Harmonization of immune biomarker assays for clinical studies.

Assays that measure a patient's immune response play an increasingly important role in the development of immunotherapies. The inherent complexity of these assays and independent protocol development between laboratories result in high data variability and poor reproducibility. Quality control through harmonization--based on integration of laboratory-specific protocols with standard operating procedures and assay performance benchmarks--is one way to overcome these limitations. Harmonization guidelines can be widely implemented to address assay performance variables. This process enables objective interpretation and comparison of data across clinical trial sites and also facilitates the identification of relevant immune biomarkers, guiding the development of new therapies.

Estimating the Impact on Efficiency of the Adoption of a Voluntary Environmental Standard: An Empirical Study of the Global Copper Mining Industry

This paper uses data on the world's copper mining industry to measure the impact on efficiency of the adoption of the ISO 14001 environmental standard. Anecdotal and case study literature suggests that firms are motivated to adopt this standard so as to achieve greater efficiency through changes in operating procedures and processes. Using plant level panel data from 1992-2007 on most of the world's industrial copper mines, the study uses stochastic frontier methods to investigate the effects of ISO adoption. The variety of models used in this study find that adoption either tends to improve efficiency or has no impact on efficiency, but no evidence is found that ISO adoption decreases efficiency.

Report of an audit of child protection research in Ireland 1990-2009.

A total of 190 research documents were identified in line with the criteria agreed between the researchers and the CAAB, and are included in the audit. The key findings from the analysis of the audit are as follows:    - Research identified in the audit has tended to focus on child protection and the child protection system generally, as well as sexual abuse. This research has primarily been undertaken by clinicians and academics, and spans across sectors.   - Over half, (110 or 58%) of the research falls under the heading of policy/practice reviews/analysis. This is further reflected in the fact that the research most commonly focused on operating procedures, followed by practice issues and the policy framework, both in studies with a single focus and those with multiple foci.   - The most common type of publication was peer reviewed article (74 or 39%), with commissioned research accounting for just 7% (13). This is in line with the findings that 68% (128) of commissioning/publishing bodies and 74% (139) of research bodies were in the academic sector.   - The research published and/or commissioned by the statutory sector follows the pattern found in the audit generally, with the most common type of study being policy/practice review/analysis (27 or 48%) and the most common focus being operating procedures (22 or 39%).   - Information sources rarely incorporated primary research with children, with only 14 studies (8%) citing direct contact with children and young people. Information on children was more commonly gathered from case files, professionals and family members.   - The topics covered in the identified research were very wide-ranging but closely related to the primary subject area (type of abuse) and the sector in which the research was located.   One conclusion stated that: There is a shortage of child protection-focused research on the factors that cause and perpetuate child abuse, such as homelessness, addiction, parental mental illness and domestic violence. The need for material on these areas is demonstrated by the nature and scale of reports to the child protection system and the removal of some children from their families into out of home care as a result of the above mentioned adversities.This resource was contributed by The National Documentation Centre on Drug Use.

Perspectivas de salud ambiental en la investigación de brotes epidémicos asociados con una zona de abastecimiento de aguas de consumo humano.

Introduction. The purpose of this work was studied the magnitude, possible causes and contributing environmental factors in the waterbourne outbreaks appearance, in the performance area of the locality of Benaoján (Town of Málaga. Spain). Material/Methods. Analysis of the potability of the water and disinfection controls. Evaluation of the fulfillment of the quality of the drinking water and sanitary technical requirements of water supplies, pursuant to the Spanish regulation on public consumption waters. Results. We have been accomplished 110 potability analysis, proving that 13,4% of the samples do not comply with the potability criteria of the water. It were practiced 647 controls of disinfection, of those which 53% resulted not accordant. The design of the supply net is of the branching type and at least presents 30 blind branches, points where the water remains stagnant. The municipal waters service doesn´t make analytics controls of the quality of the water neither has implanted Standard Operating Procedures (SOPs) of the facilities of the supply. Discussion. Environmental research suggests that the public water supply net is a source of infection, problem related to the epidemic outbreaks appearance. Because of this the water consumption not treaty must be avoided.

EULAR recommendations for the management of large-vessel vasculitis.

Objectives: To develop European League Against Rheumatism (EULAR) recommendations for the management of large vessel vasculitis. Methods: An expert group (10 rheumatologists, 3 nephrologists, 2 immunolgists, 2 internists representing 8 European countries and the USA, a clinical epidemiologist and a representative from a drug regulatory agency) identified 10 topics for a systematic literature search through a modified Delphi technique. In accordance with standardised EULAR operating procedures, recommendations were derived for the management of large vessel vasculitis. In the absence of evidence, recommendations were formulated on the basis of a consensus opinion. Results: Seven recommendations were made relating to the assessment, investigation and treatment of patients with large vessel vasculitis. The strength of recommendations was restricted by the low level of evidence and EULAR standardised operating procedures. Conclusions: On the basis of evidence and expert consensus, management recommendations for large vessel vasculitis have been formulated and are commended for use in everyday clinical practice.

Turvallisuustoimintojen käyttö ydinvoimalaitoksilla

Tässä diplomityössä tarkastellaan turvallisuustoiminto-käsitteen määrittelyä ja käyttöä osana ydinvoimalaitosten turvallisuuden varmistamista. Työssä kuvataan paine- ja kiehutusvesilaitosten toiminnan yleispiirteet, sekä Teollisuuden Voima Oy:n (TVO) laitosten Olkiluoto 1 & 2 sekä Olkiluoto 3 tarkempi turvallisuustoiminta turvallisuusjärjestelmien ja -automaation osalta. Työssä esitellään eräs tapa määrittää turvallisuustoimintoja. Malli perustuu hierarkkiseen rakenteeseen, jossa ylimpänä ovat laitostason turvallisuustoiminnot ja alimpana turvallisuustoimintoihin osallistuvien laitteiden ja niiden osien toiminnot. Turvallisuustoimintoja on mahdollista käyttää ydinvoimalaitoksen turvallisuusluokituksen tekemiseen ja perustelemiseen. Turvallisuustoiminto kertoo suoraan luokiteltavan kohteen turvallisuusmerkityksen. Kohteen turvallisuusmerkityksen selvittäminen, eli liittäminen turvallisuustoimintoon, voi olla vaikeaa. Turvallisuustoimintoja on myös mahdollista käyttää laitoksen turvallisuusautomaation riittävän varmistamisen (mm. redundanttisuus, diversiteetti ja erotus) osoittamiseen erityisesti ohjelmoitavan automaation yhteydessä. Turvallisuustoimintoja voidaan hyödyntää laitoksen hätätilanneohjeiden kehittämisessä ja myös laitoksenmuun turvallisuusdokumentaation selkeyttämisessä. Työn tuloksena kehitettiin käyville laitoksille (OL1 & 2) aikaisempaa kattavammat turvallisuustoiminnot. Lisäksi tarkasteltiin rakenteilla olevalle laitokselle (OL3) määriteltyjä turvallisuustoimintoja.

Effect of Noncondensable Gases on Circulation of Primary Coolant in Nuclear Power Plants in Abnormal Situations

The present study focuses on two effects of the presence of a noncondensable gas on the thermal-hydraulic behavior of thecoolant of the primary circuit of a nuclear reactor in the VVER-440 geometry inabnormal situations. First, steam condensation with the presence of air was studied in the horizontal tubes of the steam generator (SG) of the PACTEL test facility. The French thermal-hydraulic CATHARE code was used to study the heat transfer between the primary and secondary side in conditions derived from preliminary experiments performed by VTT using PACTEL. In natural circulation and single-phase vapor conditions, the injection of a volume of air, equivalent to the totalvolume of the primary side of the SG at the entrance of the hot collector, did not stop the heat transfer from the primary to the secondary side. The calculated results indicate that air is located in the second half-length (from the mid-length of the tubes to the cold collector) in all the tubes of the steam generator The hot collector remained full of steam during the transient. Secondly, the potential release of the nitrogen gas dissolved in the water of the accumulators of the emergency core coolant system of the Loviisa nuclear power plant (NPP) was investigated. The author implemented a model of the dissolution and release ofnitrogen gas in the CATHARE code; the model created by the CATHARE developers. In collaboration with VTT, an analytical experiment was performed with some components of PACTEL to determine, in particular, the value of the release time constant of the nitrogen gas in the depressurization conditions representative of the small and intermediate break transients postulated for the Loviisa NPP. Such transients, with simplified operating procedures, were calculated using the modified CATHARE code for various values of the release time constant used in the dissolution and release model. For the small breaks, nitrogen gas is trapped in thecollectors of the SGs in rather large proportions. There, the levels oscillate until the actuation of the low-pressure injection pumps (LPIS) that refill the primary circuit. In the case of the intermediate breaks, most of the nitrogen gas is expelled at the break and almost no nitrogen gas is trapped in the SGs. In comparison with the cases calculated without taking into account the release of nitrogen gas, the start of the LPIS is delayed by between 1 and 1.75 h. Applicability of the obtained results to the real safety conditions must take into accountthe real operating procedures used in the nuclear power plant.

Tuotantolaitteiden kvalifiointi ja prosessin validointi GMP-tuotantoa varten

GMP-säädösten mukaan aktiivisten lääkeaineiden, kriittisten lääkeaineintermediaattien ja lääkeapuaineiden valmistusprosessit pitää validoida. Validointityöhön kuuluu oleellisesti tuotantolaitteiden kvalifiointi ja prosessin validointi. Käytännössä tuotantolaitteiden kvalifiointi toteutetaan tekemällä laitteille suunnitelmien tarkastus (DQ), asennus- ja käyttöönottotarkastus (IQ), toiminnan testaus (OQ) sekä suorituskykytestit (PQ). Tuotantolaitteiden kvalifiointiin kuuluu myös laitteiden asianmukaisten kalibrointi-, kunnossapito- ja puhdistusohjeiden sekä työ- ja toimintaohjeiden (SOP:ien) laatiminen. Prosessin validoinnissa laaditaan dokumentoidut todisteet siitä, että prosessi toimii vakaasti ja tuotteelle asetetut vaatimukset täyttyvät johdonmukaisesti. GMP-tuotantolaitteiden kvalifiointiin ja lääkevalmistusprosessin validointiin on laadittu erilaisia GMP-säädöksiä noudattavia yleisiä validointiohjeita, kuten PIC/S:n ja FDA:n ohjeet kvalifioinnista ja validoinnista. IVT/SC on laatinut yksiselitteiset validointistandardit validointityön selventämiseksi. Validoinnin tilastolliseen tarkasteluun on käytettävissä GHTF:n laatimat tilastolliset validointimenetelmät. Yleensä tuotantolaitteiden kvalifiointi ja prosessin validointi tehdään ennen lääkevalmisteen kaupallisen tuotannon aloittamista. Kvalifiointi- ja validointityö voidaan tehdä kuitenkin myös tuotannon yhteydessä (konkurrentisti) tai retrospektiivisesti käyttäen hyväksi valmistettujen tuotantoerien prosessitietoja. Tässä työssä laadittiin Kemira Fine Chemicals Oy:n Kokkolan GMP-tuotantolinjan lääkeaineintermediaattiprosessin validoinnin yleissuunnitelma (VMP), joka sisältää sekä tuotantolaitteiden kvalifiointisuunnitelman että prosessin validointisuunnitelman. Suunnitelmissa huomioitiin tuotantolaitteiden aikaisempi käyttö muuhun hienokemikaalituotantoon ja tuotantolinjan muuttaminen GMP-vaatimusten mukaiseksi. Työhön kuului myös tuotantolaitteiden kvalifiointityön tekeminen laaditun suunnitelman mukaisesti.

An innovative and shared methodology for event reconstruction using images in forensic science

This study presents an innovative methodology for forensic science image analysis for event reconstruction. The methodology is based on experiences from real cases. It provides real added value to technical guidelines such as standard operating procedures (SOPs) and enriches the community of practices at stake in this field. This bottom-up solution outlines the many facets of analysis and the complexity of the decision-making process. Additionally, the methodology provides a backbone for articulating more detailed and technical procedures and SOPs. It emerged from a grounded theory approach; data from individual and collective interviews with eight Swiss and nine European forensic image analysis experts were collected and interpreted in a continuous, circular and reflexive manner. Throughout the process of conducting interviews and panel discussions, similarities and discrepancies were discussed in detail to provide a comprehensive picture of practices and points of view and to ultimately formalise shared know-how. Our contribution sheds light on the complexity of the choices, actions and interactions along the path of data collection and analysis, enhancing both the researchers' and participants' reflexivity.

Mercury analysis in hair: comparability and quality assessment within the transnational COPHES/DEMOCOPHES project

Human biomonitoring (HBM) is an effective tool for assessing actual exposure to chemicals that takes into account all routes of intake. Although hair analysis is considered to be an optimal biomarker for assessing mercury exposure, the lack of harmonization as regards sampling and analytical procedures has often limited the comparison of data at national and international level. The European-funded projects COPHES and DEMOCOPHES developed and tested a harmonized European approach to Human Biomonitoring in response to the European Environment and Health Action Plan. Herein we describe the quality assurance program (QAP) for assessing mercury levels in hair samples from more than 1800 mother-child pairs recruited in 17 European countries. To ensure the comparability of the results, standard operating procedures (SOPs) for sampling and for mercury analysis were drafted and distributed to participating laboratories. Training sessions were organized for field workers and four external quality-assessment exercises (ICI/EQUAS), followed by the corresponding web conferences, were organized between March 2011 and February 2012. ICI/EQUAS used native hair samples at two mercury concentration ranges (0.20-0.71 and 0.80-1.63) per exercise. The results revealed relative standard deviations of 7.87-13.55% and 4.04-11.31% for the low and high mercury concentration ranges, respectively. A total of 16 out of 18 participating laboratories the QAP requirements and were allowed to analyze samples from the DEMOCOPHES pilot study. Web conferences after each ICI/EQUAS revealed this to be a new and effective tool for improving analytical performance and increasing capacity building. The procedure developed and tested in COPHES/DEMOCOPHES would be optimal for application on a global scale as regards implementation of the Minamata Convention on Mercury.
