Abstract
BACKGROUND Suboptimal response to ursodeoxycholic acid occurs in 40% of primary biliary cholangitis (PBC) patients, affecting survival. Achieving a deep response (normalisation of alkaline phosphatase [ALP] and bilirubin ≤0.6 upper limit of normal) improves survival. Yet, the long-term effectiveness of second-line treatments remains uncertain. AIMS To evaluate the long-term effectiveness of obeticholic acid (OCA) ± fibrates. Focusing on biochemical response (ALP ≤1.67 times the upper limit of normal, with a decrease of at least 15% from baseline and normal bilirubin levels), normalisation of ALP, deep response and biochemical remission (deep response plus aminotransferase normalisation). METHODS We conducted a longitudinal, observational, multicentre study involving ursodeoxyccholic acid non-responsive PBC patients (Paris-II criteria) from Spain and Portugal who received OCA ± fibrates. RESULTS Of 255 patients, median follow-up was 35.1 months (IQR: 20.2-53). The biochemical response in the whole cohort was 47.2%, 61.4% and 68.6% at 12, 24 and 36 months. GLOBE-PBC and 5-year UK-PBC scores improved (p < 0.001). Triple therapy (ursodeoxycholic acid plus OCA plus fibrates) had significantly higher response rates than dual therapy (p = 0.001), including ALP normalisation, deep response and biochemical remission (p < 0.001). In multivariate analysis, triple therapy remained independently associated with biochemical response (p = 0.024), alkaline phosphatase normalisation, deep response and biochemical remission (p < 0.001). Adverse effects occurred in 41.2% of cases, leading to 18.8% discontinuing OCA. Out of 55 patients with cirrhosis, 12 developed decompensation. All with baseline portal hypertension. CONCLUSION Triple therapy was superior in achieving therapeutic goals in UDCA-nonresponsive PBC. Decompensation was linked to pre-existing portal hypertension.

Abstract
Feline leukemia virus (FeLV) infection is considered one of the most serious disease threats for the endangered Iberian lynx (Lynx pardinus) Over 14 years (2008-2021), we investigated FeLV infection using point-of-care antigen test and quantitative real-time TaqMan qPCR for provirus detection in blood and tissues in lynxes from Andalusia (Southern Spain). A total of 776 samples from 586 individuals were included in this study. The overall prevalence for FeLV antigen in blood/serum samples was 1.4% (5/360) (95% CI: 0.2-2.6), FeLV proviral DNA prevalence in blood samples was 6.2% (31/503) (95% CI: 4.1-8.6), and FeLV proviral DNA in tissues samples was 10.2% (34/333) (95% CI: 7-13.5). From a subset of 129 longitudinally sampled individuals, 9.3% (12/129) PCR-converted during the study period. Our results suggest that FeLV infection in the Andalusian population is enzootic, with circulation of the virus at low levels in almost all the sampling years. Moreover, since only one viremic individual succumbed to the infection, this study suggests that lynxes may therefore control the infection decreasing the possibility of developing a more aggressive outcome. Although our results indicate that the FeLV infection in the Iberian lynx from Andalusia tends to stay within the regressive stage, continuous FeLV surveillance is paramount to predict potential outbreaks and ensure the survival of this population.

Abstract
Background Due to the accessibility barriers of in-person programs for active aging, the development of programs that use innovative technologies is needed. Video games can be an engaging tool for disseminating active aging interventions. Objective The objective of this pilot study was to analyze the feasibility of a cognitive-behavioral intervention to promote active aging administered through a video game. Methods Fifty-five participants (63.6% women, mean age = 53.0 years) were randomly assigned to a cognitive-behavioral intervention to promote active aging administered through an interactive multimedia online video game with a complementary app (CBI-V; n = 29) or to a control group that received nonspecific online information (CG; n = 26). Results Only 3.6% of the participants dropped out of the study (6.9% in CBI-V and 0.0% in CG; without significant differences between groups). The mean number of modules completed was 7.6 (SD = 0.9) out of 8 in the CBI-V and 7.9 (SD = 0.5) in the control group (CG), without significant between-group differences. In the CBI-V, the mean total time dedicated to the game was 516.8 min (SD = 94.3), including 143.2 min (SD = 31.6) of cognitive training tasks, and the mean of completed tasks was 206.2 (SD = 33.7) out of 259. Participants were highly engaged (M = 39.9, SD = 8.6) and satisfied (M = 25.8, SD = 4.5) with the intervention. After the intervention, the CBI-V group significantly improved on SF-36 dimensions of General Health (p = .0386), Vitality (p = .0283), Social Functioning (p = .0130), and Physical Summary Index (p = .0370) compared to the CG, with medium effect sizes (d = 0.56-0.75). Conclusions The results demonstrate the feasibility of the video game intervention to promote active aging and encourage conducting a large-scale randomized controlled trial.

Abstract
This study aimed to determine the prevalence and associated factors of poor sleep quality in non-professional caregivers. With this purpose, cross-sectional data were collected from 201 dependent people's family caregivers using the Pittsburgh Sleep Quality Index (PSQI), the Caregiver Burden Inventory (CBI), the General Health Questionnaire (GHQ-12), and an ad hoc questionnaire to obtain sociodemographic data. A total of 153 family caregivers were categorized as poor sleepers (PSQI > 5), resulting in a prevalence of poor sleep quality of 76.1% (95% CI = 70.5-82.5). Poor sleepers were more likely to care for persons with mental disorders (χ2 = 7.31; p < 0.01) and scored significantly higher on perceived burden (z = -4.44; p < 0.001), psychological distress (z = -6.24; p < 0.001), and in all the PSQI subscales (p < 0.001), compared with good sleepers (PSQI ≤ 5). By contrast, no differences were found between poor and good sleepers in age, gender, years providing care, and daily hours of care. Multiple linear regression analysis showed that the factors of caregiver burden (β = 0.15; p < 0.05) and psychological distress (β = 0.53; p < 0.001) were significantly associated with sleep quality in dependent people's family caregivers. Cognitive-behavioral strategies to improve sleep quality in the primary health care of family caregivers are suggested.

Abstract
Objectives: The efficacy of new direct-acting antivirals (DAAs) in treating hepatitis C infection can depend on treatment adherence, which may be influenced by the patient’s current lack of awareness of the disease. This study set out to understand the treatment naïve chronic hepatitis C patients’ preferences for new DAAs (attributes) and to compile information about the diagnosis process. Material and method: Spanish quantitative market research study conducted between November 2018 and January 2019 to assess the posology preferences of treatment-naïve patients with chronic hepatitis C before starting treatment (seen by hepatologists and infectious diseases specialists). A telephone interview was carried out to collect demographic, diagnostic and treatment preference data, consisting of two dosing OPTIONS: 1) three tablets/day (single dose), at the same time, with food (8 weeks). 2) single tablet/day, at any time with/without food (12 weeks). A descriptive analysis of pooled results was performed. Results: 104 patients (mean age: 49 years) with hepatitis C diagnosed 7.3±9.7 years ago (average), mainly in primary care (PC) (42%). The most common reasons for not having started treatment were health problems/comorbidities (31%). Fifty-eight percent of patients were not informed about the available treatments. Seventy-two percent of patients preferred a simple tablet/day, at any time, with/without food (12 weeks), and considered compatibility with other treatments, side effects, ease of administration, treatment duration and the number of tablets to be very important. Discussion: Patient preferences are mainly driven by dosing flexibility and simplicity, including freedom to take the medication with/without food. The role of PC in the diagnosis should be taken into account. There are still patients who are untreated after diagnosis.

Abstract
Motivational processes and emotional self-regulation are relevant factors for predicting the practice of physical exercise and for certain health-related parameters. The aim of the present work, developed along two different phases, was, on the one hand, to determine the prevalence of physical inactivity and, on the other hand, to carry out a comparative analysis between physically active and inactive university students in relation to their motivational determinants, emotional self-regulation, physical condition, health-related quality of life and other health parameters. The results obtained showed a prevalence of physical inactivity of 12.78%. Physically inactive participants showed significantly lower scores in intrinsic motivation, emotion regulation, and in some dimensions of health-related quality of life, as well as significantly high levels of body fat mass. Lastly, logistic regression analysis identified low scores in Emotional Clarity (p= .009) and Identified Regulation (p = .011), and high scores in Amotivation (p = .006) as reliable predictors of a physically inactive lifestyle. These results are useful for the design and implementation of programs aimed at promoting health and physical activity, with special attention on physically inactive youth populations.

Abstract
We study heat rectification in a minimalistic model composed of two unequal atoms subjected to linear forces and in contact with effective Langevin baths induced by Doppler lasers. Analytic expressions of the heat currents in the steady state are spelled out. Asymmetric heat transport is found in this linear system if both the bath temperatures and the temperature-dependent bath-system couplings are exchanged. The model can be realized with two ions in either common or individual traps. This physical setting allows for a natural temperature dependence of the coupling to the baths. We also explore the parameter space of the model to optimize asymmetric heat current and find conditions for maximal rectification. High rectification corresponds to a good match of the power spectra of the ions for forward temperature bias and mismatch for reverse bias, which may be understood by the behavior of dissipative normal modes.

Abstract
Dyssynergic defecation is a usual cause of chronic constipation in elderly women, with a negative impact on health-related quality of life. The present randomized controlled trial aims to evaluate the effects of behavioral treatment through electromyographic biofeedback (EMG-BF) on quality of life and bowel symptoms in elderly women with dyssynergic defecation. Twenty chronically constipated elderly women, due to dyssynergic defecation, were enrolled in the study. Outcome measures included weekly stool frequency, anismus index, severity of patient-reported chronic constipation symptoms (abdominal, rectal, and stool symptoms), and overall measure of quality of life. After 1 month of baseline, participants were randomly assigned to either EMG-BF group (n = 10) or control group (n = 10). Three months after treatment, female patients were once again assessed following the same procedure in baseline. One-way multivariate analysis of variance MANOVA revealed no significant differences between the groups before treatment in any of the measured dependent variables (Wilks's λ = 0.74; F6,13 = 0.77; p = 0.61). Likewise, univariate analysis showed no differences between the groups, either in terms of age (F1,18 = 0.96; p = 0.34) or mean disease duration (F1,18 = 2.99; p = 0.11). Three months after treatment, MANOVA revealed statistically significant differences between the groups (Wilks's λ = 0.29; F6,13 = 5.19; p < 0.01). These differences were significant in all outcome measures. EMG-BF produces significant improvements in bowel symptoms and health-related quality of life of elderly women with dyssynergic defecation.

Abstract
We numerically demonstrate heat rectification for linear chains of ions in trap lattices with graded trapping frequencies, in contact with thermal baths implemented by optical molasses. To calculate the local temperatures and heat currents we find the stationary state by solving a system of algebraic equations. This approach is much faster than the usual method that integrates the dynamical equations of the system and averages over noise realizations.

Abstract
This study examined the relationship between caregiver burden and sleep quality in dependent people’s family caregivers. A cross-sectional study was carried out with 201 dependent people’s family caregivers and 92 non-caregivers controls. Participants completed the Pittsburgh Sleep Quality Index (PSQI), the Caregiver Burden Inventory (CBI), and an ad-hoc questionnaire to collect sociodemographic data. Based on CBI scores, subjects were categorized into three groups: family caregivers with high levels of perceived burden, family caregivers with low and medium levels of perceived burden and non-caregiver controls. There were significant differences among the groups in the PSQI total (F = 40.39; p < 0.001), subjective sleep quality (F = 25.55; p < 0.001), sleep latency (F = 16.99; p < 0.001), sleep disturbances (F = 14.90; p < 0.001), use of sleep medications (F = 6.94; p < 0.01) and daytime dysfunction (F = 20.12; p < 0.001). These differences were found only between the caregivers with high levels of perceived burden and the other two groups (p < 0.05). There were also significant differences between the groups in sleep duration (F = 18.34; p < 0.001) and habitual sleep efficiency (F = 24.24; p < 0.001). In these dependent measures, the differences were found in all the pairs examined (p < 0.05). These results suggest that caregiver burden is related to sleep quality, so that caregivers with greater perceived burden have a worse sleep quality.

Abstract
Although the Caregiver Burden Inventory (CBI) is the most widely used multidimensional burden instrument for assessing perceived burden of caregivers, there is no data on its psychometric properties in Spanish, nor on caregivers of dependent persons with various diseases. The objective of this study was to translate the CBI into Spanish and validate it in caregivers of dependent persons with various diseases. Trained evaluators administered the CBI and assessed emotional distress and probable mental disorder in 201 caregivers (87.1% women, mean age 56.2 years). The internal consistency of the CBI was 0.89 (0.74–0.83 among the subscales). There was a significant correlation of emotional distress with both the total burden and each subscale (p < 0.001 in all cases). A total score of 39 and scores of 16, 9, 8, 4, and 2 in burden per time dedicated to care, personal life burden, physical burden, social burden, and emotional burden were suitable cut-off points to discriminate caregivers with probable mental disorder (sensitivity = 63.0%–75.6%, specificity = 63.4%–74.4%). To achieve a greater goodness of fit, the model was re-specified, resulting in a shortened (15-item) instrument. The internal consistency reliability coefficients of the 15-item CBI were satisfactory (Cronbach α = 0.83; 0.77–0.86 among the subscales). Within the 15-item CBI, emotional distress was significantly correlated with the total burden, personal life burden, physical burden, social burden (p < 0.001 in all those cases), and emotional burden (p = 0.001). A total score of 25 and scores of 12, 5, 5, 3, and 1, respectively, in the subscales were identified as cut-off points to discriminate caregivers with probable mental disorder (sensitivity = 46.2%–70.6%, specificity = 43.9%–79.3%). Therefore, the 15-item CBI validly measured caregiver burden with better fit and more parsimoniously than the original CBI.

Abstract
AIM OF THE STUDY The aim of this study was to evaluate the efficacy of biofeedback therapy in the treatment of dyssynergic defecation in chronically constipated community-dwelling elderly women. MATERIALS AND METHODS After an initial assessment phase carried out during 1 month, 20 chronically constipated women with dyssynergic defecation were randomly assigned to either electromyographic biofeedback (EMG-BF) group (n=10) or control group (n=10). Outcome measures used to evaluate the efficacy of treatment were weekly stool frequency, sensation of incomplete evacuation, difficulty evacuation level, mean EMG-activity (μV) of the external anal sphincter during straining to defecate and Anismus index. RESULTS The results obtained in this randomized controlled trial showed significant differences between the groups in all the dependent variables after 1 month of treatment. Moreover, there was no difference between the groups neither in age nor in the duration of chronic constipation symptoms. At the follow-up, 3 months later, clinical gains were maintained. CONCLUSIONS This study demonstrates that the EMG-BF is an effective behavioral therapy for the treatment of dyssynergic defecation in community-dwelling elderly women.

Abstract
BACKGROUND Hepatitis B virus (HBV) reactivation in patients with resolved HBV infection (HBsAg negative, antiHBc positive) is uncommon, but potentially fatal. The role of HBV prophylaxis in this setting is uncertain. The aim of this study was to compare the efficacy of tenofovir disoproxil fumarate (TDF) prophylaxis versus close monitoring in antiHBc-positive, HBsAg-negative patients under treatment with rituximab (RTX)-based regimens for hematologic malignancy. METHODS PREBLIN is a phase IV, randomized, prospective, open-label, multicenter, parallel-group trial conducted in 17 hospitals throughout Spain. Anti-HBc-positive, HBsAg-negative patients with undetectable HBV DNA were randomized to receive TDF 300 mg once daily (Group I) or observation (Group II). The primary endpoint was the percentage of patients showing HBV reactivation during 18 months following initiation of RTX treatment. Patients with detectable HBV DNA (Group III) received the same dose of TDF and were analyzed together with Group I to investigate TDF safety. RESULTS Sixty-one patients were enrolled in the study, 33 in the TDF treatment group and 28 in the observation group. By ITT analysis, HBV reactivation was 0% (0/33) in the study group and 10.7% (3/28) in the observation group (p = 0.091). None of the patients in either group showed significant differences in liver function parameters between baseline and the last follow-up sample. TDF was generally well tolerated and there were no severe treatment-related adverse events. CONCLUSION In patients with hematological malignancy and resolved hepatitis B infection receiving RTX-based regimens, HBV reactivation did not occur in patients given TDF prophylaxis.

Abstract
The relevance of several clinical and psychophysiological variables in the dyssynergic defecation in elderly subjects was investigated in this study. To accomplish this, 30 elderly subjects (10 without anorectal disorders, 10 with chronic constipation and 10 with dyssynergic defecation) were repeatedly assessed once per week for 4 weeks, with the following measures being collected at each session: EMG-activity (µV) of the external anal sphincter (at rest, during squeezing, and during straining to defecate), stool frequency, difficulty defecation level, pain grade during defecation, and satisfaction level after evacuation. A 3 (group) × 4 (sessions) mixed-measures MANOVA revealed a significant main effect for group (Wilks's lambda = 0.006; F = 28.45; p < 0.01), but not for sessions (Wilks's lambda = 0.874; F = 0.94; p > 0.05) or for the group x sessions interaction (Wilks's lambda = 0.811; F = 1.45; p > 0.05). One-way ANOVA and Scheffé's posthoc tests were used to isolate the differences between the groups with respect to the seven different measures. These analysis showed significant differences between the groups on all four clinical variables but only for one psychophysiological variable, EMG-activity during straining to defecate. Significant differences were evidenced between all pairs examined for the difficulty defecation level and pain grade. The complete results of these analysis are presented and the conclusions drawn from them are discussed.

Abstract
BACKGROUND Celsior solution (CS) is a high-sodium, low-potassium, low-viscosity extracellular solution that has been used for liver graft preservation in recent years, although experience with it is still limited. We performed an open-label randomized active-controlled trial comparing CS with the University of Wisconsin solution (UW) for liver transplantation (LT), with a follow-up period of 5 years. METHODS Adult transplant recipients (n=102) were prospectively randomized to receive either CS (n=51) or UW (n=51). The two groups were comparable with respect to donor and recipient characteristics. The primary outcome measure was the incidence of postreperfusion syndrome (PRS). Secondary outcome measures included primary nonfunction (PNF) or primary dysfunction (PDF), liver retransplantation, and graft and patient survival. Other secondary outcome measures were days in the intensive care unit (ICU) and the rates of acute rejection, chronic rejection, infectious complications, postoperative reoperations, and vascular and biliary complications. RESULTS In all, 14 posttransplant variables revealed no significant differences between the groups. There were no cases of PNF or PDF. The incidence of PRS was 5.9% in the CS group and 21.6% in the UW group (P=0.041). After reperfusion, CS revealed greater control of serum potassium (P=0.015), magnesium levels (P=0.005), and plasma glucose (P=0.042) than UW. Respective patient survivals at 3, 12, and 60 months were 95.7, 87.2, and 82.0% for the CS group and 95.7, 83.3, and 66.6% for the UW group (P=0.123). CONCLUSIONS While retaining the same degree of safety and effectiveness as UW for LT, CS may yield postliver graft reperfusion benefits, as shown in this study by a significant reduction in the incidence of PRS and greater metabolic control.

Abstract
The Iberian lynx is the most endangered felid species. During winter/spring 2006/7, a feline leukemia virus (FeLV) outbreak of unexpected virulence killed about 2/3 of the infected Iberian lynxes. All FeLV-positive animals were co-infected with feline hemoplasmas. To further characterize the Iberian lynx FeLV strain and evaluate its potential virulence, the FeLV envelope gene variable region A (VRA) mutant spectrum was analyzed using the Roche 454 sequencing technology, and an in vivo transmission study of lynx blood to specified-pathogen-free cats was performed. VRA mutations indicated weak apolipoprotein B mRNA editing enzyme and catalytic polypeptide-like cytidine deaminase (APOBEC) restriction of FeLV replication, and variants characteristic of aggressive FeLV strains, such as FeLV-C or FeLV-A/61C, were not detected. Cats exposed to FeLV/Candidatus Mycoplasma haemominutum-positive lynx blood did not show a particularly severe outcome of infection. The results underscore the special susceptibility of Iberian lynxes to infectious diseases.

Abstract
The Iberian lynx is the most endangered felid in the world. Enteropathogens may threaten its survival, and therefore we analysed faecal samples from 66 different individuals (37 males and 29 females), the largest population representation studied to date. The samples were obtained from November 2005 to October 2008 in the two areas where the Iberian lynx survives: Sierra Morena and Doñana (Andalusia, southern Spain). A total of 56.1% samples were parasitized with at least 6 species of helminths, including two cestodes (Hymenolepis spp. and Taenia spp.) and four Nematodes (Ancylostoma spp., Toxocara spp., Toxascaris leonina, and Capillaria sp.). In this work, the presence of Hymenolepis is reported for the first time in Lynx pardinus. The relevance of our findings is discussed focussed on the conservation of this endangered felid.

Abstract
The purpose of this study was to assess the relation between depression, gender and systemic manifestations in chronic inflammatory bowel diseases. With this aim, 106 patients (57 with Crohn disease and 49 with ulcerative colitis) were divided into 4 groups: men with extraintestinal manifestations (n= 10), men without extraintestinal manifestations (n= 36), women with extraintestinal manifestations (n= 15), and women without extraintestinal manifestations (n= 45). Depression was assessed with the Beck Depression Inventory. The results reveal significant effects both in the systemic manifestations factor (F= 28,33; p<0.01), and in the interaction between systemic manifestations and gender (F= 5,2; p<0.05); the gender factor, in contrast, was nonsignificant (F= 0,28; p>0.05). The finding of higher levels of depression in patients with systemic manifestations, particularly in men, underlines the need for psychological intervention aimed at detection and effective treatment.

Abstract
BACKGROUND The aim of our study was to determine concentrations of amino-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with cirrhosis, thereby describing the hemodynamic and cardiac profiles to verify the existence of cirrhotic cardiomyopathy. METHODS Clinical data, NT-proBNP levels, echocardiography, and right heart hemodynamic measurements were performed on all patients undergoing liver transplantation for cirrhosis. RESULTS Our patients showed a hyperdynamic circulation with elevated left-sided pressures despite high cardiac outputs. This observation suggested abnormalities in left ventricular diastolic compliance. We verified these results, because our cohort showed a significant left ventricular mass index and, consequently, diastolic dysfunction. Mean NT-proBNP levels were high. The great expansion of central volume may explain these results and the later development of left ventricular hypertrophy. CONCLUSION We concluded that elevated concentrations of NT-proBNP indicated the presence of hyperdynamic syndrome and cardiac dysfunction.

Abstract
BACKGROUND The Iberian lynx (Lynx pardinus) is considered the most endangered felid species in the world. In order to save this species, the Spanish authorities implemented a captive breeding program recruiting lynxes from the wild. In this context, a retrospective survey on prevalence of selected feline pathogens in free-ranging lynxes was initiated. METHODOLOGY/ PRINCIPAL FINDINGS We systematically analyzed the prevalence and importance of seven viral, one protozoan (Cytauxzoon felis), and several bacterial (e.g., hemotropic mycoplasma) infections in 77 of approximately 200 remaining free-ranging Iberian lynxes of the Doñana and Sierra Morena areas, in Southern Spain, between 2003 and 2007. With the exception of feline immunodeficiency virus (FIV), evidence of infection by all tested feline pathogens was found in Iberian lynxes. Fourteen lynxes were feline leukemia virus (FeLV) provirus-positive; eleven of these were antigenemic (FeLV p27 positive). All 14 animals tested negative for other viral infections. During a six-month period in 2007, six of the provirus-positive antigenemic lynxes died. Infection with FeLV but not with other infectious agents was associated with mortality (p<0.001). Sequencing of the FeLV surface glycoprotein gene revealed a common origin for ten of the eleven samples. The ten sequences were closely related to FeLV-A/61E, originally isolated from cats in the USA. Endogenous FeLV sequences were not detected. CONCLUSIONS/SIGNIFICANCE It was concluded that the FeLV infection most likely originated from domestic cats invading the lynx's habitats. Data available regarding the time frame, co-infections, and outcome of FeLV-infections suggest that, in contrast to the domestic cat, the FeLV strain affecting the lynxes in 2007 is highly virulent to this species. Our data argue strongly for vaccination of lynxes and domestic cats in and around lynx's habitats in order to prevent further spread of the virus as well as reduction the domestic cat population if the lynx population is to be maintained.

Abstract
The aim of this study was to evaluate the temporal stability and the situational specificity of the intra-anal EMG-activity, as well as the individual specificity of this response in dyssynergic defecation patients. With this purpose, 26 individuals (13 with dyssynergic defecation and 13 without anorectal pathology) participated in two sessions of psychophysiological assessment, with an inter-session period of 1 week. At each session, the EMG-activity of external anal sphincter was recorded under four different conditions (baseline, voluntary contraction, reflex contraction and simulated defecation). The findings provide empirical evidence about temporal stability of the intra-anal EMG-activity, situational specificity of this response and the existence of a specific profile of intra-anal EMG-activity characteristic of patients with dyssynergic defecation.

Abstract
Given that studies about the differential efficacy of existing treatments in fibromyalgia syndrome are scarce, the aim of this study was to compare the differential efficacy of a cognitive-behavioral and a pharmacological therapy on fibromyalgia. Using a randomized controlled clinical trial, 28 fibromyalgic patients were assigned to one of following experimental conditions: (a) pharmacological treatment (i.e., cyclobenzaprine), (b) cognitive-behavioral intervention (i.e., stress inoculation training), (c) combined pharmacological and cognitive-behavioral treatment and (d) no treatment. The results show the superiority of cognitive-behavioral intervention to reduce the severity of fibromyalgia both at the end of the treatment and at follow-up. We conclude that cognitive-behavioral interventions must be considered a primary treatment of fibromyalgia syndrome.

Abstract
Recent studies have revealed elevated expression of transforming growth factor beta1 (TGF-beta1) in gastric mucosa of patients with gastric cancer (GC) and those undergoing ulcer repair. As production of TGF-beta1 is genetically regulated, we aimed to assess whether functional polymorphisms of the TGFB1 gene are involved in susceptibility to and clinical characteristics of Helicobacter pylori-related diseases. DNA from 142 unrelated Spanish patients with GC, 200 with peptic ulcer and 342 healthy controls was typed for the MspA1I T+869C, and the Sau96I G+915C polymorphisms of the TGFB1 gene using polymerase chain reaction and RFLP analysis. H. pylori infection and CagA/VacA antibody status were determined by Western blot in patients and controls. H. pylori infection (odds ratio (OR): 11.44; 95% confidence interval (CI): 4.45-29.42; P<0.001) and non-steroidal anti-inflammatory drugs (OR: 5.07; 95% CI: 2.53-10.16; P<0.001) were identified as independent risks factors for duodenal ulcer (DU), whereas the TGFB1+869(*)C/C genotype was associated with reduced risk of developing the disease (OR: 0.32; 95% CI=0.15-0.68; P=0.003). Our results show that the TGFB1 T+869C gene polymorphism is involved in the susceptibility to DU and provide further evidence that host genetic factors play a key role in the pathogenesis of H. pylori-related diseases.

Abstract
Abstract. The short(s)-EMBU (Swedish acronym for Egna Minnen Beträffande Uppfostran [My memories of upbringing]) consists of 23 items, is based on the early 81-item EMBU, and was developed out of the necessity of having a brief measure of perceived parental rearing practices when the clinical and/or research context does not adequately permit application of time-consuming test batteries. The s-EMBU comprises three subscales: Rejection, Emotional Warmth, and (Over)Protection. The factorial and/or construct validity and reliability of the s-EMBU were examined in samples comprising a total of 1950 students from Australia, Spain, and Venezuela. The data were presented for the three national groups separately. Findings confirmed the cross-national validity of the factorial structure underlying the s-EMBU. Rejection by fathers and mothers was consistently associated with high trait-neuroticism and low self-esteem in recipients of both sexes in each nation, as was high parental emotional warmth with high femininity (humility). The findings on factorial validity are in keeping with previous ones obtained in East Germany, Greece, Guatemala, Hungary, Italy, and Sweden. The s-EMBU is again recommended for use in several different countries as a reliable, functional equivalent to the original 81-item EMBU.

Abstract
The Fear Survey Schedule-III (FSS-III) was administered to a total of 5491 students in Australia, East Germany, Great Britain, Greece, Guatemala, Hungary, Italy, Japan, Spain, Sweden, and Venezuela, and submitted to the multiple group method of confirmatory analysis (MGM) in order to determine the cross-national dimensional constancy of the five-factor model of self-assessed fears originally established in Dutch, British, and Canadian samples. The model comprises fears of bodily injury-illness-death, agoraphobic fears, social fears, fears of sexual and aggressive scenes, and harmless animals fears. Close correspondence between the factors was demonstrated across national samples. In each country, the corresponding scales were internally consistent, were intercorrelated at magnitudes comparable to those yielded in the original samples, and yielded (in 93% of the total number of 55 comparisons) sex differences in line with the usual finding (higher scores for females). In each country, the relatively largest sex differences were obtained on harmless animals fears. The organization of self-assessed fears is sufficiently similar across nations to warrant the use of the same weight matrix (scoring key) for the FSS-III in the different countries and to make cross-national comparisons feasible. This opens the way to further studies that attempt to predict (on an a priori basis) cross-national variations in fear levels with dimensions of national cultures.

Abstract
Recombinant factor VIIa (rfVIIa) has been widely used for the treatment and prevention of bleeding episodes in haemophiliacs with high-titre inhibitors. High single doses are the treatment of choice for joint and muscle bleeds in those patients. There are only a few reports on the value of rfVIIa in cirrhotic patients with haemostatic impairment but this drug can consistently correct the prothrombin time in these individuals. We report a case of a good response to a single high dose of rfVIIa in a patient with advanced liver disease who suffered from severe refractory postoperative haematuria.

Abstract
Ivermectin was used to treat sarcoptic mange in Spanish ibex (Capra pyrenaica hispanica). Its therapeutic effectiveness was analyzed when it was administered through subcutaneous injection, to sick animals in the consolidation stage of mange (third phase) and, with double injections to chronically affected animals (fourth phase) at a dosage of 0.2 or 0.4 mg/kg body weight (bw). Three wk after treatment, the animals in the third phase of mange treated with a high dose (0.4 mg/kg bw) of ivermectin were completely cured. The same result was achieved after 4 wk of treatment in those animals in phase 3 of mange when 0.2 mg/kg body weight was used. Double injection with ivermectin, even at high doses, did not guarantee the complete cure of all cases of sarcoptic mange in the chronic stage (phase 4); only three of six animals were free of Sarcoptes scabiei. The second experiment consisted on the application of a sanitation program in order to obtain a population of Spanish ibex free from S. scabiei, starting with free-ranging animals, some of them healthy and others sick. After capture the animals were classified as chronically ill, in which case they were excluded from the program, mite carriers and healthy specimens. All the animals were treated first topically with foxim (500 mg/l) and subcutaneously with ivermectin (0.4 mg/kg bw). The infected animals were housed in the treatment pen, and received two doses of ivermectin (0.2 mg/kg bw) at an interval of 15 days, then spent 15 days in the quarantine pen, where they received a further dose before they were included in the pool of healthy animals, and immediately were placed in the quarantine phase. The sanitation we implemented was fully effective in curing the affliction of Spanish ibex affected by S. scabiei.

Abstract
The combination of interferon (IFN) and ribavirin is the current gold standard for treatment of chronic hepatitis C virus (HCV) infection with sustained remission rates of 35--40% being achieved in haemophilic patients. A similar beneficial effect of this combined therapy has been suggested even for patients with compensated liver cirrhosis and some authors have reported a possible role for IFN and ribavirin in the prevention or delay in the development of hepatocellular carcinoma (HCC), a well known complication of HCV infection in haemophiliacs. The absence, due to design difficulties, of definite randomized controlled clinical trials remains a handicap for the routine use of specific therapy of HCV infected patients with the aim of preventing HCC. A discussion of these important issues has been performed in this paper.

Abstract
BACKGROUND To analyze cost-effectiveness of two different strategies to treat H. pylori infection in peptic ulcer in the primary care setting. PATIENTS AND METHODS Consecutive patients with endoscopic diagnosis of peptic ulcer were randomized to one of two strategies: a) treatment during 7 days with omeprazole, tetracycline, metronidazole and bismuth subcitrate ("quadruple" therapy) and if failure second-line treatment with omeprazole, amoxycillin and clarithromycin during 7 days (OCA7), and b) initial treatment with OCA7 and if failure treatment with "quadruple therapy". End point was eradication 8 weeks after last treatment dose. Direct and indirect costs were estimated (euros, 1997) and a cost-effectiveness analysis using a decision-tree model was undertaken after real clinical data. 95% confidence intervals are given. RESULTS After screening 255 patients, 97 were finally included. 48 patients were given strategy a and 49 strategy b. Eradication was obtained (intention-to-treat) in 72.9% (CI 95%: 58.2-84.7) in group a versus 91.8% (CI 95%: 80.4-97.7) (p < 0.05) in group b. Mean cost per case treated was lower in group a (237 versus 268 euros) but cost per case eradicated was lower in group b (320 versus 296 euros). The cost was primarily determined by efficacy. CONCLUSIONS Treatment with OCA7 followed by rescue with "quadruple" therapy if failure is more efficient in our area that the inverse strategy. Efficiency is mostly determined by efficacy.

Abstract
BACKGROUND Data regarding the effectiveness of second-line treatment of Helicobacter pylori infection are limited, especially if microbiological studies are considered. METHODS AND PATIENTS We conducted a prospective, uncontrolled study of a consecutive series of 21 peptic ulcer patients with failure of 1-week lansoprazole, amoxicillin, and clarithromycin. H. pylori status was evaluated by urease test, histology, culture, and urea breath test. Susceptibility to amoxicillin, clarithromycin, and metronidazole was studied by E-test. Cure of infection was defined as negative results from endoscopy-based tests 1 month after treatment and negative results from a urea breath test at 2 months. Treatment consisted of a 1-week combination of lansoprazole (30 mg bid), tetracycline (500 mg qid), metronidazole (500 mg tid), and bismuth subcitrate (120 mg qid). RESULTS H. pylori was resistant to metronidazole in three cases, to clarithromycin in three cases, and to both clarithromycin and metroinidazole in an additional three patients. No resistance to amoxicillin was found. Eradication was obtained in 20 cases (95.2% confidence interval [CI], 76.2-99.9). The only patient in whom infection was not eradicated harbored a metronidazole-resistant (minimum inhibitory concentration > 32 micrograms/ml) strain. No significant side effects were reported. CONCLUSION Quadruple therapy obtains a high eradication rate even in patients with clarithromycin- and metronidazole-resistant strains. Further randomized and controlled studies are warranted and are urgently needed.

Abstract
The Spanish ibex (Capra pyrenaica hispanica) population of the "Sierras de Cazorla, Segura y Las Villas" Nature Park (Spain) was isolated as the result of a severe epidemic of sarcoptic mange. In this context, the dynamic characteristics of the disease were analyzed in a wild group consisting of 35 animals from the beginning of the epizootic (when the mating period started) to the extinction of the population due to mange. Monthly tracking permitted the sequential characterization of the pathology in each animal. The duration of the disease was 2 to 3 mo, evolving to severe disease and terminating in death. Incidence and prevalence rates in terms of morbidity and severity, and mortality and lethality were calculated. At the end of the mating season, 81% of the population were affected. There were no statistically significant differences in severity of the disease across sex or age categories of the animals. Most of the carcasses were found in caves used as refuge and/or near rivers or streams. Additionally, 46 of the 63 (73%) ibex captured in different areas of the nature park were naturally infected with the Sarcoptes scabiei. Infected ibex were examined for number of mites during the initial stage of the disease (n = 3), in the development stage (n = 12), in the consolidation stage (n = 17), and in the chronic stage (n = 14). The prevalence of mites in different anatomical regions was determined in each of these phases of the infection. A histological study of the skin lesions was conducted in 22 animals. Both the clinical and the pathological (macroscopic and microscopic) aspects of the sarcoptic mange in Spanish ibex corresponded to the classic description of sarcoptic mange in other wild and domestic small ruminants.

Abstract
BACKGROUND There are many reports that evaluate the efficacy of the combination of omeprazole, amoxicillin and clarithromycin in the eradication of Helicobacter pylori, but data about effectivity in clinical practice are sparse. The goal of our study is to evaluate the effectivity in the clinical setting of this combination with diverse durations and doses. METHODS This is a retrospective analysis of 187 patients (128 male and 59 female), with an endoscopic diagnosis of duodenal ulcer (156), gastric ulcer (25) and both (6) with Helicobacter pylori infection as defined by both: a positive ureasa test and histology. After diagnosis the patient were treated with one of three combinations: a) omeprazole: 20 mg/12 h + amoxicillin: 1 g/12 h + clarithromycin: 500 mg/12 h, during 6 days (n = 60); b) omeprazole: 20 mg/12 h + amoxicillin: 1 g/12 h + clarithromycin: 500 mg/12 h, during 7 days (n = 74), and c) omeprazole: 20 mg/12 h + amoxicillin: 1 g/8 h + clarithromycin: 500 mg/8 h, during 7 days (n = 53). After the 6 or 7 day treatment period the patients did not receive any further treatment until a follow-up control unit. Eradication was evaluated with one of two tests: endoscopy (with ureasa test and at least 4 histologic samples) (n = 90) or urea breath test according to european protocol (n = 97). RESULTS No patient dropped out because of side effects and compliance was above 80% in all cases. The global eradication rate was 87.2% (CI 95%: 82.4-92%). According to treatment the rate were respectively 80% (CI 95%: 67.7-89.2%) with scheme A; 89.2% (CI 95%: 79.8-95.2%) with scheme B, and 92.5% (CI 95%: 81.8-97.9%) with scheme C, with no statistically significant differences among groups. Difference between schemes and C, however, was almost reached (p = 0.053). CONCLUSIONS The combination of omeprazole, amoxicillin and clarithromycin at standard doses (scheme B) is effective in clinical practice. Higher dose of amoxicillin and clarithromycin does not improve the results, and shorter duration of therapy associated with lower, although not significant rate of eradication.

Abstract
AIM To compare the efficacy of omeprazole (40 mgs/12 h i.v.) and cimetidine (1,200 mgs/i.v./day) in the management of upper gastrointestinal bleeding. EXPERIMENTAL DESIGN Randomized, prospective open clinical trial. The end points are: mortality, surgical requirements, transfusion requirements, and length of hospitalization in Bleeding Unit and Hospital. PATIENTS We study patients with upper gastrointestinal bleeding from peptic sources (duodenal ulcer, gastriculcer, acute gastric erosions and peptic esophagitis). 462 patients are evaluated and 282 finally included. RESULTS 151 patients were given cimetidine and 131 omeprazole. No significant differences in any of the end points were found. CONCLUSIONS The use of omeprazole does not improve cimetidine efficacy in the entire group of patients with upper gastrointestinal bleeding.

Abstract
We report a series of 15 patients with a postoperative biliary fistula treated by endoscopic sphincterotomy. The exact location of the bile leak was revealed by ERCP in 13 cases (87%): cystic duct remnant in 6 (39%), intrahepatic biliary tree in 4 (26%), and main bile duct in 3 (20%). In all cases a distal obstacle (ie: retained stones, hydatid material) to bile flow was also found in ERCP. Treatment consisted of endoscopic sphincterotomy and subsequent removal of the distal obstacle, and could be completed in 13 (87%) cases. In our experience the treatment of postoperative biliary fistula with a distal obstruction bile flow by endoscopic sphincterotomy is a safe and effective procedure, and should be recommended as the first option in those patients.

Abstract
The presence of glucagon receptors on human adipocytes has not yet been described. In this work we present an exceptional case of glucagon binding to human adipocytes taken from a malignant tumor of adipose tissue of a patient with a liposarcoma. Binding analysis revealed that the total number of glucagon receptors on liposarcoma-cells was 99,000 and the apparent receptor affinity (ED:50) was 5 x 10(-9) M. Despite the presence of these specific receptors, glucagon was unable to induce a lipolytic response, or to activate the adenylate-cyclase system in these liposarcoma-cells. Whether the induction of glucagon receptors is a specific process of the tumor biology remains to be elucidated.

Abstract
In this paper, the preliminary results regarding the alterations of the biological action mechanism of insulin in several types of pathological accumulations of fat, i.e. lipomas, Madelung's Lipomatosis and liposarcoma, are presented. The results indicate significant alterations both at the insulin receptor and post-receptor levels, with reduced biological activity of this hormone, which could have and inductive role in the pathogenesis of such entities.

Abstract
It has been proposed that in liver cirrhosis portal hypertension causes splanchnic vasodilation and this induces blood volume expansion to maintain blood pressure. The current study was designed to explore the homeostatic response to sodium restriction, a maneuver aiming to contract blood volume, in compensated cirrhosis. Mean blood pressure, sympathetic nervous activity, and proximal sodium reabsorption were evaluated in 16 healthy control and 21 nonazotemic cirrhotic patients (11 without ascites and 10 with ascites) under two experimental conditions: after 4 days on a free sodium diet (basal condition) and after 4 days on a restricted sodium diet (40 mmol/day). No differences were observed in basal conditions in the above parameters between control and cirrhotic patients without ascites. However, cirrhotic patients with ascites showed lower basal values of mean blood pressure and higher basal levels of both plasma norepinephrine and fractional proximal sodium reabsorption than controls. Neither control nor cirrhotic patients with ascites showed significant changes in the measured parameters after sodium restriction. In contrast, in nonascitic patients, this maneuver induced an elevation in plasma norepinephrine concentration (164.4 +/- 24.6 vs. 270.1 +/- 24.9 pg/mL; mean +/- SEM; P less than 0.005) and in fractional proximal sodium reabsorption (86.4 +/- 2.1 vs. 91.8% +/- 0.5%; P less than 0.01). In addition, the nonascitic cirrhotic patients became hypotensive compared with controls (80.9 +/- 1.6 vs. 88.5 +/- 4.8 mm Hg; P less than 0.05) when subjected to the low-sodium diet. In patients without ascites, under conditions of sodium restriction, the decrease in mean arterial pressure correlated inversely with the increase in plasma norepinephrine concentration (r = -0.713; P less than 0.05), whereas the levels of plasma norepinephrine correlated directly with fractional proximal sodium reabsorption (r = 0.893; P less than 0.01). These findings suggest that ineffective circulatory volume is detected in nonascitic cirrhotic patients only under conditions of sodium restriction, but it is always present in cirrhotic patients with ascites, irrespectively of the amount of sodium in the diet. These results are compatible with the existence of fixed arterial vasodilation in cirrhosis.

Abstract
The usefulness and clinical applicability of quantitative plasma polymorphonuclear elastase determinations in the diagnosis of the severity of acute pancreatitis was analysed in a multicentre study and was compared with the usual prognostic systems of Ranson and Osborne et al. The study comprised 182 patients, 154 with a mild episode of acute pancreatitis and 28 with a severe episode, defined by the development of major complications or a fatal outcome. In the severe cases neutrophilic elastase reached significantly higher values than in mild cases (P less than 0.001) by the time the patient was admitted (2-12 h after the onset of the disease), reflecting considerable leucocyte activation. The sensitivity and specificity of this test are therefore greater than 90 per cent, with a positive severity predictive value of almost 80 per cent at the time of admission and 97 per cent after 24 h, and a negative predictive value of approximately 98 per cent. In addition to requiring 48 h for evaluation, the usual prognostic systems show a sensitivity of 77-85 per cent, a specificity of 70-77 per cent, a positive predictive value of 40-48 per cent, and a negative predictive value of 92-95 per cent, clearly lower than those obtained with leucocyte elastase. Polymorphonuclear elastase is therefore a very early and reliable marker in the diagnosis of the severity of acute pancreatitis, in addition to being easily adaptable to the routine of any hospital laboratory.
