El sesgo jumping to conclusions en trastornos afectivos
Objetivo: El sesgo de salto a conclusiones o Jumping To Conclusions (JTC) se describe como la tendencia a tomar decisiones apresuradas basadas en información insuficiente. Ha sido ampliamente estudiado en el ámbito de los trastornos psicóticos y otros trastornos mentales, detectándose prevalencias entre el 7% y el 50%. Sin embargo, no hay evidencia clara en los trastornos afectivos, desconociéndose su posible contribución al mantenimiento de conductas problemas en estas personas. Por tanto, este trabajo pretende explorar la prevalencia de JTC en los trastornos afectivos, según diagnósticos y las diferentes condiciones de la tarea de bolas.
Método: La muestra estaba formada por 101 participantes con diagnóstico de trastorno afectivo. El JTC se evaluó con la tarea de bolas, usando las proporciones más utilizadas en la tarea: 85:15 (no ambigüedad) y 60:40 (ambigüedad). Se considera presencia de JTC cuando el participante decide en el primer ensayo (criterio estricto) o en la segunda bola o antes (criterio laxo).
Resultados: Según el criterio estricto, el JTC estaba presente en un 27,7% de los participantes en el ratio de 85:15 y en un 23,8% en el ratio de 60:40. Bajo criterio laxo, la prevalencia de JTC en el ratio de 85:15 es 44,6% y el ratio de 60:40, es de 30,7%. También se extrajeron porcentajes en función del diagnóstico.
Conclusiones: El JTC está presente en los trastornos afectivos en un porcentaje similar a los descritos en la literatura, apoyando la no exclusividad del sesgo para los trastornos psicóticos. En el futuro, sería necesario explorar el papel del JTC en los procesos de toma de decisiones en personas con trastornos afectivos.2022-2
Polygenic Markers in Patients Diagnosed of Autosomal Dominant Hypercholesterolemia in Catalonia: Distribution of Weighted LDL-c-Raising SNP Scores and Refinement of Variant Selection
Hipercolesterolèmia familiar; Aterosclerosi; Puntuació de risc genèticFamilial hypercholesterolemia; Atherosclerosis; Genetic risk scoresHipercolesterolemia familiar; Aterosclerosis; Puntuaciones de riesgo genéticoFamilial hypercholesterolemia (FH) is associated with mutations in the low-density lipoprotein (LDL) receptor (LDLR), apolipoprotein B (APOB), and proprotein convertase subtilisin/kexin 9 (PCSK9) genes. A pathological variant has not been identified in 30–70% of clinically diagnosed FH patients, and a burden of LDL cholesterol (LDL-c)-raising alleles has been hypothesized as a potential cause of hypercholesterolemia in these patients. Our aim was to study the distribution of weighted LDL-c-raising single-nucleotide polymorphism (SNP) scores (weighted gene scores or wGS) in a population recruited in a clinical setting in Catalonia. The study included 670 consecutive patients with a clinical diagnosis of FH and a prior genetic study involving 250 mutation-positive (FH/M+) and 420 mutation-negative (FH/M−) patients. Three wGSs based on LDL-c-raising variants were calculated to evaluate their distribution among FH patients and compared with 503 European samples from the 1000 Genomes Project. The FH/M− patients had significantly higher wGSs than the FH/M+ and control populations, with sensitivities ranging from 42% to 47%. A wGS based only on the SNPs significantly associated with FH (wGS8) showed a higher area under the receiver operating characteristic curve, and higher diagnostic specificity and sensitivity, with 46.4% of the subjects in the top quartile. wGS8 would allow for the assignment of a genetic cause to 66.4% of the patients if those with polygenic FH are added to the 37.3% of patients with monogenic FH. Our data indicate that a score based on 8 SNPs and the75th percentile cutoff point may identify patients with polygenic FH in Catalonia, although with limited diagnostic sensitivity and specificityThis research was funded by the Instituto de Salud Carlos III (ISCIII), and Fondo Europeo de DesarrolloRegional (FEDER) “Una manera de hacer Europa”, grants PI14/01648 (to F.B.-V. and J.M.M.-C.) and PI18/00164(to F.B.-V.), as well as by Fundacióla Maratóde TV3 grant 20152431 (to F.B.-V.), Centro de Investigación Biomédicaen Red de Diabetes y Enfermedades Metabólicas Asociadas (CIBERDEM), and Centro de Investigación Biomédicaen Red de Fisiopatología de la Obesidad y Nutrición (CIBEROBN).

Beneficial Effects of Limosilactobacillus fermentum in the DCA Experimental Model of Irritable Bowel Syndrome in Rats
Limosilactobacillus fermentum CECT5716, a probiotic strain isolated from human milk, has
reported beneficial effects on different gastrointestinal disorders. Moreover, it has shown its ability to
restore altered immune responses, in association with microbiome modulation in different pathological
conditions. Therefore, our aim was to assess the effects of a Limosilacbacillus fermentum CECT5716
in a rat experimental model of irritable bowel syndrome (IBS) that resembles human IBS. The experimental
IBS was induced by deoxycholic acid (DCA) in rats and then, Limosilactobacillus fermentum
CECT5716 (109 CFU/day/rat) was administered. Behavioral studies, hyperalgesia and intestinal
hypersensitivity determinations were performed and the impact of the probiotic on the inflammatory
and intestinal barrier integrity was evaluated. Additionally, the gut microbiota composition was
analyzed. Limosilactobacillus fermentum CECT5716 attenuated the anxiety-like behavior as well as the
visceral hypersensitivity and referred pain. Moreover, this probiotic ameliorated the gut inflammatory
status, re-establishing the altered intestinal permeability, reducing the mast cell degranulation and
re-establishing the gut dysbiosis in experimental IBS. Therefore, our results suggest a potential use of
Limosilactobacillus fermentum CECT5716 in clinical practice for the management of IBS patients.Junta de Andalucia A-CTS-447-UGR18

Evaluation of two treatment strategies for the prevention of preterm birth in women identified as at risk by ultrasound (PESAPRO Trial): Study protocol for a randomized controlled trial
Background: Premature birth is considered one of the main problems in modern Obstetrics. It causes more than
50 % of neonatal mortality; it is responsible for a large proportion of infant morbidity and incurs very high
economic costs. Cervical length, which can be accurately measured by ultrasound, has an inverse relationship with
the risk of preterm birth. As a result, having an effective intervention for asymptomatic patients with short cervix
could reduce the prematurity. Although recently published data demonstrates the effectiveness of vaginal
progesterone and cervical pessary, these treatments have never been compared to one another.
Methods/Design: The PESAPRO study is a noncommercial, multicenter, open-label, randomized clinical trial (RCT)
in pregnant women with a short cervix as identified by transvaginal ultrasonography at 19 to 22 weeks of
gestation. Patients are randomized (1:1) to either daily vaginal progesterone or cervical pessary until the 37th week
of gestation or delivery; whichever comes first. During the trial, women visit every 4 weeks for routine questions
and tests. The primary outcome is the proportion of spontaneous preterm deliveries before 34 weeks of gestation.
A sample size of 254 pregnant women will be included at 29 participating hospitals in order to demonstrate
noninferiority of placing a pessary versus vaginal progesterone. The first patient was randomized in August 2012,
and recruitment of study subjects will continue until the end of December 2015.
Discussion: This trial assesses the comparative efficacy and safety between two accepted treatments, cervical
pessary versus vaginal progesterone, and it will provide evidence in order to establish clinical recommendationsThe study has been funded by two national grants from the Spanish Ministry
of Health and ISCIII

Impact of intestinal dysbiosis-related drugs on the efficacy of immune checkpoint inhibitors in clinical practice
[Purpose]: Intestinal dysbiosis has emerged as a biomarker of response to immune checkpoint inhibitors (ICIs). It can be caused by antibiotics, although it may also result from the use of other drugs that have been studied to a lesser extent. The objective of our study was to analyze the association between the use of potentially dysbiosis-related drugs and survival in patients treated with ICIs in the clinical practice.[Materials and methods]: A retrospective, multicenter, cohort study was conducted. Clinicopathological variables were collected and the concomitant use of drugs was analyzed. A descriptive analysis of variables and overall survival, estimated by the Kaplan–Meier method, was performed, and association with various independent variables was assessed using Cox regression.[Results]: We included 253 patients, mainly with non-small cell lung cancer and melanoma. The most commonly used drugs were acid reducers, prescribed to 55.3% of patients, followed by corticosteroids (37.9%), anxiolytic drugs (35.6%), and antibiotics (20.5%). The use of acid reducers (9 vs. 18 months, P < .0001), antibiotics (7 vs. 15 months, P < .017), anxiolytic drugs (8 vs. 16 months, P < .015), and corticosteroids (6 vs. 19 months, P < .00001) was associated with poorer overall survival. Furthermore, the greater the number of drugs used concomitantly with ICIs, the higher the risk of death (1 drug: hazard ratio, 1.88; CI 95%, 1.07–3.30; 4 drugs: hazard ratio, 4.19; CI9 5%, 1.77–9.92; P < .001).[Conclusion]: Response to ICIs may be influenced by the use of drugs that lead to intestinal dysbiosis. Although a confirmatory prospective controlled study is required, our findings should be taken into account when analyzing ICI efficacy
