RESUMO

Neuroimaging studies using autobiographical recall methods investigated the neural correlates of happy autobiographical memories (AMs). The scope of the present activation likelihood estimation (ALE) meta-analysis was to quantitatively analyze neuroimaging studies of happy AMs conducted with autobiographical recall paradigms. A total of 17 studies (12 fMRI; 5 PET) on healthy individuals were included in this meta-analysis. During recall of happy life events, consistent activation foci were found in the frontal gyrus, the cingulate cortex, the basal ganglia, the parahippocampus/hippocampus, the hypothalamus, and the thalamus. The result of this quantitative coordinate-based ALE meta-analysis provides an objective view of brain responses associated with AM recollection of happy events, thus identifying brain areas consistently activated across studies. This extended brain network included frontal and limbic regions involved in remembering emotionally relevant positive events. The frontal gyrus and the cingulate cortex may be responsible for cognitive appraisal processes during recollection of happy AMs, while the subthalamic nucleus and globus pallidus may be involved in pleasure reactions associated with recollection of happy life events. These findings shed light on the neural network involved in recalling positive AMs in healthy individuals, opening further avenues for future research in clinical populations with mood disorders.

RESUMO

Activation of Bruton's tyrosine kinase (BTK) has been shown to play a crucial role in the proinflammatory response of B cells and myeloid cells upon engagement with B cell, Fc, Toll-like receptor, and distinct chemokine receptors. Previous reports suggest BTK actively contributes to the pathogenesis of multiple sclerosis (MS). The BTK inhibitor Evobrutinib has been shown to reduce the numbers of gadolinium-enhancing lesions and relapses in relapsing-remitting MS patients. In vitro, BTK inhibition resulted in reduced phagocytic activity and modulated BTK-dependent inflammatory signaling of microglia and macrophages. Here, we investigated the protein expression of BTK and CD68 as well as iron accumulation in postmortem control (n = 10) and MS (n = 23) brain tissue, focusing on microglia and macrophages. MS cases encompassed active, chronic active, and inactive lesions. BTK+ and iron+ cells positively correlated across all regions of interests and, along with CD68, revealed highest numbers in the center of active and at the rim of chronic active lesions. We then studied the effect of BTK inhibition in the human immortalized microglia-like HMC3 cell line in vitro. In particular, we loaded HMC3 cells with iron-dextran and subsequently administered the BTK inhibitor Evobrutinib. Iron treatment alone induced a proinflammatory phenotype and increased the expression of iron importers as well as the intracellular iron storage protein ferritin light chain (FTL). BTK inhibition of iron-laden cells dampened the expression of microglia-related inflammatory genes as well as iron-importers, whereas the iron-exporter ferroportin was upregulated. Our data suggest that BTK inhibition not only dampens the proinflammatory response but also reduces iron import and storage in activated microglia and macrophages with possible implications on microglial iron accumulation in chronic active lesions in MS.

RESUMO

The co-occurrence between gambling disorder (GD) and problematic pornography use (PPU) has not yet been explored. Therefore, the present study compared (a) sociodemographic variables, (b) GD-related factors, (c) substance use, (d) psychopathology, (e) personality features, (f) impulsivity, and (g) emotion regulation between individuals with GD (GD group) and those with co-occurring GD and PPU (GD+PPU group). The sample consisted of 359 treatment-seeking individuals with GD: n = 332 individuals had GD only (GD group) and n = 37 individuals had GD and co-occurring PPU (GD+PPU group). GD severity, impulsivity, psychopathology, personality, emotion regulation, and other sociodemographic and clinical variables were assessed. No between-group differences in sociodemographic measures were observed. The GD+PPU group demonstrated greater GD severity and a higher likelihood of substance use compared to those without PPU. Furthermore, the presence of PPU was associated with worse psychopathology, higher impulsivity (except for lack of premeditation and positive urgency), more difficulties in emotion regulation (except for non-acceptance of emotions and limited access to emotions), and a personality profile characterized by lower levels of self-directedness and cooperativeness. The co-occurrence of GD and PPU seems associated with a more dysfunctional clinical profile.

RESUMO

BACKGROUND AND AIMS: Data regarding effectiveness and safety of JAK inhibitors and S1P receptor modulators in antibiotic refractory chronic pouchitis (CARP) are lacking. METHODS: This ECCO-CONFER project retrospectively collected JAK inhibitors or S1P receptor modulators treatments for CARP with at least 3-months follow up. The outcomes included corticosteroid and antibiotics-free clinical response and remission at three and twelve months, trend in mPDAI, endoscopic PDAI, CRP and calprotectin. RESULTS: Seventeen treatments in 15 patients were collected. Previous pouchitis treatments included infliximab (5/15), adalimumab (4/15), vedolizumab (9/15), and ustekinumab (5/15). Pooling data on JAK inhibitors (8 tofacitinib, 1 filgotinib and 6 upadacitinib), after 3 months (T3), steroid and antibiotics-free clinical response was achieved in 53.3% (8/15), steroid and antibiotics-free clinical remission was achieved in 40% (6/15). Of the patients with at least 12 months of follow-up, steroid and antibiotics-free clinical response was achieved in 50% (3/6) and remission in one patient (16.7%), endoscopic response in 50% (3/6), endoscopic remission in 50% (3/6). Of the two ozanimod treatments at T3, steroid and antibiotics-free clinical response was achieved in one patient, without remission; both discontinued ozanimod before T12. No side effects reported. CONCLUSIONS: Small molecules may represent a suitable option for CARP refractory to multiple biologics, deserving further investigation.

RESUMO

Peripheral contact to pathogen-associated molecular patterns (PAMPs) evokes a systemic innate immune response which is rapidly relayed to the central nervous system (CNS). The remarkable cellular heterogeneity of the CNS poses a significant challenge to the study of cell type and stimulus dependent responses of neural cells during acute inflammation. Here we utilized single nuclei RNA sequencing (snRNAseq), serum proteome profiling and primary cell culture methods to systematically compare the acute response of the mammalian brain to the bacterial PAMP lipopolysaccharide (LPS) and the viral PAMP polyinosinic:polycytidylic acid (Poly(I:C)), at single cell resolution. Our study unveiled convergent transcriptional cytokine and cellular stress responses in brain vascular and ependymal cells and a downregulation of several key mediators of directed blood brain barrier (BBB) transport. In contrast the neuronal response to PAMPs was limited in acute neuroinflammation. Moreover, our study highlighted the dominant role of IFN signalling upon Poly(I:C) challenge, particularly in cells of the oligodendrocyte lineage. Collectively our study unveils heterogeneous, shared and distinct cell type and stimulus dependent acute responses of the CNS to bacterial and viral PAMP challenges. Our findings highlight inflammation induced dysregulations of BBB-transporter gene expression, suggesting potential translational implications on drug pharmacokinetics variability during acute neuroinflammation. The pronounced dependency of oligodendrocytes on IFN stimulation during viral PAMP challenges, emphasizes their limited molecular viral response repertoire.

RESUMO

OBJECTIVE: The aim of the present study was to test the usefulness of an add-on serious video game approach (i.e., Playmancer) to treatment as usual (TAU) on reducing impulsive behaviours and psychopathology in individuals diagnosed with an eating disorder (ED). METHOD: Thirty-seven patients diagnosed with an ED according to the DSM-5 were included in the present randomized clinical trial (RCT; study record 35,405 in ClinicalTrials.gov) and were randomly assigned to either the TAU or TAU + Playmancer group. All participants completed a clinical interview. Impulsivity (UPPS-P self reported questionnaire and Stroop task) and general psychopathology (SCL-90-R) measures were assessed at: baseline, 4 weeks into treatment, at the end of TAU (after 16 weeks), and follow-up (2 years). In addition, patients in the experimental group underwent a total of nine sessions with Playmancer over the span of 3 weeks. RESULTS: Patients in both treatment groups (TAU + Playmancer or TAU) improved on Stroop task performance and psychological distress. Additionally, patients in TAU-Playmancer improved on the impulsive trait domain of lack of perseverance. No statistical differences were found regarding treatment outcomes (i.e., treatment adherence and remission of eating symptomatology) when comparing the two treatment groups. CONCLUSION: Our results suggest that the impulsivity associated with EDs should be addressed and could be modified, as some facets of trait impulsivity improved after Playmancer add-on treatment. Yet, there were no significant differences in treatment outcomes when comparing the two groups and further research needs to be conducted.

RESUMO

AIMS: Patients with inflammatory bowel disease (IBD) are known to be at increased risk for venous thrombosis, while their risk for arterial ischemic events is debated. The purpose of this study was to conduct a systematic review of the published literature on the risk of myocardial infarction (MI) in IBD patients and to identify any potential risk factors. METHODS: The present study was performed according to PRISMA, with a systematic search on PubMed, Cochrane, and Google Scholar. Risk of MI was the primary end point, while all causes of death and stroke were secondary endpoints. Both univariate and multivariate pooled analysis were performed. RESULTS: An overall population of 515,455 controls and 77,140 persons with IBD (26,852, 34.8% Crohn's disease, CD and 50,288, 65.2% ulcerative colitis, UC) was included. Mean age was similar across controls and IBD. Persons with CD and UC had lower rates of hypertension (14.5% vs. 14.6% vs. 25%), diabetes (2.9% vs. 5.2% vs. 9.2%) and dyslipidaemia (3.3% vs. 6.5% vs. 16.1%) compared to controls. Smoking did not significantly differ (17% vs. 17.5% vs. 10.6%). Pooled results of multivariate adjustment showed that, after a 5 years-follow-up, both CD and UC were at increased risk of MI (respectively HR 1.36 [1.12-1.64] and HR 1.24 [1.05-1.46]), of death (HR 1.55 [1.27-1.90] and HR 1.29 [1.01-1.64]), and of other CV disease as stroke (HR 1.22 [1.01-1.49] and HR 1.09 [1.03-1.15], all 95% CI). CONCLUSIONS: Persons with IBD are at increased risk of MI, despite a lower prevalence of the classic risk factors for MI (hypertension, diabetes, dyslipidemia).

RESUMO

Background and objectives: Craving is one of the main criteria for the diagnosis of substance use disorder according to the DSM-5; however, it is not included in the main criteria for gambling disorder (GD). In the present systematic review, we aimed to evaluate the available body of knowledge regarding gambling craving to help step forward to a consensus regarding this topic. Data sources: PsycINFO/PsycARTICLES and PubMed/Medline were used. Study eligibility criteria, participants, and interventions: (1) individuals of both genders who had a clinical diagnosis of GD in which the presence of gambling craving were studied by means of tasks or self-report tools; (2) we included three types of studies: (a) validation articles of craving psychometric tools in which GD was assessed; (b) articles in which craving-GD association was explored; and (c) treatment articles for GD in which craving was assessed. Results: n = 63 studies were finally included in the systematic review. Some studies described an association between craving- and gambling-related factors, and craving was also described as a predictor of GD severity, gambling episodes, chasing persistence and income-generating offenses. Gambling craving also seems to be associated with emotional states and negative urgency. Finally, some studies implemented specific interventions for GD and assessed its impact on reducing gambling craving. Conclusions: There is a growing body of knowledge on the relevant role of craving in gambling behavior and GD. Further studies are needed to reach a consensus on the diagnostic criterion for GD.

RESUMO

Nutritional rehabilitation with weight restoration is an important step in patients hospitalised for anorexia nervosa (AN). Naso-gastric feeding (NGF) should be considered when oral nutrition (OF) and oral nutritional supplementation (ONS) are insufficient. We evaluated the role of NGF on short- and long-term outcomes, considering weight gain, the length of hospitalisation (LOS) and the time to relapse. We report on the characteristics of patients under 18 years of age with AN admitted to the Department of Emergency and Acceptance of the Bambino Gesù Children's Hospital, IRCCS, Rome, between March 2019 and August 2022. Three hundred and fifteen patients were enrolled. We compared patients treated with NGF (group A) and patients without NGF (group B). Group A was characterised by a significantly lower BMI on admission and discharge, more frequent use of inpatient psychotropic therapy (IPDT) and longer hospital stay. The time to relapse was significantly longer in group A compared to group B. An early NGF setting correlates with a longer time to relapse and may be associated with a shorter LOS. A high caloric intake with a balanced nutritional formula provided by NGF allows an earlier recovery. The main advantages of this approach could be the rapid discharge of patients and a more effective psychological and social recovery.

RESUMO

BACKGROUND: Recent evidence is supporting the notion of a microbiological and immunological continuum on the gum-gut axis in health and disease. Therefore, the purpose of this study was to assess the prevalence and risk indicators of periodontitis in patients with Crohn's disease (CD) or ulcerative colitis (UC) compared to age- and sex-matched controls without inflammatory bowel disease (IBD). METHODS: A total of 180 IBD (117 CD, 60 UC, 3 IBD-unclassified) and 180 healthy controls were compared for their periodontitis diagnosis (Centers for Disease Control and Prevention/American Academy of Periodontology [CDC/AAP] case definition) and full-mouth periodontal parameters. In addition, explorative logistic regression models were performed. RESULTS: Significantly more patients with IBD had moderate/severe periodontitis (85.6% vs. 65.6%, p < 0.001) and severe periodontitis (36.7% vs. 25.6%, p < 0.001) than controls. Differences were higher in the 35-50 and 51-65 age groups, without significant changes between CD and UC. IBD subjects presented chances ∼3.5 higher of having moderate/severe periodontitis (p < 0.001). Significant variables associated with periodontitis in the whole sample were older age, presence of IBD, and higher full-mouth plaque scores, whereas in the IBD group they were male sex, IBD-associated surgery, and IBD duration and localization (pancolitis). Positive risk indicators for IBD were periodontitis severity and higher bleeding scores, while smoking was negatively associated with UC. CONCLUSIONS: Relevant associations between IBD and periodontitis were found, being modified by CD and UC clinical characteristics. Preventive and therapeutic strategies involving the gum-gut axis should be enforced in IBD patients.

RESUMO

Reactive neuroglia critically shape the brains response to ischemic stroke. However, their phenotypic heterogeneity impedes a holistic understanding of the cellular composition and microenvironment of the early ischemic lesion. Here we generated a single cell resolution transcriptomics dataset of the injured brain during the acute recovery from permanent middle cerebral artery occlusion. This approach unveiled infarction and subtype specific molecular signatures in oligodendrocyte lineage cells and astrocytes, which ranged among the most transcriptionally perturbed cell types in our dataset. Specifically, we characterized and compared infarction restricted proliferating oligodendrocyte precursor cells (OPCs), mature oligodendrocytes and heterogeneous reactive astrocyte populations. Our analyses unveiled unexpected commonalities in the transcriptional response of oligodendrocyte lineage cells and astrocytes to ischemic injury. Moreover, OPCs and reactive astrocytes were involved in a shared immuno-glial cross talk with stroke specific myeloid cells. In situ, osteopontin positive myeloid cells accumulated in close proximity to proliferating OPCs and reactive astrocytes, which expressed the osteopontin receptor CD44, within the perilesional zone specifically. In vitro, osteopontin increased the migratory capacity of OPCs. Collectively, our study highlights molecular cross talk events which might govern the cellular composition and microenvironment of infarcted brain tissue in the early stages of recovery.

RESUMO

Impulsivity, as a multidimensional construct, has been linked to eating disorders (EDs) and may negatively impact treatment response. The study aimed to identify the dimensions of impulsivity predicting poor remission of ED symptoms. A total of 37 ED patients underwent a baseline assessment of impulsive personality traits and inhibitory control, including the Stroop task and the emotional go/no-go task with event-related potentials (ERPs) analysis. The remission of EDs symptomatology was evaluated after 3 months of cognitive-behavioral therapy (CBT) and at a 2-year follow-up. Poor remission after CBT was predicted by poor inhibitory control, as measured by the Stroop task. At 2 years, the risk of poor remission was higher in patients with higher novelty seeking, lower inhibitory control in the Stroop and in ERPs indices (N2 amplitudes) during the emotional go/no-go task. The present results highlight inhibitory control negatively impacting both short- and long-term symptomatology remission in ED patients. On the other hand, high novelty seeking and ERPs indices of poor inhibition seem to be more specifically related to long-term remission. Therefore, a comprehensive assessment of the impulsivity dimension in patients with ED is recommended to tailor treatments and improve their efficacy.

RESUMO

Clinical and genomic studies have shown an overlap between neuropsychiatric disorders and insulin resistance (IR)-related somatic conditions, including obesity, type 2 diabetes, and cardiovascular diseases. Impaired cognition is often observed among neuropsychiatric disorders, where multiple cognitive domains may be affected. In this review, we aimed to summarise previous evidence on the relationship between IR-related diseases/traits and cognitive performance in the large UK Biobank study cohort. Electronic searches were conducted on PubMed, Scopus, and Web of Science until April 2022. Eighteen articles met the inclusion criteria and were qualitatively reviewed. Overall, there is substantial evidence for an association between IR-related cardio-metabolic diseases/traits and worse performance on various cognitive domains, which is largely independent of possible confoundings. The most consistent findings referred to IR-related associations with poorer verbal and numerical reasoning ability, as well as slower processing speed. The observed associations might be mediated by alterations in immune-inflammation, brain integrity/connectivity, and/or comorbid somatic or psychiatric diseases/traits. Our findings provide impetus for further research into the underlying neurobiology and possible new therapeutic targets.

RESUMO

Impulsivity has been associated with type 2 diabetes (T2D) and may negatively impact its management. This study aimed to investigate impulsive personality traits in an older adult population with T2D and their predicting role in long-term weight control and glycemic management, through glycated hemoglobin (HbA1c), following 3 years of intervention with a Mediterranean diet. The Impulsive Behavior Scale (UPPS-P) was administered as a measure of impulsive traits at baseline. Results showed higher total baseline scores of UPPS-P, and higher positive urgency in individuals with T2D, compared with those without T2D. The regression analysis in patients with T2D showed that sensation seeking and lack of perseverance predicted weight loss at follow-up. By contrast, impulsive traits did not predict follow-up levels of HbA1c. In conclusion, the present findings suggest that higher impulsive traits in individuals with T2D seem to affect long-term weight control, but not glycemic control.

RESUMO

Chronic intestinal disorders (CID) are characterized by persistent, or recurrent gastrointestinal (GI) signs present for at least three weeks. In human medicine, inflammatory bowel disease (IBD) is a group of chronic GI diseases and includes Crohn's disease (CD) and ulcerative colitis (UC). On the other hand, the general term chronic enteropathies (CE) is preferred in veterinary medicine. Different therapeutic approaches to these diseases are used in both humans and pets. This review is focused on the use of traditional therapies and nutraceuticals with specific antioxidant properties, for the treatment of CID in humans and animal patients. There is strong evidence of the antioxidant properties of the nutraceuticals included in this review, but few studies report their use for treating CID in humans and none in animals. Despite this fact, the majority of the nutraceuticals described in the present article could be considered as promising alternatives for the regular treatment of CID in human and veterinary medicine.

RESUMO

Impulsive choice, measured by delay discounting (DD) tasks, has been shown in patients with gambling disorders (GD). However, the impact of DD and treatment outcome has been scarcely explored in GD patients. The aims of this study were: (1) to examine the baseline association between DD and clinical variables in GD patients depending on their age and gambling preferences (strategic vs. non-strategic); and (2) to estimate the predictive role of DD on poorer outcomes of cognitive-behavioral therapy (CBT) when considering also the effect of other clinical variables. 133 treatment-seeking male GD patients were evaluated at baseline with a DD task and measures of GD severity, personality traits and psychopathology. Treatment outcome was measured in terms of dropout from CBT and relapses. Results showed baseline associations between DD and GD severity (correlation coefficient R = 0.408 among strategic gamblers and R = 0.279 among mixed gamblers) and between DD and positive/negative urgency (R = 0.330 for the youngest patients, R = 0.244 for middle age, and around R = 0.35 for gamblers who reported preferences for strategic games). Other personality traits such as high harm avoidance and low cooperativeness were also related to DD at baseline (R = 0.606 among strategic gamblers). Regarding treatment outcome, a steeper discount rate predicted a higher risk of relapses in strategic gamblers (odds ratio OR = 3.01) and middle-age ones (OR = 1.59), and a higher risk of dropout in younger gamblers (OR = 1.89), non-strategic gamblers (OR = 1.70) and mixed gamblers (R = 4.74). GD severity mediated the associations between age, DD, personality traits and poor CBT outcome. In conclusion, impulsive choice affects treatment response in individuals with GD and may interfere with it to a significant extent. Considering DD in GD, patients seeking treatment could help control its impact on treatment adherence and relapses.

RESUMO

PURPOSE: Since the beginning of COVID-19 pandemic, social distancing and home confinement had a significant impact on children, especially on those with eating disorders (ED). The primary objective of this retrospective study was to describe and analyze the demographic and clinical profiles of children presenting with ED during the COVID-19 pandemic. METHODS: We conducted a retrospective review of clinical charts of patients with ED younger than 18 years who accessed the emergency department of the Bambino Gesù Children's Hospital, Rome, between March 2019 and March 2021. Of these, we reported and compared the demographic, clinical and laboratory data before and after the COVID-19 pandemic and looked for predictors of ED severity. RESULTS: A total of 211 admissions for ED were recorded. The patients, mostly females (86.3%) were on average 14.1 years old. The mean weight loss on admission was 11 kg. Bradycardia was observed in 31.3% of the study sample. 16.6% of patients had an associated psychiatric disorder and 60.2% required psychotropic drugs. 68.7% of the patients required hospitalization. Respectively, 96 and 115 patients were admitted before and during the COVID-19 pandemic. The latter were hospitalized more (78.3 vs 57.3%; p = 0.001), yet for less time (19 vs 26 days; p = 0.004), had a higher mean serum creatinine (0.68 vs 0.47; p < 0.001) and were more frequently diagnosed with an associated psychiatric disorder (23.5 vs 8.3%; p = 0.003). CONCLUSION: Our study shows a significant increase of hospitalizations of children with ED during the COVID-19 pandemic, along with a shorter length of stay, more psychiatric comorbidities, and some distinctive features at the laboratory work-up, such as an increase of serum creatinine and/or a reduction of serum albumin. LEVEL OF EVIDENCE: III, evidence obtained from well-designed cohort or case-control analytic studies.

RESUMO

Impulsive and compulsive behaviors have both been observed in individuals with obesity. The co-occurrence of obesity and type 2 diabetes (T2D) is more strongly associated with impulsivity, although there are no conclusive results yet. A multidimensional assessment of impulsivity and compulsivity was conducted in individuals with obesity in the absence or presence of T2D, compared with healthy, normal-weight individuals, with highly impulsive patients (gambling disorders), and with highly compulsive patients (anorexia nervosa). Decision making and novelty seeking were used to measure impulsivity, and cognitive flexibility and harm avoidance were used for compulsivity. For impulsivity, patients with obesity and T2D showed poorer decision-making ability compared with healthy individuals. For compulsivity, individuals with only obesity presented less cognitive flexibility and high harm avoidance; these dimensions were not associated with obesity with T2D. This study contributes to the knowledge of the mechanisms associated with diabetes and its association with impulsive-compulsive behaviors, confirming the hypothesis that patients with obesity and T2D would be characterized by higher levels of impulsivity.

RESUMO

Poor performance in executive functions is observed in individuals with eating disorders (EDs). These impairments have usually been associated with the presence of comorbid psychopathology or with higher severity of EDs. However, few studies have explored the interaction between illness duration and deficits in executive functions. The present study investigates the association between ED duration and performance in decision-making, inhibitory control, and cognitive flexibility in the anorexia nervosa restrictive subtype (AN-R), bulimic/purging subtype (AN-BP), and binge spectrum disorders (BSDs) (namely, bulimia nervosa and binge eating disorder) among 116 women with EDs compared with 123 women healthy controls (HCs). Using cumulative survival analysis, we estimated the risk of deficits related to illness duration. Predictors of executive dysfunctions were assessed by regression analysis, including as potential predictors illness duration, severity of general psychopathology, and ED symptomatology. Results showed poor decision-making and cognitive flexibility in participants with EDs compared with HCs. ED duration was associated with poor inhibitory control in the AN-BP group and poor cognitive flexibility in the BSD group. The illness duration increased the risk of presenting early deficits in executive function. In decision-making and inhibitory control, the AN-R group showed the earliest deficits, whereas in cognitive flexibility it was the BSD group. ED duration predicted impaired cognitive flexibility in the BSD group and impaired inhibitory control in the AN-BP group, whereas the severity of general psychopathological symptoms was a predictor of impaired cognitive flexibility in individuals with AN-R. These results highlight the relevance of illness duration in executive dysfunctions in EDs.
