Tämän diplomityön tavoitteena oli antaa kehittämisehdotuksia, joilla voidaan parantaa rakennustuotealan yrityksen ympäristöjärjestelmien kustannustehokkuutta sekä ympäristöpolitiikkaan liittyvän jatkuvan parantamisen yhtenäistä toteutumista eri toimipaikoilla. Lähtökohtana olivat havainnot siitä, että melko pienissä toimipaikoissa laatu- ja ympäristöasiat kattavan toimintajärjestelmän rakentaminen ja ylläpitäminen vie paljon resursseja. Lisäksi selvitettiin uuden ISO 14001-standardiehdotuksen mahdollisia vaikutuksia käytössä oleviin ympäristöjärjestelmiin. Tutkimusmenetelminä käytettiin eri sertifiointielimille tehtyä haastattelua, toimipaikkojen ympäristövastaaville lähetettyä kyselyä, verkkosivuille kohdistettua kilpailijaseurantaa sekä selvitystä uuden ISO 14001- standardiehdotuksen muutoksista. Eri toimipaikkojen ympäristöjärjestelmien yhdistäminen saman sertifikaatin alle oli kaikkien sertifiointielinten edustajien mielestä hyvä tapa vähentää järjestelmien ulkoisesta valvonnasta aiheutuvia kustannuksia ja parantaa järjestelmien tehokkuutta. Ulkoisten kustannusten aleneminen on noin yksikolmasosa, joka syntyy ensinnäkin sertifikaattimaksujen alenemista ja toisaalta sertifiointipäivien vähenemisestä. Sertifikaattimaksut alenevat, koska yhdistetyssä järjestelmässä sertifikaatteja on vähemmän, ja sertifiointipäivien määrä vähenee, koska yhdistetyn järjestelmän ulkoisessa valvonnassa käytetään otanta -periaatetta. Kilpailijaseurannan osalta havaittiin, että yrityksen verkkosivuilla kerrottiin kilpailijoita paremmin ympäristö- sekä laatujärjestelmistä. Kehitettävää on eri maiden verkkosivujen yhtenäisyydessä ja ympäristö- ja laatupolitiikan esittämisessä. Nämä politiikat tulee olla esillä, koska järjestelmästandardit edellyttävät politiikkojen julkisuutta. Ympäristövastaaville tehdyn kyselyn perusteella havaittiin, että tällä hetkellä toimipaikoilla käytössä olevissa ympäristäjärjestelmissä on eroavuuksia. Syynä tähän on muun muassa järjestelmien eri-ikäisyys, maiden toimipaikkojen erilainen lainsäädäntö sekä erilaiset resurssit. Kehittämistä on erityisesti ympäristönnäkökohtien tunnistamisessa ja merkittävien ympäristönäkökohtien valinnassa, ympäristöjärjestelmän tavoitteissa ja päämäärissä sekä käytettävissä indikaattoreissa. Näiden osalta tulee lisätä koulutusta ja ohjeistusta. Uuden ISO 14001 -standardin muutoksia tarkasteltaessa havaittiin, ettei se aiheuta suuria muutostarpeita nykyisiin ympäristöjärjestelmiin. Standardin suurimmat muutokset ovat tulleet tekstin rakenteeseen, joka on nyt selkeälukuista ja yhteensopivampaa ISO 9001 laatuhallintastandardin kanssa. Standardi painottaa entistä standardia enemmän tuotteista aiheutuvia ympäristönäkökohtia, mutta on muistettava, että sen vaikutukset nykyisiin ympäristöjärjestelmiin tiedetään vasta, kun sitä aletaan tulkita. Tulosten perusteella päädyttiin siihen, että ympäristöjärjestelmien yhdistäminen saman sertifikaatin alle on tehokkain tapa parantaa kustannustehokkuutta sekä parantaa ympäristöpolitiikkaan liittyvää jatkuvaa parantamista. Ulkoisten kustannusten aleminen ei ole tärkein syy järjestelmien yhdistämiseen, koska yhdistämisen alkuvaiheessa se aiheuttaa sisäisten kustannusten lisääntymistä. Jatkossa yhdistämisestä voidaan odottaa myös sisäisten kustannusten säästöjä, koska yhdistäminen vähentää päällekkäistä työtä. Yrityksen ympäristöpolitiikan mukaiseen jatkuvaan parantamiseen järjestelmien yhdistäminen vaikuttaa positiivisesti usealla tavalla, ja tätä voidaan pitää kustannussäästöjä tärkeämpänä syynä sertifikaattien yhdistämiseen. Se yhtenäistää toimintatapoja ja lisää yhteistyötä, mikä vaikuttaa ympäristöpolitiikan yhtenäiseen toteutumiseen.

BACKGROUND: Survival outcomes for patients with glioblastoma remain poor, particularly for patients with unmethylated O(6)-methylguanine-DNA methyltransferase (MGMT) gene promoter. This phase II, randomized, open-label, multicenter trial investigated the efficacy and safety of 2 dose regimens of the selective integrin inhibitor cilengitide combined with standard chemoradiotherapy in patients with newly diagnosed glioblastoma and an unmethylated MGMT promoter. METHODS: Overall, 265 patients were randomized (1:1:1) to standard cilengitide (2000 mg 2×/wk; n = 88), intensive cilengitide (2000 mg 5×/wk during wk 1-6, thereafter 2×/wk; n = 88), or a control arm (chemoradiotherapy alone; n = 89). Cilengitide was administered intravenously in combination with daily temozolomide (TMZ) and concomitant radiotherapy (RT; wk 1-6), followed by TMZ maintenance therapy (TMZ/RT→TMZ). The primary endpoint was overall survival; secondary endpoints included progression-free survival, pharmacokinetics, and safety and tolerability. RESULTS: Median overall survival was 16.3 months in the standard cilengitide arm (hazard ratio [HR], 0.686; 95% CI: 0.484, 0.972; P = .032) and 14.5 months in the intensive cilengitide arm (HR, 0.858; 95% CI: 0.612, 1.204; P = .3771) versus 13.4 months in the control arm. Median progression-free survival assessed per independent review committee was 5.6 months (HR, 0.822; 95% CI: 0.595, 1.134) and 5.9 months (HR, 0.794; 95% CI: 0.575, 1.096) in the standard and intensive cilengitide arms, respectively, versus 4.1 months in the control arm. Cilengitide was well tolerated. CONCLUSIONS: Standard and intensive cilengitide dose regimens were well tolerated in combination with TMZ/RT→TMZ. Inconsistent overall survival and progression-free survival outcomes and a limited sample size did not allow firm conclusions regarding clinical efficacy in this exploratory phase II study.

RESUMO A podridão-olho-de-boi (Cryptosporiosis perennans) e a podridão-branca (Botryosphaeria dothidea) estão entre as principais doenças de verão da macieira no Brasil. O objetivo deste trabalho foi avaliar o efeito de uma película protetora constituída de cera de carnaúba e argilas (Raynox® ), nas doses de 2,5 e 5,0%, na infecção por C. perennans e por B. dothidea em maçãs das cultivares Fuji Standard e Pink Lady. As macieiras foram pulverizadas cinco vezes de dezembro de 2007 a março de 2008, conforme previsão de condições adequadas para ocorrência dos danos e crescimento dos frutos. Na colheita, as maçãs foram inoculadas com os dois patógenos e avaliadas quanto à incidência das podridões. Indiferente à dose, o uso de Raynox® reduziu a incidência da podridão-branca e da podridão-olho-de-boi em 67% e 42% na ‘Fuji Standard’, e 43% e 42% na ‘Pink Lady’, respectivamente. O incremento da dose aumentou a eficiência do produto para o controle da podridão-olho-de-boi. Na dose de 2,5%, o controle da podridão-olho-de-boi foi de 19% e 20%, respectivamente, em maçãs ‘Fuji Standard’ e ‘Pink Lady’, enquanto para as mesmas cultivares, mas com a dose de 5,0%, estes valores foram de 65% e 63%. Mais estudos são necessários para o ajuste de dose e critérios de aplicação para que o protetor solar possa ser recomendado.

The limited armamentarium of active and oral antifungal drugs against emerging non-Aspergillus molds is of particular concern. Current antifungal agents and the new orally available beta-1,3-d-glucan synthase inhibitor SCY-078 were tested in vitro against 135 clinical non-Aspergillus mold isolates. Akin to echinocandins, SCY-078 showed no or poor activity against Mucoromycotina and Fusarium spp. However, SCY-078 was highly active against Paecilomyces variotii and was the only compound displaying some activity against notoriously panresistant Scedosporium prolificans.

Biocuration has become a cornerstone for analyses in biology, and to meet needs, the amount of annotations has considerably grown in recent years. However, the reliability of these annotations varies; it has thus become necessary to be able to assess the confidence in annotations. Although several resources already provide confidence information about the annotations that they produce, a standard way of providing such information has yet to be defined. This lack of standardization undermines the propagation of knowledge across resources, as well as the credibility of results from high-throughput analyses. Seeded at a workshop during the Biocuration 2012 conference, a working group has been created to address this problem. We present here the elements that were identified as essential for assessing confidence in annotations, as well as a draft ontology--the Confidence Information Ontology--to illustrate how the problems identified could be addressed. We hope that this effort will provide a home for discussing this major issue among the biocuration community.

Accurate prediction of mortality following burns is useful as an audit tool, and for providing treatment plan and resource allocation criteria. Common burn formulae (Ryan Score, Abbreviated Burn Severity Index (ABSI), classic and revised Baux) have not been compared with the standard Acute Physiology and Chronic Health Evaluation II (APACHEII) or re-validated in a severely (≥20% total burn surface area) burned population. Furthermore, the revised Baux (R-Baux) has been externally validated thoroughly only once and the pediatric Baux (P-Baux) has yet to be. Using 522 severely burned patients, we show that burn formulae (ABSI, Baux, revised Baux) outperform APACHEII among adults (AUROC increase p<0.001 adults; p>0.5 children). The Ryan Score performs well especially among the most at-risk populations (estimated mortality [90% CI] original versus current study: 33% [26-41%] versus 30.18% [24.25-36.86%] for Ryan Score 2; 87% [78-93%] versus 66.48% [51.31-78.87%] for Ryan Score 3). The R-Baux shows accurate discrimination (AUROC 0.908 [0.869-0.947]) and is well-calibrated. However, the ABSI and P-Baux, although showing high measures of discrimination (AUROC 0.826 [0.737-0.916] and 0.848 [0.758-0.938]) in children), exceedingly overestimates mortality, indicating poor calibration. We highlight challenges in designing and employing scores that are applicable to a wide range of populations.

BACKGROUND & AIMS: The standard liver volume (SLV) is widely used in liver surgery, especially for living donor liver transplantation (LDLT). All the reported formulas for SLV use body surface area or body weight, which can be influenced strongly by the general condition of the patient. METHODS: We analyzed the liver volumes of 180 Japanese donor candidates and 160 Swiss patients with normal livers to develop a new formula. The dataset was randomly divided into two subsets, the test and validation sample, stratified by race. The new formula was validated using 50 LDLT recipients. RESULTS: Without using body weight-related variables, age, thoracic width measured using computed tomography, and race independently predicted the total liver volume (TLV). A new formula: 203.3-(3.61×age)+(58.7×thoracic width)-(463.7×race [1=Asian, 0=Caucasian]), most accurately predicted the TLV in the validation dataset as compared with any other formulas. The graft volume for LDLT was correlated with the postoperative prothrombin time, and the graft volume/SLV ratio calculated using the new formula was significantly better correlated with the postoperative prothrombin time than the graft volume/SLV ratio calculated using the other formulas or the graft volume/body weight ratio. CONCLUSIONS: The new formula derived using the age, thoracic width and race predicted both the TLV in the healthy patient group and the SLV in LDLT recipients more accurately than any other previously reported formulas.

The advent of multiparametric MRI has made it possible to change the way in which prostate biopsy is done, allowing to direct biopsies to suspicious lesions rather than randomly. The subject of this review relates to a computer-assisted strategy, the MRI/US fusion software-based targeted biopsy, and to its performance compared to the other sampling methods. Different devices with different methods to register MR images to live TRUS are currently in use to allow software-based targeted biopsy. Main clinical indications of MRI/US fusion software-based targeted biopsy are re-biopsy in men with persistent suspicious of prostate cancer after first negative standard biopsy and the follow-up of patients under active surveillance. Some studies have compared MRI/US fusion software-based targeted versus standard biopsy. In men at risk with MRI-suspicious lesion, targeted biopsy consistently detects more men with clinically significant disease as compared to standard biopsy; some studies have also shown decreased detection of insignificant disease. Only two studies directly compared MRI/US fusion software-based targeted biopsy with MRI/US fusion visual targeted biopsy, and the diagnostic ability seems to be in favor of the software approach. To date, no study comparing software-based targeted biopsy against in-bore MRI biopsy is available. The new software-based targeted approach seems to have the characteristics to be added in the standard pathway for achieving accurate risk stratification. Once reproducibility and cost-effectiveness will be verified, the actual issue will be to determine whether MRI/TRUS fusion software-based targeted biopsy represents anadd-on test or a replacement to standard TRUS biopsy.

Payment Card Industry Data Security Standard (PCI DSS) on korttiyhtiöiden kehittämä kansainvälinen tietoturvastandardi, jonka tarkoituksena on parantaa kortinhaltijoiden tietoja käsittelevien järjestelmien tietoturvaa. Standardissa määritellään vaatimukset tietojen turvalliselle tallennukselle ja käsittelylle, testaus- ja tarkastusmenetelmät sekä tarkastusvaatimukset ja tarkastuksia suorittavien tahojen sertifiointi. Standardi koskee kaikkia standardin hyväksyneiden maksukorttiyhtiöiden korttitietoja käsitteleviä tahoja. Standardin ylläpitämisestä ja kehittämisestä vastaa maksukorttiyhtiöiden perustama PCI Security Standards Council -toimielin. Syyskuussa 2006 toimielin julkaisi standardista version 1.1, joka on edelleen viimeisin versio. Tässä diplomityössä selvitettiin PCI DSS -standardin asettamat vaatimukset kortinhaltijoiden tietoja käsitteleville tahoille. Lisäksi tutkittiin mahdollisuuksia toteuttaa yksi standardin vaatimuksista, kortinhaltijoiden tietojen suojaaminen, esimerkkijärjestelmässä. Kyseinen järjestelmä on kehitetty IBM System i -palvelinympäristöön käyttäen RPG-ohjelmointikieltä.

Objective: To summarise and critically evaluate the evidence informing the provision of standard care practices and psychosocial interventions following stillbirth. Background: Stillbirth is increasingly recognised as a significant bereavement experience with the potential to cause substantial psychological distress for parents. Standard care practices and psychosocial interventions to support parents have undergone dramatic changes, with limited basis in evidence. Methods: A systematic narrative review was conducted of quantitative studies examining interventions designed to reduce psychological distress in parents following the loss of a stillborn baby. Results: Twenty-five studies met the inclusion criteria for the review. Substantial methodological weaknesses were identified among reviewed studies, including small and heterogeneous loss samples, weak study designs and lack of clarity in reported methods and outcomes. Inadequate replication of many findings substantially limits the generalisability of the evidence. Conclusion: Tentative evidence was found for the provision of mementoes of the baby and information regarding the cause of the loss, support group attendance, and cognitive behavioural interventions for parents identified with clinical levels of distress. Contradictory findings for the impact of contact with the baby prevent the formation of clear conclusions for this practice. Due to the methodological weaknesses prevalent in the research identified, the current evidence base is not considered sufficiently able to reliably inform care practices and intervention approaches. High-quality research evidence in this field is urgently required.

QUESTIONS UNDER STUDY: Studies from several countries (Scandinavia, United Kingdom) report that general practitioners (GPs) experience problems in sickness certification. Our study explored views of Swiss GPs towards sickness certification, their practice and experience, professional skills and problematic interactions with patients. METHODS: We conducted an online survey among GPs throughout Switzerland, exploring behaviour of physicians, patients and employers with regard to sickness certification; GPs' views about sickness certification; required competences for certifying sickness absence, and approaches to advance their competence. We piloted the questionnaire and disseminated it through the networks of the five Swiss academic institutes for primary care. RESULTS: We received 507 valid responses (response rate 50%). Only 43/507 GPs experienced sickness certification as problematic per se, yet 155/507 experienced problems in sickness certification at least once a week. The 507 GPs identified estimating a long-term prognosis about work capacity (64%), handling conflicts with patients (54%), and determining the reduction of work capacity (42%) as problematic. Over 75% would welcome special training opportunities, e.g., on sickness certifications during residency (93%), in insurance medicine (81%), and conflict management (80%). CONCLUSION: Sickness certification as such does not present a major problem to Swiss GPs, which contrasts with the experience in Scandinavian countries and in the UK. Swiss GPs did identify specific tasks of sickness certification as problematic. Training opportunities on sick-leave certification and insurance medicine in general were welcomed.

The directional consistency and skew-symmetry statistics have been proposed as global measurements of social reciprocity. Although both measures can be useful for quantifying social reciprocity, researchers need to know whether these estimators are biased in order to assess descriptive results properly. That is, if estimators are biased, researchers should compare actual values with expected values under the specified null hypothesis. Furthermore, standard errors are needed to enable suitable assessment of discrepancies between actual and expected values. This paper aims to derive some exact and approximate expressions in order to obtain bias and standard error values for both estimators for round-robin designs, although the results can also be extended to other reciprocal designs.
