health. The effect of childhood intelligence on adult physical health was, in part, mediated through Emotional Stability and Conscientiousness. After controlling for health conditions Emotional Stability was the strongest predictor of physical health. Implications and limitations are discussed.

    2001-09-01

    Although John Bowlby conceptualized attachment theory as applicable across the life span, researchers have been relatively slow to examine attachment phenomena specifically among older adults. The present article reviews the extant research applying attachment theory to older populations; preliminary findings suggest that attachment issues hold particular relevance for older adults, given the increased potential for separation, loss and vulnerability associated with aging. Although many of the studies reviewed are somewhat limited methodologically, the overall pattern of results suggests that attachment patterns are associated with a variety of outcomes in later life (such as adaptation to chronic illness and caregiver burden among family members, reactions to the death of a loved one, and general well-being) in a theoretically consistent manner. The implications of and questions raised by current findings are reviewed, and directions for future research are discussed.

  14. Multimodal Study of Adult-Infant Interaction: A Review of Its Origins and Its Current Status

    Soledad Carretero Pérez

    Full Text Available Abstract An interpretative review of research on adult-infant interactions involving the analysis of movement behaviors is presented, systematically linking previous studies to current research on the subject. Forty-two articles analyzing the dyad's interactive movement in the period 1970-2015 were found. Twelve papers were excluded, including only those that studied the phenomenon in the baby's first year of life. The results revealed that movement was a central topic in early interaction studies in the 70s. In the 1980's and 1990's, its study was marginal and it is currently resurging under the embodiment perspective. The conceptual framework and research methods used in the pioneering work are presented, and the thematic foci shared with current research are highlighted. Thus, essential keys are provided for the updated study of early interactions from a multimodal perspective.

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

    Sheldon, R. B.; Hamilton, D. C.

    1993-01-01

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

  18. Including Alternative Resources in State Renewable Portfolio Standards: Current Design and Implementation Experience

    Energy Technology Data Exchange (ETDEWEB)

    Heeter, J.; Bird, L.

    2012-11-01

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

    2012-09-01

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

    Persistent tetrodotoxin-sensitive sodium current (INaP) plays an important role in cellular and neuronal network excitability in physiological conditions and under different pathological circumstances. However, developmental changes in INaP properties remain largely unclear. In the present study using whole cell patch clamp technique we evaluated INaP properties in CA1 hippocampal pyramidal neurons isolated from young (postnatal day (P) 12-16) and adult (P60-75) rats. We show that the INaP density is substantially larger in the adult group. Although INaP inactivation characteristics were found to be similar in both groups, voltage dependence of INaP activation is shifted to more negative membrane potentials (young: -48.6±0.5mV vs. adult: -52.4±0.2mV, p<0.01). Our data indicates the increase of INaP contribution in the basal membrane sodium conductivity in the mature hippocampus.

    To better understand the contribution of the dorsal system to word reading, we explored transcranial direct current stimulation (tDCS) effects when adults with developmental dyslexia received active stimulation over the visual extrastriate area MT/V5, which is dominated by magnocellular input. Stimulation was administered in 5 sessions spread over two weeks, and reading speed and accuracy as well as reading fluency were assessed before, immediately after, and a week after the end of the treatment. A control group of adults with developmental dyslexia matched for age, gender, reading level, vocabulary and block-design WAIS-III sub-tests and reading level was exposed to the same protocol but with sham stimulation. The results revealed that active, but not sham stimulation, significantly improved reading speed and fluency. This finding suggests that the dorsal stream may play a role in efficient retrieval from the orthographic input lexicon in the lexical route. It also underscores the potential of tDCS as an intervention tool for improving reading speed, at least in adults with developmental dyslexia.

    In Latin America, adult influenza is a serious disease that exacts a heavy burden in terms of morbidity, mortality, and cost. Although much has been written about the disease itself, relatively little information has been compiled on what could be done to reduce its impact across the region, particularly from the perspective of clinicians with first-hand experience in confronting its effects. To fill this data gap, in 2011, the Pan American Health and Education Foundation (PAHEF) and the U.S.-based nonprofit Fighting Infectious Diseases in Emerging Countries (FIDEC) organized a conference and convened a panel of Latin American scientist-clinicians with experience and expertise in adult influenza in the region tol) discuss the major issues related to the disease and 2) develop and produce a consensus statement summarizing its impact as well as current efforts to diagnose, prevent, and treat it. The consensus panel concluded a more concerted and better-coordinated effort was needed to reduce the adverse impact of seasonal influenza and future pandemics, including more surveillance, more active involvement by both governmental and nongovernmental organizations, and a much greater effort to vaccinate more adults, especially those at high risk of contracting the disease. In addition, a new approach for diagnosing influenza was recommended.

    2013-09-01

    Disposable absorbent products are widely used in inpatient care settings and in the community to manage adult urinary and fecal incontinence, but few product standards exist to help guide their production or optimal use. Increasing costs and reduced revenues have caused a number of states to evaluate absorbent product use among persons who receive care at home with the assistance of the Medicaid Waiver Program, further increasing concerns about the lack of product performance standards. To address these issues, the National Association For Continence (NAFC) formed a council of experts and key stakeholders with the objective of establishing national, independent quality performance standards for disposable absorbent products provided by states to Waiver Program recipients. The Council consisted of representatives from five purposefully selected states, technical directors from six nonwoven product manufacturers, an officer of the nonwoven manufactures trade association, a delegate from an academic nursing program and professional societies, a family caregiver, and a patient representative. Following a consensus method and guidelines for use, nine specific recommendations were developed, posted for public comment, and further refined. Final recommendations for product performance assessment include: rewet rate (a measure of a product's ability to withstand multiple incontinent episodes between changes), rate of acquisition (a measure of the speed at which urine is drawn away from the skin by a product, product retention capacity (a measure of a product's capacity to hold fluid without rewetting the skin), sizing options, absorbency levels, product safety, closure technology, breathable zones (a measure of the air permeability across a textile-like fabric at a controlled differential pressure), and elasticity. The Council also set values for and recommended four quantifiable parameters, and the testing methodology associated with each, to help consumers and states

    Cognitive impairment is nearly ubiquitous in schizophrenia. First-degree relatives of persons with schizophrenia often show similar but milder deficits. Current methods for the treatment of schizophrenia are often ineffective in cognitive remediation. Since transcranial direct current stimulation (tDCS) can enhance cognitive functioning in healthy adults, it might provide a viable option to enhance cognition in schizophrenia. We sought to explore whether tDCS can be tolerated by persons with schizophrenia and potentially improve their cognitive functioning. We examined the effects of anodal versus cathodal tDCS on working memory and other cognitive tasks in five outpatients with schizophrenia and six first-degree relatives of persons with schizophrenia. Each participant completed tasks thought to be mediated by the prefrontal cortex during two 30-minute sessions of tDCS to the left and right dorsolateral prefrontal cortex (DLPFC). Anodal stimulation over the left DLPFC improved performance relative to cathodal stimulation on measures of working memory and aspects of verbal fluency relevant to word retrieval. The patient group showed differential changes in novel design production without alteration of overall productivity, suggesting that tDCS might be capable of altering selfmonitoring and executive control. All participants tolerated tDCS well. None withdrew from the study or experienced any adverse reaction. We conclude that adults with schizophrenia can tolerate tDCS while engaging in cognitive tasks and that tDCS can alter their performance.

    Full Text Available Due to their low self-repair ability, cartilage defects that result from joint injury, aging, or osteoarthritis, are the most often irreversible and are a major cause of joint pain and chronic disability. So, in recent years, researchers and surgeons have been working hard to elaborate cartilage repair interventions for patients who suffer from cartilage damage. However, current methods do not perfectly restore hyaline cartilage and may lead to the apparition of fibro- or hypertrophic cartilage. In the next years, the development of new strategies using adult stem cells, in scaffolds, with supplementation of culture medium and/or culture in low oxygen tension should improve the quality of neoformed cartilage. Through these solutions, some of the latest technologies start to bring very promising results in repairing cartilage from traumatic injury or chondropathies. This review discusses the current knowledge about the use of adult stem cells in the context of cartilage tissue engineering and presents clinical trials in progress, as well as in the future, especially in the field of bioprinting stem cells.

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

    Full Text Available Hope is one of important factors affecting the psychological state of individuals. It influences well-being and self-esteem, academic and athletic performance, and even the probability of repeated incarceration of offenders. It also predicts the efficacy of the systematic psychotherapy of mental disorders, as well as the supportive psychotherapy in patients with oncologic illnesses. Hope has a central position in positive and clinical psychology. The aim of the presented work was to translate the adult dispositional hope scale into Czech, verify its psychometric properties and develop the norms for interpreting the resulting scores. The scale could be helpful both in mental health research and practice. 394 healthy adults participated in the study. The average age of the probands was 27.1 + 11.7 years. There were more women (n = 303; i.e. 76.9 % than men. The most common level of education was secondary (n = 309; 78.4 %. The participants were mainly students (n = 273; 69.3 % or employees and self-employed individuals (n = 113; 28.7 %. Most of them were single (n = 300; 76.1 % or married (n = 84; 21.3 %. The Adult Dispositional Hope Scale consists of 12 items. Four items measure pathways thinking (i.e. the ability to find ways to achieve one's goals and four items assess agency (i.e. goal-directed energy. The remaining four items are fillers that are not interpreted. Apart from this scale, all participants completed a demographic questionnaire and the second version of the Beck Depression Inventory. The statistical analyses consisted of the Cronbach's alpha and Spearman-Brown coefficient analysis, the exploratory and confirmatory factor analysis, the correlation between the standardized scale and the Beck Depression Inventory-II, and finally the creation of the norms based on the stens. The overall rate of hope was not statistically significantly associated with the subjects' age (Spearman r = -0.06, non-significant, nor with their sex (Mann

    Older adults frequently experience a decrease in balance control that leads to increased numbers of falls, injuries and hospitalization. Therefore, evaluating older adults' ability to maintain balance and examining new approaches to counteract age-related decline in balance control is of great importance for fall prevention and healthy aging. Non-invasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) have been shown to beneficially influence motor behavior and motor learning. In the present study, we investigated the influence of tDCS applied over the leg area of the primary motor cortex (M1) on balance task learning of healthy elderly in a dynamic balance task (DBT). In total, 30 older adults were enrolled in a cross-sectional, randomized design including two consecutive DBT training sessions. Only during the first DBT session, either 20 min of anodal tDCS (a-tDCS) or sham tDCS (s-tDCS) were applied and learning improvement was compared between the two groups. Our data showed that both groups successfully learned to perform the DBT on both training sessions. Interestingly, between-group analyses revealed no difference between the a-tDCS and the s-tDCS group regarding their level of task learning. These results indicate that the concurrent application of tDCS over M1 leg area did not elicit DBT learning enhancement in our study cohort. However, a regression analysis revealed that DBT performance can be predicted by the kinematic profile of the movement, a finding that may provide new insights for individualized approaches of treating balance and gait disorders.

    Suicide is a leading cause of death among young adults and the rate of suicide has been increasing for decades. A depression distress amplification model posits that young adults with comorbid depression and anxiety have elevated suicide rates due to the intensification of their depressive symptoms by anxiety sensitivity cognitive concerns. The current study tested the effects of anxiety sensitivity subfactors as well as the depression distress amplification model in a very large sample of college students with elevated suicide risk. Participants were 721 college students who were at elevated risk of suicidality (scored>0 on the Beck Scale for Suicide Ideation). Consistent with prior work, anxiety sensitivity cognitive concerns, but not physical or social concerns, were associated with suicidal ideation. Consistent with the depression distress amplification model, in individuals high in depression, anxiety sensitivity cognitive concerns predicted elevated suicidal ideation but not among those with low depression. The results of this study corroborate the role of anxiety sensitivity cognitive concerns and the depression distress amplification model in suicidal ideation among a large potentially high-risk group of college students. The depression distress amplification model suggests a specific mechanism, anxiety sensitivity cognitive concerns, that may be responsible for increased suicide rates among those with comorbid anxiety and depression.

    Full Text Available Recently, transcranial alternating current stimulation (tACS has emerged as a tool to enhance human cognitive processes. Here, we provide a brief summary of the rationale behind tACS-induced effects on task-relevant brain oscillations and associated cognitive functions and review previous studies in young subjects that have applied tACS in cognitive paradigms. Additionally, we present pilot data where we administered theta-tACS (6 Hz over the temporoparietal cortex and a supraorbital reference for 20 min during implicit language learning in healthy young (mean/SD age: 22/2 and older (mean/SD age: 66/4 adults, in a sham-controlled crossover design. Linear mixed models revealed significantly increased retrieval accuracy following tACS-accompanied associative learning, after controlling for session order and learning success. These data provide the first implementation of tACS during cognitive performance in older adults and support recent studies suggesting that tACS in the theta frequency range may serve as a tool to enhance cognition, possibly through direct modulation of task-relevant brain oscillations. So far, studies have been heterogeneous in their designs, leaving a number of issues to be addressed in future research, including the setup of electrodes and optimal stimulation frequencies to be employed, as well as the interaction with age and underlying brain pathologies in specific patient populations.

    With European demographic developments causing a decline of the available workforce in the foreseeable future and the unsustainability of dominant pay-as-you-go pension systems (where contributions from the current workforce sustain pensioners), governments need to come up with strategies to deal with this upcoming challenge and to adjust their policies. Based on a study carried out between September 2009 and May 2010, this article evaluates the policies guiding late-life education in Malta, as well as the local plethora of learning opportunities for older adult education, and participation rates. The Maltese government is committed to supporting the inclusion of older persons (aged 60+) in lifelong education policies and programmes, to the extent that local studies have uncovered a recent rise in the overall participation of older adults in formal, non-formal and informal areas of learning. While the present and future prospects for late-life education in Malta seem promising, a critical scrutiny of present ideologies and trends finds the field to be no more than seductive rhetoric. Though the coordination of late-life education in Malta does result in various social benefits to older learners and Maltese society in general, it also occurs within five intersecting lines of inequality - namely an economic rationale, elitism, gender bias, the urban-rural divide and third ageism. This article ends by proposing policy recommendations for the future of late-life education.

    Concomitant to the increased use of dental implants to replace lost dentition, there is a growing need to regenerate atrophic jaw bone to allow dental implant placement. Current surgical techniques for jaw bone augmentation share several limitations, such as operator sensitivity and relatively low predictability and high morbidity rates. Therefore, alternative treatment approaches have been developed in the field of tissue engineering. Bone tissue engineering integrates the use of different scaffolds, growth factors, and stem cells. This method aims to induce bone augmentation of large bone defects by mimicking biologic processes that occur during embryogenesis. This review will present available sources for adult stem cells, the rationale for using stem cells for bone regeneration, and recent studies that use mesenchymal stem cells (MSC) and endothelial progenitor cells (EPC) to induce bone augmentation.

    2003-06-01

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

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

    In computed tomography (CT), patient-specific organ dose can be estimated using pre-calculated organ dose conversion coefficients (organ dose normalized by CTDIvol, h factor) database, taking into account patient size and scan coverage. The conversion coefficients have been previously estimated for routine body protocol classes, grouped by scan coverage, across an adult population for fixed tube current modulated CT. The coefficients, however, do not include the widely utilized tube current (mA) modulation scheme, which significantly impacts organ dose. This study aims to extend the h factors and the corresponding dose length product (DLP) to create effective dose conversion coefficients (k factor) database incorporating various tube current modulation strengths. Fifty-eight extended cardiac-torso (XCAT) phantoms were included in this study representing population anatomy variation in clinical practice. Four mA profiles, representing weak to strong mA dependency on body attenuation, were generated for each phantom and protocol class. A validated Monte Carlo program was used to simulate the organ dose. The organ dose and effective dose was further normalized by CTDIvol and DLP to derive the h factors and k factors, respectively. The h factors and k factors were summarized in an exponential regression model as a function of body size. Such a population-based mathematical model can provide a comprehensive organ dose estimation given body size and CTDIvol. The model was integrated into an iPhone app XCATdose version 2, enhancing the 1st version based upon fixed tube current modulation. With the organ dose calculator, physicists, physicians, and patients can conveniently estimate organ dose.

    Chronic rhinosinusitis (CRS) affects more than 10% of the population in the United States and Europe. Recent findings point to a considerable variation of inflammatory subtypes in patients with CRS with nasal polyps and patients with CRS without nasal polyps. According to current guidelines, glucocorticosteroids and antibiotics are the principle pharmacotherapeutic approaches; however, they fail in a group of patients who share common clinical and laboratory markers. Several clinical phenotypes often leading to uncontrolled disease, including adult nasal polyposis, aspirin-exacerbated respiratory disease, and allergic fungal rhinosinusitis, are characterized by a common endotype: a TH2 bias is associated with a higher likelihood of comorbid asthma and recurrence after surgical treatment. As a consequence, several innovative approaches targeting the TH2 bias with humanized mAbs have been subjected to proof-of-concept studies in patients with CRS with nasal polyps with or without comorbid asthma: omalizumab, reslizumab, mepolizumab, and recently dupilumab. Future concepts using upstream targets, such as GATA-3, also focus on this endotype. This current development might result in advantages in the treatment of patients with the most severe CRS.

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

    CERN Document Server

    Kroupa, Pavel

    2012-01-01

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

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

    Full Text Available Language facilitation by transcranial direct current stimulation (tDCS in healthy individuals has generated hope that tDCS may also allow improving language impairment after stroke (aphasia. However, current stimulation protocols have yielded variable results and may require identification of residual language cortex using functional magnetic resonance imaging (fMRI, which complicates incorporation into clinical practice. Based on previous behavioral studies that demonstrated improved language processing by motor system pre-activation, the present study assessed whether tDCS administered to the primary motor cortex (M1 can enhance language functions.This proof-of-concept study employed a sham-tDCS controlled, cross-over, within-subject design and assessed the impact of unilateral excitatory (anodal and bihemispheric (dual tDCS in eighteen healthy older adults during semantic word-retrieval and motor speech tasks. Simultaneous fMRI scrutinized the neural mechanisms underlying tDCS effects.Both active tDCS conditions significantly improved word-retrieval compared to sham-tDCS. The direct comparison of activity elicited by word-retrieval vs. motor-speech trials revealed bilateral frontal activity increases during both anodal- and dual-tDCS compared to sham-tDCS. This effect was driven by more pronounced deactivation of frontal regions during the motor-speech task, while activity during word-retrieval trials was unaffected by the stimulation. No effects were found in M1 and secondary motor regions.Our results show that tDCS administered to M1 can improve word-retrieval in healthy individuals, thereby providing a rationale to explore whether M1-tDCS may offer a novel approach to improve language functions in aphasia. fMRI revealed neural facilitation specifically during motor speech trials, which may have reduced switching costs between the overlapping neural systems for lexical retrieval and speech processing, thereby resulting in improved

    Although several studies have reported that child physical abuse increased the risk for bullying involvement, the effect of current violence from adult family members (CVA) on bullying involvement and suicidal feelings among adolescents has not been sufficiently examined. This study investigated the association of CVA with adolescent bullying involvement and the interaction effect of CVA and bullying involvement on suicidal feelings. This cross-sectional study used data from a school-based survey with a general population of adolescents (grades 7 to 12). Data were collected using a self-report questionnaire completed by 17,530 students. Logistic regression analyses were performed to explore the association of CVA with adolescent bullying involvement and suicidal feelings. The overall response rate was 90.2%. The odds of students being characterized as bullies, victims, and bully-victims were higher among adolescents with CVA than without CVA (odds ratios (OR) = 2.9, 95% confidence interval (CI), [2.3–3.7], 4.6 [3.6–5.8], and 5.8 [4.4–7.6], respectively). Both CVA (OR = 3.4 [95% CI 2.7–4.3]) and bullying (bullies, victims, and bully-victims; OR = 2.0 [95% CI 1.6–2.6], 4.0 [3.1–5.1], 4.1 [3.0–5.6], respectively), were associated with increased odds of current suicidal feelings after adjusting for confounding factors. Furthermore, positive additive effects of CVA and all three types of bullying involvement on suicidal feelings were found. For example, bully-victims with CVA had about 19-fold higher odds of suicidal feelings compared with uninvolved adolescents without CVA. This study, although correlational, suggested that CVA avoidance might prevent bullying involvement and suicidal feelings in adolescents. PMID:27711150

    Serine protease thrombin, a key factor of blood coagulation, participates in many neuronal processes important for normal brain functioning and during pathological conditions involving abnormal neuronal synchronization, neurodegeneration and inflammation. Our previous study on CA3 pyramidal neurons showed that application ofthrombin through the activation of specific protease-activated receptor 1 (PAR1) produces a significant hyperpolarizing shift of the activation of the TTX-sensitive persistent voltage-gated Na+ current (I(Nap)) thereby affecting membrane potential and seizure threshold at the network level. It was shown that PAR1 is also expressed in CA1 area of hippocampus and can be implicated in neuronal damage in this area after status epilepticus. The aim of the present study was to evaluate the effect of thrombin on I(NaP) in CA1 pyramidal neurons from adult and young rats. Using whole cell patch-clamp technique we demonstrate that thrombin application results in the hyperpolarization shift of I(NaP) activation as well as increase in the I(NaP) amplitude in both age groups. We have found that I(NaP) in pyramidal neurons of hippocampal CA 1 region is more vulnerable to the thrombin action than I(NaP) in pyramidal neurons of hippocampal CA3 region. We have also found that the immature hippocampus is more sensitive to thrombin action which emphasizes the contribution of thrombin-dependent pathway to the regulation of neuronal activity in immature brain.

    2013-01-01

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

    Although over 1.5 million African immigrants live in the US, few studies have examined the relationship of language acculturation to health outcomes among African immigrant adults. The primary objective of this research was to investigate the relationship between English proficiency and current self-rated health among African immigrant adults. Using a cross-sectional design, a secondary data analysis was performed on baseline data from the African immigrant adult subsample (n = 763) of the 2003 New Immigrant Survey, a longitudinal study of lawful permanent residents. Limited English proficiency (LEP), increased duration of US residence, older age at immigration, being male, less than 12 years of education, poor pre-migration health, and chronic disease were associated with good/fair/poor current self-rated health. Findings support consideration of pre-migration health and chronic disease in future acculturation and health studies, and provision of linguistically competent interventions for LEP African immigrants at risk for poor health outcomes.

    Purpose Overweight and underweight conditions are considered relative contraindications to lung transplantation due to their association with excess mortality. Yet, recent work suggests that body mass index (BMI) does not accurately reflect adipose tissue mass in adults with advanced lung diseases. Alternative and more accurate measures of adiposity are needed. Chest fat estimation by routine computed tomography (CT) imaging may therefore be important for identifying high-risk lung transplant candidates. In this paper, an approach to chest fat quantification and quality assessment based on a recently formulated concept of standardized anatomic space (SAS) is presented. The goal of the paper is to seek answers to several key questions related to chest fat quantity and quality assessment based on a single slice CT (whether in the chest, abdomen, or thigh) versus a volumetric CT, which have not been addressed in the literature. Methods Unenhanced chest CT image data sets from 40 adult lung transplant candidates (age 58 ± 12 yrs and BMI 26.4 ± 4.3 kg/m2), 16 with chronic obstructive pulmonary disease (COPD), 16 with idiopathic pulmonary fibrosis (IPF), and the remainder with other conditions were analyzed together with a single slice acquired for each patient at the L5 vertebral level and mid-thigh level. The thoracic body region and the interface between subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) in the chest were consistently defined in all patients and delineated using Live Wire tools. The SAT and VAT components of chest were then segmented guided by this interface. The SAS approach was used to identify the corresponding anatomic slices in each chest CT study, and SAT and VAT areas in each slice as well as their whole volumes were quantified. Similarly, the SAT and VAT components were segmented in the abdomen and thigh slices. Key parameters of the attenuation (Hounsfield unit (HU) distributions) were determined from each chest slice and

  16. Predicting the efficacy of trastuzumab-based therapy in breast cancer: current standards and future strategies.

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

    Automatic tube current modulation (TCM) is used in modern CT devices. This is implemented in the numerical calculation of dose conversion coefficients for CT examinations. For four models of adults, the female and male reference models of ICRP and ICRU and a lighter and a heavier female model, dose conversion coefficients normalized to CTDI{sub vol} (DCC{sup CT}) have been computed with a Monte Carlo transport code for CT scans with and without TCM. It could be shown for both cases that reliable values for spiral CT scans are obtained when combining the results from an appropriate set of axial scans. The largest organ DCC{sup CT} are presented for typical CT examinations for all four models. The impact of TCM is greatest for chest, pelvis and whole-trunk CT examinations, where with TCM the effective DCC{sup CT} can be 20-25% lower than without TCM. Typical organs with strong dependence on TCM are thyroid, urinary bladder, lungs and oesophagus. While the DCC{sup CT} of thyroid and urinary bladder are mainly sensitive to angular TCM, the DCC{sup CT} of lungs and oesophagus are influenced primarily by longitudinal TCM. The impact of the body stature on the effective DCC{sup CT} is of the same order as the effect of TCM. Thus, for CT scans in the trunk region, accurate dose values can only be obtained when different sets of DCC{sup CT} are employed that are appropriate for the patient's sex and stature and the actual TCM settings.

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

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

  8. Effects of transcranial direct current stimulation on the control of finger force during dexterous manipulation in healthy older adults.

    Directory of Open Access Journals (Sweden)

    Pranav J Parikh

    Full Text Available The contribution of poor finger force control to age-related decline in manual dexterity is above and beyond ubiquitous behavioral slowing. Altered control of the finger forces can impart unwanted torque on the object affecting its orientation, thus impairing manual performance. Anodal transcranial direct current stimulation (tDCS over primary motor cortex (M1 has been shown to improve the performance speed on manual tasks in older adults. However, the effects of anodal tDCS over M1 on the finger force control during object manipulation in older adults remain to be fully explored. Here we determined the effects of anodal tDCS over M1 on the control of grip force in older adults while they manipulated an object with an uncertain mechanical property. Eight healthy older adults were instructed to grip and lift an object whose contact surfaces were unexpectedly made more or less slippery across trials using acetate and sandpaper surfaces, respectively. Subjects performed this task before and after receiving anodal or sham tDCS over M1 on two separate sessions using a cross-over design. We found that older adults used significantly lower grip force following anodal tDCS compared to sham tDCS. Friction measured at the finger-object interface remained invariant after anodal and sham tDCS. These findings suggest that anodal tDCS over M1 improved the control of grip force during object manipulation in healthy older adults. Although the cortical networks for representing objects and manipulative actions are complex, the reduction in grip force following anodal tDCS over M1 might be due to a cortical excitation yielding improved processing of object-specific sensory information and its integration with the motor commands for production of manipulative forces. Our findings indicate that tDCS has a potential to improve the control of finger force during dexterous manipulation in older adults.

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

    This study tested for links among behaviour, state and life-history variables as predicted by the pace-of-life hypothesis in adult pike Esox lucius. First, a standardized open-field behavioural assay was developed to assess individual behaviour of wild-captured adult E. lucius. Behaviour within the standardized assay predicted swimming behaviour in the lake, providing an ecological validation of the assay. There was no relationship between standardized behaviour and any of the life-history and state variables, including metabolism, body condition, juvenile growth rate and adult growth rate in contrast to predictions from the pace-of-life hypothesis. This study demonstrates that it is possible to assess ecologically relevant behavioural variation in a large-bodied top predator using a standard open-field assay, but it is noteworthy that this standardized behaviour is not systematically related to standard metabolism or growth.

Two sets of high resolution numerical phantoms of different size (REMCOM/Hershey and Virtual Family), simulating adult and child bodies, are exposed to a 10 MHz pass-by panel-type EAS consisting of two overlapping current-carrying coils. Two different relative positions between the EAS and the body (frontal and lateral exposures), which imply the exposure of different parts of the body at different distances, have been considered. In all cases, induced current densities in tissues of the central nervous system and specific absorption rates (SARs) are calculated to be compared with the limits from the guidelines. Results show that induced current densities are lower in the case of adult models as compared with those of children in both lateral and frontal exposures. Maximum SAR values calculated in lateral exposure are significantly lower than those calculated in frontal exposure, where the EAS-body distance is shorter. Nevertheless, in all studied cases, with an EAS driving current of 4 A rms, maximum induced current and SAR values are below basic restrictions.

    2017-01-01

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

    Stem cells represent a promising step for the future of regenerative medicine. As they are able to differentiate into any cell type, tissue or organ, these cells are great candidates for treatments against the worst diseases that defy doctors and researchers around the world. Stem cells can be divided into three main groups: (1) embryonic stem cells; (2) fetal stem cells; and (3) adult stem cells. In terms of their capacity for proliferation, stem cells are also classified as totipotent, pluripotent or multipotent. Adult stem cells, also known as somatic cells, are found in various regions of the adult organism, such as bone marrow, skin, eyes, viscera and brain. They can differentiate into unipotent cells of the residing tissue, generally for the purpose of repair. These cells represent an excellent choice in regenerative medicine, every patient can be a donor of adult stem cells to provide a more customized and efficient therapy against various diseases, in other words, they allow the opportunity of autologous transplantation. But in order to start clinical trials and achieve great results, we need to understand how these cells interact with the host tissue, how they can manipulate or be manipulated by the microenvironment where they will be transplanted and for how long they can maintain their multipotent state to provide a full regeneration.

    2016-09-01

    Autoimmune diabetes has a heterogeneous phenotype. Although often considered a condition starting in childhood, a substantial proportion of type 1 diabetes presents in adult life. This holds important implications for our understanding of the factors that modify the rate of progression through the disease prodrome to clinical diabetes and for our management of the disease. When autoimmune diabetes develops in adulthood, insulin treatment is often not required at the time of diagnosis, and this autoimmune non-insulin requiring diabetes is generally termed latent autoimmune diabetes in adults (LADA). Patients with LADA are generally leaner, younger at diabetes onset; have a greater reduction in C-peptide; and have a greater likelihood of insulin treatment as compared with patients with type 2 diabetes. The LADA subset of patients with adult-onset autoimmune diabetes has highlighted many shortcomings in the classification of diabetes and invokes the case for more personalized data analysis in line with the move towards precision medicine. Perhaps most importantly, the issues highlight our persistent failure to engage with the heterogeneity within the most common form of autoimmune diabetes, that is adult-onset type 1 diabetes, both insulin-dependent and initially non-insulin requiring (LADA). This review discusses characteristics of autoimmune diabetes and specifically aims to illustrate the heterogeneity of the disease.

    Technologies have become a major force in people's lives. They change how people interact with the environment, even as the environment changes. We propose that technology use in the setting of changing environments is motivated by essential needs and tensions experienced by the individual. We apply three developmental and behavioral theories (Erikson's stages of psychosocial development, Maslow's hierarchy of needs, and Bronfenbrenner's ecological model) to explain technology-related behaviors among older adults. We consider how technology use has addressed and can address major ecological changes, in three areas: health promotion, natural disasters, and disparities. We propose that considering these theories can help researchers and developers ensure that technologies will help promote a healthier world for older adults.

  12. Adult subependymal neural precursors, but not differentiated cells, undergo rapid cathodal migration in the presence of direct current electric fields.

    Directory of Open Access Journals (Sweden)

    Robart Babona-Pilipos

    Full Text Available BACKGROUND: The existence of neural stem and progenitor cells (together termed neural precursor cells in the adult mammalian brain has sparked great interest in utilizing these cells for regenerative medicine strategies. Endogenous neural precursors within the adult forebrain subependyma can be activated following injury, resulting in their proliferation and migration toward lesion sites where they differentiate into neural cells. The administration of growth factors and immunomodulatory agents following injury augments this activation and has been shown to result in behavioural functional recovery following stroke. METHODS AND FINDINGS: With the goal of enhancing neural precursor migration to facilitate the repair process we report that externally applied direct current electric fields induce rapid and directed cathodal migration of pure populations of undifferentiated adult subependyma-derived neural precursors. Using time-lapse imaging microscopy in vitro we performed an extensive single-cell kinematic analysis demonstrating that this galvanotactic phenomenon is a feature of undifferentiated precursors, and not differentiated phenotypes. Moreover, we have shown that the migratory response of the neural precursors is a direct effect of the electric field and not due to chemotactic gradients. We also identified that epidermal growth factor receptor (EGFR signaling plays a role in the galvanotactic response as blocking EGFR significantly attenuates the migratory behaviour. CONCLUSIONS: These findings suggest direct current electric fields may be implemented in endogenous repair paradigms to promote migration and tissue repair following neurotrauma.

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

    ABSTRACT The zebrafish (Danio rerio) is an increasingly popular model organism in cardiovascular research. Major insights into cardiac developmental processes have been gained by studies of embryonic zebrafish. However, the utility of zebrafish for modeling adult-onset heart disease has been limited by a lack of robust methods for in vivo evaluation of cardiac function. We established a physiological protocol for underwater zebrafish echocardiography using high frequency ultrasound, and evaluated its reliability in detecting altered cardiac function in two disease models. Serial assessment of cardiac function was performed in wild-type zebrafish aged 3 to 12 months and the effects of anesthetic agents, age, sex and background strain were evaluated. There was a varying extent of bradycardia and ventricular contractile impairment with different anesthetic drugs and doses, with tricaine 0.75 mmol l−1 having a relatively more favorable profile. When compared with males, female fish were larger and had more measurement variability. Although age-related increments in ventricular chamber size were greater in females than males, there were no sex differences when data were normalized to body size. Systolic ventricular function was similar in both sexes at all time points, but differences in diastolic function were evident from 6 months onwards. Wild-type fish of both sexes showed a reliance on atrial contraction for ventricular diastolic filling. Echocardiographic evaluation of adult zebrafish with diphtheria toxin-induced myocarditis or anemia-induced volume overload accurately identified ventricular dilation and altered contraction, with suites of B-mode, ventricular strain, pulsed-wave Doppler and tissue Doppler indices showing concordant changes indicative of myocardial hypocontractility or hypercontractility, respectively. Repeatability, intra-observer and inter-observer correlations for echocardiographic measurements were high. We demonstrate that high

    Full Text Available Background: Parenteral nutrition (PN is a costly therapy that can also be associated with serious complications. Therefore, efforts are focusing on reducing rate of complications, and costs related to PN. Objective: The aim was to analyze the effect of the implementation of PN standardization on costs and quality criteria. Secondary aim was to assess the use of individualized PN based on patient's clinical condition. Methods: We compare the use of PN before and after the implementation of PN standardization. Demographic, clinical and PN characteristics were collected. Costs analysis was performed to study the costs associated to the two different periods. Quality criteria included were: 1 PN administration; 2 nutrition assessment (energy intake between 20-35 kcal/kg/day; protein contribution according to nitrogen balance; 3 safety and complications (hyperglycemia, hypertriglyceridemia, hepatic complications, catheter-related infection; 4 global efficacy (as serum albumin increase. Chi-square test was used to compare percentages; logistic regression analysis was performed to evaluate the use of customized PN. Results: 296 patients were included with a total of 3,167 PN compounded. During the first period standardized PN use was 47.5% vs 85.7% within the second period (p < 0.05. No differences were found in the quality criteria tested. Use of individualized PN was related to critical care patients, hypertriglyceridemia, renal damage, and long-term PN. Mean costs of the PN decreased a 19.5%. Annual costs savings would be € 86,700. Conclusions: The use of customized or standard PN has shown to be efficient and flexible to specific demands; however customized PN was significantly more expensive.

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

  1. Current data with inulin-type fructans and calcium, targeting bone health in adults.

    In humans, there is increasing evidence that the colon can absorb nutritionally significant amounts of calcium, and this process may be susceptible to dietary manipulation by fermentable substrates, especially inulin-type fructans. Inulin-type fructans can modulate calcium absorption because they are resistant to hydrolysis by mammalian enzymes and are fermented in the large intestine to produce short-chain fatty acids, which in turn reduce luminal pH and modify calcium speciation, and hence solubility, or exert a direct effect on the mucosal transport pathway. Quite a few intervention studies showed an improvement of calcium absorption in adolescents or young adults by inulin-type fructans. In the same way, a positive effect has been reported in older women.

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

  3. Synaptic NMDA receptor-mediated currents in anterior piriform cortex are reduced in the adult fragile X mouse.

    Gocel, James; Larson, John

    2012-09-27

    Fragile X syndrome is a neurodevelopmental condition caused by the transcriptional silencing of the fragile X mental retardation 1 (FMR1) gene. The Fmr1 knockout (KO) mouse exhibits age-dependent deficits in long term potentiation (LTP) at association (ASSN) synapses in anterior piriform cortex (APC). To investigate the mechanisms for this, whole-cell voltage-clamp recordings of ASSN stimulation-evoked synaptic currents were made in APC of slices from adult Fmr1-KO and wild-type (WT) mice, using the competitive N-methyl-D-aspartate (NMDA) receptor antagonist, CPP, to distinguish currents mediated by NMDA and AMPA receptors. NMDA/AMPA current ratios were lower in Fmr1-KO mice than in WT mice, at ages ranging from 3-18months. Since amplitude and frequency of miniature excitatory postsynaptic currents (mEPSCs) mediated by AMPA receptors were no different in Fmr1-KO and WT mice at these ages, the results suggest that NMDA receptor-mediated currents are selectively reduced in Fmr1-KO mice. Analyses of voltage-dependence and decay kinetics of NMDA receptor-mediated currents did not reveal differences between Fmr1-KO and WT mice, suggesting that reduced NMDA currents in Fmr1-KO mice are due to fewer synaptic receptors rather than differences in receptor subunit composition. Reduced NMDA receptor signaling may help to explain the LTP deficit seen at APC ASSN synapses in Fmr1-KO mice at 6-18months of age, but does not explain normal LTP at these synapses in mice 3-6months old. Evoked currents and mEPSCs were also examined in senescent Fmr1-KO and WT mice at 24-28months of age. NMDA/AMPA ratios were similar in senescent WT and Fmr1-KO mice, due to a decrease in the ratio in the WT mice, without significant change in AMPA receptor-mediated mEPSCs.

  4. Re: Current Standard Technique for Modern Flexible Ureteroscopy: Tips and Tricks

    Full Text Available The prevalence of urinary stone disease is increasing worldwide. The dissemination of the clinical use of ultrasound has improved the diagnosis of stones at an earlier stage. It has increased the expansion of the indications of flexible ureterorenoscopy (fURS. With the advances in flexible ureteroscopy (FU, more successful outcomes are being reported. The most recent EAU guidelines state that for all stones smaller than 2 cm, fURS can be the first choice of treatment. Especially for lower pole stones, the stone free rate is better than that with extracorporeal shock wave lithotripsy. For stones larger than 2 cm staged procedures may be necessary. This paper recommends a standardized technique for fURS to decrease the rate of possible complications, and increase the success rate. Endourological techniques are widely adopted by most of the urological surgeons, hence fURS is an expansion of our surgical armamentarium. In this paper, an experienced group recommends some tips and tricks for each step of the procedure. The authors recommend general anesthesia over spinal anesthesia for two reasons: larger tidal volume during spinal anesthesia may cause movement, which can make the procedure harder. Secondly, the duration of the spinal anesthesia may be too short for some cases. The placement of ureteral access sheath (UAS should be done under fluoroscopic guidance and proper force should be applied.

    Full Text Available EDITORIAL COMMENT The prevalence of urinary stone disease is increasing worldwide. The dissemination of the clinical use of the ultrasound has increased the rate of diagnosis of stones at an earlier stage, thus, has increased the expansion of the indications for flexible ureterorenoscopy (fURS. With the advancements in flexible ureteroscopy (FU, more successful outcomes are being reported. The most recent EAU guidelines state that fURS can be the first choice of treatment for all stones smaller than 2 cm. Especially for the lower pole stones, the stone-free rate is better than that with extracorporeal shock wave lithotripsy. For stones larger than 2 cm, staged procedures may be necessary. This paper recommends a standardized technique for fURS which is aimed to decrease the rate of possible complications and increase the success rate. Endourological techniques are widely adopted by most of the urological surgeons, hence fURS is an expansion of our surgical armamentarium. In this paper, an experienced group recommended some tips and tricks for each step of the procedure. The authors recommended general anesthesia over spinal anesthesia for two reasons: larger tidal volume during spinal anesthesia may cause movement, which can make the procedure harder. Secondly, the duration of the spinal anesthesia may be too short for some cases. Placement of ureteral access sheath (UAS should be done under fluoroscopic guidance and proper force should be applied. Ideally, the distal tip of the UAS should be just below the ureteropelvic junction. For preventing functional deterioration of the FU, the tip of the laser probe should be out of the scope as far as one-quarter of the screen diameter. For preventing excessive prolonged deflections, the stones in the lower pole should be repositioned in order to allow a more straight working channel. Pulverization of the stone is preferred over fragmentation since it decreases the operative time and risk of injury

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

    Full Text Available The diagnosis and treatment of diabetic retinopathy (DR in young adults have significantly improved in recent years. Research methods have widened significantly, for example, by introducing spectral optical tomography of the eye. Invasive diagnostics, for example, fluorescein angiography, are done less frequently. The early introduction of an insulin pump to improve the administration of insulin is likely to delay the development of diabetic retinopathy, which is particularly important for young patients with type 1 diabetes mellitus (T1DM. The first years of diabetes occurring during childhood and youth are the most appropriate to introduce proper therapeutic intervention before any irreversible changes in the eyes appear. The treatment of DR includes increased metabolic control, laserotherapy, pharmacological treatment (antiangiogenic and anti-inflammatory treatment, enzymatic vitreolysis, and intravitreal injections, and surgery. This paper summarizes the up-to-date developments in the diagnostics and treatment of DR. In the literature search, authors used online databases, PubMed, and clinitrials.gov and browsed through individual ophthalmology journals, books, and leading pharmaceutical company websites.

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

    2014-09-01

    The presence of pulmonary arterial hypertension (PAH) increases morbidity and reduces survival in patients with congenital heart disease (CHD). PAH-CHD is a heterogeneous condition, depending on the type of the underlying defect and previous repair strategies. There is growing evidence of the benefits of PAH-specific therapy in the PAH-CHD population, but despite recent advances mortality rates remain relatively high. In the last years, an increasing focus has been placed on patients with PAH-CHD and net left-to-right shunt. Currently, there are limited data to guide the management of these patients and uncertainty on the cut-off values for eventual defect closure. Pregnancy conveys significant risks in PAH-CHD patients: appropriate counselling and care, including psychological support and a multidisciplinary team, should be part of the routine management of women with PAH-CHD of reproductive age. Some subgroups, such as patients with Down's syndrome, Fontan circulation and 'segmental' pulmonary hypertension, present particular challenges in terms of management and therapy. The current review focuses on contemporary treatment strategies in PAH-CHD patients with particular emphasis on challenging patient groups and conditions.

    Current psychopharmacological approaches to reduce psychotic phenomenology in schizophrenia are associated with adverse effects including extrapyramidal and metabolic side effects. In view of the emerging data on nutritional supplementation interventions in schizophrenia which are not entirely consistent, we aimed to review existent studies focusing on fatty acid and vitamin interventions and summarise current evidence on such nutritional supplementations in schizophrenia. We searched the digital databases (ScienceDirect, Scopus, SpringerLINK, PubMed/Medline) for relevant studies pertaining to fatty acid and vitamin supplementation interventions in the management of psychotic symptoms in schizophrenia up to February 2015. Overall, there were more studies conducted on fatty acid over vitamin supplementations in patients with schizophrenia. There were more positive findings in support of fatty acid supplementation compared with vitamin supplementation in the context of specific intervention features (dose of nutrient supplementation, single versus combination nutritional interventions, specific antipsychotic), subject features (older age, long duration of illness, baseline polyunsaturated fatty acid levels) and clinical outcomes (improvements of psychotic symptoms and/or extrapyramidal side effects from antipsychotics). However, investigations of both supplementation modalities were limited by relatively small study sample sizes, short study duration, which precluded further segmentation of impact on more diverse patient subtypes and symptom profiles. Future studies may consider examining larger samples over a longer time period, recruiting younger subjects with shorter duration of illness, examination of different clinical features including specific cognitive domains, and use of single versus combination nutritional interventions.

    2014-10-01

    Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disorder whose prevalence is strongly linked to the current epidemic of obesity in many western countries. The prevalence of NAFLD is two to four times higher in populations with pre-existing metabolic comorbidities than in the general population. The diagnosis of primary NAFLD involves establishing the presence of hepatic steatosis or steatohepatitis by imaging or histology, along with establishing the non-alcoholic nature of the disease process and excluding competing aetiologies for hepatic steatosis. Among the indirect serum biomarkers, the NAFLD fibrosis score can help to identify patients with NAFLD and with higher likelihood of having fibrosis or cirrhosis. A liver biopsy should be considered in NAFLD patients at increased risk for steatohepatitis/advanced fibrosis and in cases where a liver biopsy is necessary to exclude co-existing chronic liver diseases and other aetiologies for hepatic steatosis. The treatment and management recommendations for obesity-associated NAFLD are aimed towards weight reduction. The currently available interventions employed to promote weight loss and improve the metabolic responses in NAFLD include lifestyle modification, pharmacotherapy and bariatric surgery.

    The games that adolescents and young people used to play in the play grounds and on the streets have been replaced in recent years with cyber games played in front of the computer on the internet or in game arcades. This changing culture has particularly brought up the concept of "digital game addiction", a condition that stems from the steadily growing passion for digital games and their excessived and uncontrolled usage among adolescents and young people. Game addiction in the psychiatry literature has been described as an impulse control disorder characterized by the symptoms such as "the inability to control the time spent on game-playing", "a loss of interest in other activities", "continuing to play despite the adverse effects" and "feeling psychologically deprived when not being able to play"."Although digital game addiction has not been accepted by psychiatric authorities as a psychiatric disorder yet, the increasing psychiatry referrals due to the problems accompanying this disorder, the efforts of families to seek support and solutions, the evidence that similarities with other types of addiction have been revealed by researchers, as well as the current prevalence rates are all factors that suggest the existence of important of the examination of issue. Despite the discussions about the digital game addiction, the literature on the subject is increasing. This article offers an overview of digital game-playing behavior in the light of current literature, seeking to share its findings with health care professionals.

    Renal biopsy remains the golden standard diagnosis of renal function deterioration. The safety in native kidney biopsy is well defined. However, it is a different story in allograft kidney biopsy. We conduct this retrospective study to clarify the safety of allograft kidney biopsy with indication.All variables were grouped by the year of biopsy and they were compared by Mann-Whitney U test (for continuous variables) or Chi-square test (for categorical variables). We collected possible factors associated with complications, including age, gender, body weight, renal function, cause of uremia, status of coagulation, hepatitis, size of needle, and immunosuppressants.We recruited all renal transplant recipients undergoing allograft biopsy between January of 2009 and December of 2014. This is the largest database for allograft kidney biopsy with indication. Of all the 269 biopsies, there was no difference in occurrence among the total 14 complications (5.2%) over these 6 years. There were only 3 cases of hematomas (1.11%), 6 gross hematuria (2.23%), 1 hydronephrosis (0.37%), and 2 hemoglobin decline (0.74%). The outcome of this cohort is the best compared to all other studies, and it is even better than the allograft protocol kidney biopsy. Among all possible factors, patients with pathological report containing "medullary tissue only" were susceptible to complications (P biopsy with indication. Identifying the renal capsule before biopsy to avoid puncture into medulla is the most important element to prevent complications.

  16. Managing chronic pain in adults with haemophilia: current status and call to action.

    Humphries, T J; Kessler, C M

    2015-01-01

    Haemophilic arthroses are associated with acute pain during bleeding episodes and with chronic pain caused by arthritic complications of repeated bleeding into joints. Unlike other conditions (e.g. osteoarthritis, rheumatoid arthritis, sickle cell disease), there are limited data on pain management in haemophilia. Management of arthritic individuals and those with sickle cell disease relies heavily on administration of acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs) and opioid analgesics. In haemophilia, acetaminophen often has limited efficacy at therapeutic doses, offering a narrow dosing range in those with liver disease due to chronic hepatitis C. NSAIDs can effectively manage pain in patients with haemophilia, but these agents are potentially associated with a significant risk of precipitating or exacerbating bleeding complications in an already coagulopathic population. Opioids have proven effective in osteoarthritis and sickle cell disease, but outcomes data in those with haemophilia are virtually non-existent. Patients with haemophilia are at least as vulnerable as other chronic pain populations to opioid-related adverse events and to developing abusive behaviours and addiction. Despite pain management strategies for patients with haemophilia being far from optimal, the predominant precept of haemophilia management still applies. As such, it is critically important to aggressively reverse or prevent acute symptomatic bleeding in a timely and effective manner to at least minimize pain and progressive joint damage. This review should serve as a call to action to prioritize pain management in haemophilia care and spur interest in the development, improvement and standardization of tools to assess and manage acute and chronic pain in haemophilia.

    Purpose: Osteoblasts are capable to produce different compounds directly connected to bone mineralization process. This study aims to standardize the reverse transcriptase polymerase chain reaction (RT-PCR) for adult osteoblasts to observe the effect of low level laser therapy on bone mineralization. Methods: Five-millimeter long fragments obtained from the mead femoral region of male Wistar rats were assigned into group A (n=10, laser) and group B (n=10, no laser), submitted to mechanic and enzymatic digestion. After 7 days, cultures of group A were irradiated daily on a single spot with a GaInAs laser, λ=808nm, 200mW/cm2, 2J/cm2, bean diameter of 0,02mm, 5 seconds for 6 days. Group B was manipulated but received no laser irradiation. After 13 days the cells were trypsinized for 15 minute and stabilized with RNA later® for RNA extraction with Trizol®. cDNA synthesis used 10μg of RNA and M-MLV® enzyme. PCR was accomplished using the β-actin gene as a control. Another aliquot was fixed for Hematoxylin-Eosin and Von Kossa staining to visualize bone mineralization areas. Results: Under UV light we observed clearly the amplification of β-actin gene around 400bp. HE and Von Kossa staining showed osteoblast clusters, a higher number of bone cells and well defined mineralization areas in group A. Conclusion: The cell culture, RNA extraction and RT-PCR method for adult osteoblasts was effective, allowing to use these methods for bone mineralization studies. Laser improved bone mineralization and further studies are needed involving osteogenesis, calcium release mechanisms and calcium related channels.

    Cystic fibrosis (CF) is one of the most frequent monogenic disease in the Caucasian population, inherited in an autosomal recessive pattern. This is a multiple organ disease and its main manifestations include pulmonary and gastrointestinal dysfunction. The exocrine pancreatic deficiency results in impaired digestion and absorption what may lead to malnutrition and vitamins and minerals deficiencies. The life expectancy of cystic fibrosis patients has been increasing over the past years, so there is a need to verify usefulness of existing or create new methods of nutritional status assessment. The aim of this paper was presentation current data on the methods of assessment and monitoring of nutritional status. Particular attention has been paid to appropriate nutritional support in prevention and treatment of malnutrition patients with cystic fibrosis. On the basis of recent literature we can conclude that the advanced nutritional status assessment is recommended in patient with CF by using anthropometrical methods, body composition analysis and biochemical data. Good nutritional status is connected with pulmonary functions, quality and life length.

    This review discusses available laboratory and clinical data as well as recent advances in our knowledge about prognostic factors and their implications for the design of future clinical trials. Results: Elucidation of the biology of malignant astrocytomas allowed for development of rational new approaches, such as gene therapy and immunotherapy, which could interfere with established treatment regimens or being used independently. Possible strategies include the restoration of defective cancer-inhibitory genes, cell transduction or transfection with antisense DNA corresponding to genes coding for growth factors and their receptors, or with the so-called suicide genes. Several antiangiogenic approaches such as administration of thalidomide, protamine, or monoclonal antibodies against vascular endothelial growth factor have been developed, too. Further treatment possibilities include modulation of drug resistance, e.g. by P-glycoprotein antagonists or O6-alkyl-guanine-DNA-transferase inhibitors, inhibition of matrix metalloproteinases, inhibition of protein kinase C, and administration of agents such as phenylbutyrate or valproic acid that showed promising antiproliferative effects in vitro. Conclusions: Several rational new approaches are now entering clinical trials. In the light of limited survival after standard treatment it is recommended that patients should be offered participation in such trials. (orig.)

    2015-01-01

    New information has become available since the ISC, AAMCC, and SECAC released their first extensive guidedelines to improve the diagnosis and treatment of adult arterial hypertension. A critical assessment of evidence and a comparison of what international guidelines now propose are the basis for the following statements, which update the recommendations first issued in 2013. Office blood pressure (BP) measurements should no longer be considered to be the "gold standard" for the diagnosis of hypertension and assessment of cardiovascular risk. Relying on office BP, even when supplemented with at-home wake-time self-measurements, to identify high-risk individuals, disregarding circadian BP patterning and asleep BP level, leads to potential misclassification of 50% of all evaluated persons. Accordingly, ambulatory BP monitoring is the recommended reference standard for the diagnosis of true hypertension and accurate assessment of cardiovascular risk in all adults ≥18 yrs of age, regardless of whether office BP is normal or elevated. Asleep systolic BP mean is the most significant independent predictor of cardiovascular events. The sleep-time relative SBP decline adds prognostic value to the statistical model that already includes the asleep systolic BP mean and corrected for relevant confounding variables. Accordingly, the asleep systolic BP mean is the recommended protocol to diagnose hypertension, assess cardiovascular risk, and predict cardiovascular event-free interval. In men, and in the absence of compelling clinical conditions, reference thresholds for diagnosing hypertension are 120/70 mmHg for the asleep systolic/diastolic BP means derived from ambulatory BP monitoring. However, in women, in the absence of complicating co-morbidities, the same thresholds are lower by 10/5 mmHg, i.e., 110/65 mmHg for the asleep means. In high-risk patients, including those diagnosed with diabetes or chronic kidney disease, and/or those having experienced past

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

    In clinical trials, sofosbuvir showed high antiviral activity in patients infected with hepatitis C virus (HCV) across all genotypes. We aimed to determine the cost-effectiveness of sofosbuvir-based treatment compared to current standard treatment in mono-infected patients with chronic hepatitis C (CHC) genotypes 1-4 in Switzerland. Cost-effectiveness was modelled from the perspective of the Swiss health care system using a lifetime Markov model. Incremental cost-effectiveness ratios (ICERs) used an endpoint of cost per quality-adjusted life year (QALY) gained. Treatment characteristics, quality of life, and transition probabilities were obtained from published literature. Country-specific model inputs such as patient characteristics, mortality and costs were obtained from Swiss sources. We performed extensive sensitivity analyses. Costs and effects were discounted at 3% (range: 0-5%) per year. Sofosbuvir-containing treatment in mixed cohorts of cirrhotic and non-cirrhotic patients with CHC genotypes 1-4 showed ICERs between CHF 10,337 and CHF 91,570 per QALY gained. In subgroup analyses, sofosbuvir dominated telaprevir- and boceprevir-containing treatment in treatment-naïve genotype 1 cirrhotic patients. ICERs of sofosbuvir were above CHF 100,000 per QALY in treatment-naïve, interferon eligible, non-cirrhotic patients infected with genotypes 2 or 3. In deterministic and probabilistic sensitivity analyses, results were generally robust. From a Swiss health care system perspective, treatment of mixed cohorts of cirrhotic and non-cirrhotic patients with CHC genotypes 1-4 with sofosbuvir-containing treatment versus standard treatment would be cost-effective if a threshold of CHF 100,000 per QALY was assumed.

Costs and effects were discounted at 3% (range: 0-5% per year. Sofosbuvir-containing treatment in mixed cohorts of cirrhotic and non-cirrhotic patients with CHC genotypes 1-4 showed ICERs between CHF 10,337 and CHF 91,570 per QALY gained. In subgroup analyses, sofosbuvir dominated telaprevir- and boceprevir-containing treatment in treatment-naïve genotype 1 cirrhotic patients. ICERs of sofosbuvir were above CHF 100,000 per QALY in treatment-naïve, interferon eligible, non-cirrhotic patients infected with genotypes 2 or 3. In deterministic and probabilistic sensitivity analyses, results were generally robust. From a Swiss health care system perspective, treatment of mixed cohorts of cirrhotic and non-cirrhotic patients with CHC genotypes 1-4 with sofosbuvir-containing treatment versus standard treatment would be cost-effective if a threshold of CHF 100,000 per QALY was assumed.

    Late Na(+) current (I(NaL)) is a major component of the action potential plateau in human and canine myocardium. Since I(NaL) is increased in heart failure and ischemia, it represents a novel potential target for cardioprotection. However, the molecular identity of I(NaL) remains unclear. We tested the hypothesis that the cardiac Na(+) channel isoform (Na(v)1.5) is a major contributor to I(NaL) in adult dog ventricular cardiomyocytes (VCs). Cultured VCs were exposed to an antisense morpholino-based oligonucleotide (Na(v)1.5 asOligo) targeting the region around the start codon of Na(v)1.5 mRNA or a control nonsense oligonucleotide (nsOligo). Densities of both transient Na(+) current (I(NaT)) and I(NaL) (both in pA/pF) were monitored by whole cell patch clamp. In HEK293 cells expressing Na(v)1.5 or Na(v)1.2, Na(v)1.5 asOligo specifically silenced functional expression of Na(v)1.5 (up to 60% of the initial I(NaT)) but not Na(v)1.2. In both nsOligo-treated controls and untreated VCs, I(NaT) and I(NaL) remained unchanged for up to 5 days. However, both I(NaT) and I(NaL) decreased exponentially with similar time courses (tau = 46 and 56 h, respectively) after VCs were treated with Na(v)1.5 asOligo without changes in 1) decay kinetics, 2) steady-state activation and inactivation, and 3) the ratio of I(NaL) to I(NaT). Four days after exposure to Na(v)1.5 asOligo, I(NaT) and I(NaL) amounted to 68 +/- 6% (mean +/- SE; n = 20, P < 0.01) and 60 +/- 7% (n = 11, P < 0.018) of those in VCs treated by nsOligo, respectively. We conclude that in adult dog heart Na(v)1.5 sodium channels have a "functional half-life" of approximately 35 h (0.69tau) and make a major contribution to I(NaL).

    This literature review outlines the current issues and debates relating to the dental health of adults with drug dependence. The dental health of adults with illegal drug dependence (IDD) continues to be under debate throughout dental practice, and the most appropriate model of care suitable to meet the high complex needs of this client group remains uncertain. The study aims to review and critically analyze available research relating to the oral health effects of illegal drug misuse and the dental health needs and status of adults with drug dependence. Second, it aims to identify and critically evaluate current models of dental service/care delivery, including relevant best practice guidance and potential barriers to dental access for adults with IDD. The available literature pertaining to dental health and adults with drug dependence are systematically reviewed and critically analyzed and evaluated in order to execute a rigorous investigation. The oral effects along with general medical complications associated with IDD are increasingly being recognized. There are substantive negative effects of IDD on oral health, particularly for those with opioid dependence; therefore, these clients have high complex dental needs and low use of dental services. Adults with drug dependence comprise a group with special dental needs and therefore need greater access to dental care than most people due to their high level of need. A high awareness of the implications for oral health care for adults with drug dependence is essential. Dental professionals have a key role in supporting the rehabilitation of these patients from potentially severe or fatal addictions. There is a distinct lack of national policy and guidance relating specifically to adults with drug dependence, and therefore, problems persist. Key findings and recommendations are presented to enhance the development of dental services for adults with IDD.

    Full Text Available Bacterial pneumonia is a leading cause of illness and death worldwide, but quantifying its burden is difficult due to insensitive diagnostics. Although World Health Organization (WHO protocol standardizes pediatric chest radiograph (CXR interpretation for epidemiologic studies of bacterial pneumonia, its validity in adults is unknown.Patients (age ≥ 15 years admitted with respiratory infections to two Guatemalan hospitals between November 2007 and March 2012 had urine and nasopharyngeal/oropharyngeal (NP/OP swabs collected; blood cultures and CXR were also performed at physician clinical discretion. 'Any bacterial infection' was defined as a positive urine pneumococcal antigen test, isolation of a bacterial pneumonia pathogen from blood culture, or detection of an atypical bacterial pathogen by polymerase chain reaction (PCR of nasopharyngeal/oropharyngeal (NP/OP specimens. 'Viral infection' was defined as detection of viral pathogens by PCR of NP/OP specimens. CXRs were interpreted according to the WHO protocol as having 'endpoint consolidation', 'other infiltrate', or 'normal' findings. We examined associations between bacterial and viral infections and endpoint consolidation.Urine antigen and/or blood culture results were available for 721 patients with CXR interpretations; of these, 385 (53% had endpoint consolidation and 253 (35% had other infiltrate.

    This study describes the prevalence of reported history of traumatic brain injury (TBI) and its association with reports of current substance use, cigarette smoking, and psychological distress among Canadian adults in a population sample. A cross-sectional sample of 1999 Ontario adults 18-93 years of age were surveyed by telephone in 2011 as part of the Center for Addiction and Mental Health's ongoing representative survey of adult mental health and substance use in Ontario, Canada. Loss of consciousness for at least 5 min or at least one overnight hospitalization resulting from symptoms associated with the TBI injury represented minimum criteria for TBI. An estimated 16.8% (95% confidence interval, 14.8, 19.0) of adults reported a TBI in their lifetime. Men had higher prevalence of TBI than women. Adults who reported a history of TBI had higher odds of reported past-year daily smoking (adjusted odds ratio [AOR] = 2.15), using cannabis (AOR = 2.80) and nonmedical opioids (AOR = 2.90), as well as screened significantly for recent elevated psychological distress (AOR = 1.97) in the past few weeks, compared to adults without a history of TBI. Co-occurrence of a history of TBI with current elevated psychological distress and substance use warrants vigilance among medical practitioners to assess the possibility of a history of TBI during reviews of the history leading to the occurrence of these conditions.

    After having experienced more than 2,000 cases of adult living donor liver transplantation (LDLT), we established the concepts of right liver graft standardization. Right liver graft standardization intends to provide hemodynamics-based and regeneration-compliant reconstruction of vascular inflow and outflow. Right liver graft standardization consists of the following components: Right hepatic vein reconstruction includes a combination of caudal-side deep incision and patch venoplasty of the graft right hepatic vein to remove the acute angle between the graft right hepatic vein and the inferior vena cava; middle hepatic vein reconstruction includes interposition of a uniform-shaped conduit with large-sized homologous or prosthetic grafts; if the inferior right hepatic vein is present, its reconstruction includes funneling and unification venoplasty for multiple short hepatic veins; if donor portal vein anomaly is present, its reconstruction includes conjoined unification venoplasty for two or more portal vein orifices. This video clip that shows the surgical technique from bench to reperfusion was a case presentation of adult LDLT using a modified right liver graft from the patient's son. Our intention behind proposing the concept of right liver graft standardization is that it can be universally applicable and may guarantee nearly the same outcomes regardless of the surgeon's experience. We believe that this reconstruction model would be primarily applied to a majority of adult LDLT cases.

    2016-08-01

    An increased prevalence of cystic fibrosis (CF) related complications such as impaired bone health and diabetes has accompanied increased survival of patients with CF. This review was conducted to determine the extent to which adults with CF are meeting current nutrition recommendations for micronutrients in association with CF-related complications management. Although dietary intake and nutritional status in CF has improved significantly in recent decades, micronutrient status seems to have diverged. While vitamin A and E intakes appear adequate, frequent vitamin D and K deficiency/insufficiency and compromised bone health in CF, occurs despite supplementation. Although deficiency of water-soluble vitamins and minerals is uncommon, ongoing surveillance will enhance overall health outcomes, particularly in cases of CF-related liver disease and deteriorated lung function and bone health. Salt and fluid status in CF may also need attention due to diminished thirst sensation and voluntary rehydration. Further investigation in micronutrient status optimisation in CF will inform the development of more effective and targeted nutrition therapies to enable integration of more refined recommendations for micronutrient intakes in CF based on individual needs and disease progression.

  16. The use of social media by adults with acquired conditions who use AAC: current gaps and considerations in research.

    2017-03-01

    The global growth and development of social media has had a positive impact on many individuals who use augmentative and alternative communication (AAC), who use it to communicate and connect with others. Research evidence into the use of social media by adults with acquired conditions who use AAC is limited. These individuals are a heterogeneous population, who can present with a range of linguistic, cognitive and physical needs, some of which progress rapidly, making accessing social media a challenge. These issues warrant research focusing on developing interventions to support the use of social media and the impact of these interventions. For individuals with acquired conditions who have previously used social media and for those who are new to the experience, social media can offer a vital connection to friends, family and health professionals. This paper examines current gaps in knowledge in this area in the field of AAC and proposes potential methodologies for future research. These include combining qualitative and quantitative methodologies (e.g., analysis of online interactions and observational data) that would be useful tools for data collection in an under-researched field.

    The number of adults with congenital heart disease (CHD) has increased markedly over the past few decades as a result of astounding successes in pediatric cardiac care. Nevertheless, it is now well understood that CHD is not cured but palliated, such that life-long expert care is required to optimize outcomes. All countries in the world that experience improved survival in CHD must face new challenges inherent to the emergence of a growing and aging CHD population with changing needs and medical and psychosocial issues. Founded in 1992, the International Society for Adult Congenital Heart Disease (ISACHD) is the leading global organization of professionals dedicated to pursuing excellence in the care of adults with CHD worldwide. Recognizing the unique and varied issues involved in caring for adults with CHD, ISACHD established a task force to assess the current status of care for adults with CHD across the globe, highlight major challenges and priorities, and provide future direction. The writing committee consisted of experts from North America, South America, Europe, South Asia, East Asia, and Oceania. The committee was divided into subgroups to review key aspects of adult CHD (ACHD) care. Regional representatives were tasked with investigating and reporting on relevant local issues as accurately as possible, within the constraints of available data. The resulting ISACHD position statement addresses changing patterns of worldwide epidemiology, models of care and organization of care, education and training, and the global research landscape in ACHD.

    Full Text Available Vaccination is one of the greatest achievements in public health of the 20th century. However, the success of vaccine uptake and adherence to immunization guidelines seen in pediatric populations has not been observed among adult Canadians. As a result of the disparity in susceptibility to vaccine-preventable disease, there has been an increasing shift of vaccine-preventable childhood diseases into adult populations. Accordingly, morbidity and mortality due to vaccine-preventable illnesses now occur disproportionately in adults. All Canadians, irrespective of age, should have immunity to measles, mumps, rubella, tetanus, diphtheria, pertussis and varicella. All adult Canadians with significant medical comorbidities or those older than 65 years of age should receive the pneumococcal polysaccharide vaccine and yearly trivalent inactivate influenza vaccines. The present review summarizes the burden of illness of these vaccine-preventable diseases in the Canadian adult population and reviews the current immunization recommendations. Vaccination of all Canadians to these common agents remains a vital tool to decrease individual morbidity and mortality and reduce the overall burden of preventable disease in Canada.

    Full Text Available The investigation of bootstrap current formation in ITER is carried out using BALDUR integrated predictive modelingcode. The combination of Mixed B/gB anomalous transport model and NLCASS module together with the pedestal model isused in BALDUR code to simulate the time evolution of temperature, density, and plasma current profiles. It was found inthe simulations that without the presence of ITB, a minimal fraction of bootstrap current (as well as low fusion performancewas achieved. The enhancement due to ITB depends sensitively on the strength of toroidal velocity. A sensitivity study wasalso carried out to optimize the bootstrap current fraction and plasma performance. It was found that the bootstrap currentfraction slightly improved; while the plasma performance greatly improved with increasing of NBI power or pedestal temperature.On the other hand, higher impurity concentration resulted in a significant degradation of fusion performance, buta smaller degradation in bootstrap current.

    AIM: To compare the value of endoscopic retrograde cholangiography (ERC) and standard T2-weighted magnetic resonance cholangiography (MRC) in the evaluation process as adult-to-adult right lobe living donor liver transplantation (LDLTx) demands a successful outcome, and exact knowledge of the biliary tree is implicated to avoid biliary complications,postoperatively.METHODS: After starting the LDLTx program, 18 liver transplant candidates were selected for LDLTx by a stepwise evaluation process. ERC and standard T2-weighted MRC were performed to evaluate the biliary system of the donor liver. The anatomical findings of ERC and MRC mapping were compared usingthe Ohkubo classification.RESULTS: ERC allowed mapping of the whole biliary system in 15/15 (100%) cases, including 14/15 (93.3%)with biliary variants while routine MRC was only accurate in 2/13 (15.4%) cases. MRC was limited in depicting the biliary system proximal of the hepatic bifurcation.Postoperative biliary complications occurred in 2 donors and 8 recipients. Biliary complications were associated with Ohkubo type C, E or G in 6/8 recipients, and 2/3recipients with biliary leak received a graft with multiple (≥2) bile ducts.CONCLUSION: Pretransplant ERC is safe and superior over standard MRC for detection of biliary variations that occur with a high frequency. However, precise knowledge of biliary variants did not reduce the incidence of postoperative biliary complications.

    2015-01-01

    This study compared sit to stand (STS) performance between older adults in a nine-week training program focusing on core stability exercises to enhance balance and postural control (EB) versus standard balance (SB) exercises. Repetitions in 30 s (STSreps) and kinematic performance (vertical and horizontal momentum, and margin of stability) were measured pre and postintervention in 23 older adults with at least one fall risk factor. Although both groups combined improved STSreps (P = .001) and vertical momentum (.008), a significant between-group difference was observed for completers only (MANCOVA of posttest group differences, with pretest scores as covariates; P = .04). EB demonstrated a greater but nonsignificant improvement in vertical momentum (P = .095). In conclusion, core stability training added to SB did not result in STS reps improvement. Compliance may modify these results and future larger sample studies should evaluate the impact of core stability training on STS biomechanics.

    Although active gaming is popular and can increase energy expenditure in young adults, its efficacy as a prescriptive exercise tool is not well understood. This study aimed to: (a) compare the activity intensities experienced by young adults while playing active tennis gaming with conventional sedentary gaming, tennis game-play, and current activity recommendations for health; and (b) identify changes in activity intensities across playing time. After habitualization, 10 active young adults (age: 20.2 ± 0.4 years; stature: 1.74 ± 0.03 m; body mass: 67.7 ± 3.3 kg) completed 3 experimental trials (sedentary gaming, active tennis gaming, and tennis game-play) on separate days in a randomized order. Heart rate (HR) and metabolic equivalents (METs) were averaged across 5 minutes and 10 minutes intervals, and the entire 20 minutes bout within each condition. Active gaming produced greater intensities across 5-10, 10-15, and 15-20 minutes time intervals compared with sedentary gaming (p Tennis game-play elicited greater HR (67 ± 5% HR(max)) and METs (5.0 ± 0.2) responses than both sedentary (40 ± 2% HR(max), 1.1 ± 0.1 METs) and active gaming (45 ± 2% HR(max), 1.4 ± 0.1 METs) (p tennis game-play produced activity intensities meeting current recommendations for health benefit. Lower HR intensities were reached across 0-5 minutes than during later time intervals during active gaming (6%) and tennis game-play (9%) (p tennis game-play and insufficient to contribute toward promoting and maintaining good health in young adults. These data suggest that active tennis gaming should not be recommended by exercise professionals as a substitute for actual sports participation in young adults.

    Corsi's block-tapping task and WAIS-R were administered to two Italian samples of 200 normal older adults (aged 65-74 years and 75-100 years). Corsi's reliabilities and standardization data are shown. Additionally, Corsi's location in the factor space of cognitive abilities represented by the 11 WAIS-R subtests is presented. Corsi's test seems to be a reliable one for older Italians. It seems also to be a measure of general intelligence in those 65-74 years of age and a measure of the Freedom from Distractibility factor in subjects 75 years and older.

    We investigated whether stimulating the cerebellum and primary motor cortex (M1) using transcranial direct current stimulation (tDCS) could affect postural control in young and older adults. tDCS was employed using a double-blind, sham-controlled design, in which young (aged 18-35) and older adults (aged 65+) were assessed over three sessions, one for each stimulatory condition-M1, cerebellar and sham. The effect of tDCS on postural control was assessed using a sway-referencing paradigm, which induced platform rotations in proportion to the participant's body sway, thus assessing sensory reweighting processes. Task difficulty was manipulated so that young adults experienced a support surface that was twice as compliant as that of older adults, in order to minimise baseline age differences in postural sway. Effects of tDCS on postural control were assessed during, immediately after and 30 minutes after tDCS. Additionally, the effect of tDCS on corticospinal excitability was measured by evaluating motor evoked potentials using transcranial magnetic stimulation immediately after and 30 minutes after tDCS. Minimal effects of tDCS on postural control were found in the eyes open condition only, and this was dependent on the measure assessed and age group. For young adults, stimulation had only offline effects, as cerebellar stimulation showed higher mean power frequency (MPF) of sway 30 minutes after stimulation. For older adults, both stimulation conditions delayed the increase in sway amplitude witnessed between blocks one and two until stimulation was no longer active. In conclusion, despite tDCS' growing popularity, we would caution researchers to consider carefully the type of measures assessed and the groups targeted in tDCS studies of postural control.

    We analyzed data from the Global Adult Tobacco Survey (GATS) from 21 countries to categorize smokers by stages of cessation and highlight interventions that could be tailored to each stage. GATS is a nationally representative household survey that measures tobacco use and other key indicators by using a standardized protocol. The distribution of smokers into precontemplation, contemplation, and preparation stages varied by country. Using the stages of change model, each country can design and implement effective interventions suitable to its cultural, social, and economic situations to help smokers advance successfully through the stages of cessation.

    The goal was to assess sex differences in career indecision's association with different levels of self-reported psychological adjustment and with different remembrances of maternal and paternal acceptance and behavioral control in childhood. 126 participants responded to the Career Decision Scale, the Adult version of the Parental Acceptance-Rejection/Control Questionnaire, and the Adult version of the Personality Assessment Questionnaire. Results showed that career indecision among women but not men was significantly correlated with remembered maternal and paternal acceptance in childhood, as well as with self-reported psychological adjustment and age. Only women's self-reported psychological adjustment made a unique contribution to variance in reported career indecision. No predictor variables were significantly associated with career indecision among men.

  2. Are the current attempts at standardization of antiphospholipid antibodies still useful? Emerging technologies signal a shift in direction.

    The pathogenic role of antiphospholipid antibodies (aPL) has been widely established over past years in several experimental models and clinical studies. Accordingly, the detection of aPL by immunoassays (anticardiolipin antibodies; anti-beta2 glycoprotein I antibodies) has become a routine practice in the clinical workup of patients with systemic autoimmune diseases. aPL are mostly assayed using commercial ELISA kits, whose performance has not been found to be sufficiently concordant among the different manufacturers. In the past years, collaborative groups have spent considerable effort to reach some form of standardization but this process is still ongoing. Such lack of standardization has recently become even more crucial, as manufacturers have had to face an increasing demand for fully automated tests for aPL, like those test systems that have been developed for other autoantibodies (e.g., antinuclear antibodies, anti-ENA antibodies). We therefore report our recent experience with two newly developed automated methods for anticardiolipin antibodies testing. In particular, we discuss the results obtained using routine samples, as we believe that these better reflect the "real-life" situation in which those automated methods will operate. We also mention other emerging technologies in the field of aPL detection.

    Platelet volume indices (PVI) are associated with hematological and non-hematological diseases, notably cardiovascular and cerebrovascular diseases. The establishment of PVI reference intervals (RIs) are essential to evaluate whether these indices are useful in clinical practice. Healthy-associated RIs have not yet been established for the Brazilian population. Here, we determined RIs of PVI for a health adult population, participants of the Brazilian Longitudinal Study of Adult Health ELSA-Brasil. A total of 580 individuals out of an initial sample of 3115 subjects constituted the healthy reference sample. To be part of the study, individuals had to fulfill the following criteria: blood count within 2 hours of collection, no use of continuous medication, self-rated health as good or very good, no reported diagnosis of diabetes and/or arterial hypertension, not smoking, lack of metabolic syndrome, body mass index (BMI) Brasil reported herein may contribute to future efforts aiming to evaluate whether PVI values are associated with clinical conditions in the Brazilian population.

Fourteen participants performed a standardized and semi-standardized protocol including seven daily life activity types, while having their EE measured by indirect calorimetry. Simultaneously, physical activity was quantified by an ActivPAL3, two ActiGraph GT3X+’s and an Actiheart. EE was estimated by the standard ActivPAL3 software (ActivPAL, ActiGraph GT3X+ (ActiGraph and Actiheart (Actiheart, and by a combination of activity type recognition via Acti4 software and activity counts per minute (CPM of either a hip- or thigh-worn ActiGraph GT3X+ (AGhip + Acti4 and AGthigh + Acti4. At group level, estimated physical activities EE by Actiheart (MSE = 2.05 and AGthigh + Acti4 (MSE = 0.25 were not significantly different from measured EE by indirect calorimetry, while significantly underestimated by ActiGraph, ActivPAL and AGhip + Acti4. AGthigh + Acti4 and Actiheart explained 77% and 45%, of the individual variations in measured physical activity EE by indirect calorimetry, respectively. This study concludes that combining accelerometer data from a thigh-worn ActiGraph GT3X+ with activity type recognition improved the accuracy of activity specific EE estimation against indirect calorimetry in semi-standardized settings compared to previously validated methods using CPM only.

    2012-12-01

    The educational system for medical technologists (MTs) has gradually shifted from a three-year technical school system to a four-year university system. It is worthwhile for MTs to advance to a graduate school, in order to improve their routine-work skills, performances, and also to advance their own research as well as to learn how to direct younger MTs. Recently, MTs who advance to the graduate school as adult graduate students are increasing. In this article, the current states and future aspects of the graduate school of Iwate Medical University are reported. In our Department of Central Clinical Laboratory in Iwate Medical University Hospital, three of my colleagues have completed the master's course of the graduate school as adult graduate students, and three are currently attending the school. Nevertheless, none of them has advanced to the doctor's course yet. The primary reason why they do not advance is the heavy burden on any adult graduate students physically, mentally, and financially to study in the graduate school and carry out routine duties at the same time. Thus, in order to encourage MTs to go or to graduate school education, it is important to arrange systems which will enable MTs to advance to the graduate school as adult graduate students. I believe there are three key elements to make this possible. Firstly, prepare easier access to curriculums for MTs to study special fields and learn special skills. Secondly, arrange an increase in the salary scheme depending on the degree attained from the graduate school. Thirdly, provide financial support for graduate school expenses. In conclusion, it is expected that a large number of MTs will advance to the graduate school if these changes for a better educational environment are made.

    As mobile data capture tools for patient-reported outcomes proliferate in clinical research, a key dimension of measure performance is sensitivity to change. This study compared performance of patient-reported measures of mindfulness, depression, and anxiety symptoms using traditional paper-and-pencil forms versus real-time, ambulatory measurement of symptoms via ecological momentary assessment (EMA). Sixty-seven emotionally distressed older adults completed paper-and-pencil measures of mindfulness, depression, and anxiety along with two weeks of identical items reported during ambulatory monitoring via EMA before and after participation in a randomized trial of Mindfulness-Based Stress Reduction (MBSR) or a health education intervention. We calculated effect sizes for these measures across both measurement approaches and estimated the Number-Needed-to-Treat (NNT) in both measurement conditions. Study outcomes greatly differed depending on which measurement method was used. When EMA was used to measure clinical symptoms, older adults who participated in the MBSR intervention had significantly higher mindfulness and significantly lower depression and anxiety than participants in the health education intervention at post-treatment. However, these significant changes in symptoms were not found when outcomes were measured with paper-and-pencil measures. The NNT for mindfulness and depression measures administered through EMA were approximately 25-50% lower than NNTs derived from paper-and-pencil administration. Sensitivity to change in anxiety was similar across administration modes. In conclusion, EMA measures of depression and mindfulness substantially outperformed paper-and-pencil measures with the same items. The additional resources associated with EMA in clinical trials would seem to be offset by its greater sensitivity to detect change in key outcome variables.

  10. Inflammation-induced changes in BKCa currents in cutaneous dorsal root ganglion neurons from the adult rat

    Full Text Available Abstract Background Inflammation-induced sensitization of primary afferents is associated with a decrease in K+ current. However, the type of K+ current and basis for the decrease varies as a function of target of innervation. Because glabrous skin of the rat hindpaw is used often to assess changes in nociception in models of persistent pain, the purpose of the present study was to determine the type and extent to which K+ currents contribute to the inflammation-induced sensitization of cutaneous afferents. Acutely dissociated retrogradely labeled cutaneous dorsal root ganglion neurons from naïve and inflamed (3 days post complete Freund’s adjuvant injection rats were studied with whole cell and perforated patch techniques. Results Inflammation-induced sensitization of small diameter cutaneous neurons was associated with an increase in action potential duration and rate of decay of the afterhyperpolarization. However, no changes in voltage-gated K+ currents were detected. In contrast, Ca2+ modulated iberiotoxin sensitive and paxilline sensitive K+ (BKCa currents were significantly smaller in small diameter IB4+ neurons. This decrease in current was not associated with a detectable change in total protein levels of the BKCa channel α or β subunits. Single cell PCR analysis revealed a significant change in the pattern of expression of α subunit splice variants and β subunits that were consistent, at least in part, with inflammation-induced changes in the biophysical properties of BKCa currents in cutaneous neurons. Conclusions Results of this study provide additional support for the conclusion that it may be possible, if not necessary to selectively treat pain arising from specific body regions. Because a decrease in BKCa current appears to contribute to the inflammation-induced sensitization of cutaneous afferents, BKCa channel openers may be effective for the treatment of inflammatory pain.

    The National Institute of Standards and Technology (NIST) has maintained scales for reflectance and transmittance over several decades. The scales are primarily intended for regular transmittance, mirrors, and solid surface scattering diffusers. The rapidly growing area of optical medical imaging needs a scale for volume scattering of diffuse materials that are used to mimic the optical properties of tissue. Such materials are used as phantoms to evaluate and validate instruments under development intended for clinical use. To address this need, a double-integrating sphere based instrument has been installed to measure the optical properties of tissue-mimicking phantoms. The basic system and methods have been described in previous papers. An important attribute in establishing a viable calibration service is the estimation of measurement uncertainties. The use of custom models and comparisons with other established scales enabled uncertainty measurements. Here, we describe the continuation of those efforts to advance the understanding of the uncertainties through two independent measurements: the bidirectional reflectance distribution function and the bidirectional transmittance distribution function of a commercially available solid biomedical phantom. A Monte Carlo-based model is used and the resulting optical properties are compared to the values provided by the phantom manufacturer.

    Diabetes mellitus is a highly prevalent multisystemic disorder with numerous potential complications and substantial socioeconomic consequences. In many cases, the patient history, physical examination and laboratory tests are not sufficient for a comprehensive evaluation of complicating disorders. Imaging modalities, such as sonography, computed tomography (CT) and magnetic resonance imaging (MRI) are of major significance in the evaluation of complicating disorders of diabetes according to current guidelines. Examples include assessment of coronary artery disease, peripheral artery disease, stroke and diabetic foot syndrome. Technical developments allow a substantial reduction in radiation dose and scan time in CT and MRI, respectively and could therefore justify a broader application in this patient population. In the future CT and MRI could also be used for the early detection of diabetic complications. Furthermore, they could also be used for risk stratification, e.g. measurement of hepatic fat content and evaluation of atherosclerosis in whole body MRI. Prior to widespread application of advanced imaging techniques in this patient population, improved outcomes with respect to survival, quality of life and cost-effectiveness need to be demonstrated. Diagnostic imaging modalities for the evaluation of the syndrome complex of diabetic disorders should be used according to the current guidelines but the use is predicted to increase given the high potential in this population.

    In 1984, a wild type 3 poliovirus (PV3/FIN84) spread all over Finland causing nine cases of paralytic poliomyelitis and one case of aseptic meningitis. The outbreak was ended in 1985 with an intensive vaccination campaign. By limited sequence comparison with previously isolated PV3 strains, closest relatives of PV3/FIN84 were found among strains circulating in the Mediterranean region. Now we wanted to reanalyse the relationships using approaches currently exploited in poliovirus surveillance. Cell lysates of 22 strains isolated during the outbreak and stored frozen were subjected to RT-PCR amplification in three genomic regions without prior subculture. Sequences of the entire VP1 coding region, 150 nucleotides in the VP1-2A junction, most of the 5' non-coding region, partial sequences of the 3D RNA polymerase coding region and partial 3' non-coding region were compared within the outbreak and with sequences available in data banks. In addition, complete nucleotide sequences were obtained for 2 strains isolated from two different cases of disease during the outbreak. The results confirmed the previously described wide intraepidemic variation of the strains, including amino acid substitutions in antigenic sites, as well as the likely Mediterranean region origin of the strains. Simplot and bootscanning analyses of the complete genomes indicated complicated evolutionary history of the non-capsid coding regions of the genome suggesting several recombinations with different HEV-C viruses in the past.

    2014-01-01

    Full Text Available The ubiquitin-proteasome system is the major intracellular molecular machinery for protein degradation and maintenance of protein homeostasis in most human cells. As ubiquitin-proteasome system plays a critical role in the regulation of the immune system, it might also influence the development and progression of multiple sclerosis (MS. Both ex vivo analyses and animal models suggest that activity and composition of ubiquitin-proteasome system are altered in MS. Proteasome isoforms endowed of immunosubunits may affect the functionality of different cell types such as CD8+ and CD4+ T cells and B cells as well as neurons during MS development. Furthermore, the study of proteasome-related biomarkers, such as proteasome antibodies and circulating proteasomes, may represent a field of interest in MS. Proteasome inhibitors are already used as treatment for cancer and the recent development of inhibitors selective for immunoproteasome subunits may soon represent novel therapeutic approaches to the different forms of MS. In this review we describe the current knowledge on the potential role of proteasomes in MS and discuss the pro et contra of possible therapies for MS targeting proteasome isoforms.

    Skoog, Gerald

    Efforts to eliminate or neutralize the coverage of evolution in high school biology textbooks in the United States have persisted with varying degrees of intensity and success since the 1920s. In particular, the coverage of human evolution has been impacted by these efforts. Evidence of the success of these efforts can be chronicled by the emphasis given to human evolution in secondary biology textbooks historically and in the current state science standards. Prior to the 1960s, biology textbooks provided little emphasis to human evolution. In the 1970s and early 1980s textbooks reduced the coverage of human evolution. However, in the 1990s the coverage became quite comprehensive again. In 2004, the state science frameworks of only three states had standards concerned with human evolution.

    2009-10-01

    Stem cell-based cell therapy has emerged as a potentially therapeutic option for patients with acute myocardial infarction (AMI) and heart failure. With the completion of a number of trials using bone marrow (BM)-derived adult stem cells, critical examination of the overall clinical benefits, limitations and potential side effects of this revolutionary treatment will pave the way for future clinical research. At present, clinical trials have been conducted almost exclusively using BM stem cells. The primary endpoints of these trials are mainly safety and feasibility, with secondary endpoints in the efficacy of post-myocardial infarction (MI) cardiac repair. Intervention with BM-derived cells was mainly carried out by endogenously-mobilised BM cells with granulocyte-colony stimulating factor, and more frequently, by intracoronary infusion or direct intramyocardial injection of autologous BM cells. While these studies have been proven safe and feasible without notable side effects, mixed outcomes in terms of clinical benefits have been reported. The major clinical benefits observed are improved cardiac contractile function and suppressed left ventricular negative remodelling, including reduced infarct size and improved cardiac perfusion of infarct zone. Moderate and transient clinical benefits have been mostly observed in studies with intracoronary infusion or direct intramyocardial injection of BM cells. These effects are widely considered to be indirect effects of implanted cells in association with paracrine factors, cell fusion, passive ventricular remodelling, or the responses of endogenous cardiac stem cells. In contrast, evidence of cardiac regeneration characterised by differentiation of implanted stem cells into cardiomyocytes and other cardiac cell lineages, is weak or lacking. To elucidate a clear risk-benefit of this exciting therapy, future studies on the mechanisms of cardiac cell therapy will need to focus on confirming the ideal cell types in relation

    In an integrative review of the literature covering the period 2004-2016, the author presents a current picture of the situation of people who are deaf or hard of hearing (DHH) relative to employment and careers-particularly the barriers, facilitators, and stress levels experienced by working DHH adults. First, an overview is provided of findings from recent reports on employment outcomes for people who are DHH. Second, the author reviews the literature on employment and workplace barriers, facilitators, and accommodations for people who are DHH, and relates findings about DHH people's workplace-related stress and fatigue levels and the associated issues of job demand, job control, and social support in the workplace. The article concludes with a discussion of the implications of these findings, in particular the ways in which barriers to full participation of DHH people in the labor market can be addressed.

    Full Text Available Abstract Background Research suggests that ACEs have a long-term impact on the behavioral, emotional, and cognitive development of children. These disruptions can lead to adoption of unhealthy coping behaviors throughout the lifespan. The present study sought to examine psychological distress as a potential mediator of sex-specific associations between adverse childhood experiences (ACEs and adult smoking. Method Data from 7,210 Kaiser-Permanente members in San Diego California collected between April and October 1997 were used. Results Among women, psychological distress mediated a significant portion of the association between ACEs and smoking (21% for emotional abuse, 16% for physical abuse, 15% for physical neglect, 10% for parental separation or divorce. Among men, the associations between ACEs and smoking were not significant. Conclusions These findings suggest that for women, current smoking cessation strategies may benefit from understanding the potential role of childhood trauma.

    This study investigated whether transcranial direct current stimulation (tDCS) on dorsolateral prefrontal cortex (DLPFC) isolated or combined with aerobic exercise influenced the desire to eat, hunger, and satiety in overweight subjects. Nine volunteers underwent anodal or sham tDCS (2 mA; 20 min) over DLPFC and isocaloric exercise bouts (70%VO(2)R; ~200 kcal). The appetite sensations were evaluated by visual analogue scales at four moments: I - Baseline; II - After tDCS; III - Post-Exercise and IV - 30-min Post-Exercise. The tDCS on left DLPFC decreased the desire to eat at baseline (tDCS -26% vs. -14% Sham). The tDCS associated with exercise had greater suppressing effect in desire to eat compared to either tDCS or exercise alone (tDCS -39% vs. -27% Sham). Moreover, the tDCS associated with exercise decreased hunger (tDCS -48% vs. 36% Sham) and increased satiety (tDCS 28% vs. 7% Sham) immediately after exercise. The post-exercise 30-min recovery elicited an overall increase in appetite. However the increase in desire to eat and hunger after recovery was lower after tDCS (29% and 13%, respectively) compared to sham stimulation (77% and 113%, respectively). These findings in overweight subjects indicate that the combination of tDCS over DLPFC and aerobic exercise induced greater decrease in appetite sensations compared to anodal tDCS or exercise alone.

    Full Text Available Abstract Background The variable-stiffness colonoscope (VSC appears to have advantages over the standard adult colonoscope (SAC, although data are conflicting. To provide a comprehensive up-to-date review, we conducted a meta-analysis to compare the efficacies of the VSC and SAC. Methods Electronic databases, including PubMed, EMBASE, the Cochrane library and the Science Citation Index, were searched to retrieve relevant trials. In addition, meeting abstracts and the reference lists of retrieved articles were reviewed for further relevant studies. Results Eight randomized controlled trials (RCTs, enrolling a total of 2033 patients, were included in the meta-analysis. There was no significant heterogeneity among these studies. The cecal intubation rate was higher with the use of VSC (RR = 1.03, 95% CI 1.01 to 1.06, 8 RCTs. The VSC was also associated with fewer position changes made during colonoscopy. Time to cecal intubation was similar with VSC and SAC (WMD −0.54, 95% CI −1.40 to 0.32 but shorter in subgroup analysis with the use of VSC (WMD = −1.36, 95% CI −2.29 to −0.43. Sedation dose used with the two types of instruments showed no evidence of differences either. For all trials, only patients were blinded because of the nature of the interventions. Conclusion Use of the VSC significantly improved the cecal intubation rate and reduced ancillary maneuvers made during the procedure. Cecal intubation time was similar for the two colonoscope types over all trials, whereas a shortened time with the use of the adult VSC was seen in subgroup analysis.

  8. On the evolution of the standard genetic code: vestiges of critical scale invariance from the RNA world in current prokaryote genomes.

    Directory of Open Access Journals (Sweden)

    Marco V José

    Full Text Available Herein two genetic codes from which the primeval RNA code could have originated the standard genetic code (SGC are derived. One of them, called extended RNA code type I, consists of all codons of the type RNY (purine-any base-pyrimidine plus codons obtained by considering the RNA code but in the second (NYR type and third (YRN type reading frames. The extended RNA code type II, comprises all codons of the type RNY plus codons that arise from transversions of the RNA code in the first (YNY type and third (RNR nucleotide bases. In order to test if putative nucleotide sequences in the RNA World and in both extended RNA codes, share the same scaling and statistical properties to those encountered in current prokaryotes, we used the genomes of four Eubacteria and three Archaeas. For each prokaryote, we obtained their respective genomes obeying the RNA code or the extended RNA codes types I and II. In each case, we estimated the scaling properties of triplet sequences via a renormalization group approach, and we calculated the frequency distributions of distances for each codon. Remarkably, the scaling properties of the distance series of some codons from the RNA code and most codons from both extended RNA codes turned out to be identical or very close to the scaling properties of codons of the SGC. To test for the robustness of these results, we show, via computer simulation experiments, that random mutations of current genomes, at the rates of 10(-10 per site per year during three billions of years, were not enough for destroying the observed patterns. Therefore, we conclude that most current prokaryotes may still contain relics of the primeval RNA World and that both extended RNA codes may well represent two plausible evolutionary paths between the RNA code and the current SGC.

    The existing accounting standards conform to the trend of internationalization, changing from the rule-oriented mode to principle-oriented mode, which no longer carries out provisions for specific operations of the business and only gives accounting principles. This change not only expands the space of judgment of accounting personnel, but also imposes higher requirements of accounting personnel professional knowledge and skills. This paper analyzes the current standards of accounting professional judgment ability, in order to improve the account-ing professional judgment.%现有会计准则顺应了国际化趋势,由原有的规则导向模式转变为原则导向模式,不再对业务的具体操作进行细节性的规定,而仅给出会计核算的原则性要求。这一转变虽然扩大了会计人员的职业判断空间,但也对会计人员的专业知识和技能提出了更高的要求。本文对现有准则下会计人员职业判断能力进行分析,以期对会计职业判断的提高起到一定的推动作用。

    This study compared the long-term effectiveness of three physical activity counseling strategies among sedentary older adults: a 1-contact referral (REFER), a 1-contact individualized walking program (WALK), and multiple-contact, individually tailored, and need-supportive coaching based on the self-determination theory (COACH). Participants (n = 442) completed measurements before (pretest), immediately after (posttest), and 1 yr after (follow-up test) a 10-wk intervention. Linear mixed models demonstrated significant time-by-condition interaction effects from pre- to posttest. More specifically, WALK and COACH yielded larger increases in daily steps and self-reported physical activity than REFER. Similarly, self-reported physical activity increased more from pre- to follow-up test in WALK and COACH compared with REFER. Autonomous motivation mediated the effect of perceived need-support on physical activity, irrespective of counseling strategy. These results demonstrate the long-term effectiveness of both a 1-contact individualized walking program and a more time-consuming, need-supportive coaching, especially in comparison with a standard referral to local opportunities.

    Full Text Available Background: Thalassemia major patients with repeated blood transfusion have high prevalence of endocrinopathies due to iron overload. Materials and Methods: We examined the adrenocortical function in 23 thalassemic patients (10 children and 13 young adults aged 8-26 years. Serum cortisol and dehydroepiandrosterone sulfate (DHEA-S concentrations were determined in each subject before blood transfusion both in basal condition and after low dose (LD (1 μg, followed by standard dose (SD (250 μg, respectively with synthetic corticotrophin beta 1-24 ACTH (Synacthen, Ciba. Normal controls were a group of 13 age- and sex-matched normal subjects. Results: Using a peak total cortisol cutoff level of 550 nmol/L and increments of 200 μg above basal cortisol, adrenal insufficiency (AI was demonstrated in 8 patients (34.7% after the LD ACTH and in 2 patients (8.7% after SD cosyntropin (ACTH test, but none of the controls. Using a peak total cortisol cutoff level of 420 nmol/L and increments of 200 μg above basal cortisol, AI was demonstrated in 5 patients (21.7% after the LD ACTH and in 2 patients after SD ACTH test (8.7%, but none of controls. All patients with biochemical AI were asymptomatic with normal serum sodium and potassium concentrations and had no history suggestive of adrenal pathology. The peak cortisol concentrations in thalassemic patients with impaired adrenal function both after 1 μg and 250 μg cosyntropin (294 ± 51 nmol/L and 307 ± 58.6 were significantly lower than those with patients with normal (454 ± 79.7 nmol/L and 546.1 ± 92.2 nmol/L, respectively and controls (460.2 ± 133.4 nmol/L and 554.3 ± 165.8 nmol/L, respectively. Adolescents and young adults, but not children with thalassaemia, had significantly lower peak cortisol concentration after SD ACTH versus controls. Peak cortisol response to LD ACTH was correlated significantly with peak cortisol response to SD in all patients (r = 0.83, P < 0.0001. In adolescents and

    2016-01-01

    Transcranial direct current stimulation (tDCS) targeting the prefrontal cortex reduces the size and speed of standing postural sway in younger adults, particularly when performing a cognitive dual task. Here, we hypothesized that tDCS would alter the complex dynamics of postural sway as quantified by multiscale entropy (MSE). Twenty healthy older adults completed two study visits. Center-of-pressure (COP) fluctuations were recorded during single-task (i.e., quiet standing) and dual-task (i.e., standing while performing serial subtractions) conditions, both before and after a 20-min session of real or sham tDCS. MSE was used to estimate COP complexity within each condition. The percentage change in complexity from single- to dual-task conditions (i.e., dual-task cost) was also calculated. Before tDCS, COP complexity was lower (p = 0.04) in the dual-task condition as compared to the single-task condition. Neither real nor sham tDCS altered complexity in the single-task condition. As compared to sham tDCS, real tDCS increased complexity in the dual-task condition (p = 0.02) and induced a trend toward improved serial subtraction performance (p = 0.09). Moreover, those subjects with lower dual-task COP complexity at baseline exhibited greater percentage increases in complexity following real tDCS (R = −0.39, p = 0.05). Real tDCS also reduced the dual-task cost to complexity (p = 0.02), while sham stimulation had no effect. A single session of tDCS targeting the prefrontal cortex increased standing postural sway complexity with concurrent non-postural cognitive task. This form of noninvasive brain stimulation may be a safe strategy to acutely improve postural control by enhancing the system's capacity to adapt to stressors. PMID:25963755

    Full Text Available In high income nations, traumatic life experiences such as childhood sexual abuse are much more common in people living with HIV/AIDS (PLWHA than the general population, and trauma is associated with worse current health and functioning. Virtually no data exist on the prevalence or consequences of trauma for PLWHA in low income nations.We recruited four cohorts of Tanzanian patients in established medical care for HIV infection (n = 228, individuals newly testing positive for HIV (n = 267, individuals testing negative for HIV at the same sites (n = 182, and a random sample of community-dwelling adults (n = 249. We assessed lifetime prevalence of traumatic experiences, recent stressful life events, and current mental health and health-related physical functioning. Those with established HIV infection reported a greater number of childhood and lifetime traumatic experiences (2.1 and 3.0 respectively than the community cohort (1.8 and 2.3. Those with established HIV infection reported greater post-traumatic stress disorder (PTSD symptomatology and worse current health-related physical functioning. Each additional lifetime traumatic experience was associated with increased PTSD symptomatology and worse functioning.This study is the first to our knowledge in an HIV population from a low income nation to report the prevalence of a range of potentially traumatic life experiences compared to a matched community sample and to show that trauma history is associated with poorer health-related physical functioning. Our findings underscore the importance of considering psychosocial characteristics when planning to meet the health needs of PLWHA in low income countries.

    2016-12-22

    In the Swedish Building Energy, Technical Status and Indoor environment study, a total of 1160 adults from 605 single-family houses answered a questionnaire on respiratory health. Building inspectors investigated the homes and measured temperature, air humidity, air exchange rate, and wood moisture content (in attic and crawl space). Moisture load was calculated as the difference between indoor and outdoor absolute humidity. Totally, 7.3% were smokers, 8.7% had doctor' diagnosed asthma, 11.2% current wheeze, and 9.5% current asthma symptoms. Totally, 50.3% had respiratory infections and 26.0% rhinitis. The mean air exchange rate was 0.36/h, and the mean moisture load 1.70 g/m(3) . Damp foundation (OR=1.79, 95% CI 1.16-2.78) was positively associated while floor constructions with crawl space (OR=0.49, 95% CI 0.29-0.84) was negatively associated with wheeze. Concrete slabs with overlying insulation (OR=2.21, 95% CI 1.24-3.92) and brick façade (OR=1.71, 95% CI 1.07-2.73) were associated with rhinitis. Moisture load was associated with respiratory infections (OR=1.21 per 1 g/m(3) , 95% CI 1.04-1.40) and rhinitis (OR=1.36 per 1 g/m(3) , 95% CI 1.02-1.83). Air exchange rate was associated with current asthma symptoms (OR=0.85 per 0.1/h, 95% CI 0.73-0.99). Living in homes with damp foundation, concrete slabs with overlying insulation, brick façade, low ventilation flow, and high moisture load are risk factors for asthma, rhinitis, and respiratory infections.

    The impact of chronic ethanol treatment, sufficient to induce tolerance and physical dependence, on GABAA receptor function was studied in acutely isolated neurons from the medial septum/nucleus diagonal band (MS/nDB) of adult rats using whole cell, patch-clamp recordings. In ethanol-naive Controls, GABA (0.3-300 microM) induced concentration-dependent increases in Cl- current with a threshold of 0.3-1 microM, a mean maximal current of 7645 +/- 2148 pA at 100-300 microM, an EC50 of 11.3 +/- 1.3 microM and a slope of 1.53 +/- 0.07. GABA-activated currents in neurons from animals receiving two weeks of ethanol liquid diet treatment did not differ significantly on any of these measures. The rate of GABAA receptor desensitization (t1/2 = 6.49 +/- 1.19 s) estimated as the time required for loss of 50% of peak current during sustained application of 10 microM GABA, as well as the residual steady state current remaining following complete desensitization for controls was unchanged by chronic ethanol. The impact of chronic ethanol treatment on the GABAA receptor modulation by lanthanum and zinc which act as positive and negative allosteric modulators, respectively, was also evaluated. Test pulses of 3 microM GABA in control neurons showed maximal potentiation by 141 +/- 30% at approximately 1000 microM lanthanum with an EC50 of 107 +/- 34 microM and a slope of approximately 1. Lanthanum potentiation remained the same following chronic ethanol treatment. Initial estimates based on fitted concentration response curves suggested that maximal inhibition of 3 microM GABA responses by zinc at the level of 70.2 +/- 8.5% in control cells was significantly increased by chronic ethanol treatment to 95.3 +/- 2.5%, although the IC50 of 60.2 +/- 25 microM was not changed. However, this difference was not supported by direct tests of maximal 3-10 mM zinc concentrations. These results suggest that chronic ethanol treatment, sufficient to induce tolerance and physical dependence, probably

    Background Commercial Web-based weight-loss programs are becoming more popular and increasingly refined through the addition of enhanced features, yet few randomized controlled trials (RCTs) have independently and rigorously evaluated the efficacy of these commercial programs or additional features. Objective To determine whether overweight and obese adults randomized to an online weight-loss program with additional support features (enhanced) experienced a greater reduction in body mass index (BMI) and increased usage of program features after 12 and 24 weeks compared to those randomized to a standard online version (basic). Methods An assessor-blinded RCT comparing 301 adults (male: n=125, 41.5%; mean age: 41.9 years, SD 10.2; mean BMI: 32.2 kg/m2, SD 3.9) who were recruited and enrolled offline, and randomly allocated to basic or enhanced versions of a commercially available Web-based weight-loss program for 24 weeks. Results Retention at 24 weeks was greater in the enhanced group versus the basic group (basic 68.5%, enhanced 81.0%; P=.01). In the intention-to-treat analysis of covariance with imputation using last observation carried forward, after 24 weeks both intervention groups had reductions in key outcomes with no difference between groups: BMI (basic mean –1.1 kg/m2, SD 1.5; enhanced mean –1.3 kg/m2, SD 2.0; P=.29), weight (basic mean –3.3 kg, SD 4.7; enhanced mean –4.0 kg, SD 6.2; P=.27), waist circumference (basic mean –3.1 cm, SD 4.6; enhanced mean –4.0 cm, SD 6.2; P=.15), and waist-to-height ratio (basic mean –0.02, SD 0.03; enhanced mean –0.02, SD 0.04, P=.21). The enhanced group logged in more often at both 12 and 24 weeks, respectively (enhanced 12-week mean 34.1, SD 28.1 and 24-week mean 43.1, SD 34.0 vs basic 12-week mean 24.6, SD 25.5 and 24-week mean 31.8, SD 33.9; P=.002). Conclusions The addition of personalized e-feedback in the enhanced program provided limited additional benefits compared to a standard commercial Web

    Full Text Available Abstract Background Hawthorn extract has been used for cardiovascular diseases for centuries. Recent trials have demonstrated its efficacy for the treatment of heart failure, and the results of several small trials suggest it may lower blood pressure. However, there is little published evidence to guide its dosing. The blood pressure lowering effect of hawthorn has been linked to nitric oxide-mediated vasodilation. The aim of this study was to investigate the relationship between hawthorn extract dose and brachial artery flow mediated dilation (FMD, an indirect measure of nitric oxide release. Methods We used a four-period cross-over design to evaluate brachial artery FMD in response to placebo or hawthorn extract (standardized to 50 mg oligomeric procyanidin per 250 mg extract. Randomly sequenced doses of hawthorn extract (1000 mg, 1500 mg, and 2500 mg and placebo were assigned to each participant. Doses were taken twice daily for 3 1/2 days followed by FMD and a 4-day washout before proceeding to the next dosing period. Results Twenty-one prehypertensive or mildly hypertensive adults completed the study. There was no evidence of a dose-response effect for our main outcome (FMD percent or any of our secondary outcomes (absolute change in brachial artery diameter and blood pressure. Most participants indicated that if given evidence that hawthorn could lower their blood pressure, they would be likely to use it either in conjunction with or instead of lifestyle modification or anti-hypertensive medications. Conclusion We found no evidence of a dose-response effect of hawthorn extract on FMD. If hawthorn has a blood pressure lowering effect, it is likely to be mediated via an NO-independent mechanism. Trial Registration This trial has been registered with ClinicalTrials.gov, a service of the U.S. National Institutes of Health: NCT01331486.

By differentiating according to age groups (15–24 and 25–49 years, this study aimed to help family planning program planners better tailor interventions to improve utilization of modern contraception.Methods: A household survey was used to collect data from 1,545 women of reproductive age living in Luanda Province, Angola. Data on sociodemographic characteristics, reproductive behavior and intentions, contraceptive knowledge and use, and attitudes and beliefs regarding contraception and abortion were collected. The analyses were stratified based on age: 15–24 years (youth and 25–49 years (adult. Multivariate logistic regression models were built for each age group, adding different subsets of variables in groups to see how relationships changed across the models.Results: Common factors associated with modern contraceptive use among all ages include education level, perceived contraceptive accessibility, contraceptive knowledge, communication with partner about family planning in last year, and self-efficacy. Exposure to family planning information in the media in the last few months, perceived partner approval of family planning, and marital status were all positively associated with current modern contraceptive use among women aged 15–24 years. Meanwhile, receiving information about family planning from a pharmacy in the last year was uniquely associated with current modern contraceptive use among women aged 25–49 years.Conclusion: Young women in

    2008-04-01

    As the longevity of all patients with cystic fibrosis (CF) continues to increase (median 2005 survival=36.8 years), more adult patients will be receiving their medical care from nonpediatric adult-care providers. Cystic fibrosis remains a fatal disease, with more than 80% of patients dying after the age of 18 years, and most deaths resulting from pulmonary disease. The changing epidemiology requires adult-care providers to become knowledgeable and competent in the clinical management of adults with CF. Physicians must understand the influence of specific genotype on phenotypic disease presentation and severity, the pathogenic factors determining lung disease onset and progression, the impact of comorbid disease factors such as CF-related diabetes and malnutrition upon lung disease severity, and the currently approved or standard accepted therapies used for chronic management of CF lung disease. This knowledge is critical to help alleviate morbidity and improve mortality for the rapidly expanding population of adults with CF.

    The Dual-frequency Precipitation Radar (DPR) on the Global Precipitation Measurement (GPM) core satellite was developed by Japan Aerospace Exploration Agency (JAXA) and National Institute of Information and Communications Technology (NICT). The objective of the GPM mission is to observe global precipitation more frequently and accurately. The GPM core satellite is a joint product of National Aeronautics and Space Administration (NASA), JAXA and NICT. NASA developed the satellite bus and the GPM Microwave Imager (GMI), and JAXA and NICT developed the DPR. The inclination of the GPM core satellite is 65 degrees, and the nominal flight altitude is 407 km. The non-sunsynchronous circular orbit is necessary for measuring the diurnal change of rainfall. The DPR consists of two radars, which are Ku-band precipitation radar (KuPR) and Ka-band precipitation radar (KaPR). GPM core observatory was successfully launched by H2A launch vehicle on Feb. 28, 2014. DPR keeps its performances on orbit after launch. DPR products were released to the public on Sep. 2, 2014. JAXA is continuing DPR trend monitoring, calibration and validation operations to confirm that DPR keeps its function and performance on orbit. JAXA have started to provide new version (Version 4) of GPM standard products on March 3, 2016. Various improvements of the DPR algorithm were implemented in the Version 4 product. Moreover, the latent heat product based on the Spectral Latent Heating (SLH) algorithm is available since Version 4 product. Current orbital operation status of the GPM/DPR and highlights of the Version 4 product are reported.

  13. Radiotherapy of high-grade gliomas:current standards and new concepts, innovations in imaging and radiotherapy, and new therapeutic approaches

    2014-01-01

    The current standards in radiotherapy of high-grade gliomas (HGG) are based on anatomic imaging techniques, usually computed tomography (CT) scanning and magnetic resonance imaging (MRI). The guidelines vary depending on whether the HGG is a histological grade 3 anaplastic glioma (AG) or a grade 4 glioblastoma multiforme (GBM). For AG, T2-weighted MRI sequences plus the region of contrast enhancement in T1 are considered for the delineation of the gross tumor volume (GTV), and an isotropic expansion of 15 to 20 mm is recommended for the clinical target volume (CTV). For GBM, the Radiation Therapy Oncology Group favors a two-step technique, with an initial phase (CTV1) including any T2 hyperintensity area (edema) plus a 20 mm margin treated with up to 46 Gy in 23 fractions, followed by a reduction in CTV2 to the contrast enhancement region in T1 with an additional 25 mm margin. The European Organisation of Research and Treatment of Cancer recommends a single-phase technique with a unique GTV, which comprises the T1 contrast enhancement region plus a margin of 20 to 30 mm. A total dose of 60 Gy in 30 fractions is usual y delivered for GBM, and a dose of 59.4 Gy in 33 fractions is typical y given for AG. As more than 85% of HGGs recur in field, dose-escalation studies have shown that 70 to 75 Gy can be delivered in 6 weeks with relevant toxicities developing in60 Gy. Trials delivering a SIB into a biological GTV showed the feasibility of this treatment, but the final results, in terms of clinical benefits for HGG patients, are stil pending. Many issues have been identified: the variety of MRI and PET machines (and amino-acid tracers), the heterogeneity of the protocols used for image acquisition and post-treatment, the geometric distortion and the unreliable algorithms for co-registration of brain anatomy with functional maps, and the semi-quiescent but highly invasive HGG cells. These issues could be solved by the homogenization of the protocols and software

    Measurement of the catalytic activity concentration of enzymes has been standardized using a traceability chain, consisting a reference measurement system for enzyme catalytic activity and reference standard-JSCC enzyme. The Japan Medical Association (JMA) has provided an external quality assessment (EQA) survey program for clinical laboratory testing. More than 3,100 clinical laboratories participated in 2008. The EQA program indicated that standardization of the measurement of the catalytic activity concentration of enzymes has been completed for AST, ALT, LD, ALP, gammaGT, and CK in more than 90% laboratories, and for Amy and ChE in nearly 80% of laboratories. Because such a large survey program must use artificial specimens, a matrix effect cannot be avoided, especially in dry chemistry. However, the bias produced by a matrix effect usually has a predictable tendency: it can be corrected. Next, after standardization of the measurement of the catalytic activity concentration of enzymes, we should develop and use common reference intervals. On completing the standardization, we can make standard medical decisions using reference measurement systems and rules.

Compared with the old standard MT 312, there were the following differences: circulation composite loading project was added for testing comprehensive performance of the support, and the number of time was 2 - 3 times of the original one; contraction performance test project was added to assess the support ability to withstand roof sinking; strength test projects such as horizontal and concentrated loading were added also. These changes and improvements raised higher requirement for the structural strength, endurance and safety performance of the hydraulic support. The new standard was almost in line with international standards. The issuance of the standard made the hydraulic support standard system more perfect, and would play an important role in enhancing the design, manufacturing and test level of the hydraulic support.

    Older adults are vulnerable to hospital-associated complications such as falls, pressure ulcers, functional decline, and delirium, which can contribute to prolonged hospital stay, readmission, and nursing home placement. These vulnerabilities are exacerbated when the hospital's practices, services, and physical environment are not sufficiently mindful of the complex, multidimensional needs of frail individuals. Several frameworks have emerged to help hospitals examine how organization-wide processes can be customized to avoid these complications. This article describes the application of one such framework-the Senior-Friendly Hospital (SFH) framework adopted in Ontario, Canada-which comprises five interrelated domains: organizational support, processes of care, emotional and behavioral environment, ethics in clinical care and research, and physical environment. This framework provided the blueprint for a self-assessment of all 155 adult hospitals across the province of Ontario. The system-wide analysis identified practice gaps and promising practices within each domain of the SFH framework. Taken together, these results informed 12 recommendations to support hospitals at all stages of development in becoming friendly to older adults. Priorities for system-wide action were identified, encouraging hospitals to implement or further develop their processes to better address hospital-acquired delirium and functional decline. These recommendations led to collaborative action across the province, including the development of an online toolkit and the identification of accountability indicators to support hospitals in quality improvement focusing on senior-friendly care.

  7. Perceived Comfort and Blinding Efficacy in Randomised Sham-Controlled Transcranial Direct Current Stimulation (tDCS Trials at 2 mA in Young and Older Healthy Adults.

    Directory of Open Access Journals (Sweden)

    Denise Wallace

    Full Text Available tDCS studies typically find that: lowest levels of comfort occur at stimulation-onset; young adult participants experience less comfort than older participants; and participants' blinding seems effective at low current strengths. At 2 mA conflicting results have been reported, questioning the effectiveness of blinding in sham-controlled paradigms using higher current strengths. Investigator blinding is rarely reported.Using a protocol with 30 min of 2 mA stimulation we sought to: (a investigate the level of perceived comfort in young and older adults, ranging in age from 19 to 29 years and 63 to 76 years, respectively; (b test investigator and participant blinding; (c assess comfort over a longer stimulation duration; (d add to the literature on protocols using 2 mA current strength.A two-session experiment was conducted where sham and active stimulation were administered to the frontal cortex at the F8/FP1 sites in a within-subjects manner. Levels of perceived comfort were measured, using a visual analogue scale, at the start and end of stimulation in young and older adults. Post-stimulation, participants and investigators judged whether or not active stimulation was used.Comfort scores were lower at stimulation onset in both age groups. Older adults reported: (i more comfort than young participants overall; (ii comparable levels of comfort in sham and active stimulation; (iii significantly more comfort than the young participants during active stimulation. Stimulation mode was correctly identified above chance in the second of the two sessions; 65% of all participants correctly identified the stimulation mode, resulting in a statistical trend. Similarly, the experimenter correctly identified stimulation mode significantly above chance, with 62% of all investigator judgements correct across 120 judgements.Using 2 mA current strength over 30 minutes, tDCS stimulation comfort is lower at stimulation onset in young and older adults and, overall

  8. Standardization of calibration of clinic dosemeters using electric currents and charges; Padronizacao da calibracao de dosimetros clinicos utilizando cargas e correntes eletricas

    Energy Technology Data Exchange (ETDEWEB)

    Peres, Marcos Antonio de Lima

    1999-09-15

    Clinical dosimeters used in radiotherapy are calibrated in Latin American countries, including Brazil, as a complete 'system, i.e., ionization chamber and electrometer together. Some countries, as European ones, and USA calibrate them by component, i.e., ionisation chamber apart from electrometer. This method is more advantageous than the previous one, since it makes possible the automation of the calibration process, allowing the acquisition of data related to the chamber and the electrometer measurements independently, as well as the substitution of one of the components, in case of failure. This work proposes a method for standardisation of low intensity electric charge and currents in order to implement electric calibration of electrometers. This will make possible the implementation of a by components calibration technique, by components, of clinical dosimeters in Brazil. The results obtained with the calibration by components prove that the proposed method of standardisation of low electric charges and currents is viable. The difficulties found for the generation and measurement of low intensity electric charges and currents and the procedures adopted for the calibration by components are presented. Additionally, a current source was built to yield reference electric charges that will make possible the quality control clinical dosimeters. This source will also allow the user to identify the defective components of the dosimeters, through a simple verification test. (author)

    The theoretical risk of exceeding the Acceptable Daily Intake (ADI) for sulphites has mostly been examined on the basis of a worst-case scenario. In order to examine the real situation the determination of residue sulphite levels in ready-to-consume foods is required. The aim of this paper is to assess the actual sulphite content of diets obtained from a combination of realistic meals high in sulphite-containing foods. Food products available in Italy containing added sulphites were identified. Overall, 211 samples of foods and beverages (including 85 samples of wine) were collected. The determination of sulphite residues was carried out on the foods which were prepared according to normal domestic practice. It was shown that the diets obtained from these foods would lead to an intake of 23 mg/day in children and 50 mg/day in adults (both slightly above the ADI for respectively a 30 kg child and a 60 kg adult). Among all sulphite-containing foods, the highest contributors to the intake were dried fruit and wine, both ingested without further treatment. The analysis of specific consumption data confirmed the existence of a risk of exceeding the ADI related to sulphite residue levels in wine.

    How old one feels-one's subjective age-has been shown to predict important psychological and health outcomes. The current studies examined the effect of taking a standard memory test on older adults' subjective age. Study 1 showed that older adults felt older after taking a standard neuropsychological screening test and participating in a free-recall experiment than they felt at baseline. Study 2 showed that the effect was selective to older adults: Younger adults' subjective age was not affected by participating in the memory experiment. Study 3 showed that the subjective-aging effect was specific to memory, as taking a vocabulary test for a similar amount of time did not affect older adults' subjective age. Finally, Study 4 showed that simply expecting to take a memory test subjectively aged older adults. The results indicate that being in a memory-testing context affects older adults' self-perception by making them feel older.

    Adolescent and young adult (AYA) cancer patients under 40 should be made aware of their fertility risks and preservation options throughout their care. However, discussions on fertility preservation (FP) do not routinely occur. With a dearth of FP resources, oncology providers may lack knowledge around FP. Thus, informational needs can be unmet, leading to anxiety and distress in patients. Provision of pertinent and timely information can help patients cope better with their diagnosis. FP pamphlets were developed for men and women with cancer. A cross-sectional in-house survey, using convenience sampling, evaluated the pamphlets' effectiveness and measured ease of understanding, acceptability, and perceived utility. Patients and partners were also asked to provide recommendations and complete the Short Test of Functional Health Literacy in Adults (S-TOFHLA) measuring health literacy level. This helps determine if health literacy influences perception of pamphlet effectiveness. All participants (n = 56) reviewed both pamphlets. Fifty-four participants (96 %) found the pamphlet for men useful, while 29 participants (52 %) improved their male fertility knowledge. The pamphlet for women was useful for 52 participants (93 %) and improved knowledge in 35 (63 %) of them. Although the majority of participants had adequate health literacy (98 %), there was insufficient sample diversity to determine if health literacy influenced the pamphlet's effectiveness. Participants indicated preference in receiving verbal (73 %) and written (66 %) information over watching videos or in-class education. They recommended including fertility clinics, financial resources, and statistics in the brochures. These FP pamphlets were concluded as effective in supporting patients in making FP decisions.

    A randomised, double-blind, placebo-controlled, parallel group study assessed in healthy adults how daily consumption of the probiotic combination SYNBIO®, administered in probiotic-enriched foods or in a dietary supplement, affected bowel habits. Primary and secondary outcomes gave the overall assessment of bowel well-being, while a Psychological General Well-Being Index compiled by participants estimated the health-related quality of life as well as the gastrointestinal tolerance determined with the Gastrointestinal Symptom Rating Scale. Support Vector Machine models for classification problems were used to validate the total outcomes on bowel well-being. SYNBIO® consumption improved bowel habits of volunteers consuming the probiotic foods or capsules, while the same effects were not registered in the control groups. The recovery of probiotic bacteria from the faeces of a cohort of 100 subjects for each supplemented group showed the persistence of strains in the gastrointestinal tract.

    Purpose: To compare quality of survival in “standard-risk” medulloblastoma after hyperfractionated radiation therapy of the central nervous system with that after standard radiation therapy, combined with a chemotherapy regimen common to both treatment arms, in the PNET4 randomised controlled trial. Methods and Materials: Participants in the PNET4 trial and their parents/caregivers in 7 participating anonymized countries completed standardized questionnaires in their own language on executive function, health status, behavior, health-related quality of life, and medical, educational, employment, and social information. Pre- and postoperative neurologic status and serial heights and weights were also recorded. Results: Data were provided by 151 of 244 eligible survivors (62%) at a median age at assessment of 15.2 years and median interval from diagnosis of 5.8 years. Compared with standard radiation therapy, hyperfractionated radiation therapy was associated with lower (ie, better) z-scores for executive function in all participants (mean intergroup difference 0.48 SDs, 95% confidence interval 0.16-0.81, P=.004), but health status, behavioral difficulties, and health-related quality of life z-scores were similar in the 2 treatment arms. Data on hearing impairment were equivocal. Hyperfractionated radiation therapy was also associated with greater decrement in height z-scores (mean intergroup difference 0.43 SDs, 95% confidence interval 0.10-0.76, P=.011). Conclusions: Hyperfractionated radiation therapy was associated with better executive function and worse growth but without accompanying change in health status, behavior, or quality of life.

    Falls and fall related injuries become an emerging health problem among older adults. As a result a review of the recent evidences is needed to design a prevention strategy. The aim of this review was to determine the effect of square stepping exercise (SSE) for fall down injury among older adults compared with walking training or other exercises. An electronic database search for relevant randomized control trials published in English from 2005 to 2016 was conducted. Articles with outcome measures of functional reach, perceived health status, fear of fall were included. Quality of the included articles was rated using Physiotherapy Evidence Database (PEDro) scale and the pooled effect of SSE was obtained by Review Manager (RevMan5) software. Significant effect of SSE was detected over walking or no treatment to improve balance as well to prevent fear of fall and improve perceived health status. The results of this systematic review proposed that SSE significantly better than walking or no treatment to prevent fall, prevent fear of fall and improve perceived health status.

    This research was conducted to determine whether objective measures of muscle color, muscle pH, and(or) electrical impedance are useful in segregating palatable beef from unpalatable beef, and to determine whether the current USDA quality grading standards for beef carcasses could be revised to improve their effectiveness at distinguishing palatable from unpalatable beef. One hundred beef carcasses were selected from packing plants in Texas, Illinois, and Ohio to represent the full range of muscle color observed in the U.S. beef carcass population. Steaks from these 100 carcasses were used to determine shear force on eight cooked beef muscles and taste panel ratings on three cooked beef muscles. It was discovered that the darkest-colored 20 to 25% of the beef carcasses sampled were less palatable and considerably less consistent than the other 75 to 80% sampled. Marbling score, by itself, explained 12% of the variation in beef palatability; hump height, by itself, explained 8% of the variation in beef palatability; measures of muscle color or pH, by themselves, explained 15 to 23% of the variation in beef palatability. When combined together, marbling score, hump height, and some measure of muscle color or pH explained 36 to 46% of the variation in beef palatability. Alternative quality grading systems were proposed to improve the accuracy and precision of sorting carcasses into palatability groups. The two proposed grading systems decreased palatability variation by 29% and 39%, respectively, within the Choice grade and decreased palatability variation by 37% and 12%, respectively, within the Select grade, when compared with current USDA standards. The percentage of unpalatable Choice carcasses was reduced from 14% under the current USDA grading standards to 4% and 1%, respectively, for the two proposed systems. The percentage of unpalatable Select carcasses was reduced from 36% under the current USDA standards to 7% and 29%, respectively, for the proposed systems

    Full Text Available Abstract Background Reading problems are frequently reported by visually impaired persons. A closed-circuit television (CCTV can be helpful to maintain reading ability, however, it is difficult to learn how to use this device. In the Netherlands, an evidence-based rehabilitation program in the use of CCTVs was lacking. Therefore, a standard training protocol needed to be developed and tested in a randomized controlled trial (RCT to provide an evidence-based training program in the use of this device. Methods/Design To develop a standard training program, information was collected by studying literature, observing training in the use of CCTVs, discussing the content of the training program with professionals and organizing focus and discussion groups. The effectiveness of the program was evaluated in an RCT, to obtain an evidence-based training program. Dutch patients (n = 122 were randomized into a treatment group: normal instructions from the supplier combined with training in the use of CCTVs, or into a control group: instructions from the supplier only. The effect of the training program was evaluated in terms of: change in reading ability (reading speed and reading comprehension, patients' skills to operate the CCTV, perceived (vision-related quality of life and tasks performed in daily living. Discussion The development of the CCTV training protocol and the design of the RCT in the present study may serve as an example to obtain an evidence-based training program. The training program was adjusted to the needs and learning abilities of individual patients, however, for scientific reasons it might have been preferable to standardize the protocol further, in order to gain more comparable results.

    Objective: To evaluate brachial plexus MRI accuracy with surgical findings and clinical follow-up as reference standard in a large multicentre study. Materials and methods: The research was approved by the Institutional Review Boards, and all patients provided their written informed consent. A multicentre retrospective trial that included three centres was performed between March 2006 and April 2011. A total of 157 patients (men/women: 81/76; age range, 18–84 years) were evaluated: surgical findings and clinical follow-up of at least 12 months were used as the reference standard. MR imaging was performed with different equipment at 1.5 T and 3.0 T. The patient group was divided in five subgroups: mass lesion, traumatic injury, entrapment syndromes, post-treatment evaluation, and other. Sensitivity, specificity with 95% confidence intervals (CIs), positive predictive value (PPV), pre-test-probability (the prevalence), negative predictive value (NPV), pre- and post-test odds (OR), likelihood ratio for positive results (LH+), likelihood ratio for negative results (LH−), accuracy and post-test probability (post-P) were reported on a per-patient basis. Results: The overall sensitivity and specificity with 95% CIs were: 0.810/0.914; (0.697–0.904). Overall PPV, pre-test probability, NPV, LH+, LH−, and accuracy: 0.823, 0.331, 0.905, 9.432, 0.210, 0.878. Conclusions: The overall diagnostic accuracy of brachial plexus MRI calculated on a per-patient base is relatively high. The specificity of brachial plexus MRI in patients suspected of having a space-occupying mass is very high. The sensitivity is also high, but there are false-positive interpretations as well.

    Previous reports have shown that N-methyl-D-aspartate (NMDA) receptors are extensively involved in epilepsy genesis and recurrence.Recent studies have shown that synaptic and extrasynaptic NMDA receptors play different, or even opposing, roles in various signaling pathways, including synaptic plasticity and neuronal death.The present study analyzed changes in synaptic and extrasynaptic NMDA receptor-mediated currents during epilepsy onset.Mouse models of lithium chloride pilocarpine-induced epilepsy were established, and hippocampal slices were prepared at 24 hours after the onset of status epilepticus.Synaptic and extrasynaptic NMDA receptor-mediated excitatory post-synaptic currents (NMDA-EPSCs) were recorded in CA1 pyramidal neurons by whole-cell patch clamp technique.Results demonstrated no significant difference in rise and delay time of synaptic NMDA-EPSCs compared with normal neurons.Peak amplitude, area-to-peak ratio,and rising time of extrasynaptic NMDA-EPSCs remained unchanged, but decay of extrasynaptic NMDA-EPSCs was faster than that of normal neurons.These results suggest that extrasynaptic NMDA receptors play a role in epileptogenesis.

Intradermal (ID vaccination has been proposed as a cost-saving alternative method for administration of hepatitis B vaccine. However, the effectiveness of ID vaccination needs to be assessed in different ethnic groups. Methods: From September 2006 to March 2008, 185 healthy anti-HBc-negative medical and nursing students at Zahedan University of Medical Sciences who had no history of vaccination against HBV, smoking or hepatitis were evaluated. They were randomly categorized into two groups. In group I (n=91, low-dose (4 |mg recombinant hepatitis B vaccine (Euvax B, Korea was given by intradermal route. In group II (n=94, the standard dose (20 mg of the vaccine was administered intramuscularly at 0, 1, and 6 months. The groups were followed for a minimum of 7 months after the first vaccine dose and tested for anti-HBs titers by ELISA (Diasorin Bio Medica Kit, Saluugia, Italy.Results: Seroprotective anti-HBs titers (titer >10 mIU/mL were achieved in 79 (87% students in group I and in 90 (96% in group II (P=0.031. The difference was much pronounced when the two groups were compared for achieving an anti-HBs titer >300 mIU/mL (P<0.0001.Conclusions: Although ID administration of 4-mg recombinant hepatitis B vaccine is effective, this route is less effective with lower immune response than the IM vaccination.

  11. A 3.2-GHz fully integrated low-phase noise CMOS VCO with self-biasing current source for the IEEE 802.11a/hiperLAN WLAN standard

    A 3.3V, fully integrated 3.2-GHz voltage-controlled oscillator (VCO) is designed in a 0.18μm CMOS technology for the IEE 802.11a/HiperLAN WLAN standard for the UNII band from 5.15 to 5.35 GHz. The VCO is tunable between 2.85 GHz and 3.31 GHz. NMOS architecture with self-biasing current of the tank source is chosen. A startup circuit has been employed to avoid zero initial current. Current variation is lower than 1% for voltage supply variations of 10%. The use of a self-biasing current source in the tank provides a greater safety in the transconductance value and allows running along more extreme point operation The designed VCO displays a phase noise and output power of -98dBc/Hz (at 100 KHz offset frequency) and 0dBm respectively. This phase noise has been obtained with inductors of 2.2nH and quality factor of 12 at 3.2 GHz, and P-N junction varactors whose quality factor is estimated to exceed 40 at 3.2 GHz. These passive components have been fabricated, measured and modeled previously. The core of the VCO consumes 33mW DC power.

  15. Modern Biotechnology—Current Standards in Japan

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    @@In the past few years, a new technology, biotechnology, has come into practical use internationally. It is prospective that application of biotechnology in the field of food production may lead to improved food quality and productivity.   Modern biotechnology, through the use of recombinant DNA techniques, has been used for food production for some time now. Therefore, particular attention should be paid to the safety of foods and food additives produced by recombinant DNA techniques. For this reason, Japan set out the “Guideline for Safety Assessment of Foods and Food Additives Produced by Recombinant DNA Techniques” and “Guideline for Manufacturing Foods and Food Additives Produced by Recombinant DNA Techniques,” in 1991.

    Cumulative effects analysis (CEA) allows natural resource managers to understand the status of resources in historical context, learn from past management actions, and adapt future activities accordingly. U.S. federal agencies are required to complete CEA as part of environmental impact assessment under the National Environmental Policy Act (NEPA). Past research on CEA as part of NEPA has identified significant deficiencies in CEA practice, suggested methodologies for handling difficult aspects of CEA, and analyzed the rise in litigation over CEA in U.S. courts. This article provides a review of the literature and legal standards related to CEA as it is done under NEPA and then examines current practice on a U.S. National Forest, utilizing qualitative methods in order to provide a detailed understanding of current approaches to CEA. Research objectives were to understand current practice, investigate ongoing challenges, and identify impediments to improvement. Methods included a systematic review of a set of NEPA documents and semi-structured interviews with practitioners, scientists, and members of the public. Findings indicate that the primary challenges associated with CEA include: issues of both geographic and temporal scale of analysis, confusion over the purpose of the requirement, the lack of monitoring data, and problems coordinating and disseminating data. Improved monitoring strategies and programmatic analyses could support improved CEA practice.

    Full Text Available In South Africa, abacavir (ABC is currently recommended as part of first- and second-line antiretroviral therapy (ART for HIV-positive paediatric patients. Concerns about overprescribing of the drug, particularly to adults, led to an analysis of ABC use in public sector ART programmes. We investigated current prescription of the drug to adults and children accessing ART in 4 public sector programmes across Gauteng Province, South Africa. ABC was almost exclusively prescribed to children initiating ART and adults requiring regimen changes due to drug toxicities. Patterns of ABC use among HIV-positive paediatric patients followed national ART treatment guidelines on the application of the drug. Although ABC is commonly used in the private sector for adults, the current national ART treatment guidelines for adults and adolescents should include ABC as an alternative to standard first- or second-line ART.

    Traditional Chinese herbal Medicine (TCHM) has been gaining interest and acceptance world wide. TCHM provides on the one side promising perspective of scientific interest and on the other side possible health risks if TCHM drugs are not controlled with respect to quality standards or if practitioners for TCHM are not well trained. This paper outlines an introduction to the scientific aspects and potential risks of TCHM therapy followed by a brief, exploratory overview of the current status of TCHM regulations in certain Western countries like the USA, United Kingdom, Germany, Australia and in China as the Eastern origin country of TCHM. Legal foundations to establish quality and safety standards for TCHM crude drugs and ready-made formulas exist in some countries on a local basis but in practice are poorly enforced, where this products have no drug status. In addition practitioners treating patients with TCHM should be well versed in the pharmacology, side effects, and interactions of these substances with Western medicines and should be certified on a regular basis.

    电流互感器的暂态特性是影响继保装置正确动作、攸关系统安全稳定的关键因素之一,对入网的电流互感器开展暂态特性试验或检测具有重要意义。为准确掌握试验用标准信号的信息,提出了相应的参数估计方法。在噪声允许的范围内,求标准信号的正极大值。结合暂态发生的时间信息,截取出暂态时段内的各个正极大值,再利用对数变换将其转换为直线函数,使用最小二乘法拟合得到直线的截距与斜率,分别对应暂态电流的幅值及时间常数。仿真结果表明:当标准信号的采样频率为6.4 kHz并伴有20 dB高斯白噪声时,所提方法能精确估计出暂态发生时刻,对暂态电流时间常数的估计精度高于暂态电流幅值,暂态电流时间常数的估计范围为80∼210 ms。所得结论为开展电流互感器的暂态特性试验提供了参考依据。%Transient performance of the current transformer (CT) is one of key factors that relates to the security and stability of power grids and whether the protective relaying could be operated correctly, so it is of great significance for grid-connected CT to perform transient performance test or detection. To master the information of standard signals for the test, corresponding parameter estimation method is proposed to solve the positive maximum of standard signals within the allowed noise range. Combining with the time information when the transient process happens, positive maximums within the transient time period are captured, then they are transformed into linear function by logarithmic transformation, and then using least square fitting both intercept and slope of the linear function are obtained, which correspond to the amplitude and time constant of transient current respectively. Simulation results show that when the sampling frequency of the standard signal is 6.4 kHz accompanied with 20 dB of Gaussian white noise, using the

    2009-01-01

    Hypersexuality, also referred to in the literature as sexually inappropriate behavior and sexual disinhibition, involves persistent, uninhibited sexual behaviors directed at oneself or at others. For older adults, the literature generally attributes the behavior to biochemical or physiological changes that accompany cognitive impairment-specifically, dementia. Although less common than other behavioral issues, such as aggression and agitation, hypersexuality presents complex logistical and ethical problems for caregivers. This article reviews the current literature on hypersexual behavior. Assessment essentials as well as nonpharmacological and pharmacological treatment approaches are discussed, identifying the need for standardization as well as caregiver education and training.

    Full Text Available Recent asthma deaths were examined from yearly reports of the Ministry of Health, Labor and Welfare of Japan and from reports published by the Japan Asthma Death Investigation Committee on 811 deaths over the period 1992–2000. The rate and number of recent asthma deaths in Japan have been decreasing rapidly. Most asthma deaths were of patients aged 70–90 years and there has been a marked trend for increased asthma deaths in the elderly. As for the circumstances surrounding the deaths, sudden death, unstable sudden aggravation and intermittent aggravation were mainly noted. Respiratory infections, fatigue and stress were the major courses of fatal attacks contributing to deaths due to asthma. Many of the patients who died from asthma had been diagnosed as having as moderate to severe asthma and many had non-atopic asthma. There are some reports that suggest that the recent decrease in asthma deaths in Japan is correlated with the use of inhaled cortico- steroids.

    Nergård-Nilssen, Trude; Hulme, Charles

    2014-08-01

    This paper explores the nature of residual literacy and cognitive deficits in self-reported dyslexic Norwegian adults. The performance of 26 self-reported dyslexic adults was compared with that of a comparison group of 47 adults with no history of reading or spelling difficulties. Participants completed standardized and experimental measures tapping literacy skills, working memory, phonological awareness and rapid naming. Spelling problems were the most prominent marker of dyslexia in adults, followed by text reading fluency and nonword decoding. Working memory and phoneme awareness explained unique variance in spelling, whereas rapid automatized naming explained unique variance in reading fluency and nonword reading. The moderate to strong correlations between self-reported history, self-rating of current literacy skills and outcomes on literacy tests indicate that adults estimated their literacy skills fairly well. Results suggest that spelling impairments, more strongly than reading impairments, make adults perceive themselves as being dyslexic. A combination of three literacy and three cognitive tests predicted group membership with 90.4% accuracy. It appears that weaknesses in phoneme awareness, rapid automatized naming and working memory are strong and persistent correlates of literacy problems even in adults learning a relatively transparent orthography.

    Toullec, E

    2015-02-01

    Adult flatfoot is defined as a flattening of the medial arch of the foot in weight-bearing and lack of a propulsive gait. The 3 lesion levels are the talonavicular, tibiotarsal and midfoot joints. The subtalar joint is damaged by the consequent rotational defects. Clinical examination determines deformity and reducibility, and assesses any posterior tibialis muscle deficit, the posterior tibialis tendon and spring ligament being frequently subject to degenerative lesions. Radiographic examination in 3 incidences in weight-bearing is essential, to determine the principal level of deformity. Tendon (posterior tibialis tendon) and ligamentous lesions (spring ligament and interosseous ligament) are analyzed on MRI or ultrasound. In fixed deformities, CT explores for arthritic evolution or specific etiologies. 3D CT reconstruction can analyze bone and joint morphology and contribute to the planning of any osteotomy. Medical management associates insoles and physiotherapy. Acute painful flatfoot requires strict cast immobilization. Surgical treatment associates numerous combinations of procedures, currently under assessment for supple flatfoot: for the hindfoot: medial slide calcaneal osteotomy, calcaneal lengthening osteotomy, or arthroereisis; for the midfoot: arthrodesis on one or several rays, or first cuneiform or first metatarsal osteotomy; for the ankle: medial collateral ligament repair with tendon transfer. Fixed deformities require arthrodesis of one or several joint-lines in the hindfoot; for the ankle, total replacement after realignment of the foot, or tibiotalocalcaneal fusion or ankle and hindfoot fusion; and, for the midfoot, cuneonavicular or cuneometatarsal fusion. Tendinous procedures are often associated. Specific etiologies may need individualized procedures. In conclusion, adult flatfoot tends to be diagnosed and managed too late, with consequent impact on the ankle, the management of which is complex and poorly codified.

    2008-11-01

    Full Text Available Abstract Background Over the past ten years MRSA has become endemic in hospitals and is associated with increased healthcare costs. Critically ill patients are most at risk, in part because of the number of invasive therapies that they require in the intensive care unit (ICU. Washing with 5% tea tree oil (TTO has been shown to be effective in removing MRSA on the skin. However, to date, no trials have evaluated the potential of TTO body wash to prevent MRSA colonization or infection. In addition, detecting MRSA by usual culture methods is slow. A faster method using a PCR assay has been developed in the laboratory, but requires evaluation in a large number of patients. Methods/Design This study protocol describes the design of a multicentre, phase II/III prospective open-label randomized controlled clinical trial to evaluate whether a concentration of 5% TTO is effective in preventing MRSA colonization in comparison with a standard body wash (Johnsons Baby Softwash in the ICU. In addition we will evaluate the cost-effectiveness of TTO body wash and assess the effectiveness of the PCR assay in detecting MRSA in critically ill patients. On admission to intensive care, swabs from the nose and groin will be taken to screen for MRSA as per current practice. Patients will be randomly assigned to be washed with the standard body wash or TTO body wash. On discharge from the unit, swabs will be taken again to identify whether there is a difference in MRSA colonization between the two groups. Discussion If TTO body wash is found to be effective, widespread implementation of such a simple colonization prevention tool has the potential to impact on patient outcomes, healthcare resource use and patient confidence both nationally and internationally.

The traveler represented the American Society for Testing and Materials' Committee on Terminology, of which he is the Chair. The traveler's invited workshop emphasized terminology standardization requirements in databases of material properties as well as practical terminology standardizing methods. The congress included six workshops in addition to approximately 82 lectures and papers from terminologists, artificial intelligence practitioners, and subject specialists from 18 countries. There were approximately 292 registrants from 33 countries who participated in the congress. The congress topics were broad. Examples were the increasing use of International Standards Organization (ISO) Standards in legislated systems such as the USSR Automated Data Bank of Standardized Terminology, the enhanced Physics Training Program based on terminology standardization in Physics in the Chinese province of Inner Mongolia, and the technical concept dictionary being developed at the Japan Electronic Dictionary Research Institute, which is considered to be the key to advanced artificial intelligence applications. The more usual roles of terminology work in the areas of machine translation. indexing protocols, knowledge theory, and data transfer in several subject specialties were also addressed, along with numerous special language terminology areas.

    2013-01-01

    This is a review of electroweak precision physics with particular emphasis on low-energy precision measurements in the neutral current sector of the electroweak theory and includes future experimental prospects and the theoretical challenges one faces to interpret these observables. Within the minimal Standard Model they serve as determinations of the weak mixing angle which are competitive with and complementary to those obtained near the Z-resonance. In the context of new physics beyond the Standard Model these measurements are crucial to discriminate between models and to reduce the allowed parameter space within a given model. We illustrate this for the minimal supersymmetric Standard Model with or without R-parity.

  4. Incorporating protein transduction domains (PTD) within intracellular proteins associated with the 'stemness' phenotype. Novel use of such recombinant 'fusion' proteins to overcome current limitations of applying autologous adult stem cells in regenerative medicine?

    Science.gov (United States)

    Heng, Boon Chin; Cao, Tong

    2005-01-01

    Adult stem cells originating from post-natal tissues hold tremendous promise in regenerative medicine. Nevertheless, there are several deficiencies of adult stem cells that would limit their application in transplantation therapy, in particular their relative scarcity, restricted multi-potency and limited proliferative capacity in vitro. A possible approach to overcome these limitations would be to genetically modulate adult stem cells to strongly express genes that are closely associated with the 'stemness' phenotype. Overwhelming safety concerns would preclude the direct application of recombinant DNA technology in genetic modulation. Moreover, constitutive expression of 'stemness' genes would prevent adult stem cells from participating in tissue/organ regeneration upon transplantation. A novel alternative would be to incorporate protein transduction domains within intracellular proteins (i.e. transcription factors) that are associated with the 'stemness' phenotype. Such recombinant fusion proteins would then have the ability to translocate across the cell membrane and be internalized within the cytosol, thereby enabling them to exert a gene-modulatory effect on the cell, without any permanent genetic alteration. This would be particularly useful for maintaining the 'stemness' of adult stem cell populations during extensive ex vivo proliferation, to generate adequate cell numbers for transplantation therapy.

    Stebler, Shane

    2014-01-01

    The current system used to generate standard hazard reports is considered cumbersome and iterative. This study defines a structure for this system's process in a clear, algorithmic way so that standard hazard reports and basic hazard analysis may be completed using a centralized, web-based computer application. To accomplish this task, a test server is used to host a prototype of the tool during development. The prototype is configured to easily integrate into NASA's current server systems with minimal alteration. Additionally, the tool is easily updated and provides NASA with a system that may grow to accommodate future requirements and possibly, different applications. Results of this project's success are outlined in positive, subjective reviews complete by payload providers and NASA Safety and Mission Assurance personnel. Ideally, this prototype will increase interest in the concept of standard hazard automation and lead to the full-scale production of a user-ready application.

    De Venecia, Toni; Lu, Marvin; Figueredo, Vincent M

    2016-01-01

    Hypertension remains a major societal problem affecting 76 million, or approximately one third, of US adults. While more prevalent in the older population, an increasing incidence in the younger population, including athletes, is being observed. Active individuals, like the young and athletes, are viewed as free of diseases such as hypertension. However, the increased prevalence of traditional risk factors in the young, including obesity, diabetes mellitus, and renal disease, increase the risk of developing hypertension in younger adults. Psychosocial factors may also be contributing factors to the increasing incidence of hypertension in the younger population. Increased left ventricular wall thickness and mass are increasingly found in young adults on routine echocardiograms and predict future cardiovascular events. This increasing incidence of hypertension in the young calls for early surveillance and prompt treatment to prevent future cardiac events. In this review we present the current epidemiological data, potential mechanisms, clinical implications, and treatment of hypertension in young patients and athletes.

  11. Signal Processing Strategies for Cochlear Implants Using Current Steering

    Directory of Open Access Journals (Sweden)

    Waldo Nogueira

    2009-01-01

    Full Text Available In contemporary cochlear implant systems, the audio signal is decomposed into different frequency bands, each assigned to one electrode. Thus, pitch perception is limited by the number of physical electrodes implanted into the cochlea and by the wide bandwidth assigned to each electrode. The Harmony HiResolution bionic ear (Advanced Bionics LLC, Valencia, CA, USA has the capability of creating virtual spectral channels through simultaneous delivery of current to pairs of adjacent electrodes. By steering the locus of stimulation to sites between the electrodes, additional pitch percepts can be generated. Two new sound processing strategies based on current steering have been designed, SpecRes and SineEx. In a chronic trial, speech intelligibility, pitch perception, and subjective appreciation of sound were compared between the two current steering strategies and standard HiRes strategy in 9 adult Harmony users. There was considerable variability in benefit, and the mean results show similar performance with all three strategies.

    1996-09-01

    The current that flows between the electrical test equipment and the nuclear explosive must be limited to safe levels during electrical tests conducted on nuclear explosives at the DOE Pantex facility. The safest way to limit the current is to use batteries that can provide only acceptably low current into a short circuit; unfortunately this is not always possible. When it is not possible, current limiters, along with other design features, are used to limit the current. Three types of current limiters, the fuse blower, the resistor limiter, and the MOSFET-pass-transistor limiters, are used extensively in Pantex test equipment. Detailed failure mode and effects analyses were conducted on these limiters. Two other types of limiters were also analyzed. It was found that there is no best type of limiter that should be used in all applications. The fuse blower has advantages when many circuits must be monitored, a low insertion voltage drop is important, and size and weight must be kept low. However, this limiter has many failure modes that can lead to the loss of over current protection. The resistor limiter is simple and inexpensive, but is normally usable only on circuits for which the nominal current is less than a few tens of milliamperes. The MOSFET limiter can be used on high current circuits, but it has a number of single point failure modes that can lead to a loss of protective action. Because bad component placement or poor wire routing can defeat any limiter, placement and routing must be designed carefully and documented thoroughly.

    Two general families of new quantum-deformed current algebras are proposed and identified both as infinite Hopf family of algebras, a structure which enables one to define "tensor products" of these algebras. The standard quantum affine algebras turn out to be a very special case of the two algebra families, in which case the infinite Hopf family structure degenerates into a standard Hopf algebra. The relationship between the two algebraic families as well as thefr various special examples are discussed, and the free boson representation is also considered.

    Full Text Available Sleep quality decreases with aging and thus sleep complaints are prevalent in older adults, particularly for those with cognitive impairment and dementia. For older adults, emerging evidence suggests poor sleep quality increases risk of developing cognitive impairment and dementia. Given the aging population – and the impending economic burden associated with increasing numbers of dementia patients – there is pressing need to improve sleep quality among older adults. As such, research efforts have increased focus on investigating the association between age-related sleep changes and cognitive decline in older adults. Sleep quality is a complex construct to evaluate empirically, and yet the Pittsburg Sleep Quality Index (PSQI is commonly used in studies as their only measure of sleep quality. Furthermore, the PSQI may not be the best sleep quality measure for older adults, due to its reliance on the cognitive capacity to reflect on the past month. Further study is needed to determine the PSQI’s validity among older adults. Thus, the current study examined sleep quality for 78 community dwelling adults 55+ to determine the PSQI’s predictive validity for objective sleep quality (as measured by actigraphy. We compared two subjective measures of sleep quality – the PSQI and Consensus Sleep Diary (CSD – with actigraphy (MotionWatch 8; camntech. Our results suggest perceived sleep quality is quite different from objective reality, at least for adults 55+. Importantly, we show this difference is unrelated to age, gender, education, or cognitive status (assessed using standard screens. Previous studies have shown the PSQI to be a valuable tool for assessing subjective sleep quality; however, our findings indicate for older adults the PSQI should not be used as a substitute for actigraphy, or vice versa. Hence, we conclude best practice is to include both subjective and objective measures when examining sleep quality in older adults (i.e., the

  5. The Costs and Benefits of Employing an Adult with Autism Spectrum Disorder: A Systematic Review.

    Directory of Open Access Journals (Sweden)

    Andrew Jacob

    Full Text Available Despite an ambition from adults with Autism Spectrum Disorder (ASD to be employed, there are limited opportunities for competitive employment for this group. Employment is not only an entitlement enjoyed by others in society, but employing adults with ASD also has economic benefits by decreasing lost productivity and resource costs for this group. Few studies have explored the cost-benefit ratio for employing adults with ASD and even fewer have taken the viewpoint of the employer, particularly applying this situation to ASD. Until such study occurs, employers may continue to be reluctant to employ adults from this group.This review aimed to examine the costs, benefits and the cost-benefit ratio of employing adults with ASD, from a societal perspective and from the perspective of employers.Eight databases were searched for scientific studies within defined inclusion criteria. These databases included CINAHL Plus, Cochrane Library, Emerald, Ovid Medline, ProQuest, PsycINFO, Scopus and Web of Science.Enhancing the opportunities for adults with ASD to join the workforce is beneficial from a societal perspective, not only from an inclusiveness viewpoint, but also from a strict economic standpoint. Providing supported employment services for adults with ASD does not only cut the cost compared with providing standard care, it also results in better outcomes for adults with ASD. Despite the fact that ASD was the most expensive group to provide vocational rehabilitation services for, adults with ASD have a strong chance of becoming employed once appropriate measures are in place. Hence, rehabilitation services could be considered as a worthwhile investment. The current systematic review uncovered the fact that very few studies have examined the benefits, the costs and the cost-benefit ratio of employing an adult with ASD from the perspective of employers indicating a need for this topic to be further explored.

  6. Reading Comprehension Strategies for Adult Literacy Outcomes.

    Although research on improving child literacy is converging, no such body of research exists for adult literacy. Yet the need is no less significant. This study extends the knowledge garnered with younger populations by determining the reading comprehension strategies most important to adults' success on adult literacy outcome measures and aligning them with previously researched interventions. According to an analysis of key adult literacy outcome measures (i.e., competency-based, standardized tests of literacy commonly accepted as reasonable proxies for the global construct of adult literacy: Comprehensive Adult Student Assessment System [CASAS], General Educational Development [GED], and National Assessment of Educational Progress [NAEP]), adults should benefit from strategies that teach looking for clues in or generating questions about a text. Additionally, adults need to learn how to summarize and draw inferences in order to address higher-level literacy demands. Adult learners also need a metacognitive strategy to self-regulate reading behavior (e.g., choose a strategy to use, evaluate its effectiveness, and abandon and choose another strategy if necessary.) Furthermore, when using a competency-based standardized test, adult learners need to be coincidentally taught test-taking skills to reduce the test-related task demands and produce a better index of a learner's reading comprehension skills.

  8. Comparison of a standardized procedure with current laboratory practices for the detection of lupus anticoagulant in France. Working Group on Hemostasis of the Société Française de Biologie Clinique.

    Science.gov (United States)

    1993-11-15

    A multicenter study involving 13 laboratories was designed to compare a common procedure for screening lupus anticoagulants (LA) to the different practices currently in use in these laboratories. The common procedure combined 3 phospholipid-dependent assays, including mixing studies and a phospholipid neutralizing test. Due to the heterogeneity of LA expression, an abnormal result in at least one of the tests was sufficient to classify a sample as positive for LA. Consecutive samples referred for LA diagnosis were evaluated in parallel by each participant and the data found using the common procedure were analyzed independently according to mutually agreed cut-offs and criteria for sample classification. Within a period of 3 months, 535 samples were included, of which 147 were judged LA positive, 29 undetermined and 359 negative by the respective laboratories using their current practice. When using the common procedure, 149 plasmas were said to be positive, 38 undetermined and 348 negative. Absolute concordance occurred for 81% of the specimen population and absolute discordance (positive versus negative) for 7%. The level of agreement between the common procedure and the current practices, assessed by kappa indexes, indicated noticeable variations in the rates of detection from laboratory to laboratory. Among the different tests used in the common procedure, regular APTT was the least sensitive (about 50% detection) but none of the other tests alone recognized more than 73% of specimens from the LA positive population. This yield increased to about 90% with any combination of 2 sensitive tests.(ABSTRACT TRUNCATED AT 250 WORDS)

    Race, David G; Malin, Nigel A

    2011-12-01

    This is the second of two articles examining links between policy developments and changes in professional practice within learning disability services in England. The first article focused on policy foundations over the last 30 years, and concluded that there was a developing gap in professional inputs between children's and adult services. This article, written one year into the Coalition government, argues that its policies--especially the large-scale reduction in public expenditure, but also the decline in support for inclusion of children in mainstream education, the rapid growth of academies, and proposals for the reorganization of the NHS--have exacerbated the trends identified earlier. In addition, local authorities, though outwardly compliant, have variously interpreted their responsibilities under the personalization agenda, in particular in relation to individual budgets, and this has resulted in assessments of need being based on 'service hours' rather than service quality and staff qualifications.

    Intensive induction chemotherapy using anthracycline and cytarabine backbone is considered the most effective upfront therapy in physically fit older patients with acute myeloid leukemia (AML). However, outcomes of the standard induction in elderly AML are inferior to those observed in younger patients, and they are still unsatisfactory. As addition of cladribine to the standard induction therapy is known to improve outcome in younger AML patients. The present randomized phase II study compares efficacy and toxicity of the DAC (daunorubicin plus cytarabine plus cladribine) regimen with the standard DA (daunorubicin plus cytarabine) regimen in the newly diagnosed AML patients over 60 years of age. A total of 171 patients were enrolled in the study (DA, 86; DAC, 85). A trend toward higher complete remission (CR) was observed in the DAC arm compared to the DA arm (44% vs. 34%; P = .19), which did not lead to improved median overall survival, which in the case of the DAC group was 8.6 months compared to in 9.1 months in the DA group (P = .64). However, DAC appeared to be superior in the group of patients aged 60-65 (CR rate: DAC 51% vs. DA 29%; P = .02). What is more, a subgroup of patients, with good and intermediate karyotypes, benefited from addition of cladribine also in terms of overall survival (P = .02). No differences in hematological and nonhematological toxicity between the DA and DAC regimens were observed.

    2012-01-01

    The Internet has revolutionized education and social communication in the 21st century. This article reviews the growing literature identifying a number of adolescents and young adults with a pathologically excessive Internet use leading to many potential consequences. Current research dilemmas in this area include that Internet addiction is a broad topic with no standard definition and no standard measurement tools. Management of youth with identified problematic Internet use or misuse centers on behavioral therapy and treatment of comorbidities. Pharmacologic approaches are limited at this time but are undergoing research, such as use of opioid antagonists and antidepressants in adults with pathological gambling. Efforts should be expanded on not only the education of all adolescents regarding the benefits but also the potential negative consequences of Internet use. It is vital that we do this for Generation Z, whereas Generation ALPHA will soon benefit or suffer from our efforts in this regard today.

Methods Food categories and concentration limits for lead in China were compared with those of CAC, European Union, Australia and New Zealand. Results Con-sidering the international risk assessment result of lead, China almost set MLs for all the food that possibly contributes to the dietary exposure of lead, so the food categories for lead in China were more than those in CAC, the European Union and Australia and New Zealand standards. However, some MLs of lead in China are still looser than those in CAC or other countries. Conclusion The measures to control major contributing sources of lead in food and the comprehensive national survey of lead contamination in food should be taken, in order to lay the foundation for further improvement of the food contaminants standard in China.

    Despite its many imperfections, the peer review process is a firmly established quality control system for scientific literature. It gives readers some assurance that the work and views that are reported meet standards that are acceptable to a journal. Maureen Revington's editorial in a recent issue of the Australian Veterinary Journal (Revington2002) gives a good concise warts and all overview of the process and is well worth reading. I have some concerns about several articles in the December 2002 issue of the New Zealand Veterinary Journal (Volume 50, Number 6), devoted to the health and welfare of farmed deer, that relate to extensive citing of non-peer reviewed papers. I can understand the need for information to flow from researchers to the wider community but that need is already satisfied by publications such as the proceedings of the Deer Branch of the New Zealand Veterinary Association and Proceedings of the New Zealand Society of Animal Production. Non-peer reviewed papers have been cited in the Journal in the past but never to the extent displayed in this particular issue. It degrades the peer-review process and creates an added burden for reviewers who are forced to grapple with the uncertainties of the science in non-peer reviewed citations. One of my fears is that this process allows science from non peer reviewed articles to be legitimised by its inclusion in a peer reviewed journal and perhaps go on to be accepted as dogma. This is a real danger given the difficulties associated with tracing back to original citations and the increasing volume of scientific literature. It also affords opportunities for agencies to pick up questionable and doubtful science and tout it as support for their products or particular points of view. If deer researchers choose to publish most of their work in proceedings then so be it. However this approach, which seems to becoming increasingly prevalent in the deer sector, is questionable from an established science point

    Full Text Available Chrysoperla carnea (Green lacewing is voracious predator of insect eggs and varieties of soft-bodied arthropods such as caterpilllars, aphids, jassids and mealy bugs. It is currently mass-reared and used in biological control of insect pests. Experiments were conducted to find out a better and cheaper artificial diet for mass-rearing of adult C. carnea. Three adult diets were tested in the laboratory conditions in comparison with standard diet; that was mixture of yeast extract, casein, honey, sugar and distilled water. Parameters were fecundity, larval period, pupal period and adult longevity. The results revealed that the mixture of egg yolk, milk and honey was better than all other diets.

    The appearance of the first volume of a projected series is the occasion for comment on scope, aims, and genesis of the work. The scope of Current Ornithology is all of the biology of birds. Ornithology, as a whole-organism science, is concerned with birds at every level of bi­ ological organization, from the molecular to the community, at least from the Jurassic to the present time, and over every scholarly discipline in which bird biology is done; to say this is merely to expand a dic­ tionary definition of "ornithology. " The aim of the work, to be realized over several volumes, is to present reviews or position statements con­ cerning the active fields of ornithological research. The reviews will be relatively short, and often will be done from the viewpoint of a readily­ identified group or school. Such a work could have come into being at any time within the past fifty years, but that Current Ornithology appears now is a result of events that are only seven to eight years old. One important event wa...

    Adult respiratory distress syndrome (ARDS) has now been described as a sequela to such diverse conditions as burns, amniotic fluid embolism, acute pancreatitis, trauma, sepsis and damage as a result of elective surgery in general. Patients with ARDS require immediate intubation, with the average patient now being ventilated for between 8 and 11 days. While the acute management of ARDS is conducted by the critical care team, almost any surgical patient can be affected by the condition and we believe that it is important that a broader spectrum of hospital doctors gain an understanding of the nature of the pathology and its current treatment.

    Older adult cancer survivors currently account for almost 60% of all cancer survivors. The number of older cancer survivors will continue to increase as the population ages and as patients' live longer after a cancer diagnosis. As part of cancer center accreditation, the American College of Surgeons Commission on Cancer® (CoC) has placed great importance on survivorship care planning. While the CoC has set standards for general survivorship care, there is sparse evidence on how to best care for older adult cancer survivors. Concern exists among the medical community that survivorship care plans could increase paperwork without improving outcomes. Given the diverse and unique needs of older adult cancer survivors, the inter-professional team provides a structure and process for survivorship care built around the particular needs of older adults. The Cancer and Aging Research Group (CARG), in partnership with the NIA/NCI, held a U13 conference in May 2015 in part to discuss survivorship care for older adults with cancer. This report discusses four themes that emerged from one section of the conference: (1) survivorship care is a process that continually evolves to meet the needs of older adults; (2) older adult cancer survivors have unique needs and care plans should be tailored to meet these needs; (3) the inter-professional team is ideally suited to structure survivorship care of older adults; (4) patient advocacy must be encouraged throughout the cancer care continuum. As evidence based survivorship practices develop, the unique needs of older adults need to be given substantial attention.

    Background In resource-limited countries, estimating CD4-specific incidence rates of mortality and morbidity among patients receiving antiretroviral therapy (ART) may help assess the effectiveness of care and treatment programmes, identify program weaknesses and inform decisions. Methods We pooled data from 13 research cohorts in five sub-Saharan African (Benin, Burkina Faso, Cameroon, Cote d'Ivoire and Senegal) and two Asian (Cambodia and Laos) countries. HIV-infected adults (≥18 years) who received ART in 1998-2008 and had at least one CD4 count available were eligible. Changes in CD4 counts over time were estimated by a linear mixed regression. CD4-specific incidence rates were estimated as the number of first events occurring in a given CD4 stratum divided by the time spent within the stratum. Results Overall 3,917 adults (62% women) on ART were followed-up during 10,154 person-years. In the ≤50, 51-100, 101-200, 201-350, 351-500, 501-650 and >650/mm3 CD4 cells strata, death rates were: 20.6, 11.8, 6.7, 3.3, 1.8, 0.9 and 0.3 per 100 person-years; AIDS rates were: 50.5, 32.9, 11.5, 4.8, 2.8, 2.2 and 2.2 per 100 person-years; and loss to follow-up rates were: 4.9, 6.1, 3.5, 3.1, 2.9, 1.7 and 1.2 per 100 person-years, respectively. Mortality and morbidity were higher during the first year following ART initiation. Conclusion In these resource-limited settings, death and AIDS rates remained substantial after ART initiation, even in individuals with high CD4 cell counts. Ensuring earlier ART initiation and optimizing case finding and treatment for AIDS-defining diseases should be seen as priorities. PMID:23274931

    Full Text Available Abstract Introduction Supratentorial primitive neuroectodermal tumors predominantly occur in children, and are rare in the adult population. Less than 100 cases of supratentorial primitive neuroectodermal tumor have been reported in adults internationally. Our case study reports this rare incident. Case presentation A 22-year-old Hispanic man presented with headaches, blurry vision, diplopia, intermittent vomiting, and grossly decreased vision. A magnetic resonance image showed a left posterior parietal heterogeneously enhancing mass measuring 4.2cm × 7.2cm × 7.0cm. After craniotomy for resection and decompression, the mass was histologically revealed to be a supratentorial primitive neuroectodermal tumor. Standardized immunohistochemical studies for this mass were carried out. Conclusion We have concluded that immunohistochemical and genetic workup should be included in the standardized pathological workup for primitive neuroectodermal tumors in order to provide more prognostic information. Based on our current literature review, we propose an immunohistochemical panel.

    Full Text Available The objectives of this review were to discuss standard and investigational treatment strategies for adolescent and young adult with acute myeloid leukemia, excluding acute promyelocytic leukemia. Acute myeloid leukemia (AML in adolescent and young adult patients (AYAs may need a different type of therapy than those currently used in children and older patients. As soon as AML is diagnosed, AYA patient should be offered to participate in well-designed clinical trials. The standard treatment approach for AYAs with AML is remission induction chemotherapy with an anthracycline/cytarabine combination, followed by either consolidation chemotherapy or stem cell transplantation, depending on the ability of the patient to tolerate intensive treatment and cytogenetic features. Presently, continuing progress of novel drugs targeting specific pathways in acute leukemia may bring AML treatment into a new era.

The patients (n = 25/arm) were treated with (i) two fixed-dose tablets (AS-MQ arm; 100 mg AS-200 mg MQ/tablet) daily for 3 days (days 0, 1, and 2) or (ii) nonfixed AS (AS-plus-MQ arm; 4 mg/kg of body weight/day for 3 days) plus MQ (15 mg/kg on day 1 and 10 mg/kg on day 2), dosed by weight. Clinical laboratory electrocardiogram (ECG), adverse events (AEs), efficacy, and pharmacokinetic parameters were assessed over 28 days. Both regimens were well tolerated. No AEs were drug related. Two serious AEs of malaria-induced hypotension occurring in the AS-MQ arm necessitated rescue treatment. There were no significant changes in hematology, biochemistry, or PR and QRS intervals. For all patients, mean Fridericia-corrected QT intervals were significantly (P ≤ 0.0027) prolonged on day 3 (407 ms) and day 7 (399 ms) versus day 0 (389 ms), in parallel with significant (P ≤ 0.0003) falls in heart rates (67 [day 3], 73 [day 7], and 83 [day 0] beats/minute). Fixed-nonfixed formulations were bioequivalent for MQ, but not for AS and dihydroartemisinin (DHA). One AS-MQ patient developed a new infection on day 28; his day 28 plasma MQ concentration was 503.8 ng/ml. Fixed-dose AS-MQ was well tolerated, had pharmacokinetic (PK) profiles broadly similar to those of nonfixed AS plus MQ, and is a suitable replacement. PMID:20547795

  12. Bone regeneration: current concepts and future directions

    2011-05-01

    Full Text Available Abstract Bone regeneration is a complex, well-orchestrated physiological process of bone formation, which can be seen during normal fracture healing, and is involved in continuous remodelling throughout adult life. However, there are complex clinical conditions in which bone regeneration is required in large quantity, such as for skeletal reconstruction of large bone defects created by trauma, infection, tumour resection and skeletal abnormalities, or cases in which the regenerative process is compromised, including avascular necrosis, atrophic non-unions and osteoporosis. Currently, there is a plethora of different strategies to augment the impaired or 'insufficient' bone-regeneration process, including the 'gold standard' autologous bone graft, free fibula vascularised graft, allograft implantation, and use of growth factors, osteoconductive scaffolds, osteoprogenitor cells and distraction osteogenesis. Improved 'local' strategies in terms of tissue engineering and gene therapy, or even 'systemic' enhancement of bone repair, are under intense investigation, in an effort to overcome the limitations of the current methods, to produce bone-graft substitutes with biomechanical properties that are as identical to normal bone as possible, to accelerate the overall regeneration process, or even to address systemic conditions, such as skeletal disorders and osteoporosis.

    Opiate use patterns, user characteristics, and treatment response among young adults are of interest due to current high use prevalence and historical low levels of treatment engagement relative to older populations. Prior research in this population suggests that overall, young adults present at treatment with different issues. In this study the authors investigated potential differences between young adult (18-25 years of age) and older adult (26 and older) opiate users and the impact of differences relative to treatment motivation, length and outcomes. Data for this study was drawn from 760 individuals who entered voluntary, private, residential treatment. Study measures included the Addiction Severity Index (ASI), the Treatment Service Review (TSR), and University of Rhode Island Change Assessment (URICA). Interviews were conducted at program intake and 6-month post-discharge. Results indicate that older adults with a history of opiate use present at treatment with higher levels of severity for alcohol, medical, and psychological problems and young adults present at treatment with greater drug use and more legal issues. Significant improvement for both groups was noted at 6 months post treatment; there were also fewer differences between the two age groups of opiate users. Results suggest different strategies within treatment programs may provide benefit in targeting the disparate needs of younger opiate users. Overall, however, results suggest that individualized treatment within a standard, abstinence-based, residential treatment model can be effective across opiate users at different ages and with different issues, levels of severity, and impairment at intake.

  19. Clopidogrel Resistance: Current Issues

    2016-05-01

    Full Text Available Antiplatelet agents are mainly used in the prevention and management of atherothrombotic complications. Dual antiplatelet therapy, combining aspirin and clopidogrel, is the standard care for patients having acute coronary syndromes or undergoing percutaneous coronary intervention according to the current ACC/AHA and ESC guidelines. But in spite of administration of dual antiplatelet therapy, some patients develop recurrent cardiovascular ischemic events especially stent thrombosis which is a serious clinical problem. Antiplatelet response to clopidogrel varies widely among patients based on ex vivo platelet function measurements. Clopidogrel is an effective inhibitor of platelet activation and aggregation due to its selective and irreversible blockade of the P2Y12 receptor. Patients who display little attenuation of platelet reactivity with clopidogrel therapy are labeled as low or nonresponders or clopidogrel resistant. The mechanism of clopidogrel resistance remains incompletely defined but there are certain clinical, cellular and genetic factors including polymorphisms responsible for therapeutic failure. Currently there is no standardized or widely accepted definition of clopidogrel resistance. The future may soon be realised in the routine measurement of platelet activity in the same way that blood pressure, cholesterol and blood sugar are followed to help guide the therapy, thus improving the care for millions of people. This review focuses on the methods used to identify patients with clopidogrel resistance, the underlying mechanisms, metabolism, clinical significance and current therapeutic strategies to overcome clopidogrel resistance.

    We have created the Knowledgebase of Standard Biological Parts (SBPkb) as a publically accessible Semantic Web resource for synthetic biology (sbolstandard.org). The SBPkb allows researchers to query and retrieve standard biological parts for research and use in synthetic biology. Its initial version includes all of the information about parts stored in the Registry of Standard Biological Parts (partsregistry.org). SBPkb transforms this information so that it is computable, using our semantic framework for synthetic biology parts. This framework, known as SBOL-semantic, was built as part of the Synthetic Biology Open Language (SBOL), a project of the Synthetic Biology Data Exchange Group. SBOL-semantic represents commonly used synthetic biology entities, and its purpose is to improve the distribution and exchange of descriptions of biological parts. In this paper, we describe the data, our methods for transformation to SBPkb, and finally, we demonstrate the value of our knowledgebase with a set of sample queries. We use RDF technology and SPARQL queries to retrieve candidate "promoter" parts that are known to be both negatively and positively regulated. This method provides new web based data access to perform searches for parts that are not currently possible.

    Perform Achieve Trade (PAT) is a market-based incentive mechanism to promote energy efficiency. The purpose of this work is to address the challenges inherent to inconsistent representation of business processes, and interoperability issues in PAT like cap-and-trade mechanisms especially when scaled. Studies by various agencies have highlighted that as the mechanism evolves including more industrial sectors and industries in its ambit, implementation will become more challenging. This paper analyses the major needs of PAT (namely tracking, monitoring, auditing & verifying energy-saving reports, and providing technical support & guidance to stakeholders); and how the aforesaid reasons affect them. Though current technologies can handle these challenges to an extent, standardization activities for implementation have been scanty for PAT and this work attempts to evolve them. The inconsistent modification of business processes, rules, and procedures across stakeholders, and interoperability among heterogeneous systems are addressed. This paper proposes the adoption of specifically two standards into PAT, namely Business Process Model and Notation for maintaining consistency in business process modelling, and Common Information Model (IEC 61970, 61968, 62325 combined) for information exchange. Detailed architecture and organization of these adoptions are reported. The work can be used by PAT implementing agencies, stakeholders, and standardization bodies.

    Highlights: •BSG are classified on MRI into diffuse low-grade, malignant, focal tectal and exophytic subtypes. •Their prognosis and treatment is variable and is almost similar to adult supratentorial gliomas. •This article illustrates the imaging of adult BSGs on MRI and FET-PET. •We also describe prognostic factors and the treatment options of these tumours. -- Abstract: Brainstem gliomas (BSGs) are uncommon in adults accounting for about 2% of all intracranial neoplasms. They are often phenotypically low-grade as compared to their more common paediatric counterparts. Since brainstem biopsies are rarely performed, these tumours are commonly classified according to their MR imaging characteristics into 4 subgroups: (a) diffuse intrinsic low-grade gliomas, (b) enhancing malignant gliomas, (c) focal tectal gliomas and (d) exophytic gliomas/other subtypes. The prognosis and treatment is variable for the different types and is almost similar to adult supratentorial gliomas. Radiotherapy (RT) with adjuvant chemotherapy is the standard treatment of diffuse low-grade and malignant BSGs, whereas, surgical resection is limited to the exophytic subtypes. Review of previous literature shows that the detailed imaging of adult BSGs has not received significant attention. This review illustrates in detail the imaging features of adult BSGs using conventional and advanced MR techniques like diffusion weighted imaging (DWI), diffusion tensor imaging (DTI), MR perfusion weighted imaging (PWI), MR spectroscopy (MRS), as well as {sup 18}F-fluoro-ethyl-tyrosine positron emission tomography ({sup 18}F-FET/PET). We have discussed the pertinent differences between childhood and adult BSGs, imaging mimics, prognostic factors and briefly reviewed the treatment options of these tumours.

    The authors critically examine some of the underlying epistemological and theoretical assumptions of the IALS. In doing so, they distinguish among two basic orientations towards literacy. First, the standard approach (of which IALS is an example) subscribes to the possibility of measuring literacy as abstract, cognitive skills, and endorses the claim that there is an important relationship between literacy skills and economic success in the so-called 'knowledge society.' The second, called a socio-cultural approach, insists on the contextual and power-related character of people's literacy practices. The authors further illustrate that the assumptions of the IALS are rooted in a neo-liberal ideology that forces all members of society to adjust to the exigencies of the globalised economy. In the current, contingent conditions of the risk society, however, it does not seem very wise to limit the learning of adults to enhancing labour-market competencies. Adult education should relate to the concrete literacy practices people already have in their lives. It should make its learners co-responsible actors of their own learning process and participants in a democratic debate on defining the kind of society people want to build.

    The prevalence of food allergy is increasing in both the pediatric and adult populations. While symptom onset occurs mostly during childhood, there are a considerable number of patients whose symptoms first begin to appear after the age of 18 years. The majority of patients with adult-onset food allergy suffer from the pollen-plant allergy syndromes. Many of them manifest their allergy after exercise and consuming food to which they are allergic. Eosinophilic esophagitis, an eosinophilic inflammation of the esophagus affecting individuals of all ages, recently emerged as another allergic manifestation, with both immediate and late response to the ingested food. This review provides a condensed update of the current data in the literature on adult-onset allergy.

    2005-01-01

    In the rapid development course of laser technology and modern optics, optical metrology continuously gains importance for the quality management in the industrial production environment and also for research in optical coatings. Besides absorption and scatter losses, the spectral characteristics and laser induced damage thresholds are considered as common quality factors for coated optical components and often define the optimization targets for new products and applications. Also, these quality parameters are the basis for the comparison of commercial optics and can be found in the product catalogues of most manufacturers of optical components. As a consequence, standardization of characterisation procedures for these fundamental properties evolved to a crucial point for the optics industry. During the last decade, adapted standard measurement techniques have been elaborated and discussed by representatives from many industrial companies and research institutes within working groups of the International Organisation for Standardization (ISO). In this contribution, the current state of standardized characterisation techniques for optical coatings is summarised. Selected standards for the measurement of absorption (ISO 11551), scattering (ISO 13696) and laser induced damage thresholds (ISO 11254, Parts 1 and 2) will be described and discussed in view of their applicability and reproducibility. The report will be concluded by an outlook on the current projects and future tasks of standardization in optics characterisation.

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

    1999-01-01

    Acrylonitrile is a colourless liquid with a faintly sweet and pungent odour. It is widely used as a chemical intermediate in a variety of industrial and commercial products such as acrylic and modacrylic fibres, plastics, styrene-acrylonitrile, nitrile rubber resins, and acrylamide. Although not currently produced in Canada, acrylonitrile is used in the manufacture of industrial and commercial products. Acrylonitrile levels around end-use plants have been found to be significantly higher than at producing facilities. Almost all releases of acrylonitrile are to the atmosphere and one facility is responsible for all releases in Ontario. Human exposure is through air, water and food. Acrylonitrile is absorbed by inhalation, through the mouth and to some extent through the skin. Exposure at concentrations of 7 to 45 microgram/cubic meter for 20 to 45 minutes leads to irritation of the mucous membranes, nausea, headaches, and irritability. Low-grade anaemia, leukocytosis, kidney irritation and mild jaundice have also been observed. Children are more sensitive than adults. Acrylonitrile is classified as probable human carcinogen by the US Environmental Protection Agency. The current ambient air quality criterion (AAQC) in Ontario is 100 microgram/cubic metre and the half-hour interim point of impingement (POI) standard is 300 microgram/cubic meter. Review of world-wide literature showed the existence of standards in several American states. Cancer unit risks estimates have been made by the US Environmental Protection Agency as well as by the World Health Organization. 63 refs., 1 tab., appendix.

    Abstract Background Attention deficit hyperactivity disorder (ADHD) is among the most common psychiatric disorders of childhood that persists into adulthood in the majority of cases. The evidence on persistence poses several difficulties for adult psychiatry considering the lack of expertise for diagnostic assessment, limited treatment options and patient facilities across Europe. Methods The European Network Adult ADHD, founded in 2003, aims to increase awareness of this disorder and improve knowledge and patient care for adults with ADHD across Europe. This Consensus Statement is one of the actions taken by the European Network Adult ADHD in order to support the clinician with research evidence and clinical experience from 18 European countries in which ADHD in adults is recognised and treated. Results Besides information on the genetics and neurobiology of ADHD, three major questions are addressed in this statement: (1) What is the clinical picture of ADHD in adults? (2) How can ADHD in adults be properly diagnosed? (3) How should ADHD in adults be effectively treated? Conclusions ADHD often presents as an impairing lifelong condition in adults, yet it is currently underdiagnosed and treated in many European countries, leading to ineffective treatment and higher costs of illness. Expertise in diagnostic assessment and treatment of ADHD in adults must increase in psychiatry. Instruments for screening and diagnosis of ADHD in adults are available and appropriate treatments exist, although more research is needed in this age group.

    Diabetes is a serious chronic condition,which increase the risk of cardiovascular diseases,kidney failure and nerve damage leading to amputation.Furthermore the ocular complications include diabetic macular edema,is the leading cause of blindness among adults in the industrialized countries.Today,blindness from diabetic macular edema is largely preventable with timely detection and appropriate interventional therapy.The treatment should include an optimized control of glycemia,arterial tension,lipids and renal status.The photocoagulation laser is currently restricted to focal macular edema in some countries,but due the high cost of intravitreal drugs,the use of laser treatment for focal and diffuse diabetic macular edema(DME),can be valid as gold standard in many countries.The intravitreal anti vascular endothelial growth factor drugs(ranibizumab and bevacizumab),are indicated in the treatment of all types of DME,but the correct protocol for administration should be defined for the different Retina Scientific Societies.The corticosteroids for diffuse DME,has a place in pseudophakic patients,but its complications restricted the use of these drugs for some patients.Finally the intravitreal interface plays an important role and its exploration is mandatory in all DME patients.

    Adult neurogenesis has been linked to several cognitive functions and neurological disorders. Description of adult neurogenesis in a model organism like Drosophila could facilitate the genetic study of normal and abnormal neurogenesis in the adult brain. So far, formation of new neurons has not been detected in adult fly brains and hence has been thought to be absent in Drosophila. Here, we used an improved lineage-labeling method to show that, surprisingly, adult neurogenesis occurs in the m...

    Malinowski, Scott S; Byrd, Jennifer S; Bell, Allison M; Wofford, Marion R; Riche, Daniel M

    2013-02-01

    Nonalcoholic fatty liver disease (NAFLD) is characterized by the accumulation of triglycerides in hepatocytes in the absence of excessive alcohol intake, ranging in severity from simple steatosis to nonalcoholic steatohepatitis (NASH). Nonalcoholic steatohepatitis can ultimately progress to cirrhosis and hepatocellular carcinoma. NAFLD is associated with cardiometabolic risk factors and is the most common chronic liver disease among adults in the Western Hemisphere. Although simple steatosis is generally considered a self-limiting disease, evidence suggests an increased risk of cardiovascular disease, and, less conclusively, mortality, among individuals with NAFLD and/or NASH. The current standard of care for the treatment of patients with NAFLD focuses on lifestyle interventions, particularly diet and exercise. There is a lack of consensus regarding the most effective and appropriate pharmacologic therapy. A PubMed search was conducted using the medical subject heading terms "fatty liver" and "steatohepatitis." This review focuses on the current pharmacologic options available for treating adults with NAFLD and/or NASH. Continued investigation of drugs or combinations that improve NAFLD progression is crucial. Clinicians, particularly pharmacists, must take an active role in identification and appropriate selection of pharmacotherapy for NAFLD.

    We investigate determinants of subjective social status (SSS) as measured by respondents placing themselves on a ten-rung ladder from least to most "money", "education" and "respected job", in a large sample of young adults. The most potent clues of SSS are proximate in the life course, reflecting educational attainment and current socioeconomic and job situation, rather than distal characteristics such as family background, although relatively distal High school GPA has a lingering effect. Additional analyses reveal that College selectivity has a substantial impact on SSS, net of other variables in the model; Currently married does not significantly contribute to SSS, but contrary to some expectations Number of children significantly lowers SSS. We find no evidence of greater "status borrowing" by women as associations of SSS with shared household characteristics (Household income, Household assets, Home ownership) do not differ by gender. Our findings for these young adults support the conclusion of earlier research that SSS reflects a "cognitive averaging" of standard dimensions of socioeconomic status.

    2011-09-01

    Adults with ADHD have problems in everyday multitasking situations presumably because of deficits in executive functions. The present study aims to find out (a) whether adults with ADHD show deficient multitasking performance in a standardized task, (b) how they perceive the multitasking situation, and (c) which task structure might be beneficial for them as compared with adults without ADHD. Therefore, we experimentally compared task performance, mood, and motivation in a group of 45 men with ADHD (M-age = 34.47, SD = 9.95) with a comparison group of 42 men without ADHD (M-age = 31.12, SD = 10.59) in three conditions: (a) a multitasking paradigm, (b) an interleaving condition in which tasks had to be performed without planning or monitoring, and (c) a non-interleaving condition. Our results showed no impaired multitasking performance in adults with ADHD. However, they showed better mood and more motivation in the non-interleaving condition.

  18. Current Approaches in the Treatment of Relapsed and Refractory Acute Myeloid Leukemia

    Directory of Open Access Journals (Sweden)

    Nestor R. Ramos

    2015-04-01

    Full Text Available The limited sensitivity of the historical treatment response criteria for acute myeloid leukemia (AML has resulted in a different paradigm for treatment compared with most other cancers presenting with widely disseminated disease. Initial cytotoxic induction chemotherapy is often able to reduce tumor burden to a level sufficient to meet the current criteria for “complete” remission. Nevertheless, most AML patients ultimately die from their disease, most commonly as clinically evident relapsed AML. Despite a variety of available salvage therapy options, prognosis in patients with relapsed or refractory AML is generally poor. In this review, we outline the commonly utilized salvage cytotoxic therapy interventions and then highlight novel investigational efforts currently in clinical trials using both pathway-targeted agents and immunotherapy based approaches. We conclude that there is no current standard of care for adult relapsed or refractory AML other than offering referral to an appropriate clinical trial.

  20. Perspectives on housing among homeless emerging adults.

    Ryan, Tiffany N; Thompson, Sanna J

    2013-02-01

    Homeless emerging adults need the safety and stability of housing programs if they are to avoid the elements and victimization of the streets, however, barriers to obtaining housing are numerous. This study identified factors associated with perspectives of housing services among 29 homeless emerging adults (ages 18-23 years) through one-on-one interviews. Data were gathered and analyzed using grounded theory methodology for qualitative information. Major themes of peer support and positive personal and programmatic interactions in the context of emerging adult development were noted as important factors in housing service utilization. These major themes should be taken into consideration for current housing programs, due to homeless emerging adults' oscillation between their desire for formal support and personal independence. Greater emphasis on services that do not require long term commitments and are more flexible in addressing specific barriers to housing for homeless emerging adults may increase use.

  1. [Vesicoureteral reflux in adults].

    2011-01-01

    Vesicoureteral reflux (VUR) may be congenital or acquired. The most frequent form of congenital VUR is primary VUR. Its prevalence in adults is not exactly known, but it is higher in women, whose greater propensity for urinary tract infections increases the likelihood of an instrumental examination leading to the diagnosis of less severe cases. In men, even severe VUR may go undiagnosed for a long time. Primary VUR is due to a defect in the valve mechanism of the ureterovesical junction. In physiological conditions, the terminal ureter enters the bladder wall obliquely and bladder contraction leads to compression of this intravesical portion. Abnormal length of the intravesical portion of the ureter due to a genetic mutation (whose location is yet to be established) leads to VUR. In its less severe forms VUR may be asymptomatic, but in 50-70% of cases it manifests with recurrent cystitis or pyelonephritis. The manifestations leading to a diagnosis of VUR in adults, besides urinary tract infections, are proteinuria, renal failure and hypertension. The gold-standard diagnostic examination is a micturating cystourethrogram. Reflux nephropathy develops as a result of a pathogenetic mechanism unrelated to high cavity pressure or urinary tract infections but due to reduced formation of the normal renal parenchyma (hypoplasia or dysplasia). Abnormal renal parenchyma development is attributable to the same genes that control the development of the ureters and ureterovesical junction. VUR is considered only a marker of this abnormal development, playing no role in scar formation. There is no conclusive evidence regarding the indications for VUR correction. However, the risk that VUR leads to recurrent pyelonephritis and reflux nephropathy must be kept in mind. VUR certainly has to be corrected in women who contemplate pregnancy.

    2017-01-01

    Objectives The primary objective of this systematic review was to determine the accuracy of point-of-care ultrasonography (POCUS) in diagnosing abscess in emergency department (ED) patients with skin and soft tissue infections (SSTI). The secondary objective was the accuracy of POCUS in the paediatric population subgroup. Setting Prospective studies set in emergency departments. Participants Emergency department patients (adult and paediatric) presenting with SSTI and suspected abscess. Primary and secondary outcome measures This systematic review was conducted according to Cochrane Handbook guidelines, and the following databases were searched: PubMed, MEDLINE, EMBASE and the Cochrane database of systematic reviews (1946–2015). We included prospective cohort and case–control studies investigating ED patients with SSTI and abscess or cellulitis, a defined POCUS protocol, a clearly defined gold standard for abscess and a contingency table describing sensitivity and specificity. Two reviewers independently ascertained all potentially relevant citations for methodologic quality according to QUADAS-2 criteria. The primary outcome measure was the sensitivity and specificity of POCUS for abscess. A preplanned subgroup (secondary) analysis examined the effects in paediatric populations, and changes in management were explored post hoc. Results Of 3028 articles, 8 were identified meeting inclusion criteria; all were rated as good to excellent according to QUADAS-2 criteria. Combined test characteristics of POCUS on the ED diagnosis of abscess for patients with SSTI were as follows: sensitivity 96.2% (95% CI 91.1% to 98.4%), specificity 82.9% (95% CI 60.4% to 93.9%), positive likelihood ratio 5.63 (95% CI 2.2 to 14.6) and negative likelihood ratio 0.05 (95% CI 0.01 to 0.11). Conclusions A total of 8 studies of good-to-excellent quality were included in this review. The use of POCUS helps differentiate abscess from cellulitis in ED patients with SSTI. Trial registration

    Humidification of inhaled gases has been standard of care in mechanical ventilation for a long period of time. More than a century ago, a variety of reports described important airway damage by applying dry gases during artificial ventilation. Consequently, respiratory care providers have been utilizing external humidifiers to compensate for the lack of natural humidification mechanisms when the upper airway is bypassed. Particularly, active and passive humidification devices have rapidly evolved. Sophisticated systems composed of reservoirs, wires, heating devices, and other elements have become part of our usual armamentarium in the intensive care unit. Therefore, basic knowledge of the mechanisms of action of each of these devices, as well as their advantages and disadvantages, becomes a necessity for the respiratory care and intensive care practitioner. In this paper, we review current methods of airway humidification during invasive mechanical ventilation of adult patients. We describe a variety of devices and describe the eventual applications according to specific clinical conditions.

    Willoughby, Brian J; Hall, Scott S; Goff, Saige

    2015-01-01

    Marriage, once a gateway to adulthood, is no longer as widely considered a requirement for achieving adult status. With declining marriage rates and delayed marital transitions, some have wondered whether current young adults have rejected the traditional notion of marriage. Utilizing a sample of 571 young adults, the present study explored how marital centrality (the expected importance to be placed on the marital role relative to other adult roles) functioned as a unique and previously unexplored marital belief among young adults. Results suggested that marriage remains an important role for many young adults. On average, young adults expected that marriage would be more important to their life than parenting, careers, or leisure activities. Marital centrality profiles were found to significantly differ based on both gender and religiosity. Marital centrality was also associated with various outcomes including binge-drinking and sexual activity. Specifically, the more central marriage was expected to be, the less young adults engaged in risk-taking or sexual behaviors.

    This paper suggests that when the phenomenon of standards and standardization is examined from the perspective of organization studies, three aspects stand out: the standardization of organizations, standardization by organizations and standardization as (a form of) organization. Following...... a comprehensive overview of existing research in these three areas, we argue that the dynamic aspects of standardization are under-represented in the scholarly discourse. Furthermore, we identify the main types of tension associated with standardization and the dynamics they generate in each of those three areas......, and show that, while standards and standardization are typically associated with stability and sameness, they are essentially a dynamic phenomenon. The paper highlights the contributions of this special issue to the topic of standards as a dynamic phenomenon in organization studies and makes suggestions...

    2015-04-01

    Transcranial direct current stimulation has been gaining increasing interest as a potential therapeutic treatment in stroke recovery. We performed a systematic review with meta-analysis of randomized controlled trials to collate the available evidence in adults with residual motor impairments as a result of stroke. The primary outcome was change in motor function or impairment as a result of transcranial direct current stimulation, using any reported electrode montage, with or without adjunct physical therapy. The search yielded 15 relevant studies comprising 315 subjects. Compared with sham, cortical stimulation did not produce statistically significant improvements in motor performance when measured immediately after the intervention (anodal stimulation: facilitation of the affected cortex: standardized mean difference = 0.05, P = 0.71; cathodal stimulation: inhibition of the nonaffected cortex: standardized mean difference = 0.39, P = 0.08; bihemispheric stimulation: standardized mean difference = 0.24, P = 0.39). When the data were analyzed according to stroke characteristics, statistically significant improvements were evident for those with chronic stroke (standardized mean difference = 0.45, P = 0.01) and subjects with mild-to-moderate stroke impairments (standardized mean difference = 0.37, P = 0.02). Transcranial direct current stimulation is likely to be effective in enhancing motor performance in the short term when applied selectively to patients with stroke. Given the range of stimulation variables and heterogeneous nature of stroke, this modality is still experimental and further research is required to determine its clinical merit in stroke rehabilitation.

    Several neurological variables have been investigated as premorbid biomarkers of vulnerability for schizophrenia and other related disorders. The current study examined whether childhood dyspraxia predicted later adult nonaffective-psychosis-spectrum disorders. From a standardized neurological examination performed with children (aged 10-13) at genetic high risk of schizophrenia and controls, several measures of dyspraxia were used to create a scale composed of face/head dyspraxia, oral articulation, ideomotor dyspraxia (clumsiness), and dressing dyspraxia (n = 244). Multinomial logistic regression showed higher scores on the dyspraxia scale predict nonaffective-psychosis-spectrum disorders relative to other psychiatric disorders and no mental illness outcomes, even after controlling for genetic risk, χ2 (4, 244) = 18.61, p dyspraxia in childhood (reflecting abnormalities spanning functionally distinct brain networks) specifically predict adult nonaffective-psychosis-spectrum disorders are consistent with a theory of abnormal connectivity, and they highlight a marked early-stage vulnerability in the pathophysiology of nonaffective-psychosis-spectrum disorders.

    The zebrafish has become a standard model system for stem cell and tissue regeneration research, based on powerful genetics, high tissue regenerative capacity and low maintenance costs. Yet, these studies can be challenged by current limitations of tissue visualization techniques in adult animals. Here we describe new imaging methodology and present several ubiquitous and tissue-specific luciferase-based transgenic lines, which we have termed zebraflash, that facilitate the assessment of regeneration and engraftment in freely moving adult zebrafish. We show that luciferase-based live imaging reliably estimates muscle quantity in an internal organ, the heart, and can longitudinally follow cardiac regeneration in individual animals after major injury. Furthermore, luciferase-based detection enables visualization and quantification of engraftment in live recipients of transplanted hematopoietic stem cell progeny, with advantages in sensitivity and gross spatial resolution over fluorescence detection. Our findings present a versatile resource for monitoring and dissecting vertebrate stem cell and regeneration biology.

  12. Neutrinophilic Non-Standard Interactions

    Farzan, Yasaman

    2016-01-01

    We construct UV-complete models for non-standard neutrino interactions mediated by a sub-GeV gauge boson Z' coupled to baryon number $B$ or $B-L$. A flavor-dependent Z' coupling to neutrinos is induced by mixing a U(1)'-charged Dirac fermion with the active neutrinos, naturally suppressing flavor violation or non-universality of the charged leptons to the loop level. We show that these models can give rise to large flavor-conserving as well as flavor-violating non-standard neutral-current neutrino interactions potentially observable in current or future oscillation experiments such as DUNE without being in conflict with other constraints such as neutrino scattering or lepton-flavor-violating decays. In particular, the LMA-Dark solution to the solar-neutrino anomaly can be obtained for $U(1)_B$, but not for $U(1)_{B-L}$.

  13. Urinary tract infection in older adults.

    Rowe, Theresa A; Juthani-Mehta, Manisha

    2013-10-01

    Urinary tract infection and asymptomatic bacteriuria are common in older adults. Unlike in younger adults, distinguishing symptomatic urinary tract infection from asymptomatic bacteriuria is problematic, as older adults, particularly those living in long-term care facilities, are less likely to present with localized genitourinary symptoms. Consensus guidelines have been published to assist clinicians with diagnosis and treatment of urinary tract infection; however, a single evidence-based approach to diagnosis of urinary tract infection does not exist. In the absence of a gold standard definition of urinary tract infection that clinicians agree upon, overtreatment with antibiotics for suspected urinary tract infection remains a significant problem, and leads to a variety of negative consequences including the development of multidrug-resistant organisms. Future studies improving the diagnostic accuracy of urinary tract infections are needed. This review will cover the prevalence, diagnosis and diagnostic challenges, management, and prevention of urinary tract infection and asymptomatic bacteriuria in older adults.

  14. Neutrino and The Standard Model

    2014-01-01

    After discovery of the Higgs boson at CERN the Standard Model acquired a status of the full, correct theory of the elementary particles in the electroweak range. What general conclusions can be inferred from the SM? I am suggesting here that in the framework of such general principles as local gauge symmetry, unification of the weak and electromagnetic interactions and Brout-Englert-Higgs spontaneous breaking of the electroweak symmetry nature chooses the simplest possibilities. It is very plausible that massless left-handed neutrinos (simplest, most economical possibility) play crucial role in the determination of the charged current structure of the Standard Model and that neutrino properties (masses and nature) are determined by a beyond the Standard Model physics. The discovery of the neutrinoless double $\\beta$-decay and proof that neutrinos with definite masses are Majorana particles would be an important evidence in favor of the considered scenario.

    Older adults constitute the group with the greatest increase in Internet usage in the past decade; however, usage varies greatly within this population. Services to older adults require a current understanding of Internet-use trends. This study utilized a quantitative survey method to examine correlates of, and barriers to, current Internet use in a demographically diverse county in Southern California. Findings indicate that the presence of a computer at home, a job requiring computer use, age, education, and ethnicity are important factors in predicting Internet use in older adults. Implications for social work practice with older adults is discussed.

    2016-03-01

    In this review, the potential causes and consequences of adult height, a measure of cumulative net nutrition, in modern populations are summarized. The mechanisms linking adult height and health are examined, with a focus on the role of potential confounders. Evidence across studies indicates that short adult height (reflecting growth retardation) in low- and middle-income countries is driven by environmental conditions, especially net nutrition during early years. Some of the associations of height with health and social outcomes potentially reflect the association between these environmental factors and such outcomes. These conditions are manifested in the substantial differences in adult height that exist between and within countries and over time. This review suggests that adult height is a useful marker of variation in cumulative net nutrition, biological deprivation, and standard of living between and within populations and should be routinely measured. Linkages between adult height and health, within and across generations, suggest that adult height may be a potential tool for monitoring health conditions and that programs focused on offspring outcomes may consider maternal height as a potentially important influence.

    Prader-Willi syndrome (PWS) is a neurodevelopmental genetic disorder characterized by intellectual disabilities and insatiable appetite with compulsive eating leading to severe obesity with detrimental health consequences. Transcranial direct current stimulation (tDCS) has been shown to modulate decision-making and cue-induced food craving in healthy adults. We conducted a pilot double blind, sham-controlled, multicenter study of tDCS modulation of food drive and craving in 10 adult PWS participants, 11 adult obese (OB) and 11 adult healthy-weight control (HWC) subjects. PWS and OB subjects received five consecutive daily sessions of active or sham tDCS over the right dorsolateral prefrontal cortex (DLPFC), while HWC received a single sham and active tDCS in a crossover design. Standardized psychometric instruments assessed food craving, drive and hyperphagia by self-report and caregiver assessment over 30 days. Robust baseline differences were observed in severity scores for the Three-Factor Eating Questionnaire (TFEQ) and Dykens Hyperphagia Questionnaire (DHQ) for PWS compared to HWC while obese participants were more similar to HWC. Active tDCS stimulation in PWS was associated with a significant change from baseline in TFEQ Disinhibition (Factor II) (Ƶ = 1.9, P food drive and behaviors impacting hyperphagia in PWS. Transcranial direct current stimulation may represent a straight-forward, low risk and low cost method to improve care, management and quality of life in PWS.

    2016-06-01

    Cardiovascular disease (CVD) has been linked to decreases in driving performance and an increased crash risk. Regular exercise has been linked to improved driving performance among healthy adults. The aim of the current study was to investigate the relationship between a 12-week cardiac rehabilitation (CR) program and driving performance among individuals with CVD. Twenty-five individuals, including 12 cardiac adults and 13 healthy adults, took part in this study. Simulated driving performance was assessed using a standardized demerit-based scoring system at 0 and 12 weeks. Cardiac participants completed a 12-week CR program between evaluations. At baseline, cardiac participants had a higher number of demerit points than healthy adults (120.9±38.1 vs. 94.7±28.3, P=0.04). At follow-up, there was an improvement in both groups' driving evaluations, but the improvement was greater among the cardiac group such that there was no longer a difference in driving performance between both groups (94.6±30 vs. 86.9±34.8, P=0.51). Participation in an aerobic exercise-based CR program appears to lead to improvements in simulated driving performances of individuals with CVD.

The argument takes off from two different conceptualizations of standards in the literature. On the one hand, standards as immanent to practices (the “Neo-Aristotelian” approach), and on the other hand, standards as imposed to regulate practices (the “neo-pragmatist” and “governmentality” approaches......). It is suggested that this opposition can be superseded by articulating the former alternative, not as an essentialism of “practice,” but as the reflexive assumption of standpoint. Some intricacies of the articulation of standpoint are then discussed, concluding in a proposed dialectics of standard and standpoint....

  15. Lead toxicity: Current concerns

    Energy Technology Data Exchange (ETDEWEB)

    Goyer, R.A. (Univ. of Western Ontario, London (Canada))

    1993-04-01

    Over the 20-year period since the first issue of Environmental Health Perspectives was published, there has been considerable progress in the understanding of the potential toxicity of exposure to lead. Many of these advances have been reviewed in published symposia, conferences, and review papers in EHP. This brief review identifies major advances as well as a number of current concerns that present opportunities for prevention and intervention strategies. The major scientific advance has been the demonstration that blood lead (PbB) levels of 10-15 micrograms/dL in newborn and very young infants result in cognitive and behavioral deficits. Further support for this observation is being obtained by prospective or longitudinal studies presently in progress. The mechanism(s) for the central nervous system effects of lead is unclear but involve lead interactions within calcium-mediated intracellular messenger systems and neurotransmission. Effects of low-level lead exposure on blood pressure, particularly in adult men, may be related to the effect of lead on calcium-mediated control of vascular smooth muscle contraction and on the renin-angiotensin system. Reproductive effects of lead have long been suspected, but low-level effects have not been well studied. Whether lead is a carcinogen or its association with renal adenocarcinoma is a consequence of cystic nephropathy is uncertain. Major risk factors for lead toxicity in children in the United States include nutrition, particularly deficiencies of essential metals, calcium, iron, and zinc, and housing and socioeconomic status. A goal for the year 2000 is to reduce prevalence of blood lead levels exceeding 15 micrograms/dL. 97 refs.

    The workshop theme is `The Strategic Standardization Initiative - A Technology Exchange and Global Competitiveness Challenge for DOE.` The workshop goal is to inform the DOE technical standards community of strategic standardization activities taking place in the Department, other Government agencies, standards developing organizations, and industry. Individuals working on technical standards will be challenged to improve cooperation and communications with the involved organizations in response to the initiative. Workshop sessions include presentations by representatives from various Government agencies that focus on coordination among and participation of Government personnel in the voluntary standards process; reports by standards organizations, industry, and DOE representatives on current technology exchange programs; and how the road ahead appears for `information superhighway` standardization. Another session highlights successful standardization case studies selected from several sites across the DOE complex. The workshop concludes with a panel discussion on the goals and objectives of the DOE Technical Standards Program as envisioned by senior DOE management. The annual workshop on technical standards has proven to be an effective medium for communicating information related to standards throughout the DOE community. Technical standards are used to transfer technology and standardize work processes to produce consistent, acceptable results. They provide a practical solution to the Department`s challenge to protect the environment and the health and safety of the public and workers during all facility operations. Through standards, the technologies of industries and governments worldwide are available to DOE. The DOE Technical Standards Program, a Department-wide effort that crosscuts all organizations and disciplines, links the Department to those technologies.

    Full Text Available Theory of attachment primarily described early relationships between a child and his caretakers. In the last twenty years there is a growing interest in adult attachment research. Theories and research findings of adult attachment stem from two different methodological approaches. The first approach measures adult attachment through Adult Attachment Interview (AAI; Main, 1991 where the attachment is assessed through the narratives of adult people of their early child experiences with their primary caretakers. The second approach measures adult attachment with the help of self-evaluative questionnaires, developed by (a Hazan and Shaver (1987 who started this approach in the field of personality and social psychology, and (b Bartholomew and Horowitz (1991. Research shows that there is significant correlation between early and adult attachment style. Attachment styles are passed from generation to generation. Basic adult attachment styles are: securely attached, preoccupied, fearful-avoidant, dismissing-avoidant and disorganized. Previous research using Barholomew and Horowitz (1991 Relationship Questionnaire on 176 Slovenian students showed that 48% students are securely attached, 29% are fearful-avoidant, 10% are dismissing-avoidant, and 13% have preoccupied attachment style. Theory of attachment is very useful for understanding the behavior and subjective experiences of children and adults. It is applicable to different contexts (psychotherapy, counseling, education .... The paper proposes further research focused on integration of adult attachment styles and types of object relations measured by Test of object relations (Žvelc, 1998 and Pictorial test of Separation and Individuation (Žvelc, 2003.

    Sleep problems are prevalent among older adults, often persist untreated, and are predictive of health detriments. Given the limitations of conventional treatments, non-pharmacological treatments such as mindfulness-based interventions (MBIs) are gaining popularity for sleep ailments. However, nothing is yet known about the impact of MBIs on sleep in older adults with prodromal sleep disturbances. This article details the design and methodology of a 6-week parallel-group RCT calibrated to test the treatment effect of the Mindful Awareness Practices (MAPs) program versus sleep hygiene education for improving sleep quality, as the main outcome, in older adults with prodromal sleep disturbances. Older adults with current sleep disturbances will be recruited from the urban Los Angeles community. Participants will be randomized into two standardized treatment conditions, MAPs and sleep hygiene education. Each condition will consist of weekly 2-hour group-based classes over the course of the 6-week intervention. The primary objective of this study is to determine if mindfulness meditation practice as engaged through the MAPs program leads to improved sleep quality relative to sleep hygiene education in older adults with prodromal sleep disturbances.

In this paper, we review the clinical features of this relatively common yet underinvestigated condition, with focus on co-occurring neurodevelopmental disorders. Currently available data on the putative pathophysiology of the condition can inform our understanding and guide the diagnostic process and treatment approach. Tinnitus retraining therapy and cognitive behavior therapy have been proposed as the most effective treatment strategies for reducing symptoms; however, current treatment algorithms should be validated in large population studies. At the present stage, competing paradigms see misophonia as a physiological state potentially inducible in any subject, an idiopathic condition (which can present with comorbid psychiatric disorders, or a symptomatic manifestation of an underlying psychiatric disorder. Agreement on the use of standardized diagnostic criteria would be an important step forward in terms of both clinical practice and scientific inquiry. Areas for future research include phenomenology, epidemiology, modulating factors, neurophysiological underpinnings, and treatment trials.
