Background: Research indicates that Posttraumatic stress disorder(PTSD) has an extensive impact on family relationships. Nevertheless, there is a dearth of empirically supported interventions addressing family functioning and PTSD. In the Netherlands, it is considered good clinical practice to offer multi-family therapy(MFT) to veteran and refugee families. MFT for traumatized families aims to address the dysfunctional family patterns that have evolved to address the consequences with ***: The aim of this study is to generate a common framework for the practical impact and active ingredients of MFT in families confronted with trauma. The Delphi method was used to study the expert opinion of 11 therapists in Dutch expert trauma ***: The results indicate that MFT is a promising treatment for families dealing with the consequences of trauma. According to experts, positive outcomes include an increased understanding between family members,particularly visible in the de-escalation of conflicts within the family, and improved parenting. One explanation for the effectiveness of MFT with these target groups is its defining feature of therapy with several ***: The findings support the importance of considering family relationships and the family context in interventions for traumatized individuals.

How do stream processes affect hazard exposure on alluvial fans? Insights from an experimental study

Journal of Mountain Science 2020年第4期17卷 753-772页

Alluvial fans are among the most privileged settlement areas in many mountain regions. These landforms are particularly dynamic being episodically affected by distributary processes generated by extreme flood events. Addressing risk assessment entails determining hazard exposure and unravelling how it might be related to process loading and to process dynamics once the flow becomes unconfined on the surface of alluvial fans. By following a ‘similarity of process concept’, rather than by attempting to scale a real-world prototype, we performed a set of 72 experimental runs on an alluvial fan model. Thereby, we considered two model layouts, one without a guiding channel and featuring a convex shape and the other one with a guiding channel, a bridge, and inclined but planar overland flow areas as to mirror an anthropic environment. Process magnitude and intensity parameters were systematically varied, and the associated biphasic distributary processes video recorded. For each experiment, the exposure was detected by mapping the exposed area in a GIS, thereby discerning between areas exposed to biphasic flows and the associated depositional phenomena or to the liquid flow phase only. Our results reveal that total event volume, sediment availability and stream power in the feeding channel, as well as depositional effects, avulsion, and channelization on the alluvial fan concur to determine the overall exposure. Stream process loading alone, even when rigorously defined in terms of its characterizing parameters, is not sufficient to exhaustively determine exposure. Hence, further developing reliable biphasic simulation models for hazard assessment on settled alluvial fans is pivotal.

Biomarkers for pancreatic cancer:Recent achievements in proteomics and genomics through classical and multivariate statistical methods

World Journal of Gastroenterology 2014年第37期20卷 13325-13342页

作者： Emilio Marengo elisa Robotti Department of Sciences and Technological Innovation University of Piemonte Orientale

Pancreatic cancer(PC) is one of the most aggressive and lethal neoplastic diseases. A valid alternative to the usual invasive diagnostic tools would certainly be the determination of biomarkers in peripheral fluids to provide less invasive tools for early diagnosis. Nowadays, biomarkers are generally investigated mainly in peripheral blood and tissues through high-throughput omics techniques comparing control vs pathological samples. The results can be evaluated by two main strategies:(1) classical methods in which the identification of significant biomarkers is accomplished by monovariate statistical tests where each biomarker is considered as independent from the others; and(2) multivariate methods, taking into consideration the correlations existing among the biomarkers themselves. This last approach is very powerful since it allows the identification of pools of biomarkers with diagnostic and prognostic performances which are superior to single markers in terms of sensitivity, specificity and robustness. Multivariate techniques are usually applied with variable selection procedures to provide a restricted set of biomarkers with the best predictive ability; however, standard selection methods are usually aimed at the identification of the smallest set of variables with the best predictive ability and exhaustivity is usually neglected. The exhaustive search for biomarkers is instead an important alternative to standard variable selection since it can provide information about the etiology of the pathology by producing a comprehensive set of markers. In this review, the most recent applications of the omics techniques(proteomics, genomics and metabolomics) to the identification of exploratory biomarkers for PC will be presented with particular regard to the statistical methods adopted for their identification. The basic theory related to classical and multivariate methods for identification of biomarkers is presented and then, the most recent applications in this f

Regulation mechanisms of endocrine disruptors on vasodilation andvasoconstriction: Insights from ex vivo models

Cardiovascular diseases (CVD) are one of the leading causes of death worldwide. The knowledge andunderstanding of CVD are based on the study of vascular physiology and how the smooth muscle cells and tissuesperform their different functions. Exposure to endocrine disruptors (EDCs), such as phytoestrogens, polycyclicaromatic hydrocarbons, flame retardants, plasticizers, pesticides, and cosmetics, is an integral and fundamental part ofhuman exposure. Humans are exposed to EDCs by multiple pathways including air, food, water, and consumerproducts. However, this exposure can lead to several adverse effects on human health, including on the cardiovascular(CV) system. The negative impact that EDC toxicity has on human CV health is a serious problem that must not beoverlooked. In this point of view, we proposed the use of the human umbilical artery as a human model to study thedirect effects of EDCs on the vascular level. Several works where these cells were directly exposed to EDC’s werepresented to highlight this well-established model as a great strategy to be used. In the future, we emphasize the needto continue to carry out different investigations using HUA to unveil and understand the vascular toxicity of EDCsand improve human CV health.

Multivariate analysis to predict letrozole efficacy in improving sperm count of non-obstructive azoospermic and cryptozoospermic patients： a pilot study

Asian Journal of Andrology 2013年第6期15卷 806-811,I0009-I0010页

作者： Giorgio Cavallini Giulio Biagiotti elisa Bolzon Andros-ltalia Outpatient Clinic of Ferrara Ferrara 44121 Italy Androsqtalia Outpatient Clinic of Perugia PeruRia 06128 Italy

We tested the hypothesis that letrozole increases sperm count in non-obstructive azoospermic or cryptozoospermic patients with a testosterone （T）/17-beta-2-oestradiol （E2） ratio 〈 10. Forty-six patients with no chromosomal aberrations were randomized into two groups： 22 received letrozole 2.5 mg per day for 6 months （Group 1：6 azoospermic＋ 16 cryptozoospermic patients）, while 24 received a placebo （Group 2：5 azoospermic＋19 cryptozoospermic patients）. The following data were collected： two semen analyses, clinical history, scrotal Duplex scans, body mass index （BMI）, Y microdeletion, karyotype and cystic fibrosis screens and follicle-stimulating hormone （FSH）, luteinizing hormone （LH）, E2, T and prolactin levels. Both before and after letrozole or placebo administration, the patients underwent two semen analyses and hormonal assessments. The differences were evaluated using the Mann-Whitney Utest. The relationships between sperm concentration after letrozole administration with respect to FSH, TIE2 ratio, bilateral testicle volume and BMI before letrozole administration were assessed using multivariate analysis. The side effects were assessed using the chi-square test. Group 1 had sperm concentration （medians： 400-1.290× 10^6 ml^-1; P〈0.01） and motility （medians： class A from 2% to 15%; P〈0.01）, FSH, LH and T significantly increased, while Group 2 did not. E2 levels diminished significantly in Group 1, but not in Group 2. Eight patients in Group 1 demonstrated side effects, whereas no patient side effects were observed in Group 2. The sperm concentration after letrozole administration is inversely related to TIE2, FSH and BMI; a direct relationship emerged between sperm concentration and testicular volume.
