Abstract
BACKGROUND Emotional disorders (depression and anxiety disorders) are highly prevalent mental health problems. Although evidence showing the effectiveness of disorder-specific treatments exists, high comorbidity rates among emotional disorders limit the utility of these protocols. This has led some researchers to focus their interest on transdiagnostic interventions, a treatment perspective that might be more widely effective across these disorders. Also, the current way of delivering treatments makes it difficult provide assistance to all of the population in need. The use of the Internet in the delivery of evidence-based treatments may help to disseminate treatments among the population. In this study, we aim to test the effectiveness of EmotionRegulation, a new transdiagnostic Internet-based protocol for unipolar mood disorders, five anxiety disorders (panic disorder, agoraphobia, social anxiety disorder, generalized anxiety disorder and anxiety disorder not otherwise specified), and obsessive-compulsive disorder in comparison to treatment as usual as provided in Spanish public specialized mental health care. We will also study its potential impact on basic temperament dimensions (neuroticism/behavioral inhibition and extraversion/behavioral activation). Expectations and opinions of patients about this protocol will also be studied. METHODS/DESIGN The study is a randomized controlled trial. 200 participants recruited in specialized care will be allocated to one of two treatment conditions: a) EmotionRegulation or b) treatment as usual. Primary outcome measures will be the BAI and the BDI-II. Secondary outcomes will include a specific measure of the principal disorder, and measures of neuroticism/behavioral inhibition and extraversion/behavioral activation. Patients will be assessed at baseline, post-treatment, and 3- and 12-month follow-ups. Intention to treat and per protocol analyses will be performed. DISCUSSION Although the effectiveness of face-to-face transdiagnostic protocols has been investigated in previous studies, the number of published transdiagnostic Internet-based programs is still quite low. To our knowledge, this is the first randomized controlled trial studying the effectiveness of a transdiagnostic Internet-based treatment for several emotional disorders in public specialized care. Combining both a transdiagnostic approach with an Internet-based therapy format may help to decrease the burden of mental disorders, reducing the difficulties associated with disorder-specific treatments and facilitating access to people in need of treatment. Strengths and limitations are discussed. TRIAL REGISTRATION ClinicalTrials.gov NCT02345668 . Registered 27 July 2015.

Abstract
OBJECTIVE College represents a window of opportunity to reach the sizeable number of cigarette smokers who are vulnerable to lifelong smoking. The underutilization of typical cessation programs suggests the need for novel and more engaging approaches for reaching college smokers. The aim of the present study was to test the efficacy of a dissonance-enhancing, Web-based experiential intervention for increasing smoking cessation motivation and behavior. METHOD We used a 4-arm, randomized design to examine the efficacy of a Web-based, experiential smoking intervention (Web-Smoke). The control conditions included a didactic smoking intervention (Didactic), a group-based experiential intervention (Group), and a Web-based nutrition experiential intervention (Web-Nutrition). We recruited 341 college smokers. Primary outcomes were motivation to quit, assessed immediately postintervention, and smoking abstinence at 1 and 6 months following the intervention. RESULTS As hypothesized, the Web-Smoke intervention was more effective than control groups in increasing motivation to quit. At 6-month follow-up, the Web-Smoke intervention produced higher rates of smoking cessation than the Web-Nutrition control intervention. Daily smoking moderated intervention outcomes. Among daily smokers, the Web-Smoke intervention produced greater abstinence rates than both the Web-Nutrition and Didactic control conditions. CONCLUSION Findings demonstrate the efficacy of a theory-based intervention delivered over the Internet for increasing motivation to quit and smoking abstinence among college smokers. The intervention has potential for translation and implementation as a secondary prevention strategy for college-aged smokers. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

Abstract
OBJECTIVE Total parenteral nutrition is commonly used in neonates' intensive care units for nutritional support of preterm neonates. Adequacy and safety of parenteral nutrition support are amongst the major concerns of neonates' therapy. Parenteral nutrition prescription in Greek hospitals is not based on standardized protocols, thus resulting in wide diversity of formulations. In this study, the results of utilization of standardized computerized parenteral nutrition protocols and regimens for neonates are compared to the results of protocols and regimens prescribed by individual neonatologists on neonates' outcome (weight changes, adequacy of parenteral nutrition, days of hospitalization, clinical outcome). SETTING The study took place at "Mitera" Maternity Hospital of Greece. METHOD Two groups of 30 preterm infants (28-36 weeks) with respiratory failure were recruited for the study. They were admitted in a Greek maternity hospital and they all received total parenteral nutrition support in neonates' intensive care unit. Standardized, computer based protocols were applied for the prescription of parenteral nutrition formulations in the first group, while on the other, regimens prescribed by neonatologists were used. MAIN OUTCOME MEASURES Macro- and micronutrients provided by the different total parenteral nutrition protocols were recorded. Body weight was measured, blood count and biochemical profile were performed at the beginning and at the end of parenteral nutrition support. The number of days of total parenteral nutrition support as well as the total number of days of hospitalization was recorded. RESULTS Standardized protocols provided more energy (P-value: 0.05), protein (P-value: 0.023) and micronutrients than the non-standardised. Neonates that receive standardized total parenteral nutrition gained weight (+44 +/- 114 g) and had better blood count and biochemical values during total parenteral nutrition support compared to the other group, that lost weight during total parenteral nutrition support (-53 +/- 156 g). These differences were also statistically significant (P value < 0.05). Regarding the total days of hospitalization, no differences were found between the two groups. CONCLUSION The use of standardized protocols in preterm neonates resulted in more adequate provision of nutrients, weight gain and better blood count profile compared with protocols prescribed by individual physicians.

Abstract
BACKGROUND On postdilution hemodiafiltration (post-HDF), convective removal of medium-high molecular weight solutes is, at the highest ultrafiltration rates, limited by high blood viscosity and protein concentration. Prefilter reinfusion (pre-HDF) may overcome this problem, but plasma dilution may affect the overall efficiency of the technique. In this study, an experimental system of online HDF with combined prefilter and postfilter infusion (mixed HDF) was evaluated and compared with the traditional predilution and postdilution modes. METHODS Removal of urea (U), creatinine (Cr), phosphate (Phos), and beta(2)-microglobulin (beta(2)m), ultrafiltration coefficients of the dialyzer (K(UF)), and rheologic conditions of the blood circuit were evaluated during the three infusion modes (a total of 36 runs lasting 180 min), performed with a polysulfone hemofilter 1.8 m(2), blood flow (Q(b)) 400 mL/min, dialysate flow (Q(d)) 700 mL/min, and infusion rate 120 mL/min (pre-HDF and post-HDF), or 60 + 60 mL/min (mixed HDF). RESULTS The mean effective U and Cr clearances and urea index of dialysis dose (eKt/V) were significantly higher on post-HDF than on pre-HDF (K(WB) (U) 210 vs. 193 mL/min, K(DQ) (Cr) 152 vs. 142 mL/min, eKt/V 1.41 vs. 1.30), while mixed HDF did not show significant differences versus post-HDF (K(WB) (U) 201 mL/min, K(DQ) (Cr) 149 mL/min). K(DQ) for Phos and beta(2)m were higher on post-HDF in only absolute values. Similar differences were found for instantaneous dialyzer clearances (K(I)) at 60, 120, and 180 minutes of the sessions, with a common trend to decrease with time. K(UF) and the apparent beta(2)m sieving coefficient showed their lowest values toward the end of post-HDF sessions. Increasing filtration fractions (FFs) were associated with increasing transmembrane pressure (TMP) and solute clearances up to FF values of 0.45. These were values achieved in only post-HDF, at which point the curve of the relationship between TMP and FF assumed its steepest exponential trend. CONCLUSIONS Mixed HDF, by better preserving the characteristics of water and solute transport of the membrane, ensured safer operating conditions than post-HDF, while achieving similar removal of small- and large-size solutes. Optimizing the ratio of prefilter/postfilter infusion and the total infusion according to the relationships found in our study between solute clearances, FF, and TMP, convective flux and transport may avoid excessive hemoconcentration and dangerous pressure gradients.
