Better winter road weather information saves money, time, lives and the environment

Weather service systems that collect, refine and distribute information to road users and to network and maintenance operators can generate significant benefits to stakeholders and society. For maintenance operators improved efficiency through timely reactions, smaller amounts of de-icing materials and better personnel utilization offer clear potential for reduced costs. In the future, better weather models will result in more accurate longer-term forecasts thus increasing the potential for benefits. New technology enables new kinds of services (e.g. decision support systems). This paper provides a structured view of the impacts of weather information services to different stakeholders

Ripening Stage Effects on Mechanical and Functional Properties of Pastry Filled with Sweet Cherries (Prunus avium, ‘Ferrovia’ Cultivar)

Sweet cherry is a precious fruit for the wealth of minerals, vitamins and other important protecting, detoxifying and purifying principles. These features make it interesting in terms of nutritional and health point of view. Many studies have demonstrated the beneficial effects on prevention of cardiovascular and articular diseases, due to anti-inflammatory and analgesic action of sweet cherry. However, because of its seasonality, it needs technological treatments to be preserved (jam, puree or semi-finished products for pastry), that could compromise its nutritional quality. The aim of this work was to study the effects of ripening stage and technological tratments on mechanical and functional properties of pastries filled with sweet cherries during storage at room temperature. Results showed that the different ripeness of cherries influenced the mechanical properties of samples: pastries filled with overripe cherries resulted more hard (97 vs. 79 N), less cohesive (0.19 vs. 0.25) and springy (6.4 vs. 8.5 mm) than medium harvest cherries. The antioxidant capacity of medium harvest sweet cherries did not change after both technological treatments and storage (0.93 vs. 0.89 TEAC micromol/g dry basis). These results highlight the importance of ripening stage of processed fruit used as ingredient in complex food in order to obtain a product with good functional and quality properties

(-)-tarchonanthuslactone exerts a blood glucose-increasing effect in experimental type 2 diabetes mellitus

A number of studies have proposed an anti-diabetic effect for tarchonanthuslactone based on its structural similarity with caffeic acid, a compound known for its blood glucose-reducing properties. However, the actual effect of tarchonanthuslactone on blood glucose level has never been tested. Here, we report that, in opposition to the common sense, tarchonanthuslactone has a glucose-increasing effect in a mouse model of obesity and type 2 diabetes mellitus. The effect is acute and non-cumulative and is present only in diabetic mice. In lean, glucose-tolerant mice, despite a slight increase in blood glucose levels, the effect was not significant.A number of studies have proposed an anti-diabetic effect for tarchonanthuslactone based on its structural similarity with caffeic acid, a compound known for its blood glucose-reducing properties.

Potentials and limitations of NFIs and remote sensing in the assessment of harvest rates: a reply to Breidenbach et al.

AbstractThe timely and accurate monitoring of forest resources is becoming of increasing importance in light of the multi-functionality of these ecosystems and their increasing vulnerability to climate change. Remote sensing observations of tree cover and systematic ground observations from National Forest Inventories (NFIs) represent the two major sources of information to assess forest area and use. The specificity of two methods is calling for an in-depth analysis of their strengths and weaknesses and for the design of novel methods emerging from the integration of satellite and surface data. On this specific debate, a recent paper by Breidenbach et al. published in this journal suggests that the detection of a recent increase in EU forest harvest rate—as reported in Nature by Ceccherini et al.—is largely due to technical limitations of satellite-based mapping. The article centers on the difficulty of the approaches to estimate wood harvest based on remote sensing. However, it does not discuss issues with the robustness of validation approaches solely based on NFIs. Here we discuss the use of plot data as a validation set for remote sensing products, discussing potentials and limitations of both NFIs and remote sensing, and how they can be used synergistically. Finally, we highlight the need to collect in situ data that is both relevant and compatible with remote sensing products within the European Union

Subjective Well-Being Under Neuroleptics Scale short form (SWN-K):Reliability and validity in an Estonian speaking sample

BACKGROUND: The Subjective Well-Being Under Neuroleptic Treatment Scale short form (SWN-K) is a self-rating scale developed to measure mentally ill patients' well-being under the antipsychotic drug treatment. This paper reports on adaptation and psychometric properties of the instrument in an Estonian psychiatric sample. METHODS: In a naturalistic study design, 124 inpatients or outpatients suffering from the first psychotic episode or chronic psychotic illness completed the translated SWN-K instrument. Item content analysis, internal consistency analysis, exploratory principal components analysis, and confirmatory factor analysis were used to construct the Estonian version of the SWN-K (SWN-K-E). Additionally, socio-demographic and clinical data, observer-rated psychopathology, medication side effects, daily antipsychotic drug dosages, and general functioning were assessed at two time points, at baseline and after a 29-week period; the associations of the SWN-K-E scores with these variables were explored. RESULTS: After having selected 20 items for the Estonian adaptation, the internal consistency of the total SWN-K-E was 0.93 and the subscale consistencies ranged from 0.70 to 0.80. Good test–retest reliabilities were observed for the adapted scale scores, with the correlation of the total score over about 6 months being r = 0.70. Confirmatory factor analysis replicated the presence of a higher-order factor (general well-being) and five first-order factors (mental functioning, physical functioning, social integration, emotional regulation, and self-control); the model fitted the data well. The results indicated a moderate-high correlations r = 0.54 between the SWN-K-E total score and the evaluation how satisfied patients were with their lives in generally. No significant correlations were found between the overall subjective well-being score and age, severity of the psychopathology, drug adverse effects, or prescribed drug dosage. CONCLUSION: Taken together, the results demonstrated that the Estonian version of the SWN-K is a reliable and valid instrument with psychometric properties similar to the original English version. The potential uses of the scale in both research and clinical settings are considered

Baseline serum TSH levels predict the absence of thyroid dysfunction in cancer patients treated with immunotherapy

Purpose Immunotherapy against immune checkpoints has significantly improved survival both in metastatic and adjuvant setting in several types of cancers. Thyroid dysfunction is the most common endocrine adverse event reported. Patients who are at risk of developing thyroid dysfunction remain to be defined. We aimed to identify predictive factors for the develop- ment of thyroid dysfunction during immunotherapy. Methods This is a retrospective study including a total of 68 patients who were treated with immune checkpoint inhibi- tors (ICIs) for metastatic or unresectable advanced cancers. The majority of patients were treated with anti-PD1 drugs in monotherapy or in combination with anti-CTLA4 inhibitors. Thyroid function and anti-thyroid antibodies, before starting immunotherapy and during treatment, were evaluated. Thyroid ultrasound was also performed in a subgroup of patients at the time of enrolment in the study. Results Eleven out of 68 patients (16.1%) developed immune-related overt thyroid dysfunction. By ROC curve analysis, we found that a serum TSH cut-off of 1.72 mUI/l, at baseline, had a good diagnostic accuracy in identifying patients without overt thyroid dysfunction (NPV = 100%, p = 0.0029). At multivariate analysis, both TSH and positive anti-thyroid antibod- ies (ATAbs) levels, before ICIs treatment, were independently associated with the development of overt thyroid dysfunction during immunotherapy (p = 0.0001 and p = 0.009, respectively). Conclusions Pre-treatment serum TSH and ATAbs levels may help to identify patients at high risk for primary thyroid dysfunction. Our study suggests guidance for an appropriate timely screening and for a tailored management of thyroid dysfunctions in patients treated with ICIs
