Studies on the potential benefits of conveying biofeedback stimulus using a musical signal have appeared in recent years with the intent of harnessing the strong effects that music listening may have on subjects. While results are encouraging, the fundamental question has yet to be addressed, of how combined music and biofeedback compares to the already established use of either of these elements separately. This experiment, involving young adults (N. = 24), compared the effectiveness at modulating participants' states of physiological arousal of each of the following conditions: A) listening to pre-recorded music, B) sonification biofeedback of the heart rate, and C) an algorithmically modulated musical feedback signal conveying the subject's heart rate. Our hypothesis was that each of the conditions (A), (B) and (C) would differ from the other two in the extent to which it enables participants to increase and decrease their state of physiological arousal, with (C) being more effective than (B), and both more than (A). Several physiological measures and qualitative responses were recorded and analyzed. Results show that using musical biofeedback allowed participants to modulate their state of physiological arousal at least equally well as sonification biofeedback, and much better than just listening to music, as reflected in their heart rate measurements, controlling for respiration-rate. Our findings indicate that the known effects of music in modulating arousal can therefore be beneficially harnessed when designing a biofeedback protocol. © 2013 Elsevier B.V. Source

Background: Idiopathic non-cirrhotic portal hypertension (INCPH) is a rare life-threatening liver disease that lacks a specific diagnostic test being frequently misdiagnosed as cryptogenic cirrhosis. Preliminary data from our group identified a plasma metabolomic profile able to differentiate INCPH from patients with cirrhosis (CH) and healthy volunteers (HV). However, the untargeted methodology applied was unable to identify all the specific metabolites, hampering the possibility of building-up diagnostic models. This study applies a wide-coverage of previously identified metabolites through a high-throughput metabolomics technology, evaluating if there is a metabolomic profile that allows a non-invasive diagnosis of INCPH. Methods: We included 34 patients with INCPH, 34 with CH and 34 HV. We performed a targeted metabolomic analysis of serum samples using UPLC-MS. The best combination of a set of specific metabolites was obtained using stepwise logistic regression (LR) and recursive partitioning analysis (RPA). Results: After internal cross-validation, LR analysis identified a subset of 5-metabolites that clearly differentiate INCPH patients from CH and HV (average corrected optimism AUROC = 0.8871 [0.838–0.924]). Using high and low cut-off values the model has an excellent capacity to respectively diagnose or exclude INCPH. The RPA analysis strategy used the 3-metabolites signature differentiating INCPH from CH and the 2-metabolites signature differentiating INCPH from HV. A decision tree applying sequentially these metabolic profiles diagnosed 88% of INCPH patients. Conclusions: Different metabolomic profiles allow the diagnosis of INCPH with high specificity and sensibility and may represent excellent clinical tools for its diagnosis avoiding multiple and invasive tests. © 2015 John Wiley & Sons A/S.

Objective: The purpose of this study was to evaluate the effects of prenatal exposure to selective serotonin reuptake inhibitors (SSRIs) on obstetrical and neonatal outcomes. Method: A case-control study was conducted to compare perinatal outcomes among pregnant women with affective disorder (DSM-IV criteria) and who received SSRIs during pregnancy with those of women without an active psychiatric disorder during pregnancy who were non-exposed to antidepressants during pregnancy. Each case was matched to two controls for maternal age (± 2 years) and parity. Results: A total of 252 women were enrolled in the study, 84 exposed and 168 non-exposed. Demographic and clinical characteristics did not differ significantly between the groups. The rates of prelabor rupture of membranes, induction of labor and cesarean delivery were slightly higher but not statistically significant in the exposed group. The mean gestational age at birth was 38.8 (± 1.86) weeks for the exposed group and 39.4 (± 1.52) weeks for the non-exposed group (p =.005). Rates for preterm birth were higher in the exposed group (OR = 3.44, 95% CI = 1.30-9.11). After stratification for dose, it was found that exposure to a high-dose was associated with lower gestational age (p =.009) and higher rates of prematurity (OR = 5.07, 95% CI = 1.34-19.23). The differences remained significant after controlling for maternal status and the length of exposure. Conclusion: Women treated with SSRIs during pregnancy, mainly at high-dose, had an increased risk of preterm birth compared to healthy women of similar age and parity who were not exposed to SSRI during pregnancy. © 2011 Elsevier B.V.

Background Noninvasive identification of significant portal hypertension in patients with cirrhosis is needed in hepatology practice. Aim To investigate whether the combination of sCD163 as a hepatic inflammation marker and the fibrosis markers of the Enhanced Liver Fibrosis score (ELF) can predict portal hypertension in patients with cirrhosis. Methods We measured sCD163 and the ELF components (hyaluronic acid, tissue inhibitor of metalloproteinase-1 and procollagen-III aminopeptide) in two separate cohorts of cirrhosis patients that underwent hepatic vein catheterisation. To test the predictive accuracy we developed a CD163-fibrosis portal hypertension score in an estimation cohort (n = 80) and validated the score in an independent cohort (n = 80). A HVPG ≥10 mmHg was considered clinically significant. Results Both sCD163 and the ELF components increased in a stepwise manner with the patients' Child-Pugh score (P < 0.001, all), and also with increasing HVPG (P < 0.001). receiver operator characteristics (ROC) analyses showed that each one of the individual components predicted a HVPG >10 mmHg with AUROC′s of approximately 0.80. The combined score optimised by logistic regression analyses improved the AUROC to 0.91 in the estimation cohort and 0.90 in the validation cohort. Furthermore, a high value of the combined score was associated with a high short-term mortality. Conclusions The combination of the macrophage activation marker sCD163 and the fibrosis markers predicted significant portal hypertension in patients with cirrhosis. This score may prove useful for screening purposes and highlights the importance of both the inflammatory and the fibrotic components of cirrhotic portal hypertension. © 2016 John Wiley & Sons Ltd.

The Vulnerable Personality Style Questionnaire (VPSQ) is a nine-item self-report scale developed to asses personality traits which increase the risk of postpartum depression. The aim of the present study was to examine the psychometric properties of the Spanish version of the VPSQ in a sample of postpartum women. A cohort of 309 postpartum women was followed up for 32 weeks after delivery. All women were assessed with the Spanish version of the VPSQ, the Eysenck Personality Questionnaire-R Short Scale, the Frost Multidimensional Perfectionism Scale and the harm avoidance dimension of the Temperament and Character Inventory at 2-3 days postpartum. Depressive symptoms were evaluated at 8 and 32 weeks after delivery by the Edinburgh Postnatal Depression Scale, and a diagnostic interview was used to confirm the presence of major depression disorder. Factor analysis results revealed the unidimensionality of the Spanish version of the VPSQ. Cronbach's alpha coefficient for the VPSQ total score was 0.63. The test-retest reliability indicated a good temporal stability (ICC = 0.88; 95% confidence interval (CI) = 0.82-0.91). A moderate association between the VPSQ and other personality measures provided evidence for its construct validity. Logistic regression analyses showed that women with higher scores on the VPSQ had a higher risk of developing depressive symptoms (OR = 1.20; 95% CI = 1.11-1.29) and major depression (OR = 1.16; 95% CI = 1.07-1.26) throughout the 32 weeks after delivery. Overall, our results suggest adequate psychometric properties of the Spanish version of the VPSQ and its usefulness in identifying women with a personality style that increases the risk of developing postpartum depression. © 2010 Springer-Verlag.
