1.	Perez-Nadales, Elena, et al. (författare) Predictors of mortality in solid organ transplant recipients with bloodstream infections due to carbapenemase-producing Enterobacterales : The impact of cytomegalovirus disease and lymphopenia 2020 Ingår i: American Journal of Transplantation. - : WILEY. - 1600-6135 .- 1600-6143. ; 20:6, s. 1629-1641 Tidskriftsartikel (refereegranskat)abstract Treatment of carbapenemase-producing Enterobacterales bloodstream infections in solid organ transplant recipients is challenging. The objective of this study was to develop a specific score to predict mortality in solid organ transplant recipients with carbapenemase-producing Enterobacterales bloodstream infections. A multinational, retrospective (2004-2016) cohort study (INCREMENT-SOT, ClinicalTrials.gov NCT02852902) was performed. The main outcome variable was 30-day all-cause mortality. The INCREMENT-SOT-CPE score was developed using logistic regression. The global cohort included 216 patients. The final logistic regression model included the following variables: INCREMENT-CPE mortality score >= 8 (8 points), no source control (3 points), inappropriate empirical therapy (2 points), cytomegalovirus disease (7 points), lymphopenia (4 points), and the interaction between INCREMENT-CPE score >= 8 and CMV disease (minus 7 points). This score showed an area under the receiver operating characteristic curve of 0.82 (95% confidence interval [CI] 0.76-0.88) and classified patients into 3 strata: 0-7 (low mortality), 8-11 (high mortality), and 12-17 (very-high mortality). We performed a stratified analysis of the effect of monotherapy vs combination therapy among 165 patients who received appropriate therapy. Monotherapy was associated with higher mortality only in the very-high (adjusted hazard ratio [HR] 2.82, 95% CI 1.13-7.06, P = .03) and high (HR 9.93, 95% CI 2.08-47.40, P = .004) mortality risk strata. A score-based algorithm is provided for therapy guidance.

5.	Householder, John Ethan, et al. (författare) One sixth of Amazonian tree diversity is dependent on river floodplains 2024 Ingår i: NATURE ECOLOGY & EVOLUTION. - 2397-334X. Tidskriftsartikel (refereegranskat)abstract Amazonia's floodplain system is the largest and most biodiverse on Earth. Although forests are crucial to the ecological integrity of floodplains, our understanding of their species composition and how this may differ from surrounding forest types is still far too limited, particularly as changing inundation regimes begin to reshape floodplain tree communities and the critical ecosystem functions they underpin. Here we address this gap by taking a spatially explicit look at Amazonia-wide patterns of tree-species turnover and ecological specialization of the region's floodplain forests. We show that the majority of Amazonian tree species can inhabit floodplains, and about a sixth of Amazonian tree diversity is ecologically specialized on floodplains. The degree of specialization in floodplain communities is driven by regional flood patterns, with the most compositionally differentiated floodplain forests located centrally within the fluvial network and contingent on the most extraordinary flood magnitudes regionally. Our results provide a spatially explicit view of ecological specialization of floodplain forest communities and expose the need for whole-basin hydrological integrity to protect the Amazon's tree diversity and its function.
6.	Luize, Bruno Garcia, et al. (författare) Geography and ecology shape the phylogenetic composition of Amazonian tree communities 2024 Ingår i: JOURNAL OF BIOGEOGRAPHY. - 0305-0270 .- 1365-2699. Tidskriftsartikel (refereegranskat)abstract Aim: Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location: Amazonia. Taxon: Angiosperms (Magnoliids; Monocots; Eudicots). Methods: Data for the abundance of 5082 tree species in 1989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran's eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped associations onto the phylogeny. Results: In the terra firme and v & aacute;rzea forest types, the phylogenetic composition varies by geographic region, but the igap & oacute; and white-sand forest types retain a unique evolutionary signature regardless of region. Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R-2 = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R-2 = 28%). A greater number of lineages were significant indicators of geographic regions than forest types. Main Conclusion: Numerous tree lineages, including some ancient ones (>66 Ma), show strong associations with geographic regions and edaphic forest types of Amazonia. This shows that specialization in specific edaphic environments has played a long-standing role in the evolutionary assembly of Amazonian forests. Furthermore, many lineages, even those that have dispersed across Amazonia, dominate within a specific region, likely because of phylogenetically conserved niches for environmental conditions that are prevalent within regions.
7.	ter Steege, Hans, et al. (författare) Mapping density, diversity and species-richness of the Amazon tree flora 2023 Ingår i: COMMUNICATIONS BIOLOGY. - 2399-3642. ; 6:1 Tidskriftsartikel (refereegranskat)abstract Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness. Using only location, stratified by forest type, as predictor, our spatial model, to the best of our knowledge, provides the most accurate map of tree diversity in Amazonia to date, explaining approximately 70% of the tree diversity and species-richness. Large soil-forest combinations determine a significant percentage of the variation in tree species-richness and tree alpha-diversity in Amazonian forest-plots. We suggest that the size and fragmentation of these systems drive their large-scale diversity patterns and hence local diversity. A model not using location but cumulative water deficit, tree density, and temperature seasonality explains 47% of the tree species-richness in the terra-firme forest in Amazonia. Over large areas across Amazonia, residuals of this relationship are small and poorly spatially structured, suggesting that much of the residual variation may be local. The Guyana Shield area has consistently negative residuals, showing that this area has lower tree species-richness than expected by our models. We provide extensive plot meta-data, including tree density, tree alpha-diversity and tree species-richness results and gridded maps at 0.1-degree resolution. A study mapping the tree species richness in Amazonian forests shows that soil type exerts a strong effect on species richness, probably caused by the areas of these forest types. Cumulative water deficit, tree density and temperature seasonality affect species richness at a regional scale.
8.	Ferreira, N., et al. (författare) The impact of the coronavirus (COVID-19) pandemic on individuals with gastrointestinal disorders: A protocol of an international collaborative study 2021 Ingår i: Journal of Psychosomatic Research. - : Elsevier BV. - 0022-3999 .- 1879-1360. ; 148 Tidskriftsartikel (refereegranskat)abstract Objective: The COVID-19 pandemic has had a significant impact on mental health across the globe. People living with a chronic gastrointestinal (GI) disorder might be particularly at risk of mental health complications given higher rates of comorbid anxiety and depression compared to the healthy population. As GI disorders affect up to 40% of the population worldwide, this international collaborative study seeks to evaluate the extent of the impact of the COVID-19 pandemic on GI symptoms specifically and more generally on the well-being of those living with chronic GI conditions. Methods: A longitudinal survey with three time points (baseline, 6-month, and 12-month) will be conducted online. Adult participants with GI disorders from multiple countries will be recruited via patient associations, social media advertising, utilizing snowball sampling. Participants will be invited to complete a battery of questionnaires including demographic and health parameters, and measures of gastrointestinal symptoms, fear of COVID-19, perceived impact of COVID-19, illness perceptions, coping, depression, anxiety, stress, catastroph-izing, and quality of life, using validated measures where available. Statistical analyses will include univariate descriptive models, multivariate models utilizing regression, mediation, and moderation, and latent growth models. Conclusions: This project may present novel information to the field of psychogastroenterology and may provide crucial information regarding the areas of impact for individuals with GI disorders during and following the pandemic. Further, this information can guide healthcare providers and patient associations on how to target support related to the pandemic mental health sequelae for these patients.

10.	Peripato, Vinicius, et al. (författare) More than 10,000 pre-Columbian earthworks are still hidden throughout Amazonia 2023 Ingår i: Science (New York, N.Y.). - 1095-9203. ; 382:6666, s. 103-109 Tidskriftsartikel (refereegranskat)abstract Indigenous societies are known to have occupied the Amazon basin for more than 12,000 years, but the scale of their influence on Amazonian forests remains uncertain. We report the discovery, using LIDAR (light detection and ranging) information from across the basin, of 24 previously undetected pre-Columbian earthworks beneath the forest canopy. Modeled distribution and abundance of large-scale archaeological sites across Amazonia suggest that between 10,272 and 23,648 sites remain to be discovered and that most will be found in the southwest. We also identified 53 domesticated tree species significantly associated with earthwork occurrence probability, likely suggesting past management practices. Closed-canopy forests across Amazonia are likely to contain thousands of undiscovered archaeological sites around which pre-Columbian societies actively modified forests, a discovery that opens opportunities for better understanding the magnitude of ancient human influence on Amazonia and its current state.

This online cross-sectional survey was advertised in May-September 2020 via patient organisations and associated social media. Overall, 831 people (82% female, mean age 49 years) from 27 countries participated. A significant relationship between social isolation and psychological distress was noted (r = .525, p < .001). GI symptoms moderated the association between isolation and distress (B = .047, t = 2.47, p = .015). Interventions targeting these factors may help to reduce distress in people with GI disorders at the time of major stressors such as the COVID-19 pandemic.
14.	Schiffer, Christian, et al. (författare) Vp/Vs ratios in the Parnaíba Basin from joint active-passive seismic analysis : Implications for continental amalgamation and basin formation 2021 Ingår i: Tectonophysics. - : Elsevier. - 0040-1951 .- 1879-3266. ; 801 Tidskriftsartikel (refereegranskat)abstract The Phanerozoic intracontinental Parnaíba Basin in northeast Brazil lies atop crust composed of Archaean to Mesoproterozoic cratonic blocks and Neoproterozoic mobile belts. Recently, active and passive source geophysical surveys characterised the crustal structure beneath the basin. We use information from published active-source seismic and new, coincident receiver function (RF) data to obtain Vp/Vs ratios for sedimentary and crustal structure and make inferences about crustal compositions and tectonic evolution. In our approach, sedimentary and crustal Vp/Vs ratios are adjusted to match common conversion point (CCP) images of RFs and known Moho and basement geometry. We use a P-wave model from published wide-angle reflection/refraction (WARR) seismics, and structural features from a deep seismic reflection (DSR) profile. CCP images of the primary RF conversions were used to model the crust, whilst conversions of multiples were used for the sediment-basement interface. The maximum uncertainties in Vp/Vs are estimated to be 0.15 for the basin and 0.03 for the crust. Vp/Vs ratios in the basin were estimated between 1.7 and 2.2. Lower values correlate with the exposure of older units primarily in the east of the basin, whilst higher values coincide with exposed younger units of the Parnaíba Basin. The obtained crustal Vp/Vs ratios between 1.73 and 1.81 support the previously published segmentation of the crust. In particular, we identified three regions of elevated Vp/Vs ratios, which can be related to proposed Neoproterozoic suture zones underlying the Parnaíba Basin, as well as high velocity lower crust beneath. The high Vp/Vs ratios can be explained by mafic compositions, for example metamorphosed or intruded crust, or fluids and sedimentary rocks entrained into highly deformed crust, typical for modifications related to suture zones. These new deep geophysical models provide important and complementary evidence for crustal amalgamation and the formation of the Parnaíba Basin.
15.	Biscaia, S. M. P., et al. (författare) Safe therapeutics of murine melanoma model using a novel antineoplasic, the partially methylated mannogalactan from Pleurotus eryngii 2017 Ingår i: Carbohydrate Polymers. - : ELSEVIER SCI LTD. - 0144-8617 .- 1879-1344. ; 178, s. 95-104 Tidskriftsartikel (refereegranskat)abstract A heteropolysaccharide was isolated by cold aqueous extraction from edible mushroom Pleurotus eryngii ("King Oyster") basidiocarps and its biological properties were evaluated. Structural assignments were carried out using mono-and bidimensional NMR spectroscopy, monosaccharide composition, and methylation analyses. A man-nogalactan having a main chain of (1 -> 6)-linked alpha-D-galactopyranosyl and 3-O-methyl-alpha-D-galactopyranosyl residues, both partially substituted at OH-2 by beta-D-Manp (MG-Pe) single-unit was found. Biological effects of mannogalactan from P. eryngii (MG-Pe) were tested against murine melanoma cells. MG-Pe was non-cytotoxic, but reduced in vitro melanoma cells invasion. Also, 50 mg/kg MG-Pe administration to melanoma-bearing C57BL/6 mice up to 10 days decreased in 60% the tumor volume compared to control. Additionally, no changes were observed when biochemical profile, complete blood cells count (CBC), organs, and body weight were analyzed. Mg-Pe was shown to be a promising anti-melanoma molecule capable of switching melanoma cells to a non-invasive phenotype with no toxicity to melanoma-bearing mice.
16.	Bispo-Santos, Franklin, et al. (författare) Columbia revisited : paleomagnetic results from the 1790 Ma colider volcanics (SW Amazonian Craton, Brazil) 2008 Ingår i: Precambrian Research. - : Elsevier BV. - 0301-9268 .- 1872-7433. ; 164:1-2, s. 40-49 Tidskriftsartikel (refereegranskat)abstract In an attempt to improve our understanding of the Paleoproterozoic geodynamic evolution, a paleomagnetic study was performed on 10 sites of acid volcanic rocks of the Colider Suite, southwestern Amazonian Craton. These rocks have a well-dated zircon U-Pb mean age of 1789 +/- 7 Ma. Alternating field and thermal demagnetization revealed northern (southern) directions with moderate to high upward (downward) inclinations. Rock magnetism experiments and magnetic mineralogy show that this characteristic magnetization is carried by Ti-poor magnetite or by hematite that replaces magnetite by late-magmatic cleuteric alteration. Both magnetite and hematite carry the same characteristic component. The mean direction (Dm = 183.0 degrees, Im = 53.5 degrees, N = 10, alpha(95) = 9.8 degrees, K = 25.2) yielded a paleomagnetic pole located at 298.8 degrees E, 63.3 degrees S (alpha(95) = 10.2 degrees, K = 23.6), which is classified with a quality factor Q = 5. Paleogeographic reconstructions using this pole and other reliable Paleoproterozoic poles suggest that Laurentia, Baltica, North China Craton and Amazonian Craton were located in laterally contiguous positions forming a large continental mass at 1790 Ma ago. This is reinforced by geological evidence which support the existence of the supercontinent Columbia in Paleoproterozoic times.
17.	Bispo-Santos, Franklin, et al. (författare) Tectonic implications of the 1419 Ma Nova Guarita mafic intrusives paleomagnetic pole (Amazonian Craton) on the longevity of Nuna 2012 Ingår i: Precambrian Research. - : Elsevier BV. - 0301-9268 .- 1872-7433. ; 196-197, s. 1-22 Tidskriftsartikel (refereegranskat)abstract The Nuna supercontinent was probably assembled in the Paleoproterozoic, but its paleogeography and the timing for its demise are still a matter of debate. A paleomagnetic and geochronological study carried out on the Mesoproterozoic Nova Guarita dyke swarm (northern Mato Grosso State, SW Amazonian Craton) provides additional constraints on the duration of this supercontinent. Paleomagnetic AF and thermal treatment revealed south/southwest (northeast) magnetic directions with downward (upward) inclinations for nineteen analyzed sites. These directions are carried by PSD magnetite with high unblocking temperatures as indicated by additional magnetic tests, including thermomagnetic curves, hysteresis loops and the progressive acquisition of isothermal remanence in selected samples. A positive contact test with the host granite in one of the studied dykes further attests to the primary origin of the characteristic magnetic component. A mean site direction was calculated at Dm = 220.5°, Im = 45.9° (α95 = 6.5°, K = 27.7), which yielded a paleomagnetic pole located at 245.9°E, 47.9°S (A95 = 7.0°). 40Ar/39Ar dating carried out on biotites from four analyzed dykes yielded well-defined plateau ages with a mean of 1418.5 ± 3.5 Ma. The Nova Guarita pole precludes a long-lived Nuna configuration in which Laurentia, Baltica, North China, and Amazonia formed a long and continuous block as previously proposed for the Paleoproterozoic. It is nevertheless fully compatible with a SAMBA (Amazonia-Baltica) link at Mesoproterozoic times.
18.	Carvalho, Sérgio A., et al. (författare) Cognitive fusion and depressive symptoms in women with chronic pain : A longitudinal growth curve modelling study over 12 months 2019 Ingår i: Clinical Psychology and Psychotherapy. - : John Wiley & Sons. - 1063-3995 .- 1099-0879. ; 26:5, s. 616-625 Tidskriftsartikel (refereegranskat)abstract This study aims to (a) explore individual differences in women with chronic pain (CP) in regard to pain intensity, functional impairment, cognitive fusion, and depressive symptoms and (b) longitudinally test whether cognitive fusion is a significant predictor of depression symptoms, while controlling for pain intensity and functional impairment, over a 12-month period. This study follows a longitudinal design and was conducted in a sample of 86 women with CP who responded to an online battery of questionnaires in three equally spaced assessment moments. In order to explore the growth trajectory of variables of interest, latent growth curve models were examined. Also, correlation analyses were conducted between demographic and illness-related variables and depressive symptoms, as well as between all variables in all assessment moments. Cognitive fusion and functional impairment (but not pain intensity) were significantly associated with baseline levels of depressive symptoms. Cognitive fusion significantly predicted the growth trajectory of depressive symptoms, whereas pain intensity and functional impairment did not. No demographic (age, marital status, education, socio-economic) nor illness-related variables (number of CP diagnoses, duration of CP, taking medication) were associated with depressive symptoms at any point. These results suggest that the trajectory of depressive symptoms in women with CP is not predicted by the intensity of pain nor pain-related functional impairment, but rather by the tendency to get entangled with internal experiences (e.g., thoughts, emotions, and physical sensations), which may or may not be related to pain-specific contents. Clinical implications are discussed.
19.	Carvalho, Sérgio A., et al. (författare) Efficacy of an ACT and Compassion-Based eHealth Program for Self-Management of Chronic Pain (iACTwithPain) : Study Protocol for a Randomized Controlled Trial 2021 Ingår i: Frontiers in Psychology. - : Frontiers Media S.A.. - 1664-1078. ; 12 Tidskriftsartikel (refereegranskat)abstract Background: Chronic pain (CP) has serious medical and social consequences and leads to economic burden that threatens the sustainability of healthcare services. Thus, optimized management of pain tools to support CP patients in adjusting to their condition and improving their quality of life is timely. Although acceptance and commitment therapy (ACT) is considered an evidence-based psychological approach for CP, evidence for the efficacy of online-delivered ACT for CP is still scarce. At the same time, studies suggest that self-compassion mediates the change in disability and psychopathological symptoms in ACT interventions for CP, although self-compassion is not a specific target in ACT. Thus, an explicit focus on self-compassion might increase the efficacy of ACT interventions for CP, although this hypothesis has not been tested. This study aims to develop an eHealth ACT and compassion-based self-management intervention for CP, the iACTwithPain, and to compare its efficacy in improving health outcomes to a similar ACT-only intervention and a medical TAU group.Methods: The eHealth platform that will host the interventions will be developed using a flat design identity and will be interactive. The iACTwithPain intervention will comprise eight weekly self-management sessions and will be developed taking into consideration the psychological flexibility model applied to CP, with the addition of explicit compassion-based components. To analyze whether the iACTwithPain intervention will present superiority in improving CP's impact and related health markers over the two other conditions, this study will follow an RCT design with three arms. CP patients will be recruited through direct contact with patient associations and healthcare services and a national press release in Portugal. Outcome measurement will be conducted at baseline, post-intervention and at 3- and 6-month follow-ups. The interventions' acceptability will also be assessed.Discussion: The iACTwithPain intervention is expected to improve CP patients' psychosocial functioning, quality of life, and empowerment, by promoting adaptive disease management and regulation of pain-related internal experiences. Results will contribute to a better understanding on the pertinence of adding compassion elements to ACT for CP and to reach an optimized intervention for CP.
20.	Carvalho, Sérgio A., et al. (författare) Self-Compassion and Depressive Symptoms in Chronic Pain (CP) : A 1-Year Longitudinal Study 2020 Ingår i: Mindfulness. - : Springer. - 1868-8527 .- 1868-8535. ; 11:3, s. 709-719 Tidskriftsartikel (refereegranskat)abstract Objectives: Self-compassion is associated with less depressive symptoms, better mental health outcomes, and less disability in chronic pain (CP). However, it remains longitudinally unexplored the role of self-compassion in CP. Also, although it acknowledged the conceptual overlapping between mindfulness and self-compassion, few studies have explored the role of self-compassion in CP while controlling for mindfulness in a longitudinal design.Methods: The current study conducts correlational and hierarchical linear regression analyses in a sample of 86 women with CP who completed an online battery of questionnaires that assess pain intensity, functional impairment, depressive symptoms, mindfulness, and self-compassion in three time points: baseline (T0), 6 months (T1), and 12 months (T2).Results: Results show that self-compassion (but not mindfulness) significantly predicts depressive symptoms at T1 and at T2 above and beyond depressive symptoms and functional impairment. Also, the interaction between functional impairment and self-compassion at T0 significantly predicts depressive symptoms at T1, but not at T2.Conclusions: These findings expand the current knowledge on the role of self-compassion in CP in showing that self-compassion is a significant predictor of later depressive symptoms in CP and suggesting its potential role in buffering the impact of functional impairment in future levels of depressive symptoms.
21.	Carvalho, S. A., et al. (författare) Self-compassion in Acceptance and Commitment Therapy for chronic pain: a pilot study 2022 Ingår i: Scandinavian Journal of Pain. - : Walter de Gruyter GmbH. - 1877-8860 .- 1877-8879. ; 22:3, s. 631-638 Tidskriftsartikel (refereegranskat)abstract Objectives: Evidence shows that Acceptance and Commitment Therapy (ACT) is an empirically supported psychological approach for chronic pain (CP) management. Although self-compassion is not explicitly a target of ACT, it seems to be one mechanism of change in ACT for CP. However, research is lacking on the benefits of including explicit self-compassionate exercises in ACT for CP. The current study pilot tested a Compassionate ACT 8-session group program (COMP.ACT; n=9), as well as an ACT-only 8-session group program (ACT; n=7), in a sample of women with CP. Methods: The current study follows a quasi-experimental design, and conducts Reliable and Significant Change analyses comparing pre- to post-intervention scores of self-report measures. Results: No differences were found between conditions at baseline, nor between completers and drop-outs. Although preliminary, results showed COMP.ACT led to greater clinical improvements in depression and anxiety, while ACT led to greater improvements in stress and uncompassionate self-responding. Reliable and Significant Change analysis showed that some participants improved significantly (in psychopathological symptoms, valued living and uncompassionate self-responding) in both conditions, while the majority did not change significantly. Conclusions: More research is needed to conclude whether explicit self-compassion exercises are useful in ACT for CP. Limitations and implications are further discussed.

Development and validation of the Inflexible Eating Questionnaire 2017 Ingår i: Appetite. - : Elsevier. - 0195-6663 .- 1095-8304. ; 114, s. 146-154 Tidskriftsartikel (refereegranskat)abstract This study presents the Inflexible Eating Questionnaire (IEQ), which measures the inflexible adherence to subjective eating rules.The scale's structure and psychometric properties were examined in distinct samples from the general population comprising both men and women.IEQ presented an 11-item one-dimensional structure, revealed high internal consistency, construct and temporal stability, and discriminated eating psychopathology cases from non-cases. The IEQ presented significant associations with dietary restraint, eating psychopathology, body image inflexibility, general psychopathology symptoms, and decreased intuitive eating. IEQ was a significant moderator on the association between dietary restraint and eating psychopathology symptoms.Findings suggested that the IEQ is a valid and useful instrument with potential implications for research on psychological inflexibility in disordered eating.
23.	Evans, David A.D., et al. (författare) An expanding list of reliable paleomagnetic poles for Precambrian tectonic reconstructions 2021 Ingår i: Ancient Supercontinents and the Paleogeography of Earth. - : Elsevier. ; , s. 605-639 Bokkapitel (refereegranskat)abstract We present a compilation of reliable Precambrian paleomagnetic poles from three successive international workshops (in years 2009, 2014, 2017), comprising paleomagnetists specializing in Precambrian tectonic reconstructions. The working groups compiled lists of two global classes of poles, published through the end of 2017. “Grade-A” results are judged to provide essential constraints on tectonic reconstructions; “Grade-B” poles are judged to be suggestive of high-quality, but not yet demonstrated to be primary, or perhaps lacking precise geochronologic or other constraints. Our catalog documents a resurgence of high-quality data acquisition in recent years, and highlights specific cratons and time intervals that are most lacking in the data needed to reconstruct those blocks through supercontinental cycles.

Moderate to high palaeolatitude of the São Francisco/Congo craton at 920 Ma 2015. - 1 Ingår i: Geological Society Special Publication. - 0305-8719. ; 424:1, s. 167-190 Bokkapitel (refereegranskat)abstract Moderate to high palaeolatitudes recorded in mafic dykes, exposed along the coast of Bahia, Brazil, are partly responsible for some interpretations that the São Francisco/Congo craton was separate from the low-latitude Rodinia supercontinent at about 1050 Ma. We report new palaeomagnetic data that replicate the previous results. However, we obtain substantially younger U-Pb baddeleyite ages from five dykes previously thought to be 1.02-1.01 Ga according to the 40Ar/39Ar method. Specifically, the so-called «A-normal» remanence direction from Salvador is dated at 924.2±3.8 Ma, within error of the age for the «C» remanence direction at 921.5±4.3 Ma. An «A-normal» dyke at Ilh»us is dated at 926.1±4.6 Ma, and two «A-normal» dykes at Olivença have indistinguishable ages with best estimate of emplacement at 918.2±6.7 Ma. We attribute the palaeomagnetic variance of the «A-normal» and «C» directions to lack of averaging of geomagnetic palaeosecular variation in some regions. Our results render previous 40Ar/39Ar ages from the dykes suspect, leaving late Mesoproterozoic palaeolatitudes of the São Francisco/Congo craton unconstrained. The combined «A-normal» palaeomagnetic pole from coastal Bahia places the São Francisco/Congo craton in moderate to high palaeolatitudes at c. 920 Ma, allowing various possible positions of that block within Rodinia.

(författare) Usability Study of the iACTwithPain Platform : An Online Acceptance and Commitment Therapy and Compassion-Based Intervention for Chronic Pain 2022 Ingår i: Frontiers in Psychology. - : Frontiers Media S.A.. - 1664-1078. ; 13 Tidskriftsartikel (refereegranskat)abstract Background: This pilot study aims to test the usability of the iACTwithPain platform, an online ACT-based intervention for people with chronic pain, to obtain information on which intervention and usability aspects need improvement and on expected retention rates.Methods: Seventy-three Portuguese women with chronic pain were invited to complete the first three sessions of the iACTwithPain intervention assess their quality, usefulness and the platform's usability. Twenty-one accepted the invitation. Additionally, eight healthcare professionals working with chronic medical conditions assessed the platform and the intervention from a practitioner's point of view.Results: This study presented a considerable attrition rate (71.43%) among chronic pain participants, with six completers. There were no significant differences in demographic or clinical variables between dropouts and completers except for completed education (participants who dropped out presented less education than completers). Reasons for dropout were related to difficult personal events occurring during the time of the intervention, lack of time, or having forgotten. There seemed to be an overall satisfaction with both the intervention, its contents and form of presentation of information, and the platform, concerning its design, appearance, and usability. Real image videos were preferred over animations or audio by chronic pain participants. Healthcare professionals emphasized the appealing and dynamic aspects of the animation format.Conclusion: This study informs the ongoing improvement of the iACTwithPain platform and provides valuable information on aspects researchers should consider while developing online psychological interventions for chronic pain. Further implications are discussed.

An online study involving 319 adults (75% female, mean (SD) 14.06 (15.57) years of symptoms) completed the Gastrointestinal Symptom Rating Scale, Brief Illness Perceptions Questionnaire, Fear of Contracting COVID-19 Scale, Brief-COPE, Depression, Anxiety and Stress Scale, and the EUROHIS-QOL. The extended CSM had an excellent fit (chi(2) (9) = 17.06, p = .05, chi(2)/N = 1.90, RMSEA = 0.05, SRMR = 0.04, CFI = .99, TLI = .97, GFI = 0.99), indicating the influence of gastrointestinal symptoms on QoL was mediated by illness perceptions, fear of COVID-19, adaptive and maladaptive coping, and psychological distress. Interventions targeting the fear of COVID-19 in the context of an individual's perceptions will likely enhance QoL during the pandemic.

Therefore, the aim of this study was to compare the fear of coronavirus-19 in patients with inflammatory bowel disease to other gastrointestinal conditions and how the fear of COVID-19 manifests across different demographical backgrounds among inflammatory bowel disease respondents. Methods: Participants with gastrointestinal conditions (age >= 18) were recruited from 27 countries. Demographic, clinical, and psychosocial information was collected. An adapted scale for inflammatory bowel disease patients measuring the fear of coronavirus-19 and gastrointestinal-specific fear of coronavirus-19 was used. Results: In 831 participants (312 inflammatory bowel disease), only significant increases in gastrointestinal-fear of coronavirus-19 were found in between inflammatory bowel disease and other gastrointestinal conditions (mean [standard deviation]: 13.5 [5.5] vs 10.9 [5.0], P <.01). Among inflammatory bowel disease respondents, persons on sick leave had significantly more fear of coronavirus-19 than those employed (median [IQR], 31.0 [28.5-39.5] vs 26.0 [20.0-33.0], P =.035) and significantly more gastrointestinal-fear of coronavirus-19 compared to the employed (18.0 [14.5-22.0] vs 13.0 [9.0-17.0], P =.033) or respondents outside of the labor market (12.0 [7.0-16.0], P =.022). Persons living in a rural setting had significantly more fear of coronavirus-19 compared to persons living in regional setting (29.5 [22.0-37.8] vs 25.0 [20.0-31.3], P =.007) and gastrointestinal-fear of coronavirus-19 (15.0 [11.0-19.8] vs 12.0 [9.0-16.0], P =.02). Conclusion: Respondents with inflammatory bowel disease are more afraid of coronavirus-19 regarding their disease; especially, persons on sick leave or persons living in a rural setting. This should be taken into consideration to personalize the support that health care providers can offer in mitigating fear related to coronavirus-19.

Oxygen and sunlight availability are key factors promoting microbial diversity throughout the water column. Ocean currents also play a major role in the physicochemical stratification, carrying oxygen down to deeper zones as well as moving deeper water masses up towards shallower depths. Water samples within a 50-km radius in a pockmark location of the southwestern Atlantic Ocean were collected and the prokaryotic communities from different water depths - chlorophyll maximum, oxygen minimum and deep-sea bottom (down to 1355 m) - were described. At phylum level, Proteobacteria were the most frequent in all water depths, Cyanobacteria were statistically more frequent in chlorophyll maximum zone, while Thaumarchaeota were significantly more abundant in both oxygen minimum and bottom waters. The most frequent microorganism in the chlorophyll maximum and oxygen minimum zones was a Pelagibacteraceae operational taxonomic unit (OTU). At the bottom, the most abundant genus was the archaeon Nitrosopurnilus. Beta diversity analysis of the 16S rRNA gene sequencing data uncovered in this study shows high spatial hetero-geneity among water zones communities. Our data brings important contribution for the characterisation of oceanic microbial diversity, as it consists of the first description of prokaryotic communities occurring in different oceanic water zones in the southwestern Atlantic Ocean.

Nevertheless, although there is meta-analytical evidence on the efficacy of face-to-face ACT, no reviews have been performed on online ACT in this population. The aim of this meta-analysis is to determine the efficacy of online ACT for adults with chronic pain, when compared with controls. PubMed, PsycINFO, CENTRAL, and Web of Knowledge were searched for randomized controlled trials (RCTs) of online-delivered ACT for chronic pain. Effects were analyzed at post-treatment and follow-up, by calculating standardized mean differences. Online-delivered ACT was generally favored over controls (5 RCTs, N = 746). At post-treatment, medium effects for pain interference and pain acceptance, and small effects for depression, mindfulness, and psychological flexibility were found. A medium effect for pain interference and acceptance, and small effects for pain intensity, depression, anxiety, mindfulness, and psychological flexibility were found at followup. ACT-related effects for pain interference, pain intensity, mindfulness, and anxiety increased from post-treatment to follow-up. Nevertheless, the current findings also highlight the need for more methodologically robust RCTs. Future trials should compare online ACT with active treatments, and use measurement methods with low bias.Perspective: This is the first meta-analytical review on the efficacy of online ACT for people with chronic pain. It comprises 5 RCTs that compared online ACT with active and/or inactive controls. Online ACT was more efficacious than controls regarding pain interference, pain intensity, depression, anxiety, mindfulness, and psychological flexibility.

Several constructs such as experiential avoidance, cognitive fusion, shame, and self-criticism have recently emerged as potential intervention targets to improve mental health in IBD. Psychotherapeutic models such as Acceptance and Commitment Therapy and compassion-based interventions are known to target these constructs. In this protocol, we aim to describe a two-arm Randomized Controlled Trial (RCT) testing the efficacy of an ACT and compassion-focused intervention named Living with Intention, Fullness, and Engagement with Inflammatory Bowel Disease (LIFEwithIBD) intervention + Treatment As Usual (TAU) vs. TAU in improving psychological distress, quality of life, work and social functioning, IBD symptom perception, illness-related shame, psychological flexibility, self-compassion, disease activity, inflammation biomarkers, and gut microbiota diversity. Methods: This trial is registered at (Identifier: NCT03840707, date assigned 13/02/2019). The LIFEwithIBD intervention is an adaptation to the IBD population of the Mind programme for people with cancer, an acceptance, mindfulness, and compassion-based intervention designed to be delivered in a group format. The LIFEwithIBD intervention's structure and topics are presented in this protocol. Participants were recruited at the Gastroenterology Service of the Coimbra University Hospital between June and September 2019. Of the 355 patients screened, 61 participants were selected, randomly assigned to one of two conditions [experimental group (LIFEwithIBD + TAU) or control group (TAU)] and completed the baseline assessment. Outcome measurement took place at baseline, post-intervention, 3- and 12-month follow-ups. Discussion: Results from this RCT will support future studies testing the LIFEwithIBD intervention or other acceptance and/or compassion-based interventions for IBD.

Compassion-focused therapy (CFT) reduces psychological distress, especially in individuals with high levels of shame and self-criticism, but few studies have explored CFT in CI. Additionally, studies almost exclusively compared ACT and CFT with inactive controls (wait-list; treatment as usual). Also, there is an interest in developing cost-effective mental health solutions, such as low-intensity online psychological interventions. This randomized controlled trial (RCT) aimed to assess the acceptability and compare the efficacy of four-session online ACT (n = 25) and CFT (n = 24) interventions in a sample of people with CI. Results showed both interventions were acceptable, with attrition rates at post-intervention comparable to those found in similar studies (around 50%). Intention-to-treat analyses showed that participants presented significantly less illness-related shame, less uncompassionate self-responding and more valued living after the intervention, although no difference was found between conditions. Results were sustained at 3- and 6-month follow-up. Results did not find statistical differences between conditions through reliable change index (RCI). Correlation between demographics and RCI showed that, at post-intervention, younger participants presented more behavioural awareness, men presented more valued action, and participants with CI for shorter periods presented less uncompassionate self-responding and less anxiety. Results suggest that low-intensity (four sessions) online ACT and CFT are cost-effective approaches to promote mental health of individuals with CI. Results and limitations are thoroughly discussed.

The sample (N = 266; 72.6% women) was obtained through paper-pencil and online collection methods in the general Portuguese population. Confirmatory factor analysis, reliability analyses, and convergent and divergent analyses were conducted. A mediation analysis of the effects of self-as-distinction and self-as-observer on depression symptoms through openness to experience, behavioral awareness, and valued action (while controlling for brooding) was performed using PROCESS. Items 8, 12 and 15 were removed to achieve the best model fit, which resulted in a 12-item final version of the SEQ. This version appears to be a psychometrically valid two-dimensional measure of self-as-distinction and self-as-observer, as well as a one global measure of self-as-context. Results from mediation analyses suggested that the relationship of self-as-observer and self-as-distinction with depressive symptoms is mediated by the ability to be behaviorally aware and to act according to personal values, but not by the ability to be open to experience. The behaviorally-oriented aspects of psychological flexibility seem to have particular importance on the presentation of depressive symptoms. More studies are nonetheless needed to analyze SEQ's structure and validity in order to attain a consensual version of the questionnaire.

Materials and Methods: An electronic search was undertaken in February 2019 using five databases. Publications reporting cases of patients with OLP and rehabilitated with implant-supported oral prosthesis were included. Results: Twenty-two publications were included (230 patients, 615 implants). The overall implant failure rate was 13.9% (85/610). In patients with oral squamous cell carcinoma (OSCC) the failure rate was 90.6% (29/32), but none of these implants lost osseointegration; instead, the implants were removed together with the tumor. One study presented a very high implant failure rate, 76.4% (42/55), in patients with "active lichen planus", with all implants failing between 7-16 weeks after implant placement, and its conflicting and incongruent results are discussed in detail. There was a statistically significant difference between the failure rates in implants installed in different jaws (maxilla/mandible) and when implants of different surfaces were used (turned/moderately rough), but not between patients with reticular or erosive OLP types, or between male and female patients. If OSCC patients and the cases of the latter study are not considered, then the failure rate becomes very low (2.7%, 14/523). The time between implant placement and failure was 25.4 +/- 32.6 months (range 1-112). The mean +/- SD follow-up was 58.9 +/- 26.7 months (1-180). Conclusions: When the results of the one study with a very high failure rate and of the cases that developed OSCC are not considered, the dental implant failure rate in OLP patients was 2.7% after a follow-up of approximately five years. Recommendations are given when treating OLP patients with dental implants.

However, the underlying psychological processes that contribute to this association are still unclear. The present study aims to explore the mediating role of external shame and fears of receiving compassion on the associations of the number of major life events and their appraisals by the individual with depressive symptoms. Participants were 400 Portuguese-speaking adults from the general population (121 men and 279 women) with ages between 18 and 65 years, that completed self-report measures. Correlation analysis showed significant and positive associations between the number of major life events that occurred in the previous year and the positive and negative appraisal of such events, external shame, fears of receiving compassion, and depressive symptoms. Path analysis revealed that external shame and fears of receiving compassion fully mediated the effects of number of life events on depressive symptoms. Furthermore, results showed a direct effect of negative appraisal of major life events on depressive symptoms. This study sheds light on the psychological processes that may underlie the relationship between the cumulative number of major life events and depressive symptoms. Specifically, it suggests that the occurrence of major life events can impact on depressive symptoms when associated with feelings of shame and fears of receiving compassion from others.

Students with chronic illness presented higher levels of anxiety and experiential avoidance and lower levels of quality of life. The association between anxiety and psychological quality of life was partially explained by experiential avoidance and committed action. This path model was shown to be invariant between the two groups of students.

In order to improve our knowledge about the Mesoproterozoic evolution of Columbia, a paleomagnetic study was carried out on the 1420 Ma Indiavaí mafic intrusive rocks that crosscut the polycyclic Proterozoic basement of the SW Amazonian Craton, in southwestern Mato Grosso State (Brazil). Alternating field and thermal demagnetization revealed south/southwest ChRM directions with downward inclinations for sixteen analyzed sites. These directions are probably carried by SD/PSD magnetite with high coercivities and high unblocking temperatures as indicated by additional rock magnetic tests, including thermomagnetic data, hysteresis data and the progressive acquisition of isothermal remanent magnetization. Different stable magnetization components isolated in host rocks from the basement 10 km NW away to the Indiavaí intrusion, further support the primary origin of the ChRM. A mean of the site mean directions was calculated at Dm = 209.8°, Im = 50.7° (α95 = 8.0°, K = 22.1), which yielded a paleomagnetic pole located at 249.7°E, -57.0°N (A95 = 8.6°). The similarity of this pole with the recently published 1420 Ma pole from the Nova Guarita dykes in northern Mato Grosso State suggests a similar tectonic framework for these two sites located 600 km apart, implying the bulk rigidity of the Rondonian-San Ignacio crust at that time. Furthermore these data provide new insights on the tectonic significance of the 1100-1000 Ma Nova Brasilândia belt –a major EW feature that cuts across the basement rocks of this province, which can now be interpreted as intracratonic, in contrast to previous interpretation. From a global perspective, a new Mesoproterozoic paleogeography of Columbia has been proposed based on comparison of these 1420 Ma poles and a 1780 Ma pole from Amazonia with other paleomagnetic poles of similar age from Baltica and Laurentia, a reconstruction in agreement with geological correlations.

The tested model accounted for 62% of the variance of disordered eating. Path analyses results revealed that the three dimensions of fears of compassion impacted on disordered eating. Particularly, fear of expressing compassion for others presented a direct impact on disordered eating. Moreover, fears of self-compassion and fears of receiving compassion from others partially impacted on disordered eating attitudes and behaviours, through the mechanisms of social safeness and body image-focused shame. These findings suggested that women who present higher levels of fear of self-compassion and of receiving signs of affection and compassion from others tend to feel more insecure in their social group, which seem explain body shame and the engagement in disordered eating behaviours.Conclusions: This study highlights the pathogenic impact of fears of compassion on body image and eating attitudes and behaviours. The current data seem to offer relevant insights for research and clinical practice, by supporting the relevance of developing compassionate abilities and attitudes to target body image and eating-related difficulties.

Path analysis revealed that while controlling for body mass index, self-compassion mediated the impact of body dissatisfaction and unfavourable social comparisons on psychological quality of life. The path model accounted for 33per cent of psychological quality of life variance. Findings highlight the importance of self-compassion as a mechanism that may operate on the association between negative body image evaluations and young women's quality of life.

Although adherence to eating rules has been linked to disordered eating, literature has not yet explored how the inflexible subscription to those rules impacts on eating psychopathology. Therefore, the aim of the current study was to explore whether inflexible eating impacts on the relationships between weight and body image-related variables, and disordered eating.Participated in this study are 497 female adolescents from the community, aged between 14 and 18 years old, who completed self-report measures.Results revealed that the majority of the participants were dissatisfied with their weight and body shape. Moreover, 6.64 % of the participants demonstrated severe eating psychopathology. A path analysis revealed that BMI, body dissatisfaction and social comparisons based on physical appearance impact on disordered eating behaviours, through the mechanism of inflexible adherence to eating rules. This model explained 52 % of eating psychopathology's variance.Findings highlight the relevance of body image-related difficulties in adolescence and additionally they emphasise the importance of promoting more flexible attitudes towards eating in prevention and intervention programmes with female adolescents.

The aim of the current study was therefore to explore for the first time the role of body image-related cognitive fusion on these associations.Methods: This study comprised 779 young females who completed self-report measures. A path analysis was conducted to explore whether BMI, body dissatisfaction and feelings of inferiority based on physical appearance would impact on psychological QoL through body image-related cognitive fusion.Results: The model explained 39 % of psychological health, and revealed an excellent fit. Results showed that BMI did not directly impact on psychological health. Furthermore, the effects of increased body dissatisfaction and feelings of inferiority based on physical appearance on psychological health were fully and partially mediated by body image-related cognitive fusion, respectively.Conclusions: These findings suggest that the presence of body image-related negative experiences does not necessarily lead to impairment in women's QoL, which is rather dependent upon one's ability to observe these unwanted experiences as transient and subjective. Therefore, intervention programmes aiming at increasing women's QoL should focus on targeting emotional regulation processes in order to develop the ability to pursue life goals and values, even in the presence of unwanted experiences concerning body image.

In contrast, individuals who scarcely recall positive experiences may begin to believe that others see the self as inferior, inadequate and unattractive. In order to cope with a perceived loss of social desirability and achieve other's acceptance, individuals may become submissive, and women, particularly, may resort to the presentation of a perfect body image. Both mechanisms are defensive responses suggested to be associated with mental health difficulties, particularly disordered eating behaviors. The present study aimed at exploring the association between early memories of warmth and safeness with peers and eating psychopathology. Also, a path analysis was conducted to investigate the mediator role of submissiveness and perfectionistic self-presentation focused on body image on this association, in a sample of 342 female students. Results revealed that the absence of early positive memories with peers holds a significant effect over eating psychopathology's severity, and also that this effect is mediated through submissiveness and body image-related perfectionistic self-presentation. This model accounted for 13%, 19% and 51% of submissiveness, perfectionistic self-presentation of body image and eating psychopathology's variances, respectively, and showed excellent model fit.

(författare) Do shame and perfectionistic self-presentation explain the link between early affiliative memories and eating psychopathology? 2018 Ingår i: Psychology, Health & Medicine. - : Taylor & Francis. - 1354-8506 .- 1465-3966. ; 23:5, s. 628-634 Tidskriftsartikel (refereegranskat)abstract This study tested a model examining the impact that early affiliative memories (both with family and peers) on eating psychopathology, and whether these links are carried by the mechanisms of external shame and body image-related perfectionistic self-presentation, in a sample of 480 female college students. Path analyses' results revealed that this model accounted for 48% of disordered eating's variance and suggests that the lack of early positive emotional memories is associated with higher levels of shame (feelings of inferiority and unattractiveness), and with higher tendency to adopt body image-related perfectionistic strategies, that seem to explain excessive eating concern and rigid control of one's eating behaviors. This study offers important insights for future research and for the development of intervention programs, by revealing the importance of assessing and targeting shame and perfectionistic strategies and suggesting the importance of promoting adaptive emotion regulation strategies.
44.	Ferreira, Cláudia, et al. (författare) Explaining rigid dieting in normal-weight women : the key role of body image inflexibility 2016 Ingår i: Eating and Weight Disorders. - : Springer. - 1124-4909 .- 1590-1262. ; 21:1, s. 49-56 Tidskriftsartikel (refereegranskat)abstract Restrictive dieting is an increasing behavior presented by women in modern societies, independently of their weight. There are several known factors that motivate diet, namely a sense of dissatisfaction with one's body and unfavorable social comparisons based on physical appearance. However, dieting seems to have a paradoxical effect and has been considered a risk factor for weight gain and obesity in women and for maladaptive eating. Nevertheless, the study of the emotional regulation processes that explain the adoption of inflexible and rigid eating behaviors still remains little explored. In this line, the present study aims to explore why normal-weight women engage in highly rigid and inflexible diets. We hypothesize that body and weight dissatisfaction and unfavorable social comparisons based on physical appearance explain the adoption of inflexible eating rules, through the mechanisms of body image inflexibility. The current study comprised 508 normal-weight female college students. Path analyses were conducted to explore the study's hypotheses. Results revealed that the model explained 43 % of inflexible eating and revealed excellent fit indices. Furthermore, the unwillingness to experience unwanted events related to body image (body image inflexibility) mediated the impact of body dissatisfaction and unfavorable social comparisons on the adoption of inflexible eating rules. This study highlights the relevance of body image inflexibility to explain rigid eating attitudes, and it seems to be an important avenue for the development of interventions focusing on the promotion of adaptive attitudes towards body image and eating in young women.
45.	Ferreira, Cláudia, et al. (författare) Exploring drive for thinness as a perfectionistic strategy to escape from shame experiences 2015 Ingår i: The Spanish Journal of Psychology. - : Cambridge University Press. - 1138-7416 .- 1988-2904. ; 18 Tidskriftsartikel (refereegranskat)abstract Perfectionistic self-presentation defines the attempt at presenting the self as perfect through the public concealment of personal defects and/or through the display of attributes perceived as capable to gather positive attention of others. Although perfectionism has long been considered a central aspect of eating psychopathology mediational studies between this construct and these conditions are scarce. This study aimed at examining the mediational role of body image-related perfectionistic self-presentation in the effects of external shame and internal shame on drive for thinness, in a sample of young women. Results revealed body image-related perfectionistic self-presentation as a significant mediator (p <.05) of the relationships between external and internal shame, and drive for thinness. Furthermore, 86% and 69% of the effects of external shame and internal shame, respectively, were explained by their indirect effects through body image-related perfectionistic self-presentation on drive for thinness (95% CI). These results highlight that the control over eating may emerge as a maladaptive strategy to deal with shame when mediated by an endorsement in the belief that presenting a perfect body image is crucial to be accepted and valued by others. Study findings suggest that this perfectionistic strategy should be targeted while treating eating psychopathology.
46.	Ferreira, Cláudia, et al. (författare) Getting entangled with body image : Development and validation of a new measure 2015 Ingår i: Psychology and Psychotherapy. - : John Wiley & Sons. - 1476-0835 .- 2044-8341. ; 88:3, s. 304-316 Tidskriftsartikel (refereegranskat)abstract Objectives: Several studies have highlighted the role of cognitive fusion on human suffering and a wide range of psychopathological conditions. Namely, this process has been regarded as a core aspect in eating disorders. Nevertheless, the study of cognitive fusion on eating psychopathology is scarce and a measure that specifically concerns body image was still to be created. The present study aimed therefore at developing and validating such measure, the Cognitive Fusion Questionnaire - Body Image (CFQ-BI).Design and methods: The current study was conducted using different samples of both genders, collected in the general and student populations. The dimensionality of the CFQ-BI was tested through an exploratory factor analysis and a confirmatory factor analysis (CFA). The scale's internal reliability and other psychometric qualities were also analysed.Results: The CFQ-BI's final structure was one-dimensional and comprised 10 items that assess body image-related cognitive fusion. This final structure explained a total of 73.41% of the variance. The adequacy of the questionnaire was corroborated through a CFA which revealed that CFQ-BI presents good global and local adjustment values and goodness-of-fit indices. Results also showed that the CFQ-BI holds a very good internal consistency (=.96), convergent, divergent and temporal reliabilities, and is able to discriminate cases from non-cases of eating psychopathology.Conclusions: The CFQ-BI was thus established as a short, robust, and reliable measure of body image-related cognitive fusion. This new measure may correspond to a significant contribution to research and clinical practice in the field of body image and eating-related difficulties.
47.	Ferreira, Cláudia, et al. (författare) How do warmth, safeness and connectedness-related memories and experiences explain disordered eating? 2018 Ingår i: Eating and Weight Disorders. - : Springer. - 1124-4909 .- 1590-1262. ; 23:5, s. 629-636 Tidskriftsartikel (refereegranskat)abstract Literature suggested that the recall of early positive experiences have a major impact on the promotion of feelings of connectedness and social safeness, and seems to protect individuals against psychopathology. Recent research has also demonstrated that the absence of these positive rearing memories play a key role on disordered eating-related behaviours. The impact of early affiliative memories on disordered eating do not seem to be direct, and the mechanisms underlying this relationship are scarcely investigated. The present study aimed to clarify how memories of warmth and safeness explain the adoption of disordered eating attitudes, and tested the mediator role of social safeness, external shame and appearance-focused social comparison on aforementioned relationship, in a sample of 277 young women. The tested model explained 36% of eating psychopathology's variance and presented an excellent fit. Path analysis results indicated that the impact of rearing memories on eating psychopathology was fully mediated through the mechanisms of social safeness, external shame and appearance-focused social comparison. Specifically, these findings suggested that the extent to which positive rearing memories are associated with lower levels of disordered eating attitudes is influenced by the current feelings of social safeness and connectedness, which in turn are totally carried by decreased feelings of external shame and by lower endorsement on unfavourable comparison based on physical appearance with proximal targets (peers). These results seem to offer important insights for research and clinical work on body image and eating-related difficulties, suggesting the relevance of promoting warm and safe interactions with others.Level of evidenceLevel V, descriptive study.
48.	Ferreira, Cláudia, et al. (författare) Randomized controlled trial of an Acceptance and Commitment Therapy and compassion-based group intervention for persons with inflammatory bowel disease : the LIFEwithIBD intervention 2024 Ingår i: Frontiers in Psychology. - : Frontiers Media S.A.. - 1664-1078. ; 15 Tidskriftsartikel (refereegranskat)abstract Objectives: This study tested the acceptability and efficacy of an Acceptance and Commitment Therapy and compassion-based intervention (LIFEwithIBD) in people with IBD through a two-arm RCT.Methods: Participants were recruited at the Gastroenterology Department of the Coimbra University Hospital between June and September 2019. Of the 355 patients screened, those who accepted to participate were randomly assigned to one of two conditions: experimental group (LIFEwithIBD; n = 25) or control group (waitlist; n = 29). Participants completed self-report measures at baseline (T0), post-intervention (T1), and 3-month (T2) and 12-month (T3) follow-ups. Intervention acceptability was assessed. Efficacy was examined using intent-to-treat ANCOVA at post-intervention after adjusting for baseline values of depressive, anxiety, and stress symptoms (primary outcomes). Linear mixed models for all longitudinal outcomes were also analysed. Inflammatory and disease biomarkers were determined at T0 and T3.Results: Acceptability results revealed a high level of satisfaction and perceived usefulness regarding the intervention. Both groups experienced a significant decrease in stress symptoms and IBD symptom perception at T1. No significant differences were observed at follow-up for the primary outcomes. The experimental group reported significantly lower Crohn’s disease Symptom severity at T2 than the control group. Post-hoc analyses designed to mitigate floor effects revealed substantial treatment effects for the experimental group regarding anxiety symptoms. No significant differences were observed in clinical biomarkers from T0 to T3.Conclusion: The LIFEwithIBD intervention shows promising, although preliminary, benefits for managing disease activity and reducing anxiety symptoms in IBD patients with high severity of psychological distress.
49.	Ferreira, Cláudia, et al. (författare) Turning eating psychopathology risk factors into action : The pervasive effect of body image-related cognitive fusion 2014 Ingår i: Appetite. - : Elsevier. - 0195-6663 .- 1095-8304. ; 80, s. 137-142 Tidskriftsartikel (refereegranskat)abstract Body image dissatisfaction and unfavourable social comparisons are significant risk factors to eating psychopathology. Nevertheless, the impact of these negative experiences depends on the cognitive and emotional processes involved. Previous research has shown that cognitive fusion is a nuclear process linked to psychological inflexibility, but its role on body image and eating difficulties remains unclear. This study aims to explore a model of the mediational role of body image-related cognitive fusion (CF-BI) on the relationship between body dissatisfaction, unfavourable social comparisons, and eating psychopathology in a sample of 345 female students. Results from path analyses show that the impact of unfavourable social comparisons on eating psychopathology is fully mediated by CF-BI. Moreover, CF-BI also revealed a mediational effect on the relationship between body image dissatisfaction and the severity of eating symptoms, in spite of the fact that a direct effect of body dissatisfaction still exists. The tested model highlights the crucial role that cognitive fusion, in the specific domain of body image, plays in the relationship between risk factors and the severity of disordered eating attitudes and behaviours. Furthermore, these findings present empirical support for the relevance of addressing acceptance and cognitive defusion techniques to prevent and treat eating disorders.
50.	Ferreira, Cláudia, et al. (författare) Understanding the Role of Self-Judgment in the Association between Body Dissatisfaction and Quality of Life on Normal-Weight and Overweight Portuguese Women 2016 Ingår i: The Spanish Journal of Psychology. - : Cambridge University Press. - 1138-7416 .- 1988-2904. ; 19 Tidskriftsartikel (refereegranskat)abstract Literature has demonstrated the negative impact of body image dissatisfaction on women's quality of life. Nonetheless, it has been suggested that the relationship between body dissatisfaction and women's well-being is not linear, and that the processes that mediate this association remain unclear. This study aims to clarify the mediator role of self-judgment in the association between negative body image and psychological quality of life, in two groups: normal-weight and overweight women. This cross-sectional study comprised 200 normal-weight and 92 overweight female college students, aged between 18 and 24 years old, that completed self-report instruments of body dissatisfaction, self-judgment, and quality of life. Results showed that women who presented harsher self-judgment about their perceived failures tended to present lower levels in all quality of life domains. Also, results from mediation analyses indicated the relationship between body dissatisfaction and psychological quality of life was significantly mediated by the mechanisms of self-judgment in the two BMI groups (95% CI [-2.41 to -0.04]; 95% CI [-6.35 to -.89]). This mediational model accounted for 28.3% and 40.7% of psychological quality of life in the normal-weight and overweight groups, respectively. These results suggest that a lower ability to deal with one's failures or inadequacies (e.g., negative evaluation of body image) in a kind and accepting manner may significantly increase the negative impact of body dissatisfaction on one's psychological quality of life. In this way, it seems that, the focus of interventions should go beyond body dissatisfaction and also target the development of adaptive attitudes (opposed to self-critical attitudes) to deal with negative body-related experiences.
