    La actual problemática del cambio climático hace necesaria la búsqueda de alternativas viables para intentar paliarlo. Una de las múltiples opciones es contribuir a la reducción del CO2 atmosférico secuestrando carbono (C) en el suelo. La recuperación de espacios degradados, como los afectados por actividades extractivas, permiten incrementar el C orgánico secuestrado en el suelo al mismo tiempo que se restaura la zona. Así pues, en el presente trabajo se estudian los cambios cuantitativos y cualitativos en el C orgánico del suelo de una cantera de calizas dolomíticas rehabilitado mediante tierras enmendadas con lodos de depuradora. Concretamente, se han comparado parcelas restauradas con una mezcla de tierra y lodos de depuradora urbana con otras restauradas solo con tierra de la zona (control). Se dispone de muestras recogidas en noviembre de 1996 y otras recogidas en primavera de 2014. De estas, se ha analizado el C oxidable con dicromato de potasio (C orgánico total) y también otras formas de carbono más estables como el C no hidrolizable con ácido clorhídrico y el C insoluble en medio alcalino (huminas). Los resultados muestran que el contenido de C orgánico en las parcelas tratadas con lodos y en las parcelas de control ha aumentado significativamente pasados los dieciocho años. También se ha observado que los suelos tratados con lodos de depuradora presentan valores más altos de C no hidrolizable y de C insoluble en medio alcalino que las parcelas control. Así pues, considerando el periodo de 1996-2014, la restauración usando lodos de depuradora como enmienda del suelo ha supuesto un secuestro neto de 26 Mg C · ha–1 en comparación con los 19 Mg C · ha–1 en el suelo de control. Por lo tanto, se puede afirmar que la aplicación de lodos puede contribuir a acelerar y aumentar el secuestro de C en suelos restaurados en los que se han llevado a cabo actividades extractivas.The current issue of climate change requires a search for viable alternatives to try to alleviate it. One of the many options is to contribute to the reduction of atmospheric CO2 sequestering carbon (C) in the soil. Rehabilitation of degraded areas, such as those affected by mining activities, increases the amount of organic C sequestered in the soil when these areas are recovered. In this paper, quantitative and qualitative changes over a period of 18 years in soil organic C of a dolomitic limestone quarry are presented. This site was partially rehabilitated by using a mixture of the local (control) soil amended with sewage sludge or soil alone. The study compares samples collected in November 1996 and others in the spring of 2014. Of these, the C oxidizable with potassium dichromate (total organic C) and other more stable C fractions, such as C non-hydrolysable with hydrochloric acid and C insoluble in alkaline media (humin), were analyzed. The results show that the content of organic C in sludge-treated plots and control plots has increased significantly after 18 years. It has also been observed that the sewage sludge-treated soils have higher values of insoluble C and recalcitrant C than the control plots. Thus, considering the period 1996-2014, soil rehabilitation using sewage sludge represents a net sequestration of 26 MgC·ha-1 compared to 19 MgC·ha-1 in the control plots. Therefore, the application of sewage sludge can help to accelerate and to increase carbon sequestration in soils of rehabilitated mining sites.La problemàtica actual del canvi climàtic fa necessària la recerca d'alternatives viables per a intentar pal·liar-lo. Una de les múltiples opcions és contribuir a la reducció del CO2 atmosfèric segrestant carboni (C) en el sòl. La recuperació d'àrees degradades, com les afectades per activitats extractives, pot permetre incrementar el C orgànic segrestat en el sòl al mateix temps que es restaura la zona. En aquest treball s'han estudiat els canvis quantitatius i qualitatius, en divuit anys, del C orgànic del sòl en una pedrera de calcàries dolomítiques rehabilitat mitjançant terres adobades amb fangs de depuradora. Concretament, s'han comparat parcel·les adobades amb una mescla de terra i fangs de depuradora urbana amb d'altres de restaurades només amb terra de la zona (control). Es disposa de mostres agafades el novembre de l'any 1996, un mes després de l'estesa de les terres, i d'altres de la primavera del 2014. S'ha analitzat el C oxidable amb dicromat de potassi (C orgànic total) i també altres formes més estables del carboni, com el C no hidrolitzable amb àcid clorhídric i el C insoluble en medi alcalí (humines). Els resultats mostren que el contingut de C orgànic ha augmentat significativament passats divuit anys tant en parcel·les tractades amb fangs de depuradora com en les parcel·les de control. També s'ha observat que els sòls tractats amb fangs presenten valors més elevats de C no hidrolitzable i de C insoluble en medi alcalí que les parcel·les de control. Així doncs, considerant el període 1996-2014, la restauració usant fangs de depuradora com a esmena del sòl ha suposat un segrest net de 26 Mg C · ha–1en comparació dels 19 Mg C · ha–1 en el sòl de control. Per tant, es pot afirmar que l'aplicació de fangs pot contribuir a accelerar i augmentar el segrest de C en sòls restaurats que han sofert activitats extractives

We thank FIC-Fundacion Jesús Serra, Barcelona, Spain, for their continuous support.Background: The composition and function of the adipose tissue covering the heart are poorly known. In this study, we have investigated the epicardial adipose tissue (EAT) covering the cardiac ventricular muscle and the EAT covering the left anterior descending artery (LAD) on the human heart, to identify their resident stem cell functional activity. Methods: EAT covering the cardiac ventricular muscle was isolated from the apex (avoiding areas irrigated by major vessels) of the heart (ventricular myocardium adipose tissue (VMAT)) and from the area covering the epicardial arterial sulcus of the LAD (PVAT) in human hearts excised during heart transplant surgery. Adipose stem cells (ASCs) from both adipose tissue depots were immediately isolated and phenotypically characterized by flow cytometry. The different behavior of these ASCs and their released secretome microvesicles (MVs) were investigated by molecular and cellular analysis. Results: ASCs from both VMAT (mASCs) and the PVAT (pASCs) were characterized by the expression of CD105, CD44, CD29, CD90, and CD73. The angiogenic-related genes VEGFA, COL18A1, and TF, as well as the miRNA126-3p and miRNA145-5p, were analyzed in both ASC types. Both ASCs were functionally able to form tube-like structures in three-dimensional basement membrane substrates. Interestingly, pASCs showed a higher level of expression of VEGFA and reduced level of COL18A1 than mASCs. Furthermore, MVs released by mASCs significantly induced human microvascular endothelial cell migration. Conclusion: Our study indicates for the first time that the resident ASCs in human epicardial adipose tissue display a depot-specific angiogenic function. Additionally, we have demonstrated that resident stem cells are able to regulate microvascular endothelial cell function by the release of MVs

    BACKGROUND: Dissociative seizures are paroxysmal events resembling epilepsy or syncope with characteristic features that allow them to be distinguished from other medical conditions. We aimed to compare the effectiveness of cognitive behavioural therapy (CBT) plus standardised medical care with standardised medical care alone for the reduction of dissociative seizure frequency. METHODS: In this pragmatic, parallel-arm, multicentre randomised controlled trial, we initially recruited participants at 27 neurology or epilepsy services in England, Scotland, and Wales. Adults (≥18 years) who had dissociative seizures in the previous 8 weeks and no epileptic seizures in the previous 12 months were subsequently randomly assigned (1:1) from 17 liaison or neuropsychiatry services following psychiatric assessment, to receive standardised medical care or CBT plus standardised medical care, using a web-based system. Randomisation was stratified by neuropsychiatry or liaison psychiatry recruitment site. The trial manager, chief investigator, all treating clinicians, and patients were aware of treatment allocation, but outcome data collectors and trial statisticians were unaware of treatment allocation. Patients were followed up 6 months and 12 months after randomisation. The primary outcome was monthly dissociative seizure frequency (ie, frequency in the previous 4 weeks) assessed at 12 months. Secondary outcomes assessed at 12 months were: seizure severity (intensity) and bothersomeness; longest period of seizure freedom in the previous 6 months; complete seizure freedom in the previous 3 months; a greater than 50% reduction in seizure frequency relative to baseline; changes in dissociative seizures (rated by others); health-related quality of life; psychosocial functioning; psychiatric symptoms, psychological distress, and somatic symptom burden; and clinical impression of improvement and satisfaction. p values and statistical significance for outcomes were reported without correction for multiple comparisons as per our protocol. Primary and secondary outcomes were assessed in the intention-to-treat population with multiple imputation for missing observations. This trial is registered with the International Standard Randomised Controlled Trial registry, ISRCTN05681227, and ClinicalTrials.gov, NCT02325544. FINDINGS: Between Jan 16, 2015, and May 31, 2017, we randomly assigned 368 patients to receive CBT plus standardised medical care (n=186) or standardised medical care alone (n=182); of whom 313 had primary outcome data at 12 months (156 [84%] of 186 patients in the CBT plus standardised medical care group and 157 [86%] of 182 patients in the standardised medical care group). At 12 months, no significant difference in monthly dissociative seizure frequency was identified between the groups (median 4 seizures [IQR 0-20] in the CBT plus standardised medical care group vs 7 seizures [1-35] in the standardised medical care group; estimated incidence rate ratio [IRR] 0·78 [95% CI 0·56-1·09]; p=0·144). Dissociative seizures were rated as less bothersome in the CBT plus standardised medical care group than the standardised medical care group (estimated mean difference -0·53 [95% CI -0·97 to -0·08]; p=0·020). The CBT plus standardised medical care group had a longer period of dissociative seizure freedom in the previous 6 months (estimated IRR 1·64 [95% CI 1·22 to 2·20]; p=0·001), reported better health-related quality of life on the EuroQoL-5 Dimensions-5 Level Health Today visual analogue scale (estimated mean difference 6·16 [95% CI 1·48 to 10·84]; p=0·010), less impairment in psychosocial functioning on the Work and Social Adjustment Scale (estimated mean difference -4·12 [95% CI -6·35 to -1·89]; p<0·001), less overall psychological distress than the standardised medical care group on the Clinical Outcomes in Routine Evaluation-10 scale (estimated mean difference -1·65 [95% CI -2·96 to -0·35]; p=0·013), and fewer somatic symptoms on the modified Patient Health Questionnaire-15 scale (estimated mean difference -1·67 [95% CI -2·90 to -0·44]; p=0·008). Clinical improvement at 12 months was greater in the CBT plus standardised medical care group than the standardised medical care alone group as reported by patients (estimated mean difference 0·66 [95% CI 0·26 to 1·04]; p=0·001) and by clinicians (estimated mean difference 0·47 [95% CI 0·21 to 0·73]; p<0·001), and the CBT plus standardised medical care group had greater satisfaction with treatment than did the standardised medical care group (estimated mean difference 0·90 [95% CI 0·48 to 1·31]; p<0·001). No significant differences in patient-reported seizure severity (estimated mean difference -0·11 [95% CI -0·50 to 0·29]; p=0·593) or seizure freedom in the last 3 months of the study (estimated odds ratio [OR] 1·77 [95% CI 0·93 to 3·37]; p=0·083) were identified between the groups. Furthermore, no significant differences were identified in the proportion of patients who had a more than 50% reduction in dissociative seizure frequency compared with baseline (OR 1·27 [95% CI 0·80 to 2·02]; p=0·313). Additionally, the 12-item Short Form survey-version 2 scores (estimated mean difference for the Physical Component Summary score 1·78 [95% CI -0·37 to 3·92]; p=0·105; estimated mean difference for the Mental Component Summary score 2·22 [95% CI -0·30 to 4·75]; p=0·084), the Generalised Anxiety Disorder-7 scale score (estimated mean difference -1·09 [95% CI -2·27 to 0·09]; p=0·069), and the Patient Health Questionnaire-9 scale depression score (estimated mean difference -1·10 [95% CI -2·41 to 0·21]; p=0·099) did not differ significantly between groups. Changes in dissociative seizures (rated by others) could not be assessed due to insufficient data. During the 12-month period, the number of adverse events was similar between the groups: 57 (31%) of 186 participants in the CBT plus standardised medical care group reported 97 adverse events and 53 (29%) of 182 participants in the standardised medical care group reported 79 adverse events. INTERPRETATION: CBT plus standardised medical care had no statistically significant advantage compared with standardised medical care alone for the reduction of monthly seizures. However, improvements were observed in a number of clinically relevant secondary outcomes following CBT plus standardised medical care when compared with standardised medical care alone. Thus, adults with dissociative seizures might benefit from the addition of dissociative seizure-specific CBT to specialist care from neurologists and psychiatrists. Future work is needed to identify patients who would benefit most from a dissociative seizure-specific CBT approach.

    Background Dissociative (non-epileptic) seizures are potentially treatable by psychotherapeutic interventions; however, the evidence for this is limited. Objectives To evaluate the clinical effectiveness and cost-effectiveness of dissociative seizure-specific cognitive–behavioural therapy for adults with dissociative seizures. Design This was a pragmatic, multicentre, parallel-arm, mixed-methods randomised controlled trial. Setting This took place in 27 UK-based neurology/epilepsy services, 17 liaison psychiatry/neuropsychiatry services and 18 cognitive–behavioural therapy services. Participants Adults with dissociative seizures in the previous 8 weeks and no epileptic seizures in the previous year and meeting other eligibility criteria were recruited to a screening phase from neurology/epilepsy services between October 2014 and February 2017. After psychiatric assessment around 3 months later, eligible and interested participants were randomised between January 2015 and May 2017. Interventions Standardised medical care consisted of input from neurologists and psychiatrists who were given guidance regarding diagnosis delivery and management; they provided patients with information booklets. The intervention consisted of 12 dissociative seizure-specific cognitive–behavioural therapy 1-hour sessions (plus one booster session) that were delivered by trained therapists, in addition to standardised medical care. Main outcome measures The primary outcome was monthly seizure frequency at 12 months post randomisation. The secondary outcomes were aspects of seizure occurrence, quality of life, mood, anxiety, distress, symptoms, psychosocial functioning, clinical global change, satisfaction with treatment, quality-adjusted life-years, costs and cost-effectiveness. Results In total, 698 patients were screened and 368 were randomised (standardised medical care alone, n = 182; and cognitive–behavioural therapy plus standardised medical care, n = 186). Primary outcome data were obtained for 85% of participants. An intention-to-treat analysis with multivariate imputation by chained equations revealed no significant between-group difference in dissociative seizure frequency at 12 months [standardised medical care: median of seven dissociative seizures (interquartile range 1–35 dissociative seizures); cognitive–behavioural therapy and standardised medical care: median of four dissociative seizures (interquartile range 0–20 dissociative seizures); incidence rate ratio 0.78, 95% confidence interval 0.56 to 1.09; p = 0.144]. Of the 16 secondary outcomes analysed, nine were significantly better in the arm receiving cognitive–behavioural therapy at a p-value &lt; 0.05, including the following at a p-value ≤ 0.001: the longest dissociative seizure-free period in months 7–12 inclusive post randomisation (incidence rate ratio 1.64, 95% confidence interval 1.22 to 2.20; p = 0.001); better psychosocial functioning (Work and Social Adjustment Scale, standardised treatment effect –0.39, 95% confidence interval –0.61 to –0.18; p &lt; 0.001); greater self-rated and clinician-rated clinical improvement (self-rated: standardised treatment effect 0.39, 95% confidence interval 0.16 to 0.62; p = 0.001; clinician rated: standardised treatment effect 0.37, 95% confidence interval 0.17 to 0.57; p &lt; 0.001); and satisfaction with treatment (standardised treatment effect 0.50, 95% confidence interval 0.27 to 0.73; p &lt; 0.001). Rates of adverse events were similar across arms. Cognitive–behavioural therapy plus standardised medical care produced 0.0152 more quality-adjusted life-years (95% confidence interval –0.0106 to 0.0392 quality-adjusted life-years) than standardised medical care alone. The incremental cost-effectiveness ratio (cost per quality-adjusted life-year) for cognitive–behavioural therapy plus standardised medical care versus standardised medical care alone based on the EuroQol-5 Dimensions, five-level version, and imputed data was £120,658. In sensitivity analyses, incremental cost-effectiveness ratios ranged between £85,724 and £206,067. Qualitative and quantitative process evaluations highlighted useful study components, the importance of clinical experience in treating patients with dissociative seizures and potential benefits of our multidisciplinary care pathway. Limitations Unlike outcome assessors, participants and clinicians were not blinded to the interventions. Conclusions There was no significant additional benefit of dissociative seizure-specific cognitive–behavioural therapy in reducing dissociative seizure frequency, and cost-effectiveness over standardised medical care was low. However, this large, adequately powered, multicentre randomised controlled trial highlights benefits of adjunctive dissociative seizure-specific cognitive–behavioural therapy for several clinical outcomes, with no evidence of greater harm from dissociative seizure-specific cognitive–behavioural therapy.

    P20 Introduction: Psoriasis is a chronic skin disease with negative physical, mental and social manifestations. Method: We carried out a longitudinal and prospective study under routine clinical practice conditions. The objective of the study was to measure quality of life with the Short Form-36 Survey (SF-36) and correlate the results with clinical variables using the PASI and BSA in a group of 17 patients with moderate to severe psoriasis treated with Ustekinumab. Results: In the baseline evaluation we observed the following results: 35.3% reported physical malfunction, 64.7% debilitating pain, 82.3% poor health in general, 76.4% bad vitality, 88.2% social malfunction, 100% emotional malfunction and 82.3% poor mental health. At week 78 we observed the following results: 41.15% reported very good physical functioning, 76.1% no pain, 58.8% good general health, 58.8% very good vitality, 70%, 5% good social functioning, 70.5% good emotional functioning and 52.9% good mental health. Conclusion: We observed that the perception of patients with moderate-severe psoriasis regarding their health at the beginning of treatment with Ustekinumab was poor and that they experienced a significant improvement throughout the successive weeks of treatment

    Feasibility, clinical efficacy, and well-being outcomes of an online singing intervention for postnatal depression in the UK: SHAPER-PNDO, a single-arm clinical trial

    BACKGROUND: Postnatal depression (PND) affects over 12% of mothers, with numbers rising during COVID-19. Singing groups can support mothers with PND; however, online delivery has never been evaluated. SHAPER-PNDO, a single-arm clinical trial, evaluated the feasibility, clinical efficacy, and well-being outcomes of a 6-week online version of Breathe Melodies for Mums (M4M) singing intervention developed for mothers with PND during COVID-19 lockdowns. METHODS: The primary objective of this study was to assess the feasibility of a group online singing intervention for new mothers with postnatal depression. This was ascertained through recruitment rates, study retention rates, attendance rates to the singing sessions, and study completion rates. The secondary objective of the study was to assess the clinical efficacy and well-being outcomes of the singing intervention. Specifically, we measured change in Edinburgh Postnatal Depression Scale (EPDS), State-Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS), and Office for National Statistics Wellbeing Scale (ONS) scores from baseline to end-of-intervention (week 6); follow-up assessments were completed at weeks 3, 16, and 32. Mothers were eligible if they scored ≥10 on the baseline EPDS. RESULTS: Eighty-seven percent of the 37 recruited mothers completed the study, attending, on average, 5 of the 6 group singing sessions. With regard to secondary outcomes, at end-of-treatment, mothers experienced significant reductions in depression (EPDS, 16.6 ± 3.7 to 11.2 ± 5.3, 95% CI [0.79,1.65]), anxiety (STAI-S, 48.4 ± 27.1 to 41.7 ± 26.8, 95% CI [4.96, 17.65]) and stress (PSS, 29.0 ± 5.7 to 19.7 ± 5.3, 95% CI [1.33, 7.07]); and, furthermore, significant improvements in life satisfaction (ONS, 50.5 ± 23.0 to 72.8 ± 11.7, 95% CI [- 39.86, - 4.64]) and feelings of worthwhileness (ONS, 51.7 ± 30.4 to 78.6 ± 15.1, 95% CI [- 52.79, - 0.85]). Reduction on the EPDS correlated with a reduction on the BDI and the STAI-S and maternal childhood maltreatment was predictive of a smaller treatment response. CONCLUSIONS: M4M online was feasible to mothers who partook in the programme. Furthermore, M4M online supports the mental health and well-being of new mothers experiencing PND, especially when barriers to in-person treatment are present
